2
3 * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a
4 problem with the QNX 4.25 shell, which doesn't propagate exit
5 status of failed commands inside shell assignments.
6
71999-11-13 Eli Zaretskii
8
9 * doc/grep.texi: Minor markup and spelling corrections. Use
10 @noindent where appropriate.
11
12 * PATCHES-{AM,AC}: rename to PATCHES.{AM,AC}
13
141999-11-12 Eli Zaretskii
15
16 doc/grep.texi: Minor fixes and typos corrected.
17 djgpp/README: Updated version.
18
191999-11-07 Paul Eggert
20
21 * src/grep.c (usage): Fix misspelling.
22
231999-11-07 Paul Eggert
24
25 Don't assume that the C library has re_set_syntax and friends.
26 * src/Makefile.am (base_sources): Add regex.c, regex.h.
27 (EXTRA_DIST): Remove regex.c, regex.h.
28
29 * src/grep.c (prtext): Use out_quiet, not not_text, to decide
30 whether to set pending to zero at the end.
31 (not_text): Remove static variable, undoing latest change.
32 (grep): Likewise.
33
34 * doc/grep.texi: Tighten up the text, and fix some minor
35 spelling and usage errors. Use @enumerate rather than @table
36 @samp, since it's better for Q&A format. Add cross
37 references.
38
391999-11-01 Alain Magloire
40
41 * src/search.c: Use the more portable [[:alnum:]]
42 to define a word instead of Ascii dependent [0-9A-Za-z]
43 * src/grep.c: make not_text global to not display text when
44 the context switches -A/-B/-C are use on binary files.
45 * make grep-2.3g available for testing.
46 * configure.in: drop support for --without-included-regex.
47 This was generating bogus bug reports, since many GNU/Linux
48 users have different version of glibc. And glibc maintainers
49 decided to drop k&r support.
50
511999-11-01 Arnold D. Robbins
52
53 * regex.c (init_syntax_once): move below definition of
54 ISALNUM etc., then use ISALNUM to init the table, so that
55 the word ops will work if i18n'ed.
56 (SYNTAX): And subscript with 0xFF for Latin-1 characters.
57
581999-10-26 Alain Magloire
59
60 * src/regex.c: Merge changes from GNU lib C.
61 * Updated the *.po files
62
631999-10-26 Paul Eggert
64
65 * src/grep.c (fillbuf): Don't report buffer size overflow if
66 newalloc == save and maxalloc == save. This can happen
67 e.g. when reading a large page-aligned file that contains
68 no newlines.
69
701999-10-21 Paul Eggert
71
72 * src/grep.c (usage): Give example. Clarify -F.
73 Explain exit status more clearly.
74
751999-10-12 Paul Eggert
76
77 * doc/grep.texi: Shorten the commentary about egrep and {.
78 "BSD grep" -> "traditional grep".
79 * doc/grep.1: Match recent changes to grep.texi.
80
811999-10-11 Paul Eggert
82
83 * NEWS, doc/grep.1, doc/grep.texi: New option --mmap.
84 * src/grep.c (mmap_option): New variable.
85 (long_options, reset, usage): Add --mmap.
86 Default is now read, not mmap.
87
88 * doc/grep.1: Document -Z or --null.
89
901999-10-11 Paul Eggert
91
92 * doc/grep.texi: Fix texinfo glitches. POSIX -> POSIX.2 where
93 appropriate.
94
951999-10-11 Paul Eggert
96
97 * acconfig.h (ssize_t): New #undef.
98
99 * configure.in (AC_CHECK_TYPE): Add ssize_t.
100
101 * src/grep.c (PREFERRED_SAVE_FACTOR): New macro.
102 (reset): If the buffer has already been allocated, set bufsalloc to
103 be bufalloc / PREFERRED_SAVE_FACTOR. This avoids problems when
104 bufsalloc == bufalloc (possible after reading a large binary file).
105 (reset): Use PREFERRED_SAVE_FACTOR instead of magic constant.
106 Do not set bufbeg; nobody uses it.
107 Always set buflim.
108 Check for lseek error.
109 Use SEEK_CUR, not a magic constant.
110 (fillbuf): Return an error indication, not a count.
111 All callers changed.
112 Do not assume ssize_t fits in int.
113 Use PREFERRED_SAVE_FACTOR instead of magic constant.
114 Clean up mmap code.
115 Do not attempt to mmap zero bytes.
116 Check for lseek error.
117 Use SEEK_SET, not a magic constant.
118 Work correctly if read is interrupted.
119 (grepfile): Work correctly if open or close is interrupted.
120
121 * src/system.h (SEEK_SET, SEEK_CUR): New macros.
122
1231999-10-02 Alain Magloire
124
125 * src/regex.[ch]: upgrade from GNU lib C source tree.
126
127 * make beta 2.3f available.
128
1291999-10-02 Paul Eggert
130
131 * NEWS: egrep is now equivalent to `grep -E'.
132 The lower bound of an interval is not optional.
133 You can specify a matcher multiple types without error.
134 -u and -U are now allowed on non-DOS hosts, and have no effect.
135 * doc/grep.texi: Likewise.
136 * doc/grep.1: Likewise.
137 Fix some troff bugs that prevented `groff' from rendering the page.
138
139 * src/egrepmat.c, src/fgrepmat.c, src/grepmat.c (default_matcher):
140 Remove.
141 (matcher): Add.
142 * src/grep.h (default_matcher): Remove.
143 (matcher): Now exported from ?grepmat.c, not grep.c.
144
145 * src/dfa.c (lex): If { would start an invalid interval specification,
146 treat it as a normal character.
147 Remove (broken) support for {,M} meaning {0,M}.
148 Diagnose bogus intervals like {1,0}.
149 (closure): maxrep is now -1 to indicate no limit, not zero;
150 zero is a valid value for maxrep, meaning an upper bound of zero.
151
152 * src/grep.c (short_options): New constant.
153 (long_options, main): -u and -U are now supported on Unix,
154 with no effect.
155 (matcher): Removed; now defined by ?grepmat.c.
156 (install_matcher): Renamed from setmatcher.
157 (setmatcher): New function.
158 (usage): Report new, more uniform option scheme.
159 (main): Do not initialize matcher; ?grepmat.c now does this.
160 Rely on setmatcher to catch matcher conflicts.
161 Default matcher is "grep".
162
163 * src/search.c (matchers):
164 Remove "posix-egrep" matcher; no longer needed.
165 (Ecompile): Likewise.
166 The egrep matcher now has POSIX behavior.
167
168 * tests/bre.tests: grep '\{' is no longer an error.
169 Fix test for interval too large, and enable it.
170 * tests/ere.tests: grep -E {1 is no longer an error
171 Likewise for a{1, a{1a, a{1a}, a{1,x}.
172
1731999-09-22 Paul Eggert
174
175 * largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around GCC
176 2.95.1 bug with HP-UX 10.20.
177
1781999-09-12 Paul Eggert
179
180 * src/grep.c (fillbuf): Fix typo: we sometimes reported
181 arithmetic overflow even when there wasn't any.
182
1831999-09-12 Paul Eggert
184
185 * configure.in (AC_CHECK_FUNCS): Add memmove.
186
187 * src/system.h (S_ISREG): New macro.
188 (memmove): Define if ! defined HAVE_MEMMOVE && ! defined memmove,
189 not if !defined STDC_HEADERS. This is needed for SunOS 4.1.4,
190 which defines STDC_HEADERS but lacks memmove.
191
192 * src/grep.c (bufoffset): Needed even if !defined HAVE_MMAP.
193 (reset): Always fstat the file, since we always need its size if it is
194 regular.
195 Similarly, get the buffer offset of every regular file.
196 Set bufmapped to 0 if the file's initial offset is not a multiple
197 of the page size.
198 (fillbuf): Calculate an upper bound on how much memory we should
199 allocate only for regular files, since we don't know the sizes of
200 other files.
201 Don't bother to check whether the file offset is a multiple of the page
202 size, since we now do that just once in `reset'.
203 When an mmapped area would fall past the end of the file, trim it to
204 just before instead of giving up immediately and doing a `read';
205 that avoids a worst-case behavior that could read half an mmapped file.
206 Fix bug when computing offsets on hosts that don't have mmap.
207
2081999-08-27 Paul Eggert
209
210 * src/system.h (memmove): New macro.
211
212 * src/grep.c (page_alloc): Reallocate the old buffer instead
213 of having both old and new buffers active simultaneously.
214 Remove valloc debugging variant, which no longer applies.
215
216 (fillbuf): Rejigger the buffer allocation mechanism. The old
217 mechanism could allocate more than 10*N bytes for an N-byte
218 file, which was excessive. Check for arithmetic overflow a
219 bit more carefully.
220
2211999-08-25 Paul Eggert
222
223 * src/grep.c (grepdir):
224 Don't assume that st_ino and st_dev must be integers;
225 POSIX.1 allows them to be floating-point (!).
226
227 * src/vms_fab.h (arr_ptr): `:' -> `;' to fix typo.
228
2291999-08-18 Alain Magloire
230
231 * 2.3e snapshot.
232
2331999-08-18 Alain Magloire
234
235 * src/search.c: On a CRAY J90 system running UNICOS 8.0.
236 Compilation of ./src/search.c failed because the declaration of
237 the variable "regex":
238 static struct re_pattern_buffer regex;
239 conflicted with a previous declaration search.c #includes "system.h",
240 which #includes <stdlib.h>, which declares :
241 extern char *regex __((char *_Re, char *_Subject, ...));
242 The declaration in search.c is local to that one source file.
243 I just changed its name to something less likely to conflict.
244 (I called it "regexbuf", but you could pick any name you want.)
245 Excerpt email from Dean Kopesky.
246
2471999-08-16 Paul Eggert
248
249 Upgrade large-file support to the version used in tar and
250 textutils.
251
252 * Makefile.am (ACLOCAL_AMFLAGS): Define to be empty.
253 (M4DIR, ACINCLUDE_INPUTS): New macros.
254 ($(srcdir)/acinclude.m4): New rule.
255
256 * configure.in (AC_CANONICAL_HOST, AM_C_PROTOTYPES): Add.
257 (AC_SYS_LARGEFILE): Renamed from AC_LFS, for compatibility
258 with what should appear in the next autoconf release.
259
260 * m4/largefile.m4: Renamed from m4/lfs.m4.
261
262 * src/ansi2knr.1, src/ansi2knr.c, config.guess, config.sub:
263 New files. config.guess and config.sub ar needed by the new
264 AC_SYS_LARGEFILE. ansi2knr is needed by AM_C_PROTOTYPES,
265 which in turn is needed by the new AC_SYS_LARGEFILE.
266
2671999-08-16 Alain Magloire
268
269 * 2.3d snapshot on ftp server.
270
2711999-07-26 Paul Eggert
272
273Several GNU tools have options to process arbitrary file names, even
274file names that contain newline characters. These include `find
275-print0', `perl -0', `sort -z', and `xargs -0'. It'd be handy if GNU
276grep also processed such file names. Here's a proposed patch to do
277this, relative to grep 2.3c. This patch introduces two options, one
278for the data, and one for the file names. (Sometimes one wants
279null-terminated file names in the output, and sometimes one wants to
280process lists of null-terminated strings, and these are orthogonal
281axes.)
282
283 * NEWS, doc/grep.texi: New -z or --null-data and -Z or --null options.
284 * src/grep.c (long_options, usage, main): Likewise.
285
286 * src/dfa.h (dfasyntax): New eol parameter.
287 * src/dfa.c (eolbyte): New var.
288 (dfasyntax): Set it from new parameter.
289 (lex, dfastat, build_state, dfaexec): Use it instead of '\n'.
290
291 * src/grep.h (eolbyte): New decl.
292 * src/grep.c (eolbyte): New var.
293 (nlscan, prpending, prtext, grepbuf, grep): Use it instead of '\n'.
294 (filename_mask): New var.
295 (prline, grepfile): Output NUL separator if filename_mask is zero.
296 (grep): Look for '\200' as the hallmark of a binary file, not '\0',
297 if -z or --null-data is specified, since it implies that '\0' is
298 expected as text.
299
300 * src/search.c (Gcompile, Ecompile): Pass eolbyte to dfasyntax.
301 (EGexecute, Fexecute): Use eolbyte instead of '\n'.
302
3031999-06-15 Alain Magloire
304
305 * src/grep.c, doc/grep{1,texi} :
306 --revert-match should be --invert-match.
307 Correction proposed by Karl Berry.
308
3091999-06-12 Alain Magloire
310
311 * doc/grep.{1,texi}: add description for --with-filename.
312 Noted missing by UEBAYASHI Masao.
313
3141999-03-17 Paul Eggert
315
316 * NEWS: Add GREP_OPTIONS.
317
318 * doc/grep.texi: Document GREP_OPTIONS, and the other
319 environment variables. Fix doc for [:blank:], [:cntrl:], [:punct:].
320
321 * src/grep.c (prepend_args, prepend_default_options): New functions.
322 (main): Use them to implement GREP_OPTIONS.
323 * src/system.h (getenv): New decl.
324
3251999-03-16 Volker Borchert
326
327 * configure.in: Use case case ... esac for checking Visual C++.
328 When ${CC} contains options it was not recognize.
329
3301999-03-07 Paul Eggert
331
332 * src/grep.c (usage): Don't report -E, -F, and -G unless we're grep.
333 (main): Don't match options -E, -F, and -G unless we're grep.
334 Remove after-the-fact check for options -E, -F, and -G, since
335 they're no longer needed.
336
3371999-03-05 Eli Zaretskii
338
339 * src/grep.c (main): Print the name of the default matcher instead
340 of just "grep".
341
3421999-02-06 Alain Magloire
343
344 * tests/*.awk : Linux users are seeing "Broken Pipe" on make check.
345 The problem is that grep does not drain its stdin, thus the previous
346 process in the pipeline receives a SIGPIPE. Other shells are silent
347 about this. There is actually no failure, since the broken pipe is
348 expected. You can work around it by changing the pipeline, so that
349 the input is drained, like this:
350 status=`echo 'check' | { ${GREP} -E -e pattern >/dev/null 2>&1;
351 echo $?; cat >/dev/null; }`; if test $status -ne $errnu then ... fi
352 Excerpt email from Andreas Schwab.
353
3541999-02-23 Alain Magloire
355
356 * src/grep.c : Restrict the use of -E, -F, -G
357 to only grep driver, Posix behaviour. {f,e}grep
358 the matcher is already set. This change may brake
359 scripts, warn in NEWS.
360
361 * doc/grep.{1,texi} : -C takes arguments, upgrade manual.
362
363 * beta 2.3a
364
3651999-02-23 Alain Magloire
366
367 * configure.in : Change the configure VC test from
368 'test x$ac_cv_prog_CC = xcl;' to 'test x"$ac_cv_prog_CC" = xcl;'
369 Email from Joshua R. Poulson.
370
3711999-02-23 Paul Eggert
372
373 Fix porting bug reported by Amakawa Shuhei for SunOS 4.1.4-JL.
374 The btowc.c shipped with grep 2.3 is incorrect for Solaris
375 2.5.1 and earlier, as it assumes UTF8, which these OSes do not
376 support. Solaris 7 supports btowc, so there's no need to ship
377 a substitute for it. The only questionable case is Solaris
378 2.6, which lacks btowc but does support UTF8. However, 2.6
379 supports UTF8 but only as a demonstration (for an English
380 locale!); Japanese Solaris 2.6 users typically use EUC, or
381 sometimes shift-JIS, but they cannot use UTF8 since Japanese
382 UTF8 is not supported. Hence there's no point to having grep
383 substitute a btowc that uses UTF8, as it is either redundant,
384 or it will almost invariably have incorrect behavior.
385
386 * configure.in (AC_CHECK_HEADERS): Don't set USE_WCHAR.
387 (AC_CHECK_FUNCS): Add btowc, wctype.
388 (AC_REPLACE_FUNCS): Don't replace btowc; our replacement is
389 invariably doing the wrong thing anyway, at least on SunOS/Solaris.
390 Don't bother to check for wctype in -lw, as we don't support
391 wide characters on Solaris 2.5.1 or earlier anyway.
392
393 * bootstrap/Makefile.try (OBJS): Remove btowc.$(OBJEXT).
394
395 * src/btowc.c: Removed; no longer needed.
396
3971999-02-19 Paul Eggert
398
399 * NEWS: Fix typo when talking about the old behavior of
400 silently skipping directories; it was grep 2.1, not grep 2.2.
401
4021999-02-15 Alain Magloire
403
404 * bootstrap/Makefile.try : add DJGPP DEFS.
405 Done by Elie Zaretsckii.
