non-empty bad block list. Resize2fs now discards any blocks on the
badblock list which are no longer part of the filesystem as the result
of a filesystem shrink. (Note: this means that shrinking and then
enlarging a filesystem is no longer a reversible operation;
information about bad blocks in the part of the filesystem
which is to be chopped off will be lost.)
moving an inode, set the ctime field so that people using
dump/restore will backup the changed inode. Also update
the mtime and ctime of directories which get updated when
we need to move an inode.
release the bmap table. This significantly speeds up
resize2fs when shrinking or expanding a filesystem by a
very small number of blocks (which EVMS will do).
than the requested size, then we will attempt to
transparently extend the filesize in a sparse fashion by
writing a block at the end of the requested part of the
filesystem.
main.c (main), resize2fs.c (resize_fs), resize2fs.h: Change the
function prototype of resize_fs() so that it can modify
the new_size parameter with the actual new size of the
filesystem after the resize operation. (This can
sometimes be less than the requested new size if there
isn't enough space to create the necessary block group
metadata for that last bit of disk space.) Resize2fs now
prints the actual new size of the filesystem when it finishes.
Update copyright of files in preparation for release of resize2fs.
Also removed the (obsolete) beta-test check that had been in the code,
as well as the old spec files used to package the separate
distribution of resize2fs.
Makefile.in: No longer build resize2fs.static, since there's no real
point in it any more.
Modified Files:
ChangeLog Makefile.in extent.c main.c resize2fs.8.in
resize2fs.c resize2fs.h sim_progress.c test_extent.c
Removed Files:
e2fsprogs-1.12.spec pq.gif resize2fs.spec version.h
ext2fs.h, bitops.h: Add support for the Watcom C compiler to do inline
functions.
ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to evade a
potential problem with glibc's header files trying to spike out
linux/types.h.
ext2fs.h (ext2fs_resize_mem): Change the function prototype to include
the old size of the memory, which is needed for some braindamaged
memory allocation systems that don't support realloc().
badblocks.c (ext2fs_badblocks_list_add):
bb_inode.c (clear_bad_block_proc):
dblist.c (ext2fs_add_dir_block):
icount.c (insert_icount_el):
irel_ma.c (ima_put):
rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to pass
the old size of the memory to be resized to ext2fs_resize_mem().
ChangeLog, dirinfo.c:
dirinfo.c (e2fsck_add_dir_info): Update function to pass the old size
of the memory to be resized to ext2fs_resize_mem().
ChangeLog, extent.c, resize2fs.c:
resize2fs.c (adjust_superblock):
extent.c (ext2fs_add_extent_entry): Update functions to pass the old
size of the memory to be resized to ext2fs_resize_mem().
main.c (main): Check to make sure we can really resize this
filesystem. If there are compatible feature sets that we don't
support, we need to abort.
resize2fs.c: Change to use the new prototype required by
block_iterate2 (which uses blkcnt_t for the blockcount).
version.h, RELEASE-NOTES:
Interim commit of changes to date.
resize2fs.c (inode_scan_and_fix): If we are expanding the filesystem,
temporarily set rfs->old_fs->super->s_blocks_count to ultimate size of
the filesystem, to avoid catching an error on the block iterator.
resize2fs.c (blocks_to_move): Create the meta_bmap using the old
filesystem, not the new filesystem.
(get_new_block): Don't try checking the old block bitmap if the block
we're testing is beyond the boundaries of the old filesystem.
main.c (check_mount, main): Resize2fs now checks the size of the
partition, and uses this as a default new_size of the partition if one
is not specified. Resize2fs will not let you resize a mounted
partition.
resize2fs.c: Change how the progress function for the INODE_SCAN pass
is performed, so that the maximum size is never zero.
resize2fs.8.in: Updated man page.
Major reoganization of how resizing works. Functions in
ext2_block_move.c, and ext2_inode_move.c moved into resize2fs.c.
Multiple passes in those two files also combined into a single inode
scanning pass. Made the inode table moving function better handling
the case where it needs to abort mid-operation. When moving blocks
around, made the block allocation function preferentially avoid the
old group descriptor blocks, to make resize2fs more robust.
resize2fs.h: If EXT2_FLAT_INCLUDES is defined, then assume all
of the ext2-specific header files are in a flat directory.
ext2_block_move.c, ext2_inode_move.c, extent.c, resize2fs.c,
resize2fs.h: Rename variables named "new" to "new_block",
"new_inode", or "new_loc" to avoid C++ reserved word
clash.
ext2_block_move.c, ext2_inode_move.c, extent.c, resize2fs.c,
sim_progress.c: Use ext2fs_get_memory(),
ext2fs_free_memory(), et. al., instead of malloc() and
free().
ext2_block_move.c, ext2_inode_move.c, extent.c: Explicitly cast
all assignments from void * to be compatible with C++.
banalysis.c, banalysis.h, ext2_inode_move.c, ext2_block_move.c:
Change private to priv_data to avoid C++ namespace clash.
ChangeLog, badblocks.8.in:
badblocks.8.in: Add documentation for the -s option.
resize2fs.c, ext2_block_move.c ext2_inode_move.c: Only include printf
statements if RESIZE2FS_DEBUG is defined.
main.c: Don't read in the bitmaps since resize2fs.c does that.
e2label.c, mke2fs.c:
Adjust header files.
Allow people to set the version.h to something like 1.10-PLUS.
.del-inodemap.c~24510e64, main.c, resize2fs.c, resize2fs.h:
More interim work. All is functioning except progress meter.
bmove.c (ext2fs_move_blocks): New function which takes a bitmap of
blocks which need to be moved, and moves those blocks to another
location in the filesystem.
rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a bitmap,
make sure all of the new parts of the bitmap are zero.
bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap wasn't
being returned to the caller.
alloc_tables.c (ext2fs_allocate_group_table): Add new function
ext2fs_allocate_group_table() which sets the group tables for a
particular block group. The relevant code was factored out of
ext2fs_allocate_tables().
dblist.c (make_dblist): Adjust the initial size of the directory block
list to be a bit more realize (ten plus twice the number of
directories in the filesystem).
Check in interim work.
configure.in (rmakefile): Added (optional) private directory for resize2fs.
Makefile.in: Change recursive descent rules to check to see if a
directory exists before trying to make it.
Many files:
Initial checkin of work done to date.
