549 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
550 targets. Enter into doc/ to produce the targets.
551 (all-am): $(INFO_DEPS) replaced by info.
553 2009-09-26 Paul Smith <psmith@gnu.org>
555 * read.c (record_files): Use free_ns() to free struct nameseq.
558 * rule.c (freerule): Use free_dep_chain().
560 * read.c (record_files): Free FILENAMES chain for implicit rules.
561 (eval): Static pattern targets go into the string cache.
563 * function.c (string_glob): Free NAME in the nameseq chain.
565 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
567 * implicit.c (pattern_search): Terminate early if we haven't
568 found any rules to try (performance improvement).
570 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
572 * implicit.c (pattern_search): Merge three parallel arrays,
573 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
574 of struct TRYRULE. In the old version the latter two arrays
575 had insufficient length.
577 2009-09-24 Paul Smith <psmith@gnu.org>
579 * implicit.c (pattern_search): Add back support for order-only
580 prerequisites for secondary expansion implicit rules, that were
581 accidentally dropped. If we find a "|", enable order-only mode
582 and set IGNORE_MTIME on all deps that are seen afterward.
583 (pattern_search): Fix memory leaks: for intermediate files where
584 we've already set the file variable and pattern variable sets, be
585 sure to either save or free them as appropriate.
587 2009-09-23 Paul Smith <psmith@gnu.org>
589 Rework the way secondary expansion is stored, for efficiency.
590 This changes secondary expansion so that ONLY WHEN we know we have
591 a possibility of needing secondary expansion, do we defer the
592 secondary expansion. This means more parsing the deps but we use
593 a lot less memory (due to the strcache). Also, this fixes
596 * read.c (eval): Don't parse the dep string here anymore.
597 (record_files): Take the dep argument as an unparsed string. If
598 secondary expansion is enabled AND the prereq string has a '$' in
599 it, then set NEED_2ND_EXPANSION and keep the entire string.
600 Otherwise, parse the dep string here to construct the dep list
601 with the names in the strcache.
603 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
604 duplicate the name string (others are in the strcache).
606 * implicit.c: Remove struct idep and free_idep_chain(): unused.
607 (struct patdeps): New structure to store prereq information.
608 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
609 which prerequisites need expansion, and expand only those.
611 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
612 and enter_prereqs(). split_prereqs() takes a fully-expanded string
613 and splits it into a DEP list, handling order-only prereqs.
614 (enter_prereqs): This function enters a list of DEPs into the file
615 database. If there's a stem defined, expand any pattern chars.
616 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
617 set. Use the above functions.
618 (snap_deps): Only perform second expansion on prereqs that need it,
619 as defined by the NEED_2ND_EXPANSION flag.
620 (print_prereqs): New function to print the prereqs
621 (print_file): Call print_prereqs() rather than print inline.
623 * hash.h (STRING_COMPARE): Take advantage of strcache() by
625 (STRING_N_COMPARE): Ditto.
626 (ISTRING_COMPARE): Ditto.
628 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
629 (parse_file_seq): Return void*
630 * read.c (parse_file_seq): Return void*.
631 (eval): Invoke macroized version of parse_file_seq()
632 * default.c (set_default_suffixes): Ditto.
633 * file.c (split_prereqs): Ditto.
634 * function.c (string_glob): Ditto.
635 * main.c (main): Ditto.
636 * rule.c (install_pattern_rule): Ditto.
638 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
640 2009-09-16 Paul Smith <psmith@gnu.org>
642 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
644 * dep.h: Create alloc_dep() / free_dep() macros.
646 * implicit.c (pattern_search): Take advantage of the new
647 parse_file_seq() to add the directory prefix to each prereq.
649 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
650 all. Avoid reversing chains. Support adding prefixes.
651 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
652 cached/non-cached results.
653 (eval): Remove multi_glob() & invoke new parse_file_seq().
654 * rule.c (install_pattern_rule): Ditto.
655 * main.c (main): Ditto.
656 * implicit.c (pattern_search): Ditto.
657 * function.c (string_glob): Ditto.
658 * file.c (parse_prereqs): Ditto.
659 * default.c (set_default_suffixes): Ditto.
661 * variable.c (parse_variable_definition): Don't run off the end of
662 the string if it ends in whitespace (found with valgrind).
664 * commands.c (set_file_variables): Keep space for all targets in
665 $? if -B is given (found with valgrind).
667 2009-09-15 Paul Smith <psmith@gnu.org>
669 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
670 (xcalloc): Add new function.
671 * make.h: New declarations.
673 * ar.c (ar_glob_match): New calling method for concat().
674 * main.c (main): Ditto.
675 (decode_env_switches): Ditto.
676 * read.c (eval_makefile): Ditto.
677 (tilde_expand): Ditto.
678 (parse_file_seq): Ditto.
679 * variable.c (target_environment): Ditto.
680 (sync_Path_environment): Ditto.
682 * ar.c (ar_glob_match): Use xcalloc().
683 * dir.c (file_impossible): Ditto.
684 * file.c (enter_file): Ditto.
685 * job.c (new_job): Ditto.
686 * read.c (parse_file_seq): Ditto.
687 * vmsfunctions.c (opendir): Ditto.
689 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
691 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
692 inside the loop that looks up environment for PATH.
694 2009-08-31 Eli Zaretskii <eliz@gnu.org>
696 * function.c (windows32_openpipe): Update envp after calling
697 sync_Path_environment.
699 2009-08-02 Paul Smith <psmith@gnu.org>
701 * remake.c (notice_finished_file): Ensure file->cmds is not null
702 before looping through them. Fixes Savannah bug #21824.
704 * doc/make.texi (Wildcard Examples): Clarify when objects is
705 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
706 (Include): Clarify the behavior of -include.
707 Fixes Savannah bug #18963.
709 2009-08-01 Paul Smith <psmith@gnu.org>
711 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
712 etc. come on the command line. Fixes Savannah bug #27093.
714 * expand.c (expand_argument): If the argument is large enough use
715 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
717 * variable.c (do_variable_definition): Avoid using alloca() to
718 hold values, which can be large. Fixes Savannah bug #23960.
720 * job.c (new_job): Use memmove() instead of strcpy() since both
721 pointers are in the same memory block. Fixes Savannah bug #27148.
722 Patch by Petr Machata.
724 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 * job.c (construct_command_argv_internal): Add "ulimit" and
727 "unset" to the sh_cmds for Unixy shells.
729 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
731 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
732 that set make_cv_sys_gnu_glob, so they are also correctly set
733 when the cache has been populated before.
735 2009-07-04 Eli Zaretskii <eliz@gnu.org>
737 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
738 exist, as realpath(3) does where it's supported.
740 2006-07-04 Eli Zaretskii <eliz@gnu.org>
742 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
743 (abspath): Support systems that define HAVE_DOS_PATHS (have
744 drive letters in their file names). Use IS_PATHSEP instead of a
745 literal '/' comparison. Fixes Savannah bug #26886.
747 2009-06-14 Paul Smith <psmith@gnu.org>
749 * remake.c (update_file_1): Remember the original file we marked
750 as updating, so we can clear that flag again. If we find a target
751 via vpath, FILE might change.
752 (check_dep): Ditto. Fixes Savannah bug #13529.
753 Patch by Reid Madsen <reid.madsen@tek.com>.
755 2009-06-13 Paul Smith <psmith@gnu.org>
757 * doc/make.texi (MAKEFILES Variable): Be explicit that files
758 included by MAKEFILES cannot give default goals.
759 * read.c (eval): If set_default is not set, pass the no-default-goal
760 value when we read included makefiles. Fixes Savannah bug #13401.
762 * ar.c (ar_name): Ensure that targets with empty parens aren't
763 considered archive member references: archive members must have a
764 non-empty "member" string. Fixes Savannah bug #18435.
766 * function.c (string_glob): Rely on multi_glob() to determine
767 whether files exist or not. Remove call to file_exists_p() which
768 is not always correct. Fixes Savannah bug #21231.
769 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
770 then only files that really exist will be returned.
771 * dep.h: Add new argument to multi_glob().
772 * rule.c (install_pattern_rule): Ditto.
773 * read.c (eval): Ditto.
774 * main.c (main): Ditto.
775 * implicit.c (pattern_search): Ditto.
776 * file.c (parse_prereqs): Ditto.
777 * default.c (set_default_suffixes): Ditto.
779 2009-06-09 Paul Smith <psmith@gnu.org>
781 * commands.c (set_file_variables): If always_make_flag is set,
782 always add the prereq to $?. Fixes Savannah bug #17825.
784 * remake.c (update_file_1): When rebuilding deps of FILE, also try
785 to rebuild the deps of all the also_make targets for that file.
786 Fixes Savannah bug #19108.
788 * implicit.c (pattern_search): Undo test for is_target, added by
789 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
790 Rule Search Algorithm". Fixes Savannah bug #17752.
792 * main.c (clean_jobserver): Clear the jobserver_fds options and
793 set job_slots to the default when we clean up.
794 (define_makeflags): Return the new MAKEFLAGS value.
795 (main): Reset MAKEFLAGS in the environment when we re-exec.
796 Fixes Savannah bug #18124.
798 2009-06-08 Paul Smith <psmith@gnu.org>
800 * read.c (eval): Collapse continuations post-semicolon on target-
801 specific variables. Fixes Savannah bug #17521.
803 2009-06-07 Paul Smith <psmith@gnu.org>
805 * job.c (reap_children): For older systems without waitpid() (are
806 there any of these left?) run wait(2) inside EINTRLOOP to handle
807 EINTR errors. Fixes Savannah bug #16401.
809 * (various): Debug message cleanup. Fixes Savannah bug #16469.
811 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
813 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
814 not the end, to catch second expansion $(eval ...) defining new
815 target/prereq relationships during snap_deps.
816 Fixes Savannah bug #24622.
818 * read.c (record_files): The second-expansion "f->updating" hack
819 was not completely correct: if assumed that the target with
820 commands always had prerequisites; if one didn't then the ordering
821 was messed up. Fixed for now to use f->updating to decide whether
822 to preserve the last element in the deps list... but this whole
823 area of constructing and reversing the deps list is too confusing
824 and needs to be reworked. Fixes Savannah bug #21198.
826 2009-06-06 Paul Smith <psmith@gnu.org>
828 * hash.c (hash_insert): Remove useless test for NULL.
829 Fixes Savannah bug #21823.
831 * make.h: Move SET_STACK_SIZE determination to make.h.
832 * main.c (main): New global variable, STACK_LIMIT, holds the
833 original stack limit when make was started.
834 * job.c (start_job_command): Reset the stack limit, if we changed it.
835 Fixes Savannah bug #22010.
837 * remake.c (check_dep): Only set the target's state to not-started
838 if it's not already running. Found this while testing -j10 builds
839 of glibc: various targets were being rebuilt multiple times.
840 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
843 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
844 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
847 2009-06-04 Paul Smith <psmith@gnu.org>
849 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
851 * maintMakefile: Modify access of config and gnulib Savannah
852 modules to use GIT instead of CVS.
854 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
855 Fixes Savannah bug #24655.
857 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
858 this can happen during some invocations of $(eval ...) for example.
859 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
861 2009-06-02 Paul Smith <psmith@gnu.org>
863 * configure.in: Check for fileno()
864 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
865 for the makefile file so invocations of $(shell ...) don't inherit it.
866 Fixes Savannah bug #24277.
868 2009-06-01 Paul Smith <psmith@gnu.org>
870 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
871 expansion was handled incorrectly. Rework the default goal
872 handling to save the variable only. Remove default_goal_file and
874 * read.c (eval): Check default_goal_var, not default_goal_name.
875 * read.c (record_target_var): Don't check default_goal_file here.
877 2009-05-31 Paul Smith <psmith@gnu.org>
879 * main.c (main): Expand the .DEFAULT_GOAL variable before using
880 it, and if the multi_glob() returns nothing (say it expanded to
881 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
883 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
884 $(and ..) to the reference. Fixes Savannah bug #25694.
886 * make.1: Be clear that some recipes will be executed even with -n.
887 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
889 * doc/make.texi (Override Directive): Make more clear how
890 overrides and appends interact.
891 Elucidates part of Savannah bug #26207.
893 * read.c (record_target_var): Don't reset the origin on
894 target-specific variables; try_variable_definition() will handle
895 this correctly. Fixes Savannah bug #26207.
897 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
898 Fixes Savannah bug #25712.
900 * implicit.c (pattern_search): Keep a pointer to the beginning of
901 the filename and save that instead of the constructed pointer.
902 Fixes Savannah bug #26593.
903 Patch by Mark Seaborn <mrs@mythic-beasts.com>
905 2009-05-30 Paul Smith <psmith@gnu.org>
907 * doc/make.texi (Multi-Line): Add a description of the new abilities
908 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
909 "command sequence" vs. "recipe" syntax.
910 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
911 after a define, to create variables with those flavors.
913 2009-05-25 Paul Smith <psmith@gnu.org>
915 Reworked the parser for variable assignments to allow multiple
916 modifiers, and in any order. Also allows variable and
917 prerequisites to be modifier names ('export', 'private', etc.)
919 * NEWS: Add notes about user-visible changes.
921 * read.c (struct vmodifiers): Remember what modifiers were seen.
922 (parse_var_assignment): New function to parse variable assignments.
923 (eval): Call the new function. Handle variable assignments earlier.
925 * variable.c (parse_variable_definition): Only parse; don't create var.
926 (assign_variable_definition): Call parse, then create the var.
928 2009-05-24 Paul Smith <psmith@gnu.org>
930 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
931 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
933 2009-03-14 Eli Zaretskii <eliz@gnu.org>
935 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
936 Fixes Savannah bug #25412.
938 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
939 prototype for xmalloc.
940 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
941 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
942 Loop over an array of extensions, instead of duplicating the same
943 code inline. Use SearchPath followed by CreateFile, instead of
944 the obsolete OpenFile. Fixes Savannah bug #17277.
945 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
946 to `find_file'. Fixes Savannah bug #25662.
948 2009-03-07 Eli Zaretskii <eliz@gnu.org>
950 * function.c (func_shell): Don't close pipedes[1] if it is -1.
951 Fixes Savannah bug #20495.
953 2009-02-28 Ralf Wildenhues <address@hidden>
955 * doc/make.texi (Instead of Execution): Document interaction of
956 -t with phony targets.
958 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
960 Introduce a new keyword "private" which applies to target-specific
961 variables and prevents their values from being inherited.
963 * variable.h (struct variable): Add private_var flag to each variable.
964 Add a flag to specify which list entry switches to the parent target.
965 * variable.c (define_variable_in_set): Initialize private_var flag.

984 2008-09-30 Eli Zaretskii <eliz@gnu.org>
986 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
989 * w32/subproc/build.bat (GCCBuild): Likewise.
991 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
993 * job.c (construct_command_argv_internal): Avoid extra backslash
994 in batch-mode Unixy shells. Under DB_JOBS, display the contents
997 2008-05-31 Eli Zaretskii <eliz@gnu.org>
999 * README.W32.template: Remove obsolete text about non-support for
1000 -jN without Unixy shell. Remove obsolete text about not supplying
1001 Visual Studio project files (we do supply them). Modify text to
1002 prefer GCC builds to MSC builds.
1004 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1006 * doc/make.texi (Empty Targets): Fix typo.

1021 `value' field is NULL.
1023 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1025 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1027 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1028 (TEXINFOS): Value changed to `doc/make.texi'.
1029 (.SUFFIXES): Use .texi instead of .texinfo.
1030 (make.info, make.dvi): Depend on doc/make.texi.
1031 (.texi.info): New target, instead of ".texinfo.info". Change -I
1032 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1033 (.texi): New target, instead of ".texinfo". Change -I switch to
1034 $(MAKEINFO) to look in doc/. Use --no-split.
1035 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1036 switch to $(MAKEINFO) to look in doc/.
1037 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1038 "*.i[0-9][0-9]" (due to --no-split above).
1039 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1040 (html, make_1.html): New targets.
1041 (.PHONY): Add "html".
1042 (.SUFFIXES): Add .html.
1044 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1046 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1047 HAVE_DECL_SYS_SIGLIST.
1049 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1050 build does not use child_execute_job.
1052 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1053 export the SHELL environment variable to the child.
1055 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1057 * config.h.W32: Include sys/types.h.

1077 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1079 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1080 a more complex value than a simple shell: if it's not a default
1081 shell now then expand it and see if is a default shell then.
1083 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1085 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1086 pathnames, with const strings.

1090 2007-10-10 Paul Smith <psmith@gnu.org>
1092 * make.h: Add a prototype for w32_kill() (change suggested by

1107 2007-09-11 Paul Smith <psmith@gnu.org>
1109 * doc/make.texi (Special Variables): Moved this into the "How to
1110 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1114 (Simple Makefile): Ditto.
1115 (Rule Syntax): Ditto.
1116 (Command Syntax): Ditto.
1117 (Error Messages): Ditto.
1119 2007-09-10 Paul Smith <psmith@gnu.org>
1121 * commands.c (print_commands): Don't print an extra line in the
1122 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1124 * read.c (construct_include_path): Add the full string to the cache; we
1125 were chopping the last char.
1127 * NEWS: Announce the .RECIPEPREFIX special variable.
1128 * variable.c (lookup_special_var): Rename from handle_special_var().
1129 (lookup_variable): Call the new name.
1130 (set_special_var): New function: handle setting of special variables.
1131 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1134 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1135 * main.c (main): Create the .RECIPEPREFIX special variable.
1136 * read.c (eval): Remove the cmd_prefix characters from the command
1137 scripts here, so they're not stored in the commands array at all,
1138 rather than waiting and stripping them out during command construction.
1139 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1141 2007-08-15 Paul Smith <psmith@gnu.org>
1143 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1144 file has had the section info removed, so add some to make.texi
1145 before we include it.
1147 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1149 * remake.c (check_dep): Reset the target state for intermediate
1150 files. They might have been considered before but not updated

1165 2007-07-13 Paul Smith <psmith@gnu.org>
1167 * file.c (expand_deps): Use variable_buffer as the start of the
1168 buffer, not the original pointer (in case it was reallocated).
1169 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1170 Fixes Savannah bug #20452.

1207 Dave Korn <dave.korn@artimi.com>
1209 2007-05-08 Paul Smith <psmith@gnu.org>
1211 Fix Savannah bug #19656:
1213 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1215 * make.h: Change all case-insensitive string compares to use
1216 strcasecmp() (from POSIX). If we don't have that but do have one
1217 of the others, define strcasecmp to be one of those instead. If
1218 we don't have any, declare a prototype for our own version.
1220 * misc.c (strcasecmp): Use this if we can't find any native
1221 case-insensitive string comparison function.
1222 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1223 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1225 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1226 strcasecmp() instead of stricmp().
1227 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1228 instead of strcmpi().
1229 * acinclude.m4: Remove the strcasecmp() check from here.
1231 2007-03-21 Paul Smith <psmith@gnu.org>
1233 * configure.in: Don't turn on case-insensitive file system support
1234 if --disable-... is given. Fixes Savannah bug #19348.
1236 2007-03-19 Paul Smith <psmith@gnu.org>
1238 * ALL: Use the strcache for all file name strings, or other
1239 strings which we will never free. The goal is to save memory by
1240 avoiding duplicate copies of strings. However, at the moment this
1241 doesn't save much memory in most situations: due to secondary
1242 expansion we actually save prerequisite lists twice (once before
1243 the secondary expansion, and then again after it's been parsed
1244 into individual file names in the dep list). We will resolve this
1245 in a future change, by doing the parsing up-front for targets
1246 where secondary expansion is not set.
1248 Moving things into the strcache also allows us to use const
1249 pointers in many more places.
1251 2007-01-03 Paul Smith <psmith@gnu.org>
1253 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1254 the function, not just the first. Fixes Savannah bug #18680.
1256 2006-11-18 Paul Smith <psmith@gnu.org>
1258 * strcache.c (strcache_add_len): Don't allocate a new buffer
1259 unless the string is not already nil-terminated. Technically this
1260 is a violation of the standard, since we may be passed an array
1261 that is not long enough to test one past. However, in make this
1262 is never true since we only use nil-terminated strings or
1263 sub-strings thereof.
1265 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1267 * main.c: New global cmd_prefix, defaults to '\t'.
1268 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1271 * dir.c: Constified.
1272 (dir_contents_file_exists_p): Check for an error return from
1273 readdir(), just in case.
1275 * commands.c: Constified.
1276 * default.c: Constified.
1277 * expand.c: Constified.
1278 * function.c: Partial constification.

1283 * w32/pathstuff.c: Partial constification.
1285 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1287 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1288 backslashes and drive letters as absolute.
1290 2006-10-22 Paul Smith <psmith@gnu.org>

1294 2006-10-21 Paul Smith <psmith@gnu.org>
1297 * arscan.c: Constified.
1299 2006-09-30 Paul Smith <psmith@gnu.org>
1301 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1302 point to lastword since the example was updated.
1303 Fixes Savannah bug #16304.
1304 (Secondary Expansion): Correct example description.
1305 Fixes Savannah bug #16468.
1306 (Makefile Contents): Clarify that comments cannot appear within
1307 variable references or function calls.
1308 Fixes Savannah bug #16577.
1309 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1310 Fixes Savannah bug #17701.
1311 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1313 prerequisites. Fixes Savannah bug #17880.
1314 (Rule Syntax): "lise" -> "list"
1315 (Multiple Rules): ... -> @dots{}
1316 (Splitting Lines): ditto.
1318 * remake.c (update_file_1): Prereqs that don't exist should be
1319 considered changed, for the purposes of $?.
1320 Fixes Savannah bug #16051.
1322 * make.1: Remove extraneous "+".
1323 Fixes Savannah bug #16652.

1359 2006-04-20 Paul D. Smith <psmith@gnu.org>
1361 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1362 that don't have extended grep.
1363 (cvsclean): Use $(PERL) instead of perl.
1365 2006-04-09 Paul D. Smith <psmith@gnu.org>
1367 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1369 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1370 inner-scope variables don't mask outer-scope variables.
1372 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1373 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:

1375 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1376 values from memory allocation functions: they return void* and so
1377 don't need to be cast. Also remove (char *) casts of arguments to

1431 Declare and define sh_chars_sh[].
1433 2006-03-23 Paul D. Smith <psmith@gnu.org>
1435 * configure.in: Look for build.sh.in in $srcdir so it will be
1436 built for remote configurations as well.
1438 * Makefile.am: Make sure to clean up build.sh during distclean.
1439 Fixes Savannah bug #16166.
1441 * misc.c (log_access): Takes a const char *.

1453 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1454 memory on hosts that don't support it directly.
1456 * README.cvs: Add information on steps for making a release (to
1457 make sure I don't forget any).
1459 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1461 (die): Cleanup code was removed from here; call the new function.
1462 (main): If we are re-execing, clean up the jobserver first so we
1463 don't leak file descriptors.

1477 (free_dep_chain): Use free_dep.
1478 * read.c (record_files): Store stem in the dependency line.

1493 Fixes Savannah bug #15913.
1495 2006-03-09 Paul Smith <psmith@gnu.org>
1497 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1498 listed non-existent files as changed. Turns out there's a bug in
1499 the Linux kernel builds which means that this change causes
1500 everything to rebuild every time. We will re-introduce this fix
1501 in the next release, to give them time to fix their build system.
1502 Fixes Savannah bug #16002.
1503 Introduces Savannah bug #16051.

1520 2006-02-19 Paul D. Smith <psmith@gnu.org>
1522 * commands.c (set_file_variables): Realloc, not malloc, the static
1523 string values to avoid memory leaks.
1525 * expand.c (recursively_expand_for_file): Only set reading_file to
1526 an initialized value.
1528 * implicit.c (pattern_search): We need to make a copy of the stem
1529 if we get it from an intermediate dep, since those get freed.
1531 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1533 (enter_file) [VMS]: Ditto.

1538 * job.c (construct_command_argv_internal): Fix last change.
1540 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1541 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1542 the calls to _beginthreadex.
1544 * expand.c (recursively_expand_for_file): Initialize `save' to
1545 prevent compiler warnings.
1547 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1549 * job.c (construct_command_argv_internal): Don't create a temporary
1550 script/batch file if we are under -n. Call _setmode to switch the
1551 script file stream to text mode.

1555 * variable.c (merge_variable_set_lists): Don't try to merge the
1556 global_setlist. Not only is this useless, but it can lead to
1557 circularities in the linked list, if global_setlist->next in one
1558 list gets set to point to another list which also ends in
1560 Fixes Savannah bug #15757.
1562 2006-02-15 Paul D. Smith <psmith@gnu.org>
1564 Fix for Savannah bug #106.
1566 * expand.c (expanding_var): Keep track of which variable we're
1567 expanding. If no variable is being expanded, it's the same as
1569 * make.h (expanding_var): Declare it.
1570 * expand.c (recursively_expand_for_file): Set expanding_var to the
1571 current variable we're expanding, unless there's no file info in
1572 it (could happen if it comes from the command line or a default
1573 variable). Restore it before we exit.

1586 empty string we still need to free the allocated buffer.
1588 * implicit.c (pattern_search): If we allocated a variable set for
1589 an impossible file, free it.
1590 * variable.c (free_variable_set): New function.
1591 * variable.h: Declare it.
1593 * read.c (read_all_makefiles): Makefile names are kept in the
1594 strcache, so there's never any need to alloc/free them.
1597 * main.c (main): Add "archives" to the .FEATURES variable if
1598 archive support is enabled.
1599 * doc/make.texi (Special Variables): Document it.
1601 2006-02-13 Paul D. Smith <psmith@gnu.org>
1603 * implicit.c (pattern_search): Add checking for DOS pathnames to
1604 the pattern rule target LASTSLASH manipulation.

1609 * (ALL FILES): Updated copyright and license notices.
1611 2006-02-10 Paul D. Smith <psmith@gnu.org>
1613 A new internal capability: the string cache is a read-only cache
1614 of strings, with a hash table interface for fast lookup. Nothing
1615 in the cache will ever be freed, so there's no need for reference
1616 counting, etc. This is the beginning of a full solution for
1617 Savannah bug #15182, but for now we only store makefile names here.
1619 * strcache.c: New file. Implement a read-only string cache.
1620 * make.h: Add prototypes for new functions.
1621 * main.c (initialize_global_hash_tables): Initialize the string cache.
1622 (print_data_base): Print string cache stats.
1623 * read.c (eval_makefile): Use the string cache to store makefile
1624 names. Rewrite the string allocation to be sure we free everything.
1626 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1628 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1629 directory time stamp didn't change, except on FAT filesystems.
1630 Suggested by J. David Bryan <jdbryan@acm.org>.
1632 2006-02-09 Paul D. Smith <psmith@gnu.org>
1634 * function.c (func_or): Implement a short-circuiting OR function.
1635 (func_and): Implement a short-circuiting AND function.
1636 (function_table_init): Update the table with the new functions.
1637 * doc/make.texi (Conditional Functions): Changed the "if" section
1638 to one on general conditional functions. Added documentation for
1639 $(and ...) and $(or ...) functions.
1640 * NEWS: Note new $(and ...) and $(or ...) functions.
1642 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1644 * job.h (struct child): Add the dontcare bitfield.
1645 * job.c (new_job): Cache dontcare flag.
1646 * job.c (reap_children): Use cached dontcare flag instead of the
1647 one in struct file. Fixes Savannah bug #15641.
1649 2006-02-06 Paul D. Smith <psmith@gnu.org>
1651 * vpath.c (selective_vpath_search): If the file we find has a
1652 timestamp from -o or -W, use that instead of the real time.
1653 * remake.c (f_mtime): If the mtime is a special token from -o or
1654 -W, don't overwrite it with the real mtime.
1655 Fixes Savannah bug #15341.
1657 Updates from Markus Mauhart <qwe123@chello.at>:
1659 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1668 2006-02-05 Paul D. Smith <psmith@gnu.org>
1670 * file.c (enter_file): Keep track of the last double_colon entry,
1671 to avoid walking the list every time we want to add a new one.
1672 Fixes Savannah bug #15533.
1673 * filedef.h (struct file): Add a new LAST pointer.
1675 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1676 the comparison. For 64-bits systems the result of the subtraction
1677 might not fit into an int. Use comparison instead.
1678 Fixes Savannah bug #15534.
1680 * doc/make.texi: Update the chapter on writing commands to reflect
1681 the changes made in 3.81 for backslash/newline and SHELL handling.

1701 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1703 * remake.c (update_goal_chain): Set g->changed instead of
1704 incrementing it, as it is only 8-bit wide, and could overflow if
1705 many commands got started in update_file.
1707 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1709 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1710 MAXIMUM_WAIT_OBJECTS.
1711 (process_wait_for_any_private): Change dimension of handles[]
1712 array to MAXIMUM_WAIT_OBJECTS.
1713 (process_used_slots): New function.
1714 (process_register): Don't register more processes than the
1715 available number of slots.
1716 (process_easy): Don't start new processes if all slots are used up.
1718 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1719 are already more children than sub_proc.c can handle, behave as if
1720 the load were too high.
1721 (start_job_command): Fix a typo in error message when process_easy
1724 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1726 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1727 the shell is not sh.exe.
1729 * job.c (create_batch_file): Renamed from create_batch_filename;
1730 all callers changed. Don't close the temporary file; return its
1731 file descriptor instead. New arg FD allows to return the file
1733 (construct_command_argv_internal): Use _fdopen instead of fopen to
1734 open the batch file.
1736 2006-01-04 Paul D. Smith <psmith@gnu.org>
1738 * readme.vms: Updates for case-insensitive VMS file systems from
1739 Hartmut Becker <Hartmut.Becker@hp.com>.

1750 * remake.c (update_file_1): Mark a prerequisite changed if it
1753 * read.c (eval): Be sure to strip off trailing whitespace from the
1754 prerequisites list properly. Also, initialize all fields in
1755 struct dep when creating a new one.
1757 2005-12-28 Paul D. Smith <psmith@gnu.org>
1759 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1760 disable warnings for MSC.
1761 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1763 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1765 * doc/make.texi (Execution): Add a footnote about changes in
1766 handling of backslash-newline sequences. Mention the differences
1767 on MS-DOS and MS-Windows.
1769 * NEWS: More details about building the MinGW port and a pointer
1770 to README.W32. Fix the section name that describes the new
1771 backward-incompatible processing of backslash-newline sequences.
1772 The special processing of SHELL set to "cmd" is only relevant to
1773 MS-Windows, not MS-DOS.
1775 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1777 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1778 to DWORD, to avoid compiler warnings.
1779 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1780 use %ld in format, to avoid compiler warnings.
1782 * doc/make.texi (Special Targets): Fix a typo.
1783 (Appending): Fix cross-reference to Setting.
1784 (Special Variables, Secondary Expansion, File Name Functions)
1785 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1786 periods after a sentence.
1787 (Execution): Add @: after "e.g.".

1792 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1794 * read.c (record_target_var): Initialize variable's export field
1795 with v_default instead of leaving it "initialized" by whatever
1796 garbage happened to be on the heap.
1798 2005-12-12 Paul D. Smith <psmith@gnu.org>
1800 * make.1: Fix some display errors and document all existing options.
1801 Patch by Mike Frysinger <vapier@gentoo.org>.
1803 2005-12-11 Paul D. Smith <psmith@gnu.org>
1805 * implicit.c (pattern_search): If 2nd expansion is not set for
1806 this implicit rule, replace the pattern with the stem directly,
1807 and don't re-expand the variable list. Along with the other
1808 .SECONDEXPANSION changes below, fixes bug #13781.
1810 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1812 * implicit.c (pattern_search): Mark other files that this rule
1813 builds as targets so that they are not treated as intermediates
1814 by the pattern rule search algorithm. Fixes bug #13022.
1816 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1818 * remake.c (notice_finished_file): Propagate the change of
1819 modification time to all the double-colon entries only if
1820 it is the last one to be updated. Fixes bug #14334.
1822 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1824 * function.c (func_flavor): Implement the flavor function which
1825 returns the flavor of a variable.
1826 * doc/make.texi (Functions for Transforming Text): Document it.
1827 * NEWS: Add it to the list of new functions.

1838 * read.c (record_files): Don't set deps flags if there are no deps.
1839 * maintMakefile: We only need to build the templates when we are
1840 creating a distribution, so don't do it for "all".
1842 2005-10-24 Paul D. Smith <psmith@gnu.org>
1844 Make secondary expansion optional: its enabled by declaring the
1845 special target .SECONDEXPANSION.
1847 * NEWS: Update information on second expansion capabilities.
1848 * doc/make.texi (Secondary Expansion): Document the
1849 .SECONDEXPANSION special target and its behavior.
1850 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1851 prerequisite list was found in a static pattern rule.
1852 (free_dep_chain): Declare a prototype.
1853 * file.c (parse_prereqs): New function: break out some complexity
1855 (expand_deps): If we aren't doing second expansion, replace % with
1856 the stem for static pattern rules. Call the new function.
1857 * filedef.h (parse_prereqs): Declare a prototype.
1858 * implicit.c (pattern_search): Initialize the new staticpattern
1860 * main.c (second_expansion): Declare a global variable to remember
1861 if the special target has been seen. Initialize the new
1862 staticpattern field for prerequisites.
1863 * make.h: Extern for second_expansion.
1864 * misc.c (free_dep_chain): New function: frees a struct dep list.
1865 * read.c (read_all_makefiles): Initialize the staticpattern field.
1866 (eval_makefile): Ditto.
1867 (record_files): Check for the .SECONDEXPANSION target and set
1868 second_expansion global if it's found.
1869 Use the new free_dep_chain() instead of doing it by hand.
1870 Set the staticpattern field for prereqs of static pattern targets.
1872 2005-10-16 Paul D. Smith <psmith@gnu.org>
1874 * main.c (main): Set CURDIR to be a file variable instead of a
1875 default, so that values of CURDIR inherited from the environment
1876 won't override the make value.
1878 2005-09-26 Paul D. Smith <psmith@gnu.org>
1880 * job.c (construct_command_argv_internal): If the line is empty
1881 remember to free the temporary argv strings.
1884 2005-09-16 Paul D. Smith <psmith@gnu.org>
1886 * job.c (start_job_command): The noerror flag is a boolean (single
1887 bit); set it appropriately.
1888 Reported by Mark Eichin <eichin@metacarta.com>
1890 2005-08-29 Paul D. Smith <psmith@gnu.org>
1892 * function.c (func_error): On Windows, output from $(info ...)
1893 seems to come in the wrong order. Try to force it with fflush().
1895 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1897 * read.c (record_files): Move code that sets stem for static
1898 pattern rules out of the if (!two_colon) condition so it is
1899 also executed for two-colon rules. Fixes Savannah bug #13881.
1901 2005-08-08 Paul D. Smith <psmith@gnu.org>
1903 * make.h: Don't test that __STDC__ is non-0. Some compilers
1904 (Windows for example) set it to 0 to denote "ISO C + extensions".
1907 2005-08-07 Paul D. Smith <psmith@gnu.org>
1909 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1910 conditional (slightly different version of a fix from Eli).
1912 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1913 If make is running in parallel without -k and two jobs die in a
1914 row, but not too close to each other, then make will quit without
1915 waiting for the rest of the jobs to die.
1917 * main.c (die): Don't reset err before calling reap_children() the
1918 second time: we still want it to be in the error condition.
1919 * job.c (reap_children): Use a static variable, rather than err,
1920 to control whether or not the error message should be printed.
1922 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1924 * w32/subproc/sub_proc.c: Include signal.h.
1925 (process_pipe_io, process_file_io): Pass a pointer to a local
1926 DWORD variable to GetExitCodeProcess. If the exit code is
1927 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1929 * job.c [WINDOWS32]: Include windows.h.
1930 (main_thread) [WINDOWS32]: New global variable.
1931 (reap_children) [WINDOWS32]: Get the handle for the main thread
1932 and store it in main_thread.
1934 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1935 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1936 doing anything else. When we are done, close the main thread
1937 handle and exit with status 130.
1939 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1941 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1944 * main.c (find_and_set_default_shell): If found a DOSish shell,
1945 set sh_found and the value of default_shell, and report the
1946 findings in debug mode.
1948 * job.c (construct_command_argv_internal): Check unixy_shell, not
1949 no_default_sh_exe, to decide whether to use Unixy or DOSish
1952 * README.W32: Update with info about the MinGW build.
1954 * build_w32.bat: Support MinGW.
1956 * w32/subproc/build.bat: Likewise.
1958 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1959 printing DWORD args.
1961 * function.c (windows32_openpipe): Fix format strings for printing
1964 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1966 (start_job_command): Fix format string for printing the result of
1968 (start_job_command) [WINDOWS32]: Do not define.
1969 (exec_command): Fix format string for printing HANDLE args.
1971 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1972 to avoid compiler warnings.
1973 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1974 (Note: some of these fixes were submitted independently by J. Grant)
1976 2005-07-30 J. Grant <jg@jguk.org>
1978 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1979 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1980 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1982 2005-07-15 Paul Smith <psmith@gnu.org>
1984 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1985 we don't have a POSIX shell, then revert to the old
1986 backslash-newline behavior (where they are stripped).
1989 2005-07-08 Paul D. Smith <psmith@gnu.org>
1991 * config.h.W32.template: Reorder to match the standard config.h,
1992 for easier comparisons.
1993 From J. Grant <jg@jguk.org>
1995 * maintMakefile: Remove .dep_segment before overwriting it, in
1996 case it's not writable or noclobber is set.
1997 * expand.c (variable_expand_string): Cast result of pointer
1998 arithmetic to avoid a warning.
1999 * main.c (switches): Add full-fledged final initializer.
2001 2005-07-06 Paul D. Smith <psmith@gnu.org>
2003 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2004 * signame.c (strsignal): If we found _sys_siglist[] or
2005 __sys_siglist[] use those instead of sys_siglist[].
2006 From Albert Chin <china@thewrittenword.com>
2008 2005-07-04 Paul D. Smith <psmith@gnu.org>
2010 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2011 globfree(); set up to use the GNU versions.
2012 From Martin Zinser <zinser@zinser.no-ip.info>
2014 2005-07-03 Paul D. Smith <psmith@gnu.org>
2016 From J. Grant <jg@jguk.org>:

2022 * w32/subproc/build.bat: Ditto.
2024 2005-06-28 Paul D. Smith <psmith@gnu.org>
2026 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2027 declaration was checked but not present.
2029 2005-06-27 Paul D. Smith <psmith@gnu.org>
2031 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2032 to unsigned long. Fixes Savannah bug #13550.
2034 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2035 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2036 Fixes Savannah bug #13551.
2038 2005-06-26 Paul D. Smith <psmith@gnu.org>
2040 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2041 it if ANSI_STRING is not set.
2043 2005-06-25 Paul D. Smith <psmith@gnu.org>
2045 * read.c (eval): If no filenames are passed to any of the
2046 "include" variants, don't print an error.
2047 * doc/make.texi (Include): Document this.
2048 Fixes Savannah bug #1761.
2050 * job.c (construct_command_argv_internal): Sanitize handling of
2051 backslash/newline pairs according to POSIX: that is, keep the
2052 backslash-newline in the command script, but remove a following
2053 TAB character, if present. In the fast path, make sure that the
2054 behavior matches what the shell would do both inside and outside
2055 of quotes. In the slow path, quote the backslash and put a
2056 literal newline in the string.
2057 Fixes Savannah bug #1332.
2058 * doc/make.texi (Execution): Document the new behavior and give
2060 * NEWS: Make a note of the new behavior.
2062 * make.h [WINDOWS32]: #include <direct.h>.
2063 Fixes Savannah bug #13478.
2065 * remake.c (name_mtime): If the stat() of a file fails and the -L
2066 option was given and the file is a symlink, take the best mtime of
2067 the symlink we can get as the mtime of the file and don't fail.
2068 Fixes Savannah bug #13280.
2070 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2071 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2072 inside a variable reference. Make this function static as it's
2074 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2075 parsing an unexpanded line looking for semicolons.
2076 Fixes Savannah bug #1454.
2077 * misc.c (remove_comments): Move this to read.c and make it static
2078 as it's only used there. Call find_char_unquote() with new arg.
2079 * make.h: Remove prototypes for find_char_unquote() and
2080 remove_comments() since they're static now.
2082 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2083 its export flag and obtain its value. When we need to re-exec,
2084 increment the value and add it into the environment.
2085 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2086 * NEWS: Mention MAKE_RESTARTS.
2087 * main.c (always_make_set): New variable. Change the -B option to
2088 set this one instead.
2089 (main): When checking makefiles, only set always_make_flag if
2090 always_make_set is set AND the restarts flag is 0. When building
2091 normal targets, set it IFF always_make_set is set.
2092 (main): Avoid infinite recursion with -W, too: only set what-if
2093 files to NEW before we check makefiles if we've never restarted
2094 before. If we have restarted, set what-if files to NEW _after_ we
2096 Fixes Savannah bug #7566:
2098 2005-06-17 Paul D. Smith <psmith@gnu.org>
2100 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2101 in the prerequisites list.
2103 2005-06-12 Paul D. Smith <psmith@gnu.org>
2105 Fix Savannah bug # 1328.
2107 * configure.in: Check for atexit().
2108 * misc.c (close_stdout): Test stdout to see if writes to it have
2109 failed. If so, be sure to exit with a non-0 error code. Based on
2110 code found in gnulib.
2111 * make.h: Prototype.
2112 * main.c (main): Install close_stdout() with atexit().
2114 2005-06-10 Paul D. Smith <psmith@gnu.org>
2116 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2118 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2119 headers; make vmsWaitForChildren() static; extern vmsify().
2120 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2121 Don't create child_execute_job() here (it's in vmsjobs.c).
2122 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2124 2005-06-09 Paul D. Smith <psmith@gnu.org>
2126 * variable.c (push_new_variable_scope): File variables point
2127 directly to the global_setlist variable. So, inserting a new
2128 scope in front of that has no effect on those variables: they
2129 don't go through current_variable_set_list. If we're pushing a
2130 scope and the current scope is global, push it "the other way" so
2131 that the new setlist is in the global_setlist variable, and
2132 next points to a new setlist with the global variable set.
2133 (pop_variable_scope): Properly undo a push with the new
2135 Fixes Savannah bug #11913.
2137 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2139 * job.c (reap_children): Don't die of the command failed but
2140 the dontcare flag is set. Fixes Savannah bug #13216.
2142 * implicit.c (pattern_search): When creating a target from
2143 an implicit rule match, lookup pattern target and set precious
2144 flag in a newly created target. Fixes Savannah bug #13218.
2146 2005-05-13 Paul D. Smith <psmith@gnu.org>
2148 Implement "if... else if... endif" syntax.
2150 * read.c (eval): Push all checks for conditional words ("ifeq",
2151 "else", etc.) down into the conditional_line() function.
2152 (conditional_line): Rework to allow "else if..." clause. New
2153 return value -2 for lines which are not conditionals. The
2154 ignoring flag can now also be 2, which means "already parsed a
2155 true branch". If that value is seen no other branch of this
2156 conditional can be considered true. In the else parsing if there
2157 is extra text after the else, invoke conditional_line()
2158 recursively to see if it's another conditional. If not, it's an
2159 error. If so, raise the conditional value to this level instead
2160 of creating a new conditional nesting level. Special check for
2161 "else" and "endif", which aren't allowed on the "else" line.
2162 * doc/make.texi (Conditional Syntax): Document the new syntax.
2164 2005-05-09 Paul D. Smith <psmith@gnu.org>
2166 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2167 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2168 recurses to the w32 directory, even on non-Windows systems. Use
2169 the method suggested in the automake manual.
2170 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2171 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2173 2005-05-07 Paul D. Smith <psmith@gnu.org>
2175 * main.c (die): If we're dying with a fatal error (not that a
2176 command has failed), write back any leftover tokens before we go.
2178 * job.c (set_child_handler_action_flags): If there are jobs
2179 waiting for the load to go down, set an alarm to go off in 1
2180 second. This allows us to wake up from a potentially long-lasting
2181 read() and start a new job if the load has gone down. Turn it off
2183 (job_noop): Dummy signal handler function.
2184 (new_job): Invoke it with the new semantics.
2186 * docs/make.texi: Document secondary expansion. Various cleanups
2189 2005-05-03 Paul D. Smith <psmith@gnu.org>
2191 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2192 the targets which are to ultimately be made are called "goals";
2193 see the GNU make manual. Also, MAKECMDGOALS, etc.
2195 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2196 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2197 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2199 2005-05-02 Paul D. Smith <psmith@gnu.org>
2201 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2202 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2203 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2204 functions to vmsjobs.c. #include it into jobs.c.
2206 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2207 jobserver tokens. I found that this happens when an exported
2208 recursive variable contains a $(shell ...) function reference: in
2209 this situation we could "forget" to write back a token.
2211 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2212 we have. It's not reliable to depend on the number of children in
2213 our linked list so keep a separate count.
2214 (new_job): Check jobserver_tokens rather than children &&
2215 waiting_jobs. Increment jobserver_tokens when we get one.
2216 (free_child): If jobserver_tokens is 0, internal error. If it's
2217 >1, write a token back to the jobserver pipe (we don't write a
2218 token for the "free" job). Decrement jobserver_tokens.
2220 * main.c: Add variable master_job_slots.
2221 (main): Set it to hold the number of jobs requested if we're the
2222 master process, when using the jobserver.
2223 (die): Sanity checks: first test jobserver_tokens to make sure
2224 this process isn't holding any tokens we didn't write back.
2225 Second, if master_job_slots is set count the tokens left in the
2226 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2228 2005-04-24 Paul D. Smith <psmith@gnu.org>
2230 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2231 with -l# can lose jobserver tokens, because waiting jobs are not
2232 consulted properly when checking for the "free" token.
2234 * job.c (free_child): Count waiting_jobs as having tokens.
2235 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2236 handle jobs waiting for the load to drop.
2238 2005-04-23 Paul D. Smith <psmith@gnu.org>
2240 * main.c (main): Be careful to not core if a variable setting in
2241 the environment doesn't contain an '='. This is illegal but can
2242 happen in broken setups.
2243 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2245 2005-04-12 Paul D. Smith <psmith@gnu.org>
2247 The second expansion feature causes significant slowdown. Timing
2248 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2249 read the makefile before the feature, to 11+s to do the same
2250 operations after the feature. Additionally, memory usage
2251 increased drastically. To fix this I added some intelligence that
2252 avoids the overhead of the second expansion unless it's required.
2254 * dep.h: Add a new boolean field, need_2nd_expansion.
2256 * read.c (eval): When creating the struct dep for the target,
2257 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2258 (record_files): If there's a "%" in a static pattern rule, it gets
2259 converted to "$*" so set need_2nd_expansion to 1.
2261 * file.c (expand_deps): Rework to be more efficient. Only perform
2262 initialize_file_variables(), set_file_variables(), and
2263 variable_expand_for_file() if the need_2nd_expansion is set.
2265 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2266 (pattern_search): Ditto.
2267 * main.c (handle_non_switch_argument): Ditto.
2269 * read.c (read_all_makefiles): Ditto.
2270 (eval_makefile): Ditto.
2272 2005-04-07 Paul D. Smith <psmith@gnu.org>
2274 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2275 * variable.c (sync_Path_environment): Ditto.
2276 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2278 * main.c (main): Define the .FEATURES variable.
2279 * NEWS: Announce .FEATURES.
2280 * doc/make.texi (Special Variables): Document .FEATURES.
2282 * remake.c (check_dep): If a file is .PHONY, update it even if
2283 it's marked intermediate. Fixes Savannah bug #12331.
2285 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2287 * file.c (expand_deps): Factor out the second expansion and
2288 prerequisite line parsing logic from snap_deps().
2290 * file.c (snap_deps): Use expand_deps(). Expand and parse
2291 prerequisites of the .SUFFIXES special target first. Fixes
2292 Savannah bug #12320.
2294 2005-03-13 Paul D. Smith <psmith@gnu.org>
2296 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2299 2005-03-11 Paul D. Smith <psmith@gnu.org>
2301 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2302 available, not undefined (from Earnie Boyd).
2304 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2306 * implicit.c (pattern_search): Mark an intermediate target as
2307 precious if it happened to be a prerequisite of some (other)
2308 target. Fixes Savannah bug #12267.
2310 2005-03-09 Paul D. Smith <psmith@gnu.org>
2312 * read.c (eval_makefile): Add alloca(0).
2313 (eval_buffer): Ditto.
2315 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2317 * main.c (main): Use o_file instead of o_default when defining
2318 the .DEFAULT_TARGET special variable.
2319 * read.c (eval): Use define_variable_global() instead of
2320 define_variable() when setting new value for the .DEFAULT_TARGET
2321 special variable. Fixes Savannah bug #12266.
2323 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2325 * imlicit.c (pattern_search): Mark files for which an implicit
2326 rule has been found as targets. Fixes Savannah bug #12202.
2328 2005-03-04 Paul D. Smith <psmith@gnu.org>
2331 * doc/make.texi (Automatic Variables): Document $|.
2333 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2335 * read.c (record_files): Instead of substituting % with
2336 actual stem value in dependency list replace it with $*.
2337 This fixes stem triple expansion bug.
2339 * implicit.c (pattern_search): Copy stem to a separate
2340 buffer and make it a properly terminated string. Assign
2341 this buffer instead of STEM (which is not terminated) to
2342 f->stem. Instead of substituting % with actual stem value
2343 in dependency list replace it with $*. This fixes stem
2344 triple expansion bug.
2346 2005-03-01 Paul D. Smith <psmith@gnu.org>
2348 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2349 on Windows, as it takes a handle not a pid. Just exit.
2350 Fix from patch #3679, provided by Alessandro Vesely.
2352 * configure.in: Update check for sys_siglist[] from autoconf manual.
2353 * signame.c (strsignal): Update to use the new autoconf macro.
2355 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2357 * read.c (record_files): Add a check for the list of prerequisites
2358 of a static pattern rule being empty. Fixes Savannah bug #12180.
2360 2005-02-28 Paul D. Smith <psmith@gnu.org>
2362 * doc/make.texi (Text Functions): Update docs to allow the end
2363 ordinal for $(wordlist ...) to be 0.
2364 * function.c (func_wordlist): Fail if the start ordinal for
2365 $(wordlist ...) is <1. Matches documentation.
2366 Resolves Savannah support request #103195.
2368 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2369 previously we were stopping when !-q, exactly the opposite. This
2370 has been wrong since version 1.34, in 1994!
2371 (update_file): If we got an error don't break out to run more
2372 double-colon rules: just return immediately.
2373 Fixes Savannah bug #7144.
2375 2005-02-27 Paul D. Smith <psmith@gnu.org>
2377 * misc.c (end_of_token): Make argument const.
2378 * make.h: Update prototype.
2380 * function.c (abspath, func_realpath, func_abspath): Use
2381 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2382 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2383 * read.c (record_files): Ditto.
2384 * variable.c (do_variable_definition): Ditto.
2386 * function.c (func_error): Create a new function $(info ...) that
2387 simply prints the message to stdout with no extras.
2388 (function_table_init): Add new function to the table.
2389 * NEWS: Add $(info ...) reference.
2390 * doc/make.texi (Make Control Functions): Document it.
2392 New feature: if the system supports symbolic links, and the user
2393 provides the -L/--check-symlink-time flag, then use the latest
2394 mtime between the symlink(s) and the target file.
2396 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2397 readlink(). If both are available, define MAKE_SYMLINKS.
2398 * main.c: New variable: check_symlink_flag.
2399 (usage): Add a line for -L/--check-symlink-times to the help string.
2400 (switches): Add -L/--check-symlink-times command line argument.
2401 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2402 print a warning and disable it again.
2403 * make.h: Declare check_symlink_flag.
2404 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2405 if the file is a symlink then check each link in the chain and
2406 choose the NEWEST mtime we find as the mtime for the file. The
2407 newest mtime might be the file itself!
2408 * NEWS: Add information about this new feature.
2409 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2411 Avoid core dumps described in Savannah bug # 12124:
2413 * file.c: New variable snapped_deps remember whether we've run
2415 (snap_deps): Set it.
2416 * filedef.h: Extern it.
2417 * read.c (record_files): Check snapped_deps; if it's set then
2418 we're trying to eval a new target/prerequisite relationship from
2419 within a command script, which we don't support. Fatal.
2421 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2423 Implementation of the .DEFAULT_TARGET special variable.
2425 * read.c (eval): If necessary, update default_target_name when
2427 * read.c (record_files): Update default_target_file if
2428 default_target_name has changed.
2429 * main.c (default_target_name): Define.
2430 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2431 default_target_name is set use default_target_file as a root
2433 * filedef.h (default_target_name): Declare.
2434 * dep.h (free_dep_chain):
2435 * misc.c (free_dep_chain): Change to operate on struct nameseq
2436 and change name to free_ns_chain.
2437 * file.c (snap_deps): Update to use free_ns_chain.
2439 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2441 Implementation of the second expansion in explicit rules,
2442 static pattern rules and implicit rules.
2444 * read.c (eval): Refrain from chopping up rule's dependencies.
2445 Store them in a struct dep as a single dependency line. Remove
2446 the code that implements SySV-style automatic variables.
2448 * read.c (record_files): Adjust the code that handles static
2449 pattern rules to expand all percents instead of only the first
2450 one. Reverse the order in which dependencies are stored so that
2451 when the second expansion reverses them again they appear in
2452 the makefile order (with some exceptions, see comments in
2453 the code). Remove the code that implements SySV-style automatic
2456 * file.c (snap_deps): Implement the second expansion and chopping
2457 of dependency lines for explicit rules.
2459 * implicit.c (struct idep): Define an auxiliary data type to hold
2460 implicit rule's dependencies after stem substitution and
2463 * implicit.c (free_idep_chain): Implement.
2465 * implicit.c (get_next_word): Implement helper function for
2466 parsing implicit rule's dependency lines into words taking
2467 into account variable expansion requests. Used in the stem
2470 * implicit.c (pattern_search): Implement the second expansion
2471 for implicit rules. Also fixes bug #12091.
2473 * commands.h (set_file_variables): Declare.
2474 * commands.c (set_file_variables): Remove static specifier.
2476 * dep.h (free_dep_chain): Declare.
2477 * misc.c (free_dep_chain): Implement.
2479 * variable.h (variable_expand_for_file): Declare.
2480 * expand.c (variable_expand_for_file): Remove static specifier.
2482 * make.h (strip_whitespace): Declare.
2483 * function.c (strip_whitespace): Remove static specifier.
2485 2005-02-26 Paul D. Smith <psmith@gnu.org>
2487 * main.c (main): Check for ferror() when reading makefiles from stdin.
2488 Apparently some shells in Windows don't close pipes properly and
2491 2005-02-24 Jonathan Grant <jg@jguk.org>
2493 * configure.in: Add MinGW configuration options, and extra w32 code
2495 * Makefile.am: Add MinGW configuration options, and extra w32 code
2497 * main.c: Determine correct program string (after last \ without .exe).
2498 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2500 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2501 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2502 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2503 environment support.
2505 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2507 * function.c (func_shell): When initializing error_prefix, check
2508 that reading file name is not null. This fixes long-standing
2509 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2511 2005-02-09 Paul D. Smith <psmith@gnu.org>
2513 * maintMakefile: Update the CVS download URL to simplify them.
2514 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2515 downloading the .texi files from Savannah now.
2517 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2519 * main.c (handle_non_switch_argument): Only add variables to
2520 command_variables if they're not already there: duplicate settings
2521 waste space and can be confusing to read.
2523 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2524 this header is never included by non-WINDOWS32 code, and it
2525 requires <config.h> to define which isn't always included first.
2527 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2528 testing MINGW32 versions.
2530 * main.c (log_working_directory): flush stdout to be sure the WD
2531 change is printed before any stderr messages show up.
2533 2005-02-01 Paul D. Smith <psmith@gnu.org>
2535 * maintMakefile (po_repo): Update the GNU translation site URL.
2537 2004-12-01 Paul D. Smith <psmith@gnu.org>
2539 * main.c (main): Change char* env_shell to struct variable shell_var.
2540 * variable.c (target_environment): Use new shell_var.
2542 2004-11-30 Paul D. Smith <psmith@gnu.org>
2544 * configure.in: The old way we avoided creating build.sh from
2545 build.sh.in before build.sh.in exists doesn't work anymore; we
2546 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2547 the help!). This also keeps automake from complaining.
2548 * Makefile.am (README): Add a dummy target so automake won't
2549 complain that this file doesn't exist when we checkout from CVS.
2550 * maintMakefile (.dep_segment): Rewrite this rule since newer
2551 versions of automake don't provide DEP_FILES.
2553 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2555 Implementation of `realpath' and `abspath' built-in functions.
2557 * configure.in: Check for realpath.
2558 * function.c (abspath): Return an absolute file name that does
2559 not contain any `.' or `..' components, nor repeated `/'.
2560 * function.c (func_abspath): For each name call abspath.
2561 * function.c (func_realpath): For each name call realpath
2562 from libc or delegate to abspath if realpath is not available.
2563 * doc/make.texi (Functions for File Names): Document new functions.
2564 * doc/make.texi (Quick Reference): Ditto.
2566 2004-11-28 Paul D. Smith <psmith@gnu.org>
2568 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2569 arguments. Fixes bug #10252.
2571 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2573 * main.c (main): Set SHELL to v_noexport by default. Remember the
2574 original environment setting of SHELL in the env_shell variable.
2575 * main.h: Export new env_shell variable.
2576 * variable.c (target_environment): If we find a v_noexport
2577 variable for SHELL, add a SHELL variable with the env_shell value.
2578 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2579 * doc/make.texi (Variables/Recursion): Ditto.
2581 2004-11-28 Paul D. Smith <psmith@gnu.org>
2583 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2584 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2585 Patch by Alessandro Vesely.
2587 2004-11-12 Paul D. Smith <psmith@gnu.org>
2589 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2590 the command line if it's inside a string.
2591 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2593 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2595 * function.c (func_lastword): New function: return last word
2596 from the list of words.
2597 * doc/make.texi: Document $(lastword ). Fix broken links in
2598 Quick Reference section.
2600 2004-10-06 Paul D. Smith <psmith@gnu.org>
2602 Apply patch from Alessandro Vesely, provided with bug # 9748.
2603 Fix use of tmpnam() to work with Borland C.
2605 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2606 construction of a temporary filename, and call new function
2607 create_batch_filename().
2608 (create_batch_filename) [WINDOWS32]: New function to create a
2611 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2613 * read.c (record_target_var): Expand simple pattern-specific
2615 * variable.c (initialize_file_variables): Do not expand simple
2616 pattern-specific variable.
2618 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2620 * remake.c (update_file_1): When rebuilding makefiles inherit
2621 dontcare flag from a target that triggered update.
2623 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2625 * variable.c (initialize_file_variables): Mark pattern-specific
2626 variable as a per-target and copy export status.
2628 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2630 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2632 * implicit.c (pattern_search): When considering an implicit rule's
2633 prerequisite check that it is actually a target rather then
2634 just an entry in the file hashtable.
2636 2004-09-21 Paul D. Smith <psmith@gnu.org>
2638 * read.c (readstring): Fix some logic errors in backslash handling.
2639 (eval): Remove some unnecessary processing in buffer handling.
2640 (record_target_var): Assert that parse_variable_definition() succeeded.
2641 Reported by: Markus Mauhart <qwe123@chello.at>.
2643 * misc.c: Removed the sindex() function. All instances of this
2644 function were trivially replaceable by the standard strstr()
2645 function, and that function will always have better (or certainly
2646 no worse) performance than the very simple-minded algorithm
2647 sindex() used. This can matter with complex makefiles.
2648 * make.h: Remove the prototype for sindex().
2649 * function.c (subst_expand): Convert sindex() call to strstr().
2650 This means we no longer need to track the TLEN value so remove that.
2651 (func_findstring): Convert sindex() to strstr().
2652 * commands.c (chop_commands): Convert sindex() calls to strstr().
2653 Suggested by: Markus Mauhart <qwe123@chello.at>.
2655 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2656 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2657 If SHELL is set to CMD.EXE then assume it's batch-mode and
2658 non-unixy. I wrote the code differently from the patch, though,
2659 to make it safer. This also resolves bug #9174.
2661 2004-09-20 Paul D. Smith <psmith@gnu.org>
2663 * expand.c (variable_expand_string): Modify to invoke
2664 patsubst_expand() instead of subst_expand(); the latter didn't
2665 handle suffix patterns correctly.
2666 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2667 was used only from variable_expand_string() and is no longer used
2669 (func_subst): Ditto, on call to subst_expand().
2670 (patsubst_expand): Require the percent pointers to point to the
2671 character after the %, not to the % itself.
2672 * read.c (record_files): New call criteria for patsubst_expand().
2673 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2674 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2676 2004-09-19 Paul D. Smith <psmith@gnu.org>
2678 * function.c (subst_expand): Fix a check in by_word: look for a
2679 previous blank if we're beyond the beginning of the string, not
2680 the beginning of the word.
2681 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2683 2004-05-16 Paul D. Smith <psmith@gnu.org>
2685 * remake.c (update_goal_chain): Change the argument specifying
2686 whether we're rebuilding makefiles to be a global variable,
2687 REBUILDING_MAKEFILES.
2688 (complain): Extract the code that complains about no rules to make
2689 a target into a separate function.
2690 (update_file_1): If we tried to rebuild a file during the makefile
2691 rebuild phase and it was dontcare, then no message was printed.
2692 If we then try to build the same file during the normal build,
2693 print a message this time.
2694 (remake_file): Don't complain about un-remake-able files when
2695 we're rebuilding makefiles.
2697 2004-05-11 Paul D. Smith <psmith@gnu.org>
2699 * job.c (construct_command_argv_internal): OS/2 patches from
2700 Andreas Buening <andreas.buening@nexgo.de>.
2702 2004-05-10 Paul D. Smith <psmith@gnu.org>
2704 * remake.c (update_file): Don't walk the double-colon chain unless
2705 this is a double-colon rule. Fix suggested by Boris Kolpackov
2706 <boris@kolpackov.net>.
2708 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2709 * readme.vms: New section describing OpenVMS support and issues.
2710 * default.c (default_variables): Add support for IA64.
2711 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2712 without some privilege aborts make with the error
2713 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2714 pressing Ctrl+Y and the input device is no terminal. The change
2715 catches this error and just continues.
2717 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2719 2004-04-25 Paul D. Smith <psmith@gnu.org>
2721 * commands.c (set_file_variables): Set $< properly in the face of
2722 order-only prerequisites.
2723 Patch from Boris Kolpackov <boris@kolpackov.net>
2725 2004-04-21 Bob Byrnes <byrnes@curl.com>
2727 * main.c (main): Notice failures to remake makefiles.
2729 2004-03-28 Paul D. Smith <psmith@gnu.org>
2731 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2733 * job.c: No default shell for RISC OS.
2734 (load_too_high): Hard-code the return to 1.
2735 (construct_command_argv_internal): No sh_chars or sh_cmds.
2736 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2738 2004-03-20 Paul D. Smith <psmith@gnu.org>
2740 * variable.c (do_variable_definition): Don't append from the
2741 global set if a previous non-appending target-specific variable
2742 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2745 * expand.c (reference_variable): Don't give up on variables with
2746 no value that have the target-specific append flag set: they might
2747 have a value after all. Reported by Oliver Schmidt
2748 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2749 <nikulin@dx1cmd.inp.nsk.su>.
2751 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2752 refer to absolute pathnames in directories that don't exist: some
2753 portion of the makefile could create those directories before we
2754 match the pattern. Fixes bugs #775 and #108.
2756 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2758 * main.c (main): Free makefile_mtimes if we have any.
2759 * README.W32.template: Update documentation for the current status
2760 of the MS-Windows port.
2761 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2762 environment variable is sometimes already defined which causes the
2764 * main.c (debug_signal_handler): Only define this function if
2765 SIGUSR1 is available.
2767 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2769 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2770 * README.OS2.template: Documentation updates.
2771 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2772 link line for safety.
2773 * maintMakefile (build.sh.in): Remove an extraneous ")".
2774 * job.c (child_execute_job): Close saved FDs.
2775 * job.c (exec_command) [OS/2]: exec_command(): If the command
2776 can't be exec'ed and if the shell is not Unix-sh, then try again
2777 with argv = { "cmd", "/c", ... }. Normally, this code is never
2778 reached for the cmd shell unless the command really doesn't exist.
2779 (construct_command_argv_internal) [OS/2]: The code for cmd
2780 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2781 The CMD builtin commands are case insensitive so use strcasecmp().
2783 2004-03-19 Paul D. Smith <psmith@gnu.org>
2785 * read.c (do_define): Re-order line counter increment so the count
2786 is accurate (we were losing one line per define). Reported by
2787 Dave Yost <Dave@Yost.com>.
2789 2004-03-06 Paul D. Smith <psmith@gnu.org>
2791 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2793 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2794 * misc.c (message,error,fatal): Ditto.
2795 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2796 * config.h.W32.template: Ditto.
2797 * config.h-vms.template: Ditto.
2798 * config.ami.template: Ditto.
2800 2004-03-04 Paul D. Smith <psmith@gnu.org>
2802 * README.template: Add a note about broken /bin/sh on SunOS
2803 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2805 * misc.c (message, error, fatal): Don't use "..." if we're using
2806 varargs. ansi2knr should handle this but it doesn't work: it
2807 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2808 done. On many systems (SunOS for example) va_dcl is a #define.
2809 So, force the use of the non-"..." version on pre-ANSI compilers.
2811 * maintMakefile (sign-dist): Create some rules to help automate
2812 the new GNU ftp upload method.
2814 2004-02-24 Paul D. Smith <psmith@gnu.org>
2816 * config.h.W32.template: Add HAVE_STDARG_H
2817 * config.h-vms.template: Ditto.
2818 * config.ami.template: Ditto.
2820 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2822 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2823 * build_w32.bat: Remove extra "+".
2825 2004-02-23 Paul D. Smith <psmith@gnu.org>
2827 * make.h: Create an UNUSED macro to mark unused parameters.
2828 * (many): Clean up warnings by applying UNUSED, fixing
2829 signed/unsigned incompatibilities, etc.
2831 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2833 * filedef.h: Name the command_state enumeration.
2834 * file.c (set_command_state): Use the enumeration in the function
2837 * configure.in: Explicitly set SET_MAKE to empty, to disable
2838 MAKE=make even when no make already exists. Fix bug #3823.
2840 2004-02-22 Paul D. Smith <psmith@gnu.org>
2842 * maintMakefile: Perl script to clean up all non-CVS files. Use
2843 it on all the subdirectories for the cvs-clean target.
2845 * main.c (decode_switches): Require non-empty strings for all our
2846 string command-line options. Fixes Debian bug # 164165.
2848 * configure.in: Check for stdarg.h and varargs.h.
2849 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2850 for printing messages.
2851 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2856 A number of patches for OS/2 support from Andreas Buening
2857 <andreas.buening@nexgo.de>:
2859 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2860 disable the SIGCHLD handler.
2861 (reap_children) [OS/2]: Remove special handling of job_rfd.
2862 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2863 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2864 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2865 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2866 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2869 2004-02-21 Paul D. Smith <psmith@gnu.org>
2871 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2872 <mail@kristov.de> reports that if process_begin() fails we don't
2873 handle the error condition correctly in all cases.
2874 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2875 to have a newline on the message.
2877 * job.c (construct_command_argv_internal): Add "test" to UNIX
2878 sh_cmds[]. Fixes Savannah bug # 7606.
2880 2004-02-04 Paul D. Smith <psmith@gnu.org>
2882 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2883 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2884 Hartmut Becker <Hartmut.Becker@hp.com>.
2886 2004-01-21 Paul D. Smith <psmith@gnu.org>
2888 * job.c (load_too_high): Implement an algorithm to control the
2889 "thundering herd" problem when using -l to control job creation
2890 via the load average. The system only recomputes the load once a
2891 second but we can start many jobs in a second. To solve this we
2892 keep track of the number of jobs started in the last second and
2893 apply a weight to try to guess what a correct load would be.
2894 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2895 Also fixes bug #4693.
2896 (reap_children): Decrease the job count for this second.
2897 (start_job_command): Increase the job count for this second.
2899 * read.c (conditional_line): Expand the text after ifn?def before
2900 checking to see if it's a single word. Fixes bug #7257.
2902 2004-01-09 Paul D. Smith <psmith@gnu.org>
2904 * file.c (print_file): Recurse to print all targets in
2905 double-colon rules. Fixes bug #4518, reported (with patch) by
2906 Andrew Chatham <chatham@google.com>.
2908 2004-01-07 Paul D. Smith <psmith@gnu.org>
2910 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2911 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2912 AC_FUNC_SETVBUF_REVERSED.
2914 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2915 (MAKE Variable): Fix Savannah bug #4898.
2917 * job.c (construct_command_argv_internal): Add "!" to the list of
2918 shell escape chars. POSIX sh allows it to appear before a
2919 command, to negate the exit code. Fixes bug #6404.
2921 * implicit.c (pattern_search): When matching an implicit rule,
2922 remember which dependencies have the ignore_mtime flag set.
2923 Original fix provided in Savannah patch #2349, by Benoit
2924 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2926 2003-11-22 Paul D. Smith <psmith@gnu.org>
2928 * README.W32.template (Outputs): Clarification on -j with
2929 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2932 2003-11-02 Paul D. Smith <psmith@gnu.org>
2934 * function.c (func_if): Strip all the trailing whitespace from the
2935 condition, then don't expand it. Fixed bug # 5798.
2937 * expand.c (recursively_expand_for_file): If we're expanding a
2938 variable with no file context, then use the variable's context.
2941 2003-10-21 Paul D. Smith <psmith@gnu.org>
2943 * main.c (log_working_directory): Add newlines to printf()s.
2945 * README.cvs: Add a note to ignore warnings during autoreconf.
2947 * maintMakefile (po_repo): Set a new URL for PO file updates.
2948 (get-config/config.guess get-config/config.sub): Get these files
2949 from the Savannah config project instead of ftp.gnu.org.
2951 2003-10-05 Paul Eggert <eggert@twinsun.com>
2953 * main.c (main): Avoid potential subscript error if environ has
2956 2003-08-22 Paul D. Smith <psmith@gnu.org>
2958 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2959 systems which don't yet implement the C89 standard :-/.
2961 2003-07-18 Paul D. Smith <psmith@gnu.org>
2963 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2964 [WINDOWS32]: Initialize hash.
2966 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2968 * dir.c (read_dirstream): Provide a workaround for broken versions of
2969 the MinGW dirent structure.
2971 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2973 * w32/include/dirent.h: Add __MINGW32__ filter.
2975 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2977 * make.h: Add global declaration of *make_host.
2978 * main.c (print_usage): Remove local declaration of *make_host.
2979 (print_version): Display "This program built for ..." after Copyright
2982 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2984 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2985 execution of "makeinfo --html make.texi".
2987 2003-04-30 Paul D. Smith <psmith@gnu.org>
2989 * build.template: Make some changes to maybe allow this script to
2990 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2992 * README.OS2.template: New file for OS/2 support. Original
2993 contributed by Andreas Buening.
2994 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2997 2003-04-19 Paul D. Smith <psmith@gnu.org>
2999 Fix bug #1405: allow a target to match multiple pattern-specific
3002 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3003 variable.c, where they've always belonged.
3004 * rule.h: Move the prototypes and struct pattern_var as well.
3005 * variable.c (initialize_file_variables): Invoke
3006 lookup_pattern_var() in a loop, until no more matches are found.
3007 If a match is found, create a new variable set for the target's
3008 pattern variables. Then merge the contents of each matching
3009 pattern variable set into the target's pattern variable set.
3010 (lookup_pattern_var): Change this function to be usable
3011 in a loop. It takes a starting position: if NULL, start at the
3012 beginning; if non-NULL, start with the pattern variable after that
3013 position, and return the next matching pattern.
3014 (create_pattern_var): Create a unique instance of
3015 pattern-specific variables for every definition in the makefile.
3016 Don't combine the same pattern together. This allows us to
3017 process the variable handling properly even when the same pattern
3018 is used multiple times.
3019 (parse_variable_definition): New function: break out the parsing
3020 of a variable definition line from try_variable_definition.
3021 (try_variable_definition): Call parse_variable_definition to
3023 (print_variable_data_base): Print out pattern-specific variables.
3024 * variable.h (struct variable): Remember when a variable is
3025 conditional. Also remember its flavor.
3026 (struct pattern_var): Instead of keeping a variable set, we just
3027 keep a single variable for each pattern.
3028 * read.c (record_target_var): Each pattern variable contains only a
3029 single variable, not a set, so create it properly.
3030 * doc/make.texi (Pattern-specific): Document the new behavior.
3032 2003-04-17 Paul D. Smith <psmith@gnu.org>
3034 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3035 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3036 file/directory naming rules for VMS so I can't tell whether this
3039 2003-04-09 Paul D. Smith <psmith@gnu.org>
3041 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3042 DOS-style pathnames: backslash separators and drive specifiers.
3044 2003-03-28 Paul D. Smith <psmith@gnu.org>
3046 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3047 the intermediate flag on all targets. Fixes bug #2515.
3049 2003-03-24 Paul D. Smith <psmith@gnu.org>
3051 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3052 Upgrade to autoconf 2.57 and automake 1.7.3.
3054 * job.c: More OS/2 changes from Andreas Buening.
3056 * file.c (print_file): Fix variable initialization.
3059 * remake.c (notice_finished_file):
3061 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3062 some calls (like readdir()) return NULL in valid situations
3063 without resetting errno. Fixes bug #2846.
3065 2003-02-25 Paul D. Smith <psmith@gnu.org>
3067 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3069 * job.c (_is_unixy_shell) [OS/2]: New function.
3070 Set default shell to /bin/sh.
3071 (reap_children): Close the job_rfd pipe here since we don't use a
3073 (set_child_handler_action_flags): define this to empty on OS/2.
3074 (start_job_command): Close the jobserver pipe and use
3075 child_execute_job() instead of fork/exec.
3076 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3077 rather than exec'ing, then reconfigure stdin/stdout.
3078 (exec_command): Rewrite to use spawn instead of exec. Return the
3081 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3082 in DOS. Handle the TEMP environment variable as in DOS. Don't
3083 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3084 use -j in DOS mode. Use child_execute_job() instead of
3087 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3090 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3091 prototypes that return values.
3093 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3095 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3096 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3098 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3101 2003-02-24 Paul D. Smith <psmith@gnu.org>
3103 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3104 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3105 (child_execute_job) [VMS]: Handle error status properly.
3106 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3108 * function.c (func_shell): Use EINTRLOOP() while reading from the
3109 subshell pipe (Fixes bug #2502).
3110 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3112 * main.c (main): Ditto.
3114 2003-01-30 Paul D. Smith <psmith@gnu.org>
3116 * read.c (eval): eval() was not fully reentrant, because the
3117 collapsed buffer was static. Change it to be an automatic
3118 variable so that eval() can be invoked recursively.
3120 (eval): Apply patch # 1022: fix memory reference error on long
3121 target-specific variable lines.
3122 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3124 * function.c (check_numeric): Combine the is_numeric() function
3125 into this function, since it's only called from one place.
3126 Constify this function. Have it print the incorrect string in the
3127 error message. Fixes bug #2407.
3128 (strip_whitespace): Constify.
3129 (func_if): Constify.
3130 * expand.c (expand_argument): Constify.
3132 2003-01-29 Paul D. Smith <psmith@gnu.org>
3134 Fix bug # 2169, also reported by other people on various systems.
3136 * make.h: Some systems, such as Solaris and PTX, do not fully
3137 implement POSIX-compliant SA_RESTART functionality; important
3138 system calls like stat() and readdir() can still fail with EINTR
3139 even if SA_RESTART has been set on the signal handler. So,
3140 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3141 EINTR for system calls which return -1 or 0 (NULL), respectively,
3143 Also, remove the old atomic_stat()/atomic_readdir() and
3144 HAVE_BROKEN_RESTART handling.
3146 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3148 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3149 * remake.c (touch_file): Ditto.
3151 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3152 * read.c (construct_include_path): Ditto.
3153 * remake.c (name_mtime): Ditto.
3154 * vpath.c (selective_vpath_search): Ditto.
3155 * dir.c (find_directory): Ditto.
3156 (local_stat): Ditto.
3157 (find_directory): Use ENULLLOOP() to wrap opendir().
3158 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3160 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3161 atomic_readdir() handling.
3163 2003-01-22 Paul D. Smith <psmith@gnu.org>
3165 * function.c (func_call): Fix Bug #1744. If we're inside a
3166 recursive invocation of $(call ...), mask any of the outer
3167 invocation's arguments that aren't used by this one, so that this
3168 invocation doesn't "inherit" them accidentally.
3170 2002-12-05 Paul D. Smith <psmith@gnu.org>
3172 * function.c (subst_expand): Valery Khamenia reported a
3173 pathological performance hit when doing substitutions on very
3174 large values with lots of words: turns out we were invoking
3175 strlen() a ridiculous number of times. Instead of having each
3176 call to sindex() call strlen() again, keep track of how much of
3177 the text we've seen and pass the length to sindex().
3179 2002-11-19 Paul D. Smith <psmith@gnu.org>
3181 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3184 2002-11-16 Paul D. Smith <psmith@gnu.org>
3186 * NMakefile.template (OBJS): Add hash.c object file.
3187 * SMakefile.template (srcs): Ditto.
3188 * Makefile.ami (objs): Ditto.
3189 * build_w32.bat: Ditto.
3191 * Makefile.DOS.template: Remove extra dependencies.
3193 2002-10-25 Paul D. Smith <psmith@gnu.org>
3195 * expand.c (install_variable_buffer): New function. Install a new
3196 variable_buffer context and return the previous one.
3197 (restore_variable_buffer): New function. Free the current
3198 variable_buffer context and put a previously saved one back.
3199 * variable.h: Prototypes for {install,restore}_variable_buffer.
3200 * function.c (func_eval): Push a new variable_buffer context
3201 before we eval, then restore the old one when we're done.
3204 * read.c (install_conditionals): New function. Install a new
3205 conditional context and return the previous one.
3206 (restore_conditionals): New function. Free the current
3207 conditional context and put a previously saved one back.
3208 (eval): Use the {install,restore}_conditionals for "include"
3210 (eval_buffer): Use {install,restore}_conditionals to preserve the
3211 present conditional state before we evaluate the buffer.
3214 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3216 (Recursion): Add a variable index entry for CURDIR.
3218 * README.cvs: Update to appropriate versions.
3219 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3220 don't need to copy loadavg.c: automake is smart enough to create
3221 it for me. Still have a bug in automake related to ansi2knr tho.
3223 2002-10-14 Paul D. Smith <psmith@gnu.org>
3225 * remake.c (notice_finished_file): Only touch targets if they have
3226 at least one command (as per POSIX). Resolve Bug #1418.
3228 * *.c: Convert to using ANSI C-style function definitions.
3229 * Makefile.am: Enable the ansi2knr feature of automake.
3230 * configure.in: ditto.
3232 2002-10-13 Paul D. Smith <psmith@gnu.org>
3234 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3235 for automatic variable values like $^, etc. In the case of very
3236 large lists of prerequisites this causes problems. Instead reuse
3237 a static buffer (resizeable) for each variable.
3239 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3240 target-specific variable definitions. Check for it and set an
3242 (record_target_var): Set the export field to v_export if the
3243 "exported" flag is set.
3244 * doc/make.texi (Target-specific): Document the ability to use
3247 * doc/make.texi: Change the name of the section on automatic
3248 variables from "Automatic" to "Automatic Variables". Added text
3249 clarifying the scope of automatic variables.
3251 2002-10-04 Paul D. Smith <psmith@gnu.org>
3253 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3255 (record_files): Ditto.
3257 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3258 the search for the '=' to only within the enclosing parens.
3260 2002-10-03 Paul D. Smith <psmith@gnu.org>
3262 Version 3.80 released.
3264 * dir.c: Change hash functions to use K&R function definition style.
3265 * function.c: Ditto.
3267 * variable.c: Ditto.
3269 Update to automake 1.7.
3271 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3272 (pdf): Remove this target as automake now provides one.
3274 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3276 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3278 * makefile.com: Updates for GNU make 3.80.
3279 * makefile.vms: Ditto.
3281 2002-09-23 Paul D. Smith <psmith@gnu.org>
3283 * read.c (enum make_word_type): Remove w_comment.
3284 (get_next_mword): Don't treat comment characters as special; where
3285 this function is used we will never see a comment (it's stripped
3286 before we get here) and treating comments specially means that
3287 targets like "foo\#bar" aren't handled properly.
3289 2002-09-18 Paul D. Smith <psmith@gnu.org>
3291 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3293 * read.c (eval): Expansion of arguments to export/unexport was
3294 ignoring all arguments after the first one. Change the algorithm
3295 to expand the whole line once, then parse the results.
3297 2002-09-17 Paul D. Smith <psmith@gnu.org>
3299 Fix Bug #940 (plus another bug I found while looking at this):
3301 * read.c (record_target_var): enter_file() will add a new entry if
3302 it's a double-colon target: we don't want to do that in this
3303 situation. Invoke lookup_file() and only enter_file() if it does
3304 not already exist. If the file we get back is a double-colon then
3305 add this variable to the "root" double-colon target.
3307 * variable.c (initialize_file_variables): If this file is a
3308 double-colon target but is not the "root" target, then initialize
3309 the root and make the root's variable list the parent of our
3312 2002-09-13 Paul D. Smith <psmith@gnu.org>
3314 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3316 * hash.c (round_up_2): Get rid of a warning.
3318 2002-09-12 Paul D. Smith <psmith@gnu.org>
3320 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3321 so it doesn't complain about getloadavg.c.
3323 * commands.c (set_file_variables): Make sure we always alloca() at
3324 least 1 character for the value of $? (for '\0').
3326 2002-09-11 Paul D. Smith <psmith@gnu.org>
3328 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3329 macro to use RESULT instead of the incorrect _RESULT_.
3331 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3332 and atomic_readdir(). We need to #include dirent.h to get this to
3334 * misc.c (atomic_readdir): Fix typos.
3336 2002-09-10 Paul D. Smith <psmith@gnu.org>
3338 * read.c (eval): Expand variable lists given to export and
3339 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3340 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3342 * doc/make.texi (Variables/Recursion): Document this.
3343 (Conditional Syntax): And here.
3345 2002-09-09 Paul D. Smith <psmith@gnu.org>
3347 * configure.in: Check for memmove().
3349 2002-09-07 Paul D. Smith <psmith@gnu.org>
3351 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3352 Michael Sterrett <msterret@coat.com> reports that while it has
3353 SA_RESTART, it does not work properly.
3355 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3356 that invokes stat() and loops to do it again if it returns EINTR.
3357 (atomic_readdir): Ditto, with readdir().
3359 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3360 and readdir() to atomic_stat() and atomic_readdir().
3362 2002-09-04 Paul D. Smith <psmith@gnu.org>
3364 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3365 reports that GNU make sometimes doesn't recognize that targets can
3366 be made, when directories can be created as prerequisites. He
3367 reports that changing the order of predicates in the DEP->changed
3368 flag test so that lookup_file() is always performed, solves this
3371 2002-08-08 Paul D. Smith <psmith@gnu.org>
3373 * configure.in: Require a newer version of gettext.
3375 * misc.c (perror_with_name): Translate the format string (for
3376 right-to-left language support).
3377 (pfatal_with_name): Ditto.
3379 * main.c: Create a static array of strings to store the usage
3380 text. This is done to facilitate translations.
3381 (struct command_switch): Remove argdesc and description fields.
3382 (switches): Remove values for obsolete fields.
3383 (print_usage): Print each element of the usage array.
3385 * hash.c: Change function definitions to be K&R style.
3387 2002-08-02 Paul D. Smith <psmith@gnu.org>
3389 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3390 this one because it's too hard to get right. We'll look at it for
3392 * main.c (main): Don't create the .TARGETS variable.
3393 * variable.c (handle_special_var): Don't handle .TARGETS.
3395 2002-08-01 Paul D. Smith <psmith@gnu.org>
3397 * main.c (switches): Add a new option, -B (--always-make). If
3398 specified, make will rebuild all targets that it encounters even
3399 if they don't appear to be out of date.
3400 (always_make_flag): New flag.
3401 * make.h: Extern always_make_flag.
3402 * remake.c (update_file_1): Check always_make_flag; if it's set we
3403 will always rebuild any target we can, even if none of its
3404 prerequisites are newer.
3407 * doc/make.texi (Shell Function): Make it clear that make
3408 variables marked as "export" are not passed to instances of the
3411 Add new introspection variable .VARIABLES and .TARGETS.
3413 * variable.c (handle_special_var): New function. If the variable
3414 reference passed in is "special" (.VARIABLES or .TARGETS),
3415 calculate the new value if necessary. .VARIABLES is handled here:
3416 walk through the hash of defined variables and construct a value
3417 which is a list of the names. .TARGETS is handled by
3418 build_target_list().
3419 (lookup_variable): Invoke handle_special_var().
3420 * file.c (build_target_list): Walk through the hask of known files
3421 and construct a list of the names of all the ones marked as
3423 * main.c (main): Initialize them to empty (and as simple variables).
3424 * doc/make.texi (Special Variables): Document them.
3425 * NEWS: Mention them.
3427 * variable.h (struct variable): Add a new flag "exportable" which
3428 is true if the variable name is valid for export.
3429 * variable.c (define_variable_in_set): Set "exportable" when a new
3430 variable is defined.
3431 (target_environment): Use the "exportable" flag instead of
3432 re-checking the name here... an efficiency improvement.
3434 2002-07-31 Paul D. Smith <psmith@gnu.org>
3436 * config.h-vms.template: Updates to build on VMS. Thanks to
3437 Brian_Benning@aksteel.com for helping verify the build.
3438 * makefile.com: Build the new hash.c file.
3439 * hash.h: Use strcpmi(), not stricmp(), in the
3440 HAVE_CASE_INSENSITIVE_FS case.
3442 2002-07-30 Paul D. Smith <psmith@gnu.org>
3444 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3445 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3446 Reported by <Brian_Benning@aksteel.com>.
3448 2002-07-10 Paul D. Smith <psmith@gnu.org>
3450 * variable.c (pop_variable_scope): Remove variable made unused by
3451 new hash infrastructure.
3452 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3453 comparisons as well as name comparisons.
3454 * variable.h: Add a prototype for new hash_init_function_table().
3455 * file.c (lookup_file): Remove variables made unused by new hash
3457 * dir.c (directory_contents_hash_2): Missing return of hash value.
3458 (dir_contents_file_exists_p): Remove variables made unused by new
3459 hash infrastructure.
3462 Installed Greg McGary's integration of the hash functions from the
3463 GNU id-utils package:
3465 2002-07-10 Greg McGary <greg@mcgary.org>
3467 * scripts/functions/filter-out: Add literals to to the
3468 pattern space in order to add complexity, and trigger
3469 use of an internal hash table. Fix documentation strings.
3470 * scripts/targets/INTERMEDIATE: Reverse order of files
3471 passed to expected `rm' command.
3473 2002-07-10 Greg McGary <greg@mcgary.org>
3475 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

3546 than a string constant, avoiding zillions of calls to strchr.
3547 Tighten inner search loops to test only for desired delimiters.

3565 2002-07-10 Paul D. Smith <psmith@gnu.org>
3567 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3568 prerequisite list. A real SysV make will expand the entire
3569 prerequisites list _twice_: we don't do that as it's a big
3570 backward-compatibility problem. We only replace those specific
3573 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3574 references left in the list of prerequisites. Check for .POSIX as
3575 we record targets, so we can disable non-POSIX behavior while
3576 reading makefiles as well as running them.
3577 (eval): Check the prerequisite list to see if we have anything
3578 that looks like a SysV prerequisite variable reference.
3580 2002-07-09 Paul D. Smith <psmith@gnu.org>
3582 * doc/make.texi (Prerequisite Types): Add a new section describing
3583 order-only prerequisites.
3585 * read.c (uniquize_deps): If we have the same file as both a
3586 normal and order-only prereq, get rid of the order-only prereq,
3587 since the normal one supersedes it.
3589 2002-07-08 Paul D. Smith <psmith@gnu.org>
3591 * AUTHORS: Added Greg McGary to the AUTHORS file.
3592 * NEWS: Blurbed order-only prerequisites.
3593 * file.c (print_file): Show order-only deps properly when printing
3596 * maintMakefile: Add "update" targets for wget'ing the latest
3597 versions of various external files. Taken from Makefile.maint in
3600 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3601 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3603 2002-07-07 Paul D. Smith <psmith@gnu.org>
3605 * po/*.po: Remove. We'll use wget to retrieve them at release
3608 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3609 rather than a shell you get an exception. Make sure we look up
3610 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3612 * remake.c (notice_finished_file): Fix handling of -t flag.
3613 Patch provided by Henning Makholm <henning@makholm.net>.
3615 * implicit.c (pattern_search): Some systems apparently run short
3616 of stack space, and using alloca() in this function caused an
3617 overrun. I modified it to use xmalloc() on the two variables
3618 which seemed like they might get large. Fixes Bug #476.
3620 * main.c (print_version): Update copyright notice to conform with
3622 (print_usage): Update help output.
3624 * function.c (func_eval): Create a new make function, $(eval
3625 ...). Expand the arguments, put them into a buffer, then invoke
3626 eval_buffer() on the resulting string.
3627 (func_quote): Create a new function, $(quote VARNAME). Inserts
3628 the value of the variable VARNAME without expanding it any
3631 * read.c (struct ebuffer): Change the linebuffer structure to an
3632 "eval buffer", which can be either a file or a buffer.
3633 (eval_makefile): Move the code in the old read_makefile() which
3634 located a makefile into here: create a struct ebuffer with that
3635 information. Have it invoke the new function eval() with that
3637 (eval_buffer): Create a new function that creates a struct ebuffer
3638 that holds a string buffer instead of a file. Have it invoke
3639 eval() with that ebuffer.
3640 (eval): New function that contains the guts of the old
3641 read_makefile() function: this function parses makefiles. Obtains
3642 data to parse from the provided ebuffer. Some modifications to
3643 make the flow of the function cleaner and clearer. Still could
3644 use some work here...
3645 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3646 contents of the define/endef variable from the ebuffer.
3647 (readstring): Read the next line from a string-style ebuffer.
3648 (readline): Read the next line from an ebuffer. If it's a string
3649 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3652 * dep.h (eval_buffer): Prototype eval_buffer();
3654 * variable.c (do_variable_definition): Make sure that all
3655 non-target-specific variables are registered in the global set.
3656 If we're invoked from an $(eval ...) we might be inside a $(call
3657 ...) or other function which has pushed a variable scope; we still
3658 want to define our variables from evaluated makefile code in the
3661 2002-07-03 Greg McGary <greg@mcgary.org>
3663 * dep.h (struct dep) [ignore_mtime]: New member.
3664 [changed]: convert to a bitfield.
3665 * implicit.c (pattern_search): Zero ignore_mtime.
3666 * main.c (main, handle_non_switch_argument): Likewise.
3667 * rule.c (convert_suffix_rule): Likewise.
3668 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3669 (read_makefile): Parse '|' in prerequisite list.
3670 (uniquize_deps): Consider ignore_mtime when comparing deps.
3671 * remake.c (update_file_1, check_dep): Don't force remake for
3672 dependencies that have d->ignore_mtime.
3673 * commands.c (FILE_LIST_SEPARATOR): New constant.
3674 (set_file_variables): Don't include a
3675 prerequisite in $+, $^ or $? if d->ignore_mtime.
3678 2002-06-18 Paul D. Smith <psmith@gnu.org>
3680 * make.texinfo: Updates for next revision. New date/rev/etc.
3681 Recreate all Info menus. Change license on the manual to the GNU
3682 Free Documentation License. A number of typos.
3683 (Variables Simplify): Don't use "-" before it's defined.
3684 (Automatic Prerequisites): Rewrite the target example to work
3685 properly if the compile fails. Remove incorrect comments about
3686 how "set -e" behaves.
3687 (Text Functions): Move the "word", "wordlist", "words", and
3688 "firstword" functions here, from "File Name Functions".
3689 * make-stds.texi: Update from latest GNU version.
3690 * fdl.texi: (created) Import the latest GNU version.
3692 2002-06-06 Paul D. Smith <psmith@gnu.org>
3694 * variable.c (do_variable_definition): New function: extract the
3695 part of try_variable_definition() that actually sets the value
3696 into a separate function.
3697 (try_variable_definition): Call do_variable_definition() after
3698 parsing the variable definition string.
3699 (define_variable_in_set): Make the name argument const.
3701 * variable.h (enum variable_flavor): Make public.
3702 (do_variable_definition): Create prototype.
3704 * read.c (read_all_makefiles): Create a new built-in variable,
3706 (read_makefile): Add each makefile read in to this variable value.
3708 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3710 * Makefile.DOS.template: Tweak according to changes in the
3711 distribution. Add back the dependencies of *.o files.
3713 * configh.dos.template: Synchronize with config.h.in.
3715 2002-05-09 Paul D. Smith <psmith@gnu.org>
3717 * file.c (file_timestamp_now): Use K&R function declaration.
3719 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3720 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3721 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3722 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3723 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3724 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3725 nlist.n_name is a pointer rather than an array.
3727 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3728 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3729 * configure.in: Use it instead of the old version.
3731 * main.c (main): Prefer setvbuf() to setlinebuf().
3733 2002-05-08 Paul D. Smith <psmith@gnu.org>
3735 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3736 (loadavg_LDADD): Ditto.
3738 2002-04-29 Paul D. Smith <psmith@gnu.org>
3740 * expand.c (recursively_expand_for_file): Rename
3741 recursively_expand() to recursively_expand_for_file() and provide
3742 an extra argument, struct file. If the argument is provided, set
3743 the variable scope to that of the file before expanding.
3744 * variable.h (recursively_expand): Make this a macro that invokes
3745 recursively_expand_for_file() with a NULL file pointer.
3746 * variable.c (target_environment): Call the renamed function and
3747 provide the current file context.
3748 Fixes Debian bug #144306.
3750 2002-04-28 Paul D. Smith <psmith@gnu.org>
3752 Allow $(call ...) user-defined variables to be self-referencing
3753 without throwing an error. Allows implementation of transitive
3754 closures, among other possibly useful things.
3755 Requested by: Philip Guenther <guenther@sendmail.com>
3757 * variable.h (struct variable): Add a new field: exp_count, and
3758 new macros to hold its size and maximum value.
3759 (warn_undefined): Make this a macro.
3760 * variable.c (define_variable_in_set): Initialize it.
3761 * expand.c (recursively_expand): If we detect recursive expansion
3762 of a variable, check the exp_count field. If it's greater than 0
3763 allow the recursion and decrement the count.
3764 (warn_undefined): Remove this (now a macro in variable.h).
3765 * function.c (func_call): Before we expand the user-defined
3766 function, modify its exp_count field to contain the maximum
3767 number of recursive calls we'll allow. After the call, reset it
3770 2002-04-21 Paul D. Smith <psmith@gnu.org>
3772 Modified to use latest autoconf (2.53), automake (1.6.1), and
3773 gettext (0.11.1). We're using gettext's new "external" support,
3774 to avoid including libintl source with GNU make.
3776 * README.cvs: New file. Explain how to build GNU make from CVS.
3778 * configure.in: Modify checking for the system glob library.
3779 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3780 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3781 etc. will manage it correctly). Set an automake conditional
3782 USE_LOCAL_GLOB to decide whether to compile the glob library.
3784 * getloadavg.c (main): Include make.h in the "TEST" program to
3787 * Makefile.am: Remove special rules for loadavg. Replace them
3788 with Automake capabilities for building extra programs.
3790 * signame.c: This file does nothing if the system provide
3791 strsignal(). If not, it implements strsignal(). If the system
3792 doesn't define sys_siglist, then we make our own; otherwise we use
3794 * signame.h: Removed.
3796 * main.c (main): No need to invoke signame_init(). Update copyright.
3798 * ABOUT-NLS: Removed.
3799 * gettext.c: Removed.
3800 * gettext.h: Get a simplified copy from the gettext package.
3802 * i18n/*.po: Moved to po/.
3805 * config/*: Created. Contains package configuration helper files.
3806 * config.guess, config.sub: Moved to config directory.
3808 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3809 Rework to use new-style autoconf features. Use the "external"
3810 mode for gettext. Make the build.sh config file conditional on
3811 whether build.sh.in exists, to avoid autoconf errors.
3812 * acinclude.m4: Removed almost all macros as being obsolete.
3813 Rewrote remaining macros to use AC_DEFINE.
3814 * acconfig.h: Removed.
3816 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3817 conditional to handle customs support. Remove special handling
3820 2002-04-20 Paul D. Smith <psmith@gnu.org>
3822 * function.c (func_call): Don't mark the argument variables $1,
3823 etc. as recursive. They've already been fully expanded so
3824 there's no need to do it again, and doing so strips escaped $'s.
3825 Reported by Sebastian Glita <glseba@yahoo.com>.
3827 * remake.c (notice_finished_file): Walk through double-colon
3828 entries via the prev field, not the next field!
3829 Reported by Greg McGary <greg@mcgary.org>.
3831 * main.c (main): If the user specifies -q and asks for a specific
3832 target which is a makefile, we got an assert. In that case it
3833 turns out we should continue normally instead.
3835 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3837 * i18n/he.po: Installed a new translation.
3839 2002-01-07 Paul D. Smith <psmith@gnu.org>
3841 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3843 2001-12-04 Paul D. Smith <psmith@gnu.org>
3845 * i18n/ja.po: Installed an updated translation.
3847 2001-09-06 Paul Eggert <eggert@twinsun.com>
3849 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3850 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3852 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3854 (main): Get rid of any avoidable limit on stack size.
3856 2001-09-04 Paul D. Smith <psmith@gnu.org>
3858 * i18n/da.po: Installed an updated translation.
3860 2001-08-03 Paul D. Smith <psmith@gnu.org>
3862 * i18n/fr.po: Installed an updated translation.
3863 Resolves Debian bug #106720.
3865 2001-06-13 Paul D. Smith <psmith@gnu.org>
3867 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3870 2001-06-11 Paul D. Smith <psmith@gnu.org>
3872 * i18n/ko.po: Installed a new translation.
3874 2001-05-06 Paul D. Smith <psmith@gnu.org>
3876 Modify the EINTR handling.
3878 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3879 the way in which we manage the file descriptor/signal handler race
3880 trap to be more efficient.
3882 2001-05-06 Paul Eggert <eggert@twinsun.com>
3884 Restart almost all system calls that are interrupted, instead
3885 of worrying about EINTR. The lone exception is the read() for
3888 * configure.in (HAVE_SA_RESTART): New macro.
3889 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3890 * main.c (main): Use SA_RESTART instead of the old,
3891 nonstandard SA_INTERRUPT.
3893 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3894 * main.c (bsd_signal): New function or macro,
3895 if the implementation doesn't supply it.
3896 (The bsd_signal function will be in POSIX 1003.1-200x.)
3897 (HANDLESIG): Remove.
3898 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3900 * make.h (EINTR_SET): Remove.
3901 (SA_RESTART): New macro.
3903 * arscan.c (ar_member_touch): Don't worry about EINTR.
3904 * function.c (func_shell): Likewise.
3905 * job.c (reap_children, free_child, new_job): Likewise.
3906 * main.c (main): Likewise.
3907 * remake.c (touch_file, name_mtime): Likewise.
3909 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3910 if fstat failed with errno!=EINTR, the error was ignored.
3912 * job.c (set_child_handler_action_flags): New function.
3913 (new_job): Use it to temporarily clear the SIGCHLD action flags
3914 while reading the token.
3916 2001-05-02 Paul D. Smith <psmith@gnu.org>
3918 * job.c (start_job_command): Don't add define/endef per-line flags
3919 to the top-level flags setting.
3921 2001-04-03 Paul D. Smith <psmith@gnu.org>
3923 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3924 bit on error, so check for odd return values, not non-0 return
3926 (VMS_get_member_info): Calculate the timezone differences correctly.
3927 Reported by John Fowler <jfowler@nyx.net>.
3930 2001-03-14 Paul D. Smith <psmith@gnu.org>
3932 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3933 value before invoking define_variable().
3934 Reported by John Fowler <jfowler@nyx.net>.
3936 2001-02-07 Paul D. Smith <psmith@gnu.org>
3938 * read.c (record_target_var): If we reset the variable due to a
3939 command-line variable setting overriding it, turn off the "append"
3942 2001-01-17 Paul D. Smith <psmith@gnu.org>
3944 * variable.c (lookup_variable) [VMS]: When getting values from the
3945 environment, allocate enough space for the _value_ plus escapes,
3946 not enough space for the name plus escapes :-/.
3947 Reported by John Fowler <jfowler@nyx.net>.
3949 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3950 warnings that make generates, so it doesn't look like an error.
3951 Reported by Karl Berry <karl@gnu.org>.
3954 Fix for PR/2020: Rework appended target-specific variables. I'm
3955 fairly confident this algorithm is finally correct.
3957 * expand.c (allocated_variable_append): Rewrite. Instead of
3958 expanding each appended variable then adding all the expanded
3959 strings together, we append all the unexpanded values going up
3960 through the variable set contexts, then expand the final result.
3961 This behaves just like non-target-specific appended variable
3962 values, while the old way didn't in various corner cases.
3963 (variable_append): New function: recursively append the unexpanded
3964 value of a variable, walking from the outermost variable scope to
3966 * variable.c (lookup_variable): Remove the code that looked up the
3967 variable set list if the found variable was "append". We don't
3969 (lookup_variable_in_set): Make this non-static so we can use it
3971 (try_variable_definition): Use lookup_variable_in_set() rather
3972 than faking out current_variable_set_list by hand (cleanup).
3973 * variable.h: Add a prototype for the now non-static
3974 lookup_variable_in_set().
3976 2000-11-17 Paul D. Smith <psmith@gnu.org>
3978 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3979 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3980 before throwing a fit.
3982 2000-11-17 Paul D. Smith <psmith@gnu.org>
3984 * read.c (readline): CRLF calculations had a hole, if you hit the
3985 buffer grow scenario just right. Reworked the algorithm to avoid
3986 the need for len or lastlen at all. Problem description with
3987 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3989 2000-10-24 Paul D. Smith <psmith@gnu.org>
3991 * gettext.c (SWAP): Declare this with the prototype, otherwise
3992 some systems don't work (non-32-bit? Reported for Cray T3E).
3993 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3995 2000-10-05 Paul D. Smith <psmith@gnu.org>
3997 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3998 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4000 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4002 2000-09-22 Paul D. Smith <psmith@gnu.org>
4004 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4005 parts of the real gettext.h here, and we expect to really include
4006 the real gettext.h later. If we keep this #define, it's ignored.
4008 2000-09-21 Paul D. Smith <psmith@gnu.org>
4010 * main.c (log_working_directory): Rework the text to use complete
4011 sentences, to make life simpler for the translators.
4013 2000-08-29 Paul D. Smith <psmith@gnu.org>
4015 * file.c (remove_intermediates): Print a debug message before we
4016 remove intermediate files, so the user (if she uses -d) knows
4019 2000-08-21 Paul D. Smith <psmith@gnu.org>
4021 * variable.c (try_variable_definition): Change how we handle
4022 target-specific append variable defns: instead of just setting the
4023 value, expand it as an append _but_ only within the current
4024 target's context. Otherwise we lose all but the last value if the
4025 variable is appended more than once within the current target
4026 context. Fixes PR/1831.
4028 2000-08-16 Paul D. Smith <psmith@gnu.org>
4030 * function.c (func_shell): Nul-terminate the buffer before
4031 printing an exec error message (just in case it's not!).
4032 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4034 2000-07-25 Paul D. Smith <psmith@gnu.org>
4036 * job.c (construct_command_argv_internal): Add "~" to the list of
4037 sh_chars[] which disallow optimizing out the shell call.
4039 2000-07-23 Paul Eggert <eggert@twinsun.com>
4041 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4042 supersedes --disable-nsec-timestamps.
4043 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4044 * README: Remove --disable-nsec-timestamps.
4046 * filedef.h (struct file.low_resolution_time): New member.
4047 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4048 * remake.c (update_file_1):
4049 Avoid spurious rebuilds due to low resolution time stamps,
4050 generalizing the earlier code that applied only to archive members.
4051 (f_mtime): Archive members always have low resolution time stamps.
4053 * configure.in: Remove --disable-nsec-timestamps, as this has
4054 been superseded by .LOW_RESOLUTION_TIME.
4056 2000-07-23 Paul Eggert <eggert@twinsun.com>
4058 * configure.in (enable_nsec_timestamps): Renamed from
4059 make_cv_nsec_timestamps, since enable/disable options
4060 shouldn't be cached.
4062 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4063 and Paul Eggert <eggert@twinsun.com>
4065 * file.c (file_timestamp_now):
4066 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4067 so that clock_gettime is not linked unless needed.
4069 * filedef.h (FILE_TIMESTAMP_HI_RES):
4070 Remove definition; "configure" now does this.
4072 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4073 to before high resolution file timestamp check,
4074 since that check now uses uintmax_t.
4075 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4076 high resolution file timestamps.
4077 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4078 so that we don't link in clock_gettime unnecessarily.
4080 2000-07-17 Paul D. Smith <psmith@gnu.org>
4082 * i18n/ja.po: New version of the translation file.
4084 2000-07-07 Paul D. Smith <psmith@gnu.org>
4086 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4087 the offset calculation.
4088 (name_mtime): Replace EINTR test with EINTR_SET macro.
4090 2000-07-07 Paul Eggert <eggert@twinsun.com>
4094 * remake.c (update_file_1):
4095 Avoid spurious rebuilds of archive members due to their
4096 timestamp resolution being only one second.
4097 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4098 the clock's resolution being lower than file timestamps'.
4099 When warning about future timestamps, report only the discrepancy,
4100 not the absolute value of the timestamp and the current time.
4102 * file.c (file_timestamp_now): New arg RESOLUTION.
4103 * filedef.h (file_timestamp_now): Likewise.
4104 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4106 2000-07-05 Paul D. Smith <psmith@gnu.org>
4108 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4109 to listp. Fixes PR/1793.
4111 2000-06-26 Paul Eggert <eggert@twinsun.com>
4113 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4115 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4117 * remake.c (f_mtime): Remove unused var memtime.
4119 2000-06-25 Martin Buchholz <martin@xemacs.org>
4121 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4122 Ran spell-check on make.texinfo.
4124 2000-06-23 Paul D. Smith <psmith@gnu.org>
4126 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4127 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4128 * make.h: Define these macros.
4130 * Version 3.79.1 released.
4132 * configure.in: Add a new option, --disable-nsec-timestamps, to
4133 avoid using sub-second timestamps on systems that support it. It
4134 can lead to problems, e.g. if your makefile relies on "cp -p".
4135 * README.template: Document the issue with "cp -p".
4137 * config.guess, config.sub: Updated.
