526 -*-eval-flags-*- (necessary to allow recursion to work properly).
527 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
529 * NEWS: Describe the new --eval command line argument.
530 * doc/make.texi (Options Summary): Document --eval.
532 * dep.h: eval_buffer() returns void.
533 * read.c (eval_buffer): Ditto.
536 * variable.h (define_variable_cname): New macro for constant
538 * default.c (set_default_suffixes): Use it.
539 * main.c (main): Ditto.
540 (handle_non_switch_argument): Ditto.
541 (define_makeflags): Ditto.
542 * read.c (read_all_makefiles): Ditto.
543 * variable.c (define_automatic_variables): Ditto.
545 * commands.c (dep_hash_cmp): Avoid casts.
549 2009-10-22 Boris Kolpackov <boris@codesynthesis.com>
551 * read.c (read_all_makefiles): Mark the default makefile dependency
554 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
556 * read.c (do_undefine): Free the expanded variable name.
558 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
559 to normal upgrade logic from dep_hash_cmp to set_file_variables.
561 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
563 * dep.h (uniquize_deps): Remove.
565 * read.c (uniquize_deps): Merge into set_file_variables in
567 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
569 * commands.c (set_file_variables): Avoid modifying the dep
570 chain to achieve uniqueness. Fixes savannah bug 25780.
572 * implicit.c (pattern_search): Instead of re-setting all automatic
573 variables for each rule we try, just update $*.
575 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
577 * variable.h (undefine_variable_in_set): New function declaration.
578 (undefine_variable_global): New macro.
580 * variable.c (undefine_variable_in_set): New function implementation.
582 * read.c (vmodifiers): Add undefine_v modifier.
583 (parse_var_assignment): Parse undefine.
584 (do_undefine): Handle the undefine directive.
585 (eval): Call do_undefine if undefine_v is set.
587 * main.c (.FEATURES): Add a keyword to indicate the new feature.
589 * doc/make.texi (Undefine Directive): Describe the new directive.
591 * NEWS: Add a note about the new directive.
593 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
595 * implicit.c (pattern_search): Initialize file variables only
596 if we need to parse a rule that requires the second expansion.
598 2009-10-03 Paul Smith <psmith@gnu.org>
600 * make.h: Include <alloca.h> even on systems where __GNUC__ is
601 defined. Not sure why it was done the other way.
602 Requested by David Boyce <dsb@boyski.com>.
604 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
606 * dep.h (dep): Add the DONTCARE bitfield.
608 * filedef.h (file):Add the NO_DIAG bitfield.
610 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
611 not struct file (a file can be a dependency of many targets,
612 some don't care, some do).
614 * remake.c (update_goal_chain): Propagate DONTCARE from struct
615 dep to struct file before updating the goal and restore it
617 (update_file): Don't prune the dependency graph if this target
618 has failed but the diagnostics hasn't been issued.
619 (complain): Scan the file's dependency graph to find the file
620 that caused the failure.
621 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
622 whether to print diagnostics.
624 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
626 2009-09-28 Paul Smith <psmith@gnu.org>
628 * doc/make.texi (Pattern Intro): Move the match algorithm
629 discussion into the "Pattern Match" node.
630 (Pattern Match): Expand on the pattern rule matching algorithm.
632 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
634 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
635 much of the command line on a single pass.
637 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
639 * varible.c (create_pattern_var): Insert variables into the
640 PATTERN_VARS list in the shortest patterns first order.
642 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
643 used to sort the rules.
644 (stemlen_compare): Compare two tryrule elements.
645 (pattern_search): Sort the rules so that they are in the shortest
648 * main.c (.FEATURES): Add a keyword to indicate the new behavior.

651 new pattern-specific variables application order.
652 (Introduction to Pattern Rules): Describe the new pattern rules
655 * NEWS: Add a note about the new behavior.
657 2009-09-27 Paul Smith <psmith@gnu.org>
659 * doc/make.texi (Double-Colon): Mention that pattern rules with
660 double-colons have a different meaning. Savannah bug #27497.
662 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
664 * configh.dos.template: Remove unconditional definition of
665 SYS_SIGLIST_DECLARED.
666 Include <sys/version.h> because ports of GCC 4.3.0 and later no
667 longer include it, so macros like __DJGPP_MINOR__ are no longer
668 defined automatically.
670 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
671 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
672 instead of using the hardcoded ones.
673 (SUBDIRS): doc subdir added.
674 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
675 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
676 create html formated docs. texi2html may not be ported to DOS.
677 (make.info, make.dvi, make.ps, make.html): Make targets depend on
679 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
680 -I switch to look in ./ instead of ./doc.
681 (html): Target depend on html-recursive instead of make_1.html.
682 (make_1.html): Removed.
683 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
684 (all-recursive): Allow for more than one subdir in the build
686 (mostlyclean-recursive, clean-recursive, distclean-recursive)
687 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
688 (tags-recursive): Allow for more than one subdir in the build
690 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
691 targets. Enter into doc/ to produce the targets.
692 (all-am): $(INFO_DEPS) replaced by info.
694 2009-09-26 Paul Smith <psmith@gnu.org>
696 * read.c (record_files): Use free_ns() to free struct nameseq.
699 * rule.c (freerule): Use free_dep_chain().
701 * read.c (record_files): Free FILENAMES chain for implicit rules.
702 (eval): Static pattern targets go into the string cache.
704 * function.c (string_glob): Free NAME in the nameseq chain.
706 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
708 * implicit.c (pattern_search): Terminate early if we haven't
709 found any rules to try (performance improvement).
711 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
713 * implicit.c (pattern_search): Merge three parallel arrays,
714 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
715 of struct TRYRULE. In the old version the latter two arrays
716 had insufficient length.
718 2009-09-24 Paul Smith <psmith@gnu.org>
720 * implicit.c (pattern_search): Add back support for order-only
721 prerequisites for secondary expansion implicit rules, that were
722 accidentally dropped. If we find a "|", enable order-only mode
723 and set IGNORE_MTIME on all deps that are seen afterward.
724 (pattern_search): Fix memory leaks: for intermediate files where
725 we've already set the file variable and pattern variable sets, be
726 sure to either save or free them as appropriate.
728 2009-09-23 Paul Smith <psmith@gnu.org>
730 Rework the way secondary expansion is stored, for efficiency.
731 This changes secondary expansion so that ONLY WHEN we know we have
732 a possibility of needing secondary expansion, do we defer the
733 secondary expansion. This means more parsing the deps but we use
734 a lot less memory (due to the strcache). Also, this fixes
737 * read.c (eval): Don't parse the dep string here anymore.
738 (record_files): Take the dep argument as an unparsed string. If
739 secondary expansion is enabled AND the prereq string has a '$' in
740 it, then set NEED_2ND_EXPANSION and keep the entire string.
741 Otherwise, parse the dep string here to construct the dep list
742 with the names in the strcache.
744 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
745 duplicate the name string (others are in the strcache).
747 * implicit.c: Remove struct idep and free_idep_chain(): unused.
748 (struct patdeps): New structure to store prereq information.
749 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
750 which prerequisites need expansion, and expand only those.
752 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
753 and enter_prereqs(). split_prereqs() takes a fully-expanded string
754 and splits it into a DEP list, handling order-only prereqs.
755 (enter_prereqs): This function enters a list of DEPs into the file
756 database. If there's a stem defined, expand any pattern chars.
757 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
758 set. Use the above functions.
759 (snap_deps): Only perform second expansion on prereqs that need it,
760 as defined by the NEED_2ND_EXPANSION flag.
761 (print_prereqs): New function to print the prereqs
762 (print_file): Call print_prereqs() rather than print inline.
764 * hash.h (STRING_COMPARE): Take advantage of strcache() by
766 (STRING_N_COMPARE): Ditto.
767 (ISTRING_COMPARE): Ditto.
769 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
770 (parse_file_seq): Return void*
771 * read.c (parse_file_seq): Return void*.
772 (eval): Invoke macroized version of parse_file_seq()
773 * default.c (set_default_suffixes): Ditto.
774 * file.c (split_prereqs): Ditto.
775 * function.c (string_glob): Ditto.
776 * main.c (main): Ditto.
777 * rule.c (install_pattern_rule): Ditto.
779 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
781 2009-09-16 Paul Smith <psmith@gnu.org>
783 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
785 * dep.h: Create alloc_dep() / free_dep() macros.
787 * implicit.c (pattern_search): Take advantage of the new
788 parse_file_seq() to add the directory prefix to each prereq.
790 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
791 all. Avoid reversing chains. Support adding prefixes.
792 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
793 cached/non-cached results.
794 (eval): Remove multi_glob() & invoke new parse_file_seq().
795 * rule.c (install_pattern_rule): Ditto.
796 * main.c (main): Ditto.
797 * implicit.c (pattern_search): Ditto.
798 * function.c (string_glob): Ditto.
799 * file.c (parse_prereqs): Ditto.
800 * default.c (set_default_suffixes): Ditto.
802 * variable.c (parse_variable_definition): Don't run off the end of
803 the string if it ends in whitespace (found with valgrind).
805 * commands.c (set_file_variables): Keep space for all targets in
806 $? if -B is given (found with valgrind).
808 2009-09-15 Paul Smith <psmith@gnu.org>
810 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
811 (xcalloc): Add new function.
812 * make.h: New declarations.
814 * ar.c (ar_glob_match): New calling method for concat().
815 * main.c (main): Ditto.
816 (decode_env_switches): Ditto.
817 * read.c (eval_makefile): Ditto.
818 (tilde_expand): Ditto.
819 (parse_file_seq): Ditto.
820 * variable.c (target_environment): Ditto.
821 (sync_Path_environment): Ditto.
823 * ar.c (ar_glob_match): Use xcalloc().
824 * dir.c (file_impossible): Ditto.
825 * file.c (enter_file): Ditto.
826 * job.c (new_job): Ditto.
827 * read.c (parse_file_seq): Ditto.
828 * vmsfunctions.c (opendir): Ditto.
830 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
832 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
833 inside the loop that looks up environment for PATH.
835 2009-08-31 Eli Zaretskii <eliz@gnu.org>
837 * function.c (windows32_openpipe): Update envp after calling
838 sync_Path_environment.
840 2009-08-02 Paul Smith <psmith@gnu.org>
842 * remake.c (notice_finished_file): Ensure file->cmds is not null
843 before looping through them. Fixes Savannah bug #21824.
845 * doc/make.texi (Wildcard Examples): Clarify when objects is
846 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
847 (Include): Clarify the behavior of -include.
848 Fixes Savannah bug #18963.
850 2009-08-01 Paul Smith <psmith@gnu.org>
852 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
853 etc. come on the command line. Fixes Savannah bug #27093.
855 * expand.c (expand_argument): If the argument is large enough use
856 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
858 * variable.c (do_variable_definition): Avoid using alloca() to
859 hold values, which can be large. Fixes Savannah bug #23960.
861 * job.c (new_job): Use memmove() instead of strcpy() since both
862 pointers are in the same memory block. Fixes Savannah bug #27148.
863 Patch by Petr Machata.
865 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
867 * job.c (construct_command_argv_internal): Add "ulimit" and
868 "unset" to the sh_cmds for Unixy shells.
870 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
872 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
873 that set make_cv_sys_gnu_glob, so they are also correctly set
874 when the cache has been populated before.
876 2009-07-04 Eli Zaretskii <eliz@gnu.org>
878 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
879 exist, as realpath(3) does where it's supported.
881 2006-07-04 Eli Zaretskii <eliz@gnu.org>
883 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
884 (abspath): Support systems that define HAVE_DOS_PATHS (have
885 drive letters in their file names). Use IS_PATHSEP instead of a
886 literal '/' comparison. Fixes Savannah bug #26886.
888 2009-06-14 Paul Smith <psmith@gnu.org>
890 * remake.c (update_file_1): Remember the original file we marked
891 as updating, so we can clear that flag again. If we find a target
892 via vpath, FILE might change.
893 (check_dep): Ditto. Fixes Savannah bug #13529.
894 Patch by Reid Madsen <reid.madsen@tek.com>.
896 2009-06-13 Paul Smith <psmith@gnu.org>
898 * doc/make.texi (MAKEFILES Variable): Be explicit that files
899 included by MAKEFILES cannot give default goals.
900 * read.c (eval): If set_default is not set, pass the no-default-goal
901 value when we read included makefiles. Fixes Savannah bug #13401.
903 * ar.c (ar_name): Ensure that targets with empty parens aren't
904 considered archive member references: archive members must have a
905 non-empty "member" string. Fixes Savannah bug #18435.
907 * function.c (string_glob): Rely on multi_glob() to determine
908 whether files exist or not. Remove call to file_exists_p() which
909 is not always correct. Fixes Savannah bug #21231.
910 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
911 then only files that really exist will be returned.
912 * dep.h: Add new argument to multi_glob().
913 * rule.c (install_pattern_rule): Ditto.
914 * read.c (eval): Ditto.
915 * main.c (main): Ditto.
916 * implicit.c (pattern_search): Ditto.
917 * file.c (parse_prereqs): Ditto.
918 * default.c (set_default_suffixes): Ditto.
920 2009-06-09 Paul Smith <psmith@gnu.org>
922 * commands.c (set_file_variables): If always_make_flag is set,
923 always add the prereq to $?. Fixes Savannah bug #17825.
925 * remake.c (update_file_1): When rebuilding deps of FILE, also try
926 to rebuild the deps of all the also_make targets for that file.
927 Fixes Savannah bug #19108.
929 * implicit.c (pattern_search): Undo test for is_target, added by
930 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
931 Rule Search Algorithm". Fixes Savannah bug #17752.
933 * main.c (clean_jobserver): Clear the jobserver_fds options and
934 set job_slots to the default when we clean up.
935 (define_makeflags): Return the new MAKEFLAGS value.
936 (main): Reset MAKEFLAGS in the environment when we re-exec.
937 Fixes Savannah bug #18124.
939 2009-06-08 Paul Smith <psmith@gnu.org>
941 * read.c (eval): Collapse continuations post-semicolon on target-
942 specific variables. Fixes Savannah bug #17521.
944 2009-06-07 Paul Smith <psmith@gnu.org>
946 * job.c (reap_children): For older systems without waitpid() (are
947 there any of these left?) run wait(2) inside EINTRLOOP to handle
948 EINTR errors. Fixes Savannah bug #16401.
950 * (various): Debug message cleanup. Fixes Savannah bug #16469.
952 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
954 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
955 not the end, to catch second expansion $(eval ...) defining new
956 target/prereq relationships during snap_deps.
957 Fixes Savannah bug #24622.
959 * read.c (record_files): The second-expansion "f->updating" hack
960 was not completely correct: if assumed that the target with
961 commands always had prerequisites; if one didn't then the ordering
962 was messed up. Fixed for now to use f->updating to decide whether
963 to preserve the last element in the deps list... but this whole
964 area of constructing and reversing the deps list is too confusing
965 and needs to be reworked. Fixes Savannah bug #21198.
967 2009-06-06 Paul Smith <psmith@gnu.org>
969 * hash.c (hash_insert): Remove useless test for NULL.
970 Fixes Savannah bug #21823.
972 * make.h: Move SET_STACK_SIZE determination to make.h.
973 * main.c (main): New global variable, STACK_LIMIT, holds the
974 original stack limit when make was started.
975 * job.c (start_job_command): Reset the stack limit, if we changed it.
976 Fixes Savannah bug #22010.
978 * remake.c (check_dep): Only set the target's state to not-started
979 if it's not already running. Found this while testing -j10 builds
980 of glibc: various targets were being rebuilt multiple times.
981 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
984 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
985 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
988 2009-06-04 Paul Smith <psmith@gnu.org>
990 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
992 * maintMakefile: Modify access of config and gnulib Savannah
993 modules to use GIT instead of CVS.
995 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
996 Fixes Savannah bug #24655.
998 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
999 this can happen during some invocations of $(eval ...) for example.
1000 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1002 2009-06-02 Paul Smith <psmith@gnu.org>
1004 * configure.in: Check for fileno()
1005 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1006 for the makefile file so invocations of $(shell ...) don't inherit it.
1007 Fixes Savannah bug #24277.
1009 2009-06-01 Paul Smith <psmith@gnu.org>
1011 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1012 expansion was handled incorrectly. Rework the default goal
1013 handling to save the variable only. Remove default_goal_file and
1015 * read.c (eval): Check default_goal_var, not default_goal_name.
1016 * read.c (record_target_var): Don't check default_goal_file here.
1018 2009-05-31 Paul Smith <psmith@gnu.org>
1020 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1021 it, and if the multi_glob() returns nothing (say it expanded to
1022 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1024 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1025 $(and ..) to the reference. Fixes Savannah bug #25694.
1027 * make.1: Be clear that some recipes will be executed even with -n.
1028 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1030 * doc/make.texi (Override Directive): Make more clear how
1031 overrides and appends interact.
1032 Elucidates part of Savannah bug #26207.
1034 * read.c (record_target_var): Don't reset the origin on
1035 target-specific variables; try_variable_definition() will handle
1036 this correctly. Fixes Savannah bug #26207.
1038 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1039 Fixes Savannah bug #25712.
1041 * implicit.c (pattern_search): Keep a pointer to the beginning of
1042 the filename and save that instead of the constructed pointer.
1043 Fixes Savannah bug #26593.
1044 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1046 2009-05-30 Paul Smith <psmith@gnu.org>
1048 * doc/make.texi (Multi-Line): Add a description of the new abilities
1049 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1050 "command sequence" vs. "recipe" syntax.
1051 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1052 after a define, to create variables with those flavors.
1054 2009-05-25 Paul Smith <psmith@gnu.org>
1056 Reworked the parser for variable assignments to allow multiple
1057 modifiers, and in any order. Also allows variable and
1058 prerequisites to be modifier names ('export', 'private', etc.)
1060 * NEWS: Add notes about user-visible changes.
1062 * read.c (struct vmodifiers): Remember what modifiers were seen.
1063 (parse_var_assignment): New function to parse variable assignments.

1097 -t with phony targets.
1099 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>

1187 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1188 HAVE_DECL_SYS_SIGLIST.
1190 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1191 build does not use child_execute_job.
1193 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1194 export the SHELL environment variable to the child.
1196 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1215 * remake.c (f_mtime): Print time difference values between 100 and

1218 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1220 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1221 a more complex value than a simple shell: if it's not a default
1222 shell now then expand it and see if is a default shell then.
1224 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1226 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1227 pathnames, with const strings.
1228 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1250 * doc/make.texi (Special Variables): Moved this into the "How to
1251 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1255 (Simple Makefile): Ditto.
1256 (Rule Syntax): Ditto.
1257 (Command Syntax): Ditto.
1258 (Error Messages): Ditto.
1260 2007-09-10 Paul Smith <psmith@gnu.org>
1262 * commands.c (print_commands): Don't print an extra line in the
1263 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1265 * read.c (construct_include_path): Add the full string to the cache; we
1266 were chopping the last char.
1268 * NEWS: Announce the .RECIPEPREFIX special variable.
1269 * variable.c (lookup_special_var): Rename from handle_special_var().
1270 (lookup_variable): Call the new name.

1275 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1276 * main.c (main): Create the .RECIPEPREFIX special variable.
1277 * read.c (eval): Remove the cmd_prefix characters from the command
1278 scripts here, so they're not stored in the commands array at all,
1279 rather than waiting and stripping them out during command construction.
1280 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1282 2007-08-15 Paul Smith <psmith@gnu.org>
1284 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1285 file has had the section info removed, so add some to make.texi
1286 before we include it.
1288 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1290 * remake.c (check_dep): Reset the target state for intermediate

1306 2007-07-13 Paul Smith <psmith@gnu.org>
1308 * file.c (expand_deps): Use variable_buffer as the start of the
1309 buffer, not the original pointer (in case it was reallocated).
1310 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1311 Fixes Savannah bug #20452.
1313 2007-07-04 Paul Smith <psmith@gnu.org>

1336 * job.c (new_job): Add debug info to specify where make found the
1337 command script it is running to build a target.
1338 Fixes Savannah bug #18617.

1348 Dave Korn <dave.korn@artimi.com>
1350 2007-05-08 Paul Smith <psmith@gnu.org>
1352 Fix Savannah bug #19656:
1354 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1356 * make.h: Change all case-insensitive string compares to use
1357 strcasecmp() (from POSIX). If we don't have that but do have one
1358 of the others, define strcasecmp to be one of those instead. If
1359 we don't have any, declare a prototype for our own version.
1361 * misc.c (strcasecmp): Use this if we can't find any native
1362 case-insensitive string comparison function.
1363 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1364 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1366 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1367 strcasecmp() instead of stricmp().
1368 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1369 instead of strcmpi().
1370 * acinclude.m4: Remove the strcasecmp() check from here.
1372 2007-03-21 Paul Smith <psmith@gnu.org>
1374 * configure.in: Don't turn on case-insensitive file system support
1375 if --disable-... is given. Fixes Savannah bug #19348.
1377 2007-03-19 Paul Smith <psmith@gnu.org>
1379 * ALL: Use the strcache for all file name strings, or other
1380 strings which we will never free. The goal is to save memory by
1381 avoiding duplicate copies of strings. However, at the moment this
1382 doesn't save much memory in most situations: due to secondary
1383 expansion we actually save prerequisite lists twice (once before
1384 the secondary expansion, and then again after it's been parsed
1385 into individual file names in the dep list). We will resolve this
1386 in a future change, by doing the parsing up-front for targets
1387 where secondary expansion is not set.
1389 Moving things into the strcache also allows us to use const
1390 pointers in many more places.
1392 2007-01-03 Paul Smith <psmith@gnu.org>
1394 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1395 the function, not just the first. Fixes Savannah bug #18680.
1397 2006-11-18 Paul Smith <psmith@gnu.org>
1399 * strcache.c (strcache_add_len): Don't allocate a new buffer
1400 unless the string is not already nil-terminated. Technically this
1401 is a violation of the standard, since we may be passed an array
1402 that is not long enough to test one past. However, in make this
1403 is never true since we only use nil-terminated strings or
1404 sub-strings thereof.
1406 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1408 * main.c: New global cmd_prefix, defaults to '\t'.
1409 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1412 * dir.c: Constified.
1413 (dir_contents_file_exists_p): Check for an error return from
1414 readdir(), just in case.
1416 * commands.c: Constified.
1417 * default.c: Constified.
1418 * expand.c: Constified.
1419 * function.c: Partial constification.
1420 * variable.c: Partial constification.
1421 * vmsify.c: Constification. Hard to test this but I hope I didn't
1423 * vpath.c: Partial constification.
1424 * w32/pathstuff.c: Partial constification.
1426 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1428 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1429 backslashes and drive letters as absolute.
1431 2006-10-22 Paul Smith <psmith@gnu.org>
1433 * main.c (struct command_switch): Use const and void*.
1435 2006-10-21 Paul Smith <psmith@gnu.org>
1438 * arscan.c: Constified.
1440 2006-09-30 Paul Smith <psmith@gnu.org>
1442 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1443 point to lastword since the example was updated.
1444 Fixes Savannah bug #16304.
1445 (Secondary Expansion): Correct example description.
1446 Fixes Savannah bug #16468.
1447 (Makefile Contents): Clarify that comments cannot appear within
1448 variable references or function calls.
1449 Fixes Savannah bug #16577.
1450 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1451 Fixes Savannah bug #17701.
1452 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1454 prerequisites. Fixes Savannah bug #17880.
1455 (Rule Syntax): "lise" -> "list"
1456 (Multiple Rules): ... -> @dots{}
1457 (Splitting Lines): ditto.

1460 considered changed, for the purposes of $?.
1461 Fixes Savannah bug #16051.
1463 * make.1: Remove extraneous "+".
1464 Fixes Savannah bug #16652.
1466 2006-09-06 Paul D. Smith <psmith@gnu.org>

1481 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1482 sh_chars_sh for Windows platforms that emulate Unix.
1484 2006-05-07 Paul D. Smith <psmith@gnu.org>
1486 * README.OS2.template: Updates provided by Andreas Buening
1487 <andreas.buening@nexgo.de>.

1516 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1517 values from memory allocation functions: they return void* and so
1518 don't need to be cast. Also remove (char *) casts of arguments to
1521 * configure.in: Remove checks for memcpy/memmove/strchr.
1523 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1525 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp

1533 2006-04-06 Paul D. Smith <psmith@gnu.org>
1535 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1536 require an ISO C 1989 standard compiler and runtime library.

1568 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1569 with lastslash, since the latter points to filename, not to

1574 2006-03-23 Paul D. Smith <psmith@gnu.org>

1588 * implicit.c (pattern_search): Call set_file_variables only
1589 if we have prerequisites that need second expansion. Fixes
1590 Savannah bug #16140.
1592 2006-03-19 Paul D. Smith <psmith@gnu.org>
1594 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1595 memory on hosts that don't support it directly.
1597 * README.cvs: Add information on steps for making a release (to
1598 make sure I don't forget any).
1600 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1602 (die): Cleanup code was removed from here; call the new function.
1603 (main): If we are re-execing, clean up the jobserver first so we
1604 don't leak file descriptors.
1605 Reported by Craig Fithian <craig.fithian@citigroup.com>
1607 2006-03-17 Paul D. Smith <psmith@gnu.org>
1609 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1610 allow multiple concurrent runs.
1611 Patch from Joseph Myers <joseph@codesourcery.com>
1613 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1615 * dep.h (struct dep): Add the stem field.
1616 * misc.c (alloc_dep, free_dep): New functions.
1617 (copy_dep_chain): Copy stem.
1618 (free_dep_chain): Use free_dep.
1619 * read.c (record_files): Store stem in the dependency line.
1620 * file.c (expand_deps): Use stem stored in the dependency line. Use
1621 free_dep_chain instead of free_ns_chain.
1622 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1623 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1624 * main.c (main, handle_non_switch_argument): Ditto.
1625 * remake.c (check_dep): Ditto.
1626 * rule.c (convert_suffix_rule, freerule): Ditto.
1628 2006-03-14 Paul D. Smith <psmith@gnu.org>
1630 * expand.c (variable_append): Instead of appending everything then
1631 expanding the result, we expand (or not, if it's simple) each part
1633 (allocated_variable_append): Don't expand the final result.
1634 Fixes Savannah bug #15913.
1636 2006-03-09 Paul Smith <psmith@gnu.org>
1638 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1639 listed non-existent files as changed. Turns out there's a bug in
1640 the Linux kernel builds which means that this change causes
1641 everything to rebuild every time. We will re-introduce this fix
1642 in the next release, to give them time to fix their build system.
1643 Fixes Savannah bug #16002.
1644 Introduces Savannah bug #16051.
1646 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1647 we *don't* find UNIX "/".
1648 Reported by David Ergo <david.ergo@alterface.com>
1650 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1652 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1653 locator function find_and_set_default_shell if SHELL came from the
1656 2006-02-20 Paul D. Smith <psmith@gnu.org>
1658 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1659 to be null; don't core in that case.
1661 2006-02-19 Paul D. Smith <psmith@gnu.org>
1663 * commands.c (set_file_variables): Realloc, not malloc, the static
1664 string values to avoid memory leaks.
1666 * expand.c (recursively_expand_for_file): Only set reading_file to
1667 an initialized value.
1669 * implicit.c (pattern_search): We need to make a copy of the stem
1670 if we get it from an intermediate dep, since those get freed.
1672 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1674 (enter_file) [VMS]: Ditto.
1675 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1677 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1679 * job.c (construct_command_argv_internal): Fix last change.
1681 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1682 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1683 the calls to _beginthreadex.
1685 * expand.c (recursively_expand_for_file): Initialize `save' to
1686 prevent compiler warnings.
1688 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1690 * job.c (construct_command_argv_internal): Don't create a temporary
1691 script/batch file if we are under -n. Call _setmode to switch the
1692 script file stream to text mode.
1694 2006-02-17 Paul D. Smith <psmith@gnu.org>
1696 * variable.c (merge_variable_set_lists): Don't try to merge the
1697 global_setlist. Not only is this useless, but it can lead to
1698 circularities in the linked list, if global_setlist->next in one
1699 list gets set to point to another list which also ends in
1701 Fixes Savannah bug #15757.
1703 2006-02-15 Paul D. Smith <psmith@gnu.org>
1705 Fix for Savannah bug #106.
1707 * expand.c (expanding_var): Keep track of which variable we're
1708 expanding. If no variable is being expanded, it's the same as
1710 * make.h (expanding_var): Declare it.
1711 * expand.c (recursively_expand_for_file): Set expanding_var to the
1712 current variable we're expanding, unless there's no file info in
1713 it (could happen if it comes from the command line or a default
1714 variable). Restore it before we exit.
1715 * expand.c (variable_expand_string): Use the expanding_var file
1716 info instead of the reading_file info.
1717 * function.c (check_numeric): Ditto.
1719 (func_wordlist): Ditto.
1720 (func_error): Ditto.
1721 (expand_builtin_function): Ditto.
1722 (handle_function): Ditto.
1724 2006-02-14 Paul D. Smith <psmith@gnu.org>
1726 * read.c (eval): Even if the included filenames expands to the
1727 empty string we still need to free the allocated buffer.
1729 * implicit.c (pattern_search): If we allocated a variable set for
1730 an impossible file, free it.
1731 * variable.c (free_variable_set): New function.
1732 * variable.h: Declare it.
1734 * read.c (read_all_makefiles): Makefile names are kept in the
1735 strcache, so there's never any need to alloc/free them.
1738 * main.c (main): Add "archives" to the .FEATURES variable if
1739 archive support is enabled.
1740 * doc/make.texi (Special Variables): Document it.
1742 2006-02-13 Paul D. Smith <psmith@gnu.org>
1744 * implicit.c (pattern_search): Add checking for DOS pathnames to
1745 the pattern rule target LASTSLASH manipulation.

1750 * (ALL FILES): Updated copyright and license notices.
1752 2006-02-10 Paul D. Smith <psmith@gnu.org>
1754 A new internal capability: the string cache is a read-only cache
1755 of strings, with a hash table interface for fast lookup. Nothing
1756 in the cache will ever be freed, so there's no need for reference
1757 counting, etc. This is the beginning of a full solution for
1758 Savannah bug #15182, but for now we only store makefile names here.
1760 * strcache.c: New file. Implement a read-only string cache.
1761 * make.h: Add prototypes for new functions.
1762 * main.c (initialize_global_hash_tables): Initialize the string cache.
1763 (print_data_base): Print string cache stats.
1764 * read.c (eval_makefile): Use the string cache to store makefile
1765 names. Rewrite the string allocation to be sure we free everything.
1767 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1769 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1770 directory time stamp didn't change, except on FAT filesystems.
1771 Suggested by J. David Bryan <jdbryan@acm.org>.
1773 2006-02-09 Paul D. Smith <psmith@gnu.org>
1775 * function.c (func_or): Implement a short-circuiting OR function.
1776 (func_and): Implement a short-circuiting AND function.
1777 (function_table_init): Update the table with the new functions.
1778 * doc/make.texi (Conditional Functions): Changed the "if" section
1779 to one on general conditional functions. Added documentation for
1780 $(and ...) and $(or ...) functions.
1781 * NEWS: Note new $(and ...) and $(or ...) functions.
1783 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1785 * job.h (struct child): Add the dontcare bitfield.
1786 * job.c (new_job): Cache dontcare flag.
1787 * job.c (reap_children): Use cached dontcare flag instead of the
1788 one in struct file. Fixes Savannah bug #15641.
1790 2006-02-06 Paul D. Smith <psmith@gnu.org>
1792 * vpath.c (selective_vpath_search): If the file we find has a
1793 timestamp from -o or -W, use that instead of the real time.
1794 * remake.c (f_mtime): If the mtime is a special token from -o or
1795 -W, don't overwrite it with the real mtime.
1796 Fixes Savannah bug #15341.
1798 Updates from Markus Mauhart <qwe123@chello.at>:
1800 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1801 (process_signal, process_last_err, process_exit_code): Manage
1802 invalid handle values.
1803 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1804 manage invalid handles; remove them.

1806 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1807 * README.cvs: Updates for building from CVS.
1809 2006-02-05 Paul D. Smith <psmith@gnu.org>

1813 Fixes Savannah bug #15533.
1814 * filedef.h (struct file): Add a new LAST pointer.
1816 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1817 the comparison. For 64-bits systems the result of the subtraction
1818 might not fit into an int. Use comparison instead.
1819 Fixes Savannah bug #15534.
1821 * doc/make.texi: Update the chapter on writing commands to reflect
1822 the changes made in 3.81 for backslash/newline and SHELL handling.
1824 2006-02-01 Paul D. Smith <psmith@gnu.org>
1826 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1842 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1844 * remake.c (update_goal_chain): Set g->changed instead of
1845 incrementing it, as it is only 8-bit wide, and could overflow if
1846 many commands got started in update_file.
1848 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1850 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1851 MAXIMUM_WAIT_OBJECTS.
1852 (process_wait_for_any_private): Change dimension of handles[]
1853 array to MAXIMUM_WAIT_OBJECTS.
1854 (process_used_slots): New function.
1855 (process_register): Don't register more processes than the
1856 available number of slots.
1857 (process_easy): Don't start new processes if all slots are used up.
1859 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1860 are already more children than sub_proc.c can handle, behave as if
1861 the load were too high.
1862 (start_job_command): Fix a typo in error message when process_easy
1865 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1867 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1868 the shell is not sh.exe.
1870 * job.c (create_batch_file): Renamed from create_batch_filename;
1871 all callers changed. Don't close the temporary file; return its
1872 file descriptor instead. New arg FD allows to return the file
1874 (construct_command_argv_internal): Use _fdopen instead of fopen to
1875 open the batch file.
1877 2006-01-04 Paul D. Smith <psmith@gnu.org>
1879 * readme.vms: Updates for case-insensitive VMS file systems from
1880 Hartmut Becker <Hartmut.Becker@hp.com>.
1881 * dir.c (vms_hash): Ditto.
1882 * vmsify.c (copyto): Ditto.

1900 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1901 disable warnings for MSC.
1902 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1904 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1906 * doc/make.texi (Execution): Add a footnote about changes in
1907 handling of backslash-newline sequences. Mention the differences
1908 on MS-DOS and MS-Windows.
1910 * NEWS: More details about building the MinGW port and a pointer
1911 to README.W32. Fix the section name that describes the new
1912 backward-incompatible processing of backslash-newline sequences.
1913 The special processing of SHELL set to "cmd" is only relevant to
1914 MS-Windows, not MS-DOS.
1916 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1918 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1919 to DWORD, to avoid compiler warnings.
1920 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1921 use %ld in format, to avoid compiler warnings.
1923 * doc/make.texi (Special Targets): Fix a typo.
1924 (Appending): Fix cross-reference to Setting.
1925 (Special Variables, Secondary Expansion, File Name Functions)

1935 * read.c (record_target_var): Initialize variable's export field
1936 with v_default instead of leaving it "initialized" by whatever
1937 garbage happened to be on the heap.

1941 * make.1: Fix some display errors and document all existing options.
1942 Patch by Mike Frysinger <vapier@gentoo.org>.
1944 2005-12-11 Paul D. Smith <psmith@gnu.org>
1946 * implicit.c (pattern_search): If 2nd expansion is not set for
1947 this implicit rule, replace the pattern with the stem directly,
1948 and don't re-expand the variable list. Along with the other
1949 .SECONDEXPANSION changes below, fixes bug #13781.
1951 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1953 * implicit.c (pattern_search): Mark other files that this rule
1954 builds as targets so that they are not treated as intermediates
1955 by the pattern rule search algorithm. Fixes bug #13022.
1957 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1959 * remake.c (notice_finished_file): Propagate the change of

1979 * read.c (record_files): Don't set deps flags if there are no deps.
1980 * maintMakefile: We only need to build the templates when we are
1981 creating a distribution, so don't do it for "all".
1983 2005-10-24 Paul D. Smith <psmith@gnu.org>
1985 Make secondary expansion optional: its enabled by declaring the
1986 special target .SECONDEXPANSION.
1988 * NEWS: Update information on second expansion capabilities.
1989 * doc/make.texi (Secondary Expansion): Document the
1990 .SECONDEXPANSION special target and its behavior.

1993 (free_dep_chain): Declare a prototype.
1994 * file.c (parse_prereqs): New function: break out some complexity
1996 (expand_deps): If we aren't doing second expansion, replace % with
1997 the stem for static pattern rules. Call the new function.
1998 * filedef.h (parse_prereqs): Declare a prototype.
1999 * implicit.c (pattern_search): Initialize the new staticpattern
2001 * main.c (second_expansion): Declare a global variable to remember
2002 if the special target has been seen. Initialize the new
2003 staticpattern field for prerequisites.
2004 * make.h: Extern for second_expansion.
2005 * misc.c (free_dep_chain): New function: frees a struct dep list.
2006 * read.c (read_all_makefiles): Initialize the staticpattern field.
2007 (eval_makefile): Ditto.
2008 (record_files): Check for the .SECONDEXPANSION target and set

2010 Use the new free_dep_chain() instead of doing it by hand.
2011 Set the staticpattern field for prereqs of static pattern targets.
2013 2005-10-16 Paul D. Smith <psmith@gnu.org>
2015 * main.c (main): Set CURDIR to be a file variable instead of a
2016 default, so that values of CURDIR inherited from the environment
2017 won't override the make value.
2019 2005-09-26 Paul D. Smith <psmith@gnu.org>
2021 * job.c (construct_command_argv_internal): If the line is empty
2022 remember to free the temporary argv strings.
2025 2005-09-16 Paul D. Smith <psmith@gnu.org>
2027 * job.c (start_job_command): The noerror flag is a boolean (single
2028 bit); set it appropriately.
2029 Reported by Mark Eichin <eichin@metacarta.com>
2031 2005-08-29 Paul D. Smith <psmith@gnu.org>
2033 * function.c (func_error): On Windows, output from $(info ...)
2034 seems to come in the wrong order. Try to force it with fflush().
2036 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2038 * read.c (record_files): Move code that sets stem for static
2039 pattern rules out of the if (!two_colon) condition so it is
2040 also executed for two-colon rules. Fixes Savannah bug #13881.
2042 2005-08-08 Paul D. Smith <psmith@gnu.org>
2044 * make.h: Don't test that __STDC__ is non-0. Some compilers
2045 (Windows for example) set it to 0 to denote "ISO C + extensions".
2048 2005-08-07 Paul D. Smith <psmith@gnu.org>
2050 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2051 conditional (slightly different version of a fix from Eli).
2053 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2054 If make is running in parallel without -k and two jobs die in a
2055 row, but not too close to each other, then make will quit without
2056 waiting for the rest of the jobs to die.
2058 * main.c (die): Don't reset err before calling reap_children() the
2059 second time: we still want it to be in the error condition.
2060 * job.c (reap_children): Use a static variable, rather than err,
2061 to control whether or not the error message should be printed.
2063 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2065 * w32/subproc/sub_proc.c: Include signal.h.
2066 (process_pipe_io, process_file_io): Pass a pointer to a local
2067 DWORD variable to GetExitCodeProcess. If the exit code is
2068 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2070 * job.c [WINDOWS32]: Include windows.h.
2071 (main_thread) [WINDOWS32]: New global variable.
2072 (reap_children) [WINDOWS32]: Get the handle for the main thread
2073 and store it in main_thread.
2075 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2076 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2077 doing anything else. When we are done, close the main thread
2078 handle and exit with status 130.
2080 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2082 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2085 * main.c (find_and_set_default_shell): If found a DOSish shell,
2086 set sh_found and the value of default_shell, and report the
2087 findings in debug mode.
2089 * job.c (construct_command_argv_internal): Check unixy_shell, not
2090 no_default_sh_exe, to decide whether to use Unixy or DOSish
2093 * README.W32: Update with info about the MinGW build.
2095 * build_w32.bat: Support MinGW.
2097 * w32/subproc/build.bat: Likewise.
2099 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2100 printing DWORD args.
2102 * function.c (windows32_openpipe): Fix format strings for printing
2105 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2107 (start_job_command): Fix format string for printing the result of
2109 (start_job_command) [WINDOWS32]: Do not define.
2110 (exec_command): Fix format string for printing HANDLE args.
2112 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2113 to avoid compiler warnings.
2114 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2115 (Note: some of these fixes were submitted independently by J. Grant)
2117 2005-07-30 J. Grant <jg@jguk.org>
2119 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2120 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2121 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2123 2005-07-15 Paul Smith <psmith@gnu.org>
2125 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2126 we don't have a POSIX shell, then revert to the old
2127 backslash-newline behavior (where they are stripped).
2130 2005-07-08 Paul D. Smith <psmith@gnu.org>
2132 * config.h.W32.template: Reorder to match the standard config.h,
2133 for easier comparisons.
2134 From J. Grant <jg@jguk.org>
2136 * maintMakefile: Remove .dep_segment before overwriting it, in
2137 case it's not writable or noclobber is set.
2138 * expand.c (variable_expand_string): Cast result of pointer
2139 arithmetic to avoid a warning.
2140 * main.c (switches): Add full-fledged final initializer.
2142 2005-07-06 Paul D. Smith <psmith@gnu.org>
2144 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2145 * signame.c (strsignal): If we found _sys_siglist[] or
2146 __sys_siglist[] use those instead of sys_siglist[].
2147 From Albert Chin <china@thewrittenword.com>
2149 2005-07-04 Paul D. Smith <psmith@gnu.org>
2151 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2152 globfree(); set up to use the GNU versions.
2153 From Martin Zinser <zinser@zinser.no-ip.info>
2155 2005-07-03 Paul D. Smith <psmith@gnu.org>
2157 From J. Grant <jg@jguk.org>:
2159 * README.W32.template: Update the Windows and tested MSVC versions.
2160 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2161 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2162 * build_w32.bat: Ditto.
2163 * w32/subproc/build.bat: Ditto.
2165 2005-06-28 Paul D. Smith <psmith@gnu.org>
2167 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2168 declaration was checked but not present.
2170 2005-06-27 Paul D. Smith <psmith@gnu.org>
2172 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2173 to unsigned long. Fixes Savannah bug #13550.
2175 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2176 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2177 Fixes Savannah bug #13551.
2179 2005-06-26 Paul D. Smith <psmith@gnu.org>
2181 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2182 it if ANSI_STRING is not set.
2184 2005-06-25 Paul D. Smith <psmith@gnu.org>
2186 * read.c (eval): If no filenames are passed to any of the
2187 "include" variants, don't print an error.
2188 * doc/make.texi (Include): Document this.
2189 Fixes Savannah bug #1761.
2191 * job.c (construct_command_argv_internal): Sanitize handling of
2192 backslash/newline pairs according to POSIX: that is, keep the
2193 backslash-newline in the command script, but remove a following
2194 TAB character, if present. In the fast path, make sure that the
2195 behavior matches what the shell would do both inside and outside
2196 of quotes. In the slow path, quote the backslash and put a
2197 literal newline in the string.
2198 Fixes Savannah bug #1332.
2199 * doc/make.texi (Execution): Document the new behavior and give
2201 * NEWS: Make a note of the new behavior.
2203 * make.h [WINDOWS32]: #include <direct.h>.
2204 Fixes Savannah bug #13478.
2206 * remake.c (name_mtime): If the stat() of a file fails and the -L
2207 option was given and the file is a symlink, take the best mtime of
2208 the symlink we can get as the mtime of the file and don't fail.
2209 Fixes Savannah bug #13280.
2211 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2212 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2213 inside a variable reference. Make this function static as it's
2215 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2216 parsing an unexpanded line looking for semicolons.
2217 Fixes Savannah bug #1454.
2218 * misc.c (remove_comments): Move this to read.c and make it static
2219 as it's only used there. Call find_char_unquote() with new arg.
2220 * make.h: Remove prototypes for find_char_unquote() and
2221 remove_comments() since they're static now.
2223 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2224 its export flag and obtain its value. When we need to re-exec,
2225 increment the value and add it into the environment.
2226 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2227 * NEWS: Mention MAKE_RESTARTS.
2228 * main.c (always_make_set): New variable. Change the -B option to
2229 set this one instead.
2230 (main): When checking makefiles, only set always_make_flag if
2231 always_make_set is set AND the restarts flag is 0. When building
2232 normal targets, set it IFF always_make_set is set.
2233 (main): Avoid infinite recursion with -W, too: only set what-if
2234 files to NEW before we check makefiles if we've never restarted
2235 before. If we have restarted, set what-if files to NEW _after_ we
2237 Fixes Savannah bug #7566:
2239 2005-06-17 Paul D. Smith <psmith@gnu.org>
2241 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2242 in the prerequisites list.
2244 2005-06-12 Paul D. Smith <psmith@gnu.org>
2246 Fix Savannah bug # 1328.
2248 * configure.in: Check for atexit().
2249 * misc.c (close_stdout): Test stdout to see if writes to it have
2250 failed. If so, be sure to exit with a non-0 error code. Based on
2251 code found in gnulib.
2252 * make.h: Prototype.
2253 * main.c (main): Install close_stdout() with atexit().
2255 2005-06-10 Paul D. Smith <psmith@gnu.org>
2257 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2259 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2260 headers; make vmsWaitForChildren() static; extern vmsify().
2261 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2262 Don't create child_execute_job() here (it's in vmsjobs.c).
2263 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2265 2005-06-09 Paul D. Smith <psmith@gnu.org>
2267 * variable.c (push_new_variable_scope): File variables point
2268 directly to the global_setlist variable. So, inserting a new
2269 scope in front of that has no effect on those variables: they
2270 don't go through current_variable_set_list. If we're pushing a
2271 scope and the current scope is global, push it "the other way" so
2272 that the new setlist is in the global_setlist variable, and
2273 next points to a new setlist with the global variable set.
2274 (pop_variable_scope): Properly undo a push with the new
2276 Fixes Savannah bug #11913.
2278 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2280 * job.c (reap_children): Don't die of the command failed but
2281 the dontcare flag is set. Fixes Savannah bug #13216.
2283 * implicit.c (pattern_search): When creating a target from
2284 an implicit rule match, lookup pattern target and set precious
2285 flag in a newly created target. Fixes Savannah bug #13218.
2287 2005-05-13 Paul D. Smith <psmith@gnu.org>
2289 Implement "if... else if... endif" syntax.
2291 * read.c (eval): Push all checks for conditional words ("ifeq",
2292 "else", etc.) down into the conditional_line() function.
2293 (conditional_line): Rework to allow "else if..." clause. New
2294 return value -2 for lines which are not conditionals. The
2295 ignoring flag can now also be 2, which means "already parsed a
2296 true branch". If that value is seen no other branch of this
2297 conditional can be considered true. In the else parsing if there
2298 is extra text after the else, invoke conditional_line()
2299 recursively to see if it's another conditional. If not, it's an
2300 error. If so, raise the conditional value to this level instead
2301 of creating a new conditional nesting level. Special check for
2302 "else" and "endif", which aren't allowed on the "else" line.
2303 * doc/make.texi (Conditional Syntax): Document the new syntax.
2305 2005-05-09 Paul D. Smith <psmith@gnu.org>
2307 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2308 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2309 recurses to the w32 directory, even on non-Windows systems. Use
2310 the method suggested in the automake manual.
2311 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2312 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2314 2005-05-07 Paul D. Smith <psmith@gnu.org>
2316 * main.c (die): If we're dying with a fatal error (not that a
2317 command has failed), write back any leftover tokens before we go.
2319 * job.c (set_child_handler_action_flags): If there are jobs
2320 waiting for the load to go down, set an alarm to go off in 1
2321 second. This allows us to wake up from a potentially long-lasting
2322 read() and start a new job if the load has gone down. Turn it off
2324 (job_noop): Dummy signal handler function.
2325 (new_job): Invoke it with the new semantics.
2327 * docs/make.texi: Document secondary expansion. Various cleanups
2330 2005-05-03 Paul D. Smith <psmith@gnu.org>
2332 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2333 the targets which are to ultimately be made are called "goals";
2334 see the GNU make manual. Also, MAKECMDGOALS, etc.
2336 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2337 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2338 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2340 2005-05-02 Paul D. Smith <psmith@gnu.org>
2342 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2343 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2344 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2345 functions to vmsjobs.c. #include it into jobs.c.
2347 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2348 jobserver tokens. I found that this happens when an exported
2349 recursive variable contains a $(shell ...) function reference: in
2350 this situation we could "forget" to write back a token.
2352 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2353 we have. It's not reliable to depend on the number of children in
2354 our linked list so keep a separate count.
2355 (new_job): Check jobserver_tokens rather than children &&
2356 waiting_jobs. Increment jobserver_tokens when we get one.
2357 (free_child): If jobserver_tokens is 0, internal error. If it's
2358 >1, write a token back to the jobserver pipe (we don't write a
2359 token for the "free" job). Decrement jobserver_tokens.
2361 * main.c: Add variable master_job_slots.
2362 (main): Set it to hold the number of jobs requested if we're the
2363 master process, when using the jobserver.
2364 (die): Sanity checks: first test jobserver_tokens to make sure
2365 this process isn't holding any tokens we didn't write back.
2366 Second, if master_job_slots is set count the tokens left in the
2367 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2369 2005-04-24 Paul D. Smith <psmith@gnu.org>
2371 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2372 with -l# can lose jobserver tokens, because waiting jobs are not
2373 consulted properly when checking for the "free" token.
2375 * job.c (free_child): Count waiting_jobs as having tokens.
2376 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2377 handle jobs waiting for the load to drop.
2379 2005-04-23 Paul D. Smith <psmith@gnu.org>
2381 * main.c (main): Be careful to not core if a variable setting in
2382 the environment doesn't contain an '='. This is illegal but can
2383 happen in broken setups.
2384 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2386 2005-04-12 Paul D. Smith <psmith@gnu.org>
2388 The second expansion feature causes significant slowdown. Timing
2389 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2390 read the makefile before the feature, to 11+s to do the same
2391 operations after the feature. Additionally, memory usage
2392 increased drastically. To fix this I added some intelligence that
2393 avoids the overhead of the second expansion unless it's required.
2395 * dep.h: Add a new boolean field, need_2nd_expansion.
2397 * read.c (eval): When creating the struct dep for the target,
2398 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2399 (record_files): If there's a "%" in a static pattern rule, it gets
2400 converted to "$*" so set need_2nd_expansion to 1.
2402 * file.c (expand_deps): Rework to be more efficient. Only perform
2403 initialize_file_variables(), set_file_variables(), and
2404 variable_expand_for_file() if the need_2nd_expansion is set.
2406 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2407 (pattern_search): Ditto.
2408 * main.c (handle_non_switch_argument): Ditto.
2410 * read.c (read_all_makefiles): Ditto.
2411 (eval_makefile): Ditto.
2413 2005-04-07 Paul D. Smith <psmith@gnu.org>
2415 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2416 * variable.c (sync_Path_environment): Ditto.
2417 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2419 * main.c (main): Define the .FEATURES variable.
2420 * NEWS: Announce .FEATURES.
2421 * doc/make.texi (Special Variables): Document .FEATURES.
2423 * remake.c (check_dep): If a file is .PHONY, update it even if
2424 it's marked intermediate. Fixes Savannah bug #12331.
2426 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2428 * file.c (expand_deps): Factor out the second expansion and
2429 prerequisite line parsing logic from snap_deps().
2431 * file.c (snap_deps): Use expand_deps(). Expand and parse
2432 prerequisites of the .SUFFIXES special target first. Fixes
2433 Savannah bug #12320.
2435 2005-03-13 Paul D. Smith <psmith@gnu.org>
2437 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2440 2005-03-11 Paul D. Smith <psmith@gnu.org>
2442 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2443 available, not undefined (from Earnie Boyd).
2445 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2447 * implicit.c (pattern_search): Mark an intermediate target as
2448 precious if it happened to be a prerequisite of some (other)
2449 target. Fixes Savannah bug #12267.
2451 2005-03-09 Paul D. Smith <psmith@gnu.org>
2453 * read.c (eval_makefile): Add alloca(0).
2454 (eval_buffer): Ditto.
2456 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2458 * main.c (main): Use o_file instead of o_default when defining
2459 the .DEFAULT_TARGET special variable.
2460 * read.c (eval): Use define_variable_global() instead of
2461 define_variable() when setting new value for the .DEFAULT_TARGET
2462 special variable. Fixes Savannah bug #12266.
2464 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2466 * imlicit.c (pattern_search): Mark files for which an implicit
2467 rule has been found as targets. Fixes Savannah bug #12202.
2469 2005-03-04 Paul D. Smith <psmith@gnu.org>
2472 * doc/make.texi (Automatic Variables): Document $|.
2474 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2476 * read.c (record_files): Instead of substituting % with
2477 actual stem value in dependency list replace it with $*.
2478 This fixes stem triple expansion bug.
2480 * implicit.c (pattern_search): Copy stem to a separate
2481 buffer and make it a properly terminated string. Assign
2482 this buffer instead of STEM (which is not terminated) to
2483 f->stem. Instead of substituting % with actual stem value
2484 in dependency list replace it with $*. This fixes stem
2485 triple expansion bug.
2487 2005-03-01 Paul D. Smith <psmith@gnu.org>
2489 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2490 on Windows, as it takes a handle not a pid. Just exit.
2491 Fix from patch #3679, provided by Alessandro Vesely.
2493 * configure.in: Update check for sys_siglist[] from autoconf manual.
2494 * signame.c (strsignal): Update to use the new autoconf macro.
2496 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2498 * read.c (record_files): Add a check for the list of prerequisites
2499 of a static pattern rule being empty. Fixes Savannah bug #12180.
2501 2005-02-28 Paul D. Smith <psmith@gnu.org>
2503 * doc/make.texi (Text Functions): Update docs to allow the end
2504 ordinal for $(wordlist ...) to be 0.
2505 * function.c (func_wordlist): Fail if the start ordinal for
2506 $(wordlist ...) is <1. Matches documentation.
2507 Resolves Savannah support request #103195.
2509 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2510 previously we were stopping when !-q, exactly the opposite. This
2511 has been wrong since version 1.34, in 1994!
2512 (update_file): If we got an error don't break out to run more
2513 double-colon rules: just return immediately.
2514 Fixes Savannah bug #7144.
2516 2005-02-27 Paul D. Smith <psmith@gnu.org>
2518 * misc.c (end_of_token): Make argument const.
2519 * make.h: Update prototype.
2521 * function.c (abspath, func_realpath, func_abspath): Use
2522 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2523 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2524 * read.c (record_files): Ditto.
2525 * variable.c (do_variable_definition): Ditto.
2527 * function.c (func_error): Create a new function $(info ...) that
2528 simply prints the message to stdout with no extras.
2529 (function_table_init): Add new function to the table.
2530 * NEWS: Add $(info ...) reference.
2531 * doc/make.texi (Make Control Functions): Document it.
2533 New feature: if the system supports symbolic links, and the user
2534 provides the -L/--check-symlink-time flag, then use the latest
2535 mtime between the symlink(s) and the target file.
2537 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2538 readlink(). If both are available, define MAKE_SYMLINKS.
2539 * main.c: New variable: check_symlink_flag.
2540 (usage): Add a line for -L/--check-symlink-times to the help string.
2541 (switches): Add -L/--check-symlink-times command line argument.
2542 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2543 print a warning and disable it again.
2544 * make.h: Declare check_symlink_flag.
2545 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2546 if the file is a symlink then check each link in the chain and
2547 choose the NEWEST mtime we find as the mtime for the file. The
2548 newest mtime might be the file itself!
2549 * NEWS: Add information about this new feature.
2550 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2552 Avoid core dumps described in Savannah bug # 12124:
2554 * file.c: New variable snapped_deps remember whether we've run
2556 (snap_deps): Set it.
2557 * filedef.h: Extern it.
2558 * read.c (record_files): Check snapped_deps; if it's set then
2559 we're trying to eval a new target/prerequisite relationship from
2560 within a command script, which we don't support. Fatal.
2562 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2564 Implementation of the .DEFAULT_TARGET special variable.
2566 * read.c (eval): If necessary, update default_target_name when
2568 * read.c (record_files): Update default_target_file if
2569 default_target_name has changed.
2570 * main.c (default_target_name): Define.
2571 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2572 default_target_name is set use default_target_file as a root
2574 * filedef.h (default_target_name): Declare.
2575 * dep.h (free_dep_chain):
2576 * misc.c (free_dep_chain): Change to operate on struct nameseq
2577 and change name to free_ns_chain.
2578 * file.c (snap_deps): Update to use free_ns_chain.
2580 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2582 Implementation of the second expansion in explicit rules,
2583 static pattern rules and implicit rules.
2585 * read.c (eval): Refrain from chopping up rule's dependencies.
2586 Store them in a struct dep as a single dependency line. Remove
2587 the code that implements SySV-style automatic variables.
2589 * read.c (record_files): Adjust the code that handles static
2590 pattern rules to expand all percents instead of only the first
2591 one. Reverse the order in which dependencies are stored so that
2592 when the second expansion reverses them again they appear in
2593 the makefile order (with some exceptions, see comments in
2594 the code). Remove the code that implements SySV-style automatic
2597 * file.c (snap_deps): Implement the second expansion and chopping
2598 of dependency lines for explicit rules.
2600 * implicit.c (struct idep): Define an auxiliary data type to hold
2601 implicit rule's dependencies after stem substitution and
2604 * implicit.c (free_idep_chain): Implement.
2606 * implicit.c (get_next_word): Implement helper function for
2607 parsing implicit rule's dependency lines into words taking
2608 into account variable expansion requests. Used in the stem
2611 * implicit.c (pattern_search): Implement the second expansion
2612 for implicit rules. Also fixes bug #12091.
2614 * commands.h (set_file_variables): Declare.
2615 * commands.c (set_file_variables): Remove static specifier.
2617 * dep.h (free_dep_chain): Declare.
2618 * misc.c (free_dep_chain): Implement.
2620 * variable.h (variable_expand_for_file): Declare.
2621 * expand.c (variable_expand_for_file): Remove static specifier.
2623 * make.h (strip_whitespace): Declare.
2624 * function.c (strip_whitespace): Remove static specifier.
2626 2005-02-26 Paul D. Smith <psmith@gnu.org>
2628 * main.c (main): Check for ferror() when reading makefiles from stdin.
2629 Apparently some shells in Windows don't close pipes properly and
2632 2005-02-24 Jonathan Grant <jg@jguk.org>
2634 * configure.in: Add MinGW configuration options, and extra w32 code
2636 * Makefile.am: Add MinGW configuration options, and extra w32 code
2638 * main.c: Determine correct program string (after last \ without .exe).
2639 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2641 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2642 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2643 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2644 environment support.
2646 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2648 * function.c (func_shell): When initializing error_prefix, check
2649 that reading file name is not null. This fixes long-standing
2650 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2652 2005-02-09 Paul D. Smith <psmith@gnu.org>
2654 * maintMakefile: Update the CVS download URL to simplify them.
2655 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2656 downloading the .texi files from Savannah now.
2658 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2660 * main.c (handle_non_switch_argument): Only add variables to
2661 command_variables if they're not already there: duplicate settings
2662 waste space and can be confusing to read.
2664 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2665 this header is never included by non-WINDOWS32 code, and it
2666 requires <config.h> to define which isn't always included first.
2668 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2669 testing MINGW32 versions.
2671 * main.c (log_working_directory): flush stdout to be sure the WD
2672 change is printed before any stderr messages show up.
2674 2005-02-01 Paul D. Smith <psmith@gnu.org>
2676 * maintMakefile (po_repo): Update the GNU translation site URL.
2678 2004-12-01 Paul D. Smith <psmith@gnu.org>
2680 * main.c (main): Change char* env_shell to struct variable shell_var.
2681 * variable.c (target_environment): Use new shell_var.
2683 2004-11-30 Paul D. Smith <psmith@gnu.org>
2685 * configure.in: The old way we avoided creating build.sh from
2686 build.sh.in before build.sh.in exists doesn't work anymore; we
2687 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2688 the help!). This also keeps automake from complaining.
2689 * Makefile.am (README): Add a dummy target so automake won't
2690 complain that this file doesn't exist when we checkout from CVS.
2691 * maintMakefile (.dep_segment): Rewrite this rule since newer
2692 versions of automake don't provide DEP_FILES.
2694 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2696 Implementation of `realpath' and `abspath' built-in functions.
2698 * configure.in: Check for realpath.
2699 * function.c (abspath): Return an absolute file name that does
2700 not contain any `.' or `..' components, nor repeated `/'.
2701 * function.c (func_abspath): For each name call abspath.
2702 * function.c (func_realpath): For each name call realpath
2703 from libc or delegate to abspath if realpath is not available.
2704 * doc/make.texi (Functions for File Names): Document new functions.
2705 * doc/make.texi (Quick Reference): Ditto.
2707 2004-11-28 Paul D. Smith <psmith@gnu.org>
2709 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2710 arguments. Fixes bug #10252.
2712 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2714 * main.c (main): Set SHELL to v_noexport by default. Remember the
2715 original environment setting of SHELL in the env_shell variable.
2716 * main.h: Export new env_shell variable.
2717 * variable.c (target_environment): If we find a v_noexport
2718 variable for SHELL, add a SHELL variable with the env_shell value.
2719 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2720 * doc/make.texi (Variables/Recursion): Ditto.
2722 2004-11-28 Paul D. Smith <psmith@gnu.org>
2724 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2725 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2726 Patch by Alessandro Vesely.
2728 2004-11-12 Paul D. Smith <psmith@gnu.org>
2730 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2731 the command line if it's inside a string.
2732 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2734 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2736 * function.c (func_lastword): New function: return last word
2737 from the list of words.
2738 * doc/make.texi: Document $(lastword ). Fix broken links in
2739 Quick Reference section.
2741 2004-10-06 Paul D. Smith <psmith@gnu.org>
2743 Apply patch from Alessandro Vesely, provided with bug # 9748.
2744 Fix use of tmpnam() to work with Borland C.
2746 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2747 construction of a temporary filename, and call new function
2748 create_batch_filename().
2749 (create_batch_filename) [WINDOWS32]: New function to create a
2752 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2754 * read.c (record_target_var): Expand simple pattern-specific
2756 * variable.c (initialize_file_variables): Do not expand simple
2757 pattern-specific variable.
2759 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2761 * remake.c (update_file_1): When rebuilding makefiles inherit
2762 dontcare flag from a target that triggered update.
2764 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2766 * variable.c (initialize_file_variables): Mark pattern-specific
2767 variable as a per-target and copy export status.
2769 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2771 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2773 * implicit.c (pattern_search): When considering an implicit rule's
2774 prerequisite check that it is actually a target rather then
2775 just an entry in the file hashtable.
2777 2004-09-21 Paul D. Smith <psmith@gnu.org>
2779 * read.c (readstring): Fix some logic errors in backslash handling.
2780 (eval): Remove some unnecessary processing in buffer handling.
2781 (record_target_var): Assert that parse_variable_definition() succeeded.
2782 Reported by: Markus Mauhart <qwe123@chello.at>.
2784 * misc.c: Removed the sindex() function. All instances of this
2785 function were trivially replaceable by the standard strstr()
2786 function, and that function will always have better (or certainly
2787 no worse) performance than the very simple-minded algorithm
2788 sindex() used. This can matter with complex makefiles.
2789 * make.h: Remove the prototype for sindex().
2790 * function.c (subst_expand): Convert sindex() call to strstr().
2791 This means we no longer need to track the TLEN value so remove that.
2792 (func_findstring): Convert sindex() to strstr().
2793 * commands.c (chop_commands): Convert sindex() calls to strstr().
2794 Suggested by: Markus Mauhart <qwe123@chello.at>.
2796 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2797 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2798 If SHELL is set to CMD.EXE then assume it's batch-mode and
2799 non-unixy. I wrote the code differently from the patch, though,
2800 to make it safer. This also resolves bug #9174.
2802 2004-09-20 Paul D. Smith <psmith@gnu.org>
2804 * expand.c (variable_expand_string): Modify to invoke
2805 patsubst_expand() instead of subst_expand(); the latter didn't
2806 handle suffix patterns correctly.
2807 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2808 was used only from variable_expand_string() and is no longer used
2810 (func_subst): Ditto, on call to subst_expand().
2811 (patsubst_expand): Require the percent pointers to point to the
2812 character after the %, not to the % itself.
2813 * read.c (record_files): New call criteria for patsubst_expand().
2814 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2815 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2817 2004-09-19 Paul D. Smith <psmith@gnu.org>
2819 * function.c (subst_expand): Fix a check in by_word: look for a
2820 previous blank if we're beyond the beginning of the string, not
2821 the beginning of the word.
2822 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2824 2004-05-16 Paul D. Smith <psmith@gnu.org>
2826 * remake.c (update_goal_chain): Change the argument specifying
2827 whether we're rebuilding makefiles to be a global variable,
2828 REBUILDING_MAKEFILES.
2829 (complain): Extract the code that complains about no rules to make
2830 a target into a separate function.
2831 (update_file_1): If we tried to rebuild a file during the makefile
2832 rebuild phase and it was dontcare, then no message was printed.
2833 If we then try to build the same file during the normal build,
2834 print a message this time.
2835 (remake_file): Don't complain about un-remake-able files when
2836 we're rebuilding makefiles.
2838 2004-05-11 Paul D. Smith <psmith@gnu.org>
2840 * job.c (construct_command_argv_internal): OS/2 patches from
2841 Andreas Buening <andreas.buening@nexgo.de>.
2843 2004-05-10 Paul D. Smith <psmith@gnu.org>
2845 * remake.c (update_file): Don't walk the double-colon chain unless
2846 this is a double-colon rule. Fix suggested by Boris Kolpackov
2847 <boris@kolpackov.net>.
2849 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2850 * readme.vms: New section describing OpenVMS support and issues.
2851 * default.c (default_variables): Add support for IA64.
2852 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2853 without some privilege aborts make with the error
2854 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2855 pressing Ctrl+Y and the input device is no terminal. The change
2856 catches this error and just continues.
2858 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2860 2004-04-25 Paul D. Smith <psmith@gnu.org>
2862 * commands.c (set_file_variables): Set $< properly in the face of
2863 order-only prerequisites.
2864 Patch from Boris Kolpackov <boris@kolpackov.net>
2866 2004-04-21 Bob Byrnes <byrnes@curl.com>
2868 * main.c (main): Notice failures to remake makefiles.
2870 2004-03-28 Paul D. Smith <psmith@gnu.org>
2872 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2874 * job.c: No default shell for RISC OS.
2875 (load_too_high): Hard-code the return to 1.
2876 (construct_command_argv_internal): No sh_chars or sh_cmds.
2877 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2879 2004-03-20 Paul D. Smith <psmith@gnu.org>
2881 * variable.c (do_variable_definition): Don't append from the
2882 global set if a previous non-appending target-specific variable
2883 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2886 * expand.c (reference_variable): Don't give up on variables with
2887 no value that have the target-specific append flag set: they might
2888 have a value after all. Reported by Oliver Schmidt
2889 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2890 <nikulin@dx1cmd.inp.nsk.su>.
2892 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2893 refer to absolute pathnames in directories that don't exist: some
2894 portion of the makefile could create those directories before we
2895 match the pattern. Fixes bugs #775 and #108.
2897 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2899 * main.c (main): Free makefile_mtimes if we have any.
2900 * README.W32.template: Update documentation for the current status
2901 of the MS-Windows port.
2902 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2903 environment variable is sometimes already defined which causes the
2905 * main.c (debug_signal_handler): Only define this function if
2906 SIGUSR1 is available.
2908 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2910 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2911 * README.OS2.template: Documentation updates.
2912 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2913 link line for safety.
2914 * maintMakefile (build.sh.in): Remove an extraneous ")".
2915 * job.c (child_execute_job): Close saved FDs.
2916 * job.c (exec_command) [OS/2]: exec_command(): If the command
2917 can't be exec'ed and if the shell is not Unix-sh, then try again
2918 with argv = { "cmd", "/c", ... }. Normally, this code is never
2919 reached for the cmd shell unless the command really doesn't exist.
2920 (construct_command_argv_internal) [OS/2]: The code for cmd
2921 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2922 The CMD builtin commands are case insensitive so use strcasecmp().
2924 2004-03-19 Paul D. Smith <psmith@gnu.org>
2926 * read.c (do_define): Re-order line counter increment so the count
2927 is accurate (we were losing one line per define). Reported by
2928 Dave Yost <Dave@Yost.com>.
2930 2004-03-06 Paul D. Smith <psmith@gnu.org>
2932 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2934 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2935 * misc.c (message,error,fatal): Ditto.
2936 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2937 * config.h.W32.template: Ditto.
2938 * config.h-vms.template: Ditto.
2939 * config.ami.template: Ditto.
2941 2004-03-04 Paul D. Smith <psmith@gnu.org>
2943 * README.template: Add a note about broken /bin/sh on SunOS
2944 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2946 * misc.c (message, error, fatal): Don't use "..." if we're using
2947 varargs. ansi2knr should handle this but it doesn't work: it
2948 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2949 done. On many systems (SunOS for example) va_dcl is a #define.
2950 So, force the use of the non-"..." version on pre-ANSI compilers.
2952 * maintMakefile (sign-dist): Create some rules to help automate
2953 the new GNU ftp upload method.
2955 2004-02-24 Paul D. Smith <psmith@gnu.org>
2957 * config.h.W32.template: Add HAVE_STDARG_H
2958 * config.h-vms.template: Ditto.
2959 * config.ami.template: Ditto.
2961 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2963 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2964 * build_w32.bat: Remove extra "+".
2966 2004-02-23 Paul D. Smith <psmith@gnu.org>
2968 * make.h: Create an UNUSED macro to mark unused parameters.
2969 * (many): Clean up warnings by applying UNUSED, fixing
2970 signed/unsigned incompatibilities, etc.
2972 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2974 * filedef.h: Name the command_state enumeration.
2975 * file.c (set_command_state): Use the enumeration in the function
2978 * configure.in: Explicitly set SET_MAKE to empty, to disable
2979 MAKE=make even when no make already exists. Fix bug #3823.
2981 2004-02-22 Paul D. Smith <psmith@gnu.org>
2983 * maintMakefile: Perl script to clean up all non-CVS files. Use
2984 it on all the subdirectories for the cvs-clean target.
2986 * main.c (decode_switches): Require non-empty strings for all our
2987 string command-line options. Fixes Debian bug # 164165.
2989 * configure.in: Check for stdarg.h and varargs.h.
2990 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2991 for printing messages.
2992 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2997 A number of patches for OS/2 support from Andreas Buening
2998 <andreas.buening@nexgo.de>:
3000 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3001 disable the SIGCHLD handler.
3002 (reap_children) [OS/2]: Remove special handling of job_rfd.
3003 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3004 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3005 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3006 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3007 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3010 2004-02-21 Paul D. Smith <psmith@gnu.org>
3012 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3013 <mail@kristov.de> reports that if process_begin() fails we don't
3014 handle the error condition correctly in all cases.
3015 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3016 to have a newline on the message.
3018 * job.c (construct_command_argv_internal): Add "test" to UNIX
3019 sh_cmds[]. Fixes Savannah bug # 7606.
3021 2004-02-04 Paul D. Smith <psmith@gnu.org>
3023 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3024 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3025 Hartmut Becker <Hartmut.Becker@hp.com>.
3027 2004-01-21 Paul D. Smith <psmith@gnu.org>
3029 * job.c (load_too_high): Implement an algorithm to control the
3030 "thundering herd" problem when using -l to control job creation
3031 via the load average. The system only recomputes the load once a
3032 second but we can start many jobs in a second. To solve this we
3033 keep track of the number of jobs started in the last second and
3034 apply a weight to try to guess what a correct load would be.
3035 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3036 Also fixes bug #4693.
3037 (reap_children): Decrease the job count for this second.
3038 (start_job_command): Increase the job count for this second.
3040 * read.c (conditional_line): Expand the text after ifn?def before
3041 checking to see if it's a single word. Fixes bug #7257.
3043 2004-01-09 Paul D. Smith <psmith@gnu.org>
3045 * file.c (print_file): Recurse to print all targets in
3046 double-colon rules. Fixes bug #4518, reported (with patch) by
3047 Andrew Chatham <chatham@google.com>.
3049 2004-01-07 Paul D. Smith <psmith@gnu.org>
3051 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3052 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3053 AC_FUNC_SETVBUF_REVERSED.
3055 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3056 (MAKE Variable): Fix Savannah bug #4898.
3058 * job.c (construct_command_argv_internal): Add "!" to the list of
3059 shell escape chars. POSIX sh allows it to appear before a
3060 command, to negate the exit code. Fixes bug #6404.
3062 * implicit.c (pattern_search): When matching an implicit rule,
3063 remember which dependencies have the ignore_mtime flag set.
3064 Original fix provided in Savannah patch #2349, by Benoit
3065 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3067 2003-11-22 Paul D. Smith <psmith@gnu.org>
3069 * README.W32.template (Outputs): Clarification on -j with
3070 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3073 2003-11-02 Paul D. Smith <psmith@gnu.org>
3075 * function.c (func_if): Strip all the trailing whitespace from the
3076 condition, then don't expand it. Fixed bug # 5798.
3078 * expand.c (recursively_expand_for_file): If we're expanding a
3079 variable with no file context, then use the variable's context.
3082 2003-10-21 Paul D. Smith <psmith@gnu.org>
3084 * main.c (log_working_directory): Add newlines to printf()s.
3086 * README.cvs: Add a note to ignore warnings during autoreconf.
3088 * maintMakefile (po_repo): Set a new URL for PO file updates.
3089 (get-config/config.guess get-config/config.sub): Get these files
3090 from the Savannah config project instead of ftp.gnu.org.
3092 2003-10-05 Paul Eggert <eggert@twinsun.com>
3094 * main.c (main): Avoid potential subscript error if environ has
3097 2003-08-22 Paul D. Smith <psmith@gnu.org>
3099 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3100 systems which don't yet implement the C89 standard :-/.
3102 2003-07-18 Paul D. Smith <psmith@gnu.org>
3104 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3105 [WINDOWS32]: Initialize hash.
3107 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3109 * dir.c (read_dirstream): Provide a workaround for broken versions of
3110 the MinGW dirent structure.
3112 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3114 * w32/include/dirent.h: Add __MINGW32__ filter.
3116 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3118 * make.h: Add global declaration of *make_host.
3119 * main.c (print_usage): Remove local declaration of *make_host.
3120 (print_version): Display "This program built for ..." after Copyright
3123 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3125 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3126 execution of "makeinfo --html make.texi".
3128 2003-04-30 Paul D. Smith <psmith@gnu.org>
3130 * build.template: Make some changes to maybe allow this script to
3131 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3133 * README.OS2.template: New file for OS/2 support. Original
3134 contributed by Andreas Buening.
3135 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3138 2003-04-19 Paul D. Smith <psmith@gnu.org>
3140 Fix bug #1405: allow a target to match multiple pattern-specific
3143 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3144 variable.c, where they've always belonged.
3145 * rule.h: Move the prototypes and struct pattern_var as well.
3146 * variable.c (initialize_file_variables): Invoke
3147 lookup_pattern_var() in a loop, until no more matches are found.
3148 If a match is found, create a new variable set for the target's
3149 pattern variables. Then merge the contents of each matching
3150 pattern variable set into the target's pattern variable set.
3151 (lookup_pattern_var): Change this function to be usable
3152 in a loop. It takes a starting position: if NULL, start at the
3153 beginning; if non-NULL, start with the pattern variable after that
3154 position, and return the next matching pattern.
3155 (create_pattern_var): Create a unique instance of
3156 pattern-specific variables for every definition in the makefile.
3157 Don't combine the same pattern together. This allows us to
3158 process the variable handling properly even when the same pattern
3159 is used multiple times.
3160 (parse_variable_definition): New function: break out the parsing
3161 of a variable definition line from try_variable_definition.
3162 (try_variable_definition): Call parse_variable_definition to
3164 (print_variable_data_base): Print out pattern-specific variables.
3165 * variable.h (struct variable): Remember when a variable is
3166 conditional. Also remember its flavor.
3167 (struct pattern_var): Instead of keeping a variable set, we just
3168 keep a single variable for each pattern.
3169 * read.c (record_target_var): Each pattern variable contains only a
3170 single variable, not a set, so create it properly.
3171 * doc/make.texi (Pattern-specific): Document the new behavior.
3173 2003-04-17 Paul D. Smith <psmith@gnu.org>
3175 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3176 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3177 file/directory naming rules for VMS so I can't tell whether this
3180 2003-04-09 Paul D. Smith <psmith@gnu.org>
3182 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3183 DOS-style pathnames: backslash separators and drive specifiers.
3185 2003-03-28 Paul D. Smith <psmith@gnu.org>
3187 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3188 the intermediate flag on all targets. Fixes bug #2515.
3190 2003-03-24 Paul D. Smith <psmith@gnu.org>
3192 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3193 Upgrade to autoconf 2.57 and automake 1.7.3.
3195 * job.c: More OS/2 changes from Andreas Buening.
3197 * file.c (print_file): Fix variable initialization.
3200 * remake.c (notice_finished_file):
3202 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3203 some calls (like readdir()) return NULL in valid situations
3204 without resetting errno. Fixes bug #2846.
3206 2003-02-25 Paul D. Smith <psmith@gnu.org>
3208 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3210 * job.c (_is_unixy_shell) [OS/2]: New function.
3211 Set default shell to /bin/sh.
3212 (reap_children): Close the job_rfd pipe here since we don't use a
3214 (set_child_handler_action_flags): define this to empty on OS/2.
3215 (start_job_command): Close the jobserver pipe and use
3216 child_execute_job() instead of fork/exec.
3217 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3218 rather than exec'ing, then reconfigure stdin/stdout.
3219 (exec_command): Rewrite to use spawn instead of exec. Return the
3222 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3223 in DOS. Handle the TEMP environment variable as in DOS. Don't
3224 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3225 use -j in DOS mode. Use child_execute_job() instead of
3228 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3231 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3232 prototypes that return values.
3234 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3236 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3237 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3239 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3242 2003-02-24 Paul D. Smith <psmith@gnu.org>
3244 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3245 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3246 (child_execute_job) [VMS]: Handle error status properly.
3247 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3249 * function.c (func_shell): Use EINTRLOOP() while reading from the
3250 subshell pipe (Fixes bug #2502).
3251 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3253 * main.c (main): Ditto.
3255 2003-01-30 Paul D. Smith <psmith@gnu.org>
3257 * read.c (eval): eval() was not fully reentrant, because the
3258 collapsed buffer was static. Change it to be an automatic
3259 variable so that eval() can be invoked recursively.
3261 (eval): Apply patch # 1022: fix memory reference error on long
3262 target-specific variable lines.
3263 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3265 * function.c (check_numeric): Combine the is_numeric() function
3266 into this function, since it's only called from one place.
3267 Constify this function. Have it print the incorrect string in the
3268 error message. Fixes bug #2407.
3269 (strip_whitespace): Constify.
3270 (func_if): Constify.
3271 * expand.c (expand_argument): Constify.
3273 2003-01-29 Paul D. Smith <psmith@gnu.org>
3275 Fix bug # 2169, also reported by other people on various systems.
3277 * make.h: Some systems, such as Solaris and PTX, do not fully
3278 implement POSIX-compliant SA_RESTART functionality; important
3279 system calls like stat() and readdir() can still fail with EINTR
3280 even if SA_RESTART has been set on the signal handler. So,
3281 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3282 EINTR for system calls which return -1 or 0 (NULL), respectively,
3284 Also, remove the old atomic_stat()/atomic_readdir() and
3285 HAVE_BROKEN_RESTART handling.
3287 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3289 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3290 * remake.c (touch_file): Ditto.
3292 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3293 * read.c (construct_include_path): Ditto.
3294 * remake.c (name_mtime): Ditto.
3295 * vpath.c (selective_vpath_search): Ditto.
3296 * dir.c (find_directory): Ditto.
3297 (local_stat): Ditto.
3298 (find_directory): Use ENULLLOOP() to wrap opendir().
3299 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3301 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3302 atomic_readdir() handling.
3304 2003-01-22 Paul D. Smith <psmith@gnu.org>
3306 * function.c (func_call): Fix Bug #1744. If we're inside a
3307 recursive invocation of $(call ...), mask any of the outer
3308 invocation's arguments that aren't used by this one, so that this
3309 invocation doesn't "inherit" them accidentally.
3311 2002-12-05 Paul D. Smith <psmith@gnu.org>
3313 * function.c (subst_expand): Valery Khamenia reported a
3314 pathological performance hit when doing substitutions on very
3315 large values with lots of words: turns out we were invoking
3316 strlen() a ridiculous number of times. Instead of having each
3317 call to sindex() call strlen() again, keep track of how much of
3318 the text we've seen and pass the length to sindex().
3320 2002-11-19 Paul D. Smith <psmith@gnu.org>
3322 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3325 2002-11-16 Paul D. Smith <psmith@gnu.org>
3327 * NMakefile.template (OBJS): Add hash.c object file.
3328 * SMakefile.template (srcs): Ditto.
3329 * Makefile.ami (objs): Ditto.
3330 * build_w32.bat: Ditto.
3332 * Makefile.DOS.template: Remove extra dependencies.
3334 2002-10-25 Paul D. Smith <psmith@gnu.org>
3336 * expand.c (install_variable_buffer): New function. Install a new
3337 variable_buffer context and return the previous one.
3338 (restore_variable_buffer): New function. Free the current
3339 variable_buffer context and put a previously saved one back.
3340 * variable.h: Prototypes for {install,restore}_variable_buffer.
3341 * function.c (func_eval): Push a new variable_buffer context
3342 before we eval, then restore the old one when we're done.
3345 * read.c (install_conditionals): New function. Install a new
3346 conditional context and return the previous one.
3347 (restore_conditionals): New function. Free the current
3348 conditional context and put a previously saved one back.
3349 (eval): Use the {install,restore}_conditionals for "include"
3351 (eval_buffer): Use {install,restore}_conditionals to preserve the
3352 present conditional state before we evaluate the buffer.
3355 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3357 (Recursion): Add a variable index entry for CURDIR.
3359 * README.cvs: Update to appropriate versions.
3360 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3361 don't need to copy loadavg.c: automake is smart enough to create
3362 it for me. Still have a bug in automake related to ansi2knr tho.
3364 2002-10-14 Paul D. Smith <psmith@gnu.org>
3366 * remake.c (notice_finished_file): Only touch targets if they have
3367 at least one command (as per POSIX). Resolve Bug #1418.
3369 * *.c: Convert to using ANSI C-style function definitions.
3370 * Makefile.am: Enable the ansi2knr feature of automake.
3371 * configure.in: ditto.
3373 2002-10-13 Paul D. Smith <psmith@gnu.org>
3375 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3376 for automatic variable values like $^, etc. In the case of very
3377 large lists of prerequisites this causes problems. Instead reuse
3378 a static buffer (resizeable) for each variable.
3380 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3381 target-specific variable definitions. Check for it and set an
3383 (record_target_var): Set the export field to v_export if the
3384 "exported" flag is set.
3385 * doc/make.texi (Target-specific): Document the ability to use
3388 * doc/make.texi: Change the name of the section on automatic
3389 variables from "Automatic" to "Automatic Variables". Added text
3390 clarifying the scope of automatic variables.
3392 2002-10-04 Paul D. Smith <psmith@gnu.org>
3394 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3396 (record_files): Ditto.
3398 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3399 the search for the '=' to only within the enclosing parens.
3401 2002-10-03 Paul D. Smith <psmith@gnu.org>
3403 Version 3.80 released.
3405 * dir.c: Change hash functions to use K&R function definition style.
3406 * function.c: Ditto.
3408 * variable.c: Ditto.
3410 Update to automake 1.7.
3412 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3413 (pdf): Remove this target as automake now provides one.
3415 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3417 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3419 * makefile.com: Updates for GNU make 3.80.
3420 * makefile.vms: Ditto.
3422 2002-09-23 Paul D. Smith <psmith@gnu.org>
3424 * read.c (enum make_word_type): Remove w_comment.
3425 (get_next_mword): Don't treat comment characters as special; where
3426 this function is used we will never see a comment (it's stripped
3427 before we get here) and treating comments specially means that
3428 targets like "foo\#bar" aren't handled properly.
3430 2002-09-18 Paul D. Smith <psmith@gnu.org>
3432 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3434 * read.c (eval): Expansion of arguments to export/unexport was
3435 ignoring all arguments after the first one. Change the algorithm
3436 to expand the whole line once, then parse the results.
3438 2002-09-17 Paul D. Smith <psmith@gnu.org>
3440 Fix Bug #940 (plus another bug I found while looking at this):
3442 * read.c (record_target_var): enter_file() will add a new entry if
3443 it's a double-colon target: we don't want to do that in this
3444 situation. Invoke lookup_file() and only enter_file() if it does
3445 not already exist. If the file we get back is a double-colon then
3446 add this variable to the "root" double-colon target.
3448 * variable.c (initialize_file_variables): If this file is a
3449 double-colon target but is not the "root" target, then initialize
3450 the root and make the root's variable list the parent of our
3453 2002-09-13 Paul D. Smith <psmith@gnu.org>
3455 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3457 * hash.c (round_up_2): Get rid of a warning.
3459 2002-09-12 Paul D. Smith <psmith@gnu.org>
3461 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3462 so it doesn't complain about getloadavg.c.
3464 * commands.c (set_file_variables): Make sure we always alloca() at
3465 least 1 character for the value of $? (for '\0').
3467 2002-09-11 Paul D. Smith <psmith@gnu.org>
3469 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3470 macro to use RESULT instead of the incorrect _RESULT_.
3472 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3473 and atomic_readdir(). We need to #include dirent.h to get this to
3475 * misc.c (atomic_readdir): Fix typos.
3477 2002-09-10 Paul D. Smith <psmith@gnu.org>
3479 * read.c (eval): Expand variable lists given to export and
3480 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3481 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3483 * doc/make.texi (Variables/Recursion): Document this.
3484 (Conditional Syntax): And here.
3486 2002-09-09 Paul D. Smith <psmith@gnu.org>
3488 * configure.in: Check for memmove().
3490 2002-09-07 Paul D. Smith <psmith@gnu.org>
3492 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3493 Michael Sterrett <msterret@coat.com> reports that while it has
3494 SA_RESTART, it does not work properly.
3496 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3497 that invokes stat() and loops to do it again if it returns EINTR.
3498 (atomic_readdir): Ditto, with readdir().
3500 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3501 and readdir() to atomic_stat() and atomic_readdir().
3503 2002-09-04 Paul D. Smith <psmith@gnu.org>
3505 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3506 reports that GNU make sometimes doesn't recognize that targets can
3507 be made, when directories can be created as prerequisites. He
3508 reports that changing the order of predicates in the DEP->changed
3509 flag test so that lookup_file() is always performed, solves this
3512 2002-08-08 Paul D. Smith <psmith@gnu.org>
3514 * configure.in: Require a newer version of gettext.
3516 * misc.c (perror_with_name): Translate the format string (for
3517 right-to-left language support).
3518 (pfatal_with_name): Ditto.
3520 * main.c: Create a static array of strings to store the usage
3521 text. This is done to facilitate translations.
3522 (struct command_switch): Remove argdesc and description fields.
3523 (switches): Remove values for obsolete fields.
3524 (print_usage): Print each element of the usage array.
3526 * hash.c: Change function definitions to be K&R style.
3528 2002-08-02 Paul D. Smith <psmith@gnu.org>
3530 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3531 this one because it's too hard to get right. We'll look at it for
3533 * main.c (main): Don't create the .TARGETS variable.
3534 * variable.c (handle_special_var): Don't handle .TARGETS.
3536 2002-08-01 Paul D. Smith <psmith@gnu.org>
3538 * main.c (switches): Add a new option, -B (--always-make). If
3539 specified, make will rebuild all targets that it encounters even
3540 if they don't appear to be out of date.
3541 (always_make_flag): New flag.
3542 * make.h: Extern always_make_flag.
3543 * remake.c (update_file_1): Check always_make_flag; if it's set we
3544 will always rebuild any target we can, even if none of its
3545 prerequisites are newer.
3548 * doc/make.texi (Shell Function): Make it clear that make
3549 variables marked as "export" are not passed to instances of the
3552 Add new introspection variable .VARIABLES and .TARGETS.
3554 * variable.c (handle_special_var): New function. If the variable
3555 reference passed in is "special" (.VARIABLES or .TARGETS),
3556 calculate the new value if necessary. .VARIABLES is handled here:
3557 walk through the hash of defined variables and construct a value
3558 which is a list of the names. .TARGETS is handled by
3559 build_target_list().
3560 (lookup_variable): Invoke handle_special_var().
3561 * file.c (build_target_list): Walk through the hask of known files
3562 and construct a list of the names of all the ones marked as
3564 * main.c (main): Initialize them to empty (and as simple variables).
3565 * doc/make.texi (Special Variables): Document them.
3566 * NEWS: Mention them.
3568 * variable.h (struct variable): Add a new flag "exportable" which
3569 is true if the variable name is valid for export.
3570 * variable.c (define_variable_in_set): Set "exportable" when a new
3571 variable is defined.
3572 (target_environment): Use the "exportable" flag instead of
3573 re-checking the name here... an efficiency improvement.
3575 2002-07-31 Paul D. Smith <psmith@gnu.org>
3577 * config.h-vms.template: Updates to build on VMS. Thanks to
3578 Brian_Benning@aksteel.com for helping verify the build.
3579 * makefile.com: Build the new hash.c file.
3580 * hash.h: Use strcpmi(), not stricmp(), in the
3581 HAVE_CASE_INSENSITIVE_FS case.
3583 2002-07-30 Paul D. Smith <psmith@gnu.org>
3585 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3586 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3587 Reported by <Brian_Benning@aksteel.com>.
3589 2002-07-10 Paul D. Smith <psmith@gnu.org>
3591 * variable.c (pop_variable_scope): Remove variable made unused by
3592 new hash infrastructure.
3593 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3594 comparisons as well as name comparisons.
3595 * variable.h: Add a prototype for new hash_init_function_table().
3596 * file.c (lookup_file): Remove variables made unused by new hash
3598 * dir.c (directory_contents_hash_2): Missing return of hash value.
3599 (dir_contents_file_exists_p): Remove variables made unused by new
3600 hash infrastructure.
3603 Installed Greg McGary's integration of the hash functions from the
3604 GNU id-utils package:
3606 2002-07-10 Greg McGary <greg@mcgary.org>
3608 * scripts/functions/filter-out: Add literals to to the
3609 pattern space in order to add complexity, and trigger
3610 use of an internal hash table. Fix documentation strings.
3611 * scripts/targets/INTERMEDIATE: Reverse order of files
3612 passed to expected `rm' command.
3614 2002-07-10 Greg McGary <greg@mcgary.org>
3616 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3617 * hash.c: New file, taken from id-utils.
3618 * hash.h: New file, taken from id-utils.
3620 * make.h (HASH, HASHI): Remove macros.
3621 (find_char_unquote): Change arglist in decl.
3622 (hash_init_directories): New function decl.
3623 * variable.h (hash.h): New #include.
3624 (MAKELEVEL_NAME, MAKELEVEL_LENGTH): New constants.
3625 * filedef.h (hash.h): New #include.
3626 (struct file) [next]: Remove member.
3627 (file_hash_enter): Remove function decl.
3628 (init_hash_files): New function decl.
3630 * ar.c (ar_name): Delay call to strlen until needed.

3673 (struct a_pattern): New struct.
3674 (func_filter_filterout): Pass through patterns noting boundaries
3675 and '%', if present. Note a_word length. Use a hash table if
3676 arglists are large enough to justify cost.
3677 (function_table_init): Renamed from function_table.

3685 (uniquize_deps): Use hash table to efficiently identify duplicates.
3686 (find_char_unquote): Accept two char-constant stop chars, rather
3687 than a string constant, avoiding zillions of calls to strchr.
3688 Tighten inner search loops to test only for desired delimiters.

3706 2002-07-10 Paul D. Smith <psmith@gnu.org>
3708 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3709 prerequisite list. A real SysV make will expand the entire
3710 prerequisites list _twice_: we don't do that as it's a big
3711 backward-compatibility problem. We only replace those specific
3714 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3715 references left in the list of prerequisites. Check for .POSIX as
3716 we record targets, so we can disable non-POSIX behavior while
3717 reading makefiles as well as running them.
3718 (eval): Check the prerequisite list to see if we have anything
3719 that looks like a SysV prerequisite variable reference.
3721 2002-07-09 Paul D. Smith <psmith@gnu.org>
3723 * doc/make.texi (Prerequisite Types): Add a new section describing
3724 order-only prerequisites.
3726 * read.c (uniquize_deps): If we have the same file as both a
3727 normal and order-only prereq, get rid of the order-only prereq,
3728 since the normal one supersedes it.
3730 2002-07-08 Paul D. Smith <psmith@gnu.org>
3732 * AUTHORS: Added Greg McGary to the AUTHORS file.
3733 * NEWS: Blurbed order-only prerequisites.
3734 * file.c (print_file): Show order-only deps properly when printing
3737 * maintMakefile: Add "update" targets for wget'ing the latest
3738 versions of various external files. Taken from Makefile.maint in
3741 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3742 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3744 2002-07-07 Paul D. Smith <psmith@gnu.org>
3746 * po/*.po: Remove. We'll use wget to retrieve them at release
3749 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3750 rather than a shell you get an exception. Make sure we look up
3751 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3753 * remake.c (notice_finished_file): Fix handling of -t flag.
3754 Patch provided by Henning Makholm <henning@makholm.net>.
3756 * implicit.c (pattern_search): Some systems apparently run short
3757 of stack space, and using alloca() in this function caused an
3758 overrun. I modified it to use xmalloc() on the two variables
3759 which seemed like they might get large. Fixes Bug #476.
3761 * main.c (print_version): Update copyright notice to conform with
3763 (print_usage): Update help output.
3765 * function.c (func_eval): Create a new make function, $(eval
3766 ...). Expand the arguments, put them into a buffer, then invoke
3767 eval_buffer() on the resulting string.
3768 (func_quote): Create a new function, $(quote VARNAME). Inserts
3769 the value of the variable VARNAME without expanding it any
3772 * read.c (struct ebuffer): Change the linebuffer structure to an
3773 "eval buffer", which can be either a file or a buffer.
3774 (eval_makefile): Move the code in the old read_makefile() which
3775 located a makefile into here: create a struct ebuffer with that
3776 information. Have it invoke the new function eval() with that
3778 (eval_buffer): Create a new function that creates a struct ebuffer
3779 that holds a string buffer instead of a file. Have it invoke
3780 eval() with that ebuffer.
3781 (eval): New function that contains the guts of the old
3782 read_makefile() function: this function parses makefiles. Obtains
3783 data to parse from the provided ebuffer. Some modifications to
3784 make the flow of the function cleaner and clearer. Still could
3785 use some work here...
3786 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3787 contents of the define/endef variable from the ebuffer.
3788 (readstring): Read the next line from a string-style ebuffer.
3789 (readline): Read the next line from an ebuffer. If it's a string
3790 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3793 * dep.h (eval_buffer): Prototype eval_buffer();
3795 * variable.c (do_variable_definition): Make sure that all
3796 non-target-specific variables are registered in the global set.
3797 If we're invoked from an $(eval ...) we might be inside a $(call
3798 ...) or other function which has pushed a variable scope; we still
3799 want to define our variables from evaluated makefile code in the
3802 2002-07-03 Greg McGary <greg@mcgary.org>
3804 * dep.h (struct dep) [ignore_mtime]: New member.
3805 [changed]: convert to a bitfield.
3806 * implicit.c (pattern_search): Zero ignore_mtime.
3807 * main.c (main, handle_non_switch_argument): Likewise.
3808 * rule.c (convert_suffix_rule): Likewise.
3809 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3810 (read_makefile): Parse '|' in prerequisite list.
3811 (uniquize_deps): Consider ignore_mtime when comparing deps.
3812 * remake.c (update_file_1, check_dep): Don't force remake for
3813 dependencies that have d->ignore_mtime.
3814 * commands.c (FILE_LIST_SEPARATOR): New constant.
3815 (set_file_variables): Don't include a
3816 prerequisite in $+, $^ or $? if d->ignore_mtime.
3819 2002-06-18 Paul D. Smith <psmith@gnu.org>
3821 * make.texinfo: Updates for next revision. New date/rev/etc.
3822 Recreate all Info menus. Change license on the manual to the GNU
3823 Free Documentation License. A number of typos.
3824 (Variables Simplify): Don't use "-" before it's defined.
3825 (Automatic Prerequisites): Rewrite the target example to work
3826 properly if the compile fails. Remove incorrect comments about
3827 how "set -e" behaves.
3828 (Text Functions): Move the "word", "wordlist", "words", and
3829 "firstword" functions here, from "File Name Functions".
3830 * make-stds.texi: Update from latest GNU version.
3831 * fdl.texi: (created) Import the latest GNU version.
3833 2002-06-06 Paul D. Smith <psmith@gnu.org>
3835 * variable.c (do_variable_definition): New function: extract the
3836 part of try_variable_definition() that actually sets the value
3837 into a separate function.
3838 (try_variable_definition): Call do_variable_definition() after
3839 parsing the variable definition string.
3840 (define_variable_in_set): Make the name argument const.
3842 * variable.h (enum variable_flavor): Make public.
3843 (do_variable_definition): Create prototype.
3845 * read.c (read_all_makefiles): Create a new built-in variable,
3847 (read_makefile): Add each makefile read in to this variable value.
3849 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3851 * Makefile.DOS.template: Tweak according to changes in the
3852 distribution. Add back the dependencies of *.o files.
3854 * configh.dos.template: Synchronize with config.h.in.
3856 2002-05-09 Paul D. Smith <psmith@gnu.org>
3858 * file.c (file_timestamp_now): Use K&R function declaration.
3860 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3861 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3862 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3863 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3864 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3865 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3866 nlist.n_name is a pointer rather than an array.
3868 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3869 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3870 * configure.in: Use it instead of the old version.
3872 * main.c (main): Prefer setvbuf() to setlinebuf().
3874 2002-05-08 Paul D. Smith <psmith@gnu.org>
3876 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3877 (loadavg_LDADD): Ditto.
3879 2002-04-29 Paul D. Smith <psmith@gnu.org>
3881 * expand.c (recursively_expand_for_file): Rename
3882 recursively_expand() to recursively_expand_for_file() and provide
3883 an extra argument, struct file. If the argument is provided, set
3884 the variable scope to that of the file before expanding.
3885 * variable.h (recursively_expand): Make this a macro that invokes
3886 recursively_expand_for_file() with a NULL file pointer.
3887 * variable.c (target_environment): Call the renamed function and
3888 provide the current file context.
3889 Fixes Debian bug #144306.
3891 2002-04-28 Paul D. Smith <psmith@gnu.org>
3893 Allow $(call ...) user-defined variables to be self-referencing
3894 without throwing an error. Allows implementation of transitive
3895 closures, among other possibly useful things.
3896 Requested by: Philip Guenther <guenther@sendmail.com>
3898 * variable.h (struct variable): Add a new field: exp_count, and
3899 new macros to hold its size and maximum value.
3900 (warn_undefined): Make this a macro.
3901 * variable.c (define_variable_in_set): Initialize it.
3902 * expand.c (recursively_expand): If we detect recursive expansion
3903 of a variable, check the exp_count field. If it's greater than 0
3904 allow the recursion and decrement the count.
3905 (warn_undefined): Remove this (now a macro in variable.h).
3906 * function.c (func_call): Before we expand the user-defined
3907 function, modify its exp_count field to contain the maximum
3908 number of recursive calls we'll allow. After the call, reset it
3911 2002-04-21 Paul D. Smith <psmith@gnu.org>
3913 Modified to use latest autoconf (2.53), automake (1.6.1), and
3914 gettext (0.11.1). We're using gettext's new "external" support,
3915 to avoid including libintl source with GNU make.
3917 * README.cvs: New file. Explain how to build GNU make from CVS.
3919 * configure.in: Modify checking for the system glob library.
3920 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3921 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3922 etc. will manage it correctly). Set an automake conditional
3923 USE_LOCAL_GLOB to decide whether to compile the glob library.
3925 * getloadavg.c (main): Include make.h in the "TEST" program to
3928 * Makefile.am: Remove special rules for loadavg. Replace them
3929 with Automake capabilities for building extra programs.
3931 * signame.c: This file does nothing if the system provide
3932 strsignal(). If not, it implements strsignal(). If the system
3933 doesn't define sys_siglist, then we make our own; otherwise we use
3935 * signame.h: Removed.
3937 * main.c (main): No need to invoke signame_init(). Update copyright.
3939 * ABOUT-NLS: Removed.
3940 * gettext.c: Removed.
3941 * gettext.h: Get a simplified copy from the gettext package.
3943 * i18n/*.po: Moved to po/.
3946 * config/*: Created. Contains package configuration helper files.
3947 * config.guess, config.sub: Moved to config directory.
3949 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3950 Rework to use new-style autoconf features. Use the "external"
3951 mode for gettext. Make the build.sh config file conditional on
3952 whether build.sh.in exists, to avoid autoconf errors.
3953 * acinclude.m4: Removed almost all macros as being obsolete.
3954 Rewrote remaining macros to use AC_DEFINE.
3955 * acconfig.h: Removed.
3957 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3958 conditional to handle customs support. Remove special handling
3961 2002-04-20 Paul D. Smith <psmith@gnu.org>
3963 * function.c (func_call): Don't mark the argument variables $1,
3964 etc. as recursive. They've already been fully expanded so
3965 there's no need to do it again, and doing so strips escaped $'s.
3966 Reported by Sebastian Glita <glseba@yahoo.com>.
3968 * remake.c (notice_finished_file): Walk through double-colon
3969 entries via the prev field, not the next field!
3970 Reported by Greg McGary <greg@mcgary.org>.
3972 * main.c (main): If the user specifies -q and asks for a specific
3973 target which is a makefile, we got an assert. In that case it
3974 turns out we should continue normally instead.
3976 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3978 * i18n/he.po: Installed a new translation.
3980 2002-01-07 Paul D. Smith <psmith@gnu.org>
3982 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3984 2001-12-04 Paul D. Smith <psmith@gnu.org>
3986 * i18n/ja.po: Installed an updated translation.
3988 2001-09-06 Paul Eggert <eggert@twinsun.com>
3990 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3991 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3993 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3995 (main): Get rid of any avoidable limit on stack size.
3997 2001-09-04 Paul D. Smith <psmith@gnu.org>
3999 * i18n/da.po: Installed an updated translation.
4001 2001-08-03 Paul D. Smith <psmith@gnu.org>
4003 * i18n/fr.po: Installed an updated translation.
4004 Resolves Debian bug #106720.
4006 2001-06-13 Paul D. Smith <psmith@gnu.org>
4008 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4011 2001-06-11 Paul D. Smith <psmith@gnu.org>
4013 * i18n/ko.po: Installed a new translation.
4015 2001-05-06 Paul D. Smith <psmith@gnu.org>
4017 Modify the EINTR handling.
4019 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4020 the way in which we manage the file descriptor/signal handler race
4021 trap to be more efficient.
4023 2001-05-06 Paul Eggert <eggert@twinsun.com>
4025 Restart almost all system calls that are interrupted, instead
4026 of worrying about EINTR. The lone exception is the read() for
4029 * configure.in (HAVE_SA_RESTART): New macro.
4030 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4031 * main.c (main): Use SA_RESTART instead of the old,
4032 nonstandard SA_INTERRUPT.
4034 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4035 * main.c (bsd_signal): New function or macro,
4036 if the implementation doesn't supply it.
4037 (The bsd_signal function will be in POSIX 1003.1-200x.)
4038 (HANDLESIG): Remove.
4039 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4041 * make.h (EINTR_SET): Remove.
4042 (SA_RESTART): New macro.
4044 * arscan.c (ar_member_touch): Don't worry about EINTR.
4045 * function.c (func_shell): Likewise.
4046 * job.c (reap_children, free_child, new_job): Likewise.
4047 * main.c (main): Likewise.
4048 * remake.c (touch_file, name_mtime): Likewise.
4050 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4051 if fstat failed with errno!=EINTR, the error was ignored.
4053 * job.c (set_child_handler_action_flags): New function.
4054 (new_job): Use it to temporarily clear the SIGCHLD action flags
4055 while reading the token.
4057 2001-05-02 Paul D. Smith <psmith@gnu.org>
4059 * job.c (start_job_command): Don't add define/endef per-line flags
4060 to the top-level flags setting.
4062 2001-04-03 Paul D. Smith <psmith@gnu.org>
4064 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4065 bit on error, so check for odd return values, not non-0 return
4067 (VMS_get_member_info): Calculate the timezone differences correctly.
4068 Reported by John Fowler <jfowler@nyx.net>.
4071 2001-03-14 Paul D. Smith <psmith@gnu.org>
4073 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4074 value before invoking define_variable().
4075 Reported by John Fowler <jfowler@nyx.net>.
4077 2001-02-07 Paul D. Smith <psmith@gnu.org>
4079 * read.c (record_target_var): If we reset the variable due to a
4080 command-line variable setting overriding it, turn off the "append"
4083 2001-01-17 Paul D. Smith <psmith@gnu.org>
4085 * variable.c (lookup_variable) [VMS]: When getting values from the
4086 environment, allocate enough space for the _value_ plus escapes,
4087 not enough space for the name plus escapes :-/.
4088 Reported by John Fowler <jfowler@nyx.net>.
4090 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4091 warnings that make generates, so it doesn't look like an error.
4092 Reported by Karl Berry <karl@gnu.org>.
4095 Fix for PR/2020: Rework appended target-specific variables. I'm
4096 fairly confident this algorithm is finally correct.
4098 * expand.c (allocated_variable_append): Rewrite. Instead of
4099 expanding each appended variable then adding all the expanded
4100 strings together, we append all the unexpanded values going up
4101 through the variable set contexts, then expand the final result.
4102 This behaves just like non-target-specific appended variable
4103 values, while the old way didn't in various corner cases.
4104 (variable_append): New function: recursively append the unexpanded
4105 value of a variable, walking from the outermost variable scope to
4107 * variable.c (lookup_variable): Remove the code that looked up the
4108 variable set list if the found variable was "append". We don't
4110 (lookup_variable_in_set): Make this non-static so we can use it
4112 (try_variable_definition): Use lookup_variable_in_set() rather
4113 than faking out current_variable_set_list by hand (cleanup).
4114 * variable.h: Add a prototype for the now non-static
4115 lookup_variable_in_set().
4117 2000-11-17 Paul D. Smith <psmith@gnu.org>
4119 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4120 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4121 before throwing a fit.
4123 2000-11-17 Paul D. Smith <psmith@gnu.org>
4125 * read.c (readline): CRLF calculations had a hole, if you hit the
4126 buffer grow scenario just right. Reworked the algorithm to avoid
4127 the need for len or lastlen at all. Problem description with
4128 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4130 2000-10-24 Paul D. Smith <psmith@gnu.org>
4132 * gettext.c (SWAP): Declare this with the prototype, otherwise
4133 some systems don't work (non-32-bit? Reported for Cray T3E).
4134 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4136 2000-10-05 Paul D. Smith <psmith@gnu.org>
4138 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4139 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4141 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4143 2000-09-22 Paul D. Smith <psmith@gnu.org>
4145 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4146 parts of the real gettext.h here, and we expect to really include
4147 the real gettext.h later. If we keep this #define, it's ignored.
4149 2000-09-21 Paul D. Smith <psmith@gnu.org>
4151 * main.c (log_working_directory): Rework the text to use complete
4152 sentences, to make life simpler for the translators.
4154 2000-08-29 Paul D. Smith <psmith@gnu.org>
4156 * file.c (remove_intermediates): Print a debug message before we
4157 remove intermediate files, so the user (if she uses -d) knows
4160 2000-08-21 Paul D. Smith <psmith@gnu.org>
4162 * variable.c (try_variable_definition): Change how we handle
4163 target-specific append variable defns: instead of just setting the
4164 value, expand it as an append _but_ only within the current
4165 target's context. Otherwise we lose all but the last value if the
4166 variable is appended more than once within the current target
4167 context. Fixes PR/1831.
4169 2000-08-16 Paul D. Smith <psmith@gnu.org>
4171 * function.c (func_shell): Nul-terminate the buffer before
4172 printing an exec error message (just in case it's not!).
4173 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4175 2000-07-25 Paul D. Smith <psmith@gnu.org>
4177 * job.c (construct_command_argv_internal): Add "~" to the list of
4178 sh_chars[] which disallow optimizing out the shell call.
4180 2000-07-23 Paul Eggert <eggert@twinsun.com>
4182 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4183 supersedes --disable-nsec-timestamps.
4184 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4185 * README: Remove --disable-nsec-timestamps.
4187 * filedef.h (struct file.low_resolution_time): New member.
4188 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4189 * remake.c (update_file_1):
4190 Avoid spurious rebuilds due to low resolution time stamps,
4191 generalizing the earlier code that applied only to archive members.
4192 (f_mtime): Archive members always have low resolution time stamps.
4194 * configure.in: Remove --disable-nsec-timestamps, as this has
4195 been superseded by .LOW_RESOLUTION_TIME.
4197 2000-07-23 Paul Eggert <eggert@twinsun.com>
4199 * configure.in (enable_nsec_timestamps): Renamed from
4200 make_cv_nsec_timestamps, since enable/disable options
4201 shouldn't be cached.
4203 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4204 and Paul Eggert <eggert@twinsun.com>
4206 * file.c (file_timestamp_now):
4207 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4208 so that clock_gettime is not linked unless needed.
4210 * filedef.h (FILE_TIMESTAMP_HI_RES):
4211 Remove definition; "configure" now does this.
4213 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4214 to before high resolution file timestamp check,
4215 since that check now uses uintmax_t.
4216 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4217 high resolution file timestamps.
4218 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4219 so that we don't link in clock_gettime unnecessarily.
4221 2000-07-17 Paul D. Smith <psmith@gnu.org>
4223 * i18n/ja.po: New version of the translation file.
4225 2000-07-07 Paul D. Smith <psmith@gnu.org>
4227 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4228 the offset calculation.
4229 (name_mtime): Replace EINTR test with EINTR_SET macro.
4231 2000-07-07 Paul Eggert <eggert@twinsun.com>
4235 * remake.c (update_file_1):
4236 Avoid spurious rebuilds of archive members due to their
4237 timestamp resolution being only one second.
4238 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4239 the clock's resolution being lower than file timestamps'.
4240 When warning about future timestamps, report only the discrepancy,
4241 not the absolute value of the timestamp and the current time.
4243 * file.c (file_timestamp_now): New arg RESOLUTION.
4244 * filedef.h (file_timestamp_now): Likewise.
4245 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4247 2000-07-05 Paul D. Smith <psmith@gnu.org>
4249 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4250 to listp. Fixes PR/1793.
4252 2000-06-26 Paul Eggert <eggert@twinsun.com>
4254 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4256 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4258 * remake.c (f_mtime): Remove unused var memtime.
4260 2000-06-25 Martin Buchholz <martin@xemacs.org>
4262 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4263 Ran spell-check on make.texinfo.
4265 2000-06-23 Paul D. Smith <psmith@gnu.org>
4267 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4268 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4269 * make.h: Define these macros.
4271 * Version 3.79.1 released.
4273 * configure.in: Add a new option, --disable-nsec-timestamps, to
4274 avoid using sub-second timestamps on systems that support it. It
4275 can lead to problems, e.g. if your makefile relies on "cp -p".
4276 * README.template: Document the issue with "cp -p".
4278 * config.guess, config.sub: Updated.
