76 as well. See Savannah bug #32511.
78 2011-09-16 Paul Smith <psmith@gnu.org>

127 2011-05-07 Eli Zaretskii <eliz@gnu.org>
129 * job.c (construct_command_argv_internal): Don't assume shellflags
130 is always non-NULL. Escape-protect characters special to the

507 * arscan.c (VMS_get_member_info) [VMS]: Fix timezone computation.
508 (ar_scan) [VMS]: Fix const error.
510 2009-11-12 Boris Kolpackov <boris@codesynthesis.com>
512 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
513 which allows the caller to get the index of the matching directory.
515 * make.h (vpath_search): Update prototype.
517 * remake.c (library_search): Implement linker-compatible library
518 search. Use the new VPATH_SEARCH index functionality to keep track
519 of the directory index for each match. Select the match with the
520 lowest directory index.
522 * implicit.c (pattern_search): Pass NULL for the index arguments in
523 the VPATH_SEARCH call.
525 * doc/make.texi (Directory Search for Link Libraries): Describe the
526 new search behavior.
528 * NEWS: Add a note about the new behavior.
530 2009-10-25 Paul Smith <psmith@gnu.org>
532 * AUTHORS, et.al.: Update copyright years.
534 * implicit.c (stemlen_compare): Fix qsort() compare bug that
535 caused implicit rules with equal stem lengths to be sorted
536 indeterminately.
538 2009-10-24 Paul Smith <psmith@gnu.org>
540 * main.c (usage): Add --eval to the usage string.
541 (switches): Add the --eval switch.
542 (main): If --eval is given, add them to the simply-expanded variable
543 -*-eval-flags-*- (necessary to allow recursion to work properly).
544 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
546 * NEWS: Describe the new --eval command line argument.
547 * doc/make.texi (Options Summary): Document --eval.
549 * dep.h: eval_buffer() returns void.
550 * read.c (eval_buffer): Ditto.
551 (eval): Ditto.
553 * variable.h (define_variable_cname): New macro for constant
554 variable names.
555 * default.c (set_default_suffixes): Use it.
556 * main.c (main): Ditto.
557 (handle_non_switch_argument): Ditto.
558 (define_makeflags): Ditto.
559 * read.c (read_all_makefiles): Ditto.
560 * variable.c (define_automatic_variables): Ditto.
562 * commands.c (dep_hash_cmp): Avoid casts.
563 (dep_hash_1): Ditto.
564 (dep_hash_2): Ditto.
566 2009-10-22 Boris Kolpackov <boris@codesynthesis.com>
568 * read.c (read_all_makefiles): Mark the default makefile dependency
569 dontcare.
571 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
573 * read.c (do_undefine): Free the expanded variable name.
575 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
576 to normal upgrade logic from dep_hash_cmp to set_file_variables.
578 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
580 * dep.h (uniquize_deps): Remove.
582 * read.c (uniquize_deps): Merge into set_file_variables in
583 commands.c.
584 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
586 * commands.c (set_file_variables): Avoid modifying the dep
587 chain to achieve uniqueness. Fixes savannah bug 25780.
589 * implicit.c (pattern_search): Instead of re-setting all automatic
590 variables for each rule we try, just update $*.
592 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
594 * variable.h (undefine_variable_in_set): New function declaration.
595 (undefine_variable_global): New macro.
597 * variable.c (undefine_variable_in_set): New function implementation.
599 * read.c (vmodifiers): Add undefine_v modifier.
600 (parse_var_assignment): Parse undefine.
601 (do_undefine): Handle the undefine directive.
602 (eval): Call do_undefine if undefine_v is set.
604 * main.c (.FEATURES): Add a keyword to indicate the new feature.
606 * doc/make.texi (Undefine Directive): Describe the new directive.
608 * NEWS: Add a note about the new directive.
610 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
612 * implicit.c (pattern_search): Initialize file variables only
613 if we need to parse a rule that requires the second expansion.
615 2009-10-03 Paul Smith <psmith@gnu.org>
617 * make.h: Include <alloca.h> even on systems where __GNUC__ is
618 defined. Not sure why it was done the other way.
619 Requested by David Boyce <dsb@boyski.com>.
621 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
623 * dep.h (dep): Add the DONTCARE bitfield.
625 * filedef.h (file):Add the NO_DIAG bitfield.
627 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
628 not struct file (a file can be a dependency of many targets,
629 some don't care, some do).
631 * remake.c (update_goal_chain): Propagate DONTCARE from struct
632 dep to struct file before updating the goal and restore it
633 afterwards.
634 (update_file): Don't prune the dependency graph if this target
635 has failed but the diagnostics hasn't been issued.
636 (complain): Scan the file's dependency graph to find the file
637 that caused the failure.
638 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
639 whether to print diagnostics.
641 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
643 2009-09-28 Paul Smith <psmith@gnu.org>
645 * doc/make.texi (Pattern Intro): Move the match algorithm
646 discussion into the "Pattern Match" node.
647 (Pattern Match): Expand on the pattern rule matching algorithm.
649 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
651 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
652 much of the command line on a single pass.
654 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
656 * varible.c (create_pattern_var): Insert variables into the
657 PATTERN_VARS list in the shortest patterns first order.
659 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
660 used to sort the rules.
661 (stemlen_compare): Compare two tryrule elements.
662 (pattern_search): Sort the rules so that they are in the shortest
663 stem first order.
665 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
667 * doc/make.texi (Pattern-specific Variable Values): Describe the
668 new pattern-specific variables application order.

670 search order.
672 * NEWS: Add a note about the new behavior.
674 2009-09-27 Paul Smith <psmith@gnu.org>
676 * doc/make.texi (Double-Colon): Mention that pattern rules with
677 double-colons have a different meaning. Savannah bug #27497.
679 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
681 * configh.dos.template: Remove unconditional definition of
682 SYS_SIGLIST_DECLARED.
683 Include <sys/version.h> because ports of GCC 4.3.0 and later no
684 longer include it, so macros like __DJGPP_MINOR__ are no longer
685 defined automatically.
687 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
688 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
689 instead of using the hardcoded ones.
690 (SUBDIRS): doc subdir added.
691 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
692 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
693 create html formated docs. texi2html may not be ported to DOS.
694 (make.info, make.dvi, make.ps, make.html): Make targets depend on
695 'make.texi'.
696 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
697 -I switch to look in ./ instead of ./doc.
698 (html): Target depend on html-recursive instead of make_1.html.
699 (make_1.html): Removed.
700 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
701 (all-recursive): Allow for more than one subdir in the build
702 process.
703 (mostlyclean-recursive, clean-recursive, distclean-recursive)
704 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
705 (tags-recursive): Allow for more than one subdir in the build
706 process.
707 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
708 targets. Enter into doc/ to produce the targets.
709 (all-am): $(INFO_DEPS) replaced by info.
711 2009-09-26 Paul Smith <psmith@gnu.org>
713 * read.c (record_files): Use free_ns() to free struct nameseq.
714 (eval): Ditto.
716 * rule.c (freerule): Use free_dep_chain().
718 * read.c (record_files): Free FILENAMES chain for implicit rules.
719 (eval): Static pattern targets go into the string cache.
721 * function.c (string_glob): Free NAME in the nameseq chain.
723 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
725 * implicit.c (pattern_search): Terminate early if we haven't
726 found any rules to try (performance improvement).
728 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
730 * implicit.c (pattern_search): Merge three parallel arrays,
731 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
732 of struct TRYRULE. In the old version the latter two arrays
733 had insufficient length.
735 2009-09-24 Paul Smith <psmith@gnu.org>
737 * implicit.c (pattern_search): Add back support for order-only
738 prerequisites for secondary expansion implicit rules, that were
739 accidentally dropped. If we find a "|", enable order-only mode
740 and set IGNORE_MTIME on all deps that are seen afterward.
741 (pattern_search): Fix memory leaks: for intermediate files where
742 we've already set the file variable and pattern variable sets, be
743 sure to either save or free them as appropriate.
745 2009-09-23 Paul Smith <psmith@gnu.org>
747 Rework the way secondary expansion is stored, for efficiency.
748 This changes secondary expansion so that ONLY WHEN we know we have
749 a possibility of needing secondary expansion, do we defer the
750 secondary expansion. This means more parsing the deps but we use
751 a lot less memory (due to the strcache). Also, this fixes
752 Savannah bug #18622.
754 * read.c (eval): Don't parse the dep string here anymore.
755 (record_files): Take the dep argument as an unparsed string. If
756 secondary expansion is enabled AND the prereq string has a '$' in
757 it, then set NEED_2ND_EXPANSION and keep the entire string.
758 Otherwise, parse the dep string here to construct the dep list
759 with the names in the strcache.
761 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
762 duplicate the name string (others are in the strcache).
764 * implicit.c: Remove struct idep and free_idep_chain(): unused.
765 (struct patdeps): New structure to store prereq information.
766 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
767 which prerequisites need expansion, and expand only those.
769 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
770 and enter_prereqs(). split_prereqs() takes a fully-expanded string
771 and splits it into a DEP list, handling order-only prereqs.
772 (enter_prereqs): This function enters a list of DEPs into the file
773 database. If there's a stem defined, expand any pattern chars.
774 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
775 set. Use the above functions.
776 (snap_deps): Only perform second expansion on prereqs that need it,
777 as defined by the NEED_2ND_EXPANSION flag.
778 (print_prereqs): New function to print the prereqs
779 (print_file): Call print_prereqs() rather than print inline.
781 * hash.h (STRING_COMPARE): Take advantage of strcache() by
782 comparing pointers.
783 (STRING_N_COMPARE): Ditto.
784 (ISTRING_COMPARE): Ditto.
786 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
787 (parse_file_seq): Return void*
788 * read.c (parse_file_seq): Return void*.
789 (eval): Invoke macroized version of parse_file_seq()
790 * default.c (set_default_suffixes): Ditto.
791 * file.c (split_prereqs): Ditto.
792 * function.c (string_glob): Ditto.
793 * main.c (main): Ditto.
794 * rule.c (install_pattern_rule): Ditto.
796 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
798 2009-09-16 Paul Smith <psmith@gnu.org>
800 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
801 convert to macros.
802 * dep.h: Create alloc_dep() / free_dep() macros.
804 * implicit.c (pattern_search): Take advantage of the new
805 parse_file_seq() to add the directory prefix to each prereq.
807 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
808 all. Avoid reversing chains. Support adding prefixes.
809 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
810 cached/non-cached results.
811 (eval): Remove multi_glob() & invoke new parse_file_seq().
812 * rule.c (install_pattern_rule): Ditto.
813 * main.c (main): Ditto.
814 * implicit.c (pattern_search): Ditto.
815 * function.c (string_glob): Ditto.
816 * file.c (parse_prereqs): Ditto.
817 * default.c (set_default_suffixes): Ditto.
819 * variable.c (parse_variable_definition): Don't run off the end of
820 the string if it ends in whitespace (found with valgrind).
822 * commands.c (set_file_variables): Keep space for all targets in
823 $? if -B is given (found with valgrind).
825 2009-09-15 Paul Smith <psmith@gnu.org>
827 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
828 (xcalloc): Add new function.
829 * make.h: New declarations.
831 * ar.c (ar_glob_match): New calling method for concat().
832 * main.c (main): Ditto.
833 (decode_env_switches): Ditto.
834 * read.c (eval_makefile): Ditto.
835 (tilde_expand): Ditto.
836 (parse_file_seq): Ditto.
837 * variable.c (target_environment): Ditto.
838 (sync_Path_environment): Ditto.
840 * ar.c (ar_glob_match): Use xcalloc().
841 * dir.c (file_impossible): Ditto.
842 * file.c (enter_file): Ditto.
843 * job.c (new_job): Ditto.
844 * read.c (parse_file_seq): Ditto.
845 * vmsfunctions.c (opendir): Ditto.
847 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
849 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
850 inside the loop that looks up environment for PATH.
852 2009-08-31 Eli Zaretskii <eliz@gnu.org>
854 * function.c (windows32_openpipe): Update envp after calling
855 sync_Path_environment.
857 2009-08-02 Paul Smith <psmith@gnu.org>
859 * remake.c (notice_finished_file): Ensure file->cmds is not null
860 before looping through them. Fixes Savannah bug #21824.
862 * doc/make.texi (Wildcard Examples): Clarify when objects is
863 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
864 (Include): Clarify the behavior of -include.
865 Fixes Savannah bug #18963.
867 2009-08-01 Paul Smith <psmith@gnu.org>
869 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
870 etc. come on the command line. Fixes Savannah bug #27093.
872 * expand.c (expand_argument): If the argument is large enough use
873 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
875 * variable.c (do_variable_definition): Avoid using alloca() to
876 hold values, which can be large. Fixes Savannah bug #23960.
878 * job.c (new_job): Use memmove() instead of strcpy() since both
879 pointers are in the same memory block. Fixes Savannah bug #27148.
880 Patch by Petr Machata.
882 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
884 * job.c (construct_command_argv_internal): Add "ulimit" and
885 "unset" to the sh_cmds for Unixy shells.
887 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
889 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
890 that set make_cv_sys_gnu_glob, so they are also correctly set
891 when the cache has been populated before.
893 2009-07-04 Eli Zaretskii <eliz@gnu.org>
895 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
896 exist, as realpath(3) does where it's supported.
898 2006-07-04 Eli Zaretskii <eliz@gnu.org>
900 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
901 (abspath): Support systems that define HAVE_DOS_PATHS (have
902 drive letters in their file names). Use IS_PATHSEP instead of a
903 literal '/' comparison. Fixes Savannah bug #26886.
905 2009-06-14 Paul Smith <psmith@gnu.org>
907 * remake.c (update_file_1): Remember the original file we marked
908 as updating, so we can clear that flag again. If we find a target
909 via vpath, FILE might change.
910 (check_dep): Ditto. Fixes Savannah bug #13529.
911 Patch by Reid Madsen <reid.madsen@tek.com>.
913 2009-06-13 Paul Smith <psmith@gnu.org>
915 * doc/make.texi (MAKEFILES Variable): Be explicit that files
916 included by MAKEFILES cannot give default goals.
917 * read.c (eval): If set_default is not set, pass the no-default-goal
918 value when we read included makefiles. Fixes Savannah bug #13401.
920 * ar.c (ar_name): Ensure that targets with empty parens aren't
921 considered archive member references: archive members must have a
922 non-empty "member" string. Fixes Savannah bug #18435.
924 * function.c (string_glob): Rely on multi_glob() to determine
925 whether files exist or not. Remove call to file_exists_p() which
926 is not always correct. Fixes Savannah bug #21231.
927 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
928 then only files that really exist will be returned.
929 * dep.h: Add new argument to multi_glob().
930 * rule.c (install_pattern_rule): Ditto.
931 * read.c (eval): Ditto.
932 * main.c (main): Ditto.
933 * implicit.c (pattern_search): Ditto.
934 * file.c (parse_prereqs): Ditto.
935 * default.c (set_default_suffixes): Ditto.
937 2009-06-09 Paul Smith <psmith@gnu.org>
939 * commands.c (set_file_variables): If always_make_flag is set,
940 always add the prereq to $?. Fixes Savannah bug #17825.
942 * remake.c (update_file_1): When rebuilding deps of FILE, also try
943 to rebuild the deps of all the also_make targets for that file.
944 Fixes Savannah bug #19108.
946 * implicit.c (pattern_search): Undo test for is_target, added by
947 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
948 Rule Search Algorithm". Fixes Savannah bug #17752.
950 * main.c (clean_jobserver): Clear the jobserver_fds options and
951 set job_slots to the default when we clean up.
952 (define_makeflags): Return the new MAKEFLAGS value.
953 (main): Reset MAKEFLAGS in the environment when we re-exec.
954 Fixes Savannah bug #18124.
956 2009-06-08 Paul Smith <psmith@gnu.org>
958 * read.c (eval): Collapse continuations post-semicolon on target-
959 specific variables. Fixes Savannah bug #17521.
961 2009-06-07 Paul Smith <psmith@gnu.org>
963 * job.c (reap_children): For older systems without waitpid() (are
964 there any of these left?) run wait(2) inside EINTRLOOP to handle
965 EINTR errors. Fixes Savannah bug #16401.
967 * (various): Debug message cleanup. Fixes Savannah bug #16469.
969 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
971 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
972 not the end, to catch second expansion $(eval ...) defining new
973 target/prereq relationships during snap_deps.
974 Fixes Savannah bug #24622.
976 * read.c (record_files): The second-expansion "f->updating" hack
977 was not completely correct: if assumed that the target with
978 commands always had prerequisites; if one didn't then the ordering
979 was messed up. Fixed for now to use f->updating to decide whether
980 to preserve the last element in the deps list... but this whole
981 area of constructing and reversing the deps list is too confusing
982 and needs to be reworked. Fixes Savannah bug #21198.
984 2009-06-06 Paul Smith <psmith@gnu.org>
986 * hash.c (hash_insert): Remove useless test for NULL.
987 Fixes Savannah bug #21823.
989 * make.h: Move SET_STACK_SIZE determination to make.h.
990 * main.c (main): New global variable, STACK_LIMIT, holds the
991 original stack limit when make was started.
992 * job.c (start_job_command): Reset the stack limit, if we changed it.
993 Fixes Savannah bug #22010.
995 * remake.c (check_dep): Only set the target's state to not-started
996 if it's not already running. Found this while testing -j10 builds
997 of glibc: various targets were being rebuilt multiple times.
998 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
999 bug #15919.
1001 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1002 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1003 Bugzilla bug 10246.
1005 2009-06-04 Paul Smith <psmith@gnu.org>
1007 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1009 * maintMakefile: Modify access of config and gnulib Savannah
1010 modules to use GIT instead of CVS.
1012 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1013 Fixes Savannah bug #24655.
1015 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1016 this can happen during some invocations of $(eval ...) for example.
1017 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1019 2009-06-02 Paul Smith <psmith@gnu.org>
1021 * configure.in: Check for fileno()
1022 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1023 for the makefile file so invocations of $(shell ...) don't inherit it.
1024 Fixes Savannah bug #24277.
1026 2009-06-01 Paul Smith <psmith@gnu.org>
1028 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1029 expansion was handled incorrectly. Rework the default goal
1030 handling to save the variable only. Remove default_goal_file and
1031 default_goal_name.
1032 * read.c (eval): Check default_goal_var, not default_goal_name.
1033 * read.c (record_target_var): Don't check default_goal_file here.
1035 2009-05-31 Paul Smith <psmith@gnu.org>
1037 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1038 it, and if the multi_glob() returns nothing (say it expanded to
1039 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1041 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1042 $(and ..) to the reference. Fixes Savannah bug #25694.

1047 * doc/make.texi (Override Directive): Make more clear how
1048 overrides and appends interact.
1049 Elucidates part of Savannah bug #26207.
1051 * read.c (record_target_var): Don't reset the origin on
1052 target-specific variables; try_variable_definition() will handle
1053 this correctly. Fixes Savannah bug #26207.
1055 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1056 Fixes Savannah bug #25712.
1058 * implicit.c (pattern_search): Keep a pointer to the beginning of
1059 the filename and save that instead of the constructed pointer.
1060 Fixes Savannah bug #26593.
1061 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1063 2009-05-30 Paul Smith <psmith@gnu.org>
1065 * doc/make.texi (Multi-Line): Add a description of the new abilities
1066 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1067 "command sequence" vs. "recipe" syntax.

1069 after a define, to create variables with those flavors.
1071 2009-05-25 Paul Smith <psmith@gnu.org>
1073 Reworked the parser for variable assignments to allow multiple
1074 modifiers, and in any order. Also allows variable and
1075 prerequisites to be modifier names ('export', 'private', etc.)
1077 * NEWS: Add notes about user-visible changes.
1079 * read.c (struct vmodifiers): Remember what modifiers were seen.
1080 (parse_var_assignment): New function to parse variable assignments.

1096 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1097 prototype for xmalloc.
1098 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1099 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1100 Loop over an array of extensions, instead of duplicating the same
1101 code inline. Use SearchPath followed by CreateFile, instead of
1102 the obsolete OpenFile. Fixes Savannah bug #17277.
1103 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1104 to `find_file'. Fixes Savannah bug #25662.
1106 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1108 * function.c (func_shell): Don't close pipedes[1] if it is -1.

1119 variables and prevents their values from being inherited.
1121 * variable.h (struct variable): Add private_var flag to each variable.
1122 Add a flag to specify which list entry switches to the parent target.

1153 of the batch file.
1155 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1157 * README.W32.template: Remove obsolete text about non-support for
1158 -jN without Unixy shell. Remove obsolete text about not supplying
1159 Visual Studio project files (we do supply them). Modify text to
1160 prefer GCC builds to MSC builds.

1185 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1186 (TEXINFOS): Value changed to `doc/make.texi'.
1187 (.SUFFIXES): Use .texi instead of .texinfo.
1188 (make.info, make.dvi): Depend on doc/make.texi.

1192 $(MAKEINFO) to look in doc/. Use --no-split.
1193 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1194 switch to $(MAKEINFO) to look in doc/.
1195 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

1205 HAVE_DECL_SYS_SIGLIST.
1207 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1208 build does not use child_execute_job.
1210 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1211 export the SHELL environment variable to the child.
1213 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1215 * config.h.W32: Include sys/types.h.
1216 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1218 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

1222 2007-11-04 Paul Smith <psmith@gnu.org>
1224 * doc/make.texi: Convert references to "commands", "command
1225 lines", and "command script" to "recipe".
1226 * NEWS: Ditto.
1227 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1228 Ditto.
1230 2007-10-27 Bruno Haible <bruno@clisp.org>
1232 * remake.c (f_mtime): Print time difference values between 100 and
1233 ULONG_MAX in fixed-point notation rather than in exponention notation.
1235 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1237 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1238 a more complex value than a simple shell: if it's not a default
1239 shell now then expand it and see if is a default shell then.
1241 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1243 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1244 pathnames, with const strings.
1245 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1248 2007-10-10 Paul Smith <psmith@gnu.org>
1250 * make.h: Add a prototype for w32_kill() (change suggested by

1265 2007-09-11 Paul Smith <psmith@gnu.org>
1267 * doc/make.texi (Special Variables): Moved this into the "How to
1268 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1270 "Special Variables" section.
1271 (Rule Introduction): Reference .RECIPEPREFIX.
1272 (Simple Makefile): Ditto.
1273 (Rule Syntax): Ditto.
1274 (Command Syntax): Ditto.
1275 (Error Messages): Ditto.
1277 2007-09-10 Paul Smith <psmith@gnu.org>
1279 * commands.c (print_commands): Don't print an extra line in the
1280 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1282 * read.c (construct_include_path): Add the full string to the cache; we
1283 were chopping the last char.
1285 * NEWS: Announce the .RECIPEPREFIX special variable.
1286 * variable.c (lookup_special_var): Rename from handle_special_var().
1287 (lookup_variable): Call the new name.
1288 (set_special_var): New function: handle setting of special variables.
1289 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1292 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1293 * main.c (main): Create the .RECIPEPREFIX special variable.
1294 * read.c (eval): Remove the cmd_prefix characters from the command
1295 scripts here, so they're not stored in the commands array at all,
1296 rather than waiting and stripping them out during command construction.
1297 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1299 2007-08-15 Paul Smith <psmith@gnu.org>
1301 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1302 file has had the section info removed, so add some to make.texi
1303 before we include it.
1305 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1307 * remake.c (check_dep): Reset the target state for intermediate
1308 files. They might have been considered before but not updated

1316 value of FLAGS.
1317 * job.c (construct_command_argv_internal): New argument FLAGS; all
1318 callers changed.

1323 2007-07-13 Paul Smith <psmith@gnu.org>
1325 * file.c (expand_deps): Use variable_buffer as the start of the
1326 buffer, not the original pointer (in case it was reallocated).
1327 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1328 Fixes Savannah bug #20452.
1330 2007-07-04 Paul Smith <psmith@gnu.org>
1332 * (ALL FILES): Update to GPLv3.
1333 * (ALL FILES): Update copyright for 2007.
1335 * main.c (print_version): Move the host type info to the second line.
1337 2007-06-29 Thiemo Seufer <ths@mips.com>

1341 2007-06-13 Paul Smith <psmith@gnu.org>
1343 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1344 "Expansion of a deferred"
1345 Fixes Savannah bug #20018.
1347 * expand.c (variable_expand_for_file): Preserve the value of
1348 reading_file rather than setting it to 0 at the end.

1351 2007-05-11 Paul Smith <psmith@gnu.org>
1353 * job.c (new_job): Add debug info to specify where make found the
1354 command script it is running to build a target.
1355 Fixes Savannah bug #18617.
1357 * default.c (default_suffixes,default_suffix_rules,default_variables):
1358 Add support for Objective C. Fixes Savannah bug #16389.
1359 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1361 * function.c (func_lastword): Initialize p.
1363 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1364 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1365 Dave Korn <dave.korn@artimi.com>
1367 2007-05-08 Paul Smith <psmith@gnu.org>
1369 Fix Savannah bug #19656:
1371 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1373 * make.h: Change all case-insensitive string compares to use
1374 strcasecmp() (from POSIX). If we don't have that but do have one
1375 of the others, define strcasecmp to be one of those instead. If
1376 we don't have any, declare a prototype for our own version.
1378 * misc.c (strcasecmp): Use this if we can't find any native
1379 case-insensitive string comparison function.
1380 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1381 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1382 strcmpi().
1383 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1384 strcasecmp() instead of stricmp().
1385 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1386 instead of strcmpi().
1387 * acinclude.m4: Remove the strcasecmp() check from here.
1389 2007-03-21 Paul Smith <psmith@gnu.org>
1391 * configure.in: Don't turn on case-insensitive file system support
1392 if --disable-... is given. Fixes Savannah bug #19348.
1394 2007-03-19 Paul Smith <psmith@gnu.org>
1396 * ALL: Use the strcache for all file name strings, or other
1397 strings which we will never free. The goal is to save memory by
1398 avoiding duplicate copies of strings. However, at the moment this
1399 doesn't save much memory in most situations: due to secondary
1400 expansion we actually save prerequisite lists twice (once before
1401 the secondary expansion, and then again after it's been parsed
1402 into individual file names in the dep list). We will resolve this
1403 in a future change, by doing the parsing up-front for targets
1404 where secondary expansion is not set.
1406 Moving things into the strcache also allows us to use const
1407 pointers in many more places.
1409 2007-01-03 Paul Smith <psmith@gnu.org>
1411 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1412 the function, not just the first. Fixes Savannah bug #18680.
1414 2006-11-18 Paul Smith <psmith@gnu.org>
1416 * strcache.c (strcache_add_len): Don't allocate a new buffer
1417 unless the string is not already nil-terminated. Technically this
1418 is a violation of the standard, since we may be passed an array
1419 that is not long enough to test one past. However, in make this
1420 is never true since we only use nil-terminated strings or
1421 sub-strings thereof.
1423 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1425 * main.c: New global cmd_prefix, defaults to '\t'.
1426 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1427 of '\t'.
1429 * dir.c: Constified.
1430 (dir_contents_file_exists_p): Check for an error return from
1431 readdir(), just in case.
1433 * commands.c: Constified.
1434 * default.c: Constified.
1435 * expand.c: Constified.
1436 * function.c: Partial constification.
1437 * variable.c: Partial constification.
1438 * vmsify.c: Constification. Hard to test this but I hope I didn't
1439 screw it up!
1440 * vpath.c: Partial constification.
1441 * w32/pathstuff.c: Partial constification.
1443 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1445 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1446 backslashes and drive letters as absolute.
1448 2006-10-22 Paul Smith <psmith@gnu.org>
1450 * main.c (struct command_switch): Use const and void*.
1452 2006-10-21 Paul Smith <psmith@gnu.org>
1454 * ar.c: Constified.
1455 * arscan.c: Constified.
1457 2006-09-30 Paul Smith <psmith@gnu.org>
1459 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1460 point to lastword since the example was updated.
1461 Fixes Savannah bug #16304.
1462 (Secondary Expansion): Correct example description.
1463 Fixes Savannah bug #16468.
1464 (Makefile Contents): Clarify that comments cannot appear within
1465 variable references or function calls.
1466 Fixes Savannah bug #16577.
1467 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1468 Fixes Savannah bug #17701.
1469 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1470 (Prerequisite Types): Added an example of using order-only
1471 prerequisites. Fixes Savannah bug #17880.
1472 (Rule Syntax): "lise" -> "list"
1473 (Multiple Rules): ... -> @dots{}
1474 (Splitting Lines): ditto.
1476 * remake.c (update_file_1): Prereqs that don't exist should be
1477 considered changed, for the purposes of $?.
1478 Fixes Savannah bug #16051.
1480 * make.1: Remove extraneous "+".
1481 Fixes Savannah bug #16652.
1483 2006-09-06 Paul D. Smith <psmith@gnu.org>
1485 * configure.in: Include sys/types.h when checking for sys/wait.h.

1489 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1490 $PATH_SEPARATOR.
1492 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1493 Normally, it is defined in config.h.
1495 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1496 well.
1498 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1499 sh_chars_sh for Windows platforms that emulate Unix.
1501 2006-05-07 Paul D. Smith <psmith@gnu.org>
1503 * README.OS2.template: Updates provided by Andreas Buening
1504 <andreas.buening@nexgo.de>.
1506 2006-04-30 Paul D. Smith <psmith@gnu.org>
1508 * make.h: Include <direct.h> if HAVE_DIRECT_H.

1523 2006-04-09 Paul D. Smith <psmith@gnu.org>
1525 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1527 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1528 inner-scope variables don't mask outer-scope variables.
1530 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1531 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1532 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1533 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1534 values from memory allocation functions: they return void* and so
1535 don't need to be cast. Also remove (char *) casts of arguments to
1536 xrealloc().
1538 * configure.in: Remove checks for memcpy/memmove/strchr.
1540 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1542 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp
1543 calls to memset/memcpy/memmove/memcmp calls.
1544 * expand.c, file.c, function.c, getloadavg.c, implicit.c: Ditto.
1545 * job.c, main.c, misc.c, read.c, remake.c, rule.c: Ditto.
1546 * variable.c, vpath.c: Ditto.
1548 * make.h (EXIT_FAILURE): Should be 1, not 0.
1550 2006-04-06 Paul D. Smith <psmith@gnu.org>
1552 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1553 require an ISO C 1989 standard compiler and runtime library.
1555 * Makefile.am: Remove the ansi2knr feature.
1557 * make.h: Remove the PARAMS() macro definition and all uses of it.
1559 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
1560 * commands.c, commands.h, config.h-vms.template: Ditto.
1561 * dep.h, dir.c, expand.c, filedef.h, function.c: Ditto.
1562 * implicit.c, job.c, job.h, main.c, read.c, remake.c: Ditto.
1563 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
1565 * NEWS: Update.
1567 2006-04-01 Paul D. Smith <psmith@gnu.org>
1569 Version 3.81 released.
1571 * NEWS: Updated for 3.81.
1573 * README.cvs: Mention that vpath builds are not supported out of
1574 CVS. Fixes Savannah bug #16236.
1575 Remove update of make.texi from the list of things to do; we use
1576 version.texi now.
1578 2006-03-26 Paul D. Smith <psmith@gnu.org>
1580 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1581 support from automake, as described in the Texinfo manual.
1583 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1585 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1586 with lastslash, since the latter points to filename, not to
1587 target.
1588 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1589 Declare and define sh_chars_sh[].
1591 2006-03-23 Paul D. Smith <psmith@gnu.org>
1593 * configure.in: Look for build.sh.in in $srcdir so it will be
1594 built for remote configurations as well.
1596 * Makefile.am: Make sure to clean up build.sh during distclean.
1597 Fixes Savannah bug #16166.
1599 * misc.c (log_access): Takes a const char *.
1600 * function.c (fold_newlines): Takes an unsigned int *.
1601 Both fixes for Savannah bug #16170.
1603 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1605 * implicit.c (pattern_search): Call set_file_variables only
1606 if we have prerequisites that need second expansion. Fixes
1607 Savannah bug #16140.
1609 2006-03-19 Paul D. Smith <psmith@gnu.org>
1611 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1612 memory on hosts that don't support it directly.
1614 * README.cvs: Add information on steps for making a release (to
1615 make sure I don't forget any).
1617 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1618 function.
1619 (die): Cleanup code was removed from here; call the new function.
1620 (main): If we are re-execing, clean up the jobserver first so we
1621 don't leak file descriptors.
1622 Reported by Craig Fithian <craig.fithian@citigroup.com>
1624 2006-03-17 Paul D. Smith <psmith@gnu.org>
1626 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1627 allow multiple concurrent runs.
1628 Patch from Joseph Myers <joseph@codesourcery.com>
1630 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1632 * dep.h (struct dep): Add the stem field.
1633 * misc.c (alloc_dep, free_dep): New functions.
1634 (copy_dep_chain): Copy stem.
1635 (free_dep_chain): Use free_dep.
1636 * read.c (record_files): Store stem in the dependency line.
1637 * file.c (expand_deps): Use stem stored in the dependency line. Use
1638 free_dep_chain instead of free_ns_chain.
1639 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1640 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1641 * main.c (main, handle_non_switch_argument): Ditto.
1642 * remake.c (check_dep): Ditto.
1643 * rule.c (convert_suffix_rule, freerule): Ditto.
1645 2006-03-14 Paul D. Smith <psmith@gnu.org>
1647 * expand.c (variable_append): Instead of appending everything then
1648 expanding the result, we expand (or not, if it's simple) each part
1649 as we add it.
1650 (allocated_variable_append): Don't expand the final result.
1651 Fixes Savannah bug #15913.
1653 2006-03-09 Paul Smith <psmith@gnu.org>
1655 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1656 listed non-existent files as changed. Turns out there's a bug in
1657 the Linux kernel builds which means that this change causes
1658 everything to rebuild every time. We will re-introduce this fix
1659 in the next release, to give them time to fix their build system.
1660 Fixes Savannah bug #16002.
1661 Introduces Savannah bug #16051.
1663 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1664 we *don't* find UNIX "/".
1665 Reported by David Ergo <david.ergo@alterface.com>
1667 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1669 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1670 locator function find_and_set_default_shell if SHELL came from the
1671 command line.
1673 2006-02-20 Paul D. Smith <psmith@gnu.org>
1675 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1676 to be null; don't core in that case.
1678 2006-02-19 Paul D. Smith <psmith@gnu.org>
1680 * commands.c (set_file_variables): Realloc, not malloc, the static
1681 string values to avoid memory leaks.
1683 * expand.c (recursively_expand_for_file): Only set reading_file to
1684 an initialized value.
1686 * implicit.c (pattern_search): We need to make a copy of the stem
1687 if we get it from an intermediate dep, since those get freed.
1689 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1690 begin with ".".
1691 (enter_file) [VMS]: Ditto.
1692 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1694 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1696 * job.c (construct_command_argv_internal): Fix last change.
1698 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1699 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1700 the calls to _beginthreadex.
1702 * expand.c (recursively_expand_for_file): Initialize `save' to
1703 prevent compiler warnings.
1705 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1707 * job.c (construct_command_argv_internal): Don't create a temporary
1708 script/batch file if we are under -n. Call _setmode to switch the
1709 script file stream to text mode.
1711 2006-02-17 Paul D. Smith <psmith@gnu.org>
1713 * variable.c (merge_variable_set_lists): Don't try to merge the
1714 global_setlist. Not only is this useless, but it can lead to
1715 circularities in the linked list, if global_setlist->next in one
1716 list gets set to point to another list which also ends in
1717 global_setlist.
1718 Fixes Savannah bug #15757.
1720 2006-02-15 Paul D. Smith <psmith@gnu.org>
1722 Fix for Savannah bug #106.
1724 * expand.c (expanding_var): Keep track of which variable we're
1725 expanding. If no variable is being expanded, it's the same as
1726 reading_file.
1727 * make.h (expanding_var): Declare it.
1728 * expand.c (recursively_expand_for_file): Set expanding_var to the
1729 current variable we're expanding, unless there's no file info in
1730 it (could happen if it comes from the command line or a default
1731 variable). Restore it before we exit.
1732 * expand.c (variable_expand_string): Use the expanding_var file
1733 info instead of the reading_file info.
1734 * function.c (check_numeric): Ditto.
1735 (func_word): Ditto.
1736 (func_wordlist): Ditto.
1737 (func_error): Ditto.
1738 (expand_builtin_function): Ditto.
1739 (handle_function): Ditto.
1741 2006-02-14 Paul D. Smith <psmith@gnu.org>
1743 * read.c (eval): Even if the included filenames expands to the
1744 empty string we still need to free the allocated buffer.
1746 * implicit.c (pattern_search): If we allocated a variable set for
1747 an impossible file, free it.
1748 * variable.c (free_variable_set): New function.
1749 * variable.h: Declare it.
1751 * read.c (read_all_makefiles): Makefile names are kept in the
1752 strcache, so there's never any need to alloc/free them.
1753 (eval): Ditto.
1755 * main.c (main): Add "archives" to the .FEATURES variable if
1756 archive support is enabled.
1757 * doc/make.texi (Special Variables): Document it.
1759 2006-02-13 Paul D. Smith <psmith@gnu.org>
1761 * implicit.c (pattern_search): Add checking for DOS pathnames to
1762 the pattern rule target LASTSLASH manipulation.
1763 Fixes Savannah bug #11183.
1765 2006-02-11 Paul D. Smith <psmith@gnu.org>
1767 * (ALL FILES): Updated copyright and license notices.
1769 2006-02-10 Paul D. Smith <psmith@gnu.org>
1771 A new internal capability: the string cache is a read-only cache
1772 of strings, with a hash table interface for fast lookup. Nothing
1773 in the cache will ever be freed, so there's no need for reference
1774 counting, etc. This is the beginning of a full solution for
1775 Savannah bug #15182, but for now we only store makefile names here.
1777 * strcache.c: New file. Implement a read-only string cache.
1778 * make.h: Add prototypes for new functions.
1779 * main.c (initialize_global_hash_tables): Initialize the string cache.
1780 (print_data_base): Print string cache stats.
1781 * read.c (eval_makefile): Use the string cache to store makefile
1782 names. Rewrite the string allocation to be sure we free everything.
1784 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1786 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1787 directory time stamp didn't change, except on FAT filesystems.
1788 Suggested by J. David Bryan <jdbryan@acm.org>.
1790 2006-02-09 Paul D. Smith <psmith@gnu.org>
1792 * function.c (func_or): Implement a short-circuiting OR function.
1793 (func_and): Implement a short-circuiting AND function.
1794 (function_table_init): Update the table with the new functions.
1795 * doc/make.texi (Conditional Functions): Changed the "if" section
1796 to one on general conditional functions. Added documentation for
1797 $(and ...) and $(or ...) functions.
1798 * NEWS: Note new $(and ...) and $(or ...) functions.
1800 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1802 * job.h (struct child): Add the dontcare bitfield.
1803 * job.c (new_job): Cache dontcare flag.
1804 * job.c (reap_children): Use cached dontcare flag instead of the
1805 one in struct file. Fixes Savannah bug #15641.
1807 2006-02-06 Paul D. Smith <psmith@gnu.org>
1809 * vpath.c (selective_vpath_search): If the file we find has a
1810 timestamp from -o or -W, use that instead of the real time.
1811 * remake.c (f_mtime): If the mtime is a special token from -o or
1812 -W, don't overwrite it with the real mtime.
1813 Fixes Savannah bug #15341.
1815 Updates from Markus Mauhart <qwe123@chello.at>:
1817 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1818 (process_signal, process_last_err, process_exit_code): Manage
1819 invalid handle values.
1820 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1821 manage invalid handles; remove them.
1822 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1823 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1824 * README.cvs: Updates for building from CVS.
1826 2006-02-05 Paul D. Smith <psmith@gnu.org>
1828 * file.c (enter_file): Keep track of the last double_colon entry,
1829 to avoid walking the list every time we want to add a new one.
1830 Fixes Savannah bug #15533.
1831 * filedef.h (struct file): Add a new LAST pointer.
1833 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1834 the comparison. For 64-bits systems the result of the subtraction
1835 might not fit into an int. Use comparison instead.
1836 Fixes Savannah bug #15534.
1838 * doc/make.texi: Update the chapter on writing commands to reflect
1839 the changes made in 3.81 for backslash/newline and SHELL handling.
1841 2006-02-01 Paul D. Smith <psmith@gnu.org>
1843 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1844 variable st is not used when it's not initialized.
1845 Patch from Eli Zaretskii <eliz@gnu.org>.
1847 2006-01-31 Paul D. Smith <psmith@gnu.org>

1853 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1854 J. Grant <jg@jguk.org>.
1856 * main.c: Update the copyright year in the version output.
1857 * prepare_w32.bat: Remove this file from the distribution.
1859 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1861 * remake.c (update_goal_chain): Set g->changed instead of
1862 incrementing it, as it is only 8-bit wide, and could overflow if
1863 many commands got started in update_file.
1865 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1867 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1868 MAXIMUM_WAIT_OBJECTS.
1869 (process_wait_for_any_private): Change dimension of handles[]
1870 array to MAXIMUM_WAIT_OBJECTS.
1871 (process_used_slots): New function.
1872 (process_register): Don't register more processes than the
1873 available number of slots.
1874 (process_easy): Don't start new processes if all slots are used up.
1876 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1877 are already more children than sub_proc.c can handle, behave as if
1878 the load were too high.
1879 (start_job_command): Fix a typo in error message when process_easy
1880 fails.
1882 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1884 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1885 the shell is not sh.exe.
1887 * job.c (create_batch_file): Renamed from create_batch_filename;
1888 all callers changed. Don't close the temporary file; return its
1889 file descriptor instead. New arg FD allows to return the file
1890 descriptor.
1891 (construct_command_argv_internal): Use _fdopen instead of fopen to
1892 open the batch file.
1894 2006-01-04 Paul D. Smith <psmith@gnu.org>
1896 * readme.vms: Updates for case-insensitive VMS file systems from

1913 struct dep when creating a new one.
1915 2005-12-28 Paul D. Smith <psmith@gnu.org>
1917 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1918 disable warnings for MSC.
1919 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1921 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1923 * doc/make.texi (Execution): Add a footnote about changes in
1924 handling of backslash-newline sequences. Mention the differences
1925 on MS-DOS and MS-Windows.
1927 * NEWS: More details about building the MinGW port and a pointer
1928 to README.W32. Fix the section name that describes the new
1929 backward-incompatible processing of backslash-newline sequences.
1930 The special processing of SHELL set to "cmd" is only relevant to
1931 MS-Windows, not MS-DOS.
1933 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1935 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1936 to DWORD, to avoid compiler warnings.
1937 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1938 use %ld in format, to avoid compiler warnings.

1941 (Appending): Fix cross-reference to Setting.
1942 (Special Variables, Secondary Expansion, File Name Functions)
1943 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1944 periods after a sentence.
1945 (Execution): Add @: after "e.g.".
1946 (Environment): Fix punctuation.
1947 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1948 (Shell Function, Target-specific): Add @: after "vs."
1950 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1952 * read.c (record_target_var): Initialize variable's export field
1953 with v_default instead of leaving it "initialized" by whatever
1954 garbage happened to be on the heap.
1956 2005-12-12 Paul D. Smith <psmith@gnu.org>
1958 * make.1: Fix some display errors and document all existing options.
1959 Patch by Mike Frysinger <vapier@gentoo.org>.
1961 2005-12-11 Paul D. Smith <psmith@gnu.org>
1963 * implicit.c (pattern_search): If 2nd expansion is not set for
1964 this implicit rule, replace the pattern with the stem directly,
1965 and don't re-expand the variable list. Along with the other
1966 .SECONDEXPANSION changes below, fixes bug #13781.
1968 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1970 * implicit.c (pattern_search): Mark other files that this rule
1971 builds as targets so that they are not treated as intermediates
1972 by the pattern rule search algorithm. Fixes bug #13022.
1974 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1976 * remake.c (notice_finished_file): Propagate the change of
1977 modification time to all the double-colon entries only if
1978 it is the last one to be updated. Fixes bug #14334.
1980 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1982 * function.c (func_flavor): Implement the flavor function which
1983 returns the flavor of a variable.
1984 * doc/make.texi (Functions for Transforming Text): Document it.
1985 * NEWS: Add it to the list of new functions.
1987 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1989 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1990 variable.
1991 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1992 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1994 2005-10-26 Paul Smith <psmith@gnu.org>
1996 * read.c (record_files): Don't set deps flags if there are no deps.
1997 * maintMakefile: We only need to build the templates when we are
1998 creating a distribution, so don't do it for "all".
2000 2005-10-24 Paul D. Smith <psmith@gnu.org>

2009 prerequisite list was found in a static pattern rule.
2010 (free_dep_chain): Declare a prototype.
2011 * file.c (parse_prereqs): New function: break out some complexity
2012 from expand_deps().
2013 (expand_deps): If we aren't doing second expansion, replace % with
2014 the stem for static pattern rules. Call the new function.
2015 * filedef.h (parse_prereqs): Declare a prototype.
2016 * implicit.c (pattern_search): Initialize the new staticpattern
2017 field.
2018 * main.c (second_expansion): Declare a global variable to remember
2019 if the special target has been seen. Initialize the new
2020 staticpattern field for prerequisites.
2021 * make.h: Extern for second_expansion.
2022 * misc.c (free_dep_chain): New function: frees a struct dep list.
2023 * read.c (read_all_makefiles): Initialize the staticpattern field.
2024 (eval_makefile): Ditto.
2025 (record_files): Check for the .SECONDEXPANSION target and set
2026 second_expansion global if it's found.
2027 Use the new free_dep_chain() instead of doing it by hand.
2028 Set the staticpattern field for prereqs of static pattern targets.
2030 2005-10-16 Paul D. Smith <psmith@gnu.org>
2032 * main.c (main): Set CURDIR to be a file variable instead of a
2033 default, so that values of CURDIR inherited from the environment
2034 won't override the make value.
2036 2005-09-26 Paul D. Smith <psmith@gnu.org>
2038 * job.c (construct_command_argv_internal): If the line is empty
2039 remember to free the temporary argv strings.
2040 Fixes bug # 14527.
2042 2005-09-16 Paul D. Smith <psmith@gnu.org>
2044 * job.c (start_job_command): The noerror flag is a boolean (single
2045 bit); set it appropriately.
2046 Reported by Mark Eichin <eichin@metacarta.com>
2048 2005-08-29 Paul D. Smith <psmith@gnu.org>
2050 * function.c (func_error): On Windows, output from $(info ...)
2051 seems to come in the wrong order. Try to force it with fflush().
2053 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2055 * read.c (record_files): Move code that sets stem for static
2056 pattern rules out of the if (!two_colon) condition so it is
2057 also executed for two-colon rules. Fixes Savannah bug #13881.
2059 2005-08-08 Paul D. Smith <psmith@gnu.org>
2061 * make.h: Don't test that __STDC__ is non-0. Some compilers
2062 (Windows for example) set it to 0 to denote "ISO C + extensions".
2063 Fixes bug # 13594.
2065 2005-08-07 Paul D. Smith <psmith@gnu.org>
2067 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2068 conditional (slightly different version of a fix from Eli).
2070 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2071 If make is running in parallel without -k and two jobs die in a
2072 row, but not too close to each other, then make will quit without
2073 waiting for the rest of the jobs to die.
2075 * main.c (die): Don't reset err before calling reap_children() the
2076 second time: we still want it to be in the error condition.
2077 * job.c (reap_children): Use a static variable, rather than err,
2078 to control whether or not the error message should be printed.
2080 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2082 * w32/subproc/sub_proc.c: Include signal.h.
2083 (process_pipe_io, process_file_io): Pass a pointer to a local
2084 DWORD variable to GetExitCodeProcess. If the exit code is
2085 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2087 * job.c [WINDOWS32]: Include windows.h.
2088 (main_thread) [WINDOWS32]: New global variable.
2089 (reap_children) [WINDOWS32]: Get the handle for the main thread
2090 and store it in main_thread.
2092 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2093 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2094 doing anything else. When we are done, close the main thread
2095 handle and exit with status 130.
2097 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2099 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2100 pointer to fprintf.
2102 * main.c (find_and_set_default_shell): If found a DOSish shell,
2103 set sh_found and the value of default_shell, and report the
2104 findings in debug mode.
2106 * job.c (construct_command_argv_internal): Check unixy_shell, not
2107 no_default_sh_exe, to decide whether to use Unixy or DOSish
2108 builtin commands.
2110 * README.W32: Update with info about the MinGW build.
2112 * build_w32.bat: Support MinGW.
2114 * w32/subproc/build.bat: Likewise.
2116 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2117 printing DWORD args.
2119 * function.c (windows32_openpipe): Fix format strings for printing
2120 DWORD args.
2122 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2123 'reap_mode'.
2124 (start_job_command): Fix format string for printing the result of
2125 process_easy.
2126 (start_job_command) [WINDOWS32]: Do not define.
2127 (exec_command): Fix format string for printing HANDLE args.
2129 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2130 to avoid compiler warnings.
2131 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2132 (Note: some of these fixes were submitted independently by J. Grant)
2134 2005-07-30 J. Grant <jg@jguk.org>
2136 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2137 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2138 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2140 2005-07-15 Paul Smith <psmith@gnu.org>
2142 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2143 we don't have a POSIX shell, then revert to the old
2144 backslash-newline behavior (where they are stripped).
2145 Fixes bug #13665.
2147 2005-07-08 Paul D. Smith <psmith@gnu.org>
2149 * config.h.W32.template: Reorder to match the standard config.h,
2150 for easier comparisons.
2151 From J. Grant <jg@jguk.org>
2153 * maintMakefile: Remove .dep_segment before overwriting it, in
2154 case it's not writable or noclobber is set.
2155 * expand.c (variable_expand_string): Cast result of pointer
2156 arithmetic to avoid a warning.
2157 * main.c (switches): Add full-fledged final initializer.
2159 2005-07-06 Paul D. Smith <psmith@gnu.org>
2161 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2162 * signame.c (strsignal): If we found _sys_siglist[] or
2163 __sys_siglist[] use those instead of sys_siglist[].
2164 From Albert Chin <china@thewrittenword.com>
2166 2005-07-04 Paul D. Smith <psmith@gnu.org>
2168 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2169 globfree(); set up to use the GNU versions.
2170 From Martin Zinser <zinser@zinser.no-ip.info>
2172 2005-07-03 Paul D. Smith <psmith@gnu.org>
2174 From J. Grant <jg@jguk.org>:
2176 * README.W32.template: Update the Windows and tested MSVC versions.
2177 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2178 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2179 * build_w32.bat: Ditto.
2180 * w32/subproc/build.bat: Ditto.
2182 2005-06-28 Paul D. Smith <psmith@gnu.org>
2184 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2185 declaration was checked but not present.
2187 2005-06-27 Paul D. Smith <psmith@gnu.org>
2189 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2190 to unsigned long. Fixes Savannah bug #13550.
2192 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2193 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2194 Fixes Savannah bug #13551.
2196 2005-06-26 Paul D. Smith <psmith@gnu.org>
2198 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2199 it if ANSI_STRING is not set.
2201 2005-06-25 Paul D. Smith <psmith@gnu.org>
2203 * read.c (eval): If no filenames are passed to any of the
2204 "include" variants, don't print an error.
2205 * doc/make.texi (Include): Document this.
2206 Fixes Savannah bug #1761.
2208 * job.c (construct_command_argv_internal): Sanitize handling of
2209 backslash/newline pairs according to POSIX: that is, keep the
2210 backslash-newline in the command script, but remove a following
2211 TAB character, if present. In the fast path, make sure that the
2212 behavior matches what the shell would do both inside and outside
2213 of quotes. In the slow path, quote the backslash and put a
2214 literal newline in the string.
2215 Fixes Savannah bug #1332.
2216 * doc/make.texi (Execution): Document the new behavior and give
2217 some examples.
2218 * NEWS: Make a note of the new behavior.
2220 * make.h [WINDOWS32]: #include <direct.h>.
2221 Fixes Savannah bug #13478.
2223 * remake.c (name_mtime): If the stat() of a file fails and the -L
2224 option was given and the file is a symlink, take the best mtime of
2225 the symlink we can get as the mtime of the file and don't fail.
2226 Fixes Savannah bug #13280.
2228 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2229 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2230 inside a variable reference. Make this function static as it's
2231 only used here.
2232 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2233 parsing an unexpanded line looking for semicolons.
2234 Fixes Savannah bug #1454.
2235 * misc.c (remove_comments): Move this to read.c and make it static
2236 as it's only used there. Call find_char_unquote() with new arg.
2237 * make.h: Remove prototypes for find_char_unquote() and
2238 remove_comments() since they're static now.
2240 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2241 its export flag and obtain its value. When we need to re-exec,
2242 increment the value and add it into the environment.
2243 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2244 * NEWS: Mention MAKE_RESTARTS.
2245 * main.c (always_make_set): New variable. Change the -B option to
2246 set this one instead.
2247 (main): When checking makefiles, only set always_make_flag if
2248 always_make_set is set AND the restarts flag is 0. When building
2249 normal targets, set it IFF always_make_set is set.
2250 (main): Avoid infinite recursion with -W, too: only set what-if
2251 files to NEW before we check makefiles if we've never restarted
2252 before. If we have restarted, set what-if files to NEW _after_ we
2253 check makefiles.
2254 Fixes Savannah bug #7566:
2256 2005-06-17 Paul D. Smith <psmith@gnu.org>
2258 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2259 in the prerequisites list.
2261 2005-06-12 Paul D. Smith <psmith@gnu.org>
2263 Fix Savannah bug # 1328.
2265 * configure.in: Check for atexit().
2266 * misc.c (close_stdout): Test stdout to see if writes to it have
2267 failed. If so, be sure to exit with a non-0 error code. Based on
2268 code found in gnulib.
2269 * make.h: Prototype.
2270 * main.c (main): Install close_stdout() with atexit().
2272 2005-06-10 Paul D. Smith <psmith@gnu.org>
2274 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2276 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2277 headers; make vmsWaitForChildren() static; extern vmsify().
2278 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2279 Don't create child_execute_job() here (it's in vmsjobs.c).
2280 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2282 2005-06-09 Paul D. Smith <psmith@gnu.org>
2284 * variable.c (push_new_variable_scope): File variables point
2285 directly to the global_setlist variable. So, inserting a new
2286 scope in front of that has no effect on those variables: they
2287 don't go through current_variable_set_list. If we're pushing a
2288 scope and the current scope is global, push it "the other way" so
2289 that the new setlist is in the global_setlist variable, and
2290 next points to a new setlist with the global variable set.
2291 (pop_variable_scope): Properly undo a push with the new
2292 semantics.
2293 Fixes Savannah bug #11913.
2295 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2297 * job.c (reap_children): Don't die of the command failed but
2298 the dontcare flag is set. Fixes Savannah bug #13216.
2300 * implicit.c (pattern_search): When creating a target from
2301 an implicit rule match, lookup pattern target and set precious
2302 flag in a newly created target. Fixes Savannah bug #13218.
2304 2005-05-13 Paul D. Smith <psmith@gnu.org>
2306 Implement "if... else if... endif" syntax.
2308 * read.c (eval): Push all checks for conditional words ("ifeq",
2309 "else", etc.) down into the conditional_line() function.
2310 (conditional_line): Rework to allow "else if..." clause. New
2311 return value -2 for lines which are not conditionals. The
2312 ignoring flag can now also be 2, which means "already parsed a
2313 true branch". If that value is seen no other branch of this
2314 conditional can be considered true. In the else parsing if there
2315 is extra text after the else, invoke conditional_line()
2316 recursively to see if it's another conditional. If not, it's an
2317 error. If so, raise the conditional value to this level instead
2318 of creating a new conditional nesting level. Special check for
2319 "else" and "endif", which aren't allowed on the "else" line.
2320 * doc/make.texi (Conditional Syntax): Document the new syntax.
2322 2005-05-09 Paul D. Smith <psmith@gnu.org>
2324 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2325 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2326 recurses to the w32 directory, even on non-Windows systems. Use
2327 the method suggested in the automake manual.
2328 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2329 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2331 2005-05-07 Paul D. Smith <psmith@gnu.org>
2333 * main.c (die): If we're dying with a fatal error (not that a
2334 command has failed), write back any leftover tokens before we go.
2336 * job.c (set_child_handler_action_flags): If there are jobs
2337 waiting for the load to go down, set an alarm to go off in 1
2338 second. This allows us to wake up from a potentially long-lasting
2339 read() and start a new job if the load has gone down. Turn it off
2340 after the read.
2341 (job_noop): Dummy signal handler function.
2342 (new_job): Invoke it with the new semantics.
2344 * docs/make.texi: Document secondary expansion. Various cleanups
2345 and random work.
2347 2005-05-03 Paul D. Smith <psmith@gnu.org>
2349 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2350 the targets which are to ultimately be made are called "goals";
2351 see the GNU make manual. Also, MAKECMDGOALS, etc.
2353 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2354 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2355 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2357 2005-05-02 Paul D. Smith <psmith@gnu.org>
2359 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2360 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2361 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2362 functions to vmsjobs.c. #include it into jobs.c.
2364 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2365 jobserver tokens. I found that this happens when an exported
2366 recursive variable contains a $(shell ...) function reference: in
2367 this situation we could "forget" to write back a token.
2369 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2370 we have. It's not reliable to depend on the number of children in
2371 our linked list so keep a separate count.
2372 (new_job): Check jobserver_tokens rather than children &&
2373 waiting_jobs. Increment jobserver_tokens when we get one.
2374 (free_child): If jobserver_tokens is 0, internal error. If it's
2375 >1, write a token back to the jobserver pipe (we don't write a
2376 token for the "free" job). Decrement jobserver_tokens.
2378 * main.c: Add variable master_job_slots.
2379 (main): Set it to hold the number of jobs requested if we're the
2380 master process, when using the jobserver.
2381 (die): Sanity checks: first test jobserver_tokens to make sure
2382 this process isn't holding any tokens we didn't write back.
2383 Second, if master_job_slots is set count the tokens left in the
2384 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2386 2005-04-24 Paul D. Smith <psmith@gnu.org>
2388 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2389 with -l# can lose jobserver tokens, because waiting jobs are not
2390 consulted properly when checking for the "free" token.
2392 * job.c (free_child): Count waiting_jobs as having tokens.
2393 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2394 handle jobs waiting for the load to drop.
2396 2005-04-23 Paul D. Smith <psmith@gnu.org>
2398 * main.c (main): Be careful to not core if a variable setting in
2399 the environment doesn't contain an '='. This is illegal but can
2400 happen in broken setups.
2401 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2403 2005-04-12 Paul D. Smith <psmith@gnu.org>
2405 The second expansion feature causes significant slowdown. Timing
2406 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2407 read the makefile before the feature, to 11+s to do the same
2408 operations after the feature. Additionally, memory usage
2409 increased drastically. To fix this I added some intelligence that
2410 avoids the overhead of the second expansion unless it's required.
2412 * dep.h: Add a new boolean field, need_2nd_expansion.
2414 * read.c (eval): When creating the struct dep for the target,
2415 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2416 (record_files): If there's a "%" in a static pattern rule, it gets
2417 converted to "$*" so set need_2nd_expansion to 1.
2419 * file.c (expand_deps): Rework to be more efficient. Only perform
2420 initialize_file_variables(), set_file_variables(), and
2421 variable_expand_for_file() if the need_2nd_expansion is set.
2423 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2424 (pattern_search): Ditto.
2425 * main.c (handle_non_switch_argument): Ditto.
2426 (main): Ditto.
2427 * read.c (read_all_makefiles): Ditto.
2428 (eval_makefile): Ditto.
2430 2005-04-07 Paul D. Smith <psmith@gnu.org>
2432 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2433 * variable.c (sync_Path_environment): Ditto.
2434 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2436 * main.c (main): Define the .FEATURES variable.
2437 * NEWS: Announce .FEATURES.
2438 * doc/make.texi (Special Variables): Document .FEATURES.
2440 * remake.c (check_dep): If a file is .PHONY, update it even if
2441 it's marked intermediate. Fixes Savannah bug #12331.
2443 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2445 * file.c (expand_deps): Factor out the second expansion and
2446 prerequisite line parsing logic from snap_deps().
2448 * file.c (snap_deps): Use expand_deps(). Expand and parse
2449 prerequisites of the .SUFFIXES special target first. Fixes
2450 Savannah bug #12320.
2452 2005-03-13 Paul D. Smith <psmith@gnu.org>
2454 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2455 Zaretskii.
2457 2005-03-11 Paul D. Smith <psmith@gnu.org>
2459 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2460 available, not undefined (from Earnie Boyd).
2462 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2464 * implicit.c (pattern_search): Mark an intermediate target as
2465 precious if it happened to be a prerequisite of some (other)
2466 target. Fixes Savannah bug #12267.
2468 2005-03-09 Paul D. Smith <psmith@gnu.org>
2470 * read.c (eval_makefile): Add alloca(0).
2471 (eval_buffer): Ditto.
2473 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2475 * main.c (main): Use o_file instead of o_default when defining
2476 the .DEFAULT_TARGET special variable.
2477 * read.c (eval): Use define_variable_global() instead of
2478 define_variable() when setting new value for the .DEFAULT_TARGET
2479 special variable. Fixes Savannah bug #12266.
2481 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2483 * imlicit.c (pattern_search): Mark files for which an implicit
2484 rule has been found as targets. Fixes Savannah bug #12202.
2486 2005-03-04 Paul D. Smith <psmith@gnu.org>
2488 * AUTHORS: Update.
2489 * doc/make.texi (Automatic Variables): Document $|.
2491 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2493 * read.c (record_files): Instead of substituting % with
2494 actual stem value in dependency list replace it with $*.
2495 This fixes stem triple expansion bug.
2497 * implicit.c (pattern_search): Copy stem to a separate
2498 buffer and make it a properly terminated string. Assign
2499 this buffer instead of STEM (which is not terminated) to
2500 f->stem. Instead of substituting % with actual stem value
2501 in dependency list replace it with $*. This fixes stem
2502 triple expansion bug.
2504 2005-03-01 Paul D. Smith <psmith@gnu.org>
2506 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2507 on Windows, as it takes a handle not a pid. Just exit.
2508 Fix from patch #3679, provided by Alessandro Vesely.
2510 * configure.in: Update check for sys_siglist[] from autoconf manual.
2511 * signame.c (strsignal): Update to use the new autoconf macro.
2513 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2515 * read.c (record_files): Add a check for the list of prerequisites
2516 of a static pattern rule being empty. Fixes Savannah bug #12180.
2518 2005-02-28 Paul D. Smith <psmith@gnu.org>
2520 * doc/make.texi (Text Functions): Update docs to allow the end
2521 ordinal for $(wordlist ...) to be 0.
2522 * function.c (func_wordlist): Fail if the start ordinal for
2523 $(wordlist ...) is <1. Matches documentation.
2524 Resolves Savannah support request #103195.
2526 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2527 previously we were stopping when !-q, exactly the opposite. This
2528 has been wrong since version 1.34, in 1994!
2529 (update_file): If we got an error don't break out to run more
2530 double-colon rules: just return immediately.
2531 Fixes Savannah bug #7144.
2533 2005-02-27 Paul D. Smith <psmith@gnu.org>
2535 * misc.c (end_of_token): Make argument const.
2536 * make.h: Update prototype.
2538 * function.c (abspath, func_realpath, func_abspath): Use
2539 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2540 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2541 * read.c (record_files): Ditto.
2542 * variable.c (do_variable_definition): Ditto.
2544 * function.c (func_error): Create a new function $(info ...) that
2545 simply prints the message to stdout with no extras.
2546 (function_table_init): Add new function to the table.
2547 * NEWS: Add $(info ...) reference.
2548 * doc/make.texi (Make Control Functions): Document it.
2550 New feature: if the system supports symbolic links, and the user
2551 provides the -L/--check-symlink-time flag, then use the latest
2552 mtime between the symlink(s) and the target file.
2554 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2555 readlink(). If both are available, define MAKE_SYMLINKS.
2556 * main.c: New variable: check_symlink_flag.
2557 (usage): Add a line for -L/--check-symlink-times to the help string.
2558 (switches): Add -L/--check-symlink-times command line argument.
2559 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2560 print a warning and disable it again.
2561 * make.h: Declare check_symlink_flag.
2562 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2563 if the file is a symlink then check each link in the chain and
2564 choose the NEWEST mtime we find as the mtime for the file. The
2565 newest mtime might be the file itself!
2566 * NEWS: Add information about this new feature.
2567 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2569 Avoid core dumps described in Savannah bug # 12124:
2571 * file.c: New variable snapped_deps remember whether we've run
2572 snap_deps().
2573 (snap_deps): Set it.
2574 * filedef.h: Extern it.
2575 * read.c (record_files): Check snapped_deps; if it's set then
2576 we're trying to eval a new target/prerequisite relationship from
2577 within a command script, which we don't support. Fatal.
2579 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2581 Implementation of the .DEFAULT_TARGET special variable.
2583 * read.c (eval): If necessary, update default_target_name when
2584 reading rules.
2585 * read.c (record_files): Update default_target_file if
2586 default_target_name has changed.
2587 * main.c (default_target_name): Define.
2588 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2589 default_target_name is set use default_target_file as a root
2590 target to make.
2591 * filedef.h (default_target_name): Declare.
2592 * dep.h (free_dep_chain):
2593 * misc.c (free_dep_chain): Change to operate on struct nameseq
2594 and change name to free_ns_chain.
2595 * file.c (snap_deps): Update to use free_ns_chain.
2597 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2599 Implementation of the second expansion in explicit rules,
2600 static pattern rules and implicit rules.
2602 * read.c (eval): Refrain from chopping up rule's dependencies.
2603 Store them in a struct dep as a single dependency line. Remove
2604 the code that implements SySV-style automatic variables.
2606 * read.c (record_files): Adjust the code that handles static
2607 pattern rules to expand all percents instead of only the first
2608 one. Reverse the order in which dependencies are stored so that
2609 when the second expansion reverses them again they appear in
2610 the makefile order (with some exceptions, see comments in
2611 the code). Remove the code that implements SySV-style automatic
2612 variables.
2614 * file.c (snap_deps): Implement the second expansion and chopping
2615 of dependency lines for explicit rules.
2617 * implicit.c (struct idep): Define an auxiliary data type to hold
2618 implicit rule's dependencies after stem substitution and
2619 expansion.
2621 * implicit.c (free_idep_chain): Implement.
2623 * implicit.c (get_next_word): Implement helper function for
2624 parsing implicit rule's dependency lines into words taking
2625 into account variable expansion requests. Used in the stem
2626 splitting code.
2628 * implicit.c (pattern_search): Implement the second expansion
2629 for implicit rules. Also fixes bug #12091.
2631 * commands.h (set_file_variables): Declare.
2632 * commands.c (set_file_variables): Remove static specifier.
2634 * dep.h (free_dep_chain): Declare.
2635 * misc.c (free_dep_chain): Implement.
2637 * variable.h (variable_expand_for_file): Declare.
2638 * expand.c (variable_expand_for_file): Remove static specifier.
2640 * make.h (strip_whitespace): Declare.
2641 * function.c (strip_whitespace): Remove static specifier.
2643 2005-02-26 Paul D. Smith <psmith@gnu.org>
2645 * main.c (main): Check for ferror() when reading makefiles from stdin.
2646 Apparently some shells in Windows don't close pipes properly and
2647 require this check.
2649 2005-02-24 Jonathan Grant <jg@jguk.org>
2651 * configure.in: Add MinGW configuration options, and extra w32 code
2652 directory.
2653 * Makefile.am: Add MinGW configuration options, and extra w32 code
2654 directory.
2655 * main.c: Determine correct program string (after last \ without .exe).
2656 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2657 type fix x2
2658 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2659 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2660 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2661 environment support.
2663 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2665 * function.c (func_shell): When initializing error_prefix, check
2666 that reading file name is not null. This fixes long-standing
2667 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2669 2005-02-09 Paul D. Smith <psmith@gnu.org>
2671 * maintMakefile: Update the CVS download URL to simplify them.
2672 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2673 downloading the .texi files from Savannah now.
2675 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2677 * main.c (handle_non_switch_argument): Only add variables to
2678 command_variables if they're not already there: duplicate settings
2679 waste space and can be confusing to read.
2681 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2682 this header is never included by non-WINDOWS32 code, and it
2683 requires <config.h> to define which isn't always included first.
2685 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2686 testing MINGW32 versions.
2688 * main.c (log_working_directory): flush stdout to be sure the WD
2689 change is printed before any stderr messages show up.
2691 2005-02-01 Paul D. Smith <psmith@gnu.org>
2693 * maintMakefile (po_repo): Update the GNU translation site URL.
2695 2004-12-01 Paul D. Smith <psmith@gnu.org>
2697 * main.c (main): Change char* env_shell to struct variable shell_var.
2698 * variable.c (target_environment): Use new shell_var.
2700 2004-11-30 Paul D. Smith <psmith@gnu.org>
2702 * configure.in: The old way we avoided creating build.sh from
2703 build.sh.in before build.sh.in exists doesn't work anymore; we
2704 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2705 the help!). This also keeps automake from complaining.
2706 * Makefile.am (README): Add a dummy target so automake won't
2707 complain that this file doesn't exist when we checkout from CVS.
2708 * maintMakefile (.dep_segment): Rewrite this rule since newer
2709 versions of automake don't provide DEP_FILES.
2711 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2713 Implementation of `realpath' and `abspath' built-in functions.
2715 * configure.in: Check for realpath.
2716 * function.c (abspath): Return an absolute file name that does
2717 not contain any `.' or `..' components, nor repeated `/'.
2718 * function.c (func_abspath): For each name call abspath.
2719 * function.c (func_realpath): For each name call realpath
2720 from libc or delegate to abspath if realpath is not available.
2721 * doc/make.texi (Functions for File Names): Document new functions.
2722 * doc/make.texi (Quick Reference): Ditto.
2724 2004-11-28 Paul D. Smith <psmith@gnu.org>
2726 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2727 arguments. Fixes bug #10252.
2729 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2731 * main.c (main): Set SHELL to v_noexport by default. Remember the
2732 original environment setting of SHELL in the env_shell variable.
2733 * main.h: Export new env_shell variable.
2734 * variable.c (target_environment): If we find a v_noexport
2735 variable for SHELL, add a SHELL variable with the env_shell value.
2736 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2737 * doc/make.texi (Variables/Recursion): Ditto.
2739 2004-11-28 Paul D. Smith <psmith@gnu.org>
2741 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2742 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2743 Patch by Alessandro Vesely.
2745 2004-11-12 Paul D. Smith <psmith@gnu.org>
2747 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2748 the command line if it's inside a string.
2749 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2751 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2753 * function.c (func_lastword): New function: return last word
2754 from the list of words.
2755 * doc/make.texi: Document $(lastword ). Fix broken links in
2756 Quick Reference section.
2758 2004-10-06 Paul D. Smith <psmith@gnu.org>
2760 Apply patch from Alessandro Vesely, provided with bug # 9748.
2761 Fix use of tmpnam() to work with Borland C.
2763 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2764 construction of a temporary filename, and call new function
2765 create_batch_filename().
2766 (create_batch_filename) [WINDOWS32]: New function to create a
2767 temporary filename.
2769 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2771 * read.c (record_target_var): Expand simple pattern-specific
2772 variable.
2773 * variable.c (initialize_file_variables): Do not expand simple
2774 pattern-specific variable.
2776 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2778 * remake.c (update_file_1): When rebuilding makefiles inherit
2779 dontcare flag from a target that triggered update.
2781 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2783 * variable.c (initialize_file_variables): Mark pattern-specific
2784 variable as a per-target and copy export status.
2786 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2788 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2790 * implicit.c (pattern_search): When considering an implicit rule's
2791 prerequisite check that it is actually a target rather then
2792 just an entry in the file hashtable.
2794 2004-09-21 Paul D. Smith <psmith@gnu.org>
2796 * read.c (readstring): Fix some logic errors in backslash handling.
2797 (eval): Remove some unnecessary processing in buffer handling.
2798 (record_target_var): Assert that parse_variable_definition() succeeded.
2799 Reported by: Markus Mauhart <qwe123@chello.at>.
2801 * misc.c: Removed the sindex() function. All instances of this
2802 function were trivially replaceable by the standard strstr()
2803 function, and that function will always have better (or certainly
2804 no worse) performance than the very simple-minded algorithm
2805 sindex() used. This can matter with complex makefiles.
2806 * make.h: Remove the prototype for sindex().
2807 * function.c (subst_expand): Convert sindex() call to strstr().
2808 This means we no longer need to track the TLEN value so remove that.
2809 (func_findstring): Convert sindex() to strstr().
2810 * commands.c (chop_commands): Convert sindex() calls to strstr().
2811 Suggested by: Markus Mauhart <qwe123@chello.at>.
2813 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2814 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2815 If SHELL is set to CMD.EXE then assume it's batch-mode and
2816 non-unixy. I wrote the code differently from the patch, though,
2817 to make it safer. This also resolves bug #9174.
2819 2004-09-20 Paul D. Smith <psmith@gnu.org>
2821 * expand.c (variable_expand_string): Modify to invoke
2822 patsubst_expand() instead of subst_expand(); the latter didn't
2823 handle suffix patterns correctly.
2824 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2825 was used only from variable_expand_string() and is no longer used
2826 there.
2827 (func_subst): Ditto, on call to subst_expand().
2828 (patsubst_expand): Require the percent pointers to point to the
2829 character after the %, not to the % itself.
2830 * read.c (record_files): New call criteria for patsubst_expand().
2831 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2832 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2834 2004-09-19 Paul D. Smith <psmith@gnu.org>
2836 * function.c (subst_expand): Fix a check in by_word: look for a
2837 previous blank if we're beyond the beginning of the string, not
2838 the beginning of the word.
2839 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2841 2004-05-16 Paul D. Smith <psmith@gnu.org>
2843 * remake.c (update_goal_chain): Change the argument specifying
2844 whether we're rebuilding makefiles to be a global variable,
2845 REBUILDING_MAKEFILES.
2846 (complain): Extract the code that complains about no rules to make
2847 a target into a separate function.
2848 (update_file_1): If we tried to rebuild a file during the makefile
2849 rebuild phase and it was dontcare, then no message was printed.
2850 If we then try to build the same file during the normal build,
2851 print a message this time.
2852 (remake_file): Don't complain about un-remake-able files when
2853 we're rebuilding makefiles.
2855 2004-05-11 Paul D. Smith <psmith@gnu.org>
2857 * job.c (construct_command_argv_internal): OS/2 patches from
2858 Andreas Buening <andreas.buening@nexgo.de>.
2860 2004-05-10 Paul D. Smith <psmith@gnu.org>
2862 * remake.c (update_file): Don't walk the double-colon chain unless
2863 this is a double-colon rule. Fix suggested by Boris Kolpackov
2864 <boris@kolpackov.net>.
2866 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2867 * readme.vms: New section describing OpenVMS support and issues.
2868 * default.c (default_variables): Add support for IA64.
2869 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2870 without some privilege aborts make with the error
2871 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2872 pressing Ctrl+Y and the input device is no terminal. The change
2873 catches this error and just continues.
2875 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2877 2004-04-25 Paul D. Smith <psmith@gnu.org>
2879 * commands.c (set_file_variables): Set $< properly in the face of
2880 order-only prerequisites.
2881 Patch from Boris Kolpackov <boris@kolpackov.net>
2883 2004-04-21 Bob Byrnes <byrnes@curl.com>
2885 * main.c (main): Notice failures to remake makefiles.
2887 2004-03-28 Paul D. Smith <psmith@gnu.org>
2889 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2891 * job.c: No default shell for RISC OS.
2892 (load_too_high): Hard-code the return to 1.
2893 (construct_command_argv_internal): No sh_chars or sh_cmds.
2894 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2896 2004-03-20 Paul D. Smith <psmith@gnu.org>
2898 * variable.c (do_variable_definition): Don't append from the
2899 global set if a previous non-appending target-specific variable
2900 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2901 (with fix).
2903 * expand.c (reference_variable): Don't give up on variables with
2904 no value that have the target-specific append flag set: they might
2905 have a value after all. Reported by Oliver Schmidt
2906 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2907 <nikulin@dx1cmd.inp.nsk.su>.
2909 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2910 refer to absolute pathnames in directories that don't exist: some
2911 portion of the makefile could create those directories before we
2912 match the pattern. Fixes bugs #775 and #108.
2914 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2916 * main.c (main): Free makefile_mtimes if we have any.
2917 * README.W32.template: Update documentation for the current status
2918 of the MS-Windows port.
2919 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2920 environment variable is sometimes already defined which causes the
2921 build to fail.
2922 * main.c (debug_signal_handler): Only define this function if
2923 SIGUSR1 is available.
2925 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2927 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2928 * README.OS2.template: Documentation updates.
2929 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2930 link line for safety.
2931 * maintMakefile (build.sh.in): Remove an extraneous ")".
2932 * job.c (child_execute_job): Close saved FDs.
2933 * job.c (exec_command) [OS/2]: exec_command(): If the command
2934 can't be exec'ed and if the shell is not Unix-sh, then try again
2935 with argv = { "cmd", "/c", ... }. Normally, this code is never
2936 reached for the cmd shell unless the command really doesn't exist.
2937 (construct_command_argv_internal) [OS/2]: The code for cmd
2938 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2939 The CMD builtin commands are case insensitive so use strcasecmp().
2941 2004-03-19 Paul D. Smith <psmith@gnu.org>
2943 * read.c (do_define): Re-order line counter increment so the count
2944 is accurate (we were losing one line per define). Reported by
2945 Dave Yost <Dave@Yost.com>.
2947 2004-03-06 Paul D. Smith <psmith@gnu.org>
2949 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2950 compiler.
2951 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2952 * misc.c (message,error,fatal): Ditto.
2953 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2954 * config.h.W32.template: Ditto.
2955 * config.h-vms.template: Ditto.
2956 * config.ami.template: Ditto.
2958 2004-03-04 Paul D. Smith <psmith@gnu.org>
2960 * README.template: Add a note about broken /bin/sh on SunOS
2961 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2963 * misc.c (message, error, fatal): Don't use "..." if we're using
2964 varargs. ansi2knr should handle this but it doesn't work: it
2965 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2966 done. On many systems (SunOS for example) va_dcl is a #define.
2967 So, force the use of the non-"..." version on pre-ANSI compilers.
2969 * maintMakefile (sign-dist): Create some rules to help automate
2970 the new GNU ftp upload method.
2972 2004-02-24 Paul D. Smith <psmith@gnu.org>
2974 * config.h.W32.template: Add HAVE_STDARG_H
2975 * config.h-vms.template: Ditto.
2976 * config.ami.template: Ditto.
2978 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2980 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2981 * build_w32.bat: Remove extra "+".
2983 2004-02-23 Paul D. Smith <psmith@gnu.org>
2985 * make.h: Create an UNUSED macro to mark unused parameters.
2986 * (many): Clean up warnings by applying UNUSED, fixing
2987 signed/unsigned incompatibilities, etc.
2989 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2990 autoconf warnings.
2991 * filedef.h: Name the command_state enumeration.
2992 * file.c (set_command_state): Use the enumeration in the function
2993 argument.
2995 * configure.in: Explicitly set SET_MAKE to empty, to disable
2996 MAKE=make even when no make already exists. Fix bug #3823.
2998 2004-02-22 Paul D. Smith <psmith@gnu.org>
3000 * maintMakefile: Perl script to clean up all non-CVS files. Use
3001 it on all the subdirectories for the cvs-clean target.
3003 * main.c (decode_switches): Require non-empty strings for all our
3004 string command-line options. Fixes Debian bug # 164165.
3006 * configure.in: Check for stdarg.h and varargs.h.
3007 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3008 for printing messages.
3009 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3010 (message): Ditto.
3011 (error): Ditto.
3012 (fatal): Ditto.
3014 A number of patches for OS/2 support from Andreas Buening
3015 <andreas.buening@nexgo.de>:
3017 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3018 disable the SIGCHLD handler.
3019 (reap_children) [OS/2]: Remove special handling of job_rfd.
3020 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3021 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3022 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3023 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3024 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3025 systems.
3027 2004-02-21 Paul D. Smith <psmith@gnu.org>
3029 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3030 <mail@kristov.de> reports that if process_begin() fails we don't
3031 handle the error condition correctly in all cases.
3032 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3033 to have a newline on the message.
3035 * job.c (construct_command_argv_internal): Add "test" to UNIX
3036 sh_cmds[]. Fixes Savannah bug # 7606.
3038 2004-02-04 Paul D. Smith <psmith@gnu.org>
3040 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3041 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3042 Hartmut Becker <Hartmut.Becker@hp.com>.
3044 2004-01-21 Paul D. Smith <psmith@gnu.org>
3046 * job.c (load_too_high): Implement an algorithm to control the
3047 "thundering herd" problem when using -l to control job creation
3048 via the load average. The system only recomputes the load once a
3049 second but we can start many jobs in a second. To solve this we
3050 keep track of the number of jobs started in the last second and
3051 apply a weight to try to guess what a correct load would be.
3052 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3053 Also fixes bug #4693.
3054 (reap_children): Decrease the job count for this second.
3055 (start_job_command): Increase the job count for this second.
3057 * read.c (conditional_line): Expand the text after ifn?def before
3058 checking to see if it's a single word. Fixes bug #7257.
3060 2004-01-09 Paul D. Smith <psmith@gnu.org>
3062 * file.c (print_file): Recurse to print all targets in
3063 double-colon rules. Fixes bug #4518, reported (with patch) by
3064 Andrew Chatham <chatham@google.com>.
3066 2004-01-07 Paul D. Smith <psmith@gnu.org>
3068 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3069 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3070 AC_FUNC_SETVBUF_REVERSED.
3072 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3073 (MAKE Variable): Fix Savannah bug #4898.
3075 * job.c (construct_command_argv_internal): Add "!" to the list of
3076 shell escape chars. POSIX sh allows it to appear before a
3077 command, to negate the exit code. Fixes bug #6404.
3079 * implicit.c (pattern_search): When matching an implicit rule,
3080 remember which dependencies have the ignore_mtime flag set.
3081 Original fix provided in Savannah patch #2349, by Benoit
3082 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3084 2003-11-22 Paul D. Smith <psmith@gnu.org>
3086 * README.W32.template (Outputs): Clarification on -j with
3087 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3088 <jg-make@jguk.org>.
3090 2003-11-02 Paul D. Smith <psmith@gnu.org>
3092 * function.c (func_if): Strip all the trailing whitespace from the
3093 condition, then don't expand it. Fixed bug # 5798.
3095 * expand.c (recursively_expand_for_file): If we're expanding a
3096 variable with no file context, then use the variable's context.
3097 Fixes bug # 6195.
3099 2003-10-21 Paul D. Smith <psmith@gnu.org>
3101 * main.c (log_working_directory): Add newlines to printf()s.
3103 * README.cvs: Add a note to ignore warnings during autoreconf.
3105 * maintMakefile (po_repo): Set a new URL for PO file updates.
3106 (get-config/config.guess get-config/config.sub): Get these files
3107 from the Savannah config project instead of ftp.gnu.org.
3109 2003-10-05 Paul Eggert <eggert@twinsun.com>
3111 * main.c (main): Avoid potential subscript error if environ has
3112 short strings.
3114 2003-08-22 Paul D. Smith <psmith@gnu.org>
3116 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3117 systems which don't yet implement the C89 standard :-/.
3119 2003-07-18 Paul D. Smith <psmith@gnu.org>
3121 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3122 [WINDOWS32]: Initialize hash.
3124 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3126 * dir.c (read_dirstream): Provide a workaround for broken versions of
3127 the MinGW dirent structure.
3129 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3131 * w32/include/dirent.h: Add __MINGW32__ filter.
3133 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3135 * make.h: Add global declaration of *make_host.
3136 * main.c (print_usage): Remove local declaration of *make_host.
3137 (print_version): Display "This program built for ..." after Copyright
3138 notice.
3140 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3142 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3143 execution of "makeinfo --html make.texi".
3145 2003-04-30 Paul D. Smith <psmith@gnu.org>
3147 * build.template: Make some changes to maybe allow this script to
3148 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3150 * README.OS2.template: New file for OS/2 support. Original
3151 contributed by Andreas Buening.
3152 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3153 DOS-style paths.
3155 2003-04-19 Paul D. Smith <psmith@gnu.org>
3157 Fix bug #1405: allow a target to match multiple pattern-specific
3158 variables.
3160 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3161 variable.c, where they've always belonged.
3162 * rule.h: Move the prototypes and struct pattern_var as well.
3163 * variable.c (initialize_file_variables): Invoke
3164 lookup_pattern_var() in a loop, until no more matches are found.
3165 If a match is found, create a new variable set for the target's
3166 pattern variables. Then merge the contents of each matching
3167 pattern variable set into the target's pattern variable set.
3168 (lookup_pattern_var): Change this function to be usable
3169 in a loop. It takes a starting position: if NULL, start at the
3170 beginning; if non-NULL, start with the pattern variable after that
3171 position, and return the next matching pattern.
3172 (create_pattern_var): Create a unique instance of
3173 pattern-specific variables for every definition in the makefile.
3174 Don't combine the same pattern together. This allows us to
3175 process the variable handling properly even when the same pattern
3176 is used multiple times.
3177 (parse_variable_definition): New function: break out the parsing
3178 of a variable definition line from try_variable_definition.
3179 (try_variable_definition): Call parse_variable_definition to
3180 parse.
3181 (print_variable_data_base): Print out pattern-specific variables.
3182 * variable.h (struct variable): Remember when a variable is
3183 conditional. Also remember its flavor.
3184 (struct pattern_var): Instead of keeping a variable set, we just
3185 keep a single variable for each pattern.
3186 * read.c (record_target_var): Each pattern variable contains only a
3187 single variable, not a set, so create it properly.
3188 * doc/make.texi (Pattern-specific): Document the new behavior.
3190 2003-04-17 Paul D. Smith <psmith@gnu.org>
3192 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3193 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3194 file/directory naming rules for VMS so I can't tell whether this
3195 is correct or not.
3197 2003-04-09 Paul D. Smith <psmith@gnu.org>
3199 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3200 DOS-style pathnames: backslash separators and drive specifiers.
3202 2003-03-28 Paul D. Smith <psmith@gnu.org>
3204 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3205 the intermediate flag on all targets. Fixes bug #2515.
3207 2003-03-24 Paul D. Smith <psmith@gnu.org>
3209 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3210 Upgrade to autoconf 2.57 and automake 1.7.3.
3212 * job.c: More OS/2 changes from Andreas Buening.
3214 * file.c (print_file): Fix variable initialization.
3215 Fixes bug #2892.
3217 * remake.c (notice_finished_file):
3219 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3220 some calls (like readdir()) return NULL in valid situations
3221 without resetting errno. Fixes bug #2846.
3223 2003-02-25 Paul D. Smith <psmith@gnu.org>
3225 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3227 * job.c (_is_unixy_shell) [OS/2]: New function.
3228 Set default shell to /bin/sh.
3229 (reap_children): Close the job_rfd pipe here since we don't use a
3230 SIGCHLD handler.
3231 (set_child_handler_action_flags): define this to empty on OS/2.
3232 (start_job_command): Close the jobserver pipe and use
3233 child_execute_job() instead of fork/exec.
3234 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3235 rather than exec'ing, then reconfigure stdin/stdout.
3236 (exec_command): Rewrite to use spawn instead of exec. Return the
3237 PID of the child.
3239 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3240 in DOS. Handle the TEMP environment variable as in DOS. Don't
3241 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3242 use -j in DOS mode. Use child_execute_job() instead of
3243 exec_command().
3245 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3246 spawn() instead.
3248 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3249 prototypes that return values.
3251 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3253 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3254 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3255 for OS/2.
3256 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3257 DOS paths.
3259 2003-02-24 Paul D. Smith <psmith@gnu.org>
3261 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3262 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3263 (child_execute_job) [VMS]: Handle error status properly.
3264 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3266 * function.c (func_shell): Use EINTRLOOP() while reading from the
3267 subshell pipe (Fixes bug #2502).
3268 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3269 jobserver pipe.
3270 * main.c (main): Ditto.
3272 2003-01-30 Paul D. Smith <psmith@gnu.org>
3274 * read.c (eval): eval() was not fully reentrant, because the
3275 collapsed buffer was static. Change it to be an automatic
3276 variable so that eval() can be invoked recursively.
3277 Fixes bug # 2238.
3278 (eval): Apply patch # 1022: fix memory reference error on long
3279 target-specific variable lines.
3280 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3282 * function.c (check_numeric): Combine the is_numeric() function
3283 into this function, since it's only called from one place.
3284 Constify this function. Have it print the incorrect string in the
3285 error message. Fixes bug #2407.
3286 (strip_whitespace): Constify.
3287 (func_if): Constify.
3288 * expand.c (expand_argument): Constify.
3290 2003-01-29 Paul D. Smith <psmith@gnu.org>
3292 Fix bug # 2169, also reported by other people on various systems.
3294 * make.h: Some systems, such as Solaris and PTX, do not fully
3295 implement POSIX-compliant SA_RESTART functionality; important
3296 system calls like stat() and readdir() can still fail with EINTR
3297 even if SA_RESTART has been set on the signal handler. So,
3298 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3299 EINTR for system calls which return -1 or 0 (NULL), respectively,
3300 on error.
3301 Also, remove the old atomic_stat()/atomic_readdir() and
3302 HAVE_BROKEN_RESTART handling.
3304 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3306 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3307 * remake.c (touch_file): Ditto.
3309 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3310 * read.c (construct_include_path): Ditto.
3311 * remake.c (name_mtime): Ditto.
3312 * vpath.c (selective_vpath_search): Ditto.
3313 * dir.c (find_directory): Ditto.
3314 (local_stat): Ditto.
3315 (find_directory): Use ENULLLOOP() to wrap opendir().
3316 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3318 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3319 atomic_readdir() handling.
3321 2003-01-22 Paul D. Smith <psmith@gnu.org>
3323 * function.c (func_call): Fix Bug #1744. If we're inside a
3324 recursive invocation of $(call ...), mask any of the outer
3325 invocation's arguments that aren't used by this one, so that this
3326 invocation doesn't "inherit" them accidentally.
3328 2002-12-05 Paul D. Smith <psmith@gnu.org>
3330 * function.c (subst_expand): Valery Khamenia reported a
3331 pathological performance hit when doing substitutions on very
3332 large values with lots of words: turns out we were invoking
3333 strlen() a ridiculous number of times. Instead of having each
3334 call to sindex() call strlen() again, keep track of how much of
3335 the text we've seen and pass the length to sindex().
3337 2002-11-19 Paul D. Smith <psmith@gnu.org>
3339 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3342 2002-11-16 Paul D. Smith <psmith@gnu.org>
3344 * NMakefile.template (OBJS): Add hash.c object file.
3345 * SMakefile.template (srcs): Ditto.
3346 * Makefile.ami (objs): Ditto.
3347 * build_w32.bat: Ditto.
3349 * Makefile.DOS.template: Remove extra dependencies.
3351 2002-10-25 Paul D. Smith <psmith@gnu.org>
3353 * expand.c (install_variable_buffer): New function. Install a new
3354 variable_buffer context and return the previous one.
3355 (restore_variable_buffer): New function. Free the current
3356 variable_buffer context and put a previously saved one back.
3357 * variable.h: Prototypes for {install,restore}_variable_buffer.
3358 * function.c (func_eval): Push a new variable_buffer context
3359 before we eval, then restore the old one when we're done.
3360 Fixes Bug #1517.
3362 * read.c (install_conditionals): New function. Install a new
3363 conditional context and return the previous one.
3364 (restore_conditionals): New function. Free the current
3365 conditional context and put a previously saved one back.
3366 (eval): Use the {install,restore}_conditionals for "include"
3367 handling.
3368 (eval_buffer): Use {install,restore}_conditionals to preserve the
3369 present conditional state before we evaluate the buffer.
3370 Fixes Bug #1516.
3372 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3373 and $(value ...).
3374 (Recursion): Add a variable index entry for CURDIR.
3376 * README.cvs: Update to appropriate versions.
3377 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3378 don't need to copy loadavg.c: automake is smart enough to create
3379 it for me. Still have a bug in automake related to ansi2knr tho.
3381 2002-10-14 Paul D. Smith <psmith@gnu.org>
3383 * remake.c (notice_finished_file): Only touch targets if they have
3384 at least one command (as per POSIX). Resolve Bug #1418.
3386 * *.c: Convert to using ANSI C-style function definitions.
3387 * Makefile.am: Enable the ansi2knr feature of automake.
3388 * configure.in: ditto.
3390 2002-10-13 Paul D. Smith <psmith@gnu.org>
3392 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3393 for automatic variable values like $^, etc. In the case of very
3394 large lists of prerequisites this causes problems. Instead reuse
3395 a static buffer (resizeable) for each variable.
3397 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3398 target-specific variable definitions. Check for it and set an
3399 "exported" flag.
3400 (record_target_var): Set the export field to v_export if the
3401 "exported" flag is set.
3402 * doc/make.texi (Target-specific): Document the ability to use
3403 "export".
3405 * doc/make.texi: Change the name of the section on automatic
3406 variables from "Automatic" to "Automatic Variables". Added text
3407 clarifying the scope of automatic variables.
3409 2002-10-04 Paul D. Smith <psmith@gnu.org>
3411 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3412 as () braces.
3413 (record_files): Ditto.
3415 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3416 the search for the '=' to only within the enclosing parens.
3418 2002-10-03 Paul D. Smith <psmith@gnu.org>
3420 Version 3.80 released.
3422 * dir.c: Change hash functions to use K&R function definition style.
3423 * function.c: Ditto.
3424 * read.c: Ditto.
3425 * variable.c: Ditto.
3427 Update to automake 1.7.
3429 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3430 (pdf): Remove this target as automake now provides one.
3432 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3434 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3436 * makefile.com: Updates for GNU make 3.80.
3437 * makefile.vms: Ditto.
3439 2002-09-23 Paul D. Smith <psmith@gnu.org>
3441 * read.c (enum make_word_type): Remove w_comment.
3442 (get_next_mword): Don't treat comment characters as special; where
3443 this function is used we will never see a comment (it's stripped
3444 before we get here) and treating comments specially means that
3445 targets like "foo\#bar" aren't handled properly.
3447 2002-09-18 Paul D. Smith <psmith@gnu.org>
3449 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3451 * read.c (eval): Expansion of arguments to export/unexport was
3452 ignoring all arguments after the first one. Change the algorithm
3453 to expand the whole line once, then parse the results.
3455 2002-09-17 Paul D. Smith <psmith@gnu.org>
3457 Fix Bug #940 (plus another bug I found while looking at this):
3459 * read.c (record_target_var): enter_file() will add a new entry if
3460 it's a double-colon target: we don't want to do that in this
3461 situation. Invoke lookup_file() and only enter_file() if it does
3462 not already exist. If the file we get back is a double-colon then
3463 add this variable to the "root" double-colon target.
3465 * variable.c (initialize_file_variables): If this file is a
3466 double-colon target but is not the "root" target, then initialize
3467 the root and make the root's variable list the parent of our
3468 variable list.
3470 2002-09-13 Paul D. Smith <psmith@gnu.org>
3472 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3474 * hash.c (round_up_2): Get rid of a warning.
3476 2002-09-12 Paul D. Smith <psmith@gnu.org>
3478 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3479 so it doesn't complain about getloadavg.c.
3481 * commands.c (set_file_variables): Make sure we always alloca() at
3482 least 1 character for the value of $? (for '\0').
3484 2002-09-11 Paul D. Smith <psmith@gnu.org>
3486 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3487 macro to use RESULT instead of the incorrect _RESULT_.
3489 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3490 and atomic_readdir(). We need to #include dirent.h to get this to
3491 work.
3492 * misc.c (atomic_readdir): Fix typos.
3494 2002-09-10 Paul D. Smith <psmith@gnu.org>
3496 * read.c (eval): Expand variable lists given to export and
3497 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3498 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3500 * doc/make.texi (Variables/Recursion): Document this.
3501 (Conditional Syntax): And here.
3503 2002-09-09 Paul D. Smith <psmith@gnu.org>
3505 * configure.in: Check for memmove().
3507 2002-09-07 Paul D. Smith <psmith@gnu.org>
3509 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3510 Michael Sterrett <msterret@coat.com> reports that while it has
3511 SA_RESTART, it does not work properly.
3513 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3514 that invokes stat() and loops to do it again if it returns EINTR.
3515 (atomic_readdir): Ditto, with readdir().
3517 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3518 and readdir() to atomic_stat() and atomic_readdir().
3520 2002-09-04 Paul D. Smith <psmith@gnu.org>
3522 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3523 reports that GNU make sometimes doesn't recognize that targets can
3524 be made, when directories can be created as prerequisites. He
3525 reports that changing the order of predicates in the DEP->changed
3526 flag test so that lookup_file() is always performed, solves this
3527 problem.
3529 2002-08-08 Paul D. Smith <psmith@gnu.org>
3531 * configure.in: Require a newer version of gettext.
3533 * misc.c (perror_with_name): Translate the format string (for
3534 right-to-left language support).
3535 (pfatal_with_name): Ditto.
3537 * main.c: Create a static array of strings to store the usage
3538 text. This is done to facilitate translations.
3539 (struct command_switch): Remove argdesc and description fields.
3540 (switches): Remove values for obsolete fields.
3541 (print_usage): Print each element of the usage array.
3543 * hash.c: Change function definitions to be K&R style.
3545 2002-08-02 Paul D. Smith <psmith@gnu.org>
3547 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3548 this one because it's too hard to get right. We'll look at it for
3549 a future release.
3550 * main.c (main): Don't create the .TARGETS variable.
3551 * variable.c (handle_special_var): Don't handle .TARGETS.
3553 2002-08-01 Paul D. Smith <psmith@gnu.org>
3555 * main.c (switches): Add a new option, -B (--always-make). If
3556 specified, make will rebuild all targets that it encounters even
3557 if they don't appear to be out of date.
3558 (always_make_flag): New flag.
3559 * make.h: Extern always_make_flag.
3560 * remake.c (update_file_1): Check always_make_flag; if it's set we
3561 will always rebuild any target we can, even if none of its
3562 prerequisites are newer.
3563 * NEWS: Mention it.
3565 * doc/make.texi (Shell Function): Make it clear that make
3566 variables marked as "export" are not passed to instances of the
3567 shell function.
3569 Add new introspection variable .VARIABLES and .TARGETS.
3571 * variable.c (handle_special_var): New function. If the variable
3572 reference passed in is "special" (.VARIABLES or .TARGETS),
3573 calculate the new value if necessary. .VARIABLES is handled here:
3574 walk through the hash of defined variables and construct a value
3575 which is a list of the names. .TARGETS is handled by
3576 build_target_list().
3577 (lookup_variable): Invoke handle_special_var().
3578 * file.c (build_target_list): Walk through the hask of known files
3579 and construct a list of the names of all the ones marked as
3580 targets.
3581 * main.c (main): Initialize them to empty (and as simple variables).
3582 * doc/make.texi (Special Variables): Document them.
3583 * NEWS: Mention them.
3585 * variable.h (struct variable): Add a new flag "exportable" which
3586 is true if the variable name is valid for export.
3587 * variable.c (define_variable_in_set): Set "exportable" when a new
3588 variable is defined.
3589 (target_environment): Use the "exportable" flag instead of
3590 re-checking the name here... an efficiency improvement.
3592 2002-07-31 Paul D. Smith <psmith@gnu.org>
3594 * config.h-vms.template: Updates to build on VMS. Thanks to
3595 Brian_Benning@aksteel.com for helping verify the build.
3596 * makefile.com: Build the new hash.c file.
3597 * hash.h: Use strcpmi(), not stricmp(), in the
3598 HAVE_CASE_INSENSITIVE_FS case.
3600 2002-07-30 Paul D. Smith <psmith@gnu.org>
3602 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3603 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3604 Reported by <Brian_Benning@aksteel.com>.
3606 2002-07-10 Paul D. Smith <psmith@gnu.org>
3608 * variable.c (pop_variable_scope): Remove variable made unused by
3609 new hash infrastructure.
3610 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3611 comparisons as well as name comparisons.
3612 * variable.h: Add a prototype for new hash_init_function_table().
3613 * file.c (lookup_file): Remove variables made unused by new hash
3614 infrastructure.
3615 * dir.c (directory_contents_hash_2): Missing return of hash value.
3616 (dir_contents_file_exists_p): Remove variables made unused by new
3617 hash infrastructure.
3620 Installed Greg McGary's integration of the hash functions from the
3621 GNU id-utils package:
3623 2002-07-10 Greg McGary <greg@mcgary.org>
3625 * scripts/functions/filter-out: Add literals to to the
3626 pattern space in order to add complexity, and trigger
3627 use of an internal hash table. Fix documentation strings.
3628 * scripts/targets/INTERMEDIATE: Reverse order of files
3629 passed to expected `rm' command.
3631 2002-07-10 Greg McGary <greg@mcgary.org>
3633 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3634 * hash.c: New file, taken from id-utils.
3635 * hash.h: New file, taken from id-utils.

3644 (file_hash_enter): Remove function decl.
3645 (init_hash_files): New function decl.
3647 * ar.c (ar_name): Delay call to strlen until needed.
3648 * main.c (initialize_global_hash_tables): New function.
3649 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3650 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3651 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
3653 * dir.c (hash.h): New #include.
3654 (struct directory_contents) [next, files]: Remove members.
3655 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

3665 (find_directory): Use new hash table package.
3666 (dir_contents_file_exists_p): Likewise.
3667 (file_impossible): Likewise.
3668 (file_impossible_p): Likewise.
3669 (print_dir_data_base): Likewise.
3670 (open_dirstream): Likewise.
3671 (read_dirstream): Likewise.
3672 (hash_init_directories): New function.
3674 * file.c (hash.h): New #include.
3675 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
3676 (files): Change type to `struct hash_table'.
3677 (lookup_file): Use new hash table package.

3679 (remove_intermediates): Likewise.
3680 (snap_deps): Likewise.
3681 (print_file_data_base): Likewise.
3683 * function.c
3684 (function_table_entry_hash_1, function_table_entry_hash_2,
3685 function_table_entry_hash_cmp): New functions.
3686 (lookup_function): Remove `table' argument.
3687 Use new hash table package.
3688 (struct a_word) [chain, length]: New members.
3689 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3690 (struct a_pattern): New struct.
3691 (func_filter_filterout): Pass through patterns noting boundaries
3692 and '%', if present. Note a_word length. Use a hash table if
3693 arglists are large enough to justify cost.
3694 (function_table_init): Renamed from function_table.
3695 (function_table): Declare as `struct hash_table'.
3696 (FUNCTION_TABLE_ENTRIES): New constant.

3701 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3702 (uniquize_deps): Use hash table to efficiently identify duplicates.
3703 (find_char_unquote): Accept two char-constant stop chars, rather
3704 than a string constant, avoiding zillions of calls to strchr.
3705 Tighten inner search loops to test only for desired delimiters.
3707 * variable.c (variable_hash_1, variable_hash_2,
3708 variable_hash_cmp): New functions.

3720 (target_environment): Likewise.
3721 (print_variable_set): Likewise.
3723 2002-07-10 Paul D. Smith <psmith@gnu.org>
3725 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3726 prerequisite list. A real SysV make will expand the entire
3727 prerequisites list _twice_: we don't do that as it's a big
3728 backward-compatibility problem. We only replace those specific
3729 variables.
3731 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3732 references left in the list of prerequisites. Check for .POSIX as
3733 we record targets, so we can disable non-POSIX behavior while
3734 reading makefiles as well as running them.
3735 (eval): Check the prerequisite list to see if we have anything
3736 that looks like a SysV prerequisite variable reference.
3738 2002-07-09 Paul D. Smith <psmith@gnu.org>
3740 * doc/make.texi (Prerequisite Types): Add a new section describing
3741 order-only prerequisites.
3743 * read.c (uniquize_deps): If we have the same file as both a
3744 normal and order-only prereq, get rid of the order-only prereq,
3745 since the normal one supersedes it.
3747 2002-07-08 Paul D. Smith <psmith@gnu.org>
3749 * AUTHORS: Added Greg McGary to the AUTHORS file.
3750 * NEWS: Blurbed order-only prerequisites.
3751 * file.c (print_file): Show order-only deps properly when printing
3752 the database.
3754 * maintMakefile: Add "update" targets for wget'ing the latest
3755 versions of various external files. Taken from Makefile.maint in
3756 autoconf, etc.
3758 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3759 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3761 2002-07-07 Paul D. Smith <psmith@gnu.org>
3763 * po/*.po: Remove. We'll use wget to retrieve them at release
3764 time.
3766 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3767 rather than a shell you get an exception. Make sure we look up
3768 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3770 * remake.c (notice_finished_file): Fix handling of -t flag.
3771 Patch provided by Henning Makholm <henning@makholm.net>.
3773 * implicit.c (pattern_search): Some systems apparently run short
3774 of stack space, and using alloca() in this function caused an
3775 overrun. I modified it to use xmalloc() on the two variables
3776 which seemed like they might get large. Fixes Bug #476.
3778 * main.c (print_version): Update copyright notice to conform with
3779 GNU standards.
3780 (print_usage): Update help output.
3782 * function.c (func_eval): Create a new make function, $(eval
3783 ...). Expand the arguments, put them into a buffer, then invoke
3784 eval_buffer() on the resulting string.
3785 (func_quote): Create a new function, $(quote VARNAME). Inserts
3786 the value of the variable VARNAME without expanding it any
3787 further.
3789 * read.c (struct ebuffer): Change the linebuffer structure to an
3790 "eval buffer", which can be either a file or a buffer.
3791 (eval_makefile): Move the code in the old read_makefile() which
3792 located a makefile into here: create a struct ebuffer with that
3793 information. Have it invoke the new function eval() with that
3794 ebuffer.
3795 (eval_buffer): Create a new function that creates a struct ebuffer
3796 that holds a string buffer instead of a file. Have it invoke
3797 eval() with that ebuffer.
3798 (eval): New function that contains the guts of the old
3799 read_makefile() function: this function parses makefiles. Obtains
3800 data to parse from the provided ebuffer. Some modifications to
3801 make the flow of the function cleaner and clearer. Still could
3802 use some work here...
3803 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3804 contents of the define/endef variable from the ebuffer.
3805 (readstring): Read the next line from a string-style ebuffer.
3806 (readline): Read the next line from an ebuffer. If it's a string
3807 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3808 from the file.
3810 * dep.h (eval_buffer): Prototype eval_buffer();
3812 * variable.c (do_variable_definition): Make sure that all
3813 non-target-specific variables are registered in the global set.
3814 If we're invoked from an $(eval ...) we might be inside a $(call
3815 ...) or other function which has pushed a variable scope; we still
3816 want to define our variables from evaluated makefile code in the
3817 global scope.
3819 2002-07-03 Greg McGary <greg@mcgary.org>
3821 * dep.h (struct dep) [ignore_mtime]: New member.
3822 [changed]: convert to a bitfield.
3823 * implicit.c (pattern_search): Zero ignore_mtime.
3824 * main.c (main, handle_non_switch_argument): Likewise.
3825 * rule.c (convert_suffix_rule): Likewise.
3826 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3827 (read_makefile): Parse '|' in prerequisite list.
3828 (uniquize_deps): Consider ignore_mtime when comparing deps.
3829 * remake.c (update_file_1, check_dep): Don't force remake for
3830 dependencies that have d->ignore_mtime.
3831 * commands.c (FILE_LIST_SEPARATOR): New constant.
3832 (set_file_variables): Don't include a
3833 prerequisite in $+, $^ or $? if d->ignore_mtime.
3834 Define $|.
3836 2002-06-18 Paul D. Smith <psmith@gnu.org>
3838 * make.texinfo: Updates for next revision. New date/rev/etc.
3839 Recreate all Info menus. Change license on the manual to the GNU
3840 Free Documentation License. A number of typos.
3841 (Variables Simplify): Don't use "-" before it's defined.
3842 (Automatic Prerequisites): Rewrite the target example to work
3843 properly if the compile fails. Remove incorrect comments about
3844 how "set -e" behaves.
3845 (Text Functions): Move the "word", "wordlist", "words", and
3846 "firstword" functions here, from "File Name Functions".
3847 * make-stds.texi: Update from latest GNU version.
3848 * fdl.texi: (created) Import the latest GNU version.
3850 2002-06-06 Paul D. Smith <psmith@gnu.org>
3852 * variable.c (do_variable_definition): New function: extract the
3853 part of try_variable_definition() that actually sets the value
3854 into a separate function.
3855 (try_variable_definition): Call do_variable_definition() after
3856 parsing the variable definition string.
3857 (define_variable_in_set): Make the name argument const.
3859 * variable.h (enum variable_flavor): Make public.
3860 (do_variable_definition): Create prototype.
3862 * read.c (read_all_makefiles): Create a new built-in variable,
3863 MAKEFILE_LIST.
3864 (read_makefile): Add each makefile read in to this variable value.
3866 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3868 * Makefile.DOS.template: Tweak according to changes in the
3869 distribution. Add back the dependencies of *.o files.
3871 * configh.dos.template: Synchronize with config.h.in.
3873 2002-05-09 Paul D. Smith <psmith@gnu.org>
3875 * file.c (file_timestamp_now): Use K&R function declaration.
3877 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3878 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3879 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3880 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3881 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3882 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3883 nlist.n_name is a pointer rather than an array.
3885 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3886 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3887 * configure.in: Use it instead of the old version.
3889 * main.c (main): Prefer setvbuf() to setlinebuf().
3891 2002-05-08 Paul D. Smith <psmith@gnu.org>
3893 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3894 (loadavg_LDADD): Ditto.
3896 2002-04-29 Paul D. Smith <psmith@gnu.org>
3898 * expand.c (recursively_expand_for_file): Rename
3899 recursively_expand() to recursively_expand_for_file() and provide
3900 an extra argument, struct file. If the argument is provided, set
3901 the variable scope to that of the file before expanding.
3902 * variable.h (recursively_expand): Make this a macro that invokes
3903 recursively_expand_for_file() with a NULL file pointer.
3904 * variable.c (target_environment): Call the renamed function and
3905 provide the current file context.
3906 Fixes Debian bug #144306.
3908 2002-04-28 Paul D. Smith <psmith@gnu.org>
3910 Allow $(call ...) user-defined variables to be self-referencing
3911 without throwing an error. Allows implementation of transitive
3912 closures, among other possibly useful things.
3913 Requested by: Philip Guenther <guenther@sendmail.com>
3915 * variable.h (struct variable): Add a new field: exp_count, and
3916 new macros to hold its size and maximum value.
3917 (warn_undefined): Make this a macro.
3918 * variable.c (define_variable_in_set): Initialize it.
3919 * expand.c (recursively_expand): If we detect recursive expansion
3920 of a variable, check the exp_count field. If it's greater than 0
3921 allow the recursion and decrement the count.
3922 (warn_undefined): Remove this (now a macro in variable.h).
3923 * function.c (func_call): Before we expand the user-defined
3924 function, modify its exp_count field to contain the maximum
3925 number of recursive calls we'll allow. After the call, reset it
3926 to 0.
3928 2002-04-21 Paul D. Smith <psmith@gnu.org>
3930 Modified to use latest autoconf (2.53), automake (1.6.1), and
3931 gettext (0.11.1). We're using gettext's new "external" support,
3932 to avoid including libintl source with GNU make.
3934 * README.cvs: New file. Explain how to build GNU make from CVS.
3936 * configure.in: Modify checking for the system glob library.
3937 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3938 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3939 etc. will manage it correctly). Set an automake conditional
3940 USE_LOCAL_GLOB to decide whether to compile the glob library.
3942 * getloadavg.c (main): Include make.h in the "TEST" program to
3943 avoid warnings.
3945 * Makefile.am: Remove special rules for loadavg. Replace them
3946 with Automake capabilities for building extra programs.
3948 * signame.c: This file does nothing if the system provide
3949 strsignal(). If not, it implements strsignal(). If the system
3950 doesn't define sys_siglist, then we make our own; otherwise we use
3951 the system version.
3952 * signame.h: Removed.
3954 * main.c (main): No need to invoke signame_init(). Update copyright.
3956 * ABOUT-NLS: Removed.
3957 * gettext.c: Removed.
3958 * gettext.h: Get a simplified copy from the gettext package.
3959 * po/*: Created.
3960 * i18n/*.po: Moved to po/.
3961 * i18n/: Removed.
3963 * config/*: Created. Contains package configuration helper files.
3964 * config.guess, config.sub: Moved to config directory.
3966 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3967 Rework to use new-style autoconf features. Use the "external"
3968 mode for gettext. Make the build.sh config file conditional on
3969 whether build.sh.in exists, to avoid autoconf errors.
3970 * acinclude.m4: Removed almost all macros as being obsolete.
3971 Rewrote remaining macros to use AC_DEFINE.
3972 * acconfig.h: Removed.
3974 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3975 conditional to handle customs support. Remove special handling
3976 for i18n features.
3978 2002-04-20 Paul D. Smith <psmith@gnu.org>
3980 * function.c (func_call): Don't mark the argument variables $1,
3981 etc. as recursive. They've already been fully expanded so
3982 there's no need to do it again, and doing so strips escaped $'s.
3983 Reported by Sebastian Glita <glseba@yahoo.com>.
3985 * remake.c (notice_finished_file): Walk through double-colon
3986 entries via the prev field, not the next field!
3987 Reported by Greg McGary <greg@mcgary.org>.
3989 * main.c (main): If the user specifies -q and asks for a specific
3990 target which is a makefile, we got an assert. In that case it
3991 turns out we should continue normally instead.
3993 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3995 * i18n/he.po: Installed a new translation.
3997 2002-01-07 Paul D. Smith <psmith@gnu.org>
3999 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4001 2001-12-04 Paul D. Smith <psmith@gnu.org>
4003 * i18n/ja.po: Installed an updated translation.
4005 2001-09-06 Paul Eggert <eggert@twinsun.com>
4007 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4008 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4010 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4011 are available.
4012 (main): Get rid of any avoidable limit on stack size.
4014 2001-09-04 Paul D. Smith <psmith@gnu.org>
4016 * i18n/da.po: Installed an updated translation.
4018 2001-08-03 Paul D. Smith <psmith@gnu.org>
4020 * i18n/fr.po: Installed an updated translation.
4021 Resolves Debian bug #106720.
4023 2001-06-13 Paul D. Smith <psmith@gnu.org>
4025 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4026 translation.
4028 2001-06-11 Paul D. Smith <psmith@gnu.org>
4030 * i18n/ko.po: Installed a new translation.
4032 2001-05-06 Paul D. Smith <psmith@gnu.org>
4034 Modify the EINTR handling.
4036 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4037 the way in which we manage the file descriptor/signal handler race
4038 trap to be more efficient.
4040 2001-05-06 Paul Eggert <eggert@twinsun.com>
4042 Restart almost all system calls that are interrupted, instead
4043 of worrying about EINTR. The lone exception is the read() for
4044 job tokens.
4046 * configure.in (HAVE_SA_RESTART): New macro.
4047 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4048 * main.c (main): Use SA_RESTART instead of the old,
4049 nonstandard SA_INTERRUPT.
4051 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4052 * main.c (bsd_signal): New function or macro,
4053 if the implementation doesn't supply it.
4054 (The bsd_signal function will be in POSIX 1003.1-200x.)
4055 (HANDLESIG): Remove.
4056 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4058 * make.h (EINTR_SET): Remove.
4059 (SA_RESTART): New macro.
4061 * arscan.c (ar_member_touch): Don't worry about EINTR.
4062 * function.c (func_shell): Likewise.
4063 * job.c (reap_children, free_child, new_job): Likewise.
4064 * main.c (main): Likewise.
4065 * remake.c (touch_file, name_mtime): Likewise.
4067 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4068 if fstat failed with errno!=EINTR, the error was ignored.
4070 * job.c (set_child_handler_action_flags): New function.
4071 (new_job): Use it to temporarily clear the SIGCHLD action flags
4072 while reading the token.
4074 2001-05-02 Paul D. Smith <psmith@gnu.org>
4076 * job.c (start_job_command): Don't add define/endef per-line flags
4077 to the top-level flags setting.
4079 2001-04-03 Paul D. Smith <psmith@gnu.org>
4081 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4082 bit on error, so check for odd return values, not non-0 return
4083 values.
4084 (VMS_get_member_info): Calculate the timezone differences correctly.
4085 Reported by John Fowler <jfowler@nyx.net>.
4088 2001-03-14 Paul D. Smith <psmith@gnu.org>
4090 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4091 value before invoking define_variable().
4092 Reported by John Fowler <jfowler@nyx.net>.
4094 2001-02-07 Paul D. Smith <psmith@gnu.org>
4096 * read.c (record_target_var): If we reset the variable due to a
4097 command-line variable setting overriding it, turn off the "append"
4098 flag.
4100 2001-01-17 Paul D. Smith <psmith@gnu.org>
4102 * variable.c (lookup_variable) [VMS]: When getting values from the
4103 environment, allocate enough space for the _value_ plus escapes,
4104 not enough space for the name plus escapes :-/.
4105 Reported by John Fowler <jfowler@nyx.net>.
4107 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4108 warnings that make generates, so it doesn't look like an error.
4109 Reported by Karl Berry <karl@gnu.org>.
4112 Fix for PR/2020: Rework appended target-specific variables. I'm
4113 fairly confident this algorithm is finally correct.
4115 * expand.c (allocated_variable_append): Rewrite. Instead of
4116 expanding each appended variable then adding all the expanded
4117 strings together, we append all the unexpanded values going up
4118 through the variable set contexts, then expand the final result.
4119 This behaves just like non-target-specific appended variable
4120 values, while the old way didn't in various corner cases.
4121 (variable_append): New function: recursively append the unexpanded
4122 value of a variable, walking from the outermost variable scope to
4123 the innermost.
4124 * variable.c (lookup_variable): Remove the code that looked up the
4125 variable set list if the found variable was "append". We don't
4126 need this anymore.
4127 (lookup_variable_in_set): Make this non-static so we can use it
4128 elsewhere.
4129 (try_variable_definition): Use lookup_variable_in_set() rather
4130 than faking out current_variable_set_list by hand (cleanup).
4131 * variable.h: Add a prototype for the now non-static
4132 lookup_variable_in_set().
4134 2000-11-17 Paul D. Smith <psmith@gnu.org>
4136 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4137 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4138 before throwing a fit.
4140 2000-11-17 Paul D. Smith <psmith@gnu.org>
4142 * read.c (readline): CRLF calculations had a hole, if you hit the
4143 buffer grow scenario just right. Reworked the algorithm to avoid
4144 the need for len or lastlen at all. Problem description with
4145 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4147 2000-10-24 Paul D. Smith <psmith@gnu.org>
4149 * gettext.c (SWAP): Declare this with the prototype, otherwise
4150 some systems don't work (non-32-bit? Reported for Cray T3E).
4151 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4153 2000-10-05 Paul D. Smith <psmith@gnu.org>
4155 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4156 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4158 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4160 2000-09-22 Paul D. Smith <psmith@gnu.org>
4162 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4163 parts of the real gettext.h here, and we expect to really include
4164 the real gettext.h later. If we keep this #define, it's ignored.
4166 2000-09-21 Paul D. Smith <psmith@gnu.org>
4168 * main.c (log_working_directory): Rework the text to use complete
4169 sentences, to make life simpler for the translators.
4171 2000-08-29 Paul D. Smith <psmith@gnu.org>
4173 * file.c (remove_intermediates): Print a debug message before we
4174 remove intermediate files, so the user (if she uses -d) knows
4175 what's going on.
4177 2000-08-21 Paul D. Smith <psmith@gnu.org>
4179 * variable.c (try_variable_definition): Change how we handle
4180 target-specific append variable defns: instead of just setting the
4181 value, expand it as an append _but_ only within the current
4182 target's context. Otherwise we lose all but the last value if the
4183 variable is appended more than once within the current target
4184 context. Fixes PR/1831.
4186 2000-08-16 Paul D. Smith <psmith@gnu.org>
4188 * function.c (func_shell): Nul-terminate the buffer before
4189 printing an exec error message (just in case it's not!).
4190 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4192 2000-07-25 Paul D. Smith <psmith@gnu.org>
4194 * job.c (construct_command_argv_internal): Add "~" to the list of
4195 sh_chars[] which disallow optimizing out the shell call.
4197 2000-07-23 Paul Eggert <eggert@twinsun.com>
4199 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4200 supersedes --disable-nsec-timestamps.
4201 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4202 * README: Remove --disable-nsec-timestamps.
4204 * filedef.h (struct file.low_resolution_time): New member.
4205 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4206 * remake.c (update_file_1):
4207 Avoid spurious rebuilds due to low resolution time stamps,
4208 generalizing the earlier code that applied only to archive members.
4209 (f_mtime): Archive members always have low resolution time stamps.
4211 * configure.in: Remove --disable-nsec-timestamps, as this has
4212 been superseded by .LOW_RESOLUTION_TIME.
4214 2000-07-23 Paul Eggert <eggert@twinsun.com>
4216 * configure.in (enable_nsec_timestamps): Renamed from
4217 make_cv_nsec_timestamps, since enable/disable options
4218 shouldn't be cached.
4220 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4221 and Paul Eggert <eggert@twinsun.com>
4223 * file.c (file_timestamp_now):
4224 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4225 so that clock_gettime is not linked unless needed.
4227 * filedef.h (FILE_TIMESTAMP_HI_RES):
4228 Remove definition; "configure" now does this.
4230 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4231 to before high resolution file timestamp check,
4232 since that check now uses uintmax_t.
4233 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4234 high resolution file timestamps.
4235 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4236 so that we don't link in clock_gettime unnecessarily.
4238 2000-07-17 Paul D. Smith <psmith@gnu.org>
4240 * i18n/ja.po: New version of the translation file.
4242 2000-07-07 Paul D. Smith <psmith@gnu.org>
4244 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4245 the offset calculation.
4246 (name_mtime): Replace EINTR test with EINTR_SET macro.
4248 2000-07-07 Paul Eggert <eggert@twinsun.com>
4250 Fix for PR/1811:
4252 * remake.c (update_file_1):
4253 Avoid spurious rebuilds of archive members due to their
4254 timestamp resolution being only one second.
4255 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4256 the clock's resolution being lower than file timestamps'.
4257 When warning about future timestamps, report only the discrepancy,
4258 not the absolute value of the timestamp and the current time.
4260 * file.c (file_timestamp_now): New arg RESOLUTION.
4261 * filedef.h (file_timestamp_now): Likewise.
4262 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4264 2000-07-05 Paul D. Smith <psmith@gnu.org>
4266 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4267 to listp. Fixes PR/1793.
4269 2000-06-26 Paul Eggert <eggert@twinsun.com>
4271 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4273 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4275 * remake.c (f_mtime): Remove unused var memtime.
4277 2000-06-25 Martin Buchholz <martin@xemacs.org>
4279 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4280 Ran spell-check on make.texinfo.
4282 2000-06-23 Paul D. Smith <psmith@gnu.org>
4284 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4285 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4286 * make.h: Define these macros.
4288 * Version 3.79.1 released.
4290 * configure.in: Add a new option, --disable-nsec-timestamps, to
4291 avoid using sub-second timestamps on systems that support it. It
4292 can lead to problems, e.g. if your makefile relies on "cp -p".
4293 * README.template: Document the issue with "cp -p".
4295 * config.guess, config.sub: Updated.
