14 static vars like buflen etc. are computed, so it must be static
15 as well. See Savannah bug #32511.
17 2011-09-16 Paul Smith <psmith@gnu.org>

40 2011-08-29 Paul Smith <psmith@gnu.org>
42 * expand.c (variable_expand_string): Always allocate a new buffer
43 for a string we're expanding. The string we're working on can get
44 freed while we work on it (for example if it's the value of a

66 2011-05-07 Eli Zaretskii <eliz@gnu.org>
68 * job.c (construct_command_argv_internal): Don't assume shellflags
69 is always non-NULL. Escape-protect characters special to the

108 (parse_variable_definition): Parse "!=" shell assignments.
109 * read.c (get_next_mword): Treat "!=" as a varassign word.
110 * function.c (fold_newlines): If trim_newlines is set remove all

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

545 * doc/make.texi (Undefine Directive): Describe the new directive.
547 * NEWS: Add a note about the new directive.
549 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
551 * implicit.c (pattern_search): Initialize file variables only
552 if we need to parse a rule that requires the second expansion.
554 2009-10-03 Paul Smith <psmith@gnu.org>
556 * make.h: Include <alloca.h> even on systems where __GNUC__ is
557 defined. Not sure why it was done the other way.
558 Requested by David Boyce <dsb@boyski.com>.
560 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
562 * dep.h (dep): Add the DONTCARE bitfield.
564 * filedef.h (file):Add the NO_DIAG bitfield.
566 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
567 not struct file (a file can be a dependency of many targets,
568 some don't care, some do).
570 * remake.c (update_goal_chain): Propagate DONTCARE from struct
571 dep to struct file before updating the goal and restore it
573 (update_file): Don't prune the dependency graph if this target
574 has failed but the diagnostics hasn't been issued.
575 (complain): Scan the file's dependency graph to find the file
576 that caused the failure.
577 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
578 whether to print diagnostics.
580 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
582 2009-09-28 Paul Smith <psmith@gnu.org>
584 * doc/make.texi (Pattern Intro): Move the match algorithm
585 discussion into the "Pattern Match" node.
586 (Pattern Match): Expand on the pattern rule matching algorithm.
588 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
590 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
591 much of the command line on a single pass.
593 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
595 * varible.c (create_pattern_var): Insert variables into the
596 PATTERN_VARS list in the shortest patterns first order.
598 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
599 used to sort the rules.
600 (stemlen_compare): Compare two tryrule elements.
601 (pattern_search): Sort the rules so that they are in the shortest
604 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
606 * doc/make.texi (Pattern-specific Variable Values): Describe the
607 new pattern-specific variables application order.
608 (Introduction to Pattern Rules): Describe the new pattern rules
611 * NEWS: Add a note about the new behavior.
613 2009-09-27 Paul Smith <psmith@gnu.org>
615 * doc/make.texi (Double-Colon): Mention that pattern rules with
616 double-colons have a different meaning. Savannah bug #27497.
618 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
620 * configh.dos.template: Remove unconditional definition of
621 SYS_SIGLIST_DECLARED.
622 Include <sys/version.h> because ports of GCC 4.3.0 and later no
623 longer include it, so macros like __DJGPP_MINOR__ are no longer
624 defined automatically.
626 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
627 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
628 instead of using the hardcoded ones.
629 (SUBDIRS): doc subdir added.
630 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
631 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
632 create html formated docs. texi2html may not be ported to DOS.
633 (make.info, make.dvi, make.ps, make.html): Make targets depend on
635 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
636 -I switch to look in ./ instead of ./doc.
637 (html): Target depend on html-recursive instead of make_1.html.
638 (make_1.html): Removed.
639 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
640 (all-recursive): Allow for more than one subdir in the build
642 (mostlyclean-recursive, clean-recursive, distclean-recursive)
643 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
644 (tags-recursive): Allow for more than one subdir in the build
646 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
647 targets. Enter into doc/ to produce the targets.
648 (all-am): $(INFO_DEPS) replaced by info.
650 2009-09-26 Paul Smith <psmith@gnu.org>
652 * read.c (record_files): Use free_ns() to free struct nameseq.
655 * rule.c (freerule): Use free_dep_chain().
657 * read.c (record_files): Free FILENAMES chain for implicit rules.
658 (eval): Static pattern targets go into the string cache.
660 * function.c (string_glob): Free NAME in the nameseq chain.
662 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
664 * implicit.c (pattern_search): Terminate early if we haven't
665 found any rules to try (performance improvement).
667 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
669 * implicit.c (pattern_search): Merge three parallel arrays,
670 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
671 of struct TRYRULE. In the old version the latter two arrays
672 had insufficient length.
674 2009-09-24 Paul Smith <psmith@gnu.org>
676 * implicit.c (pattern_search): Add back support for order-only
677 prerequisites for secondary expansion implicit rules, that were
678 accidentally dropped. If we find a "|", enable order-only mode
679 and set IGNORE_MTIME on all deps that are seen afterward.
680 (pattern_search): Fix memory leaks: for intermediate files where
681 we've already set the file variable and pattern variable sets, be
682 sure to either save or free them as appropriate.
684 2009-09-23 Paul Smith <psmith@gnu.org>
686 Rework the way secondary expansion is stored, for efficiency.
687 This changes secondary expansion so that ONLY WHEN we know we have
688 a possibility of needing secondary expansion, do we defer the
689 secondary expansion. This means more parsing the deps but we use
690 a lot less memory (due to the strcache). Also, this fixes
693 * read.c (eval): Don't parse the dep string here anymore.
694 (record_files): Take the dep argument as an unparsed string. If
695 secondary expansion is enabled AND the prereq string has a '$' in
696 it, then set NEED_2ND_EXPANSION and keep the entire string.
697 Otherwise, parse the dep string here to construct the dep list
698 with the names in the strcache.
700 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
701 duplicate the name string (others are in the strcache).
703 * implicit.c: Remove struct idep and free_idep_chain(): unused.
704 (struct patdeps): New structure to store prereq information.
705 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
706 which prerequisites need expansion, and expand only those.
708 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
709 and enter_prereqs(). split_prereqs() takes a fully-expanded string
710 and splits it into a DEP list, handling order-only prereqs.
711 (enter_prereqs): This function enters a list of DEPs into the file
712 database. If there's a stem defined, expand any pattern chars.
713 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
714 set. Use the above functions.
715 (snap_deps): Only perform second expansion on prereqs that need it,
716 as defined by the NEED_2ND_EXPANSION flag.
717 (print_prereqs): New function to print the prereqs
718 (print_file): Call print_prereqs() rather than print inline.
720 * hash.h (STRING_COMPARE): Take advantage of strcache() by
722 (STRING_N_COMPARE): Ditto.
723 (ISTRING_COMPARE): Ditto.
725 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
726 (parse_file_seq): Return void*
727 * read.c (parse_file_seq): Return void*.
728 (eval): Invoke macroized version of parse_file_seq()
729 * default.c (set_default_suffixes): Ditto.
730 * file.c (split_prereqs): Ditto.
731 * function.c (string_glob): Ditto.
732 * main.c (main): Ditto.
733 * rule.c (install_pattern_rule): Ditto.
735 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
737 2009-09-16 Paul Smith <psmith@gnu.org>
739 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
741 * dep.h: Create alloc_dep() / free_dep() macros.
743 * implicit.c (pattern_search): Take advantage of the new
744 parse_file_seq() to add the directory prefix to each prereq.
746 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
747 all. Avoid reversing chains. Support adding prefixes.
748 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
749 cached/non-cached results.
750 (eval): Remove multi_glob() & invoke new parse_file_seq().
751 * rule.c (install_pattern_rule): Ditto.
752 * main.c (main): Ditto.
753 * implicit.c (pattern_search): Ditto.
754 * function.c (string_glob): Ditto.
755 * file.c (parse_prereqs): Ditto.
756 * default.c (set_default_suffixes): Ditto.
758 * variable.c (parse_variable_definition): Don't run off the end of
759 the string if it ends in whitespace (found with valgrind).
761 * commands.c (set_file_variables): Keep space for all targets in
762 $? if -B is given (found with valgrind).
764 2009-09-15 Paul Smith <psmith@gnu.org>
766 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
767 (xcalloc): Add new function.
768 * make.h: New declarations.
770 * ar.c (ar_glob_match): New calling method for concat().
771 * main.c (main): Ditto.
772 (decode_env_switches): Ditto.
773 * read.c (eval_makefile): Ditto.
774 (tilde_expand): Ditto.
775 (parse_file_seq): Ditto.
776 * variable.c (target_environment): Ditto.
777 (sync_Path_environment): Ditto.
779 * ar.c (ar_glob_match): Use xcalloc().
780 * dir.c (file_impossible): Ditto.
781 * file.c (enter_file): Ditto.
782 * job.c (new_job): Ditto.
783 * read.c (parse_file_seq): Ditto.
784 * vmsfunctions.c (opendir): Ditto.
786 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
788 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
789 inside the loop that looks up environment for PATH.
791 2009-08-31 Eli Zaretskii <eliz@gnu.org>
793 * function.c (windows32_openpipe): Update envp after calling
794 sync_Path_environment.
796 2009-08-02 Paul Smith <psmith@gnu.org>
798 * remake.c (notice_finished_file): Ensure file->cmds is not null
799 before looping through them. Fixes Savannah bug #21824.
801 * doc/make.texi (Wildcard Examples): Clarify when objects is
802 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
803 (Include): Clarify the behavior of -include.
804 Fixes Savannah bug #18963.
806 2009-08-01 Paul Smith <psmith@gnu.org>
808 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
809 etc. come on the command line. Fixes Savannah bug #27093.
811 * expand.c (expand_argument): If the argument is large enough use
812 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
814 * variable.c (do_variable_definition): Avoid using alloca() to
815 hold values, which can be large. Fixes Savannah bug #23960.
817 * job.c (new_job): Use memmove() instead of strcpy() since both
818 pointers are in the same memory block. Fixes Savannah bug #27148.
819 Patch by Petr Machata.
821 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
823 * job.c (construct_command_argv_internal): Add "ulimit" and
824 "unset" to the sh_cmds for Unixy shells.
826 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
828 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
829 that set make_cv_sys_gnu_glob, so they are also correctly set
830 when the cache has been populated before.
832 2009-07-04 Eli Zaretskii <eliz@gnu.org>
834 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
835 exist, as realpath(3) does where it's supported.
837 2006-07-04 Eli Zaretskii <eliz@gnu.org>
839 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
840 (abspath): Support systems that define HAVE_DOS_PATHS (have
841 drive letters in their file names). Use IS_PATHSEP instead of a
842 literal '/' comparison. Fixes Savannah bug #26886.
844 2009-06-14 Paul Smith <psmith@gnu.org>
846 * remake.c (update_file_1): Remember the original file we marked
847 as updating, so we can clear that flag again. If we find a target
848 via vpath, FILE might change.
849 (check_dep): Ditto. Fixes Savannah bug #13529.
850 Patch by Reid Madsen <reid.madsen@tek.com>.
852 2009-06-13 Paul Smith <psmith@gnu.org>
854 * doc/make.texi (MAKEFILES Variable): Be explicit that files
855 included by MAKEFILES cannot give default goals.
856 * read.c (eval): If set_default is not set, pass the no-default-goal
857 value when we read included makefiles. Fixes Savannah bug #13401.
859 * ar.c (ar_name): Ensure that targets with empty parens aren't
860 considered archive member references: archive members must have a
861 non-empty "member" string. Fixes Savannah bug #18435.
863 * function.c (string_glob): Rely on multi_glob() to determine
864 whether files exist or not. Remove call to file_exists_p() which
865 is not always correct. Fixes Savannah bug #21231.
866 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
867 then only files that really exist will be returned.
868 * dep.h: Add new argument to multi_glob().
869 * rule.c (install_pattern_rule): Ditto.
870 * read.c (eval): Ditto.
871 * main.c (main): Ditto.
872 * implicit.c (pattern_search): Ditto.
873 * file.c (parse_prereqs): Ditto.
874 * default.c (set_default_suffixes): Ditto.
876 2009-06-09 Paul Smith <psmith@gnu.org>
878 * commands.c (set_file_variables): If always_make_flag is set,
879 always add the prereq to $?. Fixes Savannah bug #17825.
881 * remake.c (update_file_1): When rebuilding deps of FILE, also try
882 to rebuild the deps of all the also_make targets for that file.
883 Fixes Savannah bug #19108.
885 * implicit.c (pattern_search): Undo test for is_target, added by
886 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
887 Rule Search Algorithm". Fixes Savannah bug #17752.
889 * main.c (clean_jobserver): Clear the jobserver_fds options and
890 set job_slots to the default when we clean up.
891 (define_makeflags): Return the new MAKEFLAGS value.
892 (main): Reset MAKEFLAGS in the environment when we re-exec.
893 Fixes Savannah bug #18124.
895 2009-06-08 Paul Smith <psmith@gnu.org>
897 * read.c (eval): Collapse continuations post-semicolon on target-
898 specific variables. Fixes Savannah bug #17521.
900 2009-06-07 Paul Smith <psmith@gnu.org>
902 * job.c (reap_children): For older systems without waitpid() (are
903 there any of these left?) run wait(2) inside EINTRLOOP to handle
904 EINTR errors. Fixes Savannah bug #16401.
906 * (various): Debug message cleanup. Fixes Savannah bug #16469.
908 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
910 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
911 not the end, to catch second expansion $(eval ...) defining new
912 target/prereq relationships during snap_deps.
913 Fixes Savannah bug #24622.
915 * read.c (record_files): The second-expansion "f->updating" hack
916 was not completely correct: if assumed that the target with
917 commands always had prerequisites; if one didn't then the ordering
918 was messed up. Fixed for now to use f->updating to decide whether
919 to preserve the last element in the deps list... but this whole
920 area of constructing and reversing the deps list is too confusing
921 and needs to be reworked. Fixes Savannah bug #21198.
923 2009-06-06 Paul Smith <psmith@gnu.org>
925 * hash.c (hash_insert): Remove useless test for NULL.
926 Fixes Savannah bug #21823.
928 * make.h: Move SET_STACK_SIZE determination to make.h.
929 * main.c (main): New global variable, STACK_LIMIT, holds the
930 original stack limit when make was started.
931 * job.c (start_job_command): Reset the stack limit, if we changed it.
932 Fixes Savannah bug #22010.
934 * remake.c (check_dep): Only set the target's state to not-started
935 if it's not already running. Found this while testing -j10 builds
936 of glibc: various targets were being rebuilt multiple times.
937 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
940 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
941 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
944 2009-06-04 Paul Smith <psmith@gnu.org>
946 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
948 * maintMakefile: Modify access of config and gnulib Savannah
949 modules to use GIT instead of CVS.
951 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
952 Fixes Savannah bug #24655.
954 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
955 this can happen during some invocations of $(eval ...) for example.
956 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
958 2009-06-02 Paul Smith <psmith@gnu.org>
960 * configure.in: Check for fileno()
961 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
962 for the makefile file so invocations of $(shell ...) don't inherit it.
963 Fixes Savannah bug #24277.
965 2009-06-01 Paul Smith <psmith@gnu.org>
967 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
968 expansion was handled incorrectly. Rework the default goal
969 handling to save the variable only. Remove default_goal_file and
971 * read.c (eval): Check default_goal_var, not default_goal_name.
972 * read.c (record_target_var): Don't check default_goal_file here.
974 2009-05-31 Paul Smith <psmith@gnu.org>
976 * main.c (main): Expand the .DEFAULT_GOAL variable before using
977 it, and if the multi_glob() returns nothing (say it expanded to
978 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
980 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
981 $(and ..) to the reference. Fixes Savannah bug #25694.
983 * make.1: Be clear that some recipes will be executed even with -n.
984 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
986 * doc/make.texi (Override Directive): Make more clear how
987 overrides and appends interact.
988 Elucidates part of Savannah bug #26207.
990 * read.c (record_target_var): Don't reset the origin on
991 target-specific variables; try_variable_definition() will handle
992 this correctly. Fixes Savannah bug #26207.
994 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
995 Fixes Savannah bug #25712.
997 * implicit.c (pattern_search): Keep a pointer to the beginning of
998 the filename and save that instead of the constructed pointer.
999 Fixes Savannah bug #26593.
1000 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1002 2009-05-30 Paul Smith <psmith@gnu.org>
1004 * doc/make.texi (Multi-Line): Add a description of the new abilities
1005 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1006 "command sequence" vs. "recipe" syntax.
1007 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1008 after a define, to create variables with those flavors.
1010 2009-05-25 Paul Smith <psmith@gnu.org>
1012 Reworked the parser for variable assignments to allow multiple
1013 modifiers, and in any order. Also allows variable and
1014 prerequisites to be modifier names ('export', 'private', etc.)
1016 * NEWS: Add notes about user-visible changes.
1018 * read.c (struct vmodifiers): Remember what modifiers were seen.
1019 (parse_var_assignment): New function to parse variable assignments.
1020 (eval): Call the new function. Handle variable assignments earlier.
1022 * variable.c (parse_variable_definition): Only parse; don't create var.
1023 (assign_variable_definition): Call parse, then create the var.
1025 2009-05-24 Paul Smith <psmith@gnu.org>
1027 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1028 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1030 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1032 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1033 Fixes Savannah bug #25412.
1035 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1036 prototype for xmalloc.
1037 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1038 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1039 Loop over an array of extensions, instead of duplicating the same
1040 code inline. Use SearchPath followed by CreateFile, instead of
1041 the obsolete OpenFile. Fixes Savannah bug #17277.
1042 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1043 to `find_file'. Fixes Savannah bug #25662.
1045 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1047 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1048 Fixes Savannah bug #20495.
1050 2009-02-28 Ralf Wildenhues <address@hidden>
1052 * doc/make.texi (Instead of Execution): Document interaction of
1053 -t with phony targets.
1055 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1057 Introduce a new keyword "private" which applies to target-specific
1058 variables and prevents their values from being inherited.
1060 * variable.h (struct variable): Add private_var flag to each variable.
1061 Add a flag to specify which list entry switches to the parent target.
1062 * variable.c (define_variable_in_set): Initialize private_var flag.
1063 (lookup_variable): Skip private variables in parent contexts.
1064 (initialize_file_variables): Set next_is_parent appropriately.
1065 (print_variable): Show the private_var flag.
1066 * read.c (eval): Recognize the private keyword.
1067 (record_target_var): Set private_var.

1144 HAVE_DECL_SYS_SIGLIST.
1146 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP

1176 * variable.c (do_variable_definition): Allow $(SHELL) to expand to

1182 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1183 pathnames, with const strings.

1216 2007-09-10 Paul Smith <psmith@gnu.org>
1218 * commands.c (print_commands): Don't print an extra line in the
1219 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1221 * read.c (construct_include_path): Add the full string to the cache; we
1222 were chopping the last char.

1232 * main.c (main): Create the .RECIPEPREFIX special variable.
1233 * read.c (eval): Remove the cmd_prefix characters from the command
1234 scripts here, so they're not stored in the commands array at all,
1235 rather than waiting and stripping them out during command construction.
1236 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1238 2007-08-15 Paul Smith <psmith@gnu.org>
1240 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1241 file has had the section info removed, so add some to make.texi

1244 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1246 * remake.c (check_dep): Reset the target state for intermediate

1266 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1267 Fixes Savannah bug #20452.

1304 Dave Korn <dave.korn@artimi.com>
1306 2007-05-08 Paul Smith <psmith@gnu.org>
1308 Fix Savannah bug #19656:
1310 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1312 * make.h: Change all case-insensitive string compares to use
1313 strcasecmp() (from POSIX). If we don't have that but do have one
1314 of the others, define strcasecmp to be one of those instead. If
1315 we don't have any, declare a prototype for our own version.
1317 * misc.c (strcasecmp): Use this if we can't find any native
1318 case-insensitive string comparison function.
1319 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1320 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1322 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1323 strcasecmp() instead of stricmp().
1324 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1325 instead of strcmpi().
1326 * acinclude.m4: Remove the strcasecmp() check from here.
1328 2007-03-21 Paul Smith <psmith@gnu.org>
1330 * configure.in: Don't turn on case-insensitive file system support
1331 if --disable-... is given. Fixes Savannah bug #19348.
1333 2007-03-19 Paul Smith <psmith@gnu.org>
1335 * ALL: Use the strcache for all file name strings, or other
1336 strings which we will never free. The goal is to save memory by
1337 avoiding duplicate copies of strings. However, at the moment this
1338 doesn't save much memory in most situations: due to secondary
1339 expansion we actually save prerequisite lists twice (once before
1340 the secondary expansion, and then again after it's been parsed
1341 into individual file names in the dep list). We will resolve this
1342 in a future change, by doing the parsing up-front for targets
1343 where secondary expansion is not set.
1345 Moving things into the strcache also allows us to use const
1346 pointers in many more places.
1348 2007-01-03 Paul Smith <psmith@gnu.org>
1350 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1351 the function, not just the first. Fixes Savannah bug #18680.
1353 2006-11-18 Paul Smith <psmith@gnu.org>
1355 * strcache.c (strcache_add_len): Don't allocate a new buffer
1356 unless the string is not already nil-terminated. Technically this
1357 is a violation of the standard, since we may be passed an array
1358 that is not long enough to test one past. However, in make this
1359 is never true since we only use nil-terminated strings or
1360 sub-strings thereof.
1362 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1364 * main.c: New global cmd_prefix, defaults to '\t'.
1365 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1368 * dir.c: Constified.
1369 (dir_contents_file_exists_p): Check for an error return from
1370 readdir(), just in case.
1372 * commands.c: Constified.
1373 * default.c: Constified.
1374 * expand.c: Constified.
1375 * function.c: Partial constification.

1380 * w32/pathstuff.c: Partial constification.
1382 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1384 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1385 backslashes and drive letters as absolute.
1387 2006-10-22 Paul Smith <psmith@gnu.org>
1389 * main.c (struct command_switch): Use const and void*.
1391 2006-10-21 Paul Smith <psmith@gnu.org>
1394 * arscan.c: Constified.
1396 2006-09-30 Paul Smith <psmith@gnu.org>
1398 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1399 point to lastword since the example was updated.
1400 Fixes Savannah bug #16304.
1401 (Secondary Expansion): Correct example description.
1402 Fixes Savannah bug #16468.
1403 (Makefile Contents): Clarify that comments cannot appear within
1404 variable references or function calls.
1405 Fixes Savannah bug #16577.
1406 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1407 Fixes Savannah bug #17701.
1408 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1410 prerequisites. Fixes Savannah bug #17880.
1411 (Rule Syntax): "lise" -> "list"

1413 (Splitting Lines): ditto.

1416 considered changed, for the purposes of $?.
1417 Fixes Savannah bug #16051.
1419 * make.1: Remove extraneous "+".
1420 Fixes Savannah bug #16652.

1437 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1438 sh_chars_sh for Windows platforms that emulate Unix.
1440 2006-05-07 Paul D. Smith <psmith@gnu.org>
1442 * README.OS2.template: Updates provided by Andreas Buening

1472 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned

1474 don't need to be cast. Also remove (char *) casts of arguments to
1477 * configure.in: Remove checks for memcpy/memmove/strchr.
1479 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

1489 2006-04-06 Paul D. Smith <psmith@gnu.org>
1491 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1492 require an ISO C 1989 standard compiler and runtime library.

1530 2006-03-23 Paul D. Smith <psmith@gnu.org>
1532 * configure.in: Look for build.sh.in in $srcdir so it will be
1533 built for remote configurations as well.

1594 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1595 listed non-existent files as changed. Turns out there's a bug in
1596 the Linux kernel builds which means that this change causes
1597 everything to rebuild every time. We will re-introduce this fix
1598 in the next release, to give them time to fix their build system.
1599 Fixes Savannah bug #16002.
1600 Introduces Savannah bug #16051.
1602 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1603 we *don't* find UNIX "/".
1604 Reported by David Ergo <david.ergo@alterface.com>
1606 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1608 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1609 locator function find_and_set_default_shell if SHELL came from the
1612 2006-02-20 Paul D. Smith <psmith@gnu.org>
1614 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1615 to be null; don't core in that case.
1617 2006-02-19 Paul D. Smith <psmith@gnu.org>
1619 * commands.c (set_file_variables): Realloc, not malloc, the static
1620 string values to avoid memory leaks.
1622 * expand.c (recursively_expand_for_file): Only set reading_file to
1623 an initialized value.
1625 * implicit.c (pattern_search): We need to make a copy of the stem
1626 if we get it from an intermediate dep, since those get freed.
1628 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1630 (enter_file) [VMS]: Ditto.
1631 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1633 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1635 * job.c (construct_command_argv_internal): Fix last change.
1637 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1638 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1639 the calls to _beginthreadex.
1641 * expand.c (recursively_expand_for_file): Initialize `save' to
1642 prevent compiler warnings.
1644 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1646 * job.c (construct_command_argv_internal): Don't create a temporary
1647 script/batch file if we are under -n. Call _setmode to switch the
1648 script file stream to text mode.
1650 2006-02-17 Paul D. Smith <psmith@gnu.org>
1652 * variable.c (merge_variable_set_lists): Don't try to merge the
1653 global_setlist. Not only is this useless, but it can lead to
1654 circularities in the linked list, if global_setlist->next in one
1655 list gets set to point to another list which also ends in
1657 Fixes Savannah bug #15757.
1659 2006-02-15 Paul D. Smith <psmith@gnu.org>
1661 Fix for Savannah bug #106.
1663 * expand.c (expanding_var): Keep track of which variable we're
1664 expanding. If no variable is being expanded, it's the same as
1666 * make.h (expanding_var): Declare it.
1667 * expand.c (recursively_expand_for_file): Set expanding_var to the
1668 current variable we're expanding, unless there's no file info in
1669 it (could happen if it comes from the command line or a default
1670 variable). Restore it before we exit.
1671 * expand.c (variable_expand_string): Use the expanding_var file
1672 info instead of the reading_file info.
1673 * function.c (check_numeric): Ditto.
1675 (func_wordlist): Ditto.
1676 (func_error): Ditto.
1677 (expand_builtin_function): Ditto.
1678 (handle_function): Ditto.
1680 2006-02-14 Paul D. Smith <psmith@gnu.org>
1682 * read.c (eval): Even if the included filenames expands to the
1683 empty string we still need to free the allocated buffer.
1685 * implicit.c (pattern_search): If we allocated a variable set for
1686 an impossible file, free it.
1687 * variable.c (free_variable_set): New function.
1688 * variable.h: Declare it.
1690 * read.c (read_all_makefiles): Makefile names are kept in the
1691 strcache, so there's never any need to alloc/free them.
1694 * main.c (main): Add "archives" to the .FEATURES variable if
1695 archive support is enabled.
1696 * doc/make.texi (Special Variables): Document it.
1698 2006-02-13 Paul D. Smith <psmith@gnu.org>
1700 * implicit.c (pattern_search): Add checking for DOS pathnames to
1701 the pattern rule target LASTSLASH manipulation.
1702 Fixes Savannah bug #11183.

1706 * (ALL FILES): Updated copyright and license notices.
1708 2006-02-10 Paul D. Smith <psmith@gnu.org>
1710 A new internal capability: the string cache is a read-only cache
1711 of strings, with a hash table interface for fast lookup. Nothing
1712 in the cache will ever be freed, so there's no need for reference
1713 counting, etc. This is the beginning of a full solution for
1714 Savannah bug #15182, but for now we only store makefile names here.
1716 * strcache.c: New file. Implement a read-only string cache.
1717 * make.h: Add prototypes for new functions.
1718 * main.c (initialize_global_hash_tables): Initialize the string cache.
1719 (print_data_base): Print string cache stats.
1720 * read.c (eval_makefile): Use the string cache to store makefile
1721 names. Rewrite the string allocation to be sure we free everything.
1723 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1725 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1726 directory time stamp didn't change, except on FAT filesystems.
1727 Suggested by J. David Bryan <jdbryan@acm.org>.
1729 2006-02-09 Paul D. Smith <psmith@gnu.org>
1731 * function.c (func_or): Implement a short-circuiting OR function.
1732 (func_and): Implement a short-circuiting AND function.
1733 (function_table_init): Update the table with the new functions.
1734 * doc/make.texi (Conditional Functions): Changed the "if" section
1735 to one on general conditional functions. Added documentation for
1736 $(and ...) and $(or ...) functions.
1737 * NEWS: Note new $(and ...) and $(or ...) functions.
1739 2006-02-08 Boris Kolpackov <boris@kolpackov.net>

1742 * job.c (new_job): Cache dontcare flag.
1743 * job.c (reap_children): Use cached dontcare flag instead of the
1744 one in struct file. Fixes Savannah bug #15641.
1746 2006-02-06 Paul D. Smith <psmith@gnu.org>
1748 * vpath.c (selective_vpath_search): If the file we find has a
1749 timestamp from -o or -W, use that instead of the real time.
1750 * remake.c (f_mtime): If the mtime is a special token from -o or
1751 -W, don't overwrite it with the real mtime.
1752 Fixes Savannah bug #15341.
1754 Updates from Markus Mauhart <qwe123@chello.at>:
1756 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1757 (process_signal, process_last_err, process_exit_code): Manage
1758 invalid handle values.
1759 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1760 manage invalid handles; remove them.
1761 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1762 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1763 * README.cvs: Updates for building from CVS.
1765 2006-02-05 Paul D. Smith <psmith@gnu.org>
1767 * file.c (enter_file): Keep track of the last double_colon entry,
1768 to avoid walking the list every time we want to add a new one.
1769 Fixes Savannah bug #15533.
1770 * filedef.h (struct file): Add a new LAST pointer.
1772 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1773 the comparison. For 64-bits systems the result of the subtraction
1774 might not fit into an int. Use comparison instead.
1775 Fixes Savannah bug #15534.
1777 * doc/make.texi: Update the chapter on writing commands to reflect
1778 the changes made in 3.81 for backslash/newline and SHELL handling.
1780 2006-02-01 Paul D. Smith <psmith@gnu.org>
1782 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1783 variable st is not used when it's not initialized.

1798 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1800 * remake.c (update_goal_chain): Set g->changed instead of
1801 incrementing it, as it is only 8-bit wide, and could overflow if
1802 many commands got started in update_file.
1804 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1806 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1807 MAXIMUM_WAIT_OBJECTS.
1808 (process_wait_for_any_private): Change dimension of handles[]
1809 array to MAXIMUM_WAIT_OBJECTS.

1815 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1816 are already more children than sub_proc.c can handle, behave as if
1817 the load were too high.
1818 (start_job_command): Fix a typo in error message when process_easy
1821 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1823 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1824 the shell is not sh.exe.
1826 * job.c (create_batch_file): Renamed from create_batch_filename;
1827 all callers changed. Don't close the temporary file; return its
1828 file descriptor instead. New arg FD allows to return the file
1830 (construct_command_argv_internal): Use _fdopen instead of fopen to
1831 open the batch file.
1833 2006-01-04 Paul D. Smith <psmith@gnu.org>
1835 * readme.vms: Updates for case-insensitive VMS file systems from
1836 Hartmut Becker <Hartmut.Becker@hp.com>.

1856 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1857 disable warnings for MSC.
1858 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1860 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1862 * doc/make.texi (Execution): Add a footnote about changes in
1863 handling of backslash-newline sequences. Mention the differences
1864 on MS-DOS and MS-Windows.
1866 * NEWS: More details about building the MinGW port and a pointer
1867 to README.W32. Fix the section name that describes the new
1868 backward-incompatible processing of backslash-newline sequences.
1869 The special processing of SHELL set to "cmd" is only relevant to
1870 MS-Windows, not MS-DOS.
1872 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1874 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1875 to DWORD, to avoid compiler warnings.
1876 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1877 use %ld in format, to avoid compiler warnings.

1891 * read.c (record_target_var): Initialize variable's export field
1892 with v_default instead of leaving it "initialized" by whatever
1893 garbage happened to be on the heap.

1897 * make.1: Fix some display errors and document all existing options.
1898 Patch by Mike Frysinger <vapier@gentoo.org>.
1900 2005-12-11 Paul D. Smith <psmith@gnu.org>
1902 * implicit.c (pattern_search): If 2nd expansion is not set for
1903 this implicit rule, replace the pattern with the stem directly,
1904 and don't re-expand the variable list. Along with the other
1905 .SECONDEXPANSION changes below, fixes bug #13781.
1907 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1909 * implicit.c (pattern_search): Mark other files that this rule
1910 builds as targets so that they are not treated as intermediates
1911 by the pattern rule search algorithm. Fixes bug #13022.
1913 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1915 * remake.c (notice_finished_file): Propagate the change of

1935 * read.c (record_files): Don't set deps flags if there are no deps.
1936 * maintMakefile: We only need to build the templates when we are
1937 creating a distribution, so don't do it for "all".
1939 2005-10-24 Paul D. Smith <psmith@gnu.org>
1941 Make secondary expansion optional: its enabled by declaring the
1942 special target .SECONDEXPANSION.
1944 * NEWS: Update information on second expansion capabilities.
1945 * doc/make.texi (Secondary Expansion): Document the
1946 .SECONDEXPANSION special target and its behavior.

1949 (free_dep_chain): Declare a prototype.
1950 * file.c (parse_prereqs): New function: break out some complexity
1952 (expand_deps): If we aren't doing second expansion, replace % with
1953 the stem for static pattern rules. Call the new function.
1954 * filedef.h (parse_prereqs): Declare a prototype.
1955 * implicit.c (pattern_search): Initialize the new staticpattern
1957 * main.c (second_expansion): Declare a global variable to remember
1958 if the special target has been seen. Initialize the new
1959 staticpattern field for prerequisites.
1960 * make.h: Extern for second_expansion.
1961 * misc.c (free_dep_chain): New function: frees a struct dep list.
1962 * read.c (read_all_makefiles): Initialize the staticpattern field.

1964 (record_files): Check for the .SECONDEXPANSION target and set
1965 second_expansion global if it's found.
1966 Use the new free_dep_chain() instead of doing it by hand.
1967 Set the staticpattern field for prereqs of static pattern targets.
1969 2005-10-16 Paul D. Smith <psmith@gnu.org>
1971 * main.c (main): Set CURDIR to be a file variable instead of a
1972 default, so that values of CURDIR inherited from the environment
1973 won't override the make value.
1975 2005-09-26 Paul D. Smith <psmith@gnu.org>
1977 * job.c (construct_command_argv_internal): If the line is empty
1978 remember to free the temporary argv strings.
1981 2005-09-16 Paul D. Smith <psmith@gnu.org>
1983 * job.c (start_job_command): The noerror flag is a boolean (single
1984 bit); set it appropriately.
1985 Reported by Mark Eichin <eichin@metacarta.com>
1987 2005-08-29 Paul D. Smith <psmith@gnu.org>
1989 * function.c (func_error): On Windows, output from $(info ...)
1990 seems to come in the wrong order. Try to force it with fflush().
1992 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1994 * read.c (record_files): Move code that sets stem for static
1995 pattern rules out of the if (!two_colon) condition so it is
1996 also executed for two-colon rules. Fixes Savannah bug #13881.
1998 2005-08-08 Paul D. Smith <psmith@gnu.org>
2000 * make.h: Don't test that __STDC__ is non-0. Some compilers
2001 (Windows for example) set it to 0 to denote "ISO C + extensions".
2004 2005-08-07 Paul D. Smith <psmith@gnu.org>
2006 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2007 conditional (slightly different version of a fix from Eli).
2009 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2010 If make is running in parallel without -k and two jobs die in a
2011 row, but not too close to each other, then make will quit without
2012 waiting for the rest of the jobs to die.
2014 * main.c (die): Don't reset err before calling reap_children() the
2015 second time: we still want it to be in the error condition.
2016 * job.c (reap_children): Use a static variable, rather than err,
2017 to control whether or not the error message should be printed.
2019 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2021 * w32/subproc/sub_proc.c: Include signal.h.
2022 (process_pipe_io, process_file_io): Pass a pointer to a local
2023 DWORD variable to GetExitCodeProcess. If the exit code is
2024 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2026 * job.c [WINDOWS32]: Include windows.h.
2027 (main_thread) [WINDOWS32]: New global variable.
2028 (reap_children) [WINDOWS32]: Get the handle for the main thread

2031 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2032 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2033 doing anything else. When we are done, close the main thread
2034 handle and exit with status 130.

2038 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2041 * main.c (find_and_set_default_shell): If found a DOSish shell,
2042 set sh_found and the value of default_shell, and report the
2043 findings in debug mode.
2045 * job.c (construct_command_argv_internal): Check unixy_shell, not
2046 no_default_sh_exe, to decide whether to use Unixy or DOSish
2049 * README.W32: Update with info about the MinGW build.
2051 * build_w32.bat: Support MinGW.
2053 * w32/subproc/build.bat: Likewise.
2055 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2056 printing DWORD args.
2058 * function.c (windows32_openpipe): Fix format strings for printing
2061 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2063 (start_job_command): Fix format string for printing the result of
2065 (start_job_command) [WINDOWS32]: Do not define.
2066 (exec_command): Fix format string for printing HANDLE args.
2068 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2069 to avoid compiler warnings.
2070 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2071 (Note: some of these fixes were submitted independently by J. Grant)

2075 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2076 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2077 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2079 2005-07-15 Paul Smith <psmith@gnu.org>
2081 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2082 we don't have a POSIX shell, then revert to the old
2083 backslash-newline behavior (where they are stripped).
2086 2005-07-08 Paul D. Smith <psmith@gnu.org>
2088 * config.h.W32.template: Reorder to match the standard config.h,
2089 for easier comparisons.
2090 From J. Grant <jg@jguk.org>
2092 * maintMakefile: Remove .dep_segment before overwriting it, in
2093 case it's not writable or noclobber is set.
2094 * expand.c (variable_expand_string): Cast result of pointer
2095 arithmetic to avoid a warning.
2096 * main.c (switches): Add full-fledged final initializer.
2098 2005-07-06 Paul D. Smith <psmith@gnu.org>
2100 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2101 * signame.c (strsignal): If we found _sys_siglist[] or
2102 __sys_siglist[] use those instead of sys_siglist[].
2103 From Albert Chin <china@thewrittenword.com>
2105 2005-07-04 Paul D. Smith <psmith@gnu.org>
2107 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2108 globfree(); set up to use the GNU versions.
2109 From Martin Zinser <zinser@zinser.no-ip.info>
2111 2005-07-03 Paul D. Smith <psmith@gnu.org>
2113 From J. Grant <jg@jguk.org>:
2115 * README.W32.template: Update the Windows and tested MSVC versions.
2116 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2117 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2118 * build_w32.bat: Ditto.
2119 * w32/subproc/build.bat: Ditto.
2121 2005-06-28 Paul D. Smith <psmith@gnu.org>
2123 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2124 declaration was checked but not present.
2126 2005-06-27 Paul D. Smith <psmith@gnu.org>
2128 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2129 to unsigned long. Fixes Savannah bug #13550.
2131 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2132 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2133 Fixes Savannah bug #13551.
2135 2005-06-26 Paul D. Smith <psmith@gnu.org>
2137 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2138 it if ANSI_STRING is not set.
2140 2005-06-25 Paul D. Smith <psmith@gnu.org>
2142 * read.c (eval): If no filenames are passed to any of the
2143 "include" variants, don't print an error.
2144 * doc/make.texi (Include): Document this.
2145 Fixes Savannah bug #1761.
2147 * job.c (construct_command_argv_internal): Sanitize handling of
2148 backslash/newline pairs according to POSIX: that is, keep the
2149 backslash-newline in the command script, but remove a following
2150 TAB character, if present. In the fast path, make sure that the
2151 behavior matches what the shell would do both inside and outside
2152 of quotes. In the slow path, quote the backslash and put a
2153 literal newline in the string.
2154 Fixes Savannah bug #1332.
2155 * doc/make.texi (Execution): Document the new behavior and give
2157 * NEWS: Make a note of the new behavior.
2159 * make.h [WINDOWS32]: #include <direct.h>.
2160 Fixes Savannah bug #13478.
2162 * remake.c (name_mtime): If the stat() of a file fails and the -L
2163 option was given and the file is a symlink, take the best mtime of
2164 the symlink we can get as the mtime of the file and don't fail.
2165 Fixes Savannah bug #13280.
2167 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2168 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2169 inside a variable reference. Make this function static as it's
2171 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2172 parsing an unexpanded line looking for semicolons.
2173 Fixes Savannah bug #1454.
2174 * misc.c (remove_comments): Move this to read.c and make it static
2175 as it's only used there. Call find_char_unquote() with new arg.
2176 * make.h: Remove prototypes for find_char_unquote() and
2177 remove_comments() since they're static now.
2179 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2180 its export flag and obtain its value. When we need to re-exec,
2181 increment the value and add it into the environment.
2182 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2183 * NEWS: Mention MAKE_RESTARTS.
2184 * main.c (always_make_set): New variable. Change the -B option to
2185 set this one instead.
2186 (main): When checking makefiles, only set always_make_flag if
2187 always_make_set is set AND the restarts flag is 0. When building
2188 normal targets, set it IFF always_make_set is set.
2189 (main): Avoid infinite recursion with -W, too: only set what-if
2190 files to NEW before we check makefiles if we've never restarted
2191 before. If we have restarted, set what-if files to NEW _after_ we
2193 Fixes Savannah bug #7566:
2195 2005-06-17 Paul D. Smith <psmith@gnu.org>
2197 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2198 in the prerequisites list.
2200 2005-06-12 Paul D. Smith <psmith@gnu.org>
2202 Fix Savannah bug # 1328.
2204 * configure.in: Check for atexit().
2205 * misc.c (close_stdout): Test stdout to see if writes to it have
2206 failed. If so, be sure to exit with a non-0 error code. Based on
2207 code found in gnulib.
2208 * make.h: Prototype.
2209 * main.c (main): Install close_stdout() with atexit().
2211 2005-06-10 Paul D. Smith <psmith@gnu.org>
2213 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2215 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2216 headers; make vmsWaitForChildren() static; extern vmsify().
2217 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2218 Don't create child_execute_job() here (it's in vmsjobs.c).
2219 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2221 2005-06-09 Paul D. Smith <psmith@gnu.org>
2223 * variable.c (push_new_variable_scope): File variables point
2224 directly to the global_setlist variable. So, inserting a new
2225 scope in front of that has no effect on those variables: they
2226 don't go through current_variable_set_list. If we're pushing a
2227 scope and the current scope is global, push it "the other way" so
2228 that the new setlist is in the global_setlist variable, and
2229 next points to a new setlist with the global variable set.
2230 (pop_variable_scope): Properly undo a push with the new
2232 Fixes Savannah bug #11913.
2234 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2236 * job.c (reap_children): Don't die of the command failed but
2237 the dontcare flag is set. Fixes Savannah bug #13216.
2239 * implicit.c (pattern_search): When creating a target from
2240 an implicit rule match, lookup pattern target and set precious
2241 flag in a newly created target. Fixes Savannah bug #13218.
2243 2005-05-13 Paul D. Smith <psmith@gnu.org>
2245 Implement "if... else if... endif" syntax.
2247 * read.c (eval): Push all checks for conditional words ("ifeq",
2248 "else", etc.) down into the conditional_line() function.
2249 (conditional_line): Rework to allow "else if..." clause. New
2250 return value -2 for lines which are not conditionals. The
2251 ignoring flag can now also be 2, which means "already parsed a
2252 true branch". If that value is seen no other branch of this
2253 conditional can be considered true. In the else parsing if there
2254 is extra text after the else, invoke conditional_line()
2255 recursively to see if it's another conditional. If not, it's an
2256 error. If so, raise the conditional value to this level instead
2257 of creating a new conditional nesting level. Special check for
2258 "else" and "endif", which aren't allowed on the "else" line.
2259 * doc/make.texi (Conditional Syntax): Document the new syntax.
2261 2005-05-09 Paul D. Smith <psmith@gnu.org>
2263 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2264 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2265 recurses to the w32 directory, even on non-Windows systems. Use
2266 the method suggested in the automake manual.
2267 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2268 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2270 2005-05-07 Paul D. Smith <psmith@gnu.org>
2272 * main.c (die): If we're dying with a fatal error (not that a
2273 command has failed), write back any leftover tokens before we go.
2275 * job.c (set_child_handler_action_flags): If there are jobs
2276 waiting for the load to go down, set an alarm to go off in 1
2277 second. This allows us to wake up from a potentially long-lasting
2278 read() and start a new job if the load has gone down. Turn it off
2280 (job_noop): Dummy signal handler function.
2281 (new_job): Invoke it with the new semantics.
2283 * docs/make.texi: Document secondary expansion. Various cleanups
2286 2005-05-03 Paul D. Smith <psmith@gnu.org>
2288 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2289 the targets which are to ultimately be made are called "goals";
2290 see the GNU make manual. Also, MAKECMDGOALS, etc.
2292 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2293 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2294 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2296 2005-05-02 Paul D. Smith <psmith@gnu.org>
2298 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2299 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2300 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2301 functions to vmsjobs.c. #include it into jobs.c.
2303 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2304 jobserver tokens. I found that this happens when an exported
2305 recursive variable contains a $(shell ...) function reference: in
2306 this situation we could "forget" to write back a token.
2308 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2309 we have. It's not reliable to depend on the number of children in
2310 our linked list so keep a separate count.
2311 (new_job): Check jobserver_tokens rather than children &&
2312 waiting_jobs. Increment jobserver_tokens when we get one.
2313 (free_child): If jobserver_tokens is 0, internal error. If it's
2314 >1, write a token back to the jobserver pipe (we don't write a
2315 token for the "free" job). Decrement jobserver_tokens.
2317 * main.c: Add variable master_job_slots.
2318 (main): Set it to hold the number of jobs requested if we're the
2319 master process, when using the jobserver.
2320 (die): Sanity checks: first test jobserver_tokens to make sure
2321 this process isn't holding any tokens we didn't write back.
2322 Second, if master_job_slots is set count the tokens left in the
2323 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2325 2005-04-24 Paul D. Smith <psmith@gnu.org>
2327 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2328 with -l# can lose jobserver tokens, because waiting jobs are not
2329 consulted properly when checking for the "free" token.
2331 * job.c (free_child): Count waiting_jobs as having tokens.
2332 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2333 handle jobs waiting for the load to drop.
2335 2005-04-23 Paul D. Smith <psmith@gnu.org>
2337 * main.c (main): Be careful to not core if a variable setting in
2338 the environment doesn't contain an '='. This is illegal but can
2339 happen in broken setups.
2340 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2342 2005-04-12 Paul D. Smith <psmith@gnu.org>
2344 The second expansion feature causes significant slowdown. Timing
2345 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2346 read the makefile before the feature, to 11+s to do the same
2347 operations after the feature. Additionally, memory usage
2348 increased drastically. To fix this I added some intelligence that
2349 avoids the overhead of the second expansion unless it's required.
2351 * dep.h: Add a new boolean field, need_2nd_expansion.
2353 * read.c (eval): When creating the struct dep for the target,
2354 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2355 (record_files): If there's a "%" in a static pattern rule, it gets
2356 converted to "$*" so set need_2nd_expansion to 1.
2358 * file.c (expand_deps): Rework to be more efficient. Only perform
2359 initialize_file_variables(), set_file_variables(), and
2360 variable_expand_for_file() if the need_2nd_expansion is set.
2362 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2363 (pattern_search): Ditto.
2364 * main.c (handle_non_switch_argument): Ditto.
2366 * read.c (read_all_makefiles): Ditto.
2367 (eval_makefile): Ditto.
2369 2005-04-07 Paul D. Smith <psmith@gnu.org>
2371 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2372 * variable.c (sync_Path_environment): Ditto.
2373 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2375 * main.c (main): Define the .FEATURES variable.
2376 * NEWS: Announce .FEATURES.
2377 * doc/make.texi (Special Variables): Document .FEATURES.
2379 * remake.c (check_dep): If a file is .PHONY, update it even if
2380 it's marked intermediate. Fixes Savannah bug #12331.
2382 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2384 * file.c (expand_deps): Factor out the second expansion and
2385 prerequisite line parsing logic from snap_deps().
2387 * file.c (snap_deps): Use expand_deps(). Expand and parse
2388 prerequisites of the .SUFFIXES special target first. Fixes
2389 Savannah bug #12320.
2391 2005-03-13 Paul D. Smith <psmith@gnu.org>
2393 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2396 2005-03-11 Paul D. Smith <psmith@gnu.org>
2398 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2399 available, not undefined (from Earnie Boyd).
2401 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2403 * implicit.c (pattern_search): Mark an intermediate target as
2404 precious if it happened to be a prerequisite of some (other)
2405 target. Fixes Savannah bug #12267.
2407 2005-03-09 Paul D. Smith <psmith@gnu.org>
2409 * read.c (eval_makefile): Add alloca(0).
2410 (eval_buffer): Ditto.
2412 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2414 * main.c (main): Use o_file instead of o_default when defining
2415 the .DEFAULT_TARGET special variable.
2416 * read.c (eval): Use define_variable_global() instead of
2417 define_variable() when setting new value for the .DEFAULT_TARGET
2418 special variable. Fixes Savannah bug #12266.
2420 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2422 * imlicit.c (pattern_search): Mark files for which an implicit
2423 rule has been found as targets. Fixes Savannah bug #12202.
2425 2005-03-04 Paul D. Smith <psmith@gnu.org>
2428 * doc/make.texi (Automatic Variables): Document $|.
2430 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2432 * read.c (record_files): Instead of substituting % with
2433 actual stem value in dependency list replace it with $*.
2434 This fixes stem triple expansion bug.
2436 * implicit.c (pattern_search): Copy stem to a separate
2437 buffer and make it a properly terminated string. Assign
2438 this buffer instead of STEM (which is not terminated) to
2439 f->stem. Instead of substituting % with actual stem value
2440 in dependency list replace it with $*. This fixes stem
2441 triple expansion bug.
2443 2005-03-01 Paul D. Smith <psmith@gnu.org>
2445 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2446 on Windows, as it takes a handle not a pid. Just exit.
2447 Fix from patch #3679, provided by Alessandro Vesely.
2449 * configure.in: Update check for sys_siglist[] from autoconf manual.
2450 * signame.c (strsignal): Update to use the new autoconf macro.
2452 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2454 * read.c (record_files): Add a check for the list of prerequisites
2455 of a static pattern rule being empty. Fixes Savannah bug #12180.
2457 2005-02-28 Paul D. Smith <psmith@gnu.org>
2459 * doc/make.texi (Text Functions): Update docs to allow the end
2460 ordinal for $(wordlist ...) to be 0.
2461 * function.c (func_wordlist): Fail if the start ordinal for
2462 $(wordlist ...) is <1. Matches documentation.
2463 Resolves Savannah support request #103195.
2465 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2466 previously we were stopping when !-q, exactly the opposite. This
2467 has been wrong since version 1.34, in 1994!
2468 (update_file): If we got an error don't break out to run more
2469 double-colon rules: just return immediately.
2470 Fixes Savannah bug #7144.
2472 2005-02-27 Paul D. Smith <psmith@gnu.org>
2474 * misc.c (end_of_token): Make argument const.
2475 * make.h: Update prototype.
2477 * function.c (abspath, func_realpath, func_abspath): Use
2478 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2479 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2480 * read.c (record_files): Ditto.
2481 * variable.c (do_variable_definition): Ditto.
2483 * function.c (func_error): Create a new function $(info ...) that
2484 simply prints the message to stdout with no extras.
2485 (function_table_init): Add new function to the table.
2486 * NEWS: Add $(info ...) reference.
2487 * doc/make.texi (Make Control Functions): Document it.
2489 New feature: if the system supports symbolic links, and the user
2490 provides the -L/--check-symlink-time flag, then use the latest
2491 mtime between the symlink(s) and the target file.
2493 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2494 readlink(). If both are available, define MAKE_SYMLINKS.
2495 * main.c: New variable: check_symlink_flag.
2496 (usage): Add a line for -L/--check-symlink-times to the help string.
2497 (switches): Add -L/--check-symlink-times command line argument.
2498 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2499 print a warning and disable it again.
2500 * make.h: Declare check_symlink_flag.
2501 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2502 if the file is a symlink then check each link in the chain and
2503 choose the NEWEST mtime we find as the mtime for the file. The
2504 newest mtime might be the file itself!
2505 * NEWS: Add information about this new feature.
2506 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2508 Avoid core dumps described in Savannah bug # 12124:
2510 * file.c: New variable snapped_deps remember whether we've run
2512 (snap_deps): Set it.
2513 * filedef.h: Extern it.
2514 * read.c (record_files): Check snapped_deps; if it's set then
2515 we're trying to eval a new target/prerequisite relationship from
2516 within a command script, which we don't support. Fatal.
2518 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2520 Implementation of the .DEFAULT_TARGET special variable.
2522 * read.c (eval): If necessary, update default_target_name when
2524 * read.c (record_files): Update default_target_file if
2525 default_target_name has changed.
2526 * main.c (default_target_name): Define.
2527 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2528 default_target_name is set use default_target_file as a root
2530 * filedef.h (default_target_name): Declare.
2531 * dep.h (free_dep_chain):
2532 * misc.c (free_dep_chain): Change to operate on struct nameseq
2533 and change name to free_ns_chain.
2534 * file.c (snap_deps): Update to use free_ns_chain.
2536 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2538 Implementation of the second expansion in explicit rules,
2539 static pattern rules and implicit rules.
2541 * read.c (eval): Refrain from chopping up rule's dependencies.
2542 Store them in a struct dep as a single dependency line. Remove
2543 the code that implements SySV-style automatic variables.
2545 * read.c (record_files): Adjust the code that handles static
2546 pattern rules to expand all percents instead of only the first
2547 one. Reverse the order in which dependencies are stored so that
2548 when the second expansion reverses them again they appear in
2549 the makefile order (with some exceptions, see comments in
2550 the code). Remove the code that implements SySV-style automatic
2553 * file.c (snap_deps): Implement the second expansion and chopping
2554 of dependency lines for explicit rules.
2556 * implicit.c (struct idep): Define an auxiliary data type to hold
2557 implicit rule's dependencies after stem substitution and
2560 * implicit.c (free_idep_chain): Implement.
2562 * implicit.c (get_next_word): Implement helper function for
2563 parsing implicit rule's dependency lines into words taking
2564 into account variable expansion requests. Used in the stem
2567 * implicit.c (pattern_search): Implement the second expansion
2568 for implicit rules. Also fixes bug #12091.
2570 * commands.h (set_file_variables): Declare.
2571 * commands.c (set_file_variables): Remove static specifier.
2573 * dep.h (free_dep_chain): Declare.
2574 * misc.c (free_dep_chain): Implement.
2576 * variable.h (variable_expand_for_file): Declare.
2577 * expand.c (variable_expand_for_file): Remove static specifier.
2579 * make.h (strip_whitespace): Declare.
2580 * function.c (strip_whitespace): Remove static specifier.
2582 2005-02-26 Paul D. Smith <psmith@gnu.org>
2584 * main.c (main): Check for ferror() when reading makefiles from stdin.
2585 Apparently some shells in Windows don't close pipes properly and
2588 2005-02-24 Jonathan Grant <jg@jguk.org>
2590 * configure.in: Add MinGW configuration options, and extra w32 code
2592 * Makefile.am: Add MinGW configuration options, and extra w32 code
2594 * main.c: Determine correct program string (after last \ without .exe).
2595 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2597 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2598 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2599 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2600 environment support.
2602 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2604 * function.c (func_shell): When initializing error_prefix, check
2605 that reading file name is not null. This fixes long-standing
2606 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2608 2005-02-09 Paul D. Smith <psmith@gnu.org>
2610 * maintMakefile: Update the CVS download URL to simplify them.
2611 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2612 downloading the .texi files from Savannah now.
2614 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2616 * main.c (handle_non_switch_argument): Only add variables to
2617 command_variables if they're not already there: duplicate settings
2618 waste space and can be confusing to read.
2620 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2621 this header is never included by non-WINDOWS32 code, and it
2622 requires <config.h> to define which isn't always included first.
2624 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2625 testing MINGW32 versions.
2627 * main.c (log_working_directory): flush stdout to be sure the WD
2628 change is printed before any stderr messages show up.
2630 2005-02-01 Paul D. Smith <psmith@gnu.org>
2632 * maintMakefile (po_repo): Update the GNU translation site URL.
2634 2004-12-01 Paul D. Smith <psmith@gnu.org>
2636 * main.c (main): Change char* env_shell to struct variable shell_var.
2637 * variable.c (target_environment): Use new shell_var.
2639 2004-11-30 Paul D. Smith <psmith@gnu.org>
2641 * configure.in: The old way we avoided creating build.sh from
2642 build.sh.in before build.sh.in exists doesn't work anymore; we
2643 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2644 the help!). This also keeps automake from complaining.
2645 * Makefile.am (README): Add a dummy target so automake won't
2646 complain that this file doesn't exist when we checkout from CVS.
2647 * maintMakefile (.dep_segment): Rewrite this rule since newer
2648 versions of automake don't provide DEP_FILES.
2650 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2652 Implementation of `realpath' and `abspath' built-in functions.
2654 * configure.in: Check for realpath.
2655 * function.c (abspath): Return an absolute file name that does
2656 not contain any `.' or `..' components, nor repeated `/'.
2657 * function.c (func_abspath): For each name call abspath.
2658 * function.c (func_realpath): For each name call realpath
2659 from libc or delegate to abspath if realpath is not available.
2660 * doc/make.texi (Functions for File Names): Document new functions.
2661 * doc/make.texi (Quick Reference): Ditto.
2663 2004-11-28 Paul D. Smith <psmith@gnu.org>
2665 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2666 arguments. Fixes bug #10252.
2668 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2670 * main.c (main): Set SHELL to v_noexport by default. Remember the
2671 original environment setting of SHELL in the env_shell variable.
2672 * main.h: Export new env_shell variable.
2673 * variable.c (target_environment): If we find a v_noexport
2674 variable for SHELL, add a SHELL variable with the env_shell value.
2675 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2676 * doc/make.texi (Variables/Recursion): Ditto.
2678 2004-11-28 Paul D. Smith <psmith@gnu.org>
2680 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2681 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2682 Patch by Alessandro Vesely.
2684 2004-11-12 Paul D. Smith <psmith@gnu.org>
2686 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2687 the command line if it's inside a string.
2688 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2690 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2692 * function.c (func_lastword): New function: return last word
2693 from the list of words.
2694 * doc/make.texi: Document $(lastword ). Fix broken links in
2695 Quick Reference section.
2697 2004-10-06 Paul D. Smith <psmith@gnu.org>
2699 Apply patch from Alessandro Vesely, provided with bug # 9748.
2700 Fix use of tmpnam() to work with Borland C.
2702 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2703 construction of a temporary filename, and call new function
2704 create_batch_filename().
2705 (create_batch_filename) [WINDOWS32]: New function to create a
2708 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2710 * read.c (record_target_var): Expand simple pattern-specific
2712 * variable.c (initialize_file_variables): Do not expand simple
2713 pattern-specific variable.
2715 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2717 * remake.c (update_file_1): When rebuilding makefiles inherit
2718 dontcare flag from a target that triggered update.
2720 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2722 * variable.c (initialize_file_variables): Mark pattern-specific
2723 variable as a per-target and copy export status.
2725 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2727 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2729 * implicit.c (pattern_search): When considering an implicit rule's
2730 prerequisite check that it is actually a target rather then
2731 just an entry in the file hashtable.
2733 2004-09-21 Paul D. Smith <psmith@gnu.org>
2735 * read.c (readstring): Fix some logic errors in backslash handling.
2736 (eval): Remove some unnecessary processing in buffer handling.
2737 (record_target_var): Assert that parse_variable_definition() succeeded.
2738 Reported by: Markus Mauhart <qwe123@chello.at>.
2740 * misc.c: Removed the sindex() function. All instances of this
2741 function were trivially replaceable by the standard strstr()
2742 function, and that function will always have better (or certainly
2743 no worse) performance than the very simple-minded algorithm
2744 sindex() used. This can matter with complex makefiles.
2745 * make.h: Remove the prototype for sindex().
2746 * function.c (subst_expand): Convert sindex() call to strstr().
2747 This means we no longer need to track the TLEN value so remove that.
2748 (func_findstring): Convert sindex() to strstr().
2749 * commands.c (chop_commands): Convert sindex() calls to strstr().
2750 Suggested by: Markus Mauhart <qwe123@chello.at>.
2752 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2753 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2754 If SHELL is set to CMD.EXE then assume it's batch-mode and
2755 non-unixy. I wrote the code differently from the patch, though,
2756 to make it safer. This also resolves bug #9174.
2758 2004-09-20 Paul D. Smith <psmith@gnu.org>
2760 * expand.c (variable_expand_string): Modify to invoke
2761 patsubst_expand() instead of subst_expand(); the latter didn't
2762 handle suffix patterns correctly.
2763 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2764 was used only from variable_expand_string() and is no longer used
2766 (func_subst): Ditto, on call to subst_expand().
2767 (patsubst_expand): Require the percent pointers to point to the
2768 character after the %, not to the % itself.
2769 * read.c (record_files): New call criteria for patsubst_expand().
2770 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2771 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2773 2004-09-19 Paul D. Smith <psmith@gnu.org>
2775 * function.c (subst_expand): Fix a check in by_word: look for a
2776 previous blank if we're beyond the beginning of the string, not
2777 the beginning of the word.
2778 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2780 2004-05-16 Paul D. Smith <psmith@gnu.org>
2782 * remake.c (update_goal_chain): Change the argument specifying
2783 whether we're rebuilding makefiles to be a global variable,
2784 REBUILDING_MAKEFILES.
2785 (complain): Extract the code that complains about no rules to make
2786 a target into a separate function.
2787 (update_file_1): If we tried to rebuild a file during the makefile
2788 rebuild phase and it was dontcare, then no message was printed.
2789 If we then try to build the same file during the normal build,
2790 print a message this time.
2791 (remake_file): Don't complain about un-remake-able files when
2792 we're rebuilding makefiles.
2794 2004-05-11 Paul D. Smith <psmith@gnu.org>
2796 * job.c (construct_command_argv_internal): OS/2 patches from
2797 Andreas Buening <andreas.buening@nexgo.de>.
2799 2004-05-10 Paul D. Smith <psmith@gnu.org>
2801 * remake.c (update_file): Don't walk the double-colon chain unless
2802 this is a double-colon rule. Fix suggested by Boris Kolpackov
2803 <boris@kolpackov.net>.
2805 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2806 * readme.vms: New section describing OpenVMS support and issues.
2807 * default.c (default_variables): Add support for IA64.
2808 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2809 without some privilege aborts make with the error
2810 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2811 pressing Ctrl+Y and the input device is no terminal. The change
2812 catches this error and just continues.
2814 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2816 2004-04-25 Paul D. Smith <psmith@gnu.org>
2818 * commands.c (set_file_variables): Set $< properly in the face of
2819 order-only prerequisites.
2820 Patch from Boris Kolpackov <boris@kolpackov.net>
2822 2004-04-21 Bob Byrnes <byrnes@curl.com>
2824 * main.c (main): Notice failures to remake makefiles.
2826 2004-03-28 Paul D. Smith <psmith@gnu.org>
2828 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2830 * job.c: No default shell for RISC OS.
2831 (load_too_high): Hard-code the return to 1.
2832 (construct_command_argv_internal): No sh_chars or sh_cmds.
2833 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2835 2004-03-20 Paul D. Smith <psmith@gnu.org>
2837 * variable.c (do_variable_definition): Don't append from the
2838 global set if a previous non-appending target-specific variable
2839 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2842 * expand.c (reference_variable): Don't give up on variables with
2843 no value that have the target-specific append flag set: they might
2844 have a value after all. Reported by Oliver Schmidt
2845 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2846 <nikulin@dx1cmd.inp.nsk.su>.
2848 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2849 refer to absolute pathnames in directories that don't exist: some
2850 portion of the makefile could create those directories before we
2851 match the pattern. Fixes bugs #775 and #108.
2853 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2855 * main.c (main): Free makefile_mtimes if we have any.
2856 * README.W32.template: Update documentation for the current status
2857 of the MS-Windows port.
2858 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2859 environment variable is sometimes already defined which causes the
2861 * main.c (debug_signal_handler): Only define this function if
2862 SIGUSR1 is available.
2864 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2866 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2867 * README.OS2.template: Documentation updates.
2868 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2869 link line for safety.
2870 * maintMakefile (build.sh.in): Remove an extraneous ")".
2871 * job.c (child_execute_job): Close saved FDs.
2872 * job.c (exec_command) [OS/2]: exec_command(): If the command
2873 can't be exec'ed and if the shell is not Unix-sh, then try again
2874 with argv = { "cmd", "/c", ... }. Normally, this code is never
2875 reached for the cmd shell unless the command really doesn't exist.
2876 (construct_command_argv_internal) [OS/2]: The code for cmd
2877 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2878 The CMD builtin commands are case insensitive so use strcasecmp().
2880 2004-03-19 Paul D. Smith <psmith@gnu.org>
2882 * read.c (do_define): Re-order line counter increment so the count
2883 is accurate (we were losing one line per define). Reported by
2884 Dave Yost <Dave@Yost.com>.
2886 2004-03-06 Paul D. Smith <psmith@gnu.org>
2888 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2890 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2891 * misc.c (message,error,fatal): Ditto.
2892 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2893 * config.h.W32.template: Ditto.
2894 * config.h-vms.template: Ditto.
2895 * config.ami.template: Ditto.
2897 2004-03-04 Paul D. Smith <psmith@gnu.org>
2899 * README.template: Add a note about broken /bin/sh on SunOS
2900 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2902 * misc.c (message, error, fatal): Don't use "..." if we're using
2903 varargs. ansi2knr should handle this but it doesn't work: it
2904 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2905 done. On many systems (SunOS for example) va_dcl is a #define.
2906 So, force the use of the non-"..." version on pre-ANSI compilers.
2908 * maintMakefile (sign-dist): Create some rules to help automate
2909 the new GNU ftp upload method.
2911 2004-02-24 Paul D. Smith <psmith@gnu.org>
2913 * config.h.W32.template: Add HAVE_STDARG_H
2914 * config.h-vms.template: Ditto.
2915 * config.ami.template: Ditto.
2917 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2919 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2920 * build_w32.bat: Remove extra "+".
2922 2004-02-23 Paul D. Smith <psmith@gnu.org>
2924 * make.h: Create an UNUSED macro to mark unused parameters.
2925 * (many): Clean up warnings by applying UNUSED, fixing
2926 signed/unsigned incompatibilities, etc.
2928 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2930 * filedef.h: Name the command_state enumeration.
2931 * file.c (set_command_state): Use the enumeration in the function
2934 * configure.in: Explicitly set SET_MAKE to empty, to disable
2935 MAKE=make even when no make already exists. Fix bug #3823.
2937 2004-02-22 Paul D. Smith <psmith@gnu.org>
2939 * maintMakefile: Perl script to clean up all non-CVS files. Use
2940 it on all the subdirectories for the cvs-clean target.
2942 * main.c (decode_switches): Require non-empty strings for all our
2943 string command-line options. Fixes Debian bug # 164165.
2945 * configure.in: Check for stdarg.h and varargs.h.
2946 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2947 for printing messages.
2948 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2953 A number of patches for OS/2 support from Andreas Buening
2954 <andreas.buening@nexgo.de>:
2956 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2957 disable the SIGCHLD handler.
2958 (reap_children) [OS/2]: Remove special handling of job_rfd.
2959 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2960 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2961 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2962 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2963 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2966 2004-02-21 Paul D. Smith <psmith@gnu.org>
2968 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2969 <mail@kristov.de> reports that if process_begin() fails we don't
2970 handle the error condition correctly in all cases.
2971 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2972 to have a newline on the message.
2974 * job.c (construct_command_argv_internal): Add "test" to UNIX
2975 sh_cmds[]. Fixes Savannah bug # 7606.
2977 2004-02-04 Paul D. Smith <psmith@gnu.org>
2979 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2980 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2981 Hartmut Becker <Hartmut.Becker@hp.com>.
2983 2004-01-21 Paul D. Smith <psmith@gnu.org>
2985 * job.c (load_too_high): Implement an algorithm to control the
2986 "thundering herd" problem when using -l to control job creation
2987 via the load average. The system only recomputes the load once a
2988 second but we can start many jobs in a second. To solve this we
2989 keep track of the number of jobs started in the last second and
2990 apply a weight to try to guess what a correct load would be.
2991 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2992 Also fixes bug #4693.
2993 (reap_children): Decrease the job count for this second.
2994 (start_job_command): Increase the job count for this second.
2996 * read.c (conditional_line): Expand the text after ifn?def before
2997 checking to see if it's a single word. Fixes bug #7257.
2999 2004-01-09 Paul D. Smith <psmith@gnu.org>
3001 * file.c (print_file): Recurse to print all targets in
3002 double-colon rules. Fixes bug #4518, reported (with patch) by
3003 Andrew Chatham <chatham@google.com>.
3005 2004-01-07 Paul D. Smith <psmith@gnu.org>
3007 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3008 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3009 AC_FUNC_SETVBUF_REVERSED.
3011 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3012 (MAKE Variable): Fix Savannah bug #4898.
3014 * job.c (construct_command_argv_internal): Add "!" to the list of
3015 shell escape chars. POSIX sh allows it to appear before a
3016 command, to negate the exit code. Fixes bug #6404.
3018 * implicit.c (pattern_search): When matching an implicit rule,
3019 remember which dependencies have the ignore_mtime flag set.
3020 Original fix provided in Savannah patch #2349, by Benoit
3021 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3023 2003-11-22 Paul D. Smith <psmith@gnu.org>
3025 * README.W32.template (Outputs): Clarification on -j with
3026 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3029 2003-11-02 Paul D. Smith <psmith@gnu.org>
3031 * function.c (func_if): Strip all the trailing whitespace from the
3032 condition, then don't expand it. Fixed bug # 5798.
3034 * expand.c (recursively_expand_for_file): If we're expanding a
3035 variable with no file context, then use the variable's context.
3038 2003-10-21 Paul D. Smith <psmith@gnu.org>
3040 * main.c (log_working_directory): Add newlines to printf()s.
3042 * README.cvs: Add a note to ignore warnings during autoreconf.
3044 * maintMakefile (po_repo): Set a new URL for PO file updates.
3045 (get-config/config.guess get-config/config.sub): Get these files
3046 from the Savannah config project instead of ftp.gnu.org.
3048 2003-10-05 Paul Eggert <eggert@twinsun.com>
3050 * main.c (main): Avoid potential subscript error if environ has
3053 2003-08-22 Paul D. Smith <psmith@gnu.org>
3055 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3056 systems which don't yet implement the C89 standard :-/.
3058 2003-07-18 Paul D. Smith <psmith@gnu.org>
3060 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3061 [WINDOWS32]: Initialize hash.
3063 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3065 * dir.c (read_dirstream): Provide a workaround for broken versions of
3066 the MinGW dirent structure.
3068 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3070 * w32/include/dirent.h: Add __MINGW32__ filter.
3072 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3074 * make.h: Add global declaration of *make_host.
3075 * main.c (print_usage): Remove local declaration of *make_host.
3076 (print_version): Display "This program built for ..." after Copyright
3079 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3081 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3082 execution of "makeinfo --html make.texi".
3084 2003-04-30 Paul D. Smith <psmith@gnu.org>
3086 * build.template: Make some changes to maybe allow this script to
3087 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3089 * README.OS2.template: New file for OS/2 support. Original
3090 contributed by Andreas Buening.
3091 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3094 2003-04-19 Paul D. Smith <psmith@gnu.org>
3096 Fix bug #1405: allow a target to match multiple pattern-specific
3099 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3100 variable.c, where they've always belonged.
3101 * rule.h: Move the prototypes and struct pattern_var as well.
3102 * variable.c (initialize_file_variables): Invoke
3103 lookup_pattern_var() in a loop, until no more matches are found.
3104 If a match is found, create a new variable set for the target's
3105 pattern variables. Then merge the contents of each matching
3106 pattern variable set into the target's pattern variable set.
3107 (lookup_pattern_var): Change this function to be usable
3108 in a loop. It takes a starting position: if NULL, start at the
3109 beginning; if non-NULL, start with the pattern variable after that
3110 position, and return the next matching pattern.
3111 (create_pattern_var): Create a unique instance of
3112 pattern-specific variables for every definition in the makefile.
3113 Don't combine the same pattern together. This allows us to
3114 process the variable handling properly even when the same pattern
3115 is used multiple times.
3116 (parse_variable_definition): New function: break out the parsing
3117 of a variable definition line from try_variable_definition.
3118 (try_variable_definition): Call parse_variable_definition to
3120 (print_variable_data_base): Print out pattern-specific variables.
3121 * variable.h (struct variable): Remember when a variable is
3122 conditional. Also remember its flavor.
3123 (struct pattern_var): Instead of keeping a variable set, we just
3124 keep a single variable for each pattern.
3125 * read.c (record_target_var): Each pattern variable contains only a
3126 single variable, not a set, so create it properly.
3127 * doc/make.texi (Pattern-specific): Document the new behavior.
3129 2003-04-17 Paul D. Smith <psmith@gnu.org>
3131 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3132 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3133 file/directory naming rules for VMS so I can't tell whether this
3136 2003-04-09 Paul D. Smith <psmith@gnu.org>
3138 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3139 DOS-style pathnames: backslash separators and drive specifiers.
3141 2003-03-28 Paul D. Smith <psmith@gnu.org>
3143 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3144 the intermediate flag on all targets. Fixes bug #2515.
3146 2003-03-24 Paul D. Smith <psmith@gnu.org>
3148 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3149 Upgrade to autoconf 2.57 and automake 1.7.3.
3151 * job.c: More OS/2 changes from Andreas Buening.
3153 * file.c (print_file): Fix variable initialization.
3156 * remake.c (notice_finished_file):
3158 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3159 some calls (like readdir()) return NULL in valid situations
3160 without resetting errno. Fixes bug #2846.
3162 2003-02-25 Paul D. Smith <psmith@gnu.org>
3164 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3166 * job.c (_is_unixy_shell) [OS/2]: New function.
3167 Set default shell to /bin/sh.
3168 (reap_children): Close the job_rfd pipe here since we don't use a
3170 (set_child_handler_action_flags): define this to empty on OS/2.
3171 (start_job_command): Close the jobserver pipe and use
3172 child_execute_job() instead of fork/exec.
3173 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3174 rather than exec'ing, then reconfigure stdin/stdout.
3175 (exec_command): Rewrite to use spawn instead of exec. Return the
3178 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3179 in DOS. Handle the TEMP environment variable as in DOS. Don't
3180 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3181 use -j in DOS mode. Use child_execute_job() instead of
3184 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3187 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3188 prototypes that return values.
3190 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3192 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3193 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3195 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3198 2003-02-24 Paul D. Smith <psmith@gnu.org>
3200 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3201 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3202 (child_execute_job) [VMS]: Handle error status properly.
3203 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3205 * function.c (func_shell): Use EINTRLOOP() while reading from the
3206 subshell pipe (Fixes bug #2502).
3207 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3209 * main.c (main): Ditto.
3211 2003-01-30 Paul D. Smith <psmith@gnu.org>
3213 * read.c (eval): eval() was not fully reentrant, because the
3214 collapsed buffer was static. Change it to be an automatic
3215 variable so that eval() can be invoked recursively.
3217 (eval): Apply patch # 1022: fix memory reference error on long
3218 target-specific variable lines.
3219 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3221 * function.c (check_numeric): Combine the is_numeric() function
3222 into this function, since it's only called from one place.
3223 Constify this function. Have it print the incorrect string in the
3224 error message. Fixes bug #2407.
3225 (strip_whitespace): Constify.
3226 (func_if): Constify.
3227 * expand.c (expand_argument): Constify.
3229 2003-01-29 Paul D. Smith <psmith@gnu.org>
3231 Fix bug # 2169, also reported by other people on various systems.
3233 * make.h: Some systems, such as Solaris and PTX, do not fully
3234 implement POSIX-compliant SA_RESTART functionality; important
3235 system calls like stat() and readdir() can still fail with EINTR
3236 even if SA_RESTART has been set on the signal handler. So,
3237 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3238 EINTR for system calls which return -1 or 0 (NULL), respectively,
3240 Also, remove the old atomic_stat()/atomic_readdir() and
3241 HAVE_BROKEN_RESTART handling.
3243 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3245 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3246 * remake.c (touch_file): Ditto.
3248 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3249 * read.c (construct_include_path): Ditto.
3250 * remake.c (name_mtime): Ditto.
3251 * vpath.c (selective_vpath_search): Ditto.
3252 * dir.c (find_directory): Ditto.
3253 (local_stat): Ditto.
3254 (find_directory): Use ENULLLOOP() to wrap opendir().
3255 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3257 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3258 atomic_readdir() handling.
3260 2003-01-22 Paul D. Smith <psmith@gnu.org>
3262 * function.c (func_call): Fix Bug #1744. If we're inside a
3263 recursive invocation of $(call ...), mask any of the outer
3264 invocation's arguments that aren't used by this one, so that this
3265 invocation doesn't "inherit" them accidentally.
3267 2002-12-05 Paul D. Smith <psmith@gnu.org>
3269 * function.c (subst_expand): Valery Khamenia reported a
3270 pathological performance hit when doing substitutions on very
3271 large values with lots of words: turns out we were invoking
3272 strlen() a ridiculous number of times. Instead of having each
3273 call to sindex() call strlen() again, keep track of how much of
3274 the text we've seen and pass the length to sindex().
3276 2002-11-19 Paul D. Smith <psmith@gnu.org>
3278 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3281 2002-11-16 Paul D. Smith <psmith@gnu.org>
3283 * NMakefile.template (OBJS): Add hash.c object file.
3284 * SMakefile.template (srcs): Ditto.
3285 * Makefile.ami (objs): Ditto.
3286 * build_w32.bat: Ditto.
3288 * Makefile.DOS.template: Remove extra dependencies.
3290 2002-10-25 Paul D. Smith <psmith@gnu.org>
3292 * expand.c (install_variable_buffer): New function. Install a new
3293 variable_buffer context and return the previous one.
3294 (restore_variable_buffer): New function. Free the current
3295 variable_buffer context and put a previously saved one back.
3296 * variable.h: Prototypes for {install,restore}_variable_buffer.
3297 * function.c (func_eval): Push a new variable_buffer context
3298 before we eval, then restore the old one when we're done.
3301 * read.c (install_conditionals): New function. Install a new
3302 conditional context and return the previous one.
3303 (restore_conditionals): New function. Free the current
3304 conditional context and put a previously saved one back.
3305 (eval): Use the {install,restore}_conditionals for "include"
3307 (eval_buffer): Use {install,restore}_conditionals to preserve the
3308 present conditional state before we evaluate the buffer.
3311 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3313 (Recursion): Add a variable index entry for CURDIR.
3315 * README.cvs: Update to appropriate versions.
3316 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3317 don't need to copy loadavg.c: automake is smart enough to create
3318 it for me. Still have a bug in automake related to ansi2knr tho.
3320 2002-10-14 Paul D. Smith <psmith@gnu.org>
3322 * remake.c (notice_finished_file): Only touch targets if they have
3323 at least one command (as per POSIX). Resolve Bug #1418.
3325 * *.c: Convert to using ANSI C-style function definitions.
3326 * Makefile.am: Enable the ansi2knr feature of automake.
3327 * configure.in: ditto.
3329 2002-10-13 Paul D. Smith <psmith@gnu.org>
3331 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3332 for automatic variable values like $^, etc. In the case of very
3333 large lists of prerequisites this causes problems. Instead reuse
3334 a static buffer (resizeable) for each variable.
3336 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3337 target-specific variable definitions. Check for it and set an
3339 (record_target_var): Set the export field to v_export if the
3340 "exported" flag is set.
3341 * doc/make.texi (Target-specific): Document the ability to use
3344 * doc/make.texi: Change the name of the section on automatic
3345 variables from "Automatic" to "Automatic Variables". Added text
3346 clarifying the scope of automatic variables.
3348 2002-10-04 Paul D. Smith <psmith@gnu.org>
3350 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3352 (record_files): Ditto.
3354 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3355 the search for the '=' to only within the enclosing parens.
3357 2002-10-03 Paul D. Smith <psmith@gnu.org>
3359 Version 3.80 released.
3361 * dir.c: Change hash functions to use K&R function definition style.
3362 * function.c: Ditto.
3364 * variable.c: Ditto.
3366 Update to automake 1.7.
3368 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3369 (pdf): Remove this target as automake now provides one.
3371 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3373 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3375 * makefile.com: Updates for GNU make 3.80.
3376 * makefile.vms: Ditto.
3378 2002-09-23 Paul D. Smith <psmith@gnu.org>
3380 * read.c (enum make_word_type): Remove w_comment.
3381 (get_next_mword): Don't treat comment characters as special; where
3382 this function is used we will never see a comment (it's stripped
3383 before we get here) and treating comments specially means that
3384 targets like "foo\#bar" aren't handled properly.
3386 2002-09-18 Paul D. Smith <psmith@gnu.org>
3388 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3390 * read.c (eval): Expansion of arguments to export/unexport was
3391 ignoring all arguments after the first one. Change the algorithm
3392 to expand the whole line once, then parse the results.
3394 2002-09-17 Paul D. Smith <psmith@gnu.org>
3396 Fix Bug #940 (plus another bug I found while looking at this):
3398 * read.c (record_target_var): enter_file() will add a new entry if
3399 it's a double-colon target: we don't want to do that in this
3400 situation. Invoke lookup_file() and only enter_file() if it does
3401 not already exist. If the file we get back is a double-colon then
3402 add this variable to the "root" double-colon target.
3404 * variable.c (initialize_file_variables): If this file is a
3405 double-colon target but is not the "root" target, then initialize
3406 the root and make the root's variable list the parent of our
3409 2002-09-13 Paul D. Smith <psmith@gnu.org>
3411 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3413 * hash.c (round_up_2): Get rid of a warning.
3415 2002-09-12 Paul D. Smith <psmith@gnu.org>
3417 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3418 so it doesn't complain about getloadavg.c.
3420 * commands.c (set_file_variables): Make sure we always alloca() at
3421 least 1 character for the value of $? (for '\0').
3423 2002-09-11 Paul D. Smith <psmith@gnu.org>
3425 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3426 macro to use RESULT instead of the incorrect _RESULT_.
3428 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3429 and atomic_readdir(). We need to #include dirent.h to get this to
3431 * misc.c (atomic_readdir): Fix typos.
3433 2002-09-10 Paul D. Smith <psmith@gnu.org>
3435 * read.c (eval): Expand variable lists given to export and
3436 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3437 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3439 * doc/make.texi (Variables/Recursion): Document this.
3440 (Conditional Syntax): And here.
3442 2002-09-09 Paul D. Smith <psmith@gnu.org>
3444 * configure.in: Check for memmove().
3446 2002-09-07 Paul D. Smith <psmith@gnu.org>
3448 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3449 Michael Sterrett <msterret@coat.com> reports that while it has
3450 SA_RESTART, it does not work properly.
3452 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3453 that invokes stat() and loops to do it again if it returns EINTR.
3454 (atomic_readdir): Ditto, with readdir().
3456 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3457 and readdir() to atomic_stat() and atomic_readdir().
3459 2002-09-04 Paul D. Smith <psmith@gnu.org>
3461 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3462 reports that GNU make sometimes doesn't recognize that targets can
3463 be made, when directories can be created as prerequisites. He
3464 reports that changing the order of predicates in the DEP->changed
3465 flag test so that lookup_file() is always performed, solves this
3468 2002-08-08 Paul D. Smith <psmith@gnu.org>
3470 * configure.in: Require a newer version of gettext.
3472 * misc.c (perror_with_name): Translate the format string (for
3473 right-to-left language support).
3474 (pfatal_with_name): Ditto.
3476 * main.c: Create a static array of strings to store the usage
3477 text. This is done to facilitate translations.
3478 (struct command_switch): Remove argdesc and description fields.
3479 (switches): Remove values for obsolete fields.
3480 (print_usage): Print each element of the usage array.
3482 * hash.c: Change function definitions to be K&R style.
3484 2002-08-02 Paul D. Smith <psmith@gnu.org>
3486 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3487 this one because it's too hard to get right. We'll look at it for
3489 * main.c (main): Don't create the .TARGETS variable.
3490 * variable.c (handle_special_var): Don't handle .TARGETS.
3492 2002-08-01 Paul D. Smith <psmith@gnu.org>
3494 * main.c (switches): Add a new option, -B (--always-make). If
3495 specified, make will rebuild all targets that it encounters even
3496 if they don't appear to be out of date.
3497 (always_make_flag): New flag.
3498 * make.h: Extern always_make_flag.
3499 * remake.c (update_file_1): Check always_make_flag; if it's set we
3500 will always rebuild any target we can, even if none of its
3501 prerequisites are newer.
3504 * doc/make.texi (Shell Function): Make it clear that make
3505 variables marked as "export" are not passed to instances of the
3508 Add new introspection variable .VARIABLES and .TARGETS.
3510 * variable.c (handle_special_var): New function. If the variable
3511 reference passed in is "special" (.VARIABLES or .TARGETS),
3512 calculate the new value if necessary. .VARIABLES is handled here:
3513 walk through the hash of defined variables and construct a value
3514 which is a list of the names. .TARGETS is handled by
3515 build_target_list().
3516 (lookup_variable): Invoke handle_special_var().
3517 * file.c (build_target_list): Walk through the hask of known files
3518 and construct a list of the names of all the ones marked as
3520 * main.c (main): Initialize them to empty (and as simple variables).
3521 * doc/make.texi (Special Variables): Document them.
3522 * NEWS: Mention them.
3524 * variable.h (struct variable): Add a new flag "exportable" which
3525 is true if the variable name is valid for export.
3526 * variable.c (define_variable_in_set): Set "exportable" when a new
3527 variable is defined.
3528 (target_environment): Use the "exportable" flag instead of
3529 re-checking the name here... an efficiency improvement.
3531 2002-07-31 Paul D. Smith <psmith@gnu.org>
3533 * config.h-vms.template: Updates to build on VMS. Thanks to
3534 Brian_Benning@aksteel.com for helping verify the build.
3535 * makefile.com: Build the new hash.c file.
3536 * hash.h: Use strcpmi(), not stricmp(), in the
3537 HAVE_CASE_INSENSITIVE_FS case.
3539 2002-07-30 Paul D. Smith <psmith@gnu.org>
3541 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3542 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3543 Reported by <Brian_Benning@aksteel.com>.
3545 2002-07-10 Paul D. Smith <psmith@gnu.org>
3547 * variable.c (pop_variable_scope): Remove variable made unused by
3548 new hash infrastructure.
3549 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3550 comparisons as well as name comparisons.

3552 * file.c (lookup_file): Remove variables made unused by new hash
3554 * dir.c (directory_contents_hash_2): Missing return of hash value.
3555 (dir_contents_file_exists_p): Remove variables made unused by new
3556 hash infrastructure.
3559 Installed Greg McGary's integration of the hash functions from the
3560 GNU id-utils package:
3562 2002-07-10 Greg McGary <greg@mcgary.org>
3564 * scripts/functions/filter-out: Add literals to to the
3565 pattern space in order to add complexity, and trigger
3566 use of an internal hash table. Fix documentation strings.
3567 * scripts/targets/INTERMEDIATE: Reverse order of files
3568 passed to expected `rm' command.
3570 2002-07-10 Greg McGary <greg@mcgary.org>

3631 and '%', if present. Note a_word length. Use a hash table if
3632 arglists are large enough to justify cost.
3633 (function_table_init): Renamed from function_table.
3634 (function_table): Declare as `struct hash_table'.
3635 (FUNCTION_TABLE_ENTRIES): New constant.
3636 (hash_init_function_table): New function.
3638 * read.c (hash.h): New #include.
3639 (read_makefile): Pass char constants to find_char_unquote.
3640 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3641 (uniquize_deps): Use hash table to efficiently identify duplicates.
3642 (find_char_unquote): Accept two char-constant stop chars, rather
3643 than a string constant, avoiding zillions of calls to strchr.
3644 Tighten inner search loops to test only for desired delimiters.
3646 * variable.c (variable_hash_1, variable_hash_2,
3647 variable_hash_cmp): New functions.
3648 (variable_table): Declare as `struct hash_table'.
3649 (global_variable_set): Remove initialization.
3650 (init_hash_global_variable_set): New function.
3651 (define_variable_in_set): Use new hash table package.
3652 (lookup_variable): Likewise.
3653 (lookup_variable_in_set): Likewise.
3654 (initialize_file_variables): Likewise.
3655 (pop_variable_scope): Likewise.
3656 (create_new_variable_set): Likewise.
3657 (merge_variable_sets): Likewise.
3658 (define_automatic_variables): Likewise.
3659 (target_environment): Likewise.
3660 (print_variable_set): Likewise.
3662 2002-07-10 Paul D. Smith <psmith@gnu.org>
3664 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3665 prerequisite list. A real SysV make will expand the entire
3666 prerequisites list _twice_: we don't do that as it's a big
3667 backward-compatibility problem. We only replace those specific
3670 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3671 references left in the list of prerequisites. Check for .POSIX as
3672 we record targets, so we can disable non-POSIX behavior while
3673 reading makefiles as well as running them.
3674 (eval): Check the prerequisite list to see if we have anything
3675 that looks like a SysV prerequisite variable reference.
3677 2002-07-09 Paul D. Smith <psmith@gnu.org>
3679 * doc/make.texi (Prerequisite Types): Add a new section describing
3680 order-only prerequisites.
3682 * read.c (uniquize_deps): If we have the same file as both a
3683 normal and order-only prereq, get rid of the order-only prereq,
3684 since the normal one supersedes it.
3686 2002-07-08 Paul D. Smith <psmith@gnu.org>
3688 * AUTHORS: Added Greg McGary to the AUTHORS file.
3689 * NEWS: Blurbed order-only prerequisites.
3690 * file.c (print_file): Show order-only deps properly when printing
3693 * maintMakefile: Add "update" targets for wget'ing the latest
3694 versions of various external files. Taken from Makefile.maint in
3697 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3698 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3700 2002-07-07 Paul D. Smith <psmith@gnu.org>
3702 * po/*.po: Remove. We'll use wget to retrieve them at release
3705 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3706 rather than a shell you get an exception. Make sure we look up
3707 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3709 * remake.c (notice_finished_file): Fix handling of -t flag.
3710 Patch provided by Henning Makholm <henning@makholm.net>.
3712 * implicit.c (pattern_search): Some systems apparently run short
3713 of stack space, and using alloca() in this function caused an
3714 overrun. I modified it to use xmalloc() on the two variables
3715 which seemed like they might get large. Fixes Bug #476.
3717 * main.c (print_version): Update copyright notice to conform with
3719 (print_usage): Update help output.
3721 * function.c (func_eval): Create a new make function, $(eval
3722 ...). Expand the arguments, put them into a buffer, then invoke
3723 eval_buffer() on the resulting string.
3724 (func_quote): Create a new function, $(quote VARNAME). Inserts
3725 the value of the variable VARNAME without expanding it any
3728 * read.c (struct ebuffer): Change the linebuffer structure to an
3729 "eval buffer", which can be either a file or a buffer.
3730 (eval_makefile): Move the code in the old read_makefile() which
3731 located a makefile into here: create a struct ebuffer with that
3732 information. Have it invoke the new function eval() with that
3734 (eval_buffer): Create a new function that creates a struct ebuffer
3735 that holds a string buffer instead of a file. Have it invoke
3736 eval() with that ebuffer.
3737 (eval): New function that contains the guts of the old
3738 read_makefile() function: this function parses makefiles. Obtains
3739 data to parse from the provided ebuffer. Some modifications to
3740 make the flow of the function cleaner and clearer. Still could
3741 use some work here...
3742 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3743 contents of the define/endef variable from the ebuffer.
3744 (readstring): Read the next line from a string-style ebuffer.
3745 (readline): Read the next line from an ebuffer. If it's a string
3746 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3749 * dep.h (eval_buffer): Prototype eval_buffer();
3751 * variable.c (do_variable_definition): Make sure that all
3752 non-target-specific variables are registered in the global set.
3753 If we're invoked from an $(eval ...) we might be inside a $(call
3754 ...) or other function which has pushed a variable scope; we still
3755 want to define our variables from evaluated makefile code in the
3758 2002-07-03 Greg McGary <greg@mcgary.org>
3760 * dep.h (struct dep) [ignore_mtime]: New member.
3761 [changed]: convert to a bitfield.
3762 * implicit.c (pattern_search): Zero ignore_mtime.
3763 * main.c (main, handle_non_switch_argument): Likewise.
3764 * rule.c (convert_suffix_rule): Likewise.
3765 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3766 (read_makefile): Parse '|' in prerequisite list.
3767 (uniquize_deps): Consider ignore_mtime when comparing deps.
3768 * remake.c (update_file_1, check_dep): Don't force remake for
3769 dependencies that have d->ignore_mtime.
3770 * commands.c (FILE_LIST_SEPARATOR): New constant.
3771 (set_file_variables): Don't include a
3772 prerequisite in $+, $^ or $? if d->ignore_mtime.
3775 2002-06-18 Paul D. Smith <psmith@gnu.org>
3777 * make.texinfo: Updates for next revision. New date/rev/etc.
3778 Recreate all Info menus. Change license on the manual to the GNU
3779 Free Documentation License. A number of typos.
3780 (Variables Simplify): Don't use "-" before it's defined.
3781 (Automatic Prerequisites): Rewrite the target example to work
3782 properly if the compile fails. Remove incorrect comments about
3783 how "set -e" behaves.
3784 (Text Functions): Move the "word", "wordlist", "words", and
3785 "firstword" functions here, from "File Name Functions".
3786 * make-stds.texi: Update from latest GNU version.
3787 * fdl.texi: (created) Import the latest GNU version.
3789 2002-06-06 Paul D. Smith <psmith@gnu.org>
3791 * variable.c (do_variable_definition): New function: extract the
3792 part of try_variable_definition() that actually sets the value
3793 into a separate function.
3794 (try_variable_definition): Call do_variable_definition() after
3795 parsing the variable definition string.
3796 (define_variable_in_set): Make the name argument const.
3798 * variable.h (enum variable_flavor): Make public.
3799 (do_variable_definition): Create prototype.
3801 * read.c (read_all_makefiles): Create a new built-in variable,
3803 (read_makefile): Add each makefile read in to this variable value.
3805 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3807 * Makefile.DOS.template: Tweak according to changes in the
3808 distribution. Add back the dependencies of *.o files.
3810 * configh.dos.template: Synchronize with config.h.in.
3812 2002-05-09 Paul D. Smith <psmith@gnu.org>
3814 * file.c (file_timestamp_now): Use K&R function declaration.
3816 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3817 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3818 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3819 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3820 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3821 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3822 nlist.n_name is a pointer rather than an array.
3824 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3825 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3826 * configure.in: Use it instead of the old version.
3828 * main.c (main): Prefer setvbuf() to setlinebuf().
3830 2002-05-08 Paul D. Smith <psmith@gnu.org>
3832 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3833 (loadavg_LDADD): Ditto.
3835 2002-04-29 Paul D. Smith <psmith@gnu.org>
3837 * expand.c (recursively_expand_for_file): Rename
3838 recursively_expand() to recursively_expand_for_file() and provide
3839 an extra argument, struct file. If the argument is provided, set
3840 the variable scope to that of the file before expanding.
3841 * variable.h (recursively_expand): Make this a macro that invokes
3842 recursively_expand_for_file() with a NULL file pointer.
3843 * variable.c (target_environment): Call the renamed function and
3844 provide the current file context.
3845 Fixes Debian bug #144306.
3847 2002-04-28 Paul D. Smith <psmith@gnu.org>
3849 Allow $(call ...) user-defined variables to be self-referencing
3850 without throwing an error. Allows implementation of transitive
3851 closures, among other possibly useful things.
3852 Requested by: Philip Guenther <guenther@sendmail.com>
3854 * variable.h (struct variable): Add a new field: exp_count, and
3855 new macros to hold its size and maximum value.
3856 (warn_undefined): Make this a macro.
3857 * variable.c (define_variable_in_set): Initialize it.
3858 * expand.c (recursively_expand): If we detect recursive expansion
3859 of a variable, check the exp_count field. If it's greater than 0
3860 allow the recursion and decrement the count.
3861 (warn_undefined): Remove this (now a macro in variable.h).
3862 * function.c (func_call): Before we expand the user-defined
3863 function, modify its exp_count field to contain the maximum
3864 number of recursive calls we'll allow. After the call, reset it
3867 2002-04-21 Paul D. Smith <psmith@gnu.org>
3869 Modified to use latest autoconf (2.53), automake (1.6.1), and
3870 gettext (0.11.1). We're using gettext's new "external" support,
3871 to avoid including libintl source with GNU make.
3873 * README.cvs: New file. Explain how to build GNU make from CVS.
3875 * configure.in: Modify checking for the system glob library.
3876 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3877 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3878 etc. will manage it correctly). Set an automake conditional
3879 USE_LOCAL_GLOB to decide whether to compile the glob library.
3881 * getloadavg.c (main): Include make.h in the "TEST" program to
3884 * Makefile.am: Remove special rules for loadavg. Replace them
3885 with Automake capabilities for building extra programs.
3887 * signame.c: This file does nothing if the system provide
3888 strsignal(). If not, it implements strsignal(). If the system
3889 doesn't define sys_siglist, then we make our own; otherwise we use
3891 * signame.h: Removed.
3893 * main.c (main): No need to invoke signame_init(). Update copyright.
3895 * ABOUT-NLS: Removed.
3896 * gettext.c: Removed.
3897 * gettext.h: Get a simplified copy from the gettext package.
3899 * i18n/*.po: Moved to po/.
3902 * config/*: Created. Contains package configuration helper files.
3903 * config.guess, config.sub: Moved to config directory.
3905 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3906 Rework to use new-style autoconf features. Use the "external"
3907 mode for gettext. Make the build.sh config file conditional on
3908 whether build.sh.in exists, to avoid autoconf errors.
3909 * acinclude.m4: Removed almost all macros as being obsolete.
3910 Rewrote remaining macros to use AC_DEFINE.
3911 * acconfig.h: Removed.
3913 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3914 conditional to handle customs support. Remove special handling
3917 2002-04-20 Paul D. Smith <psmith@gnu.org>
3919 * function.c (func_call): Don't mark the argument variables $1,
3920 etc. as recursive. They've already been fully expanded so
3921 there's no need to do it again, and doing so strips escaped $'s.
3922 Reported by Sebastian Glita <glseba@yahoo.com>.
3924 * remake.c (notice_finished_file): Walk through double-colon
3925 entries via the prev field, not the next field!
3926 Reported by Greg McGary <greg@mcgary.org>.
3928 * main.c (main): If the user specifies -q and asks for a specific
3929 target which is a makefile, we got an assert. In that case it
3930 turns out we should continue normally instead.
3932 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3934 * i18n/he.po: Installed a new translation.
3936 2002-01-07 Paul D. Smith <psmith@gnu.org>
3938 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3940 2001-12-04 Paul D. Smith <psmith@gnu.org>
3942 * i18n/ja.po: Installed an updated translation.
3944 2001-09-06 Paul Eggert <eggert@twinsun.com>
3946 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3947 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3949 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3951 (main): Get rid of any avoidable limit on stack size.
3953 2001-09-04 Paul D. Smith <psmith@gnu.org>
3955 * i18n/da.po: Installed an updated translation.
3957 2001-08-03 Paul D. Smith <psmith@gnu.org>
3959 * i18n/fr.po: Installed an updated translation.
3960 Resolves Debian bug #106720.
3962 2001-06-13 Paul D. Smith <psmith@gnu.org>
3964 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3967 2001-06-11 Paul D. Smith <psmith@gnu.org>
3969 * i18n/ko.po: Installed a new translation.
3971 2001-05-06 Paul D. Smith <psmith@gnu.org>
3973 Modify the EINTR handling.
3975 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3976 the way in which we manage the file descriptor/signal handler race
3977 trap to be more efficient.
3979 2001-05-06 Paul Eggert <eggert@twinsun.com>
3981 Restart almost all system calls that are interrupted, instead
3982 of worrying about EINTR. The lone exception is the read() for
3985 * configure.in (HAVE_SA_RESTART): New macro.
3986 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3987 * main.c (main): Use SA_RESTART instead of the old,
3988 nonstandard SA_INTERRUPT.
3990 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3991 * main.c (bsd_signal): New function or macro,
3992 if the implementation doesn't supply it.
3993 (The bsd_signal function will be in POSIX 1003.1-200x.)
3994 (HANDLESIG): Remove.
3995 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3997 * make.h (EINTR_SET): Remove.
3998 (SA_RESTART): New macro.
4000 * arscan.c (ar_member_touch): Don't worry about EINTR.
4001 * function.c (func_shell): Likewise.
4002 * job.c (reap_children, free_child, new_job): Likewise.
4003 * main.c (main): Likewise.
4004 * remake.c (touch_file, name_mtime): Likewise.
4006 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4007 if fstat failed with errno!=EINTR, the error was ignored.
4009 * job.c (set_child_handler_action_flags): New function.
4010 (new_job): Use it to temporarily clear the SIGCHLD action flags
4011 while reading the token.
4013 2001-05-02 Paul D. Smith <psmith@gnu.org>
4015 * job.c (start_job_command): Don't add define/endef per-line flags
4016 to the top-level flags setting.
4018 2001-04-03 Paul D. Smith <psmith@gnu.org>
4020 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4021 bit on error, so check for odd return values, not non-0 return
4023 (VMS_get_member_info): Calculate the timezone differences correctly.
4024 Reported by John Fowler <jfowler@nyx.net>.
4027 2001-03-14 Paul D. Smith <psmith@gnu.org>
4029 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4030 value before invoking define_variable().
4031 Reported by John Fowler <jfowler@nyx.net>.
4033 2001-02-07 Paul D. Smith <psmith@gnu.org>
4035 * read.c (record_target_var): If we reset the variable due to a
4036 command-line variable setting overriding it, turn off the "append"
4039 2001-01-17 Paul D. Smith <psmith@gnu.org>
4041 * variable.c (lookup_variable) [VMS]: When getting values from the
4042 environment, allocate enough space for the _value_ plus escapes,
4043 not enough space for the name plus escapes :-/.
4044 Reported by John Fowler <jfowler@nyx.net>.
4046 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4047 warnings that make generates, so it doesn't look like an error.
4048 Reported by Karl Berry <karl@gnu.org>.
4051 Fix for PR/2020: Rework appended target-specific variables. I'm
4052 fairly confident this algorithm is finally correct.
4054 * expand.c (allocated_variable_append): Rewrite. Instead of
4055 expanding each appended variable then adding all the expanded
4056 strings together, we append all the unexpanded values going up
4057 through the variable set contexts, then expand the final result.
4058 This behaves just like non-target-specific appended variable
4059 values, while the old way didn't in various corner cases.
4060 (variable_append): New function: recursively append the unexpanded
4061 value of a variable, walking from the outermost variable scope to
4063 * variable.c (lookup_variable): Remove the code that looked up the
4064 variable set list if the found variable was "append". We don't
4066 (lookup_variable_in_set): Make this non-static so we can use it
4068 (try_variable_definition): Use lookup_variable_in_set() rather
4069 than faking out current_variable_set_list by hand (cleanup).
4070 * variable.h: Add a prototype for the now non-static
4071 lookup_variable_in_set().
4073 2000-11-17 Paul D. Smith <psmith@gnu.org>
4075 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4076 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4077 before throwing a fit.
4079 2000-11-17 Paul D. Smith <psmith@gnu.org>
4081 * read.c (readline): CRLF calculations had a hole, if you hit the
4082 buffer grow scenario just right. Reworked the algorithm to avoid
4083 the need for len or lastlen at all. Problem description with
4084 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4086 2000-10-24 Paul D. Smith <psmith@gnu.org>
4088 * gettext.c (SWAP): Declare this with the prototype, otherwise
4089 some systems don't work (non-32-bit? Reported for Cray T3E).
4090 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4092 2000-10-05 Paul D. Smith <psmith@gnu.org>
4094 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4095 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4097 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4099 2000-09-22 Paul D. Smith <psmith@gnu.org>
4101 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4102 parts of the real gettext.h here, and we expect to really include
4103 the real gettext.h later. If we keep this #define, it's ignored.
4105 2000-09-21 Paul D. Smith <psmith@gnu.org>
4107 * main.c (log_working_directory): Rework the text to use complete
4108 sentences, to make life simpler for the translators.
4110 2000-08-29 Paul D. Smith <psmith@gnu.org>
4112 * file.c (remove_intermediates): Print a debug message before we
4113 remove intermediate files, so the user (if she uses -d) knows
4116 2000-08-21 Paul D. Smith <psmith@gnu.org>
4118 * variable.c (try_variable_definition): Change how we handle
4119 target-specific append variable defns: instead of just setting the
4120 value, expand it as an append _but_ only within the current
4121 target's context. Otherwise we lose all but the last value if the
4122 variable is appended more than once within the current target
4123 context. Fixes PR/1831.
4125 2000-08-16 Paul D. Smith <psmith@gnu.org>
4127 * function.c (func_shell): Nul-terminate the buffer before
4128 printing an exec error message (just in case it's not!).
4129 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4131 2000-07-25 Paul D. Smith <psmith@gnu.org>
4133 * job.c (construct_command_argv_internal): Add "~" to the list of
4134 sh_chars[] which disallow optimizing out the shell call.
4136 2000-07-23 Paul Eggert <eggert@twinsun.com>
4138 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4139 supersedes --disable-nsec-timestamps.
4140 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4141 * README: Remove --disable-nsec-timestamps.
4143 * filedef.h (struct file.low_resolution_time): New member.
4144 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4145 * remake.c (update_file_1):
4146 Avoid spurious rebuilds due to low resolution time stamps,
4147 generalizing the earlier code that applied only to archive members.
4148 (f_mtime): Archive members always have low resolution time stamps.
4150 * configure.in: Remove --disable-nsec-timestamps, as this has
4151 been superseded by .LOW_RESOLUTION_TIME.
4153 2000-07-23 Paul Eggert <eggert@twinsun.com>
4155 * configure.in (enable_nsec_timestamps): Renamed from
4156 make_cv_nsec_timestamps, since enable/disable options
4157 shouldn't be cached.
4159 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4160 and Paul Eggert <eggert@twinsun.com>
4162 * file.c (file_timestamp_now):
4163 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4164 so that clock_gettime is not linked unless needed.
4166 * filedef.h (FILE_TIMESTAMP_HI_RES):
4167 Remove definition; "configure" now does this.
4169 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4170 to before high resolution file timestamp check,
4171 since that check now uses uintmax_t.
4172 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4173 high resolution file timestamps.
4174 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4175 so that we don't link in clock_gettime unnecessarily.
4177 2000-07-17 Paul D. Smith <psmith@gnu.org>
4179 * i18n/ja.po: New version of the translation file.
4181 2000-07-07 Paul D. Smith <psmith@gnu.org>
4183 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4184 the offset calculation.
4185 (name_mtime): Replace EINTR test with EINTR_SET macro.
4187 2000-07-07 Paul Eggert <eggert@twinsun.com>
4191 * remake.c (update_file_1):
4192 Avoid spurious rebuilds of archive members due to their
4193 timestamp resolution being only one second.
4194 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4195 the clock's resolution being lower than file timestamps'.
4196 When warning about future timestamps, report only the discrepancy,
4197 not the absolute value of the timestamp and the current time.
4199 * file.c (file_timestamp_now): New arg RESOLUTION.
4200 * filedef.h (file_timestamp_now): Likewise.
4201 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4203 2000-07-05 Paul D. Smith <psmith@gnu.org>
4205 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4206 to listp. Fixes PR/1793.
4208 2000-06-26 Paul Eggert <eggert@twinsun.com>
4210 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4212 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4214 * remake.c (f_mtime): Remove unused var memtime.
4216 2000-06-25 Martin Buchholz <martin@xemacs.org>
4218 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4219 Ran spell-check on make.texinfo.
4221 2000-06-23 Paul D. Smith <psmith@gnu.org>
4223 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4224 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4225 * make.h: Define these macros.
4227 * Version 3.79.1 released.
4229 * configure.in: Add a new option, --disable-nsec-timestamps, to
4230 avoid using sub-second timestamps on systems that support it. It
4231 can lead to problems, e.g. if your makefile relies on "cp -p".
4232 * README.template: Document the issue with "cp -p".
4234 * config.guess, config.sub: Updated.
