	behavior.

2009-12-28  Andreas Gruenbacher  <agruen@suse.de>

	* tests/create-delete: Clean up a syntactic glitch.

	* src/pch.c: When the input files to diff have CRLF line endings, the
	'<' and '>' lines of normal-style diffs will have CRLF endings even
	when the patch itself has not been CRLF mangled.  Do not assume a
	mangled patch in this case.
	* tests/crlf-handling: Update test case to cover this case.

	* configure.ac (gl_FUNC_STRNDUP, gl_FUNC_STRNLEN): Add here.
	* gl/m4/strndup.m4 (gl_HEADER_STRING_H_DEFAULTS): Don't use gnulib's
	strings.h replacement for now, it is too complicated to add right now.
	* gl/lib/xstrndup.c: Instead of using gl_HEADER_STRING_H_DEFAULTS,
	declare strndup here on systems which don't have it.
	* gl/lib/strndup.c: Instead of using gl_HEADER_STRING_H_DEFAULTS,
	declare strnlen here on systems which don't have it.
	* gl/lib/strnlen.c: Import from gnulib.

	* Makefile.in (getopt.h, GETOPT_H): Generate getopt.h in the top-level
	directory if needed.
	(stdbool.h, STDBOOL_H): Likewise -- this should fix stdbool.h
	generation on platforms which don't provide this header.
	(argmatch.$(OBJEXT)): Add missing $(STDBOOL_H) dependency.

	* install-sh: Make executable.

2009-12-22  Andreas Gruenbacher  <agruen@suse.de>

	* src/version.c (copyright_string): Add year 2009.

	* src/pch.c (intuit_diff_type): Add some clarifying comments.

	* src/pch.c (intuit_diff_type): Fix regression introduced after patch
	2.5.9: when none of the filenames in the old, new, and index headers
	exists, patch chose the wrong filename (bug 28367).
	(maybe_reverse): Return if the patch looks reversed, not if this
	function toggled the reverse flag.
	* tests/filename-choice: New test case.
	* Makefile.in (TESTS): Add test case.

2009-11-24  Bert Wesarg <bert.wesarg@googlemail.com>

	* configure.ac: It looks like the . command does not pass the
	arguments to the update-version.sh script [on some platforms].  Invoke
	with sh instead.

	* Makefile.in (LIBSRCS, LIBHDRS, LIBM4FILES): Add the gnulib which
	were imported on 2009-06-05 here as well.

	* src/partime.c (main): Try to preserve the owning group of patched

2009-06-15  Andreas Gruenbacher  <agruen@suse.de>

	* src/util.c (move_file): Don't fail when removing nonexistent
	files: this condition is already checked in maybe_reverse().

2009-06-05  Andreas Gruenbacher  <agruen@suse.de>

	* gl/lib/getopt_int.h, gl/lib/strndup.c, gl/m4/strndup.m4: Add
	some missing gnulib files.
	* Makefile.in (GETOPT_H): Include subdirectory (gl/lib/) when
	using the gnulib version.

	* src/patch.c: When sending output to stdout, use dup2 to redirect
	messages to stderr; simply assigning stderr to stdout doesn't work on
	some platforms.
	* gl/lib/dup2.c, gl/m4/dup2.m4: Import from gnulib.

	* gl/lib/rename.c, gl/m4/rename.m4: Import from gnulib for platforms
	like Mingw.

	* src/pch.c (maybe_reverse): New function.
	(intuit_diff_type): Move the check back here from
	there_is_another_patch(), but compute it using maybe_reverse().  If
	an input file name has been specified, do this check here as well.
	* src/patch.c (main): Only set outname if we are not skipping the
	patch.
	* src/inp.c (get_input_file): We may get here without a file to read
	as well now; don't abort in this case.
	* tests/create-delete: Add test cases covering the previously-broken
	code paths.

	* Makefile.in (MISC): Add config.guess and config.sub.

	* src/partime.c (parse_pattern_letter): Fix for timestamps with
	seconds > 59.5 from Christian Franke.

2009-04-05  Andreas Gruenbacher  <agruen@suse.de>

	* util.c (create_backup): We also need to create base directories
	with a --prefix without slashes and a filename with slashes. A
	--suffix cannot contain slashes, though.

	files into src/.
	* Makefile.in, tests/test-lib.sh, configure.ac, autogen.sh: Update
	accordingly.
	* m4/st_mtim.m4: Remove (obsolete since 2009-03-28).

	gl/m4/unlocked-io.m4, gl/m4/utimbuf.m4, gl/m4/xalloc.m4: Likewise.
	* install-sh, mkinstalldirs: Likewise.
	* gl/lib/stdbool.hin: Renamed from gl/lib/stdbool_.h.
	* gl/lib/getopt.h: Removed (should be generated).
	* gl/lib/addext.c: Removed from Gnulib.

	Replace memory_fatal() with xalloc_die().  The FILESYSTEM_PREFIX_LEN()
	macro has been renamed to FILE_SYSTEM_PREFIX_LEN().
	* src/patch.c (main): Remove xalloc_fail_func (replaced by
	xalloc_die()).  Work around the missing addext() with
	find_backup_file_name() plus hacks.
	* src/util.c (create_backup, version_controller): The new versions of
	base_name() and dir_name() return malloc'ed buffers.  Adapt.
	* src/util.h: Replace memory_fatal() with xalloc_die().
	* src/pch.c: Don't leak memory with strlen (base_name (...)).

	* src/util.c (create_file): Add to_dir_known_to_exist argument and
	try to create parent directories when set and the create failed with
	ENOENT.
	(copy_file, create_backup_copy): Pass the new to_dir_known_to_exist
	argument through.
	(create_backup): Don't assume the target directory exists when making
	a backup copy.
	* src/util.h (create_file, copy_file): Change the declarations.
	* src/patch.c, src/pch.c, src/inp.c: In the calls to create_file() and
	copy_file(), assume the parent directory exists.
	* tests/unmodified-files: Test the create_backup() fix.

	* src/util.c (create_backup): The new dir_name() and base_name()
	functions are really counter productive.  Remove them and the bugs
	that keepeing them here as introduced.
	* tests/backup-prefix-suffix: Add more regression tests.

	* src/patch.c (locate_hunk): Revert to the original asymmetric hunk
	behavior (but only anchor hunks starting at line 0 to the start of the
	file): there is not enough reason to change the historic behavior.
	* src/merge.c (locate_merge): Add similar asymmetric hunk check here.
	* tests/asymmetric-hunks: Update accordingly.
	* patch.man: Document the asymmetric hunk behavior.
	* NEWS: Update.

	Copyright notice updates.
	* README, AUTHORS: Updates.

	debug output.
	* merge.c (merge_hunk): Likewise.
	(locate_merge): Add a note about the algorithm's requirements.
	* util.c (create_backup): Split from move_file.  New LEAVE_ORIGINAL
	argument for copying instead of renaming.  Don't fail when rename
	fails with errno == EXDEV; copy and unlink in that case instead.
	(copy_file): Add debug message.
	* util.h: Move including <utime.h> etc. here from patch.c.
	(create_backup): Declare.
	* patch.c (main): Create backup files even for files which did not
	actually change; some users of patch rely on the presence of backup
	files when patch says "patching file".
	* tests/unmodified-files: Test the patch.c change.  (The EXDEV fix in
	create_mackup() was tested manually.)
	* util.c (copy_to_fd, ask): The read() return type is ssize_t.

2009-04-03  Andreas Gruenbacher  <agruen@suse.de>

	* patch.man: Document the -m or --merge option.  Some minor other
	changes.
	* NEWS: Document the asymmetric hunk behavior and the -m or --merge
	option.
	* merge.c (locate_merge): Include the number of changes in the debug
	message.
	(print_linerange): New function.
	(merge_result): No longer print line offsets: without exact matches,
	line numbers are less meaningful.  Output the entire messages here.
	(merge_hunk): Be silent when merging exact matches unless in
	--verbose mode.
	* tests/merge: Add another interesting test case.

	* tests/test-lib.sh: Add have_ed function for checking if ed is
	available.
	* tests/crlf-handling, tests/need-filename: Check for ed and skip the
	ed related tests if we don't have it.
	* tests/merge: Use sed instead of ed: sed is more readily available.

	* patch.c (locate_hunk): If a hunk starts at a line > 1, it obviously
	is not from the start of the file.
	* tests/asymmetric-hunks: Add tests for all possible cases.

2009-04-02  Andreas Gruenbacher  <agruen@suse.de>

	* patch.c (locate_hunk): Revert the assymmetric hunk fix from
	2009-03-29.  Instead, allow such hunks to apply only when no
	more context remains.

	* patch.c (main): Restructure to get rid of some code duplication.
	(copy_till, similar): Export these functions.
	* common.h (struct outstate, in_offset, out_offset,
	last_frozen_line): Move here from patch.c.
	(apply_hunk, copy_till, similar): Declare here.

	Simple merge support:
	* configure.ac (ENABLE_MERGE): New --disable-merge option.
	* patch.c (merge): New variable.
	(main): New -m and --merge options.  When in merge mode, don't try
	to reverse patches, and don't try to apply with fuzz.
	* common.h (merge_hunk): Declare function.
	* merge.c: New file containing all the merge code.
	* tests/merge: New test case.
	* Makefile.in (SRCS): Add merge.c.
	(OBJS): Add merge.$(OBJEXT) when merge support is enabled.
	(TESTS): Add test case.
	(COMPILE): Define ENABLE_MERGE when merge support is enabled.

	Locate hunks to merge more intelligently:
	* bestmatch.h: Shortest Edit Sequence algorithm.
	* merge.c (locate_merge, count_fuzz_lines): New functions.
	(merge_hunk): Replace simple guessing with locate_merge().
	* Makefile.in (HDRS): Add bestmatch.h.
	* tests/merge: Only minor improvements up to now.

	* diffseq.h: New file (Gnulib compareseq algorithm).
	* minmax.h: New file (Gnulib MIN and MAX macros).
	* Makefile.in (HDRS): Add diffseq.h and minmax.h.

	* COPYING: Update to GPL version 3 because of diffseq.h.

	* diffseq.h: When an EQUAL_IDX macro is defined, use that instead
	of EQUAL.  This macro takes vector indexes instead of elements as
	arguments.

	Better merge support:
	* patch.c, common.h (apply_hunk): Make static again.
	* merge.c (compute_changes): New function for computing the
	difference between lines in a hunk and lines in the input file.
	(merge_result): We may have more than one result per hunk now.
	(merge_hunk): Merge the hunk with the compute_changes() result.
	* tests/merge: Better results now.

	* merge.c: Add license header.

	* merge.c (locate_merge): The number of changes allowed permits a
	higher maximum merge position (max_where).
	* tests/merge: Add a test for this case.

	* merge.c (merge_hunk): Add two missing checks that were leading into
	failed assertions.
	* tests/merge: Add test cases for each of these checks.

	* Makefile.in (install, uninstall): DESTDIR specifies a prefix to
	the root directory to install into.
	(installdirs): Merge with install.

2009-04-01  Andreas Gruenbacher  <agruen@suse.de>

	* tests/test-lib.sh: When $GDB is set, run patch in gdbserver
	for debugging.
	* pch.c (another_hunk): Make the debug output easier to read.

2009-03-31  Andreas Gruenbacher  <agruen@suse.de>

	* patch.c: Split last_offset into in_offset and out_offset and
	count line numbers properly.
	* tests/line-numbers: Without the fixes, this test case goes
	horribly wrong.
	* Makefile.in (TESTS): Add test case.

2009-03-30  Jim Meyering  <meyering@redhat.com>

	tests: accommodate ls' "alternate access control method" indicator
	ls can output an additional byte after a file's permissions string,
	e.g., rather than "rwxr--r-- ..." it can output "rwxr--r--+ ..."
	or "rwxr--r--. ..." to indicate the presence of an ACL.
	* tests/create-delete: Adjust sed filter to accommodate that.
	* tests/preserve-mode-and-timestamp: Likewise.

2009-03-30  Andreas Gruenbacher  <agruen@suse.de>

	* tests/test-lib.sh: Unset environment variables that influence
	the behavior of patch.
	* util.c (move_file): Add debug message when files have been seen
	already.  Fix leftover "empty uneadable" debug message.

	* patch.c (main): Print newline earlier.
	* util.c (copy_file): Add debug message.

2009-03-29  Andreas Gruenbacher  <agruen@suse.de>

	* patch.c (locate_hunk): Hunks that have fewer or more lines of
	context at the beginning than at the end can match anywhere; the
	assumption that this can only occur at the beginning or end of the
	file is wrong. Remove those checks.
	* tests/asymmetric-hunks: New test case.
	* Makefile.in (TESTS): Add test case.

	* util.c (move_file): Create backup files of nonexisting files with
	the default mode instead of mode 0: files with mode 0 cause too many
	problems with applications which do not expect unreadable files.
	* tests/create-delete: Test for this.

	* Makefile.in (BROKEN_TESTS): Test cases which fail.

2009-03-28  Andreas Gruenbacher  <agruen@suse.de>

	* pch.c (intuit_diff_type): Rename need_filename argument to
	need_header.  Omit superfluous "missing header" warnings.

	When remembering files including timestamps, we need to update the
	timestamps after appending to a file.  This causes problems on some
	systems where the timestamps returned by fstat() after appending are
	not up to date, yes.  We only remember timestamps as a compatibility
	hack with non-POSIX systems that do not have unique inode numbers;
	drop this hack instead.
	* timespec.h, m4/timespec.m4: Remove.
	* util.c: Remove timespec.h and all uses of struct timespec.
	(append_to_file): Remove REMEMBER argument; no need to update known
	files anymore.
	* util.h (append_to_file): Update definition.
	* Makefile.in: Remove timespec.h and m4/timespec.m4.

	* common.h (origsuff): New variable.
	* patch.c (main): Remember when -z was used.
	* util.c (contains_slash): New function.
	(move_file): Enforce simple backup mode and compute the backup file
	name here if -B, -Y, or -z is used.  Fix the case where -B or -Y is
	combined with -z.
	* patch.man: Document this change.
	* tests/backup-prefix-suffix: New test case.
	* Makefile.in (TESTS): Add test case.

	* tests/munged-context-format: New test case.
	* Makefile.in (TESTS): Add test case.

	* util.c (vsay): New function for use in say(), etc.
	(ok_to_reverse): Use vsay() here instead of fprintf() to ensure
	flushing.

	* pch.c (there_is_another_patch): Move the "patch would create" test
	here from intuit_diff_type() after asking for the filename to patch.
	* inp.c (get_input_file): No need to report when the file is missing;
	this is done in there_is_another_patch() already.
	* patch.c (main): No need to report when a patch attempts to create
	an exiting file, either.

2009-03-25  Andreas Gruenbacher  <agruen@suse.de>

	* patch.c (main): Avoid replacing files when nothing has changed.
	* tests/unmodified-files: New test case.
	* Makefile.in (TESTS): Add test case.

	* patch.c (main): New apply_empty_patch variable. When applying an
	empty patch to a file and -o is given, copy the input file to the
	output file.

2009-03-24  Andreas Gruenbacher  <agruen@suse.de>

	* patch.c (abort_hunk_unified, abort_hunk_context): Preserve
	Index lines in reject files as well.
	* tests/reject-format: Test this change.

	* configure.ac (TEST_SHELL): New substitution.
	* Makefile.in (TEST_SHELL): New variable.
	(HAVE__BOOL): New variable.
	(hash.$(OBJEXT)): Add $(STDBOOL_H) dependency.
	* tests/test-lib.sh: Use expr for arithmetic operations. Check for
	working "echo -n" and BASH_LINENO.  Replace printf with echo.
	* tests/preserve-mode-and-timestamp: Ignore leading "+" in ls output.
	* tests: Remove !shebang line from tests and make them non-executable.
	Replace printf with echo.

2009-03-23  Andreas Gruenbacher  <agruen@suse.de>

	* patch.c (intuit_diff_type): When looking for an ed or normal
	patch, don't look for filename headers.  (Those formats don't
	have any.)
	* pch.c (there_is_another_patch): Don't suggest to use -p with
	normal format diffs for the same reason.

2009-03-22  Andreas Gruenbacher  <agruen@suse.de>

	* NEWS: Update for alpha release.

	* patch.c (main): Always initialize the known files table.

	* util.c (file_already_seen): Export.
	(move_file): Remember all files, not only backup files.
	(append_to_file): When asked to remember a file, remember
	the state *after* appending. (The timestamps will change!)
	* tests/remember-reject-files: New test case.
	* Makefile.in (TESTS): Add test case.

	* common.h (no_strip_trailing_cr): New variable.
	* patch.c: Use no_strip_trailing_cr.  Option --binary no longer
	a no-op on POSIX systems.
