It is especially important to upgrade for Redis - Cluster users and for users running Redis in their laptop - since a cross-scripting attack is fixed in this release. - -Main bugs fixes and improvements in this release: - -1. MIGRATE could incorrectly move keys between Redis Cluster nodes by turning - keys with an expire set into persisting keys. This bug was introduced with - the multiple-keys migration recently. It is now fixed. Only applies to - Redis Cluster users that use the resharding features of Redis Cluster. - -2. As Redis 4.0 beta and the unstable branch already did (for some months at - this point), Redis 3.2.7 also aliases the Host: and POST commands to QUIT - avoiding to process the remaining pipeline if there are pending commands. - This is a security protection against a "Cross Scripting" attack, that - usually involves trying to feed Redis with HTTP in order to execute commands. - Example: a developer is running a local copy of Redis for development - purposes. She also runs a web browser in the same computer. The web browser - could send an HTTP request to http://127.0.0.1:6379 in order to access the - Redis instance, since a specially crafted HTTP requesta may also be partially - valid Redis protocol. However if POST and Host: break the connection, this - problem should be avoided. IMPORTANT: It is important to realize that it - is not impossible that another way will be found to talk with a localhost - Redis using a Cross Protocol attack not involving sending POST or Host: so - this is only a layer of protection but not a definitive fix for this class - of issues. - -3. A ziplist bug that could cause data corruption, could crash the server and - MAY ALSO HAVE SECURITY IMPLICATIONS was fixed. The bug looks complex to - exploit, but attacks always get worse, never better (cit). The bug is very - very hard to catch in practice, it required manual analysis of the ziplist - code in order to be found. However it is also possible that rarely it - happened in the wild. Upgrading is required if you use LINSERT and other - in-the-middle list manipulation commands. - -4. We upgraded to Jemalloc 4.4.0 since the version we used to ship with Redis - was an early 4.0 release of Jemalloc. This version may have several - improvements including the ability to better reclaim/use the memory of - system. - -The following is the list of commits: - -antirez in commit 3876d98: - Ziplist: insertion bug under particular conditions fixed. - 1 file changed, 9 insertions(+), 1 deletion(-) - -antirez in commit 153f2f0: - Jemalloc updated to 4.4.0. - 150 files changed, 17271 insertions(+), 6356 deletions(-) - -miter in commit ca532c9: - Change switch statment to if statment - 1 file changed, 2 insertions(+), 4 deletions(-) - -oranagra in commit a735035: - fix rare assertion in DEBUG DIGEST - 1 file changed, 1 insertion(+), 1 deletion(-) - -Itamar Haber in commit b917e3f: - Verify pairs are provided after subcommands - 1 file changed, 1 insertion(+), 1 deletion(-) - -antirez in commit 1177cf6: - Avoid geo.c warning in initialization. - 1 file changed, 1 insertion(+), 1 deletion(-) - -antirez in commit 874804d: - Security: Cross Protocol Scripting protection. - 3 files changed, 27 insertions(+), 2 deletions(-) - -antirez in commit 273cd7f: - Ziplist: remove static from functions, they prevent good crash reports. - 1 file changed, 14 insertions(+), 14 deletions(-) - -Jan-Erik Rediger in commit 389b9f5: - Initialize help only in repl mode - 1 file changed, 5 insertions(+), 5 deletions(-) - -Yossi Gottlieb in commit 1370a88: - Fix redis-cli rare crash. - 1 file changed, 4 insertions(+) - -antirez in commit 68aab8e: - MIGRATE: Remove upfront ttl initialization. - 1 file changed, 3 insertions(+), 4 deletions(-) - -Jan-Erik Rediger in commit 788e892: - Reset the ttl for additional keys - 1 file changed, 1 insertion(+) - -================================================================================ -Redis 3.2.6 Released Tue Dec 06 09:33:29 CET 2016 -================================================================================ - -Upgrade urgency MODERATE: GEORADIUS, BITFIELD and Redis Cluster minor fixes. - -This release mainly fixes three bugs: - -1.

Redis 3.2.2 is finally out with non trivial bugfixes and a few new -features. Let's start from the bugs: - -1. There was a bug in the List type implementation, able to cause the - crash of the server under certain (non trivial to replicate) circumstances - when the LSET command was used. Now the bug is fixed and a new stress tester - that was able to easily trigger the bug was added to the test suite. - -2. Redis Sentinel, when monitoring multiple masters, could crash after - a Sentinel address update event. - -3. Redis Sentinel now checks slaves INFO state more often when disconnected. - This is not really a bug fix, but may allow to more easily detect that - a slave is able to fail over its master reducing certain delays. - -4. It was possible, under a variety of conditions, that the AOF and RDB children - process could spawn at the same time. This is known to trash disk I/O, - AOF performances, and to ultimately create latency in the Redis server. - Normally Redis avoids to have the two writing children at the same time, but - there were edge cases discovered by Oran Agra (that also co-authored the - fix with me) where the double-fork could happen. In order to fix this bug - non trivial changes to the replication code were operated, however it was - important to back port this fix into 3.2.2 because the bug could lead to - bad latency experiences in certain cases. - -5. Many GEORADIUS bugs are now fixed \o/. This started as a failing CI - test. I grepped for more clues and there were a number of random failures - in the points reported by GEORADIUS. The errors were found to be related - to three different bugs (one of these was a bug in the test itself). - It's not a critical bug: the effect is to, sometimes, don't report objects - that are near the radius, but only with specific sets of coordinates - and radius settings. However now the issues are fixed and the error - vectors were added as regression tests. - -And now the good news (not that bug fixes are not good...), that is, the -new features! - -1. Now slaves support the slave-announce-ip and slave-announce-port options. - Using these features a slave can be reported by the master `INFO` output - and `ROLE` command as having arbitrary IP and port. This allows to have - Sentinel deployments when working with containers or NAT-ed environments - more easily. - -2. The RDB check utlity is now part of Redis and uses the same RDB code that - Redis uses in order to load the dataset in memory, so a given version - of Redis is always able to check the RDB it produced... without another - external check tool which is supposed to be taken in sync with the - rdb.c implementation. This in turn also means that the new RDB checking - is able to spot more complex bugs, since it really loads the dataset - instead of just skipping bytes. - -About the redis-check-dump utility, now it is also able to show certain -information about the RDB file, like the version that produced it, when -it was produced, and so forth. Example: - - ./redis-check-rdb dump.rdb - [offset 0] Checking RDB file dump.rdb - [offset 32] AUX FIELD redis-ver = '3.2.2' - [offset 46] AUX FIELD redis-bits = '64' - [offset 58] AUX FIELD ctime = '1469710178' - [offset 73] AUX FIELD used-mem = '1186528' - -The ability to check how much memory was used by the instance that produced -the RDB file can be especially useful. - -For credits and the full change log, see the list of commits below, that was -modified in order to be a bit less verbose compared to the last releases. - -Enjoy! -Salvatore - -antirez in commit 0a45fbc: - Ability of slave to announce arbitrary ip/port to master. - 6 files changed, 129 insertions(+), 17 deletions(-) - -antirez in commit c3982c0: - redis-benchmark: new option to show server errors on stdout. - 1 file changed, 17 insertions(+), 1 deletion(-) - -antirez in commit fdafe23: - Multiple GEORADIUS bugs fixed. - 6 files changed, 177 insertions(+), 21 deletions(-) - -antirez in commit a1bfe22: - Replication: when possible start RDB saving ASAP. - 1 file changed, 8 insertions(+), 2 deletions(-) - -antirez in commit 7ca69af: - Sentinel: new test unit 07 that tests master down conditions. - 1 file changed, 68 insertions(+) - -antirez in commit 5b5e652: - Sentinel: check Slave INFO state more often when disconnected. - 2 files changed, 10 insertions(+), 3 deletions(-) - -antirez in commit 21cffc2: - Avoid simultaneous RDB and AOF child process. - 4 files changed, 51 insertions(+), 8 deletions(-) - -antirez in commit 017378e: - Replication: start BGSAVE for replication always in replicationCron(). - 1 file changed, 15 insertions(+), 12 deletions(-) - -antirez in commit 940be9a: - Regression test for issue #3333. - 1 file changed, 6 insertions(+) - -antirez in commit 21736b4: - getLongLongFromObject: use string2ll() instead of strict_strtoll(). - 1 file changed, 1 insertion(+), 6 deletions(-) - -antirez in commit 0b748e9: - redis-cli: check SELECT reply type just in state updated. - 1 file changed, 1 insertion(+), 1 deletion(-) - -sskorgal in commit 1158386: - Fix for redis_cli printing default DB when select command fails. - 1 file changed, 1 insertion(+), 1 deletion(-) - -antirez in commit 026f9fc: - Sentinel: fix cross-master Sentinel address update. - 1 file changed, 9 insertions(+), 2 deletions(-) - -antirez in commit 11523b3: - CONFIG GET is now no longer case sensitive. - 1 file changed, 12 insertions(+), 12 deletions(-) - -antirez in commit f5a7f4f: - Fix test for new RDB checksum failure message. - 1 file changed, 1 insertion(+), 1 deletion(-) - -antirez in commit 4c6ff74: - Make tcp-keepalive default to 300 in internal conf. - 1 file changed, 1 insertion(+), 1 deletion(-) - -antirez in commit 27dbec2: - In Redis RDB check: more details in error reportings. - 1 file changed, 24 insertions(+), 13 deletions(-) - -antirez in commit 41f3004: - In Redis RDB check: log decompression errors. - 2 files changed, 23 insertions(+), 2 deletions(-) - -antirez in commit 278fe3e: - In Redis RDB check: log object type on error. - 1 file changed, 27 insertions(+), 2 deletions(-) - -antirez in commit a117dfa: - Added a trivial program to randomly corrupt RDB files in /utils. - 1 file changed, 44 insertions(+) - -antirez in commit f5110c3: - In Redis RDB check: minor output message changes. - 1 file changed, 4 insertions(+), 1 deletion(-) - -antirez in commit 35b18bf: - In Redis RDB check: better error reporting. - 4 files changed, 71 insertions(+), 14 deletions(-) - -antirez in commit f578f08: - In Redis RDB check: initial POC. - 2 files changed, 189 insertions(+), 647 deletions(-) - -tielei in commit 7f1e1ca: - A string with 21 chars is not representable as a 64-bit integer. - 1 file changed, 2 insertions(+), 2 deletions(-) - -antirez in commit 7a3a595: - Test: new randomized stress tester for #3343 alike bugs. - 1 file changed, 27 insertions(+), 2 deletions(-) - -antirez in commit c75ca10: - Stress tester WIP. - 1 file changed, 3 insertions(+) - -antirez in commit 2c3fcf8: - Regression test for issue #3343 exact min crash sequence. - 1 file changed, 16 insertions(+) - -antirez in commit 7041967: - Fix quicklistReplaceAtIndex() by updating the quicklist ziplist size. - 1 file changed, 1 insertion(+) - -================================================================================ -Redis 3.2.1 Released Fri Jun 17 15:01:56 CEST 2016 -================================================================================ - -Upgrade urgency HIGH: Critical fix to Redis Sentinel, due to 3.2.0 regression - compared to 3.0. - -Hey, this is Redis 3.2.1, and this release should bring some grain of -maturity to Redis 3.2. The list of commits following this note will tell -you the details, but the main things addressed in this release are the -following: - -1. A critical bug in Sentinel was hopefully fixed. During the big 3.2 - refactoring of Redis Sentinel, in order to implement connection sharing - to make Sentinel able to scale better (few Sentinels to monitor many - masters), a bug was introduced that mis-counted the number of pending - commands in the Redis link. This in turn resulted into an inability to talk - with certain Redis instances. A common result of this bug was the inability - of Redis Sentinel to reconfigure back the old master, after a failover, - when it is reachable again, as the slave of the new master. This was due - to the inability to talk with the old master at all. - -2. BITFIELD bugs fixed. - -3. GEO commands fixes on syntax errors and edge cases. - -4. RESTORE now accepts dumps generated by older Redis versions. - -5. Jemalloc now is really configured to save you memory, for a problem a - change in the jemalloc configuration did not really survived when the - 3.2.0 release was finalized. - -6. TTL and TYPE command no longer alter the last access time of a key, for - LRU evictions purposes. A new TOUCH command was introduced *just* to - update the access time of a key. - -7. A bug was fixed in redis-cli, that connected to the instance running on the - port 6379 if there was one, regardless of what was specified. - -8. TCP keep alive is now enabled by default. This should fix most ghost - connections problems without resulting in any practical change in otherwise - sane deployments. - -9. A Sentinel crash that could happen during failovers was fixed. - -And of course, more minor things that you can read in the detailed log -below. There are still reported bugs for 3.2 that were not fixed in this -release, but nothing critical AFAIK, and I wanted to release this one ASAP, -so likely a new release will not be too far. - -Enjoy, -Salvatore - -+------------------------------------------------------------------------------- -| config set list-max-ziplist-size didn't support negative values, unlike config file -| By oranagra, 2016-05-22 20:35:14 +0300 -+-------------------------------------------------------------------------------- -https://github.com/antirez/redis/commit/8207e828043e37a0d7e058530d2886bb3ff395ff - - - src/config.c | 6 +++--- - 1 file changed, 3 insertions(+), 3 deletions(-) - -+------------------------------------------------------------------------------- -| Fix Sentinel pending commands counting. -| By antirez, 2016-06-16 19:24:34 +0200 -+-------------------------------------------------------------------------------- -https://github.com/antirez/redis/commit/6ad0371c9b4206a7a6692d50c9a301457baf9b6d - -This bug most experienced effect was an inability of Redis to -reconfigure back old masters to slaves after they are reachable again -after a failover.

And with the new release there is a new -format for the changelog. Now it is composed of a "letter" like the one -you are reading, followed by all the commits composing the release for people -interested in the details. - -There are a few changes between the latest release candidate of Redis 3.2 -and the final 3.2.0 release. The main ones are the obvious bug fixes you -can find detailed below, also a few new things: - -Critical bugs fixed: - -* There was a problem in the way a cluster instance loaded the AOF that - could cause data written via scripts to be lost during reshardings. - -New things: - -* There is a new very powerful BITFIELD command. Check the documentation - here: http://redis.io/commands/BITFIELD - -* CONFIG GET is allowed during the loading of the dataset. - -* The DEBUG command have new features and can show an help with DEBUG HELP. - -* redis-cli show hits about the commands arguments to the right. - -* GEORADIUS got a STORE / STOREDIST option to store the result into a target - key (as as orted set) instead of reporting it to the user. - -* Redis Cluster replicas migration now works in a slightly different way. In - the past a slave could migrate only to a master that used to have slaves - in the past (and if there was still trace of this information). Now instead - if a new slave gets at least a slot, and at least one other master in the - cluster has a slave, then the new master is considered a valid target for - replica migration. So if it will be orphaned and there is a spare slave - it will get one. - -* CLUSTER SLOTS output now includes the node ID (in a backward compatible - manner). - -* A lot of bug fixes you can read in the commits details below, with the - authors that kindly provided many useful patches. Thanks. - -As usually what "stable" means is that we are confident the release is mature, -however do your tests before putting it into production in your environemnt -as it's fresh meat anyway. - -Cheers, -Salvatore -

-The BITFIELD command supports subcommands that can SET, GET, or INCRBY -those arbitrary bit counters, with multiple overflow semantics. - -Trivial and credits: - -A similar command was imagined a few times in the past, but for -some reason looked a bit far fetched or not well specified. -Finally the command was proposed again in a clear form by -Yoav Steinberg from Redis Labs, that proposed a set of commands on -arbitrary sized integers stored at bit offsets. - -Starting from this proposal I wrote an initial specification of a single -command with sub-commands similar to what Yoav envisioned, using short -names for types definitions, and adding control on the overflow. -

Redis is a DSL (Domain Specific Language) - that manipulates abstract data types and implemented as a TCP daemon. - Commands manipulate a key space where keys are binary-safe strings and - values are different kinds of abstract data types. Every data type - represents an abstract version of a fundamental data structure. For instance - Redis Lists are an abstract representation of linked lists. In Redis, the - essence of a data type isn't just the kind of operations that the data types - support, but also the space and time complexity of the data type and the - operations performed upon it. - -2 - Memory storage is #1. The Redis data set, composed of defined key-value - pairs, is primarily stored in the computer's memory. The amount of memory in - all kinds of computers, including entry-level servers, is increasing - significantly each year. Memory is fast, and allows Redis to have very - predictable performance. Datasets composed of 10k or 40 millions keys will - perform similarly. Complex data types like Redis Sorted Sets are easy to - implement and manipulate in memory with good performance, making Redis very - simple. Redis will continue to explore alternative options (where data can - be optionally stored on disk, say) but the main goal of the project remains - the development of an in-memory database. - -3 - Fundamental data structures for a fundamental API. The Redis API is a direct - consequence of fundamental data structures. APIs can often be arbitrary but - not an API that resembles the nature of fundamental data structures. If we - ever meet intelligent life forms from another part of the universe, they'll - likely know, understand and recognize the same basic data structures we have - in our computer science books. Redis will avoid intermediate layers in API, - so that the complexity is obvious and more complex operations can be - performed as the sum of the basic operations. - -4 - Code is like a poem; it's not just something we write to reach some - practical result. Sometimes people that are far from the Redis philosophy - suggest using other code written by other authors (frequently in other - languages) in order to implement something Redis currently lacks. But to us - this is like if Shakespeare decided to end Enrico IV using the Paradiso from - the Divina Commedia. Is using any external code a bad idea? Not at all. Like - in "One Thousand and One Nights" smaller self contained stories are embedded - in a bigger story, we'll be happy to use beautiful self contained libraries - when needed. At the same time, when writing the Redis story we're trying to - write smaller stories that will fit in to other code. - -5 - We're against complexity. We believe designing systems is a fight against - complexity. We'll accept to fight the complexity when it's worthwhile but - we'll try hard to recognize when a small feature is not worth 1000s of lines - of code. Most of the time the best way to fight complexity is by not - creating it at all. - -6 - Two levels of API. The Redis API has two levels: 1) a subset of the API fits - naturally into a distributed version of Redis and 2) a more complex API that - supports multi-key operations. Both are useful if used judiciously but - there's no way to make the more complex multi-keys API distributed in an - opaque way without violating our other principles. We don't want to provide - the illusion of something that will work magically when actually it can't in - all cases. Instead we'll provide commands to quickly migrate keys from one - instance to another to perform multi-key operations and expose the tradeoffs - to the user. - -7 - We optimize for joy. We believe writing code is a lot of hard work, and the - only way it can be worth is by enjoying it. When there is no longer joy in - writing code, the best thing to do is stop. To prevent this, we'll avoid - taking paths that will make Redis less of a joy to develop. diff --git a/app/redis-3.2.8/Makefile b/app/redis-3.2.8/Makefile deleted file mode 100644 index e614ede8..00000000 --- a/app/redis-3.2.8/Makefile +++ /dev/null @@ -1,11 +0,0 @@ -# Top level makefile, the real shit is at src/Makefile - -default: all - -.DEFAULT: - cd src && $(MAKE) $@ - -install: - cd src && $(MAKE) $@ - -.PHONY: install diff --git a/app/redis-3.2.8/README.md b/app/redis-3.2.8/README.md deleted file mode 100644 index 5b3ca322..00000000 --- a/app/redis-3.2.8/README.md +++ /dev/null @@ -1,191 +0,0 @@ -This README is just a fast *quick start* document.

So different processes can query and modify the same data structures in a shared way. - -Data structures implemented into Redis have a few special properties: - -* Redis cares to store them on disk, even if they are always served and modified into the server memory. This means that Redis is fast, but that is also non-volatile. -* Implementation of data structures stress on memory efficiency, so data structures inside Redis will likely use less memory compared to the same data structure modeled using an high level programming language. -* Redis offers a number of features that are natural to find in a database, like replication, tunable levels of durability, cluster, high availability. - -Another good example is to think of Redis as a more complex version of memcached, where the operations are not just SETs and GETs, but operations to work with complex data types like Lists, Sets, ordered data structures, and so forth. - -If you want to know more, this is a list of selected starting points: - -* Introduction to Redis data types. http://redis.io/topics/data-types-intro -* Try Redis directly inside your browser. http://try.redis.io -* The full list of Redis commands. http://redis.io/commands -* There is much more inside the Redis official documentation. http://redis.io/documentation - -Building Redis --------------- - -Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD. -We support big endian and little endian architectures, and both 32 bit -and 64 bit systems. - -It may compile on Solaris derived systems (for instance SmartOS) but our -support for this platform is *best effort* and Redis is not guaranteed to -work as well as in Linux, OSX, and \*BSD there. - -It is as simple as: - - % make - -You can run a 32 bit Redis binary using: - - % make 32bit - -After building Redis is a good idea to test it, using: - - % make test - -Fixing build problems with dependencies or cached build options ---------- - -Redis has some dependencies which are included into the `deps` directory. -`make` does not rebuild dependencies automatically, even if something in the -source code of dependencies is changed. - -When you update the source code with `git pull` or when code inside the -dependencies tree is modified in any other way, make sure to use the following -command in order to really clean everything and rebuild from scratch: - - make distclean - -This will clean: jemalloc, lua, hiredis, linenoise. - -Also if you force certain build options like 32bit target, no C compiler -optimizations (for debugging purposes), and other similar build time options, -those options are cached indefinitely until you issue a `make distclean` -command. - -Fixing problems building 32 bit binaries ---------- - -If after building Redis with a 32 bit target you need to rebuild it -with a 64 bit target, or the other way around, you need to perform a -`make distclean` in the root directory of the Redis distribution. - -In case of build errors when trying to build a 32 bit binary of Redis, try -the following steps: - -* Install the packages libc6-dev-i386 (also try g++-multilib). -* Try using the following command line instead of `make 32bit`: - `make CFLAGS="-m32 -march=native" LDFLAGS="-m32"` - -Allocator ---------- - -Selecting a non-default memory allocator when building Redis is done by setting -the `MALLOC` environment variable.

Check with diff if hiredis API changed and what impact it could have in Redis. -2. Make sure thet the SDS library inside Hiredis and inside Redis are compatible. -3. After the upgrade, run the Redis Sentinel test. -4. Check manually that redis-cli and redis-benchmark behave as expecteed, since we have no tests for CLI utilities currently. - -Linenoise ---- - -Linenoise is rarely upgraded as needed. The upgrade process is trivial since -Redis uses a non modified version of linenoise, so to upgrade just do the -following: - -1. Remove the linenoise directory. -2. Substitute it with the new linenoise source tree. - -Lua ---- - -We use Lua 5.1 and no upgrade is planned currently, since we don't want to break -Lua scripts for new Lua features: in the context of Redis Lua scripts the -capabilities of 5.1 are usually more than enough, the release is rock solid, -and we definitely don't want to break old scripts. - -So upgrading of Lua is up to the Redis project maintainers and should be a -manual procedure performed by taking a diff between the different versions. - -Currently we have at least the following differences between official Lua 5.1 -and our version: - -1. Makefile is modified to allow a different compiler than GCC. -2. We have the implementation source code, and directly link to the following external libraries: `lua_cjson.o`, `lua_struct.o`, `lua_cmsgpack.o` and `lua_bit.o`. -3. There is a security fix in `ldo.c`, line 498: The check for `LUA_SIGNATURE[0]` is removed in order toa void direct bytecode exectuion. - - diff --git a/app/redis-3.2.8/deps/geohash-int/Makefile b/app/redis-3.2.8/deps/geohash-int/Makefile deleted file mode 100644 index b7c25957..00000000 --- a/app/redis-3.2.8/deps/geohash-int/Makefile +++ /dev/null @@ -1,23 +0,0 @@ -STD= -WARN= -Wall -OPT= -O2 - -R_CFLAGS= $(STD) $(WARN) $(OPT) $(DEBUG) $(CFLAGS) -R_LDFLAGS= $(LDFLAGS) -DEBUG= -g - -R_CC=$(CC) $(R_CFLAGS) -R_LD=$(CC) $(R_LDFLAGS) - -all: geohash.o geohash_helper.o - -.PHONY: all - -geohash.o: geohash.h geohash.c -geohash_helper.o: geohash.h geohash_helper.h geohash_helper.c - -.c.o: - $(R_CC) -c $< - -clean: - rm -f *.o diff --git a/app/redis-3.2.8/deps/geohash-int/geohash.c b/app/redis-3.2.8/deps/geohash-int/geohash.c deleted file mode 100644 index fb469445..00000000 --- a/app/redis-3.2.8/deps/geohash-int/geohash.c +++ /dev/null @@ -1,295 +0,0 @@ -/* - * Copyright (c) 2013-2014, yinqiwen - * Copyright (c) 2014, Matt Stancliff . - * Copyright (c) 2015-2016, Salvatore Sanfilippo . - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are met: - * - * * Redistributions of source code must retain the above copyright notice, - * this list of conditions and the following disclaimer. - * * Redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution. - * * Neither the name of Redis nor the names of its contributors may be used - * to endorse or promote products derived from this software without - * specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" - * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE - * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE - * ARE DISCLAIMED.

-# HIREDIS - -Hiredis is a minimalistic C client library for the [Redis](http://redis.io/) database. - -It is minimalistic because it just adds minimal support for the protocol, but -at the same time it uses an high level printf-alike API in order to make it -much higher level than otherwise suggested by its minimal code base and the -lack of explicit bindings for every Redis command. - -Apart from supporting sending commands and receiving replies, it comes with -a reply parser that is decoupled from the I/O layer. It -is a stream parser designed for easy reusability, which can for instance be used -in higher level language bindings for efficient reply parsing. - -Hiredis only supports the binary-safe Redis protocol, so you can use it with any -Redis version >= 1.2.0. - -The library comes with multiple APIs. There is the -*synchronous API*, the *asynchronous API* and the *reply parsing API*. - -## UPGRADING - -Version 0.9.0 is a major overhaul of hiredis in every aspect. However, upgrading existing -code using hiredis should not be a big pain. The key thing to keep in mind when -upgrading is that hiredis >= 0.9.0 uses a `redisContext*` to keep state, in contrast to -the stateless 0.0.1 that only has a file descriptor to work with. - -## Synchronous API - -To consume the synchronous API, there are only a few function calls that need to be introduced: - - redisContext *redisConnect(const char *ip, int port); - void *redisCommand(redisContext *c, const char *format, ...); - void freeReplyObject(void *reply); - -### Connecting - -The function `redisConnect` is used to create a so-called `redisContext`. The -context is where Hiredis holds state for a connection. The `redisContext` -struct has an integer `err` field that is non-zero when an the connection is in -an error state. The field `errstr` will contain a string with a description of -the error. More information on errors can be found in the **Errors** section. -After trying to connect to Redis using `redisConnect` you should -check the `err` field to see if establishing the connection was successful: - - redisContext *c = redisConnect("127.0.0.1", 6379); - if (c != NULL && c->err) { - printf("Error: %s\n", c->errstr); - // handle error - } - -### Sending commands - -There are several ways to issue commands to Redis. The first that will be introduced is -`redisCommand`. This function takes a format similar to printf. In the simplest form, -it is used like this: - - reply = redisCommand(context, "SET foo bar"); - -The specifier `%s` interpolates a string in the command, and uses `strlen` to -determine the length of the string: - - reply = redisCommand(context, "SET foo %s", value); - -When you need to pass binary safe strings in a command, the `%b` specifier can be -used. Together with a pointer to the string, it requires a `size_t` length argument -of the string: - - reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen); - -Internally, Hiredis splits the command in different arguments and will -convert it to the protocol used to communicate with Redis. -One or more spaces separates arguments, so you can use the specifiers -anywhere in an argument: - - reply = redisCommand(context, "SET key:%s %s", myid, value); - -### Using replies - -The return value of `redisCommand` holds a reply when the command was -successfully executed. When an error occurs, the return value is `NULL` and -the `err` field in the context will be set (see section on **Errors**). -Once an error is returned the context cannot be reused and you should set up -a new connection. - -The standard replies that `redisCommand` are of the type `redisReply`. The -`type` field in the `redisReply` should be used to test what kind of reply -was received: - -* **`REDIS_REPLY_STATUS`**: - * The command replied with a status reply. The status string can be accessed using `reply->str`. - The length of this string can be accessed using `reply->len`. - -* **`REDIS_REPLY_ERROR`**: - * The command replied with an error. The error string can be accessed identical to `REDIS_REPLY_STATUS`. - -* **`REDIS_REPLY_INTEGER`**: - * The command replied with an integer. The integer value can be accessed using the - `reply->integer` field of type `long long`. - -* **`REDIS_REPLY_NIL`**: - * The command replied with a **nil** object. There is no data to access. - -* **`REDIS_REPLY_STRING`**: - * A bulk (string) reply. The value of the reply can be accessed using `reply->str`. - The length of this string can be accessed using `reply->len`. - -* **`REDIS_REPLY_ARRAY`**: - * A multi bulk reply. The number of elements in the multi bulk reply is stored in - `reply->elements`. Every element in the multi bulk reply is a `redisReply` object as well - and can be accessed via `reply->element[..index..]`. - Redis may reply with nested arrays but this is fully supported. - -Replies should be freed using the `freeReplyObject()` function. -Note that this function will take care of freeing sub-replies objects -contained in arrays and nested arrays, so there is no need for the user to -free the sub replies (it is actually harmful and will corrupt the memory). - -**Important:** the current version of hiredis (0.10.0) free's replies when the -asynchronous API is used. This means you should not call `freeReplyObject` when -you use this API. The reply is cleaned up by hiredis _after_ the callback -returns. This behavior will probably change in future releases, so make sure to -keep an eye on the changelog when upgrading (see issue #39). - -### Cleaning up - -To disconnect and free the context the following function can be used: - - void redisFree(redisContext *c); - -This function immediately closes the socket and then free's the allocations done in -creating the context. - -### Sending commands (cont'd) - -Together with `redisCommand`, the function `redisCommandArgv` can be used to issue commands. -It has the following prototype: - - void *redisCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen); - -It takes the number of arguments `argc`, an array of strings `argv` and the lengths of the -arguments `argvlen`. For convenience, `argvlen` may be set to `NULL` and the function will -use `strlen(3)` on every argument to determine its length. Obviously, when any of the arguments -need to be binary safe, the entire array of lengths `argvlen` should be provided. - -The return value has the same semantic as `redisCommand`. - -### Pipelining - -To explain how Hiredis supports pipelining in a blocking connection, there needs to be -understanding of the internal execution flow. - -When any of the functions in the `redisCommand` family is called, Hiredis first formats the -command according to the Redis protocol. The formatted command is then put in the output buffer -of the context. This output buffer is dynamic, so it can hold any number of commands. -After the command is put in the output buffer, `redisGetReply` is called. This function has the -following two execution paths: - -1. The input buffer is non-empty: - * Try to parse a single reply from the input buffer and return it - * If no reply could be parsed, continue at *2* -2. The input buffer is empty: - * Write the **entire** output buffer to the socket - * Read from the socket until a single reply could be parsed - -The function `redisGetReply` is exported as part of the Hiredis API and can be used when a reply -is expected on the socket. To pipeline commands, the only things that needs to be done is -filling up the output buffer. For this cause, two commands can be used that are identical -to the `redisCommand` family, apart from not returning a reply: - - void redisAppendCommand(redisContext *c, const char *format, ...); - void redisAppendCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen); - -After calling either function one or more times, `redisGetReply` can be used to receive the -subsequent replies. The return value for this function is either `REDIS_OK` or `REDIS_ERR`, where -the latter means an error occurred while reading a reply. Just as with the other commands, -the `err` field in the context can be used to find out what the cause of this error is. - -The following examples shows a simple pipeline (resulting in only a single call to `write(2)` and -a single call to `read(2)`): - - redisReply *reply; - redisAppendCommand(context,"SET foo bar"); - redisAppendCommand(context,"GET foo"); - redisGetReply(context,&reply); // reply for SET - freeReplyObject(reply); - redisGetReply(context,&reply); // reply for GET - freeReplyObject(reply); - -This API can also be used to implement a blocking subscriber: - - reply = redisCommand(context,"SUBSCRIBE foo"); - freeReplyObject(reply); - while(redisGetReply(context,&reply) == REDIS_OK) { - // consume message - freeReplyObject(reply); - } - -### Errors - -When a function call is not successful, depending on the function either `NULL` or `REDIS_ERR` is -returned. The `err` field inside the context will be non-zero and set to one of the -following constants: - -* **`REDIS_ERR_IO`**: - There was an I/O error while creating the connection, trying to write - to the socket or read from the socket. If you included `errno.h` in your - application, you can use the global `errno` variable to find out what is - wrong. - -* **`REDIS_ERR_EOF`**: - The server closed the connection which resulted in an empty read. - -* **`REDIS_ERR_PROTOCOL`**: - There was an error while parsing the protocol. - -* **`REDIS_ERR_OTHER`**: - Any other error. Currently, it is only used when a specified hostname to connect - to cannot be resolved. - -In every case, the `errstr` field in the context will be set to hold a string representation -of the error. - -## Asynchronous API - -Hiredis comes with an asynchronous API that works easily with any event library. -Examples are bundled that show using Hiredis with [libev](http://software.schmorp.de/pkg/libev.html) -and [libevent](http://monkey.org/~provos/libevent/). - -### Connecting - -The function `redisAsyncConnect` can be used to establish a non-blocking connection to -Redis. It returns a pointer to the newly created `redisAsyncContext` struct. The `err` field -should be checked after creation to see if there were errors creating the connection. -Because the connection that will be created is non-blocking, the kernel is not able to -instantly return if the specified host and port is able to accept a connection. - - redisAsyncContext *c = redisAsyncConnect("127.0.0.1", 6379); - if (c->err) { - printf("Error: %s\n", c->errstr); - // handle error - } - -The asynchronous context can hold a disconnect callback function that is called when the -connection is disconnected (either because of an error or per user request). This function should -have the following prototype: - - void(const redisAsyncContext *c, int status); - -On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the -user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err` -field in the context can be accessed to find out the cause of the error. - -The context object is always free'd after the disconnect callback fired. When a reconnect is needed, -the disconnect callback is a good point to do so. - -Setting the disconnect callback can only be done once per context. For subsequent calls it will -return `REDIS_ERR`. The function to set the disconnect callback has the following prototype: - - int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn); - -### Sending commands and their callbacks - -In an asynchronous context, commands are automatically pipelined due to the nature of an event loop. -Therefore, unlike the synchronous API, there is only a single way to send commands. -Because commands are sent to Redis asynchronously, issuing a command requires a callback function -that is called when the reply is received. Reply callbacks should have the following prototype: - - void(redisAsyncContext *c, void *reply, void *privdata); - -The `privdata` argument can be used to curry arbitrary data to the callback from the point where -the command is initially queued for execution. - -The functions that can be used to issue commands in an asynchronous context are: - - int redisAsyncCommand( - redisAsyncContext *ac, redisCallbackFn *fn, void *privdata, - const char *format, ...); - int redisAsyncCommandArgv( - redisAsyncContext *ac, redisCallbackFn *fn, void *privdata, - int argc, const char **argv, const size_t *argvlen); - -Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command -was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection -is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is -returned on calls to the `redisAsyncCommand` family. - -If the reply for a command with a `NULL` callback is read, it is immediately free'd. When the callback -for a command is non-`NULL`, the memory is free'd immediately following the callback: the reply is only -valid for the duration of the callback. - -All pending callbacks are called with a `NULL` reply when the context encountered an error. - -### Disconnecting - -An asynchronous connection can be terminated using: - - void redisAsyncDisconnect(redisAsyncContext *ac); - -When this function is called, the connection is **not** immediately terminated. Instead, new -commands are no longer accepted and the connection is only terminated when all pending commands -have been written to the socket, their respective replies have been read and their respective -callbacks have been executed. After this, the disconnection callback is executed with the -`REDIS_OK` status and the context object is free'd. - -### Hooking it up to event library *X* - -There are a few hooks that need to be set on the context object after it is created. -See the `adapters/` directory for bindings to *libev* and *libevent*. - -## Reply parsing API - -Hiredis comes with a reply parsing API that makes it easy for writing higher -level language bindings. - -The reply parsing API consists of the following functions: - - redisReader *redisReaderCreate(void); - void redisReaderFree(redisReader *reader); - int redisReaderFeed(redisReader *reader, const char *buf, size_t len); - int redisReaderGetReply(redisReader *reader, void **reply); - -The same set of functions are used internally by hiredis when creating a -normal Redis context, the above API just exposes it to the user for a direct -usage. - -### Usage - -The function `redisReaderCreate` creates a `redisReader` structure that holds a -buffer with unparsed data and state for the protocol parser. - -Incoming data -- most likely from a socket -- can be placed in the internal -buffer of the `redisReader` using `redisReaderFeed`. This function will make a -copy of the buffer pointed to by `buf` for `len` bytes. This data is parsed -when `redisReaderGetReply` is called. This function returns an integer status -and a reply object (as described above) via `void **reply`. The returned status -can be either `REDIS_OK` or `REDIS_ERR`, where the latter means something went -wrong (either a protocol error, or an out of memory error). - -The parser limits the level of nesting for multi bulk payloads to 7. If the -multi bulk nesting level is higher than this, the parser returns an error. - -### Customizing replies - -The function `redisReaderGetReply` creates `redisReply` and makes the function -argument `reply` point to the created `redisReply` variable. For instance, if -the response of type `REDIS_REPLY_STATUS` then the `str` field of `redisReply` -will hold the status as a vanilla C string. However, the functions that are -responsible for creating instances of the `redisReply` can be customized by -setting the `fn` field on the `redisReader` struct. This should be done -immediately after creating the `redisReader`. - -For example, [hiredis-rb](https://github.com/pietern/hiredis-rb/blob/master/ext/hiredis_ext/reader.c) -uses customized reply object functions to create Ruby objects. - -### Reader max buffer - -Both when using the Reader API directly or when using it indirectly via a -normal Redis context, the redisReader structure uses a buffer in order to -accumulate data from the server. -Usually this buffer is destroyed when it is empty and is larger than 16 -kb in order to avoid wasting memory in unused buffers - -However when working with very big payloads destroying the buffer may slow -down performances considerably, so it is possible to modify the max size of -an idle buffer changing the value of the `maxbuf` field of the reader structure -to the desired value. The special value of 0 means that there is no maximum -value for an idle buffer, so the buffer will never get freed. - -For instance if you have a normal Redis context you can set the maximum idle -buffer to zero (unlimited) just with: - - context->reader->maxbuf = 0; - -This should be done only in order to maximize performances when working with -large payloads. The context should be set back to `REDIS_READER_MAX_BUF` again -as soon as possible in order to prevent allocation of useless memory. - -## AUTHORS - -Hiredis was written by Salvatore Sanfilippo (antirez at gmail) and -Pieter Noordhuis (pcnoordhuis at gmail) and is released under the BSD license. diff --git a/app/redis-3.2.8/deps/hiredis/adapters/ae.h b/app/redis-3.2.8/deps/hiredis/adapters/ae.h deleted file mode 100644 index 5c551c2e..00000000 --- a/app/redis-3.2.8/deps/hiredis/adapters/ae.h +++ /dev/null @@ -1,127 +0,0 @@ -/* - * Copyright (c) 2010-2011, Pieter Noordhuis - * - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are met: - * - * * Redistributions of source code must retain the above copyright notice, - * this list of conditions and the following disclaimer. - * * Redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution. - * * Neither the name of Redis nor the names of its contributors may be used - * to endorse or promote products derived from this software without - * specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" - * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE - * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE - * ARE DISCLAIMED.

Note that a couple of minor heap profiling - optimizations are included, but these are better thought of as performance - fixes that were integral to disovering most of the other bugs. - - Optimizations: - - Avoid a chunk metadata read in arena_prof_tctx_set(), since it is in the - fast path when heap profiling is enabled. Additionally, split a special - case out into arena_prof_tctx_reset(), which also avoids chunk metadata - reads. - - Optimize irallocx_prof() to optimistically update the sampler state. The - prior implementation appears to have been a holdover from when - rallocx()/xallocx() functionality was combined as rallocm(). - - Bug fixes: - - Fix TLS configuration such that it is enabled by default for platforms on - which it works correctly. - - Fix arenas_cache_cleanup() and arena_get_hard() to handle - allocation/deallocation within the application's thread-specific data - cleanup functions even after arenas_cache is torn down. - - Fix xallocx() bugs related to size+extra exceeding HUGE_MAXCLASS. - - Fix chunk purge hook calls for in-place huge shrinking reallocation to - specify the old chunk size rather than the new chunk size. This bug caused - no correctness issues for the default chunk purge function, but was - visible to custom functions set via the "arena..chunk_hooks" mallctl. - - Fix heap profiling bugs: - + Fix heap profiling to distinguish among otherwise identical sample sites - with interposed resets (triggered via the "prof.reset" mallctl). This bug - could cause data structure corruption that would most likely result in a - segfault. - + Fix irealloc_prof() to prof_alloc_rollback() on OOM. - + Make one call to prof_active_get_unlocked() per allocation event, and use - the result throughout the relevant functions that handle an allocation - event. Also add a missing check in prof_realloc(). These fixes protect - allocation events against concurrent prof_active changes. - + Fix ixallocx_prof() to pass usize_max and zero to ixallocx_prof_sample() - in the correct order. - + Fix prof_realloc() to call prof_free_sampled_object() after calling - prof_malloc_sample_object(). Prior to this fix, if tctx and old_tctx were - the same, the tctx could have been prematurely destroyed. - - Fix portability bugs: - + Don't bitshift by negative amounts when encoding/decoding run sizes in - chunk header maps. This affected systems with page sizes greater than 8 - KiB. - + Rename index_t to szind_t to avoid an existing type on Solaris. - + Add JEMALLOC_CXX_THROW to the memalign() function prototype, in order to - match glibc and avoid compilation errors when including both - jemalloc/jemalloc.h and malloc.h in C++ code. - + Don't assume that /bin/sh is appropriate when running size_classes.sh - during configuration. - + Consider __sparcv9 a synonym for __sparc64__ when defining LG_QUANTUM. - + Link tests to librt if it contains clock_gettime(2). - -* 4.0.0 (August 17, 2015) - - This version contains many speed and space optimizations, both minor and - major. The major themes are generalization, unification, and simplification. - Although many of these optimizations cause no visible behavior change, their - cumulative effect is substantial. - - New features: - - Normalize size class spacing to be consistent across the complete size - range. By default there are four size classes per size doubling, but this - is now configurable via the --with-lg-size-class-group option. Also add the - --with-lg-page, --with-lg-page-sizes, --with-lg-quantum, and - --with-lg-tiny-min options, which can be used to tweak page and size class - settings. Impacts: - + Worst case performance for incrementally growing/shrinking reallocation - is improved because there are far fewer size classes, and therefore - copying happens less often. - + Internal fragmentation is limited to 20% for all but the smallest size - classes (those less than four times the quantum). (1B + 4 KiB) - and (1B + 4 MiB) previously suffered nearly 50% internal fragmentation. - + Chunk fragmentation tends to be lower because there are fewer distinct run - sizes to pack. - - Add support for explicit tcaches. The "tcache.create", "tcache.flush", and - "tcache.destroy" mallctls control tcache lifetime and flushing, and the - MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to the *allocx() API - control which tcache is used for each operation. - - Implement per thread heap profiling, as well as the ability to - enable/disable heap profiling on a per thread basis. Add the "prof.reset", - "prof.lg_sample", "thread.prof.name", "thread.prof.active", - "opt.prof_thread_active_init", "prof.thread_active_init", and - "thread.prof.active" mallctls. - - Add support for per arena application-specified chunk allocators, configured - via the "arena..chunk_hooks" mallctl. - - Refactor huge allocation to be managed by arenas, so that arenas now - function as general purpose independent allocators. This is important in - the context of user-specified chunk allocators, aside from the scalability - benefits. Related new statistics: - + The "stats.arenas..huge.allocated", "stats.arenas..huge.nmalloc", - "stats.arenas..huge.ndalloc", and "stats.arenas..huge.nrequests" - mallctls provide high level per arena huge allocation statistics. - + The "arenas.nhchunks", "arenas.hchunk..size", - "stats.arenas..hchunks..nmalloc", - "stats.arenas..hchunks..ndalloc", - "stats.arenas..hchunks..nrequests", and - "stats.arenas..hchunks..curhchunks" mallctls provide per size class - statistics. - - Add the 'util' column to malloc_stats_print() output, which reports the - proportion of available regions that are currently in use for each small - size class. - - Add "alloc" and "free" modes for for junk filling (see the "opt.junk" - mallctl), so that it is possible to separately enable junk filling for - allocation versus deallocation. - - Add the jemalloc-config script, which provides information about how - jemalloc was configured, and how to integrate it into application builds. - - Add metadata statistics, which are accessible via the "stats.metadata", - "stats.arenas..metadata.mapped", and - "stats.arenas..metadata.allocated" mallctls. - - Add the "stats.resident" mallctl, which reports the upper limit of - physically resident memory mapped by the allocator. - - Add per arena control over unused dirty page purging, via the - "arenas.lg_dirty_mult", "arena..lg_dirty_mult", and - "stats.arenas..lg_dirty_mult" mallctls. - - Add the "prof.gdump" mallctl, which makes it possible to toggle the gdump - feature on/off during program execution. - - Add sdallocx(), which implements sized deallocation. The primary - optimization over dallocx() is the removal of a metadata read, which often - suffers an L1 cache miss. - - Add missing header includes in jemalloc/jemalloc.h, so that applications - only have to #include . - - Add support for additional platforms: - + Bitrig - + Cygwin - + DragonFlyBSD - + iOS - + OpenBSD - + OpenRISC/or1k - - Optimizations: - - Maintain dirty runs in per arena LRUs rather than in per arena trees of - dirty-run-containing chunks. In practice this change significantly reduces - dirty page purging volume. - - Integrate whole chunks into the unused dirty page purging machinery. This - reduces the cost of repeated huge allocation/deallocation, because it - effectively introduces a cache of chunks. - - Split the arena chunk map into two separate arrays, in order to increase - cache locality for the frequently accessed bits. - - Move small run metadata out of runs, into arena chunk headers. This reduces - run fragmentation, smaller runs reduce external fragmentation for small size - classes, and packed (less uniformly aligned) metadata layout improves CPU - cache set distribution. - - Randomly distribute large allocation base pointer alignment relative to page - boundaries in order to more uniformly utilize CPU cache sets. This can be - disabled via the --disable-cache-oblivious configure option, and queried via - the "config.cache_oblivious" mallctl. - - Micro-optimize the fast paths for the public API functions. - - Refactor thread-specific data to reside in a single structure. This assures - that only a single TLS read is necessary per call into the public API. - - Implement in-place huge allocation growing and shrinking. - - Refactor rtree (radix tree for chunk lookups) to be lock-free, and make - additional optimizations that reduce maximum lookup depth to one or two - levels. This resolves what was a concurrency bottleneck for per arena huge - allocation, because a global data structure is critical for determining - which arenas own which huge allocations. - - Incompatible changes: - - Replace --enable-cc-silence with --disable-cc-silence to suppress spurious - warnings by default. - - Assure that the constness of malloc_usable_size()'s return type matches that - of the system implementation. - - Change the heap profile dump format to support per thread heap profiling, - rename pprof to jeprof, and enhance it with the --thread= option. As a - result, the bundled jeprof must now be used rather than the upstream - (gperftools) pprof. - - Disable "opt.prof_final" by default, in order to avoid atexit(3), which can - internally deadlock on some platforms. - - Change the "arenas.nlruns" mallctl type from size_t to unsigned. - - Replace the "stats.arenas..bins..allocated" mallctl with - "stats.arenas..bins..curregs". - - Ignore MALLOC_CONF in set{uid,gid,cap} binaries. - - Ignore MALLOCX_ARENA(a) in dallocx(), in favor of using the - MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to control tcache usage. - - Removed features: - - Remove the *allocm() API, which is superseded by the *allocx() API. - - Remove the --enable-dss options, and make dss non-optional on all platforms - which support sbrk(2). - - Remove the "arenas.purge" mallctl, which was obsoleted by the - "arena..purge" mallctl in 3.1.0. - - Remove the unnecessary "opt.valgrind" mallctl; jemalloc automatically - detects whether it is running inside Valgrind. - - Remove the "stats.huge.allocated", "stats.huge.nmalloc", and - "stats.huge.ndalloc" mallctls. - - Remove the --enable-mremap option. - - Remove the "stats.chunks.current", "stats.chunks.total", and - "stats.chunks.high" mallctls. - - Bug fixes: - - Fix the cactive statistic to decrease (rather than increase) when active - memory decreases. This regression was first released in 3.5.0. - - Fix OOM handling in memalign() and valloc(). A variant of this bug existed - in all releases since 2.0.0, which introduced these functions. - - Fix an OOM-related regression in arena_tcache_fill_small(), which could - cause cache corruption on OOM. This regression was present in all releases - from 2.2.0 through 3.6.0. - - Fix size class overflow handling for malloc(), posix_memalign(), memalign(), - calloc(), and realloc() when profiling is enabled. - - Fix the "arena..dss" mallctl to return an error if "primary" or - "secondary" precedence is specified, but sbrk(2) is not supported. - - Fix fallback lg_floor() implementations to handle extremely large inputs. - - Ensure the default purgeable zone is after the default zone on OS X. - - Fix latent bugs in atomic_*(). - - Fix the "arena..dss" mallctl to handle read-only calls. - - Fix tls_model configuration to enable the initial-exec model when possible. - - Mark malloc_conf as a weak symbol so that the application can override it. - - Correctly detect glibc's adaptive pthread mutexes. - - Fix the --without-export configure option. - -* 3.6.0 (March 31, 2014) - - This version contains a critical bug fix for a regression present in 3.5.0 and - 3.5.1. - - Bug fixes: - - Fix a regression in arena_chunk_alloc() that caused crashes during - small/large allocation if chunk allocation failed. In the absence of this - bug, chunk allocation failure would result in allocation failure, e.g. NULL - return from malloc(). This regression was introduced in 3.5.0. - - Fix backtracing for gcc intrinsics-based backtracing by specifying - -fno-omit-frame-pointer to gcc. Note that the application (and all the - libraries it links to) must also be compiled with this option for - backtracing to be reliable. - - Use dss allocation precedence for huge allocations as well as small/large - allocations. - - Fix test assertion failure message formatting. This bug did not manifest on - x86_64 systems because of implementation subtleties in va_list. - - Fix inconsequential test failures for hash and SFMT code. - - New features: - - Support heap profiling on FreeBSD. This feature depends on the proc - filesystem being mounted during heap profile dumping. - -* 3.5.1 (February 25, 2014) - - This version primarily addresses minor bugs in test code. - - Bug fixes: - - Configure Solaris/Illumos to use MADV_FREE. - - Fix junk filling for mremap(2)-based huge reallocation. This is only - relevant if configuring with the --enable-mremap option specified. - - Avoid compilation failure if 'restrict' C99 keyword is not supported by the - compiler. - - Add a configure test for SSE2 rather than assuming it is usable on i686 - systems. This fixes test compilation errors, especially on 32-bit Linux - systems. - - Fix mallctl argument size mismatches (size_t vs. uint64_t) in the stats unit - test. - - Fix/remove flawed alignment-related overflow tests. - - Prevent compiler optimizations that could change backtraces in the - prof_accum unit test. - -* 3.5.0 (January 22, 2014) - - This version focuses on refactoring and automated testing, though it also - includes some non-trivial heap profiling optimizations not mentioned below. - - New features: - - Add the *allocx() API, which is a successor to the experimental *allocm() - API. The *allocx() functions are slightly simpler to use because they have - fewer parameters, they directly return the results of primary interest, and - mallocx()/rallocx() avoid the strict aliasing pitfall that - allocm()/rallocm() share with posix_memalign(). Note that *allocm() is - slated for removal in the next non-bugfix release. - - Add support for LinuxThreads. - - Bug fixes: - - Unless heap profiling is enabled, disable floating point code and don't link - with libm. This, in combination with e.g. EXTRA_CFLAGS=-mno-sse on x64 - systems, makes it possible to completely disable floating point register - use. Some versions of glibc neglect to save/restore caller-saved floating - point registers during dynamic lazy symbol loading, and the symbol loading - code uses whatever malloc the application happens to have linked/loaded - with, the result being potential floating point register corruption. - - Report ENOMEM rather than EINVAL if an OOM occurs during heap profiling - backtrace creation in imemalign(). This bug impacted posix_memalign() and - aligned_alloc(). - - Fix a file descriptor leak in a prof_dump_maps() error path. - - Fix prof_dump() to close the dump file descriptor for all relevant error - paths. - - Fix rallocm() to use the arena specified by the ALLOCM_ARENA(s) flag for - allocation, not just deallocation. - - Fix a data race for large allocation stats counters. - - Fix a potential infinite loop during thread exit. This bug occurred on - Solaris, and could affect other platforms with similar pthreads TSD - implementations. - - Don't junk-fill reallocations unless usable size changes. This fixes a - violation of the *allocx()/*allocm() semantics. - - Fix growing large reallocation to junk fill new space. - - Fix huge deallocation to junk fill when munmap is disabled. - - Change the default private namespace prefix from empty to je_, and change - --with-private-namespace-prefix so that it prepends an additional prefix - rather than replacing je_. This reduces the likelihood of applications - which statically link jemalloc experiencing symbol name collisions. - - Add missing private namespace mangling (relevant when - --with-private-namespace is specified). - - Add and use JEMALLOC_INLINE_C so that static inline functions are marked as - static even for debug builds. - - Add a missing mutex unlock in a malloc_init_hard() error path. In practice - this error path is never executed. - - Fix numerous bugs in malloc_strotumax() error handling/reporting. These - bugs had no impact except for malformed inputs. - - Fix numerous bugs in malloc_snprintf(). These bugs were not exercised by - existing calls, so they had no impact. - -* 3.4.1 (October 20, 2013) - - Bug fixes: - - Fix a race in the "arenas.extend" mallctl that could cause memory corruption - of internal data structures and subsequent crashes. - - Fix Valgrind integration flaws that caused Valgrind warnings about reads of - uninitialized memory in: - + arena chunk headers - + internal zero-initialized data structures (relevant to tcache and prof - code) - - Preserve errno during the first allocation. A readlink(2) call during - initialization fails unless /etc/malloc.conf exists, so errno was typically - set during the first allocation prior to this fix. - - Fix compilation warnings reported by gcc 4.8.1. - -* 3.4.0 (June 2, 2013) - - This version is essentially a small bugfix release, but the addition of - aarch64 support requires that the minor version be incremented. - - Bug fixes: - - Fix race-triggered deadlocks in chunk_record(). These deadlocks were - typically triggered by multiple threads concurrently deallocating huge - objects. - - New features: - - Add support for the aarch64 architecture. - -* 3.3.1 (March 6, 2013) - - This version fixes bugs that are typically encountered only when utilizing - custom run-time options. - - Bug fixes: - - Fix a locking order bug that could cause deadlock during fork if heap - profiling were enabled. - - Fix a chunk recycling bug that could cause the allocator to lose track of - whether a chunk was zeroed. On FreeBSD, NetBSD, and OS X, it could cause - corruption if allocating via sbrk(2) (unlikely unless running with the - "dss:primary" option specified). This was completely harmless on Linux - unless using mlockall(2) (and unlikely even then, unless the - --disable-munmap configure option or the "dss:primary" option was - specified). This regression was introduced in 3.1.0 by the - mlockall(2)/madvise(2) interaction fix. - - Fix TLS-related memory corruption that could occur during thread exit if the - thread never allocated memory. Only the quarantine and prof facilities were - susceptible. - - Fix two quarantine bugs: - + Internal reallocation of the quarantined object array leaked the old - array. - + Reallocation failure for internal reallocation of the quarantined object - array (very unlikely) resulted in memory corruption. - - Fix Valgrind integration to annotate all internally allocated memory in a - way that keeps Valgrind happy about internal data structure access. - - Fix building for s390 systems. - -* 3.3.0 (January 23, 2013) - - This version includes a few minor performance improvements in addition to the - listed new features and bug fixes. - - New features: - - Add clipping support to lg_chunk option processing. - - Add the --enable-ivsalloc option. - - Add the --without-export option. - - Add the --disable-zone-allocator option. - - Bug fixes: - - Fix "arenas.extend" mallctl to output the number of arenas. - - Fix chunk_recycle() to unconditionally inform Valgrind that returned memory - is undefined. - - Fix build break on FreeBSD related to alloca.h. - -* 3.2.0 (November 9, 2012) - - In addition to a couple of bug fixes, this version modifies page run - allocation and dirty page purging algorithms in order to better control - page-level virtual memory fragmentation. - - Incompatible changes: - - Change the "opt.lg_dirty_mult" default from 5 to 3 (32:1 to 8:1). - - Bug fixes: - - Fix dss/mmap allocation precedence code to use recyclable mmap memory only - after primary dss allocation fails. - - Fix deadlock in the "arenas.purge" mallctl. This regression was introduced - in 3.1.0 by the addition of the "arena..purge" mallctl. - -* 3.1.0 (October 16, 2012) - - New features: - - Auto-detect whether running inside Valgrind, thus removing the need to - manually specify MALLOC_CONF=valgrind:true. - - Add the "arenas.extend" mallctl, which allows applications to create - manually managed arenas. - - Add the ALLOCM_ARENA() flag for {,r,d}allocm(). - - Add the "opt.dss", "arena..dss", and "stats.arenas..dss" mallctls, - which provide control over dss/mmap precedence. - - Add the "arena..purge" mallctl, which obsoletes "arenas.purge". - - Define LG_QUANTUM for hppa. - - Incompatible changes: - - Disable tcache by default if running inside Valgrind, in order to avoid - making unallocated objects appear reachable to Valgrind. - - Drop const from malloc_usable_size() argument on Linux. - - Bug fixes: - - Fix heap profiling crash if sampled object is freed via realloc(p, 0). - - Remove const from __*_hook variable declarations, so that glibc can modify - them during process forking. - - Fix mlockall(2)/madvise(2) interaction. - - Fix fork(2)-related deadlocks. - - Fix error return value for "thread.tcache.enabled" mallctl. - -* 3.0.0 (May 11, 2012) - - Although this version adds some major new features, the primary focus is on - internal code cleanup that facilitates maintainability and portability, most - of which is not reflected in the ChangeLog. This is the first release to - incorporate substantial contributions from numerous other developers, and the - result is a more broadly useful allocator (see the git revision history for - contribution details). Note that the license has been unified, thanks to - Facebook granting a license under the same terms as the other copyright - holders (see COPYING). - - New features: - - Implement Valgrind support, redzones, and quarantine. - - Add support for additional platforms: - + FreeBSD - + Mac OS X Lion - + MinGW - + Windows (no support yet for replacing the system malloc) - - Add support for additional architectures: - + MIPS - + SH4 - + Tilera - - Add support for cross compiling. - - Add nallocm(), which rounds a request size up to the nearest size class - without actually allocating. - - Implement aligned_alloc() (blame C11). - - Add the "thread.tcache.enabled" mallctl. - - Add the "opt.prof_final" mallctl. - - Update pprof (from gperftools 2.0). - - Add the --with-mangling option. - - Add the --disable-experimental option. - - Add the --disable-munmap option, and make it the default on Linux. - - Add the --enable-mremap option, which disables use of mremap(2) by default. - - Incompatible changes: - - Enable stats by default. - - Enable fill by default. - - Disable lazy locking by default. - - Rename the "tcache.flush" mallctl to "thread.tcache.flush". - - Rename the "arenas.pagesize" mallctl to "arenas.page". - - Change the "opt.lg_prof_sample" default from 0 to 19 (1 B to 512 KiB). - - Change the "opt.prof_accum" default from true to false. - - Removed features: - - Remove the swap feature, including the "config.swap", "swap.avail", - "swap.prezeroed", "swap.nfds", and "swap.fds" mallctls. - - Remove highruns statistics, including the - "stats.arenas..bins..highruns" and - "stats.arenas..lruns..highruns" mallctls. - - As part of small size class refactoring, remove the "opt.lg_[qc]space_max", - "arenas.cacheline", "arenas.subpage", "arenas.[tqcs]space_{min,max}", and - "arenas.[tqcs]bins" mallctls. - - Remove the "arenas.chunksize" mallctl. - - Remove the "opt.lg_prof_tcmax" option. - - Remove the "opt.lg_prof_bt_max" option. - - Remove the "opt.lg_tcache_gc_sweep" option. - - Remove the --disable-tiny option, including the "config.tiny" mallctl. - - Remove the --enable-dynamic-page-shift configure option. - - Remove the --enable-sysv configure option. - - Bug fixes: - - Fix a statistics-related bug in the "thread.arena" mallctl that could cause - invalid statistics and crashes. - - Work around TLS deallocation via free() on Linux. This bug could cause - write-after-free memory corruption. - - Fix a potential deadlock that could occur during interval- and - growth-triggered heap profile dumps. - - Fix large calloc() zeroing bugs due to dropping chunk map unzeroed flags. - - Fix chunk_alloc_dss() to stop claiming memory is zeroed. This bug could - cause memory corruption and crashes with --enable-dss specified. - - Fix fork-related bugs that could cause deadlock in children between fork - and exec. - - Fix malloc_stats_print() to honor 'b' and 'l' in the opts parameter. - - Fix realloc(p, 0) to act like free(p). - - Do not enforce minimum alignment in memalign(). - - Check for NULL pointer in malloc_usable_size(). - - Fix an off-by-one heap profile statistics bug that could be observed in - interval- and growth-triggered heap profiles. - - Fix the "epoch" mallctl to update cached stats even if the passed in epoch - is 0. - - Fix bin->runcur management to fix a layout policy bug. This bug did not - affect correctness. - - Fix a bug in choose_arena_hard() that potentially caused more arenas to be - initialized than necessary. - - Add missing "opt.lg_tcache_max" mallctl implementation. - - Use glibc allocator hooks to make mixed allocator usage less likely. - - Fix build issues for --disable-tcache. - - Don't mangle pthread_create() when --with-private-namespace is specified. - -* 2.2.5 (November 14, 2011) - - Bug fixes: - - Fix huge_ralloc() race when using mremap(2). This is a serious bug that - could cause memory corruption and/or crashes. - - Fix huge_ralloc() to maintain chunk statistics. - - Fix malloc_stats_print(..., "a") output. - -* 2.2.4 (November 5, 2011) - - Bug fixes: - - Initialize arenas_tsd before using it. This bug existed for 2.2.[0-3], as - well as for --disable-tls builds in earlier releases. - - Do not assume a 4 KiB page size in test/rallocm.c. - -* 2.2.3 (August 31, 2011) - - This version fixes numerous bugs related to heap profiling. - - Bug fixes: - - Fix a prof-related race condition. This bug could cause memory corruption, - but only occurred in non-default configurations (prof_accum:false). - - Fix off-by-one backtracing issues (make sure that prof_alloc_prep() is - excluded from backtraces). - - Fix a prof-related bug in realloc() (only triggered by OOM errors). - - Fix prof-related bugs in allocm() and rallocm(). - - Fix prof_tdata_cleanup() for --disable-tls builds. - - Fix a relative include path, to fix objdir builds. - -* 2.2.2 (July 30, 2011) - - Bug fixes: - - Fix a build error for --disable-tcache. - - Fix assertions in arena_purge() (for real this time). - - Add the --with-private-namespace option. This is a workaround for symbol - conflicts that can inadvertently arise when using static libraries. - -* 2.2.1 (March 30, 2011) - - Bug fixes: - - Implement atomic operations for x86/x64.

Nonetheless, numerous performance - improvements are also included. - - New features: - - Implement the experimental {,r,s,d}allocm() API, which provides a superset - of the functionality available via malloc(), calloc(), posix_memalign(), - realloc(), malloc_usable_size(), and free(). These functions can be used to - allocate/reallocate aligned zeroed memory, ask for optional extra memory - during reallocation, prevent object movement during reallocation, etc. - - Replace JEMALLOC_OPTIONS/JEMALLOC_PROF_PREFIX with MALLOC_CONF, which is - more human-readable, and more flexible. For example: - JEMALLOC_OPTIONS=AJP - is now: - MALLOC_CONF=abort:true,fill:true,stats_print:true - - Port to Apple OS X. Sponsored by Mozilla. - - Make it possible for the application to control thread-->arena mappings via - the "thread.arena" mallctl. - - Add compile-time support for all TLS-related functionality via pthreads TSD. - This is mainly of interest for OS X, which does not support TLS, but has a - TSD implementation with similar performance. - - Override memalign() and valloc() if they are provided by the system. - - Add the "arenas.purge" mallctl, which can be used to synchronously purge all - dirty unused pages. - - Make cumulative heap profiling data optional, so that it is possible to - limit the amount of memory consumed by heap profiling data structures. - - Add per thread allocation counters that can be accessed via the - "thread.allocated" and "thread.deallocated" mallctls. - - Incompatible changes: - - Remove JEMALLOC_OPTIONS and malloc_options (see MALLOC_CONF above). - - Increase default backtrace depth from 4 to 128 for heap profiling. - - Disable interval-based profile dumps by default. - - Bug fixes: - - Remove bad assertions in fork handler functions. These assertions could - cause aborts for some combinations of configure settings. - - Fix strerror_r() usage to deal with non-standard semantics in GNU libc. - - Fix leak context reporting. This bug tended to cause the number of contexts - to be underreported (though the reported number of objects and bytes were - correct). - - Fix a realloc() bug for large in-place growing reallocation. This bug could - cause memory corruption, but it was hard to trigger. - - Fix an allocation bug for small allocations that could be triggered if - multiple threads raced to create a new run of backing pages. - - Enhance the heap profiler to trigger samples based on usable size, rather - than request size. - - Fix a heap profiling bug due to sometimes losing track of requested object - size for sampled objects. - -* 1.0.3 (August 12, 2010) - - Bug fixes: - - Fix the libunwind-based implementation of stack backtracing (used for heap - profiling). This bug could cause zero-length backtraces to be reported. - - Add a missing mutex unlock in library initialization code. If multiple - threads raced to initialize malloc, some of them could end up permanently - blocked. - -* 1.0.2 (May 11, 2010) - - Bug fixes: - - Fix junk filling of large objects, which could cause memory corruption. - - Add MAP_NORESERVE support for chunk mapping, because otherwise virtual - memory limits could cause swap file configuration to fail. Contributed by - Jordan DeLong. - -* 1.0.1 (April 14, 2010) - - Bug fixes: - - Fix compilation when --enable-fill is specified. - - Fix threads-related profiling bugs that affected accuracy and caused memory - to be leaked during thread exit. - - Fix dirty page purging race conditions that could cause crashes. - - Fix crash in tcache flushing code during thread destruction. - -* 1.0.0 (April 11, 2010) - - This release focuses on speed and run-time introspection. Numerous - algorithmic improvements make this release substantially faster than its - predecessors. - - New features: - - Implement autoconf-based configuration system. - - Add mallctl*(), for the purposes of introspection and run-time - configuration. - - Make it possible for the application to manually flush a thread's cache, via - the "tcache.flush" mallctl. - - Base maximum dirty page count on proportion of active memory. - - Compute various additional run-time statistics, including per size class - statistics for large objects. - - Expose malloc_stats_print(), which can be called repeatedly by the - application. - - Simplify the malloc_message() signature to only take one string argument, - and incorporate an opaque data pointer argument for use by the application - in combination with malloc_stats_print(). - - Add support for allocation backed by one or more swap files, and allow the - application to disable over-commit if swap files are in use. - - Implement allocation profiling and leak checking. - - Removed features: - - Remove the dynamic arena rebalancing code, since thread-specific caching - reduces its utility. - - Bug fixes: - - Modify chunk allocation to work when address space layout randomization - (ASLR) is in use. - - Fix thread cleanup bugs related to TLS destruction. - - Handle 0-size allocation requests in posix_memalign(). - - Fix a chunk leak. The leaked chunks were never touched, so this impacted - virtual memory usage, but not physical memory usage. - -* linux_2008082[78]a (August 27/28, 2008) - - These snapshot releases are the simple result of incorporating Linux-specific - support into the FreeBSD malloc sources. - --------------------------------------------------------------------------------- -vim:filetype=text:textwidth=80 diff --git a/app/redis-3.2.8/deps/jemalloc/INSTALL b/app/redis-3.2.8/deps/jemalloc/INSTALL deleted file mode 100644 index 8d396874..00000000 --- a/app/redis-3.2.8/deps/jemalloc/INSTALL +++ /dev/null @@ -1,402 +0,0 @@ -Building and installing a packaged release of jemalloc can be as simple as -typing the following while in the root directory of the source tree: - - ./configure - make - make install - -If building from unpackaged developer sources, the simplest command sequence -that might work is: - - ./autogen.sh - make dist - make - make install - -Note that documentation is not built by the default target because doing so -would create a dependency on xsltproc in packaged releases, hence the -requirement to either run 'make dist' or avoid installing docs via the various -install_* targets documented below. - -=== Advanced configuration ===================================================== - -The 'configure' script supports numerous options that allow control of which -functionality is enabled, where jemalloc is installed, etc. Optionally, pass -any of the following arguments (not a definitive list) to 'configure': - ---help - Print a definitive list of options. - ---prefix= - Set the base directory in which to install.

If this feature is disabled, all - large allocations are page-aligned as an implementation artifact, which can - severely harm CPU cache utilization. However, the cache-oblivious layout - comes at the cost of one extra page per large allocation, which in the - most extreme case increases physical memory usage for the 16 KiB size class - to 20 KiB. - ---with-xslroot= - Specify where to find DocBook XSL stylesheets when building the - documentation. - ---with-lg-page= - Specify the base 2 log of the system page size.

This - option may be useful when cross-compiling in combination with - --with-lg-page, but its primary use case is for integration with FreeBSD's - libc, wherein jemalloc is embedded. - ---with-lg-size-class-group= - Specify the base 2 log of how many size classes to use for each doubling in - size. By default jemalloc uses =2, which results in - e.g. the following size classes: - - [...], 64, - 80, 96, 112, 128, - 160, [...] - - =3 results in e.g. the following size classes: - - [...], 64, - 72, 80, 88, 96, 104, 112, 120, 128, - 144, [...] - - The minimal =0 causes jemalloc to only provide size - classes that are powers of 2: - - [...], - 64, - 128, - 256, - [...] - - An implementation detail currently limits the total number of small size - classes to 255, and a compilation error will result if the - you specify cannot be supported. The limit is - roughly =4, depending on page size. - ---with-lg-quantum= - Specify the base 2 log of the minimum allocation alignment. jemalloc needs - to know the minimum alignment that meets the following C standard - requirement (quoted from the April 12, 2011 draft of the C11 standard): - - The pointer returned if the allocation succeeds is suitably aligned so - that it may be assigned to a pointer to any type of object with a - fundamental alignment requirement and then used to access such an object - or an array of such objects in the space allocated [...] - - This setting is architecture-specific, and although jemalloc includes known - safe values for the most commonly used modern architectures, there is a - wrinkle related to GNU libc (glibc) that may impact your choice of - . On most modern architectures, this mandates 16-byte alignment - (=4), but the glibc developers chose not to meet this - requirement for performance reasons. An old discussion can be found at - https://sourceware.org/bugzilla/show_bug.cgi?id=206 . Unlike glibc, - jemalloc does follow the C standard by default (caveat: jemalloc - technically cheats if --with-lg-tiny-min is smaller than - --with-lg-quantum), but the fact that Linux systems already work around - this allocator noncompliance means that it is generally safe in practice to - let jemalloc's minimum alignment follow glibc's lead. If you specify - --with-lg-quantum=3 during configuration, jemalloc will provide additional - size classes that are not 16-byte-aligned (24, 40, and 56, assuming - --with-lg-size-class-group=2). - ---with-lg-tiny-min= - Specify the base 2 log of the minimum tiny size class to support. Tiny - size classes are powers of 2 less than the quantum, and are only - incorporated if is less than (see - --with-lg-quantum). Tiny size classes technically violate the C standard - requirement for minimum alignment, and crashes could conceivably result if - the compiler were to generate instructions that made alignment assumptions, - both because illegal instruction traps could result, and because accesses - could straddle page boundaries and cause segmentation faults due to - accessing unmapped addresses. - - The default of =3 works well in practice even on architectures - that technically require 16-byte alignment, probably for the same reason - --with-lg-quantum=3 works. Smaller tiny size classes can, and will, cause - crashes (see https://bugzilla.mozilla.org/show_bug.cgi?id=691003 for an - example). - - This option is rarely useful, and is mainly provided as documentation of a - subtle implementation detail.

You probably shouldn't define this unless - you know what you are doing. (Use EXTRA_CFLAGS instead.) - -EXTRA_CFLAGS="?" - Append these flags to CFLAGS. This makes it possible to add flags such as - -Werror, while allowing the configure script to determine what other flags - are appropriate for the specified configuration. - - The configure script specifically checks whether an optimization flag (-O*) - is specified in EXTRA_CFLAGS, and refrains from specifying an optimization - level if it finds that one has already been specified. - -CPPFLAGS="?" - Pass these flags to the C preprocessor.

The minimum valid input size is the original requested size of the allocation, and the maximum valid input size is the corresponding value returned by -\fBnallocx\fR\fB\fR -or -\fBsallocx\fR\fB\fR\&. -.PP -The -\fBnallocx\fR\fB\fR -function allocates no memory, but it performs the same size computation as the -\fBmallocx\fR\fB\fR -function, and returns the real size of the allocation that would result from the equivalent -\fBmallocx\fR\fB\fR -function call\&. Behavior is undefined if -\fIsize\fR -is -\fB0\fR, or if request size overflows due to size class and/or alignment constraints\&. -.PP -The -\fBmallctl\fR\fB\fR -function provides a general interface for introspecting the memory allocator, as well as setting modifiable parameters and triggering actions\&. The period\-separated -\fIname\fR -argument specifies a location in a tree\-structured namespace; see the -MALLCTL NAMESPACE -section for documentation on the tree contents\&. To read a value, pass a pointer via -\fIoldp\fR -to adequate space to contain the value, and a pointer to its length via -\fIoldlenp\fR; otherwise pass -\fBNULL\fR -and -\fBNULL\fR\&. Similarly, to write a value, pass a pointer to the value via -\fInewp\fR, and its length via -\fInewlen\fR; otherwise pass -\fBNULL\fR -and -\fB0\fR\&. -.PP -The -\fBmallctlnametomib\fR\fB\fR -function provides a way to avoid repeated name lookups for applications that repeatedly query the same portion of the namespace, by translating a name to a \(lqManagement Information Base\(rq (MIB) that can be passed repeatedly to -\fBmallctlbymib\fR\fB\fR\&. Upon successful return from -\fBmallctlnametomib\fR\fB\fR, -\fImibp\fR -contains an array of -\fI*miblenp\fR -integers, where -\fI*miblenp\fR -is the lesser of the number of components in -\fIname\fR -and the input value of -\fI*miblenp\fR\&. Thus it is possible to pass a -\fI*miblenp\fR -that is smaller than the number of period\-separated name components, which results in a partial MIB that can be used as the basis for constructing a complete MIB\&. For name components that are integers (e\&.g\&. the 2 in -"arenas\&.bin\&.2\&.size"), the corresponding MIB component will always be that integer\&. Therefore, it is legitimate to construct code like the following: -.sp -.if n \{\ -.RS 4 -.\} -.nf -unsigned nbins, i; -size_t mib[4]; -size_t len, miblen; - -len = sizeof(nbins); -mallctl("arenas\&.nbins", &nbins, &len, NULL, 0); - -miblen = 4; -mallctlnametomib("arenas\&.bin\&.0\&.size", mib, &miblen); -for (i = 0; i < nbins; i++) { - size_t bin_size; - - mib[2] = i; - len = sizeof(bin_size); - mallctlbymib(mib, miblen, &bin_size, &len, NULL, 0); - /* Do something with bin_size\&.\&.\&. */ -} -.fi -.if n \{\ -.RE -.\} -.PP -The -\fBmalloc_stats_print\fR\fB\fR -function writes human\-readable summary statistics via the -\fIwrite_cb\fR -callback function pointer and -\fIcbopaque\fR -data passed to -\fIwrite_cb\fR, or -\fBmalloc_message\fR\fB\fR -if -\fIwrite_cb\fR -is -\fBNULL\fR\&. This function can be called repeatedly\&. General information that never changes during execution can be omitted by specifying "g" as a character within the -\fIopts\fR -string\&. Note that -\fBmalloc_message\fR\fB\fR -uses the -\fBmallctl*\fR\fB\fR -functions internally, so inconsistent statistics can be reported if multiple threads use these functions simultaneously\&. If -\fB\-\-enable\-stats\fR -is specified during configuration, \(lqm\(rq and \(lqa\(rq can be specified to omit merged arena and per arena statistics, respectively; \(lqb\(rq, \(lql\(rq, and \(lqh\(rq can be specified to omit per size class statistics for bins, large objects, and huge objects, respectively\&. Unrecognized characters are silently ignored\&. Note that thread caching may prevent some statistics from being completely up to date, since extra locking would be required to merge counters that track thread cache operations\&. -.PP -The -\fBmalloc_usable_size\fR\fB\fR -function returns the usable size of the allocation pointed to by -\fIptr\fR\&. The return value may be larger than the size that was requested during allocation\&. The -\fBmalloc_usable_size\fR\fB\fR -function is not a mechanism for in\-place -\fBrealloc\fR\fB\fR; rather it is provided solely as a tool for introspection purposes\&. Any discrepancy between the requested allocation size and the size reported by -\fBmalloc_usable_size\fR\fB\fR -should not be depended on, since such behavior is entirely implementation\-dependent\&. -.SH "TUNING" -.PP -Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile\- or run\-time\&. -.PP -The string pointed to by the global variable -\fImalloc_conf\fR, the \(lqname\(rq of the file referenced by the symbolic link named -/etc/malloc\&.conf, and the value of the environment variable -\fBMALLOC_CONF\fR, will be interpreted, in that order, from left to right as options\&. Note that -\fImalloc_conf\fR -may be read before -\fBmain\fR\fB\fR -is entered, so the declaration of -\fImalloc_conf\fR -should specify an initializer that contains the final value to be read by jemalloc\&. -\fImalloc_conf\fR -is a compile\-time setting, whereas -/etc/malloc\&.conf -and -\fBMALLOC_CONF\fR -can be safely set any time prior to program invocation\&. -.PP -An options string is a comma\-separated list of option:value pairs\&. There is one key corresponding to each -"opt\&.*" -mallctl (see the -MALLCTL NAMESPACE -section for options documentation)\&. For example, -abort:true,narenas:1 -sets the -"opt\&.abort" -and -"opt\&.narenas" -options\&. Some options have boolean values (true/false), others have integer values (base 8, 10, or 16, depending on prefix), and yet others have raw string values\&. -.SH "IMPLEMENTATION NOTES" -.PP -Traditionally, allocators have used -\fBsbrk\fR(2) -to obtain memory, which is suboptimal for several reasons, including race conditions, increased fragmentation, and artificial limitations on maximum usable memory\&. If -\fBsbrk\fR(2) -is supported by the operating system, this allocator uses both -\fBmmap\fR(2) -and -\fBsbrk\fR(2), in that order of preference; otherwise only -\fBmmap\fR(2) -is used\&. -.PP -This allocator uses multiple arenas in order to reduce lock contention for threaded programs on multi\-processor systems\&. This works well with regard to threading scalability, but incurs some costs\&. There is a small fixed per\-arena overhead, and additionally, arenas manage memory completely independently of each other, which means a small fixed increase in overall memory fragmentation\&. These overheads are not generally an issue, given the number of arenas normally used\&. Note that using substantially more arenas than the default is not likely to improve performance, mainly due to reduced cache performance\&. However, it may make sense to reduce the number of arenas if an application does not make much use of the allocation functions\&. -.PP -In addition to multiple arenas, unless -\fB\-\-disable\-tcache\fR -is specified during configuration, this allocator supports thread\-specific caching for small and large objects, in order to make it possible to completely avoid synchronization for most allocation requests\&. Such caching allows very fast allocation in the common case, but it increases memory usage and fragmentation, since a bounded number of objects can remain allocated in each thread cache\&. -.PP -Memory is conceptually broken into equal\-sized chunks, where the chunk size is a power of two that is greater than the page size\&. Chunks are always aligned to multiples of the chunk size\&. This alignment makes it possible to find metadata for user objects very quickly\&. -.PP -User objects are broken into three categories according to size: small, large, and huge\&. Small and large objects are managed entirely by arenas; huge objects are additionally aggregated in a single data structure that is shared by all threads\&. Huge objects are typically used by applications infrequently enough that this single data structure is not a scalability issue\&. -.PP -Each chunk that is managed by an arena tracks its contents as runs of contiguous pages (unused, backing a set of small objects, or backing one large object)\&. The combination of chunk alignment and chunk page maps makes it possible to determine all metadata regarding small and large allocations in constant time\&. -.PP -Small objects are managed in groups by page runs\&. Each run maintains a bitmap to track which regions are in use\&. Allocation requests that are no more than half the quantum (8 or 16, depending on architecture) are rounded up to the nearest power of two that is at least -sizeof(\fBdouble\fR)\&. All other object size classes are multiples of the quantum, spaced such that there are four size classes for each doubling in size, which limits internal fragmentation to approximately 20% for all but the smallest size classes\&. Small size classes are smaller than four times the page size, large size classes are smaller than the chunk size (see the -"opt\&.lg_chunk" -option), and huge size classes extend from the chunk size up to one size class less than the full address space size\&. -.PP -Allocations are packed tightly together, which can be an issue for multi\-threaded applications\&. If you need to assure that allocations do not suffer from cacheline sharing, round your allocation requests up to the nearest multiple of the cacheline size, or specify cacheline alignment when allocating\&. -.PP -The -\fBrealloc\fR\fB\fR, -\fBrallocx\fR\fB\fR, and -\fBxallocx\fR\fB\fR -functions may resize allocations without moving them under limited circumstances\&. Unlike the -\fB*allocx\fR\fB\fR -API, the standard API does not officially round up the usable size of an allocation to the nearest size class, so technically it is necessary to call -\fBrealloc\fR\fB\fR -to grow e\&.g\&. a 9\-byte allocation to 16 bytes, or shrink a 16\-byte allocation to 9 bytes\&. Growth and shrinkage trivially succeeds in place as long as the pre\-size and post\-size both round up to the same size class\&. No other API guarantees are made regarding in\-place resizing, but the current implementation also tries to resize large and huge allocations in place, as long as the pre\-size and post\-size are both large or both huge\&. In such cases shrinkage always succeeds for large size classes, but for huge size classes the chunk allocator must support splitting (see -"arena\&.\&.chunk_hooks")\&. Growth only succeeds if the trailing memory is currently available, and additionally for huge size classes the chunk allocator must support merging\&. -.PP -Assuming 2 MiB chunks, 4 KiB pages, and a 16\-byte quantum on a 64\-bit system, the size classes in each category are as shown in -Table 1\&. -.sp -.it 1 an-trap -.nr an-no-space-flag 1 -.nr an-break-flag 1 -.br -.B Table\ \&1.\ \&Size classes -.TS -allbox tab(:); -lB rB lB. -T{ -Category -T}:T{ -Spacing -T}:T{ -Size -T} -.T& -l r l -^ r l -^ r l -^ r l -^ r l -^ r l -^ r l -^ r l -^ r l -l r l -^ r l -^ r l -^ r l -^ r l -^ r l -^ r l -^ r l -l r l -^ r l -^ r l -^ r l -^ r l -^ r l -^ r l. -T{ -Small -T}:T{ -lg -T}:T{ -[8] -T} -:T{ -16 -T}:T{ -[16, 32, 48, 64, 80, 96, 112, 128] -T} -:T{ -32 -T}:T{ -[160, 192, 224, 256] -T} -:T{ -64 -T}:T{ -[320, 384, 448, 512] -T} -:T{ -128 -T}:T{ -[640, 768, 896, 1024] -T} -:T{ -256 -T}:T{ -[1280, 1536, 1792, 2048] -T} -:T{ -512 -T}:T{ -[2560, 3072, 3584, 4096] -T} -:T{ -1 KiB -T}:T{ -[5 KiB, 6 KiB, 7 KiB, 8 KiB] -T} -:T{ -2 KiB -T}:T{ -[10 KiB, 12 KiB, 14 KiB] -T} -T{ -Large -T}:T{ -2 KiB -T}:T{ -[16 KiB] -T} -:T{ -4 KiB -T}:T{ -[20 KiB, 24 KiB, 28 KiB, 32 KiB] -T} -:T{ -8 KiB -T}:T{ -[40 KiB, 48 KiB, 54 KiB, 64 KiB] -T} -:T{ -16 KiB -T}:T{ -[80 KiB, 96 KiB, 112 KiB, 128 KiB] -T} -:T{ -32 KiB -T}:T{ -[160 KiB, 192 KiB, 224 KiB, 256 KiB] -T} -:T{ -64 KiB -T}:T{ -[320 KiB, 384 KiB, 448 KiB, 512 KiB] -T} -:T{ -128 KiB -T}:T{ -[640 KiB, 768 KiB, 896 KiB, 1 MiB] -T} -:T{ -256 KiB -T}:T{ -[1280 KiB, 1536 KiB, 1792 KiB] -T} -T{ -Huge -T}:T{ -256 KiB -T}:T{ -[2 MiB] -T} -:T{ -512 KiB -T}:T{ -[2560 KiB, 3 MiB, 3584 KiB, 4 MiB] -T} -:T{ -1 MiB -T}:T{ -[5 MiB, 6 MiB, 7 MiB, 8 MiB] -T} -:T{ -2 MiB -T}:T{ -[10 MiB, 12 MiB, 14 MiB, 16 MiB] -T} -:T{ -4 MiB -T}:T{ -[20 MiB, 24 MiB, 28 MiB, 32 MiB] -T} -:T{ -8 MiB -T}:T{ -[40 MiB, 48 MiB, 56 MiB, 64 MiB] -T} -:T{ -\&.\&.\&. -T}:T{ -\&.\&.\&. -T} -.TE -.sp 1 -.SH "MALLCTL NAMESPACE" -.PP -The following names are defined in the namespace accessible via the -\fBmallctl*\fR\fB\fR -functions\&.

DESCRIPTION

Standard API

The malloc() function allocates - size bytes of uninitialized memory. The allocated - space is suitably aligned (after possible pointer coercion) for storage - of any type of object.

The calloc() function allocates - space for number objects, each - size bytes in length. The result is identical to - calling malloc() with an argument of - number * size, with the - exception that the allocated memory is explicitly initialized to zero - bytes.

The posix_memalign() function - allocates size bytes of memory such that the - allocation's base address is a multiple of - alignment, and returns the allocation in the value - pointed to by ptr. The requested - alignment must be a power of 2 at least as large as - sizeof(void *).

The aligned_alloc() function - allocates size bytes of memory such that the - allocation's base address is a multiple of - alignment. The requested - alignment must be a power of 2. Behavior is - undefined if size is not an integral multiple of - alignment.

The realloc() function changes the - size of the previously allocated memory referenced by - ptr to size bytes. The - contents of the memory are unchanged up to the lesser of the new and old - sizes. If the new size is larger, the contents of the newly allocated - portion of the memory are undefined. Upon success, the memory referenced - by ptr is freed and a pointer to the newly - allocated memory is returned. Note that - realloc() may move the memory allocation, - resulting in a different return value than ptr. - If ptr is NULL, the - realloc() function behaves identically to - malloc() for the specified size.

The free() function causes the - allocated memory referenced by ptr to be made - available for future allocations. If ptr is - NULL, no action occurs.

Non-standard API

The mallocx(), - rallocx(), - xallocx(), - sallocx(), - dallocx(), - sdallocx(), and - nallocx() functions all have a - flags argument that can be used to specify - options. The functions only check the options that are contextually - relevant. Use bitwise or (|) operations to - specify one or more of the following: -

MALLOCX_LG_ALIGN(la) -

Align the memory allocation to start at an address - that is a multiple of (1 << - la). This macro does not validate - that la is within the valid - range.

MALLOCX_ALIGN(a) -

Align the memory allocation to start at an address - that is a multiple of a, where - a is a power of two. This macro does not - validate that a is a power of 2. -

MALLOCX_ZERO

Initialize newly allocated memory to contain zero - bytes. In the growing reallocation case, the real size prior to - reallocation defines the boundary between untouched bytes and those - that are initialized to contain zero bytes. If this macro is - absent, newly allocated memory is uninitialized.

MALLOCX_TCACHE(tc) -

Use the thread-specific cache (tcache) specified by - the identifier tc, which must have been - acquired via the - "tcache.create" - - mallctl. This macro does not validate that - tc specifies a valid - identifier.

MALLOCX_TCACHE_NONE

Do not use a thread-specific cache (tcache). Unless - MALLOCX_TCACHE(tc) or - MALLOCX_TCACHE_NONE is specified, an - automatically managed tcache will be used under many circumstances. - This macro cannot be used in the same flags - argument as - MALLOCX_TCACHE(tc).

MALLOCX_ARENA(a) -

Use the arena specified by the index - a. This macro has no effect for regions that - were allocated via an arena other than the one specified. This - macro does not validate that a specifies an - arena index in the valid range.

-

The mallocx() function allocates at - least size bytes of memory, and returns a pointer - to the base address of the allocation. Behavior is undefined if - size is 0, or if request size - overflows due to size class and/or alignment constraints.

The rallocx() function resizes the - allocation at ptr to be at least - size bytes, and returns a pointer to the base - address of the resulting allocation, which may or may not have moved from - its original location. Behavior is undefined if - size is 0, or if request size - overflows due to size class and/or alignment constraints.

The xallocx() function resizes the - allocation at ptr in place to be at least - size bytes, and returns the real size of the - allocation. If extra is non-zero, an attempt is - made to resize the allocation to be at least (size + - extra) bytes, though inability to allocate - the extra byte(s) will not by itself result in failure to resize. - Behavior is undefined if size is - 0, or if (size + extra - > SIZE_T_MAX).

The sallocx() function returns the - real size of the allocation at ptr.

The dallocx() function causes the - memory referenced by ptr to be made available for - future allocations.

The sdallocx() function is an - extension of dallocx() with a - size parameter to allow the caller to pass in the - allocation size as an optimization. The minimum valid input size is the - original requested size of the allocation, and the maximum valid input - size is the corresponding value returned by - nallocx() or - sallocx().

The nallocx() function allocates no - memory, but it performs the same size computation as the - mallocx() function, and returns the real - size of the allocation that would result from the equivalent - mallocx() function call. Behavior is - undefined if size is 0, or if - request size overflows due to size class and/or alignment - constraints.

The mallctl() function provides a - general interface for introspecting the memory allocator, as well as - setting modifiable parameters and triggering actions. The - period-separated name argument specifies a - location in a tree-structured namespace; see the MALLCTL NAMESPACE section for - documentation on the tree contents. To read a value, pass a pointer via - oldp to adequate space to contain the value, and a - pointer to its length via oldlenp; otherwise pass - NULL and NULL. Similarly, to - write a value, pass a pointer to the value via - newp, and its length via - newlen; otherwise pass NULL - and 0.

The mallctlnametomib() function - provides a way to avoid repeated name lookups for applications that - repeatedly query the same portion of the namespace, by translating a name - to a “Management Information Base” (MIB) that can be passed - repeatedly to mallctlbymib(). Upon - successful return from mallctlnametomib(), - mibp contains an array of - *miblenp integers, where - *miblenp is the lesser of the number of components - in name and the input value of - *miblenp. Thus it is possible to pass a - *miblenp that is smaller than the number of - period-separated name components, which results in a partial MIB that can - be used as the basis for constructing a complete MIB. For name - components that are integers (e.g. the 2 in - - "arenas.bin.2.size" - ), - the corresponding MIB component will always be that integer. Therefore, - it is legitimate to construct code like the following: 

-unsigned nbins, i;
-size_t mib[4];
-size_t len, miblen;
-
-len = sizeof(nbins);
-mallctl("arenas.nbins", &nbins, &len, NULL, 0);
-
-miblen = 4;
-mallctlnametomib("arenas.bin.0.size", mib, &miblen);
-for (i = 0; i < nbins; i++) {
-	size_t bin_size;
-
-	mib[2] = i;
-	len = sizeof(bin_size);
-	mallctlbymib(mib, miblen, &bin_size, &len, NULL, 0);
-	/* Do something with bin_size... */
-}

The malloc_stats_print() function - writes human-readable summary statistics via the - write_cb callback function pointer and - cbopaque data passed to - write_cb, or - malloc_message() if - write_cb is NULL. This - function can be called repeatedly. General information that never - changes during execution can be omitted by specifying "g" as a character - within the opts string. Note that - malloc_message() uses the - mallctl*() functions internally, so - inconsistent statistics can be reported if multiple threads use these - functions simultaneously. If --enable-stats is - specified during configuration, “m” and “a” can - be specified to omit merged arena and per arena statistics, respectively; - “b”, “l”, and “h” can be specified to - omit per size class statistics for bins, large objects, and huge objects, - respectively. Unrecognized characters are silently ignored. Note that - thread caching may prevent some statistics from being completely up to - date, since extra locking would be required to merge counters that track - thread cache operations. -

The malloc_usable_size() function - returns the usable size of the allocation pointed to by - ptr. The return value may be larger than the size - that was requested during allocation. The - malloc_usable_size() function is not a - mechanism for in-place realloc(); rather - it is provided solely as a tool for introspection purposes. Any - discrepancy between the requested allocation size and the size reported - by malloc_usable_size() should not be - depended on, since such behavior is entirely implementation-dependent. -

TUNING

Once, when the first call is made to one of the memory allocation - routines, the allocator initializes its internals based in part on various - options that can be specified at compile- or run-time.

The string pointed to by the global variable - malloc_conf, the “name” of the file - referenced by the symbolic link named /etc/malloc.conf, and the value of the - environment variable MALLOC_CONF, will be interpreted, in - that order, from left to right as options. Note that - malloc_conf may be read before - main() is entered, so the declaration of - malloc_conf should specify an initializer that contains - the final value to be read by jemalloc. malloc_conf is - a compile-time setting, whereas /etc/malloc.conf and MALLOC_CONF - can be safely set any time prior to program invocation.

An options string is a comma-separated list of option:value pairs. - There is one key corresponding to each - "opt.*" - mallctl (see the MALLCTL NAMESPACE section for options - documentation). For example, abort:true,narenas:1 sets - the - "opt.abort" - and - "opt.narenas" - options. Some - options have boolean values (true/false), others have integer values (base - 8, 10, or 16, depending on prefix), and yet others have raw string - values.

IMPLEMENTATION NOTES

Traditionally, allocators have used - sbrk(2) to obtain memory, which is - suboptimal for several reasons, including race conditions, increased - fragmentation, and artificial limitations on maximum usable memory. If - sbrk(2) is supported by the operating - system, this allocator uses both - mmap(2) and - sbrk(2), in that order of preference; - otherwise only mmap(2) is used.

This allocator uses multiple arenas in order to reduce lock - contention for threaded programs on multi-processor systems. This works - well with regard to threading scalability, but incurs some costs. There is - a small fixed per-arena overhead, and additionally, arenas manage memory - completely independently of each other, which means a small fixed increase - in overall memory fragmentation. These overheads are not generally an - issue, given the number of arenas normally used. Note that using - substantially more arenas than the default is not likely to improve - performance, mainly due to reduced cache performance. However, it may make - sense to reduce the number of arenas if an application does not make much - use of the allocation functions.

In addition to multiple arenas, unless - --disable-tcache is specified during configuration, this - allocator supports thread-specific caching for small and large objects, in - order to make it possible to completely avoid synchronization for most - allocation requests. Such caching allows very fast allocation in the - common case, but it increases memory usage and fragmentation, since a - bounded number of objects can remain allocated in each thread cache.

Memory is conceptually broken into equal-sized chunks, where the - chunk size is a power of two that is greater than the page size. Chunks - are always aligned to multiples of the chunk size. This alignment makes it - possible to find metadata for user objects very quickly.

User objects are broken into three categories according to size: - small, large, and huge. Small and large objects are managed entirely by - arenas; huge objects are additionally aggregated in a single data structure - that is shared by all threads. Huge objects are typically used by - applications infrequently enough that this single data structure is not a - scalability issue.

Each chunk that is managed by an arena tracks its contents as runs of - contiguous pages (unused, backing a set of small objects, or backing one - large object). The combination of chunk alignment and chunk page maps - makes it possible to determine all metadata regarding small and large - allocations in constant time.

Small objects are managed in groups by page runs. Each run maintains - a bitmap to track which regions are in use. Allocation requests that are no - more than half the quantum (8 or 16, depending on architecture) are rounded - up to the nearest power of two that is at least sizeof(double). All other object size - classes are multiples of the quantum, spaced such that there are four size - classes for each doubling in size, which limits internal fragmentation to - approximately 20% for all but the smallest size classes. Small size classes - are smaller than four times the page size, large size classes are smaller - than the chunk size (see the - "opt.lg_chunk" - option), and - huge size classes extend from the chunk size up to one size class less than - the full address space size.

Allocations are packed tightly together, which can be an issue for - multi-threaded applications. If you need to assure that allocations do not - suffer from cacheline sharing, round your allocation requests up to the - nearest multiple of the cacheline size, or specify cacheline alignment when - allocating.

The realloc(), - rallocx(), and - xallocx() functions may resize allocations - without moving them under limited circumstances. Unlike the - *allocx() API, the standard API does not - officially round up the usable size of an allocation to the nearest size - class, so technically it is necessary to call - realloc() to grow e.g. a 9-byte allocation to - 16 bytes, or shrink a 16-byte allocation to 9 bytes. Growth and shrinkage - trivially succeeds in place as long as the pre-size and post-size both round - up to the same size class. No other API guarantees are made regarding - in-place resizing, but the current implementation also tries to resize large - and huge allocations in place, as long as the pre-size and post-size are - both large or both huge. In such cases shrinkage always succeeds for large - size classes, but for huge size classes the chunk allocator must support - splitting (see - "arena.<i>.chunk_hooks" - ). - Growth only succeeds if the trailing memory is currently available, and - additionally for huge size classes the chunk allocator must support - merging.

Assuming 2 MiB chunks, 4 KiB pages, and a 16-byte quantum on a - 64-bit system, the size classes in each category are as shown in Table 1.

MALLCTL NAMESPACE

The following names are defined in the namespace accessible via the - mallctl*() functions. Value types are - specified in parentheses, their readable/writable statuses are encoded as - rw, r-, -w, or - --, and required build configuration flags follow, if - any. A name element encoded as <i> or - <j> indicates an integer component, where the - integer varies from 0 to some upper value that must be determined via - introspection. In the case of - "stats.arenas.<i>.*" - , - <i> equal to - "arenas.narenas" - can be - used to access the summation of statistics from all arenas. Take special - note of the - "epoch" - mallctl, - which controls refreshing of cached dynamic statistics.

- - "version" - - (const char *) - r- -

Return the jemalloc version string.

- - "epoch" - - (uint64_t) - rw -

If a value is passed in, refresh the data from which - the mallctl*() functions report values, - and increment the epoch. Return the current epoch. This is useful for - detecting whether another thread caused a refresh.

- - "config.cache_oblivious" - - (bool) - r- -

--enable-cache-oblivious was specified - during build configuration.

- - "config.debug" - - (bool) - r- -

--enable-debug was specified during - build configuration.

- - "config.fill" - - (bool) - r- -

--enable-fill was specified during - build configuration.

- - "config.lazy_lock" - - (bool) - r- -

--enable-lazy-lock was specified - during build configuration.

- - "config.munmap" - - (bool) - r- -

--enable-munmap was specified during - build configuration.

- - "config.prof" - - (bool) - r- -

--enable-prof was specified during - build configuration.

- - "config.prof_libgcc" - - (bool) - r- -

--disable-prof-libgcc was not - specified during build configuration.

- - "config.prof_libunwind" - - (bool) - r- -

--enable-prof-libunwind was specified - during build configuration.

- - "config.stats" - - (bool) - r- -

--enable-stats was specified during - build configuration.

- - "config.tcache" - - (bool) - r- -

--disable-tcache was not specified - during build configuration.

- - "config.tls" - - (bool) - r- -

--disable-tls was not specified during - build configuration.

- - "config.utrace" - - (bool) - r- -

--enable-utrace was specified during - build configuration.

- - "config.valgrind" - - (bool) - r- -

--enable-valgrind was specified during - build configuration.

- - "config.xmalloc" - - (bool) - r- -

--enable-xmalloc was specified during - build configuration.

- - "opt.abort" - - (bool) - r- -

Abort-on-warning enabled/disabled. If true, most - warnings are fatal. The process will call - abort(3) in these cases. This option is - disabled by default unless --enable-debug is - specified during configuration, in which case it is enabled by default. -

- - "opt.dss" - - (const char *) - r- -

dss (sbrk(2)) allocation precedence as - related to mmap(2) allocation. The following - settings are supported if - sbrk(2) is supported by the operating - system: “disabled”, “primary”, and - “secondary”; otherwise only “disabled” is - supported. The default is “secondary” if - sbrk(2) is supported by the operating - system; “disabled” otherwise. -

- - "opt.lg_chunk" - - (size_t) - r- -

Virtual memory chunk size (log base 2). If a chunk - size outside the supported size range is specified, the size is - silently clipped to the minimum/maximum supported size. The default - chunk size is 2 MiB (2^21). -

- - "opt.narenas" - - (size_t) - r- -

Maximum number of arenas to use for automatic - multiplexing of threads and arenas. The default is four times the - number of CPUs, or one if there is a single CPU.

- - "opt.lg_dirty_mult" - - (ssize_t) - r- -

Per-arena minimum ratio (log base 2) of active to dirty - pages. Some dirty unused pages may be allowed to accumulate, within - the limit set by the ratio (or one chunk worth of dirty pages, - whichever is greater), before informing the kernel about some of those - pages via madvise(2) or a similar system call. This - provides the kernel with sufficient information to recycle dirty pages - if physical memory becomes scarce and the pages remain unused. The - default minimum ratio is 8:1 (2^3:1); an option value of -1 will - disable dirty page purging. See - "arenas.lg_dirty_mult" - - and - "arena.<i>.lg_dirty_mult" - - for related dynamic control options.

- - "opt.stats_print" - - (bool) - r- -

Enable/disable statistics printing at exit. If - enabled, the malloc_stats_print() - function is called at program exit via an - atexit(3) function. If - --enable-stats is specified during configuration, this - has the potential to cause deadlock for a multi-threaded process that - exits while one or more threads are executing in the memory allocation - functions. Furthermore, atexit() may - allocate memory during application initialization and then deadlock - internally when jemalloc in turn calls - atexit(), so this option is not - univerally usable (though the application can register its own - atexit() function with equivalent - functionality). Therefore, this option should only be used with care; - it is primarily intended as a performance tuning aid during application - development. This option is disabled by default.

- - "opt.junk" - - (const char *) - r- - [--enable-fill] -

Junk filling. If set to "alloc", each byte of - uninitialized allocated memory will be initialized to - 0xa5. If set to "free", all deallocated memory will - be initialized to 0x5a. If set to "true", both - allocated and deallocated memory will be initialized, and if set to - "false", junk filling be disabled entirely. This is intended for - debugging and will impact performance negatively. This option is - "false" by default unless --enable-debug is specified - during configuration, in which case it is "true" by default unless - running inside Valgrind.

- - "opt.quarantine" - - (size_t) - r- - [--enable-fill] -

Per thread quarantine size in bytes. If non-zero, each - thread maintains a FIFO object quarantine that stores up to the - specified number of bytes of memory. The quarantined memory is not - freed until it is released from quarantine, though it is immediately - junk-filled if the - "opt.junk" - option is - enabled. This feature is of particular use in combination with Valgrind, which can detect attempts - to access quarantined objects. This is intended for debugging and will - impact performance negatively. The default quarantine size is 0 unless - running inside Valgrind, in which case the default is 16 - MiB.

- - "opt.redzone" - - (bool) - r- - [--enable-fill] -

Redzones enabled/disabled. If enabled, small - allocations have redzones before and after them. Furthermore, if the - - "opt.junk" - option is - enabled, the redzones are checked for corruption during deallocation. - However, the primary intended purpose of this feature is to be used in - combination with Valgrind, - which needs redzones in order to do effective buffer overflow/underflow - detection. This option is intended for debugging and will impact - performance negatively. This option is disabled by - default unless running inside Valgrind.

- - "opt.zero" - - (bool) - r- - [--enable-fill] -

Zero filling enabled/disabled. If enabled, each byte - of uninitialized allocated memory will be initialized to 0. Note that - this initialization only happens once for each byte, so - realloc() and - rallocx() calls do not zero memory that - was previously allocated. This is intended for debugging and will - impact performance negatively. This option is disabled by default. -

- - "opt.utrace" - - (bool) - r- - [--enable-utrace] -

Allocation tracing based on - utrace(2) enabled/disabled. This option - is disabled by default.

- - "opt.xmalloc" - - (bool) - r- - [--enable-xmalloc] -

Abort-on-out-of-memory enabled/disabled. If enabled, - rather than returning failure for any allocation function, display a - diagnostic message on STDERR_FILENO and cause the - program to drop core (using - abort(3)). If an application is - designed to depend on this behavior, set the option at compile time by - including the following in the source code: - 

-malloc_conf = "xmalloc:true";

- This option is disabled by default.

- - "opt.tcache" - - (bool) - r- - [--enable-tcache] -

Thread-specific caching (tcache) enabled/disabled. When - there are multiple threads, each thread uses a tcache for objects up to - a certain size. Thread-specific caching allows many allocations to be - satisfied without performing any thread synchronization, at the cost of - increased memory use. See the - "opt.lg_tcache_max" - - option for related tuning information. This option is enabled by - default unless running inside Valgrind, in which case it is - forcefully disabled.

- - "opt.lg_tcache_max" - - (size_t) - r- - [--enable-tcache] -

Maximum size class (log base 2) to cache in the - thread-specific cache (tcache). At a minimum, all small size classes - are cached, and at a maximum all large size classes are cached. The - default maximum is 32 KiB (2^15).

- - "opt.prof" - - (bool) - r- - [--enable-prof] -

Memory profiling enabled/disabled. If enabled, profile - memory allocation activity. See the - "opt.prof_active" - - option for on-the-fly activation/deactivation. See the - "opt.lg_prof_sample" - - option for probabilistic sampling control. See the - "opt.prof_accum" - - option for control of cumulative sample reporting. See the - "opt.lg_prof_interval" - - option for information on interval-triggered profile dumping, the - "opt.prof_gdump" - - option for information on high-water-triggered profile dumping, and the - - "opt.prof_final" - - option for final profile dumping. Profile output is compatible with - the jeprof command, which is based on the - pprof that is developed as part of the gperftools - package.

- - "opt.prof_prefix" - - (const char *) - r- - [--enable-prof] -

Filename prefix for profile dumps. If the prefix is - set to the empty string, no automatic dumps will occur; this is - primarily useful for disabling the automatic final heap dump (which - also disables leak reporting, if enabled). The default prefix is - jeprof.

- - "opt.prof_active" - - (bool) - r- - [--enable-prof] -

Profiling activated/deactivated. This is a secondary - control mechanism that makes it possible to start the application with - profiling enabled (see the - "opt.prof" - option) but - inactive, then toggle profiling at any time during program execution - with the - "prof.active" - mallctl. - This option is enabled by default.

- - "opt.prof_thread_active_init" - - (bool) - r- - [--enable-prof] -

Initial setting for - "thread.prof.active" - - in newly created threads. The initial setting for newly created threads - can also be changed during execution via the - "prof.thread_active_init" - - mallctl. This option is enabled by default.

- - "opt.lg_prof_sample" - - (size_t) - r- - [--enable-prof] -

Average interval (log base 2) between allocation - samples, as measured in bytes of allocation activity. Increasing the - sampling interval decreases profile fidelity, but also decreases the - computational overhead. The default sample interval is 512 KiB (2^19 - B).

- - "opt.prof_accum" - - (bool) - r- - [--enable-prof] -

Reporting of cumulative object/byte counts in profile - dumps enabled/disabled. If this option is enabled, every unique - backtrace must be stored for the duration of execution. Depending on - the application, this can impose a large memory overhead, and the - cumulative counts are not always of interest. This option is disabled - by default.

- - "opt.lg_prof_interval" - - (ssize_t) - r- - [--enable-prof] -

Average interval (log base 2) between memory profile - dumps, as measured in bytes of allocation activity. The actual - interval between dumps may be sporadic because decentralized allocation - counters are used to avoid synchronization bottlenecks. Profiles are - dumped to files named according to the pattern - <prefix>.<pid>.<seq>.i<iseq>.heap, - where <prefix> is controlled by the - - "opt.prof_prefix" - - option. By default, interval-triggered profile dumping is disabled - (encoded as -1). -

- - "opt.prof_gdump" - - (bool) - r- - [--enable-prof] -

Set the initial state of - "prof.gdump" - , which when - enabled triggers a memory profile dump every time the total virtual - memory exceeds the previous maximum. This option is disabled by - default.

- - "opt.prof_final" - - (bool) - r- - [--enable-prof] -

Use an - atexit(3) function to dump final memory - usage to a file named according to the pattern - <prefix>.<pid>.<seq>.f.heap, - where <prefix> is controlled by the - "opt.prof_prefix" - - option. Note that atexit() may allocate - memory during application initialization and then deadlock internally - when jemalloc in turn calls atexit(), so - this option is not univerally usable (though the application can - register its own atexit() function with - equivalent functionality). This option is disabled by - default.

- - "opt.prof_leak" - - (bool) - r- - [--enable-prof] -

Leak reporting enabled/disabled. If enabled, use an - atexit(3) function to report memory leaks - detected by allocation sampling. See the - - "opt.prof" - option for - information on analyzing heap profile output. This option is disabled - by default.

- - "thread.arena" - - (unsigned) - rw -

Get or set the arena associated with the calling - thread. If the specified arena was not initialized beforehand (see the - - "arenas.initialized" - - mallctl), it will be automatically initialized as a side effect of - calling this interface.

- - "thread.allocated" - - (uint64_t) - r- - [--enable-stats] -

Get the total number of bytes ever allocated by the - calling thread. This counter has the potential to wrap around; it is - up to the application to appropriately interpret the counter in such - cases.

- - "thread.allocatedp" - - (uint64_t *) - r- - [--enable-stats] -

Get a pointer to the the value that is returned by the - - "thread.allocated" - - mallctl. This is useful for avoiding the overhead of repeated - mallctl*() calls.

- - "thread.deallocated" - - (uint64_t) - r- - [--enable-stats] -

Get the total number of bytes ever deallocated by the - calling thread. This counter has the potential to wrap around; it is - up to the application to appropriately interpret the counter in such - cases.

- - "thread.deallocatedp" - - (uint64_t *) - r- - [--enable-stats] -

Get a pointer to the the value that is returned by the - - "thread.deallocated" - - mallctl. This is useful for avoiding the overhead of repeated - mallctl*() calls.

- - "thread.tcache.enabled" - - (bool) - rw - [--enable-tcache] -

Enable/disable calling thread's tcache. The tcache is - implicitly flushed as a side effect of becoming - disabled (see - "thread.tcache.flush" - ). -

- - "thread.tcache.flush" - - (void) - -- - [--enable-tcache] -

Flush calling thread's thread-specific cache (tcache). - This interface releases all cached objects and internal data structures - associated with the calling thread's tcache. Ordinarily, this interface - need not be called, since automatic periodic incremental garbage - collection occurs, and the thread cache is automatically discarded when - a thread exits. However, garbage collection is triggered by allocation - activity, so it is possible for a thread that stops - allocating/deallocating to retain its cache indefinitely, in which case - the developer may find manual flushing useful.

- - "thread.prof.name" - - (const char *) - r- or - -w - [--enable-prof] -

Get/set the descriptive name associated with the calling - thread in memory profile dumps. An internal copy of the name string is - created, so the input string need not be maintained after this interface - completes execution. The output string of this interface should be - copied for non-ephemeral uses, because multiple implementation details - can cause asynchronous string deallocation. Furthermore, each - invocation of this interface can only read or write; simultaneous - read/write is not supported due to string lifetime limitations. The - name string must nil-terminated and comprised only of characters in the - sets recognized - by isgraph(3) and - isblank(3).

- - "thread.prof.active" - - (bool) - rw - [--enable-prof] -

Control whether sampling is currently active for the - calling thread. This is an activation mechanism in addition to - "prof.active" - ; both must - be active for the calling thread to sample. This flag is enabled by - default.

- - "tcache.create" - - (unsigned) - r- - [--enable-tcache] -

Create an explicit thread-specific cache (tcache) and - return an identifier that can be passed to the MALLOCX_TCACHE(tc) - macro to explicitly use the specified cache rather than the - automatically managed one that is used by default. Each explicit cache - can be used by only one thread at a time; the application must assure - that this constraint holds. -

- - "tcache.flush" - - (unsigned) - -w - [--enable-tcache] -

Flush the specified thread-specific cache (tcache). The - same considerations apply to this interface as to - "thread.tcache.flush" - , - except that the tcache will never be automatically be discarded. -

- - "tcache.destroy" - - (unsigned) - -w - [--enable-tcache] -

Flush the specified thread-specific cache (tcache) and - make the identifier available for use during a future tcache creation. -

- - "arena.<i>.purge" - - (void) - -- -

Purge unused dirty pages for arena <i>, or for - all arenas if <i> equals - "arenas.narenas" - . -

- - "arena.<i>.dss" - - (const char *) - rw -

Set the precedence of dss allocation as related to mmap - allocation for arena <i>, or for all arenas if <i> equals - - "arenas.narenas" - . See - - "opt.dss" - for supported - settings.

- - "arena.<i>.lg_dirty_mult" - - (ssize_t) - rw -

Current per-arena minimum ratio (log base 2) of active - to dirty pages for arena <i>. Each time this interface is set and - the ratio is increased, pages are synchronously purged as necessary to - impose the new ratio. See - "opt.lg_dirty_mult" - - for additional information.

- - "arena.<i>.chunk_hooks" - - (chunk_hooks_t) - rw -

Get or set the chunk management hook functions for arena - <i>. The functions must be capable of operating on all extant - chunks associated with arena <i>, usually by passing unknown - chunks to the replaced functions. In practice, it is feasible to - control allocation for arenas created via - "arenas.extend" - such - that all chunks originate from an application-supplied chunk allocator - (by setting custom chunk hook functions just after arena creation), but - the automatically created arenas may have already created chunks prior - to the application having an opportunity to take over chunk - allocation.

-typedef struct {
-	chunk_alloc_t		*alloc;
-	chunk_dalloc_t		*dalloc;
-	chunk_commit_t		*commit;
-	chunk_decommit_t	*decommit;
-	chunk_purge_t		*purge;
-	chunk_split_t		*split;
-	chunk_merge_t		*merge;
-} chunk_hooks_t;

The chunk_hooks_t structure comprises function - pointers which are described individually below. jemalloc uses these - functions to manage chunk lifetime, which starts off with allocation of - mapped committed memory, in the simplest case followed by deallocation. - However, there are performance and platform reasons to retain chunks for - later reuse. Cleanup attempts cascade from deallocation to decommit to - purging, which gives the chunk management functions opportunities to - reject the most permanent cleanup operations in favor of less permanent - (and often less costly) operations. The chunk splitting and merging - operations can also be opted out of, but this is mainly intended to - support platforms on which virtual memory mappings provided by the - operating system kernel do not automatically coalesce and split, e.g. - Windows.

typedef void *(chunk_alloc_t)(void *chunk,
 size_t size,
 size_t alignment,
 bool *zero,
 bool *commit,
 unsigned arena_ind);
 

A chunk allocation function conforms to the - chunk_alloc_t type and upon success returns a pointer to - size bytes of mapped memory on behalf of arena - arena_ind such that the chunk's base address is a - multiple of alignment, as well as setting - *zero to indicate whether the chunk is zeroed and - *commit to indicate whether the chunk is - committed. Upon error the function returns NULL - and leaves *zero and - *commit unmodified. The - size parameter is always a multiple of the chunk - size. The alignment parameter is always a power - of two at least as large as the chunk size. Zeroing is mandatory if - *zero is true upon function entry. Committing is - mandatory if *commit is true upon function entry. - If chunk is not NULL, the - returned pointer must be chunk on success or - NULL on error. Committed memory may be committed - in absolute terms as on a system that does not overcommit, or in - implicit terms as on a system that overcommits and satisfies physical - memory needs on demand via soft page faults. Note that replacing the - default chunk allocation function makes the arena's - "arena.<i>.dss" - - setting irrelevant.

typedef bool (chunk_dalloc_t)(void *chunk,
 size_t size,
 bool committed,
 unsigned arena_ind);
 

- A chunk deallocation function conforms to the - chunk_dalloc_t type and deallocates a - chunk of given size with - committed/decommited memory as indicated, on - behalf of arena arena_ind, returning false upon - success. If the function returns true, this indicates opt-out from - deallocation; the virtual memory mapping associated with the chunk - remains mapped, in the same commit state, and available for future use, - in which case it will be automatically retained for later reuse.

typedef bool (chunk_commit_t)(void *chunk,
 size_t size,
 size_t offset,
 size_t length,
 unsigned arena_ind);
 

A chunk commit function conforms to the - chunk_commit_t type and commits zeroed physical memory to - back pages within a chunk of given - size at offset bytes, - extending for length on behalf of arena - arena_ind, returning false upon success. - Committed memory may be committed in absolute terms as on a system that - does not overcommit, or in implicit terms as on a system that - overcommits and satisfies physical memory needs on demand via soft page - faults. If the function returns true, this indicates insufficient - physical memory to satisfy the request.

typedef bool (chunk_decommit_t)(void *chunk,
 size_t size,
 size_t offset,
 size_t length,
 unsigned arena_ind);
 

A chunk decommit function conforms to the - chunk_decommit_t type and decommits any physical memory - that is backing pages within a chunk of given - size at offset bytes, - extending for length on behalf of arena - arena_ind, returning false upon success, in which - case the pages will be committed via the chunk commit function before - being reused. If the function returns true, this indicates opt-out from - decommit; the memory remains committed and available for future use, in - which case it will be automatically retained for later reuse.

typedef bool (chunk_purge_t)(void *chunk,
 size_tsize,
 size_t offset,
 size_t length,
 unsigned arena_ind);
 

A chunk purge function conforms to the chunk_purge_t - type and optionally discards physical pages within the virtual memory - mapping associated with chunk of given - size at offset bytes, - extending for length on behalf of arena - arena_ind, returning false if pages within the - purged virtual memory range will be zero-filled the next time they are - accessed.

typedef bool (chunk_split_t)(void *chunk,
 size_t size,
 size_t size_a,
 size_t size_b,
 bool committed,
 unsigned arena_ind);
 

A chunk split function conforms to the chunk_split_t - type and optionally splits chunk of given - size into two adjacent chunks, the first of - size_a bytes, and the second of - size_b bytes, operating on - committed/decommitted memory as indicated, on - behalf of arena arena_ind, returning false upon - success. If the function returns true, this indicates that the chunk - remains unsplit and therefore should continue to be operated on as a - whole.

typedef bool (chunk_merge_t)(void *chunk_a,
 size_t size_a,
 void *chunk_b,
 size_t size_b,
 bool committed,
 unsigned arena_ind);
 

A chunk merge function conforms to the chunk_merge_t - type and optionally merges adjacent chunks, - chunk_a of given size_a - and chunk_b of given - size_b into one contiguous chunk, operating on - committed/decommitted memory as indicated, on - behalf of arena arena_ind, returning false upon - success. If the function returns true, this indicates that the chunks - remain distinct mappings and therefore should continue to be operated on - independently.

- - "stats.cactive" - - (size_t *) - r- - [--enable-stats] -

Pointer to a counter that contains an approximate count - of the current number of bytes in active pages. The estimate may be - high, but never low, because each arena rounds up when computing its - contribution to the counter. Note that the - "epoch" - mallctl has no bearing - on this counter. Furthermore, counter consistency is maintained via - atomic operations, so it is necessary to use an atomic operation in - order to guarantee a consistent read when dereferencing the pointer. -

- - "stats.allocated" - - (size_t) - r- - [--enable-stats] -

Total number of bytes allocated by the - application.

- - "stats.active" - - (size_t) - r- - [--enable-stats] -

Total number of bytes in active pages allocated by the - application. This is a multiple of the page size, and greater than or - equal to - "stats.allocated" - . - This does not include - - "stats.arenas.<i>.pdirty" - , nor pages - entirely devoted to allocator metadata.

- - "stats.metadata" - - (size_t) - r- - [--enable-stats] -

- - "stats.resident" - - (size_t) - r- - [--enable-stats] -

Maximum number of bytes in physically resident data - pages mapped by the allocator, comprising all pages dedicated to - allocator metadata, pages backing active allocations, and unused dirty - pages. This is a maximum rather than precise because pages may not - actually be physically resident if they correspond to demand-zeroed - virtual memory that has not yet been touched. This is a multiple of the - page size, and is larger than - "stats.active" - .

- - "stats.mapped" - - (size_t) - r- - [--enable-stats] -

Total number of bytes in active chunks mapped by the - allocator. This is a multiple of the chunk size, and is larger than - - "stats.active" - . - This does not include inactive chunks, even those that contain unused - dirty pages, which means that there is no strict ordering between this - and - "stats.resident" - .

- - "stats.arenas.<i>.metadata.allocated" - - (size_t) - r- - [--enable-stats] -

Number of bytes dedicated to internal allocations. - Internal allocations differ from application-originated allocations in - that they are for internal use, and that they are omitted from heap - profiles. This statistic is reported separately from - "stats.metadata" - and - - "stats.arenas.<i>.metadata.mapped" - - because it overlaps with e.g. the - "stats.allocated" - and - - "stats.active" - - statistics, whereas the other metadata statistics do - not.

DEBUGGING MALLOC PROBLEMS

When debugging, it is a good idea to configure/build jemalloc with - the --enable-debug and --enable-fill - options, and recompile the program with suitable options and symbols for - debugger support. When so configured, jemalloc incorporates a wide variety - of run-time assertions that catch application errors such as double-free, - write-after-free, etc.

Programs often accidentally depend on “uninitialized” - memory actually being filled with zero bytes. Junk filling - (see the - "opt.junk" - - option) tends to expose such bugs in the form of obviously incorrect - results and/or coredumps. Conversely, zero - filling (see the - "opt.zero" - option) eliminates - the symptoms of such bugs. Between these two options, it is usually - possible to quickly detect, diagnose, and eliminate such bugs.

This implementation does not provide much detail about the problems - it detects, because the performance impact for storing such information - would be prohibitive. However, jemalloc does integrate with the most - excellent Valgrind tool if the - --enable-valgrind configuration option is enabled.

DIAGNOSTIC MESSAGES

If any of the memory allocation/deallocation functions detect an - error or warning condition, a message will be printed to file descriptor - STDERR_FILENO. Errors will result in the process - dumping core. If the - "opt.abort" - option is set, most - warnings are treated as errors.

The malloc_message variable allows the programmer - to override the function which emits the text strings forming the errors - and warnings if for some reason the STDERR_FILENO file - descriptor is not suitable for this. - malloc_message() takes the - cbopaque pointer argument that is - NULL unless overridden by the arguments in a call to - malloc_stats_print(), followed by a string - pointer. Please note that doing anything which tries to allocate memory in - this function is likely to result in a crash or deadlock.

All messages are prefixed by - “<jemalloc>: ”.

RETURN VALUES

Standard API

The malloc() and - calloc() functions return a pointer to the - allocated memory if successful; otherwise a NULL - pointer is returned and errno is set to - ENOMEM.

The posix_memalign() function - returns the value 0 if successful; otherwise it returns an error value. - The posix_memalign() function will fail - if: -

EINVAL

The alignment parameter is - not a power of 2 at least as large as - sizeof(void *). -

ENOMEM

Memory allocation error.

-

The aligned_alloc() function returns - a pointer to the allocated memory if successful; otherwise a - NULL pointer is returned and - errno is set. The - aligned_alloc() function will fail if: -

EINVAL

The alignment parameter is - not a power of 2. -

ENOMEM

Memory allocation error.

-

The realloc() function returns a - pointer, possibly identical to ptr, to the - allocated memory if successful; otherwise a NULL - pointer is returned, and errno is set to - ENOMEM if the error was the result of an - allocation failure. The realloc() - function always leaves the original buffer intact when an error occurs. -

The free() function returns no - value.

Non-standard API

The mallocx() and - rallocx() functions return a pointer to - the allocated memory if successful; otherwise a NULL - pointer is returned to indicate insufficient contiguous memory was - available to service the allocation request.

The xallocx() function returns the - real size of the resulting resized allocation pointed to by - ptr, which is a value less than - size if the allocation could not be adequately - grown in place.

The sallocx() function returns the - real size of the allocation pointed to by ptr. -

The nallocx() returns the real size - that would result from a successful equivalent - mallocx() function call, or zero if - insufficient memory is available to perform the size computation.

The mallctl(), - mallctlnametomib(), and - mallctlbymib() functions return 0 on - success; otherwise they return an error value. The functions will fail - if: -

EINVAL

newp is not - NULL, and newlen is too - large or too small. Alternatively, *oldlenp - is too large or too small; in this case as much data as possible - are read despite the error.

ENOENT

name or - mib specifies an unknown/invalid - value.

EPERM

Attempt to read or write void value, or attempt to - write read-only value.

EAGAIN

A memory allocation failure - occurred.

EFAULT

An interface with side effects failed in some way - not directly related to mallctl*() - read/write processing.

-

The malloc_usable_size() function - returns the usable size of the allocation pointed to by - ptr.

ENVIRONMENT

The following environment variable affects the execution of the - allocation functions: -

MALLOC_CONF

If the environment variable - MALLOC_CONF is set, the characters it contains - will be interpreted as options.

-

The allocated - space is suitably aligned (after possible pointer coercion) for storage - of any type of object. - - The calloc function allocates - space for number objects, each - size bytes in length. The result is identical to - calling malloc with an argument of - number * size, with the - exception that the allocated memory is explicitly initialized to zero - bytes. - - The posix_memalign function - allocates size bytes of memory such that the - allocation's base address is a multiple of - alignment, and returns the allocation in the value - pointed to by ptr. The requested - alignment must be a power of 2 at least as large as - sizeof(void *). - - The aligned_alloc function - allocates size bytes of memory such that the - allocation's base address is a multiple of - alignment. The requested - alignment must be a power of 2. Behavior is - undefined if size is not an integral multiple of - alignment. - - The realloc function changes the - size of the previously allocated memory referenced by - ptr to size bytes. The - contents of the memory are unchanged up to the lesser of the new and old - sizes. If the new size is larger, the contents of the newly allocated - portion of the memory are undefined. Upon success, the memory referenced - by ptr is freed and a pointer to the newly - allocated memory is returned. Note that - realloc may move the memory allocation, - resulting in a different return value than ptr. - If ptr is NULL, the - realloc function behaves identically to - malloc for the specified size. - - The free function causes the - allocated memory referenced by ptr to be made - available for future allocations. If ptr is - NULL, no action occurs. - - - Non-standard API - The mallocx, - rallocx, - xallocx, - sallocx, - dallocx, - sdallocx, and - nallocx functions all have a - flags argument that can be used to specify - options. The functions only check the options that are contextually - relevant. Use bitwise or (|) operations to - specify one or more of the following: - - - MALLOCX_LG_ALIGN(la) - - - Align the memory allocation to start at an address - that is a multiple of (1 << - la). This macro does not validate - that la is within the valid - range. - - - MALLOCX_ALIGN(a) - - - Align the memory allocation to start at an address - that is a multiple of a, where - a is a power of two. This macro does not - validate that a is a power of 2. - - - - MALLOCX_ZERO - - Initialize newly allocated memory to contain zero - bytes. In the growing reallocation case, the real size prior to - reallocation defines the boundary between untouched bytes and those - that are initialized to contain zero bytes. If this macro is - absent, newly allocated memory is uninitialized. - - - MALLOCX_TCACHE(tc) - - - Use the thread-specific cache (tcache) specified by - the identifier tc, which must have been - acquired via the tcache.create - mallctl. This macro does not validate that - tc specifies a valid - identifier. - - - MALLOCX_TCACHE_NONE - - Do not use a thread-specific cache (tcache). Unless - MALLOCX_TCACHE(tc) or - MALLOCX_TCACHE_NONE is specified, an - automatically managed tcache will be used under many circumstances. - This macro cannot be used in the same flags - argument as - MALLOCX_TCACHE(tc). - - - MALLOCX_ARENA(a) - - - Use the arena specified by the index - a. This macro has no effect for regions that - were allocated via an arena other than the one specified. This - macro does not validate that a specifies an - arena index in the valid range. - - - - - The mallocx function allocates at - least size bytes of memory, and returns a pointer - to the base address of the allocation. Behavior is undefined if - size is 0, or if request size - overflows due to size class and/or alignment constraints. - - The rallocx function resizes the - allocation at ptr to be at least - size bytes, and returns a pointer to the base - address of the resulting allocation, which may or may not have moved from - its original location. Behavior is undefined if - size is 0, or if request size - overflows due to size class and/or alignment constraints. - - The xallocx function resizes the - allocation at ptr in place to be at least - size bytes, and returns the real size of the - allocation. If extra is non-zero, an attempt is - made to resize the allocation to be at least (size + - extra) bytes, though inability to allocate - the extra byte(s) will not by itself result in failure to resize. - Behavior is undefined if size is - 0, or if (size + extra - > SIZE_T_MAX). - - The sallocx function returns the - real size of the allocation at ptr. - - The dallocx function causes the - memory referenced by ptr to be made available for - future allocations. - - The sdallocx function is an - extension of dallocx with a - size parameter to allow the caller to pass in the - allocation size as an optimization. The minimum valid input size is the - original requested size of the allocation, and the maximum valid input - size is the corresponding value returned by - nallocx or - sallocx. - - The nallocx function allocates no - memory, but it performs the same size computation as the - mallocx function, and returns the real - size of the allocation that would result from the equivalent - mallocx function call. Behavior is - undefined if size is 0, or if - request size overflows due to size class and/or alignment - constraints. - - The mallctl function provides a - general interface for introspecting the memory allocator, as well as - setting modifiable parameters and triggering actions. The - period-separated name argument specifies a - location in a tree-structured namespace; see the section for - documentation on the tree contents. To read a value, pass a pointer via - oldp to adequate space to contain the value, and a - pointer to its length via oldlenp; otherwise pass - NULL and NULL. Similarly, to - write a value, pass a pointer to the value via - newp, and its length via - newlen; otherwise pass NULL - and 0. - - The mallctlnametomib function - provides a way to avoid repeated name lookups for applications that - repeatedly query the same portion of the namespace, by translating a name - to a “Management Information Base” (MIB) that can be passed - repeatedly to mallctlbymib. Upon - successful return from mallctlnametomib, - mibp contains an array of - *miblenp integers, where - *miblenp is the lesser of the number of components - in name and the input value of - *miblenp. Thus it is possible to pass a - *miblenp that is smaller than the number of - period-separated name components, which results in a partial MIB that can - be used as the basis for constructing a complete MIB. For name - components that are integers (e.g. the 2 in - arenas.bin.2.size), - the corresponding MIB component will always be that integer. Therefore, - it is legitimate to construct code like the following: - - The malloc_stats_print function - writes human-readable summary statistics via the - write_cb callback function pointer and - cbopaque data passed to - write_cb, or - malloc_message if - write_cb is NULL. This - function can be called repeatedly. General information that never - changes during execution can be omitted by specifying "g" as a character - within the opts string. Note that - malloc_message uses the - mallctl* functions internally, so - inconsistent statistics can be reported if multiple threads use these - functions simultaneously. If is - specified during configuration, “m” and “a” can - be specified to omit merged arena and per arena statistics, respectively; - “b”, “l”, and “h” can be specified to - omit per size class statistics for bins, large objects, and huge objects, - respectively. Unrecognized characters are silently ignored. Note that - thread caching may prevent some statistics from being completely up to - date, since extra locking would be required to merge counters that track - thread cache operations. - - - The malloc_usable_size function - returns the usable size of the allocation pointed to by - ptr. The return value may be larger than the size - that was requested during allocation. The - malloc_usable_size function is not a - mechanism for in-place realloc; rather - it is provided solely as a tool for introspection purposes. Any - discrepancy between the requested allocation size and the size reported - by malloc_usable_size should not be - depended on, since such behavior is entirely implementation-dependent. - - - - - TUNING - Once, when the first call is made to one of the memory allocation - routines, the allocator initializes its internals based in part on various - options that can be specified at compile- or run-time. - - The string pointed to by the global variable - malloc_conf, the “name” of the file - referenced by the symbolic link named /etc/malloc.conf, and the value of the - environment variable MALLOC_CONF, will be interpreted, in - that order, from left to right as options. Note that - malloc_conf may be read before - main is entered, so the declaration of - malloc_conf should specify an initializer that contains - the final value to be read by jemalloc. malloc_conf is - a compile-time setting, whereas /etc/malloc.conf and MALLOC_CONF - can be safely set any time prior to program invocation. - - An options string is a comma-separated list of option:value pairs. - There is one key corresponding to each opt.* mallctl (see the section for options - documentation). For example, abort:true,narenas:1 sets - the opt.abort and opt.narenas options. Some - options have boolean values (true/false), others have integer values (base - 8, 10, or 16, depending on prefix), and yet others have raw string - values. - - - IMPLEMENTATION NOTES - Traditionally, allocators have used - sbrk - 2 to obtain memory, which is - suboptimal for several reasons, including race conditions, increased - fragmentation, and artificial limitations on maximum usable memory. If - sbrk - 2 is supported by the operating - system, this allocator uses both - mmap - 2 and - sbrk - 2, in that order of preference; - otherwise only mmap - 2 is used. - - This allocator uses multiple arenas in order to reduce lock - contention for threaded programs on multi-processor systems. This works - well with regard to threading scalability, but incurs some costs. There is - a small fixed per-arena overhead, and additionally, arenas manage memory - completely independently of each other, which means a small fixed increase - in overall memory fragmentation. These overheads are not generally an - issue, given the number of arenas normally used. Note that using - substantially more arenas than the default is not likely to improve - performance, mainly due to reduced cache performance. However, it may make - sense to reduce the number of arenas if an application does not make much - use of the allocation functions. - - In addition to multiple arenas, unless - is specified during configuration, this - allocator supports thread-specific caching for small and large objects, in - order to make it possible to completely avoid synchronization for most - allocation requests. Such caching allows very fast allocation in the - common case, but it increases memory usage and fragmentation, since a - bounded number of objects can remain allocated in each thread cache. - - Memory is conceptually broken into equal-sized chunks, where the - chunk size is a power of two that is greater than the page size. Chunks - are always aligned to multiples of the chunk size. This alignment makes it - possible to find metadata for user objects very quickly. - - User objects are broken into three categories according to size: - small, large, and huge. Small and large objects are managed entirely by - arenas; huge objects are additionally aggregated in a single data structure - that is shared by all threads. Huge objects are typically used by - applications infrequently enough that this single data structure is not a - scalability issue. - - Each chunk that is managed by an arena tracks its contents as runs of - contiguous pages (unused, backing a set of small objects, or backing one - large object). The combination of chunk alignment and chunk page maps - makes it possible to determine all metadata regarding small and large - allocations in constant time. - - Small objects are managed in groups by page runs. Each run maintains - a bitmap to track which regions are in use. Allocation requests that are no - more than half the quantum (8 or 16, depending on architecture) are rounded - up to the nearest power of two that is at least sizeof(double). All other object size - classes are multiples of the quantum, spaced such that there are four size - classes for each doubling in size, which limits internal fragmentation to - approximately 20% for all but the smallest size classes. Small size classes - are smaller than four times the page size, large size classes are smaller - than the chunk size (see the opt.lg_chunk option), and - huge size classes extend from the chunk size up to one size class less than - the full address space size. - - Allocations are packed tightly together, which can be an issue for - multi-threaded applications. If you need to assure that allocations do not - suffer from cacheline sharing, round your allocation requests up to the - nearest multiple of the cacheline size, or specify cacheline alignment when - allocating. - - The realloc, - rallocx, and - xallocx functions may resize allocations - without moving them under limited circumstances. Unlike the - *allocx API, the standard API does not - officially round up the usable size of an allocation to the nearest size - class, so technically it is necessary to call - realloc to grow e.g. a 9-byte allocation to - 16 bytes, or shrink a 16-byte allocation to 9 bytes. Growth and shrinkage - trivially succeeds in place as long as the pre-size and post-size both round - up to the same size class. No other API guarantees are made regarding - in-place resizing, but the current implementation also tries to resize large - and huge allocations in place, as long as the pre-size and post-size are - both large or both huge. In such cases shrinkage always succeeds for large - size classes, but for huge size classes the chunk allocator must support - splitting (see arena.<i>.chunk_hooks). - Growth only succeeds if the trailing memory is currently available, and - additionally for huge size classes the chunk allocator must support - merging. - - Assuming 2 MiB chunks, 4 KiB pages, and a 16-byte quantum on a - 64-bit system, the size classes in each category are as shown in . - - - Size classes - - - - - - - Category - Spacing - Size - - - - - Small - lg - [8] - - - 16 - [16, 32, 48, 64, 80, 96, 112, 128] - - - 32 - [160, 192, 224, 256] - - - 64 - [320, 384, 448, 512] - - - 128 - [640, 768, 896, 1024] - - - 256 - [1280, 1536, 1792, 2048] - - - 512 - [2560, 3072, 3584, 4096] - - - 1 KiB - [5 KiB, 6 KiB, 7 KiB, 8 KiB] - - - 2 KiB - [10 KiB, 12 KiB, 14 KiB] - - - Large - 2 KiB - [16 KiB] - - - 4 KiB - [20 KiB, 24 KiB, 28 KiB, 32 KiB] - - - 8 KiB - [40 KiB, 48 KiB, 54 KiB, 64 KiB] - - - 16 KiB - [80 KiB, 96 KiB, 112 KiB, 128 KiB] - - - 32 KiB - [160 KiB, 192 KiB, 224 KiB, 256 KiB] - - - 64 KiB - [320 KiB, 384 KiB, 448 KiB, 512 KiB] - - - 128 KiB - [640 KiB, 768 KiB, 896 KiB, 1 MiB] - - - 256 KiB - [1280 KiB, 1536 KiB, 1792 KiB] - - - Huge - 256 KiB - [2 MiB] - - - 512 KiB - [2560 KiB, 3 MiB, 3584 KiB, 4 MiB] - - - 1 MiB - [5 MiB, 6 MiB, 7 MiB, 8 MiB] - - - 2 MiB - [10 MiB, 12 MiB, 14 MiB, 16 MiB] - - - 4 MiB - [20 MiB, 24 MiB, 28 MiB, 32 MiB] - - - 8 MiB - [40 MiB, 48 MiB, 56 MiB, 64 MiB] - - - ... - ... - - - -

If - enabled, the malloc_stats_print - function is called at program exit via an - atexit - 3 function. If - is specified during configuration, this - has the potential to cause deadlock for a multi-threaded process that - exits while one or more threads are executing in the memory allocation - functions. Furthermore, atexit may - allocate memory during application initialization and then deadlock - internally when jemalloc in turn calls - atexit, so this option is not - univerally usable (though the application can register its own - atexit function with equivalent - functionality). Therefore, this option should only be used with care; - it is primarily intended as a performance tuning aid during application - development. This option is disabled by default. - - - - - opt.junk - (const char *) - r- - [] - - Junk filling. If set to "alloc", each byte of - uninitialized allocated memory will be initialized to - 0xa5. If set to "free", all deallocated memory will - be initialized to 0x5a. If set to "true", both - allocated and deallocated memory will be initialized, and if set to - "false", junk filling be disabled entirely. This is intended for - debugging and will impact performance negatively. This option is - "false" by default unless is specified - during configuration, in which case it is "true" by default unless - running inside Valgrind. - - - - - opt.quarantine - (size_t) - r- - [] - - Per thread quarantine size in bytes. If non-zero, each - thread maintains a FIFO object quarantine that stores up to the - specified number of bytes of memory. The quarantined memory is not - freed until it is released from quarantine, though it is immediately - junk-filled if the opt.junk option is - enabled. This feature is of particular use in combination with Valgrind, which can detect attempts - to access quarantined objects. This is intended for debugging and will - impact performance negatively. The default quarantine size is 0 unless - running inside Valgrind, in which case the default is 16 - MiB. - - - - - opt.redzone - (bool) - r- - [] - - Redzones enabled/disabled. If enabled, small - allocations have redzones before and after them. Furthermore, if the - opt.junk option is - enabled, the redzones are checked for corruption during deallocation. - However, the primary intended purpose of this feature is to be used in - combination with Valgrind, - which needs redzones in order to do effective buffer overflow/underflow - detection. This option is intended for debugging and will impact - performance negatively. This option is disabled by - default unless running inside Valgrind. - - - - - opt.zero - (bool) - r- - [] - - Zero filling enabled/disabled. If enabled, each byte - of uninitialized allocated memory will be initialized to 0. Note that - this initialization only happens once for each byte, so - realloc and - rallocx calls do not zero memory that - was previously allocated.

This option is enabled by default. - - - - - opt.lg_prof_sample - (size_t) - r- - [] - - Average interval (log base 2) between allocation - samples, as measured in bytes of allocation activity. Increasing the - sampling interval decreases profile fidelity, but also decreases the - computational overhead. The default sample interval is 512 KiB (2^19 - B). - - - - - opt.prof_accum - (bool) - r- - [] - - Reporting of cumulative object/byte counts in profile - dumps enabled/disabled. If this option is enabled, every unique - backtrace must be stored for the duration of execution. Depending on - the application, this can impose a large memory overhead, and the - cumulative counts are not always of interest. This option is disabled - by default. - - - - - opt.lg_prof_interval - (ssize_t) - r- - [] - - Average interval (log base 2) between memory profile - dumps, as measured in bytes of allocation activity. The actual - interval between dumps may be sporadic because decentralized allocation - counters are used to avoid synchronization bottlenecks. Profiles are - dumped to files named according to the pattern - <prefix>.<pid>.<seq>.i<iseq>.heap, - where <prefix> is controlled by the - opt.prof_prefix - option. By default, interval-triggered profile dumping is disabled - (encoded as -1). - - - - - - opt.prof_gdump - (bool) - r- - [] - - Set the initial state of prof.gdump, which when - enabled triggers a memory profile dump every time the total virtual - memory exceeds the previous maximum.

Note that atexit may allocate - memory during application initialization and then deadlock internally - when jemalloc in turn calls atexit, so - this option is not univerally usable (though the application can - register its own atexit function with - equivalent functionality). This option is disabled by - default. - - - - - opt.prof_leak - (bool) - r- - [] - - Leak reporting enabled/disabled.

The tcache is - implicitly flushed as a side effect of becoming - disabled (see thread.tcache.flush). - - - - - - thread.tcache.flush - (void) - -- - [] - - Flush calling thread's thread-specific cache (tcache). - This interface releases all cached objects and internal data structures - associated with the calling thread's tcache. Ordinarily, this interface - need not be called, since automatic periodic incremental garbage - collection occurs, and the thread cache is automatically discarded when - a thread exits. However, garbage collection is triggered by allocation - activity, so it is possible for a thread that stops - allocating/deallocating to retain its cache indefinitely, in which case - the developer may find manual flushing useful. - - - - - thread.prof.name - (const char *) - r- or - -w - [] - - Get/set the descriptive name associated with the calling - thread in memory profile dumps. An internal copy of the name string is - created, so the input string need not be maintained after this interface - completes execution. The output string of this interface should be - copied for non-ephemeral uses, because multiple implementation details - can cause asynchronous string deallocation. Furthermore, each - invocation of this interface can only read or write; simultaneous - read/write is not supported due to string lifetime limitations.

The functions must be capable of operating on all extant - chunks associated with arena <i>, usually by passing unknown - chunks to the replaced functions. In practice, it is feasible to - control allocation for arenas created via arenas.extend such - that all chunks originate from an application-supplied chunk allocator - (by setting custom chunk hook functions just after arena creation), but - the automatically created arenas may have already created chunks prior - to the application having an opportunity to take over chunk - allocation. - - - The chunk_hooks_t structure comprises function - pointers which are described individually below. jemalloc uses these - functions to manage chunk lifetime, which starts off with allocation of - mapped committed memory, in the simplest case followed by deallocation. - However, there are performance and platform reasons to retain chunks for - later reuse. Cleanup attempts cascade from deallocation to decommit to - purging, which gives the chunk management functions opportunities to - reject the most permanent cleanup operations in favor of less permanent - (and often less costly) operations. The chunk splitting and merging - operations can also be opted out of, but this is mainly intended to - support platforms on which virtual memory mappings provided by the - operating system kernel do not automatically coalesce and split, e.g. - Windows. - - - typedef void *(chunk_alloc_t) - void *chunk - size_t size - size_t alignment - bool *zero - bool *commit - unsigned arena_ind - - - A chunk allocation function conforms to the - chunk_alloc_t type and upon success returns a pointer to - size bytes of mapped memory on behalf of arena - arena_ind such that the chunk's base address is a - multiple of alignment, as well as setting - *zero to indicate whether the chunk is zeroed and - *commit to indicate whether the chunk is - committed.

When so configured, jemalloc incorporates a wide variety - of run-time assertions that catch application errors such as double-free, - write-after-free, etc. - - Programs often accidentally depend on “uninitialized” - memory actually being filled with zero bytes. Junk filling - (see the opt.junk - option) tends to expose such bugs in the form of obviously incorrect - results and/or coredumps. Conversely, zero - filling (see the opt.zero option) eliminates - the symptoms of such bugs. Between these two options, it is usually - possible to quickly detect, diagnose, and eliminate such bugs. - - This implementation does not provide much detail about the problems - it detects, because the performance impact for storing such information - would be prohibitive. However, jemalloc does integrate with the most - excellent Valgrind tool if the - configuration option is enabled. - - - DIAGNOSTIC MESSAGES - If any of the memory allocation/deallocation functions detect an - error or warning condition, a message will be printed to file descriptor - STDERR_FILENO. Errors will result in the process - dumping core. If the opt.abort option is set, most - warnings are treated as errors. - - The malloc_message variable allows the programmer - to override the function which emits the text strings forming the errors - and warnings if for some reason the STDERR_FILENO file - descriptor is not suitable for this. - malloc_message takes the - cbopaque pointer argument that is - NULL unless overridden by the arguments in a call to - malloc_stats_print, followed by a string - pointer. Please note that doing anything which tries to allocate memory in - this function is likely to result in a crash or deadlock. - - All messages are prefixed by - “<jemalloc>: ”. - - - RETURN VALUES - - Standard API - The malloc and - calloc functions return a pointer to the - allocated memory if successful; otherwise a NULL - pointer is returned and errno is set to - ENOMEM. - - The posix_memalign function - returns the value 0 if successful; otherwise it returns an error value. - The posix_memalign function will fail - if: - - - EINVAL - - The alignment parameter is - not a power of 2 at least as large as - sizeof(void *). - - - - ENOMEM - - Memory allocation error. - - - - - The aligned_alloc function returns - a pointer to the allocated memory if successful; otherwise a - NULL pointer is returned and - errno is set. The - aligned_alloc function will fail if: - - - EINVAL - - The alignment parameter is - not a power of 2. - - - - ENOMEM - - Memory allocation error. - - - - - The realloc function returns a - pointer, possibly identical to ptr, to the - allocated memory if successful; otherwise a NULL - pointer is returned, and errno is set to - ENOMEM if the error was the result of an - allocation failure. The realloc - function always leaves the original buffer intact when an error occurs. - - - The free function returns no - value. - - - Non-standard API - The mallocx and - rallocx functions return a pointer to - the allocated memory if successful; otherwise a NULL - pointer is returned to indicate insufficient contiguous memory was - available to service the allocation request. - - The xallocx function returns the - real size of the resulting resized allocation pointed to by - ptr, which is a value less than - size if the allocation could not be adequately - grown in place. - - The sallocx function returns the - real size of the allocation pointed to by ptr. - - - The nallocx returns the real size - that would result from a successful equivalent - mallocx function call, or zero if - insufficient memory is available to perform the size computation. - - The mallctl, - mallctlnametomib, and - mallctlbymib functions return 0 on - success; otherwise they return an error value. The functions will fail - if: - - - EINVAL - - newp is not - NULL, and newlen is too - large or too small.

Instead of retyping almost the same stuff again and again it's just much better to hit the up arrow and edit on syntax errors, or in order to try a slightly different command. But apparently code dealing with terminals is some sort of Black Magic: readline is 30k lines of code, libedit 20k. Is it reasonable to link small utilities to huge libraries just to get a minimal support for line editing? - -So what usually happens is either: - - * Large programs with configure scripts disabling line editing if readline is not present in the system, or not supporting it at all since readline is GPL licensed and libedit (the BSD clone) is not as known and available as readline is (Real world example of this problem: Tclsh). - * Smaller programs not using a configure script not supporting line editing at all (A problem we had with Redis-cli for instance). - -The result is a pollution of binaries without line editing support. - -So I spent more or less two hours doing a reality check resulting in this little library: is it *really* needed for a line editing library to be 20k lines of code? Apparently not, it is possibe to get a very small, zero configuration, trivial to embed library, that solves the problem. Smaller programs will just include this, supporing line editing out of the box.

Here is a list of API calls -and how to use them. - - char *linenoise(const char *prompt); - -This is the main Linenoise call: it shows the user a prompt with line editing -and history capabilities. The prompt you specify is used as a prompt, that is, -it will be printed to the left of the cursor. The library returns a buffer -with the line composed by the user, or NULL on end of file or when there -is an out of memory condition. - -When a tty is detected (the user is actually typing into a terminal session) -the maximum editable line length is `LINENOISE_MAX_LINE`. When instead the -standard input is not a tty, which happens every time you redirect a file -to a program, or use it in an Unix pipeline, there are no limits to the -length of the line that can be returned. - -The returned line should be freed with the `free()` standard system call. -However sometimes it could happen that your program uses a different dynamic -allocation library, so you may also used `linenoiseFree` to make sure the -line is freed with the same allocator it was created. - -The canonical loop used by a program using Linenoise will be something like -this: - - while((line = linenoise("hello> ")) != NULL) { - printf("You wrote: %s\n", line); - linenoiseFree(line); /* Or just free(line) if you use libc malloc. */ - } - -## Single line VS multi line editing - -By default, Linenoise uses single line editing, that is, a single row on the -screen will be used, and as the user types more, the text will scroll towards -left to make room. This works if your program is one where the user is -unlikely to write a lot of text, otherwise multi line editing, where multiple -screens rows are used, can be a lot more comfortable. - -In order to enable multi line editing use the following API call: - - linenoiseSetMultiLine(1); - -You can disable it using `0` as argument. - -## History - -Linenoise supporst history, so that the user does not have to retype -again and again the same things, but can use the down and up arrows in order -to search and re-edit already inserted lines of text. - -The followings are the history API calls: - - int linenoiseHistoryAdd(const char *line); - int linenoiseHistorySetMaxLen(int len); - int linenoiseHistorySave(const char *filename); - int linenoiseHistoryLoad(const char *filename); - -Use `linenoiseHistoryAdd` every time you want to add a new element -to the top of the history (it will be the first the user will see when -using the up arrow). - -Note that for history to work, you have to set a length for the history -(which is zero by default, so history will be disabled if you don't set -a proper one). This is accomplished using the `linenoiseHistorySetMaxLen` -function. - -Linenoise has direct support for persisting the history into an history -file. The functions `linenoiseHistorySave` and `linenoiseHistoryLoad` do -just that. Both functions return -1 on error and 0 on success. - -## Completion - -Linenoise supports completion, which is the ability to complete the user -input when she or he presses the `` key. - -In order to use completion, you need to register a completion callback, which -is called every time the user presses ``. Your callback will return a -list of items that are completions for the current string. - -The following is an example of registering a completion callback: - - linenoiseSetCompletionCallback(completion); - -The completion must be a function returning `void` and getting as input -a `const char` pointer, which is the line the user has typed so far, and -a `linenoiseCompletions` object pointer, which is used as argument of -`linenoiseAddCompletion` in order to add completions inside the callback. -An example will make it more clear: - - void completion(const char *buf, linenoiseCompletions *lc) { - if (buf[0] == 'h') { - linenoiseAddCompletion(lc,"hello"); - linenoiseAddCompletion(lc,"hello there"); - } - } - -Basically in your completion callback, you inspect the input, and return -a list of items that are good completions by using `linenoiseAddCompletion`. - -If you want to test the completion feature, compile the example program -with `make`, run it, type `h` and press ``. - -## Hints - -Linenoise has a feature called *hints* which is very useful when you -use Linenoise in order to implement a REPL (Read Eval Print Loop) for -a program that accepts commands and arguments, but may also be useful in -other conditions. - -The feature shows, on the right of the cursor, as the user types, hints that -may be useful. The hints can be displayed using a different color compared -to the color the user is typing, and can also be bold. - -For example as the user starts to type `"git remote add"`, with hints it's -possible to show on the right of the prompt a string ` `. - -The feature works similarly to the history feature, using a callback. -To register the callback we use: - - linenoiseSetHintsCallback(hints); - -The callback itself is implemented like this: - - char *hints(const char *buf, int *color, int *bold) { - if (!strcasecmp(buf,"git remote add")) { - *color = 35; - *bold = 0; - return " "; - } - return NULL; - } - -The callback function returns the string that should be displayed or NULL -if no hint is available for the text the user currently typed. The returned -string will be trimmed as needed depending on the number of columns available -on the screen. - -It is possible to return a string allocated in dynamic way, by also registering -a function to deallocate the hint string once used: - - void linenoiseSetFreeHintsCallback(linenoiseFreeHintsCallback *); - -The free hint callback will just receive the pointer and free the string -as needed (depending on how the hits callback allocated it). - -As you can see in the example above, a `color` (in xterm color terminal codes) -can be provided together with a `bold` attribute. If no color is set, the -current terminal foreground color is used. If no bold attribute is set, -non-bold text is printed. - -Color codes are: - - red = 31 - green = 32 - yellow = 33 - blue = 34 - magenta = 35 - cyan = 36 - white = 37; - -## Screen handling - -Sometimes you may want to clear the screen as a result of something the -user typed.

NAME

-lua - Lua interpreter -

SYNOPSIS

-lua -[ -options -] -[ -script -[ -args -] -] -

DESCRIPTION

-lua -is the stand-alone Lua interpreter. -It loads and executes Lua programs, -either in textual source form or -in precompiled binary form. -(Precompiled binaries are output by -luac, -the Lua compiler.) -lua -can be used as a batch interpreter and also interactively. -

-The given -options -(see below) -are executed and then -the Lua program in file -script -is loaded and executed. -The given -args -are available to -script -as strings in a global table named -arg. -If these arguments contain spaces or other characters special to the shell, -then they should be quoted -(but note that the quotes will be removed by the shell). -The arguments in -arg -start at 0, -which contains the string -'script'. -The index of the last argument is stored in -arg.n. -The arguments given in the command line before -script, -including the name of the interpreter, -are available in negative indices in -arg. -

-At the very start, -before even handling the command line, -lua -executes the contents of the environment variable -LUA_INIT, -if it is defined. -If the value of -LUA_INIT -is of the form -'@filename', -then -filename -is executed. -Otherwise, the string is assumed to be a Lua statement and is executed. -

-Options start with -'-' -and are described below. -You can use -'--' -to signal the end of options. -

-If no arguments are given, -then -"-v -i" -is assumed when the standard input is a terminal; -otherwise, -"-" -is assumed. -

-In interactive mode, -lua -prompts the user, -reads lines from the standard input, -and executes them as they are read. -If a line does not contain a complete statement, -then a secondary prompt is displayed and -lines are read until a complete statement is formed or -a syntax error is found. -So, one way to interrupt the reading of an incomplete statement is -to force a syntax error: -adding a -';' -in the middle of a statement is a sure way of forcing a syntax error -(except inside multiline strings and comments; these must be closed explicitly). -If a line starts with -'=', -then -lua -displays the values of all the expressions in the remainder of the -line. The expressions must be separated by commas. -The primary prompt is the value of the global variable -_PROMPT, -if this value is a string; -otherwise, the default prompt is used. -Similarly, the secondary prompt is the value of the global variable -_PROMPT2. -So, -to change the prompts, -set the corresponding variable to a string of your choice. -You can do that after calling the interpreter -or on the command line -(but in this case you have to be careful with quotes -if the prompt string contains a space; otherwise you may confuse the shell.) -The default prompts are "> " and ">> ". -

OPTIONS

-

-- -load and execute the standard input as a file, -that is, -not interactively, -even when the standard input is a terminal. -

--e stat -execute statement -stat. -You need to quote -stat -if it contains spaces, quotes, -or other characters special to the shell. -

--i -enter interactive mode after -script -is executed. -

--l name -call -require('name') -before executing -script. -Typically used to load libraries. -

--v -show version information. -

NAME

-luac - Lua compiler -

SYNOPSIS

-luac -[ -options -] [ -filenames -] -

DESCRIPTION

-luac -is the Lua compiler. -It translates programs written in the Lua programming language -into binary files that can be later loaded and executed. -

-The main advantages of precompiling chunks are: -faster loading, -protecting source code from accidental user changes, -and -off-line syntax checking. -

-Precompiling does not imply faster execution -because in Lua chunks are always compiled into bytecodes before being executed. -luac -simply allows those bytecodes to be saved in a file for later execution. -

-Precompiled chunks are not necessarily smaller than the corresponding source. -The main goal in precompiling is faster loading. -

-The binary files created by -luac -are portable only among architectures with the same word size and byte order. -

-luac -produces a single output file containing the bytecodes -for all source files given. -By default, -the output file is named -luac.out, -but you can change this with the --o -option. -

-In the command line, -you can mix -text files containing Lua source and -binary files containing precompiled chunks. -This is useful because several precompiled chunks, -even from different (but compatible) platforms, -can be combined into a single precompiled chunk. -

-You can use -'-' -to indicate the standard input as a source file -and -'--' -to signal the end of options -(that is, -all remaining arguments will be treated as files even if they start with -'-'). -

-The internal format of the binary files produced by -luac -is likely to change when a new version of Lua is released. -So, -save the source files of all Lua programs that you precompile. -

-

OPTIONS

-Options must be separate. -

--l -produce a listing of the compiled bytecode for Lua's virtual machine. -Listing bytecodes is useful to learn about Lua's virtual machine. -If no files are given, then -luac -loads -luac.out -and lists its contents. -

--o file -output to -file, -instead of the default -luac.out. -(You can use -'-' -for standard output, -but not on platforms that open standard output in text mode.) -The output file may be a source file because -all files are loaded before the output file is written. -Be careful not to overwrite precious files. -

--p -load files but do not generate any output file. -Used mainly for syntax checking and for testing precompiled chunks: -corrupted files will probably generate errors when loaded. -Lua always performs a thorough integrity test on precompiled chunks. -Bytecode that passes this test is completely safe, -in the sense that it will not break the interpreter. -However, -there is no guarantee that such code does anything sensible. -(None can be given, because the halting problem is unsolvable.) -If no files are given, then -luac -loads -luac.out -and tests its contents. -No messages are displayed if the file passes the integrity test. -

--s -strip debug information before writing the output file. -This saves some space in very large chunks, -but if errors occur when running a stripped chunk, -then the error messages may not contain the full information they usually do. -For instance, -line numbers and names of local variables are lost. -

--v -show version information. -

1 - Introduction

- -

-Lua is an extension programming language designed to support -general procedural programming with data description -facilities. -It also offers good support for object-oriented programming, -functional programming, and data-driven programming. -Lua is intended to be used as a powerful, light-weight -scripting language for any program that needs one. -Lua is implemented as a library, written in clean C -(that is, in the common subset of ANSI C and C++). - - -

-Being an extension language, Lua has no notion of a "main" program: -it only works embedded in a host client, -called the embedding program or simply the host. -This host program can invoke functions to execute a piece of Lua code, -can write and read Lua variables, -and can register C functions to be called by Lua code. -Through the use of C functions, Lua can be augmented to cope with -a wide range of different domains, -thus creating customized programming languages sharing a syntactical framework. -The Lua distribution includes a sample host program called lua, -which uses the Lua library to offer a complete, stand-alone Lua interpreter. - - -

-Lua is free software, -and is provided as usual with no guarantees, -as stated in its license. -The implementation described in this manual is available -at Lua's official web site, www.lua.org. - - -

-Like any other reference manual, -this document is dry in places. -For a discussion of the decisions behind the design of Lua, -see the technical papers available at Lua's web site. -For a detailed introduction to programming in Lua, -see Roberto's book, Programming in Lua (Second Edition). - - - -

2 - The Language

- -

-This section describes the lexis, the syntax, and the semantics of Lua. -In other words, -this section describes -which tokens are valid, -how they can be combined, -and what their combinations mean. - - -

-The language constructs will be explained using the usual extended BNF notation, -in which -{a} means 0 or more a's, and -[a] means an optional a. -Non-terminals are shown like non-terminal, -keywords are shown like kword, -and other terminal symbols are shown like `=´. -The complete syntax of Lua can be found in §8 -at the end of this manual. - - - -

2.1 - Lexical Conventions

- -

-Names -(also called identifiers) -in Lua can be any string of letters, -digits, and underscores, -not beginning with a digit. -This coincides with the definition of names in most languages. -(The definition of letter depends on the current locale: -any character considered alphabetic by the current locale -can be used in an identifier.) -Identifiers are used to name variables and table fields. - - -

-The following keywords are reserved -and cannot be used as names: - - -

-     and       break     do        else      elseif
-     end       false     for       function  if
-     in        local     nil       not       or
-     repeat    return    then      true      until     while
-
- -

-Lua is a case-sensitive language: -and is a reserved word, but And and AND -are two different, valid names. -As a convention, names starting with an underscore followed by -uppercase letters (such as _VERSION) -are reserved for internal global variables used by Lua. - - -

-The following strings denote other tokens: - -

-     +     -     *     /     %     ^     #
-     ==    ~=    <=    >=    <     >     =
-     (     )     {     }     [     ]
-     ;     :     ,     .     ..    ...
-
- -

-Literal strings -can be delimited by matching single or double quotes, -and can contain the following C-like escape sequences: -'\a' (bell), -'\b' (backspace), -'\f' (form feed), -'\n' (newline), -'\r' (carriage return), -'\t' (horizontal tab), -'\v' (vertical tab), -'\\' (backslash), -'\"' (quotation mark [double quote]), -and '\'' (apostrophe [single quote]). -Moreover, a backslash followed by a real newline -results in a newline in the string. -A character in a string can also be specified by its numerical value -using the escape sequence \ddd, -where ddd is a sequence of up to three decimal digits. -(Note that if a numerical escape is to be followed by a digit, -it must be expressed using exactly three digits.) -Strings in Lua can contain any 8-bit value, including embedded zeros, -which can be specified as '\0'. - - -

-Literal strings can also be defined using a long format -enclosed by long brackets. -We define an opening long bracket of level n as an opening -square bracket followed by n equal signs followed by another -opening square bracket. -So, an opening long bracket of level 0 is written as [[, -an opening long bracket of level 1 is written as [=[, -and so on. -A closing long bracket is defined similarly; -for instance, a closing long bracket of level 4 is written as ]====]. -A long string starts with an opening long bracket of any level and -ends at the first closing long bracket of the same level. -Literals in this bracketed form can run for several lines, -do not interpret any escape sequences, -and ignore long brackets of any other level. -They can contain anything except a closing bracket of the proper level. - - -

-For convenience, -when the opening long bracket is immediately followed by a newline, -the newline is not included in the string. -As an example, in a system using ASCII -(in which 'a' is coded as 97, -newline is coded as 10, and '1' is coded as 49), -the five literal strings below denote the same string: - -

-     a = 'alo\n123"'
-     a = "alo\n123\""
-     a = '\97lo\10\04923"'
-     a = [[alo
-     123"]]
-     a = [==[
-     alo
-     123"]==]
-
- -

-A numerical constant can be written with an optional decimal part -and an optional decimal exponent. -Lua also accepts integer hexadecimal constants, -by prefixing them with 0x. -Examples of valid numerical constants are - -

-     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56
-
- -

-A comment starts with a double hyphen (--) -anywhere outside a string. -If the text immediately after -- is not an opening long bracket, -the comment is a short comment, -which runs until the end of the line. -Otherwise, it is a long comment, -which runs until the corresponding closing long bracket. -Long comments are frequently used to disable code temporarily. - - - - - -

2.2 - Values and Types

- -

-Lua is a dynamically typed language. -This means that -variables do not have types; only values do. -There are no type definitions in the language. -All values carry their own type. - - -

-All values in Lua are first-class values. -This means that all values can be stored in variables, -passed as arguments to other functions, and returned as results. - - -

-There are eight basic types in Lua: -nil, boolean, number, -string, function, userdata, -thread, and table. -Nil is the type of the value nil, -whose main property is to be different from any other value; -it usually represents the absence of a useful value. -Boolean is the type of the values false and true. -Both nil and false make a condition false; -any other value makes it true. -Number represents real (double-precision floating-point) numbers. -(It is easy to build Lua interpreters that use other -internal representations for numbers, -such as single-precision float or long integers; -see file luaconf.h.) -String represents arrays of characters. - -Lua is 8-bit clean: -strings can contain any 8-bit character, -including embedded zeros ('\0') (see §2.1). - - -

-Lua can call (and manipulate) functions written in Lua and -functions written in C -(see §2.5.8). - - -

-The type userdata is provided to allow arbitrary C data to -be stored in Lua variables. -This type corresponds to a block of raw memory -and has no pre-defined operations in Lua, -except assignment and identity test. -However, by using metatables, -the programmer can define operations for userdata values -(see §2.8). -Userdata values cannot be created or modified in Lua, -only through the C API. -This guarantees the integrity of data owned by the host program. - - -

-The type thread represents independent threads of execution -and it is used to implement coroutines (see §2.11). -Do not confuse Lua threads with operating-system threads. -Lua supports coroutines on all systems, -even those that do not support threads. - - -

-The type table implements associative arrays, -that is, arrays that can be indexed not only with numbers, -but with any value (except nil). -Tables can be heterogeneous; -that is, they can contain values of all types (except nil). -Tables are the sole data structuring mechanism in Lua; -they can be used to represent ordinary arrays, -symbol tables, sets, records, graphs, trees, etc. -To represent records, Lua uses the field name as an index. -The language supports this representation by -providing a.name as syntactic sugar for a["name"]. -There are several convenient ways to create tables in Lua -(see §2.5.7). - - -

-Like indices, -the value of a table field can be of any type (except nil). -In particular, -because functions are first-class values, -table fields can contain functions. -Thus tables can also carry methods (see §2.5.9). - - -

-Tables, functions, threads, and (full) userdata values are objects: -variables do not actually contain these values, -only references to them. -Assignment, parameter passing, and function returns -always manipulate references to such values; -these operations do not imply any kind of copy. - - -

-The library function type returns a string describing the type -of a given value. - - - -

2.2.1 - Coercion

- -

-Lua provides automatic conversion between -string and number values at run time. -Any arithmetic operation applied to a string tries to convert -this string to a number, following the usual conversion rules. -Conversely, whenever a number is used where a string is expected, -the number is converted to a string, in a reasonable format. -For complete control over how numbers are converted to strings, -use the format function from the string library -(see string.format). - - - - - - - -

2.3 - Variables

- -

-Variables are places that store values. - -There are three kinds of variables in Lua: -global variables, local variables, and table fields. - - -

-A single name can denote a global variable or a local variable -(or a function's formal parameter, -which is a particular kind of local variable): - -

-	var ::= Name
-

-Name denotes identifiers, as defined in §2.1. - - -

-Any variable is assumed to be global unless explicitly declared -as a local (see §2.4.7). -Local variables are lexically scoped: -local variables can be freely accessed by functions -defined inside their scope (see §2.6). - - -

-Before the first assignment to a variable, its value is nil. - - -

-Square brackets are used to index a table: - -

-	var ::= prefixexp `[´ exp `]´
-

-The meaning of accesses to global variables -and table fields can be changed via metatables. -An access to an indexed variable t[i] is equivalent to -a call gettable_event(t,i). -(See §2.8 for a complete description of the -gettable_event function. -This function is not defined or callable in Lua. -We use it here only for explanatory purposes.) - - -

-The syntax var.Name is just syntactic sugar for -var["Name"]: - -

-	var ::= prefixexp `.´ Name
-
- -

-All global variables live as fields in ordinary Lua tables, -called environment tables or simply -environments (see §2.9). -Each function has its own reference to an environment, -so that all global variables in this function -will refer to this environment table. -When a function is created, -it inherits the environment from the function that created it. -To get the environment table of a Lua function, -you call getfenv. -To replace it, -you call setfenv. -(You can only manipulate the environment of C functions -through the debug library; (see §5.9).) - - -

-An access to a global variable x -is equivalent to _env.x, -which in turn is equivalent to - -

-     gettable_event(_env, "x")
-

-where _env is the environment of the running function. -(See §2.8 for a complete description of the -gettable_event function. -This function is not defined or callable in Lua. -Similarly, the _env variable is not defined in Lua. -We use them here only for explanatory purposes.) - - - - - -

2.4 - Statements

- -

-Lua supports an almost conventional set of statements, -similar to those in Pascal or C. -This set includes -assignments, control structures, function calls, -and variable declarations. - - - -

2.4.1 - Chunks

- -

-The unit of execution of Lua is called a chunk. -A chunk is simply a sequence of statements, -which are executed sequentially. -Each statement can be optionally followed by a semicolon: - -

-	chunk ::= {stat [`;´]}
-

-There are no empty statements and thus ';;' is not legal. - - -

-Lua handles a chunk as the body of an anonymous function -with a variable number of arguments -(see §2.5.9). -As such, chunks can define local variables, -receive arguments, and return values. - - -

-A chunk can be stored in a file or in a string inside the host program. -To execute a chunk, -Lua first pre-compiles the chunk into instructions for a virtual machine, -and then it executes the compiled code -with an interpreter for the virtual machine. - - -

-Chunks can also be pre-compiled into binary form; -see program luac for details. -Programs in source and compiled forms are interchangeable; -Lua automatically detects the file type and acts accordingly. - - - - - - -

2.4.2 - Blocks

-A block is a list of statements; -syntactically, a block is the same as a chunk: - -

-	block ::= chunk
-
- -

-A block can be explicitly delimited to produce a single statement: - -

-	stat ::= do block end
-

-Explicit blocks are useful -to control the scope of variable declarations. -Explicit blocks are also sometimes used to -add a return or break statement in the middle -of another block (see §2.4.4). - - - - - -

2.4.3 - Assignment

- -

-Lua allows multiple assignments. -Therefore, the syntax for assignment -defines a list of variables on the left side -and a list of expressions on the right side. -The elements in both lists are separated by commas: - -

-	stat ::= varlist `=´ explist
-	varlist ::= var {`,´ var}
-	explist ::= exp {`,´ exp}
-

-Expressions are discussed in §2.5. - - -

-Before the assignment, -the list of values is adjusted to the length of -the list of variables. -If there are more values than needed, -the excess values are thrown away. -If there are fewer values than needed, -the list is extended with as many nil's as needed. -If the list of expressions ends with a function call, -then all values returned by that call enter the list of values, -before the adjustment -(except when the call is enclosed in parentheses; see §2.5). - - -

-The assignment statement first evaluates all its expressions -and only then are the assignments performed. -Thus the code - -

-     i = 3
-     i, a[i] = i+1, 20
-

-sets a[3] to 20, without affecting a[4] -because the i in a[i] is evaluated (to 3) -before it is assigned 4. -Similarly, the line - -

-     x, y = y, x
-

-exchanges the values of x and y, -and - -

-     x, y, z = y, z, x
-

-cyclically permutes the values of x, y, and z. - - -

-The meaning of assignments to global variables -and table fields can be changed via metatables. -An assignment to an indexed variable t[i] = val is equivalent to -settable_event(t,i,val). -(See §2.8 for a complete description of the -settable_event function. -This function is not defined or callable in Lua. -We use it here only for explanatory purposes.) - - -

-An assignment to a global variable x = val -is equivalent to the assignment -_env.x = val, -which in turn is equivalent to - -

-     settable_event(_env, "x", val)
-

-where _env is the environment of the running function. -(The _env variable is not defined in Lua. -We use it here only for explanatory purposes.) - - - - - -

2.4.4 - Control Structures

-The control structures -if, while, and repeat have the usual meaning and -familiar syntax: - - - - -

-	stat ::= while exp do block end
-	stat ::= repeat block until exp
-	stat ::= if exp then block {elseif exp then block} [else block] end
-

-Lua also has a for statement, in two flavors (see §2.4.5). - - -

-The condition expression of a -control structure can return any value. -Both false and nil are considered false. -All values different from nil and false are considered true -(in particular, the number 0 and the empty string are also true). - - -

-In the repeat–until loop, -the inner block does not end at the until keyword, -but only after the condition. -So, the condition can refer to local variables -declared inside the loop block. - - -

-The return statement is used to return values -from a function or a chunk (which is just a function). - -Functions and chunks can return more than one value, -and so the syntax for the return statement is - -

-	stat ::= return [explist]
-
- -

-The break statement is used to terminate the execution of a -while, repeat, or for loop, -skipping to the next statement after the loop: - - -

-	stat ::= break
-

-A break ends the innermost enclosing loop. - - -

-The return and break -statements can only be written as the last statement of a block. -If it is really necessary to return or break in the -middle of a block, -then an explicit inner block can be used, -as in the idioms -do return end and do break end, -because now return and break are the last statements in -their (inner) blocks. - - - - - -

2.4.5 - For Statement

- -

- -The for statement has two forms: -one numeric and one generic. - - -

-The numeric for loop repeats a block of code while a -control variable runs through an arithmetic progression. -It has the following syntax: - -

-	stat ::= for Name `=´ exp `,´ exp [`,´ exp] do block end
-

-The block is repeated for name starting at the value of -the first exp, until it passes the second exp by steps of the -third exp. -More precisely, a for statement like - -

-     for v = e1, e2, e3 do block end
-

-is equivalent to the code: - -

-     do
-       local var, limit, step = tonumber(e1), tonumber(e2), tonumber(e3)
-       if not (var and limit and step) then error() end
-       while (step > 0 and var <= limit) or (step <= 0 and var >= limit) do
-         local v = var
-         block
-         var = var + step
-       end
-     end
-

-Note the following: - -

    - -
  • -All three control expressions are evaluated only once, -before the loop starts. -They must all result in numbers. -
    • - -
  • -var, limit, and step are invisible variables. -The names shown here are for explanatory purposes only. -
    • - -
  • -If the third expression (the step) is absent, -then a step of 1 is used. -
    • - -
  • -You can use break to exit a for loop. -
    • - -
  • -The loop variable v is local to the loop; -you cannot use its value after the for ends or is broken. -If you need this value, -assign it to another variable before breaking or exiting the loop. -
    • - -
- -

-The generic for statement works over functions, -called iterators. -On each iteration, the iterator function is called to produce a new value, -stopping when this new value is nil. -The generic for loop has the following syntax: - -

-	stat ::= for namelist in explist do block end
-	namelist ::= Name {`,´ Name}
-

-A for statement like - -

-     for var_1, ···, var_n in explist do block end
-

-is equivalent to the code: - -

-     do
-       local f, s, var = explist
-       while true do
-         local var_1, ···, var_n = f(s, var)
-         var = var_1
-         if var == nil then break end
-         block
-       end
-     end
-

-Note the following: - -

    - -
  • -explist is evaluated only once. -Its results are an iterator function, -a state, -and an initial value for the first iterator variable. -
    • - -
  • -f, s, and var are invisible variables. -The names are here for explanatory purposes only. -
    • - -
  • -You can use break to exit a for loop. -
    • - -
  • -The loop variables var_i are local to the loop; -you cannot use their values after the for ends. -If you need these values, -then assign them to other variables before breaking or exiting the loop. -
    • - -
- - - - -

2.4.6 - Function Calls as Statements

-To allow possible side-effects, -function calls can be executed as statements: - -

-	stat ::= functioncall
-

-In this case, all returned values are thrown away. -Function calls are explained in §2.5.8. - - - - - -

2.4.7 - Local Declarations

-Local variables can be declared anywhere inside a block. -The declaration can include an initial assignment: - -

-	stat ::= local namelist [`=´ explist]
-

-If present, an initial assignment has the same semantics -of a multiple assignment (see §2.4.3). -Otherwise, all variables are initialized with nil. - - -

-A chunk is also a block (see §2.4.1), -and so local variables can be declared in a chunk outside any explicit block. -The scope of such local variables extends until the end of the chunk. - - -

-The visibility rules for local variables are explained in §2.6. - - - - - - - -

2.5 - Expressions

- -

-The basic expressions in Lua are the following: - -

-	exp ::= prefixexp
-	exp ::= nil | false | true
-	exp ::= Number
-	exp ::= String
-	exp ::= function
-	exp ::= tableconstructor
-	exp ::= `...´
-	exp ::= exp binop exp
-	exp ::= unop exp
-	prefixexp ::= var | functioncall | `(´ exp `)´
-
- -

-Numbers and literal strings are explained in §2.1; -variables are explained in §2.3; -function definitions are explained in §2.5.9; -function calls are explained in §2.5.8; -table constructors are explained in §2.5.7. -Vararg expressions, -denoted by three dots ('...'), can only be used when -directly inside a vararg function; -they are explained in §2.5.9. - - -

-Binary operators comprise arithmetic operators (see §2.5.1), -relational operators (see §2.5.2), logical operators (see §2.5.3), -and the concatenation operator (see §2.5.4). -Unary operators comprise the unary minus (see §2.5.1), -the unary not (see §2.5.3), -and the unary length operator (see §2.5.5). - - -

-Both function calls and vararg expressions can result in multiple values. -If an expression is used as a statement -(only possible for function calls (see §2.4.6)), -then its return list is adjusted to zero elements, -thus discarding all returned values. -If an expression is used as the last (or the only) element -of a list of expressions, -then no adjustment is made -(unless the call is enclosed in parentheses). -In all other contexts, -Lua adjusts the result list to one element, -discarding all values except the first one. - - -

-Here are some examples: - -

-     f()                -- adjusted to 0 results
-     g(f(), x)          -- f() is adjusted to 1 result
-     g(x, f())          -- g gets x plus all results from f()
-     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
-     a,b = ...          -- a gets the first vararg parameter, b gets
-                        -- the second (both a and b can get nil if there
-                        -- is no corresponding vararg parameter)
-     
-     a,b,c = x, f()     -- f() is adjusted to 2 results
-     a,b,c = f()        -- f() is adjusted to 3 results
-     return f()         -- returns all results from f()
-     return ...         -- returns all received vararg parameters
-     return x,y,f()     -- returns x, y, and all results from f()
-     {f()}              -- creates a list with all results from f()
-     {...}              -- creates a list with all vararg parameters
-     {f(), nil}         -- f() is adjusted to 1 result
-
- -

-Any expression enclosed in parentheses always results in only one value. -Thus, -(f(x,y,z)) is always a single value, -even if f returns several values. -(The value of (f(x,y,z)) is the first value returned by f -or nil if f does not return any values.) - - - -

2.5.1 - Arithmetic Operators

-Lua supports the usual arithmetic operators: -the binary + (addition), -- (subtraction), * (multiplication), -/ (division), % (modulo), and ^ (exponentiation); -and unary - (negation). -If the operands are numbers, or strings that can be converted to -numbers (see §2.2.1), -then all operations have the usual meaning. -Exponentiation works for any exponent. -For instance, x^(-0.5) computes the inverse of the square root of x. -Modulo is defined as - -

-     a % b == a - math.floor(a/b)*b
-

-That is, it is the remainder of a division that rounds -the quotient towards minus infinity. - - - - - -

2.5.2 - Relational Operators

-The relational operators in Lua are - -

-     ==    ~=    <     >     <=    >=
-

-These operators always result in false or true. - - -

-Equality (==) first compares the type of its operands. -If the types are different, then the result is false. -Otherwise, the values of the operands are compared. -Numbers and strings are compared in the usual way. -Objects (tables, userdata, threads, and functions) -are compared by reference: -two objects are considered equal only if they are the same object. -Every time you create a new object -(a table, userdata, thread, or function), -this new object is different from any previously existing object. - - -

-You can change the way that Lua compares tables and userdata -by using the "eq" metamethod (see §2.8). - - -

-The conversion rules of §2.2.1 -do not apply to equality comparisons. -Thus, "0"==0 evaluates to false, -and t[0] and t["0"] denote different -entries in a table. - - -

-The operator ~= is exactly the negation of equality (==). - - -

-The order operators work as follows. -If both arguments are numbers, then they are compared as such. -Otherwise, if both arguments are strings, -then their values are compared according to the current locale. -Otherwise, Lua tries to call the "lt" or the "le" -metamethod (see §2.8). -A comparison a > b is translated to b < a -and a >= b is translated to b <= a. - - - - - -

2.5.3 - Logical Operators

-The logical operators in Lua are -and, or, and not. -Like the control structures (see §2.4.4), -all logical operators consider both false and nil as false -and anything else as true. - - -

-The negation operator not always returns false or true. -The conjunction operator and returns its first argument -if this value is false or nil; -otherwise, and returns its second argument. -The disjunction operator or returns its first argument -if this value is different from nil and false; -otherwise, or returns its second argument. -Both and and or use short-cut evaluation; -that is, -the second operand is evaluated only if necessary. -Here are some examples: - -

-     10 or 20            --> 10
-     10 or error()       --> 10
-     nil or "a"          --> "a"
-     nil and 10          --> nil
-     false and error()   --> false
-     false and nil       --> false
-     false or nil        --> nil
-     10 and 20           --> 20
-

-(In this manual, ---> indicates the result of the preceding expression.) - - - - - -

2.5.4 - Concatenation

-The string concatenation operator in Lua is -denoted by two dots ('..'). -If both operands are strings or numbers, then they are converted to -strings according to the rules mentioned in §2.2.1. -Otherwise, the "concat" metamethod is called (see §2.8). - - - - - -

2.5.5 - The Length Operator

- -

-The length operator is denoted by the unary operator #. -The length of a string is its number of bytes -(that is, the usual meaning of string length when each -character is one byte). - - -

-The length of a table t is defined to be any -integer index n -such that t[n] is not nil and t[n+1] is nil; -moreover, if t[1] is nil, n can be zero. -For a regular array, with non-nil values from 1 to a given n, -its length is exactly that n, -the index of its last value. -If the array has "holes" -(that is, nil values between other non-nil values), -then #t can be any of the indices that -directly precedes a nil value -(that is, it may consider any such nil value as the end of -the array). - - - - - -

2.5.6 - Precedence

-Operator precedence in Lua follows the table below, -from lower to higher priority: - -

-     or
-     and
-     <     >     <=    >=    ~=    ==
-     ..
-     +     -
-     *     /     %
-     not   #     - (unary)
-     ^
-

-As usual, -you can use parentheses to change the precedences of an expression. -The concatenation ('..') and exponentiation ('^') -operators are right associative. -All other binary operators are left associative. - - - - - -

2.5.7 - Table Constructors

-Table constructors are expressions that create tables. -Every time a constructor is evaluated, a new table is created. -A constructor can be used to create an empty table -or to create a table and initialize some of its fields. -The general syntax for constructors is - -

-	tableconstructor ::= `{´ [fieldlist] `}´
-	fieldlist ::= field {fieldsep field} [fieldsep]
-	field ::= `[´ exp `]´ `=´ exp | Name `=´ exp | exp
-	fieldsep ::= `,´ | `;´
-
- -

-Each field of the form [exp1] = exp2 adds to the new table an entry -with key exp1 and value exp2. -A field of the form name = exp is equivalent to -["name"] = exp. -Finally, fields of the form exp are equivalent to -[i] = exp, where i are consecutive numerical integers, -starting with 1. -Fields in the other formats do not affect this counting. -For example, - -

-     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
-

-is equivalent to - -

-     do
-       local t = {}
-       t[f(1)] = g
-       t[1] = "x"         -- 1st exp
-       t[2] = "y"         -- 2nd exp
-       t.x = 1            -- t["x"] = 1
-       t[3] = f(x)        -- 3rd exp
-       t[30] = 23
-       t[4] = 45          -- 4th exp
-       a = t
-     end
-
- -

-If the last field in the list has the form exp -and the expression is a function call or a vararg expression, -then all values returned by this expression enter the list consecutively -(see §2.5.8). -To avoid this, -enclose the function call or the vararg expression -in parentheses (see §2.5). - - -

-The field list can have an optional trailing separator, -as a convenience for machine-generated code. - - - - - -

2.5.8 - Function Calls

-A function call in Lua has the following syntax: - -

-	functioncall ::= prefixexp args
-

-In a function call, -first prefixexp and args are evaluated. -If the value of prefixexp has type function, -then this function is called -with the given arguments. -Otherwise, the prefixexp "call" metamethod is called, -having as first parameter the value of prefixexp, -followed by the original call arguments -(see §2.8). - - -

-The form - -

-	functioncall ::= prefixexp `:´ Name args
-

-can be used to call "methods". -A call v:name(args) -is syntactic sugar for v.name(v,args), -except that v is evaluated only once. - - -

-Arguments have the following syntax: - -

-	args ::= `(´ [explist] `)´
-	args ::= tableconstructor
-	args ::= String
-

-All argument expressions are evaluated before the call. -A call of the form f{fields} is -syntactic sugar for f({fields}); -that is, the argument list is a single new table. -A call of the form f'string' -(or f"string" or f[[string]]) -is syntactic sugar for f('string'); -that is, the argument list is a single literal string. - - -

-As an exception to the free-format syntax of Lua, -you cannot put a line break before the '(' in a function call. -This restriction avoids some ambiguities in the language. -If you write - -

-     a = f
-     (g).x(a)
-

-Lua would see that as a single statement, a = f(g).x(a). -So, if you want two statements, you must add a semi-colon between them. -If you actually want to call f, -you must remove the line break before (g). - - -

-A call of the form return functioncall is called -a tail call. -Lua implements proper tail calls -(or proper tail recursion): -in a tail call, -the called function reuses the stack entry of the calling function. -Therefore, there is no limit on the number of nested tail calls that -a program can execute. -However, a tail call erases any debug information about the -calling function. -Note that a tail call only happens with a particular syntax, -where the return has one single function call as argument; -this syntax makes the calling function return exactly -the returns of the called function. -So, none of the following examples are tail calls: - -

-     return (f(x))        -- results adjusted to 1
-     return 2 * f(x)
-     return x, f(x)       -- additional results
-     f(x); return         -- results discarded
-     return x or f(x)     -- results adjusted to 1
-
- - - - -

2.5.9 - Function Definitions

- -

-The syntax for function definition is - -

-	function ::= function funcbody
-	funcbody ::= `(´ [parlist] `)´ block end
-
- -

-The following syntactic sugar simplifies function definitions: - -

-	stat ::= function funcname funcbody
-	stat ::= local function Name funcbody
-	funcname ::= Name {`.´ Name} [`:´ Name]
-

-The statement - -

-     function f () body end
-

-translates to - -

-     f = function () body end
-

-The statement - -

-     function t.a.b.c.f () body end
-

-translates to - -

-     t.a.b.c.f = function () body end
-

-The statement - -

-     local function f () body end
-

-translates to - -

-     local f; f = function () body end
-

-not to - -

-     local f = function () body end
-

-(This only makes a difference when the body of the function -contains references to f.) - - -

-A function definition is an executable expression, -whose value has type function. -When Lua pre-compiles a chunk, -all its function bodies are pre-compiled too. -Then, whenever Lua executes the function definition, -the function is instantiated (or closed). -This function instance (or closure) -is the final value of the expression. -Different instances of the same function -can refer to different external local variables -and can have different environment tables. - - -

-Parameters act as local variables that are -initialized with the argument values: - -

-	parlist ::= namelist [`,´ `...´] | `...´
-

-When a function is called, -the list of arguments is adjusted to -the length of the list of parameters, -unless the function is a variadic or vararg function, -which is -indicated by three dots ('...') at the end of its parameter list. -A vararg function does not adjust its argument list; -instead, it collects all extra arguments and supplies them -to the function through a vararg expression, -which is also written as three dots. -The value of this expression is a list of all actual extra arguments, -similar to a function with multiple results. -If a vararg expression is used inside another expression -or in the middle of a list of expressions, -then its return list is adjusted to one element. -If the expression is used as the last element of a list of expressions, -then no adjustment is made -(unless that last expression is enclosed in parentheses). - - -

-As an example, consider the following definitions: - -

-     function f(a, b) end
-     function g(a, b, ...) end
-     function r() return 1,2,3 end
-

-Then, we have the following mapping from arguments to parameters and -to the vararg expression: - -

-     CALL            PARAMETERS
-     
-     f(3)             a=3, b=nil
-     f(3, 4)          a=3, b=4
-     f(3, 4, 5)       a=3, b=4
-     f(r(), 10)       a=1, b=10
-     f(r())           a=1, b=2
-     
-     g(3)             a=3, b=nil, ... -->  (nothing)
-     g(3, 4)          a=3, b=4,   ... -->  (nothing)
-     g(3, 4, 5, 8)    a=3, b=4,   ... -->  5  8
-     g(5, r())        a=5, b=1,   ... -->  2  3
-
- -

-Results are returned using the return statement (see §2.4.4). -If control reaches the end of a function -without encountering a return statement, -then the function returns with no results. - - -

-The colon syntax -is used for defining methods, -that is, functions that have an implicit extra parameter self. -Thus, the statement - -

-     function t.a.b.c:f (params) body end
-

-is syntactic sugar for - -

-     t.a.b.c.f = function (self, params) body end
-
- - - - - - -

2.6 - Visibility Rules

- -

- -Lua is a lexically scoped language. -The scope of variables begins at the first statement after -their declaration and lasts until the end of the innermost block that -includes the declaration. -Consider the following example: - -

-     x = 10                -- global variable
-     do                    -- new block
-       local x = x         -- new 'x', with value 10
-       print(x)            --> 10
-       x = x+1
-       do                  -- another block
-         local x = x+1     -- another 'x'
-         print(x)          --> 12
-       end
-       print(x)            --> 11
-     end
-     print(x)              --> 10  (the global one)
-
- -

-Notice that, in a declaration like local x = x, -the new x being declared is not in scope yet, -and so the second x refers to the outside variable. - - -

-Because of the lexical scoping rules, -local variables can be freely accessed by functions -defined inside their scope. -A local variable used by an inner function is called -an upvalue, or external local variable, -inside the inner function. - - -

-Notice that each execution of a local statement -defines new local variables. -Consider the following example: - -

-     a = {}
-     local x = 20
-     for i=1,10 do
-       local y = 0
-       a[i] = function () y=y+1; return x+y end
-     end
-

-The loop creates ten closures -(that is, ten instances of the anonymous function). -Each of these closures uses a different y variable, -while all of them share the same x. - - - - - -

2.7 - Error Handling

- -

-Because Lua is an embedded extension language, -all Lua actions start from C code in the host program -calling a function from the Lua library (see lua_pcall). -Whenever an error occurs during Lua compilation or execution, -control returns to C, -which can take appropriate measures -(such as printing an error message). - - -

-Lua code can explicitly generate an error by calling the -error function. -If you need to catch errors in Lua, -you can use the pcall function. - - - - - -

2.8 - Metatables

- -

-Every value in Lua can have a metatable. -This metatable is an ordinary Lua table -that defines the behavior of the original value -under certain special operations. -You can change several aspects of the behavior -of operations over a value by setting specific fields in its metatable. -For instance, when a non-numeric value is the operand of an addition, -Lua checks for a function in the field "__add" in its metatable. -If it finds one, -Lua calls this function to perform the addition. - - -

-We call the keys in a metatable events -and the values metamethods. -In the previous example, the event is "add" -and the metamethod is the function that performs the addition. - - -

-You can query the metatable of any value -through the getmetatable function. - - -

-You can replace the metatable of tables -through the setmetatable -function. -You cannot change the metatable of other types from Lua -(except by using the debug library); -you must use the C API for that. - - -

-Tables and full userdata have individual metatables -(although multiple tables and userdata can share their metatables). -Values of all other types share one single metatable per type; -that is, there is one single metatable for all numbers, -one for all strings, etc. - - -

-A metatable controls how an object behaves in arithmetic operations, -order comparisons, concatenation, length operation, and indexing. -A metatable also can define a function to be called when a userdata -is garbage collected. -For each of these operations Lua associates a specific key -called an event. -When Lua performs one of these operations over a value, -it checks whether this value has a metatable with the corresponding event. -If so, the value associated with that key (the metamethod) -controls how Lua will perform the operation. - - -

-Metatables control the operations listed next. -Each operation is identified by its corresponding name. -The key for each operation is a string with its name prefixed by -two underscores, '__'; -for instance, the key for operation "add" is the -string "__add". -The semantics of these operations is better explained by a Lua function -describing how the interpreter executes the operation. - - -

-The code shown here in Lua is only illustrative; -the real behavior is hard coded in the interpreter -and it is much more efficient than this simulation. -All functions used in these descriptions -(rawget, tonumber, etc.) -are described in §5.1. -In particular, to retrieve the metamethod of a given object, -we use the expression - -

-     metatable(obj)[event]
-

-This should be read as - -

-     rawget(getmetatable(obj) or {}, event)
-

- -That is, the access to a metamethod does not invoke other metamethods, -and the access to objects with no metatables does not fail -(it simply results in nil). - - - -

    - -
  • "add": -the + operation. - - - -

    -The function getbinhandler below defines how Lua chooses a handler -for a binary operation. -First, Lua tries the first operand. -If its type does not define a handler for the operation, -then Lua tries the second operand. - -

    -     function getbinhandler (op1, op2, event)
-       return metatable(op1)[event] or metatable(op2)[event]
-     end
-

    -By using this function, -the behavior of the op1 + op2 is - -

    -     function add_event (op1, op2)
-       local o1, o2 = tonumber(op1), tonumber(op2)
-       if o1 and o2 then  -- both operands are numeric?
-         return o1 + o2   -- '+' here is the primitive 'add'

2.9 - Environments

- -

-Besides metatables, -objects of types thread, function, and userdata -have another table associated with them, -called their environment. -Like metatables, environments are regular tables and -multiple objects can share the same environment. - - -

-Threads are created sharing the environment of the creating thread. -Userdata and C functions are created sharing the environment -of the creating C function. -Non-nested Lua functions -(created by loadfile, loadstring or load) -are created sharing the environment of the creating thread. -Nested Lua functions are created sharing the environment of -the creating Lua function. - - -

-Environments associated with userdata have no meaning for Lua. -It is only a convenience feature for programmers to associate a table to -a userdata. - - -

-Environments associated with threads are called -global environments. -They are used as the default environment for threads and -non-nested Lua functions created by the thread -and can be directly accessed by C code (see §3.3). - - -

-The environment associated with a C function can be directly -accessed by C code (see §3.3). -It is used as the default environment for other C functions -and userdata created by the function. - - -

-Environments associated with Lua functions are used to resolve -all accesses to global variables within the function (see §2.3). -They are used as the default environment for nested Lua functions -created by the function. - - -

-You can change the environment of a Lua function or the -running thread by calling setfenv. -You can get the environment of a Lua function or the running thread -by calling getfenv. -To manipulate the environment of other objects -(userdata, C functions, other threads) you must -use the C API. - - - - - -

2.10 - Garbage Collection

- -

-Lua performs automatic memory management. -This means that -you have to worry neither about allocating memory for new objects -nor about freeing it when the objects are no longer needed. -Lua manages memory automatically by running -a garbage collector from time to time -to collect all dead objects -(that is, objects that are no longer accessible from Lua). -All memory used by Lua is subject to automatic management: -tables, userdata, functions, threads, strings, etc. - - -

-Lua implements an incremental mark-and-sweep collector. -It uses two numbers to control its garbage-collection cycles: -the garbage-collector pause and -the garbage-collector step multiplier. -Both use percentage points as units -(so that a value of 100 means an internal value of 1). - - -

-The garbage-collector pause -controls how long the collector waits before starting a new cycle. -Larger values make the collector less aggressive. -Values smaller than 100 mean the collector will not wait to -start a new cycle. -A value of 200 means that the collector waits for the total memory in use -to double before starting a new cycle. - - -

-The step multiplier -controls the relative speed of the collector relative to -memory allocation. -Larger values make the collector more aggressive but also increase -the size of each incremental step. -Values smaller than 100 make the collector too slow and -can result in the collector never finishing a cycle. -The default, 200, means that the collector runs at "twice" -the speed of memory allocation. - - -

-You can change these numbers by calling lua_gc in C -or collectgarbage in Lua. -With these functions you can also control -the collector directly (e.g., stop and restart it). - - - -

2.10.1 - Garbage-Collection Metamethods

- -

-Using the C API, -you can set garbage-collector metamethods for userdata (see §2.8). -These metamethods are also called finalizers. -Finalizers allow you to coordinate Lua's garbage collection -with external resource management -(such as closing files, network or database connections, -or freeing your own memory). - - -

-Garbage userdata with a field __gc in their metatables are not -collected immediately by the garbage collector. -Instead, Lua puts them in a list. -After the collection, -Lua does the equivalent of the following function -for each userdata in that list: - -

-     function gc_event (udata)
-       local h = metatable(udata).__gc
-       if h then
-         h(udata)
-       end
-     end
-
- -

-At the end of each garbage-collection cycle, -the finalizers for userdata are called in reverse -order of their creation, -among those collected in that cycle. -That is, the first finalizer to be called is the one associated -with the userdata created last in the program. -The userdata itself is freed only in the next garbage-collection cycle. - - - - - -

2.10.2 - Weak Tables

- -

-A weak table is a table whose elements are -weak references. -A weak reference is ignored by the garbage collector. -In other words, -if the only references to an object are weak references, -then the garbage collector will collect this object. - - -

-A weak table can have weak keys, weak values, or both. -A table with weak keys allows the collection of its keys, -but prevents the collection of its values. -A table with both weak keys and weak values allows the collection of -both keys and values. -In any case, if either the key or the value is collected, -the whole pair is removed from the table. -The weakness of a table is controlled by the -__mode field of its metatable. -If the __mode field is a string containing the character 'k', -the keys in the table are weak. -If __mode contains 'v', -the values in the table are weak. - - -

-After you use a table as a metatable, -you should not change the value of its __mode field. -Otherwise, the weak behavior of the tables controlled by this -metatable is undefined. - - - - - - - -

2.11 - Coroutines

- -

-Lua supports coroutines, -also called collaborative multithreading. -A coroutine in Lua represents an independent thread of execution. -Unlike threads in multithread systems, however, -a coroutine only suspends its execution by explicitly calling -a yield function. - - -

-You create a coroutine with a call to coroutine.create. -Its sole argument is a function -that is the main function of the coroutine. -The create function only creates a new coroutine and -returns a handle to it (an object of type thread); -it does not start the coroutine execution. - - -

-When you first call coroutine.resume, -passing as its first argument -a thread returned by coroutine.create, -the coroutine starts its execution, -at the first line of its main function. -Extra arguments passed to coroutine.resume are passed on -to the coroutine main function. -After the coroutine starts running, -it runs until it terminates or yields. - - -

-A coroutine can terminate its execution in two ways: -normally, when its main function returns -(explicitly or implicitly, after the last instruction); -and abnormally, if there is an unprotected error. -In the first case, coroutine.resume returns true, -plus any values returned by the coroutine main function. -In case of errors, coroutine.resume returns false -plus an error message. - - -

-A coroutine yields by calling coroutine.yield. -When a coroutine yields, -the corresponding coroutine.resume returns immediately, -even if the yield happens inside nested function calls -(that is, not in the main function, -but in a function directly or indirectly called by the main function). -In the case of a yield, coroutine.resume also returns true, -plus any values passed to coroutine.yield. -The next time you resume the same coroutine, -it continues its execution from the point where it yielded, -with the call to coroutine.yield returning any extra -arguments passed to coroutine.resume. - - -

-Like coroutine.create, -the coroutine.wrap function also creates a coroutine, -but instead of returning the coroutine itself, -it returns a function that, when called, resumes the coroutine. -Any arguments passed to this function -go as extra arguments to coroutine.resume. -coroutine.wrap returns all the values returned by coroutine.resume, -except the first one (the boolean error code). -Unlike coroutine.resume, -coroutine.wrap does not catch errors; -any error is propagated to the caller. - - -

-As an example, -consider the following code: - -

-     function foo (a)
-       print("foo", a)
-       return coroutine.yield(2*a)
-     end
-     
-     co = coroutine.create(function (a,b)
-           print("co-body", a, b)
-           local r = foo(a+1)
-           print("co-body", r)
-           local r, s = coroutine.yield(a+b, a-b)
-           print("co-body", r, s)
-           return b, "end"
-     end)
-            
-     print("main", coroutine.resume(co, 1, 10))
-     print("main", coroutine.resume(co, "r"))
-     print("main", coroutine.resume(co, "x", "y"))
-     print("main", coroutine.resume(co, "x", "y"))
-

-When you run it, it produces the following output: - -

-     co-body 1       10
-     foo     2
-     
-     main    true    4
-     co-body r
-     main    true    11      -9
-     co-body x       y
-     main    true    10      end
-     main    false   cannot resume dead coroutine
-

3 - The Application Program Interface

- -

- -This section describes the C API for Lua, that is, -the set of C functions available to the host program to communicate -with Lua. -All API functions and related types and constants -are declared in the header file lua.h. - - -

-Even when we use the term "function", -any facility in the API may be provided as a macro instead. -All such macros use each of their arguments exactly once -(except for the first argument, which is always a Lua state), -and so do not generate any hidden side-effects. - - -

-As in most C libraries, -the Lua API functions do not check their arguments for validity or consistency. -However, you can change this behavior by compiling Lua -with a proper definition for the macro luai_apicheck, -in file luaconf.h. - - - -

3.1 - The Stack

- -

-Lua uses a virtual stack to pass values to and from C. -Each element in this stack represents a Lua value -(nil, number, string, etc.). - - -

-Whenever Lua calls C, the called function gets a new stack, -which is independent of previous stacks and of stacks of -C functions that are still active. -This stack initially contains any arguments to the C function -and it is where the C function pushes its results -to be returned to the caller (see lua_CFunction). - - -

-For convenience, -most query operations in the API do not follow a strict stack discipline. -Instead, they can refer to any element in the stack -by using an index: -A positive index represents an absolute stack position -(starting at 1); -a negative index represents an offset relative to the top of the stack. -More specifically, if the stack has n elements, -then index 1 represents the first element -(that is, the element that was pushed onto the stack first) -and -index n represents the last element; -index -1 also represents the last element -(that is, the element at the top) -and index -n represents the first element. -We say that an index is valid -if it lies between 1 and the stack top -(that is, if 1 ≤ abs(index) ≤ top). - - - - - - -

3.2 - Stack Size

- -

-When you interact with Lua API, -you are responsible for ensuring consistency. -In particular, -you are responsible for controlling stack overflow. -You can use the function lua_checkstack -to grow the stack size. - - -

-Whenever Lua calls C, -it ensures that at least LUA_MINSTACK stack positions are available. -LUA_MINSTACK is defined as 20, -so that usually you do not have to worry about stack space -unless your code has loops pushing elements onto the stack. - - -

-Most query functions accept as indices any value inside the -available stack space, that is, indices up to the maximum stack size -you have set through lua_checkstack. -Such indices are called acceptable indices. -More formally, we define an acceptable index -as follows: - -

-     (index < 0 && abs(index) <= top) ||
-     (index > 0 && index <= stackspace)
-

-Note that 0 is never an acceptable index. - - - - - -

3.3 - Pseudo-Indices

- -

-Unless otherwise noted, -any function that accepts valid indices can also be called with -pseudo-indices, -which represent some Lua values that are accessible to C code -but which are not in the stack. -Pseudo-indices are used to access the thread environment, -the function environment, -the registry, -and the upvalues of a C function (see §3.4). - - -

-The thread environment (where global variables live) is -always at pseudo-index LUA_GLOBALSINDEX. -The environment of the running C function is always -at pseudo-index LUA_ENVIRONINDEX. - - -

-To access and change the value of global variables, -you can use regular table operations over an environment table. -For instance, to access the value of a global variable, do - -

-     lua_getfield(L, LUA_GLOBALSINDEX, varname);
-
- - - - -

3.4 - C Closures

- -

-When a C function is created, -it is possible to associate some values with it, -thus creating a C closure; -these values are called upvalues and are -accessible to the function whenever it is called -(see lua_pushcclosure). - - -

-Whenever a C function is called, -its upvalues are located at specific pseudo-indices. -These pseudo-indices are produced by the macro -lua_upvalueindex. -The first value associated with a function is at position -lua_upvalueindex(1), and so on. -Any access to lua_upvalueindex(n), -where n is greater than the number of upvalues of the -current function (but not greater than 256), -produces an acceptable (but invalid) index. - - - - - -

3.5 - Registry

- -

-Lua provides a registry, -a pre-defined table that can be used by any C code to -store whatever Lua value it needs to store. -This table is always located at pseudo-index -LUA_REGISTRYINDEX. -Any C library can store data into this table, -but it should take care to choose keys different from those used -by other libraries, to avoid collisions. -Typically, you should use as key a string containing your library name -or a light userdata with the address of a C object in your code. - - -

-The integer keys in the registry are used by the reference mechanism, -implemented by the auxiliary library, -and therefore should not be used for other purposes. - - - - - -

3.6 - Error Handling in C

- -

-Internally, Lua uses the C longjmp facility to handle errors. -(You can also choose to use exceptions if you use C++; -see file luaconf.h.) -When Lua faces any error -(such as memory allocation errors, type errors, syntax errors, -and runtime errors) -it raises an error; -that is, it does a long jump. -A protected environment uses setjmp -to set a recover point; -any error jumps to the most recent active recover point. - - -

-Most functions in the API can throw an error, -for instance due to a memory allocation error. -The documentation for each function indicates whether -it can throw errors. - - -

-Inside a C function you can throw an error by calling lua_error. - - - - - -

3.7 - Functions and Types

- -

-Here we list all functions and types from the C API in -alphabetical order. -Each function has an indicator like this: -[-o, +p, x] - - -

-The first field, o, -is how many elements the function pops from the stack. -The second field, p, -is how many elements the function pushes onto the stack. -(Any function always pushes its results after popping its arguments.) -A field in the form x|y means the function can push (or pop) -x or y elements, -depending on the situation; -an interrogation mark '?' means that -we cannot know how many elements the function pops/pushes -by looking only at its arguments -(e.g., they may depend on what is on the stack). -The third field, x, -tells whether the function may throw errors: -'-' means the function never throws any error; -'m' means the function may throw an error -only due to not enough memory; -'e' means the function may throw other kinds of errors; -'v' means the function may throw an error on purpose. - - - -

lua_Alloc

-
typedef void * (*lua_Alloc) (void *ud,
-                             void *ptr,
-                             size_t osize,
-                             size_t nsize);
- -

-The type of the memory-allocation function used by Lua states. -The allocator function must provide a -functionality similar to realloc, -but not exactly the same. -Its arguments are -ud, an opaque pointer passed to lua_newstate; -ptr, a pointer to the block being allocated/reallocated/freed; -osize, the original size of the block; -nsize, the new size of the block. -ptr is NULL if and only if osize is zero. -When nsize is zero, the allocator must return NULL; -if osize is not zero, -it should free the block pointed to by ptr. -When nsize is not zero, the allocator returns NULL -if and only if it cannot fill the request. -When nsize is not zero and osize is zero, -the allocator should behave like malloc. -When nsize and osize are not zero, -the allocator behaves like realloc. -Lua assumes that the allocator never fails when -osize >= nsize. - - -

-Here is a simple implementation for the allocator function. -It is used in the auxiliary library by luaL_newstate. - -

-     static void *l_alloc (void *ud, void *ptr, size_t osize,
-                                                size_t nsize) {
-       (void)ud;  (void)osize;  /* not used */
-       if (nsize == 0) {
-         free(ptr);
-         return NULL;
-       }
-       else
-         return realloc(ptr, nsize);
-     }
-

-This code assumes -that free(NULL) has no effect and that -realloc(NULL, size) is equivalent to malloc(size). -ANSI C ensures both behaviors. - - - - - -

lua_atpanic

-[-0, +0, -] -

lua_CFunction lua_atpanic (lua_State *L, lua_CFunction panicf);
- -

-Sets a new panic function and returns the old one. - - -

-If an error happens outside any protected environment, -Lua calls a panic function -and then calls exit(EXIT_FAILURE), -thus exiting the host application. -Your panic function can avoid this exit by -never returning (e.g., doing a long jump). - - -

-The panic function can access the error message at the top of the stack. - - - - - -

lua_call

-[-(nargs + 1), +nresults, e] -

void lua_call (lua_State *L, int nargs, int nresults);
- -

-Calls a function. - - -

-To call a function you must use the following protocol: -first, the function to be called is pushed onto the stack; -then, the arguments to the function are pushed -in direct order; -that is, the first argument is pushed first. -Finally you call lua_call; -nargs is the number of arguments that you pushed onto the stack. -All arguments and the function value are popped from the stack -when the function is called. -The function results are pushed onto the stack when the function returns. -The number of results is adjusted to nresults, -unless nresults is LUA_MULTRET. -In this case, all results from the function are pushed. -Lua takes care that the returned values fit into the stack space. -The function results are pushed onto the stack in direct order -(the first result is pushed first), -so that after the call the last result is on the top of the stack. - - -

-Any error inside the called function is propagated upwards -(with a longjmp). - - -

-The following example shows how the host program can do the -equivalent to this Lua code: - -

-     a = f("how", t.x, 14)
-

-Here it is in C: - -

-     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
-     lua_pushstring(L, "how");                        /* 1st argument */
-     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
-     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
-     lua_remove(L, -2);                  /* remove 't' from the stack */
-     lua_pushinteger(L, 14);                          /* 3rd argument */
-     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
-     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */
-

-Note that the code above is "balanced": -at its end, the stack is back to its original configuration. -This is considered good programming practice. - - - - - -

lua_CFunction

-
typedef int (*lua_CFunction) (lua_State *L);
- -

-Type for C functions. - - -

-In order to communicate properly with Lua, -a C function must use the following protocol, -which defines the way parameters and results are passed: -a C function receives its arguments from Lua in its stack -in direct order (the first argument is pushed first). -So, when the function starts, -lua_gettop(L) returns the number of arguments received by the function. -The first argument (if any) is at index 1 -and its last argument is at index lua_gettop(L). -To return values to Lua, a C function just pushes them onto the stack, -in direct order (the first result is pushed first), -and returns the number of results. -Any other value in the stack below the results will be properly -discarded by Lua. -Like a Lua function, a C function called by Lua can also return -many results. - - -

-As an example, the following function receives a variable number -of numerical arguments and returns their average and sum: - -

-     static int foo (lua_State *L) {
-       int n = lua_gettop(L);    /* number of arguments */
-       lua_Number sum = 0;
-       int i;
-       for (i = 1; i <= n; i++) {
-         if (!lua_isnumber(L, i)) {
-           lua_pushstring(L, "incorrect argument");
-           lua_error(L);
-         }
-         sum += lua_tonumber(L, i);
-       }
-       lua_pushnumber(L, sum/n);        /* first result */
-       lua_pushnumber(L, sum);         /* second result */
-       return 2;                   /* number of results */
-     }
-
- - - - -

lua_checkstack

-[-0, +0, m] -

int lua_checkstack (lua_State *L, int extra);
- -

-Ensures that there are at least extra free stack slots in the stack. -It returns false if it cannot grow the stack to that size. -This function never shrinks the stack; -if the stack is already larger than the new size, -it is left unchanged. - - - - - -

lua_close

-[-0, +0, -] -

void lua_close (lua_State *L);
- -

-Destroys all objects in the given Lua state -(calling the corresponding garbage-collection metamethods, if any) -and frees all dynamic memory used by this state. -On several platforms, you may not need to call this function, -because all resources are naturally released when the host program ends. -On the other hand, long-running programs, -such as a daemon or a web server, -might need to release states as soon as they are not needed, -to avoid growing too large. - - - - - -

lua_concat

-[-n, +1, e] -

void lua_concat (lua_State *L, int n);
- -

-Concatenates the n values at the top of the stack, -pops them, and leaves the result at the top. -If n is 1, the result is the single value on the stack -(that is, the function does nothing); -if n is 0, the result is the empty string. -Concatenation is performed following the usual semantics of Lua -(see §2.5.4). - - - - - -

lua_cpcall

-[-0, +(0|1), -] -

int lua_cpcall (lua_State *L, lua_CFunction func, void *ud);
- -

-Calls the C function func in protected mode. -func starts with only one element in its stack, -a light userdata containing ud. -In case of errors, -lua_cpcall returns the same error codes as lua_pcall, -plus the error object on the top of the stack; -otherwise, it returns zero, and does not change the stack. -All values returned by func are discarded. - - - - - -

lua_createtable

-[-0, +1, m] -

void lua_createtable (lua_State *L, int narr, int nrec);
- -

-Creates a new empty table and pushes it onto the stack. -The new table has space pre-allocated -for narr array elements and nrec non-array elements. -This pre-allocation is useful when you know exactly how many elements -the table will have. -Otherwise you can use the function lua_newtable. - - - - - -

lua_dump

-[-0, +0, m] -

int lua_dump (lua_State *L, lua_Writer writer, void *data);
- -

-Dumps a function as a binary chunk. -Receives a Lua function on the top of the stack -and produces a binary chunk that, -if loaded again, -results in a function equivalent to the one dumped. -As it produces parts of the chunk, -lua_dump calls function writer (see lua_Writer) -with the given data -to write them. - - -

-The value returned is the error code returned by the last -call to the writer; -0 means no errors. - - -

-This function does not pop the Lua function from the stack. - - - - - -

lua_equal

-[-0, +0, e] -

int lua_equal (lua_State *L, int index1, int index2);
- -

-Returns 1 if the two values in acceptable indices index1 and -index2 are equal, -following the semantics of the Lua == operator -(that is, may call metamethods). -Otherwise returns 0. -Also returns 0 if any of the indices is non valid. - - - - - -

lua_error

-[-1, +0, v] -

int lua_error (lua_State *L);
- -

-Generates a Lua error. -The error message (which can actually be a Lua value of any type) -must be on the stack top. -This function does a long jump, -and therefore never returns. -(see luaL_error). - - - - - -

lua_gc

-[-0, +0, e] -

int lua_gc (lua_State *L, int what, int data);
- -

-Controls the garbage collector. - - -

-This function performs several tasks, -according to the value of the parameter what: - -

    - -
  • LUA_GCSTOP: -stops the garbage collector. -
    • - -
  • LUA_GCRESTART: -restarts the garbage collector. -
    • - -
  • LUA_GCCOLLECT: -performs a full garbage-collection cycle. -
    • - -
  • LUA_GCCOUNT: -returns the current amount of memory (in Kbytes) in use by Lua. -
    • - -
  • LUA_GCCOUNTB: -returns the remainder of dividing the current amount of bytes of -memory in use by Lua by 1024. -
    • - -
  • LUA_GCSTEP: -performs an incremental step of garbage collection. -The step "size" is controlled by data -(larger values mean more steps) in a non-specified way. -If you want to control the step size -you must experimentally tune the value of data. -The function returns 1 if the step finished a -garbage-collection cycle. -
    • - -
  • LUA_GCSETPAUSE: -sets data as the new value -for the pause of the collector (see §2.10). -The function returns the previous value of the pause. -
    • - -
  • LUA_GCSETSTEPMUL: -sets data as the new value for the step multiplier of -the collector (see §2.10). -The function returns the previous value of the step multiplier. -
    • - -
- - - - -

lua_getallocf

-[-0, +0, -] -

lua_Alloc lua_getallocf (lua_State *L, void **ud);
- -

-Returns the memory-allocation function of a given state. -If ud is not NULL, Lua stores in *ud the -opaque pointer passed to lua_newstate. - - - - - -

lua_getfenv

-[-0, +1, -] -

void lua_getfenv (lua_State *L, int index);
- -

-Pushes onto the stack the environment table of -the value at the given index. - - - - - -

lua_getfield

-[-0, +1, e] -

void lua_getfield (lua_State *L, int index, const char *k);
- -

-Pushes onto the stack the value t[k], -where t is the value at the given valid index. -As in Lua, this function may trigger a metamethod -for the "index" event (see §2.8). - - - - - -

lua_getglobal

-[-0, +1, e] -

void lua_getglobal (lua_State *L, const char *name);
- -

-Pushes onto the stack the value of the global name. -It is defined as a macro: - -

-     #define lua_getglobal(L,s)  lua_getfield(L, LUA_GLOBALSINDEX, s)
-
- - - - -

lua_getmetatable

-[-0, +(0|1), -] -

int lua_getmetatable (lua_State *L, int index);
- -

-Pushes onto the stack the metatable of the value at the given -acceptable index. -If the index is not valid, -or if the value does not have a metatable, -the function returns 0 and pushes nothing on the stack. - - - - - -

lua_gettable

-[-1, +1, e] -

void lua_gettable (lua_State *L, int index);
- -

-Pushes onto the stack the value t[k], -where t is the value at the given valid index -and k is the value at the top of the stack. - - -

-This function pops the key from the stack -(putting the resulting value in its place). -As in Lua, this function may trigger a metamethod -for the "index" event (see §2.8). - - - - - -

lua_gettop

-[-0, +0, -] -

int lua_gettop (lua_State *L);
- -

-Returns the index of the top element in the stack. -Because indices start at 1, -this result is equal to the number of elements in the stack -(and so 0 means an empty stack). - - - - - -

lua_insert

-[-1, +1, -] -

void lua_insert (lua_State *L, int index);
- -

-Moves the top element into the given valid index, -shifting up the elements above this index to open space. -Cannot be called with a pseudo-index, -because a pseudo-index is not an actual stack position. - - - - - -

lua_Integer

-
typedef ptrdiff_t lua_Integer;
- -

-The type used by the Lua API to represent integral values. - - -

-By default it is a ptrdiff_t, -which is usually the largest signed integral type the machine handles -"comfortably". - - - - - -

lua_isboolean

-[-0, +0, -] -

int lua_isboolean (lua_State *L, int index);
- -

-Returns 1 if the value at the given acceptable index has type boolean, -and 0 otherwise. - - - - - -

- -

-Returns 1 if the value at the given acceptable index is nil, -and 0 otherwise. - - - - - -

lua_isnone

-[-0, +0, -] -

int lua_isnone (lua_State *L, int index);
- -

-Returns 1 if the given acceptable index is not valid -(that is, it refers to an element outside the current stack), -and 0 otherwise. - - - - - -

lua_isnoneornil

-[-0, +0, -] -

int lua_isnoneornil (lua_State *L, int index);
- -

-Returns 1 if the given acceptable index is not valid -(that is, it refers to an element outside the current stack) -or if the value at this index is nil, -and 0 otherwise. - - - - - -

lua_isnumber

-[-0, +0, -] -

int lua_isnumber (lua_State *L, int index);
- -

-Returns 1 if the value at the given acceptable index is a number -or a string convertible to a number, -and 0 otherwise. - - - - - -

lua_isstring

-[-0, +0, -] -

int lua_isstring (lua_State *L, int index);
- -

-Returns 1 if the value at the given acceptable index is a string -or a number (which is always convertible to a string), -and 0 otherwise. - - - - - -

lua_istable

-[-0, +0, -] -

int lua_istable (lua_State *L, int index);
- -

-Returns 1 if the value at the given acceptable index is a table, -and 0 otherwise. - - - - - -

lua_isthread

-[-0, +0, -] -

int lua_isthread (lua_State *L, int index);
- -

-Returns 1 if the value at the given acceptable index is a thread, -and 0 otherwise. - - - - - -

lua_isuserdata

-[-0, +0, -] -

int lua_isuserdata (lua_State *L, int index);
- -

-Returns 1 if the value at the given acceptable index is a userdata -(either full or light), and 0 otherwise. - - - - - -

lua_lessthan

-[-0, +0, e] -

int lua_lessthan (lua_State *L, int index1, int index2);
- -

-Returns 1 if the value at acceptable index index1 is smaller -than the value at acceptable index index2, -following the semantics of the Lua < operator -(that is, may call metamethods). -Otherwise returns 0. -Also returns 0 if any of the indices is non valid. - - - - - -

lua_load

-[-0, +1, -] -

int lua_load (lua_State *L,
-              lua_Reader reader,
-              void *data,
-              const char *chunkname);
- -

-Loads a Lua chunk. -If there are no errors, -lua_load pushes the compiled chunk as a Lua -function on top of the stack. -Otherwise, it pushes an error message. -The return values of lua_load are: - -

    - -
  • 0: no errors;
    • - -
  • LUA_ERRSYNTAX: -syntax error during pre-compilation;
    • - -
  • LUA_ERRMEM: -memory allocation error.
    • - -
- -

-This function only loads a chunk; -it does not run it. - - -

-lua_load automatically detects whether the chunk is text or binary, -and loads it accordingly (see program luac). - - -

-The lua_load function uses a user-supplied reader function -to read the chunk (see lua_Reader). -The data argument is an opaque value passed to the reader function. - - -

-The chunkname argument gives a name to the chunk, -which is used for error messages and in debug information (see §3.8). - - - - - -

lua_newstate

-[-0, +0, -] -

lua_State *lua_newstate (lua_Alloc f, void *ud);
- -

-Creates a new, independent state. -Returns NULL if cannot create the state -(due to lack of memory). -The argument f is the allocator function; -Lua does all memory allocation for this state through this function. -The second argument, ud, is an opaque pointer that Lua -simply passes to the allocator in every call. - - - - - -

lua_newtable

-[-0, +1, m] -

void lua_newtable (lua_State *L);
- -

-Creates a new empty table and pushes it onto the stack. -It is equivalent to lua_createtable(L, 0, 0). - - - - - -

lua_newthread

-[-0, +1, m] -

lua_State *lua_newthread (lua_State *L);
- -

-Creates a new thread, pushes it on the stack, -and returns a pointer to a lua_State that represents this new thread. -The new state returned by this function shares with the original state -all global objects (such as tables), -but has an independent execution stack. - - -

-There is no explicit function to close or to destroy a thread. -Threads are subject to garbage collection, -like any Lua object. - - - - - -

lua_newuserdata

-[-0, +1, m] -

void *lua_newuserdata (lua_State *L, size_t size);
- -

-This function allocates a new block of memory with the given size, -pushes onto the stack a new full userdata with the block address, -and returns this address. - - -

-Userdata represent C values in Lua. -A full userdata represents a block of memory. -It is an object (like a table): -you must create it, it can have its own metatable, -and you can detect when it is being collected. -A full userdata is only equal to itself (under raw equality). - - -

-When Lua collects a full userdata with a gc metamethod, -Lua calls the metamethod and marks the userdata as finalized. -When this userdata is collected again then -Lua frees its corresponding memory. - - - - - -

lua_next

-[-1, +(2|0), e] -

int lua_next (lua_State *L, int index);
- -

-Pops a key from the stack, -and pushes a key-value pair from the table at the given index -(the "next" pair after the given key). -If there are no more elements in the table, -then lua_next returns 0 (and pushes nothing). - - -

-A typical traversal looks like this: - -

-     /* table is in the stack at index 't' */
-     lua_pushnil(L);  /* first key */
-     while (lua_next(L, t) != 0) {
-       /* uses 'key' (at index -2) and 'value' (at index -1) */
-       printf("%s - %s\n",
-              lua_typename(L, lua_type(L, -2)),
-              lua_typename(L, lua_type(L, -1)));
-       /* removes 'value'; keeps 'key' for next iteration */
-       lua_pop(L, 1);
-     }
-
- -

-While traversing a table, -do not call lua_tolstring directly on a key, -unless you know that the key is actually a string. -Recall that lua_tolstring changes -the value at the given index; -this confuses the next call to lua_next. - - - - - -

lua_Number

-
typedef double lua_Number;
- -

-The type of numbers in Lua. -By default, it is double, but that can be changed in luaconf.h. - - -

-Through the configuration file you can change -Lua to operate with another type for numbers (e.g., float or long). - - - - - -

lua_objlen

-[-0, +0, -] -

size_t lua_objlen (lua_State *L, int index);
- -

-Returns the "length" of the value at the given acceptable index: -for strings, this is the string length; -for tables, this is the result of the length operator ('#'); -for userdata, this is the size of the block of memory allocated -for the userdata; -for other values, it is 0. - - - - - -

lua_pcall

-[-(nargs + 1), +(nresults|1), -] -

int lua_pcall (lua_State *L, int nargs, int nresults, int errfunc);
- -

-Calls a function in protected mode. - - -

-Both nargs and nresults have the same meaning as -in lua_call. -If there are no errors during the call, -lua_pcall behaves exactly like lua_call. -However, if there is any error, -lua_pcall catches it, -pushes a single value on the stack (the error message), -and returns an error code. -Like lua_call, -lua_pcall always removes the function -and its arguments from the stack. - - -

-If errfunc is 0, -then the error message returned on the stack -is exactly the original error message. -Otherwise, errfunc is the stack index of an -error handler function. -(In the current implementation, this index cannot be a pseudo-index.) -In case of runtime errors, -this function will be called with the error message -and its return value will be the message returned on the stack by lua_pcall. - - -

-Typically, the error handler function is used to add more debug -information to the error message, such as a stack traceback. -Such information cannot be gathered after the return of lua_pcall, -since by then the stack has unwound. - - -

-The lua_pcall function returns 0 in case of success -or one of the following error codes -(defined in lua.h): - -

    - -
  • LUA_ERRRUN: -a runtime error. -
    • - -
  • LUA_ERRMEM: -memory allocation error. -For such errors, Lua does not call the error handler function. -
    • - -
  • LUA_ERRERR: -error while running the error handler function. -
    • - -
- - - - -

lua_pop

-[-n, +0, -] -

void lua_pop (lua_State *L, int n);
- -

-Pops n elements from the stack. - - - - - -

lua_pushboolean

-[-0, +1, -] -

void lua_pushboolean (lua_State *L, int b);
- -

-Pushes a boolean value with value b onto the stack. - - - - - -

lua_pushcclosure

-[-n, +1, m] -

void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);
- -

-Pushes a new C closure onto the stack. - - -

-When a C function is created, -it is possible to associate some values with it, -thus creating a C closure (see §3.4); -these values are then accessible to the function whenever it is called. -To associate values with a C function, -first these values should be pushed onto the stack -(when there are multiple values, the first value is pushed first). -Then lua_pushcclosure -is called to create and push the C function onto the stack, -with the argument n telling how many values should be -associated with the function. -lua_pushcclosure also pops these values from the stack. - - -

-The maximum value for n is 255. - - - - - -

lua_pushcfunction

-[-0, +1, m] -

void lua_pushcfunction (lua_State *L, lua_CFunction f);
- -

-Pushes a C function onto the stack. -This function receives a pointer to a C function -and pushes onto the stack a Lua value of type function that, -when called, invokes the corresponding C function. - - -

-Any function to be registered in Lua must -follow the correct protocol to receive its parameters -and return its results (see lua_CFunction). - - -

-lua_pushcfunction is defined as a macro: - -

-     #define lua_pushcfunction(L,f)  lua_pushcclosure(L,f,0)
-
- - - - -

lua_pushfstring

-[-0, +1, m] -

const char *lua_pushfstring (lua_State *L, const char *fmt, ...);
- -

-Pushes onto the stack a formatted string -and returns a pointer to this string. -It is similar to the C function sprintf, -but has some important differences: - -

    - -
  • -You do not have to allocate space for the result: -the result is a Lua string and Lua takes care of memory allocation -(and deallocation, through garbage collection). -
    • - -
  • -The conversion specifiers are quite restricted. -There are no flags, widths, or precisions. -The conversion specifiers can only be -'%%' (inserts a '%' in the string), -'%s' (inserts a zero-terminated string, with no size restrictions), -'%f' (inserts a lua_Number), -'%p' (inserts a pointer as a hexadecimal numeral), -'%d' (inserts an int), and -'%c' (inserts an int as a character). -
    • - -
- - - - -

lua_pushinteger

-[-0, +1, -] -

void lua_pushinteger (lua_State *L, lua_Integer n);
- -

-Pushes a number with value n onto the stack. - - - - - -

lua_pushlightuserdata

-[-0, +1, -] -

void lua_pushlightuserdata (lua_State *L, void *p);
- -

-Pushes a light userdata onto the stack. - - -

-Userdata represent C values in Lua. -A light userdata represents a pointer. -It is a value (like a number): -you do not create it, it has no individual metatable, -and it is not collected (as it was never created). -A light userdata is equal to "any" -light userdata with the same C address. - - - - - -

lua_pushliteral

-[-0, +1, m] -

void lua_pushliteral (lua_State *L, const char *s);
- -

-This macro is equivalent to lua_pushlstring, -but can be used only when s is a literal string. -In these cases, it automatically provides the string length. - - - - - -

lua_pushlstring

-[-0, +1, m] -

void lua_pushlstring (lua_State *L, const char *s, size_t len);
- -

-Pushes the string pointed to by s with size len -onto the stack. -Lua makes (or reuses) an internal copy of the given string, -so the memory at s can be freed or reused immediately after -the function returns. -The string can contain embedded zeros. - - - - - -

lua_pushnil

-[-0, +1, -] -

void lua_pushnil (lua_State *L);
- -

-Pushes a nil value onto the stack. - - - - - -

- -

-Pushes a number with value n onto the stack. - - - - - -

lua_pushstring

-[-0, +1, m] -

void lua_pushstring (lua_State *L, const char *s);
- -

-Pushes the zero-terminated string pointed to by s -onto the stack. -Lua makes (or reuses) an internal copy of the given string, -so the memory at s can be freed or reused immediately after -the function returns. -The string cannot contain embedded zeros; -it is assumed to end at the first zero. - - - - - -

lua_pushthread

-[-0, +1, -] -

int lua_pushthread (lua_State *L);
- -

-Pushes the thread represented by L onto the stack. -Returns 1 if this thread is the main thread of its state. - - - - - -

-[-0, +1, -] -

void lua_pushvalue (lua_State *L, int index);
- -

-Pushes a copy of the element at the given valid index -onto the stack. - - - - - -

lua_pushvfstring

-[-0, +1, m] -

const char *lua_pushvfstring (lua_State *L,
-                              const char *fmt,
-                              va_list argp);
- -

-Equivalent to lua_pushfstring, except that it receives a va_list -instead of a variable number of arguments. - - - - - -

lua_rawequal

-[-0, +0, -] -

int lua_rawequal (lua_State *L, int index1, int index2);
- -

-Returns 1 if the two values in acceptable indices index1 and -index2 are primitively equal -(that is, without calling metamethods). -Otherwise returns 0. -Also returns 0 if any of the indices are non valid. - - - - - -

lua_rawget

-[-1, +1, -] -

void lua_rawget (lua_State *L, int index);
- -

-Similar to lua_gettable, but does a raw access -(i.e., without metamethods). - - - - - -

lua_rawgeti

-[-0, +1, -] -

void lua_rawgeti (lua_State *L, int index, int n);
- -

-Pushes onto the stack the value t[n], -where t is the value at the given valid index. -The access is raw; -that is, it does not invoke metamethods. - - - - - -

lua_rawset

-[-2, +0, m] -

void lua_rawset (lua_State *L, int index);
- -

-Similar to lua_settable, but does a raw assignment -(i.e., without metamethods). - - - - - -

lua_rawseti

-[-1, +0, m] -

void lua_rawseti (lua_State *L, int index, int n);
- -

-Does the equivalent of t[n] = v, -where t is the value at the given valid index -and v is the value at the top of the stack. - - -

-This function pops the value from the stack. -The assignment is raw; -that is, it does not invoke metamethods. - - - - - -

lua_Reader

-
typedef const char * (*lua_Reader) (lua_State *L,
-                                    void *data,
-                                    size_t *size);
- -

-The reader function used by lua_load. -Every time it needs another piece of the chunk, -lua_load calls the reader, -passing along its data parameter. -The reader must return a pointer to a block of memory -with a new piece of the chunk -and set size to the block size. -The block must exist until the reader function is called again. -To signal the end of the chunk, -the reader must return NULL or set size to zero. -The reader function may return pieces of any size greater than zero. - - - - - -

lua_register

-[-0, +0, e] -

void lua_register (lua_State *L,
-                   const char *name,
-                   lua_CFunction f);
- -

-Sets the C function f as the new value of global name. -It is defined as a macro: - -

lua_remove

-[-1, +0, -] -

void lua_remove (lua_State *L, int index);
- -

-Removes the element at the given valid index, -shifting down the elements above this index to fill the gap. -Cannot be called with a pseudo-index, -because a pseudo-index is not an actual stack position. - - - - - -

lua_replace

-[-1, +0, -] -

void lua_replace (lua_State *L, int index);
- -

-Moves the top element into the given position (and pops it), -without shifting any element -(therefore replacing the value at the given position). - - - - - -

lua_resume

-[-?, +?, -] -

int lua_resume (lua_State *L, int narg);
- -

-Starts and resumes a coroutine in a given thread. - - -

-To start a coroutine, you first create a new thread -(see lua_newthread); -then you push onto its stack the main function plus any arguments; -then you call lua_resume, -with narg being the number of arguments. -This call returns when the coroutine suspends or finishes its execution. -When it returns, the stack contains all values passed to lua_yield, -or all values returned by the body function. -lua_resume returns -LUA_YIELD if the coroutine yields, -0 if the coroutine finishes its execution -without errors, -or an error code in case of errors (see lua_pcall). -In case of errors, -the stack is not unwound, -so you can use the debug API over it. -The error message is on the top of the stack. -To restart a coroutine, you put on its stack only the values to -be passed as results from yield, -and then call lua_resume. - - - - - -

lua_setallocf

-[-0, +0, -] -

void lua_setallocf (lua_State *L, lua_Alloc f, void *ud);
- -

-Changes the allocator function of a given state to f -with user data ud. - - - - - -

lua_setfenv

-[-1, +0, -] -

int lua_setfenv (lua_State *L, int index);
- -

-Pops a table from the stack and sets it as -the new environment for the value at the given index. -If the value at the given index is -neither a function nor a thread nor a userdata, -lua_setfenv returns 0. -Otherwise it returns 1. - - - - - -

lua_setfield

-[-1, +0, e] -

void lua_setfield (lua_State *L, int index, const char *k);
- -

-Does the equivalent to t[k] = v, -where t is the value at the given valid index -and v is the value at the top of the stack. - - -

void lua_setglobal (lua_State *L, const char *name);
- -

-Pops a value from the stack and -sets it as the new value of global name. -It is defined as a macro: - -

int lua_setmetatable (lua_State *L, int index);
- -

-Pops a table from the stack and -sets it as the new metatable for the value at the given -acceptable index. - - - - - -

lua_settable

-[-2, +0, e] -

void lua_settable (lua_State *L, int index);
- -

-Does the equivalent to t[k] = v, -where t is the value at the given valid index, -v is the value at the top of the stack, -and k is the value just below the top. - - -

-This function pops both the key and the value from the stack. -As in Lua, this function may trigger a metamethod -for the "newindex" event (see §2.8). - - - - - -

lua_settop

-[-?, +?, -] -

void lua_settop (lua_State *L, int index);
- -

-Accepts any acceptable index, or 0, -and sets the stack top to this index. -If the new top is larger than the old one, -then the new elements are filled with nil. -If index is 0, then all stack elements are removed. - - - - - -

lua_State

-
typedef struct lua_State lua_State;
- -

-Opaque structure that keeps the whole state of a Lua interpreter. -The Lua library is fully reentrant: -it has no global variables. -All information about a state is kept in this structure. - - -

-A pointer to this state must be passed as the first argument to -every function in the library, except to lua_newstate, -which creates a Lua state from scratch. - - - - - -

lua_status

-[-0, +0, -] -

int lua_status (lua_State *L);
- -

-Returns the status of the thread L. - - -

-The status can be 0 for a normal thread, -an error code if the thread finished its execution with an error, -or LUA_YIELD if the thread is suspended. - - - - - -

lua_toboolean

-[-0, +0, -] -

int lua_toboolean (lua_State *L, int index);
- -

-Converts the Lua value at the given acceptable index to a C boolean -value (0 or 1). -Like all tests in Lua, -lua_toboolean returns 1 for any Lua value -different from false and nil; -otherwise it returns 0. -It also returns 0 when called with a non-valid index. -(If you want to accept only actual boolean values, -use lua_isboolean to test the value's type.) - - - - - -

lua_tocfunction

-[-0, +0, -] -

lua_CFunction lua_tocfunction (lua_State *L, int index);
- -

-Converts a value at the given acceptable index to a C function. -That value must be a C function; -otherwise, returns NULL. - - - - - -

lua_tointeger

-[-0, +0, -] -

lua_Integer lua_tointeger (lua_State *L, int index);
- -

-Converts the Lua value at the given acceptable index -to the signed integral type lua_Integer. -The Lua value must be a number or a string convertible to a number -(see §2.2.1); -otherwise, lua_tointeger returns 0. - - -

-If the number is not an integer, -it is truncated in some non-specified way. - - - - - -

lua_tolstring

-[-0, +0, m] -

const char *lua_tolstring (lua_State *L, int index, size_t *len);
- -

-Converts the Lua value at the given acceptable index to a C string. -If len is not NULL, -it also sets *len with the string length. -The Lua value must be a string or a number; -otherwise, the function returns NULL. -If the value is a number, -then lua_tolstring also -changes the actual value in the stack to a string. -(This change confuses lua_next -when lua_tolstring is applied to keys during a table traversal.) - - -

-lua_tolstring returns a fully aligned pointer -to a string inside the Lua state. -This string always has a zero ('\0') -after its last character (as in C), -but can contain other zeros in its body. -Because Lua has garbage collection, -there is no guarantee that the pointer returned by lua_tolstring -will be valid after the corresponding value is removed from the stack. - - - - - -

lua_tonumber

-[-0, +0, -] -

lua_Number lua_tonumber (lua_State *L, int index);
- -

-Converts the Lua value at the given acceptable index -to the C type lua_Number (see lua_Number). -The Lua value must be a number or a string convertible to a number -(see §2.2.1); -otherwise, lua_tonumber returns 0. - - - - - -

const void *lua_topointer (lua_State *L, int index);
- -

-Converts the value at the given acceptable index to a generic -C pointer (void*). -The value can be a userdata, a table, a thread, or a function; -otherwise, lua_topointer returns NULL. -Different objects will give different pointers. -There is no way to convert the pointer back to its original value. - - -

-Typically this function is used only for debug information. - - - - - -

lua_tostring

lua_touserdata

-[-0, +0, -] -

void *lua_touserdata (lua_State *L, int index);
- -

-If the value at the given acceptable index is a full userdata, -returns its block address. -If the value is a light userdata, -returns its pointer. -Otherwise, returns NULL. - - - - - -

lua_type

-[-0, +0, -] -

int lua_type (lua_State *L, int index);
- -

-Returns the type of the value in the given acceptable index, -or LUA_TNONE for a non-valid index -(that is, an index to an "empty" stack position). -The types returned by lua_type are coded by the following constants -defined in lua.h: -LUA_TNIL, -LUA_TNUMBER, -LUA_TBOOLEAN, -LUA_TSTRING, -LUA_TTABLE, -LUA_TFUNCTION, -LUA_TUSERDATA, -LUA_TTHREAD, -and -LUA_TLIGHTUSERDATA. - - - - - -

-                           void* ud);
- -

-The type of the writer function used by lua_dump. -Every time it produces another piece of chunk, -lua_dump calls the writer, -passing along the buffer to be written (p), -its size (sz), -and the data parameter supplied to lua_dump. - - -

-The writer returns an error code: -0 means no errors; -any other value means an error and stops lua_dump from -calling the writer again. - - - - - -

lua_xmove

-[-?, +?, -] -

void lua_xmove (lua_State *from, lua_State *to, int n);
- -

-Exchange values between different threads of the same global state. - - -

-This function pops n values from the stack from, -and pushes them onto the stack to. - - - - - -

lua_yield

-[-?, +?, -] -

int lua_yield  (lua_State *L, int nresults);
- -

-Yields a coroutine. - - -

-This function should only be called as the -return expression of a C function, as follows: - -

-     return lua_yield (L, nresults);
-

-When a C function calls lua_yield in that way, -the running coroutine suspends its execution, -and the call to lua_resume that started this coroutine returns. -The parameter nresults is the number of values from the stack -that are passed as results to lua_resume. - - - - - - - -

3.8 - The Debug Interface

- -

-Lua has no built-in debugging facilities. -Instead, it offers a special interface -by means of functions and hooks. -This interface allows the construction of different -kinds of debuggers, profilers, and other tools -that need "inside information" from the interpreter. - - - -

lua_Debug

-
typedef struct lua_Debug {
-  int event;
-  const char *name;           /* (n) */
-  const char *namewhat;       /* (n) */
-  const char *what;           /* (S) */
-  const char *source;         /* (S) */
-  int currentline;            /* (l) */
-  int nups;                   /* (u) number of upvalues */
-  int linedefined;            /* (S) */
-  int lastlinedefined;        /* (S) */
-  char short_src[LUA_IDSIZE]; /* (S) */
-  /* private part */
-  other fields
-} lua_Debug;
- -

-A structure used to carry different pieces of -information about an active function. -lua_getstack fills only the private part -of this structure, for later use. -To fill the other fields of lua_Debug with useful information, -call lua_getinfo. - - -

-The fields of lua_Debug have the following meaning: - -

    - -
  • source: -If the function was defined in a string, -then source is that string. -If the function was defined in a file, -then source starts with a '@' followed by the file name. -
    • - -
  • short_src: -a "printable" version of source, to be used in error messages. -
    • - -
  • linedefined: -the line number where the definition of the function starts. -
    • - -
  • lastlinedefined: -the line number where the definition of the function ends. -
    • - -
  • what: -the string "Lua" if the function is a Lua function, -"C" if it is a C function, -"main" if it is the main part of a chunk, -and "tail" if it was a function that did a tail call. -In the latter case, -Lua has no other information about the function. -
    • - -
  • currentline: -the current line where the given function is executing. -When no line information is available, -currentline is set to -1. -
    • - -
  • name: -a reasonable name for the given function. -Because functions in Lua are first-class values, -they do not have a fixed name: -some functions can be the value of multiple global variables, -while others can be stored only in a table field. -The lua_getinfo function checks how the function was -called to find a suitable name. -If it cannot find a name, -then name is set to NULL. -
    • - -
  • namewhat: -explains the name field. -The value of namewhat can be -"global", "local", "method", -"field", "upvalue", or "" (the empty string), -according to how the function was called. -(Lua uses the empty string when no other option seems to apply.) -
    • - -
  • nups: -the number of upvalues of the function. -
    • - -
- - - - -

lua_gethook

-[-0, +0, -] -

lua_Hook lua_gethook (lua_State *L);
- -

-Returns the current hook function. - - - - - -

lua_gethookcount

-[-0, +0, -] -

int lua_gethookcount (lua_State *L);
- -

-Returns the current hook count. - - - - - -

lua_gethookmask

-[-0, +0, -] -

int lua_gethookmask (lua_State *L);
- -

-Returns the current hook mask. - - - - - -

lua_getinfo

-[-(0|1), +(0|1|2), m] -

int lua_getinfo (lua_State *L, const char *what, lua_Debug *ar);
- -

-Returns information about a specific function or function invocation. - - -

-To get information about a function invocation, -the parameter ar must be a valid activation record that was -filled by a previous call to lua_getstack or -given as argument to a hook (see lua_Hook). - - -

-To get information about a function you push it onto the stack -and start the what string with the character '>'. -(In that case, -lua_getinfo pops the function in the top of the stack.) -For instance, to know in which line a function f was defined, -you can write the following code: - -

-     lua_Debug ar;
-     lua_getfield(L, LUA_GLOBALSINDEX, "f");  /* get global 'f' */
-     lua_getinfo(L, ">S", &ar);
-     printf("%d\n", ar.linedefined);
-
- -

-Each character in the string what -selects some fields of the structure ar to be filled or -a value to be pushed on the stack: - -

    - -
  • 'n': fills in the field name and namewhat; -
    • - -
  • 'S': -fills in the fields source, short_src, -linedefined, lastlinedefined, and what; -
    • - -
  • 'l': fills in the field currentline; -
    • - -
  • 'u': fills in the field nups; -
    • - -
  • 'f': -pushes onto the stack the function that is -running at the given level; -
    • - -
  • 'L': -pushes onto the stack a table whose indices are the -numbers of the lines that are valid on the function. -(A valid line is a line with some associated code, -that is, a line where you can put a break point. -Non-valid lines include empty lines and comments.) -
    • - -
- -

-This function returns 0 on error -(for instance, an invalid option in what). - - - - - -

lua_getlocal

-[-0, +(0|1), -] -

const char *lua_getlocal (lua_State *L, lua_Debug *ar, int n);
- -

-Gets information about a local variable of a given activation record. -The parameter ar must be a valid activation record that was -filled by a previous call to lua_getstack or -given as argument to a hook (see lua_Hook). -The index n selects which local variable to inspect -(1 is the first parameter or active local variable, and so on, -until the last active local variable). -lua_getlocal pushes the variable's value onto the stack -and returns its name. - - -

-Variable names starting with '(' (open parentheses) -represent internal variables -(loop control variables, temporaries, and C function locals). - - -

-Returns NULL (and pushes nothing) -when the index is greater than -the number of active local variables. - - - - - -

lua_getstack

-[-0, +0, -] -

int lua_getstack (lua_State *L, int level, lua_Debug *ar);
- -

-Get information about the interpreter runtime stack. - - -

-This function fills parts of a lua_Debug structure with -an identification of the activation record -of the function executing at a given level. -Level 0 is the current running function, -whereas level n+1 is the function that has called level n. -When there are no errors, lua_getstack returns 1; -when called with a level greater than the stack depth, -it returns 0. - - - - - -

lua_getupvalue

-[-0, +(0|1), -] -

const char *lua_getupvalue (lua_State *L, int funcindex, int n);
- -

-Gets information about a closure's upvalue. -(For Lua functions, -upvalues are the external local variables that the function uses, -and that are consequently included in its closure.) -lua_getupvalue gets the index n of an upvalue, -pushes the upvalue's value onto the stack, -and returns its name. -funcindex points to the closure in the stack. -(Upvalues have no particular order, -as they are active through the whole function. -So, they are numbered in an arbitrary order.) - - -

-Returns NULL (and pushes nothing) -when the index is greater than the number of upvalues. -For C functions, this function uses the empty string "" -as a name for all upvalues. - - - - - -

lua_Hook

-
typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);
- -

-Type for debugging hook functions. - - -

-Whenever a hook is called, its ar argument has its field -event set to the specific event that triggered the hook. -Lua identifies these events with the following constants: -LUA_HOOKCALL, LUA_HOOKRET, -LUA_HOOKTAILRET, LUA_HOOKLINE, -and LUA_HOOKCOUNT. -Moreover, for line events, the field currentline is also set. -To get the value of any other field in ar, -the hook must call lua_getinfo. -For return events, event can be LUA_HOOKRET, -the normal value, or LUA_HOOKTAILRET. -In the latter case, Lua is simulating a return from -a function that did a tail call; -in this case, it is useless to call lua_getinfo. - - -

-While Lua is running a hook, it disables other calls to hooks. -Therefore, if a hook calls back Lua to execute a function or a chunk, -this execution occurs without any calls to hooks. - - - - - -

lua_sethook

-[-0, +0, -] -

int lua_sethook (lua_State *L, lua_Hook f, int mask, int count);
- -

-Sets the debugging hook function. - - -

-Argument f is the hook function. -mask specifies on which events the hook will be called: -it is formed by a bitwise or of the constants -LUA_MASKCALL, -LUA_MASKRET, -LUA_MASKLINE, -and LUA_MASKCOUNT. -The count argument is only meaningful when the mask -includes LUA_MASKCOUNT. -For each event, the hook is called as explained below: - -

    - -
  • The call hook: is called when the interpreter calls a function. -The hook is called just after Lua enters the new function, -before the function gets its arguments. -
    • - -
  • The return hook: is called when the interpreter returns from a function. -The hook is called just before Lua leaves the function. -You have no access to the values to be returned by the function. -
    • - -
  • The line hook: is called when the interpreter is about to -start the execution of a new line of code, -or when it jumps back in the code (even to the same line). -(This event only happens while Lua is executing a Lua function.) -
    • - -
  • The count hook: is called after the interpreter executes every -count instructions. -(This event only happens while Lua is executing a Lua function.) -
    • - -
- -

-A hook is disabled by setting mask to zero. - - - - - -

lua_setlocal

-[-(0|1), +0, -] -

const char *lua_setlocal (lua_State *L, lua_Debug *ar, int n);
- -

-Sets the value of a local variable of a given activation record. -Parameters ar and n are as in lua_getlocal -(see lua_getlocal). -lua_setlocal assigns the value at the top of the stack -to the variable and returns its name. -It also pops the value from the stack. - - -

-Returns NULL (and pops nothing) -when the index is greater than -the number of active local variables. - - - - - -

lua_setupvalue

-[-(0|1), +0, -] -

const char *lua_setupvalue (lua_State *L, int funcindex, int n);
- -

-Sets the value of a closure's upvalue. -It assigns the value at the top of the stack -to the upvalue and returns its name. -It also pops the value from the stack. -Parameters funcindex and n are as in the lua_getupvalue -(see lua_getupvalue). - - -

-Returns NULL (and pops nothing) -when the index is greater than the number of upvalues. - - - - - - - -

4 - The Auxiliary Library

- -

- -The auxiliary library provides several convenient functions -to interface C with Lua. -While the basic API provides the primitive functions for all -interactions between C and Lua, -the auxiliary library provides higher-level functions for some -common tasks. - - -

-All functions from the auxiliary library -are defined in header file lauxlib.h and -have a prefix luaL_. - - -

-All functions in the auxiliary library are built on -top of the basic API, -and so they provide nothing that cannot be done with this API. - - -

-Several functions in the auxiliary library are used to -check C function arguments. -Their names are always luaL_check* or luaL_opt*. -All of these functions throw an error if the check is not satisfied. -Because the error message is formatted for arguments -(e.g., "bad argument #1"), -you should not use these functions for other stack values. - - - -

4.1 - Functions and Types

- -

-Here we list all functions and types from the auxiliary library -in alphabetical order. - - - -

luaL_addchar

-[-0, +0, m] -

void luaL_addchar (luaL_Buffer *B, char c);
- -

-Adds the character c to the buffer B -(see luaL_Buffer). - - - - - -

-[-0, +0, m] -

void luaL_addlstring (luaL_Buffer *B, const char *s, size_t l);
- -

-Adds the string pointed to by s with length l to -the buffer B -(see luaL_Buffer). -The string may contain embedded zeros. - - - - - -

luaL_addsize

-[-0, +0, m] -

void luaL_addsize (luaL_Buffer *B, size_t n);
- -

-Adds to the buffer B (see luaL_Buffer) -a string of length n previously copied to the -buffer area (see luaL_prepbuffer). - - - - - -

-[-0, +0, m] -

void luaL_addstring (luaL_Buffer *B, const char *s);
- -

-Adds the zero-terminated string pointed to by s -to the buffer B -(see luaL_Buffer). -The string may not contain embedded zeros. - - - - - -

luaL_addvalue

-[-1, +0, m] -

void luaL_addvalue (luaL_Buffer *B);
- -

-Adds the value at the top of the stack -to the buffer B -(see luaL_Buffer). -Pops the value. - - -

-This is the only function on string buffers that can (and must) -be called with an extra element on the stack, -which is the value to be added to the buffer. - - - - - -

luaL_argcheck

-[-0, +0, v] -

void luaL_argcheck (lua_State *L,
-                    int cond,
-                    int narg,
-                    const char *extramsg);
- -

-Checks whether cond is true. -If not, raises an error with the following message, -where func is retrieved from the call stack: - -

-     bad argument #<narg> to <func> (<extramsg>)
-
- - - - -

luaL_argerror

-[-0, +0, v] -

int luaL_argerror (lua_State *L, int narg, const char *extramsg);
- -

-Raises an error with the following message, -where func is retrieved from the call stack: - -

-     bad argument #<narg> to <func> (<extramsg>)
-
- -

-This function never returns, -but it is an idiom to use it in C functions -as return luaL_argerror(args). - - - - - -

luaL_Buffer

-
typedef struct luaL_Buffer luaL_Buffer;
- -

-Type for a string buffer. - - -

-A string buffer allows C code to build Lua strings piecemeal. -Its pattern of use is as follows: - -

    - -
  • First you declare a variable b of type luaL_Buffer.
    • - -
  • Then you initialize it with a call luaL_buffinit(L, &b).
    • - -
  • -Then you add string pieces to the buffer calling any of -the luaL_add* functions. -
    • - -
  • -You finish by calling luaL_pushresult(&b). -This call leaves the final string on the top of the stack. -
    • - -
- -

-During its normal operation, -a string buffer uses a variable number of stack slots. -So, while using a buffer, you cannot assume that you know where -the top of the stack is. -You can use the stack between successive calls to buffer operations -as long as that use is balanced; -that is, -when you call a buffer operation, -the stack is at the same level -it was immediately after the previous buffer operation. -(The only exception to this rule is luaL_addvalue.) -After calling luaL_pushresult the stack is back to its -level when the buffer was initialized, -plus the final string on its top. - - - - - -

luaL_buffinit

-[-0, +0, -] -

void luaL_buffinit (lua_State *L, luaL_Buffer *B);
- -

luaL_callmeta

-[-0, +(0|1), e] -

int luaL_callmeta (lua_State *L, int obj, const char *e);
- -

-Calls a metamethod. - - -

-If the object at index obj has a metatable and this -metatable has a field e, -this function calls this field and passes the object as its only argument. -In this case this function returns 1 and pushes onto the -stack the value returned by the call. -If there is no metatable or no metamethod, -this function returns 0 (without pushing any value on the stack). - - - - - -

luaL_checkany

-[-0, +0, v] -

void luaL_checkany (lua_State *L, int narg);

- -

-Checks whether the function argument narg is a number -and returns this number cast to a lua_Integer. - - - - - -

-[-0, +0, v] -

const char *luaL_checklstring (lua_State *L, int narg, size_t *l);
- -

-Checks whether the function argument narg is a string -and returns this string; -if l is not NULL fills *l -with the string's length. - - -

-This function uses lua_tolstring to get its result, -so all conversions and caveats of that function apply here. - - - - - -

luaL_checknumber

-[-0, +0, v] -

lua_Number luaL_checknumber (lua_State *L, int narg);
- -

-Checks whether the function argument narg is a number -and returns this number. - - - - - -

luaL_checkoption

-[-0, +0, v] -

int luaL_checkoption (lua_State *L,
-                      int narg,
-                      const char *def,
-                      const char *const lst[]);
- -

-Checks whether the function argument narg is a string and -searches for this string in the array lst -(which must be NULL-terminated). -Returns the index in the array where the string was found. -Raises an error if the argument is not a string or -if the string cannot be found. - - -

-If def is not NULL, -the function uses def as a default value when -there is no argument narg or if this argument is nil. - - -

-This is a useful function for mapping strings to C enums. -(The usual convention in Lua libraries is -to use strings instead of numbers to select options.) - - - - - -

luaL_checkstack

-[-0, +0, v] -

void luaL_checkstack (lua_State *L, int sz, const char *msg);
- -

const char *luaL_checkstring (lua_State *L, int narg);
- -

-Checks whether the function argument narg is a string -and returns this string. - - -

luaL_dostring

-[-0, +?, m] -

int luaL_dostring (lua_State *L, const char *str);
- -

luaL_error

-[-0, +0, v] -

int luaL_error (lua_State *L, const char *fmt, ...);
- -

-This function never returns, -but it is an idiom to use it in C functions -as return luaL_error(args). - - - - - -

luaL_getmetafield

-[-0, +(0|1), m] -

int luaL_getmetafield (lua_State *L, int obj, const char *e);
- -

-Pushes onto the stack the field e from the metatable -of the object at index obj. -If the object does not have a metatable, -or if the metatable does not have this field, -returns 0 and pushes nothing. - - - - - -

luaL_getmetatable

-[-0, +1, -] -

void luaL_getmetatable (lua_State *L, const char *tname);
- -

-                     const char *name);
- -

-Loads a buffer as a Lua chunk. -This function uses lua_load to load the chunk in the -buffer pointed to by buff with size sz. - - -

luaL_loadfile

-[-0, +1, m] -

int luaL_loadfile (lua_State *L, const char *filename);
- -

luaL_newstate

-[-0, +0, -] -

lua_State *luaL_newstate (void);
- -

-                             size_t *l);
- -

-If the function argument narg is a string, -returns this string. -If this argument is absent or is nil, -returns d. -Otherwise, raises an error. - - -

-If l is not NULL, -fills the position *l with the results's length. - - - - - -

luaL_optnumber

-[-0, +0, v] -

lua_Number luaL_optnumber (lua_State *L, int narg, lua_Number d);
- -

-If the function argument narg is a number, -returns this number. -If this argument is absent or is nil, -returns d. -Otherwise, raises an error. - - - - - -

luaL_optstring

-[-0, +0, v] -

const char *luaL_optstring (lua_State *L,
-                            int narg,
-                            const char *d);
- -

-If the function argument narg is a string, -returns this string. -If this argument is absent or is nil, -returns d. -Otherwise, raises an error. - - - - - -

luaL_prepbuffer

-[-0, +0, -] -

char *luaL_prepbuffer (luaL_Buffer *B);
- -

-Returns an address to a space of size LUAL_BUFFERSIZE -where you can copy a string to be added to buffer B -(see luaL_Buffer). -After copying the string into this space you must call -luaL_addsize with the size of the string to actually add -it to the buffer. - - - - - -

luaL_pushresult

-[-?, +1, m] -

void luaL_pushresult (luaL_Buffer *B);
- -

-Finishes the use of buffer B leaving the final string on -the top of the stack. - - - - - -

luaL_ref

-[-1, +0, m] -

int luaL_ref (lua_State *L, int t);
- -

-Creates and returns a reference, -in the table at index t, -for the object at the top of the stack (and pops the object). - - -

-A reference is a unique integer key. -As long as you do not manually add integer keys into table t, -luaL_ref ensures the uniqueness of the key it returns. -You can retrieve an object referred by reference r -by calling lua_rawgeti(L, t, r). -Function luaL_unref frees a reference and its associated object. - - -

-If the object at the top of the stack is nil, -luaL_ref returns the constant LUA_REFNIL. -The constant LUA_NOREF is guaranteed to be different -from any reference returned by luaL_ref. - - - - - -

luaL_Reg

-
typedef struct luaL_Reg {
-  const char *name;
-  lua_CFunction func;
-} luaL_Reg;
- -

-Type for arrays of functions to be registered by -luaL_register. -name is the function name and func is a pointer to -the function. -Any array of luaL_Reg must end with an sentinel entry -in which both name and func are NULL. - - - - - -

luaL_register

-[-(0|1), +1, m] -

void luaL_register (lua_State *L,
-                    const char *libname,
-                    const luaL_Reg *l);
- -

-Opens a library. - - -

-When called with libname equal to NULL, -it simply registers all functions in the list l -(see luaL_Reg) into the table on the top of the stack. - - -

-When called with a non-null libname, -luaL_register creates a new table t, -sets it as the value of the global variable libname, -sets it as the value of package.loaded[libname], -and registers on it all functions in the list l. -If there is a table in package.loaded[libname] or in -variable libname, -reuses this table instead of creating a new one. - - -

-In any case the function leaves the table -on the top of the stack. - - - - - -

luaL_typename

-[-0, +0, -] -

const char *luaL_typename (lua_State *L, int index);
- -

-Returns the name of the type of the value at the given index. - - - - - -

luaL_typerror

-[-0, +0, v] -

int luaL_typerror (lua_State *L, int narg, const char *tname);
- -

-Generates an error with a message like the following: - -

-     location: bad argument narg to 'func' (tname expected, got rt)
-

-where location is produced by luaL_where, -func is the name of the current function, -and rt is the type name of the actual argument. - - - - - -

luaL_unref

-[-0, +0, -] -

void luaL_unref (lua_State *L, int t, int ref);
- -

-Releases reference ref from the table at index t -(see luaL_ref). -The entry is removed from the table, -so that the referred object can be collected. -The reference ref is also freed to be used again. - - -

-If ref is LUA_NOREF or LUA_REFNIL, -luaL_unref does nothing. - - - - - -

luaL_where

-[-0, +1, m] -

void luaL_where (lua_State *L, int lvl);
- -

-Pushes onto the stack a string identifying the current position -of the control at level lvl in the call stack. -Typically this string has the following format: - -

-     chunkname:currentline:
-

-Level 0 is the running function, -level 1 is the function that called the running function, -etc. - - -

-This function is used to build a prefix for error messages. - - - - - - - -

5 - Standard Libraries

- -

-The standard Lua libraries provide useful functions -that are implemented directly through the C API. -Some of these functions provide essential services to the language -(e.g., type and getmetatable); -others provide access to "outside" services (e.g., I/O); -and others could be implemented in Lua itself, -but are quite useful or have critical performance requirements that -deserve an implementation in C (e.g., table.sort). - - -

-All libraries are implemented through the official C API -and are provided as separate C modules. -Currently, Lua has the following standard libraries: - -

    - -
  • basic library, which includes the coroutine sub-library;
    • - -
  • package library;
    • - -
  • string manipulation;
    • - -
  • table manipulation;
    • - -
  • mathematical functions (sin, log, etc.);
    • - -
  • input and output;
    • - -
  • operating system facilities;
    • - -
  • debug facilities.
    • - -

-Except for the basic and package libraries, -each library provides all its functions as fields of a global table -or as methods of its objects. - - -

-To have access to these libraries, -the C host program should call the luaL_openlibs function, -which opens all standard libraries. -Alternatively, -it can open them individually by calling -luaopen_base (for the basic library), -luaopen_package (for the package library), -luaopen_string (for the string library), -luaopen_table (for the table library), -luaopen_math (for the mathematical library), -luaopen_io (for the I/O library), -luaopen_os (for the Operating System library), -and luaopen_debug (for the debug library). -These functions are declared in lualib.h -and should not be called directly: -you must call them like any other Lua C function, -e.g., by using lua_call. - - - -

5.1 - Basic Functions

- -

-The basic library provides some core functions to Lua. -If you do not include this library in your application, -you should check carefully whether you need to provide -implementations for some of its facilities. - - -

-

assert (v [, message])

-Issues an error when -the value of its argument v is false (i.e., nil or false); -otherwise, returns all its arguments. -message is an error message; -when absent, it defaults to "assertion failed!" - - - - -

-

collectgarbage ([opt [, arg]])

- - -

-This function is a generic interface to the garbage collector. -It performs different functions according to its first argument, opt: - -

    - -
  • "collect": -performs a full garbage-collection cycle. -This is the default option. -
    • - -
  • "stop": -stops the garbage collector. -
    • - -
  • "restart": -restarts the garbage collector. -
    • - -
  • "count": -returns the total memory in use by Lua (in Kbytes). -
    • - -
  • "step": -performs a garbage-collection step. -The step "size" is controlled by arg -(larger values mean more steps) in a non-specified way. -If you want to control the step size -you must experimentally tune the value of arg. -Returns true if the step finished a collection cycle. -
    • - -
  • "setpause": -sets arg as the new value for the pause of -the collector (see §2.10). -Returns the previous value for pause. -
    • - -
  • "setstepmul": -sets arg as the new value for the step multiplier of -the collector (see §2.10). -Returns the previous value for step. -
    • - -
- - - -

-

dofile ([filename])

-Opens the named file and executes its contents as a Lua chunk. -When called without arguments, -dofile executes the contents of the standard input (stdin). -Returns all values returned by the chunk. -In case of errors, dofile propagates the error -to its caller (that is, dofile does not run in protected mode). - - - - -

-

error (message [, level])

-Terminates the last protected function called -and returns message as the error message. -Function error never returns. - - -

-Usually, error adds some information about the error position -at the beginning of the message. -The level argument specifies how to get the error position. -With level 1 (the default), the error position is where the -error function was called. -Level 2 points the error to where the function -that called error was called; and so on. -Passing a level 0 avoids the addition of error position information -to the message. - - - - -

-

_G

-A global variable (not a function) that -holds the global environment (that is, _G._G = _G). -Lua itself does not use this variable; -changing its value does not affect any environment, -nor vice-versa. -(Use setfenv to change environments.) - - - - -

-

getfenv ([f])

-Returns the current environment in use by the function. -f can be a Lua function or a number -that specifies the function at that stack level: -Level 1 is the function calling getfenv. -If the given function is not a Lua function, -or if f is 0, -getfenv returns the global environment. -The default for f is 1. - - - - -

-

getmetatable (object)

- - -

-If object does not have a metatable, returns nil. -Otherwise, -if the object's metatable has a "__metatable" field, -returns the associated value. -Otherwise, returns the metatable of the given object. - - - - -

-

ipairs (t)

- - -

-Returns three values: an iterator function, the table t, and 0, -so that the construction - -

-     for i,v in ipairs(t) do body end
-

-will iterate over the pairs (1,t[1]), (2,t[2]), ···, -up to the first integer key absent from the table. - - - - -

-

load (func [, chunkname])

- - -

-Loads a chunk using function func to get its pieces. -Each call to func must return a string that concatenates -with previous results. -A return of an empty string, nil, or no value signals the end of the chunk. - - -

-If there are no errors, -returns the compiled chunk as a function; -otherwise, returns nil plus the error message. -The environment of the returned function is the global environment. - - -

-chunkname is used as the chunk name for error messages -and debug information. -When absent, -it defaults to "=(load)". - - - - -

-

loadfile ([filename])

- - -

-Similar to load, -but gets the chunk from file filename -or from the standard input, -if no file name is given. - - - - -

-

loadstring (string [, chunkname])

- - -

-Similar to load, -but gets the chunk from the given string. - - -

-To load and run a given string, use the idiom - -

-     assert(loadstring(s))()
-
- -

-When absent, -chunkname defaults to the given string. - - - - -

-

next (table [, index])

- - -

-Allows a program to traverse all fields of a table. -Its first argument is a table and its second argument -is an index in this table. -next returns the next index of the table -and its associated value. -When called with nil as its second argument, -next returns an initial index -and its associated value. -When called with the last index, -or with nil in an empty table, -next returns nil. -If the second argument is absent, then it is interpreted as nil. -In particular, -you can use next(t) to check whether a table is empty. - - -

-The order in which the indices are enumerated is not specified, -even for numeric indices. -(To traverse a table in numeric order, -use a numerical for or the ipairs function.) - - -

-The behavior of next is undefined if, -during the traversal, -you assign any value to a non-existent field in the table. -You may however modify existing fields. -In particular, you may clear existing fields. - - - - -

-

pairs (t)

- - -

-Returns three values: the next function, the table t, and nil, -so that the construction - -

-     for k,v in pairs(t) do body end
-

-will iterate over all key–value pairs of table t. - - -

-See function next for the caveats of modifying -the table during its traversal. - - - - -

-

pcall (f, arg1, ···)

- - -

-Calls function f with -the given arguments in protected mode. -This means that any error inside f is not propagated; -instead, pcall catches the error -and returns a status code. -Its first result is the status code (a boolean), -which is true if the call succeeds without errors. -In such case, pcall also returns all results from the call, -after this first result. -In case of any error, pcall returns false plus the error message. - - - - -

-

print (···)

-Receives any number of arguments, -and prints their values to stdout, -using the tostring function to convert them to strings. -print is not intended for formatted output, -but only as a quick way to show a value, -typically for debugging. -For formatted output, use string.format. - - - - -

-

rawequal (v1, v2)

-Checks whether v1 is equal to v2, -without invoking any metamethod. -Returns a boolean. - - - - -

-

rawget (table, index)

-Gets the real value of table[index], -without invoking any metamethod. -table must be a table; -index may be any value. - - - - -

-

rawset (table, index, value)

-Sets the real value of table[index] to value, -without invoking any metamethod. -table must be a table, -index any value different from nil, -and value any Lua value. - - -

-This function returns table. - - - - -

-

select (index, ···)

- - -

-If index is a number, -returns all arguments after argument number index. -Otherwise, index must be the string "#", -and select returns the total number of extra arguments it received. - - - - -

-

setfenv (f, table)

- - -

-Sets the environment to be used by the given function. -f can be a Lua function or a number -that specifies the function at that stack level: -Level 1 is the function calling setfenv. -setfenv returns the given function. - - -

-As a special case, when f is 0 setfenv changes -the environment of the running thread. -In this case, setfenv returns no values. - - - - -

-

setmetatable (table, metatable)

- - -

-Sets the metatable for the given table. -(You cannot change the metatable of other types from Lua, only from C.) -If metatable is nil, -removes the metatable of the given table. -If the original metatable has a "__metatable" field, -raises an error. - - -

-This function returns table. - - - - -

-

tonumber (e [, base])

-Tries to convert its argument to a number. -If the argument is already a number or a string convertible -to a number, then tonumber returns this number; -otherwise, it returns nil. - - -

-An optional argument specifies the base to interpret the numeral. -The base may be any integer between 2 and 36, inclusive. -In bases above 10, the letter 'A' (in either upper or lower case) -represents 10, 'B' represents 11, and so forth, -with 'Z' representing 35. -In base 10 (the default), the number can have a decimal part, -as well as an optional exponent part (see §2.1). -In other bases, only unsigned integers are accepted. - - - - -

-

tostring (e)

-Receives an argument of any type and -converts it to a string in a reasonable format. -For complete control of how numbers are converted, -use string.format. - - -

-If the metatable of e has a "__tostring" field, -then tostring calls the corresponding value -with e as argument, -and uses the result of the call as its result. - - - - -

-

type (v)

-Returns the type of its only argument, coded as a string. -The possible results of this function are -"nil" (a string, not the value nil), -"number", -"string", -"boolean", -"table", -"function", -"thread", -and "userdata". - - - - -

-

unpack (list [, i [, j]])

-Returns the elements from the given table. -This function is equivalent to - -
-     return list[i], list[i+1], ···, list[j]
-

-except that the above code can be written only for a fixed number -of elements. -By default, i is 1 and j is the length of the list, -as defined by the length operator (see §2.5.5). - - - - -

-

_VERSION

-A global variable (not a function) that -holds a string containing the current interpreter version. -The current contents of this variable is "Lua 5.1". - - - - -

-

xpcall (f, err)

- - -

-This function is similar to pcall, -except that you can set a new error handler. - - -

-xpcall calls function f in protected mode, -using err as the error handler. -Any error inside f is not propagated; -instead, xpcall catches the error, -calls the err function with the original error object, -and returns a status code. -Its first result is the status code (a boolean), -which is true if the call succeeds without errors. -In this case, xpcall also returns all results from the call, -after this first result. -In case of any error, -xpcall returns false plus the result from err. - - - - - - - -

5.2 - Coroutine Manipulation

- -

-The operations related to coroutines comprise a sub-library of -the basic library and come inside the table coroutine. -See §2.11 for a general description of coroutines. - - -

-

coroutine.create (f)

- - -

-Creates a new coroutine, with body f. -f must be a Lua function. -Returns this new coroutine, -an object with type "thread". - - - - -

-

coroutine.resume (co [, val1, ···])

- - -

-Starts or continues the execution of coroutine co. -The first time you resume a coroutine, -it starts running its body. -The values val1, ··· are passed -as the arguments to the body function. -If the coroutine has yielded, -resume restarts it; -the values val1, ··· are passed -as the results from the yield. - - -

-If the coroutine runs without any errors, -resume returns true plus any values passed to yield -(if the coroutine yields) or any values returned by the body function -(if the coroutine terminates). -If there is any error, -resume returns false plus the error message. - - - - -

-

coroutine.running ()

- - -

-Returns the running coroutine, -or nil when called by the main thread. - - - - -

-

coroutine.status (co)

- - -

-Returns the status of coroutine co, as a string: -"running", -if the coroutine is running (that is, it called status); -"suspended", if the coroutine is suspended in a call to yield, -or if it has not started running yet; -"normal" if the coroutine is active but not running -(that is, it has resumed another coroutine); -and "dead" if the coroutine has finished its body function, -or if it has stopped with an error. - - - - -

-

coroutine.wrap (f)

- - -

-Creates a new coroutine, with body f. -f must be a Lua function. -Returns a function that resumes the coroutine each time it is called. -Any arguments passed to the function behave as the -extra arguments to resume. -Returns the same values returned by resume, -except the first boolean. -In case of error, propagates the error. - - - - -

-

coroutine.yield (···)

- - -

-Suspends the execution of the calling coroutine. -The coroutine cannot be running a C function, -a metamethod, or an iterator. -Any arguments to yield are passed as extra results to resume. - - - - - - - -

5.3 - Modules

- -

-The package library provides basic -facilities for loading and building modules in Lua. -It exports two of its functions directly in the global environment: -require and module. -Everything else is exported in a table package. - - -

-

module (name [, ···])

- - -

-Creates a module. -If there is a table in package.loaded[name], -this table is the module. -Otherwise, if there is a global table t with the given name, -this table is the module. -Otherwise creates a new table t and -sets it as the value of the global name and -the value of package.loaded[name]. -This function also initializes t._NAME with the given name, -t._M with the module (t itself), -and t._PACKAGE with the package name -(the full module name minus last component; see below). -Finally, module sets t as the new environment -of the current function and the new value of package.loaded[name], -so that require returns t. - - -

-If name is a compound name -(that is, one with components separated by dots), -module creates (or reuses, if they already exist) -tables for each component. -For instance, if name is a.b.c, -then module stores the module table in field c of -field b of global a. - - -

-This function can receive optional options after -the module name, -where each option is a function to be applied over the module. - - - - -

-

require (modname)

- - -

-Loads the given module. -The function starts by looking into the package.loaded table -to determine whether modname is already loaded. -If it is, then require returns the value stored -at package.loaded[modname]. -Otherwise, it tries to find a loader for the module. - - -

-To find a loader, -require is guided by the package.loaders array. -By changing this array, -we can change how require looks for a module. -The following explanation is based on the default configuration -for package.loaders. - - -

-First require queries package.preload[modname]. -If it has a value, -this value (which should be a function) is the loader. -Otherwise require searches for a Lua loader using the -path stored in package.path. -If that also fails, it searches for a C loader using the -path stored in package.cpath. -If that also fails, -it tries an all-in-one loader (see package.loaders). - - -

-Once a loader is found, -require calls the loader with a single argument, modname. -If the loader returns any value, -require assigns the returned value to package.loaded[modname]. -If the loader returns no value and -has not assigned any value to package.loaded[modname], -then require assigns true to this entry. -In any case, require returns the -final value of package.loaded[modname]. - - -

-If there is any error loading or running the module, -or if it cannot find any loader for the module, -then require signals an error. - - - - -

-

package.cpath

- - -

-The path used by require to search for a C loader. - - -

-Lua initializes the C path package.cpath in the same way -it initializes the Lua path package.path, -using the environment variable LUA_CPATH -or a default path defined in luaconf.h. - - - - -

- -

package.loaded

- - -

-A table used by require to control which -modules are already loaded. -When you require a module modname and -package.loaded[modname] is not false, -require simply returns the value stored there. - - - - -

-

package.loaders

- - -

-A table used by require to control how to load modules. - - -

-Each entry in this table is a searcher function. -When looking for a module, -require calls each of these searchers in ascending order, -with the module name (the argument given to require) as its -sole parameter. -The function can return another function (the module loader) -or a string explaining why it did not find that module -(or nil if it has nothing to say). -Lua initializes this table with four functions. - - -

-The first searcher simply looks for a loader in the -package.preload table. - - -

-The second searcher looks for a loader as a Lua library, -using the path stored at package.path. -A path is a sequence of templates separated by semicolons. -For each template, -the searcher will change each interrogation -mark in the template by filename, -which is the module name with each dot replaced by a -"directory separator" (such as "/" in Unix); -then it will try to open the resulting file name. -So, for instance, if the Lua path is the string - -

-     "./?.lua;./?.lc;/usr/local/?/init.lua"
-

-the search for a Lua file for module foo -will try to open the files -./foo.lua, ./foo.lc, and -/usr/local/foo/init.lua, in that order. - - -

-The third searcher looks for a loader as a C library, -using the path given by the variable package.cpath. -For instance, -if the C path is the string - -

-     "./?.so;./?.dll;/usr/local/?/init.so"
-

-the searcher for module foo -will try to open the files ./foo.so, ./foo.dll, -and /usr/local/foo/init.so, in that order. -Once it finds a C library, -this searcher first uses a dynamic link facility to link the -application with the library. -Then it tries to find a C function inside the library to -be used as the loader. -The name of this C function is the string "luaopen_" -concatenated with a copy of the module name where each dot -is replaced by an underscore. -Moreover, if the module name has a hyphen, -its prefix up to (and including) the first hyphen is removed. -For instance, if the module name is a.v1-b.c, -the function name will be luaopen_b_c. - - -

-The fourth searcher tries an all-in-one loader. -It searches the C path for a library for -the root name of the given module. -For instance, when requiring a.b.c, -it will search for a C library for a. -If found, it looks into it for an open function for -the submodule; -in our example, that would be luaopen_a_b_c. -With this facility, a package can pack several C submodules -into one single library, -with each submodule keeping its original open function. - - - - -

-

package.loadlib (libname, funcname)

- - -

-Dynamically links the host program with the C library libname. -Inside this library, looks for a function funcname -and returns this function as a C function. -(So, funcname must follow the protocol (see lua_CFunction)). - - -

-This is a low-level function. -It completely bypasses the package and module system. -Unlike require, -it does not perform any path searching and -does not automatically adds extensions. -libname must be the complete file name of the C library, -including if necessary a path and extension. -funcname must be the exact name exported by the C library -(which may depend on the C compiler and linker used). - - -

-This function is not supported by ANSI C. -As such, it is only available on some platforms -(Windows, Linux, Mac OS X, Solaris, BSD, -plus other Unix systems that support the dlfcn standard). - - - - -

-

package.path

- - -

-The path used by require to search for a Lua loader. - - -

-At start-up, Lua initializes this variable with -the value of the environment variable LUA_PATH or -with a default path defined in luaconf.h, -if the environment variable is not defined. -Any ";;" in the value of the environment variable -is replaced by the default path. - - - - -

-

package.preload

- - -

-A table to store loaders for specific modules -(see require). - - - - -

-

package.seeall (module)

- - -

-Sets a metatable for module with -its __index field referring to the global environment, -so that this module inherits values -from the global environment. -To be used as an option to function module. - - - - - - - -

5.4 - String Manipulation

- -

-This library provides generic functions for string manipulation, -such as finding and extracting substrings, and pattern matching. -When indexing a string in Lua, the first character is at position 1 -(not at 0, as in C). -Indices are allowed to be negative and are interpreted as indexing backwards, -from the end of the string. -Thus, the last character is at position -1, and so on. - - -

-The string library provides all its functions inside the table -string. -It also sets a metatable for strings -where the __index field points to the string table. -Therefore, you can use the string functions in object-oriented style. -For instance, string.byte(s, i) -can be written as s:byte(i). - - -

-The string library assumes one-byte character encodings. - - -

-

string.byte (s [, i [, j]])

-Returns the internal numerical codes of the characters s[i], -s[i+1], ···, s[j]. -The default value for i is 1; -the default value for j is i. - - -

-Note that numerical codes are not necessarily portable across platforms. - - - - -

-

string.char (···)

-Receives zero or more integers. -Returns a string with length equal to the number of arguments, -in which each character has the internal numerical code equal -to its corresponding argument. - - -

-Note that numerical codes are not necessarily portable across platforms. - - - - -

-

string.dump (function)

- - -

-Returns a string containing a binary representation of the given function, -so that a later loadstring on this string returns -a copy of the function. -function must be a Lua function without upvalues. - - - - -

-

string.find (s, pattern [, init [, plain]])

-Looks for the first match of -pattern in the string s. -If it finds a match, then find returns the indices of s -where this occurrence starts and ends; -otherwise, it returns nil. -A third, optional numerical argument init specifies -where to start the search; -its default value is 1 and can be negative. -A value of true as a fourth, optional argument plain -turns off the pattern matching facilities, -so the function does a plain "find substring" operation, -with no characters in pattern being considered "magic". -Note that if plain is given, then init must be given as well. - - -

-If the pattern has captures, -then in a successful match -the captured values are also returned, -after the two indices. - - - - -

-

string.format (formatstring, ···)

-Returns a formatted version of its variable number of arguments -following the description given in its first argument (which must be a string). -The format string follows the same rules as the printf family of -standard C functions. -The only differences are that the options/modifiers -*, l, L, n, p, -and h are not supported -and that there is an extra option, q. -The q option formats a string in a form suitable to be safely read -back by the Lua interpreter: -the string is written between double quotes, -and all double quotes, newlines, embedded zeros, -and backslashes in the string -are correctly escaped when written. -For instance, the call - -
-     string.format('%q', 'a string with "quotes" and \n new line')
-

-will produce the string: - -

-     "a string with \"quotes\" and \
-      new line"
-
- -

-The options c, d, E, e, f, -g, G, i, o, u, X, and x all -expect a number as argument, -whereas q and s expect a string. - - -

-This function does not accept string values -containing embedded zeros, -except as arguments to the q option. - - - - -

-

string.gmatch (s, pattern)

-Returns an iterator function that, -each time it is called, -returns the next captures from pattern over string s. -If pattern specifies no captures, -then the whole match is produced in each call. - - -

-As an example, the following loop - -

-     s = "hello world from Lua"
-     for w in string.gmatch(s, "%a+") do
-       print(w)
-     end
-

-will iterate over all the words from string s, -printing one per line. -The next example collects all pairs key=value from the -given string into a table: - -

-     t = {}
-     s = "from=world, to=Lua"
-     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
-       t[k] = v
-     end
-
- -

-For this function, a '^' at the start of a pattern does not -work as an anchor, as this would prevent the iteration. - - - - -

-

string.gsub (s, pattern, repl [, n])

-Returns a copy of s -in which all (or the first n, if given) -occurrences of the pattern have been -replaced by a replacement string specified by repl, -which can be a string, a table, or a function. -gsub also returns, as its second value, -the total number of matches that occurred. - - -

-If repl is a string, then its value is used for replacement. -The character % works as an escape character: -any sequence in repl of the form %n, -with n between 1 and 9, -stands for the value of the n-th captured substring (see below). -The sequence %0 stands for the whole match. -The sequence %% stands for a single %. - - -

-If repl is a table, then the table is queried for every match, -using the first capture as the key; -if the pattern specifies no captures, -then the whole match is used as the key. - - -

-If repl is a function, then this function is called every time a -match occurs, with all captured substrings passed as arguments, -in order; -if the pattern specifies no captures, -then the whole match is passed as a sole argument. - - -

-If the value returned by the table query or by the function call -is a string or a number, -then it is used as the replacement string; -otherwise, if it is false or nil, -then there is no replacement -(that is, the original match is kept in the string). - - -

-Here are some examples: - -

-     x = string.gsub("hello world", "(%w+)", "%1 %1")
-     --> x="hello hello world world"
-     
-     x = string.gsub("hello world", "%w+", "%0 %0", 1)
-     --> x="hello hello world"
-     
-     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
-     --> x="world hello Lua from"
-     
-     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
-     --> x="home = /home/roberto, user = roberto"
-     
-     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
-           return loadstring(s)()
-         end)
-     --> x="4+5 = 9"
-     
-     local t = {name="lua", version="5.1"}
-     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
-     --> x="lua-5.1.tar.gz"
-
- - - -

-

string.len (s)

-Receives a string and returns its length. -The empty string "" has length 0. -Embedded zeros are counted, -so "a\000bc\000" has length 5. - - - - -

-

string.lower (s)

-Receives a string and returns a copy of this string with all -uppercase letters changed to lowercase. -All other characters are left unchanged. -The definition of what an uppercase letter is depends on the current locale. - - - - -

-

string.match (s, pattern [, init])

-Looks for the first match of -pattern in the string s. -If it finds one, then match returns -the captures from the pattern; -otherwise it returns nil. -If pattern specifies no captures, -then the whole match is returned. -A third, optional numerical argument init specifies -where to start the search; -its default value is 1 and can be negative. - - - - -

-

string.rep (s, n)

-Returns a string that is the concatenation of n copies of -the string s. - - - - -

-

string.reverse (s)

-Returns a string that is the string s reversed. - - - - -

-

string.sub (s, i [, j])

-Returns the substring of s that -starts at i and continues until j; -i and j can be negative. -If j is absent, then it is assumed to be equal to -1 -(which is the same as the string length). -In particular, -the call string.sub(s,1,j) returns a prefix of s -with length j, -and string.sub(s, -i) returns a suffix of s -with length i. - - - - -

-

string.upper (s)

-Receives a string and returns a copy of this string with all -lowercase letters changed to uppercase. -All other characters are left unchanged. -The definition of what a lowercase letter is depends on the current locale. - - - -

5.4.1 - Patterns

- - -

Character Class:

-A character class is used to represent a set of characters. -The following combinations are allowed in describing a character class: - -

    - -
  • x: -(where x is not one of the magic characters -^$()%.[]*+-?) -represents the character x itself. -
    • - -
  • .: (a dot) represents all characters.
    • - -
  • %a: represents all letters.
    • - -
  • %c: represents all control characters.
    • - -
  • %d: represents all digits.
    • - -
  • %l: represents all lowercase letters.
    • - -
  • %p: represents all punctuation characters.
    • - -
  • %s: represents all space characters.
    • - -
  • %u: represents all uppercase letters.
    • - -
  • %w: represents all alphanumeric characters.
    • - -
  • %x: represents all hexadecimal digits.
    • - -
  • %z: represents the character with representation 0.
    • - -
  • %x: (where x is any non-alphanumeric character) -represents the character x. -This is the standard way to escape the magic characters. -Any punctuation character (even the non magic) -can be preceded by a '%' -when used to represent itself in a pattern. -
    • - -
  • [set]: -represents the class which is the union of all -characters in set. -A range of characters can be specified by -separating the end characters of the range with a '-'. -All classes %x described above can also be used as -components in set. -All other characters in set represent themselves. -For example, [%w_] (or [_%w]) -represents all alphanumeric characters plus the underscore, -[0-7] represents the octal digits, -and [0-7%l%-] represents the octal digits plus -the lowercase letters plus the '-' character. - - -

    -The interaction between ranges and classes is not defined. -Therefore, patterns like [%a-z] or [a-%%] -have no meaning. -

    • - -
  • [^set]: -represents the complement of set, -where set is interpreted as above. -
    • - -

-For all classes represented by single letters (%a, %c, etc.), -the corresponding uppercase letter represents the complement of the class. -For instance, %S represents all non-space characters. - - -

-The definitions of letter, space, and other character groups -depend on the current locale. -In particular, the class [a-z] may not be equivalent to %l. - - - - - -

Pattern Item:

-A pattern item can be - -

    - -
  • -a single character class, -which matches any single character in the class; -
    • - -
  • -a single character class followed by '*', -which matches 0 or more repetitions of characters in the class. -These repetition items will always match the longest possible sequence; -
    • - -
  • -a single character class followed by '+', -which matches 1 or more repetitions of characters in the class. -These repetition items will always match the longest possible sequence; -
    • - -
  • -a single character class followed by '-', -which also matches 0 or more repetitions of characters in the class. -Unlike '*', -these repetition items will always match the shortest possible sequence; -
    • - -
  • -a single character class followed by '?', -which matches 0 or 1 occurrence of a character in the class; -
    • - -
  • -%n, for n between 1 and 9; -such item matches a substring equal to the n-th captured string -(see below); -
    • - -
  • -%bxy, where x and y are two distinct characters; -such item matches strings that start with x, end with y, -and where the x and y are balanced. -This means that, if one reads the string from left to right, -counting +1 for an x and -1 for a y, -the ending y is the first y where the count reaches 0. -For instance, the item %b() matches expressions with -balanced parentheses. -
    • - -
- - - - -

Pattern:

-A pattern is a sequence of pattern items. -A '^' at the beginning of a pattern anchors the match at the -beginning of the subject string. -A '$' at the end of a pattern anchors the match at the -end of the subject string. -At other positions, -'^' and '$' have no special meaning and represent themselves. - - - - - -

Captures:

-A pattern can contain sub-patterns enclosed in parentheses; -they describe captures. -When a match succeeds, the substrings of the subject string -that match captures are stored (captured) for future use. -Captures are numbered according to their left parentheses. -For instance, in the pattern "(a*(.)%w(%s*))", -the part of the string matching "a*(.)%w(%s*)" is -stored as the first capture (and therefore has number 1); -the character matching "." is captured with number 2, -and the part matching "%s*" has number 3. - - -

-As a special case, the empty capture () captures -the current string position (a number). -For instance, if we apply the pattern "()aa()" on the -string "flaaap", there will be two captures: 3 and 5. - - -

-A pattern cannot contain embedded zeros. Use %z instead. - - - - - - - - - - - -

5.5 - Table Manipulation

-This library provides generic functions for table manipulation. -It provides all its functions inside the table table. - - -

-Most functions in the table library assume that the table -represents an array or a list. -For these functions, when we talk about the "length" of a table -we mean the result of the length operator. - - -

-

table.concat (table [, sep [, i [, j]]])

-Given an array where all elements are strings or numbers, -returns table[i]..sep..table[i+1] ··· sep..table[j]. -The default value for sep is the empty string, -the default for i is 1, -and the default for j is the length of the table. -If i is greater than j, returns the empty string. - - - - -

-

table.insert (table, [pos,] value)

- - -

-Inserts element value at position pos in table, -shifting up other elements to open space, if necessary. -The default value for pos is n+1, -where n is the length of the table (see §2.5.5), -so that a call table.insert(t,x) inserts x at the end -of table t. - - - - -

-

table.maxn (table)

- - -

-Returns the largest positive numerical index of the given table, -or zero if the table has no positive numerical indices. -(To do its job this function does a linear traversal of -the whole table.) - - - - -

-

table.remove (table [, pos])

- - -

-Removes from table the element at position pos, -shifting down other elements to close the space, if necessary. -Returns the value of the removed element. -The default value for pos is n, -where n is the length of the table, -so that a call table.remove(t) removes the last element -of table t. - - - - -

-

table.sort (table [, comp])

-Sorts table elements in a given order, in-place, -from table[1] to table[n], -where n is the length of the table. -If comp is given, -then it must be a function that receives two table elements, -and returns true -when the first is less than the second -(so that not comp(a[i+1],a[i]) will be true after the sort). -If comp is not given, -then the standard Lua operator < is used instead. - - -

-The sort algorithm is not stable; -that is, elements considered equal by the given order -may have their relative positions changed by the sort. - - - - - - - -

5.7 - Input and Output Facilities

- -

-The I/O library provides two different styles for file manipulation. -The first one uses implicit file descriptors; -that is, there are operations to set a default input file and a -default output file, -and all input/output operations are over these default files. -The second style uses explicit file descriptors. - - -

-When using implicit file descriptors, -all operations are supplied by table io. -When using explicit file descriptors, -the operation io.open returns a file descriptor -and then all operations are supplied as methods of the file descriptor. - - -

-The table io also provides -three predefined file descriptors with their usual meanings from C: -io.stdin, io.stdout, and io.stderr. -The I/O library never closes these files. - - -

-Unless otherwise stated, -all I/O functions return nil on failure -(plus an error message as a second result and -a system-dependent error code as a third result) -and some value different from nil on success. - - -

-

io.close ([file])

- - -

-Equivalent to file:close(). -Without a file, closes the default output file. - - - - -

-

io.flush ()

- - -

-Equivalent to file:flush over the default output file. - - - - -

-

io.input ([file])

- - -

-When called with a file name, it opens the named file (in text mode), -and sets its handle as the default input file. -When called with a file handle, -it simply sets this file handle as the default input file. -When called without parameters, -it returns the current default input file. - - -

-In case of errors this function raises the error, -instead of returning an error code. - - - - -

-

io.lines ([filename])

- - -

-Opens the given file name in read mode -and returns an iterator function that, -each time it is called, -returns a new line from the file. -Therefore, the construction - -

-     for line in io.lines(filename) do body end
-

-will iterate over all lines of the file. -When the iterator function detects the end of file, -it returns nil (to finish the loop) and automatically closes the file. - - -

-The call io.lines() (with no file name) is equivalent -to io.input():lines(); -that is, it iterates over the lines of the default input file. -In this case it does not close the file when the loop ends. - - - - -

-

io.open (filename [, mode])

- - -

-This function opens a file, -in the mode specified in the string mode. -It returns a new file handle, -or, in case of errors, nil plus an error message. - - -

-The mode string can be any of the following: - -

    -
  • "r": read mode (the default);
    • -
  • "w": write mode;
    • -
  • "a": append mode;
    • -
  • "r+": update mode, all previous data is preserved;
    • -
  • "w+": update mode, all previous data is erased;
    • -
  • "a+": append update mode, previous data is preserved, - writing is only allowed at the end of file.
    • -

-The mode string can also have a 'b' at the end, -which is needed in some systems to open the file in binary mode. -This string is exactly what is used in the -standard C function fopen. - - - - -

-

io.output ([file])

- - -

-Similar to io.input, but operates over the default output file. - - - - -

-

io.popen (prog [, mode])

- - -

-Starts program prog in a separated process and returns -a file handle that you can use to read data from this program -(if mode is "r", the default) -or to write data to this program -(if mode is "w"). - - -

-This function is system dependent and is not available -on all platforms. - - - - -

-

io.read (···)

- - -

-Equivalent to io.input():read. - - - - -

-

io.tmpfile ()

- - -

-Returns a handle for a temporary file. -This file is opened in update mode -and it is automatically removed when the program ends. - - - - -

-

io.type (obj)

- - -

-Checks whether obj is a valid file handle. -Returns the string "file" if obj is an open file handle, -"closed file" if obj is a closed file handle, -or nil if obj is not a file handle. - - - - -

-

io.write (···)

- - -

-Equivalent to io.output():write. - - - - -

-

file:close ()

- - -

-Closes file. -Note that files are automatically closed when -their handles are garbage collected, -but that takes an unpredictable amount of time to happen. - - - - -

-

file:flush ()

- - -

-Saves any written data to file. - - - - -

-

file:lines ()

- - -

-Returns an iterator function that, -each time it is called, -returns a new line from the file. -Therefore, the construction - -

-     for line in file:lines() do body end
-

-will iterate over all lines of the file. -(Unlike io.lines, this function does not close the file -when the loop ends.) - - - - -

-

file:read (···)

- - -

-Reads the file file, -according to the given formats, which specify what to read. -For each format, -the function returns a string (or a number) with the characters read, -or nil if it cannot read data with the specified format. -When called without formats, -it uses a default format that reads the entire next line -(see below). - - -

-The available formats are - -

    - -
  • "*n": -reads a number; -this is the only format that returns a number instead of a string. -
    • - -
  • "*a": -reads the whole file, starting at the current position. -On end of file, it returns the empty string. -
    • - -
  • "*l": -reads the next line (skipping the end of line), -returning nil on end of file. -This is the default format. -
    • - -
  • number: -reads a string with up to this number of characters, -returning nil on end of file. -If number is zero, -it reads nothing and returns an empty string, -or nil on end of file. -
    • - -
- - - -

-

file:seek ([whence] [, offset])

- - -

-Sets and gets the file position, -measured from the beginning of the file, -to the position given by offset plus a base -specified by the string whence, as follows: - -

    -
  • "set": base is position 0 (beginning of the file);
    • -
  • "cur": base is current position;
    • -
  • "end": base is end of file;
    • -

-In case of success, function seek returns the final file position, -measured in bytes from the beginning of the file. -If this function fails, it returns nil, -plus a string describing the error. - - -

-The default value for whence is "cur", -and for offset is 0. -Therefore, the call file:seek() returns the current -file position, without changing it; -the call file:seek("set") sets the position to the -beginning of the file (and returns 0); -and the call file:seek("end") sets the position to the -end of the file, and returns its size. - - - - -

-

file:setvbuf (mode [, size])

- - -

-Sets the buffering mode for an output file. -There are three available modes: - -

    - -
  • "no": -no buffering; the result of any output operation appears immediately. -
    • - -
  • "full": -full buffering; output operation is performed only -when the buffer is full (or when you explicitly flush the file -(see io.flush)). -
    • - -
  • "line": -line buffering; output is buffered until a newline is output -or there is any input from some special files -(such as a terminal device). -
    • - -

-For the last two cases, size -specifies the size of the buffer, in bytes. -The default is an appropriate size. - - - - -

-

file:write (···)

- - -

-Writes the value of each of its arguments to -the file. -The arguments must be strings or numbers. -To write other values, -use tostring or string.format before write. - - - - - - - -

5.8 - Operating System Facilities

- -

-This library is implemented through table os. - - -

-

os.clock ()

- - -

-Returns an approximation of the amount in seconds of CPU time -used by the program. - - - - -

-

os.date ([format [, time]])

- - -

-Returns a string or a table containing date and time, -formatted according to the given string format. - - -

-If the time argument is present, -this is the time to be formatted -(see the os.time function for a description of this value). -Otherwise, date formats the current time. - - -

-If format starts with '!', -then the date is formatted in Coordinated Universal Time. -After this optional character, -if format is the string "*t", -then date returns a table with the following fields: -year (four digits), month (1--12), day (1--31), -hour (0--23), min (0--59), sec (0--61), -wday (weekday, Sunday is 1), -yday (day of the year), -and isdst (daylight saving flag, a boolean). - - -

-If format is not "*t", -then date returns the date as a string, -formatted according to the same rules as the C function strftime. - - -

-When called without arguments, -date returns a reasonable date and time representation that depends on -the host system and on the current locale -(that is, os.date() is equivalent to os.date("%c")). - - - - -

-

os.difftime (t2, t1)

- - -

-Returns the number of seconds from time t1 to time t2. -In POSIX, Windows, and some other systems, -this value is exactly t2-t1. - - - - -

-

os.execute ([command])

- - -

-This function is equivalent to the C function system. -It passes command to be executed by an operating system shell. -It returns a status code, which is system-dependent. -If command is absent, then it returns nonzero if a shell is available -and zero otherwise. - - - - -

-

os.exit ([code])

- - -

-Calls the C function exit, -with an optional code, -to terminate the host program. -The default value for code is the success code. - - - - -

-

os.getenv (varname)

- - -

-Returns the value of the process environment variable varname, -or nil if the variable is not defined. - - - - -

-

os.remove (filename)

- - -

-Deletes the file or directory with the given name. -Directories must be empty to be removed. -If this function fails, it returns nil, -plus a string describing the error. - - - - -

-

os.rename (oldname, newname)

- - -

-Renames file or directory named oldname to newname. -If this function fails, it returns nil, -plus a string describing the error. - - - - -

-

os.setlocale (locale [, category])

- - -

-Sets the current locale of the program. -locale is a string specifying a locale; -category is an optional string describing which category to change: -"all", "collate", "ctype", -"monetary", "numeric", or "time"; -the default category is "all". -The function returns the name of the new locale, -or nil if the request cannot be honored. - - -

-If locale is the empty string, -the current locale is set to an implementation-defined native locale. -If locale is the string "C", -the current locale is set to the standard C locale. - - -

-When called with nil as the first argument, -this function only returns the name of the current locale -for the given category. - - - - -

-

os.time ([table])

- - -

-Returns the current time when called without arguments, -or a time representing the date and time specified by the given table. -This table must have fields year, month, and day, -and may have fields hour, min, sec, and isdst -(for a description of these fields, see the os.date function). - - -

-The returned value is a number, whose meaning depends on your system. -In POSIX, Windows, and some other systems, this number counts the number -of seconds since some given start time (the "epoch"). -In other systems, the meaning is not specified, -and the number returned by time can be used only as an argument to -date and difftime. - - - - -

-

os.tmpname ()

- - -

-Returns a string with a file name that can -be used for a temporary file. -The file must be explicitly opened before its use -and explicitly removed when no longer needed. - - -

-On some systems (POSIX), -this function also creates a file with that name, -to avoid security risks. -(Someone else might create the file with wrong permissions -in the time between getting the name and creating the file.) -You still have to open the file to use it -and to remove it (even if you do not use it). - - -

-When possible, -you may prefer to use io.tmpfile, -which automatically removes the file when the program ends. - - - - - - - -

5.9 - The Debug Library

- -

-This library provides -the functionality of the debug interface to Lua programs. -You should exert care when using this library. -The functions provided here should be used exclusively for debugging -and similar tasks, such as profiling. -Please resist the temptation to use them as a -usual programming tool: -they can be very slow. -Moreover, several of these functions -violate some assumptions about Lua code -(e.g., that variables local to a function -cannot be accessed from outside or -that userdata metatables cannot be changed by Lua code) -and therefore can compromise otherwise secure code. - - -

-All functions in this library are provided -inside the debug table. -All functions that operate over a thread -have an optional first argument which is the -thread to operate over. -The default is always the current thread. - - -

-

debug.debug ()

- - -

-Enters an interactive mode with the user, -running each string that the user enters. -Using simple commands and other debug facilities, -the user can inspect global and local variables, -change their values, evaluate expressions, and so on. -A line containing only the word cont finishes this function, -so that the caller continues its execution. - - -

-Note that commands for debug.debug are not lexically nested -within any function, and so have no direct access to local variables. - - - - -

-

debug.getfenv (o)

-Returns the environment of object o. - - - - -

-

debug.gethook ([thread])

- - -

-Returns the current hook settings of the thread, as three values: -the current hook function, the current hook mask, -and the current hook count -(as set by the debug.sethook function). - - - - -

-

debug.getinfo ([thread,] function [, what])

- - -

-Returns a table with information about a function. -You can give the function directly, -or you can give a number as the value of function, -which means the function running at level function of the call stack -of the given thread: -level 0 is the current function (getinfo itself); -level 1 is the function that called getinfo; -and so on. -If function is a number larger than the number of active functions, -then getinfo returns nil. - - -

-The returned table can contain all the fields returned by lua_getinfo, -with the string what describing which fields to fill in. -The default for what is to get all information available, -except the table of valid lines. -If present, -the option 'f' -adds a field named func with the function itself. -If present, -the option 'L' -adds a field named activelines with the table of -valid lines. - - -

-For instance, the expression debug.getinfo(1,"n").name returns -a table with a name for the current function, -if a reasonable name can be found, -and the expression debug.getinfo(print) -returns a table with all available information -about the print function. - - - - -

-

debug.getlocal ([thread,] level, local)

- - -

-This function returns the name and the value of the local variable -with index local of the function at level level of the stack. -(The first parameter or local variable has index 1, and so on, -until the last active local variable.) -The function returns nil if there is no local -variable with the given index, -and raises an error when called with a level out of range. -(You can call debug.getinfo to check whether the level is valid.) - - -

-Variable names starting with '(' (open parentheses) -represent internal variables -(loop control variables, temporaries, and C function locals). - - - - -

-

debug.getmetatable (object)

- - -

-Returns the metatable of the given object -or nil if it does not have a metatable. - - - - -

-

debug.getregistry ()

- - -

-Returns the registry table (see §3.5). - - - - -

-

debug.getupvalue (func, up)

- - -

-This function returns the name and the value of the upvalue -with index up of the function func. -The function returns nil if there is no upvalue with the given index. - - - - -

-

debug.setfenv (object, table)

- - -

-Sets the environment of the given object to the given table. -Returns object. - - - - -

-

debug.sethook ([thread,] hook, mask [, count])

- - -

-Sets the given function as a hook. -The string mask and the number count describe -when the hook will be called. -The string mask may have the following characters, -with the given meaning: - -

    -
  • "c": the hook is called every time Lua calls a function;
    • -
  • "r": the hook is called every time Lua returns from a function;
    • -
  • "l": the hook is called every time Lua enters a new line of code.
    • -

-With a count different from zero, -the hook is called after every count instructions. - - -

-When called without arguments, -debug.sethook turns off the hook. - - -

-When the hook is called, its first parameter is a string -describing the event that has triggered its call: -"call", "return" (or "tail return", -when simulating a return from a tail call), -"line", and "count". -For line events, -the hook also gets the new line number as its second parameter. -Inside a hook, -you can call getinfo with level 2 to get more information about -the running function -(level 0 is the getinfo function, -and level 1 is the hook function), -unless the event is "tail return". -In this case, Lua is only simulating the return, -and a call to getinfo will return invalid data. - - - - -

-

debug.setlocal ([thread,] level, local, value)

- - -

-This function assigns the value value to the local variable -with index local of the function at level level of the stack. -The function returns nil if there is no local -variable with the given index, -and raises an error when called with a level out of range. -(You can call getinfo to check whether the level is valid.) -Otherwise, it returns the name of the local variable. - - - - -

-

debug.setmetatable (object, table)

- - -

-Sets the metatable for the given object to the given table -(which can be nil). - - - - -

-

debug.setupvalue (func, up, value)

- - -

-This function assigns the value value to the upvalue -with index up of the function func. -The function returns nil if there is no upvalue -with the given index. -Otherwise, it returns the name of the upvalue. - - - - -

-

debug.traceback ([thread,] [message [, level]])

- - -

-Returns a string with a traceback of the call stack. -An optional message string is appended -at the beginning of the traceback. -An optional level number tells at which level -to start the traceback -(default is 1, the function calling traceback). - - - - - - - -

6 - Lua Stand-alone

- -

-Although Lua has been designed as an extension language, -to be embedded in a host C program, -it is also frequently used as a stand-alone language. -An interpreter for Lua as a stand-alone language, -called simply lua, -is provided with the standard distribution. -The stand-alone interpreter includes -all standard libraries, including the debug library. -Its usage is: - -

-     lua [options] [script [args]]
-

-The options are: - -

    -
  • -e stat: executes string stat;
    • -
  • -l mod: "requires" mod;
    • -
  • -i: enters interactive mode after running script;
    • -
  • -v: prints version information;
    • -
  • --: stops handling options;
    • -
  • -: executes stdin as a file and stops handling options.
    • -

-After handling its options, lua runs the given script, -passing to it the given args as string arguments. -When called without arguments, -lua behaves as lua -v -i -when the standard input (stdin) is a terminal, -and as lua - otherwise. - - -

-Before running any argument, -the interpreter checks for an environment variable LUA_INIT. -If its format is @filename, -then lua executes the file. -Otherwise, lua executes the string itself. - - -

-All options are handled in order, except -i. -For instance, an invocation like - -

-     $ lua -e'a=1' -e 'print(a)' script.lua
-

-will first set a to 1, then print the value of a (which is '1'), -and finally run the file script.lua with no arguments. -(Here $ is the shell prompt. Your prompt may be different.) - - -

-Before starting to run the script, -lua collects all arguments in the command line -in a global table called arg. -The script name is stored at index 0, -the first argument after the script name goes to index 1, -and so on. -Any arguments before the script name -(that is, the interpreter name plus the options) -go to negative indices. -For instance, in the call - -

-     $ lua -la b.lua t1 t2
-

-the interpreter first runs the file a.lua, -then creates a table - -

-     arg = { [-2] = "lua", [-1] = "-la",
-             [0] = "b.lua",
-             [1] = "t1", [2] = "t2" }
-

-and finally runs the file b.lua. -The script is called with arg[1], arg[2], ··· -as arguments; -it can also access these arguments with the vararg expression '...'. - - -

-In interactive mode, -if you write an incomplete statement, -the interpreter waits for its completion -by issuing a different prompt. - - -

-If the global variable _PROMPT contains a string, -then its value is used as the prompt. -Similarly, if the global variable _PROMPT2 contains a string, -its value is used as the secondary prompt -(issued during incomplete statements). -Therefore, both prompts can be changed directly on the command line -or in any Lua programs by assigning to _PROMPT. -See the next example: - -

-     $ lua -e"_PROMPT='myprompt> '" -i
-

-(The outer pair of quotes is for the shell, -the inner pair is for Lua.) -Note the use of -i to enter interactive mode; -otherwise, -the program would just end silently -right after the assignment to _PROMPT. - - -

-To allow the use of Lua as a -script interpreter in Unix systems, -the stand-alone interpreter skips -the first line of a chunk if it starts with #. -Therefore, Lua scripts can be made into executable programs -by using chmod +x and the #! form, -as in - -

-     #!/usr/local/bin/lua
-

-(Of course, -the location of the Lua interpreter may be different in your machine. -If lua is in your PATH, -then - -

-     #!/usr/bin/env lua
-

-is a more portable solution.) - - - -

7 - Incompatibilities with the Previous Version

- -

-Here we list the incompatibilities that you may find when moving a program -from Lua 5.0 to Lua 5.1. -You can avoid most of the incompatibilities compiling Lua with -appropriate options (see file luaconf.h). -However, -all these compatibility options will be removed in the next version of Lua. - - - -

7.1 - Changes in the Language

-
    - -
  • -The vararg system changed from the pseudo-argument arg with a -table with the extra arguments to the vararg expression. -(See compile-time option LUA_COMPAT_VARARG in luaconf.h.) -
    • - -
  • -There was a subtle change in the scope of the implicit -variables of the for statement and for the repeat statement. -
    • - -
  • -The long string/long comment syntax ([[string]]) -does not allow nesting. -You can use the new syntax ([=[string]=]) in these cases. -(See compile-time option LUA_COMPAT_LSTR in luaconf.h.) -
    • - -
- - - - -

7.2 - Changes in the Libraries

-
    - -
  • -Function string.gfind was renamed string.gmatch. -(See compile-time option LUA_COMPAT_GFIND in luaconf.h.) -
    • - -
  • -When string.gsub is called with a function as its -third argument, -whenever this function returns nil or false the -replacement string is the whole match, -instead of the empty string. -
    • - -
  • -Function table.setn was deprecated. -Function table.getn corresponds -to the new length operator (#); -use the operator instead of the function. -(See compile-time option LUA_COMPAT_GETN in luaconf.h.) -
    • - -
  • -Function loadlib was renamed package.loadlib. -(See compile-time option LUA_COMPAT_LOADLIB in luaconf.h.) -
    • - -
  • -Function math.mod was renamed math.fmod. -(See compile-time option LUA_COMPAT_MOD in luaconf.h.) -
    • - -
  • -Functions table.foreach and table.foreachi are deprecated. -You can use a for loop with pairs or ipairs instead. -
    • - -
  • -There were substantial changes in function require due to -the new module system. -However, the new behavior is mostly compatible with the old, -but require gets the path from package.path instead -of from LUA_PATH. -
    • - -
  • -Function collectgarbage has different arguments. -Function gcinfo is deprecated; -use collectgarbage("count") instead. -
    • - -
- - - - -

7.3 - Changes in the API

-
    - -
  • -The luaopen_* functions (to open libraries) -cannot be called directly, -like a regular C function. -They must be called through Lua, -like a Lua function. -
    • - -
  • -Function lua_open was replaced by lua_newstate to -allow the user to set a memory-allocation function. -You can use luaL_newstate from the standard library to -create a state with a standard allocation function -(based on realloc). -
    • - -
  • -Functions luaL_getn and luaL_setn -(from the auxiliary library) are deprecated. -Use lua_objlen instead of luaL_getn -and nothing instead of luaL_setn. -
    • - -
  • -Function luaL_openlib was replaced by luaL_register. -
    • - -
  • -Function luaL_checkudata now throws an error when the given value -is not a userdata of the expected type. -(In Lua 5.0 it returned NULL.) -
    • - -
- - - - -

You may want to configure the replication backlog size (see the next -# sections of this file) with a sensible value depending on your needs. -# 3) Replication is automatic and does not need user intervention. After a -# network partition slaves automatically try to reconnect to masters -# and resynchronize with them. -# -# slaveof - -# If the master is password protected (using the "requirepass" configuration -# directive below) it is possible to tell the slave to authenticate before -# starting the replication synchronization process, otherwise the master will -# refuse the slave request. -# -# masterauth - -# When a slave loses its connection with the master, or when the replication -# is still in progress, the slave can act in two different ways: -# -# 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will -# still reply to client requests, possibly with out of date data, or the -# data set may just be empty if this is the first synchronization. -# -# 2) if slave-serve-stale-data is set to 'no' the slave will reply with -# an error "SYNC with master in progress" to all the kind of commands -# but to INFO and SLAVEOF. -# -slave-serve-stale-data yes - -# You can configure a slave instance to accept writes or not. Writing against -# a slave instance may be useful to store some ephemeral data (because data -# written on a slave will be easily deleted after resync with the master) but -# may also cause problems if clients are writing to it because of a -# misconfiguration. -# -# Since Redis 2.6 by default slaves are read-only. -# -# Note: read only slaves are not designed to be exposed to untrusted clients -# on the internet. It's just a protection layer against misuse of the instance. -# Still a read only slave exports by default all the administrative commands -# such as CONFIG, DEBUG, and so forth. To a limited extent you can improve -# security of read only slaves using 'rename-command' to shadow all the -# administrative / dangerous commands. -slave-read-only yes - -# Replication SYNC strategy: disk or socket. -# -# ------------------------------------------------------- -# WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY -# ------------------------------------------------------- -# -# New slaves and reconnecting slaves that are not able to continue the replication -# process just receiving differences, need to do what is called a "full -# synchronization". An RDB file is transmitted from the master to the slaves. -# The transmission can happen in two different ways: -# -# 1) Disk-backed: The Redis master creates a new process that writes the RDB -# file on disk. Later the file is transferred by the parent -# process to the slaves incrementally. -# 2) Diskless: The Redis master creates a new process that directly writes the -# RDB file to slave sockets, without touching the disk at all. -# -# With disk-backed replication, while the RDB file is generated, more slaves -# can be queued and served with the RDB file as soon as the current child producing -# the RDB file finishes its work. With diskless replication instead once -# the transfer starts, new slaves arriving will be queued and a new transfer -# will start when the current one terminates. -# -# When diskless replication is used, the master waits a configurable amount of -# time (in seconds) before starting the transfer in the hope that multiple slaves -# will arrive and the transfer can be parallelized. -# -# With slow disks and fast (large bandwidth) networks, diskless replication -# works better. -repl-diskless-sync no - -# When diskless replication is enabled, it is possible to configure the delay -# the server waits in order to spawn the child that transfers the RDB via socket -# to the slaves. -# -# This is important since once the transfer starts, it is not possible to serve -# new slaves arriving, that will be queued for the next RDB transfer, so the server -# waits a delay in order to let more slaves arrive. -# -# The delay is specified in seconds, and by default is 5 seconds.

This can be the last ping or command received (if the master -# is still in the "connected" state), or the time that elapsed since the -# disconnection with the master (if the replication link is currently down). -# If the last interaction is too old, the slave will not try to failover -# at all. -# -# The point "2" can be tuned by user. Specifically a slave will not perform -# the failover if, since the last interaction with the master, the time -# elapsed is greater than: -# -# (node-timeout * slave-validity-factor) + repl-ping-slave-period -# -# So for example if node-timeout is 30 seconds, and the slave-validity-factor -# is 10, and assuming a default repl-ping-slave-period of 10 seconds, the -# slave will not try to failover if it was not able to talk with the master -# for longer than 310 seconds. -# -# A large slave-validity-factor may allow slaves with too old data to failover -# a master, while a too small value may prevent the cluster from being able to -# elect a slave at all. -# -# For maximum availability, it is possible to set the slave-validity-factor -# to a value of 0, which means, that slaves will always try to failover the -# master regardless of the last time they interacted with the master. -# (However they'll always try to apply a delay proportional to their -# offset rank). -# -# Zero is the only value able to guarantee that when all the partitions heal -# the cluster will always be able to continue. -# -# cluster-slave-validity-factor 10 - -# Cluster slaves are able to migrate to orphaned masters, that are masters -# that are left without working slaves.
