477 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
479 * configh.dos.template: Remove unconditional definition of
480 SYS_SIGLIST_DECLARED.
481 Include <sys/version.h> because ports of GCC 4.3.0 and later no
482 longer include it, so macros like __DJGPP_MINOR__ are no longer
483 defined automatically.
485 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
486 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
487 instead of using the hardcoded ones.
488 (SUBDIRS): doc subdir added.
489 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
490 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
491 create html formated docs. texi2html may not be ported to DOS.
492 (make.info, make.dvi, make.ps, make.html): Make targets depend on
494 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change

497 (make_1.html): Removed.
498 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

502 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
503 (tags-recursive): Allow for more than one subdir in the build
505 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New

523 * implicit.c (pattern_search): Terminate early if we haven't
524 found any rules to try (performance improvement).
526 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
528 * implicit.c (pattern_search): Merge three parallel arrays,
529 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
530 of struct TRYRULE. In the old version the latter two arrays
531 had insufficient length.
533 2009-09-24 Paul Smith <psmith@gnu.org>
535 * implicit.c (pattern_search): Add back support for order-only
536 prerequisites for secondary expansion implicit rules, that were
537 accidentally dropped. If we find a "|", enable order-only mode
538 and set IGNORE_MTIME on all deps that are seen afterward.
539 (pattern_search): Fix memory leaks: for intermediate files where
540 we've already set the file variable and pattern variable sets, be
541 sure to either save or free them as appropriate.
543 2009-09-23 Paul Smith <psmith@gnu.org>
545 Rework the way secondary expansion is stored, for efficiency.
546 This changes secondary expansion so that ONLY WHEN we know we have
547 a possibility of needing secondary expansion, do we defer the
548 secondary expansion. This means more parsing the deps but we use
549 a lot less memory (due to the strcache). Also, this fixes
552 * read.c (eval): Don't parse the dep string here anymore.
553 (record_files): Take the dep argument as an unparsed string. If
554 secondary expansion is enabled AND the prereq string has a '$' in
555 it, then set NEED_2ND_EXPANSION and keep the entire string.
556 Otherwise, parse the dep string here to construct the dep list
557 with the names in the strcache.
559 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
560 duplicate the name string (others are in the strcache).
562 * implicit.c: Remove struct idep and free_idep_chain(): unused.
563 (struct patdeps): New structure to store prereq information.
564 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
565 which prerequisites need expansion, and expand only those.
567 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
568 and enter_prereqs(). split_prereqs() takes a fully-expanded string
569 and splits it into a DEP list, handling order-only prereqs.
570 (enter_prereqs): This function enters a list of DEPs into the file
571 database. If there's a stem defined, expand any pattern chars.
572 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
573 set. Use the above functions.
574 (snap_deps): Only perform second expansion on prereqs that need it,
575 as defined by the NEED_2ND_EXPANSION flag.
576 (print_prereqs): New function to print the prereqs
577 (print_file): Call print_prereqs() rather than print inline.
579 * hash.h (STRING_COMPARE): Take advantage of strcache() by
581 (STRING_N_COMPARE): Ditto.
582 (ISTRING_COMPARE): Ditto.
584 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
585 (parse_file_seq): Return void*
586 * read.c (parse_file_seq): Return void*.
587 (eval): Invoke macroized version of parse_file_seq()
588 * default.c (set_default_suffixes): Ditto.
589 * file.c (split_prereqs): Ditto.
590 * function.c (string_glob): Ditto.
591 * main.c (main): Ditto.
592 * rule.c (install_pattern_rule): Ditto.
594 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
596 2009-09-16 Paul Smith <psmith@gnu.org>
598 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
600 * dep.h: Create alloc_dep() / free_dep() macros.
602 * implicit.c (pattern_search): Take advantage of the new
603 parse_file_seq() to add the directory prefix to each prereq.
605 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
606 all. Avoid reversing chains. Support adding prefixes.
607 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
608 cached/non-cached results.
609 (eval): Remove multi_glob() & invoke new parse_file_seq().
610 * rule.c (install_pattern_rule): Ditto.
611 * main.c (main): Ditto.
612 * implicit.c (pattern_search): Ditto.
613 * function.c (string_glob): Ditto.
614 * file.c (parse_prereqs): Ditto.
615 * default.c (set_default_suffixes): Ditto.
617 * variable.c (parse_variable_definition): Don't run off the end of
618 the string if it ends in whitespace (found with valgrind).
620 * commands.c (set_file_variables): Keep space for all targets in
621 $? if -B is given (found with valgrind).
623 2009-09-15 Paul Smith <psmith@gnu.org>
625 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
626 (xcalloc): Add new function.
627 * make.h: New declarations.
629 * ar.c (ar_glob_match): New calling method for concat().
630 * main.c (main): Ditto.
631 (decode_env_switches): Ditto.
632 * read.c (eval_makefile): Ditto.
633 (tilde_expand): Ditto.
634 (parse_file_seq): Ditto.
635 * variable.c (target_environment): Ditto.
636 (sync_Path_environment): Ditto.
638 * ar.c (ar_glob_match): Use xcalloc().
639 * dir.c (file_impossible): Ditto.
640 * file.c (enter_file): Ditto.
641 * job.c (new_job): Ditto.
642 * read.c (parse_file_seq): Ditto.
643 * vmsfunctions.c (opendir): Ditto.
645 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
647 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
648 inside the loop that looks up environment for PATH.
650 2009-08-31 Eli Zaretskii <eliz@gnu.org>
652 * function.c (windows32_openpipe): Update envp after calling
653 sync_Path_environment.
655 2009-08-02 Paul Smith <psmith@gnu.org>
657 * remake.c (notice_finished_file): Ensure file->cmds is not null
658 before looping through them. Fixes Savannah bug #21824.
660 * doc/make.texi (Wildcard Examples): Clarify when objects is
661 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
662 (Include): Clarify the behavior of -include.
663 Fixes Savannah bug #18963.
665 2009-08-01 Paul Smith <psmith@gnu.org>
667 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
668 etc. come on the command line. Fixes Savannah bug #27093.
670 * expand.c (expand_argument): If the argument is large enough use
671 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
673 * variable.c (do_variable_definition): Avoid using alloca() to
674 hold values, which can be large. Fixes Savannah bug #23960.
676 * job.c (new_job): Use memmove() instead of strcpy() since both
677 pointers are in the same memory block. Fixes Savannah bug #27148.
678 Patch by Petr Machata.
680 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
682 * job.c (construct_command_argv_internal): Add "ulimit" and
683 "unset" to the sh_cmds for Unixy shells.
685 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
687 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
688 that set make_cv_sys_gnu_glob, so they are also correctly set
689 when the cache has been populated before.
691 2009-07-04 Eli Zaretskii <eliz@gnu.org>
693 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
694 exist, as realpath(3) does where it's supported.
696 2006-07-04 Eli Zaretskii <eliz@gnu.org>
698 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
699 (abspath): Support systems that define HAVE_DOS_PATHS (have
700 drive letters in their file names). Use IS_PATHSEP instead of a
701 literal '/' comparison. Fixes Savannah bug #26886.
703 2009-06-14 Paul Smith <psmith@gnu.org>
705 * remake.c (update_file_1): Remember the original file we marked
706 as updating, so we can clear that flag again. If we find a target
707 via vpath, FILE might change.
708 (check_dep): Ditto. Fixes Savannah bug #13529.
709 Patch by Reid Madsen <reid.madsen@tek.com>.
711 2009-06-13 Paul Smith <psmith@gnu.org>
713 * doc/make.texi (MAKEFILES Variable): Be explicit that files
714 included by MAKEFILES cannot give default goals.
715 * read.c (eval): If set_default is not set, pass the no-default-goal
716 value when we read included makefiles. Fixes Savannah bug #13401.
718 * ar.c (ar_name): Ensure that targets with empty parens aren't
719 considered archive member references: archive members must have a
720 non-empty "member" string. Fixes Savannah bug #18435.
722 * function.c (string_glob): Rely on multi_glob() to determine
723 whether files exist or not. Remove call to file_exists_p() which
724 is not always correct. Fixes Savannah bug #21231.
725 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
726 then only files that really exist will be returned.
727 * dep.h: Add new argument to multi_glob().
728 * rule.c (install_pattern_rule): Ditto.
729 * read.c (eval): Ditto.
730 * main.c (main): Ditto.
731 * implicit.c (pattern_search): Ditto.
732 * file.c (parse_prereqs): Ditto.
733 * default.c (set_default_suffixes): Ditto.
735 2009-06-09 Paul Smith <psmith@gnu.org>
737 * commands.c (set_file_variables): If always_make_flag is set,
738 always add the prereq to $?. Fixes Savannah bug #17825.
740 * remake.c (update_file_1): When rebuilding deps of FILE, also try
741 to rebuild the deps of all the also_make targets for that file.
742 Fixes Savannah bug #19108.
744 * implicit.c (pattern_search): Undo test for is_target, added by
745 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
746 Rule Search Algorithm". Fixes Savannah bug #17752.
748 * main.c (clean_jobserver): Clear the jobserver_fds options and
749 set job_slots to the default when we clean up.
750 (define_makeflags): Return the new MAKEFLAGS value.
751 (main): Reset MAKEFLAGS in the environment when we re-exec.
752 Fixes Savannah bug #18124.
754 2009-06-08 Paul Smith <psmith@gnu.org>
756 * read.c (eval): Collapse continuations post-semicolon on target-
757 specific variables. Fixes Savannah bug #17521.
759 2009-06-07 Paul Smith <psmith@gnu.org>
761 * job.c (reap_children): For older systems without waitpid() (are
762 there any of these left?) run wait(2) inside EINTRLOOP to handle
763 EINTR errors. Fixes Savannah bug #16401.
765 * (various): Debug message cleanup. Fixes Savannah bug #16469.
767 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
769 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
770 not the end, to catch second expansion $(eval ...) defining new
771 target/prereq relationships during snap_deps.
772 Fixes Savannah bug #24622.
774 * read.c (record_files): The second-expansion "f->updating" hack
775 was not completely correct: if assumed that the target with
776 commands always had prerequisites; if one didn't then the ordering
777 was messed up. Fixed for now to use f->updating to decide whether
778 to preserve the last element in the deps list... but this whole
779 area of constructing and reversing the deps list is too confusing
780 and needs to be reworked. Fixes Savannah bug #21198.
782 2009-06-06 Paul Smith <psmith@gnu.org>
784 * hash.c (hash_insert): Remove useless test for NULL.
785 Fixes Savannah bug #21823.
787 * make.h: Move SET_STACK_SIZE determination to make.h.
788 * main.c (main): New global variable, STACK_LIMIT, holds the
789 original stack limit when make was started.
790 * job.c (start_job_command): Reset the stack limit, if we changed it.
791 Fixes Savannah bug #22010.
793 * remake.c (check_dep): Only set the target's state to not-started
794 if it's not already running. Found this while testing -j10 builds
795 of glibc: various targets were being rebuilt multiple times.
796 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
799 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
800 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
803 2009-06-04 Paul Smith <psmith@gnu.org>
805 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
807 * maintMakefile: Modify access of config and gnulib Savannah
808 modules to use GIT instead of CVS.
810 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
811 Fixes Savannah bug #24655.
813 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
814 this can happen during some invocations of $(eval ...) for example.
815 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
817 2009-06-02 Paul Smith <psmith@gnu.org>
819 * configure.in: Check for fileno()
820 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
821 for the makefile file so invocations of $(shell ...) don't inherit it.
822 Fixes Savannah bug #24277.
824 2009-06-01 Paul Smith <psmith@gnu.org>
826 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
827 expansion was handled incorrectly. Rework the default goal
828 handling to save the variable only. Remove default_goal_file and
830 * read.c (eval): Check default_goal_var, not default_goal_name.
831 * read.c (record_target_var): Don't check default_goal_file here.
833 2009-05-31 Paul Smith <psmith@gnu.org>
835 * main.c (main): Expand the .DEFAULT_GOAL variable before using
836 it, and if the multi_glob() returns nothing (say it expanded to
837 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
839 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
840 $(and ..) to the reference. Fixes Savannah bug #25694.
842 * make.1: Be clear that some recipes will be executed even with -n.
843 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
845 * doc/make.texi (Override Directive): Make more clear how
846 overrides and appends interact.
847 Elucidates part of Savannah bug #26207.
849 * read.c (record_target_var): Don't reset the origin on
850 target-specific variables; try_variable_definition() will handle
851 this correctly. Fixes Savannah bug #26207.
853 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
854 Fixes Savannah bug #25712.
856 * implicit.c (pattern_search): Keep a pointer to the beginning of
857 the filename and save that instead of the constructed pointer.
858 Fixes Savannah bug #26593.
859 Patch by Mark Seaborn <mrs@mythic-beasts.com>
861 2009-05-30 Paul Smith <psmith@gnu.org>
863 * doc/make.texi (Multi-Line): Add a description of the new abilities
864 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
865 "command sequence" vs. "recipe" syntax.
866 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
867 after a define, to create variables with those flavors.
869 2009-05-25 Paul Smith <psmith@gnu.org>
871 Reworked the parser for variable assignments to allow multiple
872 modifiers, and in any order. Also allows variable and
873 prerequisites to be modifier names ('export', 'private', etc.)
875 * NEWS: Add notes about user-visible changes.
877 * read.c (struct vmodifiers): Remember what modifiers were seen.
878 (parse_var_assignment): New function to parse variable assignments.
879 (eval): Call the new function. Handle variable assignments earlier.
881 * variable.c (parse_variable_definition): Only parse; don't create var.
882 (assign_variable_definition): Call parse, then create the var.
884 2009-05-24 Paul Smith <psmith@gnu.org>
886 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
887 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
889 2009-03-14 Eli Zaretskii <eliz@gnu.org>
891 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
892 Fixes Savannah bug #25412.
894 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
895 prototype for xmalloc.
896 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
897 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
898 Loop over an array of extensions, instead of duplicating the same
899 code inline. Use SearchPath followed by CreateFile, instead of
900 the obsolete OpenFile. Fixes Savannah bug #17277.
901 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
902 to `find_file'. Fixes Savannah bug #25662.
904 2009-03-07 Eli Zaretskii <eliz@gnu.org>
906 * function.c (func_shell): Don't close pipedes[1] if it is -1.
907 Fixes Savannah bug #20495.
909 2009-02-28 Ralf Wildenhues <address@hidden>
911 * doc/make.texi (Instead of Execution): Document interaction of
912 -t with phony targets.
914 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
916 Introduce a new keyword "private" which applies to target-specific
917 variables and prevents their values from being inherited.
919 * variable.h (struct variable): Add private_var flag to each variable.
920 Add a flag to specify which list entry switches to the parent target.

949 * job.c (construct_command_argv_internal): Avoid extra backslash
950 in batch-mode Unixy shells. Under DB_JOBS, display the contents
953 2008-05-31 Eli Zaretskii <eliz@gnu.org>
955 * README.W32.template: Remove obsolete text about non-support for
956 -jN without Unixy shell. Remove obsolete text about not supplying
957 Visual Studio project files (we do supply them). Modify text to
958 prefer GCC builds to MSC builds.
960 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
962 * doc/make.texi (Empty Targets): Fix typo.

977 `value' field is NULL.
979 2007-12-22 Eli Zaretskii <eliz@gnu.org>
981 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
983 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
984 (TEXINFOS): Value changed to `doc/make.texi'.
985 (.SUFFIXES): Use .texi instead of .texinfo.
986 (make.info, make.dvi): Depend on doc/make.texi.
987 (.texi.info): New target, instead of ".texinfo.info". Change -I
988 switch to $(MAKEINFO) to look in doc/. Use --no-split.
989 (.texi): New target, instead of ".texinfo". Change -I switch to
990 $(MAKEINFO) to look in doc/. Use --no-split.
991 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
992 switch to $(MAKEINFO) to look in doc/.
993 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

995 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
996 (html, make_1.html): New targets.
997 (.PHONY): Add "html".
998 (.SUFFIXES): Add .html.
1000 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1002 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1003 HAVE_DECL_SYS_SIGLIST.
1005 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1006 build does not use child_execute_job.
1008 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1009 export the SHELL environment variable to the child.
1011 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1013 * config.h.W32: Include sys/types.h.

1022 * doc/make.texi: Convert references to "commands", "command
1023 lines", and "command script" to "recipe".
1025 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:

1030 * remake.c (f_mtime): Print time difference values between 100 and
1031 ULONG_MAX in fixed-point notation rather than in exponention notation.
1033 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1035 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1036 a more complex value than a simple shell: if it's not a default
1037 shell now then expand it and see if is a default shell then.
1039 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1041 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1042 pathnames, with const strings.
1043 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1044 from the template (used for building from CVS, not a dist).
1046 2007-10-10 Paul Smith <psmith@gnu.org>
1048 * make.h: Add a prototype for w32_kill() (change suggested by
1049 Yongwei Wu <wuyongwei@gmail.com>).
1051 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1053 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1054 directories in Path.
1056 2007-09-12 Paul Smith <psmith@gnu.org>
1058 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1059 Provided by Diego Biurrun <diego@biurrun.de>
1060 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1061 Provided by Diego Biurrun <diego@biurrun.de>
1063 2007-09-11 Paul Smith <psmith@gnu.org>
1065 * doc/make.texi (Special Variables): Moved this into the "How to
1066 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1067 (MAKEFILE_LIST) No longer a section; this was added into the
1068 "Special Variables" section.
1069 (Rule Introduction): Reference .RECIPEPREFIX.
1070 (Simple Makefile): Ditto.
1071 (Rule Syntax): Ditto.
1072 (Command Syntax): Ditto.
1073 (Error Messages): Ditto.
1075 2007-09-10 Paul Smith <psmith@gnu.org>
1077 * commands.c (print_commands): Don't print an extra line in the
1078 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1080 * read.c (construct_include_path): Add the full string to the cache; we
1081 were chopping the last char.
1083 * NEWS: Announce the .RECIPEPREFIX special variable.
1084 * variable.c (lookup_special_var): Rename from handle_special_var().
1085 (lookup_variable): Call the new name.
1086 (set_special_var): New function: handle setting of special variables.
1087 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1090 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1091 * main.c (main): Create the .RECIPEPREFIX special variable.
1092 * read.c (eval): Remove the cmd_prefix characters from the command
1093 scripts here, so they're not stored in the commands array at all,
1094 rather than waiting and stripping them out during command construction.
1095 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1097 2007-08-15 Paul Smith <psmith@gnu.org>
1099 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1100 file has had the section info removed, so add some to make.texi
1101 before we include it.
1103 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1105 * remake.c (check_dep): Reset the target state for intermediate
1106 files. They might have been considered before but not updated

1121 2007-07-13 Paul Smith <psmith@gnu.org>
1123 * file.c (expand_deps): Use variable_buffer as the start of the
1124 buffer, not the original pointer (in case it was reallocated).
1125 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1126 Fixes Savannah bug #20452.

1151 * job.c (new_job): Add debug info to specify where make found the
1152 command script it is running to build a target.
1153 Fixes Savannah bug #18617.

1156 Add support for Objective C. Fixes Savannah bug #16389.
1157 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1159 * function.c (func_lastword): Initialize p.
1161 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1162 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1163 Dave Korn <dave.korn@artimi.com>
1165 2007-05-08 Paul Smith <psmith@gnu.org>
1167 Fix Savannah bug #19656:
1169 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1171 * make.h: Change all case-insensitive string compares to use
1172 strcasecmp() (from POSIX). If we don't have that but do have one
1173 of the others, define strcasecmp to be one of those instead. If
1174 we don't have any, declare a prototype for our own version.
1176 * misc.c (strcasecmp): Use this if we can't find any native
1177 case-insensitive string comparison function.
1178 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1179 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1181 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1182 strcasecmp() instead of stricmp().
1183 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1184 instead of strcmpi().
1185 * acinclude.m4: Remove the strcasecmp() check from here.
1187 2007-03-21 Paul Smith <psmith@gnu.org>
1189 * configure.in: Don't turn on case-insensitive file system support
1190 if --disable-... is given. Fixes Savannah bug #19348.
1192 2007-03-19 Paul Smith <psmith@gnu.org>
1194 * ALL: Use the strcache for all file name strings, or other
1195 strings which we will never free. The goal is to save memory by
1196 avoiding duplicate copies of strings. However, at the moment this
1197 doesn't save much memory in most situations: due to secondary
1198 expansion we actually save prerequisite lists twice (once before
1199 the secondary expansion, and then again after it's been parsed
1200 into individual file names in the dep list). We will resolve this
1201 in a future change, by doing the parsing up-front for targets
1202 where secondary expansion is not set.
1204 Moving things into the strcache also allows us to use const
1205 pointers in many more places.
1207 2007-01-03 Paul Smith <psmith@gnu.org>
1209 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1210 the function, not just the first. Fixes Savannah bug #18680.
1212 2006-11-18 Paul Smith <psmith@gnu.org>
1214 * strcache.c (strcache_add_len): Don't allocate a new buffer
1215 unless the string is not already nil-terminated. Technically this
1216 is a violation of the standard, since we may be passed an array
1217 that is not long enough to test one past. However, in make this
1218 is never true since we only use nil-terminated strings or
1219 sub-strings thereof.
1221 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1223 * main.c: New global cmd_prefix, defaults to '\t'.
1224 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1227 * dir.c: Constified.
1228 (dir_contents_file_exists_p): Check for an error return from
1229 readdir(), just in case.
1231 * commands.c: Constified.
1232 * default.c: Constified.
1233 * expand.c: Constified.
1234 * function.c: Partial constification.

1239 * w32/pathstuff.c: Partial constification.
1241 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1243 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1244 backslashes and drive letters as absolute.
1246 2006-10-22 Paul Smith <psmith@gnu.org>

1250 2006-10-21 Paul Smith <psmith@gnu.org>
1253 * arscan.c: Constified.
1255 2006-09-30 Paul Smith <psmith@gnu.org>
1257 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1258 point to lastword since the example was updated.
1259 Fixes Savannah bug #16304.
1260 (Secondary Expansion): Correct example description.
1261 Fixes Savannah bug #16468.
1262 (Makefile Contents): Clarify that comments cannot appear within
1263 variable references or function calls.
1264 Fixes Savannah bug #16577.
1265 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1266 Fixes Savannah bug #17701.
1267 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1268 (Prerequisite Types): Added an example of using order-only
1269 prerequisites. Fixes Savannah bug #17880.
1270 (Rule Syntax): "lise" -> "list"
1271 (Multiple Rules): ... -> @dots{}
1272 (Splitting Lines): ditto.
1274 * remake.c (update_file_1): Prereqs that don't exist should be
1275 considered changed, for the purposes of $?.
1276 Fixes Savannah bug #16051.
1278 * make.1: Remove extraneous "+".
1279 Fixes Savannah bug #16652.

1318 that don't have extended grep.
1319 (cvsclean): Use $(PERL) instead of perl.

1323 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1325 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1326 inner-scope variables don't mask outer-scope variables.

1331 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned

1387 Declare and define sh_chars_sh[].
1389 2006-03-23 Paul D. Smith <psmith@gnu.org>
1391 * configure.in: Look for build.sh.in in $srcdir so it will be
1392 built for remote configurations as well.
1394 * Makefile.am: Make sure to clean up build.sh during distclean.
1395 Fixes Savannah bug #16166.
1397 * misc.c (log_access): Takes a const char *.

1403 * implicit.c (pattern_search): Call set_file_variables only
1404 if we have prerequisites that need second expansion. Fixes
1405 Savannah bug #16140.
1407 2006-03-19 Paul D. Smith <psmith@gnu.org>
1409 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1410 memory on hosts that don't support it directly.
1412 * README.cvs: Add information on steps for making a release (to
1413 make sure I don't forget any).
1415 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1417 (die): Cleanup code was removed from here; call the new function.
1418 (main): If we are re-execing, clean up the jobserver first so we
1419 don't leak file descriptors.

1425 allow multiple concurrent runs.
1426 Patch from Joseph Myers <joseph@codesourcery.com>
1428 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1432 (copy_dep_chain): Copy stem.
1433 (free_dep_chain): Use free_dep.
1434 * read.c (record_files): Store stem in the dependency line.
1435 * file.c (expand_deps): Use stem stored in the dependency line. Use

1449 Fixes Savannah bug #15913.
1451 2006-03-09 Paul Smith <psmith@gnu.org>
1453 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1454 listed non-existent files as changed. Turns out there's a bug in
1455 the Linux kernel builds which means that this change causes
1456 everything to rebuild every time. We will re-introduce this fix
1457 in the next release, to give them time to fix their build system.
1458 Fixes Savannah bug #16002.
1459 Introduces Savannah bug #16051.

1476 2006-02-19 Paul D. Smith <psmith@gnu.org>
1478 * commands.c (set_file_variables): Realloc, not malloc, the static
1479 string values to avoid memory leaks.
1481 * expand.c (recursively_expand_for_file): Only set reading_file to
1482 an initialized value.
1484 * implicit.c (pattern_search): We need to make a copy of the stem
1485 if we get it from an intermediate dep, since those get freed.
1487 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1489 (enter_file) [VMS]: Ditto.

1494 * job.c (construct_command_argv_internal): Fix last change.
1496 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1497 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1498 the calls to _beginthreadex.
1500 * expand.c (recursively_expand_for_file): Initialize `save' to
1501 prevent compiler warnings.
1503 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1505 * job.c (construct_command_argv_internal): Don't create a temporary

1507 script file stream to text mode.

1511 * variable.c (merge_variable_set_lists): Don't try to merge the
1512 global_setlist. Not only is this useless, but it can lead to
1513 circularities in the linked list, if global_setlist->next in one
1514 list gets set to point to another list which also ends in
1516 Fixes Savannah bug #15757.
1518 2006-02-15 Paul D. Smith <psmith@gnu.org>
1520 Fix for Savannah bug #106.
1522 * expand.c (expanding_var): Keep track of which variable we're
1523 expanding. If no variable is being expanded, it's the same as
1525 * make.h (expanding_var): Declare it.
1526 * expand.c (recursively_expand_for_file): Set expanding_var to the
1527 current variable we're expanding, unless there's no file info in
1528 it (could happen if it comes from the command line or a default
1529 variable). Restore it before we exit.

1541 * read.c (eval): Even if the included filenames expands to the
1542 empty string we still need to free the allocated buffer.
1544 * implicit.c (pattern_search): If we allocated a variable set for
1545 an impossible file, free it.
1546 * variable.c (free_variable_set): New function.
1547 * variable.h: Declare it.
1549 * read.c (read_all_makefiles): Makefile names are kept in the
1550 strcache, so there's never any need to alloc/free them.
1553 * main.c (main): Add "archives" to the .FEATURES variable if
1554 archive support is enabled.

1565 * (ALL FILES): Updated copyright and license notices.
1567 2006-02-10 Paul D. Smith <psmith@gnu.org>
1569 A new internal capability: the string cache is a read-only cache
1570 of strings, with a hash table interface for fast lookup. Nothing
1571 in the cache will ever be freed, so there's no need for reference
1572 counting, etc. This is the beginning of a full solution for
1573 Savannah bug #15182, but for now we only store makefile names here.
1575 * strcache.c: New file. Implement a read-only string cache.
1576 * make.h: Add prototypes for new functions.
1577 * main.c (initialize_global_hash_tables): Initialize the string cache.
1578 (print_data_base): Print string cache stats.

1584 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1585 directory time stamp didn't change, except on FAT filesystems.

1602 * job.c (reap_children): Use cached dontcare flag instead of the
1603 one in struct file. Fixes Savannah bug #15641.
1605 2006-02-06 Paul D. Smith <psmith@gnu.org>
1607 * vpath.c (selective_vpath_search): If the file we find has a
1608 timestamp from -o or -W, use that instead of the real time.
1609 * remake.c (f_mtime): If the mtime is a special token from -o or
1610 -W, don't overwrite it with the real mtime.
1611 Fixes Savannah bug #15341.
1613 Updates from Markus Mauhart <qwe123@chello.at>:
1615 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1616 (process_signal, process_last_err, process_exit_code): Manage
1617 invalid handle values.
1618 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1619 manage invalid handles; remove them.
1620 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1621 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1622 * README.cvs: Updates for building from CVS.
1624 2006-02-05 Paul D. Smith <psmith@gnu.org>
1626 * file.c (enter_file): Keep track of the last double_colon entry,
1627 to avoid walking the list every time we want to add a new one.
1628 Fixes Savannah bug #15533.
1629 * filedef.h (struct file): Add a new LAST pointer.
1631 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1632 the comparison. For 64-bits systems the result of the subtraction
1633 might not fit into an int. Use comparison instead.
1634 Fixes Savannah bug #15534.
1636 * doc/make.texi: Update the chapter on writing commands to reflect
1637 the changes made in 3.81 for backslash/newline and SHELL handling.
1639 2006-02-01 Paul D. Smith <psmith@gnu.org>
1641 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1657 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1659 * remake.c (update_goal_chain): Set g->changed instead of
1660 incrementing it, as it is only 8-bit wide, and could overflow if
1661 many commands got started in update_file.
1663 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1665 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1666 MAXIMUM_WAIT_OBJECTS.
1667 (process_wait_for_any_private): Change dimension of handles[]
1668 array to MAXIMUM_WAIT_OBJECTS.
1669 (process_used_slots): New function.
1670 (process_register): Don't register more processes than the
1671 available number of slots.
1672 (process_easy): Don't start new processes if all slots are used up.
1674 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1675 are already more children than sub_proc.c can handle, behave as if
1676 the load were too high.
1677 (start_job_command): Fix a typo in error message when process_easy
1680 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1682 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1683 the shell is not sh.exe.
1685 * job.c (create_batch_file): Renamed from create_batch_filename;
1686 all callers changed. Don't close the temporary file; return its
1687 file descriptor instead. New arg FD allows to return the file
1689 (construct_command_argv_internal): Use _fdopen instead of fopen to
1690 open the batch file.
1692 2006-01-04 Paul D. Smith <psmith@gnu.org>
1694 * readme.vms: Updates for case-insensitive VMS file systems from
1695 Hartmut Becker <Hartmut.Becker@hp.com>.
1696 * dir.c (vms_hash): Ditto.

1706 * remake.c (update_file_1): Mark a prerequisite changed if it
1709 * read.c (eval): Be sure to strip off trailing whitespace from the
1710 prerequisites list properly. Also, initialize all fields in
1711 struct dep when creating a new one.
1713 2005-12-28 Paul D. Smith <psmith@gnu.org>
1715 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1716 disable warnings for MSC.
1717 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1719 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1721 * doc/make.texi (Execution): Add a footnote about changes in
1722 handling of backslash-newline sequences. Mention the differences
1723 on MS-DOS and MS-Windows.
1725 * NEWS: More details about building the MinGW port and a pointer
1726 to README.W32. Fix the section name that describes the new
1727 backward-incompatible processing of backslash-newline sequences.
1728 The special processing of SHELL set to "cmd" is only relevant to
1729 MS-Windows, not MS-DOS.
1731 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1733 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1734 to DWORD, to avoid compiler warnings.
1735 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1736 use %ld in format, to avoid compiler warnings.
1738 * doc/make.texi (Special Targets): Fix a typo.
1739 (Appending): Fix cross-reference to Setting.
1740 (Special Variables, Secondary Expansion, File Name Functions)
1741 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1742 periods after a sentence.
1743 (Execution): Add @: after "e.g.".
1744 (Environment): Fix punctuation.
1745 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1746 (Shell Function, Target-specific): Add @: after "vs."
1748 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1750 * read.c (record_target_var): Initialize variable's export field
1751 with v_default instead of leaving it "initialized" by whatever
1752 garbage happened to be on the heap.
1754 2005-12-12 Paul D. Smith <psmith@gnu.org>
1756 * make.1: Fix some display errors and document all existing options.
1757 Patch by Mike Frysinger <vapier@gentoo.org>.
1759 2005-12-11 Paul D. Smith <psmith@gnu.org>
1761 * implicit.c (pattern_search): If 2nd expansion is not set for
1762 this implicit rule, replace the pattern with the stem directly,
1763 and don't re-expand the variable list. Along with the other
1764 .SECONDEXPANSION changes below, fixes bug #13781.
1766 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1768 * implicit.c (pattern_search): Mark other files that this rule
1769 builds as targets so that they are not treated as intermediates
1770 by the pattern rule search algorithm. Fixes bug #13022.
1772 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1774 * remake.c (notice_finished_file): Propagate the change of
1775 modification time to all the double-colon entries only if
1776 it is the last one to be updated. Fixes bug #14334.
1778 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1780 * function.c (func_flavor): Implement the flavor function which
1781 returns the flavor of a variable.
1782 * doc/make.texi (Functions for Transforming Text): Document it.
1783 * NEWS: Add it to the list of new functions.
1785 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1787 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1789 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1790 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1792 2005-10-26 Paul Smith <psmith@gnu.org>
1794 * read.c (record_files): Don't set deps flags if there are no deps.
1795 * maintMakefile: We only need to build the templates when we are
1796 creating a distribution, so don't do it for "all".
1798 2005-10-24 Paul D. Smith <psmith@gnu.org>
1800 Make secondary expansion optional: its enabled by declaring the
1801 special target .SECONDEXPANSION.
1803 * NEWS: Update information on second expansion capabilities.
1804 * doc/make.texi (Secondary Expansion): Document the
1805 .SECONDEXPANSION special target and its behavior.
1806 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1807 prerequisite list was found in a static pattern rule.
1808 (free_dep_chain): Declare a prototype.
1809 * file.c (parse_prereqs): New function: break out some complexity
1811 (expand_deps): If we aren't doing second expansion, replace % with
1812 the stem for static pattern rules. Call the new function.
1813 * filedef.h (parse_prereqs): Declare a prototype.
1814 * implicit.c (pattern_search): Initialize the new staticpattern
1816 * main.c (second_expansion): Declare a global variable to remember
1817 if the special target has been seen. Initialize the new
1818 staticpattern field for prerequisites.
1819 * make.h: Extern for second_expansion.
1820 * misc.c (free_dep_chain): New function: frees a struct dep list.
1821 * read.c (read_all_makefiles): Initialize the staticpattern field.
1822 (eval_makefile): Ditto.
1823 (record_files): Check for the .SECONDEXPANSION target and set
1824 second_expansion global if it's found.
1825 Use the new free_dep_chain() instead of doing it by hand.
1826 Set the staticpattern field for prereqs of static pattern targets.
1828 2005-10-16 Paul D. Smith <psmith@gnu.org>
1830 * main.c (main): Set CURDIR to be a file variable instead of a
1831 default, so that values of CURDIR inherited from the environment
1832 won't override the make value.
1834 2005-09-26 Paul D. Smith <psmith@gnu.org>
1836 * job.c (construct_command_argv_internal): If the line is empty
1837 remember to free the temporary argv strings.
1840 2005-09-16 Paul D. Smith <psmith@gnu.org>
1842 * job.c (start_job_command): The noerror flag is a boolean (single
1843 bit); set it appropriately.
1844 Reported by Mark Eichin <eichin@metacarta.com>
1846 2005-08-29 Paul D. Smith <psmith@gnu.org>
1848 * function.c (func_error): On Windows, output from $(info ...)
1849 seems to come in the wrong order. Try to force it with fflush().
1851 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1853 * read.c (record_files): Move code that sets stem for static
1854 pattern rules out of the if (!two_colon) condition so it is
1855 also executed for two-colon rules. Fixes Savannah bug #13881.
1857 2005-08-08 Paul D. Smith <psmith@gnu.org>
1859 * make.h: Don't test that __STDC__ is non-0. Some compilers
1860 (Windows for example) set it to 0 to denote "ISO C + extensions".
1863 2005-08-07 Paul D. Smith <psmith@gnu.org>
1865 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1866 conditional (slightly different version of a fix from Eli).
1868 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1869 If make is running in parallel without -k and two jobs die in a
1870 row, but not too close to each other, then make will quit without
1871 waiting for the rest of the jobs to die.
1873 * main.c (die): Don't reset err before calling reap_children() the
1874 second time: we still want it to be in the error condition.
1875 * job.c (reap_children): Use a static variable, rather than err,
1876 to control whether or not the error message should be printed.
1878 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1880 * w32/subproc/sub_proc.c: Include signal.h.
1881 (process_pipe_io, process_file_io): Pass a pointer to a local
1882 DWORD variable to GetExitCodeProcess. If the exit code is
1883 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1885 * job.c [WINDOWS32]: Include windows.h.
1886 (main_thread) [WINDOWS32]: New global variable.
1887 (reap_children) [WINDOWS32]: Get the handle for the main thread
1888 and store it in main_thread.
1890 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1891 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1892 doing anything else. When we are done, close the main thread
1893 handle and exit with status 130.
1895 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1897 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1900 * main.c (find_and_set_default_shell): If found a DOSish shell,
1901 set sh_found and the value of default_shell, and report the
1902 findings in debug mode.
1904 * job.c (construct_command_argv_internal): Check unixy_shell, not
1905 no_default_sh_exe, to decide whether to use Unixy or DOSish
1908 * README.W32: Update with info about the MinGW build.
1910 * build_w32.bat: Support MinGW.
1912 * w32/subproc/build.bat: Likewise.
1914 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1915 printing DWORD args.
1917 * function.c (windows32_openpipe): Fix format strings for printing
1920 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1922 (start_job_command): Fix format string for printing the result of
1924 (start_job_command) [WINDOWS32]: Do not define.
1925 (exec_command): Fix format string for printing HANDLE args.
1927 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1928 to avoid compiler warnings.
1929 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1930 (Note: some of these fixes were submitted independently by J. Grant)
1932 2005-07-30 J. Grant <jg@jguk.org>
1934 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1935 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1936 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1938 2005-07-15 Paul Smith <psmith@gnu.org>
1940 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1941 we don't have a POSIX shell, then revert to the old
1942 backslash-newline behavior (where they are stripped).
1945 2005-07-08 Paul D. Smith <psmith@gnu.org>
1947 * config.h.W32.template: Reorder to match the standard config.h,
1948 for easier comparisons.
1949 From J. Grant <jg@jguk.org>
1951 * maintMakefile: Remove .dep_segment before overwriting it, in
1952 case it's not writable or noclobber is set.
1953 * expand.c (variable_expand_string): Cast result of pointer
1954 arithmetic to avoid a warning.
1955 * main.c (switches): Add full-fledged final initializer.
1957 2005-07-06 Paul D. Smith <psmith@gnu.org>
1959 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1960 * signame.c (strsignal): If we found _sys_siglist[] or
1961 __sys_siglist[] use those instead of sys_siglist[].
1962 From Albert Chin <china@thewrittenword.com>
1964 2005-07-04 Paul D. Smith <psmith@gnu.org>
1966 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1967 globfree(); set up to use the GNU versions.
1968 From Martin Zinser <zinser@zinser.no-ip.info>
1970 2005-07-03 Paul D. Smith <psmith@gnu.org>
1972 From J. Grant <jg@jguk.org>:
1974 * README.W32.template: Update the Windows and tested MSVC versions.
1975 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1976 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1977 * build_w32.bat: Ditto.
1978 * w32/subproc/build.bat: Ditto.
1980 2005-06-28 Paul D. Smith <psmith@gnu.org>
1982 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1983 declaration was checked but not present.
1985 2005-06-27 Paul D. Smith <psmith@gnu.org>
1987 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1988 to unsigned long. Fixes Savannah bug #13550.
1990 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1991 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1992 Fixes Savannah bug #13551.
1994 2005-06-26 Paul D. Smith <psmith@gnu.org>
1996 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1997 it if ANSI_STRING is not set.
1999 2005-06-25 Paul D. Smith <psmith@gnu.org>
2001 * read.c (eval): If no filenames are passed to any of the
2002 "include" variants, don't print an error.
2003 * doc/make.texi (Include): Document this.
2004 Fixes Savannah bug #1761.
2006 * job.c (construct_command_argv_internal): Sanitize handling of
2007 backslash/newline pairs according to POSIX: that is, keep the
2008 backslash-newline in the command script, but remove a following
2009 TAB character, if present. In the fast path, make sure that the
2010 behavior matches what the shell would do both inside and outside
2011 of quotes. In the slow path, quote the backslash and put a
2012 literal newline in the string.
2013 Fixes Savannah bug #1332.
2014 * doc/make.texi (Execution): Document the new behavior and give
2016 * NEWS: Make a note of the new behavior.
2018 * make.h [WINDOWS32]: #include <direct.h>.
2019 Fixes Savannah bug #13478.
2021 * remake.c (name_mtime): If the stat() of a file fails and the -L
2022 option was given and the file is a symlink, take the best mtime of
2023 the symlink we can get as the mtime of the file and don't fail.
2024 Fixes Savannah bug #13280.
2026 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2027 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2028 inside a variable reference. Make this function static as it's
2030 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2031 parsing an unexpanded line looking for semicolons.
2032 Fixes Savannah bug #1454.
2033 * misc.c (remove_comments): Move this to read.c and make it static
2034 as it's only used there. Call find_char_unquote() with new arg.
2035 * make.h: Remove prototypes for find_char_unquote() and
2036 remove_comments() since they're static now.
2038 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2039 its export flag and obtain its value. When we need to re-exec,
2040 increment the value and add it into the environment.
2041 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2042 * NEWS: Mention MAKE_RESTARTS.
2043 * main.c (always_make_set): New variable. Change the -B option to
2044 set this one instead.
2045 (main): When checking makefiles, only set always_make_flag if
2046 always_make_set is set AND the restarts flag is 0. When building
2047 normal targets, set it IFF always_make_set is set.
2048 (main): Avoid infinite recursion with -W, too: only set what-if
2049 files to NEW before we check makefiles if we've never restarted
2050 before. If we have restarted, set what-if files to NEW _after_ we
2052 Fixes Savannah bug #7566:
2054 2005-06-17 Paul D. Smith <psmith@gnu.org>
2056 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2057 in the prerequisites list.
2059 2005-06-12 Paul D. Smith <psmith@gnu.org>
2061 Fix Savannah bug # 1328.
2063 * configure.in: Check for atexit().
2064 * misc.c (close_stdout): Test stdout to see if writes to it have
2065 failed. If so, be sure to exit with a non-0 error code. Based on
2066 code found in gnulib.
2067 * make.h: Prototype.
2068 * main.c (main): Install close_stdout() with atexit().
2070 2005-06-10 Paul D. Smith <psmith@gnu.org>
2072 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2074 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2075 headers; make vmsWaitForChildren() static; extern vmsify().
2076 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2077 Don't create child_execute_job() here (it's in vmsjobs.c).
2078 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2080 2005-06-09 Paul D. Smith <psmith@gnu.org>
2082 * variable.c (push_new_variable_scope): File variables point
2083 directly to the global_setlist variable. So, inserting a new
2084 scope in front of that has no effect on those variables: they
2085 don't go through current_variable_set_list. If we're pushing a
2086 scope and the current scope is global, push it "the other way" so
2087 that the new setlist is in the global_setlist variable, and
2088 next points to a new setlist with the global variable set.
2089 (pop_variable_scope): Properly undo a push with the new
2091 Fixes Savannah bug #11913.
2093 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2095 * job.c (reap_children): Don't die of the command failed but
2096 the dontcare flag is set. Fixes Savannah bug #13216.
2098 * implicit.c (pattern_search): When creating a target from
2099 an implicit rule match, lookup pattern target and set precious
2100 flag in a newly created target. Fixes Savannah bug #13218.
2102 2005-05-13 Paul D. Smith <psmith@gnu.org>
2104 Implement "if... else if... endif" syntax.
2106 * read.c (eval): Push all checks for conditional words ("ifeq",
2107 "else", etc.) down into the conditional_line() function.
2108 (conditional_line): Rework to allow "else if..." clause. New
2109 return value -2 for lines which are not conditionals. The
2110 ignoring flag can now also be 2, which means "already parsed a
2111 true branch". If that value is seen no other branch of this
2112 conditional can be considered true. In the else parsing if there
2113 is extra text after the else, invoke conditional_line()
2114 recursively to see if it's another conditional. If not, it's an
2115 error. If so, raise the conditional value to this level instead
2116 of creating a new conditional nesting level. Special check for
2117 "else" and "endif", which aren't allowed on the "else" line.
2118 * doc/make.texi (Conditional Syntax): Document the new syntax.
2120 2005-05-09 Paul D. Smith <psmith@gnu.org>
2122 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2123 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2124 recurses to the w32 directory, even on non-Windows systems. Use
2125 the method suggested in the automake manual.
2126 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2127 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2129 2005-05-07 Paul D. Smith <psmith@gnu.org>
2131 * main.c (die): If we're dying with a fatal error (not that a
2132 command has failed), write back any leftover tokens before we go.
2134 * job.c (set_child_handler_action_flags): If there are jobs
2135 waiting for the load to go down, set an alarm to go off in 1
2136 second. This allows us to wake up from a potentially long-lasting
2137 read() and start a new job if the load has gone down. Turn it off
2139 (job_noop): Dummy signal handler function.
2140 (new_job): Invoke it with the new semantics.
2142 * docs/make.texi: Document secondary expansion. Various cleanups
2145 2005-05-03 Paul D. Smith <psmith@gnu.org>
2147 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2148 the targets which are to ultimately be made are called "goals";
2149 see the GNU make manual. Also, MAKECMDGOALS, etc.
2151 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2152 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2153 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2155 2005-05-02 Paul D. Smith <psmith@gnu.org>
2157 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2158 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2159 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2160 functions to vmsjobs.c. #include it into jobs.c.
2162 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2163 jobserver tokens. I found that this happens when an exported
2164 recursive variable contains a $(shell ...) function reference: in
2165 this situation we could "forget" to write back a token.
2167 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2168 we have. It's not reliable to depend on the number of children in
2169 our linked list so keep a separate count.
2170 (new_job): Check jobserver_tokens rather than children &&
2171 waiting_jobs. Increment jobserver_tokens when we get one.
2172 (free_child): If jobserver_tokens is 0, internal error. If it's
2173 >1, write a token back to the jobserver pipe (we don't write a
2174 token for the "free" job). Decrement jobserver_tokens.
2176 * main.c: Add variable master_job_slots.
2177 (main): Set it to hold the number of jobs requested if we're the
2178 master process, when using the jobserver.
2179 (die): Sanity checks: first test jobserver_tokens to make sure
2180 this process isn't holding any tokens we didn't write back.
2181 Second, if master_job_slots is set count the tokens left in the
2182 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2184 2005-04-24 Paul D. Smith <psmith@gnu.org>
2186 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2187 with -l# can lose jobserver tokens, because waiting jobs are not
2188 consulted properly when checking for the "free" token.
2190 * job.c (free_child): Count waiting_jobs as having tokens.
2191 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2192 handle jobs waiting for the load to drop.
2194 2005-04-23 Paul D. Smith <psmith@gnu.org>
2196 * main.c (main): Be careful to not core if a variable setting in
2197 the environment doesn't contain an '='. This is illegal but can
2198 happen in broken setups.
2199 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2201 2005-04-12 Paul D. Smith <psmith@gnu.org>
2203 The second expansion feature causes significant slowdown. Timing
2204 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2205 read the makefile before the feature, to 11+s to do the same
2206 operations after the feature. Additionally, memory usage
2207 increased drastically. To fix this I added some intelligence that
2208 avoids the overhead of the second expansion unless it's required.
2210 * dep.h: Add a new boolean field, need_2nd_expansion.
2212 * read.c (eval): When creating the struct dep for the target,
2213 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2214 (record_files): If there's a "%" in a static pattern rule, it gets
2215 converted to "$*" so set need_2nd_expansion to 1.
2217 * file.c (expand_deps): Rework to be more efficient. Only perform
2218 initialize_file_variables(), set_file_variables(), and
2219 variable_expand_for_file() if the need_2nd_expansion is set.
2221 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2222 (pattern_search): Ditto.
2223 * main.c (handle_non_switch_argument): Ditto.
2225 * read.c (read_all_makefiles): Ditto.
2226 (eval_makefile): Ditto.
2228 2005-04-07 Paul D. Smith <psmith@gnu.org>
2230 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2231 * variable.c (sync_Path_environment): Ditto.
2232 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2234 * main.c (main): Define the .FEATURES variable.
2235 * NEWS: Announce .FEATURES.
2236 * doc/make.texi (Special Variables): Document .FEATURES.
2238 * remake.c (check_dep): If a file is .PHONY, update it even if
2239 it's marked intermediate. Fixes Savannah bug #12331.
2241 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2243 * file.c (expand_deps): Factor out the second expansion and
2244 prerequisite line parsing logic from snap_deps().
2246 * file.c (snap_deps): Use expand_deps(). Expand and parse
2247 prerequisites of the .SUFFIXES special target first. Fixes
2248 Savannah bug #12320.
2250 2005-03-13 Paul D. Smith <psmith@gnu.org>
2252 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2255 2005-03-11 Paul D. Smith <psmith@gnu.org>
2257 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2258 available, not undefined (from Earnie Boyd).
2260 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2262 * implicit.c (pattern_search): Mark an intermediate target as
2263 precious if it happened to be a prerequisite of some (other)
2264 target. Fixes Savannah bug #12267.
2266 2005-03-09 Paul D. Smith <psmith@gnu.org>
2268 * read.c (eval_makefile): Add alloca(0).
2269 (eval_buffer): Ditto.
2271 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2273 * main.c (main): Use o_file instead of o_default when defining
2274 the .DEFAULT_TARGET special variable.
2275 * read.c (eval): Use define_variable_global() instead of
2276 define_variable() when setting new value for the .DEFAULT_TARGET
2277 special variable. Fixes Savannah bug #12266.
2279 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2281 * imlicit.c (pattern_search): Mark files for which an implicit
2282 rule has been found as targets. Fixes Savannah bug #12202.
2284 2005-03-04 Paul D. Smith <psmith@gnu.org>
2287 * doc/make.texi (Automatic Variables): Document $|.
2289 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2291 * read.c (record_files): Instead of substituting % with
2292 actual stem value in dependency list replace it with $*.
2293 This fixes stem triple expansion bug.
2295 * implicit.c (pattern_search): Copy stem to a separate
2296 buffer and make it a properly terminated string. Assign
2297 this buffer instead of STEM (which is not terminated) to
2298 f->stem. Instead of substituting % with actual stem value
2299 in dependency list replace it with $*. This fixes stem
2300 triple expansion bug.
2302 2005-03-01 Paul D. Smith <psmith@gnu.org>
2304 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2305 on Windows, as it takes a handle not a pid. Just exit.
2306 Fix from patch #3679, provided by Alessandro Vesely.
2308 * configure.in: Update check for sys_siglist[] from autoconf manual.
2309 * signame.c (strsignal): Update to use the new autoconf macro.
2311 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2313 * read.c (record_files): Add a check for the list of prerequisites
2314 of a static pattern rule being empty. Fixes Savannah bug #12180.
2316 2005-02-28 Paul D. Smith <psmith@gnu.org>
2318 * doc/make.texi (Text Functions): Update docs to allow the end
2319 ordinal for $(wordlist ...) to be 0.
2320 * function.c (func_wordlist): Fail if the start ordinal for
2321 $(wordlist ...) is <1. Matches documentation.
2322 Resolves Savannah support request #103195.
2324 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2325 previously we were stopping when !-q, exactly the opposite. This
2326 has been wrong since version 1.34, in 1994!
2327 (update_file): If we got an error don't break out to run more
2328 double-colon rules: just return immediately.
2329 Fixes Savannah bug #7144.
2331 2005-02-27 Paul D. Smith <psmith@gnu.org>
2333 * misc.c (end_of_token): Make argument const.
2334 * make.h: Update prototype.
2336 * function.c (abspath, func_realpath, func_abspath): Use
2337 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2338 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2339 * read.c (record_files): Ditto.
2340 * variable.c (do_variable_definition): Ditto.
2342 * function.c (func_error): Create a new function $(info ...) that
2343 simply prints the message to stdout with no extras.
2344 (function_table_init): Add new function to the table.
2345 * NEWS: Add $(info ...) reference.
2346 * doc/make.texi (Make Control Functions): Document it.
2348 New feature: if the system supports symbolic links, and the user
2349 provides the -L/--check-symlink-time flag, then use the latest
2350 mtime between the symlink(s) and the target file.
2352 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2353 readlink(). If both are available, define MAKE_SYMLINKS.
2354 * main.c: New variable: check_symlink_flag.
2355 (usage): Add a line for -L/--check-symlink-times to the help string.
2356 (switches): Add -L/--check-symlink-times command line argument.
2357 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2358 print a warning and disable it again.
2359 * make.h: Declare check_symlink_flag.
2360 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2361 if the file is a symlink then check each link in the chain and
2362 choose the NEWEST mtime we find as the mtime for the file. The
2363 newest mtime might be the file itself!
2364 * NEWS: Add information about this new feature.
2365 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2367 Avoid core dumps described in Savannah bug # 12124:
2369 * file.c: New variable snapped_deps remember whether we've run
2371 (snap_deps): Set it.
2372 * filedef.h: Extern it.
2373 * read.c (record_files): Check snapped_deps; if it's set then
2374 we're trying to eval a new target/prerequisite relationship from
2375 within a command script, which we don't support. Fatal.
2377 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2379 Implementation of the .DEFAULT_TARGET special variable.
2381 * read.c (eval): If necessary, update default_target_name when
2383 * read.c (record_files): Update default_target_file if
2384 default_target_name has changed.
2385 * main.c (default_target_name): Define.
2386 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2387 default_target_name is set use default_target_file as a root
2389 * filedef.h (default_target_name): Declare.
2390 * dep.h (free_dep_chain):
2391 * misc.c (free_dep_chain): Change to operate on struct nameseq
2392 and change name to free_ns_chain.
2393 * file.c (snap_deps): Update to use free_ns_chain.
2395 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2397 Implementation of the second expansion in explicit rules,
2398 static pattern rules and implicit rules.
2400 * read.c (eval): Refrain from chopping up rule's dependencies.
2401 Store them in a struct dep as a single dependency line. Remove
2402 the code that implements SySV-style automatic variables.
2404 * read.c (record_files): Adjust the code that handles static
2405 pattern rules to expand all percents instead of only the first
2406 one. Reverse the order in which dependencies are stored so that
2407 when the second expansion reverses them again they appear in
2408 the makefile order (with some exceptions, see comments in
2409 the code). Remove the code that implements SySV-style automatic
2412 * file.c (snap_deps): Implement the second expansion and chopping
2413 of dependency lines for explicit rules.
2415 * implicit.c (struct idep): Define an auxiliary data type to hold
2416 implicit rule's dependencies after stem substitution and
2419 * implicit.c (free_idep_chain): Implement.
2421 * implicit.c (get_next_word): Implement helper function for
2422 parsing implicit rule's dependency lines into words taking
2423 into account variable expansion requests. Used in the stem
2426 * implicit.c (pattern_search): Implement the second expansion
2427 for implicit rules. Also fixes bug #12091.
2429 * commands.h (set_file_variables): Declare.
2430 * commands.c (set_file_variables): Remove static specifier.
2432 * dep.h (free_dep_chain): Declare.
2433 * misc.c (free_dep_chain): Implement.
2435 * variable.h (variable_expand_for_file): Declare.
2436 * expand.c (variable_expand_for_file): Remove static specifier.
2438 * make.h (strip_whitespace): Declare.
2439 * function.c (strip_whitespace): Remove static specifier.
2441 2005-02-26 Paul D. Smith <psmith@gnu.org>
2443 * main.c (main): Check for ferror() when reading makefiles from stdin.
2444 Apparently some shells in Windows don't close pipes properly and
2447 2005-02-24 Jonathan Grant <jg@jguk.org>
2449 * configure.in: Add MinGW configuration options, and extra w32 code
2451 * Makefile.am: Add MinGW configuration options, and extra w32 code
2453 * main.c: Determine correct program string (after last \ without .exe).
2454 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2456 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2457 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2458 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2459 environment support.
2461 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2463 * function.c (func_shell): When initializing error_prefix, check
2464 that reading file name is not null. This fixes long-standing
2465 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2467 2005-02-09 Paul D. Smith <psmith@gnu.org>
2469 * maintMakefile: Update the CVS download URL to simplify them.
2470 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2471 downloading the .texi files from Savannah now.
2473 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2475 * main.c (handle_non_switch_argument): Only add variables to
2476 command_variables if they're not already there: duplicate settings
2477 waste space and can be confusing to read.
2479 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2480 this header is never included by non-WINDOWS32 code, and it
2481 requires <config.h> to define which isn't always included first.
2483 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2484 testing MINGW32 versions.
2486 * main.c (log_working_directory): flush stdout to be sure the WD
2487 change is printed before any stderr messages show up.
2489 2005-02-01 Paul D. Smith <psmith@gnu.org>
2491 * maintMakefile (po_repo): Update the GNU translation site URL.
2493 2004-12-01 Paul D. Smith <psmith@gnu.org>
2495 * main.c (main): Change char* env_shell to struct variable shell_var.
2496 * variable.c (target_environment): Use new shell_var.
2498 2004-11-30 Paul D. Smith <psmith@gnu.org>
2500 * configure.in: The old way we avoided creating build.sh from
2501 build.sh.in before build.sh.in exists doesn't work anymore; we
2502 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2503 the help!). This also keeps automake from complaining.
2504 * Makefile.am (README): Add a dummy target so automake won't
2505 complain that this file doesn't exist when we checkout from CVS.
2506 * maintMakefile (.dep_segment): Rewrite this rule since newer
2507 versions of automake don't provide DEP_FILES.
2509 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2511 Implementation of `realpath' and `abspath' built-in functions.
2513 * configure.in: Check for realpath.
2514 * function.c (abspath): Return an absolute file name that does
2515 not contain any `.' or `..' components, nor repeated `/'.
2516 * function.c (func_abspath): For each name call abspath.
2517 * function.c (func_realpath): For each name call realpath
2518 from libc or delegate to abspath if realpath is not available.
2519 * doc/make.texi (Functions for File Names): Document new functions.
2520 * doc/make.texi (Quick Reference): Ditto.
2522 2004-11-28 Paul D. Smith <psmith@gnu.org>
2524 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2525 arguments. Fixes bug #10252.
2527 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2529 * main.c (main): Set SHELL to v_noexport by default. Remember the
2530 original environment setting of SHELL in the env_shell variable.
2531 * main.h: Export new env_shell variable.
2532 * variable.c (target_environment): If we find a v_noexport
2533 variable for SHELL, add a SHELL variable with the env_shell value.
2534 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2535 * doc/make.texi (Variables/Recursion): Ditto.
2537 2004-11-28 Paul D. Smith <psmith@gnu.org>
2539 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2540 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2541 Patch by Alessandro Vesely.
2543 2004-11-12 Paul D. Smith <psmith@gnu.org>
2545 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2546 the command line if it's inside a string.
2547 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2549 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2551 * function.c (func_lastword): New function: return last word
2552 from the list of words.
2553 * doc/make.texi: Document $(lastword ). Fix broken links in
2554 Quick Reference section.
2556 2004-10-06 Paul D. Smith <psmith@gnu.org>
2558 Apply patch from Alessandro Vesely, provided with bug # 9748.
2559 Fix use of tmpnam() to work with Borland C.
2561 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2562 construction of a temporary filename, and call new function
2563 create_batch_filename().
2564 (create_batch_filename) [WINDOWS32]: New function to create a
2567 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2569 * read.c (record_target_var): Expand simple pattern-specific
2571 * variable.c (initialize_file_variables): Do not expand simple
2572 pattern-specific variable.
2574 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2576 * remake.c (update_file_1): When rebuilding makefiles inherit
2577 dontcare flag from a target that triggered update.
2579 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2581 * variable.c (initialize_file_variables): Mark pattern-specific
2582 variable as a per-target and copy export status.
2584 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2586 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2588 * implicit.c (pattern_search): When considering an implicit rule's
2589 prerequisite check that it is actually a target rather then
2590 just an entry in the file hashtable.
2592 2004-09-21 Paul D. Smith <psmith@gnu.org>
2594 * read.c (readstring): Fix some logic errors in backslash handling.
2595 (eval): Remove some unnecessary processing in buffer handling.
2596 (record_target_var): Assert that parse_variable_definition() succeeded.
2597 Reported by: Markus Mauhart <qwe123@chello.at>.
2599 * misc.c: Removed the sindex() function. All instances of this
2600 function were trivially replaceable by the standard strstr()
2601 function, and that function will always have better (or certainly
2602 no worse) performance than the very simple-minded algorithm
2603 sindex() used. This can matter with complex makefiles.
2604 * make.h: Remove the prototype for sindex().
2605 * function.c (subst_expand): Convert sindex() call to strstr().
2606 This means we no longer need to track the TLEN value so remove that.
2607 (func_findstring): Convert sindex() to strstr().
2608 * commands.c (chop_commands): Convert sindex() calls to strstr().
2609 Suggested by: Markus Mauhart <qwe123@chello.at>.
2611 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2612 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2613 If SHELL is set to CMD.EXE then assume it's batch-mode and
2614 non-unixy. I wrote the code differently from the patch, though,
2615 to make it safer. This also resolves bug #9174.
2617 2004-09-20 Paul D. Smith <psmith@gnu.org>
2619 * expand.c (variable_expand_string): Modify to invoke
2620 patsubst_expand() instead of subst_expand(); the latter didn't
2621 handle suffix patterns correctly.
2622 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2623 was used only from variable_expand_string() and is no longer used
2625 (func_subst): Ditto, on call to subst_expand().
2626 (patsubst_expand): Require the percent pointers to point to the
2627 character after the %, not to the % itself.
2628 * read.c (record_files): New call criteria for patsubst_expand().
2629 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2630 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2632 2004-09-19 Paul D. Smith <psmith@gnu.org>
2634 * function.c (subst_expand): Fix a check in by_word: look for a
2635 previous blank if we're beyond the beginning of the string, not
2636 the beginning of the word.
2637 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2639 2004-05-16 Paul D. Smith <psmith@gnu.org>
2641 * remake.c (update_goal_chain): Change the argument specifying
2642 whether we're rebuilding makefiles to be a global variable,
2643 REBUILDING_MAKEFILES.
2644 (complain): Extract the code that complains about no rules to make
2645 a target into a separate function.
2646 (update_file_1): If we tried to rebuild a file during the makefile
2647 rebuild phase and it was dontcare, then no message was printed.
2648 If we then try to build the same file during the normal build,
2649 print a message this time.
2650 (remake_file): Don't complain about un-remake-able files when
2651 we're rebuilding makefiles.
2653 2004-05-11 Paul D. Smith <psmith@gnu.org>
2655 * job.c (construct_command_argv_internal): OS/2 patches from
2656 Andreas Buening <andreas.buening@nexgo.de>.
2658 2004-05-10 Paul D. Smith <psmith@gnu.org>
2660 * remake.c (update_file): Don't walk the double-colon chain unless
2661 this is a double-colon rule. Fix suggested by Boris Kolpackov
2662 <boris@kolpackov.net>.
2664 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2665 * readme.vms: New section describing OpenVMS support and issues.
2666 * default.c (default_variables): Add support for IA64.
2667 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2668 without some privilege aborts make with the error
2669 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2670 pressing Ctrl+Y and the input device is no terminal. The change
2671 catches this error and just continues.
2673 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2675 2004-04-25 Paul D. Smith <psmith@gnu.org>
2677 * commands.c (set_file_variables): Set $< properly in the face of
2678 order-only prerequisites.
2679 Patch from Boris Kolpackov <boris@kolpackov.net>
2681 2004-04-21 Bob Byrnes <byrnes@curl.com>
2683 * main.c (main): Notice failures to remake makefiles.
2685 2004-03-28 Paul D. Smith <psmith@gnu.org>
2687 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2689 * job.c: No default shell for RISC OS.
2690 (load_too_high): Hard-code the return to 1.
2691 (construct_command_argv_internal): No sh_chars or sh_cmds.
2692 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2694 2004-03-20 Paul D. Smith <psmith@gnu.org>
2696 * variable.c (do_variable_definition): Don't append from the
2697 global set if a previous non-appending target-specific variable
2698 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2701 * expand.c (reference_variable): Don't give up on variables with
2702 no value that have the target-specific append flag set: they might
2703 have a value after all. Reported by Oliver Schmidt
2704 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2705 <nikulin@dx1cmd.inp.nsk.su>.
2707 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2708 refer to absolute pathnames in directories that don't exist: some
2709 portion of the makefile could create those directories before we
2710 match the pattern. Fixes bugs #775 and #108.
2712 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2714 * main.c (main): Free makefile_mtimes if we have any.
2715 * README.W32.template: Update documentation for the current status
2716 of the MS-Windows port.
2717 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2718 environment variable is sometimes already defined which causes the
2720 * main.c (debug_signal_handler): Only define this function if
2721 SIGUSR1 is available.
2723 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2725 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2726 * README.OS2.template: Documentation updates.
2727 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2728 link line for safety.
2729 * maintMakefile (build.sh.in): Remove an extraneous ")".
2730 * job.c (child_execute_job): Close saved FDs.
2731 * job.c (exec_command) [OS/2]: exec_command(): If the command
2732 can't be exec'ed and if the shell is not Unix-sh, then try again
2733 with argv = { "cmd", "/c", ... }. Normally, this code is never
2734 reached for the cmd shell unless the command really doesn't exist.
2735 (construct_command_argv_internal) [OS/2]: The code for cmd
2736 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2737 The CMD builtin commands are case insensitive so use strcasecmp().
2739 2004-03-19 Paul D. Smith <psmith@gnu.org>
2741 * read.c (do_define): Re-order line counter increment so the count
2742 is accurate (we were losing one line per define). Reported by
2743 Dave Yost <Dave@Yost.com>.
2745 2004-03-06 Paul D. Smith <psmith@gnu.org>
2747 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2749 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2750 * misc.c (message,error,fatal): Ditto.
2751 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2752 * config.h.W32.template: Ditto.
2753 * config.h-vms.template: Ditto.
2754 * config.ami.template: Ditto.
2756 2004-03-04 Paul D. Smith <psmith@gnu.org>
2758 * README.template: Add a note about broken /bin/sh on SunOS
2759 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2761 * misc.c (message, error, fatal): Don't use "..." if we're using
2762 varargs. ansi2knr should handle this but it doesn't work: it
2763 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2764 done. On many systems (SunOS for example) va_dcl is a #define.
2765 So, force the use of the non-"..." version on pre-ANSI compilers.
2767 * maintMakefile (sign-dist): Create some rules to help automate
2768 the new GNU ftp upload method.
2770 2004-02-24 Paul D. Smith <psmith@gnu.org>
2772 * config.h.W32.template: Add HAVE_STDARG_H
2773 * config.h-vms.template: Ditto.
2774 * config.ami.template: Ditto.
2776 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2778 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2779 * build_w32.bat: Remove extra "+".
2781 2004-02-23 Paul D. Smith <psmith@gnu.org>
2783 * make.h: Create an UNUSED macro to mark unused parameters.
2784 * (many): Clean up warnings by applying UNUSED, fixing
2785 signed/unsigned incompatibilities, etc.
2787 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2789 * filedef.h: Name the command_state enumeration.
2790 * file.c (set_command_state): Use the enumeration in the function
2793 * configure.in: Explicitly set SET_MAKE to empty, to disable
2794 MAKE=make even when no make already exists. Fix bug #3823.
2796 2004-02-22 Paul D. Smith <psmith@gnu.org>
2798 * maintMakefile: Perl script to clean up all non-CVS files. Use
2799 it on all the subdirectories for the cvs-clean target.
2801 * main.c (decode_switches): Require non-empty strings for all our
2802 string command-line options. Fixes Debian bug # 164165.
2804 * configure.in: Check for stdarg.h and varargs.h.
2805 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2806 for printing messages.
2807 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2812 A number of patches for OS/2 support from Andreas Buening
2813 <andreas.buening@nexgo.de>:
2815 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2816 disable the SIGCHLD handler.
2817 (reap_children) [OS/2]: Remove special handling of job_rfd.
2818 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2819 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2820 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2821 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2822 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2825 2004-02-21 Paul D. Smith <psmith@gnu.org>
2827 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2828 <mail@kristov.de> reports that if process_begin() fails we don't
2829 handle the error condition correctly in all cases.
2830 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2831 to have a newline on the message.
2833 * job.c (construct_command_argv_internal): Add "test" to UNIX
2834 sh_cmds[]. Fixes Savannah bug # 7606.
2836 2004-02-04 Paul D. Smith <psmith@gnu.org>
2838 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2839 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2840 Hartmut Becker <Hartmut.Becker@hp.com>.
2842 2004-01-21 Paul D. Smith <psmith@gnu.org>
2844 * job.c (load_too_high): Implement an algorithm to control the
2845 "thundering herd" problem when using -l to control job creation
2846 via the load average. The system only recomputes the load once a
2847 second but we can start many jobs in a second. To solve this we
2848 keep track of the number of jobs started in the last second and
2849 apply a weight to try to guess what a correct load would be.
2850 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2851 Also fixes bug #4693.
2852 (reap_children): Decrease the job count for this second.
2853 (start_job_command): Increase the job count for this second.
2855 * read.c (conditional_line): Expand the text after ifn?def before
2856 checking to see if it's a single word. Fixes bug #7257.
2858 2004-01-09 Paul D. Smith <psmith@gnu.org>
2860 * file.c (print_file): Recurse to print all targets in
2861 double-colon rules. Fixes bug #4518, reported (with patch) by
2862 Andrew Chatham <chatham@google.com>.
2864 2004-01-07 Paul D. Smith <psmith@gnu.org>
2866 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2867 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2868 AC_FUNC_SETVBUF_REVERSED.
2870 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2871 (MAKE Variable): Fix Savannah bug #4898.
2873 * job.c (construct_command_argv_internal): Add "!" to the list of
2874 shell escape chars. POSIX sh allows it to appear before a
2875 command, to negate the exit code. Fixes bug #6404.
2877 * implicit.c (pattern_search): When matching an implicit rule,
2878 remember which dependencies have the ignore_mtime flag set.
2879 Original fix provided in Savannah patch #2349, by Benoit
2880 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2882 2003-11-22 Paul D. Smith <psmith@gnu.org>
2884 * README.W32.template (Outputs): Clarification on -j with
2885 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2888 2003-11-02 Paul D. Smith <psmith@gnu.org>
2890 * function.c (func_if): Strip all the trailing whitespace from the
2891 condition, then don't expand it. Fixed bug # 5798.
2893 * expand.c (recursively_expand_for_file): If we're expanding a
2894 variable with no file context, then use the variable's context.
2897 2003-10-21 Paul D. Smith <psmith@gnu.org>
2899 * main.c (log_working_directory): Add newlines to printf()s.
2901 * README.cvs: Add a note to ignore warnings during autoreconf.
2903 * maintMakefile (po_repo): Set a new URL for PO file updates.
2904 (get-config/config.guess get-config/config.sub): Get these files
2905 from the Savannah config project instead of ftp.gnu.org.
2907 2003-10-05 Paul Eggert <eggert@twinsun.com>
2909 * main.c (main): Avoid potential subscript error if environ has
2912 2003-08-22 Paul D. Smith <psmith@gnu.org>
2914 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2915 systems which don't yet implement the C89 standard :-/.
2917 2003-07-18 Paul D. Smith <psmith@gnu.org>
2919 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2920 [WINDOWS32]: Initialize hash.
2922 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2924 * dir.c (read_dirstream): Provide a workaround for broken versions of
2925 the MinGW dirent structure.
2927 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2929 * w32/include/dirent.h: Add __MINGW32__ filter.
2931 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2933 * make.h: Add global declaration of *make_host.
2934 * main.c (print_usage): Remove local declaration of *make_host.
2935 (print_version): Display "This program built for ..." after Copyright
2938 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2940 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2941 execution of "makeinfo --html make.texi".
2943 2003-04-30 Paul D. Smith <psmith@gnu.org>
2945 * build.template: Make some changes to maybe allow this script to
2946 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2948 * README.OS2.template: New file for OS/2 support. Original
2949 contributed by Andreas Buening.
2950 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2953 2003-04-19 Paul D. Smith <psmith@gnu.org>
2955 Fix bug #1405: allow a target to match multiple pattern-specific
2958 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2959 variable.c, where they've always belonged.
2960 * rule.h: Move the prototypes and struct pattern_var as well.
2961 * variable.c (initialize_file_variables): Invoke
2962 lookup_pattern_var() in a loop, until no more matches are found.
2963 If a match is found, create a new variable set for the target's
2964 pattern variables. Then merge the contents of each matching
2965 pattern variable set into the target's pattern variable set.
2966 (lookup_pattern_var): Change this function to be usable
2967 in a loop. It takes a starting position: if NULL, start at the
2968 beginning; if non-NULL, start with the pattern variable after that
2969 position, and return the next matching pattern.
2970 (create_pattern_var): Create a unique instance of
2971 pattern-specific variables for every definition in the makefile.
2972 Don't combine the same pattern together. This allows us to
2973 process the variable handling properly even when the same pattern
2974 is used multiple times.
2975 (parse_variable_definition): New function: break out the parsing
2976 of a variable definition line from try_variable_definition.
2977 (try_variable_definition): Call parse_variable_definition to
2979 (print_variable_data_base): Print out pattern-specific variables.
2980 * variable.h (struct variable): Remember when a variable is
2981 conditional. Also remember its flavor.
2982 (struct pattern_var): Instead of keeping a variable set, we just
2983 keep a single variable for each pattern.
2984 * read.c (record_target_var): Each pattern variable contains only a
2985 single variable, not a set, so create it properly.
2986 * doc/make.texi (Pattern-specific): Document the new behavior.
2988 2003-04-17 Paul D. Smith <psmith@gnu.org>
2990 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2991 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2992 file/directory naming rules for VMS so I can't tell whether this
2995 2003-04-09 Paul D. Smith <psmith@gnu.org>
2997 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2998 DOS-style pathnames: backslash separators and drive specifiers.
3000 2003-03-28 Paul D. Smith <psmith@gnu.org>
3002 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3003 the intermediate flag on all targets. Fixes bug #2515.
3005 2003-03-24 Paul D. Smith <psmith@gnu.org>
3007 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3008 Upgrade to autoconf 2.57 and automake 1.7.3.
3010 * job.c: More OS/2 changes from Andreas Buening.
3012 * file.c (print_file): Fix variable initialization.
3015 * remake.c (notice_finished_file):
3017 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3018 some calls (like readdir()) return NULL in valid situations
3019 without resetting errno. Fixes bug #2846.
3021 2003-02-25 Paul D. Smith <psmith@gnu.org>
3023 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3025 * job.c (_is_unixy_shell) [OS/2]: New function.
3026 Set default shell to /bin/sh.
3027 (reap_children): Close the job_rfd pipe here since we don't use a
3029 (set_child_handler_action_flags): define this to empty on OS/2.
3030 (start_job_command): Close the jobserver pipe and use
3031 child_execute_job() instead of fork/exec.
3032 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3033 rather than exec'ing, then reconfigure stdin/stdout.
3034 (exec_command): Rewrite to use spawn instead of exec. Return the
3037 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3038 in DOS. Handle the TEMP environment variable as in DOS. Don't
3039 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3040 use -j in DOS mode. Use child_execute_job() instead of
3043 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3046 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3047 prototypes that return values.
3049 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3051 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3052 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3054 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3057 2003-02-24 Paul D. Smith <psmith@gnu.org>
3059 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3060 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3061 (child_execute_job) [VMS]: Handle error status properly.
3062 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3064 * function.c (func_shell): Use EINTRLOOP() while reading from the
3065 subshell pipe (Fixes bug #2502).
3066 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3068 * main.c (main): Ditto.
3070 2003-01-30 Paul D. Smith <psmith@gnu.org>
3072 * read.c (eval): eval() was not fully reentrant, because the
3073 collapsed buffer was static. Change it to be an automatic
3074 variable so that eval() can be invoked recursively.
3076 (eval): Apply patch # 1022: fix memory reference error on long
3077 target-specific variable lines.
3078 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3080 * function.c (check_numeric): Combine the is_numeric() function
3081 into this function, since it's only called from one place.
3082 Constify this function. Have it print the incorrect string in the
3083 error message. Fixes bug #2407.
3084 (strip_whitespace): Constify.
3085 (func_if): Constify.
3086 * expand.c (expand_argument): Constify.
3088 2003-01-29 Paul D. Smith <psmith@gnu.org>
3090 Fix bug # 2169, also reported by other people on various systems.
3092 * make.h: Some systems, such as Solaris and PTX, do not fully
3093 implement POSIX-compliant SA_RESTART functionality; important
3094 system calls like stat() and readdir() can still fail with EINTR
3095 even if SA_RESTART has been set on the signal handler. So,
3096 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3097 EINTR for system calls which return -1 or 0 (NULL), respectively,
3099 Also, remove the old atomic_stat()/atomic_readdir() and
3100 HAVE_BROKEN_RESTART handling.
3102 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3104 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3105 * remake.c (touch_file): Ditto.
3107 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3108 * read.c (construct_include_path): Ditto.
3109 * remake.c (name_mtime): Ditto.
3110 * vpath.c (selective_vpath_search): Ditto.
3111 * dir.c (find_directory): Ditto.
3112 (local_stat): Ditto.
3113 (find_directory): Use ENULLLOOP() to wrap opendir().
3114 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3116 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3117 atomic_readdir() handling.
3119 2003-01-22 Paul D. Smith <psmith@gnu.org>
3121 * function.c (func_call): Fix Bug #1744. If we're inside a
3122 recursive invocation of $(call ...), mask any of the outer
3123 invocation's arguments that aren't used by this one, so that this
3124 invocation doesn't "inherit" them accidentally.
3126 2002-12-05 Paul D. Smith <psmith@gnu.org>
3128 * function.c (subst_expand): Valery Khamenia reported a
3129 pathological performance hit when doing substitutions on very
3130 large values with lots of words: turns out we were invoking
3131 strlen() a ridiculous number of times. Instead of having each
3132 call to sindex() call strlen() again, keep track of how much of
3133 the text we've seen and pass the length to sindex().
3135 2002-11-19 Paul D. Smith <psmith@gnu.org>
3137 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3140 2002-11-16 Paul D. Smith <psmith@gnu.org>
3142 * NMakefile.template (OBJS): Add hash.c object file.
3143 * SMakefile.template (srcs): Ditto.
3144 * Makefile.ami (objs): Ditto.
3145 * build_w32.bat: Ditto.
3147 * Makefile.DOS.template: Remove extra dependencies.
3149 2002-10-25 Paul D. Smith <psmith@gnu.org>
3151 * expand.c (install_variable_buffer): New function. Install a new
3152 variable_buffer context and return the previous one.
3153 (restore_variable_buffer): New function. Free the current
3154 variable_buffer context and put a previously saved one back.
3155 * variable.h: Prototypes for {install,restore}_variable_buffer.
3156 * function.c (func_eval): Push a new variable_buffer context
3157 before we eval, then restore the old one when we're done.
3160 * read.c (install_conditionals): New function. Install a new
3161 conditional context and return the previous one.
3162 (restore_conditionals): New function. Free the current
3163 conditional context and put a previously saved one back.
3164 (eval): Use the {install,restore}_conditionals for "include"
3166 (eval_buffer): Use {install,restore}_conditionals to preserve the
3167 present conditional state before we evaluate the buffer.
3170 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3172 (Recursion): Add a variable index entry for CURDIR.
3174 * README.cvs: Update to appropriate versions.
3175 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3176 don't need to copy loadavg.c: automake is smart enough to create
3177 it for me. Still have a bug in automake related to ansi2knr tho.
3179 2002-10-14 Paul D. Smith <psmith@gnu.org>
3181 * remake.c (notice_finished_file): Only touch targets if they have
3182 at least one command (as per POSIX). Resolve Bug #1418.
3184 * *.c: Convert to using ANSI C-style function definitions.
3185 * Makefile.am: Enable the ansi2knr feature of automake.
3186 * configure.in: ditto.
3188 2002-10-13 Paul D. Smith <psmith@gnu.org>
3190 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3191 for automatic variable values like $^, etc. In the case of very
3192 large lists of prerequisites this causes problems. Instead reuse
3193 a static buffer (resizeable) for each variable.
3195 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3196 target-specific variable definitions. Check for it and set an
3198 (record_target_var): Set the export field to v_export if the
3199 "exported" flag is set.
3200 * doc/make.texi (Target-specific): Document the ability to use
3203 * doc/make.texi: Change the name of the section on automatic
3204 variables from "Automatic" to "Automatic Variables". Added text
3205 clarifying the scope of automatic variables.
3207 2002-10-04 Paul D. Smith <psmith@gnu.org>
3209 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3211 (record_files): Ditto.
3213 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3214 the search for the '=' to only within the enclosing parens.
3216 2002-10-03 Paul D. Smith <psmith@gnu.org>
3218 Version 3.80 released.
3220 * dir.c: Change hash functions to use K&R function definition style.
3221 * function.c: Ditto.
3223 * variable.c: Ditto.
3225 Update to automake 1.7.
3227 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3228 (pdf): Remove this target as automake now provides one.
3230 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3232 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3234 * makefile.com: Updates for GNU make 3.80.
3235 * makefile.vms: Ditto.
3237 2002-09-23 Paul D. Smith <psmith@gnu.org>
3239 * read.c (enum make_word_type): Remove w_comment.
3240 (get_next_mword): Don't treat comment characters as special; where
3241 this function is used we will never see a comment (it's stripped
3242 before we get here) and treating comments specially means that
3243 targets like "foo\#bar" aren't handled properly.
3245 2002-09-18 Paul D. Smith <psmith@gnu.org>
3247 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3249 * read.c (eval): Expansion of arguments to export/unexport was
3250 ignoring all arguments after the first one. Change the algorithm
3251 to expand the whole line once, then parse the results.
3253 2002-09-17 Paul D. Smith <psmith@gnu.org>
3255 Fix Bug #940 (plus another bug I found while looking at this):
3257 * read.c (record_target_var): enter_file() will add a new entry if
3258 it's a double-colon target: we don't want to do that in this
3259 situation. Invoke lookup_file() and only enter_file() if it does
3260 not already exist. If the file we get back is a double-colon then
3261 add this variable to the "root" double-colon target.
3263 * variable.c (initialize_file_variables): If this file is a
3264 double-colon target but is not the "root" target, then initialize
3265 the root and make the root's variable list the parent of our
3268 2002-09-13 Paul D. Smith <psmith@gnu.org>
3270 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3272 * hash.c (round_up_2): Get rid of a warning.
3274 2002-09-12 Paul D. Smith <psmith@gnu.org>
3276 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3277 so it doesn't complain about getloadavg.c.
3279 * commands.c (set_file_variables): Make sure we always alloca() at
3280 least 1 character for the value of $? (for '\0').
3282 2002-09-11 Paul D. Smith <psmith@gnu.org>
3284 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3285 macro to use RESULT instead of the incorrect _RESULT_.
3287 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3288 and atomic_readdir(). We need to #include dirent.h to get this to
3290 * misc.c (atomic_readdir): Fix typos.
3292 2002-09-10 Paul D. Smith <psmith@gnu.org>
3294 * read.c (eval): Expand variable lists given to export and
3295 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3296 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3298 * doc/make.texi (Variables/Recursion): Document this.
3299 (Conditional Syntax): And here.
3301 2002-09-09 Paul D. Smith <psmith@gnu.org>
3303 * configure.in: Check for memmove().
3305 2002-09-07 Paul D. Smith <psmith@gnu.org>
3307 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3308 Michael Sterrett <msterret@coat.com> reports that while it has
3309 SA_RESTART, it does not work properly.
3311 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3312 that invokes stat() and loops to do it again if it returns EINTR.
3313 (atomic_readdir): Ditto, with readdir().
3315 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3316 and readdir() to atomic_stat() and atomic_readdir().
3318 2002-09-04 Paul D. Smith <psmith@gnu.org>
3320 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3321 reports that GNU make sometimes doesn't recognize that targets can
3322 be made, when directories can be created as prerequisites. He
3323 reports that changing the order of predicates in the DEP->changed
3324 flag test so that lookup_file() is always performed, solves this
3327 2002-08-08 Paul D. Smith <psmith@gnu.org>
3329 * configure.in: Require a newer version of gettext.
3331 * misc.c (perror_with_name): Translate the format string (for
3332 right-to-left language support).
3333 (pfatal_with_name): Ditto.
3335 * main.c: Create a static array of strings to store the usage
3336 text. This is done to facilitate translations.
3337 (struct command_switch): Remove argdesc and description fields.
3338 (switches): Remove values for obsolete fields.
3339 (print_usage): Print each element of the usage array.
3341 * hash.c: Change function definitions to be K&R style.
3343 2002-08-02 Paul D. Smith <psmith@gnu.org>
3345 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3346 this one because it's too hard to get right. We'll look at it for
3348 * main.c (main): Don't create the .TARGETS variable.
3349 * variable.c (handle_special_var): Don't handle .TARGETS.
3351 2002-08-01 Paul D. Smith <psmith@gnu.org>
3353 * main.c (switches): Add a new option, -B (--always-make). If
3354 specified, make will rebuild all targets that it encounters even
3355 if they don't appear to be out of date.
3356 (always_make_flag): New flag.
3357 * make.h: Extern always_make_flag.
3358 * remake.c (update_file_1): Check always_make_flag; if it's set we
3359 will always rebuild any target we can, even if none of its
3360 prerequisites are newer.
3363 * doc/make.texi (Shell Function): Make it clear that make
3364 variables marked as "export" are not passed to instances of the
3367 Add new introspection variable .VARIABLES and .TARGETS.
3369 * variable.c (handle_special_var): New function. If the variable
3370 reference passed in is "special" (.VARIABLES or .TARGETS),
3371 calculate the new value if necessary. .VARIABLES is handled here:
3372 walk through the hash of defined variables and construct a value
3373 which is a list of the names. .TARGETS is handled by
3374 build_target_list().
3375 (lookup_variable): Invoke handle_special_var().
3376 * file.c (build_target_list): Walk through the hask of known files
3377 and construct a list of the names of all the ones marked as
3379 * main.c (main): Initialize them to empty (and as simple variables).
3380 * doc/make.texi (Special Variables): Document them.
3381 * NEWS: Mention them.
3383 * variable.h (struct variable): Add a new flag "exportable" which
3384 is true if the variable name is valid for export.
3385 * variable.c (define_variable_in_set): Set "exportable" when a new
3386 variable is defined.
3387 (target_environment): Use the "exportable" flag instead of
3388 re-checking the name here... an efficiency improvement.
3390 2002-07-31 Paul D. Smith <psmith@gnu.org>
3392 * config.h-vms.template: Updates to build on VMS. Thanks to
3393 Brian_Benning@aksteel.com for helping verify the build.
3394 * makefile.com: Build the new hash.c file.
3395 * hash.h: Use strcpmi(), not stricmp(), in the
3396 HAVE_CASE_INSENSITIVE_FS case.
3398 2002-07-30 Paul D. Smith <psmith@gnu.org>
3400 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3401 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3402 Reported by <Brian_Benning@aksteel.com>.
3404 2002-07-10 Paul D. Smith <psmith@gnu.org>
3406 * variable.c (pop_variable_scope): Remove variable made unused by
3407 new hash infrastructure.
3408 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3409 comparisons as well as name comparisons.
3410 * variable.h: Add a prototype for new hash_init_function_table().
3411 * file.c (lookup_file): Remove variables made unused by new hash
3413 * dir.c (directory_contents_hash_2): Missing return of hash value.
3414 (dir_contents_file_exists_p): Remove variables made unused by new
3415 hash infrastructure.
3418 Installed Greg McGary's integration of the hash functions from the
3419 GNU id-utils package:
3421 2002-07-10 Greg McGary <greg@mcgary.org>
3423 * scripts/functions/filter-out: Add literals to to the
3424 pattern space in order to add complexity, and trigger
3425 use of an internal hash table. Fix documentation strings.
3426 * scripts/targets/INTERMEDIATE: Reverse order of files
3427 passed to expected `rm' command.
3429 2002-07-10 Greg McGary <greg@mcgary.org>

3506 variable_hash_cmp): New functions.

3521 2002-07-10 Paul D. Smith <psmith@gnu.org>
3523 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3524 prerequisite list. A real SysV make will expand the entire
3525 prerequisites list _twice_: we don't do that as it's a big
3526 backward-compatibility problem. We only replace those specific
3529 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3530 references left in the list of prerequisites. Check for .POSIX as
3531 we record targets, so we can disable non-POSIX behavior while
3532 reading makefiles as well as running them.
3533 (eval): Check the prerequisite list to see if we have anything
3534 that looks like a SysV prerequisite variable reference.
3536 2002-07-09 Paul D. Smith <psmith@gnu.org>
3538 * doc/make.texi (Prerequisite Types): Add a new section describing
3539 order-only prerequisites.
3541 * read.c (uniquize_deps): If we have the same file as both a
3542 normal and order-only prereq, get rid of the order-only prereq,
3543 since the normal one supersedes it.
3545 2002-07-08 Paul D. Smith <psmith@gnu.org>
3547 * AUTHORS: Added Greg McGary to the AUTHORS file.
3548 * NEWS: Blurbed order-only prerequisites.
3549 * file.c (print_file): Show order-only deps properly when printing
3552 * maintMakefile: Add "update" targets for wget'ing the latest
3553 versions of various external files. Taken from Makefile.maint in
3556 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3557 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3559 2002-07-07 Paul D. Smith <psmith@gnu.org>
3561 * po/*.po: Remove. We'll use wget to retrieve them at release
3564 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3565 rather than a shell you get an exception. Make sure we look up
3566 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3568 * remake.c (notice_finished_file): Fix handling of -t flag.
3569 Patch provided by Henning Makholm <henning@makholm.net>.
3571 * implicit.c (pattern_search): Some systems apparently run short
3572 of stack space, and using alloca() in this function caused an
3573 overrun. I modified it to use xmalloc() on the two variables
3574 which seemed like they might get large. Fixes Bug #476.
3576 * main.c (print_version): Update copyright notice to conform with
3578 (print_usage): Update help output.
3580 * function.c (func_eval): Create a new make function, $(eval
3581 ...). Expand the arguments, put them into a buffer, then invoke
3582 eval_buffer() on the resulting string.
3583 (func_quote): Create a new function, $(quote VARNAME). Inserts
3584 the value of the variable VARNAME without expanding it any
3587 * read.c (struct ebuffer): Change the linebuffer structure to an
3588 "eval buffer", which can be either a file or a buffer.
3589 (eval_makefile): Move the code in the old read_makefile() which
3590 located a makefile into here: create a struct ebuffer with that
3591 information. Have it invoke the new function eval() with that
3593 (eval_buffer): Create a new function that creates a struct ebuffer
3594 that holds a string buffer instead of a file. Have it invoke
3595 eval() with that ebuffer.
3596 (eval): New function that contains the guts of the old
3597 read_makefile() function: this function parses makefiles. Obtains
3598 data to parse from the provided ebuffer. Some modifications to
3599 make the flow of the function cleaner and clearer. Still could
3600 use some work here...
3601 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3602 contents of the define/endef variable from the ebuffer.
3603 (readstring): Read the next line from a string-style ebuffer.
3604 (readline): Read the next line from an ebuffer. If it's a string
3605 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3608 * dep.h (eval_buffer): Prototype eval_buffer();
3610 * variable.c (do_variable_definition): Make sure that all
3611 non-target-specific variables are registered in the global set.
3612 If we're invoked from an $(eval ...) we might be inside a $(call
3613 ...) or other function which has pushed a variable scope; we still
3614 want to define our variables from evaluated makefile code in the
3617 2002-07-03 Greg McGary <greg@mcgary.org>
3619 * dep.h (struct dep) [ignore_mtime]: New member.
3620 [changed]: convert to a bitfield.
3621 * implicit.c (pattern_search): Zero ignore_mtime.
3622 * main.c (main, handle_non_switch_argument): Likewise.
3623 * rule.c (convert_suffix_rule): Likewise.
3624 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3625 (read_makefile): Parse '|' in prerequisite list.
3626 (uniquize_deps): Consider ignore_mtime when comparing deps.
3627 * remake.c (update_file_1, check_dep): Don't force remake for
3628 dependencies that have d->ignore_mtime.
3629 * commands.c (FILE_LIST_SEPARATOR): New constant.
3630 (set_file_variables): Don't include a
3631 prerequisite in $+, $^ or $? if d->ignore_mtime.
3634 2002-06-18 Paul D. Smith <psmith@gnu.org>
3636 * make.texinfo: Updates for next revision. New date/rev/etc.
3637 Recreate all Info menus. Change license on the manual to the GNU
3638 Free Documentation License. A number of typos.
3639 (Variables Simplify): Don't use "-" before it's defined.
3640 (Automatic Prerequisites): Rewrite the target example to work
3641 properly if the compile fails. Remove incorrect comments about
3642 how "set -e" behaves.
3643 (Text Functions): Move the "word", "wordlist", "words", and
3644 "firstword" functions here, from "File Name Functions".
3645 * make-stds.texi: Update from latest GNU version.
3646 * fdl.texi: (created) Import the latest GNU version.
3648 2002-06-06 Paul D. Smith <psmith@gnu.org>
3650 * variable.c (do_variable_definition): New function: extract the
3651 part of try_variable_definition() that actually sets the value
3652 into a separate function.
3653 (try_variable_definition): Call do_variable_definition() after
3654 parsing the variable definition string.
3655 (define_variable_in_set): Make the name argument const.
3657 * variable.h (enum variable_flavor): Make public.
3658 (do_variable_definition): Create prototype.
3660 * read.c (read_all_makefiles): Create a new built-in variable,
3662 (read_makefile): Add each makefile read in to this variable value.
3664 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3666 * Makefile.DOS.template: Tweak according to changes in the
3667 distribution. Add back the dependencies of *.o files.
3669 * configh.dos.template: Synchronize with config.h.in.
3671 2002-05-09 Paul D. Smith <psmith@gnu.org>
3673 * file.c (file_timestamp_now): Use K&R function declaration.
3675 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3676 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3677 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3678 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3679 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3680 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3681 nlist.n_name is a pointer rather than an array.
3683 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3684 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3685 * configure.in: Use it instead of the old version.
3687 * main.c (main): Prefer setvbuf() to setlinebuf().
3689 2002-05-08 Paul D. Smith <psmith@gnu.org>
3691 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3692 (loadavg_LDADD): Ditto.
3694 2002-04-29 Paul D. Smith <psmith@gnu.org>
3696 * expand.c (recursively_expand_for_file): Rename
3697 recursively_expand() to recursively_expand_for_file() and provide
3698 an extra argument, struct file. If the argument is provided, set
3699 the variable scope to that of the file before expanding.
3700 * variable.h (recursively_expand): Make this a macro that invokes
3701 recursively_expand_for_file() with a NULL file pointer.
3702 * variable.c (target_environment): Call the renamed function and
3703 provide the current file context.
3704 Fixes Debian bug #144306.
3706 2002-04-28 Paul D. Smith <psmith@gnu.org>
3708 Allow $(call ...) user-defined variables to be self-referencing
3709 without throwing an error. Allows implementation of transitive
3710 closures, among other possibly useful things.
3711 Requested by: Philip Guenther <guenther@sendmail.com>
3713 * variable.h (struct variable): Add a new field: exp_count, and
3714 new macros to hold its size and maximum value.
3715 (warn_undefined): Make this a macro.
3716 * variable.c (define_variable_in_set): Initialize it.
3717 * expand.c (recursively_expand): If we detect recursive expansion
3718 of a variable, check the exp_count field. If it's greater than 0
3719 allow the recursion and decrement the count.
3720 (warn_undefined): Remove this (now a macro in variable.h).
3721 * function.c (func_call): Before we expand the user-defined
3722 function, modify its exp_count field to contain the maximum
3723 number of recursive calls we'll allow. After the call, reset it
3726 2002-04-21 Paul D. Smith <psmith@gnu.org>
3728 Modified to use latest autoconf (2.53), automake (1.6.1), and
3729 gettext (0.11.1). We're using gettext's new "external" support,
3730 to avoid including libintl source with GNU make.
3732 * README.cvs: New file. Explain how to build GNU make from CVS.
3734 * configure.in: Modify checking for the system glob library.
3735 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3736 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3737 etc. will manage it correctly). Set an automake conditional
3738 USE_LOCAL_GLOB to decide whether to compile the glob library.
3740 * getloadavg.c (main): Include make.h in the "TEST" program to
3743 * Makefile.am: Remove special rules for loadavg. Replace them
3744 with Automake capabilities for building extra programs.
3746 * signame.c: This file does nothing if the system provide
3747 strsignal(). If not, it implements strsignal(). If the system
3748 doesn't define sys_siglist, then we make our own; otherwise we use
3750 * signame.h: Removed.
3752 * main.c (main): No need to invoke signame_init(). Update copyright.
3754 * ABOUT-NLS: Removed.
3755 * gettext.c: Removed.
3756 * gettext.h: Get a simplified copy from the gettext package.
3758 * i18n/*.po: Moved to po/.
3761 * config/*: Created. Contains package configuration helper files.
3762 * config.guess, config.sub: Moved to config directory.
3764 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3765 Rework to use new-style autoconf features. Use the "external"
3766 mode for gettext. Make the build.sh config file conditional on
3767 whether build.sh.in exists, to avoid autoconf errors.
3768 * acinclude.m4: Removed almost all macros as being obsolete.
3769 Rewrote remaining macros to use AC_DEFINE.
3770 * acconfig.h: Removed.
3772 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3773 conditional to handle customs support. Remove special handling
3776 2002-04-20 Paul D. Smith <psmith@gnu.org>
3778 * function.c (func_call): Don't mark the argument variables $1,
3779 etc. as recursive. They've already been fully expanded so
3780 there's no need to do it again, and doing so strips escaped $'s.
3781 Reported by Sebastian Glita <glseba@yahoo.com>.
3783 * remake.c (notice_finished_file): Walk through double-colon
3784 entries via the prev field, not the next field!
3785 Reported by Greg McGary <greg@mcgary.org>.
3787 * main.c (main): If the user specifies -q and asks for a specific
3788 target which is a makefile, we got an assert. In that case it
3789 turns out we should continue normally instead.
3791 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3793 * i18n/he.po: Installed a new translation.
3795 2002-01-07 Paul D. Smith <psmith@gnu.org>
3797 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3799 2001-12-04 Paul D. Smith <psmith@gnu.org>
3801 * i18n/ja.po: Installed an updated translation.
3803 2001-09-06 Paul Eggert <eggert@twinsun.com>
3805 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3806 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3808 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3810 (main): Get rid of any avoidable limit on stack size.
3812 2001-09-04 Paul D. Smith <psmith@gnu.org>
3814 * i18n/da.po: Installed an updated translation.
3816 2001-08-03 Paul D. Smith <psmith@gnu.org>
3818 * i18n/fr.po: Installed an updated translation.
3819 Resolves Debian bug #106720.
3821 2001-06-13 Paul D. Smith <psmith@gnu.org>
3823 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3826 2001-06-11 Paul D. Smith <psmith@gnu.org>
3828 * i18n/ko.po: Installed a new translation.
3830 2001-05-06 Paul D. Smith <psmith@gnu.org>
3832 Modify the EINTR handling.
3834 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3835 the way in which we manage the file descriptor/signal handler race
3836 trap to be more efficient.
3838 2001-05-06 Paul Eggert <eggert@twinsun.com>
3840 Restart almost all system calls that are interrupted, instead
3841 of worrying about EINTR. The lone exception is the read() for
3844 * configure.in (HAVE_SA_RESTART): New macro.
3845 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3846 * main.c (main): Use SA_RESTART instead of the old,
3847 nonstandard SA_INTERRUPT.
3849 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3850 * main.c (bsd_signal): New function or macro,
3851 if the implementation doesn't supply it.
3852 (The bsd_signal function will be in POSIX 1003.1-200x.)
3853 (HANDLESIG): Remove.
3854 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3856 * make.h (EINTR_SET): Remove.
3857 (SA_RESTART): New macro.
3859 * arscan.c (ar_member_touch): Don't worry about EINTR.
3860 * function.c (func_shell): Likewise.
3861 * job.c (reap_children, free_child, new_job): Likewise.
3862 * main.c (main): Likewise.
3863 * remake.c (touch_file, name_mtime): Likewise.
3865 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3866 if fstat failed with errno!=EINTR, the error was ignored.
3868 * job.c (set_child_handler_action_flags): New function.
3869 (new_job): Use it to temporarily clear the SIGCHLD action flags
3870 while reading the token.
3872 2001-05-02 Paul D. Smith <psmith@gnu.org>
3874 * job.c (start_job_command): Don't add define/endef per-line flags
3875 to the top-level flags setting.
3877 2001-04-03 Paul D. Smith <psmith@gnu.org>
3879 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3880 bit on error, so check for odd return values, not non-0 return
3882 (VMS_get_member_info): Calculate the timezone differences correctly.
3883 Reported by John Fowler <jfowler@nyx.net>.
3886 2001-03-14 Paul D. Smith <psmith@gnu.org>
3888 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3889 value before invoking define_variable().
3890 Reported by John Fowler <jfowler@nyx.net>.
3892 2001-02-07 Paul D. Smith <psmith@gnu.org>
3894 * read.c (record_target_var): If we reset the variable due to a
3895 command-line variable setting overriding it, turn off the "append"
3898 2001-01-17 Paul D. Smith <psmith@gnu.org>
3900 * variable.c (lookup_variable) [VMS]: When getting values from the
3901 environment, allocate enough space for the _value_ plus escapes,
3902 not enough space for the name plus escapes :-/.
3903 Reported by John Fowler <jfowler@nyx.net>.
3905 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3906 warnings that make generates, so it doesn't look like an error.
3907 Reported by Karl Berry <karl@gnu.org>.
3910 Fix for PR/2020: Rework appended target-specific variables. I'm
3911 fairly confident this algorithm is finally correct.
3913 * expand.c (allocated_variable_append): Rewrite. Instead of
3914 expanding each appended variable then adding all the expanded
3915 strings together, we append all the unexpanded values going up
3916 through the variable set contexts, then expand the final result.
3917 This behaves just like non-target-specific appended variable
3918 values, while the old way didn't in various corner cases.
3919 (variable_append): New function: recursively append the unexpanded
3920 value of a variable, walking from the outermost variable scope to
3922 * variable.c (lookup_variable): Remove the code that looked up the
3923 variable set list if the found variable was "append". We don't
3925 (lookup_variable_in_set): Make this non-static so we can use it
3927 (try_variable_definition): Use lookup_variable_in_set() rather
3928 than faking out current_variable_set_list by hand (cleanup).
3929 * variable.h: Add a prototype for the now non-static
3930 lookup_variable_in_set().
3932 2000-11-17 Paul D. Smith <psmith@gnu.org>
3934 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3935 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3936 before throwing a fit.
3938 2000-11-17 Paul D. Smith <psmith@gnu.org>
3940 * read.c (readline): CRLF calculations had a hole, if you hit the
3941 buffer grow scenario just right. Reworked the algorithm to avoid
3942 the need for len or lastlen at all. Problem description with
3943 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3945 2000-10-24 Paul D. Smith <psmith@gnu.org>
3947 * gettext.c (SWAP): Declare this with the prototype, otherwise
3948 some systems don't work (non-32-bit? Reported for Cray T3E).
3949 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3951 2000-10-05 Paul D. Smith <psmith@gnu.org>
3953 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3954 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3956 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3958 2000-09-22 Paul D. Smith <psmith@gnu.org>
3960 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3961 parts of the real gettext.h here, and we expect to really include
3962 the real gettext.h later. If we keep this #define, it's ignored.
3964 2000-09-21 Paul D. Smith <psmith@gnu.org>
3966 * main.c (log_working_directory): Rework the text to use complete
3967 sentences, to make life simpler for the translators.
3969 2000-08-29 Paul D. Smith <psmith@gnu.org>
3971 * file.c (remove_intermediates): Print a debug message before we
3972 remove intermediate files, so the user (if she uses -d) knows
3975 2000-08-21 Paul D. Smith <psmith@gnu.org>
3977 * variable.c (try_variable_definition): Change how we handle
3978 target-specific append variable defns: instead of just setting the
3979 value, expand it as an append _but_ only within the current
3980 target's context. Otherwise we lose all but the last value if the
3981 variable is appended more than once within the current target
3982 context. Fixes PR/1831.
3984 2000-08-16 Paul D. Smith <psmith@gnu.org>
3986 * function.c (func_shell): Nul-terminate the buffer before
3987 printing an exec error message (just in case it's not!).
3988 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3990 2000-07-25 Paul D. Smith <psmith@gnu.org>
3992 * job.c (construct_command_argv_internal): Add "~" to the list of
3993 sh_chars[] which disallow optimizing out the shell call.
3995 2000-07-23 Paul Eggert <eggert@twinsun.com>
3997 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3998 supersedes --disable-nsec-timestamps.
3999 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4000 * README: Remove --disable-nsec-timestamps.
4002 * filedef.h (struct file.low_resolution_time): New member.
4003 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4004 * remake.c (update_file_1):
4005 Avoid spurious rebuilds due to low resolution time stamps,
4006 generalizing the earlier code that applied only to archive members.
4007 (f_mtime): Archive members always have low resolution time stamps.
4009 * configure.in: Remove --disable-nsec-timestamps, as this has
4010 been superseded by .LOW_RESOLUTION_TIME.
4012 2000-07-23 Paul Eggert <eggert@twinsun.com>
4014 * configure.in (enable_nsec_timestamps): Renamed from
4015 make_cv_nsec_timestamps, since enable/disable options
4016 shouldn't be cached.
4018 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4019 and Paul Eggert <eggert@twinsun.com>
4021 * file.c (file_timestamp_now):
4022 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4023 so that clock_gettime is not linked unless needed.
4025 * filedef.h (FILE_TIMESTAMP_HI_RES):
4026 Remove definition; "configure" now does this.
4028 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4029 to before high resolution file timestamp check,
4030 since that check now uses uintmax_t.
4031 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4032 high resolution file timestamps.
4033 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4034 so that we don't link in clock_gettime unnecessarily.
4036 2000-07-17 Paul D. Smith <psmith@gnu.org>
4038 * i18n/ja.po: New version of the translation file.
4040 2000-07-07 Paul D. Smith <psmith@gnu.org>
4042 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4043 the offset calculation.
4044 (name_mtime): Replace EINTR test with EINTR_SET macro.
4046 2000-07-07 Paul Eggert <eggert@twinsun.com>
4050 * remake.c (update_file_1):
4051 Avoid spurious rebuilds of archive members due to their
4052 timestamp resolution being only one second.
4053 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4054 the clock's resolution being lower than file timestamps'.
4055 When warning about future timestamps, report only the discrepancy,
4056 not the absolute value of the timestamp and the current time.
4058 * file.c (file_timestamp_now): New arg RESOLUTION.
4059 * filedef.h (file_timestamp_now): Likewise.
4060 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4062 2000-07-05 Paul D. Smith <psmith@gnu.org>
4064 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4065 to listp. Fixes PR/1793.
4067 2000-06-26 Paul Eggert <eggert@twinsun.com>
4069 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4071 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4073 * remake.c (f_mtime): Remove unused var memtime.
4075 2000-06-25 Martin Buchholz <martin@xemacs.org>
4077 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4078 Ran spell-check on make.texinfo.
4080 2000-06-23 Paul D. Smith <psmith@gnu.org>
4082 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4083 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4084 * make.h: Define these macros.
4086 * Version 3.79.1 released.
4088 * configure.in: Add a new option, --disable-nsec-timestamps, to
4089 avoid using sub-second timestamps on systems that support it. It
4090 can lead to problems, e.g. if your makefile relies on "cp -p".
4091 * README.template: Document the issue with "cp -p".
4093 * config.guess, config.sub: Updated.
