ChangeLog revision 55360
11999-11-18 Paul Eggert 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. 406 4071999-02-14 Alain Magloire 408 409 * m4/gettext.m4 : Guard [] with changequote. 410 From Elie Zaretskii. 411 412 * djgpp/config.bat : Makefile.in.in --> Makefile.in-in 413 From Elie Zaretskii. 414 415 * src/dosbuf: k&r function parameter. 416 417 * release of 2.3. 418 4191999-02-10 Alain Magloire 420 421 * bootstrap/{Makefile{try,am},REAMDE} : skeleton 422 provided for system lacking the tools to autoconfigure. 423 424 * src/{e,f,}grepmat.c: added guard [HAVE_CONFIG_H] 425 4261999-02-10 Alain Magloire 427 428 * PATCHES-AC, PATCHES-AM: updated. 429 430 * m4/regex.m4 : updated. 431 4321999-02-05 Eli Zaretskii 433 434 * m4/gettext.m4 : Support DOS-style D:/foo/bar absolute file 435 names. 436 437 * aclocal.m4 (DJGPP) : Use $DJ_GPP instead, since changing the 438 latter prevents GCC from finding headers and libraries. 439 440 * djgpp/config.bat: Make building from another directory work 441 442 * djgpp/config.sed: Remove redundant command wich edited path 443 separator: now done by configure. 444 445 * src/grep.c [O_BINARY]: Add prototype for undossify_input. 446 447 * doc/grep.texi (Introduction): Typo fixed. 448 4491999-02-03 Alain Magloire 450 451 * grep-2.2f beta release. 452 4531999-02-02 Alain Magloire 454 455 * m4/{djgpp,envsep,glibc,regex,dosfile,isc-posix}.m4 : 456 New files to aid configuration and unload configure.in. 457 * m4/Makefile.am : updated. 458 * src/btowc.c : protect for wchar.h 459 4601999-01-28 Alain Magloire 461 462 * intl/Makefile.in: Replace .o with .${ac_objext} where necessary. 463 Work around a limitation of Visual C++ on Cygwin32. 464 * acconfig.h configure.in: Define `alloca' as `_alloca' when CC=cl. 465 This little hack was suggested by Ian Roxborough <irox@cygnus.com>. 466 Patch forwarded by Ben Elliston. 467 4681999-01-28 Alain Magloire 469 470 * PATCHES-AM: New file. A small patch for automake-1.4, use $(sep) 471 as the path separator base on @SEP@. 472 * PATCHES-AC configure.in : updated for autoconf-13. 473 4741999-01-27 Volker Borchert 475 476 * grep.c: fgrep -NUM not working correctly. 477 add the argument number to digit_args_val. 478 4791999-01-22 Paul Eggert 480 481 Prevent grep -r from recursing infinitely through directory loops via 482 symbolic links. 483 484 * grep.c (struct stats): New type. 485 (stats_base): New var. 486 (bufstat): Remove; subsumed by stats->stat. 487 (reset, fillbuf, grep, grepdir, grepfile): Pass struct stats * arg, 488 for directory loop checking; use this instead of the bufstat global. 489 All callers changed. 490 (grepfile): Stat the file before invoking grepdir. 491 (grepdir): Assume that the argument has already been statted. 492 No longer a need for a directory size argument, since it 493 can be gotten from the struct stats * argument. 494 Check for directory loops. 495 Create linked list of directories currently being visited, 496 to detect loops. 497 4981998-12-29 Kaveh R. Ghazi 499 500 intl/localealias.c: When building grep-2.2e using cc on Irix4, 501 I needed the following patch to intl/localealias.c. 502 (Its the same patch used by fileutils-4.0.) The patch resolves 503 conflicts between char* and unsigned char* in the i18n code. 504 5051998-12-10 Alain Magloire 506 507 * src/grep.c : Typo in contex -->context 508 Noted by Vladimir Michl. 509 5101998-12-01 Alain Magloire 511 512 * doc/Makefile.am djgpp/Makefile.am m4/Makefile.am vms/Makefile.am: 513 New files. 514 515 * m4/progtest.m4: proctect '[]' from m4. 516 Noted by Eli Z. 517 518 * PATCHES-AC: New file, add the patch for autoconf in the dist. 519 520 * acconfig.h: (HAVE_DOS_FILENAME) 521 522 * TODO: updated. 523 524 * src/search.c: remove obsolete 'gegrep,ggrep,gnugrep' 525 matchers. grep no longer depend on argv[0]. 526 527 * grep-2.2e beta to test DJGPP port. 528 5291998-11-28 Paul Eggert 530 531 Various portability enhancements: 532 - Don't assume that O_BINARY implies DOS. Use separate 533 macros D_OK (for DOS-like directory access) and 534 HAVE_DOS_FILE_NAMES (for DOS-like file names). 535 - Don't assume that off_t fits into long; it doesn't on Solaris 2.6. 536 - Have is_EISDIR set errno properly on hosts with screwed-up EISDIR. 537 - Treat ':' specially in DOS file names only if it's the end of a 538 drive specifier. 539 - Protect against errno < 0. 540 541 * src/grep.c (is_EISDIR): Move defn to system.h. 542 (print_offset_sep): New function. 543 (fillbuf): Remove redundant test of O_BINARY. 544 (totalcc, totalnl): Now of type off_t. 545 (prline): Use print_offset_sep to print file offsets. 546 (grepfile): Don't set e to EISDIR; that's is_EISDIR's responsibility 547 on machines that don't work properly with EISDIR. 548 (grepdir): Don't assume ':' means slash on all DOS filenames; 549 it means it only in the file prefix. 550 551 * src/system.h (strerror): Check for negative error numbers. 552 (is_EISDIR): Depend on D_OK, not O_BINARY. 553 (SET_BINARY): Depend on HAVE_SETMODE, not __DJGPP__. 554 (IS_SLASH, FILESYSTEM_PREFIX_LEN): Depend on HAVE_DOS_FILE_NAMES, 555 not O_BINARY. 556 (CHAR_BIT): New macro. 557 558 * src/dosbuf.c (struct dos_map): 559 pos and add members are now of type off_t. 560 (dos_stripped_crs): Now of type off_t. 561 (dossified_pos): Now accepts arg and returns value of type off_t. 562 563 * configure.in (AC_CHECK_FUNCS): Add setmode. 564 (HAVE_DOS_FILENAMES): New macro 565 5661998-11-27 Eli Zaretskii 567 568 * djgpp/config.sed: New file, a Sed script to edit configure 569 script before running it on DOS/Windows. 570 * djgpp/config.bat: Updated to handle po2tbl.sed.in and 571 po/Makefile.in.in on DOS filesystems, and to run config.sed. 572 5731998-11-24 Jim Meyering 574 575 * src/grep.c : Typo s/infalid/invalid/ 576 Also noted by Stanislav Brabec. 577 5781998-11-24 Eli Zaretskii 579 580 * doc/grep.texi: I found and corrected several typos. 581 I believe the GNU standards require the section that describes the 582 options to the programs to be called ``Invoking'' or ``Invoking 583 <program-name>''. This is so users and programs can easily find 584 that node in any Info file. So I changed the name of the 585 `Options' chapter to `Invoking', and corrected the 586 cross-references accordingly. 587 I added some markup to things like file names and options. 588 I added some additional index entries where that seemed useful. 589 I also corrected some index entries, such as "@cindex [:alnum:]", 590 which used a colon in them (the colons confuse Info readers). 591 5921998-11-24 Alain Magloire 593 594 * grep/doc/grep.texi : -h is not use for help. 595 Nit spotted by Jim Meyering. 596 5971998-11-23 Alain Magloire 598 599 * doc: New directory, grep.1, {e,f}grep.man move here 600 * doc/grep.texi: New info manual 601 * doc/version.texi: New 602 * doc/Makefile.am: New 603 * tests/{ere,bre}.*: New files.

Brisco. 670 671 * vms/make.com : add line to compile vms_fab.c and 672 {e,f,}grepmat.c with link for each grep/fgrep/egrep. 673 Base on patch send by Phillib C. Brisco. 674 6751998-11-09 Alain Magloire 676 677 * grep-2.2c on alpha for testing. 678 6791998-11-09 Paul Eggert 680 681 * src/grep.1: Fix `Last Change' of output by generating the date 682 from the RCS Id. 683 684 * src/grep.c (is_EISDIR): New macro. 685 (grep): If -s, suppress errors from trying to read directories. 686 (grepfile): Use is_EISDIR to simplify code. 687 (grepdir): If -s, suppress errors from trying to read directories. 688 689 * src/grep.1: Fix -q -r -s problems; describe BSD grep better. 690 691 * src/grep.c (main): Update copyright. 692 693 Specify default matcher with default_matcher extern var, not 694 DEFAULT_MATCHER macro. This is more straightforward and means 695 we need to compile grep.c just once. 696 697 * src/egrepmat.c, src/fgrepmat.c, src/grepmat.c: New files. 698 699 * src/Makefile.am (base_sources): New macro. 700 (egrep_SOURCES, fgrep_SOURCES, grep_SOURCES): Now consist of 701 $(base_sources) plus the single tailoring file. 702 (grep_LDADD, egrep_LDADD, fgrep_LDADD): Remove. 703 (EXTRA_DIST): Remove grep.c, regex.c. 704 (fgrep.o, egrep.o): Remove. 705 706 * src/grep.h (matcher): Now char const *. 707 (default_matcher): New decl. 708 709 * src/grep.c (matcher): Now char const *. 710 (setmatcher): Now accepts char const *. 711 (main): Default the matcher from default_matcher (linked externally) 712 rather than DEFAULT_MATCHER (a macro). 713 7141998-11-08 Alain Magloire 715 716 * src/grep.1: `prep.ai.mit.edu' should be replaced with `gnu.org'. 717 Nit from Paul Eggert. 718 7191998-11-06 Alain Magloire 720 721 * src/grep.c: The Matcher is not set to argv[0] but 722 explicitly by a #define MATCHER at compile time default is "grep". 723 724 * aclocal/: NEW dir. provides our own *.m4 725 726 * configure.in: Move Paul's Large Files to AC_LFS.(aclocal/lfs.m4) 727 Taken from Jim Meyering fileutils. 728 7291998-11-05 Alain Magloire 730 731 * src/grep.1: update the man pages according to the 732 changes make by Miles. 733 734 * po/*.po: updated. 735 736 * first beta release for 2.3 (2.2a). 737 7381998-11-04 Miles Bader 739 740 * src/grep.c (main): Rationalize interaction of -C/-NUM/-A/-B 741 options, and allow -C to have an optional argument. -NUM can 742 now be mixed with -C, and -A, -B always take precedence over 743 -C/-NUM, regardless of order. 744 (long_options): Let -C/--context take an optional argument. 745 7461998-11-03 Alain Magloire 747 748 * src/dfa.c: HP-UX define clrbit/setbit as macros in <sys/param.h> 749 #undef if defined. 750 Fixed by Andreas Ley and Philippe Defert. 751 752 * src/grep.1 : mention that -s follows POSIX.2 behavior. 753 Noted by Paul Eggert and others. 754 755 * tests/khadafy.sh: a typo in failure(s). 756 Spotted By Sotiris Vassilopoulos. 757 7581998-11-01 Paul Eggert 759 760 * src/system.h (IN_CTYPE_DOMAIN): New macro. 761 (ISALPHA, ISUPPER, ISLOWER, ISDIGIT, ISXDIGIT, ISSPACE, 762 ISPUNCT, ISALNUM, ISPRINT, ISGRAPH, ISCNTRL): Use 763 IN_CTYPE_DOMAIN instead of isascii. 764 7651998-08-18 Paul Eggert 766 767 Add support for new -r or --recursive (or -d recurse or 768 --directories=recurse) option. 769 770 * src/Makefile.am (grep_SOURCES): Add savedir.c, savedir.h, stpcpy.c. 771 772 * src/grep.1: Describe new options. 773 774 * src/grep.c: Include "savedir.h". 775 (long_options): Add -r or --recursive. 776 (RECURSE_DIRECTORIES): New enum value. 777 (IS_DIRECTORY_ERRNO): Remove. 778 (reset, grep): Add file name arg. 779 (grepdir, grepfile): New functions. 780 (initial_bufoffset): New var. 781 (reset): Initialize it. 782 (fillbuf): Use it. 783 (count_matches, list_files, no_filenames, suppress_errors): New static 784 vars; formerly were local to `main'. 785 (grep): Recurse through directories if the user asks for this. 786 (usage, main): Add new options. 787 (main): Change some local vars to be static, as described above. 788 Move most of the guts into grepfile function. 789 so that it can be recursed through. 790 791 * configure.in (AC_HEADER_DIRENT, AC_FUNC_CLOSEDIR_VOID): Add. 792 (AC_REPLACE_FUNCS): Add stpcpy. 793 794 * src/savedir.c, src/savedir.h, src/stpcpy.c: New files; 795 taken from fileutils 3.16u. 796 7971998-08-11 Paul Eggert 798 799 * src/system.h (initialize_main): New macro. 800 * src/grep.c (main): Invoke initialize_main first thing. 801 8021998-04-29 Paul Eggert 803 804 * NEWS, src/grep.1: Describe new -a and -d options. 805 806 * src/grep.c (long_options, usage, main): 807 New options -d or --directories and -a or --text. 808 (directories, always_text): New variables. 809 (IS_DIRECTORY_ERRNO): New macro. 810 (reset): Now returns value specifying whether to skip this file. 811 Stat the file if either mmap or directory-skipping is possible. 812 Skip the file if it's a directory and we're skipping directories. 813 (grep): Skip the file if `reset' tells us to. 814 (main): If open fails because the file is a directory, and if we're 815 skipping directories, don't report an error. 816 Remove special case for DOS and Windows. 817 818 * src/dosbuf.c (guess_type): Use the same method for guessing whether a 819 file is binary as grep.c's grep does. 820 There's no longer any need to declare `bp' to be unsigned. 821 8221998-04-26 Alain Magloire 823 824 * grep-2.2 release. 825 826 * src/dfa.c: Wrong revision was pulled out 827 for beta 2.1.1d. 828 * src/search.c: Wrong revision was pulled out 829 for beta 2.1.1d. 830 831 * src/grep.c: ck_atoi () added instead of atoi (). 832 Suggestion from Jim Meyering. 833 ck_atoi () pulled from diffutils-2.7, maintained by Paul Eggert. 834 835 * AUTHORS: Rephrase of some sentences. 836 * README: Rewording. 837 Noted and patched by Joel N. Weber II. 838 8391998-04-17 Kaveh R. Ghazi 840 841 * src/dfa.h: Don't define `const', trust autoconf to handle it. 842 8431998-04-16 Alain Magloire 844 845 * tests/{status,empty}.sh: wrong return status. 846 847 * src/grep.c: Remove the REGEX part in usage (), it was 848 consider overkill by most. 849 8501998-04-14 Eli Zaretskii 851 852 * djgpp/config.bat: Support file names with multiple dots on all 853 platforms. 854 855 * djgpp/README: Add instructions about file names illegal on 856 MS-DOS. 857 8581998-04-13 Alain Magloire 859 860 * src/dfa.c: by "popular" demand reverse 861 back to '_' not word-constituent. 862 863 * grep-2.1.1c available for testing. 864 8651998-04-13 Karl Heuer 866 867 * src/grep.c: (a) The directory check is done too early: 868 logically, if the argument is "-", then it refers to standard 869 input, regardless of whether there's something in the file 870 system answering to "-". 871 (b) The sh command "grep -l root /etc/passwd /etc/group 0<&-" 872 prints "(standard input)" instead of "/etc/passwd", because it 873 mistakenly believes that a named file will never be opened on fd 874 0. The string "(standard input)" should be based on the file 875 having been originally specified as "-", rather than making 876 assumptions about the fd. 877 (c) the code that calls close(fd) is being done outside of the 878 test for a bad fd. Thus, if the open failed, this code will 879 attempt to close(-1). It should be done inside the "fd != -1" 880 branch. 881 This patch addresses all three of these problems. 882 8831998-04-13 Alain Magloire 884 885 * configure.in: remove the deprecated AC_ISC_POSIX macro. 886 Spotted by Karl Heuer. 887 8881998-04-03 Eli Zaretskii 889 890 * djgpp/main.mak, djgpp/src.mak, djgpp/tests.mak: Updated from the 891 relevant Makefile.in files. 892 893 * djgpp/config.bat: Create files in intl directory like the 894 configure script does. 895 8961998-03-28 Eli Zaretskii 897 898 * djgpp/main.mak, djgpp/src.mak, djgpp/tests.mak: Updated to track 899 changes in respective Makefile.in files. 900 901 * src/dosbuf.c (guess_type): Avoid running off the end of the 902 buffer. Spotted by Paul Eggert. 903 9041998-03-27 Alain Magloire 905 906 * grep-2.1.1b.tar.gz available. 907 908 * src/regex.c: CLASS_CHAR_MAX set to 256 instead of 6 909 when WCTYPE and WCHAR are not defined. When class names 910 where bigger then 6, it will not detect an error. 911 example '[[:alphabet:]]'. 912 913 * Updated the copyright of the files with emacs. 914 With emacs Jim :). 915 9161998-03-26 Jim Meyering 917 918 * src/dfa.c (IS_WORD_CONSTITUENT): Define. 919 (lex): Use IS_WORD_CONSTITUENT, not ISALNUM. 920 Don't special-case '_'. 921 (dfastate): Use IS_WORD_CONSTITUENT, not ISALNUM. 922 (dfaexec): Likewise. 923 9241998-03-25 Alain Magloire 925 926 * tests/warning.sh: typos and replace the echos with 927 a simple cat. 928 Noted By Jim Meyering. 929 930 * src/regex.c: #undef ISASCII and ISPRINT before defining 931 them(On Solaris it was define). 932 Pattern 'a[[:]:]]b' is an invalid char class and the error 933 from regex was 1(REG_NOMATCH) instead of 2 (REG_ECTYPE). 934 Fix with help from Ulrich Drepper. 935 936 * src/grep.c (usage): Ulrich wrote: "A single printf should 937 not have more than 900 bytes. For translation reasons the 938 text shouldn't be split in too many pieces since this is 939 tiresome and also does not help to generate a consistent picture." 940 Noted by Ulrich Drepper. 941 * src/grep.c (usage): Dig out and old patch from 942 Franc,ois to explain the regex in usage(). 943 Ideas from Franc,ois Pinard. 944 9451998-03-23 Alain Magloire 946 947 * testing: grep-2.1.1a for testing. 948 949 * configure.in: Solaris needs '-lw' if we use wchar/wctype 950 functions. 951 * src/btowc.c: New file from GNU libc. Solaris 2.5 don't 952 have it define. 953 * configure.in : check for btowc (). 954 955 * regex.c: Include <wchar.h> before <wctype.h>, to work around 956 a Solaris 2.5 bug. 957 Patch provided by Paul Eggert. 958 959 * tests/status.sh: new file to check return status code. 960 * tests/empty.sh: new file to check for empty pattern. 961 * tests/warning.sh: new file to tell where to report errors. 962 963 * configure.in: If available, prefer support for large files 964 unless the user specified one of the CPPFLAGS, LDFLAGS, or LIBS 965 variables. 966 Done by Paul Eggert. 967 968 * src/grep.c (usage): change prep.ai.mit.edu for gnu.org. 969 9701998-03-18 Alain Magloire 971 972 * src/grep.c (usage): Formating the --help message a bit off. 973 Noted by William Bader. 974 975 * src/grep.c (main): When checking conflicting matcher for option -E the 976 matcher was to "egrep" instead of "posix-egrep". 977 Reported by kwzh@gnu.org. 978 979 * src/grep.c: Typos and rewording the --help message. 980 Reported by Karl Heuer. 981 982 * src/grep.1: The man page wording : 983 A regular expression matching a single character may be 984 followed by one of several repetition operators: 985 is unclear since 'x(yz)*z' is a valid regex. 986 Remove the "matching a single character". 987 Suggested by Harald Hanche-Olsen. 988 989 * src/grep.c (main): `-f /dev/null' now specifies no patterns 990 and therfore matches nothing. 991 Reported by Jorge Stolfi. 992 Patched by Paul Eggert. 993 9941998-03-10 Alain Magloire 995 996 * Ice storm 98(el nino).

It is useful sometimes to make a link to a utility with 1172 a different name, and that should not change what it does." 1173 For now egrep and fgrep will be copies of grep. A better scheme 1174 should be found later. 1175 After discussion with Tom Tromey <tromey@cygnus.com>. 1176 1177 * fgrep.man and egrep.man included: They are stubs that call grep.1. 1178 * Makefile.am: modified to install {f,e,}grep[,.1]. 1179 1180 * speed hack for -l, -L: bail out on first match. 1181 From Scott Weikart <scott@igc.apc.org>. 1182 1183 * *.[ch]: provided prototypes for strict argument checking 1184 With the help of Stewart Levin <stew@sep.stanford.edu>. 1185 11861997-07-16 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1187 1188 * configure.in: typo in the creation of po/Makefile 1189 Noted by Volker Borchert bt@teknon.de. 1190 1191 * grep-2.0b: make it available for testing. 1192 11931997-07-15 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1194 1195 * src/grep.c usage(): cut the --help in smaller printf()'s 1196 Noted by Ulrich Drepper <drepper@cygnus.com>. 1197 11981997-07-14 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1199 1200 * grep-2.0a: make an alpha available for testing. 1201 12021997-07-12 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1203 1204 * run gettextize: added the po directory filled with *.po files. 1205 1206 * check.sh, scriptgen.awk: fix grep paths. 1207 1208 * change the directory strucure: grep is now in src to comply with 1209 gettext.m4. 1210 1211 * grep.c version.c [VERSION]: got rid of version.c, 1212 it is now define via config.h. 1213 1214 * dfa.c: patch to speed up initialization. 1215 Arnold Robbins (arnold@gnu.ai.mit.edu). 1216 12171997-07-09 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1218 1219 * *.c [HAVE_CONFIG_H]: Macro defined. 1220 1221 * support for I18N in Makefile.am and configure.in. 1222 1223 * update all the string to use gettext(I18N). 1224 Help from Franc,ois Pinard previous patch <pinard@IRO.UMontreal.CA>. 1225 12261997-07-04 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1227 1228 * obstack.[ch]: updated from glibc. 1229 Work of Ulrich Drepper <drepper@cygnus.com>. 1230 1231 * regex.[ch]: updated from glibc. 1232 Work of Ulrich Drepper <drepper@cygnus.com>. 1233 1234 * grep.c: for option -e not counting '\n' for new keys. 1235 From Mark Waite <markw@mddmew.fc.hp.com>. 1236 1237 * grep.c: for option -f allocating the right count. 1238 From Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>. 1239 Mike Heartel (mike@cs.uoregon.edu). 1240 1241 * kwset.c (bmexec): Cast tp[-2] to unsigned char before comparing. 1242 From Jim Meyering <meyering@asic.sc.ti.com>. 1243 1244 * grep.1: various typos. 1245 From Keith Bostic <bostic@bsdi.com>. 1246 Mike Heartel (mike@cs.uoregon.edu). 1247 12481997-06-17 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1249 1250 * grep.c: support for long options. 1251 patch done by Franc,ois Pinard <pinard@IRO.UMontreal.CA>. 1252 1253 * add getopt1.c in Makefile.am. 1254 Noted by Franc,ois Pinard <pinard@IRO.UMontreal.CA> 1255 1256 * replace getopt.[ch] and add getopt1.c. 1257 1258 * kwset.c: undef malloc before define it. 1259 Franc,ois Pinard <pinard@IRO.UMontreal.CA>. 1260 12611997-06-07 Alain Magloire <alainm@rcsm.ee.mcgill.ca> 1262 1263 * grep.c: format incorrect in 1264 fprintf("%s: warning: %s: %s...", filename, strerror(errno)). 1265 Mike Heartel (mike@cs.uoregon.edu). 1266 12671996-11-19 David J MacKenzie <djm@catapult.va.pubnix.com> 1268 1269 * make.com: Set the logical SYS.
