667 which allows the caller to get the index of the matching directory.
669 * make.h (vpath_search): Update prototype.
671 * remake.c (library_search): Implement linker-compatible library
672 search. Use the new VPATH_SEARCH index functionality to keep track

674 lowest directory index.
676 * implicit.c (pattern_search): Pass NULL for the index arguments in
677 the VPATH_SEARCH call.

830 * doc/make.texi (Double-Colon): Mention that pattern rules with
831 double-colons have a different meaning. Savannah bug #27497.
833 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
835 * configh.dos.template: Remove unconditional definition of
836 SYS_SIGLIST_DECLARED.
837 Include <sys/version.h> because ports of GCC 4.3.0 and later no
838 longer include it, so macros like __DJGPP_MINOR__ are no longer
839 defined automatically.
841 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
842 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
843 instead of using the hardcoded ones.
844 (SUBDIRS): doc subdir added.
845 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
846 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
847 create html formated docs. texi2html may not be ported to DOS.
848 (make.info, make.dvi, make.ps, make.html): Make targets depend on
850 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
851 -I switch to look in ./ instead of ./doc.
852 (html): Target depend on html-recursive instead of make_1.html.
853 (make_1.html): Removed.
854 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

858 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
859 (tags-recursive): Allow for more than one subdir in the build
861 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
862 targets. Enter into doc/ to produce the targets.
863 (all-am): $(INFO_DEPS) replaced by info.
865 2009-09-26 Paul Smith <psmith@gnu.org>
867 * read.c (record_files): Use free_ns() to free struct nameseq.
870 * rule.c (freerule): Use free_dep_chain().
872 * read.c (record_files): Free FILENAMES chain for implicit rules.
873 (eval): Static pattern targets go into the string cache.
875 * function.c (string_glob): Free NAME in the nameseq chain.
877 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
879 * implicit.c (pattern_search): Terminate early if we haven't
880 found any rules to try (performance improvement).
882 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
884 * implicit.c (pattern_search): Merge three parallel arrays,
885 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
886 of struct TRYRULE. In the old version the latter two arrays
887 had insufficient length.
889 2009-09-24 Paul Smith <psmith@gnu.org>
891 * implicit.c (pattern_search): Add back support for order-only
892 prerequisites for secondary expansion implicit rules, that were
893 accidentally dropped. If we find a "|", enable order-only mode
894 and set IGNORE_MTIME on all deps that are seen afterward.
895 (pattern_search): Fix memory leaks: for intermediate files where
896 we've already set the file variable and pattern variable sets, be
897 sure to either save or free them as appropriate.
899 2009-09-23 Paul Smith <psmith@gnu.org>
901 Rework the way secondary expansion is stored, for efficiency.
902 This changes secondary expansion so that ONLY WHEN we know we have
903 a possibility of needing secondary expansion, do we defer the
904 secondary expansion. This means more parsing the deps but we use
905 a lot less memory (due to the strcache). Also, this fixes
908 * read.c (eval): Don't parse the dep string here anymore.
909 (record_files): Take the dep argument as an unparsed string. If
910 secondary expansion is enabled AND the prereq string has a '$' in
911 it, then set NEED_2ND_EXPANSION and keep the entire string.
912 Otherwise, parse the dep string here to construct the dep list
913 with the names in the strcache.
915 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
916 duplicate the name string (others are in the strcache).
918 * implicit.c: Remove struct idep and free_idep_chain(): unused.
919 (struct patdeps): New structure to store prereq information.
920 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
921 which prerequisites need expansion, and expand only those.
923 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
924 and enter_prereqs(). split_prereqs() takes a fully-expanded string
925 and splits it into a DEP list, handling order-only prereqs.
926 (enter_prereqs): This function enters a list of DEPs into the file
927 database. If there's a stem defined, expand any pattern chars.
928 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
929 set. Use the above functions.
930 (snap_deps): Only perform second expansion on prereqs that need it,
931 as defined by the NEED_2ND_EXPANSION flag.
932 (print_prereqs): New function to print the prereqs
933 (print_file): Call print_prereqs() rather than print inline.
935 * hash.h (STRING_COMPARE): Take advantage of strcache() by
937 (STRING_N_COMPARE): Ditto.
938 (ISTRING_COMPARE): Ditto.
940 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
941 (parse_file_seq): Return void*

946 * function.c (string_glob): Ditto.
947 * main.c (main): Ditto.
948 * rule.c (install_pattern_rule): Ditto.
950 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
952 2009-09-16 Paul Smith <psmith@gnu.org>
954 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
956 * dep.h: Create alloc_dep() / free_dep() macros.
958 * implicit.c (pattern_search): Take advantage of the new
959 parse_file_seq() to add the directory prefix to each prereq.
961 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
962 all. Avoid reversing chains. Support adding prefixes.
963 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
964 cached/non-cached results.
965 (eval): Remove multi_glob() & invoke new parse_file_seq().
966 * rule.c (install_pattern_rule): Ditto.
967 * main.c (main): Ditto.
968 * implicit.c (pattern_search): Ditto.
969 * function.c (string_glob): Ditto.
970 * file.c (parse_prereqs): Ditto.
971 * default.c (set_default_suffixes): Ditto.
973 * variable.c (parse_variable_definition): Don't run off the end of
974 the string if it ends in whitespace (found with valgrind).
976 * commands.c (set_file_variables): Keep space for all targets in
977 $? if -B is given (found with valgrind).
979 2009-09-15 Paul Smith <psmith@gnu.org>
981 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
982 (xcalloc): Add new function.
983 * make.h: New declarations.
985 * ar.c (ar_glob_match): New calling method for concat().
986 * main.c (main): Ditto.

995 * dir.c (file_impossible): Ditto.
996 * file.c (enter_file): Ditto.
997 * job.c (new_job): Ditto.
998 * read.c (parse_file_seq): Ditto.
999 * vmsfunctions.c (opendir): Ditto.

1014 before looping through them. Fixes Savannah bug #21824.
1016 * doc/make.texi (Wildcard Examples): Clarify when objects is
1017 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1018 (Include): Clarify the behavior of -include.
1019 Fixes Savannah bug #18963.
1021 2009-08-01 Paul Smith <psmith@gnu.org>
1023 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1024 etc. come on the command line. Fixes Savannah bug #27093.
1026 * expand.c (expand_argument): If the argument is large enough use
1027 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1029 * variable.c (do_variable_definition): Avoid using alloca() to
1030 hold values, which can be large. Fixes Savannah bug #23960.
1032 * job.c (new_job): Use memmove() instead of strcpy() since both
1033 pointers are in the same memory block. Fixes Savannah bug #27148.
1034 Patch by Petr Machata.
1036 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1038 * job.c (construct_command_argv_internal): Add "ulimit" and
1039 "unset" to the sh_cmds for Unixy shells.
1041 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1043 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1044 that set make_cv_sys_gnu_glob, so they are also correctly set
1045 when the cache has been populated before.
1047 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1049 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1050 exist, as realpath(3) does where it's supported.
1052 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1054 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1055 (abspath): Support systems that define HAVE_DOS_PATHS (have
1056 drive letters in their file names). Use IS_PATHSEP instead of a
1057 literal '/' comparison. Fixes Savannah bug #26886.
1059 2009-06-14 Paul Smith <psmith@gnu.org>
1061 * remake.c (update_file_1): Remember the original file we marked
1062 as updating, so we can clear that flag again. If we find a target
1063 via vpath, FILE might change.
1064 (check_dep): Ditto. Fixes Savannah bug #13529.
1065 Patch by Reid Madsen <reid.madsen@tek.com>.
1067 2009-06-13 Paul Smith <psmith@gnu.org>
1069 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1070 included by MAKEFILES cannot give default goals.
1071 * read.c (eval): If set_default is not set, pass the no-default-goal
1072 value when we read included makefiles. Fixes Savannah bug #13401.
1074 * ar.c (ar_name): Ensure that targets with empty parens aren't
1075 considered archive member references: archive members must have a
1076 non-empty "member" string. Fixes Savannah bug #18435.
1078 * function.c (string_glob): Rely on multi_glob() to determine
1079 whether files exist or not. Remove call to file_exists_p() which
1080 is not always correct. Fixes Savannah bug #21231.
1081 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1082 then only files that really exist will be returned.
1083 * dep.h: Add new argument to multi_glob().
1084 * rule.c (install_pattern_rule): Ditto.
1085 * read.c (eval): Ditto.
1086 * main.c (main): Ditto.
1087 * implicit.c (pattern_search): Ditto.
1088 * file.c (parse_prereqs): Ditto.
1089 * default.c (set_default_suffixes): Ditto.
1091 2009-06-09 Paul Smith <psmith@gnu.org>
1093 * commands.c (set_file_variables): If always_make_flag is set,
1094 always add the prereq to $?. Fixes Savannah bug #17825.
1096 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1097 to rebuild the deps of all the also_make targets for that file.
1098 Fixes Savannah bug #19108.
1100 * implicit.c (pattern_search): Undo test for is_target, added by
1101 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1102 Rule Search Algorithm". Fixes Savannah bug #17752.
1104 * main.c (clean_jobserver): Clear the jobserver_fds options and
1105 set job_slots to the default when we clean up.
1106 (define_makeflags): Return the new MAKEFLAGS value.
1107 (main): Reset MAKEFLAGS in the environment when we re-exec.
1108 Fixes Savannah bug #18124.
1110 2009-06-08 Paul Smith <psmith@gnu.org>
1112 * read.c (eval): Collapse continuations post-semicolon on target-
1113 specific variables. Fixes Savannah bug #17521.
1115 2009-06-07 Paul Smith <psmith@gnu.org>
1117 * job.c (reap_children): For older systems without waitpid() (are
1118 there any of these left?) run wait(2) inside EINTRLOOP to handle
1119 EINTR errors. Fixes Savannah bug #16401.
1121 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1123 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1125 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1126 not the end, to catch second expansion $(eval ...) defining new
1127 target/prereq relationships during snap_deps.
1128 Fixes Savannah bug #24622.
1130 * read.c (record_files): The second-expansion "f->updating" hack
1131 was not completely correct: if assumed that the target with
1132 commands always had prerequisites; if one didn't then the ordering
1133 was messed up. Fixed for now to use f->updating to decide whether
1134 to preserve the last element in the deps list... but this whole
1135 area of constructing and reversing the deps list is too confusing
1136 and needs to be reworked. Fixes Savannah bug #21198.
1138 2009-06-06 Paul Smith <psmith@gnu.org>
1140 * hash.c (hash_insert): Remove useless test for NULL.
1141 Fixes Savannah bug #21823.
1143 * make.h: Move SET_STACK_SIZE determination to make.h.
1144 * main.c (main): New global variable, STACK_LIMIT, holds the
1145 original stack limit when make was started.
1146 * job.c (start_job_command): Reset the stack limit, if we changed it.
1147 Fixes Savannah bug #22010.
1149 * remake.c (check_dep): Only set the target's state to not-started
1150 if it's not already running. Found this while testing -j10 builds
1151 of glibc: various targets were being rebuilt multiple times.
1152 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1155 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1156 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1159 2009-06-04 Paul Smith <psmith@gnu.org>
1161 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1163 * maintMakefile: Modify access of config and gnulib Savannah
1164 modules to use GIT instead of CVS.
1166 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1167 Fixes Savannah bug #24655.
1169 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1170 this can happen during some invocations of $(eval ...) for example.
1171 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1173 2009-06-02 Paul Smith <psmith@gnu.org>
1175 * configure.in: Check for fileno()
1176 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1177 for the makefile file so invocations of $(shell ...) don't inherit it.
1178 Fixes Savannah bug #24277.
1180 2009-06-01 Paul Smith <psmith@gnu.org>
1182 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1183 expansion was handled incorrectly. Rework the default goal
1184 handling to save the variable only. Remove default_goal_file and
1186 * read.c (eval): Check default_goal_var, not default_goal_name.
1187 * read.c (record_target_var): Don't check default_goal_file here.
1189 2009-05-31 Paul Smith <psmith@gnu.org>
1191 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1192 it, and if the multi_glob() returns nothing (say it expanded to
1193 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1195 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1196 $(and ..) to the reference. Fixes Savannah bug #25694.
1198 * make.1: Be clear that some recipes will be executed even with -n.
1199 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1201 * doc/make.texi (Override Directive): Make more clear how
1202 overrides and appends interact.
1203 Elucidates part of Savannah bug #26207.
1205 * read.c (record_target_var): Don't reset the origin on
1206 target-specific variables; try_variable_definition() will handle
1207 this correctly. Fixes Savannah bug #26207.
1209 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1210 Fixes Savannah bug #25712.
1212 * implicit.c (pattern_search): Keep a pointer to the beginning of
1213 the filename and save that instead of the constructed pointer.
1214 Fixes Savannah bug #26593.
1215 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1217 2009-05-30 Paul Smith <psmith@gnu.org>
1219 * doc/make.texi (Multi-Line): Add a description of the new abilities
1220 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1221 "command sequence" vs. "recipe" syntax.
1222 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1223 after a define, to create variables with those flavors.
1225 2009-05-25 Paul Smith <psmith@gnu.org>
1227 Reworked the parser for variable assignments to allow multiple
1228 modifiers, and in any order. Also allows variable and
1229 prerequisites to be modifier names ('export', 'private', etc.)
1231 * NEWS: Add notes about user-visible changes.
1233 * read.c (struct vmodifiers): Remember what modifiers were seen.
1234 (parse_var_assignment): New function to parse variable assignments.
1235 (eval): Call the new function. Handle variable assignments earlier.
1237 * variable.c (parse_variable_definition): Only parse; don't create var.
1238 (assign_variable_definition): Call parse, then create the var.
1240 2009-05-24 Paul Smith <psmith@gnu.org>
1242 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1243 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1245 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1247 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1248 Fixes Savannah bug #25412.
1250 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1251 prototype for xmalloc.
1252 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1253 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1254 Loop over an array of extensions, instead of duplicating the same
1255 code inline. Use SearchPath followed by CreateFile, instead of
1256 the obsolete OpenFile. Fixes Savannah bug #17277.
1257 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1258 to `find_file'. Fixes Savannah bug #25662.
1260 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1262 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1263 Fixes Savannah bug #20495.
1265 2009-02-28 Ralf Wildenhues <address@hidden>
1267 * doc/make.texi (Instead of Execution): Document interaction of
1268 -t with phony targets.
1270 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1272 Introduce a new keyword "private" which applies to target-specific
1273 variables and prevents their values from being inherited.
1275 * variable.h (struct variable): Add private_var flag to each variable.
1276 Add a flag to specify which list entry switches to the parent target.
1277 * variable.c (define_variable_in_set): Initialize private_var flag.
1278 (lookup_variable): Skip private variables in parent contexts.
1279 (initialize_file_variables): Set next_is_parent appropriately.

1285 2008-10-26 Paul Smith <psmith@gnu.org>
1287 * configure.in: Check for strndup().

1290 * make.h: Rename savestring to xstrndup.
1291 * commands.c (chop_commands): Ditto.
1292 * function.c (func_foreach): Ditto.
1293 * read.c (eval, record_files): Ditto.
1294 * variable.c (define_variable_in_set): Ditto.
1296 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1298 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1301 * w32/subproc/build.bat (GCCBuild): Likewise.
1303 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1305 * job.c (construct_command_argv_internal): Avoid extra backslash
1306 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1309 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1311 * README.W32.template: Remove obsolete text about non-support for
1312 -jN without Unixy shell. Remove obsolete text about not supplying
1313 Visual Studio project files (we do supply them). Modify text to
1314 prefer GCC builds to MSC builds.
1316 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1318 * doc/make.texi (Empty Targets): Fix typo.
1320 2008-03-27 Paul Smith <psmith@gnu.org>
1322 Fix Savannah bug #22379:
1323 * ar.c (ar_glob_match): Zero the allocated structure.
1324 * read.c (parse_file_seq): Ditto.
1326 2008-03-08 Brian Dessent <brian@dessent.net>
1328 * maintMakefile: Update Translation Project location.
1330 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1332 * variable.c (target_environment): Don't use shell_var if its
1333 `value' field is NULL.
1335 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1337 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1339 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1340 (TEXINFOS): Value changed to `doc/make.texi'.
1341 (.SUFFIXES): Use .texi instead of .texinfo.
1342 (make.info, make.dvi): Depend on doc/make.texi.
1343 (.texi.info): New target, instead of ".texinfo.info". Change -I
1344 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1345 (.texi): New target, instead of ".texinfo". Change -I switch to
1346 $(MAKEINFO) to look in doc/. Use --no-split.
1347 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1348 switch to $(MAKEINFO) to look in doc/.
1349 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1350 "*.i[0-9][0-9]" (due to --no-split above).
1351 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1352 (html, make_1.html): New targets.
1353 (.PHONY): Add "html".
1354 (.SUFFIXES): Add .html.
1356 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1358 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1359 HAVE_DECL_SYS_SIGLIST.
1361 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1362 build does not use child_execute_job.
1364 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1365 export the SHELL environment variable to the child.
1367 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1369 * config.h.W32: Include sys/types.h.
1370 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1372 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1373 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1376 2007-11-04 Paul Smith <psmith@gnu.org>
1378 * doc/make.texi: Convert references to "commands", "command
1379 lines", and "command script" to "recipe".
1381 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1384 2007-10-27 Bruno Haible <bruno@clisp.org>
1386 * remake.c (f_mtime): Print time difference values between 100 and
1387 ULONG_MAX in fixed-point notation rather than in exponention notation.
1389 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1391 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1392 a more complex value than a simple shell: if it's not a default
1393 shell now then expand it and see if is a default shell then.
1395 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1397 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1398 pathnames, with const strings.
1399 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1400 from the template (used for building from CVS, not a dist).
1402 2007-10-10 Paul Smith <psmith@gnu.org>
1404 * make.h: Add a prototype for w32_kill() (change suggested by
1405 Yongwei Wu <wuyongwei@gmail.com>).
1407 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1409 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1410 directories in Path.
1412 2007-09-12 Paul Smith <psmith@gnu.org>
1414 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1415 Provided by Diego Biurrun <diego@biurrun.de>
1416 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1417 Provided by Diego Biurrun <diego@biurrun.de>
1419 2007-09-11 Paul Smith <psmith@gnu.org>
1421 * doc/make.texi (Special Variables): Moved this into the "How to
1422 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1423 (MAKEFILE_LIST) No longer a section; this was added into the
1424 "Special Variables" section.
1425 (Rule Introduction): Reference .RECIPEPREFIX.
1426 (Simple Makefile): Ditto.
1427 (Rule Syntax): Ditto.
1428 (Command Syntax): Ditto.
1429 (Error Messages): Ditto.
1431 2007-09-10 Paul Smith <psmith@gnu.org>
1433 * commands.c (print_commands): Don't print an extra line in the
1434 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1436 * read.c (construct_include_path): Add the full string to the cache; we
1437 were chopping the last char.
1439 * NEWS: Announce the .RECIPEPREFIX special variable.
1440 * variable.c (lookup_special_var): Rename from handle_special_var().
1441 (lookup_variable): Call the new name.
1442 (set_special_var): New function: handle setting of special variables.
1443 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1444 (do_variable_definition): Call it.
1445 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1446 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1447 * main.c (main): Create the .RECIPEPREFIX special variable.
1448 * read.c (eval): Remove the cmd_prefix characters from the command
1449 scripts here, so they're not stored in the commands array at all,
1450 rather than waiting and stripping them out during command construction.
1451 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1453 2007-08-15 Paul Smith <psmith@gnu.org>
1455 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1456 file has had the section info removed, so add some to make.texi
1457 before we include it.
1459 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1461 * remake.c (check_dep): Reset the target state for intermediate
1462 files. They might have been considered before but not updated
1463 then (order-only for example) but they will be this time.
1464 Fixes Savannah bug #'s 3330 and 15919.
1466 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1468 Fix Savannah bug #20549:
1469 * function.c (func_shell): Call construct_command_argv with zero
1471 * job.c (construct_command_argv_internal): New argument FLAGS; all
1473 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1475 * job.h (construct_command_argv_internal): Update prototype.
1477 2007-07-13 Paul Smith <psmith@gnu.org>
1479 * file.c (expand_deps): Use variable_buffer as the start of the
1480 buffer, not the original pointer (in case it was reallocated).
1481 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1482 Fixes Savannah bug #20452.
1484 2007-07-04 Paul Smith <psmith@gnu.org>
1486 * (ALL FILES): Update to GPLv3.
1487 * (ALL FILES): Update copyright for 2007.
1489 * main.c (print_version): Move the host type info to the second line.
1491 2007-06-29 Thiemo Seufer <ths@mips.com>
1493 * maintMakefile: Update Translation Project location.
1495 2007-06-13 Paul Smith <psmith@gnu.org>
1497 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1498 "Expansion of a deferred"
1499 Fixes Savannah bug #20018.
1501 * expand.c (variable_expand_for_file): Preserve the value of
1502 reading_file rather than setting it to 0 at the end.
1503 Fixes Savannah bug #20033.
1505 2007-05-11 Paul Smith <psmith@gnu.org>
1507 * job.c (new_job): Add debug info to specify where make found the
1508 command script it is running to build a target.
1509 Fixes Savannah bug #18617.
1511 * default.c (default_suffixes,default_suffix_rules,default_variables):
1512 Add support for Objective C. Fixes Savannah bug #16389.
1513 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1515 * function.c (func_lastword): Initialize p.
1517 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1518 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1519 Dave Korn <dave.korn@artimi.com>
1521 2007-05-08 Paul Smith <psmith@gnu.org>
1523 Fix Savannah bug #19656:
1525 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1527 * make.h: Change all case-insensitive string compares to use
1528 strcasecmp() (from POSIX). If we don't have that but do have one
1529 of the others, define strcasecmp to be one of those instead. If
1530 we don't have any, declare a prototype for our own version.
1532 * misc.c (strcasecmp): Use this if we can't find any native
1533 case-insensitive string comparison function.
1534 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1535 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1537 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1538 strcasecmp() instead of stricmp().
1539 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1540 instead of strcmpi().
1541 * acinclude.m4: Remove the strcasecmp() check from here.
1543 2007-03-21 Paul Smith <psmith@gnu.org>
1545 * configure.in: Don't turn on case-insensitive file system support
1546 if --disable-... is given. Fixes Savannah bug #19348.
1548 2007-03-19 Paul Smith <psmith@gnu.org>
1550 * ALL: Use the strcache for all file name strings, or other
1551 strings which we will never free. The goal is to save memory by
1552 avoiding duplicate copies of strings. However, at the moment this
1553 doesn't save much memory in most situations: due to secondary
1554 expansion we actually save prerequisite lists twice (once before
1555 the secondary expansion, and then again after it's been parsed
1556 into individual file names in the dep list). We will resolve this
1557 in a future change, by doing the parsing up-front for targets
1558 where secondary expansion is not set.
1560 Moving things into the strcache also allows us to use const
1561 pointers in many more places.
1563 2007-01-03 Paul Smith <psmith@gnu.org>
1565 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1566 the function, not just the first. Fixes Savannah bug #18680.
1568 2006-11-18 Paul Smith <psmith@gnu.org>
1570 * strcache.c (strcache_add_len): Don't allocate a new buffer
1571 unless the string is not already nil-terminated. Technically this
1572 is a violation of the standard, since we may be passed an array
1573 that is not long enough to test one past. However, in make this
1574 is never true since we only use nil-terminated strings or
1575 sub-strings thereof.
1577 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1579 * main.c: New global cmd_prefix, defaults to '\t'.

1594 * vpath.c: Partial constification.
1595 * w32/pathstuff.c: Partial constification.

1613 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1614 point to lastword since the example was updated.
1615 Fixes Savannah bug #16304.
1616 (Secondary Expansion): Correct example description.
1617 Fixes Savannah bug #16468.
1618 (Makefile Contents): Clarify that comments cannot appear within
1619 variable references or function calls.
1620 Fixes Savannah bug #16577.
1621 (Special Targets): Clarify how .NOTPARALLEL works in recursion.

1625 prerequisites. Fixes Savannah bug #17880.
1626 (Rule Syntax): "lise" -> "list"
1627 (Multiple Rules): ... -> @dots{}
1628 (Splitting Lines): ditto.
1630 * remake.c (update_file_1): Prereqs that don't exist should be
1631 considered changed, for the purposes of $?.
1632 Fixes Savannah bug #16051.
1634 * make.1: Remove extraneous "+".
1635 Fixes Savannah bug #16652.

1673 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1674 that don't have extended grep.
1675 (cvsclean): Use $(PERL) instead of perl.
1677 2006-04-09 Paul D. Smith <psmith@gnu.org>
1679 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1681 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1682 inner-scope variables don't mask outer-scope variables.
1684 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1687 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1688 values from memory allocation functions: they return void* and so
1689 don't need to be cast. Also remove (char *) casts of arguments to

1704 2006-04-06 Paul D. Smith <psmith@gnu.org>
1706 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1707 require an ISO C 1989 standard compiler and runtime library.

1723 Version 3.81 released.
1725 * NEWS: Updated for 3.81.

1735 support from automake, as described in the Texinfo manual.
1737 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1739 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1740 with lastslash, since the latter points to filename, not to
1742 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1743 Declare and define sh_chars_sh[].
1745 2006-03-23 Paul D. Smith <psmith@gnu.org>
1747 * configure.in: Look for build.sh.in in $srcdir so it will be
1748 built for remote configurations as well.
1750 * Makefile.am: Make sure to clean up build.sh during distclean.
1751 Fixes Savannah bug #16166.
1753 * misc.c (log_access): Takes a const char *.
1754 * function.c (fold_newlines): Takes an unsigned int *.
1755 Both fixes for Savannah bug #16170.
1757 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1759 * implicit.c (pattern_search): Call set_file_variables only
1760 if we have prerequisites that need second expansion. Fixes
1761 Savannah bug #16140.
1763 2006-03-19 Paul D. Smith <psmith@gnu.org>
1765 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1766 memory on hosts that don't support it directly.
1768 * README.cvs: Add information on steps for making a release (to
1769 make sure I don't forget any).
1771 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1773 (die): Cleanup code was removed from here; call the new function.
1774 (main): If we are re-execing, clean up the jobserver first so we
1775 don't leak file descriptors.
1776 Reported by Craig Fithian <craig.fithian@citigroup.com>
1778 2006-03-17 Paul D. Smith <psmith@gnu.org>
1780 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1781 allow multiple concurrent runs.
1782 Patch from Joseph Myers <joseph@codesourcery.com>
1784 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1786 * dep.h (struct dep): Add the stem field.
1787 * misc.c (alloc_dep, free_dep): New functions.
1788 (copy_dep_chain): Copy stem.
1789 (free_dep_chain): Use free_dep.
1790 * read.c (record_files): Store stem in the dependency line.
1791 * file.c (expand_deps): Use stem stored in the dependency line. Use
1792 free_dep_chain instead of free_ns_chain.
1793 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1794 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1795 * main.c (main, handle_non_switch_argument): Ditto.
1796 * remake.c (check_dep): Ditto.

1799 2006-03-14 Paul D. Smith <psmith@gnu.org>
1801 * expand.c (variable_append): Instead of appending everything then
1802 expanding the result, we expand (or not, if it's simple) each part
1804 (allocated_variable_append): Don't expand the final result.
1805 Fixes Savannah bug #15913.
1807 2006-03-09 Paul Smith <psmith@gnu.org>
1809 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1810 listed non-existent files as changed. Turns out there's a bug in
1811 the Linux kernel builds which means that this change causes
1812 everything to rebuild every time. We will re-introduce this fix
1813 in the next release, to give them time to fix their build system.
1814 Fixes Savannah bug #16002.
1815 Introduces Savannah bug #16051.
1817 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1824 locator function find_and_set_default_shell if SHELL came from the

1829 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1830 to be null; don't core in that case.
1832 2006-02-19 Paul D. Smith <psmith@gnu.org>
1834 * commands.c (set_file_variables): Realloc, not malloc, the static
1835 string values to avoid memory leaks.
1837 * expand.c (recursively_expand_for_file): Only set reading_file to
1838 an initialized value.
1840 * implicit.c (pattern_search): We need to make a copy of the stem
1841 if we get it from an intermediate dep, since those get freed.
1843 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1845 (enter_file) [VMS]: Ditto.
1846 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1848 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1850 * job.c (construct_command_argv_internal): Fix last change.
1852 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1853 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1854 the calls to _beginthreadex.
1856 * expand.c (recursively_expand_for_file): Initialize `save' to
1857 prevent compiler warnings.
1859 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1861 * job.c (construct_command_argv_internal): Don't create a temporary
1862 script/batch file if we are under -n. Call _setmode to switch the
1863 script file stream to text mode.
1865 2006-02-17 Paul D. Smith <psmith@gnu.org>
1867 * variable.c (merge_variable_set_lists): Don't try to merge the
1868 global_setlist. Not only is this useless, but it can lead to
1869 circularities in the linked list, if global_setlist->next in one
1870 list gets set to point to another list which also ends in
1872 Fixes Savannah bug #15757.
1874 2006-02-15 Paul D. Smith <psmith@gnu.org>
1876 Fix for Savannah bug #106.
1878 * expand.c (expanding_var): Keep track of which variable we're
1879 expanding. If no variable is being expanded, it's the same as
1881 * make.h (expanding_var): Declare it.
1882 * expand.c (recursively_expand_for_file): Set expanding_var to the
1883 current variable we're expanding, unless there's no file info in
1884 it (could happen if it comes from the command line or a default
1885 variable). Restore it before we exit.
1886 * expand.c (variable_expand_string): Use the expanding_var file
1887 info instead of the reading_file info.
1888 * function.c (check_numeric): Ditto.
1890 (func_wordlist): Ditto.
1891 (func_error): Ditto.
1892 (expand_builtin_function): Ditto.
1893 (handle_function): Ditto.
1895 2006-02-14 Paul D. Smith <psmith@gnu.org>
1897 * read.c (eval): Even if the included filenames expands to the
1898 empty string we still need to free the allocated buffer.
1900 * implicit.c (pattern_search): If we allocated a variable set for
1901 an impossible file, free it.
1902 * variable.c (free_variable_set): New function.
1903 * variable.h: Declare it.
1905 * read.c (read_all_makefiles): Makefile names are kept in the
1906 strcache, so there's never any need to alloc/free them.
1909 * main.c (main): Add "archives" to the .FEATURES variable if
1910 archive support is enabled.
1911 * doc/make.texi (Special Variables): Document it.
1913 2006-02-13 Paul D. Smith <psmith@gnu.org>
1915 * implicit.c (pattern_search): Add checking for DOS pathnames to
1916 the pattern rule target LASTSLASH manipulation.

1921 * (ALL FILES): Updated copyright and license notices.
1923 2006-02-10 Paul D. Smith <psmith@gnu.org>
1925 A new internal capability: the string cache is a read-only cache
1926 of strings, with a hash table interface for fast lookup. Nothing
1927 in the cache will ever be freed, so there's no need for reference
1928 counting, etc. This is the beginning of a full solution for
1929 Savannah bug #15182, but for now we only store makefile names here.
1931 * strcache.c: New file. Implement a read-only string cache.
1932 * make.h: Add prototypes for new functions.
1933 * main.c (initialize_global_hash_tables): Initialize the string cache.
1934 (print_data_base): Print string cache stats.
1935 * read.c (eval_makefile): Use the string cache to store makefile
1936 names. Rewrite the string allocation to be sure we free everything.
1938 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1940 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1941 directory time stamp didn't change, except on FAT filesystems.
1942 Suggested by J. David Bryan <jdbryan@acm.org>.
1944 2006-02-09 Paul D. Smith <psmith@gnu.org>
1946 * function.c (func_or): Implement a short-circuiting OR function.
1947 (func_and): Implement a short-circuiting AND function.
1948 (function_table_init): Update the table with the new functions.
1949 * doc/make.texi (Conditional Functions): Changed the "if" section
1950 to one on general conditional functions. Added documentation for
1951 $(and ...) and $(or ...) functions.
1952 * NEWS: Note new $(and ...) and $(or ...) functions.

1959 one in struct file. Fixes Savannah bug #15641.
1961 2006-02-06 Paul D. Smith <psmith@gnu.org>
1963 * vpath.c (selective_vpath_search): If the file we find has a
1964 timestamp from -o or -W, use that instead of the real time.
1965 * remake.c (f_mtime): If the mtime is a special token from -o or
1966 -W, don't overwrite it with the real mtime.
1967 Fixes Savannah bug #15341.
1969 Updates from Markus Mauhart <qwe123@chello.at>:

1972 (process_signal, process_last_err, process_exit_code): Manage
1973 invalid handle values.
1974 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1975 manage invalid handles; remove them.

1977 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1984 Fixes Savannah bug #15533.
1985 * filedef.h (struct file): Add a new LAST pointer.
1987 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1988 the comparison. For 64-bits systems the result of the subtraction
1989 might not fit into an int. Use comparison instead.
1990 Fixes Savannah bug #15534.
1992 * doc/make.texi: Update the chapter on writing commands to reflect
1993 the changes made in 3.81 for backslash/newline and SHELL handling.
1995 2006-02-01 Paul D. Smith <psmith@gnu.org>
1997 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1998 variable st is not used when it's not initialized.
1999 Patch from Eli Zaretskii <eliz@gnu.org>.

2013 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2015 * remake.c (update_goal_chain): Set g->changed instead of
2016 incrementing it, as it is only 8-bit wide, and could overflow if
2017 many commands got started in update_file.
2019 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
2021 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2022 MAXIMUM_WAIT_OBJECTS.

2039 the shell is not sh.exe.
2041 * job.c (create_batch_file): Renamed from create_batch_filename;
2042 all callers changed. Don't close the temporary file; return its
2043 file descriptor instead. New arg FD allows to return the file
2045 (construct_command_argv_internal): Use _fdopen instead of fopen to
2046 open the batch file.
2048 2006-01-04 Paul D. Smith <psmith@gnu.org>

2071 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2072 disable warnings for MSC.
2073 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2075 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2077 * doc/make.texi (Execution): Add a footnote about changes in
2078 handling of backslash-newline sequences. Mention the differences
2079 on MS-DOS and MS-Windows.
2081 * NEWS: More details about building the MinGW port and a pointer
2082 to README.W32. Fix the section name that describes the new
2083 backward-incompatible processing of backslash-newline sequences.
2084 The special processing of SHELL set to "cmd" is only relevant to
2085 MS-Windows, not MS-DOS.
2087 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2089 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2090 to DWORD, to avoid compiler warnings.

2092 use %ld in format, to avoid compiler warnings.
2094 * doc/make.texi (Special Targets): Fix a typo.
2095 (Appending): Fix cross-reference to Setting.
2096 (Special Variables, Secondary Expansion, File Name Functions)
2097 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2098 periods after a sentence.
2099 (Execution): Add @: after "e.g.".
2100 (Environment): Fix punctuation.
2101 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2102 (Shell Function, Target-specific): Add @: after "vs."
2104 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2106 * read.c (record_target_var): Initialize variable's export field
2107 with v_default instead of leaving it "initialized" by whatever
2108 garbage happened to be on the heap.
2110 2005-12-12 Paul D. Smith <psmith@gnu.org>
2112 * make.1: Fix some display errors and document all existing options.
2113 Patch by Mike Frysinger <vapier@gentoo.org>.
2115 2005-12-11 Paul D. Smith <psmith@gnu.org>
2117 * implicit.c (pattern_search): If 2nd expansion is not set for
2118 this implicit rule, replace the pattern with the stem directly,
2119 and don't re-expand the variable list. Along with the other
2120 .SECONDEXPANSION changes below, fixes bug #13781.
2122 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2124 * implicit.c (pattern_search): Mark other files that this rule
2125 builds as targets so that they are not treated as intermediates
2126 by the pattern rule search algorithm. Fixes bug #13022.
2128 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2130 * remake.c (notice_finished_file): Propagate the change of
2131 modification time to all the double-colon entries only if
2132 it is the last one to be updated. Fixes bug #14334.
2134 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2136 * function.c (func_flavor): Implement the flavor function which
2137 returns the flavor of a variable.
2138 * doc/make.texi (Functions for Transforming Text): Document it.
2139 * NEWS: Add it to the list of new functions.
2141 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2143 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2145 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2146 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2148 2005-10-26 Paul Smith <psmith@gnu.org>
2150 * read.c (record_files): Don't set deps flags if there are no deps.
2151 * maintMakefile: We only need to build the templates when we are
2152 creating a distribution, so don't do it for "all".
2154 2005-10-24 Paul D. Smith <psmith@gnu.org>
2156 Make secondary expansion optional: its enabled by declaring the
2157 special target .SECONDEXPANSION.
2159 * NEWS: Update information on second expansion capabilities.
2160 * doc/make.texi (Secondary Expansion): Document the
2161 .SECONDEXPANSION special target and its behavior.
2162 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2163 prerequisite list was found in a static pattern rule.
2164 (free_dep_chain): Declare a prototype.
2165 * file.c (parse_prereqs): New function: break out some complexity
2167 (expand_deps): If we aren't doing second expansion, replace % with
2168 the stem for static pattern rules. Call the new function.
2169 * filedef.h (parse_prereqs): Declare a prototype.
2170 * implicit.c (pattern_search): Initialize the new staticpattern
2172 * main.c (second_expansion): Declare a global variable to remember
2173 if the special target has been seen. Initialize the new
2174 staticpattern field for prerequisites.
2175 * make.h: Extern for second_expansion.
2176 * misc.c (free_dep_chain): New function: frees a struct dep list.
2177 * read.c (read_all_makefiles): Initialize the staticpattern field.
2178 (eval_makefile): Ditto.
2179 (record_files): Check for the .SECONDEXPANSION target and set
2180 second_expansion global if it's found.
2181 Use the new free_dep_chain() instead of doing it by hand.
2182 Set the staticpattern field for prereqs of static pattern targets.
2184 2005-10-16 Paul D. Smith <psmith@gnu.org>
2186 * main.c (main): Set CURDIR to be a file variable instead of a
2187 default, so that values of CURDIR inherited from the environment
2188 won't override the make value.
2190 2005-09-26 Paul D. Smith <psmith@gnu.org>
2192 * job.c (construct_command_argv_internal): If the line is empty
2193 remember to free the temporary argv strings.
2196 2005-09-16 Paul D. Smith <psmith@gnu.org>
2198 * job.c (start_job_command): The noerror flag is a boolean (single
2199 bit); set it appropriately.
2200 Reported by Mark Eichin <eichin@metacarta.com>
2202 2005-08-29 Paul D. Smith <psmith@gnu.org>
2204 * function.c (func_error): On Windows, output from $(info ...)
2205 seems to come in the wrong order. Try to force it with fflush().
2207 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2209 * read.c (record_files): Move code that sets stem for static
2210 pattern rules out of the if (!two_colon) condition so it is
2211 also executed for two-colon rules. Fixes Savannah bug #13881.
2213 2005-08-08 Paul D. Smith <psmith@gnu.org>
2215 * make.h: Don't test that __STDC__ is non-0. Some compilers
2216 (Windows for example) set it to 0 to denote "ISO C + extensions".
2219 2005-08-07 Paul D. Smith <psmith@gnu.org>
2221 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2222 conditional (slightly different version of a fix from Eli).
2224 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2225 If make is running in parallel without -k and two jobs die in a
2226 row, but not too close to each other, then make will quit without
2227 waiting for the rest of the jobs to die.
2229 * main.c (die): Don't reset err before calling reap_children() the
2230 second time: we still want it to be in the error condition.
2231 * job.c (reap_children): Use a static variable, rather than err,
2232 to control whether or not the error message should be printed.
2234 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2236 * w32/subproc/sub_proc.c: Include signal.h.
2237 (process_pipe_io, process_file_io): Pass a pointer to a local
2238 DWORD variable to GetExitCodeProcess. If the exit code is
2239 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2241 * job.c [WINDOWS32]: Include windows.h.
2242 (main_thread) [WINDOWS32]: New global variable.
2243 (reap_children) [WINDOWS32]: Get the handle for the main thread
2244 and store it in main_thread.
2246 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2247 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2248 doing anything else. When we are done, close the main thread
2249 handle and exit with status 130.
2251 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2253 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2256 * main.c (find_and_set_default_shell): If found a DOSish shell,
2257 set sh_found and the value of default_shell, and report the
2258 findings in debug mode.
2260 * job.c (construct_command_argv_internal): Check unixy_shell, not
2261 no_default_sh_exe, to decide whether to use Unixy or DOSish
2264 * README.W32: Update with info about the MinGW build.
2266 * build_w32.bat: Support MinGW.
2268 * w32/subproc/build.bat: Likewise.
2270 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2271 printing DWORD args.
2273 * function.c (windows32_openpipe): Fix format strings for printing
2276 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2278 (start_job_command): Fix format string for printing the result of
2280 (start_job_command) [WINDOWS32]: Do not define.
2281 (exec_command): Fix format string for printing HANDLE args.
2283 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2284 to avoid compiler warnings.
2285 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2286 (Note: some of these fixes were submitted independently by J. Grant)
2288 2005-07-30 J. Grant <jg@jguk.org>
2290 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2291 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2292 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2294 2005-07-15 Paul Smith <psmith@gnu.org>
2296 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2297 we don't have a POSIX shell, then revert to the old
2298 backslash-newline behavior (where they are stripped).
2301 2005-07-08 Paul D. Smith <psmith@gnu.org>
2303 * config.h.W32.template: Reorder to match the standard config.h,
2304 for easier comparisons.
2305 From J. Grant <jg@jguk.org>
2307 * maintMakefile: Remove .dep_segment before overwriting it, in
2308 case it's not writable or noclobber is set.
2309 * expand.c (variable_expand_string): Cast result of pointer
2310 arithmetic to avoid a warning.
2311 * main.c (switches): Add full-fledged final initializer.
2313 2005-07-06 Paul D. Smith <psmith@gnu.org>
2315 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2316 * signame.c (strsignal): If we found _sys_siglist[] or
2317 __sys_siglist[] use those instead of sys_siglist[].
2318 From Albert Chin <china@thewrittenword.com>
2320 2005-07-04 Paul D. Smith <psmith@gnu.org>
2322 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2323 globfree(); set up to use the GNU versions.
2324 From Martin Zinser <zinser@zinser.no-ip.info>
2326 2005-07-03 Paul D. Smith <psmith@gnu.org>
2328 From J. Grant <jg@jguk.org>:
2330 * README.W32.template: Update the Windows and tested MSVC versions.
2331 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2332 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2333 * build_w32.bat: Ditto.
2334 * w32/subproc/build.bat: Ditto.
2336 2005-06-28 Paul D. Smith <psmith@gnu.org>
2338 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2339 declaration was checked but not present.
2341 2005-06-27 Paul D. Smith <psmith@gnu.org>
2343 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2344 to unsigned long. Fixes Savannah bug #13550.
2346 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2347 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2348 Fixes Savannah bug #13551.
2350 2005-06-26 Paul D. Smith <psmith@gnu.org>
2352 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2353 it if ANSI_STRING is not set.
2355 2005-06-25 Paul D. Smith <psmith@gnu.org>
2357 * read.c (eval): If no filenames are passed to any of the
2358 "include" variants, don't print an error.
2359 * doc/make.texi (Include): Document this.
2360 Fixes Savannah bug #1761.
2362 * job.c (construct_command_argv_internal): Sanitize handling of
2363 backslash/newline pairs according to POSIX: that is, keep the
2364 backslash-newline in the command script, but remove a following
2365 TAB character, if present. In the fast path, make sure that the
2366 behavior matches what the shell would do both inside and outside
2367 of quotes. In the slow path, quote the backslash and put a
2368 literal newline in the string.
2369 Fixes Savannah bug #1332.
2370 * doc/make.texi (Execution): Document the new behavior and give
2372 * NEWS: Make a note of the new behavior.
2374 * make.h [WINDOWS32]: #include <direct.h>.
2375 Fixes Savannah bug #13478.
2377 * remake.c (name_mtime): If the stat() of a file fails and the -L
2378 option was given and the file is a symlink, take the best mtime of
2379 the symlink we can get as the mtime of the file and don't fail.
2380 Fixes Savannah bug #13280.
2382 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2383 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2384 inside a variable reference. Make this function static as it's
2386 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2387 parsing an unexpanded line looking for semicolons.
2388 Fixes Savannah bug #1454.
2389 * misc.c (remove_comments): Move this to read.c and make it static
2390 as it's only used there. Call find_char_unquote() with new arg.
2391 * make.h: Remove prototypes for find_char_unquote() and
2392 remove_comments() since they're static now.
2394 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2395 its export flag and obtain its value. When we need to re-exec,
2396 increment the value and add it into the environment.
2397 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2398 * NEWS: Mention MAKE_RESTARTS.
2399 * main.c (always_make_set): New variable. Change the -B option to
2400 set this one instead.
2401 (main): When checking makefiles, only set always_make_flag if
2402 always_make_set is set AND the restarts flag is 0. When building
2403 normal targets, set it IFF always_make_set is set.
2404 (main): Avoid infinite recursion with -W, too: only set what-if
2405 files to NEW before we check makefiles if we've never restarted
2406 before. If we have restarted, set what-if files to NEW _after_ we
2408 Fixes Savannah bug #7566:
2410 2005-06-17 Paul D. Smith <psmith@gnu.org>
2412 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2413 in the prerequisites list.
2415 2005-06-12 Paul D. Smith <psmith@gnu.org>
2417 Fix Savannah bug # 1328.
2419 * configure.in: Check for atexit().
2420 * misc.c (close_stdout): Test stdout to see if writes to it have
2421 failed. If so, be sure to exit with a non-0 error code. Based on
2422 code found in gnulib.
2423 * make.h: Prototype.
2424 * main.c (main): Install close_stdout() with atexit().
2426 2005-06-10 Paul D. Smith <psmith@gnu.org>
2428 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2430 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2431 headers; make vmsWaitForChildren() static; extern vmsify().
2432 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2433 Don't create child_execute_job() here (it's in vmsjobs.c).
2434 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2436 2005-06-09 Paul D. Smith <psmith@gnu.org>
2438 * variable.c (push_new_variable_scope): File variables point
2439 directly to the global_setlist variable. So, inserting a new
2440 scope in front of that has no effect on those variables: they
2441 don't go through current_variable_set_list. If we're pushing a
2442 scope and the current scope is global, push it "the other way" so
2443 that the new setlist is in the global_setlist variable, and
2444 next points to a new setlist with the global variable set.
2445 (pop_variable_scope): Properly undo a push with the new
2447 Fixes Savannah bug #11913.
2449 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2451 * job.c (reap_children): Don't die of the command failed but
2452 the dontcare flag is set. Fixes Savannah bug #13216.
2454 * implicit.c (pattern_search): When creating a target from
2455 an implicit rule match, lookup pattern target and set precious
2456 flag in a newly created target. Fixes Savannah bug #13218.
2458 2005-05-13 Paul D. Smith <psmith@gnu.org>
2460 Implement "if... else if... endif" syntax.
2462 * read.c (eval): Push all checks for conditional words ("ifeq",
2463 "else", etc.) down into the conditional_line() function.
2464 (conditional_line): Rework to allow "else if..." clause. New
2465 return value -2 for lines which are not conditionals. The
2466 ignoring flag can now also be 2, which means "already parsed a
2467 true branch". If that value is seen no other branch of this
2468 conditional can be considered true. In the else parsing if there
2469 is extra text after the else, invoke conditional_line()
2470 recursively to see if it's another conditional. If not, it's an
2471 error. If so, raise the conditional value to this level instead
2472 of creating a new conditional nesting level. Special check for
2473 "else" and "endif", which aren't allowed on the "else" line.
2474 * doc/make.texi (Conditional Syntax): Document the new syntax.
2476 2005-05-09 Paul D. Smith <psmith@gnu.org>
2478 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2479 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2480 recurses to the w32 directory, even on non-Windows systems. Use
2481 the method suggested in the automake manual.
2482 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2483 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2485 2005-05-07 Paul D. Smith <psmith@gnu.org>
2487 * main.c (die): If we're dying with a fatal error (not that a
2488 command has failed), write back any leftover tokens before we go.
2490 * job.c (set_child_handler_action_flags): If there are jobs
2491 waiting for the load to go down, set an alarm to go off in 1
2492 second. This allows us to wake up from a potentially long-lasting
2493 read() and start a new job if the load has gone down. Turn it off
2495 (job_noop): Dummy signal handler function.
2496 (new_job): Invoke it with the new semantics.
2498 * docs/make.texi: Document secondary expansion. Various cleanups
2501 2005-05-03 Paul D. Smith <psmith@gnu.org>
2503 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2504 the targets which are to ultimately be made are called "goals";
2505 see the GNU make manual. Also, MAKECMDGOALS, etc.
2507 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2508 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2509 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2511 2005-05-02 Paul D. Smith <psmith@gnu.org>
2513 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2514 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2515 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2516 functions to vmsjobs.c. #include it into jobs.c.
2518 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2519 jobserver tokens. I found that this happens when an exported
2520 recursive variable contains a $(shell ...) function reference: in
2521 this situation we could "forget" to write back a token.
2523 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2524 we have. It's not reliable to depend on the number of children in
2525 our linked list so keep a separate count.
2526 (new_job): Check jobserver_tokens rather than children &&
2527 waiting_jobs. Increment jobserver_tokens when we get one.
2528 (free_child): If jobserver_tokens is 0, internal error. If it's
2529 >1, write a token back to the jobserver pipe (we don't write a
2530 token for the "free" job). Decrement jobserver_tokens.
2532 * main.c: Add variable master_job_slots.
2533 (main): Set it to hold the number of jobs requested if we're the
2534 master process, when using the jobserver.
2535 (die): Sanity checks: first test jobserver_tokens to make sure
2536 this process isn't holding any tokens we didn't write back.
2537 Second, if master_job_slots is set count the tokens left in the
2538 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2540 2005-04-24 Paul D. Smith <psmith@gnu.org>
2542 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2543 with -l# can lose jobserver tokens, because waiting jobs are not
2544 consulted properly when checking for the "free" token.
2546 * job.c (free_child): Count waiting_jobs as having tokens.
2547 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2548 handle jobs waiting for the load to drop.
2550 2005-04-23 Paul D. Smith <psmith@gnu.org>
2552 * main.c (main): Be careful to not core if a variable setting in
2553 the environment doesn't contain an '='. This is illegal but can
2554 happen in broken setups.
2555 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2557 2005-04-12 Paul D. Smith <psmith@gnu.org>
2559 The second expansion feature causes significant slowdown. Timing
2560 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2561 read the makefile before the feature, to 11+s to do the same
2562 operations after the feature. Additionally, memory usage
2563 increased drastically. To fix this I added some intelligence that
2564 avoids the overhead of the second expansion unless it's required.
2566 * dep.h: Add a new boolean field, need_2nd_expansion.
2568 * read.c (eval): When creating the struct dep for the target,
2569 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2570 (record_files): If there's a "%" in a static pattern rule, it gets
2571 converted to "$*" so set need_2nd_expansion to 1.
2573 * file.c (expand_deps): Rework to be more efficient. Only perform
2574 initialize_file_variables(), set_file_variables(), and
2575 variable_expand_for_file() if the need_2nd_expansion is set.
2577 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2578 (pattern_search): Ditto.
2579 * main.c (handle_non_switch_argument): Ditto.
2581 * read.c (read_all_makefiles): Ditto.
2582 (eval_makefile): Ditto.
2584 2005-04-07 Paul D. Smith <psmith@gnu.org>
2586 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2587 * variable.c (sync_Path_environment): Ditto.
2588 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2590 * main.c (main): Define the .FEATURES variable.
2591 * NEWS: Announce .FEATURES.
2592 * doc/make.texi (Special Variables): Document .FEATURES.
2594 * remake.c (check_dep): If a file is .PHONY, update it even if
2595 it's marked intermediate. Fixes Savannah bug #12331.
2597 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2599 * file.c (expand_deps): Factor out the second expansion and
2600 prerequisite line parsing logic from snap_deps().
2602 * file.c (snap_deps): Use expand_deps(). Expand and parse
2603 prerequisites of the .SUFFIXES special target first. Fixes
2604 Savannah bug #12320.
2606 2005-03-13 Paul D. Smith <psmith@gnu.org>
2608 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2611 2005-03-11 Paul D. Smith <psmith@gnu.org>
2613 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2614 available, not undefined (from Earnie Boyd).
2616 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2618 * implicit.c (pattern_search): Mark an intermediate target as
2619 precious if it happened to be a prerequisite of some (other)
2620 target. Fixes Savannah bug #12267.
2622 2005-03-09 Paul D. Smith <psmith@gnu.org>
2624 * read.c (eval_makefile): Add alloca(0).
2625 (eval_buffer): Ditto.
2627 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2629 * main.c (main): Use o_file instead of o_default when defining
2630 the .DEFAULT_TARGET special variable.
2631 * read.c (eval): Use define_variable_global() instead of
2632 define_variable() when setting new value for the .DEFAULT_TARGET
2633 special variable. Fixes Savannah bug #12266.
2635 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2637 * imlicit.c (pattern_search): Mark files for which an implicit
2638 rule has been found as targets. Fixes Savannah bug #12202.
2640 2005-03-04 Paul D. Smith <psmith@gnu.org>
2643 * doc/make.texi (Automatic Variables): Document $|.
2645 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2647 * read.c (record_files): Instead of substituting % with
2648 actual stem value in dependency list replace it with $*.
2649 This fixes stem triple expansion bug.
2651 * implicit.c (pattern_search): Copy stem to a separate
2652 buffer and make it a properly terminated string. Assign
2653 this buffer instead of STEM (which is not terminated) to
2654 f->stem. Instead of substituting % with actual stem value
2655 in dependency list replace it with $*. This fixes stem
2656 triple expansion bug.
2658 2005-03-01 Paul D. Smith <psmith@gnu.org>
2660 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2661 on Windows, as it takes a handle not a pid. Just exit.
2662 Fix from patch #3679, provided by Alessandro Vesely.
2664 * configure.in: Update check for sys_siglist[] from autoconf manual.
2665 * signame.c (strsignal): Update to use the new autoconf macro.
2667 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2669 * read.c (record_files): Add a check for the list of prerequisites
2670 of a static pattern rule being empty. Fixes Savannah bug #12180.
2672 2005-02-28 Paul D. Smith <psmith@gnu.org>
2674 * doc/make.texi (Text Functions): Update docs to allow the end
2675 ordinal for $(wordlist ...) to be 0.
2676 * function.c (func_wordlist): Fail if the start ordinal for
2677 $(wordlist ...) is <1. Matches documentation.
2678 Resolves Savannah support request #103195.
2680 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2681 previously we were stopping when !-q, exactly the opposite. This
2682 has been wrong since version 1.34, in 1994!
2683 (update_file): If we got an error don't break out to run more
2684 double-colon rules: just return immediately.
2685 Fixes Savannah bug #7144.
2687 2005-02-27 Paul D. Smith <psmith@gnu.org>
2689 * misc.c (end_of_token): Make argument const.
2690 * make.h: Update prototype.
2692 * function.c (abspath, func_realpath, func_abspath): Use
2693 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2694 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2695 * read.c (record_files): Ditto.
2696 * variable.c (do_variable_definition): Ditto.
2698 * function.c (func_error): Create a new function $(info ...) that
2699 simply prints the message to stdout with no extras.
2700 (function_table_init): Add new function to the table.
2701 * NEWS: Add $(info ...) reference.
2702 * doc/make.texi (Make Control Functions): Document it.
2704 New feature: if the system supports symbolic links, and the user
2705 provides the -L/--check-symlink-time flag, then use the latest
2706 mtime between the symlink(s) and the target file.
2708 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2709 readlink(). If both are available, define MAKE_SYMLINKS.
2710 * main.c: New variable: check_symlink_flag.
2711 (usage): Add a line for -L/--check-symlink-times to the help string.
2712 (switches): Add -L/--check-symlink-times command line argument.
2713 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2714 print a warning and disable it again.
2715 * make.h: Declare check_symlink_flag.
2716 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2717 if the file is a symlink then check each link in the chain and
2718 choose the NEWEST mtime we find as the mtime for the file. The
2719 newest mtime might be the file itself!
2720 * NEWS: Add information about this new feature.
2721 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2723 Avoid core dumps described in Savannah bug # 12124:
2725 * file.c: New variable snapped_deps remember whether we've run
2727 (snap_deps): Set it.
2728 * filedef.h: Extern it.
2729 * read.c (record_files): Check snapped_deps; if it's set then
2730 we're trying to eval a new target/prerequisite relationship from
2731 within a command script, which we don't support. Fatal.
2733 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2735 Implementation of the .DEFAULT_TARGET special variable.
2737 * read.c (eval): If necessary, update default_target_name when
2739 * read.c (record_files): Update default_target_file if
2740 default_target_name has changed.
2741 * main.c (default_target_name): Define.
2742 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2743 default_target_name is set use default_target_file as a root
2745 * filedef.h (default_target_name): Declare.
2746 * dep.h (free_dep_chain):
2747 * misc.c (free_dep_chain): Change to operate on struct nameseq
2748 and change name to free_ns_chain.
2749 * file.c (snap_deps): Update to use free_ns_chain.
2751 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2753 Implementation of the second expansion in explicit rules,
2754 static pattern rules and implicit rules.
2756 * read.c (eval): Refrain from chopping up rule's dependencies.
2757 Store them in a struct dep as a single dependency line. Remove
2758 the code that implements SySV-style automatic variables.
2760 * read.c (record_files): Adjust the code that handles static
2761 pattern rules to expand all percents instead of only the first
2762 one. Reverse the order in which dependencies are stored so that
2763 when the second expansion reverses them again they appear in
2764 the makefile order (with some exceptions, see comments in
2765 the code). Remove the code that implements SySV-style automatic
2768 * file.c (snap_deps): Implement the second expansion and chopping
2769 of dependency lines for explicit rules.
2771 * implicit.c (struct idep): Define an auxiliary data type to hold
2772 implicit rule's dependencies after stem substitution and
2775 * implicit.c (free_idep_chain): Implement.
2777 * implicit.c (get_next_word): Implement helper function for
2778 parsing implicit rule's dependency lines into words taking
2779 into account variable expansion requests. Used in the stem
2782 * implicit.c (pattern_search): Implement the second expansion
2783 for implicit rules. Also fixes bug #12091.
2785 * commands.h (set_file_variables): Declare.
2786 * commands.c (set_file_variables): Remove static specifier.
2788 * dep.h (free_dep_chain): Declare.
2789 * misc.c (free_dep_chain): Implement.
2791 * variable.h (variable_expand_for_file): Declare.
2792 * expand.c (variable_expand_for_file): Remove static specifier.
2794 * make.h (strip_whitespace): Declare.
2795 * function.c (strip_whitespace): Remove static specifier.
2797 2005-02-26 Paul D. Smith <psmith@gnu.org>
2799 * main.c (main): Check for ferror() when reading makefiles from stdin.
2800 Apparently some shells in Windows don't close pipes properly and
2803 2005-02-24 Jonathan Grant <jg@jguk.org>
2805 * configure.in: Add MinGW configuration options, and extra w32 code
2807 * Makefile.am: Add MinGW configuration options, and extra w32 code
2809 * main.c: Determine correct program string (after last \ without .exe).
2810 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2812 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2813 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2814 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2815 environment support.
2817 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2819 * function.c (func_shell): When initializing error_prefix, check
2820 that reading file name is not null. This fixes long-standing
2821 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2823 2005-02-09 Paul D. Smith <psmith@gnu.org>
2825 * maintMakefile: Update the CVS download URL to simplify them.
2826 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2827 downloading the .texi files from Savannah now.
2829 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2831 * main.c (handle_non_switch_argument): Only add variables to
2832 command_variables if they're not already there: duplicate settings
2833 waste space and can be confusing to read.
2835 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2836 this header is never included by non-WINDOWS32 code, and it
2837 requires <config.h> to define which isn't always included first.
2839 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2840 testing MINGW32 versions.
2842 * main.c (log_working_directory): flush stdout to be sure the WD
2843 change is printed before any stderr messages show up.
2845 2005-02-01 Paul D. Smith <psmith@gnu.org>
2847 * maintMakefile (po_repo): Update the GNU translation site URL.
2849 2004-12-01 Paul D. Smith <psmith@gnu.org>
2851 * main.c (main): Change char* env_shell to struct variable shell_var.
2852 * variable.c (target_environment): Use new shell_var.
2854 2004-11-30 Paul D. Smith <psmith@gnu.org>
2856 * configure.in: The old way we avoided creating build.sh from
2857 build.sh.in before build.sh.in exists doesn't work anymore; we
2858 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2859 the help!). This also keeps automake from complaining.
2860 * Makefile.am (README): Add a dummy target so automake won't
2861 complain that this file doesn't exist when we checkout from CVS.
2862 * maintMakefile (.dep_segment): Rewrite this rule since newer
2863 versions of automake don't provide DEP_FILES.
2865 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2867 Implementation of `realpath' and `abspath' built-in functions.
2869 * configure.in: Check for realpath.
2870 * function.c (abspath): Return an absolute file name that does
2871 not contain any `.' or `..' components, nor repeated `/'.
2872 * function.c (func_abspath): For each name call abspath.
2873 * function.c (func_realpath): For each name call realpath
2874 from libc or delegate to abspath if realpath is not available.
2875 * doc/make.texi (Functions for File Names): Document new functions.
2876 * doc/make.texi (Quick Reference): Ditto.
2878 2004-11-28 Paul D. Smith <psmith@gnu.org>
2880 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2881 arguments. Fixes bug #10252.
2883 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2885 * main.c (main): Set SHELL to v_noexport by default. Remember the
2886 original environment setting of SHELL in the env_shell variable.
2887 * main.h: Export new env_shell variable.
2888 * variable.c (target_environment): If we find a v_noexport
2889 variable for SHELL, add a SHELL variable with the env_shell value.
2890 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2891 * doc/make.texi (Variables/Recursion): Ditto.
2893 2004-11-28 Paul D. Smith <psmith@gnu.org>
2895 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2896 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2897 Patch by Alessandro Vesely.
2899 2004-11-12 Paul D. Smith <psmith@gnu.org>
2901 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2902 the command line if it's inside a string.
2903 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2905 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2907 * function.c (func_lastword): New function: return last word
2908 from the list of words.
2909 * doc/make.texi: Document $(lastword ). Fix broken links in
2910 Quick Reference section.
2912 2004-10-06 Paul D. Smith <psmith@gnu.org>
2914 Apply patch from Alessandro Vesely, provided with bug # 9748.
2915 Fix use of tmpnam() to work with Borland C.
2917 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2918 construction of a temporary filename, and call new function
2919 create_batch_filename().
2920 (create_batch_filename) [WINDOWS32]: New function to create a
2923 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2925 * read.c (record_target_var): Expand simple pattern-specific
2927 * variable.c (initialize_file_variables): Do not expand simple
2928 pattern-specific variable.
2930 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2932 * remake.c (update_file_1): When rebuilding makefiles inherit
2933 dontcare flag from a target that triggered update.
2935 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2937 * variable.c (initialize_file_variables): Mark pattern-specific
2938 variable as a per-target and copy export status.
2940 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2942 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2944 * implicit.c (pattern_search): When considering an implicit rule's
2945 prerequisite check that it is actually a target rather then
2946 just an entry in the file hashtable.
2948 2004-09-21 Paul D. Smith <psmith@gnu.org>
2950 * read.c (readstring): Fix some logic errors in backslash handling.
2951 (eval): Remove some unnecessary processing in buffer handling.
2952 (record_target_var): Assert that parse_variable_definition() succeeded.
2953 Reported by: Markus Mauhart <qwe123@chello.at>.
2955 * misc.c: Removed the sindex() function. All instances of this
2956 function were trivially replaceable by the standard strstr()
2957 function, and that function will always have better (or certainly
2958 no worse) performance than the very simple-minded algorithm
2959 sindex() used. This can matter with complex makefiles.
2960 * make.h: Remove the prototype for sindex().
2961 * function.c (subst_expand): Convert sindex() call to strstr().
2962 This means we no longer need to track the TLEN value so remove that.
2963 (func_findstring): Convert sindex() to strstr().
2964 * commands.c (chop_commands): Convert sindex() calls to strstr().
2965 Suggested by: Markus Mauhart <qwe123@chello.at>.
2967 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2968 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2969 If SHELL is set to CMD.EXE then assume it's batch-mode and
2970 non-unixy. I wrote the code differently from the patch, though,
2971 to make it safer. This also resolves bug #9174.
2973 2004-09-20 Paul D. Smith <psmith@gnu.org>
2975 * expand.c (variable_expand_string): Modify to invoke
2976 patsubst_expand() instead of subst_expand(); the latter didn't
2977 handle suffix patterns correctly.
2978 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2979 was used only from variable_expand_string() and is no longer used
2981 (func_subst): Ditto, on call to subst_expand().
2982 (patsubst_expand): Require the percent pointers to point to the
2983 character after the %, not to the % itself.
2984 * read.c (record_files): New call criteria for patsubst_expand().
2985 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2986 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2988 2004-09-19 Paul D. Smith <psmith@gnu.org>
2990 * function.c (subst_expand): Fix a check in by_word: look for a
2991 previous blank if we're beyond the beginning of the string, not
2992 the beginning of the word.
2993 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2995 2004-05-16 Paul D. Smith <psmith@gnu.org>
2997 * remake.c (update_goal_chain): Change the argument specifying
2998 whether we're rebuilding makefiles to be a global variable,
2999 REBUILDING_MAKEFILES.
3000 (complain): Extract the code that complains about no rules to make
3001 a target into a separate function.
3002 (update_file_1): If we tried to rebuild a file during the makefile
3003 rebuild phase and it was dontcare, then no message was printed.
3004 If we then try to build the same file during the normal build,
3005 print a message this time.
3006 (remake_file): Don't complain about un-remake-able files when
3007 we're rebuilding makefiles.
3009 2004-05-11 Paul D. Smith <psmith@gnu.org>
3011 * job.c (construct_command_argv_internal): OS/2 patches from
3012 Andreas Buening <andreas.buening@nexgo.de>.
3014 2004-05-10 Paul D. Smith <psmith@gnu.org>
3016 * remake.c (update_file): Don't walk the double-colon chain unless
3017 this is a double-colon rule. Fix suggested by Boris Kolpackov
3018 <boris@kolpackov.net>.
3020 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3021 * readme.vms: New section describing OpenVMS support and issues.
3022 * default.c (default_variables): Add support for IA64.
3023 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3024 without some privilege aborts make with the error
3025 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3026 pressing Ctrl+Y and the input device is no terminal. The change
3027 catches this error and just continues.
3029 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3031 2004-04-25 Paul D. Smith <psmith@gnu.org>
3033 * commands.c (set_file_variables): Set $< properly in the face of
3034 order-only prerequisites.
3035 Patch from Boris Kolpackov <boris@kolpackov.net>
3037 2004-04-21 Bob Byrnes <byrnes@curl.com>
3039 * main.c (main): Notice failures to remake makefiles.
3041 2004-03-28 Paul D. Smith <psmith@gnu.org>
3043 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3045 * job.c: No default shell for RISC OS.
3046 (load_too_high): Hard-code the return to 1.
3047 (construct_command_argv_internal): No sh_chars or sh_cmds.
3048 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3050 2004-03-20 Paul D. Smith <psmith@gnu.org>
3052 * variable.c (do_variable_definition): Don't append from the
3053 global set if a previous non-appending target-specific variable
3054 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3057 * expand.c (reference_variable): Don't give up on variables with
3058 no value that have the target-specific append flag set: they might
3059 have a value after all. Reported by Oliver Schmidt
3060 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3061 <nikulin@dx1cmd.inp.nsk.su>.
3063 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3064 refer to absolute pathnames in directories that don't exist: some
3065 portion of the makefile could create those directories before we
3066 match the pattern. Fixes bugs #775 and #108.
3068 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3070 * main.c (main): Free makefile_mtimes if we have any.
3071 * README.W32.template: Update documentation for the current status
3072 of the MS-Windows port.
3073 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3074 environment variable is sometimes already defined which causes the
3076 * main.c (debug_signal_handler): Only define this function if
3077 SIGUSR1 is available.
3079 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3081 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3082 * README.OS2.template: Documentation updates.
3083 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3084 link line for safety.
3085 * maintMakefile (build.sh.in): Remove an extraneous ")".
3086 * job.c (child_execute_job): Close saved FDs.
3087 * job.c (exec_command) [OS/2]: exec_command(): If the command
3088 can't be exec'ed and if the shell is not Unix-sh, then try again
3089 with argv = { "cmd", "/c", ... }. Normally, this code is never
3090 reached for the cmd shell unless the command really doesn't exist.
3091 (construct_command_argv_internal) [OS/2]: The code for cmd
3092 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3093 The CMD builtin commands are case insensitive so use strcasecmp().
3095 2004-03-19 Paul D. Smith <psmith@gnu.org>
3097 * read.c (do_define): Re-order line counter increment so the count
3098 is accurate (we were losing one line per define). Reported by
3099 Dave Yost <Dave@Yost.com>.
3101 2004-03-06 Paul D. Smith <psmith@gnu.org>
3103 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3105 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3106 * misc.c (message,error,fatal): Ditto.
3107 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3108 * config.h.W32.template: Ditto.
3109 * config.h-vms.template: Ditto.
3110 * config.ami.template: Ditto.
3112 2004-03-04 Paul D. Smith <psmith@gnu.org>
3114 * README.template: Add a note about broken /bin/sh on SunOS
3115 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3117 * misc.c (message, error, fatal): Don't use "..." if we're using
3118 varargs. ansi2knr should handle this but it doesn't work: it
3119 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3120 done. On many systems (SunOS for example) va_dcl is a #define.
3121 So, force the use of the non-"..." version on pre-ANSI compilers.
3123 * maintMakefile (sign-dist): Create some rules to help automate
3124 the new GNU ftp upload method.
3126 2004-02-24 Paul D. Smith <psmith@gnu.org>
3128 * config.h.W32.template: Add HAVE_STDARG_H
3129 * config.h-vms.template: Ditto.
3130 * config.ami.template: Ditto.
3132 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3134 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3135 * build_w32.bat: Remove extra "+".
3137 2004-02-23 Paul D. Smith <psmith@gnu.org>
3139 * make.h: Create an UNUSED macro to mark unused parameters.
3140 * (many): Clean up warnings by applying UNUSED, fixing
3141 signed/unsigned incompatibilities, etc.
3143 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3145 * filedef.h: Name the command_state enumeration.
3146 * file.c (set_command_state): Use the enumeration in the function
3149 * configure.in: Explicitly set SET_MAKE to empty, to disable
3150 MAKE=make even when no make already exists. Fix bug #3823.
3152 2004-02-22 Paul D. Smith <psmith@gnu.org>
3154 * maintMakefile: Perl script to clean up all non-CVS files. Use
3155 it on all the subdirectories for the cvs-clean target.
3157 * main.c (decode_switches): Require non-empty strings for all our
3158 string command-line options. Fixes Debian bug # 164165.
3160 * configure.in: Check for stdarg.h and varargs.h.
3161 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3162 for printing messages.
3163 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3168 A number of patches for OS/2 support from Andreas Buening
3169 <andreas.buening@nexgo.de>:
3171 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3172 disable the SIGCHLD handler.
3173 (reap_children) [OS/2]: Remove special handling of job_rfd.
3174 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3175 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3176 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3177 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3178 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3181 2004-02-21 Paul D. Smith <psmith@gnu.org>
3183 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3184 <mail@kristov.de> reports that if process_begin() fails we don't
3185 handle the error condition correctly in all cases.
3186 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3187 to have a newline on the message.
3189 * job.c (construct_command_argv_internal): Add "test" to UNIX
3190 sh_cmds[]. Fixes Savannah bug # 7606.
3192 2004-02-04 Paul D. Smith <psmith@gnu.org>
3194 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3195 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3196 Hartmut Becker <Hartmut.Becker@hp.com>.
3198 2004-01-21 Paul D. Smith <psmith@gnu.org>
3200 * job.c (load_too_high): Implement an algorithm to control the
3201 "thundering herd" problem when using -l to control job creation
3202 via the load average. The system only recomputes the load once a
3203 second but we can start many jobs in a second. To solve this we
3204 keep track of the number of jobs started in the last second and
3205 apply a weight to try to guess what a correct load would be.
3206 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3207 Also fixes bug #4693.
3208 (reap_children): Decrease the job count for this second.
3209 (start_job_command): Increase the job count for this second.
3211 * read.c (conditional_line): Expand the text after ifn?def before
3212 checking to see if it's a single word. Fixes bug #7257.
3214 2004-01-09 Paul D. Smith <psmith@gnu.org>
3216 * file.c (print_file): Recurse to print all targets in
3217 double-colon rules. Fixes bug #4518, reported (with patch) by
3218 Andrew Chatham <chatham@google.com>.
3220 2004-01-07 Paul D. Smith <psmith@gnu.org>
3222 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3223 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3224 AC_FUNC_SETVBUF_REVERSED.
3226 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3227 (MAKE Variable): Fix Savannah bug #4898.
3229 * job.c (construct_command_argv_internal): Add "!" to the list of
3230 shell escape chars. POSIX sh allows it to appear before a
3231 command, to negate the exit code. Fixes bug #6404.
3233 * implicit.c (pattern_search): When matching an implicit rule,
3234 remember which dependencies have the ignore_mtime flag set.
3235 Original fix provided in Savannah patch #2349, by Benoit
3236 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3238 2003-11-22 Paul D. Smith <psmith@gnu.org>
3240 * README.W32.template (Outputs): Clarification on -j with
3241 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3244 2003-11-02 Paul D. Smith <psmith@gnu.org>
3246 * function.c (func_if): Strip all the trailing whitespace from the
3247 condition, then don't expand it. Fixed bug # 5798.
3249 * expand.c (recursively_expand_for_file): If we're expanding a
3250 variable with no file context, then use the variable's context.
3253 2003-10-21 Paul D. Smith <psmith@gnu.org>
3255 * main.c (log_working_directory): Add newlines to printf()s.
3257 * README.cvs: Add a note to ignore warnings during autoreconf.
3259 * maintMakefile (po_repo): Set a new URL for PO file updates.
3260 (get-config/config.guess get-config/config.sub): Get these files
3261 from the Savannah config project instead of ftp.gnu.org.
3263 2003-10-05 Paul Eggert <eggert@twinsun.com>
3265 * main.c (main): Avoid potential subscript error if environ has
3268 2003-08-22 Paul D. Smith <psmith@gnu.org>
3270 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3271 systems which don't yet implement the C89 standard :-/.
3273 2003-07-18 Paul D. Smith <psmith@gnu.org>
3275 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3276 [WINDOWS32]: Initialize hash.
3278 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3280 * dir.c (read_dirstream): Provide a workaround for broken versions of
3281 the MinGW dirent structure.
3283 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3285 * w32/include/dirent.h: Add __MINGW32__ filter.
3287 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3289 * make.h: Add global declaration of *make_host.
3290 * main.c (print_usage): Remove local declaration of *make_host.
3291 (print_version): Display "This program built for ..." after Copyright
3294 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3296 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3297 execution of "makeinfo --html make.texi".
3299 2003-04-30 Paul D. Smith <psmith@gnu.org>
3301 * build.template: Make some changes to maybe allow this script to
3302 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3304 * README.OS2.template: New file for OS/2 support. Original
3305 contributed by Andreas Buening.
3306 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3309 2003-04-19 Paul D. Smith <psmith@gnu.org>
3311 Fix bug #1405: allow a target to match multiple pattern-specific
3314 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3315 variable.c, where they've always belonged.
3316 * rule.h: Move the prototypes and struct pattern_var as well.
3317 * variable.c (initialize_file_variables): Invoke
3318 lookup_pattern_var() in a loop, until no more matches are found.
3319 If a match is found, create a new variable set for the target's
3320 pattern variables. Then merge the contents of each matching
3321 pattern variable set into the target's pattern variable set.
3322 (lookup_pattern_var): Change this function to be usable
3323 in a loop. It takes a starting position: if NULL, start at the
3324 beginning; if non-NULL, start with the pattern variable after that
3325 position, and return the next matching pattern.
3326 (create_pattern_var): Create a unique instance of
3327 pattern-specific variables for every definition in the makefile.
3328 Don't combine the same pattern together. This allows us to
3329 process the variable handling properly even when the same pattern
3330 is used multiple times.
3331 (parse_variable_definition): New function: break out the parsing
3332 of a variable definition line from try_variable_definition.
3333 (try_variable_definition): Call parse_variable_definition to
3335 (print_variable_data_base): Print out pattern-specific variables.
3336 * variable.h (struct variable): Remember when a variable is
3337 conditional. Also remember its flavor.
3338 (struct pattern_var): Instead of keeping a variable set, we just
3339 keep a single variable for each pattern.
3340 * read.c (record_target_var): Each pattern variable contains only a
3341 single variable, not a set, so create it properly.
3342 * doc/make.texi (Pattern-specific): Document the new behavior.
3344 2003-04-17 Paul D. Smith <psmith@gnu.org>
3346 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3347 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3348 file/directory naming rules for VMS so I can't tell whether this
3351 2003-04-09 Paul D. Smith <psmith@gnu.org>
3353 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3354 DOS-style pathnames: backslash separators and drive specifiers.
3356 2003-03-28 Paul D. Smith <psmith@gnu.org>
3358 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3359 the intermediate flag on all targets. Fixes bug #2515.
3361 2003-03-24 Paul D. Smith <psmith@gnu.org>
3363 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3364 Upgrade to autoconf 2.57 and automake 1.7.3.
3366 * job.c: More OS/2 changes from Andreas Buening.
3368 * file.c (print_file): Fix variable initialization.
3371 * remake.c (notice_finished_file):
3373 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3374 some calls (like readdir()) return NULL in valid situations
3375 without resetting errno. Fixes bug #2846.
3377 2003-02-25 Paul D. Smith <psmith@gnu.org>
3379 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3381 * job.c (_is_unixy_shell) [OS/2]: New function.
3382 Set default shell to /bin/sh.
3383 (reap_children): Close the job_rfd pipe here since we don't use a
3385 (set_child_handler_action_flags): define this to empty on OS/2.
3386 (start_job_command): Close the jobserver pipe and use
3387 child_execute_job() instead of fork/exec.
3388 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3389 rather than exec'ing, then reconfigure stdin/stdout.
3390 (exec_command): Rewrite to use spawn instead of exec. Return the
3393 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3394 in DOS. Handle the TEMP environment variable as in DOS. Don't
3395 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3396 use -j in DOS mode. Use child_execute_job() instead of
3399 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3402 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3403 prototypes that return values.
3405 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3407 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3408 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3410 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3413 2003-02-24 Paul D. Smith <psmith@gnu.org>
3415 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3416 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3417 (child_execute_job) [VMS]: Handle error status properly.
3418 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3420 * function.c (func_shell): Use EINTRLOOP() while reading from the
3421 subshell pipe (Fixes bug #2502).
3422 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3424 * main.c (main): Ditto.
3426 2003-01-30 Paul D. Smith <psmith@gnu.org>
3428 * read.c (eval): eval() was not fully reentrant, because the
3429 collapsed buffer was static. Change it to be an automatic
3430 variable so that eval() can be invoked recursively.
3432 (eval): Apply patch # 1022: fix memory reference error on long
3433 target-specific variable lines.
3434 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3436 * function.c (check_numeric): Combine the is_numeric() function
3437 into this function, since it's only called from one place.
3438 Constify this function. Have it print the incorrect string in the
3439 error message. Fixes bug #2407.
3440 (strip_whitespace): Constify.
3441 (func_if): Constify.
3442 * expand.c (expand_argument): Constify.
3444 2003-01-29 Paul D. Smith <psmith@gnu.org>
3446 Fix bug # 2169, also reported by other people on various systems.
3448 * make.h: Some systems, such as Solaris and PTX, do not fully
3449 implement POSIX-compliant SA_RESTART functionality; important
3450 system calls like stat() and readdir() can still fail with EINTR
3451 even if SA_RESTART has been set on the signal handler. So,
3452 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3453 EINTR for system calls which return -1 or 0 (NULL), respectively,
3455 Also, remove the old atomic_stat()/atomic_readdir() and
3456 HAVE_BROKEN_RESTART handling.
3458 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3460 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3461 * remake.c (touch_file): Ditto.
3463 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3464 * read.c (construct_include_path): Ditto.
3465 * remake.c (name_mtime): Ditto.
3466 * vpath.c (selective_vpath_search): Ditto.
3467 * dir.c (find_directory): Ditto.
3468 (local_stat): Ditto.
3469 (find_directory): Use ENULLLOOP() to wrap opendir().
3470 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3472 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3473 atomic_readdir() handling.
3475 2003-01-22 Paul D. Smith <psmith@gnu.org>
3477 * function.c (func_call): Fix Bug #1744. If we're inside a
3478 recursive invocation of $(call ...), mask any of the outer
3479 invocation's arguments that aren't used by this one, so that this
3480 invocation doesn't "inherit" them accidentally.
3482 2002-12-05 Paul D. Smith <psmith@gnu.org>
3484 * function.c (subst_expand): Valery Khamenia reported a
3485 pathological performance hit when doing substitutions on very
3486 large values with lots of words: turns out we were invoking
3487 strlen() a ridiculous number of times. Instead of having each
3488 call to sindex() call strlen() again, keep track of how much of
3489 the text we've seen and pass the length to sindex().
3491 2002-11-19 Paul D. Smith <psmith@gnu.org>
3493 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3496 2002-11-16 Paul D. Smith <psmith@gnu.org>
3498 * NMakefile.template (OBJS): Add hash.c object file.
3499 * SMakefile.template (srcs): Ditto.
3500 * Makefile.ami (objs): Ditto.
3501 * build_w32.bat: Ditto.
3503 * Makefile.DOS.template: Remove extra dependencies.
3505 2002-10-25 Paul D. Smith <psmith@gnu.org>
3507 * expand.c (install_variable_buffer): New function. Install a new
3508 variable_buffer context and return the previous one.
3509 (restore_variable_buffer): New function. Free the current
3510 variable_buffer context and put a previously saved one back.
3511 * variable.h: Prototypes for {install,restore}_variable_buffer.
3512 * function.c (func_eval): Push a new variable_buffer context
3513 before we eval, then restore the old one when we're done.
3516 * read.c (install_conditionals): New function. Install a new
3517 conditional context and return the previous one.
3518 (restore_conditionals): New function. Free the current
3519 conditional context and put a previously saved one back.
3520 (eval): Use the {install,restore}_conditionals for "include"
3522 (eval_buffer): Use {install,restore}_conditionals to preserve the
3523 present conditional state before we evaluate the buffer.
3526 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3528 (Recursion): Add a variable index entry for CURDIR.
3530 * README.cvs: Update to appropriate versions.
3531 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3532 don't need to copy loadavg.c: automake is smart enough to create
3533 it for me. Still have a bug in automake related to ansi2knr tho.
3535 2002-10-14 Paul D. Smith <psmith@gnu.org>
3537 * remake.c (notice_finished_file): Only touch targets if they have
3538 at least one command (as per POSIX). Resolve Bug #1418.
3540 * *.c: Convert to using ANSI C-style function definitions.
3541 * Makefile.am: Enable the ansi2knr feature of automake.
3542 * configure.in: ditto.
3544 2002-10-13 Paul D. Smith <psmith@gnu.org>
3546 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3547 for automatic variable values like $^, etc. In the case of very
3548 large lists of prerequisites this causes problems. Instead reuse
3549 a static buffer (resizeable) for each variable.
3551 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3552 target-specific variable definitions. Check for it and set an
3554 (record_target_var): Set the export field to v_export if the
3555 "exported" flag is set.
3556 * doc/make.texi (Target-specific): Document the ability to use
3559 * doc/make.texi: Change the name of the section on automatic
3560 variables from "Automatic" to "Automatic Variables". Added text
3561 clarifying the scope of automatic variables.
3563 2002-10-04 Paul D. Smith <psmith@gnu.org>
3565 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3567 (record_files): Ditto.
3569 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3570 the search for the '=' to only within the enclosing parens.
3572 2002-10-03 Paul D. Smith <psmith@gnu.org>
3574 Version 3.80 released.
3576 * dir.c: Change hash functions to use K&R function definition style.
3577 * function.c: Ditto.
3579 * variable.c: Ditto.
3581 Update to automake 1.7.
3583 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3584 (pdf): Remove this target as automake now provides one.
3586 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3588 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3590 * makefile.com: Updates for GNU make 3.80.
3591 * makefile.vms: Ditto.
3593 2002-09-23 Paul D. Smith <psmith@gnu.org>
3595 * read.c (enum make_word_type): Remove w_comment.
3596 (get_next_mword): Don't treat comment characters as special; where
3597 this function is used we will never see a comment (it's stripped
3598 before we get here) and treating comments specially means that
3599 targets like "foo\#bar" aren't handled properly.
3601 2002-09-18 Paul D. Smith <psmith@gnu.org>
3603 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3605 * read.c (eval): Expansion of arguments to export/unexport was
3606 ignoring all arguments after the first one. Change the algorithm
3607 to expand the whole line once, then parse the results.
3609 2002-09-17 Paul D. Smith <psmith@gnu.org>
3611 Fix Bug #940 (plus another bug I found while looking at this):
3613 * read.c (record_target_var): enter_file() will add a new entry if
3614 it's a double-colon target: we don't want to do that in this
3615 situation. Invoke lookup_file() and only enter_file() if it does
3616 not already exist. If the file we get back is a double-colon then
3617 add this variable to the "root" double-colon target.
3619 * variable.c (initialize_file_variables): If this file is a
3620 double-colon target but is not the "root" target, then initialize
3621 the root and make the root's variable list the parent of our
3624 2002-09-13 Paul D. Smith <psmith@gnu.org>
3626 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3628 * hash.c (round_up_2): Get rid of a warning.
3630 2002-09-12 Paul D. Smith <psmith@gnu.org>
3632 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3633 so it doesn't complain about getloadavg.c.
3635 * commands.c (set_file_variables): Make sure we always alloca() at
3636 least 1 character for the value of $? (for '\0').
3638 2002-09-11 Paul D. Smith <psmith@gnu.org>
3640 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3641 macro to use RESULT instead of the incorrect _RESULT_.
3643 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3644 and atomic_readdir(). We need to #include dirent.h to get this to
3646 * misc.c (atomic_readdir): Fix typos.
3648 2002-09-10 Paul D. Smith <psmith@gnu.org>
3650 * read.c (eval): Expand variable lists given to export and
3651 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3652 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3654 * doc/make.texi (Variables/Recursion): Document this.
3655 (Conditional Syntax): And here.
3657 2002-09-09 Paul D. Smith <psmith@gnu.org>
3659 * configure.in: Check for memmove().
3661 2002-09-07 Paul D. Smith <psmith@gnu.org>
3663 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3664 Michael Sterrett <msterret@coat.com> reports that while it has
3665 SA_RESTART, it does not work properly.
3667 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3668 that invokes stat() and loops to do it again if it returns EINTR.
3669 (atomic_readdir): Ditto, with readdir().
3671 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3672 and readdir() to atomic_stat() and atomic_readdir().
3674 2002-09-04 Paul D. Smith <psmith@gnu.org>
3676 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3677 reports that GNU make sometimes doesn't recognize that targets can
3678 be made, when directories can be created as prerequisites. He
3679 reports that changing the order of predicates in the DEP->changed
3680 flag test so that lookup_file() is always performed, solves this
3683 2002-08-08 Paul D. Smith <psmith@gnu.org>
3685 * configure.in: Require a newer version of gettext.
3687 * misc.c (perror_with_name): Translate the format string (for
3688 right-to-left language support).
3689 (pfatal_with_name): Ditto.
3691 * main.c: Create a static array of strings to store the usage
3692 text. This is done to facilitate translations.

3694 (switches): Remove values for obsolete fields.
3695 (print_usage): Print each element of the usage array.
3697 * hash.c: Change function definitions to be K&R style.
3699 2002-08-02 Paul D. Smith <psmith@gnu.org>
3701 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3702 this one because it's too hard to get right. We'll look at it for
3704 * main.c (main): Don't create the .TARGETS variable.
3705 * variable.c (handle_special_var): Don't handle .TARGETS.
3707 2002-08-01 Paul D. Smith <psmith@gnu.org>

3712 (always_make_flag): New flag.
3713 * make.h: Extern always_make_flag.
3714 * remake.c (update_file_1): Check always_make_flag; if it's set we
3715 will always rebuild any target we can, even if none of its
3716 prerequisites are newer.
3719 * doc/make.texi (Shell Function): Make it clear that make
3720 variables marked as "export" are not passed to instances of the
3723 Add new introspection variable .VARIABLES and .TARGETS.
3725 * variable.c (handle_special_var): New function. If the variable
3726 reference passed in is "special" (.VARIABLES or .TARGETS),
3727 calculate the new value if necessary. .VARIABLES is handled here:
3728 walk through the hash of defined variables and construct a value
3729 which is a list of the names. .TARGETS is handled by
3730 build_target_list().
3731 (lookup_variable): Invoke handle_special_var().
3732 * file.c (build_target_list): Walk through the hask of known files
3733 and construct a list of the names of all the ones marked as
3735 * main.c (main): Initialize them to empty (and as simple variables).
3736 * doc/make.texi (Special Variables): Document them.
3737 * NEWS: Mention them.
3739 * variable.h (struct variable): Add a new flag "exportable" which
3740 is true if the variable name is valid for export.
3741 * variable.c (define_variable_in_set): Set "exportable" when a new
3742 variable is defined.
3743 (target_environment): Use the "exportable" flag instead of
3744 re-checking the name here... an efficiency improvement.
3746 2002-07-31 Paul D. Smith <psmith@gnu.org>
3748 * config.h-vms.template: Updates to build on VMS. Thanks to
3749 Brian_Benning@aksteel.com for helping verify the build.
3750 * makefile.com: Build the new hash.c file.
3751 * hash.h: Use strcpmi(), not stricmp(), in the
3752 HAVE_CASE_INSENSITIVE_FS case.
3754 2002-07-30 Paul D. Smith <psmith@gnu.org>
3756 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3757 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3758 Reported by <Brian_Benning@aksteel.com>.
3760 2002-07-10 Paul D. Smith <psmith@gnu.org>
3762 * variable.c (pop_variable_scope): Remove variable made unused by
3763 new hash infrastructure.
3764 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3765 comparisons as well as name comparisons.
3766 * variable.h: Add a prototype for new hash_init_function_table().
3767 * file.c (lookup_file): Remove variables made unused by new hash
3769 * dir.c (directory_contents_hash_2): Missing return of hash value.
3770 (dir_contents_file_exists_p): Remove variables made unused by new
3771 hash infrastructure.
3774 Installed Greg McGary's integration of the hash functions from the
3775 GNU id-utils package:
3777 2002-07-10 Greg McGary <greg@mcgary.org>
3779 * scripts/functions/filter-out: Add literals to to the
3780 pattern space in order to add complexity, and trigger
3781 use of an internal hash table. Fix documentation strings.
3782 * scripts/targets/INTERMEDIATE: Reverse order of files
3783 passed to expected `rm' command.
3785 2002-07-10 Greg McGary <greg@mcgary.org>

3877 2002-07-10 Paul D. Smith <psmith@gnu.org>
3879 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3880 prerequisite list. A real SysV make will expand the entire
3881 prerequisites list _twice_: we don't do that as it's a big
3882 backward-compatibility problem. We only replace those specific
3885 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3886 references left in the list of prerequisites. Check for .POSIX as
3887 we record targets, so we can disable non-POSIX behavior while
3888 reading makefiles as well as running them.
3889 (eval): Check the prerequisite list to see if we have anything
3890 that looks like a SysV prerequisite variable reference.
3892 2002-07-09 Paul D. Smith <psmith@gnu.org>
3894 * doc/make.texi (Prerequisite Types): Add a new section describing
3895 order-only prerequisites.
3897 * read.c (uniquize_deps): If we have the same file as both a
3898 normal and order-only prereq, get rid of the order-only prereq,
3899 since the normal one supersedes it.
3901 2002-07-08 Paul D. Smith <psmith@gnu.org>
3903 * AUTHORS: Added Greg McGary to the AUTHORS file.
3904 * NEWS: Blurbed order-only prerequisites.
3905 * file.c (print_file): Show order-only deps properly when printing
3908 * maintMakefile: Add "update" targets for wget'ing the latest
3909 versions of various external files. Taken from Makefile.maint in
3912 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3913 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3915 2002-07-07 Paul D. Smith <psmith@gnu.org>
3917 * po/*.po: Remove. We'll use wget to retrieve them at release
3920 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3921 rather than a shell you get an exception. Make sure we look up
3922 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3924 * remake.c (notice_finished_file): Fix handling of -t flag.
3925 Patch provided by Henning Makholm <henning@makholm.net>.
3927 * implicit.c (pattern_search): Some systems apparently run short
3928 of stack space, and using alloca() in this function caused an
3929 overrun. I modified it to use xmalloc() on the two variables
3930 which seemed like they might get large. Fixes Bug #476.
3932 * main.c (print_version): Update copyright notice to conform with
3934 (print_usage): Update help output.
3936 * function.c (func_eval): Create a new make function, $(eval
3937 ...). Expand the arguments, put them into a buffer, then invoke
3938 eval_buffer() on the resulting string.
3939 (func_quote): Create a new function, $(quote VARNAME). Inserts
3940 the value of the variable VARNAME without expanding it any
3943 * read.c (struct ebuffer): Change the linebuffer structure to an
3944 "eval buffer", which can be either a file or a buffer.
3945 (eval_makefile): Move the code in the old read_makefile() which
3946 located a makefile into here: create a struct ebuffer with that
3947 information. Have it invoke the new function eval() with that
3949 (eval_buffer): Create a new function that creates a struct ebuffer
3950 that holds a string buffer instead of a file. Have it invoke
3951 eval() with that ebuffer.
3952 (eval): New function that contains the guts of the old
3953 read_makefile() function: this function parses makefiles. Obtains
3954 data to parse from the provided ebuffer. Some modifications to
3955 make the flow of the function cleaner and clearer. Still could
3956 use some work here...
3957 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3958 contents of the define/endef variable from the ebuffer.
3959 (readstring): Read the next line from a string-style ebuffer.
3960 (readline): Read the next line from an ebuffer. If it's a string
3961 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3964 * dep.h (eval_buffer): Prototype eval_buffer();
3966 * variable.c (do_variable_definition): Make sure that all
3967 non-target-specific variables are registered in the global set.
3968 If we're invoked from an $(eval ...) we might be inside a $(call
3969 ...) or other function which has pushed a variable scope; we still
3970 want to define our variables from evaluated makefile code in the
3973 2002-07-03 Greg McGary <greg@mcgary.org>
3975 * dep.h (struct dep) [ignore_mtime]: New member.
3976 [changed]: convert to a bitfield.
3977 * implicit.c (pattern_search): Zero ignore_mtime.
3978 * main.c (main, handle_non_switch_argument): Likewise.
3979 * rule.c (convert_suffix_rule): Likewise.
3980 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3981 (read_makefile): Parse '|' in prerequisite list.
3982 (uniquize_deps): Consider ignore_mtime when comparing deps.
3983 * remake.c (update_file_1, check_dep): Don't force remake for
3984 dependencies that have d->ignore_mtime.
3985 * commands.c (FILE_LIST_SEPARATOR): New constant.
3986 (set_file_variables): Don't include a
3987 prerequisite in $+, $^ or $? if d->ignore_mtime.
3990 2002-06-18 Paul D. Smith <psmith@gnu.org>
3992 * make.texinfo: Updates for next revision. New date/rev/etc.
3993 Recreate all Info menus. Change license on the manual to the GNU
3994 Free Documentation License. A number of typos.
3995 (Variables Simplify): Don't use "-" before it's defined.
3996 (Automatic Prerequisites): Rewrite the target example to work
3997 properly if the compile fails. Remove incorrect comments about
3998 how "set -e" behaves.
3999 (Text Functions): Move the "word", "wordlist", "words", and
4000 "firstword" functions here, from "File Name Functions".
4001 * make-stds.texi: Update from latest GNU version.
4002 * fdl.texi: (created) Import the latest GNU version.
4004 2002-06-06 Paul D. Smith <psmith@gnu.org>
4006 * variable.c (do_variable_definition): New function: extract the
4007 part of try_variable_definition() that actually sets the value
4008 into a separate function.
4009 (try_variable_definition): Call do_variable_definition() after
4010 parsing the variable definition string.
4011 (define_variable_in_set): Make the name argument const.
4013 * variable.h (enum variable_flavor): Make public.
4014 (do_variable_definition): Create prototype.
4016 * read.c (read_all_makefiles): Create a new built-in variable,
4018 (read_makefile): Add each makefile read in to this variable value.
4020 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4022 * Makefile.DOS.template: Tweak according to changes in the
4023 distribution. Add back the dependencies of *.o files.
4025 * configh.dos.template: Synchronize with config.h.in.
4027 2002-05-09 Paul D. Smith <psmith@gnu.org>
4029 * file.c (file_timestamp_now): Use K&R function declaration.
4031 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4032 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4033 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4034 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4035 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4036 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4037 nlist.n_name is a pointer rather than an array.
4039 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4040 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4041 * configure.in: Use it instead of the old version.
4043 * main.c (main): Prefer setvbuf() to setlinebuf().
4045 2002-05-08 Paul D. Smith <psmith@gnu.org>
4047 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4048 (loadavg_LDADD): Ditto.
4050 2002-04-29 Paul D. Smith <psmith@gnu.org>
4052 * expand.c (recursively_expand_for_file): Rename
4053 recursively_expand() to recursively_expand_for_file() and provide
4054 an extra argument, struct file. If the argument is provided, set
4055 the variable scope to that of the file before expanding.
4056 * variable.h (recursively_expand): Make this a macro that invokes
4057 recursively_expand_for_file() with a NULL file pointer.
4058 * variable.c (target_environment): Call the renamed function and
4059 provide the current file context.
4060 Fixes Debian bug #144306.
4062 2002-04-28 Paul D. Smith <psmith@gnu.org>
4064 Allow $(call ...) user-defined variables to be self-referencing
4065 without throwing an error. Allows implementation of transitive
4066 closures, among other possibly useful things.
4067 Requested by: Philip Guenther <guenther@sendmail.com>
4069 * variable.h (struct variable): Add a new field: exp_count, and
4070 new macros to hold its size and maximum value.
4071 (warn_undefined): Make this a macro.
4072 * variable.c (define_variable_in_set): Initialize it.
4073 * expand.c (recursively_expand): If we detect recursive expansion
4074 of a variable, check the exp_count field. If it's greater than 0
4075 allow the recursion and decrement the count.
4076 (warn_undefined): Remove this (now a macro in variable.h).
4077 * function.c (func_call): Before we expand the user-defined
4078 function, modify its exp_count field to contain the maximum
4079 number of recursive calls we'll allow. After the call, reset it
4082 2002-04-21 Paul D. Smith <psmith@gnu.org>
4084 Modified to use latest autoconf (2.53), automake (1.6.1), and
4085 gettext (0.11.1). We're using gettext's new "external" support,
4086 to avoid including libintl source with GNU make.
4088 * README.cvs: New file. Explain how to build GNU make from CVS.
4090 * configure.in: Modify checking for the system glob library.
4091 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4092 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4093 etc. will manage it correctly). Set an automake conditional
4094 USE_LOCAL_GLOB to decide whether to compile the glob library.
4096 * getloadavg.c (main): Include make.h in the "TEST" program to
4099 * Makefile.am: Remove special rules for loadavg. Replace them
4100 with Automake capabilities for building extra programs.
4102 * signame.c: This file does nothing if the system provide
4103 strsignal(). If not, it implements strsignal(). If the system
4104 doesn't define sys_siglist, then we make our own; otherwise we use
4106 * signame.h: Removed.
4108 * main.c (main): No need to invoke signame_init(). Update copyright.
4110 * ABOUT-NLS: Removed.
4111 * gettext.c: Removed.
4112 * gettext.h: Get a simplified copy from the gettext package.
4114 * i18n/*.po: Moved to po/.
4117 * config/*: Created. Contains package configuration helper files.
4118 * config.guess, config.sub: Moved to config directory.
4120 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4121 Rework to use new-style autoconf features. Use the "external"
4122 mode for gettext. Make the build.sh config file conditional on
4123 whether build.sh.in exists, to avoid autoconf errors.
4124 * acinclude.m4: Removed almost all macros as being obsolete.
4125 Rewrote remaining macros to use AC_DEFINE.
4126 * acconfig.h: Removed.
4128 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4129 conditional to handle customs support. Remove special handling
4132 2002-04-20 Paul D. Smith <psmith@gnu.org>
4134 * function.c (func_call): Don't mark the argument variables $1,
4135 etc. as recursive. They've already been fully expanded so
4136 there's no need to do it again, and doing so strips escaped $'s.
4137 Reported by Sebastian Glita <glseba@yahoo.com>.
4139 * remake.c (notice_finished_file): Walk through double-colon
4140 entries via the prev field, not the next field!
4141 Reported by Greg McGary <greg@mcgary.org>.
4143 * main.c (main): If the user specifies -q and asks for a specific
4144 target which is a makefile, we got an assert. In that case it
4145 turns out we should continue normally instead.
4147 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4149 * i18n/he.po: Installed a new translation.
4151 2002-01-07 Paul D. Smith <psmith@gnu.org>
4153 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4155 2001-12-04 Paul D. Smith <psmith@gnu.org>
4157 * i18n/ja.po: Installed an updated translation.
4159 2001-09-06 Paul Eggert <eggert@twinsun.com>
4161 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4162 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4164 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4166 (main): Get rid of any avoidable limit on stack size.
4168 2001-09-04 Paul D. Smith <psmith@gnu.org>
4170 * i18n/da.po: Installed an updated translation.
4172 2001-08-03 Paul D. Smith <psmith@gnu.org>
4174 * i18n/fr.po: Installed an updated translation.
4175 Resolves Debian bug #106720.
4177 2001-06-13 Paul D. Smith <psmith@gnu.org>
4179 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4182 2001-06-11 Paul D. Smith <psmith@gnu.org>
4184 * i18n/ko.po: Installed a new translation.
4186 2001-05-06 Paul D. Smith <psmith@gnu.org>
4188 Modify the EINTR handling.
4190 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4191 the way in which we manage the file descriptor/signal handler race
4192 trap to be more efficient.
4194 2001-05-06 Paul Eggert <eggert@twinsun.com>
4196 Restart almost all system calls that are interrupted, instead
4197 of worrying about EINTR. The lone exception is the read() for
4200 * configure.in (HAVE_SA_RESTART): New macro.
4201 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4202 * main.c (main): Use SA_RESTART instead of the old,
4203 nonstandard SA_INTERRUPT.
4205 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4206 * main.c (bsd_signal): New function or macro,
4207 if the implementation doesn't supply it.
4208 (The bsd_signal function will be in POSIX 1003.1-200x.)
4209 (HANDLESIG): Remove.
4210 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4212 * make.h (EINTR_SET): Remove.
4213 (SA_RESTART): New macro.
4215 * arscan.c (ar_member_touch): Don't worry about EINTR.
4216 * function.c (func_shell): Likewise.
4217 * job.c (reap_children, free_child, new_job): Likewise.
4218 * main.c (main): Likewise.
4219 * remake.c (touch_file, name_mtime): Likewise.
4221 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4222 if fstat failed with errno!=EINTR, the error was ignored.
4224 * job.c (set_child_handler_action_flags): New function.
4225 (new_job): Use it to temporarily clear the SIGCHLD action flags
4226 while reading the token.
4228 2001-05-02 Paul D. Smith <psmith@gnu.org>
4230 * job.c (start_job_command): Don't add define/endef per-line flags
4231 to the top-level flags setting.
4233 2001-04-03 Paul D. Smith <psmith@gnu.org>
4235 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4236 bit on error, so check for odd return values, not non-0 return
4238 (VMS_get_member_info): Calculate the timezone differences correctly.
4239 Reported by John Fowler <jfowler@nyx.net>.
4242 2001-03-14 Paul D. Smith <psmith@gnu.org>
4244 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4245 value before invoking define_variable().
4246 Reported by John Fowler <jfowler@nyx.net>.
4248 2001-02-07 Paul D. Smith <psmith@gnu.org>
4250 * read.c (record_target_var): If we reset the variable due to a
4251 command-line variable setting overriding it, turn off the "append"
4254 2001-01-17 Paul D. Smith <psmith@gnu.org>
4256 * variable.c (lookup_variable) [VMS]: When getting values from the
4257 environment, allocate enough space for the _value_ plus escapes,
4258 not enough space for the name plus escapes :-/.
4259 Reported by John Fowler <jfowler@nyx.net>.
4261 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4262 warnings that make generates, so it doesn't look like an error.
4263 Reported by Karl Berry <karl@gnu.org>.
4266 Fix for PR/2020: Rework appended target-specific variables. I'm
4267 fairly confident this algorithm is finally correct.
4269 * expand.c (allocated_variable_append): Rewrite. Instead of
4270 expanding each appended variable then adding all the expanded
4271 strings together, we append all the unexpanded values going up
4272 through the variable set contexts, then expand the final result.
4273 This behaves just like non-target-specific appended variable
4274 values, while the old way didn't in various corner cases.
4275 (variable_append): New function: recursively append the unexpanded
4276 value of a variable, walking from the outermost variable scope to
4278 * variable.c (lookup_variable): Remove the code that looked up the
4279 variable set list if the found variable was "append". We don't
4281 (lookup_variable_in_set): Make this non-static so we can use it
4283 (try_variable_definition): Use lookup_variable_in_set() rather
4284 than faking out current_variable_set_list by hand (cleanup).
4285 * variable.h: Add a prototype for the now non-static
4286 lookup_variable_in_set().
4288 2000-11-17 Paul D. Smith <psmith@gnu.org>
4290 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4291 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4292 before throwing a fit.
4294 2000-11-17 Paul D. Smith <psmith@gnu.org>
4296 * read.c (readline): CRLF calculations had a hole, if you hit the
4297 buffer grow scenario just right. Reworked the algorithm to avoid
4298 the need for len or lastlen at all. Problem description with
4299 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4301 2000-10-24 Paul D. Smith <psmith@gnu.org>
4303 * gettext.c (SWAP): Declare this with the prototype, otherwise
4304 some systems don't work (non-32-bit? Reported for Cray T3E).
4305 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4307 2000-10-05 Paul D. Smith <psmith@gnu.org>
4309 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4310 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4312 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4314 2000-09-22 Paul D. Smith <psmith@gnu.org>
4316 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4317 parts of the real gettext.h here, and we expect to really include
4318 the real gettext.h later. If we keep this #define, it's ignored.
4320 2000-09-21 Paul D. Smith <psmith@gnu.org>
4322 * main.c (log_working_directory): Rework the text to use complete
4323 sentences, to make life simpler for the translators.
4325 2000-08-29 Paul D. Smith <psmith@gnu.org>
4327 * file.c (remove_intermediates): Print a debug message before we
4328 remove intermediate files, so the user (if she uses -d) knows
4331 2000-08-21 Paul D. Smith <psmith@gnu.org>
4333 * variable.c (try_variable_definition): Change how we handle
4334 target-specific append variable defns: instead of just setting the
4335 value, expand it as an append _but_ only within the current
4336 target's context. Otherwise we lose all but the last value if the
4337 variable is appended more than once within the current target
4338 context. Fixes PR/1831.
4340 2000-08-16 Paul D. Smith <psmith@gnu.org>
4342 * function.c (func_shell): Nul-terminate the buffer before
4343 printing an exec error message (just in case it's not!).
4344 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4346 2000-07-25 Paul D. Smith <psmith@gnu.org>
4348 * job.c (construct_command_argv_internal): Add "~" to the list of
4349 sh_chars[] which disallow optimizing out the shell call.
4351 2000-07-23 Paul Eggert <eggert@twinsun.com>
4353 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4354 supersedes --disable-nsec-timestamps.
4355 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4356 * README: Remove --disable-nsec-timestamps.
4358 * filedef.h (struct file.low_resolution_time): New member.
4359 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4360 * remake.c (update_file_1):
4361 Avoid spurious rebuilds due to low resolution time stamps,
4362 generalizing the earlier code that applied only to archive members.
4363 (f_mtime): Archive members always have low resolution time stamps.
4365 * configure.in: Remove --disable-nsec-timestamps, as this has
4366 been superseded by .LOW_RESOLUTION_TIME.
4368 2000-07-23 Paul Eggert <eggert@twinsun.com>
4370 * configure.in (enable_nsec_timestamps): Renamed from
4371 make_cv_nsec_timestamps, since enable/disable options
4372 shouldn't be cached.
4374 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4375 and Paul Eggert <eggert@twinsun.com>
4377 * file.c (file_timestamp_now):
4378 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4379 so that clock_gettime is not linked unless needed.
4381 * filedef.h (FILE_TIMESTAMP_HI_RES):
4382 Remove definition; "configure" now does this.
4384 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4385 to before high resolution file timestamp check,
4386 since that check now uses uintmax_t.
4387 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4388 high resolution file timestamps.
4389 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4390 so that we don't link in clock_gettime unnecessarily.
4392 2000-07-17 Paul D. Smith <psmith@gnu.org>
4394 * i18n/ja.po: New version of the translation file.
4396 2000-07-07 Paul D. Smith <psmith@gnu.org>
4398 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4399 the offset calculation.
4400 (name_mtime): Replace EINTR test with EINTR_SET macro.
4402 2000-07-07 Paul Eggert <eggert@twinsun.com>
4406 * remake.c (update_file_1):
4407 Avoid spurious rebuilds of archive members due to their
4408 timestamp resolution being only one second.
4409 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4410 the clock's resolution being lower than file timestamps'.
4411 When warning about future timestamps, report only the discrepancy,
4412 not the absolute value of the timestamp and the current time.
4414 * file.c (file_timestamp_now): New arg RESOLUTION.
4415 * filedef.h (file_timestamp_now): Likewise.
4416 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4418 2000-07-05 Paul D. Smith <psmith@gnu.org>
4420 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4421 to listp. Fixes PR/1793.
4423 2000-06-26 Paul Eggert <eggert@twinsun.com>
4425 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4427 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4429 * remake.c (f_mtime): Remove unused var memtime.
4431 2000-06-25 Martin Buchholz <martin@xemacs.org>
4433 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4434 Ran spell-check on make.texinfo.
4436 2000-06-23 Paul D. Smith <psmith@gnu.org>
4438 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4439 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4440 * make.h: Define these macros.
4442 * Version 3.79.1 released.
4444 * configure.in: Add a new option, --disable-nsec-timestamps, to
4445 avoid using sub-second timestamps on systems that support it. It
4446 can lead to problems, e.g. if your makefile relies on "cp -p".
4447 * README.template: Document the issue with "cp -p".
4449 * config.guess, config.sub: Updated.
