the superblock and block group descriptors into two functions:
ext2fs_reserve_super_and_bgd, found in lib/ext2fs/alloc_sb.c, and
ext2fs_super_and_bgd_lock, found in lib/ext2fs/close.c.
Change e2fsck/pass1.c (mark_table_blocks), lib/ext2fs/closefs.c
(ext2fs_flush), lib/ext2fs/initialize.c (ext2fs_initialize),
and misc/dumpe2fs.c (list_desc) to use these functions.
e2fsck/ChangeLog
pass1.c (mark_table_blocks): Use the new function
ext2fs_reserve_super_and_bgd to calculate the blocks to be
reserved.
lib/ext2fs/ChangeLog
closefs.c (ext2fs_super_and_bgd_loc): New function which
centralizes the calculation of the superblock and block
group descriptors.
(ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
out where to write the superblock and block group
descriptors.
alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
reserves space in the block bitmap using
ext2fs_super_and_bgd_loc.
initialize.c (ext2fs_initialize): Use
ext2fs_reserve_super_and_bgd to initialize the block bitmap.
misc/ChangeLog
dumpe2fs.c (list_desc): Use ext2fs_super_and_bgd_loc to
determine the locations of the superblock and block group
descriptors.
device is larger than the default block size, then use the
sector size of the device as the default block size.
getsectsize.c (ext2fs_get_device_sectsize): New function which
returns the hardware sector size (if it is available).
instead of <com_err.h>, so the current version of the header file
is used.
Add a --build-tree option to compile_et to make sure that it uses
the et_?.awk files from the build tree.
Remove legacy support for varargs.h, K&R C, and pre-POSIX signal
support. Also fixed gcc -Wall nits.
Disable certain tests that depend on the byteswapping functions
being present so that "make check" succeeds even if --disable-swapfs
is passed to the configure script.
Revert the shlibs hack.
Makefile.in: Remove inode_io.o from the standard object files
in libext2fs, and only build it if debugfs is enabled
(it requires fileio.o, which is only built if
--disable-debugfs isn't specified to configure).
an I/O object.
Export ext2_file_flush as a public interface.
Also minor cleanups to tighten code in other I/O abstractions, and to
mark a void * pointer as const in the ext2_file_write interface.
Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
which will return deleted directory entries.
ext2fs_dir_iterate2 takes a new callback function which
is identical with the one used by
ext2fs_dblist_dir_iterate(). If the directory entry is
deleted, the callback function will be called with the
entry paraemter set to DIRENT_DELETED_FILE.
Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
ext2fs_block_alloc_stats): New functions which update
block/inode allocation statistics in the bitmaps, block
group descriptors, and superblock.
mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
expanddir.c (expand_dir_proc), bb_inode.c
(clear_bad_block_proc, set_bad_block_proc,
ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
Update to use new block/inode allocation statistics.
- Renamed linux/list.h to be linux/linked_list.h to work around a
problem caused by diet libc insistence to search the kernel
header files ahead of all other files in the include path,
including the user specified include files.
- Worked around a bug in diet libc which core dumps when using
putc with stderr by using fputs instead. As a bonus, this
also shaved a few bytes off of com_err.o.
- Fixed a real bug in debugfs which was detected because diet libc
was more sensitive than glibc when incorrectly using fclose()
where pclose() is required.
Makefile.in: Fix bug in installation of ext2_types.h. It is a file
which is generated and is therefore found in the build directory, not
source directory.
setsuper.c: Add s_lastcheck field to the fields which can be modified
using set_super_value. (Suggested by Andreas Dilger)
ChangeLog, Makefile.in:
Makefile.in (HFILES): Add ext2_types.h to the list of files which
should be installed.
Makefile.in: Limit some .o files from being included into the library
if --disable-debugfs, --disable-swapfs, --disable-imager, or
--disable-resizer are used.
Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap to
gen_bitmap.c as normal functions. (This saves space and doesn't
significantly change the speed of e2fsck on a P-III.)
ChangeLog:
Add missing log entry for unix.c.
Makefile.in: Remove the dependence on the libe2p library.
mkjournal.c (ext2fs_add_journal_inode): Replace use of fsetflags with
direct usage of the ioctl/fchflags so that we don't have to depend on
the libe2p library.
Makefile.in: Move include/asm/types.h.in to lib/ext2fs/ext2_fs.h.in.
wordwrap.pl: Add some rules which help fix up the dependencies.
Many files:
Move include/asm/types.h.in to lib/ext2fs/ext2_fs.h.in.
ismounted.c (check_mntent): Check /proc/mounts on Linux systems before
checking /etc/mtab. The EXT2_MF_READONLY flag is now set from the
/etc/mtab options field for all filesystems, not just the root
filesystem. Add debugging code to make it easier to test
ext2fs_check_if_mounted().
bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly inline
functions.
tst_byteswap.c: New function to test the byteswap functions. Add to
regression test suite.
MCONFIG.in: Change --enable-gcc-wall handling so that it's no longer a
configure option, but something which is done when the developer uses
the command "make gcc-wall".
configure.in: Remove test for ino_t, since we don't use it any more
(we always use our own ext2_ino_t). Remove --enable-gcc-wall support.
Add test for sys/ioctl.h
.del-types.h.in~ca55114a:
Remove definition of ino_t
ChangeLog, Makefile.in, ext2fs.h, flushb.c, jump.funcs:
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.)
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.
.del-types.h.in~ca55114a:
Change what we use to protect the header file to be _ASM_TYPES_H
instead of _LINUX_TYPES_H. (Needed to make libc5 builds happy).
version.h:
Update for WIP release.
jfs_e2fsck.h, jfs_user.h: Replaces jfs_compat.h. The jfs.h file has
been moved to the include/linux directory.
journal.c, revoke.c, recovery.c: Updated files from Stephen to support
the V2 superblock and revoke processing. The journal.c and revoke.c
files are copies from the ext3 kernel source.
Makefile.in: Added revoke.c to the list of source/object files.
Makefile.in:
Fix up some mistakes in the source file list, and regenerate the
dependencies.
Update Makefile dependencies.
ChangeLog, jfs.h:
jfs.h: Remove excess #include of JFS_DEBUG. Not needed for e2fsprogs,
since we optioanlly define it in the configuration file system.
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.)
ChangeLog, Makefile.in, e2image.c:
e2image.c, Makefile.in: New program which saves ext2 metadata to a
file for people who need a last-ditch saving throw.
finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which
provides the function ext2fs_find_block_device(). This function
returns the pathname to a block device, given its device number.
tst_badblocks.c: Update test program to test ext2fs_read_bb_FILE2 and
ext2fs_write_FILE.
write_bb_file.c (ext2fs_write_bb_FILE): New function which writes out
bad blocks list to a file.
read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which changes
the callback function to take two additional arguments; a private
blind pointer supplied by the caller, and pointer to a char *
containing a pointer to the invalid string.
badblocks.c (ext2fs_badblocks_equal): Add new function which returns
true if two badblocks list are equal.
Makefile.in: Remove explicit link of -lc in the shared library. (It
shouldn't be necessary, and is harmful in some cases).
jump.funcs:
dll/jump.funcs: Add new jumptable entries for ext2fs_write_bb_FILE,
ext2fs_read_bb_FILE2, and ext2fs_badblocks_equal.
Makefile.in (distclean): Remove TAGS and Makefile.in.old from the
source directory. Also, when making the .exclude file for the
source_tar_file, exclude those two files as well.
Makefile.in (distclean): Remove TAGS and Makefile.in.old from the
source directory.
Makefile.in (tst_badblocks): Add freefs.o to the object list, since
ext2fs_badblocks_list_free was moved to freefs.c.
tst_badblocks.c: Use the newer badblocks API names. Add duplicate
blocks to the test inputs to test dealing with adding blocks which are
already in the badblocks list.
badblocks.c (ext2fs_badblocks_list_add): If appending to the end of
the list, use a shortcut O(1) operations instead of an O(n) operation.
(Idea suggested by David Beattie.)
freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead of
badblocks_list_free(), to save a procedure call.
MCONFIG.in (BUILD_CC):
configure.in (BUILD_CC): If cross compiling, find the native C
compiler and set it to BUILD_CC so that we can successfully build
util/subst.
ChangeLog, Makefile.in:
Makefile.in (subst): Build subst using $(BUILD_CC), since it's a
helper program which must be built using the native C compiler during
a cross-compilation.
Makefile.in:
Update dependencies.
pass3.c (get_lost_and_found): If the filesystem is not opened
read-only, then force /lost+found to be created if it is not present.
problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen operation.
ChangeLog, Makefile.in:
Makefile.in: Updated dependencies.
ChangeLog, fsck.c:
fsck.c (load_fs_info): Parse /etc/fstab ourselves, instead of relying
on getmntent(). This has the advantage of allowing us to properly
handle missing pass numbers correctly.
ChangeLog, configure.in:
configure.in: Add paths.h to header files for which we search.
ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform with
32 bit longs, then we need to manually define __s64 and __u64, since
the current kernel header files don't define these if __STRICT_ANSI__
is defined. This is a problem if we are compiling with full GCC
warnings, since we do need 64 bit support.
Makefile.in (OBJS): Remove bmove.o from files to be built, since we're
not using ext2fs_move_blocks() and there is some question as to its
usefulness in its current form.
bmap.c (block_bmap): Remove unused function.
bmove.c (process_block): Fix -Wall warning.
ChangeLog, debugfs.c, debugfs.h, dump.c:
debugfs.h: Add declaration for do_dirty_filsys() to prevent -Wall
warnings.
debugfs.c (copy_file):
dump.c (dump_file): Fix -Wall warning caused by signed/unsigned mismatch.
Makefile.in, tst_getsize.c: Added new file which is used to test the
ext2fs_get_device_size function.
ext2_err.et.in (EXT2_ET_UNIMPLEMENTED): Added new error code.
