555 double-colons have a different meaning. Savannah bug #27497.
557 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
559 * configh.dos.template: Remove unconditional definition of
560 SYS_SIGLIST_DECLARED.
561 Include <sys/version.h> because ports of GCC 4.3.0 and later no
562 longer include it, so macros like __DJGPP_MINOR__ are no longer
563 defined automatically.
565 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
566 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
567 instead of using the hardcoded ones.
568 (SUBDIRS): doc subdir added.
569 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
570 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
571 create html formated docs. texi2html may not be ported to DOS.
572 (make.info, make.dvi, make.ps, make.html): Make targets depend on
574 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
575 -I switch to look in ./ instead of ./doc.
576 (html): Target depend on html-recursive instead of make_1.html.
577 (make_1.html): Removed.
578 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
579 (all-recursive): Allow for more than one subdir in the build
581 (mostlyclean-recursive, clean-recursive, distclean-recursive)
582 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
583 (tags-recursive): Allow for more than one subdir in the build
585 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
586 targets. Enter into doc/ to produce the targets.
587 (all-am): $(INFO_DEPS) replaced by info.
589 2009-09-26 Paul Smith <psmith@gnu.org>
591 * read.c (record_files): Use free_ns() to free struct nameseq.
594 * rule.c (freerule): Use free_dep_chain().
596 * read.c (record_files): Free FILENAMES chain for implicit rules.
597 (eval): Static pattern targets go into the string cache.
599 * function.c (string_glob): Free NAME in the nameseq chain.
601 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
603 * implicit.c (pattern_search): Terminate early if we haven't
604 found any rules to try (performance improvement).
606 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
608 * implicit.c (pattern_search): Merge three parallel arrays,
609 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
610 of struct TRYRULE. In the old version the latter two arrays
611 had insufficient length.
613 2009-09-24 Paul Smith <psmith@gnu.org>
615 * implicit.c (pattern_search): Add back support for order-only
616 prerequisites for secondary expansion implicit rules, that were
617 accidentally dropped. If we find a "|", enable order-only mode
618 and set IGNORE_MTIME on all deps that are seen afterward.
619 (pattern_search): Fix memory leaks: for intermediate files where
620 we've already set the file variable and pattern variable sets, be
621 sure to either save or free them as appropriate.
623 2009-09-23 Paul Smith <psmith@gnu.org>
625 Rework the way secondary expansion is stored, for efficiency.
626 This changes secondary expansion so that ONLY WHEN we know we have
627 a possibility of needing secondary expansion, do we defer the
628 secondary expansion. This means more parsing the deps but we use
629 a lot less memory (due to the strcache). Also, this fixes
632 * read.c (eval): Don't parse the dep string here anymore.
633 (record_files): Take the dep argument as an unparsed string. If
634 secondary expansion is enabled AND the prereq string has a '$' in
635 it, then set NEED_2ND_EXPANSION and keep the entire string.
636 Otherwise, parse the dep string here to construct the dep list
637 with the names in the strcache.
639 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
640 duplicate the name string (others are in the strcache).
642 * implicit.c: Remove struct idep and free_idep_chain(): unused.
643 (struct patdeps): New structure to store prereq information.
644 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
645 which prerequisites need expansion, and expand only those.
647 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
648 and enter_prereqs(). split_prereqs() takes a fully-expanded string
649 and splits it into a DEP list, handling order-only prereqs.
650 (enter_prereqs): This function enters a list of DEPs into the file
651 database. If there's a stem defined, expand any pattern chars.
652 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
653 set. Use the above functions.
654 (snap_deps): Only perform second expansion on prereqs that need it,
655 as defined by the NEED_2ND_EXPANSION flag.
656 (print_prereqs): New function to print the prereqs
657 (print_file): Call print_prereqs() rather than print inline.
659 * hash.h (STRING_COMPARE): Take advantage of strcache() by
661 (STRING_N_COMPARE): Ditto.
662 (ISTRING_COMPARE): Ditto.
664 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
665 (parse_file_seq): Return void*
666 * read.c (parse_file_seq): Return void*.
667 (eval): Invoke macroized version of parse_file_seq()
668 * default.c (set_default_suffixes): Ditto.
669 * file.c (split_prereqs): Ditto.
670 * function.c (string_glob): Ditto.
671 * main.c (main): Ditto.
672 * rule.c (install_pattern_rule): Ditto.
674 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
676 2009-09-16 Paul Smith <psmith@gnu.org>
678 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
680 * dep.h: Create alloc_dep() / free_dep() macros.
682 * implicit.c (pattern_search): Take advantage of the new
683 parse_file_seq() to add the directory prefix to each prereq.
685 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
686 all. Avoid reversing chains. Support adding prefixes.
687 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
688 cached/non-cached results.
689 (eval): Remove multi_glob() & invoke new parse_file_seq().
690 * rule.c (install_pattern_rule): Ditto.
691 * main.c (main): Ditto.
692 * implicit.c (pattern_search): Ditto.
693 * function.c (string_glob): Ditto.
694 * file.c (parse_prereqs): Ditto.
695 * default.c (set_default_suffixes): Ditto.
697 * variable.c (parse_variable_definition): Don't run off the end of
698 the string if it ends in whitespace (found with valgrind).
700 * commands.c (set_file_variables): Keep space for all targets in
701 $? if -B is given (found with valgrind).
703 2009-09-15 Paul Smith <psmith@gnu.org>
705 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
706 (xcalloc): Add new function.
707 * make.h: New declarations.
709 * ar.c (ar_glob_match): New calling method for concat().
710 * main.c (main): Ditto.
711 (decode_env_switches): Ditto.
712 * read.c (eval_makefile): Ditto.
713 (tilde_expand): Ditto.
714 (parse_file_seq): Ditto.
715 * variable.c (target_environment): Ditto.
716 (sync_Path_environment): Ditto.
718 * ar.c (ar_glob_match): Use xcalloc().
719 * dir.c (file_impossible): Ditto.
720 * file.c (enter_file): Ditto.
721 * job.c (new_job): Ditto.
722 * read.c (parse_file_seq): Ditto.
723 * vmsfunctions.c (opendir): Ditto.
725 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
727 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
728 inside the loop that looks up environment for PATH.
730 2009-08-31 Eli Zaretskii <eliz@gnu.org>
732 * function.c (windows32_openpipe): Update envp after calling
733 sync_Path_environment.
735 2009-08-02 Paul Smith <psmith@gnu.org>
737 * remake.c (notice_finished_file): Ensure file->cmds is not null
738 before looping through them. Fixes Savannah bug #21824.
740 * doc/make.texi (Wildcard Examples): Clarify when objects is
741 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
742 (Include): Clarify the behavior of -include.
743 Fixes Savannah bug #18963.
745 2009-08-01 Paul Smith <psmith@gnu.org>
747 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
748 etc. come on the command line. Fixes Savannah bug #27093.
750 * expand.c (expand_argument): If the argument is large enough use
751 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
753 * variable.c (do_variable_definition): Avoid using alloca() to
754 hold values, which can be large. Fixes Savannah bug #23960.
756 * job.c (new_job): Use memmove() instead of strcpy() since both
757 pointers are in the same memory block. Fixes Savannah bug #27148.
758 Patch by Petr Machata.
760 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
762 * job.c (construct_command_argv_internal): Add "ulimit" and
763 "unset" to the sh_cmds for Unixy shells.
765 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
767 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
768 that set make_cv_sys_gnu_glob, so they are also correctly set
769 when the cache has been populated before.
771 2009-07-04 Eli Zaretskii <eliz@gnu.org>
773 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
774 exist, as realpath(3) does where it's supported.
776 2006-07-04 Eli Zaretskii <eliz@gnu.org>
778 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
779 (abspath): Support systems that define HAVE_DOS_PATHS (have
780 drive letters in their file names). Use IS_PATHSEP instead of a
781 literal '/' comparison. Fixes Savannah bug #26886.
783 2009-06-14 Paul Smith <psmith@gnu.org>
785 * remake.c (update_file_1): Remember the original file we marked
786 as updating, so we can clear that flag again. If we find a target
787 via vpath, FILE might change.
788 (check_dep): Ditto. Fixes Savannah bug #13529.
789 Patch by Reid Madsen <reid.madsen@tek.com>.
791 2009-06-13 Paul Smith <psmith@gnu.org>
793 * doc/make.texi (MAKEFILES Variable): Be explicit that files
794 included by MAKEFILES cannot give default goals.
795 * read.c (eval): If set_default is not set, pass the no-default-goal
796 value when we read included makefiles. Fixes Savannah bug #13401.
798 * ar.c (ar_name): Ensure that targets with empty parens aren't
799 considered archive member references: archive members must have a
800 non-empty "member" string. Fixes Savannah bug #18435.
802 * function.c (string_glob): Rely on multi_glob() to determine
803 whether files exist or not. Remove call to file_exists_p() which
804 is not always correct. Fixes Savannah bug #21231.
805 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
806 then only files that really exist will be returned.
807 * dep.h: Add new argument to multi_glob().
808 * rule.c (install_pattern_rule): Ditto.
809 * read.c (eval): Ditto.
810 * main.c (main): Ditto.
811 * implicit.c (pattern_search): Ditto.
812 * file.c (parse_prereqs): Ditto.
813 * default.c (set_default_suffixes): Ditto.
815 2009-06-09 Paul Smith <psmith@gnu.org>
817 * commands.c (set_file_variables): If always_make_flag is set,
818 always add the prereq to $?. Fixes Savannah bug #17825.
820 * remake.c (update_file_1): When rebuilding deps of FILE, also try
821 to rebuild the deps of all the also_make targets for that file.
822 Fixes Savannah bug #19108.
824 * implicit.c (pattern_search): Undo test for is_target, added by
825 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
826 Rule Search Algorithm". Fixes Savannah bug #17752.
828 * main.c (clean_jobserver): Clear the jobserver_fds options and
829 set job_slots to the default when we clean up.
830 (define_makeflags): Return the new MAKEFLAGS value.
831 (main): Reset MAKEFLAGS in the environment when we re-exec.
832 Fixes Savannah bug #18124.
834 2009-06-08 Paul Smith <psmith@gnu.org>
836 * read.c (eval): Collapse continuations post-semicolon on target-
837 specific variables. Fixes Savannah bug #17521.
839 2009-06-07 Paul Smith <psmith@gnu.org>
841 * job.c (reap_children): For older systems without waitpid() (are
842 there any of these left?) run wait(2) inside EINTRLOOP to handle
843 EINTR errors. Fixes Savannah bug #16401.
845 * (various): Debug message cleanup. Fixes Savannah bug #16469.
847 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
849 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
850 not the end, to catch second expansion $(eval ...) defining new
851 target/prereq relationships during snap_deps.
852 Fixes Savannah bug #24622.
854 * read.c (record_files): The second-expansion "f->updating" hack
855 was not completely correct: if assumed that the target with
856 commands always had prerequisites; if one didn't then the ordering
857 was messed up. Fixed for now to use f->updating to decide whether
858 to preserve the last element in the deps list... but this whole
859 area of constructing and reversing the deps list is too confusing
860 and needs to be reworked. Fixes Savannah bug #21198.
862 2009-06-06 Paul Smith <psmith@gnu.org>
864 * hash.c (hash_insert): Remove useless test for NULL.
865 Fixes Savannah bug #21823.
867 * make.h: Move SET_STACK_SIZE determination to make.h.
868 * main.c (main): New global variable, STACK_LIMIT, holds the
869 original stack limit when make was started.
870 * job.c (start_job_command): Reset the stack limit, if we changed it.
871 Fixes Savannah bug #22010.
873 * remake.c (check_dep): Only set the target's state to not-started
874 if it's not already running. Found this while testing -j10 builds
875 of glibc: various targets were being rebuilt multiple times.
876 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
879 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
880 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
883 2009-06-04 Paul Smith <psmith@gnu.org>
885 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
887 * maintMakefile: Modify access of config and gnulib Savannah
888 modules to use GIT instead of CVS.
890 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
891 Fixes Savannah bug #24655.
893 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
894 this can happen during some invocations of $(eval ...) for example.
895 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
897 2009-06-02 Paul Smith <psmith@gnu.org>
899 * configure.in: Check for fileno()
900 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
901 for the makefile file so invocations of $(shell ...) don't inherit it.
902 Fixes Savannah bug #24277.
904 2009-06-01 Paul Smith <psmith@gnu.org>
906 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
907 expansion was handled incorrectly. Rework the default goal
908 handling to save the variable only. Remove default_goal_file and
910 * read.c (eval): Check default_goal_var, not default_goal_name.
911 * read.c (record_target_var): Don't check default_goal_file here.
913 2009-05-31 Paul Smith <psmith@gnu.org>
915 * main.c (main): Expand the .DEFAULT_GOAL variable before using
916 it, and if the multi_glob() returns nothing (say it expanded to
917 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
919 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
920 $(and ..) to the reference. Fixes Savannah bug #25694.
922 * make.1: Be clear that some recipes will be executed even with -n.
923 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
925 * doc/make.texi (Override Directive): Make more clear how
926 overrides and appends interact.
927 Elucidates part of Savannah bug #26207.
929 * read.c (record_target_var): Don't reset the origin on
930 target-specific variables; try_variable_definition() will handle
931 this correctly. Fixes Savannah bug #26207.
933 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
934 Fixes Savannah bug #25712.
936 * implicit.c (pattern_search): Keep a pointer to the beginning of
937 the filename and save that instead of the constructed pointer.
938 Fixes Savannah bug #26593.
939 Patch by Mark Seaborn <mrs@mythic-beasts.com>
941 2009-05-30 Paul Smith <psmith@gnu.org>
943 * doc/make.texi (Multi-Line): Add a description of the new abilities
944 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
945 "command sequence" vs. "recipe" syntax.
946 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
947 after a define, to create variables with those flavors.
949 2009-05-25 Paul Smith <psmith@gnu.org>
951 Reworked the parser for variable assignments to allow multiple
952 modifiers, and in any order. Also allows variable and
953 prerequisites to be modifier names ('export', 'private', etc.)
955 * NEWS: Add notes about user-visible changes.
957 * read.c (struct vmodifiers): Remember what modifiers were seen.
958 (parse_var_assignment): New function to parse variable assignments.
959 (eval): Call the new function. Handle variable assignments earlier.
961 * variable.c (parse_variable_definition): Only parse; don't create var.
962 (assign_variable_definition): Call parse, then create the var.
964 2009-05-24 Paul Smith <psmith@gnu.org>
966 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
967 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
969 2009-03-14 Eli Zaretskii <eliz@gnu.org>
971 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
972 Fixes Savannah bug #25412.
974 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
975 prototype for xmalloc.
976 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
977 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
978 Loop over an array of extensions, instead of duplicating the same
979 code inline. Use SearchPath followed by CreateFile, instead of
980 the obsolete OpenFile. Fixes Savannah bug #17277.
981 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
982 to `find_file'. Fixes Savannah bug #25662.
984 2009-03-07 Eli Zaretskii <eliz@gnu.org>
986 * function.c (func_shell): Don't close pipedes[1] if it is -1.
987 Fixes Savannah bug #20495.
989 2009-02-28 Ralf Wildenhues <address@hidden>
991 * doc/make.texi (Instead of Execution): Document interaction of
992 -t with phony targets.
994 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
996 Introduce a new keyword "private" which applies to target-specific
997 variables and prevents their values from being inherited.
999 * variable.h (struct variable): Add private_var flag to each variable.
1000 Add a flag to specify which list entry switches to the parent target.
1001 * variable.c (define_variable_in_set): Initialize private_var flag.

1014 * make.h: Rename savestring to xstrndup.
1015 * commands.c (chop_commands): Ditto.
1016 * function.c (func_foreach): Ditto.
1017 * read.c (eval, record_files): Ditto.
1018 * variable.c (define_variable_in_set): Ditto.
1020 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1022 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1025 * w32/subproc/build.bat (GCCBuild): Likewise.
1027 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1029 * job.c (construct_command_argv_internal): Avoid extra backslash
1030 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1033 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1035 * README.W32.template: Remove obsolete text about non-support for
1036 -jN without Unixy shell. Remove obsolete text about not supplying
1037 Visual Studio project files (we do supply them). Modify text to
1038 prefer GCC builds to MSC builds.
1040 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1042 * doc/make.texi (Empty Targets): Fix typo.
1044 2008-03-27 Paul Smith <psmith@gnu.org>
1046 Fix Savannah bug #22379:
1047 * ar.c (ar_glob_match): Zero the allocated structure.
1048 * read.c (parse_file_seq): Ditto.
1050 2008-03-08 Brian Dessent <brian@dessent.net>
1052 * maintMakefile: Update Translation Project location.
1054 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1056 * variable.c (target_environment): Don't use shell_var if its
1057 `value' field is NULL.
1059 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1061 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1063 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1064 (TEXINFOS): Value changed to `doc/make.texi'.
1065 (.SUFFIXES): Use .texi instead of .texinfo.
1066 (make.info, make.dvi): Depend on doc/make.texi.
1067 (.texi.info): New target, instead of ".texinfo.info". Change -I
1068 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1069 (.texi): New target, instead of ".texinfo". Change -I switch to
1070 $(MAKEINFO) to look in doc/. Use --no-split.
1071 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I

1083 HAVE_DECL_SYS_SIGLIST.
1085 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1086 build does not use child_execute_job.
1088 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1089 export the SHELL environment variable to the child.

1113 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1115 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1116 a more complex value than a simple shell: if it's not a default
1117 shell now then expand it and see if is a default shell then.
1119 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1121 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1122 pathnames, with const strings.

1128 * make.h: Add a prototype for w32_kill() (change suggested by

1143 2007-09-11 Paul Smith <psmith@gnu.org>
1145 * doc/make.texi (Special Variables): Moved this into the "How to
1146 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1153 (Error Messages): Ditto.
1155 2007-09-10 Paul Smith <psmith@gnu.org>
1157 * commands.c (print_commands): Don't print an extra line in the
1158 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1160 * read.c (construct_include_path): Add the full string to the cache; we
1161 were chopping the last char.
1163 * NEWS: Announce the .RECIPEPREFIX special variable.
1164 * variable.c (lookup_special_var): Rename from handle_special_var().
1165 (lookup_variable): Call the new name.
1166 (set_special_var): New function: handle setting of special variables.
1167 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1170 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1171 * main.c (main): Create the .RECIPEPREFIX special variable.
1172 * read.c (eval): Remove the cmd_prefix characters from the command
1173 scripts here, so they're not stored in the commands array at all,
1174 rather than waiting and stripping them out during command construction.
1175 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1177 2007-08-15 Paul Smith <psmith@gnu.org>
1179 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1180 file has had the section info removed, so add some to make.texi
1181 before we include it.
1183 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1185 * remake.c (check_dep): Reset the target state for intermediate
1186 files. They might have been considered before but not updated

1203 * file.c (expand_deps): Use variable_buffer as the start of the
1204 buffer, not the original pointer (in case it was reallocated).
1205 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1206 Fixes Savannah bug #20452.

1243 Dave Korn <dave.korn@artimi.com>
1245 2007-05-08 Paul Smith <psmith@gnu.org>
1247 Fix Savannah bug #19656:
1249 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1251 * make.h: Change all case-insensitive string compares to use
1252 strcasecmp() (from POSIX). If we don't have that but do have one
1253 of the others, define strcasecmp to be one of those instead. If
1254 we don't have any, declare a prototype for our own version.
1256 * misc.c (strcasecmp): Use this if we can't find any native
1257 case-insensitive string comparison function.
1258 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1259 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1261 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1262 strcasecmp() instead of stricmp().
1263 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1264 instead of strcmpi().
1265 * acinclude.m4: Remove the strcasecmp() check from here.
1267 2007-03-21 Paul Smith <psmith@gnu.org>
1269 * configure.in: Don't turn on case-insensitive file system support
1270 if --disable-... is given. Fixes Savannah bug #19348.
1272 2007-03-19 Paul Smith <psmith@gnu.org>
1274 * ALL: Use the strcache for all file name strings, or other
1275 strings which we will never free. The goal is to save memory by
1276 avoiding duplicate copies of strings. However, at the moment this
1277 doesn't save much memory in most situations: due to secondary
1278 expansion we actually save prerequisite lists twice (once before
1279 the secondary expansion, and then again after it's been parsed
1280 into individual file names in the dep list). We will resolve this
1281 in a future change, by doing the parsing up-front for targets
1282 where secondary expansion is not set.
1284 Moving things into the strcache also allows us to use const
1285 pointers in many more places.
1287 2007-01-03 Paul Smith <psmith@gnu.org>
1289 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1290 the function, not just the first. Fixes Savannah bug #18680.
1292 2006-11-18 Paul Smith <psmith@gnu.org>
1294 * strcache.c (strcache_add_len): Don't allocate a new buffer
1295 unless the string is not already nil-terminated. Technically this
1296 is a violation of the standard, since we may be passed an array
1297 that is not long enough to test one past. However, in make this
1298 is never true since we only use nil-terminated strings or
1299 sub-strings thereof.
1301 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1303 * main.c: New global cmd_prefix, defaults to '\t'.
1304 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1307 * dir.c: Constified.
1308 (dir_contents_file_exists_p): Check for an error return from
1309 readdir(), just in case.
1311 * commands.c: Constified.
1312 * default.c: Constified.
1313 * expand.c: Constified.
1314 * function.c: Partial constification.

1319 * w32/pathstuff.c: Partial constification.
1321 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1323 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1324 backslashes and drive letters as absolute.
1326 2006-10-22 Paul Smith <psmith@gnu.org>
1328 * main.c (struct command_switch): Use const and void*.
1330 2006-10-21 Paul Smith <psmith@gnu.org>
1333 * arscan.c: Constified.
1335 2006-09-30 Paul Smith <psmith@gnu.org>
1337 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1338 point to lastword since the example was updated.
1339 Fixes Savannah bug #16304.
1340 (Secondary Expansion): Correct example description.
1341 Fixes Savannah bug #16468.
1342 (Makefile Contents): Clarify that comments cannot appear within
1343 variable references or function calls.
1344 Fixes Savannah bug #16577.
1345 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1346 Fixes Savannah bug #17701.
1347 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1349 prerequisites. Fixes Savannah bug #17880.
1350 (Rule Syntax): "lise" -> "list"
1351 (Multiple Rules): ... -> @dots{}
1352 (Splitting Lines): ditto.
1354 * remake.c (update_file_1): Prereqs that don't exist should be
1355 considered changed, for the purposes of $?.
1356 Fixes Savannah bug #16051.
1358 * make.1: Remove extraneous "+".
1359 Fixes Savannah bug #16652.

1397 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1398 that don't have extended grep.
1399 (cvsclean): Use $(PERL) instead of perl.
1401 2006-04-09 Paul D. Smith <psmith@gnu.org>
1403 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1405 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1406 inner-scope variables don't mask outer-scope variables.

1411 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1412 values from memory allocation functions: they return void* and so
1413 don't need to be cast. Also remove (char *) casts of arguments to

1428 2006-04-06 Paul D. Smith <psmith@gnu.org>
1430 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we

1469 2006-03-23 Paul D. Smith <psmith@gnu.org>

1474 * Makefile.am: Make sure to clean up build.sh during distclean.
1475 Fixes Savannah bug #16166.
1477 * misc.c (log_access): Takes a const char *.

1493 make sure I don't forget any).
1495 * main.c (clean_jobserver): Move jobserver cleanup code into a new

1512 (copy_dep_chain): Copy stem.
1513 (free_dep_chain): Use free_dep.
1514 * read.c (record_files): Store stem in the dependency line.

1528 (allocated_variable_append): Don't expand the final result.
1529 Fixes Savannah bug #15913.
1531 2006-03-09 Paul Smith <psmith@gnu.org>
1533 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1534 listed non-existent files as changed. Turns out there's a bug in
1535 the Linux kernel builds which means that this change causes
1536 everything to rebuild every time. We will re-introduce this fix
1537 in the next release, to give them time to fix their build system.
1538 Fixes Savannah bug #16002.

1559 string values to avoid memory leaks.
1561 * expand.c (recursively_expand_for_file): Only set reading_file to
1562 an initialized value.
1564 * implicit.c (pattern_search): We need to make a copy of the stem

1576 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1577 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1578 the calls to _beginthreadex.
1580 * expand.c (recursively_expand_for_file): Initialize `save' to
1581 prevent compiler warnings.

1600 Fix for Savannah bug #106.
1602 * expand.c (expanding_var): Keep track of which variable we're
1603 expanding. If no variable is being expanded, it's the same as
1605 * make.h (expanding_var): Declare it.
1606 * expand.c (recursively_expand_for_file): Set expanding_var to the
1607 current variable we're expanding, unless there's no file info in
1608 it (could happen if it comes from the command line or a default
1609 variable). Restore it before we exit.
1610 * expand.c (variable_expand_string): Use the expanding_var file
1611 info instead of the reading_file info.
1612 * function.c (check_numeric): Ditto.
1614 (func_wordlist): Ditto.
1615 (func_error): Ditto.
1616 (expand_builtin_function): Ditto.
1617 (handle_function): Ditto.
1619 2006-02-14 Paul D. Smith <psmith@gnu.org>
1621 * read.c (eval): Even if the included filenames expands to the
1622 empty string we still need to free the allocated buffer.
1624 * implicit.c (pattern_search): If we allocated a variable set for
1625 an impossible file, free it.
1626 * variable.c (free_variable_set): New function.
1627 * variable.h: Declare it.
1629 * read.c (read_all_makefiles): Makefile names are kept in the
1630 strcache, so there's never any need to alloc/free them.
1633 * main.c (main): Add "archives" to the .FEATURES variable if
1634 archive support is enabled.
1635 * doc/make.texi (Special Variables): Document it.
1637 2006-02-13 Paul D. Smith <psmith@gnu.org>
1639 * implicit.c (pattern_search): Add checking for DOS pathnames to
1640 the pattern rule target LASTSLASH manipulation.
1641 Fixes Savannah bug #11183.

1645 * (ALL FILES): Updated copyright and license notices.
1647 2006-02-10 Paul D. Smith <psmith@gnu.org>
1649 A new internal capability: the string cache is a read-only cache
1650 of strings, with a hash table interface for fast lookup. Nothing
1651 in the cache will ever be freed, so there's no need for reference
1652 counting, etc. This is the beginning of a full solution for
1653 Savannah bug #15182, but for now we only store makefile names here.
1655 * strcache.c: New file. Implement a read-only string cache.
1656 * make.h: Add prototypes for new functions.
1657 * main.c (initialize_global_hash_tables): Initialize the string cache.
1658 (print_data_base): Print string cache stats.
1659 * read.c (eval_makefile): Use the string cache to store makefile
1660 names. Rewrite the string allocation to be sure we free everything.
1662 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1664 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1665 directory time stamp didn't change, except on FAT filesystems.
1666 Suggested by J. David Bryan <jdbryan@acm.org>.
1668 2006-02-09 Paul D. Smith <psmith@gnu.org>
1670 * function.c (func_or): Implement a short-circuiting OR function.
1671 (func_and): Implement a short-circuiting AND function.
1672 (function_table_init): Update the table with the new functions.
1673 * doc/make.texi (Conditional Functions): Changed the "if" section
1674 to one on general conditional functions. Added documentation for
1675 $(and ...) and $(or ...) functions.
1676 * NEWS: Note new $(and ...) and $(or ...) functions.
1678 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1680 * job.h (struct child): Add the dontcare bitfield.
1681 * job.c (new_job): Cache dontcare flag.
1682 * job.c (reap_children): Use cached dontcare flag instead of the
1683 one in struct file. Fixes Savannah bug #15641.
1685 2006-02-06 Paul D. Smith <psmith@gnu.org>
1687 * vpath.c (selective_vpath_search): If the file we find has a
1688 timestamp from -o or -W, use that instead of the real time.
1689 * remake.c (f_mtime): If the mtime is a special token from -o or
1690 -W, don't overwrite it with the real mtime.
1691 Fixes Savannah bug #15341.
1693 Updates from Markus Mauhart <qwe123@chello.at>:
1695 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1708 Fixes Savannah bug #15533.
1709 * filedef.h (struct file): Add a new LAST pointer.
1711 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1712 the comparison. For 64-bits systems the result of the subtraction
1713 might not fit into an int. Use comparison instead.
1714 Fixes Savannah bug #15534.
1716 * doc/make.texi: Update the chapter on writing commands to reflect
1717 the changes made in 3.81 for backslash/newline and SHELL handling.

1737 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1739 * remake.c (update_goal_chain): Set g->changed instead of
1740 incrementing it, as it is only 8-bit wide, and could overflow if
1741 many commands got started in update_file.
1743 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1745 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1746 MAXIMUM_WAIT_OBJECTS.
1747 (process_wait_for_any_private): Change dimension of handles[]
1748 array to MAXIMUM_WAIT_OBJECTS.

1750 (process_register): Don't register more processes than the
1751 available number of slots.
1752 (process_easy): Don't start new processes if all slots are used up.
1754 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1755 are already more children than sub_proc.c can handle, behave as if
1756 the load were too high.
1757 (start_job_command): Fix a typo in error message when process_easy
1760 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1762 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1763 the shell is not sh.exe.
1765 * job.c (create_batch_file): Renamed from create_batch_filename;
1766 all callers changed. Don't close the temporary file; return its
1767 file descriptor instead. New arg FD allows to return the file
1769 (construct_command_argv_internal): Use _fdopen instead of fopen to
1770 open the batch file.
1772 2006-01-04 Paul D. Smith <psmith@gnu.org>
1774 * readme.vms: Updates for case-insensitive VMS file systems from
1775 Hartmut Becker <Hartmut.Becker@hp.com>.

1795 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1796 disable warnings for MSC.
1797 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1799 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1801 * doc/make.texi (Execution): Add a footnote about changes in
1802 handling of backslash-newline sequences. Mention the differences
1803 on MS-DOS and MS-Windows.
1805 * NEWS: More details about building the MinGW port and a pointer
1806 to README.W32. Fix the section name that describes the new
1807 backward-incompatible processing of backslash-newline sequences.
1808 The special processing of SHELL set to "cmd" is only relevant to
1809 MS-Windows, not MS-DOS.
1811 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1813 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1814 to DWORD, to avoid compiler warnings.
1815 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1816 use %ld in format, to avoid compiler warnings.

1830 * read.c (record_target_var): Initialize variable's export field
1831 with v_default instead of leaving it "initialized" by whatever
1832 garbage happened to be on the heap.

1836 * make.1: Fix some display errors and document all existing options.
1837 Patch by Mike Frysinger <vapier@gentoo.org>.
1839 2005-12-11 Paul D. Smith <psmith@gnu.org>
1841 * implicit.c (pattern_search): If 2nd expansion is not set for
1842 this implicit rule, replace the pattern with the stem directly,
1843 and don't re-expand the variable list. Along with the other
1844 .SECONDEXPANSION changes below, fixes bug #13781.
1846 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1848 * implicit.c (pattern_search): Mark other files that this rule
1849 builds as targets so that they are not treated as intermediates
1850 by the pattern rule search algorithm. Fixes bug #13022.
1852 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1854 * remake.c (notice_finished_file): Propagate the change of
1855 modification time to all the double-colon entries only if

1874 * read.c (record_files): Don't set deps flags if there are no deps.
1875 * maintMakefile: We only need to build the templates when we are
1876 creating a distribution, so don't do it for "all".
1878 2005-10-24 Paul D. Smith <psmith@gnu.org>
1880 Make secondary expansion optional: its enabled by declaring the
1881 special target .SECONDEXPANSION.
1883 * NEWS: Update information on second expansion capabilities.
1884 * doc/make.texi (Secondary Expansion): Document the
1885 .SECONDEXPANSION special target and its behavior.

1887 prerequisite list was found in a static pattern rule.
1888 (free_dep_chain): Declare a prototype.
1889 * file.c (parse_prereqs): New function: break out some complexity
1891 (expand_deps): If we aren't doing second expansion, replace % with
1892 the stem for static pattern rules. Call the new function.
1893 * filedef.h (parse_prereqs): Declare a prototype.
1894 * implicit.c (pattern_search): Initialize the new staticpattern
1896 * main.c (second_expansion): Declare a global variable to remember
1897 if the special target has been seen. Initialize the new
1898 staticpattern field for prerequisites.
1899 * make.h: Extern for second_expansion.
1900 * misc.c (free_dep_chain): New function: frees a struct dep list.
1901 * read.c (read_all_makefiles): Initialize the staticpattern field.

1903 (record_files): Check for the .SECONDEXPANSION target and set
1904 second_expansion global if it's found.
1905 Use the new free_dep_chain() instead of doing it by hand.
1906 Set the staticpattern field for prereqs of static pattern targets.
1908 2005-10-16 Paul D. Smith <psmith@gnu.org>
1910 * main.c (main): Set CURDIR to be a file variable instead of a
1911 default, so that values of CURDIR inherited from the environment
1912 won't override the make value.
1914 2005-09-26 Paul D. Smith <psmith@gnu.org>
1916 * job.c (construct_command_argv_internal): If the line is empty
1917 remember to free the temporary argv strings.
1920 2005-09-16 Paul D. Smith <psmith@gnu.org>
1922 * job.c (start_job_command): The noerror flag is a boolean (single
1923 bit); set it appropriately.
1924 Reported by Mark Eichin <eichin@metacarta.com>
1926 2005-08-29 Paul D. Smith <psmith@gnu.org>
1928 * function.c (func_error): On Windows, output from $(info ...)
1929 seems to come in the wrong order. Try to force it with fflush().
1931 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1933 * read.c (record_files): Move code that sets stem for static
1934 pattern rules out of the if (!two_colon) condition so it is
1935 also executed for two-colon rules. Fixes Savannah bug #13881.
1937 2005-08-08 Paul D. Smith <psmith@gnu.org>
1939 * make.h: Don't test that __STDC__ is non-0. Some compilers
1940 (Windows for example) set it to 0 to denote "ISO C + extensions".
1943 2005-08-07 Paul D. Smith <psmith@gnu.org>
1945 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1946 conditional (slightly different version of a fix from Eli).
1948 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1949 If make is running in parallel without -k and two jobs die in a
1950 row, but not too close to each other, then make will quit without
1951 waiting for the rest of the jobs to die.
1953 * main.c (die): Don't reset err before calling reap_children() the
1954 second time: we still want it to be in the error condition.
1955 * job.c (reap_children): Use a static variable, rather than err,
1956 to control whether or not the error message should be printed.
1958 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1960 * w32/subproc/sub_proc.c: Include signal.h.
1961 (process_pipe_io, process_file_io): Pass a pointer to a local
1962 DWORD variable to GetExitCodeProcess. If the exit code is
1963 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1965 * job.c [WINDOWS32]: Include windows.h.
1966 (main_thread) [WINDOWS32]: New global variable.
1967 (reap_children) [WINDOWS32]: Get the handle for the main thread

1970 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1971 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1972 doing anything else. When we are done, close the main thread
1973 handle and exit with status 130.
1975 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1977 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1980 * main.c (find_and_set_default_shell): If found a DOSish shell,
1981 set sh_found and the value of default_shell, and report the
1982 findings in debug mode.
1984 * job.c (construct_command_argv_internal): Check unixy_shell, not
1985 no_default_sh_exe, to decide whether to use Unixy or DOSish
1988 * README.W32: Update with info about the MinGW build.
1990 * build_w32.bat: Support MinGW.
1992 * w32/subproc/build.bat: Likewise.
1994 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1995 printing DWORD args.
1997 * function.c (windows32_openpipe): Fix format strings for printing
2000 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2002 (start_job_command): Fix format string for printing the result of
2004 (start_job_command) [WINDOWS32]: Do not define.
2005 (exec_command): Fix format string for printing HANDLE args.
2007 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2008 to avoid compiler warnings.
2009 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2010 (Note: some of these fixes were submitted independently by J. Grant)

2018 2005-07-15 Paul Smith <psmith@gnu.org>
2020 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2021 we don't have a POSIX shell, then revert to the old
2022 backslash-newline behavior (where they are stripped).
2025 2005-07-08 Paul D. Smith <psmith@gnu.org>
2027 * config.h.W32.template: Reorder to match the standard config.h,
2028 for easier comparisons.
2029 From J. Grant <jg@jguk.org>
2031 * maintMakefile: Remove .dep_segment before overwriting it, in
2032 case it's not writable or noclobber is set.
2033 * expand.c (variable_expand_string): Cast result of pointer
2034 arithmetic to avoid a warning.
2035 * main.c (switches): Add full-fledged final initializer.
2037 2005-07-06 Paul D. Smith <psmith@gnu.org>
2039 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2040 * signame.c (strsignal): If we found _sys_siglist[] or
2041 __sys_siglist[] use those instead of sys_siglist[].
2042 From Albert Chin <china@thewrittenword.com>
2044 2005-07-04 Paul D. Smith <psmith@gnu.org>
2046 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2047 globfree(); set up to use the GNU versions.
2048 From Martin Zinser <zinser@zinser.no-ip.info>
2050 2005-07-03 Paul D. Smith <psmith@gnu.org>
2052 From J. Grant <jg@jguk.org>:

2060 2005-06-28 Paul D. Smith <psmith@gnu.org>
2062 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2063 declaration was checked but not present.
2065 2005-06-27 Paul D. Smith <psmith@gnu.org>
2067 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2068 to unsigned long. Fixes Savannah bug #13550.
2070 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2071 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.

2074 2005-06-26 Paul D. Smith <psmith@gnu.org>
2076 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2077 it if ANSI_STRING is not set.
2079 2005-06-25 Paul D. Smith <psmith@gnu.org>
2081 * read.c (eval): If no filenames are passed to any of the
2082 "include" variants, don't print an error.
2083 * doc/make.texi (Include): Document this.
2084 Fixes Savannah bug #1761.
2086 * job.c (construct_command_argv_internal): Sanitize handling of
2087 backslash/newline pairs according to POSIX: that is, keep the
2088 backslash-newline in the command script, but remove a following
2089 TAB character, if present. In the fast path, make sure that the
2090 behavior matches what the shell would do both inside and outside
2091 of quotes. In the slow path, quote the backslash and put a
2092 literal newline in the string.
2093 Fixes Savannah bug #1332.
2094 * doc/make.texi (Execution): Document the new behavior and give
2096 * NEWS: Make a note of the new behavior.
2098 * make.h [WINDOWS32]: #include <direct.h>.
2099 Fixes Savannah bug #13478.
2101 * remake.c (name_mtime): If the stat() of a file fails and the -L
2102 option was given and the file is a symlink, take the best mtime of
2103 the symlink we can get as the mtime of the file and don't fail.
2104 Fixes Savannah bug #13280.
2106 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2107 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2108 inside a variable reference. Make this function static as it's
2110 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2111 parsing an unexpanded line looking for semicolons.
2112 Fixes Savannah bug #1454.
2113 * misc.c (remove_comments): Move this to read.c and make it static
2114 as it's only used there. Call find_char_unquote() with new arg.
2115 * make.h: Remove prototypes for find_char_unquote() and
2116 remove_comments() since they're static now.
2118 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2119 its export flag and obtain its value. When we need to re-exec,
2120 increment the value and add it into the environment.
2121 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2122 * NEWS: Mention MAKE_RESTARTS.
2123 * main.c (always_make_set): New variable. Change the -B option to
2124 set this one instead.
2125 (main): When checking makefiles, only set always_make_flag if
2126 always_make_set is set AND the restarts flag is 0. When building
2127 normal targets, set it IFF always_make_set is set.
2128 (main): Avoid infinite recursion with -W, too: only set what-if
2129 files to NEW before we check makefiles if we've never restarted
2130 before. If we have restarted, set what-if files to NEW _after_ we
2132 Fixes Savannah bug #7566:
2134 2005-06-17 Paul D. Smith <psmith@gnu.org>
2136 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2137 in the prerequisites list.
2139 2005-06-12 Paul D. Smith <psmith@gnu.org>
2141 Fix Savannah bug # 1328.
2143 * configure.in: Check for atexit().
2144 * misc.c (close_stdout): Test stdout to see if writes to it have
2145 failed. If so, be sure to exit with a non-0 error code. Based on
2146 code found in gnulib.
2147 * make.h: Prototype.
2148 * main.c (main): Install close_stdout() with atexit().
2150 2005-06-10 Paul D. Smith <psmith@gnu.org>
2152 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2154 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2155 headers; make vmsWaitForChildren() static; extern vmsify().
2156 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2157 Don't create child_execute_job() here (it's in vmsjobs.c).
2158 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2160 2005-06-09 Paul D. Smith <psmith@gnu.org>
2162 * variable.c (push_new_variable_scope): File variables point
2163 directly to the global_setlist variable. So, inserting a new
2164 scope in front of that has no effect on those variables: they
2165 don't go through current_variable_set_list. If we're pushing a
2166 scope and the current scope is global, push it "the other way" so
2167 that the new setlist is in the global_setlist variable, and
2168 next points to a new setlist with the global variable set.
2169 (pop_variable_scope): Properly undo a push with the new
2171 Fixes Savannah bug #11913.
2173 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2175 * job.c (reap_children): Don't die of the command failed but
2176 the dontcare flag is set. Fixes Savannah bug #13216.
2178 * implicit.c (pattern_search): When creating a target from
2179 an implicit rule match, lookup pattern target and set precious
2180 flag in a newly created target. Fixes Savannah bug #13218.
2182 2005-05-13 Paul D. Smith <psmith@gnu.org>
2184 Implement "if... else if... endif" syntax.
2186 * read.c (eval): Push all checks for conditional words ("ifeq",
2187 "else", etc.) down into the conditional_line() function.
2188 (conditional_line): Rework to allow "else if..." clause. New
2189 return value -2 for lines which are not conditionals. The
2190 ignoring flag can now also be 2, which means "already parsed a
2191 true branch". If that value is seen no other branch of this
2192 conditional can be considered true. In the else parsing if there
2193 is extra text after the else, invoke conditional_line()
2194 recursively to see if it's another conditional. If not, it's an
2195 error. If so, raise the conditional value to this level instead
2196 of creating a new conditional nesting level. Special check for
2197 "else" and "endif", which aren't allowed on the "else" line.
2198 * doc/make.texi (Conditional Syntax): Document the new syntax.
2200 2005-05-09 Paul D. Smith <psmith@gnu.org>
2202 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2203 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2204 recurses to the w32 directory, even on non-Windows systems. Use
2205 the method suggested in the automake manual.
2206 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2207 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2209 2005-05-07 Paul D. Smith <psmith@gnu.org>
2211 * main.c (die): If we're dying with a fatal error (not that a
2212 command has failed), write back any leftover tokens before we go.
2214 * job.c (set_child_handler_action_flags): If there are jobs
2215 waiting for the load to go down, set an alarm to go off in 1
2216 second. This allows us to wake up from a potentially long-lasting
2217 read() and start a new job if the load has gone down. Turn it off
2219 (job_noop): Dummy signal handler function.
2220 (new_job): Invoke it with the new semantics.
2222 * docs/make.texi: Document secondary expansion. Various cleanups
2225 2005-05-03 Paul D. Smith <psmith@gnu.org>
2227 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2228 the targets which are to ultimately be made are called "goals";
2229 see the GNU make manual. Also, MAKECMDGOALS, etc.
2231 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2232 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2233 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2235 2005-05-02 Paul D. Smith <psmith@gnu.org>
2237 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2238 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2239 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2240 functions to vmsjobs.c. #include it into jobs.c.
2242 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2243 jobserver tokens. I found that this happens when an exported
2244 recursive variable contains a $(shell ...) function reference: in
2245 this situation we could "forget" to write back a token.
2247 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2248 we have. It's not reliable to depend on the number of children in
2249 our linked list so keep a separate count.
2250 (new_job): Check jobserver_tokens rather than children &&
2251 waiting_jobs. Increment jobserver_tokens when we get one.
2252 (free_child): If jobserver_tokens is 0, internal error. If it's
2253 >1, write a token back to the jobserver pipe (we don't write a
2254 token for the "free" job). Decrement jobserver_tokens.
2256 * main.c: Add variable master_job_slots.
2257 (main): Set it to hold the number of jobs requested if we're the
2258 master process, when using the jobserver.
2259 (die): Sanity checks: first test jobserver_tokens to make sure
2260 this process isn't holding any tokens we didn't write back.
2261 Second, if master_job_slots is set count the tokens left in the
2262 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2264 2005-04-24 Paul D. Smith <psmith@gnu.org>
2266 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2267 with -l# can lose jobserver tokens, because waiting jobs are not
2268 consulted properly when checking for the "free" token.
2270 * job.c (free_child): Count waiting_jobs as having tokens.
2271 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2272 handle jobs waiting for the load to drop.
2274 2005-04-23 Paul D. Smith <psmith@gnu.org>
2276 * main.c (main): Be careful to not core if a variable setting in
2277 the environment doesn't contain an '='. This is illegal but can
2278 happen in broken setups.
2279 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2281 2005-04-12 Paul D. Smith <psmith@gnu.org>
2283 The second expansion feature causes significant slowdown. Timing
2284 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2285 read the makefile before the feature, to 11+s to do the same
2286 operations after the feature. Additionally, memory usage
2287 increased drastically. To fix this I added some intelligence that
2288 avoids the overhead of the second expansion unless it's required.
2290 * dep.h: Add a new boolean field, need_2nd_expansion.
2292 * read.c (eval): When creating the struct dep for the target,
2293 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2294 (record_files): If there's a "%" in a static pattern rule, it gets
2295 converted to "$*" so set need_2nd_expansion to 1.
2297 * file.c (expand_deps): Rework to be more efficient. Only perform
2298 initialize_file_variables(), set_file_variables(), and
2299 variable_expand_for_file() if the need_2nd_expansion is set.
2301 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2302 (pattern_search): Ditto.
2303 * main.c (handle_non_switch_argument): Ditto.
2305 * read.c (read_all_makefiles): Ditto.
2306 (eval_makefile): Ditto.
2308 2005-04-07 Paul D. Smith <psmith@gnu.org>
2310 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2311 * variable.c (sync_Path_environment): Ditto.
2312 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2314 * main.c (main): Define the .FEATURES variable.
2315 * NEWS: Announce .FEATURES.
2316 * doc/make.texi (Special Variables): Document .FEATURES.
2318 * remake.c (check_dep): If a file is .PHONY, update it even if
2319 it's marked intermediate. Fixes Savannah bug #12331.
2321 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2323 * file.c (expand_deps): Factor out the second expansion and
2324 prerequisite line parsing logic from snap_deps().
2326 * file.c (snap_deps): Use expand_deps(). Expand and parse
2327 prerequisites of the .SUFFIXES special target first. Fixes
2328 Savannah bug #12320.
2330 2005-03-13 Paul D. Smith <psmith@gnu.org>
2332 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2335 2005-03-11 Paul D. Smith <psmith@gnu.org>
2337 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2338 available, not undefined (from Earnie Boyd).
2340 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2342 * implicit.c (pattern_search): Mark an intermediate target as
2343 precious if it happened to be a prerequisite of some (other)
2344 target. Fixes Savannah bug #12267.
2346 2005-03-09 Paul D. Smith <psmith@gnu.org>
2348 * read.c (eval_makefile): Add alloca(0).
2349 (eval_buffer): Ditto.
2351 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2353 * main.c (main): Use o_file instead of o_default when defining
2354 the .DEFAULT_TARGET special variable.
2355 * read.c (eval): Use define_variable_global() instead of
2356 define_variable() when setting new value for the .DEFAULT_TARGET
2357 special variable. Fixes Savannah bug #12266.
2359 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2361 * imlicit.c (pattern_search): Mark files for which an implicit
2362 rule has been found as targets. Fixes Savannah bug #12202.
2364 2005-03-04 Paul D. Smith <psmith@gnu.org>
2367 * doc/make.texi (Automatic Variables): Document $|.
2369 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2371 * read.c (record_files): Instead of substituting % with
2372 actual stem value in dependency list replace it with $*.
2373 This fixes stem triple expansion bug.
2375 * implicit.c (pattern_search): Copy stem to a separate
2376 buffer and make it a properly terminated string. Assign
2377 this buffer instead of STEM (which is not terminated) to
2378 f->stem. Instead of substituting % with actual stem value
2379 in dependency list replace it with $*. This fixes stem
2380 triple expansion bug.
2382 2005-03-01 Paul D. Smith <psmith@gnu.org>
2384 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2385 on Windows, as it takes a handle not a pid. Just exit.
2386 Fix from patch #3679, provided by Alessandro Vesely.
2388 * configure.in: Update check for sys_siglist[] from autoconf manual.
2389 * signame.c (strsignal): Update to use the new autoconf macro.
2391 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2393 * read.c (record_files): Add a check for the list of prerequisites
2394 of a static pattern rule being empty. Fixes Savannah bug #12180.
2396 2005-02-28 Paul D. Smith <psmith@gnu.org>
2398 * doc/make.texi (Text Functions): Update docs to allow the end
2399 ordinal for $(wordlist ...) to be 0.
2400 * function.c (func_wordlist): Fail if the start ordinal for
2401 $(wordlist ...) is <1. Matches documentation.
2402 Resolves Savannah support request #103195.
2404 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2405 previously we were stopping when !-q, exactly the opposite. This
2406 has been wrong since version 1.34, in 1994!
2407 (update_file): If we got an error don't break out to run more
2408 double-colon rules: just return immediately.
2409 Fixes Savannah bug #7144.
2411 2005-02-27 Paul D. Smith <psmith@gnu.org>
2413 * misc.c (end_of_token): Make argument const.
2414 * make.h: Update prototype.
2416 * function.c (abspath, func_realpath, func_abspath): Use
2417 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2418 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2419 * read.c (record_files): Ditto.
2420 * variable.c (do_variable_definition): Ditto.
2422 * function.c (func_error): Create a new function $(info ...) that
2423 simply prints the message to stdout with no extras.
2424 (function_table_init): Add new function to the table.
2425 * NEWS: Add $(info ...) reference.
2426 * doc/make.texi (Make Control Functions): Document it.
2428 New feature: if the system supports symbolic links, and the user
2429 provides the -L/--check-symlink-time flag, then use the latest
2430 mtime between the symlink(s) and the target file.
2432 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2433 readlink(). If both are available, define MAKE_SYMLINKS.
2434 * main.c: New variable: check_symlink_flag.
2435 (usage): Add a line for -L/--check-symlink-times to the help string.
2436 (switches): Add -L/--check-symlink-times command line argument.
2437 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2438 print a warning and disable it again.
2439 * make.h: Declare check_symlink_flag.
2440 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2441 if the file is a symlink then check each link in the chain and
2442 choose the NEWEST mtime we find as the mtime for the file. The
2443 newest mtime might be the file itself!
2444 * NEWS: Add information about this new feature.
2445 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2447 Avoid core dumps described in Savannah bug # 12124:
2449 * file.c: New variable snapped_deps remember whether we've run
2451 (snap_deps): Set it.
2452 * filedef.h: Extern it.
2453 * read.c (record_files): Check snapped_deps; if it's set then
2454 we're trying to eval a new target/prerequisite relationship from
2455 within a command script, which we don't support. Fatal.
2457 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2459 Implementation of the .DEFAULT_TARGET special variable.
2461 * read.c (eval): If necessary, update default_target_name when
2463 * read.c (record_files): Update default_target_file if
2464 default_target_name has changed.
2465 * main.c (default_target_name): Define.
2466 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2467 default_target_name is set use default_target_file as a root
2469 * filedef.h (default_target_name): Declare.
2470 * dep.h (free_dep_chain):
2471 * misc.c (free_dep_chain): Change to operate on struct nameseq
2472 and change name to free_ns_chain.
2473 * file.c (snap_deps): Update to use free_ns_chain.
2475 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2477 Implementation of the second expansion in explicit rules,
2478 static pattern rules and implicit rules.
2480 * read.c (eval): Refrain from chopping up rule's dependencies.
2481 Store them in a struct dep as a single dependency line. Remove
2482 the code that implements SySV-style automatic variables.
2484 * read.c (record_files): Adjust the code that handles static
2485 pattern rules to expand all percents instead of only the first
2486 one. Reverse the order in which dependencies are stored so that
2487 when the second expansion reverses them again they appear in
2488 the makefile order (with some exceptions, see comments in
2489 the code). Remove the code that implements SySV-style automatic
2492 * file.c (snap_deps): Implement the second expansion and chopping
2493 of dependency lines for explicit rules.
2495 * implicit.c (struct idep): Define an auxiliary data type to hold
2496 implicit rule's dependencies after stem substitution and
2499 * implicit.c (free_idep_chain): Implement.
2501 * implicit.c (get_next_word): Implement helper function for
2502 parsing implicit rule's dependency lines into words taking
2503 into account variable expansion requests. Used in the stem
2506 * implicit.c (pattern_search): Implement the second expansion
2507 for implicit rules. Also fixes bug #12091.
2509 * commands.h (set_file_variables): Declare.
2510 * commands.c (set_file_variables): Remove static specifier.
2512 * dep.h (free_dep_chain): Declare.
2513 * misc.c (free_dep_chain): Implement.
2515 * variable.h (variable_expand_for_file): Declare.
2516 * expand.c (variable_expand_for_file): Remove static specifier.
2518 * make.h (strip_whitespace): Declare.
2519 * function.c (strip_whitespace): Remove static specifier.
2521 2005-02-26 Paul D. Smith <psmith@gnu.org>
2523 * main.c (main): Check for ferror() when reading makefiles from stdin.
2524 Apparently some shells in Windows don't close pipes properly and
2527 2005-02-24 Jonathan Grant <jg@jguk.org>
2529 * configure.in: Add MinGW configuration options, and extra w32 code
2531 * Makefile.am: Add MinGW configuration options, and extra w32 code
2533 * main.c: Determine correct program string (after last \ without .exe).
2534 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2536 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2537 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2538 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2539 environment support.
2541 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2543 * function.c (func_shell): When initializing error_prefix, check
2544 that reading file name is not null. This fixes long-standing
2545 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2547 2005-02-09 Paul D. Smith <psmith@gnu.org>
2549 * maintMakefile: Update the CVS download URL to simplify them.
2550 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2551 downloading the .texi files from Savannah now.
2553 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2555 * main.c (handle_non_switch_argument): Only add variables to
2556 command_variables if they're not already there: duplicate settings
2557 waste space and can be confusing to read.
2559 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2560 this header is never included by non-WINDOWS32 code, and it
2561 requires <config.h> to define which isn't always included first.
2563 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2564 testing MINGW32 versions.
2566 * main.c (log_working_directory): flush stdout to be sure the WD
2567 change is printed before any stderr messages show up.
2569 2005-02-01 Paul D. Smith <psmith@gnu.org>
2571 * maintMakefile (po_repo): Update the GNU translation site URL.
2573 2004-12-01 Paul D. Smith <psmith@gnu.org>
2575 * main.c (main): Change char* env_shell to struct variable shell_var.
2576 * variable.c (target_environment): Use new shell_var.
2578 2004-11-30 Paul D. Smith <psmith@gnu.org>
2580 * configure.in: The old way we avoided creating build.sh from
2581 build.sh.in before build.sh.in exists doesn't work anymore; we
2582 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2583 the help!). This also keeps automake from complaining.
2584 * Makefile.am (README): Add a dummy target so automake won't
2585 complain that this file doesn't exist when we checkout from CVS.
2586 * maintMakefile (.dep_segment): Rewrite this rule since newer
2587 versions of automake don't provide DEP_FILES.
2589 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2591 Implementation of `realpath' and `abspath' built-in functions.
2593 * configure.in: Check for realpath.
2594 * function.c (abspath): Return an absolute file name that does
2595 not contain any `.' or `..' components, nor repeated `/'.
2596 * function.c (func_abspath): For each name call abspath.
2597 * function.c (func_realpath): For each name call realpath
2598 from libc or delegate to abspath if realpath is not available.
2599 * doc/make.texi (Functions for File Names): Document new functions.
2600 * doc/make.texi (Quick Reference): Ditto.
2602 2004-11-28 Paul D. Smith <psmith@gnu.org>
2604 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2605 arguments. Fixes bug #10252.
2607 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2609 * main.c (main): Set SHELL to v_noexport by default. Remember the
2610 original environment setting of SHELL in the env_shell variable.
2611 * main.h: Export new env_shell variable.
2612 * variable.c (target_environment): If we find a v_noexport
2613 variable for SHELL, add a SHELL variable with the env_shell value.
2614 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2615 * doc/make.texi (Variables/Recursion): Ditto.
2617 2004-11-28 Paul D. Smith <psmith@gnu.org>
2619 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2620 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2621 Patch by Alessandro Vesely.
2623 2004-11-12 Paul D. Smith <psmith@gnu.org>
2625 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2626 the command line if it's inside a string.
2627 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2629 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2631 * function.c (func_lastword): New function: return last word
2632 from the list of words.
2633 * doc/make.texi: Document $(lastword ). Fix broken links in
2634 Quick Reference section.
2636 2004-10-06 Paul D. Smith <psmith@gnu.org>
2638 Apply patch from Alessandro Vesely, provided with bug # 9748.
2639 Fix use of tmpnam() to work with Borland C.
2641 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2642 construction of a temporary filename, and call new function
2643 create_batch_filename().
2644 (create_batch_filename) [WINDOWS32]: New function to create a
2647 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2649 * read.c (record_target_var): Expand simple pattern-specific
2651 * variable.c (initialize_file_variables): Do not expand simple
2652 pattern-specific variable.
2654 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2656 * remake.c (update_file_1): When rebuilding makefiles inherit
2657 dontcare flag from a target that triggered update.
2659 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2661 * variable.c (initialize_file_variables): Mark pattern-specific
2662 variable as a per-target and copy export status.
2664 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2666 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2668 * implicit.c (pattern_search): When considering an implicit rule's
2669 prerequisite check that it is actually a target rather then
2670 just an entry in the file hashtable.
2672 2004-09-21 Paul D. Smith <psmith@gnu.org>
2674 * read.c (readstring): Fix some logic errors in backslash handling.
2675 (eval): Remove some unnecessary processing in buffer handling.
2676 (record_target_var): Assert that parse_variable_definition() succeeded.
2677 Reported by: Markus Mauhart <qwe123@chello.at>.
2679 * misc.c: Removed the sindex() function. All instances of this
2680 function were trivially replaceable by the standard strstr()
2681 function, and that function will always have better (or certainly
2682 no worse) performance than the very simple-minded algorithm
2683 sindex() used. This can matter with complex makefiles.
2684 * make.h: Remove the prototype for sindex().
2685 * function.c (subst_expand): Convert sindex() call to strstr().
2686 This means we no longer need to track the TLEN value so remove that.
2687 (func_findstring): Convert sindex() to strstr().
2688 * commands.c (chop_commands): Convert sindex() calls to strstr().
2689 Suggested by: Markus Mauhart <qwe123@chello.at>.
2691 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2692 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2693 If SHELL is set to CMD.EXE then assume it's batch-mode and
2694 non-unixy. I wrote the code differently from the patch, though,
2695 to make it safer. This also resolves bug #9174.
2697 2004-09-20 Paul D. Smith <psmith@gnu.org>
2699 * expand.c (variable_expand_string): Modify to invoke
2700 patsubst_expand() instead of subst_expand(); the latter didn't
2701 handle suffix patterns correctly.
2702 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2703 was used only from variable_expand_string() and is no longer used
2705 (func_subst): Ditto, on call to subst_expand().
2706 (patsubst_expand): Require the percent pointers to point to the
2707 character after the %, not to the % itself.
2708 * read.c (record_files): New call criteria for patsubst_expand().
2709 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2710 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2712 2004-09-19 Paul D. Smith <psmith@gnu.org>
2714 * function.c (subst_expand): Fix a check in by_word: look for a
2715 previous blank if we're beyond the beginning of the string, not
2716 the beginning of the word.
2717 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2719 2004-05-16 Paul D. Smith <psmith@gnu.org>
2721 * remake.c (update_goal_chain): Change the argument specifying
2722 whether we're rebuilding makefiles to be a global variable,
2723 REBUILDING_MAKEFILES.
2724 (complain): Extract the code that complains about no rules to make
2725 a target into a separate function.
2726 (update_file_1): If we tried to rebuild a file during the makefile
2727 rebuild phase and it was dontcare, then no message was printed.
2728 If we then try to build the same file during the normal build,
2729 print a message this time.
2730 (remake_file): Don't complain about un-remake-able files when
2731 we're rebuilding makefiles.
2733 2004-05-11 Paul D. Smith <psmith@gnu.org>
2735 * job.c (construct_command_argv_internal): OS/2 patches from
2736 Andreas Buening <andreas.buening@nexgo.de>.
2738 2004-05-10 Paul D. Smith <psmith@gnu.org>
2740 * remake.c (update_file): Don't walk the double-colon chain unless
2741 this is a double-colon rule. Fix suggested by Boris Kolpackov
2742 <boris@kolpackov.net>.
2744 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2745 * readme.vms: New section describing OpenVMS support and issues.
2746 * default.c (default_variables): Add support for IA64.
2747 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2748 without some privilege aborts make with the error
2749 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2750 pressing Ctrl+Y and the input device is no terminal. The change
2751 catches this error and just continues.
2753 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2755 2004-04-25 Paul D. Smith <psmith@gnu.org>
2757 * commands.c (set_file_variables): Set $< properly in the face of
2758 order-only prerequisites.
2759 Patch from Boris Kolpackov <boris@kolpackov.net>
2761 2004-04-21 Bob Byrnes <byrnes@curl.com>
2763 * main.c (main): Notice failures to remake makefiles.
2765 2004-03-28 Paul D. Smith <psmith@gnu.org>
2767 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2769 * job.c: No default shell for RISC OS.
2770 (load_too_high): Hard-code the return to 1.
2771 (construct_command_argv_internal): No sh_chars or sh_cmds.
2772 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2774 2004-03-20 Paul D. Smith <psmith@gnu.org>
2776 * variable.c (do_variable_definition): Don't append from the
2777 global set if a previous non-appending target-specific variable
2778 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2781 * expand.c (reference_variable): Don't give up on variables with
2782 no value that have the target-specific append flag set: they might
2783 have a value after all. Reported by Oliver Schmidt
2784 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2785 <nikulin@dx1cmd.inp.nsk.su>.
2787 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2788 refer to absolute pathnames in directories that don't exist: some
2789 portion of the makefile could create those directories before we
2790 match the pattern. Fixes bugs #775 and #108.
2792 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2794 * main.c (main): Free makefile_mtimes if we have any.
2795 * README.W32.template: Update documentation for the current status
2796 of the MS-Windows port.
2797 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2798 environment variable is sometimes already defined which causes the
2800 * main.c (debug_signal_handler): Only define this function if
2801 SIGUSR1 is available.
2803 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2805 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2806 * README.OS2.template: Documentation updates.
2807 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2808 link line for safety.
2809 * maintMakefile (build.sh.in): Remove an extraneous ")".
2810 * job.c (child_execute_job): Close saved FDs.
2811 * job.c (exec_command) [OS/2]: exec_command(): If the command
2812 can't be exec'ed and if the shell is not Unix-sh, then try again
2813 with argv = { "cmd", "/c", ... }. Normally, this code is never
2814 reached for the cmd shell unless the command really doesn't exist.
2815 (construct_command_argv_internal) [OS/2]: The code for cmd
2816 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2817 The CMD builtin commands are case insensitive so use strcasecmp().
2819 2004-03-19 Paul D. Smith <psmith@gnu.org>
2821 * read.c (do_define): Re-order line counter increment so the count
2822 is accurate (we were losing one line per define). Reported by
2823 Dave Yost <Dave@Yost.com>.
2825 2004-03-06 Paul D. Smith <psmith@gnu.org>
2827 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2829 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2830 * misc.c (message,error,fatal): Ditto.
2831 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2832 * config.h.W32.template: Ditto.
2833 * config.h-vms.template: Ditto.
2834 * config.ami.template: Ditto.
2836 2004-03-04 Paul D. Smith <psmith@gnu.org>
2838 * README.template: Add a note about broken /bin/sh on SunOS
2839 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2841 * misc.c (message, error, fatal): Don't use "..." if we're using
2842 varargs. ansi2knr should handle this but it doesn't work: it
2843 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2844 done. On many systems (SunOS for example) va_dcl is a #define.
2845 So, force the use of the non-"..." version on pre-ANSI compilers.
2847 * maintMakefile (sign-dist): Create some rules to help automate
2848 the new GNU ftp upload method.
2850 2004-02-24 Paul D. Smith <psmith@gnu.org>
2852 * config.h.W32.template: Add HAVE_STDARG_H
2853 * config.h-vms.template: Ditto.
2854 * config.ami.template: Ditto.
2856 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2858 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2859 * build_w32.bat: Remove extra "+".
2861 2004-02-23 Paul D. Smith <psmith@gnu.org>
2863 * make.h: Create an UNUSED macro to mark unused parameters.
2864 * (many): Clean up warnings by applying UNUSED, fixing
2865 signed/unsigned incompatibilities, etc.
2867 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2869 * filedef.h: Name the command_state enumeration.
2870 * file.c (set_command_state): Use the enumeration in the function
2873 * configure.in: Explicitly set SET_MAKE to empty, to disable
2874 MAKE=make even when no make already exists. Fix bug #3823.
2876 2004-02-22 Paul D. Smith <psmith@gnu.org>
2878 * maintMakefile: Perl script to clean up all non-CVS files. Use
2879 it on all the subdirectories for the cvs-clean target.
2881 * main.c (decode_switches): Require non-empty strings for all our
2882 string command-line options. Fixes Debian bug # 164165.
2884 * configure.in: Check for stdarg.h and varargs.h.
2885 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2886 for printing messages.
2887 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2892 A number of patches for OS/2 support from Andreas Buening
2893 <andreas.buening@nexgo.de>:
2895 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2896 disable the SIGCHLD handler.
2897 (reap_children) [OS/2]: Remove special handling of job_rfd.
2898 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2899 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2900 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2901 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2902 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2905 2004-02-21 Paul D. Smith <psmith@gnu.org>
2907 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2908 <mail@kristov.de> reports that if process_begin() fails we don't
2909 handle the error condition correctly in all cases.
2910 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2911 to have a newline on the message.
2913 * job.c (construct_command_argv_internal): Add "test" to UNIX
2914 sh_cmds[]. Fixes Savannah bug # 7606.
2916 2004-02-04 Paul D. Smith <psmith@gnu.org>
2918 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2919 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2920 Hartmut Becker <Hartmut.Becker@hp.com>.
2922 2004-01-21 Paul D. Smith <psmith@gnu.org>
2924 * job.c (load_too_high): Implement an algorithm to control the
2925 "thundering herd" problem when using -l to control job creation
2926 via the load average. The system only recomputes the load once a
2927 second but we can start many jobs in a second. To solve this we
2928 keep track of the number of jobs started in the last second and
2929 apply a weight to try to guess what a correct load would be.
2930 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2931 Also fixes bug #4693.
2932 (reap_children): Decrease the job count for this second.
2933 (start_job_command): Increase the job count for this second.
2935 * read.c (conditional_line): Expand the text after ifn?def before
2936 checking to see if it's a single word. Fixes bug #7257.
2938 2004-01-09 Paul D. Smith <psmith@gnu.org>
2940 * file.c (print_file): Recurse to print all targets in
2941 double-colon rules. Fixes bug #4518, reported (with patch) by
2942 Andrew Chatham <chatham@google.com>.
2944 2004-01-07 Paul D. Smith <psmith@gnu.org>
2946 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2947 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2948 AC_FUNC_SETVBUF_REVERSED.
2950 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2951 (MAKE Variable): Fix Savannah bug #4898.
2953 * job.c (construct_command_argv_internal): Add "!" to the list of
2954 shell escape chars. POSIX sh allows it to appear before a
2955 command, to negate the exit code. Fixes bug #6404.
2957 * implicit.c (pattern_search): When matching an implicit rule,
2958 remember which dependencies have the ignore_mtime flag set.
2959 Original fix provided in Savannah patch #2349, by Benoit
2960 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2962 2003-11-22 Paul D. Smith <psmith@gnu.org>
2964 * README.W32.template (Outputs): Clarification on -j with
2965 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2968 2003-11-02 Paul D. Smith <psmith@gnu.org>
2970 * function.c (func_if): Strip all the trailing whitespace from the
2971 condition, then don't expand it. Fixed bug # 5798.
2973 * expand.c (recursively_expand_for_file): If we're expanding a
2974 variable with no file context, then use the variable's context.
2977 2003-10-21 Paul D. Smith <psmith@gnu.org>
2979 * main.c (log_working_directory): Add newlines to printf()s.
2981 * README.cvs: Add a note to ignore warnings during autoreconf.
2983 * maintMakefile (po_repo): Set a new URL for PO file updates.
2984 (get-config/config.guess get-config/config.sub): Get these files
2985 from the Savannah config project instead of ftp.gnu.org.
2987 2003-10-05 Paul Eggert <eggert@twinsun.com>
2989 * main.c (main): Avoid potential subscript error if environ has
2992 2003-08-22 Paul D. Smith <psmith@gnu.org>
2994 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2995 systems which don't yet implement the C89 standard :-/.
2997 2003-07-18 Paul D. Smith <psmith@gnu.org>
2999 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3000 [WINDOWS32]: Initialize hash.
3002 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3004 * dir.c (read_dirstream): Provide a workaround for broken versions of
3005 the MinGW dirent structure.
3007 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3009 * w32/include/dirent.h: Add __MINGW32__ filter.
3011 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3013 * make.h: Add global declaration of *make_host.
3014 * main.c (print_usage): Remove local declaration of *make_host.
3015 (print_version): Display "This program built for ..." after Copyright
3018 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3020 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3021 execution of "makeinfo --html make.texi".
3023 2003-04-30 Paul D. Smith <psmith@gnu.org>
3025 * build.template: Make some changes to maybe allow this script to
3026 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3028 * README.OS2.template: New file for OS/2 support. Original
3029 contributed by Andreas Buening.
3030 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3033 2003-04-19 Paul D. Smith <psmith@gnu.org>
3035 Fix bug #1405: allow a target to match multiple pattern-specific
3038 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3039 variable.c, where they've always belonged.
3040 * rule.h: Move the prototypes and struct pattern_var as well.
3041 * variable.c (initialize_file_variables): Invoke
3042 lookup_pattern_var() in a loop, until no more matches are found.
3043 If a match is found, create a new variable set for the target's
3044 pattern variables. Then merge the contents of each matching
3045 pattern variable set into the target's pattern variable set.
3046 (lookup_pattern_var): Change this function to be usable
3047 in a loop. It takes a starting position: if NULL, start at the
3048 beginning; if non-NULL, start with the pattern variable after that
3049 position, and return the next matching pattern.
3050 (create_pattern_var): Create a unique instance of
3051 pattern-specific variables for every definition in the makefile.
3052 Don't combine the same pattern together. This allows us to
3053 process the variable handling properly even when the same pattern
3054 is used multiple times.
3055 (parse_variable_definition): New function: break out the parsing
3056 of a variable definition line from try_variable_definition.
3057 (try_variable_definition): Call parse_variable_definition to
3059 (print_variable_data_base): Print out pattern-specific variables.
3060 * variable.h (struct variable): Remember when a variable is
3061 conditional. Also remember its flavor.
3062 (struct pattern_var): Instead of keeping a variable set, we just
3063 keep a single variable for each pattern.
3064 * read.c (record_target_var): Each pattern variable contains only a
3065 single variable, not a set, so create it properly.
3066 * doc/make.texi (Pattern-specific): Document the new behavior.
3068 2003-04-17 Paul D. Smith <psmith@gnu.org>
3070 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3071 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3072 file/directory naming rules for VMS so I can't tell whether this
3075 2003-04-09 Paul D. Smith <psmith@gnu.org>
3077 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3078 DOS-style pathnames: backslash separators and drive specifiers.
3080 2003-03-28 Paul D. Smith <psmith@gnu.org>
3082 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3083 the intermediate flag on all targets. Fixes bug #2515.
3085 2003-03-24 Paul D. Smith <psmith@gnu.org>
3087 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3088 Upgrade to autoconf 2.57 and automake 1.7.3.
3090 * job.c: More OS/2 changes from Andreas Buening.
3092 * file.c (print_file): Fix variable initialization.
3095 * remake.c (notice_finished_file):
3097 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3098 some calls (like readdir()) return NULL in valid situations
3099 without resetting errno. Fixes bug #2846.
3101 2003-02-25 Paul D. Smith <psmith@gnu.org>
3103 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3105 * job.c (_is_unixy_shell) [OS/2]: New function.
3106 Set default shell to /bin/sh.
3107 (reap_children): Close the job_rfd pipe here since we don't use a
3109 (set_child_handler_action_flags): define this to empty on OS/2.
3110 (start_job_command): Close the jobserver pipe and use
3111 child_execute_job() instead of fork/exec.
3112 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3113 rather than exec'ing, then reconfigure stdin/stdout.
3114 (exec_command): Rewrite to use spawn instead of exec. Return the
3117 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3118 in DOS. Handle the TEMP environment variable as in DOS. Don't
3119 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3120 use -j in DOS mode. Use child_execute_job() instead of
3123 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3126 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3127 prototypes that return values.
3129 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3131 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3132 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3134 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3137 2003-02-24 Paul D. Smith <psmith@gnu.org>
3139 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3140 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3141 (child_execute_job) [VMS]: Handle error status properly.
3142 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3144 * function.c (func_shell): Use EINTRLOOP() while reading from the
3145 subshell pipe (Fixes bug #2502).
3146 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3148 * main.c (main): Ditto.
3150 2003-01-30 Paul D. Smith <psmith@gnu.org>
3152 * read.c (eval): eval() was not fully reentrant, because the
3153 collapsed buffer was static. Change it to be an automatic
3154 variable so that eval() can be invoked recursively.
3156 (eval): Apply patch # 1022: fix memory reference error on long
3157 target-specific variable lines.
3158 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3160 * function.c (check_numeric): Combine the is_numeric() function
3161 into this function, since it's only called from one place.
3162 Constify this function. Have it print the incorrect string in the
3163 error message. Fixes bug #2407.
3164 (strip_whitespace): Constify.
3165 (func_if): Constify.
3166 * expand.c (expand_argument): Constify.
3168 2003-01-29 Paul D. Smith <psmith@gnu.org>
3170 Fix bug # 2169, also reported by other people on various systems.
3172 * make.h: Some systems, such as Solaris and PTX, do not fully
3173 implement POSIX-compliant SA_RESTART functionality; important
3174 system calls like stat() and readdir() can still fail with EINTR
3175 even if SA_RESTART has been set on the signal handler. So,
3176 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3177 EINTR for system calls which return -1 or 0 (NULL), respectively,
3179 Also, remove the old atomic_stat()/atomic_readdir() and
3180 HAVE_BROKEN_RESTART handling.
3182 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3184 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3185 * remake.c (touch_file): Ditto.
3187 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3188 * read.c (construct_include_path): Ditto.
3189 * remake.c (name_mtime): Ditto.
3190 * vpath.c (selective_vpath_search): Ditto.
3191 * dir.c (find_directory): Ditto.
3192 (local_stat): Ditto.
3193 (find_directory): Use ENULLLOOP() to wrap opendir().
3194 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3196 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3197 atomic_readdir() handling.
3199 2003-01-22 Paul D. Smith <psmith@gnu.org>
3201 * function.c (func_call): Fix Bug #1744. If we're inside a
3202 recursive invocation of $(call ...), mask any of the outer
3203 invocation's arguments that aren't used by this one, so that this
3204 invocation doesn't "inherit" them accidentally.
3206 2002-12-05 Paul D. Smith <psmith@gnu.org>
3208 * function.c (subst_expand): Valery Khamenia reported a
3209 pathological performance hit when doing substitutions on very
3210 large values with lots of words: turns out we were invoking
3211 strlen() a ridiculous number of times. Instead of having each
3212 call to sindex() call strlen() again, keep track of how much of
3213 the text we've seen and pass the length to sindex().
3215 2002-11-19 Paul D. Smith <psmith@gnu.org>
3217 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3220 2002-11-16 Paul D. Smith <psmith@gnu.org>
3222 * NMakefile.template (OBJS): Add hash.c object file.
3223 * SMakefile.template (srcs): Ditto.
3224 * Makefile.ami (objs): Ditto.
3225 * build_w32.bat: Ditto.
3227 * Makefile.DOS.template: Remove extra dependencies.
3229 2002-10-25 Paul D. Smith <psmith@gnu.org>
3231 * expand.c (install_variable_buffer): New function. Install a new
3232 variable_buffer context and return the previous one.
3233 (restore_variable_buffer): New function. Free the current
3234 variable_buffer context and put a previously saved one back.
3235 * variable.h: Prototypes for {install,restore}_variable_buffer.
3236 * function.c (func_eval): Push a new variable_buffer context
3237 before we eval, then restore the old one when we're done.
3240 * read.c (install_conditionals): New function. Install a new
3241 conditional context and return the previous one.
3242 (restore_conditionals): New function. Free the current
3243 conditional context and put a previously saved one back.
3244 (eval): Use the {install,restore}_conditionals for "include"
3246 (eval_buffer): Use {install,restore}_conditionals to preserve the
3247 present conditional state before we evaluate the buffer.
3250 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3252 (Recursion): Add a variable index entry for CURDIR.
3254 * README.cvs: Update to appropriate versions.
3255 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3256 don't need to copy loadavg.c: automake is smart enough to create
3257 it for me. Still have a bug in automake related to ansi2knr tho.
3259 2002-10-14 Paul D. Smith <psmith@gnu.org>
3261 * remake.c (notice_finished_file): Only touch targets if they have
3262 at least one command (as per POSIX). Resolve Bug #1418.
3264 * *.c: Convert to using ANSI C-style function definitions.
3265 * Makefile.am: Enable the ansi2knr feature of automake.
3266 * configure.in: ditto.
3268 2002-10-13 Paul D. Smith <psmith@gnu.org>
3270 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3271 for automatic variable values like $^, etc. In the case of very
3272 large lists of prerequisites this causes problems. Instead reuse
3273 a static buffer (resizeable) for each variable.
3275 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3276 target-specific variable definitions. Check for it and set an
3278 (record_target_var): Set the export field to v_export if the
3279 "exported" flag is set.
3280 * doc/make.texi (Target-specific): Document the ability to use
3283 * doc/make.texi: Change the name of the section on automatic
3284 variables from "Automatic" to "Automatic Variables". Added text
3285 clarifying the scope of automatic variables.
3287 2002-10-04 Paul D. Smith <psmith@gnu.org>
3289 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3291 (record_files): Ditto.
3293 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3294 the search for the '=' to only within the enclosing parens.
3296 2002-10-03 Paul D. Smith <psmith@gnu.org>
3298 Version 3.80 released.
3300 * dir.c: Change hash functions to use K&R function definition style.
3301 * function.c: Ditto.
3303 * variable.c: Ditto.
3305 Update to automake 1.7.
3307 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3308 (pdf): Remove this target as automake now provides one.
3310 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3312 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3314 * makefile.com: Updates for GNU make 3.80.
3315 * makefile.vms: Ditto.
3317 2002-09-23 Paul D. Smith <psmith@gnu.org>
3319 * read.c (enum make_word_type): Remove w_comment.
3320 (get_next_mword): Don't treat comment characters as special; where
3321 this function is used we will never see a comment (it's stripped
3322 before we get here) and treating comments specially means that
3323 targets like "foo\#bar" aren't handled properly.
3325 2002-09-18 Paul D. Smith <psmith@gnu.org>
3327 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3329 * read.c (eval): Expansion of arguments to export/unexport was
3330 ignoring all arguments after the first one. Change the algorithm
3331 to expand the whole line once, then parse the results.
3333 2002-09-17 Paul D. Smith <psmith@gnu.org>
3335 Fix Bug #940 (plus another bug I found while looking at this):
3337 * read.c (record_target_var): enter_file() will add a new entry if
3338 it's a double-colon target: we don't want to do that in this
3339 situation. Invoke lookup_file() and only enter_file() if it does
3340 not already exist. If the file we get back is a double-colon then
3341 add this variable to the "root" double-colon target.
3343 * variable.c (initialize_file_variables): If this file is a
3344 double-colon target but is not the "root" target, then initialize
3345 the root and make the root's variable list the parent of our
3348 2002-09-13 Paul D. Smith <psmith@gnu.org>
3350 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3352 * hash.c (round_up_2): Get rid of a warning.
3354 2002-09-12 Paul D. Smith <psmith@gnu.org>
3356 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3357 so it doesn't complain about getloadavg.c.
3359 * commands.c (set_file_variables): Make sure we always alloca() at
3360 least 1 character for the value of $? (for '\0').
3362 2002-09-11 Paul D. Smith <psmith@gnu.org>
3364 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3365 macro to use RESULT instead of the incorrect _RESULT_.
3367 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3368 and atomic_readdir(). We need to #include dirent.h to get this to
3370 * misc.c (atomic_readdir): Fix typos.
3372 2002-09-10 Paul D. Smith <psmith@gnu.org>
3374 * read.c (eval): Expand variable lists given to export and
3375 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3376 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3378 * doc/make.texi (Variables/Recursion): Document this.
3379 (Conditional Syntax): And here.
3381 2002-09-09 Paul D. Smith <psmith@gnu.org>
3383 * configure.in: Check for memmove().
3385 2002-09-07 Paul D. Smith <psmith@gnu.org>
3387 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3388 Michael Sterrett <msterret@coat.com> reports that while it has
3389 SA_RESTART, it does not work properly.
3391 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3392 that invokes stat() and loops to do it again if it returns EINTR.
3393 (atomic_readdir): Ditto, with readdir().
3395 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3396 and readdir() to atomic_stat() and atomic_readdir().
3398 2002-09-04 Paul D. Smith <psmith@gnu.org>
3400 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3401 reports that GNU make sometimes doesn't recognize that targets can
3402 be made, when directories can be created as prerequisites. He
3403 reports that changing the order of predicates in the DEP->changed
3404 flag test so that lookup_file() is always performed, solves this
3407 2002-08-08 Paul D. Smith <psmith@gnu.org>
3409 * configure.in: Require a newer version of gettext.
3411 * misc.c (perror_with_name): Translate the format string (for
3412 right-to-left language support).
3413 (pfatal_with_name): Ditto.
3415 * main.c: Create a static array of strings to store the usage
3416 text. This is done to facilitate translations.
3417 (struct command_switch): Remove argdesc and description fields.
3418 (switches): Remove values for obsolete fields.
3419 (print_usage): Print each element of the usage array.
3421 * hash.c: Change function definitions to be K&R style.
3423 2002-08-02 Paul D. Smith <psmith@gnu.org>
3425 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3426 this one because it's too hard to get right. We'll look at it for
3428 * main.c (main): Don't create the .TARGETS variable.
3429 * variable.c (handle_special_var): Don't handle .TARGETS.
3431 2002-08-01 Paul D. Smith <psmith@gnu.org>
3433 * main.c (switches): Add a new option, -B (--always-make). If
3434 specified, make will rebuild all targets that it encounters even
3435 if they don't appear to be out of date.
3436 (always_make_flag): New flag.
3437 * make.h: Extern always_make_flag.
3438 * remake.c (update_file_1): Check always_make_flag; if it's set we
3439 will always rebuild any target we can, even if none of its
3440 prerequisites are newer.
3443 * doc/make.texi (Shell Function): Make it clear that make
3444 variables marked as "export" are not passed to instances of the
3447 Add new introspection variable .VARIABLES and .TARGETS.
3449 * variable.c (handle_special_var): New function. If the variable
3450 reference passed in is "special" (.VARIABLES or .TARGETS),
3451 calculate the new value if necessary. .VARIABLES is handled here:
3452 walk through the hash of defined variables and construct a value
3453 which is a list of the names. .TARGETS is handled by
3454 build_target_list().
3455 (lookup_variable): Invoke handle_special_var().
3456 * file.c (build_target_list): Walk through the hask of known files
3457 and construct a list of the names of all the ones marked as
3459 * main.c (main): Initialize them to empty (and as simple variables).
3460 * doc/make.texi (Special Variables): Document them.
3461 * NEWS: Mention them.
3463 * variable.h (struct variable): Add a new flag "exportable" which
3464 is true if the variable name is valid for export.
3465 * variable.c (define_variable_in_set): Set "exportable" when a new
3466 variable is defined.
3467 (target_environment): Use the "exportable" flag instead of
3468 re-checking the name here... an efficiency improvement.
3470 2002-07-31 Paul D. Smith <psmith@gnu.org>
3472 * config.h-vms.template: Updates to build on VMS. Thanks to
3473 Brian_Benning@aksteel.com for helping verify the build.
3474 * makefile.com: Build the new hash.c file.
3475 * hash.h: Use strcpmi(), not stricmp(), in the
3476 HAVE_CASE_INSENSITIVE_FS case.
3478 2002-07-30 Paul D. Smith <psmith@gnu.org>
3480 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3481 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3482 Reported by <Brian_Benning@aksteel.com>.
3484 2002-07-10 Paul D. Smith <psmith@gnu.org>
3486 * variable.c (pop_variable_scope): Remove variable made unused by
3487 new hash infrastructure.
3488 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3489 comparisons as well as name comparisons.
3490 * variable.h: Add a prototype for new hash_init_function_table().
3491 * file.c (lookup_file): Remove variables made unused by new hash
3493 * dir.c (directory_contents_hash_2): Missing return of hash value.
3494 (dir_contents_file_exists_p): Remove variables made unused by new
3495 hash infrastructure.
3498 Installed Greg McGary's integration of the hash functions from the
3499 GNU id-utils package:
3501 2002-07-10 Greg McGary <greg@mcgary.org>
3503 * scripts/functions/filter-out: Add literals to to the
3504 pattern space in order to add complexity, and trigger
3505 use of an internal hash table. Fix documentation strings.
3506 * scripts/targets/INTERMEDIATE: Reverse order of files
3507 passed to expected `rm' command.
3509 2002-07-10 Greg McGary <greg@mcgary.org>

3601 2002-07-10 Paul D. Smith <psmith@gnu.org>
3603 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3604 prerequisite list. A real SysV make will expand the entire
3605 prerequisites list _twice_: we don't do that as it's a big
3606 backward-compatibility problem. We only replace those specific
3609 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3610 references left in the list of prerequisites. Check for .POSIX as
3611 we record targets, so we can disable non-POSIX behavior while
3612 reading makefiles as well as running them.
3613 (eval): Check the prerequisite list to see if we have anything
3614 that looks like a SysV prerequisite variable reference.
3616 2002-07-09 Paul D. Smith <psmith@gnu.org>
3618 * doc/make.texi (Prerequisite Types): Add a new section describing
3619 order-only prerequisites.
3621 * read.c (uniquize_deps): If we have the same file as both a
3622 normal and order-only prereq, get rid of the order-only prereq,
3623 since the normal one supersedes it.
3625 2002-07-08 Paul D. Smith <psmith@gnu.org>
3627 * AUTHORS: Added Greg McGary to the AUTHORS file.
3628 * NEWS: Blurbed order-only prerequisites.
3629 * file.c (print_file): Show order-only deps properly when printing
3632 * maintMakefile: Add "update" targets for wget'ing the latest
3633 versions of various external files. Taken from Makefile.maint in
3636 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3637 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3639 2002-07-07 Paul D. Smith <psmith@gnu.org>
3641 * po/*.po: Remove. We'll use wget to retrieve them at release
3644 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3645 rather than a shell you get an exception. Make sure we look up
3646 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3648 * remake.c (notice_finished_file): Fix handling of -t flag.
3649 Patch provided by Henning Makholm <henning@makholm.net>.
3651 * implicit.c (pattern_search): Some systems apparently run short
3652 of stack space, and using alloca() in this function caused an
3653 overrun. I modified it to use xmalloc() on the two variables
3654 which seemed like they might get large. Fixes Bug #476.
3656 * main.c (print_version): Update copyright notice to conform with
3658 (print_usage): Update help output.
3660 * function.c (func_eval): Create a new make function, $(eval
3661 ...). Expand the arguments, put them into a buffer, then invoke
3662 eval_buffer() on the resulting string.
3663 (func_quote): Create a new function, $(quote VARNAME). Inserts
3664 the value of the variable VARNAME without expanding it any
3667 * read.c (struct ebuffer): Change the linebuffer structure to an
3668 "eval buffer", which can be either a file or a buffer.
3669 (eval_makefile): Move the code in the old read_makefile() which
3670 located a makefile into here: create a struct ebuffer with that
3671 information. Have it invoke the new function eval() with that
3673 (eval_buffer): Create a new function that creates a struct ebuffer
3674 that holds a string buffer instead of a file. Have it invoke
3675 eval() with that ebuffer.
3676 (eval): New function that contains the guts of the old
3677 read_makefile() function: this function parses makefiles. Obtains
3678 data to parse from the provided ebuffer. Some modifications to
3679 make the flow of the function cleaner and clearer. Still could
3680 use some work here...
3681 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3682 contents of the define/endef variable from the ebuffer.
3683 (readstring): Read the next line from a string-style ebuffer.
3684 (readline): Read the next line from an ebuffer. If it's a string
3685 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3688 * dep.h (eval_buffer): Prototype eval_buffer();
3690 * variable.c (do_variable_definition): Make sure that all
3691 non-target-specific variables are registered in the global set.
3692 If we're invoked from an $(eval ...) we might be inside a $(call
3693 ...) or other function which has pushed a variable scope; we still
3694 want to define our variables from evaluated makefile code in the
3697 2002-07-03 Greg McGary <greg@mcgary.org>
3699 * dep.h (struct dep) [ignore_mtime]: New member.
3700 [changed]: convert to a bitfield.
3701 * implicit.c (pattern_search): Zero ignore_mtime.
3702 * main.c (main, handle_non_switch_argument): Likewise.
3703 * rule.c (convert_suffix_rule): Likewise.
3704 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3705 (read_makefile): Parse '|' in prerequisite list.
3706 (uniquize_deps): Consider ignore_mtime when comparing deps.
3707 * remake.c (update_file_1, check_dep): Don't force remake for
3708 dependencies that have d->ignore_mtime.
3709 * commands.c (FILE_LIST_SEPARATOR): New constant.
3710 (set_file_variables): Don't include a
3711 prerequisite in $+, $^ or $? if d->ignore_mtime.
3714 2002-06-18 Paul D. Smith <psmith@gnu.org>
3716 * make.texinfo: Updates for next revision. New date/rev/etc.
3717 Recreate all Info menus. Change license on the manual to the GNU
3718 Free Documentation License. A number of typos.
3719 (Variables Simplify): Don't use "-" before it's defined.
3720 (Automatic Prerequisites): Rewrite the target example to work
3721 properly if the compile fails. Remove incorrect comments about
3722 how "set -e" behaves.
3723 (Text Functions): Move the "word", "wordlist", "words", and
3724 "firstword" functions here, from "File Name Functions".
3725 * make-stds.texi: Update from latest GNU version.
3726 * fdl.texi: (created) Import the latest GNU version.
3728 2002-06-06 Paul D. Smith <psmith@gnu.org>
3730 * variable.c (do_variable_definition): New function: extract the
3731 part of try_variable_definition() that actually sets the value
3732 into a separate function.
3733 (try_variable_definition): Call do_variable_definition() after
3734 parsing the variable definition string.
3735 (define_variable_in_set): Make the name argument const.
3737 * variable.h (enum variable_flavor): Make public.
3738 (do_variable_definition): Create prototype.
3740 * read.c (read_all_makefiles): Create a new built-in variable,
3742 (read_makefile): Add each makefile read in to this variable value.
3744 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3746 * Makefile.DOS.template: Tweak according to changes in the
3747 distribution. Add back the dependencies of *.o files.
3749 * configh.dos.template: Synchronize with config.h.in.
3751 2002-05-09 Paul D. Smith <psmith@gnu.org>
3753 * file.c (file_timestamp_now): Use K&R function declaration.
3755 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3756 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3757 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3758 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3759 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3760 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3761 nlist.n_name is a pointer rather than an array.
3763 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3764 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3765 * configure.in: Use it instead of the old version.
3767 * main.c (main): Prefer setvbuf() to setlinebuf().
3769 2002-05-08 Paul D. Smith <psmith@gnu.org>
3771 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3772 (loadavg_LDADD): Ditto.
3774 2002-04-29 Paul D. Smith <psmith@gnu.org>
3776 * expand.c (recursively_expand_for_file): Rename
3777 recursively_expand() to recursively_expand_for_file() and provide
3778 an extra argument, struct file. If the argument is provided, set
3779 the variable scope to that of the file before expanding.
3780 * variable.h (recursively_expand): Make this a macro that invokes
3781 recursively_expand_for_file() with a NULL file pointer.
3782 * variable.c (target_environment): Call the renamed function and
3783 provide the current file context.
3784 Fixes Debian bug #144306.
3786 2002-04-28 Paul D. Smith <psmith@gnu.org>
3788 Allow $(call ...) user-defined variables to be self-referencing
3789 without throwing an error. Allows implementation of transitive
3790 closures, among other possibly useful things.
3791 Requested by: Philip Guenther <guenther@sendmail.com>
3793 * variable.h (struct variable): Add a new field: exp_count, and
3794 new macros to hold its size and maximum value.
3795 (warn_undefined): Make this a macro.
3796 * variable.c (define_variable_in_set): Initialize it.
3797 * expand.c (recursively_expand): If we detect recursive expansion
3798 of a variable, check the exp_count field. If it's greater than 0
3799 allow the recursion and decrement the count.
3800 (warn_undefined): Remove this (now a macro in variable.h).
3801 * function.c (func_call): Before we expand the user-defined
3802 function, modify its exp_count field to contain the maximum
3803 number of recursive calls we'll allow. After the call, reset it
3806 2002-04-21 Paul D. Smith <psmith@gnu.org>
3808 Modified to use latest autoconf (2.53), automake (1.6.1), and
3809 gettext (0.11.1). We're using gettext's new "external" support,
3810 to avoid including libintl source with GNU make.
3812 * README.cvs: New file. Explain how to build GNU make from CVS.
3814 * configure.in: Modify checking for the system glob library.
3815 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3816 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3817 etc. will manage it correctly). Set an automake conditional
3818 USE_LOCAL_GLOB to decide whether to compile the glob library.
3820 * getloadavg.c (main): Include make.h in the "TEST" program to
3823 * Makefile.am: Remove special rules for loadavg. Replace them
3824 with Automake capabilities for building extra programs.
3826 * signame.c: This file does nothing if the system provide
3827 strsignal(). If not, it implements strsignal(). If the system
3828 doesn't define sys_siglist, then we make our own; otherwise we use
3830 * signame.h: Removed.
3832 * main.c (main): No need to invoke signame_init(). Update copyright.
3834 * ABOUT-NLS: Removed.
3835 * gettext.c: Removed.
3836 * gettext.h: Get a simplified copy from the gettext package.
3838 * i18n/*.po: Moved to po/.
3841 * config/*: Created. Contains package configuration helper files.
3842 * config.guess, config.sub: Moved to config directory.
3844 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3845 Rework to use new-style autoconf features. Use the "external"
3846 mode for gettext. Make the build.sh config file conditional on
3847 whether build.sh.in exists, to avoid autoconf errors.
3848 * acinclude.m4: Removed almost all macros as being obsolete.
3849 Rewrote remaining macros to use AC_DEFINE.
3850 * acconfig.h: Removed.
3852 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3853 conditional to handle customs support. Remove special handling
3856 2002-04-20 Paul D. Smith <psmith@gnu.org>
3858 * function.c (func_call): Don't mark the argument variables $1,
3859 etc. as recursive. They've already been fully expanded so
3860 there's no need to do it again, and doing so strips escaped $'s.
3861 Reported by Sebastian Glita <glseba@yahoo.com>.
3863 * remake.c (notice_finished_file): Walk through double-colon
3864 entries via the prev field, not the next field!
3865 Reported by Greg McGary <greg@mcgary.org>.
3867 * main.c (main): If the user specifies -q and asks for a specific
3868 target which is a makefile, we got an assert. In that case it
3869 turns out we should continue normally instead.
3871 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3873 * i18n/he.po: Installed a new translation.
3875 2002-01-07 Paul D. Smith <psmith@gnu.org>
3877 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3879 2001-12-04 Paul D. Smith <psmith@gnu.org>
3881 * i18n/ja.po: Installed an updated translation.
3883 2001-09-06 Paul Eggert <eggert@twinsun.com>
3885 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3886 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3888 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3890 (main): Get rid of any avoidable limit on stack size.
3892 2001-09-04 Paul D. Smith <psmith@gnu.org>
3894 * i18n/da.po: Installed an updated translation.
3896 2001-08-03 Paul D. Smith <psmith@gnu.org>
3898 * i18n/fr.po: Installed an updated translation.
3899 Resolves Debian bug #106720.
3901 2001-06-13 Paul D. Smith <psmith@gnu.org>
3903 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3906 2001-06-11 Paul D. Smith <psmith@gnu.org>
3908 * i18n/ko.po: Installed a new translation.
3910 2001-05-06 Paul D. Smith <psmith@gnu.org>
3912 Modify the EINTR handling.
3914 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3915 the way in which we manage the file descriptor/signal handler race
3916 trap to be more efficient.
3918 2001-05-06 Paul Eggert <eggert@twinsun.com>
3920 Restart almost all system calls that are interrupted, instead
3921 of worrying about EINTR. The lone exception is the read() for
3924 * configure.in (HAVE_SA_RESTART): New macro.
3925 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3926 * main.c (main): Use SA_RESTART instead of the old,
3927 nonstandard SA_INTERRUPT.
3929 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3930 * main.c (bsd_signal): New function or macro,
3931 if the implementation doesn't supply it.
3932 (The bsd_signal function will be in POSIX 1003.1-200x.)
3933 (HANDLESIG): Remove.
3934 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3936 * make.h (EINTR_SET): Remove.
3937 (SA_RESTART): New macro.
3939 * arscan.c (ar_member_touch): Don't worry about EINTR.
3940 * function.c (func_shell): Likewise.
3941 * job.c (reap_children, free_child, new_job): Likewise.
3942 * main.c (main): Likewise.
3943 * remake.c (touch_file, name_mtime): Likewise.
3945 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3946 if fstat failed with errno!=EINTR, the error was ignored.
3948 * job.c (set_child_handler_action_flags): New function.
3949 (new_job): Use it to temporarily clear the SIGCHLD action flags
3950 while reading the token.
3952 2001-05-02 Paul D. Smith <psmith@gnu.org>
3954 * job.c (start_job_command): Don't add define/endef per-line flags
3955 to the top-level flags setting.
3957 2001-04-03 Paul D. Smith <psmith@gnu.org>
3959 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3960 bit on error, so check for odd return values, not non-0 return
3962 (VMS_get_member_info): Calculate the timezone differences correctly.
3963 Reported by John Fowler <jfowler@nyx.net>.
3966 2001-03-14 Paul D. Smith <psmith@gnu.org>
3968 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3969 value before invoking define_variable().
3970 Reported by John Fowler <jfowler@nyx.net>.
3972 2001-02-07 Paul D. Smith <psmith@gnu.org>
3974 * read.c (record_target_var): If we reset the variable due to a
3975 command-line variable setting overriding it, turn off the "append"
3978 2001-01-17 Paul D. Smith <psmith@gnu.org>
3980 * variable.c (lookup_variable) [VMS]: When getting values from the
3981 environment, allocate enough space for the _value_ plus escapes,
3982 not enough space for the name plus escapes :-/.
3983 Reported by John Fowler <jfowler@nyx.net>.
3985 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3986 warnings that make generates, so it doesn't look like an error.
3987 Reported by Karl Berry <karl@gnu.org>.
3990 Fix for PR/2020: Rework appended target-specific variables. I'm
3991 fairly confident this algorithm is finally correct.
3993 * expand.c (allocated_variable_append): Rewrite. Instead of
3994 expanding each appended variable then adding all the expanded
3995 strings together, we append all the unexpanded values going up
3996 through the variable set contexts, then expand the final result.
3997 This behaves just like non-target-specific appended variable
3998 values, while the old way didn't in various corner cases.
3999 (variable_append): New function: recursively append the unexpanded
4000 value of a variable, walking from the outermost variable scope to
4002 * variable.c (lookup_variable): Remove the code that looked up the
4003 variable set list if the found variable was "append". We don't
4005 (lookup_variable_in_set): Make this non-static so we can use it
4007 (try_variable_definition): Use lookup_variable_in_set() rather
4008 than faking out current_variable_set_list by hand (cleanup).
4009 * variable.h: Add a prototype for the now non-static
4010 lookup_variable_in_set().
4012 2000-11-17 Paul D. Smith <psmith@gnu.org>
4014 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4015 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4016 before throwing a fit.
4018 2000-11-17 Paul D. Smith <psmith@gnu.org>
4020 * read.c (readline): CRLF calculations had a hole, if you hit the
4021 buffer grow scenario just right. Reworked the algorithm to avoid
4022 the need for len or lastlen at all. Problem description with
4023 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4025 2000-10-24 Paul D. Smith <psmith@gnu.org>
4027 * gettext.c (SWAP): Declare this with the prototype, otherwise
4028 some systems don't work (non-32-bit? Reported for Cray T3E).
4029 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4031 2000-10-05 Paul D. Smith <psmith@gnu.org>
4033 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4034 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4036 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4038 2000-09-22 Paul D. Smith <psmith@gnu.org>
4040 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4041 parts of the real gettext.h here, and we expect to really include
4042 the real gettext.h later. If we keep this #define, it's ignored.
4044 2000-09-21 Paul D. Smith <psmith@gnu.org>
4046 * main.c (log_working_directory): Rework the text to use complete
4047 sentences, to make life simpler for the translators.
4049 2000-08-29 Paul D. Smith <psmith@gnu.org>
4051 * file.c (remove_intermediates): Print a debug message before we
4052 remove intermediate files, so the user (if she uses -d) knows
4055 2000-08-21 Paul D. Smith <psmith@gnu.org>
4057 * variable.c (try_variable_definition): Change how we handle
4058 target-specific append variable defns: instead of just setting the
4059 value, expand it as an append _but_ only within the current
4060 target's context. Otherwise we lose all but the last value if the
4061 variable is appended more than once within the current target
4062 context. Fixes PR/1831.
4064 2000-08-16 Paul D. Smith <psmith@gnu.org>
4066 * function.c (func_shell): Nul-terminate the buffer before
4067 printing an exec error message (just in case it's not!).
4068 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4070 2000-07-25 Paul D. Smith <psmith@gnu.org>
4072 * job.c (construct_command_argv_internal): Add "~" to the list of
4073 sh_chars[] which disallow optimizing out the shell call.
4075 2000-07-23 Paul Eggert <eggert@twinsun.com>
4077 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4078 supersedes --disable-nsec-timestamps.
4079 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4080 * README: Remove --disable-nsec-timestamps.
4082 * filedef.h (struct file.low_resolution_time): New member.
4083 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4084 * remake.c (update_file_1):
4085 Avoid spurious rebuilds due to low resolution time stamps,
4086 generalizing the earlier code that applied only to archive members.
4087 (f_mtime): Archive members always have low resolution time stamps.
4089 * configure.in: Remove --disable-nsec-timestamps, as this has
4090 been superseded by .LOW_RESOLUTION_TIME.
4092 2000-07-23 Paul Eggert <eggert@twinsun.com>
4094 * configure.in (enable_nsec_timestamps): Renamed from
4095 make_cv_nsec_timestamps, since enable/disable options
4096 shouldn't be cached.
4098 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4099 and Paul Eggert <eggert@twinsun.com>
4101 * file.c (file_timestamp_now):
4102 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4103 so that clock_gettime is not linked unless needed.
4105 * filedef.h (FILE_TIMESTAMP_HI_RES):
4106 Remove definition; "configure" now does this.
4108 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4109 to before high resolution file timestamp check,
4110 since that check now uses uintmax_t.
4111 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4112 high resolution file timestamps.
4113 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4114 so that we don't link in clock_gettime unnecessarily.
4116 2000-07-17 Paul D. Smith <psmith@gnu.org>
4118 * i18n/ja.po: New version of the translation file.
4120 2000-07-07 Paul D. Smith <psmith@gnu.org>
4122 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4123 the offset calculation.
4124 (name_mtime): Replace EINTR test with EINTR_SET macro.
4126 2000-07-07 Paul Eggert <eggert@twinsun.com>
4130 * remake.c (update_file_1):
4131 Avoid spurious rebuilds of archive members due to their
4132 timestamp resolution being only one second.
4133 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4134 the clock's resolution being lower than file timestamps'.
4135 When warning about future timestamps, report only the discrepancy,
4136 not the absolute value of the timestamp and the current time.
4138 * file.c (file_timestamp_now): New arg RESOLUTION.
4139 * filedef.h (file_timestamp_now): Likewise.
4140 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4142 2000-07-05 Paul D. Smith <psmith@gnu.org>
4144 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4145 to listp. Fixes PR/1793.
4147 2000-06-26 Paul Eggert <eggert@twinsun.com>
4149 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4151 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4153 * remake.c (f_mtime): Remove unused var memtime.
4155 2000-06-25 Martin Buchholz <martin@xemacs.org>
4157 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.

4160 2000-06-23 Paul D. Smith <psmith@gnu.org>
4162 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4163 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4164 * make.h: Define these macros.
4166 * Version 3.79.1 released.
4168 * configure.in: Add a new option, --disable-nsec-timestamps, to
4169 avoid using sub-second timestamps on systems that support it. It
4170 can lead to problems, e.g. if your makefile relies on "cp -p".
4171 * README.template: Document the issue with "cp -p".
4173 * config.guess, config.sub: Updated.
