2001-07-29  Alain Magloire

	David Clissold, wrote:
	a small bug in the GNU grep 2.4.2, which may have gone unnoticed
	because it only causes a failure if building on a system with large
	files enabled (e.g. an "off_t" is a "long long" rather than a "long").
	savedir() takes on off_t argument, but in grepdir() the parameter
	is cast to an (unsigned).  Well, if an off_t is larger than an int,
	the value gets truncated.  This would not normally have an effect on a
	little-endian platform (unless the file is >2GB), but on a big-endian
	system it will always fail.  The external effect is that
	"grep -r foo dir_name" fails with ENOMEM (from malloc() within
	savedir()).

	* grep/src/grep.c (grepdir): Remove the (unsigned) cast when calling
	savedir().
	Patch from David Clissold.

2001-07-29  Alain Magloire

	* grep/doc/grep.texi: In Bugs report use {n,m} for consistency.
	* grep/doc/grep.1: Likewised.
	Noted by Steven Lucy.

	* lib/posix/regex.h: Likewise.

2001-02-17  Paul Eggert

	Stop trying to support hosts that have nonstandard declarations for
	mbrtowc and/or mbstate_t.  It's not worth the portability hassle.

	* lib/quotearg.c (mbrtowc, mbsinit): Remove workaround macros
	for hosts that have mbrtowc but not mbstate_t, as we now
	insist on proper declarations for both before using mbrtowc.

2001-03-18  Alain Magloire

	* configure.in: Call AC_MBSTATE_T.
	* Makefile.am: Add mbstate_t.m4

	bug: buffer was doubling in size in many cases where it didn't
	have to.

2001-03-17  Paul Eggert

	* src/grep.c (fillbuf): Avoid unnecessary division by 2.
	Don't check xrealloc return value; it's guaranteed to be nonzero.
	(fillbuf, grepdir): Use xalloc_die rather than error; it's shorter.

2001-03-17  Alain Magloire

	* src/grep.c (context_length_arg): error () passing wrong format.
	Spotted by Jim Meyering.

2001-03-07  Alain Magloire

	* README-alpha: Removed reference to GNU tar, add the location
	of the CVSROOT.

2001-03-06  Alain Magloire

	Only the Regex patterns should be split in an array, patterns[].
	The dfa and KWset compiled patterns should remain global and the
	patterns compiled all at once.

	* src/search.c: include "error.h" and "xalloc.h" to get prototyping
	of x*alloc() and error().
	(kwsinit): Reverse to previous behaviour and takes no argument.
	(kwsmusts): Likewised.
	(Gcompile): For the regex pattern, split them and each pattern
	is put in different compiled structure patterns[]. The patterns
	are given to dfacomp() and kwsmusts() as is.
	(Ecompile): Likewised.
	(Fcompile): Reverse to the old behaviour of compiling the enire
	patterns in one shot.
	(EGexecute): If falling to GNU regex for the matching, loop in the
	array of compile patterns[] to find a match.
	(error): Many error () were call with arguments in the wrong order.
	* tests/file.sh: Simple test to check for pattern in files.

	Reaction to bug report fired by Greg Louis <[e-mail]>
