527 * variable.h (define_variable_cname): New macro for constant
529 * default.c (set_default_suffixes): Use it.
530 * main.c (main): Ditto.
531 (handle_non_switch_argument): Ditto.
532 (define_makeflags): Ditto.
533 * read.c (read_all_makefiles): Ditto.
534 * variable.c (define_automatic_variables): Ditto.
536 * commands.c (dep_hash_cmp): Avoid casts.
540 2009-10-22 Boris Kolpackov <boris@codesynthesis.com>
542 * read.c (read_all_makefiles): Mark the default makefile dependency
545 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
547 * read.c (do_undefine): Free the expanded variable name.
549 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
550 to normal upgrade logic from dep_hash_cmp to set_file_variables.
552 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
554 * dep.h (uniquize_deps): Remove.
556 * read.c (uniquize_deps): Merge into set_file_variables in
558 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
560 * commands.c (set_file_variables): Avoid modifying the dep
561 chain to achieve uniqueness. Fixes savannah bug 25780.
563 * implicit.c (pattern_search): Instead of re-setting all automatic
564 variables for each rule we try, just update $*.
566 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
568 * variable.h (undefine_variable_in_set): New function declaration.
569 (undefine_variable_global): New macro.
571 * variable.c (undefine_variable_in_set): New function implementation.
573 * read.c (vmodifiers): Add undefine_v modifier.
574 (parse_var_assignment): Parse undefine.
575 (do_undefine): Handle the undefine directive.
576 (eval): Call do_undefine if undefine_v is set.
578 * main.c (.FEATURES): Add a keyword to indicate the new feature.
580 * doc/make.texi (Undefine Directive): Describe the new directive.
582 * NEWS: Add a note about the new directive.
584 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
586 * implicit.c (pattern_search): Initialize file variables only
587 if we need to parse a rule that requires the second expansion.
589 2009-10-03 Paul Smith <psmith@gnu.org>
591 * make.h: Include <alloca.h> even on systems where __GNUC__ is
592 defined. Not sure why it was done the other way.
593 Requested by David Boyce <dsb@boyski.com>.
595 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
597 * dep.h (dep): Add the DONTCARE bitfield.
599 * filedef.h (file):Add the NO_DIAG bitfield.
601 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
602 not struct file (a file can be a dependency of many targets,
603 some don't care, some do).
605 * remake.c (update_goal_chain): Propagate DONTCARE from struct
606 dep to struct file before updating the goal and restore it
608 (update_file): Don't prune the dependency graph if this target
609 has failed but the diagnostics hasn't been issued.
610 (complain): Scan the file's dependency graph to find the file
611 that caused the failure.
612 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
613 whether to print diagnostics.
615 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
617 2009-09-28 Paul Smith <psmith@gnu.org>
619 * doc/make.texi (Pattern Intro): Move the match algorithm
620 discussion into the "Pattern Match" node.
621 (Pattern Match): Expand on the pattern rule matching algorithm.
623 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
625 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
626 much of the command line on a single pass.
628 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
630 * varible.c (create_pattern_var): Insert variables into the
631 PATTERN_VARS list in the shortest patterns first order.
633 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
634 used to sort the rules.
635 (stemlen_compare): Compare two tryrule elements.
636 (pattern_search): Sort the rules so that they are in the shortest
639 * main.c (.FEATURES): Add a keyword to indicate the new behavior.

646 * NEWS: Add a note about the new behavior.
648 2009-09-27 Paul Smith <psmith@gnu.org>
650 * doc/make.texi (Double-Colon): Mention that pattern rules with
651 double-colons have a different meaning. Savannah bug #27497.
653 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
655 * configh.dos.template: Remove unconditional definition of
656 SYS_SIGLIST_DECLARED.
657 Include <sys/version.h> because ports of GCC 4.3.0 and later no
658 longer include it, so macros like __DJGPP_MINOR__ are no longer
659 defined automatically.
661 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
662 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
663 instead of using the hardcoded ones.
664 (SUBDIRS): doc subdir added.
665 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
666 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
667 create html formated docs. texi2html may not be ported to DOS.
668 (make.info, make.dvi, make.ps, make.html): Make targets depend on
670 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
671 -I switch to look in ./ instead of ./doc.
672 (html): Target depend on html-recursive instead of make_1.html.
673 (make_1.html): Removed.
674 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
675 (all-recursive): Allow for more than one subdir in the build
677 (mostlyclean-recursive, clean-recursive, distclean-recursive)
678 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
679 (tags-recursive): Allow for more than one subdir in the build
681 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
682 targets. Enter into doc/ to produce the targets.
683 (all-am): $(INFO_DEPS) replaced by info.
685 2009-09-26 Paul Smith <psmith@gnu.org>
687 * read.c (record_files): Use free_ns() to free struct nameseq.
690 * rule.c (freerule): Use free_dep_chain().
692 * read.c (record_files): Free FILENAMES chain for implicit rules.
693 (eval): Static pattern targets go into the string cache.
695 * function.c (string_glob): Free NAME in the nameseq chain.
697 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
699 * implicit.c (pattern_search): Terminate early if we haven't
700 found any rules to try (performance improvement).
702 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
704 * implicit.c (pattern_search): Merge three parallel arrays,
705 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
706 of struct TRYRULE. In the old version the latter two arrays
707 had insufficient length.
709 2009-09-24 Paul Smith <psmith@gnu.org>
711 * implicit.c (pattern_search): Add back support for order-only
712 prerequisites for secondary expansion implicit rules, that were
713 accidentally dropped. If we find a "|", enable order-only mode
714 and set IGNORE_MTIME on all deps that are seen afterward.
715 (pattern_search): Fix memory leaks: for intermediate files where
716 we've already set the file variable and pattern variable sets, be
717 sure to either save or free them as appropriate.
719 2009-09-23 Paul Smith <psmith@gnu.org>
721 Rework the way secondary expansion is stored, for efficiency.
722 This changes secondary expansion so that ONLY WHEN we know we have
723 a possibility of needing secondary expansion, do we defer the
724 secondary expansion. This means more parsing the deps but we use
725 a lot less memory (due to the strcache). Also, this fixes
728 * read.c (eval): Don't parse the dep string here anymore.
729 (record_files): Take the dep argument as an unparsed string. If
730 secondary expansion is enabled AND the prereq string has a '$' in
731 it, then set NEED_2ND_EXPANSION and keep the entire string.
732 Otherwise, parse the dep string here to construct the dep list
733 with the names in the strcache.
735 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
736 duplicate the name string (others are in the strcache).
738 * implicit.c: Remove struct idep and free_idep_chain(): unused.
739 (struct patdeps): New structure to store prereq information.
740 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
741 which prerequisites need expansion, and expand only those.
743 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
744 and enter_prereqs(). split_prereqs() takes a fully-expanded string
745 and splits it into a DEP list, handling order-only prereqs.
746 (enter_prereqs): This function enters a list of DEPs into the file
747 database. If there's a stem defined, expand any pattern chars.
748 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
749 set. Use the above functions.
750 (snap_deps): Only perform second expansion on prereqs that need it,
751 as defined by the NEED_2ND_EXPANSION flag.
752 (print_prereqs): New function to print the prereqs
753 (print_file): Call print_prereqs() rather than print inline.
755 * hash.h (STRING_COMPARE): Take advantage of strcache() by
757 (STRING_N_COMPARE): Ditto.
758 (ISTRING_COMPARE): Ditto.
760 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
761 (parse_file_seq): Return void*
762 * read.c (parse_file_seq): Return void*.
763 (eval): Invoke macroized version of parse_file_seq()
764 * default.c (set_default_suffixes): Ditto.
765 * file.c (split_prereqs): Ditto.
766 * function.c (string_glob): Ditto.
767 * main.c (main): Ditto.
768 * rule.c (install_pattern_rule): Ditto.
770 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
772 2009-09-16 Paul Smith <psmith@gnu.org>
774 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
776 * dep.h: Create alloc_dep() / free_dep() macros.
778 * implicit.c (pattern_search): Take advantage of the new
779 parse_file_seq() to add the directory prefix to each prereq.
781 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
782 all. Avoid reversing chains. Support adding prefixes.
783 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
784 cached/non-cached results.
785 (eval): Remove multi_glob() & invoke new parse_file_seq().
786 * rule.c (install_pattern_rule): Ditto.
787 * main.c (main): Ditto.
788 * implicit.c (pattern_search): Ditto.
789 * function.c (string_glob): Ditto.
790 * file.c (parse_prereqs): Ditto.
791 * default.c (set_default_suffixes): Ditto.
793 * variable.c (parse_variable_definition): Don't run off the end of
794 the string if it ends in whitespace (found with valgrind).
796 * commands.c (set_file_variables): Keep space for all targets in
797 $? if -B is given (found with valgrind).
799 2009-09-15 Paul Smith <psmith@gnu.org>
801 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
802 (xcalloc): Add new function.
803 * make.h: New declarations.
805 * ar.c (ar_glob_match): New calling method for concat().
806 * main.c (main): Ditto.
807 (decode_env_switches): Ditto.
808 * read.c (eval_makefile): Ditto.
809 (tilde_expand): Ditto.
810 (parse_file_seq): Ditto.
811 * variable.c (target_environment): Ditto.
812 (sync_Path_environment): Ditto.
814 * ar.c (ar_glob_match): Use xcalloc().
815 * dir.c (file_impossible): Ditto.
816 * file.c (enter_file): Ditto.
817 * job.c (new_job): Ditto.
818 * read.c (parse_file_seq): Ditto.
819 * vmsfunctions.c (opendir): Ditto.
821 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
823 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
824 inside the loop that looks up environment for PATH.
826 2009-08-31 Eli Zaretskii <eliz@gnu.org>
828 * function.c (windows32_openpipe): Update envp after calling
829 sync_Path_environment.
831 2009-08-02 Paul Smith <psmith@gnu.org>
833 * remake.c (notice_finished_file): Ensure file->cmds is not null
834 before looping through them. Fixes Savannah bug #21824.
836 * doc/make.texi (Wildcard Examples): Clarify when objects is
837 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
838 (Include): Clarify the behavior of -include.
839 Fixes Savannah bug #18963.
841 2009-08-01 Paul Smith <psmith@gnu.org>
843 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
844 etc. come on the command line. Fixes Savannah bug #27093.
846 * expand.c (expand_argument): If the argument is large enough use
847 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
849 * variable.c (do_variable_definition): Avoid using alloca() to
850 hold values, which can be large. Fixes Savannah bug #23960.
852 * job.c (new_job): Use memmove() instead of strcpy() since both
853 pointers are in the same memory block. Fixes Savannah bug #27148.
854 Patch by Petr Machata.
856 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
858 * job.c (construct_command_argv_internal): Add "ulimit" and
859 "unset" to the sh_cmds for Unixy shells.
861 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
863 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
864 that set make_cv_sys_gnu_glob, so they are also correctly set
865 when the cache has been populated before.
867 2009-07-04 Eli Zaretskii <eliz@gnu.org>
869 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
870 exist, as realpath(3) does where it's supported.
872 2006-07-04 Eli Zaretskii <eliz@gnu.org>
874 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
875 (abspath): Support systems that define HAVE_DOS_PATHS (have
876 drive letters in their file names). Use IS_PATHSEP instead of a
877 literal '/' comparison. Fixes Savannah bug #26886.
879 2009-06-14 Paul Smith <psmith@gnu.org>
881 * remake.c (update_file_1): Remember the original file we marked
882 as updating, so we can clear that flag again. If we find a target
883 via vpath, FILE might change.
884 (check_dep): Ditto. Fixes Savannah bug #13529.
885 Patch by Reid Madsen <reid.madsen@tek.com>.
887 2009-06-13 Paul Smith <psmith@gnu.org>
889 * doc/make.texi (MAKEFILES Variable): Be explicit that files
890 included by MAKEFILES cannot give default goals.
891 * read.c (eval): If set_default is not set, pass the no-default-goal
892 value when we read included makefiles. Fixes Savannah bug #13401.
894 * ar.c (ar_name): Ensure that targets with empty parens aren't
895 considered archive member references: archive members must have a
896 non-empty "member" string. Fixes Savannah bug #18435.
898 * function.c (string_glob): Rely on multi_glob() to determine
899 whether files exist or not. Remove call to file_exists_p() which
900 is not always correct. Fixes Savannah bug #21231.
901 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
902 then only files that really exist will be returned.
903 * dep.h: Add new argument to multi_glob().
904 * rule.c (install_pattern_rule): Ditto.
905 * read.c (eval): Ditto.
906 * main.c (main): Ditto.
907 * implicit.c (pattern_search): Ditto.
908 * file.c (parse_prereqs): Ditto.
909 * default.c (set_default_suffixes): Ditto.
911 2009-06-09 Paul Smith <psmith@gnu.org>
913 * commands.c (set_file_variables): If always_make_flag is set,
914 always add the prereq to $?. Fixes Savannah bug #17825.
916 * remake.c (update_file_1): When rebuilding deps of FILE, also try
917 to rebuild the deps of all the also_make targets for that file.
918 Fixes Savannah bug #19108.
920 * implicit.c (pattern_search): Undo test for is_target, added by
921 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
922 Rule Search Algorithm". Fixes Savannah bug #17752.
924 * main.c (clean_jobserver): Clear the jobserver_fds options and
925 set job_slots to the default when we clean up.
926 (define_makeflags): Return the new MAKEFLAGS value.
927 (main): Reset MAKEFLAGS in the environment when we re-exec.
928 Fixes Savannah bug #18124.
930 2009-06-08 Paul Smith <psmith@gnu.org>
932 * read.c (eval): Collapse continuations post-semicolon on target-
933 specific variables. Fixes Savannah bug #17521.
935 2009-06-07 Paul Smith <psmith@gnu.org>
937 * job.c (reap_children): For older systems without waitpid() (are
938 there any of these left?) run wait(2) inside EINTRLOOP to handle
939 EINTR errors. Fixes Savannah bug #16401.
941 * (various): Debug message cleanup. Fixes Savannah bug #16469.
943 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
945 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
946 not the end, to catch second expansion $(eval ...) defining new
947 target/prereq relationships during snap_deps.
948 Fixes Savannah bug #24622.
950 * read.c (record_files): The second-expansion "f->updating" hack
951 was not completely correct: if assumed that the target with
952 commands always had prerequisites; if one didn't then the ordering
953 was messed up. Fixed for now to use f->updating to decide whether
954 to preserve the last element in the deps list... but this whole
955 area of constructing and reversing the deps list is too confusing
956 and needs to be reworked. Fixes Savannah bug #21198.
958 2009-06-06 Paul Smith <psmith@gnu.org>
960 * hash.c (hash_insert): Remove useless test for NULL.
961 Fixes Savannah bug #21823.
963 * make.h: Move SET_STACK_SIZE determination to make.h.
964 * main.c (main): New global variable, STACK_LIMIT, holds the
965 original stack limit when make was started.
966 * job.c (start_job_command): Reset the stack limit, if we changed it.
967 Fixes Savannah bug #22010.
969 * remake.c (check_dep): Only set the target's state to not-started
970 if it's not already running. Found this while testing -j10 builds
971 of glibc: various targets were being rebuilt multiple times.
972 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
975 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
976 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
979 2009-06-04 Paul Smith <psmith@gnu.org>
981 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
983 * maintMakefile: Modify access of config and gnulib Savannah
984 modules to use GIT instead of CVS.
986 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
987 Fixes Savannah bug #24655.
989 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
990 this can happen during some invocations of $(eval ...) for example.
991 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
993 2009-06-02 Paul Smith <psmith@gnu.org>
995 * configure.in: Check for fileno()
996 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
997 for the makefile file so invocations of $(shell ...) don't inherit it.
998 Fixes Savannah bug #24277.
1000 2009-06-01 Paul Smith <psmith@gnu.org>
1002 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1003 expansion was handled incorrectly. Rework the default goal
1004 handling to save the variable only. Remove default_goal_file and
1006 * read.c (eval): Check default_goal_var, not default_goal_name.
1007 * read.c (record_target_var): Don't check default_goal_file here.
1009 2009-05-31 Paul Smith <psmith@gnu.org>
1011 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1012 it, and if the multi_glob() returns nothing (say it expanded to
1013 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1015 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1016 $(and ..) to the reference. Fixes Savannah bug #25694.
1018 * make.1: Be clear that some recipes will be executed even with -n.
1019 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1021 * doc/make.texi (Override Directive): Make more clear how
1022 overrides and appends interact.
1023 Elucidates part of Savannah bug #26207.
1025 * read.c (record_target_var): Don't reset the origin on
1026 target-specific variables; try_variable_definition() will handle
1027 this correctly. Fixes Savannah bug #26207.
1029 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1030 Fixes Savannah bug #25712.
1032 * implicit.c (pattern_search): Keep a pointer to the beginning of
1033 the filename and save that instead of the constructed pointer.
1034 Fixes Savannah bug #26593.
1035 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1037 2009-05-30 Paul Smith <psmith@gnu.org>
1039 * doc/make.texi (Multi-Line): Add a description of the new abilities
1040 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1041 "command sequence" vs. "recipe" syntax.
1042 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1043 after a define, to create variables with those flavors.
1045 2009-05-25 Paul Smith <psmith@gnu.org>
1047 Reworked the parser for variable assignments to allow multiple
1048 modifiers, and in any order. Also allows variable and
1049 prerequisites to be modifier names ('export', 'private', etc.)
1051 * NEWS: Add notes about user-visible changes.
1053 * read.c (struct vmodifiers): Remember what modifiers were seen.
1054 (parse_var_assignment): New function to parse variable assignments.
1055 (eval): Call the new function. Handle variable assignments earlier.
1057 * variable.c (parse_variable_definition): Only parse; don't create var.
1058 (assign_variable_definition): Call parse, then create the var.
1060 2009-05-24 Paul Smith <psmith@gnu.org>

1088 -t with phony targets.
1090 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>

1176 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1178 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1179 HAVE_DECL_SYS_SIGLIST.
1181 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1182 build does not use child_execute_job.
1184 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1185 export the SHELL environment variable to the child.
1187 2007-12-22 Eli Zaretskii <eliz@gnu.org>

1209 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1211 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1212 a more complex value than a simple shell: if it's not a default
1213 shell now then expand it and see if is a default shell then.
1215 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1217 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1218 pathnames, with const strings.
1219 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1241 * doc/make.texi (Special Variables): Moved this into the "How to
1242 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1247 (Rule Syntax): Ditto.
1248 (Command Syntax): Ditto.
1249 (Error Messages): Ditto.
1251 2007-09-10 Paul Smith <psmith@gnu.org>
1253 * commands.c (print_commands): Don't print an extra line in the
1254 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1256 * read.c (construct_include_path): Add the full string to the cache; we
1257 were chopping the last char.
1259 * NEWS: Announce the .RECIPEPREFIX special variable.
1260 * variable.c (lookup_special_var): Rename from handle_special_var().
1261 (lookup_variable): Call the new name.

1266 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1267 * main.c (main): Create the .RECIPEPREFIX special variable.
1268 * read.c (eval): Remove the cmd_prefix characters from the command
1269 scripts here, so they're not stored in the commands array at all,
1270 rather than waiting and stripping them out during command construction.
1271 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1273 2007-08-15 Paul Smith <psmith@gnu.org>
1275 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1276 file has had the section info removed, so add some to make.texi
1277 before we include it.
1279 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1281 * remake.c (check_dep): Reset the target state for intermediate

1297 2007-07-13 Paul Smith <psmith@gnu.org>
1299 * file.c (expand_deps): Use variable_buffer as the start of the
1300 buffer, not the original pointer (in case it was reallocated).
1301 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1302 Fixes Savannah bug #20452.
1304 2007-07-04 Paul Smith <psmith@gnu.org>

1327 * job.c (new_job): Add debug info to specify where make found the
1328 command script it is running to build a target.
1329 Fixes Savannah bug #18617.

1339 Dave Korn <dave.korn@artimi.com>
1341 2007-05-08 Paul Smith <psmith@gnu.org>
1343 Fix Savannah bug #19656:
1345 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1347 * make.h: Change all case-insensitive string compares to use
1348 strcasecmp() (from POSIX). If we don't have that but do have one
1349 of the others, define strcasecmp to be one of those instead. If
1350 we don't have any, declare a prototype for our own version.
1352 * misc.c (strcasecmp): Use this if we can't find any native
1353 case-insensitive string comparison function.
1354 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1355 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1357 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1358 strcasecmp() instead of stricmp().
1359 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1360 instead of strcmpi().
1361 * acinclude.m4: Remove the strcasecmp() check from here.
1363 2007-03-21 Paul Smith <psmith@gnu.org>
1365 * configure.in: Don't turn on case-insensitive file system support
1366 if --disable-... is given. Fixes Savannah bug #19348.
1368 2007-03-19 Paul Smith <psmith@gnu.org>
1370 * ALL: Use the strcache for all file name strings, or other
1371 strings which we will never free. The goal is to save memory by
1372 avoiding duplicate copies of strings. However, at the moment this
1373 doesn't save much memory in most situations: due to secondary
1374 expansion we actually save prerequisite lists twice (once before
1375 the secondary expansion, and then again after it's been parsed
1376 into individual file names in the dep list). We will resolve this
1377 in a future change, by doing the parsing up-front for targets
1378 where secondary expansion is not set.
1380 Moving things into the strcache also allows us to use const
1381 pointers in many more places.
1383 2007-01-03 Paul Smith <psmith@gnu.org>
1385 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1386 the function, not just the first. Fixes Savannah bug #18680.
1388 2006-11-18 Paul Smith <psmith@gnu.org>
1390 * strcache.c (strcache_add_len): Don't allocate a new buffer
1391 unless the string is not already nil-terminated. Technically this
1392 is a violation of the standard, since we may be passed an array
1393 that is not long enough to test one past. However, in make this
1394 is never true since we only use nil-terminated strings or
1395 sub-strings thereof.
1397 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1399 * main.c: New global cmd_prefix, defaults to '\t'.
1400 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1403 * dir.c: Constified.
1404 (dir_contents_file_exists_p): Check for an error return from
1405 readdir(), just in case.
1407 * commands.c: Constified.
1408 * default.c: Constified.
1409 * expand.c: Constified.
1410 * function.c: Partial constification.
1411 * variable.c: Partial constification.
1412 * vmsify.c: Constification. Hard to test this but I hope I didn't
1414 * vpath.c: Partial constification.
1415 * w32/pathstuff.c: Partial constification.
1417 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1419 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1420 backslashes and drive letters as absolute.
1422 2006-10-22 Paul Smith <psmith@gnu.org>
1424 * main.c (struct command_switch): Use const and void*.
1426 2006-10-21 Paul Smith <psmith@gnu.org>
1429 * arscan.c: Constified.
1431 2006-09-30 Paul Smith <psmith@gnu.org>
1433 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1434 point to lastword since the example was updated.
1435 Fixes Savannah bug #16304.
1436 (Secondary Expansion): Correct example description.
1437 Fixes Savannah bug #16468.
1438 (Makefile Contents): Clarify that comments cannot appear within
1439 variable references or function calls.
1440 Fixes Savannah bug #16577.
1441 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1442 Fixes Savannah bug #17701.
1443 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1445 prerequisites. Fixes Savannah bug #17880.
1446 (Rule Syntax): "lise" -> "list"
1447 (Multiple Rules): ... -> @dots{}
1448 (Splitting Lines): ditto.

1451 considered changed, for the purposes of $?.
1452 Fixes Savannah bug #16051.
1454 * make.1: Remove extraneous "+".
1455 Fixes Savannah bug #16652.
1457 2006-09-06 Paul D. Smith <psmith@gnu.org>

1472 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1473 sh_chars_sh for Windows platforms that emulate Unix.
1475 2006-05-07 Paul D. Smith <psmith@gnu.org>
1477 * README.OS2.template: Updates provided by Andreas Buening
1478 <andreas.buening@nexgo.de>.

1507 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1508 values from memory allocation functions: they return void* and so
1509 don't need to be cast. Also remove (char *) casts of arguments to
1512 * configure.in: Remove checks for memcpy/memmove/strchr.
1514 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

1524 2006-04-06 Paul D. Smith <psmith@gnu.org>
1526 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1527 require an ISO C 1989 standard compiler and runtime library.

1559 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1560 with lastslash, since the latter points to filename, not to
1562 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1563 Declare and define sh_chars_sh[].
1565 2006-03-23 Paul D. Smith <psmith@gnu.org>
1567 * configure.in: Look for build.sh.in in $srcdir so it will be
1568 built for remote configurations as well.
1570 * Makefile.am: Make sure to clean up build.sh during distclean.
1571 Fixes Savannah bug #16166.
1573 * misc.c (log_access): Takes a const char *.

1586 memory on hosts that don't support it directly.
1588 * README.cvs: Add information on steps for making a release (to
1589 make sure I don't forget any).
1591 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1593 (die): Cleanup code was removed from here; call the new function.
1594 (main): If we are re-execing, clean up the jobserver first so we
1595 don't leak file descriptors.
1596 Reported by Craig Fithian <craig.fithian@citigroup.com>
1598 2006-03-17 Paul D. Smith <psmith@gnu.org>
1600 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1601 allow multiple concurrent runs.
1602 Patch from Joseph Myers <joseph@codesourcery.com>
1604 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1606 * dep.h (struct dep): Add the stem field.
1607 * misc.c (alloc_dep, free_dep): New functions.
1608 (copy_dep_chain): Copy stem.
1609 (free_dep_chain): Use free_dep.
1610 * read.c (record_files): Store stem in the dependency line.
1611 * file.c (expand_deps): Use stem stored in the dependency line. Use
1612 free_dep_chain instead of free_ns_chain.
1613 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1614 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1615 * main.c (main, handle_non_switch_argument): Ditto.
1616 * remake.c (check_dep): Ditto.
1617 * rule.c (convert_suffix_rule, freerule): Ditto.
1619 2006-03-14 Paul D. Smith <psmith@gnu.org>
1621 * expand.c (variable_append): Instead of appending everything then
1622 expanding the result, we expand (or not, if it's simple) each part
1624 (allocated_variable_append): Don't expand the final result.
1625 Fixes Savannah bug #15913.
1627 2006-03-09 Paul Smith <psmith@gnu.org>
1629 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1630 listed non-existent files as changed. Turns out there's a bug in
1631 the Linux kernel builds which means that this change causes
1632 everything to rebuild every time. We will re-introduce this fix
1633 in the next release, to give them time to fix their build system.
1634 Fixes Savannah bug #16002.
1635 Introduces Savannah bug #16051.
1637 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1638 we *don't* find UNIX "/".

1644 locator function find_and_set_default_shell if SHELL came from the
1647 2006-02-20 Paul D. Smith <psmith@gnu.org>
1649 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1650 to be null; don't core in that case.
1652 2006-02-19 Paul D. Smith <psmith@gnu.org>
1654 * commands.c (set_file_variables): Realloc, not malloc, the static
1655 string values to avoid memory leaks.
1657 * expand.c (recursively_expand_for_file): Only set reading_file to
1658 an initialized value.
1660 * implicit.c (pattern_search): We need to make a copy of the stem
1661 if we get it from an intermediate dep, since those get freed.
1663 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1665 (enter_file) [VMS]: Ditto.
1666 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1668 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1670 * job.c (construct_command_argv_internal): Fix last change.
1672 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1673 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1674 the calls to _beginthreadex.
1676 * expand.c (recursively_expand_for_file): Initialize `save' to
1677 prevent compiler warnings.
1679 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1681 * job.c (construct_command_argv_internal): Don't create a temporary
1682 script/batch file if we are under -n. Call _setmode to switch the
1683 script file stream to text mode.
1685 2006-02-17 Paul D. Smith <psmith@gnu.org>
1687 * variable.c (merge_variable_set_lists): Don't try to merge the
1688 global_setlist. Not only is this useless, but it can lead to
1689 circularities in the linked list, if global_setlist->next in one
1690 list gets set to point to another list which also ends in
1692 Fixes Savannah bug #15757.
1694 2006-02-15 Paul D. Smith <psmith@gnu.org>
1696 Fix for Savannah bug #106.
1698 * expand.c (expanding_var): Keep track of which variable we're
1699 expanding. If no variable is being expanded, it's the same as
1701 * make.h (expanding_var): Declare it.
1702 * expand.c (recursively_expand_for_file): Set expanding_var to the
1703 current variable we're expanding, unless there's no file info in
1704 it (could happen if it comes from the command line or a default
1705 variable). Restore it before we exit.
1706 * expand.c (variable_expand_string): Use the expanding_var file
1707 info instead of the reading_file info.
1708 * function.c (check_numeric): Ditto.
1710 (func_wordlist): Ditto.
1711 (func_error): Ditto.
1712 (expand_builtin_function): Ditto.
1713 (handle_function): Ditto.
1715 2006-02-14 Paul D. Smith <psmith@gnu.org>
1717 * read.c (eval): Even if the included filenames expands to the
1718 empty string we still need to free the allocated buffer.
1720 * implicit.c (pattern_search): If we allocated a variable set for
1721 an impossible file, free it.
1722 * variable.c (free_variable_set): New function.
1723 * variable.h: Declare it.
1725 * read.c (read_all_makefiles): Makefile names are kept in the
1726 strcache, so there's never any need to alloc/free them.
1729 * main.c (main): Add "archives" to the .FEATURES variable if
1730 archive support is enabled.
1731 * doc/make.texi (Special Variables): Document it.
1733 2006-02-13 Paul D. Smith <psmith@gnu.org>
1735 * implicit.c (pattern_search): Add checking for DOS pathnames to
1736 the pattern rule target LASTSLASH manipulation.

1741 * (ALL FILES): Updated copyright and license notices.
1743 2006-02-10 Paul D. Smith <psmith@gnu.org>
1745 A new internal capability: the string cache is a read-only cache
1746 of strings, with a hash table interface for fast lookup. Nothing
1747 in the cache will ever be freed, so there's no need for reference
1748 counting, etc. This is the beginning of a full solution for
1749 Savannah bug #15182, but for now we only store makefile names here.
1751 * strcache.c: New file. Implement a read-only string cache.
1752 * make.h: Add prototypes for new functions.
1753 * main.c (initialize_global_hash_tables): Initialize the string cache.
1754 (print_data_base): Print string cache stats.
1755 * read.c (eval_makefile): Use the string cache to store makefile
1756 names. Rewrite the string allocation to be sure we free everything.
1758 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1760 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1761 directory time stamp didn't change, except on FAT filesystems.
1762 Suggested by J. David Bryan <jdbryan@acm.org>.
1764 2006-02-09 Paul D. Smith <psmith@gnu.org>
1766 * function.c (func_or): Implement a short-circuiting OR function.
1767 (func_and): Implement a short-circuiting AND function.
1768 (function_table_init): Update the table with the new functions.
1769 * doc/make.texi (Conditional Functions): Changed the "if" section
1770 to one on general conditional functions. Added documentation for
1771 $(and ...) and $(or ...) functions.
1772 * NEWS: Note new $(and ...) and $(or ...) functions.

1777 * job.c (new_job): Cache dontcare flag.
1778 * job.c (reap_children): Use cached dontcare flag instead of the
1779 one in struct file. Fixes Savannah bug #15641.
1781 2006-02-06 Paul D. Smith <psmith@gnu.org>
1783 * vpath.c (selective_vpath_search): If the file we find has a
1784 timestamp from -o or -W, use that instead of the real time.
1785 * remake.c (f_mtime): If the mtime is a special token from -o or
1786 -W, don't overwrite it with the real mtime.
1787 Fixes Savannah bug #15341.
1789 Updates from Markus Mauhart <qwe123@chello.at>:
1791 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1792 (process_signal, process_last_err, process_exit_code): Manage
1793 invalid handle values.
1794 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1795 manage invalid handles; remove them.

1804 Fixes Savannah bug #15533.
1805 * filedef.h (struct file): Add a new LAST pointer.
1807 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1808 the comparison. For 64-bits systems the result of the subtraction
1809 might not fit into an int. Use comparison instead.
1810 Fixes Savannah bug #15534.
1812 * doc/make.texi: Update the chapter on writing commands to reflect
1813 the changes made in 3.81 for backslash/newline and SHELL handling.
1815 2006-02-01 Paul D. Smith <psmith@gnu.org>
1817 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1833 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1835 * remake.c (update_goal_chain): Set g->changed instead of
1836 incrementing it, as it is only 8-bit wide, and could overflow if
1837 many commands got started in update_file.
1839 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1841 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1842 MAXIMUM_WAIT_OBJECTS.

1850 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1851 are already more children than sub_proc.c can handle, behave as if
1852 the load were too high.
1853 (start_job_command): Fix a typo in error message when process_easy
1856 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1858 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1859 the shell is not sh.exe.
1861 * job.c (create_batch_file): Renamed from create_batch_filename;
1862 all callers changed. Don't close the temporary file; return its
1863 file descriptor instead. New arg FD allows to return the file
1865 (construct_command_argv_internal): Use _fdopen instead of fopen to
1866 open the batch file.
1868 2006-01-04 Paul D. Smith <psmith@gnu.org>
1870 * readme.vms: Updates for case-insensitive VMS file systems from

1898 handling of backslash-newline sequences. Mention the differences
1899 on MS-DOS and MS-Windows.
1901 * NEWS: More details about building the MinGW port and a pointer
1902 to README.W32. Fix the section name that describes the new
1903 backward-incompatible processing of backslash-newline sequences.
1904 The special processing of SHELL set to "cmd" is only relevant to
1905 MS-Windows, not MS-DOS.
1907 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1909 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1910 to DWORD, to avoid compiler warnings.
1911 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1912 use %ld in format, to avoid compiler warnings.

1932 * make.1: Fix some display errors and document all existing options.
1933 Patch by Mike Frysinger <vapier@gentoo.org>.
1935 2005-12-11 Paul D. Smith <psmith@gnu.org>
1937 * implicit.c (pattern_search): If 2nd expansion is not set for
1938 this implicit rule, replace the pattern with the stem directly,
1939 and don't re-expand the variable list. Along with the other
1940 .SECONDEXPANSION changes below, fixes bug #13781.
1942 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1944 * implicit.c (pattern_search): Mark other files that this rule
1945 builds as targets so that they are not treated as intermediates
1946 by the pattern rule search algorithm. Fixes bug #13022.
1948 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1950 * remake.c (notice_finished_file): Propagate the change of

1971 * maintMakefile: We only need to build the templates when we are
1972 creating a distribution, so don't do it for "all".
1974 2005-10-24 Paul D. Smith <psmith@gnu.org>
1976 Make secondary expansion optional: its enabled by declaring the
1977 special target .SECONDEXPANSION.
1979 * NEWS: Update information on second expansion capabilities.
1980 * doc/make.texi (Secondary Expansion): Document the
1981 .SECONDEXPANSION special target and its behavior.

1990 * implicit.c (pattern_search): Initialize the new staticpattern
1992 * main.c (second_expansion): Declare a global variable to remember
1993 if the special target has been seen. Initialize the new
1994 staticpattern field for prerequisites.
1995 * make.h: Extern for second_expansion.
1996 * misc.c (free_dep_chain): New function: frees a struct dep list.
1997 * read.c (read_all_makefiles): Initialize the staticpattern field.

2002 Set the staticpattern field for prereqs of static pattern targets.
2004 2005-10-16 Paul D. Smith <psmith@gnu.org>
2006 * main.c (main): Set CURDIR to be a file variable instead of a
2007 default, so that values of CURDIR inherited from the environment
2008 won't override the make value.
2010 2005-09-26 Paul D. Smith <psmith@gnu.org>
2012 * job.c (construct_command_argv_internal): If the line is empty
2013 remember to free the temporary argv strings.
2016 2005-09-16 Paul D. Smith <psmith@gnu.org>
2018 * job.c (start_job_command): The noerror flag is a boolean (single
2019 bit); set it appropriately.
2020 Reported by Mark Eichin <eichin@metacarta.com>
2022 2005-08-29 Paul D. Smith <psmith@gnu.org>
2024 * function.c (func_error): On Windows, output from $(info ...)
2025 seems to come in the wrong order. Try to force it with fflush().
2027 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2029 * read.c (record_files): Move code that sets stem for static
2030 pattern rules out of the if (!two_colon) condition so it is
2031 also executed for two-colon rules. Fixes Savannah bug #13881.
2033 2005-08-08 Paul D. Smith <psmith@gnu.org>
2035 * make.h: Don't test that __STDC__ is non-0. Some compilers
2036 (Windows for example) set it to 0 to denote "ISO C + extensions".
2039 2005-08-07 Paul D. Smith <psmith@gnu.org>
2041 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2042 conditional (slightly different version of a fix from Eli).
2044 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2045 If make is running in parallel without -k and two jobs die in a
2046 row, but not too close to each other, then make will quit without
2047 waiting for the rest of the jobs to die.
2049 * main.c (die): Don't reset err before calling reap_children() the
2050 second time: we still want it to be in the error condition.

2052 to control whether or not the error message should be printed.
2054 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2056 * w32/subproc/sub_proc.c: Include signal.h.
2057 (process_pipe_io, process_file_io): Pass a pointer to a local
2058 DWORD variable to GetExitCodeProcess. If the exit code is
2059 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2061 * job.c [WINDOWS32]: Include windows.h.
2062 (main_thread) [WINDOWS32]: New global variable.
2063 (reap_children) [WINDOWS32]: Get the handle for the main thread
2064 and store it in main_thread.
2066 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2067 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2068 doing anything else. When we are done, close the main thread
2069 handle and exit with status 130.
2071 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2073 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2076 * main.c (find_and_set_default_shell): If found a DOSish shell,
2077 set sh_found and the value of default_shell, and report the
2078 findings in debug mode.
2080 * job.c (construct_command_argv_internal): Check unixy_shell, not
2081 no_default_sh_exe, to decide whether to use Unixy or DOSish
2084 * README.W32: Update with info about the MinGW build.
2086 * build_w32.bat: Support MinGW.
2088 * w32/subproc/build.bat: Likewise.
2090 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2091 printing DWORD args.
2093 * function.c (windows32_openpipe): Fix format strings for printing
2096 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2098 (start_job_command): Fix format string for printing the result of
2100 (start_job_command) [WINDOWS32]: Do not define.
2101 (exec_command): Fix format string for printing HANDLE args.
2103 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2104 to avoid compiler warnings.
2105 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2106 (Note: some of these fixes were submitted independently by J. Grant)
2108 2005-07-30 J. Grant <jg@jguk.org>
2110 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2111 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2112 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2114 2005-07-15 Paul Smith <psmith@gnu.org>
2116 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2117 we don't have a POSIX shell, then revert to the old
2118 backslash-newline behavior (where they are stripped).
2121 2005-07-08 Paul D. Smith <psmith@gnu.org>
2123 * config.h.W32.template: Reorder to match the standard config.h,
2124 for easier comparisons.
2125 From J. Grant <jg@jguk.org>
2127 * maintMakefile: Remove .dep_segment before overwriting it, in
2128 case it's not writable or noclobber is set.
2129 * expand.c (variable_expand_string): Cast result of pointer
2130 arithmetic to avoid a warning.
2131 * main.c (switches): Add full-fledged final initializer.
2133 2005-07-06 Paul D. Smith <psmith@gnu.org>
2135 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2136 * signame.c (strsignal): If we found _sys_siglist[] or
2137 __sys_siglist[] use those instead of sys_siglist[].
2138 From Albert Chin <china@thewrittenword.com>
2140 2005-07-04 Paul D. Smith <psmith@gnu.org>
2142 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2143 globfree(); set up to use the GNU versions.
2144 From Martin Zinser <zinser@zinser.no-ip.info>
2146 2005-07-03 Paul D. Smith <psmith@gnu.org>
2148 From J. Grant <jg@jguk.org>:
2150 * README.W32.template: Update the Windows and tested MSVC versions.
2151 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2152 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2153 * build_w32.bat: Ditto.
2154 * w32/subproc/build.bat: Ditto.
2156 2005-06-28 Paul D. Smith <psmith@gnu.org>
2158 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2159 declaration was checked but not present.
2161 2005-06-27 Paul D. Smith <psmith@gnu.org>
2163 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2164 to unsigned long. Fixes Savannah bug #13550.
2166 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2167 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2168 Fixes Savannah bug #13551.
2170 2005-06-26 Paul D. Smith <psmith@gnu.org>
2172 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2173 it if ANSI_STRING is not set.
2175 2005-06-25 Paul D. Smith <psmith@gnu.org>
2177 * read.c (eval): If no filenames are passed to any of the
2178 "include" variants, don't print an error.
2179 * doc/make.texi (Include): Document this.
2180 Fixes Savannah bug #1761.
2182 * job.c (construct_command_argv_internal): Sanitize handling of
2183 backslash/newline pairs according to POSIX: that is, keep the
2184 backslash-newline in the command script, but remove a following
2185 TAB character, if present. In the fast path, make sure that the
2186 behavior matches what the shell would do both inside and outside
2187 of quotes. In the slow path, quote the backslash and put a
2188 literal newline in the string.
2189 Fixes Savannah bug #1332.
2190 * doc/make.texi (Execution): Document the new behavior and give
2192 * NEWS: Make a note of the new behavior.
2194 * make.h [WINDOWS32]: #include <direct.h>.
2195 Fixes Savannah bug #13478.
2197 * remake.c (name_mtime): If the stat() of a file fails and the -L
2198 option was given and the file is a symlink, take the best mtime of
2199 the symlink we can get as the mtime of the file and don't fail.
2200 Fixes Savannah bug #13280.
2202 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2203 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2204 inside a variable reference. Make this function static as it's
2206 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2207 parsing an unexpanded line looking for semicolons.
2208 Fixes Savannah bug #1454.
2209 * misc.c (remove_comments): Move this to read.c and make it static
2210 as it's only used there. Call find_char_unquote() with new arg.
2211 * make.h: Remove prototypes for find_char_unquote() and
2212 remove_comments() since they're static now.
2214 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2215 its export flag and obtain its value. When we need to re-exec,
2216 increment the value and add it into the environment.
2217 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2218 * NEWS: Mention MAKE_RESTARTS.
2219 * main.c (always_make_set): New variable. Change the -B option to
2220 set this one instead.
2221 (main): When checking makefiles, only set always_make_flag if
2222 always_make_set is set AND the restarts flag is 0. When building
2223 normal targets, set it IFF always_make_set is set.
2224 (main): Avoid infinite recursion with -W, too: only set what-if
2225 files to NEW before we check makefiles if we've never restarted
2226 before. If we have restarted, set what-if files to NEW _after_ we
2228 Fixes Savannah bug #7566:
2230 2005-06-17 Paul D. Smith <psmith@gnu.org>
2232 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2233 in the prerequisites list.
2235 2005-06-12 Paul D. Smith <psmith@gnu.org>
2237 Fix Savannah bug # 1328.
2239 * configure.in: Check for atexit().
2240 * misc.c (close_stdout): Test stdout to see if writes to it have
2241 failed. If so, be sure to exit with a non-0 error code. Based on
2242 code found in gnulib.
2243 * make.h: Prototype.
2244 * main.c (main): Install close_stdout() with atexit().
2246 2005-06-10 Paul D. Smith <psmith@gnu.org>
2248 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2250 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2251 headers; make vmsWaitForChildren() static; extern vmsify().
2252 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2253 Don't create child_execute_job() here (it's in vmsjobs.c).
2254 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2256 2005-06-09 Paul D. Smith <psmith@gnu.org>
2258 * variable.c (push_new_variable_scope): File variables point
2259 directly to the global_setlist variable. So, inserting a new
2260 scope in front of that has no effect on those variables: they
2261 don't go through current_variable_set_list. If we're pushing a
2262 scope and the current scope is global, push it "the other way" so
2263 that the new setlist is in the global_setlist variable, and
2264 next points to a new setlist with the global variable set.
2265 (pop_variable_scope): Properly undo a push with the new
2267 Fixes Savannah bug #11913.
2269 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2271 * job.c (reap_children): Don't die of the command failed but
2272 the dontcare flag is set. Fixes Savannah bug #13216.
2274 * implicit.c (pattern_search): When creating a target from
2275 an implicit rule match, lookup pattern target and set precious
2276 flag in a newly created target. Fixes Savannah bug #13218.
2278 2005-05-13 Paul D. Smith <psmith@gnu.org>
2280 Implement "if... else if... endif" syntax.
2282 * read.c (eval): Push all checks for conditional words ("ifeq",
2283 "else", etc.) down into the conditional_line() function.
2284 (conditional_line): Rework to allow "else if..." clause. New
2285 return value -2 for lines which are not conditionals. The
2286 ignoring flag can now also be 2, which means "already parsed a
2287 true branch". If that value is seen no other branch of this
2288 conditional can be considered true. In the else parsing if there
2289 is extra text after the else, invoke conditional_line()
2290 recursively to see if it's another conditional. If not, it's an
2291 error. If so, raise the conditional value to this level instead
2292 of creating a new conditional nesting level. Special check for
2293 "else" and "endif", which aren't allowed on the "else" line.
2294 * doc/make.texi (Conditional Syntax): Document the new syntax.
2296 2005-05-09 Paul D. Smith <psmith@gnu.org>
2298 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2299 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2300 recurses to the w32 directory, even on non-Windows systems. Use
2301 the method suggested in the automake manual.
2302 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2303 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2305 2005-05-07 Paul D. Smith <psmith@gnu.org>
2307 * main.c (die): If we're dying with a fatal error (not that a
2308 command has failed), write back any leftover tokens before we go.
2310 * job.c (set_child_handler_action_flags): If there are jobs
2311 waiting for the load to go down, set an alarm to go off in 1
2312 second. This allows us to wake up from a potentially long-lasting
2313 read() and start a new job if the load has gone down. Turn it off
2315 (job_noop): Dummy signal handler function.
2316 (new_job): Invoke it with the new semantics.
2318 * docs/make.texi: Document secondary expansion. Various cleanups
2321 2005-05-03 Paul D. Smith <psmith@gnu.org>
2323 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2324 the targets which are to ultimately be made are called "goals";
2325 see the GNU make manual. Also, MAKECMDGOALS, etc.
2327 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2328 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2329 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2331 2005-05-02 Paul D. Smith <psmith@gnu.org>
2333 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2334 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2335 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2336 functions to vmsjobs.c. #include it into jobs.c.
2338 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2339 jobserver tokens. I found that this happens when an exported
2340 recursive variable contains a $(shell ...) function reference: in
2341 this situation we could "forget" to write back a token.
2343 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2344 we have. It's not reliable to depend on the number of children in
2345 our linked list so keep a separate count.
2346 (new_job): Check jobserver_tokens rather than children &&
2347 waiting_jobs. Increment jobserver_tokens when we get one.
2348 (free_child): If jobserver_tokens is 0, internal error. If it's
2349 >1, write a token back to the jobserver pipe (we don't write a
2350 token for the "free" job). Decrement jobserver_tokens.
2352 * main.c: Add variable master_job_slots.
2353 (main): Set it to hold the number of jobs requested if we're the
2354 master process, when using the jobserver.
2355 (die): Sanity checks: first test jobserver_tokens to make sure
2356 this process isn't holding any tokens we didn't write back.
2357 Second, if master_job_slots is set count the tokens left in the
2358 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2360 2005-04-24 Paul D. Smith <psmith@gnu.org>
2362 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2363 with -l# can lose jobserver tokens, because waiting jobs are not
2364 consulted properly when checking for the "free" token.
2366 * job.c (free_child): Count waiting_jobs as having tokens.
2367 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2368 handle jobs waiting for the load to drop.
2370 2005-04-23 Paul D. Smith <psmith@gnu.org>
2372 * main.c (main): Be careful to not core if a variable setting in
2373 the environment doesn't contain an '='. This is illegal but can
2374 happen in broken setups.
2375 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2377 2005-04-12 Paul D. Smith <psmith@gnu.org>
2379 The second expansion feature causes significant slowdown. Timing
2380 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2381 read the makefile before the feature, to 11+s to do the same
2382 operations after the feature. Additionally, memory usage
2383 increased drastically. To fix this I added some intelligence that
2384 avoids the overhead of the second expansion unless it's required.
2386 * dep.h: Add a new boolean field, need_2nd_expansion.
2388 * read.c (eval): When creating the struct dep for the target,
2389 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2390 (record_files): If there's a "%" in a static pattern rule, it gets
2391 converted to "$*" so set need_2nd_expansion to 1.
2393 * file.c (expand_deps): Rework to be more efficient. Only perform
2394 initialize_file_variables(), set_file_variables(), and
2395 variable_expand_for_file() if the need_2nd_expansion is set.
2397 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2398 (pattern_search): Ditto.
2399 * main.c (handle_non_switch_argument): Ditto.
2401 * read.c (read_all_makefiles): Ditto.
2402 (eval_makefile): Ditto.
2404 2005-04-07 Paul D. Smith <psmith@gnu.org>
2406 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2407 * variable.c (sync_Path_environment): Ditto.
2408 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2410 * main.c (main): Define the .FEATURES variable.
2411 * NEWS: Announce .FEATURES.
2412 * doc/make.texi (Special Variables): Document .FEATURES.
2414 * remake.c (check_dep): If a file is .PHONY, update it even if
2415 it's marked intermediate. Fixes Savannah bug #12331.
2417 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2419 * file.c (expand_deps): Factor out the second expansion and
2420 prerequisite line parsing logic from snap_deps().
2422 * file.c (snap_deps): Use expand_deps(). Expand and parse
2423 prerequisites of the .SUFFIXES special target first. Fixes
2424 Savannah bug #12320.
2426 2005-03-13 Paul D. Smith <psmith@gnu.org>
2428 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2431 2005-03-11 Paul D. Smith <psmith@gnu.org>
2433 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2434 available, not undefined (from Earnie Boyd).
2436 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2438 * implicit.c (pattern_search): Mark an intermediate target as
2439 precious if it happened to be a prerequisite of some (other)
2440 target. Fixes Savannah bug #12267.
2442 2005-03-09 Paul D. Smith <psmith@gnu.org>
2444 * read.c (eval_makefile): Add alloca(0).
2445 (eval_buffer): Ditto.
2447 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2449 * main.c (main): Use o_file instead of o_default when defining
2450 the .DEFAULT_TARGET special variable.
2451 * read.c (eval): Use define_variable_global() instead of
2452 define_variable() when setting new value for the .DEFAULT_TARGET
2453 special variable. Fixes Savannah bug #12266.
2455 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2457 * imlicit.c (pattern_search): Mark files for which an implicit
2458 rule has been found as targets. Fixes Savannah bug #12202.
2460 2005-03-04 Paul D. Smith <psmith@gnu.org>
2463 * doc/make.texi (Automatic Variables): Document $|.
2465 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2467 * read.c (record_files): Instead of substituting % with
2468 actual stem value in dependency list replace it with $*.
2469 This fixes stem triple expansion bug.
2471 * implicit.c (pattern_search): Copy stem to a separate
2472 buffer and make it a properly terminated string. Assign
2473 this buffer instead of STEM (which is not terminated) to
2474 f->stem. Instead of substituting % with actual stem value
2475 in dependency list replace it with $*. This fixes stem
2476 triple expansion bug.
2478 2005-03-01 Paul D. Smith <psmith@gnu.org>
2480 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2481 on Windows, as it takes a handle not a pid. Just exit.
2482 Fix from patch #3679, provided by Alessandro Vesely.
2484 * configure.in: Update check for sys_siglist[] from autoconf manual.
2485 * signame.c (strsignal): Update to use the new autoconf macro.
2487 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2489 * read.c (record_files): Add a check for the list of prerequisites
2490 of a static pattern rule being empty. Fixes Savannah bug #12180.
2492 2005-02-28 Paul D. Smith <psmith@gnu.org>
2494 * doc/make.texi (Text Functions): Update docs to allow the end
2495 ordinal for $(wordlist ...) to be 0.
2496 * function.c (func_wordlist): Fail if the start ordinal for
2497 $(wordlist ...) is <1. Matches documentation.
2498 Resolves Savannah support request #103195.
2500 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2501 previously we were stopping when !-q, exactly the opposite. This
2502 has been wrong since version 1.34, in 1994!
2503 (update_file): If we got an error don't break out to run more
2504 double-colon rules: just return immediately.
2505 Fixes Savannah bug #7144.
2507 2005-02-27 Paul D. Smith <psmith@gnu.org>
2509 * misc.c (end_of_token): Make argument const.
2510 * make.h: Update prototype.
2512 * function.c (abspath, func_realpath, func_abspath): Use
2513 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2514 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2515 * read.c (record_files): Ditto.
2516 * variable.c (do_variable_definition): Ditto.
2518 * function.c (func_error): Create a new function $(info ...) that
2519 simply prints the message to stdout with no extras.
2520 (function_table_init): Add new function to the table.
2521 * NEWS: Add $(info ...) reference.
2522 * doc/make.texi (Make Control Functions): Document it.
2524 New feature: if the system supports symbolic links, and the user
2525 provides the -L/--check-symlink-time flag, then use the latest
2526 mtime between the symlink(s) and the target file.
2528 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2529 readlink(). If both are available, define MAKE_SYMLINKS.
2530 * main.c: New variable: check_symlink_flag.
2531 (usage): Add a line for -L/--check-symlink-times to the help string.
2532 (switches): Add -L/--check-symlink-times command line argument.
2533 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2534 print a warning and disable it again.
2535 * make.h: Declare check_symlink_flag.
2536 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2537 if the file is a symlink then check each link in the chain and
2538 choose the NEWEST mtime we find as the mtime for the file. The
2539 newest mtime might be the file itself!
2540 * NEWS: Add information about this new feature.
2541 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2543 Avoid core dumps described in Savannah bug # 12124:
2545 * file.c: New variable snapped_deps remember whether we've run
2547 (snap_deps): Set it.
2548 * filedef.h: Extern it.
2549 * read.c (record_files): Check snapped_deps; if it's set then
2550 we're trying to eval a new target/prerequisite relationship from
2551 within a command script, which we don't support. Fatal.
2553 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2555 Implementation of the .DEFAULT_TARGET special variable.
2557 * read.c (eval): If necessary, update default_target_name when
2559 * read.c (record_files): Update default_target_file if
2560 default_target_name has changed.
2561 * main.c (default_target_name): Define.
2562 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2563 default_target_name is set use default_target_file as a root
2565 * filedef.h (default_target_name): Declare.
2566 * dep.h (free_dep_chain):
2567 * misc.c (free_dep_chain): Change to operate on struct nameseq
2568 and change name to free_ns_chain.
2569 * file.c (snap_deps): Update to use free_ns_chain.
2571 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2573 Implementation of the second expansion in explicit rules,
2574 static pattern rules and implicit rules.
2576 * read.c (eval): Refrain from chopping up rule's dependencies.
2577 Store them in a struct dep as a single dependency line. Remove
2578 the code that implements SySV-style automatic variables.
2580 * read.c (record_files): Adjust the code that handles static
2581 pattern rules to expand all percents instead of only the first
2582 one. Reverse the order in which dependencies are stored so that
2583 when the second expansion reverses them again they appear in
2584 the makefile order (with some exceptions, see comments in
2585 the code). Remove the code that implements SySV-style automatic
2588 * file.c (snap_deps): Implement the second expansion and chopping
2589 of dependency lines for explicit rules.
2591 * implicit.c (struct idep): Define an auxiliary data type to hold
2592 implicit rule's dependencies after stem substitution and
2595 * implicit.c (free_idep_chain): Implement.
2597 * implicit.c (get_next_word): Implement helper function for
2598 parsing implicit rule's dependency lines into words taking
2599 into account variable expansion requests. Used in the stem
2602 * implicit.c (pattern_search): Implement the second expansion
2603 for implicit rules. Also fixes bug #12091.
2605 * commands.h (set_file_variables): Declare.
2606 * commands.c (set_file_variables): Remove static specifier.
2608 * dep.h (free_dep_chain): Declare.
2609 * misc.c (free_dep_chain): Implement.
2611 * variable.h (variable_expand_for_file): Declare.
2612 * expand.c (variable_expand_for_file): Remove static specifier.
2614 * make.h (strip_whitespace): Declare.
2615 * function.c (strip_whitespace): Remove static specifier.
2617 2005-02-26 Paul D. Smith <psmith@gnu.org>
2619 * main.c (main): Check for ferror() when reading makefiles from stdin.
2620 Apparently some shells in Windows don't close pipes properly and
2623 2005-02-24 Jonathan Grant <jg@jguk.org>
2625 * configure.in: Add MinGW configuration options, and extra w32 code
2627 * Makefile.am: Add MinGW configuration options, and extra w32 code
2629 * main.c: Determine correct program string (after last \ without .exe).
2630 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2632 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2633 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2634 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2635 environment support.
2637 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2639 * function.c (func_shell): When initializing error_prefix, check
2640 that reading file name is not null. This fixes long-standing
2641 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2643 2005-02-09 Paul D. Smith <psmith@gnu.org>
2645 * maintMakefile: Update the CVS download URL to simplify them.
2646 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2647 downloading the .texi files from Savannah now.
2649 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2651 * main.c (handle_non_switch_argument): Only add variables to
2652 command_variables if they're not already there: duplicate settings
2653 waste space and can be confusing to read.
2655 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2656 this header is never included by non-WINDOWS32 code, and it
2657 requires <config.h> to define which isn't always included first.
2659 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2660 testing MINGW32 versions.
2662 * main.c (log_working_directory): flush stdout to be sure the WD
2663 change is printed before any stderr messages show up.
2665 2005-02-01 Paul D. Smith <psmith@gnu.org>
2667 * maintMakefile (po_repo): Update the GNU translation site URL.
2669 2004-12-01 Paul D. Smith <psmith@gnu.org>
2671 * main.c (main): Change char* env_shell to struct variable shell_var.
2672 * variable.c (target_environment): Use new shell_var.
2674 2004-11-30 Paul D. Smith <psmith@gnu.org>
2676 * configure.in: The old way we avoided creating build.sh from
2677 build.sh.in before build.sh.in exists doesn't work anymore; we
2678 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2679 the help!). This also keeps automake from complaining.
2680 * Makefile.am (README): Add a dummy target so automake won't
2681 complain that this file doesn't exist when we checkout from CVS.
2682 * maintMakefile (.dep_segment): Rewrite this rule since newer
2683 versions of automake don't provide DEP_FILES.
2685 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2687 Implementation of `realpath' and `abspath' built-in functions.
2689 * configure.in: Check for realpath.
2690 * function.c (abspath): Return an absolute file name that does
2691 not contain any `.' or `..' components, nor repeated `/'.
2692 * function.c (func_abspath): For each name call abspath.
2693 * function.c (func_realpath): For each name call realpath
2694 from libc or delegate to abspath if realpath is not available.
2695 * doc/make.texi (Functions for File Names): Document new functions.
2696 * doc/make.texi (Quick Reference): Ditto.
2698 2004-11-28 Paul D. Smith <psmith@gnu.org>
2700 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2701 arguments. Fixes bug #10252.
2703 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2705 * main.c (main): Set SHELL to v_noexport by default. Remember the
2706 original environment setting of SHELL in the env_shell variable.
2707 * main.h: Export new env_shell variable.
2708 * variable.c (target_environment): If we find a v_noexport
2709 variable for SHELL, add a SHELL variable with the env_shell value.
2710 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2711 * doc/make.texi (Variables/Recursion): Ditto.
2713 2004-11-28 Paul D. Smith <psmith@gnu.org>
2715 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2716 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2717 Patch by Alessandro Vesely.
2719 2004-11-12 Paul D. Smith <psmith@gnu.org>
2721 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2722 the command line if it's inside a string.
2723 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2725 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2727 * function.c (func_lastword): New function: return last word
2728 from the list of words.
2729 * doc/make.texi: Document $(lastword ). Fix broken links in
2730 Quick Reference section.
2732 2004-10-06 Paul D. Smith <psmith@gnu.org>
2734 Apply patch from Alessandro Vesely, provided with bug # 9748.
2735 Fix use of tmpnam() to work with Borland C.
2737 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2738 construction of a temporary filename, and call new function
2739 create_batch_filename().
2740 (create_batch_filename) [WINDOWS32]: New function to create a
2743 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2745 * read.c (record_target_var): Expand simple pattern-specific
2747 * variable.c (initialize_file_variables): Do not expand simple
2748 pattern-specific variable.
2750 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2752 * remake.c (update_file_1): When rebuilding makefiles inherit
2753 dontcare flag from a target that triggered update.
2755 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2757 * variable.c (initialize_file_variables): Mark pattern-specific
2758 variable as a per-target and copy export status.
2760 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2762 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2764 * implicit.c (pattern_search): When considering an implicit rule's
2765 prerequisite check that it is actually a target rather then
2766 just an entry in the file hashtable.
2768 2004-09-21 Paul D. Smith <psmith@gnu.org>
2770 * read.c (readstring): Fix some logic errors in backslash handling.
2771 (eval): Remove some unnecessary processing in buffer handling.
2772 (record_target_var): Assert that parse_variable_definition() succeeded.
2773 Reported by: Markus Mauhart <qwe123@chello.at>.
2775 * misc.c: Removed the sindex() function. All instances of this
2776 function were trivially replaceable by the standard strstr()
2777 function, and that function will always have better (or certainly
2778 no worse) performance than the very simple-minded algorithm
2779 sindex() used. This can matter with complex makefiles.
2780 * make.h: Remove the prototype for sindex().
2781 * function.c (subst_expand): Convert sindex() call to strstr().
2782 This means we no longer need to track the TLEN value so remove that.
2783 (func_findstring): Convert sindex() to strstr().
2784 * commands.c (chop_commands): Convert sindex() calls to strstr().
2785 Suggested by: Markus Mauhart <qwe123@chello.at>.
2787 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2788 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2789 If SHELL is set to CMD.EXE then assume it's batch-mode and
2790 non-unixy. I wrote the code differently from the patch, though,
2791 to make it safer. This also resolves bug #9174.
2793 2004-09-20 Paul D. Smith <psmith@gnu.org>
2795 * expand.c (variable_expand_string): Modify to invoke
2796 patsubst_expand() instead of subst_expand(); the latter didn't
2797 handle suffix patterns correctly.
2798 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2799 was used only from variable_expand_string() and is no longer used
2801 (func_subst): Ditto, on call to subst_expand().
2802 (patsubst_expand): Require the percent pointers to point to the
2803 character after the %, not to the % itself.
2804 * read.c (record_files): New call criteria for patsubst_expand().
2805 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2806 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2808 2004-09-19 Paul D. Smith <psmith@gnu.org>
2810 * function.c (subst_expand): Fix a check in by_word: look for a
2811 previous blank if we're beyond the beginning of the string, not
2812 the beginning of the word.
2813 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2815 2004-05-16 Paul D. Smith <psmith@gnu.org>
2817 * remake.c (update_goal_chain): Change the argument specifying
2818 whether we're rebuilding makefiles to be a global variable,
2819 REBUILDING_MAKEFILES.
2820 (complain): Extract the code that complains about no rules to make
2821 a target into a separate function.
2822 (update_file_1): If we tried to rebuild a file during the makefile
2823 rebuild phase and it was dontcare, then no message was printed.
2824 If we then try to build the same file during the normal build,
2825 print a message this time.
2826 (remake_file): Don't complain about un-remake-able files when
2827 we're rebuilding makefiles.
2829 2004-05-11 Paul D. Smith <psmith@gnu.org>
2831 * job.c (construct_command_argv_internal): OS/2 patches from
2832 Andreas Buening <andreas.buening@nexgo.de>.
2834 2004-05-10 Paul D. Smith <psmith@gnu.org>
2836 * remake.c (update_file): Don't walk the double-colon chain unless
2837 this is a double-colon rule. Fix suggested by Boris Kolpackov
2838 <boris@kolpackov.net>.
2840 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2841 * readme.vms: New section describing OpenVMS support and issues.
2842 * default.c (default_variables): Add support for IA64.
2843 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2844 without some privilege aborts make with the error
2845 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2846 pressing Ctrl+Y and the input device is no terminal. The change
2847 catches this error and just continues.
2849 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2851 2004-04-25 Paul D. Smith <psmith@gnu.org>
2853 * commands.c (set_file_variables): Set $< properly in the face of
2854 order-only prerequisites.
2855 Patch from Boris Kolpackov <boris@kolpackov.net>
2857 2004-04-21 Bob Byrnes <byrnes@curl.com>
2859 * main.c (main): Notice failures to remake makefiles.
2861 2004-03-28 Paul D. Smith <psmith@gnu.org>
2863 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2865 * job.c: No default shell for RISC OS.
2866 (load_too_high): Hard-code the return to 1.
2867 (construct_command_argv_internal): No sh_chars or sh_cmds.
2868 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2870 2004-03-20 Paul D. Smith <psmith@gnu.org>
2872 * variable.c (do_variable_definition): Don't append from the
2873 global set if a previous non-appending target-specific variable
2874 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2877 * expand.c (reference_variable): Don't give up on variables with
2878 no value that have the target-specific append flag set: they might
2879 have a value after all. Reported by Oliver Schmidt
2880 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2881 <nikulin@dx1cmd.inp.nsk.su>.
2883 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2884 refer to absolute pathnames in directories that don't exist: some
2885 portion of the makefile could create those directories before we
2886 match the pattern. Fixes bugs #775 and #108.
2888 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2890 * main.c (main): Free makefile_mtimes if we have any.
2891 * README.W32.template: Update documentation for the current status
2892 of the MS-Windows port.
2893 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2894 environment variable is sometimes already defined which causes the
2896 * main.c (debug_signal_handler): Only define this function if
2897 SIGUSR1 is available.
2899 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2901 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2902 * README.OS2.template: Documentation updates.
2903 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2904 link line for safety.
2905 * maintMakefile (build.sh.in): Remove an extraneous ")".
2906 * job.c (child_execute_job): Close saved FDs.
2907 * job.c (exec_command) [OS/2]: exec_command(): If the command
2908 can't be exec'ed and if the shell is not Unix-sh, then try again
2909 with argv = { "cmd", "/c", ... }. Normally, this code is never
2910 reached for the cmd shell unless the command really doesn't exist.
2911 (construct_command_argv_internal) [OS/2]: The code for cmd
2912 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2913 The CMD builtin commands are case insensitive so use strcasecmp().
2915 2004-03-19 Paul D. Smith <psmith@gnu.org>
2917 * read.c (do_define): Re-order line counter increment so the count
2918 is accurate (we were losing one line per define). Reported by
2919 Dave Yost <Dave@Yost.com>.
2921 2004-03-06 Paul D. Smith <psmith@gnu.org>
2923 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2925 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2926 * misc.c (message,error,fatal): Ditto.
2927 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2928 * config.h.W32.template: Ditto.
2929 * config.h-vms.template: Ditto.
2930 * config.ami.template: Ditto.
2932 2004-03-04 Paul D. Smith <psmith@gnu.org>
2934 * README.template: Add a note about broken /bin/sh on SunOS
2935 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2937 * misc.c (message, error, fatal): Don't use "..." if we're using
2938 varargs. ansi2knr should handle this but it doesn't work: it
2939 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2940 done. On many systems (SunOS for example) va_dcl is a #define.
2941 So, force the use of the non-"..." version on pre-ANSI compilers.
2943 * maintMakefile (sign-dist): Create some rules to help automate
2944 the new GNU ftp upload method.
2946 2004-02-24 Paul D. Smith <psmith@gnu.org>
2948 * config.h.W32.template: Add HAVE_STDARG_H
2949 * config.h-vms.template: Ditto.
2950 * config.ami.template: Ditto.
2952 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2954 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2955 * build_w32.bat: Remove extra "+".
2957 2004-02-23 Paul D. Smith <psmith@gnu.org>
2959 * make.h: Create an UNUSED macro to mark unused parameters.
2960 * (many): Clean up warnings by applying UNUSED, fixing
2961 signed/unsigned incompatibilities, etc.
2963 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2965 * filedef.h: Name the command_state enumeration.
2966 * file.c (set_command_state): Use the enumeration in the function
2969 * configure.in: Explicitly set SET_MAKE to empty, to disable
2970 MAKE=make even when no make already exists. Fix bug #3823.
2972 2004-02-22 Paul D. Smith <psmith@gnu.org>
2974 * maintMakefile: Perl script to clean up all non-CVS files. Use
2975 it on all the subdirectories for the cvs-clean target.
2977 * main.c (decode_switches): Require non-empty strings for all our
2978 string command-line options. Fixes Debian bug # 164165.
2980 * configure.in: Check for stdarg.h and varargs.h.
2981 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2982 for printing messages.
2983 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2988 A number of patches for OS/2 support from Andreas Buening
2989 <andreas.buening@nexgo.de>:
2991 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2992 disable the SIGCHLD handler.
2993 (reap_children) [OS/2]: Remove special handling of job_rfd.
2994 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2995 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2996 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2997 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2998 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3001 2004-02-21 Paul D. Smith <psmith@gnu.org>
3003 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3004 <mail@kristov.de> reports that if process_begin() fails we don't
3005 handle the error condition correctly in all cases.
3006 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3007 to have a newline on the message.
3009 * job.c (construct_command_argv_internal): Add "test" to UNIX
3010 sh_cmds[]. Fixes Savannah bug # 7606.
3012 2004-02-04 Paul D. Smith <psmith@gnu.org>
3014 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3015 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3016 Hartmut Becker <Hartmut.Becker@hp.com>.
3018 2004-01-21 Paul D. Smith <psmith@gnu.org>
3020 * job.c (load_too_high): Implement an algorithm to control the
3021 "thundering herd" problem when using -l to control job creation
3022 via the load average. The system only recomputes the load once a
3023 second but we can start many jobs in a second. To solve this we
3024 keep track of the number of jobs started in the last second and
3025 apply a weight to try to guess what a correct load would be.
3026 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3027 Also fixes bug #4693.
3028 (reap_children): Decrease the job count for this second.
3029 (start_job_command): Increase the job count for this second.
3031 * read.c (conditional_line): Expand the text after ifn?def before
3032 checking to see if it's a single word. Fixes bug #7257.
3034 2004-01-09 Paul D. Smith <psmith@gnu.org>
3036 * file.c (print_file): Recurse to print all targets in
3037 double-colon rules. Fixes bug #4518, reported (with patch) by
3038 Andrew Chatham <chatham@google.com>.
3040 2004-01-07 Paul D. Smith <psmith@gnu.org>
3042 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3043 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3044 AC_FUNC_SETVBUF_REVERSED.
3046 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3047 (MAKE Variable): Fix Savannah bug #4898.
3049 * job.c (construct_command_argv_internal): Add "!" to the list of
3050 shell escape chars. POSIX sh allows it to appear before a
3051 command, to negate the exit code. Fixes bug #6404.
3053 * implicit.c (pattern_search): When matching an implicit rule,
3054 remember which dependencies have the ignore_mtime flag set.
3055 Original fix provided in Savannah patch #2349, by Benoit
3056 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3058 2003-11-22 Paul D. Smith <psmith@gnu.org>
3060 * README.W32.template (Outputs): Clarification on -j with
3061 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3064 2003-11-02 Paul D. Smith <psmith@gnu.org>
3066 * function.c (func_if): Strip all the trailing whitespace from the
3067 condition, then don't expand it. Fixed bug # 5798.
3069 * expand.c (recursively_expand_for_file): If we're expanding a
3070 variable with no file context, then use the variable's context.
3073 2003-10-21 Paul D. Smith <psmith@gnu.org>
3075 * main.c (log_working_directory): Add newlines to printf()s.
3077 * README.cvs: Add a note to ignore warnings during autoreconf.
3079 * maintMakefile (po_repo): Set a new URL for PO file updates.
3080 (get-config/config.guess get-config/config.sub): Get these files
3081 from the Savannah config project instead of ftp.gnu.org.
3083 2003-10-05 Paul Eggert <eggert@twinsun.com>
3085 * main.c (main): Avoid potential subscript error if environ has
3088 2003-08-22 Paul D. Smith <psmith@gnu.org>
3090 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3091 systems which don't yet implement the C89 standard :-/.
3093 2003-07-18 Paul D. Smith <psmith@gnu.org>
3095 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3096 [WINDOWS32]: Initialize hash.
3098 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3100 * dir.c (read_dirstream): Provide a workaround for broken versions of
3101 the MinGW dirent structure.
3103 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3105 * w32/include/dirent.h: Add __MINGW32__ filter.
3107 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3109 * make.h: Add global declaration of *make_host.
3110 * main.c (print_usage): Remove local declaration of *make_host.
3111 (print_version): Display "This program built for ..." after Copyright
3114 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3116 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3117 execution of "makeinfo --html make.texi".
3119 2003-04-30 Paul D. Smith <psmith@gnu.org>
3121 * build.template: Make some changes to maybe allow this script to
3122 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3124 * README.OS2.template: New file for OS/2 support. Original
3125 contributed by Andreas Buening.
3126 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3129 2003-04-19 Paul D. Smith <psmith@gnu.org>
3131 Fix bug #1405: allow a target to match multiple pattern-specific
3134 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3135 variable.c, where they've always belonged.
3136 * rule.h: Move the prototypes and struct pattern_var as well.
3137 * variable.c (initialize_file_variables): Invoke
3138 lookup_pattern_var() in a loop, until no more matches are found.
3139 If a match is found, create a new variable set for the target's
3140 pattern variables. Then merge the contents of each matching
3141 pattern variable set into the target's pattern variable set.
3142 (lookup_pattern_var): Change this function to be usable
3143 in a loop. It takes a starting position: if NULL, start at the
3144 beginning; if non-NULL, start with the pattern variable after that
3145 position, and return the next matching pattern.
3146 (create_pattern_var): Create a unique instance of
3147 pattern-specific variables for every definition in the makefile.
3148 Don't combine the same pattern together. This allows us to
3149 process the variable handling properly even when the same pattern
3150 is used multiple times.
3151 (parse_variable_definition): New function: break out the parsing
3152 of a variable definition line from try_variable_definition.
3153 (try_variable_definition): Call parse_variable_definition to
3155 (print_variable_data_base): Print out pattern-specific variables.
3156 * variable.h (struct variable): Remember when a variable is
3157 conditional. Also remember its flavor.
3158 (struct pattern_var): Instead of keeping a variable set, we just
3159 keep a single variable for each pattern.
3160 * read.c (record_target_var): Each pattern variable contains only a
3161 single variable, not a set, so create it properly.
3162 * doc/make.texi (Pattern-specific): Document the new behavior.
3164 2003-04-17 Paul D. Smith <psmith@gnu.org>
3166 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3167 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3168 file/directory naming rules for VMS so I can't tell whether this
3171 2003-04-09 Paul D. Smith <psmith@gnu.org>
3173 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3174 DOS-style pathnames: backslash separators and drive specifiers.
3176 2003-03-28 Paul D. Smith <psmith@gnu.org>
3178 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3179 the intermediate flag on all targets. Fixes bug #2515.
3181 2003-03-24 Paul D. Smith <psmith@gnu.org>
3183 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3184 Upgrade to autoconf 2.57 and automake 1.7.3.
3186 * job.c: More OS/2 changes from Andreas Buening.
3188 * file.c (print_file): Fix variable initialization.
3191 * remake.c (notice_finished_file):
3193 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3194 some calls (like readdir()) return NULL in valid situations
3195 without resetting errno. Fixes bug #2846.
3197 2003-02-25 Paul D. Smith <psmith@gnu.org>
3199 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3201 * job.c (_is_unixy_shell) [OS/2]: New function.
3202 Set default shell to /bin/sh.
3203 (reap_children): Close the job_rfd pipe here since we don't use a
3205 (set_child_handler_action_flags): define this to empty on OS/2.
3206 (start_job_command): Close the jobserver pipe and use
3207 child_execute_job() instead of fork/exec.
3208 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3209 rather than exec'ing, then reconfigure stdin/stdout.
3210 (exec_command): Rewrite to use spawn instead of exec. Return the
3213 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3214 in DOS. Handle the TEMP environment variable as in DOS. Don't
3215 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3216 use -j in DOS mode. Use child_execute_job() instead of
3219 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3222 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3223 prototypes that return values.
3225 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3227 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3228 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3230 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3233 2003-02-24 Paul D. Smith <psmith@gnu.org>
3235 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3236 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3237 (child_execute_job) [VMS]: Handle error status properly.
3238 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3240 * function.c (func_shell): Use EINTRLOOP() while reading from the
3241 subshell pipe (Fixes bug #2502).
3242 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3244 * main.c (main): Ditto.
3246 2003-01-30 Paul D. Smith <psmith@gnu.org>
3248 * read.c (eval): eval() was not fully reentrant, because the
3249 collapsed buffer was static. Change it to be an automatic
3250 variable so that eval() can be invoked recursively.
3252 (eval): Apply patch # 1022: fix memory reference error on long
3253 target-specific variable lines.
3254 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3256 * function.c (check_numeric): Combine the is_numeric() function
3257 into this function, since it's only called from one place.
3258 Constify this function. Have it print the incorrect string in the
3259 error message. Fixes bug #2407.
3260 (strip_whitespace): Constify.
3261 (func_if): Constify.
3262 * expand.c (expand_argument): Constify.
3264 2003-01-29 Paul D. Smith <psmith@gnu.org>
3266 Fix bug # 2169, also reported by other people on various systems.
3268 * make.h: Some systems, such as Solaris and PTX, do not fully
3269 implement POSIX-compliant SA_RESTART functionality; important
3270 system calls like stat() and readdir() can still fail with EINTR
3271 even if SA_RESTART has been set on the signal handler. So,
3272 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3273 EINTR for system calls which return -1 or 0 (NULL), respectively,
3275 Also, remove the old atomic_stat()/atomic_readdir() and
3276 HAVE_BROKEN_RESTART handling.
3278 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3280 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3281 * remake.c (touch_file): Ditto.
3283 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3284 * read.c (construct_include_path): Ditto.
3285 * remake.c (name_mtime): Ditto.
3286 * vpath.c (selective_vpath_search): Ditto.
3287 * dir.c (find_directory): Ditto.
3288 (local_stat): Ditto.
3289 (find_directory): Use ENULLLOOP() to wrap opendir().
3290 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3292 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3293 atomic_readdir() handling.
3295 2003-01-22 Paul D. Smith <psmith@gnu.org>
3297 * function.c (func_call): Fix Bug #1744. If we're inside a
3298 recursive invocation of $(call ...), mask any of the outer
3299 invocation's arguments that aren't used by this one, so that this
3300 invocation doesn't "inherit" them accidentally.
3302 2002-12-05 Paul D. Smith <psmith@gnu.org>
3304 * function.c (subst_expand): Valery Khamenia reported a
3305 pathological performance hit when doing substitutions on very
3306 large values with lots of words: turns out we were invoking
3307 strlen() a ridiculous number of times. Instead of having each
3308 call to sindex() call strlen() again, keep track of how much of
3309 the text we've seen and pass the length to sindex().
3311 2002-11-19 Paul D. Smith <psmith@gnu.org>
3313 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3316 2002-11-16 Paul D. Smith <psmith@gnu.org>
3318 * NMakefile.template (OBJS): Add hash.c object file.
3319 * SMakefile.template (srcs): Ditto.
3320 * Makefile.ami (objs): Ditto.
3321 * build_w32.bat: Ditto.
3323 * Makefile.DOS.template: Remove extra dependencies.
3325 2002-10-25 Paul D. Smith <psmith@gnu.org>
3327 * expand.c (install_variable_buffer): New function. Install a new
3328 variable_buffer context and return the previous one.
3329 (restore_variable_buffer): New function. Free the current
3330 variable_buffer context and put a previously saved one back.
3331 * variable.h: Prototypes for {install,restore}_variable_buffer.
3332 * function.c (func_eval): Push a new variable_buffer context
3333 before we eval, then restore the old one when we're done.
3336 * read.c (install_conditionals): New function. Install a new
3337 conditional context and return the previous one.
3338 (restore_conditionals): New function. Free the current
3339 conditional context and put a previously saved one back.
3340 (eval): Use the {install,restore}_conditionals for "include"
3342 (eval_buffer): Use {install,restore}_conditionals to preserve the
3343 present conditional state before we evaluate the buffer.
3346 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3348 (Recursion): Add a variable index entry for CURDIR.
3350 * README.cvs: Update to appropriate versions.
3351 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3352 don't need to copy loadavg.c: automake is smart enough to create
3353 it for me. Still have a bug in automake related to ansi2knr tho.
3355 2002-10-14 Paul D. Smith <psmith@gnu.org>
3357 * remake.c (notice_finished_file): Only touch targets if they have
3358 at least one command (as per POSIX). Resolve Bug #1418.
3360 * *.c: Convert to using ANSI C-style function definitions.
3361 * Makefile.am: Enable the ansi2knr feature of automake.
3362 * configure.in: ditto.
3364 2002-10-13 Paul D. Smith <psmith@gnu.org>
3366 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3367 for automatic variable values like $^, etc. In the case of very
3368 large lists of prerequisites this causes problems. Instead reuse
3369 a static buffer (resizeable) for each variable.
3371 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3372 target-specific variable definitions. Check for it and set an
3374 (record_target_var): Set the export field to v_export if the
3375 "exported" flag is set.
3376 * doc/make.texi (Target-specific): Document the ability to use
3379 * doc/make.texi: Change the name of the section on automatic
3380 variables from "Automatic" to "Automatic Variables". Added text
3381 clarifying the scope of automatic variables.
3383 2002-10-04 Paul D. Smith <psmith@gnu.org>
3385 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3387 (record_files): Ditto.
3389 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3390 the search for the '=' to only within the enclosing parens.
3392 2002-10-03 Paul D. Smith <psmith@gnu.org>
3394 Version 3.80 released.
3396 * dir.c: Change hash functions to use K&R function definition style.
3397 * function.c: Ditto.
3399 * variable.c: Ditto.
3401 Update to automake 1.7.
3403 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3404 (pdf): Remove this target as automake now provides one.
3406 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3408 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3410 * makefile.com: Updates for GNU make 3.80.
3411 * makefile.vms: Ditto.
3413 2002-09-23 Paul D. Smith <psmith@gnu.org>
3415 * read.c (enum make_word_type): Remove w_comment.
3416 (get_next_mword): Don't treat comment characters as special; where
3417 this function is used we will never see a comment (it's stripped
3418 before we get here) and treating comments specially means that
3419 targets like "foo\#bar" aren't handled properly.
3421 2002-09-18 Paul D. Smith <psmith@gnu.org>
3423 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3425 * read.c (eval): Expansion of arguments to export/unexport was
3426 ignoring all arguments after the first one. Change the algorithm
3427 to expand the whole line once, then parse the results.
3429 2002-09-17 Paul D. Smith <psmith@gnu.org>
3431 Fix Bug #940 (plus another bug I found while looking at this):
3433 * read.c (record_target_var): enter_file() will add a new entry if
3434 it's a double-colon target: we don't want to do that in this
3435 situation. Invoke lookup_file() and only enter_file() if it does
3436 not already exist. If the file we get back is a double-colon then
3437 add this variable to the "root" double-colon target.
3439 * variable.c (initialize_file_variables): If this file is a
3440 double-colon target but is not the "root" target, then initialize
3441 the root and make the root's variable list the parent of our
3444 2002-09-13 Paul D. Smith <psmith@gnu.org>
3446 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3448 * hash.c (round_up_2): Get rid of a warning.
3450 2002-09-12 Paul D. Smith <psmith@gnu.org>
3452 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3453 so it doesn't complain about getloadavg.c.
3455 * commands.c (set_file_variables): Make sure we always alloca() at
3456 least 1 character for the value of $? (for '\0').
3458 2002-09-11 Paul D. Smith <psmith@gnu.org>
3460 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3461 macro to use RESULT instead of the incorrect _RESULT_.
3463 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3464 and atomic_readdir(). We need to #include dirent.h to get this to
3466 * misc.c (atomic_readdir): Fix typos.
3468 2002-09-10 Paul D. Smith <psmith@gnu.org>
3470 * read.c (eval): Expand variable lists given to export and
3471 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3472 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3474 * doc/make.texi (Variables/Recursion): Document this.
3475 (Conditional Syntax): And here.
3477 2002-09-09 Paul D. Smith <psmith@gnu.org>
3479 * configure.in: Check for memmove().
3481 2002-09-07 Paul D. Smith <psmith@gnu.org>
3483 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3484 Michael Sterrett <msterret@coat.com> reports that while it has
3485 SA_RESTART, it does not work properly.
3487 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3488 that invokes stat() and loops to do it again if it returns EINTR.
3489 (atomic_readdir): Ditto, with readdir().
3491 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3492 and readdir() to atomic_stat() and atomic_readdir().
3494 2002-09-04 Paul D. Smith <psmith@gnu.org>
3496 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3497 reports that GNU make sometimes doesn't recognize that targets can
3498 be made, when directories can be created as prerequisites. He
3499 reports that changing the order of predicates in the DEP->changed
3500 flag test so that lookup_file() is always performed, solves this
3503 2002-08-08 Paul D. Smith <psmith@gnu.org>
3505 * configure.in: Require a newer version of gettext.
3507 * misc.c (perror_with_name): Translate the format string (for
3508 right-to-left language support).
3509 (pfatal_with_name): Ditto.
3511 * main.c: Create a static array of strings to store the usage
3512 text. This is done to facilitate translations.
3513 (struct command_switch): Remove argdesc and description fields.
3514 (switches): Remove values for obsolete fields.
3515 (print_usage): Print each element of the usage array.
3517 * hash.c: Change function definitions to be K&R style.
3519 2002-08-02 Paul D. Smith <psmith@gnu.org>
3521 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3522 this one because it's too hard to get right. We'll look at it for
3524 * main.c (main): Don't create the .TARGETS variable.
3525 * variable.c (handle_special_var): Don't handle .TARGETS.
3527 2002-08-01 Paul D. Smith <psmith@gnu.org>
3529 * main.c (switches): Add a new option, -B (--always-make). If
3530 specified, make will rebuild all targets that it encounters even
3531 if they don't appear to be out of date.
3532 (always_make_flag): New flag.
3533 * make.h: Extern always_make_flag.
3534 * remake.c (update_file_1): Check always_make_flag; if it's set we
3535 will always rebuild any target we can, even if none of its
3536 prerequisites are newer.
3539 * doc/make.texi (Shell Function): Make it clear that make
3540 variables marked as "export" are not passed to instances of the
3543 Add new introspection variable .VARIABLES and .TARGETS.
3545 * variable.c (handle_special_var): New function. If the variable
3546 reference passed in is "special" (.VARIABLES or .TARGETS),
3547 calculate the new value if necessary. .VARIABLES is handled here:
3548 walk through the hash of defined variables and construct a value
3549 which is a list of the names. .TARGETS is handled by
3550 build_target_list().
3551 (lookup_variable): Invoke handle_special_var().
3552 * file.c (build_target_list): Walk through the hask of known files
3553 and construct a list of the names of all the ones marked as
3555 * main.c (main): Initialize them to empty (and as simple variables).
3556 * doc/make.texi (Special Variables): Document them.
3557 * NEWS: Mention them.
3559 * variable.h (struct variable): Add a new flag "exportable" which
3560 is true if the variable name is valid for export.
3561 * variable.c (define_variable_in_set): Set "exportable" when a new
3562 variable is defined.
3563 (target_environment): Use the "exportable" flag instead of
3564 re-checking the name here... an efficiency improvement.
3566 2002-07-31 Paul D. Smith <psmith@gnu.org>
3568 * config.h-vms.template: Updates to build on VMS. Thanks to
3569 Brian_Benning@aksteel.com for helping verify the build.
3570 * makefile.com: Build the new hash.c file.
3571 * hash.h: Use strcpmi(), not stricmp(), in the
3572 HAVE_CASE_INSENSITIVE_FS case.
3574 2002-07-30 Paul D. Smith <psmith@gnu.org>
3576 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3577 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3578 Reported by <Brian_Benning@aksteel.com>.
3580 2002-07-10 Paul D. Smith <psmith@gnu.org>
3582 * variable.c (pop_variable_scope): Remove variable made unused by
3583 new hash infrastructure.
3584 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3585 comparisons as well as name comparisons.
3586 * variable.h: Add a prototype for new hash_init_function_table().
3587 * file.c (lookup_file): Remove variables made unused by new hash
3589 * dir.c (directory_contents_hash_2): Missing return of hash value.
3590 (dir_contents_file_exists_p): Remove variables made unused by new
3591 hash infrastructure.
3594 Installed Greg McGary's integration of the hash functions from the
3595 GNU id-utils package:
3597 2002-07-10 Greg McGary <greg@mcgary.org>
3599 * scripts/functions/filter-out: Add literals to to the
3600 pattern space in order to add complexity, and trigger
3601 use of an internal hash table. Fix documentation strings.
3602 * scripts/targets/INTERMEDIATE: Reverse order of files
3603 passed to expected `rm' command.
3605 2002-07-10 Greg McGary <greg@mcgary.org>
3607 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3608 * hash.c: New file, taken from id-utils.
3609 * hash.h: New file, taken from id-utils.
3611 * make.h (HASH, HASHI): Remove macros.
3612 (find_char_unquote): Change arglist in decl.
3613 (hash_init_directories): New function decl.
3614 * variable.h (hash.h): New #include.
3615 (MAKELEVEL_NAME, MAKELEVEL_LENGTH): New constants.
3616 * filedef.h (hash.h): New #include.
3617 (struct file) [next]: Remove member.
3618 (file_hash_enter): Remove function decl.

3621 * ar.c (ar_name): Delay call to strlen until needed.
3622 * main.c (initialize_global_hash_tables): New function.
3623 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3624 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3625 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.

3664 (struct a_pattern): New struct.
3665 (func_filter_filterout): Pass through patterns noting boundaries
3666 and '%', if present. Note a_word length. Use a hash table if
3667 arglists are large enough to justify cost.
3668 (function_table_init): Renamed from function_table.

3677 (find_char_unquote): Accept two char-constant stop chars, rather
3678 than a string constant, avoiding zillions of calls to strchr.
3679 Tighten inner search loops to test only for desired delimiters.

3697 2002-07-10 Paul D. Smith <psmith@gnu.org>
3699 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3700 prerequisite list. A real SysV make will expand the entire
3701 prerequisites list _twice_: we don't do that as it's a big
3702 backward-compatibility problem. We only replace those specific
3705 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3706 references left in the list of prerequisites. Check for .POSIX as
3707 we record targets, so we can disable non-POSIX behavior while
3708 reading makefiles as well as running them.
3709 (eval): Check the prerequisite list to see if we have anything
3710 that looks like a SysV prerequisite variable reference.
3712 2002-07-09 Paul D. Smith <psmith@gnu.org>
3714 * doc/make.texi (Prerequisite Types): Add a new section describing
3715 order-only prerequisites.
3717 * read.c (uniquize_deps): If we have the same file as both a
3718 normal and order-only prereq, get rid of the order-only prereq,
3719 since the normal one supersedes it.
3721 2002-07-08 Paul D. Smith <psmith@gnu.org>
3723 * AUTHORS: Added Greg McGary to the AUTHORS file.
3724 * NEWS: Blurbed order-only prerequisites.
3725 * file.c (print_file): Show order-only deps properly when printing
3728 * maintMakefile: Add "update" targets for wget'ing the latest
3729 versions of various external files. Taken from Makefile.maint in
3732 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3733 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3735 2002-07-07 Paul D. Smith <psmith@gnu.org>
3737 * po/*.po: Remove. We'll use wget to retrieve them at release
3740 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3741 rather than a shell you get an exception. Make sure we look up
3742 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3744 * remake.c (notice_finished_file): Fix handling of -t flag.
3745 Patch provided by Henning Makholm <henning@makholm.net>.
3747 * implicit.c (pattern_search): Some systems apparently run short
3748 of stack space, and using alloca() in this function caused an
3749 overrun. I modified it to use xmalloc() on the two variables
3750 which seemed like they might get large. Fixes Bug #476.
3752 * main.c (print_version): Update copyright notice to conform with
3754 (print_usage): Update help output.
3756 * function.c (func_eval): Create a new make function, $(eval
3757 ...). Expand the arguments, put them into a buffer, then invoke
3758 eval_buffer() on the resulting string.
3759 (func_quote): Create a new function, $(quote VARNAME). Inserts
3760 the value of the variable VARNAME without expanding it any
3763 * read.c (struct ebuffer): Change the linebuffer structure to an
3764 "eval buffer", which can be either a file or a buffer.
3765 (eval_makefile): Move the code in the old read_makefile() which
3766 located a makefile into here: create a struct ebuffer with that
3767 information. Have it invoke the new function eval() with that
3769 (eval_buffer): Create a new function that creates a struct ebuffer
3770 that holds a string buffer instead of a file. Have it invoke
3771 eval() with that ebuffer.
3772 (eval): New function that contains the guts of the old
3773 read_makefile() function: this function parses makefiles. Obtains
3774 data to parse from the provided ebuffer. Some modifications to
3775 make the flow of the function cleaner and clearer. Still could
3776 use some work here...
3777 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3778 contents of the define/endef variable from the ebuffer.
3779 (readstring): Read the next line from a string-style ebuffer.
3780 (readline): Read the next line from an ebuffer. If it's a string
3781 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3784 * dep.h (eval_buffer): Prototype eval_buffer();
3786 * variable.c (do_variable_definition): Make sure that all
3787 non-target-specific variables are registered in the global set.
3788 If we're invoked from an $(eval ...) we might be inside a $(call
3789 ...) or other function which has pushed a variable scope; we still
3790 want to define our variables from evaluated makefile code in the
3793 2002-07-03 Greg McGary <greg@mcgary.org>
3795 * dep.h (struct dep) [ignore_mtime]: New member.
3796 [changed]: convert to a bitfield.
3797 * implicit.c (pattern_search): Zero ignore_mtime.
3798 * main.c (main, handle_non_switch_argument): Likewise.
3799 * rule.c (convert_suffix_rule): Likewise.
3800 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3801 (read_makefile): Parse '|' in prerequisite list.
3802 (uniquize_deps): Consider ignore_mtime when comparing deps.
3803 * remake.c (update_file_1, check_dep): Don't force remake for
3804 dependencies that have d->ignore_mtime.
3805 * commands.c (FILE_LIST_SEPARATOR): New constant.
3806 (set_file_variables): Don't include a
3807 prerequisite in $+, $^ or $? if d->ignore_mtime.
3810 2002-06-18 Paul D. Smith <psmith@gnu.org>
3812 * make.texinfo: Updates for next revision. New date/rev/etc.
3813 Recreate all Info menus. Change license on the manual to the GNU
3814 Free Documentation License. A number of typos.
3815 (Variables Simplify): Don't use "-" before it's defined.
3816 (Automatic Prerequisites): Rewrite the target example to work
3817 properly if the compile fails. Remove incorrect comments about
3818 how "set -e" behaves.
3819 (Text Functions): Move the "word", "wordlist", "words", and
3820 "firstword" functions here, from "File Name Functions".
3821 * make-stds.texi: Update from latest GNU version.
3822 * fdl.texi: (created) Import the latest GNU version.
3824 2002-06-06 Paul D. Smith <psmith@gnu.org>
3826 * variable.c (do_variable_definition): New function: extract the
3827 part of try_variable_definition() that actually sets the value
3828 into a separate function.
3829 (try_variable_definition): Call do_variable_definition() after
3830 parsing the variable definition string.
3831 (define_variable_in_set): Make the name argument const.
3833 * variable.h (enum variable_flavor): Make public.
3834 (do_variable_definition): Create prototype.
3836 * read.c (read_all_makefiles): Create a new built-in variable,
3838 (read_makefile): Add each makefile read in to this variable value.
3840 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3842 * Makefile.DOS.template: Tweak according to changes in the
3843 distribution. Add back the dependencies of *.o files.
3845 * configh.dos.template: Synchronize with config.h.in.
3847 2002-05-09 Paul D. Smith <psmith@gnu.org>
3849 * file.c (file_timestamp_now): Use K&R function declaration.
3851 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3852 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3853 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3854 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3855 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3856 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3857 nlist.n_name is a pointer rather than an array.
3859 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3860 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3861 * configure.in: Use it instead of the old version.
3863 * main.c (main): Prefer setvbuf() to setlinebuf().
3865 2002-05-08 Paul D. Smith <psmith@gnu.org>
3867 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3868 (loadavg_LDADD): Ditto.
3870 2002-04-29 Paul D. Smith <psmith@gnu.org>
3872 * expand.c (recursively_expand_for_file): Rename
3873 recursively_expand() to recursively_expand_for_file() and provide
3874 an extra argument, struct file. If the argument is provided, set
3875 the variable scope to that of the file before expanding.
3876 * variable.h (recursively_expand): Make this a macro that invokes
3877 recursively_expand_for_file() with a NULL file pointer.
3878 * variable.c (target_environment): Call the renamed function and
3879 provide the current file context.
3880 Fixes Debian bug #144306.
3882 2002-04-28 Paul D. Smith <psmith@gnu.org>
3884 Allow $(call ...) user-defined variables to be self-referencing
3885 without throwing an error. Allows implementation of transitive
3886 closures, among other possibly useful things.
3887 Requested by: Philip Guenther <guenther@sendmail.com>
3889 * variable.h (struct variable): Add a new field: exp_count, and
3890 new macros to hold its size and maximum value.
3891 (warn_undefined): Make this a macro.
3892 * variable.c (define_variable_in_set): Initialize it.
3893 * expand.c (recursively_expand): If we detect recursive expansion
3894 of a variable, check the exp_count field. If it's greater than 0
3895 allow the recursion and decrement the count.
3896 (warn_undefined): Remove this (now a macro in variable.h).
3897 * function.c (func_call): Before we expand the user-defined
3898 function, modify its exp_count field to contain the maximum
3899 number of recursive calls we'll allow. After the call, reset it
3902 2002-04-21 Paul D. Smith <psmith@gnu.org>
3904 Modified to use latest autoconf (2.53), automake (1.6.1), and
3905 gettext (0.11.1). We're using gettext's new "external" support,
3906 to avoid including libintl source with GNU make.
3908 * README.cvs: New file. Explain how to build GNU make from CVS.
3910 * configure.in: Modify checking for the system glob library.
3911 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3912 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3913 etc. will manage it correctly). Set an automake conditional
3914 USE_LOCAL_GLOB to decide whether to compile the glob library.
3916 * getloadavg.c (main): Include make.h in the "TEST" program to
3919 * Makefile.am: Remove special rules for loadavg. Replace them
3920 with Automake capabilities for building extra programs.
3922 * signame.c: This file does nothing if the system provide
3923 strsignal(). If not, it implements strsignal(). If the system
3924 doesn't define sys_siglist, then we make our own; otherwise we use
3926 * signame.h: Removed.
3928 * main.c (main): No need to invoke signame_init(). Update copyright.
3930 * ABOUT-NLS: Removed.
3931 * gettext.c: Removed.
3932 * gettext.h: Get a simplified copy from the gettext package.
3934 * i18n/*.po: Moved to po/.
3937 * config/*: Created. Contains package configuration helper files.
3938 * config.guess, config.sub: Moved to config directory.
3940 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3941 Rework to use new-style autoconf features. Use the "external"
3942 mode for gettext. Make the build.sh config file conditional on
3943 whether build.sh.in exists, to avoid autoconf errors.
3944 * acinclude.m4: Removed almost all macros as being obsolete.
3945 Rewrote remaining macros to use AC_DEFINE.
3946 * acconfig.h: Removed.
3948 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3949 conditional to handle customs support. Remove special handling
3952 2002-04-20 Paul D. Smith <psmith@gnu.org>
3954 * function.c (func_call): Don't mark the argument variables $1,
3955 etc. as recursive. They've already been fully expanded so
3956 there's no need to do it again, and doing so strips escaped $'s.
3957 Reported by Sebastian Glita <glseba@yahoo.com>.
3959 * remake.c (notice_finished_file): Walk through double-colon
3960 entries via the prev field, not the next field!
3961 Reported by Greg McGary <greg@mcgary.org>.
3963 * main.c (main): If the user specifies -q and asks for a specific
3964 target which is a makefile, we got an assert. In that case it
3965 turns out we should continue normally instead.
3967 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3969 * i18n/he.po: Installed a new translation.
3971 2002-01-07 Paul D. Smith <psmith@gnu.org>
3973 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3975 2001-12-04 Paul D. Smith <psmith@gnu.org>
3977 * i18n/ja.po: Installed an updated translation.
3979 2001-09-06 Paul Eggert <eggert@twinsun.com>
3981 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3982 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3984 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3986 (main): Get rid of any avoidable limit on stack size.
3988 2001-09-04 Paul D. Smith <psmith@gnu.org>
3990 * i18n/da.po: Installed an updated translation.
3992 2001-08-03 Paul D. Smith <psmith@gnu.org>
3994 * i18n/fr.po: Installed an updated translation.
3995 Resolves Debian bug #106720.
3997 2001-06-13 Paul D. Smith <psmith@gnu.org>
3999 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4002 2001-06-11 Paul D. Smith <psmith@gnu.org>
4004 * i18n/ko.po: Installed a new translation.
4006 2001-05-06 Paul D. Smith <psmith@gnu.org>
4008 Modify the EINTR handling.
4010 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4011 the way in which we manage the file descriptor/signal handler race
4012 trap to be more efficient.
4014 2001-05-06 Paul Eggert <eggert@twinsun.com>
4016 Restart almost all system calls that are interrupted, instead
4017 of worrying about EINTR. The lone exception is the read() for
4020 * configure.in (HAVE_SA_RESTART): New macro.
4021 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4022 * main.c (main): Use SA_RESTART instead of the old,
4023 nonstandard SA_INTERRUPT.
4025 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4026 * main.c (bsd_signal): New function or macro,
4027 if the implementation doesn't supply it.
4028 (The bsd_signal function will be in POSIX 1003.1-200x.)
4029 (HANDLESIG): Remove.
4030 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4032 * make.h (EINTR_SET): Remove.
4033 (SA_RESTART): New macro.
4035 * arscan.c (ar_member_touch): Don't worry about EINTR.
4036 * function.c (func_shell): Likewise.
4037 * job.c (reap_children, free_child, new_job): Likewise.
4038 * main.c (main): Likewise.
4039 * remake.c (touch_file, name_mtime): Likewise.
4041 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4042 if fstat failed with errno!=EINTR, the error was ignored.
4044 * job.c (set_child_handler_action_flags): New function.
4045 (new_job): Use it to temporarily clear the SIGCHLD action flags
4046 while reading the token.
4048 2001-05-02 Paul D. Smith <psmith@gnu.org>
4050 * job.c (start_job_command): Don't add define/endef per-line flags
4051 to the top-level flags setting.
4053 2001-04-03 Paul D. Smith <psmith@gnu.org>
4055 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4056 bit on error, so check for odd return values, not non-0 return
4058 (VMS_get_member_info): Calculate the timezone differences correctly.
4059 Reported by John Fowler <jfowler@nyx.net>.
4062 2001-03-14 Paul D. Smith <psmith@gnu.org>
4064 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4065 value before invoking define_variable().
4066 Reported by John Fowler <jfowler@nyx.net>.
4068 2001-02-07 Paul D. Smith <psmith@gnu.org>
4070 * read.c (record_target_var): If we reset the variable due to a
4071 command-line variable setting overriding it, turn off the "append"
4074 2001-01-17 Paul D. Smith <psmith@gnu.org>
4076 * variable.c (lookup_variable) [VMS]: When getting values from the
4077 environment, allocate enough space for the _value_ plus escapes,
4078 not enough space for the name plus escapes :-/.
4079 Reported by John Fowler <jfowler@nyx.net>.
4081 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4082 warnings that make generates, so it doesn't look like an error.
4083 Reported by Karl Berry <karl@gnu.org>.
4086 Fix for PR/2020: Rework appended target-specific variables. I'm
4087 fairly confident this algorithm is finally correct.
4089 * expand.c (allocated_variable_append): Rewrite. Instead of
4090 expanding each appended variable then adding all the expanded
4091 strings together, we append all the unexpanded values going up
4092 through the variable set contexts, then expand the final result.
4093 This behaves just like non-target-specific appended variable
4094 values, while the old way didn't in various corner cases.
4095 (variable_append): New function: recursively append the unexpanded
4096 value of a variable, walking from the outermost variable scope to
4098 * variable.c (lookup_variable): Remove the code that looked up the
4099 variable set list if the found variable was "append". We don't
4101 (lookup_variable_in_set): Make this non-static so we can use it
4103 (try_variable_definition): Use lookup_variable_in_set() rather
4104 than faking out current_variable_set_list by hand (cleanup).
4105 * variable.h: Add a prototype for the now non-static
4106 lookup_variable_in_set().
4108 2000-11-17 Paul D. Smith <psmith@gnu.org>
4110 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4111 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4112 before throwing a fit.
4114 2000-11-17 Paul D. Smith <psmith@gnu.org>
4116 * read.c (readline): CRLF calculations had a hole, if you hit the
4117 buffer grow scenario just right. Reworked the algorithm to avoid
4118 the need for len or lastlen at all. Problem description with
4119 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4121 2000-10-24 Paul D. Smith <psmith@gnu.org>
4123 * gettext.c (SWAP): Declare this with the prototype, otherwise
4124 some systems don't work (non-32-bit? Reported for Cray T3E).
4125 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4127 2000-10-05 Paul D. Smith <psmith@gnu.org>
4129 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4130 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4132 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4134 2000-09-22 Paul D. Smith <psmith@gnu.org>
4136 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4137 parts of the real gettext.h here, and we expect to really include
4138 the real gettext.h later. If we keep this #define, it's ignored.
4140 2000-09-21 Paul D. Smith <psmith@gnu.org>
4142 * main.c (log_working_directory): Rework the text to use complete
4143 sentences, to make life simpler for the translators.
4145 2000-08-29 Paul D. Smith <psmith@gnu.org>
4147 * file.c (remove_intermediates): Print a debug message before we
4148 remove intermediate files, so the user (if she uses -d) knows
4151 2000-08-21 Paul D. Smith <psmith@gnu.org>
4153 * variable.c (try_variable_definition): Change how we handle
4154 target-specific append variable defns: instead of just setting the
4155 value, expand it as an append _but_ only within the current
4156 target's context. Otherwise we lose all but the last value if the
4157 variable is appended more than once within the current target
4158 context. Fixes PR/1831.
4160 2000-08-16 Paul D. Smith <psmith@gnu.org>
4162 * function.c (func_shell): Nul-terminate the buffer before
4163 printing an exec error message (just in case it's not!).
4164 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4166 2000-07-25 Paul D. Smith <psmith@gnu.org>
4168 * job.c (construct_command_argv_internal): Add "~" to the list of
4169 sh_chars[] which disallow optimizing out the shell call.
4171 2000-07-23 Paul Eggert <eggert@twinsun.com>
4173 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4174 supersedes --disable-nsec-timestamps.
4175 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4176 * README: Remove --disable-nsec-timestamps.
4178 * filedef.h (struct file.low_resolution_time): New member.
4179 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4180 * remake.c (update_file_1):
4181 Avoid spurious rebuilds due to low resolution time stamps,
4182 generalizing the earlier code that applied only to archive members.
4183 (f_mtime): Archive members always have low resolution time stamps.
4185 * configure.in: Remove --disable-nsec-timestamps, as this has
4186 been superseded by .LOW_RESOLUTION_TIME.
4188 2000-07-23 Paul Eggert <eggert@twinsun.com>
4190 * configure.in (enable_nsec_timestamps): Renamed from
4191 make_cv_nsec_timestamps, since enable/disable options
4192 shouldn't be cached.
4194 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4195 and Paul Eggert <eggert@twinsun.com>
4197 * file.c (file_timestamp_now):
4198 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4199 so that clock_gettime is not linked unless needed.
4201 * filedef.h (FILE_TIMESTAMP_HI_RES):
4202 Remove definition; "configure" now does this.
4204 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4205 to before high resolution file timestamp check,
4206 since that check now uses uintmax_t.
4207 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4208 high resolution file timestamps.
4209 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4210 so that we don't link in clock_gettime unnecessarily.
4212 2000-07-17 Paul D. Smith <psmith@gnu.org>
4214 * i18n/ja.po: New version of the translation file.
4216 2000-07-07 Paul D. Smith <psmith@gnu.org>
4218 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4219 the offset calculation.
4220 (name_mtime): Replace EINTR test with EINTR_SET macro.
4222 2000-07-07 Paul Eggert <eggert@twinsun.com>
4226 * remake.c (update_file_1):
4227 Avoid spurious rebuilds of archive members due to their
4228 timestamp resolution being only one second.
4229 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4230 the clock's resolution being lower than file timestamps'.
4231 When warning about future timestamps, report only the discrepancy,
4232 not the absolute value of the timestamp and the current time.
4234 * file.c (file_timestamp_now): New arg RESOLUTION.
4235 * filedef.h (file_timestamp_now): Likewise.
4236 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4238 2000-07-05 Paul D. Smith <psmith@gnu.org>
4240 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4241 to listp. Fixes PR/1793.
4243 2000-06-26 Paul Eggert <eggert@twinsun.com>
4245 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4247 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4249 * remake.c (f_mtime): Remove unused var memtime.
4251 2000-06-25 Martin Buchholz <martin@xemacs.org>
4253 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4254 Ran spell-check on make.texinfo.
4256 2000-06-23 Paul D. Smith <psmith@gnu.org>
4258 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4259 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4260 * make.h: Define these macros.
4262 * Version 3.79.1 released.
4264 * configure.in: Add a new option, --disable-nsec-timestamps, to
4265 avoid using sub-second timestamps on systems that support it. It
4266 can lead to problems, e.g. if your makefile relies on "cp -p".
4267 * README.template: Document the issue with "cp -p".
4269 * config.guess, config.sub: Updated.
