512 2010-07-01 Paul Smith <psmith@gnu.org>
514 * main.c (main): Append optional features using separate calls.
515 Not as efficient but not all compilers allow conditionals inside
516 macro calls. Fixes Savannah bug #29244.
518 2010-01-10 Paul Smith <psmith@gnu.org>

566 2009-11-12 Boris Kolpackov <boris@codesynthesis.com>
568 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
569 which allows the caller to get the index of the matching directory.
571 * make.h (vpath_search): Update prototype.
573 * remake.c (library_search): Implement linker-compatible library
574 search. Use the new VPATH_SEARCH index functionality to keep track
575 of the directory index for each match. Select the match with the
576 lowest directory index.
578 * implicit.c (pattern_search): Pass NULL for the index arguments in
579 the VPATH_SEARCH call.
581 * doc/make.texi (Directory Search for Link Libraries): Describe the
584 * NEWS: Add a note about the new behavior.
586 2009-10-25 Paul Smith <psmith@gnu.org>
588 * AUTHORS, et.al.: Update copyright years.
590 * implicit.c (stemlen_compare): Fix qsort() compare bug that
591 caused implicit rules with equal stem lengths to be sorted
594 2009-10-24 Paul Smith <psmith@gnu.org>
596 * main.c (usage): Add --eval to the usage string.
597 (switches): Add the --eval switch.
598 (main): If --eval is given, add them to the simply-expanded variable
599 -*-eval-flags-*- (necessary to allow recursion to work properly).

602 * NEWS: Describe the new --eval command line argument.
603 * doc/make.texi (Options Summary): Document --eval.

606 * read.c (eval_buffer): Ditto.
609 * variable.h (define_variable_cname): New macro for constant
611 * default.c (set_default_suffixes): Use it.

627 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
629 * read.c (do_undefine): Free the expanded variable name.
631 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
632 to normal upgrade logic from dep_hash_cmp to set_file_variables.
634 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
636 * dep.h (uniquize_deps): Remove.
638 * read.c (uniquize_deps): Merge into set_file_variables in
640 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
642 * commands.c (set_file_variables): Avoid modifying the dep
643 chain to achieve uniqueness. Fixes savannah bug 25780.
645 * implicit.c (pattern_search): Instead of re-setting all automatic
646 variables for each rule we try, just update $*.
648 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
650 * variable.h (undefine_variable_in_set): New function declaration.
651 (undefine_variable_global): New macro.
653 * variable.c (undefine_variable_in_set): New function implementation.
655 * read.c (vmodifiers): Add undefine_v modifier.

666 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
668 * implicit.c (pattern_search): Initialize file variables only
669 if we need to parse a rule that requires the second expansion.
671 2009-10-03 Paul Smith <psmith@gnu.org>
673 * make.h: Include <alloca.h> even on systems where __GNUC__ is
674 defined. Not sure why it was done the other way.
675 Requested by David Boyce <dsb@boyski.com>.
677 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
679 * dep.h (dep): Add the DONTCARE bitfield.
681 * filedef.h (file):Add the NO_DIAG bitfield.
683 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
684 not struct file (a file can be a dependency of many targets,
685 some don't care, some do).
687 * remake.c (update_goal_chain): Propagate DONTCARE from struct
688 dep to struct file before updating the goal and restore it
690 (update_file): Don't prune the dependency graph if this target
691 has failed but the diagnostics hasn't been issued.
692 (complain): Scan the file's dependency graph to find the file
693 that caused the failure.
694 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
695 whether to print diagnostics.
697 Fixes Savannah bugs #15110, #25493, #12686, and #17740.

707 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
708 much of the command line on a single pass.
710 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
712 * varible.c (create_pattern_var): Insert variables into the
713 PATTERN_VARS list in the shortest patterns first order.

730 2009-09-27 Paul Smith <psmith@gnu.org>
732 * doc/make.texi (Double-Colon): Mention that pattern rules with
733 double-colons have a different meaning. Savannah bug #27497.
735 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
737 * configh.dos.template: Remove unconditional definition of
738 SYS_SIGLIST_DECLARED.
739 Include <sys/version.h> because ports of GCC 4.3.0 and later no
740 longer include it, so macros like __DJGPP_MINOR__ are no longer
741 defined automatically.
743 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
744 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
745 instead of using the hardcoded ones.
746 (SUBDIRS): doc subdir added.
747 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
748 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
749 create html formated docs. texi2html may not be ported to DOS.
750 (make.info, make.dvi, make.ps, make.html): Make targets depend on
752 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
753 -I switch to look in ./ instead of ./doc.
754 (html): Target depend on html-recursive instead of make_1.html.
755 (make_1.html): Removed.
756 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
757 (all-recursive): Allow for more than one subdir in the build
759 (mostlyclean-recursive, clean-recursive, distclean-recursive)
760 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
761 (tags-recursive): Allow for more than one subdir in the build
763 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
764 targets. Enter into doc/ to produce the targets.
765 (all-am): $(INFO_DEPS) replaced by info.
767 2009-09-26 Paul Smith <psmith@gnu.org>
769 * read.c (record_files): Use free_ns() to free struct nameseq.
772 * rule.c (freerule): Use free_dep_chain().
774 * read.c (record_files): Free FILENAMES chain for implicit rules.
775 (eval): Static pattern targets go into the string cache.
777 * function.c (string_glob): Free NAME in the nameseq chain.
779 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
781 * implicit.c (pattern_search): Terminate early if we haven't
782 found any rules to try (performance improvement).
784 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
786 * implicit.c (pattern_search): Merge three parallel arrays,
787 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
788 of struct TRYRULE. In the old version the latter two arrays
789 had insufficient length.
791 2009-09-24 Paul Smith <psmith@gnu.org>
793 * implicit.c (pattern_search): Add back support for order-only
794 prerequisites for secondary expansion implicit rules, that were
795 accidentally dropped. If we find a "|", enable order-only mode
796 and set IGNORE_MTIME on all deps that are seen afterward.
797 (pattern_search): Fix memory leaks: for intermediate files where
798 we've already set the file variable and pattern variable sets, be
799 sure to either save or free them as appropriate.
801 2009-09-23 Paul Smith <psmith@gnu.org>
803 Rework the way secondary expansion is stored, for efficiency.
804 This changes secondary expansion so that ONLY WHEN we know we have
805 a possibility of needing secondary expansion, do we defer the
806 secondary expansion. This means more parsing the deps but we use
807 a lot less memory (due to the strcache). Also, this fixes
810 * read.c (eval): Don't parse the dep string here anymore.
811 (record_files): Take the dep argument as an unparsed string. If
812 secondary expansion is enabled AND the prereq string has a '$' in
813 it, then set NEED_2ND_EXPANSION and keep the entire string.
814 Otherwise, parse the dep string here to construct the dep list
815 with the names in the strcache.
817 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
818 duplicate the name string (others are in the strcache).
820 * implicit.c: Remove struct idep and free_idep_chain(): unused.
821 (struct patdeps): New structure to store prereq information.
822 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
823 which prerequisites need expansion, and expand only those.
825 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
826 and enter_prereqs(). split_prereqs() takes a fully-expanded string
827 and splits it into a DEP list, handling order-only prereqs.
828 (enter_prereqs): This function enters a list of DEPs into the file
829 database. If there's a stem defined, expand any pattern chars.
830 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
831 set. Use the above functions.
832 (snap_deps): Only perform second expansion on prereqs that need it,
833 as defined by the NEED_2ND_EXPANSION flag.
834 (print_prereqs): New function to print the prereqs
835 (print_file): Call print_prereqs() rather than print inline.
837 * hash.h (STRING_COMPARE): Take advantage of strcache() by
839 (STRING_N_COMPARE): Ditto.
840 (ISTRING_COMPARE): Ditto.
842 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
843 (parse_file_seq): Return void*
844 * read.c (parse_file_seq): Return void*.
845 (eval): Invoke macroized version of parse_file_seq()
846 * default.c (set_default_suffixes): Ditto.
847 * file.c (split_prereqs): Ditto.
848 * function.c (string_glob): Ditto.
849 * main.c (main): Ditto.
850 * rule.c (install_pattern_rule): Ditto.
852 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
854 2009-09-16 Paul Smith <psmith@gnu.org>
856 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
858 * dep.h: Create alloc_dep() / free_dep() macros.
860 * implicit.c (pattern_search): Take advantage of the new
861 parse_file_seq() to add the directory prefix to each prereq.
863 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
864 all. Avoid reversing chains. Support adding prefixes.
865 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
866 cached/non-cached results.
867 (eval): Remove multi_glob() & invoke new parse_file_seq().
868 * rule.c (install_pattern_rule): Ditto.
869 * main.c (main): Ditto.
870 * implicit.c (pattern_search): Ditto.
871 * function.c (string_glob): Ditto.
872 * file.c (parse_prereqs): Ditto.
873 * default.c (set_default_suffixes): Ditto.
875 * variable.c (parse_variable_definition): Don't run off the end of
876 the string if it ends in whitespace (found with valgrind).
878 * commands.c (set_file_variables): Keep space for all targets in
879 $? if -B is given (found with valgrind).
881 2009-09-15 Paul Smith <psmith@gnu.org>
883 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
884 (xcalloc): Add new function.
885 * make.h: New declarations.
887 * ar.c (ar_glob_match): New calling method for concat().
888 * main.c (main): Ditto.
889 (decode_env_switches): Ditto.
890 * read.c (eval_makefile): Ditto.
891 (tilde_expand): Ditto.
892 (parse_file_seq): Ditto.
893 * variable.c (target_environment): Ditto.
894 (sync_Path_environment): Ditto.
896 * ar.c (ar_glob_match): Use xcalloc().
897 * dir.c (file_impossible): Ditto.
898 * file.c (enter_file): Ditto.
899 * job.c (new_job): Ditto.
900 * read.c (parse_file_seq): Ditto.
901 * vmsfunctions.c (opendir): Ditto.
903 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
905 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
906 inside the loop that looks up environment for PATH.
908 2009-08-31 Eli Zaretskii <eliz@gnu.org>
910 * function.c (windows32_openpipe): Update envp after calling
911 sync_Path_environment.
913 2009-08-02 Paul Smith <psmith@gnu.org>
915 * remake.c (notice_finished_file): Ensure file->cmds is not null
916 before looping through them. Fixes Savannah bug #21824.
918 * doc/make.texi (Wildcard Examples): Clarify when objects is
919 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
920 (Include): Clarify the behavior of -include.
921 Fixes Savannah bug #18963.
923 2009-08-01 Paul Smith <psmith@gnu.org>
925 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
926 etc. come on the command line. Fixes Savannah bug #27093.
928 * expand.c (expand_argument): If the argument is large enough use
929 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
931 * variable.c (do_variable_definition): Avoid using alloca() to
932 hold values, which can be large. Fixes Savannah bug #23960.
934 * job.c (new_job): Use memmove() instead of strcpy() since both
935 pointers are in the same memory block. Fixes Savannah bug #27148.
936 Patch by Petr Machata.
938 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
940 * job.c (construct_command_argv_internal): Add "ulimit" and
941 "unset" to the sh_cmds for Unixy shells.
943 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
945 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
946 that set make_cv_sys_gnu_glob, so they are also correctly set
947 when the cache has been populated before.
949 2009-07-04 Eli Zaretskii <eliz@gnu.org>
951 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
952 exist, as realpath(3) does where it's supported.
954 2006-07-04 Eli Zaretskii <eliz@gnu.org>
956 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
957 (abspath): Support systems that define HAVE_DOS_PATHS (have
958 drive letters in their file names). Use IS_PATHSEP instead of a
959 literal '/' comparison. Fixes Savannah bug #26886.
961 2009-06-14 Paul Smith <psmith@gnu.org>
963 * remake.c (update_file_1): Remember the original file we marked
964 as updating, so we can clear that flag again. If we find a target
965 via vpath, FILE might change.
966 (check_dep): Ditto. Fixes Savannah bug #13529.
967 Patch by Reid Madsen <reid.madsen@tek.com>.
969 2009-06-13 Paul Smith <psmith@gnu.org>
971 * doc/make.texi (MAKEFILES Variable): Be explicit that files
972 included by MAKEFILES cannot give default goals.
973 * read.c (eval): If set_default is not set, pass the no-default-goal
974 value when we read included makefiles. Fixes Savannah bug #13401.
976 * ar.c (ar_name): Ensure that targets with empty parens aren't
977 considered archive member references: archive members must have a
978 non-empty "member" string. Fixes Savannah bug #18435.
980 * function.c (string_glob): Rely on multi_glob() to determine
981 whether files exist or not. Remove call to file_exists_p() which
982 is not always correct. Fixes Savannah bug #21231.
983 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
984 then only files that really exist will be returned.
985 * dep.h: Add new argument to multi_glob().
986 * rule.c (install_pattern_rule): Ditto.
987 * read.c (eval): Ditto.
988 * main.c (main): Ditto.
989 * implicit.c (pattern_search): Ditto.
990 * file.c (parse_prereqs): Ditto.
991 * default.c (set_default_suffixes): Ditto.
993 2009-06-09 Paul Smith <psmith@gnu.org>
995 * commands.c (set_file_variables): If always_make_flag is set,
996 always add the prereq to $?. Fixes Savannah bug #17825.
998 * remake.c (update_file_1): When rebuilding deps of FILE, also try
999 to rebuild the deps of all the also_make targets for that file.
1000 Fixes Savannah bug #19108.
1002 * implicit.c (pattern_search): Undo test for is_target, added by
1003 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1004 Rule Search Algorithm". Fixes Savannah bug #17752.
1006 * main.c (clean_jobserver): Clear the jobserver_fds options and
1007 set job_slots to the default when we clean up.
1008 (define_makeflags): Return the new MAKEFLAGS value.
1009 (main): Reset MAKEFLAGS in the environment when we re-exec.
1010 Fixes Savannah bug #18124.
1012 2009-06-08 Paul Smith <psmith@gnu.org>
1014 * read.c (eval): Collapse continuations post-semicolon on target-
1015 specific variables. Fixes Savannah bug #17521.
1017 2009-06-07 Paul Smith <psmith@gnu.org>
1019 * job.c (reap_children): For older systems without waitpid() (are
1020 there any of these left?) run wait(2) inside EINTRLOOP to handle
1021 EINTR errors. Fixes Savannah bug #16401.
1023 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1025 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1027 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1028 not the end, to catch second expansion $(eval ...) defining new
1029 target/prereq relationships during snap_deps.
1030 Fixes Savannah bug #24622.
1032 * read.c (record_files): The second-expansion "f->updating" hack
1033 was not completely correct: if assumed that the target with
1034 commands always had prerequisites; if one didn't then the ordering
1035 was messed up. Fixed for now to use f->updating to decide whether
1036 to preserve the last element in the deps list... but this whole
1037 area of constructing and reversing the deps list is too confusing
1038 and needs to be reworked. Fixes Savannah bug #21198.
1040 2009-06-06 Paul Smith <psmith@gnu.org>
1042 * hash.c (hash_insert): Remove useless test for NULL.
1043 Fixes Savannah bug #21823.
1045 * make.h: Move SET_STACK_SIZE determination to make.h.
1046 * main.c (main): New global variable, STACK_LIMIT, holds the
1047 original stack limit when make was started.
1048 * job.c (start_job_command): Reset the stack limit, if we changed it.
1049 Fixes Savannah bug #22010.
1051 * remake.c (check_dep): Only set the target's state to not-started
1052 if it's not already running. Found this while testing -j10 builds
1053 of glibc: various targets were being rebuilt multiple times.
1054 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1057 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1058 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1061 2009-06-04 Paul Smith <psmith@gnu.org>
1063 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1065 * maintMakefile: Modify access of config and gnulib Savannah
1066 modules to use GIT instead of CVS.
1068 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1069 Fixes Savannah bug #24655.
1071 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1072 this can happen during some invocations of $(eval ...) for example.
1073 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1075 2009-06-02 Paul Smith <psmith@gnu.org>
1077 * configure.in: Check for fileno()
1078 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1079 for the makefile file so invocations of $(shell ...) don't inherit it.
1080 Fixes Savannah bug #24277.
1082 2009-06-01 Paul Smith <psmith@gnu.org>
1084 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1085 expansion was handled incorrectly. Rework the default goal
1086 handling to save the variable only. Remove default_goal_file and
1088 * read.c (eval): Check default_goal_var, not default_goal_name.
1089 * read.c (record_target_var): Don't check default_goal_file here.
1091 2009-05-31 Paul Smith <psmith@gnu.org>
1093 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1094 it, and if the multi_glob() returns nothing (say it expanded to
1095 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1097 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1098 $(and ..) to the reference. Fixes Savannah bug #25694.
1100 * make.1: Be clear that some recipes will be executed even with -n.
1101 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1103 * doc/make.texi (Override Directive): Make more clear how
1104 overrides and appends interact.
1105 Elucidates part of Savannah bug #26207.
1107 * read.c (record_target_var): Don't reset the origin on
1108 target-specific variables; try_variable_definition() will handle
1109 this correctly. Fixes Savannah bug #26207.
1111 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1112 Fixes Savannah bug #25712.
1114 * implicit.c (pattern_search): Keep a pointer to the beginning of
1115 the filename and save that instead of the constructed pointer.
1116 Fixes Savannah bug #26593.
1117 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1119 2009-05-30 Paul Smith <psmith@gnu.org>
1121 * doc/make.texi (Multi-Line): Add a description of the new abilities
1122 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1123 "command sequence" vs. "recipe" syntax.
1124 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1125 after a define, to create variables with those flavors.
1127 2009-05-25 Paul Smith <psmith@gnu.org>
1129 Reworked the parser for variable assignments to allow multiple
1130 modifiers, and in any order. Also allows variable and
1131 prerequisites to be modifier names ('export', 'private', etc.)
1133 * NEWS: Add notes about user-visible changes.
1135 * read.c (struct vmodifiers): Remember what modifiers were seen.
1136 (parse_var_assignment): New function to parse variable assignments.
1137 (eval): Call the new function. Handle variable assignments earlier.
1139 * variable.c (parse_variable_definition): Only parse; don't create var.
1140 (assign_variable_definition): Call parse, then create the var.
1142 2009-05-24 Paul Smith <psmith@gnu.org>
1144 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1145 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.

1149 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1150 Fixes Savannah bug #25412.
1152 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1153 prototype for xmalloc.
1154 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1155 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1156 Loop over an array of extensions, instead of duplicating the same
1157 code inline. Use SearchPath followed by CreateFile, instead of
1158 the obsolete OpenFile. Fixes Savannah bug #17277.
1159 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1160 to `find_file'. Fixes Savannah bug #25662.
1162 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1164 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1165 Fixes Savannah bug #20495.
1167 2009-02-28 Ralf Wildenhues <address@hidden>
1169 * doc/make.texi (Instead of Execution): Document interaction of
1170 -t with phony targets.
1172 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1174 Introduce a new keyword "private" which applies to target-specific
1175 variables and prevents their values from being inherited.
1177 * variable.h (struct variable): Add private_var flag to each variable.
1178 Add a flag to specify which list entry switches to the parent target.

1192 * make.h: Rename savestring to xstrndup.
1193 * commands.c (chop_commands): Ditto.
1194 * function.c (func_foreach): Ditto.
1195 * read.c (eval, record_files): Ditto.

1203 * w32/subproc/build.bat (GCCBuild): Likewise.
1205 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1207 * job.c (construct_command_argv_internal): Avoid extra backslash
1208 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1211 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1213 * README.W32.template: Remove obsolete text about non-support for
1214 -jN without Unixy shell. Remove obsolete text about not supplying
1215 Visual Studio project files (we do supply them). Modify text to
1216 prefer GCC builds to MSC builds.
1218 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1220 * doc/make.texi (Empty Targets): Fix typo.

1235 `value' field is NULL.
1237 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1239 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1241 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1242 (TEXINFOS): Value changed to `doc/make.texi'.
1243 (.SUFFIXES): Use .texi instead of .texinfo.
1244 (make.info, make.dvi): Depend on doc/make.texi.
1245 (.texi.info): New target, instead of ".texinfo.info". Change -I
1246 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1247 (.texi): New target, instead of ".texinfo". Change -I switch to
1248 $(MAKEINFO) to look in doc/. Use --no-split.
1249 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1250 switch to $(MAKEINFO) to look in doc/.
1251 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1252 "*.i[0-9][0-9]" (due to --no-split above).
1253 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1254 (html, make_1.html): New targets.
1255 (.PHONY): Add "html".
1256 (.SUFFIXES): Add .html.
1258 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1260 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1261 HAVE_DECL_SYS_SIGLIST.
1263 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1264 build does not use child_execute_job.
1266 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1267 export the SHELL environment variable to the child.
1269 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1271 * config.h.W32: Include sys/types.h.
1272 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1274 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1275 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1278 2007-11-04 Paul Smith <psmith@gnu.org>
1280 * doc/make.texi: Convert references to "commands", "command
1281 lines", and "command script" to "recipe".
1283 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1286 2007-10-27 Bruno Haible <bruno@clisp.org>
1288 * remake.c (f_mtime): Print time difference values between 100 and
1289 ULONG_MAX in fixed-point notation rather than in exponention notation.
1291 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1293 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1294 a more complex value than a simple shell: if it's not a default
1295 shell now then expand it and see if is a default shell then.
1297 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1299 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1300 pathnames, with const strings.
1301 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1302 from the template (used for building from CVS, not a dist).
1304 2007-10-10 Paul Smith <psmith@gnu.org>
1306 * make.h: Add a prototype for w32_kill() (change suggested by
1307 Yongwei Wu <wuyongwei@gmail.com>).
1309 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1311 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1312 directories in Path.
1314 2007-09-12 Paul Smith <psmith@gnu.org>
1316 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1317 Provided by Diego Biurrun <diego@biurrun.de>
1318 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1319 Provided by Diego Biurrun <diego@biurrun.de>
1321 2007-09-11 Paul Smith <psmith@gnu.org>
1323 * doc/make.texi (Special Variables): Moved this into the "How to
1324 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1325 (MAKEFILE_LIST) No longer a section; this was added into the
1326 "Special Variables" section.
1327 (Rule Introduction): Reference .RECIPEPREFIX.
1328 (Simple Makefile): Ditto.
1329 (Rule Syntax): Ditto.
1330 (Command Syntax): Ditto.
1331 (Error Messages): Ditto.
1333 2007-09-10 Paul Smith <psmith@gnu.org>
1335 * commands.c (print_commands): Don't print an extra line in the
1336 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1338 * read.c (construct_include_path): Add the full string to the cache; we
1339 were chopping the last char.
1341 * NEWS: Announce the .RECIPEPREFIX special variable.
1342 * variable.c (lookup_special_var): Rename from handle_special_var().
1343 (lookup_variable): Call the new name.
1344 (set_special_var): New function: handle setting of special variables.
1345 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1346 (do_variable_definition): Call it.
1347 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1348 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1349 * main.c (main): Create the .RECIPEPREFIX special variable.
1350 * read.c (eval): Remove the cmd_prefix characters from the command
1351 scripts here, so they're not stored in the commands array at all,
1352 rather than waiting and stripping them out during command construction.
1353 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1355 2007-08-15 Paul Smith <psmith@gnu.org>
1357 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1358 file has had the section info removed, so add some to make.texi
1359 before we include it.
1361 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1363 * remake.c (check_dep): Reset the target state for intermediate
1364 files. They might have been considered before but not updated
1365 then (order-only for example) but they will be this time.
1366 Fixes Savannah bug #'s 3330 and 15919.
1368 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1370 Fix Savannah bug #20549:
1371 * function.c (func_shell): Call construct_command_argv with zero
1373 * job.c (construct_command_argv_internal): New argument FLAGS; all
1375 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1377 * job.h (construct_command_argv_internal): Update prototype.
1379 2007-07-13 Paul Smith <psmith@gnu.org>
1381 * file.c (expand_deps): Use variable_buffer as the start of the
1382 buffer, not the original pointer (in case it was reallocated).
1383 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1384 Fixes Savannah bug #20452.
1386 2007-07-04 Paul Smith <psmith@gnu.org>
1388 * (ALL FILES): Update to GPLv3.
1389 * (ALL FILES): Update copyright for 2007.

1393 2007-06-29 Thiemo Seufer <ths@mips.com>
1395 * maintMakefile: Update Translation Project location.
1397 2007-06-13 Paul Smith <psmith@gnu.org>
1399 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1400 "Expansion of a deferred"
1401 Fixes Savannah bug #20018.
1403 * expand.c (variable_expand_for_file): Preserve the value of
1404 reading_file rather than setting it to 0 at the end.
1405 Fixes Savannah bug #20033.
1407 2007-05-11 Paul Smith <psmith@gnu.org>
1409 * job.c (new_job): Add debug info to specify where make found the
1410 command script it is running to build a target.
1411 Fixes Savannah bug #18617.
1413 * default.c (default_suffixes,default_suffix_rules,default_variables):
1414 Add support for Objective C. Fixes Savannah bug #16389.
1415 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1417 * function.c (func_lastword): Initialize p.
1419 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1420 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1421 Dave Korn <dave.korn@artimi.com>
1423 2007-05-08 Paul Smith <psmith@gnu.org>
1425 Fix Savannah bug #19656:
1427 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1429 * make.h: Change all case-insensitive string compares to use
1430 strcasecmp() (from POSIX). If we don't have that but do have one
1431 of the others, define strcasecmp to be one of those instead. If
1432 we don't have any, declare a prototype for our own version.
1434 * misc.c (strcasecmp): Use this if we can't find any native
1435 case-insensitive string comparison function.
1436 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1437 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1439 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1440 strcasecmp() instead of stricmp().
1441 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1442 instead of strcmpi().
1443 * acinclude.m4: Remove the strcasecmp() check from here.
1445 2007-03-21 Paul Smith <psmith@gnu.org>
1447 * configure.in: Don't turn on case-insensitive file system support
1448 if --disable-... is given. Fixes Savannah bug #19348.
1450 2007-03-19 Paul Smith <psmith@gnu.org>
1452 * ALL: Use the strcache for all file name strings, or other
1453 strings which we will never free. The goal is to save memory by
1454 avoiding duplicate copies of strings. However, at the moment this
1455 doesn't save much memory in most situations: due to secondary
1456 expansion we actually save prerequisite lists twice (once before
1457 the secondary expansion, and then again after it's been parsed
1458 into individual file names in the dep list). We will resolve this
1459 in a future change, by doing the parsing up-front for targets
1460 where secondary expansion is not set.
1462 Moving things into the strcache also allows us to use const
1463 pointers in many more places.
1465 2007-01-03 Paul Smith <psmith@gnu.org>
1467 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1468 the function, not just the first. Fixes Savannah bug #18680.
1470 2006-11-18 Paul Smith <psmith@gnu.org>
1472 * strcache.c (strcache_add_len): Don't allocate a new buffer
1473 unless the string is not already nil-terminated. Technically this
1474 is a violation of the standard, since we may be passed an array
1475 that is not long enough to test one past. However, in make this
1476 is never true since we only use nil-terminated strings or
1477 sub-strings thereof.
1479 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1481 * main.c: New global cmd_prefix, defaults to '\t'.
1482 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1485 * dir.c: Constified.
1486 (dir_contents_file_exists_p): Check for an error return from
1487 readdir(), just in case.
1489 * commands.c: Constified.
1490 * default.c: Constified.
1491 * expand.c: Constified.
1492 * function.c: Partial constification.
1493 * variable.c: Partial constification.
1494 * vmsify.c: Constification. Hard to test this but I hope I didn't
1496 * vpath.c: Partial constification.
1497 * w32/pathstuff.c: Partial constification.
1499 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1501 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1502 backslashes and drive letters as absolute.
1504 2006-10-22 Paul Smith <psmith@gnu.org>
1506 * main.c (struct command_switch): Use const and void*.
1508 2006-10-21 Paul Smith <psmith@gnu.org>
1511 * arscan.c: Constified.
1513 2006-09-30 Paul Smith <psmith@gnu.org>
1515 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1516 point to lastword since the example was updated.
1517 Fixes Savannah bug #16304.
1518 (Secondary Expansion): Correct example description.
1519 Fixes Savannah bug #16468.
1520 (Makefile Contents): Clarify that comments cannot appear within
1521 variable references or function calls.
1522 Fixes Savannah bug #16577.
1523 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1524 Fixes Savannah bug #17701.
1525 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1526 (Prerequisite Types): Added an example of using order-only
1527 prerequisites. Fixes Savannah bug #17880.
1528 (Rule Syntax): "lise" -> "list"
1529 (Multiple Rules): ... -> @dots{}
1530 (Splitting Lines): ditto.
1532 * remake.c (update_file_1): Prereqs that don't exist should be
1533 considered changed, for the purposes of $?.
1534 Fixes Savannah bug #16051.
1536 * make.1: Remove extraneous "+".
1537 Fixes Savannah bug #16652.
1539 2006-09-06 Paul D. Smith <psmith@gnu.org>
1541 * configure.in: Include sys/types.h when checking for sys/wait.h.
1543 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1545 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1548 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1549 Normally, it is defined in config.h.
1551 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1554 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1555 sh_chars_sh for Windows platforms that emulate Unix.
1557 2006-05-07 Paul D. Smith <psmith@gnu.org>
1559 * README.OS2.template: Updates provided by Andreas Buening
1560 <andreas.buening@nexgo.de>.
1562 2006-04-30 Paul D. Smith <psmith@gnu.org>
1564 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1565 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1567 2006-04-26 Paul D. Smith <psmith@gnu.org>
1569 * README.cvs: Add a reminder to notify the GNU translation robot.
1571 * doc/make.texi: Change @direcategory (requested by Karl Berry).
1573 2006-04-20 Paul D. Smith <psmith@gnu.org>
1575 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1576 that don't have extended grep.
1577 (cvsclean): Use $(PERL) instead of perl.

1589 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1590 values from memory allocation functions: they return void* and so
1591 don't need to be cast. Also remove (char *) casts of arguments to

1623 2006-04-01 Paul D. Smith <psmith@gnu.org>
1625 Version 3.81 released.
1627 * NEWS: Updated for 3.81.
1629 * README.cvs: Mention that vpath builds are not supported out of
1630 CVS. Fixes Savannah bug #16236.
1631 Remove update of make.texi from the list of things to do; we use
1634 2006-03-26 Paul D. Smith <psmith@gnu.org>
1636 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1637 support from automake, as described in the Texinfo manual.
1639 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1641 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1642 with lastslash, since the latter points to filename, not to
1644 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1645 Declare and define sh_chars_sh[].
1647 2006-03-23 Paul D. Smith <psmith@gnu.org>
1649 * configure.in: Look for build.sh.in in $srcdir so it will be
1650 built for remote configurations as well.
1652 * Makefile.am: Make sure to clean up build.sh during distclean.
1653 Fixes Savannah bug #16166.
1655 * misc.c (log_access): Takes a const char *.
1656 * function.c (fold_newlines): Takes an unsigned int *.
1657 Both fixes for Savannah bug #16170.
1659 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1661 * implicit.c (pattern_search): Call set_file_variables only
1662 if we have prerequisites that need second expansion. Fixes
1663 Savannah bug #16140.
1665 2006-03-19 Paul D. Smith <psmith@gnu.org>
1667 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1668 memory on hosts that don't support it directly.

1671 make sure I don't forget any).
1673 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1675 (die): Cleanup code was removed from here; call the new function.

1678 Reported by Craig Fithian <craig.fithian@citigroup.com>
1680 2006-03-17 Paul D. Smith <psmith@gnu.org>
1682 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1683 allow multiple concurrent runs.
1684 Patch from Joseph Myers <joseph@codesourcery.com>
1686 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1688 * dep.h (struct dep): Add the stem field.
1689 * misc.c (alloc_dep, free_dep): New functions.
1690 (copy_dep_chain): Copy stem.
1691 (free_dep_chain): Use free_dep.
1692 * read.c (record_files): Store stem in the dependency line.
1693 * file.c (expand_deps): Use stem stored in the dependency line. Use
1694 free_dep_chain instead of free_ns_chain.
1695 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1696 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1697 * main.c (main, handle_non_switch_argument): Ditto.
1698 * remake.c (check_dep): Ditto.

1701 2006-03-14 Paul D. Smith <psmith@gnu.org>
1703 * expand.c (variable_append): Instead of appending everything then
1704 expanding the result, we expand (or not, if it's simple) each part
1706 (allocated_variable_append): Don't expand the final result.
1707 Fixes Savannah bug #15913.
1709 2006-03-09 Paul Smith <psmith@gnu.org>
1711 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1712 listed non-existent files as changed. Turns out there's a bug in
1713 the Linux kernel builds which means that this change causes
1714 everything to rebuild every time. We will re-introduce this fix
1715 in the next release, to give them time to fix their build system.
1716 Fixes Savannah bug #16002.
1717 Introduces Savannah bug #16051.
1719 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1726 locator function find_and_set_default_shell if SHELL came from the
1729 2006-02-20 Paul D. Smith <psmith@gnu.org>
1731 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1732 to be null; don't core in that case.
1734 2006-02-19 Paul D. Smith <psmith@gnu.org>
1736 * commands.c (set_file_variables): Realloc, not malloc, the static
1737 string values to avoid memory leaks.
1739 * expand.c (recursively_expand_for_file): Only set reading_file to
1740 an initialized value.
1742 * implicit.c (pattern_search): We need to make a copy of the stem
1743 if we get it from an intermediate dep, since those get freed.
1745 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1747 (enter_file) [VMS]: Ditto.
1748 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1750 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1752 * job.c (construct_command_argv_internal): Fix last change.
1754 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1755 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1756 the calls to _beginthreadex.
1758 * expand.c (recursively_expand_for_file): Initialize `save' to
1759 prevent compiler warnings.
1761 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1763 * job.c (construct_command_argv_internal): Don't create a temporary
1764 script/batch file if we are under -n. Call _setmode to switch the
1765 script file stream to text mode.
1767 2006-02-17 Paul D. Smith <psmith@gnu.org>
1769 * variable.c (merge_variable_set_lists): Don't try to merge the
1770 global_setlist. Not only is this useless, but it can lead to
1771 circularities in the linked list, if global_setlist->next in one
1772 list gets set to point to another list which also ends in
1774 Fixes Savannah bug #15757.
1776 2006-02-15 Paul D. Smith <psmith@gnu.org>
1778 Fix for Savannah bug #106.
1780 * expand.c (expanding_var): Keep track of which variable we're
1781 expanding. If no variable is being expanded, it's the same as
1783 * make.h (expanding_var): Declare it.
1784 * expand.c (recursively_expand_for_file): Set expanding_var to the
1785 current variable we're expanding, unless there's no file info in
1786 it (could happen if it comes from the command line or a default
1787 variable). Restore it before we exit.
1788 * expand.c (variable_expand_string): Use the expanding_var file
1789 info instead of the reading_file info.
1790 * function.c (check_numeric): Ditto.
1792 (func_wordlist): Ditto.
1793 (func_error): Ditto.
1794 (expand_builtin_function): Ditto.
1795 (handle_function): Ditto.
1797 2006-02-14 Paul D. Smith <psmith@gnu.org>
1799 * read.c (eval): Even if the included filenames expands to the
1800 empty string we still need to free the allocated buffer.
1802 * implicit.c (pattern_search): If we allocated a variable set for
1803 an impossible file, free it.
1804 * variable.c (free_variable_set): New function.
1805 * variable.h: Declare it.
1807 * read.c (read_all_makefiles): Makefile names are kept in the
1808 strcache, so there's never any need to alloc/free them.
1811 * main.c (main): Add "archives" to the .FEATURES variable if
1812 archive support is enabled.
1813 * doc/make.texi (Special Variables): Document it.
1815 2006-02-13 Paul D. Smith <psmith@gnu.org>
1817 * implicit.c (pattern_search): Add checking for DOS pathnames to
1818 the pattern rule target LASTSLASH manipulation.

1823 * (ALL FILES): Updated copyright and license notices.
1825 2006-02-10 Paul D. Smith <psmith@gnu.org>
1827 A new internal capability: the string cache is a read-only cache
1828 of strings, with a hash table interface for fast lookup. Nothing
1829 in the cache will ever be freed, so there's no need for reference
1830 counting, etc. This is the beginning of a full solution for
1831 Savannah bug #15182, but for now we only store makefile names here.
1833 * strcache.c: New file. Implement a read-only string cache.
1834 * make.h: Add prototypes for new functions.
1835 * main.c (initialize_global_hash_tables): Initialize the string cache.
1836 (print_data_base): Print string cache stats.
1837 * read.c (eval_makefile): Use the string cache to store makefile
1838 names. Rewrite the string allocation to be sure we free everything.
1840 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1842 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1843 directory time stamp didn't change, except on FAT filesystems.
1844 Suggested by J. David Bryan <jdbryan@acm.org>.
1846 2006-02-09 Paul D. Smith <psmith@gnu.org>
1848 * function.c (func_or): Implement a short-circuiting OR function.
1849 (func_and): Implement a short-circuiting AND function.
1850 (function_table_init): Update the table with the new functions.
1851 * doc/make.texi (Conditional Functions): Changed the "if" section
1852 to one on general conditional functions. Added documentation for
1853 $(and ...) and $(or ...) functions.
1854 * NEWS: Note new $(and ...) and $(or ...) functions.

1863 2006-02-06 Paul D. Smith <psmith@gnu.org>
1865 * vpath.c (selective_vpath_search): If the file we find has a
1866 timestamp from -o or -W, use that instead of the real time.
1867 * remake.c (f_mtime): If the mtime is a special token from -o or
1868 -W, don't overwrite it with the real mtime.
1869 Fixes Savannah bug #15341.
1871 Updates from Markus Mauhart <qwe123@chello.at>:
1873 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1874 (process_signal, process_last_err, process_exit_code): Manage
1875 invalid handle values.
1876 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1877 manage invalid handles; remove them.

1879 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1886 Fixes Savannah bug #15533.
1887 * filedef.h (struct file): Add a new LAST pointer.
1889 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1890 the comparison. For 64-bits systems the result of the subtraction
1891 might not fit into an int. Use comparison instead.
1892 Fixes Savannah bug #15534.
1894 * doc/make.texi: Update the chapter on writing commands to reflect
1895 the changes made in 3.81 for backslash/newline and SHELL handling.

1899 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1900 variable st is not used when it's not initialized.

1915 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1917 * remake.c (update_goal_chain): Set g->changed instead of
1918 incrementing it, as it is only 8-bit wide, and could overflow if
1919 many commands got started in update_file.
1921 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1923 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1941 the shell is not sh.exe.
1943 * job.c (create_batch_file): Renamed from create_batch_filename;
1944 all callers changed. Don't close the temporary file; return its
1945 file descriptor instead. New arg FD allows to return the file
1947 (construct_command_argv_internal): Use _fdopen instead of fopen to
1948 open the batch file.
1950 2006-01-04 Paul D. Smith <psmith@gnu.org>

1980 handling of backslash-newline sequences. Mention the differences
1981 on MS-DOS and MS-Windows.
1983 * NEWS: More details about building the MinGW port and a pointer
1984 to README.W32. Fix the section name that describes the new
1985 backward-incompatible processing of backslash-newline sequences.
1986 The special processing of SHELL set to "cmd" is only relevant to
1987 MS-Windows, not MS-DOS.
1989 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1991 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1992 to DWORD, to avoid compiler warnings.

2015 Patch by Mike Frysinger <vapier@gentoo.org>.
2017 2005-12-11 Paul D. Smith <psmith@gnu.org>
2019 * implicit.c (pattern_search): If 2nd expansion is not set for
2020 this implicit rule, replace the pattern with the stem directly,
2021 and don't re-expand the variable list. Along with the other

2086 2005-10-16 Paul D. Smith <psmith@gnu.org>
2088 * main.c (main): Set CURDIR to be a file variable instead of a
2089 default, so that values of CURDIR inherited from the environment
2090 won't override the make value.
2092 2005-09-26 Paul D. Smith <psmith@gnu.org>
2094 * job.c (construct_command_argv_internal): If the line is empty
2095 remember to free the temporary argv strings.
2098 2005-09-16 Paul D. Smith <psmith@gnu.org>
2100 * job.c (start_job_command): The noerror flag is a boolean (single
2101 bit); set it appropriately.
2102 Reported by Mark Eichin <eichin@metacarta.com>
2104 2005-08-29 Paul D. Smith <psmith@gnu.org>
2106 * function.c (func_error): On Windows, output from $(info ...)
2107 seems to come in the wrong order. Try to force it with fflush().
2109 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2111 * read.c (record_files): Move code that sets stem for static
2112 pattern rules out of the if (!two_colon) condition so it is
2113 also executed for two-colon rules. Fixes Savannah bug #13881.
2115 2005-08-08 Paul D. Smith <psmith@gnu.org>
2117 * make.h: Don't test that __STDC__ is non-0. Some compilers
2118 (Windows for example) set it to 0 to denote "ISO C + extensions".
2121 2005-08-07 Paul D. Smith <psmith@gnu.org>
2123 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2124 conditional (slightly different version of a fix from Eli).
2126 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2127 If make is running in parallel without -k and two jobs die in a
2128 row, but not too close to each other, then make will quit without
2129 waiting for the rest of the jobs to die.
2131 * main.c (die): Don't reset err before calling reap_children() the
2132 second time: we still want it to be in the error condition.
2133 * job.c (reap_children): Use a static variable, rather than err,
2134 to control whether or not the error message should be printed.
2136 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2138 * w32/subproc/sub_proc.c: Include signal.h.
2139 (process_pipe_io, process_file_io): Pass a pointer to a local
2140 DWORD variable to GetExitCodeProcess. If the exit code is
2141 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2143 * job.c [WINDOWS32]: Include windows.h.
2144 (main_thread) [WINDOWS32]: New global variable.
2145 (reap_children) [WINDOWS32]: Get the handle for the main thread
2146 and store it in main_thread.
2148 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2149 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2150 doing anything else. When we are done, close the main thread
2151 handle and exit with status 130.
2153 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2155 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2158 * main.c (find_and_set_default_shell): If found a DOSish shell,
2159 set sh_found and the value of default_shell, and report the
2160 findings in debug mode.
2162 * job.c (construct_command_argv_internal): Check unixy_shell, not
2163 no_default_sh_exe, to decide whether to use Unixy or DOSish
2166 * README.W32: Update with info about the MinGW build.
2168 * build_w32.bat: Support MinGW.
2170 * w32/subproc/build.bat: Likewise.
2172 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2173 printing DWORD args.
2175 * function.c (windows32_openpipe): Fix format strings for printing
2178 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2180 (start_job_command): Fix format string for printing the result of
2182 (start_job_command) [WINDOWS32]: Do not define.
2183 (exec_command): Fix format string for printing HANDLE args.
2185 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2186 to avoid compiler warnings.
2187 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2188 (Note: some of these fixes were submitted independently by J. Grant)
2190 2005-07-30 J. Grant <jg@jguk.org>
2192 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2193 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2194 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2196 2005-07-15 Paul Smith <psmith@gnu.org>
2198 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2199 we don't have a POSIX shell, then revert to the old
2200 backslash-newline behavior (where they are stripped).
2203 2005-07-08 Paul D. Smith <psmith@gnu.org>
2205 * config.h.W32.template: Reorder to match the standard config.h,
2206 for easier comparisons.
2207 From J. Grant <jg@jguk.org>
2209 * maintMakefile: Remove .dep_segment before overwriting it, in
2210 case it's not writable or noclobber is set.
2211 * expand.c (variable_expand_string): Cast result of pointer
2212 arithmetic to avoid a warning.
2213 * main.c (switches): Add full-fledged final initializer.
2215 2005-07-06 Paul D. Smith <psmith@gnu.org>
2217 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2218 * signame.c (strsignal): If we found _sys_siglist[] or
2219 __sys_siglist[] use those instead of sys_siglist[].
2220 From Albert Chin <china@thewrittenword.com>
2222 2005-07-04 Paul D. Smith <psmith@gnu.org>
2224 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2225 globfree(); set up to use the GNU versions.
2226 From Martin Zinser <zinser@zinser.no-ip.info>
2228 2005-07-03 Paul D. Smith <psmith@gnu.org>
2230 From J. Grant <jg@jguk.org>:
2232 * README.W32.template: Update the Windows and tested MSVC versions.
2233 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2234 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2235 * build_w32.bat: Ditto.
2236 * w32/subproc/build.bat: Ditto.
2238 2005-06-28 Paul D. Smith <psmith@gnu.org>
2240 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2241 declaration was checked but not present.
2243 2005-06-27 Paul D. Smith <psmith@gnu.org>
2245 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2246 to unsigned long. Fixes Savannah bug #13550.
2248 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2249 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2250 Fixes Savannah bug #13551.
2252 2005-06-26 Paul D. Smith <psmith@gnu.org>
2254 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2255 it if ANSI_STRING is not set.
2257 2005-06-25 Paul D. Smith <psmith@gnu.org>
2259 * read.c (eval): If no filenames are passed to any of the
2260 "include" variants, don't print an error.
2261 * doc/make.texi (Include): Document this.
2262 Fixes Savannah bug #1761.
2264 * job.c (construct_command_argv_internal): Sanitize handling of
2265 backslash/newline pairs according to POSIX: that is, keep the
2266 backslash-newline in the command script, but remove a following
2267 TAB character, if present. In the fast path, make sure that the
2268 behavior matches what the shell would do both inside and outside
2269 of quotes. In the slow path, quote the backslash and put a
2270 literal newline in the string.
2271 Fixes Savannah bug #1332.
2272 * doc/make.texi (Execution): Document the new behavior and give
2274 * NEWS: Make a note of the new behavior.
2276 * make.h [WINDOWS32]: #include <direct.h>.
2277 Fixes Savannah bug #13478.
2279 * remake.c (name_mtime): If the stat() of a file fails and the -L
2280 option was given and the file is a symlink, take the best mtime of
2281 the symlink we can get as the mtime of the file and don't fail.
2282 Fixes Savannah bug #13280.
2284 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2285 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2286 inside a variable reference. Make this function static as it's
2288 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2289 parsing an unexpanded line looking for semicolons.
2290 Fixes Savannah bug #1454.
2291 * misc.c (remove_comments): Move this to read.c and make it static
2292 as it's only used there. Call find_char_unquote() with new arg.
2293 * make.h: Remove prototypes for find_char_unquote() and
2294 remove_comments() since they're static now.
2296 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2297 its export flag and obtain its value. When we need to re-exec,
2298 increment the value and add it into the environment.
2299 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2300 * NEWS: Mention MAKE_RESTARTS.
2301 * main.c (always_make_set): New variable. Change the -B option to
2302 set this one instead.
2303 (main): When checking makefiles, only set always_make_flag if
2304 always_make_set is set AND the restarts flag is 0. When building
2305 normal targets, set it IFF always_make_set is set.
2306 (main): Avoid infinite recursion with -W, too: only set what-if
2307 files to NEW before we check makefiles if we've never restarted
2308 before. If we have restarted, set what-if files to NEW _after_ we
2310 Fixes Savannah bug #7566:
2312 2005-06-17 Paul D. Smith <psmith@gnu.org>
2314 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2315 in the prerequisites list.
2317 2005-06-12 Paul D. Smith <psmith@gnu.org>
2319 Fix Savannah bug # 1328.
2321 * configure.in: Check for atexit().
2322 * misc.c (close_stdout): Test stdout to see if writes to it have
2323 failed. If so, be sure to exit with a non-0 error code. Based on
2324 code found in gnulib.
2325 * make.h: Prototype.
2326 * main.c (main): Install close_stdout() with atexit().
2328 2005-06-10 Paul D. Smith <psmith@gnu.org>
2330 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2332 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2333 headers; make vmsWaitForChildren() static; extern vmsify().
2334 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2335 Don't create child_execute_job() here (it's in vmsjobs.c).
2336 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2338 2005-06-09 Paul D. Smith <psmith@gnu.org>
2340 * variable.c (push_new_variable_scope): File variables point
2341 directly to the global_setlist variable. So, inserting a new
2342 scope in front of that has no effect on those variables: they
2343 don't go through current_variable_set_list. If we're pushing a
2344 scope and the current scope is global, push it "the other way" so
2345 that the new setlist is in the global_setlist variable, and
2346 next points to a new setlist with the global variable set.
2347 (pop_variable_scope): Properly undo a push with the new
2349 Fixes Savannah bug #11913.
2351 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2353 * job.c (reap_children): Don't die of the command failed but
2354 the dontcare flag is set. Fixes Savannah bug #13216.
2356 * implicit.c (pattern_search): When creating a target from
2357 an implicit rule match, lookup pattern target and set precious
2358 flag in a newly created target. Fixes Savannah bug #13218.
2360 2005-05-13 Paul D. Smith <psmith@gnu.org>
2362 Implement "if... else if... endif" syntax.
2364 * read.c (eval): Push all checks for conditional words ("ifeq",
2365 "else", etc.) down into the conditional_line() function.
2366 (conditional_line): Rework to allow "else if..." clause. New
2367 return value -2 for lines which are not conditionals. The
2368 ignoring flag can now also be 2, which means "already parsed a
2369 true branch". If that value is seen no other branch of this
2370 conditional can be considered true. In the else parsing if there
2371 is extra text after the else, invoke conditional_line()
2372 recursively to see if it's another conditional. If not, it's an
2373 error. If so, raise the conditional value to this level instead
2374 of creating a new conditional nesting level. Special check for
2375 "else" and "endif", which aren't allowed on the "else" line.
2376 * doc/make.texi (Conditional Syntax): Document the new syntax.
2378 2005-05-09 Paul D. Smith <psmith@gnu.org>
2380 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2381 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2382 recurses to the w32 directory, even on non-Windows systems. Use
2383 the method suggested in the automake manual.
2384 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2385 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2387 2005-05-07 Paul D. Smith <psmith@gnu.org>
2389 * main.c (die): If we're dying with a fatal error (not that a
2390 command has failed), write back any leftover tokens before we go.
2392 * job.c (set_child_handler_action_flags): If there are jobs
2393 waiting for the load to go down, set an alarm to go off in 1
2394 second. This allows us to wake up from a potentially long-lasting
2395 read() and start a new job if the load has gone down. Turn it off
2397 (job_noop): Dummy signal handler function.
2398 (new_job): Invoke it with the new semantics.
2400 * docs/make.texi: Document secondary expansion. Various cleanups
2403 2005-05-03 Paul D. Smith <psmith@gnu.org>
2405 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2406 the targets which are to ultimately be made are called "goals";
2407 see the GNU make manual. Also, MAKECMDGOALS, etc.
2409 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2410 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2411 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2413 2005-05-02 Paul D. Smith <psmith@gnu.org>
2415 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2416 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2417 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2418 functions to vmsjobs.c. #include it into jobs.c.
2420 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2421 jobserver tokens. I found that this happens when an exported
2422 recursive variable contains a $(shell ...) function reference: in
2423 this situation we could "forget" to write back a token.
2425 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2426 we have. It's not reliable to depend on the number of children in
2427 our linked list so keep a separate count.
2428 (new_job): Check jobserver_tokens rather than children &&
2429 waiting_jobs. Increment jobserver_tokens when we get one.
2430 (free_child): If jobserver_tokens is 0, internal error. If it's
2431 >1, write a token back to the jobserver pipe (we don't write a
2432 token for the "free" job). Decrement jobserver_tokens.
2434 * main.c: Add variable master_job_slots.
2435 (main): Set it to hold the number of jobs requested if we're the
2436 master process, when using the jobserver.
2437 (die): Sanity checks: first test jobserver_tokens to make sure
2438 this process isn't holding any tokens we didn't write back.
2439 Second, if master_job_slots is set count the tokens left in the
2440 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2442 2005-04-24 Paul D. Smith <psmith@gnu.org>
2444 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2445 with -l# can lose jobserver tokens, because waiting jobs are not
2446 consulted properly when checking for the "free" token.
2448 * job.c (free_child): Count waiting_jobs as having tokens.
2449 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2450 handle jobs waiting for the load to drop.
2452 2005-04-23 Paul D. Smith <psmith@gnu.org>
2454 * main.c (main): Be careful to not core if a variable setting in
2455 the environment doesn't contain an '='. This is illegal but can
2456 happen in broken setups.
2457 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2459 2005-04-12 Paul D. Smith <psmith@gnu.org>
2461 The second expansion feature causes significant slowdown. Timing
2462 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2463 read the makefile before the feature, to 11+s to do the same
2464 operations after the feature. Additionally, memory usage
2465 increased drastically. To fix this I added some intelligence that
2466 avoids the overhead of the second expansion unless it's required.
2468 * dep.h: Add a new boolean field, need_2nd_expansion.
2470 * read.c (eval): When creating the struct dep for the target,
2471 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2472 (record_files): If there's a "%" in a static pattern rule, it gets
2473 converted to "$*" so set need_2nd_expansion to 1.
2475 * file.c (expand_deps): Rework to be more efficient. Only perform
2476 initialize_file_variables(), set_file_variables(), and
2477 variable_expand_for_file() if the need_2nd_expansion is set.
2479 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2480 (pattern_search): Ditto.
2481 * main.c (handle_non_switch_argument): Ditto.
2483 * read.c (read_all_makefiles): Ditto.
2484 (eval_makefile): Ditto.
2486 2005-04-07 Paul D. Smith <psmith@gnu.org>
2488 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2489 * variable.c (sync_Path_environment): Ditto.
2490 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2492 * main.c (main): Define the .FEATURES variable.
2493 * NEWS: Announce .FEATURES.
2494 * doc/make.texi (Special Variables): Document .FEATURES.
2496 * remake.c (check_dep): If a file is .PHONY, update it even if
2497 it's marked intermediate. Fixes Savannah bug #12331.
2499 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2501 * file.c (expand_deps): Factor out the second expansion and
2502 prerequisite line parsing logic from snap_deps().
2504 * file.c (snap_deps): Use expand_deps(). Expand and parse
2505 prerequisites of the .SUFFIXES special target first. Fixes
2506 Savannah bug #12320.
2508 2005-03-13 Paul D. Smith <psmith@gnu.org>
2510 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2513 2005-03-11 Paul D. Smith <psmith@gnu.org>
2515 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2516 available, not undefined (from Earnie Boyd).
2518 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2520 * implicit.c (pattern_search): Mark an intermediate target as
2521 precious if it happened to be a prerequisite of some (other)
2522 target. Fixes Savannah bug #12267.
2524 2005-03-09 Paul D. Smith <psmith@gnu.org>
2526 * read.c (eval_makefile): Add alloca(0).
2527 (eval_buffer): Ditto.
2529 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2531 * main.c (main): Use o_file instead of o_default when defining
2532 the .DEFAULT_TARGET special variable.
2533 * read.c (eval): Use define_variable_global() instead of
2534 define_variable() when setting new value for the .DEFAULT_TARGET
2535 special variable. Fixes Savannah bug #12266.
2537 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2539 * imlicit.c (pattern_search): Mark files for which an implicit
2540 rule has been found as targets. Fixes Savannah bug #12202.
2542 2005-03-04 Paul D. Smith <psmith@gnu.org>
2545 * doc/make.texi (Automatic Variables): Document $|.
2547 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2549 * read.c (record_files): Instead of substituting % with
2550 actual stem value in dependency list replace it with $*.
2551 This fixes stem triple expansion bug.
2553 * implicit.c (pattern_search): Copy stem to a separate
2554 buffer and make it a properly terminated string. Assign
2555 this buffer instead of STEM (which is not terminated) to
2556 f->stem. Instead of substituting % with actual stem value
2557 in dependency list replace it with $*. This fixes stem
2558 triple expansion bug.
2560 2005-03-01 Paul D. Smith <psmith@gnu.org>
2562 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2563 on Windows, as it takes a handle not a pid. Just exit.
2564 Fix from patch #3679, provided by Alessandro Vesely.
2566 * configure.in: Update check for sys_siglist[] from autoconf manual.
2567 * signame.c (strsignal): Update to use the new autoconf macro.
2569 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2571 * read.c (record_files): Add a check for the list of prerequisites
2572 of a static pattern rule being empty. Fixes Savannah bug #12180.
2574 2005-02-28 Paul D. Smith <psmith@gnu.org>
2576 * doc/make.texi (Text Functions): Update docs to allow the end
2577 ordinal for $(wordlist ...) to be 0.
2578 * function.c (func_wordlist): Fail if the start ordinal for
2579 $(wordlist ...) is <1. Matches documentation.
2580 Resolves Savannah support request #103195.
2582 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2583 previously we were stopping when !-q, exactly the opposite. This
2584 has been wrong since version 1.34, in 1994!
2585 (update_file): If we got an error don't break out to run more
2586 double-colon rules: just return immediately.
2587 Fixes Savannah bug #7144.
2589 2005-02-27 Paul D. Smith <psmith@gnu.org>
2591 * misc.c (end_of_token): Make argument const.
2592 * make.h: Update prototype.
2594 * function.c (abspath, func_realpath, func_abspath): Use
2595 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2596 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2597 * read.c (record_files): Ditto.
2598 * variable.c (do_variable_definition): Ditto.
2600 * function.c (func_error): Create a new function $(info ...) that
2601 simply prints the message to stdout with no extras.
2602 (function_table_init): Add new function to the table.
2603 * NEWS: Add $(info ...) reference.
2604 * doc/make.texi (Make Control Functions): Document it.
2606 New feature: if the system supports symbolic links, and the user
2607 provides the -L/--check-symlink-time flag, then use the latest
2608 mtime between the symlink(s) and the target file.
2610 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2611 readlink(). If both are available, define MAKE_SYMLINKS.
2612 * main.c: New variable: check_symlink_flag.
2613 (usage): Add a line for -L/--check-symlink-times to the help string.
2614 (switches): Add -L/--check-symlink-times command line argument.
2615 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2616 print a warning and disable it again.
2617 * make.h: Declare check_symlink_flag.
2618 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2619 if the file is a symlink then check each link in the chain and
2620 choose the NEWEST mtime we find as the mtime for the file. The
2621 newest mtime might be the file itself!
2622 * NEWS: Add information about this new feature.
2623 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2625 Avoid core dumps described in Savannah bug # 12124:
2627 * file.c: New variable snapped_deps remember whether we've run
2629 (snap_deps): Set it.
2630 * filedef.h: Extern it.
2631 * read.c (record_files): Check snapped_deps; if it's set then
2632 we're trying to eval a new target/prerequisite relationship from
2633 within a command script, which we don't support. Fatal.
2635 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2637 Implementation of the .DEFAULT_TARGET special variable.
2639 * read.c (eval): If necessary, update default_target_name when
2641 * read.c (record_files): Update default_target_file if
2642 default_target_name has changed.
2643 * main.c (default_target_name): Define.
2644 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2645 default_target_name is set use default_target_file as a root
2647 * filedef.h (default_target_name): Declare.
2648 * dep.h (free_dep_chain):
2649 * misc.c (free_dep_chain): Change to operate on struct nameseq
2650 and change name to free_ns_chain.
2651 * file.c (snap_deps): Update to use free_ns_chain.
2653 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2655 Implementation of the second expansion in explicit rules,
2656 static pattern rules and implicit rules.
2658 * read.c (eval): Refrain from chopping up rule's dependencies.
2659 Store them in a struct dep as a single dependency line. Remove
2660 the code that implements SySV-style automatic variables.
2662 * read.c (record_files): Adjust the code that handles static
2663 pattern rules to expand all percents instead of only the first
2664 one. Reverse the order in which dependencies are stored so that
2665 when the second expansion reverses them again they appear in
2666 the makefile order (with some exceptions, see comments in
2667 the code). Remove the code that implements SySV-style automatic
2670 * file.c (snap_deps): Implement the second expansion and chopping
2671 of dependency lines for explicit rules.
2673 * implicit.c (struct idep): Define an auxiliary data type to hold
2674 implicit rule's dependencies after stem substitution and
2677 * implicit.c (free_idep_chain): Implement.
2679 * implicit.c (get_next_word): Implement helper function for
2680 parsing implicit rule's dependency lines into words taking
2681 into account variable expansion requests. Used in the stem
2684 * implicit.c (pattern_search): Implement the second expansion
2685 for implicit rules. Also fixes bug #12091.
2687 * commands.h (set_file_variables): Declare.
2688 * commands.c (set_file_variables): Remove static specifier.
2690 * dep.h (free_dep_chain): Declare.
2691 * misc.c (free_dep_chain): Implement.
2693 * variable.h (variable_expand_for_file): Declare.
2694 * expand.c (variable_expand_for_file): Remove static specifier.
2696 * make.h (strip_whitespace): Declare.
2697 * function.c (strip_whitespace): Remove static specifier.
2699 2005-02-26 Paul D. Smith <psmith@gnu.org>
2701 * main.c (main): Check for ferror() when reading makefiles from stdin.
2702 Apparently some shells in Windows don't close pipes properly and
2705 2005-02-24 Jonathan Grant <jg@jguk.org>
2707 * configure.in: Add MinGW configuration options, and extra w32 code
2709 * Makefile.am: Add MinGW configuration options, and extra w32 code
2711 * main.c: Determine correct program string (after last \ without .exe).
2712 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2714 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2715 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2716 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2717 environment support.
2719 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2721 * function.c (func_shell): When initializing error_prefix, check
2722 that reading file name is not null. This fixes long-standing
2723 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2725 2005-02-09 Paul D. Smith <psmith@gnu.org>
2727 * maintMakefile: Update the CVS download URL to simplify them.
2728 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2729 downloading the .texi files from Savannah now.
2731 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2733 * main.c (handle_non_switch_argument): Only add variables to
2734 command_variables if they're not already there: duplicate settings
2735 waste space and can be confusing to read.
2737 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2738 this header is never included by non-WINDOWS32 code, and it
2739 requires <config.h> to define which isn't always included first.
2741 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2742 testing MINGW32 versions.
2744 * main.c (log_working_directory): flush stdout to be sure the WD
2745 change is printed before any stderr messages show up.
2747 2005-02-01 Paul D. Smith <psmith@gnu.org>
2749 * maintMakefile (po_repo): Update the GNU translation site URL.
2751 2004-12-01 Paul D. Smith <psmith@gnu.org>
2753 * main.c (main): Change char* env_shell to struct variable shell_var.
2754 * variable.c (target_environment): Use new shell_var.
2756 2004-11-30 Paul D. Smith <psmith@gnu.org>
2758 * configure.in: The old way we avoided creating build.sh from
2759 build.sh.in before build.sh.in exists doesn't work anymore; we
2760 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2761 the help!). This also keeps automake from complaining.
2762 * Makefile.am (README): Add a dummy target so automake won't
2763 complain that this file doesn't exist when we checkout from CVS.
2764 * maintMakefile (.dep_segment): Rewrite this rule since newer
2765 versions of automake don't provide DEP_FILES.
2767 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2769 Implementation of `realpath' and `abspath' built-in functions.
2771 * configure.in: Check for realpath.
2772 * function.c (abspath): Return an absolute file name that does
2773 not contain any `.' or `..' components, nor repeated `/'.
2774 * function.c (func_abspath): For each name call abspath.
2775 * function.c (func_realpath): For each name call realpath
2776 from libc or delegate to abspath if realpath is not available.
2777 * doc/make.texi (Functions for File Names): Document new functions.
2778 * doc/make.texi (Quick Reference): Ditto.
2780 2004-11-28 Paul D. Smith <psmith@gnu.org>
2782 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2783 arguments. Fixes bug #10252.
2785 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2787 * main.c (main): Set SHELL to v_noexport by default. Remember the
2788 original environment setting of SHELL in the env_shell variable.
2789 * main.h: Export new env_shell variable.
2790 * variable.c (target_environment): If we find a v_noexport
2791 variable for SHELL, add a SHELL variable with the env_shell value.
2792 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2793 * doc/make.texi (Variables/Recursion): Ditto.
2795 2004-11-28 Paul D. Smith <psmith@gnu.org>
2797 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2798 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2799 Patch by Alessandro Vesely.
2801 2004-11-12 Paul D. Smith <psmith@gnu.org>
2803 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2804 the command line if it's inside a string.
2805 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2807 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2809 * function.c (func_lastword): New function: return last word
2810 from the list of words.
2811 * doc/make.texi: Document $(lastword ). Fix broken links in
2812 Quick Reference section.
2814 2004-10-06 Paul D. Smith <psmith@gnu.org>
2816 Apply patch from Alessandro Vesely, provided with bug # 9748.
2817 Fix use of tmpnam() to work with Borland C.
2819 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2820 construction of a temporary filename, and call new function
2821 create_batch_filename().
2822 (create_batch_filename) [WINDOWS32]: New function to create a
2825 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2827 * read.c (record_target_var): Expand simple pattern-specific
2829 * variable.c (initialize_file_variables): Do not expand simple
2830 pattern-specific variable.
2832 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2834 * remake.c (update_file_1): When rebuilding makefiles inherit
2835 dontcare flag from a target that triggered update.
2837 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2839 * variable.c (initialize_file_variables): Mark pattern-specific
2840 variable as a per-target and copy export status.
2842 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2844 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2846 * implicit.c (pattern_search): When considering an implicit rule's
2847 prerequisite check that it is actually a target rather then
2848 just an entry in the file hashtable.
2850 2004-09-21 Paul D. Smith <psmith@gnu.org>
2852 * read.c (readstring): Fix some logic errors in backslash handling.
2853 (eval): Remove some unnecessary processing in buffer handling.
2854 (record_target_var): Assert that parse_variable_definition() succeeded.
2855 Reported by: Markus Mauhart <qwe123@chello.at>.
2857 * misc.c: Removed the sindex() function. All instances of this
2858 function were trivially replaceable by the standard strstr()
2859 function, and that function will always have better (or certainly
2860 no worse) performance than the very simple-minded algorithm
2861 sindex() used. This can matter with complex makefiles.
2862 * make.h: Remove the prototype for sindex().
2863 * function.c (subst_expand): Convert sindex() call to strstr().
2864 This means we no longer need to track the TLEN value so remove that.
2865 (func_findstring): Convert sindex() to strstr().
2866 * commands.c (chop_commands): Convert sindex() calls to strstr().
2867 Suggested by: Markus Mauhart <qwe123@chello.at>.
2869 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2870 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2871 If SHELL is set to CMD.EXE then assume it's batch-mode and
2872 non-unixy. I wrote the code differently from the patch, though,
2873 to make it safer. This also resolves bug #9174.
2875 2004-09-20 Paul D. Smith <psmith@gnu.org>
2877 * expand.c (variable_expand_string): Modify to invoke
2878 patsubst_expand() instead of subst_expand(); the latter didn't
2879 handle suffix patterns correctly.
2880 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2881 was used only from variable_expand_string() and is no longer used
2883 (func_subst): Ditto, on call to subst_expand().
2884 (patsubst_expand): Require the percent pointers to point to the
2885 character after the %, not to the % itself.
2886 * read.c (record_files): New call criteria for patsubst_expand().
2887 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2888 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2890 2004-09-19 Paul D. Smith <psmith@gnu.org>
2892 * function.c (subst_expand): Fix a check in by_word: look for a
2893 previous blank if we're beyond the beginning of the string, not
2894 the beginning of the word.
2895 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2897 2004-05-16 Paul D. Smith <psmith@gnu.org>
2899 * remake.c (update_goal_chain): Change the argument specifying
2900 whether we're rebuilding makefiles to be a global variable,
2901 REBUILDING_MAKEFILES.
2902 (complain): Extract the code that complains about no rules to make
2903 a target into a separate function.
2904 (update_file_1): If we tried to rebuild a file during the makefile
2905 rebuild phase and it was dontcare, then no message was printed.
2906 If we then try to build the same file during the normal build,
2907 print a message this time.
2908 (remake_file): Don't complain about un-remake-able files when
2909 we're rebuilding makefiles.
2911 2004-05-11 Paul D. Smith <psmith@gnu.org>
2913 * job.c (construct_command_argv_internal): OS/2 patches from
2914 Andreas Buening <andreas.buening@nexgo.de>.
2916 2004-05-10 Paul D. Smith <psmith@gnu.org>
2918 * remake.c (update_file): Don't walk the double-colon chain unless
2919 this is a double-colon rule. Fix suggested by Boris Kolpackov
2920 <boris@kolpackov.net>.
2922 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2923 * readme.vms: New section describing OpenVMS support and issues.
2924 * default.c (default_variables): Add support for IA64.
2925 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2926 without some privilege aborts make with the error
2927 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2928 pressing Ctrl+Y and the input device is no terminal. The change
2929 catches this error and just continues.
2931 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2933 2004-04-25 Paul D. Smith <psmith@gnu.org>
2935 * commands.c (set_file_variables): Set $< properly in the face of
2936 order-only prerequisites.
2937 Patch from Boris Kolpackov <boris@kolpackov.net>
2939 2004-04-21 Bob Byrnes <byrnes@curl.com>
2941 * main.c (main): Notice failures to remake makefiles.
2943 2004-03-28 Paul D. Smith <psmith@gnu.org>
2945 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2947 * job.c: No default shell for RISC OS.
2948 (load_too_high): Hard-code the return to 1.
2949 (construct_command_argv_internal): No sh_chars or sh_cmds.
2950 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2952 2004-03-20 Paul D. Smith <psmith@gnu.org>
2954 * variable.c (do_variable_definition): Don't append from the
2955 global set if a previous non-appending target-specific variable
2956 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2959 * expand.c (reference_variable): Don't give up on variables with
2960 no value that have the target-specific append flag set: they might
2961 have a value after all. Reported by Oliver Schmidt
2962 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2963 <nikulin@dx1cmd.inp.nsk.su>.
2965 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2966 refer to absolute pathnames in directories that don't exist: some
2967 portion of the makefile could create those directories before we
2968 match the pattern. Fixes bugs #775 and #108.
2970 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2972 * main.c (main): Free makefile_mtimes if we have any.
2973 * README.W32.template: Update documentation for the current status
2974 of the MS-Windows port.
2975 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2976 environment variable is sometimes already defined which causes the
2978 * main.c (debug_signal_handler): Only define this function if
2979 SIGUSR1 is available.
2981 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2983 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2984 * README.OS2.template: Documentation updates.
2985 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2986 link line for safety.
2987 * maintMakefile (build.sh.in): Remove an extraneous ")".
2988 * job.c (child_execute_job): Close saved FDs.
2989 * job.c (exec_command) [OS/2]: exec_command(): If the command
2990 can't be exec'ed and if the shell is not Unix-sh, then try again
2991 with argv = { "cmd", "/c", ... }. Normally, this code is never
2992 reached for the cmd shell unless the command really doesn't exist.
2993 (construct_command_argv_internal) [OS/2]: The code for cmd
2994 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2995 The CMD builtin commands are case insensitive so use strcasecmp().
2997 2004-03-19 Paul D. Smith <psmith@gnu.org>
2999 * read.c (do_define): Re-order line counter increment so the count
3000 is accurate (we were losing one line per define). Reported by
3001 Dave Yost <Dave@Yost.com>.
3003 2004-03-06 Paul D. Smith <psmith@gnu.org>
3005 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3007 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3008 * misc.c (message,error,fatal): Ditto.
3009 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3010 * config.h.W32.template: Ditto.
3011 * config.h-vms.template: Ditto.
3012 * config.ami.template: Ditto.
3014 2004-03-04 Paul D. Smith <psmith@gnu.org>
3016 * README.template: Add a note about broken /bin/sh on SunOS
3017 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3019 * misc.c (message, error, fatal): Don't use "..." if we're using
3020 varargs. ansi2knr should handle this but it doesn't work: it
3021 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3022 done. On many systems (SunOS for example) va_dcl is a #define.
3023 So, force the use of the non-"..." version on pre-ANSI compilers.
3025 * maintMakefile (sign-dist): Create some rules to help automate
3026 the new GNU ftp upload method.
3028 2004-02-24 Paul D. Smith <psmith@gnu.org>
3030 * config.h.W32.template: Add HAVE_STDARG_H
3031 * config.h-vms.template: Ditto.
3032 * config.ami.template: Ditto.
3034 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3036 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3037 * build_w32.bat: Remove extra "+".
3039 2004-02-23 Paul D. Smith <psmith@gnu.org>
3041 * make.h: Create an UNUSED macro to mark unused parameters.
3042 * (many): Clean up warnings by applying UNUSED, fixing
3043 signed/unsigned incompatibilities, etc.
3045 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3047 * filedef.h: Name the command_state enumeration.
3048 * file.c (set_command_state): Use the enumeration in the function
3051 * configure.in: Explicitly set SET_MAKE to empty, to disable
3052 MAKE=make even when no make already exists. Fix bug #3823.
3054 2004-02-22 Paul D. Smith <psmith@gnu.org>
3056 * maintMakefile: Perl script to clean up all non-CVS files. Use
3057 it on all the subdirectories for the cvs-clean target.
3059 * main.c (decode_switches): Require non-empty strings for all our
3060 string command-line options. Fixes Debian bug # 164165.
3062 * configure.in: Check for stdarg.h and varargs.h.
3063 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3064 for printing messages.
3065 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3070 A number of patches for OS/2 support from Andreas Buening
3071 <andreas.buening@nexgo.de>:
3073 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3074 disable the SIGCHLD handler.
3075 (reap_children) [OS/2]: Remove special handling of job_rfd.
3076 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3077 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3078 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3079 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3080 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3083 2004-02-21 Paul D. Smith <psmith@gnu.org>
3085 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3086 <mail@kristov.de> reports that if process_begin() fails we don't
3087 handle the error condition correctly in all cases.
3088 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3089 to have a newline on the message.
3091 * job.c (construct_command_argv_internal): Add "test" to UNIX
3092 sh_cmds[]. Fixes Savannah bug # 7606.
3094 2004-02-04 Paul D. Smith <psmith@gnu.org>
3096 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3097 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3098 Hartmut Becker <Hartmut.Becker@hp.com>.
3100 2004-01-21 Paul D. Smith <psmith@gnu.org>
3102 * job.c (load_too_high): Implement an algorithm to control the
3103 "thundering herd" problem when using -l to control job creation
3104 via the load average. The system only recomputes the load once a
3105 second but we can start many jobs in a second. To solve this we
3106 keep track of the number of jobs started in the last second and
3107 apply a weight to try to guess what a correct load would be.
3108 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3109 Also fixes bug #4693.
3110 (reap_children): Decrease the job count for this second.
3111 (start_job_command): Increase the job count for this second.
3113 * read.c (conditional_line): Expand the text after ifn?def before
3114 checking to see if it's a single word. Fixes bug #7257.
3116 2004-01-09 Paul D. Smith <psmith@gnu.org>
3118 * file.c (print_file): Recurse to print all targets in
3119 double-colon rules. Fixes bug #4518, reported (with patch) by
3120 Andrew Chatham <chatham@google.com>.
3122 2004-01-07 Paul D. Smith <psmith@gnu.org>
3124 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3125 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3126 AC_FUNC_SETVBUF_REVERSED.
3128 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3129 (MAKE Variable): Fix Savannah bug #4898.
3131 * job.c (construct_command_argv_internal): Add "!" to the list of
3132 shell escape chars. POSIX sh allows it to appear before a
3133 command, to negate the exit code. Fixes bug #6404.
3135 * implicit.c (pattern_search): When matching an implicit rule,
3136 remember which dependencies have the ignore_mtime flag set.
3137 Original fix provided in Savannah patch #2349, by Benoit
3138 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3140 2003-11-22 Paul D. Smith <psmith@gnu.org>
3142 * README.W32.template (Outputs): Clarification on -j with
3143 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3146 2003-11-02 Paul D. Smith <psmith@gnu.org>
3148 * function.c (func_if): Strip all the trailing whitespace from the
3149 condition, then don't expand it. Fixed bug # 5798.
3151 * expand.c (recursively_expand_for_file): If we're expanding a
3152 variable with no file context, then use the variable's context.
3155 2003-10-21 Paul D. Smith <psmith@gnu.org>
3157 * main.c (log_working_directory): Add newlines to printf()s.
3159 * README.cvs: Add a note to ignore warnings during autoreconf.
3161 * maintMakefile (po_repo): Set a new URL for PO file updates.
3162 (get-config/config.guess get-config/config.sub): Get these files
3163 from the Savannah config project instead of ftp.gnu.org.
3165 2003-10-05 Paul Eggert <eggert@twinsun.com>
3167 * main.c (main): Avoid potential subscript error if environ has
3170 2003-08-22 Paul D. Smith <psmith@gnu.org>
3172 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3173 systems which don't yet implement the C89 standard :-/.
3175 2003-07-18 Paul D. Smith <psmith@gnu.org>
3177 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3178 [WINDOWS32]: Initialize hash.
3180 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3182 * dir.c (read_dirstream): Provide a workaround for broken versions of
3183 the MinGW dirent structure.
3185 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3187 * w32/include/dirent.h: Add __MINGW32__ filter.
3189 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3191 * make.h: Add global declaration of *make_host.
3192 * main.c (print_usage): Remove local declaration of *make_host.
3193 (print_version): Display "This program built for ..." after Copyright
3196 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3198 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3199 execution of "makeinfo --html make.texi".
3201 2003-04-30 Paul D. Smith <psmith@gnu.org>
3203 * build.template: Make some changes to maybe allow this script to
3204 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3206 * README.OS2.template: New file for OS/2 support. Original
3207 contributed by Andreas Buening.
3208 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3211 2003-04-19 Paul D. Smith <psmith@gnu.org>
3213 Fix bug #1405: allow a target to match multiple pattern-specific
3216 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3217 variable.c, where they've always belonged.
3218 * rule.h: Move the prototypes and struct pattern_var as well.
3219 * variable.c (initialize_file_variables): Invoke
3220 lookup_pattern_var() in a loop, until no more matches are found.
3221 If a match is found, create a new variable set for the target's
3222 pattern variables. Then merge the contents of each matching
3223 pattern variable set into the target's pattern variable set.
3224 (lookup_pattern_var): Change this function to be usable
3225 in a loop. It takes a starting position: if NULL, start at the
3226 beginning; if non-NULL, start with the pattern variable after that
3227 position, and return the next matching pattern.
3228 (create_pattern_var): Create a unique instance of
3229 pattern-specific variables for every definition in the makefile.
3230 Don't combine the same pattern together. This allows us to
3231 process the variable handling properly even when the same pattern
3232 is used multiple times.
3233 (parse_variable_definition): New function: break out the parsing
3234 of a variable definition line from try_variable_definition.
3235 (try_variable_definition): Call parse_variable_definition to
3237 (print_variable_data_base): Print out pattern-specific variables.
3238 * variable.h (struct variable): Remember when a variable is
3239 conditional. Also remember its flavor.
3240 (struct pattern_var): Instead of keeping a variable set, we just
3241 keep a single variable for each pattern.
3242 * read.c (record_target_var): Each pattern variable contains only a
3243 single variable, not a set, so create it properly.
3244 * doc/make.texi (Pattern-specific): Document the new behavior.
3246 2003-04-17 Paul D. Smith <psmith@gnu.org>
3248 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3249 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3250 file/directory naming rules for VMS so I can't tell whether this
3253 2003-04-09 Paul D. Smith <psmith@gnu.org>
3255 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3256 DOS-style pathnames: backslash separators and drive specifiers.
3258 2003-03-28 Paul D. Smith <psmith@gnu.org>
3260 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3261 the intermediate flag on all targets. Fixes bug #2515.
3263 2003-03-24 Paul D. Smith <psmith@gnu.org>
3265 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3266 Upgrade to autoconf 2.57 and automake 1.7.3.
3268 * job.c: More OS/2 changes from Andreas Buening.
3270 * file.c (print_file): Fix variable initialization.
3273 * remake.c (notice_finished_file):
3275 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3276 some calls (like readdir()) return NULL in valid situations
3277 without resetting errno. Fixes bug #2846.
3279 2003-02-25 Paul D. Smith <psmith@gnu.org>
3281 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3283 * job.c (_is_unixy_shell) [OS/2]: New function.
3284 Set default shell to /bin/sh.
3285 (reap_children): Close the job_rfd pipe here since we don't use a
3287 (set_child_handler_action_flags): define this to empty on OS/2.
3288 (start_job_command): Close the jobserver pipe and use
3289 child_execute_job() instead of fork/exec.
3290 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3291 rather than exec'ing, then reconfigure stdin/stdout.
3292 (exec_command): Rewrite to use spawn instead of exec. Return the
3295 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3296 in DOS. Handle the TEMP environment variable as in DOS. Don't
3297 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3298 use -j in DOS mode. Use child_execute_job() instead of
3301 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3304 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3305 prototypes that return values.
3307 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3309 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3310 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3312 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3315 2003-02-24 Paul D. Smith <psmith@gnu.org>
3317 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3318 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3319 (child_execute_job) [VMS]: Handle error status properly.
3320 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3322 * function.c (func_shell): Use EINTRLOOP() while reading from the
3323 subshell pipe (Fixes bug #2502).
3324 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3326 * main.c (main): Ditto.
3328 2003-01-30 Paul D. Smith <psmith@gnu.org>
3330 * read.c (eval): eval() was not fully reentrant, because the
3331 collapsed buffer was static. Change it to be an automatic
3332 variable so that eval() can be invoked recursively.
3334 (eval): Apply patch # 1022: fix memory reference error on long
3335 target-specific variable lines.
3336 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3338 * function.c (check_numeric): Combine the is_numeric() function
3339 into this function, since it's only called from one place.
3340 Constify this function. Have it print the incorrect string in the
3341 error message. Fixes bug #2407.
3342 (strip_whitespace): Constify.
3343 (func_if): Constify.
3344 * expand.c (expand_argument): Constify.
3346 2003-01-29 Paul D. Smith <psmith@gnu.org>
3348 Fix bug # 2169, also reported by other people on various systems.
3350 * make.h: Some systems, such as Solaris and PTX, do not fully
3351 implement POSIX-compliant SA_RESTART functionality; important
3352 system calls like stat() and readdir() can still fail with EINTR
3353 even if SA_RESTART has been set on the signal handler. So,
3354 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3355 EINTR for system calls which return -1 or 0 (NULL), respectively,
3357 Also, remove the old atomic_stat()/atomic_readdir() and
3358 HAVE_BROKEN_RESTART handling.
3360 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3362 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3363 * remake.c (touch_file): Ditto.
3365 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3366 * read.c (construct_include_path): Ditto.
3367 * remake.c (name_mtime): Ditto.
3368 * vpath.c (selective_vpath_search): Ditto.
3369 * dir.c (find_directory): Ditto.
3370 (local_stat): Ditto.
3371 (find_directory): Use ENULLLOOP() to wrap opendir().
3372 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3374 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3375 atomic_readdir() handling.
3377 2003-01-22 Paul D. Smith <psmith@gnu.org>
3379 * function.c (func_call): Fix Bug #1744. If we're inside a
3380 recursive invocation of $(call ...), mask any of the outer
3381 invocation's arguments that aren't used by this one, so that this
3382 invocation doesn't "inherit" them accidentally.
3384 2002-12-05 Paul D. Smith <psmith@gnu.org>
3386 * function.c (subst_expand): Valery Khamenia reported a
3387 pathological performance hit when doing substitutions on very
3388 large values with lots of words: turns out we were invoking
3389 strlen() a ridiculous number of times. Instead of having each
3390 call to sindex() call strlen() again, keep track of how much of
3391 the text we've seen and pass the length to sindex().
3393 2002-11-19 Paul D. Smith <psmith@gnu.org>
3395 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3398 2002-11-16 Paul D. Smith <psmith@gnu.org>
3400 * NMakefile.template (OBJS): Add hash.c object file.
3401 * SMakefile.template (srcs): Ditto.
3402 * Makefile.ami (objs): Ditto.
3403 * build_w32.bat: Ditto.
3405 * Makefile.DOS.template: Remove extra dependencies.
3407 2002-10-25 Paul D. Smith <psmith@gnu.org>
3409 * expand.c (install_variable_buffer): New function. Install a new
3410 variable_buffer context and return the previous one.
3411 (restore_variable_buffer): New function. Free the current
3412 variable_buffer context and put a previously saved one back.
3413 * variable.h: Prototypes for {install,restore}_variable_buffer.
3414 * function.c (func_eval): Push a new variable_buffer context
3415 before we eval, then restore the old one when we're done.
3418 * read.c (install_conditionals): New function. Install a new
3419 conditional context and return the previous one.
3420 (restore_conditionals): New function. Free the current
3421 conditional context and put a previously saved one back.
3422 (eval): Use the {install,restore}_conditionals for "include"
3424 (eval_buffer): Use {install,restore}_conditionals to preserve the
3425 present conditional state before we evaluate the buffer.
3428 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3430 (Recursion): Add a variable index entry for CURDIR.
3432 * README.cvs: Update to appropriate versions.
3433 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3434 don't need to copy loadavg.c: automake is smart enough to create
3435 it for me. Still have a bug in automake related to ansi2knr tho.
3437 2002-10-14 Paul D. Smith <psmith@gnu.org>
3439 * remake.c (notice_finished_file): Only touch targets if they have
3440 at least one command (as per POSIX). Resolve Bug #1418.
3442 * *.c: Convert to using ANSI C-style function definitions.
3443 * Makefile.am: Enable the ansi2knr feature of automake.
3444 * configure.in: ditto.
3446 2002-10-13 Paul D. Smith <psmith@gnu.org>
3448 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3449 for automatic variable values like $^, etc. In the case of very
3450 large lists of prerequisites this causes problems. Instead reuse
3451 a static buffer (resizeable) for each variable.
3453 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3454 target-specific variable definitions. Check for it and set an
3456 (record_target_var): Set the export field to v_export if the
3457 "exported" flag is set.
3458 * doc/make.texi (Target-specific): Document the ability to use
3461 * doc/make.texi: Change the name of the section on automatic
3462 variables from "Automatic" to "Automatic Variables". Added text
3463 clarifying the scope of automatic variables.
3465 2002-10-04 Paul D. Smith <psmith@gnu.org>
3467 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3469 (record_files): Ditto.
3471 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3472 the search for the '=' to only within the enclosing parens.
3474 2002-10-03 Paul D. Smith <psmith@gnu.org>
3476 Version 3.80 released.
3478 * dir.c: Change hash functions to use K&R function definition style.
3479 * function.c: Ditto.
3481 * variable.c: Ditto.
3483 Update to automake 1.7.
3485 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3486 (pdf): Remove this target as automake now provides one.
3488 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3490 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3492 * makefile.com: Updates for GNU make 3.80.
3493 * makefile.vms: Ditto.
3495 2002-09-23 Paul D. Smith <psmith@gnu.org>
3497 * read.c (enum make_word_type): Remove w_comment.
3498 (get_next_mword): Don't treat comment characters as special; where
3499 this function is used we will never see a comment (it's stripped
3500 before we get here) and treating comments specially means that
3501 targets like "foo\#bar" aren't handled properly.
3503 2002-09-18 Paul D. Smith <psmith@gnu.org>
3505 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3507 * read.c (eval): Expansion of arguments to export/unexport was
3508 ignoring all arguments after the first one. Change the algorithm
3509 to expand the whole line once, then parse the results.
3511 2002-09-17 Paul D. Smith <psmith@gnu.org>
3513 Fix Bug #940 (plus another bug I found while looking at this):
3515 * read.c (record_target_var): enter_file() will add a new entry if
3516 it's a double-colon target: we don't want to do that in this
3517 situation. Invoke lookup_file() and only enter_file() if it does
3518 not already exist. If the file we get back is a double-colon then
3519 add this variable to the "root" double-colon target.
3521 * variable.c (initialize_file_variables): If this file is a
3522 double-colon target but is not the "root" target, then initialize
3523 the root and make the root's variable list the parent of our
3526 2002-09-13 Paul D. Smith <psmith@gnu.org>
3528 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3530 * hash.c (round_up_2): Get rid of a warning.
3532 2002-09-12 Paul D. Smith <psmith@gnu.org>
3534 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3535 so it doesn't complain about getloadavg.c.
3537 * commands.c (set_file_variables): Make sure we always alloca() at
3538 least 1 character for the value of $? (for '\0').
3540 2002-09-11 Paul D. Smith <psmith@gnu.org>
3542 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3543 macro to use RESULT instead of the incorrect _RESULT_.
3545 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3546 and atomic_readdir(). We need to #include dirent.h to get this to
3548 * misc.c (atomic_readdir): Fix typos.
3550 2002-09-10 Paul D. Smith <psmith@gnu.org>
3552 * read.c (eval): Expand variable lists given to export and
3553 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3554 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3556 * doc/make.texi (Variables/Recursion): Document this.
3557 (Conditional Syntax): And here.
3559 2002-09-09 Paul D. Smith <psmith@gnu.org>
3561 * configure.in: Check for memmove().
3563 2002-09-07 Paul D. Smith <psmith@gnu.org>
3565 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3566 Michael Sterrett <msterret@coat.com> reports that while it has
3567 SA_RESTART, it does not work properly.
3569 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3570 that invokes stat() and loops to do it again if it returns EINTR.
3571 (atomic_readdir): Ditto, with readdir().
3573 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3574 and readdir() to atomic_stat() and atomic_readdir().
3576 2002-09-04 Paul D. Smith <psmith@gnu.org>
3578 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3579 reports that GNU make sometimes doesn't recognize that targets can
3580 be made, when directories can be created as prerequisites. He
3581 reports that changing the order of predicates in the DEP->changed
3582 flag test so that lookup_file() is always performed, solves this
3585 2002-08-08 Paul D. Smith <psmith@gnu.org>
3587 * configure.in: Require a newer version of gettext.
3589 * misc.c (perror_with_name): Translate the format string (for
3590 right-to-left language support).
3591 (pfatal_with_name): Ditto.
3593 * main.c: Create a static array of strings to store the usage
3594 text. This is done to facilitate translations.
3595 (struct command_switch): Remove argdesc and description fields.
3596 (switches): Remove values for obsolete fields.
3597 (print_usage): Print each element of the usage array.
3599 * hash.c: Change function definitions to be K&R style.
3601 2002-08-02 Paul D. Smith <psmith@gnu.org>
3603 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3604 this one because it's too hard to get right. We'll look at it for
3606 * main.c (main): Don't create the .TARGETS variable.
3607 * variable.c (handle_special_var): Don't handle .TARGETS.
3609 2002-08-01 Paul D. Smith <psmith@gnu.org>
3611 * main.c (switches): Add a new option, -B (--always-make). If
3612 specified, make will rebuild all targets that it encounters even
3613 if they don't appear to be out of date.
3614 (always_make_flag): New flag.
3615 * make.h: Extern always_make_flag.
3616 * remake.c (update_file_1): Check always_make_flag; if it's set we
3617 will always rebuild any target we can, even if none of its
3618 prerequisites are newer.
3621 * doc/make.texi (Shell Function): Make it clear that make
3622 variables marked as "export" are not passed to instances of the
3625 Add new introspection variable .VARIABLES and .TARGETS.
3627 * variable.c (handle_special_var): New function. If the variable
3628 reference passed in is "special" (.VARIABLES or .TARGETS),
3629 calculate the new value if necessary. .VARIABLES is handled here:

3631 which is a list of the names. .TARGETS is handled by
3632 build_target_list().
3633 (lookup_variable): Invoke handle_special_var().
3634 * file.c (build_target_list): Walk through the hask of known files
3635 and construct a list of the names of all the ones marked as

3638 * doc/make.texi (Special Variables): Document them.
3639 * NEWS: Mention them.
3641 * variable.h (struct variable): Add a new flag "exportable" which
3642 is true if the variable name is valid for export.
3643 * variable.c (define_variable_in_set): Set "exportable" when a new
3644 variable is defined.
3645 (target_environment): Use the "exportable" flag instead of
3646 re-checking the name here... an efficiency improvement.
3648 2002-07-31 Paul D. Smith <psmith@gnu.org>
3650 * config.h-vms.template: Updates to build on VMS. Thanks to
3651 Brian_Benning@aksteel.com for helping verify the build.

3653 * hash.h: Use strcpmi(), not stricmp(), in the
3654 HAVE_CASE_INSENSITIVE_FS case.
3656 2002-07-30 Paul D. Smith <psmith@gnu.org>
3658 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3659 backslashes to the HAVE_CASE_INSENSITIVE_FS case.

3664 * variable.c (pop_variable_scope): Remove variable made unused by
3665 new hash infrastructure.
3666 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3667 comparisons as well as name comparisons.
3668 * variable.h: Add a prototype for new hash_init_function_table().
3669 * file.c (lookup_file): Remove variables made unused by new hash
3671 * dir.c (directory_contents_hash_2): Missing return of hash value.
3672 (dir_contents_file_exists_p): Remove variables made unused by new
3673 hash infrastructure.
3676 Installed Greg McGary's integration of the hash functions from the
3677 GNU id-utils package:
3679 2002-07-10 Greg McGary <greg@mcgary.org>
3681 * scripts/functions/filter-out: Add literals to to the
3682 pattern space in order to add complexity, and trigger
3683 use of an internal hash table. Fix documentation strings.
3684 * scripts/targets/INTERMEDIATE: Reverse order of files
3685 passed to expected `rm' command.

3779 2002-07-10 Paul D. Smith <psmith@gnu.org>
3781 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3782 prerequisite list. A real SysV make will expand the entire
3783 prerequisites list _twice_: we don't do that as it's a big
3784 backward-compatibility problem. We only replace those specific
3787 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3788 references left in the list of prerequisites. Check for .POSIX as
3789 we record targets, so we can disable non-POSIX behavior while
3790 reading makefiles as well as running them.
3791 (eval): Check the prerequisite list to see if we have anything
3792 that looks like a SysV prerequisite variable reference.
3794 2002-07-09 Paul D. Smith <psmith@gnu.org>
3796 * doc/make.texi (Prerequisite Types): Add a new section describing
3797 order-only prerequisites.
3799 * read.c (uniquize_deps): If we have the same file as both a
3800 normal and order-only prereq, get rid of the order-only prereq,
3801 since the normal one supersedes it.
3803 2002-07-08 Paul D. Smith <psmith@gnu.org>
3805 * AUTHORS: Added Greg McGary to the AUTHORS file.
3806 * NEWS: Blurbed order-only prerequisites.
3807 * file.c (print_file): Show order-only deps properly when printing
3810 * maintMakefile: Add "update" targets for wget'ing the latest
3811 versions of various external files. Taken from Makefile.maint in
3814 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3815 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3817 2002-07-07 Paul D. Smith <psmith@gnu.org>
3819 * po/*.po: Remove. We'll use wget to retrieve them at release
3822 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3823 rather than a shell you get an exception. Make sure we look up
3824 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3826 * remake.c (notice_finished_file): Fix handling of -t flag.
3827 Patch provided by Henning Makholm <henning@makholm.net>.
3829 * implicit.c (pattern_search): Some systems apparently run short
3830 of stack space, and using alloca() in this function caused an
3831 overrun. I modified it to use xmalloc() on the two variables
3832 which seemed like they might get large. Fixes Bug #476.
3834 * main.c (print_version): Update copyright notice to conform with
3836 (print_usage): Update help output.
3838 * function.c (func_eval): Create a new make function, $(eval
3839 ...). Expand the arguments, put them into a buffer, then invoke
3840 eval_buffer() on the resulting string.
3841 (func_quote): Create a new function, $(quote VARNAME). Inserts
3842 the value of the variable VARNAME without expanding it any
3845 * read.c (struct ebuffer): Change the linebuffer structure to an
3846 "eval buffer", which can be either a file or a buffer.
3847 (eval_makefile): Move the code in the old read_makefile() which
3848 located a makefile into here: create a struct ebuffer with that
3849 information. Have it invoke the new function eval() with that
3851 (eval_buffer): Create a new function that creates a struct ebuffer
3852 that holds a string buffer instead of a file. Have it invoke
3853 eval() with that ebuffer.
3854 (eval): New function that contains the guts of the old
3855 read_makefile() function: this function parses makefiles. Obtains
3856 data to parse from the provided ebuffer. Some modifications to
3857 make the flow of the function cleaner and clearer. Still could
3858 use some work here...
3859 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3860 contents of the define/endef variable from the ebuffer.
3861 (readstring): Read the next line from a string-style ebuffer.
3862 (readline): Read the next line from an ebuffer. If it's a string
3863 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3866 * dep.h (eval_buffer): Prototype eval_buffer();
3868 * variable.c (do_variable_definition): Make sure that all
3869 non-target-specific variables are registered in the global set.
3870 If we're invoked from an $(eval ...) we might be inside a $(call
3871 ...) or other function which has pushed a variable scope; we still
3872 want to define our variables from evaluated makefile code in the
3875 2002-07-03 Greg McGary <greg@mcgary.org>
3877 * dep.h (struct dep) [ignore_mtime]: New member.
3878 [changed]: convert to a bitfield.
3879 * implicit.c (pattern_search): Zero ignore_mtime.
3880 * main.c (main, handle_non_switch_argument): Likewise.
3881 * rule.c (convert_suffix_rule): Likewise.
3882 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3883 (read_makefile): Parse '|' in prerequisite list.
3884 (uniquize_deps): Consider ignore_mtime when comparing deps.
3885 * remake.c (update_file_1, check_dep): Don't force remake for
3886 dependencies that have d->ignore_mtime.
3887 * commands.c (FILE_LIST_SEPARATOR): New constant.
3888 (set_file_variables): Don't include a
3889 prerequisite in $+, $^ or $? if d->ignore_mtime.
3892 2002-06-18 Paul D. Smith <psmith@gnu.org>
3894 * make.texinfo: Updates for next revision. New date/rev/etc.
3895 Recreate all Info menus. Change license on the manual to the GNU
3896 Free Documentation License. A number of typos.
3897 (Variables Simplify): Don't use "-" before it's defined.
3898 (Automatic Prerequisites): Rewrite the target example to work
3899 properly if the compile fails. Remove incorrect comments about
3900 how "set -e" behaves.
3901 (Text Functions): Move the "word", "wordlist", "words", and
3902 "firstword" functions here, from "File Name Functions".
3903 * make-stds.texi: Update from latest GNU version.
3904 * fdl.texi: (created) Import the latest GNU version.
3906 2002-06-06 Paul D. Smith <psmith@gnu.org>
3908 * variable.c (do_variable_definition): New function: extract the
3909 part of try_variable_definition() that actually sets the value
3910 into a separate function.
3911 (try_variable_definition): Call do_variable_definition() after
3912 parsing the variable definition string.
3913 (define_variable_in_set): Make the name argument const.
3915 * variable.h (enum variable_flavor): Make public.
3916 (do_variable_definition): Create prototype.
3918 * read.c (read_all_makefiles): Create a new built-in variable,
3920 (read_makefile): Add each makefile read in to this variable value.
3922 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3924 * Makefile.DOS.template: Tweak according to changes in the
3925 distribution. Add back the dependencies of *.o files.
3927 * configh.dos.template: Synchronize with config.h.in.
3929 2002-05-09 Paul D. Smith <psmith@gnu.org>
3931 * file.c (file_timestamp_now): Use K&R function declaration.
3933 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3934 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3935 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3936 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3937 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3938 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3939 nlist.n_name is a pointer rather than an array.
3941 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3942 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3943 * configure.in: Use it instead of the old version.
3945 * main.c (main): Prefer setvbuf() to setlinebuf().
3947 2002-05-08 Paul D. Smith <psmith@gnu.org>
3949 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3950 (loadavg_LDADD): Ditto.
3952 2002-04-29 Paul D. Smith <psmith@gnu.org>
3954 * expand.c (recursively_expand_for_file): Rename
3955 recursively_expand() to recursively_expand_for_file() and provide
3956 an extra argument, struct file. If the argument is provided, set
3957 the variable scope to that of the file before expanding.
3958 * variable.h (recursively_expand): Make this a macro that invokes
3959 recursively_expand_for_file() with a NULL file pointer.
3960 * variable.c (target_environment): Call the renamed function and
3961 provide the current file context.
3962 Fixes Debian bug #144306.
3964 2002-04-28 Paul D. Smith <psmith@gnu.org>
3966 Allow $(call ...) user-defined variables to be self-referencing
3967 without throwing an error. Allows implementation of transitive
3968 closures, among other possibly useful things.
3969 Requested by: Philip Guenther <guenther@sendmail.com>
3971 * variable.h (struct variable): Add a new field: exp_count, and
3972 new macros to hold its size and maximum value.
3973 (warn_undefined): Make this a macro.
3974 * variable.c (define_variable_in_set): Initialize it.
3975 * expand.c (recursively_expand): If we detect recursive expansion
3976 of a variable, check the exp_count field. If it's greater than 0
3977 allow the recursion and decrement the count.
3978 (warn_undefined): Remove this (now a macro in variable.h).
3979 * function.c (func_call): Before we expand the user-defined
3980 function, modify its exp_count field to contain the maximum
3981 number of recursive calls we'll allow. After the call, reset it
3984 2002-04-21 Paul D. Smith <psmith@gnu.org>
3986 Modified to use latest autoconf (2.53), automake (1.6.1), and
3987 gettext (0.11.1). We're using gettext's new "external" support,
3988 to avoid including libintl source with GNU make.
3990 * README.cvs: New file. Explain how to build GNU make from CVS.
3992 * configure.in: Modify checking for the system glob library.
3993 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3994 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3995 etc. will manage it correctly). Set an automake conditional
3996 USE_LOCAL_GLOB to decide whether to compile the glob library.
3998 * getloadavg.c (main): Include make.h in the "TEST" program to
4001 * Makefile.am: Remove special rules for loadavg. Replace them
4002 with Automake capabilities for building extra programs.
4004 * signame.c: This file does nothing if the system provide
4005 strsignal(). If not, it implements strsignal(). If the system
4006 doesn't define sys_siglist, then we make our own; otherwise we use
4008 * signame.h: Removed.
4010 * main.c (main): No need to invoke signame_init(). Update copyright.
4012 * ABOUT-NLS: Removed.
4013 * gettext.c: Removed.
4014 * gettext.h: Get a simplified copy from the gettext package.
4016 * i18n/*.po: Moved to po/.
4019 * config/*: Created. Contains package configuration helper files.
4020 * config.guess, config.sub: Moved to config directory.
4022 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4023 Rework to use new-style autoconf features. Use the "external"
4024 mode for gettext. Make the build.sh config file conditional on
4025 whether build.sh.in exists, to avoid autoconf errors.
4026 * acinclude.m4: Removed almost all macros as being obsolete.
4027 Rewrote remaining macros to use AC_DEFINE.
4028 * acconfig.h: Removed.
4030 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4031 conditional to handle customs support. Remove special handling
4034 2002-04-20 Paul D. Smith <psmith@gnu.org>
4036 * function.c (func_call): Don't mark the argument variables $1,
4037 etc. as recursive. They've already been fully expanded so
4038 there's no need to do it again, and doing so strips escaped $'s.
4039 Reported by Sebastian Glita <glseba@yahoo.com>.
4041 * remake.c (notice_finished_file): Walk through double-colon
4042 entries via the prev field, not the next field!
4043 Reported by Greg McGary <greg@mcgary.org>.
4045 * main.c (main): If the user specifies -q and asks for a specific
4046 target which is a makefile, we got an assert. In that case it
4047 turns out we should continue normally instead.
4049 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4051 * i18n/he.po: Installed a new translation.
4053 2002-01-07 Paul D. Smith <psmith@gnu.org>

4059 * i18n/ja.po: Installed an updated translation.
4061 2001-09-06 Paul Eggert <eggert@twinsun.com>
4063 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4064 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4066 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4068 (main): Get rid of any avoidable limit on stack size.
4070 2001-09-04 Paul D. Smith <psmith@gnu.org>

4086 * i18n/ko.po: Installed a new translation.
4088 2001-05-06 Paul D. Smith <psmith@gnu.org>
4090 Modify the EINTR handling.
4092 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4093 the way in which we manage the file descriptor/signal handler race
4094 trap to be more efficient.
4096 2001-05-06 Paul Eggert <eggert@twinsun.com>
4098 Restart almost all system calls that are interrupted, instead
4099 of worrying about EINTR. The lone exception is the read() for
4102 * configure.in (HAVE_SA_RESTART): New macro.
4103 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4104 * main.c (main): Use SA_RESTART instead of the old,
4105 nonstandard SA_INTERRUPT.
4107 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4108 * main.c (bsd_signal): New function or macro,
4109 if the implementation doesn't supply it.
4110 (The bsd_signal function will be in POSIX 1003.1-200x.)
4111 (HANDLESIG): Remove.
4112 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4114 * make.h (EINTR_SET): Remove.
4115 (SA_RESTART): New macro.
4117 * arscan.c (ar_member_touch): Don't worry about EINTR.
4118 * function.c (func_shell): Likewise.
4119 * job.c (reap_children, free_child, new_job): Likewise.
4120 * main.c (main): Likewise.
4121 * remake.c (touch_file, name_mtime): Likewise.
4123 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4124 if fstat failed with errno!=EINTR, the error was ignored.
4126 * job.c (set_child_handler_action_flags): New function.
4127 (new_job): Use it to temporarily clear the SIGCHLD action flags
4128 while reading the token.
4130 2001-05-02 Paul D. Smith <psmith@gnu.org>
4132 * job.c (start_job_command): Don't add define/endef per-line flags
4133 to the top-level flags setting.
4135 2001-04-03 Paul D. Smith <psmith@gnu.org>
4137 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4138 bit on error, so check for odd return values, not non-0 return
4140 (VMS_get_member_info): Calculate the timezone differences correctly.
4141 Reported by John Fowler <jfowler@nyx.net>.
4144 2001-03-14 Paul D. Smith <psmith@gnu.org>
4146 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4147 value before invoking define_variable().
4148 Reported by John Fowler <jfowler@nyx.net>.
4150 2001-02-07 Paul D. Smith <psmith@gnu.org>
4152 * read.c (record_target_var): If we reset the variable due to a
4153 command-line variable setting overriding it, turn off the "append"
4156 2001-01-17 Paul D. Smith <psmith@gnu.org>
4158 * variable.c (lookup_variable) [VMS]: When getting values from the
4159 environment, allocate enough space for the _value_ plus escapes,
4160 not enough space for the name plus escapes :-/.
4161 Reported by John Fowler <jfowler@nyx.net>.
4163 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4164 warnings that make generates, so it doesn't look like an error.
4165 Reported by Karl Berry <karl@gnu.org>.
4168 Fix for PR/2020: Rework appended target-specific variables. I'm
4169 fairly confident this algorithm is finally correct.
4171 * expand.c (allocated_variable_append): Rewrite. Instead of
4172 expanding each appended variable then adding all the expanded
4173 strings together, we append all the unexpanded values going up
4174 through the variable set contexts, then expand the final result.
4175 This behaves just like non-target-specific appended variable
4176 values, while the old way didn't in various corner cases.
4177 (variable_append): New function: recursively append the unexpanded
4178 value of a variable, walking from the outermost variable scope to
4180 * variable.c (lookup_variable): Remove the code that looked up the
4181 variable set list if the found variable was "append". We don't
4183 (lookup_variable_in_set): Make this non-static so we can use it
4185 (try_variable_definition): Use lookup_variable_in_set() rather
4186 than faking out current_variable_set_list by hand (cleanup).
4187 * variable.h: Add a prototype for the now non-static
4188 lookup_variable_in_set().
4190 2000-11-17 Paul D. Smith <psmith@gnu.org>
4192 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4193 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4194 before throwing a fit.
4196 2000-11-17 Paul D. Smith <psmith@gnu.org>
4198 * read.c (readline): CRLF calculations had a hole, if you hit the
4199 buffer grow scenario just right. Reworked the algorithm to avoid
4200 the need for len or lastlen at all. Problem description with
4201 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4203 2000-10-24 Paul D. Smith <psmith@gnu.org>
4205 * gettext.c (SWAP): Declare this with the prototype, otherwise
4206 some systems don't work (non-32-bit? Reported for Cray T3E).
4207 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4209 2000-10-05 Paul D. Smith <psmith@gnu.org>
4211 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4212 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4214 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4216 2000-09-22 Paul D. Smith <psmith@gnu.org>
4218 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4219 parts of the real gettext.h here, and we expect to really include
4220 the real gettext.h later. If we keep this #define, it's ignored.
4222 2000-09-21 Paul D. Smith <psmith@gnu.org>
4224 * main.c (log_working_directory): Rework the text to use complete
4225 sentences, to make life simpler for the translators.
4227 2000-08-29 Paul D. Smith <psmith@gnu.org>
4229 * file.c (remove_intermediates): Print a debug message before we
4230 remove intermediate files, so the user (if she uses -d) knows
4233 2000-08-21 Paul D. Smith <psmith@gnu.org>
4235 * variable.c (try_variable_definition): Change how we handle
4236 target-specific append variable defns: instead of just setting the
4237 value, expand it as an append _but_ only within the current
4238 target's context. Otherwise we lose all but the last value if the
4239 variable is appended more than once within the current target
4240 context. Fixes PR/1831.
4242 2000-08-16 Paul D. Smith <psmith@gnu.org>
4244 * function.c (func_shell): Nul-terminate the buffer before
4245 printing an exec error message (just in case it's not!).
4246 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4248 2000-07-25 Paul D. Smith <psmith@gnu.org>
4250 * job.c (construct_command_argv_internal): Add "~" to the list of
4251 sh_chars[] which disallow optimizing out the shell call.
4253 2000-07-23 Paul Eggert <eggert@twinsun.com>
4255 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4256 supersedes --disable-nsec-timestamps.
4257 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4258 * README: Remove --disable-nsec-timestamps.
4260 * filedef.h (struct file.low_resolution_time): New member.
4261 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4262 * remake.c (update_file_1):
4263 Avoid spurious rebuilds due to low resolution time stamps,
4264 generalizing the earlier code that applied only to archive members.
4265 (f_mtime): Archive members always have low resolution time stamps.
4267 * configure.in: Remove --disable-nsec-timestamps, as this has
4268 been superseded by .LOW_RESOLUTION_TIME.
4270 2000-07-23 Paul Eggert <eggert@twinsun.com>
4272 * configure.in (enable_nsec_timestamps): Renamed from
4273 make_cv_nsec_timestamps, since enable/disable options
4274 shouldn't be cached.
4276 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4277 and Paul Eggert <eggert@twinsun.com>
4279 * file.c (file_timestamp_now):
4280 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4281 so that clock_gettime is not linked unless needed.
4283 * filedef.h (FILE_TIMESTAMP_HI_RES):
4284 Remove definition; "configure" now does this.
4286 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4287 to before high resolution file timestamp check,
4288 since that check now uses uintmax_t.
4289 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4290 high resolution file timestamps.
4291 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4292 so that we don't link in clock_gettime unnecessarily.
4294 2000-07-17 Paul D. Smith <psmith@gnu.org>
4296 * i18n/ja.po: New version of the translation file.
4298 2000-07-07 Paul D. Smith <psmith@gnu.org>
4300 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4301 the offset calculation.
4302 (name_mtime): Replace EINTR test with EINTR_SET macro.
4304 2000-07-07 Paul Eggert <eggert@twinsun.com>
4308 * remake.c (update_file_1):
4309 Avoid spurious rebuilds of archive members due to their
4310 timestamp resolution being only one second.
4311 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4312 the clock's resolution being lower than file timestamps'.
4313 When warning about future timestamps, report only the discrepancy,
4314 not the absolute value of the timestamp and the current time.
4316 * file.c (file_timestamp_now): New arg RESOLUTION.
4317 * filedef.h (file_timestamp_now): Likewise.
4318 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4320 2000-07-05 Paul D. Smith <psmith@gnu.org>
4322 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4323 to listp. Fixes PR/1793.
4325 2000-06-26 Paul Eggert <eggert@twinsun.com>
4327 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4329 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4331 * remake.c (f_mtime): Remove unused var memtime.
4333 2000-06-25 Martin Buchholz <martin@xemacs.org>
4335 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4336 Ran spell-check on make.texinfo.
4338 2000-06-23 Paul D. Smith <psmith@gnu.org>
4340 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4341 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4342 * make.h: Define these macros.
4344 * Version 3.79.1 released.
4346 * configure.in: Add a new option, --disable-nsec-timestamps, to
4347 avoid using sub-second timestamps on systems that support it. It
4348 can lead to problems, e.g. if your makefile relies on "cp -p".
4349 * README.template: Document the issue with "cp -p".
4351 * config.guess, config.sub: Updated.
