19 2011-08-29 Paul Smith <psmith@gnu.org>
21 * expand.c (variable_expand_string): Always allocate a new buffer
22 for a string we're expanding. The string we're working on can get
23 freed while we work on it (for example if it's the value of a
24 variable which modifies itself using an eval operation).
25 See Savannah patch #7534 for the original report by Lubomir Rintel.
27 2011-06-12 Paul Smith <psmith@gnu.org>

45 2011-05-07 Eli Zaretskii <eliz@gnu.org>
47 * job.c (construct_command_argv_internal): Don't assume shellflags
48 is always non-NULL. Escape-protect characters special to the

87 (parse_variable_definition): Parse "!=" shell assignments.
88 * read.c (get_next_mword): Treat "!=" as a varassign word.

96 * strcache.c (various): Increase performance based on comments
97 from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>. Stop looking for
98 a buffer when we find the first one that fits, not the best fit.
99 If there is not enough free space in a buffer move it to a
100 separate list so we don't have to walk it again.
101 * make.h (NDEBUG): Turn off asserts unless maintainer mode is set.

531 if we need to parse a rule that requires the second expansion.
533 2009-10-03 Paul Smith <psmith@gnu.org>
535 * make.h: Include <alloca.h> even on systems where __GNUC__ is
536 defined. Not sure why it was done the other way.
537 Requested by David Boyce <dsb@boyski.com>.
539 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
541 * dep.h (dep): Add the DONTCARE bitfield.
543 * filedef.h (file):Add the NO_DIAG bitfield.
545 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
546 not struct file (a file can be a dependency of many targets,
547 some don't care, some do).
549 * remake.c (update_goal_chain): Propagate DONTCARE from struct
550 dep to struct file before updating the goal and restore it
551 afterwards.
552 (update_file): Don't prune the dependency graph if this target
553 has failed but the diagnostics hasn't been issued.
554 (complain): Scan the file's dependency graph to find the file
555 that caused the failure.
556 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
557 whether to print diagnostics.
559 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
561 2009-09-28 Paul Smith <psmith@gnu.org>
563 * doc/make.texi (Pattern Intro): Move the match algorithm
564 discussion into the "Pattern Match" node.
565 (Pattern Match): Expand on the pattern rule matching algorithm.
567 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
569 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
570 much of the command line on a single pass.
572 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
574 * varible.c (create_pattern_var): Insert variables into the
575 PATTERN_VARS list in the shortest patterns first order.
577 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
578 used to sort the rules.
579 (stemlen_compare): Compare two tryrule elements.
580 (pattern_search): Sort the rules so that they are in the shortest
581 stem first order.
583 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
585 * doc/make.texi (Pattern-specific Variable Values): Describe the
586 new pattern-specific variables application order.
587 (Introduction to Pattern Rules): Describe the new pattern rules
588 search order.
590 * NEWS: Add a note about the new behavior.
592 2009-09-27 Paul Smith <psmith@gnu.org>
594 * doc/make.texi (Double-Colon): Mention that pattern rules with
595 double-colons have a different meaning. Savannah bug #27497.
597 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
599 * configh.dos.template: Remove unconditional definition of
600 SYS_SIGLIST_DECLARED.
601 Include <sys/version.h> because ports of GCC 4.3.0 and later no
602 longer include it, so macros like __DJGPP_MINOR__ are no longer
603 defined automatically.
605 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
606 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
607 instead of using the hardcoded ones.
608 (SUBDIRS): doc subdir added.
609 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
610 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
611 create html formated docs. texi2html may not be ported to DOS.
612 (make.info, make.dvi, make.ps, make.html): Make targets depend on
613 'make.texi'.
614 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
615 -I switch to look in ./ instead of ./doc.
616 (html): Target depend on html-recursive instead of make_1.html.
617 (make_1.html): Removed.
618 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
619 (all-recursive): Allow for more than one subdir in the build
620 process.
621 (mostlyclean-recursive, clean-recursive, distclean-recursive)
622 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
623 (tags-recursive): Allow for more than one subdir in the build
624 process.
625 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
626 targets. Enter into doc/ to produce the targets.
627 (all-am): $(INFO_DEPS) replaced by info.
629 2009-09-26 Paul Smith <psmith@gnu.org>
631 * read.c (record_files): Use free_ns() to free struct nameseq.
632 (eval): Ditto.
634 * rule.c (freerule): Use free_dep_chain().
636 * read.c (record_files): Free FILENAMES chain for implicit rules.
637 (eval): Static pattern targets go into the string cache.
639 * function.c (string_glob): Free NAME in the nameseq chain.
641 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
643 * implicit.c (pattern_search): Terminate early if we haven't
644 found any rules to try (performance improvement).
646 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
648 * implicit.c (pattern_search): Merge three parallel arrays,
649 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
650 of struct TRYRULE. In the old version the latter two arrays
651 had insufficient length.
653 2009-09-24 Paul Smith <psmith@gnu.org>
655 * implicit.c (pattern_search): Add back support for order-only
656 prerequisites for secondary expansion implicit rules, that were
657 accidentally dropped. If we find a "|", enable order-only mode
658 and set IGNORE_MTIME on all deps that are seen afterward.
659 (pattern_search): Fix memory leaks: for intermediate files where
660 we've already set the file variable and pattern variable sets, be
661 sure to either save or free them as appropriate.
663 2009-09-23 Paul Smith <psmith@gnu.org>
665 Rework the way secondary expansion is stored, for efficiency.
666 This changes secondary expansion so that ONLY WHEN we know we have
667 a possibility of needing secondary expansion, do we defer the
668 secondary expansion. This means more parsing the deps but we use
669 a lot less memory (due to the strcache). Also, this fixes
670 Savannah bug #18622.
672 * read.c (eval): Don't parse the dep string here anymore.
673 (record_files): Take the dep argument as an unparsed string. If
674 secondary expansion is enabled AND the prereq string has a '$' in
675 it, then set NEED_2ND_EXPANSION and keep the entire string.
676 Otherwise, parse the dep string here to construct the dep list
677 with the names in the strcache.
679 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
680 duplicate the name string (others are in the strcache).
682 * implicit.c: Remove struct idep and free_idep_chain(): unused.
683 (struct patdeps): New structure to store prereq information.
684 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
685 which prerequisites need expansion, and expand only those.
687 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
688 and enter_prereqs(). split_prereqs() takes a fully-expanded string
689 and splits it into a DEP list, handling order-only prereqs.
690 (enter_prereqs): This function enters a list of DEPs into the file
691 database. If there's a stem defined, expand any pattern chars.
692 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
693 set. Use the above functions.
694 (snap_deps): Only perform second expansion on prereqs that need it,
695 as defined by the NEED_2ND_EXPANSION flag.
696 (print_prereqs): New function to print the prereqs
697 (print_file): Call print_prereqs() rather than print inline.
699 * hash.h (STRING_COMPARE): Take advantage of strcache() by
700 comparing pointers.
701 (STRING_N_COMPARE): Ditto.
702 (ISTRING_COMPARE): Ditto.
704 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
705 (parse_file_seq): Return void*
706 * read.c (parse_file_seq): Return void*.
707 (eval): Invoke macroized version of parse_file_seq()
708 * default.c (set_default_suffixes): Ditto.
709 * file.c (split_prereqs): Ditto.
710 * function.c (string_glob): Ditto.
711 * main.c (main): Ditto.
712 * rule.c (install_pattern_rule): Ditto.
714 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
716 2009-09-16 Paul Smith <psmith@gnu.org>
718 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
719 convert to macros.
720 * dep.h: Create alloc_dep() / free_dep() macros.
722 * implicit.c (pattern_search): Take advantage of the new
723 parse_file_seq() to add the directory prefix to each prereq.
725 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
726 all. Avoid reversing chains. Support adding prefixes.
727 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
728 cached/non-cached results.
729 (eval): Remove multi_glob() & invoke new parse_file_seq().
730 * rule.c (install_pattern_rule): Ditto.
731 * main.c (main): Ditto.
732 * implicit.c (pattern_search): Ditto.
733 * function.c (string_glob): Ditto.
734 * file.c (parse_prereqs): Ditto.
735 * default.c (set_default_suffixes): Ditto.
737 * variable.c (parse_variable_definition): Don't run off the end of
738 the string if it ends in whitespace (found with valgrind).
740 * commands.c (set_file_variables): Keep space for all targets in
741 $? if -B is given (found with valgrind).
743 2009-09-15 Paul Smith <psmith@gnu.org>
745 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
746 (xcalloc): Add new function.
747 * make.h: New declarations.
749 * ar.c (ar_glob_match): New calling method for concat().
750 * main.c (main): Ditto.
751 (decode_env_switches): Ditto.
752 * read.c (eval_makefile): Ditto.
753 (tilde_expand): Ditto.
754 (parse_file_seq): Ditto.
755 * variable.c (target_environment): Ditto.
756 (sync_Path_environment): Ditto.
758 * ar.c (ar_glob_match): Use xcalloc().
759 * dir.c (file_impossible): Ditto.
760 * file.c (enter_file): Ditto.
761 * job.c (new_job): Ditto.
762 * read.c (parse_file_seq): Ditto.
763 * vmsfunctions.c (opendir): Ditto.
765 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
767 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
768 inside the loop that looks up environment for PATH.
770 2009-08-31 Eli Zaretskii <eliz@gnu.org>
772 * function.c (windows32_openpipe): Update envp after calling
773 sync_Path_environment.
775 2009-08-02 Paul Smith <psmith@gnu.org>
777 * remake.c (notice_finished_file): Ensure file->cmds is not null
778 before looping through them. Fixes Savannah bug #21824.
780 * doc/make.texi (Wildcard Examples): Clarify when objects is
781 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
782 (Include): Clarify the behavior of -include.
783 Fixes Savannah bug #18963.
785 2009-08-01 Paul Smith <psmith@gnu.org>
787 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
788 etc. come on the command line. Fixes Savannah bug #27093.
790 * expand.c (expand_argument): If the argument is large enough use
791 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
793 * variable.c (do_variable_definition): Avoid using alloca() to
794 hold values, which can be large. Fixes Savannah bug #23960.
796 * job.c (new_job): Use memmove() instead of strcpy() since both
797 pointers are in the same memory block. Fixes Savannah bug #27148.
798 Patch by Petr Machata.
800 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
802 * job.c (construct_command_argv_internal): Add "ulimit" and
803 "unset" to the sh_cmds for Unixy shells.
805 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
807 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
808 that set make_cv_sys_gnu_glob, so they are also correctly set
809 when the cache has been populated before.
811 2009-07-04 Eli Zaretskii <eliz@gnu.org>
813 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
814 exist, as realpath(3) does where it's supported.
816 2006-07-04 Eli Zaretskii <eliz@gnu.org>
818 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
819 (abspath): Support systems that define HAVE_DOS_PATHS (have
820 drive letters in their file names). Use IS_PATHSEP instead of a
821 literal '/' comparison. Fixes Savannah bug #26886.
823 2009-06-14 Paul Smith <psmith@gnu.org>
825 * remake.c (update_file_1): Remember the original file we marked
826 as updating, so we can clear that flag again. If we find a target
827 via vpath, FILE might change.
828 (check_dep): Ditto. Fixes Savannah bug #13529.
829 Patch by Reid Madsen <reid.madsen@tek.com>.
831 2009-06-13 Paul Smith <psmith@gnu.org>
833 * doc/make.texi (MAKEFILES Variable): Be explicit that files
834 included by MAKEFILES cannot give default goals.
835 * read.c (eval): If set_default is not set, pass the no-default-goal
836 value when we read included makefiles. Fixes Savannah bug #13401.
838 * ar.c (ar_name): Ensure that targets with empty parens aren't
839 considered archive member references: archive members must have a
840 non-empty "member" string. Fixes Savannah bug #18435.
842 * function.c (string_glob): Rely on multi_glob() to determine
843 whether files exist or not. Remove call to file_exists_p() which
844 is not always correct. Fixes Savannah bug #21231.
845 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
846 then only files that really exist will be returned.
847 * dep.h: Add new argument to multi_glob().
848 * rule.c (install_pattern_rule): Ditto.
849 * read.c (eval): Ditto.
850 * main.c (main): Ditto.
851 * implicit.c (pattern_search): Ditto.
852 * file.c (parse_prereqs): Ditto.
853 * default.c (set_default_suffixes): Ditto.
855 2009-06-09 Paul Smith <psmith@gnu.org>
857 * commands.c (set_file_variables): If always_make_flag is set,
858 always add the prereq to $?. Fixes Savannah bug #17825.
860 * remake.c (update_file_1): When rebuilding deps of FILE, also try
861 to rebuild the deps of all the also_make targets for that file.
862 Fixes Savannah bug #19108.
864 * implicit.c (pattern_search): Undo test for is_target, added by
865 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
866 Rule Search Algorithm". Fixes Savannah bug #17752.
868 * main.c (clean_jobserver): Clear the jobserver_fds options and
869 set job_slots to the default when we clean up.
870 (define_makeflags): Return the new MAKEFLAGS value.
871 (main): Reset MAKEFLAGS in the environment when we re-exec.
872 Fixes Savannah bug #18124.
874 2009-06-08 Paul Smith <psmith@gnu.org>
876 * read.c (eval): Collapse continuations post-semicolon on target-
877 specific variables. Fixes Savannah bug #17521.
879 2009-06-07 Paul Smith <psmith@gnu.org>
881 * job.c (reap_children): For older systems without waitpid() (are
882 there any of these left?) run wait(2) inside EINTRLOOP to handle
883 EINTR errors. Fixes Savannah bug #16401.
885 * (various): Debug message cleanup. Fixes Savannah bug #16469.
887 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
889 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
890 not the end, to catch second expansion $(eval ...) defining new
891 target/prereq relationships during snap_deps.
892 Fixes Savannah bug #24622.
894 * read.c (record_files): The second-expansion "f->updating" hack
895 was not completely correct: if assumed that the target with
896 commands always had prerequisites; if one didn't then the ordering
897 was messed up. Fixed for now to use f->updating to decide whether
898 to preserve the last element in the deps list... but this whole
899 area of constructing and reversing the deps list is too confusing
900 and needs to be reworked. Fixes Savannah bug #21198.
902 2009-06-06 Paul Smith <psmith@gnu.org>
904 * hash.c (hash_insert): Remove useless test for NULL.
905 Fixes Savannah bug #21823.
907 * make.h: Move SET_STACK_SIZE determination to make.h.
908 * main.c (main): New global variable, STACK_LIMIT, holds the
909 original stack limit when make was started.
910 * job.c (start_job_command): Reset the stack limit, if we changed it.
911 Fixes Savannah bug #22010.
913 * remake.c (check_dep): Only set the target's state to not-started
914 if it's not already running. Found this while testing -j10 builds
915 of glibc: various targets were being rebuilt multiple times.
916 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
917 bug #15919.
919 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
920 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
921 Bugzilla bug 10246.
923 2009-06-04 Paul Smith <psmith@gnu.org>
925 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
927 * maintMakefile: Modify access of config and gnulib Savannah
928 modules to use GIT instead of CVS.
930 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
931 Fixes Savannah bug #24655.
933 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
934 this can happen during some invocations of $(eval ...) for example.
935 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
937 2009-06-02 Paul Smith <psmith@gnu.org>
939 * configure.in: Check for fileno()
940 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
941 for the makefile file so invocations of $(shell ...) don't inherit it.
942 Fixes Savannah bug #24277.
944 2009-06-01 Paul Smith <psmith@gnu.org>
946 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
947 expansion was handled incorrectly. Rework the default goal
948 handling to save the variable only. Remove default_goal_file and
949 default_goal_name.
950 * read.c (eval): Check default_goal_var, not default_goal_name.
951 * read.c (record_target_var): Don't check default_goal_file here.
953 2009-05-31 Paul Smith <psmith@gnu.org>
955 * main.c (main): Expand the .DEFAULT_GOAL variable before using
956 it, and if the multi_glob() returns nothing (say it expanded to
957 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
959 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
960 $(and ..) to the reference. Fixes Savannah bug #25694.
962 * make.1: Be clear that some recipes will be executed even with -n.
963 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
965 * doc/make.texi (Override Directive): Make more clear how
966 overrides and appends interact.
967 Elucidates part of Savannah bug #26207.
969 * read.c (record_target_var): Don't reset the origin on
970 target-specific variables; try_variable_definition() will handle
971 this correctly. Fixes Savannah bug #26207.
973 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
974 Fixes Savannah bug #25712.
976 * implicit.c (pattern_search): Keep a pointer to the beginning of
977 the filename and save that instead of the constructed pointer.
978 Fixes Savannah bug #26593.
979 Patch by Mark Seaborn <mrs@mythic-beasts.com>
981 2009-05-30 Paul Smith <psmith@gnu.org>
983 * doc/make.texi (Multi-Line): Add a description of the new abilities
984 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
985 "command sequence" vs. "recipe" syntax.
986 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
987 after a define, to create variables with those flavors.
989 2009-05-25 Paul Smith <psmith@gnu.org>
991 Reworked the parser for variable assignments to allow multiple
992 modifiers, and in any order. Also allows variable and
993 prerequisites to be modifier names ('export', 'private', etc.)
995 * NEWS: Add notes about user-visible changes.
997 * read.c (struct vmodifiers): Remember what modifiers were seen.
998 (parse_var_assignment): New function to parse variable assignments.
999 (eval): Call the new function. Handle variable assignments earlier.
1001 * variable.c (parse_variable_definition): Only parse; don't create var.
1002 (assign_variable_definition): Call parse, then create the var.
1004 2009-05-24 Paul Smith <psmith@gnu.org>
1006 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1007 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1009 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1011 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1012 Fixes Savannah bug #25412.
1014 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1015 prototype for xmalloc.
1016 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1017 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1018 Loop over an array of extensions, instead of duplicating the same
1019 code inline. Use SearchPath followed by CreateFile, instead of
1020 the obsolete OpenFile. Fixes Savannah bug #17277.
1021 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1022 to `find_file'. Fixes Savannah bug #25662.
1024 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1026 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1027 Fixes Savannah bug #20495.
1029 2009-02-28 Ralf Wildenhues <address@hidden>
1031 * doc/make.texi (Instead of Execution): Document interaction of
1032 -t with phony targets.
1034 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1036 Introduce a new keyword "private" which applies to target-specific
1037 variables and prevents their values from being inherited.
1039 * variable.h (struct variable): Add private_var flag to each variable.
1040 Add a flag to specify which list entry switches to the parent target.
1041 * variable.c (define_variable_in_set): Initialize private_var flag.
1042 (lookup_variable): Skip private variables in parent contexts.
1043 (initialize_file_variables): Set next_is_parent appropriately.
1044 (print_variable): Show the private_var flag.
1045 * read.c (eval): Recognize the private keyword.

1123 HAVE_DECL_SYS_SIGLIST.
1125 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1126 build does not use child_execute_job.
1128 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1129 export the SHELL environment variable to the child.
1131 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1155 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1156 a more complex value than a simple shell: if it's not a default

1159 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1161 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1162 pathnames, with const strings.
1163 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1168 * make.h: Add a prototype for w32_kill() (change suggested by

1195 2007-09-10 Paul Smith <psmith@gnu.org>
1197 * commands.c (print_commands): Don't print an extra line in the
1198 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1200 * read.c (construct_include_path): Add the full string to the cache; we
1201 were chopping the last char.
1203 * NEWS: Announce the .RECIPEPREFIX special variable.
1204 * variable.c (lookup_special_var): Rename from handle_special_var().
1205 (lookup_variable): Call the new name.

1210 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1211 * main.c (main): Create the .RECIPEPREFIX special variable.
1212 * read.c (eval): Remove the cmd_prefix characters from the command
1213 scripts here, so they're not stored in the commands array at all,
1214 rather than waiting and stripping them out during command construction.
1215 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1217 2007-08-15 Paul Smith <psmith@gnu.org>
1219 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1220 file has had the section info removed, so add some to make.texi

1223 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1225 * remake.c (check_dep): Reset the target state for intermediate
1226 files. They might have been considered before but not updated

1245 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1246 Fixes Savannah bug #20452.
1248 2007-07-04 Paul Smith <psmith@gnu.org>

1262 "Expansion of a deferred"
1263 Fixes Savannah bug #20018.
1265 * expand.c (variable_expand_for_file): Preserve the value of

1269 2007-05-11 Paul Smith <psmith@gnu.org>
1271 * job.c (new_job): Add debug info to specify where make found the
1272 command script it is running to build a target.
1273 Fixes Savannah bug #18617.

1276 Add support for Objective C. Fixes Savannah bug #16389.
1277 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1279 * function.c (func_lastword): Initialize p.
1281 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1282 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1283 Dave Korn <dave.korn@artimi.com>
1285 2007-05-08 Paul Smith <psmith@gnu.org>
1287 Fix Savannah bug #19656:
1289 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1291 * make.h: Change all case-insensitive string compares to use
1292 strcasecmp() (from POSIX). If we don't have that but do have one
1293 of the others, define strcasecmp to be one of those instead. If
1294 we don't have any, declare a prototype for our own version.
1296 * misc.c (strcasecmp): Use this if we can't find any native
1297 case-insensitive string comparison function.
1298 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1299 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1300 strcmpi().
1301 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1302 strcasecmp() instead of stricmp().
1303 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1304 instead of strcmpi().
1305 * acinclude.m4: Remove the strcasecmp() check from here.
1307 2007-03-21 Paul Smith <psmith@gnu.org>
1309 * configure.in: Don't turn on case-insensitive file system support
1310 if --disable-... is given. Fixes Savannah bug #19348.
1312 2007-03-19 Paul Smith <psmith@gnu.org>
1314 * ALL: Use the strcache for all file name strings, or other
1315 strings which we will never free. The goal is to save memory by
1316 avoiding duplicate copies of strings. However, at the moment this
1317 doesn't save much memory in most situations: due to secondary
1318 expansion we actually save prerequisite lists twice (once before
1319 the secondary expansion, and then again after it's been parsed
1320 into individual file names in the dep list). We will resolve this
1321 in a future change, by doing the parsing up-front for targets
1322 where secondary expansion is not set.
1324 Moving things into the strcache also allows us to use const
1325 pointers in many more places.
1327 2007-01-03 Paul Smith <psmith@gnu.org>
1329 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1330 the function, not just the first. Fixes Savannah bug #18680.
1332 2006-11-18 Paul Smith <psmith@gnu.org>
1334 * strcache.c (strcache_add_len): Don't allocate a new buffer
1335 unless the string is not already nil-terminated. Technically this
1336 is a violation of the standard, since we may be passed an array
1337 that is not long enough to test one past. However, in make this
1338 is never true since we only use nil-terminated strings or
1339 sub-strings thereof.
1341 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1343 * main.c: New global cmd_prefix, defaults to '\t'.
1344 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1345 of '\t'.
1347 * dir.c: Constified.
1348 (dir_contents_file_exists_p): Check for an error return from
1349 readdir(), just in case.
1351 * commands.c: Constified.
1352 * default.c: Constified.
1353 * expand.c: Constified.
1354 * function.c: Partial constification.
1355 * variable.c: Partial constification.
1356 * vmsify.c: Constification. Hard to test this but I hope I didn't
1357 screw it up!
1358 * vpath.c: Partial constification.
1359 * w32/pathstuff.c: Partial constification.
1361 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1363 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1364 backslashes and drive letters as absolute.
1366 2006-10-22 Paul Smith <psmith@gnu.org>
1368 * main.c (struct command_switch): Use const and void*.
1370 2006-10-21 Paul Smith <psmith@gnu.org>
1372 * ar.c: Constified.
1373 * arscan.c: Constified.
1375 2006-09-30 Paul Smith <psmith@gnu.org>
1377 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1378 point to lastword since the example was updated.
1379 Fixes Savannah bug #16304.
1380 (Secondary Expansion): Correct example description.
1381 Fixes Savannah bug #16468.
1382 (Makefile Contents): Clarify that comments cannot appear within
1383 variable references or function calls.
1384 Fixes Savannah bug #16577.
1385 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1386 Fixes Savannah bug #17701.
1387 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1388 (Prerequisite Types): Added an example of using order-only
1389 prerequisites. Fixes Savannah bug #17880.
1390 (Rule Syntax): "lise" -> "list"
1391 (Multiple Rules): ... -> @dots{}
1392 (Splitting Lines): ditto.
1394 * remake.c (update_file_1): Prereqs that don't exist should be
1395 considered changed, for the purposes of $?.
1396 Fixes Savannah bug #16051.
1398 * make.1: Remove extraneous "+".
1399 Fixes Savannah bug #16652.
1401 2006-09-06 Paul D. Smith <psmith@gnu.org>

1410 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1411 Normally, it is defined in config.h.
1413 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1414 well.
1416 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1417 sh_chars_sh for Windows platforms that emulate Unix.
1419 2006-05-07 Paul D. Smith <psmith@gnu.org>

1445 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1446 inner-scope variables don't mask outer-scope variables.
1448 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1449 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1450 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1451 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1452 values from memory allocation functions: they return void* and so
1453 don't need to be cast. Also remove (char *) casts of arguments to
1454 xrealloc().
1456 * configure.in: Remove checks for memcpy/memmove/strchr.

1464 * variable.c, vpath.c: Ditto.
1466 * make.h (EXIT_FAILURE): Should be 1, not 0.
1468 2006-04-06 Paul D. Smith <psmith@gnu.org>

1496 2006-03-26 Paul D. Smith <psmith@gnu.org>
1498 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1499 support from automake, as described in the Texinfo manual.
1501 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1503 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1504 with lastslash, since the latter points to filename, not to
1505 target.
1506 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1507 Declare and define sh_chars_sh[].
1509 2006-03-23 Paul D. Smith <psmith@gnu.org>
1511 * configure.in: Look for build.sh.in in $srcdir so it will be
1512 built for remote configurations as well.

1515 Fixes Savannah bug #16166.
1517 * misc.c (log_access): Takes a const char *.

1558 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1559 * main.c (main, handle_non_switch_argument): Ditto.
1560 * remake.c (check_dep): Ditto.
1561 * rule.c (convert_suffix_rule, freerule): Ditto.
1563 2006-03-14 Paul D. Smith <psmith@gnu.org>
1565 * expand.c (variable_append): Instead of appending everything then
1566 expanding the result, we expand (or not, if it's simple) each part
1567 as we add it.
1568 (allocated_variable_append): Don't expand the final result.
1569 Fixes Savannah bug #15913.
1571 2006-03-09 Paul Smith <psmith@gnu.org>
1573 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1574 listed non-existent files as changed. Turns out there's a bug in
1575 the Linux kernel builds which means that this change causes
1576 everything to rebuild every time. We will re-introduce this fix
1577 in the next release, to give them time to fix their build system.
1578 Fixes Savannah bug #16002.
1579 Introduces Savannah bug #16051.
1581 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1582 we *don't* find UNIX "/".
1583 Reported by David Ergo <david.ergo@alterface.com>
1585 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1587 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1588 locator function find_and_set_default_shell if SHELL came from the
1589 command line.
1591 2006-02-20 Paul D. Smith <psmith@gnu.org>
1593 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1594 to be null; don't core in that case.
1596 2006-02-19 Paul D. Smith <psmith@gnu.org>
1598 * commands.c (set_file_variables): Realloc, not malloc, the static
1599 string values to avoid memory leaks.
1601 * expand.c (recursively_expand_for_file): Only set reading_file to
1602 an initialized value.
1604 * implicit.c (pattern_search): We need to make a copy of the stem
1605 if we get it from an intermediate dep, since those get freed.
1607 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1608 begin with ".".
1609 (enter_file) [VMS]: Ditto.
1610 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1612 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1614 * job.c (construct_command_argv_internal): Fix last change.
1616 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1617 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1618 the calls to _beginthreadex.
1620 * expand.c (recursively_expand_for_file): Initialize `save' to
1621 prevent compiler warnings.
1623 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1625 * job.c (construct_command_argv_internal): Don't create a temporary
1626 script/batch file if we are under -n. Call _setmode to switch the
1627 script file stream to text mode.
1629 2006-02-17 Paul D. Smith <psmith@gnu.org>
1631 * variable.c (merge_variable_set_lists): Don't try to merge the
1632 global_setlist. Not only is this useless, but it can lead to
1633 circularities in the linked list, if global_setlist->next in one
1634 list gets set to point to another list which also ends in
1635 global_setlist.
1636 Fixes Savannah bug #15757.
1638 2006-02-15 Paul D. Smith <psmith@gnu.org>
1640 Fix for Savannah bug #106.
1642 * expand.c (expanding_var): Keep track of which variable we're
1643 expanding. If no variable is being expanded, it's the same as
1644 reading_file.
1645 * make.h (expanding_var): Declare it.
1646 * expand.c (recursively_expand_for_file): Set expanding_var to the
1647 current variable we're expanding, unless there's no file info in
1648 it (could happen if it comes from the command line or a default
1649 variable). Restore it before we exit.
1650 * expand.c (variable_expand_string): Use the expanding_var file
1651 info instead of the reading_file info.
1652 * function.c (check_numeric): Ditto.
1653 (func_word): Ditto.
1654 (func_wordlist): Ditto.
1655 (func_error): Ditto.
1656 (expand_builtin_function): Ditto.
1657 (handle_function): Ditto.
1659 2006-02-14 Paul D. Smith <psmith@gnu.org>
1661 * read.c (eval): Even if the included filenames expands to the
1662 empty string we still need to free the allocated buffer.
1664 * implicit.c (pattern_search): If we allocated a variable set for
1665 an impossible file, free it.
1666 * variable.c (free_variable_set): New function.
1667 * variable.h: Declare it.
1669 * read.c (read_all_makefiles): Makefile names are kept in the
1670 strcache, so there's never any need to alloc/free them.
1671 (eval): Ditto.
1673 * main.c (main): Add "archives" to the .FEATURES variable if
1674 archive support is enabled.
1675 * doc/make.texi (Special Variables): Document it.
1677 2006-02-13 Paul D. Smith <psmith@gnu.org>
1679 * implicit.c (pattern_search): Add checking for DOS pathnames to
1680 the pattern rule target LASTSLASH manipulation.
1681 Fixes Savannah bug #11183.
1683 2006-02-11 Paul D. Smith <psmith@gnu.org>
1685 * (ALL FILES): Updated copyright and license notices.
1687 2006-02-10 Paul D. Smith <psmith@gnu.org>
1689 A new internal capability: the string cache is a read-only cache
1690 of strings, with a hash table interface for fast lookup. Nothing
1691 in the cache will ever be freed, so there's no need for reference
1692 counting, etc. This is the beginning of a full solution for
1693 Savannah bug #15182, but for now we only store makefile names here.
1695 * strcache.c: New file. Implement a read-only string cache.
1696 * make.h: Add prototypes for new functions.
1697 * main.c (initialize_global_hash_tables): Initialize the string cache.
1698 (print_data_base): Print string cache stats.
1699 * read.c (eval_makefile): Use the string cache to store makefile
1700 names. Rewrite the string allocation to be sure we free everything.
1702 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1704 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1705 directory time stamp didn't change, except on FAT filesystems.
1706 Suggested by J. David Bryan <jdbryan@acm.org>.
1708 2006-02-09 Paul D. Smith <psmith@gnu.org>
1710 * function.c (func_or): Implement a short-circuiting OR function.
1711 (func_and): Implement a short-circuiting AND function.
1712 (function_table_init): Update the table with the new functions.
1713 * doc/make.texi (Conditional Functions): Changed the "if" section
1714 to one on general conditional functions. Added documentation for
1715 $(and ...) and $(or ...) functions.
1716 * NEWS: Note new $(and ...) and $(or ...) functions.
1718 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1720 * job.h (struct child): Add the dontcare bitfield.
1721 * job.c (new_job): Cache dontcare flag.
1722 * job.c (reap_children): Use cached dontcare flag instead of the
1723 one in struct file. Fixes Savannah bug #15641.
1725 2006-02-06 Paul D. Smith <psmith@gnu.org>
1727 * vpath.c (selective_vpath_search): If the file we find has a
1728 timestamp from -o or -W, use that instead of the real time.
1729 * remake.c (f_mtime): If the mtime is a special token from -o or
1730 -W, don't overwrite it with the real mtime.
1731 Fixes Savannah bug #15341.
1733 Updates from Markus Mauhart <qwe123@chello.at>:
1735 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1736 (process_signal, process_last_err, process_exit_code): Manage
1737 invalid handle values.
1738 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1739 manage invalid handles; remove them.
1740 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1741 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1742 * README.cvs: Updates for building from CVS.
1744 2006-02-05 Paul D. Smith <psmith@gnu.org>
1746 * file.c (enter_file): Keep track of the last double_colon entry,
1747 to avoid walking the list every time we want to add a new one.
1748 Fixes Savannah bug #15533.
1749 * filedef.h (struct file): Add a new LAST pointer.
1751 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1752 the comparison. For 64-bits systems the result of the subtraction
1753 might not fit into an int. Use comparison instead.
1754 Fixes Savannah bug #15534.
1756 * doc/make.texi: Update the chapter on writing commands to reflect
1757 the changes made in 3.81 for backslash/newline and SHELL handling.
1759 2006-02-01 Paul D. Smith <psmith@gnu.org>
1761 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1762 variable st is not used when it's not initialized.
1763 Patch from Eli Zaretskii <eliz@gnu.org>.
1765 2006-01-31 Paul D. Smith <psmith@gnu.org>

1768 Markus Mauhart <qwe123@chello.at>.
1769 * README.cvs: Applied patch #4786 from
1770 Markus Mauhart <qwe123@chello.at>.
1771 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1772 J. Grant <jg@jguk.org>.
1774 * main.c: Update the copyright year in the version output.
1775 * prepare_w32.bat: Remove this file from the distribution.
1777 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1779 * remake.c (update_goal_chain): Set g->changed instead of
1780 incrementing it, as it is only 8-bit wide, and could overflow if
1781 many commands got started in update_file.
1783 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1785 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1786 MAXIMUM_WAIT_OBJECTS.
1787 (process_wait_for_any_private): Change dimension of handles[]
1788 array to MAXIMUM_WAIT_OBJECTS.
1789 (process_used_slots): New function.
1790 (process_register): Don't register more processes than the
1791 available number of slots.
1792 (process_easy): Don't start new processes if all slots are used up.
1794 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1795 are already more children than sub_proc.c can handle, behave as if
1796 the load were too high.
1797 (start_job_command): Fix a typo in error message when process_easy
1798 fails.
1800 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1802 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1803 the shell is not sh.exe.
1805 * job.c (create_batch_file): Renamed from create_batch_filename;
1806 all callers changed. Don't close the temporary file; return its
1807 file descriptor instead. New arg FD allows to return the file
1808 descriptor.
1809 (construct_command_argv_internal): Use _fdopen instead of fopen to
1810 open the batch file.
1812 2006-01-04 Paul D. Smith <psmith@gnu.org>
1814 * readme.vms: Updates for case-insensitive VMS file systems from
1815 Hartmut Becker <Hartmut.Becker@hp.com>.
1816 * dir.c (vms_hash): Ditto.
1817 * vmsify.c (copyto): Ditto.
1818 * vmsfunctions.c (readdir): Ditto.
1820 * make.1: Add a section on the exit codes for make.
1822 * doc/make.texi: A number of minor updates to the documentation.

1827 doesn't exist.
1829 * read.c (eval): Be sure to strip off trailing whitespace from the
1830 prerequisites list properly. Also, initialize all fields in
1831 struct dep when creating a new one.
1833 2005-12-28 Paul D. Smith <psmith@gnu.org>
1835 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1836 disable warnings for MSC.
1837 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1839 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1841 * doc/make.texi (Execution): Add a footnote about changes in
1842 handling of backslash-newline sequences. Mention the differences
1843 on MS-DOS and MS-Windows.
1845 * NEWS: More details about building the MinGW port and a pointer
1846 to README.W32. Fix the section name that describes the new
1847 backward-incompatible processing of backslash-newline sequences.
1848 The special processing of SHELL set to "cmd" is only relevant to
1849 MS-Windows, not MS-DOS.
1851 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1853 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1854 to DWORD, to avoid compiler warnings.
1855 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1856 use %ld in format, to avoid compiler warnings.
1858 * doc/make.texi (Special Targets): Fix a typo.
1859 (Appending): Fix cross-reference to Setting.
1860 (Special Variables, Secondary Expansion, File Name Functions)
1861 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1862 periods after a sentence.
1863 (Execution): Add @: after "e.g.".
1864 (Environment): Fix punctuation.
1865 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1866 (Shell Function, Target-specific): Add @: after "vs."
1868 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1870 * read.c (record_target_var): Initialize variable's export field
1871 with v_default instead of leaving it "initialized" by whatever
1872 garbage happened to be on the heap.
1874 2005-12-12 Paul D. Smith <psmith@gnu.org>
1876 * make.1: Fix some display errors and document all existing options.
1877 Patch by Mike Frysinger <vapier@gentoo.org>.
1879 2005-12-11 Paul D. Smith <psmith@gnu.org>
1881 * implicit.c (pattern_search): If 2nd expansion is not set for
1882 this implicit rule, replace the pattern with the stem directly,
1883 and don't re-expand the variable list. Along with the other
1884 .SECONDEXPANSION changes below, fixes bug #13781.
1886 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1888 * implicit.c (pattern_search): Mark other files that this rule
1889 builds as targets so that they are not treated as intermediates
1890 by the pattern rule search algorithm. Fixes bug #13022.
1892 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1894 * remake.c (notice_finished_file): Propagate the change of
1895 modification time to all the double-colon entries only if
1896 it is the last one to be updated. Fixes bug #14334.
1898 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1900 * function.c (func_flavor): Implement the flavor function which
1901 returns the flavor of a variable.
1902 * doc/make.texi (Functions for Transforming Text): Document it.
1903 * NEWS: Add it to the list of new functions.
1905 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1907 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1908 variable.
1909 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1910 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1912 2005-10-26 Paul Smith <psmith@gnu.org>
1914 * read.c (record_files): Don't set deps flags if there are no deps.
1915 * maintMakefile: We only need to build the templates when we are
1916 creating a distribution, so don't do it for "all".
1918 2005-10-24 Paul D. Smith <psmith@gnu.org>
1920 Make secondary expansion optional: its enabled by declaring the
1921 special target .SECONDEXPANSION.
1923 * NEWS: Update information on second expansion capabilities.
1924 * doc/make.texi (Secondary Expansion): Document the
1925 .SECONDEXPANSION special target and its behavior.

1927 prerequisite list was found in a static pattern rule.
1928 (free_dep_chain): Declare a prototype.
1929 * file.c (parse_prereqs): New function: break out some complexity
1930 from expand_deps().
1931 (expand_deps): If we aren't doing second expansion, replace % with
1932 the stem for static pattern rules. Call the new function.
1933 * filedef.h (parse_prereqs): Declare a prototype.
1934 * implicit.c (pattern_search): Initialize the new staticpattern
1935 field.
1936 * main.c (second_expansion): Declare a global variable to remember
1937 if the special target has been seen. Initialize the new
1938 staticpattern field for prerequisites.
1939 * make.h: Extern for second_expansion.
1940 * misc.c (free_dep_chain): New function: frees a struct dep list.
1941 * read.c (read_all_makefiles): Initialize the staticpattern field.
1942 (eval_makefile): Ditto.
1943 (record_files): Check for the .SECONDEXPANSION target and set
1944 second_expansion global if it's found.
1945 Use the new free_dep_chain() instead of doing it by hand.
1946 Set the staticpattern field for prereqs of static pattern targets.
1948 2005-10-16 Paul D. Smith <psmith@gnu.org>
1950 * main.c (main): Set CURDIR to be a file variable instead of a
1951 default, so that values of CURDIR inherited from the environment
1952 won't override the make value.
1954 2005-09-26 Paul D. Smith <psmith@gnu.org>
1956 * job.c (construct_command_argv_internal): If the line is empty
1957 remember to free the temporary argv strings.
1958 Fixes bug # 14527.
1960 2005-09-16 Paul D. Smith <psmith@gnu.org>
1962 * job.c (start_job_command): The noerror flag is a boolean (single
1963 bit); set it appropriately.
1964 Reported by Mark Eichin <eichin@metacarta.com>
1966 2005-08-29 Paul D. Smith <psmith@gnu.org>
1968 * function.c (func_error): On Windows, output from $(info ...)
1969 seems to come in the wrong order. Try to force it with fflush().
1971 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1973 * read.c (record_files): Move code that sets stem for static
1974 pattern rules out of the if (!two_colon) condition so it is
1975 also executed for two-colon rules. Fixes Savannah bug #13881.
1977 2005-08-08 Paul D. Smith <psmith@gnu.org>
1979 * make.h: Don't test that __STDC__ is non-0. Some compilers
1980 (Windows for example) set it to 0 to denote "ISO C + extensions".
1981 Fixes bug # 13594.
1983 2005-08-07 Paul D. Smith <psmith@gnu.org>
1985 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1986 conditional (slightly different version of a fix from Eli).
1988 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1989 If make is running in parallel without -k and two jobs die in a
1990 row, but not too close to each other, then make will quit without
1991 waiting for the rest of the jobs to die.
1993 * main.c (die): Don't reset err before calling reap_children() the
1994 second time: we still want it to be in the error condition.
1995 * job.c (reap_children): Use a static variable, rather than err,
1996 to control whether or not the error message should be printed.
1998 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2000 * w32/subproc/sub_proc.c: Include signal.h.
2001 (process_pipe_io, process_file_io): Pass a pointer to a local
2002 DWORD variable to GetExitCodeProcess. If the exit code is
2003 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2005 * job.c [WINDOWS32]: Include windows.h.
2006 (main_thread) [WINDOWS32]: New global variable.
2007 (reap_children) [WINDOWS32]: Get the handle for the main thread
2008 and store it in main_thread.
2010 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2011 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2012 doing anything else. When we are done, close the main thread
2013 handle and exit with status 130.
2015 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2017 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2018 pointer to fprintf.
2020 * main.c (find_and_set_default_shell): If found a DOSish shell,
2021 set sh_found and the value of default_shell, and report the
2022 findings in debug mode.
2024 * job.c (construct_command_argv_internal): Check unixy_shell, not
2025 no_default_sh_exe, to decide whether to use Unixy or DOSish
2026 builtin commands.
2028 * README.W32: Update with info about the MinGW build.
2030 * build_w32.bat: Support MinGW.
2032 * w32/subproc/build.bat: Likewise.
2034 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2035 printing DWORD args.
2037 * function.c (windows32_openpipe): Fix format strings for printing
2038 DWORD args.
2040 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2041 'reap_mode'.
2042 (start_job_command): Fix format string for printing the result of
2043 process_easy.
2044 (start_job_command) [WINDOWS32]: Do not define.
2045 (exec_command): Fix format string for printing HANDLE args.
2047 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2048 to avoid compiler warnings.
2049 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2050 (Note: some of these fixes were submitted independently by J. Grant)
2052 2005-07-30 J. Grant <jg@jguk.org>
2054 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2055 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2056 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2058 2005-07-15 Paul Smith <psmith@gnu.org>
2060 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2061 we don't have a POSIX shell, then revert to the old
2062 backslash-newline behavior (where they are stripped).
2063 Fixes bug #13665.
2065 2005-07-08 Paul D. Smith <psmith@gnu.org>
2067 * config.h.W32.template: Reorder to match the standard config.h,
2068 for easier comparisons.
2069 From J. Grant <jg@jguk.org>
2071 * maintMakefile: Remove .dep_segment before overwriting it, in
2072 case it's not writable or noclobber is set.
2073 * expand.c (variable_expand_string): Cast result of pointer
2074 arithmetic to avoid a warning.
2075 * main.c (switches): Add full-fledged final initializer.
2077 2005-07-06 Paul D. Smith <psmith@gnu.org>
2079 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2080 * signame.c (strsignal): If we found _sys_siglist[] or
2081 __sys_siglist[] use those instead of sys_siglist[].
2082 From Albert Chin <china@thewrittenword.com>
2084 2005-07-04 Paul D. Smith <psmith@gnu.org>
2086 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2087 globfree(); set up to use the GNU versions.
2088 From Martin Zinser <zinser@zinser.no-ip.info>
2090 2005-07-03 Paul D. Smith <psmith@gnu.org>
2092 From J. Grant <jg@jguk.org>:
2094 * README.W32.template: Update the Windows and tested MSVC versions.
2095 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2096 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2097 * build_w32.bat: Ditto.
2098 * w32/subproc/build.bat: Ditto.
2100 2005-06-28 Paul D. Smith <psmith@gnu.org>
2102 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2103 declaration was checked but not present.
2105 2005-06-27 Paul D. Smith <psmith@gnu.org>
2107 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2108 to unsigned long. Fixes Savannah bug #13550.
2110 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2111 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2112 Fixes Savannah bug #13551.
2114 2005-06-26 Paul D. Smith <psmith@gnu.org>
2116 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2117 it if ANSI_STRING is not set.
2119 2005-06-25 Paul D. Smith <psmith@gnu.org>
2121 * read.c (eval): If no filenames are passed to any of the
2122 "include" variants, don't print an error.
2123 * doc/make.texi (Include): Document this.
2124 Fixes Savannah bug #1761.
2126 * job.c (construct_command_argv_internal): Sanitize handling of
2127 backslash/newline pairs according to POSIX: that is, keep the
2128 backslash-newline in the command script, but remove a following
2129 TAB character, if present. In the fast path, make sure that the
2130 behavior matches what the shell would do both inside and outside
2131 of quotes. In the slow path, quote the backslash and put a
2132 literal newline in the string.
2133 Fixes Savannah bug #1332.
2134 * doc/make.texi (Execution): Document the new behavior and give
2135 some examples.
2136 * NEWS: Make a note of the new behavior.
2138 * make.h [WINDOWS32]: #include <direct.h>.
2139 Fixes Savannah bug #13478.
2141 * remake.c (name_mtime): If the stat() of a file fails and the -L
2142 option was given and the file is a symlink, take the best mtime of
2143 the symlink we can get as the mtime of the file and don't fail.
2144 Fixes Savannah bug #13280.
2146 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2147 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2148 inside a variable reference. Make this function static as it's
2149 only used here.
2150 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2151 parsing an unexpanded line looking for semicolons.
2152 Fixes Savannah bug #1454.
2153 * misc.c (remove_comments): Move this to read.c and make it static
2154 as it's only used there. Call find_char_unquote() with new arg.
2155 * make.h: Remove prototypes for find_char_unquote() and
2156 remove_comments() since they're static now.
2158 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2159 its export flag and obtain its value. When we need to re-exec,
2160 increment the value and add it into the environment.
2161 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2162 * NEWS: Mention MAKE_RESTARTS.
2163 * main.c (always_make_set): New variable. Change the -B option to
2164 set this one instead.
2165 (main): When checking makefiles, only set always_make_flag if
2166 always_make_set is set AND the restarts flag is 0. When building
2167 normal targets, set it IFF always_make_set is set.
2168 (main): Avoid infinite recursion with -W, too: only set what-if
2169 files to NEW before we check makefiles if we've never restarted
2170 before. If we have restarted, set what-if files to NEW _after_ we
2171 check makefiles.
2172 Fixes Savannah bug #7566:
2174 2005-06-17 Paul D. Smith <psmith@gnu.org>
2176 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2177 in the prerequisites list.
2179 2005-06-12 Paul D. Smith <psmith@gnu.org>
2181 Fix Savannah bug # 1328.
2183 * configure.in: Check for atexit().
2184 * misc.c (close_stdout): Test stdout to see if writes to it have
2185 failed. If so, be sure to exit with a non-0 error code. Based on
2186 code found in gnulib.
2187 * make.h: Prototype.
2188 * main.c (main): Install close_stdout() with atexit().
2190 2005-06-10 Paul D. Smith <psmith@gnu.org>
2192 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2194 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2195 headers; make vmsWaitForChildren() static; extern vmsify().
2196 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2197 Don't create child_execute_job() here (it's in vmsjobs.c).
2198 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2200 2005-06-09 Paul D. Smith <psmith@gnu.org>
2202 * variable.c (push_new_variable_scope): File variables point
2203 directly to the global_setlist variable. So, inserting a new
2204 scope in front of that has no effect on those variables: they
2205 don't go through current_variable_set_list. If we're pushing a
2206 scope and the current scope is global, push it "the other way" so
2207 that the new setlist is in the global_setlist variable, and
2208 next points to a new setlist with the global variable set.
2209 (pop_variable_scope): Properly undo a push with the new
2210 semantics.
2211 Fixes Savannah bug #11913.
2213 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2215 * job.c (reap_children): Don't die of the command failed but
2216 the dontcare flag is set. Fixes Savannah bug #13216.
2218 * implicit.c (pattern_search): When creating a target from
2219 an implicit rule match, lookup pattern target and set precious
2220 flag in a newly created target. Fixes Savannah bug #13218.
2222 2005-05-13 Paul D. Smith <psmith@gnu.org>
2224 Implement "if... else if... endif" syntax.
2226 * read.c (eval): Push all checks for conditional words ("ifeq",
2227 "else", etc.) down into the conditional_line() function.
2228 (conditional_line): Rework to allow "else if..." clause. New
2229 return value -2 for lines which are not conditionals. The
2230 ignoring flag can now also be 2, which means "already parsed a
2231 true branch". If that value is seen no other branch of this
2232 conditional can be considered true. In the else parsing if there
2233 is extra text after the else, invoke conditional_line()
2234 recursively to see if it's another conditional. If not, it's an
2235 error. If so, raise the conditional value to this level instead
2236 of creating a new conditional nesting level. Special check for
2237 "else" and "endif", which aren't allowed on the "else" line.
2238 * doc/make.texi (Conditional Syntax): Document the new syntax.
2240 2005-05-09 Paul D. Smith <psmith@gnu.org>
2242 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2243 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2244 recurses to the w32 directory, even on non-Windows systems. Use
2245 the method suggested in the automake manual.
2246 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2247 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2249 2005-05-07 Paul D. Smith <psmith@gnu.org>
2251 * main.c (die): If we're dying with a fatal error (not that a
2252 command has failed), write back any leftover tokens before we go.
2254 * job.c (set_child_handler_action_flags): If there are jobs
2255 waiting for the load to go down, set an alarm to go off in 1
2256 second. This allows us to wake up from a potentially long-lasting
2257 read() and start a new job if the load has gone down. Turn it off
2258 after the read.
2259 (job_noop): Dummy signal handler function.
2260 (new_job): Invoke it with the new semantics.
2262 * docs/make.texi: Document secondary expansion. Various cleanups
2263 and random work.
2265 2005-05-03 Paul D. Smith <psmith@gnu.org>
2267 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2268 the targets which are to ultimately be made are called "goals";
2269 see the GNU make manual. Also, MAKECMDGOALS, etc.
2271 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2272 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2273 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2275 2005-05-02 Paul D. Smith <psmith@gnu.org>
2277 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2278 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2279 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2280 functions to vmsjobs.c. #include it into jobs.c.
2282 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2283 jobserver tokens. I found that this happens when an exported
2284 recursive variable contains a $(shell ...) function reference: in
2285 this situation we could "forget" to write back a token.
2287 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2288 we have. It's not reliable to depend on the number of children in
2289 our linked list so keep a separate count.
2290 (new_job): Check jobserver_tokens rather than children &&
2291 waiting_jobs. Increment jobserver_tokens when we get one.
2292 (free_child): If jobserver_tokens is 0, internal error. If it's
2293 >1, write a token back to the jobserver pipe (we don't write a
2294 token for the "free" job). Decrement jobserver_tokens.
2296 * main.c: Add variable master_job_slots.
2297 (main): Set it to hold the number of jobs requested if we're the
2298 master process, when using the jobserver.
2299 (die): Sanity checks: first test jobserver_tokens to make sure
2300 this process isn't holding any tokens we didn't write back.
2301 Second, if master_job_slots is set count the tokens left in the
2302 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2304 2005-04-24 Paul D. Smith <psmith@gnu.org>
2306 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2307 with -l# can lose jobserver tokens, because waiting jobs are not
2308 consulted properly when checking for the "free" token.
2310 * job.c (free_child): Count waiting_jobs as having tokens.
2311 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2312 handle jobs waiting for the load to drop.
2314 2005-04-23 Paul D. Smith <psmith@gnu.org>
2316 * main.c (main): Be careful to not core if a variable setting in
2317 the environment doesn't contain an '='. This is illegal but can
2318 happen in broken setups.
2319 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2321 2005-04-12 Paul D. Smith <psmith@gnu.org>
2323 The second expansion feature causes significant slowdown. Timing
2324 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2325 read the makefile before the feature, to 11+s to do the same
2326 operations after the feature. Additionally, memory usage
2327 increased drastically. To fix this I added some intelligence that
2328 avoids the overhead of the second expansion unless it's required.
2330 * dep.h: Add a new boolean field, need_2nd_expansion.
2332 * read.c (eval): When creating the struct dep for the target,
2333 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2334 (record_files): If there's a "%" in a static pattern rule, it gets
2335 converted to "$*" so set need_2nd_expansion to 1.
2337 * file.c (expand_deps): Rework to be more efficient. Only perform
2338 initialize_file_variables(), set_file_variables(), and
2339 variable_expand_for_file() if the need_2nd_expansion is set.
2341 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2342 (pattern_search): Ditto.
2343 * main.c (handle_non_switch_argument): Ditto.
2344 (main): Ditto.
2345 * read.c (read_all_makefiles): Ditto.
2346 (eval_makefile): Ditto.
2348 2005-04-07 Paul D. Smith <psmith@gnu.org>
2350 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2351 * variable.c (sync_Path_environment): Ditto.
2352 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2354 * main.c (main): Define the .FEATURES variable.
2355 * NEWS: Announce .FEATURES.
2356 * doc/make.texi (Special Variables): Document .FEATURES.
2358 * remake.c (check_dep): If a file is .PHONY, update it even if
2359 it's marked intermediate. Fixes Savannah bug #12331.
2361 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2363 * file.c (expand_deps): Factor out the second expansion and
2364 prerequisite line parsing logic from snap_deps().
2366 * file.c (snap_deps): Use expand_deps(). Expand and parse
2367 prerequisites of the .SUFFIXES special target first. Fixes
2368 Savannah bug #12320.
2370 2005-03-13 Paul D. Smith <psmith@gnu.org>
2372 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2373 Zaretskii.
2375 2005-03-11 Paul D. Smith <psmith@gnu.org>
2377 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2378 available, not undefined (from Earnie Boyd).
2380 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2382 * implicit.c (pattern_search): Mark an intermediate target as
2383 precious if it happened to be a prerequisite of some (other)
2384 target. Fixes Savannah bug #12267.
2386 2005-03-09 Paul D. Smith <psmith@gnu.org>
2388 * read.c (eval_makefile): Add alloca(0).
2389 (eval_buffer): Ditto.
2391 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2393 * main.c (main): Use o_file instead of o_default when defining
2394 the .DEFAULT_TARGET special variable.
2395 * read.c (eval): Use define_variable_global() instead of
2396 define_variable() when setting new value for the .DEFAULT_TARGET
2397 special variable. Fixes Savannah bug #12266.
2399 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2401 * imlicit.c (pattern_search): Mark files for which an implicit
2402 rule has been found as targets. Fixes Savannah bug #12202.
2404 2005-03-04 Paul D. Smith <psmith@gnu.org>
2406 * AUTHORS: Update.
2407 * doc/make.texi (Automatic Variables): Document $|.
2409 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2411 * read.c (record_files): Instead of substituting % with
2412 actual stem value in dependency list replace it with $*.
2413 This fixes stem triple expansion bug.
2415 * implicit.c (pattern_search): Copy stem to a separate
2416 buffer and make it a properly terminated string. Assign
2417 this buffer instead of STEM (which is not terminated) to
2418 f->stem. Instead of substituting % with actual stem value
2419 in dependency list replace it with $*. This fixes stem
2420 triple expansion bug.
2422 2005-03-01 Paul D. Smith <psmith@gnu.org>
2424 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2425 on Windows, as it takes a handle not a pid. Just exit.
2426 Fix from patch #3679, provided by Alessandro Vesely.
2428 * configure.in: Update check for sys_siglist[] from autoconf manual.
2429 * signame.c (strsignal): Update to use the new autoconf macro.
2431 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2433 * read.c (record_files): Add a check for the list of prerequisites
2434 of a static pattern rule being empty. Fixes Savannah bug #12180.
2436 2005-02-28 Paul D. Smith <psmith@gnu.org>
2438 * doc/make.texi (Text Functions): Update docs to allow the end
2439 ordinal for $(wordlist ...) to be 0.
2440 * function.c (func_wordlist): Fail if the start ordinal for
2441 $(wordlist ...) is <1. Matches documentation.
2442 Resolves Savannah support request #103195.
2444 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2445 previously we were stopping when !-q, exactly the opposite. This
2446 has been wrong since version 1.34, in 1994!
2447 (update_file): If we got an error don't break out to run more
2448 double-colon rules: just return immediately.
2449 Fixes Savannah bug #7144.
2451 2005-02-27 Paul D. Smith <psmith@gnu.org>
2453 * misc.c (end_of_token): Make argument const.
2454 * make.h: Update prototype.
2456 * function.c (abspath, func_realpath, func_abspath): Use
2457 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2458 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2459 * read.c (record_files): Ditto.
2460 * variable.c (do_variable_definition): Ditto.
2462 * function.c (func_error): Create a new function $(info ...) that
2463 simply prints the message to stdout with no extras.
2464 (function_table_init): Add new function to the table.
2465 * NEWS: Add $(info ...) reference.
2466 * doc/make.texi (Make Control Functions): Document it.
2468 New feature: if the system supports symbolic links, and the user
2469 provides the -L/--check-symlink-time flag, then use the latest
2470 mtime between the symlink(s) and the target file.
2472 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2473 readlink(). If both are available, define MAKE_SYMLINKS.
2474 * main.c: New variable: check_symlink_flag.
2475 (usage): Add a line for -L/--check-symlink-times to the help string.
2476 (switches): Add -L/--check-symlink-times command line argument.
2477 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2478 print a warning and disable it again.
2479 * make.h: Declare check_symlink_flag.
2480 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2481 if the file is a symlink then check each link in the chain and
2482 choose the NEWEST mtime we find as the mtime for the file. The
2483 newest mtime might be the file itself!
2484 * NEWS: Add information about this new feature.
2485 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2487 Avoid core dumps described in Savannah bug # 12124:
2489 * file.c: New variable snapped_deps remember whether we've run
2490 snap_deps().
2491 (snap_deps): Set it.
2492 * filedef.h: Extern it.
2493 * read.c (record_files): Check snapped_deps; if it's set then
2494 we're trying to eval a new target/prerequisite relationship from
2495 within a command script, which we don't support. Fatal.
2497 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2499 Implementation of the .DEFAULT_TARGET special variable.
2501 * read.c (eval): If necessary, update default_target_name when
2502 reading rules.
2503 * read.c (record_files): Update default_target_file if
2504 default_target_name has changed.
2505 * main.c (default_target_name): Define.
2506 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2507 default_target_name is set use default_target_file as a root
2508 target to make.
2509 * filedef.h (default_target_name): Declare.
2510 * dep.h (free_dep_chain):
2511 * misc.c (free_dep_chain): Change to operate on struct nameseq
2512 and change name to free_ns_chain.
2513 * file.c (snap_deps): Update to use free_ns_chain.
2515 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2517 Implementation of the second expansion in explicit rules,
2518 static pattern rules and implicit rules.
2520 * read.c (eval): Refrain from chopping up rule's dependencies.
2521 Store them in a struct dep as a single dependency line. Remove
2522 the code that implements SySV-style automatic variables.
2524 * read.c (record_files): Adjust the code that handles static
2525 pattern rules to expand all percents instead of only the first
2526 one. Reverse the order in which dependencies are stored so that
2527 when the second expansion reverses them again they appear in
2528 the makefile order (with some exceptions, see comments in
2529 the code). Remove the code that implements SySV-style automatic
2530 variables.
2532 * file.c (snap_deps): Implement the second expansion and chopping
2533 of dependency lines for explicit rules.
2535 * implicit.c (struct idep): Define an auxiliary data type to hold
2536 implicit rule's dependencies after stem substitution and
2537 expansion.
2539 * implicit.c (free_idep_chain): Implement.
2541 * implicit.c (get_next_word): Implement helper function for
2542 parsing implicit rule's dependency lines into words taking
2543 into account variable expansion requests. Used in the stem
2544 splitting code.
2546 * implicit.c (pattern_search): Implement the second expansion
2547 for implicit rules. Also fixes bug #12091.
2549 * commands.h (set_file_variables): Declare.
2550 * commands.c (set_file_variables): Remove static specifier.
2552 * dep.h (free_dep_chain): Declare.
2553 * misc.c (free_dep_chain): Implement.
2555 * variable.h (variable_expand_for_file): Declare.
2556 * expand.c (variable_expand_for_file): Remove static specifier.
2558 * make.h (strip_whitespace): Declare.
2559 * function.c (strip_whitespace): Remove static specifier.
2561 2005-02-26 Paul D. Smith <psmith@gnu.org>
2563 * main.c (main): Check for ferror() when reading makefiles from stdin.
2564 Apparently some shells in Windows don't close pipes properly and
2565 require this check.
2567 2005-02-24 Jonathan Grant <jg@jguk.org>
2569 * configure.in: Add MinGW configuration options, and extra w32 code
2570 directory.
2571 * Makefile.am: Add MinGW configuration options, and extra w32 code
2572 directory.
2573 * main.c: Determine correct program string (after last \ without .exe).
2574 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2575 type fix x2
2576 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2577 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2578 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2579 environment support.
2581 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2583 * function.c (func_shell): When initializing error_prefix, check
2584 that reading file name is not null. This fixes long-standing
2585 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2587 2005-02-09 Paul D. Smith <psmith@gnu.org>
2589 * maintMakefile: Update the CVS download URL to simplify them.
2590 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2591 downloading the .texi files from Savannah now.
2593 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2595 * main.c (handle_non_switch_argument): Only add variables to
2596 command_variables if they're not already there: duplicate settings
2597 waste space and can be confusing to read.
2599 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2600 this header is never included by non-WINDOWS32 code, and it
2601 requires <config.h> to define which isn't always included first.
2603 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2604 testing MINGW32 versions.
2606 * main.c (log_working_directory): flush stdout to be sure the WD
2607 change is printed before any stderr messages show up.
2609 2005-02-01 Paul D. Smith <psmith@gnu.org>
2611 * maintMakefile (po_repo): Update the GNU translation site URL.
2613 2004-12-01 Paul D. Smith <psmith@gnu.org>
2615 * main.c (main): Change char* env_shell to struct variable shell_var.
2616 * variable.c (target_environment): Use new shell_var.
2618 2004-11-30 Paul D. Smith <psmith@gnu.org>
2620 * configure.in: The old way we avoided creating build.sh from
2621 build.sh.in before build.sh.in exists doesn't work anymore; we
2622 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2623 the help!). This also keeps automake from complaining.
2624 * Makefile.am (README): Add a dummy target so automake won't
2625 complain that this file doesn't exist when we checkout from CVS.
2626 * maintMakefile (.dep_segment): Rewrite this rule since newer
2627 versions of automake don't provide DEP_FILES.
2629 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2631 Implementation of `realpath' and `abspath' built-in functions.
2633 * configure.in: Check for realpath.
2634 * function.c (abspath): Return an absolute file name that does
2635 not contain any `.' or `..' components, nor repeated `/'.
2636 * function.c (func_abspath): For each name call abspath.
2637 * function.c (func_realpath): For each name call realpath
2638 from libc or delegate to abspath if realpath is not available.
2639 * doc/make.texi (Functions for File Names): Document new functions.
2640 * doc/make.texi (Quick Reference): Ditto.
2642 2004-11-28 Paul D. Smith <psmith@gnu.org>
2644 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2645 arguments. Fixes bug #10252.
2647 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2649 * main.c (main): Set SHELL to v_noexport by default. Remember the
2650 original environment setting of SHELL in the env_shell variable.
2651 * main.h: Export new env_shell variable.
2652 * variable.c (target_environment): If we find a v_noexport
2653 variable for SHELL, add a SHELL variable with the env_shell value.
2654 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2655 * doc/make.texi (Variables/Recursion): Ditto.
2657 2004-11-28 Paul D. Smith <psmith@gnu.org>
2659 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2660 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2661 Patch by Alessandro Vesely.
2663 2004-11-12 Paul D. Smith <psmith@gnu.org>
2665 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2666 the command line if it's inside a string.
2667 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2669 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2671 * function.c (func_lastword): New function: return last word
2672 from the list of words.
2673 * doc/make.texi: Document $(lastword ). Fix broken links in
2674 Quick Reference section.
2676 2004-10-06 Paul D. Smith <psmith@gnu.org>
2678 Apply patch from Alessandro Vesely, provided with bug # 9748.
2679 Fix use of tmpnam() to work with Borland C.
2681 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2682 construction of a temporary filename, and call new function
2683 create_batch_filename().
2684 (create_batch_filename) [WINDOWS32]: New function to create a
2685 temporary filename.
2687 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2689 * read.c (record_target_var): Expand simple pattern-specific
2690 variable.
2691 * variable.c (initialize_file_variables): Do not expand simple
2692 pattern-specific variable.
2694 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2696 * remake.c (update_file_1): When rebuilding makefiles inherit
2697 dontcare flag from a target that triggered update.
2699 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2701 * variable.c (initialize_file_variables): Mark pattern-specific
2702 variable as a per-target and copy export status.
2704 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2706 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2708 * implicit.c (pattern_search): When considering an implicit rule's
2709 prerequisite check that it is actually a target rather then
2710 just an entry in the file hashtable.
2712 2004-09-21 Paul D. Smith <psmith@gnu.org>
2714 * read.c (readstring): Fix some logic errors in backslash handling.
2715 (eval): Remove some unnecessary processing in buffer handling.
2716 (record_target_var): Assert that parse_variable_definition() succeeded.
2717 Reported by: Markus Mauhart <qwe123@chello.at>.
2719 * misc.c: Removed the sindex() function. All instances of this
2720 function were trivially replaceable by the standard strstr()
2721 function, and that function will always have better (or certainly
2722 no worse) performance than the very simple-minded algorithm
2723 sindex() used. This can matter with complex makefiles.
2724 * make.h: Remove the prototype for sindex().
2725 * function.c (subst_expand): Convert sindex() call to strstr().
2726 This means we no longer need to track the TLEN value so remove that.
2727 (func_findstring): Convert sindex() to strstr().
2728 * commands.c (chop_commands): Convert sindex() calls to strstr().
2729 Suggested by: Markus Mauhart <qwe123@chello.at>.
2731 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2732 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2733 If SHELL is set to CMD.EXE then assume it's batch-mode and
2734 non-unixy. I wrote the code differently from the patch, though,
2735 to make it safer. This also resolves bug #9174.
2737 2004-09-20 Paul D. Smith <psmith@gnu.org>
2739 * expand.c (variable_expand_string): Modify to invoke
2740 patsubst_expand() instead of subst_expand(); the latter didn't
2741 handle suffix patterns correctly.
2742 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2743 was used only from variable_expand_string() and is no longer used
2744 there.
2745 (func_subst): Ditto, on call to subst_expand().
2746 (patsubst_expand): Require the percent pointers to point to the
2747 character after the %, not to the % itself.
2748 * read.c (record_files): New call criteria for patsubst_expand().
2749 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2750 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2752 2004-09-19 Paul D. Smith <psmith@gnu.org>
2754 * function.c (subst_expand): Fix a check in by_word: look for a
2755 previous blank if we're beyond the beginning of the string, not
2756 the beginning of the word.
2757 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2759 2004-05-16 Paul D. Smith <psmith@gnu.org>
2761 * remake.c (update_goal_chain): Change the argument specifying
2762 whether we're rebuilding makefiles to be a global variable,
2763 REBUILDING_MAKEFILES.
2764 (complain): Extract the code that complains about no rules to make
2765 a target into a separate function.
2766 (update_file_1): If we tried to rebuild a file during the makefile
2767 rebuild phase and it was dontcare, then no message was printed.
2768 If we then try to build the same file during the normal build,
2769 print a message this time.
2770 (remake_file): Don't complain about un-remake-able files when
2771 we're rebuilding makefiles.
2773 2004-05-11 Paul D. Smith <psmith@gnu.org>
2775 * job.c (construct_command_argv_internal): OS/2 patches from
2776 Andreas Buening <andreas.buening@nexgo.de>.
2778 2004-05-10 Paul D. Smith <psmith@gnu.org>
2780 * remake.c (update_file): Don't walk the double-colon chain unless
2781 this is a double-colon rule. Fix suggested by Boris Kolpackov
2782 <boris@kolpackov.net>.
2784 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2785 * readme.vms: New section describing OpenVMS support and issues.
2786 * default.c (default_variables): Add support for IA64.
2787 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2788 without some privilege aborts make with the error
2789 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2790 pressing Ctrl+Y and the input device is no terminal. The change
2791 catches this error and just continues.
2793 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2795 2004-04-25 Paul D. Smith <psmith@gnu.org>
2797 * commands.c (set_file_variables): Set $< properly in the face of
2798 order-only prerequisites.
2799 Patch from Boris Kolpackov <boris@kolpackov.net>
2801 2004-04-21 Bob Byrnes <byrnes@curl.com>
2803 * main.c (main): Notice failures to remake makefiles.
2805 2004-03-28 Paul D. Smith <psmith@gnu.org>
2807 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2809 * job.c: No default shell for RISC OS.
2810 (load_too_high): Hard-code the return to 1.
2811 (construct_command_argv_internal): No sh_chars or sh_cmds.
2812 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2814 2004-03-20 Paul D. Smith <psmith@gnu.org>
2816 * variable.c (do_variable_definition): Don't append from the
2817 global set if a previous non-appending target-specific variable
2818 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2819 (with fix).
2821 * expand.c (reference_variable): Don't give up on variables with
2822 no value that have the target-specific append flag set: they might
2823 have a value after all. Reported by Oliver Schmidt
2824 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2825 <nikulin@dx1cmd.inp.nsk.su>.
2827 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2828 refer to absolute pathnames in directories that don't exist: some
2829 portion of the makefile could create those directories before we
2830 match the pattern. Fixes bugs #775 and #108.
2832 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2834 * main.c (main): Free makefile_mtimes if we have any.
2835 * README.W32.template: Update documentation for the current status
2836 of the MS-Windows port.
2837 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2838 environment variable is sometimes already defined which causes the
2839 build to fail.
2840 * main.c (debug_signal_handler): Only define this function if
2841 SIGUSR1 is available.
2843 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2845 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2846 * README.OS2.template: Documentation updates.
2847 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2848 link line for safety.
2849 * maintMakefile (build.sh.in): Remove an extraneous ")".
2850 * job.c (child_execute_job): Close saved FDs.
2851 * job.c (exec_command) [OS/2]: exec_command(): If the command
2852 can't be exec'ed and if the shell is not Unix-sh, then try again
2853 with argv = { "cmd", "/c", ... }. Normally, this code is never
2854 reached for the cmd shell unless the command really doesn't exist.
2855 (construct_command_argv_internal) [OS/2]: The code for cmd
2856 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2857 The CMD builtin commands are case insensitive so use strcasecmp().
2859 2004-03-19 Paul D. Smith <psmith@gnu.org>
2861 * read.c (do_define): Re-order line counter increment so the count
2862 is accurate (we were losing one line per define). Reported by
2863 Dave Yost <Dave@Yost.com>.
2865 2004-03-06 Paul D. Smith <psmith@gnu.org>
2867 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2868 compiler.
2869 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2870 * misc.c (message,error,fatal): Ditto.
2871 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2872 * config.h.W32.template: Ditto.
2873 * config.h-vms.template: Ditto.
2874 * config.ami.template: Ditto.
2876 2004-03-04 Paul D. Smith <psmith@gnu.org>
2878 * README.template: Add a note about broken /bin/sh on SunOS
2879 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2881 * misc.c (message, error, fatal): Don't use "..." if we're using
2882 varargs. ansi2knr should handle this but it doesn't work: it
2883 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2884 done. On many systems (SunOS for example) va_dcl is a #define.
2885 So, force the use of the non-"..." version on pre-ANSI compilers.
2887 * maintMakefile (sign-dist): Create some rules to help automate
2888 the new GNU ftp upload method.
2890 2004-02-24 Paul D. Smith <psmith@gnu.org>
2892 * config.h.W32.template: Add HAVE_STDARG_H
2893 * config.h-vms.template: Ditto.
2894 * config.ami.template: Ditto.
2896 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2898 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2899 * build_w32.bat: Remove extra "+".
2901 2004-02-23 Paul D. Smith <psmith@gnu.org>
2903 * make.h: Create an UNUSED macro to mark unused parameters.
2904 * (many): Clean up warnings by applying UNUSED, fixing
2905 signed/unsigned incompatibilities, etc.
2907 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2908 autoconf warnings.
2909 * filedef.h: Name the command_state enumeration.
2910 * file.c (set_command_state): Use the enumeration in the function
2911 argument.
2913 * configure.in: Explicitly set SET_MAKE to empty, to disable
2914 MAKE=make even when no make already exists. Fix bug #3823.
2916 2004-02-22 Paul D. Smith <psmith@gnu.org>
2918 * maintMakefile: Perl script to clean up all non-CVS files. Use
2919 it on all the subdirectories for the cvs-clean target.
2921 * main.c (decode_switches): Require non-empty strings for all our
2922 string command-line options. Fixes Debian bug # 164165.
2924 * configure.in: Check for stdarg.h and varargs.h.
2925 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2926 for printing messages.
2927 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2928 (message): Ditto.
2929 (error): Ditto.
2930 (fatal): Ditto.
2932 A number of patches for OS/2 support from Andreas Buening
2933 <andreas.buening@nexgo.de>:
2935 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2936 disable the SIGCHLD handler.
2937 (reap_children) [OS/2]: Remove special handling of job_rfd.
2938 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2939 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2940 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2941 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2942 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2943 systems.
2945 2004-02-21 Paul D. Smith <psmith@gnu.org>
2947 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2948 <mail@kristov.de> reports that if process_begin() fails we don't
2949 handle the error condition correctly in all cases.
2950 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2951 to have a newline on the message.
2953 * job.c (construct_command_argv_internal): Add "test" to UNIX
2954 sh_cmds[]. Fixes Savannah bug # 7606.
2956 2004-02-04 Paul D. Smith <psmith@gnu.org>
2958 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2959 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2960 Hartmut Becker <Hartmut.Becker@hp.com>.
2962 2004-01-21 Paul D. Smith <psmith@gnu.org>
2964 * job.c (load_too_high): Implement an algorithm to control the
2965 "thundering herd" problem when using -l to control job creation
2966 via the load average. The system only recomputes the load once a
2967 second but we can start many jobs in a second. To solve this we
2968 keep track of the number of jobs started in the last second and
2969 apply a weight to try to guess what a correct load would be.
2970 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2971 Also fixes bug #4693.
2972 (reap_children): Decrease the job count for this second.
2973 (start_job_command): Increase the job count for this second.
2975 * read.c (conditional_line): Expand the text after ifn?def before
2976 checking to see if it's a single word. Fixes bug #7257.
2978 2004-01-09 Paul D. Smith <psmith@gnu.org>
2980 * file.c (print_file): Recurse to print all targets in
2981 double-colon rules. Fixes bug #4518, reported (with patch) by
2982 Andrew Chatham <chatham@google.com>.
2984 2004-01-07 Paul D. Smith <psmith@gnu.org>
2986 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2987 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2988 AC_FUNC_SETVBUF_REVERSED.
2990 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2991 (MAKE Variable): Fix Savannah bug #4898.
2993 * job.c (construct_command_argv_internal): Add "!" to the list of
2994 shell escape chars. POSIX sh allows it to appear before a
2995 command, to negate the exit code. Fixes bug #6404.
2997 * implicit.c (pattern_search): When matching an implicit rule,
2998 remember which dependencies have the ignore_mtime flag set.
2999 Original fix provided in Savannah patch #2349, by Benoit
3000 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3002 2003-11-22 Paul D. Smith <psmith@gnu.org>
3004 * README.W32.template (Outputs): Clarification on -j with
3005 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3006 <jg-make@jguk.org>.
3008 2003-11-02 Paul D. Smith <psmith@gnu.org>
3010 * function.c (func_if): Strip all the trailing whitespace from the
3011 condition, then don't expand it. Fixed bug # 5798.
3013 * expand.c (recursively_expand_for_file): If we're expanding a
3014 variable with no file context, then use the variable's context.
3015 Fixes bug # 6195.
3017 2003-10-21 Paul D. Smith <psmith@gnu.org>
3019 * main.c (log_working_directory): Add newlines to printf()s.
3021 * README.cvs: Add a note to ignore warnings during autoreconf.
3023 * maintMakefile (po_repo): Set a new URL for PO file updates.
3024 (get-config/config.guess get-config/config.sub): Get these files
3025 from the Savannah config project instead of ftp.gnu.org.
3027 2003-10-05 Paul Eggert <eggert@twinsun.com>
3029 * main.c (main): Avoid potential subscript error if environ has
3030 short strings.
3032 2003-08-22 Paul D. Smith <psmith@gnu.org>
3034 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3035 systems which don't yet implement the C89 standard :-/.
3037 2003-07-18 Paul D. Smith <psmith@gnu.org>
3039 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3040 [WINDOWS32]: Initialize hash.
3042 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3044 * dir.c (read_dirstream): Provide a workaround for broken versions of
3045 the MinGW dirent structure.
3047 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3049 * w32/include/dirent.h: Add __MINGW32__ filter.
3051 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3053 * make.h: Add global declaration of *make_host.
3054 * main.c (print_usage): Remove local declaration of *make_host.
3055 (print_version): Display "This program built for ..." after Copyright
3056 notice.
3058 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3060 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3061 execution of "makeinfo --html make.texi".
3063 2003-04-30 Paul D. Smith <psmith@gnu.org>
3065 * build.template: Make some changes to maybe allow this script to
3066 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3068 * README.OS2.template: New file for OS/2 support. Original
3069 contributed by Andreas Buening.
3070 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3071 DOS-style paths.
3073 2003-04-19 Paul D. Smith <psmith@gnu.org>
3075 Fix bug #1405: allow a target to match multiple pattern-specific
3076 variables.
3078 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3079 variable.c, where they've always belonged.
3080 * rule.h: Move the prototypes and struct pattern_var as well.
3081 * variable.c (initialize_file_variables): Invoke
3082 lookup_pattern_var() in a loop, until no more matches are found.
3083 If a match is found, create a new variable set for the target's
3084 pattern variables. Then merge the contents of each matching
3085 pattern variable set into the target's pattern variable set.
3086 (lookup_pattern_var): Change this function to be usable
3087 in a loop. It takes a starting position: if NULL, start at the
3088 beginning; if non-NULL, start with the pattern variable after that
3089 position, and return the next matching pattern.
3090 (create_pattern_var): Create a unique instance of
3091 pattern-specific variables for every definition in the makefile.
3092 Don't combine the same pattern together. This allows us to
3093 process the variable handling properly even when the same pattern
3094 is used multiple times.
3095 (parse_variable_definition): New function: break out the parsing
3096 of a variable definition line from try_variable_definition.
3097 (try_variable_definition): Call parse_variable_definition to
3098 parse.
3099 (print_variable_data_base): Print out pattern-specific variables.
3100 * variable.h (struct variable): Remember when a variable is
3101 conditional. Also remember its flavor.
3102 (struct pattern_var): Instead of keeping a variable set, we just
3103 keep a single variable for each pattern.
3104 * read.c (record_target_var): Each pattern variable contains only a
3105 single variable, not a set, so create it properly.
3106 * doc/make.texi (Pattern-specific): Document the new behavior.
3108 2003-04-17 Paul D. Smith <psmith@gnu.org>
3110 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3111 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3112 file/directory naming rules for VMS so I can't tell whether this
3113 is correct or not.
3115 2003-04-09 Paul D. Smith <psmith@gnu.org>
3117 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3118 DOS-style pathnames: backslash separators and drive specifiers.
3120 2003-03-28 Paul D. Smith <psmith@gnu.org>
3122 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3123 the intermediate flag on all targets. Fixes bug #2515.
3125 2003-03-24 Paul D. Smith <psmith@gnu.org>
3127 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3128 Upgrade to autoconf 2.57 and automake 1.7.3.
3130 * job.c: More OS/2 changes from Andreas Buening.
3132 * file.c (print_file): Fix variable initialization.
3133 Fixes bug #2892.
3135 * remake.c (notice_finished_file):
3137 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3138 some calls (like readdir()) return NULL in valid situations
3139 without resetting errno. Fixes bug #2846.
3141 2003-02-25 Paul D. Smith <psmith@gnu.org>
3143 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3145 * job.c (_is_unixy_shell) [OS/2]: New function.
3146 Set default shell to /bin/sh.
3147 (reap_children): Close the job_rfd pipe here since we don't use a
3148 SIGCHLD handler.
3149 (set_child_handler_action_flags): define this to empty on OS/2.
3150 (start_job_command): Close the jobserver pipe and use
3151 child_execute_job() instead of fork/exec.
3152 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3153 rather than exec'ing, then reconfigure stdin/stdout.
3154 (exec_command): Rewrite to use spawn instead of exec. Return the
3155 PID of the child.
3157 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3158 in DOS. Handle the TEMP environment variable as in DOS. Don't
3159 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3160 use -j in DOS mode. Use child_execute_job() instead of
3161 exec_command().
3163 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3164 spawn() instead.
3166 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3167 prototypes that return values.
3169 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3171 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3172 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3173 for OS/2.
3174 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3175 DOS paths.
3177 2003-02-24 Paul D. Smith <psmith@gnu.org>
3179 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3180 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3181 (child_execute_job) [VMS]: Handle error status properly.
3182 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3184 * function.c (func_shell): Use EINTRLOOP() while reading from the
3185 subshell pipe (Fixes bug #2502).
3186 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3187 jobserver pipe.
3188 * main.c (main): Ditto.
3190 2003-01-30 Paul D. Smith <psmith@gnu.org>
3192 * read.c (eval): eval() was not fully reentrant, because the
3193 collapsed buffer was static. Change it to be an automatic
3194 variable so that eval() can be invoked recursively.
3195 Fixes bug # 2238.
3196 (eval): Apply patch # 1022: fix memory reference error on long
3197 target-specific variable lines.
3198 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3200 * function.c (check_numeric): Combine the is_numeric() function
3201 into this function, since it's only called from one place.
3202 Constify this function. Have it print the incorrect string in the
3203 error message. Fixes bug #2407.
3204 (strip_whitespace): Constify.
3205 (func_if): Constify.
3206 * expand.c (expand_argument): Constify.
3208 2003-01-29 Paul D. Smith <psmith@gnu.org>
3210 Fix bug # 2169, also reported by other people on various systems.
3212 * make.h: Some systems, such as Solaris and PTX, do not fully
3213 implement POSIX-compliant SA_RESTART functionality; important
3214 system calls like stat() and readdir() can still fail with EINTR
3215 even if SA_RESTART has been set on the signal handler. So,
3216 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3217 EINTR for system calls which return -1 or 0 (NULL), respectively,
3218 on error.
3219 Also, remove the old atomic_stat()/atomic_readdir() and
3220 HAVE_BROKEN_RESTART handling.
3222 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3224 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3225 * remake.c (touch_file): Ditto.
3227 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3228 * read.c (construct_include_path): Ditto.
3229 * remake.c (name_mtime): Ditto.
3230 * vpath.c (selective_vpath_search): Ditto.
3231 * dir.c (find_directory): Ditto.
3232 (local_stat): Ditto.
3233 (find_directory): Use ENULLLOOP() to wrap opendir().
3234 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3236 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3237 atomic_readdir() handling.
3239 2003-01-22 Paul D. Smith <psmith@gnu.org>
3241 * function.c (func_call): Fix Bug #1744. If we're inside a
3242 recursive invocation of $(call ...), mask any of the outer
3243 invocation's arguments that aren't used by this one, so that this
3244 invocation doesn't "inherit" them accidentally.
3246 2002-12-05 Paul D. Smith <psmith@gnu.org>
3248 * function.c (subst_expand): Valery Khamenia reported a
3249 pathological performance hit when doing substitutions on very
3250 large values with lots of words: turns out we were invoking
3251 strlen() a ridiculous number of times. Instead of having each
3252 call to sindex() call strlen() again, keep track of how much of
3253 the text we've seen and pass the length to sindex().
3255 2002-11-19 Paul D. Smith <psmith@gnu.org>
3257 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3260 2002-11-16 Paul D. Smith <psmith@gnu.org>
3262 * NMakefile.template (OBJS): Add hash.c object file.
3263 * SMakefile.template (srcs): Ditto.
3264 * Makefile.ami (objs): Ditto.
3265 * build_w32.bat: Ditto.
3267 * Makefile.DOS.template: Remove extra dependencies.
3269 2002-10-25 Paul D. Smith <psmith@gnu.org>
3271 * expand.c (install_variable_buffer): New function. Install a new
3272 variable_buffer context and return the previous one.
3273 (restore_variable_buffer): New function. Free the current
3274 variable_buffer context and put a previously saved one back.
3275 * variable.h: Prototypes for {install,restore}_variable_buffer.
3276 * function.c (func_eval): Push a new variable_buffer context
3277 before we eval, then restore the old one when we're done.
3278 Fixes Bug #1517.
3280 * read.c (install_conditionals): New function. Install a new
3281 conditional context and return the previous one.
3282 (restore_conditionals): New function. Free the current
3283 conditional context and put a previously saved one back.
3284 (eval): Use the {install,restore}_conditionals for "include"
3285 handling.
3286 (eval_buffer): Use {install,restore}_conditionals to preserve the
3287 present conditional state before we evaluate the buffer.
3288 Fixes Bug #1516.
3290 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3291 and $(value ...).
3292 (Recursion): Add a variable index entry for CURDIR.
3294 * README.cvs: Update to appropriate versions.
3295 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3296 don't need to copy loadavg.c: automake is smart enough to create
3297 it for me. Still have a bug in automake related to ansi2knr tho.
3299 2002-10-14 Paul D. Smith <psmith@gnu.org>
3301 * remake.c (notice_finished_file): Only touch targets if they have
3302 at least one command (as per POSIX). Resolve Bug #1418.
3304 * *.c: Convert to using ANSI C-style function definitions.
3305 * Makefile.am: Enable the ansi2knr feature of automake.
3306 * configure.in: ditto.
3308 2002-10-13 Paul D. Smith <psmith@gnu.org>
3310 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3311 for automatic variable values like $^, etc. In the case of very
3312 large lists of prerequisites this causes problems. Instead reuse
3313 a static buffer (resizeable) for each variable.
3315 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3316 target-specific variable definitions. Check for it and set an
3317 "exported" flag.
3318 (record_target_var): Set the export field to v_export if the
3319 "exported" flag is set.
3320 * doc/make.texi (Target-specific): Document the ability to use
3321 "export".
3323 * doc/make.texi: Change the name of the section on automatic
3324 variables from "Automatic" to "Automatic Variables". Added text
3325 clarifying the scope of automatic variables.
3327 2002-10-04 Paul D. Smith <psmith@gnu.org>
3329 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3330 as () braces.
3331 (record_files): Ditto.
3333 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3334 the search for the '=' to only within the enclosing parens.
3336 2002-10-03 Paul D. Smith <psmith@gnu.org>
3338 Version 3.80 released.
3340 * dir.c: Change hash functions to use K&R function definition style.
3341 * function.c: Ditto.
3342 * read.c: Ditto.
3343 * variable.c: Ditto.
3345 Update to automake 1.7.
3347 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3348 (pdf): Remove this target as automake now provides one.
3350 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3352 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3354 * makefile.com: Updates for GNU make 3.80.
3355 * makefile.vms: Ditto.
3357 2002-09-23 Paul D. Smith <psmith@gnu.org>
3359 * read.c (enum make_word_type): Remove w_comment.
3360 (get_next_mword): Don't treat comment characters as special; where
3361 this function is used we will never see a comment (it's stripped
3362 before we get here) and treating comments specially means that
3363 targets like "foo\#bar" aren't handled properly.
3365 2002-09-18 Paul D. Smith <psmith@gnu.org>
3367 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3369 * read.c (eval): Expansion of arguments to export/unexport was
3370 ignoring all arguments after the first one. Change the algorithm
3371 to expand the whole line once, then parse the results.
3373 2002-09-17 Paul D. Smith <psmith@gnu.org>
3375 Fix Bug #940 (plus another bug I found while looking at this):
3377 * read.c (record_target_var): enter_file() will add a new entry if
3378 it's a double-colon target: we don't want to do that in this
3379 situation. Invoke lookup_file() and only enter_file() if it does
3380 not already exist. If the file we get back is a double-colon then
3381 add this variable to the "root" double-colon target.
3383 * variable.c (initialize_file_variables): If this file is a
3384 double-colon target but is not the "root" target, then initialize
3385 the root and make the root's variable list the parent of our
3386 variable list.
3388 2002-09-13 Paul D. Smith <psmith@gnu.org>
3390 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3392 * hash.c (round_up_2): Get rid of a warning.
3394 2002-09-12 Paul D. Smith <psmith@gnu.org>
3396 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3397 so it doesn't complain about getloadavg.c.
3399 * commands.c (set_file_variables): Make sure we always alloca() at
3400 least 1 character for the value of $? (for '\0').
3402 2002-09-11 Paul D. Smith <psmith@gnu.org>
3404 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3405 macro to use RESULT instead of the incorrect _RESULT_.
3407 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3408 and atomic_readdir(). We need to #include dirent.h to get this to
3409 work.
3410 * misc.c (atomic_readdir): Fix typos.
3412 2002-09-10 Paul D. Smith <psmith@gnu.org>
3414 * read.c (eval): Expand variable lists given to export and
3415 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3416 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3418 * doc/make.texi (Variables/Recursion): Document this.
3419 (Conditional Syntax): And here.
3421 2002-09-09 Paul D. Smith <psmith@gnu.org>
3423 * configure.in: Check for memmove().
3425 2002-09-07 Paul D. Smith <psmith@gnu.org>
3427 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3428 Michael Sterrett <msterret@coat.com> reports that while it has
3429 SA_RESTART, it does not work properly.
3431 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3432 that invokes stat() and loops to do it again if it returns EINTR.
3433 (atomic_readdir): Ditto, with readdir().
3435 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3436 and readdir() to atomic_stat() and atomic_readdir().
3438 2002-09-04 Paul D. Smith <psmith@gnu.org>
3440 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3441 reports that GNU make sometimes doesn't recognize that targets can
3442 be made, when directories can be created as prerequisites. He
3443 reports that changing the order of predicates in the DEP->changed
3444 flag test so that lookup_file() is always performed, solves this
3445 problem.
3447 2002-08-08 Paul D. Smith <psmith@gnu.org>
3449 * configure.in: Require a newer version of gettext.
3451 * misc.c (perror_with_name): Translate the format string (for
3452 right-to-left language support).
3453 (pfatal_with_name): Ditto.
3455 * main.c: Create a static array of strings to store the usage
3456 text. This is done to facilitate translations.
3457 (struct command_switch): Remove argdesc and description fields.
3458 (switches): Remove values for obsolete fields.
3459 (print_usage): Print each element of the usage array.
3461 * hash.c: Change function definitions to be K&R style.
3463 2002-08-02 Paul D. Smith <psmith@gnu.org>
3465 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3466 this one because it's too hard to get right. We'll look at it for
3467 a future release.
3468 * main.c (main): Don't create the .TARGETS variable.
3469 * variable.c (handle_special_var): Don't handle .TARGETS.
3471 2002-08-01 Paul D. Smith <psmith@gnu.org>
3473 * main.c (switches): Add a new option, -B (--always-make). If
3474 specified, make will rebuild all targets that it encounters even
3475 if they don't appear to be out of date.
3476 (always_make_flag): New flag.
3477 * make.h: Extern always_make_flag.
3478 * remake.c (update_file_1): Check always_make_flag; if it's set we
3479 will always rebuild any target we can, even if none of its
3480 prerequisites are newer.
3481 * NEWS: Mention it.
3483 * doc/make.texi (Shell Function): Make it clear that make
3484 variables marked as "export" are not passed to instances of the
3485 shell function.
3487 Add new introspection variable .VARIABLES and .TARGETS.
3489 * variable.c (handle_special_var): New function. If the variable
3490 reference passed in is "special" (.VARIABLES or .TARGETS),
3491 calculate the new value if necessary. .VARIABLES is handled here:
3492 walk through the hash of defined variables and construct a value
3493 which is a list of the names. .TARGETS is handled by
3494 build_target_list().
3495 (lookup_variable): Invoke handle_special_var().
3496 * file.c (build_target_list): Walk through the hask of known files
3497 and construct a list of the names of all the ones marked as
3498 targets.
3499 * main.c (main): Initialize them to empty (and as simple variables).
3500 * doc/make.texi (Special Variables): Document them.
3501 * NEWS: Mention them.
3503 * variable.h (struct variable): Add a new flag "exportable" which
3504 is true if the variable name is valid for export.
3505 * variable.c (define_variable_in_set): Set "exportable" when a new
3506 variable is defined.
3507 (target_environment): Use the "exportable" flag instead of
3508 re-checking the name here... an efficiency improvement.
3510 2002-07-31 Paul D. Smith <psmith@gnu.org>
3512 * config.h-vms.template: Updates to build on VMS. Thanks to
3513 Brian_Benning@aksteel.com for helping verify the build.
3514 * makefile.com: Build the new hash.c file.
3515 * hash.h: Use strcpmi(), not stricmp(), in the
3516 HAVE_CASE_INSENSITIVE_FS case.
3518 2002-07-30 Paul D. Smith <psmith@gnu.org>
3520 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3521 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3522 Reported by <Brian_Benning@aksteel.com>.
3524 2002-07-10 Paul D. Smith <psmith@gnu.org>
3526 * variable.c (pop_variable_scope): Remove variable made unused by
3527 new hash infrastructure.
3528 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3529 comparisons as well as name comparisons.
3530 * variable.h: Add a prototype for new hash_init_function_table().
3531 * file.c (lookup_file): Remove variables made unused by new hash
3532 infrastructure.
3533 * dir.c (directory_contents_hash_2): Missing return of hash value.
3534 (dir_contents_file_exists_p): Remove variables made unused by new
3535 hash infrastructure.
3538 Installed Greg McGary's integration of the hash functions from the
3539 GNU id-utils package:
3541 2002-07-10 Greg McGary <greg@mcgary.org>
3543 * scripts/functions/filter-out: Add literals to to the
3544 pattern space in order to add complexity, and trigger
3545 use of an internal hash table. Fix documentation strings.
3546 * scripts/targets/INTERMEDIATE: Reverse order of files
3547 passed to expected `rm' command.
3549 2002-07-10 Greg McGary <greg@mcgary.org>
3551 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

3565 * ar.c (ar_name): Delay call to strlen until needed.
3566 * main.c (initialize_global_hash_tables): New function.
3567 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3568 * misc.c (remove_comments): Pass char constants to find_char_unquote.

3583 (find_directory): Use new hash table package.
3584 (dir_contents_file_exists_p): Likewise.

3604 (lookup_function): Remove `table' argument.
3605 Use new hash table package.
3606 (struct a_word) [chain, length]: New members.
3607 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3608 (struct a_pattern): New struct.
3609 (func_filter_filterout): Pass through patterns noting boundaries
3610 and '%', if present. Note a_word length. Use a hash table if
3611 arglists are large enough to justify cost.
3612 (function_table_init): Renamed from function_table.
3613 (function_table): Declare as `struct hash_table'.
3614 (FUNCTION_TABLE_ENTRIES): New constant.

3622 than a string constant, avoiding zillions of calls to strchr.
3623 Tighten inner search loops to test only for desired delimiters.
3625 * variable.c (variable_hash_1, variable_hash_2,
3626 variable_hash_cmp): New functions.

3641 2002-07-10 Paul D. Smith <psmith@gnu.org>
3643 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3644 prerequisite list. A real SysV make will expand the entire
3645 prerequisites list _twice_: we don't do that as it's a big
3646 backward-compatibility problem. We only replace those specific
3647 variables.
3649 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3650 references left in the list of prerequisites. Check for .POSIX as
3651 we record targets, so we can disable non-POSIX behavior while
3652 reading makefiles as well as running them.
3653 (eval): Check the prerequisite list to see if we have anything
3654 that looks like a SysV prerequisite variable reference.
3656 2002-07-09 Paul D. Smith <psmith@gnu.org>
3658 * doc/make.texi (Prerequisite Types): Add a new section describing
3659 order-only prerequisites.
3661 * read.c (uniquize_deps): If we have the same file as both a
3662 normal and order-only prereq, get rid of the order-only prereq,
3663 since the normal one supersedes it.
3665 2002-07-08 Paul D. Smith <psmith@gnu.org>
3667 * AUTHORS: Added Greg McGary to the AUTHORS file.
3668 * NEWS: Blurbed order-only prerequisites.
3669 * file.c (print_file): Show order-only deps properly when printing
3670 the database.
3672 * maintMakefile: Add "update" targets for wget'ing the latest
3673 versions of various external files. Taken from Makefile.maint in
3674 autoconf, etc.
3676 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3677 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3679 2002-07-07 Paul D. Smith <psmith@gnu.org>
3681 * po/*.po: Remove. We'll use wget to retrieve them at release
3682 time.
3684 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3685 rather than a shell you get an exception. Make sure we look up
3686 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3688 * remake.c (notice_finished_file): Fix handling of -t flag.
3689 Patch provided by Henning Makholm <henning@makholm.net>.
3691 * implicit.c (pattern_search): Some systems apparently run short
3692 of stack space, and using alloca() in this function caused an
3693 overrun. I modified it to use xmalloc() on the two variables
3694 which seemed like they might get large. Fixes Bug #476.
3696 * main.c (print_version): Update copyright notice to conform with
3697 GNU standards.
3698 (print_usage): Update help output.
3700 * function.c (func_eval): Create a new make function, $(eval
3701 ...). Expand the arguments, put them into a buffer, then invoke
3702 eval_buffer() on the resulting string.
3703 (func_quote): Create a new function, $(quote VARNAME). Inserts
3704 the value of the variable VARNAME without expanding it any
3705 further.
3707 * read.c (struct ebuffer): Change the linebuffer structure to an
3708 "eval buffer", which can be either a file or a buffer.
3709 (eval_makefile): Move the code in the old read_makefile() which
3710 located a makefile into here: create a struct ebuffer with that
3711 information. Have it invoke the new function eval() with that
3712 ebuffer.
3713 (eval_buffer): Create a new function that creates a struct ebuffer
3714 that holds a string buffer instead of a file. Have it invoke
3715 eval() with that ebuffer.
3716 (eval): New function that contains the guts of the old
3717 read_makefile() function: this function parses makefiles. Obtains
3718 data to parse from the provided ebuffer. Some modifications to
3719 make the flow of the function cleaner and clearer. Still could
3720 use some work here...
3721 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3722 contents of the define/endef variable from the ebuffer.
3723 (readstring): Read the next line from a string-style ebuffer.
3724 (readline): Read the next line from an ebuffer. If it's a string
3725 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3726 from the file.
3728 * dep.h (eval_buffer): Prototype eval_buffer();
3730 * variable.c (do_variable_definition): Make sure that all
3731 non-target-specific variables are registered in the global set.
3732 If we're invoked from an $(eval ...) we might be inside a $(call
3733 ...) or other function which has pushed a variable scope; we still
3734 want to define our variables from evaluated makefile code in the
3735 global scope.
3737 2002-07-03 Greg McGary <greg@mcgary.org>
3739 * dep.h (struct dep) [ignore_mtime]: New member.
3740 [changed]: convert to a bitfield.
3741 * implicit.c (pattern_search): Zero ignore_mtime.
3742 * main.c (main, handle_non_switch_argument): Likewise.
3743 * rule.c (convert_suffix_rule): Likewise.
3744 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3745 (read_makefile): Parse '|' in prerequisite list.
3746 (uniquize_deps): Consider ignore_mtime when comparing deps.
3747 * remake.c (update_file_1, check_dep): Don't force remake for
3748 dependencies that have d->ignore_mtime.
3749 * commands.c (FILE_LIST_SEPARATOR): New constant.
3750 (set_file_variables): Don't include a
3751 prerequisite in $+, $^ or $? if d->ignore_mtime.
3752 Define $|.
3754 2002-06-18 Paul D. Smith <psmith@gnu.org>
3756 * make.texinfo: Updates for next revision. New date/rev/etc.
3757 Recreate all Info menus. Change license on the manual to the GNU
3758 Free Documentation License. A number of typos.
3759 (Variables Simplify): Don't use "-" before it's defined.
3760 (Automatic Prerequisites): Rewrite the target example to work
3761 properly if the compile fails. Remove incorrect comments about
3762 how "set -e" behaves.
3763 (Text Functions): Move the "word", "wordlist", "words", and
3764 "firstword" functions here, from "File Name Functions".
3765 * make-stds.texi: Update from latest GNU version.
3766 * fdl.texi: (created) Import the latest GNU version.
3768 2002-06-06 Paul D. Smith <psmith@gnu.org>
3770 * variable.c (do_variable_definition): New function: extract the
3771 part of try_variable_definition() that actually sets the value
3772 into a separate function.
3773 (try_variable_definition): Call do_variable_definition() after
3774 parsing the variable definition string.
3775 (define_variable_in_set): Make the name argument const.
3777 * variable.h (enum variable_flavor): Make public.
3778 (do_variable_definition): Create prototype.
3780 * read.c (read_all_makefiles): Create a new built-in variable,
3781 MAKEFILE_LIST.
3782 (read_makefile): Add each makefile read in to this variable value.
3784 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3786 * Makefile.DOS.template: Tweak according to changes in the
3787 distribution. Add back the dependencies of *.o files.
3789 * configh.dos.template: Synchronize with config.h.in.
3791 2002-05-09 Paul D. Smith <psmith@gnu.org>
3793 * file.c (file_timestamp_now): Use K&R function declaration.
3795 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3796 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3797 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3798 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3799 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3800 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3801 nlist.n_name is a pointer rather than an array.
3803 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3804 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3805 * configure.in: Use it instead of the old version.
3807 * main.c (main): Prefer setvbuf() to setlinebuf().
3809 2002-05-08 Paul D. Smith <psmith@gnu.org>
3811 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3812 (loadavg_LDADD): Ditto.
3814 2002-04-29 Paul D. Smith <psmith@gnu.org>
3816 * expand.c (recursively_expand_for_file): Rename
3817 recursively_expand() to recursively_expand_for_file() and provide
3818 an extra argument, struct file. If the argument is provided, set
3819 the variable scope to that of the file before expanding.
3820 * variable.h (recursively_expand): Make this a macro that invokes
3821 recursively_expand_for_file() with a NULL file pointer.
3822 * variable.c (target_environment): Call the renamed function and
3823 provide the current file context.
3824 Fixes Debian bug #144306.
3826 2002-04-28 Paul D. Smith <psmith@gnu.org>
3828 Allow $(call ...) user-defined variables to be self-referencing
3829 without throwing an error. Allows implementation of transitive
3830 closures, among other possibly useful things.
3831 Requested by: Philip Guenther <guenther@sendmail.com>
3833 * variable.h (struct variable): Add a new field: exp_count, and
3834 new macros to hold its size and maximum value.
3835 (warn_undefined): Make this a macro.
3836 * variable.c (define_variable_in_set): Initialize it.
3837 * expand.c (recursively_expand): If we detect recursive expansion
3838 of a variable, check the exp_count field. If it's greater than 0
3839 allow the recursion and decrement the count.
3840 (warn_undefined): Remove this (now a macro in variable.h).
3841 * function.c (func_call): Before we expand the user-defined
3842 function, modify its exp_count field to contain the maximum
3843 number of recursive calls we'll allow. After the call, reset it
3844 to 0.
3846 2002-04-21 Paul D. Smith <psmith@gnu.org>
3848 Modified to use latest autoconf (2.53), automake (1.6.1), and
3849 gettext (0.11.1). We're using gettext's new "external" support,
3850 to avoid including libintl source with GNU make.
3852 * README.cvs: New file. Explain how to build GNU make from CVS.
3854 * configure.in: Modify checking for the system glob library.
3855 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3856 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3857 etc. will manage it correctly). Set an automake conditional
3858 USE_LOCAL_GLOB to decide whether to compile the glob library.
3860 * getloadavg.c (main): Include make.h in the "TEST" program to
3861 avoid warnings.
3863 * Makefile.am: Remove special rules for loadavg. Replace them
3864 with Automake capabilities for building extra programs.
3866 * signame.c: This file does nothing if the system provide
3867 strsignal(). If not, it implements strsignal(). If the system
3868 doesn't define sys_siglist, then we make our own; otherwise we use
3869 the system version.
3870 * signame.h: Removed.
3872 * main.c (main): No need to invoke signame_init(). Update copyright.
3874 * ABOUT-NLS: Removed.
3875 * gettext.c: Removed.
3876 * gettext.h: Get a simplified copy from the gettext package.
3877 * po/*: Created.
3878 * i18n/*.po: Moved to po/.
3879 * i18n/: Removed.
3881 * config/*: Created. Contains package configuration helper files.
3882 * config.guess, config.sub: Moved to config directory.
3884 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3885 Rework to use new-style autoconf features. Use the "external"
3886 mode for gettext. Make the build.sh config file conditional on
3887 whether build.sh.in exists, to avoid autoconf errors.
3888 * acinclude.m4: Removed almost all macros as being obsolete.
3889 Rewrote remaining macros to use AC_DEFINE.
3890 * acconfig.h: Removed.
3892 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3893 conditional to handle customs support. Remove special handling
3894 for i18n features.
3896 2002-04-20 Paul D. Smith <psmith@gnu.org>
3898 * function.c (func_call): Don't mark the argument variables $1,
3899 etc. as recursive. They've already been fully expanded so
3900 there's no need to do it again, and doing so strips escaped $'s.
3901 Reported by Sebastian Glita <glseba@yahoo.com>.
3903 * remake.c (notice_finished_file): Walk through double-colon
3904 entries via the prev field, not the next field!
3905 Reported by Greg McGary <greg@mcgary.org>.
3907 * main.c (main): If the user specifies -q and asks for a specific
3908 target which is a makefile, we got an assert. In that case it
3909 turns out we should continue normally instead.
3911 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3913 * i18n/he.po: Installed a new translation.
3915 2002-01-07 Paul D. Smith <psmith@gnu.org>
3917 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3919 2001-12-04 Paul D. Smith <psmith@gnu.org>
3921 * i18n/ja.po: Installed an updated translation.
3923 2001-09-06 Paul Eggert <eggert@twinsun.com>
3925 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3926 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3928 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3929 are available.
3930 (main): Get rid of any avoidable limit on stack size.
3932 2001-09-04 Paul D. Smith <psmith@gnu.org>
3934 * i18n/da.po: Installed an updated translation.
3936 2001-08-03 Paul D. Smith <psmith@gnu.org>
3938 * i18n/fr.po: Installed an updated translation.
3939 Resolves Debian bug #106720.
3941 2001-06-13 Paul D. Smith <psmith@gnu.org>
3943 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3944 translation.
3946 2001-06-11 Paul D. Smith <psmith@gnu.org>
3948 * i18n/ko.po: Installed a new translation.
3950 2001-05-06 Paul D. Smith <psmith@gnu.org>
3952 Modify the EINTR handling.
3954 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3955 the way in which we manage the file descriptor/signal handler race
3956 trap to be more efficient.
3958 2001-05-06 Paul Eggert <eggert@twinsun.com>
3960 Restart almost all system calls that are interrupted, instead
3961 of worrying about EINTR. The lone exception is the read() for
3962 job tokens.
3964 * configure.in (HAVE_SA_RESTART): New macro.
3965 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3966 * main.c (main): Use SA_RESTART instead of the old,
3967 nonstandard SA_INTERRUPT.
3969 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3970 * main.c (bsd_signal): New function or macro,
3971 if the implementation doesn't supply it.
3972 (The bsd_signal function will be in POSIX 1003.1-200x.)
3973 (HANDLESIG): Remove.
3974 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3976 * make.h (EINTR_SET): Remove.
3977 (SA_RESTART): New macro.
3979 * arscan.c (ar_member_touch): Don't worry about EINTR.
3980 * function.c (func_shell): Likewise.
3981 * job.c (reap_children, free_child, new_job): Likewise.
3982 * main.c (main): Likewise.
3983 * remake.c (touch_file, name_mtime): Likewise.
3985 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3986 if fstat failed with errno!=EINTR, the error was ignored.
3988 * job.c (set_child_handler_action_flags): New function.
3989 (new_job): Use it to temporarily clear the SIGCHLD action flags
3990 while reading the token.
3992 2001-05-02 Paul D. Smith <psmith@gnu.org>
3994 * job.c (start_job_command): Don't add define/endef per-line flags
3995 to the top-level flags setting.
3997 2001-04-03 Paul D. Smith <psmith@gnu.org>
3999 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4000 bit on error, so check for odd return values, not non-0 return
4001 values.
4002 (VMS_get_member_info): Calculate the timezone differences correctly.
4003 Reported by John Fowler <jfowler@nyx.net>.
4006 2001-03-14 Paul D. Smith <psmith@gnu.org>
4008 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4009 value before invoking define_variable().
4010 Reported by John Fowler <jfowler@nyx.net>.
4012 2001-02-07 Paul D. Smith <psmith@gnu.org>
4014 * read.c (record_target_var): If we reset the variable due to a
4015 command-line variable setting overriding it, turn off the "append"
4016 flag.
4018 2001-01-17 Paul D. Smith <psmith@gnu.org>
4020 * variable.c (lookup_variable) [VMS]: When getting values from the
4021 environment, allocate enough space for the _value_ plus escapes,
4022 not enough space for the name plus escapes :-/.
4023 Reported by John Fowler <jfowler@nyx.net>.
4025 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4026 warnings that make generates, so it doesn't look like an error.
4027 Reported by Karl Berry <karl@gnu.org>.
4030 Fix for PR/2020: Rework appended target-specific variables. I'm
4031 fairly confident this algorithm is finally correct.
4033 * expand.c (allocated_variable_append): Rewrite. Instead of
4034 expanding each appended variable then adding all the expanded
4035 strings together, we append all the unexpanded values going up
4036 through the variable set contexts, then expand the final result.
4037 This behaves just like non-target-specific appended variable
4038 values, while the old way didn't in various corner cases.
4039 (variable_append): New function: recursively append the unexpanded
4040 value of a variable, walking from the outermost variable scope to
4041 the innermost.
4042 * variable.c (lookup_variable): Remove the code that looked up the
4043 variable set list if the found variable was "append". We don't
4044 need this anymore.
4045 (lookup_variable_in_set): Make this non-static so we can use it
4046 elsewhere.
4047 (try_variable_definition): Use lookup_variable_in_set() rather
4048 than faking out current_variable_set_list by hand (cleanup).
4049 * variable.h: Add a prototype for the now non-static
4050 lookup_variable_in_set().
4052 2000-11-17 Paul D. Smith <psmith@gnu.org>
4054 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4055 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4056 before throwing a fit.
4058 2000-11-17 Paul D. Smith <psmith@gnu.org>
4060 * read.c (readline): CRLF calculations had a hole, if you hit the
4061 buffer grow scenario just right. Reworked the algorithm to avoid
4062 the need for len or lastlen at all. Problem description with
4063 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4065 2000-10-24 Paul D. Smith <psmith@gnu.org>
4067 * gettext.c (SWAP): Declare this with the prototype, otherwise
4068 some systems don't work (non-32-bit? Reported for Cray T3E).
4069 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4071 2000-10-05 Paul D. Smith <psmith@gnu.org>
4073 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4074 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4076 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4078 2000-09-22 Paul D. Smith <psmith@gnu.org>
4080 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4081 parts of the real gettext.h here, and we expect to really include
4082 the real gettext.h later. If we keep this #define, it's ignored.
4084 2000-09-21 Paul D. Smith <psmith@gnu.org>
4086 * main.c (log_working_directory): Rework the text to use complete
4087 sentences, to make life simpler for the translators.
4089 2000-08-29 Paul D. Smith <psmith@gnu.org>
4091 * file.c (remove_intermediates): Print a debug message before we
4092 remove intermediate files, so the user (if she uses -d) knows
4093 what's going on.
4095 2000-08-21 Paul D. Smith <psmith@gnu.org>
4097 * variable.c (try_variable_definition): Change how we handle
4098 target-specific append variable defns: instead of just setting the
4099 value, expand it as an append _but_ only within the current
4100 target's context. Otherwise we lose all but the last value if the
4101 variable is appended more than once within the current target
4102 context. Fixes PR/1831.
4104 2000-08-16 Paul D. Smith <psmith@gnu.org>
4106 * function.c (func_shell): Nul-terminate the buffer before
4107 printing an exec error message (just in case it's not!).
4108 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4110 2000-07-25 Paul D. Smith <psmith@gnu.org>
4112 * job.c (construct_command_argv_internal): Add "~" to the list of
4113 sh_chars[] which disallow optimizing out the shell call.
4115 2000-07-23 Paul Eggert <eggert@twinsun.com>
4117 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4118 supersedes --disable-nsec-timestamps.
4119 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4120 * README: Remove --disable-nsec-timestamps.
4122 * filedef.h (struct file.low_resolution_time): New member.
4123 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4124 * remake.c (update_file_1):
4125 Avoid spurious rebuilds due to low resolution time stamps,
4126 generalizing the earlier code that applied only to archive members.
4127 (f_mtime): Archive members always have low resolution time stamps.
4129 * configure.in: Remove --disable-nsec-timestamps, as this has
4130 been superseded by .LOW_RESOLUTION_TIME.
4132 2000-07-23 Paul Eggert <eggert@twinsun.com>
4134 * configure.in (enable_nsec_timestamps): Renamed from
4135 make_cv_nsec_timestamps, since enable/disable options
4136 shouldn't be cached.
4138 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4139 and Paul Eggert <eggert@twinsun.com>
4141 * file.c (file_timestamp_now):
4142 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4143 so that clock_gettime is not linked unless needed.
4145 * filedef.h (FILE_TIMESTAMP_HI_RES):
4146 Remove definition; "configure" now does this.
4148 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4149 to before high resolution file timestamp check,
4150 since that check now uses uintmax_t.
4151 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4152 high resolution file timestamps.
4153 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4154 so that we don't link in clock_gettime unnecessarily.
4156 2000-07-17 Paul D. Smith <psmith@gnu.org>
4158 * i18n/ja.po: New version of the translation file.
4160 2000-07-07 Paul D. Smith <psmith@gnu.org>
4162 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4163 the offset calculation.
4164 (name_mtime): Replace EINTR test with EINTR_SET macro.
4166 2000-07-07 Paul Eggert <eggert@twinsun.com>
4168 Fix for PR/1811:
4170 * remake.c (update_file_1):
4171 Avoid spurious rebuilds of archive members due to their
4172 timestamp resolution being only one second.
4173 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4174 the clock's resolution being lower than file timestamps'.
4175 When warning about future timestamps, report only the discrepancy,
4176 not the absolute value of the timestamp and the current time.
4178 * file.c (file_timestamp_now): New arg RESOLUTION.
4179 * filedef.h (file_timestamp_now): Likewise.
4180 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4182 2000-07-05 Paul D. Smith <psmith@gnu.org>
4184 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4185 to listp. Fixes PR/1793.
4187 2000-06-26 Paul Eggert <eggert@twinsun.com>
4189 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4191 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4193 * remake.c (f_mtime): Remove unused var memtime.
4195 2000-06-25 Martin Buchholz <martin@xemacs.org>
4197 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4198 Ran spell-check on make.texinfo.
4200 2000-06-23 Paul D. Smith <psmith@gnu.org>
4202 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4203 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4204 * make.h: Define these macros.
4206 * Version 3.79.1 released.
4208 * configure.in: Add a new option, --disable-nsec-timestamps, to
4209 avoid using sub-second timestamps on systems that support it. It
4210 can lead to problems, e.g. if your makefile relies on "cp -p".
4211 * README.template: Document the issue with "cp -p".
4213 * config.guess, config.sub: Updated.
