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

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

332 2009-10-03 Paul Smith <psmith@gnu.org>
334 * make.h: Include <alloca.h> even on systems where __GNUC__ is

394 double-colons have a different meaning. Savannah bug #27497.
396 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
398 * configh.dos.template: Remove unconditional definition of
399 SYS_SIGLIST_DECLARED.
400 Include <sys/version.h> because ports of GCC 4.3.0 and later no
401 longer include it, so macros like __DJGPP_MINOR__ are no longer
402 defined automatically.
404 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
405 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
406 instead of using the hardcoded ones.
407 (SUBDIRS): doc subdir added.
408 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
409 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
410 create html formated docs. texi2html may not be ported to DOS.
411 (make.info, make.dvi, make.ps, make.html): Make targets depend on
413 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
414 -I switch to look in ./ instead of ./doc.

416 (make_1.html): Removed.
417 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

420 (mostlyclean-recursive, clean-recursive, distclean-recursive)
421 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
422 (tags-recursive): Allow for more than one subdir in the build
424 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
425 targets. Enter into doc/ to produce the targets.
426 (all-am): $(INFO_DEPS) replaced by info.
428 2009-09-26 Paul Smith <psmith@gnu.org>
430 * read.c (record_files): Use free_ns() to free struct nameseq.
433 * rule.c (freerule): Use free_dep_chain().
435 * read.c (record_files): Free FILENAMES chain for implicit rules.
436 (eval): Static pattern targets go into the string cache.
438 * function.c (string_glob): Free NAME in the nameseq chain.
440 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
442 * implicit.c (pattern_search): Terminate early if we haven't
443 found any rules to try (performance improvement).
445 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
447 * implicit.c (pattern_search): Merge three parallel arrays,
448 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
449 of struct TRYRULE. In the old version the latter two arrays
450 had insufficient length.
452 2009-09-24 Paul Smith <psmith@gnu.org>
454 * implicit.c (pattern_search): Add back support for order-only
455 prerequisites for secondary expansion implicit rules, that were
456 accidentally dropped. If we find a "|", enable order-only mode
457 and set IGNORE_MTIME on all deps that are seen afterward.
458 (pattern_search): Fix memory leaks: for intermediate files where
459 we've already set the file variable and pattern variable sets, be
460 sure to either save or free them as appropriate.
462 2009-09-23 Paul Smith <psmith@gnu.org>
464 Rework the way secondary expansion is stored, for efficiency.
465 This changes secondary expansion so that ONLY WHEN we know we have
466 a possibility of needing secondary expansion, do we defer the
467 secondary expansion. This means more parsing the deps but we use
468 a lot less memory (due to the strcache). Also, this fixes
471 * read.c (eval): Don't parse the dep string here anymore.
472 (record_files): Take the dep argument as an unparsed string. If
473 secondary expansion is enabled AND the prereq string has a '$' in
474 it, then set NEED_2ND_EXPANSION and keep the entire string.
475 Otherwise, parse the dep string here to construct the dep list
476 with the names in the strcache.
478 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
479 duplicate the name string (others are in the strcache).
481 * implicit.c: Remove struct idep and free_idep_chain(): unused.
482 (struct patdeps): New structure to store prereq information.
483 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
484 which prerequisites need expansion, and expand only those.
486 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
487 and enter_prereqs(). split_prereqs() takes a fully-expanded string
488 and splits it into a DEP list, handling order-only prereqs.
489 (enter_prereqs): This function enters a list of DEPs into the file
490 database. If there's a stem defined, expand any pattern chars.
491 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
492 set. Use the above functions.
493 (snap_deps): Only perform second expansion on prereqs that need it,
494 as defined by the NEED_2ND_EXPANSION flag.
495 (print_prereqs): New function to print the prereqs
496 (print_file): Call print_prereqs() rather than print inline.
498 * hash.h (STRING_COMPARE): Take advantage of strcache() by
500 (STRING_N_COMPARE): Ditto.
501 (ISTRING_COMPARE): Ditto.
503 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
504 (parse_file_seq): Return void*
505 * read.c (parse_file_seq): Return void*.
506 (eval): Invoke macroized version of parse_file_seq()
507 * default.c (set_default_suffixes): Ditto.
508 * file.c (split_prereqs): Ditto.
509 * function.c (string_glob): Ditto.
510 * main.c (main): Ditto.
511 * rule.c (install_pattern_rule): Ditto.
513 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
515 2009-09-16 Paul Smith <psmith@gnu.org>
517 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
519 * dep.h: Create alloc_dep() / free_dep() macros.
521 * implicit.c (pattern_search): Take advantage of the new
522 parse_file_seq() to add the directory prefix to each prereq.
524 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
525 all. Avoid reversing chains. Support adding prefixes.
526 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
527 cached/non-cached results.
528 (eval): Remove multi_glob() & invoke new parse_file_seq().
529 * rule.c (install_pattern_rule): Ditto.
530 * main.c (main): Ditto.
531 * implicit.c (pattern_search): Ditto.
532 * function.c (string_glob): Ditto.
533 * file.c (parse_prereqs): Ditto.
534 * default.c (set_default_suffixes): Ditto.
536 * variable.c (parse_variable_definition): Don't run off the end of
537 the string if it ends in whitespace (found with valgrind).
539 * commands.c (set_file_variables): Keep space for all targets in
540 $? if -B is given (found with valgrind).
542 2009-09-15 Paul Smith <psmith@gnu.org>
544 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
545 (xcalloc): Add new function.
546 * make.h: New declarations.
548 * ar.c (ar_glob_match): New calling method for concat().
549 * main.c (main): Ditto.

554 * variable.c (target_environment): Ditto.
555 (sync_Path_environment): Ditto.
557 * ar.c (ar_glob_match): Use xcalloc().
558 * dir.c (file_impossible): Ditto.
559 * file.c (enter_file): Ditto.
560 * job.c (new_job): Ditto.
561 * read.c (parse_file_seq): Ditto.
562 * vmsfunctions.c (opendir): Ditto.
564 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
566 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
567 inside the loop that looks up environment for PATH.
569 2009-08-31 Eli Zaretskii <eliz@gnu.org>
571 * function.c (windows32_openpipe): Update envp after calling
572 sync_Path_environment.
574 2009-08-02 Paul Smith <psmith@gnu.org>
576 * remake.c (notice_finished_file): Ensure file->cmds is not null
577 before looping through them. Fixes Savannah bug #21824.
579 * doc/make.texi (Wildcard Examples): Clarify when objects is
580 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
581 (Include): Clarify the behavior of -include.
582 Fixes Savannah bug #18963.
584 2009-08-01 Paul Smith <psmith@gnu.org>
586 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
587 etc. come on the command line. Fixes Savannah bug #27093.
589 * expand.c (expand_argument): If the argument is large enough use
590 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
592 * variable.c (do_variable_definition): Avoid using alloca() to
593 hold values, which can be large. Fixes Savannah bug #23960.
595 * job.c (new_job): Use memmove() instead of strcpy() since both
596 pointers are in the same memory block. Fixes Savannah bug #27148.
597 Patch by Petr Machata.
599 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
601 * job.c (construct_command_argv_internal): Add "ulimit" and
602 "unset" to the sh_cmds for Unixy shells.
604 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
606 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
607 that set make_cv_sys_gnu_glob, so they are also correctly set
608 when the cache has been populated before.
610 2009-07-04 Eli Zaretskii <eliz@gnu.org>
612 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
613 exist, as realpath(3) does where it's supported.
615 2006-07-04 Eli Zaretskii <eliz@gnu.org>
617 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
618 (abspath): Support systems that define HAVE_DOS_PATHS (have
619 drive letters in their file names). Use IS_PATHSEP instead of a
620 literal '/' comparison. Fixes Savannah bug #26886.
622 2009-06-14 Paul Smith <psmith@gnu.org>
624 * remake.c (update_file_1): Remember the original file we marked
625 as updating, so we can clear that flag again. If we find a target
626 via vpath, FILE might change.
627 (check_dep): Ditto. Fixes Savannah bug #13529.
628 Patch by Reid Madsen <reid.madsen@tek.com>.
630 2009-06-13 Paul Smith <psmith@gnu.org>
632 * doc/make.texi (MAKEFILES Variable): Be explicit that files
633 included by MAKEFILES cannot give default goals.
634 * read.c (eval): If set_default is not set, pass the no-default-goal
635 value when we read included makefiles. Fixes Savannah bug #13401.
637 * ar.c (ar_name): Ensure that targets with empty parens aren't
638 considered archive member references: archive members must have a
639 non-empty "member" string. Fixes Savannah bug #18435.
641 * function.c (string_glob): Rely on multi_glob() to determine
642 whether files exist or not. Remove call to file_exists_p() which
643 is not always correct. Fixes Savannah bug #21231.
644 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
645 then only files that really exist will be returned.
646 * dep.h: Add new argument to multi_glob().
647 * rule.c (install_pattern_rule): Ditto.
648 * read.c (eval): Ditto.
649 * main.c (main): Ditto.
650 * implicit.c (pattern_search): Ditto.
651 * file.c (parse_prereqs): Ditto.
652 * default.c (set_default_suffixes): Ditto.
654 2009-06-09 Paul Smith <psmith@gnu.org>
656 * commands.c (set_file_variables): If always_make_flag is set,
657 always add the prereq to $?. Fixes Savannah bug #17825.
659 * remake.c (update_file_1): When rebuilding deps of FILE, also try
660 to rebuild the deps of all the also_make targets for that file.
661 Fixes Savannah bug #19108.
663 * implicit.c (pattern_search): Undo test for is_target, added by
664 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
665 Rule Search Algorithm". Fixes Savannah bug #17752.
667 * main.c (clean_jobserver): Clear the jobserver_fds options and
668 set job_slots to the default when we clean up.
669 (define_makeflags): Return the new MAKEFLAGS value.
670 (main): Reset MAKEFLAGS in the environment when we re-exec.
671 Fixes Savannah bug #18124.
673 2009-06-08 Paul Smith <psmith@gnu.org>
675 * read.c (eval): Collapse continuations post-semicolon on target-
676 specific variables. Fixes Savannah bug #17521.
678 2009-06-07 Paul Smith <psmith@gnu.org>
680 * job.c (reap_children): For older systems without waitpid() (are
681 there any of these left?) run wait(2) inside EINTRLOOP to handle
682 EINTR errors. Fixes Savannah bug #16401.
684 * (various): Debug message cleanup. Fixes Savannah bug #16469.
686 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
688 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
689 not the end, to catch second expansion $(eval ...) defining new
690 target/prereq relationships during snap_deps.
691 Fixes Savannah bug #24622.
693 * read.c (record_files): The second-expansion "f->updating" hack
694 was not completely correct: if assumed that the target with
695 commands always had prerequisites; if one didn't then the ordering
696 was messed up. Fixed for now to use f->updating to decide whether
697 to preserve the last element in the deps list... but this whole
698 area of constructing and reversing the deps list is too confusing
699 and needs to be reworked. Fixes Savannah bug #21198.
701 2009-06-06 Paul Smith <psmith@gnu.org>
703 * hash.c (hash_insert): Remove useless test for NULL.
704 Fixes Savannah bug #21823.
706 * make.h: Move SET_STACK_SIZE determination to make.h.
707 * main.c (main): New global variable, STACK_LIMIT, holds the
708 original stack limit when make was started.
709 * job.c (start_job_command): Reset the stack limit, if we changed it.
710 Fixes Savannah bug #22010.
712 * remake.c (check_dep): Only set the target's state to not-started
713 if it's not already running. Found this while testing -j10 builds
714 of glibc: various targets were being rebuilt multiple times.
715 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
718 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
719 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
722 2009-06-04 Paul Smith <psmith@gnu.org>
724 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
726 * maintMakefile: Modify access of config and gnulib Savannah
727 modules to use GIT instead of CVS.
729 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
730 Fixes Savannah bug #24655.
732 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
733 this can happen during some invocations of $(eval ...) for example.
734 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
736 2009-06-02 Paul Smith <psmith@gnu.org>
738 * configure.in: Check for fileno()
739 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
740 for the makefile file so invocations of $(shell ...) don't inherit it.
741 Fixes Savannah bug #24277.
743 2009-06-01 Paul Smith <psmith@gnu.org>
745 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
746 expansion was handled incorrectly. Rework the default goal
747 handling to save the variable only. Remove default_goal_file and
749 * read.c (eval): Check default_goal_var, not default_goal_name.
750 * read.c (record_target_var): Don't check default_goal_file here.
752 2009-05-31 Paul Smith <psmith@gnu.org>
754 * main.c (main): Expand the .DEFAULT_GOAL variable before using
755 it, and if the multi_glob() returns nothing (say it expanded to
756 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
758 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
759 $(and ..) to the reference. Fixes Savannah bug #25694.
761 * make.1: Be clear that some recipes will be executed even with -n.
762 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
764 * doc/make.texi (Override Directive): Make more clear how
765 overrides and appends interact.
766 Elucidates part of Savannah bug #26207.
768 * read.c (record_target_var): Don't reset the origin on
769 target-specific variables; try_variable_definition() will handle
770 this correctly. Fixes Savannah bug #26207.
772 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
773 Fixes Savannah bug #25712.
775 * implicit.c (pattern_search): Keep a pointer to the beginning of
776 the filename and save that instead of the constructed pointer.
777 Fixes Savannah bug #26593.
778 Patch by Mark Seaborn <mrs@mythic-beasts.com>
780 2009-05-30 Paul Smith <psmith@gnu.org>
782 * doc/make.texi (Multi-Line): Add a description of the new abilities
783 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
784 "command sequence" vs. "recipe" syntax.
785 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
786 after a define, to create variables with those flavors.
788 2009-05-25 Paul Smith <psmith@gnu.org>
790 Reworked the parser for variable assignments to allow multiple
791 modifiers, and in any order. Also allows variable and
792 prerequisites to be modifier names ('export', 'private', etc.)
794 * NEWS: Add notes about user-visible changes.
796 * read.c (struct vmodifiers): Remember what modifiers were seen.
797 (parse_var_assignment): New function to parse variable assignments.
798 (eval): Call the new function. Handle variable assignments earlier.
800 * variable.c (parse_variable_definition): Only parse; don't create var.
801 (assign_variable_definition): Call parse, then create the var.
803 2009-05-24 Paul Smith <psmith@gnu.org>
805 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
806 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
808 2009-03-14 Eli Zaretskii <eliz@gnu.org>
810 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
811 Fixes Savannah bug #25412.
813 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
814 prototype for xmalloc.
815 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
816 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
817 Loop over an array of extensions, instead of duplicating the same
818 code inline. Use SearchPath followed by CreateFile, instead of
819 the obsolete OpenFile. Fixes Savannah bug #17277.
820 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
821 to `find_file'. Fixes Savannah bug #25662.
823 2009-03-07 Eli Zaretskii <eliz@gnu.org>
825 * function.c (func_shell): Don't close pipedes[1] if it is -1.
826 Fixes Savannah bug #20495.
828 2009-02-28 Ralf Wildenhues <address@hidden>
830 * doc/make.texi (Instead of Execution): Document interaction of
831 -t with phony targets.
833 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
835 Introduce a new keyword "private" which applies to target-specific
836 variables and prevents their values from being inherited.
838 * variable.h (struct variable): Add private_var flag to each variable.
839 Add a flag to specify which list entry switches to the parent target.

859 2008-09-30 Eli Zaretskii <eliz@gnu.org>
861 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
864 * w32/subproc/build.bat (GCCBuild): Likewise.

868 * job.c (construct_command_argv_internal): Avoid extra backslash
869 in batch-mode Unixy shells. Under DB_JOBS, display the contents
872 2008-05-31 Eli Zaretskii <eliz@gnu.org>
874 * README.W32.template: Remove obsolete text about non-support for
875 -jN without Unixy shell. Remove obsolete text about not supplying
876 Visual Studio project files (we do supply them). Modify text to
877 prefer GCC builds to MSC builds.
879 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
881 * doc/make.texi (Empty Targets): Fix typo.
883 2008-03-27 Paul Smith <psmith@gnu.org>

896 `value' field is NULL.
898 2007-12-22 Eli Zaretskii <eliz@gnu.org>
900 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
902 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
903 (TEXINFOS): Value changed to `doc/make.texi'.
904 (.SUFFIXES): Use .texi instead of .texinfo.
905 (make.info, make.dvi): Depend on doc/make.texi.
906 (.texi.info): New target, instead of ".texinfo.info". Change -I
907 switch to $(MAKEINFO) to look in doc/. Use --no-split.
908 (.texi): New target, instead of ".texinfo". Change -I switch to
909 $(MAKEINFO) to look in doc/. Use --no-split.
910 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
911 switch to $(MAKEINFO) to look in doc/.
912 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

915 (html, make_1.html): New targets.
916 (.PHONY): Add "html".
917 (.SUFFIXES): Add .html.
919 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
921 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
922 HAVE_DECL_SYS_SIGLIST.
924 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
925 build does not use child_execute_job.
927 * variable.c (define_automatic_variables) [__MSDOS__]: Always
928 export the SHELL environment variable to the child.
930 2007-12-22 Eli Zaretskii <eliz@gnu.org>
932 * config.h.W32: Include sys/types.h.
933 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

949 * remake.c (f_mtime): Print time difference values between 100 and
950 ULONG_MAX in fixed-point notation rather than in exponention notation.
952 2007-10-12 Eli Zaretskii <eliz@gnu.org>
954 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
955 a more complex value than a simple shell: if it's not a default
956 shell now then expand it and see if is a default shell then.
958 2007-10-10 Eli Zaretskii <eliz@gnu.org>
960 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
961 pathnames, with const strings.
962 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
963 from the template (used for building from CVS, not a dist).
965 2007-10-10 Paul Smith <psmith@gnu.org>
967 * make.h: Add a prototype for w32_kill() (change suggested by
968 Yongwei Wu <wuyongwei@gmail.com>).
970 2007-09-21 Eli Zaretskii <eliz@gnu.org>
972 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
975 2007-09-12 Paul Smith <psmith@gnu.org>
977 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
978 Provided by Diego Biurrun <diego@biurrun.de>
979 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
980 Provided by Diego Biurrun <diego@biurrun.de>
982 2007-09-11 Paul Smith <psmith@gnu.org>
984 * doc/make.texi (Special Variables): Moved this into the "How to
985 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

987 "Special Variables" section.
988 (Rule Introduction): Reference .RECIPEPREFIX.
989 (Simple Makefile): Ditto.
990 (Rule Syntax): Ditto.
991 (Command Syntax): Ditto.
992 (Error Messages): Ditto.
994 2007-09-10 Paul Smith <psmith@gnu.org>
996 * commands.c (print_commands): Don't print an extra line in the
997 command scripts. Prefix the command scripts with cmd_prefix, not \t.
999 * read.c (construct_include_path): Add the full string to the cache; we
1000 were chopping the last char.
1002 * NEWS: Announce the .RECIPEPREFIX special variable.
1003 * variable.c (lookup_special_var): Rename from handle_special_var().
1004 (lookup_variable): Call the new name.
1005 (set_special_var): New function: handle setting of special variables.
1006 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1007 (do_variable_definition): Call it.

1009 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1010 * main.c (main): Create the .RECIPEPREFIX special variable.
1011 * read.c (eval): Remove the cmd_prefix characters from the command
1012 scripts here, so they're not stored in the commands array at all,
1013 rather than waiting and stripping them out during command construction.
1014 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1016 2007-08-15 Paul Smith <psmith@gnu.org>
1018 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1019 file has had the section info removed, so add some to make.texi
1020 before we include it.
1022 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1024 * remake.c (check_dep): Reset the target state for intermediate
1025 files. They might have been considered before but not updated
1026 then (order-only for example) but they will be this time.
1027 Fixes Savannah bug #'s 3330 and 15919.
1029 2007-07-21 Eli Zaretskii <eliz@gnu.org>

1032 * function.c (func_shell): Call construct_command_argv with zero
1034 * job.c (construct_command_argv_internal): New argument FLAGS; all
1036 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore

1040 2007-07-13 Paul Smith <psmith@gnu.org>
1042 * file.c (expand_deps): Use variable_buffer as the start of the
1043 buffer, not the original pointer (in case it was reallocated).
1044 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1045 Fixes Savannah bug #20452.
1047 2007-07-04 Paul Smith <psmith@gnu.org>
1049 * (ALL FILES): Update to GPLv3.
1050 * (ALL FILES): Update copyright for 2007.

1065 reading_file rather than setting it to 0 at the end.
1066 Fixes Savannah bug #20033.
1068 2007-05-11 Paul Smith <psmith@gnu.org>
1070 * job.c (new_job): Add debug info to specify where make found the
1071 command script it is running to build a target.
1072 Fixes Savannah bug #18617.
1074 * default.c (default_suffixes,default_suffix_rules,default_variables):
1075 Add support for Objective C. Fixes Savannah bug #16389.
1076 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.

1080 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1081 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1082 Dave Korn <dave.korn@artimi.com>
1084 2007-05-08 Paul Smith <psmith@gnu.org>
1086 Fix Savannah bug #19656:
1088 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1090 * make.h: Change all case-insensitive string compares to use
1091 strcasecmp() (from POSIX). If we don't have that but do have one
1092 of the others, define strcasecmp to be one of those instead. If
1093 we don't have any, declare a prototype for our own version.
1095 * misc.c (strcasecmp): Use this if we can't find any native
1096 case-insensitive string comparison function.
1097 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1098 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1100 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1101 strcasecmp() instead of stricmp().
1102 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1103 instead of strcmpi().
1104 * acinclude.m4: Remove the strcasecmp() check from here.
1106 2007-03-21 Paul Smith <psmith@gnu.org>
1108 * configure.in: Don't turn on case-insensitive file system support
1109 if --disable-... is given. Fixes Savannah bug #19348.
1111 2007-03-19 Paul Smith <psmith@gnu.org>
1113 * ALL: Use the strcache for all file name strings, or other
1114 strings which we will never free. The goal is to save memory by
1115 avoiding duplicate copies of strings. However, at the moment this
1116 doesn't save much memory in most situations: due to secondary
1117 expansion we actually save prerequisite lists twice (once before
1118 the secondary expansion, and then again after it's been parsed
1119 into individual file names in the dep list). We will resolve this
1120 in a future change, by doing the parsing up-front for targets
1121 where secondary expansion is not set.
1123 Moving things into the strcache also allows us to use const
1124 pointers in many more places.
1126 2007-01-03 Paul Smith <psmith@gnu.org>
1128 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1129 the function, not just the first. Fixes Savannah bug #18680.
1131 2006-11-18 Paul Smith <psmith@gnu.org>
1133 * strcache.c (strcache_add_len): Don't allocate a new buffer
1134 unless the string is not already nil-terminated. Technically this
1135 is a violation of the standard, since we may be passed an array
1136 that is not long enough to test one past. However, in make this
1137 is never true since we only use nil-terminated strings or
1138 sub-strings thereof.
1140 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1142 * main.c: New global cmd_prefix, defaults to '\t'.
1143 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1146 * dir.c: Constified.
1147 (dir_contents_file_exists_p): Check for an error return from
1148 readdir(), just in case.
1150 * commands.c: Constified.
1151 * default.c: Constified.
1152 * expand.c: Constified.
1153 * function.c: Partial constification.

1158 * w32/pathstuff.c: Partial constification.
1160 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1162 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1163 backslashes and drive letters as absolute.
1165 2006-10-22 Paul Smith <psmith@gnu.org>

1169 2006-10-21 Paul Smith <psmith@gnu.org>
1172 * arscan.c: Constified.
1174 2006-09-30 Paul Smith <psmith@gnu.org>
1176 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1177 point to lastword since the example was updated.
1178 Fixes Savannah bug #16304.
1179 (Secondary Expansion): Correct example description.
1180 Fixes Savannah bug #16468.
1181 (Makefile Contents): Clarify that comments cannot appear within
1182 variable references or function calls.
1183 Fixes Savannah bug #16577.
1184 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1185 Fixes Savannah bug #17701.
1186 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1188 prerequisites. Fixes Savannah bug #17880.
1189 (Rule Syntax): "lise" -> "list"
1190 (Multiple Rules): ... -> @dots{}
1191 (Splitting Lines): ditto.
1193 * remake.c (update_file_1): Prereqs that don't exist should be
1194 considered changed, for the purposes of $?.
1195 Fixes Savannah bug #16051.

1237 that don't have extended grep.
1238 (cvsclean): Use $(PERL) instead of perl.
1240 2006-04-09 Paul D. Smith <psmith@gnu.org>
1242 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1244 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1245 inner-scope variables don't mask outer-scope variables.
1247 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1250 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1251 values from memory allocation functions: they return void* and so
1252 don't need to be cast. Also remove (char *) casts of arguments to

1306 Declare and define sh_chars_sh[].
1308 2006-03-23 Paul D. Smith <psmith@gnu.org>
1310 * configure.in: Look for build.sh.in in $srcdir so it will be
1311 built for remote configurations as well.
1313 * Makefile.am: Make sure to clean up build.sh during distclean.
1314 Fixes Savannah bug #16166.
1316 * misc.c (log_access): Takes a const char *.

1318 Both fixes for Savannah bug #16170.
1320 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1322 * implicit.c (pattern_search): Call set_file_variables only
1323 if we have prerequisites that need second expansion. Fixes
1324 Savannah bug #16140.
1326 2006-03-19 Paul D. Smith <psmith@gnu.org>
1328 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1329 memory on hosts that don't support it directly.

1332 make sure I don't forget any).
1334 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1336 (die): Cleanup code was removed from here; call the new function.
1337 (main): If we are re-execing, clean up the jobserver first so we
1338 don't leak file descriptors.

1344 allow multiple concurrent runs.
1345 Patch from Joseph Myers <joseph@codesourcery.com>
1347 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1349 * dep.h (struct dep): Add the stem field.
1350 * misc.c (alloc_dep, free_dep): New functions.
1351 (copy_dep_chain): Copy stem.
1352 (free_dep_chain): Use free_dep.
1353 * read.c (record_files): Store stem in the dependency line.
1354 * file.c (expand_deps): Use stem stored in the dependency line. Use
1355 free_dep_chain instead of free_ns_chain.
1356 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1357 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1367 (allocated_variable_append): Don't expand the final result.
1368 Fixes Savannah bug #15913.
1370 2006-03-09 Paul Smith <psmith@gnu.org>
1372 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1373 listed non-existent files as changed. Turns out there's a bug in
1374 the Linux kernel builds which means that this change causes
1375 everything to rebuild every time. We will re-introduce this fix
1376 in the next release, to give them time to fix their build system.
1377 Fixes Savannah bug #16002.
1378 Introduces Savannah bug #16051.

1395 2006-02-19 Paul D. Smith <psmith@gnu.org>
1397 * commands.c (set_file_variables): Realloc, not malloc, the static
1398 string values to avoid memory leaks.
1400 * expand.c (recursively_expand_for_file): Only set reading_file to
1401 an initialized value.
1403 * implicit.c (pattern_search): We need to make a copy of the stem
1404 if we get it from an intermediate dep, since those get freed.
1406 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1408 (enter_file) [VMS]: Ditto.

1413 * job.c (construct_command_argv_internal): Fix last change.
1415 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1416 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1417 the calls to _beginthreadex.
1419 * expand.c (recursively_expand_for_file): Initialize `save' to
1420 prevent compiler warnings.
1422 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1424 * job.c (construct_command_argv_internal): Don't create a temporary
1425 script/batch file if we are under -n. Call _setmode to switch the
1426 script file stream to text mode.
1428 2006-02-17 Paul D. Smith <psmith@gnu.org>
1430 * variable.c (merge_variable_set_lists): Don't try to merge the
1431 global_setlist. Not only is this useless, but it can lead to
1432 circularities in the linked list, if global_setlist->next in one
1433 list gets set to point to another list which also ends in
1435 Fixes Savannah bug #15757.
1437 2006-02-15 Paul D. Smith <psmith@gnu.org>
1439 Fix for Savannah bug #106.
1441 * expand.c (expanding_var): Keep track of which variable we're
1442 expanding. If no variable is being expanded, it's the same as
1444 * make.h (expanding_var): Declare it.
1445 * expand.c (recursively_expand_for_file): Set expanding_var to the
1446 current variable we're expanding, unless there's no file info in
1447 it (could happen if it comes from the command line or a default
1448 variable). Restore it before we exit.
1449 * expand.c (variable_expand_string): Use the expanding_var file
1450 info instead of the reading_file info.

1460 * read.c (eval): Even if the included filenames expands to the
1461 empty string we still need to free the allocated buffer.
1463 * implicit.c (pattern_search): If we allocated a variable set for
1464 an impossible file, free it.
1465 * variable.c (free_variable_set): New function.
1466 * variable.h: Declare it.
1468 * read.c (read_all_makefiles): Makefile names are kept in the
1469 strcache, so there's never any need to alloc/free them.
1472 * main.c (main): Add "archives" to the .FEATURES variable if
1473 archive support is enabled.
1474 * doc/make.texi (Special Variables): Document it.
1476 2006-02-13 Paul D. Smith <psmith@gnu.org>

1484 * (ALL FILES): Updated copyright and license notices.
1486 2006-02-10 Paul D. Smith <psmith@gnu.org>
1488 A new internal capability: the string cache is a read-only cache
1489 of strings, with a hash table interface for fast lookup. Nothing
1490 in the cache will ever be freed, so there's no need for reference
1491 counting, etc. This is the beginning of a full solution for
1492 Savannah bug #15182, but for now we only store makefile names here.
1494 * strcache.c: New file. Implement a read-only string cache.
1495 * make.h: Add prototypes for new functions.
1496 * main.c (initialize_global_hash_tables): Initialize the string cache.
1497 (print_data_base): Print string cache stats.
1498 * read.c (eval_makefile): Use the string cache to store makefile
1499 names. Rewrite the string allocation to be sure we free everything.
1501 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1503 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1504 directory time stamp didn't change, except on FAT filesystems.

1510 (func_and): Implement a short-circuiting AND function.
1511 (function_table_init): Update the table with the new functions.
1512 * doc/make.texi (Conditional Functions): Changed the "if" section
1513 to one on general conditional functions. Added documentation for
1514 $(and ...) and $(or ...) functions.

1527 timestamp from -o or -W, use that instead of the real time.

1529 -W, don't overwrite it with the real mtime.

1547 Fixes Savannah bug #15533.
1548 * filedef.h (struct file): Add a new LAST pointer.
1550 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1551 the comparison. For 64-bits systems the result of the subtraction
1552 might not fit into an int. Use comparison instead.
1553 Fixes Savannah bug #15534.
1555 * doc/make.texi: Update the chapter on writing commands to reflect
1556 the changes made in 3.81 for backslash/newline and SHELL handling.
1558 2006-02-01 Paul D. Smith <psmith@gnu.org>
1560 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1561 variable st is not used when it's not initialized.
1562 Patch from Eli Zaretskii <eliz@gnu.org>.

1574 * prepare_w32.bat: Remove this file from the distribution.
1576 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1578 * remake.c (update_goal_chain): Set g->changed instead of
1579 incrementing it, as it is only 8-bit wide, and could overflow if
1580 many commands got started in update_file.

1584 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1585 MAXIMUM_WAIT_OBJECTS.

1594 are already more children than sub_proc.c can handle, behave as if
1595 the load were too high.
1596 (start_job_command): Fix a typo in error message when process_easy
1599 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1601 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1602 the shell is not sh.exe.
1604 * job.c (create_batch_file): Renamed from create_batch_filename;
1605 all callers changed. Don't close the temporary file; return its
1606 file descriptor instead. New arg FD allows to return the file
1608 (construct_command_argv_internal): Use _fdopen instead of fopen to
1609 open the batch file.
1611 2006-01-04 Paul D. Smith <psmith@gnu.org>
1613 * readme.vms: Updates for case-insensitive VMS file systems from
1614 Hartmut Becker <Hartmut.Becker@hp.com>.
1615 * dir.c (vms_hash): Ditto.
1616 * vmsify.c (copyto): Ditto.
1617 * vmsfunctions.c (readdir): Ditto.
1619 * make.1: Add a section on the exit codes for make.
1621 * doc/make.texi: A number of minor updates to the documentation.
1623 2006-01-03 Paul D. Smith <psmith@gnu.org>
1625 * remake.c (update_file_1): Mark a prerequisite changed if it
1628 * read.c (eval): Be sure to strip off trailing whitespace from the
1629 prerequisites list properly. Also, initialize all fields in
1630 struct dep when creating a new one.
1632 2005-12-28 Paul D. Smith <psmith@gnu.org>
1634 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1635 disable warnings for MSC.
1636 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1638 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1640 * doc/make.texi (Execution): Add a footnote about changes in
1641 handling of backslash-newline sequences. Mention the differences
1642 on MS-DOS and MS-Windows.
1644 * NEWS: More details about building the MinGW port and a pointer
1645 to README.W32. Fix the section name that describes the new
1646 backward-incompatible processing of backslash-newline sequences.
1647 The special processing of SHELL set to "cmd" is only relevant to
1648 MS-Windows, not MS-DOS.
1650 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1652 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1653 to DWORD, to avoid compiler warnings.
1654 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1655 use %ld in format, to avoid compiler warnings.
1657 * doc/make.texi (Special Targets): Fix a typo.
1658 (Appending): Fix cross-reference to Setting.
1659 (Special Variables, Secondary Expansion, File Name Functions)
1660 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1661 periods after a sentence.
1662 (Execution): Add @: after "e.g.".
1663 (Environment): Fix punctuation.
1664 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1665 (Shell Function, Target-specific): Add @: after "vs."
1667 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1669 * read.c (record_target_var): Initialize variable's export field
1670 with v_default instead of leaving it "initialized" by whatever
1671 garbage happened to be on the heap.
1673 2005-12-12 Paul D. Smith <psmith@gnu.org>
1675 * make.1: Fix some display errors and document all existing options.
1676 Patch by Mike Frysinger <vapier@gentoo.org>.
1678 2005-12-11 Paul D. Smith <psmith@gnu.org>
1680 * implicit.c (pattern_search): If 2nd expansion is not set for
1681 this implicit rule, replace the pattern with the stem directly,
1682 and don't re-expand the variable list. Along with the other
1683 .SECONDEXPANSION changes below, fixes bug #13781.
1685 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1687 * implicit.c (pattern_search): Mark other files that this rule
1688 builds as targets so that they are not treated as intermediates
1689 by the pattern rule search algorithm. Fixes bug #13022.
1691 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1693 * remake.c (notice_finished_file): Propagate the change of
1694 modification time to all the double-colon entries only if
1695 it is the last one to be updated. Fixes bug #14334.
1697 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1699 * function.c (func_flavor): Implement the flavor function which
1700 returns the flavor of a variable.
1701 * doc/make.texi (Functions for Transforming Text): Document it.
1702 * NEWS: Add it to the list of new functions.
1704 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1706 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1708 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1709 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1711 2005-10-26 Paul Smith <psmith@gnu.org>
1713 * read.c (record_files): Don't set deps flags if there are no deps.
1714 * maintMakefile: We only need to build the templates when we are
1715 creating a distribution, so don't do it for "all".
1717 2005-10-24 Paul D. Smith <psmith@gnu.org>
1719 Make secondary expansion optional: its enabled by declaring the
1720 special target .SECONDEXPANSION.
1722 * NEWS: Update information on second expansion capabilities.
1723 * doc/make.texi (Secondary Expansion): Document the
1724 .SECONDEXPANSION special target and its behavior.
1725 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1726 prerequisite list was found in a static pattern rule.
1727 (free_dep_chain): Declare a prototype.
1728 * file.c (parse_prereqs): New function: break out some complexity
1730 (expand_deps): If we aren't doing second expansion, replace % with
1731 the stem for static pattern rules. Call the new function.
1732 * filedef.h (parse_prereqs): Declare a prototype.
1733 * implicit.c (pattern_search): Initialize the new staticpattern
1735 * main.c (second_expansion): Declare a global variable to remember
1736 if the special target has been seen. Initialize the new
1737 staticpattern field for prerequisites.
1738 * make.h: Extern for second_expansion.
1739 * misc.c (free_dep_chain): New function: frees a struct dep list.
1740 * read.c (read_all_makefiles): Initialize the staticpattern field.
1741 (eval_makefile): Ditto.
1742 (record_files): Check for the .SECONDEXPANSION target and set
1743 second_expansion global if it's found.
1744 Use the new free_dep_chain() instead of doing it by hand.
1745 Set the staticpattern field for prereqs of static pattern targets.
1747 2005-10-16 Paul D. Smith <psmith@gnu.org>
1749 * main.c (main): Set CURDIR to be a file variable instead of a
1750 default, so that values of CURDIR inherited from the environment
1751 won't override the make value.
1753 2005-09-26 Paul D. Smith <psmith@gnu.org>
1755 * job.c (construct_command_argv_internal): If the line is empty
1756 remember to free the temporary argv strings.
1759 2005-09-16 Paul D. Smith <psmith@gnu.org>
1761 * job.c (start_job_command): The noerror flag is a boolean (single
1762 bit); set it appropriately.
1763 Reported by Mark Eichin <eichin@metacarta.com>
1765 2005-08-29 Paul D. Smith <psmith@gnu.org>
1767 * function.c (func_error): On Windows, output from $(info ...)
1768 seems to come in the wrong order. Try to force it with fflush().
1770 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1772 * read.c (record_files): Move code that sets stem for static
1773 pattern rules out of the if (!two_colon) condition so it is
1774 also executed for two-colon rules. Fixes Savannah bug #13881.
1776 2005-08-08 Paul D. Smith <psmith@gnu.org>
1778 * make.h: Don't test that __STDC__ is non-0. Some compilers
1779 (Windows for example) set it to 0 to denote "ISO C + extensions".
1782 2005-08-07 Paul D. Smith <psmith@gnu.org>
1784 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1785 conditional (slightly different version of a fix from Eli).
1787 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1788 If make is running in parallel without -k and two jobs die in a
1789 row, but not too close to each other, then make will quit without
1790 waiting for the rest of the jobs to die.
1792 * main.c (die): Don't reset err before calling reap_children() the
1793 second time: we still want it to be in the error condition.
1794 * job.c (reap_children): Use a static variable, rather than err,
1795 to control whether or not the error message should be printed.
1797 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1799 * w32/subproc/sub_proc.c: Include signal.h.
1800 (process_pipe_io, process_file_io): Pass a pointer to a local
1801 DWORD variable to GetExitCodeProcess. If the exit code is
1802 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1804 * job.c [WINDOWS32]: Include windows.h.
1805 (main_thread) [WINDOWS32]: New global variable.
1806 (reap_children) [WINDOWS32]: Get the handle for the main thread
1807 and store it in main_thread.
1809 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1810 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1811 doing anything else. When we are done, close the main thread
1812 handle and exit with status 130.
1814 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1816 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1819 * main.c (find_and_set_default_shell): If found a DOSish shell,
1820 set sh_found and the value of default_shell, and report the
1821 findings in debug mode.
1823 * job.c (construct_command_argv_internal): Check unixy_shell, not
1824 no_default_sh_exe, to decide whether to use Unixy or DOSish
1827 * README.W32: Update with info about the MinGW build.
1829 * build_w32.bat: Support MinGW.
1831 * w32/subproc/build.bat: Likewise.
1833 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1834 printing DWORD args.
1836 * function.c (windows32_openpipe): Fix format strings for printing
1839 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1841 (start_job_command): Fix format string for printing the result of
1843 (start_job_command) [WINDOWS32]: Do not define.
1844 (exec_command): Fix format string for printing HANDLE args.
1846 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1847 to avoid compiler warnings.
1848 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1849 (Note: some of these fixes were submitted independently by J. Grant)
1851 2005-07-30 J. Grant <jg@jguk.org>
1853 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1854 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1855 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1857 2005-07-15 Paul Smith <psmith@gnu.org>
1859 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1860 we don't have a POSIX shell, then revert to the old
1861 backslash-newline behavior (where they are stripped).
1864 2005-07-08 Paul D. Smith <psmith@gnu.org>
1866 * config.h.W32.template: Reorder to match the standard config.h,
1867 for easier comparisons.
1868 From J. Grant <jg@jguk.org>
1870 * maintMakefile: Remove .dep_segment before overwriting it, in
1871 case it's not writable or noclobber is set.
1872 * expand.c (variable_expand_string): Cast result of pointer
1873 arithmetic to avoid a warning.
1874 * main.c (switches): Add full-fledged final initializer.
1876 2005-07-06 Paul D. Smith <psmith@gnu.org>
1878 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1879 * signame.c (strsignal): If we found _sys_siglist[] or
1880 __sys_siglist[] use those instead of sys_siglist[].
1881 From Albert Chin <china@thewrittenword.com>
1883 2005-07-04 Paul D. Smith <psmith@gnu.org>
1885 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1886 globfree(); set up to use the GNU versions.
1887 From Martin Zinser <zinser@zinser.no-ip.info>
1889 2005-07-03 Paul D. Smith <psmith@gnu.org>
1891 From J. Grant <jg@jguk.org>:
1893 * README.W32.template: Update the Windows and tested MSVC versions.
1894 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1895 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1896 * build_w32.bat: Ditto.
1897 * w32/subproc/build.bat: Ditto.
1899 2005-06-28 Paul D. Smith <psmith@gnu.org>
1901 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1902 declaration was checked but not present.
1904 2005-06-27 Paul D. Smith <psmith@gnu.org>
1906 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1907 to unsigned long. Fixes Savannah bug #13550.
1909 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1910 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1911 Fixes Savannah bug #13551.
1913 2005-06-26 Paul D. Smith <psmith@gnu.org>
1915 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1916 it if ANSI_STRING is not set.
1918 2005-06-25 Paul D. Smith <psmith@gnu.org>
1920 * read.c (eval): If no filenames are passed to any of the
1921 "include" variants, don't print an error.
1922 * doc/make.texi (Include): Document this.
1923 Fixes Savannah bug #1761.
1925 * job.c (construct_command_argv_internal): Sanitize handling of
1926 backslash/newline pairs according to POSIX: that is, keep the
1927 backslash-newline in the command script, but remove a following
1928 TAB character, if present. In the fast path, make sure that the
1929 behavior matches what the shell would do both inside and outside
1930 of quotes. In the slow path, quote the backslash and put a
1931 literal newline in the string.
1932 Fixes Savannah bug #1332.
1933 * doc/make.texi (Execution): Document the new behavior and give
1935 * NEWS: Make a note of the new behavior.
1937 * make.h [WINDOWS32]: #include <direct.h>.
1938 Fixes Savannah bug #13478.
1940 * remake.c (name_mtime): If the stat() of a file fails and the -L
1941 option was given and the file is a symlink, take the best mtime of
1942 the symlink we can get as the mtime of the file and don't fail.
1943 Fixes Savannah bug #13280.
1945 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1946 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1947 inside a variable reference. Make this function static as it's
1949 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1950 parsing an unexpanded line looking for semicolons.
1951 Fixes Savannah bug #1454.
1952 * misc.c (remove_comments): Move this to read.c and make it static
1953 as it's only used there. Call find_char_unquote() with new arg.
1954 * make.h: Remove prototypes for find_char_unquote() and
1955 remove_comments() since they're static now.
1957 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1958 its export flag and obtain its value. When we need to re-exec,
1959 increment the value and add it into the environment.
1960 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1961 * NEWS: Mention MAKE_RESTARTS.
1962 * main.c (always_make_set): New variable. Change the -B option to
1963 set this one instead.
1964 (main): When checking makefiles, only set always_make_flag if
1965 always_make_set is set AND the restarts flag is 0. When building
1966 normal targets, set it IFF always_make_set is set.
1967 (main): Avoid infinite recursion with -W, too: only set what-if
1968 files to NEW before we check makefiles if we've never restarted
1969 before. If we have restarted, set what-if files to NEW _after_ we
1971 Fixes Savannah bug #7566:
1973 2005-06-17 Paul D. Smith <psmith@gnu.org>
1975 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1976 in the prerequisites list.
1978 2005-06-12 Paul D. Smith <psmith@gnu.org>
1980 Fix Savannah bug # 1328.
1982 * configure.in: Check for atexit().
1983 * misc.c (close_stdout): Test stdout to see if writes to it have
1984 failed. If so, be sure to exit with a non-0 error code. Based on
1985 code found in gnulib.
1986 * make.h: Prototype.
1987 * main.c (main): Install close_stdout() with atexit().
1989 2005-06-10 Paul D. Smith <psmith@gnu.org>
1991 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1993 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1994 headers; make vmsWaitForChildren() static; extern vmsify().
1995 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1996 Don't create child_execute_job() here (it's in vmsjobs.c).
1997 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1999 2005-06-09 Paul D. Smith <psmith@gnu.org>
2001 * variable.c (push_new_variable_scope): File variables point
2002 directly to the global_setlist variable. So, inserting a new
2003 scope in front of that has no effect on those variables: they
2004 don't go through current_variable_set_list. If we're pushing a
2005 scope and the current scope is global, push it "the other way" so
2006 that the new setlist is in the global_setlist variable, and
2007 next points to a new setlist with the global variable set.
2008 (pop_variable_scope): Properly undo a push with the new
2010 Fixes Savannah bug #11913.
2012 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2014 * job.c (reap_children): Don't die of the command failed but
2015 the dontcare flag is set. Fixes Savannah bug #13216.
2017 * implicit.c (pattern_search): When creating a target from
2018 an implicit rule match, lookup pattern target and set precious
2019 flag in a newly created target. Fixes Savannah bug #13218.
2021 2005-05-13 Paul D. Smith <psmith@gnu.org>
2023 Implement "if... else if... endif" syntax.
2025 * read.c (eval): Push all checks for conditional words ("ifeq",
2026 "else", etc.) down into the conditional_line() function.
2027 (conditional_line): Rework to allow "else if..." clause. New
2028 return value -2 for lines which are not conditionals. The
2029 ignoring flag can now also be 2, which means "already parsed a
2030 true branch". If that value is seen no other branch of this
2031 conditional can be considered true. In the else parsing if there
2032 is extra text after the else, invoke conditional_line()
2033 recursively to see if it's another conditional. If not, it's an
2034 error. If so, raise the conditional value to this level instead
2035 of creating a new conditional nesting level. Special check for
2036 "else" and "endif", which aren't allowed on the "else" line.
2037 * doc/make.texi (Conditional Syntax): Document the new syntax.
2039 2005-05-09 Paul D. Smith <psmith@gnu.org>
2041 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2042 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2043 recurses to the w32 directory, even on non-Windows systems. Use
2044 the method suggested in the automake manual.
2045 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2046 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2048 2005-05-07 Paul D. Smith <psmith@gnu.org>
2050 * main.c (die): If we're dying with a fatal error (not that a
2051 command has failed), write back any leftover tokens before we go.
2053 * job.c (set_child_handler_action_flags): If there are jobs
2054 waiting for the load to go down, set an alarm to go off in 1
2055 second. This allows us to wake up from a potentially long-lasting
2056 read() and start a new job if the load has gone down. Turn it off
2058 (job_noop): Dummy signal handler function.
2059 (new_job): Invoke it with the new semantics.
2061 * docs/make.texi: Document secondary expansion. Various cleanups
2064 2005-05-03 Paul D. Smith <psmith@gnu.org>
2066 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2067 the targets which are to ultimately be made are called "goals";
2068 see the GNU make manual. Also, MAKECMDGOALS, etc.
2070 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2071 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2072 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2074 2005-05-02 Paul D. Smith <psmith@gnu.org>
2076 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2077 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2078 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2079 functions to vmsjobs.c. #include it into jobs.c.
2081 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2082 jobserver tokens. I found that this happens when an exported
2083 recursive variable contains a $(shell ...) function reference: in
2084 this situation we could "forget" to write back a token.
2086 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2087 we have. It's not reliable to depend on the number of children in
2088 our linked list so keep a separate count.
2089 (new_job): Check jobserver_tokens rather than children &&
2090 waiting_jobs. Increment jobserver_tokens when we get one.
2091 (free_child): If jobserver_tokens is 0, internal error. If it's
2092 >1, write a token back to the jobserver pipe (we don't write a
2093 token for the "free" job). Decrement jobserver_tokens.
2095 * main.c: Add variable master_job_slots.
2096 (main): Set it to hold the number of jobs requested if we're the
2097 master process, when using the jobserver.
2098 (die): Sanity checks: first test jobserver_tokens to make sure
2099 this process isn't holding any tokens we didn't write back.
2100 Second, if master_job_slots is set count the tokens left in the
2101 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2103 2005-04-24 Paul D. Smith <psmith@gnu.org>
2105 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2106 with -l# can lose jobserver tokens, because waiting jobs are not
2107 consulted properly when checking for the "free" token.
2109 * job.c (free_child): Count waiting_jobs as having tokens.
2110 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2111 handle jobs waiting for the load to drop.
2113 2005-04-23 Paul D. Smith <psmith@gnu.org>
2115 * main.c (main): Be careful to not core if a variable setting in
2116 the environment doesn't contain an '='. This is illegal but can
2117 happen in broken setups.
2118 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2120 2005-04-12 Paul D. Smith <psmith@gnu.org>
2122 The second expansion feature causes significant slowdown. Timing
2123 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2124 read the makefile before the feature, to 11+s to do the same
2125 operations after the feature. Additionally, memory usage
2126 increased drastically. To fix this I added some intelligence that
2127 avoids the overhead of the second expansion unless it's required.
2129 * dep.h: Add a new boolean field, need_2nd_expansion.
2131 * read.c (eval): When creating the struct dep for the target,
2132 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2133 (record_files): If there's a "%" in a static pattern rule, it gets
2134 converted to "$*" so set need_2nd_expansion to 1.
2136 * file.c (expand_deps): Rework to be more efficient. Only perform
2137 initialize_file_variables(), set_file_variables(), and
2138 variable_expand_for_file() if the need_2nd_expansion is set.
2140 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2141 (pattern_search): Ditto.
2142 * main.c (handle_non_switch_argument): Ditto.
2144 * read.c (read_all_makefiles): Ditto.
2145 (eval_makefile): Ditto.
2147 2005-04-07 Paul D. Smith <psmith@gnu.org>
2149 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2150 * variable.c (sync_Path_environment): Ditto.
2151 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2153 * main.c (main): Define the .FEATURES variable.
2154 * NEWS: Announce .FEATURES.
2155 * doc/make.texi (Special Variables): Document .FEATURES.
2157 * remake.c (check_dep): If a file is .PHONY, update it even if
2158 it's marked intermediate. Fixes Savannah bug #12331.
2160 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2162 * file.c (expand_deps): Factor out the second expansion and
2163 prerequisite line parsing logic from snap_deps().
2165 * file.c (snap_deps): Use expand_deps(). Expand and parse
2166 prerequisites of the .SUFFIXES special target first. Fixes
2167 Savannah bug #12320.
2169 2005-03-13 Paul D. Smith <psmith@gnu.org>
2171 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2174 2005-03-11 Paul D. Smith <psmith@gnu.org>
2176 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2177 available, not undefined (from Earnie Boyd).
2179 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2181 * implicit.c (pattern_search): Mark an intermediate target as
2182 precious if it happened to be a prerequisite of some (other)
2183 target. Fixes Savannah bug #12267.
2185 2005-03-09 Paul D. Smith <psmith@gnu.org>
2187 * read.c (eval_makefile): Add alloca(0).
2188 (eval_buffer): Ditto.
2190 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2192 * main.c (main): Use o_file instead of o_default when defining
2193 the .DEFAULT_TARGET special variable.
2194 * read.c (eval): Use define_variable_global() instead of
2195 define_variable() when setting new value for the .DEFAULT_TARGET
2196 special variable. Fixes Savannah bug #12266.
2198 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2200 * imlicit.c (pattern_search): Mark files for which an implicit
2201 rule has been found as targets. Fixes Savannah bug #12202.
2203 2005-03-04 Paul D. Smith <psmith@gnu.org>
2206 * doc/make.texi (Automatic Variables): Document $|.
2208 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2210 * read.c (record_files): Instead of substituting % with
2211 actual stem value in dependency list replace it with $*.
2212 This fixes stem triple expansion bug.
2214 * implicit.c (pattern_search): Copy stem to a separate
2215 buffer and make it a properly terminated string. Assign
2216 this buffer instead of STEM (which is not terminated) to
2217 f->stem. Instead of substituting % with actual stem value
2218 in dependency list replace it with $*. This fixes stem
2219 triple expansion bug.
2221 2005-03-01 Paul D. Smith <psmith@gnu.org>
2223 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2224 on Windows, as it takes a handle not a pid. Just exit.
2225 Fix from patch #3679, provided by Alessandro Vesely.
2227 * configure.in: Update check for sys_siglist[] from autoconf manual.
2228 * signame.c (strsignal): Update to use the new autoconf macro.
2230 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2232 * read.c (record_files): Add a check for the list of prerequisites
2233 of a static pattern rule being empty. Fixes Savannah bug #12180.
2235 2005-02-28 Paul D. Smith <psmith@gnu.org>
2237 * doc/make.texi (Text Functions): Update docs to allow the end
2238 ordinal for $(wordlist ...) to be 0.
2239 * function.c (func_wordlist): Fail if the start ordinal for
2240 $(wordlist ...) is <1. Matches documentation.
2241 Resolves Savannah support request #103195.
2243 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2244 previously we were stopping when !-q, exactly the opposite. This
2245 has been wrong since version 1.34, in 1994!
2246 (update_file): If we got an error don't break out to run more
2247 double-colon rules: just return immediately.
2248 Fixes Savannah bug #7144.
2250 2005-02-27 Paul D. Smith <psmith@gnu.org>
2252 * misc.c (end_of_token): Make argument const.
2253 * make.h: Update prototype.
2255 * function.c (abspath, func_realpath, func_abspath): Use
2256 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2257 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2258 * read.c (record_files): Ditto.
2259 * variable.c (do_variable_definition): Ditto.
2261 * function.c (func_error): Create a new function $(info ...) that
2262 simply prints the message to stdout with no extras.
2263 (function_table_init): Add new function to the table.
2264 * NEWS: Add $(info ...) reference.
2265 * doc/make.texi (Make Control Functions): Document it.
2267 New feature: if the system supports symbolic links, and the user
2268 provides the -L/--check-symlink-time flag, then use the latest
2269 mtime between the symlink(s) and the target file.
2271 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2272 readlink(). If both are available, define MAKE_SYMLINKS.
2273 * main.c: New variable: check_symlink_flag.
2274 (usage): Add a line for -L/--check-symlink-times to the help string.
2275 (switches): Add -L/--check-symlink-times command line argument.
2276 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2277 print a warning and disable it again.
2278 * make.h: Declare check_symlink_flag.
2279 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2280 if the file is a symlink then check each link in the chain and
2281 choose the NEWEST mtime we find as the mtime for the file. The
2282 newest mtime might be the file itself!
2283 * NEWS: Add information about this new feature.
2284 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2286 Avoid core dumps described in Savannah bug # 12124:
2288 * file.c: New variable snapped_deps remember whether we've run
2290 (snap_deps): Set it.
2291 * filedef.h: Extern it.
2292 * read.c (record_files): Check snapped_deps; if it's set then
2293 we're trying to eval a new target/prerequisite relationship from
2294 within a command script, which we don't support. Fatal.
2296 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2298 Implementation of the .DEFAULT_TARGET special variable.
2300 * read.c (eval): If necessary, update default_target_name when
2302 * read.c (record_files): Update default_target_file if
2303 default_target_name has changed.
2304 * main.c (default_target_name): Define.
2305 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2306 default_target_name is set use default_target_file as a root
2308 * filedef.h (default_target_name): Declare.
2309 * dep.h (free_dep_chain):
2310 * misc.c (free_dep_chain): Change to operate on struct nameseq
2311 and change name to free_ns_chain.
2312 * file.c (snap_deps): Update to use free_ns_chain.
2314 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2316 Implementation of the second expansion in explicit rules,
2317 static pattern rules and implicit rules.
2319 * read.c (eval): Refrain from chopping up rule's dependencies.
2320 Store them in a struct dep as a single dependency line. Remove
2321 the code that implements SySV-style automatic variables.
2323 * read.c (record_files): Adjust the code that handles static
2324 pattern rules to expand all percents instead of only the first
2325 one. Reverse the order in which dependencies are stored so that
2326 when the second expansion reverses them again they appear in
2327 the makefile order (with some exceptions, see comments in
2328 the code). Remove the code that implements SySV-style automatic
2331 * file.c (snap_deps): Implement the second expansion and chopping
2332 of dependency lines for explicit rules.
2334 * implicit.c (struct idep): Define an auxiliary data type to hold
2335 implicit rule's dependencies after stem substitution and
2338 * implicit.c (free_idep_chain): Implement.
2340 * implicit.c (get_next_word): Implement helper function for
2341 parsing implicit rule's dependency lines into words taking
2342 into account variable expansion requests. Used in the stem
2345 * implicit.c (pattern_search): Implement the second expansion
2346 for implicit rules. Also fixes bug #12091.
2348 * commands.h (set_file_variables): Declare.
2349 * commands.c (set_file_variables): Remove static specifier.
2351 * dep.h (free_dep_chain): Declare.
2352 * misc.c (free_dep_chain): Implement.
2354 * variable.h (variable_expand_for_file): Declare.
2355 * expand.c (variable_expand_for_file): Remove static specifier.
2357 * make.h (strip_whitespace): Declare.
2358 * function.c (strip_whitespace): Remove static specifier.
2360 2005-02-26 Paul D. Smith <psmith@gnu.org>
2362 * main.c (main): Check for ferror() when reading makefiles from stdin.
2363 Apparently some shells in Windows don't close pipes properly and
2366 2005-02-24 Jonathan Grant <jg@jguk.org>
2368 * configure.in: Add MinGW configuration options, and extra w32 code
2370 * Makefile.am: Add MinGW configuration options, and extra w32 code
2372 * main.c: Determine correct program string (after last \ without .exe).
2373 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2375 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2376 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2377 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2378 environment support.
2380 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2382 * function.c (func_shell): When initializing error_prefix, check
2383 that reading file name is not null. This fixes long-standing
2384 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2386 2005-02-09 Paul D. Smith <psmith@gnu.org>
2388 * maintMakefile: Update the CVS download URL to simplify them.
2389 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2390 downloading the .texi files from Savannah now.
2392 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2394 * main.c (handle_non_switch_argument): Only add variables to
2395 command_variables if they're not already there: duplicate settings
2396 waste space and can be confusing to read.
2398 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2399 this header is never included by non-WINDOWS32 code, and it
2400 requires <config.h> to define which isn't always included first.
2402 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2403 testing MINGW32 versions.
2405 * main.c (log_working_directory): flush stdout to be sure the WD
2406 change is printed before any stderr messages show up.
2408 2005-02-01 Paul D. Smith <psmith@gnu.org>
2410 * maintMakefile (po_repo): Update the GNU translation site URL.
2412 2004-12-01 Paul D. Smith <psmith@gnu.org>
2414 * main.c (main): Change char* env_shell to struct variable shell_var.
2415 * variable.c (target_environment): Use new shell_var.
2417 2004-11-30 Paul D. Smith <psmith@gnu.org>
2419 * configure.in: The old way we avoided creating build.sh from
2420 build.sh.in before build.sh.in exists doesn't work anymore; we
2421 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2422 the help!). This also keeps automake from complaining.
2423 * Makefile.am (README): Add a dummy target so automake won't
2424 complain that this file doesn't exist when we checkout from CVS.
2425 * maintMakefile (.dep_segment): Rewrite this rule since newer
2426 versions of automake don't provide DEP_FILES.
2428 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2430 Implementation of `realpath' and `abspath' built-in functions.
2432 * configure.in: Check for realpath.
2433 * function.c (abspath): Return an absolute file name that does
2434 not contain any `.' or `..' components, nor repeated `/'.
2435 * function.c (func_abspath): For each name call abspath.
2436 * function.c (func_realpath): For each name call realpath
2437 from libc or delegate to abspath if realpath is not available.
2438 * doc/make.texi (Functions for File Names): Document new functions.
2439 * doc/make.texi (Quick Reference): Ditto.
2441 2004-11-28 Paul D. Smith <psmith@gnu.org>
2443 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2444 arguments. Fixes bug #10252.
2446 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2448 * main.c (main): Set SHELL to v_noexport by default. Remember the
2449 original environment setting of SHELL in the env_shell variable.
2450 * main.h: Export new env_shell variable.
2451 * variable.c (target_environment): If we find a v_noexport
2452 variable for SHELL, add a SHELL variable with the env_shell value.
2453 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2454 * doc/make.texi (Variables/Recursion): Ditto.
2456 2004-11-28 Paul D. Smith <psmith@gnu.org>
2458 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2459 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2460 Patch by Alessandro Vesely.
2462 2004-11-12 Paul D. Smith <psmith@gnu.org>
2464 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2465 the command line if it's inside a string.
2466 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2468 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2470 * function.c (func_lastword): New function: return last word
2471 from the list of words.
2472 * doc/make.texi: Document $(lastword ). Fix broken links in
2473 Quick Reference section.
2475 2004-10-06 Paul D. Smith <psmith@gnu.org>
2477 Apply patch from Alessandro Vesely, provided with bug # 9748.
2478 Fix use of tmpnam() to work with Borland C.
2480 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2481 construction of a temporary filename, and call new function
2482 create_batch_filename().
2483 (create_batch_filename) [WINDOWS32]: New function to create a
2486 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2488 * read.c (record_target_var): Expand simple pattern-specific
2490 * variable.c (initialize_file_variables): Do not expand simple
2491 pattern-specific variable.
2493 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2495 * remake.c (update_file_1): When rebuilding makefiles inherit
2496 dontcare flag from a target that triggered update.
2498 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2500 * variable.c (initialize_file_variables): Mark pattern-specific
2501 variable as a per-target and copy export status.
2503 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2505 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2507 * implicit.c (pattern_search): When considering an implicit rule's
2508 prerequisite check that it is actually a target rather then
2509 just an entry in the file hashtable.
2511 2004-09-21 Paul D. Smith <psmith@gnu.org>
2513 * read.c (readstring): Fix some logic errors in backslash handling.
2514 (eval): Remove some unnecessary processing in buffer handling.
2515 (record_target_var): Assert that parse_variable_definition() succeeded.
2516 Reported by: Markus Mauhart <qwe123@chello.at>.
2518 * misc.c: Removed the sindex() function. All instances of this
2519 function were trivially replaceable by the standard strstr()
2520 function, and that function will always have better (or certainly
2521 no worse) performance than the very simple-minded algorithm
2522 sindex() used. This can matter with complex makefiles.
2523 * make.h: Remove the prototype for sindex().
2524 * function.c (subst_expand): Convert sindex() call to strstr().
2525 This means we no longer need to track the TLEN value so remove that.
2526 (func_findstring): Convert sindex() to strstr().
2527 * commands.c (chop_commands): Convert sindex() calls to strstr().
2528 Suggested by: Markus Mauhart <qwe123@chello.at>.
2530 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2531 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2532 If SHELL is set to CMD.EXE then assume it's batch-mode and
2533 non-unixy. I wrote the code differently from the patch, though,
2534 to make it safer. This also resolves bug #9174.
2536 2004-09-20 Paul D. Smith <psmith@gnu.org>
2538 * expand.c (variable_expand_string): Modify to invoke
2539 patsubst_expand() instead of subst_expand(); the latter didn't
2540 handle suffix patterns correctly.
2541 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2542 was used only from variable_expand_string() and is no longer used
2544 (func_subst): Ditto, on call to subst_expand().
2545 (patsubst_expand): Require the percent pointers to point to the
2546 character after the %, not to the % itself.
2547 * read.c (record_files): New call criteria for patsubst_expand().
2548 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2549 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2551 2004-09-19 Paul D. Smith <psmith@gnu.org>
2553 * function.c (subst_expand): Fix a check in by_word: look for a
2554 previous blank if we're beyond the beginning of the string, not
2555 the beginning of the word.
2556 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2558 2004-05-16 Paul D. Smith <psmith@gnu.org>
2560 * remake.c (update_goal_chain): Change the argument specifying
2561 whether we're rebuilding makefiles to be a global variable,
2562 REBUILDING_MAKEFILES.
2563 (complain): Extract the code that complains about no rules to make
2564 a target into a separate function.
2565 (update_file_1): If we tried to rebuild a file during the makefile
2566 rebuild phase and it was dontcare, then no message was printed.
2567 If we then try to build the same file during the normal build,
2568 print a message this time.
2569 (remake_file): Don't complain about un-remake-able files when
2570 we're rebuilding makefiles.
2572 2004-05-11 Paul D. Smith <psmith@gnu.org>
2574 * job.c (construct_command_argv_internal): OS/2 patches from
2575 Andreas Buening <andreas.buening@nexgo.de>.
2577 2004-05-10 Paul D. Smith <psmith@gnu.org>
2579 * remake.c (update_file): Don't walk the double-colon chain unless
2580 this is a double-colon rule. Fix suggested by Boris Kolpackov
2581 <boris@kolpackov.net>.
2583 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2584 * readme.vms: New section describing OpenVMS support and issues.
2585 * default.c (default_variables): Add support for IA64.
2586 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2587 without some privilege aborts make with the error
2588 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2589 pressing Ctrl+Y and the input device is no terminal. The change
2590 catches this error and just continues.
2592 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2594 2004-04-25 Paul D. Smith <psmith@gnu.org>
2596 * commands.c (set_file_variables): Set $< properly in the face of
2597 order-only prerequisites.
2598 Patch from Boris Kolpackov <boris@kolpackov.net>
2600 2004-04-21 Bob Byrnes <byrnes@curl.com>
2602 * main.c (main): Notice failures to remake makefiles.
2604 2004-03-28 Paul D. Smith <psmith@gnu.org>
2606 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2608 * job.c: No default shell for RISC OS.
2609 (load_too_high): Hard-code the return to 1.
2610 (construct_command_argv_internal): No sh_chars or sh_cmds.
2611 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2613 2004-03-20 Paul D. Smith <psmith@gnu.org>
2615 * variable.c (do_variable_definition): Don't append from the
2616 global set if a previous non-appending target-specific variable
2617 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2620 * expand.c (reference_variable): Don't give up on variables with
2621 no value that have the target-specific append flag set: they might
2622 have a value after all. Reported by Oliver Schmidt
2623 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2624 <nikulin@dx1cmd.inp.nsk.su>.
2626 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2627 refer to absolute pathnames in directories that don't exist: some
2628 portion of the makefile could create those directories before we
2629 match the pattern. Fixes bugs #775 and #108.
2631 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2633 * main.c (main): Free makefile_mtimes if we have any.
2634 * README.W32.template: Update documentation for the current status
2635 of the MS-Windows port.
2636 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2637 environment variable is sometimes already defined which causes the
2639 * main.c (debug_signal_handler): Only define this function if
2640 SIGUSR1 is available.
2642 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2644 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2645 * README.OS2.template: Documentation updates.
2646 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2647 link line for safety.
2648 * maintMakefile (build.sh.in): Remove an extraneous ")".
2649 * job.c (child_execute_job): Close saved FDs.
2650 * job.c (exec_command) [OS/2]: exec_command(): If the command
2651 can't be exec'ed and if the shell is not Unix-sh, then try again
2652 with argv = { "cmd", "/c", ... }. Normally, this code is never
2653 reached for the cmd shell unless the command really doesn't exist.
2654 (construct_command_argv_internal) [OS/2]: The code for cmd
2655 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2656 The CMD builtin commands are case insensitive so use strcasecmp().
2658 2004-03-19 Paul D. Smith <psmith@gnu.org>
2660 * read.c (do_define): Re-order line counter increment so the count
2661 is accurate (we were losing one line per define). Reported by
2662 Dave Yost <Dave@Yost.com>.
2664 2004-03-06 Paul D. Smith <psmith@gnu.org>
2666 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2668 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2669 * misc.c (message,error,fatal): Ditto.
2670 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2671 * config.h.W32.template: Ditto.
2672 * config.h-vms.template: Ditto.
2673 * config.ami.template: Ditto.
2675 2004-03-04 Paul D. Smith <psmith@gnu.org>
2677 * README.template: Add a note about broken /bin/sh on SunOS
2678 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2680 * misc.c (message, error, fatal): Don't use "..." if we're using
2681 varargs. ansi2knr should handle this but it doesn't work: it
2682 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2683 done. On many systems (SunOS for example) va_dcl is a #define.
2684 So, force the use of the non-"..." version on pre-ANSI compilers.
2686 * maintMakefile (sign-dist): Create some rules to help automate
2687 the new GNU ftp upload method.
2689 2004-02-24 Paul D. Smith <psmith@gnu.org>
2691 * config.h.W32.template: Add HAVE_STDARG_H
2692 * config.h-vms.template: Ditto.
2693 * config.ami.template: Ditto.
2695 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2697 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2698 * build_w32.bat: Remove extra "+".
2700 2004-02-23 Paul D. Smith <psmith@gnu.org>
2702 * make.h: Create an UNUSED macro to mark unused parameters.
2703 * (many): Clean up warnings by applying UNUSED, fixing
2704 signed/unsigned incompatibilities, etc.
2706 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2708 * filedef.h: Name the command_state enumeration.
2709 * file.c (set_command_state): Use the enumeration in the function
2712 * configure.in: Explicitly set SET_MAKE to empty, to disable
2713 MAKE=make even when no make already exists. Fix bug #3823.
2715 2004-02-22 Paul D. Smith <psmith@gnu.org>
2717 * maintMakefile: Perl script to clean up all non-CVS files. Use
2718 it on all the subdirectories for the cvs-clean target.
2720 * main.c (decode_switches): Require non-empty strings for all our
2721 string command-line options. Fixes Debian bug # 164165.
2723 * configure.in: Check for stdarg.h and varargs.h.
2724 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2725 for printing messages.
2726 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2731 A number of patches for OS/2 support from Andreas Buening
2732 <andreas.buening@nexgo.de>:
2734 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2735 disable the SIGCHLD handler.
2736 (reap_children) [OS/2]: Remove special handling of job_rfd.
2737 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2738 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2739 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2740 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2741 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2744 2004-02-21 Paul D. Smith <psmith@gnu.org>
2746 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2747 <mail@kristov.de> reports that if process_begin() fails we don't
2748 handle the error condition correctly in all cases.
2749 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2750 to have a newline on the message.
2752 * job.c (construct_command_argv_internal): Add "test" to UNIX
2753 sh_cmds[]. Fixes Savannah bug # 7606.
2755 2004-02-04 Paul D. Smith <psmith@gnu.org>
2757 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2758 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2759 Hartmut Becker <Hartmut.Becker@hp.com>.
2761 2004-01-21 Paul D. Smith <psmith@gnu.org>
2763 * job.c (load_too_high): Implement an algorithm to control the
2764 "thundering herd" problem when using -l to control job creation
2765 via the load average. The system only recomputes the load once a
2766 second but we can start many jobs in a second. To solve this we
2767 keep track of the number of jobs started in the last second and
2768 apply a weight to try to guess what a correct load would be.
2769 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2770 Also fixes bug #4693.
2771 (reap_children): Decrease the job count for this second.
2772 (start_job_command): Increase the job count for this second.
2774 * read.c (conditional_line): Expand the text after ifn?def before
2775 checking to see if it's a single word. Fixes bug #7257.
2777 2004-01-09 Paul D. Smith <psmith@gnu.org>
2779 * file.c (print_file): Recurse to print all targets in
2780 double-colon rules. Fixes bug #4518, reported (with patch) by
2781 Andrew Chatham <chatham@google.com>.
2783 2004-01-07 Paul D. Smith <psmith@gnu.org>
2785 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2786 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2787 AC_FUNC_SETVBUF_REVERSED.
2789 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2790 (MAKE Variable): Fix Savannah bug #4898.
2792 * job.c (construct_command_argv_internal): Add "!" to the list of
2793 shell escape chars. POSIX sh allows it to appear before a
2794 command, to negate the exit code. Fixes bug #6404.
2796 * implicit.c (pattern_search): When matching an implicit rule,
2797 remember which dependencies have the ignore_mtime flag set.
2798 Original fix provided in Savannah patch #2349, by Benoit
2799 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2801 2003-11-22 Paul D. Smith <psmith@gnu.org>
2803 * README.W32.template (Outputs): Clarification on -j with
2804 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2807 2003-11-02 Paul D. Smith <psmith@gnu.org>
2809 * function.c (func_if): Strip all the trailing whitespace from the
2810 condition, then don't expand it. Fixed bug # 5798.
2812 * expand.c (recursively_expand_for_file): If we're expanding a
2813 variable with no file context, then use the variable's context.
2816 2003-10-21 Paul D. Smith <psmith@gnu.org>
2818 * main.c (log_working_directory): Add newlines to printf()s.
2820 * README.cvs: Add a note to ignore warnings during autoreconf.
2822 * maintMakefile (po_repo): Set a new URL for PO file updates.
2823 (get-config/config.guess get-config/config.sub): Get these files
2824 from the Savannah config project instead of ftp.gnu.org.
2826 2003-10-05 Paul Eggert <eggert@twinsun.com>
2828 * main.c (main): Avoid potential subscript error if environ has
2831 2003-08-22 Paul D. Smith <psmith@gnu.org>
2833 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2834 systems which don't yet implement the C89 standard :-/.
2836 2003-07-18 Paul D. Smith <psmith@gnu.org>
2838 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2839 [WINDOWS32]: Initialize hash.
2841 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2843 * dir.c (read_dirstream): Provide a workaround for broken versions of
2844 the MinGW dirent structure.
2846 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2848 * w32/include/dirent.h: Add __MINGW32__ filter.
2850 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2852 * make.h: Add global declaration of *make_host.
2853 * main.c (print_usage): Remove local declaration of *make_host.
2854 (print_version): Display "This program built for ..." after Copyright
2857 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2859 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2860 execution of "makeinfo --html make.texi".
2862 2003-04-30 Paul D. Smith <psmith@gnu.org>
2864 * build.template: Make some changes to maybe allow this script to
2865 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2867 * README.OS2.template: New file for OS/2 support. Original
2868 contributed by Andreas Buening.
2869 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2872 2003-04-19 Paul D. Smith <psmith@gnu.org>
2874 Fix bug #1405: allow a target to match multiple pattern-specific
2877 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2878 variable.c, where they've always belonged.
2879 * rule.h: Move the prototypes and struct pattern_var as well.
2880 * variable.c (initialize_file_variables): Invoke
2881 lookup_pattern_var() in a loop, until no more matches are found.
2882 If a match is found, create a new variable set for the target's
2883 pattern variables. Then merge the contents of each matching
2884 pattern variable set into the target's pattern variable set.
2885 (lookup_pattern_var): Change this function to be usable
2886 in a loop. It takes a starting position: if NULL, start at the
2887 beginning; if non-NULL, start with the pattern variable after that
2888 position, and return the next matching pattern.
2889 (create_pattern_var): Create a unique instance of
2890 pattern-specific variables for every definition in the makefile.
2891 Don't combine the same pattern together. This allows us to
2892 process the variable handling properly even when the same pattern
2893 is used multiple times.
2894 (parse_variable_definition): New function: break out the parsing
2895 of a variable definition line from try_variable_definition.
2896 (try_variable_definition): Call parse_variable_definition to
2898 (print_variable_data_base): Print out pattern-specific variables.
2899 * variable.h (struct variable): Remember when a variable is
2900 conditional. Also remember its flavor.
2901 (struct pattern_var): Instead of keeping a variable set, we just
2902 keep a single variable for each pattern.
2903 * read.c (record_target_var): Each pattern variable contains only a
2904 single variable, not a set, so create it properly.
2905 * doc/make.texi (Pattern-specific): Document the new behavior.
2907 2003-04-17 Paul D. Smith <psmith@gnu.org>
2909 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2910 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2911 file/directory naming rules for VMS so I can't tell whether this
2914 2003-04-09 Paul D. Smith <psmith@gnu.org>
2916 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2917 DOS-style pathnames: backslash separators and drive specifiers.
2919 2003-03-28 Paul D. Smith <psmith@gnu.org>
2921 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2922 the intermediate flag on all targets. Fixes bug #2515.
2924 2003-03-24 Paul D. Smith <psmith@gnu.org>
2926 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2927 Upgrade to autoconf 2.57 and automake 1.7.3.
2929 * job.c: More OS/2 changes from Andreas Buening.
2931 * file.c (print_file): Fix variable initialization.
2934 * remake.c (notice_finished_file):
2936 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2937 some calls (like readdir()) return NULL in valid situations
2938 without resetting errno. Fixes bug #2846.
2940 2003-02-25 Paul D. Smith <psmith@gnu.org>
2942 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2944 * job.c (_is_unixy_shell) [OS/2]: New function.
2945 Set default shell to /bin/sh.
2946 (reap_children): Close the job_rfd pipe here since we don't use a
2948 (set_child_handler_action_flags): define this to empty on OS/2.
2949 (start_job_command): Close the jobserver pipe and use
2950 child_execute_job() instead of fork/exec.
2951 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2952 rather than exec'ing, then reconfigure stdin/stdout.
2953 (exec_command): Rewrite to use spawn instead of exec. Return the
2956 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2957 in DOS. Handle the TEMP environment variable as in DOS. Don't
2958 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2959 use -j in DOS mode. Use child_execute_job() instead of
2962 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2965 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2966 prototypes that return values.
2968 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2970 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2971 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2973 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2976 2003-02-24 Paul D. Smith <psmith@gnu.org>
2978 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2979 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2980 (child_execute_job) [VMS]: Handle error status properly.
2981 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2983 * function.c (func_shell): Use EINTRLOOP() while reading from the
2984 subshell pipe (Fixes bug #2502).
2985 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2987 * main.c (main): Ditto.
2989 2003-01-30 Paul D. Smith <psmith@gnu.org>
2991 * read.c (eval): eval() was not fully reentrant, because the
2992 collapsed buffer was static. Change it to be an automatic
2993 variable so that eval() can be invoked recursively.
2995 (eval): Apply patch # 1022: fix memory reference error on long
2996 target-specific variable lines.
2997 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2999 * function.c (check_numeric): Combine the is_numeric() function
3000 into this function, since it's only called from one place.
3001 Constify this function. Have it print the incorrect string in the
3002 error message. Fixes bug #2407.
3003 (strip_whitespace): Constify.
3004 (func_if): Constify.
3005 * expand.c (expand_argument): Constify.
3007 2003-01-29 Paul D. Smith <psmith@gnu.org>
3009 Fix bug # 2169, also reported by other people on various systems.
3011 * make.h: Some systems, such as Solaris and PTX, do not fully
3012 implement POSIX-compliant SA_RESTART functionality; important
3013 system calls like stat() and readdir() can still fail with EINTR
3014 even if SA_RESTART has been set on the signal handler. So,
3015 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3016 EINTR for system calls which return -1 or 0 (NULL), respectively,
3018 Also, remove the old atomic_stat()/atomic_readdir() and
3019 HAVE_BROKEN_RESTART handling.
3021 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3023 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3024 * remake.c (touch_file): Ditto.
3026 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3027 * read.c (construct_include_path): Ditto.
3028 * remake.c (name_mtime): Ditto.
3029 * vpath.c (selective_vpath_search): Ditto.
3030 * dir.c (find_directory): Ditto.
3031 (local_stat): Ditto.
3032 (find_directory): Use ENULLLOOP() to wrap opendir().
3033 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3035 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3036 atomic_readdir() handling.
3038 2003-01-22 Paul D. Smith <psmith@gnu.org>
3040 * function.c (func_call): Fix Bug #1744. If we're inside a
3041 recursive invocation of $(call ...), mask any of the outer
3042 invocation's arguments that aren't used by this one, so that this
3043 invocation doesn't "inherit" them accidentally.
3045 2002-12-05 Paul D. Smith <psmith@gnu.org>
3047 * function.c (subst_expand): Valery Khamenia reported a
3048 pathological performance hit when doing substitutions on very
3049 large values with lots of words: turns out we were invoking
3050 strlen() a ridiculous number of times. Instead of having each
3051 call to sindex() call strlen() again, keep track of how much of
3052 the text we've seen and pass the length to sindex().
3054 2002-11-19 Paul D. Smith <psmith@gnu.org>
3056 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3059 2002-11-16 Paul D. Smith <psmith@gnu.org>
3061 * NMakefile.template (OBJS): Add hash.c object file.
3062 * SMakefile.template (srcs): Ditto.
3063 * Makefile.ami (objs): Ditto.
3064 * build_w32.bat: Ditto.
3066 * Makefile.DOS.template: Remove extra dependencies.
3068 2002-10-25 Paul D. Smith <psmith@gnu.org>
3070 * expand.c (install_variable_buffer): New function. Install a new
3071 variable_buffer context and return the previous one.
3072 (restore_variable_buffer): New function. Free the current
3073 variable_buffer context and put a previously saved one back.
3074 * variable.h: Prototypes for {install,restore}_variable_buffer.
3075 * function.c (func_eval): Push a new variable_buffer context
3076 before we eval, then restore the old one when we're done.
3079 * read.c (install_conditionals): New function. Install a new
3080 conditional context and return the previous one.
3081 (restore_conditionals): New function. Free the current
3082 conditional context and put a previously saved one back.
3083 (eval): Use the {install,restore}_conditionals for "include"
3085 (eval_buffer): Use {install,restore}_conditionals to preserve the
3086 present conditional state before we evaluate the buffer.
3089 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3091 (Recursion): Add a variable index entry for CURDIR.
3093 * README.cvs: Update to appropriate versions.
3094 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3095 don't need to copy loadavg.c: automake is smart enough to create
3096 it for me. Still have a bug in automake related to ansi2knr tho.
3098 2002-10-14 Paul D. Smith <psmith@gnu.org>
3100 * remake.c (notice_finished_file): Only touch targets if they have
3101 at least one command (as per POSIX). Resolve Bug #1418.
3103 * *.c: Convert to using ANSI C-style function definitions.
3104 * Makefile.am: Enable the ansi2knr feature of automake.
3105 * configure.in: ditto.
3107 2002-10-13 Paul D. Smith <psmith@gnu.org>
3109 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3110 for automatic variable values like $^, etc. In the case of very
3111 large lists of prerequisites this causes problems. Instead reuse
3112 a static buffer (resizeable) for each variable.
3114 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3115 target-specific variable definitions. Check for it and set an
3117 (record_target_var): Set the export field to v_export if the
3118 "exported" flag is set.
3119 * doc/make.texi (Target-specific): Document the ability to use
3122 * doc/make.texi: Change the name of the section on automatic
3123 variables from "Automatic" to "Automatic Variables". Added text
3124 clarifying the scope of automatic variables.
3126 2002-10-04 Paul D. Smith <psmith@gnu.org>
3128 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3130 (record_files): Ditto.
3132 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3133 the search for the '=' to only within the enclosing parens.
3135 2002-10-03 Paul D. Smith <psmith@gnu.org>
3137 Version 3.80 released.
3139 * dir.c: Change hash functions to use K&R function definition style.
3140 * function.c: Ditto.
3142 * variable.c: Ditto.
3144 Update to automake 1.7.
3146 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3147 (pdf): Remove this target as automake now provides one.
3149 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3151 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3153 * makefile.com: Updates for GNU make 3.80.
3154 * makefile.vms: Ditto.
3156 2002-09-23 Paul D. Smith <psmith@gnu.org>
3158 * read.c (enum make_word_type): Remove w_comment.
3159 (get_next_mword): Don't treat comment characters as special; where
3160 this function is used we will never see a comment (it's stripped
3161 before we get here) and treating comments specially means that
3162 targets like "foo\#bar" aren't handled properly.
3164 2002-09-18 Paul D. Smith <psmith@gnu.org>
3166 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3168 * read.c (eval): Expansion of arguments to export/unexport was
3169 ignoring all arguments after the first one. Change the algorithm
3170 to expand the whole line once, then parse the results.
3172 2002-09-17 Paul D. Smith <psmith@gnu.org>
3174 Fix Bug #940 (plus another bug I found while looking at this):
3176 * read.c (record_target_var): enter_file() will add a new entry if
3177 it's a double-colon target: we don't want to do that in this
3178 situation. Invoke lookup_file() and only enter_file() if it does
3179 not already exist. If the file we get back is a double-colon then
3180 add this variable to the "root" double-colon target.
3182 * variable.c (initialize_file_variables): If this file is a
3183 double-colon target but is not the "root" target, then initialize
3184 the root and make the root's variable list the parent of our
3187 2002-09-13 Paul D. Smith <psmith@gnu.org>
3189 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3191 * hash.c (round_up_2): Get rid of a warning.
3193 2002-09-12 Paul D. Smith <psmith@gnu.org>
3195 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3196 so it doesn't complain about getloadavg.c.
3198 * commands.c (set_file_variables): Make sure we always alloca() at
3199 least 1 character for the value of $? (for '\0').
3201 2002-09-11 Paul D. Smith <psmith@gnu.org>
3203 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3204 macro to use RESULT instead of the incorrect _RESULT_.
3206 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3207 and atomic_readdir(). We need to #include dirent.h to get this to
3209 * misc.c (atomic_readdir): Fix typos.
3211 2002-09-10 Paul D. Smith <psmith@gnu.org>
3213 * read.c (eval): Expand variable lists given to export and
3214 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3215 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3217 * doc/make.texi (Variables/Recursion): Document this.
3218 (Conditional Syntax): And here.
3220 2002-09-09 Paul D. Smith <psmith@gnu.org>
3222 * configure.in: Check for memmove().
3224 2002-09-07 Paul D. Smith <psmith@gnu.org>
3226 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3227 Michael Sterrett <msterret@coat.com> reports that while it has
3228 SA_RESTART, it does not work properly.
3230 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3231 that invokes stat() and loops to do it again if it returns EINTR.
3232 (atomic_readdir): Ditto, with readdir().
3234 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3235 and readdir() to atomic_stat() and atomic_readdir().
3237 2002-09-04 Paul D. Smith <psmith@gnu.org>
3239 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3240 reports that GNU make sometimes doesn't recognize that targets can
3241 be made, when directories can be created as prerequisites. He
3242 reports that changing the order of predicates in the DEP->changed
3243 flag test so that lookup_file() is always performed, solves this
3246 2002-08-08 Paul D. Smith <psmith@gnu.org>
3248 * configure.in: Require a newer version of gettext.
3250 * misc.c (perror_with_name): Translate the format string (for
3251 right-to-left language support).
3252 (pfatal_with_name): Ditto.
3254 * main.c: Create a static array of strings to store the usage
3255 text. This is done to facilitate translations.
3256 (struct command_switch): Remove argdesc and description fields.
3257 (switches): Remove values for obsolete fields.
3258 (print_usage): Print each element of the usage array.
3260 * hash.c: Change function definitions to be K&R style.
3262 2002-08-02 Paul D. Smith <psmith@gnu.org>
3264 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3265 this one because it's too hard to get right. We'll look at it for
3267 * main.c (main): Don't create the .TARGETS variable.
3268 * variable.c (handle_special_var): Don't handle .TARGETS.
3270 2002-08-01 Paul D. Smith <psmith@gnu.org>
3272 * main.c (switches): Add a new option, -B (--always-make). If
3273 specified, make will rebuild all targets that it encounters even
3274 if they don't appear to be out of date.
3275 (always_make_flag): New flag.
3276 * make.h: Extern always_make_flag.
3277 * remake.c (update_file_1): Check always_make_flag; if it's set we
3278 will always rebuild any target we can, even if none of its
3279 prerequisites are newer.
3282 * doc/make.texi (Shell Function): Make it clear that make
3283 variables marked as "export" are not passed to instances of the
3286 Add new introspection variable .VARIABLES and .TARGETS.
3288 * variable.c (handle_special_var): New function. If the variable
3289 reference passed in is "special" (.VARIABLES or .TARGETS),
3290 calculate the new value if necessary. .VARIABLES is handled here:
3291 walk through the hash of defined variables and construct a value
3292 which is a list of the names. .TARGETS is handled by
3293 build_target_list().
3294 (lookup_variable): Invoke handle_special_var().
3295 * file.c (build_target_list): Walk through the hask of known files
3296 and construct a list of the names of all the ones marked as
3298 * main.c (main): Initialize them to empty (and as simple variables).
3299 * doc/make.texi (Special Variables): Document them.
3300 * NEWS: Mention them.
3302 * variable.h (struct variable): Add a new flag "exportable" which
3303 is true if the variable name is valid for export.
3304 * variable.c (define_variable_in_set): Set "exportable" when a new
3305 variable is defined.
3306 (target_environment): Use the "exportable" flag instead of
3307 re-checking the name here... an efficiency improvement.
3309 2002-07-31 Paul D. Smith <psmith@gnu.org>
3311 * config.h-vms.template: Updates to build on VMS. Thanks to
3312 Brian_Benning@aksteel.com for helping verify the build.
3313 * makefile.com: Build the new hash.c file.
3314 * hash.h: Use strcpmi(), not stricmp(), in the
3315 HAVE_CASE_INSENSITIVE_FS case.
3317 2002-07-30 Paul D. Smith <psmith@gnu.org>
3319 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3320 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3321 Reported by <Brian_Benning@aksteel.com>.
3323 2002-07-10 Paul D. Smith <psmith@gnu.org>
3325 * variable.c (pop_variable_scope): Remove variable made unused by
3326 new hash infrastructure.
3327 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3328 comparisons as well as name comparisons.
3329 * variable.h: Add a prototype for new hash_init_function_table().
3330 * file.c (lookup_file): Remove variables made unused by new hash
3332 * dir.c (directory_contents_hash_2): Missing return of hash value.
3333 (dir_contents_file_exists_p): Remove variables made unused by new
3334 hash infrastructure.
3337 Installed Greg McGary's integration of the hash functions from the
3338 GNU id-utils package:
3340 2002-07-10 Greg McGary <greg@mcgary.org>
3342 * scripts/functions/filter-out: Add literals to to the
3343 pattern space in order to add complexity, and trigger
3344 use of an internal hash table. Fix documentation strings.
3345 * scripts/targets/INTERMEDIATE: Reverse order of files
3346 passed to expected `rm' command.
3348 2002-07-10 Greg McGary <greg@mcgary.org>

3440 2002-07-10 Paul D. Smith <psmith@gnu.org>
3442 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3443 prerequisite list. A real SysV make will expand the entire
3444 prerequisites list _twice_: we don't do that as it's a big
3445 backward-compatibility problem. We only replace those specific
3448 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3449 references left in the list of prerequisites. Check for .POSIX as
3450 we record targets, so we can disable non-POSIX behavior while
3451 reading makefiles as well as running them.
3452 (eval): Check the prerequisite list to see if we have anything
3453 that looks like a SysV prerequisite variable reference.
3455 2002-07-09 Paul D. Smith <psmith@gnu.org>
3457 * doc/make.texi (Prerequisite Types): Add a new section describing
3458 order-only prerequisites.
3460 * read.c (uniquize_deps): If we have the same file as both a
3461 normal and order-only prereq, get rid of the order-only prereq,
3462 since the normal one supersedes it.
3464 2002-07-08 Paul D. Smith <psmith@gnu.org>
3466 * AUTHORS: Added Greg McGary to the AUTHORS file.
3467 * NEWS: Blurbed order-only prerequisites.
3468 * file.c (print_file): Show order-only deps properly when printing
3471 * maintMakefile: Add "update" targets for wget'ing the latest
3472 versions of various external files. Taken from Makefile.maint in
3475 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3476 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3478 2002-07-07 Paul D. Smith <psmith@gnu.org>
3480 * po/*.po: Remove. We'll use wget to retrieve them at release
3483 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3484 rather than a shell you get an exception. Make sure we look up
3485 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3487 * remake.c (notice_finished_file): Fix handling of -t flag.
3488 Patch provided by Henning Makholm <henning@makholm.net>.
3490 * implicit.c (pattern_search): Some systems apparently run short
3491 of stack space, and using alloca() in this function caused an
3492 overrun. I modified it to use xmalloc() on the two variables
3493 which seemed like they might get large. Fixes Bug #476.
3495 * main.c (print_version): Update copyright notice to conform with
3497 (print_usage): Update help output.
3499 * function.c (func_eval): Create a new make function, $(eval
3500 ...). Expand the arguments, put them into a buffer, then invoke
3501 eval_buffer() on the resulting string.
3502 (func_quote): Create a new function, $(quote VARNAME). Inserts
3503 the value of the variable VARNAME without expanding it any
3506 * read.c (struct ebuffer): Change the linebuffer structure to an
3507 "eval buffer", which can be either a file or a buffer.
3508 (eval_makefile): Move the code in the old read_makefile() which
3509 located a makefile into here: create a struct ebuffer with that
3510 information. Have it invoke the new function eval() with that
3512 (eval_buffer): Create a new function that creates a struct ebuffer
3513 that holds a string buffer instead of a file. Have it invoke
3514 eval() with that ebuffer.
3515 (eval): New function that contains the guts of the old
3516 read_makefile() function: this function parses makefiles. Obtains
3517 data to parse from the provided ebuffer. Some modifications to
3518 make the flow of the function cleaner and clearer. Still could
3519 use some work here...
3520 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3521 contents of the define/endef variable from the ebuffer.
3522 (readstring): Read the next line from a string-style ebuffer.
3523 (readline): Read the next line from an ebuffer. If it's a string
3524 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3527 * dep.h (eval_buffer): Prototype eval_buffer();
3529 * variable.c (do_variable_definition): Make sure that all
3530 non-target-specific variables are registered in the global set.
3531 If we're invoked from an $(eval ...) we might be inside a $(call
3532 ...) or other function which has pushed a variable scope; we still
3533 want to define our variables from evaluated makefile code in the
3536 2002-07-03 Greg McGary <greg@mcgary.org>
3538 * dep.h (struct dep) [ignore_mtime]: New member.
3539 [changed]: convert to a bitfield.
3540 * implicit.c (pattern_search): Zero ignore_mtime.
3541 * main.c (main, handle_non_switch_argument): Likewise.
3542 * rule.c (convert_suffix_rule): Likewise.
3543 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3544 (read_makefile): Parse '|' in prerequisite list.
3545 (uniquize_deps): Consider ignore_mtime when comparing deps.
3546 * remake.c (update_file_1, check_dep): Don't force remake for
3547 dependencies that have d->ignore_mtime.
3548 * commands.c (FILE_LIST_SEPARATOR): New constant.
3549 (set_file_variables): Don't include a
3550 prerequisite in $+, $^ or $? if d->ignore_mtime.
3553 2002-06-18 Paul D. Smith <psmith@gnu.org>
3555 * make.texinfo: Updates for next revision. New date/rev/etc.
3556 Recreate all Info menus. Change license on the manual to the GNU
3557 Free Documentation License. A number of typos.
3558 (Variables Simplify): Don't use "-" before it's defined.
3559 (Automatic Prerequisites): Rewrite the target example to work
3560 properly if the compile fails. Remove incorrect comments about
3561 how "set -e" behaves.
3562 (Text Functions): Move the "word", "wordlist", "words", and
3563 "firstword" functions here, from "File Name Functions".
3564 * make-stds.texi: Update from latest GNU version.
3565 * fdl.texi: (created) Import the latest GNU version.
3567 2002-06-06 Paul D. Smith <psmith@gnu.org>
3569 * variable.c (do_variable_definition): New function: extract the
3570 part of try_variable_definition() that actually sets the value
3571 into a separate function.
3572 (try_variable_definition): Call do_variable_definition() after
3573 parsing the variable definition string.
3574 (define_variable_in_set): Make the name argument const.
3576 * variable.h (enum variable_flavor): Make public.
3577 (do_variable_definition): Create prototype.
3579 * read.c (read_all_makefiles): Create a new built-in variable,
3581 (read_makefile): Add each makefile read in to this variable value.
3583 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3585 * Makefile.DOS.template: Tweak according to changes in the
3586 distribution. Add back the dependencies of *.o files.
3588 * configh.dos.template: Synchronize with config.h.in.
3590 2002-05-09 Paul D. Smith <psmith@gnu.org>
3592 * file.c (file_timestamp_now): Use K&R function declaration.
3594 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3595 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3596 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3597 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3598 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3599 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3600 nlist.n_name is a pointer rather than an array.
3602 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3603 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3604 * configure.in: Use it instead of the old version.
3606 * main.c (main): Prefer setvbuf() to setlinebuf().
3608 2002-05-08 Paul D. Smith <psmith@gnu.org>
3610 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3611 (loadavg_LDADD): Ditto.
3613 2002-04-29 Paul D. Smith <psmith@gnu.org>
3615 * expand.c (recursively_expand_for_file): Rename
3616 recursively_expand() to recursively_expand_for_file() and provide
3617 an extra argument, struct file. If the argument is provided, set
3618 the variable scope to that of the file before expanding.
3619 * variable.h (recursively_expand): Make this a macro that invokes
3620 recursively_expand_for_file() with a NULL file pointer.
3621 * variable.c (target_environment): Call the renamed function and
3622 provide the current file context.
3623 Fixes Debian bug #144306.
3625 2002-04-28 Paul D. Smith <psmith@gnu.org>
3627 Allow $(call ...) user-defined variables to be self-referencing
3628 without throwing an error. Allows implementation of transitive
3629 closures, among other possibly useful things.
3630 Requested by: Philip Guenther <guenther@sendmail.com>
3632 * variable.h (struct variable): Add a new field: exp_count, and
3633 new macros to hold its size and maximum value.
3634 (warn_undefined): Make this a macro.
3635 * variable.c (define_variable_in_set): Initialize it.
3636 * expand.c (recursively_expand): If we detect recursive expansion
3637 of a variable, check the exp_count field. If it's greater than 0
3638 allow the recursion and decrement the count.
3639 (warn_undefined): Remove this (now a macro in variable.h).
3640 * function.c (func_call): Before we expand the user-defined
3641 function, modify its exp_count field to contain the maximum
3642 number of recursive calls we'll allow. After the call, reset it
3645 2002-04-21 Paul D. Smith <psmith@gnu.org>
3647 Modified to use latest autoconf (2.53), automake (1.6.1), and
3648 gettext (0.11.1). We're using gettext's new "external" support,
3649 to avoid including libintl source with GNU make.
3651 * README.cvs: New file. Explain how to build GNU make from CVS.
3653 * configure.in: Modify checking for the system glob library.
3654 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3655 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3656 etc. will manage it correctly). Set an automake conditional
3657 USE_LOCAL_GLOB to decide whether to compile the glob library.
3659 * getloadavg.c (main): Include make.h in the "TEST" program to
3662 * Makefile.am: Remove special rules for loadavg. Replace them
3663 with Automake capabilities for building extra programs.
3665 * signame.c: This file does nothing if the system provide
3666 strsignal(). If not, it implements strsignal(). If the system
3667 doesn't define sys_siglist, then we make our own; otherwise we use
3669 * signame.h: Removed.
3671 * main.c (main): No need to invoke signame_init(). Update copyright.
3673 * ABOUT-NLS: Removed.
3674 * gettext.c: Removed.
3675 * gettext.h: Get a simplified copy from the gettext package.
3677 * i18n/*.po: Moved to po/.
3680 * config/*: Created. Contains package configuration helper files.
3681 * config.guess, config.sub: Moved to config directory.
3683 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3684 Rework to use new-style autoconf features. Use the "external"
3685 mode for gettext. Make the build.sh config file conditional on
3686 whether build.sh.in exists, to avoid autoconf errors.
3687 * acinclude.m4: Removed almost all macros as being obsolete.
3688 Rewrote remaining macros to use AC_DEFINE.
3689 * acconfig.h: Removed.
3691 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3692 conditional to handle customs support. Remove special handling
3695 2002-04-20 Paul D. Smith <psmith@gnu.org>
3697 * function.c (func_call): Don't mark the argument variables $1,
3698 etc. as recursive. They've already been fully expanded so
3699 there's no need to do it again, and doing so strips escaped $'s.
3700 Reported by Sebastian Glita <glseba@yahoo.com>.
3702 * remake.c (notice_finished_file): Walk through double-colon
3703 entries via the prev field, not the next field!
3704 Reported by Greg McGary <greg@mcgary.org>.
3706 * main.c (main): If the user specifies -q and asks for a specific
3707 target which is a makefile, we got an assert. In that case it
3708 turns out we should continue normally instead.
3710 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3712 * i18n/he.po: Installed a new translation.
3714 2002-01-07 Paul D. Smith <psmith@gnu.org>
3716 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3718 2001-12-04 Paul D. Smith <psmith@gnu.org>
3720 * i18n/ja.po: Installed an updated translation.
3722 2001-09-06 Paul Eggert <eggert@twinsun.com>
3724 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3725 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3727 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3729 (main): Get rid of any avoidable limit on stack size.
3731 2001-09-04 Paul D. Smith <psmith@gnu.org>
3733 * i18n/da.po: Installed an updated translation.
3735 2001-08-03 Paul D. Smith <psmith@gnu.org>
3737 * i18n/fr.po: Installed an updated translation.
3738 Resolves Debian bug #106720.
3740 2001-06-13 Paul D. Smith <psmith@gnu.org>
3742 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3745 2001-06-11 Paul D. Smith <psmith@gnu.org>
3747 * i18n/ko.po: Installed a new translation.
3749 2001-05-06 Paul D. Smith <psmith@gnu.org>
3751 Modify the EINTR handling.
3753 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3754 the way in which we manage the file descriptor/signal handler race
3755 trap to be more efficient.
3757 2001-05-06 Paul Eggert <eggert@twinsun.com>
3759 Restart almost all system calls that are interrupted, instead
3760 of worrying about EINTR. The lone exception is the read() for
3763 * configure.in (HAVE_SA_RESTART): New macro.
3764 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3765 * main.c (main): Use SA_RESTART instead of the old,
3766 nonstandard SA_INTERRUPT.
3768 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3769 * main.c (bsd_signal): New function or macro,
3770 if the implementation doesn't supply it.
3771 (The bsd_signal function will be in POSIX 1003.1-200x.)
3772 (HANDLESIG): Remove.
3773 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3775 * make.h (EINTR_SET): Remove.
3776 (SA_RESTART): New macro.
3778 * arscan.c (ar_member_touch): Don't worry about EINTR.
3779 * function.c (func_shell): Likewise.
3780 * job.c (reap_children, free_child, new_job): Likewise.
3781 * main.c (main): Likewise.
3782 * remake.c (touch_file, name_mtime): Likewise.
3784 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3785 if fstat failed with errno!=EINTR, the error was ignored.
3787 * job.c (set_child_handler_action_flags): New function.
3788 (new_job): Use it to temporarily clear the SIGCHLD action flags
3789 while reading the token.
3791 2001-05-02 Paul D. Smith <psmith@gnu.org>
3793 * job.c (start_job_command): Don't add define/endef per-line flags
3794 to the top-level flags setting.
3796 2001-04-03 Paul D. Smith <psmith@gnu.org>
3798 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3799 bit on error, so check for odd return values, not non-0 return
3801 (VMS_get_member_info): Calculate the timezone differences correctly.
3802 Reported by John Fowler <jfowler@nyx.net>.
3805 2001-03-14 Paul D. Smith <psmith@gnu.org>
3807 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3808 value before invoking define_variable().
3809 Reported by John Fowler <jfowler@nyx.net>.
3811 2001-02-07 Paul D. Smith <psmith@gnu.org>
3813 * read.c (record_target_var): If we reset the variable due to a
3814 command-line variable setting overriding it, turn off the "append"
3817 2001-01-17 Paul D. Smith <psmith@gnu.org>
3819 * variable.c (lookup_variable) [VMS]: When getting values from the
3820 environment, allocate enough space for the _value_ plus escapes,
3821 not enough space for the name plus escapes :-/.
3822 Reported by John Fowler <jfowler@nyx.net>.
3824 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3825 warnings that make generates, so it doesn't look like an error.
3826 Reported by Karl Berry <karl@gnu.org>.
3829 Fix for PR/2020: Rework appended target-specific variables. I'm
3830 fairly confident this algorithm is finally correct.
3832 * expand.c (allocated_variable_append): Rewrite. Instead of
3833 expanding each appended variable then adding all the expanded
3834 strings together, we append all the unexpanded values going up
3835 through the variable set contexts, then expand the final result.
3836 This behaves just like non-target-specific appended variable
3837 values, while the old way didn't in various corner cases.
3838 (variable_append): New function: recursively append the unexpanded
3839 value of a variable, walking from the outermost variable scope to
3841 * variable.c (lookup_variable): Remove the code that looked up the
3842 variable set list if the found variable was "append". We don't
3844 (lookup_variable_in_set): Make this non-static so we can use it
3846 (try_variable_definition): Use lookup_variable_in_set() rather
3847 than faking out current_variable_set_list by hand (cleanup).
3848 * variable.h: Add a prototype for the now non-static
3849 lookup_variable_in_set().
3851 2000-11-17 Paul D. Smith <psmith@gnu.org>
3853 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3854 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3855 before throwing a fit.
3857 2000-11-17 Paul D. Smith <psmith@gnu.org>
3859 * read.c (readline): CRLF calculations had a hole, if you hit the
3860 buffer grow scenario just right. Reworked the algorithm to avoid
3861 the need for len or lastlen at all. Problem description with
3862 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3864 2000-10-24 Paul D. Smith <psmith@gnu.org>
3866 * gettext.c (SWAP): Declare this with the prototype, otherwise
3867 some systems don't work (non-32-bit? Reported for Cray T3E).
3868 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3870 2000-10-05 Paul D. Smith <psmith@gnu.org>
3872 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3873 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3875 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3877 2000-09-22 Paul D. Smith <psmith@gnu.org>
3879 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3880 parts of the real gettext.h here, and we expect to really include
3881 the real gettext.h later. If we keep this #define, it's ignored.
3883 2000-09-21 Paul D. Smith <psmith@gnu.org>
3885 * main.c (log_working_directory): Rework the text to use complete
3886 sentences, to make life simpler for the translators.
3888 2000-08-29 Paul D. Smith <psmith@gnu.org>
3890 * file.c (remove_intermediates): Print a debug message before we
3891 remove intermediate files, so the user (if she uses -d) knows
3894 2000-08-21 Paul D. Smith <psmith@gnu.org>
3896 * variable.c (try_variable_definition): Change how we handle
3897 target-specific append variable defns: instead of just setting the
3898 value, expand it as an append _but_ only within the current
3899 target's context. Otherwise we lose all but the last value if the
3900 variable is appended more than once within the current target
3901 context. Fixes PR/1831.
3903 2000-08-16 Paul D. Smith <psmith@gnu.org>
3905 * function.c (func_shell): Nul-terminate the buffer before
3906 printing an exec error message (just in case it's not!).
3907 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3909 2000-07-25 Paul D. Smith <psmith@gnu.org>
3911 * job.c (construct_command_argv_internal): Add "~" to the list of
3912 sh_chars[] which disallow optimizing out the shell call.
3914 2000-07-23 Paul Eggert <eggert@twinsun.com>
3916 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3917 supersedes --disable-nsec-timestamps.
3918 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3919 * README: Remove --disable-nsec-timestamps.
3921 * filedef.h (struct file.low_resolution_time): New member.
3922 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3923 * remake.c (update_file_1):
3924 Avoid spurious rebuilds due to low resolution time stamps,
3925 generalizing the earlier code that applied only to archive members.
3926 (f_mtime): Archive members always have low resolution time stamps.
3928 * configure.in: Remove --disable-nsec-timestamps, as this has
3929 been superseded by .LOW_RESOLUTION_TIME.
3931 2000-07-23 Paul Eggert <eggert@twinsun.com>
3933 * configure.in (enable_nsec_timestamps): Renamed from
3934 make_cv_nsec_timestamps, since enable/disable options
3935 shouldn't be cached.
3937 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3938 and Paul Eggert <eggert@twinsun.com>
3940 * file.c (file_timestamp_now):
3941 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3942 so that clock_gettime is not linked unless needed.
3944 * filedef.h (FILE_TIMESTAMP_HI_RES):
3945 Remove definition; "configure" now does this.
3947 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3948 to before high resolution file timestamp check,
3949 since that check now uses uintmax_t.
3950 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3951 high resolution file timestamps.
3952 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3953 so that we don't link in clock_gettime unnecessarily.
3955 2000-07-17 Paul D. Smith <psmith@gnu.org>
3957 * i18n/ja.po: New version of the translation file.
3959 2000-07-07 Paul D. Smith <psmith@gnu.org>
3961 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3962 the offset calculation.
3963 (name_mtime): Replace EINTR test with EINTR_SET macro.
3965 2000-07-07 Paul Eggert <eggert@twinsun.com>
3969 * remake.c (update_file_1):
3970 Avoid spurious rebuilds of archive members due to their
3971 timestamp resolution being only one second.
3972 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3973 the clock's resolution being lower than file timestamps'.
3974 When warning about future timestamps, report only the discrepancy,
3975 not the absolute value of the timestamp and the current time.
3977 * file.c (file_timestamp_now): New arg RESOLUTION.
3978 * filedef.h (file_timestamp_now): Likewise.
3979 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3981 2000-07-05 Paul D. Smith <psmith@gnu.org>
3983 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3984 to listp. Fixes PR/1793.
3986 2000-06-26 Paul Eggert <eggert@twinsun.com>
3988 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3990 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3992 * remake.c (f_mtime): Remove unused var memtime.
3994 2000-06-25 Martin Buchholz <martin@xemacs.org>
3996 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3997 Ran spell-check on make.texinfo.
3999 2000-06-23 Paul D. Smith <psmith@gnu.org>
4001 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4002 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4003 * make.h: Define these macros.
4005 * Version 3.79.1 released.
4007 * configure.in: Add a new option, --disable-nsec-timestamps, to
4008 avoid using sub-second timestamps on systems that support it. It
4009 can lead to problems, e.g. if your makefile relies on "cp -p".
4010 * README.template: Document the issue with "cp -p".
4012 * config.guess, config.sub: Updated.
