+
+2005-11-18 Charles Levert <charles_levert@gna.org>
+
+ * tests/foad1.sh: Use ": ${VERBOSE=}" so that the caller can
+ set it without modifying the script; the usual caller (Makefile)
+ still leaves it untouched (usually unset, so it's off by default).
+ Modify "-m1 -A99 '^...$'" tests that failed so that their
+ expectation now corresponds to the output currently produced
+ by grep. Those tests used to expect that two selected (or
+ selectable) lines be output, even with -m1. Nothing was
+ modified with other similar tests that output _context_ lines
+ after one selected line has been output with -m1; they used to
+ and still succeed. Although tests/yesno.sh now provides a more
+ comprehensive framework for testing -m/-C feature interaction,
+ it doesn't exercise mixing them with anchors so the whole
+ relevant tests/foad1.sh test group is kept, notably to check
+ that grep doesn't crash when it is run.
+
+2005-11-17 Charles Levert <charles_levert@gna.org>
+
+ On 2005-06-21, many changes were made that affected --color,
+ --only-matching, and --invert-match. Some of them introduced a
+ misunderstanding between the concepts of matched/non-matched and
+ selected/rejected lines. Furthermore, a few bugs with -v sneaked
+ in stemming from this. This set of changes aims to rectify most
+ of this situation. Some GREP_COLORS capabilities are also added
+ as a result of the clarification. (Further issues with -v/-o/-C
+ feature interaction still remain to be sorted out.)
+
+ * src/grep.c: Rename/add global variables, macros, and capabilities:
+ SEP_CHAR_MATCH --> SEP_CHAR_SELECTED
+ SEP_CHAR_CONTEXT --> SEP_CHAR_REJECTED
+ SEP_STR_CHUNK --> SEP_STR_GROUP
+ grep_color --> selected_match_color + context_match_color
+ mlines_color --> selected_line_color
+ context_color --> context_line_color
+ "ml" --> "sl"
+ "mt" --> "mt" = "ms" + "mc"
+ --> "rv" (reverse "sl"/"cx" when -v)
+ * src/grep.c (color_cap_mt_fct, color_cap_rv_fct): New functions.
+ * src/grep.c (print_line_tail): Renamed color argument to line_color.
+ * src/grep.c (print_line_middle, prline): Revert part of the logic to
+ a pre-2005-06-21 one so that lines with matches have their matched
+ parts properly handled again ("m?" colors or --only-matching),
+ whether or not -v is specified. Whole line colors ("sl", "cx")
+ follow a selected / rejected(context) logic, as opposed to a
+ matched / non-matched one (unless "rv"). Matched text colors ("ms",
+ "mc") always follow a selected / rejected(context) logic,
+ regardless of "rv", because only matched lines use them anyway.
+ pr_line_middle() now takes additional line_color and match_color
+ arguments computed by prline() prior to calling that function.
+ The old logic was a buggy hybrid matched / rejected(context) one.
+ * src/grep.c (prpending, prtext, grepfile): Renamed macro invocations.
+ * src/grep.c (parse_grep_colors): Update top comment.
+ * src/grep.c (main): GREP_COLOR (singular) now sets both
+ selected_match_color and context_match_color.
+
+2005-11-16 Charles Levert <charles_levert@gna.org>
+
+ * src/search.c (Pcompile): Clarify message for the -P option
+ not being supported so that users don't assume it's a run-time
+ problem, but know that it's a compile-time configuration choice.
+ Based on an idea by: Benno Schulenberg <benno@nietvergeten.nl>.
+
+2005-11-13 Charles Levert <charles_levert@gna.org>
+
+ * tests/yesno.sh: New file. Test feature interaction
+ of -C, -v, -o, and -m. This reveals bugs, including some I
+ introduced on 2005-06-21, but also others.
+ * tests/Makefile.am (TESTS): Add yesno.sh.
+ * tests/Makefile.am (CLEANFILES): Add cspatfile and csinput, as
+ created by fmbtest.sh. Add yesno.txt, as created by yesno.sh.
+
+2005-11-11 Charles Levert <charles_levert@gna.org>
+
+ * configure.in (ALL_LINGUAS): Add languages that were missing
+ from this variable (bg, ca, da, nb, tr), but that GNU grep supports
+ with a po/xx.po file. Reported by Tony Abou-Assaleh <taa@acm.org>.
+
+ * src/search.c (Pcompile): Abort in error if -P and multiple patterns
+ are specified, with an error message explaining the situation.
+ Fixing this won't be simple; the '\n' characters separating the
+ patterns cannot just be replaced by '|' to create an alternation as
+ back-references are assumed to be local to each individual pattern.
+
+ * src/grep.c (parse_grep_colors, main): Replace all uses of
+ fprintf(stderr, _("%s: foo\n"), program_name, ...) with
+ error(0, 0, _("foo"), ...) for uniformization and simplification
+ of warning messages that will be up for localization. (My bad.)
+
+2005-11-10 Charles Levert <charles_levert@gna.org>
+
+ The introduction of the --only-matching and --color GNU extensions
+ to grep added the requirement that each execute() implementation
+ not only be able to identify matching lines as a whole, but also
+ individual "exact" matches within a line known to be matching,
+ from leftmost to rightmost match, when the output from matching
+ lines is actually produced. The interface and implementations
+ of execute() were not up to it. This set of changes aims to
+ rectify that situation. Previously failing tests relative to
+ left anchors (^ and \<) and -w should now pass. This fixes
+ <https://savannah.gnu.org/bugs/?func=detailitem&item_id=11579>,
+ <https://savannah.gnu.org/patch/?func=detailitem&item_id=1834>,
+ <https://savannah.gnu.org/bugs/?func=detailitem&item_id=8243>,
+ and possibly part of other, bigger, pending patches. The problem
+ was also compounded by the POSIX requirement to support a pattern
+ list instead of just an individual pattern (for -G and -E as well).
+
+ * tests/foad1.sh: Test for increasing/decreasing-length word
+ matches, given pattern order, and leftmost/longest match.
+ * tests/fmbtest.sh: Modify test #6 according to new expectations.
+ Better document what tests #6 and #7 are actually for. Eliminate
+ test #5 in favor of bringing tests #6 and #7 within the F G E loop.
+ * src/grep.h (EXECUTE_ARGS): Change last argument from "int exact"
+ to "char const *start_ptr". Testing for "start_ptr" being non-NULL
+ retains the same semantics as testing for "exact" being non-zero.
+ * src/grep.c (print_line_middle): Call execute() with whole
+ buffer to work on, but using current position as start_ptr.
+ * src/grep.c (prpending, grepbuf): Call execute() with NULL
+ as start_ptr.
+ * src/search.c (EGexecute, Fexecute, Pexecute): When start_ptr is
+ non-NULL, return first match from it as an offset relative to buf.
+ * src/search.c (EGexecute): Consider all patterns if many and,
+ for an exact match, return the best one (leftmost, then longest).
+ Don't explore worst solutions, of course (branch and bound).

+ * src/grep.c (main): Fix a subtle memory allocation bug introduced
+ with the mb_icase_keys() function, which can call xrealloc() or
+ free() on keys, by making sure keys is always dynamically allocated.
+
+2005-11-09 Charles Levert <charles_levert@gna.org>
+
+ * doc/grep.1, doc/grep.texi: Advise users to test for

+ detect errors, for portability with other POSIX-compliant
+ implementations.
+
+2005-11-09 Charles Levert <charles_levert@gna.org>
+
+ The following set of changes aims to make "egrep" and "fgrep"
+ minimal executable programs for legacy applications, instead of
+ shell scripts. This "fgrep" is much smaller than "grep".
+ This set of changes appears more daunting than it really is.
+
+ * src/egrep.c, src/fgrep.c, src/esearch.c, src/fsearch.c: New files
+ that #define either EGREP_PROGRAM or FGREP_PROGRAM and #include
+ the corresponding generic (i.e., non e or f specific) *.c file.
+ * src/grepmat.c: Remove whole file.
+ * src/Makefile.am: Remove no-dependencies from AUTOMAKE_OPTIONS.
+ Add definitions to make "egrep" and "fgrep" specific standalone
+ executable programs that only use the source files they need.
+ Remove rules for "egrep" and "fgrep" shell scripts.
+ * src/grep.h: #define GREP_PROGRAM if both EGREP_PROGRAM and
+ FGREP_PROGRAM are #undef. Only declare matchers[] in this case
+ along with the compile_fp_t and execute_fp_t function pointers
+ typedefs, otherwise declare prototypes for straight compile()
+ and execute() functions for the specialized "egrep" and "fgrep"
+ programs. Remove the extern declaration for matcher.
+ Define COMPILE_RET, COMPILE_ARGS, EXECUTE_RET, EXECUTE_ARGS,
+ COMPILE_FCT, and EXECUTE_FCT helper preprocessor macros.
+ * src/grep.c (short_options, long_options, usage, main): Only
+ support -G, -E, -F, -P, and -X for GREP_PROGRAM, but not for
+ EGREP_PROGRAM or FGREP_PROGRAM. Customize usage messages.
+ * src/grep.c (set_limits): New function with unchanged code,
+ called from main(), because it shouldn't be in install_matcher()
+ since it was already matcher-independent.
+ * src/grep.c (matcher): Add as static, only for GREP_PROGRAM.
+ * src/grep.c (setmatcher, install_matcher): Only for GREP_PROGRAM.
+ * src/grep.c (main): Remove any tweaking and dependence on argv[0].
+ * src/grep.c (print_line_middle, prpending, grepbuf, main): Call
+ compile() and execute() directly, not through a function
+ pointer dereferencing notation, so that it works with both
+ straight functions (in EGREP_PROGRAM and FGREP_PROGRAM) and
+ function pointers (in GREP_PROGRAM).
+ * src/search.c (<regex.h>, "dfa.h", dfa, pattern0, patterns,
+ pcount, dfaerror, kwset_exact_matches, kwsmusts): Only
+ include/declare/define if not FGREP_PROGRAM.
+ * src/search.c: Remove function prototypes for all functions
+ that are not used before their definition, since this is just
+ a hassle now with their varying names and conditional definition.
+ * src/search.c (GEAcompile): Rename from Ecompile(). Add new
+ syntax_bits argument/variable. Use as compile() for EGREP_PROGRAM.
+ Put in the needed RE_ICASE fix, albeit commented-out for now.
+ Make sure to free() modified word/line pattern after use, if any.
+ * src/search.c (Gcompile): Merge with GEAcompile() then remove.
+ * src/search.c (Gcompile, Acompile, Ecompile): New small functions
+ that call GEAcompile(), now that matcher is not an extern variable.
+ * src/search.c (GEAcompile, Gcompile, Acompile, Ecompile,
+ Fcompile, Pcompile, EGexecute, Fexecute, Pexecute, matchers):
+ Only define when needed according to *GREP_PROGRAM, and rename
+ to just compile() and execute() when appropriate.
+ * grep/bootstrap/Makefile.try: Similar changes.
+
+2005-11-08 Charles Levert <charles_levert@gna.org>
+
+ * README.DOS, TODO, grep.spec, doc/grep.1, doc/grep.texi,
+ src/grep.h, po/da.po, po/nb.po, po/no.po, po/sv.po:
+ Replace all capitalized "Grep" by a lowercase "grep", except
+ in citations. Reported by Benno Schulenberg <benno@nietvergeten.nl>
+ from the <https://bugs.debian.org/190551>
+ entry in the Debian bug tracker.
+ * doc/grep.1, doc/grep.texi: Explain that the "egrep" and "fgrep"
+ commands are deprecated and provided for historical applications.
+ Replace some "egrep" uses by "grep -E" to promote the newer usage.
+ Typeset "zgrep" as a command. Fix some spacing and punctuation bugs.
+
+2005-11-08 Julian Foad <julianfoad@btopenworld.com>
+
+ * doc/grep.texi: Rewrite a poorly written usage example about
+ back-references, and tweak another. New text by Benno Schulenberg.
+
+2005-11-04 Charles Levert <charles_levert@gna.org>
+
+ * src/grep.c (mb_icase_keys): New function to properly lowercase
+ keys if match_icase. The problem was that some multi-octet
+ characters can get longer or shorter upon this conversion, so that
+ it cannot just naively be done in place on the same memory buffer.
+ * src/grep.c (main): Call mb_icase_keys (and remove in-line code).
+
+ * tests/foad1.sh: Duplicate three "-o -b" tests for the "-F"
+ mode because it relies on a different code path that deserves
+ the same kind of testing.
+
+2005-09-27 Stepan Kasal <kasal@ucw.cz>
+
+ * doc/grep.1: Fix a typo.
+
+2005-08-24 Charles Levert <charles_levert@gna.org>
+
+ * src/grep.c (print_line_middle): In case of an empty match,
+ make minimal progress and continue instead of aborting process
+ of the remainder of the line, in case there's still an upcoming
+ non-empty match.
+ * tests/foad1.sh: Add two tests for this.
+ * doc/grep.texi, doc/grep.1: Document this behavior, since
+ --only-matching and --color are GNU extensions which are
+ otherwise unspecified by POSIX or other standards.
+
+2005-07-26 Charles Levert <charles_levert@gna.org>
+
+ * tests/pcre.sh: New file. Add test 1.
+ * tests/Makefile.am: Add pcre.sh to TESTS.
+
+2005-07-07 Charles Levert <charles_levert@gna.org>
+
+ * src/grep.c: Remove all xm capability code.
+
+2005-07-05 Charles Levert <charles_levert@gna.org>
+
+ * doc/grep.texi: Add missing green color in GREP_COLORS description.
+ * doc/grep.1: Fix typo and reorganize GREP_COLORS documentation.
+
+ * src/kwset.c (DEPTH_SIZE): New macro to anticipate
+ architectures/compilers where CHAR_BIT is not 8 (we assume it
+ won't be less than 4, which would be non-standard and unlikely).
+ Checked to hold for CHAR_BIT up to 1023 (and maybe more)!
+ * src/kwset.c (kwsincr): Use DEPTH_SIZE in two array declarations.
+
+ * src/kwset.c (kwsincr): When a second obstack_alloc() call fails,
+ free what the first one successfully allocated by popping it
+ off the top of the obstack, before returning in error, just
+ to keep things clean.
+ * src/kwset.c (kwsprep): Verify return value of obstack_alloc()
+ and return a memory exhausted error if so. This function had
+ a prototype to return such errors, but never did.
+
+2005-07-04 Charles Levert <charles_levert@gna.org>
+
+ * src/kwset.c: Readability changes.
+ Replace uses of 0 for pointer values by NULL.
+ Generalize use of existing U() macro to whole file.
+
+ * src/kwset.c (kwsprep): Use memset() and memcpy() when appropriate.
+
+ * src/kwset.c (kwsprep): Move three variable declarations to
+ the single {}-block where they are used.
+
+ * src/kwset.c (kwsprep): Optimize search for mind2 value by
+ starting from the end of the target[] array.
+
+2005-06-22 Charles Levert <charles_levert@gna.org>
+
+ * grep/autogen.sh, grep/src/Makefile.am, grep/tests/backref.sh,
+ grep/tests/bre.sh, grep/tests/empty.sh, grep/tests/ere.sh,
+ grep/tests/file.sh, grep/tests/fmbtest.sh, grep/tests/foad1.sh,
+ grep/tests/khadafy.sh, grep/tests/options.sh,
+ grep/tests/spencer1.sh, grep/tests/spencer2.sh,
+ grep/tests/status.sh, grep/tests/warning.sh: As per autoconf's
+ "Portable Shell Programming" guidelines, replace all instances
+ of "#!/bin/sh" by "#! /bin/sh" (notice the space).
+
+2005-06-21 Charles Levert <charles_levert@gna.org>
+
+ * src/grep.c (nlscan): Make this function more robust by removing
+ the undocumented assumption that its "lim" argument points
+ right after a line boundary. This will be used later to fix
+ --byte-offset's broken behavior. Patch #3769.
+
+ * src/grep.c (main): Add a test to check if -o/--only-matching
+ and context lines are both specified and if so, set both context
+ specifications (before and after) to zero then print an explicit
+ warning to stderr explaining what was done and why (as opposed
+ to drastically aborting the process in error). Patch #3768.
+ Other code needs this zero setting to work correctly without
+ having to repeatedly test for this conflictual condition.
+
+ * tests/foad1.sh: Add tests combining -o, -n/-b/-H, and -i,
+ since there are separate code paths for -i. Add tests combining
+ -o, -n/-b/-H, and -3, since any context line specification
+ should be ignored when combined with -o.
+ * src/grep.c (print_line_head): New function, culled off the
+ top content of prline(). Adds a guard against "lastnl" having
+ already reached "lim", which can happen when if the function
+ is called more than once per line.
+ * src/grep.c (prline): Now calls print_line_head(), not only at
+ the beginning to replace the moved code when -o is not
+ specified, but also for each match when -o is specified (two
+ code paths with this). Patch #3770, more or less. This makes
+ all tests combining -o and -n/-b/-H pass, which they didn't
+ before. Fixes bug #12727.
+
+ * src/grep.c (SEP_CHAR_MATCH, SEP_CHAR_CONTEXT, SEP_STR_CHUNK):
+ New macros for ':', '-', and "--". Used throughout the file.
+ Will be used even more in upcoming updates, so good to have now.
+
+ * src/grep.c: The new GREP_COLORS (plural) framework, only
+ partially used at this point to make for a simpler initial
+ patch in CVS. A subset of patch #3644 on Savannah.
+ * src/grep.c (color_cap_ne_fct, color_cap_xm_fct, print_filename,
+ print_sep, parse_grep_colors): New functions.
+ * src/grep.c (prtext, grepfile, main): Existing functions modified
+ to use the new framework.
+ * doc/grep.texi, doc/grep.1: Document GREP_COLORS.
+
+ * src/grep.c: The new -T/--initial-tab framework, only
+ partially used at this point to make for a simpler initial
+ patch in CVS. A subset of patch #3644 on Savannah.
+ The option name/calling convention is the same as for GNU diff.
+ * doc/grep.texi, doc/grep.1: Document -T/--initial-tab.
+
+ * src/grep.c (print_offset): Renamed print_offset_sep() to better
+ represent its new functionality; new calling convention.
+ * src/grep.c (print_offset, print_line_head): Use and implement
+ missing parts of the GREP_COLORS and -T/--initial-tab frameworks.
+
+ * src/grep.c (print_line_middle, print_line_tail): New functions,
+ unused for now, intended to allow a simplifying rewrite of
+ prline(). Adding them first will make for cleaner CVS patches.
+
+ * src/grep.c (prline): Simplifying rewrite using
+ print_line_middle() and print_line_tail(). No longer attempts
+ to find matches to colorize in context lines, thus avoiding
+ costly calls to (*execute)(), since we know by then that they
+ can't contain any by definition. There are no longer four
+ different code paths whether -o and -i are each specified
+ or not; they have been unified into one, which should help
+ avoid bugs similar to previous ones due to not updating all
+ code paths in a synchronized fashion. The -i code has been
+ explicitly marked since it doesn't belong there and should
+ be removed as soon as other -i code elsewhere is fixed.
+ The remaining GREP_COLORS functionality is implemented.
+ Savannah patch #3771 and patch #3644, heavily reworked.
+
+ * src/grep.c (color_cap_ne_fct, color_cap_xm_fct,
+ print_line_middle, print_line_tail): Make these four functions
+ static.
+
+2005-06-20 Charles Levert <charles_levert@gna.org>
+
+ * src/grep.c: Extensively document the SGR/EL-to-Right issue.
+
+ * src/grep.c: Explain the context and logic for choosing default
+ --color screen attributes (SGR parameters).
+
+2005-06-15 Charles Levert <charles_levert@gna.org>
+
+ * tests/foad1.sh: Since this script is run by /bin/sh, it
+ must work under posix mode. That means not using assignment
+ statements right before a function call (LC_ALL=... grep_test,
+ in this case), because it won't do the expected thing.
+
+2005-06-14 Charles Levert <charles_levert@gna.org>
+
+ Fix bug #11022 (Line wrapping causes GREP_COLOR background
+ color to "smear") by outputting a "clear to end of line"
+ control sequence after each SGR (Select Graphic Rendition)
+ control sequence (START and END). This also avoid similar
+ problems with HT (tab) characters.
+
+ * src/grep.c (SGR_START, SGR_END, PR_SGR_FMT, PR_SGR_FMT_IF,
+ PR_SGR_START, PR_SGR_END, PR_SGR_START_IF, PR_SGR_END_IF):
+ New macros.
+ * src/grep.c (prline): Use the new macros.
+ * tests/fmbtest.sh, tests/foad1.sh: Adjust the regression tests
+ to expect the new control sequences.
+
+2005-05-06 Charles Levert <charles_levert@gna.org>

+ file "gettext/gettext-runtime/ABOUT-NLS".
+
+2005-04-29 Julian Foad <julianfoad@btopenworld.com>
+

+ PATCHES.AM. Thanks to Tony Abou-Assaleh for this. Patch #3961.
+
+2005-04-29 Charles Levert <charles_levert@gna.org>
+
+ * src/grep.c: Fix typo in prline()'s --only-matching --ignore-case
+ code path; this fixes bug #9768 and passes one more test
+ in tests/foad1.sh. This whole code path should be removed in
+ the future, when other --ignore-case issues are dealt with.
+
+2005-04-28 Julian Foad <julianfoad@btopenworld.com>
+
+ * tests/foad1.sh: Remove Bash-specific syntax.

+
+2005-04-27 Julian Foad <julianfoad@btopenworld.com>
+
+ Fix a bug reported by Elliott Hughes in patch #1834 whereby "grep -Fw"

+ Gordon Lack; tests based on reproduction recipes by Gordon Lack.
+
+ * src/search.c (Fexecute): Fix the "match_words" case.
+ * tests/foad1.sh: Modify the test framework so that the "PATTERN"

+
+ * tests/foad1.sh: Add tests for "--color", most initially failing.
+ * tests/fmbtest.sh: New file of tests for "grep -i" with multi-byte

+
+2005-04-11 Julian Foad <julianfoad@btopenworld.com>
+
+ * doc/grep.texi, doc/grep.1: Document USG grep -s too.

+
+2005-03-09 Stepan Kasal <kasal@ucw.cz>

+
+2004-11-12 Stepan Kasal <kasal@ucw.cz>
+

+ David Clissold, wrote:
+ a small bug in the GNU grep 2.4.2, which may have gone unnoticed
+ because it only causes a failure if building on a system with large
+ files enabled (e.g. an "off_t" is a "long long" rather than a "long").
+ savedir() takes on off_t argument, but in grepdir() the parameter
+ is cast to an (unsigned). Well, if an off_t is larger than an int,

+
+2001-02-17 Alain Magloire
+
+ From Guglielmo 'bond' Bondioni :
+ The bug was that using a multi line file that contained REs (one per
+ line), backreferences in the REs were considered global (to the file)
+ and not local (to the line).
+ That is, \1 in line n refers to the first \(.\) in the whole file,
+ rather than in the line itself.
+
+ From Tapani Tarvainen :
+ # Re: grep -e '\(a\)\1' -e '\(b\)\1'
+ That's not the way it should work: multiple -e arguments
+ should be treated as independent patterns and back references
+ should not refer to previous ones.
+
+ From Paul Eggert :
+ GNU grep currently does not issue
+ diagnostics for the following two cases, both of which are erroneous:
+ grep -e '[' -e ']'
+ grep '[
+ ]'
+ POSIX requires a diagnostic in both cases because '[' is not a valid
+ regular expression.
+
+ To overcome those problems, grep no longer pass the concatenate
+ patterns to GNU regex but rather compile each patterns separately
+ and keep the result in an array.
+
+ * src/search.c (patterns): New global variable; a structure array
+ holding the compiled patterns.
+ Declare function prototypes to minimize error.
+ (dfa, kswset, regexbuf, regs): Removed, no longer static globals, but
+ rather fields in patterns[] structure per motif.
+ (Fcompile): Alloc an entry in patterns[] to hold the regex.
+ (Ecompile): Alloc an entry per motif in the patterns[] array.
+ (Gcompile): Likewise.
+ (EGexecute): Loop through of array of patterns[] for a match.
+
+2001-02-17 Alain Magloire
+
+ From Bernd Strieder :
+ # tail -f logfile | grep important | do_something_urgent
+ # tail -f logfile | grep important | do_something_taking_very_long
+ If grep does full buffering in these cases then the urgent operation
+ does not happen as it should in the first case, and in the second case
+ time is lost due to waiting for the buffer to be filled.
+ This is clearly spoken not grep's fault in the first place, but libc's.
+ There is a heuristic in libc that make a stream line-buffered only if a
+ terminal is on the other end. This doesn't take care of the cases where
+ this connection is somehow indirect.
+
+ * src/grep.c (line_buffered): new option variable.
+ (prline): if line_buffered is set fflush() is call.
+ (usage): line_buffered new option.
+ Input from Paul Eggert, doing setvbuf() may not be portable
+ and breaks grep -z.
+
+2001-02-16 Alain Magloire
+
+ Patch from Isamu Hasegawa, for multibyte support.
+ This patch prevent kwset_matcher from following problems.
+ For example, in SJIS encoding, one character has the codepoint 0x895c.
+ So the second byte of the character can match with '\' incorrectly.
+ And in eucJP encoding, there are the characters whose codepoints are
+ 0xa5b9, 0xa5c8. On the other hand, there is one character whose
+ codepoint is 0xb9a5. So 0xb9a5 can match with 2nd byte of 0xa5b9
+ and 1st byte of 0xa5c8.
+
+ * configure.in: Add check for mbrtowc.
+ * src/search.c (check_multibyte_string): new function.
+ Support for multibyte string.
+ (EGexecute): call check_multibyte_string when kwset is set.
+ (Fexecute): call to check_multibyte_string.
+ (MBS_SUPPORT): new macro.
+ (MB_CUR_MAX): new macro.

+2001-02-16 Alain Magloire
+
+ A much requested feature, the possibility to select

+2001-02-09 Alain Magloire
+
+ Patch from Ulrich Drepper to provide hilighting.
+
+ * src/grep.c: New option --color.
+ (color): New static var.
+ (COLOR_OPTION): new constant.
+ (grep_color): new static var.
+ (prline): Now when color is set prline() will call the current matcher
+ to find the offset of the matching string.
+ * src/savedir.c: Take advantage of _DIRENT_HAVE_TYPE if supported.
+ * src/search.c (EGexecute, Fexecute, Pexecute): Take a new argument
+ when doing exact match for the color hiligting.
+
+2000-09-01 Brian Youmans
+
+ * doc/grep.texi: Typo fixes.
+
+2000-08-30 Paul Eggert
+
+ * doc/grep.texi (Usage): Talk about what "grep -r hello *.c"
+ means.
+
+2000-08-20 Paul Eggert
+
+ Handle range expressions correctly even when they match
+ strings with two or more characters.
+
+ * src/dfa.h (CRANGE): New enum value. Comment fix.
+
+ * src/dfa.c: Include <locale.h> if HAVE_SETLOCALE.
+ Include "hard-locale.h".
+ (prtok): Print CRANGE.
+ (hard_LC_COLLATE): New static var.
+ (lex): Return CRANGE when parsing a character range in a hard locale.
+ Don't use strcoll; it's no longer needed and wasn't correct anyway.
+ Use unsigned rather than token to hold unsigned chars.
+ (addtok): Comment fix.
+ (atom): Treat a CRANGE as if it were (.\1), approximately.
+ (dfaparse): Initialize hard_LC_COLLATE.
+
+ * src/Makefile.am (base_sources): Add hard-locale.c, hard-locale.h.
+
+ * src/hard-locale.c, src/hard-locale.h: New files, taken from
+ textutils.
+
+2000-08-20 Paul Eggert
+
+ * tests/Makefile.am (TESTS_ENVIRONMENT): Add LC_ALL=C, since
+ some of the tests assume the C locale.
+
+2000-08-16 Paul Eggert
+
+ * src/search.c (Gcompile, Ecompile): -x overrides -w, for
+ consistency with fgrep. Don't assume that sizes fit in 'int'.
+ Fix comments to match code.
+
+2000-06-06 Paul Eggert
+
+ * src/grep.c (grepdir): Don't look at st_dev when testing for
+ Mingw32 bug.
+
+2000-06-05 Paul Eggert
+
+ Port to Mingw32, based on suggestions from Christian Groessler
+ <cpg@aladdin.de>.
+
+ * src/isdir.c: New file, taken from fileutils.
+
+ * src/Makefile.am (base_sources): Add isdir.c.
+
+ * src/grep.c (grepfile): Use isdir instead of doing it inline.
+ (grepdir): Suppress ancestor check if the directory's inode and device
+ are both zero, as that occurs only on Mingw32 which doesn't support
+ inode or device.
+
+ * src/system.h (isdir): New decl.
+ (is_EISDIR): Depend on HAVE_DIR_EACCES_BUG, not D_OK.
+ Use isdir, not access.
+
+2000-06-02 Paul Eggert
+
+ Problen noted by Gerald Stoller <gerald_stoller@hotmail.com>
+
+ * src/grep.c (main): POSIX says that -q overrides -l, which
+ in turn overrides the other output options. Fix grep to
+ behave that way.
+
+2000-05-27 Paul Eggert
+
+ Simplify and tune the buffer allocation strategy. Do not reserve a
+ large save area: reserve only enough bytes to hold the residue, plus
+ page alignment. Put a newline sentinel before the buffer, for speed
+ when searching backwards for newline.
+
+ * src/grep.c (ubuffer, bufsalloc, PREFERRED_SAVE_FACTOR, page_alloc):
+ Remove. All uses changed.
+ (INITIAL_BUFSIZE): New macro.
+ (reset, fillbuf): Use simpler buffer allocation strategy.
+ (reset): Check for preposterously large pagesize that would cause
+ later calculations to overflow.
+ (fillbuf): Do not resize buffer if there's room at the end for
+ at least one more page. This greatly increases performance when
+ reading from non-regular files that contain no newlines.
+ When growing the buffer, double its size instead of using a
+ more complicated algorithm.
+ (prtext, grep): Speed up by relying on the newline sentinel before the
+ start of the buffer.
+ (grep): When looking backwards for the last newline in a buffer,
+ stop when we hit the residue, since it can't contain a newline.
+ This avoids an O(N**2) algorithm when reading binary data from
+ a pipe. Use a sentinel to speed up the backward search for newline.
+ (nlscan): Undo previous change; it wasn't needed and just complicates
+ and slows down the code a tad.
+
+2000-05-24 Paul Eggert
+
+ Handle very large input counts better. Bug noted by Jim Meyering.
+
+ * src/grep.c (totalcc, totalnl): Use uintmax_t, not off_t.
+ (add_count): New function.
+ (nlscan, prline, grep): Use it to check line and byte count overflows.
+ (nlscan, grep): Don't keep track of counts when not asked to; this
+ avoids unnecessary overflow diagnostics.
+ (print_offset_sep): Now takes args of type uintmax_t and char,
+ not off_t and int.
+
+2000-05-16 Paul Eggert
+
+ Problem reported by Bob Proulx <rwp@hprwp.fc.hp.com>, this patch
+ is base on his finding, with appropriate corrections.
+
+ * src/grep.c (main): Fix bug: -x and -w matched even when no
+ patterns were specified.
+ * tests/empty.sh: Test for -x and -w bug in grep 2.4.2.
+
+2000-04-24 Paul Eggert
+
+ POSIX conformance fixes: grep -q now exits with status zero
+ if an input line is selected, even if an error also occurs.
+ grep -s no longer affects exit status.
+
+ * src/grep.c (suppress_errors): Move definition earlier so
+ that suppressible_error can use it.
+ (suppressible_error): New function.
+ (exit_on_match): New var.
+ (grepbuf): If exit_on_match is nonzero, exit with status zero
+ immediately.
+ (grep, grepfile, grepdir): Invoke suppressible_error.
+ (main): -q sets exit_on_match.
+
+ * doc/grep.1, doc/grep.texi, NEWS:
+ Document -q's behavior as required by POSIX.
+
+ * tests/status.sh:
+ Test for -q and -s behavior as conforming to POSIX.
+
+2000-04-20 Paul Eggert
+
+ * tests/Makefile.am (TESTS_ENVIRONMENT):
+ Set GREP_OPTIONS to the empty string.
+
+2000-04-20 Paul Eggert
+
+ * tests/status.sh: Fix typo: test -b -> test -r.
+
+2000-04-20 Paul Eggert
+
+ * src/dfa.c (lex):
+ Do not assume that [c] is equivalent to [c-c]; this isn't true
+ if LC_COLLATE specifies that some characters are equivalent.
+ (setbit_case_fold): New function.
+ (lex): Use it to simplify the code a bit.
+
+2000-04-17 Paul Eggert
+
+ Do CRLF munging only if HAVE_DOS_FILE_CONTENTS, instead of
+ having it depend on O_BINARY (which leads to incorrect results
+ on BeOS, VMS, and MacOS).
+
+ * bootstrap/Makefile.try (DEFS): Add -DHAVE_DOS_FILE_CONTENTS.
+ * src/system.h (SET_BINARY): Define only if HAVE_DOS_FILE_CONTENTS.
+ (O_BINARY): Do not define.
+
+ * m4/dosfile.m4: Define HAVE_DOS_FILE_CONTENTS if it appears we're
+ using DOS.
+
+ * src/grep.c (undossify_input, fillbuf, dosbuf.c, prline, main):
+ Depend on HAVE_DOS_FILE_CONTENTS, not O_BINARY, when handling CRLF
+ matters.
+ (grepfile, main): Depend on SET_BINARY, not O_BINARY, when
+ handling binary files on hosts that care about text versus binary.
+
+2000-04-17 Paul Eggert
+
+ * lib/getpagesize.h (getpagesize): Define to B_PAGE_SIZE if
+ __BEOS__ is defined. Based on a fix by Bruno Haible
+ <haible@clisp.cons.org>.
+
+2000-04-17 Bruno Haible
+
+ * src/system.h [BeOS]: Ignore O_BINARY.
+ * src/getpagesize.h [BeOS]: Define getpagesize() as B_PAGE_SIZE.
+
+2000-04-10 Paul Eggert
+
+ * doc/grep.1, doc/grep.texi, NEWS: -C now requires an operand.
+ * src/grep.c (short_options, long_options, main, usage): Likewise.
+ (context_length_arg): Renamed from ck_atoi. Now reports an error
+ and exits if the number is out of range for a context length.
+ (get_nondigit_option): New function, which checks for overflow
+ correctly, and which does not parse nonadjacent strings of digits
+ into a single number.
+ (main): Use get_nondigit_option instead of doing the code inline.
+ With -A, -B, and -C, optarg is now guaranteed to be nonzero.
+
+2000-04-08 Paul Eggert
+
+ Now that we know that the input is always terminated by a
+ newline before the matching algorithms see it, clean up the
+ matching algorithms so that they no longer need to modify the
+ input by inserting a sentinel newline, and no longer worry
+ about running off the end of the buffer due to a missing sentinel.
+
+ * src/grep.c (nlscan, prpending, prtext, grepbuf): Do not
+ worry about running off the end of the input buffer, since
+ it's now guaranteed to end in the sentinel newline.
+ * src/search.c (EGexecute, Pexecute): Likewise.
+
+ * src/dfa.c (prtok, dfasyntax, dfaparse, copy, merge, state_index,
+ epsclosure, dfaexec, dfacomp):

+ any inadvertent programming errors made during this conversion.
+ * src/dfa.h (dfacomp, dfaexec, dfaparse): Likewise.

+
+ * src/dfa.c (dfasyntax): Last arg is unsigned char, not int.
+ * src/dfa.h (dfasyntax): Likewise.
+
+ * src/dfa.h (struct dfa): Remove member newlines; no longer needed.
+ * src/dfa.c (build_state, dfaexec, dfafree): Do not worry
+ about special newline state.
+
+ * src/search.c (matchers): Move definition to end of file, so
+ that we don't need forward decls.
+ (lastexact): Remove.
+ (kwset_exact_matches): New var; subsumes old lastexact var.
+ All uses changed.
+
+ * src/dfa.c (index): Remove macro.
+ (REALLOC_IF_NECESSARY): Skip unnecessary test.
+ (tstbit, setbit, clrbit): Declare arg to be unsigned, to help compiler.
+ (copyset, zeroset, equal): Use C builtin primitives, to help compiler.
+ (dfaexec): Do not modify input string.
+ Remove newline parameter; no longer needed.
+ (comsubs): Use strchr, not index.
+
+ * src/grep.h (matchers): Use fixed name size, not pointer (as
+ there's no need for the extra flexibility). All uses changed.
+
+ * src/kwset.h (struct kwsmatch.offset): Renamed from beg, with
+ change of type to size_t. All uses changed.
+
+ * src/grep.c (reset): No longer need kludge for dfaexec. Simplify.
+ (reset, grepbuf): Adjust to new interface for 'execute'.
+ (install_matcher): List is now terminated by null compile,

+
+ * src/search.c (Pcompile): Do not assume newly allocated

+
+2000-04-06 Paul Eggert
+
+ * doc/grep.1, doc/grep.texi, NEWS: Improve the explanation of
+ locale-dependent behavior of range expressions. Mention
+ LC_COLLATE, since this affects range expressions.
+
+2000-03-26 Paul Eggert
+
+ * Makefile.am (ACINCLUDE_INPUTS): Add decl.m4, inttypes_h.m4,

+
+ * configure.in (jm_AC_TYPE_UINTMAX_T, jm_AC_PREREQ_XSTRTOUMAX,

+
+ * src/grep.c: Include xstrtol.h.

+
+2000-03-23 Paul Eggert
+
+ * src/search.c (Pcompile): Add support for NUL bytes in

+
+2000-03-23 Paul Eggert
+
+ * NEWS, doc/grep.1, doc/grep.texi: Change --pcre to --perl-regexp.
+ * src/grep.c (long_options, usage): Likewise.

+ This also removes a possible core dump.
+ Add checks (marked FIXME) for restrictions in pcre.
+ Use pcre_maketables for proper localized behavior.
+ (Pcompile, Pexecute): Use GNU coding style.
+ The argument is a single pattern, not a list of patterns separated
+ by newlines; this is for consistency with grep and egrep.
+ Use pcre_study for speed.
+ (Pexecute): Abort if we lack pcre.
+ Abort if pcre_exec reports an impossible error.
+ Use code similar to the rest of search.c
+ to narrow down to the line we've found.
+
+2000-03-21 Alain Magloire
+
+ * configure.in: added AC_CHECK_LIB(pcre, pcre_exec)
+ * ChangeLog: Typos corrected.
+ * src/search.c: new MACRO HAVE_LIBPCRE
+
+2000-03-21 H.Merijn Brand
+
+ * src/Makefile.am(bin_PROGRAMS): added pgrep and new macro
+ pgrep_SOURCES.
+ * src/search.c: new functions Pcompile() and Pexecute()
+ to support PCRE. Update matcher[] array for pgrep.
+ * src/grep.c: new short and long option --pcre and -P.
+ usage() updated.
+
+2000-03-21 Bastiaan Stougie
+
+ Improvement of the -m or --max-count option. Now works for NUM > 1 and
+ prints trailing context for the last matching line.
+
+ * src/grep.c
+ (after_last_match): Is a new off_t variable that replaces inputhwm
+ to retain the correct input offset even after a call to fillbuf. Note
+ that after_last_match has a different meaning than inputhwm:
+ it always points to the offset in the input of the first byte after
+ the last matching line, and is 0 if no matching line has been found
+ yet.
+ (grep): Print trailing context after the NUMth match when the -m NUM
+ option is used.
+ (grep): Added comment. Should have been commented already.
+ (grepbuf): Now updates outleft correctly. This fixes the bug that the
+ -m NUM option did not stop after NUM lines for NUM greater than 1.
+ (grepbuf, prtext): Now update after_last_match instead of inputhwm.
+ (fillbuf): No longer updates inputhwm.
+ (prpending): When outputting trailing context of the max_count-th
+ matching line, stop at the first matching line.
+ (grepfile): Seek to after_last_match or eof, depending on the values
+ of outleft and bufmapped.
+ (usage): added the -m or --max-count option to the help message.
+ * doc/grep.texi, doc/grep.1: Document the change of the -m option.
+
+2000-03-17 Paul Eggert
+
+ Add new -m or --max-count option, based on a suggestion by
+ Bastiaan Stougie.
+
+ * doc/grep.texi, doc/grep.1: Document it.
+ * src/grep.c (short_options, long_options, main): Add it.
+ (inputhwm): New variable.
+ (fillbuf, prtext, grepbuf): Set it.
+ (bufmapped): Now a macro (defined to zero) if HAVE_MMAP is not defined.
+ (max_count, outleft): New variables.
+ (prtext, grepbuf, grep): Don't output more than outleft lines.
+ (grepfile): If grepping standard input, seek to the limit of what
+ we've read before exiting. This fixes a bug with mmapped input,
+ and is needed for proper -m support.
+ (main): Exit immediately if -m 0 is specified.
+
+2000-03-08 Alain Magloire
+
+ * configure.in: version 2.4.2
+
+2000-03-07 Paul Eggert
+
+ * Make intl subdirectory match fileutils, tar, etc.;
+ see intl/ChangeLog for details.
+
+ * src/getpagesize.h: Reformat to match latest fileutils.
+
+ * src/savedir.c (savedir): Work even if directory size is
+ negative; this can happen with some NFS screwups.
+
+2000-03-03 Jim Meyering
+
+ * regex.m4: Make sure re_compile_pattern accepts patterns like '{1'.
+
+2000-03-02 Alain Magloire
+
+ * 2.4.1 Release
+
+2000-02-25 Paul Eggert
+
+ * configure.in (LIBOBJS): Work around automake 1.4 bug:
+ regex.c wasn't being passed through ansi2knr on pre-ANSI hosts.
+ (ac_use_included_regex): Fix typo in warning.
+ * src/Makefile.am (EXTRA_DIST): Remove regex.c, as the LIBOBJS
+ workaround means that automake now puts regex.c into DIST_COMMON.
+
+2000-02-25 Alain Magloire
+
+ * po/*.po: update of the PO files.
+
+2000-02-22 Eli Zaretskii
+
+ * doc/grep.1: Two small glitches(typos).
+
+2000-02-18 Eli Zaretskii
+
+ * djgpp/config.site (prefix, INSTALL): Use /dev/env/DJDIR instead
+ of ${DJDIR}, so that the produced Makefile's work on any DJGPP
+ installation.
+
+2000-01-30 Alain Magloire
+
+ * doc/grep.1: corrected typo.
+ Noted by Ruslan Ermilov.
+
+2000-01-30 Alain Magloire
+
+ * vms/Makefile.am: added config_vms.h to EXTRA_DIST.
+ * vms/config_vms.h: New File, contains macros specific to VMS and
+ avoid namespace collision with operating system supplied C library.
+ * vms/make.com: Better compiler auto-detection; information for builds
+ on pre-OpenVMS 7.x systems; general overhaul.
+ * src/getpagesize.h: Reinstate support for different pagesizes on
+ VAX and Alpha. Work around problem with DEC C compiler.
+ * src/vms_fab.c: Cast to some assigments; fixed typo argcp vs. argp.
+ * src/vms_fab.h: Added new include files to avoid warnings about
+ undefined function prototypes.
+ Those patches were provided by Martin P.J. Zinser (zinser@decus.de).
+
+2000-01-30 Paul Eggert
+
+ * src/grep.c (main): Update copyright notice.
+
+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

+
+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/vms_fab.c:
+ Use prototypes for function definitions.
+ * src/grep.c (main): Use int counter for default context,

+ (grep): Likewise.
+
+ * doc/grep.texi: Tighten up the text, and fix some minor

+1999-11-01 Alain Magloire
+
+ * src/search.c: Use the more portable [[:alnum:]]

+ * 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

+
+ * src/grep.c (PREFERRED_SAVE_FACTOR): New macro.
+ (reset): If the buffer has already been allocated, set bufsalloc to

+ 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.

+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}.

+
+ * 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 allows them to be floating-point (!).
+
+ * src/vms_fab.h (arr_ptr): ':' -> ';' to fix typo.

+
+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} :

+ (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

+
+ * doc/grep.{1,texi} : -C takes arguments, upgrade manual.

+
+ 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

+
+ 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.

+ 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).

+
+ * 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
+ consider overkill by most.
+
+1998-04-14 Eli Zaretskii
+
+ * djgpp/config.bat: Support file names with multiple dots on all
+ platforms.
+
+ * djgpp/README: Add instructions about file names illegal on

+
+1998-04-13 Alain Magloire
+
+ * 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.

+ buffer. Spotted by Paul Eggert.
+
+1998-03-27 Alain Magloire
+
+ * grep-2.1.1b.tar.gz available.
+
+ * src/regex.c: CLASS_CHAR_MAX set to 256 instead of 6
+ when WCTYPE and WCHAR are not defined. When class names
+ where bigger then 6, it will not detect an error.
+ example '[[:alphabet:]]'.
+
+ * Updated the copyright of the files with emacs.
+ With emacs Jim :).
+
+1998-03-26 Jim Meyering
+
+ * src/dfa.c (IS_WORD_CONSTITUENT): Define.

+ (dfaexec): Likewise.
+
+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.

+ 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
+
+ * src/grep.c: the option "with-filename was not in the arg table.
+ 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.
+

+ That the return status code is ok.
+
+1997-10-10 Andreas Schwab

+ in argv[0], remove the .exe suffix, and downcase the prgram name.
+ [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.

+ Noted by Andrew Beattie <gaffer@tug.com>.
+
+ * grep.c: refuse to scan if the file is a directory.
+ This was causing problems on SUNs. If the directory contains

+ * 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>.
