* dist: don't distribute lib/colorize.cPaul Eggert2014-05-241-1/+2
| | | | | | | | | | | 'configure' creates this file, so it shouldn't be distributed; see: http://bugs.gnu.org/17480 * configure.ac (COLORIZE_SOURCE): New macro. Don't use AC_CONFIG_LINKS for lib/colorize.c. * lib/Makefile.am (nodist_libgreputils_a_SOURCES): New macro. (libgreputils_a_SOURCES): Remove colorize.c. (CLEANFILES): Add colorize.c (colorize.c): New rule.
* build: suppress unsafe-loop-optimizations warningsPaul Eggert2014-04-241-0/+1
| | | | | | | | I ran into one of these while trying out GCC 4.9.0's new -fsanitize=undefined option. The warning told me that GCC didn't do an unsafe optimization, but in 'grep' this is not typically a symptom of a programming error. * configure.ac (WERROR_CFLAGS): Suppress -Wunsafe-loop-optimizations.
* build: reenable some compiler warning optionsJim Meyering2014-04-191-24/+2

* dfa: fix pointer type conversion bugPaul Eggert2014-04-181-1/+0
| | | | | | | | | | | | | The code converted between size_t * and ptrdiff_t *, which wasn't diagnosed by modern x86-64 GCC but isn't portable. Problem reported by Norihiro Tanaka in <http://bugs.gnu.org/17136#31>. * configure.ac (WERROR_CFLAGS): Don't add -Wno-pointer-sign. We want GCC to diagnose pointer signedness problems, as they violate the C standard and other compilers no doubt complain too. * src/dfa.c (struct dfa): Change type of salloc to size_t. (realloc_trans_if_necessary): Convert signed value to size_t before passing its address to x2nrealloc. Changing the type of tralloc to size_t might have led to problems elsewhere.
* maint: update copyright dates for 2014Jim Meyering2014-01-011-1/+1
| | | | Do that by running "make update-copyright".
* maint: avoid automake deprecation warning re ACLOCAL_AMFLAGSJim Meyering2013-10-261-0/+1
| | | | | | * Makefile.am (ACLOCAL_AMFLAGS): Don't use this deprecated variable. * configure.ac (AC_CONFIG_MACRO_DIRS): Use this instead. (AUTOMAKE_OPTIONS): Require automake-1.12.
* build: avoid duplicate -funit-at-a-time etc. optionsPaul Eggert2013-10-251-3/+0
| | | | | | * configure.ac (WERROR_CFLAGS): Don't add -fdiagnostics-show-option and -funit-at-a-time, as Gnulib does that for us now, and we're merely piling on duplicats.
* build: avoid chatter from Automake 1.14Paul Eggert2013-10-201-1/+2
| | | | * configure.ac (AM_INIT_AUTOMAKE): Add subdir-objects.
* build: port shell pattern to Solaris 10Paul Eggert2013-10-201-1/+1
| | | | | | | * configure.ac: Don't use unquoted '^' in a pattern, as this breaks 'configure' on Solaris 10, whose /bin/sh complains about it, which causes 'configure' to exit even before it finds a decent shell. Unix 7th edition shell accepted '^' as an alias for '|'.
* build: port to platforms that predefine _FORTIFY_SOURCEPaul Eggert2013-10-201-1/+1
| | | | | | Problem reported by Brenton Hoff (Bug#15663). * configure.ac (_FORTIFY_SOURCE): Don't define if already defined. This is what Emacs does.
* build: update gettext version to 0.18.2Stefano Lattarini2013-01-111-1/+1
| | | | | | | | | * configure.ac (AM_GNU_GETTEXT_VERSION): Update to 0.18.2. This is necessary to have the gettext-provided m4 files to use AC_PROG_MKDIR_P rather than AM_PROG_MKDIR_P. This latter macro, planned to disappear in Automake 1.14, has already been removed in the development version of Automake, so that, without this change, grep fails to bootstrap with bleeding-edge Automake.
* maint: update all copyright year number rangesJim Meyering2013-01-041-1/+1
| | | | Run "make update-copyright".
* build: go back to AC_PROG_CCPaul Eggert2012-10-241-1/+1
| | | | | | * configure.ac: Go back to using AC_PROG_CC rather than AC_PROG_CC_STDC, as the latter is obsolescent and the Autoconf bug involving the former has been fixed.
* build: use AC_PROG_CC_STDC rather than AC_PROG_CCJim Meyering2012-10-241-1/+1
| | | | | * configure.ac: Use AC_PROG_CC_STDC rather than AC_PROG_CC, to accommodate autoconf-2.69-37+.
* build: default to --enable-gcc-warnings in a git treeEric Blake2012-10-231-1/+5
| | | | | | | | Anyone building from cloned sources can be assumed to have a new enough environment, such that enabling gcc warnings by default will be useful. Tarballs still default to no warnings, and the default can still be overridden with --disable-gcc-warnings. * configure.ac (gl_gcc_warnings): Set default based on environment.
* build: work with new glibc when not optimizingEric Blake2012-09-011-2/+7
| | | | | | | | Starting with glibc 2.15, the system headers refuse to compile unconditional use of FORTIFY_SOURCE if optimization is disabled but -Werror is in effect. * configure.ac (FORTIFY_SOURCE): Make conditional.
* maint: quote 'like this' or "like this", not `like this'Paul Eggert2012-05-061-1/+1
| | | | | | | | | | | | | | | | See <http://lists.gnu.org/archive/html/bug-grep/2012-01/msg00125.html>. * ChangeLog-2009, HACKING, NEWS, README-hacking, cfg.mk, configure.ac: * lib/colorize-w32.c, m4/pcre.m4: * src/Makefile.am, src/dfa.c, src/dosbuf.c, src/main.c: * tests/backref, tests/help-version, tests/tests: In commentary, quote 'like this' or "like this" rather than `like this' or ``like this''. * cfg.mk (old_NEWS_hash): Update due to changed old NEWS. * doc/grep.texi (General Output Control): Quote sample text with @samp, not with `...'. * src/main.c (usage): * tests/help-version: Quote 'like this' rather than `like this' in diagnostics.
* remove lib/ms/Paolo Bonzini2012-01-031-3/+3
| | | | | | | | | | * configure.ac: Create lib/colorize.c as a symbolic link. * lib/colorize-posix.c: New name of lib/colorize-impl.c. * lib/colorize-w32.c: New name of lib/ms/colorize-impl.c. * lib/colorize.c: Delete. * lib/Makefile.am (EXTRA_DIST): Adjust. * .gitignore: Adjust. * cfg.mk: Adjust syntax-check exclusions.
* maint: update all copyright year number rangesJim Meyering2012-01-011-1/+1
| | | | Run "make update-copyright".
* ms: move Microsoft-specific stuff to lib/msPaul Eggert2011-12-311-0/+6
| | | | | | | | | | | | | | | | | | | | | | | * cfg.mk (exclude_file_name_regexp--sc_prohibit_strcmp) (exclude_file_name_regexp--sc_require_config_h) (exclude_file_name_regexp--sc_require_config_h_first): New rules. * lib/colorize.c, lib/colorize.h, lib/colorize-impl.c: * lib/ms/colorize.h, lib/ms/colorize-impl.c: New files. * configure.ac (GREP_SRC_INCLUDES): New macro. * lib/Makefile.am (libgreputils_a_SOURCES): Add colorize.[ch]. (EXTRA_DIST): New macro. * src/Makefile.am (DEFAULT_INCLUDES): New macro. * src/main.c: Include colorize.h. (PR_SGR_START, PR_SGR_END, PR_SGR_START_IF, PR_SGR_END_IF): Now static functions, not macros. (hstdout, norm_attr, w32_console_init, w32_sgr2attr) (w32_clreol) [__MINGW32__]: Move to lib/ms/colorize-impl.c. (pr_sgr_start, pr_sgr_end): Remove; callers changed to use new print_start_colorize, print_end_colorize from colorize.h. (init_colorize): Rename from w32_console_init and move to colorize module; caller changed. (should_colorize): Move to colorize module.
* build: use gnulib's iswctype wcscollJim Meyering2011-12-121-1/+1
| | | | | | | | | * bootstrap.conf (gnulib_modules): Add iswctype and wcscoll. * configure.ac: Remove explicit checks for those functions. * src/mbsupport.h (MBS_SUPPORT): Define to 1 if not already defined. Remove the conditional, now that we're guaranteed by gnulib to have wcscoll and iswctype. Suggested by Alan Hourihane in http://savannah.gnu.org/bugs/?34930
* build: accommodate -Werror=suggest-attribute=pureJim Meyering2011-11-281-0/+2
| | | | | | | | | | | Now that we're using the latest manywarnings module from gnulib, accommodate gcc's -Werror=suggest-attribute=pure option by marking suggested functions with gnulib-defined _GL_ATTRIBUTE_PURE. * src/kwset.c (hasevery): Mark function with pure attribute. (bmexec): Likewise. * src/dfa.c (nsubtoks, istrstr, find_pred, dfamusts): Likewise. * configure.ac: Disable (for lib/) options that seem not to be worth the trouble: -Wunsuffixed-float-constants and -Wformat-nonliteral.
* build: stop distributing gzip'd releases; xz is enoughJim Meyering2011-11-061-1/+1
| | | | | * configure.ac (AM_INIT_AUTOMAKE): Add no-dist-gzip. * NEWS (Build-related): Mention that we're dropping .tar.gz.
* build: use largefile module and update to latest gnulibJim Meyering2011-08-201-1/+0
| | | | | | * configure.ac: Remove AC_SYS_LARGEFILE, subsumed by ... * bootstrap.conf (gnulib_modules): ...this. Use largefile module. * gnulib: Update to latest.
* maint: update copyright year ranges to include 2011Jim Meyering2011-01-031-1/+1
| | | | Run "make update-copyright", so "make syntax-check" works in 2011.
* add comment above fn_grepPaolo Bonzini2010-12-201-1/+10
| | | | * configure.ac (fn_grep): Add comment suggested by Bruno Haible.
* configure: fix M4 quotationPaolo Bonzini2010-11-141-1/+2
| | | | * configure.ac: Add extra brackets around [...] patterns.
* configure: remove dependency on grep that supports long lines and -ePaolo Bonzini2010-11-141-0/+32
| | | | | | * configure.ac (fn_grep): New. Set GREP and EGREP to it, replace with newly-built grep before AC_OUTPUT. Reported by Florin Iucha <http://savannah.gnu.org/bugs/?31646>.
* build: compile gnulib without -Wcast-align to avoid warnings on ARMDmitry V. Levin2010-10-041-0/+1
| | | | * configure.ac (GNULIB_WARN_CFLAGS): Remove -Wcast-align.
* tests: add equiv-classesPaolo Bonzini2010-09-141-0/+1
| | | | | | | * configure.ac (USE_INCLUDED_REGEX): Add Automake conditional. * tests/equiv-classes: New test. * tests/Makefile.am (TESTS): Add it. (XFAIL_TESTS) [USE_INCLUDED_REGEX]: Mark it as expected failure.
* build: use latest gettext: 0.18Jim Meyering2010-05-261-1/+1
| | | | | | | * configure.ac: Use gettext-0.18. * bootstrap.conf (gnulib_modules): Use gettext-h, not gettext. since the latter drags in a depedency on gettext 0.18. Suggested by Bruno Haible.
* maint: fix new argmatch-related syntax-check failuresJim Meyering2010-04-051-2/+2
| | | | | * configure.ac (ARGMATCH_DIE): Use usage(EXIT_FAILURE), not exit(1). * po/POTFILES.in: Add lib/argmatch.c.
* maint: use argmatch, for better --directories=INVAL diagnosticsJim Meyering2010-04-041-0/+6
| | | | | | | | | | | | | | | | | | | | | | Before, you'd see this: grep: unknown directories method Now, you'll see this: grep: invalid argument `INVAL' for `--directories' Valid arguments are: - `read' - `recurse' - `skip' Usage: src/grep [OPTION]... PATTERN [FILE]... Try `src/grep --help' for more information. * bootstrap.conf: Add argmatch. * configure.ac: Define ARGMATCH_DIE and ARGMATCH_DIE_DECL. * src/main.c (directories_type): Define. (directories_args, directories_types) Define. All of the above so we can... (main): Use XARGMATCH. (usage): Declare extern, now that argmatch calls it via ARGMATCH_DIE.
* maint: remove all VMS-related codeJim Meyering2010-04-021-1/+0
| | | | | | | | * configure.ac (AC_CONFIG_FILES): Remove vms/Makefile * Makefile.am (SUBDIRS): Remove vms. * src/Makefile.am (EXTRA_DIST): Remove vms_fab.c and vms_fab.h. * src/vms_fab.c, src/vms_fab.h, vms/make.com: Remove files. * vms/Makefile.am, vms/README, vms/config_vms.h: Likewise.
* build: do not use pkg-config to test for PCRE supportJim Meyering2010-03-261-18/+1
| | | | | | | | | | | | | | * configure.ac: Do not use PKG_PROG_PKG_CONFIG or PKG_CHECK_MODULES. Do not modify CPPFLAGS; that belongs to those who invoke make. Instead, use autoconf's AC_CHECK_HEADERS and AC_SEARCH_LIBS via the new macro, gl_FUNC_PCRE, defined in... * m4/pcre.m4 (gl_FUNC_PCRE): New macro, to handle pcre-related configure-time tests. * src/Makefile.am (grep_LDADD): Use LIB_PCRE, not PCRE_LIBS. * src/pcresearch.c: Test HAVE_LIBPCRE via "#if", not "#ifdef". All other cpp tests of this symbol used "#if". Prompted by a suggestion from Bruno Haible. * NEWS (Build-related): Mention this.
* grep: remove --mmapPaolo Bonzini2010-03-221-1/+0
| | | | | | | | | | | | | | | mmap is a bad idea for sequentially accessed file because it will cause a page fault for every read page. Just consider it a failed experiment, and ignore --mmap while accepting it for backwards compatibility. * configure.ac (AC_FUNC_MMAP): Remove. * doc/grep.texi (Other options): Say --mmap is ignored. * src/grep.c (mmap_option): Remove. (long_options): Do not reference it. (bufmapped, initial_bufoffset): Remove. (reset, fillbuf): Remove HAVE_MMAP code. (grepfile): Remove bufmapped reference. (usage): Say --mmap is ignored.
* build: allow compilation on cygwinEric Blake2010-03-201-1/+1
| | | | | | | | | | | | | | | | | | Gnulib is incompatible with -Wunused-macros. Addtionally, cygwin 1.7.1 coupled with --enable-gcc-warnings tripped on: grep.c: In function 'print_line_middle': grep.c:805: error: array subscript has type 'char' [-Wchar-subscripts] grep.c: In function 'main': grep.c:1833: error: 'optarg' redeclared without dllimport attribute: previous dllimport ignored [-Wattributes] grep.c:1834: error: 'optind' redeclared without dllimport attribute after being referenced with dll linkage * configure.ac (GNULIB_WARN_FLAGS): Disable -Wunused-macros. * src/grep.c (print_line_middle): Use correct type to tolower. (main): Drop useless redeclarations. * .gitignore: Ignore more built files. Signed-off-by: Eric Blake <eblake@redhat.com>
* syntax-check: enable m4-quote-checkPaolo Bonzini2010-03-121-1/+1
| | | | | * cfg.mk (local-checks-to-skip): Enable m4-quote-check. * configure.ac: Fix occurrence.
* build: avoid warnings in gnulib-supplied regex filesJim Meyering2010-02-031-3/+3
| | | | | | | | | | | | | | | | Now that we enable more warnings in lib/, we choose to avoid some via patches applied by bootstrap, using files in the gl/ hierarchy. Other, less-important warnings are avoided simply by turning off the -Wold-style-definition option and using a slightly relaxed set of warnings $(GNULIB_WARN_CFLAGS) in lib/. * gl/lib/regcomp.c.diff: Avoid warnings. * gl/lib/regex_internal.c.diff: Likewise. * gl/lib/regex_internal.h.diff: Likewise. * gl/lib/regexec.c.diff: Likewise. * configure.ac (GNULIB_PORTCHECK): Disable only -Wold-style-definition. * lib/Makefile.am (AM_CFLAGS): Use $(GNULIB_WARN_CFLAGS) rather than the slightly more strict $(WARN_CFLAGS).
* maint: use regex from gnulib, rather than our bit-rotting oneJim Meyering2010-02-031-10/+2
| | | | | | | | | | * bootstrap.conf (gnulib_modules): Add regex. * configure.ac: Don't use jm_INCLUDED_REGEX. Update use of cache variable. * lib/regex.c: Remove file. * lib/regex.h: Likewise. * m4/regex.m4: Likewise. * POTFILES.in: Update to match.
* build: add configure-time --enable-gcc-warnings option; avoid warningsJim Meyering2010-01-061-0/+81
| | | | | | | * bootstrap.conf (gnulib_modules): Add "manywarnings" module. * configure.ac: Add --enable-gcc-warnings, derived from code in bison. * src/Makefile.am (AM_CFLAGS): Set to $(WARN_CFLAGS) $(WERROR_CFLAGS) * lib/Makefile.am (AM_CFLAGS): Likewise, but append.
* build: run gnulib's tests, tooJim Meyering2010-01-051-7/+10
| | | | | | | | * Makefile.am (SUBDIRS): Add gnulib-tests. * gnulib-tests/Makefile.am: New file. * bootstrap.conf (bootstrap_epilogue): New function, from coreutils. (gnulib_tool_option_extras): Define. * configure.ac: Add gnulib-tests/Makefile.
* maint: update all FSF copyright year lists to include 2010Jim Meyering2010-01-011-2/+1
| | | | | | Use this command: git ls-files |grep -vE '^(\..*|COPYING|gnulib)$' |xargs \ env UPDATE_COPYRIGHT_USE_INTERVALS=1 build-aux/update-copyright
* switch to pkg-config for PCRE detectionPaolo Bonzini2009-12-041-5/+6
| | | | | * configure.ac: use pkg-config to detect PCRE * src/Makefile.am (grep_LDADD): link grep with PCRE_LIBS
* build: require automake-1.11, enable silent-rules, parallel tests, xzJim Meyering2009-11-301-2/+4
| | | | | | | * configure.ac (AM_INIT_AUTOMAKE): Create xz-compressed tarballs, not bzip2-compressed ones. Enable automake's silent-rules, parallel tests, and test PASS/FAIL coloring options. Use AC_CONFIG_HEADERS, not AM_CONFIG_HEADER. Quote the argument.
* build: use git-version-gen for inter-release version stringsJim Meyering2009-11-301-1/+4
| | | | * configure.ac (AC_INIT): Use git-version-gen.
* replace AC_DOSFILE with gnulib modulesPaolo Bonzini2009-11-261-5/+1
