3 * main.c (main): If we're re-exec'ing and we're the master make,
4 then restore the job_slots value so it goes back into MAKEFLAGS
5 properly. See Savannah bug #33873.

8 static vars like buflen etc. are computed, so it must be static
9 as well. See Savannah bug #32511.
11 2011-09-16 Paul Smith <psmith@gnu.org>

34 2011-08-29 Paul Smith <psmith@gnu.org>
36 * expand.c (variable_expand_string): Always allocate a new buffer
37 for a string we're expanding. The string we're working on can get
38 freed while we work on it (for example if it's the value of a

40 See Savannah patch #7534 for the original report by Lubomir Rintel.
42 2011-06-12 Paul Smith <psmith@gnu.org>

102 (parse_variable_definition): Parse "!=" shell assignments.
103 * read.c (get_next_mword): Treat "!=" as a varassign word.
104 * function.c (fold_newlines): If trim_newlines is set remove all
105 trailing newlines; otherwise remove only the last newline.

109 2011-02-21 Paul Smith <psmith@gnu.org>
111 * strcache.c (various): Increase performance based on comments
112 from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>. Stop looking for
113 a buffer when we find the first one that fits, not the best fit.
114 If there is not enough free space in a buffer move it to a
115 separate list so we don't have to walk it again.

548 2009-10-03 Paul Smith <psmith@gnu.org>
550 * make.h: Include <alloca.h> even on systems where __GNUC__ is
551 defined. Not sure why it was done the other way.
552 Requested by David Boyce <dsb@boyski.com>.
554 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
556 * dep.h (dep): Add the DONTCARE bitfield.
558 * filedef.h (file):Add the NO_DIAG bitfield.
560 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
561 not struct file (a file can be a dependency of many targets,
562 some don't care, some do).
564 * remake.c (update_goal_chain): Propagate DONTCARE from struct
565 dep to struct file before updating the goal and restore it
567 (update_file): Don't prune the dependency graph if this target
568 has failed but the diagnostics hasn't been issued.
569 (complain): Scan the file's dependency graph to find the file
570 that caused the failure.
571 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
572 whether to print diagnostics.
574 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
576 2009-09-28 Paul Smith <psmith@gnu.org>
578 * doc/make.texi (Pattern Intro): Move the match algorithm
579 discussion into the "Pattern Match" node.
580 (Pattern Match): Expand on the pattern rule matching algorithm.
582 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
584 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
585 much of the command line on a single pass.
587 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
589 * varible.c (create_pattern_var): Insert variables into the
590 PATTERN_VARS list in the shortest patterns first order.
592 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
593 used to sort the rules.
594 (stemlen_compare): Compare two tryrule elements.
595 (pattern_search): Sort the rules so that they are in the shortest
598 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
600 * doc/make.texi (Pattern-specific Variable Values): Describe the
601 new pattern-specific variables application order.
602 (Introduction to Pattern Rules): Describe the new pattern rules
605 * NEWS: Add a note about the new behavior.
607 2009-09-27 Paul Smith <psmith@gnu.org>
609 * doc/make.texi (Double-Colon): Mention that pattern rules with
610 double-colons have a different meaning. Savannah bug #27497.
612 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
614 * configh.dos.template: Remove unconditional definition of
615 SYS_SIGLIST_DECLARED.
616 Include <sys/version.h> because ports of GCC 4.3.0 and later no
617 longer include it, so macros like __DJGPP_MINOR__ are no longer
618 defined automatically.
620 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
621 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
622 instead of using the hardcoded ones.
623 (SUBDIRS): doc subdir added.
624 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
625 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
626 create html formated docs. texi2html may not be ported to DOS.
627 (make.info, make.dvi, make.ps, make.html): Make targets depend on
629 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
630 -I switch to look in ./ instead of ./doc.
631 (html): Target depend on html-recursive instead of make_1.html.
632 (make_1.html): Removed.
633 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
634 (all-recursive): Allow for more than one subdir in the build
636 (mostlyclean-recursive, clean-recursive, distclean-recursive)
637 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
638 (tags-recursive): Allow for more than one subdir in the build
640 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
641 targets. Enter into doc/ to produce the targets.
642 (all-am): $(INFO_DEPS) replaced by info.
644 2009-09-26 Paul Smith <psmith@gnu.org>
646 * read.c (record_files): Use free_ns() to free struct nameseq.
649 * rule.c (freerule): Use free_dep_chain().
651 * read.c (record_files): Free FILENAMES chain for implicit rules.
652 (eval): Static pattern targets go into the string cache.
654 * function.c (string_glob): Free NAME in the nameseq chain.
656 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
658 * implicit.c (pattern_search): Terminate early if we haven't
659 found any rules to try (performance improvement).
661 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
663 * implicit.c (pattern_search): Merge three parallel arrays,
664 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
665 of struct TRYRULE. In the old version the latter two arrays
666 had insufficient length.
668 2009-09-24 Paul Smith <psmith@gnu.org>
670 * implicit.c (pattern_search): Add back support for order-only
671 prerequisites for secondary expansion implicit rules, that were
672 accidentally dropped. If we find a "|", enable order-only mode
673 and set IGNORE_MTIME on all deps that are seen afterward.
674 (pattern_search): Fix memory leaks: for intermediate files where
675 we've already set the file variable and pattern variable sets, be
676 sure to either save or free them as appropriate.
678 2009-09-23 Paul Smith <psmith@gnu.org>
680 Rework the way secondary expansion is stored, for efficiency.
681 This changes secondary expansion so that ONLY WHEN we know we have
682 a possibility of needing secondary expansion, do we defer the
683 secondary expansion. This means more parsing the deps but we use
684 a lot less memory (due to the strcache). Also, this fixes
687 * read.c (eval): Don't parse the dep string here anymore.
688 (record_files): Take the dep argument as an unparsed string. If
689 secondary expansion is enabled AND the prereq string has a '$' in
690 it, then set NEED_2ND_EXPANSION and keep the entire string.
691 Otherwise, parse the dep string here to construct the dep list
692 with the names in the strcache.
694 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
695 duplicate the name string (others are in the strcache).
697 * implicit.c: Remove struct idep and free_idep_chain(): unused.
698 (struct patdeps): New structure to store prereq information.
699 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
700 which prerequisites need expansion, and expand only those.
702 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
703 and enter_prereqs(). split_prereqs() takes a fully-expanded string
704 and splits it into a DEP list, handling order-only prereqs.
705 (enter_prereqs): This function enters a list of DEPs into the file
706 database. If there's a stem defined, expand any pattern chars.
707 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
708 set. Use the above functions.
709 (snap_deps): Only perform second expansion on prereqs that need it,
710 as defined by the NEED_2ND_EXPANSION flag.
711 (print_prereqs): New function to print the prereqs
712 (print_file): Call print_prereqs() rather than print inline.
714 * hash.h (STRING_COMPARE): Take advantage of strcache() by
716 (STRING_N_COMPARE): Ditto.
717 (ISTRING_COMPARE): Ditto.
719 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
720 (parse_file_seq): Return void*
721 * read.c (parse_file_seq): Return void*.
722 (eval): Invoke macroized version of parse_file_seq()
723 * default.c (set_default_suffixes): Ditto.
724 * file.c (split_prereqs): Ditto.
725 * function.c (string_glob): Ditto.
726 * main.c (main): Ditto.
727 * rule.c (install_pattern_rule): Ditto.
729 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
731 2009-09-16 Paul Smith <psmith@gnu.org>
733 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
735 * dep.h: Create alloc_dep() / free_dep() macros.
737 * implicit.c (pattern_search): Take advantage of the new
738 parse_file_seq() to add the directory prefix to each prereq.
740 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
741 all. Avoid reversing chains. Support adding prefixes.
742 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
743 cached/non-cached results.
744 (eval): Remove multi_glob() & invoke new parse_file_seq().
745 * rule.c (install_pattern_rule): Ditto.
746 * main.c (main): Ditto.
747 * implicit.c (pattern_search): Ditto.
748 * function.c (string_glob): Ditto.
749 * file.c (parse_prereqs): Ditto.
750 * default.c (set_default_suffixes): Ditto.
752 * variable.c (parse_variable_definition): Don't run off the end of
753 the string if it ends in whitespace (found with valgrind).
755 * commands.c (set_file_variables): Keep space for all targets in
756 $? if -B is given (found with valgrind).
758 2009-09-15 Paul Smith <psmith@gnu.org>
760 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
761 (xcalloc): Add new function.
762 * make.h: New declarations.
764 * ar.c (ar_glob_match): New calling method for concat().
765 * main.c (main): Ditto.
766 (decode_env_switches): Ditto.
767 * read.c (eval_makefile): Ditto.
768 (tilde_expand): Ditto.
769 (parse_file_seq): Ditto.
770 * variable.c (target_environment): Ditto.
771 (sync_Path_environment): Ditto.
773 * ar.c (ar_glob_match): Use xcalloc().
774 * dir.c (file_impossible): Ditto.
775 * file.c (enter_file): Ditto.
776 * job.c (new_job): Ditto.
777 * read.c (parse_file_seq): Ditto.
778 * vmsfunctions.c (opendir): Ditto.
780 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
782 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
783 inside the loop that looks up environment for PATH.
785 2009-08-31 Eli Zaretskii <eliz@gnu.org>
787 * function.c (windows32_openpipe): Update envp after calling
788 sync_Path_environment.
790 2009-08-02 Paul Smith <psmith@gnu.org>
792 * remake.c (notice_finished_file): Ensure file->cmds is not null
793 before looping through them. Fixes Savannah bug #21824.
795 * doc/make.texi (Wildcard Examples): Clarify when objects is
796 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
797 (Include): Clarify the behavior of -include.
798 Fixes Savannah bug #18963.
800 2009-08-01 Paul Smith <psmith@gnu.org>
802 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
803 etc. come on the command line. Fixes Savannah bug #27093.
805 * expand.c (expand_argument): If the argument is large enough use
806 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
808 * variable.c (do_variable_definition): Avoid using alloca() to
809 hold values, which can be large. Fixes Savannah bug #23960.
811 * job.c (new_job): Use memmove() instead of strcpy() since both
812 pointers are in the same memory block. Fixes Savannah bug #27148.
813 Patch by Petr Machata.
815 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
817 * job.c (construct_command_argv_internal): Add "ulimit" and
818 "unset" to the sh_cmds for Unixy shells.
820 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
822 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
823 that set make_cv_sys_gnu_glob, so they are also correctly set
824 when the cache has been populated before.
826 2009-07-04 Eli Zaretskii <eliz@gnu.org>
828 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
829 exist, as realpath(3) does where it's supported.
831 2006-07-04 Eli Zaretskii <eliz@gnu.org>
833 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
834 (abspath): Support systems that define HAVE_DOS_PATHS (have
835 drive letters in their file names). Use IS_PATHSEP instead of a
836 literal '/' comparison. Fixes Savannah bug #26886.
838 2009-06-14 Paul Smith <psmith@gnu.org>
840 * remake.c (update_file_1): Remember the original file we marked
841 as updating, so we can clear that flag again. If we find a target
842 via vpath, FILE might change.
843 (check_dep): Ditto. Fixes Savannah bug #13529.
844 Patch by Reid Madsen <reid.madsen@tek.com>.
846 2009-06-13 Paul Smith <psmith@gnu.org>
848 * doc/make.texi (MAKEFILES Variable): Be explicit that files
849 included by MAKEFILES cannot give default goals.
850 * read.c (eval): If set_default is not set, pass the no-default-goal
851 value when we read included makefiles. Fixes Savannah bug #13401.
853 * ar.c (ar_name): Ensure that targets with empty parens aren't
854 considered archive member references: archive members must have a
855 non-empty "member" string. Fixes Savannah bug #18435.
857 * function.c (string_glob): Rely on multi_glob() to determine
858 whether files exist or not. Remove call to file_exists_p() which
859 is not always correct. Fixes Savannah bug #21231.
860 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
861 then only files that really exist will be returned.
862 * dep.h: Add new argument to multi_glob().
863 * rule.c (install_pattern_rule): Ditto.
864 * read.c (eval): Ditto.
865 * main.c (main): Ditto.
866 * implicit.c (pattern_search): Ditto.
867 * file.c (parse_prereqs): Ditto.
868 * default.c (set_default_suffixes): Ditto.
870 2009-06-09 Paul Smith <psmith@gnu.org>
872 * commands.c (set_file_variables): If always_make_flag is set,
873 always add the prereq to $?. Fixes Savannah bug #17825.
875 * remake.c (update_file_1): When rebuilding deps of FILE, also try
876 to rebuild the deps of all the also_make targets for that file.
877 Fixes Savannah bug #19108.
879 * implicit.c (pattern_search): Undo test for is_target, added by
880 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
881 Rule Search Algorithm". Fixes Savannah bug #17752.
883 * main.c (clean_jobserver): Clear the jobserver_fds options and
884 set job_slots to the default when we clean up.
885 (define_makeflags): Return the new MAKEFLAGS value.
886 (main): Reset MAKEFLAGS in the environment when we re-exec.
887 Fixes Savannah bug #18124.
889 2009-06-08 Paul Smith <psmith@gnu.org>
891 * read.c (eval): Collapse continuations post-semicolon on target-
892 specific variables. Fixes Savannah bug #17521.
894 2009-06-07 Paul Smith <psmith@gnu.org>
896 * job.c (reap_children): For older systems without waitpid() (are
897 there any of these left?) run wait(2) inside EINTRLOOP to handle
898 EINTR errors. Fixes Savannah bug #16401.
900 * (various): Debug message cleanup. Fixes Savannah bug #16469.
902 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
904 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
905 not the end, to catch second expansion $(eval ...) defining new
906 target/prereq relationships during snap_deps.
907 Fixes Savannah bug #24622.
909 * read.c (record_files): The second-expansion "f->updating" hack
910 was not completely correct: if assumed that the target with
911 commands always had prerequisites; if one didn't then the ordering
912 was messed up. Fixed for now to use f->updating to decide whether
913 to preserve the last element in the deps list... but this whole
914 area of constructing and reversing the deps list is too confusing
915 and needs to be reworked. Fixes Savannah bug #21198.
917 2009-06-06 Paul Smith <psmith@gnu.org>
919 * hash.c (hash_insert): Remove useless test for NULL.
920 Fixes Savannah bug #21823.
922 * make.h: Move SET_STACK_SIZE determination to make.h.
923 * main.c (main): New global variable, STACK_LIMIT, holds the
924 original stack limit when make was started.
925 * job.c (start_job_command): Reset the stack limit, if we changed it.
926 Fixes Savannah bug #22010.
928 * remake.c (check_dep): Only set the target's state to not-started
929 if it's not already running. Found this while testing -j10 builds
930 of glibc: various targets were being rebuilt multiple times.
931 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
934 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
935 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
938 2009-06-04 Paul Smith <psmith@gnu.org>
940 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
942 * maintMakefile: Modify access of config and gnulib Savannah
943 modules to use GIT instead of CVS.
945 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
946 Fixes Savannah bug #24655.
948 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
949 this can happen during some invocations of $(eval ...) for example.
950 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
952 2009-06-02 Paul Smith <psmith@gnu.org>
954 * configure.in: Check for fileno()
955 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
956 for the makefile file so invocations of $(shell ...) don't inherit it.
957 Fixes Savannah bug #24277.
959 2009-06-01 Paul Smith <psmith@gnu.org>
961 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
962 expansion was handled incorrectly. Rework the default goal
963 handling to save the variable only. Remove default_goal_file and
965 * read.c (eval): Check default_goal_var, not default_goal_name.
966 * read.c (record_target_var): Don't check default_goal_file here.
968 2009-05-31 Paul Smith <psmith@gnu.org>
970 * main.c (main): Expand the .DEFAULT_GOAL variable before using
971 it, and if the multi_glob() returns nothing (say it expanded to
972 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
974 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
975 $(and ..) to the reference. Fixes Savannah bug #25694.
977 * make.1: Be clear that some recipes will be executed even with -n.
978 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
980 * doc/make.texi (Override Directive): Make more clear how
981 overrides and appends interact.
982 Elucidates part of Savannah bug #26207.
984 * read.c (record_target_var): Don't reset the origin on
985 target-specific variables; try_variable_definition() will handle
986 this correctly. Fixes Savannah bug #26207.
988 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
989 Fixes Savannah bug #25712.
991 * implicit.c (pattern_search): Keep a pointer to the beginning of
992 the filename and save that instead of the constructed pointer.
993 Fixes Savannah bug #26593.
994 Patch by Mark Seaborn <mrs@mythic-beasts.com>
996 2009-05-30 Paul Smith <psmith@gnu.org>
998 * doc/make.texi (Multi-Line): Add a description of the new abilities
999 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1000 "command sequence" vs. "recipe" syntax.
1001 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1002 after a define, to create variables with those flavors.
1004 2009-05-25 Paul Smith <psmith@gnu.org>
1006 Reworked the parser for variable assignments to allow multiple
1007 modifiers, and in any order. Also allows variable and
1008 prerequisites to be modifier names ('export', 'private', etc.)
1010 * NEWS: Add notes about user-visible changes.
1012 * read.c (struct vmodifiers): Remember what modifiers were seen.
1013 (parse_var_assignment): New function to parse variable assignments.
1014 (eval): Call the new function. Handle variable assignments earlier.
1016 * variable.c (parse_variable_definition): Only parse; don't create var.
1017 (assign_variable_definition): Call parse, then create the var.
1019 2009-05-24 Paul Smith <psmith@gnu.org>
1021 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1022 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1024 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1026 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1027 Fixes Savannah bug #25412.
1029 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1030 prototype for xmalloc.
1031 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1032 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1033 Loop over an array of extensions, instead of duplicating the same
1034 code inline. Use SearchPath followed by CreateFile, instead of
1035 the obsolete OpenFile. Fixes Savannah bug #17277.
1036 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1037 to `find_file'. Fixes Savannah bug #25662.
1039 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1041 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1042 Fixes Savannah bug #20495.
1044 2009-02-28 Ralf Wildenhues <address@hidden>
1046 * doc/make.texi (Instead of Execution): Document interaction of
1047 -t with phony targets.
1049 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1051 Introduce a new keyword "private" which applies to target-specific
1052 variables and prevents their values from being inherited.
1054 * variable.h (struct variable): Add private_var flag to each variable.
1055 Add a flag to specify which list entry switches to the parent target.
1056 * variable.c (define_variable_in_set): Initialize private_var flag.
1057 (lookup_variable): Skip private variables in parent contexts.
1058 (initialize_file_variables): Set next_is_parent appropriately.
1059 (print_variable): Show the private_var flag.

1061 (record_target_var): Set private_var.
1062 * doc/make.texi (Suppressing Inheritance): Add documentation.
1064 2008-10-26 Paul Smith <psmith@gnu.org>
1066 * configure.in: Check for strndup().
1067 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
1069 * make.h: Rename savestring to xstrndup.
1070 * commands.c (chop_commands): Ditto.

1138 HAVE_DECL_SYS_SIGLIST.
1140 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1141 build does not use child_execute_job.
1143 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1144 export the SHELL environment variable to the child.

1168 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1170 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1171 a more complex value than a simple shell: if it's not a default
1172 shell now then expand it and see if is a default shell then.
1174 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1176 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1177 pathnames, with const strings.
1178 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1179 from the template (used for building from CVS, not a dist).
1181 2007-10-10 Paul Smith <psmith@gnu.org>
1183 * make.h: Add a prototype for w32_kill() (change suggested by

1198 2007-09-11 Paul Smith <psmith@gnu.org>
1200 * doc/make.texi (Special Variables): Moved this into the "How to
1201 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1206 (Rule Syntax): Ditto.
1207 (Command Syntax): Ditto.
1208 (Error Messages): Ditto.
1210 2007-09-10 Paul Smith <psmith@gnu.org>
1212 * commands.c (print_commands): Don't print an extra line in the
1213 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1215 * read.c (construct_include_path): Add the full string to the cache; we
1216 were chopping the last char.
1218 * NEWS: Announce the .RECIPEPREFIX special variable.
1219 * variable.c (lookup_special_var): Rename from handle_special_var().
1220 (lookup_variable): Call the new name.
1221 (set_special_var): New function: handle setting of special variables.
1222 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1223 (do_variable_definition): Call it.
1224 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1225 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1226 * main.c (main): Create the .RECIPEPREFIX special variable.
1227 * read.c (eval): Remove the cmd_prefix characters from the command
1228 scripts here, so they're not stored in the commands array at all,
1229 rather than waiting and stripping them out during command construction.
1230 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1232 2007-08-15 Paul Smith <psmith@gnu.org>
1234 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1235 file has had the section info removed, so add some to make.texi
1236 before we include it.
1238 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1240 * remake.c (check_dep): Reset the target state for intermediate
1241 files. They might have been considered before but not updated

1256 2007-07-13 Paul Smith <psmith@gnu.org>
1258 * file.c (expand_deps): Use variable_buffer as the start of the
1259 buffer, not the original pointer (in case it was reallocated).
1260 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1261 Fixes Savannah bug #20452.
1263 2007-07-04 Paul Smith <psmith@gnu.org>

1298 Dave Korn <dave.korn@artimi.com>
1300 2007-05-08 Paul Smith <psmith@gnu.org>
1302 Fix Savannah bug #19656:
1304 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1306 * make.h: Change all case-insensitive string compares to use
1307 strcasecmp() (from POSIX). If we don't have that but do have one
1308 of the others, define strcasecmp to be one of those instead. If
1309 we don't have any, declare a prototype for our own version.
1311 * misc.c (strcasecmp): Use this if we can't find any native
1312 case-insensitive string comparison function.
1313 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1314 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1316 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1317 strcasecmp() instead of stricmp().
1318 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1319 instead of strcmpi().
1320 * acinclude.m4: Remove the strcasecmp() check from here.
1322 2007-03-21 Paul Smith <psmith@gnu.org>
1324 * configure.in: Don't turn on case-insensitive file system support
1325 if --disable-... is given. Fixes Savannah bug #19348.
1327 2007-03-19 Paul Smith <psmith@gnu.org>
1329 * ALL: Use the strcache for all file name strings, or other
1330 strings which we will never free. The goal is to save memory by
1331 avoiding duplicate copies of strings. However, at the moment this
1332 doesn't save much memory in most situations: due to secondary
1333 expansion we actually save prerequisite lists twice (once before
1334 the secondary expansion, and then again after it's been parsed
1335 into individual file names in the dep list). We will resolve this
1336 in a future change, by doing the parsing up-front for targets
1337 where secondary expansion is not set.
1339 Moving things into the strcache also allows us to use const
1340 pointers in many more places.
1342 2007-01-03 Paul Smith <psmith@gnu.org>
1344 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1345 the function, not just the first. Fixes Savannah bug #18680.
1347 2006-11-18 Paul Smith <psmith@gnu.org>
1349 * strcache.c (strcache_add_len): Don't allocate a new buffer
1350 unless the string is not already nil-terminated. Technically this
1351 is a violation of the standard, since we may be passed an array
1352 that is not long enough to test one past. However, in make this
1353 is never true since we only use nil-terminated strings or
1354 sub-strings thereof.
1356 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1358 * main.c: New global cmd_prefix, defaults to '\t'.
1359 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1362 * dir.c: Constified.
1363 (dir_contents_file_exists_p): Check for an error return from
1364 readdir(), just in case.
1366 * commands.c: Constified.
1367 * default.c: Constified.
1368 * expand.c: Constified.
1369 * function.c: Partial constification.

1373 * vpath.c: Partial constification.
1374 * w32/pathstuff.c: Partial constification.
1376 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1378 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1379 backslashes and drive letters as absolute.
1381 2006-10-22 Paul Smith <psmith@gnu.org>
1383 * main.c (struct command_switch): Use const and void*.
1385 2006-10-21 Paul Smith <psmith@gnu.org>
1388 * arscan.c: Constified.
1390 2006-09-30 Paul Smith <psmith@gnu.org>
1392 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1393 point to lastword since the example was updated.
1394 Fixes Savannah bug #16304.
1395 (Secondary Expansion): Correct example description.
1396 Fixes Savannah bug #16468.
1397 (Makefile Contents): Clarify that comments cannot appear within
1398 variable references or function calls.
1399 Fixes Savannah bug #16577.
1400 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1401 Fixes Savannah bug #17701.
1402 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1403 (Prerequisite Types): Added an example of using order-only
1404 prerequisites. Fixes Savannah bug #17880.
1405 (Rule Syntax): "lise" -> "list"
1406 (Multiple Rules): ... -> @dots{}
1407 (Splitting Lines): ditto.
1409 * remake.c (update_file_1): Prereqs that don't exist should be
1410 considered changed, for the purposes of $?.
1411 Fixes Savannah bug #16051.
1413 * make.1: Remove extraneous "+".
1414 Fixes Savannah bug #16652.
1416 2006-09-06 Paul D. Smith <psmith@gnu.org>

1425 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1426 Normally, it is defined in config.h.
1428 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1431 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1432 sh_chars_sh for Windows platforms that emulate Unix.
1434 2006-05-07 Paul D. Smith <psmith@gnu.org>
1436 * README.OS2.template: Updates provided by Andreas Buening

1441 * make.h: Include <direct.h> if HAVE_DIRECT_H.

1453 that don't have extended grep.

1460 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1461 inner-scope variables don't mask outer-scope variables.
1463 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1465 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1466 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1467 values from memory allocation functions: they return void* and so
1468 don't need to be cast. Also remove (char *) casts of arguments to
1471 * configure.in: Remove checks for memcpy/memmove/strchr.
1473 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1475 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp

1483 2006-04-06 Paul D. Smith <psmith@gnu.org>
1485 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1486 require an ISO C 1989 standard compiler and runtime library.

1518 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1519 with lastslash, since the latter points to filename, not to

1522 Declare and define sh_chars_sh[].
1524 2006-03-23 Paul D. Smith <psmith@gnu.org>
1526 * configure.in: Look for build.sh.in in $srcdir so it will be
1527 built for remote configurations as well.
1529 * Makefile.am: Make sure to clean up build.sh during distclean.
1530 Fixes Savannah bug #16166.
1532 * misc.c (log_access): Takes a const char *.

1544 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1545 memory on hosts that don't support it directly.

1548 make sure I don't forget any).
1550 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1552 (die): Cleanup code was removed from here; call the new function.

1586 2006-03-09 Paul Smith <psmith@gnu.org>
1588 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1589 listed non-existent files as changed. Turns out there's a bug in
1590 the Linux kernel builds which means that this change causes
1591 everything to rebuild every time. We will re-introduce this fix
1592 in the next release, to give them time to fix their build system.
1593 Fixes Savannah bug #16002.
1594 Introduces Savannah bug #16051.
1596 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1597 we *don't* find UNIX "/".
1598 Reported by David Ergo <david.ergo@alterface.com>
1600 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1602 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1603 locator function find_and_set_default_shell if SHELL came from the
1606 2006-02-20 Paul D. Smith <psmith@gnu.org>
1608 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1609 to be null; don't core in that case.
1611 2006-02-19 Paul D. Smith <psmith@gnu.org>
1613 * commands.c (set_file_variables): Realloc, not malloc, the static
1614 string values to avoid memory leaks.
1616 * expand.c (recursively_expand_for_file): Only set reading_file to
1617 an initialized value.
1619 * implicit.c (pattern_search): We need to make a copy of the stem
1620 if we get it from an intermediate dep, since those get freed.
1622 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1624 (enter_file) [VMS]: Ditto.
1625 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1627 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1629 * job.c (construct_command_argv_internal): Fix last change.
1631 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1632 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1633 the calls to _beginthreadex.
1635 * expand.c (recursively_expand_for_file): Initialize `save' to
1636 prevent compiler warnings.
1638 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1640 * job.c (construct_command_argv_internal): Don't create a temporary
1641 script/batch file if we are under -n. Call _setmode to switch the
1642 script file stream to text mode.
1644 2006-02-17 Paul D. Smith <psmith@gnu.org>
1646 * variable.c (merge_variable_set_lists): Don't try to merge the
1647 global_setlist. Not only is this useless, but it can lead to
1648 circularities in the linked list, if global_setlist->next in one
1649 list gets set to point to another list which also ends in
1651 Fixes Savannah bug #15757.
1653 2006-02-15 Paul D. Smith <psmith@gnu.org>
1655 Fix for Savannah bug #106.
1657 * expand.c (expanding_var): Keep track of which variable we're
1658 expanding. If no variable is being expanded, it's the same as
1660 * make.h (expanding_var): Declare it.
1661 * expand.c (recursively_expand_for_file): Set expanding_var to the
1662 current variable we're expanding, unless there's no file info in
1663 it (could happen if it comes from the command line or a default
1664 variable). Restore it before we exit.
1665 * expand.c (variable_expand_string): Use the expanding_var file
1666 info instead of the reading_file info.
1667 * function.c (check_numeric): Ditto.
1669 (func_wordlist): Ditto.
1670 (func_error): Ditto.
1671 (expand_builtin_function): Ditto.
1672 (handle_function): Ditto.
1674 2006-02-14 Paul D. Smith <psmith@gnu.org>
1676 * read.c (eval): Even if the included filenames expands to the
1677 empty string we still need to free the allocated buffer.
1679 * implicit.c (pattern_search): If we allocated a variable set for
1680 an impossible file, free it.
1681 * variable.c (free_variable_set): New function.
1682 * variable.h: Declare it.
1684 * read.c (read_all_makefiles): Makefile names are kept in the
1685 strcache, so there's never any need to alloc/free them.
1688 * main.c (main): Add "archives" to the .FEATURES variable if
1689 archive support is enabled.
1690 * doc/make.texi (Special Variables): Document it.
1692 2006-02-13 Paul D. Smith <psmith@gnu.org>
1694 * implicit.c (pattern_search): Add checking for DOS pathnames to
1695 the pattern rule target LASTSLASH manipulation.

1700 * (ALL FILES): Updated copyright and license notices.
1702 2006-02-10 Paul D. Smith <psmith@gnu.org>
1704 A new internal capability: the string cache is a read-only cache
1705 of strings, with a hash table interface for fast lookup. Nothing
1706 in the cache will ever be freed, so there's no need for reference
1707 counting, etc. This is the beginning of a full solution for
1708 Savannah bug #15182, but for now we only store makefile names here.
1710 * strcache.c: New file. Implement a read-only string cache.
1711 * make.h: Add prototypes for new functions.
1712 * main.c (initialize_global_hash_tables): Initialize the string cache.
1713 (print_data_base): Print string cache stats.
1714 * read.c (eval_makefile): Use the string cache to store makefile
1715 names. Rewrite the string allocation to be sure we free everything.
1717 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1719 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1720 directory time stamp didn't change, except on FAT filesystems.
1721 Suggested by J. David Bryan <jdbryan@acm.org>.
1723 2006-02-09 Paul D. Smith <psmith@gnu.org>
1725 * function.c (func_or): Implement a short-circuiting OR function.
1726 (func_and): Implement a short-circuiting AND function.
1727 (function_table_init): Update the table with the new functions.
1728 * doc/make.texi (Conditional Functions): Changed the "if" section
1729 to one on general conditional functions. Added documentation for
1730 $(and ...) and $(or ...) functions.
1731 * NEWS: Note new $(and ...) and $(or ...) functions.
1733 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1735 * job.h (struct child): Add the dontcare bitfield.
1736 * job.c (new_job): Cache dontcare flag.
1737 * job.c (reap_children): Use cached dontcare flag instead of the
1738 one in struct file. Fixes Savannah bug #15641.
1740 2006-02-06 Paul D. Smith <psmith@gnu.org>
1742 * vpath.c (selective_vpath_search): If the file we find has a
1743 timestamp from -o or -W, use that instead of the real time.
1744 * remake.c (f_mtime): If the mtime is a special token from -o or
1745 -W, don't overwrite it with the real mtime.
1746 Fixes Savannah bug #15341.
1748 Updates from Markus Mauhart <qwe123@chello.at>:
1750 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1751 (process_signal, process_last_err, process_exit_code): Manage
1752 invalid handle values.
1753 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1754 manage invalid handles; remove them.

1756 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1757 * README.cvs: Updates for building from CVS.
1759 2006-02-05 Paul D. Smith <psmith@gnu.org>

1762 to avoid walking the list every time we want to add a new one.
1763 Fixes Savannah bug #15533.
1764 * filedef.h (struct file): Add a new LAST pointer.
1766 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1767 the comparison. For 64-bits systems the result of the subtraction
1768 might not fit into an int. Use comparison instead.
1769 Fixes Savannah bug #15534.
1771 * doc/make.texi: Update the chapter on writing commands to reflect
1772 the changes made in 3.81 for backslash/newline and SHELL handling.

1792 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1794 * remake.c (update_goal_chain): Set g->changed instead of
1795 incrementing it, as it is only 8-bit wide, and could overflow if
1796 many commands got started in update_file.
1798 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1800 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1801 MAXIMUM_WAIT_OBJECTS.
1802 (process_wait_for_any_private): Change dimension of handles[]
1803 array to MAXIMUM_WAIT_OBJECTS.
1804 (process_used_slots): New function.
1805 (process_register): Don't register more processes than the
1806 available number of slots.
1807 (process_easy): Don't start new processes if all slots are used up.
1809 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1810 are already more children than sub_proc.c can handle, behave as if
1811 the load were too high.
1812 (start_job_command): Fix a typo in error message when process_easy
1815 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1817 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1818 the shell is not sh.exe.
1820 * job.c (create_batch_file): Renamed from create_batch_filename;
1821 all callers changed. Don't close the temporary file; return its
1822 file descriptor instead. New arg FD allows to return the file
1824 (construct_command_argv_internal): Use _fdopen instead of fopen to
1825 open the batch file.
1827 2006-01-04 Paul D. Smith <psmith@gnu.org>
1829 * readme.vms: Updates for case-insensitive VMS file systems from
1830 Hartmut Becker <Hartmut.Becker@hp.com>.

1850 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1851 disable warnings for MSC.
1852 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1854 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1856 * doc/make.texi (Execution): Add a footnote about changes in
1857 handling of backslash-newline sequences. Mention the differences
1858 on MS-DOS and MS-Windows.
1860 * NEWS: More details about building the MinGW port and a pointer
1861 to README.W32. Fix the section name that describes the new
1862 backward-incompatible processing of backslash-newline sequences.
1863 The special processing of SHELL set to "cmd" is only relevant to
1864 MS-Windows, not MS-DOS.
1866 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1868 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1869 to DWORD, to avoid compiler warnings.
1870 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1871 use %ld in format, to avoid compiler warnings.

1885 * read.c (record_target_var): Initialize variable's export field
1886 with v_default instead of leaving it "initialized" by whatever
1887 garbage happened to be on the heap.

1891 * make.1: Fix some display errors and document all existing options.
1892 Patch by Mike Frysinger <vapier@gentoo.org>.
1894 2005-12-11 Paul D. Smith <psmith@gnu.org>
1896 * implicit.c (pattern_search): If 2nd expansion is not set for
1897 this implicit rule, replace the pattern with the stem directly,
1898 and don't re-expand the variable list. Along with the other
1899 .SECONDEXPANSION changes below, fixes bug #13781.
1901 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1903 * implicit.c (pattern_search): Mark other files that this rule
1904 builds as targets so that they are not treated as intermediates
1905 by the pattern rule search algorithm. Fixes bug #13022.
1907 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1909 * remake.c (notice_finished_file): Propagate the change of

1929 * read.c (record_files): Don't set deps flags if there are no deps.
1930 * maintMakefile: We only need to build the templates when we are
1931 creating a distribution, so don't do it for "all".
1933 2005-10-24 Paul D. Smith <psmith@gnu.org>
1935 Make secondary expansion optional: its enabled by declaring the
1936 special target .SECONDEXPANSION.
1938 * NEWS: Update information on second expansion capabilities.
1939 * doc/make.texi (Secondary Expansion): Document the
1940 .SECONDEXPANSION special target and its behavior.

1943 (free_dep_chain): Declare a prototype.
1944 * file.c (parse_prereqs): New function: break out some complexity
1946 (expand_deps): If we aren't doing second expansion, replace % with
1947 the stem for static pattern rules. Call the new function.
1948 * filedef.h (parse_prereqs): Declare a prototype.
1949 * implicit.c (pattern_search): Initialize the new staticpattern
1951 * main.c (second_expansion): Declare a global variable to remember
1952 if the special target has been seen. Initialize the new
1953 staticpattern field for prerequisites.
1954 * make.h: Extern for second_expansion.
1955 * misc.c (free_dep_chain): New function: frees a struct dep list.
1956 * read.c (read_all_makefiles): Initialize the staticpattern field.

1958 (record_files): Check for the .SECONDEXPANSION target and set
1959 second_expansion global if it's found.
1960 Use the new free_dep_chain() instead of doing it by hand.
1961 Set the staticpattern field for prereqs of static pattern targets.
1963 2005-10-16 Paul D. Smith <psmith@gnu.org>
1965 * main.c (main): Set CURDIR to be a file variable instead of a
1966 default, so that values of CURDIR inherited from the environment
1967 won't override the make value.
1969 2005-09-26 Paul D. Smith <psmith@gnu.org>
1971 * job.c (construct_command_argv_internal): If the line is empty
1972 remember to free the temporary argv strings.
1975 2005-09-16 Paul D. Smith <psmith@gnu.org>
1977 * job.c (start_job_command): The noerror flag is a boolean (single
1978 bit); set it appropriately.
1979 Reported by Mark Eichin <eichin@metacarta.com>
1981 2005-08-29 Paul D. Smith <psmith@gnu.org>
1983 * function.c (func_error): On Windows, output from $(info ...)
1984 seems to come in the wrong order. Try to force it with fflush().
1986 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1988 * read.c (record_files): Move code that sets stem for static
1989 pattern rules out of the if (!two_colon) condition so it is
1990 also executed for two-colon rules. Fixes Savannah bug #13881.
1992 2005-08-08 Paul D. Smith <psmith@gnu.org>
1994 * make.h: Don't test that __STDC__ is non-0. Some compilers
1995 (Windows for example) set it to 0 to denote "ISO C + extensions".
1998 2005-08-07 Paul D. Smith <psmith@gnu.org>
2000 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2001 conditional (slightly different version of a fix from Eli).
2003 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2004 If make is running in parallel without -k and two jobs die in a
2005 row, but not too close to each other, then make will quit without
2006 waiting for the rest of the jobs to die.
2008 * main.c (die): Don't reset err before calling reap_children() the
2009 second time: we still want it to be in the error condition.
2010 * job.c (reap_children): Use a static variable, rather than err,
2011 to control whether or not the error message should be printed.
2013 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2015 * w32/subproc/sub_proc.c: Include signal.h.
2016 (process_pipe_io, process_file_io): Pass a pointer to a local
2017 DWORD variable to GetExitCodeProcess. If the exit code is
2018 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2020 * job.c [WINDOWS32]: Include windows.h.
2021 (main_thread) [WINDOWS32]: New global variable.
2022 (reap_children) [WINDOWS32]: Get the handle for the main thread
2023 and store it in main_thread.
2025 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2026 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2027 doing anything else. When we are done, close the main thread
2028 handle and exit with status 130.
2030 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2032 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2035 * main.c (find_and_set_default_shell): If found a DOSish shell,
2036 set sh_found and the value of default_shell, and report the
2037 findings in debug mode.
2039 * job.c (construct_command_argv_internal): Check unixy_shell, not
2040 no_default_sh_exe, to decide whether to use Unixy or DOSish
2043 * README.W32: Update with info about the MinGW build.
2045 * build_w32.bat: Support MinGW.
2047 * w32/subproc/build.bat: Likewise.
2049 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2050 printing DWORD args.
2052 * function.c (windows32_openpipe): Fix format strings for printing
2055 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2057 (start_job_command): Fix format string for printing the result of
2059 (start_job_command) [WINDOWS32]: Do not define.
2060 (exec_command): Fix format string for printing HANDLE args.
2062 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2063 to avoid compiler warnings.
2064 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2065 (Note: some of these fixes were submitted independently by J. Grant)
2067 2005-07-30 J. Grant <jg@jguk.org>
2069 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2070 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.

2073 2005-07-15 Paul Smith <psmith@gnu.org>
2075 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2076 we don't have a POSIX shell, then revert to the old
2077 backslash-newline behavior (where they are stripped).
2080 2005-07-08 Paul D. Smith <psmith@gnu.org>
2082 * config.h.W32.template: Reorder to match the standard config.h,
2083 for easier comparisons.
2084 From J. Grant <jg@jguk.org>
2086 * maintMakefile: Remove .dep_segment before overwriting it, in
2087 case it's not writable or noclobber is set.
2088 * expand.c (variable_expand_string): Cast result of pointer
2089 arithmetic to avoid a warning.
2090 * main.c (switches): Add full-fledged final initializer.
2092 2005-07-06 Paul D. Smith <psmith@gnu.org>
2094 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2095 * signame.c (strsignal): If we found _sys_siglist[] or
2096 __sys_siglist[] use those instead of sys_siglist[].
2097 From Albert Chin <china@thewrittenword.com>
2099 2005-07-04 Paul D. Smith <psmith@gnu.org>
2101 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2102 globfree(); set up to use the GNU versions.
2103 From Martin Zinser <zinser@zinser.no-ip.info>

2113 * w32/subproc/build.bat: Ditto.
2115 2005-06-28 Paul D. Smith <psmith@gnu.org>
2117 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2118 declaration was checked but not present.
2120 2005-06-27 Paul D. Smith <psmith@gnu.org>
2122 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2123 to unsigned long. Fixes Savannah bug #13550.
2125 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2126 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2127 Fixes Savannah bug #13551.
2129 2005-06-26 Paul D. Smith <psmith@gnu.org>
2131 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2132 it if ANSI_STRING is not set.
2134 2005-06-25 Paul D. Smith <psmith@gnu.org>
2136 * read.c (eval): If no filenames are passed to any of the
2137 "include" variants, don't print an error.
2138 * doc/make.texi (Include): Document this.
2139 Fixes Savannah bug #1761.
2141 * job.c (construct_command_argv_internal): Sanitize handling of
2142 backslash/newline pairs according to POSIX: that is, keep the
2143 backslash-newline in the command script, but remove a following
2144 TAB character, if present. In the fast path, make sure that the
2145 behavior matches what the shell would do both inside and outside
2146 of quotes. In the slow path, quote the backslash and put a
2147 literal newline in the string.
2148 Fixes Savannah bug #1332.
2149 * doc/make.texi (Execution): Document the new behavior and give
2151 * NEWS: Make a note of the new behavior.
2153 * make.h [WINDOWS32]: #include <direct.h>.
2154 Fixes Savannah bug #13478.
2156 * remake.c (name_mtime): If the stat() of a file fails and the -L
2157 option was given and the file is a symlink, take the best mtime of
2158 the symlink we can get as the mtime of the file and don't fail.
2159 Fixes Savannah bug #13280.
2161 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2162 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2163 inside a variable reference. Make this function static as it's
2165 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2166 parsing an unexpanded line looking for semicolons.
2167 Fixes Savannah bug #1454.
2168 * misc.c (remove_comments): Move this to read.c and make it static
2169 as it's only used there. Call find_char_unquote() with new arg.
2170 * make.h: Remove prototypes for find_char_unquote() and
2171 remove_comments() since they're static now.
2173 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2174 its export flag and obtain its value. When we need to re-exec,
2175 increment the value and add it into the environment.
2176 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2177 * NEWS: Mention MAKE_RESTARTS.
2178 * main.c (always_make_set): New variable. Change the -B option to
2179 set this one instead.
2180 (main): When checking makefiles, only set always_make_flag if
2181 always_make_set is set AND the restarts flag is 0. When building
2182 normal targets, set it IFF always_make_set is set.
2183 (main): Avoid infinite recursion with -W, too: only set what-if
2184 files to NEW before we check makefiles if we've never restarted
2185 before. If we have restarted, set what-if files to NEW _after_ we
2187 Fixes Savannah bug #7566:
2189 2005-06-17 Paul D. Smith <psmith@gnu.org>
2191 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2192 in the prerequisites list.
2194 2005-06-12 Paul D. Smith <psmith@gnu.org>
2196 Fix Savannah bug # 1328.
2198 * configure.in: Check for atexit().
2199 * misc.c (close_stdout): Test stdout to see if writes to it have
2200 failed. If so, be sure to exit with a non-0 error code. Based on
2201 code found in gnulib.
2202 * make.h: Prototype.
2203 * main.c (main): Install close_stdout() with atexit().
2205 2005-06-10 Paul D. Smith <psmith@gnu.org>
2207 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2209 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2210 headers; make vmsWaitForChildren() static; extern vmsify().
2211 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2212 Don't create child_execute_job() here (it's in vmsjobs.c).
2213 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2215 2005-06-09 Paul D. Smith <psmith@gnu.org>
2217 * variable.c (push_new_variable_scope): File variables point
2218 directly to the global_setlist variable. So, inserting a new
2219 scope in front of that has no effect on those variables: they
2220 don't go through current_variable_set_list. If we're pushing a
2221 scope and the current scope is global, push it "the other way" so
2222 that the new setlist is in the global_setlist variable, and
2223 next points to a new setlist with the global variable set.
2224 (pop_variable_scope): Properly undo a push with the new
2226 Fixes Savannah bug #11913.
2228 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2230 * job.c (reap_children): Don't die of the command failed but
2231 the dontcare flag is set. Fixes Savannah bug #13216.
2233 * implicit.c (pattern_search): When creating a target from
2234 an implicit rule match, lookup pattern target and set precious
2235 flag in a newly created target. Fixes Savannah bug #13218.
2237 2005-05-13 Paul D. Smith <psmith@gnu.org>
2239 Implement "if... else if... endif" syntax.
2241 * read.c (eval): Push all checks for conditional words ("ifeq",
2242 "else", etc.) down into the conditional_line() function.
2243 (conditional_line): Rework to allow "else if..." clause. New
2244 return value -2 for lines which are not conditionals. The
2245 ignoring flag can now also be 2, which means "already parsed a
2246 true branch". If that value is seen no other branch of this
2247 conditional can be considered true. In the else parsing if there
2248 is extra text after the else, invoke conditional_line()
2249 recursively to see if it's another conditional. If not, it's an
2250 error. If so, raise the conditional value to this level instead
2251 of creating a new conditional nesting level. Special check for
2252 "else" and "endif", which aren't allowed on the "else" line.
2253 * doc/make.texi (Conditional Syntax): Document the new syntax.
2255 2005-05-09 Paul D. Smith <psmith@gnu.org>
2257 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2258 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2259 recurses to the w32 directory, even on non-Windows systems. Use
2260 the method suggested in the automake manual.
2261 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2262 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2264 2005-05-07 Paul D. Smith <psmith@gnu.org>
2266 * main.c (die): If we're dying with a fatal error (not that a
2267 command has failed), write back any leftover tokens before we go.
2269 * job.c (set_child_handler_action_flags): If there are jobs
2270 waiting for the load to go down, set an alarm to go off in 1
2271 second. This allows us to wake up from a potentially long-lasting
2272 read() and start a new job if the load has gone down. Turn it off
2274 (job_noop): Dummy signal handler function.
2275 (new_job): Invoke it with the new semantics.
2277 * docs/make.texi: Document secondary expansion. Various cleanups
2280 2005-05-03 Paul D. Smith <psmith@gnu.org>
2282 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2283 the targets which are to ultimately be made are called "goals";
2284 see the GNU make manual. Also, MAKECMDGOALS, etc.
2286 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2287 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2288 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2290 2005-05-02 Paul D. Smith <psmith@gnu.org>
2292 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2293 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2294 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2295 functions to vmsjobs.c. #include it into jobs.c.
2297 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2298 jobserver tokens. I found that this happens when an exported
2299 recursive variable contains a $(shell ...) function reference: in
2300 this situation we could "forget" to write back a token.
2302 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2303 we have. It's not reliable to depend on the number of children in
2304 our linked list so keep a separate count.
2305 (new_job): Check jobserver_tokens rather than children &&
2306 waiting_jobs. Increment jobserver_tokens when we get one.
2307 (free_child): If jobserver_tokens is 0, internal error. If it's
2308 >1, write a token back to the jobserver pipe (we don't write a
2309 token for the "free" job). Decrement jobserver_tokens.
2311 * main.c: Add variable master_job_slots.
2312 (main): Set it to hold the number of jobs requested if we're the
2313 master process, when using the jobserver.
2314 (die): Sanity checks: first test jobserver_tokens to make sure
2315 this process isn't holding any tokens we didn't write back.
2316 Second, if master_job_slots is set count the tokens left in the
2317 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2319 2005-04-24 Paul D. Smith <psmith@gnu.org>
2321 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2322 with -l# can lose jobserver tokens, because waiting jobs are not
2323 consulted properly when checking for the "free" token.
2325 * job.c (free_child): Count waiting_jobs as having tokens.
2326 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2327 handle jobs waiting for the load to drop.
2329 2005-04-23 Paul D. Smith <psmith@gnu.org>
2331 * main.c (main): Be careful to not core if a variable setting in
2332 the environment doesn't contain an '='. This is illegal but can
2333 happen in broken setups.
2334 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2336 2005-04-12 Paul D. Smith <psmith@gnu.org>
2338 The second expansion feature causes significant slowdown. Timing
2339 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2340 read the makefile before the feature, to 11+s to do the same
2341 operations after the feature. Additionally, memory usage
2342 increased drastically. To fix this I added some intelligence that
2343 avoids the overhead of the second expansion unless it's required.
2345 * dep.h: Add a new boolean field, need_2nd_expansion.
2347 * read.c (eval): When creating the struct dep for the target,
2348 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2349 (record_files): If there's a "%" in a static pattern rule, it gets
2350 converted to "$*" so set need_2nd_expansion to 1.
2352 * file.c (expand_deps): Rework to be more efficient. Only perform
2353 initialize_file_variables(), set_file_variables(), and
2354 variable_expand_for_file() if the need_2nd_expansion is set.
2356 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2357 (pattern_search): Ditto.
2358 * main.c (handle_non_switch_argument): Ditto.
2360 * read.c (read_all_makefiles): Ditto.
2361 (eval_makefile): Ditto.
2363 2005-04-07 Paul D. Smith <psmith@gnu.org>
2365 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2366 * variable.c (sync_Path_environment): Ditto.
2367 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2369 * main.c (main): Define the .FEATURES variable.
2370 * NEWS: Announce .FEATURES.
2371 * doc/make.texi (Special Variables): Document .FEATURES.
2373 * remake.c (check_dep): If a file is .PHONY, update it even if
2374 it's marked intermediate. Fixes Savannah bug #12331.
2376 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2378 * file.c (expand_deps): Factor out the second expansion and
2379 prerequisite line parsing logic from snap_deps().
2381 * file.c (snap_deps): Use expand_deps(). Expand and parse
2382 prerequisites of the .SUFFIXES special target first. Fixes
2383 Savannah bug #12320.
2385 2005-03-13 Paul D. Smith <psmith@gnu.org>
2387 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2390 2005-03-11 Paul D. Smith <psmith@gnu.org>
2392 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2393 available, not undefined (from Earnie Boyd).
2395 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2397 * implicit.c (pattern_search): Mark an intermediate target as
2398 precious if it happened to be a prerequisite of some (other)
2399 target. Fixes Savannah bug #12267.
2401 2005-03-09 Paul D. Smith <psmith@gnu.org>
2403 * read.c (eval_makefile): Add alloca(0).
2404 (eval_buffer): Ditto.
2406 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2408 * main.c (main): Use o_file instead of o_default when defining
2409 the .DEFAULT_TARGET special variable.
2410 * read.c (eval): Use define_variable_global() instead of
2411 define_variable() when setting new value for the .DEFAULT_TARGET
2412 special variable. Fixes Savannah bug #12266.
2414 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2416 * imlicit.c (pattern_search): Mark files for which an implicit
2417 rule has been found as targets. Fixes Savannah bug #12202.
2419 2005-03-04 Paul D. Smith <psmith@gnu.org>
2422 * doc/make.texi (Automatic Variables): Document $|.
2424 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2426 * read.c (record_files): Instead of substituting % with
2427 actual stem value in dependency list replace it with $*.
2428 This fixes stem triple expansion bug.
2430 * implicit.c (pattern_search): Copy stem to a separate
2431 buffer and make it a properly terminated string. Assign
2432 this buffer instead of STEM (which is not terminated) to
2433 f->stem. Instead of substituting % with actual stem value
2434 in dependency list replace it with $*. This fixes stem
2435 triple expansion bug.
2437 2005-03-01 Paul D. Smith <psmith@gnu.org>
2439 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2440 on Windows, as it takes a handle not a pid. Just exit.
2441 Fix from patch #3679, provided by Alessandro Vesely.
2443 * configure.in: Update check for sys_siglist[] from autoconf manual.
2444 * signame.c (strsignal): Update to use the new autoconf macro.
2446 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2448 * read.c (record_files): Add a check for the list of prerequisites
2449 of a static pattern rule being empty. Fixes Savannah bug #12180.
2451 2005-02-28 Paul D. Smith <psmith@gnu.org>
2453 * doc/make.texi (Text Functions): Update docs to allow the end
2454 ordinal for $(wordlist ...) to be 0.
2455 * function.c (func_wordlist): Fail if the start ordinal for
2456 $(wordlist ...) is <1. Matches documentation.
2457 Resolves Savannah support request #103195.
2459 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2460 previously we were stopping when !-q, exactly the opposite. This
2461 has been wrong since version 1.34, in 1994!
2462 (update_file): If we got an error don't break out to run more
2463 double-colon rules: just return immediately.
2464 Fixes Savannah bug #7144.
2466 2005-02-27 Paul D. Smith <psmith@gnu.org>
2468 * misc.c (end_of_token): Make argument const.
2469 * make.h: Update prototype.
2471 * function.c (abspath, func_realpath, func_abspath): Use
2472 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2473 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2474 * read.c (record_files): Ditto.
2475 * variable.c (do_variable_definition): Ditto.
2477 * function.c (func_error): Create a new function $(info ...) that
2478 simply prints the message to stdout with no extras.
2479 (function_table_init): Add new function to the table.
2480 * NEWS: Add $(info ...) reference.
2481 * doc/make.texi (Make Control Functions): Document it.
2483 New feature: if the system supports symbolic links, and the user
2484 provides the -L/--check-symlink-time flag, then use the latest
2485 mtime between the symlink(s) and the target file.
2487 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2488 readlink(). If both are available, define MAKE_SYMLINKS.
2489 * main.c: New variable: check_symlink_flag.
2490 (usage): Add a line for -L/--check-symlink-times to the help string.
2491 (switches): Add -L/--check-symlink-times command line argument.
2492 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2493 print a warning and disable it again.
2494 * make.h: Declare check_symlink_flag.
2495 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2496 if the file is a symlink then check each link in the chain and
2497 choose the NEWEST mtime we find as the mtime for the file. The
2498 newest mtime might be the file itself!
2499 * NEWS: Add information about this new feature.
2500 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2502 Avoid core dumps described in Savannah bug # 12124:
2504 * file.c: New variable snapped_deps remember whether we've run
2506 (snap_deps): Set it.
2507 * filedef.h: Extern it.
2508 * read.c (record_files): Check snapped_deps; if it's set then
2509 we're trying to eval a new target/prerequisite relationship from
2510 within a command script, which we don't support. Fatal.
2512 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2514 Implementation of the .DEFAULT_TARGET special variable.
2516 * read.c (eval): If necessary, update default_target_name when
2518 * read.c (record_files): Update default_target_file if
2519 default_target_name has changed.
2520 * main.c (default_target_name): Define.
2521 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2522 default_target_name is set use default_target_file as a root
2524 * filedef.h (default_target_name): Declare.
2525 * dep.h (free_dep_chain):
2526 * misc.c (free_dep_chain): Change to operate on struct nameseq
2527 and change name to free_ns_chain.
2528 * file.c (snap_deps): Update to use free_ns_chain.
2530 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2532 Implementation of the second expansion in explicit rules,
2533 static pattern rules and implicit rules.
2535 * read.c (eval): Refrain from chopping up rule's dependencies.
2536 Store them in a struct dep as a single dependency line. Remove
2537 the code that implements SySV-style automatic variables.
2539 * read.c (record_files): Adjust the code that handles static
2540 pattern rules to expand all percents instead of only the first
2541 one. Reverse the order in which dependencies are stored so that
2542 when the second expansion reverses them again they appear in
2543 the makefile order (with some exceptions, see comments in
2544 the code). Remove the code that implements SySV-style automatic
2547 * file.c (snap_deps): Implement the second expansion and chopping
2548 of dependency lines for explicit rules.
2550 * implicit.c (struct idep): Define an auxiliary data type to hold
2551 implicit rule's dependencies after stem substitution and
2554 * implicit.c (free_idep_chain): Implement.
2556 * implicit.c (get_next_word): Implement helper function for
2557 parsing implicit rule's dependency lines into words taking
2558 into account variable expansion requests. Used in the stem
2561 * implicit.c (pattern_search): Implement the second expansion
2562 for implicit rules. Also fixes bug #12091.
2564 * commands.h (set_file_variables): Declare.
2565 * commands.c (set_file_variables): Remove static specifier.
2567 * dep.h (free_dep_chain): Declare.
2568 * misc.c (free_dep_chain): Implement.
2570 * variable.h (variable_expand_for_file): Declare.
2571 * expand.c (variable_expand_for_file): Remove static specifier.
2573 * make.h (strip_whitespace): Declare.
2574 * function.c (strip_whitespace): Remove static specifier.
2576 2005-02-26 Paul D. Smith <psmith@gnu.org>
2578 * main.c (main): Check for ferror() when reading makefiles from stdin.
2579 Apparently some shells in Windows don't close pipes properly and
2582 2005-02-24 Jonathan Grant <jg@jguk.org>
2584 * configure.in: Add MinGW configuration options, and extra w32 code
2586 * Makefile.am: Add MinGW configuration options, and extra w32 code
2588 * main.c: Determine correct program string (after last \ without .exe).
2589 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2591 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2592 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2593 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2594 environment support.
2596 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2598 * function.c (func_shell): When initializing error_prefix, check
2599 that reading file name is not null. This fixes long-standing
2600 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2602 2005-02-09 Paul D. Smith <psmith@gnu.org>
2604 * maintMakefile: Update the CVS download URL to simplify them.
2605 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2606 downloading the .texi files from Savannah now.
2608 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2610 * main.c (handle_non_switch_argument): Only add variables to
2611 command_variables if they're not already there: duplicate settings
2612 waste space and can be confusing to read.
2614 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2615 this header is never included by non-WINDOWS32 code, and it
2616 requires <config.h> to define which isn't always included first.
2618 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2619 testing MINGW32 versions.
2621 * main.c (log_working_directory): flush stdout to be sure the WD
2622 change is printed before any stderr messages show up.
2624 2005-02-01 Paul D. Smith <psmith@gnu.org>
2626 * maintMakefile (po_repo): Update the GNU translation site URL.
2628 2004-12-01 Paul D. Smith <psmith@gnu.org>
2630 * main.c (main): Change char* env_shell to struct variable shell_var.
2631 * variable.c (target_environment): Use new shell_var.
2633 2004-11-30 Paul D. Smith <psmith@gnu.org>
2635 * configure.in: The old way we avoided creating build.sh from
2636 build.sh.in before build.sh.in exists doesn't work anymore; we
2637 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2638 the help!). This also keeps automake from complaining.
2639 * Makefile.am (README): Add a dummy target so automake won't
2640 complain that this file doesn't exist when we checkout from CVS.
2641 * maintMakefile (.dep_segment): Rewrite this rule since newer
2642 versions of automake don't provide DEP_FILES.
2644 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2646 Implementation of `realpath' and `abspath' built-in functions.
2648 * configure.in: Check for realpath.
2649 * function.c (abspath): Return an absolute file name that does
2650 not contain any `.' or `..' components, nor repeated `/'.
2651 * function.c (func_abspath): For each name call abspath.
2652 * function.c (func_realpath): For each name call realpath
2653 from libc or delegate to abspath if realpath is not available.
2654 * doc/make.texi (Functions for File Names): Document new functions.
2655 * doc/make.texi (Quick Reference): Ditto.
2657 2004-11-28 Paul D. Smith <psmith@gnu.org>
2659 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2660 arguments. Fixes bug #10252.
2662 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2664 * main.c (main): Set SHELL to v_noexport by default. Remember the
2665 original environment setting of SHELL in the env_shell variable.
2666 * main.h: Export new env_shell variable.
2667 * variable.c (target_environment): If we find a v_noexport
2668 variable for SHELL, add a SHELL variable with the env_shell value.
2669 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2670 * doc/make.texi (Variables/Recursion): Ditto.
2672 2004-11-28 Paul D. Smith <psmith@gnu.org>
2674 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2675 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2676 Patch by Alessandro Vesely.
2678 2004-11-12 Paul D. Smith <psmith@gnu.org>
2680 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2681 the command line if it's inside a string.
2682 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2684 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2686 * function.c (func_lastword): New function: return last word
2687 from the list of words.
2688 * doc/make.texi: Document $(lastword ). Fix broken links in
2689 Quick Reference section.
2691 2004-10-06 Paul D. Smith <psmith@gnu.org>
2693 Apply patch from Alessandro Vesely, provided with bug # 9748.
2694 Fix use of tmpnam() to work with Borland C.
2696 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2697 construction of a temporary filename, and call new function
2698 create_batch_filename().
2699 (create_batch_filename) [WINDOWS32]: New function to create a
2702 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2704 * read.c (record_target_var): Expand simple pattern-specific
2706 * variable.c (initialize_file_variables): Do not expand simple
2707 pattern-specific variable.
2709 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2711 * remake.c (update_file_1): When rebuilding makefiles inherit
2712 dontcare flag from a target that triggered update.
2714 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2716 * variable.c (initialize_file_variables): Mark pattern-specific
2717 variable as a per-target and copy export status.
2719 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2721 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2723 * implicit.c (pattern_search): When considering an implicit rule's
2724 prerequisite check that it is actually a target rather then
2725 just an entry in the file hashtable.
2727 2004-09-21 Paul D. Smith <psmith@gnu.org>
2729 * read.c (readstring): Fix some logic errors in backslash handling.
2730 (eval): Remove some unnecessary processing in buffer handling.
2731 (record_target_var): Assert that parse_variable_definition() succeeded.
2732 Reported by: Markus Mauhart <qwe123@chello.at>.
2734 * misc.c: Removed the sindex() function. All instances of this
2735 function were trivially replaceable by the standard strstr()
2736 function, and that function will always have better (or certainly
2737 no worse) performance than the very simple-minded algorithm
2738 sindex() used. This can matter with complex makefiles.
2739 * make.h: Remove the prototype for sindex().
2740 * function.c (subst_expand): Convert sindex() call to strstr().
2741 This means we no longer need to track the TLEN value so remove that.
2742 (func_findstring): Convert sindex() to strstr().
2743 * commands.c (chop_commands): Convert sindex() calls to strstr().
2744 Suggested by: Markus Mauhart <qwe123@chello.at>.
2746 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2747 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2748 If SHELL is set to CMD.EXE then assume it's batch-mode and
2749 non-unixy. I wrote the code differently from the patch, though,
2750 to make it safer. This also resolves bug #9174.
2752 2004-09-20 Paul D. Smith <psmith@gnu.org>
2754 * expand.c (variable_expand_string): Modify to invoke
2755 patsubst_expand() instead of subst_expand(); the latter didn't
2756 handle suffix patterns correctly.
2757 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2758 was used only from variable_expand_string() and is no longer used
2760 (func_subst): Ditto, on call to subst_expand().
2761 (patsubst_expand): Require the percent pointers to point to the
2762 character after the %, not to the % itself.
2763 * read.c (record_files): New call criteria for patsubst_expand().
2764 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2765 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2767 2004-09-19 Paul D. Smith <psmith@gnu.org>
2769 * function.c (subst_expand): Fix a check in by_word: look for a
2770 previous blank if we're beyond the beginning of the string, not
2771 the beginning of the word.
2772 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2774 2004-05-16 Paul D. Smith <psmith@gnu.org>
2776 * remake.c (update_goal_chain): Change the argument specifying
2777 whether we're rebuilding makefiles to be a global variable,
2778 REBUILDING_MAKEFILES.
2779 (complain): Extract the code that complains about no rules to make
2780 a target into a separate function.
2781 (update_file_1): If we tried to rebuild a file during the makefile
2782 rebuild phase and it was dontcare, then no message was printed.
2783 If we then try to build the same file during the normal build,
2784 print a message this time.
2785 (remake_file): Don't complain about un-remake-able files when
2786 we're rebuilding makefiles.
2788 2004-05-11 Paul D. Smith <psmith@gnu.org>
2790 * job.c (construct_command_argv_internal): OS/2 patches from
2791 Andreas Buening <andreas.buening@nexgo.de>.
2793 2004-05-10 Paul D. Smith <psmith@gnu.org>
2795 * remake.c (update_file): Don't walk the double-colon chain unless
2796 this is a double-colon rule. Fix suggested by Boris Kolpackov
2797 <boris@kolpackov.net>.
2799 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2800 * readme.vms: New section describing OpenVMS support and issues.
2801 * default.c (default_variables): Add support for IA64.
2802 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2803 without some privilege aborts make with the error
2804 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2805 pressing Ctrl+Y and the input device is no terminal. The change
2806 catches this error and just continues.
2808 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2810 2004-04-25 Paul D. Smith <psmith@gnu.org>
2812 * commands.c (set_file_variables): Set $< properly in the face of
2813 order-only prerequisites.
2814 Patch from Boris Kolpackov <boris@kolpackov.net>
2816 2004-04-21 Bob Byrnes <byrnes@curl.com>
2818 * main.c (main): Notice failures to remake makefiles.
2820 2004-03-28 Paul D. Smith <psmith@gnu.org>
2822 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2824 * job.c: No default shell for RISC OS.
2825 (load_too_high): Hard-code the return to 1.
2826 (construct_command_argv_internal): No sh_chars or sh_cmds.
2827 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2829 2004-03-20 Paul D. Smith <psmith@gnu.org>
2831 * variable.c (do_variable_definition): Don't append from the
2832 global set if a previous non-appending target-specific variable
2833 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2836 * expand.c (reference_variable): Don't give up on variables with
2837 no value that have the target-specific append flag set: they might
2838 have a value after all. Reported by Oliver Schmidt
2839 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2840 <nikulin@dx1cmd.inp.nsk.su>.
2842 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2843 refer to absolute pathnames in directories that don't exist: some
2844 portion of the makefile could create those directories before we
2845 match the pattern. Fixes bugs #775 and #108.
2847 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2849 * main.c (main): Free makefile_mtimes if we have any.
2850 * README.W32.template: Update documentation for the current status
2851 of the MS-Windows port.
2852 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2853 environment variable is sometimes already defined which causes the
2855 * main.c (debug_signal_handler): Only define this function if
2856 SIGUSR1 is available.
2858 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2860 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2861 * README.OS2.template: Documentation updates.
2862 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2863 link line for safety.
2864 * maintMakefile (build.sh.in): Remove an extraneous ")".
2865 * job.c (child_execute_job): Close saved FDs.
2866 * job.c (exec_command) [OS/2]: exec_command(): If the command
2867 can't be exec'ed and if the shell is not Unix-sh, then try again
2868 with argv = { "cmd", "/c", ... }. Normally, this code is never
2869 reached for the cmd shell unless the command really doesn't exist.
2870 (construct_command_argv_internal) [OS/2]: The code for cmd
2871 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2872 The CMD builtin commands are case insensitive so use strcasecmp().
2874 2004-03-19 Paul D. Smith <psmith@gnu.org>
2876 * read.c (do_define): Re-order line counter increment so the count
2877 is accurate (we were losing one line per define). Reported by
2878 Dave Yost <Dave@Yost.com>.
2880 2004-03-06 Paul D. Smith <psmith@gnu.org>
2882 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2884 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2885 * misc.c (message,error,fatal): Ditto.
2886 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2887 * config.h.W32.template: Ditto.
2888 * config.h-vms.template: Ditto.
2889 * config.ami.template: Ditto.
2891 2004-03-04 Paul D. Smith <psmith@gnu.org>
2893 * README.template: Add a note about broken /bin/sh on SunOS
2894 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2896 * misc.c (message, error, fatal): Don't use "..." if we're using
2897 varargs. ansi2knr should handle this but it doesn't work: it
2898 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2899 done. On many systems (SunOS for example) va_dcl is a #define.
2900 So, force the use of the non-"..." version on pre-ANSI compilers.
2902 * maintMakefile (sign-dist): Create some rules to help automate
2903 the new GNU ftp upload method.
2905 2004-02-24 Paul D. Smith <psmith@gnu.org>
2907 * config.h.W32.template: Add HAVE_STDARG_H
2908 * config.h-vms.template: Ditto.
2909 * config.ami.template: Ditto.
2911 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2913 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2914 * build_w32.bat: Remove extra "+".
2916 2004-02-23 Paul D. Smith <psmith@gnu.org>
2918 * make.h: Create an UNUSED macro to mark unused parameters.
2919 * (many): Clean up warnings by applying UNUSED, fixing
2920 signed/unsigned incompatibilities, etc.
2922 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2924 * filedef.h: Name the command_state enumeration.
2925 * file.c (set_command_state): Use the enumeration in the function
2928 * configure.in: Explicitly set SET_MAKE to empty, to disable
2929 MAKE=make even when no make already exists. Fix bug #3823.
2931 2004-02-22 Paul D. Smith <psmith@gnu.org>
2933 * maintMakefile: Perl script to clean up all non-CVS files. Use
2934 it on all the subdirectories for the cvs-clean target.
2936 * main.c (decode_switches): Require non-empty strings for all our
2937 string command-line options. Fixes Debian bug # 164165.
2939 * configure.in: Check for stdarg.h and varargs.h.
2940 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2941 for printing messages.
2942 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2947 A number of patches for OS/2 support from Andreas Buening
2948 <andreas.buening@nexgo.de>:
2950 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2951 disable the SIGCHLD handler.
2952 (reap_children) [OS/2]: Remove special handling of job_rfd.
2953 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2954 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2955 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2956 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2957 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2960 2004-02-21 Paul D. Smith <psmith@gnu.org>
2962 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2963 <mail@kristov.de> reports that if process_begin() fails we don't
2964 handle the error condition correctly in all cases.
2965 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2966 to have a newline on the message.
2968 * job.c (construct_command_argv_internal): Add "test" to UNIX
2969 sh_cmds[]. Fixes Savannah bug # 7606.
2971 2004-02-04 Paul D. Smith <psmith@gnu.org>
2973 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2974 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2975 Hartmut Becker <Hartmut.Becker@hp.com>.
2977 2004-01-21 Paul D. Smith <psmith@gnu.org>
2979 * job.c (load_too_high): Implement an algorithm to control the
2980 "thundering herd" problem when using -l to control job creation
2981 via the load average. The system only recomputes the load once a
2982 second but we can start many jobs in a second. To solve this we
2983 keep track of the number of jobs started in the last second and
2984 apply a weight to try to guess what a correct load would be.
2985 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2986 Also fixes bug #4693.
2987 (reap_children): Decrease the job count for this second.
2988 (start_job_command): Increase the job count for this second.
2990 * read.c (conditional_line): Expand the text after ifn?def before
2991 checking to see if it's a single word. Fixes bug #7257.
2993 2004-01-09 Paul D. Smith <psmith@gnu.org>
2995 * file.c (print_file): Recurse to print all targets in
2996 double-colon rules. Fixes bug #4518, reported (with patch) by
2997 Andrew Chatham <chatham@google.com>.
2999 2004-01-07 Paul D. Smith <psmith@gnu.org>
3001 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3002 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3003 AC_FUNC_SETVBUF_REVERSED.
3005 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3006 (MAKE Variable): Fix Savannah bug #4898.
3008 * job.c (construct_command_argv_internal): Add "!" to the list of
3009 shell escape chars. POSIX sh allows it to appear before a
3010 command, to negate the exit code. Fixes bug #6404.
3012 * implicit.c (pattern_search): When matching an implicit rule,
3013 remember which dependencies have the ignore_mtime flag set.
3014 Original fix provided in Savannah patch #2349, by Benoit
3015 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3017 2003-11-22 Paul D. Smith <psmith@gnu.org>
3019 * README.W32.template (Outputs): Clarification on -j with
3020 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3023 2003-11-02 Paul D. Smith <psmith@gnu.org>
3025 * function.c (func_if): Strip all the trailing whitespace from the
3026 condition, then don't expand it. Fixed bug # 5798.
3028 * expand.c (recursively_expand_for_file): If we're expanding a
3029 variable with no file context, then use the variable's context.
3032 2003-10-21 Paul D. Smith <psmith@gnu.org>
3034 * main.c (log_working_directory): Add newlines to printf()s.
3036 * README.cvs: Add a note to ignore warnings during autoreconf.
3038 * maintMakefile (po_repo): Set a new URL for PO file updates.
3039 (get-config/config.guess get-config/config.sub): Get these files
3040 from the Savannah config project instead of ftp.gnu.org.
3042 2003-10-05 Paul Eggert <eggert@twinsun.com>
3044 * main.c (main): Avoid potential subscript error if environ has
3047 2003-08-22 Paul D. Smith <psmith@gnu.org>
3049 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3050 systems which don't yet implement the C89 standard :-/.
3052 2003-07-18 Paul D. Smith <psmith@gnu.org>
3054 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3055 [WINDOWS32]: Initialize hash.
3057 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3059 * dir.c (read_dirstream): Provide a workaround for broken versions of
3060 the MinGW dirent structure.
3062 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3064 * w32/include/dirent.h: Add __MINGW32__ filter.
3066 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3068 * make.h: Add global declaration of *make_host.
3069 * main.c (print_usage): Remove local declaration of *make_host.
3070 (print_version): Display "This program built for ..." after Copyright
3073 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3075 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3076 execution of "makeinfo --html make.texi".
3078 2003-04-30 Paul D. Smith <psmith@gnu.org>
3080 * build.template: Make some changes to maybe allow this script to
3081 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3083 * README.OS2.template: New file for OS/2 support. Original
3084 contributed by Andreas Buening.
3085 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3088 2003-04-19 Paul D. Smith <psmith@gnu.org>
3090 Fix bug #1405: allow a target to match multiple pattern-specific
3093 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3094 variable.c, where they've always belonged.
3095 * rule.h: Move the prototypes and struct pattern_var as well.
3096 * variable.c (initialize_file_variables): Invoke
3097 lookup_pattern_var() in a loop, until no more matches are found.
3098 If a match is found, create a new variable set for the target's
3099 pattern variables. Then merge the contents of each matching
3100 pattern variable set into the target's pattern variable set.
3101 (lookup_pattern_var): Change this function to be usable
3102 in a loop. It takes a starting position: if NULL, start at the
3103 beginning; if non-NULL, start with the pattern variable after that
3104 position, and return the next matching pattern.
3105 (create_pattern_var): Create a unique instance of
3106 pattern-specific variables for every definition in the makefile.
3107 Don't combine the same pattern together. This allows us to
3108 process the variable handling properly even when the same pattern
3109 is used multiple times.
3110 (parse_variable_definition): New function: break out the parsing
3111 of a variable definition line from try_variable_definition.
3112 (try_variable_definition): Call parse_variable_definition to
3114 (print_variable_data_base): Print out pattern-specific variables.
3115 * variable.h (struct variable): Remember when a variable is
3116 conditional. Also remember its flavor.
3117 (struct pattern_var): Instead of keeping a variable set, we just
3118 keep a single variable for each pattern.
3119 * read.c (record_target_var): Each pattern variable contains only a
3120 single variable, not a set, so create it properly.
3121 * doc/make.texi (Pattern-specific): Document the new behavior.
3123 2003-04-17 Paul D. Smith <psmith@gnu.org>
3125 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3126 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3127 file/directory naming rules for VMS so I can't tell whether this
3130 2003-04-09 Paul D. Smith <psmith@gnu.org>
3132 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3133 DOS-style pathnames: backslash separators and drive specifiers.
3135 2003-03-28 Paul D. Smith <psmith@gnu.org>
3137 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3138 the intermediate flag on all targets. Fixes bug #2515.
3140 2003-03-24 Paul D. Smith <psmith@gnu.org>
3142 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3143 Upgrade to autoconf 2.57 and automake 1.7.3.
3145 * job.c: More OS/2 changes from Andreas Buening.
3147 * file.c (print_file): Fix variable initialization.
3150 * remake.c (notice_finished_file):
3152 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3153 some calls (like readdir()) return NULL in valid situations
3154 without resetting errno. Fixes bug #2846.
3156 2003-02-25 Paul D. Smith <psmith@gnu.org>
3158 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3160 * job.c (_is_unixy_shell) [OS/2]: New function.
3161 Set default shell to /bin/sh.
3162 (reap_children): Close the job_rfd pipe here since we don't use a
3164 (set_child_handler_action_flags): define this to empty on OS/2.
3165 (start_job_command): Close the jobserver pipe and use
3166 child_execute_job() instead of fork/exec.
3167 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3168 rather than exec'ing, then reconfigure stdin/stdout.
3169 (exec_command): Rewrite to use spawn instead of exec. Return the
3172 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3173 in DOS. Handle the TEMP environment variable as in DOS. Don't
3174 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3175 use -j in DOS mode. Use child_execute_job() instead of
3178 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3181 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3182 prototypes that return values.
3184 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3186 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3187 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3189 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3192 2003-02-24 Paul D. Smith <psmith@gnu.org>
3194 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3195 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3196 (child_execute_job) [VMS]: Handle error status properly.
3197 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3199 * function.c (func_shell): Use EINTRLOOP() while reading from the
3200 subshell pipe (Fixes bug #2502).
3201 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3203 * main.c (main): Ditto.
3205 2003-01-30 Paul D. Smith <psmith@gnu.org>
3207 * read.c (eval): eval() was not fully reentrant, because the
3208 collapsed buffer was static. Change it to be an automatic
3209 variable so that eval() can be invoked recursively.
3211 (eval): Apply patch # 1022: fix memory reference error on long
3212 target-specific variable lines.
3213 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3215 * function.c (check_numeric): Combine the is_numeric() function
3216 into this function, since it's only called from one place.
3217 Constify this function. Have it print the incorrect string in the
3218 error message. Fixes bug #2407.
3219 (strip_whitespace): Constify.
3220 (func_if): Constify.
3221 * expand.c (expand_argument): Constify.
3223 2003-01-29 Paul D. Smith <psmith@gnu.org>
3225 Fix bug # 2169, also reported by other people on various systems.
3227 * make.h: Some systems, such as Solaris and PTX, do not fully
3228 implement POSIX-compliant SA_RESTART functionality; important
3229 system calls like stat() and readdir() can still fail with EINTR
3230 even if SA_RESTART has been set on the signal handler. So,
3231 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3232 EINTR for system calls which return -1 or 0 (NULL), respectively,
3234 Also, remove the old atomic_stat()/atomic_readdir() and
3235 HAVE_BROKEN_RESTART handling.
3237 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3239 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3240 * remake.c (touch_file): Ditto.
3242 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3243 * read.c (construct_include_path): Ditto.
3244 * remake.c (name_mtime): Ditto.
3245 * vpath.c (selective_vpath_search): Ditto.
3246 * dir.c (find_directory): Ditto.
3247 (local_stat): Ditto.
3248 (find_directory): Use ENULLLOOP() to wrap opendir().
3249 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3251 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3252 atomic_readdir() handling.
3254 2003-01-22 Paul D. Smith <psmith@gnu.org>
3256 * function.c (func_call): Fix Bug #1744. If we're inside a
3257 recursive invocation of $(call ...), mask any of the outer
3258 invocation's arguments that aren't used by this one, so that this
3259 invocation doesn't "inherit" them accidentally.
3261 2002-12-05 Paul D. Smith <psmith@gnu.org>
3263 * function.c (subst_expand): Valery Khamenia reported a
3264 pathological performance hit when doing substitutions on very
3265 large values with lots of words: turns out we were invoking
3266 strlen() a ridiculous number of times. Instead of having each
3267 call to sindex() call strlen() again, keep track of how much of
3268 the text we've seen and pass the length to sindex().
3270 2002-11-19 Paul D. Smith <psmith@gnu.org>
3272 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3275 2002-11-16 Paul D. Smith <psmith@gnu.org>
3277 * NMakefile.template (OBJS): Add hash.c object file.
3278 * SMakefile.template (srcs): Ditto.

3280 * build_w32.bat: Ditto.
3282 * Makefile.DOS.template: Remove extra dependencies.
3284 2002-10-25 Paul D. Smith <psmith@gnu.org>
3286 * expand.c (install_variable_buffer): New function. Install a new
3287 variable_buffer context and return the previous one.
3288 (restore_variable_buffer): New function. Free the current
3289 variable_buffer context and put a previously saved one back.
3290 * variable.h: Prototypes for {install,restore}_variable_buffer.
3291 * function.c (func_eval): Push a new variable_buffer context
3292 before we eval, then restore the old one when we're done.
3295 * read.c (install_conditionals): New function. Install a new
3296 conditional context and return the previous one.
3297 (restore_conditionals): New function. Free the current
3298 conditional context and put a previously saved one back.
3299 (eval): Use the {install,restore}_conditionals for "include"
3301 (eval_buffer): Use {install,restore}_conditionals to preserve the
3302 present conditional state before we evaluate the buffer.
3305 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3307 (Recursion): Add a variable index entry for CURDIR.
3309 * README.cvs: Update to appropriate versions.
3310 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3311 don't need to copy loadavg.c: automake is smart enough to create
3312 it for me. Still have a bug in automake related to ansi2knr tho.
3314 2002-10-14 Paul D. Smith <psmith@gnu.org>
3316 * remake.c (notice_finished_file): Only touch targets if they have
3317 at least one command (as per POSIX). Resolve Bug #1418.
3319 * *.c: Convert to using ANSI C-style function definitions.
3320 * Makefile.am: Enable the ansi2knr feature of automake.
3321 * configure.in: ditto.
3323 2002-10-13 Paul D. Smith <psmith@gnu.org>
3325 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3326 for automatic variable values like $^, etc. In the case of very
3327 large lists of prerequisites this causes problems. Instead reuse
3328 a static buffer (resizeable) for each variable.
3330 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3331 target-specific variable definitions. Check for it and set an
3333 (record_target_var): Set the export field to v_export if the
3334 "exported" flag is set.
3335 * doc/make.texi (Target-specific): Document the ability to use
3338 * doc/make.texi: Change the name of the section on automatic
3339 variables from "Automatic" to "Automatic Variables". Added text
3340 clarifying the scope of automatic variables.
3342 2002-10-04 Paul D. Smith <psmith@gnu.org>
3344 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3346 (record_files): Ditto.
3348 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3349 the search for the '=' to only within the enclosing parens.
3351 2002-10-03 Paul D. Smith <psmith@gnu.org>
3353 Version 3.80 released.
3355 * dir.c: Change hash functions to use K&R function definition style.
3356 * function.c: Ditto.
3358 * variable.c: Ditto.
3360 Update to automake 1.7.
3362 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3363 (pdf): Remove this target as automake now provides one.
3365 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3367 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3369 * makefile.com: Updates for GNU make 3.80.
3370 * makefile.vms: Ditto.
3372 2002-09-23 Paul D. Smith <psmith@gnu.org>
3374 * read.c (enum make_word_type): Remove w_comment.
3375 (get_next_mword): Don't treat comment characters as special; where
3376 this function is used we will never see a comment (it's stripped
3377 before we get here) and treating comments specially means that
3378 targets like "foo\#bar" aren't handled properly.
3380 2002-09-18 Paul D. Smith <psmith@gnu.org>
3382 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3384 * read.c (eval): Expansion of arguments to export/unexport was
3385 ignoring all arguments after the first one. Change the algorithm
3386 to expand the whole line once, then parse the results.
3388 2002-09-17 Paul D. Smith <psmith@gnu.org>
3390 Fix Bug #940 (plus another bug I found while looking at this):
3392 * read.c (record_target_var): enter_file() will add a new entry if
3393 it's a double-colon target: we don't want to do that in this
3394 situation. Invoke lookup_file() and only enter_file() if it does
3395 not already exist. If the file we get back is a double-colon then
3396 add this variable to the "root" double-colon target.
3398 * variable.c (initialize_file_variables): If this file is a
3399 double-colon target but is not the "root" target, then initialize
3400 the root and make the root's variable list the parent of our
3403 2002-09-13 Paul D. Smith <psmith@gnu.org>
3405 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3407 * hash.c (round_up_2): Get rid of a warning.
3409 2002-09-12 Paul D. Smith <psmith@gnu.org>
3411 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3412 so it doesn't complain about getloadavg.c.
3414 * commands.c (set_file_variables): Make sure we always alloca() at
3415 least 1 character for the value of $? (for '\0').
3417 2002-09-11 Paul D. Smith <psmith@gnu.org>
3419 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3420 macro to use RESULT instead of the incorrect _RESULT_.
3422 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3423 and atomic_readdir(). We need to #include dirent.h to get this to
3425 * misc.c (atomic_readdir): Fix typos.
3427 2002-09-10 Paul D. Smith <psmith@gnu.org>
3429 * read.c (eval): Expand variable lists given to export and
3430 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3431 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3433 * doc/make.texi (Variables/Recursion): Document this.
3434 (Conditional Syntax): And here.
3436 2002-09-09 Paul D. Smith <psmith@gnu.org>
3438 * configure.in: Check for memmove().
3440 2002-09-07 Paul D. Smith <psmith@gnu.org>
3442 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3443 Michael Sterrett <msterret@coat.com> reports that while it has
3444 SA_RESTART, it does not work properly.
3446 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3447 that invokes stat() and loops to do it again if it returns EINTR.
3448 (atomic_readdir): Ditto, with readdir().
3450 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3451 and readdir() to atomic_stat() and atomic_readdir().
3453 2002-09-04 Paul D. Smith <psmith@gnu.org>
3455 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3456 reports that GNU make sometimes doesn't recognize that targets can
3457 be made, when directories can be created as prerequisites. He
3458 reports that changing the order of predicates in the DEP->changed
3459 flag test so that lookup_file() is always performed, solves this
3462 2002-08-08 Paul D. Smith <psmith@gnu.org>
3464 * configure.in: Require a newer version of gettext.
3466 * misc.c (perror_with_name): Translate the format string (for
3467 right-to-left language support).
3468 (pfatal_with_name): Ditto.
3470 * main.c: Create a static array of strings to store the usage
3471 text. This is done to facilitate translations.
3472 (struct command_switch): Remove argdesc and description fields.
3473 (switches): Remove values for obsolete fields.
3474 (print_usage): Print each element of the usage array.
3476 * hash.c: Change function definitions to be K&R style.
3478 2002-08-02 Paul D. Smith <psmith@gnu.org>
3480 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3481 this one because it's too hard to get right. We'll look at it for
3483 * main.c (main): Don't create the .TARGETS variable.
3484 * variable.c (handle_special_var): Don't handle .TARGETS.
3486 2002-08-01 Paul D. Smith <psmith@gnu.org>
3488 * main.c (switches): Add a new option, -B (--always-make). If
3489 specified, make will rebuild all targets that it encounters even
3490 if they don't appear to be out of date.
3491 (always_make_flag): New flag.
3492 * make.h: Extern always_make_flag.
3493 * remake.c (update_file_1): Check always_make_flag; if it's set we
3494 will always rebuild any target we can, even if none of its
3495 prerequisites are newer.
3498 * doc/make.texi (Shell Function): Make it clear that make
3499 variables marked as "export" are not passed to instances of the
3502 Add new introspection variable .VARIABLES and .TARGETS.
3504 * variable.c (handle_special_var): New function. If the variable
3505 reference passed in is "special" (.VARIABLES or .TARGETS),
3506 calculate the new value if necessary. .VARIABLES is handled here:
3507 walk through the hash of defined variables and construct a value
3508 which is a list of the names. .TARGETS is handled by
3509 build_target_list().
3510 (lookup_variable): Invoke handle_special_var().
3511 * file.c (build_target_list): Walk through the hask of known files
3512 and construct a list of the names of all the ones marked as
3514 * main.c (main): Initialize them to empty (and as simple variables).
3515 * doc/make.texi (Special Variables): Document them.
3516 * NEWS: Mention them.
3518 * variable.h (struct variable): Add a new flag "exportable" which
3519 is true if the variable name is valid for export.
3520 * variable.c (define_variable_in_set): Set "exportable" when a new
3521 variable is defined.
3522 (target_environment): Use the "exportable" flag instead of
3523 re-checking the name here... an efficiency improvement.
3525 2002-07-31 Paul D. Smith <psmith@gnu.org>
3527 * config.h-vms.template: Updates to build on VMS. Thanks to
3528 Brian_Benning@aksteel.com for helping verify the build.
3529 * makefile.com: Build the new hash.c file.
3530 * hash.h: Use strcpmi(), not stricmp(), in the
3531 HAVE_CASE_INSENSITIVE_FS case.
3533 2002-07-30 Paul D. Smith <psmith@gnu.org>
3535 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3536 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3537 Reported by <Brian_Benning@aksteel.com>.
3539 2002-07-10 Paul D. Smith <psmith@gnu.org>
3541 * variable.c (pop_variable_scope): Remove variable made unused by
3542 new hash infrastructure.
3543 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3544 comparisons as well as name comparisons.

3546 * file.c (lookup_file): Remove variables made unused by new hash
3548 * dir.c (directory_contents_hash_2): Missing return of hash value.
3549 (dir_contents_file_exists_p): Remove variables made unused by new
3550 hash infrastructure.
3553 Installed Greg McGary's integration of the hash functions from the
3554 GNU id-utils package:
3556 2002-07-10 Greg McGary <greg@mcgary.org>
3558 * scripts/functions/filter-out: Add literals to to the
3559 pattern space in order to add complexity, and trigger
3560 use of an internal hash table. Fix documentation strings.
3561 * scripts/targets/INTERMEDIATE: Reverse order of files
3562 passed to expected `rm' command.
3564 2002-07-10 Greg McGary <greg@mcgary.org>

3635 (uniquize_deps): Use hash table to efficiently identify duplicates.
3636 (find_char_unquote): Accept two char-constant stop chars, rather
3637 than a string constant, avoiding zillions of calls to strchr.
3638 Tighten inner search loops to test only for desired delimiters.
3640 * variable.c (variable_hash_1, variable_hash_2,
3641 variable_hash_cmp): New functions.
3642 (variable_table): Declare as `struct hash_table'.
3643 (global_variable_set): Remove initialization.
3644 (init_hash_global_variable_set): New function.
3645 (define_variable_in_set): Use new hash table package.
3646 (lookup_variable): Likewise.
3647 (lookup_variable_in_set): Likewise.
3648 (initialize_file_variables): Likewise.
3649 (pop_variable_scope): Likewise.
3650 (create_new_variable_set): Likewise.
3651 (merge_variable_sets): Likewise.
3652 (define_automatic_variables): Likewise.
3653 (target_environment): Likewise.
3654 (print_variable_set): Likewise.
3656 2002-07-10 Paul D. Smith <psmith@gnu.org>
3658 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3659 prerequisite list. A real SysV make will expand the entire
3660 prerequisites list _twice_: we don't do that as it's a big
3661 backward-compatibility problem. We only replace those specific
3664 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3665 references left in the list of prerequisites. Check for .POSIX as
3666 we record targets, so we can disable non-POSIX behavior while
3667 reading makefiles as well as running them.
3668 (eval): Check the prerequisite list to see if we have anything
3669 that looks like a SysV prerequisite variable reference.
3671 2002-07-09 Paul D. Smith <psmith@gnu.org>
3673 * doc/make.texi (Prerequisite Types): Add a new section describing
3674 order-only prerequisites.
3676 * read.c (uniquize_deps): If we have the same file as both a
3677 normal and order-only prereq, get rid of the order-only prereq,
3678 since the normal one supersedes it.
3680 2002-07-08 Paul D. Smith <psmith@gnu.org>
3682 * AUTHORS: Added Greg McGary to the AUTHORS file.
3683 * NEWS: Blurbed order-only prerequisites.
3684 * file.c (print_file): Show order-only deps properly when printing
3687 * maintMakefile: Add "update" targets for wget'ing the latest
3688 versions of various external files. Taken from Makefile.maint in
3691 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3692 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3694 2002-07-07 Paul D. Smith <psmith@gnu.org>
3696 * po/*.po: Remove. We'll use wget to retrieve them at release
3699 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3700 rather than a shell you get an exception. Make sure we look up
3701 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3703 * remake.c (notice_finished_file): Fix handling of -t flag.
3704 Patch provided by Henning Makholm <henning@makholm.net>.
3706 * implicit.c (pattern_search): Some systems apparently run short
3707 of stack space, and using alloca() in this function caused an
3708 overrun. I modified it to use xmalloc() on the two variables
3709 which seemed like they might get large. Fixes Bug #476.
3711 * main.c (print_version): Update copyright notice to conform with
3713 (print_usage): Update help output.
3715 * function.c (func_eval): Create a new make function, $(eval
3716 ...). Expand the arguments, put them into a buffer, then invoke
3717 eval_buffer() on the resulting string.
3718 (func_quote): Create a new function, $(quote VARNAME). Inserts
3719 the value of the variable VARNAME without expanding it any
3722 * read.c (struct ebuffer): Change the linebuffer structure to an
3723 "eval buffer", which can be either a file or a buffer.
3724 (eval_makefile): Move the code in the old read_makefile() which
3725 located a makefile into here: create a struct ebuffer with that
3726 information. Have it invoke the new function eval() with that
3728 (eval_buffer): Create a new function that creates a struct ebuffer
3729 that holds a string buffer instead of a file. Have it invoke
3730 eval() with that ebuffer.
3731 (eval): New function that contains the guts of the old
3732 read_makefile() function: this function parses makefiles. Obtains
3733 data to parse from the provided ebuffer. Some modifications to
3734 make the flow of the function cleaner and clearer. Still could
3735 use some work here...
3736 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3737 contents of the define/endef variable from the ebuffer.
3738 (readstring): Read the next line from a string-style ebuffer.
3739 (readline): Read the next line from an ebuffer. If it's a string
3740 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3743 * dep.h (eval_buffer): Prototype eval_buffer();
3745 * variable.c (do_variable_definition): Make sure that all
3746 non-target-specific variables are registered in the global set.
3747 If we're invoked from an $(eval ...) we might be inside a $(call
3748 ...) or other function which has pushed a variable scope; we still
3749 want to define our variables from evaluated makefile code in the
3752 2002-07-03 Greg McGary <greg@mcgary.org>
3754 * dep.h (struct dep) [ignore_mtime]: New member.
3755 [changed]: convert to a bitfield.
3756 * implicit.c (pattern_search): Zero ignore_mtime.
3757 * main.c (main, handle_non_switch_argument): Likewise.
3758 * rule.c (convert_suffix_rule): Likewise.
3759 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3760 (read_makefile): Parse '|' in prerequisite list.
3761 (uniquize_deps): Consider ignore_mtime when comparing deps.
3762 * remake.c (update_file_1, check_dep): Don't force remake for
3763 dependencies that have d->ignore_mtime.
3764 * commands.c (FILE_LIST_SEPARATOR): New constant.
3765 (set_file_variables): Don't include a
3766 prerequisite in $+, $^ or $? if d->ignore_mtime.
3769 2002-06-18 Paul D. Smith <psmith@gnu.org>
3771 * make.texinfo: Updates for next revision. New date/rev/etc.
3772 Recreate all Info menus. Change license on the manual to the GNU
3773 Free Documentation License. A number of typos.
3774 (Variables Simplify): Don't use "-" before it's defined.
3775 (Automatic Prerequisites): Rewrite the target example to work
3776 properly if the compile fails. Remove incorrect comments about
3777 how "set -e" behaves.
3778 (Text Functions): Move the "word", "wordlist", "words", and
3779 "firstword" functions here, from "File Name Functions".
3780 * make-stds.texi: Update from latest GNU version.
3781 * fdl.texi: (created) Import the latest GNU version.
3783 2002-06-06 Paul D. Smith <psmith@gnu.org>
3785 * variable.c (do_variable_definition): New function: extract the
3786 part of try_variable_definition() that actually sets the value
3787 into a separate function.
3788 (try_variable_definition): Call do_variable_definition() after
3789 parsing the variable definition string.
3790 (define_variable_in_set): Make the name argument const.
3792 * variable.h (enum variable_flavor): Make public.
3793 (do_variable_definition): Create prototype.
3795 * read.c (read_all_makefiles): Create a new built-in variable,
3797 (read_makefile): Add each makefile read in to this variable value.
3799 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3801 * Makefile.DOS.template: Tweak according to changes in the
3802 distribution. Add back the dependencies of *.o files.
3804 * configh.dos.template: Synchronize with config.h.in.
3806 2002-05-09 Paul D. Smith <psmith@gnu.org>
3808 * file.c (file_timestamp_now): Use K&R function declaration.
3810 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3811 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3812 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3813 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3814 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3815 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3816 nlist.n_name is a pointer rather than an array.
3818 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3819 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3820 * configure.in: Use it instead of the old version.
3822 * main.c (main): Prefer setvbuf() to setlinebuf().
3824 2002-05-08 Paul D. Smith <psmith@gnu.org>
3826 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3827 (loadavg_LDADD): Ditto.
3829 2002-04-29 Paul D. Smith <psmith@gnu.org>
3831 * expand.c (recursively_expand_for_file): Rename
3832 recursively_expand() to recursively_expand_for_file() and provide
3833 an extra argument, struct file. If the argument is provided, set
3834 the variable scope to that of the file before expanding.
3835 * variable.h (recursively_expand): Make this a macro that invokes
3836 recursively_expand_for_file() with a NULL file pointer.
3837 * variable.c (target_environment): Call the renamed function and
3838 provide the current file context.
3839 Fixes Debian bug #144306.
3841 2002-04-28 Paul D. Smith <psmith@gnu.org>
3843 Allow $(call ...) user-defined variables to be self-referencing
3844 without throwing an error. Allows implementation of transitive
3845 closures, among other possibly useful things.
3846 Requested by: Philip Guenther <guenther@sendmail.com>
3848 * variable.h (struct variable): Add a new field: exp_count, and
3849 new macros to hold its size and maximum value.
3850 (warn_undefined): Make this a macro.
3851 * variable.c (define_variable_in_set): Initialize it.
3852 * expand.c (recursively_expand): If we detect recursive expansion
3853 of a variable, check the exp_count field. If it's greater than 0
3854 allow the recursion and decrement the count.
3855 (warn_undefined): Remove this (now a macro in variable.h).
3856 * function.c (func_call): Before we expand the user-defined
3857 function, modify its exp_count field to contain the maximum
3858 number of recursive calls we'll allow. After the call, reset it
3861 2002-04-21 Paul D. Smith <psmith@gnu.org>
3863 Modified to use latest autoconf (2.53), automake (1.6.1), and
3864 gettext (0.11.1). We're using gettext's new "external" support,
3865 to avoid including libintl source with GNU make.
3867 * README.cvs: New file. Explain how to build GNU make from CVS.
3869 * configure.in: Modify checking for the system glob library.
3870 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3871 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3872 etc. will manage it correctly). Set an automake conditional
3873 USE_LOCAL_GLOB to decide whether to compile the glob library.
3875 * getloadavg.c (main): Include make.h in the "TEST" program to
3878 * Makefile.am: Remove special rules for loadavg. Replace them
3879 with Automake capabilities for building extra programs.
3881 * signame.c: This file does nothing if the system provide
3882 strsignal(). If not, it implements strsignal(). If the system
3883 doesn't define sys_siglist, then we make our own; otherwise we use
3885 * signame.h: Removed.
3887 * main.c (main): No need to invoke signame_init(). Update copyright.
3889 * ABOUT-NLS: Removed.
3890 * gettext.c: Removed.
3891 * gettext.h: Get a simplified copy from the gettext package.
3893 * i18n/*.po: Moved to po/.
3896 * config/*: Created. Contains package configuration helper files.
3897 * config.guess, config.sub: Moved to config directory.
3899 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3900 Rework to use new-style autoconf features. Use the "external"
3901 mode for gettext. Make the build.sh config file conditional on
3902 whether build.sh.in exists, to avoid autoconf errors.
3903 * acinclude.m4: Removed almost all macros as being obsolete.
3904 Rewrote remaining macros to use AC_DEFINE.
3905 * acconfig.h: Removed.
3907 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3908 conditional to handle customs support. Remove special handling
3911 2002-04-20 Paul D. Smith <psmith@gnu.org>
3913 * function.c (func_call): Don't mark the argument variables $1,
3914 etc. as recursive. They've already been fully expanded so
3915 there's no need to do it again, and doing so strips escaped $'s.
3916 Reported by Sebastian Glita <glseba@yahoo.com>.
3918 * remake.c (notice_finished_file): Walk through double-colon
3919 entries via the prev field, not the next field!
3920 Reported by Greg McGary <greg@mcgary.org>.
3922 * main.c (main): If the user specifies -q and asks for a specific
3923 target which is a makefile, we got an assert. In that case it
3924 turns out we should continue normally instead.
3926 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3928 * i18n/he.po: Installed a new translation.
3930 2002-01-07 Paul D. Smith <psmith@gnu.org>
3932 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3934 2001-12-04 Paul D. Smith <psmith@gnu.org>
3936 * i18n/ja.po: Installed an updated translation.
3938 2001-09-06 Paul Eggert <eggert@twinsun.com>
3940 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3941 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3943 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3945 (main): Get rid of any avoidable limit on stack size.
3947 2001-09-04 Paul D. Smith <psmith@gnu.org>
3949 * i18n/da.po: Installed an updated translation.
3951 2001-08-03 Paul D. Smith <psmith@gnu.org>
3953 * i18n/fr.po: Installed an updated translation.
3954 Resolves Debian bug #106720.
3956 2001-06-13 Paul D. Smith <psmith@gnu.org>
3958 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3961 2001-06-11 Paul D. Smith <psmith@gnu.org>
3963 * i18n/ko.po: Installed a new translation.
3965 2001-05-06 Paul D. Smith <psmith@gnu.org>
3967 Modify the EINTR handling.
3969 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3970 the way in which we manage the file descriptor/signal handler race
3971 trap to be more efficient.
3973 2001-05-06 Paul Eggert <eggert@twinsun.com>
3975 Restart almost all system calls that are interrupted, instead
3976 of worrying about EINTR. The lone exception is the read() for
3979 * configure.in (HAVE_SA_RESTART): New macro.
3980 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3981 * main.c (main): Use SA_RESTART instead of the old,
3982 nonstandard SA_INTERRUPT.
3984 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3985 * main.c (bsd_signal): New function or macro,
3986 if the implementation doesn't supply it.
3987 (The bsd_signal function will be in POSIX 1003.1-200x.)
3988 (HANDLESIG): Remove.
3989 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3991 * make.h (EINTR_SET): Remove.
3992 (SA_RESTART): New macro.
3994 * arscan.c (ar_member_touch): Don't worry about EINTR.
3995 * function.c (func_shell): Likewise.
3996 * job.c (reap_children, free_child, new_job): Likewise.
3997 * main.c (main): Likewise.
3998 * remake.c (touch_file, name_mtime): Likewise.
4000 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4001 if fstat failed with errno!=EINTR, the error was ignored.
4003 * job.c (set_child_handler_action_flags): New function.
4004 (new_job): Use it to temporarily clear the SIGCHLD action flags
4005 while reading the token.
4007 2001-05-02 Paul D. Smith <psmith@gnu.org>
4009 * job.c (start_job_command): Don't add define/endef per-line flags
4010 to the top-level flags setting.
4012 2001-04-03 Paul D. Smith <psmith@gnu.org>
4014 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4015 bit on error, so check for odd return values, not non-0 return
4017 (VMS_get_member_info): Calculate the timezone differences correctly.
4018 Reported by John Fowler <jfowler@nyx.net>.
4021 2001-03-14 Paul D. Smith <psmith@gnu.org>
4023 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4024 value before invoking define_variable().
4025 Reported by John Fowler <jfowler@nyx.net>.
4027 2001-02-07 Paul D. Smith <psmith@gnu.org>
4029 * read.c (record_target_var): If we reset the variable due to a
4030 command-line variable setting overriding it, turn off the "append"
4033 2001-01-17 Paul D. Smith <psmith@gnu.org>
4035 * variable.c (lookup_variable) [VMS]: When getting values from the
4036 environment, allocate enough space for the _value_ plus escapes,
4037 not enough space for the name plus escapes :-/.
4038 Reported by John Fowler <jfowler@nyx.net>.
4040 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4041 warnings that make generates, so it doesn't look like an error.
4042 Reported by Karl Berry <karl@gnu.org>.
4045 Fix for PR/2020: Rework appended target-specific variables. I'm
4046 fairly confident this algorithm is finally correct.
4048 * expand.c (allocated_variable_append): Rewrite. Instead of
4049 expanding each appended variable then adding all the expanded
4050 strings together, we append all the unexpanded values going up
4051 through the variable set contexts, then expand the final result.
4052 This behaves just like non-target-specific appended variable
4053 values, while the old way didn't in various corner cases.
4054 (variable_append): New function: recursively append the unexpanded
4055 value of a variable, walking from the outermost variable scope to
4057 * variable.c (lookup_variable): Remove the code that looked up the
4058 variable set list if the found variable was "append". We don't
4060 (lookup_variable_in_set): Make this non-static so we can use it
4062 (try_variable_definition): Use lookup_variable_in_set() rather
4063 than faking out current_variable_set_list by hand (cleanup).
4064 * variable.h: Add a prototype for the now non-static
4065 lookup_variable_in_set().
4067 2000-11-17 Paul D. Smith <psmith@gnu.org>
4069 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4070 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4071 before throwing a fit.
4073 2000-11-17 Paul D. Smith <psmith@gnu.org>
4075 * read.c (readline): CRLF calculations had a hole, if you hit the
4076 buffer grow scenario just right. Reworked the algorithm to avoid
4077 the need for len or lastlen at all. Problem description with
4078 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4080 2000-10-24 Paul D. Smith <psmith@gnu.org>
4082 * gettext.c (SWAP): Declare this with the prototype, otherwise
4083 some systems don't work (non-32-bit? Reported for Cray T3E).
4084 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4086 2000-10-05 Paul D. Smith <psmith@gnu.org>
4088 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4089 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4091 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4093 2000-09-22 Paul D. Smith <psmith@gnu.org>
4095 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4096 parts of the real gettext.h here, and we expect to really include
4097 the real gettext.h later. If we keep this #define, it's ignored.
4099 2000-09-21 Paul D. Smith <psmith@gnu.org>
4101 * main.c (log_working_directory): Rework the text to use complete
4102 sentences, to make life simpler for the translators.
4104 2000-08-29 Paul D. Smith <psmith@gnu.org>
4106 * file.c (remove_intermediates): Print a debug message before we
4107 remove intermediate files, so the user (if she uses -d) knows
4110 2000-08-21 Paul D. Smith <psmith@gnu.org>
4112 * variable.c (try_variable_definition): Change how we handle
4113 target-specific append variable defns: instead of just setting the
4114 value, expand it as an append _but_ only within the current
4115 target's context. Otherwise we lose all but the last value if the
4116 variable is appended more than once within the current target
4117 context. Fixes PR/1831.
4119 2000-08-16 Paul D. Smith <psmith@gnu.org>
4121 * function.c (func_shell): Nul-terminate the buffer before
4122 printing an exec error message (just in case it's not!).
4123 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4125 2000-07-25 Paul D. Smith <psmith@gnu.org>
4127 * job.c (construct_command_argv_internal): Add "~" to the list of
4128 sh_chars[] which disallow optimizing out the shell call.
4130 2000-07-23 Paul Eggert <eggert@twinsun.com>
4132 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4133 supersedes --disable-nsec-timestamps.
4134 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4135 * README: Remove --disable-nsec-timestamps.
4137 * filedef.h (struct file.low_resolution_time): New member.
4138 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4139 * remake.c (update_file_1):
4140 Avoid spurious rebuilds due to low resolution time stamps,
4141 generalizing the earlier code that applied only to archive members.
4142 (f_mtime): Archive members always have low resolution time stamps.
4144 * configure.in: Remove --disable-nsec-timestamps, as this has
4145 been superseded by .LOW_RESOLUTION_TIME.
4147 2000-07-23 Paul Eggert <eggert@twinsun.com>
4149 * configure.in (enable_nsec_timestamps): Renamed from
4150 make_cv_nsec_timestamps, since enable/disable options
4151 shouldn't be cached.

4156 * file.c (file_timestamp_now):
4157 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4158 so that clock_gettime is not linked unless needed.
4160 * filedef.h (FILE_TIMESTAMP_HI_RES):
4161 Remove definition; "configure" now does this.
4163 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4164 to before high resolution file timestamp check,
4165 since that check now uses uintmax_t.
4166 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4167 high resolution file timestamps.
4168 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4169 so that we don't link in clock_gettime unnecessarily.
4171 2000-07-17 Paul D. Smith <psmith@gnu.org>
4173 * i18n/ja.po: New version of the translation file.
4175 2000-07-07 Paul D. Smith <psmith@gnu.org>
4177 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4178 the offset calculation.
4179 (name_mtime): Replace EINTR test with EINTR_SET macro.
4181 2000-07-07 Paul Eggert <eggert@twinsun.com>
4185 * remake.c (update_file_1):
4186 Avoid spurious rebuilds of archive members due to their
4187 timestamp resolution being only one second.
4188 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4189 the clock's resolution being lower than file timestamps'.
4190 When warning about future timestamps, report only the discrepancy,
4191 not the absolute value of the timestamp and the current time.
4193 * file.c (file_timestamp_now): New arg RESOLUTION.
4194 * filedef.h (file_timestamp_now): Likewise.
4195 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4197 2000-07-05 Paul D. Smith <psmith@gnu.org>
4199 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4200 to listp. Fixes PR/1793.
4202 2000-06-26 Paul Eggert <eggert@twinsun.com>
4204 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4206 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4208 * remake.c (f_mtime): Remove unused var memtime.
4210 2000-06-25 Martin Buchholz <martin@xemacs.org>
4212 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4213 Ran spell-check on make.texinfo.
4215 2000-06-23 Paul D. Smith <psmith@gnu.org>
4217 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4218 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4219 * make.h: Define these macros.
4221 * Version 3.79.1 released.
4223 * configure.in: Add a new option, --disable-nsec-timestamps, to
4224 avoid using sub-second timestamps on systems that support it. It
4225 can lead to problems, e.g. if your makefile relies on "cp -p".
4226 * README.template: Document the issue with "cp -p".
4228 * config.guess, config.sub: Updated.
