Vitaliy Filippov 36c276358b Attempt to fix "head-of-line blocking" by LIST operations 2022-02-18 01:31:45 +03:00
Vitaliy Filippov df0cd85352 Fix another part of the "async sqe clear" bug (followup to d9857a5340) 2022-02-01 01:14:56 +03:00
Vitaliy Filippov d9857a5340 Check for SQEs, not for completions
Should finally fix Assertion `sqe != NULL' failed introduced after journaling
refactor in 0.6.11...

Vitaliy Filippov 7bdd92ca4f Fix build under clang and some warnings
Build problems fixed:
- void* pointer arithmetic which is a GNU extension (works as byte*)
- "variable size object may not be initialized" which is OK under GCC
- nullptr_t related error in json11 (it lacks 'operator <' in clang)

Warnings fixed:
- empty nested struct initializer { 0 } replaced by {}
- removed several unused lambda captures

Vitaliy Filippov f93491bc6c Implement journal write batching and slightly refactor journal writes
Slightly reduces WA. For example, in 4K T1Q128 replicated randwrite tests
WA is reduced from ~3.6 to ~3.1, in T1Q64 from ~3.8 to ~3.4.

Only effective without no_same_sector_overwrites.

Vitaliy Filippov 2a02f3c4c7 Add metadata superblock and check it on start
Refuse to start if the superblock is missing or bad version;
zero out the metadata area when initializing superblock.

Vitaliy Filippov ab39ce2bbb Use clean_entry_bitmap_size instead of entry_attr_size back because of changed bitmap handling 2021-04-10 17:44:12 +03:00

Vitaliy Filippov 307c1731c1 Forget all dirty_entries before stable big_write or delete during initialisation
This fixes a 'double_alloc' assertion in the following case:
- big_write object #1 v1 to block #100
- big_write object #1 v2 to block #101
- big_write object #2 v1 to block #100

Vitaliy Filippov b0ad1e1e6d Remember writes as "unsynced" only after completing them
Previously BS_OP_SYNC could take unfinished writes and add them into the journal before
they were actually completed. This was leading to crashes with the message
"BUG: Unexpected dirty_entry 2000000000001:9f2a0000 v3 unstable state during flush: 338"

Vitaliy Filippov 0d8b5e2ef9 Remove unused enqueue_op_first() 2021-03-08 17:04:10 +03:00
Vitaliy Filippov 98f1e2c277 Rework write/sync ordering
Make syncs wait for all previous writes because it's the only way
to make sure that OSDs do not receive incomplete writes in LIST results
during peering when some writes are still in progress.

Also simplify blockstore submission queue logic.
