E2fsprogs 1.15 (July 18, 1999)
|
|
==============================
|
|
|
|
Add configuration checks so that e2fsprogs will compile cleanly on
|
|
Linux 2.3 kernels that have renamed i_version to i_generation.
|
|
|
|
E2fsck now prints a progress/completion bar (and not just a simple
|
|
spinner) if the -C0 option is requested or if it receives a SIGUSR1
|
|
signal. Fsck will automatically manage the (potentially multiple)
|
|
e2fsck processes to print completion bars if it is given a -C option,
|
|
with the right thing happening if multiple filesystems are being
|
|
checked in parallel.
|
|
|
|
Mke2fs now has better automatic heuristics to determine the filesystem
|
|
parameters to be used for a particular filesystem. Added a new option
|
|
-T which allows the user to specify how the filesystem is to be used,
|
|
which helps mke2fs do a better job selecting the filesystem parameters.
|
|
|
|
Mke2fs now creates revision 1 filesystems by default, and with the
|
|
sparse superblock feature enabled. The sparse superblock feature is
|
|
not understood by Linux 2.0 kernels, so they will only allow read-only
|
|
mounts of filesystems with this sparse superblocks.
|
|
|
|
Fix bug where if /dev/null couldn't be opened (should never happen),
|
|
e2fsck would hang in a tight loop.
|
|
|
|
Make e2fsck handle the case where /lost+found isn't a directory.
|
|
|
|
E2fsck now uses mallinfo if it exists to get accurate statistics about
|
|
its memory usage.
|
|
|
|
Fix bug in e2fsck where it wouldn't check to see if a disconnected
|
|
inode had any problems before connecting it to /lost+found.
|
|
|
|
Add check to e2fsck so it makes sure that total number of inodes in
|
|
the filesystem is a sane number.
|
|
|
|
Fix fencepost error when clearing an the end of the block bitmap which
|
|
caused the last block in the bitmap not to get cleared.
|
|
|
|
Cleaned up a number of messages in e2fsck:
|
|
* The message "Group's #'s copy of the group descriptor..."
|
|
was fixed so that the correct number would be displayed.
|
|
* Added missing space in the "disk write-protected" error message
|
|
* Cleaned up the error message printed when a non-interactive
|
|
e2fsck needs to abort a check because the filesystem
|
|
appears to be mounted.
|
|
|
|
Added a new command-line utility, uuidgen, which will create and print
|
|
a UUID.
|
|
|
|
Make debugfs's icheck command more robust by checking to make sure an
|
|
inode has valid blocks before iterating over the inode's blocks.
|
|
|
|
UUID generation now uses a random-based scheme whenever possible to
|
|
prevent potential privacy problems.
|
|
|
|
Man pages for all of the UUID functions in the library were added.
|
|
|
|
Fixed bug in fsck so it won't coredump if a filesystem not in
|
|
/etc/fstab is given to it.
|
|
|
|
Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
|
|
that most of the other mount utilities understands.
|
|
|
|
Mke2fs will make a filesystem even if it appears mounted if the force
|
|
option is given.
|
|
|
|
Dumpe2fs has new command-line options which allow a filesystem expert
|
|
to specify the superblock and blocksize when opening a filesystem.
|
|
This is mainly useful when examining the remains of a toasted
|
|
filesystem.
|
|
|
|
The badblocks program has been updated to display correctly on disks
|
|
with large block numbers.
|
|
|
|
The badblocks program no longer gives spurious errors when errors
|
|
occur on non-block boundaries, which is common if the blocksize is
|
|
larger than 1k.
|
|
|
|
Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
|
|
MKE2FS_SYNC environment variable is set. This is to work around a VM
|
|
bug in the 2.0 kernel. I've heard a report that a RAID user was able
|
|
to trigger it even using a 2.2 kernel, but hopefully it will not be
|
|
needed for most Linux 2.2 users.
|
|
|
|
Fixed miscellaneous documentation and man pages.

Programmer's notes:
|
|
-------------------
|
|
|
|
Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
|
|
in e2fsck's pass1.c really should have been static.
|
|
|
|
The return value of the uuid_compare() function was changed to make it
|
|
match with the conventions used by strcmp, memcmp, and Paul Leach's
|
|
UUID sample document.
|
|
|
|
The "make depend" process has now been made more automated; it now
|
|
automatically word-wraps the dependencies, and only replaces source
|
|
Makefile.in if there has been a change in the dependencies. Also, a
|
|
top-level "make depend" now recurses through all the subdirectories
|
|
automatically.
|
|
|
|
The Makefile in .../util has been changed so that subst is built using
|
|
the native C compiler during a cross-compilation, since the subst
|
|
program is only used during the build process. Also add an explicit
|
|
rule to build util/subst by cd'ing to the correct directory and
|
|
running Makefile.
|
|
|
|
The man directories are defined in terms mandir, so that the configure
|
|
script can override the location of the manual pages.
|
|
|
|
The config files have been updated to recognize new machine types for
|
|
both the i386 and alpha families.
|
|
|
|
Fsck has been modified so that it will accurately create an
|
|
fsck_instance even when the noexecute flag is set. This allows for
|
|
accurate debugging of the fsck pass structure. Also, when the verbose
|
|
flag is given twice, fsck will print debugging information about when
|
|
fsck is waiting for jobs to finish.
