E2fsprogs 1.42.7 (January 1, 2013)
|
||||
==================================
|
||||
|
||||
Add some new options to filefrag from Lustre's patches to e2fsprogs:
|
||||
* add -k option to print extents in kB-sized units (like df -k)
|
||||
* add -b {blocksize} to print extents in blocksize units
|
||||
* add -e option to print extent format, even when FIBMAP is used
|
||||
* add -X option to print extents in hexadecimal format
|
||||
|
||||
Fix resize2fs so that it can handle off-line resizes of file systems
|
||||
with the flex_bg feature but without a resize_inode (or if we run out
|
||||
of reserved gdt blocks). This also fixes a problem where if the user
|
||||
creates a filesystem with a restricted number of reserved gdt blocks,
|
||||
an off-line resize which grows the file system could potentially
|
||||
result in file system corruption.
|
||||
|
||||
Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
|
||||
mke2fs crash due to a divide-by-zero if the 64bit file system feature
|
||||
is enabled.
|
||||
|
||||
Add to debugfs the functionality to corrupt a specific file system
|
||||
block via the "zap_block" command.
|
||||
|
||||
Add to debugfs the functionality to print out a hex dump of a block in
|
||||
the file system via the "block_dump" command.
|
||||
|
||||
Add to debugfs the functionality to manipulate the extent tree
|
||||
directly via the "extent_open" command.
|
||||
|
||||
Fix e2fsck so it can detect and fix inconsistencies in the interior
|
||||
nodes of an inode's extent tree.
|
||||
|
||||
Fix mke2fs's handling of the mmp_update_interval option. (Addresses
|
||||
Lustre Bug: LU-1888)
|
||||
|
||||
If e2fsprogs is compiled without --enable-quota, make sure that
|
||||
tune2fs can not turn on the feature for new-style quota support, since
|
||||
afterwards, none of the e2fsprogs tools will be willing to touch that
|
||||
file system.
|
||||
|
||||
Optimize e2fsck's so that it uses much less CPU for large file
|
||||
systems. This can result in significant speedups, especially on
|
||||
CPU-constrained systems. This was primarily done by optimizing
|
||||
libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
|
||||
|
||||
Fix debugfs's htree command so that all its messages are sent through
|
||||
the pager.
|
||||
|
||||
Fixed debugfs's "dump_file" and "cat" functions work correctly
|
||||
on file systems whose block size is greater than 8k.
|
||||
|
||||
Fix e2freefrag so it works on 64-bit file systems, and so it uses much
|
||||
less memory. (Addresses Google Bug: 7269948)
|
||||
|
||||
|
||||
Programmer's Notes
|
||||
------------------
|
||||
|
||||
Fix gcc -Wall nits.
|
||||
|
||||
Fix a spelling typo in the libext2fs texinfo documentation.
|
||||
|
||||
Change the output from "make check" so that tools such as emacs's "M-x
|
||||
compile" does not mistake the output as containing a compiler error.
|
||||
|
||||
Export two new functions from libext2fs: ext2fs_extent_node_split()
|
||||
and ext2fs_extent_goto2().
|
||||
|
||||
The ext2fs_extents_fix_parents() was fixed so it does not modify the
|
||||
location of the extent handle if its current location is at an
|
||||
interior node, rather than a leaf node of an inode's extent tree.
|
||||
|
||||
Add a regression test to assure that e2fsck can correctl fix an
|
||||
inconsistent interior node in an inode's extent tree.
|
||||
|
||||
Fixed the help text in the configure script for --enable-quota.
|
||||
|
||||
The m68k-specific bitops code has been removed since they were
|
||||
incorrectly treating bit numbers with the high bit set as signed
|
||||
integers. Furthermore, modern compilers do a good enough job
|
||||
optimizing the generic code there is no point in having the m68k
|
||||
specific asm statements.
|
||||
|
||||
Fixed how we link the test programs so they always use the static
|
||||
libraries, so that we test using the libraries which we have just
|
||||
built.
