1 2011-09-02 Paul Smith <psmith@gnu.org>
3 * remake.c (touch_file): If we have both -n and -t, -n takes
4 precedence. Patch from Michael Witten <mfwitten@gmail.com>
6 2011-08-29 Paul Smith <psmith@gnu.org>
8 * expand.c (variable_expand_string): Always allocate a new buffer
9 for a string we're expanding. The string we're working on can get
10 freed while we work on it (for example if it's the value of a
11 variable which modifies itself using an eval operation).
12 See Savannah patch #7534 for the original report by Lubomir Rintel.
14 2011-06-12 Paul Smith <psmith@gnu.org>
16 * read.c (parse_file_seq): Move the check for empty members out of
17 the loop so we can go to the next member properly.
18 Another fix for Savannah bug #30612.
20 * config.h-vms.template: Newer versions of VMS have strncasecmp()
21 Patch provided by: Hartmut Becker <becker.ismaning@freenet.de>
23 2011-05-07 Paul Smith <psmith@gnu.org>

26 whether this is the first invocation or not. If it's not and
27 private_var is set, then skip this variable and try the next one.
28 Fixes Savannah bug #32872.
30 * read.c (parse_file_seq): Ensure existence checks use glob().
32 2011-05-07 Eli Zaretskii <eliz@gnu.org>
34 * job.c (construct_command_argv_internal): Don't assume shellflags
35 is always non-NULL. Escape-protect characters special to the
36 shell when copying the value of SHELL into new_line. Fixes
37 Savannah bug #23922.
39 2011-05-02 Paul Smith <psmith@gnu.org>

73 value, then send it to the shell and store the result.
74 (parse_variable_definition): Parse "!=" shell assignments.
75 * read.c (get_next_mword): Treat "!=" as a varassign word.

83 * strcache.c (various): Increase performance based on comments
84 from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>. Stop looking for
85 a buffer when we find the first one that fits, not the best fit.
86 If there is not enough free space in a buffer move it to a
87 separate list so we don't have to walk it again.
88 * make.h (NDEBUG): Turn off asserts unless maintainer mode is set.

532 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
533 not struct file (a file can be a dependency of many targets,
534 some don't care, some do).
536 * remake.c (update_goal_chain): Propagate DONTCARE from struct
537 dep to struct file before updating the goal and restore it
538 afterwards.
539 (update_file): Don't prune the dependency graph if this target
540 has failed but the diagnostics hasn't been issued.
541 (complain): Scan the file's dependency graph to find the file
542 that caused the failure.
543 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
544 whether to print diagnostics.
546 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
548 2009-09-28 Paul Smith <psmith@gnu.org>
550 * doc/make.texi (Pattern Intro): Move the match algorithm
551 discussion into the "Pattern Match" node.
552 (Pattern Match): Expand on the pattern rule matching algorithm.
554 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
556 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
557 much of the command line on a single pass.
559 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
561 * varible.c (create_pattern_var): Insert variables into the
562 PATTERN_VARS list in the shortest patterns first order.
564 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
565 used to sort the rules.
566 (stemlen_compare): Compare two tryrule elements.
567 (pattern_search): Sort the rules so that they are in the shortest
568 stem first order.
570 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
572 * doc/make.texi (Pattern-specific Variable Values): Describe the
573 new pattern-specific variables application order.
574 (Introduction to Pattern Rules): Describe the new pattern rules
575 search order.
577 * NEWS: Add a note about the new behavior.
579 2009-09-27 Paul Smith <psmith@gnu.org>
581 * doc/make.texi (Double-Colon): Mention that pattern rules with
582 double-colons have a different meaning. Savannah bug #27497.
584 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
586 * configh.dos.template: Remove unconditional definition of
587 SYS_SIGLIST_DECLARED.
588 Include <sys/version.h> because ports of GCC 4.3.0 and later no
589 longer include it, so macros like __DJGPP_MINOR__ are no longer
590 defined automatically.
592 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
593 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
594 instead of using the hardcoded ones.
595 (SUBDIRS): doc subdir added.
596 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
597 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
598 create html formated docs. texi2html may not be ported to DOS.
599 (make.info, make.dvi, make.ps, make.html): Make targets depend on
600 'make.texi'.
601 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
602 -I switch to look in ./ instead of ./doc.
603 (html): Target depend on html-recursive instead of make_1.html.
604 (make_1.html): Removed.
605 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
606 (all-recursive): Allow for more than one subdir in the build
607 process.
608 (mostlyclean-recursive, clean-recursive, distclean-recursive)
609 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
610 (tags-recursive): Allow for more than one subdir in the build
611 process.
612 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
613 targets. Enter into doc/ to produce the targets.
614 (all-am): $(INFO_DEPS) replaced by info.
616 2009-09-26 Paul Smith <psmith@gnu.org>
618 * read.c (record_files): Use free_ns() to free struct nameseq.
619 (eval): Ditto.
621 * rule.c (freerule): Use free_dep_chain().
623 * read.c (record_files): Free FILENAMES chain for implicit rules.
624 (eval): Static pattern targets go into the string cache.
626 * function.c (string_glob): Free NAME in the nameseq chain.
628 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
630 * implicit.c (pattern_search): Terminate early if we haven't
631 found any rules to try (performance improvement).
633 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
635 * implicit.c (pattern_search): Merge three parallel arrays,
636 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
637 of struct TRYRULE. In the old version the latter two arrays
638 had insufficient length.
640 2009-09-24 Paul Smith <psmith@gnu.org>
642 * implicit.c (pattern_search): Add back support for order-only
643 prerequisites for secondary expansion implicit rules, that were
644 accidentally dropped. If we find a "|", enable order-only mode
645 and set IGNORE_MTIME on all deps that are seen afterward.
646 (pattern_search): Fix memory leaks: for intermediate files where
647 we've already set the file variable and pattern variable sets, be
648 sure to either save or free them as appropriate.
650 2009-09-23 Paul Smith <psmith@gnu.org>
652 Rework the way secondary expansion is stored, for efficiency.
653 This changes secondary expansion so that ONLY WHEN we know we have
654 a possibility of needing secondary expansion, do we defer the
655 secondary expansion. This means more parsing the deps but we use
656 a lot less memory (due to the strcache). Also, this fixes
657 Savannah bug #18622.
659 * read.c (eval): Don't parse the dep string here anymore.
660 (record_files): Take the dep argument as an unparsed string. If
661 secondary expansion is enabled AND the prereq string has a '$' in
662 it, then set NEED_2ND_EXPANSION and keep the entire string.
663 Otherwise, parse the dep string here to construct the dep list
664 with the names in the strcache.
666 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
667 duplicate the name string (others are in the strcache).
669 * implicit.c: Remove struct idep and free_idep_chain(): unused.
670 (struct patdeps): New structure to store prereq information.
671 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
672 which prerequisites need expansion, and expand only those.
674 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
675 and enter_prereqs(). split_prereqs() takes a fully-expanded string
676 and splits it into a DEP list, handling order-only prereqs.
677 (enter_prereqs): This function enters a list of DEPs into the file
678 database. If there's a stem defined, expand any pattern chars.
679 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
680 set. Use the above functions.
681 (snap_deps): Only perform second expansion on prereqs that need it,
682 as defined by the NEED_2ND_EXPANSION flag.
683 (print_prereqs): New function to print the prereqs
684 (print_file): Call print_prereqs() rather than print inline.
686 * hash.h (STRING_COMPARE): Take advantage of strcache() by
687 comparing pointers.
688 (STRING_N_COMPARE): Ditto.
689 (ISTRING_COMPARE): Ditto.
691 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
692 (parse_file_seq): Return void*
693 * read.c (parse_file_seq): Return void*.
694 (eval): Invoke macroized version of parse_file_seq()
695 * default.c (set_default_suffixes): Ditto.
696 * file.c (split_prereqs): Ditto.
697 * function.c (string_glob): Ditto.
698 * main.c (main): Ditto.
699 * rule.c (install_pattern_rule): Ditto.
701 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
703 2009-09-16 Paul Smith <psmith@gnu.org>
705 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
706 convert to macros.
707 * dep.h: Create alloc_dep() / free_dep() macros.
709 * implicit.c (pattern_search): Take advantage of the new
710 parse_file_seq() to add the directory prefix to each prereq.
712 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
713 all. Avoid reversing chains. Support adding prefixes.
714 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
715 cached/non-cached results.
716 (eval): Remove multi_glob() & invoke new parse_file_seq().
717 * rule.c (install_pattern_rule): Ditto.
718 * main.c (main): Ditto.
719 * implicit.c (pattern_search): Ditto.
720 * function.c (string_glob): Ditto.
721 * file.c (parse_prereqs): Ditto.
722 * default.c (set_default_suffixes): Ditto.
724 * variable.c (parse_variable_definition): Don't run off the end of
725 the string if it ends in whitespace (found with valgrind).
727 * commands.c (set_file_variables): Keep space for all targets in
728 $? if -B is given (found with valgrind).
730 2009-09-15 Paul Smith <psmith@gnu.org>
732 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
733 (xcalloc): Add new function.
734 * make.h: New declarations.
736 * ar.c (ar_glob_match): New calling method for concat().
737 * main.c (main): Ditto.
738 (decode_env_switches): Ditto.
739 * read.c (eval_makefile): Ditto.
740 (tilde_expand): Ditto.
741 (parse_file_seq): Ditto.
742 * variable.c (target_environment): Ditto.
743 (sync_Path_environment): Ditto.
745 * ar.c (ar_glob_match): Use xcalloc().
746 * dir.c (file_impossible): Ditto.
747 * file.c (enter_file): Ditto.
748 * job.c (new_job): Ditto.
749 * read.c (parse_file_seq): Ditto.
750 * vmsfunctions.c (opendir): Ditto.
752 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
754 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
755 inside the loop that looks up environment for PATH.
757 2009-08-31 Eli Zaretskii <eliz@gnu.org>
759 * function.c (windows32_openpipe): Update envp after calling
760 sync_Path_environment.
762 2009-08-02 Paul Smith <psmith@gnu.org>
764 * remake.c (notice_finished_file): Ensure file->cmds is not null
765 before looping through them. Fixes Savannah bug #21824.
767 * doc/make.texi (Wildcard Examples): Clarify when objects is
768 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
769 (Include): Clarify the behavior of -include.
770 Fixes Savannah bug #18963.
772 2009-08-01 Paul Smith <psmith@gnu.org>
774 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
775 etc. come on the command line. Fixes Savannah bug #27093.
777 * expand.c (expand_argument): If the argument is large enough use
778 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
780 * variable.c (do_variable_definition): Avoid using alloca() to
781 hold values, which can be large. Fixes Savannah bug #23960.
783 * job.c (new_job): Use memmove() instead of strcpy() since both
784 pointers are in the same memory block. Fixes Savannah bug #27148.
785 Patch by Petr Machata.
787 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
789 * job.c (construct_command_argv_internal): Add "ulimit" and
790 "unset" to the sh_cmds for Unixy shells.
792 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
794 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
795 that set make_cv_sys_gnu_glob, so they are also correctly set
796 when the cache has been populated before.
798 2009-07-04 Eli Zaretskii <eliz@gnu.org>
800 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
801 exist, as realpath(3) does where it's supported.
803 2006-07-04 Eli Zaretskii <eliz@gnu.org>
805 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
806 (abspath): Support systems that define HAVE_DOS_PATHS (have
807 drive letters in their file names). Use IS_PATHSEP instead of a
808 literal '/' comparison. Fixes Savannah bug #26886.
810 2009-06-14 Paul Smith <psmith@gnu.org>
812 * remake.c (update_file_1): Remember the original file we marked
813 as updating, so we can clear that flag again. If we find a target
814 via vpath, FILE might change.
815 (check_dep): Ditto. Fixes Savannah bug #13529.
816 Patch by Reid Madsen <reid.madsen@tek.com>.
818 2009-06-13 Paul Smith <psmith@gnu.org>
820 * doc/make.texi (MAKEFILES Variable): Be explicit that files
821 included by MAKEFILES cannot give default goals.
822 * read.c (eval): If set_default is not set, pass the no-default-goal
823 value when we read included makefiles. Fixes Savannah bug #13401.
825 * ar.c (ar_name): Ensure that targets with empty parens aren't
826 considered archive member references: archive members must have a
827 non-empty "member" string. Fixes Savannah bug #18435.
829 * function.c (string_glob): Rely on multi_glob() to determine
830 whether files exist or not. Remove call to file_exists_p() which
831 is not always correct. Fixes Savannah bug #21231.
832 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
833 then only files that really exist will be returned.
834 * dep.h: Add new argument to multi_glob().
835 * rule.c (install_pattern_rule): Ditto.
836 * read.c (eval): Ditto.
837 * main.c (main): Ditto.
838 * implicit.c (pattern_search): Ditto.
839 * file.c (parse_prereqs): Ditto.
840 * default.c (set_default_suffixes): Ditto.
842 2009-06-09 Paul Smith <psmith@gnu.org>
844 * commands.c (set_file_variables): If always_make_flag is set,
845 always add the prereq to $?. Fixes Savannah bug #17825.
847 * remake.c (update_file_1): When rebuilding deps of FILE, also try
848 to rebuild the deps of all the also_make targets for that file.
849 Fixes Savannah bug #19108.
851 * implicit.c (pattern_search): Undo test for is_target, added by
852 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
853 Rule Search Algorithm". Fixes Savannah bug #17752.
855 * main.c (clean_jobserver): Clear the jobserver_fds options and
856 set job_slots to the default when we clean up.
857 (define_makeflags): Return the new MAKEFLAGS value.
858 (main): Reset MAKEFLAGS in the environment when we re-exec.
859 Fixes Savannah bug #18124.
861 2009-06-08 Paul Smith <psmith@gnu.org>
863 * read.c (eval): Collapse continuations post-semicolon on target-
864 specific variables. Fixes Savannah bug #17521.
866 2009-06-07 Paul Smith <psmith@gnu.org>
868 * job.c (reap_children): For older systems without waitpid() (are
869 there any of these left?) run wait(2) inside EINTRLOOP to handle
870 EINTR errors. Fixes Savannah bug #16401.
872 * (various): Debug message cleanup. Fixes Savannah bug #16469.
874 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
876 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
877 not the end, to catch second expansion $(eval ...) defining new
878 target/prereq relationships during snap_deps.
879 Fixes Savannah bug #24622.
881 * read.c (record_files): The second-expansion "f->updating" hack
882 was not completely correct: if assumed that the target with
883 commands always had prerequisites; if one didn't then the ordering
884 was messed up. Fixed for now to use f->updating to decide whether
885 to preserve the last element in the deps list... but this whole
886 area of constructing and reversing the deps list is too confusing
887 and needs to be reworked. Fixes Savannah bug #21198.
889 2009-06-06 Paul Smith <psmith@gnu.org>
891 * hash.c (hash_insert): Remove useless test for NULL.
892 Fixes Savannah bug #21823.
894 * make.h: Move SET_STACK_SIZE determination to make.h.
895 * main.c (main): New global variable, STACK_LIMIT, holds the
896 original stack limit when make was started.
897 * job.c (start_job_command): Reset the stack limit, if we changed it.
898 Fixes Savannah bug #22010.
900 * remake.c (check_dep): Only set the target's state to not-started
901 if it's not already running. Found this while testing -j10 builds
902 of glibc: various targets were being rebuilt multiple times.
903 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
904 bug #15919.
906 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
907 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
908 Bugzilla bug 10246.
910 2009-06-04 Paul Smith <psmith@gnu.org>
912 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
914 * maintMakefile: Modify access of config and gnulib Savannah
915 modules to use GIT instead of CVS.
917 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
918 Fixes Savannah bug #24655.
920 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
921 this can happen during some invocations of $(eval ...) for example.
922 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
924 2009-06-02 Paul Smith <psmith@gnu.org>
926 * configure.in: Check for fileno()
927 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
928 for the makefile file so invocations of $(shell ...) don't inherit it.
929 Fixes Savannah bug #24277.
931 2009-06-01 Paul Smith <psmith@gnu.org>
933 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
934 expansion was handled incorrectly. Rework the default goal
935 handling to save the variable only. Remove default_goal_file and
936 default_goal_name.
937 * read.c (eval): Check default_goal_var, not default_goal_name.
938 * read.c (record_target_var): Don't check default_goal_file here.
940 2009-05-31 Paul Smith <psmith@gnu.org>
942 * main.c (main): Expand the .DEFAULT_GOAL variable before using
943 it, and if the multi_glob() returns nothing (say it expanded to
944 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
946 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
947 $(and ..) to the reference. Fixes Savannah bug #25694.
949 * make.1: Be clear that some recipes will be executed even with -n.
950 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
952 * doc/make.texi (Override Directive): Make more clear how
953 overrides and appends interact.
954 Elucidates part of Savannah bug #26207.
956 * read.c (record_target_var): Don't reset the origin on
957 target-specific variables; try_variable_definition() will handle
958 this correctly. Fixes Savannah bug #26207.
960 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
961 Fixes Savannah bug #25712.
963 * implicit.c (pattern_search): Keep a pointer to the beginning of
964 the filename and save that instead of the constructed pointer.
965 Fixes Savannah bug #26593.
966 Patch by Mark Seaborn <mrs@mythic-beasts.com>
968 2009-05-30 Paul Smith <psmith@gnu.org>
970 * doc/make.texi (Multi-Line): Add a description of the new abilities
971 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
972 "command sequence" vs. "recipe" syntax.
973 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
974 after a define, to create variables with those flavors.
976 2009-05-25 Paul Smith <psmith@gnu.org>
978 Reworked the parser for variable assignments to allow multiple
979 modifiers, and in any order. Also allows variable and
980 prerequisites to be modifier names ('export', 'private', etc.)
982 * NEWS: Add notes about user-visible changes.
984 * read.c (struct vmodifiers): Remember what modifiers were seen.
985 (parse_var_assignment): New function to parse variable assignments.
986 (eval): Call the new function. Handle variable assignments earlier.
988 * variable.c (parse_variable_definition): Only parse; don't create var.
989 (assign_variable_definition): Call parse, then create the var.
991 2009-05-24 Paul Smith <psmith@gnu.org>
993 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
994 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
996 2009-03-14 Eli Zaretskii <eliz@gnu.org>
998 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
999 Fixes Savannah bug #25412.
1001 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1002 prototype for xmalloc.
1003 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1004 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1005 Loop over an array of extensions, instead of duplicating the same
1006 code inline. Use SearchPath followed by CreateFile, instead of
1007 the obsolete OpenFile. Fixes Savannah bug #17277.
1008 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1009 to `find_file'. Fixes Savannah bug #25662.
1011 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1013 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1014 Fixes Savannah bug #20495.
1016 2009-02-28 Ralf Wildenhues <address@hidden>
1018 * doc/make.texi (Instead of Execution): Document interaction of
1019 -t with phony targets.
1021 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1023 Introduce a new keyword "private" which applies to target-specific
1024 variables and prevents their values from being inherited.
1026 * variable.h (struct variable): Add private_var flag to each variable.
1027 Add a flag to specify which list entry switches to the parent target.
1028 * variable.c (define_variable_in_set): Initialize private_var flag.
1029 (lookup_variable): Skip private variables in parent contexts.
1030 (initialize_file_variables): Set next_is_parent appropriately.
1031 (print_variable): Show the private_var flag.

1036 2008-10-26 Paul Smith <psmith@gnu.org>
1038 * configure.in: Check for strndup().
1039 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
1040 if it's available.
1041 * make.h: Rename savestring to xstrndup.
1042 * commands.c (chop_commands): Ditto.
1043 * function.c (func_foreach): Ditto.

1110 HAVE_DECL_SYS_SIGLIST.
1112 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1113 build does not use child_execute_job.
1115 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1116 export the SHELL environment variable to the child.
1118 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1142 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1143 a more complex value than a simple shell: if it's not a default

1146 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1148 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1149 pathnames, with const strings.
1150 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1153 2007-10-10 Paul Smith <psmith@gnu.org>
1155 * make.h: Add a prototype for w32_kill() (change suggested by

1178 (Rule Syntax): Ditto.
1179 (Command Syntax): Ditto.
1180 (Error Messages): Ditto.
1182 2007-09-10 Paul Smith <psmith@gnu.org>
1184 * commands.c (print_commands): Don't print an extra line in the
1185 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1187 * read.c (construct_include_path): Add the full string to the cache; we
1188 were chopping the last char.
1190 * NEWS: Announce the .RECIPEPREFIX special variable.
1191 * variable.c (lookup_special_var): Rename from handle_special_var().
1192 (lookup_variable): Call the new name.

1197 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1198 * main.c (main): Create the .RECIPEPREFIX special variable.
1199 * read.c (eval): Remove the cmd_prefix characters from the command
1200 scripts here, so they're not stored in the commands array at all,
1201 rather than waiting and stripping them out during command construction.
1202 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1204 2007-08-15 Paul Smith <psmith@gnu.org>
1206 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1207 file has had the section info removed, so add some to make.texi
1208 before we include it.
1210 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1212 * remake.c (check_dep): Reset the target state for intermediate
1213 files. They might have been considered before but not updated

1228 2007-07-13 Paul Smith <psmith@gnu.org>
1230 * file.c (expand_deps): Use variable_buffer as the start of the

1232 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1233 Fixes Savannah bug #20452.
1235 2007-07-04 Paul Smith <psmith@gnu.org>
1237 * (ALL FILES): Update to GPLv3.

1248 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1249 "Expansion of a deferred"
1250 Fixes Savannah bug #20018.
1252 * expand.c (variable_expand_for_file): Preserve the value of

1256 2007-05-11 Paul Smith <psmith@gnu.org>
1258 * job.c (new_job): Add debug info to specify where make found the
1259 command script it is running to build a target.
1260 Fixes Savannah bug #18617.

1263 Add support for Objective C. Fixes Savannah bug #16389.
1264 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1266 * function.c (func_lastword): Initialize p.
1268 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1269 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1270 Dave Korn <dave.korn@artimi.com>
1272 2007-05-08 Paul Smith <psmith@gnu.org>
1274 Fix Savannah bug #19656:
1276 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1278 * make.h: Change all case-insensitive string compares to use
1279 strcasecmp() (from POSIX). If we don't have that but do have one
1280 of the others, define strcasecmp to be one of those instead. If
1281 we don't have any, declare a prototype for our own version.
1283 * misc.c (strcasecmp): Use this if we can't find any native
1284 case-insensitive string comparison function.
1285 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1286 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1287 strcmpi().
1288 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1289 strcasecmp() instead of stricmp().
1290 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1291 instead of strcmpi().
1292 * acinclude.m4: Remove the strcasecmp() check from here.
1294 2007-03-21 Paul Smith <psmith@gnu.org>
1296 * configure.in: Don't turn on case-insensitive file system support
1297 if --disable-... is given. Fixes Savannah bug #19348.
1299 2007-03-19 Paul Smith <psmith@gnu.org>
1301 * ALL: Use the strcache for all file name strings, or other
1302 strings which we will never free. The goal is to save memory by
1303 avoiding duplicate copies of strings. However, at the moment this
1304 doesn't save much memory in most situations: due to secondary
1305 expansion we actually save prerequisite lists twice (once before
1306 the secondary expansion, and then again after it's been parsed
1307 into individual file names in the dep list). We will resolve this
1308 in a future change, by doing the parsing up-front for targets
1309 where secondary expansion is not set.
1311 Moving things into the strcache also allows us to use const
1312 pointers in many more places.
1314 2007-01-03 Paul Smith <psmith@gnu.org>
1316 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1317 the function, not just the first. Fixes Savannah bug #18680.
1319 2006-11-18 Paul Smith <psmith@gnu.org>
1321 * strcache.c (strcache_add_len): Don't allocate a new buffer
1322 unless the string is not already nil-terminated. Technically this
1323 is a violation of the standard, since we may be passed an array
1324 that is not long enough to test one past. However, in make this
1325 is never true since we only use nil-terminated strings or
1326 sub-strings thereof.
1328 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1330 * main.c: New global cmd_prefix, defaults to '\t'.
1331 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1332 of '\t'.
1334 * dir.c: Constified.
1335 (dir_contents_file_exists_p): Check for an error return from
1336 readdir(), just in case.
1338 * commands.c: Constified.
1339 * default.c: Constified.
1340 * expand.c: Constified.
1341 * function.c: Partial constification.
1342 * variable.c: Partial constification.
1343 * vmsify.c: Constification. Hard to test this but I hope I didn't
1344 screw it up!
1345 * vpath.c: Partial constification.
1346 * w32/pathstuff.c: Partial constification.
1348 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1350 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1351 backslashes and drive letters as absolute.
1353 2006-10-22 Paul Smith <psmith@gnu.org>
1355 * main.c (struct command_switch): Use const and void*.
1357 2006-10-21 Paul Smith <psmith@gnu.org>
1359 * ar.c: Constified.
1360 * arscan.c: Constified.
1362 2006-09-30 Paul Smith <psmith@gnu.org>
1364 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1365 point to lastword since the example was updated.
1366 Fixes Savannah bug #16304.
1367 (Secondary Expansion): Correct example description.
1368 Fixes Savannah bug #16468.
1369 (Makefile Contents): Clarify that comments cannot appear within
1370 variable references or function calls.
1371 Fixes Savannah bug #16577.
1372 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1373 Fixes Savannah bug #17701.
1374 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1375 (Prerequisite Types): Added an example of using order-only
1376 prerequisites. Fixes Savannah bug #17880.
1377 (Rule Syntax): "lise" -> "list"
1378 (Multiple Rules): ... -> @dots{}
1379 (Splitting Lines): ditto.
1381 * remake.c (update_file_1): Prereqs that don't exist should be
1382 considered changed, for the purposes of $?.
1383 Fixes Savannah bug #16051.
1385 * make.1: Remove extraneous "+".
1386 Fixes Savannah bug #16652.
1388 2006-09-06 Paul D. Smith <psmith@gnu.org>

1395 $PATH_SEPARATOR.
1397 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1398 Normally, it is defined in config.h.

1401 well.
1403 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1404 sh_chars_sh for Windows platforms that emulate Unix.
1406 2006-05-07 Paul D. Smith <psmith@gnu.org>

1432 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1433 inner-scope variables don't mask outer-scope variables.
1435 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1436 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1437 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1438 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1439 values from memory allocation functions: they return void* and so
1440 don't need to be cast. Also remove (char *) casts of arguments to
1441 xrealloc().
1443 * configure.in: Remove checks for memcpy/memmove/strchr.
1445 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

1451 * variable.c, vpath.c: Ditto.
1453 * make.h (EXIT_FAILURE): Should be 1, not 0.
1455 2006-04-06 Paul D. Smith <psmith@gnu.org>

1486 support from automake, as described in the Texinfo manual.
1488 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1490 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1491 with lastslash, since the latter points to filename, not to
1492 target.
1493 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1494 Declare and define sh_chars_sh[].
1496 2006-03-23 Paul D. Smith <psmith@gnu.org>
1498 * configure.in: Look for build.sh.in in $srcdir so it will be
1499 built for remote configurations as well.

1502 Fixes Savannah bug #16166.
1504 * misc.c (log_access): Takes a const char *.

1553 expanding the result, we expand (or not, if it's simple) each part
1554 as we add it.
1555 (allocated_variable_append): Don't expand the final result.
1556 Fixes Savannah bug #15913.
1558 2006-03-09 Paul Smith <psmith@gnu.org>
1560 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1561 listed non-existent files as changed. Turns out there's a bug in
1562 the Linux kernel builds which means that this change causes
1563 everything to rebuild every time. We will re-introduce this fix
1564 in the next release, to give them time to fix their build system.
1565 Fixes Savannah bug #16002.
1566 Introduces Savannah bug #16051.
1568 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1569 we *don't* find UNIX "/".
1570 Reported by David Ergo <david.ergo@alterface.com>
1572 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1574 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1575 locator function find_and_set_default_shell if SHELL came from the
1576 command line.
1578 2006-02-20 Paul D. Smith <psmith@gnu.org>
1580 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1581 to be null; don't core in that case.
1583 2006-02-19 Paul D. Smith <psmith@gnu.org>
1585 * commands.c (set_file_variables): Realloc, not malloc, the static
1586 string values to avoid memory leaks.
1588 * expand.c (recursively_expand_for_file): Only set reading_file to
1589 an initialized value.
1591 * implicit.c (pattern_search): We need to make a copy of the stem
1592 if we get it from an intermediate dep, since those get freed.
1594 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1595 begin with ".".
1596 (enter_file) [VMS]: Ditto.
1597 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1599 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1601 * job.c (construct_command_argv_internal): Fix last change.
1603 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1604 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1605 the calls to _beginthreadex.
1607 * expand.c (recursively_expand_for_file): Initialize `save' to
1608 prevent compiler warnings.
1610 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1612 * job.c (construct_command_argv_internal): Don't create a temporary
1613 script/batch file if we are under -n. Call _setmode to switch the
1614 script file stream to text mode.
1616 2006-02-17 Paul D. Smith <psmith@gnu.org>
1618 * variable.c (merge_variable_set_lists): Don't try to merge the
1619 global_setlist. Not only is this useless, but it can lead to
1620 circularities in the linked list, if global_setlist->next in one
1621 list gets set to point to another list which also ends in
1622 global_setlist.
1623 Fixes Savannah bug #15757.
1625 2006-02-15 Paul D. Smith <psmith@gnu.org>
1627 Fix for Savannah bug #106.
1629 * expand.c (expanding_var): Keep track of which variable we're
1630 expanding. If no variable is being expanded, it's the same as
1631 reading_file.
1632 * make.h (expanding_var): Declare it.
1633 * expand.c (recursively_expand_for_file): Set expanding_var to the
1634 current variable we're expanding, unless there's no file info in
1635 it (could happen if it comes from the command line or a default
1636 variable). Restore it before we exit.
1637 * expand.c (variable_expand_string): Use the expanding_var file
1638 info instead of the reading_file info.
1639 * function.c (check_numeric): Ditto.
1640 (func_word): Ditto.
1641 (func_wordlist): Ditto.
1642 (func_error): Ditto.
1643 (expand_builtin_function): Ditto.
1644 (handle_function): Ditto.
1646 2006-02-14 Paul D. Smith <psmith@gnu.org>
1648 * read.c (eval): Even if the included filenames expands to the
1649 empty string we still need to free the allocated buffer.
1651 * implicit.c (pattern_search): If we allocated a variable set for
1652 an impossible file, free it.
1653 * variable.c (free_variable_set): New function.
1654 * variable.h: Declare it.
1656 * read.c (read_all_makefiles): Makefile names are kept in the
1657 strcache, so there's never any need to alloc/free them.
1658 (eval): Ditto.
1660 * main.c (main): Add "archives" to the .FEATURES variable if
1661 archive support is enabled.
1662 * doc/make.texi (Special Variables): Document it.
1664 2006-02-13 Paul D. Smith <psmith@gnu.org>
1666 * implicit.c (pattern_search): Add checking for DOS pathnames to
1667 the pattern rule target LASTSLASH manipulation.
1668 Fixes Savannah bug #11183.
1670 2006-02-11 Paul D. Smith <psmith@gnu.org>
1672 * (ALL FILES): Updated copyright and license notices.
1674 2006-02-10 Paul D. Smith <psmith@gnu.org>
1676 A new internal capability: the string cache is a read-only cache
1677 of strings, with a hash table interface for fast lookup. Nothing
1678 in the cache will ever be freed, so there's no need for reference
1679 counting, etc. This is the beginning of a full solution for
1680 Savannah bug #15182, but for now we only store makefile names here.
1682 * strcache.c: New file. Implement a read-only string cache.
1683 * make.h: Add prototypes for new functions.
1684 * main.c (initialize_global_hash_tables): Initialize the string cache.
1685 (print_data_base): Print string cache stats.
1686 * read.c (eval_makefile): Use the string cache to store makefile
1687 names. Rewrite the string allocation to be sure we free everything.
1689 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1691 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1692 directory time stamp didn't change, except on FAT filesystems.
1693 Suggested by J. David Bryan <jdbryan@acm.org>.
1695 2006-02-09 Paul D. Smith <psmith@gnu.org>
1697 * function.c (func_or): Implement a short-circuiting OR function.
1698 (func_and): Implement a short-circuiting AND function.
1699 (function_table_init): Update the table with the new functions.
1700 * doc/make.texi (Conditional Functions): Changed the "if" section
1701 to one on general conditional functions. Added documentation for
1702 $(and ...) and $(or ...) functions.
1703 * NEWS: Note new $(and ...) and $(or ...) functions.
1705 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1707 * job.h (struct child): Add the dontcare bitfield.
1708 * job.c (new_job): Cache dontcare flag.
1709 * job.c (reap_children): Use cached dontcare flag instead of the
1710 one in struct file. Fixes Savannah bug #15641.
1712 2006-02-06 Paul D. Smith <psmith@gnu.org>
1714 * vpath.c (selective_vpath_search): If the file we find has a
1715 timestamp from -o or -W, use that instead of the real time.
1716 * remake.c (f_mtime): If the mtime is a special token from -o or
1717 -W, don't overwrite it with the real mtime.
1718 Fixes Savannah bug #15341.
1720 Updates from Markus Mauhart <qwe123@chello.at>:
1722 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1723 (process_signal, process_last_err, process_exit_code): Manage
1724 invalid handle values.
1725 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1726 manage invalid handles; remove them.
1727 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1728 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1729 * README.cvs: Updates for building from CVS.
1731 2006-02-05 Paul D. Smith <psmith@gnu.org>
1733 * file.c (enter_file): Keep track of the last double_colon entry,
1734 to avoid walking the list every time we want to add a new one.
1735 Fixes Savannah bug #15533.
1736 * filedef.h (struct file): Add a new LAST pointer.
1738 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1739 the comparison. For 64-bits systems the result of the subtraction
1740 might not fit into an int. Use comparison instead.
1741 Fixes Savannah bug #15534.
1743 * doc/make.texi: Update the chapter on writing commands to reflect
1744 the changes made in 3.81 for backslash/newline and SHELL handling.
1746 2006-02-01 Paul D. Smith <psmith@gnu.org>
1748 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1749 variable st is not used when it's not initialized.
1750 Patch from Eli Zaretskii <eliz@gnu.org>.
1752 2006-01-31 Paul D. Smith <psmith@gnu.org>
1754 * README.W32.template: Applied patch #4785 from
1755 Markus Mauhart <qwe123@chello.at>.
1756 * README.cvs: Applied patch #4786 from
1757 Markus Mauhart <qwe123@chello.at>.
1758 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1759 J. Grant <jg@jguk.org>.
1761 * main.c: Update the copyright year in the version output.
1762 * prepare_w32.bat: Remove this file from the distribution.
1764 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1766 * remake.c (update_goal_chain): Set g->changed instead of
1767 incrementing it, as it is only 8-bit wide, and could overflow if
1768 many commands got started in update_file.
1770 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1772 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1773 MAXIMUM_WAIT_OBJECTS.
1774 (process_wait_for_any_private): Change dimension of handles[]
1775 array to MAXIMUM_WAIT_OBJECTS.
1776 (process_used_slots): New function.
1777 (process_register): Don't register more processes than the
1778 available number of slots.
1779 (process_easy): Don't start new processes if all slots are used up.
1781 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1782 are already more children than sub_proc.c can handle, behave as if
1783 the load were too high.
1784 (start_job_command): Fix a typo in error message when process_easy
1785 fails.
1787 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1789 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1790 the shell is not sh.exe.
1792 * job.c (create_batch_file): Renamed from create_batch_filename;
1793 all callers changed. Don't close the temporary file; return its
1794 file descriptor instead. New arg FD allows to return the file
1795 descriptor.
1796 (construct_command_argv_internal): Use _fdopen instead of fopen to
1797 open the batch file.
1799 2006-01-04 Paul D. Smith <psmith@gnu.org>
1801 * readme.vms: Updates for case-insensitive VMS file systems from
1802 Hartmut Becker <Hartmut.Becker@hp.com>.
1803 * dir.c (vms_hash): Ditto.
1804 * vmsify.c (copyto): Ditto.
1805 * vmsfunctions.c (readdir): Ditto.
1807 * make.1: Add a section on the exit codes for make.
1809 * doc/make.texi: A number of minor updates to the documentation.
1811 2006-01-03 Paul D. Smith <psmith@gnu.org>
1813 * remake.c (update_file_1): Mark a prerequisite changed if it
1814 doesn't exist.
1816 * read.c (eval): Be sure to strip off trailing whitespace from the
1817 prerequisites list properly. Also, initialize all fields in
1818 struct dep when creating a new one.
1820 2005-12-28 Paul D. Smith <psmith@gnu.org>
1822 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1823 disable warnings for MSC.
1824 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1826 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1828 * doc/make.texi (Execution): Add a footnote about changes in
1829 handling of backslash-newline sequences. Mention the differences
1830 on MS-DOS and MS-Windows.
1832 * NEWS: More details about building the MinGW port and a pointer
1833 to README.W32. Fix the section name that describes the new
1834 backward-incompatible processing of backslash-newline sequences.
1835 The special processing of SHELL set to "cmd" is only relevant to
1836 MS-Windows, not MS-DOS.
1838 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1840 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1841 to DWORD, to avoid compiler warnings.
1842 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1843 use %ld in format, to avoid compiler warnings.
1845 * doc/make.texi (Special Targets): Fix a typo.
1846 (Appending): Fix cross-reference to Setting.
1847 (Special Variables, Secondary Expansion, File Name Functions)
1848 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1849 periods after a sentence.
1850 (Execution): Add @: after "e.g.".
1851 (Environment): Fix punctuation.
1852 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1853 (Shell Function, Target-specific): Add @: after "vs."
1855 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1857 * read.c (record_target_var): Initialize variable's export field
1858 with v_default instead of leaving it "initialized" by whatever
1859 garbage happened to be on the heap.
1861 2005-12-12 Paul D. Smith <psmith@gnu.org>
1863 * make.1: Fix some display errors and document all existing options.
1864 Patch by Mike Frysinger <vapier@gentoo.org>.
1866 2005-12-11 Paul D. Smith <psmith@gnu.org>
1868 * implicit.c (pattern_search): If 2nd expansion is not set for
1869 this implicit rule, replace the pattern with the stem directly,
1870 and don't re-expand the variable list. Along with the other
1871 .SECONDEXPANSION changes below, fixes bug #13781.
1873 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1875 * implicit.c (pattern_search): Mark other files that this rule
1876 builds as targets so that they are not treated as intermediates
1877 by the pattern rule search algorithm. Fixes bug #13022.
1879 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1881 * remake.c (notice_finished_file): Propagate the change of
1882 modification time to all the double-colon entries only if
1883 it is the last one to be updated. Fixes bug #14334.
1885 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1887 * function.c (func_flavor): Implement the flavor function which
1888 returns the flavor of a variable.
1889 * doc/make.texi (Functions for Transforming Text): Document it.
1890 * NEWS: Add it to the list of new functions.
1892 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1894 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1895 variable.
1896 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1897 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1899 2005-10-26 Paul Smith <psmith@gnu.org>
1901 * read.c (record_files): Don't set deps flags if there are no deps.
1902 * maintMakefile: We only need to build the templates when we are
1903 creating a distribution, so don't do it for "all".
1905 2005-10-24 Paul D. Smith <psmith@gnu.org>
1907 Make secondary expansion optional: its enabled by declaring the
1908 special target .SECONDEXPANSION.
1910 * NEWS: Update information on second expansion capabilities.
1911 * doc/make.texi (Secondary Expansion): Document the
1912 .SECONDEXPANSION special target and its behavior.

1914 prerequisite list was found in a static pattern rule.
1915 (free_dep_chain): Declare a prototype.
1916 * file.c (parse_prereqs): New function: break out some complexity
1917 from expand_deps().
1918 (expand_deps): If we aren't doing second expansion, replace % with
1919 the stem for static pattern rules. Call the new function.
1920 * filedef.h (parse_prereqs): Declare a prototype.
1921 * implicit.c (pattern_search): Initialize the new staticpattern
1922 field.
1923 * main.c (second_expansion): Declare a global variable to remember
1924 if the special target has been seen. Initialize the new
1925 staticpattern field for prerequisites.
1926 * make.h: Extern for second_expansion.
1927 * misc.c (free_dep_chain): New function: frees a struct dep list.
1928 * read.c (read_all_makefiles): Initialize the staticpattern field.
1929 (eval_makefile): Ditto.
1930 (record_files): Check for the .SECONDEXPANSION target and set
1931 second_expansion global if it's found.
1932 Use the new free_dep_chain() instead of doing it by hand.
1933 Set the staticpattern field for prereqs of static pattern targets.
1935 2005-10-16 Paul D. Smith <psmith@gnu.org>
1937 * main.c (main): Set CURDIR to be a file variable instead of a
1938 default, so that values of CURDIR inherited from the environment
1939 won't override the make value.
1941 2005-09-26 Paul D. Smith <psmith@gnu.org>
1943 * job.c (construct_command_argv_internal): If the line is empty
1944 remember to free the temporary argv strings.
1945 Fixes bug # 14527.
1947 2005-09-16 Paul D. Smith <psmith@gnu.org>
1949 * job.c (start_job_command): The noerror flag is a boolean (single
1950 bit); set it appropriately.
1951 Reported by Mark Eichin <eichin@metacarta.com>
1953 2005-08-29 Paul D. Smith <psmith@gnu.org>
1955 * function.c (func_error): On Windows, output from $(info ...)
1956 seems to come in the wrong order. Try to force it with fflush().
1958 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1960 * read.c (record_files): Move code that sets stem for static
1961 pattern rules out of the if (!two_colon) condition so it is
1962 also executed for two-colon rules. Fixes Savannah bug #13881.
1964 2005-08-08 Paul D. Smith <psmith@gnu.org>
1966 * make.h: Don't test that __STDC__ is non-0. Some compilers
1967 (Windows for example) set it to 0 to denote "ISO C + extensions".
1968 Fixes bug # 13594.
1970 2005-08-07 Paul D. Smith <psmith@gnu.org>
1972 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1973 conditional (slightly different version of a fix from Eli).
1975 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1976 If make is running in parallel without -k and two jobs die in a
1977 row, but not too close to each other, then make will quit without
1978 waiting for the rest of the jobs to die.
1980 * main.c (die): Don't reset err before calling reap_children() the
1981 second time: we still want it to be in the error condition.
1982 * job.c (reap_children): Use a static variable, rather than err,
1983 to control whether or not the error message should be printed.
1985 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1987 * w32/subproc/sub_proc.c: Include signal.h.
1988 (process_pipe_io, process_file_io): Pass a pointer to a local
1989 DWORD variable to GetExitCodeProcess. If the exit code is
1990 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1992 * job.c [WINDOWS32]: Include windows.h.
1993 (main_thread) [WINDOWS32]: New global variable.
1994 (reap_children) [WINDOWS32]: Get the handle for the main thread
1995 and store it in main_thread.
1997 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1998 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1999 doing anything else. When we are done, close the main thread
2000 handle and exit with status 130.
2002 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2004 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2005 pointer to fprintf.
2007 * main.c (find_and_set_default_shell): If found a DOSish shell,
2008 set sh_found and the value of default_shell, and report the
2009 findings in debug mode.
2011 * job.c (construct_command_argv_internal): Check unixy_shell, not
2012 no_default_sh_exe, to decide whether to use Unixy or DOSish
2013 builtin commands.
2015 * README.W32: Update with info about the MinGW build.
2017 * build_w32.bat: Support MinGW.
2019 * w32/subproc/build.bat: Likewise.
2021 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2022 printing DWORD args.
2024 * function.c (windows32_openpipe): Fix format strings for printing
2025 DWORD args.
2027 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2028 'reap_mode'.
2029 (start_job_command): Fix format string for printing the result of
2030 process_easy.
2031 (start_job_command) [WINDOWS32]: Do not define.
2032 (exec_command): Fix format string for printing HANDLE args.
2034 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2035 to avoid compiler warnings.
2036 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2037 (Note: some of these fixes were submitted independently by J. Grant)
2039 2005-07-30 J. Grant <jg@jguk.org>
2041 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2042 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2043 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2045 2005-07-15 Paul Smith <psmith@gnu.org>
2047 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2048 we don't have a POSIX shell, then revert to the old
2049 backslash-newline behavior (where they are stripped).
2050 Fixes bug #13665.
2052 2005-07-08 Paul D. Smith <psmith@gnu.org>
2054 * config.h.W32.template: Reorder to match the standard config.h,
2055 for easier comparisons.
2056 From J. Grant <jg@jguk.org>
2058 * maintMakefile: Remove .dep_segment before overwriting it, in
2059 case it's not writable or noclobber is set.
2060 * expand.c (variable_expand_string): Cast result of pointer
2061 arithmetic to avoid a warning.
2062 * main.c (switches): Add full-fledged final initializer.
2064 2005-07-06 Paul D. Smith <psmith@gnu.org>
2066 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2067 * signame.c (strsignal): If we found _sys_siglist[] or
2068 __sys_siglist[] use those instead of sys_siglist[].
2069 From Albert Chin <china@thewrittenword.com>
2071 2005-07-04 Paul D. Smith <psmith@gnu.org>
2073 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2074 globfree(); set up to use the GNU versions.
2075 From Martin Zinser <zinser@zinser.no-ip.info>
2077 2005-07-03 Paul D. Smith <psmith@gnu.org>
2079 From J. Grant <jg@jguk.org>:
2081 * README.W32.template: Update the Windows and tested MSVC versions.
2082 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2083 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2084 * build_w32.bat: Ditto.
2085 * w32/subproc/build.bat: Ditto.
2087 2005-06-28 Paul D. Smith <psmith@gnu.org>
2089 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2090 declaration was checked but not present.
2092 2005-06-27 Paul D. Smith <psmith@gnu.org>
2094 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2095 to unsigned long. Fixes Savannah bug #13550.
2097 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2098 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2099 Fixes Savannah bug #13551.
2101 2005-06-26 Paul D. Smith <psmith@gnu.org>
2103 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2104 it if ANSI_STRING is not set.
2106 2005-06-25 Paul D. Smith <psmith@gnu.org>
2108 * read.c (eval): If no filenames are passed to any of the
2109 "include" variants, don't print an error.
2110 * doc/make.texi (Include): Document this.
2111 Fixes Savannah bug #1761.
2113 * job.c (construct_command_argv_internal): Sanitize handling of
2114 backslash/newline pairs according to POSIX: that is, keep the
2115 backslash-newline in the command script, but remove a following
2116 TAB character, if present. In the fast path, make sure that the
2117 behavior matches what the shell would do both inside and outside
2118 of quotes. In the slow path, quote the backslash and put a
2119 literal newline in the string.
2120 Fixes Savannah bug #1332.
2121 * doc/make.texi (Execution): Document the new behavior and give
2122 some examples.
2123 * NEWS: Make a note of the new behavior.
2125 * make.h [WINDOWS32]: #include <direct.h>.
2126 Fixes Savannah bug #13478.
2128 * remake.c (name_mtime): If the stat() of a file fails and the -L
2129 option was given and the file is a symlink, take the best mtime of
2130 the symlink we can get as the mtime of the file and don't fail.
2131 Fixes Savannah bug #13280.
2133 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2134 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2135 inside a variable reference. Make this function static as it's
2136 only used here.
2137 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2138 parsing an unexpanded line looking for semicolons.
2139 Fixes Savannah bug #1454.
2140 * misc.c (remove_comments): Move this to read.c and make it static
2141 as it's only used there. Call find_char_unquote() with new arg.
2142 * make.h: Remove prototypes for find_char_unquote() and
2143 remove_comments() since they're static now.
2145 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2146 its export flag and obtain its value. When we need to re-exec,
2147 increment the value and add it into the environment.
2148 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2149 * NEWS: Mention MAKE_RESTARTS.
2150 * main.c (always_make_set): New variable. Change the -B option to
2151 set this one instead.
2152 (main): When checking makefiles, only set always_make_flag if
2153 always_make_set is set AND the restarts flag is 0. When building
2154 normal targets, set it IFF always_make_set is set.
2155 (main): Avoid infinite recursion with -W, too: only set what-if
2156 files to NEW before we check makefiles if we've never restarted
2157 before. If we have restarted, set what-if files to NEW _after_ we
2158 check makefiles.
2159 Fixes Savannah bug #7566:
2161 2005-06-17 Paul D. Smith <psmith@gnu.org>
2163 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2164 in the prerequisites list.
2166 2005-06-12 Paul D. Smith <psmith@gnu.org>
2168 Fix Savannah bug # 1328.
2170 * configure.in: Check for atexit().
2171 * misc.c (close_stdout): Test stdout to see if writes to it have
2172 failed. If so, be sure to exit with a non-0 error code. Based on
2173 code found in gnulib.
2174 * make.h: Prototype.
2175 * main.c (main): Install close_stdout() with atexit().
2177 2005-06-10 Paul D. Smith <psmith@gnu.org>
2179 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2181 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2182 headers; make vmsWaitForChildren() static; extern vmsify().
2183 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2184 Don't create child_execute_job() here (it's in vmsjobs.c).
2185 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2187 2005-06-09 Paul D. Smith <psmith@gnu.org>
2189 * variable.c (push_new_variable_scope): File variables point
2190 directly to the global_setlist variable. So, inserting a new
2191 scope in front of that has no effect on those variables: they
2192 don't go through current_variable_set_list. If we're pushing a
2193 scope and the current scope is global, push it "the other way" so
2194 that the new setlist is in the global_setlist variable, and
2195 next points to a new setlist with the global variable set.
2196 (pop_variable_scope): Properly undo a push with the new
2197 semantics.
2198 Fixes Savannah bug #11913.
2200 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2202 * job.c (reap_children): Don't die of the command failed but
2203 the dontcare flag is set. Fixes Savannah bug #13216.
2205 * implicit.c (pattern_search): When creating a target from
2206 an implicit rule match, lookup pattern target and set precious
2207 flag in a newly created target. Fixes Savannah bug #13218.
2209 2005-05-13 Paul D. Smith <psmith@gnu.org>
2211 Implement "if... else if... endif" syntax.
2213 * read.c (eval): Push all checks for conditional words ("ifeq",
2214 "else", etc.) down into the conditional_line() function.
2215 (conditional_line): Rework to allow "else if..." clause. New
2216 return value -2 for lines which are not conditionals. The
2217 ignoring flag can now also be 2, which means "already parsed a
2218 true branch". If that value is seen no other branch of this
2219 conditional can be considered true. In the else parsing if there
2220 is extra text after the else, invoke conditional_line()
2221 recursively to see if it's another conditional. If not, it's an
2222 error. If so, raise the conditional value to this level instead
2223 of creating a new conditional nesting level. Special check for
2224 "else" and "endif", which aren't allowed on the "else" line.
2225 * doc/make.texi (Conditional Syntax): Document the new syntax.
2227 2005-05-09 Paul D. Smith <psmith@gnu.org>
2229 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2230 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2231 recurses to the w32 directory, even on non-Windows systems. Use
2232 the method suggested in the automake manual.
2233 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2234 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2236 2005-05-07 Paul D. Smith <psmith@gnu.org>
2238 * main.c (die): If we're dying with a fatal error (not that a
2239 command has failed), write back any leftover tokens before we go.
2241 * job.c (set_child_handler_action_flags): If there are jobs
2242 waiting for the load to go down, set an alarm to go off in 1
2243 second. This allows us to wake up from a potentially long-lasting
2244 read() and start a new job if the load has gone down. Turn it off
2245 after the read.
2246 (job_noop): Dummy signal handler function.
2247 (new_job): Invoke it with the new semantics.
2249 * docs/make.texi: Document secondary expansion. Various cleanups
2250 and random work.
2252 2005-05-03 Paul D. Smith <psmith@gnu.org>
2254 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2255 the targets which are to ultimately be made are called "goals";
2256 see the GNU make manual. Also, MAKECMDGOALS, etc.
2258 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2259 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2260 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2262 2005-05-02 Paul D. Smith <psmith@gnu.org>
2264 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2265 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2266 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2267 functions to vmsjobs.c. #include it into jobs.c.
2269 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2270 jobserver tokens. I found that this happens when an exported
2271 recursive variable contains a $(shell ...) function reference: in
2272 this situation we could "forget" to write back a token.
2274 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2275 we have. It's not reliable to depend on the number of children in
2276 our linked list so keep a separate count.
2277 (new_job): Check jobserver_tokens rather than children &&
2278 waiting_jobs. Increment jobserver_tokens when we get one.
2279 (free_child): If jobserver_tokens is 0, internal error. If it's
2280 >1, write a token back to the jobserver pipe (we don't write a
2281 token for the "free" job). Decrement jobserver_tokens.
2283 * main.c: Add variable master_job_slots.
2284 (main): Set it to hold the number of jobs requested if we're the
2285 master process, when using the jobserver.
2286 (die): Sanity checks: first test jobserver_tokens to make sure
2287 this process isn't holding any tokens we didn't write back.
2288 Second, if master_job_slots is set count the tokens left in the
2289 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2291 2005-04-24 Paul D. Smith <psmith@gnu.org>
2293 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2294 with -l# can lose jobserver tokens, because waiting jobs are not
2295 consulted properly when checking for the "free" token.
2297 * job.c (free_child): Count waiting_jobs as having tokens.
2298 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2299 handle jobs waiting for the load to drop.
2301 2005-04-23 Paul D. Smith <psmith@gnu.org>
2303 * main.c (main): Be careful to not core if a variable setting in
2304 the environment doesn't contain an '='. This is illegal but can
2305 happen in broken setups.
2306 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2308 2005-04-12 Paul D. Smith <psmith@gnu.org>
2310 The second expansion feature causes significant slowdown. Timing
2311 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2312 read the makefile before the feature, to 11+s to do the same
2313 operations after the feature. Additionally, memory usage
2314 increased drastically. To fix this I added some intelligence that
2315 avoids the overhead of the second expansion unless it's required.
2317 * dep.h: Add a new boolean field, need_2nd_expansion.
2319 * read.c (eval): When creating the struct dep for the target,
2320 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2321 (record_files): If there's a "%" in a static pattern rule, it gets
2322 converted to "$*" so set need_2nd_expansion to 1.
2324 * file.c (expand_deps): Rework to be more efficient. Only perform
2325 initialize_file_variables(), set_file_variables(), and
2326 variable_expand_for_file() if the need_2nd_expansion is set.
2328 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2329 (pattern_search): Ditto.
2330 * main.c (handle_non_switch_argument): Ditto.
2331 (main): Ditto.
2332 * read.c (read_all_makefiles): Ditto.
2333 (eval_makefile): Ditto.
2335 2005-04-07 Paul D. Smith <psmith@gnu.org>
2337 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2338 * variable.c (sync_Path_environment): Ditto.
2339 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2341 * main.c (main): Define the .FEATURES variable.
2342 * NEWS: Announce .FEATURES.
2343 * doc/make.texi (Special Variables): Document .FEATURES.
2345 * remake.c (check_dep): If a file is .PHONY, update it even if
2346 it's marked intermediate. Fixes Savannah bug #12331.
2348 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2350 * file.c (expand_deps): Factor out the second expansion and
2351 prerequisite line parsing logic from snap_deps().
2353 * file.c (snap_deps): Use expand_deps(). Expand and parse
2354 prerequisites of the .SUFFIXES special target first. Fixes
2355 Savannah bug #12320.
2357 2005-03-13 Paul D. Smith <psmith@gnu.org>
2359 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2360 Zaretskii.
2362 2005-03-11 Paul D. Smith <psmith@gnu.org>
2364 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2365 available, not undefined (from Earnie Boyd).
2367 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2369 * implicit.c (pattern_search): Mark an intermediate target as
2370 precious if it happened to be a prerequisite of some (other)
2371 target. Fixes Savannah bug #12267.
2373 2005-03-09 Paul D. Smith <psmith@gnu.org>
2375 * read.c (eval_makefile): Add alloca(0).
2376 (eval_buffer): Ditto.
2378 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2380 * main.c (main): Use o_file instead of o_default when defining
2381 the .DEFAULT_TARGET special variable.
2382 * read.c (eval): Use define_variable_global() instead of
2383 define_variable() when setting new value for the .DEFAULT_TARGET
2384 special variable. Fixes Savannah bug #12266.
2386 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2388 * imlicit.c (pattern_search): Mark files for which an implicit
2389 rule has been found as targets. Fixes Savannah bug #12202.
2391 2005-03-04 Paul D. Smith <psmith@gnu.org>
2393 * AUTHORS: Update.
2394 * doc/make.texi (Automatic Variables): Document $|.
2396 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2398 * read.c (record_files): Instead of substituting % with
2399 actual stem value in dependency list replace it with $*.
2400 This fixes stem triple expansion bug.
2402 * implicit.c (pattern_search): Copy stem to a separate
2403 buffer and make it a properly terminated string. Assign
2404 this buffer instead of STEM (which is not terminated) to
2405 f->stem. Instead of substituting % with actual stem value
2406 in dependency list replace it with $*. This fixes stem
2407 triple expansion bug.
2409 2005-03-01 Paul D. Smith <psmith@gnu.org>
2411 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2412 on Windows, as it takes a handle not a pid. Just exit.
2413 Fix from patch #3679, provided by Alessandro Vesely.
2415 * configure.in: Update check for sys_siglist[] from autoconf manual.
2416 * signame.c (strsignal): Update to use the new autoconf macro.
2418 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2420 * read.c (record_files): Add a check for the list of prerequisites
2421 of a static pattern rule being empty. Fixes Savannah bug #12180.
2423 2005-02-28 Paul D. Smith <psmith@gnu.org>
2425 * doc/make.texi (Text Functions): Update docs to allow the end
2426 ordinal for $(wordlist ...) to be 0.
2427 * function.c (func_wordlist): Fail if the start ordinal for
2428 $(wordlist ...) is <1. Matches documentation.
2429 Resolves Savannah support request #103195.
2431 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2432 previously we were stopping when !-q, exactly the opposite. This
2433 has been wrong since version 1.34, in 1994!
2434 (update_file): If we got an error don't break out to run more
2435 double-colon rules: just return immediately.
2436 Fixes Savannah bug #7144.
2438 2005-02-27 Paul D. Smith <psmith@gnu.org>
2440 * misc.c (end_of_token): Make argument const.
2441 * make.h: Update prototype.
2443 * function.c (abspath, func_realpath, func_abspath): Use
2444 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2445 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2446 * read.c (record_files): Ditto.
2447 * variable.c (do_variable_definition): Ditto.
2449 * function.c (func_error): Create a new function $(info ...) that
2450 simply prints the message to stdout with no extras.
2451 (function_table_init): Add new function to the table.
2452 * NEWS: Add $(info ...) reference.
2453 * doc/make.texi (Make Control Functions): Document it.
2455 New feature: if the system supports symbolic links, and the user
2456 provides the -L/--check-symlink-time flag, then use the latest
2457 mtime between the symlink(s) and the target file.
2459 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2460 readlink(). If both are available, define MAKE_SYMLINKS.
2461 * main.c: New variable: check_symlink_flag.
2462 (usage): Add a line for -L/--check-symlink-times to the help string.
2463 (switches): Add -L/--check-symlink-times command line argument.
2464 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2465 print a warning and disable it again.
2466 * make.h: Declare check_symlink_flag.
2467 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2468 if the file is a symlink then check each link in the chain and
2469 choose the NEWEST mtime we find as the mtime for the file. The
2470 newest mtime might be the file itself!
2471 * NEWS: Add information about this new feature.
2472 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2474 Avoid core dumps described in Savannah bug # 12124:
2476 * file.c: New variable snapped_deps remember whether we've run
2477 snap_deps().
2478 (snap_deps): Set it.
2479 * filedef.h: Extern it.
2480 * read.c (record_files): Check snapped_deps; if it's set then
2481 we're trying to eval a new target/prerequisite relationship from
2482 within a command script, which we don't support. Fatal.
2484 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2486 Implementation of the .DEFAULT_TARGET special variable.
2488 * read.c (eval): If necessary, update default_target_name when
2489 reading rules.
2490 * read.c (record_files): Update default_target_file if
2491 default_target_name has changed.
2492 * main.c (default_target_name): Define.
2493 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2494 default_target_name is set use default_target_file as a root
2495 target to make.
2496 * filedef.h (default_target_name): Declare.
2497 * dep.h (free_dep_chain):
2498 * misc.c (free_dep_chain): Change to operate on struct nameseq
2499 and change name to free_ns_chain.
2500 * file.c (snap_deps): Update to use free_ns_chain.
2502 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2504 Implementation of the second expansion in explicit rules,
2505 static pattern rules and implicit rules.
2507 * read.c (eval): Refrain from chopping up rule's dependencies.
2508 Store them in a struct dep as a single dependency line. Remove
2509 the code that implements SySV-style automatic variables.
2511 * read.c (record_files): Adjust the code that handles static
2512 pattern rules to expand all percents instead of only the first
2513 one. Reverse the order in which dependencies are stored so that
2514 when the second expansion reverses them again they appear in
2515 the makefile order (with some exceptions, see comments in
2516 the code). Remove the code that implements SySV-style automatic
2517 variables.
2519 * file.c (snap_deps): Implement the second expansion and chopping
2520 of dependency lines for explicit rules.
2522 * implicit.c (struct idep): Define an auxiliary data type to hold
2523 implicit rule's dependencies after stem substitution and
2524 expansion.
2526 * implicit.c (free_idep_chain): Implement.
2528 * implicit.c (get_next_word): Implement helper function for
2529 parsing implicit rule's dependency lines into words taking
2530 into account variable expansion requests. Used in the stem
2531 splitting code.
2533 * implicit.c (pattern_search): Implement the second expansion
2534 for implicit rules. Also fixes bug #12091.
2536 * commands.h (set_file_variables): Declare.
2537 * commands.c (set_file_variables): Remove static specifier.
2539 * dep.h (free_dep_chain): Declare.
2540 * misc.c (free_dep_chain): Implement.
2542 * variable.h (variable_expand_for_file): Declare.
2543 * expand.c (variable_expand_for_file): Remove static specifier.
2545 * make.h (strip_whitespace): Declare.
2546 * function.c (strip_whitespace): Remove static specifier.
2548 2005-02-26 Paul D. Smith <psmith@gnu.org>
2550 * main.c (main): Check for ferror() when reading makefiles from stdin.
2551 Apparently some shells in Windows don't close pipes properly and
2552 require this check.
2554 2005-02-24 Jonathan Grant <jg@jguk.org>
2556 * configure.in: Add MinGW configuration options, and extra w32 code
2557 directory.
2558 * Makefile.am: Add MinGW configuration options, and extra w32 code
2559 directory.
2560 * main.c: Determine correct program string (after last \ without .exe).
2561 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2562 type fix x2
2563 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2564 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2565 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2566 environment support.
2568 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2570 * function.c (func_shell): When initializing error_prefix, check
2571 that reading file name is not null. This fixes long-standing
2572 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2574 2005-02-09 Paul D. Smith <psmith@gnu.org>
2576 * maintMakefile: Update the CVS download URL to simplify them.
2577 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2578 downloading the .texi files from Savannah now.
2580 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2582 * main.c (handle_non_switch_argument): Only add variables to
2583 command_variables if they're not already there: duplicate settings
2584 waste space and can be confusing to read.
2586 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2587 this header is never included by non-WINDOWS32 code, and it
2588 requires <config.h> to define which isn't always included first.
2590 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2591 testing MINGW32 versions.
2593 * main.c (log_working_directory): flush stdout to be sure the WD
2594 change is printed before any stderr messages show up.
2596 2005-02-01 Paul D. Smith <psmith@gnu.org>
2598 * maintMakefile (po_repo): Update the GNU translation site URL.
2600 2004-12-01 Paul D. Smith <psmith@gnu.org>
2602 * main.c (main): Change char* env_shell to struct variable shell_var.
2603 * variable.c (target_environment): Use new shell_var.
2605 2004-11-30 Paul D. Smith <psmith@gnu.org>
2607 * configure.in: The old way we avoided creating build.sh from
2608 build.sh.in before build.sh.in exists doesn't work anymore; we
2609 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2610 the help!). This also keeps automake from complaining.
2611 * Makefile.am (README): Add a dummy target so automake won't
2612 complain that this file doesn't exist when we checkout from CVS.
2613 * maintMakefile (.dep_segment): Rewrite this rule since newer
2614 versions of automake don't provide DEP_FILES.
2616 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2618 Implementation of `realpath' and `abspath' built-in functions.
2620 * configure.in: Check for realpath.
2621 * function.c (abspath): Return an absolute file name that does
2622 not contain any `.' or `..' components, nor repeated `/'.
2623 * function.c (func_abspath): For each name call abspath.
2624 * function.c (func_realpath): For each name call realpath
2625 from libc or delegate to abspath if realpath is not available.
2626 * doc/make.texi (Functions for File Names): Document new functions.
2627 * doc/make.texi (Quick Reference): Ditto.
2629 2004-11-28 Paul D. Smith <psmith@gnu.org>
2631 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2632 arguments. Fixes bug #10252.
2634 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2636 * main.c (main): Set SHELL to v_noexport by default. Remember the
2637 original environment setting of SHELL in the env_shell variable.
2638 * main.h: Export new env_shell variable.
2639 * variable.c (target_environment): If we find a v_noexport
2640 variable for SHELL, add a SHELL variable with the env_shell value.
2641 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2642 * doc/make.texi (Variables/Recursion): Ditto.
2644 2004-11-28 Paul D. Smith <psmith@gnu.org>
2646 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2647 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2648 Patch by Alessandro Vesely.
2650 2004-11-12 Paul D. Smith <psmith@gnu.org>
2652 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2653 the command line if it's inside a string.
2654 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2656 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2658 * function.c (func_lastword): New function: return last word
2659 from the list of words.
2660 * doc/make.texi: Document $(lastword ). Fix broken links in
2661 Quick Reference section.
2663 2004-10-06 Paul D. Smith <psmith@gnu.org>
2665 Apply patch from Alessandro Vesely, provided with bug # 9748.
2666 Fix use of tmpnam() to work with Borland C.
2668 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2669 construction of a temporary filename, and call new function
2670 create_batch_filename().
2671 (create_batch_filename) [WINDOWS32]: New function to create a
2672 temporary filename.
2674 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2676 * read.c (record_target_var): Expand simple pattern-specific
2677 variable.
2678 * variable.c (initialize_file_variables): Do not expand simple
2679 pattern-specific variable.
2681 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2683 * remake.c (update_file_1): When rebuilding makefiles inherit
2684 dontcare flag from a target that triggered update.
2686 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2688 * variable.c (initialize_file_variables): Mark pattern-specific
2689 variable as a per-target and copy export status.
2691 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2693 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2695 * implicit.c (pattern_search): When considering an implicit rule's
2696 prerequisite check that it is actually a target rather then
2697 just an entry in the file hashtable.
2699 2004-09-21 Paul D. Smith <psmith@gnu.org>
2701 * read.c (readstring): Fix some logic errors in backslash handling.
2702 (eval): Remove some unnecessary processing in buffer handling.
2703 (record_target_var): Assert that parse_variable_definition() succeeded.
2704 Reported by: Markus Mauhart <qwe123@chello.at>.
2706 * misc.c: Removed the sindex() function. All instances of this
2707 function were trivially replaceable by the standard strstr()
2708 function, and that function will always have better (or certainly
2709 no worse) performance than the very simple-minded algorithm
2710 sindex() used. This can matter with complex makefiles.
2711 * make.h: Remove the prototype for sindex().
2712 * function.c (subst_expand): Convert sindex() call to strstr().
2713 This means we no longer need to track the TLEN value so remove that.
2714 (func_findstring): Convert sindex() to strstr().
2715 * commands.c (chop_commands): Convert sindex() calls to strstr().
2716 Suggested by: Markus Mauhart <qwe123@chello.at>.
2718 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2719 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2720 If SHELL is set to CMD.EXE then assume it's batch-mode and
2721 non-unixy. I wrote the code differently from the patch, though,
2722 to make it safer. This also resolves bug #9174.
2724 2004-09-20 Paul D. Smith <psmith@gnu.org>
2726 * expand.c (variable_expand_string): Modify to invoke
2727 patsubst_expand() instead of subst_expand(); the latter didn't
2728 handle suffix patterns correctly.
2729 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2730 was used only from variable_expand_string() and is no longer used
2731 there.
2732 (func_subst): Ditto, on call to subst_expand().
2733 (patsubst_expand): Require the percent pointers to point to the
2734 character after the %, not to the % itself.
2735 * read.c (record_files): New call criteria for patsubst_expand().
2736 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2737 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2739 2004-09-19 Paul D. Smith <psmith@gnu.org>
2741 * function.c (subst_expand): Fix a check in by_word: look for a
2742 previous blank if we're beyond the beginning of the string, not
2743 the beginning of the word.
2744 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2746 2004-05-16 Paul D. Smith <psmith@gnu.org>
2748 * remake.c (update_goal_chain): Change the argument specifying
2749 whether we're rebuilding makefiles to be a global variable,
2750 REBUILDING_MAKEFILES.
2751 (complain): Extract the code that complains about no rules to make
2752 a target into a separate function.
2753 (update_file_1): If we tried to rebuild a file during the makefile
2754 rebuild phase and it was dontcare, then no message was printed.
2755 If we then try to build the same file during the normal build,
2756 print a message this time.
2757 (remake_file): Don't complain about un-remake-able files when
2758 we're rebuilding makefiles.
2760 2004-05-11 Paul D. Smith <psmith@gnu.org>
2762 * job.c (construct_command_argv_internal): OS/2 patches from
2763 Andreas Buening <andreas.buening@nexgo.de>.
2765 2004-05-10 Paul D. Smith <psmith@gnu.org>
2767 * remake.c (update_file): Don't walk the double-colon chain unless
2768 this is a double-colon rule. Fix suggested by Boris Kolpackov
2769 <boris@kolpackov.net>.
2771 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2772 * readme.vms: New section describing OpenVMS support and issues.
2773 * default.c (default_variables): Add support for IA64.
2774 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2775 without some privilege aborts make with the error
2776 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2777 pressing Ctrl+Y and the input device is no terminal. The change
2778 catches this error and just continues.
2780 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2782 2004-04-25 Paul D. Smith <psmith@gnu.org>
2784 * commands.c (set_file_variables): Set $< properly in the face of
2785 order-only prerequisites.
2786 Patch from Boris Kolpackov <boris@kolpackov.net>
2788 2004-04-21 Bob Byrnes <byrnes@curl.com>
2790 * main.c (main): Notice failures to remake makefiles.
2792 2004-03-28 Paul D. Smith <psmith@gnu.org>
2794 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2796 * job.c: No default shell for RISC OS.
2797 (load_too_high): Hard-code the return to 1.
2798 (construct_command_argv_internal): No sh_chars or sh_cmds.
2799 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2801 2004-03-20 Paul D. Smith <psmith@gnu.org>
2803 * variable.c (do_variable_definition): Don't append from the
2804 global set if a previous non-appending target-specific variable
2805 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2806 (with fix).
2808 * expand.c (reference_variable): Don't give up on variables with
2809 no value that have the target-specific append flag set: they might
2810 have a value after all. Reported by Oliver Schmidt
2811 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2812 <nikulin@dx1cmd.inp.nsk.su>.
2814 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2815 refer to absolute pathnames in directories that don't exist: some
2816 portion of the makefile could create those directories before we
2817 match the pattern. Fixes bugs #775 and #108.
2819 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2821 * main.c (main): Free makefile_mtimes if we have any.
2822 * README.W32.template: Update documentation for the current status
2823 of the MS-Windows port.
2824 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2825 environment variable is sometimes already defined which causes the
2826 build to fail.
2827 * main.c (debug_signal_handler): Only define this function if
2828 SIGUSR1 is available.
2830 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2832 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2833 * README.OS2.template: Documentation updates.
2834 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2835 link line for safety.
2836 * maintMakefile (build.sh.in): Remove an extraneous ")".
2837 * job.c (child_execute_job): Close saved FDs.
2838 * job.c (exec_command) [OS/2]: exec_command(): If the command
2839 can't be exec'ed and if the shell is not Unix-sh, then try again
2840 with argv = { "cmd", "/c", ... }. Normally, this code is never
2841 reached for the cmd shell unless the command really doesn't exist.
2842 (construct_command_argv_internal) [OS/2]: The code for cmd
2843 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2844 The CMD builtin commands are case insensitive so use strcasecmp().
2846 2004-03-19 Paul D. Smith <psmith@gnu.org>
2848 * read.c (do_define): Re-order line counter increment so the count
2849 is accurate (we were losing one line per define). Reported by
2850 Dave Yost <Dave@Yost.com>.
2852 2004-03-06 Paul D. Smith <psmith@gnu.org>
2854 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2855 compiler.
2856 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2857 * misc.c (message,error,fatal): Ditto.
2858 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2859 * config.h.W32.template: Ditto.
2860 * config.h-vms.template: Ditto.
2861 * config.ami.template: Ditto.
2863 2004-03-04 Paul D. Smith <psmith@gnu.org>
2865 * README.template: Add a note about broken /bin/sh on SunOS
2866 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2868 * misc.c (message, error, fatal): Don't use "..." if we're using
2869 varargs. ansi2knr should handle this but it doesn't work: it
2870 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2871 done. On many systems (SunOS for example) va_dcl is a #define.
2872 So, force the use of the non-"..." version on pre-ANSI compilers.
2874 * maintMakefile (sign-dist): Create some rules to help automate
2875 the new GNU ftp upload method.
2877 2004-02-24 Paul D. Smith <psmith@gnu.org>
2879 * config.h.W32.template: Add HAVE_STDARG_H
2880 * config.h-vms.template: Ditto.
2881 * config.ami.template: Ditto.
2883 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2885 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2886 * build_w32.bat: Remove extra "+".
2888 2004-02-23 Paul D. Smith <psmith@gnu.org>
2890 * make.h: Create an UNUSED macro to mark unused parameters.
2891 * (many): Clean up warnings by applying UNUSED, fixing
2892 signed/unsigned incompatibilities, etc.
2894 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2895 autoconf warnings.
2896 * filedef.h: Name the command_state enumeration.
2897 * file.c (set_command_state): Use the enumeration in the function
2898 argument.
2900 * configure.in: Explicitly set SET_MAKE to empty, to disable
2901 MAKE=make even when no make already exists. Fix bug #3823.
2903 2004-02-22 Paul D. Smith <psmith@gnu.org>
2905 * maintMakefile: Perl script to clean up all non-CVS files. Use
2906 it on all the subdirectories for the cvs-clean target.
2908 * main.c (decode_switches): Require non-empty strings for all our
2909 string command-line options. Fixes Debian bug # 164165.
2911 * configure.in: Check for stdarg.h and varargs.h.
2912 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2913 for printing messages.
2914 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2915 (message): Ditto.
2916 (error): Ditto.
2917 (fatal): Ditto.
2919 A number of patches for OS/2 support from Andreas Buening
2920 <andreas.buening@nexgo.de>:
2922 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2923 disable the SIGCHLD handler.
2924 (reap_children) [OS/2]: Remove special handling of job_rfd.
2925 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2926 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2927 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2928 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2929 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2930 systems.
2932 2004-02-21 Paul D. Smith <psmith@gnu.org>
2934 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2935 <mail@kristov.de> reports that if process_begin() fails we don't
2936 handle the error condition correctly in all cases.
2937 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2938 to have a newline on the message.
2940 * job.c (construct_command_argv_internal): Add "test" to UNIX
2941 sh_cmds[]. Fixes Savannah bug # 7606.
2943 2004-02-04 Paul D. Smith <psmith@gnu.org>
2945 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2946 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2947 Hartmut Becker <Hartmut.Becker@hp.com>.
2949 2004-01-21 Paul D. Smith <psmith@gnu.org>
2951 * job.c (load_too_high): Implement an algorithm to control the
2952 "thundering herd" problem when using -l to control job creation
2953 via the load average. The system only recomputes the load once a
2954 second but we can start many jobs in a second. To solve this we
2955 keep track of the number of jobs started in the last second and
2956 apply a weight to try to guess what a correct load would be.
2957 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2958 Also fixes bug #4693.
2959 (reap_children): Decrease the job count for this second.
2960 (start_job_command): Increase the job count for this second.
2962 * read.c (conditional_line): Expand the text after ifn?def before
2963 checking to see if it's a single word. Fixes bug #7257.
2965 2004-01-09 Paul D. Smith <psmith@gnu.org>
2967 * file.c (print_file): Recurse to print all targets in
2968 double-colon rules. Fixes bug #4518, reported (with patch) by
2969 Andrew Chatham <chatham@google.com>.
2971 2004-01-07 Paul D. Smith <psmith@gnu.org>
2973 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2974 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2975 AC_FUNC_SETVBUF_REVERSED.
2977 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2978 (MAKE Variable): Fix Savannah bug #4898.
2980 * job.c (construct_command_argv_internal): Add "!" to the list of
2981 shell escape chars. POSIX sh allows it to appear before a
2982 command, to negate the exit code. Fixes bug #6404.
2984 * implicit.c (pattern_search): When matching an implicit rule,
2985 remember which dependencies have the ignore_mtime flag set.
2986 Original fix provided in Savannah patch #2349, by Benoit
2987 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2989 2003-11-22 Paul D. Smith <psmith@gnu.org>
2991 * README.W32.template (Outputs): Clarification on -j with
2992 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2993 <jg-make@jguk.org>.
2995 2003-11-02 Paul D. Smith <psmith@gnu.org>
2997 * function.c (func_if): Strip all the trailing whitespace from the
2998 condition, then don't expand it. Fixed bug # 5798.
3000 * expand.c (recursively_expand_for_file): If we're expanding a
3001 variable with no file context, then use the variable's context.
3002 Fixes bug # 6195.
3004 2003-10-21 Paul D. Smith <psmith@gnu.org>
3006 * main.c (log_working_directory): Add newlines to printf()s.
3008 * README.cvs: Add a note to ignore warnings during autoreconf.
3010 * maintMakefile (po_repo): Set a new URL for PO file updates.
3011 (get-config/config.guess get-config/config.sub): Get these files
3012 from the Savannah config project instead of ftp.gnu.org.
3014 2003-10-05 Paul Eggert <eggert@twinsun.com>
3016 * main.c (main): Avoid potential subscript error if environ has
3017 short strings.
3019 2003-08-22 Paul D. Smith <psmith@gnu.org>
3021 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3022 systems which don't yet implement the C89 standard :-/.
3024 2003-07-18 Paul D. Smith <psmith@gnu.org>
3026 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3027 [WINDOWS32]: Initialize hash.
3029 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3031 * dir.c (read_dirstream): Provide a workaround for broken versions of
3032 the MinGW dirent structure.
3034 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3036 * w32/include/dirent.h: Add __MINGW32__ filter.
3038 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3040 * make.h: Add global declaration of *make_host.
3041 * main.c (print_usage): Remove local declaration of *make_host.
3042 (print_version): Display "This program built for ..." after Copyright
3043 notice.
3045 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3047 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3048 execution of "makeinfo --html make.texi".
3050 2003-04-30 Paul D. Smith <psmith@gnu.org>
3052 * build.template: Make some changes to maybe allow this script to
3053 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3055 * README.OS2.template: New file for OS/2 support. Original
3056 contributed by Andreas Buening.
3057 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3058 DOS-style paths.
3060 2003-04-19 Paul D. Smith <psmith@gnu.org>
3062 Fix bug #1405: allow a target to match multiple pattern-specific
3063 variables.
3065 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3066 variable.c, where they've always belonged.
3067 * rule.h: Move the prototypes and struct pattern_var as well.
3068 * variable.c (initialize_file_variables): Invoke
3069 lookup_pattern_var() in a loop, until no more matches are found.
3070 If a match is found, create a new variable set for the target's
3071 pattern variables. Then merge the contents of each matching
3072 pattern variable set into the target's pattern variable set.
3073 (lookup_pattern_var): Change this function to be usable
3074 in a loop. It takes a starting position: if NULL, start at the
3075 beginning; if non-NULL, start with the pattern variable after that
3076 position, and return the next matching pattern.
3077 (create_pattern_var): Create a unique instance of
3078 pattern-specific variables for every definition in the makefile.
3079 Don't combine the same pattern together. This allows us to
3080 process the variable handling properly even when the same pattern
3081 is used multiple times.
3082 (parse_variable_definition): New function: break out the parsing
3083 of a variable definition line from try_variable_definition.
3084 (try_variable_definition): Call parse_variable_definition to
3085 parse.
3086 (print_variable_data_base): Print out pattern-specific variables.
3087 * variable.h (struct variable): Remember when a variable is
3088 conditional. Also remember its flavor.
3089 (struct pattern_var): Instead of keeping a variable set, we just
3090 keep a single variable for each pattern.
3091 * read.c (record_target_var): Each pattern variable contains only a
3092 single variable, not a set, so create it properly.
3093 * doc/make.texi (Pattern-specific): Document the new behavior.
3095 2003-04-17 Paul D. Smith <psmith@gnu.org>
3097 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3098 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3099 file/directory naming rules for VMS so I can't tell whether this
3100 is correct or not.
3102 2003-04-09 Paul D. Smith <psmith@gnu.org>
3104 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3105 DOS-style pathnames: backslash separators and drive specifiers.
3107 2003-03-28 Paul D. Smith <psmith@gnu.org>
3109 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3110 the intermediate flag on all targets. Fixes bug #2515.
3112 2003-03-24 Paul D. Smith <psmith@gnu.org>
3114 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3115 Upgrade to autoconf 2.57 and automake 1.7.3.
3117 * job.c: More OS/2 changes from Andreas Buening.
3119 * file.c (print_file): Fix variable initialization.
3120 Fixes bug #2892.
3122 * remake.c (notice_finished_file):
3124 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3125 some calls (like readdir()) return NULL in valid situations
3126 without resetting errno. Fixes bug #2846.
3128 2003-02-25 Paul D. Smith <psmith@gnu.org>
3130 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3132 * job.c (_is_unixy_shell) [OS/2]: New function.
3133 Set default shell to /bin/sh.
3134 (reap_children): Close the job_rfd pipe here since we don't use a
3135 SIGCHLD handler.
3136 (set_child_handler_action_flags): define this to empty on OS/2.
3137 (start_job_command): Close the jobserver pipe and use
3138 child_execute_job() instead of fork/exec.
3139 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3140 rather than exec'ing, then reconfigure stdin/stdout.
3141 (exec_command): Rewrite to use spawn instead of exec. Return the
3142 PID of the child.
3144 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3145 in DOS. Handle the TEMP environment variable as in DOS. Don't
3146 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3147 use -j in DOS mode. Use child_execute_job() instead of
3148 exec_command().
3150 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3151 spawn() instead.
3153 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3154 prototypes that return values.
3156 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3158 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3159 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3160 for OS/2.
3161 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3162 DOS paths.
3164 2003-02-24 Paul D. Smith <psmith@gnu.org>
3166 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3167 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3168 (child_execute_job) [VMS]: Handle error status properly.
3169 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3171 * function.c (func_shell): Use EINTRLOOP() while reading from the
3172 subshell pipe (Fixes bug #2502).
3173 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3174 jobserver pipe.
3175 * main.c (main): Ditto.
3177 2003-01-30 Paul D. Smith <psmith@gnu.org>
3179 * read.c (eval): eval() was not fully reentrant, because the
3180 collapsed buffer was static. Change it to be an automatic
3181 variable so that eval() can be invoked recursively.
3182 Fixes bug # 2238.
3183 (eval): Apply patch # 1022: fix memory reference error on long
3184 target-specific variable lines.
3185 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3187 * function.c (check_numeric): Combine the is_numeric() function
3188 into this function, since it's only called from one place.
3189 Constify this function. Have it print the incorrect string in the
3190 error message. Fixes bug #2407.
3191 (strip_whitespace): Constify.
3192 (func_if): Constify.
3193 * expand.c (expand_argument): Constify.
3195 2003-01-29 Paul D. Smith <psmith@gnu.org>
3197 Fix bug # 2169, also reported by other people on various systems.
3199 * make.h: Some systems, such as Solaris and PTX, do not fully
3200 implement POSIX-compliant SA_RESTART functionality; important
3201 system calls like stat() and readdir() can still fail with EINTR
3202 even if SA_RESTART has been set on the signal handler. So,
3203 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3204 EINTR for system calls which return -1 or 0 (NULL), respectively,
3205 on error.
3206 Also, remove the old atomic_stat()/atomic_readdir() and
3207 HAVE_BROKEN_RESTART handling.
3209 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3211 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3212 * remake.c (touch_file): Ditto.
3214 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3215 * read.c (construct_include_path): Ditto.
3216 * remake.c (name_mtime): Ditto.
3217 * vpath.c (selective_vpath_search): Ditto.
3218 * dir.c (find_directory): Ditto.
3219 (local_stat): Ditto.
3220 (find_directory): Use ENULLLOOP() to wrap opendir().
3221 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3223 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3224 atomic_readdir() handling.
3226 2003-01-22 Paul D. Smith <psmith@gnu.org>
3228 * function.c (func_call): Fix Bug #1744. If we're inside a
3229 recursive invocation of $(call ...), mask any of the outer
3230 invocation's arguments that aren't used by this one, so that this
3231 invocation doesn't "inherit" them accidentally.
3233 2002-12-05 Paul D. Smith <psmith@gnu.org>
3235 * function.c (subst_expand): Valery Khamenia reported a
3236 pathological performance hit when doing substitutions on very
3237 large values with lots of words: turns out we were invoking
3238 strlen() a ridiculous number of times. Instead of having each
3239 call to sindex() call strlen() again, keep track of how much of
3240 the text we've seen and pass the length to sindex().
3242 2002-11-19 Paul D. Smith <psmith@gnu.org>
3244 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3247 2002-11-16 Paul D. Smith <psmith@gnu.org>
3249 * NMakefile.template (OBJS): Add hash.c object file.
3250 * SMakefile.template (srcs): Ditto.
3251 * Makefile.ami (objs): Ditto.
3252 * build_w32.bat: Ditto.
3254 * Makefile.DOS.template: Remove extra dependencies.
3256 2002-10-25 Paul D. Smith <psmith@gnu.org>
3258 * expand.c (install_variable_buffer): New function. Install a new
3259 variable_buffer context and return the previous one.
3260 (restore_variable_buffer): New function. Free the current
3261 variable_buffer context and put a previously saved one back.
3262 * variable.h: Prototypes for {install,restore}_variable_buffer.
3263 * function.c (func_eval): Push a new variable_buffer context
3264 before we eval, then restore the old one when we're done.
3265 Fixes Bug #1517.
3267 * read.c (install_conditionals): New function. Install a new
3268 conditional context and return the previous one.
3269 (restore_conditionals): New function. Free the current
3270 conditional context and put a previously saved one back.
3271 (eval): Use the {install,restore}_conditionals for "include"
3272 handling.
3273 (eval_buffer): Use {install,restore}_conditionals to preserve the
3274 present conditional state before we evaluate the buffer.
3275 Fixes Bug #1516.
3277 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3278 and $(value ...).
3279 (Recursion): Add a variable index entry for CURDIR.
3281 * README.cvs: Update to appropriate versions.
3282 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3283 don't need to copy loadavg.c: automake is smart enough to create
3284 it for me. Still have a bug in automake related to ansi2knr tho.
3286 2002-10-14 Paul D. Smith <psmith@gnu.org>
3288 * remake.c (notice_finished_file): Only touch targets if they have
3289 at least one command (as per POSIX). Resolve Bug #1418.
3291 * *.c: Convert to using ANSI C-style function definitions.
3292 * Makefile.am: Enable the ansi2knr feature of automake.
3293 * configure.in: ditto.
3295 2002-10-13 Paul D. Smith <psmith@gnu.org>
3297 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3298 for automatic variable values like $^, etc. In the case of very
3299 large lists of prerequisites this causes problems. Instead reuse
3300 a static buffer (resizeable) for each variable.
3302 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3303 target-specific variable definitions. Check for it and set an
3304 "exported" flag.
3305 (record_target_var): Set the export field to v_export if the
3306 "exported" flag is set.
3307 * doc/make.texi (Target-specific): Document the ability to use
3308 "export".
3310 * doc/make.texi: Change the name of the section on automatic
3311 variables from "Automatic" to "Automatic Variables". Added text
3312 clarifying the scope of automatic variables.
3314 2002-10-04 Paul D. Smith <psmith@gnu.org>
3316 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3317 as () braces.
3318 (record_files): Ditto.
3320 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3321 the search for the '=' to only within the enclosing parens.
3323 2002-10-03 Paul D. Smith <psmith@gnu.org>
3325 Version 3.80 released.
3327 * dir.c: Change hash functions to use K&R function definition style.
3328 * function.c: Ditto.
3329 * read.c: Ditto.
3330 * variable.c: Ditto.
3332 Update to automake 1.7.
3334 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3335 (pdf): Remove this target as automake now provides one.
3337 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3339 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3341 * makefile.com: Updates for GNU make 3.80.
3342 * makefile.vms: Ditto.
3344 2002-09-23 Paul D. Smith <psmith@gnu.org>
3346 * read.c (enum make_word_type): Remove w_comment.
3347 (get_next_mword): Don't treat comment characters as special; where
3348 this function is used we will never see a comment (it's stripped
3349 before we get here) and treating comments specially means that
3350 targets like "foo\#bar" aren't handled properly.
3352 2002-09-18 Paul D. Smith <psmith@gnu.org>
3354 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3356 * read.c (eval): Expansion of arguments to export/unexport was
3357 ignoring all arguments after the first one. Change the algorithm
3358 to expand the whole line once, then parse the results.
3360 2002-09-17 Paul D. Smith <psmith@gnu.org>
3362 Fix Bug #940 (plus another bug I found while looking at this):
3364 * read.c (record_target_var): enter_file() will add a new entry if
3365 it's a double-colon target: we don't want to do that in this
3366 situation. Invoke lookup_file() and only enter_file() if it does
3367 not already exist. If the file we get back is a double-colon then
3368 add this variable to the "root" double-colon target.
3370 * variable.c (initialize_file_variables): If this file is a
3371 double-colon target but is not the "root" target, then initialize
3372 the root and make the root's variable list the parent of our
3373 variable list.
3375 2002-09-13 Paul D. Smith <psmith@gnu.org>
3377 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3379 * hash.c (round_up_2): Get rid of a warning.
3381 2002-09-12 Paul D. Smith <psmith@gnu.org>
3383 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3384 so it doesn't complain about getloadavg.c.
3386 * commands.c (set_file_variables): Make sure we always alloca() at
3387 least 1 character for the value of $? (for '\0').
3389 2002-09-11 Paul D. Smith <psmith@gnu.org>
3391 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3392 macro to use RESULT instead of the incorrect _RESULT_.
3394 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3395 and atomic_readdir(). We need to #include dirent.h to get this to
3396 work.
3397 * misc.c (atomic_readdir): Fix typos.
3399 2002-09-10 Paul D. Smith <psmith@gnu.org>
3401 * read.c (eval): Expand variable lists given to export and
3402 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3403 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3405 * doc/make.texi (Variables/Recursion): Document this.
3406 (Conditional Syntax): And here.
3408 2002-09-09 Paul D. Smith <psmith@gnu.org>
3410 * configure.in: Check for memmove().
3412 2002-09-07 Paul D. Smith <psmith@gnu.org>
3414 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3415 Michael Sterrett <msterret@coat.com> reports that while it has
3416 SA_RESTART, it does not work properly.
3418 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3419 that invokes stat() and loops to do it again if it returns EINTR.
3420 (atomic_readdir): Ditto, with readdir().
3422 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3423 and readdir() to atomic_stat() and atomic_readdir().
3425 2002-09-04 Paul D. Smith <psmith@gnu.org>
3427 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3428 reports that GNU make sometimes doesn't recognize that targets can
3429 be made, when directories can be created as prerequisites. He
3430 reports that changing the order of predicates in the DEP->changed
3431 flag test so that lookup_file() is always performed, solves this
3432 problem.
3434 2002-08-08 Paul D. Smith <psmith@gnu.org>
3436 * configure.in: Require a newer version of gettext.
3438 * misc.c (perror_with_name): Translate the format string (for
3439 right-to-left language support).
3440 (pfatal_with_name): Ditto.
3442 * main.c: Create a static array of strings to store the usage
3443 text. This is done to facilitate translations.
3444 (struct command_switch): Remove argdesc and description fields.
3445 (switches): Remove values for obsolete fields.
3446 (print_usage): Print each element of the usage array.
3448 * hash.c: Change function definitions to be K&R style.
3450 2002-08-02 Paul D. Smith <psmith@gnu.org>
3452 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3453 this one because it's too hard to get right. We'll look at it for
3454 a future release.
3455 * main.c (main): Don't create the .TARGETS variable.
3456 * variable.c (handle_special_var): Don't handle .TARGETS.
3458 2002-08-01 Paul D. Smith <psmith@gnu.org>
3460 * main.c (switches): Add a new option, -B (--always-make). If
3461 specified, make will rebuild all targets that it encounters even
3462 if they don't appear to be out of date.
3463 (always_make_flag): New flag.
3464 * make.h: Extern always_make_flag.
3465 * remake.c (update_file_1): Check always_make_flag; if it's set we
3466 will always rebuild any target we can, even if none of its
3467 prerequisites are newer.
3468 * NEWS: Mention it.
3470 * doc/make.texi (Shell Function): Make it clear that make
3471 variables marked as "export" are not passed to instances of the
3472 shell function.
3474 Add new introspection variable .VARIABLES and .TARGETS.
3476 * variable.c (handle_special_var): New function. If the variable
3477 reference passed in is "special" (.VARIABLES or .TARGETS),
3478 calculate the new value if necessary. .VARIABLES is handled here:
3479 walk through the hash of defined variables and construct a value
3480 which is a list of the names. .TARGETS is handled by
3481 build_target_list().
3482 (lookup_variable): Invoke handle_special_var().
3483 * file.c (build_target_list): Walk through the hask of known files
3484 and construct a list of the names of all the ones marked as
3485 targets.
3486 * main.c (main): Initialize them to empty (and as simple variables).
3487 * doc/make.texi (Special Variables): Document them.
3488 * NEWS: Mention them.
3490 * variable.h (struct variable): Add a new flag "exportable" which
3491 is true if the variable name is valid for export.
3492 * variable.c (define_variable_in_set): Set "exportable" when a new
3493 variable is defined.
3494 (target_environment): Use the "exportable" flag instead of
3495 re-checking the name here... an efficiency improvement.
3497 2002-07-31 Paul D. Smith <psmith@gnu.org>
3499 * config.h-vms.template: Updates to build on VMS. Thanks to
3500 Brian_Benning@aksteel.com for helping verify the build.
3501 * makefile.com: Build the new hash.c file.
3502 * hash.h: Use strcpmi(), not stricmp(), in the
3503 HAVE_CASE_INSENSITIVE_FS case.
3505 2002-07-30 Paul D. Smith <psmith@gnu.org>
3507 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3508 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3509 Reported by <Brian_Benning@aksteel.com>.
3511 2002-07-10 Paul D. Smith <psmith@gnu.org>
3513 * variable.c (pop_variable_scope): Remove variable made unused by
3514 new hash infrastructure.
3515 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3516 comparisons as well as name comparisons.
3517 * variable.h: Add a prototype for new hash_init_function_table().
3518 * file.c (lookup_file): Remove variables made unused by new hash
3519 infrastructure.
3520 * dir.c (directory_contents_hash_2): Missing return of hash value.
3521 (dir_contents_file_exists_p): Remove variables made unused by new
3522 hash infrastructure.
3525 Installed Greg McGary's integration of the hash functions from the
3526 GNU id-utils package:
3528 2002-07-10 Greg McGary <greg@mcgary.org>
3530 * scripts/functions/filter-out: Add literals to to the
3531 pattern space in order to add complexity, and trigger
3532 use of an internal hash table. Fix documentation strings.
3533 * scripts/targets/INTERMEDIATE: Reverse order of files
3534 passed to expected `rm' command.
3536 2002-07-10 Greg McGary <greg@mcgary.org>
3538 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3539 * hash.c: New file, taken from id-utils.
3540 * hash.h: New file, taken from id-utils.
3542 * make.h (HASH, HASHI): Remove macros.
3543 (find_char_unquote): Change arglist in decl.

3570 (find_directory): Use new hash table package.
3571 (dir_contents_file_exists_p): Likewise.

3591 (lookup_function): Remove `table' argument.
3592 Use new hash table package.
3593 (struct a_word) [chain, length]: New members.
3594 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3595 (struct a_pattern): New struct.
3596 (func_filter_filterout): Pass through patterns noting boundaries
3597 and '%', if present. Note a_word length. Use a hash table if
3598 arglists are large enough to justify cost.
3599 (function_table_init): Renamed from function_table.

3609 than a string constant, avoiding zillions of calls to strchr.
3610 Tighten inner search loops to test only for desired delimiters.
3612 * variable.c (variable_hash_1, variable_hash_2,
3613 variable_hash_cmp): New functions.

3628 2002-07-10 Paul D. Smith <psmith@gnu.org>
3630 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3631 prerequisite list. A real SysV make will expand the entire
3632 prerequisites list _twice_: we don't do that as it's a big
3633 backward-compatibility problem. We only replace those specific
3634 variables.
3636 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3637 references left in the list of prerequisites. Check for .POSIX as
3638 we record targets, so we can disable non-POSIX behavior while
3639 reading makefiles as well as running them.
3640 (eval): Check the prerequisite list to see if we have anything
3641 that looks like a SysV prerequisite variable reference.
3643 2002-07-09 Paul D. Smith <psmith@gnu.org>
3645 * doc/make.texi (Prerequisite Types): Add a new section describing
3646 order-only prerequisites.
3648 * read.c (uniquize_deps): If we have the same file as both a
3649 normal and order-only prereq, get rid of the order-only prereq,
3650 since the normal one supersedes it.
3652 2002-07-08 Paul D. Smith <psmith@gnu.org>
3654 * AUTHORS: Added Greg McGary to the AUTHORS file.
3655 * NEWS: Blurbed order-only prerequisites.
3656 * file.c (print_file): Show order-only deps properly when printing
3657 the database.
3659 * maintMakefile: Add "update" targets for wget'ing the latest
3660 versions of various external files. Taken from Makefile.maint in
3661 autoconf, etc.
3663 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3664 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3666 2002-07-07 Paul D. Smith <psmith@gnu.org>
3668 * po/*.po: Remove. We'll use wget to retrieve them at release
3669 time.
3671 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3672 rather than a shell you get an exception. Make sure we look up
3673 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3675 * remake.c (notice_finished_file): Fix handling of -t flag.
3676 Patch provided by Henning Makholm <henning@makholm.net>.
3678 * implicit.c (pattern_search): Some systems apparently run short
3679 of stack space, and using alloca() in this function caused an
3680 overrun. I modified it to use xmalloc() on the two variables
3681 which seemed like they might get large. Fixes Bug #476.
3683 * main.c (print_version): Update copyright notice to conform with
3684 GNU standards.
3685 (print_usage): Update help output.
3687 * function.c (func_eval): Create a new make function, $(eval
3688 ...). Expand the arguments, put them into a buffer, then invoke
3689 eval_buffer() on the resulting string.
3690 (func_quote): Create a new function, $(quote VARNAME). Inserts
3691 the value of the variable VARNAME without expanding it any
3692 further.
3694 * read.c (struct ebuffer): Change the linebuffer structure to an
3695 "eval buffer", which can be either a file or a buffer.
3696 (eval_makefile): Move the code in the old read_makefile() which
3697 located a makefile into here: create a struct ebuffer with that
3698 information. Have it invoke the new function eval() with that
3699 ebuffer.
3700 (eval_buffer): Create a new function that creates a struct ebuffer
3701 that holds a string buffer instead of a file. Have it invoke
3702 eval() with that ebuffer.
3703 (eval): New function that contains the guts of the old
3704 read_makefile() function: this function parses makefiles. Obtains
3705 data to parse from the provided ebuffer. Some modifications to
3706 make the flow of the function cleaner and clearer. Still could
3707 use some work here...
3708 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3709 contents of the define/endef variable from the ebuffer.
3710 (readstring): Read the next line from a string-style ebuffer.
3711 (readline): Read the next line from an ebuffer. If it's a string
3712 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3713 from the file.
3715 * dep.h (eval_buffer): Prototype eval_buffer();
3717 * variable.c (do_variable_definition): Make sure that all
3718 non-target-specific variables are registered in the global set.
3719 If we're invoked from an $(eval ...) we might be inside a $(call
3720 ...) or other function which has pushed a variable scope; we still
3721 want to define our variables from evaluated makefile code in the
3722 global scope.
3724 2002-07-03 Greg McGary <greg@mcgary.org>
3726 * dep.h (struct dep) [ignore_mtime]: New member.
3727 [changed]: convert to a bitfield.
3728 * implicit.c (pattern_search): Zero ignore_mtime.
3729 * main.c (main, handle_non_switch_argument): Likewise.
3730 * rule.c (convert_suffix_rule): Likewise.
3731 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3732 (read_makefile): Parse '|' in prerequisite list.
3733 (uniquize_deps): Consider ignore_mtime when comparing deps.
3734 * remake.c (update_file_1, check_dep): Don't force remake for
3735 dependencies that have d->ignore_mtime.
3736 * commands.c (FILE_LIST_SEPARATOR): New constant.
3737 (set_file_variables): Don't include a
3738 prerequisite in $+, $^ or $? if d->ignore_mtime.
3739 Define $|.
3741 2002-06-18 Paul D. Smith <psmith@gnu.org>
3743 * make.texinfo: Updates for next revision. New date/rev/etc.
3744 Recreate all Info menus. Change license on the manual to the GNU
3745 Free Documentation License. A number of typos.
3746 (Variables Simplify): Don't use "-" before it's defined.
3747 (Automatic Prerequisites): Rewrite the target example to work
3748 properly if the compile fails. Remove incorrect comments about
3749 how "set -e" behaves.
3750 (Text Functions): Move the "word", "wordlist", "words", and
3751 "firstword" functions here, from "File Name Functions".
3752 * make-stds.texi: Update from latest GNU version.
3753 * fdl.texi: (created) Import the latest GNU version.
3755 2002-06-06 Paul D. Smith <psmith@gnu.org>
3757 * variable.c (do_variable_definition): New function: extract the
3758 part of try_variable_definition() that actually sets the value
3759 into a separate function.
3760 (try_variable_definition): Call do_variable_definition() after
3761 parsing the variable definition string.
3762 (define_variable_in_set): Make the name argument const.
3764 * variable.h (enum variable_flavor): Make public.
3765 (do_variable_definition): Create prototype.
3767 * read.c (read_all_makefiles): Create a new built-in variable,
3768 MAKEFILE_LIST.
3769 (read_makefile): Add each makefile read in to this variable value.
3771 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3773 * Makefile.DOS.template: Tweak according to changes in the
3774 distribution. Add back the dependencies of *.o files.
3776 * configh.dos.template: Synchronize with config.h.in.
3778 2002-05-09 Paul D. Smith <psmith@gnu.org>
3780 * file.c (file_timestamp_now): Use K&R function declaration.
3782 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3783 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3784 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3785 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3786 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3787 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3788 nlist.n_name is a pointer rather than an array.
3790 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3791 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3792 * configure.in: Use it instead of the old version.
3794 * main.c (main): Prefer setvbuf() to setlinebuf().
3796 2002-05-08 Paul D. Smith <psmith@gnu.org>
3798 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3799 (loadavg_LDADD): Ditto.
3801 2002-04-29 Paul D. Smith <psmith@gnu.org>
3803 * expand.c (recursively_expand_for_file): Rename
3804 recursively_expand() to recursively_expand_for_file() and provide
3805 an extra argument, struct file. If the argument is provided, set
3806 the variable scope to that of the file before expanding.
3807 * variable.h (recursively_expand): Make this a macro that invokes
3808 recursively_expand_for_file() with a NULL file pointer.
3809 * variable.c (target_environment): Call the renamed function and
3810 provide the current file context.
3811 Fixes Debian bug #144306.
3813 2002-04-28 Paul D. Smith <psmith@gnu.org>
3815 Allow $(call ...) user-defined variables to be self-referencing
3816 without throwing an error. Allows implementation of transitive
3817 closures, among other possibly useful things.
3818 Requested by: Philip Guenther <guenther@sendmail.com>
3820 * variable.h (struct variable): Add a new field: exp_count, and
3821 new macros to hold its size and maximum value.
3822 (warn_undefined): Make this a macro.
3823 * variable.c (define_variable_in_set): Initialize it.
3824 * expand.c (recursively_expand): If we detect recursive expansion
3825 of a variable, check the exp_count field. If it's greater than 0
3826 allow the recursion and decrement the count.
3827 (warn_undefined): Remove this (now a macro in variable.h).
3828 * function.c (func_call): Before we expand the user-defined
3829 function, modify its exp_count field to contain the maximum
3830 number of recursive calls we'll allow. After the call, reset it
3831 to 0.
3833 2002-04-21 Paul D. Smith <psmith@gnu.org>
3835 Modified to use latest autoconf (2.53), automake (1.6.1), and
3836 gettext (0.11.1). We're using gettext's new "external" support,
3837 to avoid including libintl source with GNU make.
3839 * README.cvs: New file. Explain how to build GNU make from CVS.
3841 * configure.in: Modify checking for the system glob library.
3842 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3843 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3844 etc. will manage it correctly). Set an automake conditional
3845 USE_LOCAL_GLOB to decide whether to compile the glob library.
3847 * getloadavg.c (main): Include make.h in the "TEST" program to
3848 avoid warnings.
3850 * Makefile.am: Remove special rules for loadavg. Replace them
3851 with Automake capabilities for building extra programs.
3853 * signame.c: This file does nothing if the system provide
3854 strsignal(). If not, it implements strsignal(). If the system
3855 doesn't define sys_siglist, then we make our own; otherwise we use
3856 the system version.
3857 * signame.h: Removed.
3859 * main.c (main): No need to invoke signame_init(). Update copyright.
3861 * ABOUT-NLS: Removed.
3862 * gettext.c: Removed.
3863 * gettext.h: Get a simplified copy from the gettext package.
3864 * po/*: Created.
3865 * i18n/*.po: Moved to po/.
3866 * i18n/: Removed.
3868 * config/*: Created. Contains package configuration helper files.
3869 * config.guess, config.sub: Moved to config directory.
3871 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3872 Rework to use new-style autoconf features. Use the "external"
3873 mode for gettext. Make the build.sh config file conditional on
3874 whether build.sh.in exists, to avoid autoconf errors.
3875 * acinclude.m4: Removed almost all macros as being obsolete.
3876 Rewrote remaining macros to use AC_DEFINE.
3877 * acconfig.h: Removed.
3879 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3880 conditional to handle customs support. Remove special handling
3881 for i18n features.
3883 2002-04-20 Paul D. Smith <psmith@gnu.org>
3885 * function.c (func_call): Don't mark the argument variables $1,
3886 etc. as recursive. They've already been fully expanded so
3887 there's no need to do it again, and doing so strips escaped $'s.
3888 Reported by Sebastian Glita <glseba@yahoo.com>.
3890 * remake.c (notice_finished_file): Walk through double-colon
3891 entries via the prev field, not the next field!
3892 Reported by Greg McGary <greg@mcgary.org>.
3894 * main.c (main): If the user specifies -q and asks for a specific
3895 target which is a makefile, we got an assert. In that case it
3896 turns out we should continue normally instead.
3898 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3900 * i18n/he.po: Installed a new translation.
3902 2002-01-07 Paul D. Smith <psmith@gnu.org>
3904 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3906 2001-12-04 Paul D. Smith <psmith@gnu.org>
3908 * i18n/ja.po: Installed an updated translation.
3910 2001-09-06 Paul Eggert <eggert@twinsun.com>
3912 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3913 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3915 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3916 are available.
3917 (main): Get rid of any avoidable limit on stack size.
3919 2001-09-04 Paul D. Smith <psmith@gnu.org>
3921 * i18n/da.po: Installed an updated translation.
3923 2001-08-03 Paul D. Smith <psmith@gnu.org>
3925 * i18n/fr.po: Installed an updated translation.
3926 Resolves Debian bug #106720.
3928 2001-06-13 Paul D. Smith <psmith@gnu.org>
3930 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3931 translation.
3933 2001-06-11 Paul D. Smith <psmith@gnu.org>
3935 * i18n/ko.po: Installed a new translation.
3937 2001-05-06 Paul D. Smith <psmith@gnu.org>
3939 Modify the EINTR handling.
3941 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3942 the way in which we manage the file descriptor/signal handler race
3943 trap to be more efficient.
3945 2001-05-06 Paul Eggert <eggert@twinsun.com>
3947 Restart almost all system calls that are interrupted, instead
3948 of worrying about EINTR. The lone exception is the read() for
3949 job tokens.
3951 * configure.in (HAVE_SA_RESTART): New macro.
3952 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3953 * main.c (main): Use SA_RESTART instead of the old,
3954 nonstandard SA_INTERRUPT.
3956 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3957 * main.c (bsd_signal): New function or macro,
3958 if the implementation doesn't supply it.
3959 (The bsd_signal function will be in POSIX 1003.1-200x.)
3960 (HANDLESIG): Remove.
3961 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3963 * make.h (EINTR_SET): Remove.
3964 (SA_RESTART): New macro.
3966 * arscan.c (ar_member_touch): Don't worry about EINTR.
3967 * function.c (func_shell): Likewise.
3968 * job.c (reap_children, free_child, new_job): Likewise.
3969 * main.c (main): Likewise.
3970 * remake.c (touch_file, name_mtime): Likewise.
3972 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3973 if fstat failed with errno!=EINTR, the error was ignored.
3975 * job.c (set_child_handler_action_flags): New function.
3976 (new_job): Use it to temporarily clear the SIGCHLD action flags
3977 while reading the token.
3979 2001-05-02 Paul D. Smith <psmith@gnu.org>
3981 * job.c (start_job_command): Don't add define/endef per-line flags
3982 to the top-level flags setting.
3984 2001-04-03 Paul D. Smith <psmith@gnu.org>
3986 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3987 bit on error, so check for odd return values, not non-0 return
3988 values.
3989 (VMS_get_member_info): Calculate the timezone differences correctly.
3990 Reported by John Fowler <jfowler@nyx.net>.
3993 2001-03-14 Paul D. Smith <psmith@gnu.org>
3995 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3996 value before invoking define_variable().
3997 Reported by John Fowler <jfowler@nyx.net>.
3999 2001-02-07 Paul D. Smith <psmith@gnu.org>
4001 * read.c (record_target_var): If we reset the variable due to a
4002 command-line variable setting overriding it, turn off the "append"
4003 flag.
4005 2001-01-17 Paul D. Smith <psmith@gnu.org>
4007 * variable.c (lookup_variable) [VMS]: When getting values from the
4008 environment, allocate enough space for the _value_ plus escapes,
4009 not enough space for the name plus escapes :-/.
4010 Reported by John Fowler <jfowler@nyx.net>.
4012 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4013 warnings that make generates, so it doesn't look like an error.
4014 Reported by Karl Berry <karl@gnu.org>.
4017 Fix for PR/2020: Rework appended target-specific variables. I'm
4018 fairly confident this algorithm is finally correct.
4020 * expand.c (allocated_variable_append): Rewrite. Instead of
4021 expanding each appended variable then adding all the expanded
4022 strings together, we append all the unexpanded values going up
4023 through the variable set contexts, then expand the final result.
4024 This behaves just like non-target-specific appended variable
4025 values, while the old way didn't in various corner cases.
4026 (variable_append): New function: recursively append the unexpanded
4027 value of a variable, walking from the outermost variable scope to
4028 the innermost.
4029 * variable.c (lookup_variable): Remove the code that looked up the
4030 variable set list if the found variable was "append". We don't
4031 need this anymore.
4032 (lookup_variable_in_set): Make this non-static so we can use it
4033 elsewhere.
4034 (try_variable_definition): Use lookup_variable_in_set() rather
4035 than faking out current_variable_set_list by hand (cleanup).
4036 * variable.h: Add a prototype for the now non-static
4037 lookup_variable_in_set().
4039 2000-11-17 Paul D. Smith <psmith@gnu.org>
4041 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4042 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4043 before throwing a fit.
4045 2000-11-17 Paul D. Smith <psmith@gnu.org>
4047 * read.c (readline): CRLF calculations had a hole, if you hit the
4048 buffer grow scenario just right. Reworked the algorithm to avoid
4049 the need for len or lastlen at all. Problem description with
4050 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4052 2000-10-24 Paul D. Smith <psmith@gnu.org>
4054 * gettext.c (SWAP): Declare this with the prototype, otherwise
4055 some systems don't work (non-32-bit? Reported for Cray T3E).
4056 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4058 2000-10-05 Paul D. Smith <psmith@gnu.org>
4060 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4061 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4063 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4065 2000-09-22 Paul D. Smith <psmith@gnu.org>
4067 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4068 parts of the real gettext.h here, and we expect to really include
4069 the real gettext.h later. If we keep this #define, it's ignored.
4071 2000-09-21 Paul D. Smith <psmith@gnu.org>
4073 * main.c (log_working_directory): Rework the text to use complete
4074 sentences, to make life simpler for the translators.
4076 2000-08-29 Paul D. Smith <psmith@gnu.org>
4078 * file.c (remove_intermediates): Print a debug message before we
4079 remove intermediate files, so the user (if she uses -d) knows
4080 what's going on.
4082 2000-08-21 Paul D. Smith <psmith@gnu.org>
4084 * variable.c (try_variable_definition): Change how we handle
4085 target-specific append variable defns: instead of just setting the
4086 value, expand it as an append _but_ only within the current
4087 target's context. Otherwise we lose all but the last value if the
4088 variable is appended more than once within the current target
4089 context. Fixes PR/1831.
4091 2000-08-16 Paul D. Smith <psmith@gnu.org>
4093 * function.c (func_shell): Nul-terminate the buffer before
4094 printing an exec error message (just in case it's not!).
4095 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4097 2000-07-25 Paul D. Smith <psmith@gnu.org>
4099 * job.c (construct_command_argv_internal): Add "~" to the list of
4100 sh_chars[] which disallow optimizing out the shell call.
4102 2000-07-23 Paul Eggert <eggert@twinsun.com>
4104 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4105 supersedes --disable-nsec-timestamps.
4106 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4107 * README: Remove --disable-nsec-timestamps.
4109 * filedef.h (struct file.low_resolution_time): New member.
4110 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4111 * remake.c (update_file_1):
4112 Avoid spurious rebuilds due to low resolution time stamps,
4113 generalizing the earlier code that applied only to archive members.
4114 (f_mtime): Archive members always have low resolution time stamps.
4116 * configure.in: Remove --disable-nsec-timestamps, as this has
4117 been superseded by .LOW_RESOLUTION_TIME.
4119 2000-07-23 Paul Eggert <eggert@twinsun.com>
4121 * configure.in (enable_nsec_timestamps): Renamed from
4122 make_cv_nsec_timestamps, since enable/disable options
4123 shouldn't be cached.
4125 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4126 and Paul Eggert <eggert@twinsun.com>
4128 * file.c (file_timestamp_now):
4129 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4130 so that clock_gettime is not linked unless needed.
4132 * filedef.h (FILE_TIMESTAMP_HI_RES):
4133 Remove definition; "configure" now does this.
4135 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4136 to before high resolution file timestamp check,
4137 since that check now uses uintmax_t.
4138 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4139 high resolution file timestamps.
4140 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4141 so that we don't link in clock_gettime unnecessarily.
4143 2000-07-17 Paul D. Smith <psmith@gnu.org>
4145 * i18n/ja.po: New version of the translation file.
4147 2000-07-07 Paul D. Smith <psmith@gnu.org>
4149 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4150 the offset calculation.
4151 (name_mtime): Replace EINTR test with EINTR_SET macro.
4153 2000-07-07 Paul Eggert <eggert@twinsun.com>
4155 Fix for PR/1811:
4157 * remake.c (update_file_1):
4158 Avoid spurious rebuilds of archive members due to their
4159 timestamp resolution being only one second.
4160 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4161 the clock's resolution being lower than file timestamps'.
4162 When warning about future timestamps, report only the discrepancy,
4163 not the absolute value of the timestamp and the current time.
4165 * file.c (file_timestamp_now): New arg RESOLUTION.
4166 * filedef.h (file_timestamp_now): Likewise.
4167 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4169 2000-07-05 Paul D. Smith <psmith@gnu.org>
4171 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4172 to listp. Fixes PR/1793.
4174 2000-06-26 Paul Eggert <eggert@twinsun.com>
4176 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4178 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4180 * remake.c (f_mtime): Remove unused var memtime.
4182 2000-06-25 Martin Buchholz <martin@xemacs.org>
4184 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4185 Ran spell-check on make.texinfo.
4187 2000-06-23 Paul D. Smith <psmith@gnu.org>
4189 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4190 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4191 * make.h: Define these macros.
4193 * Version 3.79.1 released.
4195 * configure.in: Add a new option, --disable-nsec-timestamps, to
4196 avoid using sub-second timestamps on systems that support it. It
4197 can lead to problems, e.g. if your makefile relies on "cp -p".
4198 * README.template: Document the issue with "cp -p".
4200 * config.guess, config.sub: Updated.
