553 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
555 * implicit.c (pattern_search): Merge three parallel arrays,
556 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
557 of struct TRYRULE. In the old version the latter two arrays
558 had insufficient length.
560 2009-09-24 Paul Smith <psmith@gnu.org>
562 * implicit.c (pattern_search): Add back support for order-only
563 prerequisites for secondary expansion implicit rules, that were
564 accidentally dropped. If we find a "|", enable order-only mode
565 and set IGNORE_MTIME on all deps that are seen afterward.
566 (pattern_search): Fix memory leaks: for intermediate files where
567 we've already set the file variable and pattern variable sets, be
568 sure to either save or free them as appropriate.
570 2009-09-23 Paul Smith <psmith@gnu.org>
572 Rework the way secondary expansion is stored, for efficiency.
573 This changes secondary expansion so that ONLY WHEN we know we have
574 a possibility of needing secondary expansion, do we defer the
575 secondary expansion. This means more parsing the deps but we use
576 a lot less memory (due to the strcache). Also, this fixes
579 * read.c (eval): Don't parse the dep string here anymore.
580 (record_files): Take the dep argument as an unparsed string. If
581 secondary expansion is enabled AND the prereq string has a '$' in
582 it, then set NEED_2ND_EXPANSION and keep the entire string.
583 Otherwise, parse the dep string here to construct the dep list
584 with the names in the strcache.
586 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
587 duplicate the name string (others are in the strcache).
589 * implicit.c: Remove struct idep and free_idep_chain(): unused.
590 (struct patdeps): New structure to store prereq information.
591 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
592 which prerequisites need expansion, and expand only those.
594 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
595 and enter_prereqs(). split_prereqs() takes a fully-expanded string
596 and splits it into a DEP list, handling order-only prereqs.
597 (enter_prereqs): This function enters a list of DEPs into the file
598 database. If there's a stem defined, expand any pattern chars.
599 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
600 set. Use the above functions.
601 (snap_deps): Only perform second expansion on prereqs that need it,
602 as defined by the NEED_2ND_EXPANSION flag.
603 (print_prereqs): New function to print the prereqs
604 (print_file): Call print_prereqs() rather than print inline.
606 * hash.h (STRING_COMPARE): Take advantage of strcache() by
608 (STRING_N_COMPARE): Ditto.
609 (ISTRING_COMPARE): Ditto.
611 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
612 (parse_file_seq): Return void*
613 * read.c (parse_file_seq): Return void*.
614 (eval): Invoke macroized version of parse_file_seq()
615 * default.c (set_default_suffixes): Ditto.
616 * file.c (split_prereqs): Ditto.
617 * function.c (string_glob): Ditto.
618 * main.c (main): Ditto.
619 * rule.c (install_pattern_rule): Ditto.
621 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
623 2009-09-16 Paul Smith <psmith@gnu.org>
625 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
627 * dep.h: Create alloc_dep() / free_dep() macros.
629 * implicit.c (pattern_search): Take advantage of the new
630 parse_file_seq() to add the directory prefix to each prereq.
632 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
633 all. Avoid reversing chains. Support adding prefixes.
634 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
635 cached/non-cached results.
636 (eval): Remove multi_glob() & invoke new parse_file_seq().
637 * rule.c (install_pattern_rule): Ditto.
638 * main.c (main): Ditto.
639 * implicit.c (pattern_search): Ditto.
640 * function.c (string_glob): Ditto.
641 * file.c (parse_prereqs): Ditto.
642 * default.c (set_default_suffixes): Ditto.
644 * variable.c (parse_variable_definition): Don't run off the end of
645 the string if it ends in whitespace (found with valgrind).
647 * commands.c (set_file_variables): Keep space for all targets in
648 $? if -B is given (found with valgrind).
650 2009-09-15 Paul Smith <psmith@gnu.org>
652 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
653 (xcalloc): Add new function.
654 * make.h: New declarations.
656 * ar.c (ar_glob_match): New calling method for concat().
657 * main.c (main): Ditto.
658 (decode_env_switches): Ditto.
659 * read.c (eval_makefile): Ditto.
660 (tilde_expand): Ditto.
661 (parse_file_seq): Ditto.
662 * variable.c (target_environment): Ditto.
663 (sync_Path_environment): Ditto.
665 * ar.c (ar_glob_match): Use xcalloc().
666 * dir.c (file_impossible): Ditto.
667 * file.c (enter_file): Ditto.
668 * job.c (new_job): Ditto.
669 * read.c (parse_file_seq): Ditto.
670 * vmsfunctions.c (opendir): Ditto.
672 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
674 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
675 inside the loop that looks up environment for PATH.
677 2009-08-31 Eli Zaretskii <eliz@gnu.org>
679 * function.c (windows32_openpipe): Update envp after calling
680 sync_Path_environment.
682 2009-08-02 Paul Smith <psmith@gnu.org>
684 * remake.c (notice_finished_file): Ensure file->cmds is not null
685 before looping through them. Fixes Savannah bug #21824.
687 * doc/make.texi (Wildcard Examples): Clarify when objects is
688 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
689 (Include): Clarify the behavior of -include.
690 Fixes Savannah bug #18963.
692 2009-08-01 Paul Smith <psmith@gnu.org>
694 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
695 etc. come on the command line. Fixes Savannah bug #27093.
697 * expand.c (expand_argument): If the argument is large enough use
698 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
700 * variable.c (do_variable_definition): Avoid using alloca() to
701 hold values, which can be large. Fixes Savannah bug #23960.
703 * job.c (new_job): Use memmove() instead of strcpy() since both
704 pointers are in the same memory block. Fixes Savannah bug #27148.
705 Patch by Petr Machata.
707 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
709 * job.c (construct_command_argv_internal): Add "ulimit" and
710 "unset" to the sh_cmds for Unixy shells.
712 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
714 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
715 that set make_cv_sys_gnu_glob, so they are also correctly set
716 when the cache has been populated before.
718 2009-07-04 Eli Zaretskii <eliz@gnu.org>
720 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
721 exist, as realpath(3) does where it's supported.
723 2006-07-04 Eli Zaretskii <eliz@gnu.org>
725 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
726 (abspath): Support systems that define HAVE_DOS_PATHS (have
727 drive letters in their file names). Use IS_PATHSEP instead of a
728 literal '/' comparison. Fixes Savannah bug #26886.
730 2009-06-14 Paul Smith <psmith@gnu.org>
732 * remake.c (update_file_1): Remember the original file we marked
733 as updating, so we can clear that flag again. If we find a target
734 via vpath, FILE might change.
735 (check_dep): Ditto. Fixes Savannah bug #13529.
736 Patch by Reid Madsen <reid.madsen@tek.com>.
738 2009-06-13 Paul Smith <psmith@gnu.org>
740 * doc/make.texi (MAKEFILES Variable): Be explicit that files
741 included by MAKEFILES cannot give default goals.
742 * read.c (eval): If set_default is not set, pass the no-default-goal
743 value when we read included makefiles. Fixes Savannah bug #13401.
745 * ar.c (ar_name): Ensure that targets with empty parens aren't
746 considered archive member references: archive members must have a
747 non-empty "member" string. Fixes Savannah bug #18435.
749 * function.c (string_glob): Rely on multi_glob() to determine
750 whether files exist or not. Remove call to file_exists_p() which
751 is not always correct. Fixes Savannah bug #21231.
752 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
753 then only files that really exist will be returned.
754 * dep.h: Add new argument to multi_glob().
755 * rule.c (install_pattern_rule): Ditto.
756 * read.c (eval): Ditto.
757 * main.c (main): Ditto.
758 * implicit.c (pattern_search): Ditto.
759 * file.c (parse_prereqs): Ditto.
760 * default.c (set_default_suffixes): Ditto.
762 2009-06-09 Paul Smith <psmith@gnu.org>
764 * commands.c (set_file_variables): If always_make_flag is set,
765 always add the prereq to $?. Fixes Savannah bug #17825.
767 * remake.c (update_file_1): When rebuilding deps of FILE, also try
768 to rebuild the deps of all the also_make targets for that file.
769 Fixes Savannah bug #19108.
771 * implicit.c (pattern_search): Undo test for is_target, added by
772 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
773 Rule Search Algorithm". Fixes Savannah bug #17752.
775 * main.c (clean_jobserver): Clear the jobserver_fds options and
776 set job_slots to the default when we clean up.
777 (define_makeflags): Return the new MAKEFLAGS value.
778 (main): Reset MAKEFLAGS in the environment when we re-exec.
779 Fixes Savannah bug #18124.
781 2009-06-08 Paul Smith <psmith@gnu.org>
783 * read.c (eval): Collapse continuations post-semicolon on target-
784 specific variables. Fixes Savannah bug #17521.
786 2009-06-07 Paul Smith <psmith@gnu.org>
788 * job.c (reap_children): For older systems without waitpid() (are
789 there any of these left?) run wait(2) inside EINTRLOOP to handle
790 EINTR errors. Fixes Savannah bug #16401.
792 * (various): Debug message cleanup. Fixes Savannah bug #16469.
794 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
796 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
797 not the end, to catch second expansion $(eval ...) defining new
798 target/prereq relationships during snap_deps.
799 Fixes Savannah bug #24622.
801 * read.c (record_files): The second-expansion "f->updating" hack
802 was not completely correct: if assumed that the target with
803 commands always had prerequisites; if one didn't then the ordering
804 was messed up. Fixed for now to use f->updating to decide whether
805 to preserve the last element in the deps list... but this whole
806 area of constructing and reversing the deps list is too confusing
807 and needs to be reworked. Fixes Savannah bug #21198.
809 2009-06-06 Paul Smith <psmith@gnu.org>
811 * hash.c (hash_insert): Remove useless test for NULL.
812 Fixes Savannah bug #21823.
814 * make.h: Move SET_STACK_SIZE determination to make.h.
815 * main.c (main): New global variable, STACK_LIMIT, holds the
816 original stack limit when make was started.
817 * job.c (start_job_command): Reset the stack limit, if we changed it.
818 Fixes Savannah bug #22010.
820 * remake.c (check_dep): Only set the target's state to not-started
821 if it's not already running. Found this while testing -j10 builds
822 of glibc: various targets were being rebuilt multiple times.
823 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
826 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
827 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
830 2009-06-04 Paul Smith <psmith@gnu.org>
832 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
834 * maintMakefile: Modify access of config and gnulib Savannah
835 modules to use GIT instead of CVS.
837 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
838 Fixes Savannah bug #24655.
840 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
841 this can happen during some invocations of $(eval ...) for example.
842 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
844 2009-06-02 Paul Smith <psmith@gnu.org>
846 * configure.in: Check for fileno()
847 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
848 for the makefile file so invocations of $(shell ...) don't inherit it.
849 Fixes Savannah bug #24277.
851 2009-06-01 Paul Smith <psmith@gnu.org>
853 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
854 expansion was handled incorrectly. Rework the default goal
855 handling to save the variable only. Remove default_goal_file and
857 * read.c (eval): Check default_goal_var, not default_goal_name.
858 * read.c (record_target_var): Don't check default_goal_file here.
860 2009-05-31 Paul Smith <psmith@gnu.org>
862 * main.c (main): Expand the .DEFAULT_GOAL variable before using
863 it, and if the multi_glob() returns nothing (say it expanded to
864 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
866 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
867 $(and ..) to the reference. Fixes Savannah bug #25694.
869 * make.1: Be clear that some recipes will be executed even with -n.
870 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
872 * doc/make.texi (Override Directive): Make more clear how
873 overrides and appends interact.
874 Elucidates part of Savannah bug #26207.
876 * read.c (record_target_var): Don't reset the origin on
877 target-specific variables; try_variable_definition() will handle
878 this correctly. Fixes Savannah bug #26207.
880 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
881 Fixes Savannah bug #25712.
883 * implicit.c (pattern_search): Keep a pointer to the beginning of
884 the filename and save that instead of the constructed pointer.
885 Fixes Savannah bug #26593.
886 Patch by Mark Seaborn <mrs@mythic-beasts.com>
888 2009-05-30 Paul Smith <psmith@gnu.org>
890 * doc/make.texi (Multi-Line): Add a description of the new abilities
891 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
892 "command sequence" vs. "recipe" syntax.
893 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
894 after a define, to create variables with those flavors.
896 2009-05-25 Paul Smith <psmith@gnu.org>
898 Reworked the parser for variable assignments to allow multiple
899 modifiers, and in any order. Also allows variable and
900 prerequisites to be modifier names ('export', 'private', etc.)
902 * NEWS: Add notes about user-visible changes.
904 * read.c (struct vmodifiers): Remember what modifiers were seen.
905 (parse_var_assignment): New function to parse variable assignments.
906 (eval): Call the new function. Handle variable assignments earlier.
908 * variable.c (parse_variable_definition): Only parse; don't create var.
909 (assign_variable_definition): Call parse, then create the var.
911 2009-05-24 Paul Smith <psmith@gnu.org>
913 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
914 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
916 2009-03-14 Eli Zaretskii <eliz@gnu.org>
918 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
919 Fixes Savannah bug #25412.
921 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
922 prototype for xmalloc.
923 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
924 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
925 Loop over an array of extensions, instead of duplicating the same
926 code inline. Use SearchPath followed by CreateFile, instead of
927 the obsolete OpenFile. Fixes Savannah bug #17277.
928 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
929 to `find_file'. Fixes Savannah bug #25662.
931 2009-03-07 Eli Zaretskii <eliz@gnu.org>
933 * function.c (func_shell): Don't close pipedes[1] if it is -1.
934 Fixes Savannah bug #20495.
936 2009-02-28 Ralf Wildenhues <address@hidden>
938 * doc/make.texi (Instead of Execution): Document interaction of
939 -t with phony targets.
941 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
943 Introduce a new keyword "private" which applies to target-specific
944 variables and prevents their values from being inherited.
946 * variable.h (struct variable): Add private_var flag to each variable.
947 Add a flag to specify which list entry switches to the parent target.
948 * variable.c (define_variable_in_set): Initialize private_var flag.

967 2008-09-30 Eli Zaretskii <eliz@gnu.org>
969 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
972 * w32/subproc/build.bat (GCCBuild): Likewise.
974 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
976 * job.c (construct_command_argv_internal): Avoid extra backslash
977 in batch-mode Unixy shells. Under DB_JOBS, display the contents
980 2008-05-31 Eli Zaretskii <eliz@gnu.org>
982 * README.W32.template: Remove obsolete text about non-support for
983 -jN without Unixy shell. Remove obsolete text about not supplying
984 Visual Studio project files (we do supply them). Modify text to
985 prefer GCC builds to MSC builds.
987 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
989 * doc/make.texi (Empty Targets): Fix typo.
991 2008-03-27 Paul Smith <psmith@gnu.org>

1004 `value' field is NULL.
1006 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1008 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1010 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1011 (TEXINFOS): Value changed to `doc/make.texi'.
1012 (.SUFFIXES): Use .texi instead of .texinfo.
1013 (make.info, make.dvi): Depend on doc/make.texi.
1014 (.texi.info): New target, instead of ".texinfo.info". Change -I
1015 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1016 (.texi): New target, instead of ".texinfo". Change -I switch to
1017 $(MAKEINFO) to look in doc/. Use --no-split.
1018 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1019 switch to $(MAKEINFO) to look in doc/.
1020 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1021 "*.i[0-9][0-9]" (due to --no-split above).
1022 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1023 (html, make_1.html): New targets.
1024 (.PHONY): Add "html".
1025 (.SUFFIXES): Add .html.
1027 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1029 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1030 HAVE_DECL_SYS_SIGLIST.
1032 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1033 build does not use child_execute_job.
1035 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1036 export the SHELL environment variable to the child.
1038 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1040 * config.h.W32: Include sys/types.h.
1041 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1043 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1044 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1047 2007-11-04 Paul Smith <psmith@gnu.org>
1049 * doc/make.texi: Convert references to "commands", "command
1050 lines", and "command script" to "recipe".
1052 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1055 2007-10-27 Bruno Haible <bruno@clisp.org>
1057 * remake.c (f_mtime): Print time difference values between 100 and
1058 ULONG_MAX in fixed-point notation rather than in exponention notation.
1060 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1062 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1063 a more complex value than a simple shell: if it's not a default
1064 shell now then expand it and see if is a default shell then.
1066 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1068 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1069 pathnames, with const strings.
1070 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1071 from the template (used for building from CVS, not a dist).
1073 2007-10-10 Paul Smith <psmith@gnu.org>
1075 * make.h: Add a prototype for w32_kill() (change suggested by

1090 2007-09-11 Paul Smith <psmith@gnu.org>
1092 * doc/make.texi (Special Variables): Moved this into the "How to
1093 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1098 (Rule Syntax): Ditto.
1099 (Command Syntax): Ditto.
1100 (Error Messages): Ditto.
1102 2007-09-10 Paul Smith <psmith@gnu.org>
1104 * commands.c (print_commands): Don't print an extra line in the
1105 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1107 * read.c (construct_include_path): Add the full string to the cache; we
1108 were chopping the last char.
1110 * NEWS: Announce the .RECIPEPREFIX special variable.
1111 * variable.c (lookup_special_var): Rename from handle_special_var().
1112 (lookup_variable): Call the new name.
1113 (set_special_var): New function: handle setting of special variables.
1114 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1118 * main.c (main): Create the .RECIPEPREFIX special variable.
1119 * read.c (eval): Remove the cmd_prefix characters from the command
1120 scripts here, so they're not stored in the commands array at all,
1121 rather than waiting and stripping them out during command construction.
1122 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1124 2007-08-15 Paul Smith <psmith@gnu.org>
1126 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1127 file has had the section info removed, so add some to make.texi
1128 before we include it.
1130 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1132 * remake.c (check_dep): Reset the target state for intermediate
1133 files. They might have been considered before but not updated

1183 Add support for Objective C. Fixes Savannah bug #16389.
1184 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1186 * function.c (func_lastword): Initialize p.
1188 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):

1190 Dave Korn <dave.korn@artimi.com>
1192 2007-05-08 Paul Smith <psmith@gnu.org>
1194 Fix Savannah bug #19656:
1196 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1198 * make.h: Change all case-insensitive string compares to use
1199 strcasecmp() (from POSIX). If we don't have that but do have one
1200 of the others, define strcasecmp to be one of those instead. If
1201 we don't have any, declare a prototype for our own version.
1203 * misc.c (strcasecmp): Use this if we can't find any native
1204 case-insensitive string comparison function.
1205 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1206 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1208 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1209 strcasecmp() instead of stricmp().
1210 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1211 instead of strcmpi().
1212 * acinclude.m4: Remove the strcasecmp() check from here.
1214 2007-03-21 Paul Smith <psmith@gnu.org>
1216 * configure.in: Don't turn on case-insensitive file system support
1217 if --disable-... is given. Fixes Savannah bug #19348.
1219 2007-03-19 Paul Smith <psmith@gnu.org>
1221 * ALL: Use the strcache for all file name strings, or other
1222 strings which we will never free. The goal is to save memory by
1223 avoiding duplicate copies of strings. However, at the moment this
1224 doesn't save much memory in most situations: due to secondary
1225 expansion we actually save prerequisite lists twice (once before
1226 the secondary expansion, and then again after it's been parsed
1227 into individual file names in the dep list). We will resolve this
1228 in a future change, by doing the parsing up-front for targets
1229 where secondary expansion is not set.
1231 Moving things into the strcache also allows us to use const
1232 pointers in many more places.
1234 2007-01-03 Paul Smith <psmith@gnu.org>
1236 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1237 the function, not just the first. Fixes Savannah bug #18680.
1239 2006-11-18 Paul Smith <psmith@gnu.org>
1241 * strcache.c (strcache_add_len): Don't allocate a new buffer
1242 unless the string is not already nil-terminated. Technically this
1243 is a violation of the standard, since we may be passed an array
1244 that is not long enough to test one past. However, in make this
1245 is never true since we only use nil-terminated strings or
1246 sub-strings thereof.
1248 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1250 * main.c: New global cmd_prefix, defaults to '\t'.
1251 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1254 * dir.c: Constified.
1255 (dir_contents_file_exists_p): Check for an error return from
1256 readdir(), just in case.
1258 * commands.c: Constified.
1259 * default.c: Constified.
1260 * expand.c: Constified.
1261 * function.c: Partial constification.

1266 * w32/pathstuff.c: Partial constification.
1268 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1270 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1271 backslashes and drive letters as absolute.
1273 2006-10-22 Paul Smith <psmith@gnu.org>

1277 2006-10-21 Paul Smith <psmith@gnu.org>
1280 * arscan.c: Constified.
1282 2006-09-30 Paul Smith <psmith@gnu.org>
1284 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1285 point to lastword since the example was updated.
1286 Fixes Savannah bug #16304.
1287 (Secondary Expansion): Correct example description.
1288 Fixes Savannah bug #16468.
1289 (Makefile Contents): Clarify that comments cannot appear within
1290 variable references or function calls.
1291 Fixes Savannah bug #16577.
1292 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1293 Fixes Savannah bug #17701.
1294 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1296 prerequisites. Fixes Savannah bug #17880.
1297 (Rule Syntax): "lise" -> "list"
1298 (Multiple Rules): ... -> @dots{}
1299 (Splitting Lines): ditto.
1301 * remake.c (update_file_1): Prereqs that don't exist should be
1302 considered changed, for the purposes of $?.
1303 Fixes Savannah bug #16051.
1305 * make.1: Remove extraneous "+".
1306 Fixes Savannah bug #16652.

1344 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1345 that don't have extended grep.
1346 (cvsclean): Use $(PERL) instead of perl.
1348 2006-04-09 Paul D. Smith <psmith@gnu.org>
1350 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1352 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1353 inner-scope variables don't mask outer-scope variables.
1355 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1358 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1359 values from memory allocation functions: they return void* and so
1360 don't need to be cast. Also remove (char *) casts of arguments to

1414 Declare and define sh_chars_sh[].
1416 2006-03-23 Paul D. Smith <psmith@gnu.org>
1418 * configure.in: Look for build.sh.in in $srcdir so it will be
1419 built for remote configurations as well.
1421 * Makefile.am: Make sure to clean up build.sh during distclean.
1422 Fixes Savannah bug #16166.
1424 * misc.c (log_access): Takes a const char *.
1425 * function.c (fold_newlines): Takes an unsigned int *.

1430 * implicit.c (pattern_search): Call set_file_variables only
1431 if we have prerequisites that need second expansion. Fixes
1432 Savannah bug #16140.
1434 2006-03-19 Paul D. Smith <psmith@gnu.org>
1436 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1437 memory on hosts that don't support it directly.

1440 make sure I don't forget any).
1442 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1444 (die): Cleanup code was removed from here; call the new function.
1445 (main): If we are re-execing, clean up the jobserver first so we
1446 don't leak file descriptors.

1459 (copy_dep_chain): Copy stem.
1460 (free_dep_chain): Use free_dep.
1461 * read.c (record_files): Store stem in the dependency line.
1462 * file.c (expand_deps): Use stem stored in the dependency line. Use

1476 Fixes Savannah bug #15913.
1478 2006-03-09 Paul Smith <psmith@gnu.org>
1480 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1481 listed non-existent files as changed. Turns out there's a bug in
1482 the Linux kernel builds which means that this change causes
1483 everything to rebuild every time. We will re-introduce this fix
1484 in the next release, to give them time to fix their build system.
1485 Fixes Savannah bug #16002.
1486 Introduces Savannah bug #16051.

1505 * commands.c (set_file_variables): Realloc, not malloc, the static
1506 string values to avoid memory leaks.
1508 * expand.c (recursively_expand_for_file): Only set reading_file to
1509 an initialized value.
1511 * implicit.c (pattern_search): We need to make a copy of the stem
1512 if we get it from an intermediate dep, since those get freed.
1514 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1516 (enter_file) [VMS]: Ditto.

1521 * job.c (construct_command_argv_internal): Fix last change.
1523 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1524 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1525 the calls to _beginthreadex.
1527 * expand.c (recursively_expand_for_file): Initialize `save' to
1528 prevent compiler warnings.
1530 2006-02-18 Eli Zaretskii <eliz@gnu.org>

1534 script file stream to text mode.

1538 * variable.c (merge_variable_set_lists): Don't try to merge the
1539 global_setlist. Not only is this useless, but it can lead to
1540 circularities in the linked list, if global_setlist->next in one
1541 list gets set to point to another list which also ends in

1547 Fix for Savannah bug #106.

1550 expanding. If no variable is being expanded, it's the same as
1552 * make.h (expanding_var): Declare it.
1553 * expand.c (recursively_expand_for_file): Set expanding_var to the
1554 current variable we're expanding, unless there's no file info in
1555 it (could happen if it comes from the command line or a default
1556 variable). Restore it before we exit.

1572 an impossible file, free it.

1574 * variable.h: Declare it.
1576 * read.c (read_all_makefiles): Makefile names are kept in the
1577 strcache, so there's never any need to alloc/free them.

1581 archive support is enabled.

1596 A new internal capability: the string cache is a read-only cache
1597 of strings, with a hash table interface for fast lookup. Nothing
1598 in the cache will ever be freed, so there's no need for reference
1599 counting, etc. This is the beginning of a full solution for
1600 Savannah bug #15182, but for now we only store makefile names here.
1602 * strcache.c: New file. Implement a read-only string cache.
1603 * make.h: Add prototypes for new functions.
1604 * main.c (initialize_global_hash_tables): Initialize the string cache.
1605 (print_data_base): Print string cache stats.
1606 * read.c (eval_makefile): Use the string cache to store makefile
1607 names. Rewrite the string allocation to be sure we free everything.
1609 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1611 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1612 directory time stamp didn't change, except on FAT filesystems.
1613 Suggested by J. David Bryan <jdbryan@acm.org>.
1615 2006-02-09 Paul D. Smith <psmith@gnu.org>
1617 * function.c (func_or): Implement a short-circuiting OR function.
1618 (func_and): Implement a short-circuiting AND function.
1619 (function_table_init): Update the table with the new functions.
1620 * doc/make.texi (Conditional Functions): Changed the "if" section
1621 to one on general conditional functions. Added documentation for
1622 $(and ...) and $(or ...) functions.
1623 * NEWS: Note new $(and ...) and $(or ...) functions.
1625 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1627 * job.h (struct child): Add the dontcare bitfield.
1628 * job.c (new_job): Cache dontcare flag.
1629 * job.c (reap_children): Use cached dontcare flag instead of the
1630 one in struct file. Fixes Savannah bug #15641.
1632 2006-02-06 Paul D. Smith <psmith@gnu.org>
1634 * vpath.c (selective_vpath_search): If the file we find has a
1635 timestamp from -o or -W, use that instead of the real time.
1636 * remake.c (f_mtime): If the mtime is a special token from -o or
1637 -W, don't overwrite it with the real mtime.
1638 Fixes Savannah bug #15341.
1640 Updates from Markus Mauhart <qwe123@chello.at>:
1642 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1648 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1649 * README.cvs: Updates for building from CVS.
1651 2006-02-05 Paul D. Smith <psmith@gnu.org>
1653 * file.c (enter_file): Keep track of the last double_colon entry,
1654 to avoid walking the list every time we want to add a new one.
1655 Fixes Savannah bug #15533.
1656 * filedef.h (struct file): Add a new LAST pointer.
1658 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1659 the comparison. For 64-bits systems the result of the subtraction
1660 might not fit into an int. Use comparison instead.
1661 Fixes Savannah bug #15534.
1663 * doc/make.texi: Update the chapter on writing commands to reflect
1664 the changes made in 3.81 for backslash/newline and SHELL handling.

1684 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1686 * remake.c (update_goal_chain): Set g->changed instead of
1687 incrementing it, as it is only 8-bit wide, and could overflow if
1688 many commands got started in update_file.
1690 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1692 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1693 MAXIMUM_WAIT_OBJECTS.
1694 (process_wait_for_any_private): Change dimension of handles[]
1695 array to MAXIMUM_WAIT_OBJECTS.
1696 (process_used_slots): New function.
1697 (process_register): Don't register more processes than the
1698 available number of slots.
1699 (process_easy): Don't start new processes if all slots are used up.
1701 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1702 are already more children than sub_proc.c can handle, behave as if
1703 the load were too high.
1704 (start_job_command): Fix a typo in error message when process_easy
1707 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1709 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1710 the shell is not sh.exe.
1712 * job.c (create_batch_file): Renamed from create_batch_filename;
1713 all callers changed. Don't close the temporary file; return its
1714 file descriptor instead. New arg FD allows to return the file
1716 (construct_command_argv_internal): Use _fdopen instead of fopen to
1717 open the batch file.
1719 2006-01-04 Paul D. Smith <psmith@gnu.org>
1721 * readme.vms: Updates for case-insensitive VMS file systems from
1722 Hartmut Becker <Hartmut.Becker@hp.com>.

1742 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1743 disable warnings for MSC.
1744 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1746 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1748 * doc/make.texi (Execution): Add a footnote about changes in
1749 handling of backslash-newline sequences. Mention the differences
1750 on MS-DOS and MS-Windows.
1752 * NEWS: More details about building the MinGW port and a pointer
1753 to README.W32. Fix the section name that describes the new
1754 backward-incompatible processing of backslash-newline sequences.
1755 The special processing of SHELL set to "cmd" is only relevant to
1756 MS-Windows, not MS-DOS.
1758 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1760 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1761 to DWORD, to avoid compiler warnings.
1762 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1763 use %ld in format, to avoid compiler warnings.

1777 * read.c (record_target_var): Initialize variable's export field
1778 with v_default instead of leaving it "initialized" by whatever
1779 garbage happened to be on the heap.
1781 2005-12-12 Paul D. Smith <psmith@gnu.org>
1783 * make.1: Fix some display errors and document all existing options.
1784 Patch by Mike Frysinger <vapier@gentoo.org>.
1786 2005-12-11 Paul D. Smith <psmith@gnu.org>
1788 * implicit.c (pattern_search): If 2nd expansion is not set for
1789 this implicit rule, replace the pattern with the stem directly,
1790 and don't re-expand the variable list. Along with the other
1791 .SECONDEXPANSION changes below, fixes bug #13781.
1793 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1795 * implicit.c (pattern_search): Mark other files that this rule
1796 builds as targets so that they are not treated as intermediates
1797 by the pattern rule search algorithm. Fixes bug #13022.
1799 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1801 * remake.c (notice_finished_file): Propagate the change of
1802 modification time to all the double-colon entries only if

1821 * read.c (record_files): Don't set deps flags if there are no deps.
1822 * maintMakefile: We only need to build the templates when we are
1823 creating a distribution, so don't do it for "all".
1825 2005-10-24 Paul D. Smith <psmith@gnu.org>
1827 Make secondary expansion optional: its enabled by declaring the
1828 special target .SECONDEXPANSION.
1830 * NEWS: Update information on second expansion capabilities.
1831 * doc/make.texi (Secondary Expansion): Document the
1832 .SECONDEXPANSION special target and its behavior.

1834 prerequisite list was found in a static pattern rule.
1835 (free_dep_chain): Declare a prototype.
1836 * file.c (parse_prereqs): New function: break out some complexity
1838 (expand_deps): If we aren't doing second expansion, replace % with
1839 the stem for static pattern rules. Call the new function.
1840 * filedef.h (parse_prereqs): Declare a prototype.
1841 * implicit.c (pattern_search): Initialize the new staticpattern
1843 * main.c (second_expansion): Declare a global variable to remember
1844 if the special target has been seen. Initialize the new
1845 staticpattern field for prerequisites.
1846 * make.h: Extern for second_expansion.
1847 * misc.c (free_dep_chain): New function: frees a struct dep list.
1848 * read.c (read_all_makefiles): Initialize the staticpattern field.
1849 (eval_makefile): Ditto.
1850 (record_files): Check for the .SECONDEXPANSION target and set
1851 second_expansion global if it's found.
1852 Use the new free_dep_chain() instead of doing it by hand.
1853 Set the staticpattern field for prereqs of static pattern targets.
1855 2005-10-16 Paul D. Smith <psmith@gnu.org>
1857 * main.c (main): Set CURDIR to be a file variable instead of a
1858 default, so that values of CURDIR inherited from the environment
1859 won't override the make value.
1861 2005-09-26 Paul D. Smith <psmith@gnu.org>
1863 * job.c (construct_command_argv_internal): If the line is empty
1864 remember to free the temporary argv strings.
1867 2005-09-16 Paul D. Smith <psmith@gnu.org>
1869 * job.c (start_job_command): The noerror flag is a boolean (single
1870 bit); set it appropriately.
1871 Reported by Mark Eichin <eichin@metacarta.com>
1873 2005-08-29 Paul D. Smith <psmith@gnu.org>
1875 * function.c (func_error): On Windows, output from $(info ...)
1876 seems to come in the wrong order. Try to force it with fflush().
1878 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1880 * read.c (record_files): Move code that sets stem for static
1881 pattern rules out of the if (!two_colon) condition so it is
1882 also executed for two-colon rules. Fixes Savannah bug #13881.
1884 2005-08-08 Paul D. Smith <psmith@gnu.org>
1886 * make.h: Don't test that __STDC__ is non-0. Some compilers
1887 (Windows for example) set it to 0 to denote "ISO C + extensions".
1890 2005-08-07 Paul D. Smith <psmith@gnu.org>
1892 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1893 conditional (slightly different version of a fix from Eli).
1895 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1896 If make is running in parallel without -k and two jobs die in a
1897 row, but not too close to each other, then make will quit without
1898 waiting for the rest of the jobs to die.
1900 * main.c (die): Don't reset err before calling reap_children() the
1901 second time: we still want it to be in the error condition.
1902 * job.c (reap_children): Use a static variable, rather than err,
1903 to control whether or not the error message should be printed.
1905 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1907 * w32/subproc/sub_proc.c: Include signal.h.
1908 (process_pipe_io, process_file_io): Pass a pointer to a local
1909 DWORD variable to GetExitCodeProcess. If the exit code is
1910 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1912 * job.c [WINDOWS32]: Include windows.h.
1913 (main_thread) [WINDOWS32]: New global variable.
1914 (reap_children) [WINDOWS32]: Get the handle for the main thread
1915 and store it in main_thread.
1917 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1918 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1919 doing anything else. When we are done, close the main thread
1920 handle and exit with status 130.
1922 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1924 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1927 * main.c (find_and_set_default_shell): If found a DOSish shell,
1928 set sh_found and the value of default_shell, and report the
1929 findings in debug mode.
1931 * job.c (construct_command_argv_internal): Check unixy_shell, not
1932 no_default_sh_exe, to decide whether to use Unixy or DOSish
1935 * README.W32: Update with info about the MinGW build.
1937 * build_w32.bat: Support MinGW.
1939 * w32/subproc/build.bat: Likewise.
1941 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1942 printing DWORD args.
1944 * function.c (windows32_openpipe): Fix format strings for printing
1947 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1949 (start_job_command): Fix format string for printing the result of
1951 (start_job_command) [WINDOWS32]: Do not define.
1952 (exec_command): Fix format string for printing HANDLE args.
1954 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1955 to avoid compiler warnings.
1956 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1957 (Note: some of these fixes were submitted independently by J. Grant)
1959 2005-07-30 J. Grant <jg@jguk.org>
1961 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1962 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1963 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1965 2005-07-15 Paul Smith <psmith@gnu.org>
1967 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1968 we don't have a POSIX shell, then revert to the old
1969 backslash-newline behavior (where they are stripped).
1972 2005-07-08 Paul D. Smith <psmith@gnu.org>
1974 * config.h.W32.template: Reorder to match the standard config.h,
1975 for easier comparisons.
1976 From J. Grant <jg@jguk.org>
1978 * maintMakefile: Remove .dep_segment before overwriting it, in
1979 case it's not writable or noclobber is set.
1980 * expand.c (variable_expand_string): Cast result of pointer
1981 arithmetic to avoid a warning.
1982 * main.c (switches): Add full-fledged final initializer.
1984 2005-07-06 Paul D. Smith <psmith@gnu.org>
1986 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1987 * signame.c (strsignal): If we found _sys_siglist[] or
1988 __sys_siglist[] use those instead of sys_siglist[].
1989 From Albert Chin <china@thewrittenword.com>
1991 2005-07-04 Paul D. Smith <psmith@gnu.org>
1993 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1994 globfree(); set up to use the GNU versions.
1995 From Martin Zinser <zinser@zinser.no-ip.info>
1997 2005-07-03 Paul D. Smith <psmith@gnu.org>
1999 From J. Grant <jg@jguk.org>:

2005 * w32/subproc/build.bat: Ditto.
2007 2005-06-28 Paul D. Smith <psmith@gnu.org>
2009 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2010 declaration was checked but not present.
2012 2005-06-27 Paul D. Smith <psmith@gnu.org>
2014 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2015 to unsigned long. Fixes Savannah bug #13550.
2017 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2018 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2019 Fixes Savannah bug #13551.
2021 2005-06-26 Paul D. Smith <psmith@gnu.org>
2023 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2024 it if ANSI_STRING is not set.
2026 2005-06-25 Paul D. Smith <psmith@gnu.org>
2028 * read.c (eval): If no filenames are passed to any of the
2029 "include" variants, don't print an error.
2030 * doc/make.texi (Include): Document this.
2031 Fixes Savannah bug #1761.
2033 * job.c (construct_command_argv_internal): Sanitize handling of
2034 backslash/newline pairs according to POSIX: that is, keep the
2035 backslash-newline in the command script, but remove a following
2036 TAB character, if present. In the fast path, make sure that the
2037 behavior matches what the shell would do both inside and outside
2038 of quotes. In the slow path, quote the backslash and put a
2039 literal newline in the string.
2040 Fixes Savannah bug #1332.
2041 * doc/make.texi (Execution): Document the new behavior and give
2043 * NEWS: Make a note of the new behavior.
2045 * make.h [WINDOWS32]: #include <direct.h>.
2046 Fixes Savannah bug #13478.
2048 * remake.c (name_mtime): If the stat() of a file fails and the -L
2049 option was given and the file is a symlink, take the best mtime of
2050 the symlink we can get as the mtime of the file and don't fail.
2051 Fixes Savannah bug #13280.
2053 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2054 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2055 inside a variable reference. Make this function static as it's
2057 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2058 parsing an unexpanded line looking for semicolons.
2059 Fixes Savannah bug #1454.
2060 * misc.c (remove_comments): Move this to read.c and make it static
2061 as it's only used there. Call find_char_unquote() with new arg.
2062 * make.h: Remove prototypes for find_char_unquote() and
2063 remove_comments() since they're static now.
2065 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2066 its export flag and obtain its value. When we need to re-exec,
2067 increment the value and add it into the environment.
2068 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2069 * NEWS: Mention MAKE_RESTARTS.
2070 * main.c (always_make_set): New variable. Change the -B option to
2071 set this one instead.
2072 (main): When checking makefiles, only set always_make_flag if
2073 always_make_set is set AND the restarts flag is 0. When building
2074 normal targets, set it IFF always_make_set is set.
2075 (main): Avoid infinite recursion with -W, too: only set what-if
2076 files to NEW before we check makefiles if we've never restarted
2077 before. If we have restarted, set what-if files to NEW _after_ we
2079 Fixes Savannah bug #7566:
2081 2005-06-17 Paul D. Smith <psmith@gnu.org>
2083 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2084 in the prerequisites list.
2086 2005-06-12 Paul D. Smith <psmith@gnu.org>
2088 Fix Savannah bug # 1328.
2090 * configure.in: Check for atexit().
2091 * misc.c (close_stdout): Test stdout to see if writes to it have
2092 failed. If so, be sure to exit with a non-0 error code. Based on
2093 code found in gnulib.
2094 * make.h: Prototype.
2095 * main.c (main): Install close_stdout() with atexit().
2097 2005-06-10 Paul D. Smith <psmith@gnu.org>
2099 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2101 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2102 headers; make vmsWaitForChildren() static; extern vmsify().
2103 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2104 Don't create child_execute_job() here (it's in vmsjobs.c).
2105 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2107 2005-06-09 Paul D. Smith <psmith@gnu.org>
2109 * variable.c (push_new_variable_scope): File variables point
2110 directly to the global_setlist variable. So, inserting a new
2111 scope in front of that has no effect on those variables: they
2112 don't go through current_variable_set_list. If we're pushing a
2113 scope and the current scope is global, push it "the other way" so
2114 that the new setlist is in the global_setlist variable, and
2115 next points to a new setlist with the global variable set.
2116 (pop_variable_scope): Properly undo a push with the new
2118 Fixes Savannah bug #11913.
2120 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2122 * job.c (reap_children): Don't die of the command failed but
2123 the dontcare flag is set. Fixes Savannah bug #13216.
2125 * implicit.c (pattern_search): When creating a target from
2126 an implicit rule match, lookup pattern target and set precious
2127 flag in a newly created target. Fixes Savannah bug #13218.
2129 2005-05-13 Paul D. Smith <psmith@gnu.org>
2131 Implement "if... else if... endif" syntax.
2133 * read.c (eval): Push all checks for conditional words ("ifeq",
2134 "else", etc.) down into the conditional_line() function.
2135 (conditional_line): Rework to allow "else if..." clause. New
2136 return value -2 for lines which are not conditionals. The
2137 ignoring flag can now also be 2, which means "already parsed a
2138 true branch". If that value is seen no other branch of this
2139 conditional can be considered true. In the else parsing if there
2140 is extra text after the else, invoke conditional_line()
2141 recursively to see if it's another conditional. If not, it's an
2142 error. If so, raise the conditional value to this level instead
2143 of creating a new conditional nesting level. Special check for
2144 "else" and "endif", which aren't allowed on the "else" line.
2145 * doc/make.texi (Conditional Syntax): Document the new syntax.
2147 2005-05-09 Paul D. Smith <psmith@gnu.org>
2149 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2150 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2151 recurses to the w32 directory, even on non-Windows systems. Use
2152 the method suggested in the automake manual.
2153 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2154 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2156 2005-05-07 Paul D. Smith <psmith@gnu.org>
2158 * main.c (die): If we're dying with a fatal error (not that a
2159 command has failed), write back any leftover tokens before we go.
2161 * job.c (set_child_handler_action_flags): If there are jobs
2162 waiting for the load to go down, set an alarm to go off in 1
2163 second. This allows us to wake up from a potentially long-lasting
2164 read() and start a new job if the load has gone down. Turn it off
2166 (job_noop): Dummy signal handler function.
2167 (new_job): Invoke it with the new semantics.
2169 * docs/make.texi: Document secondary expansion. Various cleanups
2172 2005-05-03 Paul D. Smith <psmith@gnu.org>
2174 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2175 the targets which are to ultimately be made are called "goals";
2176 see the GNU make manual. Also, MAKECMDGOALS, etc.
2178 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2179 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2180 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2182 2005-05-02 Paul D. Smith <psmith@gnu.org>
2184 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2185 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2186 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2187 functions to vmsjobs.c. #include it into jobs.c.
2189 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2190 jobserver tokens. I found that this happens when an exported
2191 recursive variable contains a $(shell ...) function reference: in
2192 this situation we could "forget" to write back a token.
2194 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2195 we have. It's not reliable to depend on the number of children in
2196 our linked list so keep a separate count.
2197 (new_job): Check jobserver_tokens rather than children &&
2198 waiting_jobs. Increment jobserver_tokens when we get one.
2199 (free_child): If jobserver_tokens is 0, internal error. If it's
2200 >1, write a token back to the jobserver pipe (we don't write a
2201 token for the "free" job). Decrement jobserver_tokens.
2203 * main.c: Add variable master_job_slots.
2204 (main): Set it to hold the number of jobs requested if we're the
2205 master process, when using the jobserver.
2206 (die): Sanity checks: first test jobserver_tokens to make sure
2207 this process isn't holding any tokens we didn't write back.
2208 Second, if master_job_slots is set count the tokens left in the
2209 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2211 2005-04-24 Paul D. Smith <psmith@gnu.org>
2213 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2214 with -l# can lose jobserver tokens, because waiting jobs are not
2215 consulted properly when checking for the "free" token.
2217 * job.c (free_child): Count waiting_jobs as having tokens.
2218 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2219 handle jobs waiting for the load to drop.
2221 2005-04-23 Paul D. Smith <psmith@gnu.org>
2223 * main.c (main): Be careful to not core if a variable setting in
2224 the environment doesn't contain an '='. This is illegal but can
2225 happen in broken setups.
2226 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2228 2005-04-12 Paul D. Smith <psmith@gnu.org>
2230 The second expansion feature causes significant slowdown. Timing
2231 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2232 read the makefile before the feature, to 11+s to do the same
2233 operations after the feature. Additionally, memory usage
2234 increased drastically. To fix this I added some intelligence that
2235 avoids the overhead of the second expansion unless it's required.
2237 * dep.h: Add a new boolean field, need_2nd_expansion.
2239 * read.c (eval): When creating the struct dep for the target,
2240 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2241 (record_files): If there's a "%" in a static pattern rule, it gets
2242 converted to "$*" so set need_2nd_expansion to 1.
2244 * file.c (expand_deps): Rework to be more efficient. Only perform
2245 initialize_file_variables(), set_file_variables(), and
2246 variable_expand_for_file() if the need_2nd_expansion is set.
2248 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2249 (pattern_search): Ditto.
2250 * main.c (handle_non_switch_argument): Ditto.
2252 * read.c (read_all_makefiles): Ditto.
2253 (eval_makefile): Ditto.
2255 2005-04-07 Paul D. Smith <psmith@gnu.org>
2257 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2258 * variable.c (sync_Path_environment): Ditto.
2259 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2261 * main.c (main): Define the .FEATURES variable.
2262 * NEWS: Announce .FEATURES.
2263 * doc/make.texi (Special Variables): Document .FEATURES.
2265 * remake.c (check_dep): If a file is .PHONY, update it even if
2266 it's marked intermediate. Fixes Savannah bug #12331.
2268 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2270 * file.c (expand_deps): Factor out the second expansion and
2271 prerequisite line parsing logic from snap_deps().
2273 * file.c (snap_deps): Use expand_deps(). Expand and parse
2274 prerequisites of the .SUFFIXES special target first. Fixes
2275 Savannah bug #12320.
2277 2005-03-13 Paul D. Smith <psmith@gnu.org>
2279 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2282 2005-03-11 Paul D. Smith <psmith@gnu.org>
2284 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2285 available, not undefined (from Earnie Boyd).
2287 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2289 * implicit.c (pattern_search): Mark an intermediate target as
2290 precious if it happened to be a prerequisite of some (other)
2291 target. Fixes Savannah bug #12267.
2293 2005-03-09 Paul D. Smith <psmith@gnu.org>
2295 * read.c (eval_makefile): Add alloca(0).
2296 (eval_buffer): Ditto.
2298 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2300 * main.c (main): Use o_file instead of o_default when defining
2301 the .DEFAULT_TARGET special variable.
2302 * read.c (eval): Use define_variable_global() instead of
2303 define_variable() when setting new value for the .DEFAULT_TARGET
2304 special variable. Fixes Savannah bug #12266.
2306 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2308 * imlicit.c (pattern_search): Mark files for which an implicit
2309 rule has been found as targets. Fixes Savannah bug #12202.
2311 2005-03-04 Paul D. Smith <psmith@gnu.org>
2314 * doc/make.texi (Automatic Variables): Document $|.
2316 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2318 * read.c (record_files): Instead of substituting % with
2319 actual stem value in dependency list replace it with $*.
2320 This fixes stem triple expansion bug.
2322 * implicit.c (pattern_search): Copy stem to a separate
2323 buffer and make it a properly terminated string. Assign
2324 this buffer instead of STEM (which is not terminated) to
2325 f->stem. Instead of substituting % with actual stem value
2326 in dependency list replace it with $*. This fixes stem
2327 triple expansion bug.
2329 2005-03-01 Paul D. Smith <psmith@gnu.org>
2331 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2332 on Windows, as it takes a handle not a pid. Just exit.
2333 Fix from patch #3679, provided by Alessandro Vesely.
2335 * configure.in: Update check for sys_siglist[] from autoconf manual.
2336 * signame.c (strsignal): Update to use the new autoconf macro.
2338 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2340 * read.c (record_files): Add a check for the list of prerequisites
2341 of a static pattern rule being empty. Fixes Savannah bug #12180.
2343 2005-02-28 Paul D. Smith <psmith@gnu.org>
2345 * doc/make.texi (Text Functions): Update docs to allow the end
2346 ordinal for $(wordlist ...) to be 0.
2347 * function.c (func_wordlist): Fail if the start ordinal for
2348 $(wordlist ...) is <1. Matches documentation.
2349 Resolves Savannah support request #103195.
2351 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2352 previously we were stopping when !-q, exactly the opposite. This
2353 has been wrong since version 1.34, in 1994!
2354 (update_file): If we got an error don't break out to run more
2355 double-colon rules: just return immediately.
2356 Fixes Savannah bug #7144.
2358 2005-02-27 Paul D. Smith <psmith@gnu.org>
2360 * misc.c (end_of_token): Make argument const.
2361 * make.h: Update prototype.
2363 * function.c (abspath, func_realpath, func_abspath): Use
2364 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2365 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2366 * read.c (record_files): Ditto.
2367 * variable.c (do_variable_definition): Ditto.
2369 * function.c (func_error): Create a new function $(info ...) that
2370 simply prints the message to stdout with no extras.
2371 (function_table_init): Add new function to the table.
2372 * NEWS: Add $(info ...) reference.
2373 * doc/make.texi (Make Control Functions): Document it.
2375 New feature: if the system supports symbolic links, and the user
2376 provides the -L/--check-symlink-time flag, then use the latest
2377 mtime between the symlink(s) and the target file.
2379 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2380 readlink(). If both are available, define MAKE_SYMLINKS.
2381 * main.c: New variable: check_symlink_flag.
2382 (usage): Add a line for -L/--check-symlink-times to the help string.
2383 (switches): Add -L/--check-symlink-times command line argument.
2384 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2385 print a warning and disable it again.
2386 * make.h: Declare check_symlink_flag.
2387 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2388 if the file is a symlink then check each link in the chain and
2389 choose the NEWEST mtime we find as the mtime for the file. The
2390 newest mtime might be the file itself!
2391 * NEWS: Add information about this new feature.
2392 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2394 Avoid core dumps described in Savannah bug # 12124:
2396 * file.c: New variable snapped_deps remember whether we've run
2398 (snap_deps): Set it.
2399 * filedef.h: Extern it.
2400 * read.c (record_files): Check snapped_deps; if it's set then
2401 we're trying to eval a new target/prerequisite relationship from
2402 within a command script, which we don't support. Fatal.
2404 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2406 Implementation of the .DEFAULT_TARGET special variable.
2408 * read.c (eval): If necessary, update default_target_name when
2410 * read.c (record_files): Update default_target_file if
2411 default_target_name has changed.
2412 * main.c (default_target_name): Define.
2413 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2414 default_target_name is set use default_target_file as a root
2416 * filedef.h (default_target_name): Declare.
2417 * dep.h (free_dep_chain):
2418 * misc.c (free_dep_chain): Change to operate on struct nameseq
2419 and change name to free_ns_chain.
2420 * file.c (snap_deps): Update to use free_ns_chain.
2422 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2424 Implementation of the second expansion in explicit rules,
2425 static pattern rules and implicit rules.
2427 * read.c (eval): Refrain from chopping up rule's dependencies.
2428 Store them in a struct dep as a single dependency line. Remove
2429 the code that implements SySV-style automatic variables.
2431 * read.c (record_files): Adjust the code that handles static
2432 pattern rules to expand all percents instead of only the first
2433 one. Reverse the order in which dependencies are stored so that
2434 when the second expansion reverses them again they appear in
2435 the makefile order (with some exceptions, see comments in
2436 the code). Remove the code that implements SySV-style automatic
2439 * file.c (snap_deps): Implement the second expansion and chopping
2440 of dependency lines for explicit rules.
2442 * implicit.c (struct idep): Define an auxiliary data type to hold
2443 implicit rule's dependencies after stem substitution and
2446 * implicit.c (free_idep_chain): Implement.
2448 * implicit.c (get_next_word): Implement helper function for
2449 parsing implicit rule's dependency lines into words taking
2450 into account variable expansion requests. Used in the stem
2453 * implicit.c (pattern_search): Implement the second expansion
2454 for implicit rules. Also fixes bug #12091.
2456 * commands.h (set_file_variables): Declare.
2457 * commands.c (set_file_variables): Remove static specifier.
2459 * dep.h (free_dep_chain): Declare.
2460 * misc.c (free_dep_chain): Implement.
2462 * variable.h (variable_expand_for_file): Declare.
2463 * expand.c (variable_expand_for_file): Remove static specifier.
2465 * make.h (strip_whitespace): Declare.
2466 * function.c (strip_whitespace): Remove static specifier.
2468 2005-02-26 Paul D. Smith <psmith@gnu.org>
2470 * main.c (main): Check for ferror() when reading makefiles from stdin.
2471 Apparently some shells in Windows don't close pipes properly and
2474 2005-02-24 Jonathan Grant <jg@jguk.org>
2476 * configure.in: Add MinGW configuration options, and extra w32 code
2478 * Makefile.am: Add MinGW configuration options, and extra w32 code
2480 * main.c: Determine correct program string (after last \ without .exe).
2481 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2483 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2484 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2485 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2486 environment support.
2488 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2490 * function.c (func_shell): When initializing error_prefix, check
2491 that reading file name is not null. This fixes long-standing
2492 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2494 2005-02-09 Paul D. Smith <psmith@gnu.org>
2496 * maintMakefile: Update the CVS download URL to simplify them.
2497 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2498 downloading the .texi files from Savannah now.
2500 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2502 * main.c (handle_non_switch_argument): Only add variables to
2503 command_variables if they're not already there: duplicate settings
2504 waste space and can be confusing to read.
2506 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2507 this header is never included by non-WINDOWS32 code, and it
2508 requires <config.h> to define which isn't always included first.
2510 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2511 testing MINGW32 versions.
2513 * main.c (log_working_directory): flush stdout to be sure the WD
2514 change is printed before any stderr messages show up.
2516 2005-02-01 Paul D. Smith <psmith@gnu.org>
2518 * maintMakefile (po_repo): Update the GNU translation site URL.
2520 2004-12-01 Paul D. Smith <psmith@gnu.org>
2522 * main.c (main): Change char* env_shell to struct variable shell_var.
2523 * variable.c (target_environment): Use new shell_var.
2525 2004-11-30 Paul D. Smith <psmith@gnu.org>
2527 * configure.in: The old way we avoided creating build.sh from
2528 build.sh.in before build.sh.in exists doesn't work anymore; we
2529 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2530 the help!). This also keeps automake from complaining.
2531 * Makefile.am (README): Add a dummy target so automake won't
2532 complain that this file doesn't exist when we checkout from CVS.
2533 * maintMakefile (.dep_segment): Rewrite this rule since newer
2534 versions of automake don't provide DEP_FILES.
2536 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2538 Implementation of `realpath' and `abspath' built-in functions.
2540 * configure.in: Check for realpath.
2541 * function.c (abspath): Return an absolute file name that does
2542 not contain any `.' or `..' components, nor repeated `/'.
2543 * function.c (func_abspath): For each name call abspath.
2544 * function.c (func_realpath): For each name call realpath
2545 from libc or delegate to abspath if realpath is not available.
2546 * doc/make.texi (Functions for File Names): Document new functions.
2547 * doc/make.texi (Quick Reference): Ditto.
2549 2004-11-28 Paul D. Smith <psmith@gnu.org>
2551 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2552 arguments. Fixes bug #10252.
2554 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2556 * main.c (main): Set SHELL to v_noexport by default. Remember the
2557 original environment setting of SHELL in the env_shell variable.
2558 * main.h: Export new env_shell variable.
2559 * variable.c (target_environment): If we find a v_noexport
2560 variable for SHELL, add a SHELL variable with the env_shell value.
2561 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2562 * doc/make.texi (Variables/Recursion): Ditto.
2564 2004-11-28 Paul D. Smith <psmith@gnu.org>
2566 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2567 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2568 Patch by Alessandro Vesely.
2570 2004-11-12 Paul D. Smith <psmith@gnu.org>
2572 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2573 the command line if it's inside a string.
2574 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2576 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2578 * function.c (func_lastword): New function: return last word
2579 from the list of words.
2580 * doc/make.texi: Document $(lastword ). Fix broken links in
2581 Quick Reference section.
2583 2004-10-06 Paul D. Smith <psmith@gnu.org>
2585 Apply patch from Alessandro Vesely, provided with bug # 9748.
2586 Fix use of tmpnam() to work with Borland C.
2588 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2589 construction of a temporary filename, and call new function
2590 create_batch_filename().
2591 (create_batch_filename) [WINDOWS32]: New function to create a
2594 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2596 * read.c (record_target_var): Expand simple pattern-specific
2598 * variable.c (initialize_file_variables): Do not expand simple
2599 pattern-specific variable.
2601 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2603 * remake.c (update_file_1): When rebuilding makefiles inherit
2604 dontcare flag from a target that triggered update.
2606 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2608 * variable.c (initialize_file_variables): Mark pattern-specific
2609 variable as a per-target and copy export status.
2611 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2613 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2615 * implicit.c (pattern_search): When considering an implicit rule's
2616 prerequisite check that it is actually a target rather then
2617 just an entry in the file hashtable.
2619 2004-09-21 Paul D. Smith <psmith@gnu.org>
2621 * read.c (readstring): Fix some logic errors in backslash handling.
2622 (eval): Remove some unnecessary processing in buffer handling.
2623 (record_target_var): Assert that parse_variable_definition() succeeded.
2624 Reported by: Markus Mauhart <qwe123@chello.at>.
2626 * misc.c: Removed the sindex() function. All instances of this
2627 function were trivially replaceable by the standard strstr()
2628 function, and that function will always have better (or certainly
2629 no worse) performance than the very simple-minded algorithm
2630 sindex() used. This can matter with complex makefiles.
2631 * make.h: Remove the prototype for sindex().
2632 * function.c (subst_expand): Convert sindex() call to strstr().
2633 This means we no longer need to track the TLEN value so remove that.
2634 (func_findstring): Convert sindex() to strstr().
2635 * commands.c (chop_commands): Convert sindex() calls to strstr().
2636 Suggested by: Markus Mauhart <qwe123@chello.at>.
2638 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2639 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2640 If SHELL is set to CMD.EXE then assume it's batch-mode and
2641 non-unixy. I wrote the code differently from the patch, though,
2642 to make it safer. This also resolves bug #9174.
2644 2004-09-20 Paul D. Smith <psmith@gnu.org>
2646 * expand.c (variable_expand_string): Modify to invoke
2647 patsubst_expand() instead of subst_expand(); the latter didn't
2648 handle suffix patterns correctly.
2649 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2650 was used only from variable_expand_string() and is no longer used
2652 (func_subst): Ditto, on call to subst_expand().
2653 (patsubst_expand): Require the percent pointers to point to the
2654 character after the %, not to the % itself.
2655 * read.c (record_files): New call criteria for patsubst_expand().
2656 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2657 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2659 2004-09-19 Paul D. Smith <psmith@gnu.org>
2661 * function.c (subst_expand): Fix a check in by_word: look for a
2662 previous blank if we're beyond the beginning of the string, not
2663 the beginning of the word.
2664 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2666 2004-05-16 Paul D. Smith <psmith@gnu.org>
2668 * remake.c (update_goal_chain): Change the argument specifying
2669 whether we're rebuilding makefiles to be a global variable,
2670 REBUILDING_MAKEFILES.
2671 (complain): Extract the code that complains about no rules to make
2672 a target into a separate function.
2673 (update_file_1): If we tried to rebuild a file during the makefile
2674 rebuild phase and it was dontcare, then no message was printed.
2675 If we then try to build the same file during the normal build,
2676 print a message this time.
2677 (remake_file): Don't complain about un-remake-able files when
2678 we're rebuilding makefiles.
2680 2004-05-11 Paul D. Smith <psmith@gnu.org>
2682 * job.c (construct_command_argv_internal): OS/2 patches from
2683 Andreas Buening <andreas.buening@nexgo.de>.
2685 2004-05-10 Paul D. Smith <psmith@gnu.org>
2687 * remake.c (update_file): Don't walk the double-colon chain unless
2688 this is a double-colon rule. Fix suggested by Boris Kolpackov
2689 <boris@kolpackov.net>.
2691 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2692 * readme.vms: New section describing OpenVMS support and issues.
2693 * default.c (default_variables): Add support for IA64.
2694 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2695 without some privilege aborts make with the error
2696 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2697 pressing Ctrl+Y and the input device is no terminal. The change
2698 catches this error and just continues.
2700 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2702 2004-04-25 Paul D. Smith <psmith@gnu.org>
2704 * commands.c (set_file_variables): Set $< properly in the face of
2705 order-only prerequisites.
2706 Patch from Boris Kolpackov <boris@kolpackov.net>
2708 2004-04-21 Bob Byrnes <byrnes@curl.com>
2710 * main.c (main): Notice failures to remake makefiles.
2712 2004-03-28 Paul D. Smith <psmith@gnu.org>
2714 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2716 * job.c: No default shell for RISC OS.
2717 (load_too_high): Hard-code the return to 1.
2718 (construct_command_argv_internal): No sh_chars or sh_cmds.
2719 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2721 2004-03-20 Paul D. Smith <psmith@gnu.org>
2723 * variable.c (do_variable_definition): Don't append from the
2724 global set if a previous non-appending target-specific variable
2725 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2728 * expand.c (reference_variable): Don't give up on variables with
2729 no value that have the target-specific append flag set: they might
2730 have a value after all. Reported by Oliver Schmidt
2731 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2732 <nikulin@dx1cmd.inp.nsk.su>.
2734 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2735 refer to absolute pathnames in directories that don't exist: some
2736 portion of the makefile could create those directories before we
2737 match the pattern. Fixes bugs #775 and #108.
2739 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2741 * main.c (main): Free makefile_mtimes if we have any.
2742 * README.W32.template: Update documentation for the current status
2743 of the MS-Windows port.
2744 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2745 environment variable is sometimes already defined which causes the
2747 * main.c (debug_signal_handler): Only define this function if
2748 SIGUSR1 is available.
2750 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2752 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2753 * README.OS2.template: Documentation updates.
2754 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2755 link line for safety.
2756 * maintMakefile (build.sh.in): Remove an extraneous ")".
2757 * job.c (child_execute_job): Close saved FDs.
2758 * job.c (exec_command) [OS/2]: exec_command(): If the command
2759 can't be exec'ed and if the shell is not Unix-sh, then try again
2760 with argv = { "cmd", "/c", ... }. Normally, this code is never
2761 reached for the cmd shell unless the command really doesn't exist.
2762 (construct_command_argv_internal) [OS/2]: The code for cmd
2763 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2764 The CMD builtin commands are case insensitive so use strcasecmp().
2766 2004-03-19 Paul D. Smith <psmith@gnu.org>
2768 * read.c (do_define): Re-order line counter increment so the count
2769 is accurate (we were losing one line per define). Reported by
2770 Dave Yost <Dave@Yost.com>.
2772 2004-03-06 Paul D. Smith <psmith@gnu.org>
2774 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2776 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2777 * misc.c (message,error,fatal): Ditto.
2778 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2779 * config.h.W32.template: Ditto.
2780 * config.h-vms.template: Ditto.
2781 * config.ami.template: Ditto.
2783 2004-03-04 Paul D. Smith <psmith@gnu.org>
2785 * README.template: Add a note about broken /bin/sh on SunOS
2786 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2788 * misc.c (message, error, fatal): Don't use "..." if we're using
2789 varargs. ansi2knr should handle this but it doesn't work: it
2790 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2791 done. On many systems (SunOS for example) va_dcl is a #define.
2792 So, force the use of the non-"..." version on pre-ANSI compilers.
2794 * maintMakefile (sign-dist): Create some rules to help automate
2795 the new GNU ftp upload method.
2797 2004-02-24 Paul D. Smith <psmith@gnu.org>
2799 * config.h.W32.template: Add HAVE_STDARG_H
2800 * config.h-vms.template: Ditto.
2801 * config.ami.template: Ditto.
2803 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2805 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2806 * build_w32.bat: Remove extra "+".
2808 2004-02-23 Paul D. Smith <psmith@gnu.org>
2810 * make.h: Create an UNUSED macro to mark unused parameters.
2811 * (many): Clean up warnings by applying UNUSED, fixing
2812 signed/unsigned incompatibilities, etc.
2814 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2816 * filedef.h: Name the command_state enumeration.
2817 * file.c (set_command_state): Use the enumeration in the function
2820 * configure.in: Explicitly set SET_MAKE to empty, to disable
2821 MAKE=make even when no make already exists. Fix bug #3823.
2823 2004-02-22 Paul D. Smith <psmith@gnu.org>
2825 * maintMakefile: Perl script to clean up all non-CVS files. Use
2826 it on all the subdirectories for the cvs-clean target.
2828 * main.c (decode_switches): Require non-empty strings for all our
2829 string command-line options. Fixes Debian bug # 164165.
2831 * configure.in: Check for stdarg.h and varargs.h.
2832 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2833 for printing messages.
2834 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2839 A number of patches for OS/2 support from Andreas Buening
2840 <andreas.buening@nexgo.de>:
2842 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2843 disable the SIGCHLD handler.
2844 (reap_children) [OS/2]: Remove special handling of job_rfd.
2845 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2846 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2847 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2848 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2849 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2852 2004-02-21 Paul D. Smith <psmith@gnu.org>
2854 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2855 <mail@kristov.de> reports that if process_begin() fails we don't
2856 handle the error condition correctly in all cases.
2857 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2858 to have a newline on the message.
2860 * job.c (construct_command_argv_internal): Add "test" to UNIX
2861 sh_cmds[]. Fixes Savannah bug # 7606.
2863 2004-02-04 Paul D. Smith <psmith@gnu.org>
2865 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2866 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2867 Hartmut Becker <Hartmut.Becker@hp.com>.
2869 2004-01-21 Paul D. Smith <psmith@gnu.org>
2871 * job.c (load_too_high): Implement an algorithm to control the
2872 "thundering herd" problem when using -l to control job creation
2873 via the load average. The system only recomputes the load once a
2874 second but we can start many jobs in a second. To solve this we
2875 keep track of the number of jobs started in the last second and
2876 apply a weight to try to guess what a correct load would be.
2877 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2878 Also fixes bug #4693.
2879 (reap_children): Decrease the job count for this second.
2880 (start_job_command): Increase the job count for this second.
2882 * read.c (conditional_line): Expand the text after ifn?def before
2883 checking to see if it's a single word. Fixes bug #7257.
2885 2004-01-09 Paul D. Smith <psmith@gnu.org>
2887 * file.c (print_file): Recurse to print all targets in
2888 double-colon rules. Fixes bug #4518, reported (with patch) by
2889 Andrew Chatham <chatham@google.com>.
2891 2004-01-07 Paul D. Smith <psmith@gnu.org>
2893 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2894 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2895 AC_FUNC_SETVBUF_REVERSED.
2897 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2898 (MAKE Variable): Fix Savannah bug #4898.
2900 * job.c (construct_command_argv_internal): Add "!" to the list of
2901 shell escape chars. POSIX sh allows it to appear before a
2902 command, to negate the exit code. Fixes bug #6404.
2904 * implicit.c (pattern_search): When matching an implicit rule,
2905 remember which dependencies have the ignore_mtime flag set.
2906 Original fix provided in Savannah patch #2349, by Benoit
2907 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2909 2003-11-22 Paul D. Smith <psmith@gnu.org>
2911 * README.W32.template (Outputs): Clarification on -j with
2912 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2915 2003-11-02 Paul D. Smith <psmith@gnu.org>
2917 * function.c (func_if): Strip all the trailing whitespace from the
2918 condition, then don't expand it. Fixed bug # 5798.
2920 * expand.c (recursively_expand_for_file): If we're expanding a
2921 variable with no file context, then use the variable's context.
2924 2003-10-21 Paul D. Smith <psmith@gnu.org>
2926 * main.c (log_working_directory): Add newlines to printf()s.
2928 * README.cvs: Add a note to ignore warnings during autoreconf.
2930 * maintMakefile (po_repo): Set a new URL for PO file updates.
2931 (get-config/config.guess get-config/config.sub): Get these files
2932 from the Savannah config project instead of ftp.gnu.org.
2934 2003-10-05 Paul Eggert <eggert@twinsun.com>
2936 * main.c (main): Avoid potential subscript error if environ has
2939 2003-08-22 Paul D. Smith <psmith@gnu.org>
2941 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2942 systems which don't yet implement the C89 standard :-/.
2944 2003-07-18 Paul D. Smith <psmith@gnu.org>
2946 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2947 [WINDOWS32]: Initialize hash.
2949 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2951 * dir.c (read_dirstream): Provide a workaround for broken versions of
2952 the MinGW dirent structure.
2954 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2956 * w32/include/dirent.h: Add __MINGW32__ filter.
2958 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2960 * make.h: Add global declaration of *make_host.
2961 * main.c (print_usage): Remove local declaration of *make_host.
2962 (print_version): Display "This program built for ..." after Copyright
2965 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2967 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2968 execution of "makeinfo --html make.texi".
2970 2003-04-30 Paul D. Smith <psmith@gnu.org>
2972 * build.template: Make some changes to maybe allow this script to
2973 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2975 * README.OS2.template: New file for OS/2 support. Original
2976 contributed by Andreas Buening.
2977 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2980 2003-04-19 Paul D. Smith <psmith@gnu.org>
2982 Fix bug #1405: allow a target to match multiple pattern-specific
2985 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2986 variable.c, where they've always belonged.
2987 * rule.h: Move the prototypes and struct pattern_var as well.
2988 * variable.c (initialize_file_variables): Invoke
2989 lookup_pattern_var() in a loop, until no more matches are found.
2990 If a match is found, create a new variable set for the target's
2991 pattern variables. Then merge the contents of each matching
2992 pattern variable set into the target's pattern variable set.
2993 (lookup_pattern_var): Change this function to be usable
2994 in a loop. It takes a starting position: if NULL, start at the
2995 beginning; if non-NULL, start with the pattern variable after that
2996 position, and return the next matching pattern.
2997 (create_pattern_var): Create a unique instance of
2998 pattern-specific variables for every definition in the makefile.
2999 Don't combine the same pattern together. This allows us to
3000 process the variable handling properly even when the same pattern
3001 is used multiple times.
3002 (parse_variable_definition): New function: break out the parsing
3003 of a variable definition line from try_variable_definition.
3004 (try_variable_definition): Call parse_variable_definition to
3006 (print_variable_data_base): Print out pattern-specific variables.
3007 * variable.h (struct variable): Remember when a variable is
3008 conditional. Also remember its flavor.
3009 (struct pattern_var): Instead of keeping a variable set, we just
3010 keep a single variable for each pattern.
3011 * read.c (record_target_var): Each pattern variable contains only a
3012 single variable, not a set, so create it properly.
3013 * doc/make.texi (Pattern-specific): Document the new behavior.
3015 2003-04-17 Paul D. Smith <psmith@gnu.org>
3017 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3018 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3019 file/directory naming rules for VMS so I can't tell whether this
3022 2003-04-09 Paul D. Smith <psmith@gnu.org>
3024 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3025 DOS-style pathnames: backslash separators and drive specifiers.
3027 2003-03-28 Paul D. Smith <psmith@gnu.org>
3029 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3030 the intermediate flag on all targets. Fixes bug #2515.
3032 2003-03-24 Paul D. Smith <psmith@gnu.org>
3034 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3035 Upgrade to autoconf 2.57 and automake 1.7.3.
3037 * job.c: More OS/2 changes from Andreas Buening.
3039 * file.c (print_file): Fix variable initialization.
3042 * remake.c (notice_finished_file):
3044 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3045 some calls (like readdir()) return NULL in valid situations
3046 without resetting errno. Fixes bug #2846.
3048 2003-02-25 Paul D. Smith <psmith@gnu.org>
3050 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3052 * job.c (_is_unixy_shell) [OS/2]: New function.
3053 Set default shell to /bin/sh.
3054 (reap_children): Close the job_rfd pipe here since we don't use a
3056 (set_child_handler_action_flags): define this to empty on OS/2.
3057 (start_job_command): Close the jobserver pipe and use
3058 child_execute_job() instead of fork/exec.
3059 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3060 rather than exec'ing, then reconfigure stdin/stdout.
3061 (exec_command): Rewrite to use spawn instead of exec. Return the
3064 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3065 in DOS. Handle the TEMP environment variable as in DOS. Don't
3066 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3067 use -j in DOS mode. Use child_execute_job() instead of
3070 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3073 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3074 prototypes that return values.
3076 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3078 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3079 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3081 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3084 2003-02-24 Paul D. Smith <psmith@gnu.org>
3086 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3087 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3088 (child_execute_job) [VMS]: Handle error status properly.
3089 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3091 * function.c (func_shell): Use EINTRLOOP() while reading from the
3092 subshell pipe (Fixes bug #2502).
3093 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3095 * main.c (main): Ditto.
3097 2003-01-30 Paul D. Smith <psmith@gnu.org>
3099 * read.c (eval): eval() was not fully reentrant, because the
3100 collapsed buffer was static. Change it to be an automatic
3101 variable so that eval() can be invoked recursively.
3103 (eval): Apply patch # 1022: fix memory reference error on long
3104 target-specific variable lines.
3105 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3107 * function.c (check_numeric): Combine the is_numeric() function
3108 into this function, since it's only called from one place.
3109 Constify this function. Have it print the incorrect string in the
3110 error message. Fixes bug #2407.
3111 (strip_whitespace): Constify.
3112 (func_if): Constify.
3113 * expand.c (expand_argument): Constify.

3117 Fix bug # 2169, also reported by other people on various systems.
3119 * make.h: Some systems, such as Solaris and PTX, do not fully
3120 implement POSIX-compliant SA_RESTART functionality; important
3121 system calls like stat() and readdir() can still fail with EINTR
3122 even if SA_RESTART has been set on the signal handler. So,
3123 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3124 EINTR for system calls which return -1 or 0 (NULL), respectively,
3126 Also, remove the old atomic_stat()/atomic_readdir() and
3127 HAVE_BROKEN_RESTART handling.
3129 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3131 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3132 * remake.c (touch_file): Ditto.
3134 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3135 * read.c (construct_include_path): Ditto.
3136 * remake.c (name_mtime): Ditto.
3137 * vpath.c (selective_vpath_search): Ditto.
3138 * dir.c (find_directory): Ditto.
3139 (local_stat): Ditto.
3140 (find_directory): Use ENULLLOOP() to wrap opendir().
3141 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3143 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3144 atomic_readdir() handling.
3146 2003-01-22 Paul D. Smith <psmith@gnu.org>
3148 * function.c (func_call): Fix Bug #1744. If we're inside a
3149 recursive invocation of $(call ...), mask any of the outer
3150 invocation's arguments that aren't used by this one, so that this
3151 invocation doesn't "inherit" them accidentally.
3153 2002-12-05 Paul D. Smith <psmith@gnu.org>
3155 * function.c (subst_expand): Valery Khamenia reported a
3156 pathological performance hit when doing substitutions on very
3157 large values with lots of words: turns out we were invoking
3158 strlen() a ridiculous number of times. Instead of having each
3159 call to sindex() call strlen() again, keep track of how much of
3160 the text we've seen and pass the length to sindex().
3162 2002-11-19 Paul D. Smith <psmith@gnu.org>
3164 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3167 2002-11-16 Paul D. Smith <psmith@gnu.org>
3169 * NMakefile.template (OBJS): Add hash.c object file.
3170 * SMakefile.template (srcs): Ditto.
3171 * Makefile.ami (objs): Ditto.
3172 * build_w32.bat: Ditto.
3174 * Makefile.DOS.template: Remove extra dependencies.
3176 2002-10-25 Paul D. Smith <psmith@gnu.org>
3178 * expand.c (install_variable_buffer): New function. Install a new
3179 variable_buffer context and return the previous one.
3180 (restore_variable_buffer): New function. Free the current
3181 variable_buffer context and put a previously saved one back.
3182 * variable.h: Prototypes for {install,restore}_variable_buffer.
3183 * function.c (func_eval): Push a new variable_buffer context
3184 before we eval, then restore the old one when we're done.
3187 * read.c (install_conditionals): New function. Install a new
3188 conditional context and return the previous one.
3189 (restore_conditionals): New function. Free the current
3190 conditional context and put a previously saved one back.
3191 (eval): Use the {install,restore}_conditionals for "include"
3193 (eval_buffer): Use {install,restore}_conditionals to preserve the
3194 present conditional state before we evaluate the buffer.
3197 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3199 (Recursion): Add a variable index entry for CURDIR.
3201 * README.cvs: Update to appropriate versions.
3202 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3203 don't need to copy loadavg.c: automake is smart enough to create
3204 it for me. Still have a bug in automake related to ansi2knr tho.
3206 2002-10-14 Paul D. Smith <psmith@gnu.org>
3208 * remake.c (notice_finished_file): Only touch targets if they have
3209 at least one command (as per POSIX). Resolve Bug #1418.
3211 * *.c: Convert to using ANSI C-style function definitions.
3212 * Makefile.am: Enable the ansi2knr feature of automake.
3213 * configure.in: ditto.
3215 2002-10-13 Paul D. Smith <psmith@gnu.org>
3217 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3218 for automatic variable values like $^, etc. In the case of very
3219 large lists of prerequisites this causes problems. Instead reuse
3220 a static buffer (resizeable) for each variable.
3222 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3223 target-specific variable definitions. Check for it and set an
3225 (record_target_var): Set the export field to v_export if the
3226 "exported" flag is set.
3227 * doc/make.texi (Target-specific): Document the ability to use
3230 * doc/make.texi: Change the name of the section on automatic
3231 variables from "Automatic" to "Automatic Variables". Added text
3232 clarifying the scope of automatic variables.
3234 2002-10-04 Paul D. Smith <psmith@gnu.org>
3236 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3238 (record_files): Ditto.
3240 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3241 the search for the '=' to only within the enclosing parens.
3243 2002-10-03 Paul D. Smith <psmith@gnu.org>
3245 Version 3.80 released.
3247 * dir.c: Change hash functions to use K&R function definition style.
3248 * function.c: Ditto.
3250 * variable.c: Ditto.
3252 Update to automake 1.7.
3254 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3255 (pdf): Remove this target as automake now provides one.
3257 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3259 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3261 * makefile.com: Updates for GNU make 3.80.
3262 * makefile.vms: Ditto.
3264 2002-09-23 Paul D. Smith <psmith@gnu.org>
3266 * read.c (enum make_word_type): Remove w_comment.
3267 (get_next_mword): Don't treat comment characters as special; where
3268 this function is used we will never see a comment (it's stripped
3269 before we get here) and treating comments specially means that
3270 targets like "foo\#bar" aren't handled properly.
3272 2002-09-18 Paul D. Smith <psmith@gnu.org>
3274 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3276 * read.c (eval): Expansion of arguments to export/unexport was
3277 ignoring all arguments after the first one. Change the algorithm
3278 to expand the whole line once, then parse the results.
3280 2002-09-17 Paul D. Smith <psmith@gnu.org>
3282 Fix Bug #940 (plus another bug I found while looking at this):
3284 * read.c (record_target_var): enter_file() will add a new entry if
3285 it's a double-colon target: we don't want to do that in this
3286 situation. Invoke lookup_file() and only enter_file() if it does
3287 not already exist. If the file we get back is a double-colon then
3288 add this variable to the "root" double-colon target.
3290 * variable.c (initialize_file_variables): If this file is a
3291 double-colon target but is not the "root" target, then initialize
3292 the root and make the root's variable list the parent of our
3295 2002-09-13 Paul D. Smith <psmith@gnu.org>
3297 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3299 * hash.c (round_up_2): Get rid of a warning.
3301 2002-09-12 Paul D. Smith <psmith@gnu.org>
3303 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3304 so it doesn't complain about getloadavg.c.
3306 * commands.c (set_file_variables): Make sure we always alloca() at
3307 least 1 character for the value of $? (for '\0').
3309 2002-09-11 Paul D. Smith <psmith@gnu.org>
3311 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3312 macro to use RESULT instead of the incorrect _RESULT_.
3314 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3315 and atomic_readdir(). We need to #include dirent.h to get this to
3317 * misc.c (atomic_readdir): Fix typos.
3319 2002-09-10 Paul D. Smith <psmith@gnu.org>
3321 * read.c (eval): Expand variable lists given to export and
3322 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3323 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3325 * doc/make.texi (Variables/Recursion): Document this.
3326 (Conditional Syntax): And here.
3328 2002-09-09 Paul D. Smith <psmith@gnu.org>
3330 * configure.in: Check for memmove().
3332 2002-09-07 Paul D. Smith <psmith@gnu.org>
3334 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3335 Michael Sterrett <msterret@coat.com> reports that while it has
3336 SA_RESTART, it does not work properly.
3338 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3339 that invokes stat() and loops to do it again if it returns EINTR.
3340 (atomic_readdir): Ditto, with readdir().
3342 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3343 and readdir() to atomic_stat() and atomic_readdir().
3345 2002-09-04 Paul D. Smith <psmith@gnu.org>
3347 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3348 reports that GNU make sometimes doesn't recognize that targets can
3349 be made, when directories can be created as prerequisites. He
3350 reports that changing the order of predicates in the DEP->changed
3351 flag test so that lookup_file() is always performed, solves this
3354 2002-08-08 Paul D. Smith <psmith@gnu.org>
3356 * configure.in: Require a newer version of gettext.
3358 * misc.c (perror_with_name): Translate the format string (for
3359 right-to-left language support).
3360 (pfatal_with_name): Ditto.
3362 * main.c: Create a static array of strings to store the usage
3363 text. This is done to facilitate translations.
3364 (struct command_switch): Remove argdesc and description fields.
3365 (switches): Remove values for obsolete fields.
3366 (print_usage): Print each element of the usage array.
3368 * hash.c: Change function definitions to be K&R style.
3370 2002-08-02 Paul D. Smith <psmith@gnu.org>
3372 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3373 this one because it's too hard to get right. We'll look at it for
3375 * main.c (main): Don't create the .TARGETS variable.
3376 * variable.c (handle_special_var): Don't handle .TARGETS.
3378 2002-08-01 Paul D. Smith <psmith@gnu.org>

3383 (always_make_flag): New flag.
3384 * make.h: Extern always_make_flag.
3385 * remake.c (update_file_1): Check always_make_flag; if it's set we
3386 will always rebuild any target we can, even if none of its
3387 prerequisites are newer.
3390 * doc/make.texi (Shell Function): Make it clear that make
3391 variables marked as "export" are not passed to instances of the
3394 Add new introspection variable .VARIABLES and .TARGETS.
3396 * variable.c (handle_special_var): New function. If the variable
3397 reference passed in is "special" (.VARIABLES or .TARGETS),
3398 calculate the new value if necessary. .VARIABLES is handled here:
3399 walk through the hash of defined variables and construct a value
3400 which is a list of the names. .TARGETS is handled by
3401 build_target_list().
3402 (lookup_variable): Invoke handle_special_var().
3403 * file.c (build_target_list): Walk through the hask of known files
3404 and construct a list of the names of all the ones marked as
3406 * main.c (main): Initialize them to empty (and as simple variables).
3407 * doc/make.texi (Special Variables): Document them.
3408 * NEWS: Mention them.
3410 * variable.h (struct variable): Add a new flag "exportable" which
3411 is true if the variable name is valid for export.
3412 * variable.c (define_variable_in_set): Set "exportable" when a new
3413 variable is defined.
3414 (target_environment): Use the "exportable" flag instead of
3415 re-checking the name here... an efficiency improvement.
3417 2002-07-31 Paul D. Smith <psmith@gnu.org>
3419 * config.h-vms.template: Updates to build on VMS. Thanks to
3420 Brian_Benning@aksteel.com for helping verify the build.
3421 * makefile.com: Build the new hash.c file.
3422 * hash.h: Use strcpmi(), not stricmp(), in the
3423 HAVE_CASE_INSENSITIVE_FS case.
3425 2002-07-30 Paul D. Smith <psmith@gnu.org>
3427 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3428 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3429 Reported by <Brian_Benning@aksteel.com>.

3433 * variable.c (pop_variable_scope): Remove variable made unused by
3434 new hash infrastructure.
3435 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3436 comparisons as well as name comparisons.

3438 * file.c (lookup_file): Remove variables made unused by new hash
3440 * dir.c (directory_contents_hash_2): Missing return of hash value.
3441 (dir_contents_file_exists_p): Remove variables made unused by new
3442 hash infrastructure.
3445 Installed Greg McGary's integration of the hash functions from the
3446 GNU id-utils package:
3448 2002-07-10 Greg McGary <greg@mcgary.org>
3450 * scripts/functions/filter-out: Add literals to to the
3451 pattern space in order to add complexity, and trigger
3452 use of an internal hash table. Fix documentation strings.
3453 * scripts/targets/INTERMEDIATE: Reverse order of files
3454 passed to expected `rm' command.
3456 2002-07-10 Greg McGary <greg@mcgary.org>

3550 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3551 prerequisite list. A real SysV make will expand the entire
3552 prerequisites list _twice_: we don't do that as it's a big
3553 backward-compatibility problem. We only replace those specific
3556 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3557 references left in the list of prerequisites. Check for .POSIX as
3558 we record targets, so we can disable non-POSIX behavior while
3559 reading makefiles as well as running them.
3560 (eval): Check the prerequisite list to see if we have anything
3561 that looks like a SysV prerequisite variable reference.
3563 2002-07-09 Paul D. Smith <psmith@gnu.org>
3565 * doc/make.texi (Prerequisite Types): Add a new section describing
3566 order-only prerequisites.
3568 * read.c (uniquize_deps): If we have the same file as both a
3569 normal and order-only prereq, get rid of the order-only prereq,
3570 since the normal one supersedes it.
3572 2002-07-08 Paul D. Smith <psmith@gnu.org>
3574 * AUTHORS: Added Greg McGary to the AUTHORS file.
3575 * NEWS: Blurbed order-only prerequisites.
3576 * file.c (print_file): Show order-only deps properly when printing
3579 * maintMakefile: Add "update" targets for wget'ing the latest
3580 versions of various external files. Taken from Makefile.maint in
3583 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3584 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3586 2002-07-07 Paul D. Smith <psmith@gnu.org>
3588 * po/*.po: Remove. We'll use wget to retrieve them at release
3591 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3592 rather than a shell you get an exception. Make sure we look up
3593 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3595 * remake.c (notice_finished_file): Fix handling of -t flag.
3596 Patch provided by Henning Makholm <henning@makholm.net>.
3598 * implicit.c (pattern_search): Some systems apparently run short
3599 of stack space, and using alloca() in this function caused an
3600 overrun. I modified it to use xmalloc() on the two variables
3601 which seemed like they might get large. Fixes Bug #476.
3603 * main.c (print_version): Update copyright notice to conform with
3605 (print_usage): Update help output.
3607 * function.c (func_eval): Create a new make function, $(eval
3608 ...). Expand the arguments, put them into a buffer, then invoke
3609 eval_buffer() on the resulting string.
3610 (func_quote): Create a new function, $(quote VARNAME). Inserts
3611 the value of the variable VARNAME without expanding it any
3614 * read.c (struct ebuffer): Change the linebuffer structure to an
3615 "eval buffer", which can be either a file or a buffer.
3616 (eval_makefile): Move the code in the old read_makefile() which
3617 located a makefile into here: create a struct ebuffer with that
3618 information. Have it invoke the new function eval() with that
3620 (eval_buffer): Create a new function that creates a struct ebuffer
3621 that holds a string buffer instead of a file. Have it invoke
3622 eval() with that ebuffer.
3623 (eval): New function that contains the guts of the old
3624 read_makefile() function: this function parses makefiles. Obtains
3625 data to parse from the provided ebuffer. Some modifications to
3626 make the flow of the function cleaner and clearer. Still could
3627 use some work here...
3628 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3629 contents of the define/endef variable from the ebuffer.
3630 (readstring): Read the next line from a string-style ebuffer.
3631 (readline): Read the next line from an ebuffer. If it's a string
3632 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3635 * dep.h (eval_buffer): Prototype eval_buffer();
3637 * variable.c (do_variable_definition): Make sure that all
3638 non-target-specific variables are registered in the global set.
3639 If we're invoked from an $(eval ...) we might be inside a $(call
3640 ...) or other function which has pushed a variable scope; we still
3641 want to define our variables from evaluated makefile code in the
3644 2002-07-03 Greg McGary <greg@mcgary.org>
3646 * dep.h (struct dep) [ignore_mtime]: New member.
3647 [changed]: convert to a bitfield.
3648 * implicit.c (pattern_search): Zero ignore_mtime.
3649 * main.c (main, handle_non_switch_argument): Likewise.
3650 * rule.c (convert_suffix_rule): Likewise.
3651 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3652 (read_makefile): Parse '|' in prerequisite list.
3653 (uniquize_deps): Consider ignore_mtime when comparing deps.
3654 * remake.c (update_file_1, check_dep): Don't force remake for
3655 dependencies that have d->ignore_mtime.
3656 * commands.c (FILE_LIST_SEPARATOR): New constant.
3657 (set_file_variables): Don't include a
3658 prerequisite in $+, $^ or $? if d->ignore_mtime.
3661 2002-06-18 Paul D. Smith <psmith@gnu.org>
3663 * make.texinfo: Updates for next revision. New date/rev/etc.
3664 Recreate all Info menus. Change license on the manual to the GNU
3665 Free Documentation License. A number of typos.
3666 (Variables Simplify): Don't use "-" before it's defined.
3667 (Automatic Prerequisites): Rewrite the target example to work
3668 properly if the compile fails. Remove incorrect comments about
3669 how "set -e" behaves.
3670 (Text Functions): Move the "word", "wordlist", "words", and
3671 "firstword" functions here, from "File Name Functions".
3672 * make-stds.texi: Update from latest GNU version.
3673 * fdl.texi: (created) Import the latest GNU version.
3675 2002-06-06 Paul D. Smith <psmith@gnu.org>
3677 * variable.c (do_variable_definition): New function: extract the
3678 part of try_variable_definition() that actually sets the value
3679 into a separate function.
3680 (try_variable_definition): Call do_variable_definition() after
3681 parsing the variable definition string.
3682 (define_variable_in_set): Make the name argument const.
3684 * variable.h (enum variable_flavor): Make public.
3685 (do_variable_definition): Create prototype.
3687 * read.c (read_all_makefiles): Create a new built-in variable,
3689 (read_makefile): Add each makefile read in to this variable value.
3691 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3693 * Makefile.DOS.template: Tweak according to changes in the
3694 distribution. Add back the dependencies of *.o files.
3696 * configh.dos.template: Synchronize with config.h.in.
3698 2002-05-09 Paul D. Smith <psmith@gnu.org>
3700 * file.c (file_timestamp_now): Use K&R function declaration.
3702 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3703 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3704 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3705 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3706 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3707 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3708 nlist.n_name is a pointer rather than an array.
3710 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3711 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3712 * configure.in: Use it instead of the old version.
3714 * main.c (main): Prefer setvbuf() to setlinebuf().
3716 2002-05-08 Paul D. Smith <psmith@gnu.org>
3718 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3719 (loadavg_LDADD): Ditto.
3721 2002-04-29 Paul D. Smith <psmith@gnu.org>
3723 * expand.c (recursively_expand_for_file): Rename
3724 recursively_expand() to recursively_expand_for_file() and provide
3725 an extra argument, struct file. If the argument is provided, set
3726 the variable scope to that of the file before expanding.
3727 * variable.h (recursively_expand): Make this a macro that invokes
3728 recursively_expand_for_file() with a NULL file pointer.
3729 * variable.c (target_environment): Call the renamed function and
3730 provide the current file context.
3731 Fixes Debian bug #144306.
3733 2002-04-28 Paul D. Smith <psmith@gnu.org>
3735 Allow $(call ...) user-defined variables to be self-referencing
3736 without throwing an error. Allows implementation of transitive
3737 closures, among other possibly useful things.
3738 Requested by: Philip Guenther <guenther@sendmail.com>
3740 * variable.h (struct variable): Add a new field: exp_count, and
3741 new macros to hold its size and maximum value.
3742 (warn_undefined): Make this a macro.
3743 * variable.c (define_variable_in_set): Initialize it.
3744 * expand.c (recursively_expand): If we detect recursive expansion
3745 of a variable, check the exp_count field. If it's greater than 0
3746 allow the recursion and decrement the count.
3747 (warn_undefined): Remove this (now a macro in variable.h).
3748 * function.c (func_call): Before we expand the user-defined
3749 function, modify its exp_count field to contain the maximum
3750 number of recursive calls we'll allow. After the call, reset it
3753 2002-04-21 Paul D. Smith <psmith@gnu.org>
3755 Modified to use latest autoconf (2.53), automake (1.6.1), and
3756 gettext (0.11.1). We're using gettext's new "external" support,
3757 to avoid including libintl source with GNU make.
3759 * README.cvs: New file. Explain how to build GNU make from CVS.
3761 * configure.in: Modify checking for the system glob library.
3762 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3763 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3764 etc. will manage it correctly). Set an automake conditional
3765 USE_LOCAL_GLOB to decide whether to compile the glob library.
3767 * getloadavg.c (main): Include make.h in the "TEST" program to
3770 * Makefile.am: Remove special rules for loadavg. Replace them
3771 with Automake capabilities for building extra programs.
3773 * signame.c: This file does nothing if the system provide
3774 strsignal(). If not, it implements strsignal(). If the system
3775 doesn't define sys_siglist, then we make our own; otherwise we use
3777 * signame.h: Removed.
3779 * main.c (main): No need to invoke signame_init(). Update copyright.
3781 * ABOUT-NLS: Removed.
3782 * gettext.c: Removed.
3783 * gettext.h: Get a simplified copy from the gettext package.
3785 * i18n/*.po: Moved to po/.
3788 * config/*: Created. Contains package configuration helper files.
3789 * config.guess, config.sub: Moved to config directory.
3791 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3792 Rework to use new-style autoconf features. Use the "external"
3793 mode for gettext. Make the build.sh config file conditional on
3794 whether build.sh.in exists, to avoid autoconf errors.
3795 * acinclude.m4: Removed almost all macros as being obsolete.
3796 Rewrote remaining macros to use AC_DEFINE.
3797 * acconfig.h: Removed.
3799 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3800 conditional to handle customs support. Remove special handling
3803 2002-04-20 Paul D. Smith <psmith@gnu.org>
3805 * function.c (func_call): Don't mark the argument variables $1,
3806 etc. as recursive. They've already been fully expanded so
3807 there's no need to do it again, and doing so strips escaped $'s.
3808 Reported by Sebastian Glita <glseba@yahoo.com>.
3810 * remake.c (notice_finished_file): Walk through double-colon
3811 entries via the prev field, not the next field!
3812 Reported by Greg McGary <greg@mcgary.org>.
3814 * main.c (main): If the user specifies -q and asks for a specific
3815 target which is a makefile, we got an assert. In that case it
3816 turns out we should continue normally instead.
3818 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3820 * i18n/he.po: Installed a new translation.
3822 2002-01-07 Paul D. Smith <psmith@gnu.org>
3824 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3826 2001-12-04 Paul D. Smith <psmith@gnu.org>
3828 * i18n/ja.po: Installed an updated translation.
3830 2001-09-06 Paul Eggert <eggert@twinsun.com>
3832 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3833 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3835 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3837 (main): Get rid of any avoidable limit on stack size.
3839 2001-09-04 Paul D. Smith <psmith@gnu.org>
3841 * i18n/da.po: Installed an updated translation.
3843 2001-08-03 Paul D. Smith <psmith@gnu.org>
3845 * i18n/fr.po: Installed an updated translation.
3846 Resolves Debian bug #106720.
3848 2001-06-13 Paul D. Smith <psmith@gnu.org>
3850 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3853 2001-06-11 Paul D. Smith <psmith@gnu.org>
3855 * i18n/ko.po: Installed a new translation.
3857 2001-05-06 Paul D. Smith <psmith@gnu.org>
3859 Modify the EINTR handling.
3861 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3862 the way in which we manage the file descriptor/signal handler race
3863 trap to be more efficient.
3865 2001-05-06 Paul Eggert <eggert@twinsun.com>
3867 Restart almost all system calls that are interrupted, instead
3868 of worrying about EINTR. The lone exception is the read() for
3871 * configure.in (HAVE_SA_RESTART): New macro.
3872 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3873 * main.c (main): Use SA_RESTART instead of the old,
3874 nonstandard SA_INTERRUPT.
3876 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3877 * main.c (bsd_signal): New function or macro,
3878 if the implementation doesn't supply it.
3879 (The bsd_signal function will be in POSIX 1003.1-200x.)
3880 (HANDLESIG): Remove.
3881 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3883 * make.h (EINTR_SET): Remove.
3884 (SA_RESTART): New macro.
3886 * arscan.c (ar_member_touch): Don't worry about EINTR.
3887 * function.c (func_shell): Likewise.
3888 * job.c (reap_children, free_child, new_job): Likewise.
3889 * main.c (main): Likewise.
3890 * remake.c (touch_file, name_mtime): Likewise.
3892 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3893 if fstat failed with errno!=EINTR, the error was ignored.
3895 * job.c (set_child_handler_action_flags): New function.
3896 (new_job): Use it to temporarily clear the SIGCHLD action flags
3897 while reading the token.
3899 2001-05-02 Paul D. Smith <psmith@gnu.org>
3901 * job.c (start_job_command): Don't add define/endef per-line flags
3902 to the top-level flags setting.
3904 2001-04-03 Paul D. Smith <psmith@gnu.org>
3906 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3907 bit on error, so check for odd return values, not non-0 return
3909 (VMS_get_member_info): Calculate the timezone differences correctly.
3910 Reported by John Fowler <jfowler@nyx.net>.
3913 2001-03-14 Paul D. Smith <psmith@gnu.org>
3915 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3916 value before invoking define_variable().
3917 Reported by John Fowler <jfowler@nyx.net>.
3919 2001-02-07 Paul D. Smith <psmith@gnu.org>
3921 * read.c (record_target_var): If we reset the variable due to a
3922 command-line variable setting overriding it, turn off the "append"
3925 2001-01-17 Paul D. Smith <psmith@gnu.org>
3927 * variable.c (lookup_variable) [VMS]: When getting values from the
3928 environment, allocate enough space for the _value_ plus escapes,
3929 not enough space for the name plus escapes :-/.
3930 Reported by John Fowler <jfowler@nyx.net>.
3932 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3933 warnings that make generates, so it doesn't look like an error.
3934 Reported by Karl Berry <karl@gnu.org>.
3937 Fix for PR/2020: Rework appended target-specific variables. I'm
3938 fairly confident this algorithm is finally correct.
3940 * expand.c (allocated_variable_append): Rewrite. Instead of
3941 expanding each appended variable then adding all the expanded
3942 strings together, we append all the unexpanded values going up
3943 through the variable set contexts, then expand the final result.
3944 This behaves just like non-target-specific appended variable
3945 values, while the old way didn't in various corner cases.
3946 (variable_append): New function: recursively append the unexpanded
3947 value of a variable, walking from the outermost variable scope to
3949 * variable.c (lookup_variable): Remove the code that looked up the
3950 variable set list if the found variable was "append". We don't
3952 (lookup_variable_in_set): Make this non-static so we can use it
3954 (try_variable_definition): Use lookup_variable_in_set() rather
3955 than faking out current_variable_set_list by hand (cleanup).
3956 * variable.h: Add a prototype for the now non-static
3957 lookup_variable_in_set().
3959 2000-11-17 Paul D. Smith <psmith@gnu.org>
3961 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3962 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3963 before throwing a fit.
3965 2000-11-17 Paul D. Smith <psmith@gnu.org>
3967 * read.c (readline): CRLF calculations had a hole, if you hit the
3968 buffer grow scenario just right. Reworked the algorithm to avoid
3969 the need for len or lastlen at all. Problem description with
3970 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3972 2000-10-24 Paul D. Smith <psmith@gnu.org>
3974 * gettext.c (SWAP): Declare this with the prototype, otherwise
3975 some systems don't work (non-32-bit? Reported for Cray T3E).
3976 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3978 2000-10-05 Paul D. Smith <psmith@gnu.org>
3980 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3981 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3983 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3985 2000-09-22 Paul D. Smith <psmith@gnu.org>
3987 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3988 parts of the real gettext.h here, and we expect to really include
3989 the real gettext.h later. If we keep this #define, it's ignored.
3991 2000-09-21 Paul D. Smith <psmith@gnu.org>
3993 * main.c (log_working_directory): Rework the text to use complete
3994 sentences, to make life simpler for the translators.
3996 2000-08-29 Paul D. Smith <psmith@gnu.org>
3998 * file.c (remove_intermediates): Print a debug message before we
3999 remove intermediate files, so the user (if she uses -d) knows
4002 2000-08-21 Paul D. Smith <psmith@gnu.org>
4004 * variable.c (try_variable_definition): Change how we handle
4005 target-specific append variable defns: instead of just setting the
4006 value, expand it as an append _but_ only within the current
4007 target's context. Otherwise we lose all but the last value if the
4008 variable is appended more than once within the current target
4009 context. Fixes PR/1831.
4011 2000-08-16 Paul D. Smith <psmith@gnu.org>
4013 * function.c (func_shell): Nul-terminate the buffer before
4014 printing an exec error message (just in case it's not!).
4015 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4017 2000-07-25 Paul D. Smith <psmith@gnu.org>
4019 * job.c (construct_command_argv_internal): Add "~" to the list of
4020 sh_chars[] which disallow optimizing out the shell call.
4022 2000-07-23 Paul Eggert <eggert@twinsun.com>
4024 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4025 supersedes --disable-nsec-timestamps.
4026 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4027 * README: Remove --disable-nsec-timestamps.
4029 * filedef.h (struct file.low_resolution_time): New member.
4030 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4031 * remake.c (update_file_1):
4032 Avoid spurious rebuilds due to low resolution time stamps,
4033 generalizing the earlier code that applied only to archive members.
4034 (f_mtime): Archive members always have low resolution time stamps.
4036 * configure.in: Remove --disable-nsec-timestamps, as this has
4037 been superseded by .LOW_RESOLUTION_TIME.
4039 2000-07-23 Paul Eggert <eggert@twinsun.com>
4041 * configure.in (enable_nsec_timestamps): Renamed from
4042 make_cv_nsec_timestamps, since enable/disable options
4043 shouldn't be cached.
4045 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4046 and Paul Eggert <eggert@twinsun.com>
4048 * file.c (file_timestamp_now):
4049 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4050 so that clock_gettime is not linked unless needed.
4052 * filedef.h (FILE_TIMESTAMP_HI_RES):
4053 Remove definition; "configure" now does this.
4055 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4056 to before high resolution file timestamp check,
4057 since that check now uses uintmax_t.
4058 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4059 high resolution file timestamps.
4060 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4061 so that we don't link in clock_gettime unnecessarily.
4063 2000-07-17 Paul D. Smith <psmith@gnu.org>
4065 * i18n/ja.po: New version of the translation file.
4067 2000-07-07 Paul D. Smith <psmith@gnu.org>
4069 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4070 the offset calculation.
4071 (name_mtime): Replace EINTR test with EINTR_SET macro.
4073 2000-07-07 Paul Eggert <eggert@twinsun.com>
4077 * remake.c (update_file_1):
4078 Avoid spurious rebuilds of archive members due to their
4079 timestamp resolution being only one second.
4080 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4081 the clock's resolution being lower than file timestamps'.
4082 When warning about future timestamps, report only the discrepancy,
4083 not the absolute value of the timestamp and the current time.
4085 * file.c (file_timestamp_now): New arg RESOLUTION.
4086 * filedef.h (file_timestamp_now): Likewise.
4087 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4089 2000-07-05 Paul D. Smith <psmith@gnu.org>
4091 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4092 to listp. Fixes PR/1793.
4094 2000-06-26 Paul Eggert <eggert@twinsun.com>
4096 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4098 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4100 * remake.c (f_mtime): Remove unused var memtime.
4102 2000-06-25 Martin Buchholz <martin@xemacs.org>
4104 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4105 Ran spell-check on make.texinfo.
4107 2000-06-23 Paul D. Smith <psmith@gnu.org>
4109 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4110 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4111 * make.h: Define these macros.
4113 * Version 3.79.1 released.
4115 * configure.in: Add a new option, --disable-nsec-timestamps, to
4116 avoid using sub-second timestamps on systems that support it. It
4117 can lead to problems, e.g. if your makefile relies on "cp -p".
4118 * README.template: Document the issue with "cp -p".
4120 * config.guess, config.sub: Updated.
