550 -I switch to look in ./ instead of ./doc.
551 (html): Target depend on html-recursive instead of make_1.html.
552 (make_1.html): Removed.
553 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
554 (all-recursive): Allow for more than one subdir in the build
556 (mostlyclean-recursive, clean-recursive, distclean-recursive)
557 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
558 (tags-recursive): Allow for more than one subdir in the build
560 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
561 targets. Enter into doc/ to produce the targets.
562 (all-am): $(INFO_DEPS) replaced by info.
564 2009-09-26 Paul Smith <psmith@gnu.org>
566 * read.c (record_files): Use free_ns() to free struct nameseq.
569 * rule.c (freerule): Use free_dep_chain().
571 * read.c (record_files): Free FILENAMES chain for implicit rules.
572 (eval): Static pattern targets go into the string cache.
574 * function.c (string_glob): Free NAME in the nameseq chain.
576 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
578 * implicit.c (pattern_search): Terminate early if we haven't
579 found any rules to try (performance improvement).
581 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
583 * implicit.c (pattern_search): Merge three parallel arrays,
584 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
585 of struct TRYRULE. In the old version the latter two arrays
586 had insufficient length.
588 2009-09-24 Paul Smith <psmith@gnu.org>
590 * implicit.c (pattern_search): Add back support for order-only
591 prerequisites for secondary expansion implicit rules, that were
592 accidentally dropped. If we find a "|", enable order-only mode
593 and set IGNORE_MTIME on all deps that are seen afterward.
594 (pattern_search): Fix memory leaks: for intermediate files where
595 we've already set the file variable and pattern variable sets, be
596 sure to either save or free them as appropriate.
598 2009-09-23 Paul Smith <psmith@gnu.org>
600 Rework the way secondary expansion is stored, for efficiency.
601 This changes secondary expansion so that ONLY WHEN we know we have
602 a possibility of needing secondary expansion, do we defer the
603 secondary expansion. This means more parsing the deps but we use
604 a lot less memory (due to the strcache). Also, this fixes
607 * read.c (eval): Don't parse the dep string here anymore.
608 (record_files): Take the dep argument as an unparsed string. If
609 secondary expansion is enabled AND the prereq string has a '$' in
610 it, then set NEED_2ND_EXPANSION and keep the entire string.
611 Otherwise, parse the dep string here to construct the dep list
612 with the names in the strcache.
614 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
615 duplicate the name string (others are in the strcache).
617 * implicit.c: Remove struct idep and free_idep_chain(): unused.
618 (struct patdeps): New structure to store prereq information.
619 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
620 which prerequisites need expansion, and expand only those.
622 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
623 and enter_prereqs(). split_prereqs() takes a fully-expanded string
624 and splits it into a DEP list, handling order-only prereqs.
625 (enter_prereqs): This function enters a list of DEPs into the file
626 database. If there's a stem defined, expand any pattern chars.
627 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
628 set. Use the above functions.
629 (snap_deps): Only perform second expansion on prereqs that need it,
630 as defined by the NEED_2ND_EXPANSION flag.
631 (print_prereqs): New function to print the prereqs
632 (print_file): Call print_prereqs() rather than print inline.
634 * hash.h (STRING_COMPARE): Take advantage of strcache() by
636 (STRING_N_COMPARE): Ditto.
637 (ISTRING_COMPARE): Ditto.
639 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
640 (parse_file_seq): Return void*
641 * read.c (parse_file_seq): Return void*.
642 (eval): Invoke macroized version of parse_file_seq()
643 * default.c (set_default_suffixes): Ditto.
644 * file.c (split_prereqs): Ditto.
645 * function.c (string_glob): Ditto.
646 * main.c (main): Ditto.
647 * rule.c (install_pattern_rule): Ditto.
649 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
651 2009-09-16 Paul Smith <psmith@gnu.org>
653 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
655 * dep.h: Create alloc_dep() / free_dep() macros.
657 * implicit.c (pattern_search): Take advantage of the new
658 parse_file_seq() to add the directory prefix to each prereq.
660 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
661 all. Avoid reversing chains. Support adding prefixes.
662 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
663 cached/non-cached results.
664 (eval): Remove multi_glob() & invoke new parse_file_seq().
665 * rule.c (install_pattern_rule): Ditto.
666 * main.c (main): Ditto.
667 * implicit.c (pattern_search): Ditto.
668 * function.c (string_glob): Ditto.
669 * file.c (parse_prereqs): Ditto.
670 * default.c (set_default_suffixes): Ditto.
672 * variable.c (parse_variable_definition): Don't run off the end of
673 the string if it ends in whitespace (found with valgrind).
675 * commands.c (set_file_variables): Keep space for all targets in
676 $? if -B is given (found with valgrind).
678 2009-09-15 Paul Smith <psmith@gnu.org>
680 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
681 (xcalloc): Add new function.
682 * make.h: New declarations.
684 * ar.c (ar_glob_match): New calling method for concat().
685 * main.c (main): Ditto.
686 (decode_env_switches): Ditto.
687 * read.c (eval_makefile): Ditto.
688 (tilde_expand): Ditto.
689 (parse_file_seq): Ditto.
690 * variable.c (target_environment): Ditto.
691 (sync_Path_environment): Ditto.
693 * ar.c (ar_glob_match): Use xcalloc().
694 * dir.c (file_impossible): Ditto.
695 * file.c (enter_file): Ditto.
696 * job.c (new_job): Ditto.
697 * read.c (parse_file_seq): Ditto.
698 * vmsfunctions.c (opendir): Ditto.
700 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
702 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
703 inside the loop that looks up environment for PATH.
705 2009-08-31 Eli Zaretskii <eliz@gnu.org>
707 * function.c (windows32_openpipe): Update envp after calling
708 sync_Path_environment.
710 2009-08-02 Paul Smith <psmith@gnu.org>
712 * remake.c (notice_finished_file): Ensure file->cmds is not null
713 before looping through them. Fixes Savannah bug #21824.
715 * doc/make.texi (Wildcard Examples): Clarify when objects is
716 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
717 (Include): Clarify the behavior of -include.
718 Fixes Savannah bug #18963.
720 2009-08-01 Paul Smith <psmith@gnu.org>
722 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
723 etc. come on the command line. Fixes Savannah bug #27093.
725 * expand.c (expand_argument): If the argument is large enough use
726 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
728 * variable.c (do_variable_definition): Avoid using alloca() to
729 hold values, which can be large. Fixes Savannah bug #23960.
731 * job.c (new_job): Use memmove() instead of strcpy() since both
732 pointers are in the same memory block. Fixes Savannah bug #27148.
733 Patch by Petr Machata.
735 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
737 * job.c (construct_command_argv_internal): Add "ulimit" and
738 "unset" to the sh_cmds for Unixy shells.
740 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
742 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
743 that set make_cv_sys_gnu_glob, so they are also correctly set
744 when the cache has been populated before.
746 2009-07-04 Eli Zaretskii <eliz@gnu.org>
748 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
749 exist, as realpath(3) does where it's supported.
751 2006-07-04 Eli Zaretskii <eliz@gnu.org>
753 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
754 (abspath): Support systems that define HAVE_DOS_PATHS (have
755 drive letters in their file names). Use IS_PATHSEP instead of a
756 literal '/' comparison. Fixes Savannah bug #26886.
758 2009-06-14 Paul Smith <psmith@gnu.org>
760 * remake.c (update_file_1): Remember the original file we marked
761 as updating, so we can clear that flag again. If we find a target
762 via vpath, FILE might change.
763 (check_dep): Ditto. Fixes Savannah bug #13529.
764 Patch by Reid Madsen <reid.madsen@tek.com>.
766 2009-06-13 Paul Smith <psmith@gnu.org>
768 * doc/make.texi (MAKEFILES Variable): Be explicit that files
769 included by MAKEFILES cannot give default goals.
770 * read.c (eval): If set_default is not set, pass the no-default-goal
771 value when we read included makefiles. Fixes Savannah bug #13401.
773 * ar.c (ar_name): Ensure that targets with empty parens aren't
774 considered archive member references: archive members must have a
775 non-empty "member" string. Fixes Savannah bug #18435.
777 * function.c (string_glob): Rely on multi_glob() to determine
778 whether files exist or not. Remove call to file_exists_p() which
779 is not always correct. Fixes Savannah bug #21231.
780 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
781 then only files that really exist will be returned.
782 * dep.h: Add new argument to multi_glob().
783 * rule.c (install_pattern_rule): Ditto.
784 * read.c (eval): Ditto.
785 * main.c (main): Ditto.
786 * implicit.c (pattern_search): Ditto.
787 * file.c (parse_prereqs): Ditto.
788 * default.c (set_default_suffixes): Ditto.
790 2009-06-09 Paul Smith <psmith@gnu.org>
792 * commands.c (set_file_variables): If always_make_flag is set,
793 always add the prereq to $?. Fixes Savannah bug #17825.
795 * remake.c (update_file_1): When rebuilding deps of FILE, also try
796 to rebuild the deps of all the also_make targets for that file.
797 Fixes Savannah bug #19108.
799 * implicit.c (pattern_search): Undo test for is_target, added by
800 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
801 Rule Search Algorithm". Fixes Savannah bug #17752.
803 * main.c (clean_jobserver): Clear the jobserver_fds options and
804 set job_slots to the default when we clean up.
805 (define_makeflags): Return the new MAKEFLAGS value.
806 (main): Reset MAKEFLAGS in the environment when we re-exec.
807 Fixes Savannah bug #18124.
809 2009-06-08 Paul Smith <psmith@gnu.org>
811 * read.c (eval): Collapse continuations post-semicolon on target-
812 specific variables. Fixes Savannah bug #17521.
814 2009-06-07 Paul Smith <psmith@gnu.org>
816 * job.c (reap_children): For older systems without waitpid() (are
817 there any of these left?) run wait(2) inside EINTRLOOP to handle
818 EINTR errors. Fixes Savannah bug #16401.
820 * (various): Debug message cleanup. Fixes Savannah bug #16469.
822 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
824 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
825 not the end, to catch second expansion $(eval ...) defining new
826 target/prereq relationships during snap_deps.
827 Fixes Savannah bug #24622.
829 * read.c (record_files): The second-expansion "f->updating" hack
830 was not completely correct: if assumed that the target with
831 commands always had prerequisites; if one didn't then the ordering
832 was messed up. Fixed for now to use f->updating to decide whether
833 to preserve the last element in the deps list... but this whole
834 area of constructing and reversing the deps list is too confusing
835 and needs to be reworked. Fixes Savannah bug #21198.
837 2009-06-06 Paul Smith <psmith@gnu.org>
839 * hash.c (hash_insert): Remove useless test for NULL.
840 Fixes Savannah bug #21823.
842 * make.h: Move SET_STACK_SIZE determination to make.h.
843 * main.c (main): New global variable, STACK_LIMIT, holds the
844 original stack limit when make was started.
845 * job.c (start_job_command): Reset the stack limit, if we changed it.
846 Fixes Savannah bug #22010.
848 * remake.c (check_dep): Only set the target's state to not-started
849 if it's not already running. Found this while testing -j10 builds
850 of glibc: various targets were being rebuilt multiple times.
851 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
854 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
855 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
858 2009-06-04 Paul Smith <psmith@gnu.org>
860 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
862 * maintMakefile: Modify access of config and gnulib Savannah
863 modules to use GIT instead of CVS.
865 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
866 Fixes Savannah bug #24655.
868 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
869 this can happen during some invocations of $(eval ...) for example.
870 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
872 2009-06-02 Paul Smith <psmith@gnu.org>
874 * configure.in: Check for fileno()
875 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
876 for the makefile file so invocations of $(shell ...) don't inherit it.
877 Fixes Savannah bug #24277.
879 2009-06-01 Paul Smith <psmith@gnu.org>
881 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
882 expansion was handled incorrectly. Rework the default goal
883 handling to save the variable only. Remove default_goal_file and
885 * read.c (eval): Check default_goal_var, not default_goal_name.
886 * read.c (record_target_var): Don't check default_goal_file here.
888 2009-05-31 Paul Smith <psmith@gnu.org>
890 * main.c (main): Expand the .DEFAULT_GOAL variable before using
891 it, and if the multi_glob() returns nothing (say it expanded to
892 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
894 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
895 $(and ..) to the reference. Fixes Savannah bug #25694.
897 * make.1: Be clear that some recipes will be executed even with -n.
898 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
900 * doc/make.texi (Override Directive): Make more clear how
901 overrides and appends interact.
902 Elucidates part of Savannah bug #26207.
904 * read.c (record_target_var): Don't reset the origin on
905 target-specific variables; try_variable_definition() will handle
906 this correctly. Fixes Savannah bug #26207.
908 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
909 Fixes Savannah bug #25712.
911 * implicit.c (pattern_search): Keep a pointer to the beginning of
912 the filename and save that instead of the constructed pointer.
913 Fixes Savannah bug #26593.
914 Patch by Mark Seaborn <mrs@mythic-beasts.com>
916 2009-05-30 Paul Smith <psmith@gnu.org>
918 * doc/make.texi (Multi-Line): Add a description of the new abilities
919 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
920 "command sequence" vs. "recipe" syntax.
921 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
922 after a define, to create variables with those flavors.
924 2009-05-25 Paul Smith <psmith@gnu.org>
926 Reworked the parser for variable assignments to allow multiple
927 modifiers, and in any order. Also allows variable and
928 prerequisites to be modifier names ('export', 'private', etc.)
930 * NEWS: Add notes about user-visible changes.
932 * read.c (struct vmodifiers): Remember what modifiers were seen.
933 (parse_var_assignment): New function to parse variable assignments.
934 (eval): Call the new function. Handle variable assignments earlier.
936 * variable.c (parse_variable_definition): Only parse; don't create var.
937 (assign_variable_definition): Call parse, then create the var.
939 2009-05-24 Paul Smith <psmith@gnu.org>
941 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
942 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
944 2009-03-14 Eli Zaretskii <eliz@gnu.org>
946 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
947 Fixes Savannah bug #25412.
949 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
950 prototype for xmalloc.
951 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
952 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
953 Loop over an array of extensions, instead of duplicating the same
954 code inline. Use SearchPath followed by CreateFile, instead of
955 the obsolete OpenFile. Fixes Savannah bug #17277.
956 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
957 to `find_file'. Fixes Savannah bug #25662.
959 2009-03-07 Eli Zaretskii <eliz@gnu.org>
961 * function.c (func_shell): Don't close pipedes[1] if it is -1.
962 Fixes Savannah bug #20495.
964 2009-02-28 Ralf Wildenhues <address@hidden>
966 * doc/make.texi (Instead of Execution): Document interaction of
967 -t with phony targets.
969 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
971 Introduce a new keyword "private" which applies to target-specific
972 variables and prevents their values from being inherited.
974 * variable.h (struct variable): Add private_var flag to each variable.
975 Add a flag to specify which list entry switches to the parent target.

1002 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1004 * job.c (construct_command_argv_internal): Avoid extra backslash
1005 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1008 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1010 * README.W32.template: Remove obsolete text about non-support for
1011 -jN without Unixy shell. Remove obsolete text about not supplying
1012 Visual Studio project files (we do supply them). Modify text to
1013 prefer GCC builds to MSC builds.
1015 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1017 * doc/make.texi (Empty Targets): Fix typo.
1019 2008-03-27 Paul Smith <psmith@gnu.org>

1032 `value' field is NULL.
1034 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1036 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1038 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1039 (TEXINFOS): Value changed to `doc/make.texi'.
1040 (.SUFFIXES): Use .texi instead of .texinfo.
1041 (make.info, make.dvi): Depend on doc/make.texi.
1042 (.texi.info): New target, instead of ".texinfo.info". Change -I
1043 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1044 (.texi): New target, instead of ".texinfo". Change -I switch to
1045 $(MAKEINFO) to look in doc/. Use --no-split.
1046 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1047 switch to $(MAKEINFO) to look in doc/.
1048 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1049 "*.i[0-9][0-9]" (due to --no-split above).
1050 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1051 (html, make_1.html): New targets.
1052 (.PHONY): Add "html".
1053 (.SUFFIXES): Add .html.
1055 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1057 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1058 HAVE_DECL_SYS_SIGLIST.
1060 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1061 build does not use child_execute_job.
1063 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1064 export the SHELL environment variable to the child.
1066 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1088 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1090 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1091 a more complex value than a simple shell: if it's not a default
1092 shell now then expand it and see if is a default shell then.
1094 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1096 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1097 pathnames, with const strings.

1103 * make.h: Add a prototype for w32_kill() (change suggested by

1118 2007-09-11 Paul Smith <psmith@gnu.org>
1120 * doc/make.texi (Special Variables): Moved this into the "How to
1121 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1125 (Simple Makefile): Ditto.
1126 (Rule Syntax): Ditto.
1127 (Command Syntax): Ditto.
1128 (Error Messages): Ditto.
1130 2007-09-10 Paul Smith <psmith@gnu.org>
1132 * commands.c (print_commands): Don't print an extra line in the
1133 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1135 * read.c (construct_include_path): Add the full string to the cache; we
1136 were chopping the last char.
1138 * NEWS: Announce the .RECIPEPREFIX special variable.
1139 * variable.c (lookup_special_var): Rename from handle_special_var().
1140 (lookup_variable): Call the new name.
1141 (set_special_var): New function: handle setting of special variables.
1142 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1145 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1146 * main.c (main): Create the .RECIPEPREFIX special variable.
1147 * read.c (eval): Remove the cmd_prefix characters from the command
1148 scripts here, so they're not stored in the commands array at all,
1149 rather than waiting and stripping them out during command construction.
1150 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1152 2007-08-15 Paul Smith <psmith@gnu.org>
1154 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1155 file has had the section info removed, so add some to make.texi
1156 before we include it.
1158 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1160 * remake.c (check_dep): Reset the target state for intermediate
1161 files. They might have been considered before but not updated

1176 2007-07-13 Paul Smith <psmith@gnu.org>
1178 * file.c (expand_deps): Use variable_buffer as the start of the
1179 buffer, not the original pointer (in case it was reallocated).
1180 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1181 Fixes Savannah bug #20452.

1218 Dave Korn <dave.korn@artimi.com>
1220 2007-05-08 Paul Smith <psmith@gnu.org>
1222 Fix Savannah bug #19656:
1224 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1226 * make.h: Change all case-insensitive string compares to use
1227 strcasecmp() (from POSIX). If we don't have that but do have one
1228 of the others, define strcasecmp to be one of those instead. If
1229 we don't have any, declare a prototype for our own version.
1231 * misc.c (strcasecmp): Use this if we can't find any native
1232 case-insensitive string comparison function.
1233 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1234 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1236 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1237 strcasecmp() instead of stricmp().
1238 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1239 instead of strcmpi().
1240 * acinclude.m4: Remove the strcasecmp() check from here.
1242 2007-03-21 Paul Smith <psmith@gnu.org>
1244 * configure.in: Don't turn on case-insensitive file system support
1245 if --disable-... is given. Fixes Savannah bug #19348.
1247 2007-03-19 Paul Smith <psmith@gnu.org>
1249 * ALL: Use the strcache for all file name strings, or other
1250 strings which we will never free. The goal is to save memory by
1251 avoiding duplicate copies of strings. However, at the moment this
1252 doesn't save much memory in most situations: due to secondary
1253 expansion we actually save prerequisite lists twice (once before
1254 the secondary expansion, and then again after it's been parsed
1255 into individual file names in the dep list). We will resolve this
1256 in a future change, by doing the parsing up-front for targets
1257 where secondary expansion is not set.
1259 Moving things into the strcache also allows us to use const
1260 pointers in many more places.
1262 2007-01-03 Paul Smith <psmith@gnu.org>
1264 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1265 the function, not just the first. Fixes Savannah bug #18680.
1267 2006-11-18 Paul Smith <psmith@gnu.org>
1269 * strcache.c (strcache_add_len): Don't allocate a new buffer
1270 unless the string is not already nil-terminated. Technically this
1271 is a violation of the standard, since we may be passed an array
1272 that is not long enough to test one past. However, in make this
1273 is never true since we only use nil-terminated strings or
1274 sub-strings thereof.
1276 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1278 * main.c: New global cmd_prefix, defaults to '\t'.
1279 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1282 * dir.c: Constified.
1283 (dir_contents_file_exists_p): Check for an error return from
1284 readdir(), just in case.
1286 * commands.c: Constified.
1287 * default.c: Constified.
1288 * expand.c: Constified.
1289 * function.c: Partial constification.

1294 * w32/pathstuff.c: Partial constification.
1296 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1298 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1299 backslashes and drive letters as absolute.
1301 2006-10-22 Paul Smith <psmith@gnu.org>

1305 2006-10-21 Paul Smith <psmith@gnu.org>
1308 * arscan.c: Constified.
1310 2006-09-30 Paul Smith <psmith@gnu.org>
1312 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1313 point to lastword since the example was updated.
1314 Fixes Savannah bug #16304.
1315 (Secondary Expansion): Correct example description.
1316 Fixes Savannah bug #16468.
1317 (Makefile Contents): Clarify that comments cannot appear within
1318 variable references or function calls.
1319 Fixes Savannah bug #16577.
1320 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1321 Fixes Savannah bug #17701.
1322 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1324 prerequisites. Fixes Savannah bug #17880.
1325 (Rule Syntax): "lise" -> "list"
1326 (Multiple Rules): ... -> @dots{}
1327 (Splitting Lines): ditto.
1329 * remake.c (update_file_1): Prereqs that don't exist should be
1330 considered changed, for the purposes of $?.
1331 Fixes Savannah bug #16051.
1333 * make.1: Remove extraneous "+".
1334 Fixes Savannah bug #16652.

1370 2006-04-20 Paul D. Smith <psmith@gnu.org>
1372 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1373 that don't have extended grep.
1374 (cvsclean): Use $(PERL) instead of perl.
1376 2006-04-09 Paul D. Smith <psmith@gnu.org>
1378 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1380 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1381 inner-scope variables don't mask outer-scope variables.
1383 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1384 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:

1386 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1387 values from memory allocation functions: they return void* and so
1388 don't need to be cast. Also remove (char *) casts of arguments to

1403 2006-04-06 Paul D. Smith <psmith@gnu.org>
1405 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we

1442 Declare and define sh_chars_sh[].
1444 2006-03-23 Paul D. Smith <psmith@gnu.org>
1446 * configure.in: Look for build.sh.in in $srcdir so it will be
1447 built for remote configurations as well.
1449 * Makefile.am: Make sure to clean up build.sh during distclean.
1450 Fixes Savannah bug #16166.
1452 * misc.c (log_access): Takes a const char *.

1468 make sure I don't forget any).
1470 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1472 (die): Cleanup code was removed from here; call the new function.
1473 (main): If we are re-execing, clean up the jobserver first so we
1474 don't leak file descriptors.

1488 (free_dep_chain): Use free_dep.
1489 * read.c (record_files): Store stem in the dependency line.

1504 Fixes Savannah bug #15913.
1506 2006-03-09 Paul Smith <psmith@gnu.org>
1508 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1509 listed non-existent files as changed. Turns out there's a bug in
1510 the Linux kernel builds which means that this change causes
1511 everything to rebuild every time. We will re-introduce this fix
1512 in the next release, to give them time to fix their build system.
1513 Fixes Savannah bug #16002.
1514 Introduces Savannah bug #16051.

1534 string values to avoid memory leaks.
1536 * expand.c (recursively_expand_for_file): Only set reading_file to
1537 an initialized value.
1539 * implicit.c (pattern_search): We need to make a copy of the stem
1540 if we get it from an intermediate dep, since those get freed.
1542 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1544 (enter_file) [VMS]: Ditto.

1549 * job.c (construct_command_argv_internal): Fix last change.
1551 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1552 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1553 the calls to _beginthreadex.
1555 * expand.c (recursively_expand_for_file): Initialize `save' to
1556 prevent compiler warnings.
1558 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1560 * job.c (construct_command_argv_internal): Don't create a temporary

1562 script file stream to text mode.

1566 * variable.c (merge_variable_set_lists): Don't try to merge the
1567 global_setlist. Not only is this useless, but it can lead to
1568 circularities in the linked list, if global_setlist->next in one
1569 list gets set to point to another list which also ends in

1575 Fix for Savannah bug #106.

1578 expanding. If no variable is being expanded, it's the same as
1580 * make.h (expanding_var): Declare it.
1581 * expand.c (recursively_expand_for_file): Set expanding_var to the
1582 current variable we're expanding, unless there's no file info in
1583 it (could happen if it comes from the command line or a default
1584 variable). Restore it before we exit.

1599 * implicit.c (pattern_search): If we allocated a variable set for
1600 an impossible file, free it.
1601 * variable.c (free_variable_set): New function.
1602 * variable.h: Declare it.
1604 * read.c (read_all_makefiles): Makefile names are kept in the
1605 strcache, so there's never any need to alloc/free them.
1608 * main.c (main): Add "archives" to the .FEATURES variable if
1609 archive support is enabled.
1610 * doc/make.texi (Special Variables): Document it.

1620 * (ALL FILES): Updated copyright and license notices.
1622 2006-02-10 Paul D. Smith <psmith@gnu.org>
1624 A new internal capability: the string cache is a read-only cache
1625 of strings, with a hash table interface for fast lookup. Nothing
1626 in the cache will ever be freed, so there's no need for reference
1627 counting, etc. This is the beginning of a full solution for
1628 Savannah bug #15182, but for now we only store makefile names here.
1630 * strcache.c: New file. Implement a read-only string cache.
1631 * make.h: Add prototypes for new functions.
1632 * main.c (initialize_global_hash_tables): Initialize the string cache.
1633 (print_data_base): Print string cache stats.
1634 * read.c (eval_makefile): Use the string cache to store makefile
1635 names. Rewrite the string allocation to be sure we free everything.
1637 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1639 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1640 directory time stamp didn't change, except on FAT filesystems.

1643 2006-02-09 Paul D. Smith <psmith@gnu.org>
1645 * function.c (func_or): Implement a short-circuiting OR function.
1646 (func_and): Implement a short-circuiting AND function.
1647 (function_table_init): Update the table with the new functions.
1648 * doc/make.texi (Conditional Functions): Changed the "if" section
1649 to one on general conditional functions. Added documentation for
1650 $(and ...) and $(or ...) functions.
1651 * NEWS: Note new $(and ...) and $(or ...) functions.
1653 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1655 * job.h (struct child): Add the dontcare bitfield.
1656 * job.c (new_job): Cache dontcare flag.
1657 * job.c (reap_children): Use cached dontcare flag instead of the
1658 one in struct file. Fixes Savannah bug #15641.
1660 2006-02-06 Paul D. Smith <psmith@gnu.org>
1662 * vpath.c (selective_vpath_search): If the file we find has a
1663 timestamp from -o or -W, use that instead of the real time.
1664 * remake.c (f_mtime): If the mtime is a special token from -o or
1665 -W, don't overwrite it with the real mtime.
1666 Fixes Savannah bug #15341.
1668 Updates from Markus Mauhart <qwe123@chello.at>:
1670 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1682 to avoid walking the list every time we want to add a new one.
1683 Fixes Savannah bug #15533.
1684 * filedef.h (struct file): Add a new LAST pointer.
1686 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1687 the comparison. For 64-bits systems the result of the subtraction
1688 might not fit into an int. Use comparison instead.
1689 Fixes Savannah bug #15534.
1691 * doc/make.texi: Update the chapter on writing commands to reflect
1692 the changes made in 3.81 for backslash/newline and SHELL handling.

1712 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1714 * remake.c (update_goal_chain): Set g->changed instead of
1715 incrementing it, as it is only 8-bit wide, and could overflow if
1716 many commands got started in update_file.
1718 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1720 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1721 MAXIMUM_WAIT_OBJECTS.
1722 (process_wait_for_any_private): Change dimension of handles[]
1723 array to MAXIMUM_WAIT_OBJECTS.

1725 (process_register): Don't register more processes than the
1726 available number of slots.
1727 (process_easy): Don't start new processes if all slots are used up.
1729 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1730 are already more children than sub_proc.c can handle, behave as if
1731 the load were too high.
1732 (start_job_command): Fix a typo in error message when process_easy
1735 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1737 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1738 the shell is not sh.exe.
1740 * job.c (create_batch_file): Renamed from create_batch_filename;
1741 all callers changed. Don't close the temporary file; return its
1742 file descriptor instead. New arg FD allows to return the file
1744 (construct_command_argv_internal): Use _fdopen instead of fopen to
1745 open the batch file.
1747 2006-01-04 Paul D. Smith <psmith@gnu.org>
1749 * readme.vms: Updates for case-insensitive VMS file systems from
1750 Hartmut Becker <Hartmut.Becker@hp.com>.

1770 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1771 disable warnings for MSC.
1772 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1774 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1776 * doc/make.texi (Execution): Add a footnote about changes in
1777 handling of backslash-newline sequences. Mention the differences
1778 on MS-DOS and MS-Windows.
1780 * NEWS: More details about building the MinGW port and a pointer
1781 to README.W32. Fix the section name that describes the new
1782 backward-incompatible processing of backslash-newline sequences.
1783 The special processing of SHELL set to "cmd" is only relevant to
1784 MS-Windows, not MS-DOS.
1786 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1788 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1789 to DWORD, to avoid compiler warnings.
1790 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1791 use %ld in format, to avoid compiler warnings.
1793 * doc/make.texi (Special Targets): Fix a typo.
1794 (Appending): Fix cross-reference to Setting.
1795 (Special Variables, Secondary Expansion, File Name Functions)
1796 (Flavor Function, Pattern Match, Quick Reference): Ensure two

1805 * read.c (record_target_var): Initialize variable's export field
1806 with v_default instead of leaving it "initialized" by whatever
1807 garbage happened to be on the heap.
1809 2005-12-12 Paul D. Smith <psmith@gnu.org>
1811 * make.1: Fix some display errors and document all existing options.
1812 Patch by Mike Frysinger <vapier@gentoo.org>.
1814 2005-12-11 Paul D. Smith <psmith@gnu.org>
1816 * implicit.c (pattern_search): If 2nd expansion is not set for
1817 this implicit rule, replace the pattern with the stem directly,
1818 and don't re-expand the variable list. Along with the other
1819 .SECONDEXPANSION changes below, fixes bug #13781.
1821 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1823 * implicit.c (pattern_search): Mark other files that this rule
1824 builds as targets so that they are not treated as intermediates
1825 by the pattern rule search algorithm. Fixes bug #13022.
1827 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1829 * remake.c (notice_finished_file): Propagate the change of
1830 modification time to all the double-colon entries only if

1849 * read.c (record_files): Don't set deps flags if there are no deps.
1850 * maintMakefile: We only need to build the templates when we are
1851 creating a distribution, so don't do it for "all".
1853 2005-10-24 Paul D. Smith <psmith@gnu.org>
1855 Make secondary expansion optional: its enabled by declaring the
1856 special target .SECONDEXPANSION.
1858 * NEWS: Update information on second expansion capabilities.
1859 * doc/make.texi (Secondary Expansion): Document the
1860 .SECONDEXPANSION special target and its behavior.
1861 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1862 prerequisite list was found in a static pattern rule.
1863 (free_dep_chain): Declare a prototype.
1864 * file.c (parse_prereqs): New function: break out some complexity
1866 (expand_deps): If we aren't doing second expansion, replace % with
1867 the stem for static pattern rules. Call the new function.
1868 * filedef.h (parse_prereqs): Declare a prototype.
1869 * implicit.c (pattern_search): Initialize the new staticpattern
1871 * main.c (second_expansion): Declare a global variable to remember
1872 if the special target has been seen. Initialize the new
1873 staticpattern field for prerequisites.
1874 * make.h: Extern for second_expansion.
1875 * misc.c (free_dep_chain): New function: frees a struct dep list.
1876 * read.c (read_all_makefiles): Initialize the staticpattern field.
1877 (eval_makefile): Ditto.
1878 (record_files): Check for the .SECONDEXPANSION target and set
1879 second_expansion global if it's found.
1880 Use the new free_dep_chain() instead of doing it by hand.
1881 Set the staticpattern field for prereqs of static pattern targets.
1883 2005-10-16 Paul D. Smith <psmith@gnu.org>
1885 * main.c (main): Set CURDIR to be a file variable instead of a
1886 default, so that values of CURDIR inherited from the environment
1887 won't override the make value.
1889 2005-09-26 Paul D. Smith <psmith@gnu.org>
1891 * job.c (construct_command_argv_internal): If the line is empty
1892 remember to free the temporary argv strings.
1895 2005-09-16 Paul D. Smith <psmith@gnu.org>
1897 * job.c (start_job_command): The noerror flag is a boolean (single
1898 bit); set it appropriately.
1899 Reported by Mark Eichin <eichin@metacarta.com>
1901 2005-08-29 Paul D. Smith <psmith@gnu.org>
1903 * function.c (func_error): On Windows, output from $(info ...)
1904 seems to come in the wrong order. Try to force it with fflush().
1906 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1908 * read.c (record_files): Move code that sets stem for static
1909 pattern rules out of the if (!two_colon) condition so it is
1910 also executed for two-colon rules. Fixes Savannah bug #13881.
1912 2005-08-08 Paul D. Smith <psmith@gnu.org>
1914 * make.h: Don't test that __STDC__ is non-0. Some compilers
1915 (Windows for example) set it to 0 to denote "ISO C + extensions".
1918 2005-08-07 Paul D. Smith <psmith@gnu.org>
1920 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1921 conditional (slightly different version of a fix from Eli).
1923 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1924 If make is running in parallel without -k and two jobs die in a
1925 row, but not too close to each other, then make will quit without
1926 waiting for the rest of the jobs to die.
1928 * main.c (die): Don't reset err before calling reap_children() the
1929 second time: we still want it to be in the error condition.
1930 * job.c (reap_children): Use a static variable, rather than err,
1931 to control whether or not the error message should be printed.
1933 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1935 * w32/subproc/sub_proc.c: Include signal.h.
1936 (process_pipe_io, process_file_io): Pass a pointer to a local
1937 DWORD variable to GetExitCodeProcess. If the exit code is
1938 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1940 * job.c [WINDOWS32]: Include windows.h.
1941 (main_thread) [WINDOWS32]: New global variable.
1942 (reap_children) [WINDOWS32]: Get the handle for the main thread
1943 and store it in main_thread.
1945 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1946 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1947 doing anything else. When we are done, close the main thread
1948 handle and exit with status 130.
1950 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1952 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1955 * main.c (find_and_set_default_shell): If found a DOSish shell,
1956 set sh_found and the value of default_shell, and report the
1957 findings in debug mode.
1959 * job.c (construct_command_argv_internal): Check unixy_shell, not
1960 no_default_sh_exe, to decide whether to use Unixy or DOSish
1963 * README.W32: Update with info about the MinGW build.
1965 * build_w32.bat: Support MinGW.
1967 * w32/subproc/build.bat: Likewise.
1969 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1970 printing DWORD args.
1972 * function.c (windows32_openpipe): Fix format strings for printing
1975 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1977 (start_job_command): Fix format string for printing the result of
1979 (start_job_command) [WINDOWS32]: Do not define.
1980 (exec_command): Fix format string for printing HANDLE args.
1982 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1983 to avoid compiler warnings.
1984 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1985 (Note: some of these fixes were submitted independently by J. Grant)

1989 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1990 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1991 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1993 2005-07-15 Paul Smith <psmith@gnu.org>
1995 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1996 we don't have a POSIX shell, then revert to the old
1997 backslash-newline behavior (where they are stripped).
2000 2005-07-08 Paul D. Smith <psmith@gnu.org>
2002 * config.h.W32.template: Reorder to match the standard config.h,
2003 for easier comparisons.
2004 From J. Grant <jg@jguk.org>
2006 * maintMakefile: Remove .dep_segment before overwriting it, in
2007 case it's not writable or noclobber is set.
2008 * expand.c (variable_expand_string): Cast result of pointer
2009 arithmetic to avoid a warning.
2010 * main.c (switches): Add full-fledged final initializer.
2012 2005-07-06 Paul D. Smith <psmith@gnu.org>
2014 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2015 * signame.c (strsignal): If we found _sys_siglist[] or
2016 __sys_siglist[] use those instead of sys_siglist[].
2017 From Albert Chin <china@thewrittenword.com>
2019 2005-07-04 Paul D. Smith <psmith@gnu.org>
2021 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2022 globfree(); set up to use the GNU versions.
2023 From Martin Zinser <zinser@zinser.no-ip.info>
2025 2005-07-03 Paul D. Smith <psmith@gnu.org>
2027 From J. Grant <jg@jguk.org>:

2033 * w32/subproc/build.bat: Ditto.
2035 2005-06-28 Paul D. Smith <psmith@gnu.org>
2037 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2038 declaration was checked but not present.
2040 2005-06-27 Paul D. Smith <psmith@gnu.org>
2042 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2043 to unsigned long. Fixes Savannah bug #13550.
2045 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2046 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2047 Fixes Savannah bug #13551.
2049 2005-06-26 Paul D. Smith <psmith@gnu.org>
2051 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2052 it if ANSI_STRING is not set.
2054 2005-06-25 Paul D. Smith <psmith@gnu.org>
2056 * read.c (eval): If no filenames are passed to any of the
2057 "include" variants, don't print an error.
2058 * doc/make.texi (Include): Document this.
2059 Fixes Savannah bug #1761.
2061 * job.c (construct_command_argv_internal): Sanitize handling of
2062 backslash/newline pairs according to POSIX: that is, keep the
2063 backslash-newline in the command script, but remove a following
2064 TAB character, if present. In the fast path, make sure that the
2065 behavior matches what the shell would do both inside and outside
2066 of quotes. In the slow path, quote the backslash and put a
2067 literal newline in the string.
2068 Fixes Savannah bug #1332.
2069 * doc/make.texi (Execution): Document the new behavior and give
2071 * NEWS: Make a note of the new behavior.
2073 * make.h [WINDOWS32]: #include <direct.h>.
2074 Fixes Savannah bug #13478.
2076 * remake.c (name_mtime): If the stat() of a file fails and the -L
2077 option was given and the file is a symlink, take the best mtime of
2078 the symlink we can get as the mtime of the file and don't fail.
2079 Fixes Savannah bug #13280.
2081 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2082 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2083 inside a variable reference. Make this function static as it's
2085 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2086 parsing an unexpanded line looking for semicolons.
2087 Fixes Savannah bug #1454.
2088 * misc.c (remove_comments): Move this to read.c and make it static
2089 as it's only used there. Call find_char_unquote() with new arg.
2090 * make.h: Remove prototypes for find_char_unquote() and
2091 remove_comments() since they're static now.
2093 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2094 its export flag and obtain its value. When we need to re-exec,
2095 increment the value and add it into the environment.
2096 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2097 * NEWS: Mention MAKE_RESTARTS.
2098 * main.c (always_make_set): New variable. Change the -B option to
2099 set this one instead.
2100 (main): When checking makefiles, only set always_make_flag if
2101 always_make_set is set AND the restarts flag is 0. When building
2102 normal targets, set it IFF always_make_set is set.
2103 (main): Avoid infinite recursion with -W, too: only set what-if
2104 files to NEW before we check makefiles if we've never restarted
2105 before. If we have restarted, set what-if files to NEW _after_ we
2107 Fixes Savannah bug #7566:
2109 2005-06-17 Paul D. Smith <psmith@gnu.org>
2111 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2112 in the prerequisites list.
2114 2005-06-12 Paul D. Smith <psmith@gnu.org>
2116 Fix Savannah bug # 1328.
2118 * configure.in: Check for atexit().
2119 * misc.c (close_stdout): Test stdout to see if writes to it have
2120 failed. If so, be sure to exit with a non-0 error code. Based on
2121 code found in gnulib.
2122 * make.h: Prototype.
2123 * main.c (main): Install close_stdout() with atexit().
2125 2005-06-10 Paul D. Smith <psmith@gnu.org>
2127 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2129 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2130 headers; make vmsWaitForChildren() static; extern vmsify().
2131 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2132 Don't create child_execute_job() here (it's in vmsjobs.c).
2133 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2135 2005-06-09 Paul D. Smith <psmith@gnu.org>
2137 * variable.c (push_new_variable_scope): File variables point
2138 directly to the global_setlist variable. So, inserting a new
2139 scope in front of that has no effect on those variables: they
2140 don't go through current_variable_set_list. If we're pushing a
2141 scope and the current scope is global, push it "the other way" so
2142 that the new setlist is in the global_setlist variable, and
2143 next points to a new setlist with the global variable set.
2144 (pop_variable_scope): Properly undo a push with the new
2146 Fixes Savannah bug #11913.
2148 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2150 * job.c (reap_children): Don't die of the command failed but
2151 the dontcare flag is set. Fixes Savannah bug #13216.
2153 * implicit.c (pattern_search): When creating a target from
2154 an implicit rule match, lookup pattern target and set precious
2155 flag in a newly created target. Fixes Savannah bug #13218.
2157 2005-05-13 Paul D. Smith <psmith@gnu.org>
2159 Implement "if... else if... endif" syntax.
2161 * read.c (eval): Push all checks for conditional words ("ifeq",
2162 "else", etc.) down into the conditional_line() function.
2163 (conditional_line): Rework to allow "else if..." clause. New
2164 return value -2 for lines which are not conditionals. The
2165 ignoring flag can now also be 2, which means "already parsed a
2166 true branch". If that value is seen no other branch of this
2167 conditional can be considered true. In the else parsing if there
2168 is extra text after the else, invoke conditional_line()
2169 recursively to see if it's another conditional. If not, it's an
2170 error. If so, raise the conditional value to this level instead
2171 of creating a new conditional nesting level. Special check for
2172 "else" and "endif", which aren't allowed on the "else" line.
2173 * doc/make.texi (Conditional Syntax): Document the new syntax.
2175 2005-05-09 Paul D. Smith <psmith@gnu.org>
2177 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2178 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2179 recurses to the w32 directory, even on non-Windows systems. Use
2180 the method suggested in the automake manual.
2181 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2182 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2184 2005-05-07 Paul D. Smith <psmith@gnu.org>
2186 * main.c (die): If we're dying with a fatal error (not that a
2187 command has failed), write back any leftover tokens before we go.
2189 * job.c (set_child_handler_action_flags): If there are jobs
2190 waiting for the load to go down, set an alarm to go off in 1
2191 second. This allows us to wake up from a potentially long-lasting
2192 read() and start a new job if the load has gone down. Turn it off
2194 (job_noop): Dummy signal handler function.
2195 (new_job): Invoke it with the new semantics.
2197 * docs/make.texi: Document secondary expansion. Various cleanups
2200 2005-05-03 Paul D. Smith <psmith@gnu.org>
2202 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2203 the targets which are to ultimately be made are called "goals";
2204 see the GNU make manual. Also, MAKECMDGOALS, etc.
2206 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2207 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2208 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2210 2005-05-02 Paul D. Smith <psmith@gnu.org>
2212 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2213 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2214 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2215 functions to vmsjobs.c. #include it into jobs.c.
2217 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2218 jobserver tokens. I found that this happens when an exported
2219 recursive variable contains a $(shell ...) function reference: in
2220 this situation we could "forget" to write back a token.
2222 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2223 we have. It's not reliable to depend on the number of children in
2224 our linked list so keep a separate count.
2225 (new_job): Check jobserver_tokens rather than children &&
2226 waiting_jobs. Increment jobserver_tokens when we get one.
2227 (free_child): If jobserver_tokens is 0, internal error. If it's
2228 >1, write a token back to the jobserver pipe (we don't write a
2229 token for the "free" job). Decrement jobserver_tokens.
2231 * main.c: Add variable master_job_slots.
2232 (main): Set it to hold the number of jobs requested if we're the
2233 master process, when using the jobserver.
2234 (die): Sanity checks: first test jobserver_tokens to make sure
2235 this process isn't holding any tokens we didn't write back.
2236 Second, if master_job_slots is set count the tokens left in the
2237 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2239 2005-04-24 Paul D. Smith <psmith@gnu.org>
2241 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2242 with -l# can lose jobserver tokens, because waiting jobs are not
2243 consulted properly when checking for the "free" token.
2245 * job.c (free_child): Count waiting_jobs as having tokens.
2246 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2247 handle jobs waiting for the load to drop.
2249 2005-04-23 Paul D. Smith <psmith@gnu.org>
2251 * main.c (main): Be careful to not core if a variable setting in
2252 the environment doesn't contain an '='. This is illegal but can
2253 happen in broken setups.
2254 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2256 2005-04-12 Paul D. Smith <psmith@gnu.org>
2258 The second expansion feature causes significant slowdown. Timing
2259 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2260 read the makefile before the feature, to 11+s to do the same
2261 operations after the feature. Additionally, memory usage
2262 increased drastically. To fix this I added some intelligence that
2263 avoids the overhead of the second expansion unless it's required.
2265 * dep.h: Add a new boolean field, need_2nd_expansion.
2267 * read.c (eval): When creating the struct dep for the target,
2268 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2269 (record_files): If there's a "%" in a static pattern rule, it gets
2270 converted to "$*" so set need_2nd_expansion to 1.
2272 * file.c (expand_deps): Rework to be more efficient. Only perform
2273 initialize_file_variables(), set_file_variables(), and
2274 variable_expand_for_file() if the need_2nd_expansion is set.
2276 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2277 (pattern_search): Ditto.
2278 * main.c (handle_non_switch_argument): Ditto.
2280 * read.c (read_all_makefiles): Ditto.
2281 (eval_makefile): Ditto.
2283 2005-04-07 Paul D. Smith <psmith@gnu.org>
2285 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2286 * variable.c (sync_Path_environment): Ditto.
2287 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2289 * main.c (main): Define the .FEATURES variable.
2290 * NEWS: Announce .FEATURES.
2291 * doc/make.texi (Special Variables): Document .FEATURES.
2293 * remake.c (check_dep): If a file is .PHONY, update it even if
2294 it's marked intermediate. Fixes Savannah bug #12331.
2296 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2298 * file.c (expand_deps): Factor out the second expansion and
2299 prerequisite line parsing logic from snap_deps().
2301 * file.c (snap_deps): Use expand_deps(). Expand and parse
2302 prerequisites of the .SUFFIXES special target first. Fixes
2303 Savannah bug #12320.
2305 2005-03-13 Paul D. Smith <psmith@gnu.org>
2307 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2310 2005-03-11 Paul D. Smith <psmith@gnu.org>
2312 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2313 available, not undefined (from Earnie Boyd).
2315 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2317 * implicit.c (pattern_search): Mark an intermediate target as
2318 precious if it happened to be a prerequisite of some (other)
2319 target. Fixes Savannah bug #12267.
2321 2005-03-09 Paul D. Smith <psmith@gnu.org>
2323 * read.c (eval_makefile): Add alloca(0).
2324 (eval_buffer): Ditto.
2326 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2328 * main.c (main): Use o_file instead of o_default when defining
2329 the .DEFAULT_TARGET special variable.
2330 * read.c (eval): Use define_variable_global() instead of
2331 define_variable() when setting new value for the .DEFAULT_TARGET
2332 special variable. Fixes Savannah bug #12266.
2334 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2336 * imlicit.c (pattern_search): Mark files for which an implicit
2337 rule has been found as targets. Fixes Savannah bug #12202.
2339 2005-03-04 Paul D. Smith <psmith@gnu.org>
2342 * doc/make.texi (Automatic Variables): Document $|.
2344 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2346 * read.c (record_files): Instead of substituting % with
2347 actual stem value in dependency list replace it with $*.
2348 This fixes stem triple expansion bug.
2350 * implicit.c (pattern_search): Copy stem to a separate
2351 buffer and make it a properly terminated string. Assign
2352 this buffer instead of STEM (which is not terminated) to
2353 f->stem. Instead of substituting % with actual stem value
2354 in dependency list replace it with $*. This fixes stem
2355 triple expansion bug.
2357 2005-03-01 Paul D. Smith <psmith@gnu.org>
2359 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2360 on Windows, as it takes a handle not a pid. Just exit.
2361 Fix from patch #3679, provided by Alessandro Vesely.
2363 * configure.in: Update check for sys_siglist[] from autoconf manual.
2364 * signame.c (strsignal): Update to use the new autoconf macro.
2366 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2368 * read.c (record_files): Add a check for the list of prerequisites
2369 of a static pattern rule being empty. Fixes Savannah bug #12180.
2371 2005-02-28 Paul D. Smith <psmith@gnu.org>
2373 * doc/make.texi (Text Functions): Update docs to allow the end
2374 ordinal for $(wordlist ...) to be 0.
2375 * function.c (func_wordlist): Fail if the start ordinal for
2376 $(wordlist ...) is <1. Matches documentation.
2377 Resolves Savannah support request #103195.
2379 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2380 previously we were stopping when !-q, exactly the opposite. This
2381 has been wrong since version 1.34, in 1994!
2382 (update_file): If we got an error don't break out to run more
2383 double-colon rules: just return immediately.
2384 Fixes Savannah bug #7144.
2386 2005-02-27 Paul D. Smith <psmith@gnu.org>
2388 * misc.c (end_of_token): Make argument const.
2389 * make.h: Update prototype.
2391 * function.c (abspath, func_realpath, func_abspath): Use
2392 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2393 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2394 * read.c (record_files): Ditto.
2395 * variable.c (do_variable_definition): Ditto.
2397 * function.c (func_error): Create a new function $(info ...) that
2398 simply prints the message to stdout with no extras.
2399 (function_table_init): Add new function to the table.
2400 * NEWS: Add $(info ...) reference.
2401 * doc/make.texi (Make Control Functions): Document it.
2403 New feature: if the system supports symbolic links, and the user
2404 provides the -L/--check-symlink-time flag, then use the latest
2405 mtime between the symlink(s) and the target file.
2407 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2408 readlink(). If both are available, define MAKE_SYMLINKS.
2409 * main.c: New variable: check_symlink_flag.
2410 (usage): Add a line for -L/--check-symlink-times to the help string.
2411 (switches): Add -L/--check-symlink-times command line argument.
2412 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2413 print a warning and disable it again.
2414 * make.h: Declare check_symlink_flag.
2415 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2416 if the file is a symlink then check each link in the chain and
2417 choose the NEWEST mtime we find as the mtime for the file. The
2418 newest mtime might be the file itself!
2419 * NEWS: Add information about this new feature.
2420 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2422 Avoid core dumps described in Savannah bug # 12124:
2424 * file.c: New variable snapped_deps remember whether we've run
2426 (snap_deps): Set it.
2427 * filedef.h: Extern it.
2428 * read.c (record_files): Check snapped_deps; if it's set then
2429 we're trying to eval a new target/prerequisite relationship from
2430 within a command script, which we don't support. Fatal.
2432 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2434 Implementation of the .DEFAULT_TARGET special variable.
2436 * read.c (eval): If necessary, update default_target_name when
2438 * read.c (record_files): Update default_target_file if
2439 default_target_name has changed.
2440 * main.c (default_target_name): Define.
2441 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2442 default_target_name is set use default_target_file as a root
2444 * filedef.h (default_target_name): Declare.
2445 * dep.h (free_dep_chain):
2446 * misc.c (free_dep_chain): Change to operate on struct nameseq
2447 and change name to free_ns_chain.
2448 * file.c (snap_deps): Update to use free_ns_chain.
2450 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2452 Implementation of the second expansion in explicit rules,
2453 static pattern rules and implicit rules.
2455 * read.c (eval): Refrain from chopping up rule's dependencies.
2456 Store them in a struct dep as a single dependency line. Remove
2457 the code that implements SySV-style automatic variables.
2459 * read.c (record_files): Adjust the code that handles static
2460 pattern rules to expand all percents instead of only the first
2461 one. Reverse the order in which dependencies are stored so that
2462 when the second expansion reverses them again they appear in
2463 the makefile order (with some exceptions, see comments in
2464 the code). Remove the code that implements SySV-style automatic
2467 * file.c (snap_deps): Implement the second expansion and chopping
2468 of dependency lines for explicit rules.
2470 * implicit.c (struct idep): Define an auxiliary data type to hold
2471 implicit rule's dependencies after stem substitution and
2474 * implicit.c (free_idep_chain): Implement.
2476 * implicit.c (get_next_word): Implement helper function for
2477 parsing implicit rule's dependency lines into words taking
2478 into account variable expansion requests. Used in the stem
2481 * implicit.c (pattern_search): Implement the second expansion
2482 for implicit rules. Also fixes bug #12091.
2484 * commands.h (set_file_variables): Declare.
2485 * commands.c (set_file_variables): Remove static specifier.
2487 * dep.h (free_dep_chain): Declare.
2488 * misc.c (free_dep_chain): Implement.
2490 * variable.h (variable_expand_for_file): Declare.
2491 * expand.c (variable_expand_for_file): Remove static specifier.
2493 * make.h (strip_whitespace): Declare.
2494 * function.c (strip_whitespace): Remove static specifier.
2496 2005-02-26 Paul D. Smith <psmith@gnu.org>
2498 * main.c (main): Check for ferror() when reading makefiles from stdin.
2499 Apparently some shells in Windows don't close pipes properly and
2502 2005-02-24 Jonathan Grant <jg@jguk.org>
2504 * configure.in: Add MinGW configuration options, and extra w32 code
2506 * Makefile.am: Add MinGW configuration options, and extra w32 code
2508 * main.c: Determine correct program string (after last \ without .exe).
2509 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2511 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2512 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2513 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2514 environment support.
2516 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2518 * function.c (func_shell): When initializing error_prefix, check
2519 that reading file name is not null. This fixes long-standing
2520 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2522 2005-02-09 Paul D. Smith <psmith@gnu.org>
2524 * maintMakefile: Update the CVS download URL to simplify them.
2525 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2526 downloading the .texi files from Savannah now.
2528 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2530 * main.c (handle_non_switch_argument): Only add variables to
2531 command_variables if they're not already there: duplicate settings
2532 waste space and can be confusing to read.
2534 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2535 this header is never included by non-WINDOWS32 code, and it
2536 requires <config.h> to define which isn't always included first.
2538 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2539 testing MINGW32 versions.
2541 * main.c (log_working_directory): flush stdout to be sure the WD
2542 change is printed before any stderr messages show up.
2544 2005-02-01 Paul D. Smith <psmith@gnu.org>
2546 * maintMakefile (po_repo): Update the GNU translation site URL.
2548 2004-12-01 Paul D. Smith <psmith@gnu.org>
2550 * main.c (main): Change char* env_shell to struct variable shell_var.
2551 * variable.c (target_environment): Use new shell_var.
2553 2004-11-30 Paul D. Smith <psmith@gnu.org>
2555 * configure.in: The old way we avoided creating build.sh from
2556 build.sh.in before build.sh.in exists doesn't work anymore; we
2557 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2558 the help!). This also keeps automake from complaining.
2559 * Makefile.am (README): Add a dummy target so automake won't
2560 complain that this file doesn't exist when we checkout from CVS.
2561 * maintMakefile (.dep_segment): Rewrite this rule since newer
2562 versions of automake don't provide DEP_FILES.
2564 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2566 Implementation of `realpath' and `abspath' built-in functions.
2568 * configure.in: Check for realpath.
2569 * function.c (abspath): Return an absolute file name that does
2570 not contain any `.' or `..' components, nor repeated `/'.
2571 * function.c (func_abspath): For each name call abspath.
2572 * function.c (func_realpath): For each name call realpath
2573 from libc or delegate to abspath if realpath is not available.
2574 * doc/make.texi (Functions for File Names): Document new functions.
2575 * doc/make.texi (Quick Reference): Ditto.
2577 2004-11-28 Paul D. Smith <psmith@gnu.org>
2579 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2580 arguments. Fixes bug #10252.
2582 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2584 * main.c (main): Set SHELL to v_noexport by default. Remember the
2585 original environment setting of SHELL in the env_shell variable.
2586 * main.h: Export new env_shell variable.
2587 * variable.c (target_environment): If we find a v_noexport
2588 variable for SHELL, add a SHELL variable with the env_shell value.
2589 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2590 * doc/make.texi (Variables/Recursion): Ditto.
2592 2004-11-28 Paul D. Smith <psmith@gnu.org>
2594 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2595 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2596 Patch by Alessandro Vesely.
2598 2004-11-12 Paul D. Smith <psmith@gnu.org>
2600 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2601 the command line if it's inside a string.
2602 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2604 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2606 * function.c (func_lastword): New function: return last word
2607 from the list of words.
2608 * doc/make.texi: Document $(lastword ). Fix broken links in
2609 Quick Reference section.
2611 2004-10-06 Paul D. Smith <psmith@gnu.org>
2613 Apply patch from Alessandro Vesely, provided with bug # 9748.
2614 Fix use of tmpnam() to work with Borland C.
2616 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2617 construction of a temporary filename, and call new function
2618 create_batch_filename().
2619 (create_batch_filename) [WINDOWS32]: New function to create a
2622 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2624 * read.c (record_target_var): Expand simple pattern-specific
2626 * variable.c (initialize_file_variables): Do not expand simple
2627 pattern-specific variable.
2629 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2631 * remake.c (update_file_1): When rebuilding makefiles inherit
2632 dontcare flag from a target that triggered update.
2634 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2636 * variable.c (initialize_file_variables): Mark pattern-specific
2637 variable as a per-target and copy export status.
2639 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2641 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2643 * implicit.c (pattern_search): When considering an implicit rule's
2644 prerequisite check that it is actually a target rather then
2645 just an entry in the file hashtable.
2647 2004-09-21 Paul D. Smith <psmith@gnu.org>
2649 * read.c (readstring): Fix some logic errors in backslash handling.
2650 (eval): Remove some unnecessary processing in buffer handling.
2651 (record_target_var): Assert that parse_variable_definition() succeeded.
2652 Reported by: Markus Mauhart <qwe123@chello.at>.
2654 * misc.c: Removed the sindex() function. All instances of this
2655 function were trivially replaceable by the standard strstr()
2656 function, and that function will always have better (or certainly
2657 no worse) performance than the very simple-minded algorithm
2658 sindex() used. This can matter with complex makefiles.
2659 * make.h: Remove the prototype for sindex().
2660 * function.c (subst_expand): Convert sindex() call to strstr().
2661 This means we no longer need to track the TLEN value so remove that.
2662 (func_findstring): Convert sindex() to strstr().
2663 * commands.c (chop_commands): Convert sindex() calls to strstr().
2664 Suggested by: Markus Mauhart <qwe123@chello.at>.
2666 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2667 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2668 If SHELL is set to CMD.EXE then assume it's batch-mode and
2669 non-unixy. I wrote the code differently from the patch, though,
2670 to make it safer. This also resolves bug #9174.
2672 2004-09-20 Paul D. Smith <psmith@gnu.org>
2674 * expand.c (variable_expand_string): Modify to invoke
2675 patsubst_expand() instead of subst_expand(); the latter didn't
2676 handle suffix patterns correctly.
2677 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2678 was used only from variable_expand_string() and is no longer used
2680 (func_subst): Ditto, on call to subst_expand().
2681 (patsubst_expand): Require the percent pointers to point to the
2682 character after the %, not to the % itself.
2683 * read.c (record_files): New call criteria for patsubst_expand().
2684 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2685 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2687 2004-09-19 Paul D. Smith <psmith@gnu.org>
2689 * function.c (subst_expand): Fix a check in by_word: look for a
2690 previous blank if we're beyond the beginning of the string, not
2691 the beginning of the word.
2692 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2694 2004-05-16 Paul D. Smith <psmith@gnu.org>
2696 * remake.c (update_goal_chain): Change the argument specifying
2697 whether we're rebuilding makefiles to be a global variable,
2698 REBUILDING_MAKEFILES.
2699 (complain): Extract the code that complains about no rules to make
2700 a target into a separate function.
2701 (update_file_1): If we tried to rebuild a file during the makefile
2702 rebuild phase and it was dontcare, then no message was printed.
2703 If we then try to build the same file during the normal build,
2704 print a message this time.
2705 (remake_file): Don't complain about un-remake-able files when
2706 we're rebuilding makefiles.
2708 2004-05-11 Paul D. Smith <psmith@gnu.org>
2710 * job.c (construct_command_argv_internal): OS/2 patches from
2711 Andreas Buening <andreas.buening@nexgo.de>.
2713 2004-05-10 Paul D. Smith <psmith@gnu.org>
2715 * remake.c (update_file): Don't walk the double-colon chain unless
2716 this is a double-colon rule. Fix suggested by Boris Kolpackov
2717 <boris@kolpackov.net>.
2719 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2720 * readme.vms: New section describing OpenVMS support and issues.
2721 * default.c (default_variables): Add support for IA64.
2722 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2723 without some privilege aborts make with the error
2724 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2725 pressing Ctrl+Y and the input device is no terminal. The change
2726 catches this error and just continues.
2728 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2730 2004-04-25 Paul D. Smith <psmith@gnu.org>
2732 * commands.c (set_file_variables): Set $< properly in the face of
2733 order-only prerequisites.
2734 Patch from Boris Kolpackov <boris@kolpackov.net>
2736 2004-04-21 Bob Byrnes <byrnes@curl.com>
2738 * main.c (main): Notice failures to remake makefiles.
2740 2004-03-28 Paul D. Smith <psmith@gnu.org>
2742 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2744 * job.c: No default shell for RISC OS.
2745 (load_too_high): Hard-code the return to 1.
2746 (construct_command_argv_internal): No sh_chars or sh_cmds.
2747 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2749 2004-03-20 Paul D. Smith <psmith@gnu.org>
2751 * variable.c (do_variable_definition): Don't append from the
2752 global set if a previous non-appending target-specific variable
2753 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2756 * expand.c (reference_variable): Don't give up on variables with
2757 no value that have the target-specific append flag set: they might
2758 have a value after all. Reported by Oliver Schmidt
2759 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2760 <nikulin@dx1cmd.inp.nsk.su>.
2762 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2763 refer to absolute pathnames in directories that don't exist: some
2764 portion of the makefile could create those directories before we
2765 match the pattern. Fixes bugs #775 and #108.
2767 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2769 * main.c (main): Free makefile_mtimes if we have any.
2770 * README.W32.template: Update documentation for the current status
2771 of the MS-Windows port.
2772 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2773 environment variable is sometimes already defined which causes the
2775 * main.c (debug_signal_handler): Only define this function if
2776 SIGUSR1 is available.
2778 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2780 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2781 * README.OS2.template: Documentation updates.
2782 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2783 link line for safety.
2784 * maintMakefile (build.sh.in): Remove an extraneous ")".
2785 * job.c (child_execute_job): Close saved FDs.
2786 * job.c (exec_command) [OS/2]: exec_command(): If the command
2787 can't be exec'ed and if the shell is not Unix-sh, then try again
2788 with argv = { "cmd", "/c", ... }. Normally, this code is never
2789 reached for the cmd shell unless the command really doesn't exist.
2790 (construct_command_argv_internal) [OS/2]: The code for cmd
2791 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2792 The CMD builtin commands are case insensitive so use strcasecmp().
2794 2004-03-19 Paul D. Smith <psmith@gnu.org>
2796 * read.c (do_define): Re-order line counter increment so the count
2797 is accurate (we were losing one line per define). Reported by
2798 Dave Yost <Dave@Yost.com>.
2800 2004-03-06 Paul D. Smith <psmith@gnu.org>
2802 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2804 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2805 * misc.c (message,error,fatal): Ditto.
2806 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2807 * config.h.W32.template: Ditto.
2808 * config.h-vms.template: Ditto.
2809 * config.ami.template: Ditto.
2811 2004-03-04 Paul D. Smith <psmith@gnu.org>
2813 * README.template: Add a note about broken /bin/sh on SunOS
2814 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2816 * misc.c (message, error, fatal): Don't use "..." if we're using
2817 varargs. ansi2knr should handle this but it doesn't work: it
2818 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2819 done. On many systems (SunOS for example) va_dcl is a #define.
2820 So, force the use of the non-"..." version on pre-ANSI compilers.
2822 * maintMakefile (sign-dist): Create some rules to help automate
2823 the new GNU ftp upload method.
2825 2004-02-24 Paul D. Smith <psmith@gnu.org>
2827 * config.h.W32.template: Add HAVE_STDARG_H
2828 * config.h-vms.template: Ditto.
2829 * config.ami.template: Ditto.
2831 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2833 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2834 * build_w32.bat: Remove extra "+".
2836 2004-02-23 Paul D. Smith <psmith@gnu.org>
2838 * make.h: Create an UNUSED macro to mark unused parameters.
2839 * (many): Clean up warnings by applying UNUSED, fixing
2840 signed/unsigned incompatibilities, etc.
2842 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2844 * filedef.h: Name the command_state enumeration.
2845 * file.c (set_command_state): Use the enumeration in the function
2848 * configure.in: Explicitly set SET_MAKE to empty, to disable
2849 MAKE=make even when no make already exists. Fix bug #3823.
2851 2004-02-22 Paul D. Smith <psmith@gnu.org>
2853 * maintMakefile: Perl script to clean up all non-CVS files. Use
2854 it on all the subdirectories for the cvs-clean target.
2856 * main.c (decode_switches): Require non-empty strings for all our
2857 string command-line options. Fixes Debian bug # 164165.
2859 * configure.in: Check for stdarg.h and varargs.h.
2860 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2861 for printing messages.
2862 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2867 A number of patches for OS/2 support from Andreas Buening
2868 <andreas.buening@nexgo.de>:
2870 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2871 disable the SIGCHLD handler.
2872 (reap_children) [OS/2]: Remove special handling of job_rfd.
2873 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2874 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2875 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2876 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2877 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2880 2004-02-21 Paul D. Smith <psmith@gnu.org>
2882 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2883 <mail@kristov.de> reports that if process_begin() fails we don't
2884 handle the error condition correctly in all cases.
2885 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2886 to have a newline on the message.
2888 * job.c (construct_command_argv_internal): Add "test" to UNIX
2889 sh_cmds[]. Fixes Savannah bug # 7606.
2891 2004-02-04 Paul D. Smith <psmith@gnu.org>
2893 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2894 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2895 Hartmut Becker <Hartmut.Becker@hp.com>.
2897 2004-01-21 Paul D. Smith <psmith@gnu.org>
2899 * job.c (load_too_high): Implement an algorithm to control the
2900 "thundering herd" problem when using -l to control job creation
2901 via the load average. The system only recomputes the load once a
2902 second but we can start many jobs in a second. To solve this we
2903 keep track of the number of jobs started in the last second and
2904 apply a weight to try to guess what a correct load would be.
2905 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2906 Also fixes bug #4693.
2907 (reap_children): Decrease the job count for this second.
2908 (start_job_command): Increase the job count for this second.
2910 * read.c (conditional_line): Expand the text after ifn?def before
2911 checking to see if it's a single word. Fixes bug #7257.
2913 2004-01-09 Paul D. Smith <psmith@gnu.org>
2915 * file.c (print_file): Recurse to print all targets in
2916 double-colon rules. Fixes bug #4518, reported (with patch) by
2917 Andrew Chatham <chatham@google.com>.
2919 2004-01-07 Paul D. Smith <psmith@gnu.org>
2921 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2922 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2923 AC_FUNC_SETVBUF_REVERSED.
2925 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2926 (MAKE Variable): Fix Savannah bug #4898.
2928 * job.c (construct_command_argv_internal): Add "!" to the list of
2929 shell escape chars. POSIX sh allows it to appear before a
2930 command, to negate the exit code. Fixes bug #6404.
2932 * implicit.c (pattern_search): When matching an implicit rule,
2933 remember which dependencies have the ignore_mtime flag set.
2934 Original fix provided in Savannah patch #2349, by Benoit
2935 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2937 2003-11-22 Paul D. Smith <psmith@gnu.org>
2939 * README.W32.template (Outputs): Clarification on -j with
2940 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2943 2003-11-02 Paul D. Smith <psmith@gnu.org>
2945 * function.c (func_if): Strip all the trailing whitespace from the
2946 condition, then don't expand it. Fixed bug # 5798.
2948 * expand.c (recursively_expand_for_file): If we're expanding a
2949 variable with no file context, then use the variable's context.
2952 2003-10-21 Paul D. Smith <psmith@gnu.org>
2954 * main.c (log_working_directory): Add newlines to printf()s.
2956 * README.cvs: Add a note to ignore warnings during autoreconf.
2958 * maintMakefile (po_repo): Set a new URL for PO file updates.
2959 (get-config/config.guess get-config/config.sub): Get these files
2960 from the Savannah config project instead of ftp.gnu.org.
2962 2003-10-05 Paul Eggert <eggert@twinsun.com>
2964 * main.c (main): Avoid potential subscript error if environ has
2967 2003-08-22 Paul D. Smith <psmith@gnu.org>
2969 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2970 systems which don't yet implement the C89 standard :-/.
2972 2003-07-18 Paul D. Smith <psmith@gnu.org>
2974 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2975 [WINDOWS32]: Initialize hash.
2977 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2979 * dir.c (read_dirstream): Provide a workaround for broken versions of
2980 the MinGW dirent structure.
2982 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2984 * w32/include/dirent.h: Add __MINGW32__ filter.
2986 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2988 * make.h: Add global declaration of *make_host.
2989 * main.c (print_usage): Remove local declaration of *make_host.
2990 (print_version): Display "This program built for ..." after Copyright
2993 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2995 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2996 execution of "makeinfo --html make.texi".
2998 2003-04-30 Paul D. Smith <psmith@gnu.org>
3000 * build.template: Make some changes to maybe allow this script to
3001 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3003 * README.OS2.template: New file for OS/2 support. Original
3004 contributed by Andreas Buening.
3005 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3008 2003-04-19 Paul D. Smith <psmith@gnu.org>
3010 Fix bug #1405: allow a target to match multiple pattern-specific
3013 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3014 variable.c, where they've always belonged.
3015 * rule.h: Move the prototypes and struct pattern_var as well.
3016 * variable.c (initialize_file_variables): Invoke
3017 lookup_pattern_var() in a loop, until no more matches are found.
3018 If a match is found, create a new variable set for the target's
3019 pattern variables. Then merge the contents of each matching
3020 pattern variable set into the target's pattern variable set.
3021 (lookup_pattern_var): Change this function to be usable
3022 in a loop. It takes a starting position: if NULL, start at the
3023 beginning; if non-NULL, start with the pattern variable after that
3024 position, and return the next matching pattern.
3025 (create_pattern_var): Create a unique instance of
3026 pattern-specific variables for every definition in the makefile.
3027 Don't combine the same pattern together. This allows us to
3028 process the variable handling properly even when the same pattern
3029 is used multiple times.
3030 (parse_variable_definition): New function: break out the parsing
3031 of a variable definition line from try_variable_definition.
3032 (try_variable_definition): Call parse_variable_definition to
3034 (print_variable_data_base): Print out pattern-specific variables.
3035 * variable.h (struct variable): Remember when a variable is
3036 conditional. Also remember its flavor.
3037 (struct pattern_var): Instead of keeping a variable set, we just
3038 keep a single variable for each pattern.
3039 * read.c (record_target_var): Each pattern variable contains only a
3040 single variable, not a set, so create it properly.
3041 * doc/make.texi (Pattern-specific): Document the new behavior.
3043 2003-04-17 Paul D. Smith <psmith@gnu.org>
3045 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3046 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3047 file/directory naming rules for VMS so I can't tell whether this
3050 2003-04-09 Paul D. Smith <psmith@gnu.org>
3052 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3053 DOS-style pathnames: backslash separators and drive specifiers.
3055 2003-03-28 Paul D. Smith <psmith@gnu.org>
3057 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3058 the intermediate flag on all targets. Fixes bug #2515.
3060 2003-03-24 Paul D. Smith <psmith@gnu.org>
3062 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3063 Upgrade to autoconf 2.57 and automake 1.7.3.
3065 * job.c: More OS/2 changes from Andreas Buening.
3067 * file.c (print_file): Fix variable initialization.
3070 * remake.c (notice_finished_file):
3072 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3073 some calls (like readdir()) return NULL in valid situations
3074 without resetting errno. Fixes bug #2846.
3076 2003-02-25 Paul D. Smith <psmith@gnu.org>
3078 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3080 * job.c (_is_unixy_shell) [OS/2]: New function.
3081 Set default shell to /bin/sh.
3082 (reap_children): Close the job_rfd pipe here since we don't use a
3084 (set_child_handler_action_flags): define this to empty on OS/2.
3085 (start_job_command): Close the jobserver pipe and use
3086 child_execute_job() instead of fork/exec.
3087 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3088 rather than exec'ing, then reconfigure stdin/stdout.
3089 (exec_command): Rewrite to use spawn instead of exec. Return the
3092 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3093 in DOS. Handle the TEMP environment variable as in DOS. Don't
3094 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3095 use -j in DOS mode. Use child_execute_job() instead of
3098 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3101 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3102 prototypes that return values.
3104 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3106 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3107 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3109 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3112 2003-02-24 Paul D. Smith <psmith@gnu.org>
3114 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3115 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3116 (child_execute_job) [VMS]: Handle error status properly.
3117 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3119 * function.c (func_shell): Use EINTRLOOP() while reading from the
3120 subshell pipe (Fixes bug #2502).
3121 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3123 * main.c (main): Ditto.
3125 2003-01-30 Paul D. Smith <psmith@gnu.org>
3127 * read.c (eval): eval() was not fully reentrant, because the
3128 collapsed buffer was static. Change it to be an automatic
3129 variable so that eval() can be invoked recursively.
3131 (eval): Apply patch # 1022: fix memory reference error on long
3132 target-specific variable lines.
3133 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3135 * function.c (check_numeric): Combine the is_numeric() function
3136 into this function, since it's only called from one place.
3137 Constify this function. Have it print the incorrect string in the
3138 error message. Fixes bug #2407.
3139 (strip_whitespace): Constify.
3140 (func_if): Constify.
3141 * expand.c (expand_argument): Constify.
3143 2003-01-29 Paul D. Smith <psmith@gnu.org>
3145 Fix bug # 2169, also reported by other people on various systems.
3147 * make.h: Some systems, such as Solaris and PTX, do not fully
3148 implement POSIX-compliant SA_RESTART functionality; important
3149 system calls like stat() and readdir() can still fail with EINTR
3150 even if SA_RESTART has been set on the signal handler. So,
3151 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3152 EINTR for system calls which return -1 or 0 (NULL), respectively,
3154 Also, remove the old atomic_stat()/atomic_readdir() and
3155 HAVE_BROKEN_RESTART handling.
3157 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3159 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3160 * remake.c (touch_file): Ditto.
3162 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3163 * read.c (construct_include_path): Ditto.
3164 * remake.c (name_mtime): Ditto.
3165 * vpath.c (selective_vpath_search): Ditto.
3166 * dir.c (find_directory): Ditto.
3167 (local_stat): Ditto.
3168 (find_directory): Use ENULLLOOP() to wrap opendir().
3169 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3171 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3172 atomic_readdir() handling.
3174 2003-01-22 Paul D. Smith <psmith@gnu.org>
3176 * function.c (func_call): Fix Bug #1744. If we're inside a
3177 recursive invocation of $(call ...), mask any of the outer
3178 invocation's arguments that aren't used by this one, so that this
3179 invocation doesn't "inherit" them accidentally.
3181 2002-12-05 Paul D. Smith <psmith@gnu.org>
3183 * function.c (subst_expand): Valery Khamenia reported a
3184 pathological performance hit when doing substitutions on very
3185 large values with lots of words: turns out we were invoking
3186 strlen() a ridiculous number of times. Instead of having each
3187 call to sindex() call strlen() again, keep track of how much of
3188 the text we've seen and pass the length to sindex().
3190 2002-11-19 Paul D. Smith <psmith@gnu.org>
3192 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3195 2002-11-16 Paul D. Smith <psmith@gnu.org>
3197 * NMakefile.template (OBJS): Add hash.c object file.
3198 * SMakefile.template (srcs): Ditto.
3199 * Makefile.ami (objs): Ditto.
3200 * build_w32.bat: Ditto.
3202 * Makefile.DOS.template: Remove extra dependencies.
3204 2002-10-25 Paul D. Smith <psmith@gnu.org>
3206 * expand.c (install_variable_buffer): New function. Install a new
3207 variable_buffer context and return the previous one.
3208 (restore_variable_buffer): New function. Free the current
3209 variable_buffer context and put a previously saved one back.
3210 * variable.h: Prototypes for {install,restore}_variable_buffer.
3211 * function.c (func_eval): Push a new variable_buffer context
3212 before we eval, then restore the old one when we're done.
3215 * read.c (install_conditionals): New function. Install a new
3216 conditional context and return the previous one.
3217 (restore_conditionals): New function. Free the current
3218 conditional context and put a previously saved one back.
3219 (eval): Use the {install,restore}_conditionals for "include"
3221 (eval_buffer): Use {install,restore}_conditionals to preserve the
3222 present conditional state before we evaluate the buffer.
3225 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3227 (Recursion): Add a variable index entry for CURDIR.
3229 * README.cvs: Update to appropriate versions.
3230 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3231 don't need to copy loadavg.c: automake is smart enough to create
3232 it for me. Still have a bug in automake related to ansi2knr tho.
3234 2002-10-14 Paul D. Smith <psmith@gnu.org>
3236 * remake.c (notice_finished_file): Only touch targets if they have
3237 at least one command (as per POSIX). Resolve Bug #1418.
3239 * *.c: Convert to using ANSI C-style function definitions.
3240 * Makefile.am: Enable the ansi2knr feature of automake.
3241 * configure.in: ditto.
3243 2002-10-13 Paul D. Smith <psmith@gnu.org>
3245 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3246 for automatic variable values like $^, etc. In the case of very
3247 large lists of prerequisites this causes problems. Instead reuse
3248 a static buffer (resizeable) for each variable.
3250 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3251 target-specific variable definitions. Check for it and set an
3253 (record_target_var): Set the export field to v_export if the
3254 "exported" flag is set.
3255 * doc/make.texi (Target-specific): Document the ability to use
3258 * doc/make.texi: Change the name of the section on automatic
3259 variables from "Automatic" to "Automatic Variables". Added text
3260 clarifying the scope of automatic variables.
3262 2002-10-04 Paul D. Smith <psmith@gnu.org>
3264 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3266 (record_files): Ditto.
3268 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3269 the search for the '=' to only within the enclosing parens.
3271 2002-10-03 Paul D. Smith <psmith@gnu.org>
3273 Version 3.80 released.
3275 * dir.c: Change hash functions to use K&R function definition style.
3276 * function.c: Ditto.
3278 * variable.c: Ditto.
3280 Update to automake 1.7.
3282 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3283 (pdf): Remove this target as automake now provides one.
3285 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3287 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3289 * makefile.com: Updates for GNU make 3.80.
3290 * makefile.vms: Ditto.
3292 2002-09-23 Paul D. Smith <psmith@gnu.org>
3294 * read.c (enum make_word_type): Remove w_comment.
3295 (get_next_mword): Don't treat comment characters as special; where
3296 this function is used we will never see a comment (it's stripped
3297 before we get here) and treating comments specially means that
3298 targets like "foo\#bar" aren't handled properly.
3300 2002-09-18 Paul D. Smith <psmith@gnu.org>
3302 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3304 * read.c (eval): Expansion of arguments to export/unexport was
3305 ignoring all arguments after the first one. Change the algorithm
3306 to expand the whole line once, then parse the results.
3308 2002-09-17 Paul D. Smith <psmith@gnu.org>
3310 Fix Bug #940 (plus another bug I found while looking at this):
3312 * read.c (record_target_var): enter_file() will add a new entry if
3313 it's a double-colon target: we don't want to do that in this
3314 situation. Invoke lookup_file() and only enter_file() if it does
3315 not already exist. If the file we get back is a double-colon then
3316 add this variable to the "root" double-colon target.
3318 * variable.c (initialize_file_variables): If this file is a
3319 double-colon target but is not the "root" target, then initialize
3320 the root and make the root's variable list the parent of our
3323 2002-09-13 Paul D. Smith <psmith@gnu.org>
3325 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3327 * hash.c (round_up_2): Get rid of a warning.
3329 2002-09-12 Paul D. Smith <psmith@gnu.org>
3331 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3332 so it doesn't complain about getloadavg.c.
3334 * commands.c (set_file_variables): Make sure we always alloca() at
3335 least 1 character for the value of $? (for '\0').
3337 2002-09-11 Paul D. Smith <psmith@gnu.org>
3339 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3340 macro to use RESULT instead of the incorrect _RESULT_.
3342 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3343 and atomic_readdir(). We need to #include dirent.h to get this to
3345 * misc.c (atomic_readdir): Fix typos.
3347 2002-09-10 Paul D. Smith <psmith@gnu.org>
3349 * read.c (eval): Expand variable lists given to export and
3350 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3351 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3353 * doc/make.texi (Variables/Recursion): Document this.
3354 (Conditional Syntax): And here.
3356 2002-09-09 Paul D. Smith <psmith@gnu.org>
3358 * configure.in: Check for memmove().
3360 2002-09-07 Paul D. Smith <psmith@gnu.org>
3362 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3363 Michael Sterrett <msterret@coat.com> reports that while it has
3364 SA_RESTART, it does not work properly.
3366 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3367 that invokes stat() and loops to do it again if it returns EINTR.
3368 (atomic_readdir): Ditto, with readdir().
3370 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3371 and readdir() to atomic_stat() and atomic_readdir().
3373 2002-09-04 Paul D. Smith <psmith@gnu.org>
3375 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3376 reports that GNU make sometimes doesn't recognize that targets can
3377 be made, when directories can be created as prerequisites. He
3378 reports that changing the order of predicates in the DEP->changed
3379 flag test so that lookup_file() is always performed, solves this
3382 2002-08-08 Paul D. Smith <psmith@gnu.org>
3384 * configure.in: Require a newer version of gettext.
3386 * misc.c (perror_with_name): Translate the format string (for
3387 right-to-left language support).
3388 (pfatal_with_name): Ditto.
3390 * main.c: Create a static array of strings to store the usage
3391 text. This is done to facilitate translations.
3392 (struct command_switch): Remove argdesc and description fields.
3393 (switches): Remove values for obsolete fields.
3394 (print_usage): Print each element of the usage array.
3396 * hash.c: Change function definitions to be K&R style.
3398 2002-08-02 Paul D. Smith <psmith@gnu.org>
3400 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3401 this one because it's too hard to get right. We'll look at it for
3403 * main.c (main): Don't create the .TARGETS variable.
3404 * variable.c (handle_special_var): Don't handle .TARGETS.
3406 2002-08-01 Paul D. Smith <psmith@gnu.org>
3408 * main.c (switches): Add a new option, -B (--always-make). If
3409 specified, make will rebuild all targets that it encounters even
3410 if they don't appear to be out of date.
3411 (always_make_flag): New flag.
3412 * make.h: Extern always_make_flag.
3413 * remake.c (update_file_1): Check always_make_flag; if it's set we
3414 will always rebuild any target we can, even if none of its
3415 prerequisites are newer.
3418 * doc/make.texi (Shell Function): Make it clear that make
3419 variables marked as "export" are not passed to instances of the
3422 Add new introspection variable .VARIABLES and .TARGETS.
3424 * variable.c (handle_special_var): New function. If the variable
3425 reference passed in is "special" (.VARIABLES or .TARGETS),
3426 calculate the new value if necessary. .VARIABLES is handled here:
3427 walk through the hash of defined variables and construct a value
3428 which is a list of the names. .TARGETS is handled by
3429 build_target_list().
3430 (lookup_variable): Invoke handle_special_var().
3431 * file.c (build_target_list): Walk through the hask of known files
3432 and construct a list of the names of all the ones marked as
3434 * main.c (main): Initialize them to empty (and as simple variables).
3435 * doc/make.texi (Special Variables): Document them.
3436 * NEWS: Mention them.
3438 * variable.h (struct variable): Add a new flag "exportable" which
3439 is true if the variable name is valid for export.
3440 * variable.c (define_variable_in_set): Set "exportable" when a new
3441 variable is defined.
3442 (target_environment): Use the "exportable" flag instead of
3443 re-checking the name here... an efficiency improvement.
3445 2002-07-31 Paul D. Smith <psmith@gnu.org>
3447 * config.h-vms.template: Updates to build on VMS. Thanks to
3448 Brian_Benning@aksteel.com for helping verify the build.
3449 * makefile.com: Build the new hash.c file.
3450 * hash.h: Use strcpmi(), not stricmp(), in the
3451 HAVE_CASE_INSENSITIVE_FS case.
3453 2002-07-30 Paul D. Smith <psmith@gnu.org>
3455 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3456 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3457 Reported by <Brian_Benning@aksteel.com>.
3459 2002-07-10 Paul D. Smith <psmith@gnu.org>
3461 * variable.c (pop_variable_scope): Remove variable made unused by
3462 new hash infrastructure.
3463 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3464 comparisons as well as name comparisons.
3465 * variable.h: Add a prototype for new hash_init_function_table().
3466 * file.c (lookup_file): Remove variables made unused by new hash
3468 * dir.c (directory_contents_hash_2): Missing return of hash value.
3469 (dir_contents_file_exists_p): Remove variables made unused by new
3470 hash infrastructure.
3473 Installed Greg McGary's integration of the hash functions from the
3474 GNU id-utils package:
3476 2002-07-10 Greg McGary <greg@mcgary.org>
3478 * scripts/functions/filter-out: Add literals to to the
3479 pattern space in order to add complexity, and trigger
3480 use of an internal hash table. Fix documentation strings.
3481 * scripts/targets/INTERMEDIATE: Reverse order of files
3482 passed to expected `rm' command.
3484 2002-07-10 Greg McGary <greg@mcgary.org>

3576 2002-07-10 Paul D. Smith <psmith@gnu.org>
3578 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3579 prerequisite list. A real SysV make will expand the entire
3580 prerequisites list _twice_: we don't do that as it's a big
3581 backward-compatibility problem. We only replace those specific
3584 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3585 references left in the list of prerequisites. Check for .POSIX as
3586 we record targets, so we can disable non-POSIX behavior while
3587 reading makefiles as well as running them.
3588 (eval): Check the prerequisite list to see if we have anything
3589 that looks like a SysV prerequisite variable reference.
3591 2002-07-09 Paul D. Smith <psmith@gnu.org>
3593 * doc/make.texi (Prerequisite Types): Add a new section describing
3594 order-only prerequisites.
3596 * read.c (uniquize_deps): If we have the same file as both a
3597 normal and order-only prereq, get rid of the order-only prereq,
3598 since the normal one supersedes it.
3600 2002-07-08 Paul D. Smith <psmith@gnu.org>
3602 * AUTHORS: Added Greg McGary to the AUTHORS file.
3603 * NEWS: Blurbed order-only prerequisites.
3604 * file.c (print_file): Show order-only deps properly when printing
3607 * maintMakefile: Add "update" targets for wget'ing the latest
3608 versions of various external files. Taken from Makefile.maint in
3611 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3612 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3614 2002-07-07 Paul D. Smith <psmith@gnu.org>
3616 * po/*.po: Remove. We'll use wget to retrieve them at release
3619 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3620 rather than a shell you get an exception. Make sure we look up
3621 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3623 * remake.c (notice_finished_file): Fix handling of -t flag.
3624 Patch provided by Henning Makholm <henning@makholm.net>.
3626 * implicit.c (pattern_search): Some systems apparently run short
3627 of stack space, and using alloca() in this function caused an
3628 overrun. I modified it to use xmalloc() on the two variables
3629 which seemed like they might get large. Fixes Bug #476.
3631 * main.c (print_version): Update copyright notice to conform with
3633 (print_usage): Update help output.
3635 * function.c (func_eval): Create a new make function, $(eval
3636 ...). Expand the arguments, put them into a buffer, then invoke
3637 eval_buffer() on the resulting string.
3638 (func_quote): Create a new function, $(quote VARNAME). Inserts
3639 the value of the variable VARNAME without expanding it any
3642 * read.c (struct ebuffer): Change the linebuffer structure to an
3643 "eval buffer", which can be either a file or a buffer.
3644 (eval_makefile): Move the code in the old read_makefile() which
3645 located a makefile into here: create a struct ebuffer with that
3646 information. Have it invoke the new function eval() with that
3648 (eval_buffer): Create a new function that creates a struct ebuffer
3649 that holds a string buffer instead of a file. Have it invoke
3650 eval() with that ebuffer.
3651 (eval): New function that contains the guts of the old
3652 read_makefile() function: this function parses makefiles. Obtains
3653 data to parse from the provided ebuffer. Some modifications to
3654 make the flow of the function cleaner and clearer. Still could
3655 use some work here...
3656 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3657 contents of the define/endef variable from the ebuffer.
3658 (readstring): Read the next line from a string-style ebuffer.
3659 (readline): Read the next line from an ebuffer. If it's a string
3660 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3663 * dep.h (eval_buffer): Prototype eval_buffer();
3665 * variable.c (do_variable_definition): Make sure that all
3666 non-target-specific variables are registered in the global set.
3667 If we're invoked from an $(eval ...) we might be inside a $(call
3668 ...) or other function which has pushed a variable scope; we still
3669 want to define our variables from evaluated makefile code in the
3672 2002-07-03 Greg McGary <greg@mcgary.org>
3674 * dep.h (struct dep) [ignore_mtime]: New member.
3675 [changed]: convert to a bitfield.
3676 * implicit.c (pattern_search): Zero ignore_mtime.
3677 * main.c (main, handle_non_switch_argument): Likewise.
3678 * rule.c (convert_suffix_rule): Likewise.
3679 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3680 (read_makefile): Parse '|' in prerequisite list.
3681 (uniquize_deps): Consider ignore_mtime when comparing deps.
3682 * remake.c (update_file_1, check_dep): Don't force remake for
3683 dependencies that have d->ignore_mtime.
3684 * commands.c (FILE_LIST_SEPARATOR): New constant.
3685 (set_file_variables): Don't include a
3686 prerequisite in $+, $^ or $? if d->ignore_mtime.
3689 2002-06-18 Paul D. Smith <psmith@gnu.org>
3691 * make.texinfo: Updates for next revision. New date/rev/etc.
3692 Recreate all Info menus. Change license on the manual to the GNU
3693 Free Documentation License. A number of typos.
3694 (Variables Simplify): Don't use "-" before it's defined.
3695 (Automatic Prerequisites): Rewrite the target example to work
3696 properly if the compile fails. Remove incorrect comments about
3697 how "set -e" behaves.
3698 (Text Functions): Move the "word", "wordlist", "words", and
3699 "firstword" functions here, from "File Name Functions".
3700 * make-stds.texi: Update from latest GNU version.
3701 * fdl.texi: (created) Import the latest GNU version.
3703 2002-06-06 Paul D. Smith <psmith@gnu.org>
3705 * variable.c (do_variable_definition): New function: extract the
3706 part of try_variable_definition() that actually sets the value
3707 into a separate function.
3708 (try_variable_definition): Call do_variable_definition() after
3709 parsing the variable definition string.
3710 (define_variable_in_set): Make the name argument const.
3712 * variable.h (enum variable_flavor): Make public.
3713 (do_variable_definition): Create prototype.
3715 * read.c (read_all_makefiles): Create a new built-in variable,
3717 (read_makefile): Add each makefile read in to this variable value.
3719 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3721 * Makefile.DOS.template: Tweak according to changes in the
3722 distribution. Add back the dependencies of *.o files.
3724 * configh.dos.template: Synchronize with config.h.in.
3726 2002-05-09 Paul D. Smith <psmith@gnu.org>
3728 * file.c (file_timestamp_now): Use K&R function declaration.
3730 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3731 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3732 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3733 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3734 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3735 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3736 nlist.n_name is a pointer rather than an array.
3738 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3739 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3740 * configure.in: Use it instead of the old version.
3742 * main.c (main): Prefer setvbuf() to setlinebuf().
3744 2002-05-08 Paul D. Smith <psmith@gnu.org>
3746 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3747 (loadavg_LDADD): Ditto.
3749 2002-04-29 Paul D. Smith <psmith@gnu.org>
3751 * expand.c (recursively_expand_for_file): Rename
3752 recursively_expand() to recursively_expand_for_file() and provide
3753 an extra argument, struct file. If the argument is provided, set
3754 the variable scope to that of the file before expanding.
3755 * variable.h (recursively_expand): Make this a macro that invokes
3756 recursively_expand_for_file() with a NULL file pointer.
3757 * variable.c (target_environment): Call the renamed function and
3758 provide the current file context.
3759 Fixes Debian bug #144306.
3761 2002-04-28 Paul D. Smith <psmith@gnu.org>
3763 Allow $(call ...) user-defined variables to be self-referencing
3764 without throwing an error. Allows implementation of transitive
3765 closures, among other possibly useful things.
3766 Requested by: Philip Guenther <guenther@sendmail.com>
3768 * variable.h (struct variable): Add a new field: exp_count, and
3769 new macros to hold its size and maximum value.
3770 (warn_undefined): Make this a macro.
3771 * variable.c (define_variable_in_set): Initialize it.
3772 * expand.c (recursively_expand): If we detect recursive expansion
3773 of a variable, check the exp_count field. If it's greater than 0
3774 allow the recursion and decrement the count.
3775 (warn_undefined): Remove this (now a macro in variable.h).
3776 * function.c (func_call): Before we expand the user-defined
3777 function, modify its exp_count field to contain the maximum
3778 number of recursive calls we'll allow. After the call, reset it
3781 2002-04-21 Paul D. Smith <psmith@gnu.org>
3783 Modified to use latest autoconf (2.53), automake (1.6.1), and
3784 gettext (0.11.1). We're using gettext's new "external" support,
3785 to avoid including libintl source with GNU make.
3787 * README.cvs: New file. Explain how to build GNU make from CVS.
3789 * configure.in: Modify checking for the system glob library.
3790 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3791 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3792 etc. will manage it correctly). Set an automake conditional
3793 USE_LOCAL_GLOB to decide whether to compile the glob library.
3795 * getloadavg.c (main): Include make.h in the "TEST" program to
3798 * Makefile.am: Remove special rules for loadavg. Replace them
3799 with Automake capabilities for building extra programs.
3801 * signame.c: This file does nothing if the system provide
3802 strsignal(). If not, it implements strsignal(). If the system
3803 doesn't define sys_siglist, then we make our own; otherwise we use
3805 * signame.h: Removed.
3807 * main.c (main): No need to invoke signame_init(). Update copyright.
3809 * ABOUT-NLS: Removed.
3810 * gettext.c: Removed.
3811 * gettext.h: Get a simplified copy from the gettext package.
3813 * i18n/*.po: Moved to po/.
3816 * config/*: Created. Contains package configuration helper files.
3817 * config.guess, config.sub: Moved to config directory.
3819 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3820 Rework to use new-style autoconf features. Use the "external"
3821 mode for gettext. Make the build.sh config file conditional on
3822 whether build.sh.in exists, to avoid autoconf errors.
3823 * acinclude.m4: Removed almost all macros as being obsolete.
3824 Rewrote remaining macros to use AC_DEFINE.
3825 * acconfig.h: Removed.
3827 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3828 conditional to handle customs support. Remove special handling
3831 2002-04-20 Paul D. Smith <psmith@gnu.org>
3833 * function.c (func_call): Don't mark the argument variables $1,
3834 etc. as recursive. They've already been fully expanded so
3835 there's no need to do it again, and doing so strips escaped $'s.
3836 Reported by Sebastian Glita <glseba@yahoo.com>.
3838 * remake.c (notice_finished_file): Walk through double-colon
3839 entries via the prev field, not the next field!
3840 Reported by Greg McGary <greg@mcgary.org>.
3842 * main.c (main): If the user specifies -q and asks for a specific
3843 target which is a makefile, we got an assert. In that case it
3844 turns out we should continue normally instead.
3846 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3848 * i18n/he.po: Installed a new translation.
3850 2002-01-07 Paul D. Smith <psmith@gnu.org>
3852 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3854 2001-12-04 Paul D. Smith <psmith@gnu.org>
3856 * i18n/ja.po: Installed an updated translation.
3858 2001-09-06 Paul Eggert <eggert@twinsun.com>
3860 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3861 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3863 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3865 (main): Get rid of any avoidable limit on stack size.
3867 2001-09-04 Paul D. Smith <psmith@gnu.org>
3869 * i18n/da.po: Installed an updated translation.
3871 2001-08-03 Paul D. Smith <psmith@gnu.org>
3873 * i18n/fr.po: Installed an updated translation.
3874 Resolves Debian bug #106720.
3876 2001-06-13 Paul D. Smith <psmith@gnu.org>
3878 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3881 2001-06-11 Paul D. Smith <psmith@gnu.org>
3883 * i18n/ko.po: Installed a new translation.
3885 2001-05-06 Paul D. Smith <psmith@gnu.org>
3887 Modify the EINTR handling.
3889 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3890 the way in which we manage the file descriptor/signal handler race
3891 trap to be more efficient.
3893 2001-05-06 Paul Eggert <eggert@twinsun.com>
3895 Restart almost all system calls that are interrupted, instead
3896 of worrying about EINTR. The lone exception is the read() for
3899 * configure.in (HAVE_SA_RESTART): New macro.
3900 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3901 * main.c (main): Use SA_RESTART instead of the old,
3902 nonstandard SA_INTERRUPT.
3904 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3905 * main.c (bsd_signal): New function or macro,
3906 if the implementation doesn't supply it.
3907 (The bsd_signal function will be in POSIX 1003.1-200x.)
3908 (HANDLESIG): Remove.
3909 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3911 * make.h (EINTR_SET): Remove.
3912 (SA_RESTART): New macro.
3914 * arscan.c (ar_member_touch): Don't worry about EINTR.
3915 * function.c (func_shell): Likewise.
3916 * job.c (reap_children, free_child, new_job): Likewise.
3917 * main.c (main): Likewise.
3918 * remake.c (touch_file, name_mtime): Likewise.
3920 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3921 if fstat failed with errno!=EINTR, the error was ignored.
3923 * job.c (set_child_handler_action_flags): New function.
3924 (new_job): Use it to temporarily clear the SIGCHLD action flags
3925 while reading the token.
3927 2001-05-02 Paul D. Smith <psmith@gnu.org>
3929 * job.c (start_job_command): Don't add define/endef per-line flags
3930 to the top-level flags setting.
3932 2001-04-03 Paul D. Smith <psmith@gnu.org>
3934 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3935 bit on error, so check for odd return values, not non-0 return
3937 (VMS_get_member_info): Calculate the timezone differences correctly.
3938 Reported by John Fowler <jfowler@nyx.net>.
3941 2001-03-14 Paul D. Smith <psmith@gnu.org>
3943 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3944 value before invoking define_variable().
3945 Reported by John Fowler <jfowler@nyx.net>.
3947 2001-02-07 Paul D. Smith <psmith@gnu.org>
3949 * read.c (record_target_var): If we reset the variable due to a
3950 command-line variable setting overriding it, turn off the "append"
3953 2001-01-17 Paul D. Smith <psmith@gnu.org>
3955 * variable.c (lookup_variable) [VMS]: When getting values from the
3956 environment, allocate enough space for the _value_ plus escapes,
3957 not enough space for the name plus escapes :-/.
3958 Reported by John Fowler <jfowler@nyx.net>.
3960 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3961 warnings that make generates, so it doesn't look like an error.
3962 Reported by Karl Berry <karl@gnu.org>.
3965 Fix for PR/2020: Rework appended target-specific variables. I'm
3966 fairly confident this algorithm is finally correct.
3968 * expand.c (allocated_variable_append): Rewrite. Instead of
3969 expanding each appended variable then adding all the expanded
3970 strings together, we append all the unexpanded values going up
3971 through the variable set contexts, then expand the final result.
3972 This behaves just like non-target-specific appended variable
3973 values, while the old way didn't in various corner cases.
3974 (variable_append): New function: recursively append the unexpanded
3975 value of a variable, walking from the outermost variable scope to
3977 * variable.c (lookup_variable): Remove the code that looked up the
3978 variable set list if the found variable was "append". We don't
3980 (lookup_variable_in_set): Make this non-static so we can use it
3982 (try_variable_definition): Use lookup_variable_in_set() rather
3983 than faking out current_variable_set_list by hand (cleanup).
3984 * variable.h: Add a prototype for the now non-static
3985 lookup_variable_in_set().
3987 2000-11-17 Paul D. Smith <psmith@gnu.org>
3989 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3990 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3991 before throwing a fit.
3993 2000-11-17 Paul D. Smith <psmith@gnu.org>
3995 * read.c (readline): CRLF calculations had a hole, if you hit the
3996 buffer grow scenario just right. Reworked the algorithm to avoid
3997 the need for len or lastlen at all. Problem description with
3998 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4000 2000-10-24 Paul D. Smith <psmith@gnu.org>
4002 * gettext.c (SWAP): Declare this with the prototype, otherwise
4003 some systems don't work (non-32-bit? Reported for Cray T3E).
4004 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4006 2000-10-05 Paul D. Smith <psmith@gnu.org>
4008 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4009 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4011 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4013 2000-09-22 Paul D. Smith <psmith@gnu.org>
4015 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4016 parts of the real gettext.h here, and we expect to really include
4017 the real gettext.h later. If we keep this #define, it's ignored.
4019 2000-09-21 Paul D. Smith <psmith@gnu.org>
4021 * main.c (log_working_directory): Rework the text to use complete
4022 sentences, to make life simpler for the translators.
4024 2000-08-29 Paul D. Smith <psmith@gnu.org>
4026 * file.c (remove_intermediates): Print a debug message before we
4027 remove intermediate files, so the user (if she uses -d) knows
4030 2000-08-21 Paul D. Smith <psmith@gnu.org>
4032 * variable.c (try_variable_definition): Change how we handle
4033 target-specific append variable defns: instead of just setting the
4034 value, expand it as an append _but_ only within the current
4035 target's context. Otherwise we lose all but the last value if the
4036 variable is appended more than once within the current target
4037 context. Fixes PR/1831.
4039 2000-08-16 Paul D. Smith <psmith@gnu.org>
4041 * function.c (func_shell): Nul-terminate the buffer before
4042 printing an exec error message (just in case it's not!).
4043 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4045 2000-07-25 Paul D. Smith <psmith@gnu.org>
4047 * job.c (construct_command_argv_internal): Add "~" to the list of
4048 sh_chars[] which disallow optimizing out the shell call.
4050 2000-07-23 Paul Eggert <eggert@twinsun.com>
4052 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4053 supersedes --disable-nsec-timestamps.
4054 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4055 * README: Remove --disable-nsec-timestamps.
4057 * filedef.h (struct file.low_resolution_time): New member.
4058 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4059 * remake.c (update_file_1):
4060 Avoid spurious rebuilds due to low resolution time stamps,
4061 generalizing the earlier code that applied only to archive members.
4062 (f_mtime): Archive members always have low resolution time stamps.
4064 * configure.in: Remove --disable-nsec-timestamps, as this has
4065 been superseded by .LOW_RESOLUTION_TIME.
4067 2000-07-23 Paul Eggert <eggert@twinsun.com>
4069 * configure.in (enable_nsec_timestamps): Renamed from
4070 make_cv_nsec_timestamps, since enable/disable options
4071 shouldn't be cached.
4073 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4074 and Paul Eggert <eggert@twinsun.com>
4076 * file.c (file_timestamp_now):
4077 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4078 so that clock_gettime is not linked unless needed.
4080 * filedef.h (FILE_TIMESTAMP_HI_RES):
4081 Remove definition; "configure" now does this.
4083 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4084 to before high resolution file timestamp check,
4085 since that check now uses uintmax_t.
4086 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4087 high resolution file timestamps.
4088 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4089 so that we don't link in clock_gettime unnecessarily.
4091 2000-07-17 Paul D. Smith <psmith@gnu.org>
4093 * i18n/ja.po: New version of the translation file.
4095 2000-07-07 Paul D. Smith <psmith@gnu.org>
4097 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4098 the offset calculation.
4099 (name_mtime): Replace EINTR test with EINTR_SET macro.
4101 2000-07-07 Paul Eggert <eggert@twinsun.com>
4105 * remake.c (update_file_1):
4106 Avoid spurious rebuilds of archive members due to their
4107 timestamp resolution being only one second.
4108 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4109 the clock's resolution being lower than file timestamps'.
4110 When warning about future timestamps, report only the discrepancy,
4111 not the absolute value of the timestamp and the current time.
4113 * file.c (file_timestamp_now): New arg RESOLUTION.
4114 * filedef.h (file_timestamp_now): Likewise.
4115 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4117 2000-07-05 Paul D. Smith <psmith@gnu.org>
4119 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4120 to listp. Fixes PR/1793.
4122 2000-06-26 Paul Eggert <eggert@twinsun.com>
4124 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4126 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4128 * remake.c (f_mtime): Remove unused var memtime.
4130 2000-06-25 Martin Buchholz <martin@xemacs.org>
4132 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4133 Ran spell-check on make.texinfo.
4135 2000-06-23 Paul D. Smith <psmith@gnu.org>
4137 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4138 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4139 * make.h: Define these macros.
4141 * Version 3.79.1 released.
4143 * configure.in: Add a new option, --disable-nsec-timestamps, to
4144 avoid using sub-second timestamps on systems that support it. It
4145 can lead to problems, e.g. if your makefile relies on "cp -p".
4146 * README.template: Document the issue with "cp -p".
4148 * config.guess, config.sub: Updated.
