5 as well. See Savannah bug #32511.
7 2011-09-16 Paul Smith <psmith@gnu.org>

30 2011-08-29 Paul Smith <psmith@gnu.org>
32 * expand.c (variable_expand_string): Always allocate a new buffer
33 for a string we're expanding. The string we're working on can get

99 * read.c (get_next_mword): Treat "!=" as a varassign word.
100 * function.c (fold_newlines): If trim_newlines is set remove all
101 trailing newlines; otherwise remove only the last newline.

105 2011-02-21 Paul Smith <psmith@gnu.org>
107 * strcache.c (various): Increase performance based on comments
108 from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>. Stop looking for
109 a buffer when we find the first one that fits, not the best fit.
110 If there is not enough free space in a buffer move it to a
111 separate list so we don't have to walk it again.

548 Requested by David Boyce <dsb@boyski.com>.
550 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
552 * dep.h (dep): Add the DONTCARE bitfield.
554 * filedef.h (file):Add the NO_DIAG bitfield.
556 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
557 not struct file (a file can be a dependency of many targets,
558 some don't care, some do).
560 * remake.c (update_goal_chain): Propagate DONTCARE from struct
561 dep to struct file before updating the goal and restore it
563 (update_file): Don't prune the dependency graph if this target
564 has failed but the diagnostics hasn't been issued.
565 (complain): Scan the file's dependency graph to find the file
566 that caused the failure.
567 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
568 whether to print diagnostics.
570 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
572 2009-09-28 Paul Smith <psmith@gnu.org>
574 * doc/make.texi (Pattern Intro): Move the match algorithm
575 discussion into the "Pattern Match" node.
576 (Pattern Match): Expand on the pattern rule matching algorithm.
578 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
580 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
581 much of the command line on a single pass.
583 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
585 * varible.c (create_pattern_var): Insert variables into the
586 PATTERN_VARS list in the shortest patterns first order.
588 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
589 used to sort the rules.
590 (stemlen_compare): Compare two tryrule elements.
591 (pattern_search): Sort the rules so that they are in the shortest
594 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
596 * doc/make.texi (Pattern-specific Variable Values): Describe the
597 new pattern-specific variables application order.
598 (Introduction to Pattern Rules): Describe the new pattern rules
601 * NEWS: Add a note about the new behavior.
603 2009-09-27 Paul Smith <psmith@gnu.org>
605 * doc/make.texi (Double-Colon): Mention that pattern rules with
606 double-colons have a different meaning. Savannah bug #27497.
608 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
610 * configh.dos.template: Remove unconditional definition of
611 SYS_SIGLIST_DECLARED.
612 Include <sys/version.h> because ports of GCC 4.3.0 and later no
613 longer include it, so macros like __DJGPP_MINOR__ are no longer
614 defined automatically.
616 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
617 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
618 instead of using the hardcoded ones.
619 (SUBDIRS): doc subdir added.
620 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
621 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
622 create html formated docs. texi2html may not be ported to DOS.
623 (make.info, make.dvi, make.ps, make.html): Make targets depend on
625 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
626 -I switch to look in ./ instead of ./doc.
627 (html): Target depend on html-recursive instead of make_1.html.
628 (make_1.html): Removed.
629 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
630 (all-recursive): Allow for more than one subdir in the build
632 (mostlyclean-recursive, clean-recursive, distclean-recursive)
633 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
634 (tags-recursive): Allow for more than one subdir in the build
636 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
637 targets. Enter into doc/ to produce the targets.
638 (all-am): $(INFO_DEPS) replaced by info.
640 2009-09-26 Paul Smith <psmith@gnu.org>
642 * read.c (record_files): Use free_ns() to free struct nameseq.
645 * rule.c (freerule): Use free_dep_chain().
647 * read.c (record_files): Free FILENAMES chain for implicit rules.
648 (eval): Static pattern targets go into the string cache.
650 * function.c (string_glob): Free NAME in the nameseq chain.
652 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
654 * implicit.c (pattern_search): Terminate early if we haven't
655 found any rules to try (performance improvement).
657 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
659 * implicit.c (pattern_search): Merge three parallel arrays,
660 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
661 of struct TRYRULE. In the old version the latter two arrays
662 had insufficient length.
664 2009-09-24 Paul Smith <psmith@gnu.org>
666 * implicit.c (pattern_search): Add back support for order-only
667 prerequisites for secondary expansion implicit rules, that were
668 accidentally dropped. If we find a "|", enable order-only mode
669 and set IGNORE_MTIME on all deps that are seen afterward.
670 (pattern_search): Fix memory leaks: for intermediate files where
671 we've already set the file variable and pattern variable sets, be
672 sure to either save or free them as appropriate.
674 2009-09-23 Paul Smith <psmith@gnu.org>
676 Rework the way secondary expansion is stored, for efficiency.
677 This changes secondary expansion so that ONLY WHEN we know we have
678 a possibility of needing secondary expansion, do we defer the
679 secondary expansion. This means more parsing the deps but we use
680 a lot less memory (due to the strcache). Also, this fixes
683 * read.c (eval): Don't parse the dep string here anymore.
684 (record_files): Take the dep argument as an unparsed string. If
685 secondary expansion is enabled AND the prereq string has a '$' in
686 it, then set NEED_2ND_EXPANSION and keep the entire string.
687 Otherwise, parse the dep string here to construct the dep list
688 with the names in the strcache.
690 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
691 duplicate the name string (others are in the strcache).
693 * implicit.c: Remove struct idep and free_idep_chain(): unused.
694 (struct patdeps): New structure to store prereq information.
695 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
696 which prerequisites need expansion, and expand only those.
698 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
699 and enter_prereqs(). split_prereqs() takes a fully-expanded string
700 and splits it into a DEP list, handling order-only prereqs.
701 (enter_prereqs): This function enters a list of DEPs into the file
702 database. If there's a stem defined, expand any pattern chars.
703 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
704 set. Use the above functions.
705 (snap_deps): Only perform second expansion on prereqs that need it,
706 as defined by the NEED_2ND_EXPANSION flag.
707 (print_prereqs): New function to print the prereqs
708 (print_file): Call print_prereqs() rather than print inline.
710 * hash.h (STRING_COMPARE): Take advantage of strcache() by
712 (STRING_N_COMPARE): Ditto.
713 (ISTRING_COMPARE): Ditto.
715 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
716 (parse_file_seq): Return void*
717 * read.c (parse_file_seq): Return void*.
718 (eval): Invoke macroized version of parse_file_seq()
719 * default.c (set_default_suffixes): Ditto.
720 * file.c (split_prereqs): Ditto.
721 * function.c (string_glob): Ditto.
722 * main.c (main): Ditto.
723 * rule.c (install_pattern_rule): Ditto.
725 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
727 2009-09-16 Paul Smith <psmith@gnu.org>
729 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
731 * dep.h: Create alloc_dep() / free_dep() macros.
733 * implicit.c (pattern_search): Take advantage of the new
734 parse_file_seq() to add the directory prefix to each prereq.
736 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
737 all. Avoid reversing chains. Support adding prefixes.
738 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
739 cached/non-cached results.
740 (eval): Remove multi_glob() & invoke new parse_file_seq().
741 * rule.c (install_pattern_rule): Ditto.
742 * main.c (main): Ditto.
743 * implicit.c (pattern_search): Ditto.
744 * function.c (string_glob): Ditto.
745 * file.c (parse_prereqs): Ditto.
746 * default.c (set_default_suffixes): Ditto.
748 * variable.c (parse_variable_definition): Don't run off the end of
749 the string if it ends in whitespace (found with valgrind).
751 * commands.c (set_file_variables): Keep space for all targets in
752 $? if -B is given (found with valgrind).
754 2009-09-15 Paul Smith <psmith@gnu.org>
756 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
757 (xcalloc): Add new function.
758 * make.h: New declarations.
760 * ar.c (ar_glob_match): New calling method for concat().
761 * main.c (main): Ditto.
762 (decode_env_switches): Ditto.
763 * read.c (eval_makefile): Ditto.
764 (tilde_expand): Ditto.
765 (parse_file_seq): Ditto.
766 * variable.c (target_environment): Ditto.
767 (sync_Path_environment): Ditto.
769 * ar.c (ar_glob_match): Use xcalloc().
770 * dir.c (file_impossible): Ditto.
771 * file.c (enter_file): Ditto.
772 * job.c (new_job): Ditto.
773 * read.c (parse_file_seq): Ditto.
774 * vmsfunctions.c (opendir): Ditto.
776 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
778 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
779 inside the loop that looks up environment for PATH.
781 2009-08-31 Eli Zaretskii <eliz@gnu.org>
783 * function.c (windows32_openpipe): Update envp after calling
784 sync_Path_environment.
786 2009-08-02 Paul Smith <psmith@gnu.org>
788 * remake.c (notice_finished_file): Ensure file->cmds is not null
789 before looping through them. Fixes Savannah bug #21824.
791 * doc/make.texi (Wildcard Examples): Clarify when objects is
792 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
793 (Include): Clarify the behavior of -include.
794 Fixes Savannah bug #18963.
796 2009-08-01 Paul Smith <psmith@gnu.org>
798 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
799 etc. come on the command line. Fixes Savannah bug #27093.
801 * expand.c (expand_argument): If the argument is large enough use
802 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
804 * variable.c (do_variable_definition): Avoid using alloca() to
805 hold values, which can be large. Fixes Savannah bug #23960.
807 * job.c (new_job): Use memmove() instead of strcpy() since both
808 pointers are in the same memory block. Fixes Savannah bug #27148.
809 Patch by Petr Machata.
811 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
813 * job.c (construct_command_argv_internal): Add "ulimit" and
814 "unset" to the sh_cmds for Unixy shells.
816 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
818 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
819 that set make_cv_sys_gnu_glob, so they are also correctly set
820 when the cache has been populated before.
822 2009-07-04 Eli Zaretskii <eliz@gnu.org>
824 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
825 exist, as realpath(3) does where it's supported.
827 2006-07-04 Eli Zaretskii <eliz@gnu.org>
829 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
830 (abspath): Support systems that define HAVE_DOS_PATHS (have
831 drive letters in their file names). Use IS_PATHSEP instead of a
832 literal '/' comparison. Fixes Savannah bug #26886.
834 2009-06-14 Paul Smith <psmith@gnu.org>
836 * remake.c (update_file_1): Remember the original file we marked
837 as updating, so we can clear that flag again. If we find a target
838 via vpath, FILE might change.
839 (check_dep): Ditto. Fixes Savannah bug #13529.
840 Patch by Reid Madsen <reid.madsen@tek.com>.
842 2009-06-13 Paul Smith <psmith@gnu.org>
844 * doc/make.texi (MAKEFILES Variable): Be explicit that files
845 included by MAKEFILES cannot give default goals.
846 * read.c (eval): If set_default is not set, pass the no-default-goal
847 value when we read included makefiles. Fixes Savannah bug #13401.
849 * ar.c (ar_name): Ensure that targets with empty parens aren't
850 considered archive member references: archive members must have a
851 non-empty "member" string. Fixes Savannah bug #18435.
853 * function.c (string_glob): Rely on multi_glob() to determine
854 whether files exist or not. Remove call to file_exists_p() which
855 is not always correct. Fixes Savannah bug #21231.
856 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
857 then only files that really exist will be returned.
858 * dep.h: Add new argument to multi_glob().
859 * rule.c (install_pattern_rule): Ditto.
860 * read.c (eval): Ditto.
861 * main.c (main): Ditto.
862 * implicit.c (pattern_search): Ditto.
863 * file.c (parse_prereqs): Ditto.
864 * default.c (set_default_suffixes): Ditto.
866 2009-06-09 Paul Smith <psmith@gnu.org>
868 * commands.c (set_file_variables): If always_make_flag is set,
869 always add the prereq to $?. Fixes Savannah bug #17825.
871 * remake.c (update_file_1): When rebuilding deps of FILE, also try
872 to rebuild the deps of all the also_make targets for that file.
873 Fixes Savannah bug #19108.
875 * implicit.c (pattern_search): Undo test for is_target, added by
876 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
877 Rule Search Algorithm". Fixes Savannah bug #17752.
879 * main.c (clean_jobserver): Clear the jobserver_fds options and
880 set job_slots to the default when we clean up.
881 (define_makeflags): Return the new MAKEFLAGS value.
882 (main): Reset MAKEFLAGS in the environment when we re-exec.
883 Fixes Savannah bug #18124.
885 2009-06-08 Paul Smith <psmith@gnu.org>
887 * read.c (eval): Collapse continuations post-semicolon on target-
888 specific variables. Fixes Savannah bug #17521.
890 2009-06-07 Paul Smith <psmith@gnu.org>
892 * job.c (reap_children): For older systems without waitpid() (are
893 there any of these left?) run wait(2) inside EINTRLOOP to handle
894 EINTR errors. Fixes Savannah bug #16401.
896 * (various): Debug message cleanup. Fixes Savannah bug #16469.
898 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
900 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
901 not the end, to catch second expansion $(eval ...) defining new
902 target/prereq relationships during snap_deps.
903 Fixes Savannah bug #24622.
905 * read.c (record_files): The second-expansion "f->updating" hack
906 was not completely correct: if assumed that the target with
907 commands always had prerequisites; if one didn't then the ordering
908 was messed up. Fixed for now to use f->updating to decide whether
909 to preserve the last element in the deps list... but this whole
910 area of constructing and reversing the deps list is too confusing
911 and needs to be reworked. Fixes Savannah bug #21198.
913 2009-06-06 Paul Smith <psmith@gnu.org>
915 * hash.c (hash_insert): Remove useless test for NULL.
916 Fixes Savannah bug #21823.
918 * make.h: Move SET_STACK_SIZE determination to make.h.
919 * main.c (main): New global variable, STACK_LIMIT, holds the
920 original stack limit when make was started.
921 * job.c (start_job_command): Reset the stack limit, if we changed it.
922 Fixes Savannah bug #22010.
924 * remake.c (check_dep): Only set the target's state to not-started
925 if it's not already running. Found this while testing -j10 builds
926 of glibc: various targets were being rebuilt multiple times.
927 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
930 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
931 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
934 2009-06-04 Paul Smith <psmith@gnu.org>
936 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
938 * maintMakefile: Modify access of config and gnulib Savannah
939 modules to use GIT instead of CVS.
941 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
942 Fixes Savannah bug #24655.
944 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
945 this can happen during some invocations of $(eval ...) for example.
946 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
948 2009-06-02 Paul Smith <psmith@gnu.org>
950 * configure.in: Check for fileno()
951 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
952 for the makefile file so invocations of $(shell ...) don't inherit it.
953 Fixes Savannah bug #24277.
955 2009-06-01 Paul Smith <psmith@gnu.org>
957 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
958 expansion was handled incorrectly. Rework the default goal
959 handling to save the variable only. Remove default_goal_file and
961 * read.c (eval): Check default_goal_var, not default_goal_name.
962 * read.c (record_target_var): Don't check default_goal_file here.
964 2009-05-31 Paul Smith <psmith@gnu.org>
966 * main.c (main): Expand the .DEFAULT_GOAL variable before using
967 it, and if the multi_glob() returns nothing (say it expanded to
968 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
970 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
971 $(and ..) to the reference. Fixes Savannah bug #25694.
973 * make.1: Be clear that some recipes will be executed even with -n.
974 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
976 * doc/make.texi (Override Directive): Make more clear how
977 overrides and appends interact.
978 Elucidates part of Savannah bug #26207.
980 * read.c (record_target_var): Don't reset the origin on
981 target-specific variables; try_variable_definition() will handle
982 this correctly. Fixes Savannah bug #26207.
984 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
985 Fixes Savannah bug #25712.
987 * implicit.c (pattern_search): Keep a pointer to the beginning of
988 the filename and save that instead of the constructed pointer.
989 Fixes Savannah bug #26593.
990 Patch by Mark Seaborn <mrs@mythic-beasts.com>
992 2009-05-30 Paul Smith <psmith@gnu.org>
994 * doc/make.texi (Multi-Line): Add a description of the new abilities
995 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
996 "command sequence" vs. "recipe" syntax.
997 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
998 after a define, to create variables with those flavors.
1000 2009-05-25 Paul Smith <psmith@gnu.org>
1002 Reworked the parser for variable assignments to allow multiple
1003 modifiers, and in any order. Also allows variable and
1004 prerequisites to be modifier names ('export', 'private', etc.)
1006 * NEWS: Add notes about user-visible changes.
1008 * read.c (struct vmodifiers): Remember what modifiers were seen.
1009 (parse_var_assignment): New function to parse variable assignments.
1010 (eval): Call the new function. Handle variable assignments earlier.
1012 * variable.c (parse_variable_definition): Only parse; don't create var.
1013 (assign_variable_definition): Call parse, then create the var.
1015 2009-05-24 Paul Smith <psmith@gnu.org>
1017 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1018 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1020 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1022 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1023 Fixes Savannah bug #25412.
1025 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1026 prototype for xmalloc.
1027 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1028 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1029 Loop over an array of extensions, instead of duplicating the same
1030 code inline. Use SearchPath followed by CreateFile, instead of
1031 the obsolete OpenFile. Fixes Savannah bug #17277.
1032 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1033 to `find_file'. Fixes Savannah bug #25662.
1035 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1037 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1038 Fixes Savannah bug #20495.
1040 2009-02-28 Ralf Wildenhues <address@hidden>
1042 * doc/make.texi (Instead of Execution): Document interaction of
1043 -t with phony targets.
1045 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1047 Introduce a new keyword "private" which applies to target-specific
1048 variables and prevents their values from being inherited.
1050 * variable.h (struct variable): Add private_var flag to each variable.
1051 Add a flag to specify which list entry switches to the parent target.
1052 * variable.c (define_variable_in_set): Initialize private_var flag.
1053 (lookup_variable): Skip private variables in parent contexts.
1054 (initialize_file_variables): Set next_is_parent appropriately.

1063 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
1065 * make.h: Rename savestring to xstrndup.
1066 * commands.c (chop_commands): Ditto.
1067 * function.c (func_foreach): Ditto.
1068 * read.c (eval, record_files): Ditto.

1134 HAVE_DECL_SYS_SIGLIST.
1136 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1137 build does not use child_execute_job.
1139 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1140 export the SHELL environment variable to the child.

1164 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1166 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1167 a more complex value than a simple shell: if it's not a default
1168 shell now then expand it and see if is a default shell then.
1170 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1172 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1173 pathnames, with const strings.
1174 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1175 from the template (used for building from CVS, not a dist).
1177 2007-10-10 Paul Smith <psmith@gnu.org>
1179 * make.h: Add a prototype for w32_kill() (change suggested by

1194 2007-09-11 Paul Smith <psmith@gnu.org>
1196 * doc/make.texi (Special Variables): Moved this into the "How to
1197 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1198 (MAKEFILE_LIST) No longer a section; this was added into the
1199 "Special Variables" section.

1201 (Simple Makefile): Ditto.
1202 (Rule Syntax): Ditto.
1203 (Command Syntax): Ditto.
1204 (Error Messages): Ditto.
1206 2007-09-10 Paul Smith <psmith@gnu.org>
1208 * commands.c (print_commands): Don't print an extra line in the
1209 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1211 * read.c (construct_include_path): Add the full string to the cache; we
1212 were chopping the last char.
1214 * NEWS: Announce the .RECIPEPREFIX special variable.
1215 * variable.c (lookup_special_var): Rename from handle_special_var().
1216 (lookup_variable): Call the new name.
1217 (set_special_var): New function: handle setting of special variables.
1218 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1219 (do_variable_definition): Call it.
1220 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1221 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1222 * main.c (main): Create the .RECIPEPREFIX special variable.
1223 * read.c (eval): Remove the cmd_prefix characters from the command
1224 scripts here, so they're not stored in the commands array at all,
1225 rather than waiting and stripping them out during command construction.
1226 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1228 2007-08-15 Paul Smith <psmith@gnu.org>
1230 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1231 file has had the section info removed, so add some to make.texi
1232 before we include it.
1234 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1236 * remake.c (check_dep): Reset the target state for intermediate
1237 files. They might have been considered before but not updated

1252 2007-07-13 Paul Smith <psmith@gnu.org>
1254 * file.c (expand_deps): Use variable_buffer as the start of the
1255 buffer, not the original pointer (in case it was reallocated).
1256 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1257 Fixes Savannah bug #20452.
1259 2007-07-04 Paul Smith <psmith@gnu.org>

1292 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1293 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1294 Dave Korn <dave.korn@artimi.com>
1296 2007-05-08 Paul Smith <psmith@gnu.org>
1298 Fix Savannah bug #19656:
1300 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1302 * make.h: Change all case-insensitive string compares to use
1303 strcasecmp() (from POSIX). If we don't have that but do have one
1304 of the others, define strcasecmp to be one of those instead. If
1305 we don't have any, declare a prototype for our own version.
1307 * misc.c (strcasecmp): Use this if we can't find any native
1308 case-insensitive string comparison function.
1309 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1310 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1312 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1313 strcasecmp() instead of stricmp().
1314 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1315 instead of strcmpi().
1316 * acinclude.m4: Remove the strcasecmp() check from here.
1318 2007-03-21 Paul Smith <psmith@gnu.org>
1320 * configure.in: Don't turn on case-insensitive file system support
1321 if --disable-... is given. Fixes Savannah bug #19348.
1323 2007-03-19 Paul Smith <psmith@gnu.org>
1325 * ALL: Use the strcache for all file name strings, or other
1326 strings which we will never free. The goal is to save memory by
1327 avoiding duplicate copies of strings. However, at the moment this
1328 doesn't save much memory in most situations: due to secondary
1329 expansion we actually save prerequisite lists twice (once before
1330 the secondary expansion, and then again after it's been parsed
1331 into individual file names in the dep list). We will resolve this
1332 in a future change, by doing the parsing up-front for targets
1333 where secondary expansion is not set.
1335 Moving things into the strcache also allows us to use const
1336 pointers in many more places.
1338 2007-01-03 Paul Smith <psmith@gnu.org>
1340 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1341 the function, not just the first. Fixes Savannah bug #18680.
1343 2006-11-18 Paul Smith <psmith@gnu.org>
1345 * strcache.c (strcache_add_len): Don't allocate a new buffer
1346 unless the string is not already nil-terminated. Technically this
1347 is a violation of the standard, since we may be passed an array
1348 that is not long enough to test one past. However, in make this
1349 is never true since we only use nil-terminated strings or
1350 sub-strings thereof.
1352 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1354 * main.c: New global cmd_prefix, defaults to '\t'.
1355 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1358 * dir.c: Constified.
1359 (dir_contents_file_exists_p): Check for an error return from
1360 readdir(), just in case.
1362 * commands.c: Constified.
1363 * default.c: Constified.
1364 * expand.c: Constified.
1365 * function.c: Partial constification.

1367 * vmsify.c: Constification. Hard to test this but I hope I didn't
1369 * vpath.c: Partial constification.
1370 * w32/pathstuff.c: Partial constification.
1372 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1374 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1375 backslashes and drive letters as absolute.
1377 2006-10-22 Paul Smith <psmith@gnu.org>
1379 * main.c (struct command_switch): Use const and void*.
1381 2006-10-21 Paul Smith <psmith@gnu.org>
1384 * arscan.c: Constified.
1386 2006-09-30 Paul Smith <psmith@gnu.org>
1388 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1389 point to lastword since the example was updated.
1390 Fixes Savannah bug #16304.
1391 (Secondary Expansion): Correct example description.
1392 Fixes Savannah bug #16468.
1393 (Makefile Contents): Clarify that comments cannot appear within
1394 variable references or function calls.
1395 Fixes Savannah bug #16577.
1396 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1397 Fixes Savannah bug #17701.
1398 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1399 (Prerequisite Types): Added an example of using order-only
1400 prerequisites. Fixes Savannah bug #17880.
1401 (Rule Syntax): "lise" -> "list"
1402 (Multiple Rules): ... -> @dots{}
1403 (Splitting Lines): ditto.
1405 * remake.c (update_file_1): Prereqs that don't exist should be
1406 considered changed, for the purposes of $?.
1407 Fixes Savannah bug #16051.
1409 * make.1: Remove extraneous "+".
1410 Fixes Savannah bug #16652.
1412 2006-09-06 Paul D. Smith <psmith@gnu.org>
1414 * configure.in: Include sys/types.h when checking for sys/wait.h.
1416 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1418 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1421 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1422 Normally, it is defined in config.h.
1424 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1427 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1428 sh_chars_sh for Windows platforms that emulate Unix.
1430 2006-05-07 Paul D. Smith <psmith@gnu.org>
1432 * README.OS2.template: Updates provided by Andreas Buening
1433 <andreas.buening@nexgo.de>.

1437 * make.h: Include <direct.h> if HAVE_DIRECT_H.

1446 2006-04-20 Paul D. Smith <psmith@gnu.org>
1448 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1449 that don't have extended grep.
1450 (cvsclean): Use $(PERL) instead of perl.
1452 2006-04-09 Paul D. Smith <psmith@gnu.org>

1456 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1457 inner-scope variables don't mask outer-scope variables.
1459 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1460 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1461 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1462 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1463 values from memory allocation functions: they return void* and so
1464 don't need to be cast. Also remove (char *) casts of arguments to
1467 * configure.in: Remove checks for memcpy/memmove/strchr.
1469 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1471 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp

1475 * variable.c, vpath.c: Ditto.
1477 * make.h (EXIT_FAILURE): Should be 1, not 0.
1479 2006-04-06 Paul D. Smith <psmith@gnu.org>
1481 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1482 require an ISO C 1989 standard compiler and runtime library.

1509 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1510 support from automake, as described in the Texinfo manual.

1514 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1515 with lastslash, since the latter points to filename, not to
1517 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1518 Declare and define sh_chars_sh[].
1520 2006-03-23 Paul D. Smith <psmith@gnu.org>
1522 * configure.in: Look for build.sh.in in $srcdir so it will be
1523 built for remote configurations as well.
1525 * Makefile.am: Make sure to clean up build.sh during distclean.
1526 Fixes Savannah bug #16166.
1528 * misc.c (log_access): Takes a const char *.
1529 * function.c (fold_newlines): Takes an unsigned int *.
1530 Both fixes for Savannah bug #16170.
1532 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1534 * implicit.c (pattern_search): Call set_file_variables only
1535 if we have prerequisites that need second expansion. Fixes
1536 Savannah bug #16140.

1540 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1541 memory on hosts that don't support it directly.
1543 * README.cvs: Add information on steps for making a release (to
1544 make sure I don't forget any).
1546 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1548 (die): Cleanup code was removed from here; call the new function.
1549 (main): If we are re-execing, clean up the jobserver first so we
1550 don't leak file descriptors.
1551 Reported by Craig Fithian <craig.fithian@citigroup.com>
1553 2006-03-17 Paul D. Smith <psmith@gnu.org>

1562 * misc.c (alloc_dep, free_dep): New functions.
1563 (copy_dep_chain): Copy stem.
1564 (free_dep_chain): Use free_dep.
1565 * read.c (record_files): Store stem in the dependency line.
1566 * file.c (expand_deps): Use stem stored in the dependency line. Use

1579 (allocated_variable_append): Don't expand the final result.
1580 Fixes Savannah bug #15913.
1582 2006-03-09 Paul Smith <psmith@gnu.org>
1584 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1585 listed non-existent files as changed. Turns out there's a bug in
1586 the Linux kernel builds which means that this change causes
1587 everything to rebuild every time. We will re-introduce this fix
1588 in the next release, to give them time to fix their build system.
1589 Fixes Savannah bug #16002.
1590 Introduces Savannah bug #16051.

1596 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1598 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1599 locator function find_and_set_default_shell if SHELL came from the
1602 2006-02-20 Paul D. Smith <psmith@gnu.org>
1604 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1605 to be null; don't core in that case.
1607 2006-02-19 Paul D. Smith <psmith@gnu.org>
1609 * commands.c (set_file_variables): Realloc, not malloc, the static
1610 string values to avoid memory leaks.
1612 * expand.c (recursively_expand_for_file): Only set reading_file to
1613 an initialized value.
1615 * implicit.c (pattern_search): We need to make a copy of the stem
1616 if we get it from an intermediate dep, since those get freed.
1618 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1620 (enter_file) [VMS]: Ditto.
1621 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1627 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1628 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1629 the calls to _beginthreadex.
1631 * expand.c (recursively_expand_for_file): Initialize `save' to
1632 prevent compiler warnings.
1634 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1636 * job.c (construct_command_argv_internal): Don't create a temporary
1637 script/batch file if we are under -n. Call _setmode to switch the
1638 script file stream to text mode.
1640 2006-02-17 Paul D. Smith <psmith@gnu.org>
1642 * variable.c (merge_variable_set_lists): Don't try to merge the
1643 global_setlist. Not only is this useless, but it can lead to
1644 circularities in the linked list, if global_setlist->next in one
1645 list gets set to point to another list which also ends in
1647 Fixes Savannah bug #15757.
1649 2006-02-15 Paul D. Smith <psmith@gnu.org>
1651 Fix for Savannah bug #106.
1653 * expand.c (expanding_var): Keep track of which variable we're
1654 expanding. If no variable is being expanded, it's the same as
1656 * make.h (expanding_var): Declare it.
1657 * expand.c (recursively_expand_for_file): Set expanding_var to the
1658 current variable we're expanding, unless there's no file info in
1659 it (could happen if it comes from the command line or a default
1660 variable). Restore it before we exit.
1661 * expand.c (variable_expand_string): Use the expanding_var file
1662 info instead of the reading_file info.
1663 * function.c (check_numeric): Ditto.
1665 (func_wordlist): Ditto.
1666 (func_error): Ditto.

1668 (handle_function): Ditto.
1670 2006-02-14 Paul D. Smith <psmith@gnu.org>
1672 * read.c (eval): Even if the included filenames expands to the
1673 empty string we still need to free the allocated buffer.
1675 * implicit.c (pattern_search): If we allocated a variable set for
1676 an impossible file, free it.
1677 * variable.c (free_variable_set): New function.
1678 * variable.h: Declare it.
1680 * read.c (read_all_makefiles): Makefile names are kept in the
1681 strcache, so there's never any need to alloc/free them.
1684 * main.c (main): Add "archives" to the .FEATURES variable if
1685 archive support is enabled.
1686 * doc/make.texi (Special Variables): Document it.

1696 * (ALL FILES): Updated copyright and license notices.
1698 2006-02-10 Paul D. Smith <psmith@gnu.org>
1700 A new internal capability: the string cache is a read-only cache
1701 of strings, with a hash table interface for fast lookup. Nothing
1702 in the cache will ever be freed, so there's no need for reference
1703 counting, etc. This is the beginning of a full solution for
1704 Savannah bug #15182, but for now we only store makefile names here.
1706 * strcache.c: New file. Implement a read-only string cache.
1707 * make.h: Add prototypes for new functions.
1708 * main.c (initialize_global_hash_tables): Initialize the string cache.
1709 (print_data_base): Print string cache stats.
1710 * read.c (eval_makefile): Use the string cache to store makefile
1711 names. Rewrite the string allocation to be sure we free everything.

1715 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1716 directory time stamp didn't change, except on FAT filesystems.
1717 Suggested by J. David Bryan <jdbryan@acm.org>.

1721 * function.c (func_or): Implement a short-circuiting OR function.
1722 (func_and): Implement a short-circuiting AND function.
1723 (function_table_init): Update the table with the new functions.
1724 * doc/make.texi (Conditional Functions): Changed the "if" section
1725 to one on general conditional functions. Added documentation for
1726 $(and ...) and $(or ...) functions.
1727 * NEWS: Note new $(and ...) and $(or ...) functions.

1732 * job.c (new_job): Cache dontcare flag.
1733 * job.c (reap_children): Use cached dontcare flag instead of the
1734 one in struct file. Fixes Savannah bug #15641.
1736 2006-02-06 Paul D. Smith <psmith@gnu.org>
1738 * vpath.c (selective_vpath_search): If the file we find has a
1739 timestamp from -o or -W, use that instead of the real time.
1740 * remake.c (f_mtime): If the mtime is a special token from -o or
1741 -W, don't overwrite it with the real mtime.
1742 Fixes Savannah bug #15341.

1759 Fixes Savannah bug #15533.
1760 * filedef.h (struct file): Add a new LAST pointer.
1762 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1763 the comparison. For 64-bits systems the result of the subtraction
1764 might not fit into an int. Use comparison instead.
1765 Fixes Savannah bug #15534.
1767 * doc/make.texi: Update the chapter on writing commands to reflect
1768 the changes made in 3.81 for backslash/newline and SHELL handling.

1788 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1790 * remake.c (update_goal_chain): Set g->changed instead of
1791 incrementing it, as it is only 8-bit wide, and could overflow if
1792 many commands got started in update_file.
1794 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1796 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1797 MAXIMUM_WAIT_OBJECTS.
1798 (process_wait_for_any_private): Change dimension of handles[]
1799 array to MAXIMUM_WAIT_OBJECTS.

1805 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1806 are already more children than sub_proc.c can handle, behave as if
1807 the load were too high.
1808 (start_job_command): Fix a typo in error message when process_easy
1811 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1813 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1814 the shell is not sh.exe.
1816 * job.c (create_batch_file): Renamed from create_batch_filename;
1817 all callers changed. Don't close the temporary file; return its
1818 file descriptor instead. New arg FD allows to return the file
1820 (construct_command_argv_internal): Use _fdopen instead of fopen to
1821 open the batch file.
1823 2006-01-04 Paul D. Smith <psmith@gnu.org>
1825 * readme.vms: Updates for case-insensitive VMS file systems from

1846 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1847 disable warnings for MSC.
1848 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1850 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1852 * doc/make.texi (Execution): Add a footnote about changes in
1853 handling of backslash-newline sequences. Mention the differences
1854 on MS-DOS and MS-Windows.
1856 * NEWS: More details about building the MinGW port and a pointer
1857 to README.W32. Fix the section name that describes the new
1858 backward-incompatible processing of backslash-newline sequences.
1859 The special processing of SHELL set to "cmd" is only relevant to
1860 MS-Windows, not MS-DOS.
1862 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1864 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1865 to DWORD, to avoid compiler warnings.
1866 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1867 use %ld in format, to avoid compiler warnings.

1887 * make.1: Fix some display errors and document all existing options.
1888 Patch by Mike Frysinger <vapier@gentoo.org>.
1890 2005-12-11 Paul D. Smith <psmith@gnu.org>
1892 * implicit.c (pattern_search): If 2nd expansion is not set for
1893 this implicit rule, replace the pattern with the stem directly,
1894 and don't re-expand the variable list. Along with the other
1895 .SECONDEXPANSION changes below, fixes bug #13781.
1897 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1899 * implicit.c (pattern_search): Mark other files that this rule
1900 builds as targets so that they are not treated as intermediates

1903 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1905 * remake.c (notice_finished_file): Propagate the change of

1927 creating a distribution, so don't do it for "all".
1929 2005-10-24 Paul D. Smith <psmith@gnu.org>

1935 * doc/make.texi (Secondary Expansion): Document the
1936 .SECONDEXPANSION special target and its behavior.

1944 * filedef.h (parse_prereqs): Declare a prototype.
1945 * implicit.c (pattern_search): Initialize the new staticpattern
1947 * main.c (second_expansion): Declare a global variable to remember
1948 if the special target has been seen. Initialize the new
1949 staticpattern field for prerequisites.
1950 * make.h: Extern for second_expansion.
1951 * misc.c (free_dep_chain): New function: frees a struct dep list.
1952 * read.c (read_all_makefiles): Initialize the staticpattern field.

1957 Set the staticpattern field for prereqs of static pattern targets.
1959 2005-10-16 Paul D. Smith <psmith@gnu.org>
1961 * main.c (main): Set CURDIR to be a file variable instead of a
1962 default, so that values of CURDIR inherited from the environment
1963 won't override the make value.
1965 2005-09-26 Paul D. Smith <psmith@gnu.org>
1967 * job.c (construct_command_argv_internal): If the line is empty
1968 remember to free the temporary argv strings.

1977 2005-08-29 Paul D. Smith <psmith@gnu.org>
1979 * function.c (func_error): On Windows, output from $(info ...)
1980 seems to come in the wrong order. Try to force it with fflush().
1982 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1984 * read.c (record_files): Move code that sets stem for static
1985 pattern rules out of the if (!two_colon) condition so it is
1986 also executed for two-colon rules. Fixes Savannah bug #13881.
1988 2005-08-08 Paul D. Smith <psmith@gnu.org>
1990 * make.h: Don't test that __STDC__ is non-0. Some compilers

1999 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2000 If make is running in parallel without -k and two jobs die in a
2001 row, but not too close to each other, then make will quit without
2002 waiting for the rest of the jobs to die.
2004 * main.c (die): Don't reset err before calling reap_children() the
2005 second time: we still want it to be in the error condition.
2006 * job.c (reap_children): Use a static variable, rather than err,
2007 to control whether or not the error message should be printed.
2009 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2011 * w32/subproc/sub_proc.c: Include signal.h.
2012 (process_pipe_io, process_file_io): Pass a pointer to a local
2013 DWORD variable to GetExitCodeProcess. If the exit code is
2014 CONTROL_C_EXIT, put SIGINT into pproc->signal.

2023 doing anything else. When we are done, close the main thread
2024 handle and exit with status 130.

2028 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2031 * main.c (find_and_set_default_shell): If found a DOSish shell,

2033 findings in debug mode.
2035 * job.c (construct_command_argv_internal): Check unixy_shell, not
2036 no_default_sh_exe, to decide whether to use Unixy or DOSish
2039 * README.W32: Update with info about the MinGW build.
2041 * build_w32.bat: Support MinGW.

2046 printing DWORD args.
2048 * function.c (windows32_openpipe): Fix format strings for printing
2051 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and

2078 * config.h.W32.template: Reorder to match the standard config.h,
2079 for easier comparisons.

2085 arithmetic to avoid a warning.
2086 * main.c (switches): Add full-fledged final initializer.
2088 2005-07-06 Paul D. Smith <psmith@gnu.org>
2090 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2091 * signame.c (strsignal): If we found _sys_siglist[] or
2092 __sys_siglist[] use those instead of sys_siglist[].

2111 2005-06-28 Paul D. Smith <psmith@gnu.org>
2113 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2114 declaration was checked but not present.
2116 2005-06-27 Paul D. Smith <psmith@gnu.org>
2118 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2119 to unsigned long. Fixes Savannah bug #13550.
2121 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2122 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2123 Fixes Savannah bug #13551.
2125 2005-06-26 Paul D. Smith <psmith@gnu.org>
2127 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2128 it if ANSI_STRING is not set.
2130 2005-06-25 Paul D. Smith <psmith@gnu.org>
2132 * read.c (eval): If no filenames are passed to any of the
2133 "include" variants, don't print an error.
2134 * doc/make.texi (Include): Document this.
2135 Fixes Savannah bug #1761.
2137 * job.c (construct_command_argv_internal): Sanitize handling of
2138 backslash/newline pairs according to POSIX: that is, keep the
2139 backslash-newline in the command script, but remove a following
2140 TAB character, if present. In the fast path, make sure that the
2141 behavior matches what the shell would do both inside and outside
2142 of quotes. In the slow path, quote the backslash and put a
2143 literal newline in the string.
2144 Fixes Savannah bug #1332.
2145 * doc/make.texi (Execution): Document the new behavior and give
2147 * NEWS: Make a note of the new behavior.
2149 * make.h [WINDOWS32]: #include <direct.h>.
2150 Fixes Savannah bug #13478.
2152 * remake.c (name_mtime): If the stat() of a file fails and the -L
2153 option was given and the file is a symlink, take the best mtime of
2154 the symlink we can get as the mtime of the file and don't fail.
2155 Fixes Savannah bug #13280.
2157 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2158 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2159 inside a variable reference. Make this function static as it's
2161 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2162 parsing an unexpanded line looking for semicolons.
2163 Fixes Savannah bug #1454.
2164 * misc.c (remove_comments): Move this to read.c and make it static
2165 as it's only used there. Call find_char_unquote() with new arg.
2166 * make.h: Remove prototypes for find_char_unquote() and
2167 remove_comments() since they're static now.
2169 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2170 its export flag and obtain its value. When we need to re-exec,
2171 increment the value and add it into the environment.
2172 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2173 * NEWS: Mention MAKE_RESTARTS.
2174 * main.c (always_make_set): New variable. Change the -B option to
2175 set this one instead.
2176 (main): When checking makefiles, only set always_make_flag if
2177 always_make_set is set AND the restarts flag is 0. When building
2178 normal targets, set it IFF always_make_set is set.
2179 (main): Avoid infinite recursion with -W, too: only set what-if
2180 files to NEW before we check makefiles if we've never restarted
2181 before. If we have restarted, set what-if files to NEW _after_ we
2183 Fixes Savannah bug #7566:
2185 2005-06-17 Paul D. Smith <psmith@gnu.org>
2187 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2188 in the prerequisites list.
2190 2005-06-12 Paul D. Smith <psmith@gnu.org>
2192 Fix Savannah bug # 1328.
2194 * configure.in: Check for atexit().
2195 * misc.c (close_stdout): Test stdout to see if writes to it have
2196 failed. If so, be sure to exit with a non-0 error code. Based on
2197 code found in gnulib.
2198 * make.h: Prototype.
2199 * main.c (main): Install close_stdout() with atexit().
2201 2005-06-10 Paul D. Smith <psmith@gnu.org>
2203 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2205 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2206 headers; make vmsWaitForChildren() static; extern vmsify().
2207 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2208 Don't create child_execute_job() here (it's in vmsjobs.c).
2209 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2211 2005-06-09 Paul D. Smith <psmith@gnu.org>
2213 * variable.c (push_new_variable_scope): File variables point
2214 directly to the global_setlist variable. So, inserting a new
2215 scope in front of that has no effect on those variables: they
2216 don't go through current_variable_set_list. If we're pushing a
2217 scope and the current scope is global, push it "the other way" so
2218 that the new setlist is in the global_setlist variable, and
2219 next points to a new setlist with the global variable set.
2220 (pop_variable_scope): Properly undo a push with the new
2222 Fixes Savannah bug #11913.
2224 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2226 * job.c (reap_children): Don't die of the command failed but
2227 the dontcare flag is set. Fixes Savannah bug #13216.
2229 * implicit.c (pattern_search): When creating a target from
2230 an implicit rule match, lookup pattern target and set precious
2231 flag in a newly created target. Fixes Savannah bug #13218.
2233 2005-05-13 Paul D. Smith <psmith@gnu.org>
2235 Implement "if... else if... endif" syntax.
2237 * read.c (eval): Push all checks for conditional words ("ifeq",
2238 "else", etc.) down into the conditional_line() function.
2239 (conditional_line): Rework to allow "else if..." clause. New
2240 return value -2 for lines which are not conditionals. The
2241 ignoring flag can now also be 2, which means "already parsed a
2242 true branch". If that value is seen no other branch of this
2243 conditional can be considered true. In the else parsing if there
2244 is extra text after the else, invoke conditional_line()
2245 recursively to see if it's another conditional. If not, it's an
2246 error. If so, raise the conditional value to this level instead
2247 of creating a new conditional nesting level. Special check for
2248 "else" and "endif", which aren't allowed on the "else" line.
2249 * doc/make.texi (Conditional Syntax): Document the new syntax.
2251 2005-05-09 Paul D. Smith <psmith@gnu.org>
2253 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2254 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2255 recurses to the w32 directory, even on non-Windows systems. Use
2256 the method suggested in the automake manual.
2257 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2258 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2260 2005-05-07 Paul D. Smith <psmith@gnu.org>
2262 * main.c (die): If we're dying with a fatal error (not that a
2263 command has failed), write back any leftover tokens before we go.
2265 * job.c (set_child_handler_action_flags): If there are jobs
2266 waiting for the load to go down, set an alarm to go off in 1
2267 second. This allows us to wake up from a potentially long-lasting
2268 read() and start a new job if the load has gone down. Turn it off
2270 (job_noop): Dummy signal handler function.
2271 (new_job): Invoke it with the new semantics.
2273 * docs/make.texi: Document secondary expansion. Various cleanups
2276 2005-05-03 Paul D. Smith <psmith@gnu.org>
2278 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2279 the targets which are to ultimately be made are called "goals";
2280 see the GNU make manual. Also, MAKECMDGOALS, etc.
2282 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2283 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2284 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2286 2005-05-02 Paul D. Smith <psmith@gnu.org>
2288 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2289 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2290 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2291 functions to vmsjobs.c. #include it into jobs.c.
2293 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2294 jobserver tokens. I found that this happens when an exported
2295 recursive variable contains a $(shell ...) function reference: in
2296 this situation we could "forget" to write back a token.
2298 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2299 we have. It's not reliable to depend on the number of children in
2300 our linked list so keep a separate count.
2301 (new_job): Check jobserver_tokens rather than children &&
2302 waiting_jobs. Increment jobserver_tokens when we get one.
2303 (free_child): If jobserver_tokens is 0, internal error. If it's
2304 >1, write a token back to the jobserver pipe (we don't write a
2305 token for the "free" job). Decrement jobserver_tokens.
2307 * main.c: Add variable master_job_slots.
2308 (main): Set it to hold the number of jobs requested if we're the
2309 master process, when using the jobserver.
2310 (die): Sanity checks: first test jobserver_tokens to make sure
2311 this process isn't holding any tokens we didn't write back.
2312 Second, if master_job_slots is set count the tokens left in the
2313 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2315 2005-04-24 Paul D. Smith <psmith@gnu.org>
2317 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2318 with -l# can lose jobserver tokens, because waiting jobs are not
2319 consulted properly when checking for the "free" token.
2321 * job.c (free_child): Count waiting_jobs as having tokens.
2322 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2323 handle jobs waiting for the load to drop.
2325 2005-04-23 Paul D. Smith <psmith@gnu.org>
2327 * main.c (main): Be careful to not core if a variable setting in
2328 the environment doesn't contain an '='. This is illegal but can
2329 happen in broken setups.
2330 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2332 2005-04-12 Paul D. Smith <psmith@gnu.org>
2334 The second expansion feature causes significant slowdown. Timing
2335 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2336 read the makefile before the feature, to 11+s to do the same
2337 operations after the feature. Additionally, memory usage
2338 increased drastically. To fix this I added some intelligence that
2339 avoids the overhead of the second expansion unless it's required.
2341 * dep.h: Add a new boolean field, need_2nd_expansion.
2343 * read.c (eval): When creating the struct dep for the target,
2344 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2345 (record_files): If there's a "%" in a static pattern rule, it gets
2346 converted to "$*" so set need_2nd_expansion to 1.
2348 * file.c (expand_deps): Rework to be more efficient. Only perform
2349 initialize_file_variables(), set_file_variables(), and
2350 variable_expand_for_file() if the need_2nd_expansion is set.
2352 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2353 (pattern_search): Ditto.
2354 * main.c (handle_non_switch_argument): Ditto.
2356 * read.c (read_all_makefiles): Ditto.
2357 (eval_makefile): Ditto.
2359 2005-04-07 Paul D. Smith <psmith@gnu.org>
2361 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2362 * variable.c (sync_Path_environment): Ditto.
2363 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2365 * main.c (main): Define the .FEATURES variable.
2366 * NEWS: Announce .FEATURES.
2367 * doc/make.texi (Special Variables): Document .FEATURES.
2369 * remake.c (check_dep): If a file is .PHONY, update it even if
2370 it's marked intermediate. Fixes Savannah bug #12331.
2372 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2374 * file.c (expand_deps): Factor out the second expansion and
2375 prerequisite line parsing logic from snap_deps().
2377 * file.c (snap_deps): Use expand_deps(). Expand and parse
2378 prerequisites of the .SUFFIXES special target first. Fixes
2379 Savannah bug #12320.
2381 2005-03-13 Paul D. Smith <psmith@gnu.org>
2383 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2386 2005-03-11 Paul D. Smith <psmith@gnu.org>
2388 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2389 available, not undefined (from Earnie Boyd).
2391 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2393 * implicit.c (pattern_search): Mark an intermediate target as
2394 precious if it happened to be a prerequisite of some (other)
2395 target. Fixes Savannah bug #12267.
2397 2005-03-09 Paul D. Smith <psmith@gnu.org>
2399 * read.c (eval_makefile): Add alloca(0).
2400 (eval_buffer): Ditto.
2402 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2404 * main.c (main): Use o_file instead of o_default when defining
2405 the .DEFAULT_TARGET special variable.
2406 * read.c (eval): Use define_variable_global() instead of
2407 define_variable() when setting new value for the .DEFAULT_TARGET
2408 special variable. Fixes Savannah bug #12266.
2410 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2412 * imlicit.c (pattern_search): Mark files for which an implicit
2413 rule has been found as targets. Fixes Savannah bug #12202.
2415 2005-03-04 Paul D. Smith <psmith@gnu.org>
2418 * doc/make.texi (Automatic Variables): Document $|.
2420 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2422 * read.c (record_files): Instead of substituting % with
2423 actual stem value in dependency list replace it with $*.
2424 This fixes stem triple expansion bug.
2426 * implicit.c (pattern_search): Copy stem to a separate
2427 buffer and make it a properly terminated string. Assign
2428 this buffer instead of STEM (which is not terminated) to
2429 f->stem. Instead of substituting % with actual stem value
2430 in dependency list replace it with $*. This fixes stem
2431 triple expansion bug.
2433 2005-03-01 Paul D. Smith <psmith@gnu.org>
2435 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2436 on Windows, as it takes a handle not a pid. Just exit.
2437 Fix from patch #3679, provided by Alessandro Vesely.
2439 * configure.in: Update check for sys_siglist[] from autoconf manual.
2440 * signame.c (strsignal): Update to use the new autoconf macro.
2442 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2444 * read.c (record_files): Add a check for the list of prerequisites
2445 of a static pattern rule being empty. Fixes Savannah bug #12180.
2447 2005-02-28 Paul D. Smith <psmith@gnu.org>
2449 * doc/make.texi (Text Functions): Update docs to allow the end
2450 ordinal for $(wordlist ...) to be 0.
2451 * function.c (func_wordlist): Fail if the start ordinal for
2452 $(wordlist ...) is <1. Matches documentation.
2453 Resolves Savannah support request #103195.
2455 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2456 previously we were stopping when !-q, exactly the opposite. This
2457 has been wrong since version 1.34, in 1994!
2458 (update_file): If we got an error don't break out to run more
2459 double-colon rules: just return immediately.
2460 Fixes Savannah bug #7144.
2462 2005-02-27 Paul D. Smith <psmith@gnu.org>
2464 * misc.c (end_of_token): Make argument const.
2465 * make.h: Update prototype.
2467 * function.c (abspath, func_realpath, func_abspath): Use
2468 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2469 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2470 * read.c (record_files): Ditto.
2471 * variable.c (do_variable_definition): Ditto.
2473 * function.c (func_error): Create a new function $(info ...) that
2474 simply prints the message to stdout with no extras.
2475 (function_table_init): Add new function to the table.
2476 * NEWS: Add $(info ...) reference.
2477 * doc/make.texi (Make Control Functions): Document it.
2479 New feature: if the system supports symbolic links, and the user
2480 provides the -L/--check-symlink-time flag, then use the latest
2481 mtime between the symlink(s) and the target file.
2483 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2484 readlink(). If both are available, define MAKE_SYMLINKS.
2485 * main.c: New variable: check_symlink_flag.
2486 (usage): Add a line for -L/--check-symlink-times to the help string.
2487 (switches): Add -L/--check-symlink-times command line argument.
2488 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2489 print a warning and disable it again.
2490 * make.h: Declare check_symlink_flag.
2491 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2492 if the file is a symlink then check each link in the chain and
2493 choose the NEWEST mtime we find as the mtime for the file. The
2494 newest mtime might be the file itself!
2495 * NEWS: Add information about this new feature.
2496 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2498 Avoid core dumps described in Savannah bug # 12124:
2500 * file.c: New variable snapped_deps remember whether we've run
2502 (snap_deps): Set it.
2503 * filedef.h: Extern it.
2504 * read.c (record_files): Check snapped_deps; if it's set then
2505 we're trying to eval a new target/prerequisite relationship from
2506 within a command script, which we don't support. Fatal.
2508 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2510 Implementation of the .DEFAULT_TARGET special variable.
2512 * read.c (eval): If necessary, update default_target_name when
2514 * read.c (record_files): Update default_target_file if
2515 default_target_name has changed.
2516 * main.c (default_target_name): Define.
2517 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2518 default_target_name is set use default_target_file as a root
2520 * filedef.h (default_target_name): Declare.
2521 * dep.h (free_dep_chain):
2522 * misc.c (free_dep_chain): Change to operate on struct nameseq
2523 and change name to free_ns_chain.
2524 * file.c (snap_deps): Update to use free_ns_chain.
2526 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2528 Implementation of the second expansion in explicit rules,
2529 static pattern rules and implicit rules.
2531 * read.c (eval): Refrain from chopping up rule's dependencies.
2532 Store them in a struct dep as a single dependency line. Remove
2533 the code that implements SySV-style automatic variables.
2535 * read.c (record_files): Adjust the code that handles static
2536 pattern rules to expand all percents instead of only the first
2537 one. Reverse the order in which dependencies are stored so that
2538 when the second expansion reverses them again they appear in
2539 the makefile order (with some exceptions, see comments in
2540 the code). Remove the code that implements SySV-style automatic
2543 * file.c (snap_deps): Implement the second expansion and chopping
2544 of dependency lines for explicit rules.
2546 * implicit.c (struct idep): Define an auxiliary data type to hold
2547 implicit rule's dependencies after stem substitution and
2550 * implicit.c (free_idep_chain): Implement.
2552 * implicit.c (get_next_word): Implement helper function for
2553 parsing implicit rule's dependency lines into words taking
2554 into account variable expansion requests. Used in the stem
2557 * implicit.c (pattern_search): Implement the second expansion
2558 for implicit rules. Also fixes bug #12091.
2560 * commands.h (set_file_variables): Declare.
2561 * commands.c (set_file_variables): Remove static specifier.
2563 * dep.h (free_dep_chain): Declare.
2564 * misc.c (free_dep_chain): Implement.
2566 * variable.h (variable_expand_for_file): Declare.
2567 * expand.c (variable_expand_for_file): Remove static specifier.
2569 * make.h (strip_whitespace): Declare.
2570 * function.c (strip_whitespace): Remove static specifier.
2572 2005-02-26 Paul D. Smith <psmith@gnu.org>
2574 * main.c (main): Check for ferror() when reading makefiles from stdin.
2575 Apparently some shells in Windows don't close pipes properly and
2578 2005-02-24 Jonathan Grant <jg@jguk.org>
2580 * configure.in: Add MinGW configuration options, and extra w32 code
2582 * Makefile.am: Add MinGW configuration options, and extra w32 code
2584 * main.c: Determine correct program string (after last \ without .exe).
2585 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2587 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2588 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2589 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2590 environment support.
2592 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2594 * function.c (func_shell): When initializing error_prefix, check
2595 that reading file name is not null. This fixes long-standing
2596 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2598 2005-02-09 Paul D. Smith <psmith@gnu.org>
2600 * maintMakefile: Update the CVS download URL to simplify them.
2601 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2602 downloading the .texi files from Savannah now.
2604 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2606 * main.c (handle_non_switch_argument): Only add variables to
2607 command_variables if they're not already there: duplicate settings
2608 waste space and can be confusing to read.
2610 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2611 this header is never included by non-WINDOWS32 code, and it
2612 requires <config.h> to define which isn't always included first.
2614 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2615 testing MINGW32 versions.
2617 * main.c (log_working_directory): flush stdout to be sure the WD
2618 change is printed before any stderr messages show up.
2620 2005-02-01 Paul D. Smith <psmith@gnu.org>
2622 * maintMakefile (po_repo): Update the GNU translation site URL.
2624 2004-12-01 Paul D. Smith <psmith@gnu.org>
2626 * main.c (main): Change char* env_shell to struct variable shell_var.
2627 * variable.c (target_environment): Use new shell_var.
2629 2004-11-30 Paul D. Smith <psmith@gnu.org>
2631 * configure.in: The old way we avoided creating build.sh from
2632 build.sh.in before build.sh.in exists doesn't work anymore; we
2633 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2634 the help!). This also keeps automake from complaining.
2635 * Makefile.am (README): Add a dummy target so automake won't
2636 complain that this file doesn't exist when we checkout from CVS.
2637 * maintMakefile (.dep_segment): Rewrite this rule since newer
2638 versions of automake don't provide DEP_FILES.
2640 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2642 Implementation of `realpath' and `abspath' built-in functions.
2644 * configure.in: Check for realpath.
2645 * function.c (abspath): Return an absolute file name that does
2646 not contain any `.' or `..' components, nor repeated `/'.
2647 * function.c (func_abspath): For each name call abspath.
2648 * function.c (func_realpath): For each name call realpath
2649 from libc or delegate to abspath if realpath is not available.
2650 * doc/make.texi (Functions for File Names): Document new functions.
2651 * doc/make.texi (Quick Reference): Ditto.
2653 2004-11-28 Paul D. Smith <psmith@gnu.org>
2655 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2656 arguments. Fixes bug #10252.
2658 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2660 * main.c (main): Set SHELL to v_noexport by default. Remember the
2661 original environment setting of SHELL in the env_shell variable.
2662 * main.h: Export new env_shell variable.
2663 * variable.c (target_environment): If we find a v_noexport
2664 variable for SHELL, add a SHELL variable with the env_shell value.
2665 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2666 * doc/make.texi (Variables/Recursion): Ditto.
2668 2004-11-28 Paul D. Smith <psmith@gnu.org>
2670 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2671 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2672 Patch by Alessandro Vesely.
2674 2004-11-12 Paul D. Smith <psmith@gnu.org>
2676 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2677 the command line if it's inside a string.
2678 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2680 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2682 * function.c (func_lastword): New function: return last word
2683 from the list of words.
2684 * doc/make.texi: Document $(lastword ). Fix broken links in
2685 Quick Reference section.
2687 2004-10-06 Paul D. Smith <psmith@gnu.org>
2689 Apply patch from Alessandro Vesely, provided with bug # 9748.
2690 Fix use of tmpnam() to work with Borland C.
2692 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2693 construction of a temporary filename, and call new function
2694 create_batch_filename().
2695 (create_batch_filename) [WINDOWS32]: New function to create a
2698 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2700 * read.c (record_target_var): Expand simple pattern-specific
2702 * variable.c (initialize_file_variables): Do not expand simple
2703 pattern-specific variable.
2705 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2707 * remake.c (update_file_1): When rebuilding makefiles inherit
2708 dontcare flag from a target that triggered update.
2710 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2712 * variable.c (initialize_file_variables): Mark pattern-specific
2713 variable as a per-target and copy export status.
2715 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2717 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2719 * implicit.c (pattern_search): When considering an implicit rule's
2720 prerequisite check that it is actually a target rather then
2721 just an entry in the file hashtable.
2723 2004-09-21 Paul D. Smith <psmith@gnu.org>
2725 * read.c (readstring): Fix some logic errors in backslash handling.
2726 (eval): Remove some unnecessary processing in buffer handling.
2727 (record_target_var): Assert that parse_variable_definition() succeeded.
2728 Reported by: Markus Mauhart <qwe123@chello.at>.
2730 * misc.c: Removed the sindex() function. All instances of this
2731 function were trivially replaceable by the standard strstr()
2732 function, and that function will always have better (or certainly
2733 no worse) performance than the very simple-minded algorithm
2734 sindex() used. This can matter with complex makefiles.
2735 * make.h: Remove the prototype for sindex().
2736 * function.c (subst_expand): Convert sindex() call to strstr().
2737 This means we no longer need to track the TLEN value so remove that.
2738 (func_findstring): Convert sindex() to strstr().
2739 * commands.c (chop_commands): Convert sindex() calls to strstr().
2740 Suggested by: Markus Mauhart <qwe123@chello.at>.
2742 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2743 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2744 If SHELL is set to CMD.EXE then assume it's batch-mode and
2745 non-unixy. I wrote the code differently from the patch, though,
2746 to make it safer. This also resolves bug #9174.
2748 2004-09-20 Paul D. Smith <psmith@gnu.org>
2750 * expand.c (variable_expand_string): Modify to invoke
2751 patsubst_expand() instead of subst_expand(); the latter didn't
2752 handle suffix patterns correctly.
2753 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2754 was used only from variable_expand_string() and is no longer used
2756 (func_subst): Ditto, on call to subst_expand().
2757 (patsubst_expand): Require the percent pointers to point to the
2758 character after the %, not to the % itself.
2759 * read.c (record_files): New call criteria for patsubst_expand().
2760 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2761 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2763 2004-09-19 Paul D. Smith <psmith@gnu.org>
2765 * function.c (subst_expand): Fix a check in by_word: look for a
2766 previous blank if we're beyond the beginning of the string, not
2767 the beginning of the word.
2768 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2770 2004-05-16 Paul D. Smith <psmith@gnu.org>
2772 * remake.c (update_goal_chain): Change the argument specifying
2773 whether we're rebuilding makefiles to be a global variable,
2774 REBUILDING_MAKEFILES.
2775 (complain): Extract the code that complains about no rules to make
2776 a target into a separate function.
2777 (update_file_1): If we tried to rebuild a file during the makefile
2778 rebuild phase and it was dontcare, then no message was printed.
2779 If we then try to build the same file during the normal build,
2780 print a message this time.
2781 (remake_file): Don't complain about un-remake-able files when
2782 we're rebuilding makefiles.
2784 2004-05-11 Paul D. Smith <psmith@gnu.org>
2786 * job.c (construct_command_argv_internal): OS/2 patches from
2787 Andreas Buening <andreas.buening@nexgo.de>.
2789 2004-05-10 Paul D. Smith <psmith@gnu.org>
2791 * remake.c (update_file): Don't walk the double-colon chain unless
2792 this is a double-colon rule. Fix suggested by Boris Kolpackov
2793 <boris@kolpackov.net>.
2795 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2796 * readme.vms: New section describing OpenVMS support and issues.
2797 * default.c (default_variables): Add support for IA64.
2798 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2799 without some privilege aborts make with the error
2800 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2801 pressing Ctrl+Y and the input device is no terminal. The change
2802 catches this error and just continues.
2804 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2806 2004-04-25 Paul D. Smith <psmith@gnu.org>
2808 * commands.c (set_file_variables): Set $< properly in the face of
2809 order-only prerequisites.
2810 Patch from Boris Kolpackov <boris@kolpackov.net>
2812 2004-04-21 Bob Byrnes <byrnes@curl.com>
2814 * main.c (main): Notice failures to remake makefiles.
2816 2004-03-28 Paul D. Smith <psmith@gnu.org>
2818 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2820 * job.c: No default shell for RISC OS.
2821 (load_too_high): Hard-code the return to 1.
2822 (construct_command_argv_internal): No sh_chars or sh_cmds.
2823 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2825 2004-03-20 Paul D. Smith <psmith@gnu.org>
2827 * variable.c (do_variable_definition): Don't append from the
2828 global set if a previous non-appending target-specific variable
2829 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2832 * expand.c (reference_variable): Don't give up on variables with
2833 no value that have the target-specific append flag set: they might
2834 have a value after all. Reported by Oliver Schmidt
2835 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2836 <nikulin@dx1cmd.inp.nsk.su>.
2838 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2839 refer to absolute pathnames in directories that don't exist: some
2840 portion of the makefile could create those directories before we
2841 match the pattern. Fixes bugs #775 and #108.
2843 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2845 * main.c (main): Free makefile_mtimes if we have any.
2846 * README.W32.template: Update documentation for the current status
2847 of the MS-Windows port.
2848 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2849 environment variable is sometimes already defined which causes the
2851 * main.c (debug_signal_handler): Only define this function if
2852 SIGUSR1 is available.
2854 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2856 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2857 * README.OS2.template: Documentation updates.
2858 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2859 link line for safety.
2860 * maintMakefile (build.sh.in): Remove an extraneous ")".
2861 * job.c (child_execute_job): Close saved FDs.
2862 * job.c (exec_command) [OS/2]: exec_command(): If the command
2863 can't be exec'ed and if the shell is not Unix-sh, then try again
2864 with argv = { "cmd", "/c", ... }. Normally, this code is never
2865 reached for the cmd shell unless the command really doesn't exist.
2866 (construct_command_argv_internal) [OS/2]: The code for cmd
2867 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2868 The CMD builtin commands are case insensitive so use strcasecmp().
2870 2004-03-19 Paul D. Smith <psmith@gnu.org>
2872 * read.c (do_define): Re-order line counter increment so the count
2873 is accurate (we were losing one line per define). Reported by
2874 Dave Yost <Dave@Yost.com>.
2876 2004-03-06 Paul D. Smith <psmith@gnu.org>
2878 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2880 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2881 * misc.c (message,error,fatal): Ditto.
2882 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2883 * config.h.W32.template: Ditto.
2884 * config.h-vms.template: Ditto.
2885 * config.ami.template: Ditto.
2887 2004-03-04 Paul D. Smith <psmith@gnu.org>
2889 * README.template: Add a note about broken /bin/sh on SunOS
2890 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2892 * misc.c (message, error, fatal): Don't use "..." if we're using
2893 varargs. ansi2knr should handle this but it doesn't work: it
2894 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2895 done. On many systems (SunOS for example) va_dcl is a #define.
2896 So, force the use of the non-"..." version on pre-ANSI compilers.
2898 * maintMakefile (sign-dist): Create some rules to help automate
2899 the new GNU ftp upload method.
2901 2004-02-24 Paul D. Smith <psmith@gnu.org>
2903 * config.h.W32.template: Add HAVE_STDARG_H
2904 * config.h-vms.template: Ditto.
2905 * config.ami.template: Ditto.
2907 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2909 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2910 * build_w32.bat: Remove extra "+".
2912 2004-02-23 Paul D. Smith <psmith@gnu.org>
2914 * make.h: Create an UNUSED macro to mark unused parameters.
2915 * (many): Clean up warnings by applying UNUSED, fixing
2916 signed/unsigned incompatibilities, etc.
2918 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2920 * filedef.h: Name the command_state enumeration.
2921 * file.c (set_command_state): Use the enumeration in the function
2924 * configure.in: Explicitly set SET_MAKE to empty, to disable
2925 MAKE=make even when no make already exists. Fix bug #3823.
2927 2004-02-22 Paul D. Smith <psmith@gnu.org>
2929 * maintMakefile: Perl script to clean up all non-CVS files. Use
2930 it on all the subdirectories for the cvs-clean target.
2932 * main.c (decode_switches): Require non-empty strings for all our
2933 string command-line options. Fixes Debian bug # 164165.
2935 * configure.in: Check for stdarg.h and varargs.h.
2936 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2937 for printing messages.
2938 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2943 A number of patches for OS/2 support from Andreas Buening
2944 <andreas.buening@nexgo.de>:
2946 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2947 disable the SIGCHLD handler.
2948 (reap_children) [OS/2]: Remove special handling of job_rfd.
2949 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2950 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2951 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2952 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2953 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2956 2004-02-21 Paul D. Smith <psmith@gnu.org>
2958 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2959 <mail@kristov.de> reports that if process_begin() fails we don't
2960 handle the error condition correctly in all cases.
2961 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2962 to have a newline on the message.
2964 * job.c (construct_command_argv_internal): Add "test" to UNIX
2965 sh_cmds[]. Fixes Savannah bug # 7606.
2967 2004-02-04 Paul D. Smith <psmith@gnu.org>
2969 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2970 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2971 Hartmut Becker <Hartmut.Becker@hp.com>.
2973 2004-01-21 Paul D. Smith <psmith@gnu.org>
2975 * job.c (load_too_high): Implement an algorithm to control the
2976 "thundering herd" problem when using -l to control job creation
2977 via the load average. The system only recomputes the load once a
2978 second but we can start many jobs in a second. To solve this we
2979 keep track of the number of jobs started in the last second and
2980 apply a weight to try to guess what a correct load would be.
2981 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2982 Also fixes bug #4693.
2983 (reap_children): Decrease the job count for this second.
2984 (start_job_command): Increase the job count for this second.
2986 * read.c (conditional_line): Expand the text after ifn?def before
2987 checking to see if it's a single word. Fixes bug #7257.
2989 2004-01-09 Paul D. Smith <psmith@gnu.org>
2991 * file.c (print_file): Recurse to print all targets in
2992 double-colon rules. Fixes bug #4518, reported (with patch) by
2993 Andrew Chatham <chatham@google.com>.
2995 2004-01-07 Paul D. Smith <psmith@gnu.org>
2997 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2998 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2999 AC_FUNC_SETVBUF_REVERSED.
3001 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3002 (MAKE Variable): Fix Savannah bug #4898.
3004 * job.c (construct_command_argv_internal): Add "!" to the list of
3005 shell escape chars. POSIX sh allows it to appear before a
3006 command, to negate the exit code. Fixes bug #6404.
3008 * implicit.c (pattern_search): When matching an implicit rule,
3009 remember which dependencies have the ignore_mtime flag set.
3010 Original fix provided in Savannah patch #2349, by Benoit
3011 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3013 2003-11-22 Paul D. Smith <psmith@gnu.org>
3015 * README.W32.template (Outputs): Clarification on -j with
3016 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3019 2003-11-02 Paul D. Smith <psmith@gnu.org>
3021 * function.c (func_if): Strip all the trailing whitespace from the
3022 condition, then don't expand it. Fixed bug # 5798.
3024 * expand.c (recursively_expand_for_file): If we're expanding a
3025 variable with no file context, then use the variable's context.
3028 2003-10-21 Paul D. Smith <psmith@gnu.org>
3030 * main.c (log_working_directory): Add newlines to printf()s.
3032 * README.cvs: Add a note to ignore warnings during autoreconf.
3034 * maintMakefile (po_repo): Set a new URL for PO file updates.
3035 (get-config/config.guess get-config/config.sub): Get these files
3036 from the Savannah config project instead of ftp.gnu.org.
3038 2003-10-05 Paul Eggert <eggert@twinsun.com>
3040 * main.c (main): Avoid potential subscript error if environ has
3043 2003-08-22 Paul D. Smith <psmith@gnu.org>
3045 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3046 systems which don't yet implement the C89 standard :-/.
3048 2003-07-18 Paul D. Smith <psmith@gnu.org>
3050 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3051 [WINDOWS32]: Initialize hash.
3053 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3055 * dir.c (read_dirstream): Provide a workaround for broken versions of
3056 the MinGW dirent structure.
3058 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3060 * w32/include/dirent.h: Add __MINGW32__ filter.
3062 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3064 * make.h: Add global declaration of *make_host.
3065 * main.c (print_usage): Remove local declaration of *make_host.
3066 (print_version): Display "This program built for ..." after Copyright
3069 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3071 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3072 execution of "makeinfo --html make.texi".
3074 2003-04-30 Paul D. Smith <psmith@gnu.org>
3076 * build.template: Make some changes to maybe allow this script to
3077 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3079 * README.OS2.template: New file for OS/2 support. Original
3080 contributed by Andreas Buening.
3081 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3084 2003-04-19 Paul D. Smith <psmith@gnu.org>
3086 Fix bug #1405: allow a target to match multiple pattern-specific
3089 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3090 variable.c, where they've always belonged.
3091 * rule.h: Move the prototypes and struct pattern_var as well.
3092 * variable.c (initialize_file_variables): Invoke
3093 lookup_pattern_var() in a loop, until no more matches are found.
3094 If a match is found, create a new variable set for the target's
3095 pattern variables. Then merge the contents of each matching
3096 pattern variable set into the target's pattern variable set.
3097 (lookup_pattern_var): Change this function to be usable
3098 in a loop. It takes a starting position: if NULL, start at the
3099 beginning; if non-NULL, start with the pattern variable after that
3100 position, and return the next matching pattern.
3101 (create_pattern_var): Create a unique instance of
3102 pattern-specific variables for every definition in the makefile.
3103 Don't combine the same pattern together. This allows us to
3104 process the variable handling properly even when the same pattern
3105 is used multiple times.
3106 (parse_variable_definition): New function: break out the parsing
3107 of a variable definition line from try_variable_definition.
3108 (try_variable_definition): Call parse_variable_definition to
3110 (print_variable_data_base): Print out pattern-specific variables.
3111 * variable.h (struct variable): Remember when a variable is
3112 conditional. Also remember its flavor.
3113 (struct pattern_var): Instead of keeping a variable set, we just
3114 keep a single variable for each pattern.
3115 * read.c (record_target_var): Each pattern variable contains only a
3116 single variable, not a set, so create it properly.
3117 * doc/make.texi (Pattern-specific): Document the new behavior.
3119 2003-04-17 Paul D. Smith <psmith@gnu.org>
3121 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3122 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3123 file/directory naming rules for VMS so I can't tell whether this
3126 2003-04-09 Paul D. Smith <psmith@gnu.org>
3128 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3129 DOS-style pathnames: backslash separators and drive specifiers.
3131 2003-03-28 Paul D. Smith <psmith@gnu.org>
3133 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3134 the intermediate flag on all targets. Fixes bug #2515.
3136 2003-03-24 Paul D. Smith <psmith@gnu.org>
3138 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3139 Upgrade to autoconf 2.57 and automake 1.7.3.
3141 * job.c: More OS/2 changes from Andreas Buening.
3143 * file.c (print_file): Fix variable initialization.
3146 * remake.c (notice_finished_file):
3148 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3149 some calls (like readdir()) return NULL in valid situations
3150 without resetting errno. Fixes bug #2846.
3152 2003-02-25 Paul D. Smith <psmith@gnu.org>
3154 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3156 * job.c (_is_unixy_shell) [OS/2]: New function.
3157 Set default shell to /bin/sh.
3158 (reap_children): Close the job_rfd pipe here since we don't use a
3160 (set_child_handler_action_flags): define this to empty on OS/2.
3161 (start_job_command): Close the jobserver pipe and use
3162 child_execute_job() instead of fork/exec.
3163 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3164 rather than exec'ing, then reconfigure stdin/stdout.
3165 (exec_command): Rewrite to use spawn instead of exec. Return the
3168 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3169 in DOS. Handle the TEMP environment variable as in DOS. Don't
3170 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3171 use -j in DOS mode. Use child_execute_job() instead of
3174 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3177 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3178 prototypes that return values.
3180 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3182 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3183 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3185 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3188 2003-02-24 Paul D. Smith <psmith@gnu.org>
3190 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3191 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3192 (child_execute_job) [VMS]: Handle error status properly.
3193 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3195 * function.c (func_shell): Use EINTRLOOP() while reading from the
3196 subshell pipe (Fixes bug #2502).
3197 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3199 * main.c (main): Ditto.
3201 2003-01-30 Paul D. Smith <psmith@gnu.org>
3203 * read.c (eval): eval() was not fully reentrant, because the
3204 collapsed buffer was static. Change it to be an automatic
3205 variable so that eval() can be invoked recursively.
3207 (eval): Apply patch # 1022: fix memory reference error on long
3208 target-specific variable lines.
3209 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3211 * function.c (check_numeric): Combine the is_numeric() function
3212 into this function, since it's only called from one place.
3213 Constify this function. Have it print the incorrect string in the
3214 error message. Fixes bug #2407.
3215 (strip_whitespace): Constify.
3216 (func_if): Constify.
3217 * expand.c (expand_argument): Constify.
3219 2003-01-29 Paul D. Smith <psmith@gnu.org>
3221 Fix bug # 2169, also reported by other people on various systems.
3223 * make.h: Some systems, such as Solaris and PTX, do not fully
3224 implement POSIX-compliant SA_RESTART functionality; important
3225 system calls like stat() and readdir() can still fail with EINTR
3226 even if SA_RESTART has been set on the signal handler. So,
3227 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3228 EINTR for system calls which return -1 or 0 (NULL), respectively,
3230 Also, remove the old atomic_stat()/atomic_readdir() and
3231 HAVE_BROKEN_RESTART handling.
3233 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3235 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3236 * remake.c (touch_file): Ditto.
3238 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3239 * read.c (construct_include_path): Ditto.
3240 * remake.c (name_mtime): Ditto.
3241 * vpath.c (selective_vpath_search): Ditto.
3242 * dir.c (find_directory): Ditto.
3243 (local_stat): Ditto.
3244 (find_directory): Use ENULLLOOP() to wrap opendir().
3245 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3247 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3248 atomic_readdir() handling.
3250 2003-01-22 Paul D. Smith <psmith@gnu.org>
3252 * function.c (func_call): Fix Bug #1744. If we're inside a
3253 recursive invocation of $(call ...), mask any of the outer
3254 invocation's arguments that aren't used by this one, so that this
3255 invocation doesn't "inherit" them accidentally.
3257 2002-12-05 Paul D. Smith <psmith@gnu.org>
3259 * function.c (subst_expand): Valery Khamenia reported a
3260 pathological performance hit when doing substitutions on very
3261 large values with lots of words: turns out we were invoking
3262 strlen() a ridiculous number of times. Instead of having each
3263 call to sindex() call strlen() again, keep track of how much of
3264 the text we've seen and pass the length to sindex().
3266 2002-11-19 Paul D. Smith <psmith@gnu.org>
3268 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3271 2002-11-16 Paul D. Smith <psmith@gnu.org>
3273 * NMakefile.template (OBJS): Add hash.c object file.
3274 * SMakefile.template (srcs): Ditto.

3276 * build_w32.bat: Ditto.
3278 * Makefile.DOS.template: Remove extra dependencies.
3280 2002-10-25 Paul D. Smith <psmith@gnu.org>
3282 * expand.c (install_variable_buffer): New function. Install a new
3283 variable_buffer context and return the previous one.
3284 (restore_variable_buffer): New function. Free the current
3285 variable_buffer context and put a previously saved one back.
3286 * variable.h: Prototypes for {install,restore}_variable_buffer.
3287 * function.c (func_eval): Push a new variable_buffer context
3288 before we eval, then restore the old one when we're done.
3291 * read.c (install_conditionals): New function. Install a new
3292 conditional context and return the previous one.
3293 (restore_conditionals): New function. Free the current
3294 conditional context and put a previously saved one back.
3295 (eval): Use the {install,restore}_conditionals for "include"
3297 (eval_buffer): Use {install,restore}_conditionals to preserve the
3298 present conditional state before we evaluate the buffer.
3301 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3303 (Recursion): Add a variable index entry for CURDIR.
3305 * README.cvs: Update to appropriate versions.
3306 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3307 don't need to copy loadavg.c: automake is smart enough to create
3308 it for me. Still have a bug in automake related to ansi2knr tho.
3310 2002-10-14 Paul D. Smith <psmith@gnu.org>
3312 * remake.c (notice_finished_file): Only touch targets if they have
3313 at least one command (as per POSIX). Resolve Bug #1418.
3315 * *.c: Convert to using ANSI C-style function definitions.
3316 * Makefile.am: Enable the ansi2knr feature of automake.
3317 * configure.in: ditto.
3319 2002-10-13 Paul D. Smith <psmith@gnu.org>
3321 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3322 for automatic variable values like $^, etc. In the case of very
3323 large lists of prerequisites this causes problems. Instead reuse
3324 a static buffer (resizeable) for each variable.
3326 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3327 target-specific variable definitions. Check for it and set an
3329 (record_target_var): Set the export field to v_export if the
3330 "exported" flag is set.
3331 * doc/make.texi (Target-specific): Document the ability to use
3334 * doc/make.texi: Change the name of the section on automatic
3335 variables from "Automatic" to "Automatic Variables". Added text
3336 clarifying the scope of automatic variables.
3338 2002-10-04 Paul D. Smith <psmith@gnu.org>
3340 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3342 (record_files): Ditto.
3344 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3345 the search for the '=' to only within the enclosing parens.
3347 2002-10-03 Paul D. Smith <psmith@gnu.org>
3349 Version 3.80 released.
3351 * dir.c: Change hash functions to use K&R function definition style.
3352 * function.c: Ditto.
3354 * variable.c: Ditto.
3356 Update to automake 1.7.
3358 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3359 (pdf): Remove this target as automake now provides one.
3361 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3363 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3365 * makefile.com: Updates for GNU make 3.80.
3366 * makefile.vms: Ditto.
3368 2002-09-23 Paul D. Smith <psmith@gnu.org>
3370 * read.c (enum make_word_type): Remove w_comment.
3371 (get_next_mword): Don't treat comment characters as special; where
3372 this function is used we will never see a comment (it's stripped
3373 before we get here) and treating comments specially means that
3374 targets like "foo\#bar" aren't handled properly.
3376 2002-09-18 Paul D. Smith <psmith@gnu.org>
3378 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3380 * read.c (eval): Expansion of arguments to export/unexport was
3381 ignoring all arguments after the first one. Change the algorithm
3382 to expand the whole line once, then parse the results.
3384 2002-09-17 Paul D. Smith <psmith@gnu.org>
3386 Fix Bug #940 (plus another bug I found while looking at this):
3388 * read.c (record_target_var): enter_file() will add a new entry if
3389 it's a double-colon target: we don't want to do that in this
3390 situation. Invoke lookup_file() and only enter_file() if it does
3391 not already exist. If the file we get back is a double-colon then
3392 add this variable to the "root" double-colon target.
3394 * variable.c (initialize_file_variables): If this file is a
3395 double-colon target but is not the "root" target, then initialize
3396 the root and make the root's variable list the parent of our
3399 2002-09-13 Paul D. Smith <psmith@gnu.org>
3401 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3403 * hash.c (round_up_2): Get rid of a warning.
3405 2002-09-12 Paul D. Smith <psmith@gnu.org>
3407 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3408 so it doesn't complain about getloadavg.c.
3410 * commands.c (set_file_variables): Make sure we always alloca() at
3411 least 1 character for the value of $? (for '\0').
3413 2002-09-11 Paul D. Smith <psmith@gnu.org>
3415 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3416 macro to use RESULT instead of the incorrect _RESULT_.
3418 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3419 and atomic_readdir(). We need to #include dirent.h to get this to
3421 * misc.c (atomic_readdir): Fix typos.
3423 2002-09-10 Paul D. Smith <psmith@gnu.org>
3425 * read.c (eval): Expand variable lists given to export and
3426 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3427 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3429 * doc/make.texi (Variables/Recursion): Document this.
3430 (Conditional Syntax): And here.
3432 2002-09-09 Paul D. Smith <psmith@gnu.org>
3434 * configure.in: Check for memmove().
3436 2002-09-07 Paul D. Smith <psmith@gnu.org>
3438 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3439 Michael Sterrett <msterret@coat.com> reports that while it has
3440 SA_RESTART, it does not work properly.
3442 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3443 that invokes stat() and loops to do it again if it returns EINTR.
3444 (atomic_readdir): Ditto, with readdir().
3446 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3447 and readdir() to atomic_stat() and atomic_readdir().
3449 2002-09-04 Paul D. Smith <psmith@gnu.org>
3451 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3452 reports that GNU make sometimes doesn't recognize that targets can
3453 be made, when directories can be created as prerequisites. He
3454 reports that changing the order of predicates in the DEP->changed
3455 flag test so that lookup_file() is always performed, solves this
3458 2002-08-08 Paul D. Smith <psmith@gnu.org>
3460 * configure.in: Require a newer version of gettext.
3462 * misc.c (perror_with_name): Translate the format string (for
3463 right-to-left language support).
3464 (pfatal_with_name): Ditto.
3466 * main.c: Create a static array of strings to store the usage
3467 text. This is done to facilitate translations.
3468 (struct command_switch): Remove argdesc and description fields.
3469 (switches): Remove values for obsolete fields.
3470 (print_usage): Print each element of the usage array.
3472 * hash.c: Change function definitions to be K&R style.
3474 2002-08-02 Paul D. Smith <psmith@gnu.org>
3476 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3477 this one because it's too hard to get right. We'll look at it for
3479 * main.c (main): Don't create the .TARGETS variable.
3480 * variable.c (handle_special_var): Don't handle .TARGETS.
3482 2002-08-01 Paul D. Smith <psmith@gnu.org>
3484 * main.c (switches): Add a new option, -B (--always-make). If
3485 specified, make will rebuild all targets that it encounters even
3486 if they don't appear to be out of date.
3487 (always_make_flag): New flag.
3488 * make.h: Extern always_make_flag.
3489 * remake.c (update_file_1): Check always_make_flag; if it's set we
3490 will always rebuild any target we can, even if none of its
3491 prerequisites are newer.
3494 * doc/make.texi (Shell Function): Make it clear that make
3495 variables marked as "export" are not passed to instances of the
3498 Add new introspection variable .VARIABLES and .TARGETS.
3500 * variable.c (handle_special_var): New function. If the variable
3501 reference passed in is "special" (.VARIABLES or .TARGETS),
3502 calculate the new value if necessary. .VARIABLES is handled here:
3503 walk through the hash of defined variables and construct a value
3504 which is a list of the names. .TARGETS is handled by
3505 build_target_list().
3506 (lookup_variable): Invoke handle_special_var().
3507 * file.c (build_target_list): Walk through the hask of known files
3508 and construct a list of the names of all the ones marked as
3510 * main.c (main): Initialize them to empty (and as simple variables).
3511 * doc/make.texi (Special Variables): Document them.
3512 * NEWS: Mention them.
3514 * variable.h (struct variable): Add a new flag "exportable" which
3515 is true if the variable name is valid for export.
3516 * variable.c (define_variable_in_set): Set "exportable" when a new
3517 variable is defined.
3518 (target_environment): Use the "exportable" flag instead of
3519 re-checking the name here... an efficiency improvement.
3521 2002-07-31 Paul D. Smith <psmith@gnu.org>
3523 * config.h-vms.template: Updates to build on VMS. Thanks to
3524 Brian_Benning@aksteel.com for helping verify the build.
3525 * makefile.com: Build the new hash.c file.
3526 * hash.h: Use strcpmi(), not stricmp(), in the
3527 HAVE_CASE_INSENSITIVE_FS case.
3529 2002-07-30 Paul D. Smith <psmith@gnu.org>
3531 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3532 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3533 Reported by <Brian_Benning@aksteel.com>.
3535 2002-07-10 Paul D. Smith <psmith@gnu.org>
3537 * variable.c (pop_variable_scope): Remove variable made unused by
3538 new hash infrastructure.
3539 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3540 comparisons as well as name comparisons.

3542 * file.c (lookup_file): Remove variables made unused by new hash
3544 * dir.c (directory_contents_hash_2): Missing return of hash value.
3545 (dir_contents_file_exists_p): Remove variables made unused by new
3546 hash infrastructure.
3549 Installed Greg McGary's integration of the hash functions from the
3550 GNU id-utils package:
3552 2002-07-10 Greg McGary <greg@mcgary.org>
3554 * scripts/functions/filter-out: Add literals to to the
3555 pattern space in order to add complexity, and trigger
3556 use of an internal hash table. Fix documentation strings.
3557 * scripts/targets/INTERMEDIATE: Reverse order of files
3558 passed to expected `rm' command.
3560 2002-07-10 Greg McGary <greg@mcgary.org>

3631 (uniquize_deps): Use hash table to efficiently identify duplicates.
3632 (find_char_unquote): Accept two char-constant stop chars, rather
3633 than a string constant, avoiding zillions of calls to strchr.
3634 Tighten inner search loops to test only for desired delimiters.
3636 * variable.c (variable_hash_1, variable_hash_2,
3637 variable_hash_cmp): New functions.
3638 (variable_table): Declare as `struct hash_table'.
3639 (global_variable_set): Remove initialization.
3640 (init_hash_global_variable_set): New function.
3641 (define_variable_in_set): Use new hash table package.
3642 (lookup_variable): Likewise.
3643 (lookup_variable_in_set): Likewise.
3644 (initialize_file_variables): Likewise.
3645 (pop_variable_scope): Likewise.
3646 (create_new_variable_set): Likewise.
3647 (merge_variable_sets): Likewise.
3648 (define_automatic_variables): Likewise.
3649 (target_environment): Likewise.
3650 (print_variable_set): Likewise.
3652 2002-07-10 Paul D. Smith <psmith@gnu.org>
3654 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3655 prerequisite list. A real SysV make will expand the entire
3656 prerequisites list _twice_: we don't do that as it's a big
3657 backward-compatibility problem. We only replace those specific
3660 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3661 references left in the list of prerequisites. Check for .POSIX as
3662 we record targets, so we can disable non-POSIX behavior while
3663 reading makefiles as well as running them.
3664 (eval): Check the prerequisite list to see if we have anything
3665 that looks like a SysV prerequisite variable reference.
3667 2002-07-09 Paul D. Smith <psmith@gnu.org>
3669 * doc/make.texi (Prerequisite Types): Add a new section describing
3670 order-only prerequisites.
3672 * read.c (uniquize_deps): If we have the same file as both a
3673 normal and order-only prereq, get rid of the order-only prereq,
3674 since the normal one supersedes it.
3676 2002-07-08 Paul D. Smith <psmith@gnu.org>
3678 * AUTHORS: Added Greg McGary to the AUTHORS file.
3679 * NEWS: Blurbed order-only prerequisites.
3680 * file.c (print_file): Show order-only deps properly when printing
3683 * maintMakefile: Add "update" targets for wget'ing the latest
3684 versions of various external files. Taken from Makefile.maint in
3687 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3688 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3690 2002-07-07 Paul D. Smith <psmith@gnu.org>
3692 * po/*.po: Remove. We'll use wget to retrieve them at release
3695 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3696 rather than a shell you get an exception. Make sure we look up
3697 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3699 * remake.c (notice_finished_file): Fix handling of -t flag.
3700 Patch provided by Henning Makholm <henning@makholm.net>.
3702 * implicit.c (pattern_search): Some systems apparently run short
3703 of stack space, and using alloca() in this function caused an
3704 overrun. I modified it to use xmalloc() on the two variables
3705 which seemed like they might get large. Fixes Bug #476.
3707 * main.c (print_version): Update copyright notice to conform with
3709 (print_usage): Update help output.
3711 * function.c (func_eval): Create a new make function, $(eval
3712 ...). Expand the arguments, put them into a buffer, then invoke
3713 eval_buffer() on the resulting string.
3714 (func_quote): Create a new function, $(quote VARNAME). Inserts
3715 the value of the variable VARNAME without expanding it any
3718 * read.c (struct ebuffer): Change the linebuffer structure to an
3719 "eval buffer", which can be either a file or a buffer.
3720 (eval_makefile): Move the code in the old read_makefile() which
3721 located a makefile into here: create a struct ebuffer with that
3722 information. Have it invoke the new function eval() with that
3724 (eval_buffer): Create a new function that creates a struct ebuffer
3725 that holds a string buffer instead of a file. Have it invoke
3726 eval() with that ebuffer.
3727 (eval): New function that contains the guts of the old
3728 read_makefile() function: this function parses makefiles. Obtains
3729 data to parse from the provided ebuffer. Some modifications to
3730 make the flow of the function cleaner and clearer. Still could
3731 use some work here...
3732 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3733 contents of the define/endef variable from the ebuffer.
3734 (readstring): Read the next line from a string-style ebuffer.
3735 (readline): Read the next line from an ebuffer. If it's a string
3736 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3739 * dep.h (eval_buffer): Prototype eval_buffer();
3741 * variable.c (do_variable_definition): Make sure that all
3742 non-target-specific variables are registered in the global set.
3743 If we're invoked from an $(eval ...) we might be inside a $(call
3744 ...) or other function which has pushed a variable scope; we still
3745 want to define our variables from evaluated makefile code in the
3748 2002-07-03 Greg McGary <greg@mcgary.org>
3750 * dep.h (struct dep) [ignore_mtime]: New member.
3751 [changed]: convert to a bitfield.
3752 * implicit.c (pattern_search): Zero ignore_mtime.
3753 * main.c (main, handle_non_switch_argument): Likewise.
3754 * rule.c (convert_suffix_rule): Likewise.
3755 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3756 (read_makefile): Parse '|' in prerequisite list.
3757 (uniquize_deps): Consider ignore_mtime when comparing deps.
3758 * remake.c (update_file_1, check_dep): Don't force remake for
3759 dependencies that have d->ignore_mtime.
3760 * commands.c (FILE_LIST_SEPARATOR): New constant.
3761 (set_file_variables): Don't include a
3762 prerequisite in $+, $^ or $? if d->ignore_mtime.
3765 2002-06-18 Paul D. Smith <psmith@gnu.org>
3767 * make.texinfo: Updates for next revision. New date/rev/etc.
3768 Recreate all Info menus. Change license on the manual to the GNU
3769 Free Documentation License. A number of typos.
3770 (Variables Simplify): Don't use "-" before it's defined.
3771 (Automatic Prerequisites): Rewrite the target example to work
3772 properly if the compile fails. Remove incorrect comments about
3773 how "set -e" behaves.
3774 (Text Functions): Move the "word", "wordlist", "words", and
3775 "firstword" functions here, from "File Name Functions".
3776 * make-stds.texi: Update from latest GNU version.
3777 * fdl.texi: (created) Import the latest GNU version.
3779 2002-06-06 Paul D. Smith <psmith@gnu.org>
3781 * variable.c (do_variable_definition): New function: extract the
3782 part of try_variable_definition() that actually sets the value
3783 into a separate function.
3784 (try_variable_definition): Call do_variable_definition() after
3785 parsing the variable definition string.
3786 (define_variable_in_set): Make the name argument const.
3788 * variable.h (enum variable_flavor): Make public.
3789 (do_variable_definition): Create prototype.
3791 * read.c (read_all_makefiles): Create a new built-in variable,
3793 (read_makefile): Add each makefile read in to this variable value.
3795 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3797 * Makefile.DOS.template: Tweak according to changes in the
3798 distribution. Add back the dependencies of *.o files.
3800 * configh.dos.template: Synchronize with config.h.in.
3802 2002-05-09 Paul D. Smith <psmith@gnu.org>
3804 * file.c (file_timestamp_now): Use K&R function declaration.
3806 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3807 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3808 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3809 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3810 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3811 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3812 nlist.n_name is a pointer rather than an array.
3814 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3815 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3816 * configure.in: Use it instead of the old version.
3818 * main.c (main): Prefer setvbuf() to setlinebuf().
3820 2002-05-08 Paul D. Smith <psmith@gnu.org>
3822 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3823 (loadavg_LDADD): Ditto.
3825 2002-04-29 Paul D. Smith <psmith@gnu.org>
3827 * expand.c (recursively_expand_for_file): Rename
3828 recursively_expand() to recursively_expand_for_file() and provide
3829 an extra argument, struct file. If the argument is provided, set
3830 the variable scope to that of the file before expanding.
3831 * variable.h (recursively_expand): Make this a macro that invokes
3832 recursively_expand_for_file() with a NULL file pointer.
3833 * variable.c (target_environment): Call the renamed function and
3834 provide the current file context.
3835 Fixes Debian bug #144306.
3837 2002-04-28 Paul D. Smith <psmith@gnu.org>
3839 Allow $(call ...) user-defined variables to be self-referencing
3840 without throwing an error. Allows implementation of transitive
3841 closures, among other possibly useful things.
3842 Requested by: Philip Guenther <guenther@sendmail.com>
3844 * variable.h (struct variable): Add a new field: exp_count, and
3845 new macros to hold its size and maximum value.
3846 (warn_undefined): Make this a macro.
3847 * variable.c (define_variable_in_set): Initialize it.
3848 * expand.c (recursively_expand): If we detect recursive expansion
3849 of a variable, check the exp_count field. If it's greater than 0
3850 allow the recursion and decrement the count.
3851 (warn_undefined): Remove this (now a macro in variable.h).
3852 * function.c (func_call): Before we expand the user-defined
3853 function, modify its exp_count field to contain the maximum
3854 number of recursive calls we'll allow. After the call, reset it
3857 2002-04-21 Paul D. Smith <psmith@gnu.org>
3859 Modified to use latest autoconf (2.53), automake (1.6.1), and
3860 gettext (0.11.1). We're using gettext's new "external" support,
3861 to avoid including libintl source with GNU make.
3863 * README.cvs: New file. Explain how to build GNU make from CVS.
3865 * configure.in: Modify checking for the system glob library.
3866 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3867 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3868 etc. will manage it correctly). Set an automake conditional
3869 USE_LOCAL_GLOB to decide whether to compile the glob library.
3871 * getloadavg.c (main): Include make.h in the "TEST" program to
3874 * Makefile.am: Remove special rules for loadavg. Replace them
3875 with Automake capabilities for building extra programs.
3877 * signame.c: This file does nothing if the system provide
3878 strsignal(). If not, it implements strsignal(). If the system
3879 doesn't define sys_siglist, then we make our own; otherwise we use
3881 * signame.h: Removed.
3883 * main.c (main): No need to invoke signame_init(). Update copyright.
3885 * ABOUT-NLS: Removed.
3886 * gettext.c: Removed.
3887 * gettext.h: Get a simplified copy from the gettext package.
3889 * i18n/*.po: Moved to po/.
3892 * config/*: Created. Contains package configuration helper files.
3893 * config.guess, config.sub: Moved to config directory.
3895 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3896 Rework to use new-style autoconf features. Use the "external"
3897 mode for gettext. Make the build.sh config file conditional on
3898 whether build.sh.in exists, to avoid autoconf errors.
3899 * acinclude.m4: Removed almost all macros as being obsolete.
3900 Rewrote remaining macros to use AC_DEFINE.
3901 * acconfig.h: Removed.
3903 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3904 conditional to handle customs support. Remove special handling
3907 2002-04-20 Paul D. Smith <psmith@gnu.org>
3909 * function.c (func_call): Don't mark the argument variables $1,
3910 etc. as recursive. They've already been fully expanded so
3911 there's no need to do it again, and doing so strips escaped $'s.
3912 Reported by Sebastian Glita <glseba@yahoo.com>.
3914 * remake.c (notice_finished_file): Walk through double-colon
3915 entries via the prev field, not the next field!
3916 Reported by Greg McGary <greg@mcgary.org>.
3918 * main.c (main): If the user specifies -q and asks for a specific
3919 target which is a makefile, we got an assert. In that case it
3920 turns out we should continue normally instead.
3922 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3924 * i18n/he.po: Installed a new translation.
3926 2002-01-07 Paul D. Smith <psmith@gnu.org>
3928 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3930 2001-12-04 Paul D. Smith <psmith@gnu.org>
3932 * i18n/ja.po: Installed an updated translation.
3934 2001-09-06 Paul Eggert <eggert@twinsun.com>
3936 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3937 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3939 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3941 (main): Get rid of any avoidable limit on stack size.
3943 2001-09-04 Paul D. Smith <psmith@gnu.org>
3945 * i18n/da.po: Installed an updated translation.
3947 2001-08-03 Paul D. Smith <psmith@gnu.org>
3949 * i18n/fr.po: Installed an updated translation.
3950 Resolves Debian bug #106720.
3952 2001-06-13 Paul D. Smith <psmith@gnu.org>
3954 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3957 2001-06-11 Paul D. Smith <psmith@gnu.org>
3959 * i18n/ko.po: Installed a new translation.
3961 2001-05-06 Paul D. Smith <psmith@gnu.org>
3963 Modify the EINTR handling.
3965 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3966 the way in which we manage the file descriptor/signal handler race
3967 trap to be more efficient.
3969 2001-05-06 Paul Eggert <eggert@twinsun.com>
3971 Restart almost all system calls that are interrupted, instead
3972 of worrying about EINTR. The lone exception is the read() for
3975 * configure.in (HAVE_SA_RESTART): New macro.
3976 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3977 * main.c (main): Use SA_RESTART instead of the old,
3978 nonstandard SA_INTERRUPT.
3980 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3981 * main.c (bsd_signal): New function or macro,
3982 if the implementation doesn't supply it.
3983 (The bsd_signal function will be in POSIX 1003.1-200x.)
3984 (HANDLESIG): Remove.
3985 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3987 * make.h (EINTR_SET): Remove.
3988 (SA_RESTART): New macro.
3990 * arscan.c (ar_member_touch): Don't worry about EINTR.
3991 * function.c (func_shell): Likewise.
3992 * job.c (reap_children, free_child, new_job): Likewise.
3993 * main.c (main): Likewise.
3994 * remake.c (touch_file, name_mtime): Likewise.
3996 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3997 if fstat failed with errno!=EINTR, the error was ignored.
3999 * job.c (set_child_handler_action_flags): New function.
4000 (new_job): Use it to temporarily clear the SIGCHLD action flags
4001 while reading the token.
4003 2001-05-02 Paul D. Smith <psmith@gnu.org>
4005 * job.c (start_job_command): Don't add define/endef per-line flags
4006 to the top-level flags setting.
4008 2001-04-03 Paul D. Smith <psmith@gnu.org>
4010 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4011 bit on error, so check for odd return values, not non-0 return
4013 (VMS_get_member_info): Calculate the timezone differences correctly.
4014 Reported by John Fowler <jfowler@nyx.net>.
4017 2001-03-14 Paul D. Smith <psmith@gnu.org>
4019 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4020 value before invoking define_variable().
4021 Reported by John Fowler <jfowler@nyx.net>.
4023 2001-02-07 Paul D. Smith <psmith@gnu.org>
4025 * read.c (record_target_var): If we reset the variable due to a
4026 command-line variable setting overriding it, turn off the "append"
4029 2001-01-17 Paul D. Smith <psmith@gnu.org>
4031 * variable.c (lookup_variable) [VMS]: When getting values from the
4032 environment, allocate enough space for the _value_ plus escapes,
4033 not enough space for the name plus escapes :-/.
4034 Reported by John Fowler <jfowler@nyx.net>.
4036 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4037 warnings that make generates, so it doesn't look like an error.
4038 Reported by Karl Berry <karl@gnu.org>.
4041 Fix for PR/2020: Rework appended target-specific variables. I'm
4042 fairly confident this algorithm is finally correct.
4044 * expand.c (allocated_variable_append): Rewrite. Instead of
4045 expanding each appended variable then adding all the expanded
4046 strings together, we append all the unexpanded values going up
4047 through the variable set contexts, then expand the final result.
4048 This behaves just like non-target-specific appended variable
4049 values, while the old way didn't in various corner cases.
4050 (variable_append): New function: recursively append the unexpanded
4051 value of a variable, walking from the outermost variable scope to
4053 * variable.c (lookup_variable): Remove the code that looked up the
4054 variable set list if the found variable was "append". We don't
4056 (lookup_variable_in_set): Make this non-static so we can use it
4058 (try_variable_definition): Use lookup_variable_in_set() rather
4059 than faking out current_variable_set_list by hand (cleanup).
4060 * variable.h: Add a prototype for the now non-static
4061 lookup_variable_in_set().
4063 2000-11-17 Paul D. Smith <psmith@gnu.org>
4065 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4066 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4067 before throwing a fit.
4069 2000-11-17 Paul D. Smith <psmith@gnu.org>
4071 * read.c (readline): CRLF calculations had a hole, if you hit the
4072 buffer grow scenario just right. Reworked the algorithm to avoid
4073 the need for len or lastlen at all. Problem description with
4074 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4076 2000-10-24 Paul D. Smith <psmith@gnu.org>
4078 * gettext.c (SWAP): Declare this with the prototype, otherwise
4079 some systems don't work (non-32-bit? Reported for Cray T3E).
4080 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4082 2000-10-05 Paul D. Smith <psmith@gnu.org>
4084 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4085 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4087 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4089 2000-09-22 Paul D. Smith <psmith@gnu.org>
4091 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4092 parts of the real gettext.h here, and we expect to really include
4093 the real gettext.h later. If we keep this #define, it's ignored.
4095 2000-09-21 Paul D. Smith <psmith@gnu.org>
4097 * main.c (log_working_directory): Rework the text to use complete
4098 sentences, to make life simpler for the translators.
4100 2000-08-29 Paul D. Smith <psmith@gnu.org>
4102 * file.c (remove_intermediates): Print a debug message before we
4103 remove intermediate files, so the user (if she uses -d) knows
4106 2000-08-21 Paul D. Smith <psmith@gnu.org>
4108 * variable.c (try_variable_definition): Change how we handle
4109 target-specific append variable defns: instead of just setting the
4110 value, expand it as an append _but_ only within the current
4111 target's context. Otherwise we lose all but the last value if the
4112 variable is appended more than once within the current target
4113 context. Fixes PR/1831.
4115 2000-08-16 Paul D. Smith <psmith@gnu.org>
4117 * function.c (func_shell): Nul-terminate the buffer before
4118 printing an exec error message (just in case it's not!).
4119 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4121 2000-07-25 Paul D. Smith <psmith@gnu.org>
4123 * job.c (construct_command_argv_internal): Add "~" to the list of
4124 sh_chars[] which disallow optimizing out the shell call.
4126 2000-07-23 Paul Eggert <eggert@twinsun.com>
4128 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4129 supersedes --disable-nsec-timestamps.
4130 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4131 * README: Remove --disable-nsec-timestamps.
4133 * filedef.h (struct file.low_resolution_time): New member.
4134 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4135 * remake.c (update_file_1):
4136 Avoid spurious rebuilds due to low resolution time stamps,
4137 generalizing the earlier code that applied only to archive members.
4138 (f_mtime): Archive members always have low resolution time stamps.
4140 * configure.in: Remove --disable-nsec-timestamps, as this has
4141 been superseded by .LOW_RESOLUTION_TIME.
4143 2000-07-23 Paul Eggert <eggert@twinsun.com>
4145 * configure.in (enable_nsec_timestamps): Renamed from
4146 make_cv_nsec_timestamps, since enable/disable options
4147 shouldn't be cached.

4152 * file.c (file_timestamp_now):
4153 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4154 so that clock_gettime is not linked unless needed.
4156 * filedef.h (FILE_TIMESTAMP_HI_RES):
4157 Remove definition; "configure" now does this.
4159 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4160 to before high resolution file timestamp check,
4161 since that check now uses uintmax_t.
4162 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4163 high resolution file timestamps.
4164 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4165 so that we don't link in clock_gettime unnecessarily.
4167 2000-07-17 Paul D. Smith <psmith@gnu.org>
4169 * i18n/ja.po: New version of the translation file.
4171 2000-07-07 Paul D. Smith <psmith@gnu.org>
4173 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4174 the offset calculation.
4175 (name_mtime): Replace EINTR test with EINTR_SET macro.
4177 2000-07-07 Paul Eggert <eggert@twinsun.com>
4181 * remake.c (update_file_1):
4182 Avoid spurious rebuilds of archive members due to their
4183 timestamp resolution being only one second.
4184 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4185 the clock's resolution being lower than file timestamps'.
4186 When warning about future timestamps, report only the discrepancy,
4187 not the absolute value of the timestamp and the current time.
4189 * file.c (file_timestamp_now): New arg RESOLUTION.
4190 * filedef.h (file_timestamp_now): Likewise.
4191 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4193 2000-07-05 Paul D. Smith <psmith@gnu.org>
4195 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4196 to listp. Fixes PR/1793.
4198 2000-06-26 Paul Eggert <eggert@twinsun.com>
4200 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4202 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4204 * remake.c (f_mtime): Remove unused var memtime.
4206 2000-06-25 Martin Buchholz <martin@xemacs.org>
4208 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4209 Ran spell-check on make.texinfo.
4211 2000-06-23 Paul D. Smith <psmith@gnu.org>
4213 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4214 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4215 * make.h: Define these macros.
4217 * Version 3.79.1 released.
4219 * configure.in: Add a new option, --disable-nsec-timestamps, to
4220 avoid using sub-second timestamps on systems that support it. It
4221 can lead to problems, e.g. if your makefile relies on "cp -p".
4222 * README.template: Document the issue with "cp -p".
4224 * config.guess, config.sub: Updated.
