Raw Blame History

2000-01-28 Alain Magloire
* src/grep.c (usage): The example "%s -i 'hello.*world' could
lead to confusion when progname is 'fgrep.
Noted by Akim Demaille.
* configure.in: Reenable, jm_INCLUDE_REGEX() since we now
track GNU lib C.
* src/Makefile.am: EXTRA_DIST new macros with regex.c regex.h.
Requested By Ulrich Drepper.
2000-01-25 Paul Eggert
* src/grep.c (grep): If the final byte of an input file is not
a newline, grep now silently supplies one.
* doc/grep.texi, NEWS: Likewise.
2000-01-25 Paul Eggert
* NEWS, doc/grep.1, doc/grep.texi: Add -I option.
* src/grep.c (short_options, usage, main): Likewise.
* doc/grep.texi: Fix some incorrect references to ASCII.
2000-01-25 Paul Eggert
* doc/grep.1: Simplify synopsis; sort options; mention
environment variables; clean up some minor gaffes.
2000-01-25 Paul Eggert
* doc/grep.texi:
Fix some errors in description of [:print:] and the like.
2000-01-23 Paul Eggert
* src/dfa.c (FETCH, lex): Put brackets around if-body to avoid
GCC warning about ambiguous if-then-else.
2000-01-23 Paul Eggert
* src/regex.c (GET_UNSIGNED_NUMBER): Allow only ASCII digits.
* src/dfa.c (ISASCIIDIGIT): New macro.
(lex): Use it instead of ISDIGIT.
2000-01-23 Paul Eggert
The bug is that regular expression ranges like [a-z] compare raw
byte codes to the range boundaries, whereas POSIX says that they
should use the current collating sequence instead. For example,
in Solaris 7 with LC_ALL=en_US, the command
echo x | grep '[ -~]'
outputs 'x', but it shouldn't output anything since ' ' and '~'
sort before all letters in that locale.
* src/regex.c (compile_range): When matching a character
range, use the current collating sequence, as POSIX requires.
* src/dfa.c (lex): Likewise.
2000-01-20 Alain Magloire
* tests/Makefile.am (dist-hook): Added new rule to make sure
that the shell scripts have the right permissions.
* src/posix/Makefile.am (EXTRA_DIST): added regex.h in the
distribution.
* THANKS: updated.
2000-01-18 Alain Magloire
* Rectification the initial patch to add --binary-file option
was done by Ruslan Ermilov.
2000-01-17 Paul Eggert
Sync with sources of fileutils 4.0n, tar 1.13.17, glibc 2.1.3a1.
Convert to ANSI C prototypes (using ansi2knr for backwards
compatibility), as this makes it easier to sync.
* configure.in (AC_OBJEXT): Spell in a funny way, to work around
a bug in automake 1.4 with ansi2knr.
(LIBOBJS): Add assignment so that .o files in LIBOBJS are also built
via the ANSI2KNR-filtering rules.
(AC_OUTPUT): Add src/posix/Makefile.
* src/Makefile.am (AUTOMAKE_OPTIONS): Add ansi2knr.
(SUBDIRS): New macro.
* src/ansi2knr.1, src/ansi2knr.c, src/posix/Makefile.am: New files.
* src/dfa.c, src/dosbuf.c, src/grep.c, src/kwset.c, src/search.c,
src/vms_fab.c:
Use prototypes for function definitions.
* src/grep.c (main): Use int counter for default context,
fixing an ANSI portability bug uncovered by the above changes.
* config.guess, config.sub, install-sh, missing, src/alloca.c,
src/getpagesize.h, src/memchr.c, src/savedir.c, src/savedir.h,
src/stpcpy.c:
Upgrade to latest version from fileutils 4.0n.
* src/getopt.c, src/getopt.h, src/getopt1.c: Upgrade to latest
version from tar 1.13.17.
* src/obstack.c, src/obstack.h, src/regex.c, src/regex.h:
Upgrade to glibc 2.1.3 alpha 1, with K&R C portability fix.
* src/posix/regex.h: New file, from glibc 2.1.3 alpha 1.
2000-01-04 Paul Eggert
Inititial patch from David O'Brien.
Add --binary-files option.
* NEWS, doc/grep.1, doc/grep.texi: Document it.
* src/grep.c (BINARY_FILES_OPTION): New constant.
(long_options, grep, usage, main): New --binary-files option.
(binary_files): New var.
* src/system.h (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM, CHAR_MAX):
New macros.
(INT_MAX, UCHAR_MAX): Define in terms of TYPE_MAXIMUM.
2000-01-04 Paul Eggert
* savedir.c (savedir): Don't store past the end of an array if
name_size is zero and the directory is empty.
Reported by Dima Barsky <dima@pwd.hp.com>.
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.

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

* 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).

-C/-NUM, regardless of order.
(long_options): Let -C/--context take an optional argument.
1998-11-03 Alain Magloire
* src/dfa.c: HP-UX define clrbit/setbit as macros in <sys/param.h>

(main): If open fails because the file is a directory, and if we're
skipping directories, don't report an error.
Remove special case for DOS and Windows.
* src/dosbuf.c (guess_type): Use the same method for guessing whether a
file is binary as grep.c's grep does.
There's no longer any need to declare `bp' to be unsigned.
1998-04-26 Alain Magloire
* grep-2.2 release.

Noted and patched by Joel N. Weber II.
1998-04-17 Kaveh R. Ghazi
* src/dfa.h: Don't define `const', trust autoconf to handle it.
1998-04-16 Alain Magloire
* tests/{status,empty}.sh: wrong return status.
* src/grep.c: Remove the REGEX part in usage (), it was

* 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.

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.
* tests/status.sh: new file to check return status code.
* tests/empty.sh: new file to check for empty pattern.

unless the user specified one of the CPPFLAGS, LDFLAGS, or LIBS
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,

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

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.

characters at end of line.
(prline) [O_BINARY]: Report correct byte offsets, even though CR
characters were stripped when reading the file.
(usage) [O_BINARY]: Add DOS-specific options.

[O_BINARY]: Pass additional DOS-specific options to getopt_long
and handle them. Call stat before attempting to open the file, in
case it is a directory (DOS will fail the open call for
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.

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.
