1 2011-11-13 Paul Smith <psmith@gnu.org>
3 * main.c (clean_jobserver): Don't write the free token to the pipe.
4 Change suggested by Tim Newsome <tnewsome@aristanetworks.com>

8 Patch provided by Troy Runkel <Troy.Runkel@mathworks.com>
10 2011-09-18 Paul Smith <psmith@gnu.org>
12 * main.c (main): If we're re-exec'ing and we're the master make,
13 then restore the job_slots value so it goes back into MAKEFLAGS
14 properly. See Savannah bug #33873.
16 * remake.c (library_search): STD_DIRS is computed when other
17 static vars like buflen etc. are computed, so it must be static
18 as well. See Savannah bug #32511.
20 2011-09-16 Paul Smith <psmith@gnu.org>
22 * maintMakefile (do-po-update): Apparently we have to avoid
23 certificate checks on the http://translationproject.org site now.
25 2011-09-12 Paul Smith <psmith@gnu.org>
27 * read.c (eval): Ensure exported variables are defined in the

30 2011-09-11 Paul Smith <psmith@gnu.org>
32 * Makefile.am (dist-hook): Remove w32/Makefile and .deps/ from the
33 dist file. Fixes Savannah bug #31489.

36 #!/usr/bin/make (for Savannah support request #106459)
38 2011-09-02 Paul Smith <psmith@gnu.org>
40 * remake.c (touch_file): If we have both -n and -t, -n takes
41 precedence. Patch from Michael Witten <mfwitten@gmail.com>
43 2011-08-29 Paul Smith <psmith@gnu.org>
45 * expand.c (variable_expand_string): Always allocate a new buffer
46 for a string we're expanding. The string we're working on can get
47 freed while we work on it (for example if it's the value of a
48 variable which modifies itself using an eval operation).
49 See Savannah patch #7534 for the original report by Lubomir Rintel.
51 2011-06-12 Paul Smith <psmith@gnu.org>
53 * read.c (parse_file_seq): Move the check for empty members out of
54 the loop so we can go to the next member properly.
55 Another fix for Savannah bug #30612.
57 * config.h-vms.template: Newer versions of VMS have strncasecmp()
58 Patch provided by: Hartmut Becker <becker.ismaning@freenet.de>
60 2011-05-07 Paul Smith <psmith@gnu.org>

64 private_var is set, then skip this variable and try the next one.
65 Fixes Savannah bug #32872.
67 * read.c (parse_file_seq): Ensure existence checks use glob().
69 2011-05-07 Eli Zaretskii <eliz@gnu.org>
71 * job.c (construct_command_argv_internal): Don't assume shellflags
72 is always non-NULL. Escape-protect characters special to the
73 shell when copying the value of SHELL into new_line. Fixes
74 Savannah bug #23922.
76 2011-05-02 Paul Smith <psmith@gnu.org>
78 * doc/make.texi (Special Variables): Add documentation for the new
79 words in .FEATURES. Fixes Savannah bug #32058.

81 Fixes Savannah bug #31582.
83 * function.c (func_sort): Use the same algorithm to count the
84 number of words we will get after the split, as we use to split.
85 Based on a patch from Matthias Hopf. Fixes Savannah bug #33125.
87 * make.h: Make global variable stack_limit extern.
88 Fixes Savannah bug #32753.
90 2011-05-01 Paul Smith <psmith@gnu.org>
92 * read.c (parse_file_seq): Don't try to invoke glob() unless there

107 * variable.c (shell_result): Send a string to the shell and store
108 the output.
109 (do_variable_definition): Handle f_shell variables: expand the
110 value, then send it to the shell and store the result.
111 (parse_variable_definition): Parse "!=" shell assignments.
112 * read.c (get_next_mword): Treat "!=" as a varassign word.
113 * function.c (fold_newlines): If trim_newlines is set remove all
114 trailing newlines; otherwise remove only the last newline.
115 (func_shell_base): Move the guts of the shell function here.
116 (func_shell): Call func_shell_base().
118 2011-02-21 Paul Smith <psmith@gnu.org>
120 * strcache.c (various): Increase performance based on comments
121 from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>. Stop looking for
122 a buffer when we find the first one that fits, not the best fit.
123 If there is not enough free space in a buffer move it to a
124 separate list so we don't have to walk it again.
125 * make.h (NDEBUG): Turn off asserts unless maintainer mode is set.
126 (strcache_add_len, strcache_setbufsize): Use unsigned length/size.
127 * maintMakefile (AM_CPPFLAGS): Enable MAKE_MAINTAINER_MODE.

526 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
528 * commands.c (set_file_variables): Avoid modifying the dep
529 chain to achieve uniqueness. Fixes savannah bug 25780.
531 * implicit.c (pattern_search): Instead of re-setting all automatic
532 variables for each rule we try, just update $*.
534 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
536 * variable.h (undefine_variable_in_set): New function declaration.
537 (undefine_variable_global): New macro.
539 * variable.c (undefine_variable_in_set): New function implementation.
541 * read.c (vmodifiers): Add undefine_v modifier.
542 (parse_var_assignment): Parse undefine.
543 (do_undefine): Handle the undefine directive.
544 (eval): Call do_undefine if undefine_v is set.
546 * main.c (.FEATURES): Add a keyword to indicate the new feature.
548 * doc/make.texi (Undefine Directive): Describe the new directive.
550 * NEWS: Add a note about the new directive.
552 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
554 * implicit.c (pattern_search): Initialize file variables only
555 if we need to parse a rule that requires the second expansion.
557 2009-10-03 Paul Smith <psmith@gnu.org>
559 * make.h: Include <alloca.h> even on systems where __GNUC__ is
560 defined. Not sure why it was done the other way.
561 Requested by David Boyce <dsb@boyski.com>.
563 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
565 * dep.h (dep): Add the DONTCARE bitfield.
567 * filedef.h (file):Add the NO_DIAG bitfield.
569 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
570 not struct file (a file can be a dependency of many targets,
571 some don't care, some do).
573 * remake.c (update_goal_chain): Propagate DONTCARE from struct
574 dep to struct file before updating the goal and restore it
575 afterwards.
576 (update_file): Don't prune the dependency graph if this target
577 has failed but the diagnostics hasn't been issued.
578 (complain): Scan the file's dependency graph to find the file
579 that caused the failure.
580 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
581 whether to print diagnostics.
583 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
585 2009-09-28 Paul Smith <psmith@gnu.org>
587 * doc/make.texi (Pattern Intro): Move the match algorithm
588 discussion into the "Pattern Match" node.
589 (Pattern Match): Expand on the pattern rule matching algorithm.
591 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
593 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
594 much of the command line on a single pass.
596 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
598 * varible.c (create_pattern_var): Insert variables into the
599 PATTERN_VARS list in the shortest patterns first order.
601 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
602 used to sort the rules.
603 (stemlen_compare): Compare two tryrule elements.
604 (pattern_search): Sort the rules so that they are in the shortest
605 stem first order.
607 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
609 * doc/make.texi (Pattern-specific Variable Values): Describe the
610 new pattern-specific variables application order.
611 (Introduction to Pattern Rules): Describe the new pattern rules
612 search order.
614 * NEWS: Add a note about the new behavior.
616 2009-09-27 Paul Smith <psmith@gnu.org>
618 * doc/make.texi (Double-Colon): Mention that pattern rules with
619 double-colons have a different meaning. Savannah bug #27497.
621 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
623 * configh.dos.template: Remove unconditional definition of
624 SYS_SIGLIST_DECLARED.
625 Include <sys/version.h> because ports of GCC 4.3.0 and later no
626 longer include it, so macros like __DJGPP_MINOR__ are no longer
627 defined automatically.
629 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
630 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
631 instead of using the hardcoded ones.
632 (SUBDIRS): doc subdir added.
633 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
634 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
635 create html formated docs. texi2html may not be ported to DOS.
636 (make.info, make.dvi, make.ps, make.html): Make targets depend on
637 'make.texi'.
638 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
639 -I switch to look in ./ instead of ./doc.
640 (html): Target depend on html-recursive instead of make_1.html.
641 (make_1.html): Removed.
642 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
643 (all-recursive): Allow for more than one subdir in the build
644 process.
645 (mostlyclean-recursive, clean-recursive, distclean-recursive)
646 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
647 (tags-recursive): Allow for more than one subdir in the build
648 process.
649 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
650 targets. Enter into doc/ to produce the targets.
651 (all-am): $(INFO_DEPS) replaced by info.
653 2009-09-26 Paul Smith <psmith@gnu.org>
655 * read.c (record_files): Use free_ns() to free struct nameseq.
656 (eval): Ditto.
658 * rule.c (freerule): Use free_dep_chain().
660 * read.c (record_files): Free FILENAMES chain for implicit rules.
661 (eval): Static pattern targets go into the string cache.
663 * function.c (string_glob): Free NAME in the nameseq chain.
665 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
667 * implicit.c (pattern_search): Terminate early if we haven't
668 found any rules to try (performance improvement).
670 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
672 * implicit.c (pattern_search): Merge three parallel arrays,
673 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
674 of struct TRYRULE. In the old version the latter two arrays
675 had insufficient length.
677 2009-09-24 Paul Smith <psmith@gnu.org>
679 * implicit.c (pattern_search): Add back support for order-only
680 prerequisites for secondary expansion implicit rules, that were
681 accidentally dropped. If we find a "|", enable order-only mode
682 and set IGNORE_MTIME on all deps that are seen afterward.
683 (pattern_search): Fix memory leaks: for intermediate files where
684 we've already set the file variable and pattern variable sets, be
685 sure to either save or free them as appropriate.
687 2009-09-23 Paul Smith <psmith@gnu.org>
689 Rework the way secondary expansion is stored, for efficiency.
690 This changes secondary expansion so that ONLY WHEN we know we have
691 a possibility of needing secondary expansion, do we defer the
692 secondary expansion. This means more parsing the deps but we use
693 a lot less memory (due to the strcache). Also, this fixes
694 Savannah bug #18622.
696 * read.c (eval): Don't parse the dep string here anymore.
697 (record_files): Take the dep argument as an unparsed string. If
698 secondary expansion is enabled AND the prereq string has a '$' in
699 it, then set NEED_2ND_EXPANSION and keep the entire string.
700 Otherwise, parse the dep string here to construct the dep list
701 with the names in the strcache.
703 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
704 duplicate the name string (others are in the strcache).
706 * implicit.c: Remove struct idep and free_idep_chain(): unused.
707 (struct patdeps): New structure to store prereq information.
708 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
709 which prerequisites need expansion, and expand only those.
711 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
712 and enter_prereqs(). split_prereqs() takes a fully-expanded string
713 and splits it into a DEP list, handling order-only prereqs.
714 (enter_prereqs): This function enters a list of DEPs into the file
715 database. If there's a stem defined, expand any pattern chars.
716 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
717 set. Use the above functions.
718 (snap_deps): Only perform second expansion on prereqs that need it,
719 as defined by the NEED_2ND_EXPANSION flag.
720 (print_prereqs): New function to print the prereqs
721 (print_file): Call print_prereqs() rather than print inline.
723 * hash.h (STRING_COMPARE): Take advantage of strcache() by
724 comparing pointers.
725 (STRING_N_COMPARE): Ditto.
726 (ISTRING_COMPARE): Ditto.
728 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
729 (parse_file_seq): Return void*
730 * read.c (parse_file_seq): Return void*.
731 (eval): Invoke macroized version of parse_file_seq()
732 * default.c (set_default_suffixes): Ditto.
733 * file.c (split_prereqs): Ditto.
734 * function.c (string_glob): Ditto.
735 * main.c (main): Ditto.
736 * rule.c (install_pattern_rule): Ditto.
738 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
740 2009-09-16 Paul Smith <psmith@gnu.org>
742 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
743 convert to macros.
744 * dep.h: Create alloc_dep() / free_dep() macros.
746 * implicit.c (pattern_search): Take advantage of the new
747 parse_file_seq() to add the directory prefix to each prereq.
749 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
750 all. Avoid reversing chains. Support adding prefixes.
751 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
752 cached/non-cached results.
753 (eval): Remove multi_glob() & invoke new parse_file_seq().
754 * rule.c (install_pattern_rule): Ditto.
755 * main.c (main): Ditto.
756 * implicit.c (pattern_search): Ditto.
757 * function.c (string_glob): Ditto.
758 * file.c (parse_prereqs): Ditto.
759 * default.c (set_default_suffixes): Ditto.
761 * variable.c (parse_variable_definition): Don't run off the end of
762 the string if it ends in whitespace (found with valgrind).
764 * commands.c (set_file_variables): Keep space for all targets in
765 $? if -B is given (found with valgrind).
767 2009-09-15 Paul Smith <psmith@gnu.org>
769 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
770 (xcalloc): Add new function.
771 * make.h: New declarations.
773 * ar.c (ar_glob_match): New calling method for concat().
774 * main.c (main): Ditto.
775 (decode_env_switches): Ditto.
776 * read.c (eval_makefile): Ditto.
777 (tilde_expand): Ditto.
778 (parse_file_seq): Ditto.
779 * variable.c (target_environment): Ditto.
780 (sync_Path_environment): Ditto.
782 * ar.c (ar_glob_match): Use xcalloc().
783 * dir.c (file_impossible): Ditto.
784 * file.c (enter_file): Ditto.
785 * job.c (new_job): Ditto.
786 * read.c (parse_file_seq): Ditto.
787 * vmsfunctions.c (opendir): Ditto.
789 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
791 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
792 inside the loop that looks up environment for PATH.
794 2009-08-31 Eli Zaretskii <eliz@gnu.org>
796 * function.c (windows32_openpipe): Update envp after calling
797 sync_Path_environment.
799 2009-08-02 Paul Smith <psmith@gnu.org>
801 * remake.c (notice_finished_file): Ensure file->cmds is not null
802 before looping through them. Fixes Savannah bug #21824.
804 * doc/make.texi (Wildcard Examples): Clarify when objects is
805 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
806 (Include): Clarify the behavior of -include.
807 Fixes Savannah bug #18963.
809 2009-08-01 Paul Smith <psmith@gnu.org>
811 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
812 etc. come on the command line. Fixes Savannah bug #27093.
814 * expand.c (expand_argument): If the argument is large enough use
815 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
817 * variable.c (do_variable_definition): Avoid using alloca() to
818 hold values, which can be large. Fixes Savannah bug #23960.
820 * job.c (new_job): Use memmove() instead of strcpy() since both
821 pointers are in the same memory block. Fixes Savannah bug #27148.
822 Patch by Petr Machata.
824 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
826 * job.c (construct_command_argv_internal): Add "ulimit" and
827 "unset" to the sh_cmds for Unixy shells.
829 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
831 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
832 that set make_cv_sys_gnu_glob, so they are also correctly set
833 when the cache has been populated before.
835 2009-07-04 Eli Zaretskii <eliz@gnu.org>
837 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
838 exist, as realpath(3) does where it's supported.
840 2006-07-04 Eli Zaretskii <eliz@gnu.org>
842 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
843 (abspath): Support systems that define HAVE_DOS_PATHS (have
844 drive letters in their file names). Use IS_PATHSEP instead of a
845 literal '/' comparison. Fixes Savannah bug #26886.
847 2009-06-14 Paul Smith <psmith@gnu.org>
849 * remake.c (update_file_1): Remember the original file we marked
850 as updating, so we can clear that flag again. If we find a target
851 via vpath, FILE might change.
852 (check_dep): Ditto. Fixes Savannah bug #13529.
853 Patch by Reid Madsen <reid.madsen@tek.com>.
855 2009-06-13 Paul Smith <psmith@gnu.org>
857 * doc/make.texi (MAKEFILES Variable): Be explicit that files
858 included by MAKEFILES cannot give default goals.
859 * read.c (eval): If set_default is not set, pass the no-default-goal
860 value when we read included makefiles. Fixes Savannah bug #13401.
862 * ar.c (ar_name): Ensure that targets with empty parens aren't
863 considered archive member references: archive members must have a
864 non-empty "member" string. Fixes Savannah bug #18435.
866 * function.c (string_glob): Rely on multi_glob() to determine
867 whether files exist or not. Remove call to file_exists_p() which
868 is not always correct. Fixes Savannah bug #21231.
869 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
870 then only files that really exist will be returned.
871 * dep.h: Add new argument to multi_glob().
872 * rule.c (install_pattern_rule): Ditto.
873 * read.c (eval): Ditto.
874 * main.c (main): Ditto.
875 * implicit.c (pattern_search): Ditto.
876 * file.c (parse_prereqs): Ditto.
877 * default.c (set_default_suffixes): Ditto.
879 2009-06-09 Paul Smith <psmith@gnu.org>
881 * commands.c (set_file_variables): If always_make_flag is set,
882 always add the prereq to $?. Fixes Savannah bug #17825.
884 * remake.c (update_file_1): When rebuilding deps of FILE, also try
885 to rebuild the deps of all the also_make targets for that file.
886 Fixes Savannah bug #19108.
888 * implicit.c (pattern_search): Undo test for is_target, added by
889 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
890 Rule Search Algorithm". Fixes Savannah bug #17752.
892 * main.c (clean_jobserver): Clear the jobserver_fds options and
893 set job_slots to the default when we clean up.
894 (define_makeflags): Return the new MAKEFLAGS value.
895 (main): Reset MAKEFLAGS in the environment when we re-exec.
896 Fixes Savannah bug #18124.
898 2009-06-08 Paul Smith <psmith@gnu.org>
900 * read.c (eval): Collapse continuations post-semicolon on target-
901 specific variables. Fixes Savannah bug #17521.
903 2009-06-07 Paul Smith <psmith@gnu.org>
905 * job.c (reap_children): For older systems without waitpid() (are
906 there any of these left?) run wait(2) inside EINTRLOOP to handle
907 EINTR errors. Fixes Savannah bug #16401.
909 * (various): Debug message cleanup. Fixes Savannah bug #16469.
911 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
913 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
914 not the end, to catch second expansion $(eval ...) defining new
915 target/prereq relationships during snap_deps.
916 Fixes Savannah bug #24622.
918 * read.c (record_files): The second-expansion "f->updating" hack
919 was not completely correct: if assumed that the target with
920 commands always had prerequisites; if one didn't then the ordering
921 was messed up. Fixed for now to use f->updating to decide whether
922 to preserve the last element in the deps list... but this whole
923 area of constructing and reversing the deps list is too confusing
924 and needs to be reworked. Fixes Savannah bug #21198.
926 2009-06-06 Paul Smith <psmith@gnu.org>
928 * hash.c (hash_insert): Remove useless test for NULL.
929 Fixes Savannah bug #21823.
931 * make.h: Move SET_STACK_SIZE determination to make.h.
932 * main.c (main): New global variable, STACK_LIMIT, holds the
933 original stack limit when make was started.
934 * job.c (start_job_command): Reset the stack limit, if we changed it.
935 Fixes Savannah bug #22010.
937 * remake.c (check_dep): Only set the target's state to not-started
938 if it's not already running. Found this while testing -j10 builds
939 of glibc: various targets were being rebuilt multiple times.
940 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
941 bug #15919.
943 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
944 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
945 Bugzilla bug 10246.
947 2009-06-04 Paul Smith <psmith@gnu.org>
949 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
951 * maintMakefile: Modify access of config and gnulib Savannah
952 modules to use GIT instead of CVS.
954 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
955 Fixes Savannah bug #24655.
957 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
958 this can happen during some invocations of $(eval ...) for example.
959 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
961 2009-06-02 Paul Smith <psmith@gnu.org>
963 * configure.in: Check for fileno()
964 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
965 for the makefile file so invocations of $(shell ...) don't inherit it.
966 Fixes Savannah bug #24277.
968 2009-06-01 Paul Smith <psmith@gnu.org>
970 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
971 expansion was handled incorrectly. Rework the default goal
972 handling to save the variable only. Remove default_goal_file and
973 default_goal_name.
974 * read.c (eval): Check default_goal_var, not default_goal_name.
975 * read.c (record_target_var): Don't check default_goal_file here.
977 2009-05-31 Paul Smith <psmith@gnu.org>
979 * main.c (main): Expand the .DEFAULT_GOAL variable before using
980 it, and if the multi_glob() returns nothing (say it expanded to
981 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
983 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
984 $(and ..) to the reference. Fixes Savannah bug #25694.
986 * make.1: Be clear that some recipes will be executed even with -n.
987 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
989 * doc/make.texi (Override Directive): Make more clear how
990 overrides and appends interact.
991 Elucidates part of Savannah bug #26207.
993 * read.c (record_target_var): Don't reset the origin on
994 target-specific variables; try_variable_definition() will handle
995 this correctly. Fixes Savannah bug #26207.
997 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
998 Fixes Savannah bug #25712.
1000 * implicit.c (pattern_search): Keep a pointer to the beginning of
1001 the filename and save that instead of the constructed pointer.
1002 Fixes Savannah bug #26593.
1003 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1005 2009-05-30 Paul Smith <psmith@gnu.org>
1007 * doc/make.texi (Multi-Line): Add a description of the new abilities
1008 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1009 "command sequence" vs. "recipe" syntax.
1010 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1011 after a define, to create variables with those flavors.
1013 2009-05-25 Paul Smith <psmith@gnu.org>
1015 Reworked the parser for variable assignments to allow multiple
1016 modifiers, and in any order. Also allows variable and
1017 prerequisites to be modifier names ('export', 'private', etc.)
1019 * NEWS: Add notes about user-visible changes.
1021 * read.c (struct vmodifiers): Remember what modifiers were seen.
1022 (parse_var_assignment): New function to parse variable assignments.
1023 (eval): Call the new function. Handle variable assignments earlier.
1025 * variable.c (parse_variable_definition): Only parse; don't create var.
1026 (assign_variable_definition): Call parse, then create the var.
1028 2009-05-24 Paul Smith <psmith@gnu.org>
1030 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1031 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1033 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1035 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1036 Fixes Savannah bug #25412.
1038 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1039 prototype for xmalloc.
1040 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1041 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1042 Loop over an array of extensions, instead of duplicating the same
1043 code inline. Use SearchPath followed by CreateFile, instead of
1044 the obsolete OpenFile. Fixes Savannah bug #17277.

1147 HAVE_DECL_SYS_SIGLIST.
1149 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1150 build does not use child_execute_job.
1152 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1153 export the SHELL environment variable to the child.
1155 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1157 * config.h.W32: Include sys/types.h.

1166 * doc/make.texi: Convert references to "commands", "command
1167 lines", and "command script" to "recipe".

1179 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1180 a more complex value than a simple shell: if it's not a default
1181 shell now then expand it and see if is a default shell then.
1183 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1185 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1186 pathnames, with const strings.
1187 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1192 * make.h: Add a prototype for w32_kill() (change suggested by

1209 * doc/make.texi (Special Variables): Moved this into the "How to
1210 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1215 (Rule Syntax): Ditto.
1216 (Command Syntax): Ditto.
1217 (Error Messages): Ditto.
1219 2007-09-10 Paul Smith <psmith@gnu.org>
1221 * commands.c (print_commands): Don't print an extra line in the
1222 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1224 * read.c (construct_include_path): Add the full string to the cache; we
1225 were chopping the last char.
1227 * NEWS: Announce the .RECIPEPREFIX special variable.
1228 * variable.c (lookup_special_var): Rename from handle_special_var().
1229 (lookup_variable): Call the new name.

1234 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1235 * main.c (main): Create the .RECIPEPREFIX special variable.
1236 * read.c (eval): Remove the cmd_prefix characters from the command
1237 scripts here, so they're not stored in the commands array at all,
1238 rather than waiting and stripping them out during command construction.
1239 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1241 2007-08-15 Paul Smith <psmith@gnu.org>
1243 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1244 file has had the section info removed, so add some to make.texi
1245 before we include it.
1247 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1249 * remake.c (check_dep): Reset the target state for intermediate
1250 files. They might have been considered before but not updated

1258 value of FLAGS.
1259 * job.c (construct_command_argv_internal): New argument FLAGS; all

1265 2007-07-13 Paul Smith <psmith@gnu.org>
1267 * file.c (expand_deps): Use variable_buffer as the start of the
1268 buffer, not the original pointer (in case it was reallocated).
1269 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1270 Fixes Savannah bug #20452.
1272 2007-07-04 Paul Smith <psmith@gnu.org>
1274 * (ALL FILES): Update to GPLv3.
1275 * (ALL FILES): Update copyright for 2007.

1286 "Expansion of a deferred"
1287 Fixes Savannah bug #20018.
1289 * expand.c (variable_expand_for_file): Preserve the value of
1290 reading_file rather than setting it to 0 at the end.

1293 2007-05-11 Paul Smith <psmith@gnu.org>
1295 * job.c (new_job): Add debug info to specify where make found the
1296 command script it is running to build a target.
1297 Fixes Savannah bug #18617.
1299 * default.c (default_suffixes,default_suffix_rules,default_variables):
1300 Add support for Objective C. Fixes Savannah bug #16389.
1301 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1303 * function.c (func_lastword): Initialize p.
1305 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1306 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1307 Dave Korn <dave.korn@artimi.com>
1309 2007-05-08 Paul Smith <psmith@gnu.org>
1311 Fix Savannah bug #19656:
1313 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1315 * make.h: Change all case-insensitive string compares to use
1316 strcasecmp() (from POSIX). If we don't have that but do have one
1317 of the others, define strcasecmp to be one of those instead. If
1318 we don't have any, declare a prototype for our own version.
1320 * misc.c (strcasecmp): Use this if we can't find any native
1321 case-insensitive string comparison function.
1322 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1323 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1324 strcmpi().
1325 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1326 strcasecmp() instead of stricmp().
1327 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1328 instead of strcmpi().
1329 * acinclude.m4: Remove the strcasecmp() check from here.
1331 2007-03-21 Paul Smith <psmith@gnu.org>
1333 * configure.in: Don't turn on case-insensitive file system support
1334 if --disable-... is given. Fixes Savannah bug #19348.
1336 2007-03-19 Paul Smith <psmith@gnu.org>
1338 * ALL: Use the strcache for all file name strings, or other
1339 strings which we will never free. The goal is to save memory by
1340 avoiding duplicate copies of strings. However, at the moment this
1341 doesn't save much memory in most situations: due to secondary
1342 expansion we actually save prerequisite lists twice (once before
1343 the secondary expansion, and then again after it's been parsed
1344 into individual file names in the dep list). We will resolve this
1345 in a future change, by doing the parsing up-front for targets
1346 where secondary expansion is not set.
1348 Moving things into the strcache also allows us to use const
1349 pointers in many more places.
1351 2007-01-03 Paul Smith <psmith@gnu.org>
1353 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1354 the function, not just the first. Fixes Savannah bug #18680.
1356 2006-11-18 Paul Smith <psmith@gnu.org>
1358 * strcache.c (strcache_add_len): Don't allocate a new buffer
1359 unless the string is not already nil-terminated. Technically this
1360 is a violation of the standard, since we may be passed an array
1361 that is not long enough to test one past. However, in make this
1362 is never true since we only use nil-terminated strings or
1363 sub-strings thereof.
1365 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1367 * main.c: New global cmd_prefix, defaults to '\t'.
1368 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1369 of '\t'.
1371 * dir.c: Constified.
1372 (dir_contents_file_exists_p): Check for an error return from
1373 readdir(), just in case.
1375 * commands.c: Constified.
1376 * default.c: Constified.
1377 * expand.c: Constified.
1378 * function.c: Partial constification.
1379 * variable.c: Partial constification.
1380 * vmsify.c: Constification. Hard to test this but I hope I didn't
1381 screw it up!
1382 * vpath.c: Partial constification.
1383 * w32/pathstuff.c: Partial constification.
1385 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1387 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1388 backslashes and drive letters as absolute.
1390 2006-10-22 Paul Smith <psmith@gnu.org>
1392 * main.c (struct command_switch): Use const and void*.
1394 2006-10-21 Paul Smith <psmith@gnu.org>
1396 * ar.c: Constified.
1397 * arscan.c: Constified.
1399 2006-09-30 Paul Smith <psmith@gnu.org>
1401 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1402 point to lastword since the example was updated.
1403 Fixes Savannah bug #16304.
1404 (Secondary Expansion): Correct example description.
1405 Fixes Savannah bug #16468.
1406 (Makefile Contents): Clarify that comments cannot appear within
1407 variable references or function calls.
1408 Fixes Savannah bug #16577.
1409 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1410 Fixes Savannah bug #17701.
1411 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1412 (Prerequisite Types): Added an example of using order-only
1413 prerequisites. Fixes Savannah bug #17880.
1414 (Rule Syntax): "lise" -> "list"
1415 (Multiple Rules): ... -> @dots{}
1416 (Splitting Lines): ditto.
1418 * remake.c (update_file_1): Prereqs that don't exist should be
1419 considered changed, for the purposes of $?.
1420 Fixes Savannah bug #16051.
1422 * make.1: Remove extraneous "+".
1423 Fixes Savannah bug #16652.
1425 2006-09-06 Paul D. Smith <psmith@gnu.org>

1432 $PATH_SEPARATOR.
1434 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1435 Normally, it is defined in config.h.
1437 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1438 well.
1440 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1441 sh_chars_sh for Windows platforms that emulate Unix.
1443 2006-05-07 Paul D. Smith <psmith@gnu.org>

1467 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1469 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1470 inner-scope variables don't mask outer-scope variables.
1472 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1473 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1474 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1475 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1476 values from memory allocation functions: they return void* and so
1477 don't need to be cast. Also remove (char *) casts of arguments to
1478 xrealloc().
1480 * configure.in: Remove checks for memcpy/memmove/strchr.
1482 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

1488 * variable.c, vpath.c: Ditto.
1490 * make.h (EXIT_FAILURE): Should be 1, not 0.
1492 2006-04-06 Paul D. Smith <psmith@gnu.org>
1494 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1495 require an ISO C 1989 standard compiler and runtime library.

1517 Remove update of make.texi from the list of things to do; we use
1518 version.texi now.
1520 2006-03-26 Paul D. Smith <psmith@gnu.org>
1522 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1523 support from automake, as described in the Texinfo manual.
1525 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1527 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1528 with lastslash, since the latter points to filename, not to
1529 target.
1530 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1531 Declare and define sh_chars_sh[].
1533 2006-03-23 Paul D. Smith <psmith@gnu.org>
1535 * configure.in: Look for build.sh.in in $srcdir so it will be
1536 built for remote configurations as well.
1538 * Makefile.am: Make sure to clean up build.sh during distclean.
1539 Fixes Savannah bug #16166.
1541 * misc.c (log_access): Takes a const char *.

1556 * README.cvs: Add information on steps for making a release (to
1557 make sure I don't forget any).
1559 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1560 function.
1561 (die): Cleanup code was removed from here; call the new function.
1562 (main): If we are re-execing, clean up the jobserver first so we
1563 don't leak file descriptors.
1564 Reported by Craig Fithian <craig.fithian@citigroup.com>
1566 2006-03-17 Paul D. Smith <psmith@gnu.org>
1568 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1569 allow multiple concurrent runs.
1570 Patch from Joseph Myers <joseph@codesourcery.com>
1572 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1574 * dep.h (struct dep): Add the stem field.
1575 * misc.c (alloc_dep, free_dep): New functions.
1576 (copy_dep_chain): Copy stem.
1577 (free_dep_chain): Use free_dep.
1578 * read.c (record_files): Store stem in the dependency line.
1579 * file.c (expand_deps): Use stem stored in the dependency line. Use
1580 free_dep_chain instead of free_ns_chain.
1581 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1582 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1583 * main.c (main, handle_non_switch_argument): Ditto.
1584 * remake.c (check_dep): Ditto.
1585 * rule.c (convert_suffix_rule, freerule): Ditto.
1587 2006-03-14 Paul D. Smith <psmith@gnu.org>
1589 * expand.c (variable_append): Instead of appending everything then
1590 expanding the result, we expand (or not, if it's simple) each part
1591 as we add it.
1592 (allocated_variable_append): Don't expand the final result.
1593 Fixes Savannah bug #15913.
1595 2006-03-09 Paul Smith <psmith@gnu.org>
1597 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1598 listed non-existent files as changed. Turns out there's a bug in
1599 the Linux kernel builds which means that this change causes
1600 everything to rebuild every time. We will re-introduce this fix
1601 in the next release, to give them time to fix their build system.
1602 Fixes Savannah bug #16002.
1603 Introduces Savannah bug #16051.
1605 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1606 we *don't* find UNIX "/".
1607 Reported by David Ergo <david.ergo@alterface.com>
1609 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1611 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1612 locator function find_and_set_default_shell if SHELL came from the
1613 command line.
1615 2006-02-20 Paul D. Smith <psmith@gnu.org>
1617 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1618 to be null; don't core in that case.
1620 2006-02-19 Paul D. Smith <psmith@gnu.org>
1622 * commands.c (set_file_variables): Realloc, not malloc, the static
1623 string values to avoid memory leaks.
1625 * expand.c (recursively_expand_for_file): Only set reading_file to
1626 an initialized value.
1628 * implicit.c (pattern_search): We need to make a copy of the stem
1629 if we get it from an intermediate dep, since those get freed.
1631 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1632 begin with ".".
1633 (enter_file) [VMS]: Ditto.
1634 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1636 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1638 * job.c (construct_command_argv_internal): Fix last change.
1640 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1641 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1642 the calls to _beginthreadex.
1644 * expand.c (recursively_expand_for_file): Initialize `save' to
1645 prevent compiler warnings.
1647 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1649 * job.c (construct_command_argv_internal): Don't create a temporary
1650 script/batch file if we are under -n. Call _setmode to switch the
1651 script file stream to text mode.
1653 2006-02-17 Paul D. Smith <psmith@gnu.org>
1655 * variable.c (merge_variable_set_lists): Don't try to merge the
1656 global_setlist. Not only is this useless, but it can lead to
1657 circularities in the linked list, if global_setlist->next in one
1658 list gets set to point to another list which also ends in
1659 global_setlist.
1660 Fixes Savannah bug #15757.
1662 2006-02-15 Paul D. Smith <psmith@gnu.org>
1664 Fix for Savannah bug #106.
1666 * expand.c (expanding_var): Keep track of which variable we're
1667 expanding. If no variable is being expanded, it's the same as
1668 reading_file.
1669 * make.h (expanding_var): Declare it.
1670 * expand.c (recursively_expand_for_file): Set expanding_var to the
1671 current variable we're expanding, unless there's no file info in
1672 it (could happen if it comes from the command line or a default
1673 variable). Restore it before we exit.
1674 * expand.c (variable_expand_string): Use the expanding_var file
1675 info instead of the reading_file info.
1676 * function.c (check_numeric): Ditto.
1677 (func_word): Ditto.
1678 (func_wordlist): Ditto.
1679 (func_error): Ditto.
1680 (expand_builtin_function): Ditto.
1681 (handle_function): Ditto.
1683 2006-02-14 Paul D. Smith <psmith@gnu.org>
1685 * read.c (eval): Even if the included filenames expands to the
1686 empty string we still need to free the allocated buffer.
1688 * implicit.c (pattern_search): If we allocated a variable set for
1689 an impossible file, free it.
1690 * variable.c (free_variable_set): New function.
1691 * variable.h: Declare it.
1693 * read.c (read_all_makefiles): Makefile names are kept in the
1694 strcache, so there's never any need to alloc/free them.
1695 (eval): Ditto.
1697 * main.c (main): Add "archives" to the .FEATURES variable if
1698 archive support is enabled.
1699 * doc/make.texi (Special Variables): Document it.
1701 2006-02-13 Paul D. Smith <psmith@gnu.org>
1703 * implicit.c (pattern_search): Add checking for DOS pathnames to
1704 the pattern rule target LASTSLASH manipulation.
1705 Fixes Savannah bug #11183.
1707 2006-02-11 Paul D. Smith <psmith@gnu.org>
1709 * (ALL FILES): Updated copyright and license notices.
1711 2006-02-10 Paul D. Smith <psmith@gnu.org>
1713 A new internal capability: the string cache is a read-only cache
1714 of strings, with a hash table interface for fast lookup. Nothing
1715 in the cache will ever be freed, so there's no need for reference
1716 counting, etc. This is the beginning of a full solution for
1717 Savannah bug #15182, but for now we only store makefile names here.
1719 * strcache.c: New file. Implement a read-only string cache.
1720 * make.h: Add prototypes for new functions.
1721 * main.c (initialize_global_hash_tables): Initialize the string cache.
1722 (print_data_base): Print string cache stats.
1723 * read.c (eval_makefile): Use the string cache to store makefile
1724 names. Rewrite the string allocation to be sure we free everything.
1726 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1728 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1729 directory time stamp didn't change, except on FAT filesystems.
1730 Suggested by J. David Bryan <jdbryan@acm.org>.
1732 2006-02-09 Paul D. Smith <psmith@gnu.org>
1734 * function.c (func_or): Implement a short-circuiting OR function.
1735 (func_and): Implement a short-circuiting AND function.
1736 (function_table_init): Update the table with the new functions.
1737 * doc/make.texi (Conditional Functions): Changed the "if" section
1738 to one on general conditional functions. Added documentation for
1739 $(and ...) and $(or ...) functions.
1740 * NEWS: Note new $(and ...) and $(or ...) functions.
1742 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1744 * job.h (struct child): Add the dontcare bitfield.
1745 * job.c (new_job): Cache dontcare flag.
1746 * job.c (reap_children): Use cached dontcare flag instead of the
1747 one in struct file. Fixes Savannah bug #15641.
1749 2006-02-06 Paul D. Smith <psmith@gnu.org>
1751 * vpath.c (selective_vpath_search): If the file we find has a
1752 timestamp from -o or -W, use that instead of the real time.
1753 * remake.c (f_mtime): If the mtime is a special token from -o or
1754 -W, don't overwrite it with the real mtime.
1755 Fixes Savannah bug #15341.
1757 Updates from Markus Mauhart <qwe123@chello.at>:
1759 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1760 (process_signal, process_last_err, process_exit_code): Manage
1761 invalid handle values.
1762 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1763 manage invalid handles; remove them.
1764 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1765 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1766 * README.cvs: Updates for building from CVS.
1768 2006-02-05 Paul D. Smith <psmith@gnu.org>
1770 * file.c (enter_file): Keep track of the last double_colon entry,
1771 to avoid walking the list every time we want to add a new one.
1772 Fixes Savannah bug #15533.
1773 * filedef.h (struct file): Add a new LAST pointer.
1775 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1776 the comparison. For 64-bits systems the result of the subtraction
1777 might not fit into an int. Use comparison instead.
1778 Fixes Savannah bug #15534.
1780 * doc/make.texi: Update the chapter on writing commands to reflect
1781 the changes made in 3.81 for backslash/newline and SHELL handling.
1783 2006-02-01 Paul D. Smith <psmith@gnu.org>
1785 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1786 variable st is not used when it's not initialized.
1787 Patch from Eli Zaretskii <eliz@gnu.org>.
1789 2006-01-31 Paul D. Smith <psmith@gnu.org>

1795 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1796 J. Grant <jg@jguk.org>.
1798 * main.c: Update the copyright year in the version output.
1799 * prepare_w32.bat: Remove this file from the distribution.
1801 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1803 * remake.c (update_goal_chain): Set g->changed instead of
1804 incrementing it, as it is only 8-bit wide, and could overflow if
1805 many commands got started in update_file.
1807 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1809 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1810 MAXIMUM_WAIT_OBJECTS.
1811 (process_wait_for_any_private): Change dimension of handles[]
1812 array to MAXIMUM_WAIT_OBJECTS.
1813 (process_used_slots): New function.
1814 (process_register): Don't register more processes than the
1815 available number of slots.
1816 (process_easy): Don't start new processes if all slots are used up.
1818 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1819 are already more children than sub_proc.c can handle, behave as if
1820 the load were too high.
1821 (start_job_command): Fix a typo in error message when process_easy
1822 fails.
1824 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1826 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1827 the shell is not sh.exe.
1829 * job.c (create_batch_file): Renamed from create_batch_filename;
1830 all callers changed. Don't close the temporary file; return its
1831 file descriptor instead. New arg FD allows to return the file
1832 descriptor.
1833 (construct_command_argv_internal): Use _fdopen instead of fopen to
1834 open the batch file.
1836 2006-01-04 Paul D. Smith <psmith@gnu.org>
1838 * readme.vms: Updates for case-insensitive VMS file systems from
1839 Hartmut Becker <Hartmut.Becker@hp.com>.
1840 * dir.c (vms_hash): Ditto.
1841 * vmsify.c (copyto): Ditto.
1842 * vmsfunctions.c (readdir): Ditto.
1844 * make.1: Add a section on the exit codes for make.

1851 doesn't exist.
1853 * read.c (eval): Be sure to strip off trailing whitespace from the
1854 prerequisites list properly. Also, initialize all fields in
1855 struct dep when creating a new one.
1857 2005-12-28 Paul D. Smith <psmith@gnu.org>
1859 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1860 disable warnings for MSC.
1861 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1863 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1865 * doc/make.texi (Execution): Add a footnote about changes in
1866 handling of backslash-newline sequences. Mention the differences
1867 on MS-DOS and MS-Windows.
1869 * NEWS: More details about building the MinGW port and a pointer
1870 to README.W32. Fix the section name that describes the new
1871 backward-incompatible processing of backslash-newline sequences.
1872 The special processing of SHELL set to "cmd" is only relevant to
1873 MS-Windows, not MS-DOS.
1875 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1877 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1878 to DWORD, to avoid compiler warnings.
1879 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1880 use %ld in format, to avoid compiler warnings.
1882 * doc/make.texi (Special Targets): Fix a typo.
1883 (Appending): Fix cross-reference to Setting.
1884 (Special Variables, Secondary Expansion, File Name Functions)
1885 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1886 periods after a sentence.
1887 (Execution): Add @: after "e.g.".
1888 (Environment): Fix punctuation.
1889 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1890 (Shell Function, Target-specific): Add @: after "vs."
1892 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1894 * read.c (record_target_var): Initialize variable's export field
1895 with v_default instead of leaving it "initialized" by whatever
1896 garbage happened to be on the heap.
1898 2005-12-12 Paul D. Smith <psmith@gnu.org>
1900 * make.1: Fix some display errors and document all existing options.
1901 Patch by Mike Frysinger <vapier@gentoo.org>.
1903 2005-12-11 Paul D. Smith <psmith@gnu.org>
1905 * implicit.c (pattern_search): If 2nd expansion is not set for
1906 this implicit rule, replace the pattern with the stem directly,
1907 and don't re-expand the variable list. Along with the other
1908 .SECONDEXPANSION changes below, fixes bug #13781.
1910 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1912 * implicit.c (pattern_search): Mark other files that this rule
1913 builds as targets so that they are not treated as intermediates
1914 by the pattern rule search algorithm. Fixes bug #13022.
1916 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1918 * remake.c (notice_finished_file): Propagate the change of
1919 modification time to all the double-colon entries only if
1920 it is the last one to be updated. Fixes bug #14334.
1922 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1924 * function.c (func_flavor): Implement the flavor function which
1925 returns the flavor of a variable.
1926 * doc/make.texi (Functions for Transforming Text): Document it.
1927 * NEWS: Add it to the list of new functions.
1929 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1931 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1932 variable.
1933 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1934 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1936 2005-10-26 Paul Smith <psmith@gnu.org>
1938 * read.c (record_files): Don't set deps flags if there are no deps.
1939 * maintMakefile: We only need to build the templates when we are
1940 creating a distribution, so don't do it for "all".
1942 2005-10-24 Paul D. Smith <psmith@gnu.org>
1944 Make secondary expansion optional: its enabled by declaring the
1945 special target .SECONDEXPANSION.
1947 * NEWS: Update information on second expansion capabilities.
1948 * doc/make.texi (Secondary Expansion): Document the
1949 .SECONDEXPANSION special target and its behavior.

1951 prerequisite list was found in a static pattern rule.
1952 (free_dep_chain): Declare a prototype.
1953 * file.c (parse_prereqs): New function: break out some complexity
1954 from expand_deps().
1955 (expand_deps): If we aren't doing second expansion, replace % with
1956 the stem for static pattern rules. Call the new function.
1957 * filedef.h (parse_prereqs): Declare a prototype.
1958 * implicit.c (pattern_search): Initialize the new staticpattern
1959 field.
1960 * main.c (second_expansion): Declare a global variable to remember
1961 if the special target has been seen. Initialize the new
1962 staticpattern field for prerequisites.
1963 * make.h: Extern for second_expansion.
1964 * misc.c (free_dep_chain): New function: frees a struct dep list.
1965 * read.c (read_all_makefiles): Initialize the staticpattern field.
1966 (eval_makefile): Ditto.
1967 (record_files): Check for the .SECONDEXPANSION target and set
1968 second_expansion global if it's found.
1969 Use the new free_dep_chain() instead of doing it by hand.
1970 Set the staticpattern field for prereqs of static pattern targets.
1972 2005-10-16 Paul D. Smith <psmith@gnu.org>
1974 * main.c (main): Set CURDIR to be a file variable instead of a
1975 default, so that values of CURDIR inherited from the environment
1976 won't override the make value.
1978 2005-09-26 Paul D. Smith <psmith@gnu.org>
1980 * job.c (construct_command_argv_internal): If the line is empty
1981 remember to free the temporary argv strings.
1982 Fixes bug # 14527.
1984 2005-09-16 Paul D. Smith <psmith@gnu.org>
1986 * job.c (start_job_command): The noerror flag is a boolean (single
1987 bit); set it appropriately.
1988 Reported by Mark Eichin <eichin@metacarta.com>
1990 2005-08-29 Paul D. Smith <psmith@gnu.org>
1992 * function.c (func_error): On Windows, output from $(info ...)
1993 seems to come in the wrong order. Try to force it with fflush().
1995 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1997 * read.c (record_files): Move code that sets stem for static
1998 pattern rules out of the if (!two_colon) condition so it is
1999 also executed for two-colon rules. Fixes Savannah bug #13881.
2001 2005-08-08 Paul D. Smith <psmith@gnu.org>
2003 * make.h: Don't test that __STDC__ is non-0. Some compilers
2004 (Windows for example) set it to 0 to denote "ISO C + extensions".
2005 Fixes bug # 13594.
2007 2005-08-07 Paul D. Smith <psmith@gnu.org>
2009 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2010 conditional (slightly different version of a fix from Eli).
2012 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2013 If make is running in parallel without -k and two jobs die in a
2014 row, but not too close to each other, then make will quit without
2015 waiting for the rest of the jobs to die.
2017 * main.c (die): Don't reset err before calling reap_children() the
2018 second time: we still want it to be in the error condition.
2019 * job.c (reap_children): Use a static variable, rather than err,
2020 to control whether or not the error message should be printed.
2022 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2024 * w32/subproc/sub_proc.c: Include signal.h.
2025 (process_pipe_io, process_file_io): Pass a pointer to a local
2026 DWORD variable to GetExitCodeProcess. If the exit code is
2027 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2029 * job.c [WINDOWS32]: Include windows.h.
2030 (main_thread) [WINDOWS32]: New global variable.
2031 (reap_children) [WINDOWS32]: Get the handle for the main thread
2032 and store it in main_thread.
2034 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2035 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2036 doing anything else. When we are done, close the main thread
2037 handle and exit with status 130.
2039 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2041 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2042 pointer to fprintf.
2044 * main.c (find_and_set_default_shell): If found a DOSish shell,
2045 set sh_found and the value of default_shell, and report the
2046 findings in debug mode.
2048 * job.c (construct_command_argv_internal): Check unixy_shell, not
2049 no_default_sh_exe, to decide whether to use Unixy or DOSish
2050 builtin commands.
2052 * README.W32: Update with info about the MinGW build.
2054 * build_w32.bat: Support MinGW.
2056 * w32/subproc/build.bat: Likewise.
2058 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2059 printing DWORD args.
2061 * function.c (windows32_openpipe): Fix format strings for printing
2062 DWORD args.
2064 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2065 'reap_mode'.
2066 (start_job_command): Fix format string for printing the result of
2067 process_easy.
2068 (start_job_command) [WINDOWS32]: Do not define.
2069 (exec_command): Fix format string for printing HANDLE args.
2071 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2072 to avoid compiler warnings.
2073 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2074 (Note: some of these fixes were submitted independently by J. Grant)
2076 2005-07-30 J. Grant <jg@jguk.org>
2078 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2079 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2080 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2082 2005-07-15 Paul Smith <psmith@gnu.org>
2084 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2085 we don't have a POSIX shell, then revert to the old
2086 backslash-newline behavior (where they are stripped).
2087 Fixes bug #13665.
2089 2005-07-08 Paul D. Smith <psmith@gnu.org>
2091 * config.h.W32.template: Reorder to match the standard config.h,
2092 for easier comparisons.
2093 From J. Grant <jg@jguk.org>
2095 * maintMakefile: Remove .dep_segment before overwriting it, in
2096 case it's not writable or noclobber is set.
2097 * expand.c (variable_expand_string): Cast result of pointer
2098 arithmetic to avoid a warning.
2099 * main.c (switches): Add full-fledged final initializer.
2101 2005-07-06 Paul D. Smith <psmith@gnu.org>
2103 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2104 * signame.c (strsignal): If we found _sys_siglist[] or
2105 __sys_siglist[] use those instead of sys_siglist[].
2106 From Albert Chin <china@thewrittenword.com>
2108 2005-07-04 Paul D. Smith <psmith@gnu.org>
2110 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2111 globfree(); set up to use the GNU versions.
2112 From Martin Zinser <zinser@zinser.no-ip.info>
2114 2005-07-03 Paul D. Smith <psmith@gnu.org>
2116 From J. Grant <jg@jguk.org>:
2118 * README.W32.template: Update the Windows and tested MSVC versions.
2119 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2120 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2121 * build_w32.bat: Ditto.
2122 * w32/subproc/build.bat: Ditto.
2124 2005-06-28 Paul D. Smith <psmith@gnu.org>
2126 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2127 declaration was checked but not present.
2129 2005-06-27 Paul D. Smith <psmith@gnu.org>
2131 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2132 to unsigned long. Fixes Savannah bug #13550.
2134 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2135 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2136 Fixes Savannah bug #13551.
2138 2005-06-26 Paul D. Smith <psmith@gnu.org>
2140 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2141 it if ANSI_STRING is not set.
2143 2005-06-25 Paul D. Smith <psmith@gnu.org>
2145 * read.c (eval): If no filenames are passed to any of the
2146 "include" variants, don't print an error.
2147 * doc/make.texi (Include): Document this.
2148 Fixes Savannah bug #1761.
2150 * job.c (construct_command_argv_internal): Sanitize handling of
2151 backslash/newline pairs according to POSIX: that is, keep the
2152 backslash-newline in the command script, but remove a following
2153 TAB character, if present. In the fast path, make sure that the
2154 behavior matches what the shell would do both inside and outside
2155 of quotes. In the slow path, quote the backslash and put a
2156 literal newline in the string.
2157 Fixes Savannah bug #1332.
2158 * doc/make.texi (Execution): Document the new behavior and give
2159 some examples.
2160 * NEWS: Make a note of the new behavior.
2162 * make.h [WINDOWS32]: #include <direct.h>.
2163 Fixes Savannah bug #13478.
2165 * remake.c (name_mtime): If the stat() of a file fails and the -L
2166 option was given and the file is a symlink, take the best mtime of
2167 the symlink we can get as the mtime of the file and don't fail.
2168 Fixes Savannah bug #13280.
2170 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2171 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2172 inside a variable reference. Make this function static as it's
2173 only used here.
2174 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2175 parsing an unexpanded line looking for semicolons.
2176 Fixes Savannah bug #1454.
2177 * misc.c (remove_comments): Move this to read.c and make it static
2178 as it's only used there. Call find_char_unquote() with new arg.
2179 * make.h: Remove prototypes for find_char_unquote() and
2180 remove_comments() since they're static now.
2182 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2183 its export flag and obtain its value. When we need to re-exec,
2184 increment the value and add it into the environment.
2185 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2186 * NEWS: Mention MAKE_RESTARTS.
2187 * main.c (always_make_set): New variable. Change the -B option to
2188 set this one instead.
2189 (main): When checking makefiles, only set always_make_flag if
2190 always_make_set is set AND the restarts flag is 0. When building
2191 normal targets, set it IFF always_make_set is set.
2192 (main): Avoid infinite recursion with -W, too: only set what-if
2193 files to NEW before we check makefiles if we've never restarted
2194 before. If we have restarted, set what-if files to NEW _after_ we
2195 check makefiles.
2196 Fixes Savannah bug #7566:
2198 2005-06-17 Paul D. Smith <psmith@gnu.org>
2200 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2201 in the prerequisites list.
2203 2005-06-12 Paul D. Smith <psmith@gnu.org>
2205 Fix Savannah bug # 1328.
2207 * configure.in: Check for atexit().
2208 * misc.c (close_stdout): Test stdout to see if writes to it have
2209 failed. If so, be sure to exit with a non-0 error code. Based on
2210 code found in gnulib.
2211 * make.h: Prototype.
2212 * main.c (main): Install close_stdout() with atexit().
2214 2005-06-10 Paul D. Smith <psmith@gnu.org>
2216 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2218 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2219 headers; make vmsWaitForChildren() static; extern vmsify().
2220 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2221 Don't create child_execute_job() here (it's in vmsjobs.c).
2222 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2224 2005-06-09 Paul D. Smith <psmith@gnu.org>
2226 * variable.c (push_new_variable_scope): File variables point
2227 directly to the global_setlist variable. So, inserting a new
2228 scope in front of that has no effect on those variables: they
2229 don't go through current_variable_set_list. If we're pushing a
2230 scope and the current scope is global, push it "the other way" so
2231 that the new setlist is in the global_setlist variable, and
2232 next points to a new setlist with the global variable set.
2233 (pop_variable_scope): Properly undo a push with the new
2234 semantics.
2235 Fixes Savannah bug #11913.
2237 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2239 * job.c (reap_children): Don't die of the command failed but
2240 the dontcare flag is set. Fixes Savannah bug #13216.
2242 * implicit.c (pattern_search): When creating a target from
2243 an implicit rule match, lookup pattern target and set precious
2244 flag in a newly created target. Fixes Savannah bug #13218.
2246 2005-05-13 Paul D. Smith <psmith@gnu.org>
2248 Implement "if... else if... endif" syntax.
2250 * read.c (eval): Push all checks for conditional words ("ifeq",
2251 "else", etc.) down into the conditional_line() function.
2252 (conditional_line): Rework to allow "else if..." clause. New
2253 return value -2 for lines which are not conditionals. The
2254 ignoring flag can now also be 2, which means "already parsed a
2255 true branch". If that value is seen no other branch of this
2256 conditional can be considered true. In the else parsing if there
2257 is extra text after the else, invoke conditional_line()
2258 recursively to see if it's another conditional. If not, it's an
2259 error. If so, raise the conditional value to this level instead
2260 of creating a new conditional nesting level. Special check for
2261 "else" and "endif", which aren't allowed on the "else" line.
2262 * doc/make.texi (Conditional Syntax): Document the new syntax.
2264 2005-05-09 Paul D. Smith <psmith@gnu.org>
2266 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2267 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2268 recurses to the w32 directory, even on non-Windows systems. Use
2269 the method suggested in the automake manual.
2270 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2271 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2273 2005-05-07 Paul D. Smith <psmith@gnu.org>
2275 * main.c (die): If we're dying with a fatal error (not that a
2276 command has failed), write back any leftover tokens before we go.
2278 * job.c (set_child_handler_action_flags): If there are jobs
2279 waiting for the load to go down, set an alarm to go off in 1
2280 second. This allows us to wake up from a potentially long-lasting
2281 read() and start a new job if the load has gone down. Turn it off
2282 after the read.
2283 (job_noop): Dummy signal handler function.
2284 (new_job): Invoke it with the new semantics.
2286 * docs/make.texi: Document secondary expansion. Various cleanups
2287 and random work.
2289 2005-05-03 Paul D. Smith <psmith@gnu.org>
2291 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2292 the targets which are to ultimately be made are called "goals";
2293 see the GNU make manual. Also, MAKECMDGOALS, etc.
2295 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2296 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2297 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2299 2005-05-02 Paul D. Smith <psmith@gnu.org>
2301 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2302 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2303 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2304 functions to vmsjobs.c. #include it into jobs.c.
2306 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2307 jobserver tokens. I found that this happens when an exported
2308 recursive variable contains a $(shell ...) function reference: in
2309 this situation we could "forget" to write back a token.
2311 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2312 we have. It's not reliable to depend on the number of children in
2313 our linked list so keep a separate count.
2314 (new_job): Check jobserver_tokens rather than children &&
2315 waiting_jobs. Increment jobserver_tokens when we get one.
2316 (free_child): If jobserver_tokens is 0, internal error. If it's
2317 >1, write a token back to the jobserver pipe (we don't write a
2318 token for the "free" job). Decrement jobserver_tokens.
2320 * main.c: Add variable master_job_slots.
2321 (main): Set it to hold the number of jobs requested if we're the
2322 master process, when using the jobserver.
2323 (die): Sanity checks: first test jobserver_tokens to make sure
2324 this process isn't holding any tokens we didn't write back.
2325 Second, if master_job_slots is set count the tokens left in the
2326 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2328 2005-04-24 Paul D. Smith <psmith@gnu.org>
2330 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2331 with -l# can lose jobserver tokens, because waiting jobs are not
2332 consulted properly when checking for the "free" token.
2334 * job.c (free_child): Count waiting_jobs as having tokens.
2335 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2336 handle jobs waiting for the load to drop.
2338 2005-04-23 Paul D. Smith <psmith@gnu.org>
2340 * main.c (main): Be careful to not core if a variable setting in
2341 the environment doesn't contain an '='. This is illegal but can
2342 happen in broken setups.
2343 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2345 2005-04-12 Paul D. Smith <psmith@gnu.org>
2347 The second expansion feature causes significant slowdown. Timing
2348 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2349 read the makefile before the feature, to 11+s to do the same
2350 operations after the feature. Additionally, memory usage
2351 increased drastically. To fix this I added some intelligence that
2352 avoids the overhead of the second expansion unless it's required.
2354 * dep.h: Add a new boolean field, need_2nd_expansion.
2356 * read.c (eval): When creating the struct dep for the target,
2357 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2358 (record_files): If there's a "%" in a static pattern rule, it gets
2359 converted to "$*" so set need_2nd_expansion to 1.
2361 * file.c (expand_deps): Rework to be more efficient. Only perform
2362 initialize_file_variables(), set_file_variables(), and
2363 variable_expand_for_file() if the need_2nd_expansion is set.
2365 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2366 (pattern_search): Ditto.
2367 * main.c (handle_non_switch_argument): Ditto.
2368 (main): Ditto.
2369 * read.c (read_all_makefiles): Ditto.
2370 (eval_makefile): Ditto.
2372 2005-04-07 Paul D. Smith <psmith@gnu.org>
2374 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2375 * variable.c (sync_Path_environment): Ditto.
2376 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2378 * main.c (main): Define the .FEATURES variable.
2379 * NEWS: Announce .FEATURES.
2380 * doc/make.texi (Special Variables): Document .FEATURES.
2382 * remake.c (check_dep): If a file is .PHONY, update it even if
2383 it's marked intermediate. Fixes Savannah bug #12331.
2385 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2387 * file.c (expand_deps): Factor out the second expansion and
2388 prerequisite line parsing logic from snap_deps().
2390 * file.c (snap_deps): Use expand_deps(). Expand and parse
2391 prerequisites of the .SUFFIXES special target first. Fixes
2392 Savannah bug #12320.
2394 2005-03-13 Paul D. Smith <psmith@gnu.org>
2396 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2397 Zaretskii.
2399 2005-03-11 Paul D. Smith <psmith@gnu.org>
2401 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2402 available, not undefined (from Earnie Boyd).
2404 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2406 * implicit.c (pattern_search): Mark an intermediate target as
2407 precious if it happened to be a prerequisite of some (other)
2408 target. Fixes Savannah bug #12267.
2410 2005-03-09 Paul D. Smith <psmith@gnu.org>
2412 * read.c (eval_makefile): Add alloca(0).
2413 (eval_buffer): Ditto.
2415 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2417 * main.c (main): Use o_file instead of o_default when defining
2418 the .DEFAULT_TARGET special variable.
2419 * read.c (eval): Use define_variable_global() instead of
2420 define_variable() when setting new value for the .DEFAULT_TARGET
2421 special variable. Fixes Savannah bug #12266.
2423 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2425 * imlicit.c (pattern_search): Mark files for which an implicit
2426 rule has been found as targets. Fixes Savannah bug #12202.
2428 2005-03-04 Paul D. Smith <psmith@gnu.org>
2430 * AUTHORS: Update.
2431 * doc/make.texi (Automatic Variables): Document $|.
2433 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2435 * read.c (record_files): Instead of substituting % with
2436 actual stem value in dependency list replace it with $*.
2437 This fixes stem triple expansion bug.
2439 * implicit.c (pattern_search): Copy stem to a separate
2440 buffer and make it a properly terminated string. Assign
2441 this buffer instead of STEM (which is not terminated) to
2442 f->stem. Instead of substituting % with actual stem value
2443 in dependency list replace it with $*. This fixes stem
2444 triple expansion bug.
2446 2005-03-01 Paul D. Smith <psmith@gnu.org>
2448 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2449 on Windows, as it takes a handle not a pid. Just exit.
2450 Fix from patch #3679, provided by Alessandro Vesely.
2452 * configure.in: Update check for sys_siglist[] from autoconf manual.
2453 * signame.c (strsignal): Update to use the new autoconf macro.
2455 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2457 * read.c (record_files): Add a check for the list of prerequisites
2458 of a static pattern rule being empty. Fixes Savannah bug #12180.
2460 2005-02-28 Paul D. Smith <psmith@gnu.org>
2462 * doc/make.texi (Text Functions): Update docs to allow the end
2463 ordinal for $(wordlist ...) to be 0.
2464 * function.c (func_wordlist): Fail if the start ordinal for
2465 $(wordlist ...) is <1. Matches documentation.
2466 Resolves Savannah support request #103195.
2468 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2469 previously we were stopping when !-q, exactly the opposite. This
2470 has been wrong since version 1.34, in 1994!
2471 (update_file): If we got an error don't break out to run more
2472 double-colon rules: just return immediately.
2473 Fixes Savannah bug #7144.
2475 2005-02-27 Paul D. Smith <psmith@gnu.org>
2477 * misc.c (end_of_token): Make argument const.
2478 * make.h: Update prototype.
2480 * function.c (abspath, func_realpath, func_abspath): Use
2481 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2482 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2483 * read.c (record_files): Ditto.
2484 * variable.c (do_variable_definition): Ditto.
2486 * function.c (func_error): Create a new function $(info ...) that
2487 simply prints the message to stdout with no extras.
2488 (function_table_init): Add new function to the table.
2489 * NEWS: Add $(info ...) reference.
2490 * doc/make.texi (Make Control Functions): Document it.
2492 New feature: if the system supports symbolic links, and the user
2493 provides the -L/--check-symlink-time flag, then use the latest
2494 mtime between the symlink(s) and the target file.
2496 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2497 readlink(). If both are available, define MAKE_SYMLINKS.
2498 * main.c: New variable: check_symlink_flag.
2499 (usage): Add a line for -L/--check-symlink-times to the help string.
2500 (switches): Add -L/--check-symlink-times command line argument.
2501 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2502 print a warning and disable it again.
2503 * make.h: Declare check_symlink_flag.
2504 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2505 if the file is a symlink then check each link in the chain and
2506 choose the NEWEST mtime we find as the mtime for the file. The
2507 newest mtime might be the file itself!
2508 * NEWS: Add information about this new feature.
2509 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2511 Avoid core dumps described in Savannah bug # 12124:
2513 * file.c: New variable snapped_deps remember whether we've run
2514 snap_deps().
2515 (snap_deps): Set it.
2516 * filedef.h: Extern it.
2517 * read.c (record_files): Check snapped_deps; if it's set then
2518 we're trying to eval a new target/prerequisite relationship from
2519 within a command script, which we don't support. Fatal.
2521 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2523 Implementation of the .DEFAULT_TARGET special variable.
2525 * read.c (eval): If necessary, update default_target_name when
2526 reading rules.
2527 * read.c (record_files): Update default_target_file if
2528 default_target_name has changed.
2529 * main.c (default_target_name): Define.
2530 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2531 default_target_name is set use default_target_file as a root
2532 target to make.
2533 * filedef.h (default_target_name): Declare.
2534 * dep.h (free_dep_chain):
2535 * misc.c (free_dep_chain): Change to operate on struct nameseq
2536 and change name to free_ns_chain.
2537 * file.c (snap_deps): Update to use free_ns_chain.
2539 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2541 Implementation of the second expansion in explicit rules,
2542 static pattern rules and implicit rules.
2544 * read.c (eval): Refrain from chopping up rule's dependencies.
2545 Store them in a struct dep as a single dependency line. Remove
2546 the code that implements SySV-style automatic variables.
2548 * read.c (record_files): Adjust the code that handles static
2549 pattern rules to expand all percents instead of only the first
2550 one. Reverse the order in which dependencies are stored so that
2551 when the second expansion reverses them again they appear in
2552 the makefile order (with some exceptions, see comments in
2553 the code). Remove the code that implements SySV-style automatic
2554 variables.
2556 * file.c (snap_deps): Implement the second expansion and chopping
2557 of dependency lines for explicit rules.
2559 * implicit.c (struct idep): Define an auxiliary data type to hold
2560 implicit rule's dependencies after stem substitution and
2561 expansion.
2563 * implicit.c (free_idep_chain): Implement.
2565 * implicit.c (get_next_word): Implement helper function for
2566 parsing implicit rule's dependency lines into words taking
2567 into account variable expansion requests. Used in the stem
2568 splitting code.
2570 * implicit.c (pattern_search): Implement the second expansion
2571 for implicit rules. Also fixes bug #12091.
2573 * commands.h (set_file_variables): Declare.
2574 * commands.c (set_file_variables): Remove static specifier.
2576 * dep.h (free_dep_chain): Declare.
2577 * misc.c (free_dep_chain): Implement.
2579 * variable.h (variable_expand_for_file): Declare.
2580 * expand.c (variable_expand_for_file): Remove static specifier.
2582 * make.h (strip_whitespace): Declare.
2583 * function.c (strip_whitespace): Remove static specifier.
2585 2005-02-26 Paul D. Smith <psmith@gnu.org>
2587 * main.c (main): Check for ferror() when reading makefiles from stdin.
2588 Apparently some shells in Windows don't close pipes properly and
2589 require this check.
2591 2005-02-24 Jonathan Grant <jg@jguk.org>
2593 * configure.in: Add MinGW configuration options, and extra w32 code
2594 directory.
2595 * Makefile.am: Add MinGW configuration options, and extra w32 code
2596 directory.
2597 * main.c: Determine correct program string (after last \ without .exe).
2598 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2599 type fix x2
2600 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2601 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2602 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2603 environment support.
2605 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2607 * function.c (func_shell): When initializing error_prefix, check
2608 that reading file name is not null. This fixes long-standing
2609 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2611 2005-02-09 Paul D. Smith <psmith@gnu.org>
2613 * maintMakefile: Update the CVS download URL to simplify them.
2614 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2615 downloading the .texi files from Savannah now.
2617 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2619 * main.c (handle_non_switch_argument): Only add variables to
2620 command_variables if they're not already there: duplicate settings
2621 waste space and can be confusing to read.
2623 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2624 this header is never included by non-WINDOWS32 code, and it
2625 requires <config.h> to define which isn't always included first.
2627 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2628 testing MINGW32 versions.
2630 * main.c (log_working_directory): flush stdout to be sure the WD
2631 change is printed before any stderr messages show up.
2633 2005-02-01 Paul D. Smith <psmith@gnu.org>
2635 * maintMakefile (po_repo): Update the GNU translation site URL.
2637 2004-12-01 Paul D. Smith <psmith@gnu.org>
2639 * main.c (main): Change char* env_shell to struct variable shell_var.
2640 * variable.c (target_environment): Use new shell_var.
2642 2004-11-30 Paul D. Smith <psmith@gnu.org>
2644 * configure.in: The old way we avoided creating build.sh from
2645 build.sh.in before build.sh.in exists doesn't work anymore; we
2646 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2647 the help!). This also keeps automake from complaining.
2648 * Makefile.am (README): Add a dummy target so automake won't
2649 complain that this file doesn't exist when we checkout from CVS.
2650 * maintMakefile (.dep_segment): Rewrite this rule since newer
2651 versions of automake don't provide DEP_FILES.
2653 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2655 Implementation of `realpath' and `abspath' built-in functions.
2657 * configure.in: Check for realpath.
2658 * function.c (abspath): Return an absolute file name that does
2659 not contain any `.' or `..' components, nor repeated `/'.
2660 * function.c (func_abspath): For each name call abspath.
2661 * function.c (func_realpath): For each name call realpath
2662 from libc or delegate to abspath if realpath is not available.
2663 * doc/make.texi (Functions for File Names): Document new functions.
2664 * doc/make.texi (Quick Reference): Ditto.
2666 2004-11-28 Paul D. Smith <psmith@gnu.org>
2668 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2669 arguments. Fixes bug #10252.
2671 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2673 * main.c (main): Set SHELL to v_noexport by default. Remember the
2674 original environment setting of SHELL in the env_shell variable.
2675 * main.h: Export new env_shell variable.
2676 * variable.c (target_environment): If we find a v_noexport
2677 variable for SHELL, add a SHELL variable with the env_shell value.
2678 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2679 * doc/make.texi (Variables/Recursion): Ditto.
2681 2004-11-28 Paul D. Smith <psmith@gnu.org>
2683 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2684 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2685 Patch by Alessandro Vesely.
2687 2004-11-12 Paul D. Smith <psmith@gnu.org>
2689 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2690 the command line if it's inside a string.
2691 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2693 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2695 * function.c (func_lastword): New function: return last word
2696 from the list of words.
2697 * doc/make.texi: Document $(lastword ). Fix broken links in
2698 Quick Reference section.
2700 2004-10-06 Paul D. Smith <psmith@gnu.org>
2702 Apply patch from Alessandro Vesely, provided with bug # 9748.
2703 Fix use of tmpnam() to work with Borland C.
2705 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2706 construction of a temporary filename, and call new function
2707 create_batch_filename().
2708 (create_batch_filename) [WINDOWS32]: New function to create a
2709 temporary filename.
2711 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2713 * read.c (record_target_var): Expand simple pattern-specific
2714 variable.
2715 * variable.c (initialize_file_variables): Do not expand simple
2716 pattern-specific variable.
2718 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2720 * remake.c (update_file_1): When rebuilding makefiles inherit
2721 dontcare flag from a target that triggered update.
2723 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2725 * variable.c (initialize_file_variables): Mark pattern-specific
2726 variable as a per-target and copy export status.
2728 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2730 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2732 * implicit.c (pattern_search): When considering an implicit rule's
2733 prerequisite check that it is actually a target rather then
2734 just an entry in the file hashtable.
2736 2004-09-21 Paul D. Smith <psmith@gnu.org>
2738 * read.c (readstring): Fix some logic errors in backslash handling.
2739 (eval): Remove some unnecessary processing in buffer handling.
2740 (record_target_var): Assert that parse_variable_definition() succeeded.
2741 Reported by: Markus Mauhart <qwe123@chello.at>.
2743 * misc.c: Removed the sindex() function. All instances of this
2744 function were trivially replaceable by the standard strstr()
2745 function, and that function will always have better (or certainly
2746 no worse) performance than the very simple-minded algorithm
2747 sindex() used. This can matter with complex makefiles.
2748 * make.h: Remove the prototype for sindex().
2749 * function.c (subst_expand): Convert sindex() call to strstr().
2750 This means we no longer need to track the TLEN value so remove that.
2751 (func_findstring): Convert sindex() to strstr().
2752 * commands.c (chop_commands): Convert sindex() calls to strstr().
2753 Suggested by: Markus Mauhart <qwe123@chello.at>.
2755 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2756 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2757 If SHELL is set to CMD.EXE then assume it's batch-mode and
2758 non-unixy. I wrote the code differently from the patch, though,
2759 to make it safer. This also resolves bug #9174.
2761 2004-09-20 Paul D. Smith <psmith@gnu.org>
2763 * expand.c (variable_expand_string): Modify to invoke
2764 patsubst_expand() instead of subst_expand(); the latter didn't
2765 handle suffix patterns correctly.
2766 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2767 was used only from variable_expand_string() and is no longer used
2768 there.
2769 (func_subst): Ditto, on call to subst_expand().
2770 (patsubst_expand): Require the percent pointers to point to the
2771 character after the %, not to the % itself.
2772 * read.c (record_files): New call criteria for patsubst_expand().
2773 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2774 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2776 2004-09-19 Paul D. Smith <psmith@gnu.org>
2778 * function.c (subst_expand): Fix a check in by_word: look for a
2779 previous blank if we're beyond the beginning of the string, not
2780 the beginning of the word.
2781 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2783 2004-05-16 Paul D. Smith <psmith@gnu.org>
2785 * remake.c (update_goal_chain): Change the argument specifying
2786 whether we're rebuilding makefiles to be a global variable,
2787 REBUILDING_MAKEFILES.
2788 (complain): Extract the code that complains about no rules to make
2789 a target into a separate function.
2790 (update_file_1): If we tried to rebuild a file during the makefile
2791 rebuild phase and it was dontcare, then no message was printed.
2792 If we then try to build the same file during the normal build,
2793 print a message this time.
2794 (remake_file): Don't complain about un-remake-able files when
2795 we're rebuilding makefiles.
2797 2004-05-11 Paul D. Smith <psmith@gnu.org>
2799 * job.c (construct_command_argv_internal): OS/2 patches from
2800 Andreas Buening <andreas.buening@nexgo.de>.
2802 2004-05-10 Paul D. Smith <psmith@gnu.org>
2804 * remake.c (update_file): Don't walk the double-colon chain unless
2805 this is a double-colon rule. Fix suggested by Boris Kolpackov
2806 <boris@kolpackov.net>.
2808 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2809 * readme.vms: New section describing OpenVMS support and issues.
2810 * default.c (default_variables): Add support for IA64.
2811 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2812 without some privilege aborts make with the error
2813 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2814 pressing Ctrl+Y and the input device is no terminal. The change
2815 catches this error and just continues.
2817 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2819 2004-04-25 Paul D. Smith <psmith@gnu.org>
2821 * commands.c (set_file_variables): Set $< properly in the face of
2822 order-only prerequisites.
2823 Patch from Boris Kolpackov <boris@kolpackov.net>
2825 2004-04-21 Bob Byrnes <byrnes@curl.com>
2827 * main.c (main): Notice failures to remake makefiles.
2829 2004-03-28 Paul D. Smith <psmith@gnu.org>
2831 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2833 * job.c: No default shell for RISC OS.
2834 (load_too_high): Hard-code the return to 1.
2835 (construct_command_argv_internal): No sh_chars or sh_cmds.
2836 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2838 2004-03-20 Paul D. Smith <psmith@gnu.org>
2840 * variable.c (do_variable_definition): Don't append from the
2841 global set if a previous non-appending target-specific variable
2842 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2843 (with fix).
2845 * expand.c (reference_variable): Don't give up on variables with
2846 no value that have the target-specific append flag set: they might
2847 have a value after all. Reported by Oliver Schmidt
2848 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2849 <nikulin@dx1cmd.inp.nsk.su>.
2851 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2852 refer to absolute pathnames in directories that don't exist: some
2853 portion of the makefile could create those directories before we
2854 match the pattern. Fixes bugs #775 and #108.
2856 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2858 * main.c (main): Free makefile_mtimes if we have any.
2859 * README.W32.template: Update documentation for the current status
2860 of the MS-Windows port.
2861 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2862 environment variable is sometimes already defined which causes the
2863 build to fail.
2864 * main.c (debug_signal_handler): Only define this function if
2865 SIGUSR1 is available.
2867 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2869 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2870 * README.OS2.template: Documentation updates.
2871 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2872 link line for safety.
2873 * maintMakefile (build.sh.in): Remove an extraneous ")".
2874 * job.c (child_execute_job): Close saved FDs.
2875 * job.c (exec_command) [OS/2]: exec_command(): If the command
2876 can't be exec'ed and if the shell is not Unix-sh, then try again
2877 with argv = { "cmd", "/c", ... }. Normally, this code is never
2878 reached for the cmd shell unless the command really doesn't exist.
2879 (construct_command_argv_internal) [OS/2]: The code for cmd
2880 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2881 The CMD builtin commands are case insensitive so use strcasecmp().
2883 2004-03-19 Paul D. Smith <psmith@gnu.org>
2885 * read.c (do_define): Re-order line counter increment so the count
2886 is accurate (we were losing one line per define). Reported by
2887 Dave Yost <Dave@Yost.com>.
2889 2004-03-06 Paul D. Smith <psmith@gnu.org>
2891 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2892 compiler.
2893 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2894 * misc.c (message,error,fatal): Ditto.
2895 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2896 * config.h.W32.template: Ditto.
2897 * config.h-vms.template: Ditto.
2898 * config.ami.template: Ditto.
2900 2004-03-04 Paul D. Smith <psmith@gnu.org>
2902 * README.template: Add a note about broken /bin/sh on SunOS
2903 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2905 * misc.c (message, error, fatal): Don't use "..." if we're using
2906 varargs. ansi2knr should handle this but it doesn't work: it
2907 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2908 done. On many systems (SunOS for example) va_dcl is a #define.
2909 So, force the use of the non-"..." version on pre-ANSI compilers.
2911 * maintMakefile (sign-dist): Create some rules to help automate
2912 the new GNU ftp upload method.
2914 2004-02-24 Paul D. Smith <psmith@gnu.org>
2916 * config.h.W32.template: Add HAVE_STDARG_H
2917 * config.h-vms.template: Ditto.
2918 * config.ami.template: Ditto.
2920 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2922 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2923 * build_w32.bat: Remove extra "+".
2925 2004-02-23 Paul D. Smith <psmith@gnu.org>
2927 * make.h: Create an UNUSED macro to mark unused parameters.
2928 * (many): Clean up warnings by applying UNUSED, fixing
2929 signed/unsigned incompatibilities, etc.
2931 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2932 autoconf warnings.
2933 * filedef.h: Name the command_state enumeration.
2934 * file.c (set_command_state): Use the enumeration in the function
2935 argument.
2937 * configure.in: Explicitly set SET_MAKE to empty, to disable
2938 MAKE=make even when no make already exists. Fix bug #3823.
2940 2004-02-22 Paul D. Smith <psmith@gnu.org>
2942 * maintMakefile: Perl script to clean up all non-CVS files. Use
2943 it on all the subdirectories for the cvs-clean target.
2945 * main.c (decode_switches): Require non-empty strings for all our
2946 string command-line options. Fixes Debian bug # 164165.
2948 * configure.in: Check for stdarg.h and varargs.h.
2949 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2950 for printing messages.
2951 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2952 (message): Ditto.
2953 (error): Ditto.
2954 (fatal): Ditto.
2956 A number of patches for OS/2 support from Andreas Buening
2957 <andreas.buening@nexgo.de>:
2959 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2960 disable the SIGCHLD handler.
2961 (reap_children) [OS/2]: Remove special handling of job_rfd.
2962 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2963 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2964 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2965 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2966 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2967 systems.
2969 2004-02-21 Paul D. Smith <psmith@gnu.org>
2971 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2972 <mail@kristov.de> reports that if process_begin() fails we don't
2973 handle the error condition correctly in all cases.
2974 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2975 to have a newline on the message.
2977 * job.c (construct_command_argv_internal): Add "test" to UNIX
2978 sh_cmds[]. Fixes Savannah bug # 7606.
2980 2004-02-04 Paul D. Smith <psmith@gnu.org>
2982 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2983 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2984 Hartmut Becker <Hartmut.Becker@hp.com>.
2986 2004-01-21 Paul D. Smith <psmith@gnu.org>
2988 * job.c (load_too_high): Implement an algorithm to control the
2989 "thundering herd" problem when using -l to control job creation
2990 via the load average. The system only recomputes the load once a
2991 second but we can start many jobs in a second. To solve this we
2992 keep track of the number of jobs started in the last second and
2993 apply a weight to try to guess what a correct load would be.
2994 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2995 Also fixes bug #4693.
2996 (reap_children): Decrease the job count for this second.
2997 (start_job_command): Increase the job count for this second.
2999 * read.c (conditional_line): Expand the text after ifn?def before
3000 checking to see if it's a single word. Fixes bug #7257.
3002 2004-01-09 Paul D. Smith <psmith@gnu.org>
3004 * file.c (print_file): Recurse to print all targets in
3005 double-colon rules. Fixes bug #4518, reported (with patch) by
3006 Andrew Chatham <chatham@google.com>.
3008 2004-01-07 Paul D. Smith <psmith@gnu.org>
3010 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3011 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3012 AC_FUNC_SETVBUF_REVERSED.
3014 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3015 (MAKE Variable): Fix Savannah bug #4898.
3017 * job.c (construct_command_argv_internal): Add "!" to the list of
3018 shell escape chars. POSIX sh allows it to appear before a
3019 command, to negate the exit code. Fixes bug #6404.
3021 * implicit.c (pattern_search): When matching an implicit rule,
3022 remember which dependencies have the ignore_mtime flag set.
3023 Original fix provided in Savannah patch #2349, by Benoit
3024 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3026 2003-11-22 Paul D. Smith <psmith@gnu.org>
3028 * README.W32.template (Outputs): Clarification on -j with
3029 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3030 <jg-make@jguk.org>.
3032 2003-11-02 Paul D. Smith <psmith@gnu.org>
3034 * function.c (func_if): Strip all the trailing whitespace from the
3035 condition, then don't expand it. Fixed bug # 5798.
3037 * expand.c (recursively_expand_for_file): If we're expanding a
3038 variable with no file context, then use the variable's context.
3039 Fixes bug # 6195.
3041 2003-10-21 Paul D. Smith <psmith@gnu.org>
3043 * main.c (log_working_directory): Add newlines to printf()s.
3045 * README.cvs: Add a note to ignore warnings during autoreconf.
3047 * maintMakefile (po_repo): Set a new URL for PO file updates.
3048 (get-config/config.guess get-config/config.sub): Get these files
3049 from the Savannah config project instead of ftp.gnu.org.
3051 2003-10-05 Paul Eggert <eggert@twinsun.com>
3053 * main.c (main): Avoid potential subscript error if environ has
3054 short strings.
3056 2003-08-22 Paul D. Smith <psmith@gnu.org>
3058 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3059 systems which don't yet implement the C89 standard :-/.
3061 2003-07-18 Paul D. Smith <psmith@gnu.org>
3063 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3064 [WINDOWS32]: Initialize hash.
3066 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3068 * dir.c (read_dirstream): Provide a workaround for broken versions of
3069 the MinGW dirent structure.
3071 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3073 * w32/include/dirent.h: Add __MINGW32__ filter.
3075 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3077 * make.h: Add global declaration of *make_host.
3078 * main.c (print_usage): Remove local declaration of *make_host.
3079 (print_version): Display "This program built for ..." after Copyright
3080 notice.
3082 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3084 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3085 execution of "makeinfo --html make.texi".
3087 2003-04-30 Paul D. Smith <psmith@gnu.org>
3089 * build.template: Make some changes to maybe allow this script to
3090 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3092 * README.OS2.template: New file for OS/2 support. Original
3093 contributed by Andreas Buening.
3094 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3095 DOS-style paths.
3097 2003-04-19 Paul D. Smith <psmith@gnu.org>
3099 Fix bug #1405: allow a target to match multiple pattern-specific
3100 variables.
3102 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3103 variable.c, where they've always belonged.
3104 * rule.h: Move the prototypes and struct pattern_var as well.
3105 * variable.c (initialize_file_variables): Invoke
3106 lookup_pattern_var() in a loop, until no more matches are found.
3107 If a match is found, create a new variable set for the target's
3108 pattern variables. Then merge the contents of each matching
3109 pattern variable set into the target's pattern variable set.
3110 (lookup_pattern_var): Change this function to be usable
3111 in a loop. It takes a starting position: if NULL, start at the
3112 beginning; if non-NULL, start with the pattern variable after that
3113 position, and return the next matching pattern.
3114 (create_pattern_var): Create a unique instance of
3115 pattern-specific variables for every definition in the makefile.
3116 Don't combine the same pattern together. This allows us to
3117 process the variable handling properly even when the same pattern
3118 is used multiple times.
3119 (parse_variable_definition): New function: break out the parsing
3120 of a variable definition line from try_variable_definition.
3121 (try_variable_definition): Call parse_variable_definition to
3122 parse.
3123 (print_variable_data_base): Print out pattern-specific variables.
3124 * variable.h (struct variable): Remember when a variable is
3125 conditional. Also remember its flavor.
3126 (struct pattern_var): Instead of keeping a variable set, we just
3127 keep a single variable for each pattern.
3128 * read.c (record_target_var): Each pattern variable contains only a
3129 single variable, not a set, so create it properly.
3130 * doc/make.texi (Pattern-specific): Document the new behavior.
3132 2003-04-17 Paul D. Smith <psmith@gnu.org>
3134 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3135 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3136 file/directory naming rules for VMS so I can't tell whether this
3137 is correct or not.
3139 2003-04-09 Paul D. Smith <psmith@gnu.org>
3141 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3142 DOS-style pathnames: backslash separators and drive specifiers.
3144 2003-03-28 Paul D. Smith <psmith@gnu.org>
3146 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3147 the intermediate flag on all targets. Fixes bug #2515.
3149 2003-03-24 Paul D. Smith <psmith@gnu.org>
3151 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3152 Upgrade to autoconf 2.57 and automake 1.7.3.
3154 * job.c: More OS/2 changes from Andreas Buening.
3156 * file.c (print_file): Fix variable initialization.
3157 Fixes bug #2892.
3159 * remake.c (notice_finished_file):
3161 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3162 some calls (like readdir()) return NULL in valid situations
3163 without resetting errno. Fixes bug #2846.
3165 2003-02-25 Paul D. Smith <psmith@gnu.org>
3167 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3169 * job.c (_is_unixy_shell) [OS/2]: New function.
3170 Set default shell to /bin/sh.
3171 (reap_children): Close the job_rfd pipe here since we don't use a
3172 SIGCHLD handler.
3173 (set_child_handler_action_flags): define this to empty on OS/2.
3174 (start_job_command): Close the jobserver pipe and use
3175 child_execute_job() instead of fork/exec.
3176 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3177 rather than exec'ing, then reconfigure stdin/stdout.
3178 (exec_command): Rewrite to use spawn instead of exec. Return the
3179 PID of the child.
3181 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3182 in DOS. Handle the TEMP environment variable as in DOS. Don't
3183 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3184 use -j in DOS mode. Use child_execute_job() instead of
3185 exec_command().
3187 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3188 spawn() instead.
3190 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3191 prototypes that return values.
3193 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3195 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3196 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3197 for OS/2.
3198 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3199 DOS paths.
3201 2003-02-24 Paul D. Smith <psmith@gnu.org>
3203 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3204 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3205 (child_execute_job) [VMS]: Handle error status properly.
3206 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3208 * function.c (func_shell): Use EINTRLOOP() while reading from the
3209 subshell pipe (Fixes bug #2502).
3210 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3211 jobserver pipe.
3212 * main.c (main): Ditto.
3214 2003-01-30 Paul D. Smith <psmith@gnu.org>
3216 * read.c (eval): eval() was not fully reentrant, because the
3217 collapsed buffer was static. Change it to be an automatic
3218 variable so that eval() can be invoked recursively.
3219 Fixes bug # 2238.
3220 (eval): Apply patch # 1022: fix memory reference error on long
3221 target-specific variable lines.
3222 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3224 * function.c (check_numeric): Combine the is_numeric() function
3225 into this function, since it's only called from one place.
3226 Constify this function. Have it print the incorrect string in the
3227 error message. Fixes bug #2407.
3228 (strip_whitespace): Constify.
3229 (func_if): Constify.
3230 * expand.c (expand_argument): Constify.
3232 2003-01-29 Paul D. Smith <psmith@gnu.org>
3234 Fix bug # 2169, also reported by other people on various systems.
3236 * make.h: Some systems, such as Solaris and PTX, do not fully
3237 implement POSIX-compliant SA_RESTART functionality; important
3238 system calls like stat() and readdir() can still fail with EINTR
3239 even if SA_RESTART has been set on the signal handler. So,
3240 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3241 EINTR for system calls which return -1 or 0 (NULL), respectively,
3242 on error.
3243 Also, remove the old atomic_stat()/atomic_readdir() and
3244 HAVE_BROKEN_RESTART handling.
3246 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3248 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3249 * remake.c (touch_file): Ditto.
3251 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3252 * read.c (construct_include_path): Ditto.
3253 * remake.c (name_mtime): Ditto.
3254 * vpath.c (selective_vpath_search): Ditto.
3255 * dir.c (find_directory): Ditto.
3256 (local_stat): Ditto.
3257 (find_directory): Use ENULLLOOP() to wrap opendir().
3258 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3260 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3261 atomic_readdir() handling.
3263 2003-01-22 Paul D. Smith <psmith@gnu.org>
3265 * function.c (func_call): Fix Bug #1744. If we're inside a
3266 recursive invocation of $(call ...), mask any of the outer
3267 invocation's arguments that aren't used by this one, so that this
3268 invocation doesn't "inherit" them accidentally.
3270 2002-12-05 Paul D. Smith <psmith@gnu.org>
3272 * function.c (subst_expand): Valery Khamenia reported a
3273 pathological performance hit when doing substitutions on very
3274 large values with lots of words: turns out we were invoking
3275 strlen() a ridiculous number of times. Instead of having each
3276 call to sindex() call strlen() again, keep track of how much of
3277 the text we've seen and pass the length to sindex().
3279 2002-11-19 Paul D. Smith <psmith@gnu.org>
3281 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3284 2002-11-16 Paul D. Smith <psmith@gnu.org>
3286 * NMakefile.template (OBJS): Add hash.c object file.
3287 * SMakefile.template (srcs): Ditto.
3288 * Makefile.ami (objs): Ditto.
3289 * build_w32.bat: Ditto.
3291 * Makefile.DOS.template: Remove extra dependencies.
3293 2002-10-25 Paul D. Smith <psmith@gnu.org>
3295 * expand.c (install_variable_buffer): New function. Install a new
3296 variable_buffer context and return the previous one.
3297 (restore_variable_buffer): New function. Free the current
3298 variable_buffer context and put a previously saved one back.
3299 * variable.h: Prototypes for {install,restore}_variable_buffer.
3300 * function.c (func_eval): Push a new variable_buffer context
3301 before we eval, then restore the old one when we're done.
3302 Fixes Bug #1517.
3304 * read.c (install_conditionals): New function. Install a new
3305 conditional context and return the previous one.
3306 (restore_conditionals): New function. Free the current
3307 conditional context and put a previously saved one back.
3308 (eval): Use the {install,restore}_conditionals for "include"
3309 handling.
3310 (eval_buffer): Use {install,restore}_conditionals to preserve the
3311 present conditional state before we evaluate the buffer.
3312 Fixes Bug #1516.
3314 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3315 and $(value ...).
3316 (Recursion): Add a variable index entry for CURDIR.
3318 * README.cvs: Update to appropriate versions.
3319 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3320 don't need to copy loadavg.c: automake is smart enough to create
3321 it for me. Still have a bug in automake related to ansi2knr tho.
3323 2002-10-14 Paul D. Smith <psmith@gnu.org>
3325 * remake.c (notice_finished_file): Only touch targets if they have
3326 at least one command (as per POSIX). Resolve Bug #1418.
3328 * *.c: Convert to using ANSI C-style function definitions.
3329 * Makefile.am: Enable the ansi2knr feature of automake.
3330 * configure.in: ditto.
3332 2002-10-13 Paul D. Smith <psmith@gnu.org>
3334 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3335 for automatic variable values like $^, etc. In the case of very
3336 large lists of prerequisites this causes problems. Instead reuse
3337 a static buffer (resizeable) for each variable.
3339 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3340 target-specific variable definitions. Check for it and set an
3341 "exported" flag.
3342 (record_target_var): Set the export field to v_export if the
3343 "exported" flag is set.
3344 * doc/make.texi (Target-specific): Document the ability to use
3345 "export".
3347 * doc/make.texi: Change the name of the section on automatic
3348 variables from "Automatic" to "Automatic Variables". Added text
3349 clarifying the scope of automatic variables.
3351 2002-10-04 Paul D. Smith <psmith@gnu.org>
3353 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3354 as () braces.
3355 (record_files): Ditto.
3357 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3358 the search for the '=' to only within the enclosing parens.
3360 2002-10-03 Paul D. Smith <psmith@gnu.org>
3362 Version 3.80 released.
3364 * dir.c: Change hash functions to use K&R function definition style.
3365 * function.c: Ditto.
3366 * read.c: Ditto.
3367 * variable.c: Ditto.
3369 Update to automake 1.7.
3371 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3372 (pdf): Remove this target as automake now provides one.
3374 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3376 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3378 * makefile.com: Updates for GNU make 3.80.
3379 * makefile.vms: Ditto.
3381 2002-09-23 Paul D. Smith <psmith@gnu.org>
3383 * read.c (enum make_word_type): Remove w_comment.
3384 (get_next_mword): Don't treat comment characters as special; where
3385 this function is used we will never see a comment (it's stripped
3386 before we get here) and treating comments specially means that
3387 targets like "foo\#bar" aren't handled properly.
3389 2002-09-18 Paul D. Smith <psmith@gnu.org>
3391 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3393 * read.c (eval): Expansion of arguments to export/unexport was
3394 ignoring all arguments after the first one. Change the algorithm
3395 to expand the whole line once, then parse the results.
3397 2002-09-17 Paul D. Smith <psmith@gnu.org>
3399 Fix Bug #940 (plus another bug I found while looking at this):
3401 * read.c (record_target_var): enter_file() will add a new entry if
3402 it's a double-colon target: we don't want to do that in this
3403 situation. Invoke lookup_file() and only enter_file() if it does
3404 not already exist. If the file we get back is a double-colon then
3405 add this variable to the "root" double-colon target.
3407 * variable.c (initialize_file_variables): If this file is a
3408 double-colon target but is not the "root" target, then initialize
3409 the root and make the root's variable list the parent of our
3410 variable list.
3412 2002-09-13 Paul D. Smith <psmith@gnu.org>
3414 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3416 * hash.c (round_up_2): Get rid of a warning.
3418 2002-09-12 Paul D. Smith <psmith@gnu.org>
3420 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3421 so it doesn't complain about getloadavg.c.
3423 * commands.c (set_file_variables): Make sure we always alloca() at
3424 least 1 character for the value of $? (for '\0').
3426 2002-09-11 Paul D. Smith <psmith@gnu.org>
3428 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3429 macro to use RESULT instead of the incorrect _RESULT_.
3431 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3432 and atomic_readdir(). We need to #include dirent.h to get this to
3433 work.
3434 * misc.c (atomic_readdir): Fix typos.
3436 2002-09-10 Paul D. Smith <psmith@gnu.org>
3438 * read.c (eval): Expand variable lists given to export and
3439 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3440 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3442 * doc/make.texi (Variables/Recursion): Document this.
3443 (Conditional Syntax): And here.
3445 2002-09-09 Paul D. Smith <psmith@gnu.org>
3447 * configure.in: Check for memmove().
3449 2002-09-07 Paul D. Smith <psmith@gnu.org>
3451 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3452 Michael Sterrett <msterret@coat.com> reports that while it has
3453 SA_RESTART, it does not work properly.
3455 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3456 that invokes stat() and loops to do it again if it returns EINTR.
3457 (atomic_readdir): Ditto, with readdir().
3459 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3460 and readdir() to atomic_stat() and atomic_readdir().
3462 2002-09-04 Paul D. Smith <psmith@gnu.org>
3464 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3465 reports that GNU make sometimes doesn't recognize that targets can
3466 be made, when directories can be created as prerequisites. He
3467 reports that changing the order of predicates in the DEP->changed
3468 flag test so that lookup_file() is always performed, solves this
3469 problem.
3471 2002-08-08 Paul D. Smith <psmith@gnu.org>
3473 * configure.in: Require a newer version of gettext.
3475 * misc.c (perror_with_name): Translate the format string (for
3476 right-to-left language support).
3477 (pfatal_with_name): Ditto.
3479 * main.c: Create a static array of strings to store the usage
3480 text. This is done to facilitate translations.
3481 (struct command_switch): Remove argdesc and description fields.
3482 (switches): Remove values for obsolete fields.
3483 (print_usage): Print each element of the usage array.
3485 * hash.c: Change function definitions to be K&R style.
3487 2002-08-02 Paul D. Smith <psmith@gnu.org>
3489 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3490 this one because it's too hard to get right. We'll look at it for
3491 a future release.
3492 * main.c (main): Don't create the .TARGETS variable.
3493 * variable.c (handle_special_var): Don't handle .TARGETS.
3495 2002-08-01 Paul D. Smith <psmith@gnu.org>
3497 * main.c (switches): Add a new option, -B (--always-make). If
3498 specified, make will rebuild all targets that it encounters even
3499 if they don't appear to be out of date.
3500 (always_make_flag): New flag.
3501 * make.h: Extern always_make_flag.
3502 * remake.c (update_file_1): Check always_make_flag; if it's set we
3503 will always rebuild any target we can, even if none of its
3504 prerequisites are newer.
3505 * NEWS: Mention it.
3507 * doc/make.texi (Shell Function): Make it clear that make
3508 variables marked as "export" are not passed to instances of the
3509 shell function.
3511 Add new introspection variable .VARIABLES and .TARGETS.
3513 * variable.c (handle_special_var): New function. If the variable
3514 reference passed in is "special" (.VARIABLES or .TARGETS),
3515 calculate the new value if necessary. .VARIABLES is handled here:
3516 walk through the hash of defined variables and construct a value
3517 which is a list of the names. .TARGETS is handled by
3518 build_target_list().
3519 (lookup_variable): Invoke handle_special_var().
3520 * file.c (build_target_list): Walk through the hask of known files
3521 and construct a list of the names of all the ones marked as
3522 targets.
3523 * main.c (main): Initialize them to empty (and as simple variables).
3524 * doc/make.texi (Special Variables): Document them.
3525 * NEWS: Mention them.
3527 * variable.h (struct variable): Add a new flag "exportable" which
3528 is true if the variable name is valid for export.
3529 * variable.c (define_variable_in_set): Set "exportable" when a new
3530 variable is defined.
3531 (target_environment): Use the "exportable" flag instead of
3532 re-checking the name here... an efficiency improvement.
3534 2002-07-31 Paul D. Smith <psmith@gnu.org>
3536 * config.h-vms.template: Updates to build on VMS. Thanks to
3537 Brian_Benning@aksteel.com for helping verify the build.
3538 * makefile.com: Build the new hash.c file.
3539 * hash.h: Use strcpmi(), not stricmp(), in the
3540 HAVE_CASE_INSENSITIVE_FS case.
3542 2002-07-30 Paul D. Smith <psmith@gnu.org>
3544 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3545 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3546 Reported by <Brian_Benning@aksteel.com>.
3548 2002-07-10 Paul D. Smith <psmith@gnu.org>
3550 * variable.c (pop_variable_scope): Remove variable made unused by
3551 new hash infrastructure.
3552 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3553 comparisons as well as name comparisons.
3554 * variable.h: Add a prototype for new hash_init_function_table().
3555 * file.c (lookup_file): Remove variables made unused by new hash
3556 infrastructure.
3557 * dir.c (directory_contents_hash_2): Missing return of hash value.
3558 (dir_contents_file_exists_p): Remove variables made unused by new
3559 hash infrastructure.
3562 Installed Greg McGary's integration of the hash functions from the
3563 GNU id-utils package:
3565 2002-07-10 Greg McGary <greg@mcgary.org>
3567 * scripts/functions/filter-out: Add literals to to the
3568 pattern space in order to add complexity, and trigger
3569 use of an internal hash table. Fix documentation strings.
3570 * scripts/targets/INTERMEDIATE: Reverse order of files
3571 passed to expected `rm' command.
3573 2002-07-10 Greg McGary <greg@mcgary.org>
3575 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

3628 (lookup_function): Remove `table' argument.
3629 Use new hash table package.
3630 (struct a_word) [chain, length]: New members.
3631 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3632 (struct a_pattern): New struct.
3633 (func_filter_filterout): Pass through patterns noting boundaries
3634 and '%', if present. Note a_word length. Use a hash table if
3635 arglists are large enough to justify cost.
3636 (function_table_init): Renamed from function_table.
3637 (function_table): Declare as `struct hash_table'.
3638 (FUNCTION_TABLE_ENTRIES): New constant.

3646 than a string constant, avoiding zillions of calls to strchr.
3647 Tighten inner search loops to test only for desired delimiters.

3665 2002-07-10 Paul D. Smith <psmith@gnu.org>
3667 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3668 prerequisite list. A real SysV make will expand the entire
3669 prerequisites list _twice_: we don't do that as it's a big
3670 backward-compatibility problem. We only replace those specific
3671 variables.
3673 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3674 references left in the list of prerequisites. Check for .POSIX as
3675 we record targets, so we can disable non-POSIX behavior while
3676 reading makefiles as well as running them.
3677 (eval): Check the prerequisite list to see if we have anything
3678 that looks like a SysV prerequisite variable reference.
3680 2002-07-09 Paul D. Smith <psmith@gnu.org>
3682 * doc/make.texi (Prerequisite Types): Add a new section describing
3683 order-only prerequisites.
3685 * read.c (uniquize_deps): If we have the same file as both a
3686 normal and order-only prereq, get rid of the order-only prereq,
3687 since the normal one supersedes it.
3689 2002-07-08 Paul D. Smith <psmith@gnu.org>
3691 * AUTHORS: Added Greg McGary to the AUTHORS file.
3692 * NEWS: Blurbed order-only prerequisites.
3693 * file.c (print_file): Show order-only deps properly when printing
3694 the database.
3696 * maintMakefile: Add "update" targets for wget'ing the latest
3697 versions of various external files. Taken from Makefile.maint in
3698 autoconf, etc.
3700 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3701 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3703 2002-07-07 Paul D. Smith <psmith@gnu.org>
3705 * po/*.po: Remove. We'll use wget to retrieve them at release
3706 time.
3708 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3709 rather than a shell you get an exception. Make sure we look up
3710 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3712 * remake.c (notice_finished_file): Fix handling of -t flag.
3713 Patch provided by Henning Makholm <henning@makholm.net>.
3715 * implicit.c (pattern_search): Some systems apparently run short
3716 of stack space, and using alloca() in this function caused an
3717 overrun. I modified it to use xmalloc() on the two variables
3718 which seemed like they might get large. Fixes Bug #476.
3720 * main.c (print_version): Update copyright notice to conform with
3721 GNU standards.
3722 (print_usage): Update help output.
3724 * function.c (func_eval): Create a new make function, $(eval
3725 ...). Expand the arguments, put them into a buffer, then invoke
3726 eval_buffer() on the resulting string.
3727 (func_quote): Create a new function, $(quote VARNAME). Inserts
3728 the value of the variable VARNAME without expanding it any
3729 further.
3731 * read.c (struct ebuffer): Change the linebuffer structure to an
3732 "eval buffer", which can be either a file or a buffer.
3733 (eval_makefile): Move the code in the old read_makefile() which
3734 located a makefile into here: create a struct ebuffer with that
3735 information. Have it invoke the new function eval() with that
3736 ebuffer.
3737 (eval_buffer): Create a new function that creates a struct ebuffer
3738 that holds a string buffer instead of a file. Have it invoke
3739 eval() with that ebuffer.
3740 (eval): New function that contains the guts of the old
3741 read_makefile() function: this function parses makefiles. Obtains
3742 data to parse from the provided ebuffer. Some modifications to
3743 make the flow of the function cleaner and clearer. Still could
3744 use some work here...
3745 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3746 contents of the define/endef variable from the ebuffer.
3747 (readstring): Read the next line from a string-style ebuffer.
3748 (readline): Read the next line from an ebuffer. If it's a string
3749 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3750 from the file.
3752 * dep.h (eval_buffer): Prototype eval_buffer();
3754 * variable.c (do_variable_definition): Make sure that all
3755 non-target-specific variables are registered in the global set.
3756 If we're invoked from an $(eval ...) we might be inside a $(call
3757 ...) or other function which has pushed a variable scope; we still
3758 want to define our variables from evaluated makefile code in the
3759 global scope.
3761 2002-07-03 Greg McGary <greg@mcgary.org>
3763 * dep.h (struct dep) [ignore_mtime]: New member.
3764 [changed]: convert to a bitfield.
3765 * implicit.c (pattern_search): Zero ignore_mtime.
3766 * main.c (main, handle_non_switch_argument): Likewise.
3767 * rule.c (convert_suffix_rule): Likewise.
3768 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3769 (read_makefile): Parse '|' in prerequisite list.
3770 (uniquize_deps): Consider ignore_mtime when comparing deps.
3771 * remake.c (update_file_1, check_dep): Don't force remake for
3772 dependencies that have d->ignore_mtime.
3773 * commands.c (FILE_LIST_SEPARATOR): New constant.
3774 (set_file_variables): Don't include a
3775 prerequisite in $+, $^ or $? if d->ignore_mtime.
3776 Define $|.
3778 2002-06-18 Paul D. Smith <psmith@gnu.org>
3780 * make.texinfo: Updates for next revision. New date/rev/etc.
3781 Recreate all Info menus. Change license on the manual to the GNU
3782 Free Documentation License. A number of typos.
3783 (Variables Simplify): Don't use "-" before it's defined.
3784 (Automatic Prerequisites): Rewrite the target example to work
3785 properly if the compile fails. Remove incorrect comments about
3786 how "set -e" behaves.
3787 (Text Functions): Move the "word", "wordlist", "words", and
3788 "firstword" functions here, from "File Name Functions".
3789 * make-stds.texi: Update from latest GNU version.
3790 * fdl.texi: (created) Import the latest GNU version.
3792 2002-06-06 Paul D. Smith <psmith@gnu.org>
3794 * variable.c (do_variable_definition): New function: extract the
3795 part of try_variable_definition() that actually sets the value
3796 into a separate function.
3797 (try_variable_definition): Call do_variable_definition() after
3798 parsing the variable definition string.
3799 (define_variable_in_set): Make the name argument const.
3801 * variable.h (enum variable_flavor): Make public.
3802 (do_variable_definition): Create prototype.
3804 * read.c (read_all_makefiles): Create a new built-in variable,
3805 MAKEFILE_LIST.
3806 (read_makefile): Add each makefile read in to this variable value.
3808 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3810 * Makefile.DOS.template: Tweak according to changes in the
3811 distribution. Add back the dependencies of *.o files.
3813 * configh.dos.template: Synchronize with config.h.in.
3815 2002-05-09 Paul D. Smith <psmith@gnu.org>
3817 * file.c (file_timestamp_now): Use K&R function declaration.
3819 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3820 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3821 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3822 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3823 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3824 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3825 nlist.n_name is a pointer rather than an array.
3827 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3828 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3829 * configure.in: Use it instead of the old version.
3831 * main.c (main): Prefer setvbuf() to setlinebuf().
3833 2002-05-08 Paul D. Smith <psmith@gnu.org>
3835 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3836 (loadavg_LDADD): Ditto.
3838 2002-04-29 Paul D. Smith <psmith@gnu.org>
3840 * expand.c (recursively_expand_for_file): Rename
3841 recursively_expand() to recursively_expand_for_file() and provide
3842 an extra argument, struct file. If the argument is provided, set
3843 the variable scope to that of the file before expanding.
3844 * variable.h (recursively_expand): Make this a macro that invokes
3845 recursively_expand_for_file() with a NULL file pointer.
3846 * variable.c (target_environment): Call the renamed function and
3847 provide the current file context.
3848 Fixes Debian bug #144306.
3850 2002-04-28 Paul D. Smith <psmith@gnu.org>
3852 Allow $(call ...) user-defined variables to be self-referencing
3853 without throwing an error. Allows implementation of transitive
3854 closures, among other possibly useful things.
3855 Requested by: Philip Guenther <guenther@sendmail.com>
3857 * variable.h (struct variable): Add a new field: exp_count, and
3858 new macros to hold its size and maximum value.
3859 (warn_undefined): Make this a macro.
3860 * variable.c (define_variable_in_set): Initialize it.
3861 * expand.c (recursively_expand): If we detect recursive expansion
3862 of a variable, check the exp_count field. If it's greater than 0
3863 allow the recursion and decrement the count.
3864 (warn_undefined): Remove this (now a macro in variable.h).
3865 * function.c (func_call): Before we expand the user-defined
3866 function, modify its exp_count field to contain the maximum
3867 number of recursive calls we'll allow. After the call, reset it
3868 to 0.
3870 2002-04-21 Paul D. Smith <psmith@gnu.org>
3872 Modified to use latest autoconf (2.53), automake (1.6.1), and
3873 gettext (0.11.1). We're using gettext's new "external" support,
3874 to avoid including libintl source with GNU make.
3876 * README.cvs: New file. Explain how to build GNU make from CVS.
3878 * configure.in: Modify checking for the system glob library.
3879 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3880 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3881 etc. will manage it correctly). Set an automake conditional
3882 USE_LOCAL_GLOB to decide whether to compile the glob library.
3884 * getloadavg.c (main): Include make.h in the "TEST" program to
3885 avoid warnings.
3887 * Makefile.am: Remove special rules for loadavg. Replace them
3888 with Automake capabilities for building extra programs.
3890 * signame.c: This file does nothing if the system provide
3891 strsignal(). If not, it implements strsignal(). If the system
3892 doesn't define sys_siglist, then we make our own; otherwise we use
3893 the system version.
3894 * signame.h: Removed.
3896 * main.c (main): No need to invoke signame_init(). Update copyright.
3898 * ABOUT-NLS: Removed.
3899 * gettext.c: Removed.
3900 * gettext.h: Get a simplified copy from the gettext package.
3901 * po/*: Created.
3902 * i18n/*.po: Moved to po/.
3903 * i18n/: Removed.
3905 * config/*: Created. Contains package configuration helper files.
3906 * config.guess, config.sub: Moved to config directory.
3908 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3909 Rework to use new-style autoconf features. Use the "external"
3910 mode for gettext. Make the build.sh config file conditional on
3911 whether build.sh.in exists, to avoid autoconf errors.
3912 * acinclude.m4: Removed almost all macros as being obsolete.
3913 Rewrote remaining macros to use AC_DEFINE.
3914 * acconfig.h: Removed.
3916 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3917 conditional to handle customs support. Remove special handling
3918 for i18n features.
3920 2002-04-20 Paul D. Smith <psmith@gnu.org>
3922 * function.c (func_call): Don't mark the argument variables $1,
3923 etc. as recursive. They've already been fully expanded so
3924 there's no need to do it again, and doing so strips escaped $'s.
3925 Reported by Sebastian Glita <glseba@yahoo.com>.
3927 * remake.c (notice_finished_file): Walk through double-colon
3928 entries via the prev field, not the next field!
3929 Reported by Greg McGary <greg@mcgary.org>.
3931 * main.c (main): If the user specifies -q and asks for a specific
3932 target which is a makefile, we got an assert. In that case it
3933 turns out we should continue normally instead.
3935 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3937 * i18n/he.po: Installed a new translation.
3939 2002-01-07 Paul D. Smith <psmith@gnu.org>
3941 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3943 2001-12-04 Paul D. Smith <psmith@gnu.org>
3945 * i18n/ja.po: Installed an updated translation.
3947 2001-09-06 Paul Eggert <eggert@twinsun.com>
3949 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3950 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3952 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3953 are available.
3954 (main): Get rid of any avoidable limit on stack size.
3956 2001-09-04 Paul D. Smith <psmith@gnu.org>
3958 * i18n/da.po: Installed an updated translation.
3960 2001-08-03 Paul D. Smith <psmith@gnu.org>
3962 * i18n/fr.po: Installed an updated translation.
3963 Resolves Debian bug #106720.
3965 2001-06-13 Paul D. Smith <psmith@gnu.org>
3967 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3968 translation.
3970 2001-06-11 Paul D. Smith <psmith@gnu.org>
3972 * i18n/ko.po: Installed a new translation.
3974 2001-05-06 Paul D. Smith <psmith@gnu.org>
3976 Modify the EINTR handling.
3978 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3979 the way in which we manage the file descriptor/signal handler race
3980 trap to be more efficient.
3982 2001-05-06 Paul Eggert <eggert@twinsun.com>
3984 Restart almost all system calls that are interrupted, instead
3985 of worrying about EINTR. The lone exception is the read() for
3986 job tokens.
3988 * configure.in (HAVE_SA_RESTART): New macro.
3989 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3990 * main.c (main): Use SA_RESTART instead of the old,
3991 nonstandard SA_INTERRUPT.
3993 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3994 * main.c (bsd_signal): New function or macro,
3995 if the implementation doesn't supply it.
3996 (The bsd_signal function will be in POSIX 1003.1-200x.)
3997 (HANDLESIG): Remove.
3998 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4000 * make.h (EINTR_SET): Remove.
4001 (SA_RESTART): New macro.
4003 * arscan.c (ar_member_touch): Don't worry about EINTR.
4004 * function.c (func_shell): Likewise.
4005 * job.c (reap_children, free_child, new_job): Likewise.
4006 * main.c (main): Likewise.
4007 * remake.c (touch_file, name_mtime): Likewise.
4009 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4010 if fstat failed with errno!=EINTR, the error was ignored.
4012 * job.c (set_child_handler_action_flags): New function.
4013 (new_job): Use it to temporarily clear the SIGCHLD action flags
4014 while reading the token.
4016 2001-05-02 Paul D. Smith <psmith@gnu.org>
4018 * job.c (start_job_command): Don't add define/endef per-line flags
4019 to the top-level flags setting.
4021 2001-04-03 Paul D. Smith <psmith@gnu.org>
4023 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4024 bit on error, so check for odd return values, not non-0 return
4025 values.
4026 (VMS_get_member_info): Calculate the timezone differences correctly.
4027 Reported by John Fowler <jfowler@nyx.net>.
4030 2001-03-14 Paul D. Smith <psmith@gnu.org>
4032 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4033 value before invoking define_variable().
4034 Reported by John Fowler <jfowler@nyx.net>.
4036 2001-02-07 Paul D. Smith <psmith@gnu.org>
4038 * read.c (record_target_var): If we reset the variable due to a
4039 command-line variable setting overriding it, turn off the "append"
4040 flag.
4042 2001-01-17 Paul D. Smith <psmith@gnu.org>
4044 * variable.c (lookup_variable) [VMS]: When getting values from the
4045 environment, allocate enough space for the _value_ plus escapes,
4046 not enough space for the name plus escapes :-/.
4047 Reported by John Fowler <jfowler@nyx.net>.
4049 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4050 warnings that make generates, so it doesn't look like an error.
4051 Reported by Karl Berry <karl@gnu.org>.
4054 Fix for PR/2020: Rework appended target-specific variables. I'm
4055 fairly confident this algorithm is finally correct.
4057 * expand.c (allocated_variable_append): Rewrite. Instead of
4058 expanding each appended variable then adding all the expanded
4059 strings together, we append all the unexpanded values going up
4060 through the variable set contexts, then expand the final result.
4061 This behaves just like non-target-specific appended variable
4062 values, while the old way didn't in various corner cases.
4063 (variable_append): New function: recursively append the unexpanded
4064 value of a variable, walking from the outermost variable scope to
4065 the innermost.
4066 * variable.c (lookup_variable): Remove the code that looked up the
4067 variable set list if the found variable was "append". We don't
4068 need this anymore.
4069 (lookup_variable_in_set): Make this non-static so we can use it
4070 elsewhere.
4071 (try_variable_definition): Use lookup_variable_in_set() rather
4072 than faking out current_variable_set_list by hand (cleanup).
4073 * variable.h: Add a prototype for the now non-static
4074 lookup_variable_in_set().
4076 2000-11-17 Paul D. Smith <psmith@gnu.org>
4078 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4079 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4080 before throwing a fit.
4082 2000-11-17 Paul D. Smith <psmith@gnu.org>
4084 * read.c (readline): CRLF calculations had a hole, if you hit the
4085 buffer grow scenario just right. Reworked the algorithm to avoid
4086 the need for len or lastlen at all. Problem description with
4087 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4089 2000-10-24 Paul D. Smith <psmith@gnu.org>
4091 * gettext.c (SWAP): Declare this with the prototype, otherwise
4092 some systems don't work (non-32-bit? Reported for Cray T3E).
4093 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4095 2000-10-05 Paul D. Smith <psmith@gnu.org>
4097 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4098 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4100 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4102 2000-09-22 Paul D. Smith <psmith@gnu.org>
4104 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4105 parts of the real gettext.h here, and we expect to really include
4106 the real gettext.h later. If we keep this #define, it's ignored.
4108 2000-09-21 Paul D. Smith <psmith@gnu.org>
4110 * main.c (log_working_directory): Rework the text to use complete
4111 sentences, to make life simpler for the translators.
4113 2000-08-29 Paul D. Smith <psmith@gnu.org>
4115 * file.c (remove_intermediates): Print a debug message before we
4116 remove intermediate files, so the user (if she uses -d) knows
4117 what's going on.
4119 2000-08-21 Paul D. Smith <psmith@gnu.org>
4121 * variable.c (try_variable_definition): Change how we handle
4122 target-specific append variable defns: instead of just setting the
4123 value, expand it as an append _but_ only within the current
4124 target's context. Otherwise we lose all but the last value if the
4125 variable is appended more than once within the current target
4126 context. Fixes PR/1831.
4128 2000-08-16 Paul D. Smith <psmith@gnu.org>
4130 * function.c (func_shell): Nul-terminate the buffer before
4131 printing an exec error message (just in case it's not!).
4132 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4134 2000-07-25 Paul D. Smith <psmith@gnu.org>
4136 * job.c (construct_command_argv_internal): Add "~" to the list of
4137 sh_chars[] which disallow optimizing out the shell call.
4139 2000-07-23 Paul Eggert <eggert@twinsun.com>
4141 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4142 supersedes --disable-nsec-timestamps.
4143 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4144 * README: Remove --disable-nsec-timestamps.
4146 * filedef.h (struct file.low_resolution_time): New member.
4147 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4148 * remake.c (update_file_1):
4149 Avoid spurious rebuilds due to low resolution time stamps,
4150 generalizing the earlier code that applied only to archive members.
4151 (f_mtime): Archive members always have low resolution time stamps.
4153 * configure.in: Remove --disable-nsec-timestamps, as this has
4154 been superseded by .LOW_RESOLUTION_TIME.
4156 2000-07-23 Paul Eggert <eggert@twinsun.com>
4158 * configure.in (enable_nsec_timestamps): Renamed from
4159 make_cv_nsec_timestamps, since enable/disable options
4160 shouldn't be cached.
4162 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4163 and Paul Eggert <eggert@twinsun.com>
4165 * file.c (file_timestamp_now):
4166 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4167 so that clock_gettime is not linked unless needed.
4169 * filedef.h (FILE_TIMESTAMP_HI_RES):
4170 Remove definition; "configure" now does this.
4172 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4173 to before high resolution file timestamp check,
4174 since that check now uses uintmax_t.
4175 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4176 high resolution file timestamps.
4177 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4178 so that we don't link in clock_gettime unnecessarily.
4180 2000-07-17 Paul D. Smith <psmith@gnu.org>
4182 * i18n/ja.po: New version of the translation file.
4184 2000-07-07 Paul D. Smith <psmith@gnu.org>
4186 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4187 the offset calculation.
4188 (name_mtime): Replace EINTR test with EINTR_SET macro.
4190 2000-07-07 Paul Eggert <eggert@twinsun.com>
4192 Fix for PR/1811:
4194 * remake.c (update_file_1):
4195 Avoid spurious rebuilds of archive members due to their
4196 timestamp resolution being only one second.
4197 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4198 the clock's resolution being lower than file timestamps'.
4199 When warning about future timestamps, report only the discrepancy,
4200 not the absolute value of the timestamp and the current time.
4202 * file.c (file_timestamp_now): New arg RESOLUTION.
4203 * filedef.h (file_timestamp_now): Likewise.
4204 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4206 2000-07-05 Paul D. Smith <psmith@gnu.org>
4208 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4209 to listp. Fixes PR/1793.
4211 2000-06-26 Paul Eggert <eggert@twinsun.com>
4213 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4215 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4217 * remake.c (f_mtime): Remove unused var memtime.
4219 2000-06-25 Martin Buchholz <martin@xemacs.org>
4221 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4222 Ran spell-check on make.texinfo.
4224 2000-06-23 Paul D. Smith <psmith@gnu.org>
4226 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4227 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4228 * make.h: Define these macros.
4230 * Version 3.79.1 released.
4232 * configure.in: Add a new option, --disable-nsec-timestamps, to
4233 avoid using sub-second timestamps on systems that support it. It
4234 can lead to problems, e.g. if your makefile relies on "cp -p".
4235 * README.template: Document the issue with "cp -p".
4237 * config.guess, config.sub: Updated.
