548 2009-11-12 Boris Kolpackov <boris@codesynthesis.com>
550 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
551 which allows the caller to get the index of the matching directory.
553 * make.h (vpath_search): Update prototype.
555 * remake.c (library_search): Implement linker-compatible library
556 search. Use the new VPATH_SEARCH index functionality to keep track
557 of the directory index for each match. Select the match with the
558 lowest directory index.
560 * implicit.c (pattern_search): Pass NULL for the index arguments in
561 the VPATH_SEARCH call.
563 * doc/make.texi (Directory Search for Link Libraries): Describe the
566 * NEWS: Add a note about the new behavior.
568 2009-10-25 Paul Smith <psmith@gnu.org>
570 * AUTHORS, et.al.: Update copyright years.
572 * implicit.c (stemlen_compare): Fix qsort() compare bug that
573 caused implicit rules with equal stem lengths to be sorted
576 2009-10-24 Paul Smith <psmith@gnu.org>
578 * main.c (usage): Add --eval to the usage string.
579 (switches): Add the --eval switch.
580 (main): If --eval is given, add them to the simply-expanded variable
581 -*-eval-flags-*- (necessary to allow recursion to work properly).
582 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
584 * NEWS: Describe the new --eval command line argument.
585 * doc/make.texi (Options Summary): Document --eval.
587 * dep.h: eval_buffer() returns void.
588 * read.c (eval_buffer): Ditto.
591 * variable.h (define_variable_cname): New macro for constant
593 * default.c (set_default_suffixes): Use it.
594 * main.c (main): Ditto.
595 (handle_non_switch_argument): Ditto.

597 * read.c (read_all_makefiles): Ditto.
598 * variable.c (define_automatic_variables): Ditto.
600 * commands.c (dep_hash_cmp): Avoid casts.
604 2009-10-22 Boris Kolpackov <boris@codesynthesis.com>
606 * read.c (read_all_makefiles): Mark the default makefile dependency
609 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
611 * read.c (do_undefine): Free the expanded variable name.
613 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
614 to normal upgrade logic from dep_hash_cmp to set_file_variables.
616 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
618 * dep.h (uniquize_deps): Remove.
620 * read.c (uniquize_deps): Merge into set_file_variables in
622 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
624 * commands.c (set_file_variables): Avoid modifying the dep
625 chain to achieve uniqueness. Fixes savannah bug 25780.
627 * implicit.c (pattern_search): Instead of re-setting all automatic
628 variables for each rule we try, just update $*.
630 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
632 * variable.h (undefine_variable_in_set): New function declaration.
633 (undefine_variable_global): New macro.
635 * variable.c (undefine_variable_in_set): New function implementation.
637 * read.c (vmodifiers): Add undefine_v modifier.
638 (parse_var_assignment): Parse undefine.
639 (do_undefine): Handle the undefine directive.

646 * NEWS: Add a note about the new directive.
648 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
650 * implicit.c (pattern_search): Initialize file variables only
651 if we need to parse a rule that requires the second expansion.
653 2009-10-03 Paul Smith <psmith@gnu.org>
655 * make.h: Include <alloca.h> even on systems where __GNUC__ is
656 defined. Not sure why it was done the other way.
657 Requested by David Boyce <dsb@boyski.com>.
659 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
661 * dep.h (dep): Add the DONTCARE bitfield.
663 * filedef.h (file):Add the NO_DIAG bitfield.
665 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
666 not struct file (a file can be a dependency of many targets,
667 some don't care, some do).
669 * remake.c (update_goal_chain): Propagate DONTCARE from struct
670 dep to struct file before updating the goal and restore it
672 (update_file): Don't prune the dependency graph if this target
673 has failed but the diagnostics hasn't been issued.
674 (complain): Scan the file's dependency graph to find the file
675 that caused the failure.
676 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
677 whether to print diagnostics.
679 Fixes Savannah bugs #15110, #25493, #12686, and #17740.

687 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
689 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
690 much of the command line on a single pass.
692 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
694 * varible.c (create_pattern_var): Insert variables into the
695 PATTERN_VARS list in the shortest patterns first order.
697 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
698 used to sort the rules.

712 2009-09-27 Paul Smith <psmith@gnu.org>
714 * doc/make.texi (Double-Colon): Mention that pattern rules with
715 double-colons have a different meaning. Savannah bug #27497.
717 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
719 * configh.dos.template: Remove unconditional definition of
720 SYS_SIGLIST_DECLARED.
721 Include <sys/version.h> because ports of GCC 4.3.0 and later no
722 longer include it, so macros like __DJGPP_MINOR__ are no longer
723 defined automatically.
725 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
726 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
727 instead of using the hardcoded ones.
728 (SUBDIRS): doc subdir added.
729 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
730 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
731 create html formated docs. texi2html may not be ported to DOS.
732 (make.info, make.dvi, make.ps, make.html): Make targets depend on
734 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
735 -I switch to look in ./ instead of ./doc.
736 (html): Target depend on html-recursive instead of make_1.html.
737 (make_1.html): Removed.
738 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
739 (all-recursive): Allow for more than one subdir in the build
741 (mostlyclean-recursive, clean-recursive, distclean-recursive)
742 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
743 (tags-recursive): Allow for more than one subdir in the build
745 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
746 targets. Enter into doc/ to produce the targets.
747 (all-am): $(INFO_DEPS) replaced by info.
749 2009-09-26 Paul Smith <psmith@gnu.org>
751 * read.c (record_files): Use free_ns() to free struct nameseq.
754 * rule.c (freerule): Use free_dep_chain().
756 * read.c (record_files): Free FILENAMES chain for implicit rules.
757 (eval): Static pattern targets go into the string cache.
759 * function.c (string_glob): Free NAME in the nameseq chain.
761 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
763 * implicit.c (pattern_search): Terminate early if we haven't
764 found any rules to try (performance improvement).
766 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
768 * implicit.c (pattern_search): Merge three parallel arrays,
769 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
770 of struct TRYRULE. In the old version the latter two arrays
771 had insufficient length.
773 2009-09-24 Paul Smith <psmith@gnu.org>
775 * implicit.c (pattern_search): Add back support for order-only
776 prerequisites for secondary expansion implicit rules, that were
777 accidentally dropped. If we find a "|", enable order-only mode
778 and set IGNORE_MTIME on all deps that are seen afterward.
779 (pattern_search): Fix memory leaks: for intermediate files where
780 we've already set the file variable and pattern variable sets, be
781 sure to either save or free them as appropriate.
783 2009-09-23 Paul Smith <psmith@gnu.org>
785 Rework the way secondary expansion is stored, for efficiency.
786 This changes secondary expansion so that ONLY WHEN we know we have
787 a possibility of needing secondary expansion, do we defer the
788 secondary expansion. This means more parsing the deps but we use
789 a lot less memory (due to the strcache). Also, this fixes
792 * read.c (eval): Don't parse the dep string here anymore.
793 (record_files): Take the dep argument as an unparsed string. If
794 secondary expansion is enabled AND the prereq string has a '$' in
795 it, then set NEED_2ND_EXPANSION and keep the entire string.
796 Otherwise, parse the dep string here to construct the dep list
797 with the names in the strcache.
799 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
800 duplicate the name string (others are in the strcache).
802 * implicit.c: Remove struct idep and free_idep_chain(): unused.
803 (struct patdeps): New structure to store prereq information.
804 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
805 which prerequisites need expansion, and expand only those.
807 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
808 and enter_prereqs(). split_prereqs() takes a fully-expanded string
809 and splits it into a DEP list, handling order-only prereqs.
810 (enter_prereqs): This function enters a list of DEPs into the file
811 database. If there's a stem defined, expand any pattern chars.
812 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
813 set. Use the above functions.
814 (snap_deps): Only perform second expansion on prereqs that need it,
815 as defined by the NEED_2ND_EXPANSION flag.
816 (print_prereqs): New function to print the prereqs
817 (print_file): Call print_prereqs() rather than print inline.
819 * hash.h (STRING_COMPARE): Take advantage of strcache() by
821 (STRING_N_COMPARE): Ditto.
822 (ISTRING_COMPARE): Ditto.
824 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
825 (parse_file_seq): Return void*
826 * read.c (parse_file_seq): Return void*.
827 (eval): Invoke macroized version of parse_file_seq()
828 * default.c (set_default_suffixes): Ditto.
829 * file.c (split_prereqs): Ditto.
830 * function.c (string_glob): Ditto.
831 * main.c (main): Ditto.
832 * rule.c (install_pattern_rule): Ditto.
834 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
836 2009-09-16 Paul Smith <psmith@gnu.org>
838 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
840 * dep.h: Create alloc_dep() / free_dep() macros.
842 * implicit.c (pattern_search): Take advantage of the new
843 parse_file_seq() to add the directory prefix to each prereq.
845 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
846 all. Avoid reversing chains. Support adding prefixes.
847 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
848 cached/non-cached results.
849 (eval): Remove multi_glob() & invoke new parse_file_seq().
850 * rule.c (install_pattern_rule): Ditto.
851 * main.c (main): Ditto.
852 * implicit.c (pattern_search): Ditto.
853 * function.c (string_glob): Ditto.
854 * file.c (parse_prereqs): Ditto.
855 * default.c (set_default_suffixes): Ditto.
857 * variable.c (parse_variable_definition): Don't run off the end of
858 the string if it ends in whitespace (found with valgrind).
860 * commands.c (set_file_variables): Keep space for all targets in
861 $? if -B is given (found with valgrind).
863 2009-09-15 Paul Smith <psmith@gnu.org>
865 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
866 (xcalloc): Add new function.
867 * make.h: New declarations.
869 * ar.c (ar_glob_match): New calling method for concat().
870 * main.c (main): Ditto.
871 (decode_env_switches): Ditto.
872 * read.c (eval_makefile): Ditto.
873 (tilde_expand): Ditto.
874 (parse_file_seq): Ditto.
875 * variable.c (target_environment): Ditto.
876 (sync_Path_environment): Ditto.
878 * ar.c (ar_glob_match): Use xcalloc().
879 * dir.c (file_impossible): Ditto.
880 * file.c (enter_file): Ditto.
881 * job.c (new_job): Ditto.
882 * read.c (parse_file_seq): Ditto.
883 * vmsfunctions.c (opendir): Ditto.
885 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
887 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
888 inside the loop that looks up environment for PATH.
890 2009-08-31 Eli Zaretskii <eliz@gnu.org>
892 * function.c (windows32_openpipe): Update envp after calling
893 sync_Path_environment.
895 2009-08-02 Paul Smith <psmith@gnu.org>
897 * remake.c (notice_finished_file): Ensure file->cmds is not null
898 before looping through them. Fixes Savannah bug #21824.
900 * doc/make.texi (Wildcard Examples): Clarify when objects is
901 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
902 (Include): Clarify the behavior of -include.
903 Fixes Savannah bug #18963.
905 2009-08-01 Paul Smith <psmith@gnu.org>
907 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
908 etc. come on the command line. Fixes Savannah bug #27093.
910 * expand.c (expand_argument): If the argument is large enough use
911 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
913 * variable.c (do_variable_definition): Avoid using alloca() to
914 hold values, which can be large. Fixes Savannah bug #23960.
916 * job.c (new_job): Use memmove() instead of strcpy() since both
917 pointers are in the same memory block. Fixes Savannah bug #27148.
918 Patch by Petr Machata.
920 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
922 * job.c (construct_command_argv_internal): Add "ulimit" and
923 "unset" to the sh_cmds for Unixy shells.
925 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
927 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
928 that set make_cv_sys_gnu_glob, so they are also correctly set
929 when the cache has been populated before.
931 2009-07-04 Eli Zaretskii <eliz@gnu.org>
933 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
934 exist, as realpath(3) does where it's supported.
936 2006-07-04 Eli Zaretskii <eliz@gnu.org>
938 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
939 (abspath): Support systems that define HAVE_DOS_PATHS (have
940 drive letters in their file names). Use IS_PATHSEP instead of a
941 literal '/' comparison. Fixes Savannah bug #26886.
943 2009-06-14 Paul Smith <psmith@gnu.org>
945 * remake.c (update_file_1): Remember the original file we marked
946 as updating, so we can clear that flag again. If we find a target
947 via vpath, FILE might change.
948 (check_dep): Ditto. Fixes Savannah bug #13529.
949 Patch by Reid Madsen <reid.madsen@tek.com>.
951 2009-06-13 Paul Smith <psmith@gnu.org>
953 * doc/make.texi (MAKEFILES Variable): Be explicit that files
954 included by MAKEFILES cannot give default goals.
955 * read.c (eval): If set_default is not set, pass the no-default-goal
956 value when we read included makefiles. Fixes Savannah bug #13401.
958 * ar.c (ar_name): Ensure that targets with empty parens aren't
959 considered archive member references: archive members must have a
960 non-empty "member" string. Fixes Savannah bug #18435.
962 * function.c (string_glob): Rely on multi_glob() to determine
963 whether files exist or not. Remove call to file_exists_p() which
964 is not always correct. Fixes Savannah bug #21231.
965 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
966 then only files that really exist will be returned.
967 * dep.h: Add new argument to multi_glob().
968 * rule.c (install_pattern_rule): Ditto.
969 * read.c (eval): Ditto.
970 * main.c (main): Ditto.
971 * implicit.c (pattern_search): Ditto.
972 * file.c (parse_prereqs): Ditto.
973 * default.c (set_default_suffixes): Ditto.
975 2009-06-09 Paul Smith <psmith@gnu.org>
977 * commands.c (set_file_variables): If always_make_flag is set,
978 always add the prereq to $?. Fixes Savannah bug #17825.
980 * remake.c (update_file_1): When rebuilding deps of FILE, also try
981 to rebuild the deps of all the also_make targets for that file.
982 Fixes Savannah bug #19108.
984 * implicit.c (pattern_search): Undo test for is_target, added by
985 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
986 Rule Search Algorithm". Fixes Savannah bug #17752.
988 * main.c (clean_jobserver): Clear the jobserver_fds options and
989 set job_slots to the default when we clean up.
990 (define_makeflags): Return the new MAKEFLAGS value.
991 (main): Reset MAKEFLAGS in the environment when we re-exec.
992 Fixes Savannah bug #18124.
994 2009-06-08 Paul Smith <psmith@gnu.org>
996 * read.c (eval): Collapse continuations post-semicolon on target-
997 specific variables. Fixes Savannah bug #17521.
999 2009-06-07 Paul Smith <psmith@gnu.org>
1001 * job.c (reap_children): For older systems without waitpid() (are
1002 there any of these left?) run wait(2) inside EINTRLOOP to handle
1003 EINTR errors. Fixes Savannah bug #16401.
1005 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1007 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1009 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1010 not the end, to catch second expansion $(eval ...) defining new
1011 target/prereq relationships during snap_deps.
1012 Fixes Savannah bug #24622.
1014 * read.c (record_files): The second-expansion "f->updating" hack
1015 was not completely correct: if assumed that the target with
1016 commands always had prerequisites; if one didn't then the ordering
1017 was messed up. Fixed for now to use f->updating to decide whether
1018 to preserve the last element in the deps list... but this whole
1019 area of constructing and reversing the deps list is too confusing
1020 and needs to be reworked. Fixes Savannah bug #21198.
1022 2009-06-06 Paul Smith <psmith@gnu.org>
1024 * hash.c (hash_insert): Remove useless test for NULL.
1025 Fixes Savannah bug #21823.
1027 * make.h: Move SET_STACK_SIZE determination to make.h.
1028 * main.c (main): New global variable, STACK_LIMIT, holds the
1029 original stack limit when make was started.
1030 * job.c (start_job_command): Reset the stack limit, if we changed it.
1031 Fixes Savannah bug #22010.
1033 * remake.c (check_dep): Only set the target's state to not-started
1034 if it's not already running. Found this while testing -j10 builds
1035 of glibc: various targets were being rebuilt multiple times.
1036 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1039 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1040 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1043 2009-06-04 Paul Smith <psmith@gnu.org>
1045 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1047 * maintMakefile: Modify access of config and gnulib Savannah
1048 modules to use GIT instead of CVS.
1050 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1051 Fixes Savannah bug #24655.
1053 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1054 this can happen during some invocations of $(eval ...) for example.
1055 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1057 2009-06-02 Paul Smith <psmith@gnu.org>
1059 * configure.in: Check for fileno()
1060 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1061 for the makefile file so invocations of $(shell ...) don't inherit it.
1062 Fixes Savannah bug #24277.
1064 2009-06-01 Paul Smith <psmith@gnu.org>
1066 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1067 expansion was handled incorrectly. Rework the default goal
1068 handling to save the variable only. Remove default_goal_file and
1070 * read.c (eval): Check default_goal_var, not default_goal_name.
1071 * read.c (record_target_var): Don't check default_goal_file here.
1073 2009-05-31 Paul Smith <psmith@gnu.org>
1075 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1076 it, and if the multi_glob() returns nothing (say it expanded to
1077 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1079 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1080 $(and ..) to the reference. Fixes Savannah bug #25694.
1082 * make.1: Be clear that some recipes will be executed even with -n.
1083 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1085 * doc/make.texi (Override Directive): Make more clear how
1086 overrides and appends interact.
1087 Elucidates part of Savannah bug #26207.
1089 * read.c (record_target_var): Don't reset the origin on
1090 target-specific variables; try_variable_definition() will handle
1091 this correctly. Fixes Savannah bug #26207.
1093 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1094 Fixes Savannah bug #25712.
1096 * implicit.c (pattern_search): Keep a pointer to the beginning of
1097 the filename and save that instead of the constructed pointer.
1098 Fixes Savannah bug #26593.

1101 2009-05-30 Paul Smith <psmith@gnu.org>
1103 * doc/make.texi (Multi-Line): Add a description of the new abilities
1104 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1105 "command sequence" vs. "recipe" syntax.
1106 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1107 after a define, to create variables with those flavors.
1109 2009-05-25 Paul Smith <psmith@gnu.org>
1111 Reworked the parser for variable assignments to allow multiple
1112 modifiers, and in any order. Also allows variable and
1113 prerequisites to be modifier names ('export', 'private', etc.)
1115 * NEWS: Add notes about user-visible changes.
1117 * read.c (struct vmodifiers): Remember what modifiers were seen.
1118 (parse_var_assignment): New function to parse variable assignments.

1137 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1138 Loop over an array of extensions, instead of duplicating the same
1139 code inline. Use SearchPath followed by CreateFile, instead of
1140 the obsolete OpenFile. Fixes Savannah bug #17277.
1141 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1142 to `find_file'. Fixes Savannah bug #25662.
1144 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1146 * function.c (func_shell): Don't close pipedes[1] if it is -1.

1152 -t with phony targets.
1154 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1156 Introduce a new keyword "private" which applies to target-specific
1157 variables and prevents their values from being inherited.

1187 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1189 * job.c (construct_command_argv_internal): Avoid extra backslash
1190 in batch-mode Unixy shells. Under DB_JOBS, display the contents

1196 -jN without Unixy shell. Remove obsolete text about not supplying
1197 Visual Studio project files (we do supply them). Modify text to
1198 prefer GCC builds to MSC builds.

1219 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1221 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1223 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1224 (TEXINFOS): Value changed to `doc/make.texi'.
1225 (.SUFFIXES): Use .texi instead of .texinfo.
1226 (make.info, make.dvi): Depend on doc/make.texi.
1227 (.texi.info): New target, instead of ".texinfo.info". Change -I
1228 switch to $(MAKEINFO) to look in doc/. Use --no-split.

1232 switch to $(MAKEINFO) to look in doc/.
1233 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

1236 (html, make_1.html): New targets.
1237 (.PHONY): Add "html".
1238 (.SUFFIXES): Add .html.
1240 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1242 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1243 HAVE_DECL_SYS_SIGLIST.
1245 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1246 build does not use child_execute_job.
1248 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1249 export the SHELL environment variable to the child.
1251 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1253 * config.h.W32: Include sys/types.h.
1254 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1256 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1257 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1260 2007-11-04 Paul Smith <psmith@gnu.org>
1262 * doc/make.texi: Convert references to "commands", "command
1263 lines", and "command script" to "recipe".
1265 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1268 2007-10-27 Bruno Haible <bruno@clisp.org>
1270 * remake.c (f_mtime): Print time difference values between 100 and
1271 ULONG_MAX in fixed-point notation rather than in exponention notation.
1273 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1275 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1276 a more complex value than a simple shell: if it's not a default
1277 shell now then expand it and see if is a default shell then.
1279 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1281 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1282 pathnames, with const strings.
1283 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1284 from the template (used for building from CVS, not a dist).
1286 2007-10-10 Paul Smith <psmith@gnu.org>
1288 * make.h: Add a prototype for w32_kill() (change suggested by

1303 2007-09-11 Paul Smith <psmith@gnu.org>
1305 * doc/make.texi (Special Variables): Moved this into the "How to
1306 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1307 (MAKEFILE_LIST) No longer a section; this was added into the
1308 "Special Variables" section.
1309 (Rule Introduction): Reference .RECIPEPREFIX.
1310 (Simple Makefile): Ditto.
1311 (Rule Syntax): Ditto.
1312 (Command Syntax): Ditto.
1313 (Error Messages): Ditto.
1315 2007-09-10 Paul Smith <psmith@gnu.org>
1317 * commands.c (print_commands): Don't print an extra line in the
1318 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1320 * read.c (construct_include_path): Add the full string to the cache; we
1321 were chopping the last char.
1323 * NEWS: Announce the .RECIPEPREFIX special variable.
1324 * variable.c (lookup_special_var): Rename from handle_special_var().
1325 (lookup_variable): Call the new name.
1326 (set_special_var): New function: handle setting of special variables.
1327 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1328 (do_variable_definition): Call it.
1329 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1330 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1331 * main.c (main): Create the .RECIPEPREFIX special variable.
1332 * read.c (eval): Remove the cmd_prefix characters from the command
1333 scripts here, so they're not stored in the commands array at all,
1334 rather than waiting and stripping them out during command construction.
1335 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1337 2007-08-15 Paul Smith <psmith@gnu.org>
1339 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1340 file has had the section info removed, so add some to make.texi
1341 before we include it.
1343 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1345 * remake.c (check_dep): Reset the target state for intermediate
1346 files. They might have been considered before but not updated
1347 then (order-only for example) but they will be this time.

1353 * function.c (func_shell): Call construct_command_argv with zero
1355 * job.c (construct_command_argv_internal): New argument FLAGS; all

1361 2007-07-13 Paul Smith <psmith@gnu.org>
1363 * file.c (expand_deps): Use variable_buffer as the start of the
1364 buffer, not the original pointer (in case it was reallocated).
1365 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1366 Fixes Savannah bug #20452.
1368 2007-07-04 Paul Smith <psmith@gnu.org>
1370 * (ALL FILES): Update to GPLv3.
1371 * (ALL FILES): Update copyright for 2007.

1382 "Expansion of a deferred"
1383 Fixes Savannah bug #20018.
1385 * expand.c (variable_expand_for_file): Preserve the value of
1386 reading_file rather than setting it to 0 at the end.

1389 2007-05-11 Paul Smith <psmith@gnu.org>
1391 * job.c (new_job): Add debug info to specify where make found the
1392 command script it is running to build a target.
1393 Fixes Savannah bug #18617.
1395 * default.c (default_suffixes,default_suffix_rules,default_variables):
1396 Add support for Objective C. Fixes Savannah bug #16389.
1397 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1399 * function.c (func_lastword): Initialize p.
1401 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1402 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1403 Dave Korn <dave.korn@artimi.com>
1405 2007-05-08 Paul Smith <psmith@gnu.org>
1407 Fix Savannah bug #19656:
1409 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1411 * make.h: Change all case-insensitive string compares to use
1412 strcasecmp() (from POSIX). If we don't have that but do have one
1413 of the others, define strcasecmp to be one of those instead. If
1414 we don't have any, declare a prototype for our own version.
1416 * misc.c (strcasecmp): Use this if we can't find any native
1417 case-insensitive string comparison function.
1418 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1419 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1421 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1422 strcasecmp() instead of stricmp().
1423 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1424 instead of strcmpi().
1425 * acinclude.m4: Remove the strcasecmp() check from here.
1427 2007-03-21 Paul Smith <psmith@gnu.org>
1429 * configure.in: Don't turn on case-insensitive file system support
1430 if --disable-... is given. Fixes Savannah bug #19348.
1432 2007-03-19 Paul Smith <psmith@gnu.org>
1434 * ALL: Use the strcache for all file name strings, or other
1435 strings which we will never free. The goal is to save memory by
1436 avoiding duplicate copies of strings. However, at the moment this
1437 doesn't save much memory in most situations: due to secondary
1438 expansion we actually save prerequisite lists twice (once before
1439 the secondary expansion, and then again after it's been parsed
1440 into individual file names in the dep list). We will resolve this
1441 in a future change, by doing the parsing up-front for targets
1442 where secondary expansion is not set.
1444 Moving things into the strcache also allows us to use const
1445 pointers in many more places.
1447 2007-01-03 Paul Smith <psmith@gnu.org>
1449 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1450 the function, not just the first. Fixes Savannah bug #18680.
1452 2006-11-18 Paul Smith <psmith@gnu.org>
1454 * strcache.c (strcache_add_len): Don't allocate a new buffer
1455 unless the string is not already nil-terminated. Technically this
1456 is a violation of the standard, since we may be passed an array
1457 that is not long enough to test one past. However, in make this
1458 is never true since we only use nil-terminated strings or
1459 sub-strings thereof.
1461 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1463 * main.c: New global cmd_prefix, defaults to '\t'.
1464 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1467 * dir.c: Constified.
1468 (dir_contents_file_exists_p): Check for an error return from
1469 readdir(), just in case.
1471 * commands.c: Constified.
1472 * default.c: Constified.
1473 * expand.c: Constified.
1474 * function.c: Partial constification.
1475 * variable.c: Partial constification.
1476 * vmsify.c: Constification. Hard to test this but I hope I didn't
1478 * vpath.c: Partial constification.
1479 * w32/pathstuff.c: Partial constification.
1481 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1483 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1484 backslashes and drive letters as absolute.
1486 2006-10-22 Paul Smith <psmith@gnu.org>
1488 * main.c (struct command_switch): Use const and void*.
1490 2006-10-21 Paul Smith <psmith@gnu.org>
1493 * arscan.c: Constified.
1495 2006-09-30 Paul Smith <psmith@gnu.org>
1497 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1498 point to lastword since the example was updated.
1499 Fixes Savannah bug #16304.
1500 (Secondary Expansion): Correct example description.
1501 Fixes Savannah bug #16468.
1502 (Makefile Contents): Clarify that comments cannot appear within
1503 variable references or function calls.
1504 Fixes Savannah bug #16577.
1505 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1506 Fixes Savannah bug #17701.
1507 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1509 prerequisites. Fixes Savannah bug #17880.
1510 (Rule Syntax): "lise" -> "list"
1511 (Multiple Rules): ... -> @dots{}
1512 (Splitting Lines): ditto.
1514 * remake.c (update_file_1): Prereqs that don't exist should be
1515 considered changed, for the purposes of $?.
1516 Fixes Savannah bug #16051.
1518 * make.1: Remove extraneous "+".
1519 Fixes Savannah bug #16652.
1521 2006-09-06 Paul D. Smith <psmith@gnu.org>
1523 * configure.in: Include sys/types.h when checking for sys/wait.h.

1527 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1530 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1531 Normally, it is defined in config.h.
1533 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1536 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1537 sh_chars_sh for Windows platforms that emulate Unix.
1539 2006-05-07 Paul D. Smith <psmith@gnu.org>
1541 * README.OS2.template: Updates provided by Andreas Buening
1542 <andreas.buening@nexgo.de>.
1544 2006-04-30 Paul D. Smith <psmith@gnu.org>
1546 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1547 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1549 2006-04-26 Paul D. Smith <psmith@gnu.org>
1551 * README.cvs: Add a reminder to notify the GNU translation robot.

1558 that don't have extended grep.
1559 (cvsclean): Use $(PERL) instead of perl.
1561 2006-04-09 Paul D. Smith <psmith@gnu.org>
1563 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1565 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1566 inner-scope variables don't mask outer-scope variables.
1568 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1569 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1570 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1571 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1572 values from memory allocation functions: they return void* and so
1573 don't need to be cast. Also remove (char *) casts of arguments to

1605 2006-04-01 Paul D. Smith <psmith@gnu.org>
1607 Version 3.81 released.
1609 * NEWS: Updated for 3.81.
1611 * README.cvs: Mention that vpath builds are not supported out of
1612 CVS. Fixes Savannah bug #16236.

1616 2006-03-26 Paul D. Smith <psmith@gnu.org>
1618 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1619 support from automake, as described in the Texinfo manual.
1621 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1623 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1624 with lastslash, since the latter points to filename, not to

1627 Declare and define sh_chars_sh[].
1629 2006-03-23 Paul D. Smith <psmith@gnu.org>
1631 * configure.in: Look for build.sh.in in $srcdir so it will be
1632 built for remote configurations as well.
1634 * Makefile.am: Make sure to clean up build.sh during distclean.
1635 Fixes Savannah bug #16166.
1637 * misc.c (log_access): Takes a const char *.
1638 * function.c (fold_newlines): Takes an unsigned int *.
1639 Both fixes for Savannah bug #16170.
1641 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1643 * implicit.c (pattern_search): Call set_file_variables only
1644 if we have prerequisites that need second expansion. Fixes
1645 Savannah bug #16140.
1647 2006-03-19 Paul D. Smith <psmith@gnu.org>
1649 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1650 memory on hosts that don't support it directly.

1662 2006-03-17 Paul D. Smith <psmith@gnu.org>
1664 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1665 allow multiple concurrent runs.
1666 Patch from Joseph Myers <joseph@codesourcery.com>
1668 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1670 * dep.h (struct dep): Add the stem field.
1671 * misc.c (alloc_dep, free_dep): New functions.
1672 (copy_dep_chain): Copy stem.
1673 (free_dep_chain): Use free_dep.
1674 * read.c (record_files): Store stem in the dependency line.
1675 * file.c (expand_deps): Use stem stored in the dependency line. Use
1676 free_dep_chain instead of free_ns_chain.
1677 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1678 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1679 * main.c (main, handle_non_switch_argument): Ditto.
1680 * remake.c (check_dep): Ditto.

1686 expanding the result, we expand (or not, if it's simple) each part
1688 (allocated_variable_append): Don't expand the final result.
1689 Fixes Savannah bug #15913.
1691 2006-03-09 Paul Smith <psmith@gnu.org>
1693 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1694 listed non-existent files as changed. Turns out there's a bug in
1695 the Linux kernel builds which means that this change causes
1696 everything to rebuild every time. We will re-introduce this fix
1697 in the next release, to give them time to fix their build system.
1698 Fixes Savannah bug #16002.
1699 Introduces Savannah bug #16051.
1701 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1708 locator function find_and_set_default_shell if SHELL came from the
1711 2006-02-20 Paul D. Smith <psmith@gnu.org>
1713 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1714 to be null; don't core in that case.
1716 2006-02-19 Paul D. Smith <psmith@gnu.org>
1718 * commands.c (set_file_variables): Realloc, not malloc, the static
1719 string values to avoid memory leaks.
1721 * expand.c (recursively_expand_for_file): Only set reading_file to
1722 an initialized value.
1724 * implicit.c (pattern_search): We need to make a copy of the stem
1725 if we get it from an intermediate dep, since those get freed.
1727 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1729 (enter_file) [VMS]: Ditto.
1730 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1734 * job.c (construct_command_argv_internal): Fix last change.
1736 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1737 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1738 the calls to _beginthreadex.
1740 * expand.c (recursively_expand_for_file): Initialize `save' to
1741 prevent compiler warnings.
1743 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1745 * job.c (construct_command_argv_internal): Don't create a temporary
1746 script/batch file if we are under -n. Call _setmode to switch the
1747 script file stream to text mode.
1749 2006-02-17 Paul D. Smith <psmith@gnu.org>
1751 * variable.c (merge_variable_set_lists): Don't try to merge the
1752 global_setlist. Not only is this useless, but it can lead to
1753 circularities in the linked list, if global_setlist->next in one
1754 list gets set to point to another list which also ends in
1756 Fixes Savannah bug #15757.
1758 2006-02-15 Paul D. Smith <psmith@gnu.org>
1760 Fix for Savannah bug #106.
1762 * expand.c (expanding_var): Keep track of which variable we're
1763 expanding. If no variable is being expanded, it's the same as
1765 * make.h (expanding_var): Declare it.
1766 * expand.c (recursively_expand_for_file): Set expanding_var to the
1767 current variable we're expanding, unless there's no file info in
1768 it (could happen if it comes from the command line or a default
1769 variable). Restore it before we exit.
1770 * expand.c (variable_expand_string): Use the expanding_var file
1771 info instead of the reading_file info.
1772 * function.c (check_numeric): Ditto.

1777 (handle_function): Ditto.
1779 2006-02-14 Paul D. Smith <psmith@gnu.org>
1781 * read.c (eval): Even if the included filenames expands to the
1782 empty string we still need to free the allocated buffer.
1784 * implicit.c (pattern_search): If we allocated a variable set for
1785 an impossible file, free it.
1786 * variable.c (free_variable_set): New function.
1787 * variable.h: Declare it.
1789 * read.c (read_all_makefiles): Makefile names are kept in the
1790 strcache, so there's never any need to alloc/free them.
1793 * main.c (main): Add "archives" to the .FEATURES variable if
1794 archive support is enabled.
1795 * doc/make.texi (Special Variables): Document it.
1797 2006-02-13 Paul D. Smith <psmith@gnu.org>
1799 * implicit.c (pattern_search): Add checking for DOS pathnames to

1805 * (ALL FILES): Updated copyright and license notices.
1807 2006-02-10 Paul D. Smith <psmith@gnu.org>
1809 A new internal capability: the string cache is a read-only cache
1810 of strings, with a hash table interface for fast lookup. Nothing
1811 in the cache will ever be freed, so there's no need for reference
1812 counting, etc. This is the beginning of a full solution for
1813 Savannah bug #15182, but for now we only store makefile names here.
1815 * strcache.c: New file. Implement a read-only string cache.
1816 * make.h: Add prototypes for new functions.
1817 * main.c (initialize_global_hash_tables): Initialize the string cache.
1818 (print_data_base): Print string cache stats.
1819 * read.c (eval_makefile): Use the string cache to store makefile
1820 names. Rewrite the string allocation to be sure we free everything.
1822 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1824 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1825 directory time stamp didn't change, except on FAT filesystems.
1826 Suggested by J. David Bryan <jdbryan@acm.org>.
1828 2006-02-09 Paul D. Smith <psmith@gnu.org>
1830 * function.c (func_or): Implement a short-circuiting OR function.
1831 (func_and): Implement a short-circuiting AND function.
1832 (function_table_init): Update the table with the new functions.
1833 * doc/make.texi (Conditional Functions): Changed the "if" section
1834 to one on general conditional functions. Added documentation for
1835 $(and ...) and $(or ...) functions.
1836 * NEWS: Note new $(and ...) and $(or ...) functions.

1847 * vpath.c (selective_vpath_search): If the file we find has a
1848 timestamp from -o or -W, use that instead of the real time.
1849 * remake.c (f_mtime): If the mtime is a special token from -o or
1850 -W, don't overwrite it with the real mtime.
1851 Fixes Savannah bug #15341.
1853 Updates from Markus Mauhart <qwe123@chello.at>:

1857 invalid handle values.
1858 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1859 manage invalid handles; remove them.

1869 * filedef.h (struct file): Add a new LAST pointer.
1871 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1872 the comparison. For 64-bits systems the result of the subtraction
1873 might not fit into an int. Use comparison instead.
1874 Fixes Savannah bug #15534.
1876 * doc/make.texi: Update the chapter on writing commands to reflect
1877 the changes made in 3.81 for backslash/newline and SHELL handling.

1897 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1899 * remake.c (update_goal_chain): Set g->changed instead of
1900 incrementing it, as it is only 8-bit wide, and could overflow if

1923 the shell is not sh.exe.
1925 * job.c (create_batch_file): Renamed from create_batch_filename;
1926 all callers changed. Don't close the temporary file; return its
1927 file descriptor instead. New arg FD allows to return the file
1929 (construct_command_argv_internal): Use _fdopen instead of fopen to
1930 open the batch file.
1932 2006-01-04 Paul D. Smith <psmith@gnu.org>

1962 handling of backslash-newline sequences. Mention the differences
1963 on MS-DOS and MS-Windows.
1965 * NEWS: More details about building the MinGW port and a pointer
1966 to README.W32. Fix the section name that describes the new
1967 backward-incompatible processing of backslash-newline sequences.
1968 The special processing of SHELL set to "cmd" is only relevant to
1969 MS-Windows, not MS-DOS.
1971 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1973 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1974 to DWORD, to avoid compiler warnings.

1999 2005-12-11 Paul D. Smith <psmith@gnu.org>
2001 * implicit.c (pattern_search): If 2nd expansion is not set for
2002 this implicit rule, replace the pattern with the stem directly,
2003 and don't re-expand the variable list. Along with the other

2068 2005-10-16 Paul D. Smith <psmith@gnu.org>
2070 * main.c (main): Set CURDIR to be a file variable instead of a
2071 default, so that values of CURDIR inherited from the environment
2072 won't override the make value.
2074 2005-09-26 Paul D. Smith <psmith@gnu.org>
2076 * job.c (construct_command_argv_internal): If the line is empty
2077 remember to free the temporary argv strings.
2080 2005-09-16 Paul D. Smith <psmith@gnu.org>
2082 * job.c (start_job_command): The noerror flag is a boolean (single
2083 bit); set it appropriately.

2093 * read.c (record_files): Move code that sets stem for static
2094 pattern rules out of the if (!two_colon) condition so it is
2095 also executed for two-colon rules. Fixes Savannah bug #13881.
2097 2005-08-08 Paul D. Smith <psmith@gnu.org>
2099 * make.h: Don't test that __STDC__ is non-0. Some compilers
2100 (Windows for example) set it to 0 to denote "ISO C + extensions".
2103 2005-08-07 Paul D. Smith <psmith@gnu.org>
2105 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2106 conditional (slightly different version of a fix from Eli).
2108 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2109 If make is running in parallel without -k and two jobs die in a
2110 row, but not too close to each other, then make will quit without
2111 waiting for the rest of the jobs to die.
2113 * main.c (die): Don't reset err before calling reap_children() the
2114 second time: we still want it to be in the error condition.
2115 * job.c (reap_children): Use a static variable, rather than err,
2116 to control whether or not the error message should be printed.
2118 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2120 * w32/subproc/sub_proc.c: Include signal.h.
2121 (process_pipe_io, process_file_io): Pass a pointer to a local
2122 DWORD variable to GetExitCodeProcess. If the exit code is
2123 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2125 * job.c [WINDOWS32]: Include windows.h.
2126 (main_thread) [WINDOWS32]: New global variable.
2127 (reap_children) [WINDOWS32]: Get the handle for the main thread
2128 and store it in main_thread.
2130 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2131 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2132 doing anything else. When we are done, close the main thread
2133 handle and exit with status 130.
2135 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2137 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2140 * main.c (find_and_set_default_shell): If found a DOSish shell,
2141 set sh_found and the value of default_shell, and report the
2142 findings in debug mode.
2144 * job.c (construct_command_argv_internal): Check unixy_shell, not
2145 no_default_sh_exe, to decide whether to use Unixy or DOSish
2148 * README.W32: Update with info about the MinGW build.
2150 * build_w32.bat: Support MinGW.
2152 * w32/subproc/build.bat: Likewise.
2154 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2155 printing DWORD args.
2157 * function.c (windows32_openpipe): Fix format strings for printing
2160 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2162 (start_job_command): Fix format string for printing the result of
2164 (start_job_command) [WINDOWS32]: Do not define.
2165 (exec_command): Fix format string for printing HANDLE args.
2167 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2168 to avoid compiler warnings.
2169 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2170 (Note: some of these fixes were submitted independently by J. Grant)
2172 2005-07-30 J. Grant <jg@jguk.org>
2174 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2175 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2176 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2178 2005-07-15 Paul Smith <psmith@gnu.org>
2180 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2181 we don't have a POSIX shell, then revert to the old
2182 backslash-newline behavior (where they are stripped).
2185 2005-07-08 Paul D. Smith <psmith@gnu.org>
2187 * config.h.W32.template: Reorder to match the standard config.h,
2188 for easier comparisons.
2189 From J. Grant <jg@jguk.org>
2191 * maintMakefile: Remove .dep_segment before overwriting it, in
2192 case it's not writable or noclobber is set.
2193 * expand.c (variable_expand_string): Cast result of pointer
2194 arithmetic to avoid a warning.
2195 * main.c (switches): Add full-fledged final initializer.
2197 2005-07-06 Paul D. Smith <psmith@gnu.org>
2199 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2200 * signame.c (strsignal): If we found _sys_siglist[] or
2201 __sys_siglist[] use those instead of sys_siglist[].
2202 From Albert Chin <china@thewrittenword.com>
2204 2005-07-04 Paul D. Smith <psmith@gnu.org>
2206 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2207 globfree(); set up to use the GNU versions.
2208 From Martin Zinser <zinser@zinser.no-ip.info>
2210 2005-07-03 Paul D. Smith <psmith@gnu.org>
2212 From J. Grant <jg@jguk.org>:
2214 * README.W32.template: Update the Windows and tested MSVC versions.
2215 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2216 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2217 * build_w32.bat: Ditto.
2218 * w32/subproc/build.bat: Ditto.
2220 2005-06-28 Paul D. Smith <psmith@gnu.org>
2222 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2223 declaration was checked but not present.
2225 2005-06-27 Paul D. Smith <psmith@gnu.org>
2227 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2228 to unsigned long. Fixes Savannah bug #13550.
2230 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2231 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2232 Fixes Savannah bug #13551.
2234 2005-06-26 Paul D. Smith <psmith@gnu.org>
2236 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2237 it if ANSI_STRING is not set.
2239 2005-06-25 Paul D. Smith <psmith@gnu.org>
2241 * read.c (eval): If no filenames are passed to any of the
2242 "include" variants, don't print an error.
2243 * doc/make.texi (Include): Document this.
2244 Fixes Savannah bug #1761.
2246 * job.c (construct_command_argv_internal): Sanitize handling of
2247 backslash/newline pairs according to POSIX: that is, keep the
2248 backslash-newline in the command script, but remove a following
2249 TAB character, if present. In the fast path, make sure that the
2250 behavior matches what the shell would do both inside and outside
2251 of quotes. In the slow path, quote the backslash and put a
2252 literal newline in the string.
2253 Fixes Savannah bug #1332.
2254 * doc/make.texi (Execution): Document the new behavior and give
2256 * NEWS: Make a note of the new behavior.
2258 * make.h [WINDOWS32]: #include <direct.h>.
2259 Fixes Savannah bug #13478.
2261 * remake.c (name_mtime): If the stat() of a file fails and the -L
2262 option was given and the file is a symlink, take the best mtime of
2263 the symlink we can get as the mtime of the file and don't fail.
2264 Fixes Savannah bug #13280.
2266 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2267 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2268 inside a variable reference. Make this function static as it's
2270 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2271 parsing an unexpanded line looking for semicolons.
2272 Fixes Savannah bug #1454.
2273 * misc.c (remove_comments): Move this to read.c and make it static
2274 as it's only used there. Call find_char_unquote() with new arg.
2275 * make.h: Remove prototypes for find_char_unquote() and
2276 remove_comments() since they're static now.
2278 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2279 its export flag and obtain its value. When we need to re-exec,
2280 increment the value and add it into the environment.
2281 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2282 * NEWS: Mention MAKE_RESTARTS.
2283 * main.c (always_make_set): New variable. Change the -B option to
2284 set this one instead.
2285 (main): When checking makefiles, only set always_make_flag if
2286 always_make_set is set AND the restarts flag is 0. When building
2287 normal targets, set it IFF always_make_set is set.
2288 (main): Avoid infinite recursion with -W, too: only set what-if
2289 files to NEW before we check makefiles if we've never restarted
2290 before. If we have restarted, set what-if files to NEW _after_ we
2292 Fixes Savannah bug #7566:
2294 2005-06-17 Paul D. Smith <psmith@gnu.org>
2296 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2297 in the prerequisites list.
2299 2005-06-12 Paul D. Smith <psmith@gnu.org>
2301 Fix Savannah bug # 1328.
2303 * configure.in: Check for atexit().
2304 * misc.c (close_stdout): Test stdout to see if writes to it have
2305 failed. If so, be sure to exit with a non-0 error code. Based on
2306 code found in gnulib.
2307 * make.h: Prototype.
2308 * main.c (main): Install close_stdout() with atexit().
2310 2005-06-10 Paul D. Smith <psmith@gnu.org>
2312 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2314 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2315 headers; make vmsWaitForChildren() static; extern vmsify().
2316 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2317 Don't create child_execute_job() here (it's in vmsjobs.c).
2318 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2320 2005-06-09 Paul D. Smith <psmith@gnu.org>
2322 * variable.c (push_new_variable_scope): File variables point
2323 directly to the global_setlist variable. So, inserting a new
2324 scope in front of that has no effect on those variables: they
2325 don't go through current_variable_set_list. If we're pushing a
2326 scope and the current scope is global, push it "the other way" so
2327 that the new setlist is in the global_setlist variable, and
2328 next points to a new setlist with the global variable set.
2329 (pop_variable_scope): Properly undo a push with the new
2331 Fixes Savannah bug #11913.
2333 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2335 * job.c (reap_children): Don't die of the command failed but
2336 the dontcare flag is set. Fixes Savannah bug #13216.
2338 * implicit.c (pattern_search): When creating a target from
2339 an implicit rule match, lookup pattern target and set precious
2340 flag in a newly created target. Fixes Savannah bug #13218.
2342 2005-05-13 Paul D. Smith <psmith@gnu.org>
2344 Implement "if... else if... endif" syntax.
2346 * read.c (eval): Push all checks for conditional words ("ifeq",
2347 "else", etc.) down into the conditional_line() function.
2348 (conditional_line): Rework to allow "else if..." clause. New
2349 return value -2 for lines which are not conditionals. The
2350 ignoring flag can now also be 2, which means "already parsed a
2351 true branch". If that value is seen no other branch of this
2352 conditional can be considered true. In the else parsing if there
2353 is extra text after the else, invoke conditional_line()
2354 recursively to see if it's another conditional. If not, it's an
2355 error. If so, raise the conditional value to this level instead
2356 of creating a new conditional nesting level. Special check for
2357 "else" and "endif", which aren't allowed on the "else" line.
2358 * doc/make.texi (Conditional Syntax): Document the new syntax.
2360 2005-05-09 Paul D. Smith <psmith@gnu.org>
2362 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2363 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2364 recurses to the w32 directory, even on non-Windows systems. Use
2365 the method suggested in the automake manual.
2366 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2367 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2369 2005-05-07 Paul D. Smith <psmith@gnu.org>
2371 * main.c (die): If we're dying with a fatal error (not that a
2372 command has failed), write back any leftover tokens before we go.
2374 * job.c (set_child_handler_action_flags): If there are jobs
2375 waiting for the load to go down, set an alarm to go off in 1
2376 second. This allows us to wake up from a potentially long-lasting
2377 read() and start a new job if the load has gone down. Turn it off
2379 (job_noop): Dummy signal handler function.
2380 (new_job): Invoke it with the new semantics.
2382 * docs/make.texi: Document secondary expansion. Various cleanups
2385 2005-05-03 Paul D. Smith <psmith@gnu.org>
2387 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2388 the targets which are to ultimately be made are called "goals";
2389 see the GNU make manual. Also, MAKECMDGOALS, etc.
2391 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2392 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2393 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2395 2005-05-02 Paul D. Smith <psmith@gnu.org>
2397 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2398 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2399 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2400 functions to vmsjobs.c. #include it into jobs.c.
2402 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2403 jobserver tokens. I found that this happens when an exported
2404 recursive variable contains a $(shell ...) function reference: in
2405 this situation we could "forget" to write back a token.
2407 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2408 we have. It's not reliable to depend on the number of children in
2409 our linked list so keep a separate count.
2410 (new_job): Check jobserver_tokens rather than children &&
2411 waiting_jobs. Increment jobserver_tokens when we get one.
2412 (free_child): If jobserver_tokens is 0, internal error. If it's
2413 >1, write a token back to the jobserver pipe (we don't write a
2414 token for the "free" job). Decrement jobserver_tokens.
2416 * main.c: Add variable master_job_slots.
2417 (main): Set it to hold the number of jobs requested if we're the
2418 master process, when using the jobserver.
2419 (die): Sanity checks: first test jobserver_tokens to make sure
2420 this process isn't holding any tokens we didn't write back.
2421 Second, if master_job_slots is set count the tokens left in the
2422 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2424 2005-04-24 Paul D. Smith <psmith@gnu.org>
2426 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2427 with -l# can lose jobserver tokens, because waiting jobs are not
2428 consulted properly when checking for the "free" token.
2430 * job.c (free_child): Count waiting_jobs as having tokens.
2431 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2432 handle jobs waiting for the load to drop.
2434 2005-04-23 Paul D. Smith <psmith@gnu.org>
2436 * main.c (main): Be careful to not core if a variable setting in
2437 the environment doesn't contain an '='. This is illegal but can
2438 happen in broken setups.
2439 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2441 2005-04-12 Paul D. Smith <psmith@gnu.org>
2443 The second expansion feature causes significant slowdown. Timing
2444 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2445 read the makefile before the feature, to 11+s to do the same
2446 operations after the feature. Additionally, memory usage
2447 increased drastically. To fix this I added some intelligence that
2448 avoids the overhead of the second expansion unless it's required.
2450 * dep.h: Add a new boolean field, need_2nd_expansion.
2452 * read.c (eval): When creating the struct dep for the target,
2453 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2454 (record_files): If there's a "%" in a static pattern rule, it gets
2455 converted to "$*" so set need_2nd_expansion to 1.
2457 * file.c (expand_deps): Rework to be more efficient. Only perform
2458 initialize_file_variables(), set_file_variables(), and
2459 variable_expand_for_file() if the need_2nd_expansion is set.
2461 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2462 (pattern_search): Ditto.
2463 * main.c (handle_non_switch_argument): Ditto.
2465 * read.c (read_all_makefiles): Ditto.
2466 (eval_makefile): Ditto.
2468 2005-04-07 Paul D. Smith <psmith@gnu.org>
2470 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2471 * variable.c (sync_Path_environment): Ditto.
2472 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2474 * main.c (main): Define the .FEATURES variable.
2475 * NEWS: Announce .FEATURES.
2476 * doc/make.texi (Special Variables): Document .FEATURES.
2478 * remake.c (check_dep): If a file is .PHONY, update it even if
2479 it's marked intermediate. Fixes Savannah bug #12331.
2481 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2483 * file.c (expand_deps): Factor out the second expansion and
2484 prerequisite line parsing logic from snap_deps().
2486 * file.c (snap_deps): Use expand_deps(). Expand and parse
2487 prerequisites of the .SUFFIXES special target first. Fixes
2488 Savannah bug #12320.
2490 2005-03-13 Paul D. Smith <psmith@gnu.org>
2492 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2495 2005-03-11 Paul D. Smith <psmith@gnu.org>
2497 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2498 available, not undefined (from Earnie Boyd).
2500 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2502 * implicit.c (pattern_search): Mark an intermediate target as
2503 precious if it happened to be a prerequisite of some (other)
2504 target. Fixes Savannah bug #12267.
2506 2005-03-09 Paul D. Smith <psmith@gnu.org>
2508 * read.c (eval_makefile): Add alloca(0).
2509 (eval_buffer): Ditto.
2511 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2513 * main.c (main): Use o_file instead of o_default when defining
2514 the .DEFAULT_TARGET special variable.
2515 * read.c (eval): Use define_variable_global() instead of
2516 define_variable() when setting new value for the .DEFAULT_TARGET
2517 special variable. Fixes Savannah bug #12266.
2519 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2521 * imlicit.c (pattern_search): Mark files for which an implicit
2522 rule has been found as targets. Fixes Savannah bug #12202.
2524 2005-03-04 Paul D. Smith <psmith@gnu.org>
2527 * doc/make.texi (Automatic Variables): Document $|.
2529 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2531 * read.c (record_files): Instead of substituting % with
2532 actual stem value in dependency list replace it with $*.
2533 This fixes stem triple expansion bug.
2535 * implicit.c (pattern_search): Copy stem to a separate
2536 buffer and make it a properly terminated string. Assign
2537 this buffer instead of STEM (which is not terminated) to
2538 f->stem. Instead of substituting % with actual stem value
2539 in dependency list replace it with $*. This fixes stem
2540 triple expansion bug.
2542 2005-03-01 Paul D. Smith <psmith@gnu.org>
2544 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2545 on Windows, as it takes a handle not a pid. Just exit.
2546 Fix from patch #3679, provided by Alessandro Vesely.
2548 * configure.in: Update check for sys_siglist[] from autoconf manual.
2549 * signame.c (strsignal): Update to use the new autoconf macro.
2551 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2553 * read.c (record_files): Add a check for the list of prerequisites
2554 of a static pattern rule being empty. Fixes Savannah bug #12180.
2556 2005-02-28 Paul D. Smith <psmith@gnu.org>
2558 * doc/make.texi (Text Functions): Update docs to allow the end
2559 ordinal for $(wordlist ...) to be 0.
2560 * function.c (func_wordlist): Fail if the start ordinal for
2561 $(wordlist ...) is <1. Matches documentation.
2562 Resolves Savannah support request #103195.
2564 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2565 previously we were stopping when !-q, exactly the opposite. This
2566 has been wrong since version 1.34, in 1994!
2567 (update_file): If we got an error don't break out to run more
2568 double-colon rules: just return immediately.
2569 Fixes Savannah bug #7144.
2571 2005-02-27 Paul D. Smith <psmith@gnu.org>
2573 * misc.c (end_of_token): Make argument const.
2574 * make.h: Update prototype.
2576 * function.c (abspath, func_realpath, func_abspath): Use
2577 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2578 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2579 * read.c (record_files): Ditto.
2580 * variable.c (do_variable_definition): Ditto.
2582 * function.c (func_error): Create a new function $(info ...) that
2583 simply prints the message to stdout with no extras.
2584 (function_table_init): Add new function to the table.
2585 * NEWS: Add $(info ...) reference.
2586 * doc/make.texi (Make Control Functions): Document it.
2588 New feature: if the system supports symbolic links, and the user
2589 provides the -L/--check-symlink-time flag, then use the latest
2590 mtime between the symlink(s) and the target file.
2592 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2593 readlink(). If both are available, define MAKE_SYMLINKS.
2594 * main.c: New variable: check_symlink_flag.
2595 (usage): Add a line for -L/--check-symlink-times to the help string.
2596 (switches): Add -L/--check-symlink-times command line argument.
2597 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2598 print a warning and disable it again.
2599 * make.h: Declare check_symlink_flag.
2600 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2601 if the file is a symlink then check each link in the chain and
2602 choose the NEWEST mtime we find as the mtime for the file. The
2603 newest mtime might be the file itself!
2604 * NEWS: Add information about this new feature.
2605 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2607 Avoid core dumps described in Savannah bug # 12124:
2609 * file.c: New variable snapped_deps remember whether we've run
2611 (snap_deps): Set it.
2612 * filedef.h: Extern it.
2613 * read.c (record_files): Check snapped_deps; if it's set then
2614 we're trying to eval a new target/prerequisite relationship from
2615 within a command script, which we don't support. Fatal.
2617 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2619 Implementation of the .DEFAULT_TARGET special variable.
2621 * read.c (eval): If necessary, update default_target_name when
2623 * read.c (record_files): Update default_target_file if
2624 default_target_name has changed.
2625 * main.c (default_target_name): Define.
2626 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2627 default_target_name is set use default_target_file as a root
2629 * filedef.h (default_target_name): Declare.
2630 * dep.h (free_dep_chain):
2631 * misc.c (free_dep_chain): Change to operate on struct nameseq
2632 and change name to free_ns_chain.
2633 * file.c (snap_deps): Update to use free_ns_chain.
2635 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2637 Implementation of the second expansion in explicit rules,
2638 static pattern rules and implicit rules.
2640 * read.c (eval): Refrain from chopping up rule's dependencies.
2641 Store them in a struct dep as a single dependency line. Remove
2642 the code that implements SySV-style automatic variables.
2644 * read.c (record_files): Adjust the code that handles static
2645 pattern rules to expand all percents instead of only the first
2646 one. Reverse the order in which dependencies are stored so that
2647 when the second expansion reverses them again they appear in
2648 the makefile order (with some exceptions, see comments in
2649 the code). Remove the code that implements SySV-style automatic
2652 * file.c (snap_deps): Implement the second expansion and chopping
2653 of dependency lines for explicit rules.
2655 * implicit.c (struct idep): Define an auxiliary data type to hold
2656 implicit rule's dependencies after stem substitution and
2659 * implicit.c (free_idep_chain): Implement.
2661 * implicit.c (get_next_word): Implement helper function for
2662 parsing implicit rule's dependency lines into words taking
2663 into account variable expansion requests. Used in the stem
2666 * implicit.c (pattern_search): Implement the second expansion
2667 for implicit rules. Also fixes bug #12091.
2669 * commands.h (set_file_variables): Declare.
2670 * commands.c (set_file_variables): Remove static specifier.
2672 * dep.h (free_dep_chain): Declare.
2673 * misc.c (free_dep_chain): Implement.
2675 * variable.h (variable_expand_for_file): Declare.
2676 * expand.c (variable_expand_for_file): Remove static specifier.
2678 * make.h (strip_whitespace): Declare.
2679 * function.c (strip_whitespace): Remove static specifier.
2681 2005-02-26 Paul D. Smith <psmith@gnu.org>
2683 * main.c (main): Check for ferror() when reading makefiles from stdin.
2684 Apparently some shells in Windows don't close pipes properly and
2687 2005-02-24 Jonathan Grant <jg@jguk.org>
2689 * configure.in: Add MinGW configuration options, and extra w32 code
2691 * Makefile.am: Add MinGW configuration options, and extra w32 code
2693 * main.c: Determine correct program string (after last \ without .exe).
2694 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2696 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2697 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2698 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2699 environment support.
2701 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2703 * function.c (func_shell): When initializing error_prefix, check
2704 that reading file name is not null. This fixes long-standing
2705 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2707 2005-02-09 Paul D. Smith <psmith@gnu.org>
2709 * maintMakefile: Update the CVS download URL to simplify them.
2710 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2711 downloading the .texi files from Savannah now.
2713 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2715 * main.c (handle_non_switch_argument): Only add variables to
2716 command_variables if they're not already there: duplicate settings
2717 waste space and can be confusing to read.
2719 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2720 this header is never included by non-WINDOWS32 code, and it
2721 requires <config.h> to define which isn't always included first.
2723 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2724 testing MINGW32 versions.
2726 * main.c (log_working_directory): flush stdout to be sure the WD
2727 change is printed before any stderr messages show up.
2729 2005-02-01 Paul D. Smith <psmith@gnu.org>
2731 * maintMakefile (po_repo): Update the GNU translation site URL.
2733 2004-12-01 Paul D. Smith <psmith@gnu.org>
2735 * main.c (main): Change char* env_shell to struct variable shell_var.
2736 * variable.c (target_environment): Use new shell_var.
2738 2004-11-30 Paul D. Smith <psmith@gnu.org>
2740 * configure.in: The old way we avoided creating build.sh from
2741 build.sh.in before build.sh.in exists doesn't work anymore; we
2742 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2743 the help!). This also keeps automake from complaining.
2744 * Makefile.am (README): Add a dummy target so automake won't
2745 complain that this file doesn't exist when we checkout from CVS.
2746 * maintMakefile (.dep_segment): Rewrite this rule since newer
2747 versions of automake don't provide DEP_FILES.
2749 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2751 Implementation of `realpath' and `abspath' built-in functions.
2753 * configure.in: Check for realpath.
2754 * function.c (abspath): Return an absolute file name that does
2755 not contain any `.' or `..' components, nor repeated `/'.
2756 * function.c (func_abspath): For each name call abspath.
2757 * function.c (func_realpath): For each name call realpath
2758 from libc or delegate to abspath if realpath is not available.
2759 * doc/make.texi (Functions for File Names): Document new functions.
2760 * doc/make.texi (Quick Reference): Ditto.
2762 2004-11-28 Paul D. Smith <psmith@gnu.org>
2764 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2765 arguments. Fixes bug #10252.
2767 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2769 * main.c (main): Set SHELL to v_noexport by default. Remember the
2770 original environment setting of SHELL in the env_shell variable.
2771 * main.h: Export new env_shell variable.
2772 * variable.c (target_environment): If we find a v_noexport
2773 variable for SHELL, add a SHELL variable with the env_shell value.
2774 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2775 * doc/make.texi (Variables/Recursion): Ditto.
2777 2004-11-28 Paul D. Smith <psmith@gnu.org>
2779 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2780 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2781 Patch by Alessandro Vesely.
2783 2004-11-12 Paul D. Smith <psmith@gnu.org>
2785 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2786 the command line if it's inside a string.
2787 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2789 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2791 * function.c (func_lastword): New function: return last word
2792 from the list of words.
2793 * doc/make.texi: Document $(lastword ). Fix broken links in
2794 Quick Reference section.
2796 2004-10-06 Paul D. Smith <psmith@gnu.org>
2798 Apply patch from Alessandro Vesely, provided with bug # 9748.
2799 Fix use of tmpnam() to work with Borland C.
2801 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2802 construction of a temporary filename, and call new function
2803 create_batch_filename().
2804 (create_batch_filename) [WINDOWS32]: New function to create a
2807 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2809 * read.c (record_target_var): Expand simple pattern-specific
2811 * variable.c (initialize_file_variables): Do not expand simple
2812 pattern-specific variable.
2814 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2816 * remake.c (update_file_1): When rebuilding makefiles inherit
2817 dontcare flag from a target that triggered update.
2819 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2821 * variable.c (initialize_file_variables): Mark pattern-specific
2822 variable as a per-target and copy export status.
2824 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2826 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2828 * implicit.c (pattern_search): When considering an implicit rule's
2829 prerequisite check that it is actually a target rather then
2830 just an entry in the file hashtable.
2832 2004-09-21 Paul D. Smith <psmith@gnu.org>
2834 * read.c (readstring): Fix some logic errors in backslash handling.
2835 (eval): Remove some unnecessary processing in buffer handling.
2836 (record_target_var): Assert that parse_variable_definition() succeeded.
2837 Reported by: Markus Mauhart <qwe123@chello.at>.
2839 * misc.c: Removed the sindex() function. All instances of this
2840 function were trivially replaceable by the standard strstr()
2841 function, and that function will always have better (or certainly
2842 no worse) performance than the very simple-minded algorithm
2843 sindex() used. This can matter with complex makefiles.
2844 * make.h: Remove the prototype for sindex().
2845 * function.c (subst_expand): Convert sindex() call to strstr().
2846 This means we no longer need to track the TLEN value so remove that.
2847 (func_findstring): Convert sindex() to strstr().
2848 * commands.c (chop_commands): Convert sindex() calls to strstr().
2849 Suggested by: Markus Mauhart <qwe123@chello.at>.
2851 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2852 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2853 If SHELL is set to CMD.EXE then assume it's batch-mode and
2854 non-unixy. I wrote the code differently from the patch, though,
2855 to make it safer. This also resolves bug #9174.
2857 2004-09-20 Paul D. Smith <psmith@gnu.org>
2859 * expand.c (variable_expand_string): Modify to invoke
2860 patsubst_expand() instead of subst_expand(); the latter didn't
2861 handle suffix patterns correctly.
2862 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2863 was used only from variable_expand_string() and is no longer used
2865 (func_subst): Ditto, on call to subst_expand().
2866 (patsubst_expand): Require the percent pointers to point to the
2867 character after the %, not to the % itself.
2868 * read.c (record_files): New call criteria for patsubst_expand().
2869 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2870 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2872 2004-09-19 Paul D. Smith <psmith@gnu.org>
2874 * function.c (subst_expand): Fix a check in by_word: look for a
2875 previous blank if we're beyond the beginning of the string, not
2876 the beginning of the word.
2877 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2879 2004-05-16 Paul D. Smith <psmith@gnu.org>
2881 * remake.c (update_goal_chain): Change the argument specifying
2882 whether we're rebuilding makefiles to be a global variable,
2883 REBUILDING_MAKEFILES.
2884 (complain): Extract the code that complains about no rules to make
2885 a target into a separate function.
2886 (update_file_1): If we tried to rebuild a file during the makefile
2887 rebuild phase and it was dontcare, then no message was printed.
2888 If we then try to build the same file during the normal build,
2889 print a message this time.
2890 (remake_file): Don't complain about un-remake-able files when
2891 we're rebuilding makefiles.
2893 2004-05-11 Paul D. Smith <psmith@gnu.org>
2895 * job.c (construct_command_argv_internal): OS/2 patches from
2896 Andreas Buening <andreas.buening@nexgo.de>.
2898 2004-05-10 Paul D. Smith <psmith@gnu.org>
2900 * remake.c (update_file): Don't walk the double-colon chain unless
2901 this is a double-colon rule. Fix suggested by Boris Kolpackov
2902 <boris@kolpackov.net>.
2904 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2905 * readme.vms: New section describing OpenVMS support and issues.
2906 * default.c (default_variables): Add support for IA64.
2907 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2908 without some privilege aborts make with the error
2909 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2910 pressing Ctrl+Y and the input device is no terminal. The change
2911 catches this error and just continues.
2913 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2915 2004-04-25 Paul D. Smith <psmith@gnu.org>
2917 * commands.c (set_file_variables): Set $< properly in the face of
2918 order-only prerequisites.
2919 Patch from Boris Kolpackov <boris@kolpackov.net>
2921 2004-04-21 Bob Byrnes <byrnes@curl.com>
2923 * main.c (main): Notice failures to remake makefiles.
2925 2004-03-28 Paul D. Smith <psmith@gnu.org>
2927 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2929 * job.c: No default shell for RISC OS.
2930 (load_too_high): Hard-code the return to 1.
2931 (construct_command_argv_internal): No sh_chars or sh_cmds.
2932 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2934 2004-03-20 Paul D. Smith <psmith@gnu.org>
2936 * variable.c (do_variable_definition): Don't append from the
2937 global set if a previous non-appending target-specific variable
2938 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2941 * expand.c (reference_variable): Don't give up on variables with
2942 no value that have the target-specific append flag set: they might
2943 have a value after all. Reported by Oliver Schmidt
2944 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2945 <nikulin@dx1cmd.inp.nsk.su>.
2947 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2948 refer to absolute pathnames in directories that don't exist: some
2949 portion of the makefile could create those directories before we
2950 match the pattern. Fixes bugs #775 and #108.
2952 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2954 * main.c (main): Free makefile_mtimes if we have any.
2955 * README.W32.template: Update documentation for the current status
2956 of the MS-Windows port.
2957 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2958 environment variable is sometimes already defined which causes the
2960 * main.c (debug_signal_handler): Only define this function if
2961 SIGUSR1 is available.
2963 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2965 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2966 * README.OS2.template: Documentation updates.
2967 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2968 link line for safety.
2969 * maintMakefile (build.sh.in): Remove an extraneous ")".
2970 * job.c (child_execute_job): Close saved FDs.
2971 * job.c (exec_command) [OS/2]: exec_command(): If the command
2972 can't be exec'ed and if the shell is not Unix-sh, then try again
2973 with argv = { "cmd", "/c", ... }. Normally, this code is never
2974 reached for the cmd shell unless the command really doesn't exist.
2975 (construct_command_argv_internal) [OS/2]: The code for cmd
2976 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2977 The CMD builtin commands are case insensitive so use strcasecmp().
2979 2004-03-19 Paul D. Smith <psmith@gnu.org>
2981 * read.c (do_define): Re-order line counter increment so the count
2982 is accurate (we were losing one line per define). Reported by
2983 Dave Yost <Dave@Yost.com>.
2985 2004-03-06 Paul D. Smith <psmith@gnu.org>
2987 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2989 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2990 * misc.c (message,error,fatal): Ditto.
2991 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2992 * config.h.W32.template: Ditto.
2993 * config.h-vms.template: Ditto.
2994 * config.ami.template: Ditto.
2996 2004-03-04 Paul D. Smith <psmith@gnu.org>
2998 * README.template: Add a note about broken /bin/sh on SunOS
2999 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3001 * misc.c (message, error, fatal): Don't use "..." if we're using
3002 varargs. ansi2knr should handle this but it doesn't work: it
3003 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3004 done. On many systems (SunOS for example) va_dcl is a #define.
3005 So, force the use of the non-"..." version on pre-ANSI compilers.
3007 * maintMakefile (sign-dist): Create some rules to help automate
3008 the new GNU ftp upload method.
3010 2004-02-24 Paul D. Smith <psmith@gnu.org>
3012 * config.h.W32.template: Add HAVE_STDARG_H
3013 * config.h-vms.template: Ditto.
3014 * config.ami.template: Ditto.
3016 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3018 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3019 * build_w32.bat: Remove extra "+".
3021 2004-02-23 Paul D. Smith <psmith@gnu.org>
3023 * make.h: Create an UNUSED macro to mark unused parameters.
3024 * (many): Clean up warnings by applying UNUSED, fixing
3025 signed/unsigned incompatibilities, etc.
3027 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3029 * filedef.h: Name the command_state enumeration.
3030 * file.c (set_command_state): Use the enumeration in the function
3033 * configure.in: Explicitly set SET_MAKE to empty, to disable
3034 MAKE=make even when no make already exists. Fix bug #3823.
3036 2004-02-22 Paul D. Smith <psmith@gnu.org>
3038 * maintMakefile: Perl script to clean up all non-CVS files. Use
3039 it on all the subdirectories for the cvs-clean target.
3041 * main.c (decode_switches): Require non-empty strings for all our
3042 string command-line options. Fixes Debian bug # 164165.
3044 * configure.in: Check for stdarg.h and varargs.h.
3045 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3046 for printing messages.
3047 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3052 A number of patches for OS/2 support from Andreas Buening
3053 <andreas.buening@nexgo.de>:
3055 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3056 disable the SIGCHLD handler.
3057 (reap_children) [OS/2]: Remove special handling of job_rfd.
3058 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3059 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3060 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3061 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3062 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3065 2004-02-21 Paul D. Smith <psmith@gnu.org>
3067 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3068 <mail@kristov.de> reports that if process_begin() fails we don't
3069 handle the error condition correctly in all cases.
3070 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3071 to have a newline on the message.
3073 * job.c (construct_command_argv_internal): Add "test" to UNIX
3074 sh_cmds[]. Fixes Savannah bug # 7606.
3076 2004-02-04 Paul D. Smith <psmith@gnu.org>
3078 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3079 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3080 Hartmut Becker <Hartmut.Becker@hp.com>.
3082 2004-01-21 Paul D. Smith <psmith@gnu.org>
3084 * job.c (load_too_high): Implement an algorithm to control the
3085 "thundering herd" problem when using -l to control job creation
3086 via the load average. The system only recomputes the load once a
3087 second but we can start many jobs in a second. To solve this we
3088 keep track of the number of jobs started in the last second and
3089 apply a weight to try to guess what a correct load would be.
3090 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3091 Also fixes bug #4693.
3092 (reap_children): Decrease the job count for this second.
3093 (start_job_command): Increase the job count for this second.
3095 * read.c (conditional_line): Expand the text after ifn?def before
3096 checking to see if it's a single word. Fixes bug #7257.
3098 2004-01-09 Paul D. Smith <psmith@gnu.org>
3100 * file.c (print_file): Recurse to print all targets in
3101 double-colon rules. Fixes bug #4518, reported (with patch) by
3102 Andrew Chatham <chatham@google.com>.
3104 2004-01-07 Paul D. Smith <psmith@gnu.org>
3106 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3107 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3108 AC_FUNC_SETVBUF_REVERSED.
3110 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3111 (MAKE Variable): Fix Savannah bug #4898.
3113 * job.c (construct_command_argv_internal): Add "!" to the list of
3114 shell escape chars. POSIX sh allows it to appear before a
3115 command, to negate the exit code. Fixes bug #6404.
3117 * implicit.c (pattern_search): When matching an implicit rule,
3118 remember which dependencies have the ignore_mtime flag set.
3119 Original fix provided in Savannah patch #2349, by Benoit
3120 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3122 2003-11-22 Paul D. Smith <psmith@gnu.org>
3124 * README.W32.template (Outputs): Clarification on -j with
3125 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3128 2003-11-02 Paul D. Smith <psmith@gnu.org>
3130 * function.c (func_if): Strip all the trailing whitespace from the
3131 condition, then don't expand it. Fixed bug # 5798.
3133 * expand.c (recursively_expand_for_file): If we're expanding a
3134 variable with no file context, then use the variable's context.
3137 2003-10-21 Paul D. Smith <psmith@gnu.org>
3139 * main.c (log_working_directory): Add newlines to printf()s.
3141 * README.cvs: Add a note to ignore warnings during autoreconf.
3143 * maintMakefile (po_repo): Set a new URL for PO file updates.
3144 (get-config/config.guess get-config/config.sub): Get these files
3145 from the Savannah config project instead of ftp.gnu.org.
3147 2003-10-05 Paul Eggert <eggert@twinsun.com>
3149 * main.c (main): Avoid potential subscript error if environ has
3152 2003-08-22 Paul D. Smith <psmith@gnu.org>
3154 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3155 systems which don't yet implement the C89 standard :-/.
3157 2003-07-18 Paul D. Smith <psmith@gnu.org>
3159 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3160 [WINDOWS32]: Initialize hash.
3162 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3164 * dir.c (read_dirstream): Provide a workaround for broken versions of
3165 the MinGW dirent structure.
3167 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3169 * w32/include/dirent.h: Add __MINGW32__ filter.
3171 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3173 * make.h: Add global declaration of *make_host.
3174 * main.c (print_usage): Remove local declaration of *make_host.
3175 (print_version): Display "This program built for ..." after Copyright
3178 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3180 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3181 execution of "makeinfo --html make.texi".
3183 2003-04-30 Paul D. Smith <psmith@gnu.org>
3185 * build.template: Make some changes to maybe allow this script to
3186 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3188 * README.OS2.template: New file for OS/2 support. Original
3189 contributed by Andreas Buening.
3190 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3193 2003-04-19 Paul D. Smith <psmith@gnu.org>
3195 Fix bug #1405: allow a target to match multiple pattern-specific
3198 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3199 variable.c, where they've always belonged.
3200 * rule.h: Move the prototypes and struct pattern_var as well.
3201 * variable.c (initialize_file_variables): Invoke
3202 lookup_pattern_var() in a loop, until no more matches are found.
3203 If a match is found, create a new variable set for the target's
3204 pattern variables. Then merge the contents of each matching
3205 pattern variable set into the target's pattern variable set.
3206 (lookup_pattern_var): Change this function to be usable
3207 in a loop. It takes a starting position: if NULL, start at the
3208 beginning; if non-NULL, start with the pattern variable after that
3209 position, and return the next matching pattern.
3210 (create_pattern_var): Create a unique instance of
3211 pattern-specific variables for every definition in the makefile.
3212 Don't combine the same pattern together. This allows us to
3213 process the variable handling properly even when the same pattern
3214 is used multiple times.
3215 (parse_variable_definition): New function: break out the parsing
3216 of a variable definition line from try_variable_definition.
3217 (try_variable_definition): Call parse_variable_definition to
3219 (print_variable_data_base): Print out pattern-specific variables.
3220 * variable.h (struct variable): Remember when a variable is
3221 conditional. Also remember its flavor.
3222 (struct pattern_var): Instead of keeping a variable set, we just
3223 keep a single variable for each pattern.
3224 * read.c (record_target_var): Each pattern variable contains only a
3225 single variable, not a set, so create it properly.
3226 * doc/make.texi (Pattern-specific): Document the new behavior.
3228 2003-04-17 Paul D. Smith <psmith@gnu.org>
3230 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3231 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3232 file/directory naming rules for VMS so I can't tell whether this
3235 2003-04-09 Paul D. Smith <psmith@gnu.org>
3237 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3238 DOS-style pathnames: backslash separators and drive specifiers.
3240 2003-03-28 Paul D. Smith <psmith@gnu.org>
3242 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3243 the intermediate flag on all targets. Fixes bug #2515.
3245 2003-03-24 Paul D. Smith <psmith@gnu.org>
3247 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3248 Upgrade to autoconf 2.57 and automake 1.7.3.
3250 * job.c: More OS/2 changes from Andreas Buening.
3252 * file.c (print_file): Fix variable initialization.
3255 * remake.c (notice_finished_file):
3257 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3258 some calls (like readdir()) return NULL in valid situations
3259 without resetting errno. Fixes bug #2846.
3261 2003-02-25 Paul D. Smith <psmith@gnu.org>
3263 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3265 * job.c (_is_unixy_shell) [OS/2]: New function.
3266 Set default shell to /bin/sh.
3267 (reap_children): Close the job_rfd pipe here since we don't use a
3269 (set_child_handler_action_flags): define this to empty on OS/2.
3270 (start_job_command): Close the jobserver pipe and use
3271 child_execute_job() instead of fork/exec.
3272 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3273 rather than exec'ing, then reconfigure stdin/stdout.
3274 (exec_command): Rewrite to use spawn instead of exec. Return the
3277 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3278 in DOS. Handle the TEMP environment variable as in DOS. Don't
3279 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3280 use -j in DOS mode. Use child_execute_job() instead of
3283 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3286 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3287 prototypes that return values.
3289 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3291 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3292 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3294 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3297 2003-02-24 Paul D. Smith <psmith@gnu.org>
3299 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3300 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3301 (child_execute_job) [VMS]: Handle error status properly.
3302 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3304 * function.c (func_shell): Use EINTRLOOP() while reading from the
3305 subshell pipe (Fixes bug #2502).
3306 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3308 * main.c (main): Ditto.
3310 2003-01-30 Paul D. Smith <psmith@gnu.org>
3312 * read.c (eval): eval() was not fully reentrant, because the
3313 collapsed buffer was static. Change it to be an automatic
3314 variable so that eval() can be invoked recursively.
3316 (eval): Apply patch # 1022: fix memory reference error on long
3317 target-specific variable lines.
3318 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3320 * function.c (check_numeric): Combine the is_numeric() function
3321 into this function, since it's only called from one place.
3322 Constify this function. Have it print the incorrect string in the
3323 error message. Fixes bug #2407.
3324 (strip_whitespace): Constify.
3325 (func_if): Constify.
3326 * expand.c (expand_argument): Constify.
3328 2003-01-29 Paul D. Smith <psmith@gnu.org>
3330 Fix bug # 2169, also reported by other people on various systems.
3332 * make.h: Some systems, such as Solaris and PTX, do not fully
3333 implement POSIX-compliant SA_RESTART functionality; important
3334 system calls like stat() and readdir() can still fail with EINTR
3335 even if SA_RESTART has been set on the signal handler. So,
3336 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3337 EINTR for system calls which return -1 or 0 (NULL), respectively,
3339 Also, remove the old atomic_stat()/atomic_readdir() and
3340 HAVE_BROKEN_RESTART handling.
3342 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3344 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3345 * remake.c (touch_file): Ditto.
3347 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3348 * read.c (construct_include_path): Ditto.
3349 * remake.c (name_mtime): Ditto.
3350 * vpath.c (selective_vpath_search): Ditto.
3351 * dir.c (find_directory): Ditto.
3352 (local_stat): Ditto.
3353 (find_directory): Use ENULLLOOP() to wrap opendir().
3354 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3356 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3357 atomic_readdir() handling.
3359 2003-01-22 Paul D. Smith <psmith@gnu.org>
3361 * function.c (func_call): Fix Bug #1744. If we're inside a
3362 recursive invocation of $(call ...), mask any of the outer
3363 invocation's arguments that aren't used by this one, so that this
3364 invocation doesn't "inherit" them accidentally.
3366 2002-12-05 Paul D. Smith <psmith@gnu.org>
3368 * function.c (subst_expand): Valery Khamenia reported a
3369 pathological performance hit when doing substitutions on very
3370 large values with lots of words: turns out we were invoking
3371 strlen() a ridiculous number of times. Instead of having each
3372 call to sindex() call strlen() again, keep track of how much of
3373 the text we've seen and pass the length to sindex().
3375 2002-11-19 Paul D. Smith <psmith@gnu.org>
3377 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3380 2002-11-16 Paul D. Smith <psmith@gnu.org>
3382 * NMakefile.template (OBJS): Add hash.c object file.
3383 * SMakefile.template (srcs): Ditto.
3384 * Makefile.ami (objs): Ditto.
3385 * build_w32.bat: Ditto.
3387 * Makefile.DOS.template: Remove extra dependencies.
3389 2002-10-25 Paul D. Smith <psmith@gnu.org>
3391 * expand.c (install_variable_buffer): New function. Install a new
3392 variable_buffer context and return the previous one.
3393 (restore_variable_buffer): New function. Free the current
3394 variable_buffer context and put a previously saved one back.
3395 * variable.h: Prototypes for {install,restore}_variable_buffer.
3396 * function.c (func_eval): Push a new variable_buffer context
3397 before we eval, then restore the old one when we're done.
3400 * read.c (install_conditionals): New function. Install a new
3401 conditional context and return the previous one.
3402 (restore_conditionals): New function. Free the current
3403 conditional context and put a previously saved one back.
3404 (eval): Use the {install,restore}_conditionals for "include"
3406 (eval_buffer): Use {install,restore}_conditionals to preserve the
3407 present conditional state before we evaluate the buffer.
3410 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3412 (Recursion): Add a variable index entry for CURDIR.
3414 * README.cvs: Update to appropriate versions.
3415 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3416 don't need to copy loadavg.c: automake is smart enough to create
3417 it for me. Still have a bug in automake related to ansi2knr tho.
3419 2002-10-14 Paul D. Smith <psmith@gnu.org>
3421 * remake.c (notice_finished_file): Only touch targets if they have
3422 at least one command (as per POSIX). Resolve Bug #1418.
3424 * *.c: Convert to using ANSI C-style function definitions.
3425 * Makefile.am: Enable the ansi2knr feature of automake.
3426 * configure.in: ditto.
3428 2002-10-13 Paul D. Smith <psmith@gnu.org>
3430 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3431 for automatic variable values like $^, etc. In the case of very
3432 large lists of prerequisites this causes problems. Instead reuse
3433 a static buffer (resizeable) for each variable.
3435 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3436 target-specific variable definitions. Check for it and set an
3438 (record_target_var): Set the export field to v_export if the
3439 "exported" flag is set.
3440 * doc/make.texi (Target-specific): Document the ability to use
3443 * doc/make.texi: Change the name of the section on automatic
3444 variables from "Automatic" to "Automatic Variables". Added text
3445 clarifying the scope of automatic variables.
3447 2002-10-04 Paul D. Smith <psmith@gnu.org>
3449 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3451 (record_files): Ditto.
3453 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3454 the search for the '=' to only within the enclosing parens.
3456 2002-10-03 Paul D. Smith <psmith@gnu.org>
3458 Version 3.80 released.
3460 * dir.c: Change hash functions to use K&R function definition style.
3461 * function.c: Ditto.
3463 * variable.c: Ditto.
3465 Update to automake 1.7.
3467 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3468 (pdf): Remove this target as automake now provides one.
3470 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3472 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3474 * makefile.com: Updates for GNU make 3.80.
3475 * makefile.vms: Ditto.
3477 2002-09-23 Paul D. Smith <psmith@gnu.org>
3479 * read.c (enum make_word_type): Remove w_comment.
3480 (get_next_mword): Don't treat comment characters as special; where
3481 this function is used we will never see a comment (it's stripped
3482 before we get here) and treating comments specially means that
3483 targets like "foo\#bar" aren't handled properly.
3485 2002-09-18 Paul D. Smith <psmith@gnu.org>
3487 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3489 * read.c (eval): Expansion of arguments to export/unexport was
3490 ignoring all arguments after the first one. Change the algorithm
3491 to expand the whole line once, then parse the results.
3493 2002-09-17 Paul D. Smith <psmith@gnu.org>
3495 Fix Bug #940 (plus another bug I found while looking at this):
3497 * read.c (record_target_var): enter_file() will add a new entry if
3498 it's a double-colon target: we don't want to do that in this
3499 situation. Invoke lookup_file() and only enter_file() if it does
3500 not already exist. If the file we get back is a double-colon then
3501 add this variable to the "root" double-colon target.
3503 * variable.c (initialize_file_variables): If this file is a
3504 double-colon target but is not the "root" target, then initialize
3505 the root and make the root's variable list the parent of our
3508 2002-09-13 Paul D. Smith <psmith@gnu.org>
3510 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3512 * hash.c (round_up_2): Get rid of a warning.
3514 2002-09-12 Paul D. Smith <psmith@gnu.org>
3516 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3517 so it doesn't complain about getloadavg.c.
3519 * commands.c (set_file_variables): Make sure we always alloca() at
3520 least 1 character for the value of $? (for '\0').
3522 2002-09-11 Paul D. Smith <psmith@gnu.org>
3524 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3525 macro to use RESULT instead of the incorrect _RESULT_.
3527 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3528 and atomic_readdir(). We need to #include dirent.h to get this to
3530 * misc.c (atomic_readdir): Fix typos.
3532 2002-09-10 Paul D. Smith <psmith@gnu.org>
3534 * read.c (eval): Expand variable lists given to export and
3535 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3536 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3538 * doc/make.texi (Variables/Recursion): Document this.
3539 (Conditional Syntax): And here.
3541 2002-09-09 Paul D. Smith <psmith@gnu.org>
3543 * configure.in: Check for memmove().
3545 2002-09-07 Paul D. Smith <psmith@gnu.org>
3547 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3548 Michael Sterrett <msterret@coat.com> reports that while it has
3549 SA_RESTART, it does not work properly.
3551 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3552 that invokes stat() and loops to do it again if it returns EINTR.
3553 (atomic_readdir): Ditto, with readdir().
3555 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3556 and readdir() to atomic_stat() and atomic_readdir().
3558 2002-09-04 Paul D. Smith <psmith@gnu.org>
3560 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3561 reports that GNU make sometimes doesn't recognize that targets can
3562 be made, when directories can be created as prerequisites. He
3563 reports that changing the order of predicates in the DEP->changed
3564 flag test so that lookup_file() is always performed, solves this
3567 2002-08-08 Paul D. Smith <psmith@gnu.org>
3569 * configure.in: Require a newer version of gettext.
3571 * misc.c (perror_with_name): Translate the format string (for
3572 right-to-left language support).
3573 (pfatal_with_name): Ditto.
3575 * main.c: Create a static array of strings to store the usage
3576 text. This is done to facilitate translations.
3577 (struct command_switch): Remove argdesc and description fields.
3578 (switches): Remove values for obsolete fields.
3579 (print_usage): Print each element of the usage array.
3581 * hash.c: Change function definitions to be K&R style.
3583 2002-08-02 Paul D. Smith <psmith@gnu.org>
3585 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3586 this one because it's too hard to get right. We'll look at it for
3588 * main.c (main): Don't create the .TARGETS variable.
3589 * variable.c (handle_special_var): Don't handle .TARGETS.
3591 2002-08-01 Paul D. Smith <psmith@gnu.org>
3593 * main.c (switches): Add a new option, -B (--always-make). If
3594 specified, make will rebuild all targets that it encounters even
3595 if they don't appear to be out of date.
3596 (always_make_flag): New flag.
3597 * make.h: Extern always_make_flag.
3598 * remake.c (update_file_1): Check always_make_flag; if it's set we
3599 will always rebuild any target we can, even if none of its
3600 prerequisites are newer.
3603 * doc/make.texi (Shell Function): Make it clear that make
3604 variables marked as "export" are not passed to instances of the
3607 Add new introspection variable .VARIABLES and .TARGETS.
3609 * variable.c (handle_special_var): New function. If the variable
3610 reference passed in is "special" (.VARIABLES or .TARGETS),
3611 calculate the new value if necessary. .VARIABLES is handled here:
3612 walk through the hash of defined variables and construct a value
3613 which is a list of the names. .TARGETS is handled by
3614 build_target_list().
3615 (lookup_variable): Invoke handle_special_var().
3616 * file.c (build_target_list): Walk through the hask of known files
3617 and construct a list of the names of all the ones marked as
3619 * main.c (main): Initialize them to empty (and as simple variables).
3620 * doc/make.texi (Special Variables): Document them.
3621 * NEWS: Mention them.
3623 * variable.h (struct variable): Add a new flag "exportable" which
3624 is true if the variable name is valid for export.
3625 * variable.c (define_variable_in_set): Set "exportable" when a new
3626 variable is defined.
3627 (target_environment): Use the "exportable" flag instead of
3628 re-checking the name here... an efficiency improvement.
3630 2002-07-31 Paul D. Smith <psmith@gnu.org>
3632 * config.h-vms.template: Updates to build on VMS. Thanks to
3633 Brian_Benning@aksteel.com for helping verify the build.

3646 * variable.c (pop_variable_scope): Remove variable made unused by
3647 new hash infrastructure.
3648 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3649 comparisons as well as name comparisons.
3650 * variable.h: Add a prototype for new hash_init_function_table().
3651 * file.c (lookup_file): Remove variables made unused by new hash
3653 * dir.c (directory_contents_hash_2): Missing return of hash value.
3654 (dir_contents_file_exists_p): Remove variables made unused by new
3655 hash infrastructure.
3658 Installed Greg McGary's integration of the hash functions from the
3659 GNU id-utils package:
3661 2002-07-10 Greg McGary <greg@mcgary.org>
3663 * scripts/functions/filter-out: Add literals to to the
3664 pattern space in order to add complexity, and trigger
3665 use of an internal hash table. Fix documentation strings.
3666 * scripts/targets/INTERMEDIATE: Reverse order of files
3667 passed to expected `rm' command.
3669 2002-07-10 Greg McGary <greg@mcgary.org>

3761 2002-07-10 Paul D. Smith <psmith@gnu.org>
3763 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3764 prerequisite list. A real SysV make will expand the entire
3765 prerequisites list _twice_: we don't do that as it's a big
3766 backward-compatibility problem. We only replace those specific
3769 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3770 references left in the list of prerequisites. Check for .POSIX as
3771 we record targets, so we can disable non-POSIX behavior while
3772 reading makefiles as well as running them.
3773 (eval): Check the prerequisite list to see if we have anything
3774 that looks like a SysV prerequisite variable reference.
3776 2002-07-09 Paul D. Smith <psmith@gnu.org>
3778 * doc/make.texi (Prerequisite Types): Add a new section describing
3779 order-only prerequisites.
3781 * read.c (uniquize_deps): If we have the same file as both a
3782 normal and order-only prereq, get rid of the order-only prereq,
3783 since the normal one supersedes it.
3785 2002-07-08 Paul D. Smith <psmith@gnu.org>
3787 * AUTHORS: Added Greg McGary to the AUTHORS file.
3788 * NEWS: Blurbed order-only prerequisites.
3789 * file.c (print_file): Show order-only deps properly when printing
3792 * maintMakefile: Add "update" targets for wget'ing the latest
3793 versions of various external files. Taken from Makefile.maint in
3796 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3797 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3799 2002-07-07 Paul D. Smith <psmith@gnu.org>
3801 * po/*.po: Remove. We'll use wget to retrieve them at release
3804 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3805 rather than a shell you get an exception. Make sure we look up
3806 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3808 * remake.c (notice_finished_file): Fix handling of -t flag.
3809 Patch provided by Henning Makholm <henning@makholm.net>.
3811 * implicit.c (pattern_search): Some systems apparently run short
3812 of stack space, and using alloca() in this function caused an
3813 overrun. I modified it to use xmalloc() on the two variables
3814 which seemed like they might get large. Fixes Bug #476.
3816 * main.c (print_version): Update copyright notice to conform with
3818 (print_usage): Update help output.
3820 * function.c (func_eval): Create a new make function, $(eval
3821 ...). Expand the arguments, put them into a buffer, then invoke
3822 eval_buffer() on the resulting string.
3823 (func_quote): Create a new function, $(quote VARNAME). Inserts
3824 the value of the variable VARNAME without expanding it any
3827 * read.c (struct ebuffer): Change the linebuffer structure to an
3828 "eval buffer", which can be either a file or a buffer.
3829 (eval_makefile): Move the code in the old read_makefile() which
3830 located a makefile into here: create a struct ebuffer with that
3831 information. Have it invoke the new function eval() with that
3833 (eval_buffer): Create a new function that creates a struct ebuffer
3834 that holds a string buffer instead of a file. Have it invoke
3835 eval() with that ebuffer.
3836 (eval): New function that contains the guts of the old
3837 read_makefile() function: this function parses makefiles. Obtains
3838 data to parse from the provided ebuffer. Some modifications to
3839 make the flow of the function cleaner and clearer. Still could
3840 use some work here...
3841 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3842 contents of the define/endef variable from the ebuffer.
3843 (readstring): Read the next line from a string-style ebuffer.
3844 (readline): Read the next line from an ebuffer. If it's a string
3845 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3848 * dep.h (eval_buffer): Prototype eval_buffer();
3850 * variable.c (do_variable_definition): Make sure that all
3851 non-target-specific variables are registered in the global set.
3852 If we're invoked from an $(eval ...) we might be inside a $(call
3853 ...) or other function which has pushed a variable scope; we still
3854 want to define our variables from evaluated makefile code in the
3857 2002-07-03 Greg McGary <greg@mcgary.org>
3859 * dep.h (struct dep) [ignore_mtime]: New member.
3860 [changed]: convert to a bitfield.
3861 * implicit.c (pattern_search): Zero ignore_mtime.
3862 * main.c (main, handle_non_switch_argument): Likewise.
3863 * rule.c (convert_suffix_rule): Likewise.
3864 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3865 (read_makefile): Parse '|' in prerequisite list.
3866 (uniquize_deps): Consider ignore_mtime when comparing deps.
3867 * remake.c (update_file_1, check_dep): Don't force remake for
3868 dependencies that have d->ignore_mtime.
3869 * commands.c (FILE_LIST_SEPARATOR): New constant.
3870 (set_file_variables): Don't include a
3871 prerequisite in $+, $^ or $? if d->ignore_mtime.
3874 2002-06-18 Paul D. Smith <psmith@gnu.org>
3876 * make.texinfo: Updates for next revision. New date/rev/etc.
3877 Recreate all Info menus. Change license on the manual to the GNU
3878 Free Documentation License. A number of typos.
3879 (Variables Simplify): Don't use "-" before it's defined.
3880 (Automatic Prerequisites): Rewrite the target example to work
3881 properly if the compile fails. Remove incorrect comments about
3882 how "set -e" behaves.
3883 (Text Functions): Move the "word", "wordlist", "words", and
3884 "firstword" functions here, from "File Name Functions".
3885 * make-stds.texi: Update from latest GNU version.
3886 * fdl.texi: (created) Import the latest GNU version.
3888 2002-06-06 Paul D. Smith <psmith@gnu.org>
3890 * variable.c (do_variable_definition): New function: extract the
3891 part of try_variable_definition() that actually sets the value
3892 into a separate function.
3893 (try_variable_definition): Call do_variable_definition() after
3894 parsing the variable definition string.
3895 (define_variable_in_set): Make the name argument const.
3897 * variable.h (enum variable_flavor): Make public.
3898 (do_variable_definition): Create prototype.
3900 * read.c (read_all_makefiles): Create a new built-in variable,
3902 (read_makefile): Add each makefile read in to this variable value.
3904 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3906 * Makefile.DOS.template: Tweak according to changes in the
3907 distribution. Add back the dependencies of *.o files.
3909 * configh.dos.template: Synchronize with config.h.in.
3911 2002-05-09 Paul D. Smith <psmith@gnu.org>
3913 * file.c (file_timestamp_now): Use K&R function declaration.
3915 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3916 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3917 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3918 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3919 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3920 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3921 nlist.n_name is a pointer rather than an array.
3923 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3924 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3925 * configure.in: Use it instead of the old version.
3927 * main.c (main): Prefer setvbuf() to setlinebuf().
3929 2002-05-08 Paul D. Smith <psmith@gnu.org>
3931 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3932 (loadavg_LDADD): Ditto.
3934 2002-04-29 Paul D. Smith <psmith@gnu.org>
3936 * expand.c (recursively_expand_for_file): Rename
3937 recursively_expand() to recursively_expand_for_file() and provide
3938 an extra argument, struct file. If the argument is provided, set
3939 the variable scope to that of the file before expanding.
3940 * variable.h (recursively_expand): Make this a macro that invokes
3941 recursively_expand_for_file() with a NULL file pointer.
3942 * variable.c (target_environment): Call the renamed function and
3943 provide the current file context.
3944 Fixes Debian bug #144306.
3946 2002-04-28 Paul D. Smith <psmith@gnu.org>
3948 Allow $(call ...) user-defined variables to be self-referencing
3949 without throwing an error. Allows implementation of transitive
3950 closures, among other possibly useful things.
3951 Requested by: Philip Guenther <guenther@sendmail.com>
3953 * variable.h (struct variable): Add a new field: exp_count, and
3954 new macros to hold its size and maximum value.
3955 (warn_undefined): Make this a macro.
3956 * variable.c (define_variable_in_set): Initialize it.
3957 * expand.c (recursively_expand): If we detect recursive expansion
3958 of a variable, check the exp_count field. If it's greater than 0
3959 allow the recursion and decrement the count.
3960 (warn_undefined): Remove this (now a macro in variable.h).
3961 * function.c (func_call): Before we expand the user-defined
3962 function, modify its exp_count field to contain the maximum
3963 number of recursive calls we'll allow. After the call, reset it
3966 2002-04-21 Paul D. Smith <psmith@gnu.org>
3968 Modified to use latest autoconf (2.53), automake (1.6.1), and
3969 gettext (0.11.1). We're using gettext's new "external" support,
3970 to avoid including libintl source with GNU make.
3972 * README.cvs: New file. Explain how to build GNU make from CVS.
3974 * configure.in: Modify checking for the system glob library.
3975 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3976 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3977 etc. will manage it correctly). Set an automake conditional
3978 USE_LOCAL_GLOB to decide whether to compile the glob library.
3980 * getloadavg.c (main): Include make.h in the "TEST" program to
3983 * Makefile.am: Remove special rules for loadavg. Replace them
3984 with Automake capabilities for building extra programs.
3986 * signame.c: This file does nothing if the system provide
3987 strsignal(). If not, it implements strsignal(). If the system
3988 doesn't define sys_siglist, then we make our own; otherwise we use
3990 * signame.h: Removed.
3992 * main.c (main): No need to invoke signame_init(). Update copyright.
3994 * ABOUT-NLS: Removed.
3995 * gettext.c: Removed.
3996 * gettext.h: Get a simplified copy from the gettext package.
3998 * i18n/*.po: Moved to po/.
4001 * config/*: Created. Contains package configuration helper files.
4002 * config.guess, config.sub: Moved to config directory.
4004 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4005 Rework to use new-style autoconf features. Use the "external"
4006 mode for gettext. Make the build.sh config file conditional on
4007 whether build.sh.in exists, to avoid autoconf errors.
4008 * acinclude.m4: Removed almost all macros as being obsolete.
4009 Rewrote remaining macros to use AC_DEFINE.
4010 * acconfig.h: Removed.
4012 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4013 conditional to handle customs support. Remove special handling
4016 2002-04-20 Paul D. Smith <psmith@gnu.org>
4018 * function.c (func_call): Don't mark the argument variables $1,
4019 etc. as recursive. They've already been fully expanded so
4020 there's no need to do it again, and doing so strips escaped $'s.
4021 Reported by Sebastian Glita <glseba@yahoo.com>.
4023 * remake.c (notice_finished_file): Walk through double-colon
4024 entries via the prev field, not the next field!
4025 Reported by Greg McGary <greg@mcgary.org>.
4027 * main.c (main): If the user specifies -q and asks for a specific
4028 target which is a makefile, we got an assert. In that case it
4029 turns out we should continue normally instead.
4031 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4033 * i18n/he.po: Installed a new translation.
4035 2002-01-07 Paul D. Smith <psmith@gnu.org>

4041 * i18n/ja.po: Installed an updated translation.
4043 2001-09-06 Paul Eggert <eggert@twinsun.com>
4045 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4046 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4048 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4050 (main): Get rid of any avoidable limit on stack size.

4068 * i18n/ko.po: Installed a new translation.
4070 2001-05-06 Paul D. Smith <psmith@gnu.org>
4072 Modify the EINTR handling.
4074 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4075 the way in which we manage the file descriptor/signal handler race
4076 trap to be more efficient.
4078 2001-05-06 Paul Eggert <eggert@twinsun.com>
4080 Restart almost all system calls that are interrupted, instead
4081 of worrying about EINTR. The lone exception is the read() for
4084 * configure.in (HAVE_SA_RESTART): New macro.
4085 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4086 * main.c (main): Use SA_RESTART instead of the old,
4087 nonstandard SA_INTERRUPT.
4089 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4090 * main.c (bsd_signal): New function or macro,
4091 if the implementation doesn't supply it.
4092 (The bsd_signal function will be in POSIX 1003.1-200x.)
4093 (HANDLESIG): Remove.
4094 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4096 * make.h (EINTR_SET): Remove.
4097 (SA_RESTART): New macro.
4099 * arscan.c (ar_member_touch): Don't worry about EINTR.
4100 * function.c (func_shell): Likewise.
4101 * job.c (reap_children, free_child, new_job): Likewise.
4102 * main.c (main): Likewise.
4103 * remake.c (touch_file, name_mtime): Likewise.
4105 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4106 if fstat failed with errno!=EINTR, the error was ignored.
4108 * job.c (set_child_handler_action_flags): New function.
4109 (new_job): Use it to temporarily clear the SIGCHLD action flags
4110 while reading the token.
4112 2001-05-02 Paul D. Smith <psmith@gnu.org>
4114 * job.c (start_job_command): Don't add define/endef per-line flags
4115 to the top-level flags setting.
4117 2001-04-03 Paul D. Smith <psmith@gnu.org>
4119 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4120 bit on error, so check for odd return values, not non-0 return
4122 (VMS_get_member_info): Calculate the timezone differences correctly.
4123 Reported by John Fowler <jfowler@nyx.net>.
4126 2001-03-14 Paul D. Smith <psmith@gnu.org>
4128 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4129 value before invoking define_variable().
4130 Reported by John Fowler <jfowler@nyx.net>.
4132 2001-02-07 Paul D. Smith <psmith@gnu.org>
4134 * read.c (record_target_var): If we reset the variable due to a
4135 command-line variable setting overriding it, turn off the "append"
4138 2001-01-17 Paul D. Smith <psmith@gnu.org>
4140 * variable.c (lookup_variable) [VMS]: When getting values from the
4141 environment, allocate enough space for the _value_ plus escapes,
4142 not enough space for the name plus escapes :-/.
4143 Reported by John Fowler <jfowler@nyx.net>.
4145 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4146 warnings that make generates, so it doesn't look like an error.
4147 Reported by Karl Berry <karl@gnu.org>.
4150 Fix for PR/2020: Rework appended target-specific variables. I'm
4151 fairly confident this algorithm is finally correct.
4153 * expand.c (allocated_variable_append): Rewrite. Instead of
4154 expanding each appended variable then adding all the expanded
4155 strings together, we append all the unexpanded values going up
4156 through the variable set contexts, then expand the final result.
4157 This behaves just like non-target-specific appended variable
4158 values, while the old way didn't in various corner cases.
4159 (variable_append): New function: recursively append the unexpanded
4160 value of a variable, walking from the outermost variable scope to
4162 * variable.c (lookup_variable): Remove the code that looked up the
4163 variable set list if the found variable was "append". We don't
4165 (lookup_variable_in_set): Make this non-static so we can use it
4167 (try_variable_definition): Use lookup_variable_in_set() rather
4168 than faking out current_variable_set_list by hand (cleanup).
4169 * variable.h: Add a prototype for the now non-static
4170 lookup_variable_in_set().
4172 2000-11-17 Paul D. Smith <psmith@gnu.org>
4174 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4175 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4176 before throwing a fit.
4178 2000-11-17 Paul D. Smith <psmith@gnu.org>
4180 * read.c (readline): CRLF calculations had a hole, if you hit the
4181 buffer grow scenario just right. Reworked the algorithm to avoid
4182 the need for len or lastlen at all. Problem description with
4183 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4185 2000-10-24 Paul D. Smith <psmith@gnu.org>
4187 * gettext.c (SWAP): Declare this with the prototype, otherwise
4188 some systems don't work (non-32-bit? Reported for Cray T3E).
4189 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4191 2000-10-05 Paul D. Smith <psmith@gnu.org>
4193 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4194 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4196 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4198 2000-09-22 Paul D. Smith <psmith@gnu.org>
4200 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4201 parts of the real gettext.h here, and we expect to really include
4202 the real gettext.h later. If we keep this #define, it's ignored.
4204 2000-09-21 Paul D. Smith <psmith@gnu.org>
4206 * main.c (log_working_directory): Rework the text to use complete
4207 sentences, to make life simpler for the translators.
4209 2000-08-29 Paul D. Smith <psmith@gnu.org>
4211 * file.c (remove_intermediates): Print a debug message before we
4212 remove intermediate files, so the user (if she uses -d) knows
4215 2000-08-21 Paul D. Smith <psmith@gnu.org>
4217 * variable.c (try_variable_definition): Change how we handle
4218 target-specific append variable defns: instead of just setting the
4219 value, expand it as an append _but_ only within the current
4220 target's context. Otherwise we lose all but the last value if the
4221 variable is appended more than once within the current target
4222 context. Fixes PR/1831.
4224 2000-08-16 Paul D. Smith <psmith@gnu.org>
4226 * function.c (func_shell): Nul-terminate the buffer before
4227 printing an exec error message (just in case it's not!).
4228 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4230 2000-07-25 Paul D. Smith <psmith@gnu.org>
4232 * job.c (construct_command_argv_internal): Add "~" to the list of
4233 sh_chars[] which disallow optimizing out the shell call.
4235 2000-07-23 Paul Eggert <eggert@twinsun.com>
4237 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4238 supersedes --disable-nsec-timestamps.
4239 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4240 * README: Remove --disable-nsec-timestamps.
4242 * filedef.h (struct file.low_resolution_time): New member.
4243 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4244 * remake.c (update_file_1):
4245 Avoid spurious rebuilds due to low resolution time stamps,
4246 generalizing the earlier code that applied only to archive members.
4247 (f_mtime): Archive members always have low resolution time stamps.
4249 * configure.in: Remove --disable-nsec-timestamps, as this has
4250 been superseded by .LOW_RESOLUTION_TIME.
4252 2000-07-23 Paul Eggert <eggert@twinsun.com>
4254 * configure.in (enable_nsec_timestamps): Renamed from
4255 make_cv_nsec_timestamps, since enable/disable options
4256 shouldn't be cached.
4258 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4259 and Paul Eggert <eggert@twinsun.com>
4261 * file.c (file_timestamp_now):
4262 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4263 so that clock_gettime is not linked unless needed.
4265 * filedef.h (FILE_TIMESTAMP_HI_RES):
4266 Remove definition; "configure" now does this.
4268 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4269 to before high resolution file timestamp check,
4270 since that check now uses uintmax_t.
4271 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4272 high resolution file timestamps.
4273 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4274 so that we don't link in clock_gettime unnecessarily.
4276 2000-07-17 Paul D. Smith <psmith@gnu.org>
4278 * i18n/ja.po: New version of the translation file.
4280 2000-07-07 Paul D. Smith <psmith@gnu.org>
4282 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4283 the offset calculation.
4284 (name_mtime): Replace EINTR test with EINTR_SET macro.
4286 2000-07-07 Paul Eggert <eggert@twinsun.com>
4290 * remake.c (update_file_1):
4291 Avoid spurious rebuilds of archive members due to their
4292 timestamp resolution being only one second.
4293 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4294 the clock's resolution being lower than file timestamps'.
4295 When warning about future timestamps, report only the discrepancy,
4296 not the absolute value of the timestamp and the current time.
4298 * file.c (file_timestamp_now): New arg RESOLUTION.
4299 * filedef.h (file_timestamp_now): Likewise.
4300 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4302 2000-07-05 Paul D. Smith <psmith@gnu.org>
4304 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4305 to listp. Fixes PR/1793.
4307 2000-06-26 Paul Eggert <eggert@twinsun.com>
4309 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4311 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4313 * remake.c (f_mtime): Remove unused var memtime.
4315 2000-06-25 Martin Buchholz <martin@xemacs.org>
4317 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4318 Ran spell-check on make.texinfo.
4320 2000-06-23 Paul D. Smith <psmith@gnu.org>
4322 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4323 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4324 * make.h: Define these macros.
4326 * Version 3.79.1 released.
4328 * configure.in: Add a new option, --disable-nsec-timestamps, to
4329 avoid using sub-second timestamps on systems that support it. It
4330 can lead to problems, e.g. if your makefile relies on "cp -p".
4331 * README.template: Document the issue with "cp -p".
4333 * config.guess, config.sub: Updated.
