562 2009-11-12 Boris Kolpackov <boris@codesynthesis.com>
564 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
565 which allows the caller to get the index of the matching directory.
567 * make.h (vpath_search): Update prototype.
569 * remake.c (library_search): Implement linker-compatible library
570 search. Use the new VPATH_SEARCH index functionality to keep track
571 of the directory index for each match. Select the match with the
572 lowest directory index.
574 * implicit.c (pattern_search): Pass NULL for the index arguments in
575 the VPATH_SEARCH call.
577 * doc/make.texi (Directory Search for Link Libraries): Describe the
580 * NEWS: Add a note about the new behavior.
582 2009-10-25 Paul Smith <psmith@gnu.org>
584 * AUTHORS, et.al.: Update copyright years.
586 * implicit.c (stemlen_compare): Fix qsort() compare bug that
587 caused implicit rules with equal stem lengths to be sorted
590 2009-10-24 Paul Smith <psmith@gnu.org>
592 * main.c (usage): Add --eval to the usage string.
593 (switches): Add the --eval switch.
594 (main): If --eval is given, add them to the simply-expanded variable
595 -*-eval-flags-*- (necessary to allow recursion to work properly).
596 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
598 * NEWS: Describe the new --eval command line argument.
599 * doc/make.texi (Options Summary): Document --eval.

602 * read.c (eval_buffer): Ditto.
605 * variable.h (define_variable_cname): New macro for constant
607 * default.c (set_default_suffixes): Use it.
608 * main.c (main): Ditto.

623 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
625 * read.c (do_undefine): Free the expanded variable name.
627 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
628 to normal upgrade logic from dep_hash_cmp to set_file_variables.
630 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
632 * dep.h (uniquize_deps): Remove.
634 * read.c (uniquize_deps): Merge into set_file_variables in
636 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
638 * commands.c (set_file_variables): Avoid modifying the dep
639 chain to achieve uniqueness. Fixes savannah bug 25780.
641 * implicit.c (pattern_search): Instead of re-setting all automatic
642 variables for each rule we try, just update $*.
644 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
646 * variable.h (undefine_variable_in_set): New function declaration.
647 (undefine_variable_global): New macro.
649 * variable.c (undefine_variable_in_set): New function implementation.
651 * read.c (vmodifiers): Add undefine_v modifier.

660 * NEWS: Add a note about the new directive.
662 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
664 * implicit.c (pattern_search): Initialize file variables only
665 if we need to parse a rule that requires the second expansion.
667 2009-10-03 Paul Smith <psmith@gnu.org>
669 * make.h: Include <alloca.h> even on systems where __GNUC__ is
670 defined. Not sure why it was done the other way.
671 Requested by David Boyce <dsb@boyski.com>.
673 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
675 * dep.h (dep): Add the DONTCARE bitfield.
677 * filedef.h (file):Add the NO_DIAG bitfield.
679 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
680 not struct file (a file can be a dependency of many targets,
681 some don't care, some do).
683 * remake.c (update_goal_chain): Propagate DONTCARE from struct
684 dep to struct file before updating the goal and restore it
686 (update_file): Don't prune the dependency graph if this target
687 has failed but the diagnostics hasn't been issued.
688 (complain): Scan the file's dependency graph to find the file
689 that caused the failure.
690 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
691 whether to print diagnostics.
693 Fixes Savannah bugs #15110, #25493, #12686, and #17740.

703 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
704 much of the command line on a single pass.
706 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
708 * varible.c (create_pattern_var): Insert variables into the
709 PATTERN_VARS list in the shortest patterns first order.

726 2009-09-27 Paul Smith <psmith@gnu.org>
728 * doc/make.texi (Double-Colon): Mention that pattern rules with
729 double-colons have a different meaning. Savannah bug #27497.
731 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
733 * configh.dos.template: Remove unconditional definition of
734 SYS_SIGLIST_DECLARED.
735 Include <sys/version.h> because ports of GCC 4.3.0 and later no
736 longer include it, so macros like __DJGPP_MINOR__ are no longer
737 defined automatically.
739 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
740 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
741 instead of using the hardcoded ones.
742 (SUBDIRS): doc subdir added.
743 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
744 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
745 create html formated docs. texi2html may not be ported to DOS.
746 (make.info, make.dvi, make.ps, make.html): Make targets depend on
748 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
749 -I switch to look in ./ instead of ./doc.
750 (html): Target depend on html-recursive instead of make_1.html.
751 (make_1.html): Removed.
752 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
753 (all-recursive): Allow for more than one subdir in the build
755 (mostlyclean-recursive, clean-recursive, distclean-recursive)
756 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
757 (tags-recursive): Allow for more than one subdir in the build
759 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
760 targets. Enter into doc/ to produce the targets.
761 (all-am): $(INFO_DEPS) replaced by info.
763 2009-09-26 Paul Smith <psmith@gnu.org>
765 * read.c (record_files): Use free_ns() to free struct nameseq.
768 * rule.c (freerule): Use free_dep_chain().
770 * read.c (record_files): Free FILENAMES chain for implicit rules.
771 (eval): Static pattern targets go into the string cache.
773 * function.c (string_glob): Free NAME in the nameseq chain.
775 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
777 * implicit.c (pattern_search): Terminate early if we haven't
778 found any rules to try (performance improvement).
780 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
782 * implicit.c (pattern_search): Merge three parallel arrays,
783 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
784 of struct TRYRULE. In the old version the latter two arrays
785 had insufficient length.
787 2009-09-24 Paul Smith <psmith@gnu.org>
789 * implicit.c (pattern_search): Add back support for order-only
790 prerequisites for secondary expansion implicit rules, that were
791 accidentally dropped. If we find a "|", enable order-only mode
792 and set IGNORE_MTIME on all deps that are seen afterward.
793 (pattern_search): Fix memory leaks: for intermediate files where
794 we've already set the file variable and pattern variable sets, be
795 sure to either save or free them as appropriate.
797 2009-09-23 Paul Smith <psmith@gnu.org>
799 Rework the way secondary expansion is stored, for efficiency.
800 This changes secondary expansion so that ONLY WHEN we know we have
801 a possibility of needing secondary expansion, do we defer the
802 secondary expansion. This means more parsing the deps but we use
803 a lot less memory (due to the strcache). Also, this fixes
806 * read.c (eval): Don't parse the dep string here anymore.
807 (record_files): Take the dep argument as an unparsed string. If
808 secondary expansion is enabled AND the prereq string has a '$' in
809 it, then set NEED_2ND_EXPANSION and keep the entire string.
810 Otherwise, parse the dep string here to construct the dep list
811 with the names in the strcache.
813 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
814 duplicate the name string (others are in the strcache).
816 * implicit.c: Remove struct idep and free_idep_chain(): unused.
817 (struct patdeps): New structure to store prereq information.
818 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
819 which prerequisites need expansion, and expand only those.
821 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
822 and enter_prereqs(). split_prereqs() takes a fully-expanded string
823 and splits it into a DEP list, handling order-only prereqs.
824 (enter_prereqs): This function enters a list of DEPs into the file
825 database. If there's a stem defined, expand any pattern chars.
826 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
827 set. Use the above functions.
828 (snap_deps): Only perform second expansion on prereqs that need it,
829 as defined by the NEED_2ND_EXPANSION flag.
830 (print_prereqs): New function to print the prereqs
831 (print_file): Call print_prereqs() rather than print inline.
833 * hash.h (STRING_COMPARE): Take advantage of strcache() by
835 (STRING_N_COMPARE): Ditto.
836 (ISTRING_COMPARE): Ditto.
838 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
839 (parse_file_seq): Return void*
840 * read.c (parse_file_seq): Return void*.
841 (eval): Invoke macroized version of parse_file_seq()
842 * default.c (set_default_suffixes): Ditto.
843 * file.c (split_prereqs): Ditto.
844 * function.c (string_glob): Ditto.
845 * main.c (main): Ditto.
846 * rule.c (install_pattern_rule): Ditto.
848 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
850 2009-09-16 Paul Smith <psmith@gnu.org>
852 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
854 * dep.h: Create alloc_dep() / free_dep() macros.
856 * implicit.c (pattern_search): Take advantage of the new
857 parse_file_seq() to add the directory prefix to each prereq.
859 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
860 all. Avoid reversing chains. Support adding prefixes.
861 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
862 cached/non-cached results.
863 (eval): Remove multi_glob() & invoke new parse_file_seq().
864 * rule.c (install_pattern_rule): Ditto.
865 * main.c (main): Ditto.
866 * implicit.c (pattern_search): Ditto.
867 * function.c (string_glob): Ditto.
868 * file.c (parse_prereqs): Ditto.
869 * default.c (set_default_suffixes): Ditto.
871 * variable.c (parse_variable_definition): Don't run off the end of
872 the string if it ends in whitespace (found with valgrind).
874 * commands.c (set_file_variables): Keep space for all targets in
875 $? if -B is given (found with valgrind).
877 2009-09-15 Paul Smith <psmith@gnu.org>
879 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
880 (xcalloc): Add new function.
881 * make.h: New declarations.
883 * ar.c (ar_glob_match): New calling method for concat().
884 * main.c (main): Ditto.
885 (decode_env_switches): Ditto.
886 * read.c (eval_makefile): Ditto.
887 (tilde_expand): Ditto.
888 (parse_file_seq): Ditto.
889 * variable.c (target_environment): Ditto.
890 (sync_Path_environment): Ditto.
892 * ar.c (ar_glob_match): Use xcalloc().
893 * dir.c (file_impossible): Ditto.
894 * file.c (enter_file): Ditto.
895 * job.c (new_job): Ditto.
896 * read.c (parse_file_seq): Ditto.
897 * vmsfunctions.c (opendir): Ditto.
899 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
901 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
902 inside the loop that looks up environment for PATH.
904 2009-08-31 Eli Zaretskii <eliz@gnu.org>
906 * function.c (windows32_openpipe): Update envp after calling
907 sync_Path_environment.
909 2009-08-02 Paul Smith <psmith@gnu.org>
911 * remake.c (notice_finished_file): Ensure file->cmds is not null
912 before looping through them. Fixes Savannah bug #21824.
914 * doc/make.texi (Wildcard Examples): Clarify when objects is
915 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
916 (Include): Clarify the behavior of -include.
917 Fixes Savannah bug #18963.
919 2009-08-01 Paul Smith <psmith@gnu.org>
921 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
922 etc. come on the command line. Fixes Savannah bug #27093.
924 * expand.c (expand_argument): If the argument is large enough use
925 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
927 * variable.c (do_variable_definition): Avoid using alloca() to
928 hold values, which can be large. Fixes Savannah bug #23960.
930 * job.c (new_job): Use memmove() instead of strcpy() since both
931 pointers are in the same memory block. Fixes Savannah bug #27148.
932 Patch by Petr Machata.
934 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
936 * job.c (construct_command_argv_internal): Add "ulimit" and
937 "unset" to the sh_cmds for Unixy shells.
939 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
941 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
942 that set make_cv_sys_gnu_glob, so they are also correctly set
943 when the cache has been populated before.
945 2009-07-04 Eli Zaretskii <eliz@gnu.org>
947 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
948 exist, as realpath(3) does where it's supported.
950 2006-07-04 Eli Zaretskii <eliz@gnu.org>
952 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
953 (abspath): Support systems that define HAVE_DOS_PATHS (have
954 drive letters in their file names). Use IS_PATHSEP instead of a
955 literal '/' comparison. Fixes Savannah bug #26886.
957 2009-06-14 Paul Smith <psmith@gnu.org>
959 * remake.c (update_file_1): Remember the original file we marked
960 as updating, so we can clear that flag again. If we find a target
961 via vpath, FILE might change.
962 (check_dep): Ditto. Fixes Savannah bug #13529.
963 Patch by Reid Madsen <reid.madsen@tek.com>.
965 2009-06-13 Paul Smith <psmith@gnu.org>
967 * doc/make.texi (MAKEFILES Variable): Be explicit that files
968 included by MAKEFILES cannot give default goals.
969 * read.c (eval): If set_default is not set, pass the no-default-goal
970 value when we read included makefiles. Fixes Savannah bug #13401.
972 * ar.c (ar_name): Ensure that targets with empty parens aren't
973 considered archive member references: archive members must have a
974 non-empty "member" string. Fixes Savannah bug #18435.
976 * function.c (string_glob): Rely on multi_glob() to determine
977 whether files exist or not. Remove call to file_exists_p() which
978 is not always correct. Fixes Savannah bug #21231.
979 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
980 then only files that really exist will be returned.
981 * dep.h: Add new argument to multi_glob().
982 * rule.c (install_pattern_rule): Ditto.
983 * read.c (eval): Ditto.
984 * main.c (main): Ditto.
985 * implicit.c (pattern_search): Ditto.
986 * file.c (parse_prereqs): Ditto.
987 * default.c (set_default_suffixes): Ditto.
989 2009-06-09 Paul Smith <psmith@gnu.org>
991 * commands.c (set_file_variables): If always_make_flag is set,
992 always add the prereq to $?. Fixes Savannah bug #17825.
994 * remake.c (update_file_1): When rebuilding deps of FILE, also try
995 to rebuild the deps of all the also_make targets for that file.
996 Fixes Savannah bug #19108.
998 * implicit.c (pattern_search): Undo test for is_target, added by
999 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1000 Rule Search Algorithm". Fixes Savannah bug #17752.
1002 * main.c (clean_jobserver): Clear the jobserver_fds options and
1003 set job_slots to the default when we clean up.
1004 (define_makeflags): Return the new MAKEFLAGS value.
1005 (main): Reset MAKEFLAGS in the environment when we re-exec.
1006 Fixes Savannah bug #18124.
1008 2009-06-08 Paul Smith <psmith@gnu.org>
1010 * read.c (eval): Collapse continuations post-semicolon on target-
1011 specific variables. Fixes Savannah bug #17521.
1013 2009-06-07 Paul Smith <psmith@gnu.org>
1015 * job.c (reap_children): For older systems without waitpid() (are
1016 there any of these left?) run wait(2) inside EINTRLOOP to handle
1017 EINTR errors. Fixes Savannah bug #16401.
1019 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1021 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1023 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1024 not the end, to catch second expansion $(eval ...) defining new
1025 target/prereq relationships during snap_deps.
1026 Fixes Savannah bug #24622.
1028 * read.c (record_files): The second-expansion "f->updating" hack
1029 was not completely correct: if assumed that the target with
1030 commands always had prerequisites; if one didn't then the ordering
1031 was messed up. Fixed for now to use f->updating to decide whether
1032 to preserve the last element in the deps list... but this whole
1033 area of constructing and reversing the deps list is too confusing
1034 and needs to be reworked. Fixes Savannah bug #21198.
1036 2009-06-06 Paul Smith <psmith@gnu.org>
1038 * hash.c (hash_insert): Remove useless test for NULL.
1039 Fixes Savannah bug #21823.
1041 * make.h: Move SET_STACK_SIZE determination to make.h.
1042 * main.c (main): New global variable, STACK_LIMIT, holds the
1043 original stack limit when make was started.
1044 * job.c (start_job_command): Reset the stack limit, if we changed it.
1045 Fixes Savannah bug #22010.
1047 * remake.c (check_dep): Only set the target's state to not-started
1048 if it's not already running. Found this while testing -j10 builds
1049 of glibc: various targets were being rebuilt multiple times.
1050 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1053 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1054 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1057 2009-06-04 Paul Smith <psmith@gnu.org>
1059 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1061 * maintMakefile: Modify access of config and gnulib Savannah
1062 modules to use GIT instead of CVS.

1065 Fixes Savannah bug #24655.
1067 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1068 this can happen during some invocations of $(eval ...) for example.
1069 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1071 2009-06-02 Paul Smith <psmith@gnu.org>
1073 * configure.in: Check for fileno()
1074 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1075 for the makefile file so invocations of $(shell ...) don't inherit it.
1076 Fixes Savannah bug #24277.
1078 2009-06-01 Paul Smith <psmith@gnu.org>
1080 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1081 expansion was handled incorrectly. Rework the default goal
1082 handling to save the variable only. Remove default_goal_file and
1084 * read.c (eval): Check default_goal_var, not default_goal_name.
1085 * read.c (record_target_var): Don't check default_goal_file here.
1087 2009-05-31 Paul Smith <psmith@gnu.org>
1089 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1090 it, and if the multi_glob() returns nothing (say it expanded to
1091 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1093 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1094 $(and ..) to the reference. Fixes Savannah bug #25694.
1096 * make.1: Be clear that some recipes will be executed even with -n.
1097 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1099 * doc/make.texi (Override Directive): Make more clear how
1100 overrides and appends interact.
1101 Elucidates part of Savannah bug #26207.
1103 * read.c (record_target_var): Don't reset the origin on
1104 target-specific variables; try_variable_definition() will handle
1105 this correctly. Fixes Savannah bug #26207.
1107 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1108 Fixes Savannah bug #25712.
1110 * implicit.c (pattern_search): Keep a pointer to the beginning of
1111 the filename and save that instead of the constructed pointer.
1112 Fixes Savannah bug #26593.
1113 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1115 2009-05-30 Paul Smith <psmith@gnu.org>
1117 * doc/make.texi (Multi-Line): Add a description of the new abilities
1118 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1119 "command sequence" vs. "recipe" syntax.
1120 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1121 after a define, to create variables with those flavors.
1123 2009-05-25 Paul Smith <psmith@gnu.org>
1125 Reworked the parser for variable assignments to allow multiple
1126 modifiers, and in any order. Also allows variable and
1127 prerequisites to be modifier names ('export', 'private', etc.)
1129 * NEWS: Add notes about user-visible changes.
1131 * read.c (struct vmodifiers): Remember what modifiers were seen.
1132 (parse_var_assignment): New function to parse variable assignments.
1133 (eval): Call the new function. Handle variable assignments earlier.
1135 * variable.c (parse_variable_definition): Only parse; don't create var.
1136 (assign_variable_definition): Call parse, then create the var.
1138 2009-05-24 Paul Smith <psmith@gnu.org>
1140 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1141 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.

1148 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1149 prototype for xmalloc.
1150 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1151 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1152 Loop over an array of extensions, instead of duplicating the same
1153 code inline. Use SearchPath followed by CreateFile, instead of
1154 the obsolete OpenFile. Fixes Savannah bug #17277.
1155 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1156 to `find_file'. Fixes Savannah bug #25662.
1158 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1160 * function.c (func_shell): Don't close pipedes[1] if it is -1.

1165 * doc/make.texi (Instead of Execution): Document interaction of
1166 -t with phony targets.
1168 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1170 Introduce a new keyword "private" which applies to target-specific
1171 variables and prevents their values from being inherited.

1199 * w32/subproc/build.bat (GCCBuild): Likewise.
1201 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1203 * job.c (construct_command_argv_internal): Avoid extra backslash
1204 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1207 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1209 * README.W32.template: Remove obsolete text about non-support for
1210 -jN without Unixy shell. Remove obsolete text about not supplying
1211 Visual Studio project files (we do supply them). Modify text to
1212 prefer GCC builds to MSC builds.

1233 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1235 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1237 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1238 (TEXINFOS): Value changed to `doc/make.texi'.
1239 (.SUFFIXES): Use .texi instead of .texinfo.
1240 (make.info, make.dvi): Depend on doc/make.texi.
1241 (.texi.info): New target, instead of ".texinfo.info". Change -I
1242 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1243 (.texi): New target, instead of ".texinfo". Change -I switch to
1244 $(MAKEINFO) to look in doc/. Use --no-split.
1245 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1246 switch to $(MAKEINFO) to look in doc/.
1247 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1248 "*.i[0-9][0-9]" (due to --no-split above).
1249 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1250 (html, make_1.html): New targets.
1251 (.PHONY): Add "html".
1252 (.SUFFIXES): Add .html.
1254 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1256 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1257 HAVE_DECL_SYS_SIGLIST.
1259 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1260 build does not use child_execute_job.
1262 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1263 export the SHELL environment variable to the child.
1265 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1267 * config.h.W32: Include sys/types.h.
1268 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1270 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1271 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1274 2007-11-04 Paul Smith <psmith@gnu.org>
1276 * doc/make.texi: Convert references to "commands", "command
1277 lines", and "command script" to "recipe".
1279 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1282 2007-10-27 Bruno Haible <bruno@clisp.org>
1284 * remake.c (f_mtime): Print time difference values between 100 and
1285 ULONG_MAX in fixed-point notation rather than in exponention notation.
1287 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1289 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1290 a more complex value than a simple shell: if it's not a default
1291 shell now then expand it and see if is a default shell then.
1293 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1295 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1296 pathnames, with const strings.
1297 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1298 from the template (used for building from CVS, not a dist).
1300 2007-10-10 Paul Smith <psmith@gnu.org>
1302 * make.h: Add a prototype for w32_kill() (change suggested by

1305 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1307 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1308 directories in Path.
1310 2007-09-12 Paul Smith <psmith@gnu.org>
1312 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1313 Provided by Diego Biurrun <diego@biurrun.de>

1315 Provided by Diego Biurrun <diego@biurrun.de>
1317 2007-09-11 Paul Smith <psmith@gnu.org>
1319 * doc/make.texi (Special Variables): Moved this into the "How to
1320 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1321 (MAKEFILE_LIST) No longer a section; this was added into the
1322 "Special Variables" section.
1323 (Rule Introduction): Reference .RECIPEPREFIX.
1324 (Simple Makefile): Ditto.
1325 (Rule Syntax): Ditto.
1326 (Command Syntax): Ditto.
1327 (Error Messages): Ditto.
1329 2007-09-10 Paul Smith <psmith@gnu.org>
1331 * commands.c (print_commands): Don't print an extra line in the
1332 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1334 * read.c (construct_include_path): Add the full string to the cache; we
1335 were chopping the last char.
1337 * NEWS: Announce the .RECIPEPREFIX special variable.
1338 * variable.c (lookup_special_var): Rename from handle_special_var().
1339 (lookup_variable): Call the new name.
1340 (set_special_var): New function: handle setting of special variables.
1341 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1342 (do_variable_definition): Call it.
1343 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1344 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1345 * main.c (main): Create the .RECIPEPREFIX special variable.
1346 * read.c (eval): Remove the cmd_prefix characters from the command
1347 scripts here, so they're not stored in the commands array at all,
1348 rather than waiting and stripping them out during command construction.
1349 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1351 2007-08-15 Paul Smith <psmith@gnu.org>
1353 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1354 file has had the section info removed, so add some to make.texi
1355 before we include it.
1357 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1359 * remake.c (check_dep): Reset the target state for intermediate
1360 files. They might have been considered before but not updated
1361 then (order-only for example) but they will be this time.
1362 Fixes Savannah bug #'s 3330 and 15919.
1364 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1366 Fix Savannah bug #20549:
1367 * function.c (func_shell): Call construct_command_argv with zero
1369 * job.c (construct_command_argv_internal): New argument FLAGS; all

1373 * job.h (construct_command_argv_internal): Update prototype.
1375 2007-07-13 Paul Smith <psmith@gnu.org>
1377 * file.c (expand_deps): Use variable_buffer as the start of the
1378 buffer, not the original pointer (in case it was reallocated).
1379 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1380 Fixes Savannah bug #20452.
1382 2007-07-04 Paul Smith <psmith@gnu.org>
1384 * (ALL FILES): Update to GPLv3.
1385 * (ALL FILES): Update copyright for 2007.

1389 2007-06-29 Thiemo Seufer <ths@mips.com>
1391 * maintMakefile: Update Translation Project location.
1393 2007-06-13 Paul Smith <psmith@gnu.org>
1395 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1396 "Expansion of a deferred"
1397 Fixes Savannah bug #20018.
1399 * expand.c (variable_expand_for_file): Preserve the value of
1400 reading_file rather than setting it to 0 at the end.

1403 2007-05-11 Paul Smith <psmith@gnu.org>
1405 * job.c (new_job): Add debug info to specify where make found the
1406 command script it is running to build a target.
1407 Fixes Savannah bug #18617.
1409 * default.c (default_suffixes,default_suffix_rules,default_variables):
1410 Add support for Objective C. Fixes Savannah bug #16389.
1411 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1413 * function.c (func_lastword): Initialize p.
1415 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1416 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1417 Dave Korn <dave.korn@artimi.com>
1419 2007-05-08 Paul Smith <psmith@gnu.org>
1421 Fix Savannah bug #19656:
1423 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1425 * make.h: Change all case-insensitive string compares to use
1426 strcasecmp() (from POSIX). If we don't have that but do have one
1427 of the others, define strcasecmp to be one of those instead. If
1428 we don't have any, declare a prototype for our own version.
1430 * misc.c (strcasecmp): Use this if we can't find any native
1431 case-insensitive string comparison function.
1432 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1433 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1435 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1436 strcasecmp() instead of stricmp().
1437 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1438 instead of strcmpi().
1439 * acinclude.m4: Remove the strcasecmp() check from here.
1441 2007-03-21 Paul Smith <psmith@gnu.org>
1443 * configure.in: Don't turn on case-insensitive file system support
1444 if --disable-... is given. Fixes Savannah bug #19348.
1446 2007-03-19 Paul Smith <psmith@gnu.org>
1448 * ALL: Use the strcache for all file name strings, or other
1449 strings which we will never free. The goal is to save memory by
1450 avoiding duplicate copies of strings. However, at the moment this
1451 doesn't save much memory in most situations: due to secondary
1452 expansion we actually save prerequisite lists twice (once before
1453 the secondary expansion, and then again after it's been parsed
1454 into individual file names in the dep list). We will resolve this
1455 in a future change, by doing the parsing up-front for targets
1456 where secondary expansion is not set.
1458 Moving things into the strcache also allows us to use const
1459 pointers in many more places.
1461 2007-01-03 Paul Smith <psmith@gnu.org>
1463 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1464 the function, not just the first. Fixes Savannah bug #18680.
1466 2006-11-18 Paul Smith <psmith@gnu.org>
1468 * strcache.c (strcache_add_len): Don't allocate a new buffer
1469 unless the string is not already nil-terminated. Technically this
1470 is a violation of the standard, since we may be passed an array
1471 that is not long enough to test one past. However, in make this
1472 is never true since we only use nil-terminated strings or
1473 sub-strings thereof.
1475 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1477 * main.c: New global cmd_prefix, defaults to '\t'.
1478 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1481 * dir.c: Constified.
1482 (dir_contents_file_exists_p): Check for an error return from
1483 readdir(), just in case.
1485 * commands.c: Constified.
1486 * default.c: Constified.
1487 * expand.c: Constified.
1488 * function.c: Partial constification.
1489 * variable.c: Partial constification.
1490 * vmsify.c: Constification. Hard to test this but I hope I didn't
1492 * vpath.c: Partial constification.
1493 * w32/pathstuff.c: Partial constification.
1495 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1497 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1498 backslashes and drive letters as absolute.
1500 2006-10-22 Paul Smith <psmith@gnu.org>
1502 * main.c (struct command_switch): Use const and void*.
1504 2006-10-21 Paul Smith <psmith@gnu.org>
1507 * arscan.c: Constified.
1509 2006-09-30 Paul Smith <psmith@gnu.org>
1511 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1512 point to lastword since the example was updated.
1513 Fixes Savannah bug #16304.
1514 (Secondary Expansion): Correct example description.
1515 Fixes Savannah bug #16468.
1516 (Makefile Contents): Clarify that comments cannot appear within
1517 variable references or function calls.
1518 Fixes Savannah bug #16577.
1519 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1520 Fixes Savannah bug #17701.
1521 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1523 prerequisites. Fixes Savannah bug #17880.
1524 (Rule Syntax): "lise" -> "list"
1525 (Multiple Rules): ... -> @dots{}
1526 (Splitting Lines): ditto.
1528 * remake.c (update_file_1): Prereqs that don't exist should be
1529 considered changed, for the purposes of $?.
1530 Fixes Savannah bug #16051.
1532 * make.1: Remove extraneous "+".
1533 Fixes Savannah bug #16652.
1535 2006-09-06 Paul D. Smith <psmith@gnu.org>
1537 * configure.in: Include sys/types.h when checking for sys/wait.h.
1539 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1541 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1544 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1545 Normally, it is defined in config.h.
1547 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1550 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1551 sh_chars_sh for Windows platforms that emulate Unix.
1553 2006-05-07 Paul D. Smith <psmith@gnu.org>
1555 * README.OS2.template: Updates provided by Andreas Buening
1556 <andreas.buening@nexgo.de>.
1558 2006-04-30 Paul D. Smith <psmith@gnu.org>
1560 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1561 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1563 2006-04-26 Paul D. Smith <psmith@gnu.org>
1565 * README.cvs: Add a reminder to notify the GNU translation robot.
1567 * doc/make.texi: Change @direcategory (requested by Karl Berry).
1569 2006-04-20 Paul D. Smith <psmith@gnu.org>

1572 that don't have extended grep.
1573 (cvsclean): Use $(PERL) instead of perl.
1575 2006-04-09 Paul D. Smith <psmith@gnu.org>
1577 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1579 * expand.c, implicit.c, main.c, read.c: Rename variables so that

1621 Version 3.81 released.
1623 * NEWS: Updated for 3.81.
1625 * README.cvs: Mention that vpath builds are not supported out of
1626 CVS. Fixes Savannah bug #16236.

1630 2006-03-26 Paul D. Smith <psmith@gnu.org>
1632 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1633 support from automake, as described in the Texinfo manual.
1635 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1637 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b

1641 Declare and define sh_chars_sh[].
1643 2006-03-23 Paul D. Smith <psmith@gnu.org>
1645 * configure.in: Look for build.sh.in in $srcdir so it will be
1646 built for remote configurations as well.
1648 * Makefile.am: Make sure to clean up build.sh during distclean.
1649 Fixes Savannah bug #16166.
1651 * misc.c (log_access): Takes a const char *.
1652 * function.c (fold_newlines): Takes an unsigned int *.
1653 Both fixes for Savannah bug #16170.
1655 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1657 * implicit.c (pattern_search): Call set_file_variables only
1658 if we have prerequisites that need second expansion. Fixes
1659 Savannah bug #16140.
1661 2006-03-19 Paul D. Smith <psmith@gnu.org>
1663 * remake.c (update_file): Add alloca(0) to clean up alloca'd

1676 2006-03-17 Paul D. Smith <psmith@gnu.org>
1678 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1679 allow multiple concurrent runs.
1680 Patch from Joseph Myers <joseph@codesourcery.com>
1682 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1684 * dep.h (struct dep): Add the stem field.
1685 * misc.c (alloc_dep, free_dep): New functions.
1686 (copy_dep_chain): Copy stem.
1687 (free_dep_chain): Use free_dep.
1688 * read.c (record_files): Store stem in the dependency line.
1689 * file.c (expand_deps): Use stem stored in the dependency line. Use
1690 free_dep_chain instead of free_ns_chain.
1691 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1692 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1693 * main.c (main, handle_non_switch_argument): Ditto.
1694 * remake.c (check_dep): Ditto.

1700 expanding the result, we expand (or not, if it's simple) each part
1702 (allocated_variable_append): Don't expand the final result.
1703 Fixes Savannah bug #15913.
1705 2006-03-09 Paul Smith <psmith@gnu.org>
1707 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1708 listed non-existent files as changed. Turns out there's a bug in
1709 the Linux kernel builds which means that this change causes
1710 everything to rebuild every time. We will re-introduce this fix
1711 in the next release, to give them time to fix their build system.
1712 Fixes Savannah bug #16002.
1713 Introduces Savannah bug #16051.
1715 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1727 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1728 to be null; don't core in that case.
1730 2006-02-19 Paul D. Smith <psmith@gnu.org>
1732 * commands.c (set_file_variables): Realloc, not malloc, the static
1733 string values to avoid memory leaks.
1735 * expand.c (recursively_expand_for_file): Only set reading_file to
1736 an initialized value.
1738 * implicit.c (pattern_search): We need to make a copy of the stem
1739 if we get it from an intermediate dep, since those get freed.
1741 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1743 (enter_file) [VMS]: Ditto.
1744 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1750 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1751 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1752 the calls to _beginthreadex.
1754 * expand.c (recursively_expand_for_file): Initialize `save' to
1755 prevent compiler warnings.
1757 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1759 * job.c (construct_command_argv_internal): Don't create a temporary
1760 script/batch file if we are under -n. Call _setmode to switch the
1761 script file stream to text mode.
1763 2006-02-17 Paul D. Smith <psmith@gnu.org>
1765 * variable.c (merge_variable_set_lists): Don't try to merge the
1766 global_setlist. Not only is this useless, but it can lead to
1767 circularities in the linked list, if global_setlist->next in one
1768 list gets set to point to another list which also ends in
1770 Fixes Savannah bug #15757.
1772 2006-02-15 Paul D. Smith <psmith@gnu.org>
1774 Fix for Savannah bug #106.
1776 * expand.c (expanding_var): Keep track of which variable we're
1777 expanding. If no variable is being expanded, it's the same as
1779 * make.h (expanding_var): Declare it.
1780 * expand.c (recursively_expand_for_file): Set expanding_var to the
1781 current variable we're expanding, unless there's no file info in
1782 it (could happen if it comes from the command line or a default
1783 variable). Restore it before we exit.
1784 * expand.c (variable_expand_string): Use the expanding_var file
1785 info instead of the reading_file info.
1786 * function.c (check_numeric): Ditto.

1791 (handle_function): Ditto.
1793 2006-02-14 Paul D. Smith <psmith@gnu.org>
1795 * read.c (eval): Even if the included filenames expands to the
1796 empty string we still need to free the allocated buffer.
1798 * implicit.c (pattern_search): If we allocated a variable set for
1799 an impossible file, free it.
1800 * variable.c (free_variable_set): New function.
1801 * variable.h: Declare it.
1803 * read.c (read_all_makefiles): Makefile names are kept in the
1804 strcache, so there's never any need to alloc/free them.
1807 * main.c (main): Add "archives" to the .FEATURES variable if
1808 archive support is enabled.
1809 * doc/make.texi (Special Variables): Document it.
1811 2006-02-13 Paul D. Smith <psmith@gnu.org>
1813 * implicit.c (pattern_search): Add checking for DOS pathnames to
1814 the pattern rule target LASTSLASH manipulation.

1819 * (ALL FILES): Updated copyright and license notices.
1821 2006-02-10 Paul D. Smith <psmith@gnu.org>
1823 A new internal capability: the string cache is a read-only cache
1824 of strings, with a hash table interface for fast lookup. Nothing
1825 in the cache will ever be freed, so there's no need for reference
1826 counting, etc. This is the beginning of a full solution for
1827 Savannah bug #15182, but for now we only store makefile names here.
1829 * strcache.c: New file. Implement a read-only string cache.
1830 * make.h: Add prototypes for new functions.
1831 * main.c (initialize_global_hash_tables): Initialize the string cache.
1832 (print_data_base): Print string cache stats.
1833 * read.c (eval_makefile): Use the string cache to store makefile
1834 names. Rewrite the string allocation to be sure we free everything.
1836 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1838 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1839 directory time stamp didn't change, except on FAT filesystems.
1840 Suggested by J. David Bryan <jdbryan@acm.org>.
1842 2006-02-09 Paul D. Smith <psmith@gnu.org>
1844 * function.c (func_or): Implement a short-circuiting OR function.
1845 (func_and): Implement a short-circuiting AND function.
1846 (function_table_init): Update the table with the new functions.
1847 * doc/make.texi (Conditional Functions): Changed the "if" section
1848 to one on general conditional functions. Added documentation for
1849 $(and ...) and $(or ...) functions.
1850 * NEWS: Note new $(and ...) and $(or ...) functions.

1861 * vpath.c (selective_vpath_search): If the file we find has a
1862 timestamp from -o or -W, use that instead of the real time.
1863 * remake.c (f_mtime): If the mtime is a special token from -o or
1864 -W, don't overwrite it with the real mtime.
1865 Fixes Savannah bug #15341.
1867 Updates from Markus Mauhart <qwe123@chello.at>:
1869 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1870 (process_signal, process_last_err, process_exit_code): Manage
1871 invalid handle values.
1872 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1873 manage invalid handles; remove them.

1875 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1882 Fixes Savannah bug #15533.
1883 * filedef.h (struct file): Add a new LAST pointer.
1885 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1886 the comparison. For 64-bits systems the result of the subtraction
1887 might not fit into an int. Use comparison instead.
1888 Fixes Savannah bug #15534.
1890 * doc/make.texi: Update the chapter on writing commands to reflect
1891 the changes made in 3.81 for backslash/newline and SHELL handling.

1911 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1913 * remake.c (update_goal_chain): Set g->changed instead of
1914 incrementing it, as it is only 8-bit wide, and could overflow if
1915 many commands got started in update_file.
1917 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1919 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1937 the shell is not sh.exe.
1939 * job.c (create_batch_file): Renamed from create_batch_filename;
1940 all callers changed. Don't close the temporary file; return its
1941 file descriptor instead. New arg FD allows to return the file
1943 (construct_command_argv_internal): Use _fdopen instead of fopen to
1944 open the batch file.
1946 2006-01-04 Paul D. Smith <psmith@gnu.org>

1976 handling of backslash-newline sequences. Mention the differences
1977 on MS-DOS and MS-Windows.
1979 * NEWS: More details about building the MinGW port and a pointer
1980 to README.W32. Fix the section name that describes the new
1981 backward-incompatible processing of backslash-newline sequences.
1982 The special processing of SHELL set to "cmd" is only relevant to
1983 MS-Windows, not MS-DOS.
1985 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1987 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1988 to DWORD, to avoid compiler warnings.

2013 2005-12-11 Paul D. Smith <psmith@gnu.org>
2015 * implicit.c (pattern_search): If 2nd expansion is not set for
2016 this implicit rule, replace the pattern with the stem directly,
2017 and don't re-expand the variable list. Along with the other

2082 2005-10-16 Paul D. Smith <psmith@gnu.org>
2084 * main.c (main): Set CURDIR to be a file variable instead of a
2085 default, so that values of CURDIR inherited from the environment
2086 won't override the make value.
2088 2005-09-26 Paul D. Smith <psmith@gnu.org>
2090 * job.c (construct_command_argv_internal): If the line is empty
2091 remember to free the temporary argv strings.
2094 2005-09-16 Paul D. Smith <psmith@gnu.org>
2096 * job.c (start_job_command): The noerror flag is a boolean (single
2097 bit); set it appropriately.
2098 Reported by Mark Eichin <eichin@metacarta.com>
2100 2005-08-29 Paul D. Smith <psmith@gnu.org>
2102 * function.c (func_error): On Windows, output from $(info ...)
2103 seems to come in the wrong order. Try to force it with fflush().
2105 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2107 * read.c (record_files): Move code that sets stem for static
2108 pattern rules out of the if (!two_colon) condition so it is
2109 also executed for two-colon rules. Fixes Savannah bug #13881.
2111 2005-08-08 Paul D. Smith <psmith@gnu.org>
2113 * make.h: Don't test that __STDC__ is non-0. Some compilers
2114 (Windows for example) set it to 0 to denote "ISO C + extensions".
2117 2005-08-07 Paul D. Smith <psmith@gnu.org>
2119 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2120 conditional (slightly different version of a fix from Eli).
2122 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2123 If make is running in parallel without -k and two jobs die in a
2124 row, but not too close to each other, then make will quit without
2125 waiting for the rest of the jobs to die.
2127 * main.c (die): Don't reset err before calling reap_children() the
2128 second time: we still want it to be in the error condition.
2129 * job.c (reap_children): Use a static variable, rather than err,
2130 to control whether or not the error message should be printed.
2132 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2134 * w32/subproc/sub_proc.c: Include signal.h.
2135 (process_pipe_io, process_file_io): Pass a pointer to a local
2136 DWORD variable to GetExitCodeProcess. If the exit code is
2137 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2139 * job.c [WINDOWS32]: Include windows.h.
2140 (main_thread) [WINDOWS32]: New global variable.
2141 (reap_children) [WINDOWS32]: Get the handle for the main thread
2142 and store it in main_thread.
2144 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2145 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2146 doing anything else. When we are done, close the main thread
2147 handle and exit with status 130.
2149 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2151 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2154 * main.c (find_and_set_default_shell): If found a DOSish shell,
2155 set sh_found and the value of default_shell, and report the
2156 findings in debug mode.
2158 * job.c (construct_command_argv_internal): Check unixy_shell, not
2159 no_default_sh_exe, to decide whether to use Unixy or DOSish
2162 * README.W32: Update with info about the MinGW build.
2164 * build_w32.bat: Support MinGW.
2166 * w32/subproc/build.bat: Likewise.
2168 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2169 printing DWORD args.
2171 * function.c (windows32_openpipe): Fix format strings for printing
2174 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2176 (start_job_command): Fix format string for printing the result of
2178 (start_job_command) [WINDOWS32]: Do not define.
2179 (exec_command): Fix format string for printing HANDLE args.
2181 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2182 to avoid compiler warnings.
2183 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2184 (Note: some of these fixes were submitted independently by J. Grant)
2186 2005-07-30 J. Grant <jg@jguk.org>
2188 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2189 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2190 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2192 2005-07-15 Paul Smith <psmith@gnu.org>
2194 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2195 we don't have a POSIX shell, then revert to the old
2196 backslash-newline behavior (where they are stripped).
2199 2005-07-08 Paul D. Smith <psmith@gnu.org>
2201 * config.h.W32.template: Reorder to match the standard config.h,
2202 for easier comparisons.
2203 From J. Grant <jg@jguk.org>
2205 * maintMakefile: Remove .dep_segment before overwriting it, in
2206 case it's not writable or noclobber is set.
2207 * expand.c (variable_expand_string): Cast result of pointer
2208 arithmetic to avoid a warning.
2209 * main.c (switches): Add full-fledged final initializer.
2211 2005-07-06 Paul D. Smith <psmith@gnu.org>
2213 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2214 * signame.c (strsignal): If we found _sys_siglist[] or
2215 __sys_siglist[] use those instead of sys_siglist[].
2216 From Albert Chin <china@thewrittenword.com>
2218 2005-07-04 Paul D. Smith <psmith@gnu.org>
2220 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2221 globfree(); set up to use the GNU versions.
2222 From Martin Zinser <zinser@zinser.no-ip.info>
2224 2005-07-03 Paul D. Smith <psmith@gnu.org>
2226 From J. Grant <jg@jguk.org>:
2228 * README.W32.template: Update the Windows and tested MSVC versions.
2229 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2230 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2231 * build_w32.bat: Ditto.
2232 * w32/subproc/build.bat: Ditto.
2234 2005-06-28 Paul D. Smith <psmith@gnu.org>
2236 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2237 declaration was checked but not present.
2239 2005-06-27 Paul D. Smith <psmith@gnu.org>
2241 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2242 to unsigned long. Fixes Savannah bug #13550.
2244 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2245 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2246 Fixes Savannah bug #13551.
2248 2005-06-26 Paul D. Smith <psmith@gnu.org>
2250 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2251 it if ANSI_STRING is not set.
2253 2005-06-25 Paul D. Smith <psmith@gnu.org>
2255 * read.c (eval): If no filenames are passed to any of the
2256 "include" variants, don't print an error.
2257 * doc/make.texi (Include): Document this.
2258 Fixes Savannah bug #1761.
2260 * job.c (construct_command_argv_internal): Sanitize handling of
2261 backslash/newline pairs according to POSIX: that is, keep the
2262 backslash-newline in the command script, but remove a following
2263 TAB character, if present. In the fast path, make sure that the
2264 behavior matches what the shell would do both inside and outside
2265 of quotes. In the slow path, quote the backslash and put a
2266 literal newline in the string.
2267 Fixes Savannah bug #1332.
2268 * doc/make.texi (Execution): Document the new behavior and give
2270 * NEWS: Make a note of the new behavior.
2272 * make.h [WINDOWS32]: #include <direct.h>.
2273 Fixes Savannah bug #13478.
2275 * remake.c (name_mtime): If the stat() of a file fails and the -L
2276 option was given and the file is a symlink, take the best mtime of
2277 the symlink we can get as the mtime of the file and don't fail.
2278 Fixes Savannah bug #13280.
2280 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2281 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2282 inside a variable reference. Make this function static as it's
2284 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2285 parsing an unexpanded line looking for semicolons.
2286 Fixes Savannah bug #1454.
2287 * misc.c (remove_comments): Move this to read.c and make it static
2288 as it's only used there. Call find_char_unquote() with new arg.
2289 * make.h: Remove prototypes for find_char_unquote() and
2290 remove_comments() since they're static now.
2292 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2293 its export flag and obtain its value. When we need to re-exec,
2294 increment the value and add it into the environment.
2295 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2296 * NEWS: Mention MAKE_RESTARTS.
2297 * main.c (always_make_set): New variable. Change the -B option to
2298 set this one instead.
2299 (main): When checking makefiles, only set always_make_flag if
2300 always_make_set is set AND the restarts flag is 0. When building
2301 normal targets, set it IFF always_make_set is set.
2302 (main): Avoid infinite recursion with -W, too: only set what-if
2303 files to NEW before we check makefiles if we've never restarted
2304 before. If we have restarted, set what-if files to NEW _after_ we
2306 Fixes Savannah bug #7566:
2308 2005-06-17 Paul D. Smith <psmith@gnu.org>
2310 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2311 in the prerequisites list.
2313 2005-06-12 Paul D. Smith <psmith@gnu.org>
2315 Fix Savannah bug # 1328.
2317 * configure.in: Check for atexit().
2318 * misc.c (close_stdout): Test stdout to see if writes to it have
2319 failed. If so, be sure to exit with a non-0 error code. Based on
2320 code found in gnulib.
2321 * make.h: Prototype.
2322 * main.c (main): Install close_stdout() with atexit().
2324 2005-06-10 Paul D. Smith <psmith@gnu.org>
2326 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2328 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2329 headers; make vmsWaitForChildren() static; extern vmsify().
2330 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2331 Don't create child_execute_job() here (it's in vmsjobs.c).
2332 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2334 2005-06-09 Paul D. Smith <psmith@gnu.org>
2336 * variable.c (push_new_variable_scope): File variables point
2337 directly to the global_setlist variable. So, inserting a new
2338 scope in front of that has no effect on those variables: they
2339 don't go through current_variable_set_list. If we're pushing a
2340 scope and the current scope is global, push it "the other way" so
2341 that the new setlist is in the global_setlist variable, and
2342 next points to a new setlist with the global variable set.
2343 (pop_variable_scope): Properly undo a push with the new
2345 Fixes Savannah bug #11913.
2347 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2349 * job.c (reap_children): Don't die of the command failed but
2350 the dontcare flag is set. Fixes Savannah bug #13216.
2352 * implicit.c (pattern_search): When creating a target from
2353 an implicit rule match, lookup pattern target and set precious
2354 flag in a newly created target. Fixes Savannah bug #13218.
2356 2005-05-13 Paul D. Smith <psmith@gnu.org>
2358 Implement "if... else if... endif" syntax.
2360 * read.c (eval): Push all checks for conditional words ("ifeq",
2361 "else", etc.) down into the conditional_line() function.
2362 (conditional_line): Rework to allow "else if..." clause. New
2363 return value -2 for lines which are not conditionals. The
2364 ignoring flag can now also be 2, which means "already parsed a
2365 true branch". If that value is seen no other branch of this
2366 conditional can be considered true. In the else parsing if there
2367 is extra text after the else, invoke conditional_line()
2368 recursively to see if it's another conditional. If not, it's an
2369 error. If so, raise the conditional value to this level instead
2370 of creating a new conditional nesting level. Special check for
2371 "else" and "endif", which aren't allowed on the "else" line.
2372 * doc/make.texi (Conditional Syntax): Document the new syntax.
2374 2005-05-09 Paul D. Smith <psmith@gnu.org>
2376 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2377 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2378 recurses to the w32 directory, even on non-Windows systems. Use
2379 the method suggested in the automake manual.
2380 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2381 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2383 2005-05-07 Paul D. Smith <psmith@gnu.org>
2385 * main.c (die): If we're dying with a fatal error (not that a
2386 command has failed), write back any leftover tokens before we go.
2388 * job.c (set_child_handler_action_flags): If there are jobs
2389 waiting for the load to go down, set an alarm to go off in 1
2390 second. This allows us to wake up from a potentially long-lasting
2391 read() and start a new job if the load has gone down. Turn it off
2393 (job_noop): Dummy signal handler function.
2394 (new_job): Invoke it with the new semantics.
2396 * docs/make.texi: Document secondary expansion. Various cleanups
2399 2005-05-03 Paul D. Smith <psmith@gnu.org>
2401 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2402 the targets which are to ultimately be made are called "goals";
2403 see the GNU make manual. Also, MAKECMDGOALS, etc.
2405 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2406 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2407 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2409 2005-05-02 Paul D. Smith <psmith@gnu.org>
2411 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2412 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2413 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2414 functions to vmsjobs.c. #include it into jobs.c.
2416 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2417 jobserver tokens. I found that this happens when an exported
2418 recursive variable contains a $(shell ...) function reference: in
2419 this situation we could "forget" to write back a token.
2421 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2422 we have. It's not reliable to depend on the number of children in
2423 our linked list so keep a separate count.
2424 (new_job): Check jobserver_tokens rather than children &&
2425 waiting_jobs. Increment jobserver_tokens when we get one.
2426 (free_child): If jobserver_tokens is 0, internal error. If it's
2427 >1, write a token back to the jobserver pipe (we don't write a
2428 token for the "free" job). Decrement jobserver_tokens.
2430 * main.c: Add variable master_job_slots.
2431 (main): Set it to hold the number of jobs requested if we're the
2432 master process, when using the jobserver.
2433 (die): Sanity checks: first test jobserver_tokens to make sure
2434 this process isn't holding any tokens we didn't write back.
2435 Second, if master_job_slots is set count the tokens left in the
2436 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2438 2005-04-24 Paul D. Smith <psmith@gnu.org>
2440 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2441 with -l# can lose jobserver tokens, because waiting jobs are not
2442 consulted properly when checking for the "free" token.
2444 * job.c (free_child): Count waiting_jobs as having tokens.
2445 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2446 handle jobs waiting for the load to drop.
2448 2005-04-23 Paul D. Smith <psmith@gnu.org>
2450 * main.c (main): Be careful to not core if a variable setting in
2451 the environment doesn't contain an '='. This is illegal but can
2452 happen in broken setups.
2453 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2455 2005-04-12 Paul D. Smith <psmith@gnu.org>
2457 The second expansion feature causes significant slowdown. Timing
2458 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2459 read the makefile before the feature, to 11+s to do the same
2460 operations after the feature. Additionally, memory usage
2461 increased drastically. To fix this I added some intelligence that
2462 avoids the overhead of the second expansion unless it's required.
2464 * dep.h: Add a new boolean field, need_2nd_expansion.
2466 * read.c (eval): When creating the struct dep for the target,
2467 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2468 (record_files): If there's a "%" in a static pattern rule, it gets
2469 converted to "$*" so set need_2nd_expansion to 1.
2471 * file.c (expand_deps): Rework to be more efficient. Only perform
2472 initialize_file_variables(), set_file_variables(), and
2473 variable_expand_for_file() if the need_2nd_expansion is set.
2475 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2476 (pattern_search): Ditto.
2477 * main.c (handle_non_switch_argument): Ditto.
2479 * read.c (read_all_makefiles): Ditto.
2480 (eval_makefile): Ditto.
2482 2005-04-07 Paul D. Smith <psmith@gnu.org>
2484 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2485 * variable.c (sync_Path_environment): Ditto.
2486 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2488 * main.c (main): Define the .FEATURES variable.
2489 * NEWS: Announce .FEATURES.
2490 * doc/make.texi (Special Variables): Document .FEATURES.
2492 * remake.c (check_dep): If a file is .PHONY, update it even if
2493 it's marked intermediate. Fixes Savannah bug #12331.
2495 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2497 * file.c (expand_deps): Factor out the second expansion and
2498 prerequisite line parsing logic from snap_deps().
2500 * file.c (snap_deps): Use expand_deps(). Expand and parse
2501 prerequisites of the .SUFFIXES special target first. Fixes
2502 Savannah bug #12320.
2504 2005-03-13 Paul D. Smith <psmith@gnu.org>
2506 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2509 2005-03-11 Paul D. Smith <psmith@gnu.org>
2511 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2512 available, not undefined (from Earnie Boyd).
2514 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2516 * implicit.c (pattern_search): Mark an intermediate target as
2517 precious if it happened to be a prerequisite of some (other)
2518 target. Fixes Savannah bug #12267.
2520 2005-03-09 Paul D. Smith <psmith@gnu.org>
2522 * read.c (eval_makefile): Add alloca(0).
2523 (eval_buffer): Ditto.
2525 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2527 * main.c (main): Use o_file instead of o_default when defining
2528 the .DEFAULT_TARGET special variable.
2529 * read.c (eval): Use define_variable_global() instead of
2530 define_variable() when setting new value for the .DEFAULT_TARGET
2531 special variable. Fixes Savannah bug #12266.
2533 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2535 * imlicit.c (pattern_search): Mark files for which an implicit
2536 rule has been found as targets. Fixes Savannah bug #12202.
2538 2005-03-04 Paul D. Smith <psmith@gnu.org>
2541 * doc/make.texi (Automatic Variables): Document $|.
2543 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2545 * read.c (record_files): Instead of substituting % with
2546 actual stem value in dependency list replace it with $*.
2547 This fixes stem triple expansion bug.
2549 * implicit.c (pattern_search): Copy stem to a separate
2550 buffer and make it a properly terminated string. Assign
2551 this buffer instead of STEM (which is not terminated) to
2552 f->stem. Instead of substituting % with actual stem value
2553 in dependency list replace it with $*. This fixes stem
2554 triple expansion bug.
2556 2005-03-01 Paul D. Smith <psmith@gnu.org>
2558 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2559 on Windows, as it takes a handle not a pid. Just exit.
2560 Fix from patch #3679, provided by Alessandro Vesely.
2562 * configure.in: Update check for sys_siglist[] from autoconf manual.
2563 * signame.c (strsignal): Update to use the new autoconf macro.
2565 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2567 * read.c (record_files): Add a check for the list of prerequisites
2568 of a static pattern rule being empty. Fixes Savannah bug #12180.
2570 2005-02-28 Paul D. Smith <psmith@gnu.org>
2572 * doc/make.texi (Text Functions): Update docs to allow the end
2573 ordinal for $(wordlist ...) to be 0.
2574 * function.c (func_wordlist): Fail if the start ordinal for
2575 $(wordlist ...) is <1. Matches documentation.
2576 Resolves Savannah support request #103195.
2578 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2579 previously we were stopping when !-q, exactly the opposite. This
2580 has been wrong since version 1.34, in 1994!
2581 (update_file): If we got an error don't break out to run more
2582 double-colon rules: just return immediately.
2583 Fixes Savannah bug #7144.
2585 2005-02-27 Paul D. Smith <psmith@gnu.org>
2587 * misc.c (end_of_token): Make argument const.
2588 * make.h: Update prototype.
2590 * function.c (abspath, func_realpath, func_abspath): Use
2591 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2592 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2593 * read.c (record_files): Ditto.
2594 * variable.c (do_variable_definition): Ditto.
2596 * function.c (func_error): Create a new function $(info ...) that
2597 simply prints the message to stdout with no extras.
2598 (function_table_init): Add new function to the table.
2599 * NEWS: Add $(info ...) reference.
2600 * doc/make.texi (Make Control Functions): Document it.
2602 New feature: if the system supports symbolic links, and the user
2603 provides the -L/--check-symlink-time flag, then use the latest
2604 mtime between the symlink(s) and the target file.
2606 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2607 readlink(). If both are available, define MAKE_SYMLINKS.
2608 * main.c: New variable: check_symlink_flag.
2609 (usage): Add a line for -L/--check-symlink-times to the help string.
2610 (switches): Add -L/--check-symlink-times command line argument.
2611 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2612 print a warning and disable it again.
2613 * make.h: Declare check_symlink_flag.
2614 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2615 if the file is a symlink then check each link in the chain and
2616 choose the NEWEST mtime we find as the mtime for the file. The
2617 newest mtime might be the file itself!
2618 * NEWS: Add information about this new feature.
2619 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2621 Avoid core dumps described in Savannah bug # 12124:
2623 * file.c: New variable snapped_deps remember whether we've run
2625 (snap_deps): Set it.
2626 * filedef.h: Extern it.
2627 * read.c (record_files): Check snapped_deps; if it's set then
2628 we're trying to eval a new target/prerequisite relationship from
2629 within a command script, which we don't support. Fatal.
2631 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2633 Implementation of the .DEFAULT_TARGET special variable.
2635 * read.c (eval): If necessary, update default_target_name when
2637 * read.c (record_files): Update default_target_file if
2638 default_target_name has changed.
2639 * main.c (default_target_name): Define.
2640 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2641 default_target_name is set use default_target_file as a root
2643 * filedef.h (default_target_name): Declare.
2644 * dep.h (free_dep_chain):
2645 * misc.c (free_dep_chain): Change to operate on struct nameseq
2646 and change name to free_ns_chain.
2647 * file.c (snap_deps): Update to use free_ns_chain.
2649 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2651 Implementation of the second expansion in explicit rules,
2652 static pattern rules and implicit rules.
2654 * read.c (eval): Refrain from chopping up rule's dependencies.
2655 Store them in a struct dep as a single dependency line. Remove
2656 the code that implements SySV-style automatic variables.
2658 * read.c (record_files): Adjust the code that handles static
2659 pattern rules to expand all percents instead of only the first
2660 one. Reverse the order in which dependencies are stored so that
2661 when the second expansion reverses them again they appear in
2662 the makefile order (with some exceptions, see comments in
2663 the code). Remove the code that implements SySV-style automatic
2666 * file.c (snap_deps): Implement the second expansion and chopping
2667 of dependency lines for explicit rules.
2669 * implicit.c (struct idep): Define an auxiliary data type to hold
2670 implicit rule's dependencies after stem substitution and
2673 * implicit.c (free_idep_chain): Implement.
2675 * implicit.c (get_next_word): Implement helper function for
2676 parsing implicit rule's dependency lines into words taking
2677 into account variable expansion requests. Used in the stem
2680 * implicit.c (pattern_search): Implement the second expansion
2681 for implicit rules. Also fixes bug #12091.
2683 * commands.h (set_file_variables): Declare.
2684 * commands.c (set_file_variables): Remove static specifier.
2686 * dep.h (free_dep_chain): Declare.
2687 * misc.c (free_dep_chain): Implement.
2689 * variable.h (variable_expand_for_file): Declare.
2690 * expand.c (variable_expand_for_file): Remove static specifier.
2692 * make.h (strip_whitespace): Declare.
2693 * function.c (strip_whitespace): Remove static specifier.
2695 2005-02-26 Paul D. Smith <psmith@gnu.org>
2697 * main.c (main): Check for ferror() when reading makefiles from stdin.
2698 Apparently some shells in Windows don't close pipes properly and
2701 2005-02-24 Jonathan Grant <jg@jguk.org>
2703 * configure.in: Add MinGW configuration options, and extra w32 code
2705 * Makefile.am: Add MinGW configuration options, and extra w32 code
2707 * main.c: Determine correct program string (after last \ without .exe).
2708 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2710 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2711 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2712 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2713 environment support.
2715 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2717 * function.c (func_shell): When initializing error_prefix, check
2718 that reading file name is not null. This fixes long-standing
2719 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2721 2005-02-09 Paul D. Smith <psmith@gnu.org>
2723 * maintMakefile: Update the CVS download URL to simplify them.
2724 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2725 downloading the .texi files from Savannah now.
2727 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2729 * main.c (handle_non_switch_argument): Only add variables to
2730 command_variables if they're not already there: duplicate settings
2731 waste space and can be confusing to read.
2733 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2734 this header is never included by non-WINDOWS32 code, and it
2735 requires <config.h> to define which isn't always included first.
2737 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2738 testing MINGW32 versions.
2740 * main.c (log_working_directory): flush stdout to be sure the WD
2741 change is printed before any stderr messages show up.
2743 2005-02-01 Paul D. Smith <psmith@gnu.org>
2745 * maintMakefile (po_repo): Update the GNU translation site URL.
2747 2004-12-01 Paul D. Smith <psmith@gnu.org>
2749 * main.c (main): Change char* env_shell to struct variable shell_var.
2750 * variable.c (target_environment): Use new shell_var.
2752 2004-11-30 Paul D. Smith <psmith@gnu.org>
2754 * configure.in: The old way we avoided creating build.sh from
2755 build.sh.in before build.sh.in exists doesn't work anymore; we
2756 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2757 the help!). This also keeps automake from complaining.
2758 * Makefile.am (README): Add a dummy target so automake won't
2759 complain that this file doesn't exist when we checkout from CVS.
2760 * maintMakefile (.dep_segment): Rewrite this rule since newer
2761 versions of automake don't provide DEP_FILES.
2763 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2765 Implementation of `realpath' and `abspath' built-in functions.
2767 * configure.in: Check for realpath.
2768 * function.c (abspath): Return an absolute file name that does
2769 not contain any `.' or `..' components, nor repeated `/'.
2770 * function.c (func_abspath): For each name call abspath.
2771 * function.c (func_realpath): For each name call realpath
2772 from libc or delegate to abspath if realpath is not available.
2773 * doc/make.texi (Functions for File Names): Document new functions.
2774 * doc/make.texi (Quick Reference): Ditto.
2776 2004-11-28 Paul D. Smith <psmith@gnu.org>
2778 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2779 arguments. Fixes bug #10252.
2781 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2783 * main.c (main): Set SHELL to v_noexport by default. Remember the
2784 original environment setting of SHELL in the env_shell variable.
2785 * main.h: Export new env_shell variable.
2786 * variable.c (target_environment): If we find a v_noexport
2787 variable for SHELL, add a SHELL variable with the env_shell value.
2788 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2789 * doc/make.texi (Variables/Recursion): Ditto.
2791 2004-11-28 Paul D. Smith <psmith@gnu.org>
2793 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2794 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2795 Patch by Alessandro Vesely.
2797 2004-11-12 Paul D. Smith <psmith@gnu.org>
2799 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2800 the command line if it's inside a string.
2801 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2803 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2805 * function.c (func_lastword): New function: return last word
2806 from the list of words.
2807 * doc/make.texi: Document $(lastword ). Fix broken links in
2808 Quick Reference section.
2810 2004-10-06 Paul D. Smith <psmith@gnu.org>
2812 Apply patch from Alessandro Vesely, provided with bug # 9748.
2813 Fix use of tmpnam() to work with Borland C.
2815 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2816 construction of a temporary filename, and call new function
2817 create_batch_filename().
2818 (create_batch_filename) [WINDOWS32]: New function to create a
2821 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2823 * read.c (record_target_var): Expand simple pattern-specific
2825 * variable.c (initialize_file_variables): Do not expand simple
2826 pattern-specific variable.
2828 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2830 * remake.c (update_file_1): When rebuilding makefiles inherit
2831 dontcare flag from a target that triggered update.
2833 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2835 * variable.c (initialize_file_variables): Mark pattern-specific
2836 variable as a per-target and copy export status.
2838 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2840 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2842 * implicit.c (pattern_search): When considering an implicit rule's
2843 prerequisite check that it is actually a target rather then
2844 just an entry in the file hashtable.
2846 2004-09-21 Paul D. Smith <psmith@gnu.org>
2848 * read.c (readstring): Fix some logic errors in backslash handling.
2849 (eval): Remove some unnecessary processing in buffer handling.
2850 (record_target_var): Assert that parse_variable_definition() succeeded.
2851 Reported by: Markus Mauhart <qwe123@chello.at>.
2853 * misc.c: Removed the sindex() function. All instances of this
2854 function were trivially replaceable by the standard strstr()
2855 function, and that function will always have better (or certainly
2856 no worse) performance than the very simple-minded algorithm
2857 sindex() used. This can matter with complex makefiles.
2858 * make.h: Remove the prototype for sindex().
2859 * function.c (subst_expand): Convert sindex() call to strstr().
2860 This means we no longer need to track the TLEN value so remove that.
2861 (func_findstring): Convert sindex() to strstr().
2862 * commands.c (chop_commands): Convert sindex() calls to strstr().
2863 Suggested by: Markus Mauhart <qwe123@chello.at>.
2865 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2866 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2867 If SHELL is set to CMD.EXE then assume it's batch-mode and
2868 non-unixy. I wrote the code differently from the patch, though,
2869 to make it safer. This also resolves bug #9174.
2871 2004-09-20 Paul D. Smith <psmith@gnu.org>
2873 * expand.c (variable_expand_string): Modify to invoke
2874 patsubst_expand() instead of subst_expand(); the latter didn't
2875 handle suffix patterns correctly.
2876 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2877 was used only from variable_expand_string() and is no longer used
2879 (func_subst): Ditto, on call to subst_expand().
2880 (patsubst_expand): Require the percent pointers to point to the
2881 character after the %, not to the % itself.
2882 * read.c (record_files): New call criteria for patsubst_expand().
2883 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2884 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2886 2004-09-19 Paul D. Smith <psmith@gnu.org>
2888 * function.c (subst_expand): Fix a check in by_word: look for a
2889 previous blank if we're beyond the beginning of the string, not
2890 the beginning of the word.
2891 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2893 2004-05-16 Paul D. Smith <psmith@gnu.org>
2895 * remake.c (update_goal_chain): Change the argument specifying
2896 whether we're rebuilding makefiles to be a global variable,
2897 REBUILDING_MAKEFILES.
2898 (complain): Extract the code that complains about no rules to make
2899 a target into a separate function.
2900 (update_file_1): If we tried to rebuild a file during the makefile
2901 rebuild phase and it was dontcare, then no message was printed.
2902 If we then try to build the same file during the normal build,
2903 print a message this time.
2904 (remake_file): Don't complain about un-remake-able files when
2905 we're rebuilding makefiles.
2907 2004-05-11 Paul D. Smith <psmith@gnu.org>
2909 * job.c (construct_command_argv_internal): OS/2 patches from
2910 Andreas Buening <andreas.buening@nexgo.de>.
2912 2004-05-10 Paul D. Smith <psmith@gnu.org>
2914 * remake.c (update_file): Don't walk the double-colon chain unless
2915 this is a double-colon rule. Fix suggested by Boris Kolpackov
2916 <boris@kolpackov.net>.
2918 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2919 * readme.vms: New section describing OpenVMS support and issues.
2920 * default.c (default_variables): Add support for IA64.
2921 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2922 without some privilege aborts make with the error
2923 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2924 pressing Ctrl+Y and the input device is no terminal. The change
2925 catches this error and just continues.
2927 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2929 2004-04-25 Paul D. Smith <psmith@gnu.org>
2931 * commands.c (set_file_variables): Set $< properly in the face of
2932 order-only prerequisites.
2933 Patch from Boris Kolpackov <boris@kolpackov.net>
2935 2004-04-21 Bob Byrnes <byrnes@curl.com>
2937 * main.c (main): Notice failures to remake makefiles.
2939 2004-03-28 Paul D. Smith <psmith@gnu.org>
2941 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2943 * job.c: No default shell for RISC OS.
2944 (load_too_high): Hard-code the return to 1.
2945 (construct_command_argv_internal): No sh_chars or sh_cmds.
2946 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2948 2004-03-20 Paul D. Smith <psmith@gnu.org>
2950 * variable.c (do_variable_definition): Don't append from the
2951 global set if a previous non-appending target-specific variable
2952 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2955 * expand.c (reference_variable): Don't give up on variables with
2956 no value that have the target-specific append flag set: they might
2957 have a value after all. Reported by Oliver Schmidt
2958 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2959 <nikulin@dx1cmd.inp.nsk.su>.
2961 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2962 refer to absolute pathnames in directories that don't exist: some
2963 portion of the makefile could create those directories before we
2964 match the pattern. Fixes bugs #775 and #108.
2966 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2968 * main.c (main): Free makefile_mtimes if we have any.
2969 * README.W32.template: Update documentation for the current status
2970 of the MS-Windows port.
2971 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2972 environment variable is sometimes already defined which causes the
2974 * main.c (debug_signal_handler): Only define this function if
2975 SIGUSR1 is available.
2977 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2979 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2980 * README.OS2.template: Documentation updates.
2981 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2982 link line for safety.
2983 * maintMakefile (build.sh.in): Remove an extraneous ")".
2984 * job.c (child_execute_job): Close saved FDs.
2985 * job.c (exec_command) [OS/2]: exec_command(): If the command
2986 can't be exec'ed and if the shell is not Unix-sh, then try again
2987 with argv = { "cmd", "/c", ... }. Normally, this code is never
2988 reached for the cmd shell unless the command really doesn't exist.
2989 (construct_command_argv_internal) [OS/2]: The code for cmd
2990 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2991 The CMD builtin commands are case insensitive so use strcasecmp().
2993 2004-03-19 Paul D. Smith <psmith@gnu.org>
2995 * read.c (do_define): Re-order line counter increment so the count
2996 is accurate (we were losing one line per define). Reported by
2997 Dave Yost <Dave@Yost.com>.
2999 2004-03-06 Paul D. Smith <psmith@gnu.org>
3001 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3003 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3004 * misc.c (message,error,fatal): Ditto.
3005 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3006 * config.h.W32.template: Ditto.
3007 * config.h-vms.template: Ditto.
3008 * config.ami.template: Ditto.
3010 2004-03-04 Paul D. Smith <psmith@gnu.org>
3012 * README.template: Add a note about broken /bin/sh on SunOS
3013 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3015 * misc.c (message, error, fatal): Don't use "..." if we're using
3016 varargs. ansi2knr should handle this but it doesn't work: it
3017 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3018 done. On many systems (SunOS for example) va_dcl is a #define.
3019 So, force the use of the non-"..." version on pre-ANSI compilers.
3021 * maintMakefile (sign-dist): Create some rules to help automate
3022 the new GNU ftp upload method.
3024 2004-02-24 Paul D. Smith <psmith@gnu.org>
3026 * config.h.W32.template: Add HAVE_STDARG_H
3027 * config.h-vms.template: Ditto.
3028 * config.ami.template: Ditto.
3030 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3032 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3033 * build_w32.bat: Remove extra "+".
3035 2004-02-23 Paul D. Smith <psmith@gnu.org>
3037 * make.h: Create an UNUSED macro to mark unused parameters.
3038 * (many): Clean up warnings by applying UNUSED, fixing
3039 signed/unsigned incompatibilities, etc.
3041 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3043 * filedef.h: Name the command_state enumeration.
3044 * file.c (set_command_state): Use the enumeration in the function
3047 * configure.in: Explicitly set SET_MAKE to empty, to disable
3048 MAKE=make even when no make already exists. Fix bug #3823.
3050 2004-02-22 Paul D. Smith <psmith@gnu.org>
3052 * maintMakefile: Perl script to clean up all non-CVS files. Use
3053 it on all the subdirectories for the cvs-clean target.
3055 * main.c (decode_switches): Require non-empty strings for all our
3056 string command-line options. Fixes Debian bug # 164165.
3058 * configure.in: Check for stdarg.h and varargs.h.
3059 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3060 for printing messages.
3061 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3066 A number of patches for OS/2 support from Andreas Buening
3067 <andreas.buening@nexgo.de>:
3069 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3070 disable the SIGCHLD handler.
3071 (reap_children) [OS/2]: Remove special handling of job_rfd.
3072 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3073 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3074 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3075 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3076 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3079 2004-02-21 Paul D. Smith <psmith@gnu.org>
3081 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3082 <mail@kristov.de> reports that if process_begin() fails we don't
3083 handle the error condition correctly in all cases.
3084 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3085 to have a newline on the message.
3087 * job.c (construct_command_argv_internal): Add "test" to UNIX
3088 sh_cmds[]. Fixes Savannah bug # 7606.
3090 2004-02-04 Paul D. Smith <psmith@gnu.org>
3092 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3093 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3094 Hartmut Becker <Hartmut.Becker@hp.com>.
3096 2004-01-21 Paul D. Smith <psmith@gnu.org>
3098 * job.c (load_too_high): Implement an algorithm to control the
3099 "thundering herd" problem when using -l to control job creation
3100 via the load average. The system only recomputes the load once a
3101 second but we can start many jobs in a second. To solve this we
3102 keep track of the number of jobs started in the last second and
3103 apply a weight to try to guess what a correct load would be.
3104 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3105 Also fixes bug #4693.
3106 (reap_children): Decrease the job count for this second.
3107 (start_job_command): Increase the job count for this second.
3109 * read.c (conditional_line): Expand the text after ifn?def before
3110 checking to see if it's a single word. Fixes bug #7257.
3112 2004-01-09 Paul D. Smith <psmith@gnu.org>
3114 * file.c (print_file): Recurse to print all targets in
3115 double-colon rules. Fixes bug #4518, reported (with patch) by
3116 Andrew Chatham <chatham@google.com>.
3118 2004-01-07 Paul D. Smith <psmith@gnu.org>
3120 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3121 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3122 AC_FUNC_SETVBUF_REVERSED.
3124 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3125 (MAKE Variable): Fix Savannah bug #4898.
3127 * job.c (construct_command_argv_internal): Add "!" to the list of
3128 shell escape chars. POSIX sh allows it to appear before a
3129 command, to negate the exit code. Fixes bug #6404.
3131 * implicit.c (pattern_search): When matching an implicit rule,
3132 remember which dependencies have the ignore_mtime flag set.
3133 Original fix provided in Savannah patch #2349, by Benoit
3134 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3136 2003-11-22 Paul D. Smith <psmith@gnu.org>
3138 * README.W32.template (Outputs): Clarification on -j with
3139 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3142 2003-11-02 Paul D. Smith <psmith@gnu.org>
3144 * function.c (func_if): Strip all the trailing whitespace from the
3145 condition, then don't expand it. Fixed bug # 5798.
3147 * expand.c (recursively_expand_for_file): If we're expanding a
3148 variable with no file context, then use the variable's context.
3151 2003-10-21 Paul D. Smith <psmith@gnu.org>
3153 * main.c (log_working_directory): Add newlines to printf()s.
3155 * README.cvs: Add a note to ignore warnings during autoreconf.
3157 * maintMakefile (po_repo): Set a new URL for PO file updates.
3158 (get-config/config.guess get-config/config.sub): Get these files
3159 from the Savannah config project instead of ftp.gnu.org.
3161 2003-10-05 Paul Eggert <eggert@twinsun.com>
3163 * main.c (main): Avoid potential subscript error if environ has
3166 2003-08-22 Paul D. Smith <psmith@gnu.org>
3168 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3169 systems which don't yet implement the C89 standard :-/.
3171 2003-07-18 Paul D. Smith <psmith@gnu.org>
3173 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3174 [WINDOWS32]: Initialize hash.
3176 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3178 * dir.c (read_dirstream): Provide a workaround for broken versions of
3179 the MinGW dirent structure.
3181 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3183 * w32/include/dirent.h: Add __MINGW32__ filter.
3185 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3187 * make.h: Add global declaration of *make_host.
3188 * main.c (print_usage): Remove local declaration of *make_host.
3189 (print_version): Display "This program built for ..." after Copyright
3192 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3194 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3195 execution of "makeinfo --html make.texi".
3197 2003-04-30 Paul D. Smith <psmith@gnu.org>
3199 * build.template: Make some changes to maybe allow this script to
3200 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3202 * README.OS2.template: New file for OS/2 support. Original
3203 contributed by Andreas Buening.
3204 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3207 2003-04-19 Paul D. Smith <psmith@gnu.org>
3209 Fix bug #1405: allow a target to match multiple pattern-specific
3212 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3213 variable.c, where they've always belonged.
3214 * rule.h: Move the prototypes and struct pattern_var as well.
3215 * variable.c (initialize_file_variables): Invoke
3216 lookup_pattern_var() in a loop, until no more matches are found.
3217 If a match is found, create a new variable set for the target's
3218 pattern variables. Then merge the contents of each matching
3219 pattern variable set into the target's pattern variable set.
3220 (lookup_pattern_var): Change this function to be usable
3221 in a loop. It takes a starting position: if NULL, start at the
3222 beginning; if non-NULL, start with the pattern variable after that
3223 position, and return the next matching pattern.
3224 (create_pattern_var): Create a unique instance of
3225 pattern-specific variables for every definition in the makefile.
3226 Don't combine the same pattern together. This allows us to
3227 process the variable handling properly even when the same pattern
3228 is used multiple times.
3229 (parse_variable_definition): New function: break out the parsing
3230 of a variable definition line from try_variable_definition.
3231 (try_variable_definition): Call parse_variable_definition to
3233 (print_variable_data_base): Print out pattern-specific variables.
3234 * variable.h (struct variable): Remember when a variable is
3235 conditional. Also remember its flavor.
3236 (struct pattern_var): Instead of keeping a variable set, we just
3237 keep a single variable for each pattern.
3238 * read.c (record_target_var): Each pattern variable contains only a
3239 single variable, not a set, so create it properly.
3240 * doc/make.texi (Pattern-specific): Document the new behavior.
3242 2003-04-17 Paul D. Smith <psmith@gnu.org>
3244 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3245 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3246 file/directory naming rules for VMS so I can't tell whether this
3249 2003-04-09 Paul D. Smith <psmith@gnu.org>
3251 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3252 DOS-style pathnames: backslash separators and drive specifiers.
3254 2003-03-28 Paul D. Smith <psmith@gnu.org>
3256 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3257 the intermediate flag on all targets. Fixes bug #2515.
3259 2003-03-24 Paul D. Smith <psmith@gnu.org>
3261 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3262 Upgrade to autoconf 2.57 and automake 1.7.3.
3264 * job.c: More OS/2 changes from Andreas Buening.
3266 * file.c (print_file): Fix variable initialization.
3269 * remake.c (notice_finished_file):
3271 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3272 some calls (like readdir()) return NULL in valid situations
3273 without resetting errno. Fixes bug #2846.
3275 2003-02-25 Paul D. Smith <psmith@gnu.org>
3277 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3279 * job.c (_is_unixy_shell) [OS/2]: New function.
3280 Set default shell to /bin/sh.
3281 (reap_children): Close the job_rfd pipe here since we don't use a
3283 (set_child_handler_action_flags): define this to empty on OS/2.
3284 (start_job_command): Close the jobserver pipe and use
3285 child_execute_job() instead of fork/exec.
3286 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3287 rather than exec'ing, then reconfigure stdin/stdout.
3288 (exec_command): Rewrite to use spawn instead of exec. Return the
3291 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3292 in DOS. Handle the TEMP environment variable as in DOS. Don't
3293 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3294 use -j in DOS mode. Use child_execute_job() instead of
3297 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3300 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3301 prototypes that return values.
3303 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3305 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3306 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3308 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3311 2003-02-24 Paul D. Smith <psmith@gnu.org>
3313 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3314 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3315 (child_execute_job) [VMS]: Handle error status properly.
3316 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3318 * function.c (func_shell): Use EINTRLOOP() while reading from the
3319 subshell pipe (Fixes bug #2502).
3320 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3322 * main.c (main): Ditto.
3324 2003-01-30 Paul D. Smith <psmith@gnu.org>
3326 * read.c (eval): eval() was not fully reentrant, because the
3327 collapsed buffer was static. Change it to be an automatic
3328 variable so that eval() can be invoked recursively.
3330 (eval): Apply patch # 1022: fix memory reference error on long
3331 target-specific variable lines.
3332 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3334 * function.c (check_numeric): Combine the is_numeric() function
3335 into this function, since it's only called from one place.
3336 Constify this function. Have it print the incorrect string in the
3337 error message. Fixes bug #2407.
3338 (strip_whitespace): Constify.
3339 (func_if): Constify.
3340 * expand.c (expand_argument): Constify.
3342 2003-01-29 Paul D. Smith <psmith@gnu.org>
3344 Fix bug # 2169, also reported by other people on various systems.
3346 * make.h: Some systems, such as Solaris and PTX, do not fully
3347 implement POSIX-compliant SA_RESTART functionality; important
3348 system calls like stat() and readdir() can still fail with EINTR
3349 even if SA_RESTART has been set on the signal handler. So,
3350 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3351 EINTR for system calls which return -1 or 0 (NULL), respectively,
3353 Also, remove the old atomic_stat()/atomic_readdir() and
3354 HAVE_BROKEN_RESTART handling.
3356 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3358 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3359 * remake.c (touch_file): Ditto.
3361 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3362 * read.c (construct_include_path): Ditto.
3363 * remake.c (name_mtime): Ditto.
3364 * vpath.c (selective_vpath_search): Ditto.
3365 * dir.c (find_directory): Ditto.
3366 (local_stat): Ditto.
3367 (find_directory): Use ENULLLOOP() to wrap opendir().
3368 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3370 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3371 atomic_readdir() handling.
3373 2003-01-22 Paul D. Smith <psmith@gnu.org>
3375 * function.c (func_call): Fix Bug #1744. If we're inside a
3376 recursive invocation of $(call ...), mask any of the outer
3377 invocation's arguments that aren't used by this one, so that this
3378 invocation doesn't "inherit" them accidentally.
3380 2002-12-05 Paul D. Smith <psmith@gnu.org>
3382 * function.c (subst_expand): Valery Khamenia reported a
3383 pathological performance hit when doing substitutions on very
3384 large values with lots of words: turns out we were invoking
3385 strlen() a ridiculous number of times. Instead of having each
3386 call to sindex() call strlen() again, keep track of how much of
3387 the text we've seen and pass the length to sindex().
3389 2002-11-19 Paul D. Smith <psmith@gnu.org>
3391 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3394 2002-11-16 Paul D. Smith <psmith@gnu.org>
3396 * NMakefile.template (OBJS): Add hash.c object file.
3397 * SMakefile.template (srcs): Ditto.
3398 * Makefile.ami (objs): Ditto.
3399 * build_w32.bat: Ditto.
3401 * Makefile.DOS.template: Remove extra dependencies.
3403 2002-10-25 Paul D. Smith <psmith@gnu.org>
3405 * expand.c (install_variable_buffer): New function. Install a new
3406 variable_buffer context and return the previous one.
3407 (restore_variable_buffer): New function. Free the current
3408 variable_buffer context and put a previously saved one back.
3409 * variable.h: Prototypes for {install,restore}_variable_buffer.
3410 * function.c (func_eval): Push a new variable_buffer context
3411 before we eval, then restore the old one when we're done.
3414 * read.c (install_conditionals): New function. Install a new
3415 conditional context and return the previous one.
3416 (restore_conditionals): New function. Free the current
3417 conditional context and put a previously saved one back.
3418 (eval): Use the {install,restore}_conditionals for "include"
3420 (eval_buffer): Use {install,restore}_conditionals to preserve the
3421 present conditional state before we evaluate the buffer.
3424 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3426 (Recursion): Add a variable index entry for CURDIR.
3428 * README.cvs: Update to appropriate versions.
3429 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3430 don't need to copy loadavg.c: automake is smart enough to create
3431 it for me. Still have a bug in automake related to ansi2knr tho.
3433 2002-10-14 Paul D. Smith <psmith@gnu.org>
3435 * remake.c (notice_finished_file): Only touch targets if they have
3436 at least one command (as per POSIX). Resolve Bug #1418.
3438 * *.c: Convert to using ANSI C-style function definitions.
3439 * Makefile.am: Enable the ansi2knr feature of automake.
3440 * configure.in: ditto.
3442 2002-10-13 Paul D. Smith <psmith@gnu.org>
3444 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3445 for automatic variable values like $^, etc. In the case of very
3446 large lists of prerequisites this causes problems. Instead reuse
3447 a static buffer (resizeable) for each variable.
3449 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3450 target-specific variable definitions. Check for it and set an
3452 (record_target_var): Set the export field to v_export if the
3453 "exported" flag is set.
3454 * doc/make.texi (Target-specific): Document the ability to use
3457 * doc/make.texi: Change the name of the section on automatic
3458 variables from "Automatic" to "Automatic Variables". Added text
3459 clarifying the scope of automatic variables.
3461 2002-10-04 Paul D. Smith <psmith@gnu.org>
3463 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3465 (record_files): Ditto.
3467 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3468 the search for the '=' to only within the enclosing parens.
3470 2002-10-03 Paul D. Smith <psmith@gnu.org>
3472 Version 3.80 released.
3474 * dir.c: Change hash functions to use K&R function definition style.
3475 * function.c: Ditto.
3477 * variable.c: Ditto.
3479 Update to automake 1.7.
3481 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3482 (pdf): Remove this target as automake now provides one.
3484 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3486 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3488 * makefile.com: Updates for GNU make 3.80.
3489 * makefile.vms: Ditto.
3491 2002-09-23 Paul D. Smith <psmith@gnu.org>
3493 * read.c (enum make_word_type): Remove w_comment.
3494 (get_next_mword): Don't treat comment characters as special; where
3495 this function is used we will never see a comment (it's stripped
3496 before we get here) and treating comments specially means that
3497 targets like "foo\#bar" aren't handled properly.
3499 2002-09-18 Paul D. Smith <psmith@gnu.org>
3501 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3503 * read.c (eval): Expansion of arguments to export/unexport was
3504 ignoring all arguments after the first one. Change the algorithm
3505 to expand the whole line once, then parse the results.
3507 2002-09-17 Paul D. Smith <psmith@gnu.org>
3509 Fix Bug #940 (plus another bug I found while looking at this):
3511 * read.c (record_target_var): enter_file() will add a new entry if
3512 it's a double-colon target: we don't want to do that in this
3513 situation. Invoke lookup_file() and only enter_file() if it does
3514 not already exist. If the file we get back is a double-colon then
3515 add this variable to the "root" double-colon target.
3517 * variable.c (initialize_file_variables): If this file is a
3518 double-colon target but is not the "root" target, then initialize
3519 the root and make the root's variable list the parent of our
3522 2002-09-13 Paul D. Smith <psmith@gnu.org>
3524 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3526 * hash.c (round_up_2): Get rid of a warning.
3528 2002-09-12 Paul D. Smith <psmith@gnu.org>
3530 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3531 so it doesn't complain about getloadavg.c.
3533 * commands.c (set_file_variables): Make sure we always alloca() at
3534 least 1 character for the value of $? (for '\0').
3536 2002-09-11 Paul D. Smith <psmith@gnu.org>
3538 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3539 macro to use RESULT instead of the incorrect _RESULT_.
3541 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3542 and atomic_readdir(). We need to #include dirent.h to get this to
3544 * misc.c (atomic_readdir): Fix typos.
3546 2002-09-10 Paul D. Smith <psmith@gnu.org>
3548 * read.c (eval): Expand variable lists given to export and
3549 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3550 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3552 * doc/make.texi (Variables/Recursion): Document this.
3553 (Conditional Syntax): And here.
3555 2002-09-09 Paul D. Smith <psmith@gnu.org>
3557 * configure.in: Check for memmove().
3559 2002-09-07 Paul D. Smith <psmith@gnu.org>
3561 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3562 Michael Sterrett <msterret@coat.com> reports that while it has
3563 SA_RESTART, it does not work properly.
3565 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3566 that invokes stat() and loops to do it again if it returns EINTR.
3567 (atomic_readdir): Ditto, with readdir().
3569 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3570 and readdir() to atomic_stat() and atomic_readdir().
3572 2002-09-04 Paul D. Smith <psmith@gnu.org>
3574 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3575 reports that GNU make sometimes doesn't recognize that targets can
3576 be made, when directories can be created as prerequisites. He
3577 reports that changing the order of predicates in the DEP->changed
3578 flag test so that lookup_file() is always performed, solves this
3581 2002-08-08 Paul D. Smith <psmith@gnu.org>
3583 * configure.in: Require a newer version of gettext.
3585 * misc.c (perror_with_name): Translate the format string (for
3586 right-to-left language support).
3587 (pfatal_with_name): Ditto.
3589 * main.c: Create a static array of strings to store the usage
3590 text. This is done to facilitate translations.
3591 (struct command_switch): Remove argdesc and description fields.
3592 (switches): Remove values for obsolete fields.
3593 (print_usage): Print each element of the usage array.
3595 * hash.c: Change function definitions to be K&R style.
3597 2002-08-02 Paul D. Smith <psmith@gnu.org>
3599 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3600 this one because it's too hard to get right. We'll look at it for
3602 * main.c (main): Don't create the .TARGETS variable.
3603 * variable.c (handle_special_var): Don't handle .TARGETS.
3605 2002-08-01 Paul D. Smith <psmith@gnu.org>
3607 * main.c (switches): Add a new option, -B (--always-make). If
3608 specified, make will rebuild all targets that it encounters even
3609 if they don't appear to be out of date.
3610 (always_make_flag): New flag.
3611 * make.h: Extern always_make_flag.
3612 * remake.c (update_file_1): Check always_make_flag; if it's set we
3613 will always rebuild any target we can, even if none of its
3614 prerequisites are newer.
3617 * doc/make.texi (Shell Function): Make it clear that make
3618 variables marked as "export" are not passed to instances of the
3621 Add new introspection variable .VARIABLES and .TARGETS.
3623 * variable.c (handle_special_var): New function. If the variable
3624 reference passed in is "special" (.VARIABLES or .TARGETS),
3625 calculate the new value if necessary. .VARIABLES is handled here:

3634 * doc/make.texi (Special Variables): Document them.
3635 * NEWS: Mention them.
3637 * variable.h (struct variable): Add a new flag "exportable" which
3638 is true if the variable name is valid for export.
3639 * variable.c (define_variable_in_set): Set "exportable" when a new
3640 variable is defined.
3641 (target_environment): Use the "exportable" flag instead of
3642 re-checking the name here... an efficiency improvement.
3644 2002-07-31 Paul D. Smith <psmith@gnu.org>
3646 * config.h-vms.template: Updates to build on VMS. Thanks to
3647 Brian_Benning@aksteel.com for helping verify the build.
3648 * makefile.com: Build the new hash.c file.
3649 * hash.h: Use strcpmi(), not stricmp(), in the
3650 HAVE_CASE_INSENSITIVE_FS case.
3652 2002-07-30 Paul D. Smith <psmith@gnu.org>
3654 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing

3660 * variable.c (pop_variable_scope): Remove variable made unused by
3661 new hash infrastructure.
3662 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3663 comparisons as well as name comparisons.
3664 * variable.h: Add a prototype for new hash_init_function_table().
3665 * file.c (lookup_file): Remove variables made unused by new hash
3667 * dir.c (directory_contents_hash_2): Missing return of hash value.
3668 (dir_contents_file_exists_p): Remove variables made unused by new
3669 hash infrastructure.
3672 Installed Greg McGary's integration of the hash functions from the
3673 GNU id-utils package:
3675 2002-07-10 Greg McGary <greg@mcgary.org>
3677 * scripts/functions/filter-out: Add literals to to the
3678 pattern space in order to add complexity, and trigger
3679 use of an internal hash table. Fix documentation strings.
3680 * scripts/targets/INTERMEDIATE: Reverse order of files
3681 passed to expected `rm' command.
3683 2002-07-10 Greg McGary <greg@mcgary.org>

3775 2002-07-10 Paul D. Smith <psmith@gnu.org>
3777 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3778 prerequisite list. A real SysV make will expand the entire
3779 prerequisites list _twice_: we don't do that as it's a big
3780 backward-compatibility problem. We only replace those specific
3783 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3784 references left in the list of prerequisites. Check for .POSIX as
3785 we record targets, so we can disable non-POSIX behavior while
3786 reading makefiles as well as running them.
3787 (eval): Check the prerequisite list to see if we have anything
3788 that looks like a SysV prerequisite variable reference.
3790 2002-07-09 Paul D. Smith <psmith@gnu.org>
3792 * doc/make.texi (Prerequisite Types): Add a new section describing
3793 order-only prerequisites.
3795 * read.c (uniquize_deps): If we have the same file as both a
3796 normal and order-only prereq, get rid of the order-only prereq,
3797 since the normal one supersedes it.
3799 2002-07-08 Paul D. Smith <psmith@gnu.org>
3801 * AUTHORS: Added Greg McGary to the AUTHORS file.
3802 * NEWS: Blurbed order-only prerequisites.
3803 * file.c (print_file): Show order-only deps properly when printing
3806 * maintMakefile: Add "update" targets for wget'ing the latest
3807 versions of various external files. Taken from Makefile.maint in
3810 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3811 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3813 2002-07-07 Paul D. Smith <psmith@gnu.org>
3815 * po/*.po: Remove. We'll use wget to retrieve them at release
3818 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3819 rather than a shell you get an exception. Make sure we look up
3820 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3822 * remake.c (notice_finished_file): Fix handling of -t flag.
3823 Patch provided by Henning Makholm <henning@makholm.net>.
3825 * implicit.c (pattern_search): Some systems apparently run short
3826 of stack space, and using alloca() in this function caused an
3827 overrun. I modified it to use xmalloc() on the two variables
3828 which seemed like they might get large. Fixes Bug #476.
3830 * main.c (print_version): Update copyright notice to conform with
3832 (print_usage): Update help output.
3834 * function.c (func_eval): Create a new make function, $(eval
3835 ...). Expand the arguments, put them into a buffer, then invoke
3836 eval_buffer() on the resulting string.
3837 (func_quote): Create a new function, $(quote VARNAME). Inserts
3838 the value of the variable VARNAME without expanding it any
3841 * read.c (struct ebuffer): Change the linebuffer structure to an
3842 "eval buffer", which can be either a file or a buffer.
3843 (eval_makefile): Move the code in the old read_makefile() which
3844 located a makefile into here: create a struct ebuffer with that
3845 information. Have it invoke the new function eval() with that
3847 (eval_buffer): Create a new function that creates a struct ebuffer
3848 that holds a string buffer instead of a file. Have it invoke
3849 eval() with that ebuffer.
3850 (eval): New function that contains the guts of the old
3851 read_makefile() function: this function parses makefiles. Obtains
3852 data to parse from the provided ebuffer. Some modifications to
3853 make the flow of the function cleaner and clearer. Still could
3854 use some work here...
3855 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3856 contents of the define/endef variable from the ebuffer.
3857 (readstring): Read the next line from a string-style ebuffer.
3858 (readline): Read the next line from an ebuffer. If it's a string
3859 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3862 * dep.h (eval_buffer): Prototype eval_buffer();
3864 * variable.c (do_variable_definition): Make sure that all
3865 non-target-specific variables are registered in the global set.
3866 If we're invoked from an $(eval ...) we might be inside a $(call
3867 ...) or other function which has pushed a variable scope; we still
3868 want to define our variables from evaluated makefile code in the
3871 2002-07-03 Greg McGary <greg@mcgary.org>
3873 * dep.h (struct dep) [ignore_mtime]: New member.
3874 [changed]: convert to a bitfield.
3875 * implicit.c (pattern_search): Zero ignore_mtime.
3876 * main.c (main, handle_non_switch_argument): Likewise.
3877 * rule.c (convert_suffix_rule): Likewise.
3878 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3879 (read_makefile): Parse '|' in prerequisite list.
3880 (uniquize_deps): Consider ignore_mtime when comparing deps.
3881 * remake.c (update_file_1, check_dep): Don't force remake for
3882 dependencies that have d->ignore_mtime.
3883 * commands.c (FILE_LIST_SEPARATOR): New constant.
3884 (set_file_variables): Don't include a
3885 prerequisite in $+, $^ or $? if d->ignore_mtime.
3888 2002-06-18 Paul D. Smith <psmith@gnu.org>
3890 * make.texinfo: Updates for next revision. New date/rev/etc.
3891 Recreate all Info menus. Change license on the manual to the GNU
3892 Free Documentation License. A number of typos.
3893 (Variables Simplify): Don't use "-" before it's defined.
3894 (Automatic Prerequisites): Rewrite the target example to work
3895 properly if the compile fails. Remove incorrect comments about
3896 how "set -e" behaves.
3897 (Text Functions): Move the "word", "wordlist", "words", and
3898 "firstword" functions here, from "File Name Functions".
3899 * make-stds.texi: Update from latest GNU version.
3900 * fdl.texi: (created) Import the latest GNU version.
3902 2002-06-06 Paul D. Smith <psmith@gnu.org>
3904 * variable.c (do_variable_definition): New function: extract the
3905 part of try_variable_definition() that actually sets the value
3906 into a separate function.
3907 (try_variable_definition): Call do_variable_definition() after
3908 parsing the variable definition string.
3909 (define_variable_in_set): Make the name argument const.
3911 * variable.h (enum variable_flavor): Make public.
3912 (do_variable_definition): Create prototype.
3914 * read.c (read_all_makefiles): Create a new built-in variable,
3916 (read_makefile): Add each makefile read in to this variable value.
3918 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3920 * Makefile.DOS.template: Tweak according to changes in the
3921 distribution. Add back the dependencies of *.o files.
3923 * configh.dos.template: Synchronize with config.h.in.
3925 2002-05-09 Paul D. Smith <psmith@gnu.org>
3927 * file.c (file_timestamp_now): Use K&R function declaration.
3929 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3930 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3931 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3932 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3933 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3934 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3935 nlist.n_name is a pointer rather than an array.
3937 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3938 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3939 * configure.in: Use it instead of the old version.
3941 * main.c (main): Prefer setvbuf() to setlinebuf().
3943 2002-05-08 Paul D. Smith <psmith@gnu.org>
3945 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3946 (loadavg_LDADD): Ditto.
3948 2002-04-29 Paul D. Smith <psmith@gnu.org>
3950 * expand.c (recursively_expand_for_file): Rename
3951 recursively_expand() to recursively_expand_for_file() and provide
3952 an extra argument, struct file. If the argument is provided, set
3953 the variable scope to that of the file before expanding.
3954 * variable.h (recursively_expand): Make this a macro that invokes
3955 recursively_expand_for_file() with a NULL file pointer.
3956 * variable.c (target_environment): Call the renamed function and
3957 provide the current file context.
3958 Fixes Debian bug #144306.
3960 2002-04-28 Paul D. Smith <psmith@gnu.org>
3962 Allow $(call ...) user-defined variables to be self-referencing
3963 without throwing an error. Allows implementation of transitive
3964 closures, among other possibly useful things.
3965 Requested by: Philip Guenther <guenther@sendmail.com>
3967 * variable.h (struct variable): Add a new field: exp_count, and
3968 new macros to hold its size and maximum value.
3969 (warn_undefined): Make this a macro.
3970 * variable.c (define_variable_in_set): Initialize it.
3971 * expand.c (recursively_expand): If we detect recursive expansion
3972 of a variable, check the exp_count field. If it's greater than 0
3973 allow the recursion and decrement the count.
3974 (warn_undefined): Remove this (now a macro in variable.h).
3975 * function.c (func_call): Before we expand the user-defined
3976 function, modify its exp_count field to contain the maximum
3977 number of recursive calls we'll allow. After the call, reset it
3980 2002-04-21 Paul D. Smith <psmith@gnu.org>
3982 Modified to use latest autoconf (2.53), automake (1.6.1), and
3983 gettext (0.11.1). We're using gettext's new "external" support,
3984 to avoid including libintl source with GNU make.
3986 * README.cvs: New file. Explain how to build GNU make from CVS.
3988 * configure.in: Modify checking for the system glob library.
3989 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3990 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3991 etc. will manage it correctly). Set an automake conditional
3992 USE_LOCAL_GLOB to decide whether to compile the glob library.
3994 * getloadavg.c (main): Include make.h in the "TEST" program to
3997 * Makefile.am: Remove special rules for loadavg. Replace them
3998 with Automake capabilities for building extra programs.
4000 * signame.c: This file does nothing if the system provide
4001 strsignal(). If not, it implements strsignal(). If the system
4002 doesn't define sys_siglist, then we make our own; otherwise we use
4004 * signame.h: Removed.
4006 * main.c (main): No need to invoke signame_init(). Update copyright.
4008 * ABOUT-NLS: Removed.
4009 * gettext.c: Removed.
4010 * gettext.h: Get a simplified copy from the gettext package.
4012 * i18n/*.po: Moved to po/.
4015 * config/*: Created. Contains package configuration helper files.
4016 * config.guess, config.sub: Moved to config directory.
4018 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4019 Rework to use new-style autoconf features. Use the "external"
4020 mode for gettext. Make the build.sh config file conditional on
4021 whether build.sh.in exists, to avoid autoconf errors.
4022 * acinclude.m4: Removed almost all macros as being obsolete.
4023 Rewrote remaining macros to use AC_DEFINE.
4024 * acconfig.h: Removed.
4026 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4027 conditional to handle customs support. Remove special handling
4030 2002-04-20 Paul D. Smith <psmith@gnu.org>
4032 * function.c (func_call): Don't mark the argument variables $1,
4033 etc. as recursive. They've already been fully expanded so
4034 there's no need to do it again, and doing so strips escaped $'s.
4035 Reported by Sebastian Glita <glseba@yahoo.com>.
4037 * remake.c (notice_finished_file): Walk through double-colon
4038 entries via the prev field, not the next field!
4039 Reported by Greg McGary <greg@mcgary.org>.
4041 * main.c (main): If the user specifies -q and asks for a specific
4042 target which is a makefile, we got an assert. In that case it
4043 turns out we should continue normally instead.
4045 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4047 * i18n/he.po: Installed a new translation.
4049 2002-01-07 Paul D. Smith <psmith@gnu.org>
4051 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4053 2001-12-04 Paul D. Smith <psmith@gnu.org>
4055 * i18n/ja.po: Installed an updated translation.
4057 2001-09-06 Paul Eggert <eggert@twinsun.com>
4059 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4060 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4062 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4064 (main): Get rid of any avoidable limit on stack size.
4066 2001-09-04 Paul D. Smith <psmith@gnu.org>
4068 * i18n/da.po: Installed an updated translation.
4070 2001-08-03 Paul D. Smith <psmith@gnu.org>
4072 * i18n/fr.po: Installed an updated translation.
4073 Resolves Debian bug #106720.
4075 2001-06-13 Paul D. Smith <psmith@gnu.org>
4077 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4080 2001-06-11 Paul D. Smith <psmith@gnu.org>
4082 * i18n/ko.po: Installed a new translation.
4084 2001-05-06 Paul D. Smith <psmith@gnu.org>
4086 Modify the EINTR handling.
4088 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4089 the way in which we manage the file descriptor/signal handler race
4090 trap to be more efficient.
4092 2001-05-06 Paul Eggert <eggert@twinsun.com>
4094 Restart almost all system calls that are interrupted, instead
4095 of worrying about EINTR. The lone exception is the read() for
4098 * configure.in (HAVE_SA_RESTART): New macro.
4099 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4100 * main.c (main): Use SA_RESTART instead of the old,
4101 nonstandard SA_INTERRUPT.
4103 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4104 * main.c (bsd_signal): New function or macro,
4105 if the implementation doesn't supply it.
4106 (The bsd_signal function will be in POSIX 1003.1-200x.)
4107 (HANDLESIG): Remove.
4108 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4110 * make.h (EINTR_SET): Remove.
4111 (SA_RESTART): New macro.
4113 * arscan.c (ar_member_touch): Don't worry about EINTR.
4114 * function.c (func_shell): Likewise.
4115 * job.c (reap_children, free_child, new_job): Likewise.
4116 * main.c (main): Likewise.
4117 * remake.c (touch_file, name_mtime): Likewise.
4119 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4120 if fstat failed with errno!=EINTR, the error was ignored.
4122 * job.c (set_child_handler_action_flags): New function.
4123 (new_job): Use it to temporarily clear the SIGCHLD action flags
4124 while reading the token.
4126 2001-05-02 Paul D. Smith <psmith@gnu.org>
4128 * job.c (start_job_command): Don't add define/endef per-line flags
4129 to the top-level flags setting.
4131 2001-04-03 Paul D. Smith <psmith@gnu.org>
4133 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4134 bit on error, so check for odd return values, not non-0 return
4136 (VMS_get_member_info): Calculate the timezone differences correctly.
4137 Reported by John Fowler <jfowler@nyx.net>.
4140 2001-03-14 Paul D. Smith <psmith@gnu.org>
4142 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4143 value before invoking define_variable().
4144 Reported by John Fowler <jfowler@nyx.net>.
4146 2001-02-07 Paul D. Smith <psmith@gnu.org>
4148 * read.c (record_target_var): If we reset the variable due to a
4149 command-line variable setting overriding it, turn off the "append"
4152 2001-01-17 Paul D. Smith <psmith@gnu.org>
4154 * variable.c (lookup_variable) [VMS]: When getting values from the
4155 environment, allocate enough space for the _value_ plus escapes,
4156 not enough space for the name plus escapes :-/.
4157 Reported by John Fowler <jfowler@nyx.net>.
4159 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4160 warnings that make generates, so it doesn't look like an error.
4161 Reported by Karl Berry <karl@gnu.org>.
4164 Fix for PR/2020: Rework appended target-specific variables. I'm
4165 fairly confident this algorithm is finally correct.
4167 * expand.c (allocated_variable_append): Rewrite. Instead of
4168 expanding each appended variable then adding all the expanded
4169 strings together, we append all the unexpanded values going up
4170 through the variable set contexts, then expand the final result.
4171 This behaves just like non-target-specific appended variable
4172 values, while the old way didn't in various corner cases.
4173 (variable_append): New function: recursively append the unexpanded
4174 value of a variable, walking from the outermost variable scope to
4176 * variable.c (lookup_variable): Remove the code that looked up the
4177 variable set list if the found variable was "append". We don't
4179 (lookup_variable_in_set): Make this non-static so we can use it
4181 (try_variable_definition): Use lookup_variable_in_set() rather
4182 than faking out current_variable_set_list by hand (cleanup).
4183 * variable.h: Add a prototype for the now non-static
4184 lookup_variable_in_set().
4186 2000-11-17 Paul D. Smith <psmith@gnu.org>
4188 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4189 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4190 before throwing a fit.
4192 2000-11-17 Paul D. Smith <psmith@gnu.org>
4194 * read.c (readline): CRLF calculations had a hole, if you hit the
4195 buffer grow scenario just right. Reworked the algorithm to avoid
4196 the need for len or lastlen at all. Problem description with
4197 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4199 2000-10-24 Paul D. Smith <psmith@gnu.org>
4201 * gettext.c (SWAP): Declare this with the prototype, otherwise
4202 some systems don't work (non-32-bit? Reported for Cray T3E).
4203 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4205 2000-10-05 Paul D. Smith <psmith@gnu.org>
4207 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4208 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4210 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4212 2000-09-22 Paul D. Smith <psmith@gnu.org>
4214 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4215 parts of the real gettext.h here, and we expect to really include
4216 the real gettext.h later. If we keep this #define, it's ignored.
4218 2000-09-21 Paul D. Smith <psmith@gnu.org>
4220 * main.c (log_working_directory): Rework the text to use complete
4221 sentences, to make life simpler for the translators.
4223 2000-08-29 Paul D. Smith <psmith@gnu.org>
4225 * file.c (remove_intermediates): Print a debug message before we
4226 remove intermediate files, so the user (if she uses -d) knows
4229 2000-08-21 Paul D. Smith <psmith@gnu.org>
4231 * variable.c (try_variable_definition): Change how we handle
4232 target-specific append variable defns: instead of just setting the
4233 value, expand it as an append _but_ only within the current
4234 target's context. Otherwise we lose all but the last value if the
4235 variable is appended more than once within the current target
4236 context. Fixes PR/1831.
4238 2000-08-16 Paul D. Smith <psmith@gnu.org>
4240 * function.c (func_shell): Nul-terminate the buffer before
4241 printing an exec error message (just in case it's not!).
4242 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4244 2000-07-25 Paul D. Smith <psmith@gnu.org>
4246 * job.c (construct_command_argv_internal): Add "~" to the list of
4247 sh_chars[] which disallow optimizing out the shell call.
4249 2000-07-23 Paul Eggert <eggert@twinsun.com>
4251 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4252 supersedes --disable-nsec-timestamps.
4253 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4254 * README: Remove --disable-nsec-timestamps.
4256 * filedef.h (struct file.low_resolution_time): New member.
4257 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4258 * remake.c (update_file_1):
4259 Avoid spurious rebuilds due to low resolution time stamps,
4260 generalizing the earlier code that applied only to archive members.
4261 (f_mtime): Archive members always have low resolution time stamps.
4263 * configure.in: Remove --disable-nsec-timestamps, as this has
4264 been superseded by .LOW_RESOLUTION_TIME.
4266 2000-07-23 Paul Eggert <eggert@twinsun.com>
4268 * configure.in (enable_nsec_timestamps): Renamed from
4269 make_cv_nsec_timestamps, since enable/disable options
4270 shouldn't be cached.
4272 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4273 and Paul Eggert <eggert@twinsun.com>
4275 * file.c (file_timestamp_now):
4276 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4277 so that clock_gettime is not linked unless needed.
4279 * filedef.h (FILE_TIMESTAMP_HI_RES):
4280 Remove definition; "configure" now does this.
4282 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4283 to before high resolution file timestamp check,
4284 since that check now uses uintmax_t.
4285 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4286 high resolution file timestamps.
4287 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4288 so that we don't link in clock_gettime unnecessarily.
4290 2000-07-17 Paul D. Smith <psmith@gnu.org>
4292 * i18n/ja.po: New version of the translation file.
4294 2000-07-07 Paul D. Smith <psmith@gnu.org>
4296 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4297 the offset calculation.
4298 (name_mtime): Replace EINTR test with EINTR_SET macro.
4300 2000-07-07 Paul Eggert <eggert@twinsun.com>
4304 * remake.c (update_file_1):
4305 Avoid spurious rebuilds of archive members due to their
4306 timestamp resolution being only one second.
4307 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4308 the clock's resolution being lower than file timestamps'.
4309 When warning about future timestamps, report only the discrepancy,
4310 not the absolute value of the timestamp and the current time.
4312 * file.c (file_timestamp_now): New arg RESOLUTION.
4313 * filedef.h (file_timestamp_now): Likewise.
4314 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4316 2000-07-05 Paul D. Smith <psmith@gnu.org>
4318 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4319 to listp. Fixes PR/1793.
4321 2000-06-26 Paul Eggert <eggert@twinsun.com>
4323 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4325 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4327 * remake.c (f_mtime): Remove unused var memtime.
4329 2000-06-25 Martin Buchholz <martin@xemacs.org>
4331 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4332 Ran spell-check on make.texinfo.
4334 2000-06-23 Paul D. Smith <psmith@gnu.org>
4336 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4337 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4338 * make.h: Define these macros.
4340 * Version 3.79.1 released.
4342 * configure.in: Add a new option, --disable-nsec-timestamps, to
4343 avoid using sub-second timestamps on systems that support it. It
4344 can lead to problems, e.g. if your makefile relies on "cp -p".
4345 * README.template: Document the issue with "cp -p".
4347 * config.guess, config.sub: Updated.
