2011-07-09debugfs: add a new debugfs command 'blocks'Theodore Ts'o4-0/+37
The blocks command prints out the blocks used by a particular inode, in a format which is useful for test suite automation. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2011-07-08misc: use EXT2_I_SIZE() consistently to get sizeAndreas Dilger3-16/+7
Use the EXT2_I_SIZE() macro consistently to access the inode size. The i_size/i_size_high combination is open coded in several places. Signed-off-by: Andreas Dilger <adilger@whamcloud.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2011-06-11ext2fs: Handle internal journal over 2^32 bytesAndreas Dilger1-0/+1
The write_journal_inode() code is only setting the low 32-bit i_size for the journal size, even though it is possible to specify a journal up to 10M blocks in size. Trying to create a journal larger than 2GB will succeed, but an immediate e2fsck would fail. Store i_size_high for the journal inode when creating it, and load it upon access. Use s_jnl_blocks[15] to store the journal i_size_high backup. This field is currently unused, as EXT2_N_BLOCKS is 15, so it is using s_jnl_blocks[0..14], and i_size is in s_jnl_blocks[16]. Rename the "size" argument "num_blocks" for the journal creation functions to clarify this parameter is in units of filesystem blocks and not bytes.

2011-06-11debugfs: fix icheck finding blocks used for xattrsAndreas Dilger1-2/+4
This was an "uninitialized variable" warning, but it turns out to be a real bug. Without this change, it is not possible to use "icheck" to find blocks that are used for the i_file_acl (xattr) block. Signed-off-by: Andreas Dilger <adilger@whamcloud.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2011-06-11misc: clean up compiler warningsAndreas Dilger3-3/+5

2011-05-14debugfs: document htree-related commands in man pageEric Sandeen1-0/+21
The debugfs commands dirsearch, dx_hash, and htree_dump were never documented in the man page. Do so. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2011-05-14debugfs: remove unused htree_dump "-l" argumentEric Sandeen1-24/+1
The long_opt / -l argument was apparently never implemented, so remove it and associated argument parsing. This slightly changes the (undocumented) behavior because it no longer defaults to cwd if no filespec is specified...

2011-03-18add new superblock field: s_overhead_blocksTheodore Ts'o1-0/+1
It turns out that it's very hard to calculate overheads in the face of clustered allocation (bigalloc). This is because multiple metadata blocks from different block groups can end up in the same allocation cluster. Calculating the exact overhead requires O(all block bitmaps) in memory, or O(number of block groups**2) in time. So we will calculate this at mkfs time and stash it in the superblock.

Extend the stat command to display more detailed extent information if the file uses extent mapping instead of displaying the block map using the block_iterate funtion.

2009-07-02Add support for configure --enable-verbose-makecmdsTheodore Ts'o1-13/+13
Some people don't want to see the concise "kernel-style" make output. This configure option allows build engines that want to see the full set of commands executed by the makefile to get what they want. Most people will find this more distracting than useful, unless they need to debug the Makefiles. (It is not necessary to rerun configure to enable this verbose make output temprarily; if a developer wants to do a quick debug of a directory's makefile, he or she can simply edit the definition of the $(E) and $(Q) variables in the Makefile; instructions can be found in the MCONFIG file which is included in at the beginning of every Makefile.)

2009-07-01Fix Makefile dependencies for libcom_errTheodore Ts'o1-1/+2
The e2fsprogs makefiles were using the same Makefile variable LIBCOM_ERR for the link-line arguments as well as the dependencies. Since LIBCOM_ERR can now include non-file arguments such as "-lpthread", we need to use a separate DEPLIBCOM_ERR variable that only has build file dependencies. Do the same thing for STATIC_LIBCOM_ERR and PROFILED_LIBCOM_ERR. Addresses-Sourceforge-Patches: #2813809 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2009-06-21Fix encoding for rec_len in directories for >= 64k blocksize file systemsTheodore Ts'o1-6/+17
Previously e2fsprogs interpreted 0 for a rec_len of 65536 (which could occur if the directory block is completely empty in 64k blocksize filesystems), while the kernel interpreted 65535 to mean 65536. The kernel will accept both to mean 65536, and encodes 65535 to be 65536. This commit changes e2fsprogs to match. We add the encoding agreed upon for 128k and 256k filesystems, but we don't enable support for these larger block sizes, since they haven't been fully tested.
