211 which allows the caller to get the index of the matching directory.
213 * make.h (vpath_search): Update prototype.
215 * remake.c (library_search): Implement linker-compatible library

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

313 2009-10-03 Paul Smith <psmith@gnu.org>
315 * make.h: Include <alloca.h> even on systems where __GNUC__ is

375 double-colons have a different meaning. Savannah bug #27497.
377 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
379 * configh.dos.template: Remove unconditional definition of
380 SYS_SIGLIST_DECLARED.
381 Include <sys/version.h> because ports of GCC 4.3.0 and later no
382 longer include it, so macros like __DJGPP_MINOR__ are no longer
383 defined automatically.
385 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
386 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
387 instead of using the hardcoded ones.
388 (SUBDIRS): doc subdir added.
389 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
390 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
391 create html formated docs. texi2html may not be ported to DOS.
392 (make.info, make.dvi, make.ps, make.html): Make targets depend on
394 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
395 -I switch to look in ./ instead of ./doc.

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

401 (mostlyclean-recursive, clean-recursive, distclean-recursive)
402 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
403 (tags-recursive): Allow for more than one subdir in the build
405 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
406 targets. Enter into doc/ to produce the targets.

409 2009-09-26 Paul Smith <psmith@gnu.org>
411 * read.c (record_files): Use free_ns() to free struct nameseq.
414 * rule.c (freerule): Use free_dep_chain().
416 * read.c (record_files): Free FILENAMES chain for implicit rules.

419 * function.c (string_glob): Free NAME in the nameseq chain.
421 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
423 * implicit.c (pattern_search): Terminate early if we haven't
424 found any rules to try (performance improvement).
426 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
428 * implicit.c (pattern_search): Merge three parallel arrays,
429 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
430 of struct TRYRULE. In the old version the latter two arrays
431 had insufficient length.
433 2009-09-24 Paul Smith <psmith@gnu.org>
435 * implicit.c (pattern_search): Add back support for order-only
436 prerequisites for secondary expansion implicit rules, that were
437 accidentally dropped. If we find a "|", enable order-only mode
438 and set IGNORE_MTIME on all deps that are seen afterward.
439 (pattern_search): Fix memory leaks: for intermediate files where
440 we've already set the file variable and pattern variable sets, be
441 sure to either save or free them as appropriate.
443 2009-09-23 Paul Smith <psmith@gnu.org>
445 Rework the way secondary expansion is stored, for efficiency.
446 This changes secondary expansion so that ONLY WHEN we know we have
447 a possibility of needing secondary expansion, do we defer the
448 secondary expansion. This means more parsing the deps but we use
449 a lot less memory (due to the strcache). Also, this fixes
452 * read.c (eval): Don't parse the dep string here anymore.
453 (record_files): Take the dep argument as an unparsed string. If
454 secondary expansion is enabled AND the prereq string has a '$' in
455 it, then set NEED_2ND_EXPANSION and keep the entire string.
456 Otherwise, parse the dep string here to construct the dep list
457 with the names in the strcache.
459 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
460 duplicate the name string (others are in the strcache).
462 * implicit.c: Remove struct idep and free_idep_chain(): unused.
463 (struct patdeps): New structure to store prereq information.
464 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
465 which prerequisites need expansion, and expand only those.
467 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
468 and enter_prereqs(). split_prereqs() takes a fully-expanded string
469 and splits it into a DEP list, handling order-only prereqs.
470 (enter_prereqs): This function enters a list of DEPs into the file
471 database. If there's a stem defined, expand any pattern chars.
472 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
473 set. Use the above functions.
474 (snap_deps): Only perform second expansion on prereqs that need it,
475 as defined by the NEED_2ND_EXPANSION flag.
476 (print_prereqs): New function to print the prereqs
477 (print_file): Call print_prereqs() rather than print inline.
479 * hash.h (STRING_COMPARE): Take advantage of strcache() by
481 (STRING_N_COMPARE): Ditto.
482 (ISTRING_COMPARE): Ditto.
484 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
485 (parse_file_seq): Return void*
486 * read.c (parse_file_seq): Return void*.
487 (eval): Invoke macroized version of parse_file_seq()
488 * default.c (set_default_suffixes): Ditto.
489 * file.c (split_prereqs): Ditto.
490 * function.c (string_glob): Ditto.
491 * main.c (main): Ditto.
492 * rule.c (install_pattern_rule): Ditto.
494 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
496 2009-09-16 Paul Smith <psmith@gnu.org>
498 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
500 * dep.h: Create alloc_dep() / free_dep() macros.
502 * implicit.c (pattern_search): Take advantage of the new
503 parse_file_seq() to add the directory prefix to each prereq.
505 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
506 all. Avoid reversing chains. Support adding prefixes.
507 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
508 cached/non-cached results.
509 (eval): Remove multi_glob() & invoke new parse_file_seq().
510 * rule.c (install_pattern_rule): Ditto.
511 * main.c (main): Ditto.
512 * implicit.c (pattern_search): Ditto.
513 * function.c (string_glob): Ditto.
514 * file.c (parse_prereqs): Ditto.
515 * default.c (set_default_suffixes): Ditto.
517 * variable.c (parse_variable_definition): Don't run off the end of
518 the string if it ends in whitespace (found with valgrind).
520 * commands.c (set_file_variables): Keep space for all targets in
521 $? if -B is given (found with valgrind).
523 2009-09-15 Paul Smith <psmith@gnu.org>
525 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
526 (xcalloc): Add new function.
527 * make.h: New declarations.
529 * ar.c (ar_glob_match): New calling method for concat().
530 * main.c (main): Ditto.

535 * variable.c (target_environment): Ditto.
536 (sync_Path_environment): Ditto.
538 * ar.c (ar_glob_match): Use xcalloc().
539 * dir.c (file_impossible): Ditto.
540 * file.c (enter_file): Ditto.
541 * job.c (new_job): Ditto.
542 * read.c (parse_file_seq): Ditto.
543 * vmsfunctions.c (opendir): Ditto.
545 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)

553 sync_Path_environment.
555 2009-08-02 Paul Smith <psmith@gnu.org>
557 * remake.c (notice_finished_file): Ensure file->cmds is not null
558 before looping through them. Fixes Savannah bug #21824.
560 * doc/make.texi (Wildcard Examples): Clarify when objects is
561 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
562 (Include): Clarify the behavior of -include.
563 Fixes Savannah bug #18963.
565 2009-08-01 Paul Smith <psmith@gnu.org>
567 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
568 etc. come on the command line. Fixes Savannah bug #27093.
570 * expand.c (expand_argument): If the argument is large enough use
571 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
573 * variable.c (do_variable_definition): Avoid using alloca() to
574 hold values, which can be large. Fixes Savannah bug #23960.
576 * job.c (new_job): Use memmove() instead of strcpy() since both
577 pointers are in the same memory block. Fixes Savannah bug #27148.
578 Patch by Petr Machata.
580 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
582 * job.c (construct_command_argv_internal): Add "ulimit" and
583 "unset" to the sh_cmds for Unixy shells.
585 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
587 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
588 that set make_cv_sys_gnu_glob, so they are also correctly set
589 when the cache has been populated before.
591 2009-07-04 Eli Zaretskii <eliz@gnu.org>
593 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
594 exist, as realpath(3) does where it's supported.
596 2006-07-04 Eli Zaretskii <eliz@gnu.org>
598 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
599 (abspath): Support systems that define HAVE_DOS_PATHS (have
600 drive letters in their file names). Use IS_PATHSEP instead of a
601 literal '/' comparison. Fixes Savannah bug #26886.
603 2009-06-14 Paul Smith <psmith@gnu.org>
605 * remake.c (update_file_1): Remember the original file we marked
606 as updating, so we can clear that flag again. If we find a target
607 via vpath, FILE might change.
608 (check_dep): Ditto. Fixes Savannah bug #13529.
609 Patch by Reid Madsen <reid.madsen@tek.com>.
611 2009-06-13 Paul Smith <psmith@gnu.org>
613 * doc/make.texi (MAKEFILES Variable): Be explicit that files
614 included by MAKEFILES cannot give default goals.
615 * read.c (eval): If set_default is not set, pass the no-default-goal
616 value when we read included makefiles. Fixes Savannah bug #13401.
618 * ar.c (ar_name): Ensure that targets with empty parens aren't
619 considered archive member references: archive members must have a
620 non-empty "member" string. Fixes Savannah bug #18435.
622 * function.c (string_glob): Rely on multi_glob() to determine
623 whether files exist or not. Remove call to file_exists_p() which
624 is not always correct. Fixes Savannah bug #21231.
625 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
626 then only files that really exist will be returned.
627 * dep.h: Add new argument to multi_glob().
628 * rule.c (install_pattern_rule): Ditto.
629 * read.c (eval): Ditto.
630 * main.c (main): Ditto.
631 * implicit.c (pattern_search): Ditto.
632 * file.c (parse_prereqs): Ditto.
633 * default.c (set_default_suffixes): Ditto.
635 2009-06-09 Paul Smith <psmith@gnu.org>
637 * commands.c (set_file_variables): If always_make_flag is set,
638 always add the prereq to $?. Fixes Savannah bug #17825.
640 * remake.c (update_file_1): When rebuilding deps of FILE, also try
641 to rebuild the deps of all the also_make targets for that file.
642 Fixes Savannah bug #19108.
644 * implicit.c (pattern_search): Undo test for is_target, added by
645 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
646 Rule Search Algorithm". Fixes Savannah bug #17752.
648 * main.c (clean_jobserver): Clear the jobserver_fds options and
649 set job_slots to the default when we clean up.
650 (define_makeflags): Return the new MAKEFLAGS value.
651 (main): Reset MAKEFLAGS in the environment when we re-exec.
652 Fixes Savannah bug #18124.
654 2009-06-08 Paul Smith <psmith@gnu.org>
656 * read.c (eval): Collapse continuations post-semicolon on target-
657 specific variables. Fixes Savannah bug #17521.
659 2009-06-07 Paul Smith <psmith@gnu.org>
661 * job.c (reap_children): For older systems without waitpid() (are
662 there any of these left?) run wait(2) inside EINTRLOOP to handle
663 EINTR errors. Fixes Savannah bug #16401.
665 * (various): Debug message cleanup. Fixes Savannah bug #16469.
667 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
669 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
670 not the end, to catch second expansion $(eval ...) defining new
671 target/prereq relationships during snap_deps.
672 Fixes Savannah bug #24622.
674 * read.c (record_files): The second-expansion "f->updating" hack
675 was not completely correct: if assumed that the target with
676 commands always had prerequisites; if one didn't then the ordering
677 was messed up. Fixed for now to use f->updating to decide whether
678 to preserve the last element in the deps list... but this whole
679 area of constructing and reversing the deps list is too confusing
680 and needs to be reworked. Fixes Savannah bug #21198.
682 2009-06-06 Paul Smith <psmith@gnu.org>
684 * hash.c (hash_insert): Remove useless test for NULL.
685 Fixes Savannah bug #21823.
687 * make.h: Move SET_STACK_SIZE determination to make.h.
688 * main.c (main): New global variable, STACK_LIMIT, holds the
689 original stack limit when make was started.
690 * job.c (start_job_command): Reset the stack limit, if we changed it.
691 Fixes Savannah bug #22010.
693 * remake.c (check_dep): Only set the target's state to not-started
694 if it's not already running. Found this while testing -j10 builds
695 of glibc: various targets were being rebuilt multiple times.
696 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
699 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
700 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
703 2009-06-04 Paul Smith <psmith@gnu.org>
705 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
707 * maintMakefile: Modify access of config and gnulib Savannah
708 modules to use GIT instead of CVS.
710 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
711 Fixes Savannah bug #24655.
713 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
714 this can happen during some invocations of $(eval ...) for example.
715 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
717 2009-06-02 Paul Smith <psmith@gnu.org>
719 * configure.in: Check for fileno()
720 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
721 for the makefile file so invocations of $(shell ...) don't inherit it.
722 Fixes Savannah bug #24277.
724 2009-06-01 Paul Smith <psmith@gnu.org>
726 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
727 expansion was handled incorrectly. Rework the default goal
728 handling to save the variable only. Remove default_goal_file and
730 * read.c (eval): Check default_goal_var, not default_goal_name.
731 * read.c (record_target_var): Don't check default_goal_file here.
733 2009-05-31 Paul Smith <psmith@gnu.org>
735 * main.c (main): Expand the .DEFAULT_GOAL variable before using
736 it, and if the multi_glob() returns nothing (say it expanded to
737 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
739 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
740 $(and ..) to the reference. Fixes Savannah bug #25694.
742 * make.1: Be clear that some recipes will be executed even with -n.
743 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
745 * doc/make.texi (Override Directive): Make more clear how
746 overrides and appends interact.
747 Elucidates part of Savannah bug #26207.
749 * read.c (record_target_var): Don't reset the origin on
750 target-specific variables; try_variable_definition() will handle
751 this correctly. Fixes Savannah bug #26207.
753 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
754 Fixes Savannah bug #25712.
756 * implicit.c (pattern_search): Keep a pointer to the beginning of
757 the filename and save that instead of the constructed pointer.
758 Fixes Savannah bug #26593.
759 Patch by Mark Seaborn <mrs@mythic-beasts.com>
761 2009-05-30 Paul Smith <psmith@gnu.org>
763 * doc/make.texi (Multi-Line): Add a description of the new abilities
764 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
765 "command sequence" vs. "recipe" syntax.
766 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
767 after a define, to create variables with those flavors.
769 2009-05-25 Paul Smith <psmith@gnu.org>
771 Reworked the parser for variable assignments to allow multiple
772 modifiers, and in any order. Also allows variable and
773 prerequisites to be modifier names ('export', 'private', etc.)
775 * NEWS: Add notes about user-visible changes.
777 * read.c (struct vmodifiers): Remember what modifiers were seen.
778 (parse_var_assignment): New function to parse variable assignments.
779 (eval): Call the new function. Handle variable assignments earlier.
781 * variable.c (parse_variable_definition): Only parse; don't create var.
782 (assign_variable_definition): Call parse, then create the var.
784 2009-05-24 Paul Smith <psmith@gnu.org>
786 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
787 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
789 2009-03-14 Eli Zaretskii <eliz@gnu.org>
791 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
792 Fixes Savannah bug #25412.
794 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
795 prototype for xmalloc.
796 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
797 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
798 Loop over an array of extensions, instead of duplicating the same
799 code inline. Use SearchPath followed by CreateFile, instead of
800 the obsolete OpenFile. Fixes Savannah bug #17277.
801 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
802 to `find_file'. Fixes Savannah bug #25662.
804 2009-03-07 Eli Zaretskii <eliz@gnu.org>
806 * function.c (func_shell): Don't close pipedes[1] if it is -1.
807 Fixes Savannah bug #20495.
809 2009-02-28 Ralf Wildenhues <address@hidden>
811 * doc/make.texi (Instead of Execution): Document interaction of
812 -t with phony targets.
814 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
816 Introduce a new keyword "private" which applies to target-specific
817 variables and prevents their values from being inherited.
819 * variable.h (struct variable): Add private_var flag to each variable.
820 Add a flag to specify which list entry switches to the parent target.

827 * doc/make.texi (Suppressing Inheritance): Add documentation.
829 2008-10-26 Paul Smith <psmith@gnu.org>
831 * configure.in: Check for strndup().

837 * read.c (eval, record_files): Ditto.
838 * variable.c (define_variable_in_set): Ditto.
840 2008-09-30 Eli Zaretskii <eliz@gnu.org>
842 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
845 * w32/subproc/build.bat (GCCBuild): Likewise.
847 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
849 * job.c (construct_command_argv_internal): Avoid extra backslash
850 in batch-mode Unixy shells. Under DB_JOBS, display the contents
853 2008-05-31 Eli Zaretskii <eliz@gnu.org>
855 * README.W32.template: Remove obsolete text about non-support for
856 -jN without Unixy shell. Remove obsolete text about not supplying
857 Visual Studio project files (we do supply them). Modify text to
858 prefer GCC builds to MSC builds.
860 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
862 * doc/make.texi (Empty Targets): Fix typo.
864 2008-03-27 Paul Smith <psmith@gnu.org>
866 Fix Savannah bug #22379:
867 * ar.c (ar_glob_match): Zero the allocated structure.
868 * read.c (parse_file_seq): Ditto.
870 2008-03-08 Brian Dessent <brian@dessent.net>
872 * maintMakefile: Update Translation Project location.
874 2008-01-26 Eli Zaretskii <eliz@gnu.org>
876 * variable.c (target_environment): Don't use shell_var if its
877 `value' field is NULL.
879 2007-12-22 Eli Zaretskii <eliz@gnu.org>
881 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
883 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
884 (TEXINFOS): Value changed to `doc/make.texi'.
885 (.SUFFIXES): Use .texi instead of .texinfo.
886 (make.info, make.dvi): Depend on doc/make.texi.
887 (.texi.info): New target, instead of ".texinfo.info". Change -I
888 switch to $(MAKEINFO) to look in doc/. Use --no-split.
889 (.texi): New target, instead of ".texinfo". Change -I switch to
890 $(MAKEINFO) to look in doc/. Use --no-split.
891 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
892 switch to $(MAKEINFO) to look in doc/.
893 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
894 "*.i[0-9][0-9]" (due to --no-split above).
895 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
896 (html, make_1.html): New targets.
897 (.PHONY): Add "html".
898 (.SUFFIXES): Add .html.
900 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
902 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
903 HAVE_DECL_SYS_SIGLIST.
905 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
906 build does not use child_execute_job.
908 * variable.c (define_automatic_variables) [__MSDOS__]: Always
909 export the SHELL environment variable to the child.
911 2007-12-22 Eli Zaretskii <eliz@gnu.org>
913 * config.h.W32: Include sys/types.h.
914 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
916 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

920 2007-11-04 Paul Smith <psmith@gnu.org>
922 * doc/make.texi: Convert references to "commands", "command
923 lines", and "command script" to "recipe".
925 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
928 2007-10-27 Bruno Haible <bruno@clisp.org>
930 * remake.c (f_mtime): Print time difference values between 100 and
931 ULONG_MAX in fixed-point notation rather than in exponention notation.
933 2007-10-12 Eli Zaretskii <eliz@gnu.org>
935 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
936 a more complex value than a simple shell: if it's not a default
937 shell now then expand it and see if is a default shell then.
939 2007-10-10 Eli Zaretskii <eliz@gnu.org>
941 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
942 pathnames, with const strings.
943 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
944 from the template (used for building from CVS, not a dist).
946 2007-10-10 Paul Smith <psmith@gnu.org>
948 * make.h: Add a prototype for w32_kill() (change suggested by
949 Yongwei Wu <wuyongwei@gmail.com>).
951 2007-09-21 Eli Zaretskii <eliz@gnu.org>
953 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
956 2007-09-12 Paul Smith <psmith@gnu.org>
958 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
959 Provided by Diego Biurrun <diego@biurrun.de>
960 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
961 Provided by Diego Biurrun <diego@biurrun.de>
963 2007-09-11 Paul Smith <psmith@gnu.org>
965 * doc/make.texi (Special Variables): Moved this into the "How to
966 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
967 (MAKEFILE_LIST) No longer a section; this was added into the
968 "Special Variables" section.
969 (Rule Introduction): Reference .RECIPEPREFIX.
970 (Simple Makefile): Ditto.
971 (Rule Syntax): Ditto.
972 (Command Syntax): Ditto.
973 (Error Messages): Ditto.
975 2007-09-10 Paul Smith <psmith@gnu.org>
977 * commands.c (print_commands): Don't print an extra line in the
978 command scripts. Prefix the command scripts with cmd_prefix, not \t.
980 * read.c (construct_include_path): Add the full string to the cache; we
981 were chopping the last char.
983 * NEWS: Announce the .RECIPEPREFIX special variable.
984 * variable.c (lookup_special_var): Rename from handle_special_var().
985 (lookup_variable): Call the new name.
986 (set_special_var): New function: handle setting of special variables.
987 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
988 (do_variable_definition): Call it.
989 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
990 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
991 * main.c (main): Create the .RECIPEPREFIX special variable.
992 * read.c (eval): Remove the cmd_prefix characters from the command
993 scripts here, so they're not stored in the commands array at all,
994 rather than waiting and stripping them out during command construction.
995 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
997 2007-08-15 Paul Smith <psmith@gnu.org>
999 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1000 file has had the section info removed, so add some to make.texi
1001 before we include it.
1003 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1005 * remake.c (check_dep): Reset the target state for intermediate
1006 files. They might have been considered before but not updated
1007 then (order-only for example) but they will be this time.
1008 Fixes Savannah bug #'s 3330 and 15919.
1010 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1012 Fix Savannah bug #20549:
1013 * function.c (func_shell): Call construct_command_argv with zero
1015 * job.c (construct_command_argv_internal): New argument FLAGS; all
1017 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1019 * job.h (construct_command_argv_internal): Update prototype.
1021 2007-07-13 Paul Smith <psmith@gnu.org>
1023 * file.c (expand_deps): Use variable_buffer as the start of the
1024 buffer, not the original pointer (in case it was reallocated).
1025 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1026 Fixes Savannah bug #20452.
1028 2007-07-04 Paul Smith <psmith@gnu.org>
1030 * (ALL FILES): Update to GPLv3.
1031 * (ALL FILES): Update copyright for 2007.

1035 2007-06-29 Thiemo Seufer <ths@mips.com>
1037 * maintMakefile: Update Translation Project location.
1039 2007-06-13 Paul Smith <psmith@gnu.org>
1041 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1042 "Expansion of a deferred"
1043 Fixes Savannah bug #20018.
1045 * expand.c (variable_expand_for_file): Preserve the value of
1046 reading_file rather than setting it to 0 at the end.
1047 Fixes Savannah bug #20033.
1049 2007-05-11 Paul Smith <psmith@gnu.org>
1051 * job.c (new_job): Add debug info to specify where make found the
1052 command script it is running to build a target.
1053 Fixes Savannah bug #18617.
1055 * default.c (default_suffixes,default_suffix_rules,default_variables):
1056 Add support for Objective C. Fixes Savannah bug #16389.
1057 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1059 * function.c (func_lastword): Initialize p.
1061 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1062 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1063 Dave Korn <dave.korn@artimi.com>
1065 2007-05-08 Paul Smith <psmith@gnu.org>
1067 Fix Savannah bug #19656:
1069 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1071 * make.h: Change all case-insensitive string compares to use
1072 strcasecmp() (from POSIX). If we don't have that but do have one
1073 of the others, define strcasecmp to be one of those instead. If
1074 we don't have any, declare a prototype for our own version.
1076 * misc.c (strcasecmp): Use this if we can't find any native
1077 case-insensitive string comparison function.
1078 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1079 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1081 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1082 strcasecmp() instead of stricmp().
1083 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1084 instead of strcmpi().
1085 * acinclude.m4: Remove the strcasecmp() check from here.
1087 2007-03-21 Paul Smith <psmith@gnu.org>
1089 * configure.in: Don't turn on case-insensitive file system support
1090 if --disable-... is given. Fixes Savannah bug #19348.
1092 2007-03-19 Paul Smith <psmith@gnu.org>
1094 * ALL: Use the strcache for all file name strings, or other
1095 strings which we will never free. The goal is to save memory by
1096 avoiding duplicate copies of strings. However, at the moment this
1097 doesn't save much memory in most situations: due to secondary
1098 expansion we actually save prerequisite lists twice (once before
1099 the secondary expansion, and then again after it's been parsed
1100 into individual file names in the dep list). We will resolve this
1101 in a future change, by doing the parsing up-front for targets
1102 where secondary expansion is not set.
1104 Moving things into the strcache also allows us to use const
1105 pointers in many more places.
1107 2007-01-03 Paul Smith <psmith@gnu.org>
1109 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1110 the function, not just the first. Fixes Savannah bug #18680.
1112 2006-11-18 Paul Smith <psmith@gnu.org>
1114 * strcache.c (strcache_add_len): Don't allocate a new buffer
1115 unless the string is not already nil-terminated. Technically this
1116 is a violation of the standard, since we may be passed an array
1117 that is not long enough to test one past. However, in make this
1118 is never true since we only use nil-terminated strings or
1119 sub-strings thereof.
1121 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1123 * main.c: New global cmd_prefix, defaults to '\t'.
1124 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1127 * dir.c: Constified.
1128 (dir_contents_file_exists_p): Check for an error return from
1129 readdir(), just in case.
1131 * commands.c: Constified.
1132 * default.c: Constified.
1133 * expand.c: Constified.
1134 * function.c: Partial constification.

1138 * vpath.c: Partial constification.
1139 * w32/pathstuff.c: Partial constification.
1141 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1143 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1144 backslashes and drive letters as absolute.
1146 2006-10-22 Paul Smith <psmith@gnu.org>
1148 * main.c (struct command_switch): Use const and void*.
1150 2006-10-21 Paul Smith <psmith@gnu.org>
1153 * arscan.c: Constified.
1155 2006-09-30 Paul Smith <psmith@gnu.org>
1157 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1158 point to lastword since the example was updated.
1159 Fixes Savannah bug #16304.
1160 (Secondary Expansion): Correct example description.
1161 Fixes Savannah bug #16468.
1162 (Makefile Contents): Clarify that comments cannot appear within
1163 variable references or function calls.
1164 Fixes Savannah bug #16577.
1165 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1166 Fixes Savannah bug #17701.
1167 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1168 (Prerequisite Types): Added an example of using order-only
1169 prerequisites. Fixes Savannah bug #17880.
1170 (Rule Syntax): "lise" -> "list"
1171 (Multiple Rules): ... -> @dots{}
1172 (Splitting Lines): ditto.
1174 * remake.c (update_file_1): Prereqs that don't exist should be
1175 considered changed, for the purposes of $?.
1176 Fixes Savannah bug #16051.
1178 * make.1: Remove extraneous "+".

1217 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1218 that don't have extended grep.
1219 (cvsclean): Use $(PERL) instead of perl.
1221 2006-04-09 Paul D. Smith <psmith@gnu.org>
1223 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1225 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1226 inner-scope variables don't mask outer-scope variables.
1228 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1231 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1232 values from memory allocation functions: they return void* and so
1233 don't need to be cast. Also remove (char *) casts of arguments to

1248 2006-04-06 Paul D. Smith <psmith@gnu.org>

1267 Version 3.81 released.
1269 * NEWS: Updated for 3.81.
1271 * README.cvs: Mention that vpath builds are not supported out of
1272 CVS. Fixes Savannah bug #16236.
1273 Remove update of make.texi from the list of things to do; we use

1279 support from automake, as described in the Texinfo manual.
1281 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1283 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1284 with lastslash, since the latter points to filename, not to

1287 Declare and define sh_chars_sh[].
1289 2006-03-23 Paul D. Smith <psmith@gnu.org>
1291 * configure.in: Look for build.sh.in in $srcdir so it will be
1292 built for remote configurations as well.
1294 * Makefile.am: Make sure to clean up build.sh during distclean.
1295 Fixes Savannah bug #16166.
1297 * misc.c (log_access): Takes a const char *.
1298 * function.c (fold_newlines): Takes an unsigned int *.
1299 Both fixes for Savannah bug #16170.
1301 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1303 * implicit.c (pattern_search): Call set_file_variables only
1304 if we have prerequisites that need second expansion. Fixes
1305 Savannah bug #16140.
1307 2006-03-19 Paul D. Smith <psmith@gnu.org>
1309 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1310 memory on hosts that don't support it directly.
1312 * README.cvs: Add information on steps for making a release (to
1313 make sure I don't forget any).
1315 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1317 (die): Cleanup code was removed from here; call the new function.
1318 (main): If we are re-execing, clean up the jobserver first so we
1319 don't leak file descriptors.

1325 allow multiple concurrent runs.
1326 Patch from Joseph Myers <joseph@codesourcery.com>
1328 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1330 * dep.h (struct dep): Add the stem field.
1331 * misc.c (alloc_dep, free_dep): New functions.
1332 (copy_dep_chain): Copy stem.
1333 (free_dep_chain): Use free_dep.
1334 * read.c (record_files): Store stem in the dependency line.
1335 * file.c (expand_deps): Use stem stored in the dependency line. Use
1336 free_dep_chain instead of free_ns_chain.
1337 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1338 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1346 expanding the result, we expand (or not, if it's simple) each part
1348 (allocated_variable_append): Don't expand the final result.
1349 Fixes Savannah bug #15913.
1351 2006-03-09 Paul Smith <psmith@gnu.org>
1353 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1354 listed non-existent files as changed. Turns out there's a bug in
1355 the Linux kernel builds which means that this change causes
1356 everything to rebuild every time. We will re-introduce this fix
1357 in the next release, to give them time to fix their build system.
1358 Fixes Savannah bug #16002.
1359 Introduces Savannah bug #16051.
1361 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1374 to be null; don't core in that case.
1376 2006-02-19 Paul D. Smith <psmith@gnu.org>
1378 * commands.c (set_file_variables): Realloc, not malloc, the static
1379 string values to avoid memory leaks.
1381 * expand.c (recursively_expand_for_file): Only set reading_file to
1382 an initialized value.
1384 * implicit.c (pattern_search): We need to make a copy of the stem
1385 if we get it from an intermediate dep, since those get freed.
1387 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1389 (enter_file) [VMS]: Ditto.
1390 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1392 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1394 * job.c (construct_command_argv_internal): Fix last change.
1396 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1397 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1398 the calls to _beginthreadex.
1400 * expand.c (recursively_expand_for_file): Initialize `save' to
1401 prevent compiler warnings.
1403 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1405 * job.c (construct_command_argv_internal): Don't create a temporary
1406 script/batch file if we are under -n. Call _setmode to switch the
1407 script file stream to text mode.
1409 2006-02-17 Paul D. Smith <psmith@gnu.org>
1411 * variable.c (merge_variable_set_lists): Don't try to merge the
1412 global_setlist. Not only is this useless, but it can lead to
1413 circularities in the linked list, if global_setlist->next in one
1414 list gets set to point to another list which also ends in
1416 Fixes Savannah bug #15757.
1418 2006-02-15 Paul D. Smith <psmith@gnu.org>
1420 Fix for Savannah bug #106.
1422 * expand.c (expanding_var): Keep track of which variable we're
1423 expanding. If no variable is being expanded, it's the same as
1425 * make.h (expanding_var): Declare it.
1426 * expand.c (recursively_expand_for_file): Set expanding_var to the
1427 current variable we're expanding, unless there's no file info in
1428 it (could happen if it comes from the command line or a default
1429 variable). Restore it before we exit.
1430 * expand.c (variable_expand_string): Use the expanding_var file
1431 info instead of the reading_file info.

1441 * read.c (eval): Even if the included filenames expands to the
1442 empty string we still need to free the allocated buffer.
1444 * implicit.c (pattern_search): If we allocated a variable set for
1445 an impossible file, free it.
1446 * variable.c (free_variable_set): New function.
1447 * variable.h: Declare it.
1449 * read.c (read_all_makefiles): Makefile names are kept in the
1450 strcache, so there's never any need to alloc/free them.
1453 * main.c (main): Add "archives" to the .FEATURES variable if
1454 archive support is enabled.
1455 * doc/make.texi (Special Variables): Document it.
1457 2006-02-13 Paul D. Smith <psmith@gnu.org>

1465 * (ALL FILES): Updated copyright and license notices.
1467 2006-02-10 Paul D. Smith <psmith@gnu.org>
1469 A new internal capability: the string cache is a read-only cache
1470 of strings, with a hash table interface for fast lookup. Nothing
1471 in the cache will ever be freed, so there's no need for reference
1472 counting, etc. This is the beginning of a full solution for
1473 Savannah bug #15182, but for now we only store makefile names here.
1475 * strcache.c: New file. Implement a read-only string cache.
1476 * make.h: Add prototypes for new functions.
1477 * main.c (initialize_global_hash_tables): Initialize the string cache.
1478 (print_data_base): Print string cache stats.
1479 * read.c (eval_makefile): Use the string cache to store makefile
1480 names. Rewrite the string allocation to be sure we free everything.
1482 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1484 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1485 directory time stamp didn't change, except on FAT filesystems.
1486 Suggested by J. David Bryan <jdbryan@acm.org>.

1490 * function.c (func_or): Implement a short-circuiting OR function.
1491 (func_and): Implement a short-circuiting AND function.
1492 (function_table_init): Update the table with the new functions.
1493 * doc/make.texi (Conditional Functions): Changed the "if" section
1494 to one on general conditional functions. Added documentation for
1495 $(and ...) and $(or ...) functions.

1507 * vpath.c (selective_vpath_search): If the file we find has a
1508 timestamp from -o or -W, use that instead of the real time.
1509 * remake.c (f_mtime): If the mtime is a special token from -o or
1510 -W, don't overwrite it with the real mtime.

1516 (process_signal, process_last_err, process_exit_code): Manage
1517 invalid handle values.

1528 Fixes Savannah bug #15533.
1529 * filedef.h (struct file): Add a new LAST pointer.
1531 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1532 the comparison. For 64-bits systems the result of the subtraction
1533 might not fit into an int. Use comparison instead.
1534 Fixes Savannah bug #15534.
1536 * doc/make.texi: Update the chapter on writing commands to reflect
1537 the changes made in 3.81 for backslash/newline and SHELL handling.
1539 2006-02-01 Paul D. Smith <psmith@gnu.org>
1541 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1542 variable st is not used when it's not initialized.

1555 * prepare_w32.bat: Remove this file from the distribution.
1557 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1559 * remake.c (update_goal_chain): Set g->changed instead of
1560 incrementing it, as it is only 8-bit wide, and could overflow if
1561 many commands got started in update_file.
1563 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1565 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1566 MAXIMUM_WAIT_OBJECTS.

1574 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1575 are already more children than sub_proc.c can handle, behave as if
1576 the load were too high.
1577 (start_job_command): Fix a typo in error message when process_easy
1580 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1582 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1583 the shell is not sh.exe.
1585 * job.c (create_batch_file): Renamed from create_batch_filename;
1586 all callers changed. Don't close the temporary file; return its
1587 file descriptor instead. New arg FD allows to return the file
1589 (construct_command_argv_internal): Use _fdopen instead of fopen to
1590 open the batch file.
1592 2006-01-04 Paul D. Smith <psmith@gnu.org>
1594 * readme.vms: Updates for case-insensitive VMS file systems from
1595 Hartmut Becker <Hartmut.Becker@hp.com>.
1596 * dir.c (vms_hash): Ditto.
1597 * vmsify.c (copyto): Ditto.
1598 * vmsfunctions.c (readdir): Ditto.
1600 * make.1: Add a section on the exit codes for make.
1602 * doc/make.texi: A number of minor updates to the documentation.
1604 2006-01-03 Paul D. Smith <psmith@gnu.org>
1606 * remake.c (update_file_1): Mark a prerequisite changed if it
1609 * read.c (eval): Be sure to strip off trailing whitespace from the
1610 prerequisites list properly. Also, initialize all fields in
1611 struct dep when creating a new one.
1613 2005-12-28 Paul D. Smith <psmith@gnu.org>
1615 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1616 disable warnings for MSC.
1617 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1619 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1621 * doc/make.texi (Execution): Add a footnote about changes in
1622 handling of backslash-newline sequences. Mention the differences
1623 on MS-DOS and MS-Windows.
1625 * NEWS: More details about building the MinGW port and a pointer
1626 to README.W32. Fix the section name that describes the new
1627 backward-incompatible processing of backslash-newline sequences.
1628 The special processing of SHELL set to "cmd" is only relevant to
1629 MS-Windows, not MS-DOS.
1631 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1633 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1634 to DWORD, to avoid compiler warnings.
1635 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1636 use %ld in format, to avoid compiler warnings.
1638 * doc/make.texi (Special Targets): Fix a typo.
1639 (Appending): Fix cross-reference to Setting.
1640 (Special Variables, Secondary Expansion, File Name Functions)
1641 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1642 periods after a sentence.
1643 (Execution): Add @: after "e.g.".
1644 (Environment): Fix punctuation.
1645 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1646 (Shell Function, Target-specific): Add @: after "vs."
1648 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1650 * read.c (record_target_var): Initialize variable's export field
1651 with v_default instead of leaving it "initialized" by whatever
1652 garbage happened to be on the heap.
1654 2005-12-12 Paul D. Smith <psmith@gnu.org>
1656 * make.1: Fix some display errors and document all existing options.
1657 Patch by Mike Frysinger <vapier@gentoo.org>.
1659 2005-12-11 Paul D. Smith <psmith@gnu.org>
1661 * implicit.c (pattern_search): If 2nd expansion is not set for
1662 this implicit rule, replace the pattern with the stem directly,
1663 and don't re-expand the variable list. Along with the other
1664 .SECONDEXPANSION changes below, fixes bug #13781.
1666 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1668 * implicit.c (pattern_search): Mark other files that this rule
1669 builds as targets so that they are not treated as intermediates
1670 by the pattern rule search algorithm. Fixes bug #13022.
1672 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1674 * remake.c (notice_finished_file): Propagate the change of
1675 modification time to all the double-colon entries only if
1676 it is the last one to be updated. Fixes bug #14334.
1678 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1680 * function.c (func_flavor): Implement the flavor function which
1681 returns the flavor of a variable.
1682 * doc/make.texi (Functions for Transforming Text): Document it.
1683 * NEWS: Add it to the list of new functions.
1685 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1687 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1689 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1690 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1692 2005-10-26 Paul Smith <psmith@gnu.org>
1694 * read.c (record_files): Don't set deps flags if there are no deps.
1695 * maintMakefile: We only need to build the templates when we are
1696 creating a distribution, so don't do it for "all".
1698 2005-10-24 Paul D. Smith <psmith@gnu.org>
1700 Make secondary expansion optional: its enabled by declaring the
1701 special target .SECONDEXPANSION.
1703 * NEWS: Update information on second expansion capabilities.
1704 * doc/make.texi (Secondary Expansion): Document the
1705 .SECONDEXPANSION special target and its behavior.
1706 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1707 prerequisite list was found in a static pattern rule.
1708 (free_dep_chain): Declare a prototype.
1709 * file.c (parse_prereqs): New function: break out some complexity
1711 (expand_deps): If we aren't doing second expansion, replace % with
1712 the stem for static pattern rules. Call the new function.
1713 * filedef.h (parse_prereqs): Declare a prototype.
1714 * implicit.c (pattern_search): Initialize the new staticpattern
1716 * main.c (second_expansion): Declare a global variable to remember
1717 if the special target has been seen. Initialize the new
1718 staticpattern field for prerequisites.
1719 * make.h: Extern for second_expansion.
1720 * misc.c (free_dep_chain): New function: frees a struct dep list.
1721 * read.c (read_all_makefiles): Initialize the staticpattern field.
1722 (eval_makefile): Ditto.
1723 (record_files): Check for the .SECONDEXPANSION target and set
1724 second_expansion global if it's found.
1725 Use the new free_dep_chain() instead of doing it by hand.
1726 Set the staticpattern field for prereqs of static pattern targets.
1728 2005-10-16 Paul D. Smith <psmith@gnu.org>
1730 * main.c (main): Set CURDIR to be a file variable instead of a
1731 default, so that values of CURDIR inherited from the environment
1732 won't override the make value.
1734 2005-09-26 Paul D. Smith <psmith@gnu.org>
1736 * job.c (construct_command_argv_internal): If the line is empty
1737 remember to free the temporary argv strings.
1740 2005-09-16 Paul D. Smith <psmith@gnu.org>
1742 * job.c (start_job_command): The noerror flag is a boolean (single
1743 bit); set it appropriately.
1744 Reported by Mark Eichin <eichin@metacarta.com>
1746 2005-08-29 Paul D. Smith <psmith@gnu.org>
1748 * function.c (func_error): On Windows, output from $(info ...)
1749 seems to come in the wrong order. Try to force it with fflush().
1751 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1753 * read.c (record_files): Move code that sets stem for static
1754 pattern rules out of the if (!two_colon) condition so it is
1755 also executed for two-colon rules. Fixes Savannah bug #13881.
1757 2005-08-08 Paul D. Smith <psmith@gnu.org>
1759 * make.h: Don't test that __STDC__ is non-0. Some compilers
1760 (Windows for example) set it to 0 to denote "ISO C + extensions".
1763 2005-08-07 Paul D. Smith <psmith@gnu.org>
1765 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1766 conditional (slightly different version of a fix from Eli).
1768 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1769 If make is running in parallel without -k and two jobs die in a
1770 row, but not too close to each other, then make will quit without
1771 waiting for the rest of the jobs to die.
1773 * main.c (die): Don't reset err before calling reap_children() the
1774 second time: we still want it to be in the error condition.
1775 * job.c (reap_children): Use a static variable, rather than err,
1776 to control whether or not the error message should be printed.
1778 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1780 * w32/subproc/sub_proc.c: Include signal.h.
1781 (process_pipe_io, process_file_io): Pass a pointer to a local
1782 DWORD variable to GetExitCodeProcess. If the exit code is
1783 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1785 * job.c [WINDOWS32]: Include windows.h.
1786 (main_thread) [WINDOWS32]: New global variable.
1787 (reap_children) [WINDOWS32]: Get the handle for the main thread
1788 and store it in main_thread.
1790 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1791 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1792 doing anything else. When we are done, close the main thread
1793 handle and exit with status 130.
1795 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1797 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1800 * main.c (find_and_set_default_shell): If found a DOSish shell,
1801 set sh_found and the value of default_shell, and report the
1802 findings in debug mode.
1804 * job.c (construct_command_argv_internal): Check unixy_shell, not
1805 no_default_sh_exe, to decide whether to use Unixy or DOSish
1808 * README.W32: Update with info about the MinGW build.
1810 * build_w32.bat: Support MinGW.
1812 * w32/subproc/build.bat: Likewise.
1814 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1815 printing DWORD args.
1817 * function.c (windows32_openpipe): Fix format strings for printing
1820 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1822 (start_job_command): Fix format string for printing the result of
1824 (start_job_command) [WINDOWS32]: Do not define.
1825 (exec_command): Fix format string for printing HANDLE args.
1827 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1828 to avoid compiler warnings.
1829 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1830 (Note: some of these fixes were submitted independently by J. Grant)
1832 2005-07-30 J. Grant <jg@jguk.org>
1834 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1835 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1836 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1838 2005-07-15 Paul Smith <psmith@gnu.org>
1840 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1841 we don't have a POSIX shell, then revert to the old
1842 backslash-newline behavior (where they are stripped).
1845 2005-07-08 Paul D. Smith <psmith@gnu.org>
1847 * config.h.W32.template: Reorder to match the standard config.h,
1848 for easier comparisons.
1849 From J. Grant <jg@jguk.org>
1851 * maintMakefile: Remove .dep_segment before overwriting it, in
1852 case it's not writable or noclobber is set.
1853 * expand.c (variable_expand_string): Cast result of pointer
1854 arithmetic to avoid a warning.
1855 * main.c (switches): Add full-fledged final initializer.
1857 2005-07-06 Paul D. Smith <psmith@gnu.org>
1859 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1860 * signame.c (strsignal): If we found _sys_siglist[] or
1861 __sys_siglist[] use those instead of sys_siglist[].
1862 From Albert Chin <china@thewrittenword.com>
1864 2005-07-04 Paul D. Smith <psmith@gnu.org>
1866 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1867 globfree(); set up to use the GNU versions.
1868 From Martin Zinser <zinser@zinser.no-ip.info>
1870 2005-07-03 Paul D. Smith <psmith@gnu.org>
1872 From J. Grant <jg@jguk.org>:
1874 * README.W32.template: Update the Windows and tested MSVC versions.
1875 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1876 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1877 * build_w32.bat: Ditto.
1878 * w32/subproc/build.bat: Ditto.
1880 2005-06-28 Paul D. Smith <psmith@gnu.org>
1882 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1883 declaration was checked but not present.
1885 2005-06-27 Paul D. Smith <psmith@gnu.org>
1887 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1888 to unsigned long. Fixes Savannah bug #13550.
1890 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1891 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1892 Fixes Savannah bug #13551.
1894 2005-06-26 Paul D. Smith <psmith@gnu.org>
1896 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1897 it if ANSI_STRING is not set.
1899 2005-06-25 Paul D. Smith <psmith@gnu.org>
1901 * read.c (eval): If no filenames are passed to any of the
1902 "include" variants, don't print an error.
1903 * doc/make.texi (Include): Document this.
1904 Fixes Savannah bug #1761.
1906 * job.c (construct_command_argv_internal): Sanitize handling of
1907 backslash/newline pairs according to POSIX: that is, keep the
1908 backslash-newline in the command script, but remove a following
1909 TAB character, if present. In the fast path, make sure that the
1910 behavior matches what the shell would do both inside and outside
1911 of quotes. In the slow path, quote the backslash and put a
1912 literal newline in the string.
1913 Fixes Savannah bug #1332.
1914 * doc/make.texi (Execution): Document the new behavior and give
1916 * NEWS: Make a note of the new behavior.
1918 * make.h [WINDOWS32]: #include <direct.h>.
1919 Fixes Savannah bug #13478.
1921 * remake.c (name_mtime): If the stat() of a file fails and the -L
1922 option was given and the file is a symlink, take the best mtime of
1923 the symlink we can get as the mtime of the file and don't fail.
1924 Fixes Savannah bug #13280.
1926 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1927 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1928 inside a variable reference. Make this function static as it's
1930 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1931 parsing an unexpanded line looking for semicolons.
1932 Fixes Savannah bug #1454.
1933 * misc.c (remove_comments): Move this to read.c and make it static
1934 as it's only used there. Call find_char_unquote() with new arg.
1935 * make.h: Remove prototypes for find_char_unquote() and
1936 remove_comments() since they're static now.
1938 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1939 its export flag and obtain its value. When we need to re-exec,
1940 increment the value and add it into the environment.
1941 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1942 * NEWS: Mention MAKE_RESTARTS.
1943 * main.c (always_make_set): New variable. Change the -B option to
1944 set this one instead.
1945 (main): When checking makefiles, only set always_make_flag if
1946 always_make_set is set AND the restarts flag is 0. When building
1947 normal targets, set it IFF always_make_set is set.
1948 (main): Avoid infinite recursion with -W, too: only set what-if
1949 files to NEW before we check makefiles if we've never restarted
1950 before. If we have restarted, set what-if files to NEW _after_ we
1952 Fixes Savannah bug #7566:
1954 2005-06-17 Paul D. Smith <psmith@gnu.org>
1956 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1957 in the prerequisites list.
1959 2005-06-12 Paul D. Smith <psmith@gnu.org>
1961 Fix Savannah bug # 1328.
1963 * configure.in: Check for atexit().
1964 * misc.c (close_stdout): Test stdout to see if writes to it have
1965 failed. If so, be sure to exit with a non-0 error code. Based on
1966 code found in gnulib.
1967 * make.h: Prototype.
1968 * main.c (main): Install close_stdout() with atexit().
1970 2005-06-10 Paul D. Smith <psmith@gnu.org>
1972 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1974 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1975 headers; make vmsWaitForChildren() static; extern vmsify().
1976 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1977 Don't create child_execute_job() here (it's in vmsjobs.c).
1978 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1980 2005-06-09 Paul D. Smith <psmith@gnu.org>
1982 * variable.c (push_new_variable_scope): File variables point
1983 directly to the global_setlist variable. So, inserting a new
1984 scope in front of that has no effect on those variables: they
1985 don't go through current_variable_set_list. If we're pushing a
1986 scope and the current scope is global, push it "the other way" so
1987 that the new setlist is in the global_setlist variable, and
1988 next points to a new setlist with the global variable set.
1989 (pop_variable_scope): Properly undo a push with the new
1991 Fixes Savannah bug #11913.
1993 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1995 * job.c (reap_children): Don't die of the command failed but
1996 the dontcare flag is set. Fixes Savannah bug #13216.
1998 * implicit.c (pattern_search): When creating a target from
1999 an implicit rule match, lookup pattern target and set precious
2000 flag in a newly created target. Fixes Savannah bug #13218.
2002 2005-05-13 Paul D. Smith <psmith@gnu.org>
2004 Implement "if... else if... endif" syntax.
2006 * read.c (eval): Push all checks for conditional words ("ifeq",
2007 "else", etc.) down into the conditional_line() function.
2008 (conditional_line): Rework to allow "else if..." clause. New
2009 return value -2 for lines which are not conditionals. The
2010 ignoring flag can now also be 2, which means "already parsed a
2011 true branch". If that value is seen no other branch of this
2012 conditional can be considered true. In the else parsing if there
2013 is extra text after the else, invoke conditional_line()
2014 recursively to see if it's another conditional. If not, it's an
2015 error. If so, raise the conditional value to this level instead
2016 of creating a new conditional nesting level. Special check for
2017 "else" and "endif", which aren't allowed on the "else" line.
2018 * doc/make.texi (Conditional Syntax): Document the new syntax.
2020 2005-05-09 Paul D. Smith <psmith@gnu.org>
2022 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2023 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2024 recurses to the w32 directory, even on non-Windows systems. Use
2025 the method suggested in the automake manual.
2026 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2027 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2029 2005-05-07 Paul D. Smith <psmith@gnu.org>
2031 * main.c (die): If we're dying with a fatal error (not that a
2032 command has failed), write back any leftover tokens before we go.
2034 * job.c (set_child_handler_action_flags): If there are jobs
2035 waiting for the load to go down, set an alarm to go off in 1
2036 second. This allows us to wake up from a potentially long-lasting
2037 read() and start a new job if the load has gone down. Turn it off
2039 (job_noop): Dummy signal handler function.
2040 (new_job): Invoke it with the new semantics.
2042 * docs/make.texi: Document secondary expansion. Various cleanups
2045 2005-05-03 Paul D. Smith <psmith@gnu.org>
2047 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2048 the targets which are to ultimately be made are called "goals";
2049 see the GNU make manual. Also, MAKECMDGOALS, etc.
2051 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2052 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2053 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2055 2005-05-02 Paul D. Smith <psmith@gnu.org>
2057 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2058 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2059 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2060 functions to vmsjobs.c. #include it into jobs.c.
2062 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2063 jobserver tokens. I found that this happens when an exported
2064 recursive variable contains a $(shell ...) function reference: in
2065 this situation we could "forget" to write back a token.
2067 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2068 we have. It's not reliable to depend on the number of children in
2069 our linked list so keep a separate count.
2070 (new_job): Check jobserver_tokens rather than children &&
2071 waiting_jobs. Increment jobserver_tokens when we get one.
2072 (free_child): If jobserver_tokens is 0, internal error. If it's
2073 >1, write a token back to the jobserver pipe (we don't write a
2074 token for the "free" job). Decrement jobserver_tokens.
2076 * main.c: Add variable master_job_slots.
2077 (main): Set it to hold the number of jobs requested if we're the
2078 master process, when using the jobserver.
2079 (die): Sanity checks: first test jobserver_tokens to make sure
2080 this process isn't holding any tokens we didn't write back.
2081 Second, if master_job_slots is set count the tokens left in the
2082 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2084 2005-04-24 Paul D. Smith <psmith@gnu.org>
2086 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2087 with -l# can lose jobserver tokens, because waiting jobs are not
2088 consulted properly when checking for the "free" token.
2090 * job.c (free_child): Count waiting_jobs as having tokens.
2091 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2092 handle jobs waiting for the load to drop.
2094 2005-04-23 Paul D. Smith <psmith@gnu.org>
2096 * main.c (main): Be careful to not core if a variable setting in
2097 the environment doesn't contain an '='. This is illegal but can
2098 happen in broken setups.
2099 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2101 2005-04-12 Paul D. Smith <psmith@gnu.org>
2103 The second expansion feature causes significant slowdown. Timing
2104 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2105 read the makefile before the feature, to 11+s to do the same
2106 operations after the feature. Additionally, memory usage
2107 increased drastically. To fix this I added some intelligence that
2108 avoids the overhead of the second expansion unless it's required.
2110 * dep.h: Add a new boolean field, need_2nd_expansion.
2112 * read.c (eval): When creating the struct dep for the target,
2113 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2114 (record_files): If there's a "%" in a static pattern rule, it gets
2115 converted to "$*" so set need_2nd_expansion to 1.
2117 * file.c (expand_deps): Rework to be more efficient. Only perform
2118 initialize_file_variables(), set_file_variables(), and
2119 variable_expand_for_file() if the need_2nd_expansion is set.
2121 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2122 (pattern_search): Ditto.
2123 * main.c (handle_non_switch_argument): Ditto.
2125 * read.c (read_all_makefiles): Ditto.
2126 (eval_makefile): Ditto.
2128 2005-04-07 Paul D. Smith <psmith@gnu.org>
2130 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2131 * variable.c (sync_Path_environment): Ditto.
2132 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2134 * main.c (main): Define the .FEATURES variable.
2135 * NEWS: Announce .FEATURES.
2136 * doc/make.texi (Special Variables): Document .FEATURES.
2138 * remake.c (check_dep): If a file is .PHONY, update it even if
2139 it's marked intermediate. Fixes Savannah bug #12331.
2141 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2143 * file.c (expand_deps): Factor out the second expansion and
2144 prerequisite line parsing logic from snap_deps().
2146 * file.c (snap_deps): Use expand_deps(). Expand and parse
2147 prerequisites of the .SUFFIXES special target first. Fixes
2148 Savannah bug #12320.
2150 2005-03-13 Paul D. Smith <psmith@gnu.org>
2152 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2155 2005-03-11 Paul D. Smith <psmith@gnu.org>
2157 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2158 available, not undefined (from Earnie Boyd).
2160 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2162 * implicit.c (pattern_search): Mark an intermediate target as
2163 precious if it happened to be a prerequisite of some (other)
2164 target. Fixes Savannah bug #12267.
2166 2005-03-09 Paul D. Smith <psmith@gnu.org>
2168 * read.c (eval_makefile): Add alloca(0).
2169 (eval_buffer): Ditto.
2171 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2173 * main.c (main): Use o_file instead of o_default when defining
2174 the .DEFAULT_TARGET special variable.
2175 * read.c (eval): Use define_variable_global() instead of
2176 define_variable() when setting new value for the .DEFAULT_TARGET
2177 special variable. Fixes Savannah bug #12266.
2179 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2181 * imlicit.c (pattern_search): Mark files for which an implicit
2182 rule has been found as targets. Fixes Savannah bug #12202.
2184 2005-03-04 Paul D. Smith <psmith@gnu.org>
2187 * doc/make.texi (Automatic Variables): Document $|.
2189 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2191 * read.c (record_files): Instead of substituting % with
2192 actual stem value in dependency list replace it with $*.
2193 This fixes stem triple expansion bug.
2195 * implicit.c (pattern_search): Copy stem to a separate
2196 buffer and make it a properly terminated string. Assign
2197 this buffer instead of STEM (which is not terminated) to
2198 f->stem. Instead of substituting % with actual stem value
2199 in dependency list replace it with $*. This fixes stem
2200 triple expansion bug.
2202 2005-03-01 Paul D. Smith <psmith@gnu.org>
2204 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2205 on Windows, as it takes a handle not a pid. Just exit.
2206 Fix from patch #3679, provided by Alessandro Vesely.
2208 * configure.in: Update check for sys_siglist[] from autoconf manual.
2209 * signame.c (strsignal): Update to use the new autoconf macro.
2211 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2213 * read.c (record_files): Add a check for the list of prerequisites
2214 of a static pattern rule being empty. Fixes Savannah bug #12180.
2216 2005-02-28 Paul D. Smith <psmith@gnu.org>
2218 * doc/make.texi (Text Functions): Update docs to allow the end
2219 ordinal for $(wordlist ...) to be 0.
2220 * function.c (func_wordlist): Fail if the start ordinal for
2221 $(wordlist ...) is <1. Matches documentation.
2222 Resolves Savannah support request #103195.
2224 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2225 previously we were stopping when !-q, exactly the opposite. This
2226 has been wrong since version 1.34, in 1994!
2227 (update_file): If we got an error don't break out to run more
2228 double-colon rules: just return immediately.
2229 Fixes Savannah bug #7144.
2231 2005-02-27 Paul D. Smith <psmith@gnu.org>
2233 * misc.c (end_of_token): Make argument const.
2234 * make.h: Update prototype.
2236 * function.c (abspath, func_realpath, func_abspath): Use
2237 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2238 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2239 * read.c (record_files): Ditto.
2240 * variable.c (do_variable_definition): Ditto.
2242 * function.c (func_error): Create a new function $(info ...) that
2243 simply prints the message to stdout with no extras.
2244 (function_table_init): Add new function to the table.
2245 * NEWS: Add $(info ...) reference.
2246 * doc/make.texi (Make Control Functions): Document it.
2248 New feature: if the system supports symbolic links, and the user
2249 provides the -L/--check-symlink-time flag, then use the latest
2250 mtime between the symlink(s) and the target file.
2252 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2253 readlink(). If both are available, define MAKE_SYMLINKS.
2254 * main.c: New variable: check_symlink_flag.
2255 (usage): Add a line for -L/--check-symlink-times to the help string.
2256 (switches): Add -L/--check-symlink-times command line argument.
2257 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2258 print a warning and disable it again.
2259 * make.h: Declare check_symlink_flag.
2260 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2261 if the file is a symlink then check each link in the chain and
2262 choose the NEWEST mtime we find as the mtime for the file. The
2263 newest mtime might be the file itself!
2264 * NEWS: Add information about this new feature.
2265 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2267 Avoid core dumps described in Savannah bug # 12124:
2269 * file.c: New variable snapped_deps remember whether we've run
2271 (snap_deps): Set it.
2272 * filedef.h: Extern it.
2273 * read.c (record_files): Check snapped_deps; if it's set then
2274 we're trying to eval a new target/prerequisite relationship from
2275 within a command script, which we don't support. Fatal.
2277 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2279 Implementation of the .DEFAULT_TARGET special variable.
2281 * read.c (eval): If necessary, update default_target_name when
2283 * read.c (record_files): Update default_target_file if
2284 default_target_name has changed.
2285 * main.c (default_target_name): Define.
2286 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2287 default_target_name is set use default_target_file as a root
2289 * filedef.h (default_target_name): Declare.
2290 * dep.h (free_dep_chain):
2291 * misc.c (free_dep_chain): Change to operate on struct nameseq
2292 and change name to free_ns_chain.
2293 * file.c (snap_deps): Update to use free_ns_chain.
2295 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2297 Implementation of the second expansion in explicit rules,
2298 static pattern rules and implicit rules.
2300 * read.c (eval): Refrain from chopping up rule's dependencies.
2301 Store them in a struct dep as a single dependency line. Remove
2302 the code that implements SySV-style automatic variables.
2304 * read.c (record_files): Adjust the code that handles static
2305 pattern rules to expand all percents instead of only the first
2306 one. Reverse the order in which dependencies are stored so that
2307 when the second expansion reverses them again they appear in
2308 the makefile order (with some exceptions, see comments in
2309 the code). Remove the code that implements SySV-style automatic
2312 * file.c (snap_deps): Implement the second expansion and chopping
2313 of dependency lines for explicit rules.
2315 * implicit.c (struct idep): Define an auxiliary data type to hold
2316 implicit rule's dependencies after stem substitution and
2319 * implicit.c (free_idep_chain): Implement.
2321 * implicit.c (get_next_word): Implement helper function for
2322 parsing implicit rule's dependency lines into words taking
2323 into account variable expansion requests. Used in the stem
2326 * implicit.c (pattern_search): Implement the second expansion
2327 for implicit rules. Also fixes bug #12091.
2329 * commands.h (set_file_variables): Declare.
2330 * commands.c (set_file_variables): Remove static specifier.
2332 * dep.h (free_dep_chain): Declare.
2333 * misc.c (free_dep_chain): Implement.
2335 * variable.h (variable_expand_for_file): Declare.
2336 * expand.c (variable_expand_for_file): Remove static specifier.
2338 * make.h (strip_whitespace): Declare.
2339 * function.c (strip_whitespace): Remove static specifier.
2341 2005-02-26 Paul D. Smith <psmith@gnu.org>
2343 * main.c (main): Check for ferror() when reading makefiles from stdin.
2344 Apparently some shells in Windows don't close pipes properly and
2347 2005-02-24 Jonathan Grant <jg@jguk.org>
2349 * configure.in: Add MinGW configuration options, and extra w32 code
2351 * Makefile.am: Add MinGW configuration options, and extra w32 code
2353 * main.c: Determine correct program string (after last \ without .exe).
2354 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2356 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2357 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2358 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2359 environment support.
2361 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2363 * function.c (func_shell): When initializing error_prefix, check
2364 that reading file name is not null. This fixes long-standing
2365 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2367 2005-02-09 Paul D. Smith <psmith@gnu.org>
2369 * maintMakefile: Update the CVS download URL to simplify them.
2370 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2371 downloading the .texi files from Savannah now.
2373 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2375 * main.c (handle_non_switch_argument): Only add variables to
2376 command_variables if they're not already there: duplicate settings
2377 waste space and can be confusing to read.
2379 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2380 this header is never included by non-WINDOWS32 code, and it
2381 requires <config.h> to define which isn't always included first.
2383 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2384 testing MINGW32 versions.
2386 * main.c (log_working_directory): flush stdout to be sure the WD
2387 change is printed before any stderr messages show up.
2389 2005-02-01 Paul D. Smith <psmith@gnu.org>
2391 * maintMakefile (po_repo): Update the GNU translation site URL.
2393 2004-12-01 Paul D. Smith <psmith@gnu.org>
2395 * main.c (main): Change char* env_shell to struct variable shell_var.
2396 * variable.c (target_environment): Use new shell_var.
2398 2004-11-30 Paul D. Smith <psmith@gnu.org>
2400 * configure.in: The old way we avoided creating build.sh from
2401 build.sh.in before build.sh.in exists doesn't work anymore; we
2402 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2403 the help!). This also keeps automake from complaining.
2404 * Makefile.am (README): Add a dummy target so automake won't
2405 complain that this file doesn't exist when we checkout from CVS.
2406 * maintMakefile (.dep_segment): Rewrite this rule since newer
2407 versions of automake don't provide DEP_FILES.
2409 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2411 Implementation of `realpath' and `abspath' built-in functions.
2413 * configure.in: Check for realpath.
2414 * function.c (abspath): Return an absolute file name that does
2415 not contain any `.' or `..' components, nor repeated `/'.
2416 * function.c (func_abspath): For each name call abspath.
2417 * function.c (func_realpath): For each name call realpath
2418 from libc or delegate to abspath if realpath is not available.
2419 * doc/make.texi (Functions for File Names): Document new functions.
2420 * doc/make.texi (Quick Reference): Ditto.
2422 2004-11-28 Paul D. Smith <psmith@gnu.org>
2424 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2425 arguments. Fixes bug #10252.
2427 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2429 * main.c (main): Set SHELL to v_noexport by default. Remember the
2430 original environment setting of SHELL in the env_shell variable.
2431 * main.h: Export new env_shell variable.
2432 * variable.c (target_environment): If we find a v_noexport
2433 variable for SHELL, add a SHELL variable with the env_shell value.
2434 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2435 * doc/make.texi (Variables/Recursion): Ditto.
2437 2004-11-28 Paul D. Smith <psmith@gnu.org>
2439 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2440 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2441 Patch by Alessandro Vesely.
2443 2004-11-12 Paul D. Smith <psmith@gnu.org>
2445 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2446 the command line if it's inside a string.
2447 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2449 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2451 * function.c (func_lastword): New function: return last word
2452 from the list of words.
2453 * doc/make.texi: Document $(lastword ). Fix broken links in
2454 Quick Reference section.
2456 2004-10-06 Paul D. Smith <psmith@gnu.org>
2458 Apply patch from Alessandro Vesely, provided with bug # 9748.
2459 Fix use of tmpnam() to work with Borland C.
2461 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2462 construction of a temporary filename, and call new function
2463 create_batch_filename().
2464 (create_batch_filename) [WINDOWS32]: New function to create a
2467 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2469 * read.c (record_target_var): Expand simple pattern-specific
2471 * variable.c (initialize_file_variables): Do not expand simple
2472 pattern-specific variable.
2474 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2476 * remake.c (update_file_1): When rebuilding makefiles inherit
2477 dontcare flag from a target that triggered update.
2479 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2481 * variable.c (initialize_file_variables): Mark pattern-specific
2482 variable as a per-target and copy export status.
2484 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2486 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2488 * implicit.c (pattern_search): When considering an implicit rule's
2489 prerequisite check that it is actually a target rather then
2490 just an entry in the file hashtable.
2492 2004-09-21 Paul D. Smith <psmith@gnu.org>
2494 * read.c (readstring): Fix some logic errors in backslash handling.
2495 (eval): Remove some unnecessary processing in buffer handling.
2496 (record_target_var): Assert that parse_variable_definition() succeeded.
2497 Reported by: Markus Mauhart <qwe123@chello.at>.
2499 * misc.c: Removed the sindex() function. All instances of this
2500 function were trivially replaceable by the standard strstr()
2501 function, and that function will always have better (or certainly
2502 no worse) performance than the very simple-minded algorithm
2503 sindex() used. This can matter with complex makefiles.
2504 * make.h: Remove the prototype for sindex().
2505 * function.c (subst_expand): Convert sindex() call to strstr().
2506 This means we no longer need to track the TLEN value so remove that.
2507 (func_findstring): Convert sindex() to strstr().
2508 * commands.c (chop_commands): Convert sindex() calls to strstr().
2509 Suggested by: Markus Mauhart <qwe123@chello.at>.
2511 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2512 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2513 If SHELL is set to CMD.EXE then assume it's batch-mode and
2514 non-unixy. I wrote the code differently from the patch, though,
2515 to make it safer. This also resolves bug #9174.
2517 2004-09-20 Paul D. Smith <psmith@gnu.org>
2519 * expand.c (variable_expand_string): Modify to invoke
2520 patsubst_expand() instead of subst_expand(); the latter didn't
2521 handle suffix patterns correctly.
2522 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2523 was used only from variable_expand_string() and is no longer used
2525 (func_subst): Ditto, on call to subst_expand().
2526 (patsubst_expand): Require the percent pointers to point to the
2527 character after the %, not to the % itself.
2528 * read.c (record_files): New call criteria for patsubst_expand().
2529 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2530 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2532 2004-09-19 Paul D. Smith <psmith@gnu.org>
2534 * function.c (subst_expand): Fix a check in by_word: look for a
2535 previous blank if we're beyond the beginning of the string, not
2536 the beginning of the word.
2537 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2539 2004-05-16 Paul D. Smith <psmith@gnu.org>
2541 * remake.c (update_goal_chain): Change the argument specifying
2542 whether we're rebuilding makefiles to be a global variable,
2543 REBUILDING_MAKEFILES.
2544 (complain): Extract the code that complains about no rules to make
2545 a target into a separate function.
2546 (update_file_1): If we tried to rebuild a file during the makefile
2547 rebuild phase and it was dontcare, then no message was printed.
2548 If we then try to build the same file during the normal build,
2549 print a message this time.
2550 (remake_file): Don't complain about un-remake-able files when
2551 we're rebuilding makefiles.
2553 2004-05-11 Paul D. Smith <psmith@gnu.org>
2555 * job.c (construct_command_argv_internal): OS/2 patches from
2556 Andreas Buening <andreas.buening@nexgo.de>.
2558 2004-05-10 Paul D. Smith <psmith@gnu.org>
2560 * remake.c (update_file): Don't walk the double-colon chain unless
2561 this is a double-colon rule. Fix suggested by Boris Kolpackov
2562 <boris@kolpackov.net>.
2564 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2565 * readme.vms: New section describing OpenVMS support and issues.
2566 * default.c (default_variables): Add support for IA64.
2567 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2568 without some privilege aborts make with the error
2569 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2570 pressing Ctrl+Y and the input device is no terminal. The change
2571 catches this error and just continues.
2573 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2575 2004-04-25 Paul D. Smith <psmith@gnu.org>
2577 * commands.c (set_file_variables): Set $< properly in the face of
2578 order-only prerequisites.
2579 Patch from Boris Kolpackov <boris@kolpackov.net>
2581 2004-04-21 Bob Byrnes <byrnes@curl.com>
2583 * main.c (main): Notice failures to remake makefiles.
2585 2004-03-28 Paul D. Smith <psmith@gnu.org>
2587 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2589 * job.c: No default shell for RISC OS.
2590 (load_too_high): Hard-code the return to 1.
2591 (construct_command_argv_internal): No sh_chars or sh_cmds.
2592 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2594 2004-03-20 Paul D. Smith <psmith@gnu.org>
2596 * variable.c (do_variable_definition): Don't append from the
2597 global set if a previous non-appending target-specific variable
2598 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2601 * expand.c (reference_variable): Don't give up on variables with
2602 no value that have the target-specific append flag set: they might
2603 have a value after all. Reported by Oliver Schmidt
2604 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2605 <nikulin@dx1cmd.inp.nsk.su>.
2607 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2608 refer to absolute pathnames in directories that don't exist: some
2609 portion of the makefile could create those directories before we
2610 match the pattern. Fixes bugs #775 and #108.
2612 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2614 * main.c (main): Free makefile_mtimes if we have any.
2615 * README.W32.template: Update documentation for the current status
2616 of the MS-Windows port.
2617 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2618 environment variable is sometimes already defined which causes the
2620 * main.c (debug_signal_handler): Only define this function if
2621 SIGUSR1 is available.
2623 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2625 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2626 * README.OS2.template: Documentation updates.
2627 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2628 link line for safety.
2629 * maintMakefile (build.sh.in): Remove an extraneous ")".
2630 * job.c (child_execute_job): Close saved FDs.
2631 * job.c (exec_command) [OS/2]: exec_command(): If the command
2632 can't be exec'ed and if the shell is not Unix-sh, then try again
2633 with argv = { "cmd", "/c", ... }. Normally, this code is never
2634 reached for the cmd shell unless the command really doesn't exist.
2635 (construct_command_argv_internal) [OS/2]: The code for cmd
2636 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2637 The CMD builtin commands are case insensitive so use strcasecmp().
2639 2004-03-19 Paul D. Smith <psmith@gnu.org>
2641 * read.c (do_define): Re-order line counter increment so the count
2642 is accurate (we were losing one line per define). Reported by
2643 Dave Yost <Dave@Yost.com>.
2645 2004-03-06 Paul D. Smith <psmith@gnu.org>
2647 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2649 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2650 * misc.c (message,error,fatal): Ditto.
2651 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2652 * config.h.W32.template: Ditto.
2653 * config.h-vms.template: Ditto.
2654 * config.ami.template: Ditto.
2656 2004-03-04 Paul D. Smith <psmith@gnu.org>
2658 * README.template: Add a note about broken /bin/sh on SunOS
2659 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2661 * misc.c (message, error, fatal): Don't use "..." if we're using
2662 varargs. ansi2knr should handle this but it doesn't work: it
2663 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2664 done. On many systems (SunOS for example) va_dcl is a #define.
2665 So, force the use of the non-"..." version on pre-ANSI compilers.
2667 * maintMakefile (sign-dist): Create some rules to help automate
2668 the new GNU ftp upload method.
2670 2004-02-24 Paul D. Smith <psmith@gnu.org>
2672 * config.h.W32.template: Add HAVE_STDARG_H
2673 * config.h-vms.template: Ditto.
2674 * config.ami.template: Ditto.
2676 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2678 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2679 * build_w32.bat: Remove extra "+".
2681 2004-02-23 Paul D. Smith <psmith@gnu.org>
2683 * make.h: Create an UNUSED macro to mark unused parameters.
2684 * (many): Clean up warnings by applying UNUSED, fixing
2685 signed/unsigned incompatibilities, etc.
2687 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2689 * filedef.h: Name the command_state enumeration.
2690 * file.c (set_command_state): Use the enumeration in the function
2693 * configure.in: Explicitly set SET_MAKE to empty, to disable
2694 MAKE=make even when no make already exists. Fix bug #3823.
2696 2004-02-22 Paul D. Smith <psmith@gnu.org>
2698 * maintMakefile: Perl script to clean up all non-CVS files. Use
2699 it on all the subdirectories for the cvs-clean target.
2701 * main.c (decode_switches): Require non-empty strings for all our
2702 string command-line options. Fixes Debian bug # 164165.
2704 * configure.in: Check for stdarg.h and varargs.h.
2705 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2706 for printing messages.
2707 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2712 A number of patches for OS/2 support from Andreas Buening
2713 <andreas.buening@nexgo.de>:
2715 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2716 disable the SIGCHLD handler.
2717 (reap_children) [OS/2]: Remove special handling of job_rfd.
2718 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2719 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2720 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2721 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2722 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2725 2004-02-21 Paul D. Smith <psmith@gnu.org>
2727 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2728 <mail@kristov.de> reports that if process_begin() fails we don't
2729 handle the error condition correctly in all cases.
2730 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2731 to have a newline on the message.
2733 * job.c (construct_command_argv_internal): Add "test" to UNIX
2734 sh_cmds[]. Fixes Savannah bug # 7606.
2736 2004-02-04 Paul D. Smith <psmith@gnu.org>
2738 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2739 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2740 Hartmut Becker <Hartmut.Becker@hp.com>.
2742 2004-01-21 Paul D. Smith <psmith@gnu.org>
2744 * job.c (load_too_high): Implement an algorithm to control the
2745 "thundering herd" problem when using -l to control job creation
2746 via the load average. The system only recomputes the load once a
2747 second but we can start many jobs in a second. To solve this we
2748 keep track of the number of jobs started in the last second and
2749 apply a weight to try to guess what a correct load would be.
2750 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2751 Also fixes bug #4693.
2752 (reap_children): Decrease the job count for this second.
2753 (start_job_command): Increase the job count for this second.
2755 * read.c (conditional_line): Expand the text after ifn?def before
2756 checking to see if it's a single word. Fixes bug #7257.
2758 2004-01-09 Paul D. Smith <psmith@gnu.org>
2760 * file.c (print_file): Recurse to print all targets in
2761 double-colon rules. Fixes bug #4518, reported (with patch) by
2762 Andrew Chatham <chatham@google.com>.
2764 2004-01-07 Paul D. Smith <psmith@gnu.org>
2766 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2767 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2768 AC_FUNC_SETVBUF_REVERSED.
2770 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2771 (MAKE Variable): Fix Savannah bug #4898.
2773 * job.c (construct_command_argv_internal): Add "!" to the list of
2774 shell escape chars. POSIX sh allows it to appear before a
2775 command, to negate the exit code. Fixes bug #6404.
2777 * implicit.c (pattern_search): When matching an implicit rule,
2778 remember which dependencies have the ignore_mtime flag set.
2779 Original fix provided in Savannah patch #2349, by Benoit
2780 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2782 2003-11-22 Paul D. Smith <psmith@gnu.org>
2784 * README.W32.template (Outputs): Clarification on -j with
2785 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2788 2003-11-02 Paul D. Smith <psmith@gnu.org>
2790 * function.c (func_if): Strip all the trailing whitespace from the
2791 condition, then don't expand it. Fixed bug # 5798.
2793 * expand.c (recursively_expand_for_file): If we're expanding a
2794 variable with no file context, then use the variable's context.
2797 2003-10-21 Paul D. Smith <psmith@gnu.org>
2799 * main.c (log_working_directory): Add newlines to printf()s.
2801 * README.cvs: Add a note to ignore warnings during autoreconf.
2803 * maintMakefile (po_repo): Set a new URL for PO file updates.
2804 (get-config/config.guess get-config/config.sub): Get these files
2805 from the Savannah config project instead of ftp.gnu.org.
2807 2003-10-05 Paul Eggert <eggert@twinsun.com>
2809 * main.c (main): Avoid potential subscript error if environ has
2812 2003-08-22 Paul D. Smith <psmith@gnu.org>
2814 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2815 systems which don't yet implement the C89 standard :-/.
2817 2003-07-18 Paul D. Smith <psmith@gnu.org>
2819 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2820 [WINDOWS32]: Initialize hash.
2822 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2824 * dir.c (read_dirstream): Provide a workaround for broken versions of
2825 the MinGW dirent structure.
2827 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2829 * w32/include/dirent.h: Add __MINGW32__ filter.
2831 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2833 * make.h: Add global declaration of *make_host.
2834 * main.c (print_usage): Remove local declaration of *make_host.
2835 (print_version): Display "This program built for ..." after Copyright
2838 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2840 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2841 execution of "makeinfo --html make.texi".
2843 2003-04-30 Paul D. Smith <psmith@gnu.org>
2845 * build.template: Make some changes to maybe allow this script to
2846 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2848 * README.OS2.template: New file for OS/2 support. Original
2849 contributed by Andreas Buening.
2850 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2853 2003-04-19 Paul D. Smith <psmith@gnu.org>
2855 Fix bug #1405: allow a target to match multiple pattern-specific
2858 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2859 variable.c, where they've always belonged.
2860 * rule.h: Move the prototypes and struct pattern_var as well.
2861 * variable.c (initialize_file_variables): Invoke
2862 lookup_pattern_var() in a loop, until no more matches are found.
2863 If a match is found, create a new variable set for the target's
2864 pattern variables. Then merge the contents of each matching
2865 pattern variable set into the target's pattern variable set.
2866 (lookup_pattern_var): Change this function to be usable
2867 in a loop. It takes a starting position: if NULL, start at the
2868 beginning; if non-NULL, start with the pattern variable after that
2869 position, and return the next matching pattern.
2870 (create_pattern_var): Create a unique instance of
2871 pattern-specific variables for every definition in the makefile.
2872 Don't combine the same pattern together. This allows us to
2873 process the variable handling properly even when the same pattern
2874 is used multiple times.
2875 (parse_variable_definition): New function: break out the parsing
2876 of a variable definition line from try_variable_definition.
2877 (try_variable_definition): Call parse_variable_definition to
2879 (print_variable_data_base): Print out pattern-specific variables.
2880 * variable.h (struct variable): Remember when a variable is
2881 conditional. Also remember its flavor.
2882 (struct pattern_var): Instead of keeping a variable set, we just
2883 keep a single variable for each pattern.
2884 * read.c (record_target_var): Each pattern variable contains only a
2885 single variable, not a set, so create it properly.
2886 * doc/make.texi (Pattern-specific): Document the new behavior.
2888 2003-04-17 Paul D. Smith <psmith@gnu.org>
2890 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2891 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2892 file/directory naming rules for VMS so I can't tell whether this
2895 2003-04-09 Paul D. Smith <psmith@gnu.org>
2897 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2898 DOS-style pathnames: backslash separators and drive specifiers.
2900 2003-03-28 Paul D. Smith <psmith@gnu.org>
2902 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2903 the intermediate flag on all targets. Fixes bug #2515.
2905 2003-03-24 Paul D. Smith <psmith@gnu.org>
2907 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2908 Upgrade to autoconf 2.57 and automake 1.7.3.
2910 * job.c: More OS/2 changes from Andreas Buening.
2912 * file.c (print_file): Fix variable initialization.
2915 * remake.c (notice_finished_file):
2917 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2918 some calls (like readdir()) return NULL in valid situations
2919 without resetting errno. Fixes bug #2846.
2921 2003-02-25 Paul D. Smith <psmith@gnu.org>
2923 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2925 * job.c (_is_unixy_shell) [OS/2]: New function.
2926 Set default shell to /bin/sh.
2927 (reap_children): Close the job_rfd pipe here since we don't use a
2929 (set_child_handler_action_flags): define this to empty on OS/2.
2930 (start_job_command): Close the jobserver pipe and use
2931 child_execute_job() instead of fork/exec.
2932 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2933 rather than exec'ing, then reconfigure stdin/stdout.
2934 (exec_command): Rewrite to use spawn instead of exec. Return the
2937 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2938 in DOS. Handle the TEMP environment variable as in DOS. Don't
2939 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2940 use -j in DOS mode. Use child_execute_job() instead of
2943 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2946 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2947 prototypes that return values.
2949 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2951 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2952 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2954 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2957 2003-02-24 Paul D. Smith <psmith@gnu.org>
2959 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2960 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2961 (child_execute_job) [VMS]: Handle error status properly.
2962 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2964 * function.c (func_shell): Use EINTRLOOP() while reading from the
2965 subshell pipe (Fixes bug #2502).
2966 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2968 * main.c (main): Ditto.
2970 2003-01-30 Paul D. Smith <psmith@gnu.org>
2972 * read.c (eval): eval() was not fully reentrant, because the
2973 collapsed buffer was static. Change it to be an automatic
2974 variable so that eval() can be invoked recursively.
2976 (eval): Apply patch # 1022: fix memory reference error on long
2977 target-specific variable lines.
2978 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2980 * function.c (check_numeric): Combine the is_numeric() function
2981 into this function, since it's only called from one place.
2982 Constify this function. Have it print the incorrect string in the
2983 error message. Fixes bug #2407.
2984 (strip_whitespace): Constify.
2985 (func_if): Constify.
2986 * expand.c (expand_argument): Constify.
2988 2003-01-29 Paul D. Smith <psmith@gnu.org>
2990 Fix bug # 2169, also reported by other people on various systems.
2992 * make.h: Some systems, such as Solaris and PTX, do not fully
2993 implement POSIX-compliant SA_RESTART functionality; important
2994 system calls like stat() and readdir() can still fail with EINTR
2995 even if SA_RESTART has been set on the signal handler. So,
2996 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2997 EINTR for system calls which return -1 or 0 (NULL), respectively,
2999 Also, remove the old atomic_stat()/atomic_readdir() and
3000 HAVE_BROKEN_RESTART handling.
3002 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3004 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3005 * remake.c (touch_file): Ditto.
3007 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3008 * read.c (construct_include_path): Ditto.
3009 * remake.c (name_mtime): Ditto.
3010 * vpath.c (selective_vpath_search): Ditto.
3011 * dir.c (find_directory): Ditto.
3012 (local_stat): Ditto.
3013 (find_directory): Use ENULLLOOP() to wrap opendir().
3014 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3016 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3017 atomic_readdir() handling.
3019 2003-01-22 Paul D. Smith <psmith@gnu.org>
3021 * function.c (func_call): Fix Bug #1744. If we're inside a
3022 recursive invocation of $(call ...), mask any of the outer
3023 invocation's arguments that aren't used by this one, so that this
3024 invocation doesn't "inherit" them accidentally.
3026 2002-12-05 Paul D. Smith <psmith@gnu.org>
3028 * function.c (subst_expand): Valery Khamenia reported a
3029 pathological performance hit when doing substitutions on very
3030 large values with lots of words: turns out we were invoking
3031 strlen() a ridiculous number of times. Instead of having each
3032 call to sindex() call strlen() again, keep track of how much of
3033 the text we've seen and pass the length to sindex().
3035 2002-11-19 Paul D. Smith <psmith@gnu.org>
3037 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3040 2002-11-16 Paul D. Smith <psmith@gnu.org>
3042 * NMakefile.template (OBJS): Add hash.c object file.
3043 * SMakefile.template (srcs): Ditto.
3044 * Makefile.ami (objs): Ditto.
3045 * build_w32.bat: Ditto.
3047 * Makefile.DOS.template: Remove extra dependencies.
3049 2002-10-25 Paul D. Smith <psmith@gnu.org>
3051 * expand.c (install_variable_buffer): New function. Install a new
3052 variable_buffer context and return the previous one.
3053 (restore_variable_buffer): New function. Free the current
3054 variable_buffer context and put a previously saved one back.
3055 * variable.h: Prototypes for {install,restore}_variable_buffer.
3056 * function.c (func_eval): Push a new variable_buffer context
3057 before we eval, then restore the old one when we're done.
3060 * read.c (install_conditionals): New function. Install a new
3061 conditional context and return the previous one.
3062 (restore_conditionals): New function. Free the current
3063 conditional context and put a previously saved one back.
3064 (eval): Use the {install,restore}_conditionals for "include"
3066 (eval_buffer): Use {install,restore}_conditionals to preserve the
3067 present conditional state before we evaluate the buffer.
3070 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3072 (Recursion): Add a variable index entry for CURDIR.
3074 * README.cvs: Update to appropriate versions.
3075 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3076 don't need to copy loadavg.c: automake is smart enough to create
3077 it for me. Still have a bug in automake related to ansi2knr tho.
3079 2002-10-14 Paul D. Smith <psmith@gnu.org>
3081 * remake.c (notice_finished_file): Only touch targets if they have
3082 at least one command (as per POSIX). Resolve Bug #1418.
3084 * *.c: Convert to using ANSI C-style function definitions.
3085 * Makefile.am: Enable the ansi2knr feature of automake.
3086 * configure.in: ditto.
3088 2002-10-13 Paul D. Smith <psmith@gnu.org>
3090 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3091 for automatic variable values like $^, etc. In the case of very
3092 large lists of prerequisites this causes problems. Instead reuse
3093 a static buffer (resizeable) for each variable.
3095 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3096 target-specific variable definitions. Check for it and set an
3098 (record_target_var): Set the export field to v_export if the
3099 "exported" flag is set.
3100 * doc/make.texi (Target-specific): Document the ability to use
3103 * doc/make.texi: Change the name of the section on automatic
3104 variables from "Automatic" to "Automatic Variables". Added text
3105 clarifying the scope of automatic variables.
3107 2002-10-04 Paul D. Smith <psmith@gnu.org>
3109 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3111 (record_files): Ditto.
3113 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3114 the search for the '=' to only within the enclosing parens.
3116 2002-10-03 Paul D. Smith <psmith@gnu.org>
3118 Version 3.80 released.
3120 * dir.c: Change hash functions to use K&R function definition style.
3121 * function.c: Ditto.
3123 * variable.c: Ditto.
3125 Update to automake 1.7.
3127 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3128 (pdf): Remove this target as automake now provides one.
3130 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3132 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3134 * makefile.com: Updates for GNU make 3.80.
3135 * makefile.vms: Ditto.
3137 2002-09-23 Paul D. Smith <psmith@gnu.org>
3139 * read.c (enum make_word_type): Remove w_comment.
3140 (get_next_mword): Don't treat comment characters as special; where
3141 this function is used we will never see a comment (it's stripped
3142 before we get here) and treating comments specially means that
3143 targets like "foo\#bar" aren't handled properly.
3145 2002-09-18 Paul D. Smith <psmith@gnu.org>
3147 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3149 * read.c (eval): Expansion of arguments to export/unexport was
3150 ignoring all arguments after the first one. Change the algorithm
3151 to expand the whole line once, then parse the results.
3153 2002-09-17 Paul D. Smith <psmith@gnu.org>
3155 Fix Bug #940 (plus another bug I found while looking at this):
3157 * read.c (record_target_var): enter_file() will add a new entry if
3158 it's a double-colon target: we don't want to do that in this
3159 situation. Invoke lookup_file() and only enter_file() if it does
3160 not already exist. If the file we get back is a double-colon then
3161 add this variable to the "root" double-colon target.
3163 * variable.c (initialize_file_variables): If this file is a
3164 double-colon target but is not the "root" target, then initialize
3165 the root and make the root's variable list the parent of our
3168 2002-09-13 Paul D. Smith <psmith@gnu.org>
3170 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3172 * hash.c (round_up_2): Get rid of a warning.
3174 2002-09-12 Paul D. Smith <psmith@gnu.org>
3176 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3177 so it doesn't complain about getloadavg.c.
3179 * commands.c (set_file_variables): Make sure we always alloca() at
3180 least 1 character for the value of $? (for '\0').
3182 2002-09-11 Paul D. Smith <psmith@gnu.org>
3184 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3185 macro to use RESULT instead of the incorrect _RESULT_.
3187 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3188 and atomic_readdir(). We need to #include dirent.h to get this to
3190 * misc.c (atomic_readdir): Fix typos.
3192 2002-09-10 Paul D. Smith <psmith@gnu.org>
3194 * read.c (eval): Expand variable lists given to export and
3195 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3196 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3198 * doc/make.texi (Variables/Recursion): Document this.
3199 (Conditional Syntax): And here.
3201 2002-09-09 Paul D. Smith <psmith@gnu.org>
3203 * configure.in: Check for memmove().
3205 2002-09-07 Paul D. Smith <psmith@gnu.org>
3207 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3208 Michael Sterrett <msterret@coat.com> reports that while it has
3209 SA_RESTART, it does not work properly.
3211 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3212 that invokes stat() and loops to do it again if it returns EINTR.
3213 (atomic_readdir): Ditto, with readdir().
3215 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3216 and readdir() to atomic_stat() and atomic_readdir().
3218 2002-09-04 Paul D. Smith <psmith@gnu.org>
3220 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3221 reports that GNU make sometimes doesn't recognize that targets can
3222 be made, when directories can be created as prerequisites. He
3223 reports that changing the order of predicates in the DEP->changed
3224 flag test so that lookup_file() is always performed, solves this
3227 2002-08-08 Paul D. Smith <psmith@gnu.org>
3229 * configure.in: Require a newer version of gettext.
3231 * misc.c (perror_with_name): Translate the format string (for
3232 right-to-left language support).
3233 (pfatal_with_name): Ditto.
3235 * main.c: Create a static array of strings to store the usage
3236 text. This is done to facilitate translations.
3237 (struct command_switch): Remove argdesc and description fields.
3238 (switches): Remove values for obsolete fields.
3239 (print_usage): Print each element of the usage array.
3241 * hash.c: Change function definitions to be K&R style.
3243 2002-08-02 Paul D. Smith <psmith@gnu.org>
3245 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3246 this one because it's too hard to get right. We'll look at it for
3248 * main.c (main): Don't create the .TARGETS variable.
3249 * variable.c (handle_special_var): Don't handle .TARGETS.
3251 2002-08-01 Paul D. Smith <psmith@gnu.org>
3253 * main.c (switches): Add a new option, -B (--always-make). If
3254 specified, make will rebuild all targets that it encounters even
3255 if they don't appear to be out of date.
3256 (always_make_flag): New flag.
3257 * make.h: Extern always_make_flag.
3258 * remake.c (update_file_1): Check always_make_flag; if it's set we
3259 will always rebuild any target we can, even if none of its
3260 prerequisites are newer.
3263 * doc/make.texi (Shell Function): Make it clear that make
3264 variables marked as "export" are not passed to instances of the
3267 Add new introspection variable .VARIABLES and .TARGETS.
3269 * variable.c (handle_special_var): New function. If the variable
3270 reference passed in is "special" (.VARIABLES or .TARGETS),
3271 calculate the new value if necessary. .VARIABLES is handled here:
3272 walk through the hash of defined variables and construct a value
3273 which is a list of the names. .TARGETS is handled by
3274 build_target_list().
3275 (lookup_variable): Invoke handle_special_var().
3276 * file.c (build_target_list): Walk through the hask of known files
3277 and construct a list of the names of all the ones marked as
3279 * main.c (main): Initialize them to empty (and as simple variables).
3280 * doc/make.texi (Special Variables): Document them.
3281 * NEWS: Mention them.
3283 * variable.h (struct variable): Add a new flag "exportable" which
3284 is true if the variable name is valid for export.
3285 * variable.c (define_variable_in_set): Set "exportable" when a new
3286 variable is defined.
3287 (target_environment): Use the "exportable" flag instead of
3288 re-checking the name here... an efficiency improvement.
3290 2002-07-31 Paul D. Smith <psmith@gnu.org>
3292 * config.h-vms.template: Updates to build on VMS. Thanks to
3293 Brian_Benning@aksteel.com for helping verify the build.
3294 * makefile.com: Build the new hash.c file.
3295 * hash.h: Use strcpmi(), not stricmp(), in the
3296 HAVE_CASE_INSENSITIVE_FS case.
3298 2002-07-30 Paul D. Smith <psmith@gnu.org>
3300 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3301 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3302 Reported by <Brian_Benning@aksteel.com>.
3304 2002-07-10 Paul D. Smith <psmith@gnu.org>
3306 * variable.c (pop_variable_scope): Remove variable made unused by
3307 new hash infrastructure.
3308 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3309 comparisons as well as name comparisons.
3310 * variable.h: Add a prototype for new hash_init_function_table().
3311 * file.c (lookup_file): Remove variables made unused by new hash
3313 * dir.c (directory_contents_hash_2): Missing return of hash value.
3314 (dir_contents_file_exists_p): Remove variables made unused by new
3315 hash infrastructure.
3318 Installed Greg McGary's integration of the hash functions from the
3319 GNU id-utils package:
3321 2002-07-10 Greg McGary <greg@mcgary.org>
3323 * scripts/functions/filter-out: Add literals to to the
3324 pattern space in order to add complexity, and trigger
3325 use of an internal hash table. Fix documentation strings.
3326 * scripts/targets/INTERMEDIATE: Reverse order of files
3327 passed to expected `rm' command.
3329 2002-07-10 Greg McGary <greg@mcgary.org>

3421 2002-07-10 Paul D. Smith <psmith@gnu.org>
3423 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3424 prerequisite list. A real SysV make will expand the entire
3425 prerequisites list _twice_: we don't do that as it's a big
3426 backward-compatibility problem. We only replace those specific
3429 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3430 references left in the list of prerequisites. Check for .POSIX as
3431 we record targets, so we can disable non-POSIX behavior while
3432 reading makefiles as well as running them.
3433 (eval): Check the prerequisite list to see if we have anything
3434 that looks like a SysV prerequisite variable reference.
3436 2002-07-09 Paul D. Smith <psmith@gnu.org>
3438 * doc/make.texi (Prerequisite Types): Add a new section describing
3439 order-only prerequisites.
3441 * read.c (uniquize_deps): If we have the same file as both a
3442 normal and order-only prereq, get rid of the order-only prereq,
3443 since the normal one supersedes it.
3445 2002-07-08 Paul D. Smith <psmith@gnu.org>
3447 * AUTHORS: Added Greg McGary to the AUTHORS file.
3448 * NEWS: Blurbed order-only prerequisites.
3449 * file.c (print_file): Show order-only deps properly when printing
3452 * maintMakefile: Add "update" targets for wget'ing the latest
3453 versions of various external files. Taken from Makefile.maint in
3456 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3457 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3459 2002-07-07 Paul D. Smith <psmith@gnu.org>
3461 * po/*.po: Remove. We'll use wget to retrieve them at release
3464 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3465 rather than a shell you get an exception. Make sure we look up
3466 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3468 * remake.c (notice_finished_file): Fix handling of -t flag.
3469 Patch provided by Henning Makholm <henning@makholm.net>.
3471 * implicit.c (pattern_search): Some systems apparently run short
3472 of stack space, and using alloca() in this function caused an
3473 overrun. I modified it to use xmalloc() on the two variables
3474 which seemed like they might get large. Fixes Bug #476.
3476 * main.c (print_version): Update copyright notice to conform with
3478 (print_usage): Update help output.
3480 * function.c (func_eval): Create a new make function, $(eval
3481 ...). Expand the arguments, put them into a buffer, then invoke
3482 eval_buffer() on the resulting string.
3483 (func_quote): Create a new function, $(quote VARNAME). Inserts
3484 the value of the variable VARNAME without expanding it any
3487 * read.c (struct ebuffer): Change the linebuffer structure to an
3488 "eval buffer", which can be either a file or a buffer.
3489 (eval_makefile): Move the code in the old read_makefile() which
3490 located a makefile into here: create a struct ebuffer with that
3491 information. Have it invoke the new function eval() with that
3493 (eval_buffer): Create a new function that creates a struct ebuffer
3494 that holds a string buffer instead of a file. Have it invoke
3495 eval() with that ebuffer.
3496 (eval): New function that contains the guts of the old
3497 read_makefile() function: this function parses makefiles. Obtains
3498 data to parse from the provided ebuffer. Some modifications to
3499 make the flow of the function cleaner and clearer. Still could
3500 use some work here...
3501 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3502 contents of the define/endef variable from the ebuffer.
3503 (readstring): Read the next line from a string-style ebuffer.
3504 (readline): Read the next line from an ebuffer. If it's a string
3505 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3508 * dep.h (eval_buffer): Prototype eval_buffer();
3510 * variable.c (do_variable_definition): Make sure that all
3511 non-target-specific variables are registered in the global set.
3512 If we're invoked from an $(eval ...) we might be inside a $(call
3513 ...) or other function which has pushed a variable scope; we still
3514 want to define our variables from evaluated makefile code in the
3517 2002-07-03 Greg McGary <greg@mcgary.org>
3519 * dep.h (struct dep) [ignore_mtime]: New member.
3520 [changed]: convert to a bitfield.
3521 * implicit.c (pattern_search): Zero ignore_mtime.
3522 * main.c (main, handle_non_switch_argument): Likewise.
3523 * rule.c (convert_suffix_rule): Likewise.
3524 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3525 (read_makefile): Parse '|' in prerequisite list.
3526 (uniquize_deps): Consider ignore_mtime when comparing deps.
3527 * remake.c (update_file_1, check_dep): Don't force remake for
3528 dependencies that have d->ignore_mtime.
3529 * commands.c (FILE_LIST_SEPARATOR): New constant.
3530 (set_file_variables): Don't include a
3531 prerequisite in $+, $^ or $? if d->ignore_mtime.
3534 2002-06-18 Paul D. Smith <psmith@gnu.org>
3536 * make.texinfo: Updates for next revision. New date/rev/etc.
3537 Recreate all Info menus. Change license on the manual to the GNU
3538 Free Documentation License. A number of typos.
3539 (Variables Simplify): Don't use "-" before it's defined.
3540 (Automatic Prerequisites): Rewrite the target example to work
3541 properly if the compile fails. Remove incorrect comments about
3542 how "set -e" behaves.
3543 (Text Functions): Move the "word", "wordlist", "words", and
3544 "firstword" functions here, from "File Name Functions".
3545 * make-stds.texi: Update from latest GNU version.
3546 * fdl.texi: (created) Import the latest GNU version.
3548 2002-06-06 Paul D. Smith <psmith@gnu.org>
3550 * variable.c (do_variable_definition): New function: extract the
3551 part of try_variable_definition() that actually sets the value
3552 into a separate function.
3553 (try_variable_definition): Call do_variable_definition() after
3554 parsing the variable definition string.
3555 (define_variable_in_set): Make the name argument const.
3557 * variable.h (enum variable_flavor): Make public.
3558 (do_variable_definition): Create prototype.
3560 * read.c (read_all_makefiles): Create a new built-in variable,
3562 (read_makefile): Add each makefile read in to this variable value.
3564 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3566 * Makefile.DOS.template: Tweak according to changes in the
3567 distribution. Add back the dependencies of *.o files.
3569 * configh.dos.template: Synchronize with config.h.in.
3571 2002-05-09 Paul D. Smith <psmith@gnu.org>
3573 * file.c (file_timestamp_now): Use K&R function declaration.
3575 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3576 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3577 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3578 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3579 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3580 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3581 nlist.n_name is a pointer rather than an array.
3583 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3584 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3585 * configure.in: Use it instead of the old version.
3587 * main.c (main): Prefer setvbuf() to setlinebuf().
3589 2002-05-08 Paul D. Smith <psmith@gnu.org>
3591 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3592 (loadavg_LDADD): Ditto.
3594 2002-04-29 Paul D. Smith <psmith@gnu.org>
3596 * expand.c (recursively_expand_for_file): Rename
3597 recursively_expand() to recursively_expand_for_file() and provide
3598 an extra argument, struct file. If the argument is provided, set
3599 the variable scope to that of the file before expanding.
3600 * variable.h (recursively_expand): Make this a macro that invokes
3601 recursively_expand_for_file() with a NULL file pointer.
3602 * variable.c (target_environment): Call the renamed function and
3603 provide the current file context.
3604 Fixes Debian bug #144306.
3606 2002-04-28 Paul D. Smith <psmith@gnu.org>
3608 Allow $(call ...) user-defined variables to be self-referencing
3609 without throwing an error. Allows implementation of transitive
3610 closures, among other possibly useful things.
3611 Requested by: Philip Guenther <guenther@sendmail.com>
3613 * variable.h (struct variable): Add a new field: exp_count, and
3614 new macros to hold its size and maximum value.
3615 (warn_undefined): Make this a macro.
3616 * variable.c (define_variable_in_set): Initialize it.
3617 * expand.c (recursively_expand): If we detect recursive expansion
3618 of a variable, check the exp_count field. If it's greater than 0
3619 allow the recursion and decrement the count.
3620 (warn_undefined): Remove this (now a macro in variable.h).
3621 * function.c (func_call): Before we expand the user-defined
3622 function, modify its exp_count field to contain the maximum
3623 number of recursive calls we'll allow. After the call, reset it
3626 2002-04-21 Paul D. Smith <psmith@gnu.org>
3628 Modified to use latest autoconf (2.53), automake (1.6.1), and
3629 gettext (0.11.1). We're using gettext's new "external" support,
3630 to avoid including libintl source with GNU make.
3632 * README.cvs: New file. Explain how to build GNU make from CVS.
3634 * configure.in: Modify checking for the system glob library.
3635 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3636 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3637 etc. will manage it correctly). Set an automake conditional
3638 USE_LOCAL_GLOB to decide whether to compile the glob library.
3640 * getloadavg.c (main): Include make.h in the "TEST" program to
3643 * Makefile.am: Remove special rules for loadavg. Replace them
3644 with Automake capabilities for building extra programs.
3646 * signame.c: This file does nothing if the system provide
3647 strsignal(). If not, it implements strsignal(). If the system
3648 doesn't define sys_siglist, then we make our own; otherwise we use
3650 * signame.h: Removed.
3652 * main.c (main): No need to invoke signame_init(). Update copyright.
3654 * ABOUT-NLS: Removed.
3655 * gettext.c: Removed.
3656 * gettext.h: Get a simplified copy from the gettext package.
3658 * i18n/*.po: Moved to po/.
3661 * config/*: Created. Contains package configuration helper files.
3662 * config.guess, config.sub: Moved to config directory.
3664 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3665 Rework to use new-style autoconf features. Use the "external"
3666 mode for gettext. Make the build.sh config file conditional on
3667 whether build.sh.in exists, to avoid autoconf errors.
3668 * acinclude.m4: Removed almost all macros as being obsolete.
3669 Rewrote remaining macros to use AC_DEFINE.
3670 * acconfig.h: Removed.
3672 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3673 conditional to handle customs support. Remove special handling
3676 2002-04-20 Paul D. Smith <psmith@gnu.org>
3678 * function.c (func_call): Don't mark the argument variables $1,
3679 etc. as recursive. They've already been fully expanded so
3680 there's no need to do it again, and doing so strips escaped $'s.
3681 Reported by Sebastian Glita <glseba@yahoo.com>.
3683 * remake.c (notice_finished_file): Walk through double-colon
3684 entries via the prev field, not the next field!
3685 Reported by Greg McGary <greg@mcgary.org>.
3687 * main.c (main): If the user specifies -q and asks for a specific
3688 target which is a makefile, we got an assert. In that case it
3689 turns out we should continue normally instead.
3691 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3693 * i18n/he.po: Installed a new translation.
3695 2002-01-07 Paul D. Smith <psmith@gnu.org>
3697 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3699 2001-12-04 Paul D. Smith <psmith@gnu.org>
3701 * i18n/ja.po: Installed an updated translation.
3703 2001-09-06 Paul Eggert <eggert@twinsun.com>
3705 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3706 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3708 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3710 (main): Get rid of any avoidable limit on stack size.
3712 2001-09-04 Paul D. Smith <psmith@gnu.org>
3714 * i18n/da.po: Installed an updated translation.
3716 2001-08-03 Paul D. Smith <psmith@gnu.org>
3718 * i18n/fr.po: Installed an updated translation.
3719 Resolves Debian bug #106720.
3721 2001-06-13 Paul D. Smith <psmith@gnu.org>
3723 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3726 2001-06-11 Paul D. Smith <psmith@gnu.org>
3728 * i18n/ko.po: Installed a new translation.
3730 2001-05-06 Paul D. Smith <psmith@gnu.org>
3732 Modify the EINTR handling.
3734 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3735 the way in which we manage the file descriptor/signal handler race
3736 trap to be more efficient.
3738 2001-05-06 Paul Eggert <eggert@twinsun.com>
3740 Restart almost all system calls that are interrupted, instead
3741 of worrying about EINTR. The lone exception is the read() for
3744 * configure.in (HAVE_SA_RESTART): New macro.
3745 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3746 * main.c (main): Use SA_RESTART instead of the old,
3747 nonstandard SA_INTERRUPT.
3749 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3750 * main.c (bsd_signal): New function or macro,
3751 if the implementation doesn't supply it.
3752 (The bsd_signal function will be in POSIX 1003.1-200x.)
3753 (HANDLESIG): Remove.
3754 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3756 * make.h (EINTR_SET): Remove.
3757 (SA_RESTART): New macro.
3759 * arscan.c (ar_member_touch): Don't worry about EINTR.
3760 * function.c (func_shell): Likewise.
3761 * job.c (reap_children, free_child, new_job): Likewise.
3762 * main.c (main): Likewise.
3763 * remake.c (touch_file, name_mtime): Likewise.
3765 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3766 if fstat failed with errno!=EINTR, the error was ignored.
3768 * job.c (set_child_handler_action_flags): New function.
3769 (new_job): Use it to temporarily clear the SIGCHLD action flags
3770 while reading the token.
3772 2001-05-02 Paul D. Smith <psmith@gnu.org>
3774 * job.c (start_job_command): Don't add define/endef per-line flags
3775 to the top-level flags setting.
3777 2001-04-03 Paul D. Smith <psmith@gnu.org>
3779 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3780 bit on error, so check for odd return values, not non-0 return
3782 (VMS_get_member_info): Calculate the timezone differences correctly.
3783 Reported by John Fowler <jfowler@nyx.net>.
3786 2001-03-14 Paul D. Smith <psmith@gnu.org>
3788 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3789 value before invoking define_variable().
3790 Reported by John Fowler <jfowler@nyx.net>.
3792 2001-02-07 Paul D. Smith <psmith@gnu.org>
3794 * read.c (record_target_var): If we reset the variable due to a
3795 command-line variable setting overriding it, turn off the "append"
3798 2001-01-17 Paul D. Smith <psmith@gnu.org>
3800 * variable.c (lookup_variable) [VMS]: When getting values from the
3801 environment, allocate enough space for the _value_ plus escapes,
3802 not enough space for the name plus escapes :-/.
3803 Reported by John Fowler <jfowler@nyx.net>.
3805 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3806 warnings that make generates, so it doesn't look like an error.
3807 Reported by Karl Berry <karl@gnu.org>.
3810 Fix for PR/2020: Rework appended target-specific variables. I'm
3811 fairly confident this algorithm is finally correct.
3813 * expand.c (allocated_variable_append): Rewrite. Instead of
3814 expanding each appended variable then adding all the expanded
3815 strings together, we append all the unexpanded values going up
3816 through the variable set contexts, then expand the final result.
3817 This behaves just like non-target-specific appended variable
3818 values, while the old way didn't in various corner cases.
3819 (variable_append): New function: recursively append the unexpanded
3820 value of a variable, walking from the outermost variable scope to
3822 * variable.c (lookup_variable): Remove the code that looked up the
3823 variable set list if the found variable was "append". We don't
3825 (lookup_variable_in_set): Make this non-static so we can use it
3827 (try_variable_definition): Use lookup_variable_in_set() rather
3828 than faking out current_variable_set_list by hand (cleanup).
3829 * variable.h: Add a prototype for the now non-static
3830 lookup_variable_in_set().
3832 2000-11-17 Paul D. Smith <psmith@gnu.org>
3834 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3835 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3836 before throwing a fit.
3838 2000-11-17 Paul D. Smith <psmith@gnu.org>
3840 * read.c (readline): CRLF calculations had a hole, if you hit the
3841 buffer grow scenario just right. Reworked the algorithm to avoid
3842 the need for len or lastlen at all. Problem description with
3843 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3845 2000-10-24 Paul D. Smith <psmith@gnu.org>
3847 * gettext.c (SWAP): Declare this with the prototype, otherwise
3848 some systems don't work (non-32-bit? Reported for Cray T3E).
3849 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3851 2000-10-05 Paul D. Smith <psmith@gnu.org>
3853 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3854 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3856 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3858 2000-09-22 Paul D. Smith <psmith@gnu.org>
3860 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3861 parts of the real gettext.h here, and we expect to really include
3862 the real gettext.h later. If we keep this #define, it's ignored.
3864 2000-09-21 Paul D. Smith <psmith@gnu.org>
3866 * main.c (log_working_directory): Rework the text to use complete
3867 sentences, to make life simpler for the translators.
3869 2000-08-29 Paul D. Smith <psmith@gnu.org>
3871 * file.c (remove_intermediates): Print a debug message before we
3872 remove intermediate files, so the user (if she uses -d) knows
3875 2000-08-21 Paul D. Smith <psmith@gnu.org>
3877 * variable.c (try_variable_definition): Change how we handle
3878 target-specific append variable defns: instead of just setting the
3879 value, expand it as an append _but_ only within the current
3880 target's context. Otherwise we lose all but the last value if the
3881 variable is appended more than once within the current target
3882 context. Fixes PR/1831.
3884 2000-08-16 Paul D. Smith <psmith@gnu.org>
3886 * function.c (func_shell): Nul-terminate the buffer before
3887 printing an exec error message (just in case it's not!).
3888 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3890 2000-07-25 Paul D. Smith <psmith@gnu.org>
3892 * job.c (construct_command_argv_internal): Add "~" to the list of
3893 sh_chars[] which disallow optimizing out the shell call.
3895 2000-07-23 Paul Eggert <eggert@twinsun.com>
3897 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3898 supersedes --disable-nsec-timestamps.
3899 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3900 * README: Remove --disable-nsec-timestamps.
3902 * filedef.h (struct file.low_resolution_time): New member.
3903 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3904 * remake.c (update_file_1):
3905 Avoid spurious rebuilds due to low resolution time stamps,
3906 generalizing the earlier code that applied only to archive members.
3907 (f_mtime): Archive members always have low resolution time stamps.
3909 * configure.in: Remove --disable-nsec-timestamps, as this has
3910 been superseded by .LOW_RESOLUTION_TIME.
3912 2000-07-23 Paul Eggert <eggert@twinsun.com>
3914 * configure.in (enable_nsec_timestamps): Renamed from
3915 make_cv_nsec_timestamps, since enable/disable options
3916 shouldn't be cached.
3918 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3919 and Paul Eggert <eggert@twinsun.com>
3921 * file.c (file_timestamp_now):
3922 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3923 so that clock_gettime is not linked unless needed.
3925 * filedef.h (FILE_TIMESTAMP_HI_RES):
3926 Remove definition; "configure" now does this.
3928 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3929 to before high resolution file timestamp check,
3930 since that check now uses uintmax_t.
3931 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3932 high resolution file timestamps.
3933 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3934 so that we don't link in clock_gettime unnecessarily.
3936 2000-07-17 Paul D. Smith <psmith@gnu.org>
3938 * i18n/ja.po: New version of the translation file.
3940 2000-07-07 Paul D. Smith <psmith@gnu.org>
3942 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3943 the offset calculation.
3944 (name_mtime): Replace EINTR test with EINTR_SET macro.
3946 2000-07-07 Paul Eggert <eggert@twinsun.com>
3950 * remake.c (update_file_1):
3951 Avoid spurious rebuilds of archive members due to their
3952 timestamp resolution being only one second.
3953 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3954 the clock's resolution being lower than file timestamps'.
3955 When warning about future timestamps, report only the discrepancy,
3956 not the absolute value of the timestamp and the current time.
3958 * file.c (file_timestamp_now): New arg RESOLUTION.
3959 * filedef.h (file_timestamp_now): Likewise.
3960 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3962 2000-07-05 Paul D. Smith <psmith@gnu.org>
3964 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3965 to listp. Fixes PR/1793.
3967 2000-06-26 Paul Eggert <eggert@twinsun.com>
3969 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3971 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3973 * remake.c (f_mtime): Remove unused var memtime.
3975 2000-06-25 Martin Buchholz <martin@xemacs.org>
3977 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3978 Ran spell-check on make.texinfo.
3980 2000-06-23 Paul D. Smith <psmith@gnu.org>
3982 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3983 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3984 * make.h: Define these macros.
3986 * Version 3.79.1 released.
3988 * configure.in: Add a new option, --disable-nsec-timestamps, to
3989 avoid using sub-second timestamps on systems that support it. It
3990 can lead to problems, e.g. if your makefile relies on "cp -p".
3991 * README.template: Document the issue with "cp -p".
3993 * config.guess, config.sub: Updated.
