This was fixed +by seriously revamping the icount abstraction. Added a formal test +suite for the icount abstraction. + +Debugfs now has a "-l" option to the "ls" command, which lists the +inode number, permissions, owner, group, size, and name of the files +in the directory. + +Fix a bug in e2fsck where when a directory had its blocks moved to +another location during the pass 1b processing, the directory block +list wasn't updated, so pass 2 wouldn't check (and correct) the +correct directory block. + +E2fsck will now treat inodes which contain blocks which are claimed by +the filesystem metadata by treating them as multiply claimed blocks. +This way, the data in those blocks can be copied to a new block during +the pass 1b--1d processing. + +E2fsck will attempt to determine the correct superblock number and +display it in the diagnostic and warning messages if possible. + +Add support for a new (incompatible) feature, "sparse_super". This +feature reduces the number of blocks which contain copies of backup +superblocks and block group descriptors. (It is only an incompatible +feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now +support a new -s option; e2fsck will recognize filesystems built with +this feature turned on. + +E2fsck now checks the library to make sure is the correct version, +using new library functions. (This helps to diagnose incorrectly +installed e2fsprogs distributions.) + +Dumpe2fs now prints more information; its now prints the the +filesystem revision number, the filesystem sparse_super feature (if +present), the block ranges for each block group, and the offset from +the beginning of the block group. + +Mke2fs now distributes the inode and block bitmap blok so that the +won't be concentrated in one or two disks in RAID/striping setups. +Also, if the user chooses a 2k or 4k block group, mke2fs will try to +choose the largest blocks per group that be chosen. (For 2k blocks, +you can have up to 16384 blocks/group; for 4k blocks, you can have up +to 32768 blocks/group.) Previously mke2fs would not allow +specification of more than 8192 blocks per group, even if you were +using a 2k or 4k block group. + +Programmer's notes: +------------------- + +Added a new function ext2fs_create_icount2() which takes a "hint" +argument. This hint argument presets the icount array with the list +of inodes which actually need to be in the icount array. This really +helps to speed up e2fsck. + +Added a new function ext2fs_icount_validate() which checks the rep +invariant for the icount structure. This is used mostly for testing. + +The error message given when a bad inode number is passed to +test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of +EXT2FS_UNMARK_ERROR). + +Added a new function ext2fs_set_dir_block which sets the block of a +dblist entry, given the directory inode and blockcnt. + +Added a new function ext2fs_get_library_version() which returns the +current library version, and ext2fs_parse_version_string() which +returns a version number based on a e2fsprogs version string. + +The icount functions will return EINVAL if the passed in inode number +is out of bounds. + |
