Fixed a bug where if there was an + error reading from the disk, the number of bytes read + wasn't reliably set.

It handles all of the UUID + manipulation. + + * ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported + by the library.

(Thanks to Andreas Dilger + for pointing this out.) + +2001-01-11 + + * flushb.c (ext2fs_sync_device): New function which centralizes + all of the places which might try to use the BLKFLSBUF + or FDFLUSH ioctls (and usually failing to define them + since the system header files don't usually do this for + us, and we're trying to avoid usage of kernel include + files now). + +2001-01-10 + + * alloc.c, bb_inode.c, bitmaps.c, bitops.h, block.c, bmap.c, + bmove.c, brel.h, cmp_bitmaps.c, dblist.c, dblist_dir.c, + dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, fileio.c, + finddev.c, get_pathname.c, icount.c, inode.c, irel.h, + irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c, + mkjournal.c, namei.c, newdir.c, read_bb_file.c, test_io.c, + tst_iscan.c, unix_io.c, unlink.c: Change use of ino_t to + ext2_ino_t, to protect applications that attempt to + compile -D_FILE_OFFSET_BITS=64, since this inexplicably + changes ino_t(!?). So we use ext2_ino_t to avoid an + unexpected ABI change. + +2001-01-05 + + * dirblock.c (ext2fs_read_dir_block): Fix a potential case where + we may overrun allocated memory in case of a corrupted + filesystem (or an e2fsck test case :-) when byte-swapping + the directory block. + + * ext2fs.h: Indent the #warning to fix gcc -Wall complaint. + + * mkjournal.c (ext2fs_add_journal_device): Fix various gcc -Wall + complaints including a missing return 0 at the end of + ext2fs_add_journal_device. + +2001-01-03 + + * Makefile.in: Link in libe2p when creating libext2fs as a shared + library, since mkjournal.c now references fsetflags(). + + * mkjournal.c (ext2fs_add_journal_inode): Folded in Andreas + Dilger's changes (with fixups) to allow on-line creation + of a journal file. + + * ext2fs.h, closefs.c (ext2fs_flush): Add new flag, + EXT2_FLAG_SUPER_ONLY, which the close routines to only + update the superblock, and not the group descriptors. + +2000-12-30 Andreas Dilger + + * ismounted.c: add ext2fs_check_mount_point() function, which will + optionally return the mount point of a device if mounted + +2000-12-14 Andreas Dilger + + * mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive + ext2fs_add_journal_inode() + +2001-01-01 + + * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break + source (but not binary) compatibility of some users of the + ext2 library. They should just simply do a global search + and replace of struct ext2fs_sb with struct + ext2_super_block, and use their own private copy of + ext2_fs.h if they aren't already. + + * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c: + Replace use of ext2fs_sb with ext2_super_block. + +2000-12-31 + + * ext2fs.h: Cleaned up header file by removing definitions of + feature flags that might not have been defined in older + ext2 header files. Now that we're using our own + include/linux/ext2fs.h header file, this can never happen. + + * jfs_dat.h: Removed old header file which is no longer needed. + +2000-12-13 Theodore Ts'o + + * closefs.c (ext2fs_update_dynamic_rev): New function suggested + by Andreas Dilger to update the filesystem revision to + EXT2_DYNAMIC_REV. + + * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal + fields. + +2000-12-09 + + * ext2fs.h, mkjournal.c (ext2fs_add_journal_inode, + ext2fs_add_journal_device): Add a new argument to the APIs + of these function, which is a flags word. This is used to + allow the creation of a V1 superblock for those folks who + are using ext3 0.3b in production. Note, the user-land + interface for getting at this flag won't be documented, as + the V1 superblock is deprecated. + + * mkjournal.c (init_journal_superblock): Sync Stephen's changes + which creates a V2 superblock instead of a V1 superblock. + +2000-11-21 + + * test_io.c (test_write_blk, test_write_byte): Fix typos pointed + out by Andreas Dilger. + +2000-11-05 + + * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write}, + ext2_fs.h, Makefile.in: New file that has routines that + save ext2fs metadata to a file. + + * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned. + + * e2image.h: New file which defines the file format for the ext2 + image file. (Saved copy of ext2 metadata to a file as a + saving throw against worst-case damage.) + +2000-11-01 + + * inode.c (ext2fs_flush_icache): Add new function + ext2fs_flush_icache() which flushes the internal inode + cache. Applications which modify the inode table blocks + directly must call this function. + +2000-10-26 + + * mkjournal.c: Add #include of netinet/in.h, since Solaris + requires it for ntohl(). + + * ext2_io.h (io_channel_write_byte): Add new interface to allow + callers to write specific byte ranges.
