24 2011-08-29 Paul Smith <psmith@gnu.org>
26 * expand.c (variable_expand_string): Always allocate a new buffer
27 for a string we're expanding. The string we're working on can get
28 freed while we work on it (for example if it's the value of a
29 variable which modifies itself using an eval operation).
30 See Savannah patch #7534 for the original report by Lubomir Rintel.
32 2011-06-12 Paul Smith <psmith@gnu.org>
34 * read.c (parse_file_seq): Move the check for empty members out of

50 2011-05-07 Eli Zaretskii <eliz@gnu.org>
52 * job.c (construct_command_argv_internal): Don't assume shellflags
53 is always non-NULL. Escape-protect characters special to the

90 (do_variable_definition): Handle f_shell variables: expand the
91 value, then send it to the shell and store the result.
92 (parse_variable_definition): Parse "!=" shell assignments.
93 * read.c (get_next_mword): Treat "!=" as a varassign word.

101 * strcache.c (various): Increase performance based on comments
102 from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>. Stop looking for
103 a buffer when we find the first one that fits, not the best fit.
104 If there is not enough free space in a buffer move it to a
105 separate list so we don't have to walk it again.

529 * doc/make.texi (Undefine Directive): Describe the new directive.
531 * NEWS: Add a note about the new directive.
533 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
535 * implicit.c (pattern_search): Initialize file variables only
536 if we need to parse a rule that requires the second expansion.
538 2009-10-03 Paul Smith <psmith@gnu.org>
540 * make.h: Include <alloca.h> even on systems where __GNUC__ is
541 defined. Not sure why it was done the other way.
542 Requested by David Boyce <dsb@boyski.com>.
544 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
546 * dep.h (dep): Add the DONTCARE bitfield.
548 * filedef.h (file):Add the NO_DIAG bitfield.
550 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
551 not struct file (a file can be a dependency of many targets,
552 some don't care, some do).
554 * remake.c (update_goal_chain): Propagate DONTCARE from struct
555 dep to struct file before updating the goal and restore it
556 afterwards.
557 (update_file): Don't prune the dependency graph if this target
558 has failed but the diagnostics hasn't been issued.
559 (complain): Scan the file's dependency graph to find the file
560 that caused the failure.
561 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
562 whether to print diagnostics.
564 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
566 2009-09-28 Paul Smith <psmith@gnu.org>
568 * doc/make.texi (Pattern Intro): Move the match algorithm
569 discussion into the "Pattern Match" node.
570 (Pattern Match): Expand on the pattern rule matching algorithm.
572 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
574 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
575 much of the command line on a single pass.
577 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
579 * varible.c (create_pattern_var): Insert variables into the
580 PATTERN_VARS list in the shortest patterns first order.
582 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
583 used to sort the rules.
584 (stemlen_compare): Compare two tryrule elements.
585 (pattern_search): Sort the rules so that they are in the shortest
586 stem first order.
588 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
590 * doc/make.texi (Pattern-specific Variable Values): Describe the
591 new pattern-specific variables application order.
592 (Introduction to Pattern Rules): Describe the new pattern rules
593 search order.
595 * NEWS: Add a note about the new behavior.
597 2009-09-27 Paul Smith <psmith@gnu.org>
599 * doc/make.texi (Double-Colon): Mention that pattern rules with
600 double-colons have a different meaning. Savannah bug #27497.
602 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
604 * configh.dos.template: Remove unconditional definition of
605 SYS_SIGLIST_DECLARED.
606 Include <sys/version.h> because ports of GCC 4.3.0 and later no
607 longer include it, so macros like __DJGPP_MINOR__ are no longer
608 defined automatically.
610 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
611 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
612 instead of using the hardcoded ones.
613 (SUBDIRS): doc subdir added.
614 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
615 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
616 create html formated docs. texi2html may not be ported to DOS.
617 (make.info, make.dvi, make.ps, make.html): Make targets depend on
618 'make.texi'.
619 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
620 -I switch to look in ./ instead of ./doc.
621 (html): Target depend on html-recursive instead of make_1.html.
622 (make_1.html): Removed.
623 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
624 (all-recursive): Allow for more than one subdir in the build
625 process.
626 (mostlyclean-recursive, clean-recursive, distclean-recursive)
627 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
628 (tags-recursive): Allow for more than one subdir in the build
629 process.
630 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
631 targets. Enter into doc/ to produce the targets.
632 (all-am): $(INFO_DEPS) replaced by info.
634 2009-09-26 Paul Smith <psmith@gnu.org>
636 * read.c (record_files): Use free_ns() to free struct nameseq.
637 (eval): Ditto.
639 * rule.c (freerule): Use free_dep_chain().
641 * read.c (record_files): Free FILENAMES chain for implicit rules.
642 (eval): Static pattern targets go into the string cache.
644 * function.c (string_glob): Free NAME in the nameseq chain.
646 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
648 * implicit.c (pattern_search): Terminate early if we haven't
649 found any rules to try (performance improvement).
651 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
653 * implicit.c (pattern_search): Merge three parallel arrays,
654 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
655 of struct TRYRULE. In the old version the latter two arrays
656 had insufficient length.
658 2009-09-24 Paul Smith <psmith@gnu.org>
660 * implicit.c (pattern_search): Add back support for order-only
661 prerequisites for secondary expansion implicit rules, that were
662 accidentally dropped. If we find a "|", enable order-only mode
663 and set IGNORE_MTIME on all deps that are seen afterward.
664 (pattern_search): Fix memory leaks: for intermediate files where
665 we've already set the file variable and pattern variable sets, be
666 sure to either save or free them as appropriate.
668 2009-09-23 Paul Smith <psmith@gnu.org>
670 Rework the way secondary expansion is stored, for efficiency.
671 This changes secondary expansion so that ONLY WHEN we know we have
672 a possibility of needing secondary expansion, do we defer the
673 secondary expansion. This means more parsing the deps but we use
674 a lot less memory (due to the strcache). Also, this fixes
675 Savannah bug #18622.
677 * read.c (eval): Don't parse the dep string here anymore.
678 (record_files): Take the dep argument as an unparsed string. If
679 secondary expansion is enabled AND the prereq string has a '$' in
680 it, then set NEED_2ND_EXPANSION and keep the entire string.
681 Otherwise, parse the dep string here to construct the dep list
682 with the names in the strcache.
684 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
685 duplicate the name string (others are in the strcache).
687 * implicit.c: Remove struct idep and free_idep_chain(): unused.
688 (struct patdeps): New structure to store prereq information.
689 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
690 which prerequisites need expansion, and expand only those.
692 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
693 and enter_prereqs(). split_prereqs() takes a fully-expanded string
694 and splits it into a DEP list, handling order-only prereqs.
695 (enter_prereqs): This function enters a list of DEPs into the file
696 database. If there's a stem defined, expand any pattern chars.
697 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
698 set. Use the above functions.
699 (snap_deps): Only perform second expansion on prereqs that need it,
700 as defined by the NEED_2ND_EXPANSION flag.
701 (print_prereqs): New function to print the prereqs
702 (print_file): Call print_prereqs() rather than print inline.
704 * hash.h (STRING_COMPARE): Take advantage of strcache() by
705 comparing pointers.
706 (STRING_N_COMPARE): Ditto.
707 (ISTRING_COMPARE): Ditto.
709 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
710 (parse_file_seq): Return void*
711 * read.c (parse_file_seq): Return void*.
712 (eval): Invoke macroized version of parse_file_seq()
713 * default.c (set_default_suffixes): Ditto.
714 * file.c (split_prereqs): Ditto.
715 * function.c (string_glob): Ditto.
716 * main.c (main): Ditto.
717 * rule.c (install_pattern_rule): Ditto.
719 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
721 2009-09-16 Paul Smith <psmith@gnu.org>
723 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
724 convert to macros.
725 * dep.h: Create alloc_dep() / free_dep() macros.
727 * implicit.c (pattern_search): Take advantage of the new
728 parse_file_seq() to add the directory prefix to each prereq.
730 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
731 all. Avoid reversing chains. Support adding prefixes.
732 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
733 cached/non-cached results.
734 (eval): Remove multi_glob() & invoke new parse_file_seq().
735 * rule.c (install_pattern_rule): Ditto.
736 * main.c (main): Ditto.
737 * implicit.c (pattern_search): Ditto.
738 * function.c (string_glob): Ditto.
739 * file.c (parse_prereqs): Ditto.
740 * default.c (set_default_suffixes): Ditto.
742 * variable.c (parse_variable_definition): Don't run off the end of
743 the string if it ends in whitespace (found with valgrind).
745 * commands.c (set_file_variables): Keep space for all targets in
746 $? if -B is given (found with valgrind).
748 2009-09-15 Paul Smith <psmith@gnu.org>
750 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
751 (xcalloc): Add new function.
752 * make.h: New declarations.
754 * ar.c (ar_glob_match): New calling method for concat().
755 * main.c (main): Ditto.
756 (decode_env_switches): Ditto.
757 * read.c (eval_makefile): Ditto.
758 (tilde_expand): Ditto.
759 (parse_file_seq): Ditto.
760 * variable.c (target_environment): Ditto.
761 (sync_Path_environment): Ditto.
763 * ar.c (ar_glob_match): Use xcalloc().
764 * dir.c (file_impossible): Ditto.
765 * file.c (enter_file): Ditto.
766 * job.c (new_job): Ditto.
767 * read.c (parse_file_seq): Ditto.
768 * vmsfunctions.c (opendir): Ditto.
770 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
772 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
773 inside the loop that looks up environment for PATH.
775 2009-08-31 Eli Zaretskii <eliz@gnu.org>
777 * function.c (windows32_openpipe): Update envp after calling
778 sync_Path_environment.
780 2009-08-02 Paul Smith <psmith@gnu.org>
782 * remake.c (notice_finished_file): Ensure file->cmds is not null
783 before looping through them. Fixes Savannah bug #21824.
785 * doc/make.texi (Wildcard Examples): Clarify when objects is
786 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
787 (Include): Clarify the behavior of -include.
788 Fixes Savannah bug #18963.
790 2009-08-01 Paul Smith <psmith@gnu.org>
792 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
793 etc. come on the command line. Fixes Savannah bug #27093.
795 * expand.c (expand_argument): If the argument is large enough use
796 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
798 * variable.c (do_variable_definition): Avoid using alloca() to
799 hold values, which can be large. Fixes Savannah bug #23960.
801 * job.c (new_job): Use memmove() instead of strcpy() since both
802 pointers are in the same memory block. Fixes Savannah bug #27148.
803 Patch by Petr Machata.
805 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
807 * job.c (construct_command_argv_internal): Add "ulimit" and
808 "unset" to the sh_cmds for Unixy shells.
810 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
812 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
813 that set make_cv_sys_gnu_glob, so they are also correctly set
814 when the cache has been populated before.
816 2009-07-04 Eli Zaretskii <eliz@gnu.org>
818 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
819 exist, as realpath(3) does where it's supported.
821 2006-07-04 Eli Zaretskii <eliz@gnu.org>
823 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
824 (abspath): Support systems that define HAVE_DOS_PATHS (have
825 drive letters in their file names). Use IS_PATHSEP instead of a
826 literal '/' comparison. Fixes Savannah bug #26886.
828 2009-06-14 Paul Smith <psmith@gnu.org>
830 * remake.c (update_file_1): Remember the original file we marked
831 as updating, so we can clear that flag again. If we find a target
832 via vpath, FILE might change.
833 (check_dep): Ditto. Fixes Savannah bug #13529.
834 Patch by Reid Madsen <reid.madsen@tek.com>.
836 2009-06-13 Paul Smith <psmith@gnu.org>
838 * doc/make.texi (MAKEFILES Variable): Be explicit that files
839 included by MAKEFILES cannot give default goals.
840 * read.c (eval): If set_default is not set, pass the no-default-goal
841 value when we read included makefiles. Fixes Savannah bug #13401.
843 * ar.c (ar_name): Ensure that targets with empty parens aren't
844 considered archive member references: archive members must have a
845 non-empty "member" string. Fixes Savannah bug #18435.
847 * function.c (string_glob): Rely on multi_glob() to determine
848 whether files exist or not. Remove call to file_exists_p() which
849 is not always correct. Fixes Savannah bug #21231.
850 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
851 then only files that really exist will be returned.
852 * dep.h: Add new argument to multi_glob().
853 * rule.c (install_pattern_rule): Ditto.
854 * read.c (eval): Ditto.
855 * main.c (main): Ditto.
856 * implicit.c (pattern_search): Ditto.
857 * file.c (parse_prereqs): Ditto.
858 * default.c (set_default_suffixes): Ditto.
860 2009-06-09 Paul Smith <psmith@gnu.org>
862 * commands.c (set_file_variables): If always_make_flag is set,
863 always add the prereq to $?. Fixes Savannah bug #17825.
865 * remake.c (update_file_1): When rebuilding deps of FILE, also try
866 to rebuild the deps of all the also_make targets for that file.
867 Fixes Savannah bug #19108.
869 * implicit.c (pattern_search): Undo test for is_target, added by
870 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
871 Rule Search Algorithm". Fixes Savannah bug #17752.
873 * main.c (clean_jobserver): Clear the jobserver_fds options and
874 set job_slots to the default when we clean up.
875 (define_makeflags): Return the new MAKEFLAGS value.
876 (main): Reset MAKEFLAGS in the environment when we re-exec.
877 Fixes Savannah bug #18124.
879 2009-06-08 Paul Smith <psmith@gnu.org>
881 * read.c (eval): Collapse continuations post-semicolon on target-
882 specific variables. Fixes Savannah bug #17521.
884 2009-06-07 Paul Smith <psmith@gnu.org>
886 * job.c (reap_children): For older systems without waitpid() (are
887 there any of these left?) run wait(2) inside EINTRLOOP to handle
888 EINTR errors. Fixes Savannah bug #16401.
890 * (various): Debug message cleanup. Fixes Savannah bug #16469.
892 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
894 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
895 not the end, to catch second expansion $(eval ...) defining new
896 target/prereq relationships during snap_deps.
897 Fixes Savannah bug #24622.
899 * read.c (record_files): The second-expansion "f->updating" hack
900 was not completely correct: if assumed that the target with
901 commands always had prerequisites; if one didn't then the ordering
902 was messed up. Fixed for now to use f->updating to decide whether
903 to preserve the last element in the deps list... but this whole
904 area of constructing and reversing the deps list is too confusing
905 and needs to be reworked. Fixes Savannah bug #21198.
907 2009-06-06 Paul Smith <psmith@gnu.org>
909 * hash.c (hash_insert): Remove useless test for NULL.
910 Fixes Savannah bug #21823.
912 * make.h: Move SET_STACK_SIZE determination to make.h.
913 * main.c (main): New global variable, STACK_LIMIT, holds the
914 original stack limit when make was started.
915 * job.c (start_job_command): Reset the stack limit, if we changed it.
916 Fixes Savannah bug #22010.
918 * remake.c (check_dep): Only set the target's state to not-started
919 if it's not already running. Found this while testing -j10 builds
920 of glibc: various targets were being rebuilt multiple times.
921 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
922 bug #15919.
924 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
925 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
926 Bugzilla bug 10246.
928 2009-06-04 Paul Smith <psmith@gnu.org>
930 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
932 * maintMakefile: Modify access of config and gnulib Savannah
933 modules to use GIT instead of CVS.
935 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
936 Fixes Savannah bug #24655.
938 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
939 this can happen during some invocations of $(eval ...) for example.
940 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
942 2009-06-02 Paul Smith <psmith@gnu.org>
944 * configure.in: Check for fileno()
945 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
946 for the makefile file so invocations of $(shell ...) don't inherit it.
947 Fixes Savannah bug #24277.
949 2009-06-01 Paul Smith <psmith@gnu.org>
951 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
952 expansion was handled incorrectly. Rework the default goal
953 handling to save the variable only. Remove default_goal_file and
954 default_goal_name.
955 * read.c (eval): Check default_goal_var, not default_goal_name.
956 * read.c (record_target_var): Don't check default_goal_file here.
958 2009-05-31 Paul Smith <psmith@gnu.org>
960 * main.c (main): Expand the .DEFAULT_GOAL variable before using
961 it, and if the multi_glob() returns nothing (say it expanded to
962 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
964 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
965 $(and ..) to the reference. Fixes Savannah bug #25694.
967 * make.1: Be clear that some recipes will be executed even with -n.
968 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
970 * doc/make.texi (Override Directive): Make more clear how
971 overrides and appends interact.
972 Elucidates part of Savannah bug #26207.
974 * read.c (record_target_var): Don't reset the origin on
975 target-specific variables; try_variable_definition() will handle
976 this correctly. Fixes Savannah bug #26207.
978 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
979 Fixes Savannah bug #25712.
981 * implicit.c (pattern_search): Keep a pointer to the beginning of
982 the filename and save that instead of the constructed pointer.
983 Fixes Savannah bug #26593.
984 Patch by Mark Seaborn <mrs@mythic-beasts.com>
986 2009-05-30 Paul Smith <psmith@gnu.org>
988 * doc/make.texi (Multi-Line): Add a description of the new abilities
989 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
990 "command sequence" vs. "recipe" syntax.
991 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
992 after a define, to create variables with those flavors.
994 2009-05-25 Paul Smith <psmith@gnu.org>
996 Reworked the parser for variable assignments to allow multiple
997 modifiers, and in any order. Also allows variable and
998 prerequisites to be modifier names ('export', 'private', etc.)
1000 * NEWS: Add notes about user-visible changes.
1002 * read.c (struct vmodifiers): Remember what modifiers were seen.
1003 (parse_var_assignment): New function to parse variable assignments.
1004 (eval): Call the new function. Handle variable assignments earlier.
1006 * variable.c (parse_variable_definition): Only parse; don't create var.
1007 (assign_variable_definition): Call parse, then create the var.
1009 2009-05-24 Paul Smith <psmith@gnu.org>
1011 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1012 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1014 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1016 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1017 Fixes Savannah bug #25412.
1019 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1020 prototype for xmalloc.
1021 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1022 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1023 Loop over an array of extensions, instead of duplicating the same
1024 code inline. Use SearchPath followed by CreateFile, instead of
1025 the obsolete OpenFile. Fixes Savannah bug #17277.
1026 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1027 to `find_file'. Fixes Savannah bug #25662.
1029 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1031 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1032 Fixes Savannah bug #20495.
1034 2009-02-28 Ralf Wildenhues <address@hidden>
1036 * doc/make.texi (Instead of Execution): Document interaction of
1037 -t with phony targets.
1039 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1041 Introduce a new keyword "private" which applies to target-specific
1042 variables and prevents their values from being inherited.
1044 * variable.h (struct variable): Add private_var flag to each variable.
1045 Add a flag to specify which list entry switches to the parent target.

1128 HAVE_DECL_SYS_SIGLIST.
1130 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1131 build does not use child_execute_job.
1133 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1134 export the SHELL environment variable to the child.
1136 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1160 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1161 a more complex value than a simple shell: if it's not a default

1164 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1166 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1167 pathnames, with const strings.
1168 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1173 * make.h: Add a prototype for w32_kill() (change suggested by

1200 2007-09-10 Paul Smith <psmith@gnu.org>
1202 * commands.c (print_commands): Don't print an extra line in the
1203 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1205 * read.c (construct_include_path): Add the full string to the cache; we
1206 were chopping the last char.
1208 * NEWS: Announce the .RECIPEPREFIX special variable.
1209 * variable.c (lookup_special_var): Rename from handle_special_var().
1210 (lookup_variable): Call the new name.

1215 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1216 * main.c (main): Create the .RECIPEPREFIX special variable.
1217 * read.c (eval): Remove the cmd_prefix characters from the command
1218 scripts here, so they're not stored in the commands array at all,
1219 rather than waiting and stripping them out during command construction.
1220 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1222 2007-08-15 Paul Smith <psmith@gnu.org>
1224 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1225 file has had the section info removed, so add some to make.texi
1226 before we include it.
1228 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1230 * remake.c (check_dep): Reset the target state for intermediate
1231 files. They might have been considered before but not updated

1250 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1251 Fixes Savannah bug #20452.
1253 2007-07-04 Paul Smith <psmith@gnu.org>

1267 "Expansion of a deferred"
1268 Fixes Savannah bug #20018.
1270 * expand.c (variable_expand_for_file): Preserve the value of

1274 2007-05-11 Paul Smith <psmith@gnu.org>
1276 * job.c (new_job): Add debug info to specify where make found the
1277 command script it is running to build a target.
1278 Fixes Savannah bug #18617.
1280 * default.c (default_suffixes,default_suffix_rules,default_variables):
1281 Add support for Objective C. Fixes Savannah bug #16389.
1282 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1284 * function.c (func_lastword): Initialize p.
1286 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1287 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1288 Dave Korn <dave.korn@artimi.com>
1290 2007-05-08 Paul Smith <psmith@gnu.org>
1292 Fix Savannah bug #19656:
1294 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1296 * make.h: Change all case-insensitive string compares to use
1297 strcasecmp() (from POSIX). If we don't have that but do have one
1298 of the others, define strcasecmp to be one of those instead. If
1299 we don't have any, declare a prototype for our own version.
1301 * misc.c (strcasecmp): Use this if we can't find any native
1302 case-insensitive string comparison function.
1303 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1304 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1305 strcmpi().
1306 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1307 strcasecmp() instead of stricmp().
1308 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1309 instead of strcmpi().
1310 * acinclude.m4: Remove the strcasecmp() check from here.
1312 2007-03-21 Paul Smith <psmith@gnu.org>
1314 * configure.in: Don't turn on case-insensitive file system support
1315 if --disable-... is given. Fixes Savannah bug #19348.
1317 2007-03-19 Paul Smith <psmith@gnu.org>
1319 * ALL: Use the strcache for all file name strings, or other
1320 strings which we will never free. The goal is to save memory by
1321 avoiding duplicate copies of strings. However, at the moment this
1322 doesn't save much memory in most situations: due to secondary
1323 expansion we actually save prerequisite lists twice (once before
1324 the secondary expansion, and then again after it's been parsed
1325 into individual file names in the dep list). We will resolve this
1326 in a future change, by doing the parsing up-front for targets
1327 where secondary expansion is not set.
1329 Moving things into the strcache also allows us to use const
1330 pointers in many more places.
1332 2007-01-03 Paul Smith <psmith@gnu.org>
1334 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1335 the function, not just the first. Fixes Savannah bug #18680.
1337 2006-11-18 Paul Smith <psmith@gnu.org>
1339 * strcache.c (strcache_add_len): Don't allocate a new buffer
1340 unless the string is not already nil-terminated. Technically this
1341 is a violation of the standard, since we may be passed an array
1342 that is not long enough to test one past. However, in make this
1343 is never true since we only use nil-terminated strings or
1344 sub-strings thereof.
1346 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1348 * main.c: New global cmd_prefix, defaults to '\t'.
1349 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1350 of '\t'.
1352 * dir.c: Constified.
1353 (dir_contents_file_exists_p): Check for an error return from
1354 readdir(), just in case.
1356 * commands.c: Constified.
1357 * default.c: Constified.
1358 * expand.c: Constified.
1359 * function.c: Partial constification.
1360 * variable.c: Partial constification.
1361 * vmsify.c: Constification. Hard to test this but I hope I didn't
1362 screw it up!
1363 * vpath.c: Partial constification.
1364 * w32/pathstuff.c: Partial constification.
1366 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1368 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1369 backslashes and drive letters as absolute.
1371 2006-10-22 Paul Smith <psmith@gnu.org>
1373 * main.c (struct command_switch): Use const and void*.
1375 2006-10-21 Paul Smith <psmith@gnu.org>
1377 * ar.c: Constified.
1378 * arscan.c: Constified.
1380 2006-09-30 Paul Smith <psmith@gnu.org>
1382 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1383 point to lastword since the example was updated.
1384 Fixes Savannah bug #16304.
1385 (Secondary Expansion): Correct example description.
1386 Fixes Savannah bug #16468.
1387 (Makefile Contents): Clarify that comments cannot appear within
1388 variable references or function calls.
1389 Fixes Savannah bug #16577.
1390 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1391 Fixes Savannah bug #17701.
1392 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1393 (Prerequisite Types): Added an example of using order-only
1394 prerequisites. Fixes Savannah bug #17880.
1395 (Rule Syntax): "lise" -> "list"
1396 (Multiple Rules): ... -> @dots{}
1397 (Splitting Lines): ditto.
1399 * remake.c (update_file_1): Prereqs that don't exist should be
1400 considered changed, for the purposes of $?.
1401 Fixes Savannah bug #16051.
1403 * make.1: Remove extraneous "+".
1404 Fixes Savannah bug #16652.
1406 2006-09-06 Paul D. Smith <psmith@gnu.org>

1413 $PATH_SEPARATOR.
1415 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1416 Normally, it is defined in config.h.
1418 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1419 well.
1421 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1422 sh_chars_sh for Windows platforms that emulate Unix.
1424 2006-05-07 Paul D. Smith <psmith@gnu.org>

1450 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1451 inner-scope variables don't mask outer-scope variables.
1453 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1454 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1455 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1456 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1457 values from memory allocation functions: they return void* and so
1458 don't need to be cast. Also remove (char *) casts of arguments to
1459 xrealloc().
1461 * configure.in: Remove checks for memcpy/memmove/strchr.
1463 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

1469 * variable.c, vpath.c: Ditto.
1471 * make.h (EXIT_FAILURE): Should be 1, not 0.
1473 2006-04-06 Paul D. Smith <psmith@gnu.org>

1499 version.texi now.
1501 2006-03-26 Paul D. Smith <psmith@gnu.org>
1503 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1504 support from automake, as described in the Texinfo manual.
1506 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1508 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1509 with lastslash, since the latter points to filename, not to
1510 target.
1511 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1512 Declare and define sh_chars_sh[].
1514 2006-03-23 Paul D. Smith <psmith@gnu.org>
1516 * configure.in: Look for build.sh.in in $srcdir so it will be
1517 built for remote configurations as well.

1520 Fixes Savannah bug #16166.
1522 * misc.c (log_access): Takes a const char *.

1558 (free_dep_chain): Use free_dep.
1559 * read.c (record_files): Store stem in the dependency line.
1560 * file.c (expand_deps): Use stem stored in the dependency line. Use
1561 free_dep_chain instead of free_ns_chain.
1562 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1563 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1564 * main.c (main, handle_non_switch_argument): Ditto.
1565 * remake.c (check_dep): Ditto.
1566 * rule.c (convert_suffix_rule, freerule): Ditto.
1568 2006-03-14 Paul D. Smith <psmith@gnu.org>
1570 * expand.c (variable_append): Instead of appending everything then
1571 expanding the result, we expand (or not, if it's simple) each part
1572 as we add it.
1573 (allocated_variable_append): Don't expand the final result.
1574 Fixes Savannah bug #15913.
1576 2006-03-09 Paul Smith <psmith@gnu.org>
1578 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1579 listed non-existent files as changed. Turns out there's a bug in
1580 the Linux kernel builds which means that this change causes
1581 everything to rebuild every time. We will re-introduce this fix
1582 in the next release, to give them time to fix their build system.
1583 Fixes Savannah bug #16002.
1584 Introduces Savannah bug #16051.
1586 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1587 we *don't* find UNIX "/".
1588 Reported by David Ergo <david.ergo@alterface.com>
1590 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1592 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1593 locator function find_and_set_default_shell if SHELL came from the
1594 command line.
1596 2006-02-20 Paul D. Smith <psmith@gnu.org>
1598 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1599 to be null; don't core in that case.
1601 2006-02-19 Paul D. Smith <psmith@gnu.org>
1603 * commands.c (set_file_variables): Realloc, not malloc, the static
1604 string values to avoid memory leaks.
1606 * expand.c (recursively_expand_for_file): Only set reading_file to
1607 an initialized value.
1609 * implicit.c (pattern_search): We need to make a copy of the stem
1610 if we get it from an intermediate dep, since those get freed.
1612 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1613 begin with ".".
1614 (enter_file) [VMS]: Ditto.
1615 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1617 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1619 * job.c (construct_command_argv_internal): Fix last change.
1621 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1622 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1623 the calls to _beginthreadex.
1625 * expand.c (recursively_expand_for_file): Initialize `save' to
1626 prevent compiler warnings.
1628 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1630 * job.c (construct_command_argv_internal): Don't create a temporary
1631 script/batch file if we are under -n. Call _setmode to switch the
1632 script file stream to text mode.
1634 2006-02-17 Paul D. Smith <psmith@gnu.org>
1636 * variable.c (merge_variable_set_lists): Don't try to merge the
1637 global_setlist. Not only is this useless, but it can lead to
1638 circularities in the linked list, if global_setlist->next in one
1639 list gets set to point to another list which also ends in
1640 global_setlist.
1641 Fixes Savannah bug #15757.
1643 2006-02-15 Paul D. Smith <psmith@gnu.org>
1645 Fix for Savannah bug #106.
1647 * expand.c (expanding_var): Keep track of which variable we're
1648 expanding. If no variable is being expanded, it's the same as
1649 reading_file.
1650 * make.h (expanding_var): Declare it.
1651 * expand.c (recursively_expand_for_file): Set expanding_var to the
1652 current variable we're expanding, unless there's no file info in
1653 it (could happen if it comes from the command line or a default
1654 variable). Restore it before we exit.
1655 * expand.c (variable_expand_string): Use the expanding_var file
1656 info instead of the reading_file info.
1657 * function.c (check_numeric): Ditto.
1658 (func_word): Ditto.
1659 (func_wordlist): Ditto.
1660 (func_error): Ditto.
1661 (expand_builtin_function): Ditto.
1662 (handle_function): Ditto.
1664 2006-02-14 Paul D. Smith <psmith@gnu.org>
1666 * read.c (eval): Even if the included filenames expands to the
1667 empty string we still need to free the allocated buffer.
1669 * implicit.c (pattern_search): If we allocated a variable set for
1670 an impossible file, free it.
1671 * variable.c (free_variable_set): New function.
1672 * variable.h: Declare it.
1674 * read.c (read_all_makefiles): Makefile names are kept in the
1675 strcache, so there's never any need to alloc/free them.
1676 (eval): Ditto.
1678 * main.c (main): Add "archives" to the .FEATURES variable if
1679 archive support is enabled.
1680 * doc/make.texi (Special Variables): Document it.
1682 2006-02-13 Paul D. Smith <psmith@gnu.org>
1684 * implicit.c (pattern_search): Add checking for DOS pathnames to
1685 the pattern rule target LASTSLASH manipulation.
1686 Fixes Savannah bug #11183.
1688 2006-02-11 Paul D. Smith <psmith@gnu.org>
1690 * (ALL FILES): Updated copyright and license notices.
1692 2006-02-10 Paul D. Smith <psmith@gnu.org>
1694 A new internal capability: the string cache is a read-only cache
1695 of strings, with a hash table interface for fast lookup. Nothing
1696 in the cache will ever be freed, so there's no need for reference
1697 counting, etc. This is the beginning of a full solution for
1698 Savannah bug #15182, but for now we only store makefile names here.
1700 * strcache.c: New file. Implement a read-only string cache.
1701 * make.h: Add prototypes for new functions.
1702 * main.c (initialize_global_hash_tables): Initialize the string cache.
1703 (print_data_base): Print string cache stats.
1704 * read.c (eval_makefile): Use the string cache to store makefile
1705 names. Rewrite the string allocation to be sure we free everything.
1707 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1709 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1710 directory time stamp didn't change, except on FAT filesystems.
1711 Suggested by J. David Bryan <jdbryan@acm.org>.
1713 2006-02-09 Paul D. Smith <psmith@gnu.org>
1715 * function.c (func_or): Implement a short-circuiting OR function.
1716 (func_and): Implement a short-circuiting AND function.
1717 (function_table_init): Update the table with the new functions.
1718 * doc/make.texi (Conditional Functions): Changed the "if" section
1719 to one on general conditional functions. Added documentation for
1720 $(and ...) and $(or ...) functions.
1721 * NEWS: Note new $(and ...) and $(or ...) functions.
1723 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1725 * job.h (struct child): Add the dontcare bitfield.
1726 * job.c (new_job): Cache dontcare flag.
1727 * job.c (reap_children): Use cached dontcare flag instead of the
1728 one in struct file. Fixes Savannah bug #15641.
1730 2006-02-06 Paul D. Smith <psmith@gnu.org>
1732 * vpath.c (selective_vpath_search): If the file we find has a
1733 timestamp from -o or -W, use that instead of the real time.
1734 * remake.c (f_mtime): If the mtime is a special token from -o or
1735 -W, don't overwrite it with the real mtime.
1736 Fixes Savannah bug #15341.
1738 Updates from Markus Mauhart <qwe123@chello.at>:
1740 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1741 (process_signal, process_last_err, process_exit_code): Manage
1742 invalid handle values.
1743 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1744 manage invalid handles; remove them.
1745 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1746 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1747 * README.cvs: Updates for building from CVS.
1749 2006-02-05 Paul D. Smith <psmith@gnu.org>
1751 * file.c (enter_file): Keep track of the last double_colon entry,
1752 to avoid walking the list every time we want to add a new one.
1753 Fixes Savannah bug #15533.
1754 * filedef.h (struct file): Add a new LAST pointer.
1756 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1757 the comparison. For 64-bits systems the result of the subtraction
1758 might not fit into an int. Use comparison instead.
1759 Fixes Savannah bug #15534.
1761 * doc/make.texi: Update the chapter on writing commands to reflect
1762 the changes made in 3.81 for backslash/newline and SHELL handling.
1764 2006-02-01 Paul D. Smith <psmith@gnu.org>
1766 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1767 variable st is not used when it's not initialized.
1768 Patch from Eli Zaretskii <eliz@gnu.org>.
1770 2006-01-31 Paul D. Smith <psmith@gnu.org>

1776 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1777 J. Grant <jg@jguk.org>.
1779 * main.c: Update the copyright year in the version output.
1780 * prepare_w32.bat: Remove this file from the distribution.
1782 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1784 * remake.c (update_goal_chain): Set g->changed instead of
1785 incrementing it, as it is only 8-bit wide, and could overflow if
1786 many commands got started in update_file.
1788 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1790 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1791 MAXIMUM_WAIT_OBJECTS.
1792 (process_wait_for_any_private): Change dimension of handles[]
1793 array to MAXIMUM_WAIT_OBJECTS.
1794 (process_used_slots): New function.
1795 (process_register): Don't register more processes than the
1796 available number of slots.
1797 (process_easy): Don't start new processes if all slots are used up.
1799 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1800 are already more children than sub_proc.c can handle, behave as if
1801 the load were too high.
1802 (start_job_command): Fix a typo in error message when process_easy
1803 fails.
1805 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1807 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1808 the shell is not sh.exe.
1810 * job.c (create_batch_file): Renamed from create_batch_filename;
1811 all callers changed. Don't close the temporary file; return its
1812 file descriptor instead. New arg FD allows to return the file
1813 descriptor.
1814 (construct_command_argv_internal): Use _fdopen instead of fopen to
1815 open the batch file.
1817 2006-01-04 Paul D. Smith <psmith@gnu.org>
1819 * readme.vms: Updates for case-insensitive VMS file systems from
1820 Hartmut Becker <Hartmut.Becker@hp.com>.
1821 * dir.c (vms_hash): Ditto.
1822 * vmsify.c (copyto): Ditto.
1823 * vmsfunctions.c (readdir): Ditto.
1825 * make.1: Add a section on the exit codes for make.
1827 * doc/make.texi: A number of minor updates to the documentation.

1832 doesn't exist.
1834 * read.c (eval): Be sure to strip off trailing whitespace from the
1835 prerequisites list properly. Also, initialize all fields in
1836 struct dep when creating a new one.
1838 2005-12-28 Paul D. Smith <psmith@gnu.org>
1840 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1841 disable warnings for MSC.
1842 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1844 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1846 * doc/make.texi (Execution): Add a footnote about changes in
1847 handling of backslash-newline sequences. Mention the differences
1848 on MS-DOS and MS-Windows.
1850 * NEWS: More details about building the MinGW port and a pointer
1851 to README.W32. Fix the section name that describes the new
1852 backward-incompatible processing of backslash-newline sequences.
1853 The special processing of SHELL set to "cmd" is only relevant to
1854 MS-Windows, not MS-DOS.
1856 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1858 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1859 to DWORD, to avoid compiler warnings.
1860 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1861 use %ld in format, to avoid compiler warnings.
1863 * doc/make.texi (Special Targets): Fix a typo.
1864 (Appending): Fix cross-reference to Setting.
1865 (Special Variables, Secondary Expansion, File Name Functions)
1866 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1867 periods after a sentence.
1868 (Execution): Add @: after "e.g.".
1869 (Environment): Fix punctuation.
1870 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1871 (Shell Function, Target-specific): Add @: after "vs."
1873 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1875 * read.c (record_target_var): Initialize variable's export field
1876 with v_default instead of leaving it "initialized" by whatever
1877 garbage happened to be on the heap.
1879 2005-12-12 Paul D. Smith <psmith@gnu.org>
1881 * make.1: Fix some display errors and document all existing options.
1882 Patch by Mike Frysinger <vapier@gentoo.org>.
1884 2005-12-11 Paul D. Smith <psmith@gnu.org>
1886 * implicit.c (pattern_search): If 2nd expansion is not set for
1887 this implicit rule, replace the pattern with the stem directly,
1888 and don't re-expand the variable list. Along with the other
1889 .SECONDEXPANSION changes below, fixes bug #13781.
1891 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1893 * implicit.c (pattern_search): Mark other files that this rule
1894 builds as targets so that they are not treated as intermediates
1895 by the pattern rule search algorithm. Fixes bug #13022.
1897 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1899 * remake.c (notice_finished_file): Propagate the change of
1900 modification time to all the double-colon entries only if
1901 it is the last one to be updated. Fixes bug #14334.
1903 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1905 * function.c (func_flavor): Implement the flavor function which
1906 returns the flavor of a variable.
1907 * doc/make.texi (Functions for Transforming Text): Document it.
1908 * NEWS: Add it to the list of new functions.
1910 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1912 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1913 variable.
1914 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1915 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1917 2005-10-26 Paul Smith <psmith@gnu.org>
1919 * read.c (record_files): Don't set deps flags if there are no deps.
1920 * maintMakefile: We only need to build the templates when we are
1921 creating a distribution, so don't do it for "all".
1923 2005-10-24 Paul D. Smith <psmith@gnu.org>
1925 Make secondary expansion optional: its enabled by declaring the
1926 special target .SECONDEXPANSION.
1928 * NEWS: Update information on second expansion capabilities.
1929 * doc/make.texi (Secondary Expansion): Document the
1930 .SECONDEXPANSION special target and its behavior.

1932 prerequisite list was found in a static pattern rule.
1933 (free_dep_chain): Declare a prototype.
1934 * file.c (parse_prereqs): New function: break out some complexity
1935 from expand_deps().
1936 (expand_deps): If we aren't doing second expansion, replace % with
1937 the stem for static pattern rules. Call the new function.
1938 * filedef.h (parse_prereqs): Declare a prototype.
1939 * implicit.c (pattern_search): Initialize the new staticpattern
1940 field.
1941 * main.c (second_expansion): Declare a global variable to remember
1942 if the special target has been seen. Initialize the new
1943 staticpattern field for prerequisites.
1944 * make.h: Extern for second_expansion.
1945 * misc.c (free_dep_chain): New function: frees a struct dep list.
1946 * read.c (read_all_makefiles): Initialize the staticpattern field.
1947 (eval_makefile): Ditto.
1948 (record_files): Check for the .SECONDEXPANSION target and set
1949 second_expansion global if it's found.
1950 Use the new free_dep_chain() instead of doing it by hand.
1951 Set the staticpattern field for prereqs of static pattern targets.
1953 2005-10-16 Paul D. Smith <psmith@gnu.org>
1955 * main.c (main): Set CURDIR to be a file variable instead of a
1956 default, so that values of CURDIR inherited from the environment
1957 won't override the make value.
1959 2005-09-26 Paul D. Smith <psmith@gnu.org>
1961 * job.c (construct_command_argv_internal): If the line is empty
1962 remember to free the temporary argv strings.
1963 Fixes bug # 14527.
1965 2005-09-16 Paul D. Smith <psmith@gnu.org>
1967 * job.c (start_job_command): The noerror flag is a boolean (single
1968 bit); set it appropriately.
1969 Reported by Mark Eichin <eichin@metacarta.com>
1971 2005-08-29 Paul D. Smith <psmith@gnu.org>
1973 * function.c (func_error): On Windows, output from $(info ...)
1974 seems to come in the wrong order. Try to force it with fflush().
1976 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1978 * read.c (record_files): Move code that sets stem for static
1979 pattern rules out of the if (!two_colon) condition so it is
1980 also executed for two-colon rules. Fixes Savannah bug #13881.
1982 2005-08-08 Paul D. Smith <psmith@gnu.org>
1984 * make.h: Don't test that __STDC__ is non-0. Some compilers
1985 (Windows for example) set it to 0 to denote "ISO C + extensions".
1986 Fixes bug # 13594.
1988 2005-08-07 Paul D. Smith <psmith@gnu.org>
1990 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1991 conditional (slightly different version of a fix from Eli).
1993 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1994 If make is running in parallel without -k and two jobs die in a
1995 row, but not too close to each other, then make will quit without
1996 waiting for the rest of the jobs to die.
1998 * main.c (die): Don't reset err before calling reap_children() the
1999 second time: we still want it to be in the error condition.
2000 * job.c (reap_children): Use a static variable, rather than err,
2001 to control whether or not the error message should be printed.
2003 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2005 * w32/subproc/sub_proc.c: Include signal.h.
2006 (process_pipe_io, process_file_io): Pass a pointer to a local
2007 DWORD variable to GetExitCodeProcess. If the exit code is
2008 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2010 * job.c [WINDOWS32]: Include windows.h.
2011 (main_thread) [WINDOWS32]: New global variable.
2012 (reap_children) [WINDOWS32]: Get the handle for the main thread
2013 and store it in main_thread.
2015 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2016 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2017 doing anything else. When we are done, close the main thread
2018 handle and exit with status 130.
2020 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2022 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2023 pointer to fprintf.
2025 * main.c (find_and_set_default_shell): If found a DOSish shell,
2026 set sh_found and the value of default_shell, and report the
2027 findings in debug mode.
2029 * job.c (construct_command_argv_internal): Check unixy_shell, not
2030 no_default_sh_exe, to decide whether to use Unixy or DOSish
2031 builtin commands.
2033 * README.W32: Update with info about the MinGW build.
2035 * build_w32.bat: Support MinGW.
2037 * w32/subproc/build.bat: Likewise.
2039 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2040 printing DWORD args.
2042 * function.c (windows32_openpipe): Fix format strings for printing
2043 DWORD args.
2045 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2046 'reap_mode'.
2047 (start_job_command): Fix format string for printing the result of
2048 process_easy.
2049 (start_job_command) [WINDOWS32]: Do not define.
2050 (exec_command): Fix format string for printing HANDLE args.
2052 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2053 to avoid compiler warnings.
2054 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2055 (Note: some of these fixes were submitted independently by J. Grant)

2059 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2060 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2061 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2063 2005-07-15 Paul Smith <psmith@gnu.org>
2065 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2066 we don't have a POSIX shell, then revert to the old
2067 backslash-newline behavior (where they are stripped).
2068 Fixes bug #13665.
2070 2005-07-08 Paul D. Smith <psmith@gnu.org>
2072 * config.h.W32.template: Reorder to match the standard config.h,
2073 for easier comparisons.
2074 From J. Grant <jg@jguk.org>
2076 * maintMakefile: Remove .dep_segment before overwriting it, in
2077 case it's not writable or noclobber is set.
2078 * expand.c (variable_expand_string): Cast result of pointer
2079 arithmetic to avoid a warning.
2080 * main.c (switches): Add full-fledged final initializer.
2082 2005-07-06 Paul D. Smith <psmith@gnu.org>
2084 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2085 * signame.c (strsignal): If we found _sys_siglist[] or
2086 __sys_siglist[] use those instead of sys_siglist[].
2087 From Albert Chin <china@thewrittenword.com>
2089 2005-07-04 Paul D. Smith <psmith@gnu.org>
2091 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2092 globfree(); set up to use the GNU versions.
2093 From Martin Zinser <zinser@zinser.no-ip.info>
2095 2005-07-03 Paul D. Smith <psmith@gnu.org>
2097 From J. Grant <jg@jguk.org>:
2099 * README.W32.template: Update the Windows and tested MSVC versions.
2100 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2101 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2102 * build_w32.bat: Ditto.
2103 * w32/subproc/build.bat: Ditto.
2105 2005-06-28 Paul D. Smith <psmith@gnu.org>
2107 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2108 declaration was checked but not present.
2110 2005-06-27 Paul D. Smith <psmith@gnu.org>
2112 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2113 to unsigned long. Fixes Savannah bug #13550.
2115 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2116 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2117 Fixes Savannah bug #13551.
2119 2005-06-26 Paul D. Smith <psmith@gnu.org>
2121 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2122 it if ANSI_STRING is not set.
2124 2005-06-25 Paul D. Smith <psmith@gnu.org>
2126 * read.c (eval): If no filenames are passed to any of the
2127 "include" variants, don't print an error.
2128 * doc/make.texi (Include): Document this.
2129 Fixes Savannah bug #1761.
2131 * job.c (construct_command_argv_internal): Sanitize handling of
2132 backslash/newline pairs according to POSIX: that is, keep the
2133 backslash-newline in the command script, but remove a following
2134 TAB character, if present. In the fast path, make sure that the
2135 behavior matches what the shell would do both inside and outside
2136 of quotes. In the slow path, quote the backslash and put a
2137 literal newline in the string.
2138 Fixes Savannah bug #1332.
2139 * doc/make.texi (Execution): Document the new behavior and give
2140 some examples.
2141 * NEWS: Make a note of the new behavior.
2143 * make.h [WINDOWS32]: #include <direct.h>.
2144 Fixes Savannah bug #13478.
2146 * remake.c (name_mtime): If the stat() of a file fails and the -L
2147 option was given and the file is a symlink, take the best mtime of
2148 the symlink we can get as the mtime of the file and don't fail.
2149 Fixes Savannah bug #13280.
2151 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2152 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2153 inside a variable reference. Make this function static as it's
2154 only used here.
2155 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2156 parsing an unexpanded line looking for semicolons.
2157 Fixes Savannah bug #1454.
2158 * misc.c (remove_comments): Move this to read.c and make it static
2159 as it's only used there. Call find_char_unquote() with new arg.
2160 * make.h: Remove prototypes for find_char_unquote() and
2161 remove_comments() since they're static now.
2163 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2164 its export flag and obtain its value. When we need to re-exec,
2165 increment the value and add it into the environment.
2166 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2167 * NEWS: Mention MAKE_RESTARTS.
2168 * main.c (always_make_set): New variable. Change the -B option to
2169 set this one instead.
2170 (main): When checking makefiles, only set always_make_flag if
2171 always_make_set is set AND the restarts flag is 0. When building
2172 normal targets, set it IFF always_make_set is set.
2173 (main): Avoid infinite recursion with -W, too: only set what-if
2174 files to NEW before we check makefiles if we've never restarted
2175 before. If we have restarted, set what-if files to NEW _after_ we
2176 check makefiles.
2177 Fixes Savannah bug #7566:
2179 2005-06-17 Paul D. Smith <psmith@gnu.org>
2181 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2182 in the prerequisites list.
2184 2005-06-12 Paul D. Smith <psmith@gnu.org>
2186 Fix Savannah bug # 1328.
2188 * configure.in: Check for atexit().
2189 * misc.c (close_stdout): Test stdout to see if writes to it have
2190 failed. If so, be sure to exit with a non-0 error code. Based on
2191 code found in gnulib.
2192 * make.h: Prototype.
2193 * main.c (main): Install close_stdout() with atexit().
2195 2005-06-10 Paul D. Smith <psmith@gnu.org>
2197 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2199 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2200 headers; make vmsWaitForChildren() static; extern vmsify().
2201 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2202 Don't create child_execute_job() here (it's in vmsjobs.c).
2203 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2205 2005-06-09 Paul D. Smith <psmith@gnu.org>
2207 * variable.c (push_new_variable_scope): File variables point
2208 directly to the global_setlist variable. So, inserting a new
2209 scope in front of that has no effect on those variables: they
2210 don't go through current_variable_set_list. If we're pushing a
2211 scope and the current scope is global, push it "the other way" so
2212 that the new setlist is in the global_setlist variable, and
2213 next points to a new setlist with the global variable set.
2214 (pop_variable_scope): Properly undo a push with the new
2215 semantics.
2216 Fixes Savannah bug #11913.
2218 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2220 * job.c (reap_children): Don't die of the command failed but
2221 the dontcare flag is set. Fixes Savannah bug #13216.
2223 * implicit.c (pattern_search): When creating a target from
2224 an implicit rule match, lookup pattern target and set precious
2225 flag in a newly created target. Fixes Savannah bug #13218.
2227 2005-05-13 Paul D. Smith <psmith@gnu.org>
2229 Implement "if... else if... endif" syntax.
2231 * read.c (eval): Push all checks for conditional words ("ifeq",
2232 "else", etc.) down into the conditional_line() function.
2233 (conditional_line): Rework to allow "else if..." clause. New
2234 return value -2 for lines which are not conditionals. The
2235 ignoring flag can now also be 2, which means "already parsed a
2236 true branch". If that value is seen no other branch of this
2237 conditional can be considered true. In the else parsing if there
2238 is extra text after the else, invoke conditional_line()
2239 recursively to see if it's another conditional. If not, it's an
2240 error. If so, raise the conditional value to this level instead
2241 of creating a new conditional nesting level. Special check for
2242 "else" and "endif", which aren't allowed on the "else" line.
2243 * doc/make.texi (Conditional Syntax): Document the new syntax.
2245 2005-05-09 Paul D. Smith <psmith@gnu.org>
2247 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2248 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2249 recurses to the w32 directory, even on non-Windows systems. Use
2250 the method suggested in the automake manual.
2251 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2252 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2254 2005-05-07 Paul D. Smith <psmith@gnu.org>
2256 * main.c (die): If we're dying with a fatal error (not that a
2257 command has failed), write back any leftover tokens before we go.
2259 * job.c (set_child_handler_action_flags): If there are jobs
2260 waiting for the load to go down, set an alarm to go off in 1
2261 second. This allows us to wake up from a potentially long-lasting
2262 read() and start a new job if the load has gone down. Turn it off
2263 after the read.
2264 (job_noop): Dummy signal handler function.
2265 (new_job): Invoke it with the new semantics.
2267 * docs/make.texi: Document secondary expansion. Various cleanups
2268 and random work.
2270 2005-05-03 Paul D. Smith <psmith@gnu.org>
2272 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2273 the targets which are to ultimately be made are called "goals";
2274 see the GNU make manual. Also, MAKECMDGOALS, etc.
2276 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2277 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2278 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2280 2005-05-02 Paul D. Smith <psmith@gnu.org>
2282 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2283 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2284 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2285 functions to vmsjobs.c. #include it into jobs.c.
2287 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2288 jobserver tokens. I found that this happens when an exported
2289 recursive variable contains a $(shell ...) function reference: in
2290 this situation we could "forget" to write back a token.
2292 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2293 we have. It's not reliable to depend on the number of children in
2294 our linked list so keep a separate count.
2295 (new_job): Check jobserver_tokens rather than children &&
2296 waiting_jobs. Increment jobserver_tokens when we get one.
2297 (free_child): If jobserver_tokens is 0, internal error. If it's
2298 >1, write a token back to the jobserver pipe (we don't write a
2299 token for the "free" job). Decrement jobserver_tokens.
2301 * main.c: Add variable master_job_slots.
2302 (main): Set it to hold the number of jobs requested if we're the
2303 master process, when using the jobserver.
2304 (die): Sanity checks: first test jobserver_tokens to make sure
2305 this process isn't holding any tokens we didn't write back.
2306 Second, if master_job_slots is set count the tokens left in the
2307 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2309 2005-04-24 Paul D. Smith <psmith@gnu.org>
2311 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2312 with -l# can lose jobserver tokens, because waiting jobs are not
2313 consulted properly when checking for the "free" token.
2315 * job.c (free_child): Count waiting_jobs as having tokens.
2316 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2317 handle jobs waiting for the load to drop.
2319 2005-04-23 Paul D. Smith <psmith@gnu.org>
2321 * main.c (main): Be careful to not core if a variable setting in
2322 the environment doesn't contain an '='. This is illegal but can
2323 happen in broken setups.
2324 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2326 2005-04-12 Paul D. Smith <psmith@gnu.org>
2328 The second expansion feature causes significant slowdown. Timing
2329 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2330 read the makefile before the feature, to 11+s to do the same
2331 operations after the feature. Additionally, memory usage
2332 increased drastically. To fix this I added some intelligence that
2333 avoids the overhead of the second expansion unless it's required.
2335 * dep.h: Add a new boolean field, need_2nd_expansion.
2337 * read.c (eval): When creating the struct dep for the target,
2338 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2339 (record_files): If there's a "%" in a static pattern rule, it gets
2340 converted to "$*" so set need_2nd_expansion to 1.
2342 * file.c (expand_deps): Rework to be more efficient. Only perform
2343 initialize_file_variables(), set_file_variables(), and
2344 variable_expand_for_file() if the need_2nd_expansion is set.
2346 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2347 (pattern_search): Ditto.
2348 * main.c (handle_non_switch_argument): Ditto.
2349 (main): Ditto.
2350 * read.c (read_all_makefiles): Ditto.
2351 (eval_makefile): Ditto.
2353 2005-04-07 Paul D. Smith <psmith@gnu.org>
2355 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2356 * variable.c (sync_Path_environment): Ditto.
2357 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2359 * main.c (main): Define the .FEATURES variable.
2360 * NEWS: Announce .FEATURES.
2361 * doc/make.texi (Special Variables): Document .FEATURES.
2363 * remake.c (check_dep): If a file is .PHONY, update it even if
2364 it's marked intermediate. Fixes Savannah bug #12331.
2366 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2368 * file.c (expand_deps): Factor out the second expansion and
2369 prerequisite line parsing logic from snap_deps().
2371 * file.c (snap_deps): Use expand_deps(). Expand and parse
2372 prerequisites of the .SUFFIXES special target first. Fixes
2373 Savannah bug #12320.
2375 2005-03-13 Paul D. Smith <psmith@gnu.org>
2377 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2378 Zaretskii.
2380 2005-03-11 Paul D. Smith <psmith@gnu.org>
2382 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2383 available, not undefined (from Earnie Boyd).
2385 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2387 * implicit.c (pattern_search): Mark an intermediate target as
2388 precious if it happened to be a prerequisite of some (other)
2389 target. Fixes Savannah bug #12267.
2391 2005-03-09 Paul D. Smith <psmith@gnu.org>
2393 * read.c (eval_makefile): Add alloca(0).
2394 (eval_buffer): Ditto.
2396 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2398 * main.c (main): Use o_file instead of o_default when defining
2399 the .DEFAULT_TARGET special variable.
2400 * read.c (eval): Use define_variable_global() instead of
2401 define_variable() when setting new value for the .DEFAULT_TARGET
2402 special variable. Fixes Savannah bug #12266.
2404 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2406 * imlicit.c (pattern_search): Mark files for which an implicit
2407 rule has been found as targets. Fixes Savannah bug #12202.
2409 2005-03-04 Paul D. Smith <psmith@gnu.org>
2411 * AUTHORS: Update.
2412 * doc/make.texi (Automatic Variables): Document $|.
2414 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2416 * read.c (record_files): Instead of substituting % with
2417 actual stem value in dependency list replace it with $*.
2418 This fixes stem triple expansion bug.
2420 * implicit.c (pattern_search): Copy stem to a separate
2421 buffer and make it a properly terminated string. Assign
2422 this buffer instead of STEM (which is not terminated) to
2423 f->stem. Instead of substituting % with actual stem value
2424 in dependency list replace it with $*. This fixes stem
2425 triple expansion bug.
2427 2005-03-01 Paul D. Smith <psmith@gnu.org>
2429 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2430 on Windows, as it takes a handle not a pid. Just exit.
2431 Fix from patch #3679, provided by Alessandro Vesely.
2433 * configure.in: Update check for sys_siglist[] from autoconf manual.
2434 * signame.c (strsignal): Update to use the new autoconf macro.
2436 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2438 * read.c (record_files): Add a check for the list of prerequisites
2439 of a static pattern rule being empty. Fixes Savannah bug #12180.
2441 2005-02-28 Paul D. Smith <psmith@gnu.org>
2443 * doc/make.texi (Text Functions): Update docs to allow the end
2444 ordinal for $(wordlist ...) to be 0.
2445 * function.c (func_wordlist): Fail if the start ordinal for
2446 $(wordlist ...) is <1. Matches documentation.
2447 Resolves Savannah support request #103195.
2449 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2450 previously we were stopping when !-q, exactly the opposite. This
2451 has been wrong since version 1.34, in 1994!
2452 (update_file): If we got an error don't break out to run more
2453 double-colon rules: just return immediately.
2454 Fixes Savannah bug #7144.
2456 2005-02-27 Paul D. Smith <psmith@gnu.org>
2458 * misc.c (end_of_token): Make argument const.
2459 * make.h: Update prototype.
2461 * function.c (abspath, func_realpath, func_abspath): Use
2462 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2463 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2464 * read.c (record_files): Ditto.
2465 * variable.c (do_variable_definition): Ditto.
2467 * function.c (func_error): Create a new function $(info ...) that
2468 simply prints the message to stdout with no extras.
2469 (function_table_init): Add new function to the table.
2470 * NEWS: Add $(info ...) reference.
2471 * doc/make.texi (Make Control Functions): Document it.
2473 New feature: if the system supports symbolic links, and the user
2474 provides the -L/--check-symlink-time flag, then use the latest
2475 mtime between the symlink(s) and the target file.
2477 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2478 readlink(). If both are available, define MAKE_SYMLINKS.
2479 * main.c: New variable: check_symlink_flag.
2480 (usage): Add a line for -L/--check-symlink-times to the help string.
2481 (switches): Add -L/--check-symlink-times command line argument.
2482 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2483 print a warning and disable it again.
2484 * make.h: Declare check_symlink_flag.
2485 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2486 if the file is a symlink then check each link in the chain and
2487 choose the NEWEST mtime we find as the mtime for the file. The
2488 newest mtime might be the file itself!
2489 * NEWS: Add information about this new feature.
2490 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2492 Avoid core dumps described in Savannah bug # 12124:
2494 * file.c: New variable snapped_deps remember whether we've run
2495 snap_deps().
2496 (snap_deps): Set it.
2497 * filedef.h: Extern it.
2498 * read.c (record_files): Check snapped_deps; if it's set then
2499 we're trying to eval a new target/prerequisite relationship from
2500 within a command script, which we don't support. Fatal.
2502 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2504 Implementation of the .DEFAULT_TARGET special variable.
2506 * read.c (eval): If necessary, update default_target_name when
2507 reading rules.
2508 * read.c (record_files): Update default_target_file if
2509 default_target_name has changed.
2510 * main.c (default_target_name): Define.
2511 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2512 default_target_name is set use default_target_file as a root
2513 target to make.
2514 * filedef.h (default_target_name): Declare.
2515 * dep.h (free_dep_chain):
2516 * misc.c (free_dep_chain): Change to operate on struct nameseq
2517 and change name to free_ns_chain.
2518 * file.c (snap_deps): Update to use free_ns_chain.
2520 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2522 Implementation of the second expansion in explicit rules,
2523 static pattern rules and implicit rules.
2525 * read.c (eval): Refrain from chopping up rule's dependencies.
2526 Store them in a struct dep as a single dependency line. Remove
2527 the code that implements SySV-style automatic variables.
2529 * read.c (record_files): Adjust the code that handles static
2530 pattern rules to expand all percents instead of only the first
2531 one. Reverse the order in which dependencies are stored so that
2532 when the second expansion reverses them again they appear in
2533 the makefile order (with some exceptions, see comments in
2534 the code). Remove the code that implements SySV-style automatic
2535 variables.
2537 * file.c (snap_deps): Implement the second expansion and chopping
2538 of dependency lines for explicit rules.
2540 * implicit.c (struct idep): Define an auxiliary data type to hold
2541 implicit rule's dependencies after stem substitution and
2542 expansion.
2544 * implicit.c (free_idep_chain): Implement.
2546 * implicit.c (get_next_word): Implement helper function for
2547 parsing implicit rule's dependency lines into words taking
2548 into account variable expansion requests. Used in the stem
2549 splitting code.
2551 * implicit.c (pattern_search): Implement the second expansion
2552 for implicit rules. Also fixes bug #12091.
2554 * commands.h (set_file_variables): Declare.
2555 * commands.c (set_file_variables): Remove static specifier.
2557 * dep.h (free_dep_chain): Declare.
2558 * misc.c (free_dep_chain): Implement.
2560 * variable.h (variable_expand_for_file): Declare.
2561 * expand.c (variable_expand_for_file): Remove static specifier.
2563 * make.h (strip_whitespace): Declare.
2564 * function.c (strip_whitespace): Remove static specifier.
2566 2005-02-26 Paul D. Smith <psmith@gnu.org>
2568 * main.c (main): Check for ferror() when reading makefiles from stdin.
2569 Apparently some shells in Windows don't close pipes properly and
2570 require this check.
2572 2005-02-24 Jonathan Grant <jg@jguk.org>
2574 * configure.in: Add MinGW configuration options, and extra w32 code
2575 directory.
2576 * Makefile.am: Add MinGW configuration options, and extra w32 code
2577 directory.
2578 * main.c: Determine correct program string (after last \ without .exe).
2579 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2580 type fix x2
2581 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2582 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2583 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2584 environment support.
2586 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2588 * function.c (func_shell): When initializing error_prefix, check
2589 that reading file name is not null. This fixes long-standing
2590 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2592 2005-02-09 Paul D. Smith <psmith@gnu.org>
2594 * maintMakefile: Update the CVS download URL to simplify them.
2595 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2596 downloading the .texi files from Savannah now.
2598 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2600 * main.c (handle_non_switch_argument): Only add variables to
2601 command_variables if they're not already there: duplicate settings
2602 waste space and can be confusing to read.
2604 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2605 this header is never included by non-WINDOWS32 code, and it
2606 requires <config.h> to define which isn't always included first.
2608 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2609 testing MINGW32 versions.
2611 * main.c (log_working_directory): flush stdout to be sure the WD
2612 change is printed before any stderr messages show up.
2614 2005-02-01 Paul D. Smith <psmith@gnu.org>
2616 * maintMakefile (po_repo): Update the GNU translation site URL.
2618 2004-12-01 Paul D. Smith <psmith@gnu.org>
2620 * main.c (main): Change char* env_shell to struct variable shell_var.
2621 * variable.c (target_environment): Use new shell_var.
2623 2004-11-30 Paul D. Smith <psmith@gnu.org>
2625 * configure.in: The old way we avoided creating build.sh from
2626 build.sh.in before build.sh.in exists doesn't work anymore; we
2627 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2628 the help!). This also keeps automake from complaining.
2629 * Makefile.am (README): Add a dummy target so automake won't
2630 complain that this file doesn't exist when we checkout from CVS.
2631 * maintMakefile (.dep_segment): Rewrite this rule since newer
2632 versions of automake don't provide DEP_FILES.
2634 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2636 Implementation of `realpath' and `abspath' built-in functions.
2638 * configure.in: Check for realpath.
2639 * function.c (abspath): Return an absolute file name that does
2640 not contain any `.' or `..' components, nor repeated `/'.
2641 * function.c (func_abspath): For each name call abspath.
2642 * function.c (func_realpath): For each name call realpath
2643 from libc or delegate to abspath if realpath is not available.
2644 * doc/make.texi (Functions for File Names): Document new functions.
2645 * doc/make.texi (Quick Reference): Ditto.
2647 2004-11-28 Paul D. Smith <psmith@gnu.org>
2649 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2650 arguments. Fixes bug #10252.
2652 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2654 * main.c (main): Set SHELL to v_noexport by default. Remember the
2655 original environment setting of SHELL in the env_shell variable.
2656 * main.h: Export new env_shell variable.
2657 * variable.c (target_environment): If we find a v_noexport
2658 variable for SHELL, add a SHELL variable with the env_shell value.
2659 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2660 * doc/make.texi (Variables/Recursion): Ditto.
2662 2004-11-28 Paul D. Smith <psmith@gnu.org>
2664 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2665 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2666 Patch by Alessandro Vesely.
2668 2004-11-12 Paul D. Smith <psmith@gnu.org>
2670 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2671 the command line if it's inside a string.
2672 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2674 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2676 * function.c (func_lastword): New function: return last word
2677 from the list of words.
2678 * doc/make.texi: Document $(lastword ). Fix broken links in
2679 Quick Reference section.
2681 2004-10-06 Paul D. Smith <psmith@gnu.org>
2683 Apply patch from Alessandro Vesely, provided with bug # 9748.
2684 Fix use of tmpnam() to work with Borland C.
2686 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2687 construction of a temporary filename, and call new function
2688 create_batch_filename().
2689 (create_batch_filename) [WINDOWS32]: New function to create a
2690 temporary filename.
2692 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2694 * read.c (record_target_var): Expand simple pattern-specific
2695 variable.
2696 * variable.c (initialize_file_variables): Do not expand simple
2697 pattern-specific variable.
2699 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2701 * remake.c (update_file_1): When rebuilding makefiles inherit
2702 dontcare flag from a target that triggered update.
2704 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2706 * variable.c (initialize_file_variables): Mark pattern-specific
2707 variable as a per-target and copy export status.
2709 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2711 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2713 * implicit.c (pattern_search): When considering an implicit rule's
2714 prerequisite check that it is actually a target rather then
2715 just an entry in the file hashtable.
2717 2004-09-21 Paul D. Smith <psmith@gnu.org>
2719 * read.c (readstring): Fix some logic errors in backslash handling.
2720 (eval): Remove some unnecessary processing in buffer handling.
2721 (record_target_var): Assert that parse_variable_definition() succeeded.
2722 Reported by: Markus Mauhart <qwe123@chello.at>.
2724 * misc.c: Removed the sindex() function. All instances of this
2725 function were trivially replaceable by the standard strstr()
2726 function, and that function will always have better (or certainly
2727 no worse) performance than the very simple-minded algorithm
2728 sindex() used. This can matter with complex makefiles.
2729 * make.h: Remove the prototype for sindex().
2730 * function.c (subst_expand): Convert sindex() call to strstr().
2731 This means we no longer need to track the TLEN value so remove that.
2732 (func_findstring): Convert sindex() to strstr().
2733 * commands.c (chop_commands): Convert sindex() calls to strstr().
2734 Suggested by: Markus Mauhart <qwe123@chello.at>.
2736 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2737 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2738 If SHELL is set to CMD.EXE then assume it's batch-mode and
2739 non-unixy. I wrote the code differently from the patch, though,
2740 to make it safer. This also resolves bug #9174.
2742 2004-09-20 Paul D. Smith <psmith@gnu.org>
2744 * expand.c (variable_expand_string): Modify to invoke
2745 patsubst_expand() instead of subst_expand(); the latter didn't
2746 handle suffix patterns correctly.
2747 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2748 was used only from variable_expand_string() and is no longer used
2749 there.
2750 (func_subst): Ditto, on call to subst_expand().
2751 (patsubst_expand): Require the percent pointers to point to the
2752 character after the %, not to the % itself.
2753 * read.c (record_files): New call criteria for patsubst_expand().
2754 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2755 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2757 2004-09-19 Paul D. Smith <psmith@gnu.org>
2759 * function.c (subst_expand): Fix a check in by_word: look for a
2760 previous blank if we're beyond the beginning of the string, not
2761 the beginning of the word.
2762 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2764 2004-05-16 Paul D. Smith <psmith@gnu.org>
2766 * remake.c (update_goal_chain): Change the argument specifying
2767 whether we're rebuilding makefiles to be a global variable,
2768 REBUILDING_MAKEFILES.
2769 (complain): Extract the code that complains about no rules to make
2770 a target into a separate function.
2771 (update_file_1): If we tried to rebuild a file during the makefile
2772 rebuild phase and it was dontcare, then no message was printed.
2773 If we then try to build the same file during the normal build,
2774 print a message this time.
2775 (remake_file): Don't complain about un-remake-able files when
2776 we're rebuilding makefiles.
2778 2004-05-11 Paul D. Smith <psmith@gnu.org>
2780 * job.c (construct_command_argv_internal): OS/2 patches from
2781 Andreas Buening <andreas.buening@nexgo.de>.
2783 2004-05-10 Paul D. Smith <psmith@gnu.org>
2785 * remake.c (update_file): Don't walk the double-colon chain unless
2786 this is a double-colon rule. Fix suggested by Boris Kolpackov
2787 <boris@kolpackov.net>.
2789 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2790 * readme.vms: New section describing OpenVMS support and issues.
2791 * default.c (default_variables): Add support for IA64.
2792 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2793 without some privilege aborts make with the error
2794 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2795 pressing Ctrl+Y and the input device is no terminal. The change
2796 catches this error and just continues.
2798 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2800 2004-04-25 Paul D. Smith <psmith@gnu.org>
2802 * commands.c (set_file_variables): Set $< properly in the face of
2803 order-only prerequisites.
2804 Patch from Boris Kolpackov <boris@kolpackov.net>
2806 2004-04-21 Bob Byrnes <byrnes@curl.com>
2808 * main.c (main): Notice failures to remake makefiles.
2810 2004-03-28 Paul D. Smith <psmith@gnu.org>
2812 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2814 * job.c: No default shell for RISC OS.
2815 (load_too_high): Hard-code the return to 1.
2816 (construct_command_argv_internal): No sh_chars or sh_cmds.
2817 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2819 2004-03-20 Paul D. Smith <psmith@gnu.org>
2821 * variable.c (do_variable_definition): Don't append from the
2822 global set if a previous non-appending target-specific variable
2823 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2824 (with fix).
2826 * expand.c (reference_variable): Don't give up on variables with
2827 no value that have the target-specific append flag set: they might
2828 have a value after all. Reported by Oliver Schmidt
2829 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2830 <nikulin@dx1cmd.inp.nsk.su>.
2832 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2833 refer to absolute pathnames in directories that don't exist: some
2834 portion of the makefile could create those directories before we
2835 match the pattern. Fixes bugs #775 and #108.
2837 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2839 * main.c (main): Free makefile_mtimes if we have any.
2840 * README.W32.template: Update documentation for the current status
2841 of the MS-Windows port.
2842 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2843 environment variable is sometimes already defined which causes the
2844 build to fail.
2845 * main.c (debug_signal_handler): Only define this function if
2846 SIGUSR1 is available.
2848 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2850 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2851 * README.OS2.template: Documentation updates.
2852 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2853 link line for safety.
2854 * maintMakefile (build.sh.in): Remove an extraneous ")".
2855 * job.c (child_execute_job): Close saved FDs.
2856 * job.c (exec_command) [OS/2]: exec_command(): If the command
2857 can't be exec'ed and if the shell is not Unix-sh, then try again
2858 with argv = { "cmd", "/c", ... }. Normally, this code is never
2859 reached for the cmd shell unless the command really doesn't exist.
2860 (construct_command_argv_internal) [OS/2]: The code for cmd
2861 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2862 The CMD builtin commands are case insensitive so use strcasecmp().
2864 2004-03-19 Paul D. Smith <psmith@gnu.org>
2866 * read.c (do_define): Re-order line counter increment so the count
2867 is accurate (we were losing one line per define). Reported by
2868 Dave Yost <Dave@Yost.com>.
2870 2004-03-06 Paul D. Smith <psmith@gnu.org>
2872 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2873 compiler.
2874 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2875 * misc.c (message,error,fatal): Ditto.
2876 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2877 * config.h.W32.template: Ditto.
2878 * config.h-vms.template: Ditto.
2879 * config.ami.template: Ditto.
2881 2004-03-04 Paul D. Smith <psmith@gnu.org>
2883 * README.template: Add a note about broken /bin/sh on SunOS
2884 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2886 * misc.c (message, error, fatal): Don't use "..." if we're using
2887 varargs. ansi2knr should handle this but it doesn't work: it
2888 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2889 done. On many systems (SunOS for example) va_dcl is a #define.
2890 So, force the use of the non-"..." version on pre-ANSI compilers.
2892 * maintMakefile (sign-dist): Create some rules to help automate
2893 the new GNU ftp upload method.
2895 2004-02-24 Paul D. Smith <psmith@gnu.org>
2897 * config.h.W32.template: Add HAVE_STDARG_H
2898 * config.h-vms.template: Ditto.
2899 * config.ami.template: Ditto.
2901 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2903 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2904 * build_w32.bat: Remove extra "+".
2906 2004-02-23 Paul D. Smith <psmith@gnu.org>
2908 * make.h: Create an UNUSED macro to mark unused parameters.
2909 * (many): Clean up warnings by applying UNUSED, fixing
2910 signed/unsigned incompatibilities, etc.
2912 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2913 autoconf warnings.
2914 * filedef.h: Name the command_state enumeration.
2915 * file.c (set_command_state): Use the enumeration in the function
2916 argument.
2918 * configure.in: Explicitly set SET_MAKE to empty, to disable
2919 MAKE=make even when no make already exists. Fix bug #3823.
2921 2004-02-22 Paul D. Smith <psmith@gnu.org>
2923 * maintMakefile: Perl script to clean up all non-CVS files. Use
2924 it on all the subdirectories for the cvs-clean target.
2926 * main.c (decode_switches): Require non-empty strings for all our
2927 string command-line options. Fixes Debian bug # 164165.
2929 * configure.in: Check for stdarg.h and varargs.h.
2930 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2931 for printing messages.
2932 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2933 (message): Ditto.
2934 (error): Ditto.
2935 (fatal): Ditto.
2937 A number of patches for OS/2 support from Andreas Buening
2938 <andreas.buening@nexgo.de>:
2940 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2941 disable the SIGCHLD handler.
2942 (reap_children) [OS/2]: Remove special handling of job_rfd.
2943 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2944 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2945 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2946 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2947 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2948 systems.
2950 2004-02-21 Paul D. Smith <psmith@gnu.org>
2952 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2953 <mail@kristov.de> reports that if process_begin() fails we don't
2954 handle the error condition correctly in all cases.
2955 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2956 to have a newline on the message.
2958 * job.c (construct_command_argv_internal): Add "test" to UNIX
2959 sh_cmds[]. Fixes Savannah bug # 7606.
2961 2004-02-04 Paul D. Smith <psmith@gnu.org>
2963 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2964 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2965 Hartmut Becker <Hartmut.Becker@hp.com>.
2967 2004-01-21 Paul D. Smith <psmith@gnu.org>
2969 * job.c (load_too_high): Implement an algorithm to control the
2970 "thundering herd" problem when using -l to control job creation
2971 via the load average. The system only recomputes the load once a
2972 second but we can start many jobs in a second. To solve this we
2973 keep track of the number of jobs started in the last second and
2974 apply a weight to try to guess what a correct load would be.
2975 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2976 Also fixes bug #4693.
2977 (reap_children): Decrease the job count for this second.
2978 (start_job_command): Increase the job count for this second.
2980 * read.c (conditional_line): Expand the text after ifn?def before
2981 checking to see if it's a single word. Fixes bug #7257.
2983 2004-01-09 Paul D. Smith <psmith@gnu.org>
2985 * file.c (print_file): Recurse to print all targets in
2986 double-colon rules. Fixes bug #4518, reported (with patch) by
2987 Andrew Chatham <chatham@google.com>.
2989 2004-01-07 Paul D. Smith <psmith@gnu.org>
2991 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2992 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2993 AC_FUNC_SETVBUF_REVERSED.
2995 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2996 (MAKE Variable): Fix Savannah bug #4898.
2998 * job.c (construct_command_argv_internal): Add "!" to the list of
2999 shell escape chars. POSIX sh allows it to appear before a
3000 command, to negate the exit code. Fixes bug #6404.
3002 * implicit.c (pattern_search): When matching an implicit rule,
3003 remember which dependencies have the ignore_mtime flag set.
3004 Original fix provided in Savannah patch #2349, by Benoit
3005 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3007 2003-11-22 Paul D. Smith <psmith@gnu.org>
3009 * README.W32.template (Outputs): Clarification on -j with
3010 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3011 <jg-make@jguk.org>.
3013 2003-11-02 Paul D. Smith <psmith@gnu.org>
3015 * function.c (func_if): Strip all the trailing whitespace from the
3016 condition, then don't expand it. Fixed bug # 5798.
3018 * expand.c (recursively_expand_for_file): If we're expanding a
3019 variable with no file context, then use the variable's context.
3020 Fixes bug # 6195.
3022 2003-10-21 Paul D. Smith <psmith@gnu.org>
3024 * main.c (log_working_directory): Add newlines to printf()s.
3026 * README.cvs: Add a note to ignore warnings during autoreconf.
3028 * maintMakefile (po_repo): Set a new URL for PO file updates.
3029 (get-config/config.guess get-config/config.sub): Get these files
3030 from the Savannah config project instead of ftp.gnu.org.
3032 2003-10-05 Paul Eggert <eggert@twinsun.com>
3034 * main.c (main): Avoid potential subscript error if environ has
3035 short strings.
3037 2003-08-22 Paul D. Smith <psmith@gnu.org>
3039 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3040 systems which don't yet implement the C89 standard :-/.
3042 2003-07-18 Paul D. Smith <psmith@gnu.org>
3044 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3045 [WINDOWS32]: Initialize hash.
3047 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3049 * dir.c (read_dirstream): Provide a workaround for broken versions of
3050 the MinGW dirent structure.
3052 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3054 * w32/include/dirent.h: Add __MINGW32__ filter.
3056 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3058 * make.h: Add global declaration of *make_host.
3059 * main.c (print_usage): Remove local declaration of *make_host.
3060 (print_version): Display "This program built for ..." after Copyright
3061 notice.
3063 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3065 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3066 execution of "makeinfo --html make.texi".
3068 2003-04-30 Paul D. Smith <psmith@gnu.org>
3070 * build.template: Make some changes to maybe allow this script to
3071 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3073 * README.OS2.template: New file for OS/2 support. Original
3074 contributed by Andreas Buening.
3075 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3076 DOS-style paths.
3078 2003-04-19 Paul D. Smith <psmith@gnu.org>
3080 Fix bug #1405: allow a target to match multiple pattern-specific
3081 variables.
3083 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3084 variable.c, where they've always belonged.
3085 * rule.h: Move the prototypes and struct pattern_var as well.
3086 * variable.c (initialize_file_variables): Invoke
3087 lookup_pattern_var() in a loop, until no more matches are found.
3088 If a match is found, create a new variable set for the target's
3089 pattern variables. Then merge the contents of each matching
3090 pattern variable set into the target's pattern variable set.
3091 (lookup_pattern_var): Change this function to be usable
3092 in a loop. It takes a starting position: if NULL, start at the
3093 beginning; if non-NULL, start with the pattern variable after that
3094 position, and return the next matching pattern.
3095 (create_pattern_var): Create a unique instance of
3096 pattern-specific variables for every definition in the makefile.
3097 Don't combine the same pattern together. This allows us to
3098 process the variable handling properly even when the same pattern
3099 is used multiple times.
3100 (parse_variable_definition): New function: break out the parsing
3101 of a variable definition line from try_variable_definition.
3102 (try_variable_definition): Call parse_variable_definition to
3103 parse.
3104 (print_variable_data_base): Print out pattern-specific variables.
3105 * variable.h (struct variable): Remember when a variable is
3106 conditional. Also remember its flavor.
3107 (struct pattern_var): Instead of keeping a variable set, we just
3108 keep a single variable for each pattern.
3109 * read.c (record_target_var): Each pattern variable contains only a
3110 single variable, not a set, so create it properly.
3111 * doc/make.texi (Pattern-specific): Document the new behavior.
3113 2003-04-17 Paul D. Smith <psmith@gnu.org>
3115 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3116 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3117 file/directory naming rules for VMS so I can't tell whether this
3118 is correct or not.
3120 2003-04-09 Paul D. Smith <psmith@gnu.org>
3122 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3123 DOS-style pathnames: backslash separators and drive specifiers.
3125 2003-03-28 Paul D. Smith <psmith@gnu.org>
3127 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3128 the intermediate flag on all targets. Fixes bug #2515.
3130 2003-03-24 Paul D. Smith <psmith@gnu.org>
3132 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3133 Upgrade to autoconf 2.57 and automake 1.7.3.
3135 * job.c: More OS/2 changes from Andreas Buening.
3137 * file.c (print_file): Fix variable initialization.
3138 Fixes bug #2892.
3140 * remake.c (notice_finished_file):
3142 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3143 some calls (like readdir()) return NULL in valid situations
3144 without resetting errno. Fixes bug #2846.
3146 2003-02-25 Paul D. Smith <psmith@gnu.org>
3148 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3150 * job.c (_is_unixy_shell) [OS/2]: New function.
3151 Set default shell to /bin/sh.
3152 (reap_children): Close the job_rfd pipe here since we don't use a
3153 SIGCHLD handler.
3154 (set_child_handler_action_flags): define this to empty on OS/2.
3155 (start_job_command): Close the jobserver pipe and use
3156 child_execute_job() instead of fork/exec.
3157 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3158 rather than exec'ing, then reconfigure stdin/stdout.
3159 (exec_command): Rewrite to use spawn instead of exec. Return the
3160 PID of the child.
3162 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3163 in DOS. Handle the TEMP environment variable as in DOS. Don't
3164 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3165 use -j in DOS mode. Use child_execute_job() instead of
3166 exec_command().
3168 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3169 spawn() instead.
3171 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3172 prototypes that return values.
3174 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3176 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3177 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3178 for OS/2.
3179 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3180 DOS paths.
3182 2003-02-24 Paul D. Smith <psmith@gnu.org>
3184 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3185 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3186 (child_execute_job) [VMS]: Handle error status properly.
3187 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3189 * function.c (func_shell): Use EINTRLOOP() while reading from the
3190 subshell pipe (Fixes bug #2502).
3191 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3192 jobserver pipe.
3193 * main.c (main): Ditto.
3195 2003-01-30 Paul D. Smith <psmith@gnu.org>
3197 * read.c (eval): eval() was not fully reentrant, because the
3198 collapsed buffer was static. Change it to be an automatic
3199 variable so that eval() can be invoked recursively.
3200 Fixes bug # 2238.
3201 (eval): Apply patch # 1022: fix memory reference error on long
3202 target-specific variable lines.
3203 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3205 * function.c (check_numeric): Combine the is_numeric() function
3206 into this function, since it's only called from one place.
3207 Constify this function. Have it print the incorrect string in the
3208 error message. Fixes bug #2407.
3209 (strip_whitespace): Constify.
3210 (func_if): Constify.
3211 * expand.c (expand_argument): Constify.
3213 2003-01-29 Paul D. Smith <psmith@gnu.org>
3215 Fix bug # 2169, also reported by other people on various systems.
3217 * make.h: Some systems, such as Solaris and PTX, do not fully
3218 implement POSIX-compliant SA_RESTART functionality; important
3219 system calls like stat() and readdir() can still fail with EINTR
3220 even if SA_RESTART has been set on the signal handler. So,
3221 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3222 EINTR for system calls which return -1 or 0 (NULL), respectively,
3223 on error.
3224 Also, remove the old atomic_stat()/atomic_readdir() and
3225 HAVE_BROKEN_RESTART handling.
3227 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3229 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3230 * remake.c (touch_file): Ditto.
3232 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3233 * read.c (construct_include_path): Ditto.
3234 * remake.c (name_mtime): Ditto.
3235 * vpath.c (selective_vpath_search): Ditto.
3236 * dir.c (find_directory): Ditto.
3237 (local_stat): Ditto.
3238 (find_directory): Use ENULLLOOP() to wrap opendir().
3239 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3241 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3242 atomic_readdir() handling.
3244 2003-01-22 Paul D. Smith <psmith@gnu.org>
3246 * function.c (func_call): Fix Bug #1744. If we're inside a
3247 recursive invocation of $(call ...), mask any of the outer
3248 invocation's arguments that aren't used by this one, so that this
3249 invocation doesn't "inherit" them accidentally.
3251 2002-12-05 Paul D. Smith <psmith@gnu.org>
3253 * function.c (subst_expand): Valery Khamenia reported a
3254 pathological performance hit when doing substitutions on very
3255 large values with lots of words: turns out we were invoking
3256 strlen() a ridiculous number of times. Instead of having each
3257 call to sindex() call strlen() again, keep track of how much of
3258 the text we've seen and pass the length to sindex().
3260 2002-11-19 Paul D. Smith <psmith@gnu.org>
3262 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3265 2002-11-16 Paul D. Smith <psmith@gnu.org>
3267 * NMakefile.template (OBJS): Add hash.c object file.
3268 * SMakefile.template (srcs): Ditto.
3269 * Makefile.ami (objs): Ditto.
3270 * build_w32.bat: Ditto.
3272 * Makefile.DOS.template: Remove extra dependencies.
3274 2002-10-25 Paul D. Smith <psmith@gnu.org>
3276 * expand.c (install_variable_buffer): New function. Install a new
3277 variable_buffer context and return the previous one.
3278 (restore_variable_buffer): New function. Free the current
3279 variable_buffer context and put a previously saved one back.
3280 * variable.h: Prototypes for {install,restore}_variable_buffer.
3281 * function.c (func_eval): Push a new variable_buffer context
3282 before we eval, then restore the old one when we're done.
3283 Fixes Bug #1517.
3285 * read.c (install_conditionals): New function. Install a new
3286 conditional context and return the previous one.
3287 (restore_conditionals): New function. Free the current
3288 conditional context and put a previously saved one back.
3289 (eval): Use the {install,restore}_conditionals for "include"
3290 handling.
3291 (eval_buffer): Use {install,restore}_conditionals to preserve the
3292 present conditional state before we evaluate the buffer.
3293 Fixes Bug #1516.
3295 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3296 and $(value ...).
3297 (Recursion): Add a variable index entry for CURDIR.
3299 * README.cvs: Update to appropriate versions.
3300 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3301 don't need to copy loadavg.c: automake is smart enough to create
3302 it for me. Still have a bug in automake related to ansi2knr tho.
3304 2002-10-14 Paul D. Smith <psmith@gnu.org>
3306 * remake.c (notice_finished_file): Only touch targets if they have
3307 at least one command (as per POSIX). Resolve Bug #1418.
3309 * *.c: Convert to using ANSI C-style function definitions.
3310 * Makefile.am: Enable the ansi2knr feature of automake.
3311 * configure.in: ditto.
3313 2002-10-13 Paul D. Smith <psmith@gnu.org>
3315 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3316 for automatic variable values like $^, etc. In the case of very
3317 large lists of prerequisites this causes problems. Instead reuse
3318 a static buffer (resizeable) for each variable.
3320 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3321 target-specific variable definitions. Check for it and set an
3322 "exported" flag.
3323 (record_target_var): Set the export field to v_export if the
3324 "exported" flag is set.
3325 * doc/make.texi (Target-specific): Document the ability to use
3326 "export".
3328 * doc/make.texi: Change the name of the section on automatic
3329 variables from "Automatic" to "Automatic Variables". Added text
3330 clarifying the scope of automatic variables.
3332 2002-10-04 Paul D. Smith <psmith@gnu.org>
3334 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3335 as () braces.
3336 (record_files): Ditto.
3338 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3339 the search for the '=' to only within the enclosing parens.
3341 2002-10-03 Paul D. Smith <psmith@gnu.org>
3343 Version 3.80 released.
3345 * dir.c: Change hash functions to use K&R function definition style.
3346 * function.c: Ditto.
3347 * read.c: Ditto.
3348 * variable.c: Ditto.
3350 Update to automake 1.7.
3352 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3353 (pdf): Remove this target as automake now provides one.
3355 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3357 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3359 * makefile.com: Updates for GNU make 3.80.
3360 * makefile.vms: Ditto.
3362 2002-09-23 Paul D. Smith <psmith@gnu.org>
3364 * read.c (enum make_word_type): Remove w_comment.
3365 (get_next_mword): Don't treat comment characters as special; where
3366 this function is used we will never see a comment (it's stripped
3367 before we get here) and treating comments specially means that
3368 targets like "foo\#bar" aren't handled properly.
3370 2002-09-18 Paul D. Smith <psmith@gnu.org>
3372 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3374 * read.c (eval): Expansion of arguments to export/unexport was
3375 ignoring all arguments after the first one. Change the algorithm
3376 to expand the whole line once, then parse the results.
3378 2002-09-17 Paul D. Smith <psmith@gnu.org>
3380 Fix Bug #940 (plus another bug I found while looking at this):
3382 * read.c (record_target_var): enter_file() will add a new entry if
3383 it's a double-colon target: we don't want to do that in this
3384 situation. Invoke lookup_file() and only enter_file() if it does
3385 not already exist. If the file we get back is a double-colon then
3386 add this variable to the "root" double-colon target.
3388 * variable.c (initialize_file_variables): If this file is a
3389 double-colon target but is not the "root" target, then initialize
3390 the root and make the root's variable list the parent of our
3391 variable list.
3393 2002-09-13 Paul D. Smith <psmith@gnu.org>
3395 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3397 * hash.c (round_up_2): Get rid of a warning.
3399 2002-09-12 Paul D. Smith <psmith@gnu.org>
3401 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3402 so it doesn't complain about getloadavg.c.
3404 * commands.c (set_file_variables): Make sure we always alloca() at
3405 least 1 character for the value of $? (for '\0').
3407 2002-09-11 Paul D. Smith <psmith@gnu.org>
3409 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3410 macro to use RESULT instead of the incorrect _RESULT_.
3412 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3413 and atomic_readdir(). We need to #include dirent.h to get this to
3414 work.
3415 * misc.c (atomic_readdir): Fix typos.
3417 2002-09-10 Paul D. Smith <psmith@gnu.org>
3419 * read.c (eval): Expand variable lists given to export and
3420 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3421 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3423 * doc/make.texi (Variables/Recursion): Document this.
3424 (Conditional Syntax): And here.
3426 2002-09-09 Paul D. Smith <psmith@gnu.org>
3428 * configure.in: Check for memmove().
3430 2002-09-07 Paul D. Smith <psmith@gnu.org>
3432 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3433 Michael Sterrett <msterret@coat.com> reports that while it has
3434 SA_RESTART, it does not work properly.
3436 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3437 that invokes stat() and loops to do it again if it returns EINTR.
3438 (atomic_readdir): Ditto, with readdir().
3440 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3441 and readdir() to atomic_stat() and atomic_readdir().
3443 2002-09-04 Paul D. Smith <psmith@gnu.org>
3445 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3446 reports that GNU make sometimes doesn't recognize that targets can
3447 be made, when directories can be created as prerequisites. He
3448 reports that changing the order of predicates in the DEP->changed
3449 flag test so that lookup_file() is always performed, solves this
3450 problem.
3452 2002-08-08 Paul D. Smith <psmith@gnu.org>
3454 * configure.in: Require a newer version of gettext.
3456 * misc.c (perror_with_name): Translate the format string (for
3457 right-to-left language support).
3458 (pfatal_with_name): Ditto.
3460 * main.c: Create a static array of strings to store the usage
3461 text. This is done to facilitate translations.
3462 (struct command_switch): Remove argdesc and description fields.
3463 (switches): Remove values for obsolete fields.
3464 (print_usage): Print each element of the usage array.
3466 * hash.c: Change function definitions to be K&R style.
3468 2002-08-02 Paul D. Smith <psmith@gnu.org>
3470 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3471 this one because it's too hard to get right. We'll look at it for
3472 a future release.
3473 * main.c (main): Don't create the .TARGETS variable.
3474 * variable.c (handle_special_var): Don't handle .TARGETS.
3476 2002-08-01 Paul D. Smith <psmith@gnu.org>
3478 * main.c (switches): Add a new option, -B (--always-make). If
3479 specified, make will rebuild all targets that it encounters even
3480 if they don't appear to be out of date.
3481 (always_make_flag): New flag.
3482 * make.h: Extern always_make_flag.
3483 * remake.c (update_file_1): Check always_make_flag; if it's set we
3484 will always rebuild any target we can, even if none of its
3485 prerequisites are newer.
3486 * NEWS: Mention it.
3488 * doc/make.texi (Shell Function): Make it clear that make
3489 variables marked as "export" are not passed to instances of the
3490 shell function.
3492 Add new introspection variable .VARIABLES and .TARGETS.
3494 * variable.c (handle_special_var): New function. If the variable
3495 reference passed in is "special" (.VARIABLES or .TARGETS),
3496 calculate the new value if necessary. .VARIABLES is handled here:
3497 walk through the hash of defined variables and construct a value
3498 which is a list of the names. .TARGETS is handled by
3499 build_target_list().
3500 (lookup_variable): Invoke handle_special_var().
3501 * file.c (build_target_list): Walk through the hask of known files
3502 and construct a list of the names of all the ones marked as
3503 targets.
3504 * main.c (main): Initialize them to empty (and as simple variables).
3505 * doc/make.texi (Special Variables): Document them.
3506 * NEWS: Mention them.
3508 * variable.h (struct variable): Add a new flag "exportable" which
3509 is true if the variable name is valid for export.
3510 * variable.c (define_variable_in_set): Set "exportable" when a new
3511 variable is defined.
3512 (target_environment): Use the "exportable" flag instead of
3513 re-checking the name here... an efficiency improvement.
3515 2002-07-31 Paul D. Smith <psmith@gnu.org>
3517 * config.h-vms.template: Updates to build on VMS. Thanks to
3518 Brian_Benning@aksteel.com for helping verify the build.
3519 * makefile.com: Build the new hash.c file.
3520 * hash.h: Use strcpmi(), not stricmp(), in the
3521 HAVE_CASE_INSENSITIVE_FS case.
3523 2002-07-30 Paul D. Smith <psmith@gnu.org>
3525 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3526 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3527 Reported by <Brian_Benning@aksteel.com>.
3529 2002-07-10 Paul D. Smith <psmith@gnu.org>
3531 * variable.c (pop_variable_scope): Remove variable made unused by
3532 new hash infrastructure.
3533 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3534 comparisons as well as name comparisons.
3535 * variable.h: Add a prototype for new hash_init_function_table().
3536 * file.c (lookup_file): Remove variables made unused by new hash
3537 infrastructure.
3538 * dir.c (directory_contents_hash_2): Missing return of hash value.
3539 (dir_contents_file_exists_p): Remove variables made unused by new
3540 hash infrastructure.
3543 Installed Greg McGary's integration of the hash functions from the
3544 GNU id-utils package:
3546 2002-07-10 Greg McGary <greg@mcgary.org>
3548 * scripts/functions/filter-out: Add literals to to the
3549 pattern space in order to add complexity, and trigger
3550 use of an internal hash table. Fix documentation strings.
3551 * scripts/targets/INTERMEDIATE: Reverse order of files
3552 passed to expected `rm' command.
3554 2002-07-10 Greg McGary <greg@mcgary.org>
3556 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

3610 Use new hash table package.

3613 (struct a_pattern): New struct.
3614 (func_filter_filterout): Pass through patterns noting boundaries
3615 and '%', if present. Note a_word length. Use a hash table if
3616 arglists are large enough to justify cost.
3617 (function_table_init): Renamed from function_table.

3646 2002-07-10 Paul D. Smith <psmith@gnu.org>
3648 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3649 prerequisite list. A real SysV make will expand the entire
3650 prerequisites list _twice_: we don't do that as it's a big
3651 backward-compatibility problem. We only replace those specific
3652 variables.
3654 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3655 references left in the list of prerequisites. Check for .POSIX as
3656 we record targets, so we can disable non-POSIX behavior while
3657 reading makefiles as well as running them.
3658 (eval): Check the prerequisite list to see if we have anything
3659 that looks like a SysV prerequisite variable reference.
3661 2002-07-09 Paul D. Smith <psmith@gnu.org>
3663 * doc/make.texi (Prerequisite Types): Add a new section describing
3664 order-only prerequisites.
3666 * read.c (uniquize_deps): If we have the same file as both a
3667 normal and order-only prereq, get rid of the order-only prereq,
3668 since the normal one supersedes it.
3670 2002-07-08 Paul D. Smith <psmith@gnu.org>
3672 * AUTHORS: Added Greg McGary to the AUTHORS file.
3673 * NEWS: Blurbed order-only prerequisites.
3674 * file.c (print_file): Show order-only deps properly when printing
3675 the database.
3677 * maintMakefile: Add "update" targets for wget'ing the latest
3678 versions of various external files. Taken from Makefile.maint in
3679 autoconf, etc.
3681 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3682 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3684 2002-07-07 Paul D. Smith <psmith@gnu.org>
3686 * po/*.po: Remove. We'll use wget to retrieve them at release
3687 time.
3689 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3690 rather than a shell you get an exception. Make sure we look up
3691 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3693 * remake.c (notice_finished_file): Fix handling of -t flag.
3694 Patch provided by Henning Makholm <henning@makholm.net>.
3696 * implicit.c (pattern_search): Some systems apparently run short
3697 of stack space, and using alloca() in this function caused an
3698 overrun. I modified it to use xmalloc() on the two variables
3699 which seemed like they might get large. Fixes Bug #476.
3701 * main.c (print_version): Update copyright notice to conform with
3702 GNU standards.
3703 (print_usage): Update help output.
3705 * function.c (func_eval): Create a new make function, $(eval
3706 ...). Expand the arguments, put them into a buffer, then invoke
3707 eval_buffer() on the resulting string.
3708 (func_quote): Create a new function, $(quote VARNAME). Inserts
3709 the value of the variable VARNAME without expanding it any
3710 further.
3712 * read.c (struct ebuffer): Change the linebuffer structure to an
3713 "eval buffer", which can be either a file or a buffer.
3714 (eval_makefile): Move the code in the old read_makefile() which
3715 located a makefile into here: create a struct ebuffer with that
3716 information. Have it invoke the new function eval() with that
3717 ebuffer.
3718 (eval_buffer): Create a new function that creates a struct ebuffer
3719 that holds a string buffer instead of a file. Have it invoke
3720 eval() with that ebuffer.
3721 (eval): New function that contains the guts of the old
3722 read_makefile() function: this function parses makefiles. Obtains
3723 data to parse from the provided ebuffer. Some modifications to
3724 make the flow of the function cleaner and clearer. Still could
3725 use some work here...
3726 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3727 contents of the define/endef variable from the ebuffer.
3728 (readstring): Read the next line from a string-style ebuffer.
3729 (readline): Read the next line from an ebuffer. If it's a string
3730 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3731 from the file.
3733 * dep.h (eval_buffer): Prototype eval_buffer();
3735 * variable.c (do_variable_definition): Make sure that all
3736 non-target-specific variables are registered in the global set.
3737 If we're invoked from an $(eval ...) we might be inside a $(call
3738 ...) or other function which has pushed a variable scope; we still
3739 want to define our variables from evaluated makefile code in the
3740 global scope.
3742 2002-07-03 Greg McGary <greg@mcgary.org>
3744 * dep.h (struct dep) [ignore_mtime]: New member.
3745 [changed]: convert to a bitfield.
3746 * implicit.c (pattern_search): Zero ignore_mtime.
3747 * main.c (main, handle_non_switch_argument): Likewise.
3748 * rule.c (convert_suffix_rule): Likewise.
3749 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3750 (read_makefile): Parse '|' in prerequisite list.
3751 (uniquize_deps): Consider ignore_mtime when comparing deps.
3752 * remake.c (update_file_1, check_dep): Don't force remake for
3753 dependencies that have d->ignore_mtime.
3754 * commands.c (FILE_LIST_SEPARATOR): New constant.
3755 (set_file_variables): Don't include a
3756 prerequisite in $+, $^ or $? if d->ignore_mtime.
3757 Define $|.
3759 2002-06-18 Paul D. Smith <psmith@gnu.org>
3761 * make.texinfo: Updates for next revision. New date/rev/etc.
3762 Recreate all Info menus. Change license on the manual to the GNU
3763 Free Documentation License. A number of typos.
3764 (Variables Simplify): Don't use "-" before it's defined.
3765 (Automatic Prerequisites): Rewrite the target example to work
3766 properly if the compile fails. Remove incorrect comments about
3767 how "set -e" behaves.
3768 (Text Functions): Move the "word", "wordlist", "words", and
3769 "firstword" functions here, from "File Name Functions".
3770 * make-stds.texi: Update from latest GNU version.
3771 * fdl.texi: (created) Import the latest GNU version.
3773 2002-06-06 Paul D. Smith <psmith@gnu.org>
3775 * variable.c (do_variable_definition): New function: extract the
3776 part of try_variable_definition() that actually sets the value
3777 into a separate function.
3778 (try_variable_definition): Call do_variable_definition() after
3779 parsing the variable definition string.
3780 (define_variable_in_set): Make the name argument const.
3782 * variable.h (enum variable_flavor): Make public.
3783 (do_variable_definition): Create prototype.
3785 * read.c (read_all_makefiles): Create a new built-in variable,
3786 MAKEFILE_LIST.
3787 (read_makefile): Add each makefile read in to this variable value.
3789 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3791 * Makefile.DOS.template: Tweak according to changes in the
3792 distribution. Add back the dependencies of *.o files.
3794 * configh.dos.template: Synchronize with config.h.in.
3796 2002-05-09 Paul D. Smith <psmith@gnu.org>
3798 * file.c (file_timestamp_now): Use K&R function declaration.
3800 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3801 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3802 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3803 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3804 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3805 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3806 nlist.n_name is a pointer rather than an array.
3808 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3809 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3810 * configure.in: Use it instead of the old version.
3812 * main.c (main): Prefer setvbuf() to setlinebuf().
3814 2002-05-08 Paul D. Smith <psmith@gnu.org>
3816 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3817 (loadavg_LDADD): Ditto.
3819 2002-04-29 Paul D. Smith <psmith@gnu.org>
3821 * expand.c (recursively_expand_for_file): Rename
3822 recursively_expand() to recursively_expand_for_file() and provide
3823 an extra argument, struct file. If the argument is provided, set
3824 the variable scope to that of the file before expanding.
3825 * variable.h (recursively_expand): Make this a macro that invokes
3826 recursively_expand_for_file() with a NULL file pointer.
3827 * variable.c (target_environment): Call the renamed function and
3828 provide the current file context.
3829 Fixes Debian bug #144306.
3831 2002-04-28 Paul D. Smith <psmith@gnu.org>
3833 Allow $(call ...) user-defined variables to be self-referencing
3834 without throwing an error. Allows implementation of transitive
3835 closures, among other possibly useful things.
3836 Requested by: Philip Guenther <guenther@sendmail.com>
3838 * variable.h (struct variable): Add a new field: exp_count, and
3839 new macros to hold its size and maximum value.
3840 (warn_undefined): Make this a macro.
3841 * variable.c (define_variable_in_set): Initialize it.
3842 * expand.c (recursively_expand): If we detect recursive expansion
3843 of a variable, check the exp_count field. If it's greater than 0
3844 allow the recursion and decrement the count.
3845 (warn_undefined): Remove this (now a macro in variable.h).
3846 * function.c (func_call): Before we expand the user-defined
3847 function, modify its exp_count field to contain the maximum
3848 number of recursive calls we'll allow. After the call, reset it
3849 to 0.
3851 2002-04-21 Paul D. Smith <psmith@gnu.org>
3853 Modified to use latest autoconf (2.53), automake (1.6.1), and
3854 gettext (0.11.1). We're using gettext's new "external" support,
3855 to avoid including libintl source with GNU make.
3857 * README.cvs: New file. Explain how to build GNU make from CVS.
3859 * configure.in: Modify checking for the system glob library.
3860 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3861 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3862 etc. will manage it correctly). Set an automake conditional
3863 USE_LOCAL_GLOB to decide whether to compile the glob library.
3865 * getloadavg.c (main): Include make.h in the "TEST" program to
3866 avoid warnings.
3868 * Makefile.am: Remove special rules for loadavg. Replace them
3869 with Automake capabilities for building extra programs.
3871 * signame.c: This file does nothing if the system provide
3872 strsignal(). If not, it implements strsignal(). If the system
3873 doesn't define sys_siglist, then we make our own; otherwise we use
3874 the system version.
3875 * signame.h: Removed.
3877 * main.c (main): No need to invoke signame_init(). Update copyright.
3879 * ABOUT-NLS: Removed.
3880 * gettext.c: Removed.
3881 * gettext.h: Get a simplified copy from the gettext package.
3882 * po/*: Created.
3883 * i18n/*.po: Moved to po/.
3884 * i18n/: Removed.
3886 * config/*: Created. Contains package configuration helper files.
3887 * config.guess, config.sub: Moved to config directory.
3889 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3890 Rework to use new-style autoconf features. Use the "external"
3891 mode for gettext. Make the build.sh config file conditional on
3892 whether build.sh.in exists, to avoid autoconf errors.
3893 * acinclude.m4: Removed almost all macros as being obsolete.
3894 Rewrote remaining macros to use AC_DEFINE.
3895 * acconfig.h: Removed.
3897 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3898 conditional to handle customs support. Remove special handling
3899 for i18n features.
3901 2002-04-20 Paul D. Smith <psmith@gnu.org>
3903 * function.c (func_call): Don't mark the argument variables $1,
3904 etc. as recursive. They've already been fully expanded so
3905 there's no need to do it again, and doing so strips escaped $'s.
3906 Reported by Sebastian Glita <glseba@yahoo.com>.
3908 * remake.c (notice_finished_file): Walk through double-colon
3909 entries via the prev field, not the next field!
3910 Reported by Greg McGary <greg@mcgary.org>.
3912 * main.c (main): If the user specifies -q and asks for a specific
3913 target which is a makefile, we got an assert. In that case it
3914 turns out we should continue normally instead.
3916 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3918 * i18n/he.po: Installed a new translation.
3920 2002-01-07 Paul D. Smith <psmith@gnu.org>
3922 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3924 2001-12-04 Paul D. Smith <psmith@gnu.org>
3926 * i18n/ja.po: Installed an updated translation.
3928 2001-09-06 Paul Eggert <eggert@twinsun.com>
3930 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3931 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3933 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3934 are available.
3935 (main): Get rid of any avoidable limit on stack size.
3937 2001-09-04 Paul D. Smith <psmith@gnu.org>
3939 * i18n/da.po: Installed an updated translation.
3941 2001-08-03 Paul D. Smith <psmith@gnu.org>
3943 * i18n/fr.po: Installed an updated translation.
3944 Resolves Debian bug #106720.
3946 2001-06-13 Paul D. Smith <psmith@gnu.org>
3948 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3949 translation.
3951 2001-06-11 Paul D. Smith <psmith@gnu.org>
3953 * i18n/ko.po: Installed a new translation.
3955 2001-05-06 Paul D. Smith <psmith@gnu.org>
3957 Modify the EINTR handling.
3959 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3960 the way in which we manage the file descriptor/signal handler race
3961 trap to be more efficient.
3963 2001-05-06 Paul Eggert <eggert@twinsun.com>
3965 Restart almost all system calls that are interrupted, instead
3966 of worrying about EINTR. The lone exception is the read() for
3967 job tokens.
3969 * configure.in (HAVE_SA_RESTART): New macro.
3970 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3971 * main.c (main): Use SA_RESTART instead of the old,
3972 nonstandard SA_INTERRUPT.
3974 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3975 * main.c (bsd_signal): New function or macro,
3976 if the implementation doesn't supply it.
3977 (The bsd_signal function will be in POSIX 1003.1-200x.)
3978 (HANDLESIG): Remove.
3979 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3981 * make.h (EINTR_SET): Remove.
3982 (SA_RESTART): New macro.
3984 * arscan.c (ar_member_touch): Don't worry about EINTR.
3985 * function.c (func_shell): Likewise.
3986 * job.c (reap_children, free_child, new_job): Likewise.
3987 * main.c (main): Likewise.
3988 * remake.c (touch_file, name_mtime): Likewise.
3990 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3991 if fstat failed with errno!=EINTR, the error was ignored.
3993 * job.c (set_child_handler_action_flags): New function.
3994 (new_job): Use it to temporarily clear the SIGCHLD action flags
3995 while reading the token.
3997 2001-05-02 Paul D. Smith <psmith@gnu.org>
3999 * job.c (start_job_command): Don't add define/endef per-line flags
4000 to the top-level flags setting.
4002 2001-04-03 Paul D. Smith <psmith@gnu.org>
4004 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4005 bit on error, so check for odd return values, not non-0 return
4006 values.
4007 (VMS_get_member_info): Calculate the timezone differences correctly.
4008 Reported by John Fowler <jfowler@nyx.net>.
4011 2001-03-14 Paul D. Smith <psmith@gnu.org>
4013 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4014 value before invoking define_variable().
4015 Reported by John Fowler <jfowler@nyx.net>.
4017 2001-02-07 Paul D. Smith <psmith@gnu.org>
4019 * read.c (record_target_var): If we reset the variable due to a
4020 command-line variable setting overriding it, turn off the "append"
4021 flag.
4023 2001-01-17 Paul D. Smith <psmith@gnu.org>
4025 * variable.c (lookup_variable) [VMS]: When getting values from the
4026 environment, allocate enough space for the _value_ plus escapes,
4027 not enough space for the name plus escapes :-/.
4028 Reported by John Fowler <jfowler@nyx.net>.
4030 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4031 warnings that make generates, so it doesn't look like an error.
4032 Reported by Karl Berry <karl@gnu.org>.
4035 Fix for PR/2020: Rework appended target-specific variables. I'm
4036 fairly confident this algorithm is finally correct.
4038 * expand.c (allocated_variable_append): Rewrite. Instead of
4039 expanding each appended variable then adding all the expanded
4040 strings together, we append all the unexpanded values going up
4041 through the variable set contexts, then expand the final result.
4042 This behaves just like non-target-specific appended variable
4043 values, while the old way didn't in various corner cases.
4044 (variable_append): New function: recursively append the unexpanded
4045 value of a variable, walking from the outermost variable scope to
4046 the innermost.
4047 * variable.c (lookup_variable): Remove the code that looked up the
4048 variable set list if the found variable was "append". We don't
4049 need this anymore.
4050 (lookup_variable_in_set): Make this non-static so we can use it
4051 elsewhere.
4052 (try_variable_definition): Use lookup_variable_in_set() rather
4053 than faking out current_variable_set_list by hand (cleanup).
4054 * variable.h: Add a prototype for the now non-static
4055 lookup_variable_in_set().

4059 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4060 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4061 before throwing a fit.
4063 2000-11-17 Paul D. Smith <psmith@gnu.org>
4065 * read.c (readline): CRLF calculations had a hole, if you hit the
4066 buffer grow scenario just right. Reworked the algorithm to avoid
4067 the need for len or lastlen at all. Problem description with
4068 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4070 2000-10-24 Paul D. Smith <psmith@gnu.org>
4072 * gettext.c (SWAP): Declare this with the prototype, otherwise
4073 some systems don't work (non-32-bit? Reported for Cray T3E).
4074 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4076 2000-10-05 Paul D. Smith <psmith@gnu.org>
4078 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4079 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4081 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4083 2000-09-22 Paul D. Smith <psmith@gnu.org>
4085 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4086 parts of the real gettext.h here, and we expect to really include
4087 the real gettext.h later. If we keep this #define, it's ignored.
4089 2000-09-21 Paul D. Smith <psmith@gnu.org>
4091 * main.c (log_working_directory): Rework the text to use complete
4092 sentences, to make life simpler for the translators.
4094 2000-08-29 Paul D. Smith <psmith@gnu.org>
4096 * file.c (remove_intermediates): Print a debug message before we
4097 remove intermediate files, so the user (if she uses -d) knows
4098 what's going on.
4100 2000-08-21 Paul D. Smith <psmith@gnu.org>
4102 * variable.c (try_variable_definition): Change how we handle
4103 target-specific append variable defns: instead of just setting the
4104 value, expand it as an append _but_ only within the current
4105 target's context. Otherwise we lose all but the last value if the
4106 variable is appended more than once within the current target
4107 context. Fixes PR/1831.
4109 2000-08-16 Paul D. Smith <psmith@gnu.org>
4111 * function.c (func_shell): Nul-terminate the buffer before
4112 printing an exec error message (just in case it's not!).
4113 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4115 2000-07-25 Paul D. Smith <psmith@gnu.org>
4117 * job.c (construct_command_argv_internal): Add "~" to the list of
4118 sh_chars[] which disallow optimizing out the shell call.
4120 2000-07-23 Paul Eggert <eggert@twinsun.com>
4122 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4123 supersedes --disable-nsec-timestamps.
4124 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4125 * README: Remove --disable-nsec-timestamps.
4127 * filedef.h (struct file.low_resolution_time): New member.
4128 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4129 * remake.c (update_file_1):
4130 Avoid spurious rebuilds due to low resolution time stamps,
4131 generalizing the earlier code that applied only to archive members.
4132 (f_mtime): Archive members always have low resolution time stamps.
4134 * configure.in: Remove --disable-nsec-timestamps, as this has
4135 been superseded by .LOW_RESOLUTION_TIME.
4137 2000-07-23 Paul Eggert <eggert@twinsun.com>
4139 * configure.in (enable_nsec_timestamps): Renamed from
4140 make_cv_nsec_timestamps, since enable/disable options
4141 shouldn't be cached.
4143 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4144 and Paul Eggert <eggert@twinsun.com>
4146 * file.c (file_timestamp_now):
4147 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4148 so that clock_gettime is not linked unless needed.
4150 * filedef.h (FILE_TIMESTAMP_HI_RES):
4151 Remove definition; "configure" now does this.
4153 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4154 to before high resolution file timestamp check,
4155 since that check now uses uintmax_t.
4156 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4157 high resolution file timestamps.
4158 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4159 so that we don't link in clock_gettime unnecessarily.
4161 2000-07-17 Paul D. Smith <psmith@gnu.org>
4163 * i18n/ja.po: New version of the translation file.
4165 2000-07-07 Paul D. Smith <psmith@gnu.org>
4167 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4168 the offset calculation.
4169 (name_mtime): Replace EINTR test with EINTR_SET macro.
4171 2000-07-07 Paul Eggert <eggert@twinsun.com>
4173 Fix for PR/1811:
4175 * remake.c (update_file_1):
4176 Avoid spurious rebuilds of archive members due to their
4177 timestamp resolution being only one second.
4178 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4179 the clock's resolution being lower than file timestamps'.
4180 When warning about future timestamps, report only the discrepancy,
4181 not the absolute value of the timestamp and the current time.
4183 * file.c (file_timestamp_now): New arg RESOLUTION.
4184 * filedef.h (file_timestamp_now): Likewise.
4185 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4187 2000-07-05 Paul D. Smith <psmith@gnu.org>
4189 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4190 to listp. Fixes PR/1793.
4192 2000-06-26 Paul Eggert <eggert@twinsun.com>
4194 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4196 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4198 * remake.c (f_mtime): Remove unused var memtime.
4200 2000-06-25 Martin Buchholz <martin@xemacs.org>
4202 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4203 Ran spell-check on make.texinfo.
4205 2000-06-23 Paul D. Smith <psmith@gnu.org>
4207 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4208 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4209 * make.h: Define these macros.
4211 * Version 3.79.1 released.
4213 * configure.in: Add a new option, --disable-nsec-timestamps, to
4214 avoid using sub-second timestamps on systems that support it. It
4215 can lead to problems, e.g. if your makefile relies on "cp -p".
4216 * README.template: Document the issue with "cp -p".
4218 * config.guess, config.sub: Updated.
