255 which allows the caller to get the index of the matching directory.
257 * make.h (vpath_search): Update prototype.
259 * remake.c (library_search): Implement linker-compatible library
260 search. Use the new VPATH_SEARCH index functionality to keep track

265 the VPATH_SEARCH call.
267 * doc/make.texi (Directory Search for Link Libraries): Describe the

357 2009-10-03 Paul Smith <psmith@gnu.org>
359 * make.h: Include <alloca.h> even on systems where __GNUC__ is
360 defined. Not sure why it was done the other way.
361 Requested by David Boyce <dsb@boyski.com>.
363 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
365 * dep.h (dep): Add the DONTCARE bitfield.
367 * filedef.h (file):Add the NO_DIAG bitfield.
369 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,

379 that caused the failure.
380 (update_file_1): Use NO_DIAG instead of DONTCARE to decide

419 double-colons have a different meaning. Savannah bug #27497.
421 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
423 * configh.dos.template: Remove unconditional definition of
424 SYS_SIGLIST_DECLARED.
425 Include <sys/version.h> because ports of GCC 4.3.0 and later no
426 longer include it, so macros like __DJGPP_MINOR__ are no longer
427 defined automatically.
429 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
430 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
431 instead of using the hardcoded ones.
432 (SUBDIRS): doc subdir added.
433 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
434 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
435 create html formated docs. texi2html may not be ported to DOS.
436 (make.info, make.dvi, make.ps, make.html): Make targets depend on
438 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
439 -I switch to look in ./ instead of ./doc.
440 (html): Target depend on html-recursive instead of make_1.html.
441 (make_1.html): Removed.
442 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
443 (all-recursive): Allow for more than one subdir in the build
445 (mostlyclean-recursive, clean-recursive, distclean-recursive)
446 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
447 (tags-recursive): Allow for more than one subdir in the build
449 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
450 targets. Enter into doc/ to produce the targets.
451 (all-am): $(INFO_DEPS) replaced by info.
453 2009-09-26 Paul Smith <psmith@gnu.org>
455 * read.c (record_files): Use free_ns() to free struct nameseq.
458 * rule.c (freerule): Use free_dep_chain().
460 * read.c (record_files): Free FILENAMES chain for implicit rules.
461 (eval): Static pattern targets go into the string cache.
463 * function.c (string_glob): Free NAME in the nameseq chain.
465 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
467 * implicit.c (pattern_search): Terminate early if we haven't
468 found any rules to try (performance improvement).
470 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
472 * implicit.c (pattern_search): Merge three parallel arrays,
473 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
474 of struct TRYRULE. In the old version the latter two arrays
475 had insufficient length.
477 2009-09-24 Paul Smith <psmith@gnu.org>
479 * implicit.c (pattern_search): Add back support for order-only
480 prerequisites for secondary expansion implicit rules, that were
481 accidentally dropped. If we find a "|", enable order-only mode
482 and set IGNORE_MTIME on all deps that are seen afterward.
483 (pattern_search): Fix memory leaks: for intermediate files where
484 we've already set the file variable and pattern variable sets, be
485 sure to either save or free them as appropriate.
487 2009-09-23 Paul Smith <psmith@gnu.org>
489 Rework the way secondary expansion is stored, for efficiency.
490 This changes secondary expansion so that ONLY WHEN we know we have
491 a possibility of needing secondary expansion, do we defer the
492 secondary expansion. This means more parsing the deps but we use
493 a lot less memory (due to the strcache). Also, this fixes
496 * read.c (eval): Don't parse the dep string here anymore.
497 (record_files): Take the dep argument as an unparsed string. If
498 secondary expansion is enabled AND the prereq string has a '$' in
499 it, then set NEED_2ND_EXPANSION and keep the entire string.
500 Otherwise, parse the dep string here to construct the dep list
501 with the names in the strcache.
503 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
504 duplicate the name string (others are in the strcache).
506 * implicit.c: Remove struct idep and free_idep_chain(): unused.
507 (struct patdeps): New structure to store prereq information.
508 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
509 which prerequisites need expansion, and expand only those.
511 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
512 and enter_prereqs(). split_prereqs() takes a fully-expanded string
513 and splits it into a DEP list, handling order-only prereqs.
514 (enter_prereqs): This function enters a list of DEPs into the file
515 database. If there's a stem defined, expand any pattern chars.
516 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
517 set. Use the above functions.
518 (snap_deps): Only perform second expansion on prereqs that need it,
519 as defined by the NEED_2ND_EXPANSION flag.
520 (print_prereqs): New function to print the prereqs
521 (print_file): Call print_prereqs() rather than print inline.
523 * hash.h (STRING_COMPARE): Take advantage of strcache() by
525 (STRING_N_COMPARE): Ditto.
526 (ISTRING_COMPARE): Ditto.
528 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
529 (parse_file_seq): Return void*
530 * read.c (parse_file_seq): Return void*.
531 (eval): Invoke macroized version of parse_file_seq()
532 * default.c (set_default_suffixes): Ditto.
533 * file.c (split_prereqs): Ditto.
534 * function.c (string_glob): Ditto.
535 * main.c (main): Ditto.
536 * rule.c (install_pattern_rule): Ditto.
538 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
540 2009-09-16 Paul Smith <psmith@gnu.org>
542 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
544 * dep.h: Create alloc_dep() / free_dep() macros.
546 * implicit.c (pattern_search): Take advantage of the new
547 parse_file_seq() to add the directory prefix to each prereq.
549 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
550 all. Avoid reversing chains. Support adding prefixes.
551 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
552 cached/non-cached results.
553 (eval): Remove multi_glob() & invoke new parse_file_seq().
554 * rule.c (install_pattern_rule): Ditto.
555 * main.c (main): Ditto.
556 * implicit.c (pattern_search): Ditto.
557 * function.c (string_glob): Ditto.
558 * file.c (parse_prereqs): Ditto.
559 * default.c (set_default_suffixes): Ditto.
561 * variable.c (parse_variable_definition): Don't run off the end of
562 the string if it ends in whitespace (found with valgrind).
564 * commands.c (set_file_variables): Keep space for all targets in
565 $? if -B is given (found with valgrind).
567 2009-09-15 Paul Smith <psmith@gnu.org>

570 (xcalloc): Add new function.
571 * make.h: New declarations.
573 * ar.c (ar_glob_match): New calling method for concat().

585 * job.c (new_job): Ditto.
586 * read.c (parse_file_seq): Ditto.
587 * vmsfunctions.c (opendir): Ditto.
589 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
591 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
592 inside the loop that looks up environment for PATH.
594 2009-08-31 Eli Zaretskii <eliz@gnu.org>
596 * function.c (windows32_openpipe): Update envp after calling
597 sync_Path_environment.
599 2009-08-02 Paul Smith <psmith@gnu.org>
601 * remake.c (notice_finished_file): Ensure file->cmds is not null
602 before looping through them. Fixes Savannah bug #21824.
604 * doc/make.texi (Wildcard Examples): Clarify when objects is
605 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
606 (Include): Clarify the behavior of -include.
607 Fixes Savannah bug #18963.
609 2009-08-01 Paul Smith <psmith@gnu.org>
611 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
612 etc. come on the command line. Fixes Savannah bug #27093.
614 * expand.c (expand_argument): If the argument is large enough use
615 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
617 * variable.c (do_variable_definition): Avoid using alloca() to
618 hold values, which can be large. Fixes Savannah bug #23960.
620 * job.c (new_job): Use memmove() instead of strcpy() since both
621 pointers are in the same memory block. Fixes Savannah bug #27148.
622 Patch by Petr Machata.
624 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
626 * job.c (construct_command_argv_internal): Add "ulimit" and
627 "unset" to the sh_cmds for Unixy shells.
629 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
631 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
632 that set make_cv_sys_gnu_glob, so they are also correctly set
633 when the cache has been populated before.
635 2009-07-04 Eli Zaretskii <eliz@gnu.org>
637 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
638 exist, as realpath(3) does where it's supported.
640 2006-07-04 Eli Zaretskii <eliz@gnu.org>
642 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
643 (abspath): Support systems that define HAVE_DOS_PATHS (have
644 drive letters in their file names). Use IS_PATHSEP instead of a
645 literal '/' comparison. Fixes Savannah bug #26886.
647 2009-06-14 Paul Smith <psmith@gnu.org>
649 * remake.c (update_file_1): Remember the original file we marked
650 as updating, so we can clear that flag again. If we find a target
651 via vpath, FILE might change.
652 (check_dep): Ditto. Fixes Savannah bug #13529.
653 Patch by Reid Madsen <reid.madsen@tek.com>.
655 2009-06-13 Paul Smith <psmith@gnu.org>
657 * doc/make.texi (MAKEFILES Variable): Be explicit that files
658 included by MAKEFILES cannot give default goals.
659 * read.c (eval): If set_default is not set, pass the no-default-goal
660 value when we read included makefiles. Fixes Savannah bug #13401.
662 * ar.c (ar_name): Ensure that targets with empty parens aren't
663 considered archive member references: archive members must have a
664 non-empty "member" string. Fixes Savannah bug #18435.
666 * function.c (string_glob): Rely on multi_glob() to determine
667 whether files exist or not. Remove call to file_exists_p() which
668 is not always correct. Fixes Savannah bug #21231.
669 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
670 then only files that really exist will be returned.
671 * dep.h: Add new argument to multi_glob().
672 * rule.c (install_pattern_rule): Ditto.
673 * read.c (eval): Ditto.
674 * main.c (main): Ditto.
675 * implicit.c (pattern_search): Ditto.
676 * file.c (parse_prereqs): Ditto.
677 * default.c (set_default_suffixes): Ditto.
679 2009-06-09 Paul Smith <psmith@gnu.org>
681 * commands.c (set_file_variables): If always_make_flag is set,
682 always add the prereq to $?. Fixes Savannah bug #17825.
684 * remake.c (update_file_1): When rebuilding deps of FILE, also try
685 to rebuild the deps of all the also_make targets for that file.
686 Fixes Savannah bug #19108.
688 * implicit.c (pattern_search): Undo test for is_target, added by
689 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
690 Rule Search Algorithm". Fixes Savannah bug #17752.
692 * main.c (clean_jobserver): Clear the jobserver_fds options and
693 set job_slots to the default when we clean up.
694 (define_makeflags): Return the new MAKEFLAGS value.
695 (main): Reset MAKEFLAGS in the environment when we re-exec.
696 Fixes Savannah bug #18124.
698 2009-06-08 Paul Smith <psmith@gnu.org>
700 * read.c (eval): Collapse continuations post-semicolon on target-
701 specific variables. Fixes Savannah bug #17521.
703 2009-06-07 Paul Smith <psmith@gnu.org>
705 * job.c (reap_children): For older systems without waitpid() (are
706 there any of these left?) run wait(2) inside EINTRLOOP to handle
707 EINTR errors. Fixes Savannah bug #16401.
709 * (various): Debug message cleanup. Fixes Savannah bug #16469.
711 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
713 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
714 not the end, to catch second expansion $(eval ...) defining new
715 target/prereq relationships during snap_deps.
716 Fixes Savannah bug #24622.
718 * read.c (record_files): The second-expansion "f->updating" hack
719 was not completely correct: if assumed that the target with
720 commands always had prerequisites; if one didn't then the ordering
721 was messed up. Fixed for now to use f->updating to decide whether
722 to preserve the last element in the deps list... but this whole
723 area of constructing and reversing the deps list is too confusing
724 and needs to be reworked. Fixes Savannah bug #21198.
726 2009-06-06 Paul Smith <psmith@gnu.org>
728 * hash.c (hash_insert): Remove useless test for NULL.
729 Fixes Savannah bug #21823.
731 * make.h: Move SET_STACK_SIZE determination to make.h.
732 * main.c (main): New global variable, STACK_LIMIT, holds the
733 original stack limit when make was started.
734 * job.c (start_job_command): Reset the stack limit, if we changed it.
735 Fixes Savannah bug #22010.
737 * remake.c (check_dep): Only set the target's state to not-started
738 if it's not already running. Found this while testing -j10 builds
739 of glibc: various targets were being rebuilt multiple times.
740 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
743 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
744 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
747 2009-06-04 Paul Smith <psmith@gnu.org>
749 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
751 * maintMakefile: Modify access of config and gnulib Savannah
752 modules to use GIT instead of CVS.
754 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
755 Fixes Savannah bug #24655.
757 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
758 this can happen during some invocations of $(eval ...) for example.
759 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
761 2009-06-02 Paul Smith <psmith@gnu.org>
763 * configure.in: Check for fileno()
764 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
765 for the makefile file so invocations of $(shell ...) don't inherit it.
766 Fixes Savannah bug #24277.
768 2009-06-01 Paul Smith <psmith@gnu.org>
770 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
771 expansion was handled incorrectly. Rework the default goal
772 handling to save the variable only. Remove default_goal_file and
774 * read.c (eval): Check default_goal_var, not default_goal_name.
775 * read.c (record_target_var): Don't check default_goal_file here.
777 2009-05-31 Paul Smith <psmith@gnu.org>
779 * main.c (main): Expand the .DEFAULT_GOAL variable before using
780 it, and if the multi_glob() returns nothing (say it expanded to
781 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
783 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
784 $(and ..) to the reference. Fixes Savannah bug #25694.
786 * make.1: Be clear that some recipes will be executed even with -n.
787 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
789 * doc/make.texi (Override Directive): Make more clear how
790 overrides and appends interact.
791 Elucidates part of Savannah bug #26207.
793 * read.c (record_target_var): Don't reset the origin on
794 target-specific variables; try_variable_definition() will handle
795 this correctly. Fixes Savannah bug #26207.
797 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
798 Fixes Savannah bug #25712.
800 * implicit.c (pattern_search): Keep a pointer to the beginning of
801 the filename and save that instead of the constructed pointer.
802 Fixes Savannah bug #26593.
803 Patch by Mark Seaborn <mrs@mythic-beasts.com>
805 2009-05-30 Paul Smith <psmith@gnu.org>
807 * doc/make.texi (Multi-Line): Add a description of the new abilities
808 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
809 "command sequence" vs. "recipe" syntax.
810 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
811 after a define, to create variables with those flavors.
813 2009-05-25 Paul Smith <psmith@gnu.org>
815 Reworked the parser for variable assignments to allow multiple
816 modifiers, and in any order. Also allows variable and
817 prerequisites to be modifier names ('export', 'private', etc.)
819 * NEWS: Add notes about user-visible changes.
821 * read.c (struct vmodifiers): Remember what modifiers were seen.
822 (parse_var_assignment): New function to parse variable assignments.
823 (eval): Call the new function. Handle variable assignments earlier.
825 * variable.c (parse_variable_definition): Only parse; don't create var.
826 (assign_variable_definition): Call parse, then create the var.
828 2009-05-24 Paul Smith <psmith@gnu.org>
830 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
831 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
833 2009-03-14 Eli Zaretskii <eliz@gnu.org>
835 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
836 Fixes Savannah bug #25412.
838 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
839 prototype for xmalloc.
840 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
841 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
842 Loop over an array of extensions, instead of duplicating the same
843 code inline. Use SearchPath followed by CreateFile, instead of
844 the obsolete OpenFile. Fixes Savannah bug #17277.
845 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
846 to `find_file'. Fixes Savannah bug #25662.
848 2009-03-07 Eli Zaretskii <eliz@gnu.org>
850 * function.c (func_shell): Don't close pipedes[1] if it is -1.
851 Fixes Savannah bug #20495.
853 2009-02-28 Ralf Wildenhues <address@hidden>
855 * doc/make.texi (Instead of Execution): Document interaction of
856 -t with phony targets.
858 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
860 Introduce a new keyword "private" which applies to target-specific
861 variables and prevents their values from being inherited.
863 * variable.h (struct variable): Add private_var flag to each variable.
864 Add a flag to specify which list entry switches to the parent target.

884 2008-09-30 Eli Zaretskii <eliz@gnu.org>
886 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
889 * w32/subproc/build.bat (GCCBuild): Likewise.
891 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
893 * job.c (construct_command_argv_internal): Avoid extra backslash
894 in batch-mode Unixy shells. Under DB_JOBS, display the contents
897 2008-05-31 Eli Zaretskii <eliz@gnu.org>
899 * README.W32.template: Remove obsolete text about non-support for
900 -jN without Unixy shell. Remove obsolete text about not supplying
901 Visual Studio project files (we do supply them). Modify text to
902 prefer GCC builds to MSC builds.
904 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
906 * doc/make.texi (Empty Targets): Fix typo.
908 2008-03-27 Paul Smith <psmith@gnu.org>

921 `value' field is NULL.
923 2007-12-22 Eli Zaretskii <eliz@gnu.org>
925 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
927 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
928 (TEXINFOS): Value changed to `doc/make.texi'.
929 (.SUFFIXES): Use .texi instead of .texinfo.
930 (make.info, make.dvi): Depend on doc/make.texi.
931 (.texi.info): New target, instead of ".texinfo.info". Change -I
932 switch to $(MAKEINFO) to look in doc/. Use --no-split.
933 (.texi): New target, instead of ".texinfo". Change -I switch to
934 $(MAKEINFO) to look in doc/. Use --no-split.
935 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
936 switch to $(MAKEINFO) to look in doc/.
937 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

940 (html, make_1.html): New targets.
941 (.PHONY): Add "html".
942 (.SUFFIXES): Add .html.
944 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
946 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
947 HAVE_DECL_SYS_SIGLIST.
949 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
950 build does not use child_execute_job.
952 * variable.c (define_automatic_variables) [__MSDOS__]: Always
953 export the SHELL environment variable to the child.
955 2007-12-22 Eli Zaretskii <eliz@gnu.org>
957 * config.h.W32: Include sys/types.h.
958 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

974 * remake.c (f_mtime): Print time difference values between 100 and
975 ULONG_MAX in fixed-point notation rather than in exponention notation.
977 2007-10-12 Eli Zaretskii <eliz@gnu.org>
979 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
980 a more complex value than a simple shell: if it's not a default
981 shell now then expand it and see if is a default shell then.
983 2007-10-10 Eli Zaretskii <eliz@gnu.org>
985 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
986 pathnames, with const strings.
987 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

990 2007-10-10 Paul Smith <psmith@gnu.org>
992 * make.h: Add a prototype for w32_kill() (change suggested by
993 Yongwei Wu <wuyongwei@gmail.com>).
995 2007-09-21 Eli Zaretskii <eliz@gnu.org>
997 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1000 2007-09-12 Paul Smith <psmith@gnu.org>
1002 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1003 Provided by Diego Biurrun <diego@biurrun.de>
1004 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1005 Provided by Diego Biurrun <diego@biurrun.de>
1007 2007-09-11 Paul Smith <psmith@gnu.org>
1009 * doc/make.texi (Special Variables): Moved this into the "How to
1010 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1011 (MAKEFILE_LIST) No longer a section; this was added into the
1012 "Special Variables" section.
1013 (Rule Introduction): Reference .RECIPEPREFIX.
1014 (Simple Makefile): Ditto.
1015 (Rule Syntax): Ditto.
1016 (Command Syntax): Ditto.
1017 (Error Messages): Ditto.
1019 2007-09-10 Paul Smith <psmith@gnu.org>
1021 * commands.c (print_commands): Don't print an extra line in the
1022 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1024 * read.c (construct_include_path): Add the full string to the cache; we
1025 were chopping the last char.
1027 * NEWS: Announce the .RECIPEPREFIX special variable.
1028 * variable.c (lookup_special_var): Rename from handle_special_var().
1029 (lookup_variable): Call the new name.
1030 (set_special_var): New function: handle setting of special variables.
1031 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1032 (do_variable_definition): Call it.
1033 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1034 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1035 * main.c (main): Create the .RECIPEPREFIX special variable.
1036 * read.c (eval): Remove the cmd_prefix characters from the command
1037 scripts here, so they're not stored in the commands array at all,
1038 rather than waiting and stripping them out during command construction.
1039 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1041 2007-08-15 Paul Smith <psmith@gnu.org>
1043 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1044 file has had the section info removed, so add some to make.texi
1045 before we include it.
1047 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1049 * remake.c (check_dep): Reset the target state for intermediate
1050 files. They might have been considered before but not updated
1051 then (order-only for example) but they will be this time.
1052 Fixes Savannah bug #'s 3330 and 15919.
1054 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1056 Fix Savannah bug #20549:
1057 * function.c (func_shell): Call construct_command_argv with zero
1059 * job.c (construct_command_argv_internal): New argument FLAGS; all
1061 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore

1065 2007-07-13 Paul Smith <psmith@gnu.org>
1067 * file.c (expand_deps): Use variable_buffer as the start of the
1068 buffer, not the original pointer (in case it was reallocated).
1069 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1070 Fixes Savannah bug #20452.

1087 Fixes Savannah bug #20018.
1089 * expand.c (variable_expand_for_file): Preserve the value of
1090 reading_file rather than setting it to 0 at the end.

1109 2007-05-08 Paul Smith <psmith@gnu.org>
1111 Fix Savannah bug #19656:
1113 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1115 * make.h: Change all case-insensitive string compares to use
1116 strcasecmp() (from POSIX). If we don't have that but do have one
1117 of the others, define strcasecmp to be one of those instead. If
1118 we don't have any, declare a prototype for our own version.
1120 * misc.c (strcasecmp): Use this if we can't find any native
1121 case-insensitive string comparison function.
1122 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1123 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1125 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1126 strcasecmp() instead of stricmp().
1127 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1128 instead of strcmpi().
1129 * acinclude.m4: Remove the strcasecmp() check from here.
1131 2007-03-21 Paul Smith <psmith@gnu.org>
1133 * configure.in: Don't turn on case-insensitive file system support
1134 if --disable-... is given. Fixes Savannah bug #19348.
1136 2007-03-19 Paul Smith <psmith@gnu.org>
1138 * ALL: Use the strcache for all file name strings, or other
1139 strings which we will never free. The goal is to save memory by
1140 avoiding duplicate copies of strings. However, at the moment this
1141 doesn't save much memory in most situations: due to secondary
1142 expansion we actually save prerequisite lists twice (once before
1143 the secondary expansion, and then again after it's been parsed
1144 into individual file names in the dep list). We will resolve this
1145 in a future change, by doing the parsing up-front for targets
1146 where secondary expansion is not set.
1148 Moving things into the strcache also allows us to use const
1149 pointers in many more places.
1151 2007-01-03 Paul Smith <psmith@gnu.org>
1153 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1154 the function, not just the first. Fixes Savannah bug #18680.
1156 2006-11-18 Paul Smith <psmith@gnu.org>
1158 * strcache.c (strcache_add_len): Don't allocate a new buffer
1159 unless the string is not already nil-terminated. Technically this
1160 is a violation of the standard, since we may be passed an array
1161 that is not long enough to test one past. However, in make this
1162 is never true since we only use nil-terminated strings or
1163 sub-strings thereof.
1165 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1167 * main.c: New global cmd_prefix, defaults to '\t'.
1168 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1171 * dir.c: Constified.
1172 (dir_contents_file_exists_p): Check for an error return from
1173 readdir(), just in case.
1175 * commands.c: Constified.
1176 * default.c: Constified.
1177 * expand.c: Constified.
1178 * function.c: Partial constification.

1185 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1187 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1188 backslashes and drive letters as absolute.
1190 2006-10-22 Paul Smith <psmith@gnu.org>

1197 * arscan.c: Constified.
1199 2006-09-30 Paul Smith <psmith@gnu.org>
1201 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1202 point to lastword since the example was updated.
1203 Fixes Savannah bug #16304.
1204 (Secondary Expansion): Correct example description.
1205 Fixes Savannah bug #16468.
1206 (Makefile Contents): Clarify that comments cannot appear within
1207 variable references or function calls.
1208 Fixes Savannah bug #16577.
1209 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1210 Fixes Savannah bug #17701.
1211 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1213 prerequisites. Fixes Savannah bug #17880.
1214 (Rule Syntax): "lise" -> "list"
1215 (Multiple Rules): ... -> @dots{}
1216 (Splitting Lines): ditto.
1218 * remake.c (update_file_1): Prereqs that don't exist should be
1219 considered changed, for the purposes of $?.
1220 Fixes Savannah bug #16051.

1269 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1270 inner-scope variables don't mask outer-scope variables.

1331 Declare and define sh_chars_sh[].
1333 2006-03-23 Paul D. Smith <psmith@gnu.org>
1335 * configure.in: Look for build.sh.in in $srcdir so it will be
1336 built for remote configurations as well.
1338 * Makefile.am: Make sure to clean up build.sh during distclean.
1339 Fixes Savannah bug #16166.
1341 * misc.c (log_access): Takes a const char *.

1347 * implicit.c (pattern_search): Call set_file_variables only
1348 if we have prerequisites that need second expansion. Fixes
1349 Savannah bug #16140.
1351 2006-03-19 Paul D. Smith <psmith@gnu.org>
1353 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1354 memory on hosts that don't support it directly.

1357 make sure I don't forget any).
1359 * main.c (clean_jobserver): Move jobserver cleanup code into a new

1369 allow multiple concurrent runs.
1370 Patch from Joseph Myers <joseph@codesourcery.com>
1372 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1375 * misc.c (alloc_dep, free_dep): New functions.
1376 (copy_dep_chain): Copy stem.
1377 (free_dep_chain): Use free_dep.
1378 * read.c (record_files): Store stem in the dependency line.
1379 * file.c (expand_deps): Use stem stored in the dependency line. Use
1380 free_dep_chain instead of free_ns_chain.
1381 * implicit.c (pattern_search): Use alloc_dep and free_dep.

1393 Fixes Savannah bug #15913.
1395 2006-03-09 Paul Smith <psmith@gnu.org>
1397 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1398 listed non-existent files as changed. Turns out there's a bug in
1399 the Linux kernel builds which means that this change causes
1400 everything to rebuild every time. We will re-introduce this fix
1401 in the next release, to give them time to fix their build system.
1402 Fixes Savannah bug #16002.
1403 Introduces Savannah bug #16051.

1420 2006-02-19 Paul D. Smith <psmith@gnu.org>
1422 * commands.c (set_file_variables): Realloc, not malloc, the static
1423 string values to avoid memory leaks.
1425 * expand.c (recursively_expand_for_file): Only set reading_file to
1426 an initialized value.
1428 * implicit.c (pattern_search): We need to make a copy of the stem
1429 if we get it from an intermediate dep, since those get freed.
1431 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1433 (enter_file) [VMS]: Ditto.

1438 * job.c (construct_command_argv_internal): Fix last change.
1440 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1441 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1442 the calls to _beginthreadex.
1444 * expand.c (recursively_expand_for_file): Initialize `save' to
1445 prevent compiler warnings.
1447 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1449 * job.c (construct_command_argv_internal): Don't create a temporary
1450 script/batch file if we are under -n. Call _setmode to switch the
1451 script file stream to text mode.

1455 * variable.c (merge_variable_set_lists): Don't try to merge the
1456 global_setlist. Not only is this useless, but it can lead to
1457 circularities in the linked list, if global_setlist->next in one
1458 list gets set to point to another list which also ends in

1462 2006-02-15 Paul D. Smith <psmith@gnu.org>
1464 Fix for Savannah bug #106.
1466 * expand.c (expanding_var): Keep track of which variable we're
1467 expanding. If no variable is being expanded, it's the same as
1469 * make.h (expanding_var): Declare it.
1470 * expand.c (recursively_expand_for_file): Set expanding_var to the
1471 current variable we're expanding, unless there's no file info in
1472 it (could happen if it comes from the command line or a default
1473 variable). Restore it before we exit.

1485 * read.c (eval): Even if the included filenames expands to the
1486 empty string we still need to free the allocated buffer.
1488 * implicit.c (pattern_search): If we allocated a variable set for
1489 an impossible file, free it.
1490 * variable.c (free_variable_set): New function.
1491 * variable.h: Declare it.
1493 * read.c (read_all_makefiles): Makefile names are kept in the
1494 strcache, so there's never any need to alloc/free them.
1497 * main.c (main): Add "archives" to the .FEATURES variable if
1498 archive support is enabled.

1509 * (ALL FILES): Updated copyright and license notices.
1511 2006-02-10 Paul D. Smith <psmith@gnu.org>
1513 A new internal capability: the string cache is a read-only cache
1514 of strings, with a hash table interface for fast lookup. Nothing
1515 in the cache will ever be freed, so there's no need for reference
1516 counting, etc. This is the beginning of a full solution for
1517 Savannah bug #15182, but for now we only store makefile names here.
1519 * strcache.c: New file. Implement a read-only string cache.
1520 * make.h: Add prototypes for new functions.
1521 * main.c (initialize_global_hash_tables): Initialize the string cache.
1522 (print_data_base): Print string cache stats.
1523 * read.c (eval_makefile): Use the string cache to store makefile
1524 names. Rewrite the string allocation to be sure we free everything.

1528 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1529 directory time stamp didn't change, except on FAT filesystems.

1554 -W, don't overwrite it with the real mtime.

1573 * filedef.h (struct file): Add a new LAST pointer.
1575 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1576 the comparison. For 64-bits systems the result of the subtraction
1577 might not fit into an int. Use comparison instead.
1578 Fixes Savannah bug #15534.

1581 the changes made in 3.81 for backslash/newline and SHELL handling.

1601 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1603 * remake.c (update_goal_chain): Set g->changed instead of
1604 incrementing it, as it is only 8-bit wide, and could overflow if
1605 many commands got started in update_file.
1607 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1609 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1610 MAXIMUM_WAIT_OBJECTS.
1611 (process_wait_for_any_private): Change dimension of handles[]
1612 array to MAXIMUM_WAIT_OBJECTS.
1613 (process_used_slots): New function.
1614 (process_register): Don't register more processes than the
1615 available number of slots.
1616 (process_easy): Don't start new processes if all slots are used up.
1618 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1619 are already more children than sub_proc.c can handle, behave as if
1620 the load were too high.
1621 (start_job_command): Fix a typo in error message when process_easy
1624 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1626 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1627 the shell is not sh.exe.
1629 * job.c (create_batch_file): Renamed from create_batch_filename;
1630 all callers changed. Don't close the temporary file; return its
1631 file descriptor instead. New arg FD allows to return the file
1633 (construct_command_argv_internal): Use _fdopen instead of fopen to
1634 open the batch file.
1636 2006-01-04 Paul D. Smith <psmith@gnu.org>
1638 * readme.vms: Updates for case-insensitive VMS file systems from
1639 Hartmut Becker <Hartmut.Becker@hp.com>.
1640 * dir.c (vms_hash): Ditto.
1641 * vmsify.c (copyto): Ditto.
1642 * vmsfunctions.c (readdir): Ditto.
1644 * make.1: Add a section on the exit codes for make.
1646 * doc/make.texi: A number of minor updates to the documentation.
1648 2006-01-03 Paul D. Smith <psmith@gnu.org>
1650 * remake.c (update_file_1): Mark a prerequisite changed if it
1653 * read.c (eval): Be sure to strip off trailing whitespace from the
1654 prerequisites list properly. Also, initialize all fields in
1655 struct dep when creating a new one.
1657 2005-12-28 Paul D. Smith <psmith@gnu.org>
1659 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1660 disable warnings for MSC.
1661 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1663 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1665 * doc/make.texi (Execution): Add a footnote about changes in
1666 handling of backslash-newline sequences. Mention the differences
1667 on MS-DOS and MS-Windows.
1669 * NEWS: More details about building the MinGW port and a pointer
1670 to README.W32. Fix the section name that describes the new
1671 backward-incompatible processing of backslash-newline sequences.
1672 The special processing of SHELL set to "cmd" is only relevant to
1673 MS-Windows, not MS-DOS.
1675 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1677 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1678 to DWORD, to avoid compiler warnings.
1679 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1680 use %ld in format, to avoid compiler warnings.
1682 * doc/make.texi (Special Targets): Fix a typo.
1683 (Appending): Fix cross-reference to Setting.
1684 (Special Variables, Secondary Expansion, File Name Functions)
1685 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1686 periods after a sentence.
1687 (Execution): Add @: after "e.g.".
1688 (Environment): Fix punctuation.
1689 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1690 (Shell Function, Target-specific): Add @: after "vs."
1692 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1694 * read.c (record_target_var): Initialize variable's export field
1695 with v_default instead of leaving it "initialized" by whatever
1696 garbage happened to be on the heap.
1698 2005-12-12 Paul D. Smith <psmith@gnu.org>
1700 * make.1: Fix some display errors and document all existing options.
1701 Patch by Mike Frysinger <vapier@gentoo.org>.
1703 2005-12-11 Paul D. Smith <psmith@gnu.org>
1705 * implicit.c (pattern_search): If 2nd expansion is not set for
1706 this implicit rule, replace the pattern with the stem directly,
1707 and don't re-expand the variable list. Along with the other
1708 .SECONDEXPANSION changes below, fixes bug #13781.
1710 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1712 * implicit.c (pattern_search): Mark other files that this rule
1713 builds as targets so that they are not treated as intermediates
1714 by the pattern rule search algorithm. Fixes bug #13022.
1716 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1718 * remake.c (notice_finished_file): Propagate the change of
1719 modification time to all the double-colon entries only if
1720 it is the last one to be updated. Fixes bug #14334.
1722 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1724 * function.c (func_flavor): Implement the flavor function which
1725 returns the flavor of a variable.
1726 * doc/make.texi (Functions for Transforming Text): Document it.
1727 * NEWS: Add it to the list of new functions.
1729 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1731 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1733 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1734 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1736 2005-10-26 Paul Smith <psmith@gnu.org>
1738 * read.c (record_files): Don't set deps flags if there are no deps.
1739 * maintMakefile: We only need to build the templates when we are
1740 creating a distribution, so don't do it for "all".
1742 2005-10-24 Paul D. Smith <psmith@gnu.org>
1744 Make secondary expansion optional: its enabled by declaring the
1745 special target .SECONDEXPANSION.
1747 * NEWS: Update information on second expansion capabilities.
1748 * doc/make.texi (Secondary Expansion): Document the
1749 .SECONDEXPANSION special target and its behavior.
1750 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1751 prerequisite list was found in a static pattern rule.
1752 (free_dep_chain): Declare a prototype.
1753 * file.c (parse_prereqs): New function: break out some complexity
1755 (expand_deps): If we aren't doing second expansion, replace % with
1756 the stem for static pattern rules. Call the new function.
1757 * filedef.h (parse_prereqs): Declare a prototype.
1758 * implicit.c (pattern_search): Initialize the new staticpattern
1760 * main.c (second_expansion): Declare a global variable to remember
1761 if the special target has been seen. Initialize the new
1762 staticpattern field for prerequisites.
1763 * make.h: Extern for second_expansion.
1764 * misc.c (free_dep_chain): New function: frees a struct dep list.
1765 * read.c (read_all_makefiles): Initialize the staticpattern field.
1766 (eval_makefile): Ditto.
1767 (record_files): Check for the .SECONDEXPANSION target and set
1768 second_expansion global if it's found.
1769 Use the new free_dep_chain() instead of doing it by hand.
1770 Set the staticpattern field for prereqs of static pattern targets.
1772 2005-10-16 Paul D. Smith <psmith@gnu.org>
1774 * main.c (main): Set CURDIR to be a file variable instead of a
1775 default, so that values of CURDIR inherited from the environment
1776 won't override the make value.
1778 2005-09-26 Paul D. Smith <psmith@gnu.org>
1780 * job.c (construct_command_argv_internal): If the line is empty
1781 remember to free the temporary argv strings.
1784 2005-09-16 Paul D. Smith <psmith@gnu.org>
1786 * job.c (start_job_command): The noerror flag is a boolean (single
1787 bit); set it appropriately.
1788 Reported by Mark Eichin <eichin@metacarta.com>
1790 2005-08-29 Paul D. Smith <psmith@gnu.org>
1792 * function.c (func_error): On Windows, output from $(info ...)
1793 seems to come in the wrong order. Try to force it with fflush().
1795 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1797 * read.c (record_files): Move code that sets stem for static
1798 pattern rules out of the if (!two_colon) condition so it is
1799 also executed for two-colon rules. Fixes Savannah bug #13881.
1801 2005-08-08 Paul D. Smith <psmith@gnu.org>
1803 * make.h: Don't test that __STDC__ is non-0. Some compilers
1804 (Windows for example) set it to 0 to denote "ISO C + extensions".
1807 2005-08-07 Paul D. Smith <psmith@gnu.org>
1809 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1810 conditional (slightly different version of a fix from Eli).
1812 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1813 If make is running in parallel without -k and two jobs die in a
1814 row, but not too close to each other, then make will quit without
1815 waiting for the rest of the jobs to die.
1817 * main.c (die): Don't reset err before calling reap_children() the
1818 second time: we still want it to be in the error condition.
1819 * job.c (reap_children): Use a static variable, rather than err,
1820 to control whether or not the error message should be printed.
1822 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1824 * w32/subproc/sub_proc.c: Include signal.h.
1825 (process_pipe_io, process_file_io): Pass a pointer to a local
1826 DWORD variable to GetExitCodeProcess. If the exit code is
1827 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1829 * job.c [WINDOWS32]: Include windows.h.
1830 (main_thread) [WINDOWS32]: New global variable.
1831 (reap_children) [WINDOWS32]: Get the handle for the main thread
1832 and store it in main_thread.
1834 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1835 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1836 doing anything else. When we are done, close the main thread
1837 handle and exit with status 130.
1839 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1841 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1844 * main.c (find_and_set_default_shell): If found a DOSish shell,
1845 set sh_found and the value of default_shell, and report the
1846 findings in debug mode.
1848 * job.c (construct_command_argv_internal): Check unixy_shell, not
1849 no_default_sh_exe, to decide whether to use Unixy or DOSish
1852 * README.W32: Update with info about the MinGW build.
1854 * build_w32.bat: Support MinGW.
1856 * w32/subproc/build.bat: Likewise.
1858 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1859 printing DWORD args.
1861 * function.c (windows32_openpipe): Fix format strings for printing
1864 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1866 (start_job_command): Fix format string for printing the result of
1868 (start_job_command) [WINDOWS32]: Do not define.
1869 (exec_command): Fix format string for printing HANDLE args.
1871 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1872 to avoid compiler warnings.
1873 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1874 (Note: some of these fixes were submitted independently by J. Grant)
1876 2005-07-30 J. Grant <jg@jguk.org>
1878 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1879 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1880 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1882 2005-07-15 Paul Smith <psmith@gnu.org>
1884 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1885 we don't have a POSIX shell, then revert to the old
1886 backslash-newline behavior (where they are stripped).
1889 2005-07-08 Paul D. Smith <psmith@gnu.org>
1891 * config.h.W32.template: Reorder to match the standard config.h,
1892 for easier comparisons.
1893 From J. Grant <jg@jguk.org>
1895 * maintMakefile: Remove .dep_segment before overwriting it, in
1896 case it's not writable or noclobber is set.
1897 * expand.c (variable_expand_string): Cast result of pointer
1898 arithmetic to avoid a warning.
1899 * main.c (switches): Add full-fledged final initializer.
1901 2005-07-06 Paul D. Smith <psmith@gnu.org>
1903 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1904 * signame.c (strsignal): If we found _sys_siglist[] or
1905 __sys_siglist[] use those instead of sys_siglist[].
1906 From Albert Chin <china@thewrittenword.com>
1908 2005-07-04 Paul D. Smith <psmith@gnu.org>
1910 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1911 globfree(); set up to use the GNU versions.
1912 From Martin Zinser <zinser@zinser.no-ip.info>
1914 2005-07-03 Paul D. Smith <psmith@gnu.org>
1916 From J. Grant <jg@jguk.org>:
1918 * README.W32.template: Update the Windows and tested MSVC versions.
1919 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1920 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1921 * build_w32.bat: Ditto.
1922 * w32/subproc/build.bat: Ditto.
1924 2005-06-28 Paul D. Smith <psmith@gnu.org>
1926 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1927 declaration was checked but not present.
1929 2005-06-27 Paul D. Smith <psmith@gnu.org>
1931 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1932 to unsigned long. Fixes Savannah bug #13550.
1934 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1935 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1936 Fixes Savannah bug #13551.
1938 2005-06-26 Paul D. Smith <psmith@gnu.org>
1940 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1941 it if ANSI_STRING is not set.
1943 2005-06-25 Paul D. Smith <psmith@gnu.org>
1945 * read.c (eval): If no filenames are passed to any of the
1946 "include" variants, don't print an error.
1947 * doc/make.texi (Include): Document this.
1948 Fixes Savannah bug #1761.
1950 * job.c (construct_command_argv_internal): Sanitize handling of
1951 backslash/newline pairs according to POSIX: that is, keep the
1952 backslash-newline in the command script, but remove a following
1953 TAB character, if present. In the fast path, make sure that the
1954 behavior matches what the shell would do both inside and outside
1955 of quotes. In the slow path, quote the backslash and put a
1956 literal newline in the string.
1957 Fixes Savannah bug #1332.
1958 * doc/make.texi (Execution): Document the new behavior and give
1960 * NEWS: Make a note of the new behavior.
1962 * make.h [WINDOWS32]: #include <direct.h>.
1963 Fixes Savannah bug #13478.
1965 * remake.c (name_mtime): If the stat() of a file fails and the -L
1966 option was given and the file is a symlink, take the best mtime of
1967 the symlink we can get as the mtime of the file and don't fail.
1968 Fixes Savannah bug #13280.
1970 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1971 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1972 inside a variable reference. Make this function static as it's
1974 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1975 parsing an unexpanded line looking for semicolons.
1976 Fixes Savannah bug #1454.
1977 * misc.c (remove_comments): Move this to read.c and make it static
1978 as it's only used there. Call find_char_unquote() with new arg.
1979 * make.h: Remove prototypes for find_char_unquote() and
1980 remove_comments() since they're static now.
1982 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1983 its export flag and obtain its value. When we need to re-exec,
1984 increment the value and add it into the environment.
1985 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1986 * NEWS: Mention MAKE_RESTARTS.
1987 * main.c (always_make_set): New variable. Change the -B option to
1988 set this one instead.
1989 (main): When checking makefiles, only set always_make_flag if
1990 always_make_set is set AND the restarts flag is 0. When building
1991 normal targets, set it IFF always_make_set is set.
1992 (main): Avoid infinite recursion with -W, too: only set what-if
1993 files to NEW before we check makefiles if we've never restarted
1994 before. If we have restarted, set what-if files to NEW _after_ we
1996 Fixes Savannah bug #7566:
1998 2005-06-17 Paul D. Smith <psmith@gnu.org>
2000 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2001 in the prerequisites list.
2003 2005-06-12 Paul D. Smith <psmith@gnu.org>
2005 Fix Savannah bug # 1328.
2007 * configure.in: Check for atexit().
2008 * misc.c (close_stdout): Test stdout to see if writes to it have
2009 failed. If so, be sure to exit with a non-0 error code. Based on
2010 code found in gnulib.
2011 * make.h: Prototype.
2012 * main.c (main): Install close_stdout() with atexit().
2014 2005-06-10 Paul D. Smith <psmith@gnu.org>
2016 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2018 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2019 headers; make vmsWaitForChildren() static; extern vmsify().
2020 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2021 Don't create child_execute_job() here (it's in vmsjobs.c).
2022 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2024 2005-06-09 Paul D. Smith <psmith@gnu.org>
2026 * variable.c (push_new_variable_scope): File variables point
2027 directly to the global_setlist variable. So, inserting a new
2028 scope in front of that has no effect on those variables: they
2029 don't go through current_variable_set_list. If we're pushing a
2030 scope and the current scope is global, push it "the other way" so
2031 that the new setlist is in the global_setlist variable, and
2032 next points to a new setlist with the global variable set.
2033 (pop_variable_scope): Properly undo a push with the new
2035 Fixes Savannah bug #11913.
2037 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2039 * job.c (reap_children): Don't die of the command failed but
2040 the dontcare flag is set. Fixes Savannah bug #13216.
2042 * implicit.c (pattern_search): When creating a target from
2043 an implicit rule match, lookup pattern target and set precious
2044 flag in a newly created target. Fixes Savannah bug #13218.
2046 2005-05-13 Paul D. Smith <psmith@gnu.org>
2048 Implement "if... else if... endif" syntax.
2050 * read.c (eval): Push all checks for conditional words ("ifeq",
2051 "else", etc.) down into the conditional_line() function.
2052 (conditional_line): Rework to allow "else if..." clause. New
2053 return value -2 for lines which are not conditionals. The
2054 ignoring flag can now also be 2, which means "already parsed a
2055 true branch". If that value is seen no other branch of this
2056 conditional can be considered true. In the else parsing if there
2057 is extra text after the else, invoke conditional_line()
2058 recursively to see if it's another conditional. If not, it's an
2059 error. If so, raise the conditional value to this level instead
2060 of creating a new conditional nesting level. Special check for
2061 "else" and "endif", which aren't allowed on the "else" line.
2062 * doc/make.texi (Conditional Syntax): Document the new syntax.
2064 2005-05-09 Paul D. Smith <psmith@gnu.org>
2066 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2067 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2068 recurses to the w32 directory, even on non-Windows systems. Use
2069 the method suggested in the automake manual.
2070 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2071 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2073 2005-05-07 Paul D. Smith <psmith@gnu.org>
2075 * main.c (die): If we're dying with a fatal error (not that a
2076 command has failed), write back any leftover tokens before we go.
2078 * job.c (set_child_handler_action_flags): If there are jobs
2079 waiting for the load to go down, set an alarm to go off in 1
2080 second. This allows us to wake up from a potentially long-lasting
2081 read() and start a new job if the load has gone down. Turn it off
2083 (job_noop): Dummy signal handler function.
2084 (new_job): Invoke it with the new semantics.
2086 * docs/make.texi: Document secondary expansion. Various cleanups
2089 2005-05-03 Paul D. Smith <psmith@gnu.org>
2091 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2092 the targets which are to ultimately be made are called "goals";
2093 see the GNU make manual. Also, MAKECMDGOALS, etc.
2095 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2096 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2097 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2099 2005-05-02 Paul D. Smith <psmith@gnu.org>
2101 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2102 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2103 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2104 functions to vmsjobs.c. #include it into jobs.c.
2106 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2107 jobserver tokens. I found that this happens when an exported
2108 recursive variable contains a $(shell ...) function reference: in
2109 this situation we could "forget" to write back a token.
2111 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2112 we have. It's not reliable to depend on the number of children in
2113 our linked list so keep a separate count.
2114 (new_job): Check jobserver_tokens rather than children &&
2115 waiting_jobs. Increment jobserver_tokens when we get one.
2116 (free_child): If jobserver_tokens is 0, internal error. If it's
2117 >1, write a token back to the jobserver pipe (we don't write a
2118 token for the "free" job). Decrement jobserver_tokens.
2120 * main.c: Add variable master_job_slots.
2121 (main): Set it to hold the number of jobs requested if we're the
2122 master process, when using the jobserver.
2123 (die): Sanity checks: first test jobserver_tokens to make sure
2124 this process isn't holding any tokens we didn't write back.
2125 Second, if master_job_slots is set count the tokens left in the
2126 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2128 2005-04-24 Paul D. Smith <psmith@gnu.org>
2130 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2131 with -l# can lose jobserver tokens, because waiting jobs are not
2132 consulted properly when checking for the "free" token.
2134 * job.c (free_child): Count waiting_jobs as having tokens.
2135 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2136 handle jobs waiting for the load to drop.
2138 2005-04-23 Paul D. Smith <psmith@gnu.org>
2140 * main.c (main): Be careful to not core if a variable setting in
2141 the environment doesn't contain an '='. This is illegal but can
2142 happen in broken setups.
2143 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2145 2005-04-12 Paul D. Smith <psmith@gnu.org>
2147 The second expansion feature causes significant slowdown. Timing
2148 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2149 read the makefile before the feature, to 11+s to do the same
2150 operations after the feature. Additionally, memory usage
2151 increased drastically. To fix this I added some intelligence that
2152 avoids the overhead of the second expansion unless it's required.
2154 * dep.h: Add a new boolean field, need_2nd_expansion.
2156 * read.c (eval): When creating the struct dep for the target,
2157 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2158 (record_files): If there's a "%" in a static pattern rule, it gets
2159 converted to "$*" so set need_2nd_expansion to 1.
2161 * file.c (expand_deps): Rework to be more efficient. Only perform
2162 initialize_file_variables(), set_file_variables(), and
2163 variable_expand_for_file() if the need_2nd_expansion is set.
2165 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2166 (pattern_search): Ditto.
2167 * main.c (handle_non_switch_argument): Ditto.
2169 * read.c (read_all_makefiles): Ditto.
2170 (eval_makefile): Ditto.
2172 2005-04-07 Paul D. Smith <psmith@gnu.org>
2174 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2175 * variable.c (sync_Path_environment): Ditto.
2176 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2178 * main.c (main): Define the .FEATURES variable.
2179 * NEWS: Announce .FEATURES.
2180 * doc/make.texi (Special Variables): Document .FEATURES.
2182 * remake.c (check_dep): If a file is .PHONY, update it even if
2183 it's marked intermediate. Fixes Savannah bug #12331.
2185 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2187 * file.c (expand_deps): Factor out the second expansion and
2188 prerequisite line parsing logic from snap_deps().
2190 * file.c (snap_deps): Use expand_deps(). Expand and parse
2191 prerequisites of the .SUFFIXES special target first. Fixes
2192 Savannah bug #12320.
2194 2005-03-13 Paul D. Smith <psmith@gnu.org>
2196 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2199 2005-03-11 Paul D. Smith <psmith@gnu.org>
2201 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2202 available, not undefined (from Earnie Boyd).
2204 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2206 * implicit.c (pattern_search): Mark an intermediate target as
2207 precious if it happened to be a prerequisite of some (other)
2208 target. Fixes Savannah bug #12267.
2210 2005-03-09 Paul D. Smith <psmith@gnu.org>
2212 * read.c (eval_makefile): Add alloca(0).
2213 (eval_buffer): Ditto.
2215 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2217 * main.c (main): Use o_file instead of o_default when defining
2218 the .DEFAULT_TARGET special variable.
2219 * read.c (eval): Use define_variable_global() instead of
2220 define_variable() when setting new value for the .DEFAULT_TARGET
2221 special variable. Fixes Savannah bug #12266.
2223 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2225 * imlicit.c (pattern_search): Mark files for which an implicit
2226 rule has been found as targets. Fixes Savannah bug #12202.
2228 2005-03-04 Paul D. Smith <psmith@gnu.org>
2231 * doc/make.texi (Automatic Variables): Document $|.
2233 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2235 * read.c (record_files): Instead of substituting % with
2236 actual stem value in dependency list replace it with $*.
2237 This fixes stem triple expansion bug.
2239 * implicit.c (pattern_search): Copy stem to a separate
2240 buffer and make it a properly terminated string. Assign
2241 this buffer instead of STEM (which is not terminated) to
2242 f->stem. Instead of substituting % with actual stem value
2243 in dependency list replace it with $*. This fixes stem
2244 triple expansion bug.
2246 2005-03-01 Paul D. Smith <psmith@gnu.org>
2248 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2249 on Windows, as it takes a handle not a pid. Just exit.
2250 Fix from patch #3679, provided by Alessandro Vesely.
2252 * configure.in: Update check for sys_siglist[] from autoconf manual.
2253 * signame.c (strsignal): Update to use the new autoconf macro.
2255 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2257 * read.c (record_files): Add a check for the list of prerequisites
2258 of a static pattern rule being empty. Fixes Savannah bug #12180.
2260 2005-02-28 Paul D. Smith <psmith@gnu.org>
2262 * doc/make.texi (Text Functions): Update docs to allow the end
2263 ordinal for $(wordlist ...) to be 0.
2264 * function.c (func_wordlist): Fail if the start ordinal for
2265 $(wordlist ...) is <1. Matches documentation.
2266 Resolves Savannah support request #103195.
2268 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2269 previously we were stopping when !-q, exactly the opposite. This
2270 has been wrong since version 1.34, in 1994!
2271 (update_file): If we got an error don't break out to run more
2272 double-colon rules: just return immediately.
2273 Fixes Savannah bug #7144.
2275 2005-02-27 Paul D. Smith <psmith@gnu.org>
2277 * misc.c (end_of_token): Make argument const.
2278 * make.h: Update prototype.
2280 * function.c (abspath, func_realpath, func_abspath): Use
2281 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2282 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2283 * read.c (record_files): Ditto.
2284 * variable.c (do_variable_definition): Ditto.
2286 * function.c (func_error): Create a new function $(info ...) that
2287 simply prints the message to stdout with no extras.
2288 (function_table_init): Add new function to the table.
2289 * NEWS: Add $(info ...) reference.
2290 * doc/make.texi (Make Control Functions): Document it.
2292 New feature: if the system supports symbolic links, and the user
2293 provides the -L/--check-symlink-time flag, then use the latest
2294 mtime between the symlink(s) and the target file.
2296 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2297 readlink(). If both are available, define MAKE_SYMLINKS.
2298 * main.c: New variable: check_symlink_flag.
2299 (usage): Add a line for -L/--check-symlink-times to the help string.
2300 (switches): Add -L/--check-symlink-times command line argument.
2301 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2302 print a warning and disable it again.
2303 * make.h: Declare check_symlink_flag.
2304 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2305 if the file is a symlink then check each link in the chain and
2306 choose the NEWEST mtime we find as the mtime for the file. The
2307 newest mtime might be the file itself!
2308 * NEWS: Add information about this new feature.
2309 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2311 Avoid core dumps described in Savannah bug # 12124:
2313 * file.c: New variable snapped_deps remember whether we've run
2315 (snap_deps): Set it.
2316 * filedef.h: Extern it.
2317 * read.c (record_files): Check snapped_deps; if it's set then
2318 we're trying to eval a new target/prerequisite relationship from
2319 within a command script, which we don't support. Fatal.
2321 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2323 Implementation of the .DEFAULT_TARGET special variable.
2325 * read.c (eval): If necessary, update default_target_name when
2327 * read.c (record_files): Update default_target_file if
2328 default_target_name has changed.
2329 * main.c (default_target_name): Define.
2330 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2331 default_target_name is set use default_target_file as a root
2333 * filedef.h (default_target_name): Declare.
2334 * dep.h (free_dep_chain):
2335 * misc.c (free_dep_chain): Change to operate on struct nameseq
2336 and change name to free_ns_chain.
2337 * file.c (snap_deps): Update to use free_ns_chain.
2339 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2341 Implementation of the second expansion in explicit rules,
2342 static pattern rules and implicit rules.
2344 * read.c (eval): Refrain from chopping up rule's dependencies.
2345 Store them in a struct dep as a single dependency line. Remove
2346 the code that implements SySV-style automatic variables.
2348 * read.c (record_files): Adjust the code that handles static
2349 pattern rules to expand all percents instead of only the first
2350 one. Reverse the order in which dependencies are stored so that
2351 when the second expansion reverses them again they appear in
2352 the makefile order (with some exceptions, see comments in
2353 the code). Remove the code that implements SySV-style automatic
2356 * file.c (snap_deps): Implement the second expansion and chopping
2357 of dependency lines for explicit rules.
2359 * implicit.c (struct idep): Define an auxiliary data type to hold
2360 implicit rule's dependencies after stem substitution and
2363 * implicit.c (free_idep_chain): Implement.
2365 * implicit.c (get_next_word): Implement helper function for
2366 parsing implicit rule's dependency lines into words taking
2367 into account variable expansion requests. Used in the stem
2370 * implicit.c (pattern_search): Implement the second expansion
2371 for implicit rules. Also fixes bug #12091.
2373 * commands.h (set_file_variables): Declare.
2374 * commands.c (set_file_variables): Remove static specifier.
2376 * dep.h (free_dep_chain): Declare.
2377 * misc.c (free_dep_chain): Implement.
2379 * variable.h (variable_expand_for_file): Declare.
2380 * expand.c (variable_expand_for_file): Remove static specifier.
2382 * make.h (strip_whitespace): Declare.
2383 * function.c (strip_whitespace): Remove static specifier.
2385 2005-02-26 Paul D. Smith <psmith@gnu.org>
2387 * main.c (main): Check for ferror() when reading makefiles from stdin.
2388 Apparently some shells in Windows don't close pipes properly and
2391 2005-02-24 Jonathan Grant <jg@jguk.org>
2393 * configure.in: Add MinGW configuration options, and extra w32 code
2395 * Makefile.am: Add MinGW configuration options, and extra w32 code
2397 * main.c: Determine correct program string (after last \ without .exe).
2398 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2400 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2401 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2402 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2403 environment support.
2405 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2407 * function.c (func_shell): When initializing error_prefix, check
2408 that reading file name is not null. This fixes long-standing
2409 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2411 2005-02-09 Paul D. Smith <psmith@gnu.org>
2413 * maintMakefile: Update the CVS download URL to simplify them.
2414 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2415 downloading the .texi files from Savannah now.
2417 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2419 * main.c (handle_non_switch_argument): Only add variables to
2420 command_variables if they're not already there: duplicate settings
2421 waste space and can be confusing to read.
2423 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2424 this header is never included by non-WINDOWS32 code, and it
2425 requires <config.h> to define which isn't always included first.
2427 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2428 testing MINGW32 versions.
2430 * main.c (log_working_directory): flush stdout to be sure the WD
2431 change is printed before any stderr messages show up.
2433 2005-02-01 Paul D. Smith <psmith@gnu.org>
2435 * maintMakefile (po_repo): Update the GNU translation site URL.
2437 2004-12-01 Paul D. Smith <psmith@gnu.org>
2439 * main.c (main): Change char* env_shell to struct variable shell_var.
2440 * variable.c (target_environment): Use new shell_var.
2442 2004-11-30 Paul D. Smith <psmith@gnu.org>
2444 * configure.in: The old way we avoided creating build.sh from
2445 build.sh.in before build.sh.in exists doesn't work anymore; we
2446 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2447 the help!). This also keeps automake from complaining.
2448 * Makefile.am (README): Add a dummy target so automake won't
2449 complain that this file doesn't exist when we checkout from CVS.
2450 * maintMakefile (.dep_segment): Rewrite this rule since newer
2451 versions of automake don't provide DEP_FILES.
2453 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2455 Implementation of `realpath' and `abspath' built-in functions.
2457 * configure.in: Check for realpath.
2458 * function.c (abspath): Return an absolute file name that does
2459 not contain any `.' or `..' components, nor repeated `/'.
2460 * function.c (func_abspath): For each name call abspath.
2461 * function.c (func_realpath): For each name call realpath
2462 from libc or delegate to abspath if realpath is not available.
2463 * doc/make.texi (Functions for File Names): Document new functions.
2464 * doc/make.texi (Quick Reference): Ditto.
2466 2004-11-28 Paul D. Smith <psmith@gnu.org>
2468 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2469 arguments. Fixes bug #10252.
2471 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2473 * main.c (main): Set SHELL to v_noexport by default. Remember the
2474 original environment setting of SHELL in the env_shell variable.
2475 * main.h: Export new env_shell variable.
2476 * variable.c (target_environment): If we find a v_noexport
2477 variable for SHELL, add a SHELL variable with the env_shell value.
2478 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2479 * doc/make.texi (Variables/Recursion): Ditto.
2481 2004-11-28 Paul D. Smith <psmith@gnu.org>
2483 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2484 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2485 Patch by Alessandro Vesely.
2487 2004-11-12 Paul D. Smith <psmith@gnu.org>
2489 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2490 the command line if it's inside a string.
2491 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2493 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2495 * function.c (func_lastword): New function: return last word
2496 from the list of words.
2497 * doc/make.texi: Document $(lastword ). Fix broken links in
2498 Quick Reference section.
2500 2004-10-06 Paul D. Smith <psmith@gnu.org>
2502 Apply patch from Alessandro Vesely, provided with bug # 9748.
2503 Fix use of tmpnam() to work with Borland C.
2505 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2506 construction of a temporary filename, and call new function
2507 create_batch_filename().
2508 (create_batch_filename) [WINDOWS32]: New function to create a
2511 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2513 * read.c (record_target_var): Expand simple pattern-specific
2515 * variable.c (initialize_file_variables): Do not expand simple
2516 pattern-specific variable.
2518 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2520 * remake.c (update_file_1): When rebuilding makefiles inherit
2521 dontcare flag from a target that triggered update.
2523 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2525 * variable.c (initialize_file_variables): Mark pattern-specific
2526 variable as a per-target and copy export status.
2528 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2530 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2532 * implicit.c (pattern_search): When considering an implicit rule's
2533 prerequisite check that it is actually a target rather then
2534 just an entry in the file hashtable.
2536 2004-09-21 Paul D. Smith <psmith@gnu.org>
2538 * read.c (readstring): Fix some logic errors in backslash handling.
2539 (eval): Remove some unnecessary processing in buffer handling.
2540 (record_target_var): Assert that parse_variable_definition() succeeded.
2541 Reported by: Markus Mauhart <qwe123@chello.at>.
2543 * misc.c: Removed the sindex() function. All instances of this
2544 function were trivially replaceable by the standard strstr()
2545 function, and that function will always have better (or certainly
2546 no worse) performance than the very simple-minded algorithm
2547 sindex() used. This can matter with complex makefiles.
2548 * make.h: Remove the prototype for sindex().
2549 * function.c (subst_expand): Convert sindex() call to strstr().
2550 This means we no longer need to track the TLEN value so remove that.
2551 (func_findstring): Convert sindex() to strstr().
2552 * commands.c (chop_commands): Convert sindex() calls to strstr().
2553 Suggested by: Markus Mauhart <qwe123@chello.at>.
2555 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2556 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2557 If SHELL is set to CMD.EXE then assume it's batch-mode and
2558 non-unixy. I wrote the code differently from the patch, though,
2559 to make it safer. This also resolves bug #9174.
2561 2004-09-20 Paul D. Smith <psmith@gnu.org>
2563 * expand.c (variable_expand_string): Modify to invoke
2564 patsubst_expand() instead of subst_expand(); the latter didn't
2565 handle suffix patterns correctly.
2566 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2567 was used only from variable_expand_string() and is no longer used
2569 (func_subst): Ditto, on call to subst_expand().
2570 (patsubst_expand): Require the percent pointers to point to the
2571 character after the %, not to the % itself.
2572 * read.c (record_files): New call criteria for patsubst_expand().
2573 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2574 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2576 2004-09-19 Paul D. Smith <psmith@gnu.org>
2578 * function.c (subst_expand): Fix a check in by_word: look for a
2579 previous blank if we're beyond the beginning of the string, not
2580 the beginning of the word.
2581 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2583 2004-05-16 Paul D. Smith <psmith@gnu.org>
2585 * remake.c (update_goal_chain): Change the argument specifying
2586 whether we're rebuilding makefiles to be a global variable,
2587 REBUILDING_MAKEFILES.
2588 (complain): Extract the code that complains about no rules to make
2589 a target into a separate function.
2590 (update_file_1): If we tried to rebuild a file during the makefile
2591 rebuild phase and it was dontcare, then no message was printed.
2592 If we then try to build the same file during the normal build,
2593 print a message this time.
2594 (remake_file): Don't complain about un-remake-able files when
2595 we're rebuilding makefiles.
2597 2004-05-11 Paul D. Smith <psmith@gnu.org>
2599 * job.c (construct_command_argv_internal): OS/2 patches from
2600 Andreas Buening <andreas.buening@nexgo.de>.
2602 2004-05-10 Paul D. Smith <psmith@gnu.org>
2604 * remake.c (update_file): Don't walk the double-colon chain unless
2605 this is a double-colon rule. Fix suggested by Boris Kolpackov
2606 <boris@kolpackov.net>.
2608 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2609 * readme.vms: New section describing OpenVMS support and issues.
2610 * default.c (default_variables): Add support for IA64.
2611 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2612 without some privilege aborts make with the error
2613 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2614 pressing Ctrl+Y and the input device is no terminal. The change
2615 catches this error and just continues.
2617 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2619 2004-04-25 Paul D. Smith <psmith@gnu.org>
2621 * commands.c (set_file_variables): Set $< properly in the face of
2622 order-only prerequisites.
2623 Patch from Boris Kolpackov <boris@kolpackov.net>
2625 2004-04-21 Bob Byrnes <byrnes@curl.com>
2627 * main.c (main): Notice failures to remake makefiles.
2629 2004-03-28 Paul D. Smith <psmith@gnu.org>
2631 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2633 * job.c: No default shell for RISC OS.
2634 (load_too_high): Hard-code the return to 1.
2635 (construct_command_argv_internal): No sh_chars or sh_cmds.
2636 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2638 2004-03-20 Paul D. Smith <psmith@gnu.org>
2640 * variable.c (do_variable_definition): Don't append from the
2641 global set if a previous non-appending target-specific variable
2642 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2645 * expand.c (reference_variable): Don't give up on variables with
2646 no value that have the target-specific append flag set: they might
2647 have a value after all. Reported by Oliver Schmidt
2648 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2649 <nikulin@dx1cmd.inp.nsk.su>.
2651 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2652 refer to absolute pathnames in directories that don't exist: some
2653 portion of the makefile could create those directories before we
2654 match the pattern. Fixes bugs #775 and #108.
2656 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2658 * main.c (main): Free makefile_mtimes if we have any.
2659 * README.W32.template: Update documentation for the current status
2660 of the MS-Windows port.
2661 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2662 environment variable is sometimes already defined which causes the
2664 * main.c (debug_signal_handler): Only define this function if
2665 SIGUSR1 is available.
2667 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2669 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2670 * README.OS2.template: Documentation updates.
2671 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2672 link line for safety.
2673 * maintMakefile (build.sh.in): Remove an extraneous ")".
2674 * job.c (child_execute_job): Close saved FDs.
2675 * job.c (exec_command) [OS/2]: exec_command(): If the command
2676 can't be exec'ed and if the shell is not Unix-sh, then try again
2677 with argv = { "cmd", "/c", ... }. Normally, this code is never
2678 reached for the cmd shell unless the command really doesn't exist.
2679 (construct_command_argv_internal) [OS/2]: The code for cmd
2680 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2681 The CMD builtin commands are case insensitive so use strcasecmp().
2683 2004-03-19 Paul D. Smith <psmith@gnu.org>
2685 * read.c (do_define): Re-order line counter increment so the count
2686 is accurate (we were losing one line per define). Reported by
2687 Dave Yost <Dave@Yost.com>.
2689 2004-03-06 Paul D. Smith <psmith@gnu.org>
2691 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2693 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2694 * misc.c (message,error,fatal): Ditto.
2695 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2696 * config.h.W32.template: Ditto.
2697 * config.h-vms.template: Ditto.
2698 * config.ami.template: Ditto.
2700 2004-03-04 Paul D. Smith <psmith@gnu.org>
2702 * README.template: Add a note about broken /bin/sh on SunOS
2703 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2705 * misc.c (message, error, fatal): Don't use "..." if we're using
2706 varargs. ansi2knr should handle this but it doesn't work: it
2707 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2708 done. On many systems (SunOS for example) va_dcl is a #define.
2709 So, force the use of the non-"..." version on pre-ANSI compilers.
2711 * maintMakefile (sign-dist): Create some rules to help automate
2712 the new GNU ftp upload method.
2714 2004-02-24 Paul D. Smith <psmith@gnu.org>
2716 * config.h.W32.template: Add HAVE_STDARG_H
2717 * config.h-vms.template: Ditto.
2718 * config.ami.template: Ditto.
2720 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2722 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2723 * build_w32.bat: Remove extra "+".
2725 2004-02-23 Paul D. Smith <psmith@gnu.org>
2727 * make.h: Create an UNUSED macro to mark unused parameters.
2728 * (many): Clean up warnings by applying UNUSED, fixing
2729 signed/unsigned incompatibilities, etc.
2731 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2733 * filedef.h: Name the command_state enumeration.
2734 * file.c (set_command_state): Use the enumeration in the function
2737 * configure.in: Explicitly set SET_MAKE to empty, to disable
2738 MAKE=make even when no make already exists. Fix bug #3823.
2740 2004-02-22 Paul D. Smith <psmith@gnu.org>
2742 * maintMakefile: Perl script to clean up all non-CVS files. Use
2743 it on all the subdirectories for the cvs-clean target.
2745 * main.c (decode_switches): Require non-empty strings for all our
2746 string command-line options. Fixes Debian bug # 164165.
2748 * configure.in: Check for stdarg.h and varargs.h.
2749 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2750 for printing messages.
2751 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2756 A number of patches for OS/2 support from Andreas Buening
2757 <andreas.buening@nexgo.de>:
2759 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2760 disable the SIGCHLD handler.
2761 (reap_children) [OS/2]: Remove special handling of job_rfd.
2762 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2763 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2764 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2765 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2766 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2769 2004-02-21 Paul D. Smith <psmith@gnu.org>
2771 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2772 <mail@kristov.de> reports that if process_begin() fails we don't
2773 handle the error condition correctly in all cases.
2774 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2775 to have a newline on the message.
2777 * job.c (construct_command_argv_internal): Add "test" to UNIX
2778 sh_cmds[]. Fixes Savannah bug # 7606.
2780 2004-02-04 Paul D. Smith <psmith@gnu.org>
2782 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2783 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2784 Hartmut Becker <Hartmut.Becker@hp.com>.
2786 2004-01-21 Paul D. Smith <psmith@gnu.org>
2788 * job.c (load_too_high): Implement an algorithm to control the
2789 "thundering herd" problem when using -l to control job creation
2790 via the load average. The system only recomputes the load once a
2791 second but we can start many jobs in a second. To solve this we
2792 keep track of the number of jobs started in the last second and
2793 apply a weight to try to guess what a correct load would be.
2794 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2795 Also fixes bug #4693.
2796 (reap_children): Decrease the job count for this second.
2797 (start_job_command): Increase the job count for this second.
2799 * read.c (conditional_line): Expand the text after ifn?def before
2800 checking to see if it's a single word. Fixes bug #7257.
2802 2004-01-09 Paul D. Smith <psmith@gnu.org>
2804 * file.c (print_file): Recurse to print all targets in
2805 double-colon rules. Fixes bug #4518, reported (with patch) by
2806 Andrew Chatham <chatham@google.com>.
2808 2004-01-07 Paul D. Smith <psmith@gnu.org>
2810 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2811 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2812 AC_FUNC_SETVBUF_REVERSED.
2814 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2815 (MAKE Variable): Fix Savannah bug #4898.
2817 * job.c (construct_command_argv_internal): Add "!" to the list of
2818 shell escape chars. POSIX sh allows it to appear before a
2819 command, to negate the exit code. Fixes bug #6404.
2821 * implicit.c (pattern_search): When matching an implicit rule,
2822 remember which dependencies have the ignore_mtime flag set.
2823 Original fix provided in Savannah patch #2349, by Benoit
2824 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2826 2003-11-22 Paul D. Smith <psmith@gnu.org>
2828 * README.W32.template (Outputs): Clarification on -j with
2829 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2832 2003-11-02 Paul D. Smith <psmith@gnu.org>
2834 * function.c (func_if): Strip all the trailing whitespace from the
2835 condition, then don't expand it. Fixed bug # 5798.
2837 * expand.c (recursively_expand_for_file): If we're expanding a
2838 variable with no file context, then use the variable's context.
2841 2003-10-21 Paul D. Smith <psmith@gnu.org>
2843 * main.c (log_working_directory): Add newlines to printf()s.
2845 * README.cvs: Add a note to ignore warnings during autoreconf.
2847 * maintMakefile (po_repo): Set a new URL for PO file updates.
2848 (get-config/config.guess get-config/config.sub): Get these files
2849 from the Savannah config project instead of ftp.gnu.org.
2851 2003-10-05 Paul Eggert <eggert@twinsun.com>
2853 * main.c (main): Avoid potential subscript error if environ has
2856 2003-08-22 Paul D. Smith <psmith@gnu.org>
2858 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2859 systems which don't yet implement the C89 standard :-/.
2861 2003-07-18 Paul D. Smith <psmith@gnu.org>
2863 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2864 [WINDOWS32]: Initialize hash.
2866 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2868 * dir.c (read_dirstream): Provide a workaround for broken versions of
2869 the MinGW dirent structure.
2871 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2873 * w32/include/dirent.h: Add __MINGW32__ filter.
2875 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2877 * make.h: Add global declaration of *make_host.
2878 * main.c (print_usage): Remove local declaration of *make_host.
2879 (print_version): Display "This program built for ..." after Copyright
2882 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2884 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2885 execution of "makeinfo --html make.texi".
2887 2003-04-30 Paul D. Smith <psmith@gnu.org>
2889 * build.template: Make some changes to maybe allow this script to
2890 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2892 * README.OS2.template: New file for OS/2 support. Original
2893 contributed by Andreas Buening.
2894 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2897 2003-04-19 Paul D. Smith <psmith@gnu.org>
2899 Fix bug #1405: allow a target to match multiple pattern-specific
2902 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2903 variable.c, where they've always belonged.
2904 * rule.h: Move the prototypes and struct pattern_var as well.
2905 * variable.c (initialize_file_variables): Invoke
2906 lookup_pattern_var() in a loop, until no more matches are found.
2907 If a match is found, create a new variable set for the target's
2908 pattern variables. Then merge the contents of each matching
2909 pattern variable set into the target's pattern variable set.
2910 (lookup_pattern_var): Change this function to be usable
2911 in a loop. It takes a starting position: if NULL, start at the
2912 beginning; if non-NULL, start with the pattern variable after that
2913 position, and return the next matching pattern.
2914 (create_pattern_var): Create a unique instance of
2915 pattern-specific variables for every definition in the makefile.
2916 Don't combine the same pattern together. This allows us to
2917 process the variable handling properly even when the same pattern
2918 is used multiple times.
2919 (parse_variable_definition): New function: break out the parsing
2920 of a variable definition line from try_variable_definition.
2921 (try_variable_definition): Call parse_variable_definition to
2923 (print_variable_data_base): Print out pattern-specific variables.
2924 * variable.h (struct variable): Remember when a variable is
2925 conditional. Also remember its flavor.
2926 (struct pattern_var): Instead of keeping a variable set, we just
2927 keep a single variable for each pattern.
2928 * read.c (record_target_var): Each pattern variable contains only a
2929 single variable, not a set, so create it properly.
2930 * doc/make.texi (Pattern-specific): Document the new behavior.
2932 2003-04-17 Paul D. Smith <psmith@gnu.org>
2934 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2935 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2936 file/directory naming rules for VMS so I can't tell whether this
2939 2003-04-09 Paul D. Smith <psmith@gnu.org>
2941 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2942 DOS-style pathnames: backslash separators and drive specifiers.
2944 2003-03-28 Paul D. Smith <psmith@gnu.org>
2946 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2947 the intermediate flag on all targets. Fixes bug #2515.
2949 2003-03-24 Paul D. Smith <psmith@gnu.org>
2951 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2952 Upgrade to autoconf 2.57 and automake 1.7.3.
2954 * job.c: More OS/2 changes from Andreas Buening.
2956 * file.c (print_file): Fix variable initialization.
2959 * remake.c (notice_finished_file):
2961 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2962 some calls (like readdir()) return NULL in valid situations
2963 without resetting errno. Fixes bug #2846.
2965 2003-02-25 Paul D. Smith <psmith@gnu.org>
2967 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2969 * job.c (_is_unixy_shell) [OS/2]: New function.
2970 Set default shell to /bin/sh.
2971 (reap_children): Close the job_rfd pipe here since we don't use a
2973 (set_child_handler_action_flags): define this to empty on OS/2.
2974 (start_job_command): Close the jobserver pipe and use
2975 child_execute_job() instead of fork/exec.
2976 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2977 rather than exec'ing, then reconfigure stdin/stdout.
2978 (exec_command): Rewrite to use spawn instead of exec. Return the
2981 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2982 in DOS. Handle the TEMP environment variable as in DOS. Don't
2983 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2984 use -j in DOS mode. Use child_execute_job() instead of
2987 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2990 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2991 prototypes that return values.
2993 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2995 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2996 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2998 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3001 2003-02-24 Paul D. Smith <psmith@gnu.org>
3003 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3004 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3005 (child_execute_job) [VMS]: Handle error status properly.
3006 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3008 * function.c (func_shell): Use EINTRLOOP() while reading from the
3009 subshell pipe (Fixes bug #2502).
3010 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3012 * main.c (main): Ditto.
3014 2003-01-30 Paul D. Smith <psmith@gnu.org>
3016 * read.c (eval): eval() was not fully reentrant, because the
3017 collapsed buffer was static. Change it to be an automatic
3018 variable so that eval() can be invoked recursively.
3020 (eval): Apply patch # 1022: fix memory reference error on long
3021 target-specific variable lines.
3022 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3024 * function.c (check_numeric): Combine the is_numeric() function
3025 into this function, since it's only called from one place.
3026 Constify this function. Have it print the incorrect string in the
3027 error message. Fixes bug #2407.
3028 (strip_whitespace): Constify.
3029 (func_if): Constify.
3030 * expand.c (expand_argument): Constify.
3032 2003-01-29 Paul D. Smith <psmith@gnu.org>
3034 Fix bug # 2169, also reported by other people on various systems.
3036 * make.h: Some systems, such as Solaris and PTX, do not fully
3037 implement POSIX-compliant SA_RESTART functionality; important
3038 system calls like stat() and readdir() can still fail with EINTR
3039 even if SA_RESTART has been set on the signal handler. So,
3040 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3041 EINTR for system calls which return -1 or 0 (NULL), respectively,
3043 Also, remove the old atomic_stat()/atomic_readdir() and
3044 HAVE_BROKEN_RESTART handling.
3046 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3048 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3049 * remake.c (touch_file): Ditto.
3051 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3052 * read.c (construct_include_path): Ditto.
3053 * remake.c (name_mtime): Ditto.
3054 * vpath.c (selective_vpath_search): Ditto.
3055 * dir.c (find_directory): Ditto.
3056 (local_stat): Ditto.
3057 (find_directory): Use ENULLLOOP() to wrap opendir().
3058 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3060 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3061 atomic_readdir() handling.
3063 2003-01-22 Paul D. Smith <psmith@gnu.org>
3065 * function.c (func_call): Fix Bug #1744. If we're inside a
3066 recursive invocation of $(call ...), mask any of the outer
3067 invocation's arguments that aren't used by this one, so that this
3068 invocation doesn't "inherit" them accidentally.
3070 2002-12-05 Paul D. Smith <psmith@gnu.org>
3072 * function.c (subst_expand): Valery Khamenia reported a
3073 pathological performance hit when doing substitutions on very
3074 large values with lots of words: turns out we were invoking
3075 strlen() a ridiculous number of times. Instead of having each
3076 call to sindex() call strlen() again, keep track of how much of
3077 the text we've seen and pass the length to sindex().
3079 2002-11-19 Paul D. Smith <psmith@gnu.org>
3081 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3084 2002-11-16 Paul D. Smith <psmith@gnu.org>
3086 * NMakefile.template (OBJS): Add hash.c object file.
3087 * SMakefile.template (srcs): Ditto.
3088 * Makefile.ami (objs): Ditto.
3089 * build_w32.bat: Ditto.
3091 * Makefile.DOS.template: Remove extra dependencies.
3093 2002-10-25 Paul D. Smith <psmith@gnu.org>
3095 * expand.c (install_variable_buffer): New function. Install a new
3096 variable_buffer context and return the previous one.
3097 (restore_variable_buffer): New function. Free the current
3098 variable_buffer context and put a previously saved one back.
3099 * variable.h: Prototypes for {install,restore}_variable_buffer.
3100 * function.c (func_eval): Push a new variable_buffer context
3101 before we eval, then restore the old one when we're done.
3104 * read.c (install_conditionals): New function. Install a new
3105 conditional context and return the previous one.
3106 (restore_conditionals): New function. Free the current
3107 conditional context and put a previously saved one back.
3108 (eval): Use the {install,restore}_conditionals for "include"
3110 (eval_buffer): Use {install,restore}_conditionals to preserve the
3111 present conditional state before we evaluate the buffer.
3114 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3116 (Recursion): Add a variable index entry for CURDIR.
3118 * README.cvs: Update to appropriate versions.
3119 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3120 don't need to copy loadavg.c: automake is smart enough to create
3121 it for me. Still have a bug in automake related to ansi2knr tho.
3123 2002-10-14 Paul D. Smith <psmith@gnu.org>
3125 * remake.c (notice_finished_file): Only touch targets if they have
3126 at least one command (as per POSIX). Resolve Bug #1418.
3128 * *.c: Convert to using ANSI C-style function definitions.
3129 * Makefile.am: Enable the ansi2knr feature of automake.
3130 * configure.in: ditto.
3132 2002-10-13 Paul D. Smith <psmith@gnu.org>
3134 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3135 for automatic variable values like $^, etc. In the case of very
3136 large lists of prerequisites this causes problems. Instead reuse
3137 a static buffer (resizeable) for each variable.
3139 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3140 target-specific variable definitions. Check for it and set an
3142 (record_target_var): Set the export field to v_export if the
3143 "exported" flag is set.
3144 * doc/make.texi (Target-specific): Document the ability to use
3147 * doc/make.texi: Change the name of the section on automatic
3148 variables from "Automatic" to "Automatic Variables". Added text
3149 clarifying the scope of automatic variables.
3151 2002-10-04 Paul D. Smith <psmith@gnu.org>
3153 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3155 (record_files): Ditto.
3157 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3158 the search for the '=' to only within the enclosing parens.
3160 2002-10-03 Paul D. Smith <psmith@gnu.org>
3162 Version 3.80 released.
3164 * dir.c: Change hash functions to use K&R function definition style.
3165 * function.c: Ditto.
3167 * variable.c: Ditto.
3169 Update to automake 1.7.
3171 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3172 (pdf): Remove this target as automake now provides one.
3174 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3176 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3178 * makefile.com: Updates for GNU make 3.80.
3179 * makefile.vms: Ditto.
3181 2002-09-23 Paul D. Smith <psmith@gnu.org>
3183 * read.c (enum make_word_type): Remove w_comment.
3184 (get_next_mword): Don't treat comment characters as special; where
3185 this function is used we will never see a comment (it's stripped
3186 before we get here) and treating comments specially means that
3187 targets like "foo\#bar" aren't handled properly.
3189 2002-09-18 Paul D. Smith <psmith@gnu.org>
3191 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3193 * read.c (eval): Expansion of arguments to export/unexport was
3194 ignoring all arguments after the first one. Change the algorithm
3195 to expand the whole line once, then parse the results.
3197 2002-09-17 Paul D. Smith <psmith@gnu.org>
3199 Fix Bug #940 (plus another bug I found while looking at this):
3201 * read.c (record_target_var): enter_file() will add a new entry if
3202 it's a double-colon target: we don't want to do that in this
3203 situation. Invoke lookup_file() and only enter_file() if it does
3204 not already exist. If the file we get back is a double-colon then
3205 add this variable to the "root" double-colon target.
3207 * variable.c (initialize_file_variables): If this file is a
3208 double-colon target but is not the "root" target, then initialize
3209 the root and make the root's variable list the parent of our
3212 2002-09-13 Paul D. Smith <psmith@gnu.org>
3214 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3216 * hash.c (round_up_2): Get rid of a warning.
3218 2002-09-12 Paul D. Smith <psmith@gnu.org>
3220 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3221 so it doesn't complain about getloadavg.c.
3223 * commands.c (set_file_variables): Make sure we always alloca() at
3224 least 1 character for the value of $? (for '\0').
3226 2002-09-11 Paul D. Smith <psmith@gnu.org>
3228 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3229 macro to use RESULT instead of the incorrect _RESULT_.
3231 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3232 and atomic_readdir(). We need to #include dirent.h to get this to
3234 * misc.c (atomic_readdir): Fix typos.
3236 2002-09-10 Paul D. Smith <psmith@gnu.org>
3238 * read.c (eval): Expand variable lists given to export and
3239 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3240 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3242 * doc/make.texi (Variables/Recursion): Document this.
3243 (Conditional Syntax): And here.
3245 2002-09-09 Paul D. Smith <psmith@gnu.org>
3247 * configure.in: Check for memmove().
3249 2002-09-07 Paul D. Smith <psmith@gnu.org>
3251 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3252 Michael Sterrett <msterret@coat.com> reports that while it has
3253 SA_RESTART, it does not work properly.
3255 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3256 that invokes stat() and loops to do it again if it returns EINTR.
3257 (atomic_readdir): Ditto, with readdir().
3259 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3260 and readdir() to atomic_stat() and atomic_readdir().
3262 2002-09-04 Paul D. Smith <psmith@gnu.org>
3264 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3265 reports that GNU make sometimes doesn't recognize that targets can
3266 be made, when directories can be created as prerequisites. He
3267 reports that changing the order of predicates in the DEP->changed
3268 flag test so that lookup_file() is always performed, solves this
3271 2002-08-08 Paul D. Smith <psmith@gnu.org>
3273 * configure.in: Require a newer version of gettext.
3275 * misc.c (perror_with_name): Translate the format string (for
3276 right-to-left language support).
3277 (pfatal_with_name): Ditto.
3279 * main.c: Create a static array of strings to store the usage
3280 text. This is done to facilitate translations.
3281 (struct command_switch): Remove argdesc and description fields.
3282 (switches): Remove values for obsolete fields.
3283 (print_usage): Print each element of the usage array.
3285 * hash.c: Change function definitions to be K&R style.
3287 2002-08-02 Paul D. Smith <psmith@gnu.org>
3289 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3290 this one because it's too hard to get right. We'll look at it for
3292 * main.c (main): Don't create the .TARGETS variable.
3293 * variable.c (handle_special_var): Don't handle .TARGETS.
3295 2002-08-01 Paul D. Smith <psmith@gnu.org>
3297 * main.c (switches): Add a new option, -B (--always-make). If
3298 specified, make will rebuild all targets that it encounters even
3299 if they don't appear to be out of date.
3300 (always_make_flag): New flag.
3301 * make.h: Extern always_make_flag.
3302 * remake.c (update_file_1): Check always_make_flag; if it's set we
3303 will always rebuild any target we can, even if none of its
3304 prerequisites are newer.
3307 * doc/make.texi (Shell Function): Make it clear that make
3308 variables marked as "export" are not passed to instances of the
3311 Add new introspection variable .VARIABLES and .TARGETS.
3313 * variable.c (handle_special_var): New function. If the variable
3314 reference passed in is "special" (.VARIABLES or .TARGETS),
3315 calculate the new value if necessary. .VARIABLES is handled here:
3316 walk through the hash of defined variables and construct a value
3317 which is a list of the names. .TARGETS is handled by
3318 build_target_list().
3319 (lookup_variable): Invoke handle_special_var().
3320 * file.c (build_target_list): Walk through the hask of known files
3321 and construct a list of the names of all the ones marked as
3323 * main.c (main): Initialize them to empty (and as simple variables).
3324 * doc/make.texi (Special Variables): Document them.
3325 * NEWS: Mention them.
3327 * variable.h (struct variable): Add a new flag "exportable" which
3328 is true if the variable name is valid for export.
3329 * variable.c (define_variable_in_set): Set "exportable" when a new
3330 variable is defined.
3331 (target_environment): Use the "exportable" flag instead of
3332 re-checking the name here... an efficiency improvement.
3334 2002-07-31 Paul D. Smith <psmith@gnu.org>
3336 * config.h-vms.template: Updates to build on VMS. Thanks to
3337 Brian_Benning@aksteel.com for helping verify the build.
3338 * makefile.com: Build the new hash.c file.
3339 * hash.h: Use strcpmi(), not stricmp(), in the
3340 HAVE_CASE_INSENSITIVE_FS case.
3342 2002-07-30 Paul D. Smith <psmith@gnu.org>
3344 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3345 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3346 Reported by <Brian_Benning@aksteel.com>.
3348 2002-07-10 Paul D. Smith <psmith@gnu.org>
3350 * variable.c (pop_variable_scope): Remove variable made unused by
3351 new hash infrastructure.
3352 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3353 comparisons as well as name comparisons.
3354 * variable.h: Add a prototype for new hash_init_function_table().
3355 * file.c (lookup_file): Remove variables made unused by new hash
3357 * dir.c (directory_contents_hash_2): Missing return of hash value.
3358 (dir_contents_file_exists_p): Remove variables made unused by new
3359 hash infrastructure.
3362 Installed Greg McGary's integration of the hash functions from the
3363 GNU id-utils package:
3365 2002-07-10 Greg McGary <greg@mcgary.org>
3367 * scripts/functions/filter-out: Add literals to to the
3368 pattern space in order to add complexity, and trigger
3369 use of an internal hash table. Fix documentation strings.
3370 * scripts/targets/INTERMEDIATE: Reverse order of files
3371 passed to expected `rm' command.
3373 2002-07-10 Greg McGary <greg@mcgary.org>

3465 2002-07-10 Paul D. Smith <psmith@gnu.org>
3467 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3468 prerequisite list. A real SysV make will expand the entire
3469 prerequisites list _twice_: we don't do that as it's a big
3470 backward-compatibility problem. We only replace those specific
3473 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3474 references left in the list of prerequisites. Check for .POSIX as
3475 we record targets, so we can disable non-POSIX behavior while
3476 reading makefiles as well as running them.
3477 (eval): Check the prerequisite list to see if we have anything
3478 that looks like a SysV prerequisite variable reference.
3480 2002-07-09 Paul D. Smith <psmith@gnu.org>
3482 * doc/make.texi (Prerequisite Types): Add a new section describing
3483 order-only prerequisites.
3485 * read.c (uniquize_deps): If we have the same file as both a
3486 normal and order-only prereq, get rid of the order-only prereq,
3487 since the normal one supersedes it.
3489 2002-07-08 Paul D. Smith <psmith@gnu.org>
3491 * AUTHORS: Added Greg McGary to the AUTHORS file.
3492 * NEWS: Blurbed order-only prerequisites.
3493 * file.c (print_file): Show order-only deps properly when printing
3496 * maintMakefile: Add "update" targets for wget'ing the latest
3497 versions of various external files. Taken from Makefile.maint in
3500 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3501 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3503 2002-07-07 Paul D. Smith <psmith@gnu.org>
3505 * po/*.po: Remove. We'll use wget to retrieve them at release
3508 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3509 rather than a shell you get an exception. Make sure we look up
3510 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3512 * remake.c (notice_finished_file): Fix handling of -t flag.
3513 Patch provided by Henning Makholm <henning@makholm.net>.
3515 * implicit.c (pattern_search): Some systems apparently run short
3516 of stack space, and using alloca() in this function caused an
3517 overrun. I modified it to use xmalloc() on the two variables
3518 which seemed like they might get large. Fixes Bug #476.
3520 * main.c (print_version): Update copyright notice to conform with
3522 (print_usage): Update help output.
3524 * function.c (func_eval): Create a new make function, $(eval
3525 ...). Expand the arguments, put them into a buffer, then invoke
3526 eval_buffer() on the resulting string.
3527 (func_quote): Create a new function, $(quote VARNAME). Inserts
3528 the value of the variable VARNAME without expanding it any
3531 * read.c (struct ebuffer): Change the linebuffer structure to an
3532 "eval buffer", which can be either a file or a buffer.
3533 (eval_makefile): Move the code in the old read_makefile() which
3534 located a makefile into here: create a struct ebuffer with that
3535 information. Have it invoke the new function eval() with that
3537 (eval_buffer): Create a new function that creates a struct ebuffer
3538 that holds a string buffer instead of a file. Have it invoke
3539 eval() with that ebuffer.
3540 (eval): New function that contains the guts of the old
3541 read_makefile() function: this function parses makefiles. Obtains
3542 data to parse from the provided ebuffer. Some modifications to
3543 make the flow of the function cleaner and clearer. Still could
3544 use some work here...
3545 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3546 contents of the define/endef variable from the ebuffer.
3547 (readstring): Read the next line from a string-style ebuffer.
3548 (readline): Read the next line from an ebuffer. If it's a string
3549 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3552 * dep.h (eval_buffer): Prototype eval_buffer();
3554 * variable.c (do_variable_definition): Make sure that all
3555 non-target-specific variables are registered in the global set.
3556 If we're invoked from an $(eval ...) we might be inside a $(call
3557 ...) or other function which has pushed a variable scope; we still
3558 want to define our variables from evaluated makefile code in the
3561 2002-07-03 Greg McGary <greg@mcgary.org>
3563 * dep.h (struct dep) [ignore_mtime]: New member.
3564 [changed]: convert to a bitfield.
3565 * implicit.c (pattern_search): Zero ignore_mtime.
3566 * main.c (main, handle_non_switch_argument): Likewise.
3567 * rule.c (convert_suffix_rule): Likewise.
3568 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3569 (read_makefile): Parse '|' in prerequisite list.
3570 (uniquize_deps): Consider ignore_mtime when comparing deps.
3571 * remake.c (update_file_1, check_dep): Don't force remake for
3572 dependencies that have d->ignore_mtime.
3573 * commands.c (FILE_LIST_SEPARATOR): New constant.
3574 (set_file_variables): Don't include a
3575 prerequisite in $+, $^ or $? if d->ignore_mtime.
3578 2002-06-18 Paul D. Smith <psmith@gnu.org>
3580 * make.texinfo: Updates for next revision. New date/rev/etc.
3581 Recreate all Info menus. Change license on the manual to the GNU
3582 Free Documentation License. A number of typos.
3583 (Variables Simplify): Don't use "-" before it's defined.
3584 (Automatic Prerequisites): Rewrite the target example to work
3585 properly if the compile fails. Remove incorrect comments about
3586 how "set -e" behaves.
3587 (Text Functions): Move the "word", "wordlist", "words", and
3588 "firstword" functions here, from "File Name Functions".
3589 * make-stds.texi: Update from latest GNU version.
3590 * fdl.texi: (created) Import the latest GNU version.
3592 2002-06-06 Paul D. Smith <psmith@gnu.org>
3594 * variable.c (do_variable_definition): New function: extract the
3595 part of try_variable_definition() that actually sets the value
3596 into a separate function.
3597 (try_variable_definition): Call do_variable_definition() after
3598 parsing the variable definition string.
3599 (define_variable_in_set): Make the name argument const.
3601 * variable.h (enum variable_flavor): Make public.
3602 (do_variable_definition): Create prototype.
3604 * read.c (read_all_makefiles): Create a new built-in variable,
3606 (read_makefile): Add each makefile read in to this variable value.
3608 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3610 * Makefile.DOS.template: Tweak according to changes in the
3611 distribution. Add back the dependencies of *.o files.
3613 * configh.dos.template: Synchronize with config.h.in.
3615 2002-05-09 Paul D. Smith <psmith@gnu.org>
3617 * file.c (file_timestamp_now): Use K&R function declaration.
3619 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3620 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3621 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3622 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3623 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3624 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3625 nlist.n_name is a pointer rather than an array.
3627 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3628 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3629 * configure.in: Use it instead of the old version.
3631 * main.c (main): Prefer setvbuf() to setlinebuf().
3633 2002-05-08 Paul D. Smith <psmith@gnu.org>
3635 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3636 (loadavg_LDADD): Ditto.
3638 2002-04-29 Paul D. Smith <psmith@gnu.org>
3640 * expand.c (recursively_expand_for_file): Rename
3641 recursively_expand() to recursively_expand_for_file() and provide
3642 an extra argument, struct file. If the argument is provided, set
3643 the variable scope to that of the file before expanding.
3644 * variable.h (recursively_expand): Make this a macro that invokes
3645 recursively_expand_for_file() with a NULL file pointer.
3646 * variable.c (target_environment): Call the renamed function and
3647 provide the current file context.
3648 Fixes Debian bug #144306.
3650 2002-04-28 Paul D. Smith <psmith@gnu.org>
3652 Allow $(call ...) user-defined variables to be self-referencing
3653 without throwing an error. Allows implementation of transitive
3654 closures, among other possibly useful things.
3655 Requested by: Philip Guenther <guenther@sendmail.com>
3657 * variable.h (struct variable): Add a new field: exp_count, and
3658 new macros to hold its size and maximum value.
3659 (warn_undefined): Make this a macro.
3660 * variable.c (define_variable_in_set): Initialize it.
3661 * expand.c (recursively_expand): If we detect recursive expansion
3662 of a variable, check the exp_count field. If it's greater than 0
3663 allow the recursion and decrement the count.
3664 (warn_undefined): Remove this (now a macro in variable.h).
3665 * function.c (func_call): Before we expand the user-defined
3666 function, modify its exp_count field to contain the maximum
3667 number of recursive calls we'll allow. After the call, reset it
3670 2002-04-21 Paul D. Smith <psmith@gnu.org>
3672 Modified to use latest autoconf (2.53), automake (1.6.1), and
3673 gettext (0.11.1). We're using gettext's new "external" support,
3674 to avoid including libintl source with GNU make.
3676 * README.cvs: New file. Explain how to build GNU make from CVS.
3678 * configure.in: Modify checking for the system glob library.
3679 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3680 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3681 etc. will manage it correctly). Set an automake conditional
3682 USE_LOCAL_GLOB to decide whether to compile the glob library.
3684 * getloadavg.c (main): Include make.h in the "TEST" program to
3687 * Makefile.am: Remove special rules for loadavg. Replace them
3688 with Automake capabilities for building extra programs.
3690 * signame.c: This file does nothing if the system provide
3691 strsignal(). If not, it implements strsignal(). If the system
3692 doesn't define sys_siglist, then we make our own; otherwise we use
3694 * signame.h: Removed.
3696 * main.c (main): No need to invoke signame_init(). Update copyright.
3698 * ABOUT-NLS: Removed.
3699 * gettext.c: Removed.
3700 * gettext.h: Get a simplified copy from the gettext package.
3702 * i18n/*.po: Moved to po/.
3705 * config/*: Created. Contains package configuration helper files.
3706 * config.guess, config.sub: Moved to config directory.
3708 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3709 Rework to use new-style autoconf features. Use the "external"
3710 mode for gettext. Make the build.sh config file conditional on
3711 whether build.sh.in exists, to avoid autoconf errors.
3712 * acinclude.m4: Removed almost all macros as being obsolete.
3713 Rewrote remaining macros to use AC_DEFINE.
3714 * acconfig.h: Removed.
3716 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3717 conditional to handle customs support. Remove special handling
3720 2002-04-20 Paul D. Smith <psmith@gnu.org>
3722 * function.c (func_call): Don't mark the argument variables $1,
3723 etc. as recursive. They've already been fully expanded so
3724 there's no need to do it again, and doing so strips escaped $'s.
3725 Reported by Sebastian Glita <glseba@yahoo.com>.
3727 * remake.c (notice_finished_file): Walk through double-colon
3728 entries via the prev field, not the next field!
3729 Reported by Greg McGary <greg@mcgary.org>.
3731 * main.c (main): If the user specifies -q and asks for a specific
3732 target which is a makefile, we got an assert. In that case it
3733 turns out we should continue normally instead.
3735 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3737 * i18n/he.po: Installed a new translation.
3739 2002-01-07 Paul D. Smith <psmith@gnu.org>
3741 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3743 2001-12-04 Paul D. Smith <psmith@gnu.org>
3745 * i18n/ja.po: Installed an updated translation.
3747 2001-09-06 Paul Eggert <eggert@twinsun.com>
3749 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3750 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3752 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3754 (main): Get rid of any avoidable limit on stack size.
3756 2001-09-04 Paul D. Smith <psmith@gnu.org>
3758 * i18n/da.po: Installed an updated translation.
3760 2001-08-03 Paul D. Smith <psmith@gnu.org>
3762 * i18n/fr.po: Installed an updated translation.
3763 Resolves Debian bug #106720.
3765 2001-06-13 Paul D. Smith <psmith@gnu.org>
3767 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3770 2001-06-11 Paul D. Smith <psmith@gnu.org>
3772 * i18n/ko.po: Installed a new translation.
3774 2001-05-06 Paul D. Smith <psmith@gnu.org>
3776 Modify the EINTR handling.
3778 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3779 the way in which we manage the file descriptor/signal handler race
3780 trap to be more efficient.
3782 2001-05-06 Paul Eggert <eggert@twinsun.com>
3784 Restart almost all system calls that are interrupted, instead
3785 of worrying about EINTR. The lone exception is the read() for
3788 * configure.in (HAVE_SA_RESTART): New macro.
3789 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3790 * main.c (main): Use SA_RESTART instead of the old,
3791 nonstandard SA_INTERRUPT.
3793 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3794 * main.c (bsd_signal): New function or macro,
3795 if the implementation doesn't supply it.
3796 (The bsd_signal function will be in POSIX 1003.1-200x.)
3797 (HANDLESIG): Remove.
3798 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3800 * make.h (EINTR_SET): Remove.
3801 (SA_RESTART): New macro.
3803 * arscan.c (ar_member_touch): Don't worry about EINTR.
3804 * function.c (func_shell): Likewise.
3805 * job.c (reap_children, free_child, new_job): Likewise.
3806 * main.c (main): Likewise.
3807 * remake.c (touch_file, name_mtime): Likewise.
3809 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3810 if fstat failed with errno!=EINTR, the error was ignored.
3812 * job.c (set_child_handler_action_flags): New function.
3813 (new_job): Use it to temporarily clear the SIGCHLD action flags
3814 while reading the token.
3816 2001-05-02 Paul D. Smith <psmith@gnu.org>
3818 * job.c (start_job_command): Don't add define/endef per-line flags
3819 to the top-level flags setting.
3821 2001-04-03 Paul D. Smith <psmith@gnu.org>
3823 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3824 bit on error, so check for odd return values, not non-0 return
3826 (VMS_get_member_info): Calculate the timezone differences correctly.
3827 Reported by John Fowler <jfowler@nyx.net>.
3830 2001-03-14 Paul D. Smith <psmith@gnu.org>
3832 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3833 value before invoking define_variable().
3834 Reported by John Fowler <jfowler@nyx.net>.
3836 2001-02-07 Paul D. Smith <psmith@gnu.org>
3838 * read.c (record_target_var): If we reset the variable due to a
3839 command-line variable setting overriding it, turn off the "append"
3842 2001-01-17 Paul D. Smith <psmith@gnu.org>
3844 * variable.c (lookup_variable) [VMS]: When getting values from the
3845 environment, allocate enough space for the _value_ plus escapes,
3846 not enough space for the name plus escapes :-/.
3847 Reported by John Fowler <jfowler@nyx.net>.
3849 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3850 warnings that make generates, so it doesn't look like an error.
3851 Reported by Karl Berry <karl@gnu.org>.
3854 Fix for PR/2020: Rework appended target-specific variables. I'm
3855 fairly confident this algorithm is finally correct.
3857 * expand.c (allocated_variable_append): Rewrite. Instead of
3858 expanding each appended variable then adding all the expanded
3859 strings together, we append all the unexpanded values going up
3860 through the variable set contexts, then expand the final result.
3861 This behaves just like non-target-specific appended variable
3862 values, while the old way didn't in various corner cases.
3863 (variable_append): New function: recursively append the unexpanded
3864 value of a variable, walking from the outermost variable scope to
3866 * variable.c (lookup_variable): Remove the code that looked up the
3867 variable set list if the found variable was "append". We don't
3869 (lookup_variable_in_set): Make this non-static so we can use it
3871 (try_variable_definition): Use lookup_variable_in_set() rather
3872 than faking out current_variable_set_list by hand (cleanup).
3873 * variable.h: Add a prototype for the now non-static
3874 lookup_variable_in_set().
3876 2000-11-17 Paul D. Smith <psmith@gnu.org>
3878 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3879 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3880 before throwing a fit.
3882 2000-11-17 Paul D. Smith <psmith@gnu.org>
3884 * read.c (readline): CRLF calculations had a hole, if you hit the
3885 buffer grow scenario just right. Reworked the algorithm to avoid
3886 the need for len or lastlen at all. Problem description with
3887 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3889 2000-10-24 Paul D. Smith <psmith@gnu.org>
3891 * gettext.c (SWAP): Declare this with the prototype, otherwise
3892 some systems don't work (non-32-bit? Reported for Cray T3E).
3893 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3895 2000-10-05 Paul D. Smith <psmith@gnu.org>
3897 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3898 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3900 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3902 2000-09-22 Paul D. Smith <psmith@gnu.org>
3904 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3905 parts of the real gettext.h here, and we expect to really include
3906 the real gettext.h later. If we keep this #define, it's ignored.
3908 2000-09-21 Paul D. Smith <psmith@gnu.org>
3910 * main.c (log_working_directory): Rework the text to use complete
3911 sentences, to make life simpler for the translators.
3913 2000-08-29 Paul D. Smith <psmith@gnu.org>
3915 * file.c (remove_intermediates): Print a debug message before we
3916 remove intermediate files, so the user (if she uses -d) knows
3919 2000-08-21 Paul D. Smith <psmith@gnu.org>
3921 * variable.c (try_variable_definition): Change how we handle
3922 target-specific append variable defns: instead of just setting the
3923 value, expand it as an append _but_ only within the current
3924 target's context. Otherwise we lose all but the last value if the
3925 variable is appended more than once within the current target
3926 context. Fixes PR/1831.
3928 2000-08-16 Paul D. Smith <psmith@gnu.org>
3930 * function.c (func_shell): Nul-terminate the buffer before
3931 printing an exec error message (just in case it's not!).
3932 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3934 2000-07-25 Paul D. Smith <psmith@gnu.org>
3936 * job.c (construct_command_argv_internal): Add "~" to the list of
3937 sh_chars[] which disallow optimizing out the shell call.
3939 2000-07-23 Paul Eggert <eggert@twinsun.com>
3941 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3942 supersedes --disable-nsec-timestamps.
3943 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3944 * README: Remove --disable-nsec-timestamps.
3946 * filedef.h (struct file.low_resolution_time): New member.
3947 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3948 * remake.c (update_file_1):
3949 Avoid spurious rebuilds due to low resolution time stamps,
3950 generalizing the earlier code that applied only to archive members.
3951 (f_mtime): Archive members always have low resolution time stamps.
3953 * configure.in: Remove --disable-nsec-timestamps, as this has
3954 been superseded by .LOW_RESOLUTION_TIME.
3956 2000-07-23 Paul Eggert <eggert@twinsun.com>
3958 * configure.in (enable_nsec_timestamps): Renamed from
3959 make_cv_nsec_timestamps, since enable/disable options
3960 shouldn't be cached.
3962 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3963 and Paul Eggert <eggert@twinsun.com>
3965 * file.c (file_timestamp_now):
3966 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3967 so that clock_gettime is not linked unless needed.
3969 * filedef.h (FILE_TIMESTAMP_HI_RES):
3970 Remove definition; "configure" now does this.
3972 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3973 to before high resolution file timestamp check,
3974 since that check now uses uintmax_t.
3975 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3976 high resolution file timestamps.
3977 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3978 so that we don't link in clock_gettime unnecessarily.
3980 2000-07-17 Paul D. Smith <psmith@gnu.org>
3982 * i18n/ja.po: New version of the translation file.
3984 2000-07-07 Paul D. Smith <psmith@gnu.org>
3986 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3987 the offset calculation.
3988 (name_mtime): Replace EINTR test with EINTR_SET macro.
3990 2000-07-07 Paul Eggert <eggert@twinsun.com>
3994 * remake.c (update_file_1):
3995 Avoid spurious rebuilds of archive members due to their
3996 timestamp resolution being only one second.
3997 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3998 the clock's resolution being lower than file timestamps'.
3999 When warning about future timestamps, report only the discrepancy,
4000 not the absolute value of the timestamp and the current time.
4002 * file.c (file_timestamp_now): New arg RESOLUTION.
4003 * filedef.h (file_timestamp_now): Likewise.
4004 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4006 2000-07-05 Paul D. Smith <psmith@gnu.org>
4008 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4009 to listp. Fixes PR/1793.
4011 2000-06-26 Paul Eggert <eggert@twinsun.com>
4013 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4015 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4017 * remake.c (f_mtime): Remove unused var memtime.
4019 2000-06-25 Martin Buchholz <martin@xemacs.org>
4021 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4022 Ran spell-check on make.texinfo.
4024 2000-06-23 Paul D. Smith <psmith@gnu.org>
4026 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4027 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4028 * make.h: Define these macros.
4030 * Version 3.79.1 released.
4032 * configure.in: Add a new option, --disable-nsec-timestamps, to
4033 avoid using sub-second timestamps on systems that support it. It
4034 can lead to problems, e.g. if your makefile relies on "cp -p".
4035 * README.template: Document the issue with "cp -p".
4037 * config.guess, config.sub: Updated.
