514 the LAST character in a word. If there is no word ending in ')'
515 then it's not an archive group. Fixes Savannah bug #28525.
517 2010-07-01 Paul Smith <psmith@gnu.org>
519 * main.c (main): Append optional features using separate calls.
520 Not as efficient but not all compilers allow conditionals inside
521 macro calls. Fixes Savannah bug #29244.
523 2010-01-10 Paul Smith <psmith@gnu.org>
525 * make.h (patheq): Rename strieq() to patheq() for clarity.

534 * job.c (construct_command_argv_internal) <sh_cmds_dos>
535 [WINDOWS32]: Add "echo." and a few more commands that are built
536 into cmd.exe. Fixes Savannah bug #28126.
538 * file.c (lookup_file) [HAVE_DOS_PATHS]: Treat '\\' like we do

571 2009-11-12 Boris Kolpackov <boris@codesynthesis.com>
573 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
574 which allows the caller to get the index of the matching directory.
576 * make.h (vpath_search): Update prototype.
578 * remake.c (library_search): Implement linker-compatible library
579 search. Use the new VPATH_SEARCH index functionality to keep track
580 of the directory index for each match. Select the match with the
581 lowest directory index.
583 * implicit.c (pattern_search): Pass NULL for the index arguments in
584 the VPATH_SEARCH call.
586 * doc/make.texi (Directory Search for Link Libraries): Describe the
589 * NEWS: Add a note about the new behavior.
591 2009-10-25 Paul Smith <psmith@gnu.org>
593 * AUTHORS, et.al.: Update copyright years.
595 * implicit.c (stemlen_compare): Fix qsort() compare bug that
596 caused implicit rules with equal stem lengths to be sorted
599 2009-10-24 Paul Smith <psmith@gnu.org>
601 * main.c (usage): Add --eval to the usage string.
602 (switches): Add the --eval switch.
603 (main): If --eval is given, add them to the simply-expanded variable
604 -*-eval-flags-*- (necessary to allow recursion to work properly).
605 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
607 * NEWS: Describe the new --eval command line argument.
608 * doc/make.texi (Options Summary): Document --eval.

611 * read.c (eval_buffer): Ditto.
614 * variable.h (define_variable_cname): New macro for constant
616 * default.c (set_default_suffixes): Use it.
617 * main.c (main): Ditto.

632 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
634 * read.c (do_undefine): Free the expanded variable name.
636 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
637 to normal upgrade logic from dep_hash_cmp to set_file_variables.
639 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
641 * dep.h (uniquize_deps): Remove.
643 * read.c (uniquize_deps): Merge into set_file_variables in
645 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
647 * commands.c (set_file_variables): Avoid modifying the dep
648 chain to achieve uniqueness. Fixes savannah bug 25780.
650 * implicit.c (pattern_search): Instead of re-setting all automatic
651 variables for each rule we try, just update $*.
653 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
655 * variable.h (undefine_variable_in_set): New function declaration.
656 (undefine_variable_global): New macro.
658 * variable.c (undefine_variable_in_set): New function implementation.
660 * read.c (vmodifiers): Add undefine_v modifier.

669 * NEWS: Add a note about the new directive.
671 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
673 * implicit.c (pattern_search): Initialize file variables only
674 if we need to parse a rule that requires the second expansion.
676 2009-10-03 Paul Smith <psmith@gnu.org>
678 * make.h: Include <alloca.h> even on systems where __GNUC__ is
679 defined. Not sure why it was done the other way.
680 Requested by David Boyce <dsb@boyski.com>.
682 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
684 * dep.h (dep): Add the DONTCARE bitfield.
686 * filedef.h (file):Add the NO_DIAG bitfield.
688 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
689 not struct file (a file can be a dependency of many targets,
690 some don't care, some do).
692 * remake.c (update_goal_chain): Propagate DONTCARE from struct
693 dep to struct file before updating the goal and restore it
695 (update_file): Don't prune the dependency graph if this target
696 has failed but the diagnostics hasn't been issued.
697 (complain): Scan the file's dependency graph to find the file
698 that caused the failure.
699 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
700 whether to print diagnostics.
702 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
704 2009-09-28 Paul Smith <psmith@gnu.org>
706 * doc/make.texi (Pattern Intro): Move the match algorithm
707 discussion into the "Pattern Match" node.

710 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
712 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
713 much of the command line on a single pass.
715 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
717 * varible.c (create_pattern_var): Insert variables into the
718 PATTERN_VARS list in the shortest patterns first order.
720 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
721 used to sort the rules.

735 2009-09-27 Paul Smith <psmith@gnu.org>
737 * doc/make.texi (Double-Colon): Mention that pattern rules with
738 double-colons have a different meaning. Savannah bug #27497.
740 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
742 * configh.dos.template: Remove unconditional definition of
743 SYS_SIGLIST_DECLARED.
744 Include <sys/version.h> because ports of GCC 4.3.0 and later no
745 longer include it, so macros like __DJGPP_MINOR__ are no longer
746 defined automatically.
748 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
749 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
750 instead of using the hardcoded ones.
751 (SUBDIRS): doc subdir added.
752 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
753 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
754 create html formated docs. texi2html may not be ported to DOS.
755 (make.info, make.dvi, make.ps, make.html): Make targets depend on
757 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
758 -I switch to look in ./ instead of ./doc.
759 (html): Target depend on html-recursive instead of make_1.html.
760 (make_1.html): Removed.
761 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
762 (all-recursive): Allow for more than one subdir in the build
764 (mostlyclean-recursive, clean-recursive, distclean-recursive)
765 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
766 (tags-recursive): Allow for more than one subdir in the build
768 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
769 targets. Enter into doc/ to produce the targets.
770 (all-am): $(INFO_DEPS) replaced by info.
772 2009-09-26 Paul Smith <psmith@gnu.org>
774 * read.c (record_files): Use free_ns() to free struct nameseq.
777 * rule.c (freerule): Use free_dep_chain().
779 * read.c (record_files): Free FILENAMES chain for implicit rules.
780 (eval): Static pattern targets go into the string cache.
782 * function.c (string_glob): Free NAME in the nameseq chain.
784 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
786 * implicit.c (pattern_search): Terminate early if we haven't
787 found any rules to try (performance improvement).
789 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
791 * implicit.c (pattern_search): Merge three parallel arrays,
792 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
793 of struct TRYRULE. In the old version the latter two arrays
794 had insufficient length.
796 2009-09-24 Paul Smith <psmith@gnu.org>
798 * implicit.c (pattern_search): Add back support for order-only
799 prerequisites for secondary expansion implicit rules, that were
800 accidentally dropped. If we find a "|", enable order-only mode
801 and set IGNORE_MTIME on all deps that are seen afterward.
802 (pattern_search): Fix memory leaks: for intermediate files where
803 we've already set the file variable and pattern variable sets, be
804 sure to either save or free them as appropriate.
806 2009-09-23 Paul Smith <psmith@gnu.org>
808 Rework the way secondary expansion is stored, for efficiency.
809 This changes secondary expansion so that ONLY WHEN we know we have
810 a possibility of needing secondary expansion, do we defer the
811 secondary expansion. This means more parsing the deps but we use
812 a lot less memory (due to the strcache). Also, this fixes
815 * read.c (eval): Don't parse the dep string here anymore.
816 (record_files): Take the dep argument as an unparsed string. If
817 secondary expansion is enabled AND the prereq string has a '$' in
818 it, then set NEED_2ND_EXPANSION and keep the entire string.
819 Otherwise, parse the dep string here to construct the dep list
820 with the names in the strcache.
822 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
823 duplicate the name string (others are in the strcache).
825 * implicit.c: Remove struct idep and free_idep_chain(): unused.
826 (struct patdeps): New structure to store prereq information.
827 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
828 which prerequisites need expansion, and expand only those.
830 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
831 and enter_prereqs(). split_prereqs() takes a fully-expanded string
832 and splits it into a DEP list, handling order-only prereqs.
833 (enter_prereqs): This function enters a list of DEPs into the file
834 database. If there's a stem defined, expand any pattern chars.
835 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
836 set. Use the above functions.
837 (snap_deps): Only perform second expansion on prereqs that need it,
838 as defined by the NEED_2ND_EXPANSION flag.
839 (print_prereqs): New function to print the prereqs
840 (print_file): Call print_prereqs() rather than print inline.
842 * hash.h (STRING_COMPARE): Take advantage of strcache() by
844 (STRING_N_COMPARE): Ditto.
845 (ISTRING_COMPARE): Ditto.
847 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
848 (parse_file_seq): Return void*
849 * read.c (parse_file_seq): Return void*.
850 (eval): Invoke macroized version of parse_file_seq()
851 * default.c (set_default_suffixes): Ditto.
852 * file.c (split_prereqs): Ditto.
853 * function.c (string_glob): Ditto.
854 * main.c (main): Ditto.
855 * rule.c (install_pattern_rule): Ditto.
857 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
859 2009-09-16 Paul Smith <psmith@gnu.org>
861 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
863 * dep.h: Create alloc_dep() / free_dep() macros.
865 * implicit.c (pattern_search): Take advantage of the new
866 parse_file_seq() to add the directory prefix to each prereq.
868 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
869 all. Avoid reversing chains. Support adding prefixes.
870 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
871 cached/non-cached results.
872 (eval): Remove multi_glob() & invoke new parse_file_seq().
873 * rule.c (install_pattern_rule): Ditto.
874 * main.c (main): Ditto.
875 * implicit.c (pattern_search): Ditto.
876 * function.c (string_glob): Ditto.
877 * file.c (parse_prereqs): Ditto.
878 * default.c (set_default_suffixes): Ditto.
880 * variable.c (parse_variable_definition): Don't run off the end of
881 the string if it ends in whitespace (found with valgrind).
883 * commands.c (set_file_variables): Keep space for all targets in
884 $? if -B is given (found with valgrind).
886 2009-09-15 Paul Smith <psmith@gnu.org>
888 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
889 (xcalloc): Add new function.
890 * make.h: New declarations.
892 * ar.c (ar_glob_match): New calling method for concat().
893 * main.c (main): Ditto.
894 (decode_env_switches): Ditto.
895 * read.c (eval_makefile): Ditto.
896 (tilde_expand): Ditto.
897 (parse_file_seq): Ditto.
898 * variable.c (target_environment): Ditto.
899 (sync_Path_environment): Ditto.
901 * ar.c (ar_glob_match): Use xcalloc().
902 * dir.c (file_impossible): Ditto.
903 * file.c (enter_file): Ditto.
904 * job.c (new_job): Ditto.
905 * read.c (parse_file_seq): Ditto.
906 * vmsfunctions.c (opendir): Ditto.
908 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
910 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
911 inside the loop that looks up environment for PATH.
913 2009-08-31 Eli Zaretskii <eliz@gnu.org>
915 * function.c (windows32_openpipe): Update envp after calling
916 sync_Path_environment.
918 2009-08-02 Paul Smith <psmith@gnu.org>
920 * remake.c (notice_finished_file): Ensure file->cmds is not null
921 before looping through them. Fixes Savannah bug #21824.
923 * doc/make.texi (Wildcard Examples): Clarify when objects is
924 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
925 (Include): Clarify the behavior of -include.
926 Fixes Savannah bug #18963.
928 2009-08-01 Paul Smith <psmith@gnu.org>
930 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
931 etc. come on the command line. Fixes Savannah bug #27093.
933 * expand.c (expand_argument): If the argument is large enough use
934 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
936 * variable.c (do_variable_definition): Avoid using alloca() to
937 hold values, which can be large. Fixes Savannah bug #23960.
939 * job.c (new_job): Use memmove() instead of strcpy() since both
940 pointers are in the same memory block. Fixes Savannah bug #27148.
941 Patch by Petr Machata.
943 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
945 * job.c (construct_command_argv_internal): Add "ulimit" and
946 "unset" to the sh_cmds for Unixy shells.
948 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
950 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
951 that set make_cv_sys_gnu_glob, so they are also correctly set
952 when the cache has been populated before.
954 2009-07-04 Eli Zaretskii <eliz@gnu.org>
956 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
957 exist, as realpath(3) does where it's supported.
959 2006-07-04 Eli Zaretskii <eliz@gnu.org>
961 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
962 (abspath): Support systems that define HAVE_DOS_PATHS (have
963 drive letters in their file names). Use IS_PATHSEP instead of a
964 literal '/' comparison. Fixes Savannah bug #26886.
966 2009-06-14 Paul Smith <psmith@gnu.org>
968 * remake.c (update_file_1): Remember the original file we marked
969 as updating, so we can clear that flag again. If we find a target
970 via vpath, FILE might change.
971 (check_dep): Ditto. Fixes Savannah bug #13529.
972 Patch by Reid Madsen <reid.madsen@tek.com>.
974 2009-06-13 Paul Smith <psmith@gnu.org>
976 * doc/make.texi (MAKEFILES Variable): Be explicit that files
977 included by MAKEFILES cannot give default goals.
978 * read.c (eval): If set_default is not set, pass the no-default-goal
979 value when we read included makefiles. Fixes Savannah bug #13401.
981 * ar.c (ar_name): Ensure that targets with empty parens aren't
982 considered archive member references: archive members must have a
983 non-empty "member" string. Fixes Savannah bug #18435.
985 * function.c (string_glob): Rely on multi_glob() to determine
986 whether files exist or not. Remove call to file_exists_p() which
987 is not always correct. Fixes Savannah bug #21231.
988 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
989 then only files that really exist will be returned.
990 * dep.h: Add new argument to multi_glob().
991 * rule.c (install_pattern_rule): Ditto.
992 * read.c (eval): Ditto.
993 * main.c (main): Ditto.
994 * implicit.c (pattern_search): Ditto.
995 * file.c (parse_prereqs): Ditto.
996 * default.c (set_default_suffixes): Ditto.
998 2009-06-09 Paul Smith <psmith@gnu.org>
1000 * commands.c (set_file_variables): If always_make_flag is set,
1001 always add the prereq to $?. Fixes Savannah bug #17825.
1003 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1004 to rebuild the deps of all the also_make targets for that file.
1005 Fixes Savannah bug #19108.
1007 * implicit.c (pattern_search): Undo test for is_target, added by
1008 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1009 Rule Search Algorithm". Fixes Savannah bug #17752.
1011 * main.c (clean_jobserver): Clear the jobserver_fds options and
1012 set job_slots to the default when we clean up.
1013 (define_makeflags): Return the new MAKEFLAGS value.
1014 (main): Reset MAKEFLAGS in the environment when we re-exec.
1015 Fixes Savannah bug #18124.
1017 2009-06-08 Paul Smith <psmith@gnu.org>
1019 * read.c (eval): Collapse continuations post-semicolon on target-
1020 specific variables. Fixes Savannah bug #17521.
1022 2009-06-07 Paul Smith <psmith@gnu.org>
1024 * job.c (reap_children): For older systems without waitpid() (are
1025 there any of these left?) run wait(2) inside EINTRLOOP to handle
1026 EINTR errors. Fixes Savannah bug #16401.
1028 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1030 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1032 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1033 not the end, to catch second expansion $(eval ...) defining new
1034 target/prereq relationships during snap_deps.
1035 Fixes Savannah bug #24622.
1037 * read.c (record_files): The second-expansion "f->updating" hack
1038 was not completely correct: if assumed that the target with
1039 commands always had prerequisites; if one didn't then the ordering
1040 was messed up. Fixed for now to use f->updating to decide whether
1041 to preserve the last element in the deps list... but this whole
1042 area of constructing and reversing the deps list is too confusing
1043 and needs to be reworked. Fixes Savannah bug #21198.
1045 2009-06-06 Paul Smith <psmith@gnu.org>
1047 * hash.c (hash_insert): Remove useless test for NULL.
1048 Fixes Savannah bug #21823.
1050 * make.h: Move SET_STACK_SIZE determination to make.h.
1051 * main.c (main): New global variable, STACK_LIMIT, holds the
1052 original stack limit when make was started.
1053 * job.c (start_job_command): Reset the stack limit, if we changed it.
1054 Fixes Savannah bug #22010.
1056 * remake.c (check_dep): Only set the target's state to not-started
1057 if it's not already running. Found this while testing -j10 builds
1058 of glibc: various targets were being rebuilt multiple times.
1059 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1062 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1063 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1066 2009-06-04 Paul Smith <psmith@gnu.org>
1068 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1070 * maintMakefile: Modify access of config and gnulib Savannah
1071 modules to use GIT instead of CVS.
1073 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1074 Fixes Savannah bug #24655.
1076 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1077 this can happen during some invocations of $(eval ...) for example.
1078 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1080 2009-06-02 Paul Smith <psmith@gnu.org>
1082 * configure.in: Check for fileno()
1083 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1084 for the makefile file so invocations of $(shell ...) don't inherit it.
1085 Fixes Savannah bug #24277.
1087 2009-06-01 Paul Smith <psmith@gnu.org>
1089 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1090 expansion was handled incorrectly. Rework the default goal
1091 handling to save the variable only. Remove default_goal_file and
1093 * read.c (eval): Check default_goal_var, not default_goal_name.
1094 * read.c (record_target_var): Don't check default_goal_file here.
1096 2009-05-31 Paul Smith <psmith@gnu.org>
1098 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1099 it, and if the multi_glob() returns nothing (say it expanded to
1100 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1102 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1103 $(and ..) to the reference. Fixes Savannah bug #25694.
1105 * make.1: Be clear that some recipes will be executed even with -n.
1106 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1108 * doc/make.texi (Override Directive): Make more clear how
1109 overrides and appends interact.
1110 Elucidates part of Savannah bug #26207.
1112 * read.c (record_target_var): Don't reset the origin on
1113 target-specific variables; try_variable_definition() will handle
1114 this correctly. Fixes Savannah bug #26207.
1116 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1117 Fixes Savannah bug #25712.
1119 * implicit.c (pattern_search): Keep a pointer to the beginning of
1120 the filename and save that instead of the constructed pointer.
1121 Fixes Savannah bug #26593.
1122 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1124 2009-05-30 Paul Smith <psmith@gnu.org>
1126 * doc/make.texi (Multi-Line): Add a description of the new abilities
1127 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1128 "command sequence" vs. "recipe" syntax.
1129 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1130 after a define, to create variables with those flavors.
1132 2009-05-25 Paul Smith <psmith@gnu.org>
1134 Reworked the parser for variable assignments to allow multiple
1135 modifiers, and in any order. Also allows variable and
1136 prerequisites to be modifier names ('export', 'private', etc.)
1138 * NEWS: Add notes about user-visible changes.
1140 * read.c (struct vmodifiers): Remember what modifiers were seen.
1141 (parse_var_assignment): New function to parse variable assignments.
1142 (eval): Call the new function. Handle variable assignments earlier.
1144 * variable.c (parse_variable_definition): Only parse; don't create var.
1145 (assign_variable_definition): Call parse, then create the var.
1147 2009-05-24 Paul Smith <psmith@gnu.org>
1149 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1150 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1152 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1154 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1155 Fixes Savannah bug #25412.
1157 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1158 prototype for xmalloc.
1159 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1160 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1161 Loop over an array of extensions, instead of duplicating the same
1162 code inline. Use SearchPath followed by CreateFile, instead of
1163 the obsolete OpenFile. Fixes Savannah bug #17277.
1164 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1165 to `find_file'. Fixes Savannah bug #25662.
1167 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1169 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1170 Fixes Savannah bug #20495.

1174 * doc/make.texi (Instead of Execution): Document interaction of
1175 -t with phony targets.
1177 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1179 Introduce a new keyword "private" which applies to target-specific
1180 variables and prevents their values from being inherited.
1182 * variable.h (struct variable): Add private_var flag to each variable.
1183 Add a flag to specify which list entry switches to the parent target.
1184 * variable.c (define_variable_in_set): Initialize private_var flag.

1197 * make.h: Rename savestring to xstrndup.
1198 * commands.c (chop_commands): Ditto.
1199 * function.c (func_foreach): Ditto.
1200 * read.c (eval, record_files): Ditto.

1203 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1205 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1208 * w32/subproc/build.bat (GCCBuild): Likewise.
1210 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1212 * job.c (construct_command_argv_internal): Avoid extra backslash
1213 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1216 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1218 * README.W32.template: Remove obsolete text about non-support for
1219 -jN without Unixy shell. Remove obsolete text about not supplying
1220 Visual Studio project files (we do supply them). Modify text to
1221 prefer GCC builds to MSC builds.
1223 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1225 * doc/make.texi (Empty Targets): Fix typo.

1240 `value' field is NULL.
1242 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1244 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1246 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1247 (TEXINFOS): Value changed to `doc/make.texi'.
1248 (.SUFFIXES): Use .texi instead of .texinfo.
1249 (make.info, make.dvi): Depend on doc/make.texi.
1250 (.texi.info): New target, instead of ".texinfo.info". Change -I
1251 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1252 (.texi): New target, instead of ".texinfo". Change -I switch to
1253 $(MAKEINFO) to look in doc/. Use --no-split.
1254 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1255 switch to $(MAKEINFO) to look in doc/.
1256 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1257 "*.i[0-9][0-9]" (due to --no-split above).
1258 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1259 (html, make_1.html): New targets.
1260 (.PHONY): Add "html".
1261 (.SUFFIXES): Add .html.
1263 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1265 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1266 HAVE_DECL_SYS_SIGLIST.
1268 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1269 build does not use child_execute_job.
1271 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1272 export the SHELL environment variable to the child.
1274 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1276 * config.h.W32: Include sys/types.h.
1277 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1279 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1280 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1283 2007-11-04 Paul Smith <psmith@gnu.org>
1285 * doc/make.texi: Convert references to "commands", "command
1286 lines", and "command script" to "recipe".
1288 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1291 2007-10-27 Bruno Haible <bruno@clisp.org>
1293 * remake.c (f_mtime): Print time difference values between 100 and
1294 ULONG_MAX in fixed-point notation rather than in exponention notation.
1296 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1298 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1299 a more complex value than a simple shell: if it's not a default
1300 shell now then expand it and see if is a default shell then.
1302 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1304 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1305 pathnames, with const strings.
1306 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1307 from the template (used for building from CVS, not a dist).
1309 2007-10-10 Paul Smith <psmith@gnu.org>
1311 * make.h: Add a prototype for w32_kill() (change suggested by
1312 Yongwei Wu <wuyongwei@gmail.com>).
1314 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1316 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1317 directories in Path.
1319 2007-09-12 Paul Smith <psmith@gnu.org>
1321 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1322 Provided by Diego Biurrun <diego@biurrun.de>
1323 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1324 Provided by Diego Biurrun <diego@biurrun.de>
1326 2007-09-11 Paul Smith <psmith@gnu.org>
1328 * doc/make.texi (Special Variables): Moved this into the "How to
1329 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1330 (MAKEFILE_LIST) No longer a section; this was added into the
1331 "Special Variables" section.
1332 (Rule Introduction): Reference .RECIPEPREFIX.
1333 (Simple Makefile): Ditto.
1334 (Rule Syntax): Ditto.
1335 (Command Syntax): Ditto.
1336 (Error Messages): Ditto.
1338 2007-09-10 Paul Smith <psmith@gnu.org>
1340 * commands.c (print_commands): Don't print an extra line in the
1341 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1343 * read.c (construct_include_path): Add the full string to the cache; we
1344 were chopping the last char.
1346 * NEWS: Announce the .RECIPEPREFIX special variable.
1347 * variable.c (lookup_special_var): Rename from handle_special_var().
1348 (lookup_variable): Call the new name.
1349 (set_special_var): New function: handle setting of special variables.
1350 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1351 (do_variable_definition): Call it.
1352 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1353 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1354 * main.c (main): Create the .RECIPEPREFIX special variable.
1355 * read.c (eval): Remove the cmd_prefix characters from the command
1356 scripts here, so they're not stored in the commands array at all,
1357 rather than waiting and stripping them out during command construction.
1358 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1360 2007-08-15 Paul Smith <psmith@gnu.org>
1362 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1363 file has had the section info removed, so add some to make.texi
1364 before we include it.
1366 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1368 * remake.c (check_dep): Reset the target state for intermediate
1369 files. They might have been considered before but not updated
1370 then (order-only for example) but they will be this time.
1371 Fixes Savannah bug #'s 3330 and 15919.
1373 2007-07-21 Eli Zaretskii <eliz@gnu.org>

1376 * function.c (func_shell): Call construct_command_argv with zero
1378 * job.c (construct_command_argv_internal): New argument FLAGS; all
1380 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1382 * job.h (construct_command_argv_internal): Update prototype.
1384 2007-07-13 Paul Smith <psmith@gnu.org>
1386 * file.c (expand_deps): Use variable_buffer as the start of the
1387 buffer, not the original pointer (in case it was reallocated).
1388 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1389 Fixes Savannah bug #20452.
1391 2007-07-04 Paul Smith <psmith@gnu.org>
1393 * (ALL FILES): Update to GPLv3.
1394 * (ALL FILES): Update copyright for 2007.

1398 2007-06-29 Thiemo Seufer <ths@mips.com>
1400 * maintMakefile: Update Translation Project location.
1402 2007-06-13 Paul Smith <psmith@gnu.org>
1404 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1405 "Expansion of a deferred"
1406 Fixes Savannah bug #20018.
1408 * expand.c (variable_expand_for_file): Preserve the value of
1409 reading_file rather than setting it to 0 at the end.
1410 Fixes Savannah bug #20033.
1412 2007-05-11 Paul Smith <psmith@gnu.org>
1414 * job.c (new_job): Add debug info to specify where make found the
1415 command script it is running to build a target.
1416 Fixes Savannah bug #18617.
1418 * default.c (default_suffixes,default_suffix_rules,default_variables):
1419 Add support for Objective C. Fixes Savannah bug #16389.
1420 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1422 * function.c (func_lastword): Initialize p.
1424 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1425 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1426 Dave Korn <dave.korn@artimi.com>
1428 2007-05-08 Paul Smith <psmith@gnu.org>
1430 Fix Savannah bug #19656:
1432 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1434 * make.h: Change all case-insensitive string compares to use
1435 strcasecmp() (from POSIX). If we don't have that but do have one
1436 of the others, define strcasecmp to be one of those instead. If
1437 we don't have any, declare a prototype for our own version.
1439 * misc.c (strcasecmp): Use this if we can't find any native
1440 case-insensitive string comparison function.
1441 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1442 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1444 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1445 strcasecmp() instead of stricmp().
1446 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1447 instead of strcmpi().
1448 * acinclude.m4: Remove the strcasecmp() check from here.
1450 2007-03-21 Paul Smith <psmith@gnu.org>
1452 * configure.in: Don't turn on case-insensitive file system support
1453 if --disable-... is given. Fixes Savannah bug #19348.
1455 2007-03-19 Paul Smith <psmith@gnu.org>
1457 * ALL: Use the strcache for all file name strings, or other
1458 strings which we will never free. The goal is to save memory by
1459 avoiding duplicate copies of strings. However, at the moment this
1460 doesn't save much memory in most situations: due to secondary
1461 expansion we actually save prerequisite lists twice (once before
1462 the secondary expansion, and then again after it's been parsed
1463 into individual file names in the dep list). We will resolve this
1464 in a future change, by doing the parsing up-front for targets
1465 where secondary expansion is not set.
1467 Moving things into the strcache also allows us to use const
1468 pointers in many more places.
1470 2007-01-03 Paul Smith <psmith@gnu.org>
1472 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1473 the function, not just the first. Fixes Savannah bug #18680.
1475 2006-11-18 Paul Smith <psmith@gnu.org>
1477 * strcache.c (strcache_add_len): Don't allocate a new buffer
1478 unless the string is not already nil-terminated. Technically this
1479 is a violation of the standard, since we may be passed an array
1480 that is not long enough to test one past. However, in make this
1481 is never true since we only use nil-terminated strings or
1482 sub-strings thereof.
1484 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1486 * main.c: New global cmd_prefix, defaults to '\t'.
1487 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1490 * dir.c: Constified.
1491 (dir_contents_file_exists_p): Check for an error return from
1492 readdir(), just in case.
1494 * commands.c: Constified.
1495 * default.c: Constified.
1496 * expand.c: Constified.
1497 * function.c: Partial constification.
1498 * variable.c: Partial constification.
1499 * vmsify.c: Constification. Hard to test this but I hope I didn't
1501 * vpath.c: Partial constification.
1502 * w32/pathstuff.c: Partial constification.
1504 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1506 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1507 backslashes and drive letters as absolute.
1509 2006-10-22 Paul Smith <psmith@gnu.org>
1511 * main.c (struct command_switch): Use const and void*.
1513 2006-10-21 Paul Smith <psmith@gnu.org>
1516 * arscan.c: Constified.
1518 2006-09-30 Paul Smith <psmith@gnu.org>
1520 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1521 point to lastword since the example was updated.
1522 Fixes Savannah bug #16304.
1523 (Secondary Expansion): Correct example description.
1524 Fixes Savannah bug #16468.
1525 (Makefile Contents): Clarify that comments cannot appear within
1526 variable references or function calls.
1527 Fixes Savannah bug #16577.
1528 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1529 Fixes Savannah bug #17701.
1530 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1531 (Prerequisite Types): Added an example of using order-only
1532 prerequisites. Fixes Savannah bug #17880.
1533 (Rule Syntax): "lise" -> "list"
1534 (Multiple Rules): ... -> @dots{}
1535 (Splitting Lines): ditto.
1537 * remake.c (update_file_1): Prereqs that don't exist should be
1538 considered changed, for the purposes of $?.
1539 Fixes Savannah bug #16051.
1541 * make.1: Remove extraneous "+".
1542 Fixes Savannah bug #16652.
1544 2006-09-06 Paul D. Smith <psmith@gnu.org>
1546 * configure.in: Include sys/types.h when checking for sys/wait.h.
1548 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1550 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1553 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1554 Normally, it is defined in config.h.
1556 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1559 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1560 sh_chars_sh for Windows platforms that emulate Unix.
1562 2006-05-07 Paul D. Smith <psmith@gnu.org>
1564 * README.OS2.template: Updates provided by Andreas Buening
1565 <andreas.buening@nexgo.de>.
1567 2006-04-30 Paul D. Smith <psmith@gnu.org>
1569 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1570 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1572 2006-04-26 Paul D. Smith <psmith@gnu.org>
1574 * README.cvs: Add a reminder to notify the GNU translation robot.
1576 * doc/make.texi: Change @direcategory (requested by Karl Berry).
1578 2006-04-20 Paul D. Smith <psmith@gnu.org>

1588 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1589 inner-scope variables don't mask outer-scope variables.

1594 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1595 values from memory allocation functions: they return void* and so
1596 don't need to be cast. Also remove (char *) casts of arguments to

1628 2006-04-01 Paul D. Smith <psmith@gnu.org>
1630 Version 3.81 released.
1632 * NEWS: Updated for 3.81.
1634 * README.cvs: Mention that vpath builds are not supported out of
1635 CVS. Fixes Savannah bug #16236.
1636 Remove update of make.texi from the list of things to do; we use
1639 2006-03-26 Paul D. Smith <psmith@gnu.org>
1641 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1642 support from automake, as described in the Texinfo manual.
1644 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1646 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1647 with lastslash, since the latter points to filename, not to
1649 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1650 Declare and define sh_chars_sh[].
1652 2006-03-23 Paul D. Smith <psmith@gnu.org>
1654 * configure.in: Look for build.sh.in in $srcdir so it will be
1655 built for remote configurations as well.
1657 * Makefile.am: Make sure to clean up build.sh during distclean.
1658 Fixes Savannah bug #16166.
1660 * misc.c (log_access): Takes a const char *.
1661 * function.c (fold_newlines): Takes an unsigned int *.
1662 Both fixes for Savannah bug #16170.
1664 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1666 * implicit.c (pattern_search): Call set_file_variables only
1667 if we have prerequisites that need second expansion. Fixes
1668 Savannah bug #16140.
1670 2006-03-19 Paul D. Smith <psmith@gnu.org>
1672 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1673 memory on hosts that don't support it directly.

1683 Reported by Craig Fithian <craig.fithian@citigroup.com>
1685 2006-03-17 Paul D. Smith <psmith@gnu.org>
1687 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1688 allow multiple concurrent runs.
1689 Patch from Joseph Myers <joseph@codesourcery.com>
1691 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1693 * dep.h (struct dep): Add the stem field.
1694 * misc.c (alloc_dep, free_dep): New functions.
1695 (copy_dep_chain): Copy stem.
1696 (free_dep_chain): Use free_dep.
1697 * read.c (record_files): Store stem in the dependency line.
1698 * file.c (expand_deps): Use stem stored in the dependency line. Use
1699 free_dep_chain instead of free_ns_chain.
1700 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1701 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1702 * main.c (main, handle_non_switch_argument): Ditto.
1703 * remake.c (check_dep): Ditto.

1706 2006-03-14 Paul D. Smith <psmith@gnu.org>
1708 * expand.c (variable_append): Instead of appending everything then
1709 expanding the result, we expand (or not, if it's simple) each part
1711 (allocated_variable_append): Don't expand the final result.
1712 Fixes Savannah bug #15913.
1714 2006-03-09 Paul Smith <psmith@gnu.org>
1716 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1717 listed non-existent files as changed. Turns out there's a bug in
1718 the Linux kernel builds which means that this change causes
1719 everything to rebuild every time. We will re-introduce this fix
1720 in the next release, to give them time to fix their build system.
1721 Fixes Savannah bug #16002.
1722 Introduces Savannah bug #16051.
1724 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1731 locator function find_and_set_default_shell if SHELL came from the
1734 2006-02-20 Paul D. Smith <psmith@gnu.org>
1736 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1737 to be null; don't core in that case.
1739 2006-02-19 Paul D. Smith <psmith@gnu.org>
1741 * commands.c (set_file_variables): Realloc, not malloc, the static
1742 string values to avoid memory leaks.
1744 * expand.c (recursively_expand_for_file): Only set reading_file to
1745 an initialized value.
1747 * implicit.c (pattern_search): We need to make a copy of the stem
1748 if we get it from an intermediate dep, since those get freed.
1750 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1752 (enter_file) [VMS]: Ditto.
1753 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1757 * job.c (construct_command_argv_internal): Fix last change.
1759 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1760 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1761 the calls to _beginthreadex.
1763 * expand.c (recursively_expand_for_file): Initialize `save' to
1764 prevent compiler warnings.
1766 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1768 * job.c (construct_command_argv_internal): Don't create a temporary
1769 script/batch file if we are under -n. Call _setmode to switch the
1770 script file stream to text mode.
1772 2006-02-17 Paul D. Smith <psmith@gnu.org>
1774 * variable.c (merge_variable_set_lists): Don't try to merge the
1775 global_setlist. Not only is this useless, but it can lead to
1776 circularities in the linked list, if global_setlist->next in one
1777 list gets set to point to another list which also ends in
1779 Fixes Savannah bug #15757.
1781 2006-02-15 Paul D. Smith <psmith@gnu.org>
1783 Fix for Savannah bug #106.
1785 * expand.c (expanding_var): Keep track of which variable we're
1786 expanding. If no variable is being expanded, it's the same as
1788 * make.h (expanding_var): Declare it.
1789 * expand.c (recursively_expand_for_file): Set expanding_var to the
1790 current variable we're expanding, unless there's no file info in
1791 it (could happen if it comes from the command line or a default
1792 variable). Restore it before we exit.
1793 * expand.c (variable_expand_string): Use the expanding_var file
1794 info instead of the reading_file info.
1795 * function.c (check_numeric): Ditto.
1797 (func_wordlist): Ditto.
1798 (func_error): Ditto.
1799 (expand_builtin_function): Ditto.
1800 (handle_function): Ditto.
1802 2006-02-14 Paul D. Smith <psmith@gnu.org>
1804 * read.c (eval): Even if the included filenames expands to the
1805 empty string we still need to free the allocated buffer.
1807 * implicit.c (pattern_search): If we allocated a variable set for
1808 an impossible file, free it.
1809 * variable.c (free_variable_set): New function.
1810 * variable.h: Declare it.
1812 * read.c (read_all_makefiles): Makefile names are kept in the
1813 strcache, so there's never any need to alloc/free them.
1816 * main.c (main): Add "archives" to the .FEATURES variable if
1817 archive support is enabled.
1818 * doc/make.texi (Special Variables): Document it.
1820 2006-02-13 Paul D. Smith <psmith@gnu.org>
1822 * implicit.c (pattern_search): Add checking for DOS pathnames to
1823 the pattern rule target LASTSLASH manipulation.

1828 * (ALL FILES): Updated copyright and license notices.
1830 2006-02-10 Paul D. Smith <psmith@gnu.org>
1832 A new internal capability: the string cache is a read-only cache
1833 of strings, with a hash table interface for fast lookup. Nothing
1834 in the cache will ever be freed, so there's no need for reference
1835 counting, etc. This is the beginning of a full solution for
1836 Savannah bug #15182, but for now we only store makefile names here.
1838 * strcache.c: New file. Implement a read-only string cache.
1839 * make.h: Add prototypes for new functions.
1840 * main.c (initialize_global_hash_tables): Initialize the string cache.
1841 (print_data_base): Print string cache stats.
1842 * read.c (eval_makefile): Use the string cache to store makefile
1843 names. Rewrite the string allocation to be sure we free everything.
1845 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1847 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1848 directory time stamp didn't change, except on FAT filesystems.
1849 Suggested by J. David Bryan <jdbryan@acm.org>.
1851 2006-02-09 Paul D. Smith <psmith@gnu.org>
1853 * function.c (func_or): Implement a short-circuiting OR function.
1854 (func_and): Implement a short-circuiting AND function.
1855 (function_table_init): Update the table with the new functions.
1856 * doc/make.texi (Conditional Functions): Changed the "if" section
1857 to one on general conditional functions. Added documentation for
1858 $(and ...) and $(or ...) functions.
1859 * NEWS: Note new $(and ...) and $(or ...) functions.

1866 one in struct file. Fixes Savannah bug #15641.
1868 2006-02-06 Paul D. Smith <psmith@gnu.org>
1870 * vpath.c (selective_vpath_search): If the file we find has a
1871 timestamp from -o or -W, use that instead of the real time.
1872 * remake.c (f_mtime): If the mtime is a special token from -o or
1873 -W, don't overwrite it with the real mtime.
1874 Fixes Savannah bug #15341.
1876 Updates from Markus Mauhart <qwe123@chello.at>:
1878 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1879 (process_signal, process_last_err, process_exit_code): Manage
1880 invalid handle values.
1881 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1882 manage invalid handles; remove them.

1884 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1891 Fixes Savannah bug #15533.
1892 * filedef.h (struct file): Add a new LAST pointer.
1894 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1895 the comparison. For 64-bits systems the result of the subtraction
1896 might not fit into an int. Use comparison instead.
1897 Fixes Savannah bug #15534.
1899 * doc/make.texi: Update the chapter on writing commands to reflect
1900 the changes made in 3.81 for backslash/newline and SHELL handling.

1904 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1905 variable st is not used when it's not initialized.

1920 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1922 * remake.c (update_goal_chain): Set g->changed instead of
1923 incrementing it, as it is only 8-bit wide, and could overflow if
1924 many commands got started in update_file.
1926 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1928 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1946 the shell is not sh.exe.
1948 * job.c (create_batch_file): Renamed from create_batch_filename;
1949 all callers changed. Don't close the temporary file; return its
1950 file descriptor instead. New arg FD allows to return the file
1952 (construct_command_argv_internal): Use _fdopen instead of fopen to
1953 open the batch file.
1955 2006-01-04 Paul D. Smith <psmith@gnu.org>

1985 handling of backslash-newline sequences. Mention the differences
1986 on MS-DOS and MS-Windows.
1988 * NEWS: More details about building the MinGW port and a pointer
1989 to README.W32. Fix the section name that describes the new
1990 backward-incompatible processing of backslash-newline sequences.
1991 The special processing of SHELL set to "cmd" is only relevant to
1992 MS-Windows, not MS-DOS.
1994 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1996 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1997 to DWORD, to avoid compiler warnings.

2019 * make.1: Fix some display errors and document all existing options.
2020 Patch by Mike Frysinger <vapier@gentoo.org>.
2022 2005-12-11 Paul D. Smith <psmith@gnu.org>
2024 * implicit.c (pattern_search): If 2nd expansion is not set for
2025 this implicit rule, replace the pattern with the stem directly,
2026 and don't re-expand the variable list. Along with the other
2027 .SECONDEXPANSION changes below, fixes bug #13781.
2029 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2031 * implicit.c (pattern_search): Mark other files that this rule

2093 * main.c (main): Set CURDIR to be a file variable instead of a
2094 default, so that values of CURDIR inherited from the environment
2095 won't override the make value.
2097 2005-09-26 Paul D. Smith <psmith@gnu.org>
2099 * job.c (construct_command_argv_internal): If the line is empty
2100 remember to free the temporary argv strings.
2103 2005-09-16 Paul D. Smith <psmith@gnu.org>
2105 * job.c (start_job_command): The noerror flag is a boolean (single
2106 bit); set it appropriately.
2107 Reported by Mark Eichin <eichin@metacarta.com>
2109 2005-08-29 Paul D. Smith <psmith@gnu.org>
2111 * function.c (func_error): On Windows, output from $(info ...)
2112 seems to come in the wrong order. Try to force it with fflush().
2114 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2116 * read.c (record_files): Move code that sets stem for static
2117 pattern rules out of the if (!two_colon) condition so it is
2118 also executed for two-colon rules. Fixes Savannah bug #13881.
2120 2005-08-08 Paul D. Smith <psmith@gnu.org>
2122 * make.h: Don't test that __STDC__ is non-0. Some compilers
2123 (Windows for example) set it to 0 to denote "ISO C + extensions".
2126 2005-08-07 Paul D. Smith <psmith@gnu.org>
2128 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2129 conditional (slightly different version of a fix from Eli).
2131 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2132 If make is running in parallel without -k and two jobs die in a
2133 row, but not too close to each other, then make will quit without
2134 waiting for the rest of the jobs to die.
2136 * main.c (die): Don't reset err before calling reap_children() the
2137 second time: we still want it to be in the error condition.
2138 * job.c (reap_children): Use a static variable, rather than err,
2139 to control whether or not the error message should be printed.
2141 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2143 * w32/subproc/sub_proc.c: Include signal.h.
2144 (process_pipe_io, process_file_io): Pass a pointer to a local
2145 DWORD variable to GetExitCodeProcess. If the exit code is
2146 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2148 * job.c [WINDOWS32]: Include windows.h.
2149 (main_thread) [WINDOWS32]: New global variable.
2150 (reap_children) [WINDOWS32]: Get the handle for the main thread
2151 and store it in main_thread.
2153 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2154 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2155 doing anything else. When we are done, close the main thread
2156 handle and exit with status 130.
2158 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2160 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2163 * main.c (find_and_set_default_shell): If found a DOSish shell,
2164 set sh_found and the value of default_shell, and report the
2165 findings in debug mode.
2167 * job.c (construct_command_argv_internal): Check unixy_shell, not
2168 no_default_sh_exe, to decide whether to use Unixy or DOSish
2171 * README.W32: Update with info about the MinGW build.
2173 * build_w32.bat: Support MinGW.
2175 * w32/subproc/build.bat: Likewise.
2177 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2178 printing DWORD args.
2180 * function.c (windows32_openpipe): Fix format strings for printing
2183 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2185 (start_job_command): Fix format string for printing the result of
2187 (start_job_command) [WINDOWS32]: Do not define.
2188 (exec_command): Fix format string for printing HANDLE args.
2190 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2191 to avoid compiler warnings.
2192 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2193 (Note: some of these fixes were submitted independently by J. Grant)
2195 2005-07-30 J. Grant <jg@jguk.org>
2197 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2198 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2199 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2201 2005-07-15 Paul Smith <psmith@gnu.org>
2203 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2204 we don't have a POSIX shell, then revert to the old
2205 backslash-newline behavior (where they are stripped).
2208 2005-07-08 Paul D. Smith <psmith@gnu.org>
2210 * config.h.W32.template: Reorder to match the standard config.h,
2211 for easier comparisons.
2212 From J. Grant <jg@jguk.org>
2214 * maintMakefile: Remove .dep_segment before overwriting it, in
2215 case it's not writable or noclobber is set.
2216 * expand.c (variable_expand_string): Cast result of pointer
2217 arithmetic to avoid a warning.
2218 * main.c (switches): Add full-fledged final initializer.
2220 2005-07-06 Paul D. Smith <psmith@gnu.org>
2222 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2223 * signame.c (strsignal): If we found _sys_siglist[] or
2224 __sys_siglist[] use those instead of sys_siglist[].
2225 From Albert Chin <china@thewrittenword.com>
2227 2005-07-04 Paul D. Smith <psmith@gnu.org>
2229 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2230 globfree(); set up to use the GNU versions.
2231 From Martin Zinser <zinser@zinser.no-ip.info>
2233 2005-07-03 Paul D. Smith <psmith@gnu.org>
2235 From J. Grant <jg@jguk.org>:
2237 * README.W32.template: Update the Windows and tested MSVC versions.
2238 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2239 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2240 * build_w32.bat: Ditto.
2241 * w32/subproc/build.bat: Ditto.
2243 2005-06-28 Paul D. Smith <psmith@gnu.org>
2245 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2246 declaration was checked but not present.
2248 2005-06-27 Paul D. Smith <psmith@gnu.org>
2250 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2251 to unsigned long. Fixes Savannah bug #13550.
2253 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2254 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2255 Fixes Savannah bug #13551.
2257 2005-06-26 Paul D. Smith <psmith@gnu.org>
2259 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2260 it if ANSI_STRING is not set.
2262 2005-06-25 Paul D. Smith <psmith@gnu.org>
2264 * read.c (eval): If no filenames are passed to any of the
2265 "include" variants, don't print an error.
2266 * doc/make.texi (Include): Document this.
2267 Fixes Savannah bug #1761.
2269 * job.c (construct_command_argv_internal): Sanitize handling of
2270 backslash/newline pairs according to POSIX: that is, keep the
2271 backslash-newline in the command script, but remove a following
2272 TAB character, if present. In the fast path, make sure that the
2273 behavior matches what the shell would do both inside and outside
2274 of quotes. In the slow path, quote the backslash and put a
2275 literal newline in the string.
2276 Fixes Savannah bug #1332.
2277 * doc/make.texi (Execution): Document the new behavior and give
2279 * NEWS: Make a note of the new behavior.
2281 * make.h [WINDOWS32]: #include <direct.h>.
2282 Fixes Savannah bug #13478.
2284 * remake.c (name_mtime): If the stat() of a file fails and the -L
2285 option was given and the file is a symlink, take the best mtime of
2286 the symlink we can get as the mtime of the file and don't fail.
2287 Fixes Savannah bug #13280.
2289 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2290 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2291 inside a variable reference. Make this function static as it's
2293 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2294 parsing an unexpanded line looking for semicolons.
2295 Fixes Savannah bug #1454.
2296 * misc.c (remove_comments): Move this to read.c and make it static
2297 as it's only used there. Call find_char_unquote() with new arg.
2298 * make.h: Remove prototypes for find_char_unquote() and
2299 remove_comments() since they're static now.
2301 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2302 its export flag and obtain its value. When we need to re-exec,
2303 increment the value and add it into the environment.
2304 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2305 * NEWS: Mention MAKE_RESTARTS.
2306 * main.c (always_make_set): New variable. Change the -B option to
2307 set this one instead.
2308 (main): When checking makefiles, only set always_make_flag if
2309 always_make_set is set AND the restarts flag is 0. When building
2310 normal targets, set it IFF always_make_set is set.
2311 (main): Avoid infinite recursion with -W, too: only set what-if
2312 files to NEW before we check makefiles if we've never restarted
2313 before. If we have restarted, set what-if files to NEW _after_ we
2315 Fixes Savannah bug #7566:
2317 2005-06-17 Paul D. Smith <psmith@gnu.org>
2319 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2320 in the prerequisites list.
2322 2005-06-12 Paul D. Smith <psmith@gnu.org>
2324 Fix Savannah bug # 1328.
2326 * configure.in: Check for atexit().
2327 * misc.c (close_stdout): Test stdout to see if writes to it have
2328 failed. If so, be sure to exit with a non-0 error code. Based on
2329 code found in gnulib.
2330 * make.h: Prototype.
2331 * main.c (main): Install close_stdout() with atexit().
2333 2005-06-10 Paul D. Smith <psmith@gnu.org>
2335 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2337 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2338 headers; make vmsWaitForChildren() static; extern vmsify().
2339 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2340 Don't create child_execute_job() here (it's in vmsjobs.c).
2341 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2343 2005-06-09 Paul D. Smith <psmith@gnu.org>
2345 * variable.c (push_new_variable_scope): File variables point
2346 directly to the global_setlist variable. So, inserting a new
2347 scope in front of that has no effect on those variables: they
2348 don't go through current_variable_set_list. If we're pushing a
2349 scope and the current scope is global, push it "the other way" so
2350 that the new setlist is in the global_setlist variable, and
2351 next points to a new setlist with the global variable set.
2352 (pop_variable_scope): Properly undo a push with the new
2354 Fixes Savannah bug #11913.
2356 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2358 * job.c (reap_children): Don't die of the command failed but
2359 the dontcare flag is set. Fixes Savannah bug #13216.
2361 * implicit.c (pattern_search): When creating a target from
2362 an implicit rule match, lookup pattern target and set precious
2363 flag in a newly created target. Fixes Savannah bug #13218.
2365 2005-05-13 Paul D. Smith <psmith@gnu.org>
2367 Implement "if... else if... endif" syntax.
2369 * read.c (eval): Push all checks for conditional words ("ifeq",
2370 "else", etc.) down into the conditional_line() function.
2371 (conditional_line): Rework to allow "else if..." clause. New
2372 return value -2 for lines which are not conditionals. The
2373 ignoring flag can now also be 2, which means "already parsed a
2374 true branch". If that value is seen no other branch of this
2375 conditional can be considered true. In the else parsing if there
2376 is extra text after the else, invoke conditional_line()
2377 recursively to see if it's another conditional. If not, it's an
2378 error. If so, raise the conditional value to this level instead
2379 of creating a new conditional nesting level. Special check for
2380 "else" and "endif", which aren't allowed on the "else" line.
2381 * doc/make.texi (Conditional Syntax): Document the new syntax.
2383 2005-05-09 Paul D. Smith <psmith@gnu.org>
2385 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2386 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2387 recurses to the w32 directory, even on non-Windows systems. Use
2388 the method suggested in the automake manual.
2389 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2390 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2392 2005-05-07 Paul D. Smith <psmith@gnu.org>
2394 * main.c (die): If we're dying with a fatal error (not that a
2395 command has failed), write back any leftover tokens before we go.
2397 * job.c (set_child_handler_action_flags): If there are jobs
2398 waiting for the load to go down, set an alarm to go off in 1
2399 second. This allows us to wake up from a potentially long-lasting
2400 read() and start a new job if the load has gone down. Turn it off
2402 (job_noop): Dummy signal handler function.
2403 (new_job): Invoke it with the new semantics.
2405 * docs/make.texi: Document secondary expansion. Various cleanups
2408 2005-05-03 Paul D. Smith <psmith@gnu.org>
2410 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2411 the targets which are to ultimately be made are called "goals";
2412 see the GNU make manual. Also, MAKECMDGOALS, etc.
2414 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2415 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2416 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2418 2005-05-02 Paul D. Smith <psmith@gnu.org>
2420 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2421 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2422 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2423 functions to vmsjobs.c. #include it into jobs.c.
2425 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2426 jobserver tokens. I found that this happens when an exported
2427 recursive variable contains a $(shell ...) function reference: in
2428 this situation we could "forget" to write back a token.
2430 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2431 we have. It's not reliable to depend on the number of children in
2432 our linked list so keep a separate count.
2433 (new_job): Check jobserver_tokens rather than children &&
2434 waiting_jobs. Increment jobserver_tokens when we get one.
2435 (free_child): If jobserver_tokens is 0, internal error. If it's
2436 >1, write a token back to the jobserver pipe (we don't write a
2437 token for the "free" job). Decrement jobserver_tokens.
2439 * main.c: Add variable master_job_slots.
2440 (main): Set it to hold the number of jobs requested if we're the
2441 master process, when using the jobserver.
2442 (die): Sanity checks: first test jobserver_tokens to make sure
2443 this process isn't holding any tokens we didn't write back.
2444 Second, if master_job_slots is set count the tokens left in the
2445 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2447 2005-04-24 Paul D. Smith <psmith@gnu.org>
2449 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2450 with -l# can lose jobserver tokens, because waiting jobs are not
2451 consulted properly when checking for the "free" token.
2453 * job.c (free_child): Count waiting_jobs as having tokens.
2454 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2455 handle jobs waiting for the load to drop.
2457 2005-04-23 Paul D. Smith <psmith@gnu.org>
2459 * main.c (main): Be careful to not core if a variable setting in
2460 the environment doesn't contain an '='. This is illegal but can
2461 happen in broken setups.
2462 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2464 2005-04-12 Paul D. Smith <psmith@gnu.org>
2466 The second expansion feature causes significant slowdown. Timing
2467 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2468 read the makefile before the feature, to 11+s to do the same
2469 operations after the feature. Additionally, memory usage
2470 increased drastically. To fix this I added some intelligence that
2471 avoids the overhead of the second expansion unless it's required.
2473 * dep.h: Add a new boolean field, need_2nd_expansion.
2475 * read.c (eval): When creating the struct dep for the target,
2476 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2477 (record_files): If there's a "%" in a static pattern rule, it gets
2478 converted to "$*" so set need_2nd_expansion to 1.
2480 * file.c (expand_deps): Rework to be more efficient. Only perform
2481 initialize_file_variables(), set_file_variables(), and
2482 variable_expand_for_file() if the need_2nd_expansion is set.
2484 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2485 (pattern_search): Ditto.
2486 * main.c (handle_non_switch_argument): Ditto.
2488 * read.c (read_all_makefiles): Ditto.
2489 (eval_makefile): Ditto.
2491 2005-04-07 Paul D. Smith <psmith@gnu.org>
2493 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2494 * variable.c (sync_Path_environment): Ditto.
2495 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2497 * main.c (main): Define the .FEATURES variable.
2498 * NEWS: Announce .FEATURES.
2499 * doc/make.texi (Special Variables): Document .FEATURES.
2501 * remake.c (check_dep): If a file is .PHONY, update it even if
2502 it's marked intermediate. Fixes Savannah bug #12331.
2504 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2506 * file.c (expand_deps): Factor out the second expansion and
2507 prerequisite line parsing logic from snap_deps().
2509 * file.c (snap_deps): Use expand_deps(). Expand and parse
2510 prerequisites of the .SUFFIXES special target first. Fixes
2511 Savannah bug #12320.
2513 2005-03-13 Paul D. Smith <psmith@gnu.org>
2515 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2518 2005-03-11 Paul D. Smith <psmith@gnu.org>
2520 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2521 available, not undefined (from Earnie Boyd).
2523 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2525 * implicit.c (pattern_search): Mark an intermediate target as
2526 precious if it happened to be a prerequisite of some (other)
2527 target. Fixes Savannah bug #12267.
2529 2005-03-09 Paul D. Smith <psmith@gnu.org>
2531 * read.c (eval_makefile): Add alloca(0).
2532 (eval_buffer): Ditto.
2534 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2536 * main.c (main): Use o_file instead of o_default when defining
2537 the .DEFAULT_TARGET special variable.
2538 * read.c (eval): Use define_variable_global() instead of
2539 define_variable() when setting new value for the .DEFAULT_TARGET
2540 special variable. Fixes Savannah bug #12266.
2542 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2544 * imlicit.c (pattern_search): Mark files for which an implicit
2545 rule has been found as targets. Fixes Savannah bug #12202.
2547 2005-03-04 Paul D. Smith <psmith@gnu.org>
2550 * doc/make.texi (Automatic Variables): Document $|.
2552 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2554 * read.c (record_files): Instead of substituting % with
2555 actual stem value in dependency list replace it with $*.
2556 This fixes stem triple expansion bug.
2558 * implicit.c (pattern_search): Copy stem to a separate
2559 buffer and make it a properly terminated string. Assign
2560 this buffer instead of STEM (which is not terminated) to
2561 f->stem. Instead of substituting % with actual stem value
2562 in dependency list replace it with $*. This fixes stem
2563 triple expansion bug.
2565 2005-03-01 Paul D. Smith <psmith@gnu.org>
2567 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2568 on Windows, as it takes a handle not a pid. Just exit.
2569 Fix from patch #3679, provided by Alessandro Vesely.
2571 * configure.in: Update check for sys_siglist[] from autoconf manual.
2572 * signame.c (strsignal): Update to use the new autoconf macro.
2574 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2576 * read.c (record_files): Add a check for the list of prerequisites
2577 of a static pattern rule being empty. Fixes Savannah bug #12180.
2579 2005-02-28 Paul D. Smith <psmith@gnu.org>
2581 * doc/make.texi (Text Functions): Update docs to allow the end
2582 ordinal for $(wordlist ...) to be 0.
2583 * function.c (func_wordlist): Fail if the start ordinal for
2584 $(wordlist ...) is <1. Matches documentation.
2585 Resolves Savannah support request #103195.
2587 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2588 previously we were stopping when !-q, exactly the opposite. This
2589 has been wrong since version 1.34, in 1994!
2590 (update_file): If we got an error don't break out to run more
2591 double-colon rules: just return immediately.
2592 Fixes Savannah bug #7144.
2594 2005-02-27 Paul D. Smith <psmith@gnu.org>
2596 * misc.c (end_of_token): Make argument const.
2597 * make.h: Update prototype.
2599 * function.c (abspath, func_realpath, func_abspath): Use
2600 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2601 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2602 * read.c (record_files): Ditto.
2603 * variable.c (do_variable_definition): Ditto.
2605 * function.c (func_error): Create a new function $(info ...) that
2606 simply prints the message to stdout with no extras.
2607 (function_table_init): Add new function to the table.
2608 * NEWS: Add $(info ...) reference.
2609 * doc/make.texi (Make Control Functions): Document it.
2611 New feature: if the system supports symbolic links, and the user
2612 provides the -L/--check-symlink-time flag, then use the latest
2613 mtime between the symlink(s) and the target file.
2615 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2616 readlink(). If both are available, define MAKE_SYMLINKS.
2617 * main.c: New variable: check_symlink_flag.
2618 (usage): Add a line for -L/--check-symlink-times to the help string.
2619 (switches): Add -L/--check-symlink-times command line argument.
2620 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2621 print a warning and disable it again.
2622 * make.h: Declare check_symlink_flag.
2623 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2624 if the file is a symlink then check each link in the chain and
2625 choose the NEWEST mtime we find as the mtime for the file. The
2626 newest mtime might be the file itself!
2627 * NEWS: Add information about this new feature.
2628 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2630 Avoid core dumps described in Savannah bug # 12124:
2632 * file.c: New variable snapped_deps remember whether we've run
2634 (snap_deps): Set it.
2635 * filedef.h: Extern it.
2636 * read.c (record_files): Check snapped_deps; if it's set then
2637 we're trying to eval a new target/prerequisite relationship from
2638 within a command script, which we don't support. Fatal.
2640 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2642 Implementation of the .DEFAULT_TARGET special variable.
2644 * read.c (eval): If necessary, update default_target_name when
2646 * read.c (record_files): Update default_target_file if
2647 default_target_name has changed.
2648 * main.c (default_target_name): Define.
2649 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2650 default_target_name is set use default_target_file as a root
2652 * filedef.h (default_target_name): Declare.
2653 * dep.h (free_dep_chain):
2654 * misc.c (free_dep_chain): Change to operate on struct nameseq
2655 and change name to free_ns_chain.
2656 * file.c (snap_deps): Update to use free_ns_chain.
2658 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2660 Implementation of the second expansion in explicit rules,
2661 static pattern rules and implicit rules.
2663 * read.c (eval): Refrain from chopping up rule's dependencies.
2664 Store them in a struct dep as a single dependency line. Remove
2665 the code that implements SySV-style automatic variables.
2667 * read.c (record_files): Adjust the code that handles static
2668 pattern rules to expand all percents instead of only the first
2669 one. Reverse the order in which dependencies are stored so that
2670 when the second expansion reverses them again they appear in
2671 the makefile order (with some exceptions, see comments in
2672 the code). Remove the code that implements SySV-style automatic
2675 * file.c (snap_deps): Implement the second expansion and chopping
2676 of dependency lines for explicit rules.
2678 * implicit.c (struct idep): Define an auxiliary data type to hold
2679 implicit rule's dependencies after stem substitution and
2682 * implicit.c (free_idep_chain): Implement.
2684 * implicit.c (get_next_word): Implement helper function for
2685 parsing implicit rule's dependency lines into words taking
2686 into account variable expansion requests. Used in the stem
2689 * implicit.c (pattern_search): Implement the second expansion
2690 for implicit rules. Also fixes bug #12091.
2692 * commands.h (set_file_variables): Declare.
2693 * commands.c (set_file_variables): Remove static specifier.
2695 * dep.h (free_dep_chain): Declare.
2696 * misc.c (free_dep_chain): Implement.
2698 * variable.h (variable_expand_for_file): Declare.
2699 * expand.c (variable_expand_for_file): Remove static specifier.
2701 * make.h (strip_whitespace): Declare.
2702 * function.c (strip_whitespace): Remove static specifier.
2704 2005-02-26 Paul D. Smith <psmith@gnu.org>
2706 * main.c (main): Check for ferror() when reading makefiles from stdin.
2707 Apparently some shells in Windows don't close pipes properly and
2710 2005-02-24 Jonathan Grant <jg@jguk.org>
2712 * configure.in: Add MinGW configuration options, and extra w32 code
2714 * Makefile.am: Add MinGW configuration options, and extra w32 code
2716 * main.c: Determine correct program string (after last \ without .exe).
2717 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2719 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2720 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2721 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2722 environment support.
2724 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2726 * function.c (func_shell): When initializing error_prefix, check
2727 that reading file name is not null. This fixes long-standing
2728 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2730 2005-02-09 Paul D. Smith <psmith@gnu.org>
2732 * maintMakefile: Update the CVS download URL to simplify them.
2733 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2734 downloading the .texi files from Savannah now.
2736 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2738 * main.c (handle_non_switch_argument): Only add variables to
2739 command_variables if they're not already there: duplicate settings
2740 waste space and can be confusing to read.
2742 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2743 this header is never included by non-WINDOWS32 code, and it
2744 requires <config.h> to define which isn't always included first.
2746 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2747 testing MINGW32 versions.
2749 * main.c (log_working_directory): flush stdout to be sure the WD
2750 change is printed before any stderr messages show up.
2752 2005-02-01 Paul D. Smith <psmith@gnu.org>
2754 * maintMakefile (po_repo): Update the GNU translation site URL.
2756 2004-12-01 Paul D. Smith <psmith@gnu.org>
2758 * main.c (main): Change char* env_shell to struct variable shell_var.
2759 * variable.c (target_environment): Use new shell_var.
2761 2004-11-30 Paul D. Smith <psmith@gnu.org>
2763 * configure.in: The old way we avoided creating build.sh from
2764 build.sh.in before build.sh.in exists doesn't work anymore; we
2765 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2766 the help!). This also keeps automake from complaining.
2767 * Makefile.am (README): Add a dummy target so automake won't
2768 complain that this file doesn't exist when we checkout from CVS.
2769 * maintMakefile (.dep_segment): Rewrite this rule since newer
2770 versions of automake don't provide DEP_FILES.
2772 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2774 Implementation of `realpath' and `abspath' built-in functions.
2776 * configure.in: Check for realpath.
2777 * function.c (abspath): Return an absolute file name that does
2778 not contain any `.' or `..' components, nor repeated `/'.
2779 * function.c (func_abspath): For each name call abspath.
2780 * function.c (func_realpath): For each name call realpath
2781 from libc or delegate to abspath if realpath is not available.
2782 * doc/make.texi (Functions for File Names): Document new functions.
2783 * doc/make.texi (Quick Reference): Ditto.
2785 2004-11-28 Paul D. Smith <psmith@gnu.org>
2787 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2788 arguments. Fixes bug #10252.
2790 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2792 * main.c (main): Set SHELL to v_noexport by default. Remember the
2793 original environment setting of SHELL in the env_shell variable.
2794 * main.h: Export new env_shell variable.
2795 * variable.c (target_environment): If we find a v_noexport
2796 variable for SHELL, add a SHELL variable with the env_shell value.
2797 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2798 * doc/make.texi (Variables/Recursion): Ditto.
2800 2004-11-28 Paul D. Smith <psmith@gnu.org>
2802 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2803 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2804 Patch by Alessandro Vesely.
2806 2004-11-12 Paul D. Smith <psmith@gnu.org>
2808 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2809 the command line if it's inside a string.
2810 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2812 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2814 * function.c (func_lastword): New function: return last word
2815 from the list of words.
2816 * doc/make.texi: Document $(lastword ). Fix broken links in
2817 Quick Reference section.
2819 2004-10-06 Paul D. Smith <psmith@gnu.org>
2821 Apply patch from Alessandro Vesely, provided with bug # 9748.
2822 Fix use of tmpnam() to work with Borland C.
2824 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2825 construction of a temporary filename, and call new function
2826 create_batch_filename().
2827 (create_batch_filename) [WINDOWS32]: New function to create a
2830 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2832 * read.c (record_target_var): Expand simple pattern-specific
2834 * variable.c (initialize_file_variables): Do not expand simple
2835 pattern-specific variable.
2837 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2839 * remake.c (update_file_1): When rebuilding makefiles inherit
2840 dontcare flag from a target that triggered update.
2842 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2844 * variable.c (initialize_file_variables): Mark pattern-specific
2845 variable as a per-target and copy export status.
2847 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2849 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2851 * implicit.c (pattern_search): When considering an implicit rule's
2852 prerequisite check that it is actually a target rather then
2853 just an entry in the file hashtable.
2855 2004-09-21 Paul D. Smith <psmith@gnu.org>
2857 * read.c (readstring): Fix some logic errors in backslash handling.
2858 (eval): Remove some unnecessary processing in buffer handling.
2859 (record_target_var): Assert that parse_variable_definition() succeeded.
2860 Reported by: Markus Mauhart <qwe123@chello.at>.
2862 * misc.c: Removed the sindex() function. All instances of this
2863 function were trivially replaceable by the standard strstr()
2864 function, and that function will always have better (or certainly
2865 no worse) performance than the very simple-minded algorithm
2866 sindex() used. This can matter with complex makefiles.
2867 * make.h: Remove the prototype for sindex().
2868 * function.c (subst_expand): Convert sindex() call to strstr().
2869 This means we no longer need to track the TLEN value so remove that.
2870 (func_findstring): Convert sindex() to strstr().
2871 * commands.c (chop_commands): Convert sindex() calls to strstr().
2872 Suggested by: Markus Mauhart <qwe123@chello.at>.
2874 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2875 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2876 If SHELL is set to CMD.EXE then assume it's batch-mode and
2877 non-unixy. I wrote the code differently from the patch, though,
2878 to make it safer. This also resolves bug #9174.
2880 2004-09-20 Paul D. Smith <psmith@gnu.org>
2882 * expand.c (variable_expand_string): Modify to invoke
2883 patsubst_expand() instead of subst_expand(); the latter didn't
2884 handle suffix patterns correctly.
2885 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2886 was used only from variable_expand_string() and is no longer used
2888 (func_subst): Ditto, on call to subst_expand().
2889 (patsubst_expand): Require the percent pointers to point to the
2890 character after the %, not to the % itself.
2891 * read.c (record_files): New call criteria for patsubst_expand().
2892 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2893 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2895 2004-09-19 Paul D. Smith <psmith@gnu.org>
2897 * function.c (subst_expand): Fix a check in by_word: look for a
2898 previous blank if we're beyond the beginning of the string, not
2899 the beginning of the word.
2900 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2902 2004-05-16 Paul D. Smith <psmith@gnu.org>
2904 * remake.c (update_goal_chain): Change the argument specifying
2905 whether we're rebuilding makefiles to be a global variable,
2906 REBUILDING_MAKEFILES.
2907 (complain): Extract the code that complains about no rules to make
2908 a target into a separate function.
2909 (update_file_1): If we tried to rebuild a file during the makefile
2910 rebuild phase and it was dontcare, then no message was printed.
2911 If we then try to build the same file during the normal build,
2912 print a message this time.
2913 (remake_file): Don't complain about un-remake-able files when
2914 we're rebuilding makefiles.
2916 2004-05-11 Paul D. Smith <psmith@gnu.org>
2918 * job.c (construct_command_argv_internal): OS/2 patches from
2919 Andreas Buening <andreas.buening@nexgo.de>.
2921 2004-05-10 Paul D. Smith <psmith@gnu.org>
2923 * remake.c (update_file): Don't walk the double-colon chain unless
2924 this is a double-colon rule. Fix suggested by Boris Kolpackov
2925 <boris@kolpackov.net>.
2927 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2928 * readme.vms: New section describing OpenVMS support and issues.
2929 * default.c (default_variables): Add support for IA64.
2930 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2931 without some privilege aborts make with the error
2932 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2933 pressing Ctrl+Y and the input device is no terminal. The change
2934 catches this error and just continues.
2936 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2938 2004-04-25 Paul D. Smith <psmith@gnu.org>
2940 * commands.c (set_file_variables): Set $< properly in the face of
2941 order-only prerequisites.
2942 Patch from Boris Kolpackov <boris@kolpackov.net>
2944 2004-04-21 Bob Byrnes <byrnes@curl.com>
2946 * main.c (main): Notice failures to remake makefiles.
2948 2004-03-28 Paul D. Smith <psmith@gnu.org>
2950 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2952 * job.c: No default shell for RISC OS.
2953 (load_too_high): Hard-code the return to 1.
2954 (construct_command_argv_internal): No sh_chars or sh_cmds.
2955 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2957 2004-03-20 Paul D. Smith <psmith@gnu.org>
2959 * variable.c (do_variable_definition): Don't append from the
2960 global set if a previous non-appending target-specific variable
2961 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2964 * expand.c (reference_variable): Don't give up on variables with
2965 no value that have the target-specific append flag set: they might
2966 have a value after all. Reported by Oliver Schmidt
2967 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2968 <nikulin@dx1cmd.inp.nsk.su>.
2970 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2971 refer to absolute pathnames in directories that don't exist: some
2972 portion of the makefile could create those directories before we
2973 match the pattern. Fixes bugs #775 and #108.
2975 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2977 * main.c (main): Free makefile_mtimes if we have any.
2978 * README.W32.template: Update documentation for the current status
2979 of the MS-Windows port.
2980 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2981 environment variable is sometimes already defined which causes the
2983 * main.c (debug_signal_handler): Only define this function if
2984 SIGUSR1 is available.
2986 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2988 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2989 * README.OS2.template: Documentation updates.
2990 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2991 link line for safety.
2992 * maintMakefile (build.sh.in): Remove an extraneous ")".
2993 * job.c (child_execute_job): Close saved FDs.
2994 * job.c (exec_command) [OS/2]: exec_command(): If the command
2995 can't be exec'ed and if the shell is not Unix-sh, then try again
2996 with argv = { "cmd", "/c", ... }. Normally, this code is never
2997 reached for the cmd shell unless the command really doesn't exist.
2998 (construct_command_argv_internal) [OS/2]: The code for cmd
2999 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3000 The CMD builtin commands are case insensitive so use strcasecmp().
3002 2004-03-19 Paul D. Smith <psmith@gnu.org>
3004 * read.c (do_define): Re-order line counter increment so the count
3005 is accurate (we were losing one line per define). Reported by
3006 Dave Yost <Dave@Yost.com>.
3008 2004-03-06 Paul D. Smith <psmith@gnu.org>
3010 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3012 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3013 * misc.c (message,error,fatal): Ditto.
3014 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3015 * config.h.W32.template: Ditto.
3016 * config.h-vms.template: Ditto.
3017 * config.ami.template: Ditto.
3019 2004-03-04 Paul D. Smith <psmith@gnu.org>
3021 * README.template: Add a note about broken /bin/sh on SunOS
3022 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3024 * misc.c (message, error, fatal): Don't use "..." if we're using
3025 varargs. ansi2knr should handle this but it doesn't work: it
3026 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3027 done. On many systems (SunOS for example) va_dcl is a #define.
3028 So, force the use of the non-"..." version on pre-ANSI compilers.
3030 * maintMakefile (sign-dist): Create some rules to help automate
3031 the new GNU ftp upload method.
3033 2004-02-24 Paul D. Smith <psmith@gnu.org>
3035 * config.h.W32.template: Add HAVE_STDARG_H
3036 * config.h-vms.template: Ditto.
3037 * config.ami.template: Ditto.
3039 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3041 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3042 * build_w32.bat: Remove extra "+".
3044 2004-02-23 Paul D. Smith <psmith@gnu.org>
3046 * make.h: Create an UNUSED macro to mark unused parameters.
3047 * (many): Clean up warnings by applying UNUSED, fixing
3048 signed/unsigned incompatibilities, etc.
3050 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3052 * filedef.h: Name the command_state enumeration.
3053 * file.c (set_command_state): Use the enumeration in the function
3056 * configure.in: Explicitly set SET_MAKE to empty, to disable
3057 MAKE=make even when no make already exists. Fix bug #3823.
3059 2004-02-22 Paul D. Smith <psmith@gnu.org>
3061 * maintMakefile: Perl script to clean up all non-CVS files. Use
3062 it on all the subdirectories for the cvs-clean target.
3064 * main.c (decode_switches): Require non-empty strings for all our
3065 string command-line options. Fixes Debian bug # 164165.
3067 * configure.in: Check for stdarg.h and varargs.h.
3068 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3069 for printing messages.
3070 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3075 A number of patches for OS/2 support from Andreas Buening
3076 <andreas.buening@nexgo.de>:
3078 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3079 disable the SIGCHLD handler.
3080 (reap_children) [OS/2]: Remove special handling of job_rfd.
3081 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3082 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3083 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3084 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3085 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3088 2004-02-21 Paul D. Smith <psmith@gnu.org>
3090 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3091 <mail@kristov.de> reports that if process_begin() fails we don't
3092 handle the error condition correctly in all cases.
3093 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3094 to have a newline on the message.
3096 * job.c (construct_command_argv_internal): Add "test" to UNIX
3097 sh_cmds[]. Fixes Savannah bug # 7606.
3099 2004-02-04 Paul D. Smith <psmith@gnu.org>
3101 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3102 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3103 Hartmut Becker <Hartmut.Becker@hp.com>.
3105 2004-01-21 Paul D. Smith <psmith@gnu.org>
3107 * job.c (load_too_high): Implement an algorithm to control the
3108 "thundering herd" problem when using -l to control job creation
3109 via the load average. The system only recomputes the load once a
3110 second but we can start many jobs in a second. To solve this we
3111 keep track of the number of jobs started in the last second and
3112 apply a weight to try to guess what a correct load would be.
3113 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3114 Also fixes bug #4693.
3115 (reap_children): Decrease the job count for this second.
3116 (start_job_command): Increase the job count for this second.
3118 * read.c (conditional_line): Expand the text after ifn?def before
3119 checking to see if it's a single word. Fixes bug #7257.
3121 2004-01-09 Paul D. Smith <psmith@gnu.org>
3123 * file.c (print_file): Recurse to print all targets in
3124 double-colon rules. Fixes bug #4518, reported (with patch) by
3125 Andrew Chatham <chatham@google.com>.
3127 2004-01-07 Paul D. Smith <psmith@gnu.org>
3129 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3130 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3131 AC_FUNC_SETVBUF_REVERSED.
3133 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3134 (MAKE Variable): Fix Savannah bug #4898.
3136 * job.c (construct_command_argv_internal): Add "!" to the list of
3137 shell escape chars. POSIX sh allows it to appear before a
3138 command, to negate the exit code. Fixes bug #6404.
3140 * implicit.c (pattern_search): When matching an implicit rule,
3141 remember which dependencies have the ignore_mtime flag set.
3142 Original fix provided in Savannah patch #2349, by Benoit
3143 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3145 2003-11-22 Paul D. Smith <psmith@gnu.org>
3147 * README.W32.template (Outputs): Clarification on -j with
3148 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3151 2003-11-02 Paul D. Smith <psmith@gnu.org>
3153 * function.c (func_if): Strip all the trailing whitespace from the
3154 condition, then don't expand it. Fixed bug # 5798.
3156 * expand.c (recursively_expand_for_file): If we're expanding a
3157 variable with no file context, then use the variable's context.
3160 2003-10-21 Paul D. Smith <psmith@gnu.org>
3162 * main.c (log_working_directory): Add newlines to printf()s.
3164 * README.cvs: Add a note to ignore warnings during autoreconf.
3166 * maintMakefile (po_repo): Set a new URL for PO file updates.
3167 (get-config/config.guess get-config/config.sub): Get these files
3168 from the Savannah config project instead of ftp.gnu.org.
3170 2003-10-05 Paul Eggert <eggert@twinsun.com>
3172 * main.c (main): Avoid potential subscript error if environ has
3175 2003-08-22 Paul D. Smith <psmith@gnu.org>
3177 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3178 systems which don't yet implement the C89 standard :-/.
3180 2003-07-18 Paul D. Smith <psmith@gnu.org>
3182 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3183 [WINDOWS32]: Initialize hash.
3185 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3187 * dir.c (read_dirstream): Provide a workaround for broken versions of
3188 the MinGW dirent structure.
3190 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3192 * w32/include/dirent.h: Add __MINGW32__ filter.
3194 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3196 * make.h: Add global declaration of *make_host.
3197 * main.c (print_usage): Remove local declaration of *make_host.
3198 (print_version): Display "This program built for ..." after Copyright
3201 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3203 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3204 execution of "makeinfo --html make.texi".
3206 2003-04-30 Paul D. Smith <psmith@gnu.org>
3208 * build.template: Make some changes to maybe allow this script to
3209 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3211 * README.OS2.template: New file for OS/2 support. Original
3212 contributed by Andreas Buening.
3213 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3216 2003-04-19 Paul D. Smith <psmith@gnu.org>
3218 Fix bug #1405: allow a target to match multiple pattern-specific
3221 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3222 variable.c, where they've always belonged.
3223 * rule.h: Move the prototypes and struct pattern_var as well.
3224 * variable.c (initialize_file_variables): Invoke
3225 lookup_pattern_var() in a loop, until no more matches are found.
3226 If a match is found, create a new variable set for the target's
3227 pattern variables. Then merge the contents of each matching
3228 pattern variable set into the target's pattern variable set.
3229 (lookup_pattern_var): Change this function to be usable
3230 in a loop. It takes a starting position: if NULL, start at the
3231 beginning; if non-NULL, start with the pattern variable after that
3232 position, and return the next matching pattern.
3233 (create_pattern_var): Create a unique instance of
3234 pattern-specific variables for every definition in the makefile.
3235 Don't combine the same pattern together. This allows us to
3236 process the variable handling properly even when the same pattern
3237 is used multiple times.
3238 (parse_variable_definition): New function: break out the parsing
3239 of a variable definition line from try_variable_definition.
3240 (try_variable_definition): Call parse_variable_definition to
3242 (print_variable_data_base): Print out pattern-specific variables.
3243 * variable.h (struct variable): Remember when a variable is
3244 conditional. Also remember its flavor.
3245 (struct pattern_var): Instead of keeping a variable set, we just
3246 keep a single variable for each pattern.
3247 * read.c (record_target_var): Each pattern variable contains only a
3248 single variable, not a set, so create it properly.
3249 * doc/make.texi (Pattern-specific): Document the new behavior.
3251 2003-04-17 Paul D. Smith <psmith@gnu.org>
3253 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3254 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3255 file/directory naming rules for VMS so I can't tell whether this
3258 2003-04-09 Paul D. Smith <psmith@gnu.org>
3260 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3261 DOS-style pathnames: backslash separators and drive specifiers.
3263 2003-03-28 Paul D. Smith <psmith@gnu.org>
3265 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3266 the intermediate flag on all targets. Fixes bug #2515.
3268 2003-03-24 Paul D. Smith <psmith@gnu.org>
3270 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3271 Upgrade to autoconf 2.57 and automake 1.7.3.
3273 * job.c: More OS/2 changes from Andreas Buening.
3275 * file.c (print_file): Fix variable initialization.
3278 * remake.c (notice_finished_file):
3280 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3281 some calls (like readdir()) return NULL in valid situations
3282 without resetting errno. Fixes bug #2846.
3284 2003-02-25 Paul D. Smith <psmith@gnu.org>
3286 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3288 * job.c (_is_unixy_shell) [OS/2]: New function.
3289 Set default shell to /bin/sh.
3290 (reap_children): Close the job_rfd pipe here since we don't use a
3292 (set_child_handler_action_flags): define this to empty on OS/2.
3293 (start_job_command): Close the jobserver pipe and use
3294 child_execute_job() instead of fork/exec.
3295 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3296 rather than exec'ing, then reconfigure stdin/stdout.
3297 (exec_command): Rewrite to use spawn instead of exec. Return the
3300 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3301 in DOS. Handle the TEMP environment variable as in DOS. Don't
3302 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3303 use -j in DOS mode. Use child_execute_job() instead of
3306 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3309 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3310 prototypes that return values.
3312 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3314 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3315 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3317 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3320 2003-02-24 Paul D. Smith <psmith@gnu.org>
3322 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3323 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3324 (child_execute_job) [VMS]: Handle error status properly.
3325 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3327 * function.c (func_shell): Use EINTRLOOP() while reading from the
3328 subshell pipe (Fixes bug #2502).
3329 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3331 * main.c (main): Ditto.
3333 2003-01-30 Paul D. Smith <psmith@gnu.org>
3335 * read.c (eval): eval() was not fully reentrant, because the
3336 collapsed buffer was static. Change it to be an automatic
3337 variable so that eval() can be invoked recursively.
3339 (eval): Apply patch # 1022: fix memory reference error on long
3340 target-specific variable lines.
3341 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3343 * function.c (check_numeric): Combine the is_numeric() function
3344 into this function, since it's only called from one place.
3345 Constify this function. Have it print the incorrect string in the
3346 error message. Fixes bug #2407.
3347 (strip_whitespace): Constify.
3348 (func_if): Constify.
3349 * expand.c (expand_argument): Constify.
3351 2003-01-29 Paul D. Smith <psmith@gnu.org>
3353 Fix bug # 2169, also reported by other people on various systems.
3355 * make.h: Some systems, such as Solaris and PTX, do not fully
3356 implement POSIX-compliant SA_RESTART functionality; important
3357 system calls like stat() and readdir() can still fail with EINTR
3358 even if SA_RESTART has been set on the signal handler. So,
3359 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3360 EINTR for system calls which return -1 or 0 (NULL), respectively,
3362 Also, remove the old atomic_stat()/atomic_readdir() and
3363 HAVE_BROKEN_RESTART handling.
3365 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3367 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3368 * remake.c (touch_file): Ditto.
3370 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3371 * read.c (construct_include_path): Ditto.
3372 * remake.c (name_mtime): Ditto.
3373 * vpath.c (selective_vpath_search): Ditto.
3374 * dir.c (find_directory): Ditto.
3375 (local_stat): Ditto.
3376 (find_directory): Use ENULLLOOP() to wrap opendir().
3377 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3379 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3380 atomic_readdir() handling.
3382 2003-01-22 Paul D. Smith <psmith@gnu.org>
3384 * function.c (func_call): Fix Bug #1744. If we're inside a
3385 recursive invocation of $(call ...), mask any of the outer
3386 invocation's arguments that aren't used by this one, so that this
3387 invocation doesn't "inherit" them accidentally.
3389 2002-12-05 Paul D. Smith <psmith@gnu.org>
3391 * function.c (subst_expand): Valery Khamenia reported a
3392 pathological performance hit when doing substitutions on very
3393 large values with lots of words: turns out we were invoking
3394 strlen() a ridiculous number of times. Instead of having each
3395 call to sindex() call strlen() again, keep track of how much of
3396 the text we've seen and pass the length to sindex().
3398 2002-11-19 Paul D. Smith <psmith@gnu.org>
3400 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3403 2002-11-16 Paul D. Smith <psmith@gnu.org>
3405 * NMakefile.template (OBJS): Add hash.c object file.
3406 * SMakefile.template (srcs): Ditto.
3407 * Makefile.ami (objs): Ditto.
3408 * build_w32.bat: Ditto.
3410 * Makefile.DOS.template: Remove extra dependencies.
3412 2002-10-25 Paul D. Smith <psmith@gnu.org>
3414 * expand.c (install_variable_buffer): New function. Install a new
3415 variable_buffer context and return the previous one.
3416 (restore_variable_buffer): New function. Free the current
3417 variable_buffer context and put a previously saved one back.
3418 * variable.h: Prototypes for {install,restore}_variable_buffer.
3419 * function.c (func_eval): Push a new variable_buffer context
3420 before we eval, then restore the old one when we're done.
3423 * read.c (install_conditionals): New function. Install a new
3424 conditional context and return the previous one.
3425 (restore_conditionals): New function. Free the current
3426 conditional context and put a previously saved one back.
3427 (eval): Use the {install,restore}_conditionals for "include"
3429 (eval_buffer): Use {install,restore}_conditionals to preserve the
3430 present conditional state before we evaluate the buffer.
3433 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3435 (Recursion): Add a variable index entry for CURDIR.
3437 * README.cvs: Update to appropriate versions.
3438 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3439 don't need to copy loadavg.c: automake is smart enough to create
3440 it for me. Still have a bug in automake related to ansi2knr tho.
3442 2002-10-14 Paul D. Smith <psmith@gnu.org>
3444 * remake.c (notice_finished_file): Only touch targets if they have
3445 at least one command (as per POSIX). Resolve Bug #1418.
3447 * *.c: Convert to using ANSI C-style function definitions.
3448 * Makefile.am: Enable the ansi2knr feature of automake.
3449 * configure.in: ditto.
3451 2002-10-13 Paul D. Smith <psmith@gnu.org>
3453 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3454 for automatic variable values like $^, etc. In the case of very
3455 large lists of prerequisites this causes problems. Instead reuse
3456 a static buffer (resizeable) for each variable.
3458 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3459 target-specific variable definitions. Check for it and set an
3461 (record_target_var): Set the export field to v_export if the
3462 "exported" flag is set.
3463 * doc/make.texi (Target-specific): Document the ability to use
3466 * doc/make.texi: Change the name of the section on automatic
3467 variables from "Automatic" to "Automatic Variables". Added text
3468 clarifying the scope of automatic variables.
3470 2002-10-04 Paul D. Smith <psmith@gnu.org>
3472 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3474 (record_files): Ditto.
3476 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3477 the search for the '=' to only within the enclosing parens.
3479 2002-10-03 Paul D. Smith <psmith@gnu.org>
3481 Version 3.80 released.
3483 * dir.c: Change hash functions to use K&R function definition style.
3484 * function.c: Ditto.
3486 * variable.c: Ditto.
3488 Update to automake 1.7.
3490 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3491 (pdf): Remove this target as automake now provides one.
3493 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3495 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3497 * makefile.com: Updates for GNU make 3.80.
3498 * makefile.vms: Ditto.
3500 2002-09-23 Paul D. Smith <psmith@gnu.org>
3502 * read.c (enum make_word_type): Remove w_comment.
3503 (get_next_mword): Don't treat comment characters as special; where
3504 this function is used we will never see a comment (it's stripped
3505 before we get here) and treating comments specially means that
3506 targets like "foo\#bar" aren't handled properly.
3508 2002-09-18 Paul D. Smith <psmith@gnu.org>
3510 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3512 * read.c (eval): Expansion of arguments to export/unexport was
3513 ignoring all arguments after the first one. Change the algorithm
3514 to expand the whole line once, then parse the results.
3516 2002-09-17 Paul D. Smith <psmith@gnu.org>
3518 Fix Bug #940 (plus another bug I found while looking at this):
3520 * read.c (record_target_var): enter_file() will add a new entry if
3521 it's a double-colon target: we don't want to do that in this
3522 situation. Invoke lookup_file() and only enter_file() if it does
3523 not already exist. If the file we get back is a double-colon then
3524 add this variable to the "root" double-colon target.
3526 * variable.c (initialize_file_variables): If this file is a
3527 double-colon target but is not the "root" target, then initialize
3528 the root and make the root's variable list the parent of our
3531 2002-09-13 Paul D. Smith <psmith@gnu.org>
3533 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3535 * hash.c (round_up_2): Get rid of a warning.
3537 2002-09-12 Paul D. Smith <psmith@gnu.org>
3539 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3540 so it doesn't complain about getloadavg.c.
3542 * commands.c (set_file_variables): Make sure we always alloca() at
3543 least 1 character for the value of $? (for '\0').
3545 2002-09-11 Paul D. Smith <psmith@gnu.org>
3547 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3548 macro to use RESULT instead of the incorrect _RESULT_.
3550 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3551 and atomic_readdir(). We need to #include dirent.h to get this to
3553 * misc.c (atomic_readdir): Fix typos.
3555 2002-09-10 Paul D. Smith <psmith@gnu.org>
3557 * read.c (eval): Expand variable lists given to export and
3558 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3559 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3561 * doc/make.texi (Variables/Recursion): Document this.
3562 (Conditional Syntax): And here.
3564 2002-09-09 Paul D. Smith <psmith@gnu.org>
3566 * configure.in: Check for memmove().
3568 2002-09-07 Paul D. Smith <psmith@gnu.org>
3570 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3571 Michael Sterrett <msterret@coat.com> reports that while it has
3572 SA_RESTART, it does not work properly.
3574 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3575 that invokes stat() and loops to do it again if it returns EINTR.
3576 (atomic_readdir): Ditto, with readdir().
3578 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3579 and readdir() to atomic_stat() and atomic_readdir().
3581 2002-09-04 Paul D. Smith <psmith@gnu.org>
3583 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3584 reports that GNU make sometimes doesn't recognize that targets can
3585 be made, when directories can be created as prerequisites. He
3586 reports that changing the order of predicates in the DEP->changed
3587 flag test so that lookup_file() is always performed, solves this
3590 2002-08-08 Paul D. Smith <psmith@gnu.org>
3592 * configure.in: Require a newer version of gettext.
3594 * misc.c (perror_with_name): Translate the format string (for
3595 right-to-left language support).
3596 (pfatal_with_name): Ditto.
3598 * main.c: Create a static array of strings to store the usage
3599 text. This is done to facilitate translations.
3600 (struct command_switch): Remove argdesc and description fields.
3601 (switches): Remove values for obsolete fields.
3602 (print_usage): Print each element of the usage array.
3604 * hash.c: Change function definitions to be K&R style.
3606 2002-08-02 Paul D. Smith <psmith@gnu.org>
3608 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3609 this one because it's too hard to get right. We'll look at it for
3611 * main.c (main): Don't create the .TARGETS variable.
3612 * variable.c (handle_special_var): Don't handle .TARGETS.
3614 2002-08-01 Paul D. Smith <psmith@gnu.org>
3616 * main.c (switches): Add a new option, -B (--always-make). If
3617 specified, make will rebuild all targets that it encounters even
3618 if they don't appear to be out of date.
3619 (always_make_flag): New flag.
3620 * make.h: Extern always_make_flag.
3621 * remake.c (update_file_1): Check always_make_flag; if it's set we
3622 will always rebuild any target we can, even if none of its
3623 prerequisites are newer.
3626 * doc/make.texi (Shell Function): Make it clear that make
3627 variables marked as "export" are not passed to instances of the
3630 Add new introspection variable .VARIABLES and .TARGETS.
3632 * variable.c (handle_special_var): New function. If the variable
3633 reference passed in is "special" (.VARIABLES or .TARGETS),
3634 calculate the new value if necessary. .VARIABLES is handled here:
3635 walk through the hash of defined variables and construct a value
3636 which is a list of the names. .TARGETS is handled by
3637 build_target_list().
3638 (lookup_variable): Invoke handle_special_var().
3639 * file.c (build_target_list): Walk through the hask of known files
3640 and construct a list of the names of all the ones marked as
3642 * main.c (main): Initialize them to empty (and as simple variables).
3643 * doc/make.texi (Special Variables): Document them.
3644 * NEWS: Mention them.
3646 * variable.h (struct variable): Add a new flag "exportable" which
3647 is true if the variable name is valid for export.
3648 * variable.c (define_variable_in_set): Set "exportable" when a new
3649 variable is defined.
3650 (target_environment): Use the "exportable" flag instead of
3651 re-checking the name here... an efficiency improvement.
3653 2002-07-31 Paul D. Smith <psmith@gnu.org>
3655 * config.h-vms.template: Updates to build on VMS. Thanks to
3656 Brian_Benning@aksteel.com for helping verify the build.
3657 * makefile.com: Build the new hash.c file.
3658 * hash.h: Use strcpmi(), not stricmp(), in the
3659 HAVE_CASE_INSENSITIVE_FS case.
3661 2002-07-30 Paul D. Smith <psmith@gnu.org>
3663 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3664 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3665 Reported by <Brian_Benning@aksteel.com>.
3667 2002-07-10 Paul D. Smith <psmith@gnu.org>
3669 * variable.c (pop_variable_scope): Remove variable made unused by
3670 new hash infrastructure.
3671 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3672 comparisons as well as name comparisons.
3673 * variable.h: Add a prototype for new hash_init_function_table().
3674 * file.c (lookup_file): Remove variables made unused by new hash
3676 * dir.c (directory_contents_hash_2): Missing return of hash value.
3677 (dir_contents_file_exists_p): Remove variables made unused by new
3678 hash infrastructure.
3681 Installed Greg McGary's integration of the hash functions from the
3682 GNU id-utils package:
3684 2002-07-10 Greg McGary <greg@mcgary.org>
3686 * scripts/functions/filter-out: Add literals to to the
3687 pattern space in order to add complexity, and trigger
3688 use of an internal hash table. Fix documentation strings.
3689 * scripts/targets/INTERMEDIATE: Reverse order of files
3690 passed to expected `rm' command.

3784 2002-07-10 Paul D. Smith <psmith@gnu.org>
3786 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3787 prerequisite list. A real SysV make will expand the entire
3788 prerequisites list _twice_: we don't do that as it's a big
3789 backward-compatibility problem. We only replace those specific
3792 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3793 references left in the list of prerequisites. Check for .POSIX as
3794 we record targets, so we can disable non-POSIX behavior while
3795 reading makefiles as well as running them.
3796 (eval): Check the prerequisite list to see if we have anything
3797 that looks like a SysV prerequisite variable reference.
3799 2002-07-09 Paul D. Smith <psmith@gnu.org>
3801 * doc/make.texi (Prerequisite Types): Add a new section describing
3802 order-only prerequisites.
3804 * read.c (uniquize_deps): If we have the same file as both a
3805 normal and order-only prereq, get rid of the order-only prereq,
3806 since the normal one supersedes it.
3808 2002-07-08 Paul D. Smith <psmith@gnu.org>
3810 * AUTHORS: Added Greg McGary to the AUTHORS file.
3811 * NEWS: Blurbed order-only prerequisites.
3812 * file.c (print_file): Show order-only deps properly when printing
3815 * maintMakefile: Add "update" targets for wget'ing the latest
3816 versions of various external files. Taken from Makefile.maint in
3819 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3820 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3822 2002-07-07 Paul D. Smith <psmith@gnu.org>
3824 * po/*.po: Remove. We'll use wget to retrieve them at release
3827 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3828 rather than a shell you get an exception. Make sure we look up
3829 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3831 * remake.c (notice_finished_file): Fix handling of -t flag.
3832 Patch provided by Henning Makholm <henning@makholm.net>.
3834 * implicit.c (pattern_search): Some systems apparently run short
3835 of stack space, and using alloca() in this function caused an
3836 overrun. I modified it to use xmalloc() on the two variables
3837 which seemed like they might get large. Fixes Bug #476.
3839 * main.c (print_version): Update copyright notice to conform with
3841 (print_usage): Update help output.
3843 * function.c (func_eval): Create a new make function, $(eval
3844 ...). Expand the arguments, put them into a buffer, then invoke
3845 eval_buffer() on the resulting string.
3846 (func_quote): Create a new function, $(quote VARNAME). Inserts
3847 the value of the variable VARNAME without expanding it any
3850 * read.c (struct ebuffer): Change the linebuffer structure to an
3851 "eval buffer", which can be either a file or a buffer.
3852 (eval_makefile): Move the code in the old read_makefile() which
3853 located a makefile into here: create a struct ebuffer with that
3854 information. Have it invoke the new function eval() with that
3856 (eval_buffer): Create a new function that creates a struct ebuffer
3857 that holds a string buffer instead of a file. Have it invoke
3858 eval() with that ebuffer.
3859 (eval): New function that contains the guts of the old
3860 read_makefile() function: this function parses makefiles. Obtains
3861 data to parse from the provided ebuffer. Some modifications to
3862 make the flow of the function cleaner and clearer. Still could
3863 use some work here...
3864 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3865 contents of the define/endef variable from the ebuffer.
3866 (readstring): Read the next line from a string-style ebuffer.
3867 (readline): Read the next line from an ebuffer. If it's a string
3868 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3871 * dep.h (eval_buffer): Prototype eval_buffer();
3873 * variable.c (do_variable_definition): Make sure that all
3874 non-target-specific variables are registered in the global set.
3875 If we're invoked from an $(eval ...) we might be inside a $(call
3876 ...) or other function which has pushed a variable scope; we still
3877 want to define our variables from evaluated makefile code in the
3880 2002-07-03 Greg McGary <greg@mcgary.org>
3882 * dep.h (struct dep) [ignore_mtime]: New member.
3883 [changed]: convert to a bitfield.
3884 * implicit.c (pattern_search): Zero ignore_mtime.
3885 * main.c (main, handle_non_switch_argument): Likewise.
3886 * rule.c (convert_suffix_rule): Likewise.
3887 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3888 (read_makefile): Parse '|' in prerequisite list.
3889 (uniquize_deps): Consider ignore_mtime when comparing deps.
3890 * remake.c (update_file_1, check_dep): Don't force remake for
3891 dependencies that have d->ignore_mtime.
3892 * commands.c (FILE_LIST_SEPARATOR): New constant.
3893 (set_file_variables): Don't include a
3894 prerequisite in $+, $^ or $? if d->ignore_mtime.
3897 2002-06-18 Paul D. Smith <psmith@gnu.org>
3899 * make.texinfo: Updates for next revision. New date/rev/etc.
3900 Recreate all Info menus. Change license on the manual to the GNU
3901 Free Documentation License. A number of typos.
3902 (Variables Simplify): Don't use "-" before it's defined.
3903 (Automatic Prerequisites): Rewrite the target example to work
3904 properly if the compile fails. Remove incorrect comments about
3905 how "set -e" behaves.
3906 (Text Functions): Move the "word", "wordlist", "words", and
3907 "firstword" functions here, from "File Name Functions".
3908 * make-stds.texi: Update from latest GNU version.
3909 * fdl.texi: (created) Import the latest GNU version.
3911 2002-06-06 Paul D. Smith <psmith@gnu.org>
3913 * variable.c (do_variable_definition): New function: extract the
3914 part of try_variable_definition() that actually sets the value
3915 into a separate function.
3916 (try_variable_definition): Call do_variable_definition() after
3917 parsing the variable definition string.
3918 (define_variable_in_set): Make the name argument const.
3920 * variable.h (enum variable_flavor): Make public.
3921 (do_variable_definition): Create prototype.
3923 * read.c (read_all_makefiles): Create a new built-in variable,
3925 (read_makefile): Add each makefile read in to this variable value.
3927 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3929 * Makefile.DOS.template: Tweak according to changes in the
3930 distribution. Add back the dependencies of *.o files.
3932 * configh.dos.template: Synchronize with config.h.in.
3934 2002-05-09 Paul D. Smith <psmith@gnu.org>
3936 * file.c (file_timestamp_now): Use K&R function declaration.
3938 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3939 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3940 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3941 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3942 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3943 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3944 nlist.n_name is a pointer rather than an array.
3946 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3947 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3948 * configure.in: Use it instead of the old version.
3950 * main.c (main): Prefer setvbuf() to setlinebuf().
3952 2002-05-08 Paul D. Smith <psmith@gnu.org>
3954 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3955 (loadavg_LDADD): Ditto.
3957 2002-04-29 Paul D. Smith <psmith@gnu.org>
3959 * expand.c (recursively_expand_for_file): Rename
3960 recursively_expand() to recursively_expand_for_file() and provide
3961 an extra argument, struct file. If the argument is provided, set
3962 the variable scope to that of the file before expanding.
3963 * variable.h (recursively_expand): Make this a macro that invokes
3964 recursively_expand_for_file() with a NULL file pointer.
3965 * variable.c (target_environment): Call the renamed function and
3966 provide the current file context.
3967 Fixes Debian bug #144306.
3969 2002-04-28 Paul D. Smith <psmith@gnu.org>
3971 Allow $(call ...) user-defined variables to be self-referencing
3972 without throwing an error. Allows implementation of transitive
3973 closures, among other possibly useful things.
3974 Requested by: Philip Guenther <guenther@sendmail.com>
3976 * variable.h (struct variable): Add a new field: exp_count, and
3977 new macros to hold its size and maximum value.
3978 (warn_undefined): Make this a macro.
3979 * variable.c (define_variable_in_set): Initialize it.
3980 * expand.c (recursively_expand): If we detect recursive expansion
3981 of a variable, check the exp_count field. If it's greater than 0
3982 allow the recursion and decrement the count.
3983 (warn_undefined): Remove this (now a macro in variable.h).
3984 * function.c (func_call): Before we expand the user-defined
3985 function, modify its exp_count field to contain the maximum
3986 number of recursive calls we'll allow. After the call, reset it
3989 2002-04-21 Paul D. Smith <psmith@gnu.org>
3991 Modified to use latest autoconf (2.53), automake (1.6.1), and
3992 gettext (0.11.1). We're using gettext's new "external" support,
3993 to avoid including libintl source with GNU make.
3995 * README.cvs: New file. Explain how to build GNU make from CVS.
3997 * configure.in: Modify checking for the system glob library.
3998 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3999 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4000 etc. will manage it correctly). Set an automake conditional
4001 USE_LOCAL_GLOB to decide whether to compile the glob library.
4003 * getloadavg.c (main): Include make.h in the "TEST" program to
4006 * Makefile.am: Remove special rules for loadavg. Replace them
4007 with Automake capabilities for building extra programs.
4009 * signame.c: This file does nothing if the system provide
4010 strsignal(). If not, it implements strsignal(). If the system
4011 doesn't define sys_siglist, then we make our own; otherwise we use
4013 * signame.h: Removed.
4015 * main.c (main): No need to invoke signame_init(). Update copyright.
4017 * ABOUT-NLS: Removed.
4018 * gettext.c: Removed.
4019 * gettext.h: Get a simplified copy from the gettext package.
4021 * i18n/*.po: Moved to po/.
4024 * config/*: Created. Contains package configuration helper files.
4025 * config.guess, config.sub: Moved to config directory.
4027 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4028 Rework to use new-style autoconf features. Use the "external"
4029 mode for gettext. Make the build.sh config file conditional on
4030 whether build.sh.in exists, to avoid autoconf errors.
4031 * acinclude.m4: Removed almost all macros as being obsolete.
4032 Rewrote remaining macros to use AC_DEFINE.
4033 * acconfig.h: Removed.
4035 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4036 conditional to handle customs support. Remove special handling
4039 2002-04-20 Paul D. Smith <psmith@gnu.org>
4041 * function.c (func_call): Don't mark the argument variables $1,
4042 etc. as recursive. They've already been fully expanded so
4043 there's no need to do it again, and doing so strips escaped $'s.
4044 Reported by Sebastian Glita <glseba@yahoo.com>.
4046 * remake.c (notice_finished_file): Walk through double-colon
4047 entries via the prev field, not the next field!
4048 Reported by Greg McGary <greg@mcgary.org>.
4050 * main.c (main): If the user specifies -q and asks for a specific
4051 target which is a makefile, we got an assert. In that case it
4052 turns out we should continue normally instead.
4054 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4056 * i18n/he.po: Installed a new translation.
4058 2002-01-07 Paul D. Smith <psmith@gnu.org>
4060 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4062 2001-12-04 Paul D. Smith <psmith@gnu.org>
4064 * i18n/ja.po: Installed an updated translation.
4066 2001-09-06 Paul Eggert <eggert@twinsun.com>
4068 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4069 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4071 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4073 (main): Get rid of any avoidable limit on stack size.
4075 2001-09-04 Paul D. Smith <psmith@gnu.org>
4077 * i18n/da.po: Installed an updated translation.
4079 2001-08-03 Paul D. Smith <psmith@gnu.org>
4081 * i18n/fr.po: Installed an updated translation.
4082 Resolves Debian bug #106720.
4084 2001-06-13 Paul D. Smith <psmith@gnu.org>

4089 2001-06-11 Paul D. Smith <psmith@gnu.org>
4091 * i18n/ko.po: Installed a new translation.
4093 2001-05-06 Paul D. Smith <psmith@gnu.org>
4095 Modify the EINTR handling.
4097 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4098 the way in which we manage the file descriptor/signal handler race
4099 trap to be more efficient.
4101 2001-05-06 Paul Eggert <eggert@twinsun.com>
4103 Restart almost all system calls that are interrupted, instead
4104 of worrying about EINTR. The lone exception is the read() for
4107 * configure.in (HAVE_SA_RESTART): New macro.
4108 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4109 * main.c (main): Use SA_RESTART instead of the old,
4110 nonstandard SA_INTERRUPT.
4112 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4113 * main.c (bsd_signal): New function or macro,
4114 if the implementation doesn't supply it.
4115 (The bsd_signal function will be in POSIX 1003.1-200x.)
4116 (HANDLESIG): Remove.
4117 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4119 * make.h (EINTR_SET): Remove.
4120 (SA_RESTART): New macro.
4122 * arscan.c (ar_member_touch): Don't worry about EINTR.
4123 * function.c (func_shell): Likewise.
4124 * job.c (reap_children, free_child, new_job): Likewise.
4125 * main.c (main): Likewise.
4126 * remake.c (touch_file, name_mtime): Likewise.
4128 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4129 if fstat failed with errno!=EINTR, the error was ignored.
4131 * job.c (set_child_handler_action_flags): New function.
4132 (new_job): Use it to temporarily clear the SIGCHLD action flags
4133 while reading the token.

4137 * job.c (start_job_command): Don't add define/endef per-line flags
4138 to the top-level flags setting.
4140 2001-04-03 Paul D. Smith <psmith@gnu.org>
4142 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4143 bit on error, so check for odd return values, not non-0 return
4145 (VMS_get_member_info): Calculate the timezone differences correctly.
4146 Reported by John Fowler <jfowler@nyx.net>.
4149 2001-03-14 Paul D. Smith <psmith@gnu.org>
4151 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4152 value before invoking define_variable().
4153 Reported by John Fowler <jfowler@nyx.net>.
4155 2001-02-07 Paul D. Smith <psmith@gnu.org>
4157 * read.c (record_target_var): If we reset the variable due to a
4158 command-line variable setting overriding it, turn off the "append"
4161 2001-01-17 Paul D. Smith <psmith@gnu.org>
4163 * variable.c (lookup_variable) [VMS]: When getting values from the
4164 environment, allocate enough space for the _value_ plus escapes,
4165 not enough space for the name plus escapes :-/.
4166 Reported by John Fowler <jfowler@nyx.net>.
4168 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4169 warnings that make generates, so it doesn't look like an error.
4170 Reported by Karl Berry <karl@gnu.org>.
4173 Fix for PR/2020: Rework appended target-specific variables. I'm
4174 fairly confident this algorithm is finally correct.
4176 * expand.c (allocated_variable_append): Rewrite. Instead of
4177 expanding each appended variable then adding all the expanded
4178 strings together, we append all the unexpanded values going up
4179 through the variable set contexts, then expand the final result.
4180 This behaves just like non-target-specific appended variable
4181 values, while the old way didn't in various corner cases.
4182 (variable_append): New function: recursively append the unexpanded
4183 value of a variable, walking from the outermost variable scope to
4185 * variable.c (lookup_variable): Remove the code that looked up the
4186 variable set list if the found variable was "append". We don't
4188 (lookup_variable_in_set): Make this non-static so we can use it
4190 (try_variable_definition): Use lookup_variable_in_set() rather
4191 than faking out current_variable_set_list by hand (cleanup).
4192 * variable.h: Add a prototype for the now non-static
4193 lookup_variable_in_set().
4195 2000-11-17 Paul D. Smith <psmith@gnu.org>
4197 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4198 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4199 before throwing a fit.
4201 2000-11-17 Paul D. Smith <psmith@gnu.org>
4203 * read.c (readline): CRLF calculations had a hole, if you hit the
4204 buffer grow scenario just right. Reworked the algorithm to avoid
4205 the need for len or lastlen at all. Problem description with
4206 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4208 2000-10-24 Paul D. Smith <psmith@gnu.org>
4210 * gettext.c (SWAP): Declare this with the prototype, otherwise
4211 some systems don't work (non-32-bit? Reported for Cray T3E).
4212 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4214 2000-10-05 Paul D. Smith <psmith@gnu.org>
4216 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4217 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4219 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4221 2000-09-22 Paul D. Smith <psmith@gnu.org>
4223 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4224 parts of the real gettext.h here, and we expect to really include
4225 the real gettext.h later. If we keep this #define, it's ignored.
4227 2000-09-21 Paul D. Smith <psmith@gnu.org>
4229 * main.c (log_working_directory): Rework the text to use complete
4230 sentences, to make life simpler for the translators.
4232 2000-08-29 Paul D. Smith <psmith@gnu.org>
4234 * file.c (remove_intermediates): Print a debug message before we
4235 remove intermediate files, so the user (if she uses -d) knows
4238 2000-08-21 Paul D. Smith <psmith@gnu.org>
4240 * variable.c (try_variable_definition): Change how we handle
4241 target-specific append variable defns: instead of just setting the
4242 value, expand it as an append _but_ only within the current
4243 target's context. Otherwise we lose all but the last value if the
4244 variable is appended more than once within the current target
4245 context. Fixes PR/1831.
4247 2000-08-16 Paul D. Smith <psmith@gnu.org>
4249 * function.c (func_shell): Nul-terminate the buffer before
4250 printing an exec error message (just in case it's not!).
4251 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4253 2000-07-25 Paul D. Smith <psmith@gnu.org>
4255 * job.c (construct_command_argv_internal): Add "~" to the list of
4256 sh_chars[] which disallow optimizing out the shell call.
4258 2000-07-23 Paul Eggert <eggert@twinsun.com>
4260 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4261 supersedes --disable-nsec-timestamps.
4262 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4263 * README: Remove --disable-nsec-timestamps.
4265 * filedef.h (struct file.low_resolution_time): New member.
4266 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4267 * remake.c (update_file_1):
4268 Avoid spurious rebuilds due to low resolution time stamps,
4269 generalizing the earlier code that applied only to archive members.
4270 (f_mtime): Archive members always have low resolution time stamps.
4272 * configure.in: Remove --disable-nsec-timestamps, as this has
4273 been superseded by .LOW_RESOLUTION_TIME.
4275 2000-07-23 Paul Eggert <eggert@twinsun.com>
4277 * configure.in (enable_nsec_timestamps): Renamed from
4278 make_cv_nsec_timestamps, since enable/disable options
4279 shouldn't be cached.
4281 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4282 and Paul Eggert <eggert@twinsun.com>
4284 * file.c (file_timestamp_now):
4285 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4286 so that clock_gettime is not linked unless needed.
4288 * filedef.h (FILE_TIMESTAMP_HI_RES):
4289 Remove definition; "configure" now does this.
4291 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4292 to before high resolution file timestamp check,
4293 since that check now uses uintmax_t.
4294 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4295 high resolution file timestamps.
4296 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4297 so that we don't link in clock_gettime unnecessarily.
4299 2000-07-17 Paul D. Smith <psmith@gnu.org>
4301 * i18n/ja.po: New version of the translation file.
4303 2000-07-07 Paul D. Smith <psmith@gnu.org>
4305 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4306 the offset calculation.
4307 (name_mtime): Replace EINTR test with EINTR_SET macro.
4309 2000-07-07 Paul Eggert <eggert@twinsun.com>
4313 * remake.c (update_file_1):
4314 Avoid spurious rebuilds of archive members due to their
4315 timestamp resolution being only one second.
4316 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4317 the clock's resolution being lower than file timestamps'.
4318 When warning about future timestamps, report only the discrepancy,
4319 not the absolute value of the timestamp and the current time.
4321 * file.c (file_timestamp_now): New arg RESOLUTION.
4322 * filedef.h (file_timestamp_now): Likewise.
4323 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4325 2000-07-05 Paul D. Smith <psmith@gnu.org>
4327 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4328 to listp. Fixes PR/1793.
4330 2000-06-26 Paul Eggert <eggert@twinsun.com>
4332 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4334 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4336 * remake.c (f_mtime): Remove unused var memtime.
4338 2000-06-25 Martin Buchholz <martin@xemacs.org>
4340 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4341 Ran spell-check on make.texinfo.
4343 2000-06-23 Paul D. Smith <psmith@gnu.org>
4345 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4346 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4347 * make.h: Define these macros.
4349 * Version 3.79.1 released.
4351 * configure.in: Add a new option, --disable-nsec-timestamps, to
4352 avoid using sub-second timestamps on systems that support it. It
4353 can lead to problems, e.g. if your makefile relies on "cp -p".
4354 * README.template: Document the issue with "cp -p".
4356 * config.guess, config.sub: Updated.
