552 (Introduction to Pattern Rules): Describe the new pattern rules
555 * NEWS: Add a note about the new behavior.
557 2009-09-27 Paul Smith <psmith@gnu.org>
559 * doc/make.texi (Double-Colon): Mention that pattern rules with
560 double-colons have a different meaning. Savannah bug #27497.
562 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
564 * configh.dos.template: Remove unconditional definition of
565 SYS_SIGLIST_DECLARED.
566 Include <sys/version.h> because ports of GCC 4.3.0 and later no
567 longer include it, so macros like __DJGPP_MINOR__ are no longer
568 defined automatically.
570 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
571 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
572 instead of using the hardcoded ones.
573 (SUBDIRS): doc subdir added.
574 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
575 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
576 create html formated docs. texi2html may not be ported to DOS.
577 (make.info, make.dvi, make.ps, make.html): Make targets depend on
579 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
580 -I switch to look in ./ instead of ./doc.
581 (html): Target depend on html-recursive instead of make_1.html.
582 (make_1.html): Removed.
583 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
584 (all-recursive): Allow for more than one subdir in the build
586 (mostlyclean-recursive, clean-recursive, distclean-recursive)
587 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
588 (tags-recursive): Allow for more than one subdir in the build
590 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
591 targets. Enter into doc/ to produce the targets.
592 (all-am): $(INFO_DEPS) replaced by info.
594 2009-09-26 Paul Smith <psmith@gnu.org>
596 * read.c (record_files): Use free_ns() to free struct nameseq.
599 * rule.c (freerule): Use free_dep_chain().
601 * read.c (record_files): Free FILENAMES chain for implicit rules.
602 (eval): Static pattern targets go into the string cache.
604 * function.c (string_glob): Free NAME in the nameseq chain.
606 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
608 * implicit.c (pattern_search): Terminate early if we haven't
609 found any rules to try (performance improvement).
611 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
613 * implicit.c (pattern_search): Merge three parallel arrays,
614 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
615 of struct TRYRULE. In the old version the latter two arrays
616 had insufficient length.
618 2009-09-24 Paul Smith <psmith@gnu.org>
620 * implicit.c (pattern_search): Add back support for order-only
621 prerequisites for secondary expansion implicit rules, that were
622 accidentally dropped. If we find a "|", enable order-only mode
623 and set IGNORE_MTIME on all deps that are seen afterward.
624 (pattern_search): Fix memory leaks: for intermediate files where
625 we've already set the file variable and pattern variable sets, be
626 sure to either save or free them as appropriate.
628 2009-09-23 Paul Smith <psmith@gnu.org>
630 Rework the way secondary expansion is stored, for efficiency.
631 This changes secondary expansion so that ONLY WHEN we know we have
632 a possibility of needing secondary expansion, do we defer the
633 secondary expansion. This means more parsing the deps but we use
634 a lot less memory (due to the strcache). Also, this fixes
637 * read.c (eval): Don't parse the dep string here anymore.
638 (record_files): Take the dep argument as an unparsed string. If
639 secondary expansion is enabled AND the prereq string has a '$' in
640 it, then set NEED_2ND_EXPANSION and keep the entire string.
641 Otherwise, parse the dep string here to construct the dep list
642 with the names in the strcache.
644 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
645 duplicate the name string (others are in the strcache).
647 * implicit.c: Remove struct idep and free_idep_chain(): unused.
648 (struct patdeps): New structure to store prereq information.
649 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
650 which prerequisites need expansion, and expand only those.
652 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
653 and enter_prereqs(). split_prereqs() takes a fully-expanded string
654 and splits it into a DEP list, handling order-only prereqs.
655 (enter_prereqs): This function enters a list of DEPs into the file
656 database. If there's a stem defined, expand any pattern chars.
657 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
658 set. Use the above functions.
659 (snap_deps): Only perform second expansion on prereqs that need it,
660 as defined by the NEED_2ND_EXPANSION flag.
661 (print_prereqs): New function to print the prereqs
662 (print_file): Call print_prereqs() rather than print inline.
664 * hash.h (STRING_COMPARE): Take advantage of strcache() by
666 (STRING_N_COMPARE): Ditto.
667 (ISTRING_COMPARE): Ditto.
669 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
670 (parse_file_seq): Return void*
671 * read.c (parse_file_seq): Return void*.
672 (eval): Invoke macroized version of parse_file_seq()
673 * default.c (set_default_suffixes): Ditto.
674 * file.c (split_prereqs): Ditto.
675 * function.c (string_glob): Ditto.
676 * main.c (main): Ditto.
677 * rule.c (install_pattern_rule): Ditto.
679 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
681 2009-09-16 Paul Smith <psmith@gnu.org>
683 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
685 * dep.h: Create alloc_dep() / free_dep() macros.
687 * implicit.c (pattern_search): Take advantage of the new
688 parse_file_seq() to add the directory prefix to each prereq.
690 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
691 all. Avoid reversing chains. Support adding prefixes.
692 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
693 cached/non-cached results.
694 (eval): Remove multi_glob() & invoke new parse_file_seq().
695 * rule.c (install_pattern_rule): Ditto.
696 * main.c (main): Ditto.
697 * implicit.c (pattern_search): Ditto.
698 * function.c (string_glob): Ditto.
699 * file.c (parse_prereqs): Ditto.
700 * default.c (set_default_suffixes): Ditto.
702 * variable.c (parse_variable_definition): Don't run off the end of
703 the string if it ends in whitespace (found with valgrind).
705 * commands.c (set_file_variables): Keep space for all targets in
706 $? if -B is given (found with valgrind).
708 2009-09-15 Paul Smith <psmith@gnu.org>
710 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
711 (xcalloc): Add new function.
712 * make.h: New declarations.
714 * ar.c (ar_glob_match): New calling method for concat().
715 * main.c (main): Ditto.
716 (decode_env_switches): Ditto.
717 * read.c (eval_makefile): Ditto.
718 (tilde_expand): Ditto.
719 (parse_file_seq): Ditto.
720 * variable.c (target_environment): Ditto.
721 (sync_Path_environment): Ditto.
723 * ar.c (ar_glob_match): Use xcalloc().
724 * dir.c (file_impossible): Ditto.
725 * file.c (enter_file): Ditto.
726 * job.c (new_job): Ditto.
727 * read.c (parse_file_seq): Ditto.
728 * vmsfunctions.c (opendir): Ditto.
730 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
732 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
733 inside the loop that looks up environment for PATH.
735 2009-08-31 Eli Zaretskii <eliz@gnu.org>
737 * function.c (windows32_openpipe): Update envp after calling
738 sync_Path_environment.
740 2009-08-02 Paul Smith <psmith@gnu.org>
742 * remake.c (notice_finished_file): Ensure file->cmds is not null
743 before looping through them. Fixes Savannah bug #21824.
745 * doc/make.texi (Wildcard Examples): Clarify when objects is
746 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
747 (Include): Clarify the behavior of -include.
748 Fixes Savannah bug #18963.
750 2009-08-01 Paul Smith <psmith@gnu.org>
752 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
753 etc. come on the command line. Fixes Savannah bug #27093.
755 * expand.c (expand_argument): If the argument is large enough use
756 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
758 * variable.c (do_variable_definition): Avoid using alloca() to
759 hold values, which can be large. Fixes Savannah bug #23960.
761 * job.c (new_job): Use memmove() instead of strcpy() since both
762 pointers are in the same memory block. Fixes Savannah bug #27148.
763 Patch by Petr Machata.
765 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
767 * job.c (construct_command_argv_internal): Add "ulimit" and
768 "unset" to the sh_cmds for Unixy shells.
770 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
772 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
773 that set make_cv_sys_gnu_glob, so they are also correctly set
774 when the cache has been populated before.
776 2009-07-04 Eli Zaretskii <eliz@gnu.org>
778 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
779 exist, as realpath(3) does where it's supported.
781 2006-07-04 Eli Zaretskii <eliz@gnu.org>
783 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
784 (abspath): Support systems that define HAVE_DOS_PATHS (have
785 drive letters in their file names). Use IS_PATHSEP instead of a
786 literal '/' comparison. Fixes Savannah bug #26886.
788 2009-06-14 Paul Smith <psmith@gnu.org>
790 * remake.c (update_file_1): Remember the original file we marked
791 as updating, so we can clear that flag again. If we find a target
792 via vpath, FILE might change.
793 (check_dep): Ditto. Fixes Savannah bug #13529.
794 Patch by Reid Madsen <reid.madsen@tek.com>.
796 2009-06-13 Paul Smith <psmith@gnu.org>
798 * doc/make.texi (MAKEFILES Variable): Be explicit that files
799 included by MAKEFILES cannot give default goals.
800 * read.c (eval): If set_default is not set, pass the no-default-goal
801 value when we read included makefiles. Fixes Savannah bug #13401.
803 * ar.c (ar_name): Ensure that targets with empty parens aren't
804 considered archive member references: archive members must have a
805 non-empty "member" string. Fixes Savannah bug #18435.
807 * function.c (string_glob): Rely on multi_glob() to determine
808 whether files exist or not. Remove call to file_exists_p() which
809 is not always correct. Fixes Savannah bug #21231.
810 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
811 then only files that really exist will be returned.
812 * dep.h: Add new argument to multi_glob().
813 * rule.c (install_pattern_rule): Ditto.
814 * read.c (eval): Ditto.
815 * main.c (main): Ditto.
816 * implicit.c (pattern_search): Ditto.
817 * file.c (parse_prereqs): Ditto.
818 * default.c (set_default_suffixes): Ditto.
820 2009-06-09 Paul Smith <psmith@gnu.org>
822 * commands.c (set_file_variables): If always_make_flag is set,
823 always add the prereq to $?. Fixes Savannah bug #17825.
825 * remake.c (update_file_1): When rebuilding deps of FILE, also try
826 to rebuild the deps of all the also_make targets for that file.
827 Fixes Savannah bug #19108.
829 * implicit.c (pattern_search): Undo test for is_target, added by
830 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
831 Rule Search Algorithm". Fixes Savannah bug #17752.
833 * main.c (clean_jobserver): Clear the jobserver_fds options and
834 set job_slots to the default when we clean up.
835 (define_makeflags): Return the new MAKEFLAGS value.
836 (main): Reset MAKEFLAGS in the environment when we re-exec.
837 Fixes Savannah bug #18124.
839 2009-06-08 Paul Smith <psmith@gnu.org>
841 * read.c (eval): Collapse continuations post-semicolon on target-
842 specific variables. Fixes Savannah bug #17521.
844 2009-06-07 Paul Smith <psmith@gnu.org>
846 * job.c (reap_children): For older systems without waitpid() (are
847 there any of these left?) run wait(2) inside EINTRLOOP to handle
848 EINTR errors. Fixes Savannah bug #16401.
850 * (various): Debug message cleanup. Fixes Savannah bug #16469.
852 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
854 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
855 not the end, to catch second expansion $(eval ...) defining new
856 target/prereq relationships during snap_deps.
857 Fixes Savannah bug #24622.
859 * read.c (record_files): The second-expansion "f->updating" hack
860 was not completely correct: if assumed that the target with
861 commands always had prerequisites; if one didn't then the ordering
862 was messed up. Fixed for now to use f->updating to decide whether
863 to preserve the last element in the deps list... but this whole
864 area of constructing and reversing the deps list is too confusing
865 and needs to be reworked. Fixes Savannah bug #21198.
867 2009-06-06 Paul Smith <psmith@gnu.org>
869 * hash.c (hash_insert): Remove useless test for NULL.
870 Fixes Savannah bug #21823.
872 * make.h: Move SET_STACK_SIZE determination to make.h.
873 * main.c (main): New global variable, STACK_LIMIT, holds the
874 original stack limit when make was started.
875 * job.c (start_job_command): Reset the stack limit, if we changed it.
876 Fixes Savannah bug #22010.
878 * remake.c (check_dep): Only set the target's state to not-started
879 if it's not already running. Found this while testing -j10 builds
880 of glibc: various targets were being rebuilt multiple times.
881 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
884 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
885 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
888 2009-06-04 Paul Smith <psmith@gnu.org>
890 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
892 * maintMakefile: Modify access of config and gnulib Savannah
893 modules to use GIT instead of CVS.
895 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
896 Fixes Savannah bug #24655.
898 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
899 this can happen during some invocations of $(eval ...) for example.
900 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
902 2009-06-02 Paul Smith <psmith@gnu.org>
904 * configure.in: Check for fileno()
905 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
906 for the makefile file so invocations of $(shell ...) don't inherit it.
907 Fixes Savannah bug #24277.
909 2009-06-01 Paul Smith <psmith@gnu.org>
911 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
912 expansion was handled incorrectly. Rework the default goal
913 handling to save the variable only. Remove default_goal_file and
915 * read.c (eval): Check default_goal_var, not default_goal_name.
916 * read.c (record_target_var): Don't check default_goal_file here.
918 2009-05-31 Paul Smith <psmith@gnu.org>
920 * main.c (main): Expand the .DEFAULT_GOAL variable before using
921 it, and if the multi_glob() returns nothing (say it expanded to
922 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
924 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
925 $(and ..) to the reference. Fixes Savannah bug #25694.
927 * make.1: Be clear that some recipes will be executed even with -n.
928 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
930 * doc/make.texi (Override Directive): Make more clear how
931 overrides and appends interact.
932 Elucidates part of Savannah bug #26207.
934 * read.c (record_target_var): Don't reset the origin on
935 target-specific variables; try_variable_definition() will handle
936 this correctly. Fixes Savannah bug #26207.
938 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
939 Fixes Savannah bug #25712.
941 * implicit.c (pattern_search): Keep a pointer to the beginning of
942 the filename and save that instead of the constructed pointer.
943 Fixes Savannah bug #26593.
944 Patch by Mark Seaborn <mrs@mythic-beasts.com>
946 2009-05-30 Paul Smith <psmith@gnu.org>
948 * doc/make.texi (Multi-Line): Add a description of the new abilities
949 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
950 "command sequence" vs. "recipe" syntax.
951 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
952 after a define, to create variables with those flavors.
954 2009-05-25 Paul Smith <psmith@gnu.org>
956 Reworked the parser for variable assignments to allow multiple
957 modifiers, and in any order. Also allows variable and
958 prerequisites to be modifier names ('export', 'private', etc.)
960 * NEWS: Add notes about user-visible changes.
962 * read.c (struct vmodifiers): Remember what modifiers were seen.
963 (parse_var_assignment): New function to parse variable assignments.
964 (eval): Call the new function. Handle variable assignments earlier.
966 * variable.c (parse_variable_definition): Only parse; don't create var.
967 (assign_variable_definition): Call parse, then create the var.
969 2009-05-24 Paul Smith <psmith@gnu.org>
971 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
972 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
974 2009-03-14 Eli Zaretskii <eliz@gnu.org>
976 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
977 Fixes Savannah bug #25412.
979 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
980 prototype for xmalloc.
981 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
982 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
983 Loop over an array of extensions, instead of duplicating the same
984 code inline. Use SearchPath followed by CreateFile, instead of
985 the obsolete OpenFile. Fixes Savannah bug #17277.
986 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
987 to `find_file'. Fixes Savannah bug #25662.
989 2009-03-07 Eli Zaretskii <eliz@gnu.org>
991 * function.c (func_shell): Don't close pipedes[1] if it is -1.
992 Fixes Savannah bug #20495.
994 2009-02-28 Ralf Wildenhues <address@hidden>
996 * doc/make.texi (Instead of Execution): Document interaction of
997 -t with phony targets.
999 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1001 Introduce a new keyword "private" which applies to target-specific
1002 variables and prevents their values from being inherited.
1004 * variable.h (struct variable): Add private_var flag to each variable.
1005 Add a flag to specify which list entry switches to the parent target.
1006 * variable.c (define_variable_in_set): Initialize private_var flag.

1025 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1027 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1030 * w32/subproc/build.bat (GCCBuild): Likewise.
1032 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1034 * job.c (construct_command_argv_internal): Avoid extra backslash
1035 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1038 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1040 * README.W32.template: Remove obsolete text about non-support for
1041 -jN without Unixy shell. Remove obsolete text about not supplying
1042 Visual Studio project files (we do supply them). Modify text to
1043 prefer GCC builds to MSC builds.
1045 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1047 * doc/make.texi (Empty Targets): Fix typo.
1049 2008-03-27 Paul Smith <psmith@gnu.org>
1051 Fix Savannah bug #22379:
1052 * ar.c (ar_glob_match): Zero the allocated structure.
1053 * read.c (parse_file_seq): Ditto.
1055 2008-03-08 Brian Dessent <brian@dessent.net>
1057 * maintMakefile: Update Translation Project location.
1059 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1061 * variable.c (target_environment): Don't use shell_var if its
1062 `value' field is NULL.
1064 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1066 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1068 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1069 (TEXINFOS): Value changed to `doc/make.texi'.
1070 (.SUFFIXES): Use .texi instead of .texinfo.
1071 (make.info, make.dvi): Depend on doc/make.texi.
1072 (.texi.info): New target, instead of ".texinfo.info". Change -I
1073 switch to $(MAKEINFO) to look in doc/. Use --no-split.

1077 switch to $(MAKEINFO) to look in doc/.
1078 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1079 "*.i[0-9][0-9]" (due to --no-split above).

1081 (html, make_1.html): New targets.
1082 (.PHONY): Add "html".
1083 (.SUFFIXES): Add .html.
1085 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1087 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1088 HAVE_DECL_SYS_SIGLIST.
1090 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1091 build does not use child_execute_job.
1093 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1094 export the SHELL environment variable to the child.
1096 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1102 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1105 2007-11-04 Paul Smith <psmith@gnu.org>
1107 * doc/make.texi: Convert references to "commands", "command

1115 * remake.c (f_mtime): Print time difference values between 100 and
1116 ULONG_MAX in fixed-point notation rather than in exponention notation.
1118 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1120 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1121 a more complex value than a simple shell: if it's not a default
1122 shell now then expand it and see if is a default shell then.
1124 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1126 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1127 pathnames, with const strings.
1128 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1133 * make.h: Add a prototype for w32_kill() (change suggested by

1148 2007-09-11 Paul Smith <psmith@gnu.org>
1150 * doc/make.texi (Special Variables): Moved this into the "How to
1151 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1152 (MAKEFILE_LIST) No longer a section; this was added into the
1153 "Special Variables" section.
1154 (Rule Introduction): Reference .RECIPEPREFIX.
1155 (Simple Makefile): Ditto.
1156 (Rule Syntax): Ditto.
1157 (Command Syntax): Ditto.
1158 (Error Messages): Ditto.
1160 2007-09-10 Paul Smith <psmith@gnu.org>
1162 * commands.c (print_commands): Don't print an extra line in the
1163 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1165 * read.c (construct_include_path): Add the full string to the cache; we
1166 were chopping the last char.
1168 * NEWS: Announce the .RECIPEPREFIX special variable.
1169 * variable.c (lookup_special_var): Rename from handle_special_var().
1170 (lookup_variable): Call the new name.
1171 (set_special_var): New function: handle setting of special variables.
1172 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1175 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1176 * main.c (main): Create the .RECIPEPREFIX special variable.
1177 * read.c (eval): Remove the cmd_prefix characters from the command
1178 scripts here, so they're not stored in the commands array at all,
1179 rather than waiting and stripping them out during command construction.
1180 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1182 2007-08-15 Paul Smith <psmith@gnu.org>
1184 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1185 file has had the section info removed, so add some to make.texi
1186 before we include it.
1188 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1190 * remake.c (check_dep): Reset the target state for intermediate
1191 files. They might have been considered before but not updated
1192 then (order-only for example) but they will be this time.

1206 2007-07-13 Paul Smith <psmith@gnu.org>
1208 * file.c (expand_deps): Use variable_buffer as the start of the
1209 buffer, not the original pointer (in case it was reallocated).
1210 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1211 Fixes Savannah bug #20452.

1236 * job.c (new_job): Add debug info to specify where make found the
1237 command script it is running to build a target.
1238 Fixes Savannah bug #18617.
1240 * default.c (default_suffixes,default_suffix_rules,default_variables):
1241 Add support for Objective C. Fixes Savannah bug #16389.
1242 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1244 * function.c (func_lastword): Initialize p.
1246 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1247 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1248 Dave Korn <dave.korn@artimi.com>
1250 2007-05-08 Paul Smith <psmith@gnu.org>
1252 Fix Savannah bug #19656:
1254 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1256 * make.h: Change all case-insensitive string compares to use
1257 strcasecmp() (from POSIX). If we don't have that but do have one
1258 of the others, define strcasecmp to be one of those instead. If
1259 we don't have any, declare a prototype for our own version.
1261 * misc.c (strcasecmp): Use this if we can't find any native
1262 case-insensitive string comparison function.
1263 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1264 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1266 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1267 strcasecmp() instead of stricmp().
1268 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1269 instead of strcmpi().
1270 * acinclude.m4: Remove the strcasecmp() check from here.
1272 2007-03-21 Paul Smith <psmith@gnu.org>
1274 * configure.in: Don't turn on case-insensitive file system support
1275 if --disable-... is given. Fixes Savannah bug #19348.
1277 2007-03-19 Paul Smith <psmith@gnu.org>
1279 * ALL: Use the strcache for all file name strings, or other
1280 strings which we will never free. The goal is to save memory by
1281 avoiding duplicate copies of strings. However, at the moment this
1282 doesn't save much memory in most situations: due to secondary
1283 expansion we actually save prerequisite lists twice (once before
1284 the secondary expansion, and then again after it's been parsed
1285 into individual file names in the dep list). We will resolve this
1286 in a future change, by doing the parsing up-front for targets
1287 where secondary expansion is not set.
1289 Moving things into the strcache also allows us to use const
1290 pointers in many more places.
1292 2007-01-03 Paul Smith <psmith@gnu.org>
1294 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1295 the function, not just the first. Fixes Savannah bug #18680.
1297 2006-11-18 Paul Smith <psmith@gnu.org>
1299 * strcache.c (strcache_add_len): Don't allocate a new buffer
1300 unless the string is not already nil-terminated. Technically this
1301 is a violation of the standard, since we may be passed an array
1302 that is not long enough to test one past. However, in make this
1303 is never true since we only use nil-terminated strings or
1304 sub-strings thereof.
1306 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1308 * main.c: New global cmd_prefix, defaults to '\t'.
1309 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1312 * dir.c: Constified.
1313 (dir_contents_file_exists_p): Check for an error return from
1314 readdir(), just in case.
1316 * commands.c: Constified.
1317 * default.c: Constified.
1318 * expand.c: Constified.
1319 * function.c: Partial constification.
1320 * variable.c: Partial constification.
1321 * vmsify.c: Constification. Hard to test this but I hope I didn't
1323 * vpath.c: Partial constification.
1324 * w32/pathstuff.c: Partial constification.
1326 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1328 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1329 backslashes and drive letters as absolute.
1331 2006-10-22 Paul Smith <psmith@gnu.org>
1333 * main.c (struct command_switch): Use const and void*.
1335 2006-10-21 Paul Smith <psmith@gnu.org>
1338 * arscan.c: Constified.
1340 2006-09-30 Paul Smith <psmith@gnu.org>
1342 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1343 point to lastword since the example was updated.
1344 Fixes Savannah bug #16304.
1345 (Secondary Expansion): Correct example description.
1346 Fixes Savannah bug #16468.
1347 (Makefile Contents): Clarify that comments cannot appear within
1348 variable references or function calls.
1349 Fixes Savannah bug #16577.
1350 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1351 Fixes Savannah bug #17701.
1352 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1354 prerequisites. Fixes Savannah bug #17880.
1355 (Rule Syntax): "lise" -> "list"
1356 (Multiple Rules): ... -> @dots{}
1357 (Splitting Lines): ditto.
1359 * remake.c (update_file_1): Prereqs that don't exist should be
1360 considered changed, for the purposes of $?.
1361 Fixes Savannah bug #16051.
1363 * make.1: Remove extraneous "+".
1364 Fixes Savannah bug #16652.

1381 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1382 sh_chars_sh for Windows platforms that emulate Unix.

1400 2006-04-20 Paul D. Smith <psmith@gnu.org>
1402 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1403 that don't have extended grep.
1404 (cvsclean): Use $(PERL) instead of perl.
1406 2006-04-09 Paul D. Smith <psmith@gnu.org>
1408 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1410 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1411 inner-scope variables don't mask outer-scope variables.
1413 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1414 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1415 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1416 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1417 values from memory allocation functions: they return void* and so
1418 don't need to be cast. Also remove (char *) casts of arguments to
1421 * configure.in: Remove checks for memcpy/memmove/strchr.
1423 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1425 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp

1429 * variable.c, vpath.c: Ditto.
1431 * make.h (EXIT_FAILURE): Should be 1, not 0.
1433 2006-04-06 Paul D. Smith <psmith@gnu.org>
1435 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1436 require an ISO C 1989 standard compiler and runtime library.

1464 support from automake, as described in the Texinfo manual.
1466 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1468 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1469 with lastslash, since the latter points to filename, not to
1471 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1472 Declare and define sh_chars_sh[].
1474 2006-03-23 Paul D. Smith <psmith@gnu.org>
1476 * configure.in: Look for build.sh.in in $srcdir so it will be
1477 built for remote configurations as well.
1479 * Makefile.am: Make sure to clean up build.sh during distclean.
1480 Fixes Savannah bug #16166.
1482 * misc.c (log_access): Takes a const char *.

1486 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1488 * implicit.c (pattern_search): Call set_file_variables only
1489 if we have prerequisites that need second expansion. Fixes
1490 Savannah bug #16140.

1494 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1495 memory on hosts that don't support it directly.
1497 * README.cvs: Add information on steps for making a release (to
1498 make sure I don't forget any).
1500 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1502 (die): Cleanup code was removed from here; call the new function.
1503 (main): If we are re-execing, clean up the jobserver first so we
1504 don't leak file descriptors.

1507 2006-03-17 Paul D. Smith <psmith@gnu.org>

1516 * misc.c (alloc_dep, free_dep): New functions.
1517 (copy_dep_chain): Copy stem.
1518 (free_dep_chain): Use free_dep.
1519 * read.c (record_files): Store stem in the dependency line.
1520 * file.c (expand_deps): Use stem stored in the dependency line. Use
1521 free_dep_chain instead of free_ns_chain.

1528 2006-03-14 Paul D. Smith <psmith@gnu.org>
1530 * expand.c (variable_append): Instead of appending everything then
1531 expanding the result, we expand (or not, if it's simple) each part
1533 (allocated_variable_append): Don't expand the final result.
1534 Fixes Savannah bug #15913.
1536 2006-03-09 Paul Smith <psmith@gnu.org>
1538 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1539 listed non-existent files as changed. Turns out there's a bug in
1540 the Linux kernel builds which means that this change causes
1541 everything to rebuild every time. We will re-introduce this fix
1542 in the next release, to give them time to fix their build system.
1543 Fixes Savannah bug #16002.
1544 Introduces Savannah bug #16051.
1546 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1547 we *don't* find UNIX "/".

1553 locator function find_and_set_default_shell if SHELL came from the

1558 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1559 to be null; don't core in that case.
1561 2006-02-19 Paul D. Smith <psmith@gnu.org>
1563 * commands.c (set_file_variables): Realloc, not malloc, the static
1564 string values to avoid memory leaks.
1566 * expand.c (recursively_expand_for_file): Only set reading_file to
1567 an initialized value.
1569 * implicit.c (pattern_search): We need to make a copy of the stem
1570 if we get it from an intermediate dep, since those get freed.
1572 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1574 (enter_file) [VMS]: Ditto.
1575 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1577 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1579 * job.c (construct_command_argv_internal): Fix last change.
1581 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1582 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1583 the calls to _beginthreadex.
1585 * expand.c (recursively_expand_for_file): Initialize `save' to
1586 prevent compiler warnings.
1588 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1590 * job.c (construct_command_argv_internal): Don't create a temporary
1591 script/batch file if we are under -n. Call _setmode to switch the
1592 script file stream to text mode.
1594 2006-02-17 Paul D. Smith <psmith@gnu.org>
1596 * variable.c (merge_variable_set_lists): Don't try to merge the
1597 global_setlist. Not only is this useless, but it can lead to
1598 circularities in the linked list, if global_setlist->next in one
1599 list gets set to point to another list which also ends in
1601 Fixes Savannah bug #15757.
1603 2006-02-15 Paul D. Smith <psmith@gnu.org>
1605 Fix for Savannah bug #106.
1607 * expand.c (expanding_var): Keep track of which variable we're
1608 expanding. If no variable is being expanded, it's the same as
1610 * make.h (expanding_var): Declare it.
1611 * expand.c (recursively_expand_for_file): Set expanding_var to the
1612 current variable we're expanding, unless there's no file info in
1613 it (could happen if it comes from the command line or a default
1614 variable). Restore it before we exit.
1615 * expand.c (variable_expand_string): Use the expanding_var file
1616 info instead of the reading_file info.
1617 * function.c (check_numeric): Ditto.
1619 (func_wordlist): Ditto.
1620 (func_error): Ditto.
1621 (expand_builtin_function): Ditto.
1622 (handle_function): Ditto.
1624 2006-02-14 Paul D. Smith <psmith@gnu.org>
1626 * read.c (eval): Even if the included filenames expands to the
1627 empty string we still need to free the allocated buffer.
1629 * implicit.c (pattern_search): If we allocated a variable set for
1630 an impossible file, free it.
1631 * variable.c (free_variable_set): New function.
1632 * variable.h: Declare it.
1634 * read.c (read_all_makefiles): Makefile names are kept in the
1635 strcache, so there's never any need to alloc/free them.
1638 * main.c (main): Add "archives" to the .FEATURES variable if
1639 archive support is enabled.
1640 * doc/make.texi (Special Variables): Document it.
1642 2006-02-13 Paul D. Smith <psmith@gnu.org>
1644 * implicit.c (pattern_search): Add checking for DOS pathnames to
1645 the pattern rule target LASTSLASH manipulation.

1650 * (ALL FILES): Updated copyright and license notices.
1652 2006-02-10 Paul D. Smith <psmith@gnu.org>
1654 A new internal capability: the string cache is a read-only cache
1655 of strings, with a hash table interface for fast lookup. Nothing
1656 in the cache will ever be freed, so there's no need for reference
1657 counting, etc. This is the beginning of a full solution for
1658 Savannah bug #15182, but for now we only store makefile names here.
1660 * strcache.c: New file. Implement a read-only string cache.
1661 * make.h: Add prototypes for new functions.
1662 * main.c (initialize_global_hash_tables): Initialize the string cache.
1663 (print_data_base): Print string cache stats.
1664 * read.c (eval_makefile): Use the string cache to store makefile
1665 names. Rewrite the string allocation to be sure we free everything.

1669 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1670 directory time stamp didn't change, except on FAT filesystems.
1671 Suggested by J. David Bryan <jdbryan@acm.org>.
1673 2006-02-09 Paul D. Smith <psmith@gnu.org>
1675 * function.c (func_or): Implement a short-circuiting OR function.
1676 (func_and): Implement a short-circuiting AND function.
1677 (function_table_init): Update the table with the new functions.
1678 * doc/make.texi (Conditional Functions): Changed the "if" section
1679 to one on general conditional functions. Added documentation for
1680 $(and ...) and $(or ...) functions.
1681 * NEWS: Note new $(and ...) and $(or ...) functions.
1683 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1685 * job.h (struct child): Add the dontcare bitfield.
1686 * job.c (new_job): Cache dontcare flag.
1687 * job.c (reap_children): Use cached dontcare flag instead of the
1688 one in struct file. Fixes Savannah bug #15641.
1690 2006-02-06 Paul D. Smith <psmith@gnu.org>
1692 * vpath.c (selective_vpath_search): If the file we find has a
1693 timestamp from -o or -W, use that instead of the real time.
1694 * remake.c (f_mtime): If the mtime is a special token from -o or
1695 -W, don't overwrite it with the real mtime.
1696 Fixes Savannah bug #15341.

1713 Fixes Savannah bug #15533.
1714 * filedef.h (struct file): Add a new LAST pointer.
1716 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1717 the comparison. For 64-bits systems the result of the subtraction
1718 might not fit into an int. Use comparison instead.
1719 Fixes Savannah bug #15534.
1721 * doc/make.texi: Update the chapter on writing commands to reflect
1722 the changes made in 3.81 for backslash/newline and SHELL handling.

1742 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1744 * remake.c (update_goal_chain): Set g->changed instead of
1745 incrementing it, as it is only 8-bit wide, and could overflow if
1746 many commands got started in update_file.
1748 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1750 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1751 MAXIMUM_WAIT_OBJECTS.
1752 (process_wait_for_any_private): Change dimension of handles[]
1753 array to MAXIMUM_WAIT_OBJECTS.

1755 (process_register): Don't register more processes than the
1756 available number of slots.
1757 (process_easy): Don't start new processes if all slots are used up.
1759 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1760 are already more children than sub_proc.c can handle, behave as if
1761 the load were too high.
1762 (start_job_command): Fix a typo in error message when process_easy
1765 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1767 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1768 the shell is not sh.exe.
1770 * job.c (create_batch_file): Renamed from create_batch_filename;
1771 all callers changed. Don't close the temporary file; return its
1772 file descriptor instead. New arg FD allows to return the file
1774 (construct_command_argv_internal): Use _fdopen instead of fopen to
1775 open the batch file.
1777 2006-01-04 Paul D. Smith <psmith@gnu.org>
1779 * readme.vms: Updates for case-insensitive VMS file systems from
1780 Hartmut Becker <Hartmut.Becker@hp.com>.

1800 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1801 disable warnings for MSC.
1802 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1804 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1806 * doc/make.texi (Execution): Add a footnote about changes in
1807 handling of backslash-newline sequences. Mention the differences
1808 on MS-DOS and MS-Windows.
1810 * NEWS: More details about building the MinGW port and a pointer
1811 to README.W32. Fix the section name that describes the new
1812 backward-incompatible processing of backslash-newline sequences.
1813 The special processing of SHELL set to "cmd" is only relevant to
1814 MS-Windows, not MS-DOS.
1816 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1818 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1819 to DWORD, to avoid compiler warnings.
1820 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1821 use %ld in format, to avoid compiler warnings.
1823 * doc/make.texi (Special Targets): Fix a typo.
1824 (Appending): Fix cross-reference to Setting.
1825 (Special Variables, Secondary Expansion, File Name Functions)

1835 * read.c (record_target_var): Initialize variable's export field
1836 with v_default instead of leaving it "initialized" by whatever
1837 garbage happened to be on the heap.

1841 * make.1: Fix some display errors and document all existing options.
1842 Patch by Mike Frysinger <vapier@gentoo.org>.
1844 2005-12-11 Paul D. Smith <psmith@gnu.org>
1846 * implicit.c (pattern_search): If 2nd expansion is not set for
1847 this implicit rule, replace the pattern with the stem directly,
1848 and don't re-expand the variable list. Along with the other
1849 .SECONDEXPANSION changes below, fixes bug #13781.
1851 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1853 * implicit.c (pattern_search): Mark other files that this rule
1854 builds as targets so that they are not treated as intermediates
1855 by the pattern rule search algorithm. Fixes bug #13022.
1857 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1859 * remake.c (notice_finished_file): Propagate the change of

1880 * maintMakefile: We only need to build the templates when we are
1881 creating a distribution, so don't do it for "all".
1883 2005-10-24 Paul D. Smith <psmith@gnu.org>
1885 Make secondary expansion optional: its enabled by declaring the
1886 special target .SECONDEXPANSION.
1888 * NEWS: Update information on second expansion capabilities.
1889 * doc/make.texi (Secondary Expansion): Document the
1890 .SECONDEXPANSION special target and its behavior.

1893 (free_dep_chain): Declare a prototype.
1894 * file.c (parse_prereqs): New function: break out some complexity
1896 (expand_deps): If we aren't doing second expansion, replace % with
1897 the stem for static pattern rules. Call the new function.
1898 * filedef.h (parse_prereqs): Declare a prototype.
1899 * implicit.c (pattern_search): Initialize the new staticpattern
1901 * main.c (second_expansion): Declare a global variable to remember
1902 if the special target has been seen. Initialize the new
1903 staticpattern field for prerequisites.
1904 * make.h: Extern for second_expansion.
1905 * misc.c (free_dep_chain): New function: frees a struct dep list.
1906 * read.c (read_all_makefiles): Initialize the staticpattern field.
1907 (eval_makefile): Ditto.
1908 (record_files): Check for the .SECONDEXPANSION target and set
1909 second_expansion global if it's found.

1911 Set the staticpattern field for prereqs of static pattern targets.
1913 2005-10-16 Paul D. Smith <psmith@gnu.org>
1915 * main.c (main): Set CURDIR to be a file variable instead of a
1916 default, so that values of CURDIR inherited from the environment
1917 won't override the make value.
1919 2005-09-26 Paul D. Smith <psmith@gnu.org>
1921 * job.c (construct_command_argv_internal): If the line is empty
1922 remember to free the temporary argv strings.
1925 2005-09-16 Paul D. Smith <psmith@gnu.org>
1927 * job.c (start_job_command): The noerror flag is a boolean (single
1928 bit); set it appropriately.
1929 Reported by Mark Eichin <eichin@metacarta.com>
1931 2005-08-29 Paul D. Smith <psmith@gnu.org>
1933 * function.c (func_error): On Windows, output from $(info ...)
1934 seems to come in the wrong order. Try to force it with fflush().
1936 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1938 * read.c (record_files): Move code that sets stem for static
1939 pattern rules out of the if (!two_colon) condition so it is
1940 also executed for two-colon rules. Fixes Savannah bug #13881.
1942 2005-08-08 Paul D. Smith <psmith@gnu.org>
1944 * make.h: Don't test that __STDC__ is non-0. Some compilers
1945 (Windows for example) set it to 0 to denote "ISO C + extensions".
1948 2005-08-07 Paul D. Smith <psmith@gnu.org>
1950 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1951 conditional (slightly different version of a fix from Eli).
1953 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1954 If make is running in parallel without -k and two jobs die in a
1955 row, but not too close to each other, then make will quit without
1956 waiting for the rest of the jobs to die.
1958 * main.c (die): Don't reset err before calling reap_children() the
1959 second time: we still want it to be in the error condition.
1960 * job.c (reap_children): Use a static variable, rather than err,
1961 to control whether or not the error message should be printed.
1963 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1965 * w32/subproc/sub_proc.c: Include signal.h.
1966 (process_pipe_io, process_file_io): Pass a pointer to a local
1967 DWORD variable to GetExitCodeProcess. If the exit code is
1968 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1970 * job.c [WINDOWS32]: Include windows.h.
1971 (main_thread) [WINDOWS32]: New global variable.
1972 (reap_children) [WINDOWS32]: Get the handle for the main thread
1973 and store it in main_thread.
1975 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1976 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1977 doing anything else. When we are done, close the main thread
1978 handle and exit with status 130.
1980 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1982 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1985 * main.c (find_and_set_default_shell): If found a DOSish shell,
1986 set sh_found and the value of default_shell, and report the
1987 findings in debug mode.
1989 * job.c (construct_command_argv_internal): Check unixy_shell, not
1990 no_default_sh_exe, to decide whether to use Unixy or DOSish
1993 * README.W32: Update with info about the MinGW build.
1995 * build_w32.bat: Support MinGW.
1997 * w32/subproc/build.bat: Likewise.
1999 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2000 printing DWORD args.
2002 * function.c (windows32_openpipe): Fix format strings for printing
2005 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2007 (start_job_command): Fix format string for printing the result of
2009 (start_job_command) [WINDOWS32]: Do not define.
2010 (exec_command): Fix format string for printing HANDLE args.
2012 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2013 to avoid compiler warnings.
2014 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.

2027 backslash-newline behavior (where they are stripped).
2030 2005-07-08 Paul D. Smith <psmith@gnu.org>
2032 * config.h.W32.template: Reorder to match the standard config.h,
2033 for easier comparisons.
2034 From J. Grant <jg@jguk.org>
2036 * maintMakefile: Remove .dep_segment before overwriting it, in
2037 case it's not writable or noclobber is set.
2038 * expand.c (variable_expand_string): Cast result of pointer
2039 arithmetic to avoid a warning.
2040 * main.c (switches): Add full-fledged final initializer.
2042 2005-07-06 Paul D. Smith <psmith@gnu.org>
2044 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2045 * signame.c (strsignal): If we found _sys_siglist[] or
2046 __sys_siglist[] use those instead of sys_siglist[].
2047 From Albert Chin <china@thewrittenword.com>
2049 2005-07-04 Paul D. Smith <psmith@gnu.org>
2051 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2052 globfree(); set up to use the GNU versions.
2053 From Martin Zinser <zinser@zinser.no-ip.info>
2055 2005-07-03 Paul D. Smith <psmith@gnu.org>
2057 From J. Grant <jg@jguk.org>:

2063 * w32/subproc/build.bat: Ditto.
2065 2005-06-28 Paul D. Smith <psmith@gnu.org>
2067 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2068 declaration was checked but not present.
2070 2005-06-27 Paul D. Smith <psmith@gnu.org>
2072 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2073 to unsigned long. Fixes Savannah bug #13550.
2075 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2076 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.

2079 2005-06-26 Paul D. Smith <psmith@gnu.org>
2081 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2082 it if ANSI_STRING is not set.
2084 2005-06-25 Paul D. Smith <psmith@gnu.org>
2086 * read.c (eval): If no filenames are passed to any of the
2087 "include" variants, don't print an error.
2088 * doc/make.texi (Include): Document this.
2089 Fixes Savannah bug #1761.
2091 * job.c (construct_command_argv_internal): Sanitize handling of
2092 backslash/newline pairs according to POSIX: that is, keep the
2093 backslash-newline in the command script, but remove a following
2094 TAB character, if present. In the fast path, make sure that the
2095 behavior matches what the shell would do both inside and outside
2096 of quotes. In the slow path, quote the backslash and put a
2097 literal newline in the string.
2098 Fixes Savannah bug #1332.
2099 * doc/make.texi (Execution): Document the new behavior and give
2101 * NEWS: Make a note of the new behavior.
2103 * make.h [WINDOWS32]: #include <direct.h>.
2104 Fixes Savannah bug #13478.
2106 * remake.c (name_mtime): If the stat() of a file fails and the -L
2107 option was given and the file is a symlink, take the best mtime of
2108 the symlink we can get as the mtime of the file and don't fail.
2109 Fixes Savannah bug #13280.
2111 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2112 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2113 inside a variable reference. Make this function static as it's
2115 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2116 parsing an unexpanded line looking for semicolons.
2117 Fixes Savannah bug #1454.
2118 * misc.c (remove_comments): Move this to read.c and make it static
2119 as it's only used there. Call find_char_unquote() with new arg.
2120 * make.h: Remove prototypes for find_char_unquote() and
2121 remove_comments() since they're static now.
2123 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2124 its export flag and obtain its value. When we need to re-exec,
2125 increment the value and add it into the environment.
2126 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2127 * NEWS: Mention MAKE_RESTARTS.
2128 * main.c (always_make_set): New variable. Change the -B option to
2129 set this one instead.
2130 (main): When checking makefiles, only set always_make_flag if
2131 always_make_set is set AND the restarts flag is 0. When building
2132 normal targets, set it IFF always_make_set is set.
2133 (main): Avoid infinite recursion with -W, too: only set what-if
2134 files to NEW before we check makefiles if we've never restarted
2135 before. If we have restarted, set what-if files to NEW _after_ we
2137 Fixes Savannah bug #7566:
2139 2005-06-17 Paul D. Smith <psmith@gnu.org>
2141 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2142 in the prerequisites list.
2144 2005-06-12 Paul D. Smith <psmith@gnu.org>
2146 Fix Savannah bug # 1328.
2148 * configure.in: Check for atexit().
2149 * misc.c (close_stdout): Test stdout to see if writes to it have
2150 failed. If so, be sure to exit with a non-0 error code. Based on
2151 code found in gnulib.
2152 * make.h: Prototype.
2153 * main.c (main): Install close_stdout() with atexit().
2155 2005-06-10 Paul D. Smith <psmith@gnu.org>
2157 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2159 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2160 headers; make vmsWaitForChildren() static; extern vmsify().
2161 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2162 Don't create child_execute_job() here (it's in vmsjobs.c).
2163 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2165 2005-06-09 Paul D. Smith <psmith@gnu.org>
2167 * variable.c (push_new_variable_scope): File variables point
2168 directly to the global_setlist variable. So, inserting a new
2169 scope in front of that has no effect on those variables: they
2170 don't go through current_variable_set_list. If we're pushing a
2171 scope and the current scope is global, push it "the other way" so
2172 that the new setlist is in the global_setlist variable, and
2173 next points to a new setlist with the global variable set.
2174 (pop_variable_scope): Properly undo a push with the new
2176 Fixes Savannah bug #11913.
2178 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2180 * job.c (reap_children): Don't die of the command failed but
2181 the dontcare flag is set. Fixes Savannah bug #13216.
2183 * implicit.c (pattern_search): When creating a target from
2184 an implicit rule match, lookup pattern target and set precious
2185 flag in a newly created target. Fixes Savannah bug #13218.
2187 2005-05-13 Paul D. Smith <psmith@gnu.org>
2189 Implement "if... else if... endif" syntax.
2191 * read.c (eval): Push all checks for conditional words ("ifeq",
2192 "else", etc.) down into the conditional_line() function.
2193 (conditional_line): Rework to allow "else if..." clause. New
2194 return value -2 for lines which are not conditionals. The
2195 ignoring flag can now also be 2, which means "already parsed a
2196 true branch". If that value is seen no other branch of this
2197 conditional can be considered true. In the else parsing if there
2198 is extra text after the else, invoke conditional_line()
2199 recursively to see if it's another conditional. If not, it's an
2200 error. If so, raise the conditional value to this level instead
2201 of creating a new conditional nesting level. Special check for
2202 "else" and "endif", which aren't allowed on the "else" line.
2203 * doc/make.texi (Conditional Syntax): Document the new syntax.
2205 2005-05-09 Paul D. Smith <psmith@gnu.org>
2207 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2208 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2209 recurses to the w32 directory, even on non-Windows systems. Use
2210 the method suggested in the automake manual.
2211 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2212 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2214 2005-05-07 Paul D. Smith <psmith@gnu.org>
2216 * main.c (die): If we're dying with a fatal error (not that a
2217 command has failed), write back any leftover tokens before we go.
2219 * job.c (set_child_handler_action_flags): If there are jobs
2220 waiting for the load to go down, set an alarm to go off in 1
2221 second. This allows us to wake up from a potentially long-lasting
2222 read() and start a new job if the load has gone down. Turn it off
2224 (job_noop): Dummy signal handler function.
2225 (new_job): Invoke it with the new semantics.
2227 * docs/make.texi: Document secondary expansion. Various cleanups
2230 2005-05-03 Paul D. Smith <psmith@gnu.org>
2232 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2233 the targets which are to ultimately be made are called "goals";
2234 see the GNU make manual. Also, MAKECMDGOALS, etc.
2236 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2237 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2238 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2240 2005-05-02 Paul D. Smith <psmith@gnu.org>
2242 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2243 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2244 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2245 functions to vmsjobs.c. #include it into jobs.c.
2247 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2248 jobserver tokens. I found that this happens when an exported
2249 recursive variable contains a $(shell ...) function reference: in
2250 this situation we could "forget" to write back a token.
2252 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2253 we have. It's not reliable to depend on the number of children in
2254 our linked list so keep a separate count.
2255 (new_job): Check jobserver_tokens rather than children &&
2256 waiting_jobs. Increment jobserver_tokens when we get one.
2257 (free_child): If jobserver_tokens is 0, internal error. If it's
2258 >1, write a token back to the jobserver pipe (we don't write a
2259 token for the "free" job). Decrement jobserver_tokens.
2261 * main.c: Add variable master_job_slots.
2262 (main): Set it to hold the number of jobs requested if we're the
2263 master process, when using the jobserver.
2264 (die): Sanity checks: first test jobserver_tokens to make sure
2265 this process isn't holding any tokens we didn't write back.
2266 Second, if master_job_slots is set count the tokens left in the
2267 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2269 2005-04-24 Paul D. Smith <psmith@gnu.org>
2271 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2272 with -l# can lose jobserver tokens, because waiting jobs are not
2273 consulted properly when checking for the "free" token.
2275 * job.c (free_child): Count waiting_jobs as having tokens.
2276 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2277 handle jobs waiting for the load to drop.
2279 2005-04-23 Paul D. Smith <psmith@gnu.org>
2281 * main.c (main): Be careful to not core if a variable setting in
2282 the environment doesn't contain an '='. This is illegal but can
2283 happen in broken setups.
2284 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2286 2005-04-12 Paul D. Smith <psmith@gnu.org>
2288 The second expansion feature causes significant slowdown. Timing
2289 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2290 read the makefile before the feature, to 11+s to do the same
2291 operations after the feature. Additionally, memory usage
2292 increased drastically. To fix this I added some intelligence that
2293 avoids the overhead of the second expansion unless it's required.
2295 * dep.h: Add a new boolean field, need_2nd_expansion.
2297 * read.c (eval): When creating the struct dep for the target,
2298 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2299 (record_files): If there's a "%" in a static pattern rule, it gets
2300 converted to "$*" so set need_2nd_expansion to 1.
2302 * file.c (expand_deps): Rework to be more efficient. Only perform
2303 initialize_file_variables(), set_file_variables(), and
2304 variable_expand_for_file() if the need_2nd_expansion is set.
2306 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2307 (pattern_search): Ditto.
2308 * main.c (handle_non_switch_argument): Ditto.
2310 * read.c (read_all_makefiles): Ditto.
2311 (eval_makefile): Ditto.
2313 2005-04-07 Paul D. Smith <psmith@gnu.org>
2315 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2316 * variable.c (sync_Path_environment): Ditto.
2317 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2319 * main.c (main): Define the .FEATURES variable.
2320 * NEWS: Announce .FEATURES.
2321 * doc/make.texi (Special Variables): Document .FEATURES.
2323 * remake.c (check_dep): If a file is .PHONY, update it even if
2324 it's marked intermediate. Fixes Savannah bug #12331.
2326 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2328 * file.c (expand_deps): Factor out the second expansion and
2329 prerequisite line parsing logic from snap_deps().
2331 * file.c (snap_deps): Use expand_deps(). Expand and parse
2332 prerequisites of the .SUFFIXES special target first. Fixes
2333 Savannah bug #12320.
2335 2005-03-13 Paul D. Smith <psmith@gnu.org>
2337 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2340 2005-03-11 Paul D. Smith <psmith@gnu.org>
2342 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2343 available, not undefined (from Earnie Boyd).
2345 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2347 * implicit.c (pattern_search): Mark an intermediate target as
2348 precious if it happened to be a prerequisite of some (other)
2349 target. Fixes Savannah bug #12267.
2351 2005-03-09 Paul D. Smith <psmith@gnu.org>
2353 * read.c (eval_makefile): Add alloca(0).
2354 (eval_buffer): Ditto.
2356 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2358 * main.c (main): Use o_file instead of o_default when defining
2359 the .DEFAULT_TARGET special variable.
2360 * read.c (eval): Use define_variable_global() instead of
2361 define_variable() when setting new value for the .DEFAULT_TARGET
2362 special variable. Fixes Savannah bug #12266.
2364 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2366 * imlicit.c (pattern_search): Mark files for which an implicit
2367 rule has been found as targets. Fixes Savannah bug #12202.
2369 2005-03-04 Paul D. Smith <psmith@gnu.org>
2372 * doc/make.texi (Automatic Variables): Document $|.
2374 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2376 * read.c (record_files): Instead of substituting % with
2377 actual stem value in dependency list replace it with $*.
2378 This fixes stem triple expansion bug.
2380 * implicit.c (pattern_search): Copy stem to a separate
2381 buffer and make it a properly terminated string. Assign
2382 this buffer instead of STEM (which is not terminated) to
2383 f->stem. Instead of substituting % with actual stem value
2384 in dependency list replace it with $*. This fixes stem
2385 triple expansion bug.
2387 2005-03-01 Paul D. Smith <psmith@gnu.org>
2389 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2390 on Windows, as it takes a handle not a pid. Just exit.
2391 Fix from patch #3679, provided by Alessandro Vesely.
2393 * configure.in: Update check for sys_siglist[] from autoconf manual.
2394 * signame.c (strsignal): Update to use the new autoconf macro.
2396 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2398 * read.c (record_files): Add a check for the list of prerequisites
2399 of a static pattern rule being empty. Fixes Savannah bug #12180.
2401 2005-02-28 Paul D. Smith <psmith@gnu.org>
2403 * doc/make.texi (Text Functions): Update docs to allow the end
2404 ordinal for $(wordlist ...) to be 0.
2405 * function.c (func_wordlist): Fail if the start ordinal for
2406 $(wordlist ...) is <1. Matches documentation.
2407 Resolves Savannah support request #103195.
2409 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2410 previously we were stopping when !-q, exactly the opposite. This
2411 has been wrong since version 1.34, in 1994!
2412 (update_file): If we got an error don't break out to run more
2413 double-colon rules: just return immediately.
2414 Fixes Savannah bug #7144.
2416 2005-02-27 Paul D. Smith <psmith@gnu.org>
2418 * misc.c (end_of_token): Make argument const.
2419 * make.h: Update prototype.
2421 * function.c (abspath, func_realpath, func_abspath): Use
2422 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2423 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2424 * read.c (record_files): Ditto.
2425 * variable.c (do_variable_definition): Ditto.
2427 * function.c (func_error): Create a new function $(info ...) that
2428 simply prints the message to stdout with no extras.
2429 (function_table_init): Add new function to the table.
2430 * NEWS: Add $(info ...) reference.
2431 * doc/make.texi (Make Control Functions): Document it.
2433 New feature: if the system supports symbolic links, and the user
2434 provides the -L/--check-symlink-time flag, then use the latest
2435 mtime between the symlink(s) and the target file.
2437 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2438 readlink(). If both are available, define MAKE_SYMLINKS.
2439 * main.c: New variable: check_symlink_flag.
2440 (usage): Add a line for -L/--check-symlink-times to the help string.
2441 (switches): Add -L/--check-symlink-times command line argument.
2442 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2443 print a warning and disable it again.
2444 * make.h: Declare check_symlink_flag.
2445 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2446 if the file is a symlink then check each link in the chain and
2447 choose the NEWEST mtime we find as the mtime for the file. The
2448 newest mtime might be the file itself!
2449 * NEWS: Add information about this new feature.
2450 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2452 Avoid core dumps described in Savannah bug # 12124:
2454 * file.c: New variable snapped_deps remember whether we've run
2456 (snap_deps): Set it.
2457 * filedef.h: Extern it.
2458 * read.c (record_files): Check snapped_deps; if it's set then
2459 we're trying to eval a new target/prerequisite relationship from
2460 within a command script, which we don't support. Fatal.
2462 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2464 Implementation of the .DEFAULT_TARGET special variable.
2466 * read.c (eval): If necessary, update default_target_name when
2468 * read.c (record_files): Update default_target_file if
2469 default_target_name has changed.
2470 * main.c (default_target_name): Define.
2471 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2472 default_target_name is set use default_target_file as a root
2474 * filedef.h (default_target_name): Declare.
2475 * dep.h (free_dep_chain):
2476 * misc.c (free_dep_chain): Change to operate on struct nameseq
2477 and change name to free_ns_chain.
2478 * file.c (snap_deps): Update to use free_ns_chain.
2480 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2482 Implementation of the second expansion in explicit rules,
2483 static pattern rules and implicit rules.
2485 * read.c (eval): Refrain from chopping up rule's dependencies.
2486 Store them in a struct dep as a single dependency line. Remove
2487 the code that implements SySV-style automatic variables.
2489 * read.c (record_files): Adjust the code that handles static
2490 pattern rules to expand all percents instead of only the first
2491 one. Reverse the order in which dependencies are stored so that
2492 when the second expansion reverses them again they appear in
2493 the makefile order (with some exceptions, see comments in
2494 the code). Remove the code that implements SySV-style automatic
2497 * file.c (snap_deps): Implement the second expansion and chopping
2498 of dependency lines for explicit rules.
2500 * implicit.c (struct idep): Define an auxiliary data type to hold
2501 implicit rule's dependencies after stem substitution and
2504 * implicit.c (free_idep_chain): Implement.
2506 * implicit.c (get_next_word): Implement helper function for
2507 parsing implicit rule's dependency lines into words taking
2508 into account variable expansion requests. Used in the stem
2511 * implicit.c (pattern_search): Implement the second expansion
2512 for implicit rules. Also fixes bug #12091.
2514 * commands.h (set_file_variables): Declare.
2515 * commands.c (set_file_variables): Remove static specifier.
2517 * dep.h (free_dep_chain): Declare.
2518 * misc.c (free_dep_chain): Implement.
2520 * variable.h (variable_expand_for_file): Declare.
2521 * expand.c (variable_expand_for_file): Remove static specifier.
2523 * make.h (strip_whitespace): Declare.
2524 * function.c (strip_whitespace): Remove static specifier.
2526 2005-02-26 Paul D. Smith <psmith@gnu.org>
2528 * main.c (main): Check for ferror() when reading makefiles from stdin.
2529 Apparently some shells in Windows don't close pipes properly and
2532 2005-02-24 Jonathan Grant <jg@jguk.org>
2534 * configure.in: Add MinGW configuration options, and extra w32 code
2536 * Makefile.am: Add MinGW configuration options, and extra w32 code
2538 * main.c: Determine correct program string (after last \ without .exe).
2539 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2541 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2542 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2543 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2544 environment support.
2546 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2548 * function.c (func_shell): When initializing error_prefix, check
2549 that reading file name is not null. This fixes long-standing
2550 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2552 2005-02-09 Paul D. Smith <psmith@gnu.org>
2554 * maintMakefile: Update the CVS download URL to simplify them.
2555 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2556 downloading the .texi files from Savannah now.
2558 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2560 * main.c (handle_non_switch_argument): Only add variables to
2561 command_variables if they're not already there: duplicate settings
2562 waste space and can be confusing to read.
2564 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2565 this header is never included by non-WINDOWS32 code, and it
2566 requires <config.h> to define which isn't always included first.
2568 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2569 testing MINGW32 versions.
2571 * main.c (log_working_directory): flush stdout to be sure the WD
2572 change is printed before any stderr messages show up.
2574 2005-02-01 Paul D. Smith <psmith@gnu.org>
2576 * maintMakefile (po_repo): Update the GNU translation site URL.
2578 2004-12-01 Paul D. Smith <psmith@gnu.org>
2580 * main.c (main): Change char* env_shell to struct variable shell_var.
2581 * variable.c (target_environment): Use new shell_var.
2583 2004-11-30 Paul D. Smith <psmith@gnu.org>
2585 * configure.in: The old way we avoided creating build.sh from
2586 build.sh.in before build.sh.in exists doesn't work anymore; we
2587 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2588 the help!). This also keeps automake from complaining.
2589 * Makefile.am (README): Add a dummy target so automake won't
2590 complain that this file doesn't exist when we checkout from CVS.
2591 * maintMakefile (.dep_segment): Rewrite this rule since newer
2592 versions of automake don't provide DEP_FILES.
2594 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2596 Implementation of `realpath' and `abspath' built-in functions.
2598 * configure.in: Check for realpath.
2599 * function.c (abspath): Return an absolute file name that does
2600 not contain any `.' or `..' components, nor repeated `/'.
2601 * function.c (func_abspath): For each name call abspath.
2602 * function.c (func_realpath): For each name call realpath
2603 from libc or delegate to abspath if realpath is not available.
2604 * doc/make.texi (Functions for File Names): Document new functions.
2605 * doc/make.texi (Quick Reference): Ditto.
2607 2004-11-28 Paul D. Smith <psmith@gnu.org>
2609 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2610 arguments. Fixes bug #10252.
2612 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2614 * main.c (main): Set SHELL to v_noexport by default. Remember the
2615 original environment setting of SHELL in the env_shell variable.
2616 * main.h: Export new env_shell variable.
2617 * variable.c (target_environment): If we find a v_noexport
2618 variable for SHELL, add a SHELL variable with the env_shell value.
2619 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2620 * doc/make.texi (Variables/Recursion): Ditto.
2622 2004-11-28 Paul D. Smith <psmith@gnu.org>
2624 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2625 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2626 Patch by Alessandro Vesely.
2628 2004-11-12 Paul D. Smith <psmith@gnu.org>
2630 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2631 the command line if it's inside a string.
2632 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2634 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2636 * function.c (func_lastword): New function: return last word
2637 from the list of words.
2638 * doc/make.texi: Document $(lastword ). Fix broken links in
2639 Quick Reference section.
2641 2004-10-06 Paul D. Smith <psmith@gnu.org>
2643 Apply patch from Alessandro Vesely, provided with bug # 9748.
2644 Fix use of tmpnam() to work with Borland C.
2646 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2647 construction of a temporary filename, and call new function
2648 create_batch_filename().
2649 (create_batch_filename) [WINDOWS32]: New function to create a
2652 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2654 * read.c (record_target_var): Expand simple pattern-specific
2656 * variable.c (initialize_file_variables): Do not expand simple
2657 pattern-specific variable.
2659 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2661 * remake.c (update_file_1): When rebuilding makefiles inherit
2662 dontcare flag from a target that triggered update.
2664 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2666 * variable.c (initialize_file_variables): Mark pattern-specific
2667 variable as a per-target and copy export status.
2669 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2671 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2673 * implicit.c (pattern_search): When considering an implicit rule's
2674 prerequisite check that it is actually a target rather then
2675 just an entry in the file hashtable.
2677 2004-09-21 Paul D. Smith <psmith@gnu.org>
2679 * read.c (readstring): Fix some logic errors in backslash handling.
2680 (eval): Remove some unnecessary processing in buffer handling.
2681 (record_target_var): Assert that parse_variable_definition() succeeded.
2682 Reported by: Markus Mauhart <qwe123@chello.at>.
2684 * misc.c: Removed the sindex() function. All instances of this
2685 function were trivially replaceable by the standard strstr()
2686 function, and that function will always have better (or certainly
2687 no worse) performance than the very simple-minded algorithm
2688 sindex() used. This can matter with complex makefiles.
2689 * make.h: Remove the prototype for sindex().
2690 * function.c (subst_expand): Convert sindex() call to strstr().
2691 This means we no longer need to track the TLEN value so remove that.
2692 (func_findstring): Convert sindex() to strstr().
2693 * commands.c (chop_commands): Convert sindex() calls to strstr().
2694 Suggested by: Markus Mauhart <qwe123@chello.at>.
2696 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2697 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2698 If SHELL is set to CMD.EXE then assume it's batch-mode and
2699 non-unixy. I wrote the code differently from the patch, though,
2700 to make it safer. This also resolves bug #9174.
2702 2004-09-20 Paul D. Smith <psmith@gnu.org>
2704 * expand.c (variable_expand_string): Modify to invoke
2705 patsubst_expand() instead of subst_expand(); the latter didn't
2706 handle suffix patterns correctly.
2707 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2708 was used only from variable_expand_string() and is no longer used
2710 (func_subst): Ditto, on call to subst_expand().
2711 (patsubst_expand): Require the percent pointers to point to the
2712 character after the %, not to the % itself.
2713 * read.c (record_files): New call criteria for patsubst_expand().
2714 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2715 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2717 2004-09-19 Paul D. Smith <psmith@gnu.org>
2719 * function.c (subst_expand): Fix a check in by_word: look for a
2720 previous blank if we're beyond the beginning of the string, not
2721 the beginning of the word.
2722 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2724 2004-05-16 Paul D. Smith <psmith@gnu.org>
2726 * remake.c (update_goal_chain): Change the argument specifying
2727 whether we're rebuilding makefiles to be a global variable,
2728 REBUILDING_MAKEFILES.
2729 (complain): Extract the code that complains about no rules to make
2730 a target into a separate function.
2731 (update_file_1): If we tried to rebuild a file during the makefile
2732 rebuild phase and it was dontcare, then no message was printed.
2733 If we then try to build the same file during the normal build,
2734 print a message this time.
2735 (remake_file): Don't complain about un-remake-able files when
2736 we're rebuilding makefiles.
2738 2004-05-11 Paul D. Smith <psmith@gnu.org>
2740 * job.c (construct_command_argv_internal): OS/2 patches from
2741 Andreas Buening <andreas.buening@nexgo.de>.
2743 2004-05-10 Paul D. Smith <psmith@gnu.org>
2745 * remake.c (update_file): Don't walk the double-colon chain unless
2746 this is a double-colon rule. Fix suggested by Boris Kolpackov
2747 <boris@kolpackov.net>.
2749 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2750 * readme.vms: New section describing OpenVMS support and issues.
2751 * default.c (default_variables): Add support for IA64.
2752 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2753 without some privilege aborts make with the error
2754 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2755 pressing Ctrl+Y and the input device is no terminal. The change
2756 catches this error and just continues.
2758 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2760 2004-04-25 Paul D. Smith <psmith@gnu.org>
2762 * commands.c (set_file_variables): Set $< properly in the face of
2763 order-only prerequisites.
2764 Patch from Boris Kolpackov <boris@kolpackov.net>
2766 2004-04-21 Bob Byrnes <byrnes@curl.com>
2768 * main.c (main): Notice failures to remake makefiles.
2770 2004-03-28 Paul D. Smith <psmith@gnu.org>
2772 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2774 * job.c: No default shell for RISC OS.
2775 (load_too_high): Hard-code the return to 1.
2776 (construct_command_argv_internal): No sh_chars or sh_cmds.
2777 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2779 2004-03-20 Paul D. Smith <psmith@gnu.org>
2781 * variable.c (do_variable_definition): Don't append from the
2782 global set if a previous non-appending target-specific variable
2783 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2786 * expand.c (reference_variable): Don't give up on variables with
2787 no value that have the target-specific append flag set: they might
2788 have a value after all. Reported by Oliver Schmidt
2789 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2790 <nikulin@dx1cmd.inp.nsk.su>.
2792 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2793 refer to absolute pathnames in directories that don't exist: some
2794 portion of the makefile could create those directories before we
2795 match the pattern. Fixes bugs #775 and #108.
2797 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2799 * main.c (main): Free makefile_mtimes if we have any.
2800 * README.W32.template: Update documentation for the current status
2801 of the MS-Windows port.
2802 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2803 environment variable is sometimes already defined which causes the
2805 * main.c (debug_signal_handler): Only define this function if
2806 SIGUSR1 is available.
2808 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2810 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2811 * README.OS2.template: Documentation updates.
2812 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2813 link line for safety.
2814 * maintMakefile (build.sh.in): Remove an extraneous ")".
2815 * job.c (child_execute_job): Close saved FDs.
2816 * job.c (exec_command) [OS/2]: exec_command(): If the command
2817 can't be exec'ed and if the shell is not Unix-sh, then try again
2818 with argv = { "cmd", "/c", ... }. Normally, this code is never
2819 reached for the cmd shell unless the command really doesn't exist.
2820 (construct_command_argv_internal) [OS/2]: The code for cmd
2821 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2822 The CMD builtin commands are case insensitive so use strcasecmp().
2824 2004-03-19 Paul D. Smith <psmith@gnu.org>
2826 * read.c (do_define): Re-order line counter increment so the count
2827 is accurate (we were losing one line per define). Reported by
2828 Dave Yost <Dave@Yost.com>.
2830 2004-03-06 Paul D. Smith <psmith@gnu.org>
2832 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2834 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2835 * misc.c (message,error,fatal): Ditto.
2836 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2837 * config.h.W32.template: Ditto.
2838 * config.h-vms.template: Ditto.
2839 * config.ami.template: Ditto.
2841 2004-03-04 Paul D. Smith <psmith@gnu.org>
2843 * README.template: Add a note about broken /bin/sh on SunOS
2844 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2846 * misc.c (message, error, fatal): Don't use "..." if we're using
2847 varargs. ansi2knr should handle this but it doesn't work: it
2848 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2849 done. On many systems (SunOS for example) va_dcl is a #define.
2850 So, force the use of the non-"..." version on pre-ANSI compilers.
2852 * maintMakefile (sign-dist): Create some rules to help automate
2853 the new GNU ftp upload method.
2855 2004-02-24 Paul D. Smith <psmith@gnu.org>
2857 * config.h.W32.template: Add HAVE_STDARG_H
2858 * config.h-vms.template: Ditto.
2859 * config.ami.template: Ditto.
2861 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2863 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2864 * build_w32.bat: Remove extra "+".
2866 2004-02-23 Paul D. Smith <psmith@gnu.org>
2868 * make.h: Create an UNUSED macro to mark unused parameters.
2869 * (many): Clean up warnings by applying UNUSED, fixing
2870 signed/unsigned incompatibilities, etc.
2872 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2874 * filedef.h: Name the command_state enumeration.
2875 * file.c (set_command_state): Use the enumeration in the function
2878 * configure.in: Explicitly set SET_MAKE to empty, to disable
2879 MAKE=make even when no make already exists. Fix bug #3823.
2881 2004-02-22 Paul D. Smith <psmith@gnu.org>
2883 * maintMakefile: Perl script to clean up all non-CVS files. Use
2884 it on all the subdirectories for the cvs-clean target.
2886 * main.c (decode_switches): Require non-empty strings for all our
2887 string command-line options. Fixes Debian bug # 164165.
2889 * configure.in: Check for stdarg.h and varargs.h.
2890 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2891 for printing messages.
2892 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2897 A number of patches for OS/2 support from Andreas Buening
2898 <andreas.buening@nexgo.de>:
2900 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2901 disable the SIGCHLD handler.
2902 (reap_children) [OS/2]: Remove special handling of job_rfd.
2903 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2904 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2905 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2906 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2907 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2910 2004-02-21 Paul D. Smith <psmith@gnu.org>
2912 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2913 <mail@kristov.de> reports that if process_begin() fails we don't
2914 handle the error condition correctly in all cases.
2915 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2916 to have a newline on the message.
2918 * job.c (construct_command_argv_internal): Add "test" to UNIX
2919 sh_cmds[]. Fixes Savannah bug # 7606.
2921 2004-02-04 Paul D. Smith <psmith@gnu.org>
2923 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2924 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2925 Hartmut Becker <Hartmut.Becker@hp.com>.
2927 2004-01-21 Paul D. Smith <psmith@gnu.org>
2929 * job.c (load_too_high): Implement an algorithm to control the
2930 "thundering herd" problem when using -l to control job creation
2931 via the load average. The system only recomputes the load once a
2932 second but we can start many jobs in a second. To solve this we
2933 keep track of the number of jobs started in the last second and
2934 apply a weight to try to guess what a correct load would be.
2935 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2936 Also fixes bug #4693.
2937 (reap_children): Decrease the job count for this second.
2938 (start_job_command): Increase the job count for this second.
2940 * read.c (conditional_line): Expand the text after ifn?def before
2941 checking to see if it's a single word. Fixes bug #7257.
2943 2004-01-09 Paul D. Smith <psmith@gnu.org>
2945 * file.c (print_file): Recurse to print all targets in
2946 double-colon rules. Fixes bug #4518, reported (with patch) by
2947 Andrew Chatham <chatham@google.com>.
2949 2004-01-07 Paul D. Smith <psmith@gnu.org>
2951 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2952 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2953 AC_FUNC_SETVBUF_REVERSED.
2955 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2956 (MAKE Variable): Fix Savannah bug #4898.
2958 * job.c (construct_command_argv_internal): Add "!" to the list of
2959 shell escape chars. POSIX sh allows it to appear before a
2960 command, to negate the exit code. Fixes bug #6404.
2962 * implicit.c (pattern_search): When matching an implicit rule,
2963 remember which dependencies have the ignore_mtime flag set.
2964 Original fix provided in Savannah patch #2349, by Benoit
2965 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2967 2003-11-22 Paul D. Smith <psmith@gnu.org>
2969 * README.W32.template (Outputs): Clarification on -j with
2970 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2973 2003-11-02 Paul D. Smith <psmith@gnu.org>
2975 * function.c (func_if): Strip all the trailing whitespace from the
2976 condition, then don't expand it. Fixed bug # 5798.
2978 * expand.c (recursively_expand_for_file): If we're expanding a
2979 variable with no file context, then use the variable's context.
2982 2003-10-21 Paul D. Smith <psmith@gnu.org>
2984 * main.c (log_working_directory): Add newlines to printf()s.
2986 * README.cvs: Add a note to ignore warnings during autoreconf.
2988 * maintMakefile (po_repo): Set a new URL for PO file updates.
2989 (get-config/config.guess get-config/config.sub): Get these files
2990 from the Savannah config project instead of ftp.gnu.org.
2992 2003-10-05 Paul Eggert <eggert@twinsun.com>
2994 * main.c (main): Avoid potential subscript error if environ has
2997 2003-08-22 Paul D. Smith <psmith@gnu.org>
2999 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3000 systems which don't yet implement the C89 standard :-/.
3002 2003-07-18 Paul D. Smith <psmith@gnu.org>
3004 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3005 [WINDOWS32]: Initialize hash.
3007 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3009 * dir.c (read_dirstream): Provide a workaround for broken versions of
3010 the MinGW dirent structure.
3012 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3014 * w32/include/dirent.h: Add __MINGW32__ filter.
3016 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3018 * make.h: Add global declaration of *make_host.
3019 * main.c (print_usage): Remove local declaration of *make_host.
3020 (print_version): Display "This program built for ..." after Copyright
3023 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3025 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3026 execution of "makeinfo --html make.texi".
3028 2003-04-30 Paul D. Smith <psmith@gnu.org>
3030 * build.template: Make some changes to maybe allow this script to
3031 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3033 * README.OS2.template: New file for OS/2 support. Original
3034 contributed by Andreas Buening.
3035 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3038 2003-04-19 Paul D. Smith <psmith@gnu.org>
3040 Fix bug #1405: allow a target to match multiple pattern-specific
3043 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3044 variable.c, where they've always belonged.
3045 * rule.h: Move the prototypes and struct pattern_var as well.
3046 * variable.c (initialize_file_variables): Invoke
3047 lookup_pattern_var() in a loop, until no more matches are found.
3048 If a match is found, create a new variable set for the target's
3049 pattern variables. Then merge the contents of each matching
3050 pattern variable set into the target's pattern variable set.
3051 (lookup_pattern_var): Change this function to be usable
3052 in a loop. It takes a starting position: if NULL, start at the
3053 beginning; if non-NULL, start with the pattern variable after that
3054 position, and return the next matching pattern.
3055 (create_pattern_var): Create a unique instance of
3056 pattern-specific variables for every definition in the makefile.
3057 Don't combine the same pattern together. This allows us to
3058 process the variable handling properly even when the same pattern
3059 is used multiple times.
3060 (parse_variable_definition): New function: break out the parsing
3061 of a variable definition line from try_variable_definition.
3062 (try_variable_definition): Call parse_variable_definition to
3064 (print_variable_data_base): Print out pattern-specific variables.
3065 * variable.h (struct variable): Remember when a variable is
3066 conditional. Also remember its flavor.
3067 (struct pattern_var): Instead of keeping a variable set, we just
3068 keep a single variable for each pattern.
3069 * read.c (record_target_var): Each pattern variable contains only a
3070 single variable, not a set, so create it properly.
3071 * doc/make.texi (Pattern-specific): Document the new behavior.
3073 2003-04-17 Paul D. Smith <psmith@gnu.org>
3075 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3076 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3077 file/directory naming rules for VMS so I can't tell whether this
3080 2003-04-09 Paul D. Smith <psmith@gnu.org>
3082 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3083 DOS-style pathnames: backslash separators and drive specifiers.
3085 2003-03-28 Paul D. Smith <psmith@gnu.org>
3087 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3088 the intermediate flag on all targets. Fixes bug #2515.
3090 2003-03-24 Paul D. Smith <psmith@gnu.org>
3092 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3093 Upgrade to autoconf 2.57 and automake 1.7.3.
3095 * job.c: More OS/2 changes from Andreas Buening.
3097 * file.c (print_file): Fix variable initialization.
3100 * remake.c (notice_finished_file):
3102 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3103 some calls (like readdir()) return NULL in valid situations
3104 without resetting errno. Fixes bug #2846.
3106 2003-02-25 Paul D. Smith <psmith@gnu.org>
3108 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3110 * job.c (_is_unixy_shell) [OS/2]: New function.
3111 Set default shell to /bin/sh.
3112 (reap_children): Close the job_rfd pipe here since we don't use a
3114 (set_child_handler_action_flags): define this to empty on OS/2.
3115 (start_job_command): Close the jobserver pipe and use
3116 child_execute_job() instead of fork/exec.
3117 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3118 rather than exec'ing, then reconfigure stdin/stdout.
3119 (exec_command): Rewrite to use spawn instead of exec. Return the
3122 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3123 in DOS. Handle the TEMP environment variable as in DOS. Don't
3124 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3125 use -j in DOS mode. Use child_execute_job() instead of
3128 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3131 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3132 prototypes that return values.
3134 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3136 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3137 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3139 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3142 2003-02-24 Paul D. Smith <psmith@gnu.org>
3144 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3145 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3146 (child_execute_job) [VMS]: Handle error status properly.
3147 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3149 * function.c (func_shell): Use EINTRLOOP() while reading from the
3150 subshell pipe (Fixes bug #2502).
3151 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3153 * main.c (main): Ditto.
3155 2003-01-30 Paul D. Smith <psmith@gnu.org>
3157 * read.c (eval): eval() was not fully reentrant, because the
3158 collapsed buffer was static. Change it to be an automatic
3159 variable so that eval() can be invoked recursively.
3161 (eval): Apply patch # 1022: fix memory reference error on long
3162 target-specific variable lines.
3163 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3165 * function.c (check_numeric): Combine the is_numeric() function
3166 into this function, since it's only called from one place.
3167 Constify this function. Have it print the incorrect string in the
3168 error message. Fixes bug #2407.
3169 (strip_whitespace): Constify.
3170 (func_if): Constify.
3171 * expand.c (expand_argument): Constify.
3173 2003-01-29 Paul D. Smith <psmith@gnu.org>
3175 Fix bug # 2169, also reported by other people on various systems.
3177 * make.h: Some systems, such as Solaris and PTX, do not fully
3178 implement POSIX-compliant SA_RESTART functionality; important
3179 system calls like stat() and readdir() can still fail with EINTR
3180 even if SA_RESTART has been set on the signal handler. So,
3181 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3182 EINTR for system calls which return -1 or 0 (NULL), respectively,
3184 Also, remove the old atomic_stat()/atomic_readdir() and
3185 HAVE_BROKEN_RESTART handling.
3187 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3189 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3190 * remake.c (touch_file): Ditto.
3192 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3193 * read.c (construct_include_path): Ditto.
3194 * remake.c (name_mtime): Ditto.
3195 * vpath.c (selective_vpath_search): Ditto.
3196 * dir.c (find_directory): Ditto.
3197 (local_stat): Ditto.
3198 (find_directory): Use ENULLLOOP() to wrap opendir().
3199 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3201 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3202 atomic_readdir() handling.
3204 2003-01-22 Paul D. Smith <psmith@gnu.org>
3206 * function.c (func_call): Fix Bug #1744. If we're inside a
3207 recursive invocation of $(call ...), mask any of the outer
3208 invocation's arguments that aren't used by this one, so that this
3209 invocation doesn't "inherit" them accidentally.
3211 2002-12-05 Paul D. Smith <psmith@gnu.org>
3213 * function.c (subst_expand): Valery Khamenia reported a
3214 pathological performance hit when doing substitutions on very
3215 large values with lots of words: turns out we were invoking
3216 strlen() a ridiculous number of times. Instead of having each
3217 call to sindex() call strlen() again, keep track of how much of
3218 the text we've seen and pass the length to sindex().
3220 2002-11-19 Paul D. Smith <psmith@gnu.org>
3222 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3225 2002-11-16 Paul D. Smith <psmith@gnu.org>
3227 * NMakefile.template (OBJS): Add hash.c object file.
3228 * SMakefile.template (srcs): Ditto.
3229 * Makefile.ami (objs): Ditto.
3230 * build_w32.bat: Ditto.
3232 * Makefile.DOS.template: Remove extra dependencies.
3234 2002-10-25 Paul D. Smith <psmith@gnu.org>
3236 * expand.c (install_variable_buffer): New function. Install a new
3237 variable_buffer context and return the previous one.
3238 (restore_variable_buffer): New function. Free the current
3239 variable_buffer context and put a previously saved one back.
3240 * variable.h: Prototypes for {install,restore}_variable_buffer.
3241 * function.c (func_eval): Push a new variable_buffer context
3242 before we eval, then restore the old one when we're done.
3245 * read.c (install_conditionals): New function. Install a new
3246 conditional context and return the previous one.
3247 (restore_conditionals): New function. Free the current
3248 conditional context and put a previously saved one back.
3249 (eval): Use the {install,restore}_conditionals for "include"
3251 (eval_buffer): Use {install,restore}_conditionals to preserve the
3252 present conditional state before we evaluate the buffer.
3255 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3257 (Recursion): Add a variable index entry for CURDIR.
3259 * README.cvs: Update to appropriate versions.
3260 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3261 don't need to copy loadavg.c: automake is smart enough to create
3262 it for me. Still have a bug in automake related to ansi2knr tho.
3264 2002-10-14 Paul D. Smith <psmith@gnu.org>
3266 * remake.c (notice_finished_file): Only touch targets if they have
3267 at least one command (as per POSIX). Resolve Bug #1418.
3269 * *.c: Convert to using ANSI C-style function definitions.
3270 * Makefile.am: Enable the ansi2knr feature of automake.
3271 * configure.in: ditto.
3273 2002-10-13 Paul D. Smith <psmith@gnu.org>
3275 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3276 for automatic variable values like $^, etc. In the case of very
3277 large lists of prerequisites this causes problems. Instead reuse
3278 a static buffer (resizeable) for each variable.
3280 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3281 target-specific variable definitions. Check for it and set an
3283 (record_target_var): Set the export field to v_export if the
3284 "exported" flag is set.
3285 * doc/make.texi (Target-specific): Document the ability to use
3288 * doc/make.texi: Change the name of the section on automatic
3289 variables from "Automatic" to "Automatic Variables". Added text
3290 clarifying the scope of automatic variables.
3292 2002-10-04 Paul D. Smith <psmith@gnu.org>
3294 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3296 (record_files): Ditto.
3298 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3299 the search for the '=' to only within the enclosing parens.
3301 2002-10-03 Paul D. Smith <psmith@gnu.org>
3303 Version 3.80 released.
3305 * dir.c: Change hash functions to use K&R function definition style.
3306 * function.c: Ditto.
3308 * variable.c: Ditto.
3310 Update to automake 1.7.
3312 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3313 (pdf): Remove this target as automake now provides one.
3315 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3317 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3319 * makefile.com: Updates for GNU make 3.80.
3320 * makefile.vms: Ditto.
3322 2002-09-23 Paul D. Smith <psmith@gnu.org>
3324 * read.c (enum make_word_type): Remove w_comment.
3325 (get_next_mword): Don't treat comment characters as special; where
3326 this function is used we will never see a comment (it's stripped
3327 before we get here) and treating comments specially means that
3328 targets like "foo\#bar" aren't handled properly.
3330 2002-09-18 Paul D. Smith <psmith@gnu.org>
3332 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3334 * read.c (eval): Expansion of arguments to export/unexport was
3335 ignoring all arguments after the first one. Change the algorithm
3336 to expand the whole line once, then parse the results.
3338 2002-09-17 Paul D. Smith <psmith@gnu.org>
3340 Fix Bug #940 (plus another bug I found while looking at this):
3342 * read.c (record_target_var): enter_file() will add a new entry if
3343 it's a double-colon target: we don't want to do that in this
3344 situation. Invoke lookup_file() and only enter_file() if it does
3345 not already exist. If the file we get back is a double-colon then
3346 add this variable to the "root" double-colon target.
3348 * variable.c (initialize_file_variables): If this file is a
3349 double-colon target but is not the "root" target, then initialize
3350 the root and make the root's variable list the parent of our
3353 2002-09-13 Paul D. Smith <psmith@gnu.org>
3355 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3357 * hash.c (round_up_2): Get rid of a warning.
3359 2002-09-12 Paul D. Smith <psmith@gnu.org>
3361 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3362 so it doesn't complain about getloadavg.c.
3364 * commands.c (set_file_variables): Make sure we always alloca() at
3365 least 1 character for the value of $? (for '\0').
3367 2002-09-11 Paul D. Smith <psmith@gnu.org>
3369 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3370 macro to use RESULT instead of the incorrect _RESULT_.
3372 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3373 and atomic_readdir(). We need to #include dirent.h to get this to
3375 * misc.c (atomic_readdir): Fix typos.
3377 2002-09-10 Paul D. Smith <psmith@gnu.org>
3379 * read.c (eval): Expand variable lists given to export and
3380 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3381 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3383 * doc/make.texi (Variables/Recursion): Document this.
3384 (Conditional Syntax): And here.
3386 2002-09-09 Paul D. Smith <psmith@gnu.org>
3388 * configure.in: Check for memmove().
3390 2002-09-07 Paul D. Smith <psmith@gnu.org>
3392 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3393 Michael Sterrett <msterret@coat.com> reports that while it has
3394 SA_RESTART, it does not work properly.
3396 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3397 that invokes stat() and loops to do it again if it returns EINTR.
3398 (atomic_readdir): Ditto, with readdir().
3400 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3401 and readdir() to atomic_stat() and atomic_readdir().
3403 2002-09-04 Paul D. Smith <psmith@gnu.org>
3405 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3406 reports that GNU make sometimes doesn't recognize that targets can
3407 be made, when directories can be created as prerequisites. He
3408 reports that changing the order of predicates in the DEP->changed
3409 flag test so that lookup_file() is always performed, solves this
3412 2002-08-08 Paul D. Smith <psmith@gnu.org>
3414 * configure.in: Require a newer version of gettext.
3416 * misc.c (perror_with_name): Translate the format string (for
3417 right-to-left language support).
3418 (pfatal_with_name): Ditto.
3420 * main.c: Create a static array of strings to store the usage
3421 text. This is done to facilitate translations.
3422 (struct command_switch): Remove argdesc and description fields.
3423 (switches): Remove values for obsolete fields.
3424 (print_usage): Print each element of the usage array.
3426 * hash.c: Change function definitions to be K&R style.
3428 2002-08-02 Paul D. Smith <psmith@gnu.org>
3430 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3431 this one because it's too hard to get right. We'll look at it for
3433 * main.c (main): Don't create the .TARGETS variable.
3434 * variable.c (handle_special_var): Don't handle .TARGETS.
3436 2002-08-01 Paul D. Smith <psmith@gnu.org>
3438 * main.c (switches): Add a new option, -B (--always-make). If
3439 specified, make will rebuild all targets that it encounters even
3440 if they don't appear to be out of date.
3441 (always_make_flag): New flag.
3442 * make.h: Extern always_make_flag.
3443 * remake.c (update_file_1): Check always_make_flag; if it's set we
3444 will always rebuild any target we can, even if none of its
3445 prerequisites are newer.
3448 * doc/make.texi (Shell Function): Make it clear that make
3449 variables marked as "export" are not passed to instances of the
3452 Add new introspection variable .VARIABLES and .TARGETS.
3454 * variable.c (handle_special_var): New function. If the variable
3455 reference passed in is "special" (.VARIABLES or .TARGETS),
3456 calculate the new value if necessary. .VARIABLES is handled here:
3457 walk through the hash of defined variables and construct a value
3458 which is a list of the names. .TARGETS is handled by
3459 build_target_list().
3460 (lookup_variable): Invoke handle_special_var().
3461 * file.c (build_target_list): Walk through the hask of known files
3462 and construct a list of the names of all the ones marked as
3464 * main.c (main): Initialize them to empty (and as simple variables).
3465 * doc/make.texi (Special Variables): Document them.
3466 * NEWS: Mention them.
3468 * variable.h (struct variable): Add a new flag "exportable" which
3469 is true if the variable name is valid for export.
3470 * variable.c (define_variable_in_set): Set "exportable" when a new
3471 variable is defined.
3472 (target_environment): Use the "exportable" flag instead of
3473 re-checking the name here... an efficiency improvement.
3475 2002-07-31 Paul D. Smith <psmith@gnu.org>
3477 * config.h-vms.template: Updates to build on VMS. Thanks to
3478 Brian_Benning@aksteel.com for helping verify the build.
3479 * makefile.com: Build the new hash.c file.
3480 * hash.h: Use strcpmi(), not stricmp(), in the
3481 HAVE_CASE_INSENSITIVE_FS case.
3483 2002-07-30 Paul D. Smith <psmith@gnu.org>
3485 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3486 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3487 Reported by <Brian_Benning@aksteel.com>.
3489 2002-07-10 Paul D. Smith <psmith@gnu.org>
3491 * variable.c (pop_variable_scope): Remove variable made unused by
3492 new hash infrastructure.
3493 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3494 comparisons as well as name comparisons.
3495 * variable.h: Add a prototype for new hash_init_function_table().
3496 * file.c (lookup_file): Remove variables made unused by new hash
3498 * dir.c (directory_contents_hash_2): Missing return of hash value.
3499 (dir_contents_file_exists_p): Remove variables made unused by new
3500 hash infrastructure.
3503 Installed Greg McGary's integration of the hash functions from the
3504 GNU id-utils package:
3506 2002-07-10 Greg McGary <greg@mcgary.org>
3508 * scripts/functions/filter-out: Add literals to to the
3509 pattern space in order to add complexity, and trigger
3510 use of an internal hash table. Fix documentation strings.
3511 * scripts/targets/INTERMEDIATE: Reverse order of files
3512 passed to expected `rm' command.
3514 2002-07-10 Greg McGary <greg@mcgary.org>

3606 2002-07-10 Paul D. Smith <psmith@gnu.org>
3608 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3609 prerequisite list. A real SysV make will expand the entire
3610 prerequisites list _twice_: we don't do that as it's a big
3611 backward-compatibility problem. We only replace those specific
3614 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3615 references left in the list of prerequisites. Check for .POSIX as
3616 we record targets, so we can disable non-POSIX behavior while
3617 reading makefiles as well as running them.
3618 (eval): Check the prerequisite list to see if we have anything
3619 that looks like a SysV prerequisite variable reference.
3621 2002-07-09 Paul D. Smith <psmith@gnu.org>
3623 * doc/make.texi (Prerequisite Types): Add a new section describing
3624 order-only prerequisites.
3626 * read.c (uniquize_deps): If we have the same file as both a
3627 normal and order-only prereq, get rid of the order-only prereq,
3628 since the normal one supersedes it.
3630 2002-07-08 Paul D. Smith <psmith@gnu.org>
3632 * AUTHORS: Added Greg McGary to the AUTHORS file.
3633 * NEWS: Blurbed order-only prerequisites.
3634 * file.c (print_file): Show order-only deps properly when printing
3637 * maintMakefile: Add "update" targets for wget'ing the latest
3638 versions of various external files. Taken from Makefile.maint in
3641 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3642 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3644 2002-07-07 Paul D. Smith <psmith@gnu.org>
3646 * po/*.po: Remove. We'll use wget to retrieve them at release
3649 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3650 rather than a shell you get an exception. Make sure we look up
3651 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3653 * remake.c (notice_finished_file): Fix handling of -t flag.
3654 Patch provided by Henning Makholm <henning@makholm.net>.
3656 * implicit.c (pattern_search): Some systems apparently run short
3657 of stack space, and using alloca() in this function caused an
3658 overrun. I modified it to use xmalloc() on the two variables
3659 which seemed like they might get large. Fixes Bug #476.
3661 * main.c (print_version): Update copyright notice to conform with
3663 (print_usage): Update help output.
3665 * function.c (func_eval): Create a new make function, $(eval
3666 ...). Expand the arguments, put them into a buffer, then invoke
3667 eval_buffer() on the resulting string.
3668 (func_quote): Create a new function, $(quote VARNAME). Inserts
3669 the value of the variable VARNAME without expanding it any
3672 * read.c (struct ebuffer): Change the linebuffer structure to an
3673 "eval buffer", which can be either a file or a buffer.
3674 (eval_makefile): Move the code in the old read_makefile() which
3675 located a makefile into here: create a struct ebuffer with that
3676 information. Have it invoke the new function eval() with that
3678 (eval_buffer): Create a new function that creates a struct ebuffer
3679 that holds a string buffer instead of a file. Have it invoke
3680 eval() with that ebuffer.
3681 (eval): New function that contains the guts of the old
3682 read_makefile() function: this function parses makefiles. Obtains
3683 data to parse from the provided ebuffer. Some modifications to
3684 make the flow of the function cleaner and clearer. Still could
3685 use some work here...
3686 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3687 contents of the define/endef variable from the ebuffer.
3688 (readstring): Read the next line from a string-style ebuffer.
3689 (readline): Read the next line from an ebuffer. If it's a string
3690 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3693 * dep.h (eval_buffer): Prototype eval_buffer();
3695 * variable.c (do_variable_definition): Make sure that all
3696 non-target-specific variables are registered in the global set.
3697 If we're invoked from an $(eval ...) we might be inside a $(call
3698 ...) or other function which has pushed a variable scope; we still
3699 want to define our variables from evaluated makefile code in the
3702 2002-07-03 Greg McGary <greg@mcgary.org>
3704 * dep.h (struct dep) [ignore_mtime]: New member.
3705 [changed]: convert to a bitfield.
3706 * implicit.c (pattern_search): Zero ignore_mtime.
3707 * main.c (main, handle_non_switch_argument): Likewise.
3708 * rule.c (convert_suffix_rule): Likewise.
3709 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3710 (read_makefile): Parse '|' in prerequisite list.
3711 (uniquize_deps): Consider ignore_mtime when comparing deps.
3712 * remake.c (update_file_1, check_dep): Don't force remake for
3713 dependencies that have d->ignore_mtime.
3714 * commands.c (FILE_LIST_SEPARATOR): New constant.
3715 (set_file_variables): Don't include a
3716 prerequisite in $+, $^ or $? if d->ignore_mtime.
3719 2002-06-18 Paul D. Smith <psmith@gnu.org>
3721 * make.texinfo: Updates for next revision. New date/rev/etc.
3722 Recreate all Info menus. Change license on the manual to the GNU
3723 Free Documentation License. A number of typos.
3724 (Variables Simplify): Don't use "-" before it's defined.
3725 (Automatic Prerequisites): Rewrite the target example to work
3726 properly if the compile fails. Remove incorrect comments about
3727 how "set -e" behaves.
3728 (Text Functions): Move the "word", "wordlist", "words", and
3729 "firstword" functions here, from "File Name Functions".
3730 * make-stds.texi: Update from latest GNU version.
3731 * fdl.texi: (created) Import the latest GNU version.
3733 2002-06-06 Paul D. Smith <psmith@gnu.org>
3735 * variable.c (do_variable_definition): New function: extract the
3736 part of try_variable_definition() that actually sets the value
3737 into a separate function.
3738 (try_variable_definition): Call do_variable_definition() after
3739 parsing the variable definition string.
3740 (define_variable_in_set): Make the name argument const.
3742 * variable.h (enum variable_flavor): Make public.
3743 (do_variable_definition): Create prototype.
3745 * read.c (read_all_makefiles): Create a new built-in variable,
3747 (read_makefile): Add each makefile read in to this variable value.
3749 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3751 * Makefile.DOS.template: Tweak according to changes in the
3752 distribution. Add back the dependencies of *.o files.
3754 * configh.dos.template: Synchronize with config.h.in.
3756 2002-05-09 Paul D. Smith <psmith@gnu.org>
3758 * file.c (file_timestamp_now): Use K&R function declaration.
3760 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3761 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3762 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3763 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3764 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3765 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3766 nlist.n_name is a pointer rather than an array.
3768 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3769 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3770 * configure.in: Use it instead of the old version.
3772 * main.c (main): Prefer setvbuf() to setlinebuf().
3774 2002-05-08 Paul D. Smith <psmith@gnu.org>
3776 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3777 (loadavg_LDADD): Ditto.
3779 2002-04-29 Paul D. Smith <psmith@gnu.org>
3781 * expand.c (recursively_expand_for_file): Rename
3782 recursively_expand() to recursively_expand_for_file() and provide
3783 an extra argument, struct file. If the argument is provided, set
3784 the variable scope to that of the file before expanding.
3785 * variable.h (recursively_expand): Make this a macro that invokes
3786 recursively_expand_for_file() with a NULL file pointer.
3787 * variable.c (target_environment): Call the renamed function and
3788 provide the current file context.
3789 Fixes Debian bug #144306.
3791 2002-04-28 Paul D. Smith <psmith@gnu.org>
3793 Allow $(call ...) user-defined variables to be self-referencing
3794 without throwing an error. Allows implementation of transitive
3795 closures, among other possibly useful things.
3796 Requested by: Philip Guenther <guenther@sendmail.com>
3798 * variable.h (struct variable): Add a new field: exp_count, and
3799 new macros to hold its size and maximum value.
3800 (warn_undefined): Make this a macro.
3801 * variable.c (define_variable_in_set): Initialize it.
3802 * expand.c (recursively_expand): If we detect recursive expansion
3803 of a variable, check the exp_count field. If it's greater than 0
3804 allow the recursion and decrement the count.
3805 (warn_undefined): Remove this (now a macro in variable.h).
3806 * function.c (func_call): Before we expand the user-defined
3807 function, modify its exp_count field to contain the maximum
3808 number of recursive calls we'll allow. After the call, reset it
3811 2002-04-21 Paul D. Smith <psmith@gnu.org>
3813 Modified to use latest autoconf (2.53), automake (1.6.1), and
3814 gettext (0.11.1). We're using gettext's new "external" support,
3815 to avoid including libintl source with GNU make.
3817 * README.cvs: New file. Explain how to build GNU make from CVS.
3819 * configure.in: Modify checking for the system glob library.
3820 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3821 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3822 etc. will manage it correctly). Set an automake conditional
3823 USE_LOCAL_GLOB to decide whether to compile the glob library.
3825 * getloadavg.c (main): Include make.h in the "TEST" program to
3828 * Makefile.am: Remove special rules for loadavg. Replace them
3829 with Automake capabilities for building extra programs.
3831 * signame.c: This file does nothing if the system provide
3832 strsignal(). If not, it implements strsignal(). If the system
3833 doesn't define sys_siglist, then we make our own; otherwise we use
3835 * signame.h: Removed.
3837 * main.c (main): No need to invoke signame_init(). Update copyright.
3839 * ABOUT-NLS: Removed.
3840 * gettext.c: Removed.
3841 * gettext.h: Get a simplified copy from the gettext package.
3843 * i18n/*.po: Moved to po/.
3846 * config/*: Created. Contains package configuration helper files.
3847 * config.guess, config.sub: Moved to config directory.
3849 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3850 Rework to use new-style autoconf features. Use the "external"
3851 mode for gettext. Make the build.sh config file conditional on
3852 whether build.sh.in exists, to avoid autoconf errors.
3853 * acinclude.m4: Removed almost all macros as being obsolete.
3854 Rewrote remaining macros to use AC_DEFINE.
3855 * acconfig.h: Removed.
3857 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3858 conditional to handle customs support. Remove special handling
3861 2002-04-20 Paul D. Smith <psmith@gnu.org>
3863 * function.c (func_call): Don't mark the argument variables $1,
3864 etc. as recursive. They've already been fully expanded so
3865 there's no need to do it again, and doing so strips escaped $'s.
3866 Reported by Sebastian Glita <glseba@yahoo.com>.
3868 * remake.c (notice_finished_file): Walk through double-colon
3869 entries via the prev field, not the next field!
3870 Reported by Greg McGary <greg@mcgary.org>.
3872 * main.c (main): If the user specifies -q and asks for a specific
3873 target which is a makefile, we got an assert. In that case it
3874 turns out we should continue normally instead.
3876 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3878 * i18n/he.po: Installed a new translation.
3880 2002-01-07 Paul D. Smith <psmith@gnu.org>
3882 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3884 2001-12-04 Paul D. Smith <psmith@gnu.org>
3886 * i18n/ja.po: Installed an updated translation.
3888 2001-09-06 Paul Eggert <eggert@twinsun.com>
3890 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3891 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3893 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3895 (main): Get rid of any avoidable limit on stack size.
3897 2001-09-04 Paul D. Smith <psmith@gnu.org>
3899 * i18n/da.po: Installed an updated translation.
3901 2001-08-03 Paul D. Smith <psmith@gnu.org>
3903 * i18n/fr.po: Installed an updated translation.
3904 Resolves Debian bug #106720.
3906 2001-06-13 Paul D. Smith <psmith@gnu.org>
3908 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3911 2001-06-11 Paul D. Smith <psmith@gnu.org>
3913 * i18n/ko.po: Installed a new translation.
3915 2001-05-06 Paul D. Smith <psmith@gnu.org>
3917 Modify the EINTR handling.
3919 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3920 the way in which we manage the file descriptor/signal handler race
3921 trap to be more efficient.
3923 2001-05-06 Paul Eggert <eggert@twinsun.com>
3925 Restart almost all system calls that are interrupted, instead
3926 of worrying about EINTR. The lone exception is the read() for
3929 * configure.in (HAVE_SA_RESTART): New macro.
3930 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3931 * main.c (main): Use SA_RESTART instead of the old,
3932 nonstandard SA_INTERRUPT.
3934 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3935 * main.c (bsd_signal): New function or macro,
3936 if the implementation doesn't supply it.
3937 (The bsd_signal function will be in POSIX 1003.1-200x.)
3938 (HANDLESIG): Remove.
3939 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3941 * make.h (EINTR_SET): Remove.
3942 (SA_RESTART): New macro.
3944 * arscan.c (ar_member_touch): Don't worry about EINTR.
3945 * function.c (func_shell): Likewise.
3946 * job.c (reap_children, free_child, new_job): Likewise.
3947 * main.c (main): Likewise.
3948 * remake.c (touch_file, name_mtime): Likewise.
3950 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3951 if fstat failed with errno!=EINTR, the error was ignored.
3953 * job.c (set_child_handler_action_flags): New function.
3954 (new_job): Use it to temporarily clear the SIGCHLD action flags
3955 while reading the token.
3957 2001-05-02 Paul D. Smith <psmith@gnu.org>
3959 * job.c (start_job_command): Don't add define/endef per-line flags
3960 to the top-level flags setting.
3962 2001-04-03 Paul D. Smith <psmith@gnu.org>
3964 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3965 bit on error, so check for odd return values, not non-0 return
3967 (VMS_get_member_info): Calculate the timezone differences correctly.
3968 Reported by John Fowler <jfowler@nyx.net>.
3971 2001-03-14 Paul D. Smith <psmith@gnu.org>
3973 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3974 value before invoking define_variable().
3975 Reported by John Fowler <jfowler@nyx.net>.
3977 2001-02-07 Paul D. Smith <psmith@gnu.org>
3979 * read.c (record_target_var): If we reset the variable due to a
3980 command-line variable setting overriding it, turn off the "append"
3983 2001-01-17 Paul D. Smith <psmith@gnu.org>
3985 * variable.c (lookup_variable) [VMS]: When getting values from the
3986 environment, allocate enough space for the _value_ plus escapes,
3987 not enough space for the name plus escapes :-/.
3988 Reported by John Fowler <jfowler@nyx.net>.
3990 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3991 warnings that make generates, so it doesn't look like an error.
3992 Reported by Karl Berry <karl@gnu.org>.
3995 Fix for PR/2020: Rework appended target-specific variables. I'm
3996 fairly confident this algorithm is finally correct.
3998 * expand.c (allocated_variable_append): Rewrite. Instead of
3999 expanding each appended variable then adding all the expanded
4000 strings together, we append all the unexpanded values going up
4001 through the variable set contexts, then expand the final result.
4002 This behaves just like non-target-specific appended variable
4003 values, while the old way didn't in various corner cases.
4004 (variable_append): New function: recursively append the unexpanded
4005 value of a variable, walking from the outermost variable scope to
4007 * variable.c (lookup_variable): Remove the code that looked up the
4008 variable set list if the found variable was "append". We don't
4010 (lookup_variable_in_set): Make this non-static so we can use it
4012 (try_variable_definition): Use lookup_variable_in_set() rather
4013 than faking out current_variable_set_list by hand (cleanup).
4014 * variable.h: Add a prototype for the now non-static
4015 lookup_variable_in_set().
4017 2000-11-17 Paul D. Smith <psmith@gnu.org>
4019 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4020 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4021 before throwing a fit.
4023 2000-11-17 Paul D. Smith <psmith@gnu.org>
4025 * read.c (readline): CRLF calculations had a hole, if you hit the
4026 buffer grow scenario just right. Reworked the algorithm to avoid
4027 the need for len or lastlen at all. Problem description with
4028 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4030 2000-10-24 Paul D. Smith <psmith@gnu.org>
4032 * gettext.c (SWAP): Declare this with the prototype, otherwise
4033 some systems don't work (non-32-bit? Reported for Cray T3E).
4034 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4036 2000-10-05 Paul D. Smith <psmith@gnu.org>
4038 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4039 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4041 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4043 2000-09-22 Paul D. Smith <psmith@gnu.org>
4045 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4046 parts of the real gettext.h here, and we expect to really include
4047 the real gettext.h later. If we keep this #define, it's ignored.
4049 2000-09-21 Paul D. Smith <psmith@gnu.org>
4051 * main.c (log_working_directory): Rework the text to use complete
4052 sentences, to make life simpler for the translators.
4054 2000-08-29 Paul D. Smith <psmith@gnu.org>
4056 * file.c (remove_intermediates): Print a debug message before we
4057 remove intermediate files, so the user (if she uses -d) knows
4060 2000-08-21 Paul D. Smith <psmith@gnu.org>
4062 * variable.c (try_variable_definition): Change how we handle
4063 target-specific append variable defns: instead of just setting the
4064 value, expand it as an append _but_ only within the current
4065 target's context. Otherwise we lose all but the last value if the
4066 variable is appended more than once within the current target
4067 context. Fixes PR/1831.
4069 2000-08-16 Paul D. Smith <psmith@gnu.org>
4071 * function.c (func_shell): Nul-terminate the buffer before
4072 printing an exec error message (just in case it's not!).
4073 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4075 2000-07-25 Paul D. Smith <psmith@gnu.org>
4077 * job.c (construct_command_argv_internal): Add "~" to the list of
4078 sh_chars[] which disallow optimizing out the shell call.
4080 2000-07-23 Paul Eggert <eggert@twinsun.com>
4082 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4083 supersedes --disable-nsec-timestamps.
4084 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4085 * README: Remove --disable-nsec-timestamps.
4087 * filedef.h (struct file.low_resolution_time): New member.
4088 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4089 * remake.c (update_file_1):
4090 Avoid spurious rebuilds due to low resolution time stamps,
4091 generalizing the earlier code that applied only to archive members.
4092 (f_mtime): Archive members always have low resolution time stamps.
4094 * configure.in: Remove --disable-nsec-timestamps, as this has
4095 been superseded by .LOW_RESOLUTION_TIME.
4097 2000-07-23 Paul Eggert <eggert@twinsun.com>
4099 * configure.in (enable_nsec_timestamps): Renamed from
4100 make_cv_nsec_timestamps, since enable/disable options
4101 shouldn't be cached.
4103 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4104 and Paul Eggert <eggert@twinsun.com>
4106 * file.c (file_timestamp_now):
4107 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4108 so that clock_gettime is not linked unless needed.
4110 * filedef.h (FILE_TIMESTAMP_HI_RES):
4111 Remove definition; "configure" now does this.
4113 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4114 to before high resolution file timestamp check,
4115 since that check now uses uintmax_t.
4116 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4117 high resolution file timestamps.
4118 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4119 so that we don't link in clock_gettime unnecessarily.
4121 2000-07-17 Paul D. Smith <psmith@gnu.org>
4123 * i18n/ja.po: New version of the translation file.
4125 2000-07-07 Paul D. Smith <psmith@gnu.org>
4127 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4128 the offset calculation.
4129 (name_mtime): Replace EINTR test with EINTR_SET macro.
4131 2000-07-07 Paul Eggert <eggert@twinsun.com>
4135 * remake.c (update_file_1):
4136 Avoid spurious rebuilds of archive members due to their
4137 timestamp resolution being only one second.
4138 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4139 the clock's resolution being lower than file timestamps'.
4140 When warning about future timestamps, report only the discrepancy,
4141 not the absolute value of the timestamp and the current time.
4143 * file.c (file_timestamp_now): New arg RESOLUTION.
4144 * filedef.h (file_timestamp_now): Likewise.
4145 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4147 2000-07-05 Paul D. Smith <psmith@gnu.org>
4149 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4150 to listp. Fixes PR/1793.

4154 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4156 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4158 * remake.c (f_mtime): Remove unused var memtime.
4160 2000-06-25 Martin Buchholz <martin@xemacs.org>
4162 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4163 Ran spell-check on make.texinfo.
4165 2000-06-23 Paul D. Smith <psmith@gnu.org>
4167 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4168 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4169 * make.h: Define these macros.
4171 * Version 3.79.1 released.
4173 * configure.in: Add a new option, --disable-nsec-timestamps, to
4174 avoid using sub-second timestamps on systems that support it. It
4175 can lead to problems, e.g. if your makefile relies on "cp -p".
4176 * README.template: Document the issue with "cp -p".
4178 * config.guess, config.sub: Updated.
