Well, if an off_t is larger than an int, 129 the value gets truncated. This would not normally have an effect on a 130 little-endian platform (unless the file is >2GB), but on a big-endian 131 system it will always fail. The external effect is that 132 "grep -r foo dir_name" fails with ENOMEM (from malloc() within 133 savedir()). 134 135 * grep/src/grep.c (grepdir): Remove the (unsigned) cast when calling 136 savedir(). 137 Patch from David Clissold. 138 1392001-07-29 Alain Magloire 140 141 * grep/doc/grep.texi: In Bugs report use {n,m} for consistency. 142 * grep/doc/grep.1: Likewised. 143 Noted by Steven Lucy. 144 1452001-04-27 Isamu Hasegawa 146 147 * dfa.c (mblen_buf) : New variable contains the amount of remain 148 byte of corresponding multibyte character in the input string. 149 (SKIP_REMAIN_MB_IF_INITIAL_STATE) : Use mblen_buf. 150 (match_anychar) : Use mblen_buf. 151 (match_mb_charset) : Use mblen_buf. 152 (transit_state_consume_1char) : Use mblen_buf. 153 (transit_state) : Use inputwcs to get current (multibyte) character. 154 (dfaexec) : Add initialization of mblen_buf. 155 1562001-04-27 Isamu Hasegawa 157 158 * dfa.c (addtok) : Set appropriate value to multibyte_prop. 159 (dfastate) : Add the initialization of the variable. 160 (dfaexec) : Call transit_state if d->fail may transit by 161 multibyte characters. 162 (transit_state_singlebyte) : Clean up unnecessary code. 163 (transit_state_consume_1char) : Likewise. 164 (transit_state) : Add checking for word and newline. 165 1662001-04-19 Isamu Hasegawa 167 168 * search.c (check_multibyte_string) : Check the case when mbclen == 0. 169 1702001-04-11 Isamu Hasegawa 171 172 * search.c (check_multibyte_string) : Check the head of multibyte 173 characters, and optimize a bit. 174 (EGexecute) : Optimize a bit. 175 (Fexecute) : Fix the index. 176 1772001-04-02 Alain Magloire 178 179 * lib/regex.c: Update from GNU lib C, with the changes 180 provided by Paul Eggert. 181 * lib/posix/regex.h: Likewise. 182 1832001-02-17 Paul Eggert 184 185 Stop trying to support hosts that have nonstandard declarations for 186 mbrtowc and/or mbstate_t. It's not worth the portability hassle. 187 188 * lib/quotearg.c (mbrtowc, mbsinit): Remove workaround macros 189 for hosts that have mbrtowc but not mbstate_t, as we now 190 insist on proper declarations for both before using mbrtowc. 191 1922001-03-18 Alain Magloire 193 194 * configure.in: Call AC_MBSTATE_T. 195 * Makefile.am: Add mbstate_t.m4 196 * m4/Makefile.am: Add mbstate_t.m4 197 * m4/mbstate_t.m4: New m4 macro. 198 * lib/strtol.c: Define CHAR_BITS. 199 Uwe H. Steinfeld, Ruslan Ermilov, Volkert Bochert, noted 200 that mbstate_t was not define for certain platforms. 201 2022001-03-18 Paul Eggert 203 204 * src/grep.c (fillbuf): Fix storage allocation performance 205 bug: buffer was doubling in size in many cases where it didn't 206 have to. 207 2082001-03-17 Paul Eggert 209 210 * src/grep.c (fillbuf): Avoid unnecessary division by 2. 211 Don't check xrealloc return value; it's guaranteed to be nonzero. 212 (fillbuf, grepdir): Use xalloc_die rather than error; it's shorter. 213 2142001-03-17 Alain Magloire 215 216 * src/grep.c (context_length_arg): error () passing wrong format. 217 Spotted by Jim Meyering. 218 2192001-03-07 Alain Magloire 220 221 * README-alpha: Removed reference to GNU tar, add the location 222 of the CVSROOT. 223 2242001-03-06 Alain Magloire 225 226 Only the Regex patterns should be split in an array, patterns[]. 227 The dfa and KWset compiled patterns should remain global and the 228 patterns compiled all at once. 229 230 * src/search.c: include "error.h" and "xalloc.h" to get prototyping 231 of x*alloc() and error(). 232 (kwsinit): Reverse to previous behaviour and takes no argument. 233 (kwsmusts): Likewised. 234 (Gcompile): For the regex pattern, split them and each pattern 235 is put in different compiled structure patterns[]. The patterns 236 are given to dfacomp() and kwsmusts() as is. 237 (Ecompile): Likewised. 238 (Fcompile): Reverse to the old behaviour of compiling the enire 239 patterns in one shot. 240 (EGexecute): If falling to GNU regex for the matching, loop in the 241 array of compile patterns[] to find a match. 242 (error): Many error () were call with arguments in the wrong order. 243 * tests/file.sh: Simple test to check for pattern in files. 244 245 Reaction to bug report fired by Greg Louis <glouis@dynamicro.on.ca> 246 2472001-03-06 Isamu Hasegawa 248 249 In multibyte environments, handle

269 (dfafree): free new variables. 270 2712001-03-04 Alain Magloire 272 273 To get more in sync with other GNU utilities like GNU tar and fetish 274 all the supporting functions are now under lib. 275 Thanks to Jim Meyering, Volkert Bochert and Paul Eggert for 276 the code and the reminders. 277 278 * src/grep.c (fatal): Function removed, using error () from 279 lib/error.c instead. 280 (usage): Copyright updated. 281 (error): Function removed, using error () from lib/error.c instead, 282 adjust prototypes. 283 (prog): Global variable rename to program_name, to work with new 284 lib/error.c.

This doesn't take care of the cases where 480 this connection is somehow indirect. 481 482 * src/grep.c (line_buffered): new option variable. 483 (prline): if line_buffered is set fflush() is call. 484 (usage): line_buffered new option. 485 Input from Paul Eggert, doing setvbuf() may not be portable 486 and breaks grep -z. 487 4882001-02-16 Alain Magloire 489 490 Patch from Isamu Hasegawa, for multibyte support. 491 This patch prevent kwset_matcher from following problems. 492 For example, in SJIS encoding, one character has the codepoint 0x895c. 493 So the second byte of the character can match with '\' incorrectly. 494 And in eucJP encoding, there are the characters whose codepoints are 495 0xa5b9, 0xa5c8. On the other hand, there is one character whose 496 codepoint is 0xb9a5. So 0xb9a5 can match with 2nd byte of 0xa5b9 497 and 1st byte of 0xa5c8. 498 499 * configure.in: Add check for mbrtowc. 500 * src/search.c (check_multibyte_string): new function. 501 Support for multibyte string. 502 (EGexecute): call check_multibyte_string when kwset is set. 503 (Fexecute): call to check_multibyte_string. 504 (MBS_SUPPORT): new macro. 505 (MB_CUR_MAX): new macro. 506 5072001-02-16 Alain Magloire 508 509 * djgpp/config.bat: Fix for 4dos.com. 510 * m4/dosfile.m4 (HAVE_DOS_FILE_CONTENTS): Was not set. 511 Bugs noted and patched by Juan Manuel Guerrero. 512 5132001-02-16 Alain Magloire 514 515 A much requested feature, the possibility to select 516 files when doing recurse : 517 # find . -name "*.c" | xargs grep main {} 518 # grep --include=*.c main . 519 # find . -not -name "*.c" | xargs grep main {} 520 # grep --exclude=*.c main . 521 522 * src/grep.c (short_options): -R equivalent to -r. 523 (#ifdef) : Fix some inconsistencies in the use of #ifdefs, prefer 524 #if defined() wen possible. 525 (long_options): Add --color, --include and exclude. 526 (Usage): Description of new options. 527 (color): Rename color variable to color_option. 528 Removed 'always|never|auto' arguments, not necessary for grep. 529 (exclude_pattern): new variable, holder for the file pattern. 530 (include_pattern): new variable, hoder for the file pattern. 531 * src/savedir.c: Signature change, take two new argmuments. 532 * doc/grep.texi: Document, new options. 533 * doc/grep.man: Document, new options. 534 5352001-02-09 Alain Magloire 536 537 * src/grep.c (long_options): Added equivalent to -r with -R. 538 * src/grep.c (usage): added --color and --colour. 539 Noted with patch from, H.Merijn Brand and Wichert Akkerman. 540 5412001-02-09 Alain Magloire 542 543 Patch from Ulrich Drepper to provide hilighting. 544 545 * src/grep.c: New option --color. 546 (color): New static var. 547 (COLOR_OPTION): new constant. 548 (grep_color): new static var. 549 (prline): Now when color is set prline() will call the current matcher 550 to find the offset of the matching string. 551 * src/savedir.c: Take advantage of _DIRENT_HAVE_TYPE if supported. 552 * src/search.c (EGexecute, Fexecute, Pexecute): Take a new argument 553 when doing exact match for the color hiligting. 554 5552000-09-01 Brian Youmans 556 557 * doc/grep.texi: Typo fixes. 558 5592000-08-30 Paul Eggert 560 561 * doc/grep.texi (Usage): Talk about what "grep -r hello *.c" 562 means. 563 5642000-08-20 Paul Eggert 565 566 Handle range expressions correctly even when they match 567 strings with two or more characters. 568 569 * src/dfa.h (CRANGE): New enum value. Comment fix. 570 571 * src/dfa.c: Include <locale.h> if HAVE_SETLOCALE. 572 Include "hard-locale.h". 573 (prtok): Print CRANGE. 574 (hard_LC_COLLATE): New static var. 575 (lex): Return CRANGE when parsing a character range in a hard locale. 576 Don't use strcoll; it's no longer needed and wasn't correct anyway. 577 Use unsigned rather than token to hold unsigned chars. 578 (addtok): Comment fix. 579 (atom): Treat a CRANGE as if it were (.\1), approximately. 580 (dfaparse): Initialize hard_LC_COLLATE. 581 582 * src/Makefile.am (base_sources): Add hard-locale.c, hard-locale.h. 583 584 * src/hard-locale.c, src/hard-locale.h: New files, taken from 585 textutils. 586 5872000-08-20 Paul Eggert 588 589 * tests/Makefile.am (TESTS_ENVIRONMENT): Add LC_ALL=C, since 590 some of the tests assume the C locale. 591 5922000-08-16 Paul Eggert 593 594 * src/search.c (Gcompile, Ecompile): -x overrides -w, for 595 consistency with fgrep. Don't assume that sizes fit in 'int'. 596 Fix comments to match code. 597 5982000-06-06 Paul Eggert 599 600 * src/grep.c (grepdir): Don't look at st_dev when testing for 601 Mingw32 bug. 602 6032000-06-05 Paul Eggert 604 605 Port to Mingw32, based on suggestions from Christian Groessler 606 <cpg@aladdin.de>. 607 608 * src/isdir.c: New file, taken from fileutils. 609 610 * src/Makefile.am (base_sources): Add isdir.c. 611 612 * src/grep.c (grepfile): Use isdir instead of doing it inline. 613 (grepdir): Suppress ancestor check if the directory's inode and device 614 are both zero, as that occurs only on Mingw32 which doesn't support 615 inode or device. 616 617 * src/system.h (isdir): New decl. 618 (is_EISDIR): Depend on HAVE_DIR_EACCES_BUG, not D_OK. 619 Use isdir, not access. 620 6212000-06-02 Paul Eggert 622 623 Problen noted by Gerald Stoller <gerald_stoller@hotmail.com> 624 625 * src/grep.c (main): POSIX.2 says that -q overrides -l, which 626 in turn overrides the other output options. Fix grep to 627 behave that way. 628 6292000-05-27 Paul Eggert 630 631 Simplify and tune the buffer allocation strategy. Do not reserve a 632 large save area: reserve only enough bytes to hold the residue, plus 633 page alignment. Put a newline sentinel before the buffer, for speed 634 when searching backwards for newline. 635 636 * src/grep.c (ubuffer, bufsalloc, PREFERRED_SAVE_FACTOR, page_alloc): 637 Remove. All uses changed. 638 (INITIAL_BUFSIZE): New macro. 639 (reset, fillbuf): Use simpler buffer allocation strategy. 640 (reset): Check for preposterously large pagesize that would cause 641 later calculations to overflow. 642 (fillbuf): Do not resize buffer if there's room at the end for 643 at least one more page. This greatly increases performance when 644 reading from non-regular files that contain no newlines. 645 When growing the buffer, double its size instead of using a 646 more complicated algorithm. 647 (prtext, grep): Speed up by relying on the newline sentinel before the 648 start of the buffer. 649 (grep): When looking backwards for the last newline in a buffer, 650 stop when we hit the residue, since it can't contain a newline. 651 This avoids an O(N**2) algorithm when reading binary data from 652 a pipe. Use a sentinel to speed up the backward search for newline. 653 (nlscan): Undo previous change; it wasn't needed and just complicates 654 and slows down the code a tad. 655 6562000-05-24 Paul Eggert 657 658 Handle very large input counts better. Bug noted by Jim Meyering. 659 660 * src/grep.c (totalcc, totalnl): Use uintmax_t, not off_t. 661 (add_count): New function. 662 (nlscan, prline, grep): Use it to check line and byte count overflows. 663 (nlscan, grep): Don't keep track of counts when not asked to; this 664 avoids unnecessary overflow diagnostics. 665 (print_offset_sep): Now takes args of type uintmax_t and char, 666 not off_t and int. 667 6682000-05-16 Paul Eggert 669 670 Problem reported by Bob Proulx <rwp@hprwp.fc.hp.com>, this patch 671 is base on his finding, with appropiate corrections. 672 673 * src/grep.c (main): Fix bug: -x and -w matched even when no 674 patterns were specified. 675 * tests/empty.sh: Test for -x and -w bug in grep 2.4.2. 676 6772000-04-24 Paul Eggert 678 679 POSIX.2 conformance fixes: grep -q now exits with status zero 680 if an input line is selected, even if an error also occurs. 681 grep -s no longer affects exit status. 682 683 * src/grep.c (suppress_errors): Move definition earlier so 684 that suppressible_error can use it. 685 (suppressible_error): New function. 686 (exit_on_match): New var. 687 (grepbuf): If exit_on_match is nonzero, exit with status zero 688 immediately. 689 (grep, grepfile, grepdir): Invoke suppressible_error. 690 (main): -q sets exit_on_match. 691 692 * doc/grep.1, doc/grep.texi, NEWS: 693 Document -q's behavior as required by POSIX.2. 694 695 * tests/status.sh: 696 Test for -q and -s behavior as conforming to POSIX.2. 697 6982000-04-20 Paul Eggert 699 700 * tests/Makefile.am (TESTS_ENVIRONMENT): 701 Set GREP_OPTIONS to the empty string. 702 7032000-04-20 Paul Eggert 704 705 * tests/status.sh: Fix typo: test -b -> test -r. 706 7072000-04-20 Paul Eggert 708 709 * src/dfa.c (lex): 710 Do not assume that [c] is equivalent to [c-c]; this isn't true 711 if LC_COLLATE specifies that some characters are equivalent. 712 (setbit_case_fold): New function. 713 (lex): Use it to simplify the code a bit. 714 7152000-04-17 Paul Eggert 716 717 Do CRLF munging only if HAVE_DOS_FILE_CONTENTS, instead of 718 having it depend on O_BINARY (which leads to incorrect results 719 on BeOS, VMS, and MacOS). 720 721 * bootstrap/Makefile.try (DEFS): Add -DHAVE_DOS_FILE_CONTENTS. 722 * src/system.h (SET_BINARY): Define only if HAVE_DOS_FILE_CONTENTS. 723 (O_BINARY): Do not define. 724 725 * m4/dosfile.m4: Define HAVE_DOS_FILE_CONTENTS if it appears we're 726 using DOS. 727 728 * src/grep.c (undossify_input, fillbuf, dosbuf.c, prline, main): 729 Depend on HAVE_DOS_FILE_CONTENTS, not O_BINARY, when handling CRLF 730 matters. 731 (grepfile, main): Depend on SET_BINARY, not O_BINARY, when 732 handling binary files on hosts that care about text versus binary. 733 7342000-04-17 Paul Eggert 735 736 * lib/getpagesize.h (getpagesize): Define to B_PAGE_SIZE if 737 __BEOS__ is defined. Based on a fix by Bruno Haible 738 <haible@clisp.cons.org>. 739 7402000-04-17 Bruno Haible 741 742 * src/system.h [BeOS]: Ignore O_BINARY. 743 * src/getpagesize.h [BeOS]: Define getpagesize() as B_PAGE_SIZE. 744 7452000-04-10 Paul Eggert 746 747 * doc/grep.1, doc/grep.texi, NEWS: -C now requires an operand. 748 * src/grep.c (short_options, long_options, main, usage): Likewise. 749 (context_length_arg): Renamed from ck_atoi. Now reports an error 750 and exits if the number is out of range for a context length. 751 (get_nondigit_option): New function, which checks for overflow 752 correctly, and which does not parse nonadjacent strings of digits 753 into a single number. 754 (main): Use get_nondigit_option instead of doing the code inline. 755 With -A, -B, and -C, optarg is now guaranteed to be nonzero. 756 7572000-04-08 Paul Eggert 758 759 Now that we know that the input is always terminated by a 760 newline before the matching algorithms see it, clean up the 761 matching algorithms so that they no longer need to modify the 762 input by inserting a sentinel newline, and no longer worry 763 about running off the end of the buffer due to a missing sentinel. 764 765 * src/grep.c (nlscan, prpending, prtext, grepbuf): Do not 766 worry about running off the end of the input buffer, since 767 it's now guaranteed to end in the sentinel newline. 768 * src/search.c (EGexecute, Pexecute): Likewise. 769 770 * src/dfa.c (prtok, dfasyntax, dfaparse, copy, merge, state_index, 771 epsclosure, dfaexec, dfacomp): 772 Change many instances of "T *" to "T const *", to catch 773 any inadvertent programming errors made during this conversion. 774 * src/dfa.h (dfacomp, dfaexec, dfaparse): Likewise. 775 * src/grep.c (struct stats.parent, long_options, grepdir, 776 compile, execute, fillbuf, lastnl, lastout, nlscan, prline, 777 prpending, prtext, grepbuf, grep, grepfile, grepdir): Likewise. 778 * src/grep.h (struct matcher.compile, struct matcher.execute): 779 Likewise. 780 * src/kwset.c (struct kwset.trans, kwsalloc, kwsincr, treefails, 781 treedelta, hasevery, treenext, bmexec, cwexec, kwsexec): Likewise. 782 * src/kwset.h (kwsalloc, kwsincr, kwsexec): Likewise. 783 * src/search.c (kwsmusts, Gcompile, Ecompile, EGexecute, Pcompile, 784 Pexecute): Likewise. 785 786 * src/dfa.c (dfaexec): 787 Use size_t, not char *, to avoid worrisome casts to convert 788 char const * to char *. 789 * src/dfa.h (dfaexec): Likewise. 790 * src/grep.c (execute): Likewise. 791 * src/grep.h (execute): Likewise. 792 * src/kwset.c (bmexec, cwexec, kwsexec): Likewise. 793 * src/kwset.h (struct kwsmatch.offset, kwsalloc, kwsincr, 794 kwsexec): Likewise. 795 * src/search.c (EGexecute, Fexecute, Pexecute): Likewise. 796 797 * src/dfa.h (_PTR_T): Depend on defined __STDC__, not __STDC__. 798 (PARAMS): Depend on PROTOTYPES, not __STDC__. 799 800 * src/dfa.c (dfasyntax): Last arg is unsigned char, not int. 801 * src/dfa.h (dfasyntax): Likewise. 802 803 * src/dfa.h (struct dfa): Remove member newlines; no longer needed. 804 * src/dfa.c (build_state, dfaexec, dfafree): Do not worry 805 about special newline state. 806 807 * src/search.c (matchers): Move definition to end of file, so 808 that we don't need forward decls. 809 (lastexact): Remove. 810 (kwset_exact_matches): New var; subsumes old lastexact var. 811 All uses changed. 812 813 * src/dfa.c (index): Remove macro. 814 (REALLOC_IF_NECESSARY): Skip unnecessary test. 815 (tstbit, setbit, clrbit): Declare arg to be unsigned, to help compiler. 816 (copyset, zeroset, equal): Use C builtin primitives, to help compiler. 817 (dfaexec): Do not modify input string. 818 Remove newline parameter; no longer needed. 819 (comsubs): Use strchr, not index. 820 821 * src/grep.h (matchers): Use fixed name size, not pointer (as 822 there's no need for the extra flexibility). All uses changed. 823 824 * src/kwset.h (struct kwsmatch.offset): Renamed from beg, with 825 change of type to size_t. All uses changed. 826 827 * src/grep.c (reset): No longer need kludge for dfaexec. Simplify. 828 (reset, grepbuf): Adjust to new interface for 'execute'. 829 (install_matcher): List is now terminated by null compile, 830 not null name. 831 Do not invoke setrlimit if that wouldn't change the limit. 832 833 * src/dfa.c (xcalloc, xmalloc, xrealloc, prtok, tstbit, setbit, 834 clrbit, copyset, zeroset, notset, equal, charclass_index, 835 looking_at, lex, addtok, atom, nsubtoks, copytoks, closure, 836 branch, regexp, copy, insert, merge, delete, state_index, 837 build_state, build_state_zero, icatalloc, icpyalloc, istrstr, 838 ifree, freelist, enlist, comsubs, addlists, inboth): 839 Remove forward decls; no longer needed. 840 * src/grep.c (ck_atoi, usage, error, setmatcher, 841 install_matcher, prepend_args, prepend_default_options, 842 page_alloc, reset, fillbuf, grepbuf, prtext, prpending, prline, 843 print_offset_sep, nlscan, grep, grepfile): Likewise. 844 * src/kwset.c (enqueue, treefails, treedelta, hasevery, 845 treenext, bmexec, cwexec): Likewise. 846 * src/search.c (Gcompile, Ecompile, EGexecute, Fcompile, Fexecute, 847 Pcompile, Pexecute, kwsinit): Likewise. 848 849 * src/search.c (Pcompile): Do not assume newly allocated 850 storage is zeroed. 851 8522000-04-06 Paul Eggert 853 854 * doc/grep.1, doc/grep.texi, NEWS: Improve the explanation of 855 locale-dependent behavior of range expressions. Mention 856 LC_COLLATE, since this affects range expressions. 857 8582000-03-26 Paul Eggert 859 860 * Makefile.am (ACINCLUDE_INPUTS): Add decl.m4, inttypes_h.m4, 861 uintmax_t.m4, ulonglong.m4, xstrtoumax.m4. 862 * m4/Makefile.am (EXTRA_DIST): Likewise. 863 864 * src/Makefile.am (base_sources): 865 Add xstrtol.c, xstrtol.h, xstrtoumax.c. 866 (EXTRA_DIST): Add strtol.c. 867 868 * configure.in (jm_AC_TYPE_UINTMAX_T, jm_AC_PREREQ_XSTRTOUMAX, 869 HAVE_DECL_STRTOUL, HAVE_DECL_STRTOULL): Add. 870 (AC_REPLACE_FUNCS): Add strtoul. 871 872 * src/grep.c: Include xstrtol.h. 873 (ck_atio): Use xstrtoumax and do proper overflow checking. 874 (max_count, outleft): Now off_t, not int. 875 (main): Likewise. Use xstrtoumax to convert max_count from string. 876 877 * acconfig.h (HAVE_DECL_STRTOUL, HAVE_DECL_STRTOULL): New #undefs. 878 (HAVE_STPCPY, ENABLE_NLS, HAVE_CATGETS, HAVE_GETTEXT, 879 HAVE_LC_MESSAGES): Remove. 880 881 * m4/decl.m4, m4/inttypes_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4, 882 m4/xstrtoumax.m4, src/strtol.c, src/strtoul.c, src/strtoull.c, 883 src/strtoumax.c, src/xstrtol.c, src/xstrtol.h, src/xstrtoumax.c: 884 New files, taken unchanged from textutils, fileutils, sh-utils 885 and/or tar. 886 8872000-03-23 Paul Eggert 888 889 * src/search.c (Pcompile): Add support for NUL bytes in 890 Perl regular expressions. 891 8922000-03-23 Paul Eggert 893 894 * NEWS, doc/grep.1, doc/grep.texi: Change --pcre to --perl-regexp. 895 * src/grep.c (long_options, usage): Likewise. 896 897 * doc/grep.1, doc/grep.texi: Remove pgrep program. 898 * src/Makefile.am (bin_PROGRAMS): Likewise. 899 (pgrep_SOURCES): Remove. 900 901 * src/grep.c (main): Rename matcher from "pgrep" to "perl". 902 * src/search.c (matchers): Likewise. 903 904 * src/search.c: Do not include stdio.h; no longer needed. 905 (NILP): Remove. 906 (sub): No longer static. 907 (n_pcre): Remove. 908 (cre): No longer an array. Present only if HAVE_LIBPCRE. 909 (extra): New variable. 910 (Pcompile): Use fatal to report errors. 911 This also removes a possible core dump. 912 Add checks (marked FIXME) for restrictions in pcre. 913 Use pcre_maketables for proper localized behavior. 914 (Pcompile, Pexecute): Use GNU coding style. 915 The argument is a single pattern, not a list of patterns separated 916 by newlines; this is for consistency with grep and egrep. 917 Use pcre_study for speed. 918 (Pexecute): Abort if we lack pcre. 919 Abort if pcre_exec reports an impossible error. 920 Use code similar to the rest of search.c 921 to narrow down to the line we've found. 922 9232000-03-21 Alain Magloire 924 925 * configure.in: added AC_CHECK_LIB(pcre, pcre_exec) 926 * ChangeLog: Typos corrected. 927 * src/search.c: new MACRO HAVE_LIBPCRE 928 9292000-03-21 H.Merijn Brand 930 931 * src/Makefile.am(bin_PROGRAMS): added pgrep and new macro 932 pgrep_SOURCES. 933 * src/search.c: new functions Pcompile() and Pexecute() 934 to support PCRE. Update matcher[] array for pgrep. 935 * src/grep.c: new short and long option --pcre and -P. 936 usage() updated. 937 9382000-03-21 Bastiaan Stougie 939 940 Improvement of the -m or --max-count option. Now works for NUM > 1 and 941 prints trailing context for the last matching line. 942 943 * src/grep.c 944 (after_last_match): Is a new off_t variable that replaces inputhwm 945 to retain the correct input offset even after a call to fillbuf. Note 946 that after_last_match has a different meaning than inputhwm: 947 it always points to the offset in the input of the first byte after 948 the last matching line, and is 0 if no matching line has been found 949 yet. 950 (grep): Print trailing context after the NUMth match when the -m NUM 951 option is used. 952 (grep): Added comment. Should have been commented already. 953 (grepbuf): Now updates outleft correctly. This fixes the bug that the 954 -m NUM option did not stop after NUM lines for NUM greater than 1. 955 (grepbuf, prtext): Now update after_last_match instead of inputhwm. 956 (fillbuf): No longer updates inputhwm. 957 (prpending): When outputting trailing context of the max_count-th 958 matching line, stop at the first matching line. 959 (grepfile): Seek to after_last_match or eof, depending on the values 960 of outleft and bufmapped. 961 (usage): added the -m or --max-count option to the help message. 962 * doc/grep.texi, doc/grep.1: Document the change of the -m option. 963 9642000-03-17 Paul Eggert 965 966 Add new -m or --max-count option, based on a suggestion by 967 Bastiaan Stougie. 968 969 * doc/grep.texi, doc/grep.1: Document it. 970 * src/grep.c (short_options, long_options, main): Add it. 971 (inputhwm): New variable. 972 (fillbuf, prtext, grepbuf): Set it. 973 (bufmapped): Now a macro (defined to zero) if HAVE_MMAP is not defined. 974 (max_count, outleft): New variables. 975 (prtext, grepbuf, grep): Don't output more than outleft lines. 976 (grepfile): If grepping standard input, seek to the limit of what 977 we've read before exiting. This fixes a bug with mmapped input, 978 and is needed for proper -m support. 979 (main): Exit immediately if -m 0 is specified. 980 |
