lib/ext2fs/ChangeLog

2000-12-14  Andreas Dilger  <adilger@turbolinux.com>

	* mkjournal.c: rename ext2fs_add_journal_fs() to the more descriptive
		ext2fs_add_journal_inode()

2001-01-01    <tytso@snap.thunk.org>

	* 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    <tytso@snap.thunk.org>

	* 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  <tytso@valinux.com>

	* 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    <tytso@snap.thunk.org>

	* 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    <tytso@snap.thunk.org>

	* test_io.c (test_write_blk, test_write_byte): Fix typos pointed
		out by Andreas Dilger.

2000-11-05    <tytso@snap.thunk.org>

	* 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    <tytso@snap.thunk.org>

	* 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    <tytso@snap.thunk.org>

	* 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.  This is an
		optional interface, which not all IO channels may
		implement.

	* unix_io.c (unix_write_byte):
	* test_io.c (test_write_byte): Add implementation of the
		write_byte function.

	* closefs.c (write_primary_superblock, ext2fs_flush): Add a new
		function which writes the primary superblock.  If the IO
		channel supports writing raw bytes directly, only fields
		which were modified are written to the disk.  This makes
		it safe(r) to use utilities like tune2fs on a mounted
		filesystem. 

	* freefs.c (ext2fs_free): Free the original superblock if it is
		available. 

	* openfs.c (ext2fs_open): Store a copy of the original superblock
		when opening it.

	* ext2fs.h: Add a field to store the original superblock in the
		ext2 context structure.

2000-10-24    <tytso@snap.thunk.org>

	* llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we
		don't need to use llseek).

2000-10-24    <tytso@valinux.com>

	* Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for
		creating an ext3 journal on a filesystem.

2000-08-21    <tytso@valinux.com>

	* ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code.

2000-08-22    <tytso@valinux.com>

	* unix_io.c: Make massive changes to support a multiple block
		writethrough cacheing.

	* ext2_io.h: Added flags field to the io_channel structure.

2000-08-19    <tytso@valinux.com>

	* 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.

2000-07-13    <tytso@valinux.com>

	* Release of E2fsprogs 1.19

2000-07-07  Theodore Ts'o  <tytso@valinux.com>

	* ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add
		EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the
		list of filesystem flags supported by the library.

2000-07-04  Theodore Ts'o  <tytso@valinux.com>

	* ext2fs.h: Update to include latest journalling additions to the
		superblock.

	* dll/jump.funcs: Add new jumptable entries for
		ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
		ext2fs_badblocks_equal.

	* 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).

2000-06-10  Theodore Ts'o  <tytso@valinux.com>

	* getsize.c (main): Add debugging code under #ifdef DEBUG

2000-05-27  Theodore Ts'o  <tytso@valinux.com>

	* mkdir.c (ext2fs_mkdir): Read the parent directory's inode
		earlier, so that if there's an error reading it, we can
		more cleanly back out of the operation.

2000-05-25    <tytso@snap.thunk.org>

	* getsize.c (ext2fs_get_device_size): Use open64() instead of
		open() if it exists.  Under linux, manually define the
		ioctl for BLKGETSIZE if it isn't already defined and it's
		safe to do so.

	* unix_io.c (unix_open): Use open64() instead of open() if it
		exists. 

	* llseek.c: Simplify header includes of unistd.h.  If lseek64 is
		available (and prototypes are defined) use it in
		preference to llseek.

	* Makefile: Add hack dependency rule so that parallel makes work
		correctly. 

2000-05-18  Theodore Ts'o  <tytso@valinux.com>

	* ext2fs.h: Add appropriate ifdef's to support C++ compilation.

2000-04-03  Theodore Ts'o  <tytso@valinux.com>

	* block.c: Readibility tweak in conditionals involving
		ctx->fs->flags.

	* ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
		how to define __s64 and __u64.  Turn off "compression is
		experimental" warning if the cpp macro
		I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.

2000-02-11    <tytso@snap.thunk.org>

	* ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
		Conditionally include Compression as a supported type if
		ENABLE_COMPRESSION (via --enable-compression) is turned on.

	* swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.

2000-02-08    <tytso@snap.thunk.org>

	* bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
		ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
		ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
		Change to return the previous state of the bit that is
		being marked or unmarked.  For speed optimization.
	
2000-02-02  Theodore Ts'o  <tytso@valinux.com>

	* getsize.c, ismounted.c: Remove unneeded include of linux/fs.h

	* swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
		needed any more; we know it will always be i_generation.
		Add support for swapping the high bits of the uid and gid.

1999-11-19    <tytso@valinux.com>

	* mkdir.c (ext2fs_mkdir): Only update the parent's inode link
		counts if the link was successful.  Patch suggested by
		jeremy@goop.org.

	* Makefile.in (distclean): Remove TAGS and Makefile.in.old from
		the source directory.

1999-11-10    <tytso@valinux.com>

	* Release of E2fsprogs 1.18

1999-11-08    <tytso@valinux.com>

	* 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.

1999-10-26    <tytso@valinux.com>

	* Release of E2fsprogs 1.17

1999-10-26    <tytso@valinux.com>

	* ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
		seem to handle ~0UL the same way as they used to.

1999-10-25    <tytso@valinux.com>

	* nt_io.c (_OpenNtName): Open the device using
		FILE_SYNCHRONOUS_IO_NONALERT instead of
		FILE_SYNCHRONOUS_IO_ALERT
		(nt_open): At the end of the device open routine, unlock 
		the drive but do not dismount it.

	* initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
		detect the Hurd OS.

1999-10-22    <tytso@valinux.com>

	* Release of E2fsprogs 1.16

1999-10-22    <tytso@valinux.com>

	* mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().

	* link.c (ext2fs_link): This call now uses the low three bits of
		the flags parameter to pass the directory filetype
		information; it will set the directory entry FILETYPE
		information if the filesystem supports it.

	* newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
		option is set, then create the '.' and '..' entries with
		the filetype set to EXT2_FT_DIR.

1999-09-24    <tytso@valinux.com>

	* nt_io.c: New file which supports I/O under Windows NT.

1999-09-07    <tytso@valinux.com>

	* ext2fs.h: Add new fields for journalling and define new
		feature bits used by newer filesystems: IMAGIC_INODES,
		HAS_JOURNAL, RECOVER.

	* expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
		we update the inode block count and size files so that the
		block count field is updated correctly when we create an
		indirect block.

1999-07-18  Theodore Ts'o  <tytso@valinux.com>

	* Release of E2fsprogs 1.15

1999-06-23    <tytso@valinux.com>

	* swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
		kernels that use i_generation instead of i_version.  Patch
		supplied by Jon Bright <sircus@sircus.demon.co.uk>.

1999-06-21    <tytso@valinux.com>

	* dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
		directory entry before calling the callback function.
		This should prevent some core dumps of insufficiently
		paranoid callback functions.

1999-05-29    <tytso@rsts-11.mit.edu>

	* ext2fs.h: Add feature definition for AFS IMAGIC inodes.

	* fileio.c (ext2fs_file_open): Remove obsolete comment stating
		that we don't handle writing yet (we do).  Fixed bug where
		we weren't allocating a big enough buffer for ext2_bmap.

1999-05-03    <tytso@rsts-11.mit.edu>

	* openfs.c (ext2fs_open): Check to make sure that the number of
		blocks per group is not zero --- if so, it must be a bad
		superblock!

1999-01-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* Release of E2fsprogs 1.14

1999-01-07  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
		the inode number is zero; if it's zero, return
		EXT2_ET_BAD_INODE_NUM.

1998-12-30  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
		of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
		header files.

Mon Jan  4 02:32:09 1999  Theodore Y. Ts'o  <tytso@mit.edu>

	* llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
 		non-Linux case to use EINVAL by default, unless it isn't
 		defined, in which case we use EXT2_ET_INVALID_ARGUMENT
 		instead.

1998-12-15  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* Release of E2fsprogs 1.13

1998-12-03  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* Makefile.in: Updated dependencies.

1998-09-22  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* initialize.c (ext2fs_initialize): Make sure that we allocate
		enough inodes so that we can make a valid filesystem.

1998-09-02  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* rw_bitmaps.c: Fixed signed/unsigned warnings.

	* fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
		function declaration.

	* dblist.c (make_dblist): Add safety check in case the dblist
		pointer passed in is null (in which case, assign it to
		fs->dblist).  Fixed some signed/unsigned warnings.

	* bmap.c: Make addr_per_block be of type blk_t to avoid
		signed/unsigned warnings.

	* namei.c (ext2fs_follow_link): Remove uneeded extern from the
		function declaration.

	* get_pathname.c (get_pathname_proc): Use return value from
		ext2fs_get_mem, instead of checking if &gp->name is
		NULL.

	* dir_iterate.c (ext2fs_process_dir_block): 
	* dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
		from the function declaration.

	* block.c (ext2fs_block_iterate2): If the read_inode call fails,
		return the error directly instead of jumping to the
		cleanup routine, since we don't need to do any cleanup.

	* alloc_table.c (ext2fs_allocate_group_table): Make this
		function take a dgrp_t for its group argument.

	* ext2fs.h: Make dgrp_t an __u32 type, and make
		fs->desc_group_count be of type dgrp_t.

1998-07-27  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
		than 10 blocks when we need to expand the size of the
		badblocks list.

1998-07-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* Release of E2fsprogs 1.12

1998-06-30  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* closefs.c (ext2fs_flush): Update the s_block_group_nr field as
		appropriate for all of the block group copies, so that
		it's clear where the beginning of the filesystem is on the
		disk.  (For when the partition table gets scrod.)

	* ext2fs.h: Change the name of the feature from
		EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
		EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).

1998-06-18  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* inode.c (get_next_blockgroup): Fix bug where if
		get_next_blockgroup() is called early because of a missing
		inode table in a block group, the current_inode counter
		wasn't incremented correctly.

1998-06-16  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* read_bb.c (ext2fs_read_bb_inode): Make function more robust
		against a completely trashed bad block inode.

1998-06-10  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
		the stride length hits a bad value, we retry the block
		allocation starting at the beginning of the block group.

	* ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
		expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
		e2_blkcnt_t to avoid collision with LFS API.

1998-05-01  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
		way that avoids overflows on disk sizes greater than 4GB.

1998-04-28  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
		return type for comparison functions for qsort.

	* dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
		declaration.

1998-04-26  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* 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(). 

1998-03-30  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* Makefile.in: Change to use new installation directory variables
		convention.  Fix uninstall rules to take $(DESTDIR) into
		account.

1998-03-29  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* 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.

1998-03-23  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* block.c (ext2fs_block_iterate3): Make the ref_offset field
		contain the offset into the inode.i_blocks array when
		ref_block is zero.  Since we haven't done a formal
		release of e2fsprogs since block_iterate2 was first
		introduced, I removed block_iterate2, and renamed
		block_iterate3 to be block_iterate2.

	* bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
		expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
		use of block_iterate and block_iterate2 to
		block_iterate2 with the new prototype for the
		interator function.  (using blkcnt_t forr blockcount)

1998-03-21  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap, 
		s_prealloc_blocks, s_prealloc_dir_blocks).  Added
		conditional defines of new features COMPAT_DIR_PREALLOC,
		RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
		INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE.  Changed
		the library to declare that we support COMPAT_DIR_PREALLOC, 
		INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.

	* fileio.c: Rename function ext2fs_file_llseek to be
		ext2fs_file_lseek, which is more accurate.

	* block.c: Add new function ext2fs_block_iterate3 which calls
		the iterator function with the blockcount argument of
		type blkcnt_t.  This version of the function is
		allowed to handle large files; the other fucntions are
		not.

	* ext2fs.h: Add new type blkcnt_t

	* ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG

	* block.c (ext2fs_block_iterate2): Fix bug where the block count
		field wasn't getting correctly incremented for sparse
		files when the indirect or doubly-indirect block
		specified in the inode was zero.

Sun Mar  8 22:42:47 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* unlink.c (unlink_proc): 
	* lookup.c (lookup_proc): 
	* link.c (link_proc): 
	* get_pathname.c (get_pathname_proc): 
	* dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
		from dirent->name_len, so it can be used for other
		purposes.

	* ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
		and indicate that we have support for this incompatible
		option.

Mon Feb 23 08:46:33 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

Fri Feb 20 23:58:01 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
 		number of directories when the block group information is
 		unreliable.

1998-02-20  Theodore Y. Ts'o  <tytso@edt.mit.edu>

	* inode.c (ext2fs_get_next_inode): Always do the check to see if the
		inode table is missing so that we catch the case where the
		first block group is missing.

	* getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
		needed.

Mon Feb 16 16:16:00 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* ext2_io.h, ext2fs.h: Protect against being included multiple times.

	* bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"

	* test_io.c (test_flush): Add a debugging printf when the flush
		method is called.

	* rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
		read in, return right away.

Sun Feb  1 08:20:24 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* bitops.h: Don't try to do i386 inline asm functions if the
 		compiler isn't GCC.

	* inode.c (ext2fs_open_inode_scan): Initialize the group variables
		so that we don't need to call get_next_blockgroup() the

		unsigned value).

	* icount.c (insert_icount_el): Cast the estimated number of inodes
		from a float to an ino_t.

	* alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

		get_pathname.c, getsize.c, icount.c, initialize.c,
		inline.c, inode.c, irel_ma.c, ismounted.c, link.c,
		lookup.c, mkdir.c, namei.c, native.c, newdir.c,
		openfs.c, read_bb.c, read_bb_file.c, rs_bitmap.c,

	* dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
		avoid C++ namespace clash.

	* bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
		avoid C++ namespace clash.

	* ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
 	 	irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
 	 	ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
 	 	unlink.c: Change private to be priv_data (to avoid C++
 	 	namespace clash)

Fri Nov 28 09:26:31 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
		paranoid about validating the directory counts from the
		block group information.

	* all files: Don't include stdlib.h anymore; include it in
		ext2_fs.h, since that file requires stdlib.h

Thu Nov 20 16:07:38 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* expanddir.c (ext2fs_expand_dir): Check to make sure the block

		of int.

	* alloc.c alloc_tables.c badblocks.c bb_compat.c bb_inode.c
 	 	bitmaps.c block.c bmove.c brel_ma.c check_desc.c closefs.c

	* dblist.c (ext2fs_dblist_count): Added new function which returns
		the number of directory blocks in dblist.

Sat Jun 14 01:39:13 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* unix_io.c (unix_flush): Make the io_channel flush function do a
		fsync to flush the kernel buffers to disk.

Wed Jun 11 18:25:31 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
		current inode number wasn't being set by the

		wasn't being returned to the caller.

	* alloc_tables.c (ext2fs_allocate_group_table): Add new function

	* dblist.c (make_dblist): Adjust the initial size of the directory
 		block list to be a bit more realistic (ten plus twice the
 		number of directories in the filesystem).

Thu May  8 22:19:09 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* badblocks.c (ext2fs_badblocks_list_test): Fix bug where
 		ext2fs_badblocks_list_test would test the list (and exceed
 		array boundaries) if there were no bad blocks on the bad
 		blocks list.  (Showed up when user tried: mke2fs -c -b 4096).

	* alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
		inode bitmaps at staggered locations across the block
		groups, to avoid concentrating the bitmaps on a small
		number of disks when using striped RAID arrays.

	* initialize.c (ext2fs_initialize): By default, choose the maximum
		possible number of blocks per group (based on the size of
		the bitmaps in the blocksize).

Fri Apr  4 11:28:16 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* initialize.c (ext2fs_initialize): Add support for
		EXT2_COMPAT_SPARSE_SUPER feature.

		or not the superblock should be written out for the block
		group.

	* icount.c (ext2fs_create_icount): Change function so that it also
		takes a new argument which contains a "hint" icount
		structure.  This "hint" icount allows the create function
		to set up the sorted list in advance.  This reduces

		these inodes into the list later.
	
	* icount.c (ext2fs_icount_validate): New function which validates
		that the icount structure's rep invariant.

	* icount.c (get_icount_el): Completely revamped implementation
		to subsume put_icount_el().  Put_icount_el() used to
		use an O(N) implementation to insert in the middle
		of the icount list.  It now uses a O(ln N) to search
		for where the icount should be inserted, and then uses
		a memcpy to move the list down (instead of a for loop).
	
	* icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
 		ext2fs_icount_increment, ext2fs_icount_decrement): Check
 		to see if the inode is within bounds; if it isn't, return
 		EINVAL.

	* bitops.h (ext2fs_test_generic_bitmap): Fix error message given
 		when a bad inode number is passed to test_generic_bitmap
 		to be EXT2FS_TEST_ERROR instead of the wrong
 		EXT2FS_UNMARK_ERROR.

Wed Mar 12 13:32:05 1997  Theodore Y. Ts'o  <tytso@mit.edu>

	* alloc.c (ext2fs_get_free_blocks): Change routine to use
	 	ext2fs_fast_test_block_bitmap_range().

 		ext2fs_test_block_bitmap_range: New inline functions which
 		test to see whether a contiguous range of blocks is
 		available.

		names to ext2fs_badblocks_*()

	* unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
	 	link.c (since e2fsck doesn't use ext2fs_unlink()).

	* rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
 		bitmap resizing routine moved from bitmaps.c, since e2fsck
 		doesn't need to use this function.

	* lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
		since e2fsck only needs ext2fs_lookup.

Mon Feb  3 10:11:40 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
		already set; this is needed so that programs like dump
		which use the inode scan functions will deal with
		filesystems that have bad blocks in the inode table.

Sun Feb  2 00:17:36 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* ext2fs.h (struct_badblocks_list, struct_badblocks_iterate): 
		Moved to ext2fsP.h, since it doesn't need to be part of
		the public interface.

	* dir_iterate.c: Move ext2_dir_iterate out of namei.c.

Sat Feb  1 10:14:55 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* dblist.c (ext2fs_get_num_dirs): New file, which implements a
 		directory block list abstraction.  (Code moved from
 		e2fsck).

	* ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
		to inode.c (since no one else should be peeking inside it!)

	* valid_blk.c (ext2_inode_has_valid_blocks): New function.

	* openfs.c (ext2fs_open): Check the feature set in the ext2
		superblock, and refuse to open filesystems if they contain

Sun Jan 12 11:31:46 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* block.c (ext2fs_block_iterate2): Added new function
	 	ext2fs_block_iterate2 which changes the function
	 	signature of the callback function to include the
	 	referencing block and offset.

	* inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
	 	ext2fs_inode_scan_goto_blockgroup which allows an
	 	application to jump to a particular block group while
	 	doing an inode scan.

Wed Jan  1 23:50:12 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* dirblock.c: Include string.h, since we use memcpy().

Tue Dec  3 12:27:29 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
		a long not an int; this doesn't matter on i386 machines,
		but it does on Alpha's.

 		ext2fs_get_next_inode): Don't treat a missing inode table
 		as permanent error.  Return MISSING_INODE_TABLE, but as an
 		advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.

	* rw_bitmaps.c (ext2fs_write_block_bitmap,
 	 	ext2fs_write_inode_bitmap): If the inode or block bitmap
 	 	block is zero, then don't write out the inode or block
 	 	bitmap.  The idea here is to avoid stomping on the
 	 	superblock.
		(read_bitmaps): If the inode or block bitmap block is
	 	zero, then fill in that portion of the inode or block
	 	bitmap with all zeros.

	* inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
 		blocks in inode table when the inode table size is
 		non-standard (and can therefore span blocks).

	* alloc_tables.c (ext2fs_allocate_tables): New function which
		performs the part of mke2fs's job of allocating the 
		filesystem tables.

	* test_io.c (test_close): IO manager which is used for testing
	 	purposes.

		inode table to get_next_blocks().

	* ext2fs.h: Add the badblocks list to the ext2_filsys entry

	* badblocks.c (badblocks_list_add, badblocks_list_test): Add
 		blocks to the badblock list in sorted order.  This allows
 		badblocks_list_test to be coded using a binary search for
 		speed.

Tue Oct  8 02:02:03 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* block.c (ext2fs_block_iterate): Fixed bug which caused
 		block_iterate to fail to handle HURD created filesystems;
 		it tested the inode translator field before the inode was
 		loaded.

	 	superblock.

	* namei.c (ext2fs_follow_link): New function.
		(ext2fs_namei): Extended to have support for chasing
 		symbolic links.  ext2fs_namei() still returns an inode
 		which is a symbolic link.  Symbolic links are only chased
 		while resolving the containing directory.  To chase
 		symbolic links of the final result, use
 		ext2fs_follow_link().

	* initialize.c (ext2fs_initialize): On systems where the byte
		order is not i386 compatible, set the swap_byte flag.

	* inode.c (inocpy_with_swap): Check to see if inode contains a
		fast symlink before swapping the inode block fields.  This
		required adding a new argument to inocpy_with_swap to
		determine whether the mode field is in host order or not.

Wed Aug 21 00:45:42 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
		the sparc, if EXT2_STD_BITOPS set, use the standard
		i386-compatible bitmask operations, instead on the

Fri Aug  9 11:11:35 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* block.c (ext2fs_block_iterate): Cause block iterator to return
		the HURD translator block (along with everything else).
		If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
		iterator, then don't return any meta data blocks
		(including the HURD translator).

Sun May 19 15:39:03 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* openfs.c (ext2fs_open): If the blocksize in the superblock is
		zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
		that's a basic value that must be correct for the rest of
		the library to work.

	* ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
	 	code.

Thu May 16 11:12:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

		Move these functions to freefs.c.

	* closefs.c (ext2fs_flush): If swapping blocks, clear the group
		descriptors shadow memory to keep purify quiet.  (This
		also has the nice benefit that the unused portion of the
		shadow descriptors are zeroed out.)

	* dirblock.c (ext2fs_write_dir_block): We need to use

		block_iterate_tind): Byte swap the block addresses if
		EXT2_SWAP_BYTES is set (and swap them back before writing

	* bitops.h (ext2_swab16, ext2_swab32): Added new functions for
		doing byte swapping.

	* ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

	* block.c (block_iterate_ind, block_iterate_dind, 
		block_iterate_tind): Don't recompute block_nr each loop;
		just increment it!  Factor check of BLOCK_FLAG_APPEND out

		optimization helps.)

Thu Jul 13 08:02:45 1995    <tytso@rsx-11.mit.edu>

		and lseek is not supported should be EINVAL, not -EINVAL.

Thu Jun 15 23:43:02 1995  Remy Card  <card@bbj>

	* Makefile.in: Added support for ELF shared libraries.

		which may have a different value for S_IFDIR.

Sat Jun 10 23:47:05 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>

	* bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();

		illegal block or inode number is passed in, return instead
		of trying to test, set, or clear the bit.

Mon Nov  7 21:32:33 1994  Remy Card  <card@bbj>

		both for io_channel structure and unix_private_data
		structure.

	* openfs.c (ext2fs_open): Add check for io_manager structure's
		magic number.

	* rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
		ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
		ext2fs_read_bitmaps, ext2fs_write_bitmaps): 
	* read_bb.c (ext2fs_read_bb_inode): 
	* read_bb_file.c (ext2fs_read_bb_FILE): 
	* newdir.c (ext2fs_new_dir_block): 
	* namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei): 
	* link.c (ext2fs_link, ext2fs_unlink): 
	* inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
		ext2fs_write_inode, ext2fs_get_blocks, 
		ext2fs_check_directory): 
	* get_pathname.c (ext2fs_get_pathname): 
	* expanddir.c (ext2fs_expand_dir): 
	* block.c (ext2fs_block_iterate): 
	* bitmaps.c (ext2fs_allocate_inode_bitmap, 
		ext2fs_allocate_block_bitmap): 
	* bb_inode.c (ext2fs_update_bb_inode): 
	* alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks): 
	* check_desc.c (ext2fs_check_desc): 
	* closefs.c (ext2fs_close, ext2fs_flush): 
	* freefs.c (ext2fs_free): Add check for ext2_filsys magic number.

	* Makefile:
	* ext2fs.h:
	* openfs.c:
	* check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
	openfs.c into its own file.

	* ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
	structure magic numbers.

	* closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
	the EXT2_VALID_FS flag in the backup superblock blocks, so that if
	someone uses the -b option to specify the use of the backup
	superblock --- this usually means that the main superblock is
	toast.  :-)

	* ext2fs.h: 
	* ext2_err.et (EXT2_ET_REV_TOO_HIGH): 
	* openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
	revision level to the superblock.

Sun Aug 21 00:50:08 1994  Theodore Y. Ts'o  (tytso@rt-11)

	* ext2fs.h:
	* bitmaps.c:
	* bitops.c
	* bitops.h:
	* openfs.c:
	* initialize.c: Completely revamped the inode and block bitmap
	structures, so that they can be better chance of being extensible
	in a shared library.  They are now their own type, instead of
	being a char *.  Also, the function signatures of
	ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
	ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
	ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
	changed to eliminate the ext2_filsys argument, since it is no
	longer necessary.

Wed Aug 17 21:46:44 1994  Remy Card  (card@bbj)

	* unix_io.c (unix_read_blk and unix_write_blk): use the llseek
	system call if available.

	* llseek.c: new file.  This is the stub calling the llseek system
	call which allows supports for 2GB+ file systems.

	* initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
	the creator operating system.

Wed Aug 17 10:03:24 1994  Theodore Y. Ts'o  (tytso@rt-11)

	* initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
	the group descriptor statistics in addition to everything else.
	This relieves mke2fs of the responsibility of doing it.

	* bitops.c, bitops.h: Add assembly inline functions for the 68000.
	Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
	not the generic C function equivalents should be included or not.

	* openfs.c (ext2fs_open): If a superblock is specified, then use
	the backup group descriptors that go along with this superblock,
	instead of using the primary group descriptors.  This allows
	e2fsck to recover filesystems where the primary group descriptors
	have been trashed.
