xref: /freebsd-10-stable/gnu/usr.bin/grep/ChangeLog

1999-11-18  Paul Eggert

	* m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a
	problem with the QNX 4.25 shell, which doesn't propagate exit
	status of failed commands inside shell assignments.

1999-11-13  Eli Zaretskii

	* doc/grep.texi: Minor markup and spelling corrections.  Use
	@noindent where appropriate.

	* PATCHES-{AM,AC}: rename to PATCHES.{AM,AC}

1999-11-12  Eli Zaretskii

	doc/grep.texi: Minor fixes and typos corrected.
	djgpp/README: Updated version.

1999-11-07  Paul Eggert

	* src/grep.c (usage): Fix misspelling.

1999-11-07  Paul Eggert

	Don't assume that the C library has re_set_syntax and friends.
	* src/Makefile.am (base_sources): Add regex.c, regex.h.
	(EXTRA_DIST): Remove regex.c, regex.h.

	* src/grep.c (prtext): Use out_quiet, not not_text, to decide
	whether to set pending to zero at the end.
	(not_text): Remove static variable, undoing latest change.
	(grep): Likewise.

	* doc/grep.texi: Tighten up the text, and fix some minor
	spelling and usage errors.  Use @enumerate rather than @table
	@samp, since it's better for Q&A format.  Add cross
	references.

1999-11-01 Alain Magloire

	* src/search.c: Use the more portable [[:alnum:]]
	to define a word instead of Ascii dependent [0-9A-Za-z]
	* src/grep.c: make not_text global to not display text when
	the context switches -A/-B/-C are use on binary files.
	* make grep-2.3g available for testing.
	* configure.in: drop support for --without-included-regex.
	This was generating bogus bug reports, since many GNU/Linux
	users have different version of glibc.  And glibc maintainers
	decided to drop k&r support. 
	
1999-11-01 Arnold D. Robbins

	* regex.c (init_syntax_once): move below definition of
	ISALNUM etc., then use ISALNUM to init the table, so that
	the word ops will work if i18n'ed.
	(SYNTAX): And subscript with 0xFF for Latin-1 characters.

1999-10-26  Alain Magloire

	* src/regex.c: Merge changes from GNU lib C.
	* Updated the *.po files

1999-10-26  Paul Eggert

	* src/grep.c (fillbuf): Don't report buffer size overflow if
	newalloc == save and maxalloc == save.  This can happen
	e.g. when reading a large page-aligned file that contains
	no newlines.

1999-10-21  Paul Eggert

	* src/grep.c (usage): Give example.  Clarify -F.
	Explain exit status more clearly.

1999-10-12  Paul Eggert

	* doc/grep.texi: Shorten the commentary about egrep and {.
	"BSD grep" -> "traditional grep".
	* doc/grep.1: Match recent changes to grep.texi.

1999-10-11  Paul Eggert

	* NEWS, doc/grep.1, doc/grep.texi: New option --mmap.
	* src/grep.c (mmap_option): New variable.
	(long_options, reset, usage): Add --mmap.
	Default is now read, not mmap.

	* doc/grep.1: Document -Z or --null.

1999-10-11  Paul Eggert

	* doc/grep.texi: Fix texinfo glitches.  POSIX -> POSIX.2 where
	appropriate.

1999-10-11  Paul Eggert

	* acconfig.h (ssize_t): New #undef.

	* configure.in (AC_CHECK_TYPE): Add ssize_t.

	* src/grep.c (PREFERRED_SAVE_FACTOR): New macro.
	(reset): If the buffer has already been allocated, set bufsalloc to
	be bufalloc / PREFERRED_SAVE_FACTOR.  This avoids problems when
	bufsalloc == bufalloc (possible after reading a large binary file).
	(reset): Use PREFERRED_SAVE_FACTOR instead of magic constant.
	Do not set bufbeg; nobody uses it.
	Always set buflim.
	Check for lseek error.
	Use SEEK_CUR, not a magic constant.
	(fillbuf): Return an error indication, not a count.
	All callers changed.
	Do not assume ssize_t fits in int.
	Use PREFERRED_SAVE_FACTOR instead of magic constant.
	Clean up mmap code.
	Do not attempt to mmap zero bytes.
	Check for lseek error.
	Use SEEK_SET, not a magic constant.
	Work correctly if read is interrupted.
	(grepfile): Work correctly if open or close is interrupted.

	* src/system.h (SEEK_SET, SEEK_CUR): New macros.

1999-10-02 Alain Magloire

	* src/regex.[ch]: upgrade from GNU lib C source tree.

	* make beta 2.3f available.

1999-10-02  Paul Eggert

	* NEWS: egrep is now equivalent to `grep -E'.
	The lower bound of an interval is not optional.
	You can specify a matcher multiple types without error.
	-u and -U are now allowed on non-DOS hosts, and have no effect.
	* doc/grep.texi: Likewise.
	* doc/grep.1: Likewise.
	Fix some troff bugs that prevented `groff' from rendering the page.

	* src/egrepmat.c, src/fgrepmat.c, src/grepmat.c (default_matcher):
	Remove.
	(matcher): Add.
	* src/grep.h (default_matcher): Remove.
	(matcher): Now exported from ?grepmat.c, not grep.c.

	* src/dfa.c (lex): If { would start an invalid interval specification,
        treat it as a normal character.
        Remove (broken) support for {,M} meaning {0,M}.
        Diagnose bogus intervals like {1,0}.
        (closure): maxrep is now -1 to indicate no limit, not zero;
        zero is a valid value for maxrep, meaning an upper bound of zero.

	* src/grep.c (short_options): New constant.
	(long_options, main): -u and -U are now supported on Unix,
	with no effect.
	(matcher): Removed; now defined by ?grepmat.c.
	(install_matcher): Renamed from setmatcher.
	(setmatcher): New function.
	(usage): Report new, more uniform option scheme.
	(main): Do not initialize matcher; ?grepmat.c now does this.
	Rely on setmatcher to catch matcher conflicts.
	Default matcher is "grep".

	* src/search.c (matchers):
	Remove "posix-egrep" matcher; no longer needed.
	(Ecompile): Likewise.
	The egrep matcher now has POSIX behavior.

	* tests/bre.tests: grep '\{' is no longer an error.
	Fix test for interval too large, and enable it.
	* tests/ere.tests: grep -E {1 is no longer an error
	Likewise for a{1, a{1a, a{1a}, a{1,x}.

1999-09-22  Paul Eggert

	* largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around GCC
	2.95.1 bug with HP-UX 10.20.

1999-09-12  Paul Eggert

	* src/grep.c (fillbuf): Fix typo: we sometimes reported
	arithmetic overflow even when there wasn't any.

1999-09-12  Paul Eggert

	* configure.in (AC_CHECK_FUNCS): Add memmove.

	* src/system.h (S_ISREG): New macro.
	(memmove): Define if ! defined HAVE_MEMMOVE && ! defined memmove,
	not if !defined STDC_HEADERS.  This is needed for SunOS 4.1.4,
	which defines STDC_HEADERS but lacks memmove.

	* src/grep.c (bufoffset): Needed even if !defined HAVE_MMAP.
	(reset): Always fstat the file, since we always need its size if it is
	regular.
	Similarly, get the buffer offset of every regular file.
	Set bufmapped to 0 if the file's initial offset is not a multiple
	of the page size.
	(fillbuf): Calculate an upper bound on how much memory we should
	allocate only for regular files, since we don't know the sizes of
	other files.
	Don't bother to check whether the file offset is a multiple of the page
	size, since we now do that just once in `reset'.
	When an mmapped area would fall past the end of the file, trim it to
	just before instead of giving up immediately and doing a `read';
	that avoids a worst-case behavior that could read half an mmapped file.
	Fix bug when computing offsets on hosts that don't have mmap.

1999-08-27  Paul Eggert

	* src/system.h (memmove): New macro.

	* src/grep.c (page_alloc): Reallocate the old buffer instead
	of having both old and new buffers active simultaneously.
	Remove valloc debugging variant, which no longer applies.

	(fillbuf): Rejigger the buffer allocation mechanism.  The old
	mechanism could allocate more than 10*N bytes for an N-byte
	file, which was excessive.  Check for arithmetic overflow a
	bit more carefully.

1999-08-25  Paul Eggert

	* src/grep.c (grepdir):
	Don't assume that st_ino and st_dev must be integers;
	POSIX.1 allows them to be floating-point (!).

	* src/vms_fab.h (arr_ptr): `:' -> `;' to fix typo.

1999-08-18  Alain Magloire

	* 2.3e snapshot.

1999-08-18  Alain Magloire

	* src/search.c: On a CRAY J90 system running UNICOS 8.0.
	Compilation of ./src/search.c failed because the declaration of
	the variable "regex":
	  static struct re_pattern_buffer regex;
	conflicted with a previous declaration search.c #includes "system.h",
	which #includes <stdlib.h>, which declares :
        extern char *regex __((char *_Re, char *_Subject, ...));
	The declaration in search.c is local to that one source file.
	I just changed its name to something less likely to conflict.
	(I called it "regexbuf", but you could pick any name you want.)
	Excerpt email from Dean Kopesky.

1999-08-16  Paul Eggert

	Upgrade large-file support to the version used in tar and
	textutils.

	* Makefile.am (ACLOCAL_AMFLAGS): Define to be empty.
	(M4DIR, ACINCLUDE_INPUTS): New macros.
	($(srcdir)/acinclude.m4): New rule.

	* configure.in (AC_CANONICAL_HOST, AM_C_PROTOTYPES): Add.
	(AC_SYS_LARGEFILE): Renamed from AC_LFS, for compatibility
	with what should appear in the next autoconf release.

	* m4/largefile.m4: Renamed from m4/lfs.m4.

	* src/ansi2knr.1, src/ansi2knr.c, config.guess, config.sub:
	New files.  config.guess and config.sub ar needed by the new
	AC_SYS_LARGEFILE.  ansi2knr is needed by AM_C_PROTOTYPES,
	which in turn is needed by the new AC_SYS_LARGEFILE.

1999-08-16  Alain Magloire

	* 2.3d snapshot on ftp server.

1999-07-26  Paul Eggert

Several GNU tools have options to process arbitrary file names, even
file names that contain newline characters.  These include `find
-print0', `perl -0', `sort -z', and `xargs -0'.  It'd be handy if GNU
grep also processed such file names.  Here's a proposed patch to do
this, relative to grep 2.3c.  This patch introduces two options, one
for the data, and one for the file names.  (Sometimes one wants
null-terminated file names in the output, and sometimes one wants to
process lists of null-terminated strings, and these are orthogonal
axes.)

        * NEWS, doc/grep.texi: New -z or --null-data and -Z or --null options.
        * src/grep.c (long_options, usage, main): Likewise.

        * src/dfa.h (dfasyntax): New eol parameter.
        * src/dfa.c (eolbyte): New var.
        (dfasyntax): Set it from new parameter.
        (lex, dfastat, build_state, dfaexec): Use it instead of '\n'.

        * src/grep.h (eolbyte): New decl.
        * src/grep.c (eolbyte): New var.
        (nlscan, prpending, prtext, grepbuf, grep): Use it instead of '\n'.
        (filename_mask): New var.
        (prline, grepfile): Output NUL separator if filename_mask is zero.
        (grep): Look for '\200' as the hallmark of a binary file, not '\0',
        if -z or --null-data is specified, since it implies that '\0' is
        expected as text.

        * src/search.c (Gcompile, Ecompile): Pass eolbyte to dfasyntax.
        (EGexecute, Fexecute): Use eolbyte instead of '\n'.

1999-06-15 Alain Magloire

	* src/grep.c, doc/grep{1,texi} : 
	--revert-match should be --invert-match.
	Correction proposed by Karl Berry.

1999-06-12 Alain Magloire

	* doc/grep.{1,texi}: add description for --with-filename.
	Noted missing by UEBAYASHI Masao.

1999-03-17 Paul Eggert

	* NEWS: Add GREP_OPTIONS.

	* doc/grep.texi: Document GREP_OPTIONS, and the other
	environment variables.  Fix doc for [:blank:], [:cntrl:], [:punct:].

	* src/grep.c (prepend_args, prepend_default_options): New functions.
	(main): Use them to implement GREP_OPTIONS.
	* src/system.h (getenv): New decl.

1999-03-16 Volker Borchert

	* configure.in: Use case case ... esac for  checking Visual C++.
	When ${CC} contains options it was not recognize.

1999-03-07 Paul Eggert

	* src/grep.c (usage): Don't report -E, -F, and -G unless we're grep.
	(main): Don't match options -E, -F, and -G unless we're grep.
	Remove after-the-fact check for options -E, -F, and -G, since
	they're no longer needed.

1999-03-05  Eli Zaretskii

	* src/grep.c (main): Print the name of the default matcher instead
	of just "grep".                                                        

1999-02-06 Alain Magloire

	* tests/*.awk : Linux users are seeing "Broken Pipe" on make check.
	The problem is that grep does not drain its stdin, thus the previous
	process in the pipeline receives a SIGPIPE.  Other shells are silent
	about this.  There is actually no failure, since the broken pipe is
	expected.  You can work around it by changing the pipeline, so that
	the input is drained, like this:
	status=`echo 'check' | { ${GREP} -E -e pattern >/dev/null 2>&1;
	echo $?; cat >/dev/null; }`; if test $status -ne $errnu then ... fi
	Excerpt email from Andreas Schwab.                              

1999-02-23 Alain Magloire

	* src/grep.c : Restrict the use of -E, -F, -G
	to only grep driver, Posix behaviour. {f,e}grep
	the matcher is already set. This change may brake
	scripts, warn in NEWS.

	* doc/grep.{1,texi} : -C takes arguments, upgrade manual.

	* beta 2.3a

1999-02-23 Alain Magloire

	* configure.in : Change the configure VC test from
	'test x$ac_cv_prog_CC = xcl;' to 'test x"$ac_cv_prog_CC" = xcl;'
	Email from Joshua R. Poulson.

1999-02-23 Paul Eggert

	Fix porting bug reported by Amakawa Shuhei for SunOS 4.1.4-JL.
	The btowc.c shipped with grep 2.3 is incorrect for Solaris
	2.5.1 and earlier, as it assumes UTF8, which these OSes do not
	support.  Solaris 7 supports btowc, so there's no need to ship
	a substitute for it.  The only questionable case is Solaris
	2.6, which lacks btowc but does support UTF8.  However, 2.6
	supports UTF8 but only as a demonstration (for an English
	locale!); Japanese Solaris 2.6 users typically use EUC, or
	sometimes shift-JIS, but they cannot use UTF8 since Japanese
	UTF8 is not supported.  Hence there's no point to having grep
	substitute a btowc that uses UTF8, as it is either redundant,
	or it will almost invariably have incorrect behavior.

	* configure.in (AC_CHECK_HEADERS): Don't set USE_WCHAR.
	(AC_CHECK_FUNCS): Add btowc, wctype.
	(AC_REPLACE_FUNCS): Don't replace btowc; our replacement is
	invariably doing the wrong thing anyway, at least on SunOS/Solaris.
	Don't bother to check for wctype in -lw, as we don't support
	wide characters on Solaris 2.5.1 or earlier anyway.

	* bootstrap/Makefile.try (OBJS): Remove btowc.$(OBJEXT).

	* src/btowc.c: Removed; no longer needed.

1999-02-19  Paul Eggert

	* NEWS: Fix typo when talking about the old behavior of
	silently skipping directories; it was grep 2.1, not grep 2.2.

1999-02-15 Alain Magloire

	* bootstrap/Makefile.try : add DJGPP DEFS.
	Done by Elie Zaretsckii.

1999-02-14 Alain Magloire

	* m4/gettext.m4 : Guard [] with changequote.
	From Elie Zaretskii.

	* djgpp/config.bat : Makefile.in.in --> Makefile.in-in
	From Elie Zaretskii.

	* src/dosbuf: k&r function parameter.

	* release of 2.3.

1999-02-10 Alain Magloire

	* bootstrap/{Makefile{try,am},REAMDE} : skeleton
	provided for system lacking the tools to autoconfigure.

	* src/{e,f,}grepmat.c: added guard [HAVE_CONFIG_H]

1999-02-10 Alain Magloire

	* PATCHES-AC, PATCHES-AM: updated.

	* m4/regex.m4 : updated.

1999-02-05 Eli Zaretskii

	* m4/gettext.m4 : Support DOS-style D:/foo/bar absolute file
	names.

	* aclocal.m4 (DJGPP) : Use $DJ_GPP instead, since changing the
	latter prevents GCC from finding headers and libraries.

	* djgpp/config.bat: Make building from another directory work

	* djgpp/config.sed: Remove redundant command wich edited path
	separator: now done by configure.

	* src/grep.c [O_BINARY]: Add prototype for undossify_input.

	* doc/grep.texi (Introduction): Typo fixed.

1999-02-03 Alain Magloire

	* grep-2.2f beta release.

1999-02-02 Alain Magloire

	* m4/{djgpp,envsep,glibc,regex,dosfile,isc-posix}.m4 :
	New files to aid configuration and unload configure.in.
	* m4/Makefile.am : updated.
	* src/btowc.c : protect for wchar.h

1999-01-28 Alain Magloire

	* intl/Makefile.in: Replace .o with .${ac_objext} where necessary.
	Work around a limitation of Visual C++ on Cygwin32.
	* acconfig.h configure.in: Define `alloca' as `_alloca' when CC=cl.
	This little hack was suggested by Ian Roxborough <irox@cygnus.com>.
	Patch forwarded by Ben Elliston.

1999-01-28 Alain Magloire

	* PATCHES-AM: New file. A small patch for automake-1.4, use $(sep)
	as the path separator base on @SEP@.
	* PATCHES-AC configure.in : updated for autoconf-13.
 
1999-01-27 Volker Borchert

	* grep.c: fgrep -NUM not working correctly.
	add the argument number to digit_args_val.

1999-01-22 Paul Eggert

	Prevent grep -r from recursing infinitely through directory loops via
	symbolic links.

	* grep.c (struct stats): New type.
	(stats_base): New var.
	(bufstat): Remove; subsumed by stats->stat.
	(reset, fillbuf, grep, grepdir, grepfile): Pass struct stats * arg,
	for directory loop checking; use this instead of the bufstat global.
	All callers changed.
	(grepfile): Stat the file before invoking grepdir.
	(grepdir): Assume that the argument has already been statted.
	No longer a need for a directory size argument, since it
	can be gotten from the struct stats * argument.
	Check for directory loops.
	Create linked list of directories currently being visited,
	to detect loops.

1998-12-29 Kaveh R. Ghazi

	intl/localealias.c: When building grep-2.2e using cc on Irix4,
	I needed the following patch to intl/localealias.c.
	(Its the same patch used by fileutils-4.0.) The patch resolves
	conflicts between char* and unsigned char* in the i18n code.

1998-12-10 Alain Magloire

	* src/grep.c : Typo in contex -->context
	Noted by  Vladimir Michl.

1998-12-01  Alain Magloire

	* doc/Makefile.am djgpp/Makefile.am m4/Makefile.am vms/Makefile.am:
	New files.

	* m4/progtest.m4: proctect '[]' from m4.
	Noted by Eli Z.

	* PATCHES-AC: New file, add the patch for autoconf in the dist.

	* acconfig.h: (HAVE_DOS_FILENAME)

	* TODO: updated.

	* src/search.c: remove obsolete 'gegrep,ggrep,gnugrep'
	matchers. grep no longer depend on argv[0].

	* grep-2.2e beta to test DJGPP port.

1998-11-28  Paul Eggert

	Various portability enhancements:
	- Don't assume that O_BINARY implies DOS.  Use separate
	macros D_OK (for DOS-like directory access) and
	HAVE_DOS_FILE_NAMES (for DOS-like file names).
	- Don't assume that off_t fits into long; it doesn't on Solaris 2.6.
	- Have is_EISDIR set errno properly on hosts with screwed-up EISDIR.
	- Treat ':' specially in DOS file names only if it's the end of a
	drive specifier.
	- Protect against errno < 0.

	* src/grep.c (is_EISDIR): Move defn to system.h.
	(print_offset_sep): New function.
	(fillbuf): Remove redundant test of O_BINARY.
	(totalcc, totalnl): Now of type off_t.
	(prline): Use print_offset_sep to print file offsets.
	(grepfile): Don't set e to EISDIR; that's is_EISDIR's responsibility
	on machines that don't work properly with EISDIR.
	(grepdir): Don't assume ':' means slash on all DOS filenames;
	it means it only in the file prefix.

	* src/system.h (strerror): Check for negative error numbers.
	(is_EISDIR): Depend on D_OK, not O_BINARY.
	(SET_BINARY): Depend on HAVE_SETMODE, not __DJGPP__.
	(IS_SLASH, FILESYSTEM_PREFIX_LEN): Depend on HAVE_DOS_FILE_NAMES,
	not O_BINARY.
	(CHAR_BIT): New macro.

	* src/dosbuf.c (struct dos_map):
	pos and add members are now of type off_t.
	(dos_stripped_crs): Now of type off_t.
	(dossified_pos): Now accepts arg and returns value of type off_t.

	* configure.in (AC_CHECK_FUNCS): Add setmode.
	(HAVE_DOS_FILENAMES): New macro

1998-11-27  Eli Zaretskii

	* djgpp/config.sed: New file, a Sed script to edit configure
	script before running it on DOS/Windows.
	* djgpp/config.bat: Updated to handle po2tbl.sed.in and
	po/Makefile.in.in on DOS filesystems, and to run config.sed.

1998-11-24  Jim Meyering

	* src/grep.c : Typo s/infalid/invalid/
	Also noted by Stanislav Brabec.

1998-11-24  Eli Zaretskii

	* doc/grep.texi: I found and corrected several typos.
	I believe the GNU standards require the section that describes the
	options to the programs to be called ``Invoking'' or ``Invoking
	<program-name>''.  This is so users and programs can easily find
	that node in any Info file.  So I changed the name of the
	`Options' chapter to `Invoking', and corrected the
	cross-references accordingly.
	I added some markup to things like file names and options.
	I added some additional index entries where that seemed useful.
	I also corrected some index entries, such as "@cindex [:alnum:]",
	which used a colon in them (the colons confuse Info readers).

1998-11-24  Alain Magloire

	* grep/doc/grep.texi : -h is not use for help.
	Nit spotted by Jim Meyering.

1998-11-23  Alain Magloire

	* doc: New directory, grep.1, {e,f}grep.man move here
	* doc/grep.texi: New info manual
	* doc/version.texi: New
	* doc/Makefile.am: New
	* tests/{ere,bre}.*: New files. The spencer2 test is split
	in two ere/bre.
	* config.hin: New, config.h.in rename to config.hin for OS
	with limited file system aka DOS.

	* grep-2.2d release for beta.

1998-11-18  Alain Magloire

	* src/regex.[ch] : Updated from GLibc, previous patches were
	integrate by Ulrich Drepper and some added ones.

1998-11-16  Paul Eggert

	* grep.h (__attribute__): New macro, if not GCC.
	(fatal): Add __attribute__((noreturn)).
	* grep.c (usage): Add __attribute__((noreturn)).

1998-11-16  Paul Eggert

	the console device.
	(is_EISDIR): Don't define if already defined.  Accept a second
	argument, the file name; all callers changed.

	Nit from Paul Eggert.

1998-11-06 Alain Magloire

1998-04-16 Alain Magloire

	* tests/{status,empty}.sh: wrong return status.

	* src/grep.c: Remove the REGEX part in usage (), it was
	consider overkill by most.

1998-04-14  Eli Zaretskii

	* djgpp/config.bat: Support file names with multiple dots on all
	platforms.

	* djgpp/README: Add instructions about file names illegal on
	MS-DOS.

1998-04-13 Alain Magloire

	* src/dfa.c: by "popular" demand reverse
	back to '_' not word-constituent.

	* grep-2.1.1c available for testing.

1998-04-13  Karl Heuer

	* src/grep.c: (a) The directory check is done too early:
	logically, if the argument is "-", then it refers to standard
	input, regardless of whether there's something in the file
	system answering to "-".
	(b) The sh command "grep -l root /etc/passwd /etc/group 0<&-"
	prints "(standard input)" instead of "/etc/passwd", because it
	mistakenly believes that a named file will never be opened on fd
	0.  The string "(standard input)" should be based on the file
	having been originally specified as "-", rather than making
	assumptions about the fd.
	(c) the code that calls close(fd) is being done outside of the
	test for a bad fd.  Thus, if the open failed, this code will
	attempt to close(-1).  It should be done inside the "fd != -1"
	branch.
	This patch addresses all three of these problems.

1998-04-13 Alain Magloire

	* configure.in: remove the deprecated AC_ISC_POSIX macro.
	Spotted by Karl Heuer.

	buffer.  Spotted by Paul Eggert.

1998-03-27  Alain Magloire

	* grep-2.1.1b.tar.gz available.

	* src/regex.c: CLASS_CHAR_MAX set to 256 instead of 6
	when WCTYPE and WCHAR are not defined. When class names
	where bigger then 6, it will not detect an error.
	example '[[:alphabet:]]'.

	* Updated the copyright of the files with emacs.
	With emacs Jim :).

1998-03-26 Jim Meyering

	* src/dfa.c (IS_WORD_CONSTITUENT): Define.

1998-03-25  Alain Magloire

	* tests/warning.sh: typos and replace the echos with
	a simple cat.
	Noted By Jim Meyering.

	* src/regex.c: #undef ISASCII and ISPRINT before defining
	them(On Solaris it was define).
	Pattern 'a[[:]:]]b' is an invalid char class and the error
	from regex was 1(REG_NOMATCH) instead of 2 (REG_ECTYPE).
	Fix with help from Ulrich Drepper.

	* src/grep.c (usage): Ulrich wrote: "A single printf should
	not have more than 900 bytes. For translation reasons the
	text shouldn't be split in too many pieces since this is
	tiresome and also does not help to generate a consistent picture."
	Noted by Ulrich Drepper.
	* src/grep.c (usage): Dig out and old patch from
	Franc,ois to explain the regex in usage().
	Ideas from Franc,ois Pinard.

1998-03-23 Alain Magloire

	* testing: grep-2.1.1a for testing.

	* configure.in: Solaris needs '-lw' if we use wchar/wctype
	functions.
	* src/btowc.c: New file from GNU libc. Solaris 2.5 don't
	have it define.
	* configure.in : check for btowc ().

	* regex.c: Include <wchar.h> before <wctype.h>, to work around
	a Solaris 2.5 bug.
	Patch provided by Paul Eggert.

	variables.
	Done by Paul Eggert.

	* src/grep.c (usage): change prep.ai.mit.edu for gnu.org.

1998-03-18 Alain Magloire

	* src/grep.c (usage): Formating the --help message a bit off.
	Noted by William Bader.

	* src/grep.c (main): When checking conflicting matcher for option -E the
	matcher was to "egrep" instead of "posix-egrep".
	Reported by kwzh@gnu.org.

	* src/grep.c: Typos and rewording the --help message.
	Reported by Karl Heuer.

	* src/grep.1: The man page wording :
	  A regular expression matching a single character may be
	  followed by one of several repetition operators:
	is unclear since 'x(yz)*z' is a valid regex.
	Remove the "matching a single character".
	Suggested by Harald Hanche-Olsen.

	* src/grep.c (main): `-f /dev/null' now specifies no patterns
	and therfore matches nothing.
	Reported by Jorge Stolfi.
	Patched by Paul Eggert.

1998-03-10 Alain Magloire

	* Ice storm 98(el nino). Lost grep repository disk,
	and my $HOME directory, etc ..

	and start from grep-2.1.
	sigh ....

1997-11-01 Alain Magloire

	* src/grep.c: For the long options, the problems are:
	--file appears in the option table as 'no_argument'
	instead of 'required_argument'.
	--files-with-matches is missing from the option table.
	The help lists '--fixed-strings' as the long option for -F,
	the table has '--fixed-regexp'.
	--regexp appears in the option table as 'no_argument'
	instead of 'required_argument'.
	--with-filename is missing from the option table.
	Reported by Grant McDorman and Krishna Sethuraman.

1997-10-19 Alain Magloire

	* src/grep.c: the option "with-filename was not in the arg table.
	Corrected by Jim Hand.

	* GNU gettext library from gettext-0.10.32.

	* src/grep.c: reverse back to greping directories,
	One could skip the error message by defining
	SKIP_DIR_ERROR. There is no clear way of doing
	things, I hope to setle this on the next majore release
	Thanks Paul Eggert, Eli Zaretskii and gnits for the
	exchange.

	* tests/status.sh: add this check to make sure
	That the return status code is ok.

1997-10-10 Andreas Schwab

	[O_BINARY]: Pass additional DOS-specific options to getopt_long
	and handle them.  Call stat before attempting to open the file, in

	directories).  Switch the input descriptor to binary mode, unless
	it is a terminal device.

	* system.h [O_BINARY]: Define macros to switch a handle to binary
	mode, so binary files could be grep'ed on MS-DOS and MS-Windows.
	[HAVE_SETLOCALE]: Test for HAVE_SETLOCALE instead of
	HAVE_LC_MESSAGES, to prevent compilation error in grep.c on
	systems which don't define HAVE_LC_MESSAGES, but have setlocale.

	* dosbuf.c: New file, functions specific for MS-DOS/MS-Windows.
	(guess_type, undossify_input, dossified_pos): New functions.

	* djgpp/config.h, djgpp/config.bat, djgpp/main.mak, djgpp/src.mak,

	From Kaveh R. Ghazi <ghazi@caip.rutgers.edu>.
	From Ulrich Drepper <drepper@cygnus.com>.

	* Many files: use PARAMS instead of __STDC__ for prototypes.
	From Jim Meyering <meyering@eng.ascend.com>.
	Patch provided by Kaveh R. Ghazi <ghazi@caip.rutgers.edu>.

	* dfa.[ch]: uses the one in gawk-3.0.3 with the patch from

	* grep.1: a note to say -l, -L, -q stop on first match.
	Noted by Andrew Beattie <gaffer@tug.com>.

	* grep.c: refuse to scan if the file is a directory.
	This was causing problems on SUNs. If the directory contains
	a file that could match the pattern, garbage was display.

	regex package. Change the way the tests were done to be more
	conformant to automake.

	From Jim Meyering <meyering@eng.ascend.com>.

	* grep.c:usage() more consistency in the --help.

	* egrep, fgrep were links This is in violation of GNU standards:
	"Please don't make the behavior of a utility depend on the name used
	to invoke it.  It is useful sometimes to make a link to a utility with
	a different name, and that should not change what it does."
	For now egrep and fgrep will be copies of grep. A better scheme
	should be found later.
	After discussion with Tom Tromey <tromey@cygnus.com>.

	* fgrep.man and egrep.man included: They are stubs that call grep.1.
	* Makefile.am: modified to install {f,e,}grep[,.1].

	setbit, clrbit to avoid conflict with HP-UX sys/param.h macros.

	* memchr.c: New file, from GNU libc.
	* grep.c (memchr): Remove definition.
	* configure.in: Use AC_REPLACE_FUNCS for memchr.

	* configure.in: Remove unused checks for memalign and unsigned char.
	* grep.c: HAVE_WORKING_MMAP -> HAVE_MMAP.

	* system.h: New file.
	* dfa.c, kwset.c, grep.c, search.c: Use it instead of duplicating
	portability boilerplate.

	* grep.c: Include sys/types.h once, instead of three times
	conditionally.
	* dfa.c, kwset.c, search.c: Include sys/types.h unconditionally,
	to always try to get size_t (needed on some old SysV's).

	* dfa.c: Define strchr in terms of index, not the other way around.
	* search.c: Use memcpy instead of bcopy.
