| E2fsprogs 1.05 (September 7, 1996) |
| ================================== |
| |
| Add support for new fields in the ext2 superblock --- volume name, |
| volume UUID, and last mounted field. Dumpe2fs displays these fields, |
| tune2fs and mke2fs allows you to set them. E2fsck will automatically |
| generate a UUID for those volumes that don't have them. |
| |
| Put in support for e2fsck to recognize HURD specific ext2 features --- |
| most notably, the translator block. The e2fsprogs tools will now use |
| the creator_os field in the superblock to correctly handle different |
| OS-specific variants of the ext2 filesystem. |
| |
| E2fsck now fixes inodes which have a the deletion time set, but which |
| have a non-zero i_link_count field by offering to clear the deletion |
| time. Previously e2fsck assumed that the inode was deleted (per 0.3c |
| ext2 kernel behavior) and offered to unlink the file. |
| |
| If e2fsck sets the clean bit, but nothing else, set the exit code |
| FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it |
| set the filesystem valid bit when it was previously cleared. :-) This |
| was needed to make the HURD fsck driver happy. |
| |
| If the user refuses to attach an unattached inode, e2fsck will no |
| longer set the inode's link count. Otherwise, the inode would end up |
| getting marked as unused, which might cause loss of data later. |
| |
| Make the message issued by e2fsck when the superblock is corrupt less |
| confusing for users. It now mentions that another reason for the |
| "corrupt superblock" message might be that the partition might not be |
| an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) |
| |
| Make the libext2 library more robust so that e2fsck won't coredump on |
| an illegal superblock where the blocksize is zero. (f_crashdisk is |
| the test case). |
| |
| By default, create filesystems where the default checkinterval is 6 |
| months (180 days). Linux servers can be robust enough that 20 reboots |
| can be a long, long time. |
| |
| Added configure flag --enable-old-bitops, which forces the bitops to |
| use the old (native) bitmask operations. By default on the sparc |
| platform, the standard ext2 bit ordering is now used. |
| |
| Added a new feature to e2fsck to byte-swap filesystems; this can be |
| used to convert old m68k filesystems to use the standard byte-order |
| storage for the superblock, inodes, and directory blocks. This |
| function is invoked by using the '-s' option to e2fsck. |
| |
| Debugfs's "dump" command has been enhanced so that it writes out the |
| exact size of the file so that the nulls at the end of the file are |
| eliminated. The command also accept a new "-p" option which will |
| attempt to preserve the ownership, permissions, and file |
| modification/access times. |
| |
| Debugfs has two new options, -f and -R. The -R option allows the user |
| to execute a single debugfs command from the command line. The -f |
| option allows the user to specify a "command file" containing debugfs |
| commands which will get executed. |
| |
| Dumpe2fs now pretty prints the check interval, instead of just |
| printing the check interval as a number of seconds. |
| |
| Fix bugs in debugfs: the params command when no filesystem is opened |
| no longer causes a core dump. It is now possible to unlink a file |
| when a pathname containing a '/' is specified. |
| |
| Tune2fs has a new -C option which sets the number of times the |
| filesystem has been mounted. |
| |
| Fix the chattr '-v' option so that it actually works. Chattr was |
| being buggy about the -v option parsing. |
| |
| Programmers' notes: |
| ------------------- |
| |
| The directory lib/uuid contains a set of library routines to generate |
| DCE compatible UUIDs. |
| |
| Extended ext2fs_namei() to handle symbolic links. Added new function |
| ext2fs_nami_follow() which will follow last symbolic link in the case |
| where the pathname points to a sym link. |
| |
| The ext2fs_block_iterate function will now return the HURD translator |
| block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the |
| iterator to return data blocks only. The ext2fs.h file now defines |
| constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and |
| BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block |
| count field of the iterator callback function. |
| |
| The test script driver now takes an optional second argument, which is |
| the test case to be run. This allows you to run a test case without |
| needing to run the entire test suite. |
| |
| On Linux ELF systems, install the .so files in the correct places |
| (/usr/lib). The .so files must be stored in the same directory as the |
| .a files. |
| |
| Fixed miscellaneous HURD compilation issues with header file being |
| included in the right order. |
| |
| Fixed debugfs so that it resets optind to zero, not one, since setting |
| optind to zero is more correct. |
