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.

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 "--".

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.
