| E2fsprogs 1.19 (July 13, 2000) |
| ============================== |
| |
| Release the resize2fs program since the timeout before it could |
| be released under the GPL has finally expired. |
| |
| Add experimental support needed for the ext2 compression patches. |
| This requires compiling e2fsprogs with the --enable-compression flag |
| to the configure script. |
| |
| Added ext3 journalling support. E2fsck will run the journal (if |
| necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is |
| installed as a symlink to e2fsck. Fsck has been taught about ext3, |
| and treats it the same as ext2 in terms of the progress bar logic. |
| Dumpe2fs will display the superblock journalling information if the |
| filesystem has a journal. The ext2 library will now permit opening an |
| ext3 filesystem with the recovery flag set. This is necessary for |
| on-line dump's to work correctly, but there may be issues with this |
| working well since ext3 is much less aggressive about syncing blocks to |
| the filesystem, since they're safe on the journal. |
| |
| Tune2fs and e2fsck have been changed to allow the mount_count check to |
| be disabled by setting max_mount_count to -1. (This was already |
| supported by the kernel.) |
| |
| Create a symbolic link for fsck.ext3, since the e2fsprogs utilities |
| are used for ext3 as well. |
| |
| Added internationalization support for e2fsprogs; must be enabled |
| by passing --enable-nls to configure. |
| |
| Always use the provided ext2fs header files to insulate ourselves from |
| kernel version changes. Which include files are used by e2fsprogs |
| have also been cleaned up to improve portability. |
| |
| Limit the number of times that e2fsck updates the progress bar so that |
| people who are booting using a 9600 baud console don't get swamped by |
| too many updates. |
| |
| Improved the loop detection algorithm in e2sck's pass #3 so that it is |
| much, much faster for large filesystems with a large number of |
| directories. |
| |
| The memory footprint for e2fsck is now slightly smaller than before. |
| |
| E2fsck now checks if special devices have a non-zero size, and offers |
| to clear the size field if it finds such an inode. |
| |
| E2fsck now checks if special devices have the append-only flag set, |
| and offers to clear the inode. |
| |
| E2fsck now properly handles some "should never fail" cases during a |
| bitmap copy in pass5. |
| |
| E2fsck now properly prints control characters in filenames as ^A .. ^Z. |
| |
| E2fsck now calculates the correct location of the backup superblock in |
| the case of filesystem blocksizes > 1k. |
| |
| Fixed a bug in e2fsck's calculation of the number of inodes_per_block |
| which normally didn't cause problems under most filesystem parameters, |
| but could cause a valid superblock to be rejected in extreme cases. |
| Other checks for validating superblock values were made more |
| stringent. |
| |
| Added non-destructive write testing to the badblocks program, courtesy |
| of David Beattie. The badblocks also now has an option to input the |
| current set of bad blocks, so that known bad blocks are skipped to |
| speed up the badblocks test. There is also a persistent rescan |
| feature which causes badblocks to run until it has completed some |
| number of passes without discovering any new bad blocks. |
| |
| Badblocks now checks to see if the device is mounted and refuses to do |
| the tests involving writing to the device if it is mounted. Also, |
| badblocks now allows the number of blocks to be checked to be |
| defaulted to the size of the partition. |
| |
| Fixed a bug in fsck which didn't allow non-root users to be able to |
| check filesystems if there were any LABEL= or UUID= entries in |
| /etc/fstab. |
| |
| The Hurd doesn't support the filetype filesystem feature. The mke2fs |
| program now makes sure that for the Hurd, the filetype feature is |
| turned off. E2fsck will check to see if the filetype feature is |
| turned on for Hurd filesystems, and offer to turn off the feature. |
| |
| Mke2fs now has a safety check to make sure the number of blocks do not |
| exceed 32 bits even on a 64 bit platform. |
| |
| Really fixed a bug in fsck to allow "fsck -As" to run interactive |
| fsck's. (For those people who like to do interactive fsck's in the |
| /etc/rc scripts!?!) |
| |
| Debugfs has a few new features: the rdump command, which will do a |
| recursive dump of a directory and all of its contents, and the lcd |
| command which does a local chdir (much like the ftp command of the |
| same name). In addition, the debugfs program and the open_filesystem |
| command now takes three new options: -b and -s, which allows the |
| blocksize and superblock location to be specified, and the -c option |
| which is used in catastrophic situations where the block group |
| descriptors are corrupt. If the -c option is specified, debugfs will |
| skip trying to read in the block and inode bitmaps. |
| |
| Debugfs's lsdel command was fixed to handle bad blocks in the inode |
| table. |
| |
| A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use |
| 4 digit years. |
| |
| General improvements in error messages |
| |
| - Mke2fs prints a sane error message if the partition size is zero |
| (usually because the partition table wasn't reread by the |
| kernel due to the partition being busy), instead of "invalid |
| argument passed to ext2 library while initializing superblock". |
| |
| - Fsck now prints more self-explanatory message if an invalid UUID= |
| or LABEL= specification is passed to it. |
| |
| UUID library changed to use the LGPL. |
| |
| Fixed a bug in the UUID library where very rapid calls to the |
| time-based UUID generator could cause duplicate UUID's to be returned. |
| This was not a problem for e2fsprogs, but it could be a problem for |
| other users of the library. |
| |
| Make the UUID library more robust in the face of missing or an |
| improper /dev/urandom or /dev/random files. |
| |
| Added some random portability fixes for Solaris. |
| |
| Some minor man page updates. |
| |
| Fixed a memory leak in the ss library. |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| We now try to use lseek64 and open64 from the LFS if possible. |
| |
| The 3rd parameter in e2p's print_flags is now a flags word, instead of |
| a boolean option. |
| |
| The mark and unmark bitmap functions now return the previous state of |
| the bit that was being changed, which is useful for some speed |
| optimizations. |
| |
| The following functions have been added to enhance the badblocks list |
| handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and |
| ext2fs_badblocks_equal. |
| |
| The ext2 header files now have the latest journalling fields to the |
| superblock. |
| |
| The ext2fs_mkdir function in libext2fs now properly backs out of error |
| conditions robustly. |
| |
| Cleaned up makefiles: |
| - to cleanly compile with the -j flag. |
| - so distclean removes all generated files. |
| - so in case of an error while installing header files, the make aborts. |
| |
| Fix test_script so that it works correctly when compiling in the |
| source directory. |
| |
| The random UUID generation routine has been made slightly better in |
| the case where /dev/random doesn't exist. (Use of randomly-based UUID |
| is still not recommended if /dev/random doesn't exist, however; it's |
| better to use the time/ethernet MAC address UUID in this case.) |
| |
| Clean up the build process so it's more friendly in case of missing |
| directories. |
| |
| The ext2fs header file can now be #include'd into C++ programs. |
| |
| The e2p.h header file is now installed. |
| |
| Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. |
