Tue Feb  4 04:26:54 1997  Paul H. Hargrove  <[e-mail]>

	* version.c, README.sgml:
	Bump version to "pre-0.8-4".

Mon Feb  3 23:18:45 1997  Paul H. Hargrove  <[e-mail]>

	* inode.c:
	Make header files always writable when the afpd mount option is given.
	Otherwise it is impossible to unlock a locked file.

	* TODO, inode.c:
	Let afpd think chmod() always succeeds, so "New Folder" works right.

	* super.c:
	The 'afpd' mount option now makes 'fork=n,names=n' the default.

	* TODO:
	List the current known afpd-compatibility problems as bugs.

	* file_hdr.c:
	Make certain date changes through header files get written to disk.

Sat Feb  1 02:24:12 1997  Paul H. Hargrove  <[e-mail]>

	* mdb.c:
	Work around for Linux rounding device sizes to 1k increments.

	* README.sgml:

Sat Dec 28 20:41:01 1996  Paul H. Hargrove  <[e-mail]>

	* TODO:
	Add ioctl() interface as a "missing feature."

	* dir_nat.c:
	Finish implementing the afpd-compatibility
	mode using the new 'afpd' mount option.

	* hfs_fs_sb.h, super.c:
	Add new 'afpd' mount option.

	* TODO, README.sgml:
	Optimistically document the hybrid CD problem as fixed.

	* part_tbl.c:
	Fix the partition code so at least some of the hybrid
	CDROMs that were previously rejected are now accepted.

	* hfs.h:
	Make fs_start a 32-bit integer rather than 16-bits.
	The 16-bit value would overflow if a partition started
	beyond the 32M mark (e.g. the Executor 2 Beta 1 CDROM).

	* extent.c:
	Fixed a typo in an error message.

Tue Dec 10 14:43:46 1996  Paul H. Hargrove  <[e-mail]>

	* dir_nat.c:
	Merge in the (still dormant) afpd-compatibility changes.

	* inode.c:
	Make the .AppleDouble directory writable (again).

	* version.c, README.sgml:
	Bump version up to "pre-0.8-3".

	* hfs_fs.h, file_cap.c, file_hdr.c:
	Move AFP constants to hfs_fs.h and prefix them with "HFS_".

	Back-out changes that allowed writing to the .AppleDouble directory.

	* Makefile:
	Update rules for linuxdoc-sgml v1.5.

	* extent.c:
	Fixed serious bug in decode_extent() with handling of empty extents.

	* file.c:
	Rewrote hfs_getblk().
	It will no longer hang if hfs_extent_map() is buggy.
	Also halves the worst-case number of calls to hfs_extent_map().

	* extent.c:
	Fixed serious bug in decode_extent() with handling of empty extents.

	* hfs_fs.h:
	Small change so the PPC (and maybe other architectures?)
	pick up the prototypes for the user-space access functions.

	* super.c, file_cap.c, file_hdr.c, hfs_fs.h, file.c:
	Updated for new user-space memory interface.

	Also allows compilation with 2.1.x kernels.

Thu Sep 19 10:28:43 1996  Paul H. Hargrove  <[e-mail]>

	* README.sgml, version.c:
	Bump version up to "pre-0.8-2".

	* TODO:
	Reformat the To Do list introducing prioritized categories.

	* file_hdr.c, file.c:
	Move comments about mmap() for headers from file.c to file_hdr.c.
	Also revise the reasoning for not yet having it implemented.

	* dir_nat.c, dir_cap.c, dir_dbl.c:
	Remove 'hfs_' prefix from names of some purely local functions.

	* dir_dbl.c, TODO:
	Under AppleDouble make create(), mkdir(), mknod(), unlink(), rename()
	and rename() check against header files when arguments start with '%'.

	* super.c, hfs_fs_sb.h, hfs_fs.h, dir_dbl.c, dir_nat.c, dir_cap.c,
	  dir.c, README.sgml:
	Fix problem that prevented creating %RootInfo or .rootinfo in all

Wed Sep 18 23:07:45 1996  Paul H. Hargrove  <[e-mail]>

	* hfs_fs.h, file_cap.c:
	Comment the definition of (struct hfs_cap_info).

	* version.c, README.sgml:
	Bump version up to "pre-0.8-1" and update the "How can I write?" FAQ.

	* file_hdr.c:
	Implement hdr_write() and hdr_truncate()!!

	* hfs_fs_i.h, inode.c:
	Make hdr_layout per-inode (not per-file) so hdr_truncate() will work.

	* file.c, hfs.h, catalog.c, extent.c, balloc.c:
	hfs_extent_adj() now uses fork->lsize to determine the target file size.

Sun Sep 15 07:55:24 1996  Paul H. Hargrove  <[e-mail]>

	* README.sgml, trans.c:
	Prevent creation of files & directories with '\0' or ':' in their names.

	* string.c, hfs_fs.h, hfs.h, dir_dbl.c, dir_nat.c, dir_cap.c:
	With case=lower could have run off end of string.

Tue Sep 10 12:05:47 1996  Paul H. Hargrove  <[e-mail]>

	* inode.c:
	Small clean up of HFS_FIL_LOCK handling.

	* inode.c:
	Fix notify_change() not to accidentally make metadata executable.

	* hfs_fs.h:
	AppleSingle files should have HFS_ITYPE_NORM.

	* inode.c:
	Return to old behavior where MdDat = i_mtime.

	* dir_dbl.c:
	Fix serious bug in hfs_dbl_readdir() that would lock-up access to a
	directory if one tried to write to a directory they had previously read.

	* file.c:
	Fix hfs_do_write() to adjust the fork's 'lsize' if it changed.

	* inode.c, file_cap.c:
	Allow truncate() to be called even on metadata.
	Any size changes will last only until the next iput() of the inode.
	Truncating a header file doesn't yet truncate the resource fork.

	* inode.c:
	Allow chmod() on a directory if it doesn't actually change i_mode.

	* hfs_fs.h, trans.c, super.c:
	Rename hfs_cap2mac() to hfs_colon2mac().
	Rename hfs_apl2mac() to hfs_prcnt2mac().

	* file_hdr.c:
	Move header construction out of hdr_read() to create hdr_build_meta().

	* hfs.h:
	Add byte-order independent conversions: U32->U16, U32->U8 and U16->U8.

	* file.c, file_cap.c, hfs_fs.h:
	Rename fix_perms() to hfs_file_fix_mode() and
	move it from file_cap.c to file.c.

	* README.sgml, super.c:
	Make the default for the names mount option vary with the fork option.

	* file_cap.c:
	The umask was applied incorrectly in fix_perms().

Mon Sep  9 13:11:28 1996  Paul H. Hargrove  <[e-mail]>

	* README.sgml:
	Note that it compiles on m68k machines, but needs more testing.

	* hfs_sysdep.h, Makefile:
	Changes to compile unmodified on m68k (and possibly other machines).

	* dir_cap.c:
	hfs_cap_readdir() was mistakenly producing .rootinfo entries for
	the .finderinfo and .resource subdirectories of the root directory.

	* inode.c:
	A directory's i_size was too small by 1 under CAP, so hfs_cap_readdir()
	would omit the last directory entry.  i_nlink was also too large by 1.

Sun Sep  8 12:56:06 1996  Paul H. Hargrove  <[e-mail]>

	* file_hdr.c:
	Rewrite hdr_read() to be more efficient and to deal correctly with
	descriptors having lengths that differ from the actual size of the data.

	* file_cap.c:
	Add write support for CAP finderinfo files!!

	* super.c, inode.c, hfs_fs.h, hfs_fs_i.h, hfs_fs_sb.h, file_dbl.c,
	  file_nat.c, file_hdr.c, file.c, file_cap.c, Makefile, dir.c:
	Generate metadata (header files and CAP finderinfo files) on-the-fly.
	The files file_{dbl,nat}.c are merged into file_hdr.c as a result.

Sat Sep  7 08:09:24 1996  Paul H. Hargrove  <[e-mail]>

	* README.sgml:
	Fix silly grammatical error.
