Add a -c option to ncheck will verifies the file type information in the directory entry. Signed-off-by: "Theodore Ts'o"

libext2fs: display partial path if fs corrupted in ext2fs_get_pathname()

2012-01-17T20:38:31Z

The function ext2fs_get_pathname() used to return EXT2_ET_NO_DIRECTORY if one of the directories in an inode's pathname is not a directory. This is not very useful in an emergency, when the file system is corrupted. This commit will cause ext2fs_get_pathname() to return a partial pathname, which should help system administrators trying to use debugfs to investigate a corrupted file system.

debugfs: optimize ncheck and improve its error checking

2012-01-16T22:49:46Z

Don't call ext2fs_get_pathname() for every single directory; instead, only call it if we find a matching directory entry. In addition, if ext2fs_get_pathname() fails, print the number of the parent directory in angle parents so the user gets some additional information. Signed-off-by: "Theodore Ts'o"

libext2fs: change getpagesize to sysconf

2012-01-10T02:19:48Z

Newer versions of glibc no longer export the getpagesize() prototype when using recent versions of POSIX (_XOPEN_SOURCE). So building tdb.c gives use implicit function declaration warnings. Fix the issue by using the portable sysconf() function which returns the same answer. Signed-off-by: Mike Frysinger Signed-off-by: Theodore Ts'o

mke2fs: fix -T/-t usage output

2012-01-10T02:17:57Z

There is a slight desync between the mke2fs(8) man page and the mke2fs help output when it comes to the -t/-T options. Since the man page is correct, update the mke2fs usage string to match. Reported-by: Ben Kohler Signed-off-by: Mike Frysinger Signed-off-by: Theodore Ts'o

libext2fs: add bitmap statistics

2011-12-18T06:12:44Z

This feature is especially useful for better understanding how e2fsprogs tools (mainly e2fsck) treats bitmaps and what bitmap backend can be most suitable for particular bitmap. Backend itself (if implemented) can provide statistics of its own as well. [ Changed to provide basic statistics when enabled with the E2FSPROGS_BITMAPS_STATS environment variable -- tytso] Signed-off-by: Lukas Czerner Signed-off-by: "Theodore Ts'o"

libext2fs: adjust the description when copying a bitmap

2011-12-18T06:12:44Z

Label the copy of a bitmap as "copy of ..." so that the bitmap's description is more descriptive. Signed-off-by: "Theodore Ts'o"

e2fsck: use different bitmap types as appropriate

2011-12-18T06:12:44Z

Now that we have multiple backend implementations of the bitmap code, this commit teaches e2fsck to use either the most appropriate backend for each use case. Since we don't know for sure if we will get it all right, the default choices can be overridden via e2fsck.conf. The various definitions are shown here, with the current defaults (which may change as we add more bitmap implementations and as learn what works better). ; EXT2FS_BAMP64_BITARRAY is 1 ; EXT2FS_BMAP64_RBTREE is 2 ; EXT2FS_BMAP64_AUTODIR is 3 [bitmaps] inode_used_map = 2 ; pass1 inode_dir_map = 3 ; pass1 inode_reg_map = 2 ; pass1 block_found_map = 2 ; pass1 inode_bad_map = 2 ; pass1 inode_imagic_map = 2 ; pass1 block_dup_map = 2 ; pass1 block_ea_map = 2 ; pass1 inode_link_info = 2 ; pass1 inode_dup_map = 2 ; pass1b inode_done_map = 3 ; pass3 inode_loop_detect = 3 ; pass3 fs_bitmaps = 2 Signed-off-by: "Theodore Ts'o"

libext2fs: use the rbtree bitmap by default when initializing a file system

2011-12-18T06:12:44Z

This change causes the max resident memory of mke2fs, as reported by /usr/bin/time, to drop from 9296k to 5328k when formatting a 25 gig volume. Signed-off-by: "Theodore Ts'o"
