The RELEASE-NOTES file was getting too big as be unweildy. It also made it hard to have simultaneous releases of older maintenance releases. So split it up into smaller files in the doc/RelNotes directory. Signed-off-by: Theodore Ts'o <tytso@mit.edu>

E2fsprogs 1.16 (October 22, 1999)
|
|
=================================
|
|
|
|
Fixed a race condition bug in fsck; when printing a progress bar, if
|
|
checking multiple filesystems in parallel, it was possible for fsck to
|
|
send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
|
|
handler, which would cause it to terminate with a signal 10.
|
|
|
|
E2fsck now properly handles filesystems that have the
|
|
INCOMPAT_FILETYPE feature turned on. It can be used to convert a
|
|
filesystem into using or not using FILETYPE feature.
|
|
|
|
E2fsck now properly handles filesystems that have the IMAGIC feature
|
|
turned on (this is used on Linux AFS servers).
|
|
|
|
The mke2fs program now creates filesystems that have the filetype and
|
|
sparse_superblock features enabled by default, unless it is run on a
|
|
pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
|
|
so there is now a new flag -O which allows the user to specify with
|
|
which features she would like to create the filesystem; "mke2fs -O
|
|
none" will create a filesystem compatible with 2.0 kernels.
|
|
|
|
The tune2fs program now has a -O option which allows the user to set
|
|
and reset "safe" filesystem features. Currently, the only ones which
|
|
allows to be modified are the filetype and sparse_superblock features.
|
|
Note setting or clearing either feature will require running e2fsck on
|
|
the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
|
|
requires that there is enough free space on the filesystem for the
|
|
extra superblocks which will be created by e2fsck.)
|
|
|
|
Debugfs can now set and print filesystem features in the superblock
|
|
using the "features" command. Dumpe2fs will print out the complete
|
|
set of features when listing the superblock.
|
|
|
|
Dumpe2fs has new options -f (force) and -h (header-only).
|
|
|
|
Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
|
|
message to come up. This could happen when decrementing or
|
|
incrementing a link count could result in an overflow.
|
|
|
|
Fixed a bug in e2fsck where the block count on the lost+found
|
|
directory would not be properly incremented when the directory was
|
|
expanded to the point where an indirect block needed to be allocated.
|
|
|
|
E2fsck now makes some additional sanity checks on the superblock to
|
|
avoid crashing or giving a memory allocation error if some of the
|
|
values in the superblock are unreasonable (but the superblock otherwise
|
|
looks valid).
|
|
|
|
Fixed a bug in e2fsck where a very badly corrupted filesystem might
|
|
require two passes to completely fix the filesystem. This happened if
|
|
an inode claimed blocks that was part of the filesystem metadata
|
|
(typically, when garbage was written into an inode table or indirect
|
|
block, since this kind of filesystem corruption normally doesn't
|
|
happen otherwise).
|
|
|
|
On the Alpha, glibc declares st_flags although it isn't actually used;
|
|
the configure script was improved to detect this case so that
|
|
e2fsprogs can avoid using the non-functional stat field.
|
|
|
|
The manual pages were updated to use a more consistent formatting
|
|
style consistent with standard Unix man pages. Mke2fs's man page
|
|
added documentation for a few previously undocumented options.
|
|
|
|
Fixed minor display bugs in tune2fs and mke2fs.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
|
|
|
|
Added features to parse and print feature strings into the e2p library.
|
|
(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
|
|
|
|
ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
|
|
whose directory entries contain proper filetype information if the
|
|
filesystem supports it.
|
|
|
|
ext2fs_link() now uses the low 3 bits of its flags parameter to pass
|
|
the directory entry filetype information. This is used to set the
|
|
directory entry filetype information if the filesystem supports it.
|
|
|
|
Fixed a bug in ext2fs_expand_dir() where the block count in a
|
|
directory's inode would not be properly incremented when the directory
|
|
was expanded to the point where an indirect block needed to be
|
|
allocated.
