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

        <http://savannah.gnu.org/bugs/?func=detailitem&item_id=11579>,

        <http://savannah.gnu.org/patch/?func=detailitem&item_id=1834>,

        <http://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).

2005-11-10  Charles Levert  <charles_levert@gna.org>

        * 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

          "exit_status > 1" instead of "exit_status == 2" in order to

          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 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=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>

        * TODO: Add a few more projects and derived versions to check out.

2005-05-05  Charles Levert  <charles_levert@gna.org>

        * README-alpha: Document grep-commit mailing list.

        * TODO: Add various stuff culled from the mailing list.

2005-05-02  Charles Levert  <charles_levert@gna.org>

        * 78 files: Update FSF's civic address, zip code,

          and citizen relocation code.

2005-04-29  Charles Levert  <charles_levert@gna.org>

        * tests/foad1.sh: Add -b and tricky UTF-8 tests.

          Display LC_ALL when its value is special.  Patch #3962.

        * ABOUT-NLS: Sync with CVS revision 1.9
