97 * read.c (parse_file_seq): All archive groups must end with ')' as
98 the LAST character in a word. If there is no word ending in ')'

101 2010-07-01 Paul Smith <psmith@gnu.org>
103 * main.c (main): Append optional features using separate calls.

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

270 * filedef.h (file):Add the NO_DIAG bitfield.
272 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,

319 2009-09-27 Paul Smith <psmith@gnu.org>
321 * doc/make.texi (Double-Colon): Mention that pattern rules with
322 double-colons have a different meaning. Savannah bug #27497.
324 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
326 * configh.dos.template: Remove unconditional definition of
327 SYS_SIGLIST_DECLARED.
328 Include <sys/version.h> because ports of GCC 4.3.0 and later no
329 longer include it, so macros like __DJGPP_MINOR__ are no longer
330 defined automatically.
332 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
333 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
334 instead of using the hardcoded ones.
335 (SUBDIRS): doc subdir added.
336 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
337 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
338 create html formated docs. texi2html may not be ported to DOS.
339 (make.info, make.dvi, make.ps, make.html): Make targets depend on
341 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
342 -I switch to look in ./ instead of ./doc.
343 (html): Target depend on html-recursive instead of make_1.html.
344 (make_1.html): Removed.
345 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
346 (all-recursive): Allow for more than one subdir in the build
348 (mostlyclean-recursive, clean-recursive, distclean-recursive)
349 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
350 (tags-recursive): Allow for more than one subdir in the build
352 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
353 targets. Enter into doc/ to produce the targets.
354 (all-am): $(INFO_DEPS) replaced by info.
356 2009-09-26 Paul Smith <psmith@gnu.org>
358 * read.c (record_files): Use free_ns() to free struct nameseq.
361 * rule.c (freerule): Use free_dep_chain().
363 * read.c (record_files): Free FILENAMES chain for implicit rules.
364 (eval): Static pattern targets go into the string cache.
366 * function.c (string_glob): Free NAME in the nameseq chain.
368 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
370 * implicit.c (pattern_search): Terminate early if we haven't
371 found any rules to try (performance improvement).
373 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
375 * implicit.c (pattern_search): Merge three parallel arrays,
376 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
377 of struct TRYRULE. In the old version the latter two arrays
378 had insufficient length.
380 2009-09-24 Paul Smith <psmith@gnu.org>
382 * implicit.c (pattern_search): Add back support for order-only
383 prerequisites for secondary expansion implicit rules, that were
384 accidentally dropped. If we find a "|", enable order-only mode
385 and set IGNORE_MTIME on all deps that are seen afterward.
386 (pattern_search): Fix memory leaks: for intermediate files where
387 we've already set the file variable and pattern variable sets, be
388 sure to either save or free them as appropriate.
390 2009-09-23 Paul Smith <psmith@gnu.org>
392 Rework the way secondary expansion is stored, for efficiency.
393 This changes secondary expansion so that ONLY WHEN we know we have
394 a possibility of needing secondary expansion, do we defer the
395 secondary expansion. This means more parsing the deps but we use
396 a lot less memory (due to the strcache). Also, this fixes
399 * read.c (eval): Don't parse the dep string here anymore.
400 (record_files): Take the dep argument as an unparsed string. If
401 secondary expansion is enabled AND the prereq string has a '$' in
402 it, then set NEED_2ND_EXPANSION and keep the entire string.
403 Otherwise, parse the dep string here to construct the dep list
404 with the names in the strcache.
406 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
407 duplicate the name string (others are in the strcache).
409 * implicit.c: Remove struct idep and free_idep_chain(): unused.
410 (struct patdeps): New structure to store prereq information.
411 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
412 which prerequisites need expansion, and expand only those.
414 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
415 and enter_prereqs(). split_prereqs() takes a fully-expanded string
416 and splits it into a DEP list, handling order-only prereqs.
417 (enter_prereqs): This function enters a list of DEPs into the file
418 database. If there's a stem defined, expand any pattern chars.
419 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
420 set. Use the above functions.
421 (snap_deps): Only perform second expansion on prereqs that need it,
422 as defined by the NEED_2ND_EXPANSION flag.
423 (print_prereqs): New function to print the prereqs
424 (print_file): Call print_prereqs() rather than print inline.
426 * hash.h (STRING_COMPARE): Take advantage of strcache() by
428 (STRING_N_COMPARE): Ditto.
429 (ISTRING_COMPARE): Ditto.
431 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
432 (parse_file_seq): Return void*
433 * read.c (parse_file_seq): Return void*.
434 (eval): Invoke macroized version of parse_file_seq()
435 * default.c (set_default_suffixes): Ditto.
436 * file.c (split_prereqs): Ditto.
437 * function.c (string_glob): Ditto.
438 * main.c (main): Ditto.
439 * rule.c (install_pattern_rule): Ditto.
441 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
443 2009-09-16 Paul Smith <psmith@gnu.org>
445 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
447 * dep.h: Create alloc_dep() / free_dep() macros.
449 * implicit.c (pattern_search): Take advantage of the new
450 parse_file_seq() to add the directory prefix to each prereq.
452 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
453 all. Avoid reversing chains. Support adding prefixes.
454 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
455 cached/non-cached results.
456 (eval): Remove multi_glob() & invoke new parse_file_seq().
457 * rule.c (install_pattern_rule): Ditto.
458 * main.c (main): Ditto.
459 * implicit.c (pattern_search): Ditto.
460 * function.c (string_glob): Ditto.
461 * file.c (parse_prereqs): Ditto.
462 * default.c (set_default_suffixes): Ditto.
464 * variable.c (parse_variable_definition): Don't run off the end of
465 the string if it ends in whitespace (found with valgrind).
467 * commands.c (set_file_variables): Keep space for all targets in
468 $? if -B is given (found with valgrind).
470 2009-09-15 Paul Smith <psmith@gnu.org>
472 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
473 (xcalloc): Add new function.
474 * make.h: New declarations.
476 * ar.c (ar_glob_match): New calling method for concat().
477 * main.c (main): Ditto.
478 (decode_env_switches): Ditto.
479 * read.c (eval_makefile): Ditto.
480 (tilde_expand): Ditto.
481 (parse_file_seq): Ditto.
482 * variable.c (target_environment): Ditto.
483 (sync_Path_environment): Ditto.
485 * ar.c (ar_glob_match): Use xcalloc().
486 * dir.c (file_impossible): Ditto.
487 * file.c (enter_file): Ditto.
488 * job.c (new_job): Ditto.
489 * read.c (parse_file_seq): Ditto.
490 * vmsfunctions.c (opendir): Ditto.
492 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
494 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
495 inside the loop that looks up environment for PATH.
497 2009-08-31 Eli Zaretskii <eliz@gnu.org>

505 before looping through them. Fixes Savannah bug #21824.
507 * doc/make.texi (Wildcard Examples): Clarify when objects is
508 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
509 (Include): Clarify the behavior of -include.
510 Fixes Savannah bug #18963.
512 2009-08-01 Paul Smith <psmith@gnu.org>
514 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
515 etc. come on the command line. Fixes Savannah bug #27093.
517 * expand.c (expand_argument): If the argument is large enough use
518 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
520 * variable.c (do_variable_definition): Avoid using alloca() to
521 hold values, which can be large. Fixes Savannah bug #23960.
523 * job.c (new_job): Use memmove() instead of strcpy() since both
524 pointers are in the same memory block. Fixes Savannah bug #27148.
525 Patch by Petr Machata.
527 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
529 * job.c (construct_command_argv_internal): Add "ulimit" and
530 "unset" to the sh_cmds for Unixy shells.
532 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
534 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
535 that set make_cv_sys_gnu_glob, so they are also correctly set
536 when the cache has been populated before.
538 2009-07-04 Eli Zaretskii <eliz@gnu.org>
540 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
541 exist, as realpath(3) does where it's supported.
543 2006-07-04 Eli Zaretskii <eliz@gnu.org>
545 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
546 (abspath): Support systems that define HAVE_DOS_PATHS (have
547 drive letters in their file names). Use IS_PATHSEP instead of a
548 literal '/' comparison. Fixes Savannah bug #26886.
550 2009-06-14 Paul Smith <psmith@gnu.org>
552 * remake.c (update_file_1): Remember the original file we marked
553 as updating, so we can clear that flag again. If we find a target
554 via vpath, FILE might change.
555 (check_dep): Ditto. Fixes Savannah bug #13529.
556 Patch by Reid Madsen <reid.madsen@tek.com>.
558 2009-06-13 Paul Smith <psmith@gnu.org>
560 * doc/make.texi (MAKEFILES Variable): Be explicit that files
561 included by MAKEFILES cannot give default goals.
562 * read.c (eval): If set_default is not set, pass the no-default-goal
563 value when we read included makefiles. Fixes Savannah bug #13401.
565 * ar.c (ar_name): Ensure that targets with empty parens aren't
566 considered archive member references: archive members must have a
567 non-empty "member" string. Fixes Savannah bug #18435.
569 * function.c (string_glob): Rely on multi_glob() to determine
570 whether files exist or not. Remove call to file_exists_p() which
571 is not always correct. Fixes Savannah bug #21231.
572 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
573 then only files that really exist will be returned.
574 * dep.h: Add new argument to multi_glob().
575 * rule.c (install_pattern_rule): Ditto.
576 * read.c (eval): Ditto.
577 * main.c (main): Ditto.
578 * implicit.c (pattern_search): Ditto.
579 * file.c (parse_prereqs): Ditto.
580 * default.c (set_default_suffixes): Ditto.
582 2009-06-09 Paul Smith <psmith@gnu.org>
584 * commands.c (set_file_variables): If always_make_flag is set,
585 always add the prereq to $?. Fixes Savannah bug #17825.
587 * remake.c (update_file_1): When rebuilding deps of FILE, also try
588 to rebuild the deps of all the also_make targets for that file.
589 Fixes Savannah bug #19108.
591 * implicit.c (pattern_search): Undo test for is_target, added by
592 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
593 Rule Search Algorithm". Fixes Savannah bug #17752.
595 * main.c (clean_jobserver): Clear the jobserver_fds options and
596 set job_slots to the default when we clean up.
597 (define_makeflags): Return the new MAKEFLAGS value.
598 (main): Reset MAKEFLAGS in the environment when we re-exec.
599 Fixes Savannah bug #18124.
601 2009-06-08 Paul Smith <psmith@gnu.org>
603 * read.c (eval): Collapse continuations post-semicolon on target-
604 specific variables. Fixes Savannah bug #17521.
606 2009-06-07 Paul Smith <psmith@gnu.org>
608 * job.c (reap_children): For older systems without waitpid() (are
609 there any of these left?) run wait(2) inside EINTRLOOP to handle
610 EINTR errors. Fixes Savannah bug #16401.
612 * (various): Debug message cleanup. Fixes Savannah bug #16469.
614 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
616 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
617 not the end, to catch second expansion $(eval ...) defining new
618 target/prereq relationships during snap_deps.
619 Fixes Savannah bug #24622.
621 * read.c (record_files): The second-expansion "f->updating" hack
622 was not completely correct: if assumed that the target with
623 commands always had prerequisites; if one didn't then the ordering
624 was messed up. Fixed for now to use f->updating to decide whether
625 to preserve the last element in the deps list... but this whole
626 area of constructing and reversing the deps list is too confusing
627 and needs to be reworked. Fixes Savannah bug #21198.
629 2009-06-06 Paul Smith <psmith@gnu.org>
631 * hash.c (hash_insert): Remove useless test for NULL.
632 Fixes Savannah bug #21823.
634 * make.h: Move SET_STACK_SIZE determination to make.h.
635 * main.c (main): New global variable, STACK_LIMIT, holds the
636 original stack limit when make was started.
637 * job.c (start_job_command): Reset the stack limit, if we changed it.
638 Fixes Savannah bug #22010.
640 * remake.c (check_dep): Only set the target's state to not-started
641 if it's not already running. Found this while testing -j10 builds
642 of glibc: various targets were being rebuilt multiple times.
643 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
646 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
647 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
650 2009-06-04 Paul Smith <psmith@gnu.org>
652 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
654 * maintMakefile: Modify access of config and gnulib Savannah
655 modules to use GIT instead of CVS.
657 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
658 Fixes Savannah bug #24655.
660 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
661 this can happen during some invocations of $(eval ...) for example.
662 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
664 2009-06-02 Paul Smith <psmith@gnu.org>
666 * configure.in: Check for fileno()
667 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
668 for the makefile file so invocations of $(shell ...) don't inherit it.
669 Fixes Savannah bug #24277.
671 2009-06-01 Paul Smith <psmith@gnu.org>
673 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
674 expansion was handled incorrectly. Rework the default goal
675 handling to save the variable only. Remove default_goal_file and
677 * read.c (eval): Check default_goal_var, not default_goal_name.
678 * read.c (record_target_var): Don't check default_goal_file here.
680 2009-05-31 Paul Smith <psmith@gnu.org>
682 * main.c (main): Expand the .DEFAULT_GOAL variable before using
683 it, and if the multi_glob() returns nothing (say it expanded to
684 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
686 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
687 $(and ..) to the reference. Fixes Savannah bug #25694.
689 * make.1: Be clear that some recipes will be executed even with -n.
690 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
692 * doc/make.texi (Override Directive): Make more clear how
693 overrides and appends interact.
694 Elucidates part of Savannah bug #26207.
696 * read.c (record_target_var): Don't reset the origin on
697 target-specific variables; try_variable_definition() will handle
698 this correctly. Fixes Savannah bug #26207.
700 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
701 Fixes Savannah bug #25712.
703 * implicit.c (pattern_search): Keep a pointer to the beginning of
704 the filename and save that instead of the constructed pointer.
705 Fixes Savannah bug #26593.
706 Patch by Mark Seaborn <mrs@mythic-beasts.com>
708 2009-05-30 Paul Smith <psmith@gnu.org>
710 * doc/make.texi (Multi-Line): Add a description of the new abilities
711 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
712 "command sequence" vs. "recipe" syntax.
713 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
714 after a define, to create variables with those flavors.
716 2009-05-25 Paul Smith <psmith@gnu.org>
718 Reworked the parser for variable assignments to allow multiple
719 modifiers, and in any order. Also allows variable and
720 prerequisites to be modifier names ('export', 'private', etc.)
722 * NEWS: Add notes about user-visible changes.
724 * read.c (struct vmodifiers): Remember what modifiers were seen.
725 (parse_var_assignment): New function to parse variable assignments.
726 (eval): Call the new function. Handle variable assignments earlier.
728 * variable.c (parse_variable_definition): Only parse; don't create var.
729 (assign_variable_definition): Call parse, then create the var.
731 2009-05-24 Paul Smith <psmith@gnu.org>
733 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
734 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
736 2009-03-14 Eli Zaretskii <eliz@gnu.org>
738 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
739 Fixes Savannah bug #25412.
741 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
742 prototype for xmalloc.
743 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
744 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
745 Loop over an array of extensions, instead of duplicating the same
746 code inline. Use SearchPath followed by CreateFile, instead of
747 the obsolete OpenFile. Fixes Savannah bug #17277.
748 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
749 to `find_file'. Fixes Savannah bug #25662.
751 2009-03-07 Eli Zaretskii <eliz@gnu.org>
753 * function.c (func_shell): Don't close pipedes[1] if it is -1.
754 Fixes Savannah bug #20495.
756 2009-02-28 Ralf Wildenhues <address@hidden>
758 * doc/make.texi (Instead of Execution): Document interaction of
759 -t with phony targets.
761 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
763 Introduce a new keyword "private" which applies to target-specific
764 variables and prevents their values from being inherited.
766 * variable.h (struct variable): Add private_var flag to each variable.
767 Add a flag to specify which list entry switches to the parent target.
768 * variable.c (define_variable_in_set): Initialize private_var flag.
769 (lookup_variable): Skip private variables in parent contexts.
770 (initialize_file_variables): Set next_is_parent appropriately.
771 (print_variable): Show the private_var flag.
772 * read.c (eval): Recognize the private keyword.
773 (record_target_var): Set private_var.
774 * doc/make.texi (Suppressing Inheritance): Add documentation.
776 2008-10-26 Paul Smith <psmith@gnu.org>
778 * configure.in: Check for strndup().
779 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
781 * make.h: Rename savestring to xstrndup.
782 * commands.c (chop_commands): Ditto.
783 * function.c (func_foreach): Ditto.
784 * read.c (eval, record_files): Ditto.
785 * variable.c (define_variable_in_set): Ditto.
787 2008-09-30 Eli Zaretskii <eliz@gnu.org>
789 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
792 * w32/subproc/build.bat (GCCBuild): Likewise.
794 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
796 * job.c (construct_command_argv_internal): Avoid extra backslash
797 in batch-mode Unixy shells. Under DB_JOBS, display the contents
800 2008-05-31 Eli Zaretskii <eliz@gnu.org>
802 * README.W32.template: Remove obsolete text about non-support for
803 -jN without Unixy shell. Remove obsolete text about not supplying
804 Visual Studio project files (we do supply them). Modify text to
805 prefer GCC builds to MSC builds.
807 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
809 * doc/make.texi (Empty Targets): Fix typo.
811 2008-03-27 Paul Smith <psmith@gnu.org>
813 Fix Savannah bug #22379:
814 * ar.c (ar_glob_match): Zero the allocated structure.
815 * read.c (parse_file_seq): Ditto.
817 2008-03-08 Brian Dessent <brian@dessent.net>
819 * maintMakefile: Update Translation Project location.
821 2008-01-26 Eli Zaretskii <eliz@gnu.org>
823 * variable.c (target_environment): Don't use shell_var if its
824 `value' field is NULL.
826 2007-12-22 Eli Zaretskii <eliz@gnu.org>
828 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
830 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
831 (TEXINFOS): Value changed to `doc/make.texi'.
832 (.SUFFIXES): Use .texi instead of .texinfo.
833 (make.info, make.dvi): Depend on doc/make.texi.
834 (.texi.info): New target, instead of ".texinfo.info". Change -I
835 switch to $(MAKEINFO) to look in doc/. Use --no-split.
836 (.texi): New target, instead of ".texinfo". Change -I switch to
837 $(MAKEINFO) to look in doc/. Use --no-split.
838 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
839 switch to $(MAKEINFO) to look in doc/.
840 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
841 "*.i[0-9][0-9]" (due to --no-split above).
842 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
843 (html, make_1.html): New targets.
844 (.PHONY): Add "html".
845 (.SUFFIXES): Add .html.
847 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
849 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
850 HAVE_DECL_SYS_SIGLIST.
852 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
853 build does not use child_execute_job.
855 * variable.c (define_automatic_variables) [__MSDOS__]: Always
856 export the SHELL environment variable to the child.
858 2007-12-22 Eli Zaretskii <eliz@gnu.org>
860 * config.h.W32: Include sys/types.h.
861 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
863 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
864 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
867 2007-11-04 Paul Smith <psmith@gnu.org>
869 * doc/make.texi: Convert references to "commands", "command
870 lines", and "command script" to "recipe".
872 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
875 2007-10-27 Bruno Haible <bruno@clisp.org>
877 * remake.c (f_mtime): Print time difference values between 100 and
878 ULONG_MAX in fixed-point notation rather than in exponention notation.
880 2007-10-12 Eli Zaretskii <eliz@gnu.org>
882 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
883 a more complex value than a simple shell: if it's not a default
884 shell now then expand it and see if is a default shell then.
886 2007-10-10 Eli Zaretskii <eliz@gnu.org>
888 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
889 pathnames, with const strings.
890 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
891 from the template (used for building from CVS, not a dist).
893 2007-10-10 Paul Smith <psmith@gnu.org>
895 * make.h: Add a prototype for w32_kill() (change suggested by
896 Yongwei Wu <wuyongwei@gmail.com>).
898 2007-09-21 Eli Zaretskii <eliz@gnu.org>
900 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
903 2007-09-12 Paul Smith <psmith@gnu.org>
905 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
906 Provided by Diego Biurrun <diego@biurrun.de>
907 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
908 Provided by Diego Biurrun <diego@biurrun.de>
910 2007-09-11 Paul Smith <psmith@gnu.org>
912 * doc/make.texi (Special Variables): Moved this into the "How to
913 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
914 (MAKEFILE_LIST) No longer a section; this was added into the
915 "Special Variables" section.
916 (Rule Introduction): Reference .RECIPEPREFIX.
917 (Simple Makefile): Ditto.
918 (Rule Syntax): Ditto.
919 (Command Syntax): Ditto.
920 (Error Messages): Ditto.
922 2007-09-10 Paul Smith <psmith@gnu.org>
924 * commands.c (print_commands): Don't print an extra line in the
925 command scripts. Prefix the command scripts with cmd_prefix, not \t.
927 * read.c (construct_include_path): Add the full string to the cache; we
928 were chopping the last char.
930 * NEWS: Announce the .RECIPEPREFIX special variable.
931 * variable.c (lookup_special_var): Rename from handle_special_var().
932 (lookup_variable): Call the new name.
933 (set_special_var): New function: handle setting of special variables.
934 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
935 (do_variable_definition): Call it.
936 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
937 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
938 * main.c (main): Create the .RECIPEPREFIX special variable.
939 * read.c (eval): Remove the cmd_prefix characters from the command
940 scripts here, so they're not stored in the commands array at all,
941 rather than waiting and stripping them out during command construction.
942 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
944 2007-08-15 Paul Smith <psmith@gnu.org>
946 * doc/make.texi (GNU Free Documentation License): The fdl.texi
947 file has had the section info removed, so add some to make.texi
948 before we include it.
950 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
952 * remake.c (check_dep): Reset the target state for intermediate
953 files. They might have been considered before but not updated
954 then (order-only for example) but they will be this time.
955 Fixes Savannah bug #'s 3330 and 15919.
957 2007-07-21 Eli Zaretskii <eliz@gnu.org>
959 Fix Savannah bug #20549:
960 * function.c (func_shell): Call construct_command_argv with zero
962 * job.c (construct_command_argv_internal): New argument FLAGS; all
964 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
966 * job.h (construct_command_argv_internal): Update prototype.
968 2007-07-13 Paul Smith <psmith@gnu.org>
970 * file.c (expand_deps): Use variable_buffer as the start of the
971 buffer, not the original pointer (in case it was reallocated).
972 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
973 Fixes Savannah bug #20452.
975 2007-07-04 Paul Smith <psmith@gnu.org>
977 * (ALL FILES): Update to GPLv3.
978 * (ALL FILES): Update copyright for 2007.
980 * main.c (print_version): Move the host type info to the second line.
982 2007-06-29 Thiemo Seufer <ths@mips.com>
984 * maintMakefile: Update Translation Project location.
986 2007-06-13 Paul Smith <psmith@gnu.org>
988 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
989 "Expansion of a deferred"
990 Fixes Savannah bug #20018.
992 * expand.c (variable_expand_for_file): Preserve the value of
993 reading_file rather than setting it to 0 at the end.
994 Fixes Savannah bug #20033.
996 2007-05-11 Paul Smith <psmith@gnu.org>
998 * job.c (new_job): Add debug info to specify where make found the
999 command script it is running to build a target.
1000 Fixes Savannah bug #18617.
1002 * default.c (default_suffixes,default_suffix_rules,default_variables):
1003 Add support for Objective C. Fixes Savannah bug #16389.
1004 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1006 * function.c (func_lastword): Initialize p.
1008 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1009 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1010 Dave Korn <dave.korn@artimi.com>
1012 2007-05-08 Paul Smith <psmith@gnu.org>
1014 Fix Savannah bug #19656:
1016 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1018 * make.h: Change all case-insensitive string compares to use
1019 strcasecmp() (from POSIX). If we don't have that but do have one
1020 of the others, define strcasecmp to be one of those instead. If
1021 we don't have any, declare a prototype for our own version.
1023 * misc.c (strcasecmp): Use this if we can't find any native
1024 case-insensitive string comparison function.
1025 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1026 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1028 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1029 strcasecmp() instead of stricmp().
1030 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1031 instead of strcmpi().
1032 * acinclude.m4: Remove the strcasecmp() check from here.
1034 2007-03-21 Paul Smith <psmith@gnu.org>
1036 * configure.in: Don't turn on case-insensitive file system support
1037 if --disable-... is given. Fixes Savannah bug #19348.
1039 2007-03-19 Paul Smith <psmith@gnu.org>
1041 * ALL: Use the strcache for all file name strings, or other
1042 strings which we will never free. The goal is to save memory by
1043 avoiding duplicate copies of strings. However, at the moment this
1044 doesn't save much memory in most situations: due to secondary
1045 expansion we actually save prerequisite lists twice (once before
1046 the secondary expansion, and then again after it's been parsed
1047 into individual file names in the dep list). We will resolve this
1048 in a future change, by doing the parsing up-front for targets
1049 where secondary expansion is not set.
1051 Moving things into the strcache also allows us to use const
1052 pointers in many more places.
1054 2007-01-03 Paul Smith <psmith@gnu.org>
1056 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1057 the function, not just the first. Fixes Savannah bug #18680.
1059 2006-11-18 Paul Smith <psmith@gnu.org>
1061 * strcache.c (strcache_add_len): Don't allocate a new buffer
1062 unless the string is not already nil-terminated. Technically this
1063 is a violation of the standard, since we may be passed an array
1064 that is not long enough to test one past. However, in make this
1065 is never true since we only use nil-terminated strings or
1066 sub-strings thereof.
1068 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1070 * main.c: New global cmd_prefix, defaults to '\t'.
1071 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1074 * dir.c: Constified.
1075 (dir_contents_file_exists_p): Check for an error return from
1076 readdir(), just in case.
1078 * commands.c: Constified.
1079 * default.c: Constified.
1080 * expand.c: Constified.

1178 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned

1234 Declare and define sh_chars_sh[].
1236 2006-03-23 Paul D. Smith <psmith@gnu.org>
1238 * configure.in: Look for build.sh.in in $srcdir so it will be
1239 built for remote configurations as well.
1241 * Makefile.am: Make sure to clean up build.sh during distclean.
1242 Fixes Savannah bug #16166.
1244 * misc.c (log_access): Takes a const char *.

1250 * implicit.c (pattern_search): Call set_file_variables only
1251 if we have prerequisites that need second expansion. Fixes
1252 Savannah bug #16140.

1272 allow multiple concurrent runs.
1273 Patch from Joseph Myers <joseph@codesourcery.com>
1275 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1277 * dep.h (struct dep): Add the stem field.
1278 * misc.c (alloc_dep, free_dep): New functions.

1280 (free_dep_chain): Use free_dep.
1281 * read.c (record_files): Store stem in the dependency line.
1282 * file.c (expand_deps): Use stem stored in the dependency line. Use
1283 free_dep_chain instead of free_ns_chain.
1284 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1285 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1290 2006-03-14 Paul D. Smith <psmith@gnu.org>

1295 (allocated_variable_append): Don't expand the final result.
1296 Fixes Savannah bug #15913.
1298 2006-03-09 Paul Smith <psmith@gnu.org>
1300 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1301 listed non-existent files as changed. Turns out there's a bug in
1302 the Linux kernel builds which means that this change causes
1303 everything to rebuild every time. We will re-introduce this fix
1304 in the next release, to give them time to fix their build system.
1305 Fixes Savannah bug #16002.
1306 Introduces Savannah bug #16051.
1308 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1315 locator function find_and_set_default_shell if SHELL came from the

1320 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1321 to be null; don't core in that case.
1323 2006-02-19 Paul D. Smith <psmith@gnu.org>
1325 * commands.c (set_file_variables): Realloc, not malloc, the static
1326 string values to avoid memory leaks.
1328 * expand.c (recursively_expand_for_file): Only set reading_file to
1329 an initialized value.
1331 * implicit.c (pattern_search): We need to make a copy of the stem
1332 if we get it from an intermediate dep, since those get freed.
1334 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1336 (enter_file) [VMS]: Ditto.
1337 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1341 * job.c (construct_command_argv_internal): Fix last change.
1343 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1344 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1345 the calls to _beginthreadex.
1347 * expand.c (recursively_expand_for_file): Initialize `save' to
1348 prevent compiler warnings.
1350 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1352 * job.c (construct_command_argv_internal): Don't create a temporary
1353 script/batch file if we are under -n. Call _setmode to switch the
1354 script file stream to text mode.
1356 2006-02-17 Paul D. Smith <psmith@gnu.org>
1358 * variable.c (merge_variable_set_lists): Don't try to merge the
1359 global_setlist. Not only is this useless, but it can lead to
1360 circularities in the linked list, if global_setlist->next in one
1361 list gets set to point to another list which also ends in
1363 Fixes Savannah bug #15757.
1365 2006-02-15 Paul D. Smith <psmith@gnu.org>
1367 Fix for Savannah bug #106.
1369 * expand.c (expanding_var): Keep track of which variable we're
1370 expanding. If no variable is being expanded, it's the same as
1372 * make.h (expanding_var): Declare it.
1373 * expand.c (recursively_expand_for_file): Set expanding_var to the
1374 current variable we're expanding, unless there's no file info in
1375 it (could happen if it comes from the command line or a default
1376 variable). Restore it before we exit.
1377 * expand.c (variable_expand_string): Use the expanding_var file
1378 info instead of the reading_file info.
1379 * function.c (check_numeric): Ditto.
1381 (func_wordlist): Ditto.
1382 (func_error): Ditto.
1383 (expand_builtin_function): Ditto.
1384 (handle_function): Ditto.
1386 2006-02-14 Paul D. Smith <psmith@gnu.org>
1388 * read.c (eval): Even if the included filenames expands to the
1389 empty string we still need to free the allocated buffer.
1391 * implicit.c (pattern_search): If we allocated a variable set for
1392 an impossible file, free it.
1393 * variable.c (free_variable_set): New function.
1394 * variable.h: Declare it.
1396 * read.c (read_all_makefiles): Makefile names are kept in the
1397 strcache, so there's never any need to alloc/free them.
1400 * main.c (main): Add "archives" to the .FEATURES variable if
1401 archive support is enabled.
1402 * doc/make.texi (Special Variables): Document it.
1404 2006-02-13 Paul D. Smith <psmith@gnu.org>

1412 * (ALL FILES): Updated copyright and license notices.
1414 2006-02-10 Paul D. Smith <psmith@gnu.org>
1416 A new internal capability: the string cache is a read-only cache
1417 of strings, with a hash table interface for fast lookup. Nothing
1418 in the cache will ever be freed, so there's no need for reference
1419 counting, etc. This is the beginning of a full solution for
1420 Savannah bug #15182, but for now we only store makefile names here.
1422 * strcache.c: New file. Implement a read-only string cache.
1423 * make.h: Add prototypes for new functions.
1424 * main.c (initialize_global_hash_tables): Initialize the string cache.
1425 (print_data_base): Print string cache stats.
1426 * read.c (eval_makefile): Use the string cache to store makefile
1427 names. Rewrite the string allocation to be sure we free everything.
1429 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1431 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1432 directory time stamp didn't change, except on FAT filesystems.
1433 Suggested by J. David Bryan <jdbryan@acm.org>.
1435 2006-02-09 Paul D. Smith <psmith@gnu.org>
1437 * function.c (func_or): Implement a short-circuiting OR function.
1438 (func_and): Implement a short-circuiting AND function.
1439 (function_table_init): Update the table with the new functions.
1440 * doc/make.texi (Conditional Functions): Changed the "if" section
1441 to one on general conditional functions. Added documentation for
1442 $(and ...) and $(or ...) functions.
1443 * NEWS: Note new $(and ...) and $(or ...) functions.

1450 one in struct file. Fixes Savannah bug #15641.
1452 2006-02-06 Paul D. Smith <psmith@gnu.org>
1454 * vpath.c (selective_vpath_search): If the file we find has a
1455 timestamp from -o or -W, use that instead of the real time.
1456 * remake.c (f_mtime): If the mtime is a special token from -o or
1457 -W, don't overwrite it with the real mtime.
1458 Fixes Savannah bug #15341.

1463 (process_signal, process_last_err, process_exit_code): Manage
1464 invalid handle values.
1465 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1466 manage invalid handles; remove them.

1468 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1475 Fixes Savannah bug #15533.
1476 * filedef.h (struct file): Add a new LAST pointer.
1478 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1479 the comparison. For 64-bits systems the result of the subtraction
1480 might not fit into an int. Use comparison instead.
1481 Fixes Savannah bug #15534.
1483 * doc/make.texi: Update the chapter on writing commands to reflect
1484 the changes made in 3.81 for backslash/newline and SHELL handling.
1486 2006-02-01 Paul D. Smith <psmith@gnu.org>
1488 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1489 variable st is not used when it's not initialized.

1504 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1506 * remake.c (update_goal_chain): Set g->changed instead of
1507 incrementing it, as it is only 8-bit wide, and could overflow if
1508 many commands got started in update_file.
1510 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1512 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1530 the shell is not sh.exe.
1532 * job.c (create_batch_file): Renamed from create_batch_filename;
1533 all callers changed. Don't close the temporary file; return its
1534 file descriptor instead. New arg FD allows to return the file
1536 (construct_command_argv_internal): Use _fdopen instead of fopen to
1537 open the batch file.
1539 2006-01-04 Paul D. Smith <psmith@gnu.org>

1568 * doc/make.texi (Execution): Add a footnote about changes in
1569 handling of backslash-newline sequences. Mention the differences
1570 on MS-DOS and MS-Windows.
1572 * NEWS: More details about building the MinGW port and a pointer
1573 to README.W32. Fix the section name that describes the new
1574 backward-incompatible processing of backslash-newline sequences.
1575 The special processing of SHELL set to "cmd" is only relevant to
1576 MS-Windows, not MS-DOS.
1578 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1580 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1581 to DWORD, to avoid compiler warnings.

1603 * make.1: Fix some display errors and document all existing options.
1604 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1606 2005-12-11 Paul D. Smith <psmith@gnu.org>
1608 * implicit.c (pattern_search): If 2nd expansion is not set for
1609 this implicit rule, replace the pattern with the stem directly,
1610 and don't re-expand the variable list. Along with the other
1611 .SECONDEXPANSION changes below, fixes bug #13781.
1613 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1615 * implicit.c (pattern_search): Mark other files that this rule
1616 builds as targets so that they are not treated as intermediates
1617 by the pattern rule search algorithm. Fixes bug #13022.
1619 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1621 * remake.c (notice_finished_file): Propagate the change of
1622 modification time to all the double-colon entries only if
1623 it is the last one to be updated. Fixes bug #14334.
1625 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1627 * function.c (func_flavor): Implement the flavor function which
1628 returns the flavor of a variable.
1629 * doc/make.texi (Functions for Transforming Text): Document it.
1630 * NEWS: Add it to the list of new functions.
1632 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1634 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1636 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1637 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1639 2005-10-26 Paul Smith <psmith@gnu.org>
1641 * read.c (record_files): Don't set deps flags if there are no deps.
1642 * maintMakefile: We only need to build the templates when we are
1643 creating a distribution, so don't do it for "all".
1645 2005-10-24 Paul D. Smith <psmith@gnu.org>
1647 Make secondary expansion optional: its enabled by declaring the
1648 special target .SECONDEXPANSION.
1650 * NEWS: Update information on second expansion capabilities.
1651 * doc/make.texi (Secondary Expansion): Document the
1652 .SECONDEXPANSION special target and its behavior.
1653 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1654 prerequisite list was found in a static pattern rule.
1655 (free_dep_chain): Declare a prototype.
1656 * file.c (parse_prereqs): New function: break out some complexity
1658 (expand_deps): If we aren't doing second expansion, replace % with
1659 the stem for static pattern rules. Call the new function.
1660 * filedef.h (parse_prereqs): Declare a prototype.
1661 * implicit.c (pattern_search): Initialize the new staticpattern
1663 * main.c (second_expansion): Declare a global variable to remember
1664 if the special target has been seen. Initialize the new
1665 staticpattern field for prerequisites.
1666 * make.h: Extern for second_expansion.
1667 * misc.c (free_dep_chain): New function: frees a struct dep list.
1668 * read.c (read_all_makefiles): Initialize the staticpattern field.
1669 (eval_makefile): Ditto.
1670 (record_files): Check for the .SECONDEXPANSION target and set
1671 second_expansion global if it's found.
1672 Use the new free_dep_chain() instead of doing it by hand.
1673 Set the staticpattern field for prereqs of static pattern targets.
1675 2005-10-16 Paul D. Smith <psmith@gnu.org>
1677 * main.c (main): Set CURDIR to be a file variable instead of a
1678 default, so that values of CURDIR inherited from the environment
1679 won't override the make value.
1681 2005-09-26 Paul D. Smith <psmith@gnu.org>
1683 * job.c (construct_command_argv_internal): If the line is empty
1684 remember to free the temporary argv strings.
1687 2005-09-16 Paul D. Smith <psmith@gnu.org>
1689 * job.c (start_job_command): The noerror flag is a boolean (single
1690 bit); set it appropriately.
1691 Reported by Mark Eichin <eichin@metacarta.com>
1693 2005-08-29 Paul D. Smith <psmith@gnu.org>
1695 * function.c (func_error): On Windows, output from $(info ...)
1696 seems to come in the wrong order. Try to force it with fflush().
1698 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1700 * read.c (record_files): Move code that sets stem for static
1701 pattern rules out of the if (!two_colon) condition so it is
1702 also executed for two-colon rules. Fixes Savannah bug #13881.
1704 2005-08-08 Paul D. Smith <psmith@gnu.org>
1706 * make.h: Don't test that __STDC__ is non-0. Some compilers
1707 (Windows for example) set it to 0 to denote "ISO C + extensions".
1710 2005-08-07 Paul D. Smith <psmith@gnu.org>
1712 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1713 conditional (slightly different version of a fix from Eli).
1715 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1716 If make is running in parallel without -k and two jobs die in a
1717 row, but not too close to each other, then make will quit without
1718 waiting for the rest of the jobs to die.
1720 * main.c (die): Don't reset err before calling reap_children() the
1721 second time: we still want it to be in the error condition.
1722 * job.c (reap_children): Use a static variable, rather than err,
1723 to control whether or not the error message should be printed.
1725 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1727 * w32/subproc/sub_proc.c: Include signal.h.
1728 (process_pipe_io, process_file_io): Pass a pointer to a local
1729 DWORD variable to GetExitCodeProcess. If the exit code is
1730 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1732 * job.c [WINDOWS32]: Include windows.h.
1733 (main_thread) [WINDOWS32]: New global variable.
1734 (reap_children) [WINDOWS32]: Get the handle for the main thread
1735 and store it in main_thread.
1737 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1738 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1739 doing anything else. When we are done, close the main thread
1740 handle and exit with status 130.
1742 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1744 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1747 * main.c (find_and_set_default_shell): If found a DOSish shell,
1748 set sh_found and the value of default_shell, and report the
1749 findings in debug mode.
1751 * job.c (construct_command_argv_internal): Check unixy_shell, not
1752 no_default_sh_exe, to decide whether to use Unixy or DOSish
1755 * README.W32: Update with info about the MinGW build.
1757 * build_w32.bat: Support MinGW.
1759 * w32/subproc/build.bat: Likewise.
1761 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1762 printing DWORD args.
1764 * function.c (windows32_openpipe): Fix format strings for printing
1767 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1769 (start_job_command): Fix format string for printing the result of
1771 (start_job_command) [WINDOWS32]: Do not define.
1772 (exec_command): Fix format string for printing HANDLE args.
1774 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1775 to avoid compiler warnings.
1776 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1777 (Note: some of these fixes were submitted independently by J. Grant)
1779 2005-07-30 J. Grant <jg@jguk.org>
1781 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1782 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1783 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1785 2005-07-15 Paul Smith <psmith@gnu.org>
1787 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1788 we don't have a POSIX shell, then revert to the old
1789 backslash-newline behavior (where they are stripped).
1792 2005-07-08 Paul D. Smith <psmith@gnu.org>
1794 * config.h.W32.template: Reorder to match the standard config.h,
1795 for easier comparisons.
1796 From J. Grant <jg@jguk.org>
1798 * maintMakefile: Remove .dep_segment before overwriting it, in
1799 case it's not writable or noclobber is set.
1800 * expand.c (variable_expand_string): Cast result of pointer
1801 arithmetic to avoid a warning.
1802 * main.c (switches): Add full-fledged final initializer.
1804 2005-07-06 Paul D. Smith <psmith@gnu.org>
1806 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1807 * signame.c (strsignal): If we found _sys_siglist[] or
1808 __sys_siglist[] use those instead of sys_siglist[].
1809 From Albert Chin <china@thewrittenword.com>
1811 2005-07-04 Paul D. Smith <psmith@gnu.org>
1813 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1814 globfree(); set up to use the GNU versions.
1815 From Martin Zinser <zinser@zinser.no-ip.info>
1817 2005-07-03 Paul D. Smith <psmith@gnu.org>
1819 From J. Grant <jg@jguk.org>:
1821 * README.W32.template: Update the Windows and tested MSVC versions.
1822 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1823 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1824 * build_w32.bat: Ditto.
1825 * w32/subproc/build.bat: Ditto.
1827 2005-06-28 Paul D. Smith <psmith@gnu.org>
1829 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1830 declaration was checked but not present.
1832 2005-06-27 Paul D. Smith <psmith@gnu.org>
1834 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1835 to unsigned long. Fixes Savannah bug #13550.
1837 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1838 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1839 Fixes Savannah bug #13551.
1841 2005-06-26 Paul D. Smith <psmith@gnu.org>
1843 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1844 it if ANSI_STRING is not set.
1846 2005-06-25 Paul D. Smith <psmith@gnu.org>
1848 * read.c (eval): If no filenames are passed to any of the
1849 "include" variants, don't print an error.
1850 * doc/make.texi (Include): Document this.
1851 Fixes Savannah bug #1761.
1853 * job.c (construct_command_argv_internal): Sanitize handling of
1854 backslash/newline pairs according to POSIX: that is, keep the
1855 backslash-newline in the command script, but remove a following
1856 TAB character, if present. In the fast path, make sure that the
1857 behavior matches what the shell would do both inside and outside
1858 of quotes. In the slow path, quote the backslash and put a
1859 literal newline in the string.
1860 Fixes Savannah bug #1332.
1861 * doc/make.texi (Execution): Document the new behavior and give
1863 * NEWS: Make a note of the new behavior.
1865 * make.h [WINDOWS32]: #include <direct.h>.
1866 Fixes Savannah bug #13478.
1868 * remake.c (name_mtime): If the stat() of a file fails and the -L
1869 option was given and the file is a symlink, take the best mtime of
1870 the symlink we can get as the mtime of the file and don't fail.
1871 Fixes Savannah bug #13280.
1873 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1874 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1875 inside a variable reference. Make this function static as it's
1877 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1878 parsing an unexpanded line looking for semicolons.
1879 Fixes Savannah bug #1454.
1880 * misc.c (remove_comments): Move this to read.c and make it static
1881 as it's only used there. Call find_char_unquote() with new arg.
1882 * make.h: Remove prototypes for find_char_unquote() and
1883 remove_comments() since they're static now.
1885 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1886 its export flag and obtain its value. When we need to re-exec,
1887 increment the value and add it into the environment.
1888 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1889 * NEWS: Mention MAKE_RESTARTS.
1890 * main.c (always_make_set): New variable. Change the -B option to
1891 set this one instead.
1892 (main): When checking makefiles, only set always_make_flag if
1893 always_make_set is set AND the restarts flag is 0. When building
1894 normal targets, set it IFF always_make_set is set.
1895 (main): Avoid infinite recursion with -W, too: only set what-if
1896 files to NEW before we check makefiles if we've never restarted
1897 before. If we have restarted, set what-if files to NEW _after_ we
1899 Fixes Savannah bug #7566:
1901 2005-06-17 Paul D. Smith <psmith@gnu.org>
1903 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1904 in the prerequisites list.
1906 2005-06-12 Paul D. Smith <psmith@gnu.org>
1908 Fix Savannah bug # 1328.
1910 * configure.in: Check for atexit().
1911 * misc.c (close_stdout): Test stdout to see if writes to it have
1912 failed. If so, be sure to exit with a non-0 error code. Based on
1913 code found in gnulib.
1914 * make.h: Prototype.
1915 * main.c (main): Install close_stdout() with atexit().
1917 2005-06-10 Paul D. Smith <psmith@gnu.org>
1919 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1921 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1922 headers; make vmsWaitForChildren() static; extern vmsify().
1923 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1924 Don't create child_execute_job() here (it's in vmsjobs.c).
1925 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1927 2005-06-09 Paul D. Smith <psmith@gnu.org>
1929 * variable.c (push_new_variable_scope): File variables point
1930 directly to the global_setlist variable. So, inserting a new
1931 scope in front of that has no effect on those variables: they
1932 don't go through current_variable_set_list. If we're pushing a
1933 scope and the current scope is global, push it "the other way" so
1934 that the new setlist is in the global_setlist variable, and
1935 next points to a new setlist with the global variable set.
1936 (pop_variable_scope): Properly undo a push with the new
1938 Fixes Savannah bug #11913.
1940 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1942 * job.c (reap_children): Don't die of the command failed but
1943 the dontcare flag is set. Fixes Savannah bug #13216.
1945 * implicit.c (pattern_search): When creating a target from
1946 an implicit rule match, lookup pattern target and set precious
1947 flag in a newly created target. Fixes Savannah bug #13218.
1949 2005-05-13 Paul D. Smith <psmith@gnu.org>
1951 Implement "if... else if... endif" syntax.
1953 * read.c (eval): Push all checks for conditional words ("ifeq",
1954 "else", etc.) down into the conditional_line() function.
1955 (conditional_line): Rework to allow "else if..." clause. New
1956 return value -2 for lines which are not conditionals. The
1957 ignoring flag can now also be 2, which means "already parsed a
1958 true branch". If that value is seen no other branch of this
1959 conditional can be considered true. In the else parsing if there
1960 is extra text after the else, invoke conditional_line()
1961 recursively to see if it's another conditional. If not, it's an
1962 error. If so, raise the conditional value to this level instead
1963 of creating a new conditional nesting level. Special check for
1964 "else" and "endif", which aren't allowed on the "else" line.
1965 * doc/make.texi (Conditional Syntax): Document the new syntax.
1967 2005-05-09 Paul D. Smith <psmith@gnu.org>
1969 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1970 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1971 recurses to the w32 directory, even on non-Windows systems. Use
1972 the method suggested in the automake manual.
1973 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1974 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1976 2005-05-07 Paul D. Smith <psmith@gnu.org>
1978 * main.c (die): If we're dying with a fatal error (not that a
1979 command has failed), write back any leftover tokens before we go.
1981 * job.c (set_child_handler_action_flags): If there are jobs
1982 waiting for the load to go down, set an alarm to go off in 1
1983 second. This allows us to wake up from a potentially long-lasting
1984 read() and start a new job if the load has gone down. Turn it off
1986 (job_noop): Dummy signal handler function.
1987 (new_job): Invoke it with the new semantics.
1989 * docs/make.texi: Document secondary expansion. Various cleanups
1992 2005-05-03 Paul D. Smith <psmith@gnu.org>
1994 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1995 the targets which are to ultimately be made are called "goals";
1996 see the GNU make manual. Also, MAKECMDGOALS, etc.
1998 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1999 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2000 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2002 2005-05-02 Paul D. Smith <psmith@gnu.org>
2004 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2005 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2006 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2007 functions to vmsjobs.c. #include it into jobs.c.
2009 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2010 jobserver tokens. I found that this happens when an exported
2011 recursive variable contains a $(shell ...) function reference: in
2012 this situation we could "forget" to write back a token.
2014 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2015 we have. It's not reliable to depend on the number of children in
2016 our linked list so keep a separate count.
2017 (new_job): Check jobserver_tokens rather than children &&
2018 waiting_jobs. Increment jobserver_tokens when we get one.
2019 (free_child): If jobserver_tokens is 0, internal error. If it's
2020 >1, write a token back to the jobserver pipe (we don't write a
2021 token for the "free" job). Decrement jobserver_tokens.
2023 * main.c: Add variable master_job_slots.
2024 (main): Set it to hold the number of jobs requested if we're the
2025 master process, when using the jobserver.
2026 (die): Sanity checks: first test jobserver_tokens to make sure
2027 this process isn't holding any tokens we didn't write back.
2028 Second, if master_job_slots is set count the tokens left in the
2029 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2031 2005-04-24 Paul D. Smith <psmith@gnu.org>
2033 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2034 with -l# can lose jobserver tokens, because waiting jobs are not
2035 consulted properly when checking for the "free" token.
2037 * job.c (free_child): Count waiting_jobs as having tokens.
2038 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2039 handle jobs waiting for the load to drop.
2041 2005-04-23 Paul D. Smith <psmith@gnu.org>
2043 * main.c (main): Be careful to not core if a variable setting in
2044 the environment doesn't contain an '='. This is illegal but can
2045 happen in broken setups.
2046 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2048 2005-04-12 Paul D. Smith <psmith@gnu.org>
2050 The second expansion feature causes significant slowdown. Timing
2051 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2052 read the makefile before the feature, to 11+s to do the same
2053 operations after the feature. Additionally, memory usage
2054 increased drastically. To fix this I added some intelligence that
2055 avoids the overhead of the second expansion unless it's required.
2057 * dep.h: Add a new boolean field, need_2nd_expansion.
2059 * read.c (eval): When creating the struct dep for the target,
2060 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2061 (record_files): If there's a "%" in a static pattern rule, it gets
2062 converted to "$*" so set need_2nd_expansion to 1.
2064 * file.c (expand_deps): Rework to be more efficient. Only perform
2065 initialize_file_variables(), set_file_variables(), and
2066 variable_expand_for_file() if the need_2nd_expansion is set.
2068 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2069 (pattern_search): Ditto.
2070 * main.c (handle_non_switch_argument): Ditto.
2072 * read.c (read_all_makefiles): Ditto.
2073 (eval_makefile): Ditto.
2075 2005-04-07 Paul D. Smith <psmith@gnu.org>
2077 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2078 * variable.c (sync_Path_environment): Ditto.
2079 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2081 * main.c (main): Define the .FEATURES variable.
2082 * NEWS: Announce .FEATURES.
2083 * doc/make.texi (Special Variables): Document .FEATURES.
2085 * remake.c (check_dep): If a file is .PHONY, update it even if
2086 it's marked intermediate. Fixes Savannah bug #12331.
2088 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2090 * file.c (expand_deps): Factor out the second expansion and
2091 prerequisite line parsing logic from snap_deps().
2093 * file.c (snap_deps): Use expand_deps(). Expand and parse
2094 prerequisites of the .SUFFIXES special target first. Fixes
2095 Savannah bug #12320.
2097 2005-03-13 Paul D. Smith <psmith@gnu.org>
2099 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2102 2005-03-11 Paul D. Smith <psmith@gnu.org>
2104 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2105 available, not undefined (from Earnie Boyd).
2107 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2109 * implicit.c (pattern_search): Mark an intermediate target as
2110 precious if it happened to be a prerequisite of some (other)
2111 target. Fixes Savannah bug #12267.
2113 2005-03-09 Paul D. Smith <psmith@gnu.org>
2115 * read.c (eval_makefile): Add alloca(0).
2116 (eval_buffer): Ditto.
2118 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2120 * main.c (main): Use o_file instead of o_default when defining
2121 the .DEFAULT_TARGET special variable.
2122 * read.c (eval): Use define_variable_global() instead of
2123 define_variable() when setting new value for the .DEFAULT_TARGET
2124 special variable. Fixes Savannah bug #12266.
2126 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2128 * imlicit.c (pattern_search): Mark files for which an implicit
2129 rule has been found as targets. Fixes Savannah bug #12202.
2131 2005-03-04 Paul D. Smith <psmith@gnu.org>
2134 * doc/make.texi (Automatic Variables): Document $|.
2136 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2138 * read.c (record_files): Instead of substituting % with
2139 actual stem value in dependency list replace it with $*.
2140 This fixes stem triple expansion bug.
2142 * implicit.c (pattern_search): Copy stem to a separate
2143 buffer and make it a properly terminated string. Assign
2144 this buffer instead of STEM (which is not terminated) to
2145 f->stem. Instead of substituting % with actual stem value
2146 in dependency list replace it with $*. This fixes stem
2147 triple expansion bug.
2149 2005-03-01 Paul D. Smith <psmith@gnu.org>
2151 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2152 on Windows, as it takes a handle not a pid. Just exit.
2153 Fix from patch #3679, provided by Alessandro Vesely.
2155 * configure.in: Update check for sys_siglist[] from autoconf manual.
2156 * signame.c (strsignal): Update to use the new autoconf macro.
2158 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2160 * read.c (record_files): Add a check for the list of prerequisites
2161 of a static pattern rule being empty. Fixes Savannah bug #12180.
2163 2005-02-28 Paul D. Smith <psmith@gnu.org>
2165 * doc/make.texi (Text Functions): Update docs to allow the end
2166 ordinal for $(wordlist ...) to be 0.
2167 * function.c (func_wordlist): Fail if the start ordinal for
2168 $(wordlist ...) is <1. Matches documentation.
2169 Resolves Savannah support request #103195.
2171 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2172 previously we were stopping when !-q, exactly the opposite. This
2173 has been wrong since version 1.34, in 1994!
2174 (update_file): If we got an error don't break out to run more
2175 double-colon rules: just return immediately.
2176 Fixes Savannah bug #7144.
2178 2005-02-27 Paul D. Smith <psmith@gnu.org>
2180 * misc.c (end_of_token): Make argument const.
2181 * make.h: Update prototype.
2183 * function.c (abspath, func_realpath, func_abspath): Use
2184 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2185 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2186 * read.c (record_files): Ditto.
2187 * variable.c (do_variable_definition): Ditto.
2189 * function.c (func_error): Create a new function $(info ...) that
2190 simply prints the message to stdout with no extras.
2191 (function_table_init): Add new function to the table.
2192 * NEWS: Add $(info ...) reference.
2193 * doc/make.texi (Make Control Functions): Document it.
2195 New feature: if the system supports symbolic links, and the user
2196 provides the -L/--check-symlink-time flag, then use the latest
2197 mtime between the symlink(s) and the target file.
2199 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2200 readlink(). If both are available, define MAKE_SYMLINKS.
2201 * main.c: New variable: check_symlink_flag.
2202 (usage): Add a line for -L/--check-symlink-times to the help string.
2203 (switches): Add -L/--check-symlink-times command line argument.
2204 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2205 print a warning and disable it again.
2206 * make.h: Declare check_symlink_flag.
2207 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2208 if the file is a symlink then check each link in the chain and
2209 choose the NEWEST mtime we find as the mtime for the file. The
2210 newest mtime might be the file itself!
2211 * NEWS: Add information about this new feature.
2212 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2214 Avoid core dumps described in Savannah bug # 12124:
2216 * file.c: New variable snapped_deps remember whether we've run
2218 (snap_deps): Set it.
2219 * filedef.h: Extern it.
2220 * read.c (record_files): Check snapped_deps; if it's set then
2221 we're trying to eval a new target/prerequisite relationship from
2222 within a command script, which we don't support. Fatal.
2224 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2226 Implementation of the .DEFAULT_TARGET special variable.
2228 * read.c (eval): If necessary, update default_target_name when
2230 * read.c (record_files): Update default_target_file if
2231 default_target_name has changed.
2232 * main.c (default_target_name): Define.
2233 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2234 default_target_name is set use default_target_file as a root
2236 * filedef.h (default_target_name): Declare.
2237 * dep.h (free_dep_chain):
2238 * misc.c (free_dep_chain): Change to operate on struct nameseq
2239 and change name to free_ns_chain.
2240 * file.c (snap_deps): Update to use free_ns_chain.
2242 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2244 Implementation of the second expansion in explicit rules,
2245 static pattern rules and implicit rules.
2247 * read.c (eval): Refrain from chopping up rule's dependencies.
2248 Store them in a struct dep as a single dependency line. Remove
2249 the code that implements SySV-style automatic variables.
2251 * read.c (record_files): Adjust the code that handles static
2252 pattern rules to expand all percents instead of only the first
2253 one. Reverse the order in which dependencies are stored so that
2254 when the second expansion reverses them again they appear in
2255 the makefile order (with some exceptions, see comments in
2256 the code). Remove the code that implements SySV-style automatic
2259 * file.c (snap_deps): Implement the second expansion and chopping
2260 of dependency lines for explicit rules.
2262 * implicit.c (struct idep): Define an auxiliary data type to hold
2263 implicit rule's dependencies after stem substitution and
2266 * implicit.c (free_idep_chain): Implement.
2268 * implicit.c (get_next_word): Implement helper function for
2269 parsing implicit rule's dependency lines into words taking
2270 into account variable expansion requests. Used in the stem
2273 * implicit.c (pattern_search): Implement the second expansion
2274 for implicit rules. Also fixes bug #12091.
2276 * commands.h (set_file_variables): Declare.
2277 * commands.c (set_file_variables): Remove static specifier.
2279 * dep.h (free_dep_chain): Declare.
2280 * misc.c (free_dep_chain): Implement.
2282 * variable.h (variable_expand_for_file): Declare.
2283 * expand.c (variable_expand_for_file): Remove static specifier.
2285 * make.h (strip_whitespace): Declare.
2286 * function.c (strip_whitespace): Remove static specifier.
2288 2005-02-26 Paul D. Smith <psmith@gnu.org>
2290 * main.c (main): Check for ferror() when reading makefiles from stdin.
2291 Apparently some shells in Windows don't close pipes properly and
2294 2005-02-24 Jonathan Grant <jg@jguk.org>
2296 * configure.in: Add MinGW configuration options, and extra w32 code
2298 * Makefile.am: Add MinGW configuration options, and extra w32 code
2300 * main.c: Determine correct program string (after last \ without .exe).
2301 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2303 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2304 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2305 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2306 environment support.
2308 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2310 * function.c (func_shell): When initializing error_prefix, check
2311 that reading file name is not null. This fixes long-standing
2312 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2314 2005-02-09 Paul D. Smith <psmith@gnu.org>
2316 * maintMakefile: Update the CVS download URL to simplify them.
2317 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2318 downloading the .texi files from Savannah now.
2320 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2322 * main.c (handle_non_switch_argument): Only add variables to
2323 command_variables if they're not already there: duplicate settings
2324 waste space and can be confusing to read.
2326 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2327 this header is never included by non-WINDOWS32 code, and it
2328 requires <config.h> to define which isn't always included first.
2330 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2331 testing MINGW32 versions.
2333 * main.c (log_working_directory): flush stdout to be sure the WD
2334 change is printed before any stderr messages show up.
2336 2005-02-01 Paul D. Smith <psmith@gnu.org>
2338 * maintMakefile (po_repo): Update the GNU translation site URL.
2340 2004-12-01 Paul D. Smith <psmith@gnu.org>
2342 * main.c (main): Change char* env_shell to struct variable shell_var.
2343 * variable.c (target_environment): Use new shell_var.
2345 2004-11-30 Paul D. Smith <psmith@gnu.org>
2347 * configure.in: The old way we avoided creating build.sh from
2348 build.sh.in before build.sh.in exists doesn't work anymore; we
2349 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2350 the help!). This also keeps automake from complaining.
2351 * Makefile.am (README): Add a dummy target so automake won't
2352 complain that this file doesn't exist when we checkout from CVS.
2353 * maintMakefile (.dep_segment): Rewrite this rule since newer
2354 versions of automake don't provide DEP_FILES.
2356 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2358 Implementation of `realpath' and `abspath' built-in functions.
2360 * configure.in: Check for realpath.
2361 * function.c (abspath): Return an absolute file name that does
2362 not contain any `.' or `..' components, nor repeated `/'.
2363 * function.c (func_abspath): For each name call abspath.
2364 * function.c (func_realpath): For each name call realpath
2365 from libc or delegate to abspath if realpath is not available.
2366 * doc/make.texi (Functions for File Names): Document new functions.
2367 * doc/make.texi (Quick Reference): Ditto.
2369 2004-11-28 Paul D. Smith <psmith@gnu.org>
2371 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2372 arguments. Fixes bug #10252.
2374 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2376 * main.c (main): Set SHELL to v_noexport by default. Remember the
2377 original environment setting of SHELL in the env_shell variable.
2378 * main.h: Export new env_shell variable.
2379 * variable.c (target_environment): If we find a v_noexport
2380 variable for SHELL, add a SHELL variable with the env_shell value.
2381 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2382 * doc/make.texi (Variables/Recursion): Ditto.
2384 2004-11-28 Paul D. Smith <psmith@gnu.org>
2386 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2387 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2388 Patch by Alessandro Vesely.
2390 2004-11-12 Paul D. Smith <psmith@gnu.org>
2392 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2393 the command line if it's inside a string.
2394 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2396 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2398 * function.c (func_lastword): New function: return last word
2399 from the list of words.
2400 * doc/make.texi: Document $(lastword ). Fix broken links in
2401 Quick Reference section.
2403 2004-10-06 Paul D. Smith <psmith@gnu.org>
2405 Apply patch from Alessandro Vesely, provided with bug # 9748.
2406 Fix use of tmpnam() to work with Borland C.
2408 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2409 construction of a temporary filename, and call new function
2410 create_batch_filename().
2411 (create_batch_filename) [WINDOWS32]: New function to create a
2414 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2416 * read.c (record_target_var): Expand simple pattern-specific
2418 * variable.c (initialize_file_variables): Do not expand simple
2419 pattern-specific variable.
2421 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2423 * remake.c (update_file_1): When rebuilding makefiles inherit
2424 dontcare flag from a target that triggered update.
2426 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2428 * variable.c (initialize_file_variables): Mark pattern-specific
2429 variable as a per-target and copy export status.
2431 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2433 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2435 * implicit.c (pattern_search): When considering an implicit rule's
2436 prerequisite check that it is actually a target rather then
2437 just an entry in the file hashtable.
2439 2004-09-21 Paul D. Smith <psmith@gnu.org>
2441 * read.c (readstring): Fix some logic errors in backslash handling.
2442 (eval): Remove some unnecessary processing in buffer handling.
2443 (record_target_var): Assert that parse_variable_definition() succeeded.
2444 Reported by: Markus Mauhart <qwe123@chello.at>.
2446 * misc.c: Removed the sindex() function. All instances of this
2447 function were trivially replaceable by the standard strstr()
2448 function, and that function will always have better (or certainly
2449 no worse) performance than the very simple-minded algorithm
2450 sindex() used. This can matter with complex makefiles.
2451 * make.h: Remove the prototype for sindex().
2452 * function.c (subst_expand): Convert sindex() call to strstr().
2453 This means we no longer need to track the TLEN value so remove that.
2454 (func_findstring): Convert sindex() to strstr().
2455 * commands.c (chop_commands): Convert sindex() calls to strstr().
2456 Suggested by: Markus Mauhart <qwe123@chello.at>.
2458 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2459 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2460 If SHELL is set to CMD.EXE then assume it's batch-mode and
2461 non-unixy. I wrote the code differently from the patch, though,
2462 to make it safer. This also resolves bug #9174.
2464 2004-09-20 Paul D. Smith <psmith@gnu.org>
2466 * expand.c (variable_expand_string): Modify to invoke
2467 patsubst_expand() instead of subst_expand(); the latter didn't
2468 handle suffix patterns correctly.
2469 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2470 was used only from variable_expand_string() and is no longer used
2472 (func_subst): Ditto, on call to subst_expand().
2473 (patsubst_expand): Require the percent pointers to point to the
2474 character after the %, not to the % itself.
2475 * read.c (record_files): New call criteria for patsubst_expand().
2476 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2477 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2479 2004-09-19 Paul D. Smith <psmith@gnu.org>
2481 * function.c (subst_expand): Fix a check in by_word: look for a
2482 previous blank if we're beyond the beginning of the string, not
2483 the beginning of the word.
2484 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2486 2004-05-16 Paul D. Smith <psmith@gnu.org>
2488 * remake.c (update_goal_chain): Change the argument specifying
2489 whether we're rebuilding makefiles to be a global variable,
2490 REBUILDING_MAKEFILES.
2491 (complain): Extract the code that complains about no rules to make
2492 a target into a separate function.
2493 (update_file_1): If we tried to rebuild a file during the makefile
2494 rebuild phase and it was dontcare, then no message was printed.
2495 If we then try to build the same file during the normal build,
2496 print a message this time.
2497 (remake_file): Don't complain about un-remake-able files when
2498 we're rebuilding makefiles.
2500 2004-05-11 Paul D. Smith <psmith@gnu.org>
2502 * job.c (construct_command_argv_internal): OS/2 patches from
2503 Andreas Buening <andreas.buening@nexgo.de>.
2505 2004-05-10 Paul D. Smith <psmith@gnu.org>
2507 * remake.c (update_file): Don't walk the double-colon chain unless
2508 this is a double-colon rule. Fix suggested by Boris Kolpackov
2509 <boris@kolpackov.net>.
2511 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2512 * readme.vms: New section describing OpenVMS support and issues.
2513 * default.c (default_variables): Add support for IA64.
2514 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2515 without some privilege aborts make with the error
2516 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2517 pressing Ctrl+Y and the input device is no terminal. The change
2518 catches this error and just continues.
2520 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2522 2004-04-25 Paul D. Smith <psmith@gnu.org>
2524 * commands.c (set_file_variables): Set $< properly in the face of
2525 order-only prerequisites.
2526 Patch from Boris Kolpackov <boris@kolpackov.net>
2528 2004-04-21 Bob Byrnes <byrnes@curl.com>
2530 * main.c (main): Notice failures to remake makefiles.
2532 2004-03-28 Paul D. Smith <psmith@gnu.org>
2534 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2536 * job.c: No default shell for RISC OS.
2537 (load_too_high): Hard-code the return to 1.
2538 (construct_command_argv_internal): No sh_chars or sh_cmds.
2539 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2541 2004-03-20 Paul D. Smith <psmith@gnu.org>
2543 * variable.c (do_variable_definition): Don't append from the
2544 global set if a previous non-appending target-specific variable
2545 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2548 * expand.c (reference_variable): Don't give up on variables with
2549 no value that have the target-specific append flag set: they might
2550 have a value after all. Reported by Oliver Schmidt
2551 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2552 <nikulin@dx1cmd.inp.nsk.su>.
2554 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2555 refer to absolute pathnames in directories that don't exist: some
2556 portion of the makefile could create those directories before we
2557 match the pattern. Fixes bugs #775 and #108.
2559 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2561 * main.c (main): Free makefile_mtimes if we have any.
2562 * README.W32.template: Update documentation for the current status
2563 of the MS-Windows port.
2564 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2565 environment variable is sometimes already defined which causes the
2567 * main.c (debug_signal_handler): Only define this function if
2568 SIGUSR1 is available.
2570 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2572 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2573 * README.OS2.template: Documentation updates.
2574 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2575 link line for safety.
2576 * maintMakefile (build.sh.in): Remove an extraneous ")".
2577 * job.c (child_execute_job): Close saved FDs.
2578 * job.c (exec_command) [OS/2]: exec_command(): If the command
2579 can't be exec'ed and if the shell is not Unix-sh, then try again
2580 with argv = { "cmd", "/c", ... }. Normally, this code is never
2581 reached for the cmd shell unless the command really doesn't exist.
2582 (construct_command_argv_internal) [OS/2]: The code for cmd
2583 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2584 The CMD builtin commands are case insensitive so use strcasecmp().
2586 2004-03-19 Paul D. Smith <psmith@gnu.org>
2588 * read.c (do_define): Re-order line counter increment so the count
2589 is accurate (we were losing one line per define). Reported by
2590 Dave Yost <Dave@Yost.com>.
2592 2004-03-06 Paul D. Smith <psmith@gnu.org>
2594 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2596 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2597 * misc.c (message,error,fatal): Ditto.
2598 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2599 * config.h.W32.template: Ditto.
2600 * config.h-vms.template: Ditto.
2601 * config.ami.template: Ditto.
2603 2004-03-04 Paul D. Smith <psmith@gnu.org>
2605 * README.template: Add a note about broken /bin/sh on SunOS
2606 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2608 * misc.c (message, error, fatal): Don't use "..." if we're using
2609 varargs. ansi2knr should handle this but it doesn't work: it
2610 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2611 done. On many systems (SunOS for example) va_dcl is a #define.
2612 So, force the use of the non-"..." version on pre-ANSI compilers.
2614 * maintMakefile (sign-dist): Create some rules to help automate
2615 the new GNU ftp upload method.
2617 2004-02-24 Paul D. Smith <psmith@gnu.org>
2619 * config.h.W32.template: Add HAVE_STDARG_H
2620 * config.h-vms.template: Ditto.
2621 * config.ami.template: Ditto.
2623 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2625 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2626 * build_w32.bat: Remove extra "+".
2628 2004-02-23 Paul D. Smith <psmith@gnu.org>
2630 * make.h: Create an UNUSED macro to mark unused parameters.
2631 * (many): Clean up warnings by applying UNUSED, fixing
2632 signed/unsigned incompatibilities, etc.
2634 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2636 * filedef.h: Name the command_state enumeration.
2637 * file.c (set_command_state): Use the enumeration in the function
2640 * configure.in: Explicitly set SET_MAKE to empty, to disable
2641 MAKE=make even when no make already exists. Fix bug #3823.
2643 2004-02-22 Paul D. Smith <psmith@gnu.org>
2645 * maintMakefile: Perl script to clean up all non-CVS files. Use
2646 it on all the subdirectories for the cvs-clean target.
2648 * main.c (decode_switches): Require non-empty strings for all our
2649 string command-line options. Fixes Debian bug # 164165.
2651 * configure.in: Check for stdarg.h and varargs.h.
2652 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2653 for printing messages.
2654 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2659 A number of patches for OS/2 support from Andreas Buening
2660 <andreas.buening@nexgo.de>:
2662 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2663 disable the SIGCHLD handler.
2664 (reap_children) [OS/2]: Remove special handling of job_rfd.
2665 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2666 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2667 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2668 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2669 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2672 2004-02-21 Paul D. Smith <psmith@gnu.org>
2674 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2675 <mail@kristov.de> reports that if process_begin() fails we don't
2676 handle the error condition correctly in all cases.
2677 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2678 to have a newline on the message.
2680 * job.c (construct_command_argv_internal): Add "test" to UNIX
2681 sh_cmds[]. Fixes Savannah bug # 7606.
2683 2004-02-04 Paul D. Smith <psmith@gnu.org>
2685 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2686 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2687 Hartmut Becker <Hartmut.Becker@hp.com>.
2689 2004-01-21 Paul D. Smith <psmith@gnu.org>
2691 * job.c (load_too_high): Implement an algorithm to control the
2692 "thundering herd" problem when using -l to control job creation
2693 via the load average. The system only recomputes the load once a
2694 second but we can start many jobs in a second. To solve this we
2695 keep track of the number of jobs started in the last second and
2696 apply a weight to try to guess what a correct load would be.
2697 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2698 Also fixes bug #4693.
2699 (reap_children): Decrease the job count for this second.
2700 (start_job_command): Increase the job count for this second.
2702 * read.c (conditional_line): Expand the text after ifn?def before
2703 checking to see if it's a single word. Fixes bug #7257.
2705 2004-01-09 Paul D. Smith <psmith@gnu.org>
2707 * file.c (print_file): Recurse to print all targets in
2708 double-colon rules. Fixes bug #4518, reported (with patch) by
2709 Andrew Chatham <chatham@google.com>.
2711 2004-01-07 Paul D. Smith <psmith@gnu.org>
2713 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2714 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2715 AC_FUNC_SETVBUF_REVERSED.
2717 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2718 (MAKE Variable): Fix Savannah bug #4898.
2720 * job.c (construct_command_argv_internal): Add "!" to the list of
2721 shell escape chars. POSIX sh allows it to appear before a
2722 command, to negate the exit code. Fixes bug #6404.
2724 * implicit.c (pattern_search): When matching an implicit rule,
2725 remember which dependencies have the ignore_mtime flag set.
2726 Original fix provided in Savannah patch #2349, by Benoit
2727 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2729 2003-11-22 Paul D. Smith <psmith@gnu.org>
2731 * README.W32.template (Outputs): Clarification on -j with
2732 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2735 2003-11-02 Paul D. Smith <psmith@gnu.org>
2737 * function.c (func_if): Strip all the trailing whitespace from the
2738 condition, then don't expand it. Fixed bug # 5798.
2740 * expand.c (recursively_expand_for_file): If we're expanding a
2741 variable with no file context, then use the variable's context.
2744 2003-10-21 Paul D. Smith <psmith@gnu.org>
2746 * main.c (log_working_directory): Add newlines to printf()s.
2748 * README.cvs: Add a note to ignore warnings during autoreconf.
2750 * maintMakefile (po_repo): Set a new URL for PO file updates.
2751 (get-config/config.guess get-config/config.sub): Get these files
2752 from the Savannah config project instead of ftp.gnu.org.
2754 2003-10-05 Paul Eggert <eggert@twinsun.com>
2756 * main.c (main): Avoid potential subscript error if environ has
2759 2003-08-22 Paul D. Smith <psmith@gnu.org>
2761 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2762 systems which don't yet implement the C89 standard :-/.
2764 2003-07-18 Paul D. Smith <psmith@gnu.org>
2766 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2767 [WINDOWS32]: Initialize hash.
2769 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2771 * dir.c (read_dirstream): Provide a workaround for broken versions of
2772 the MinGW dirent structure.
2774 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2776 * w32/include/dirent.h: Add __MINGW32__ filter.
2778 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2780 * make.h: Add global declaration of *make_host.
2781 * main.c (print_usage): Remove local declaration of *make_host.
2782 (print_version): Display "This program built for ..." after Copyright
2785 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2787 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2788 execution of "makeinfo --html make.texi".
2790 2003-04-30 Paul D. Smith <psmith@gnu.org>
2792 * build.template: Make some changes to maybe allow this script to
2793 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2795 * README.OS2.template: New file for OS/2 support. Original
2796 contributed by Andreas Buening.
2797 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2800 2003-04-19 Paul D. Smith <psmith@gnu.org>
2802 Fix bug #1405: allow a target to match multiple pattern-specific
2805 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2806 variable.c, where they've always belonged.
2807 * rule.h: Move the prototypes and struct pattern_var as well.
2808 * variable.c (initialize_file_variables): Invoke
2809 lookup_pattern_var() in a loop, until no more matches are found.
2810 If a match is found, create a new variable set for the target's
2811 pattern variables. Then merge the contents of each matching
2812 pattern variable set into the target's pattern variable set.
2813 (lookup_pattern_var): Change this function to be usable
2814 in a loop. It takes a starting position: if NULL, start at the
2815 beginning; if non-NULL, start with the pattern variable after that
2816 position, and return the next matching pattern.
2817 (create_pattern_var): Create a unique instance of
2818 pattern-specific variables for every definition in the makefile.
2819 Don't combine the same pattern together. This allows us to
2820 process the variable handling properly even when the same pattern
2821 is used multiple times.
2822 (parse_variable_definition): New function: break out the parsing
2823 of a variable definition line from try_variable_definition.
2824 (try_variable_definition): Call parse_variable_definition to
2826 (print_variable_data_base): Print out pattern-specific variables.
2827 * variable.h (struct variable): Remember when a variable is
2828 conditional. Also remember its flavor.
2829 (struct pattern_var): Instead of keeping a variable set, we just
2830 keep a single variable for each pattern.
2831 * read.c (record_target_var): Each pattern variable contains only a
2832 single variable, not a set, so create it properly.
2833 * doc/make.texi (Pattern-specific): Document the new behavior.
2835 2003-04-17 Paul D. Smith <psmith@gnu.org>
2837 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2838 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2839 file/directory naming rules for VMS so I can't tell whether this
2842 2003-04-09 Paul D. Smith <psmith@gnu.org>
2844 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2845 DOS-style pathnames: backslash separators and drive specifiers.
2847 2003-03-28 Paul D. Smith <psmith@gnu.org>
2849 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2850 the intermediate flag on all targets. Fixes bug #2515.
2852 2003-03-24 Paul D. Smith <psmith@gnu.org>
2854 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2855 Upgrade to autoconf 2.57 and automake 1.7.3.
2857 * job.c: More OS/2 changes from Andreas Buening.
2859 * file.c (print_file): Fix variable initialization.
2862 * remake.c (notice_finished_file):
2864 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2865 some calls (like readdir()) return NULL in valid situations
2866 without resetting errno. Fixes bug #2846.
2868 2003-02-25 Paul D. Smith <psmith@gnu.org>
2870 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2872 * job.c (_is_unixy_shell) [OS/2]: New function.
2873 Set default shell to /bin/sh.
2874 (reap_children): Close the job_rfd pipe here since we don't use a
2876 (set_child_handler_action_flags): define this to empty on OS/2.
2877 (start_job_command): Close the jobserver pipe and use
2878 child_execute_job() instead of fork/exec.
2879 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2880 rather than exec'ing, then reconfigure stdin/stdout.
2881 (exec_command): Rewrite to use spawn instead of exec. Return the
2884 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2885 in DOS. Handle the TEMP environment variable as in DOS. Don't
2886 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2887 use -j in DOS mode. Use child_execute_job() instead of
2890 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2893 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2894 prototypes that return values.
2896 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2898 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2899 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2901 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2904 2003-02-24 Paul D. Smith <psmith@gnu.org>
2906 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2907 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2908 (child_execute_job) [VMS]: Handle error status properly.
2909 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2911 * function.c (func_shell): Use EINTRLOOP() while reading from the
2912 subshell pipe (Fixes bug #2502).
2913 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2915 * main.c (main): Ditto.
2917 2003-01-30 Paul D. Smith <psmith@gnu.org>
2919 * read.c (eval): eval() was not fully reentrant, because the
2920 collapsed buffer was static. Change it to be an automatic
2921 variable so that eval() can be invoked recursively.
2923 (eval): Apply patch # 1022: fix memory reference error on long
2924 target-specific variable lines.
2925 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2927 * function.c (check_numeric): Combine the is_numeric() function
2928 into this function, since it's only called from one place.
2929 Constify this function. Have it print the incorrect string in the
2930 error message. Fixes bug #2407.
2931 (strip_whitespace): Constify.
2932 (func_if): Constify.
2933 * expand.c (expand_argument): Constify.
2935 2003-01-29 Paul D. Smith <psmith@gnu.org>
2937 Fix bug # 2169, also reported by other people on various systems.
2939 * make.h: Some systems, such as Solaris and PTX, do not fully
2940 implement POSIX-compliant SA_RESTART functionality; important
2941 system calls like stat() and readdir() can still fail with EINTR
2942 even if SA_RESTART has been set on the signal handler. So,
2943 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2944 EINTR for system calls which return -1 or 0 (NULL), respectively,
2946 Also, remove the old atomic_stat()/atomic_readdir() and
2947 HAVE_BROKEN_RESTART handling.
2949 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2951 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2952 * remake.c (touch_file): Ditto.
2954 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2955 * read.c (construct_include_path): Ditto.
2956 * remake.c (name_mtime): Ditto.
2957 * vpath.c (selective_vpath_search): Ditto.
2958 * dir.c (find_directory): Ditto.
2959 (local_stat): Ditto.
2960 (find_directory): Use ENULLLOOP() to wrap opendir().
2961 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2963 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2964 atomic_readdir() handling.
2966 2003-01-22 Paul D. Smith <psmith@gnu.org>
2968 * function.c (func_call): Fix Bug #1744. If we're inside a
2969 recursive invocation of $(call ...), mask any of the outer
2970 invocation's arguments that aren't used by this one, so that this
2971 invocation doesn't "inherit" them accidentally.
2973 2002-12-05 Paul D. Smith <psmith@gnu.org>
2975 * function.c (subst_expand): Valery Khamenia reported a
2976 pathological performance hit when doing substitutions on very
2977 large values with lots of words: turns out we were invoking
2978 strlen() a ridiculous number of times. Instead of having each
2979 call to sindex() call strlen() again, keep track of how much of
2980 the text we've seen and pass the length to sindex().
2982 2002-11-19 Paul D. Smith <psmith@gnu.org>
2984 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2987 2002-11-16 Paul D. Smith <psmith@gnu.org>
2989 * NMakefile.template (OBJS): Add hash.c object file.
2990 * SMakefile.template (srcs): Ditto.
2991 * Makefile.ami (objs): Ditto.
2992 * build_w32.bat: Ditto.
2994 * Makefile.DOS.template: Remove extra dependencies.
2996 2002-10-25 Paul D. Smith <psmith@gnu.org>
2998 * expand.c (install_variable_buffer): New function. Install a new
2999 variable_buffer context and return the previous one.
3000 (restore_variable_buffer): New function. Free the current
3001 variable_buffer context and put a previously saved one back.
3002 * variable.h: Prototypes for {install,restore}_variable_buffer.
3003 * function.c (func_eval): Push a new variable_buffer context
3004 before we eval, then restore the old one when we're done.
3007 * read.c (install_conditionals): New function. Install a new
3008 conditional context and return the previous one.
3009 (restore_conditionals): New function. Free the current
3010 conditional context and put a previously saved one back.
3011 (eval): Use the {install,restore}_conditionals for "include"
3013 (eval_buffer): Use {install,restore}_conditionals to preserve the
3014 present conditional state before we evaluate the buffer.
3017 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3019 (Recursion): Add a variable index entry for CURDIR.
3021 * README.cvs: Update to appropriate versions.
3022 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3023 don't need to copy loadavg.c: automake is smart enough to create
3024 it for me. Still have a bug in automake related to ansi2knr tho.
3026 2002-10-14 Paul D. Smith <psmith@gnu.org>
3028 * remake.c (notice_finished_file): Only touch targets if they have
3029 at least one command (as per POSIX). Resolve Bug #1418.
3031 * *.c: Convert to using ANSI C-style function definitions.
3032 * Makefile.am: Enable the ansi2knr feature of automake.
3033 * configure.in: ditto.
3035 2002-10-13 Paul D. Smith <psmith@gnu.org>
3037 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3038 for automatic variable values like $^, etc. In the case of very
3039 large lists of prerequisites this causes problems. Instead reuse
3040 a static buffer (resizeable) for each variable.
3042 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3043 target-specific variable definitions. Check for it and set an
3045 (record_target_var): Set the export field to v_export if the
3046 "exported" flag is set.
3047 * doc/make.texi (Target-specific): Document the ability to use
3050 * doc/make.texi: Change the name of the section on automatic
3051 variables from "Automatic" to "Automatic Variables". Added text
3052 clarifying the scope of automatic variables.
3054 2002-10-04 Paul D. Smith <psmith@gnu.org>
3056 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3058 (record_files): Ditto.
3060 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3061 the search for the '=' to only within the enclosing parens.
3063 2002-10-03 Paul D. Smith <psmith@gnu.org>
3065 Version 3.80 released.
3067 * dir.c: Change hash functions to use K&R function definition style.
3068 * function.c: Ditto.
3070 * variable.c: Ditto.
3072 Update to automake 1.7.
3074 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3075 (pdf): Remove this target as automake now provides one.
3077 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3079 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3081 * makefile.com: Updates for GNU make 3.80.
3082 * makefile.vms: Ditto.
3084 2002-09-23 Paul D. Smith <psmith@gnu.org>
3086 * read.c (enum make_word_type): Remove w_comment.
3087 (get_next_mword): Don't treat comment characters as special; where
3088 this function is used we will never see a comment (it's stripped
3089 before we get here) and treating comments specially means that
3090 targets like "foo\#bar" aren't handled properly.
3092 2002-09-18 Paul D. Smith <psmith@gnu.org>
3094 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3096 * read.c (eval): Expansion of arguments to export/unexport was
3097 ignoring all arguments after the first one. Change the algorithm
3098 to expand the whole line once, then parse the results.
3100 2002-09-17 Paul D. Smith <psmith@gnu.org>
3102 Fix Bug #940 (plus another bug I found while looking at this):
3104 * read.c (record_target_var): enter_file() will add a new entry if
3105 it's a double-colon target: we don't want to do that in this
3106 situation. Invoke lookup_file() and only enter_file() if it does
3107 not already exist. If the file we get back is a double-colon then
3108 add this variable to the "root" double-colon target.
3110 * variable.c (initialize_file_variables): If this file is a
3111 double-colon target but is not the "root" target, then initialize
3112 the root and make the root's variable list the parent of our
3115 2002-09-13 Paul D. Smith <psmith@gnu.org>
3117 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3119 * hash.c (round_up_2): Get rid of a warning.
3121 2002-09-12 Paul D. Smith <psmith@gnu.org>
3123 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3124 so it doesn't complain about getloadavg.c.
3126 * commands.c (set_file_variables): Make sure we always alloca() at
3127 least 1 character for the value of $? (for '\0').
3129 2002-09-11 Paul D. Smith <psmith@gnu.org>
3131 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3132 macro to use RESULT instead of the incorrect _RESULT_.
3134 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3135 and atomic_readdir(). We need to #include dirent.h to get this to
3137 * misc.c (atomic_readdir): Fix typos.
3139 2002-09-10 Paul D. Smith <psmith@gnu.org>
3141 * read.c (eval): Expand variable lists given to export and
3142 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3143 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3145 * doc/make.texi (Variables/Recursion): Document this.
3146 (Conditional Syntax): And here.
3148 2002-09-09 Paul D. Smith <psmith@gnu.org>
3150 * configure.in: Check for memmove().
3152 2002-09-07 Paul D. Smith <psmith@gnu.org>
3154 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3155 Michael Sterrett <msterret@coat.com> reports that while it has
3156 SA_RESTART, it does not work properly.
3158 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3159 that invokes stat() and loops to do it again if it returns EINTR.
3160 (atomic_readdir): Ditto, with readdir().
3162 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3163 and readdir() to atomic_stat() and atomic_readdir().
3165 2002-09-04 Paul D. Smith <psmith@gnu.org>
3167 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3168 reports that GNU make sometimes doesn't recognize that targets can
3169 be made, when directories can be created as prerequisites. He
3170 reports that changing the order of predicates in the DEP->changed
3171 flag test so that lookup_file() is always performed, solves this
3174 2002-08-08 Paul D. Smith <psmith@gnu.org>
3176 * configure.in: Require a newer version of gettext.
3178 * misc.c (perror_with_name): Translate the format string (for
3179 right-to-left language support).
3180 (pfatal_with_name): Ditto.
3182 * main.c: Create a static array of strings to store the usage
3183 text. This is done to facilitate translations.
3184 (struct command_switch): Remove argdesc and description fields.
3185 (switches): Remove values for obsolete fields.
3186 (print_usage): Print each element of the usage array.
3188 * hash.c: Change function definitions to be K&R style.
3190 2002-08-02 Paul D. Smith <psmith@gnu.org>
3192 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3193 this one because it's too hard to get right. We'll look at it for
3195 * main.c (main): Don't create the .TARGETS variable.
3196 * variable.c (handle_special_var): Don't handle .TARGETS.
3198 2002-08-01 Paul D. Smith <psmith@gnu.org>
3200 * main.c (switches): Add a new option, -B (--always-make). If
3201 specified, make will rebuild all targets that it encounters even
3202 if they don't appear to be out of date.
3203 (always_make_flag): New flag.
3204 * make.h: Extern always_make_flag.
3205 * remake.c (update_file_1): Check always_make_flag; if it's set we
3206 will always rebuild any target we can, even if none of its
3207 prerequisites are newer.
3210 * doc/make.texi (Shell Function): Make it clear that make
3211 variables marked as "export" are not passed to instances of the
3214 Add new introspection variable .VARIABLES and .TARGETS.
3216 * variable.c (handle_special_var): New function. If the variable
3217 reference passed in is "special" (.VARIABLES or .TARGETS),
3218 calculate the new value if necessary. .VARIABLES is handled here:
3219 walk through the hash of defined variables and construct a value
3220 which is a list of the names. .TARGETS is handled by
3221 build_target_list().
3222 (lookup_variable): Invoke handle_special_var().
3223 * file.c (build_target_list): Walk through the hask of known files
3224 and construct a list of the names of all the ones marked as
3226 * main.c (main): Initialize them to empty (and as simple variables).
3227 * doc/make.texi (Special Variables): Document them.
3228 * NEWS: Mention them.
3230 * variable.h (struct variable): Add a new flag "exportable" which
3231 is true if the variable name is valid for export.
3232 * variable.c (define_variable_in_set): Set "exportable" when a new
3233 variable is defined.
3234 (target_environment): Use the "exportable" flag instead of
3235 re-checking the name here... an efficiency improvement.
3237 2002-07-31 Paul D. Smith <psmith@gnu.org>
3239 * config.h-vms.template: Updates to build on VMS. Thanks to
3240 Brian_Benning@aksteel.com for helping verify the build.
3241 * makefile.com: Build the new hash.c file.
3242 * hash.h: Use strcpmi(), not stricmp(), in the
3243 HAVE_CASE_INSENSITIVE_FS case.
3245 2002-07-30 Paul D. Smith <psmith@gnu.org>
3247 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3248 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3249 Reported by <Brian_Benning@aksteel.com>.
3251 2002-07-10 Paul D. Smith <psmith@gnu.org>
3253 * variable.c (pop_variable_scope): Remove variable made unused by
3254 new hash infrastructure.
3255 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3256 comparisons as well as name comparisons.
3257 * variable.h: Add a prototype for new hash_init_function_table().
3258 * file.c (lookup_file): Remove variables made unused by new hash
3260 * dir.c (directory_contents_hash_2): Missing return of hash value.
3261 (dir_contents_file_exists_p): Remove variables made unused by new
3262 hash infrastructure.
3265 Installed Greg McGary's integration of the hash functions from the
3266 GNU id-utils package:
3268 2002-07-10 Greg McGary <greg@mcgary.org>
3270 * scripts/functions/filter-out: Add literals to to the
3271 pattern space in order to add complexity, and trigger
3272 use of an internal hash table. Fix documentation strings.
3273 * scripts/targets/INTERMEDIATE: Reverse order of files
3274 passed to expected `rm' command.
3276 2002-07-10 Greg McGary <greg@mcgary.org>

3335 (struct a_pattern): New struct.
3336 (func_filter_filterout): Pass through patterns noting boundaries
3337 and '%', if present. Note a_word length. Use a hash table if
3338 arglists are large enough to justify cost.

3348 (find_char_unquote): Accept two char-constant stop chars, rather
3349 than a string constant, avoiding zillions of calls to strchr.
3350 Tighten inner search loops to test only for desired delimiters.

3368 2002-07-10 Paul D. Smith <psmith@gnu.org>
3370 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3371 prerequisite list. A real SysV make will expand the entire
3372 prerequisites list _twice_: we don't do that as it's a big
3373 backward-compatibility problem. We only replace those specific
3376 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3377 references left in the list of prerequisites. Check for .POSIX as
3378 we record targets, so we can disable non-POSIX behavior while
3379 reading makefiles as well as running them.
3380 (eval): Check the prerequisite list to see if we have anything
3381 that looks like a SysV prerequisite variable reference.
3383 2002-07-09 Paul D. Smith <psmith@gnu.org>
3385 * doc/make.texi (Prerequisite Types): Add a new section describing
3386 order-only prerequisites.
3388 * read.c (uniquize_deps): If we have the same file as both a
3389 normal and order-only prereq, get rid of the order-only prereq,
3390 since the normal one supersedes it.
3392 2002-07-08 Paul D. Smith <psmith@gnu.org>
3394 * AUTHORS: Added Greg McGary to the AUTHORS file.
3395 * NEWS: Blurbed order-only prerequisites.
3396 * file.c (print_file): Show order-only deps properly when printing
3399 * maintMakefile: Add "update" targets for wget'ing the latest
3400 versions of various external files. Taken from Makefile.maint in
3403 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3404 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3406 2002-07-07 Paul D. Smith <psmith@gnu.org>
3408 * po/*.po: Remove. We'll use wget to retrieve them at release
3411 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3412 rather than a shell you get an exception. Make sure we look up
3413 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3415 * remake.c (notice_finished_file): Fix handling of -t flag.
3416 Patch provided by Henning Makholm <henning@makholm.net>.
3418 * implicit.c (pattern_search): Some systems apparently run short
3419 of stack space, and using alloca() in this function caused an
3420 overrun. I modified it to use xmalloc() on the two variables
3421 which seemed like they might get large. Fixes Bug #476.
3423 * main.c (print_version): Update copyright notice to conform with
3425 (print_usage): Update help output.
3427 * function.c (func_eval): Create a new make function, $(eval
3428 ...). Expand the arguments, put them into a buffer, then invoke
3429 eval_buffer() on the resulting string.
3430 (func_quote): Create a new function, $(quote VARNAME). Inserts
3431 the value of the variable VARNAME without expanding it any
3434 * read.c (struct ebuffer): Change the linebuffer structure to an
3435 "eval buffer", which can be either a file or a buffer.
3436 (eval_makefile): Move the code in the old read_makefile() which
3437 located a makefile into here: create a struct ebuffer with that
3438 information. Have it invoke the new function eval() with that
3440 (eval_buffer): Create a new function that creates a struct ebuffer
3441 that holds a string buffer instead of a file. Have it invoke
3442 eval() with that ebuffer.
3443 (eval): New function that contains the guts of the old
3444 read_makefile() function: this function parses makefiles. Obtains
3445 data to parse from the provided ebuffer. Some modifications to
3446 make the flow of the function cleaner and clearer. Still could
3447 use some work here...
3448 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3449 contents of the define/endef variable from the ebuffer.
3450 (readstring): Read the next line from a string-style ebuffer.
3451 (readline): Read the next line from an ebuffer. If it's a string
3452 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3455 * dep.h (eval_buffer): Prototype eval_buffer();
3457 * variable.c (do_variable_definition): Make sure that all
3458 non-target-specific variables are registered in the global set.
3459 If we're invoked from an $(eval ...) we might be inside a $(call
3460 ...) or other function which has pushed a variable scope; we still
3461 want to define our variables from evaluated makefile code in the
3464 2002-07-03 Greg McGary <greg@mcgary.org>
3466 * dep.h (struct dep) [ignore_mtime]: New member.
3467 [changed]: convert to a bitfield.
3468 * implicit.c (pattern_search): Zero ignore_mtime.
3469 * main.c (main, handle_non_switch_argument): Likewise.
3470 * rule.c (convert_suffix_rule): Likewise.
3471 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3472 (read_makefile): Parse '|' in prerequisite list.
3473 (uniquize_deps): Consider ignore_mtime when comparing deps.
3474 * remake.c (update_file_1, check_dep): Don't force remake for
3475 dependencies that have d->ignore_mtime.
3476 * commands.c (FILE_LIST_SEPARATOR): New constant.
3477 (set_file_variables): Don't include a
3478 prerequisite in $+, $^ or $? if d->ignore_mtime.
3481 2002-06-18 Paul D. Smith <psmith@gnu.org>
3483 * make.texinfo: Updates for next revision. New date/rev/etc.
3484 Recreate all Info menus. Change license on the manual to the GNU
3485 Free Documentation License. A number of typos.
3486 (Variables Simplify): Don't use "-" before it's defined.
3487 (Automatic Prerequisites): Rewrite the target example to work
3488 properly if the compile fails. Remove incorrect comments about
3489 how "set -e" behaves.
3490 (Text Functions): Move the "word", "wordlist", "words", and
3491 "firstword" functions here, from "File Name Functions".
3492 * make-stds.texi: Update from latest GNU version.
3493 * fdl.texi: (created) Import the latest GNU version.
3495 2002-06-06 Paul D. Smith <psmith@gnu.org>
3497 * variable.c (do_variable_definition): New function: extract the
3498 part of try_variable_definition() that actually sets the value
3499 into a separate function.
3500 (try_variable_definition): Call do_variable_definition() after
3501 parsing the variable definition string.
3502 (define_variable_in_set): Make the name argument const.
3504 * variable.h (enum variable_flavor): Make public.
3505 (do_variable_definition): Create prototype.
3507 * read.c (read_all_makefiles): Create a new built-in variable,
3509 (read_makefile): Add each makefile read in to this variable value.
3511 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3513 * Makefile.DOS.template: Tweak according to changes in the
3514 distribution. Add back the dependencies of *.o files.
3516 * configh.dos.template: Synchronize with config.h.in.
3518 2002-05-09 Paul D. Smith <psmith@gnu.org>
3520 * file.c (file_timestamp_now): Use K&R function declaration.
3522 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3523 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3524 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3525 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3526 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3527 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3528 nlist.n_name is a pointer rather than an array.
3530 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3531 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3532 * configure.in: Use it instead of the old version.
3534 * main.c (main): Prefer setvbuf() to setlinebuf().
3536 2002-05-08 Paul D. Smith <psmith@gnu.org>
3538 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3539 (loadavg_LDADD): Ditto.
3541 2002-04-29 Paul D. Smith <psmith@gnu.org>
3543 * expand.c (recursively_expand_for_file): Rename
3544 recursively_expand() to recursively_expand_for_file() and provide
3545 an extra argument, struct file. If the argument is provided, set
3546 the variable scope to that of the file before expanding.
3547 * variable.h (recursively_expand): Make this a macro that invokes
3548 recursively_expand_for_file() with a NULL file pointer.
3549 * variable.c (target_environment): Call the renamed function and
3550 provide the current file context.
3551 Fixes Debian bug #144306.
3553 2002-04-28 Paul D. Smith <psmith@gnu.org>
3555 Allow $(call ...) user-defined variables to be self-referencing
3556 without throwing an error. Allows implementation of transitive
3557 closures, among other possibly useful things.
3558 Requested by: Philip Guenther <guenther@sendmail.com>
3560 * variable.h (struct variable): Add a new field: exp_count, and
3561 new macros to hold its size and maximum value.
3562 (warn_undefined): Make this a macro.
3563 * variable.c (define_variable_in_set): Initialize it.
3564 * expand.c (recursively_expand): If we detect recursive expansion
3565 of a variable, check the exp_count field. If it's greater than 0
3566 allow the recursion and decrement the count.
3567 (warn_undefined): Remove this (now a macro in variable.h).
3568 * function.c (func_call): Before we expand the user-defined
3569 function, modify its exp_count field to contain the maximum
3570 number of recursive calls we'll allow. After the call, reset it
3573 2002-04-21 Paul D. Smith <psmith@gnu.org>
3575 Modified to use latest autoconf (2.53), automake (1.6.1), and
3576 gettext (0.11.1). We're using gettext's new "external" support,
3577 to avoid including libintl source with GNU make.
3579 * README.cvs: New file. Explain how to build GNU make from CVS.
3581 * configure.in: Modify checking for the system glob library.
3582 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3583 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3584 etc. will manage it correctly). Set an automake conditional
3585 USE_LOCAL_GLOB to decide whether to compile the glob library.
3587 * getloadavg.c (main): Include make.h in the "TEST" program to
3590 * Makefile.am: Remove special rules for loadavg. Replace them
3591 with Automake capabilities for building extra programs.
3593 * signame.c: This file does nothing if the system provide
3594 strsignal(). If not, it implements strsignal(). If the system
3595 doesn't define sys_siglist, then we make our own; otherwise we use
3597 * signame.h: Removed.
3599 * main.c (main): No need to invoke signame_init(). Update copyright.
3601 * ABOUT-NLS: Removed.
3602 * gettext.c: Removed.
3603 * gettext.h: Get a simplified copy from the gettext package.
3605 * i18n/*.po: Moved to po/.
3608 * config/*: Created. Contains package configuration helper files.
3609 * config.guess, config.sub: Moved to config directory.
3611 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3612 Rework to use new-style autoconf features. Use the "external"
3613 mode for gettext. Make the build.sh config file conditional on
3614 whether build.sh.in exists, to avoid autoconf errors.
3615 * acinclude.m4: Removed almost all macros as being obsolete.
3616 Rewrote remaining macros to use AC_DEFINE.
3617 * acconfig.h: Removed.
3619 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3620 conditional to handle customs support. Remove special handling
3623 2002-04-20 Paul D. Smith <psmith@gnu.org>
3625 * function.c (func_call): Don't mark the argument variables $1,
3626 etc. as recursive. They've already been fully expanded so
3627 there's no need to do it again, and doing so strips escaped $'s.
3628 Reported by Sebastian Glita <glseba@yahoo.com>.
3630 * remake.c (notice_finished_file): Walk through double-colon
3631 entries via the prev field, not the next field!
3632 Reported by Greg McGary <greg@mcgary.org>.
3634 * main.c (main): If the user specifies -q and asks for a specific
3635 target which is a makefile, we got an assert. In that case it
3636 turns out we should continue normally instead.

3675 * i18n/ko.po: Installed a new translation.
3677 2001-05-06 Paul D. Smith <psmith@gnu.org>
3679 Modify the EINTR handling.
3681 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3682 the way in which we manage the file descriptor/signal handler race
3683 trap to be more efficient.
3685 2001-05-06 Paul Eggert <eggert@twinsun.com>
3687 Restart almost all system calls that are interrupted, instead
3688 of worrying about EINTR. The lone exception is the read() for
3691 * configure.in (HAVE_SA_RESTART): New macro.
3692 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3693 * main.c (main): Use SA_RESTART instead of the old,
3694 nonstandard SA_INTERRUPT.
3696 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3697 * main.c (bsd_signal): New function or macro,
3698 if the implementation doesn't supply it.
3699 (The bsd_signal function will be in POSIX 1003.1-200x.)
3700 (HANDLESIG): Remove.
3701 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3703 * make.h (EINTR_SET): Remove.
3704 (SA_RESTART): New macro.
3706 * arscan.c (ar_member_touch): Don't worry about EINTR.
3707 * function.c (func_shell): Likewise.
3708 * job.c (reap_children, free_child, new_job): Likewise.
3709 * main.c (main): Likewise.
3710 * remake.c (touch_file, name_mtime): Likewise.
3712 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3713 if fstat failed with errno!=EINTR, the error was ignored.
3715 * job.c (set_child_handler_action_flags): New function.
3716 (new_job): Use it to temporarily clear the SIGCHLD action flags
3717 while reading the token.
3719 2001-05-02 Paul D. Smith <psmith@gnu.org>
3721 * job.c (start_job_command): Don't add define/endef per-line flags
3722 to the top-level flags setting.
3724 2001-04-03 Paul D. Smith <psmith@gnu.org>
3726 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3727 bit on error, so check for odd return values, not non-0 return
3729 (VMS_get_member_info): Calculate the timezone differences correctly.
3730 Reported by John Fowler <jfowler@nyx.net>.
3733 2001-03-14 Paul D. Smith <psmith@gnu.org>
3735 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3736 value before invoking define_variable().
3737 Reported by John Fowler <jfowler@nyx.net>.
3739 2001-02-07 Paul D. Smith <psmith@gnu.org>
3741 * read.c (record_target_var): If we reset the variable due to a
3742 command-line variable setting overriding it, turn off the "append"
3745 2001-01-17 Paul D. Smith <psmith@gnu.org>
3747 * variable.c (lookup_variable) [VMS]: When getting values from the
3748 environment, allocate enough space for the _value_ plus escapes,
3749 not enough space for the name plus escapes :-/.
3750 Reported by John Fowler <jfowler@nyx.net>.
3752 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3753 warnings that make generates, so it doesn't look like an error.
3754 Reported by Karl Berry <karl@gnu.org>.
3757 Fix for PR/2020: Rework appended target-specific variables. I'm
3758 fairly confident this algorithm is finally correct.
3760 * expand.c (allocated_variable_append): Rewrite. Instead of
3761 expanding each appended variable then adding all the expanded
3762 strings together, we append all the unexpanded values going up
3763 through the variable set contexts, then expand the final result.
3764 This behaves just like non-target-specific appended variable
3765 values, while the old way didn't in various corner cases.
3766 (variable_append): New function: recursively append the unexpanded
3767 value of a variable, walking from the outermost variable scope to
3769 * variable.c (lookup_variable): Remove the code that looked up the
3770 variable set list if the found variable was "append". We don't
3772 (lookup_variable_in_set): Make this non-static so we can use it
3774 (try_variable_definition): Use lookup_variable_in_set() rather
3775 than faking out current_variable_set_list by hand (cleanup).
3776 * variable.h: Add a prototype for the now non-static
3777 lookup_variable_in_set().
3779 2000-11-17 Paul D. Smith <psmith@gnu.org>
3781 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3782 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3783 before throwing a fit.
3785 2000-11-17 Paul D. Smith <psmith@gnu.org>
3787 * read.c (readline): CRLF calculations had a hole, if you hit the
3788 buffer grow scenario just right. Reworked the algorithm to avoid
3789 the need for len or lastlen at all. Problem description with
3790 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3792 2000-10-24 Paul D. Smith <psmith@gnu.org>
3794 * gettext.c (SWAP): Declare this with the prototype, otherwise
3795 some systems don't work (non-32-bit? Reported for Cray T3E).
3796 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3798 2000-10-05 Paul D. Smith <psmith@gnu.org>
3800 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3801 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3803 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3805 2000-09-22 Paul D. Smith <psmith@gnu.org>
3807 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3808 parts of the real gettext.h here, and we expect to really include
3809 the real gettext.h later. If we keep this #define, it's ignored.
3811 2000-09-21 Paul D. Smith <psmith@gnu.org>
3813 * main.c (log_working_directory): Rework the text to use complete
3814 sentences, to make life simpler for the translators.
3816 2000-08-29 Paul D. Smith <psmith@gnu.org>
3818 * file.c (remove_intermediates): Print a debug message before we
3819 remove intermediate files, so the user (if she uses -d) knows
3822 2000-08-21 Paul D. Smith <psmith@gnu.org>
3824 * variable.c (try_variable_definition): Change how we handle
3825 target-specific append variable defns: instead of just setting the
3826 value, expand it as an append _but_ only within the current
3827 target's context. Otherwise we lose all but the last value if the
3828 variable is appended more than once within the current target
3829 context. Fixes PR/1831.
3831 2000-08-16 Paul D. Smith <psmith@gnu.org>
3833 * function.c (func_shell): Nul-terminate the buffer before
3834 printing an exec error message (just in case it's not!).
3835 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3837 2000-07-25 Paul D. Smith <psmith@gnu.org>
3839 * job.c (construct_command_argv_internal): Add "~" to the list of
3840 sh_chars[] which disallow optimizing out the shell call.
3842 2000-07-23 Paul Eggert <eggert@twinsun.com>
3844 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3845 supersedes --disable-nsec-timestamps.
3846 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3847 * README: Remove --disable-nsec-timestamps.
3849 * filedef.h (struct file.low_resolution_time): New member.
3850 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3851 * remake.c (update_file_1):
3852 Avoid spurious rebuilds due to low resolution time stamps,
3853 generalizing the earlier code that applied only to archive members.
3854 (f_mtime): Archive members always have low resolution time stamps.
3856 * configure.in: Remove --disable-nsec-timestamps, as this has
3857 been superseded by .LOW_RESOLUTION_TIME.
3859 2000-07-23 Paul Eggert <eggert@twinsun.com>
3861 * configure.in (enable_nsec_timestamps): Renamed from
3862 make_cv_nsec_timestamps, since enable/disable options
3863 shouldn't be cached.
3865 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3866 and Paul Eggert <eggert@twinsun.com>
3868 * file.c (file_timestamp_now):
3869 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3870 so that clock_gettime is not linked unless needed.
3872 * filedef.h (FILE_TIMESTAMP_HI_RES):
3873 Remove definition; "configure" now does this.
3875 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3876 to before high resolution file timestamp check,
3877 since that check now uses uintmax_t.
3878 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3879 high resolution file timestamps.
3880 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3881 so that we don't link in clock_gettime unnecessarily.
3883 2000-07-17 Paul D. Smith <psmith@gnu.org>
3885 * i18n/ja.po: New version of the translation file.
3887 2000-07-07 Paul D. Smith <psmith@gnu.org>
3889 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3890 the offset calculation.
3891 (name_mtime): Replace EINTR test with EINTR_SET macro.
3893 2000-07-07 Paul Eggert <eggert@twinsun.com>
3897 * remake.c (update_file_1):
3898 Avoid spurious rebuilds of archive members due to their
3899 timestamp resolution being only one second.
3900 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3901 the clock's resolution being lower than file timestamps'.
3902 When warning about future timestamps, report only the discrepancy,
3903 not the absolute value of the timestamp and the current time.
3905 * file.c (file_timestamp_now): New arg RESOLUTION.
3906 * filedef.h (file_timestamp_now): Likewise.
3907 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3909 2000-07-05 Paul D. Smith <psmith@gnu.org>
3911 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3912 to listp. Fixes PR/1793.
3914 2000-06-26 Paul Eggert <eggert@twinsun.com>
3916 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3918 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3920 * remake.c (f_mtime): Remove unused var memtime.
3922 2000-06-25 Martin Buchholz <martin@xemacs.org>
3924 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3925 Ran spell-check on make.texinfo.
3927 2000-06-23 Paul D. Smith <psmith@gnu.org>
3929 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3930 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3931 * make.h: Define these macros.
3933 * Version 3.79.1 released.
3935 * configure.in: Add a new option, --disable-nsec-timestamps, to
3936 avoid using sub-second timestamps on systems that support it. It
3937 can lead to problems, e.g. if your makefile relies on "cp -p".
3938 * README.template: Document the issue with "cp -p".
3940 * config.guess, config.sub: Updated.
