485 SYS_SIGLIST_DECLARED.
486 Include <sys/version.h> because ports of GCC 4.3.0 and later no

488 defined automatically.
490 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
491 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
492 instead of using the hardcoded ones.
493 (SUBDIRS): doc subdir added.
494 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
495 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
496 create html formated docs. texi2html may not be ported to DOS.
497 (make.info, make.dvi, make.ps, make.html): Make targets depend on

540 * implicit.c (pattern_search): Add back support for order-only
541 prerequisites for secondary expansion implicit rules, that were
542 accidentally dropped. If we find a "|", enable order-only mode
543 and set IGNORE_MTIME on all deps that are seen afterward.
544 (pattern_search): Fix memory leaks: for intermediate files where
545 we've already set the file variable and pattern variable sets, be
546 sure to either save or free them as appropriate.
548 2009-09-23 Paul Smith <psmith@gnu.org>
550 Rework the way secondary expansion is stored, for efficiency.
551 This changes secondary expansion so that ONLY WHEN we know we have
552 a possibility of needing secondary expansion, do we defer the
553 secondary expansion. This means more parsing the deps but we use
554 a lot less memory (due to the strcache). Also, this fixes
557 * read.c (eval): Don't parse the dep string here anymore.
558 (record_files): Take the dep argument as an unparsed string. If
559 secondary expansion is enabled AND the prereq string has a '$' in
560 it, then set NEED_2ND_EXPANSION and keep the entire string.
561 Otherwise, parse the dep string here to construct the dep list
562 with the names in the strcache.
564 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
565 duplicate the name string (others are in the strcache).
567 * implicit.c: Remove struct idep and free_idep_chain(): unused.
568 (struct patdeps): New structure to store prereq information.
569 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
570 which prerequisites need expansion, and expand only those.
572 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
573 and enter_prereqs(). split_prereqs() takes a fully-expanded string
574 and splits it into a DEP list, handling order-only prereqs.
575 (enter_prereqs): This function enters a list of DEPs into the file
576 database. If there's a stem defined, expand any pattern chars.
577 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
578 set. Use the above functions.
579 (snap_deps): Only perform second expansion on prereqs that need it,
580 as defined by the NEED_2ND_EXPANSION flag.
581 (print_prereqs): New function to print the prereqs
582 (print_file): Call print_prereqs() rather than print inline.
584 * hash.h (STRING_COMPARE): Take advantage of strcache() by
586 (STRING_N_COMPARE): Ditto.
587 (ISTRING_COMPARE): Ditto.
589 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
590 (parse_file_seq): Return void*
591 * read.c (parse_file_seq): Return void*.
592 (eval): Invoke macroized version of parse_file_seq()
593 * default.c (set_default_suffixes): Ditto.
594 * file.c (split_prereqs): Ditto.
595 * function.c (string_glob): Ditto.
596 * main.c (main): Ditto.
597 * rule.c (install_pattern_rule): Ditto.
599 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
601 2009-09-16 Paul Smith <psmith@gnu.org>
603 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
605 * dep.h: Create alloc_dep() / free_dep() macros.
607 * implicit.c (pattern_search): Take advantage of the new
608 parse_file_seq() to add the directory prefix to each prereq.
610 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
611 all. Avoid reversing chains. Support adding prefixes.
612 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
613 cached/non-cached results.
614 (eval): Remove multi_glob() & invoke new parse_file_seq().
615 * rule.c (install_pattern_rule): Ditto.
616 * main.c (main): Ditto.
617 * implicit.c (pattern_search): Ditto.
618 * function.c (string_glob): Ditto.
619 * file.c (parse_prereqs): Ditto.
620 * default.c (set_default_suffixes): Ditto.
622 * variable.c (parse_variable_definition): Don't run off the end of
623 the string if it ends in whitespace (found with valgrind).
625 * commands.c (set_file_variables): Keep space for all targets in
626 $? if -B is given (found with valgrind).
628 2009-09-15 Paul Smith <psmith@gnu.org>
630 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
631 (xcalloc): Add new function.
632 * make.h: New declarations.
634 * ar.c (ar_glob_match): New calling method for concat().
635 * main.c (main): Ditto.
636 (decode_env_switches): Ditto.
637 * read.c (eval_makefile): Ditto.
638 (tilde_expand): Ditto.
639 (parse_file_seq): Ditto.
640 * variable.c (target_environment): Ditto.
641 (sync_Path_environment): Ditto.
643 * ar.c (ar_glob_match): Use xcalloc().
644 * dir.c (file_impossible): Ditto.
645 * file.c (enter_file): Ditto.
646 * job.c (new_job): Ditto.
647 * read.c (parse_file_seq): Ditto.
648 * vmsfunctions.c (opendir): Ditto.
650 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
652 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
653 inside the loop that looks up environment for PATH.
655 2009-08-31 Eli Zaretskii <eliz@gnu.org>
657 * function.c (windows32_openpipe): Update envp after calling
658 sync_Path_environment.
660 2009-08-02 Paul Smith <psmith@gnu.org>
662 * remake.c (notice_finished_file): Ensure file->cmds is not null
663 before looping through them. Fixes Savannah bug #21824.
665 * doc/make.texi (Wildcard Examples): Clarify when objects is
666 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
667 (Include): Clarify the behavior of -include.
668 Fixes Savannah bug #18963.
670 2009-08-01 Paul Smith <psmith@gnu.org>
672 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
673 etc. come on the command line. Fixes Savannah bug #27093.
675 * expand.c (expand_argument): If the argument is large enough use
676 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
678 * variable.c (do_variable_definition): Avoid using alloca() to
679 hold values, which can be large. Fixes Savannah bug #23960.
681 * job.c (new_job): Use memmove() instead of strcpy() since both
682 pointers are in the same memory block. Fixes Savannah bug #27148.
683 Patch by Petr Machata.
685 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
687 * job.c (construct_command_argv_internal): Add "ulimit" and
688 "unset" to the sh_cmds for Unixy shells.
690 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
692 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
693 that set make_cv_sys_gnu_glob, so they are also correctly set
694 when the cache has been populated before.
696 2009-07-04 Eli Zaretskii <eliz@gnu.org>
698 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
699 exist, as realpath(3) does where it's supported.
701 2006-07-04 Eli Zaretskii <eliz@gnu.org>
703 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
704 (abspath): Support systems that define HAVE_DOS_PATHS (have
705 drive letters in their file names). Use IS_PATHSEP instead of a
706 literal '/' comparison. Fixes Savannah bug #26886.
708 2009-06-14 Paul Smith <psmith@gnu.org>
710 * remake.c (update_file_1): Remember the original file we marked
711 as updating, so we can clear that flag again. If we find a target
712 via vpath, FILE might change.
713 (check_dep): Ditto. Fixes Savannah bug #13529.
714 Patch by Reid Madsen <reid.madsen@tek.com>.
716 2009-06-13 Paul Smith <psmith@gnu.org>
718 * doc/make.texi (MAKEFILES Variable): Be explicit that files
719 included by MAKEFILES cannot give default goals.
720 * read.c (eval): If set_default is not set, pass the no-default-goal
721 value when we read included makefiles. Fixes Savannah bug #13401.
723 * ar.c (ar_name): Ensure that targets with empty parens aren't
724 considered archive member references: archive members must have a
725 non-empty "member" string. Fixes Savannah bug #18435.
727 * function.c (string_glob): Rely on multi_glob() to determine
728 whether files exist or not. Remove call to file_exists_p() which
729 is not always correct. Fixes Savannah bug #21231.
730 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
731 then only files that really exist will be returned.
732 * dep.h: Add new argument to multi_glob().
733 * rule.c (install_pattern_rule): Ditto.
734 * read.c (eval): Ditto.
735 * main.c (main): Ditto.
736 * implicit.c (pattern_search): Ditto.
737 * file.c (parse_prereqs): Ditto.
738 * default.c (set_default_suffixes): Ditto.
740 2009-06-09 Paul Smith <psmith@gnu.org>
742 * commands.c (set_file_variables): If always_make_flag is set,
743 always add the prereq to $?. Fixes Savannah bug #17825.
745 * remake.c (update_file_1): When rebuilding deps of FILE, also try
746 to rebuild the deps of all the also_make targets for that file.
747 Fixes Savannah bug #19108.
749 * implicit.c (pattern_search): Undo test for is_target, added by
750 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
751 Rule Search Algorithm". Fixes Savannah bug #17752.
753 * main.c (clean_jobserver): Clear the jobserver_fds options and
754 set job_slots to the default when we clean up.
755 (define_makeflags): Return the new MAKEFLAGS value.
756 (main): Reset MAKEFLAGS in the environment when we re-exec.
757 Fixes Savannah bug #18124.
759 2009-06-08 Paul Smith <psmith@gnu.org>
761 * read.c (eval): Collapse continuations post-semicolon on target-
762 specific variables. Fixes Savannah bug #17521.
764 2009-06-07 Paul Smith <psmith@gnu.org>
766 * job.c (reap_children): For older systems without waitpid() (are
767 there any of these left?) run wait(2) inside EINTRLOOP to handle
768 EINTR errors. Fixes Savannah bug #16401.
770 * (various): Debug message cleanup. Fixes Savannah bug #16469.
772 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
774 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
775 not the end, to catch second expansion $(eval ...) defining new
776 target/prereq relationships during snap_deps.
777 Fixes Savannah bug #24622.
779 * read.c (record_files): The second-expansion "f->updating" hack
780 was not completely correct: if assumed that the target with
781 commands always had prerequisites; if one didn't then the ordering
782 was messed up. Fixed for now to use f->updating to decide whether
783 to preserve the last element in the deps list... but this whole
784 area of constructing and reversing the deps list is too confusing
785 and needs to be reworked. Fixes Savannah bug #21198.
787 2009-06-06 Paul Smith <psmith@gnu.org>
789 * hash.c (hash_insert): Remove useless test for NULL.
790 Fixes Savannah bug #21823.
792 * make.h: Move SET_STACK_SIZE determination to make.h.
793 * main.c (main): New global variable, STACK_LIMIT, holds the
794 original stack limit when make was started.
795 * job.c (start_job_command): Reset the stack limit, if we changed it.
796 Fixes Savannah bug #22010.
798 * remake.c (check_dep): Only set the target's state to not-started
799 if it's not already running. Found this while testing -j10 builds
800 of glibc: various targets were being rebuilt multiple times.
801 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
804 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
805 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
808 2009-06-04 Paul Smith <psmith@gnu.org>
810 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
812 * maintMakefile: Modify access of config and gnulib Savannah
813 modules to use GIT instead of CVS.
815 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
816 Fixes Savannah bug #24655.
818 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
819 this can happen during some invocations of $(eval ...) for example.
820 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
822 2009-06-02 Paul Smith <psmith@gnu.org>
824 * configure.in: Check for fileno()
825 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
826 for the makefile file so invocations of $(shell ...) don't inherit it.
827 Fixes Savannah bug #24277.
829 2009-06-01 Paul Smith <psmith@gnu.org>
831 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
832 expansion was handled incorrectly. Rework the default goal
833 handling to save the variable only. Remove default_goal_file and
835 * read.c (eval): Check default_goal_var, not default_goal_name.
836 * read.c (record_target_var): Don't check default_goal_file here.
838 2009-05-31 Paul Smith <psmith@gnu.org>
840 * main.c (main): Expand the .DEFAULT_GOAL variable before using
841 it, and if the multi_glob() returns nothing (say it expanded to
842 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
844 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
845 $(and ..) to the reference. Fixes Savannah bug #25694.
847 * make.1: Be clear that some recipes will be executed even with -n.
848 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
850 * doc/make.texi (Override Directive): Make more clear how
851 overrides and appends interact.
852 Elucidates part of Savannah bug #26207.
854 * read.c (record_target_var): Don't reset the origin on
855 target-specific variables; try_variable_definition() will handle
856 this correctly. Fixes Savannah bug #26207.
858 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
859 Fixes Savannah bug #25712.
861 * implicit.c (pattern_search): Keep a pointer to the beginning of
862 the filename and save that instead of the constructed pointer.
863 Fixes Savannah bug #26593.
864 Patch by Mark Seaborn <mrs@mythic-beasts.com>
866 2009-05-30 Paul Smith <psmith@gnu.org>
868 * doc/make.texi (Multi-Line): Add a description of the new abilities
869 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
870 "command sequence" vs. "recipe" syntax.
871 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
872 after a define, to create variables with those flavors.
874 2009-05-25 Paul Smith <psmith@gnu.org>
876 Reworked the parser for variable assignments to allow multiple
877 modifiers, and in any order. Also allows variable and
878 prerequisites to be modifier names ('export', 'private', etc.)
880 * NEWS: Add notes about user-visible changes.
882 * read.c (struct vmodifiers): Remember what modifiers were seen.
883 (parse_var_assignment): New function to parse variable assignments.
884 (eval): Call the new function. Handle variable assignments earlier.
886 * variable.c (parse_variable_definition): Only parse; don't create var.
887 (assign_variable_definition): Call parse, then create the var.
889 2009-05-24 Paul Smith <psmith@gnu.org>
891 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
892 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
894 2009-03-14 Eli Zaretskii <eliz@gnu.org>
896 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
897 Fixes Savannah bug #25412.
899 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
900 prototype for xmalloc.
901 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
902 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
903 Loop over an array of extensions, instead of duplicating the same
904 code inline. Use SearchPath followed by CreateFile, instead of
905 the obsolete OpenFile. Fixes Savannah bug #17277.
906 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
907 to `find_file'. Fixes Savannah bug #25662.
909 2009-03-07 Eli Zaretskii <eliz@gnu.org>
911 * function.c (func_shell): Don't close pipedes[1] if it is -1.
912 Fixes Savannah bug #20495.
914 2009-02-28 Ralf Wildenhues <address@hidden>
916 * doc/make.texi (Instead of Execution): Document interaction of
917 -t with phony targets.
919 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
921 Introduce a new keyword "private" which applies to target-specific
922 variables and prevents their values from being inherited.
924 * variable.h (struct variable): Add private_var flag to each variable.
925 Add a flag to specify which list entry switches to the parent target.
926 * variable.c (define_variable_in_set): Initialize private_var flag.

945 2008-09-30 Eli Zaretskii <eliz@gnu.org>
947 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
950 * w32/subproc/build.bat (GCCBuild): Likewise.
952 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
954 * job.c (construct_command_argv_internal): Avoid extra backslash
955 in batch-mode Unixy shells. Under DB_JOBS, display the contents
958 2008-05-31 Eli Zaretskii <eliz@gnu.org>
960 * README.W32.template: Remove obsolete text about non-support for
961 -jN without Unixy shell. Remove obsolete text about not supplying
962 Visual Studio project files (we do supply them). Modify text to
963 prefer GCC builds to MSC builds.
965 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
967 * doc/make.texi (Empty Targets): Fix typo.
969 2008-03-27 Paul Smith <psmith@gnu.org>

982 `value' field is NULL.
984 2007-12-22 Eli Zaretskii <eliz@gnu.org>
986 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
988 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
989 (TEXINFOS): Value changed to `doc/make.texi'.
990 (.SUFFIXES): Use .texi instead of .texinfo.
991 (make.info, make.dvi): Depend on doc/make.texi.
992 (.texi.info): New target, instead of ".texinfo.info". Change -I
993 switch to $(MAKEINFO) to look in doc/. Use --no-split.
994 (.texi): New target, instead of ".texinfo". Change -I switch to
995 $(MAKEINFO) to look in doc/. Use --no-split.
996 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
997 switch to $(MAKEINFO) to look in doc/.
998 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
999 "*.i[0-9][0-9]" (due to --no-split above).
1000 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1001 (html, make_1.html): New targets.
1002 (.PHONY): Add "html".
1003 (.SUFFIXES): Add .html.
1005 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1007 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1008 HAVE_DECL_SYS_SIGLIST.
1010 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1011 build does not use child_execute_job.
1013 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1014 export the SHELL environment variable to the child.
1016 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1018 * config.h.W32: Include sys/types.h.
1019 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1021 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1022 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1025 2007-11-04 Paul Smith <psmith@gnu.org>
1027 * doc/make.texi: Convert references to "commands", "command
1028 lines", and "command script" to "recipe".
1030 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1033 2007-10-27 Bruno Haible <bruno@clisp.org>
1035 * remake.c (f_mtime): Print time difference values between 100 and
1036 ULONG_MAX in fixed-point notation rather than in exponention notation.
1038 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1040 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1041 a more complex value than a simple shell: if it's not a default
1042 shell now then expand it and see if is a default shell then.
1044 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1046 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1047 pathnames, with const strings.
1048 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1049 from the template (used for building from CVS, not a dist).
1051 2007-10-10 Paul Smith <psmith@gnu.org>
1053 * make.h: Add a prototype for w32_kill() (change suggested by
1054 Yongwei Wu <wuyongwei@gmail.com>).
1056 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1058 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1059 directories in Path.
1061 2007-09-12 Paul Smith <psmith@gnu.org>
1063 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1064 Provided by Diego Biurrun <diego@biurrun.de>
1065 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1066 Provided by Diego Biurrun <diego@biurrun.de>
1068 2007-09-11 Paul Smith <psmith@gnu.org>
1070 * doc/make.texi (Special Variables): Moved this into the "How to
1071 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1072 (MAKEFILE_LIST) No longer a section; this was added into the
1073 "Special Variables" section.
1074 (Rule Introduction): Reference .RECIPEPREFIX.
1075 (Simple Makefile): Ditto.
1076 (Rule Syntax): Ditto.
1077 (Command Syntax): Ditto.
1078 (Error Messages): Ditto.
1080 2007-09-10 Paul Smith <psmith@gnu.org>
1082 * commands.c (print_commands): Don't print an extra line in the
1083 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1085 * read.c (construct_include_path): Add the full string to the cache; we
1086 were chopping the last char.
1088 * NEWS: Announce the .RECIPEPREFIX special variable.
1089 * variable.c (lookup_special_var): Rename from handle_special_var().
1090 (lookup_variable): Call the new name.
1091 (set_special_var): New function: handle setting of special variables.
1092 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1093 (do_variable_definition): Call it.
1094 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1095 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1096 * main.c (main): Create the .RECIPEPREFIX special variable.
1097 * read.c (eval): Remove the cmd_prefix characters from the command
1098 scripts here, so they're not stored in the commands array at all,
1099 rather than waiting and stripping them out during command construction.
1100 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1102 2007-08-15 Paul Smith <psmith@gnu.org>
1104 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1105 file has had the section info removed, so add some to make.texi
1106 before we include it.
1108 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1110 * remake.c (check_dep): Reset the target state for intermediate
1111 files. They might have been considered before but not updated
1112 then (order-only for example) but they will be this time.
1113 Fixes Savannah bug #'s 3330 and 15919.
1115 2007-07-21 Eli Zaretskii <eliz@gnu.org>

1118 * function.c (func_shell): Call construct_command_argv with zero
1120 * job.c (construct_command_argv_internal): New argument FLAGS; all

1126 2007-07-13 Paul Smith <psmith@gnu.org>
1128 * file.c (expand_deps): Use variable_buffer as the start of the
1129 buffer, not the original pointer (in case it was reallocated).
1130 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1131 Fixes Savannah bug #20452.
1133 2007-07-04 Paul Smith <psmith@gnu.org>

1148 Fixes Savannah bug #20018.
1150 * expand.c (variable_expand_for_file): Preserve the value of
1151 reading_file rather than setting it to 0 at the end.
1152 Fixes Savannah bug #20033.
1154 2007-05-11 Paul Smith <psmith@gnu.org>
1156 * job.c (new_job): Add debug info to specify where make found the
1157 command script it is running to build a target.
1158 Fixes Savannah bug #18617.
1160 * default.c (default_suffixes,default_suffix_rules,default_variables):
1161 Add support for Objective C. Fixes Savannah bug #16389.
1162 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1164 * function.c (func_lastword): Initialize p.
1166 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1167 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1168 Dave Korn <dave.korn@artimi.com>
1170 2007-05-08 Paul Smith <psmith@gnu.org>
1172 Fix Savannah bug #19656:
1174 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1176 * make.h: Change all case-insensitive string compares to use
1177 strcasecmp() (from POSIX). If we don't have that but do have one
1178 of the others, define strcasecmp to be one of those instead. If
1179 we don't have any, declare a prototype for our own version.
1181 * misc.c (strcasecmp): Use this if we can't find any native
1182 case-insensitive string comparison function.
1183 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1184 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1186 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1187 strcasecmp() instead of stricmp().
1188 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1189 instead of strcmpi().
1190 * acinclude.m4: Remove the strcasecmp() check from here.
1192 2007-03-21 Paul Smith <psmith@gnu.org>
1194 * configure.in: Don't turn on case-insensitive file system support
1195 if --disable-... is given. Fixes Savannah bug #19348.
1197 2007-03-19 Paul Smith <psmith@gnu.org>
1199 * ALL: Use the strcache for all file name strings, or other
1200 strings which we will never free. The goal is to save memory by
1201 avoiding duplicate copies of strings. However, at the moment this
1202 doesn't save much memory in most situations: due to secondary
1203 expansion we actually save prerequisite lists twice (once before
1204 the secondary expansion, and then again after it's been parsed
1205 into individual file names in the dep list). We will resolve this
1206 in a future change, by doing the parsing up-front for targets
1207 where secondary expansion is not set.
1209 Moving things into the strcache also allows us to use const
1210 pointers in many more places.
1212 2007-01-03 Paul Smith <psmith@gnu.org>
1214 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1215 the function, not just the first. Fixes Savannah bug #18680.
1217 2006-11-18 Paul Smith <psmith@gnu.org>
1219 * strcache.c (strcache_add_len): Don't allocate a new buffer
1220 unless the string is not already nil-terminated. Technically this
1221 is a violation of the standard, since we may be passed an array
1222 that is not long enough to test one past. However, in make this
1223 is never true since we only use nil-terminated strings or
1224 sub-strings thereof.
1226 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1228 * main.c: New global cmd_prefix, defaults to '\t'.
1229 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1232 * dir.c: Constified.
1233 (dir_contents_file_exists_p): Check for an error return from
1234 readdir(), just in case.
1236 * commands.c: Constified.
1237 * default.c: Constified.
1238 * expand.c: Constified.
1239 * function.c: Partial constification.
1240 * variable.c: Partial constification.
1241 * vmsify.c: Constification. Hard to test this but I hope I didn't
1243 * vpath.c: Partial constification.
1244 * w32/pathstuff.c: Partial constification.
1246 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1248 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1249 backslashes and drive letters as absolute.
1251 2006-10-22 Paul Smith <psmith@gnu.org>
1253 * main.c (struct command_switch): Use const and void*.
1255 2006-10-21 Paul Smith <psmith@gnu.org>
1258 * arscan.c: Constified.
1260 2006-09-30 Paul Smith <psmith@gnu.org>
1262 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1263 point to lastword since the example was updated.
1264 Fixes Savannah bug #16304.
1265 (Secondary Expansion): Correct example description.
1266 Fixes Savannah bug #16468.
1267 (Makefile Contents): Clarify that comments cannot appear within
1268 variable references or function calls.
1269 Fixes Savannah bug #16577.
1270 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1271 Fixes Savannah bug #17701.
1272 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1273 (Prerequisite Types): Added an example of using order-only
1274 prerequisites. Fixes Savannah bug #17880.
1275 (Rule Syntax): "lise" -> "list"
1276 (Multiple Rules): ... -> @dots{}
1277 (Splitting Lines): ditto.
1279 * remake.c (update_file_1): Prereqs that don't exist should be
1280 considered changed, for the purposes of $?.
1281 Fixes Savannah bug #16051.
1283 * make.1: Remove extraneous "+".
1284 Fixes Savannah bug #16652.

1320 2006-04-20 Paul D. Smith <psmith@gnu.org>
1322 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1323 that don't have extended grep.
1324 (cvsclean): Use $(PERL) instead of perl.
1326 2006-04-09 Paul D. Smith <psmith@gnu.org>
1328 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1330 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1331 inner-scope variables don't mask outer-scope variables.
1333 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1334 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:

1336 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1337 values from memory allocation functions: they return void* and so
1338 don't need to be cast. Also remove (char *) casts of arguments to

1372 Version 3.81 released.
1374 * NEWS: Updated for 3.81.
1376 * README.cvs: Mention that vpath builds are not supported out of
1377 CVS. Fixes Savannah bug #16236.
1378 Remove update of make.texi from the list of things to do; we use

1388 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1389 with lastslash, since the latter points to filename, not to

1392 Declare and define sh_chars_sh[].
1394 2006-03-23 Paul D. Smith <psmith@gnu.org>
1396 * configure.in: Look for build.sh.in in $srcdir so it will be
1397 built for remote configurations as well.
1399 * Makefile.am: Make sure to clean up build.sh during distclean.
1400 Fixes Savannah bug #16166.
1402 * misc.c (log_access): Takes a const char *.
1403 * function.c (fold_newlines): Takes an unsigned int *.
1404 Both fixes for Savannah bug #16170.
1406 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1408 * implicit.c (pattern_search): Call set_file_variables only
1409 if we have prerequisites that need second expansion. Fixes
1410 Savannah bug #16140.
1412 2006-03-19 Paul D. Smith <psmith@gnu.org>
1414 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1415 memory on hosts that don't support it directly.
1417 * README.cvs: Add information on steps for making a release (to
1418 make sure I don't forget any).
1420 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1422 (die): Cleanup code was removed from here; call the new function.
1423 (main): If we are re-execing, clean up the jobserver first so we
1424 don't leak file descriptors.

1430 allow multiple concurrent runs.
1431 Patch from Joseph Myers <joseph@codesourcery.com>
1433 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1436 * misc.c (alloc_dep, free_dep): New functions.
1437 (copy_dep_chain): Copy stem.
1438 (free_dep_chain): Use free_dep.
1439 * read.c (record_files): Store stem in the dependency line.
1440 * file.c (expand_deps): Use stem stored in the dependency line. Use
1441 free_dep_chain instead of free_ns_chain.
1442 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1443 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1444 * main.c (main, handle_non_switch_argument): Ditto.

1453 (allocated_variable_append): Don't expand the final result.
1454 Fixes Savannah bug #15913.
1456 2006-03-09 Paul Smith <psmith@gnu.org>
1458 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1459 listed non-existent files as changed. Turns out there's a bug in
1460 the Linux kernel builds which means that this change causes
1461 everything to rebuild every time. We will re-introduce this fix
1462 in the next release, to give them time to fix their build system.
1463 Fixes Savannah bug #16002.
1464 Introduces Savannah bug #16051.
1466 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1479 to be null; don't core in that case.
1481 2006-02-19 Paul D. Smith <psmith@gnu.org>
1483 * commands.c (set_file_variables): Realloc, not malloc, the static
1484 string values to avoid memory leaks.
1486 * expand.c (recursively_expand_for_file): Only set reading_file to
1487 an initialized value.
1489 * implicit.c (pattern_search): We need to make a copy of the stem
1490 if we get it from an intermediate dep, since those get freed.
1492 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1494 (enter_file) [VMS]: Ditto.
1495 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1499 * job.c (construct_command_argv_internal): Fix last change.
1501 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1502 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1503 the calls to _beginthreadex.
1505 * expand.c (recursively_expand_for_file): Initialize `save' to
1506 prevent compiler warnings.
1508 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1510 * job.c (construct_command_argv_internal): Don't create a temporary
1511 script/batch file if we are under -n. Call _setmode to switch the
1512 script file stream to text mode.
1514 2006-02-17 Paul D. Smith <psmith@gnu.org>
1516 * variable.c (merge_variable_set_lists): Don't try to merge the
1517 global_setlist. Not only is this useless, but it can lead to
1518 circularities in the linked list, if global_setlist->next in one
1519 list gets set to point to another list which also ends in
1521 Fixes Savannah bug #15757.
1523 2006-02-15 Paul D. Smith <psmith@gnu.org>
1525 Fix for Savannah bug #106.
1527 * expand.c (expanding_var): Keep track of which variable we're
1528 expanding. If no variable is being expanded, it's the same as
1530 * make.h (expanding_var): Declare it.
1531 * expand.c (recursively_expand_for_file): Set expanding_var to the
1532 current variable we're expanding, unless there's no file info in
1533 it (could happen if it comes from the command line or a default
1534 variable). Restore it before we exit.

1546 * read.c (eval): Even if the included filenames expands to the
1547 empty string we still need to free the allocated buffer.
1549 * implicit.c (pattern_search): If we allocated a variable set for
1550 an impossible file, free it.
1551 * variable.c (free_variable_set): New function.
1552 * variable.h: Declare it.
1554 * read.c (read_all_makefiles): Makefile names are kept in the
1555 strcache, so there's never any need to alloc/free them.
1558 * main.c (main): Add "archives" to the .FEATURES variable if
1559 archive support is enabled.
1560 * doc/make.texi (Special Variables): Document it.
1562 2006-02-13 Paul D. Smith <psmith@gnu.org>

1570 * (ALL FILES): Updated copyright and license notices.
1572 2006-02-10 Paul D. Smith <psmith@gnu.org>
1574 A new internal capability: the string cache is a read-only cache
1575 of strings, with a hash table interface for fast lookup. Nothing
1576 in the cache will ever be freed, so there's no need for reference
1577 counting, etc. This is the beginning of a full solution for
1578 Savannah bug #15182, but for now we only store makefile names here.
1580 * strcache.c: New file. Implement a read-only string cache.
1581 * make.h: Add prototypes for new functions.
1582 * main.c (initialize_global_hash_tables): Initialize the string cache.
1583 (print_data_base): Print string cache stats.
1584 * read.c (eval_makefile): Use the string cache to store makefile
1585 names. Rewrite the string allocation to be sure we free everything.

1589 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1590 directory time stamp didn't change, except on FAT filesystems.
1591 Suggested by J. David Bryan <jdbryan@acm.org>.

1595 * function.c (func_or): Implement a short-circuiting OR function.
1596 (func_and): Implement a short-circuiting AND function.
1597 (function_table_init): Update the table with the new functions.
1598 * doc/make.texi (Conditional Functions): Changed the "if" section
1599 to one on general conditional functions. Added documentation for
1600 $(and ...) and $(or ...) functions.
1601 * NEWS: Note new $(and ...) and $(or ...) functions.
1603 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1605 * job.h (struct child): Add the dontcare bitfield.
1606 * job.c (new_job): Cache dontcare flag.
1607 * job.c (reap_children): Use cached dontcare flag instead of the
1608 one in struct file. Fixes Savannah bug #15641.
1610 2006-02-06 Paul D. Smith <psmith@gnu.org>
1612 * vpath.c (selective_vpath_search): If the file we find has a
1613 timestamp from -o or -W, use that instead of the real time.
1614 * remake.c (f_mtime): If the mtime is a special token from -o or
1615 -W, don't overwrite it with the real mtime.
1616 Fixes Savannah bug #15341.
1618 Updates from Markus Mauhart <qwe123@chello.at>:
1620 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1621 (process_signal, process_last_err, process_exit_code): Manage
1622 invalid handle values.
1623 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1624 manage invalid handles; remove them.
1625 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1626 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1627 * README.cvs: Updates for building from CVS.
1629 2006-02-05 Paul D. Smith <psmith@gnu.org>
1631 * file.c (enter_file): Keep track of the last double_colon entry,
1632 to avoid walking the list every time we want to add a new one.
1633 Fixes Savannah bug #15533.
1634 * filedef.h (struct file): Add a new LAST pointer.
1636 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1637 the comparison. For 64-bits systems the result of the subtraction
1638 might not fit into an int. Use comparison instead.
1639 Fixes Savannah bug #15534.
1641 * doc/make.texi: Update the chapter on writing commands to reflect
1642 the changes made in 3.81 for backslash/newline and SHELL handling.
1644 2006-02-01 Paul D. Smith <psmith@gnu.org>
1646 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1660 * prepare_w32.bat: Remove this file from the distribution.
1662 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1664 * remake.c (update_goal_chain): Set g->changed instead of
1665 incrementing it, as it is only 8-bit wide, and could overflow if
1666 many commands got started in update_file.
1668 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1670 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1671 MAXIMUM_WAIT_OBJECTS.
1672 (process_wait_for_any_private): Change dimension of handles[]
1673 array to MAXIMUM_WAIT_OBJECTS.
1674 (process_used_slots): New function.
1675 (process_register): Don't register more processes than the
1676 available number of slots.
1677 (process_easy): Don't start new processes if all slots are used up.
1679 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1680 are already more children than sub_proc.c can handle, behave as if
1681 the load were too high.
1682 (start_job_command): Fix a typo in error message when process_easy
1685 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1687 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1688 the shell is not sh.exe.
1690 * job.c (create_batch_file): Renamed from create_batch_filename;
1691 all callers changed. Don't close the temporary file; return its
1692 file descriptor instead. New arg FD allows to return the file
1694 (construct_command_argv_internal): Use _fdopen instead of fopen to
1695 open the batch file.
1697 2006-01-04 Paul D. Smith <psmith@gnu.org>
1699 * readme.vms: Updates for case-insensitive VMS file systems from
1700 Hartmut Becker <Hartmut.Becker@hp.com>.
1701 * dir.c (vms_hash): Ditto.
1702 * vmsify.c (copyto): Ditto.

1709 2006-01-03 Paul D. Smith <psmith@gnu.org>
1711 * remake.c (update_file_1): Mark a prerequisite changed if it
1714 * read.c (eval): Be sure to strip off trailing whitespace from the
1715 prerequisites list properly. Also, initialize all fields in
1716 struct dep when creating a new one.
1718 2005-12-28 Paul D. Smith <psmith@gnu.org>
1720 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1721 disable warnings for MSC.
1722 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1724 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1726 * doc/make.texi (Execution): Add a footnote about changes in
1727 handling of backslash-newline sequences. Mention the differences
1728 on MS-DOS and MS-Windows.
1730 * NEWS: More details about building the MinGW port and a pointer
1731 to README.W32. Fix the section name that describes the new
1732 backward-incompatible processing of backslash-newline sequences.
1733 The special processing of SHELL set to "cmd" is only relevant to
1734 MS-Windows, not MS-DOS.
1736 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1738 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1739 to DWORD, to avoid compiler warnings.
1740 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1741 use %ld in format, to avoid compiler warnings.
1743 * doc/make.texi (Special Targets): Fix a typo.
1744 (Appending): Fix cross-reference to Setting.
1745 (Special Variables, Secondary Expansion, File Name Functions)
1746 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1747 periods after a sentence.
1748 (Execution): Add @: after "e.g.".
1749 (Environment): Fix punctuation.
1750 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1751 (Shell Function, Target-specific): Add @: after "vs."
1753 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1755 * read.c (record_target_var): Initialize variable's export field
1756 with v_default instead of leaving it "initialized" by whatever
1757 garbage happened to be on the heap.
1759 2005-12-12 Paul D. Smith <psmith@gnu.org>
1761 * make.1: Fix some display errors and document all existing options.
1762 Patch by Mike Frysinger <vapier@gentoo.org>.
1764 2005-12-11 Paul D. Smith <psmith@gnu.org>
1766 * implicit.c (pattern_search): If 2nd expansion is not set for
1767 this implicit rule, replace the pattern with the stem directly,
1768 and don't re-expand the variable list. Along with the other
1769 .SECONDEXPANSION changes below, fixes bug #13781.
1771 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1773 * implicit.c (pattern_search): Mark other files that this rule
1774 builds as targets so that they are not treated as intermediates
1775 by the pattern rule search algorithm. Fixes bug #13022.
1777 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1779 * remake.c (notice_finished_file): Propagate the change of
1780 modification time to all the double-colon entries only if
1781 it is the last one to be updated. Fixes bug #14334.
1783 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1785 * function.c (func_flavor): Implement the flavor function which
1786 returns the flavor of a variable.
1787 * doc/make.texi (Functions for Transforming Text): Document it.
1788 * NEWS: Add it to the list of new functions.
1790 2005-11-14 Boris Kolpackov <boris@kolpackov.net>

1794 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1795 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1797 2005-10-26 Paul Smith <psmith@gnu.org>
1799 * read.c (record_files): Don't set deps flags if there are no deps.
1800 * maintMakefile: We only need to build the templates when we are
1801 creating a distribution, so don't do it for "all".
1803 2005-10-24 Paul D. Smith <psmith@gnu.org>
1805 Make secondary expansion optional: its enabled by declaring the
1806 special target .SECONDEXPANSION.
1808 * NEWS: Update information on second expansion capabilities.
1809 * doc/make.texi (Secondary Expansion): Document the
1810 .SECONDEXPANSION special target and its behavior.
1811 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1812 prerequisite list was found in a static pattern rule.
1813 (free_dep_chain): Declare a prototype.
1814 * file.c (parse_prereqs): New function: break out some complexity
1816 (expand_deps): If we aren't doing second expansion, replace % with
1817 the stem for static pattern rules. Call the new function.
1818 * filedef.h (parse_prereqs): Declare a prototype.
1819 * implicit.c (pattern_search): Initialize the new staticpattern
1821 * main.c (second_expansion): Declare a global variable to remember
1822 if the special target has been seen. Initialize the new
1823 staticpattern field for prerequisites.
1824 * make.h: Extern for second_expansion.
1825 * misc.c (free_dep_chain): New function: frees a struct dep list.
1826 * read.c (read_all_makefiles): Initialize the staticpattern field.
1827 (eval_makefile): Ditto.
1828 (record_files): Check for the .SECONDEXPANSION target and set
1829 second_expansion global if it's found.
1830 Use the new free_dep_chain() instead of doing it by hand.
1831 Set the staticpattern field for prereqs of static pattern targets.
1833 2005-10-16 Paul D. Smith <psmith@gnu.org>
1835 * main.c (main): Set CURDIR to be a file variable instead of a
1836 default, so that values of CURDIR inherited from the environment
1837 won't override the make value.
1839 2005-09-26 Paul D. Smith <psmith@gnu.org>
1841 * job.c (construct_command_argv_internal): If the line is empty
1842 remember to free the temporary argv strings.
1845 2005-09-16 Paul D. Smith <psmith@gnu.org>
1847 * job.c (start_job_command): The noerror flag is a boolean (single
1848 bit); set it appropriately.
1849 Reported by Mark Eichin <eichin@metacarta.com>
1851 2005-08-29 Paul D. Smith <psmith@gnu.org>
1853 * function.c (func_error): On Windows, output from $(info ...)
1854 seems to come in the wrong order. Try to force it with fflush().
1856 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1858 * read.c (record_files): Move code that sets stem for static
1859 pattern rules out of the if (!two_colon) condition so it is
1860 also executed for two-colon rules. Fixes Savannah bug #13881.
1862 2005-08-08 Paul D. Smith <psmith@gnu.org>
1864 * make.h: Don't test that __STDC__ is non-0. Some compilers
1865 (Windows for example) set it to 0 to denote "ISO C + extensions".
1868 2005-08-07 Paul D. Smith <psmith@gnu.org>
1870 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1871 conditional (slightly different version of a fix from Eli).
1873 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1874 If make is running in parallel without -k and two jobs die in a
1875 row, but not too close to each other, then make will quit without
1876 waiting for the rest of the jobs to die.
1878 * main.c (die): Don't reset err before calling reap_children() the
1879 second time: we still want it to be in the error condition.
1880 * job.c (reap_children): Use a static variable, rather than err,
1881 to control whether or not the error message should be printed.
1883 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1885 * w32/subproc/sub_proc.c: Include signal.h.
1886 (process_pipe_io, process_file_io): Pass a pointer to a local
1887 DWORD variable to GetExitCodeProcess. If the exit code is
1888 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1890 * job.c [WINDOWS32]: Include windows.h.
1891 (main_thread) [WINDOWS32]: New global variable.
1892 (reap_children) [WINDOWS32]: Get the handle for the main thread
1893 and store it in main_thread.
1895 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1896 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1897 doing anything else. When we are done, close the main thread
1898 handle and exit with status 130.
1900 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1902 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1905 * main.c (find_and_set_default_shell): If found a DOSish shell,
1906 set sh_found and the value of default_shell, and report the
1907 findings in debug mode.
1909 * job.c (construct_command_argv_internal): Check unixy_shell, not
1910 no_default_sh_exe, to decide whether to use Unixy or DOSish
1913 * README.W32: Update with info about the MinGW build.
1915 * build_w32.bat: Support MinGW.
1917 * w32/subproc/build.bat: Likewise.
1919 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1920 printing DWORD args.
1922 * function.c (windows32_openpipe): Fix format strings for printing
1925 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1927 (start_job_command): Fix format string for printing the result of
1929 (start_job_command) [WINDOWS32]: Do not define.
1930 (exec_command): Fix format string for printing HANDLE args.
1932 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1933 to avoid compiler warnings.
1934 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1935 (Note: some of these fixes were submitted independently by J. Grant)
1937 2005-07-30 J. Grant <jg@jguk.org>
1939 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1940 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1941 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1943 2005-07-15 Paul Smith <psmith@gnu.org>
1945 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1946 we don't have a POSIX shell, then revert to the old
1947 backslash-newline behavior (where they are stripped).
1950 2005-07-08 Paul D. Smith <psmith@gnu.org>
1952 * config.h.W32.template: Reorder to match the standard config.h,
1953 for easier comparisons.
1954 From J. Grant <jg@jguk.org>
1956 * maintMakefile: Remove .dep_segment before overwriting it, in
1957 case it's not writable or noclobber is set.
1958 * expand.c (variable_expand_string): Cast result of pointer
1959 arithmetic to avoid a warning.
1960 * main.c (switches): Add full-fledged final initializer.
1962 2005-07-06 Paul D. Smith <psmith@gnu.org>
1964 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1965 * signame.c (strsignal): If we found _sys_siglist[] or
1966 __sys_siglist[] use those instead of sys_siglist[].
1967 From Albert Chin <china@thewrittenword.com>
1969 2005-07-04 Paul D. Smith <psmith@gnu.org>
1971 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1972 globfree(); set up to use the GNU versions.
1973 From Martin Zinser <zinser@zinser.no-ip.info>
1975 2005-07-03 Paul D. Smith <psmith@gnu.org>
1977 From J. Grant <jg@jguk.org>:
1979 * README.W32.template: Update the Windows and tested MSVC versions.
1980 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1981 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1982 * build_w32.bat: Ditto.
1983 * w32/subproc/build.bat: Ditto.
1985 2005-06-28 Paul D. Smith <psmith@gnu.org>
1987 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1988 declaration was checked but not present.
1990 2005-06-27 Paul D. Smith <psmith@gnu.org>
1992 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1993 to unsigned long. Fixes Savannah bug #13550.
1995 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1996 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1997 Fixes Savannah bug #13551.
1999 2005-06-26 Paul D. Smith <psmith@gnu.org>
2001 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2002 it if ANSI_STRING is not set.
2004 2005-06-25 Paul D. Smith <psmith@gnu.org>
2006 * read.c (eval): If no filenames are passed to any of the
2007 "include" variants, don't print an error.
2008 * doc/make.texi (Include): Document this.
2009 Fixes Savannah bug #1761.
2011 * job.c (construct_command_argv_internal): Sanitize handling of
2012 backslash/newline pairs according to POSIX: that is, keep the
2013 backslash-newline in the command script, but remove a following
2014 TAB character, if present. In the fast path, make sure that the
2015 behavior matches what the shell would do both inside and outside
2016 of quotes. In the slow path, quote the backslash and put a
2017 literal newline in the string.
2018 Fixes Savannah bug #1332.
2019 * doc/make.texi (Execution): Document the new behavior and give
2021 * NEWS: Make a note of the new behavior.
2023 * make.h [WINDOWS32]: #include <direct.h>.
2024 Fixes Savannah bug #13478.
2026 * remake.c (name_mtime): If the stat() of a file fails and the -L
2027 option was given and the file is a symlink, take the best mtime of
2028 the symlink we can get as the mtime of the file and don't fail.
2029 Fixes Savannah bug #13280.
2031 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2032 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2033 inside a variable reference. Make this function static as it's
2035 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2036 parsing an unexpanded line looking for semicolons.
2037 Fixes Savannah bug #1454.
2038 * misc.c (remove_comments): Move this to read.c and make it static
2039 as it's only used there. Call find_char_unquote() with new arg.
2040 * make.h: Remove prototypes for find_char_unquote() and
2041 remove_comments() since they're static now.
2043 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2044 its export flag and obtain its value. When we need to re-exec,
2045 increment the value and add it into the environment.
2046 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2047 * NEWS: Mention MAKE_RESTARTS.
2048 * main.c (always_make_set): New variable. Change the -B option to
2049 set this one instead.
2050 (main): When checking makefiles, only set always_make_flag if
2051 always_make_set is set AND the restarts flag is 0. When building
2052 normal targets, set it IFF always_make_set is set.
2053 (main): Avoid infinite recursion with -W, too: only set what-if
2054 files to NEW before we check makefiles if we've never restarted
2055 before. If we have restarted, set what-if files to NEW _after_ we
2057 Fixes Savannah bug #7566:
2059 2005-06-17 Paul D. Smith <psmith@gnu.org>
2061 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2062 in the prerequisites list.
2064 2005-06-12 Paul D. Smith <psmith@gnu.org>
2066 Fix Savannah bug # 1328.
2068 * configure.in: Check for atexit().
2069 * misc.c (close_stdout): Test stdout to see if writes to it have
2070 failed. If so, be sure to exit with a non-0 error code. Based on
2071 code found in gnulib.
2072 * make.h: Prototype.
2073 * main.c (main): Install close_stdout() with atexit().
2075 2005-06-10 Paul D. Smith <psmith@gnu.org>
2077 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2079 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2080 headers; make vmsWaitForChildren() static; extern vmsify().
2081 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2082 Don't create child_execute_job() here (it's in vmsjobs.c).
2083 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2085 2005-06-09 Paul D. Smith <psmith@gnu.org>
2087 * variable.c (push_new_variable_scope): File variables point
2088 directly to the global_setlist variable. So, inserting a new
2089 scope in front of that has no effect on those variables: they
2090 don't go through current_variable_set_list. If we're pushing a
2091 scope and the current scope is global, push it "the other way" so
2092 that the new setlist is in the global_setlist variable, and
2093 next points to a new setlist with the global variable set.
2094 (pop_variable_scope): Properly undo a push with the new
2096 Fixes Savannah bug #11913.
2098 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2100 * job.c (reap_children): Don't die of the command failed but
2101 the dontcare flag is set. Fixes Savannah bug #13216.
2103 * implicit.c (pattern_search): When creating a target from
2104 an implicit rule match, lookup pattern target and set precious
2105 flag in a newly created target. Fixes Savannah bug #13218.
2107 2005-05-13 Paul D. Smith <psmith@gnu.org>
2109 Implement "if... else if... endif" syntax.
2111 * read.c (eval): Push all checks for conditional words ("ifeq",
2112 "else", etc.) down into the conditional_line() function.
2113 (conditional_line): Rework to allow "else if..." clause. New
2114 return value -2 for lines which are not conditionals. The
2115 ignoring flag can now also be 2, which means "already parsed a
2116 true branch". If that value is seen no other branch of this
2117 conditional can be considered true. In the else parsing if there
2118 is extra text after the else, invoke conditional_line()
2119 recursively to see if it's another conditional. If not, it's an
2120 error. If so, raise the conditional value to this level instead
2121 of creating a new conditional nesting level. Special check for
2122 "else" and "endif", which aren't allowed on the "else" line.
2123 * doc/make.texi (Conditional Syntax): Document the new syntax.
2125 2005-05-09 Paul D. Smith <psmith@gnu.org>
2127 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2128 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2129 recurses to the w32 directory, even on non-Windows systems. Use
2130 the method suggested in the automake manual.
2131 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2132 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2134 2005-05-07 Paul D. Smith <psmith@gnu.org>
2136 * main.c (die): If we're dying with a fatal error (not that a
2137 command has failed), write back any leftover tokens before we go.
2139 * job.c (set_child_handler_action_flags): If there are jobs
2140 waiting for the load to go down, set an alarm to go off in 1
2141 second. This allows us to wake up from a potentially long-lasting
2142 read() and start a new job if the load has gone down. Turn it off
2144 (job_noop): Dummy signal handler function.
2145 (new_job): Invoke it with the new semantics.
2147 * docs/make.texi: Document secondary expansion. Various cleanups
2150 2005-05-03 Paul D. Smith <psmith@gnu.org>
2152 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2153 the targets which are to ultimately be made are called "goals";
2154 see the GNU make manual. Also, MAKECMDGOALS, etc.
2156 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2157 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2158 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2160 2005-05-02 Paul D. Smith <psmith@gnu.org>
2162 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2163 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2164 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2165 functions to vmsjobs.c. #include it into jobs.c.
2167 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2168 jobserver tokens. I found that this happens when an exported
2169 recursive variable contains a $(shell ...) function reference: in
2170 this situation we could "forget" to write back a token.
2172 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2173 we have. It's not reliable to depend on the number of children in
2174 our linked list so keep a separate count.
2175 (new_job): Check jobserver_tokens rather than children &&
2176 waiting_jobs. Increment jobserver_tokens when we get one.
2177 (free_child): If jobserver_tokens is 0, internal error. If it's
2178 >1, write a token back to the jobserver pipe (we don't write a
2179 token for the "free" job). Decrement jobserver_tokens.
2181 * main.c: Add variable master_job_slots.
2182 (main): Set it to hold the number of jobs requested if we're the
2183 master process, when using the jobserver.
2184 (die): Sanity checks: first test jobserver_tokens to make sure
2185 this process isn't holding any tokens we didn't write back.
2186 Second, if master_job_slots is set count the tokens left in the
2187 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2189 2005-04-24 Paul D. Smith <psmith@gnu.org>
2191 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2192 with -l# can lose jobserver tokens, because waiting jobs are not
2193 consulted properly when checking for the "free" token.
2195 * job.c (free_child): Count waiting_jobs as having tokens.
2196 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2197 handle jobs waiting for the load to drop.
2199 2005-04-23 Paul D. Smith <psmith@gnu.org>
2201 * main.c (main): Be careful to not core if a variable setting in
2202 the environment doesn't contain an '='. This is illegal but can
2203 happen in broken setups.
2204 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2206 2005-04-12 Paul D. Smith <psmith@gnu.org>
2208 The second expansion feature causes significant slowdown. Timing
2209 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2210 read the makefile before the feature, to 11+s to do the same
2211 operations after the feature. Additionally, memory usage
2212 increased drastically. To fix this I added some intelligence that
2213 avoids the overhead of the second expansion unless it's required.
2215 * dep.h: Add a new boolean field, need_2nd_expansion.
2217 * read.c (eval): When creating the struct dep for the target,
2218 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2219 (record_files): If there's a "%" in a static pattern rule, it gets
2220 converted to "$*" so set need_2nd_expansion to 1.
2222 * file.c (expand_deps): Rework to be more efficient. Only perform
2223 initialize_file_variables(), set_file_variables(), and
2224 variable_expand_for_file() if the need_2nd_expansion is set.
2226 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2227 (pattern_search): Ditto.
2228 * main.c (handle_non_switch_argument): Ditto.
2230 * read.c (read_all_makefiles): Ditto.
2231 (eval_makefile): Ditto.
2233 2005-04-07 Paul D. Smith <psmith@gnu.org>
2235 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2236 * variable.c (sync_Path_environment): Ditto.
2237 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2239 * main.c (main): Define the .FEATURES variable.
2240 * NEWS: Announce .FEATURES.
2241 * doc/make.texi (Special Variables): Document .FEATURES.
2243 * remake.c (check_dep): If a file is .PHONY, update it even if
2244 it's marked intermediate. Fixes Savannah bug #12331.
2246 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2248 * file.c (expand_deps): Factor out the second expansion and
2249 prerequisite line parsing logic from snap_deps().
2251 * file.c (snap_deps): Use expand_deps(). Expand and parse
2252 prerequisites of the .SUFFIXES special target first. Fixes
2253 Savannah bug #12320.
2255 2005-03-13 Paul D. Smith <psmith@gnu.org>
2257 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2260 2005-03-11 Paul D. Smith <psmith@gnu.org>
2262 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2263 available, not undefined (from Earnie Boyd).
2265 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2267 * implicit.c (pattern_search): Mark an intermediate target as
2268 precious if it happened to be a prerequisite of some (other)
2269 target. Fixes Savannah bug #12267.
2271 2005-03-09 Paul D. Smith <psmith@gnu.org>
2273 * read.c (eval_makefile): Add alloca(0).
2274 (eval_buffer): Ditto.
2276 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2278 * main.c (main): Use o_file instead of o_default when defining
2279 the .DEFAULT_TARGET special variable.
2280 * read.c (eval): Use define_variable_global() instead of
2281 define_variable() when setting new value for the .DEFAULT_TARGET
2282 special variable. Fixes Savannah bug #12266.
2284 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2286 * imlicit.c (pattern_search): Mark files for which an implicit
2287 rule has been found as targets. Fixes Savannah bug #12202.
2289 2005-03-04 Paul D. Smith <psmith@gnu.org>
2292 * doc/make.texi (Automatic Variables): Document $|.
2294 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2296 * read.c (record_files): Instead of substituting % with
2297 actual stem value in dependency list replace it with $*.
2298 This fixes stem triple expansion bug.
2300 * implicit.c (pattern_search): Copy stem to a separate
2301 buffer and make it a properly terminated string. Assign
2302 this buffer instead of STEM (which is not terminated) to
2303 f->stem. Instead of substituting % with actual stem value
2304 in dependency list replace it with $*. This fixes stem
2305 triple expansion bug.
2307 2005-03-01 Paul D. Smith <psmith@gnu.org>
2309 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2310 on Windows, as it takes a handle not a pid. Just exit.
2311 Fix from patch #3679, provided by Alessandro Vesely.
2313 * configure.in: Update check for sys_siglist[] from autoconf manual.
2314 * signame.c (strsignal): Update to use the new autoconf macro.
2316 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2318 * read.c (record_files): Add a check for the list of prerequisites
2319 of a static pattern rule being empty. Fixes Savannah bug #12180.
2321 2005-02-28 Paul D. Smith <psmith@gnu.org>
2323 * doc/make.texi (Text Functions): Update docs to allow the end
2324 ordinal for $(wordlist ...) to be 0.
2325 * function.c (func_wordlist): Fail if the start ordinal for
2326 $(wordlist ...) is <1. Matches documentation.
2327 Resolves Savannah support request #103195.
2329 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2330 previously we were stopping when !-q, exactly the opposite. This
2331 has been wrong since version 1.34, in 1994!
2332 (update_file): If we got an error don't break out to run more
2333 double-colon rules: just return immediately.
2334 Fixes Savannah bug #7144.
2336 2005-02-27 Paul D. Smith <psmith@gnu.org>
2338 * misc.c (end_of_token): Make argument const.
2339 * make.h: Update prototype.
2341 * function.c (abspath, func_realpath, func_abspath): Use
2342 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2343 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2344 * read.c (record_files): Ditto.
2345 * variable.c (do_variable_definition): Ditto.
2347 * function.c (func_error): Create a new function $(info ...) that
2348 simply prints the message to stdout with no extras.
2349 (function_table_init): Add new function to the table.
2350 * NEWS: Add $(info ...) reference.
2351 * doc/make.texi (Make Control Functions): Document it.
2353 New feature: if the system supports symbolic links, and the user
2354 provides the -L/--check-symlink-time flag, then use the latest
2355 mtime between the symlink(s) and the target file.
2357 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2358 readlink(). If both are available, define MAKE_SYMLINKS.
2359 * main.c: New variable: check_symlink_flag.
2360 (usage): Add a line for -L/--check-symlink-times to the help string.
2361 (switches): Add -L/--check-symlink-times command line argument.
2362 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2363 print a warning and disable it again.
2364 * make.h: Declare check_symlink_flag.
2365 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2366 if the file is a symlink then check each link in the chain and
2367 choose the NEWEST mtime we find as the mtime for the file. The
2368 newest mtime might be the file itself!
2369 * NEWS: Add information about this new feature.
2370 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2372 Avoid core dumps described in Savannah bug # 12124:
2374 * file.c: New variable snapped_deps remember whether we've run
2376 (snap_deps): Set it.
2377 * filedef.h: Extern it.
2378 * read.c (record_files): Check snapped_deps; if it's set then
2379 we're trying to eval a new target/prerequisite relationship from
2380 within a command script, which we don't support. Fatal.
2382 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2384 Implementation of the .DEFAULT_TARGET special variable.
2386 * read.c (eval): If necessary, update default_target_name when
2388 * read.c (record_files): Update default_target_file if
2389 default_target_name has changed.
2390 * main.c (default_target_name): Define.
2391 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2392 default_target_name is set use default_target_file as a root
2394 * filedef.h (default_target_name): Declare.
2395 * dep.h (free_dep_chain):
2396 * misc.c (free_dep_chain): Change to operate on struct nameseq
2397 and change name to free_ns_chain.
2398 * file.c (snap_deps): Update to use free_ns_chain.
2400 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2402 Implementation of the second expansion in explicit rules,
2403 static pattern rules and implicit rules.
2405 * read.c (eval): Refrain from chopping up rule's dependencies.
2406 Store them in a struct dep as a single dependency line. Remove
2407 the code that implements SySV-style automatic variables.
2409 * read.c (record_files): Adjust the code that handles static
2410 pattern rules to expand all percents instead of only the first
2411 one. Reverse the order in which dependencies are stored so that
2412 when the second expansion reverses them again they appear in
2413 the makefile order (with some exceptions, see comments in
2414 the code). Remove the code that implements SySV-style automatic
2417 * file.c (snap_deps): Implement the second expansion and chopping
2418 of dependency lines for explicit rules.
2420 * implicit.c (struct idep): Define an auxiliary data type to hold
2421 implicit rule's dependencies after stem substitution and
2424 * implicit.c (free_idep_chain): Implement.
2426 * implicit.c (get_next_word): Implement helper function for
2427 parsing implicit rule's dependency lines into words taking
2428 into account variable expansion requests. Used in the stem
2431 * implicit.c (pattern_search): Implement the second expansion
2432 for implicit rules. Also fixes bug #12091.
2434 * commands.h (set_file_variables): Declare.
2435 * commands.c (set_file_variables): Remove static specifier.
2437 * dep.h (free_dep_chain): Declare.
2438 * misc.c (free_dep_chain): Implement.
2440 * variable.h (variable_expand_for_file): Declare.
2441 * expand.c (variable_expand_for_file): Remove static specifier.
2443 * make.h (strip_whitespace): Declare.
2444 * function.c (strip_whitespace): Remove static specifier.
2446 2005-02-26 Paul D. Smith <psmith@gnu.org>
2448 * main.c (main): Check for ferror() when reading makefiles from stdin.
2449 Apparently some shells in Windows don't close pipes properly and
2452 2005-02-24 Jonathan Grant <jg@jguk.org>
2454 * configure.in: Add MinGW configuration options, and extra w32 code
2456 * Makefile.am: Add MinGW configuration options, and extra w32 code
2458 * main.c: Determine correct program string (after last \ without .exe).
2459 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2461 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2462 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2463 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2464 environment support.
2466 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2468 * function.c (func_shell): When initializing error_prefix, check
2469 that reading file name is not null. This fixes long-standing
2470 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2472 2005-02-09 Paul D. Smith <psmith@gnu.org>
2474 * maintMakefile: Update the CVS download URL to simplify them.
2475 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2476 downloading the .texi files from Savannah now.
2478 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2480 * main.c (handle_non_switch_argument): Only add variables to
2481 command_variables if they're not already there: duplicate settings
2482 waste space and can be confusing to read.
2484 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2485 this header is never included by non-WINDOWS32 code, and it
2486 requires <config.h> to define which isn't always included first.
2488 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2489 testing MINGW32 versions.
2491 * main.c (log_working_directory): flush stdout to be sure the WD
2492 change is printed before any stderr messages show up.
2494 2005-02-01 Paul D. Smith <psmith@gnu.org>
2496 * maintMakefile (po_repo): Update the GNU translation site URL.
2498 2004-12-01 Paul D. Smith <psmith@gnu.org>
2500 * main.c (main): Change char* env_shell to struct variable shell_var.
2501 * variable.c (target_environment): Use new shell_var.
2503 2004-11-30 Paul D. Smith <psmith@gnu.org>
2505 * configure.in: The old way we avoided creating build.sh from
2506 build.sh.in before build.sh.in exists doesn't work anymore; we
2507 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2508 the help!). This also keeps automake from complaining.
2509 * Makefile.am (README): Add a dummy target so automake won't
2510 complain that this file doesn't exist when we checkout from CVS.
2511 * maintMakefile (.dep_segment): Rewrite this rule since newer
2512 versions of automake don't provide DEP_FILES.
2514 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2516 Implementation of `realpath' and `abspath' built-in functions.
2518 * configure.in: Check for realpath.
2519 * function.c (abspath): Return an absolute file name that does
2520 not contain any `.' or `..' components, nor repeated `/'.
2521 * function.c (func_abspath): For each name call abspath.
2522 * function.c (func_realpath): For each name call realpath
2523 from libc or delegate to abspath if realpath is not available.
2524 * doc/make.texi (Functions for File Names): Document new functions.
2525 * doc/make.texi (Quick Reference): Ditto.
2527 2004-11-28 Paul D. Smith <psmith@gnu.org>
2529 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2530 arguments. Fixes bug #10252.
2532 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2534 * main.c (main): Set SHELL to v_noexport by default. Remember the
2535 original environment setting of SHELL in the env_shell variable.
2536 * main.h: Export new env_shell variable.
2537 * variable.c (target_environment): If we find a v_noexport
2538 variable for SHELL, add a SHELL variable with the env_shell value.
2539 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2540 * doc/make.texi (Variables/Recursion): Ditto.
2542 2004-11-28 Paul D. Smith <psmith@gnu.org>
2544 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2545 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2546 Patch by Alessandro Vesely.
2548 2004-11-12 Paul D. Smith <psmith@gnu.org>
2550 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2551 the command line if it's inside a string.
2552 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2554 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2556 * function.c (func_lastword): New function: return last word
2557 from the list of words.
2558 * doc/make.texi: Document $(lastword ). Fix broken links in
2559 Quick Reference section.
2561 2004-10-06 Paul D. Smith <psmith@gnu.org>
2563 Apply patch from Alessandro Vesely, provided with bug # 9748.
2564 Fix use of tmpnam() to work with Borland C.
2566 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2567 construction of a temporary filename, and call new function
2568 create_batch_filename().
2569 (create_batch_filename) [WINDOWS32]: New function to create a
2572 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2574 * read.c (record_target_var): Expand simple pattern-specific
2576 * variable.c (initialize_file_variables): Do not expand simple
2577 pattern-specific variable.
2579 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2581 * remake.c (update_file_1): When rebuilding makefiles inherit
2582 dontcare flag from a target that triggered update.
2584 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2586 * variable.c (initialize_file_variables): Mark pattern-specific
2587 variable as a per-target and copy export status.
2589 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2591 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2593 * implicit.c (pattern_search): When considering an implicit rule's
2594 prerequisite check that it is actually a target rather then
2595 just an entry in the file hashtable.
2597 2004-09-21 Paul D. Smith <psmith@gnu.org>
2599 * read.c (readstring): Fix some logic errors in backslash handling.
2600 (eval): Remove some unnecessary processing in buffer handling.
2601 (record_target_var): Assert that parse_variable_definition() succeeded.
2602 Reported by: Markus Mauhart <qwe123@chello.at>.
2604 * misc.c: Removed the sindex() function. All instances of this
2605 function were trivially replaceable by the standard strstr()
2606 function, and that function will always have better (or certainly
2607 no worse) performance than the very simple-minded algorithm
2608 sindex() used. This can matter with complex makefiles.
2609 * make.h: Remove the prototype for sindex().
2610 * function.c (subst_expand): Convert sindex() call to strstr().
2611 This means we no longer need to track the TLEN value so remove that.
2612 (func_findstring): Convert sindex() to strstr().
2613 * commands.c (chop_commands): Convert sindex() calls to strstr().
2614 Suggested by: Markus Mauhart <qwe123@chello.at>.
2616 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2617 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2618 If SHELL is set to CMD.EXE then assume it's batch-mode and
2619 non-unixy. I wrote the code differently from the patch, though,
2620 to make it safer. This also resolves bug #9174.
2622 2004-09-20 Paul D. Smith <psmith@gnu.org>
2624 * expand.c (variable_expand_string): Modify to invoke
2625 patsubst_expand() instead of subst_expand(); the latter didn't
2626 handle suffix patterns correctly.
2627 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2628 was used only from variable_expand_string() and is no longer used
2630 (func_subst): Ditto, on call to subst_expand().
2631 (patsubst_expand): Require the percent pointers to point to the
2632 character after the %, not to the % itself.
2633 * read.c (record_files): New call criteria for patsubst_expand().
2634 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2635 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2637 2004-09-19 Paul D. Smith <psmith@gnu.org>
2639 * function.c (subst_expand): Fix a check in by_word: look for a
2640 previous blank if we're beyond the beginning of the string, not
2641 the beginning of the word.
2642 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2644 2004-05-16 Paul D. Smith <psmith@gnu.org>
2646 * remake.c (update_goal_chain): Change the argument specifying
2647 whether we're rebuilding makefiles to be a global variable,
2648 REBUILDING_MAKEFILES.
2649 (complain): Extract the code that complains about no rules to make
2650 a target into a separate function.
2651 (update_file_1): If we tried to rebuild a file during the makefile
2652 rebuild phase and it was dontcare, then no message was printed.
2653 If we then try to build the same file during the normal build,
2654 print a message this time.
2655 (remake_file): Don't complain about un-remake-able files when
2656 we're rebuilding makefiles.
2658 2004-05-11 Paul D. Smith <psmith@gnu.org>
2660 * job.c (construct_command_argv_internal): OS/2 patches from
2661 Andreas Buening <andreas.buening@nexgo.de>.
2663 2004-05-10 Paul D. Smith <psmith@gnu.org>
2665 * remake.c (update_file): Don't walk the double-colon chain unless
2666 this is a double-colon rule. Fix suggested by Boris Kolpackov
2667 <boris@kolpackov.net>.
2669 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2670 * readme.vms: New section describing OpenVMS support and issues.
2671 * default.c (default_variables): Add support for IA64.
2672 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2673 without some privilege aborts make with the error
2674 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2675 pressing Ctrl+Y and the input device is no terminal. The change
2676 catches this error and just continues.
2678 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2680 2004-04-25 Paul D. Smith <psmith@gnu.org>
2682 * commands.c (set_file_variables): Set $< properly in the face of
2683 order-only prerequisites.
2684 Patch from Boris Kolpackov <boris@kolpackov.net>
2686 2004-04-21 Bob Byrnes <byrnes@curl.com>
2688 * main.c (main): Notice failures to remake makefiles.
2690 2004-03-28 Paul D. Smith <psmith@gnu.org>
2692 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2694 * job.c: No default shell for RISC OS.
2695 (load_too_high): Hard-code the return to 1.
2696 (construct_command_argv_internal): No sh_chars or sh_cmds.
2697 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2699 2004-03-20 Paul D. Smith <psmith@gnu.org>
2701 * variable.c (do_variable_definition): Don't append from the
2702 global set if a previous non-appending target-specific variable
2703 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2706 * expand.c (reference_variable): Don't give up on variables with
2707 no value that have the target-specific append flag set: they might
2708 have a value after all. Reported by Oliver Schmidt
2709 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2710 <nikulin@dx1cmd.inp.nsk.su>.
2712 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2713 refer to absolute pathnames in directories that don't exist: some
2714 portion of the makefile could create those directories before we
2715 match the pattern. Fixes bugs #775 and #108.
2717 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2719 * main.c (main): Free makefile_mtimes if we have any.
2720 * README.W32.template: Update documentation for the current status
2721 of the MS-Windows port.
2722 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2723 environment variable is sometimes already defined which causes the
2725 * main.c (debug_signal_handler): Only define this function if
2726 SIGUSR1 is available.
2728 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2730 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2731 * README.OS2.template: Documentation updates.
2732 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2733 link line for safety.
2734 * maintMakefile (build.sh.in): Remove an extraneous ")".
2735 * job.c (child_execute_job): Close saved FDs.
2736 * job.c (exec_command) [OS/2]: exec_command(): If the command
2737 can't be exec'ed and if the shell is not Unix-sh, then try again
2738 with argv = { "cmd", "/c", ... }. Normally, this code is never
2739 reached for the cmd shell unless the command really doesn't exist.
2740 (construct_command_argv_internal) [OS/2]: The code for cmd
2741 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2742 The CMD builtin commands are case insensitive so use strcasecmp().
2744 2004-03-19 Paul D. Smith <psmith@gnu.org>
2746 * read.c (do_define): Re-order line counter increment so the count
2747 is accurate (we were losing one line per define). Reported by
2748 Dave Yost <Dave@Yost.com>.
2750 2004-03-06 Paul D. Smith <psmith@gnu.org>
2752 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2754 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2755 * misc.c (message,error,fatal): Ditto.
2756 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2757 * config.h.W32.template: Ditto.
2758 * config.h-vms.template: Ditto.
2759 * config.ami.template: Ditto.
2761 2004-03-04 Paul D. Smith <psmith@gnu.org>
2763 * README.template: Add a note about broken /bin/sh on SunOS
2764 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2766 * misc.c (message, error, fatal): Don't use "..." if we're using
2767 varargs. ansi2knr should handle this but it doesn't work: it
2768 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2769 done. On many systems (SunOS for example) va_dcl is a #define.
2770 So, force the use of the non-"..." version on pre-ANSI compilers.
2772 * maintMakefile (sign-dist): Create some rules to help automate
2773 the new GNU ftp upload method.
2775 2004-02-24 Paul D. Smith <psmith@gnu.org>
2777 * config.h.W32.template: Add HAVE_STDARG_H
2778 * config.h-vms.template: Ditto.
2779 * config.ami.template: Ditto.
2781 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2783 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2784 * build_w32.bat: Remove extra "+".
2786 2004-02-23 Paul D. Smith <psmith@gnu.org>
2788 * make.h: Create an UNUSED macro to mark unused parameters.
2789 * (many): Clean up warnings by applying UNUSED, fixing
2790 signed/unsigned incompatibilities, etc.
2792 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2794 * filedef.h: Name the command_state enumeration.
2795 * file.c (set_command_state): Use the enumeration in the function
2798 * configure.in: Explicitly set SET_MAKE to empty, to disable
2799 MAKE=make even when no make already exists. Fix bug #3823.
2801 2004-02-22 Paul D. Smith <psmith@gnu.org>
2803 * maintMakefile: Perl script to clean up all non-CVS files. Use
2804 it on all the subdirectories for the cvs-clean target.
2806 * main.c (decode_switches): Require non-empty strings for all our
2807 string command-line options. Fixes Debian bug # 164165.
2809 * configure.in: Check for stdarg.h and varargs.h.
2810 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2811 for printing messages.
2812 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2817 A number of patches for OS/2 support from Andreas Buening
2818 <andreas.buening@nexgo.de>:
2820 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2821 disable the SIGCHLD handler.
2822 (reap_children) [OS/2]: Remove special handling of job_rfd.
2823 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2824 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2825 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2826 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2827 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2830 2004-02-21 Paul D. Smith <psmith@gnu.org>
2832 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2833 <mail@kristov.de> reports that if process_begin() fails we don't
2834 handle the error condition correctly in all cases.
2835 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2836 to have a newline on the message.
2838 * job.c (construct_command_argv_internal): Add "test" to UNIX
2839 sh_cmds[]. Fixes Savannah bug # 7606.
2841 2004-02-04 Paul D. Smith <psmith@gnu.org>
2843 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2844 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2845 Hartmut Becker <Hartmut.Becker@hp.com>.
2847 2004-01-21 Paul D. Smith <psmith@gnu.org>
2849 * job.c (load_too_high): Implement an algorithm to control the
2850 "thundering herd" problem when using -l to control job creation
2851 via the load average. The system only recomputes the load once a
2852 second but we can start many jobs in a second. To solve this we
2853 keep track of the number of jobs started in the last second and
2854 apply a weight to try to guess what a correct load would be.
2855 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2856 Also fixes bug #4693.
2857 (reap_children): Decrease the job count for this second.
2858 (start_job_command): Increase the job count for this second.
2860 * read.c (conditional_line): Expand the text after ifn?def before
2861 checking to see if it's a single word. Fixes bug #7257.
2863 2004-01-09 Paul D. Smith <psmith@gnu.org>
2865 * file.c (print_file): Recurse to print all targets in
2866 double-colon rules. Fixes bug #4518, reported (with patch) by
2867 Andrew Chatham <chatham@google.com>.
2869 2004-01-07 Paul D. Smith <psmith@gnu.org>
2871 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2872 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2873 AC_FUNC_SETVBUF_REVERSED.
2875 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2876 (MAKE Variable): Fix Savannah bug #4898.
2878 * job.c (construct_command_argv_internal): Add "!" to the list of
2879 shell escape chars. POSIX sh allows it to appear before a
2880 command, to negate the exit code. Fixes bug #6404.
2882 * implicit.c (pattern_search): When matching an implicit rule,
2883 remember which dependencies have the ignore_mtime flag set.
2884 Original fix provided in Savannah patch #2349, by Benoit
2885 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2887 2003-11-22 Paul D. Smith <psmith@gnu.org>
2889 * README.W32.template (Outputs): Clarification on -j with
2890 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2893 2003-11-02 Paul D. Smith <psmith@gnu.org>
2895 * function.c (func_if): Strip all the trailing whitespace from the
2896 condition, then don't expand it. Fixed bug # 5798.
2898 * expand.c (recursively_expand_for_file): If we're expanding a
2899 variable with no file context, then use the variable's context.
2902 2003-10-21 Paul D. Smith <psmith@gnu.org>
2904 * main.c (log_working_directory): Add newlines to printf()s.
2906 * README.cvs: Add a note to ignore warnings during autoreconf.
2908 * maintMakefile (po_repo): Set a new URL for PO file updates.
2909 (get-config/config.guess get-config/config.sub): Get these files
2910 from the Savannah config project instead of ftp.gnu.org.
2912 2003-10-05 Paul Eggert <eggert@twinsun.com>
2914 * main.c (main): Avoid potential subscript error if environ has
2917 2003-08-22 Paul D. Smith <psmith@gnu.org>
2919 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2920 systems which don't yet implement the C89 standard :-/.
2922 2003-07-18 Paul D. Smith <psmith@gnu.org>
2924 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2925 [WINDOWS32]: Initialize hash.
2927 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2929 * dir.c (read_dirstream): Provide a workaround for broken versions of
2930 the MinGW dirent structure.
2932 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2934 * w32/include/dirent.h: Add __MINGW32__ filter.
2936 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2938 * make.h: Add global declaration of *make_host.
2939 * main.c (print_usage): Remove local declaration of *make_host.
2940 (print_version): Display "This program built for ..." after Copyright
2943 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2945 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2946 execution of "makeinfo --html make.texi".
2948 2003-04-30 Paul D. Smith <psmith@gnu.org>
2950 * build.template: Make some changes to maybe allow this script to
2951 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2953 * README.OS2.template: New file for OS/2 support. Original
2954 contributed by Andreas Buening.
2955 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2958 2003-04-19 Paul D. Smith <psmith@gnu.org>
2960 Fix bug #1405: allow a target to match multiple pattern-specific
2963 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2964 variable.c, where they've always belonged.
2965 * rule.h: Move the prototypes and struct pattern_var as well.
2966 * variable.c (initialize_file_variables): Invoke
2967 lookup_pattern_var() in a loop, until no more matches are found.
2968 If a match is found, create a new variable set for the target's
2969 pattern variables. Then merge the contents of each matching
2970 pattern variable set into the target's pattern variable set.
2971 (lookup_pattern_var): Change this function to be usable
2972 in a loop. It takes a starting position: if NULL, start at the
2973 beginning; if non-NULL, start with the pattern variable after that
2974 position, and return the next matching pattern.
2975 (create_pattern_var): Create a unique instance of
2976 pattern-specific variables for every definition in the makefile.
2977 Don't combine the same pattern together. This allows us to
2978 process the variable handling properly even when the same pattern
2979 is used multiple times.
2980 (parse_variable_definition): New function: break out the parsing
2981 of a variable definition line from try_variable_definition.
2982 (try_variable_definition): Call parse_variable_definition to
2984 (print_variable_data_base): Print out pattern-specific variables.
2985 * variable.h (struct variable): Remember when a variable is
2986 conditional. Also remember its flavor.
2987 (struct pattern_var): Instead of keeping a variable set, we just
2988 keep a single variable for each pattern.
2989 * read.c (record_target_var): Each pattern variable contains only a
2990 single variable, not a set, so create it properly.
2991 * doc/make.texi (Pattern-specific): Document the new behavior.
2993 2003-04-17 Paul D. Smith <psmith@gnu.org>
2995 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2996 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2997 file/directory naming rules for VMS so I can't tell whether this
3000 2003-04-09 Paul D. Smith <psmith@gnu.org>
3002 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3003 DOS-style pathnames: backslash separators and drive specifiers.
3005 2003-03-28 Paul D. Smith <psmith@gnu.org>
3007 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3008 the intermediate flag on all targets. Fixes bug #2515.
3010 2003-03-24 Paul D. Smith <psmith@gnu.org>
3012 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3013 Upgrade to autoconf 2.57 and automake 1.7.3.
3015 * job.c: More OS/2 changes from Andreas Buening.
3017 * file.c (print_file): Fix variable initialization.
3020 * remake.c (notice_finished_file):
3022 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3023 some calls (like readdir()) return NULL in valid situations
3024 without resetting errno. Fixes bug #2846.
3026 2003-02-25 Paul D. Smith <psmith@gnu.org>
3028 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3030 * job.c (_is_unixy_shell) [OS/2]: New function.
3031 Set default shell to /bin/sh.
3032 (reap_children): Close the job_rfd pipe here since we don't use a
3034 (set_child_handler_action_flags): define this to empty on OS/2.
3035 (start_job_command): Close the jobserver pipe and use
3036 child_execute_job() instead of fork/exec.
3037 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3038 rather than exec'ing, then reconfigure stdin/stdout.
3039 (exec_command): Rewrite to use spawn instead of exec. Return the
3042 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3043 in DOS. Handle the TEMP environment variable as in DOS. Don't
3044 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3045 use -j in DOS mode. Use child_execute_job() instead of
3048 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3051 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3052 prototypes that return values.
3054 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3056 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3057 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3059 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3062 2003-02-24 Paul D. Smith <psmith@gnu.org>
3064 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3065 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3066 (child_execute_job) [VMS]: Handle error status properly.
3067 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3069 * function.c (func_shell): Use EINTRLOOP() while reading from the
3070 subshell pipe (Fixes bug #2502).
3071 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3073 * main.c (main): Ditto.
3075 2003-01-30 Paul D. Smith <psmith@gnu.org>
3077 * read.c (eval): eval() was not fully reentrant, because the
3078 collapsed buffer was static. Change it to be an automatic
3079 variable so that eval() can be invoked recursively.
3081 (eval): Apply patch # 1022: fix memory reference error on long
3082 target-specific variable lines.
3083 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3085 * function.c (check_numeric): Combine the is_numeric() function
3086 into this function, since it's only called from one place.
3087 Constify this function. Have it print the incorrect string in the
3088 error message. Fixes bug #2407.
3089 (strip_whitespace): Constify.
3090 (func_if): Constify.
3091 * expand.c (expand_argument): Constify.
3093 2003-01-29 Paul D. Smith <psmith@gnu.org>
3095 Fix bug # 2169, also reported by other people on various systems.
3097 * make.h: Some systems, such as Solaris and PTX, do not fully
3098 implement POSIX-compliant SA_RESTART functionality; important
3099 system calls like stat() and readdir() can still fail with EINTR
3100 even if SA_RESTART has been set on the signal handler. So,
3101 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3102 EINTR for system calls which return -1 or 0 (NULL), respectively,
3104 Also, remove the old atomic_stat()/atomic_readdir() and
3105 HAVE_BROKEN_RESTART handling.
3107 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3109 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3110 * remake.c (touch_file): Ditto.
3112 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3113 * read.c (construct_include_path): Ditto.
3114 * remake.c (name_mtime): Ditto.
3115 * vpath.c (selective_vpath_search): Ditto.
3116 * dir.c (find_directory): Ditto.
3117 (local_stat): Ditto.
3118 (find_directory): Use ENULLLOOP() to wrap opendir().
3119 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3121 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3122 atomic_readdir() handling.
3124 2003-01-22 Paul D. Smith <psmith@gnu.org>
3126 * function.c (func_call): Fix Bug #1744. If we're inside a
3127 recursive invocation of $(call ...), mask any of the outer
3128 invocation's arguments that aren't used by this one, so that this
3129 invocation doesn't "inherit" them accidentally.
3131 2002-12-05 Paul D. Smith <psmith@gnu.org>
3133 * function.c (subst_expand): Valery Khamenia reported a
3134 pathological performance hit when doing substitutions on very
3135 large values with lots of words: turns out we were invoking
3136 strlen() a ridiculous number of times. Instead of having each
3137 call to sindex() call strlen() again, keep track of how much of
3138 the text we've seen and pass the length to sindex().
3140 2002-11-19 Paul D. Smith <psmith@gnu.org>
3142 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3145 2002-11-16 Paul D. Smith <psmith@gnu.org>
3147 * NMakefile.template (OBJS): Add hash.c object file.
3148 * SMakefile.template (srcs): Ditto.
3149 * Makefile.ami (objs): Ditto.
3150 * build_w32.bat: Ditto.
3152 * Makefile.DOS.template: Remove extra dependencies.
3154 2002-10-25 Paul D. Smith <psmith@gnu.org>
3156 * expand.c (install_variable_buffer): New function. Install a new
3157 variable_buffer context and return the previous one.
3158 (restore_variable_buffer): New function. Free the current
3159 variable_buffer context and put a previously saved one back.
3160 * variable.h: Prototypes for {install,restore}_variable_buffer.
3161 * function.c (func_eval): Push a new variable_buffer context
3162 before we eval, then restore the old one when we're done.
3165 * read.c (install_conditionals): New function. Install a new
3166 conditional context and return the previous one.
3167 (restore_conditionals): New function. Free the current
3168 conditional context and put a previously saved one back.
3169 (eval): Use the {install,restore}_conditionals for "include"
3171 (eval_buffer): Use {install,restore}_conditionals to preserve the
3172 present conditional state before we evaluate the buffer.
3175 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3177 (Recursion): Add a variable index entry for CURDIR.
3179 * README.cvs: Update to appropriate versions.
3180 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3181 don't need to copy loadavg.c: automake is smart enough to create
3182 it for me. Still have a bug in automake related to ansi2knr tho.
3184 2002-10-14 Paul D. Smith <psmith@gnu.org>
3186 * remake.c (notice_finished_file): Only touch targets if they have
3187 at least one command (as per POSIX). Resolve Bug #1418.
3189 * *.c: Convert to using ANSI C-style function definitions.
3190 * Makefile.am: Enable the ansi2knr feature of automake.
3191 * configure.in: ditto.
3193 2002-10-13 Paul D. Smith <psmith@gnu.org>
3195 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3196 for automatic variable values like $^, etc. In the case of very
3197 large lists of prerequisites this causes problems. Instead reuse
3198 a static buffer (resizeable) for each variable.
3200 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3201 target-specific variable definitions. Check for it and set an
3203 (record_target_var): Set the export field to v_export if the
3204 "exported" flag is set.
3205 * doc/make.texi (Target-specific): Document the ability to use
3208 * doc/make.texi: Change the name of the section on automatic
3209 variables from "Automatic" to "Automatic Variables". Added text
3210 clarifying the scope of automatic variables.
3212 2002-10-04 Paul D. Smith <psmith@gnu.org>
3214 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3216 (record_files): Ditto.
3218 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3219 the search for the '=' to only within the enclosing parens.
3221 2002-10-03 Paul D. Smith <psmith@gnu.org>
3223 Version 3.80 released.
3225 * dir.c: Change hash functions to use K&R function definition style.
3226 * function.c: Ditto.
3228 * variable.c: Ditto.
3230 Update to automake 1.7.
3232 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3233 (pdf): Remove this target as automake now provides one.
3235 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3237 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3239 * makefile.com: Updates for GNU make 3.80.
3240 * makefile.vms: Ditto.
3242 2002-09-23 Paul D. Smith <psmith@gnu.org>
3244 * read.c (enum make_word_type): Remove w_comment.
3245 (get_next_mword): Don't treat comment characters as special; where
3246 this function is used we will never see a comment (it's stripped
3247 before we get here) and treating comments specially means that
3248 targets like "foo\#bar" aren't handled properly.
3250 2002-09-18 Paul D. Smith <psmith@gnu.org>
3252 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3254 * read.c (eval): Expansion of arguments to export/unexport was
3255 ignoring all arguments after the first one. Change the algorithm
3256 to expand the whole line once, then parse the results.
3258 2002-09-17 Paul D. Smith <psmith@gnu.org>
3260 Fix Bug #940 (plus another bug I found while looking at this):
3262 * read.c (record_target_var): enter_file() will add a new entry if
3263 it's a double-colon target: we don't want to do that in this
3264 situation. Invoke lookup_file() and only enter_file() if it does
3265 not already exist. If the file we get back is a double-colon then
3266 add this variable to the "root" double-colon target.
3268 * variable.c (initialize_file_variables): If this file is a
3269 double-colon target but is not the "root" target, then initialize
3270 the root and make the root's variable list the parent of our
3273 2002-09-13 Paul D. Smith <psmith@gnu.org>
3275 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3277 * hash.c (round_up_2): Get rid of a warning.
3279 2002-09-12 Paul D. Smith <psmith@gnu.org>
3281 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3282 so it doesn't complain about getloadavg.c.
3284 * commands.c (set_file_variables): Make sure we always alloca() at
3285 least 1 character for the value of $? (for '\0').
3287 2002-09-11 Paul D. Smith <psmith@gnu.org>
3289 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3290 macro to use RESULT instead of the incorrect _RESULT_.
3292 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3293 and atomic_readdir(). We need to #include dirent.h to get this to
3295 * misc.c (atomic_readdir): Fix typos.
3297 2002-09-10 Paul D. Smith <psmith@gnu.org>
3299 * read.c (eval): Expand variable lists given to export and
3300 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3301 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3303 * doc/make.texi (Variables/Recursion): Document this.
3304 (Conditional Syntax): And here.
3306 2002-09-09 Paul D. Smith <psmith@gnu.org>
3308 * configure.in: Check for memmove().
3310 2002-09-07 Paul D. Smith <psmith@gnu.org>
3312 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3313 Michael Sterrett <msterret@coat.com> reports that while it has
3314 SA_RESTART, it does not work properly.
3316 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3317 that invokes stat() and loops to do it again if it returns EINTR.
3318 (atomic_readdir): Ditto, with readdir().
3320 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3321 and readdir() to atomic_stat() and atomic_readdir().
3323 2002-09-04 Paul D. Smith <psmith@gnu.org>
3325 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3326 reports that GNU make sometimes doesn't recognize that targets can
3327 be made, when directories can be created as prerequisites. He
3328 reports that changing the order of predicates in the DEP->changed
3329 flag test so that lookup_file() is always performed, solves this
3332 2002-08-08 Paul D. Smith <psmith@gnu.org>
3334 * configure.in: Require a newer version of gettext.
3336 * misc.c (perror_with_name): Translate the format string (for
3337 right-to-left language support).
3338 (pfatal_with_name): Ditto.
3340 * main.c: Create a static array of strings to store the usage
3341 text. This is done to facilitate translations.
3342 (struct command_switch): Remove argdesc and description fields.
3343 (switches): Remove values for obsolete fields.
3344 (print_usage): Print each element of the usage array.
3346 * hash.c: Change function definitions to be K&R style.
3348 2002-08-02 Paul D. Smith <psmith@gnu.org>
3350 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3351 this one because it's too hard to get right. We'll look at it for
3353 * main.c (main): Don't create the .TARGETS variable.
3354 * variable.c (handle_special_var): Don't handle .TARGETS.
3356 2002-08-01 Paul D. Smith <psmith@gnu.org>
3358 * main.c (switches): Add a new option, -B (--always-make). If
3359 specified, make will rebuild all targets that it encounters even
3360 if they don't appear to be out of date.
3361 (always_make_flag): New flag.
3362 * make.h: Extern always_make_flag.
3363 * remake.c (update_file_1): Check always_make_flag; if it's set we
3364 will always rebuild any target we can, even if none of its
3365 prerequisites are newer.
3368 * doc/make.texi (Shell Function): Make it clear that make
3369 variables marked as "export" are not passed to instances of the
3372 Add new introspection variable .VARIABLES and .TARGETS.
3374 * variable.c (handle_special_var): New function. If the variable
3375 reference passed in is "special" (.VARIABLES or .TARGETS),
3376 calculate the new value if necessary. .VARIABLES is handled here:
3377 walk through the hash of defined variables and construct a value
3378 which is a list of the names. .TARGETS is handled by
3379 build_target_list().
3380 (lookup_variable): Invoke handle_special_var().
3381 * file.c (build_target_list): Walk through the hask of known files
3382 and construct a list of the names of all the ones marked as
3384 * main.c (main): Initialize them to empty (and as simple variables).
3385 * doc/make.texi (Special Variables): Document them.
3386 * NEWS: Mention them.
3388 * variable.h (struct variable): Add a new flag "exportable" which
3389 is true if the variable name is valid for export.
3390 * variable.c (define_variable_in_set): Set "exportable" when a new
3391 variable is defined.
3392 (target_environment): Use the "exportable" flag instead of
3393 re-checking the name here... an efficiency improvement.
3395 2002-07-31 Paul D. Smith <psmith@gnu.org>
3397 * config.h-vms.template: Updates to build on VMS. Thanks to
3398 Brian_Benning@aksteel.com for helping verify the build.
3399 * makefile.com: Build the new hash.c file.
3400 * hash.h: Use strcpmi(), not stricmp(), in the
3401 HAVE_CASE_INSENSITIVE_FS case.
3403 2002-07-30 Paul D. Smith <psmith@gnu.org>
3405 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3406 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3407 Reported by <Brian_Benning@aksteel.com>.
3409 2002-07-10 Paul D. Smith <psmith@gnu.org>
3411 * variable.c (pop_variable_scope): Remove variable made unused by
3412 new hash infrastructure.
3413 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3414 comparisons as well as name comparisons.
3415 * variable.h: Add a prototype for new hash_init_function_table().
3416 * file.c (lookup_file): Remove variables made unused by new hash
3418 * dir.c (directory_contents_hash_2): Missing return of hash value.
3419 (dir_contents_file_exists_p): Remove variables made unused by new
3420 hash infrastructure.
3423 Installed Greg McGary's integration of the hash functions from the
3424 GNU id-utils package:
3426 2002-07-10 Greg McGary <greg@mcgary.org>
3428 * scripts/functions/filter-out: Add literals to to the
3429 pattern space in order to add complexity, and trigger
3430 use of an internal hash table. Fix documentation strings.
3431 * scripts/targets/INTERMEDIATE: Reverse order of files
3432 passed to expected `rm' command.
3434 2002-07-10 Greg McGary <greg@mcgary.org>

3511 variable_hash_cmp): New functions.

3526 2002-07-10 Paul D. Smith <psmith@gnu.org>
3528 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3529 prerequisite list. A real SysV make will expand the entire
3530 prerequisites list _twice_: we don't do that as it's a big
3531 backward-compatibility problem. We only replace those specific
3534 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3535 references left in the list of prerequisites. Check for .POSIX as
3536 we record targets, so we can disable non-POSIX behavior while
3537 reading makefiles as well as running them.
3538 (eval): Check the prerequisite list to see if we have anything
3539 that looks like a SysV prerequisite variable reference.
3541 2002-07-09 Paul D. Smith <psmith@gnu.org>
3543 * doc/make.texi (Prerequisite Types): Add a new section describing
3544 order-only prerequisites.
3546 * read.c (uniquize_deps): If we have the same file as both a
3547 normal and order-only prereq, get rid of the order-only prereq,
3548 since the normal one supersedes it.
3550 2002-07-08 Paul D. Smith <psmith@gnu.org>
3552 * AUTHORS: Added Greg McGary to the AUTHORS file.
3553 * NEWS: Blurbed order-only prerequisites.
3554 * file.c (print_file): Show order-only deps properly when printing
3557 * maintMakefile: Add "update" targets for wget'ing the latest
3558 versions of various external files. Taken from Makefile.maint in
3561 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3562 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3564 2002-07-07 Paul D. Smith <psmith@gnu.org>
3566 * po/*.po: Remove. We'll use wget to retrieve them at release
3569 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3570 rather than a shell you get an exception. Make sure we look up
3571 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3573 * remake.c (notice_finished_file): Fix handling of -t flag.
3574 Patch provided by Henning Makholm <henning@makholm.net>.
3576 * implicit.c (pattern_search): Some systems apparently run short
3577 of stack space, and using alloca() in this function caused an
3578 overrun. I modified it to use xmalloc() on the two variables
3579 which seemed like they might get large. Fixes Bug #476.
3581 * main.c (print_version): Update copyright notice to conform with
3583 (print_usage): Update help output.
3585 * function.c (func_eval): Create a new make function, $(eval
3586 ...). Expand the arguments, put them into a buffer, then invoke
3587 eval_buffer() on the resulting string.
3588 (func_quote): Create a new function, $(quote VARNAME). Inserts
3589 the value of the variable VARNAME without expanding it any
3592 * read.c (struct ebuffer): Change the linebuffer structure to an
3593 "eval buffer", which can be either a file or a buffer.
3594 (eval_makefile): Move the code in the old read_makefile() which
3595 located a makefile into here: create a struct ebuffer with that
3596 information. Have it invoke the new function eval() with that
3598 (eval_buffer): Create a new function that creates a struct ebuffer
3599 that holds a string buffer instead of a file. Have it invoke
3600 eval() with that ebuffer.
3601 (eval): New function that contains the guts of the old
3602 read_makefile() function: this function parses makefiles. Obtains
3603 data to parse from the provided ebuffer. Some modifications to
3604 make the flow of the function cleaner and clearer. Still could
3605 use some work here...
3606 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3607 contents of the define/endef variable from the ebuffer.
3608 (readstring): Read the next line from a string-style ebuffer.
3609 (readline): Read the next line from an ebuffer. If it's a string
3610 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3613 * dep.h (eval_buffer): Prototype eval_buffer();
3615 * variable.c (do_variable_definition): Make sure that all
3616 non-target-specific variables are registered in the global set.
3617 If we're invoked from an $(eval ...) we might be inside a $(call
3618 ...) or other function which has pushed a variable scope; we still
3619 want to define our variables from evaluated makefile code in the
3622 2002-07-03 Greg McGary <greg@mcgary.org>
3624 * dep.h (struct dep) [ignore_mtime]: New member.
3625 [changed]: convert to a bitfield.
3626 * implicit.c (pattern_search): Zero ignore_mtime.
3627 * main.c (main, handle_non_switch_argument): Likewise.
3628 * rule.c (convert_suffix_rule): Likewise.
3629 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3630 (read_makefile): Parse '|' in prerequisite list.
3631 (uniquize_deps): Consider ignore_mtime when comparing deps.
3632 * remake.c (update_file_1, check_dep): Don't force remake for
3633 dependencies that have d->ignore_mtime.
3634 * commands.c (FILE_LIST_SEPARATOR): New constant.
3635 (set_file_variables): Don't include a
3636 prerequisite in $+, $^ or $? if d->ignore_mtime.
3639 2002-06-18 Paul D. Smith <psmith@gnu.org>
3641 * make.texinfo: Updates for next revision. New date/rev/etc.
3642 Recreate all Info menus. Change license on the manual to the GNU
3643 Free Documentation License. A number of typos.
3644 (Variables Simplify): Don't use "-" before it's defined.
3645 (Automatic Prerequisites): Rewrite the target example to work
3646 properly if the compile fails. Remove incorrect comments about
3647 how "set -e" behaves.
3648 (Text Functions): Move the "word", "wordlist", "words", and
3649 "firstword" functions here, from "File Name Functions".
3650 * make-stds.texi: Update from latest GNU version.
3651 * fdl.texi: (created) Import the latest GNU version.
3653 2002-06-06 Paul D. Smith <psmith@gnu.org>
3655 * variable.c (do_variable_definition): New function: extract the
3656 part of try_variable_definition() that actually sets the value
3657 into a separate function.
3658 (try_variable_definition): Call do_variable_definition() after
3659 parsing the variable definition string.
3660 (define_variable_in_set): Make the name argument const.
3662 * variable.h (enum variable_flavor): Make public.
3663 (do_variable_definition): Create prototype.
3665 * read.c (read_all_makefiles): Create a new built-in variable,
3667 (read_makefile): Add each makefile read in to this variable value.
3669 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3671 * Makefile.DOS.template: Tweak according to changes in the
3672 distribution. Add back the dependencies of *.o files.
3674 * configh.dos.template: Synchronize with config.h.in.
3676 2002-05-09 Paul D. Smith <psmith@gnu.org>
3678 * file.c (file_timestamp_now): Use K&R function declaration.
3680 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3681 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3682 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3683 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3684 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3685 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3686 nlist.n_name is a pointer rather than an array.
3688 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3689 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3690 * configure.in: Use it instead of the old version.
3692 * main.c (main): Prefer setvbuf() to setlinebuf().
3694 2002-05-08 Paul D. Smith <psmith@gnu.org>
3696 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3697 (loadavg_LDADD): Ditto.
3699 2002-04-29 Paul D. Smith <psmith@gnu.org>
3701 * expand.c (recursively_expand_for_file): Rename
3702 recursively_expand() to recursively_expand_for_file() and provide
3703 an extra argument, struct file. If the argument is provided, set
3704 the variable scope to that of the file before expanding.
3705 * variable.h (recursively_expand): Make this a macro that invokes
3706 recursively_expand_for_file() with a NULL file pointer.
3707 * variable.c (target_environment): Call the renamed function and
3708 provide the current file context.
3709 Fixes Debian bug #144306.
3711 2002-04-28 Paul D. Smith <psmith@gnu.org>
3713 Allow $(call ...) user-defined variables to be self-referencing
3714 without throwing an error. Allows implementation of transitive
3715 closures, among other possibly useful things.
3716 Requested by: Philip Guenther <guenther@sendmail.com>
3718 * variable.h (struct variable): Add a new field: exp_count, and
3719 new macros to hold its size and maximum value.
3720 (warn_undefined): Make this a macro.
3721 * variable.c (define_variable_in_set): Initialize it.
3722 * expand.c (recursively_expand): If we detect recursive expansion
3723 of a variable, check the exp_count field. If it's greater than 0
3724 allow the recursion and decrement the count.
3725 (warn_undefined): Remove this (now a macro in variable.h).
3726 * function.c (func_call): Before we expand the user-defined
3727 function, modify its exp_count field to contain the maximum
3728 number of recursive calls we'll allow. After the call, reset it
3731 2002-04-21 Paul D. Smith <psmith@gnu.org>
3733 Modified to use latest autoconf (2.53), automake (1.6.1), and
3734 gettext (0.11.1). We're using gettext's new "external" support,
3735 to avoid including libintl source with GNU make.
3737 * README.cvs: New file. Explain how to build GNU make from CVS.
3739 * configure.in: Modify checking for the system glob library.
3740 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3741 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3742 etc. will manage it correctly). Set an automake conditional
3743 USE_LOCAL_GLOB to decide whether to compile the glob library.
3745 * getloadavg.c (main): Include make.h in the "TEST" program to
3748 * Makefile.am: Remove special rules for loadavg. Replace them
3749 with Automake capabilities for building extra programs.
3751 * signame.c: This file does nothing if the system provide
3752 strsignal(). If not, it implements strsignal(). If the system
3753 doesn't define sys_siglist, then we make our own; otherwise we use
3755 * signame.h: Removed.
3757 * main.c (main): No need to invoke signame_init(). Update copyright.
3759 * ABOUT-NLS: Removed.
3760 * gettext.c: Removed.
3761 * gettext.h: Get a simplified copy from the gettext package.
3763 * i18n/*.po: Moved to po/.
3766 * config/*: Created. Contains package configuration helper files.
3767 * config.guess, config.sub: Moved to config directory.
3769 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3770 Rework to use new-style autoconf features. Use the "external"
3771 mode for gettext. Make the build.sh config file conditional on
3772 whether build.sh.in exists, to avoid autoconf errors.
3773 * acinclude.m4: Removed almost all macros as being obsolete.
3774 Rewrote remaining macros to use AC_DEFINE.
3775 * acconfig.h: Removed.
3777 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3778 conditional to handle customs support. Remove special handling
3781 2002-04-20 Paul D. Smith <psmith@gnu.org>
3783 * function.c (func_call): Don't mark the argument variables $1,
3784 etc. as recursive. They've already been fully expanded so
3785 there's no need to do it again, and doing so strips escaped $'s.
3786 Reported by Sebastian Glita <glseba@yahoo.com>.
3788 * remake.c (notice_finished_file): Walk through double-colon
3789 entries via the prev field, not the next field!
3790 Reported by Greg McGary <greg@mcgary.org>.
3792 * main.c (main): If the user specifies -q and asks for a specific
3793 target which is a makefile, we got an assert. In that case it
3794 turns out we should continue normally instead.
3796 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3798 * i18n/he.po: Installed a new translation.
3800 2002-01-07 Paul D. Smith <psmith@gnu.org>
3802 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3804 2001-12-04 Paul D. Smith <psmith@gnu.org>
3806 * i18n/ja.po: Installed an updated translation.
3808 2001-09-06 Paul Eggert <eggert@twinsun.com>
3810 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3811 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3813 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3815 (main): Get rid of any avoidable limit on stack size.
3817 2001-09-04 Paul D. Smith <psmith@gnu.org>
3819 * i18n/da.po: Installed an updated translation.
3821 2001-08-03 Paul D. Smith <psmith@gnu.org>
3823 * i18n/fr.po: Installed an updated translation.
3824 Resolves Debian bug #106720.
3826 2001-06-13 Paul D. Smith <psmith@gnu.org>
3828 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3831 2001-06-11 Paul D. Smith <psmith@gnu.org>
3833 * i18n/ko.po: Installed a new translation.
3835 2001-05-06 Paul D. Smith <psmith@gnu.org>
3837 Modify the EINTR handling.
3839 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3840 the way in which we manage the file descriptor/signal handler race
3841 trap to be more efficient.
3843 2001-05-06 Paul Eggert <eggert@twinsun.com>
3845 Restart almost all system calls that are interrupted, instead
3846 of worrying about EINTR. The lone exception is the read() for
3849 * configure.in (HAVE_SA_RESTART): New macro.
3850 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3851 * main.c (main): Use SA_RESTART instead of the old,
3852 nonstandard SA_INTERRUPT.
3854 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3855 * main.c (bsd_signal): New function or macro,
3856 if the implementation doesn't supply it.
3857 (The bsd_signal function will be in POSIX 1003.1-200x.)
3858 (HANDLESIG): Remove.
3859 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3861 * make.h (EINTR_SET): Remove.
3862 (SA_RESTART): New macro.
3864 * arscan.c (ar_member_touch): Don't worry about EINTR.
3865 * function.c (func_shell): Likewise.
3866 * job.c (reap_children, free_child, new_job): Likewise.
3867 * main.c (main): Likewise.
3868 * remake.c (touch_file, name_mtime): Likewise.
3870 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3871 if fstat failed with errno!=EINTR, the error was ignored.
3873 * job.c (set_child_handler_action_flags): New function.
3874 (new_job): Use it to temporarily clear the SIGCHLD action flags
3875 while reading the token.
3877 2001-05-02 Paul D. Smith <psmith@gnu.org>
3879 * job.c (start_job_command): Don't add define/endef per-line flags
3880 to the top-level flags setting.
3882 2001-04-03 Paul D. Smith <psmith@gnu.org>
3884 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3885 bit on error, so check for odd return values, not non-0 return
3887 (VMS_get_member_info): Calculate the timezone differences correctly.
3888 Reported by John Fowler <jfowler@nyx.net>.
3891 2001-03-14 Paul D. Smith <psmith@gnu.org>
3893 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3894 value before invoking define_variable().
3895 Reported by John Fowler <jfowler@nyx.net>.
3897 2001-02-07 Paul D. Smith <psmith@gnu.org>
3899 * read.c (record_target_var): If we reset the variable due to a
3900 command-line variable setting overriding it, turn off the "append"
3903 2001-01-17 Paul D. Smith <psmith@gnu.org>
3905 * variable.c (lookup_variable) [VMS]: When getting values from the
3906 environment, allocate enough space for the _value_ plus escapes,
3907 not enough space for the name plus escapes :-/.
3908 Reported by John Fowler <jfowler@nyx.net>.
3910 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3911 warnings that make generates, so it doesn't look like an error.
3912 Reported by Karl Berry <karl@gnu.org>.
3915 Fix for PR/2020: Rework appended target-specific variables. I'm
3916 fairly confident this algorithm is finally correct.
3918 * expand.c (allocated_variable_append): Rewrite. Instead of
3919 expanding each appended variable then adding all the expanded
3920 strings together, we append all the unexpanded values going up
3921 through the variable set contexts, then expand the final result.
3922 This behaves just like non-target-specific appended variable
3923 values, while the old way didn't in various corner cases.
3924 (variable_append): New function: recursively append the unexpanded
3925 value of a variable, walking from the outermost variable scope to
3927 * variable.c (lookup_variable): Remove the code that looked up the
3928 variable set list if the found variable was "append". We don't
3930 (lookup_variable_in_set): Make this non-static so we can use it
3932 (try_variable_definition): Use lookup_variable_in_set() rather
3933 than faking out current_variable_set_list by hand (cleanup).
3934 * variable.h: Add a prototype for the now non-static
3935 lookup_variable_in_set().
3937 2000-11-17 Paul D. Smith <psmith@gnu.org>
3939 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3940 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3941 before throwing a fit.
3943 2000-11-17 Paul D. Smith <psmith@gnu.org>
3945 * read.c (readline): CRLF calculations had a hole, if you hit the
3946 buffer grow scenario just right. Reworked the algorithm to avoid
3947 the need for len or lastlen at all. Problem description with
3948 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3950 2000-10-24 Paul D. Smith <psmith@gnu.org>
3952 * gettext.c (SWAP): Declare this with the prototype, otherwise
3953 some systems don't work (non-32-bit? Reported for Cray T3E).
3954 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3956 2000-10-05 Paul D. Smith <psmith@gnu.org>
3958 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3959 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3961 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3963 2000-09-22 Paul D. Smith <psmith@gnu.org>
3965 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3966 parts of the real gettext.h here, and we expect to really include
3967 the real gettext.h later. If we keep this #define, it's ignored.
3969 2000-09-21 Paul D. Smith <psmith@gnu.org>
3971 * main.c (log_working_directory): Rework the text to use complete
3972 sentences, to make life simpler for the translators.
3974 2000-08-29 Paul D. Smith <psmith@gnu.org>
3976 * file.c (remove_intermediates): Print a debug message before we
3977 remove intermediate files, so the user (if she uses -d) knows
3980 2000-08-21 Paul D. Smith <psmith@gnu.org>
3982 * variable.c (try_variable_definition): Change how we handle
3983 target-specific append variable defns: instead of just setting the
3984 value, expand it as an append _but_ only within the current
3985 target's context. Otherwise we lose all but the last value if the
3986 variable is appended more than once within the current target
3987 context. Fixes PR/1831.
3989 2000-08-16 Paul D. Smith <psmith@gnu.org>
3991 * function.c (func_shell): Nul-terminate the buffer before
3992 printing an exec error message (just in case it's not!).
3993 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3995 2000-07-25 Paul D. Smith <psmith@gnu.org>
3997 * job.c (construct_command_argv_internal): Add "~" to the list of
3998 sh_chars[] which disallow optimizing out the shell call.
4000 2000-07-23 Paul Eggert <eggert@twinsun.com>
4002 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4003 supersedes --disable-nsec-timestamps.
4004 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4005 * README: Remove --disable-nsec-timestamps.
4007 * filedef.h (struct file.low_resolution_time): New member.
4008 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4009 * remake.c (update_file_1):
4010 Avoid spurious rebuilds due to low resolution time stamps,
4011 generalizing the earlier code that applied only to archive members.
4012 (f_mtime): Archive members always have low resolution time stamps.
4014 * configure.in: Remove --disable-nsec-timestamps, as this has
4015 been superseded by .LOW_RESOLUTION_TIME.
4017 2000-07-23 Paul Eggert <eggert@twinsun.com>
4019 * configure.in (enable_nsec_timestamps): Renamed from
4020 make_cv_nsec_timestamps, since enable/disable options
4021 shouldn't be cached.
4023 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4024 and Paul Eggert <eggert@twinsun.com>
4026 * file.c (file_timestamp_now):
4027 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4028 so that clock_gettime is not linked unless needed.
4030 * filedef.h (FILE_TIMESTAMP_HI_RES):
4031 Remove definition; "configure" now does this.
4033 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4034 to before high resolution file timestamp check,
4035 since that check now uses uintmax_t.
4036 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4037 high resolution file timestamps.
4038 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4039 so that we don't link in clock_gettime unnecessarily.
4041 2000-07-17 Paul D. Smith <psmith@gnu.org>
4043 * i18n/ja.po: New version of the translation file.
4045 2000-07-07 Paul D. Smith <psmith@gnu.org>
4047 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4048 the offset calculation.
4049 (name_mtime): Replace EINTR test with EINTR_SET macro.
4051 2000-07-07 Paul Eggert <eggert@twinsun.com>
4055 * remake.c (update_file_1):
4056 Avoid spurious rebuilds of archive members due to their
4057 timestamp resolution being only one second.
4058 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4059 the clock's resolution being lower than file timestamps'.
4060 When warning about future timestamps, report only the discrepancy,
4061 not the absolute value of the timestamp and the current time.
4063 * file.c (file_timestamp_now): New arg RESOLUTION.
4064 * filedef.h (file_timestamp_now): Likewise.
4065 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4067 2000-07-05 Paul D. Smith <psmith@gnu.org>
4069 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4070 to listp. Fixes PR/1793.
4072 2000-06-26 Paul Eggert <eggert@twinsun.com>
4074 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4076 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4078 * remake.c (f_mtime): Remove unused var memtime.
4080 2000-06-25 Martin Buchholz <martin@xemacs.org>
4082 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4083 Ran spell-check on make.texinfo.
4085 2000-06-23 Paul D. Smith <psmith@gnu.org>
4087 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4088 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4089 * make.h: Define these macros.
4091 * Version 3.79.1 released.
4093 * configure.in: Add a new option, --disable-nsec-timestamps, to
4094 avoid using sub-second timestamps on systems that support it. It
4095 can lead to problems, e.g. if your makefile relies on "cp -p".
4096 * README.template: Document the issue with "cp -p".
4098 * config.guess, config.sub: Updated.
