550 (mostlyclean-recursive, clean-recursive, distclean-recursive)
551 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
552 (tags-recursive): Allow for more than one subdir in the build
554 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
555 targets. Enter into doc/ to produce the targets.
556 (all-am): $(INFO_DEPS) replaced by info.
558 2009-09-26 Paul Smith <psmith@gnu.org>
560 * read.c (record_files): Use free_ns() to free struct nameseq.
563 * rule.c (freerule): Use free_dep_chain().
565 * read.c (record_files): Free FILENAMES chain for implicit rules.
566 (eval): Static pattern targets go into the string cache.
568 * function.c (string_glob): Free NAME in the nameseq chain.
570 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
572 * implicit.c (pattern_search): Terminate early if we haven't
573 found any rules to try (performance improvement).
575 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
577 * implicit.c (pattern_search): Merge three parallel arrays,
578 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
579 of struct TRYRULE. In the old version the latter two arrays
580 had insufficient length.
582 2009-09-24 Paul Smith <psmith@gnu.org>
584 * implicit.c (pattern_search): Add back support for order-only
585 prerequisites for secondary expansion implicit rules, that were
586 accidentally dropped. If we find a "|", enable order-only mode
587 and set IGNORE_MTIME on all deps that are seen afterward.
588 (pattern_search): Fix memory leaks: for intermediate files where
589 we've already set the file variable and pattern variable sets, be
590 sure to either save or free them as appropriate.
592 2009-09-23 Paul Smith <psmith@gnu.org>
594 Rework the way secondary expansion is stored, for efficiency.
595 This changes secondary expansion so that ONLY WHEN we know we have
596 a possibility of needing secondary expansion, do we defer the
597 secondary expansion. This means more parsing the deps but we use
598 a lot less memory (due to the strcache). Also, this fixes
601 * read.c (eval): Don't parse the dep string here anymore.
602 (record_files): Take the dep argument as an unparsed string. If
603 secondary expansion is enabled AND the prereq string has a '$' in
604 it, then set NEED_2ND_EXPANSION and keep the entire string.
605 Otherwise, parse the dep string here to construct the dep list
606 with the names in the strcache.
608 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
609 duplicate the name string (others are in the strcache).
611 * implicit.c: Remove struct idep and free_idep_chain(): unused.
612 (struct patdeps): New structure to store prereq information.
613 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
614 which prerequisites need expansion, and expand only those.
616 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
617 and enter_prereqs(). split_prereqs() takes a fully-expanded string
618 and splits it into a DEP list, handling order-only prereqs.
619 (enter_prereqs): This function enters a list of DEPs into the file
620 database. If there's a stem defined, expand any pattern chars.
621 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
622 set. Use the above functions.
623 (snap_deps): Only perform second expansion on prereqs that need it,
624 as defined by the NEED_2ND_EXPANSION flag.
625 (print_prereqs): New function to print the prereqs
626 (print_file): Call print_prereqs() rather than print inline.
628 * hash.h (STRING_COMPARE): Take advantage of strcache() by
630 (STRING_N_COMPARE): Ditto.
631 (ISTRING_COMPARE): Ditto.
633 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
634 (parse_file_seq): Return void*
635 * read.c (parse_file_seq): Return void*.
636 (eval): Invoke macroized version of parse_file_seq()
637 * default.c (set_default_suffixes): Ditto.
638 * file.c (split_prereqs): Ditto.
639 * function.c (string_glob): Ditto.
640 * main.c (main): Ditto.
641 * rule.c (install_pattern_rule): Ditto.
643 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
645 2009-09-16 Paul Smith <psmith@gnu.org>
647 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
649 * dep.h: Create alloc_dep() / free_dep() macros.
651 * implicit.c (pattern_search): Take advantage of the new
652 parse_file_seq() to add the directory prefix to each prereq.
654 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
655 all. Avoid reversing chains. Support adding prefixes.
656 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
657 cached/non-cached results.
658 (eval): Remove multi_glob() & invoke new parse_file_seq().
659 * rule.c (install_pattern_rule): Ditto.
660 * main.c (main): Ditto.
661 * implicit.c (pattern_search): Ditto.
662 * function.c (string_glob): Ditto.
663 * file.c (parse_prereqs): Ditto.
664 * default.c (set_default_suffixes): Ditto.
666 * variable.c (parse_variable_definition): Don't run off the end of
667 the string if it ends in whitespace (found with valgrind).
669 * commands.c (set_file_variables): Keep space for all targets in
670 $? if -B is given (found with valgrind).
672 2009-09-15 Paul Smith <psmith@gnu.org>
674 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
675 (xcalloc): Add new function.
676 * make.h: New declarations.
678 * ar.c (ar_glob_match): New calling method for concat().
679 * main.c (main): Ditto.
680 (decode_env_switches): Ditto.
681 * read.c (eval_makefile): Ditto.
682 (tilde_expand): Ditto.
683 (parse_file_seq): Ditto.
684 * variable.c (target_environment): Ditto.
685 (sync_Path_environment): Ditto.
687 * ar.c (ar_glob_match): Use xcalloc().
688 * dir.c (file_impossible): Ditto.
689 * file.c (enter_file): Ditto.
690 * job.c (new_job): Ditto.
691 * read.c (parse_file_seq): Ditto.
692 * vmsfunctions.c (opendir): Ditto.
694 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
696 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
697 inside the loop that looks up environment for PATH.
699 2009-08-31 Eli Zaretskii <eliz@gnu.org>
701 * function.c (windows32_openpipe): Update envp after calling
702 sync_Path_environment.
704 2009-08-02 Paul Smith <psmith@gnu.org>
706 * remake.c (notice_finished_file): Ensure file->cmds is not null
707 before looping through them. Fixes Savannah bug #21824.
709 * doc/make.texi (Wildcard Examples): Clarify when objects is
710 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
711 (Include): Clarify the behavior of -include.
712 Fixes Savannah bug #18963.
714 2009-08-01 Paul Smith <psmith@gnu.org>
716 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
717 etc. come on the command line. Fixes Savannah bug #27093.
719 * expand.c (expand_argument): If the argument is large enough use
720 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
722 * variable.c (do_variable_definition): Avoid using alloca() to
723 hold values, which can be large. Fixes Savannah bug #23960.
725 * job.c (new_job): Use memmove() instead of strcpy() since both
726 pointers are in the same memory block. Fixes Savannah bug #27148.
727 Patch by Petr Machata.
729 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
731 * job.c (construct_command_argv_internal): Add "ulimit" and
732 "unset" to the sh_cmds for Unixy shells.
734 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
737 that set make_cv_sys_gnu_glob, so they are also correctly set
738 when the cache has been populated before.
740 2009-07-04 Eli Zaretskii <eliz@gnu.org>
742 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
743 exist, as realpath(3) does where it's supported.
745 2006-07-04 Eli Zaretskii <eliz@gnu.org>
747 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
748 (abspath): Support systems that define HAVE_DOS_PATHS (have
749 drive letters in their file names). Use IS_PATHSEP instead of a
750 literal '/' comparison. Fixes Savannah bug #26886.
752 2009-06-14 Paul Smith <psmith@gnu.org>
754 * remake.c (update_file_1): Remember the original file we marked
755 as updating, so we can clear that flag again. If we find a target
756 via vpath, FILE might change.
757 (check_dep): Ditto. Fixes Savannah bug #13529.
758 Patch by Reid Madsen <reid.madsen@tek.com>.
760 2009-06-13 Paul Smith <psmith@gnu.org>
762 * doc/make.texi (MAKEFILES Variable): Be explicit that files
763 included by MAKEFILES cannot give default goals.
764 * read.c (eval): If set_default is not set, pass the no-default-goal
765 value when we read included makefiles. Fixes Savannah bug #13401.
767 * ar.c (ar_name): Ensure that targets with empty parens aren't
768 considered archive member references: archive members must have a
769 non-empty "member" string. Fixes Savannah bug #18435.
771 * function.c (string_glob): Rely on multi_glob() to determine
772 whether files exist or not. Remove call to file_exists_p() which
773 is not always correct. Fixes Savannah bug #21231.
774 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
775 then only files that really exist will be returned.
776 * dep.h: Add new argument to multi_glob().
777 * rule.c (install_pattern_rule): Ditto.
778 * read.c (eval): Ditto.
779 * main.c (main): Ditto.
780 * implicit.c (pattern_search): Ditto.
781 * file.c (parse_prereqs): Ditto.
782 * default.c (set_default_suffixes): Ditto.
784 2009-06-09 Paul Smith <psmith@gnu.org>
786 * commands.c (set_file_variables): If always_make_flag is set,
787 always add the prereq to $?. Fixes Savannah bug #17825.
789 * remake.c (update_file_1): When rebuilding deps of FILE, also try
790 to rebuild the deps of all the also_make targets for that file.
791 Fixes Savannah bug #19108.
793 * implicit.c (pattern_search): Undo test for is_target, added by
794 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
795 Rule Search Algorithm". Fixes Savannah bug #17752.
797 * main.c (clean_jobserver): Clear the jobserver_fds options and
798 set job_slots to the default when we clean up.
799 (define_makeflags): Return the new MAKEFLAGS value.
800 (main): Reset MAKEFLAGS in the environment when we re-exec.
801 Fixes Savannah bug #18124.
803 2009-06-08 Paul Smith <psmith@gnu.org>
805 * read.c (eval): Collapse continuations post-semicolon on target-
806 specific variables. Fixes Savannah bug #17521.
808 2009-06-07 Paul Smith <psmith@gnu.org>
810 * job.c (reap_children): For older systems without waitpid() (are
811 there any of these left?) run wait(2) inside EINTRLOOP to handle
812 EINTR errors. Fixes Savannah bug #16401.
814 * (various): Debug message cleanup. Fixes Savannah bug #16469.
816 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
818 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
819 not the end, to catch second expansion $(eval ...) defining new
820 target/prereq relationships during snap_deps.
821 Fixes Savannah bug #24622.
823 * read.c (record_files): The second-expansion "f->updating" hack
824 was not completely correct: if assumed that the target with
825 commands always had prerequisites; if one didn't then the ordering
826 was messed up. Fixed for now to use f->updating to decide whether
827 to preserve the last element in the deps list... but this whole
828 area of constructing and reversing the deps list is too confusing
829 and needs to be reworked. Fixes Savannah bug #21198.
831 2009-06-06 Paul Smith <psmith@gnu.org>
833 * hash.c (hash_insert): Remove useless test for NULL.
834 Fixes Savannah bug #21823.
836 * make.h: Move SET_STACK_SIZE determination to make.h.
837 * main.c (main): New global variable, STACK_LIMIT, holds the
838 original stack limit when make was started.
839 * job.c (start_job_command): Reset the stack limit, if we changed it.
840 Fixes Savannah bug #22010.
842 * remake.c (check_dep): Only set the target's state to not-started
843 if it's not already running. Found this while testing -j10 builds
844 of glibc: various targets were being rebuilt multiple times.
845 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
848 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
849 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
852 2009-06-04 Paul Smith <psmith@gnu.org>
854 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
856 * maintMakefile: Modify access of config and gnulib Savannah
857 modules to use GIT instead of CVS.
859 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
860 Fixes Savannah bug #24655.
862 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
863 this can happen during some invocations of $(eval ...) for example.
864 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
866 2009-06-02 Paul Smith <psmith@gnu.org>
868 * configure.in: Check for fileno()
869 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
870 for the makefile file so invocations of $(shell ...) don't inherit it.
871 Fixes Savannah bug #24277.
873 2009-06-01 Paul Smith <psmith@gnu.org>
875 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
876 expansion was handled incorrectly. Rework the default goal
877 handling to save the variable only. Remove default_goal_file and
879 * read.c (eval): Check default_goal_var, not default_goal_name.
880 * read.c (record_target_var): Don't check default_goal_file here.
882 2009-05-31 Paul Smith <psmith@gnu.org>
884 * main.c (main): Expand the .DEFAULT_GOAL variable before using
885 it, and if the multi_glob() returns nothing (say it expanded to
886 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
888 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
889 $(and ..) to the reference. Fixes Savannah bug #25694.
891 * make.1: Be clear that some recipes will be executed even with -n.
892 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
894 * doc/make.texi (Override Directive): Make more clear how
895 overrides and appends interact.
896 Elucidates part of Savannah bug #26207.
898 * read.c (record_target_var): Don't reset the origin on
899 target-specific variables; try_variable_definition() will handle
900 this correctly. Fixes Savannah bug #26207.
902 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
903 Fixes Savannah bug #25712.
905 * implicit.c (pattern_search): Keep a pointer to the beginning of
906 the filename and save that instead of the constructed pointer.
907 Fixes Savannah bug #26593.
908 Patch by Mark Seaborn <mrs@mythic-beasts.com>
910 2009-05-30 Paul Smith <psmith@gnu.org>
912 * doc/make.texi (Multi-Line): Add a description of the new abilities
913 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
914 "command sequence" vs. "recipe" syntax.
915 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
916 after a define, to create variables with those flavors.
918 2009-05-25 Paul Smith <psmith@gnu.org>
920 Reworked the parser for variable assignments to allow multiple
921 modifiers, and in any order. Also allows variable and
922 prerequisites to be modifier names ('export', 'private', etc.)
924 * NEWS: Add notes about user-visible changes.
926 * read.c (struct vmodifiers): Remember what modifiers were seen.
927 (parse_var_assignment): New function to parse variable assignments.
928 (eval): Call the new function. Handle variable assignments earlier.
930 * variable.c (parse_variable_definition): Only parse; don't create var.
931 (assign_variable_definition): Call parse, then create the var.
933 2009-05-24 Paul Smith <psmith@gnu.org>
935 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
936 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
938 2009-03-14 Eli Zaretskii <eliz@gnu.org>
940 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
941 Fixes Savannah bug #25412.
943 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
944 prototype for xmalloc.
945 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
946 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
947 Loop over an array of extensions, instead of duplicating the same
948 code inline. Use SearchPath followed by CreateFile, instead of
949 the obsolete OpenFile. Fixes Savannah bug #17277.
950 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
951 to `find_file'. Fixes Savannah bug #25662.
953 2009-03-07 Eli Zaretskii <eliz@gnu.org>
955 * function.c (func_shell): Don't close pipedes[1] if it is -1.
956 Fixes Savannah bug #20495.
958 2009-02-28 Ralf Wildenhues <address@hidden>
960 * doc/make.texi (Instead of Execution): Document interaction of
961 -t with phony targets.
963 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
965 Introduce a new keyword "private" which applies to target-specific
966 variables and prevents their values from being inherited.
968 * variable.h (struct variable): Add private_var flag to each variable.
969 Add a flag to specify which list entry switches to the parent target.
970 * variable.c (define_variable_in_set): Initialize private_var flag.

989 2008-09-30 Eli Zaretskii <eliz@gnu.org>
991 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
994 * w32/subproc/build.bat (GCCBuild): Likewise.
996 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
998 * job.c (construct_command_argv_internal): Avoid extra backslash
999 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1002 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1004 * README.W32.template: Remove obsolete text about non-support for
1005 -jN without Unixy shell. Remove obsolete text about not supplying
1006 Visual Studio project files (we do supply them). Modify text to
1007 prefer GCC builds to MSC builds.
1009 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1011 * doc/make.texi (Empty Targets): Fix typo.
1013 2008-03-27 Paul Smith <psmith@gnu.org>
1015 Fix Savannah bug #22379:
1016 * ar.c (ar_glob_match): Zero the allocated structure.
1017 * read.c (parse_file_seq): Ditto.
1019 2008-03-08 Brian Dessent <brian@dessent.net>

1023 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1025 * variable.c (target_environment): Don't use shell_var if its
1026 `value' field is NULL.
1028 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1030 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1032 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1033 (TEXINFOS): Value changed to `doc/make.texi'.
1034 (.SUFFIXES): Use .texi instead of .texinfo.
1035 (make.info, make.dvi): Depend on doc/make.texi.
1036 (.texi.info): New target, instead of ".texinfo.info". Change -I
1037 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1038 (.texi): New target, instead of ".texinfo". Change -I switch to
1039 $(MAKEINFO) to look in doc/. Use --no-split.
1040 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1041 switch to $(MAKEINFO) to look in doc/.
1042 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1043 "*.i[0-9][0-9]" (due to --no-split above).
1044 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1045 (html, make_1.html): New targets.
1046 (.PHONY): Add "html".
1047 (.SUFFIXES): Add .html.
1049 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1051 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1052 HAVE_DECL_SYS_SIGLIST.
1054 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1055 build does not use child_execute_job.
1057 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1058 export the SHELL environment variable to the child.
1060 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1062 * config.h.W32: Include sys/types.h.
1063 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1065 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1066 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is

1079 * remake.c (f_mtime): Print time difference values between 100 and
1080 ULONG_MAX in fixed-point notation rather than in exponention notation.
1082 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1084 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1085 a more complex value than a simple shell: if it's not a default
1086 shell now then expand it and see if is a default shell then.
1088 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1090 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1091 pathnames, with const strings.
1092 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1093 from the template (used for building from CVS, not a dist).
1095 2007-10-10 Paul Smith <psmith@gnu.org>
1097 * make.h: Add a prototype for w32_kill() (change suggested by
1098 Yongwei Wu <wuyongwei@gmail.com>).

1110 Provided by Diego Biurrun <diego@biurrun.de>
1112 2007-09-11 Paul Smith <psmith@gnu.org>
1114 * doc/make.texi (Special Variables): Moved this into the "How to
1115 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1116 (MAKEFILE_LIST) No longer a section; this was added into the
1117 "Special Variables" section.
1118 (Rule Introduction): Reference .RECIPEPREFIX.
1119 (Simple Makefile): Ditto.
1120 (Rule Syntax): Ditto.
1121 (Command Syntax): Ditto.
1122 (Error Messages): Ditto.
1124 2007-09-10 Paul Smith <psmith@gnu.org>
1126 * commands.c (print_commands): Don't print an extra line in the
1127 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1129 * read.c (construct_include_path): Add the full string to the cache; we
1130 were chopping the last char.
1132 * NEWS: Announce the .RECIPEPREFIX special variable.
1133 * variable.c (lookup_special_var): Rename from handle_special_var().
1134 (lookup_variable): Call the new name.
1135 (set_special_var): New function: handle setting of special variables.
1136 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1138 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1139 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1140 * main.c (main): Create the .RECIPEPREFIX special variable.
1141 * read.c (eval): Remove the cmd_prefix characters from the command
1142 scripts here, so they're not stored in the commands array at all,
1143 rather than waiting and stripping them out during command construction.
1144 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1146 2007-08-15 Paul Smith <psmith@gnu.org>
1148 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1149 file has had the section info removed, so add some to make.texi
1150 before we include it.
1152 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1154 * remake.c (check_dep): Reset the target state for intermediate
1155 files. They might have been considered before but not updated

1170 2007-07-13 Paul Smith <psmith@gnu.org>
1172 * file.c (expand_deps): Use variable_buffer as the start of the
1173 buffer, not the original pointer (in case it was reallocated).
1174 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1175 Fixes Savannah bug #20452.
1177 2007-07-04 Paul Smith <psmith@gnu.org>

1200 * job.c (new_job): Add debug info to specify where make found the
1201 command script it is running to build a target.
1202 Fixes Savannah bug #18617.
1204 * default.c (default_suffixes,default_suffix_rules,default_variables):
1205 Add support for Objective C. Fixes Savannah bug #16389.
1206 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1208 * function.c (func_lastword): Initialize p.
1210 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1211 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1212 Dave Korn <dave.korn@artimi.com>
1214 2007-05-08 Paul Smith <psmith@gnu.org>
1216 Fix Savannah bug #19656:
1218 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1220 * make.h: Change all case-insensitive string compares to use
1221 strcasecmp() (from POSIX). If we don't have that but do have one
1222 of the others, define strcasecmp to be one of those instead. If
1223 we don't have any, declare a prototype for our own version.
1225 * misc.c (strcasecmp): Use this if we can't find any native
1226 case-insensitive string comparison function.
1227 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1228 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1230 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1231 strcasecmp() instead of stricmp().
1232 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1233 instead of strcmpi().
1234 * acinclude.m4: Remove the strcasecmp() check from here.
1236 2007-03-21 Paul Smith <psmith@gnu.org>
1238 * configure.in: Don't turn on case-insensitive file system support
1239 if --disable-... is given. Fixes Savannah bug #19348.
1241 2007-03-19 Paul Smith <psmith@gnu.org>
1243 * ALL: Use the strcache for all file name strings, or other
1244 strings which we will never free. The goal is to save memory by
1245 avoiding duplicate copies of strings. However, at the moment this
1246 doesn't save much memory in most situations: due to secondary
1247 expansion we actually save prerequisite lists twice (once before
1248 the secondary expansion, and then again after it's been parsed
1249 into individual file names in the dep list). We will resolve this
1250 in a future change, by doing the parsing up-front for targets
1251 where secondary expansion is not set.
1253 Moving things into the strcache also allows us to use const
1254 pointers in many more places.
1256 2007-01-03 Paul Smith <psmith@gnu.org>
1258 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1259 the function, not just the first. Fixes Savannah bug #18680.
1261 2006-11-18 Paul Smith <psmith@gnu.org>
1263 * strcache.c (strcache_add_len): Don't allocate a new buffer
1264 unless the string is not already nil-terminated. Technically this
1265 is a violation of the standard, since we may be passed an array
1266 that is not long enough to test one past. However, in make this
1267 is never true since we only use nil-terminated strings or
1268 sub-strings thereof.
1270 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1272 * main.c: New global cmd_prefix, defaults to '\t'.
1273 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1276 * dir.c: Constified.
1277 (dir_contents_file_exists_p): Check for an error return from
1278 readdir(), just in case.
1280 * commands.c: Constified.
1281 * default.c: Constified.
1282 * expand.c: Constified.
1283 * function.c: Partial constification.
1284 * variable.c: Partial constification.

1287 * vpath.c: Partial constification.
1288 * w32/pathstuff.c: Partial constification.
1290 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1292 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1293 backslashes and drive letters as absolute.
1295 2006-10-22 Paul Smith <psmith@gnu.org>

1299 2006-10-21 Paul Smith <psmith@gnu.org>
1302 * arscan.c: Constified.
1304 2006-09-30 Paul Smith <psmith@gnu.org>
1306 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1307 point to lastword since the example was updated.
1308 Fixes Savannah bug #16304.
1309 (Secondary Expansion): Correct example description.
1310 Fixes Savannah bug #16468.
1311 (Makefile Contents): Clarify that comments cannot appear within
1312 variable references or function calls.
1313 Fixes Savannah bug #16577.
1314 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1315 Fixes Savannah bug #17701.
1316 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1318 prerequisites. Fixes Savannah bug #17880.
1319 (Rule Syntax): "lise" -> "list"
1320 (Multiple Rules): ... -> @dots{}
1321 (Splitting Lines): ditto.
1323 * remake.c (update_file_1): Prereqs that don't exist should be
1324 considered changed, for the purposes of $?.
1325 Fixes Savannah bug #16051.
1327 * make.1: Remove extraneous "+".
1328 Fixes Savannah bug #16652.

1345 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1346 sh_chars_sh for Windows platforms that emulate Unix.
1348 2006-05-07 Paul D. Smith <psmith@gnu.org>

1364 2006-04-20 Paul D. Smith <psmith@gnu.org>
1366 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1367 that don't have extended grep.
1368 (cvsclean): Use $(PERL) instead of perl.
1370 2006-04-09 Paul D. Smith <psmith@gnu.org>
1372 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1374 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1375 inner-scope variables don't mask outer-scope variables.
1377 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1378 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:

1380 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1381 values from memory allocation functions: they return void* and so
1382 don't need to be cast. Also remove (char *) casts of arguments to

1436 Declare and define sh_chars_sh[].
1438 2006-03-23 Paul D. Smith <psmith@gnu.org>
1440 * configure.in: Look for build.sh.in in $srcdir so it will be
1441 built for remote configurations as well.
1443 * Makefile.am: Make sure to clean up build.sh during distclean.
1444 Fixes Savannah bug #16166.
1446 * misc.c (log_access): Takes a const char *.
1447 * function.c (fold_newlines): Takes an unsigned int *.

1462 make sure I don't forget any).
1464 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1466 (die): Cleanup code was removed from here; call the new function.
1467 (main): If we are re-execing, clean up the jobserver first so we
1468 don't leak file descriptors.

1481 (copy_dep_chain): Copy stem.
1482 (free_dep_chain): Use free_dep.
1483 * read.c (record_files): Store stem in the dependency line.

1498 Fixes Savannah bug #15913.
1500 2006-03-09 Paul Smith <psmith@gnu.org>
1502 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1503 listed non-existent files as changed. Turns out there's a bug in
1504 the Linux kernel builds which means that this change causes
1505 everything to rebuild every time. We will re-introduce this fix
1506 in the next release, to give them time to fix their build system.
1507 Fixes Savannah bug #16002.
1508 Introduces Savannah bug #16051.

1525 2006-02-19 Paul D. Smith <psmith@gnu.org>
1527 * commands.c (set_file_variables): Realloc, not malloc, the static
1528 string values to avoid memory leaks.
1530 * expand.c (recursively_expand_for_file): Only set reading_file to
1531 an initialized value.
1533 * implicit.c (pattern_search): We need to make a copy of the stem
1534 if we get it from an intermediate dep, since those get freed.
1536 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1538 (enter_file) [VMS]: Ditto.

1543 * job.c (construct_command_argv_internal): Fix last change.
1545 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1546 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1547 the calls to _beginthreadex.
1549 * expand.c (recursively_expand_for_file): Initialize `save' to
1550 prevent compiler warnings.
1552 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1554 * job.c (construct_command_argv_internal): Don't create a temporary
1555 script/batch file if we are under -n. Call _setmode to switch the
1556 script file stream to text mode.

1560 * variable.c (merge_variable_set_lists): Don't try to merge the
1561 global_setlist. Not only is this useless, but it can lead to
1562 circularities in the linked list, if global_setlist->next in one
1563 list gets set to point to another list which also ends in
1565 Fixes Savannah bug #15757.

1569 Fix for Savannah bug #106.
1571 * expand.c (expanding_var): Keep track of which variable we're
1572 expanding. If no variable is being expanded, it's the same as
1574 * make.h (expanding_var): Declare it.
1575 * expand.c (recursively_expand_for_file): Set expanding_var to the
1576 current variable we're expanding, unless there's no file info in
1577 it (could happen if it comes from the command line or a default
1578 variable). Restore it before we exit.

1596 * variable.h: Declare it.
1598 * read.c (read_all_makefiles): Makefile names are kept in the
1599 strcache, so there's never any need to alloc/free them.
1602 * main.c (main): Add "archives" to the .FEATURES variable if
1603 archive support is enabled.
1604 * doc/make.texi (Special Variables): Document it.
1606 2006-02-13 Paul D. Smith <psmith@gnu.org>
1608 * implicit.c (pattern_search): Add checking for DOS pathnames to
1609 the pattern rule target LASTSLASH manipulation.
1610 Fixes Savannah bug #11183.

1614 * (ALL FILES): Updated copyright and license notices.
1616 2006-02-10 Paul D. Smith <psmith@gnu.org>
1618 A new internal capability: the string cache is a read-only cache
1619 of strings, with a hash table interface for fast lookup. Nothing
1620 in the cache will ever be freed, so there's no need for reference
1621 counting, etc. This is the beginning of a full solution for
1622 Savannah bug #15182, but for now we only store makefile names here.
1624 * strcache.c: New file. Implement a read-only string cache.
1625 * make.h: Add prototypes for new functions.
1626 * main.c (initialize_global_hash_tables): Initialize the string cache.
1627 (print_data_base): Print string cache stats.
1628 * read.c (eval_makefile): Use the string cache to store makefile
1629 names. Rewrite the string allocation to be sure we free everything.
1631 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1633 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1634 directory time stamp didn't change, except on FAT filesystems.
1635 Suggested by J. David Bryan <jdbryan@acm.org>.
1637 2006-02-09 Paul D. Smith <psmith@gnu.org>
1639 * function.c (func_or): Implement a short-circuiting OR function.
1640 (func_and): Implement a short-circuiting AND function.
1641 (function_table_init): Update the table with the new functions.
1642 * doc/make.texi (Conditional Functions): Changed the "if" section
1643 to one on general conditional functions. Added documentation for
1644 $(and ...) and $(or ...) functions.
1645 * NEWS: Note new $(and ...) and $(or ...) functions.
1647 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1649 * job.h (struct child): Add the dontcare bitfield.
1650 * job.c (new_job): Cache dontcare flag.
1651 * job.c (reap_children): Use cached dontcare flag instead of the
1652 one in struct file. Fixes Savannah bug #15641.
1654 2006-02-06 Paul D. Smith <psmith@gnu.org>
1656 * vpath.c (selective_vpath_search): If the file we find has a
1657 timestamp from -o or -W, use that instead of the real time.
1658 * remake.c (f_mtime): If the mtime is a special token from -o or
1659 -W, don't overwrite it with the real mtime.
1660 Fixes Savannah bug #15341.
1662 Updates from Markus Mauhart <qwe123@chello.at>:
1664 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1666 invalid handle values.
1667 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1668 manage invalid handles; remove them.

1670 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1671 * README.cvs: Updates for building from CVS.
1673 2006-02-05 Paul D. Smith <psmith@gnu.org>
1675 * file.c (enter_file): Keep track of the last double_colon entry,
1676 to avoid walking the list every time we want to add a new one.
1677 Fixes Savannah bug #15533.
1678 * filedef.h (struct file): Add a new LAST pointer.
1680 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1681 the comparison. For 64-bits systems the result of the subtraction
1682 might not fit into an int. Use comparison instead.
1683 Fixes Savannah bug #15534.
1685 * doc/make.texi: Update the chapter on writing commands to reflect
1686 the changes made in 3.81 for backslash/newline and SHELL handling.

1706 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1708 * remake.c (update_goal_chain): Set g->changed instead of
1709 incrementing it, as it is only 8-bit wide, and could overflow if
1710 many commands got started in update_file.
1712 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1714 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1715 MAXIMUM_WAIT_OBJECTS.
1716 (process_wait_for_any_private): Change dimension of handles[]
1717 array to MAXIMUM_WAIT_OBJECTS.

1719 (process_register): Don't register more processes than the
1720 available number of slots.
1721 (process_easy): Don't start new processes if all slots are used up.
1723 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1724 are already more children than sub_proc.c can handle, behave as if
1725 the load were too high.
1726 (start_job_command): Fix a typo in error message when process_easy
1729 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1731 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1732 the shell is not sh.exe.
1734 * job.c (create_batch_file): Renamed from create_batch_filename;
1735 all callers changed. Don't close the temporary file; return its
1736 file descriptor instead. New arg FD allows to return the file
1738 (construct_command_argv_internal): Use _fdopen instead of fopen to
1739 open the batch file.
1741 2006-01-04 Paul D. Smith <psmith@gnu.org>
1743 * readme.vms: Updates for case-insensitive VMS file systems from
1744 Hartmut Becker <Hartmut.Becker@hp.com>.

1764 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1765 disable warnings for MSC.
1766 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1768 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1770 * doc/make.texi (Execution): Add a footnote about changes in
1771 handling of backslash-newline sequences. Mention the differences
1772 on MS-DOS and MS-Windows.
1774 * NEWS: More details about building the MinGW port and a pointer
1775 to README.W32. Fix the section name that describes the new
1776 backward-incompatible processing of backslash-newline sequences.
1777 The special processing of SHELL set to "cmd" is only relevant to
1778 MS-Windows, not MS-DOS.
1780 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1782 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1783 to DWORD, to avoid compiler warnings.
1784 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1785 use %ld in format, to avoid compiler warnings.
1787 * doc/make.texi (Special Targets): Fix a typo.
1788 (Appending): Fix cross-reference to Setting.
1789 (Special Variables, Secondary Expansion, File Name Functions)

1799 * read.c (record_target_var): Initialize variable's export field
1800 with v_default instead of leaving it "initialized" by whatever
1801 garbage happened to be on the heap.
1803 2005-12-12 Paul D. Smith <psmith@gnu.org>
1805 * make.1: Fix some display errors and document all existing options.
1806 Patch by Mike Frysinger <vapier@gentoo.org>.
1808 2005-12-11 Paul D. Smith <psmith@gnu.org>
1810 * implicit.c (pattern_search): If 2nd expansion is not set for
1811 this implicit rule, replace the pattern with the stem directly,
1812 and don't re-expand the variable list. Along with the other
1813 .SECONDEXPANSION changes below, fixes bug #13781.
1815 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1817 * implicit.c (pattern_search): Mark other files that this rule
1818 builds as targets so that they are not treated as intermediates
1819 by the pattern rule search algorithm. Fixes bug #13022.
1821 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1823 * remake.c (notice_finished_file): Propagate the change of
1824 modification time to all the double-colon entries only if

1843 * read.c (record_files): Don't set deps flags if there are no deps.
1844 * maintMakefile: We only need to build the templates when we are
1845 creating a distribution, so don't do it for "all".
1847 2005-10-24 Paul D. Smith <psmith@gnu.org>
1849 Make secondary expansion optional: its enabled by declaring the
1850 special target .SECONDEXPANSION.
1852 * NEWS: Update information on second expansion capabilities.
1853 * doc/make.texi (Secondary Expansion): Document the
1854 .SECONDEXPANSION special target and its behavior.

1856 prerequisite list was found in a static pattern rule.
1857 (free_dep_chain): Declare a prototype.
1858 * file.c (parse_prereqs): New function: break out some complexity
1860 (expand_deps): If we aren't doing second expansion, replace % with
1861 the stem for static pattern rules. Call the new function.
1862 * filedef.h (parse_prereqs): Declare a prototype.
1863 * implicit.c (pattern_search): Initialize the new staticpattern
1865 * main.c (second_expansion): Declare a global variable to remember
1866 if the special target has been seen. Initialize the new
1867 staticpattern field for prerequisites.
1868 * make.h: Extern for second_expansion.
1869 * misc.c (free_dep_chain): New function: frees a struct dep list.
1870 * read.c (read_all_makefiles): Initialize the staticpattern field.
1871 (eval_makefile): Ditto.
1872 (record_files): Check for the .SECONDEXPANSION target and set
1873 second_expansion global if it's found.
1874 Use the new free_dep_chain() instead of doing it by hand.
1875 Set the staticpattern field for prereqs of static pattern targets.
1877 2005-10-16 Paul D. Smith <psmith@gnu.org>
1879 * main.c (main): Set CURDIR to be a file variable instead of a
1880 default, so that values of CURDIR inherited from the environment
1881 won't override the make value.
1883 2005-09-26 Paul D. Smith <psmith@gnu.org>
1885 * job.c (construct_command_argv_internal): If the line is empty
1886 remember to free the temporary argv strings.
1889 2005-09-16 Paul D. Smith <psmith@gnu.org>
1891 * job.c (start_job_command): The noerror flag is a boolean (single
1892 bit); set it appropriately.
1893 Reported by Mark Eichin <eichin@metacarta.com>
1895 2005-08-29 Paul D. Smith <psmith@gnu.org>
1897 * function.c (func_error): On Windows, output from $(info ...)
1898 seems to come in the wrong order. Try to force it with fflush().
1900 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1902 * read.c (record_files): Move code that sets stem for static
1903 pattern rules out of the if (!two_colon) condition so it is
1904 also executed for two-colon rules. Fixes Savannah bug #13881.
1906 2005-08-08 Paul D. Smith <psmith@gnu.org>
1908 * make.h: Don't test that __STDC__ is non-0. Some compilers
1909 (Windows for example) set it to 0 to denote "ISO C + extensions".
1912 2005-08-07 Paul D. Smith <psmith@gnu.org>
1914 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1915 conditional (slightly different version of a fix from Eli).
1917 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1918 If make is running in parallel without -k and two jobs die in a
1919 row, but not too close to each other, then make will quit without
1920 waiting for the rest of the jobs to die.
1922 * main.c (die): Don't reset err before calling reap_children() the
1923 second time: we still want it to be in the error condition.
1924 * job.c (reap_children): Use a static variable, rather than err,
1925 to control whether or not the error message should be printed.
1927 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1929 * w32/subproc/sub_proc.c: Include signal.h.
1930 (process_pipe_io, process_file_io): Pass a pointer to a local
1931 DWORD variable to GetExitCodeProcess. If the exit code is
1932 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1934 * job.c [WINDOWS32]: Include windows.h.
1935 (main_thread) [WINDOWS32]: New global variable.
1936 (reap_children) [WINDOWS32]: Get the handle for the main thread
1937 and store it in main_thread.
1939 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1940 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1941 doing anything else. When we are done, close the main thread
1942 handle and exit with status 130.
1944 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1946 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1949 * main.c (find_and_set_default_shell): If found a DOSish shell,
1950 set sh_found and the value of default_shell, and report the
1951 findings in debug mode.
1953 * job.c (construct_command_argv_internal): Check unixy_shell, not
1954 no_default_sh_exe, to decide whether to use Unixy or DOSish
1957 * README.W32: Update with info about the MinGW build.
1959 * build_w32.bat: Support MinGW.
1961 * w32/subproc/build.bat: Likewise.
1963 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1964 printing DWORD args.
1966 * function.c (windows32_openpipe): Fix format strings for printing
1969 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1971 (start_job_command): Fix format string for printing the result of
1973 (start_job_command) [WINDOWS32]: Do not define.
1974 (exec_command): Fix format string for printing HANDLE args.
1976 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1977 to avoid compiler warnings.
1978 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1979 (Note: some of these fixes were submitted independently by J. Grant)
1981 2005-07-30 J. Grant <jg@jguk.org>
1983 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1984 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1985 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1987 2005-07-15 Paul Smith <psmith@gnu.org>
1989 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1990 we don't have a POSIX shell, then revert to the old
1991 backslash-newline behavior (where they are stripped).
1994 2005-07-08 Paul D. Smith <psmith@gnu.org>
1996 * config.h.W32.template: Reorder to match the standard config.h,
1997 for easier comparisons.
1998 From J. Grant <jg@jguk.org>
2000 * maintMakefile: Remove .dep_segment before overwriting it, in
2001 case it's not writable or noclobber is set.
2002 * expand.c (variable_expand_string): Cast result of pointer
2003 arithmetic to avoid a warning.
2004 * main.c (switches): Add full-fledged final initializer.
2006 2005-07-06 Paul D. Smith <psmith@gnu.org>
2008 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2009 * signame.c (strsignal): If we found _sys_siglist[] or
2010 __sys_siglist[] use those instead of sys_siglist[].
2011 From Albert Chin <china@thewrittenword.com>
2013 2005-07-04 Paul D. Smith <psmith@gnu.org>
2015 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2016 globfree(); set up to use the GNU versions.
2017 From Martin Zinser <zinser@zinser.no-ip.info>
2019 2005-07-03 Paul D. Smith <psmith@gnu.org>
2021 From J. Grant <jg@jguk.org>:

2027 * w32/subproc/build.bat: Ditto.
2029 2005-06-28 Paul D. Smith <psmith@gnu.org>
2031 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2032 declaration was checked but not present.
2034 2005-06-27 Paul D. Smith <psmith@gnu.org>
2036 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2037 to unsigned long. Fixes Savannah bug #13550.
2039 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2040 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2041 Fixes Savannah bug #13551.
2043 2005-06-26 Paul D. Smith <psmith@gnu.org>
2045 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2046 it if ANSI_STRING is not set.
2048 2005-06-25 Paul D. Smith <psmith@gnu.org>
2050 * read.c (eval): If no filenames are passed to any of the
2051 "include" variants, don't print an error.
2052 * doc/make.texi (Include): Document this.
2053 Fixes Savannah bug #1761.
2055 * job.c (construct_command_argv_internal): Sanitize handling of
2056 backslash/newline pairs according to POSIX: that is, keep the
2057 backslash-newline in the command script, but remove a following
2058 TAB character, if present. In the fast path, make sure that the
2059 behavior matches what the shell would do both inside and outside
2060 of quotes. In the slow path, quote the backslash and put a
2061 literal newline in the string.
2062 Fixes Savannah bug #1332.
2063 * doc/make.texi (Execution): Document the new behavior and give
2065 * NEWS: Make a note of the new behavior.
2067 * make.h [WINDOWS32]: #include <direct.h>.
2068 Fixes Savannah bug #13478.
2070 * remake.c (name_mtime): If the stat() of a file fails and the -L
2071 option was given and the file is a symlink, take the best mtime of
2072 the symlink we can get as the mtime of the file and don't fail.
2073 Fixes Savannah bug #13280.
2075 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2076 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2077 inside a variable reference. Make this function static as it's
2079 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2080 parsing an unexpanded line looking for semicolons.
2081 Fixes Savannah bug #1454.
2082 * misc.c (remove_comments): Move this to read.c and make it static
2083 as it's only used there. Call find_char_unquote() with new arg.
2084 * make.h: Remove prototypes for find_char_unquote() and
2085 remove_comments() since they're static now.
2087 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2088 its export flag and obtain its value. When we need to re-exec,
2089 increment the value and add it into the environment.
2090 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2091 * NEWS: Mention MAKE_RESTARTS.
2092 * main.c (always_make_set): New variable. Change the -B option to
2093 set this one instead.
2094 (main): When checking makefiles, only set always_make_flag if
2095 always_make_set is set AND the restarts flag is 0. When building
2096 normal targets, set it IFF always_make_set is set.
2097 (main): Avoid infinite recursion with -W, too: only set what-if
2098 files to NEW before we check makefiles if we've never restarted
2099 before. If we have restarted, set what-if files to NEW _after_ we

2105 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2106 in the prerequisites list.
2108 2005-06-12 Paul D. Smith <psmith@gnu.org>
2110 Fix Savannah bug # 1328.
2112 * configure.in: Check for atexit().
2113 * misc.c (close_stdout): Test stdout to see if writes to it have
2114 failed. If so, be sure to exit with a non-0 error code. Based on
2115 code found in gnulib.
2116 * make.h: Prototype.
2117 * main.c (main): Install close_stdout() with atexit().
2119 2005-06-10 Paul D. Smith <psmith@gnu.org>
2121 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2123 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2124 headers; make vmsWaitForChildren() static; extern vmsify().
2125 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2126 Don't create child_execute_job() here (it's in vmsjobs.c).
2127 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2129 2005-06-09 Paul D. Smith <psmith@gnu.org>
2131 * variable.c (push_new_variable_scope): File variables point
2132 directly to the global_setlist variable. So, inserting a new
2133 scope in front of that has no effect on those variables: they
2134 don't go through current_variable_set_list. If we're pushing a
2135 scope and the current scope is global, push it "the other way" so
2136 that the new setlist is in the global_setlist variable, and
2137 next points to a new setlist with the global variable set.
2138 (pop_variable_scope): Properly undo a push with the new
2140 Fixes Savannah bug #11913.
2142 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2144 * job.c (reap_children): Don't die of the command failed but
2145 the dontcare flag is set. Fixes Savannah bug #13216.
2147 * implicit.c (pattern_search): When creating a target from
2148 an implicit rule match, lookup pattern target and set precious
2149 flag in a newly created target. Fixes Savannah bug #13218.
2151 2005-05-13 Paul D. Smith <psmith@gnu.org>
2153 Implement "if... else if... endif" syntax.
2155 * read.c (eval): Push all checks for conditional words ("ifeq",
2156 "else", etc.) down into the conditional_line() function.
2157 (conditional_line): Rework to allow "else if..." clause. New
2158 return value -2 for lines which are not conditionals. The
2159 ignoring flag can now also be 2, which means "already parsed a
2160 true branch". If that value is seen no other branch of this
2161 conditional can be considered true. In the else parsing if there
2162 is extra text after the else, invoke conditional_line()
2163 recursively to see if it's another conditional. If not, it's an
2164 error. If so, raise the conditional value to this level instead
2165 of creating a new conditional nesting level. Special check for
2166 "else" and "endif", which aren't allowed on the "else" line.
2167 * doc/make.texi (Conditional Syntax): Document the new syntax.
2169 2005-05-09 Paul D. Smith <psmith@gnu.org>
2171 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2172 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2173 recurses to the w32 directory, even on non-Windows systems. Use
2174 the method suggested in the automake manual.
2175 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2176 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2178 2005-05-07 Paul D. Smith <psmith@gnu.org>
2180 * main.c (die): If we're dying with a fatal error (not that a
2181 command has failed), write back any leftover tokens before we go.
2183 * job.c (set_child_handler_action_flags): If there are jobs
2184 waiting for the load to go down, set an alarm to go off in 1
2185 second. This allows us to wake up from a potentially long-lasting
2186 read() and start a new job if the load has gone down. Turn it off
2188 (job_noop): Dummy signal handler function.
2189 (new_job): Invoke it with the new semantics.
2191 * docs/make.texi: Document secondary expansion. Various cleanups
2194 2005-05-03 Paul D. Smith <psmith@gnu.org>
2196 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2197 the targets which are to ultimately be made are called "goals";
2198 see the GNU make manual. Also, MAKECMDGOALS, etc.
2200 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2201 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2202 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2204 2005-05-02 Paul D. Smith <psmith@gnu.org>
2206 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2207 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2208 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2209 functions to vmsjobs.c. #include it into jobs.c.
2211 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2212 jobserver tokens. I found that this happens when an exported
2213 recursive variable contains a $(shell ...) function reference: in
2214 this situation we could "forget" to write back a token.
2216 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2217 we have. It's not reliable to depend on the number of children in
2218 our linked list so keep a separate count.
2219 (new_job): Check jobserver_tokens rather than children &&
2220 waiting_jobs. Increment jobserver_tokens when we get one.
2221 (free_child): If jobserver_tokens is 0, internal error. If it's
2222 >1, write a token back to the jobserver pipe (we don't write a
2223 token for the "free" job). Decrement jobserver_tokens.
2225 * main.c: Add variable master_job_slots.
2226 (main): Set it to hold the number of jobs requested if we're the
2227 master process, when using the jobserver.
2228 (die): Sanity checks: first test jobserver_tokens to make sure
2229 this process isn't holding any tokens we didn't write back.
2230 Second, if master_job_slots is set count the tokens left in the
2231 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2233 2005-04-24 Paul D. Smith <psmith@gnu.org>
2235 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2236 with -l# can lose jobserver tokens, because waiting jobs are not
2237 consulted properly when checking for the "free" token.
2239 * job.c (free_child): Count waiting_jobs as having tokens.
2240 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2241 handle jobs waiting for the load to drop.
2243 2005-04-23 Paul D. Smith <psmith@gnu.org>
2245 * main.c (main): Be careful to not core if a variable setting in
2246 the environment doesn't contain an '='. This is illegal but can
2247 happen in broken setups.
2248 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2250 2005-04-12 Paul D. Smith <psmith@gnu.org>
2252 The second expansion feature causes significant slowdown. Timing
2253 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2254 read the makefile before the feature, to 11+s to do the same
2255 operations after the feature. Additionally, memory usage
2256 increased drastically. To fix this I added some intelligence that
2257 avoids the overhead of the second expansion unless it's required.
2259 * dep.h: Add a new boolean field, need_2nd_expansion.
2261 * read.c (eval): When creating the struct dep for the target,
2262 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2263 (record_files): If there's a "%" in a static pattern rule, it gets
2264 converted to "$*" so set need_2nd_expansion to 1.
2266 * file.c (expand_deps): Rework to be more efficient. Only perform
2267 initialize_file_variables(), set_file_variables(), and
2268 variable_expand_for_file() if the need_2nd_expansion is set.
2270 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2271 (pattern_search): Ditto.
2272 * main.c (handle_non_switch_argument): Ditto.
2274 * read.c (read_all_makefiles): Ditto.
2275 (eval_makefile): Ditto.
2277 2005-04-07 Paul D. Smith <psmith@gnu.org>
2279 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2280 * variable.c (sync_Path_environment): Ditto.
2281 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2283 * main.c (main): Define the .FEATURES variable.
2284 * NEWS: Announce .FEATURES.
2285 * doc/make.texi (Special Variables): Document .FEATURES.
2287 * remake.c (check_dep): If a file is .PHONY, update it even if
2288 it's marked intermediate. Fixes Savannah bug #12331.
2290 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2292 * file.c (expand_deps): Factor out the second expansion and
2293 prerequisite line parsing logic from snap_deps().
2295 * file.c (snap_deps): Use expand_deps(). Expand and parse
2296 prerequisites of the .SUFFIXES special target first. Fixes
2297 Savannah bug #12320.
2299 2005-03-13 Paul D. Smith <psmith@gnu.org>
2301 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2304 2005-03-11 Paul D. Smith <psmith@gnu.org>
2306 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2307 available, not undefined (from Earnie Boyd).
2309 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2311 * implicit.c (pattern_search): Mark an intermediate target as
2312 precious if it happened to be a prerequisite of some (other)
2313 target. Fixes Savannah bug #12267.
2315 2005-03-09 Paul D. Smith <psmith@gnu.org>
2317 * read.c (eval_makefile): Add alloca(0).
2318 (eval_buffer): Ditto.
2320 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2322 * main.c (main): Use o_file instead of o_default when defining
2323 the .DEFAULT_TARGET special variable.
2324 * read.c (eval): Use define_variable_global() instead of
2325 define_variable() when setting new value for the .DEFAULT_TARGET
2326 special variable. Fixes Savannah bug #12266.
2328 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2330 * imlicit.c (pattern_search): Mark files for which an implicit
2331 rule has been found as targets. Fixes Savannah bug #12202.
2333 2005-03-04 Paul D. Smith <psmith@gnu.org>
2336 * doc/make.texi (Automatic Variables): Document $|.
2338 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2340 * read.c (record_files): Instead of substituting % with
2341 actual stem value in dependency list replace it with $*.
2342 This fixes stem triple expansion bug.
2344 * implicit.c (pattern_search): Copy stem to a separate
2345 buffer and make it a properly terminated string. Assign
2346 this buffer instead of STEM (which is not terminated) to
2347 f->stem. Instead of substituting % with actual stem value
2348 in dependency list replace it with $*. This fixes stem
2349 triple expansion bug.
2351 2005-03-01 Paul D. Smith <psmith@gnu.org>
2353 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2354 on Windows, as it takes a handle not a pid. Just exit.
2355 Fix from patch #3679, provided by Alessandro Vesely.
2357 * configure.in: Update check for sys_siglist[] from autoconf manual.
2358 * signame.c (strsignal): Update to use the new autoconf macro.
2360 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2362 * read.c (record_files): Add a check for the list of prerequisites
2363 of a static pattern rule being empty. Fixes Savannah bug #12180.
2365 2005-02-28 Paul D. Smith <psmith@gnu.org>
2367 * doc/make.texi (Text Functions): Update docs to allow the end
2368 ordinal for $(wordlist ...) to be 0.
2369 * function.c (func_wordlist): Fail if the start ordinal for
2370 $(wordlist ...) is <1. Matches documentation.
2371 Resolves Savannah support request #103195.
2373 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2374 previously we were stopping when !-q, exactly the opposite. This
2375 has been wrong since version 1.34, in 1994!
2376 (update_file): If we got an error don't break out to run more
2377 double-colon rules: just return immediately.
2378 Fixes Savannah bug #7144.
2380 2005-02-27 Paul D. Smith <psmith@gnu.org>
2382 * misc.c (end_of_token): Make argument const.
2383 * make.h: Update prototype.
2385 * function.c (abspath, func_realpath, func_abspath): Use
2386 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2387 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2388 * read.c (record_files): Ditto.
2389 * variable.c (do_variable_definition): Ditto.
2391 * function.c (func_error): Create a new function $(info ...) that
2392 simply prints the message to stdout with no extras.
2393 (function_table_init): Add new function to the table.
2394 * NEWS: Add $(info ...) reference.
2395 * doc/make.texi (Make Control Functions): Document it.
2397 New feature: if the system supports symbolic links, and the user
2398 provides the -L/--check-symlink-time flag, then use the latest
2399 mtime between the symlink(s) and the target file.
2401 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2402 readlink(). If both are available, define MAKE_SYMLINKS.
2403 * main.c: New variable: check_symlink_flag.
2404 (usage): Add a line for -L/--check-symlink-times to the help string.
2405 (switches): Add -L/--check-symlink-times command line argument.
2406 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2407 print a warning and disable it again.
2408 * make.h: Declare check_symlink_flag.
2409 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2410 if the file is a symlink then check each link in the chain and
2411 choose the NEWEST mtime we find as the mtime for the file. The
2412 newest mtime might be the file itself!
2413 * NEWS: Add information about this new feature.
2414 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2416 Avoid core dumps described in Savannah bug # 12124:
2418 * file.c: New variable snapped_deps remember whether we've run
2420 (snap_deps): Set it.
2421 * filedef.h: Extern it.
2422 * read.c (record_files): Check snapped_deps; if it's set then
2423 we're trying to eval a new target/prerequisite relationship from
2424 within a command script, which we don't support. Fatal.
2426 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2428 Implementation of the .DEFAULT_TARGET special variable.
2430 * read.c (eval): If necessary, update default_target_name when
2432 * read.c (record_files): Update default_target_file if
2433 default_target_name has changed.
2434 * main.c (default_target_name): Define.
2435 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2436 default_target_name is set use default_target_file as a root
2438 * filedef.h (default_target_name): Declare.
2439 * dep.h (free_dep_chain):
2440 * misc.c (free_dep_chain): Change to operate on struct nameseq
2441 and change name to free_ns_chain.
2442 * file.c (snap_deps): Update to use free_ns_chain.
2444 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2446 Implementation of the second expansion in explicit rules,
2447 static pattern rules and implicit rules.
2449 * read.c (eval): Refrain from chopping up rule's dependencies.
2450 Store them in a struct dep as a single dependency line. Remove
2451 the code that implements SySV-style automatic variables.
2453 * read.c (record_files): Adjust the code that handles static
2454 pattern rules to expand all percents instead of only the first
2455 one. Reverse the order in which dependencies are stored so that
2456 when the second expansion reverses them again they appear in
2457 the makefile order (with some exceptions, see comments in
2458 the code). Remove the code that implements SySV-style automatic
2461 * file.c (snap_deps): Implement the second expansion and chopping
2462 of dependency lines for explicit rules.
2464 * implicit.c (struct idep): Define an auxiliary data type to hold
2465 implicit rule's dependencies after stem substitution and
2468 * implicit.c (free_idep_chain): Implement.
2470 * implicit.c (get_next_word): Implement helper function for
2471 parsing implicit rule's dependency lines into words taking
2472 into account variable expansion requests. Used in the stem
2475 * implicit.c (pattern_search): Implement the second expansion
2476 for implicit rules. Also fixes bug #12091.
2478 * commands.h (set_file_variables): Declare.
2479 * commands.c (set_file_variables): Remove static specifier.
2481 * dep.h (free_dep_chain): Declare.
2482 * misc.c (free_dep_chain): Implement.
2484 * variable.h (variable_expand_for_file): Declare.
2485 * expand.c (variable_expand_for_file): Remove static specifier.
2487 * make.h (strip_whitespace): Declare.
2488 * function.c (strip_whitespace): Remove static specifier.
2490 2005-02-26 Paul D. Smith <psmith@gnu.org>
2492 * main.c (main): Check for ferror() when reading makefiles from stdin.
2493 Apparently some shells in Windows don't close pipes properly and
2496 2005-02-24 Jonathan Grant <jg@jguk.org>
2498 * configure.in: Add MinGW configuration options, and extra w32 code
2500 * Makefile.am: Add MinGW configuration options, and extra w32 code
2502 * main.c: Determine correct program string (after last \ without .exe).
2503 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2505 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2506 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2507 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2508 environment support.
2510 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2512 * function.c (func_shell): When initializing error_prefix, check
2513 that reading file name is not null. This fixes long-standing
2514 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2516 2005-02-09 Paul D. Smith <psmith@gnu.org>
2518 * maintMakefile: Update the CVS download URL to simplify them.
2519 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2520 downloading the .texi files from Savannah now.
2522 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2524 * main.c (handle_non_switch_argument): Only add variables to
2525 command_variables if they're not already there: duplicate settings
2526 waste space and can be confusing to read.
2528 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2529 this header is never included by non-WINDOWS32 code, and it
2530 requires <config.h> to define which isn't always included first.
2532 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2533 testing MINGW32 versions.
2535 * main.c (log_working_directory): flush stdout to be sure the WD
2536 change is printed before any stderr messages show up.
2538 2005-02-01 Paul D. Smith <psmith@gnu.org>
2540 * maintMakefile (po_repo): Update the GNU translation site URL.
2542 2004-12-01 Paul D. Smith <psmith@gnu.org>
2544 * main.c (main): Change char* env_shell to struct variable shell_var.
2545 * variable.c (target_environment): Use new shell_var.
2547 2004-11-30 Paul D. Smith <psmith@gnu.org>
2549 * configure.in: The old way we avoided creating build.sh from
2550 build.sh.in before build.sh.in exists doesn't work anymore; we
2551 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2552 the help!). This also keeps automake from complaining.
2553 * Makefile.am (README): Add a dummy target so automake won't
2554 complain that this file doesn't exist when we checkout from CVS.
2555 * maintMakefile (.dep_segment): Rewrite this rule since newer
2556 versions of automake don't provide DEP_FILES.
2558 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2560 Implementation of `realpath' and `abspath' built-in functions.
2562 * configure.in: Check for realpath.
2563 * function.c (abspath): Return an absolute file name that does
2564 not contain any `.' or `..' components, nor repeated `/'.
2565 * function.c (func_abspath): For each name call abspath.
2566 * function.c (func_realpath): For each name call realpath
2567 from libc or delegate to abspath if realpath is not available.
2568 * doc/make.texi (Functions for File Names): Document new functions.
2569 * doc/make.texi (Quick Reference): Ditto.
2571 2004-11-28 Paul D. Smith <psmith@gnu.org>
2573 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2574 arguments. Fixes bug #10252.
2576 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2578 * main.c (main): Set SHELL to v_noexport by default. Remember the
2579 original environment setting of SHELL in the env_shell variable.
2580 * main.h: Export new env_shell variable.
2581 * variable.c (target_environment): If we find a v_noexport
2582 variable for SHELL, add a SHELL variable with the env_shell value.
2583 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2584 * doc/make.texi (Variables/Recursion): Ditto.
2586 2004-11-28 Paul D. Smith <psmith@gnu.org>
2588 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2589 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2590 Patch by Alessandro Vesely.
2592 2004-11-12 Paul D. Smith <psmith@gnu.org>
2594 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2595 the command line if it's inside a string.
2596 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2598 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2600 * function.c (func_lastword): New function: return last word
2601 from the list of words.
2602 * doc/make.texi: Document $(lastword ). Fix broken links in
2603 Quick Reference section.
2605 2004-10-06 Paul D. Smith <psmith@gnu.org>
2607 Apply patch from Alessandro Vesely, provided with bug # 9748.
2608 Fix use of tmpnam() to work with Borland C.
2610 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2611 construction of a temporary filename, and call new function
2612 create_batch_filename().
2613 (create_batch_filename) [WINDOWS32]: New function to create a
2616 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2618 * read.c (record_target_var): Expand simple pattern-specific
2620 * variable.c (initialize_file_variables): Do not expand simple
2621 pattern-specific variable.
2623 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2625 * remake.c (update_file_1): When rebuilding makefiles inherit
2626 dontcare flag from a target that triggered update.
2628 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2630 * variable.c (initialize_file_variables): Mark pattern-specific
2631 variable as a per-target and copy export status.
2633 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2635 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2637 * implicit.c (pattern_search): When considering an implicit rule's
2638 prerequisite check that it is actually a target rather then
2639 just an entry in the file hashtable.
2641 2004-09-21 Paul D. Smith <psmith@gnu.org>
2643 * read.c (readstring): Fix some logic errors in backslash handling.
2644 (eval): Remove some unnecessary processing in buffer handling.
2645 (record_target_var): Assert that parse_variable_definition() succeeded.
2646 Reported by: Markus Mauhart <qwe123@chello.at>.
2648 * misc.c: Removed the sindex() function. All instances of this
2649 function were trivially replaceable by the standard strstr()
2650 function, and that function will always have better (or certainly
2651 no worse) performance than the very simple-minded algorithm
2652 sindex() used. This can matter with complex makefiles.
2653 * make.h: Remove the prototype for sindex().
2654 * function.c (subst_expand): Convert sindex() call to strstr().
2655 This means we no longer need to track the TLEN value so remove that.
2656 (func_findstring): Convert sindex() to strstr().
2657 * commands.c (chop_commands): Convert sindex() calls to strstr().
2658 Suggested by: Markus Mauhart <qwe123@chello.at>.
2660 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2661 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2662 If SHELL is set to CMD.EXE then assume it's batch-mode and
2663 non-unixy. I wrote the code differently from the patch, though,
2664 to make it safer. This also resolves bug #9174.
2666 2004-09-20 Paul D. Smith <psmith@gnu.org>
2668 * expand.c (variable_expand_string): Modify to invoke
2669 patsubst_expand() instead of subst_expand(); the latter didn't
2670 handle suffix patterns correctly.
2671 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2672 was used only from variable_expand_string() and is no longer used
2674 (func_subst): Ditto, on call to subst_expand().
2675 (patsubst_expand): Require the percent pointers to point to the
2676 character after the %, not to the % itself.
2677 * read.c (record_files): New call criteria for patsubst_expand().
2678 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2679 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2681 2004-09-19 Paul D. Smith <psmith@gnu.org>
2683 * function.c (subst_expand): Fix a check in by_word: look for a
2684 previous blank if we're beyond the beginning of the string, not
2685 the beginning of the word.
2686 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2688 2004-05-16 Paul D. Smith <psmith@gnu.org>
2690 * remake.c (update_goal_chain): Change the argument specifying
2691 whether we're rebuilding makefiles to be a global variable,
2692 REBUILDING_MAKEFILES.
2693 (complain): Extract the code that complains about no rules to make
2694 a target into a separate function.
2695 (update_file_1): If we tried to rebuild a file during the makefile
2696 rebuild phase and it was dontcare, then no message was printed.
2697 If we then try to build the same file during the normal build,
2698 print a message this time.
2699 (remake_file): Don't complain about un-remake-able files when
2700 we're rebuilding makefiles.
2702 2004-05-11 Paul D. Smith <psmith@gnu.org>
2704 * job.c (construct_command_argv_internal): OS/2 patches from
2705 Andreas Buening <andreas.buening@nexgo.de>.
2707 2004-05-10 Paul D. Smith <psmith@gnu.org>
2709 * remake.c (update_file): Don't walk the double-colon chain unless
2710 this is a double-colon rule. Fix suggested by Boris Kolpackov
2711 <boris@kolpackov.net>.
2713 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2714 * readme.vms: New section describing OpenVMS support and issues.
2715 * default.c (default_variables): Add support for IA64.
2716 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2717 without some privilege aborts make with the error
2718 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2719 pressing Ctrl+Y and the input device is no terminal. The change
2720 catches this error and just continues.
2722 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2724 2004-04-25 Paul D. Smith <psmith@gnu.org>
2726 * commands.c (set_file_variables): Set $< properly in the face of
2727 order-only prerequisites.
2728 Patch from Boris Kolpackov <boris@kolpackov.net>
2730 2004-04-21 Bob Byrnes <byrnes@curl.com>
2732 * main.c (main): Notice failures to remake makefiles.
2734 2004-03-28 Paul D. Smith <psmith@gnu.org>
2736 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2738 * job.c: No default shell for RISC OS.
2739 (load_too_high): Hard-code the return to 1.
2740 (construct_command_argv_internal): No sh_chars or sh_cmds.
2741 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2743 2004-03-20 Paul D. Smith <psmith@gnu.org>
2745 * variable.c (do_variable_definition): Don't append from the
2746 global set if a previous non-appending target-specific variable
2747 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2750 * expand.c (reference_variable): Don't give up on variables with
2751 no value that have the target-specific append flag set: they might
2752 have a value after all. Reported by Oliver Schmidt
2753 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2754 <nikulin@dx1cmd.inp.nsk.su>.
2756 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2757 refer to absolute pathnames in directories that don't exist: some
2758 portion of the makefile could create those directories before we
2759 match the pattern. Fixes bugs #775 and #108.
2761 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2763 * main.c (main): Free makefile_mtimes if we have any.
2764 * README.W32.template: Update documentation for the current status
2765 of the MS-Windows port.
2766 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2767 environment variable is sometimes already defined which causes the
2769 * main.c (debug_signal_handler): Only define this function if
2770 SIGUSR1 is available.
2772 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2774 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2775 * README.OS2.template: Documentation updates.
2776 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2777 link line for safety.
2778 * maintMakefile (build.sh.in): Remove an extraneous ")".
2779 * job.c (child_execute_job): Close saved FDs.
2780 * job.c (exec_command) [OS/2]: exec_command(): If the command
2781 can't be exec'ed and if the shell is not Unix-sh, then try again
2782 with argv = { "cmd", "/c", ... }. Normally, this code is never
2783 reached for the cmd shell unless the command really doesn't exist.
2784 (construct_command_argv_internal) [OS/2]: The code for cmd
2785 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2786 The CMD builtin commands are case insensitive so use strcasecmp().
2788 2004-03-19 Paul D. Smith <psmith@gnu.org>
2790 * read.c (do_define): Re-order line counter increment so the count
2791 is accurate (we were losing one line per define). Reported by
2792 Dave Yost <Dave@Yost.com>.
2794 2004-03-06 Paul D. Smith <psmith@gnu.org>
2796 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2798 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2799 * misc.c (message,error,fatal): Ditto.
2800 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2801 * config.h.W32.template: Ditto.
2802 * config.h-vms.template: Ditto.
2803 * config.ami.template: Ditto.
2805 2004-03-04 Paul D. Smith <psmith@gnu.org>
2807 * README.template: Add a note about broken /bin/sh on SunOS
2808 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2810 * misc.c (message, error, fatal): Don't use "..." if we're using
2811 varargs. ansi2knr should handle this but it doesn't work: it
2812 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2813 done. On many systems (SunOS for example) va_dcl is a #define.
2814 So, force the use of the non-"..." version on pre-ANSI compilers.
2816 * maintMakefile (sign-dist): Create some rules to help automate
2817 the new GNU ftp upload method.
2819 2004-02-24 Paul D. Smith <psmith@gnu.org>
2821 * config.h.W32.template: Add HAVE_STDARG_H
2822 * config.h-vms.template: Ditto.
2823 * config.ami.template: Ditto.
2825 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2827 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2828 * build_w32.bat: Remove extra "+".
2830 2004-02-23 Paul D. Smith <psmith@gnu.org>
2832 * make.h: Create an UNUSED macro to mark unused parameters.
2833 * (many): Clean up warnings by applying UNUSED, fixing
2834 signed/unsigned incompatibilities, etc.
2836 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2838 * filedef.h: Name the command_state enumeration.
2839 * file.c (set_command_state): Use the enumeration in the function
2842 * configure.in: Explicitly set SET_MAKE to empty, to disable
2843 MAKE=make even when no make already exists. Fix bug #3823.
2845 2004-02-22 Paul D. Smith <psmith@gnu.org>
2847 * maintMakefile: Perl script to clean up all non-CVS files. Use
2848 it on all the subdirectories for the cvs-clean target.
2850 * main.c (decode_switches): Require non-empty strings for all our
2851 string command-line options. Fixes Debian bug # 164165.
2853 * configure.in: Check for stdarg.h and varargs.h.
2854 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2855 for printing messages.
2856 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2861 A number of patches for OS/2 support from Andreas Buening
2862 <andreas.buening@nexgo.de>:
2864 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2865 disable the SIGCHLD handler.
2866 (reap_children) [OS/2]: Remove special handling of job_rfd.
2867 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2868 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2869 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2870 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2871 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2874 2004-02-21 Paul D. Smith <psmith@gnu.org>
2876 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2877 <mail@kristov.de> reports that if process_begin() fails we don't
2878 handle the error condition correctly in all cases.
2879 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2880 to have a newline on the message.
2882 * job.c (construct_command_argv_internal): Add "test" to UNIX
2883 sh_cmds[]. Fixes Savannah bug # 7606.
2885 2004-02-04 Paul D. Smith <psmith@gnu.org>
2887 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2888 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2889 Hartmut Becker <Hartmut.Becker@hp.com>.
2891 2004-01-21 Paul D. Smith <psmith@gnu.org>
2893 * job.c (load_too_high): Implement an algorithm to control the
2894 "thundering herd" problem when using -l to control job creation
2895 via the load average. The system only recomputes the load once a
2896 second but we can start many jobs in a second. To solve this we
2897 keep track of the number of jobs started in the last second and
2898 apply a weight to try to guess what a correct load would be.
2899 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2900 Also fixes bug #4693.
2901 (reap_children): Decrease the job count for this second.
2902 (start_job_command): Increase the job count for this second.
2904 * read.c (conditional_line): Expand the text after ifn?def before
2905 checking to see if it's a single word. Fixes bug #7257.
2907 2004-01-09 Paul D. Smith <psmith@gnu.org>
2909 * file.c (print_file): Recurse to print all targets in
2910 double-colon rules. Fixes bug #4518, reported (with patch) by
2911 Andrew Chatham <chatham@google.com>.
2913 2004-01-07 Paul D. Smith <psmith@gnu.org>
2915 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2916 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2917 AC_FUNC_SETVBUF_REVERSED.
2919 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2920 (MAKE Variable): Fix Savannah bug #4898.
2922 * job.c (construct_command_argv_internal): Add "!" to the list of
2923 shell escape chars. POSIX sh allows it to appear before a
2924 command, to negate the exit code. Fixes bug #6404.
2926 * implicit.c (pattern_search): When matching an implicit rule,
2927 remember which dependencies have the ignore_mtime flag set.
2928 Original fix provided in Savannah patch #2349, by Benoit
2929 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2931 2003-11-22 Paul D. Smith <psmith@gnu.org>
2933 * README.W32.template (Outputs): Clarification on -j with
2934 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2937 2003-11-02 Paul D. Smith <psmith@gnu.org>
2939 * function.c (func_if): Strip all the trailing whitespace from the
2940 condition, then don't expand it. Fixed bug # 5798.
2942 * expand.c (recursively_expand_for_file): If we're expanding a
2943 variable with no file context, then use the variable's context.
2946 2003-10-21 Paul D. Smith <psmith@gnu.org>
2948 * main.c (log_working_directory): Add newlines to printf()s.
2950 * README.cvs: Add a note to ignore warnings during autoreconf.
2952 * maintMakefile (po_repo): Set a new URL for PO file updates.
2953 (get-config/config.guess get-config/config.sub): Get these files
2954 from the Savannah config project instead of ftp.gnu.org.
2956 2003-10-05 Paul Eggert <eggert@twinsun.com>
2958 * main.c (main): Avoid potential subscript error if environ has
2961 2003-08-22 Paul D. Smith <psmith@gnu.org>
2963 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2964 systems which don't yet implement the C89 standard :-/.
2966 2003-07-18 Paul D. Smith <psmith@gnu.org>
2968 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2969 [WINDOWS32]: Initialize hash.
2971 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2973 * dir.c (read_dirstream): Provide a workaround for broken versions of
2974 the MinGW dirent structure.
2976 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2978 * w32/include/dirent.h: Add __MINGW32__ filter.
2980 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2982 * make.h: Add global declaration of *make_host.
2983 * main.c (print_usage): Remove local declaration of *make_host.
2984 (print_version): Display "This program built for ..." after Copyright
2987 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2989 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2990 execution of "makeinfo --html make.texi".
2992 2003-04-30 Paul D. Smith <psmith@gnu.org>
2994 * build.template: Make some changes to maybe allow this script to
2995 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2997 * README.OS2.template: New file for OS/2 support. Original
2998 contributed by Andreas Buening.
2999 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3002 2003-04-19 Paul D. Smith <psmith@gnu.org>
3004 Fix bug #1405: allow a target to match multiple pattern-specific
3007 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3008 variable.c, where they've always belonged.
3009 * rule.h: Move the prototypes and struct pattern_var as well.
3010 * variable.c (initialize_file_variables): Invoke
3011 lookup_pattern_var() in a loop, until no more matches are found.
3012 If a match is found, create a new variable set for the target's
3013 pattern variables. Then merge the contents of each matching
3014 pattern variable set into the target's pattern variable set.
3015 (lookup_pattern_var): Change this function to be usable
3016 in a loop. It takes a starting position: if NULL, start at the
3017 beginning; if non-NULL, start with the pattern variable after that
3018 position, and return the next matching pattern.
3019 (create_pattern_var): Create a unique instance of
3020 pattern-specific variables for every definition in the makefile.
3021 Don't combine the same pattern together. This allows us to
3022 process the variable handling properly even when the same pattern
3023 is used multiple times.
3024 (parse_variable_definition): New function: break out the parsing
3025 of a variable definition line from try_variable_definition.
3026 (try_variable_definition): Call parse_variable_definition to
3028 (print_variable_data_base): Print out pattern-specific variables.
3029 * variable.h (struct variable): Remember when a variable is
3030 conditional. Also remember its flavor.
3031 (struct pattern_var): Instead of keeping a variable set, we just
3032 keep a single variable for each pattern.
3033 * read.c (record_target_var): Each pattern variable contains only a
3034 single variable, not a set, so create it properly.
3035 * doc/make.texi (Pattern-specific): Document the new behavior.
3037 2003-04-17 Paul D. Smith <psmith@gnu.org>
3039 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3040 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3041 file/directory naming rules for VMS so I can't tell whether this
3044 2003-04-09 Paul D. Smith <psmith@gnu.org>
3046 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3047 DOS-style pathnames: backslash separators and drive specifiers.
3049 2003-03-28 Paul D. Smith <psmith@gnu.org>
3051 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3052 the intermediate flag on all targets. Fixes bug #2515.
3054 2003-03-24 Paul D. Smith <psmith@gnu.org>
3056 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3057 Upgrade to autoconf 2.57 and automake 1.7.3.
3059 * job.c: More OS/2 changes from Andreas Buening.
3061 * file.c (print_file): Fix variable initialization.
3064 * remake.c (notice_finished_file):
3066 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3067 some calls (like readdir()) return NULL in valid situations
3068 without resetting errno. Fixes bug #2846.
3070 2003-02-25 Paul D. Smith <psmith@gnu.org>
3072 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3074 * job.c (_is_unixy_shell) [OS/2]: New function.
3075 Set default shell to /bin/sh.
3076 (reap_children): Close the job_rfd pipe here since we don't use a
3078 (set_child_handler_action_flags): define this to empty on OS/2.
3079 (start_job_command): Close the jobserver pipe and use
3080 child_execute_job() instead of fork/exec.
3081 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3082 rather than exec'ing, then reconfigure stdin/stdout.
3083 (exec_command): Rewrite to use spawn instead of exec. Return the
3086 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3087 in DOS. Handle the TEMP environment variable as in DOS. Don't
3088 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3089 use -j in DOS mode. Use child_execute_job() instead of
3092 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3095 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3096 prototypes that return values.
3098 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3100 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3101 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3103 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3106 2003-02-24 Paul D. Smith <psmith@gnu.org>
3108 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3109 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3110 (child_execute_job) [VMS]: Handle error status properly.
3111 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3113 * function.c (func_shell): Use EINTRLOOP() while reading from the
3114 subshell pipe (Fixes bug #2502).
3115 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3117 * main.c (main): Ditto.
3119 2003-01-30 Paul D. Smith <psmith@gnu.org>
3121 * read.c (eval): eval() was not fully reentrant, because the
3122 collapsed buffer was static. Change it to be an automatic
3123 variable so that eval() can be invoked recursively.
3125 (eval): Apply patch # 1022: fix memory reference error on long
3126 target-specific variable lines.
3127 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3129 * function.c (check_numeric): Combine the is_numeric() function
3130 into this function, since it's only called from one place.
3131 Constify this function. Have it print the incorrect string in the
3132 error message. Fixes bug #2407.
3133 (strip_whitespace): Constify.
3134 (func_if): Constify.
3135 * expand.c (expand_argument): Constify.
3137 2003-01-29 Paul D. Smith <psmith@gnu.org>
3139 Fix bug # 2169, also reported by other people on various systems.
3141 * make.h: Some systems, such as Solaris and PTX, do not fully
3142 implement POSIX-compliant SA_RESTART functionality; important
3143 system calls like stat() and readdir() can still fail with EINTR
3144 even if SA_RESTART has been set on the signal handler. So,
3145 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3146 EINTR for system calls which return -1 or 0 (NULL), respectively,
3148 Also, remove the old atomic_stat()/atomic_readdir() and
3149 HAVE_BROKEN_RESTART handling.
3151 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3153 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3154 * remake.c (touch_file): Ditto.
3156 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3157 * read.c (construct_include_path): Ditto.
3158 * remake.c (name_mtime): Ditto.
3159 * vpath.c (selective_vpath_search): Ditto.
3160 * dir.c (find_directory): Ditto.
3161 (local_stat): Ditto.
3162 (find_directory): Use ENULLLOOP() to wrap opendir().
3163 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3165 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3166 atomic_readdir() handling.
3168 2003-01-22 Paul D. Smith <psmith@gnu.org>
3170 * function.c (func_call): Fix Bug #1744. If we're inside a
3171 recursive invocation of $(call ...), mask any of the outer
3172 invocation's arguments that aren't used by this one, so that this
3173 invocation doesn't "inherit" them accidentally.
3175 2002-12-05 Paul D. Smith <psmith@gnu.org>
3177 * function.c (subst_expand): Valery Khamenia reported a
3178 pathological performance hit when doing substitutions on very
3179 large values with lots of words: turns out we were invoking
3180 strlen() a ridiculous number of times. Instead of having each
3181 call to sindex() call strlen() again, keep track of how much of
3182 the text we've seen and pass the length to sindex().
3184 2002-11-19 Paul D. Smith <psmith@gnu.org>
3186 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3189 2002-11-16 Paul D. Smith <psmith@gnu.org>
3191 * NMakefile.template (OBJS): Add hash.c object file.
3192 * SMakefile.template (srcs): Ditto.
3193 * Makefile.ami (objs): Ditto.
3194 * build_w32.bat: Ditto.
3196 * Makefile.DOS.template: Remove extra dependencies.
3198 2002-10-25 Paul D. Smith <psmith@gnu.org>
3200 * expand.c (install_variable_buffer): New function. Install a new
3201 variable_buffer context and return the previous one.
3202 (restore_variable_buffer): New function. Free the current
3203 variable_buffer context and put a previously saved one back.
3204 * variable.h: Prototypes for {install,restore}_variable_buffer.
3205 * function.c (func_eval): Push a new variable_buffer context
3206 before we eval, then restore the old one when we're done.
3209 * read.c (install_conditionals): New function. Install a new
3210 conditional context and return the previous one.
3211 (restore_conditionals): New function. Free the current
3212 conditional context and put a previously saved one back.
3213 (eval): Use the {install,restore}_conditionals for "include"
3215 (eval_buffer): Use {install,restore}_conditionals to preserve the
3216 present conditional state before we evaluate the buffer.
3219 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3221 (Recursion): Add a variable index entry for CURDIR.
3223 * README.cvs: Update to appropriate versions.
3224 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3225 don't need to copy loadavg.c: automake is smart enough to create
3226 it for me. Still have a bug in automake related to ansi2knr tho.
3228 2002-10-14 Paul D. Smith <psmith@gnu.org>
3230 * remake.c (notice_finished_file): Only touch targets if they have
3231 at least one command (as per POSIX). Resolve Bug #1418.
3233 * *.c: Convert to using ANSI C-style function definitions.
3234 * Makefile.am: Enable the ansi2knr feature of automake.
3235 * configure.in: ditto.
3237 2002-10-13 Paul D. Smith <psmith@gnu.org>
3239 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3240 for automatic variable values like $^, etc. In the case of very
3241 large lists of prerequisites this causes problems. Instead reuse
3242 a static buffer (resizeable) for each variable.
3244 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3245 target-specific variable definitions. Check for it and set an
3247 (record_target_var): Set the export field to v_export if the
3248 "exported" flag is set.
3249 * doc/make.texi (Target-specific): Document the ability to use
3252 * doc/make.texi: Change the name of the section on automatic
3253 variables from "Automatic" to "Automatic Variables". Added text
3254 clarifying the scope of automatic variables.
3256 2002-10-04 Paul D. Smith <psmith@gnu.org>
3258 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3260 (record_files): Ditto.
3262 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3263 the search for the '=' to only within the enclosing parens.
3265 2002-10-03 Paul D. Smith <psmith@gnu.org>
3267 Version 3.80 released.
3269 * dir.c: Change hash functions to use K&R function definition style.
3270 * function.c: Ditto.
3272 * variable.c: Ditto.
3274 Update to automake 1.7.
3276 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3277 (pdf): Remove this target as automake now provides one.
3279 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3281 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3283 * makefile.com: Updates for GNU make 3.80.
3284 * makefile.vms: Ditto.
3286 2002-09-23 Paul D. Smith <psmith@gnu.org>
3288 * read.c (enum make_word_type): Remove w_comment.
3289 (get_next_mword): Don't treat comment characters as special; where
3290 this function is used we will never see a comment (it's stripped
3291 before we get here) and treating comments specially means that
3292 targets like "foo\#bar" aren't handled properly.
3294 2002-09-18 Paul D. Smith <psmith@gnu.org>
3296 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3298 * read.c (eval): Expansion of arguments to export/unexport was
3299 ignoring all arguments after the first one. Change the algorithm
3300 to expand the whole line once, then parse the results.
3302 2002-09-17 Paul D. Smith <psmith@gnu.org>
3304 Fix Bug #940 (plus another bug I found while looking at this):
3306 * read.c (record_target_var): enter_file() will add a new entry if
3307 it's a double-colon target: we don't want to do that in this
3308 situation. Invoke lookup_file() and only enter_file() if it does
3309 not already exist. If the file we get back is a double-colon then
3310 add this variable to the "root" double-colon target.
3312 * variable.c (initialize_file_variables): If this file is a
3313 double-colon target but is not the "root" target, then initialize
3314 the root and make the root's variable list the parent of our
3317 2002-09-13 Paul D. Smith <psmith@gnu.org>
3319 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3321 * hash.c (round_up_2): Get rid of a warning.
3323 2002-09-12 Paul D. Smith <psmith@gnu.org>
3325 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3326 so it doesn't complain about getloadavg.c.
3328 * commands.c (set_file_variables): Make sure we always alloca() at
3329 least 1 character for the value of $? (for '\0').
3331 2002-09-11 Paul D. Smith <psmith@gnu.org>
3333 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3334 macro to use RESULT instead of the incorrect _RESULT_.
3336 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3337 and atomic_readdir(). We need to #include dirent.h to get this to
3339 * misc.c (atomic_readdir): Fix typos.
3341 2002-09-10 Paul D. Smith <psmith@gnu.org>
3343 * read.c (eval): Expand variable lists given to export and
3344 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3345 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3347 * doc/make.texi (Variables/Recursion): Document this.
3348 (Conditional Syntax): And here.
3350 2002-09-09 Paul D. Smith <psmith@gnu.org>
3352 * configure.in: Check for memmove().
3354 2002-09-07 Paul D. Smith <psmith@gnu.org>
3356 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3357 Michael Sterrett <msterret@coat.com> reports that while it has
3358 SA_RESTART, it does not work properly.
3360 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3361 that invokes stat() and loops to do it again if it returns EINTR.
3362 (atomic_readdir): Ditto, with readdir().
3364 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3365 and readdir() to atomic_stat() and atomic_readdir().
3367 2002-09-04 Paul D. Smith <psmith@gnu.org>
3369 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3370 reports that GNU make sometimes doesn't recognize that targets can
3371 be made, when directories can be created as prerequisites. He
3372 reports that changing the order of predicates in the DEP->changed
3373 flag test so that lookup_file() is always performed, solves this
3376 2002-08-08 Paul D. Smith <psmith@gnu.org>
3378 * configure.in: Require a newer version of gettext.
3380 * misc.c (perror_with_name): Translate the format string (for
3381 right-to-left language support).
3382 (pfatal_with_name): Ditto.
3384 * main.c: Create a static array of strings to store the usage
3385 text. This is done to facilitate translations.
3386 (struct command_switch): Remove argdesc and description fields.
3387 (switches): Remove values for obsolete fields.
3388 (print_usage): Print each element of the usage array.
3390 * hash.c: Change function definitions to be K&R style.
3392 2002-08-02 Paul D. Smith <psmith@gnu.org>
3394 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3395 this one because it's too hard to get right. We'll look at it for
3397 * main.c (main): Don't create the .TARGETS variable.
3398 * variable.c (handle_special_var): Don't handle .TARGETS.
3400 2002-08-01 Paul D. Smith <psmith@gnu.org>
3402 * main.c (switches): Add a new option, -B (--always-make). If
3403 specified, make will rebuild all targets that it encounters even
3404 if they don't appear to be out of date.
3405 (always_make_flag): New flag.
3406 * make.h: Extern always_make_flag.
3407 * remake.c (update_file_1): Check always_make_flag; if it's set we
3408 will always rebuild any target we can, even if none of its
3409 prerequisites are newer.
3412 * doc/make.texi (Shell Function): Make it clear that make
3413 variables marked as "export" are not passed to instances of the
3416 Add new introspection variable .VARIABLES and .TARGETS.
3418 * variable.c (handle_special_var): New function. If the variable
3419 reference passed in is "special" (.VARIABLES or .TARGETS),
3420 calculate the new value if necessary. .VARIABLES is handled here:
3421 walk through the hash of defined variables and construct a value
3422 which is a list of the names. .TARGETS is handled by
3423 build_target_list().
3424 (lookup_variable): Invoke handle_special_var().
3425 * file.c (build_target_list): Walk through the hask of known files
3426 and construct a list of the names of all the ones marked as
3428 * main.c (main): Initialize them to empty (and as simple variables).
3429 * doc/make.texi (Special Variables): Document them.
3430 * NEWS: Mention them.
3432 * variable.h (struct variable): Add a new flag "exportable" which
3433 is true if the variable name is valid for export.
3434 * variable.c (define_variable_in_set): Set "exportable" when a new
3435 variable is defined.
3436 (target_environment): Use the "exportable" flag instead of
3437 re-checking the name here... an efficiency improvement.
3439 2002-07-31 Paul D. Smith <psmith@gnu.org>
3441 * config.h-vms.template: Updates to build on VMS. Thanks to
3442 Brian_Benning@aksteel.com for helping verify the build.
3443 * makefile.com: Build the new hash.c file.
3444 * hash.h: Use strcpmi(), not stricmp(), in the
3445 HAVE_CASE_INSENSITIVE_FS case.
3447 2002-07-30 Paul D. Smith <psmith@gnu.org>
3449 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3450 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3451 Reported by <Brian_Benning@aksteel.com>.
3453 2002-07-10 Paul D. Smith <psmith@gnu.org>
3455 * variable.c (pop_variable_scope): Remove variable made unused by
3456 new hash infrastructure.
3457 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3458 comparisons as well as name comparisons.
3459 * variable.h: Add a prototype for new hash_init_function_table().
3460 * file.c (lookup_file): Remove variables made unused by new hash
3462 * dir.c (directory_contents_hash_2): Missing return of hash value.
3463 (dir_contents_file_exists_p): Remove variables made unused by new
3464 hash infrastructure.
3467 Installed Greg McGary's integration of the hash functions from the
3468 GNU id-utils package:
3470 2002-07-10 Greg McGary <greg@mcgary.org>
3472 * scripts/functions/filter-out: Add literals to to the
3473 pattern space in order to add complexity, and trigger
3474 use of an internal hash table. Fix documentation strings.
3475 * scripts/targets/INTERMEDIATE: Reverse order of files
3476 passed to expected `rm' command.
3478 2002-07-10 Greg McGary <greg@mcgary.org>

3570 2002-07-10 Paul D. Smith <psmith@gnu.org>
3572 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3573 prerequisite list. A real SysV make will expand the entire
3574 prerequisites list _twice_: we don't do that as it's a big
3575 backward-compatibility problem. We only replace those specific
3578 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3579 references left in the list of prerequisites. Check for .POSIX as
3580 we record targets, so we can disable non-POSIX behavior while
3581 reading makefiles as well as running them.
3582 (eval): Check the prerequisite list to see if we have anything
3583 that looks like a SysV prerequisite variable reference.
3585 2002-07-09 Paul D. Smith <psmith@gnu.org>
3587 * doc/make.texi (Prerequisite Types): Add a new section describing
3588 order-only prerequisites.
3590 * read.c (uniquize_deps): If we have the same file as both a
3591 normal and order-only prereq, get rid of the order-only prereq,
3592 since the normal one supersedes it.
3594 2002-07-08 Paul D. Smith <psmith@gnu.org>
3596 * AUTHORS: Added Greg McGary to the AUTHORS file.
3597 * NEWS: Blurbed order-only prerequisites.
3598 * file.c (print_file): Show order-only deps properly when printing
3601 * maintMakefile: Add "update" targets for wget'ing the latest
3602 versions of various external files. Taken from Makefile.maint in
3605 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3606 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3608 2002-07-07 Paul D. Smith <psmith@gnu.org>
3610 * po/*.po: Remove. We'll use wget to retrieve them at release
3613 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3614 rather than a shell you get an exception. Make sure we look up
3615 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3617 * remake.c (notice_finished_file): Fix handling of -t flag.
3618 Patch provided by Henning Makholm <henning@makholm.net>.
3620 * implicit.c (pattern_search): Some systems apparently run short
3621 of stack space, and using alloca() in this function caused an
3622 overrun. I modified it to use xmalloc() on the two variables
3623 which seemed like they might get large. Fixes Bug #476.
3625 * main.c (print_version): Update copyright notice to conform with
3627 (print_usage): Update help output.
3629 * function.c (func_eval): Create a new make function, $(eval
3630 ...). Expand the arguments, put them into a buffer, then invoke
3631 eval_buffer() on the resulting string.
3632 (func_quote): Create a new function, $(quote VARNAME). Inserts
3633 the value of the variable VARNAME without expanding it any
3636 * read.c (struct ebuffer): Change the linebuffer structure to an
3637 "eval buffer", which can be either a file or a buffer.
3638 (eval_makefile): Move the code in the old read_makefile() which
3639 located a makefile into here: create a struct ebuffer with that
3640 information. Have it invoke the new function eval() with that
3642 (eval_buffer): Create a new function that creates a struct ebuffer
3643 that holds a string buffer instead of a file. Have it invoke
3644 eval() with that ebuffer.
3645 (eval): New function that contains the guts of the old
3646 read_makefile() function: this function parses makefiles. Obtains
3647 data to parse from the provided ebuffer. Some modifications to
3648 make the flow of the function cleaner and clearer. Still could
3649 use some work here...
3650 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3651 contents of the define/endef variable from the ebuffer.
3652 (readstring): Read the next line from a string-style ebuffer.
3653 (readline): Read the next line from an ebuffer. If it's a string
3654 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3657 * dep.h (eval_buffer): Prototype eval_buffer();
3659 * variable.c (do_variable_definition): Make sure that all
3660 non-target-specific variables are registered in the global set.
3661 If we're invoked from an $(eval ...) we might be inside a $(call
3662 ...) or other function which has pushed a variable scope; we still
3663 want to define our variables from evaluated makefile code in the
3666 2002-07-03 Greg McGary <greg@mcgary.org>
3668 * dep.h (struct dep) [ignore_mtime]: New member.
3669 [changed]: convert to a bitfield.
3670 * implicit.c (pattern_search): Zero ignore_mtime.
3671 * main.c (main, handle_non_switch_argument): Likewise.
3672 * rule.c (convert_suffix_rule): Likewise.
3673 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3674 (read_makefile): Parse '|' in prerequisite list.
3675 (uniquize_deps): Consider ignore_mtime when comparing deps.
3676 * remake.c (update_file_1, check_dep): Don't force remake for
3677 dependencies that have d->ignore_mtime.
3678 * commands.c (FILE_LIST_SEPARATOR): New constant.
3679 (set_file_variables): Don't include a
3680 prerequisite in $+, $^ or $? if d->ignore_mtime.
3683 2002-06-18 Paul D. Smith <psmith@gnu.org>
3685 * make.texinfo: Updates for next revision. New date/rev/etc.
3686 Recreate all Info menus. Change license on the manual to the GNU
3687 Free Documentation License. A number of typos.
3688 (Variables Simplify): Don't use "-" before it's defined.
3689 (Automatic Prerequisites): Rewrite the target example to work
3690 properly if the compile fails. Remove incorrect comments about
3691 how "set -e" behaves.
3692 (Text Functions): Move the "word", "wordlist", "words", and
3693 "firstword" functions here, from "File Name Functions".
3694 * make-stds.texi: Update from latest GNU version.
3695 * fdl.texi: (created) Import the latest GNU version.
3697 2002-06-06 Paul D. Smith <psmith@gnu.org>
3699 * variable.c (do_variable_definition): New function: extract the
3700 part of try_variable_definition() that actually sets the value
3701 into a separate function.
3702 (try_variable_definition): Call do_variable_definition() after
3703 parsing the variable definition string.
3704 (define_variable_in_set): Make the name argument const.
3706 * variable.h (enum variable_flavor): Make public.
3707 (do_variable_definition): Create prototype.
3709 * read.c (read_all_makefiles): Create a new built-in variable,
3711 (read_makefile): Add each makefile read in to this variable value.
3713 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3715 * Makefile.DOS.template: Tweak according to changes in the
3716 distribution. Add back the dependencies of *.o files.
3718 * configh.dos.template: Synchronize with config.h.in.
3720 2002-05-09 Paul D. Smith <psmith@gnu.org>
3722 * file.c (file_timestamp_now): Use K&R function declaration.
3724 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3725 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3726 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3727 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3728 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3729 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3730 nlist.n_name is a pointer rather than an array.
3732 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3733 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3734 * configure.in: Use it instead of the old version.
3736 * main.c (main): Prefer setvbuf() to setlinebuf().
3738 2002-05-08 Paul D. Smith <psmith@gnu.org>
3740 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3741 (loadavg_LDADD): Ditto.
3743 2002-04-29 Paul D. Smith <psmith@gnu.org>
3745 * expand.c (recursively_expand_for_file): Rename
3746 recursively_expand() to recursively_expand_for_file() and provide
3747 an extra argument, struct file. If the argument is provided, set
3748 the variable scope to that of the file before expanding.
3749 * variable.h (recursively_expand): Make this a macro that invokes
3750 recursively_expand_for_file() with a NULL file pointer.
3751 * variable.c (target_environment): Call the renamed function and
3752 provide the current file context.
3753 Fixes Debian bug #144306.
3755 2002-04-28 Paul D. Smith <psmith@gnu.org>
3757 Allow $(call ...) user-defined variables to be self-referencing
3758 without throwing an error. Allows implementation of transitive
3759 closures, among other possibly useful things.
3760 Requested by: Philip Guenther <guenther@sendmail.com>
3762 * variable.h (struct variable): Add a new field: exp_count, and
3763 new macros to hold its size and maximum value.
3764 (warn_undefined): Make this a macro.
3765 * variable.c (define_variable_in_set): Initialize it.
3766 * expand.c (recursively_expand): If we detect recursive expansion
3767 of a variable, check the exp_count field. If it's greater than 0
3768 allow the recursion and decrement the count.
3769 (warn_undefined): Remove this (now a macro in variable.h).
3770 * function.c (func_call): Before we expand the user-defined
3771 function, modify its exp_count field to contain the maximum
3772 number of recursive calls we'll allow. After the call, reset it
3775 2002-04-21 Paul D. Smith <psmith@gnu.org>
3777 Modified to use latest autoconf (2.53), automake (1.6.1), and
3778 gettext (0.11.1). We're using gettext's new "external" support,
3779 to avoid including libintl source with GNU make.
3781 * README.cvs: New file. Explain how to build GNU make from CVS.
3783 * configure.in: Modify checking for the system glob library.
3784 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3785 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3786 etc. will manage it correctly). Set an automake conditional
3787 USE_LOCAL_GLOB to decide whether to compile the glob library.
3789 * getloadavg.c (main): Include make.h in the "TEST" program to
3792 * Makefile.am: Remove special rules for loadavg. Replace them
3793 with Automake capabilities for building extra programs.
3795 * signame.c: This file does nothing if the system provide
3796 strsignal(). If not, it implements strsignal(). If the system
3797 doesn't define sys_siglist, then we make our own; otherwise we use
3799 * signame.h: Removed.
3801 * main.c (main): No need to invoke signame_init(). Update copyright.
3803 * ABOUT-NLS: Removed.
3804 * gettext.c: Removed.
3805 * gettext.h: Get a simplified copy from the gettext package.
3807 * i18n/*.po: Moved to po/.
3810 * config/*: Created. Contains package configuration helper files.
3811 * config.guess, config.sub: Moved to config directory.
3813 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3814 Rework to use new-style autoconf features. Use the "external"
3815 mode for gettext. Make the build.sh config file conditional on
3816 whether build.sh.in exists, to avoid autoconf errors.
3817 * acinclude.m4: Removed almost all macros as being obsolete.
3818 Rewrote remaining macros to use AC_DEFINE.
3819 * acconfig.h: Removed.
3821 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3822 conditional to handle customs support. Remove special handling
3825 2002-04-20 Paul D. Smith <psmith@gnu.org>
3827 * function.c (func_call): Don't mark the argument variables $1,
3828 etc. as recursive. They've already been fully expanded so
3829 there's no need to do it again, and doing so strips escaped $'s.
3830 Reported by Sebastian Glita <glseba@yahoo.com>.
3832 * remake.c (notice_finished_file): Walk through double-colon
3833 entries via the prev field, not the next field!
3834 Reported by Greg McGary <greg@mcgary.org>.
3836 * main.c (main): If the user specifies -q and asks for a specific
3837 target which is a makefile, we got an assert. In that case it
3838 turns out we should continue normally instead.
3840 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3842 * i18n/he.po: Installed a new translation.
3844 2002-01-07 Paul D. Smith <psmith@gnu.org>
3846 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3848 2001-12-04 Paul D. Smith <psmith@gnu.org>
3850 * i18n/ja.po: Installed an updated translation.
3852 2001-09-06 Paul Eggert <eggert@twinsun.com>
3854 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3855 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3857 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3859 (main): Get rid of any avoidable limit on stack size.
3861 2001-09-04 Paul D. Smith <psmith@gnu.org>
3863 * i18n/da.po: Installed an updated translation.
3865 2001-08-03 Paul D. Smith <psmith@gnu.org>
3867 * i18n/fr.po: Installed an updated translation.
3868 Resolves Debian bug #106720.
3870 2001-06-13 Paul D. Smith <psmith@gnu.org>
3872 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3875 2001-06-11 Paul D. Smith <psmith@gnu.org>
3877 * i18n/ko.po: Installed a new translation.
3879 2001-05-06 Paul D. Smith <psmith@gnu.org>
3881 Modify the EINTR handling.
3883 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3884 the way in which we manage the file descriptor/signal handler race
3885 trap to be more efficient.
3887 2001-05-06 Paul Eggert <eggert@twinsun.com>
3889 Restart almost all system calls that are interrupted, instead
3890 of worrying about EINTR. The lone exception is the read() for
3893 * configure.in (HAVE_SA_RESTART): New macro.
3894 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3895 * main.c (main): Use SA_RESTART instead of the old,
3896 nonstandard SA_INTERRUPT.
3898 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3899 * main.c (bsd_signal): New function or macro,
3900 if the implementation doesn't supply it.
3901 (The bsd_signal function will be in POSIX 1003.1-200x.)
3902 (HANDLESIG): Remove.
3903 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3905 * make.h (EINTR_SET): Remove.
3906 (SA_RESTART): New macro.
3908 * arscan.c (ar_member_touch): Don't worry about EINTR.
3909 * function.c (func_shell): Likewise.
3910 * job.c (reap_children, free_child, new_job): Likewise.
3911 * main.c (main): Likewise.
3912 * remake.c (touch_file, name_mtime): Likewise.
3914 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3915 if fstat failed with errno!=EINTR, the error was ignored.
3917 * job.c (set_child_handler_action_flags): New function.
3918 (new_job): Use it to temporarily clear the SIGCHLD action flags
3919 while reading the token.
3921 2001-05-02 Paul D. Smith <psmith@gnu.org>
3923 * job.c (start_job_command): Don't add define/endef per-line flags
3924 to the top-level flags setting.
3926 2001-04-03 Paul D. Smith <psmith@gnu.org>
3928 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3929 bit on error, so check for odd return values, not non-0 return
3931 (VMS_get_member_info): Calculate the timezone differences correctly.
3932 Reported by John Fowler <jfowler@nyx.net>.
3935 2001-03-14 Paul D. Smith <psmith@gnu.org>
3937 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3938 value before invoking define_variable().
3939 Reported by John Fowler <jfowler@nyx.net>.
3941 2001-02-07 Paul D. Smith <psmith@gnu.org>
3943 * read.c (record_target_var): If we reset the variable due to a
3944 command-line variable setting overriding it, turn off the "append"
3947 2001-01-17 Paul D. Smith <psmith@gnu.org>
3949 * variable.c (lookup_variable) [VMS]: When getting values from the
3950 environment, allocate enough space for the _value_ plus escapes,
3951 not enough space for the name plus escapes :-/.
3952 Reported by John Fowler <jfowler@nyx.net>.
3954 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3955 warnings that make generates, so it doesn't look like an error.
3956 Reported by Karl Berry <karl@gnu.org>.
3959 Fix for PR/2020: Rework appended target-specific variables. I'm
3960 fairly confident this algorithm is finally correct.
3962 * expand.c (allocated_variable_append): Rewrite. Instead of
3963 expanding each appended variable then adding all the expanded
3964 strings together, we append all the unexpanded values going up
3965 through the variable set contexts, then expand the final result.
3966 This behaves just like non-target-specific appended variable
3967 values, while the old way didn't in various corner cases.
3968 (variable_append): New function: recursively append the unexpanded
3969 value of a variable, walking from the outermost variable scope to
3971 * variable.c (lookup_variable): Remove the code that looked up the
3972 variable set list if the found variable was "append". We don't
3974 (lookup_variable_in_set): Make this non-static so we can use it
3976 (try_variable_definition): Use lookup_variable_in_set() rather
3977 than faking out current_variable_set_list by hand (cleanup).
3978 * variable.h: Add a prototype for the now non-static
3979 lookup_variable_in_set().
3981 2000-11-17 Paul D. Smith <psmith@gnu.org>
3983 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3984 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3985 before throwing a fit.
3987 2000-11-17 Paul D. Smith <psmith@gnu.org>
3989 * read.c (readline): CRLF calculations had a hole, if you hit the
3990 buffer grow scenario just right. Reworked the algorithm to avoid
3991 the need for len or lastlen at all. Problem description with
3992 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3994 2000-10-24 Paul D. Smith <psmith@gnu.org>
3996 * gettext.c (SWAP): Declare this with the prototype, otherwise
3997 some systems don't work (non-32-bit? Reported for Cray T3E).
3998 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4000 2000-10-05 Paul D. Smith <psmith@gnu.org>
4002 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4003 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4005 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4007 2000-09-22 Paul D. Smith <psmith@gnu.org>
4009 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4010 parts of the real gettext.h here, and we expect to really include
4011 the real gettext.h later. If we keep this #define, it's ignored.
4013 2000-09-21 Paul D. Smith <psmith@gnu.org>
4015 * main.c (log_working_directory): Rework the text to use complete
4016 sentences, to make life simpler for the translators.
4018 2000-08-29 Paul D. Smith <psmith@gnu.org>
4020 * file.c (remove_intermediates): Print a debug message before we
4021 remove intermediate files, so the user (if she uses -d) knows
4024 2000-08-21 Paul D. Smith <psmith@gnu.org>
4026 * variable.c (try_variable_definition): Change how we handle
4027 target-specific append variable defns: instead of just setting the
4028 value, expand it as an append _but_ only within the current
4029 target's context. Otherwise we lose all but the last value if the
4030 variable is appended more than once within the current target
4031 context. Fixes PR/1831.
4033 2000-08-16 Paul D. Smith <psmith@gnu.org>
4035 * function.c (func_shell): Nul-terminate the buffer before
4036 printing an exec error message (just in case it's not!).
4037 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4039 2000-07-25 Paul D. Smith <psmith@gnu.org>
4041 * job.c (construct_command_argv_internal): Add "~" to the list of
4042 sh_chars[] which disallow optimizing out the shell call.
4044 2000-07-23 Paul Eggert <eggert@twinsun.com>
4046 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4047 supersedes --disable-nsec-timestamps.
4048 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4049 * README: Remove --disable-nsec-timestamps.
4051 * filedef.h (struct file.low_resolution_time): New member.
4052 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4053 * remake.c (update_file_1):
4054 Avoid spurious rebuilds due to low resolution time stamps,
4055 generalizing the earlier code that applied only to archive members.
4056 (f_mtime): Archive members always have low resolution time stamps.
4058 * configure.in: Remove --disable-nsec-timestamps, as this has
4059 been superseded by .LOW_RESOLUTION_TIME.
4061 2000-07-23 Paul Eggert <eggert@twinsun.com>
4063 * configure.in (enable_nsec_timestamps): Renamed from
4064 make_cv_nsec_timestamps, since enable/disable options
4065 shouldn't be cached.
4067 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4068 and Paul Eggert <eggert@twinsun.com>
4070 * file.c (file_timestamp_now):
4071 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4072 so that clock_gettime is not linked unless needed.
4074 * filedef.h (FILE_TIMESTAMP_HI_RES):
4075 Remove definition; "configure" now does this.
4077 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4078 to before high resolution file timestamp check,
4079 since that check now uses uintmax_t.
4080 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4081 high resolution file timestamps.
4082 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4083 so that we don't link in clock_gettime unnecessarily.
4085 2000-07-17 Paul D. Smith <psmith@gnu.org>
4087 * i18n/ja.po: New version of the translation file.
4089 2000-07-07 Paul D. Smith <psmith@gnu.org>
4091 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4092 the offset calculation.
4093 (name_mtime): Replace EINTR test with EINTR_SET macro.
4095 2000-07-07 Paul Eggert <eggert@twinsun.com>
4099 * remake.c (update_file_1):
4100 Avoid spurious rebuilds of archive members due to their
4101 timestamp resolution being only one second.
4102 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4103 the clock's resolution being lower than file timestamps'.
4104 When warning about future timestamps, report only the discrepancy,
4105 not the absolute value of the timestamp and the current time.
4107 * file.c (file_timestamp_now): New arg RESOLUTION.
4108 * filedef.h (file_timestamp_now): Likewise.
4109 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4111 2000-07-05 Paul D. Smith <psmith@gnu.org>
4113 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4114 to listp. Fixes PR/1793.
4116 2000-06-26 Paul Eggert <eggert@twinsun.com>
4118 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4120 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4122 * remake.c (f_mtime): Remove unused var memtime.
4124 2000-06-25 Martin Buchholz <martin@xemacs.org>
4126 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4127 Ran spell-check on make.texinfo.
4129 2000-06-23 Paul D. Smith <psmith@gnu.org>
4131 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4132 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4133 * make.h: Define these macros.
4135 * Version 3.79.1 released.
4137 * configure.in: Add a new option, --disable-nsec-timestamps, to
4138 avoid using sub-second timestamps on systems that support it. It
4139 can lead to problems, e.g. if your makefile relies on "cp -p".
4140 * README.template: Document the issue with "cp -p".
4142 * config.guess, config.sub: Updated.
