Wed Jul 19 16:01:22 2000  Glenn Fowler <gsf@research.att.com>

	* diff3 : call execvp() instead of execve()

Sat Oct  1 05:24:19 1994  Paul Eggert  <eggert@twinsun.com>

	(AC_CHECK_HEADERS): Remove sys/wait.h.
	(AC_CHECK_FUNCS): Add tmpnam.
	* system.h (<sys/wait.h>, WEXITSTATUS): Use simpler scheme
	now that HAVE_SYS_WAIT_H is not set on hosts
	that are incompatible with Posix applications.

	* util.c (dir_file_pathname): Use filename_lastdirchar not strrchr.
	* sdiff.c (expand_name): Likewise.
	(private_tempnam): Use tmpnam if HAVE_TMPNAM; this simplifies porting.
	(exists, letters): Omit if HAVE_TMPNAM.

	* diff3.c (read_diff): If STAT_BLOCKSIZE yields zero,
	adjust it to a more reasonable value.

Sat Sep 24 20:36:40 1994  Paul Eggert  <eggert@twinsun.com>

	* sdiff.c (exists, private_tempname): Adopt latest GNU libc algorithm.
	(private_tempnam): Specialize for sdiff to avoid portability problems.

Thu Sep 22 16:47:00 1994  Paul Eggert  <eggert@twinsun.com>

	* configure.in (AC_ARG_PROGRAM): Added.
	(AC_OUTPUT): Add [date > stamp-h].

	NULL_DEVICE, PR_PROGRAM, PROGRAMS): New variables.
	(check, stamp-h.in, cmp.o, util.o): New targets.
	(edit_program_name): New variable; replaces old binprefix method.
	(install, uninstall): Use it.
	(binprefix): Removed.
	(distfiles): Add stamp-h.in.

	Use NULL_DEVICE instead of "/dev/null".
	(cmp): Use %lu instead of %ld when it is more likely to be right.

	* diff.h (PR_FILE_NAME): Rename to PR_PROGRAM and move to Makefile.in,
	util.c.

	* diff3.c (main): Give proper diagnostic if too many labels were given.
	(read_diff): Use SYSTEM_QUOTE_ARG.

	(private_tempnam): Don't access "/tmp" directly; use PVT_tmpdir.

Tue Sep 13 18:46:43 1994  Paul Eggert  <eggert@twinsun.com>

	* configure.in (AC_FUNC_MEMCHR): Remove.  Autoconf didn't adopt this,
	since we need not worry about an old experimental library
	where memchr didn't work.
	(AC_FUNC_MEMCMP): Not needed, since we only test for equality.
	(AC_REPLACE_FUNCS): Add test for memchr.
	(AC_CHECK_FUNCS): Check for memchr, not memcpy, since it'll be cached.
	(AC_CHECK_HEADERS): Add string.h; regex.c uses on some old hosts.

	* system.h (memcmp): Define in terms of bcmp.
	Use HAVE_MEMCHR to test for all mem* routines.

	* Makefile.in (srcs): Remove memcmp.c.
	We use bcmp if memcmp doesn't work, since we only test for equality.

Mon Sep 12 15:52:22 1994  Paul Eggert  <eggert@twinsun.com>

	* configure.in (AC_CONFIG_HEADER): Rename config.h.in to config.hin.

	(srcs): Add memcmp.c.
	(distfiles): Rename config.h.in->config.hin, install.sh->install-sh.
	(Makefile, config.h, config.hin, config.status): Rework for
	compatibility with Autoconf 2.
	* io.c (binary_file_p): Assume non-broken memchr.
	* memchr.c: Assume compiler understands void *; otherwise
	we don't match GCC's internal declaration of memchr.
	* system.h: Use more modern autoconf approach to standard C headers.
	* version.c: Include <config.h>, not "config.h".

	* diff.c, diff.h (ignore_some_line_changes):
	New variable; replaces `length_varies'.
	(line_end_char): Replace with '; it wasn't being used consistently.

	* io.c (find_and_hash_each_line): Fix inconsistencies with -b -w -i and
	incomplete lines.  Put incomplete lines into their own bucket.
	This means line_cmp no longer needs line length arguments,
	and equivalence classes' line lengths no longer need to include 
	Invoke line_cmp only if ignore_some_line_changes.
	(prepare_text_end): -B no longer ignores missing newlines.
	(read_files): Allocate another bucket for incomplete lines.

	* util.c (line_cmp): Now takes just two arguments.  No longer
	optimizes for common case of exact equality; the caller does that
	optimization now.  The caller is changed accordingly.
	Optimize for the common case of mostly equality.
	Use isupper+tolower instead of islower+toupper, for consistency.

	* waitpid.c (waitpid): Fix typo with internal scoping.

Thu Sep  8 08:23:15 1994  Paul Eggert  <eggert@twinsun.com>

	* configure.in: Revamp for Autoconf 2.
	* memchr.c, waitpid.c: New source files for substitute functions.

	(srcs): Add memchr.c, waitpid.c.
	(distfiles): Add install.sh, memchr.c, waitpid.c, install.sh.
	* system.h: Use Autoconf 2 style HAVE_DIRENT_H etc. macros for dirs.
	* dir.c (dir_sort): Prefer NAMLEN (p) to strlen (p->d_name).
	Change VOID_CLOSEDIR to CLOSEDIR_VOID for Autoconf 2.
	* sdiff.c, util.c (memchr, waitpid): Remove; use new substitutes.
	* diff3.c (read_diff): Use new waitpid substitute.

	* cmp.c, diff.c, diff3.c, sdiff.c (check_stdout, try_help): New fns.
	(usage): Just print more detailed usage message; let caller exit.
	* diff.c (option_help): New variable.

	make sure SIGCHLD isn't ignored.

	* diff3.c (DIFF_CHUNK_SIZE): Removed.  Get size from STAT_BLOCKSIZE.
	(INT_STRLEN_BOUND): New macro.

	* ifdef.c (format_group, groups_letter_value):
	Use * instead of [] in prototypes.

	* system.h: Include <sys/file.h> only if HAVE_SYS_FILE_H.
	(S_IXGRP, S_IXOTH, S_IXUSR): Remove unused macros.

	* util.c (begin_output): Check fdopen result.

	The following changes simplify porting to non-Posix environments.
	* cmp.c, diff.c, diff3.c, sdiff.c, (main): Call initialize_main first.
	* diff.c (binary_I_O): New variable for --binary option.
	(main, usage, compare_files): Support --binary option.

	diff_dirs): Use filename_cmp to compare file names.
	Use same_file to determine whether two files are the same.
	* context.c (print_context_label): Check whether ctime yields 0.
	* diff3.c (read_diff), sdiff.c (cleanup, main, waitpid),
	util.c (begin_output): Use popen+pclose if !HAVE_FORK.

	initialize_main O_BINARY, same_file): New macros.

Fri Jun 17 11:23:53 1994  David J. MacKenzie  (djm@geech.gnu.ai.mit.edu)

	* Makefile.in (info, dvi, diff.dvi): New targets.
	(clean): Remove TeX output files.

Fri Jun 17 05:37:52 1994  Paul Eggert  (eggert@twinsun.com)

	* cmp.c, io.c (word): Change from typedef to #define, to avoid
	collision with Unicos 8.0 <sys/types.h>, which also typedefs `word'.

Thu Apr 15 00:53:01 1994  Paul Eggert  (eggert@twinsun.com)

	* diff3.c (scan_diff_line), util.c (print_number_range): Don't
	rely on promotion to make the old-style parameter type agree
	with the prototype parameter type; this doesn't work on

	producing suboptimal output for large inputs with many differences.
	(diff_2_files): Initialize it.
	(struct partition): New type.
	(SNAKE_LIMIT): New macro; merely documents already-used number 20.

	* diff3.c, sdiff.c, util.c (xmalloc, xrealloc): Cast malloc, realloc
	to (VOID *) to suppress bogus warnings on some nonstandard hosts.

	* sdiff.c, util.c (memchr): Make first arg char const *
	to match standard.

	* system.h (malloc, realloc): Declare only if !HAVE_STDLIB_H.
	(memchr): Declare only if !HAVE_MEMCHR.  These changes are
	needed to keep some nonstandard hosts happy.

	* xmalloc.c: Include <sys/types.h> always; some nonstandard hosts
	need it for size_t even if STDC_HEADERS.

Sat Sep 18 01:33:07 1993  Paul Eggert  (eggert@twinsun.com)

	* configure.in (AC_STAT_MACROS_BROKEN): Add.
	* system.h (S_IS{BLK,CHR,DIR,FIFO,REG,SOCK}): Fix defns if
	STAT_MACROS_BROKEN.

	* Makefile.in (diff3, sdiff, cmp): Do not link $(ALLOCA).

	* analyze.c (discard_confusing_lines): Make defn static, like decl.
	* sdiff.c (xmalloc): Likewise.

	* ifdef.c (format_group): Ensure isdigit argument isn't < 0.

	* side.c (print_half_line): Use isprint, since some hosts lack isgraph.
	* util.c (output_1_line): Likewise.  Ensure its argument isn't < 0.
	(xmalloc, xrealloc): Remove needless casts.

	* system.h (volatile, const):
	Define these before including any system headers,
	so that they're used consistently in all system includes.
	(getenv, malloc, realloc): Declare even if HAVE_STDLIB_H, since some
	<stdlib.h>s don't declare them.
	(memchr): Likewise for <string.h>.

	* cmp.c, diff3.c, diff.h, sdiff.c: Include "system.h" first.
	* diff.c: Remove redundant "system.h" inclusion.

	* diff3.c (xmalloc): Now static.
	(xmalloc, realloc): Remove needless casts.

Wed Sep 14 07:14:15 1993  Paul Eggert  (eggert@twinsun.com)

	* Version 2.4 released.

	* ifdef.c (scan_char_literal): New function, for new %c'x' and
	%c'\ooo' format specs.
	(format_group, print_ifdef_lines): Use it.  Remove %0 format spec.

	* cmp.c (cmp): Don't try to read past end of file; this doesn't
	work on ttys.

	* system.h, version.c: #include <config.h>, not "config.h", to allow
	configuring in a separate directory when the source directory has
	already been configured.
	* Makefile.in (COMPILE): New defn, with proper -I options so that
	`#include <config.h>' works.
	(.c.o, diff3.o, sdiff.o): Use it.

Mon Sep 13 06:45:43 1993  Paul Eggert  (eggert@twinsun.com)

	* diff.c (main, longopts): Add --line-format=FORMAT option.
	(specify_format): Args no longer const pointers.  All callers changed.

	* ifdef.c: Add support for %?c, %(A=B?T:E), PRINTF_SPECn formats.
	(struct group): New struct.
	(print_ifdef_lines): Use it to simplify argument passing.
	Remove the convention that last arg -1 signifies that the lines
	from file 2 are the same as the lines from file 1; this
	convention no longer works, now that line numbers might be
	printed out, since the line numbers may differ.
	Add first FILE * argument to output to.  All callers changed.
	Use a faster test for the single-fwrite optimization.
	(format_group, scan_printf_spec, groups_letter_value): New functions.

	* diff.h (group_format, line_format): No longer const pointers.
	(format_ifdef): 1st arg is no longer const pointer.

	Include only if HAVE_LIMITS_H etc.

	* system.h (memcmp, memcpy, strchr, strrchr, struct dirent): Prefer
	these standard names to the traditional names (bcmp, bcpy, index,
	rindex, struct direct).  All callers changed.

	* system.h (PARAMS, VOID):
	Define earlier so that malloc decl can use VOID.
	(STAT_BLOCKSIZE): Simplify ersatz defn; just use 8K.

Fri Sep  3 00:21:02 1993  Paul Eggert  (eggert@twinsun.com)

	* diff.c (compare_files): Two files with the same name must be
	the same file; avoid a needless `stat' in that case.

Fri Aug 27 06:59:03 1993  Paul Eggert  (eggert@twinsun.com)

	* Pervasive changes for portability to 64-bit hosts:
	Add prototypes to function declarations.
	Use size_t, not int, when needed.

	* Other pervasive changes:
	Use `const' more often.
	Use STD{IN,OUT,ERR}_FILENO instead of [012].
	Use 0, not NULL, for portability to broken hosts.

	* Makefile.in: (srcs, objs, distfiles, cmp): New files cmpbuf.[ch].
	(distfiles): New files config.h.in, mkinstalldirs.
	(.c.o): Add -DHAVE_CONFIG_H.

	* analyze.c: (diag): Pacify `gcc -Wall' with a useless assignment.
	(diff_2_files): Use l.c.m., not max, of files' buffer sizes.

	* cmp.c: Make globals static when possible.

	(file): Now a 2-element array; replaces `file1' and `file2'.
	(file_desc, buffer): Likewise, for file[12]_desc and buf[12].
	(main): Likewise, for stat_buf[12].  Index these variables with `i'.

	(ignore_initial): New var.
	(long_options): Now const.  Add `--ignore-initial'.
	(usage): Sort options and add `--ignore-initial'.
	(main, cmp): Add `--ignore-initial' support.

	(main): `cmp - -' now succeeds.
	When comparing standard input to a file, and using a shortcut (e.g.
	looking at file sizes or inode numbers), take the lseek offset into
	account before deciding whether the files are identical.
	Avoid mentioning `dev_t', `ino_t' for portability to nonstandard hosts.
	Use l.c.m. of files' buffer sizes, not 8 * 1024.
	ferror (stdout) does not imply errno has a useful value.
	If 2nd file is "-", treat it first, in case stdin is closed.

	(cmp): Always compute `char_number', `smaller' for speed and simplicity.
	Say `cmp: EOF on input', not `/usr/gnu/bin/cmp: EOF on input',
	as per Posix.2.

	(block_compare_and_count): Increment line_number argument.
	Remove end_char argument; it's always '.  All callers changed.
	Do not assume sizeof(long) == 4; this isn't true on some 64-bit hosts.
	(block_compare): Minimize differences with block_compare_and_count.

	(block_read): Coalesce `bp += nread's.

	(printc): Remove `FILE *' arg; output to stdout.  All callers changed.

	* configure.in: Configure HAVE_SIGACTION, RETSIGTYPE, HAVE_VPRINTF.
	Configure into config.h.

	* context.c (print_context_label):
	Standard input's st_mtime is no longer a special case
	here, since `compare_files' now sets it to the current time.

	* diff.c (usage): Sort options.
	(filetype): New function.
	(compare_files): Set stdin's st_mtime to be the current time.
	Leave its name "-" instead of changing it to "Standard Input";
	to test whether a file is stdin, we must compare its name to "-" instead
	of its desc to 0, since if it's closed other file descs may be 0.
	When comparing standard input to a file, and using a shortcut (e.g.
	looking at file sizes or inode numbers), take the lseek offset into
	account before deciding whether the files are identical.
	Pretend that nonexistent files have the same filetype as existing files.
	Rename `errorcount' to `failed', since it's boolean.
	In directory comparisons, if a file is neither a regular file nor a
	directory, just print its type and the other file's type.

	* diff.h (Is_space, textchar): Remove.
	(struct msg, msg_chain, msg_chain_end): Move to util.c.
	(VOID): Move to system.h.
	(line_cmp, version_string, change_letter, print_number_range,
	find_change): New decls.

	* diff.texi:
	whitespace -> white space.  It now stands for whatever isspace yields.
	Add --ignore-initial.

	* diff3.c (VOID): Move to system.h.
	(version_string): Now char[].
	(usage): Sort options.
	(process_diff): Pacify `gcc -Wall' with a useless assignment.
	(read_diff): pid is of type pid_t, not int.  Use waitpid if available.
	(output_diff3): Simplify test for ` No newline at end of file' message.

	* dir.c (struct dirdata): Rename `files' to `names' to avoid confusion
	with external struct file_data `files'.

	* io.c (line_cmp): Move declaration to diff.h.
	(textchar): Remove.
	(find_and_hash_each_line): Use locale's definition of white space
	instead of using one hardwired defn for -b and another for -w.

	* normal.c (change_letter, print_number_range, find_change):
	Move decls to diff.h.
	(print_normal_hunk): Now static.

	* sdiff.c (SEEK_SET): Move to system.h.
	(version_string): Now char[], not char*.
	(private_tempnam): Remove hardcoded limit on temporary file names.
	(exiterr, perror_fatal, main): When exiting because of a signal,
	exit with that signal's status.
	(lf_refill, main, skip_white, edit, interact): Check for signal.
	(ignore_SIGINT): Renamed from `ignore_signals'.
	(NUM_SIGS, initial_handler): New macros.
	(initial_action, signal_received, sigs_trapped): New vars.
	(catchsig, trapsigs): Use sigaction if possible, since this closes the
	windows of vulnerability that `signal' has.  Use RETSIGTYPE not void.
	When a signal comes in, just set a global variable; this is safer.
	(checksigs, untrapsig): New functions.
	(edit): Pacify `gcc -Wall' with a useless assignment.
	Respond to each empty line with help, not to every other empty line.
	(private_tempnam): Remove hardcoded limit on temporary file name length.
	Don't assume sizeof (pid_t) <= sizeof (int).

	* system.h: (S_IXOTH, S_IXGRP, S_IXUSR,
	SEEK_SET, SEEK_CUR,
	STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO):
	New macros, if system doesn't define them.
	(volatile): Don't define if already defined.
	(PARAMS): New macro.
	(VOID): Move here from diff.h.

	* util.c (struct msg, msg_chain, msg_chain_end): Moved here from diff.h.
	(message5): New function.
	(pr_pid): New var.
	(begin_output): Allocate `name' more precisely.
	Put child pid into pr_pid, so that we can wait for it later.
	Don't check execl's return value, since any return must be an error.
	(finish_output): Detect and report output errors.
	Use waitpid if available.  Check pr exit status.
	(line_cmp): Use locale's definition of white space
	instead of using one hardwired defn for -b and another for -w.
	(analyze_cmp): Avoid double negation with `! nontrivial'.
	Pacify `gcc -Wall' be rewriting for-loop into do-while-loop.
	(dir_file_pathname): New function.

	* version.c (version_string): Now char[], not char*.

	* Makefile.in (dist): Replace `if [ ! TEST ]; then ACTION; fi'
	with `[ TEST ] || ACTION || exit' so that the containing for-loop exits
	with proper status for `make'.

Thu Jul  8 19:47:22 1993  David J. MacKenzie  (djm@goldman.gnu.ai.mit.edu)

	* Makefile.in (installdirs): New target.
	(install): Use it.
	(Makefile, config.status, configure): New targets.

	* analyze.c, diff3.c, sdiff.c, util.c: Don't assume NULL is defined
	properly.

Tue May 25 14:54:05 1993  Paul Eggert  (eggert@twinsun.com)

	* analyze.c (diff_2_files):  With -q, do not report that files differ
	if all their differences are ignored.
	(briefly_report): New function.
	* diff.h (ignore_some_changes): New variable.
	* diff.c (compare_files): Don't use the file size shortcut if
	ignore_some_changes is nonzero, since the file size may differ
	merely due to ignored changes.
	(main):  Set ignore_some_changes if we might ignore some changes.
	Remove unsystematic assignment of 0 to static vars.
	* io.c (read_files): New argument PRETEND_BINARY says whether to
	pretend the files are binary.

	* diff3.c (tab_align_flag): New variable, for new -T option.
	(main, usage, output_diff3): Add support for -T.

	* dir.c (dir_sort): Always init `data' to avoid GCC warning.

Sat May 22 15:35:02 1993  Paul Eggert  (eggert@twinsun.com)

	* Makefile.in (dist): Change name of package from diff to diffutils.
	Don't bother to build .Z dist; .z suffices.

Fri May 21 16:35:22 1993  Paul Eggert  (eggert@twinsun.com)

	* diff.c: Include "system.h" to get memchr declaration.
	* system.h (memchr): Declare if !HAVE_MEMCHR, not if

	* system.h [HAVE_STRING_H || STDC_HEADERS] (bcopy, bcmp, bzero):
	Don't define if already defined.

Fri Mar  5 00:20:16 1993  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* diff.c (main): Use NULL in arg to compare_files.

Thu Feb 25 15:26:01 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* system.h: Declare memchr #if !HAVE_MEMCHR && !STDC_HEADERS,
	not #if !HAVE_MEMCHR || !STDC_HEADERS.

Mon Feb 22 15:04:46 1993  Richard Stallman  (rms@geech.gnu.ai.mit.edu)

	* io.c (find_identical_ends): Move complicated arg outside GUESS_LINES.

Mon Feb 22 12:56:12 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

Tue Feb  9 03:53:22 1993  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* Makefile.in (.c.o, diff3.o, sdiff.o): Put $(CFLAGS) last.

Wed Feb  3 15:42:10 1993  David J. MacKenzie  (djm@goldman.gnu.ai.mit.edu)

	* system.h: Don't #define const; let configure do it.

	* Version 2.1 released.

	* Makefile.in (dist): Survive ln failures.  Create .tar.z

	* Makefile.in: Note change from USG to HAVE_STRING_H.

Mon Nov 23 18:44:00 1992  Paul Eggert  (eggert@twinsun.com)

	* io.c (find_and_hash_each_line): When running out of lines,
	double the number of allocated lines, instead of just doubling
	that number minus the prefix lines.  This is more likely to
	avoid the need for further memory allocation.

Wed Nov 18 20:40:28 1992  Paul Eggert  (eggert@twinsun.com)

	* dir.c (dir_sort): Plug memory leak: space holding directory
	contents was not being reclaimed.  Get directory size from
	struct file_data for initial guess at memory needed.
	Detect errors when reading and closing directory.
	(diff_dirs): Pass struct file_data to dir_sort.  Finish plugging leak.
	* diff.c (compare_files): Pass struct file_data to diff_dirs.

	* io.c (find_and_hash_each_line): Don't assume alloc_lines is
	nonzero when allocating more lines.

	* diff3.c (usage): Add third --label option in example.

	* util.c (analyze_hunk): Fix test for ignoring blank lines.

	* configure.in, system.h: Avoid USG; use HAVE_TIME_H etc. instead.

Mon Nov  9 05:13:25 1992  Paul Eggert  (eggert@twinsun.com)

	* diff3.c (main, usage): Add -A or --show-all.
	-m now defaults to -A, not -E.  Allow up to three -L options.
	(output_diff3_edscript, output_diff3_merge):
	Remove spurious differences between these two functions.
	Output ||||||| for -A.  Distinguish between conflicts and overlaps.
	(dotlines, undotlines): New functions that output `Ns', not `N,Ns'.
	(output_diff3_edscript, output_diff3_merge): Use them.

	* io.c (find_identical_ends): shift_boundaries needs an extra
	identical line at the end, not at the beginning.

	* sdiff.c (edit): execvp wants char **, not const char **.

Mon Oct 19 04:39:32 1992  Paul Eggert  (eggert@twinsun.com)

	* context.c (print_context_script, find_function): Context
	line numbers start with - file->prefix_lines, not 0.

	* io.c (binary_file_p): Undo last change; it was a library bug.

Sun Oct 18 00:17:29 1992  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* io.c (binary_file_p): Consider empty file as non-binary.

Mon Oct  5 05:18:46 1992  Paul Eggert  (eggert@twinsun.com)

	* diff3.c (main, make_3way_diff, using_to_diff3_block): Don't
	report bogus differences (for one of -mexEX3) just because the
	file0-file1 diffs don't line up with the file0-file2 diffs.
	(This is entirely possible since we don't use diff's -n
	option.)  Always compare file1 to file2, so that diff3 sees
	those changes directly.  Typically, file2 is now the common
	file, not file0.
	(output_diff3_merge): The input file is file 0, not the common file.

	(FC, FO): New macros; they replace FILE1, FILE0 for two-way diffs,
	to distinguish them from three-way diffs.

	* diff3.c (using_to_diff3_block): Fold repeated code into loops.

	* diff3.c (make_3way_diff, process_diff): Have the *_end
	variable point to the next field to be changed, not to the last
	object allocated; this saves an if-then-else.

	* diff3.c (process_diff): Use D_NUMLINES instead of its definiens.

	* diff3.c: Make fns and vars static unless they must be external.

Wed Sep 30 09:21:59 1992  Paul Eggert  (eggert@twinsun.com)

	* ifdef.c (print_ifdef_lines): Add %L.  Optimize %leven if user
	specified it, as opposed to its being the default.

Tue Sep 29 19:01:28 1992  Paul Eggert  (eggert@twinsun.com)

	* diff.c (longopts, main): --{old,new,unchanged,changed}--group-format
	are new options, so that -D is no longer overloaded.  Set
	no_diff_means_no_output if --unchanged-{line,group}-format allows it.
	* diff.h (enum line_class): New type.
	(group_format, line_format): Use it to regularize option flags.
	All refs changed.

	* ifdef.c (format_ifdef, print_ifdef_lines): %n is no longer a format.

Mon Sep 28 04:51:42 1992  Paul Eggert  (eggert@twinsun.com)

	* diff.c (main, usage): Replace --line-prefix with the more general
	--{old,new,unchanged}-line-format options.

Sun Sep 27 05:38:13 1992  Paul Eggert  (eggert@twinsun.com)

	* diff.c (main): Add -E or --line-prefix option.  Add -D'=xxx'
	for common lines.  Change default -D< format from copy of -D>
	format to to -D<%<; similarly for default -D> format.
	* diff.h (common_format, line_prefix): New variables.
	* ifdef.c (format_ifdef): New function.
	(print_ifdef_script, print_ifdef_hunk, print_ifdef_lines):
	Use it for -D'=xxx', -E.

	* context.c (find_hunk): Glue together two non-ignorable changes that
	are exactly CONTEXT * 2 lines apart.  This shortens output, removes
	a behavioral discontinuity at CONTEXT = 0, and is more compatible
	with traditional diff.

	* io.c (find_identical_ends): Slurp stdin at most once.

	* util.c (print_line_line): line_flag is const char *.

Thu Sep 24 15:18:07 1992  Paul Eggert  (eggert@twinsun.com)

	* ifdef.c (print_ifdef_lines): New function, which fwrites a sequence
	of lines all at once for speed.

	(print_sdiff_script): Likewise.  Don't print 'q' at end,
	since that doesn't work with incomplete lines.
	* sdiff.c (interact): Don't assume diff output ends with 'q' line.
	* diff.h (ROBUST_OUTPUT_STYLE): OUTPUT_SDIFF is now robust.

	* sdiff.c (lf_copy, lf_snarf): Use memchr instead of index,

	* diff.h, util.c: Use it instead of MEMCHR_MISSING.

Sun Sep  6 07:25:49 1992  Paul Eggert (eggert@twinsun.com)

	* diff.h: (struct line_def): Replace this 3-word struct with char *.
	This uses less memory, particularly for large files with short lines.
	(struct file_data): New member linbuf_base counts number of lines
	in common prefix that are not recorded in linbuf;
	this uses less memory if files are identical or differ only at end.
	New member buffered_lines counts possibly differing lines.
	New member valid_lines counts valid data.
	New member alloc_lines - linbuf_base replaces old linbufsize.
	linbuf[0] now always points at first differing line.
	Remove unused members ltran, suffix_lines.
	Add const where appropriate.
	(Is_space): New macro, for consistent definition of `white space'.
	(excluded_filename, memchr, sip, slurp): New declarations.
	* ed.c (print_ed_hunk): Adjust to diff.h's struct changes.
	* context.c (pr_context_hunk): Likewise.
	* ifdef.c (print_ifdef_script): Likewise.
	* side.c (print_sdiff_script, print_half_line): Likewise.
	* util.c (analyze_hunk, line_cmp, print_1_line): Likewise.

	* analyze.c (shift_boundaries): Remove unneeded variable `end' and
	unnecessary comparisons of `preceding' and `other_preceding' against 0.
	(diff_2_files): When comparing files byte-by-byte for equality,
	don't slurp them all in at once; just compare them a buffer at a time.
	This can win big if they differ early on.
	Move some code to compare_files to enable this change.
	Use only one buffer for stdin with `diff - -'.
	(discard_confusing_lines, diff_2_files): Coalesce malloc/free calls.
	(build_script): Remove obsolete OUTPUT_RCS code.

	* diff.c (add_exclude, add_exclude_file, excluded_filename): New fns.
	(main): Use them for the new --exclude and --exclude-from options.
	(compare_files): Don't open a file unless it must be read.
	Treat `diff file file' and `diff file dir' similarly.
	Move some code here from diff_2_files to enable this.
	Simplify file vs dir warning.

	* dir.c (dir_sort): Support new --exclude* options.

	* io.c (struct equivclass): Put hash code and line length here instead
	of struct line_def, so that they can be shared.
	(find_and_hash_each_line): Compute equivalence class as we go,
	instead of doing it in a separate pass; this thrashes memory less.
	Make buckets realloc-able, since we can't preallocate them.
	Record one more line start than there are lines, so that we can compute
	any line's length by subtracting its start from the next line's,
	instead of storing the length explicitly.  This saves memory.
	Move prefix-handling code to find_identical_ends;
	this wins with large prefixes.
	Use Is_space, not is_space, for consistent treatment of white space.
	(prepare_text_end): New function.
	(find_identical_ends): Move slurping here, so it's only done when
	needed.  Work even if the buffers are the same (because of `diff - -').
	Compare prefixes a word at a time for speed.
	(find_equiv_class): Delete; now done by find_and_hash_each_line.
	(read_files): Don't slurp unless needed.
	find_equiv_class's work is now folded into find_and_hash_each_line.
	Don't copy stdin buffer if `diff - -'.
	Check for running out of primes.
	(sip, slurp): Split first part of `slurp' into another function `sip'.
	`sip' sets things up and perhaps reads the first ST_BLKSIZE buffer to
	see whether the file is binary; `slurp' now just finishes the job.
	This lets diff_2_files compare binary files lazily.
	Allocate a one-word sentinel to allow word-at-a-time prefix comparison.
	Count prefix lines only if needed, only count the first file's prefix.
	Don't bother to count suffix lines; it's never needed.
	Set up linbuf[0] to point at first differing line.
	(binary_file_p): Change test for binary files:
	if it has a null byte in its first buffer, it's binary.
	(primes): Add more primes.

	* util.c (line_cmp): Use bcmp for speed.
	Use Is_space, not is_space, for consistent treatment of white space.
	(translate_line_number): Internal line numbers now count from 0
	starting after the prefix.
	(memchr): New function (if memchr is missing).

	* Makefile.in: Document HAVE_ST_BLKSIZE.  Link with wildmat.o.
	* system.h (STAT_BLOCKSIZE): New macro based on HAVE_ST_BLKSIZE.
	* configure.in: Add AC_ST_BLKSIZE.
	* wildmat.c: New file.
