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

86 lowest directory index.
88 * implicit.c (pattern_search): Pass NULL for the index arguments in
89 the VPATH_SEARCH call.
91 * doc/make.texi (Directory Search for Link Libraries): Describe the

102 indeterminately.
104 2009-10-24 Paul Smith <psmith@gnu.org>
106 * main.c (usage): Add --eval to the usage string.
107 (switches): Add the --eval switch.
108 (main): If --eval is given, add them to the simply-expanded variable

148 * read.c (uniquize_deps): Merge into set_file_variables in
149 commands.c.
150 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
152 * commands.c (set_file_variables): Avoid modifying the dep
153 chain to achieve uniqueness. Fixes savannah bug 25780.
155 * implicit.c (pattern_search): Instead of re-setting all automatic
156 variables for each rule we try, just update $*.
158 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>

179 if we need to parse a rule that requires the second expansion.
181 2009-10-03 Paul Smith <psmith@gnu.org>
183 * make.h: Include <alloca.h> even on systems where __GNUC__ is
184 defined. Not sure why it was done the other way.
185 Requested by David Boyce <dsb@boyski.com>.
187 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>

191 * filedef.h (file):Add the NO_DIAG bitfield.
193 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
194 not struct file (a file can be a dependency of many targets,
195 some don't care, some do).
197 * remake.c (update_goal_chain): Propagate DONTCARE from struct
198 dep to struct file before updating the goal and restore it
199 afterwards.
200 (update_file): Don't prune the dependency graph if this target
201 has failed but the diagnostics hasn't been issued.
202 (complain): Scan the file's dependency graph to find the file
203 that caused the failure.
204 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
205 whether to print diagnostics.

222 * varible.c (create_pattern_var): Insert variables into the
223 PATTERN_VARS list in the shortest patterns first order.

243 double-colons have a different meaning. Savannah bug #27497.
245 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
247 * configh.dos.template: Remove unconditional definition of
248 SYS_SIGLIST_DECLARED.
249 Include <sys/version.h> because ports of GCC 4.3.0 and later no
250 longer include it, so macros like __DJGPP_MINOR__ are no longer
251 defined automatically.
253 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
254 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
255 instead of using the hardcoded ones.
256 (SUBDIRS): doc subdir added.
257 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
258 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
259 create html formated docs. texi2html may not be ported to DOS.
260 (make.info, make.dvi, make.ps, make.html): Make targets depend on
261 'make.texi'.
262 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
263 -I switch to look in ./ instead of ./doc.
264 (html): Target depend on html-recursive instead of make_1.html.
265 (make_1.html): Removed.

270 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
271 (tags-recursive): Allow for more than one subdir in the build
272 process.
273 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
274 targets. Enter into doc/ to produce the targets.
275 (all-am): $(INFO_DEPS) replaced by info.
277 2009-09-26 Paul Smith <psmith@gnu.org>
279 * read.c (record_files): Use free_ns() to free struct nameseq.
280 (eval): Ditto.
282 * rule.c (freerule): Use free_dep_chain().
284 * read.c (record_files): Free FILENAMES chain for implicit rules.
285 (eval): Static pattern targets go into the string cache.
287 * function.c (string_glob): Free NAME in the nameseq chain.
289 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
291 * implicit.c (pattern_search): Terminate early if we haven't
292 found any rules to try (performance improvement).
294 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
296 * implicit.c (pattern_search): Merge three parallel arrays,
297 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
298 of struct TRYRULE. In the old version the latter two arrays
299 had insufficient length.
301 2009-09-24 Paul Smith <psmith@gnu.org>
303 * implicit.c (pattern_search): Add back support for order-only
304 prerequisites for secondary expansion implicit rules, that were
305 accidentally dropped. If we find a "|", enable order-only mode
306 and set IGNORE_MTIME on all deps that are seen afterward.
307 (pattern_search): Fix memory leaks: for intermediate files where
308 we've already set the file variable and pattern variable sets, be
309 sure to either save or free them as appropriate.
311 2009-09-23 Paul Smith <psmith@gnu.org>
313 Rework the way secondary expansion is stored, for efficiency.
314 This changes secondary expansion so that ONLY WHEN we know we have
315 a possibility of needing secondary expansion, do we defer the
316 secondary expansion. This means more parsing the deps but we use
317 a lot less memory (due to the strcache). Also, this fixes
318 Savannah bug #18622.
320 * read.c (eval): Don't parse the dep string here anymore.
321 (record_files): Take the dep argument as an unparsed string. If
322 secondary expansion is enabled AND the prereq string has a '$' in
323 it, then set NEED_2ND_EXPANSION and keep the entire string.
324 Otherwise, parse the dep string here to construct the dep list
325 with the names in the strcache.
327 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
328 duplicate the name string (others are in the strcache).
330 * implicit.c: Remove struct idep and free_idep_chain(): unused.
331 (struct patdeps): New structure to store prereq information.
332 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
333 which prerequisites need expansion, and expand only those.
335 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
336 and enter_prereqs(). split_prereqs() takes a fully-expanded string
337 and splits it into a DEP list, handling order-only prereqs.
338 (enter_prereqs): This function enters a list of DEPs into the file
339 database. If there's a stem defined, expand any pattern chars.
340 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
341 set. Use the above functions.
342 (snap_deps): Only perform second expansion on prereqs that need it,
343 as defined by the NEED_2ND_EXPANSION flag.
344 (print_prereqs): New function to print the prereqs
345 (print_file): Call print_prereqs() rather than print inline.
347 * hash.h (STRING_COMPARE): Take advantage of strcache() by
348 comparing pointers.
349 (STRING_N_COMPARE): Ditto.
350 (ISTRING_COMPARE): Ditto.
352 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
353 (parse_file_seq): Return void*
354 * read.c (parse_file_seq): Return void*.
355 (eval): Invoke macroized version of parse_file_seq()
356 * default.c (set_default_suffixes): Ditto.
357 * file.c (split_prereqs): Ditto.
358 * function.c (string_glob): Ditto.
359 * main.c (main): Ditto.
360 * rule.c (install_pattern_rule): Ditto.
362 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
364 2009-09-16 Paul Smith <psmith@gnu.org>
366 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
367 convert to macros.
368 * dep.h: Create alloc_dep() / free_dep() macros.
370 * implicit.c (pattern_search): Take advantage of the new
371 parse_file_seq() to add the directory prefix to each prereq.
373 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
374 all. Avoid reversing chains. Support adding prefixes.
375 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
376 cached/non-cached results.
377 (eval): Remove multi_glob() & invoke new parse_file_seq().
378 * rule.c (install_pattern_rule): Ditto.
379 * main.c (main): Ditto.
380 * implicit.c (pattern_search): Ditto.
381 * function.c (string_glob): Ditto.
382 * file.c (parse_prereqs): Ditto.
383 * default.c (set_default_suffixes): Ditto.
385 * variable.c (parse_variable_definition): Don't run off the end of
386 the string if it ends in whitespace (found with valgrind).
388 * commands.c (set_file_variables): Keep space for all targets in
389 $? if -B is given (found with valgrind).
391 2009-09-15 Paul Smith <psmith@gnu.org>
393 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
394 (xcalloc): Add new function.
395 * make.h: New declarations.
397 * ar.c (ar_glob_match): New calling method for concat().
398 * main.c (main): Ditto.
399 (decode_env_switches): Ditto.
400 * read.c (eval_makefile): Ditto.
401 (tilde_expand): Ditto.
402 (parse_file_seq): Ditto.
403 * variable.c (target_environment): Ditto.
404 (sync_Path_environment): Ditto.
406 * ar.c (ar_glob_match): Use xcalloc().
407 * dir.c (file_impossible): Ditto.
408 * file.c (enter_file): Ditto.
409 * job.c (new_job): Ditto.
410 * read.c (parse_file_seq): Ditto.
411 * vmsfunctions.c (opendir): Ditto.
413 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
415 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
416 inside the loop that looks up environment for PATH.
418 2009-08-31 Eli Zaretskii <eliz@gnu.org>
420 * function.c (windows32_openpipe): Update envp after calling
421 sync_Path_environment.
423 2009-08-02 Paul Smith <psmith@gnu.org>
425 * remake.c (notice_finished_file): Ensure file->cmds is not null
426 before looping through them. Fixes Savannah bug #21824.
428 * doc/make.texi (Wildcard Examples): Clarify when objects is
429 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
430 (Include): Clarify the behavior of -include.
431 Fixes Savannah bug #18963.
433 2009-08-01 Paul Smith <psmith@gnu.org>
435 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
436 etc. come on the command line. Fixes Savannah bug #27093.
438 * expand.c (expand_argument): If the argument is large enough use
439 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
441 * variable.c (do_variable_definition): Avoid using alloca() to
442 hold values, which can be large. Fixes Savannah bug #23960.
444 * job.c (new_job): Use memmove() instead of strcpy() since both
445 pointers are in the same memory block. Fixes Savannah bug #27148.
446 Patch by Petr Machata.
448 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
450 * job.c (construct_command_argv_internal): Add "ulimit" and
451 "unset" to the sh_cmds for Unixy shells.
453 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
455 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
456 that set make_cv_sys_gnu_glob, so they are also correctly set
457 when the cache has been populated before.
459 2009-07-04 Eli Zaretskii <eliz@gnu.org>
461 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
462 exist, as realpath(3) does where it's supported.
464 2006-07-04 Eli Zaretskii <eliz@gnu.org>
466 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
467 (abspath): Support systems that define HAVE_DOS_PATHS (have
468 drive letters in their file names). Use IS_PATHSEP instead of a
469 literal '/' comparison. Fixes Savannah bug #26886.
471 2009-06-14 Paul Smith <psmith@gnu.org>
473 * remake.c (update_file_1): Remember the original file we marked
474 as updating, so we can clear that flag again. If we find a target
475 via vpath, FILE might change.
476 (check_dep): Ditto. Fixes Savannah bug #13529.
477 Patch by Reid Madsen <reid.madsen@tek.com>.
479 2009-06-13 Paul Smith <psmith@gnu.org>
481 * doc/make.texi (MAKEFILES Variable): Be explicit that files
482 included by MAKEFILES cannot give default goals.
483 * read.c (eval): If set_default is not set, pass the no-default-goal
484 value when we read included makefiles. Fixes Savannah bug #13401.
486 * ar.c (ar_name): Ensure that targets with empty parens aren't
487 considered archive member references: archive members must have a
488 non-empty "member" string. Fixes Savannah bug #18435.
490 * function.c (string_glob): Rely on multi_glob() to determine
491 whether files exist or not. Remove call to file_exists_p() which
492 is not always correct. Fixes Savannah bug #21231.
493 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
494 then only files that really exist will be returned.
495 * dep.h: Add new argument to multi_glob().
496 * rule.c (install_pattern_rule): Ditto.
497 * read.c (eval): Ditto.
498 * main.c (main): Ditto.
499 * implicit.c (pattern_search): Ditto.
500 * file.c (parse_prereqs): Ditto.
501 * default.c (set_default_suffixes): Ditto.
503 2009-06-09 Paul Smith <psmith@gnu.org>
505 * commands.c (set_file_variables): If always_make_flag is set,
506 always add the prereq to $?. Fixes Savannah bug #17825.
508 * remake.c (update_file_1): When rebuilding deps of FILE, also try
509 to rebuild the deps of all the also_make targets for that file.
510 Fixes Savannah bug #19108.
512 * implicit.c (pattern_search): Undo test for is_target, added by
513 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
514 Rule Search Algorithm". Fixes Savannah bug #17752.
516 * main.c (clean_jobserver): Clear the jobserver_fds options and
517 set job_slots to the default when we clean up.
518 (define_makeflags): Return the new MAKEFLAGS value.
519 (main): Reset MAKEFLAGS in the environment when we re-exec.
520 Fixes Savannah bug #18124.
522 2009-06-08 Paul Smith <psmith@gnu.org>
524 * read.c (eval): Collapse continuations post-semicolon on target-
525 specific variables. Fixes Savannah bug #17521.
527 2009-06-07 Paul Smith <psmith@gnu.org>
529 * job.c (reap_children): For older systems without waitpid() (are
530 there any of these left?) run wait(2) inside EINTRLOOP to handle
531 EINTR errors. Fixes Savannah bug #16401.
533 * (various): Debug message cleanup. Fixes Savannah bug #16469.
535 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
537 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
538 not the end, to catch second expansion $(eval ...) defining new
539 target/prereq relationships during snap_deps.
540 Fixes Savannah bug #24622.
542 * read.c (record_files): The second-expansion "f->updating" hack
543 was not completely correct: if assumed that the target with
544 commands always had prerequisites; if one didn't then the ordering
545 was messed up. Fixed for now to use f->updating to decide whether
546 to preserve the last element in the deps list... but this whole
547 area of constructing and reversing the deps list is too confusing
548 and needs to be reworked. Fixes Savannah bug #21198.
550 2009-06-06 Paul Smith <psmith@gnu.org>
552 * hash.c (hash_insert): Remove useless test for NULL.
553 Fixes Savannah bug #21823.
555 * make.h: Move SET_STACK_SIZE determination to make.h.
556 * main.c (main): New global variable, STACK_LIMIT, holds the
557 original stack limit when make was started.
558 * job.c (start_job_command): Reset the stack limit, if we changed it.
559 Fixes Savannah bug #22010.
561 * remake.c (check_dep): Only set the target's state to not-started
562 if it's not already running. Found this while testing -j10 builds
563 of glibc: various targets were being rebuilt multiple times.
564 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
565 bug #15919.
567 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
568 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
569 Bugzilla bug 10246.
571 2009-06-04 Paul Smith <psmith@gnu.org>
573 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
575 * maintMakefile: Modify access of config and gnulib Savannah
576 modules to use GIT instead of CVS.
578 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
579 Fixes Savannah bug #24655.
581 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
582 this can happen during some invocations of $(eval ...) for example.
583 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
585 2009-06-02 Paul Smith <psmith@gnu.org>
587 * configure.in: Check for fileno()
588 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
589 for the makefile file so invocations of $(shell ...) don't inherit it.
590 Fixes Savannah bug #24277.
592 2009-06-01 Paul Smith <psmith@gnu.org>
594 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
595 expansion was handled incorrectly. Rework the default goal
596 handling to save the variable only. Remove default_goal_file and
597 default_goal_name.
598 * read.c (eval): Check default_goal_var, not default_goal_name.
599 * read.c (record_target_var): Don't check default_goal_file here.
601 2009-05-31 Paul Smith <psmith@gnu.org>
603 * main.c (main): Expand the .DEFAULT_GOAL variable before using
604 it, and if the multi_glob() returns nothing (say it expanded to
605 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
607 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
608 $(and ..) to the reference. Fixes Savannah bug #25694.
610 * make.1: Be clear that some recipes will be executed even with -n.
611 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
613 * doc/make.texi (Override Directive): Make more clear how
614 overrides and appends interact.
615 Elucidates part of Savannah bug #26207.
617 * read.c (record_target_var): Don't reset the origin on
618 target-specific variables; try_variable_definition() will handle
619 this correctly. Fixes Savannah bug #26207.
621 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
622 Fixes Savannah bug #25712.
624 * implicit.c (pattern_search): Keep a pointer to the beginning of
625 the filename and save that instead of the constructed pointer.
626 Fixes Savannah bug #26593.
627 Patch by Mark Seaborn <mrs@mythic-beasts.com>
629 2009-05-30 Paul Smith <psmith@gnu.org>
631 * doc/make.texi (Multi-Line): Add a description of the new abilities
632 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
633 "command sequence" vs. "recipe" syntax.
634 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
635 after a define, to create variables with those flavors.
637 2009-05-25 Paul Smith <psmith@gnu.org>
639 Reworked the parser for variable assignments to allow multiple
640 modifiers, and in any order. Also allows variable and
641 prerequisites to be modifier names ('export', 'private', etc.)
643 * NEWS: Add notes about user-visible changes.
645 * read.c (struct vmodifiers): Remember what modifiers were seen.
646 (parse_var_assignment): New function to parse variable assignments.
647 (eval): Call the new function. Handle variable assignments earlier.
649 * variable.c (parse_variable_definition): Only parse; don't create var.
650 (assign_variable_definition): Call parse, then create the var.
652 2009-05-24 Paul Smith <psmith@gnu.org>
654 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
655 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
657 2009-03-14 Eli Zaretskii <eliz@gnu.org>
659 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
660 Fixes Savannah bug #25412.
662 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
663 prototype for xmalloc.
664 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
665 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
666 Loop over an array of extensions, instead of duplicating the same
667 code inline. Use SearchPath followed by CreateFile, instead of
668 the obsolete OpenFile. Fixes Savannah bug #17277.
669 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
670 to `find_file'. Fixes Savannah bug #25662.
672 2009-03-07 Eli Zaretskii <eliz@gnu.org>
674 * function.c (func_shell): Don't close pipedes[1] if it is -1.
675 Fixes Savannah bug #20495.
677 2009-02-28 Ralf Wildenhues <address@hidden>
679 * doc/make.texi (Instead of Execution): Document interaction of
680 -t with phony targets.
682 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
684 Introduce a new keyword "private" which applies to target-specific
685 variables and prevents their values from being inherited.
687 * variable.h (struct variable): Add private_var flag to each variable.
688 Add a flag to specify which list entry switches to the parent target.
689 * variable.c (define_variable_in_set): Initialize private_var flag.
690 (lookup_variable): Skip private variables in parent contexts.

697 2008-10-26 Paul Smith <psmith@gnu.org>
699 * configure.in: Check for strndup().
700 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
701 if it's available.
702 * make.h: Rename savestring to xstrndup.
703 * commands.c (chop_commands): Ditto.
704 * function.c (func_foreach): Ditto.

708 2008-09-30 Eli Zaretskii <eliz@gnu.org>
710 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
711 "-gstabs+ -ggdb3".
713 * w32/subproc/build.bat (GCCBuild): Likewise.
715 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
717 * job.c (construct_command_argv_internal): Avoid extra backslash
718 in batch-mode Unixy shells. Under DB_JOBS, display the contents
719 of the batch file.
721 2008-05-31 Eli Zaretskii <eliz@gnu.org>
723 * README.W32.template: Remove obsolete text about non-support for
724 -jN without Unixy shell. Remove obsolete text about not supplying
725 Visual Studio project files (we do supply them). Modify text to
726 prefer GCC builds to MSC builds.
728 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
730 * doc/make.texi (Empty Targets): Fix typo.
732 2008-03-27 Paul Smith <psmith@gnu.org>
734 Fix Savannah bug #22379:
735 * ar.c (ar_glob_match): Zero the allocated structure.
736 * read.c (parse_file_seq): Ditto.
738 2008-03-08 Brian Dessent <brian@dessent.net>
740 * maintMakefile: Update Translation Project location.
742 2008-01-26 Eli Zaretskii <eliz@gnu.org>
744 * variable.c (target_environment): Don't use shell_var if its
745 `value' field is NULL.
747 2007-12-22 Eli Zaretskii <eliz@gnu.org>
749 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
751 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
752 (TEXINFOS): Value changed to `doc/make.texi'.
753 (.SUFFIXES): Use .texi instead of .texinfo.
754 (make.info, make.dvi): Depend on doc/make.texi.
755 (.texi.info): New target, instead of ".texinfo.info". Change -I
756 switch to $(MAKEINFO) to look in doc/. Use --no-split.
757 (.texi): New target, instead of ".texinfo". Change -I switch to
758 $(MAKEINFO) to look in doc/. Use --no-split.
759 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
760 switch to $(MAKEINFO) to look in doc/.
761 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
762 "*.i[0-9][0-9]" (due to --no-split above).
763 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
764 (html, make_1.html): New targets.
765 (.PHONY): Add "html".
766 (.SUFFIXES): Add .html.
768 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
770 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
771 HAVE_DECL_SYS_SIGLIST.
773 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
774 build does not use child_execute_job.
776 * variable.c (define_automatic_variables) [__MSDOS__]: Always
777 export the SHELL environment variable to the child.
779 2007-12-22 Eli Zaretskii <eliz@gnu.org>
781 * config.h.W32: Include sys/types.h.
782 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
784 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
785 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
786 also `:'.
788 2007-11-04 Paul Smith <psmith@gnu.org>
790 * doc/make.texi: Convert references to "commands", "command
791 lines", and "command script" to "recipe".
792 * NEWS: Ditto.
793 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
794 Ditto.
796 2007-10-27 Bruno Haible <bruno@clisp.org>
798 * remake.c (f_mtime): Print time difference values between 100 and
799 ULONG_MAX in fixed-point notation rather than in exponention notation.
801 2007-10-12 Eli Zaretskii <eliz@gnu.org>
803 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
804 a more complex value than a simple shell: if it's not a default
805 shell now then expand it and see if is a default shell then.
807 2007-10-10 Eli Zaretskii <eliz@gnu.org>
809 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
810 pathnames, with const strings.
811 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
812 from the template (used for building from CVS, not a dist).
814 2007-10-10 Paul Smith <psmith@gnu.org>
816 * make.h: Add a prototype for w32_kill() (change suggested by
817 Yongwei Wu <wuyongwei@gmail.com>).
819 2007-09-21 Eli Zaretskii <eliz@gnu.org>
821 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
822 directories in Path.
824 2007-09-12 Paul Smith <psmith@gnu.org>
826 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
827 Provided by Diego Biurrun <diego@biurrun.de>
828 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
829 Provided by Diego Biurrun <diego@biurrun.de>
831 2007-09-11 Paul Smith <psmith@gnu.org>
833 * doc/make.texi (Special Variables): Moved this into the "How to
834 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
835 (MAKEFILE_LIST) No longer a section; this was added into the
836 "Special Variables" section.
837 (Rule Introduction): Reference .RECIPEPREFIX.
838 (Simple Makefile): Ditto.
839 (Rule Syntax): Ditto.
840 (Command Syntax): Ditto.
841 (Error Messages): Ditto.
843 2007-09-10 Paul Smith <psmith@gnu.org>
845 * commands.c (print_commands): Don't print an extra line in the
846 command scripts. Prefix the command scripts with cmd_prefix, not \t.
848 * read.c (construct_include_path): Add the full string to the cache; we
849 were chopping the last char.
851 * NEWS: Announce the .RECIPEPREFIX special variable.
852 * variable.c (lookup_special_var): Rename from handle_special_var().
853 (lookup_variable): Call the new name.
854 (set_special_var): New function: handle setting of special variables.
855 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
856 (do_variable_definition): Call it.
857 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
858 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
859 * main.c (main): Create the .RECIPEPREFIX special variable.
860 * read.c (eval): Remove the cmd_prefix characters from the command
861 scripts here, so they're not stored in the commands array at all,
862 rather than waiting and stripping them out during command construction.
863 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
865 2007-08-15 Paul Smith <psmith@gnu.org>
867 * doc/make.texi (GNU Free Documentation License): The fdl.texi
868 file has had the section info removed, so add some to make.texi
869 before we include it.
871 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
873 * remake.c (check_dep): Reset the target state for intermediate
874 files. They might have been considered before but not updated
875 then (order-only for example) but they will be this time.
876 Fixes Savannah bug #'s 3330 and 15919.
878 2007-07-21 Eli Zaretskii <eliz@gnu.org>
880 Fix Savannah bug #20549:
881 * function.c (func_shell): Call construct_command_argv with zero
882 value of FLAGS.
883 * job.c (construct_command_argv_internal): New argument FLAGS; all
884 callers changed.
885 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
886 just_print_flag.
887 * job.h (construct_command_argv_internal): Update prototype.
889 2007-07-13 Paul Smith <psmith@gnu.org>
891 * file.c (expand_deps): Use variable_buffer as the start of the
892 buffer, not the original pointer (in case it was reallocated).
893 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
894 Fixes Savannah bug #20452.
896 2007-07-04 Paul Smith <psmith@gnu.org>
898 * (ALL FILES): Update to GPLv3.
899 * (ALL FILES): Update copyright for 2007.

903 2007-06-29 Thiemo Seufer <ths@mips.com>
905 * maintMakefile: Update Translation Project location.
907 2007-06-13 Paul Smith <psmith@gnu.org>
909 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
910 "Expansion of a deferred"
911 Fixes Savannah bug #20018.
913 * expand.c (variable_expand_for_file): Preserve the value of

915 Fixes Savannah bug #20033.
917 2007-05-11 Paul Smith <psmith@gnu.org>
919 * job.c (new_job): Add debug info to specify where make found the
920 command script it is running to build a target.
921 Fixes Savannah bug #18617.
923 * default.c (default_suffixes,default_suffix_rules,default_variables):
924 Add support for Objective C. Fixes Savannah bug #16389.
925 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
927 * function.c (func_lastword): Initialize p.
929 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
930 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
931 Dave Korn <dave.korn@artimi.com>
933 2007-05-08 Paul Smith <psmith@gnu.org>
935 Fix Savannah bug #19656:
937 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
939 * make.h: Change all case-insensitive string compares to use
940 strcasecmp() (from POSIX). If we don't have that but do have one
941 of the others, define strcasecmp to be one of those instead. If
942 we don't have any, declare a prototype for our own version.
944 * misc.c (strcasecmp): Use this if we can't find any native
945 case-insensitive string comparison function.
946 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
947 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
948 strcmpi().
949 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
950 strcasecmp() instead of stricmp().
951 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
952 instead of strcmpi().
953 * acinclude.m4: Remove the strcasecmp() check from here.
955 2007-03-21 Paul Smith <psmith@gnu.org>
957 * configure.in: Don't turn on case-insensitive file system support
958 if --disable-... is given. Fixes Savannah bug #19348.
960 2007-03-19 Paul Smith <psmith@gnu.org>
962 * ALL: Use the strcache for all file name strings, or other
963 strings which we will never free. The goal is to save memory by
964 avoiding duplicate copies of strings. However, at the moment this
965 doesn't save much memory in most situations: due to secondary
966 expansion we actually save prerequisite lists twice (once before
967 the secondary expansion, and then again after it's been parsed
968 into individual file names in the dep list). We will resolve this
969 in a future change, by doing the parsing up-front for targets
970 where secondary expansion is not set.
972 Moving things into the strcache also allows us to use const
973 pointers in many more places.
975 2007-01-03 Paul Smith <psmith@gnu.org>
977 * make.h (ENULLLOOP): Reset errno after each failed invocation of
978 the function, not just the first. Fixes Savannah bug #18680.
980 2006-11-18 Paul Smith <psmith@gnu.org>
982 * strcache.c (strcache_add_len): Don't allocate a new buffer
983 unless the string is not already nil-terminated. Technically this
984 is a violation of the standard, since we may be passed an array
985 that is not long enough to test one past. However, in make this
986 is never true since we only use nil-terminated strings or
987 sub-strings thereof.
989 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
991 * main.c: New global cmd_prefix, defaults to '\t'.
992 * job.c (construct_command_argv_internal): Use cmd_prefix instead
993 of '\t'.
995 * dir.c: Constified.
996 (dir_contents_file_exists_p): Check for an error return from
997 readdir(), just in case.
999 * commands.c: Constified.
1000 * default.c: Constified.
1001 * expand.c: Constified.
1002 * function.c: Partial constification.
1003 * variable.c: Partial constification.
1004 * vmsify.c: Constification. Hard to test this but I hope I didn't
1005 screw it up!
1006 * vpath.c: Partial constification.
1007 * w32/pathstuff.c: Partial constification.
1009 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1011 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1012 backslashes and drive letters as absolute.
1014 2006-10-22 Paul Smith <psmith@gnu.org>
1016 * main.c (struct command_switch): Use const and void*.
1018 2006-10-21 Paul Smith <psmith@gnu.org>
1020 * ar.c: Constified.
1021 * arscan.c: Constified.
1023 2006-09-30 Paul Smith <psmith@gnu.org>
1025 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1026 point to lastword since the example was updated.
1027 Fixes Savannah bug #16304.
1028 (Secondary Expansion): Correct example description.
1029 Fixes Savannah bug #16468.
1030 (Makefile Contents): Clarify that comments cannot appear within
1031 variable references or function calls.
1032 Fixes Savannah bug #16577.
1033 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1034 Fixes Savannah bug #17701.
1035 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1036 (Prerequisite Types): Added an example of using order-only
1037 prerequisites. Fixes Savannah bug #17880.
1038 (Rule Syntax): "lise" -> "list"
1039 (Multiple Rules): ... -> @dots{}
1040 (Splitting Lines): ditto.
1042 * remake.c (update_file_1): Prereqs that don't exist should be
1043 considered changed, for the purposes of $?.
1044 Fixes Savannah bug #16051.
1046 * make.1: Remove extraneous "+".
1047 Fixes Savannah bug #16652.
1049 2006-09-06 Paul D. Smith <psmith@gnu.org>
1051 * configure.in: Include sys/types.h when checking for sys/wait.h.
1053 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1055 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1056 $PATH_SEPARATOR.
1058 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1059 Normally, it is defined in config.h.
1061 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1062 well.
1064 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1065 sh_chars_sh for Windows platforms that emulate Unix.

1083 2006-04-20 Paul D. Smith <psmith@gnu.org>
1085 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1086 that don't have extended grep.
1087 (cvsclean): Use $(PERL) instead of perl.
1089 2006-04-09 Paul D. Smith <psmith@gnu.org>
1091 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1093 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1094 inner-scope variables don't mask outer-scope variables.
1096 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1097 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1098 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1099 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1100 values from memory allocation functions: they return void* and so
1101 don't need to be cast. Also remove (char *) casts of arguments to
1102 xrealloc().
1104 * configure.in: Remove checks for memcpy/memmove/strchr.
1106 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1108 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp
1109 calls to memset/memcpy/memmove/memcmp calls.

1116 2006-04-06 Paul D. Smith <psmith@gnu.org>
1118 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1119 require an ISO C 1989 standard compiler and runtime library.
1121 * Makefile.am: Remove the ansi2knr feature.
1123 * make.h: Remove the PARAMS() macro definition and all uses of it.
1125 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
1126 * commands.c, commands.h, config.h-vms.template: Ditto.

1129 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
1131 * NEWS: Update.
1133 2006-04-01 Paul D. Smith <psmith@gnu.org>
1135 Version 3.81 released.
1137 * NEWS: Updated for 3.81.
1139 * README.cvs: Mention that vpath builds are not supported out of
1140 CVS. Fixes Savannah bug #16236.
1141 Remove update of make.texi from the list of things to do; we use
1142 version.texi now.
1144 2006-03-26 Paul D. Smith <psmith@gnu.org>
1146 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1147 support from automake, as described in the Texinfo manual.
1149 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1151 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1152 with lastslash, since the latter points to filename, not to
1153 target.
1154 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1155 Declare and define sh_chars_sh[].
1157 2006-03-23 Paul D. Smith <psmith@gnu.org>
1159 * configure.in: Look for build.sh.in in $srcdir so it will be
1160 built for remote configurations as well.
1162 * Makefile.am: Make sure to clean up build.sh during distclean.
1163 Fixes Savannah bug #16166.
1165 * misc.c (log_access): Takes a const char *.
1166 * function.c (fold_newlines): Takes an unsigned int *.
1167 Both fixes for Savannah bug #16170.
1169 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1171 * implicit.c (pattern_search): Call set_file_variables only
1172 if we have prerequisites that need second expansion. Fixes
1173 Savannah bug #16140.
1175 2006-03-19 Paul D. Smith <psmith@gnu.org>
1177 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1178 memory on hosts that don't support it directly.
1180 * README.cvs: Add information on steps for making a release (to
1181 make sure I don't forget any).
1183 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1184 function.
1185 (die): Cleanup code was removed from here; call the new function.
1186 (main): If we are re-execing, clean up the jobserver first so we
1187 don't leak file descriptors.
1188 Reported by Craig Fithian <craig.fithian@citigroup.com>
1190 2006-03-17 Paul D. Smith <psmith@gnu.org>
1192 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1193 allow multiple concurrent runs.
1194 Patch from Joseph Myers <joseph@codesourcery.com>
1196 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1198 * dep.h (struct dep): Add the stem field.
1199 * misc.c (alloc_dep, free_dep): New functions.
1200 (copy_dep_chain): Copy stem.
1201 (free_dep_chain): Use free_dep.
1202 * read.c (record_files): Store stem in the dependency line.
1203 * file.c (expand_deps): Use stem stored in the dependency line. Use
1204 free_dep_chain instead of free_ns_chain.
1205 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1206 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1207 * main.c (main, handle_non_switch_argument): Ditto.
1208 * remake.c (check_dep): Ditto.
1209 * rule.c (convert_suffix_rule, freerule): Ditto.
1211 2006-03-14 Paul D. Smith <psmith@gnu.org>
1213 * expand.c (variable_append): Instead of appending everything then
1214 expanding the result, we expand (or not, if it's simple) each part
1215 as we add it.
1216 (allocated_variable_append): Don't expand the final result.
1217 Fixes Savannah bug #15913.
1219 2006-03-09 Paul Smith <psmith@gnu.org>
1221 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1222 listed non-existent files as changed. Turns out there's a bug in
1223 the Linux kernel builds which means that this change causes
1224 everything to rebuild every time. We will re-introduce this fix
1225 in the next release, to give them time to fix their build system.
1226 Fixes Savannah bug #16002.
1227 Introduces Savannah bug #16051.
1229 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1230 we *don't* find UNIX "/".
1231 Reported by David Ergo <david.ergo@alterface.com>
1233 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1235 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1236 locator function find_and_set_default_shell if SHELL came from the
1237 command line.
1239 2006-02-20 Paul D. Smith <psmith@gnu.org>
1241 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1242 to be null; don't core in that case.
1244 2006-02-19 Paul D. Smith <psmith@gnu.org>
1246 * commands.c (set_file_variables): Realloc, not malloc, the static
1247 string values to avoid memory leaks.
1249 * expand.c (recursively_expand_for_file): Only set reading_file to
1250 an initialized value.
1252 * implicit.c (pattern_search): We need to make a copy of the stem
1253 if we get it from an intermediate dep, since those get freed.
1255 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1256 begin with ".".
1257 (enter_file) [VMS]: Ditto.
1258 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1260 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1262 * job.c (construct_command_argv_internal): Fix last change.
1264 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1265 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1266 the calls to _beginthreadex.
1268 * expand.c (recursively_expand_for_file): Initialize `save' to
1269 prevent compiler warnings.
1271 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1273 * job.c (construct_command_argv_internal): Don't create a temporary
1274 script/batch file if we are under -n. Call _setmode to switch the
1275 script file stream to text mode.
1277 2006-02-17 Paul D. Smith <psmith@gnu.org>
1279 * variable.c (merge_variable_set_lists): Don't try to merge the
1280 global_setlist. Not only is this useless, but it can lead to
1281 circularities in the linked list, if global_setlist->next in one
1282 list gets set to point to another list which also ends in
1283 global_setlist.
1284 Fixes Savannah bug #15757.
1286 2006-02-15 Paul D. Smith <psmith@gnu.org>
1288 Fix for Savannah bug #106.
1290 * expand.c (expanding_var): Keep track of which variable we're
1291 expanding. If no variable is being expanded, it's the same as
1292 reading_file.
1293 * make.h (expanding_var): Declare it.
1294 * expand.c (recursively_expand_for_file): Set expanding_var to the
1295 current variable we're expanding, unless there's no file info in
1296 it (could happen if it comes from the command line or a default
1297 variable). Restore it before we exit.
1298 * expand.c (variable_expand_string): Use the expanding_var file
1299 info instead of the reading_file info.
1300 * function.c (check_numeric): Ditto.
1301 (func_word): Ditto.
1302 (func_wordlist): Ditto.
1303 (func_error): Ditto.
1304 (expand_builtin_function): Ditto.
1305 (handle_function): Ditto.
1307 2006-02-14 Paul D. Smith <psmith@gnu.org>
1309 * read.c (eval): Even if the included filenames expands to the
1310 empty string we still need to free the allocated buffer.
1312 * implicit.c (pattern_search): If we allocated a variable set for
1313 an impossible file, free it.
1314 * variable.c (free_variable_set): New function.
1315 * variable.h: Declare it.
1317 * read.c (read_all_makefiles): Makefile names are kept in the
1318 strcache, so there's never any need to alloc/free them.
1319 (eval): Ditto.
1321 * main.c (main): Add "archives" to the .FEATURES variable if
1322 archive support is enabled.
1323 * doc/make.texi (Special Variables): Document it.
1325 2006-02-13 Paul D. Smith <psmith@gnu.org>
1327 * implicit.c (pattern_search): Add checking for DOS pathnames to
1328 the pattern rule target LASTSLASH manipulation.
1329 Fixes Savannah bug #11183.
1331 2006-02-11 Paul D. Smith <psmith@gnu.org>
1333 * (ALL FILES): Updated copyright and license notices.
1335 2006-02-10 Paul D. Smith <psmith@gnu.org>
1337 A new internal capability: the string cache is a read-only cache
1338 of strings, with a hash table interface for fast lookup. Nothing
1339 in the cache will ever be freed, so there's no need for reference
1340 counting, etc. This is the beginning of a full solution for
1341 Savannah bug #15182, but for now we only store makefile names here.
1343 * strcache.c: New file. Implement a read-only string cache.
1344 * make.h: Add prototypes for new functions.
1345 * main.c (initialize_global_hash_tables): Initialize the string cache.
1346 (print_data_base): Print string cache stats.
1347 * read.c (eval_makefile): Use the string cache to store makefile
1348 names. Rewrite the string allocation to be sure we free everything.
1350 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1352 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1353 directory time stamp didn't change, except on FAT filesystems.
1354 Suggested by J. David Bryan <jdbryan@acm.org>.
1356 2006-02-09 Paul D. Smith <psmith@gnu.org>
1358 * function.c (func_or): Implement a short-circuiting OR function.
1359 (func_and): Implement a short-circuiting AND function.
1360 (function_table_init): Update the table with the new functions.
1361 * doc/make.texi (Conditional Functions): Changed the "if" section
1362 to one on general conditional functions. Added documentation for
1363 $(and ...) and $(or ...) functions.
1364 * NEWS: Note new $(and ...) and $(or ...) functions.
1366 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1368 * job.h (struct child): Add the dontcare bitfield.
1369 * job.c (new_job): Cache dontcare flag.
1370 * job.c (reap_children): Use cached dontcare flag instead of the
1371 one in struct file. Fixes Savannah bug #15641.
1373 2006-02-06 Paul D. Smith <psmith@gnu.org>
1375 * vpath.c (selective_vpath_search): If the file we find has a
1376 timestamp from -o or -W, use that instead of the real time.
1377 * remake.c (f_mtime): If the mtime is a special token from -o or
1378 -W, don't overwrite it with the real mtime.
1379 Fixes Savannah bug #15341.
1381 Updates from Markus Mauhart <qwe123@chello.at>:
1383 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1384 (process_signal, process_last_err, process_exit_code): Manage
1385 invalid handle values.
1386 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1387 manage invalid handles; remove them.
1388 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1389 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1390 * README.cvs: Updates for building from CVS.
1392 2006-02-05 Paul D. Smith <psmith@gnu.org>
1394 * file.c (enter_file): Keep track of the last double_colon entry,
1395 to avoid walking the list every time we want to add a new one.
1396 Fixes Savannah bug #15533.
1397 * filedef.h (struct file): Add a new LAST pointer.
1399 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1400 the comparison. For 64-bits systems the result of the subtraction
1401 might not fit into an int. Use comparison instead.
1402 Fixes Savannah bug #15534.
1404 * doc/make.texi: Update the chapter on writing commands to reflect
1405 the changes made in 3.81 for backslash/newline and SHELL handling.
1407 2006-02-01 Paul D. Smith <psmith@gnu.org>
1409 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1410 variable st is not used when it's not initialized.
1411 Patch from Eli Zaretskii <eliz@gnu.org>.
1413 2006-01-31 Paul D. Smith <psmith@gnu.org>
1415 * README.W32.template: Applied patch #4785 from
1416 Markus Mauhart <qwe123@chello.at>.
1417 * README.cvs: Applied patch #4786 from
1418 Markus Mauhart <qwe123@chello.at>.
1419 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1420 J. Grant <jg@jguk.org>.
1422 * main.c: Update the copyright year in the version output.
1423 * prepare_w32.bat: Remove this file from the distribution.
1425 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1427 * remake.c (update_goal_chain): Set g->changed instead of
1428 incrementing it, as it is only 8-bit wide, and could overflow if
1429 many commands got started in update_file.
1431 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1433 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1434 MAXIMUM_WAIT_OBJECTS.
1435 (process_wait_for_any_private): Change dimension of handles[]
1436 array to MAXIMUM_WAIT_OBJECTS.
1437 (process_used_slots): New function.
1438 (process_register): Don't register more processes than the
1439 available number of slots.
1440 (process_easy): Don't start new processes if all slots are used up.
1442 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1443 are already more children than sub_proc.c can handle, behave as if
1444 the load were too high.
1445 (start_job_command): Fix a typo in error message when process_easy
1446 fails.
1448 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1450 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1451 the shell is not sh.exe.
1453 * job.c (create_batch_file): Renamed from create_batch_filename;
1454 all callers changed. Don't close the temporary file; return its
1455 file descriptor instead. New arg FD allows to return the file
1456 descriptor.
1457 (construct_command_argv_internal): Use _fdopen instead of fopen to
1458 open the batch file.
1460 2006-01-04 Paul D. Smith <psmith@gnu.org>
1462 * readme.vms: Updates for case-insensitive VMS file systems from
1463 Hartmut Becker <Hartmut.Becker@hp.com>.
1464 * dir.c (vms_hash): Ditto.
1465 * vmsify.c (copyto): Ditto.
1466 * vmsfunctions.c (readdir): Ditto.
1468 * make.1: Add a section on the exit codes for make.

1475 doesn't exist.
1477 * read.c (eval): Be sure to strip off trailing whitespace from the
1478 prerequisites list properly. Also, initialize all fields in
1479 struct dep when creating a new one.
1481 2005-12-28 Paul D. Smith <psmith@gnu.org>
1483 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1484 disable warnings for MSC.
1485 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1487 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1489 * doc/make.texi (Execution): Add a footnote about changes in
1490 handling of backslash-newline sequences. Mention the differences
1491 on MS-DOS and MS-Windows.
1493 * NEWS: More details about building the MinGW port and a pointer
1494 to README.W32. Fix the section name that describes the new
1495 backward-incompatible processing of backslash-newline sequences.
1496 The special processing of SHELL set to "cmd" is only relevant to
1497 MS-Windows, not MS-DOS.
1499 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1501 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1502 to DWORD, to avoid compiler warnings.
1503 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1504 use %ld in format, to avoid compiler warnings.
1506 * doc/make.texi (Special Targets): Fix a typo.
1507 (Appending): Fix cross-reference to Setting.
1508 (Special Variables, Secondary Expansion, File Name Functions)
1509 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1510 periods after a sentence.
1511 (Execution): Add @: after "e.g.".
1512 (Environment): Fix punctuation.
1513 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1514 (Shell Function, Target-specific): Add @: after "vs."
1516 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1518 * read.c (record_target_var): Initialize variable's export field
1519 with v_default instead of leaving it "initialized" by whatever
1520 garbage happened to be on the heap.
1522 2005-12-12 Paul D. Smith <psmith@gnu.org>
1524 * make.1: Fix some display errors and document all existing options.
1525 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1527 2005-12-11 Paul D. Smith <psmith@gnu.org>
1529 * implicit.c (pattern_search): If 2nd expansion is not set for
1530 this implicit rule, replace the pattern with the stem directly,
1531 and don't re-expand the variable list. Along with the other
1532 .SECONDEXPANSION changes below, fixes bug #13781.
1534 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1536 * implicit.c (pattern_search): Mark other files that this rule
1537 builds as targets so that they are not treated as intermediates
1538 by the pattern rule search algorithm. Fixes bug #13022.
1540 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1542 * remake.c (notice_finished_file): Propagate the change of
1543 modification time to all the double-colon entries only if
1544 it is the last one to be updated. Fixes bug #14334.
1546 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1548 * function.c (func_flavor): Implement the flavor function which
1549 returns the flavor of a variable.
1550 * doc/make.texi (Functions for Transforming Text): Document it.
1551 * NEWS: Add it to the list of new functions.
1553 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1555 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1556 variable.
1557 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1558 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1560 2005-10-26 Paul Smith <psmith@gnu.org>
1562 * read.c (record_files): Don't set deps flags if there are no deps.
1563 * maintMakefile: We only need to build the templates when we are
1564 creating a distribution, so don't do it for "all".
1566 2005-10-24 Paul D. Smith <psmith@gnu.org>
1568 Make secondary expansion optional: its enabled by declaring the
1569 special target .SECONDEXPANSION.
1571 * NEWS: Update information on second expansion capabilities.
1572 * doc/make.texi (Secondary Expansion): Document the
1573 .SECONDEXPANSION special target and its behavior.
1574 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1575 prerequisite list was found in a static pattern rule.
1576 (free_dep_chain): Declare a prototype.
1577 * file.c (parse_prereqs): New function: break out some complexity
1578 from expand_deps().
1579 (expand_deps): If we aren't doing second expansion, replace % with
1580 the stem for static pattern rules. Call the new function.
1581 * filedef.h (parse_prereqs): Declare a prototype.
1582 * implicit.c (pattern_search): Initialize the new staticpattern
1583 field.
1584 * main.c (second_expansion): Declare a global variable to remember
1585 if the special target has been seen. Initialize the new
1586 staticpattern field for prerequisites.
1587 * make.h: Extern for second_expansion.
1588 * misc.c (free_dep_chain): New function: frees a struct dep list.
1589 * read.c (read_all_makefiles): Initialize the staticpattern field.
1590 (eval_makefile): Ditto.
1591 (record_files): Check for the .SECONDEXPANSION target and set
1592 second_expansion global if it's found.
1593 Use the new free_dep_chain() instead of doing it by hand.
1594 Set the staticpattern field for prereqs of static pattern targets.
1596 2005-10-16 Paul D. Smith <psmith@gnu.org>
1598 * main.c (main): Set CURDIR to be a file variable instead of a
1599 default, so that values of CURDIR inherited from the environment
1600 won't override the make value.
1602 2005-09-26 Paul D. Smith <psmith@gnu.org>
1604 * job.c (construct_command_argv_internal): If the line is empty
1605 remember to free the temporary argv strings.
1606 Fixes bug # 14527.
1608 2005-09-16 Paul D. Smith <psmith@gnu.org>
1610 * job.c (start_job_command): The noerror flag is a boolean (single
1611 bit); set it appropriately.
1612 Reported by Mark Eichin <eichin@metacarta.com>
1614 2005-08-29 Paul D. Smith <psmith@gnu.org>
1616 * function.c (func_error): On Windows, output from $(info ...)
1617 seems to come in the wrong order. Try to force it with fflush().
1619 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1621 * read.c (record_files): Move code that sets stem for static
1622 pattern rules out of the if (!two_colon) condition so it is
1623 also executed for two-colon rules. Fixes Savannah bug #13881.
1625 2005-08-08 Paul D. Smith <psmith@gnu.org>
1627 * make.h: Don't test that __STDC__ is non-0. Some compilers
1628 (Windows for example) set it to 0 to denote "ISO C + extensions".
1629 Fixes bug # 13594.
1631 2005-08-07 Paul D. Smith <psmith@gnu.org>
1633 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1634 conditional (slightly different version of a fix from Eli).
1636 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1637 If make is running in parallel without -k and two jobs die in a
1638 row, but not too close to each other, then make will quit without
1639 waiting for the rest of the jobs to die.
1641 * main.c (die): Don't reset err before calling reap_children() the
1642 second time: we still want it to be in the error condition.
1643 * job.c (reap_children): Use a static variable, rather than err,
1644 to control whether or not the error message should be printed.
1646 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1648 * w32/subproc/sub_proc.c: Include signal.h.
1649 (process_pipe_io, process_file_io): Pass a pointer to a local
1650 DWORD variable to GetExitCodeProcess. If the exit code is
1651 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1653 * job.c [WINDOWS32]: Include windows.h.
1654 (main_thread) [WINDOWS32]: New global variable.
1655 (reap_children) [WINDOWS32]: Get the handle for the main thread
1656 and store it in main_thread.
1658 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1659 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1660 doing anything else. When we are done, close the main thread
1661 handle and exit with status 130.
1663 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1665 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1666 pointer to fprintf.
1668 * main.c (find_and_set_default_shell): If found a DOSish shell,
1669 set sh_found and the value of default_shell, and report the
1670 findings in debug mode.
1672 * job.c (construct_command_argv_internal): Check unixy_shell, not
1673 no_default_sh_exe, to decide whether to use Unixy or DOSish
1674 builtin commands.
1676 * README.W32: Update with info about the MinGW build.
1678 * build_w32.bat: Support MinGW.
1680 * w32/subproc/build.bat: Likewise.
1682 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1683 printing DWORD args.
1685 * function.c (windows32_openpipe): Fix format strings for printing
1686 DWORD args.
1688 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1689 'reap_mode'.
1690 (start_job_command): Fix format string for printing the result of
1691 process_easy.
1692 (start_job_command) [WINDOWS32]: Do not define.
1693 (exec_command): Fix format string for printing HANDLE args.
1695 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1696 to avoid compiler warnings.
1697 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1698 (Note: some of these fixes were submitted independently by J. Grant)
1700 2005-07-30 J. Grant <jg@jguk.org>
1702 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1703 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1704 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1706 2005-07-15 Paul Smith <psmith@gnu.org>
1708 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1709 we don't have a POSIX shell, then revert to the old
1710 backslash-newline behavior (where they are stripped).
1711 Fixes bug #13665.
1713 2005-07-08 Paul D. Smith <psmith@gnu.org>
1715 * config.h.W32.template: Reorder to match the standard config.h,
1716 for easier comparisons.
1717 From J. Grant <jg@jguk.org>
1719 * maintMakefile: Remove .dep_segment before overwriting it, in
1720 case it's not writable or noclobber is set.
1721 * expand.c (variable_expand_string): Cast result of pointer
1722 arithmetic to avoid a warning.
1723 * main.c (switches): Add full-fledged final initializer.
1725 2005-07-06 Paul D. Smith <psmith@gnu.org>
1727 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1728 * signame.c (strsignal): If we found _sys_siglist[] or
1729 __sys_siglist[] use those instead of sys_siglist[].
1730 From Albert Chin <china@thewrittenword.com>
1732 2005-07-04 Paul D. Smith <psmith@gnu.org>
1734 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1735 globfree(); set up to use the GNU versions.
1736 From Martin Zinser <zinser@zinser.no-ip.info>
1738 2005-07-03 Paul D. Smith <psmith@gnu.org>
1740 From J. Grant <jg@jguk.org>:
1742 * README.W32.template: Update the Windows and tested MSVC versions.
1743 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1744 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1745 * build_w32.bat: Ditto.
1746 * w32/subproc/build.bat: Ditto.
1748 2005-06-28 Paul D. Smith <psmith@gnu.org>
1750 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1751 declaration was checked but not present.
1753 2005-06-27 Paul D. Smith <psmith@gnu.org>
1755 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1756 to unsigned long. Fixes Savannah bug #13550.
1758 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1759 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1760 Fixes Savannah bug #13551.
1762 2005-06-26 Paul D. Smith <psmith@gnu.org>
1764 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1765 it if ANSI_STRING is not set.
1767 2005-06-25 Paul D. Smith <psmith@gnu.org>
1769 * read.c (eval): If no filenames are passed to any of the
1770 "include" variants, don't print an error.
1771 * doc/make.texi (Include): Document this.
1772 Fixes Savannah bug #1761.
1774 * job.c (construct_command_argv_internal): Sanitize handling of
1775 backslash/newline pairs according to POSIX: that is, keep the
1776 backslash-newline in the command script, but remove a following
1777 TAB character, if present. In the fast path, make sure that the
1778 behavior matches what the shell would do both inside and outside
1779 of quotes. In the slow path, quote the backslash and put a
1780 literal newline in the string.
1781 Fixes Savannah bug #1332.
1782 * doc/make.texi (Execution): Document the new behavior and give
1783 some examples.
1784 * NEWS: Make a note of the new behavior.
1786 * make.h [WINDOWS32]: #include <direct.h>.
1787 Fixes Savannah bug #13478.
1789 * remake.c (name_mtime): If the stat() of a file fails and the -L
1790 option was given and the file is a symlink, take the best mtime of
1791 the symlink we can get as the mtime of the file and don't fail.
1792 Fixes Savannah bug #13280.
1794 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1795 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1796 inside a variable reference. Make this function static as it's
1797 only used here.
1798 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1799 parsing an unexpanded line looking for semicolons.
1800 Fixes Savannah bug #1454.
1801 * misc.c (remove_comments): Move this to read.c and make it static
1802 as it's only used there. Call find_char_unquote() with new arg.
1803 * make.h: Remove prototypes for find_char_unquote() and
1804 remove_comments() since they're static now.
1806 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1807 its export flag and obtain its value. When we need to re-exec,
1808 increment the value and add it into the environment.
1809 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1810 * NEWS: Mention MAKE_RESTARTS.
1811 * main.c (always_make_set): New variable. Change the -B option to
1812 set this one instead.
1813 (main): When checking makefiles, only set always_make_flag if
1814 always_make_set is set AND the restarts flag is 0. When building
1815 normal targets, set it IFF always_make_set is set.
1816 (main): Avoid infinite recursion with -W, too: only set what-if
1817 files to NEW before we check makefiles if we've never restarted
1818 before. If we have restarted, set what-if files to NEW _after_ we
1819 check makefiles.
1820 Fixes Savannah bug #7566:
1822 2005-06-17 Paul D. Smith <psmith@gnu.org>
1824 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1825 in the prerequisites list.
1827 2005-06-12 Paul D. Smith <psmith@gnu.org>
1829 Fix Savannah bug # 1328.
1831 * configure.in: Check for atexit().
1832 * misc.c (close_stdout): Test stdout to see if writes to it have
1833 failed. If so, be sure to exit with a non-0 error code. Based on
1834 code found in gnulib.
1835 * make.h: Prototype.
1836 * main.c (main): Install close_stdout() with atexit().
1838 2005-06-10 Paul D. Smith <psmith@gnu.org>
1840 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1842 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1843 headers; make vmsWaitForChildren() static; extern vmsify().
1844 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1845 Don't create child_execute_job() here (it's in vmsjobs.c).
1846 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1848 2005-06-09 Paul D. Smith <psmith@gnu.org>
1850 * variable.c (push_new_variable_scope): File variables point
1851 directly to the global_setlist variable. So, inserting a new
1852 scope in front of that has no effect on those variables: they
1853 don't go through current_variable_set_list. If we're pushing a
1854 scope and the current scope is global, push it "the other way" so
1855 that the new setlist is in the global_setlist variable, and
1856 next points to a new setlist with the global variable set.
1857 (pop_variable_scope): Properly undo a push with the new
1858 semantics.
1859 Fixes Savannah bug #11913.
1861 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1863 * job.c (reap_children): Don't die of the command failed but
1864 the dontcare flag is set. Fixes Savannah bug #13216.
1866 * implicit.c (pattern_search): When creating a target from
1867 an implicit rule match, lookup pattern target and set precious
1868 flag in a newly created target. Fixes Savannah bug #13218.
1870 2005-05-13 Paul D. Smith <psmith@gnu.org>
1872 Implement "if... else if... endif" syntax.
1874 * read.c (eval): Push all checks for conditional words ("ifeq",
1875 "else", etc.) down into the conditional_line() function.
1876 (conditional_line): Rework to allow "else if..." clause. New
1877 return value -2 for lines which are not conditionals. The
1878 ignoring flag can now also be 2, which means "already parsed a
1879 true branch". If that value is seen no other branch of this
1880 conditional can be considered true. In the else parsing if there
1881 is extra text after the else, invoke conditional_line()
1882 recursively to see if it's another conditional. If not, it's an
1883 error. If so, raise the conditional value to this level instead
1884 of creating a new conditional nesting level. Special check for
1885 "else" and "endif", which aren't allowed on the "else" line.
1886 * doc/make.texi (Conditional Syntax): Document the new syntax.
1888 2005-05-09 Paul D. Smith <psmith@gnu.org>
1890 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1891 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1892 recurses to the w32 directory, even on non-Windows systems. Use
1893 the method suggested in the automake manual.
1894 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1895 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1897 2005-05-07 Paul D. Smith <psmith@gnu.org>
1899 * main.c (die): If we're dying with a fatal error (not that a
1900 command has failed), write back any leftover tokens before we go.
1902 * job.c (set_child_handler_action_flags): If there are jobs
1903 waiting for the load to go down, set an alarm to go off in 1
1904 second. This allows us to wake up from a potentially long-lasting
1905 read() and start a new job if the load has gone down. Turn it off
1906 after the read.
1907 (job_noop): Dummy signal handler function.
1908 (new_job): Invoke it with the new semantics.
1910 * docs/make.texi: Document secondary expansion. Various cleanups
1911 and random work.
1913 2005-05-03 Paul D. Smith <psmith@gnu.org>
1915 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1916 the targets which are to ultimately be made are called "goals";
1917 see the GNU make manual. Also, MAKECMDGOALS, etc.
1919 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1920 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1921 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1923 2005-05-02 Paul D. Smith <psmith@gnu.org>
1925 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1926 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1927 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1928 functions to vmsjobs.c. #include it into jobs.c.
1930 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1931 jobserver tokens. I found that this happens when an exported
1932 recursive variable contains a $(shell ...) function reference: in
1933 this situation we could "forget" to write back a token.
1935 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1936 we have. It's not reliable to depend on the number of children in
1937 our linked list so keep a separate count.
1938 (new_job): Check jobserver_tokens rather than children &&
1939 waiting_jobs. Increment jobserver_tokens when we get one.
1940 (free_child): If jobserver_tokens is 0, internal error. If it's
1941 >1, write a token back to the jobserver pipe (we don't write a
1942 token for the "free" job). Decrement jobserver_tokens.
1944 * main.c: Add variable master_job_slots.
1945 (main): Set it to hold the number of jobs requested if we're the
1946 master process, when using the jobserver.
1947 (die): Sanity checks: first test jobserver_tokens to make sure
1948 this process isn't holding any tokens we didn't write back.
1949 Second, if master_job_slots is set count the tokens left in the
1950 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1952 2005-04-24 Paul D. Smith <psmith@gnu.org>
1954 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1955 with -l# can lose jobserver tokens, because waiting jobs are not
1956 consulted properly when checking for the "free" token.
1958 * job.c (free_child): Count waiting_jobs as having tokens.
1959 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1960 handle jobs waiting for the load to drop.
1962 2005-04-23 Paul D. Smith <psmith@gnu.org>
1964 * main.c (main): Be careful to not core if a variable setting in
1965 the environment doesn't contain an '='. This is illegal but can
1966 happen in broken setups.
1967 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1969 2005-04-12 Paul D. Smith <psmith@gnu.org>
1971 The second expansion feature causes significant slowdown. Timing
1972 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1973 read the makefile before the feature, to 11+s to do the same
1974 operations after the feature. Additionally, memory usage
1975 increased drastically. To fix this I added some intelligence that
1976 avoids the overhead of the second expansion unless it's required.
1978 * dep.h: Add a new boolean field, need_2nd_expansion.
1980 * read.c (eval): When creating the struct dep for the target,
1981 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1982 (record_files): If there's a "%" in a static pattern rule, it gets
1983 converted to "$*" so set need_2nd_expansion to 1.
1985 * file.c (expand_deps): Rework to be more efficient. Only perform
1986 initialize_file_variables(), set_file_variables(), and
1987 variable_expand_for_file() if the need_2nd_expansion is set.
1989 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1990 (pattern_search): Ditto.
1991 * main.c (handle_non_switch_argument): Ditto.
1992 (main): Ditto.
1993 * read.c (read_all_makefiles): Ditto.
1994 (eval_makefile): Ditto.
1996 2005-04-07 Paul D. Smith <psmith@gnu.org>
1998 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1999 * variable.c (sync_Path_environment): Ditto.
2000 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2002 * main.c (main): Define the .FEATURES variable.
2003 * NEWS: Announce .FEATURES.
2004 * doc/make.texi (Special Variables): Document .FEATURES.
2006 * remake.c (check_dep): If a file is .PHONY, update it even if
2007 it's marked intermediate. Fixes Savannah bug #12331.
2009 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2011 * file.c (expand_deps): Factor out the second expansion and
2012 prerequisite line parsing logic from snap_deps().
2014 * file.c (snap_deps): Use expand_deps(). Expand and parse
2015 prerequisites of the .SUFFIXES special target first. Fixes
2016 Savannah bug #12320.
2018 2005-03-13 Paul D. Smith <psmith@gnu.org>
2020 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2021 Zaretskii.
2023 2005-03-11 Paul D. Smith <psmith@gnu.org>
2025 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2026 available, not undefined (from Earnie Boyd).
2028 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2030 * implicit.c (pattern_search): Mark an intermediate target as
2031 precious if it happened to be a prerequisite of some (other)
2032 target. Fixes Savannah bug #12267.
2034 2005-03-09 Paul D. Smith <psmith@gnu.org>
2036 * read.c (eval_makefile): Add alloca(0).
2037 (eval_buffer): Ditto.
2039 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2041 * main.c (main): Use o_file instead of o_default when defining
2042 the .DEFAULT_TARGET special variable.
2043 * read.c (eval): Use define_variable_global() instead of
2044 define_variable() when setting new value for the .DEFAULT_TARGET
2045 special variable. Fixes Savannah bug #12266.
2047 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2049 * imlicit.c (pattern_search): Mark files for which an implicit
2050 rule has been found as targets. Fixes Savannah bug #12202.
2052 2005-03-04 Paul D. Smith <psmith@gnu.org>
2054 * AUTHORS: Update.
2055 * doc/make.texi (Automatic Variables): Document $|.
2057 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2059 * read.c (record_files): Instead of substituting % with
2060 actual stem value in dependency list replace it with $*.
2061 This fixes stem triple expansion bug.
2063 * implicit.c (pattern_search): Copy stem to a separate
2064 buffer and make it a properly terminated string. Assign
2065 this buffer instead of STEM (which is not terminated) to
2066 f->stem. Instead of substituting % with actual stem value
2067 in dependency list replace it with $*. This fixes stem
2068 triple expansion bug.
2070 2005-03-01 Paul D. Smith <psmith@gnu.org>
2072 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2073 on Windows, as it takes a handle not a pid. Just exit.
2074 Fix from patch #3679, provided by Alessandro Vesely.
2076 * configure.in: Update check for sys_siglist[] from autoconf manual.
2077 * signame.c (strsignal): Update to use the new autoconf macro.
2079 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2081 * read.c (record_files): Add a check for the list of prerequisites
2082 of a static pattern rule being empty. Fixes Savannah bug #12180.
2084 2005-02-28 Paul D. Smith <psmith@gnu.org>
2086 * doc/make.texi (Text Functions): Update docs to allow the end
2087 ordinal for $(wordlist ...) to be 0.
2088 * function.c (func_wordlist): Fail if the start ordinal for
2089 $(wordlist ...) is <1. Matches documentation.
2090 Resolves Savannah support request #103195.
2092 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2093 previously we were stopping when !-q, exactly the opposite. This
2094 has been wrong since version 1.34, in 1994!
2095 (update_file): If we got an error don't break out to run more
2096 double-colon rules: just return immediately.
2097 Fixes Savannah bug #7144.
2099 2005-02-27 Paul D. Smith <psmith@gnu.org>
2101 * misc.c (end_of_token): Make argument const.
2102 * make.h: Update prototype.
2104 * function.c (abspath, func_realpath, func_abspath): Use
2105 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2106 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2107 * read.c (record_files): Ditto.
2108 * variable.c (do_variable_definition): Ditto.
2110 * function.c (func_error): Create a new function $(info ...) that
2111 simply prints the message to stdout with no extras.
2112 (function_table_init): Add new function to the table.
2113 * NEWS: Add $(info ...) reference.
2114 * doc/make.texi (Make Control Functions): Document it.
2116 New feature: if the system supports symbolic links, and the user
2117 provides the -L/--check-symlink-time flag, then use the latest
2118 mtime between the symlink(s) and the target file.
2120 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2121 readlink(). If both are available, define MAKE_SYMLINKS.
2122 * main.c: New variable: check_symlink_flag.
2123 (usage): Add a line for -L/--check-symlink-times to the help string.
2124 (switches): Add -L/--check-symlink-times command line argument.
2125 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2126 print a warning and disable it again.
2127 * make.h: Declare check_symlink_flag.
2128 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2129 if the file is a symlink then check each link in the chain and
2130 choose the NEWEST mtime we find as the mtime for the file. The
2131 newest mtime might be the file itself!
2132 * NEWS: Add information about this new feature.
2133 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2135 Avoid core dumps described in Savannah bug # 12124:
2137 * file.c: New variable snapped_deps remember whether we've run
2138 snap_deps().
2139 (snap_deps): Set it.
2140 * filedef.h: Extern it.
2141 * read.c (record_files): Check snapped_deps; if it's set then
2142 we're trying to eval a new target/prerequisite relationship from
2143 within a command script, which we don't support. Fatal.
2145 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2147 Implementation of the .DEFAULT_TARGET special variable.
2149 * read.c (eval): If necessary, update default_target_name when
2150 reading rules.
2151 * read.c (record_files): Update default_target_file if
2152 default_target_name has changed.
2153 * main.c (default_target_name): Define.
2154 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2155 default_target_name is set use default_target_file as a root
2156 target to make.
2157 * filedef.h (default_target_name): Declare.
2158 * dep.h (free_dep_chain):
2159 * misc.c (free_dep_chain): Change to operate on struct nameseq
2160 and change name to free_ns_chain.
2161 * file.c (snap_deps): Update to use free_ns_chain.
2163 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2165 Implementation of the second expansion in explicit rules,
2166 static pattern rules and implicit rules.
2168 * read.c (eval): Refrain from chopping up rule's dependencies.
2169 Store them in a struct dep as a single dependency line. Remove
2170 the code that implements SySV-style automatic variables.
2172 * read.c (record_files): Adjust the code that handles static
2173 pattern rules to expand all percents instead of only the first
2174 one. Reverse the order in which dependencies are stored so that
2175 when the second expansion reverses them again they appear in
2176 the makefile order (with some exceptions, see comments in
2177 the code). Remove the code that implements SySV-style automatic
2178 variables.
2180 * file.c (snap_deps): Implement the second expansion and chopping
2181 of dependency lines for explicit rules.
2183 * implicit.c (struct idep): Define an auxiliary data type to hold
2184 implicit rule's dependencies after stem substitution and
2185 expansion.
2187 * implicit.c (free_idep_chain): Implement.
2189 * implicit.c (get_next_word): Implement helper function for
2190 parsing implicit rule's dependency lines into words taking
2191 into account variable expansion requests. Used in the stem
2192 splitting code.
2194 * implicit.c (pattern_search): Implement the second expansion
2195 for implicit rules. Also fixes bug #12091.
2197 * commands.h (set_file_variables): Declare.
2198 * commands.c (set_file_variables): Remove static specifier.
2200 * dep.h (free_dep_chain): Declare.
2201 * misc.c (free_dep_chain): Implement.
2203 * variable.h (variable_expand_for_file): Declare.
2204 * expand.c (variable_expand_for_file): Remove static specifier.
2206 * make.h (strip_whitespace): Declare.
2207 * function.c (strip_whitespace): Remove static specifier.
2209 2005-02-26 Paul D. Smith <psmith@gnu.org>
2211 * main.c (main): Check for ferror() when reading makefiles from stdin.
2212 Apparently some shells in Windows don't close pipes properly and
2213 require this check.
2215 2005-02-24 Jonathan Grant <jg@jguk.org>
2217 * configure.in: Add MinGW configuration options, and extra w32 code
2218 directory.
2219 * Makefile.am: Add MinGW configuration options, and extra w32 code
2220 directory.
2221 * main.c: Determine correct program string (after last \ without .exe).
2222 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2223 type fix x2
2224 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2225 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2226 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2227 environment support.
2229 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2231 * function.c (func_shell): When initializing error_prefix, check
2232 that reading file name is not null. This fixes long-standing
2233 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2235 2005-02-09 Paul D. Smith <psmith@gnu.org>
2237 * maintMakefile: Update the CVS download URL to simplify them.
2238 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2239 downloading the .texi files from Savannah now.
2241 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2243 * main.c (handle_non_switch_argument): Only add variables to
2244 command_variables if they're not already there: duplicate settings
2245 waste space and can be confusing to read.
2247 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2248 this header is never included by non-WINDOWS32 code, and it
2249 requires <config.h> to define which isn't always included first.
2251 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2252 testing MINGW32 versions.
2254 * main.c (log_working_directory): flush stdout to be sure the WD
2255 change is printed before any stderr messages show up.
2257 2005-02-01 Paul D. Smith <psmith@gnu.org>
2259 * maintMakefile (po_repo): Update the GNU translation site URL.
2261 2004-12-01 Paul D. Smith <psmith@gnu.org>
2263 * main.c (main): Change char* env_shell to struct variable shell_var.
2264 * variable.c (target_environment): Use new shell_var.
2266 2004-11-30 Paul D. Smith <psmith@gnu.org>
2268 * configure.in: The old way we avoided creating build.sh from
2269 build.sh.in before build.sh.in exists doesn't work anymore; we
2270 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2271 the help!). This also keeps automake from complaining.
2272 * Makefile.am (README): Add a dummy target so automake won't
2273 complain that this file doesn't exist when we checkout from CVS.
2274 * maintMakefile (.dep_segment): Rewrite this rule since newer
2275 versions of automake don't provide DEP_FILES.
2277 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2279 Implementation of `realpath' and `abspath' built-in functions.
2281 * configure.in: Check for realpath.
2282 * function.c (abspath): Return an absolute file name that does
2283 not contain any `.' or `..' components, nor repeated `/'.
2284 * function.c (func_abspath): For each name call abspath.
2285 * function.c (func_realpath): For each name call realpath
2286 from libc or delegate to abspath if realpath is not available.
2287 * doc/make.texi (Functions for File Names): Document new functions.
2288 * doc/make.texi (Quick Reference): Ditto.
2290 2004-11-28 Paul D. Smith <psmith@gnu.org>
2292 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2293 arguments. Fixes bug #10252.
2295 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2297 * main.c (main): Set SHELL to v_noexport by default. Remember the
2298 original environment setting of SHELL in the env_shell variable.
2299 * main.h: Export new env_shell variable.
2300 * variable.c (target_environment): If we find a v_noexport
2301 variable for SHELL, add a SHELL variable with the env_shell value.
2302 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2303 * doc/make.texi (Variables/Recursion): Ditto.
2305 2004-11-28 Paul D. Smith <psmith@gnu.org>
2307 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2308 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2309 Patch by Alessandro Vesely.
2311 2004-11-12 Paul D. Smith <psmith@gnu.org>
2313 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2314 the command line if it's inside a string.
2315 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2317 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2319 * function.c (func_lastword): New function: return last word
2320 from the list of words.
2321 * doc/make.texi: Document $(lastword ). Fix broken links in
2322 Quick Reference section.
2324 2004-10-06 Paul D. Smith <psmith@gnu.org>
2326 Apply patch from Alessandro Vesely, provided with bug # 9748.
2327 Fix use of tmpnam() to work with Borland C.
2329 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2330 construction of a temporary filename, and call new function
2331 create_batch_filename().
2332 (create_batch_filename) [WINDOWS32]: New function to create a
2333 temporary filename.
2335 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2337 * read.c (record_target_var): Expand simple pattern-specific
2338 variable.
2339 * variable.c (initialize_file_variables): Do not expand simple
2340 pattern-specific variable.
2342 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2344 * remake.c (update_file_1): When rebuilding makefiles inherit
2345 dontcare flag from a target that triggered update.
2347 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2349 * variable.c (initialize_file_variables): Mark pattern-specific
2350 variable as a per-target and copy export status.
2352 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2354 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2356 * implicit.c (pattern_search): When considering an implicit rule's
2357 prerequisite check that it is actually a target rather then
2358 just an entry in the file hashtable.
2360 2004-09-21 Paul D. Smith <psmith@gnu.org>
2362 * read.c (readstring): Fix some logic errors in backslash handling.
2363 (eval): Remove some unnecessary processing in buffer handling.
2364 (record_target_var): Assert that parse_variable_definition() succeeded.
2365 Reported by: Markus Mauhart <qwe123@chello.at>.
2367 * misc.c: Removed the sindex() function. All instances of this
2368 function were trivially replaceable by the standard strstr()
2369 function, and that function will always have better (or certainly
2370 no worse) performance than the very simple-minded algorithm
2371 sindex() used. This can matter with complex makefiles.
2372 * make.h: Remove the prototype for sindex().
2373 * function.c (subst_expand): Convert sindex() call to strstr().
2374 This means we no longer need to track the TLEN value so remove that.
2375 (func_findstring): Convert sindex() to strstr().
2376 * commands.c (chop_commands): Convert sindex() calls to strstr().
2377 Suggested by: Markus Mauhart <qwe123@chello.at>.
2379 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2380 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2381 If SHELL is set to CMD.EXE then assume it's batch-mode and
2382 non-unixy. I wrote the code differently from the patch, though,
2383 to make it safer. This also resolves bug #9174.
2385 2004-09-20 Paul D. Smith <psmith@gnu.org>
2387 * expand.c (variable_expand_string): Modify to invoke
2388 patsubst_expand() instead of subst_expand(); the latter didn't
2389 handle suffix patterns correctly.
2390 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2391 was used only from variable_expand_string() and is no longer used
2392 there.
2393 (func_subst): Ditto, on call to subst_expand().
2394 (patsubst_expand): Require the percent pointers to point to the
2395 character after the %, not to the % itself.
2396 * read.c (record_files): New call criteria for patsubst_expand().
2397 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2398 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2400 2004-09-19 Paul D. Smith <psmith@gnu.org>
2402 * function.c (subst_expand): Fix a check in by_word: look for a
2403 previous blank if we're beyond the beginning of the string, not
2404 the beginning of the word.
2405 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2407 2004-05-16 Paul D. Smith <psmith@gnu.org>
2409 * remake.c (update_goal_chain): Change the argument specifying
2410 whether we're rebuilding makefiles to be a global variable,
2411 REBUILDING_MAKEFILES.
2412 (complain): Extract the code that complains about no rules to make
2413 a target into a separate function.
2414 (update_file_1): If we tried to rebuild a file during the makefile
2415 rebuild phase and it was dontcare, then no message was printed.
2416 If we then try to build the same file during the normal build,
2417 print a message this time.
2418 (remake_file): Don't complain about un-remake-able files when
2419 we're rebuilding makefiles.
2421 2004-05-11 Paul D. Smith <psmith@gnu.org>
2423 * job.c (construct_command_argv_internal): OS/2 patches from
2424 Andreas Buening <andreas.buening@nexgo.de>.
2426 2004-05-10 Paul D. Smith <psmith@gnu.org>
2428 * remake.c (update_file): Don't walk the double-colon chain unless
2429 this is a double-colon rule. Fix suggested by Boris Kolpackov
2430 <boris@kolpackov.net>.
2432 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2433 * readme.vms: New section describing OpenVMS support and issues.
2434 * default.c (default_variables): Add support for IA64.
2435 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2436 without some privilege aborts make with the error
2437 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2438 pressing Ctrl+Y and the input device is no terminal. The change
2439 catches this error and just continues.
2441 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2443 2004-04-25 Paul D. Smith <psmith@gnu.org>
2445 * commands.c (set_file_variables): Set $< properly in the face of
2446 order-only prerequisites.
2447 Patch from Boris Kolpackov <boris@kolpackov.net>
2449 2004-04-21 Bob Byrnes <byrnes@curl.com>
2451 * main.c (main): Notice failures to remake makefiles.
2453 2004-03-28 Paul D. Smith <psmith@gnu.org>
2455 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2457 * job.c: No default shell for RISC OS.
2458 (load_too_high): Hard-code the return to 1.
2459 (construct_command_argv_internal): No sh_chars or sh_cmds.
2460 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2462 2004-03-20 Paul D. Smith <psmith@gnu.org>
2464 * variable.c (do_variable_definition): Don't append from the
2465 global set if a previous non-appending target-specific variable
2466 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2467 (with fix).
2469 * expand.c (reference_variable): Don't give up on variables with
2470 no value that have the target-specific append flag set: they might
2471 have a value after all. Reported by Oliver Schmidt
2472 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2473 <nikulin@dx1cmd.inp.nsk.su>.
2475 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2476 refer to absolute pathnames in directories that don't exist: some
2477 portion of the makefile could create those directories before we
2478 match the pattern. Fixes bugs #775 and #108.
2480 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2482 * main.c (main): Free makefile_mtimes if we have any.
2483 * README.W32.template: Update documentation for the current status
2484 of the MS-Windows port.
2485 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2486 environment variable is sometimes already defined which causes the
2487 build to fail.
2488 * main.c (debug_signal_handler): Only define this function if
2489 SIGUSR1 is available.
2491 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2493 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2494 * README.OS2.template: Documentation updates.
2495 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2496 link line for safety.
2497 * maintMakefile (build.sh.in): Remove an extraneous ")".
2498 * job.c (child_execute_job): Close saved FDs.
2499 * job.c (exec_command) [OS/2]: exec_command(): If the command
2500 can't be exec'ed and if the shell is not Unix-sh, then try again
2501 with argv = { "cmd", "/c", ... }. Normally, this code is never
2502 reached for the cmd shell unless the command really doesn't exist.
2503 (construct_command_argv_internal) [OS/2]: The code for cmd
2504 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2505 The CMD builtin commands are case insensitive so use strcasecmp().
2507 2004-03-19 Paul D. Smith <psmith@gnu.org>
2509 * read.c (do_define): Re-order line counter increment so the count
2510 is accurate (we were losing one line per define). Reported by
2511 Dave Yost <Dave@Yost.com>.
2513 2004-03-06 Paul D. Smith <psmith@gnu.org>
2515 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2516 compiler.
2517 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2518 * misc.c (message,error,fatal): Ditto.
2519 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2520 * config.h.W32.template: Ditto.
2521 * config.h-vms.template: Ditto.
2522 * config.ami.template: Ditto.
2524 2004-03-04 Paul D. Smith <psmith@gnu.org>
2526 * README.template: Add a note about broken /bin/sh on SunOS
2527 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2529 * misc.c (message, error, fatal): Don't use "..." if we're using
2530 varargs. ansi2knr should handle this but it doesn't work: it
2531 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2532 done. On many systems (SunOS for example) va_dcl is a #define.
2533 So, force the use of the non-"..." version on pre-ANSI compilers.
2535 * maintMakefile (sign-dist): Create some rules to help automate
2536 the new GNU ftp upload method.
2538 2004-02-24 Paul D. Smith <psmith@gnu.org>
2540 * config.h.W32.template: Add HAVE_STDARG_H
2541 * config.h-vms.template: Ditto.
2542 * config.ami.template: Ditto.
2544 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2546 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2547 * build_w32.bat: Remove extra "+".
2549 2004-02-23 Paul D. Smith <psmith@gnu.org>
2551 * make.h: Create an UNUSED macro to mark unused parameters.
2552 * (many): Clean up warnings by applying UNUSED, fixing
2553 signed/unsigned incompatibilities, etc.
2555 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2556 autoconf warnings.
2557 * filedef.h: Name the command_state enumeration.
2558 * file.c (set_command_state): Use the enumeration in the function
2559 argument.
2561 * configure.in: Explicitly set SET_MAKE to empty, to disable
2562 MAKE=make even when no make already exists. Fix bug #3823.
2564 2004-02-22 Paul D. Smith <psmith@gnu.org>
2566 * maintMakefile: Perl script to clean up all non-CVS files. Use
2567 it on all the subdirectories for the cvs-clean target.
2569 * main.c (decode_switches): Require non-empty strings for all our
2570 string command-line options. Fixes Debian bug # 164165.
2572 * configure.in: Check for stdarg.h and varargs.h.
2573 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2574 for printing messages.
2575 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2576 (message): Ditto.
2577 (error): Ditto.
2578 (fatal): Ditto.
2580 A number of patches for OS/2 support from Andreas Buening
2581 <andreas.buening@nexgo.de>:
2583 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2584 disable the SIGCHLD handler.
2585 (reap_children) [OS/2]: Remove special handling of job_rfd.
2586 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2587 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2588 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2589 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2590 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2591 systems.
2593 2004-02-21 Paul D. Smith <psmith@gnu.org>
2595 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2596 <mail@kristov.de> reports that if process_begin() fails we don't
2597 handle the error condition correctly in all cases.
2598 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2599 to have a newline on the message.
2601 * job.c (construct_command_argv_internal): Add "test" to UNIX
2602 sh_cmds[]. Fixes Savannah bug # 7606.
2604 2004-02-04 Paul D. Smith <psmith@gnu.org>
2606 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2607 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2608 Hartmut Becker <Hartmut.Becker@hp.com>.
2610 2004-01-21 Paul D. Smith <psmith@gnu.org>
2612 * job.c (load_too_high): Implement an algorithm to control the
2613 "thundering herd" problem when using -l to control job creation
2614 via the load average. The system only recomputes the load once a
2615 second but we can start many jobs in a second. To solve this we
2616 keep track of the number of jobs started in the last second and
2617 apply a weight to try to guess what a correct load would be.
2618 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2619 Also fixes bug #4693.
2620 (reap_children): Decrease the job count for this second.
2621 (start_job_command): Increase the job count for this second.
2623 * read.c (conditional_line): Expand the text after ifn?def before
2624 checking to see if it's a single word. Fixes bug #7257.
2626 2004-01-09 Paul D. Smith <psmith@gnu.org>
2628 * file.c (print_file): Recurse to print all targets in
2629 double-colon rules. Fixes bug #4518, reported (with patch) by
2630 Andrew Chatham <chatham@google.com>.
2632 2004-01-07 Paul D. Smith <psmith@gnu.org>
2634 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2635 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2636 AC_FUNC_SETVBUF_REVERSED.
2638 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2639 (MAKE Variable): Fix Savannah bug #4898.
2641 * job.c (construct_command_argv_internal): Add "!" to the list of
2642 shell escape chars. POSIX sh allows it to appear before a
2643 command, to negate the exit code. Fixes bug #6404.
2645 * implicit.c (pattern_search): When matching an implicit rule,
2646 remember which dependencies have the ignore_mtime flag set.
2647 Original fix provided in Savannah patch #2349, by Benoit
2648 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2650 2003-11-22 Paul D. Smith <psmith@gnu.org>
2652 * README.W32.template (Outputs): Clarification on -j with
2653 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2654 <jg-make@jguk.org>.
2656 2003-11-02 Paul D. Smith <psmith@gnu.org>
2658 * function.c (func_if): Strip all the trailing whitespace from the
2659 condition, then don't expand it. Fixed bug # 5798.
2661 * expand.c (recursively_expand_for_file): If we're expanding a
2662 variable with no file context, then use the variable's context.
2663 Fixes bug # 6195.
2665 2003-10-21 Paul D. Smith <psmith@gnu.org>
2667 * main.c (log_working_directory): Add newlines to printf()s.
2669 * README.cvs: Add a note to ignore warnings during autoreconf.
2671 * maintMakefile (po_repo): Set a new URL for PO file updates.
2672 (get-config/config.guess get-config/config.sub): Get these files
2673 from the Savannah config project instead of ftp.gnu.org.
2675 2003-10-05 Paul Eggert <eggert@twinsun.com>
2677 * main.c (main): Avoid potential subscript error if environ has
2678 short strings.
2680 2003-08-22 Paul D. Smith <psmith@gnu.org>
2682 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2683 systems which don't yet implement the C89 standard :-/.
2685 2003-07-18 Paul D. Smith <psmith@gnu.org>
2687 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2688 [WINDOWS32]: Initialize hash.
2690 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2692 * dir.c (read_dirstream): Provide a workaround for broken versions of
2693 the MinGW dirent structure.
2695 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2697 * w32/include/dirent.h: Add __MINGW32__ filter.
2699 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2701 * make.h: Add global declaration of *make_host.
2702 * main.c (print_usage): Remove local declaration of *make_host.
2703 (print_version): Display "This program built for ..." after Copyright
2704 notice.
2706 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2708 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2709 execution of "makeinfo --html make.texi".
2711 2003-04-30 Paul D. Smith <psmith@gnu.org>
2713 * build.template: Make some changes to maybe allow this script to
2714 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2716 * README.OS2.template: New file for OS/2 support. Original
2717 contributed by Andreas Buening.
2718 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2719 DOS-style paths.
2721 2003-04-19 Paul D. Smith <psmith@gnu.org>
2723 Fix bug #1405: allow a target to match multiple pattern-specific
2724 variables.
2726 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2727 variable.c, where they've always belonged.
2728 * rule.h: Move the prototypes and struct pattern_var as well.
2729 * variable.c (initialize_file_variables): Invoke
2730 lookup_pattern_var() in a loop, until no more matches are found.
2731 If a match is found, create a new variable set for the target's
2732 pattern variables. Then merge the contents of each matching
2733 pattern variable set into the target's pattern variable set.
2734 (lookup_pattern_var): Change this function to be usable
2735 in a loop. It takes a starting position: if NULL, start at the
2736 beginning; if non-NULL, start with the pattern variable after that
2737 position, and return the next matching pattern.
2738 (create_pattern_var): Create a unique instance of
2739 pattern-specific variables for every definition in the makefile.
2740 Don't combine the same pattern together. This allows us to
2741 process the variable handling properly even when the same pattern
2742 is used multiple times.
2743 (parse_variable_definition): New function: break out the parsing
2744 of a variable definition line from try_variable_definition.
2745 (try_variable_definition): Call parse_variable_definition to
2746 parse.
2747 (print_variable_data_base): Print out pattern-specific variables.
2748 * variable.h (struct variable): Remember when a variable is
2749 conditional. Also remember its flavor.
2750 (struct pattern_var): Instead of keeping a variable set, we just
2751 keep a single variable for each pattern.
2752 * read.c (record_target_var): Each pattern variable contains only a
2753 single variable, not a set, so create it properly.
2754 * doc/make.texi (Pattern-specific): Document the new behavior.
2756 2003-04-17 Paul D. Smith <psmith@gnu.org>
2758 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2759 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2760 file/directory naming rules for VMS so I can't tell whether this
2761 is correct or not.
2763 2003-04-09 Paul D. Smith <psmith@gnu.org>
2765 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2766 DOS-style pathnames: backslash separators and drive specifiers.
2768 2003-03-28 Paul D. Smith <psmith@gnu.org>
2770 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2771 the intermediate flag on all targets. Fixes bug #2515.
2773 2003-03-24 Paul D. Smith <psmith@gnu.org>
2775 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2776 Upgrade to autoconf 2.57 and automake 1.7.3.
2778 * job.c: More OS/2 changes from Andreas Buening.
2780 * file.c (print_file): Fix variable initialization.
2781 Fixes bug #2892.
2783 * remake.c (notice_finished_file):
2785 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2786 some calls (like readdir()) return NULL in valid situations
2787 without resetting errno. Fixes bug #2846.
2789 2003-02-25 Paul D. Smith <psmith@gnu.org>
2791 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2793 * job.c (_is_unixy_shell) [OS/2]: New function.
2794 Set default shell to /bin/sh.
2795 (reap_children): Close the job_rfd pipe here since we don't use a
2796 SIGCHLD handler.
2797 (set_child_handler_action_flags): define this to empty on OS/2.
2798 (start_job_command): Close the jobserver pipe and use
2799 child_execute_job() instead of fork/exec.
2800 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2801 rather than exec'ing, then reconfigure stdin/stdout.
2802 (exec_command): Rewrite to use spawn instead of exec. Return the
2803 PID of the child.
2805 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2806 in DOS. Handle the TEMP environment variable as in DOS. Don't
2807 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2808 use -j in DOS mode. Use child_execute_job() instead of
2809 exec_command().
2811 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2812 spawn() instead.
2814 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2815 prototypes that return values.
2817 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2819 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2820 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2821 for OS/2.
2822 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2823 DOS paths.
2825 2003-02-24 Paul D. Smith <psmith@gnu.org>
2827 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2828 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2829 (child_execute_job) [VMS]: Handle error status properly.
2830 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2832 * function.c (func_shell): Use EINTRLOOP() while reading from the
2833 subshell pipe (Fixes bug #2502).
2834 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2835 jobserver pipe.
2836 * main.c (main): Ditto.
2838 2003-01-30 Paul D. Smith <psmith@gnu.org>
2840 * read.c (eval): eval() was not fully reentrant, because the
2841 collapsed buffer was static. Change it to be an automatic
2842 variable so that eval() can be invoked recursively.
2843 Fixes bug # 2238.
2844 (eval): Apply patch # 1022: fix memory reference error on long
2845 target-specific variable lines.
2846 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2848 * function.c (check_numeric): Combine the is_numeric() function
2849 into this function, since it's only called from one place.
2850 Constify this function. Have it print the incorrect string in the
2851 error message. Fixes bug #2407.
2852 (strip_whitespace): Constify.
2853 (func_if): Constify.
2854 * expand.c (expand_argument): Constify.
2856 2003-01-29 Paul D. Smith <psmith@gnu.org>
2858 Fix bug # 2169, also reported by other people on various systems.
2860 * make.h: Some systems, such as Solaris and PTX, do not fully
2861 implement POSIX-compliant SA_RESTART functionality; important
2862 system calls like stat() and readdir() can still fail with EINTR
2863 even if SA_RESTART has been set on the signal handler. So,
2864 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2865 EINTR for system calls which return -1 or 0 (NULL), respectively,
2866 on error.
2867 Also, remove the old atomic_stat()/atomic_readdir() and
2868 HAVE_BROKEN_RESTART handling.
2870 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2872 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2873 * remake.c (touch_file): Ditto.
2875 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2876 * read.c (construct_include_path): Ditto.
2877 * remake.c (name_mtime): Ditto.
2878 * vpath.c (selective_vpath_search): Ditto.
2879 * dir.c (find_directory): Ditto.
2880 (local_stat): Ditto.
2881 (find_directory): Use ENULLLOOP() to wrap opendir().
2882 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2884 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2885 atomic_readdir() handling.
2887 2003-01-22 Paul D. Smith <psmith@gnu.org>
2889 * function.c (func_call): Fix Bug #1744. If we're inside a
2890 recursive invocation of $(call ...), mask any of the outer
2891 invocation's arguments that aren't used by this one, so that this
2892 invocation doesn't "inherit" them accidentally.
2894 2002-12-05 Paul D. Smith <psmith@gnu.org>
2896 * function.c (subst_expand): Valery Khamenia reported a
2897 pathological performance hit when doing substitutions on very
2898 large values with lots of words: turns out we were invoking
2899 strlen() a ridiculous number of times. Instead of having each
2900 call to sindex() call strlen() again, keep track of how much of
2901 the text we've seen and pass the length to sindex().
2903 2002-11-19 Paul D. Smith <psmith@gnu.org>
2905 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2908 2002-11-16 Paul D. Smith <psmith@gnu.org>
2910 * NMakefile.template (OBJS): Add hash.c object file.
2911 * SMakefile.template (srcs): Ditto.
2912 * Makefile.ami (objs): Ditto.
2913 * build_w32.bat: Ditto.
2915 * Makefile.DOS.template: Remove extra dependencies.
2917 2002-10-25 Paul D. Smith <psmith@gnu.org>
2919 * expand.c (install_variable_buffer): New function. Install a new
2920 variable_buffer context and return the previous one.
2921 (restore_variable_buffer): New function. Free the current
2922 variable_buffer context and put a previously saved one back.
2923 * variable.h: Prototypes for {install,restore}_variable_buffer.
2924 * function.c (func_eval): Push a new variable_buffer context
2925 before we eval, then restore the old one when we're done.
2926 Fixes Bug #1517.
2928 * read.c (install_conditionals): New function. Install a new
2929 conditional context and return the previous one.
2930 (restore_conditionals): New function. Free the current
2931 conditional context and put a previously saved one back.
2932 (eval): Use the {install,restore}_conditionals for "include"
2933 handling.
2934 (eval_buffer): Use {install,restore}_conditionals to preserve the
2935 present conditional state before we evaluate the buffer.
2936 Fixes Bug #1516.
2938 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2939 and $(value ...).
2940 (Recursion): Add a variable index entry for CURDIR.
2942 * README.cvs: Update to appropriate versions.
2943 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2944 don't need to copy loadavg.c: automake is smart enough to create
2945 it for me. Still have a bug in automake related to ansi2knr tho.
2947 2002-10-14 Paul D. Smith <psmith@gnu.org>
2949 * remake.c (notice_finished_file): Only touch targets if they have
2950 at least one command (as per POSIX). Resolve Bug #1418.
2952 * *.c: Convert to using ANSI C-style function definitions.
2953 * Makefile.am: Enable the ansi2knr feature of automake.
2954 * configure.in: ditto.
2956 2002-10-13 Paul D. Smith <psmith@gnu.org>
2958 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2959 for automatic variable values like $^, etc. In the case of very
2960 large lists of prerequisites this causes problems. Instead reuse
2961 a static buffer (resizeable) for each variable.
2963 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2964 target-specific variable definitions. Check for it and set an
2965 "exported" flag.
2966 (record_target_var): Set the export field to v_export if the
2967 "exported" flag is set.
2968 * doc/make.texi (Target-specific): Document the ability to use
2969 "export".
2971 * doc/make.texi: Change the name of the section on automatic
2972 variables from "Automatic" to "Automatic Variables". Added text
2973 clarifying the scope of automatic variables.
2975 2002-10-04 Paul D. Smith <psmith@gnu.org>
2977 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2978 as () braces.
2979 (record_files): Ditto.
2981 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2982 the search for the '=' to only within the enclosing parens.
2984 2002-10-03 Paul D. Smith <psmith@gnu.org>
2986 Version 3.80 released.
2988 * dir.c: Change hash functions to use K&R function definition style.
2989 * function.c: Ditto.
2990 * read.c: Ditto.
2991 * variable.c: Ditto.
2993 Update to automake 1.7.
2995 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2996 (pdf): Remove this target as automake now provides one.
2998 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3000 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3002 * makefile.com: Updates for GNU make 3.80.
3003 * makefile.vms: Ditto.
3005 2002-09-23 Paul D. Smith <psmith@gnu.org>
3007 * read.c (enum make_word_type): Remove w_comment.
3008 (get_next_mword): Don't treat comment characters as special; where
3009 this function is used we will never see a comment (it's stripped
3010 before we get here) and treating comments specially means that
3011 targets like "foo\#bar" aren't handled properly.
3013 2002-09-18 Paul D. Smith <psmith@gnu.org>
3015 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3017 * read.c (eval): Expansion of arguments to export/unexport was
3018 ignoring all arguments after the first one. Change the algorithm
3019 to expand the whole line once, then parse the results.
3021 2002-09-17 Paul D. Smith <psmith@gnu.org>
3023 Fix Bug #940 (plus another bug I found while looking at this):
3025 * read.c (record_target_var): enter_file() will add a new entry if
3026 it's a double-colon target: we don't want to do that in this
3027 situation. Invoke lookup_file() and only enter_file() if it does
3028 not already exist. If the file we get back is a double-colon then
3029 add this variable to the "root" double-colon target.
3031 * variable.c (initialize_file_variables): If this file is a
3032 double-colon target but is not the "root" target, then initialize
3033 the root and make the root's variable list the parent of our
3034 variable list.
3036 2002-09-13 Paul D. Smith <psmith@gnu.org>
3038 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3040 * hash.c (round_up_2): Get rid of a warning.
3042 2002-09-12 Paul D. Smith <psmith@gnu.org>
3044 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3045 so it doesn't complain about getloadavg.c.
3047 * commands.c (set_file_variables): Make sure we always alloca() at
3048 least 1 character for the value of $? (for '\0').
3050 2002-09-11 Paul D. Smith <psmith@gnu.org>
3052 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3053 macro to use RESULT instead of the incorrect _RESULT_.
3055 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3056 and atomic_readdir(). We need to #include dirent.h to get this to
3057 work.
3058 * misc.c (atomic_readdir): Fix typos.
3060 2002-09-10 Paul D. Smith <psmith@gnu.org>
3062 * read.c (eval): Expand variable lists given to export and
3063 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3064 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3066 * doc/make.texi (Variables/Recursion): Document this.
3067 (Conditional Syntax): And here.
3069 2002-09-09 Paul D. Smith <psmith@gnu.org>
3071 * configure.in: Check for memmove().
3073 2002-09-07 Paul D. Smith <psmith@gnu.org>
3075 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3076 Michael Sterrett <msterret@coat.com> reports that while it has
3077 SA_RESTART, it does not work properly.
3079 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3080 that invokes stat() and loops to do it again if it returns EINTR.
3081 (atomic_readdir): Ditto, with readdir().
3083 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3084 and readdir() to atomic_stat() and atomic_readdir().
3086 2002-09-04 Paul D. Smith <psmith@gnu.org>
3088 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3089 reports that GNU make sometimes doesn't recognize that targets can
3090 be made, when directories can be created as prerequisites. He
3091 reports that changing the order of predicates in the DEP->changed
3092 flag test so that lookup_file() is always performed, solves this
3093 problem.
3095 2002-08-08 Paul D. Smith <psmith@gnu.org>
3097 * configure.in: Require a newer version of gettext.
3099 * misc.c (perror_with_name): Translate the format string (for
3100 right-to-left language support).
3101 (pfatal_with_name): Ditto.
3103 * main.c: Create a static array of strings to store the usage
3104 text. This is done to facilitate translations.
3105 (struct command_switch): Remove argdesc and description fields.
3106 (switches): Remove values for obsolete fields.
3107 (print_usage): Print each element of the usage array.
3109 * hash.c: Change function definitions to be K&R style.
3111 2002-08-02 Paul D. Smith <psmith@gnu.org>
3113 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3114 this one because it's too hard to get right. We'll look at it for
3115 a future release.
3116 * main.c (main): Don't create the .TARGETS variable.
3117 * variable.c (handle_special_var): Don't handle .TARGETS.
3119 2002-08-01 Paul D. Smith <psmith@gnu.org>
3121 * main.c (switches): Add a new option, -B (--always-make). If
3122 specified, make will rebuild all targets that it encounters even
3123 if they don't appear to be out of date.
3124 (always_make_flag): New flag.
3125 * make.h: Extern always_make_flag.
3126 * remake.c (update_file_1): Check always_make_flag; if it's set we
3127 will always rebuild any target we can, even if none of its
3128 prerequisites are newer.
3129 * NEWS: Mention it.
3131 * doc/make.texi (Shell Function): Make it clear that make
3132 variables marked as "export" are not passed to instances of the
3133 shell function.
3135 Add new introspection variable .VARIABLES and .TARGETS.
3137 * variable.c (handle_special_var): New function. If the variable
3138 reference passed in is "special" (.VARIABLES or .TARGETS),
3139 calculate the new value if necessary. .VARIABLES is handled here:
3140 walk through the hash of defined variables and construct a value
3141 which is a list of the names. .TARGETS is handled by
3142 build_target_list().
3143 (lookup_variable): Invoke handle_special_var().
3144 * file.c (build_target_list): Walk through the hask of known files
3145 and construct a list of the names of all the ones marked as
3146 targets.
3147 * main.c (main): Initialize them to empty (and as simple variables).
3148 * doc/make.texi (Special Variables): Document them.
3149 * NEWS: Mention them.
3151 * variable.h (struct variable): Add a new flag "exportable" which
3152 is true if the variable name is valid for export.
3153 * variable.c (define_variable_in_set): Set "exportable" when a new
3154 variable is defined.
3155 (target_environment): Use the "exportable" flag instead of
3156 re-checking the name here... an efficiency improvement.
3158 2002-07-31 Paul D. Smith <psmith@gnu.org>
3160 * config.h-vms.template: Updates to build on VMS. Thanks to
3161 Brian_Benning@aksteel.com for helping verify the build.
3162 * makefile.com: Build the new hash.c file.
3163 * hash.h: Use strcpmi(), not stricmp(), in the
3164 HAVE_CASE_INSENSITIVE_FS case.
3166 2002-07-30 Paul D. Smith <psmith@gnu.org>
3168 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3169 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3170 Reported by <Brian_Benning@aksteel.com>.
3172 2002-07-10 Paul D. Smith <psmith@gnu.org>
3174 * variable.c (pop_variable_scope): Remove variable made unused by
3175 new hash infrastructure.
3176 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3177 comparisons as well as name comparisons.
3178 * variable.h: Add a prototype for new hash_init_function_table().
3179 * file.c (lookup_file): Remove variables made unused by new hash
3180 infrastructure.
3181 * dir.c (directory_contents_hash_2): Missing return of hash value.
3182 (dir_contents_file_exists_p): Remove variables made unused by new
3183 hash infrastructure.
3186 Installed Greg McGary's integration of the hash functions from the
3187 GNU id-utils package:
3189 2002-07-10 Greg McGary <greg@mcgary.org>
3191 * scripts/functions/filter-out: Add literals to to the
3192 pattern space in order to add complexity, and trigger
3193 use of an internal hash table. Fix documentation strings.
3194 * scripts/targets/INTERMEDIATE: Reverse order of files
3195 passed to expected `rm' command.
3197 2002-07-10 Greg McGary <greg@mcgary.org>
3199 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3200 * hash.c: New file, taken from id-utils.
3201 * hash.h: New file, taken from id-utils.

3211 (init_hash_files): New function decl.
3213 * ar.c (ar_name): Delay call to strlen until needed.
3214 * main.c (initialize_global_hash_tables): New function.
3215 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3216 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3217 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
3219 * dir.c (hash.h): New #include.
3220 (struct directory_contents) [next, files]: Remove members.
3221 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

3231 (find_directory): Use new hash table package.
3232 (dir_contents_file_exists_p): Likewise.
3233 (file_impossible): Likewise.
3234 (file_impossible_p): Likewise.
3235 (print_dir_data_base): Likewise.
3236 (open_dirstream): Likewise.
3237 (read_dirstream): Likewise.
3238 (hash_init_directories): New function.
3240 * file.c (hash.h): New #include.
3241 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
3242 (files): Change type to `struct hash_table'.
3243 (lookup_file): Use new hash table package.
3244 (enter_file): Likewise.
3245 (remove_intermediates): Likewise.
3246 (snap_deps): Likewise.
3247 (print_file_data_base): Likewise.
3249 * function.c
3250 (function_table_entry_hash_1, function_table_entry_hash_2,
3251 function_table_entry_hash_cmp): New functions.
3252 (lookup_function): Remove `table' argument.
3253 Use new hash table package.
3254 (struct a_word) [chain, length]: New members.
3255 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3256 (struct a_pattern): New struct.
3257 (func_filter_filterout): Pass through patterns noting boundaries
3258 and '%', if present. Note a_word length. Use a hash table if
3259 arglists are large enough to justify cost.
3260 (function_table_init): Renamed from function_table.
3261 (function_table): Declare as `struct hash_table'.
3262 (FUNCTION_TABLE_ENTRIES): New constant.
3263 (hash_init_function_table): New function.
3265 * read.c (hash.h): New #include.
3266 (read_makefile): Pass char constants to find_char_unquote.
3267 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3268 (uniquize_deps): Use hash table to efficiently identify duplicates.
3269 (find_char_unquote): Accept two char-constant stop chars, rather
3270 than a string constant, avoiding zillions of calls to strchr.
3271 Tighten inner search loops to test only for desired delimiters.
3273 * variable.c (variable_hash_1, variable_hash_2,
3274 variable_hash_cmp): New functions.

3286 (target_environment): Likewise.
3287 (print_variable_set): Likewise.
3289 2002-07-10 Paul D. Smith <psmith@gnu.org>
3291 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3292 prerequisite list. A real SysV make will expand the entire
3293 prerequisites list _twice_: we don't do that as it's a big
3294 backward-compatibility problem. We only replace those specific
3295 variables.
3297 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3298 references left in the list of prerequisites. Check for .POSIX as
3299 we record targets, so we can disable non-POSIX behavior while
3300 reading makefiles as well as running them.
3301 (eval): Check the prerequisite list to see if we have anything
3302 that looks like a SysV prerequisite variable reference.
3304 2002-07-09 Paul D. Smith <psmith@gnu.org>
3306 * doc/make.texi (Prerequisite Types): Add a new section describing
3307 order-only prerequisites.
3309 * read.c (uniquize_deps): If we have the same file as both a
3310 normal and order-only prereq, get rid of the order-only prereq,
3311 since the normal one supersedes it.
3313 2002-07-08 Paul D. Smith <psmith@gnu.org>
3315 * AUTHORS: Added Greg McGary to the AUTHORS file.
3316 * NEWS: Blurbed order-only prerequisites.
3317 * file.c (print_file): Show order-only deps properly when printing
3318 the database.
3320 * maintMakefile: Add "update" targets for wget'ing the latest
3321 versions of various external files. Taken from Makefile.maint in
3322 autoconf, etc.
3324 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3325 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3327 2002-07-07 Paul D. Smith <psmith@gnu.org>
3329 * po/*.po: Remove. We'll use wget to retrieve them at release
3330 time.
3332 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3333 rather than a shell you get an exception. Make sure we look up
3334 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3336 * remake.c (notice_finished_file): Fix handling of -t flag.
3337 Patch provided by Henning Makholm <henning@makholm.net>.
3339 * implicit.c (pattern_search): Some systems apparently run short
3340 of stack space, and using alloca() in this function caused an
3341 overrun. I modified it to use xmalloc() on the two variables
3342 which seemed like they might get large. Fixes Bug #476.
3344 * main.c (print_version): Update copyright notice to conform with
3345 GNU standards.
3346 (print_usage): Update help output.
3348 * function.c (func_eval): Create a new make function, $(eval
3349 ...). Expand the arguments, put them into a buffer, then invoke
3350 eval_buffer() on the resulting string.
3351 (func_quote): Create a new function, $(quote VARNAME). Inserts
3352 the value of the variable VARNAME without expanding it any
3353 further.
3355 * read.c (struct ebuffer): Change the linebuffer structure to an
3356 "eval buffer", which can be either a file or a buffer.
3357 (eval_makefile): Move the code in the old read_makefile() which
3358 located a makefile into here: create a struct ebuffer with that
3359 information. Have it invoke the new function eval() with that
3360 ebuffer.
3361 (eval_buffer): Create a new function that creates a struct ebuffer
3362 that holds a string buffer instead of a file. Have it invoke
3363 eval() with that ebuffer.
3364 (eval): New function that contains the guts of the old
3365 read_makefile() function: this function parses makefiles. Obtains
3366 data to parse from the provided ebuffer. Some modifications to
3367 make the flow of the function cleaner and clearer. Still could
3368 use some work here...
3369 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3370 contents of the define/endef variable from the ebuffer.
3371 (readstring): Read the next line from a string-style ebuffer.
3372 (readline): Read the next line from an ebuffer. If it's a string
3373 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3374 from the file.
3376 * dep.h (eval_buffer): Prototype eval_buffer();
3378 * variable.c (do_variable_definition): Make sure that all
3379 non-target-specific variables are registered in the global set.
3380 If we're invoked from an $(eval ...) we might be inside a $(call
3381 ...) or other function which has pushed a variable scope; we still
3382 want to define our variables from evaluated makefile code in the
3383 global scope.
3385 2002-07-03 Greg McGary <greg@mcgary.org>
3387 * dep.h (struct dep) [ignore_mtime]: New member.
3388 [changed]: convert to a bitfield.
3389 * implicit.c (pattern_search): Zero ignore_mtime.
3390 * main.c (main, handle_non_switch_argument): Likewise.
3391 * rule.c (convert_suffix_rule): Likewise.
3392 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3393 (read_makefile): Parse '|' in prerequisite list.
3394 (uniquize_deps): Consider ignore_mtime when comparing deps.
3395 * remake.c (update_file_1, check_dep): Don't force remake for
3396 dependencies that have d->ignore_mtime.
3397 * commands.c (FILE_LIST_SEPARATOR): New constant.
3398 (set_file_variables): Don't include a
3399 prerequisite in $+, $^ or $? if d->ignore_mtime.
3400 Define $|.
3402 2002-06-18 Paul D. Smith <psmith@gnu.org>
3404 * make.texinfo: Updates for next revision. New date/rev/etc.
3405 Recreate all Info menus. Change license on the manual to the GNU
3406 Free Documentation License. A number of typos.
3407 (Variables Simplify): Don't use "-" before it's defined.
3408 (Automatic Prerequisites): Rewrite the target example to work
3409 properly if the compile fails. Remove incorrect comments about
3410 how "set -e" behaves.
3411 (Text Functions): Move the "word", "wordlist", "words", and
3412 "firstword" functions here, from "File Name Functions".
3413 * make-stds.texi: Update from latest GNU version.
3414 * fdl.texi: (created) Import the latest GNU version.
3416 2002-06-06 Paul D. Smith <psmith@gnu.org>
3418 * variable.c (do_variable_definition): New function: extract the
3419 part of try_variable_definition() that actually sets the value
3420 into a separate function.
3421 (try_variable_definition): Call do_variable_definition() after
3422 parsing the variable definition string.
3423 (define_variable_in_set): Make the name argument const.
3425 * variable.h (enum variable_flavor): Make public.
3426 (do_variable_definition): Create prototype.
3428 * read.c (read_all_makefiles): Create a new built-in variable,
3429 MAKEFILE_LIST.
3430 (read_makefile): Add each makefile read in to this variable value.
3432 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3434 * Makefile.DOS.template: Tweak according to changes in the
3435 distribution. Add back the dependencies of *.o files.
3437 * configh.dos.template: Synchronize with config.h.in.
3439 2002-05-09 Paul D. Smith <psmith@gnu.org>
3441 * file.c (file_timestamp_now): Use K&R function declaration.
3443 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3444 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3445 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3446 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3447 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3448 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3449 nlist.n_name is a pointer rather than an array.
3451 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3452 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3453 * configure.in: Use it instead of the old version.
3455 * main.c (main): Prefer setvbuf() to setlinebuf().
3457 2002-05-08 Paul D. Smith <psmith@gnu.org>
3459 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3460 (loadavg_LDADD): Ditto.
3462 2002-04-29 Paul D. Smith <psmith@gnu.org>
3464 * expand.c (recursively_expand_for_file): Rename
3465 recursively_expand() to recursively_expand_for_file() and provide
3466 an extra argument, struct file. If the argument is provided, set
3467 the variable scope to that of the file before expanding.
3468 * variable.h (recursively_expand): Make this a macro that invokes
3469 recursively_expand_for_file() with a NULL file pointer.
3470 * variable.c (target_environment): Call the renamed function and
3471 provide the current file context.
3472 Fixes Debian bug #144306.
3474 2002-04-28 Paul D. Smith <psmith@gnu.org>
3476 Allow $(call ...) user-defined variables to be self-referencing
3477 without throwing an error. Allows implementation of transitive
3478 closures, among other possibly useful things.
3479 Requested by: Philip Guenther <guenther@sendmail.com>
3481 * variable.h (struct variable): Add a new field: exp_count, and
3482 new macros to hold its size and maximum value.
3483 (warn_undefined): Make this a macro.
3484 * variable.c (define_variable_in_set): Initialize it.
3485 * expand.c (recursively_expand): If we detect recursive expansion
3486 of a variable, check the exp_count field. If it's greater than 0
3487 allow the recursion and decrement the count.
3488 (warn_undefined): Remove this (now a macro in variable.h).
3489 * function.c (func_call): Before we expand the user-defined
3490 function, modify its exp_count field to contain the maximum
3491 number of recursive calls we'll allow. After the call, reset it
3492 to 0.
3494 2002-04-21 Paul D. Smith <psmith@gnu.org>
3496 Modified to use latest autoconf (2.53), automake (1.6.1), and
3497 gettext (0.11.1). We're using gettext's new "external" support,
3498 to avoid including libintl source with GNU make.
3500 * README.cvs: New file. Explain how to build GNU make from CVS.
3502 * configure.in: Modify checking for the system glob library.
3503 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3504 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3505 etc. will manage it correctly). Set an automake conditional
3506 USE_LOCAL_GLOB to decide whether to compile the glob library.
3508 * getloadavg.c (main): Include make.h in the "TEST" program to
3509 avoid warnings.
3511 * Makefile.am: Remove special rules for loadavg. Replace them
3512 with Automake capabilities for building extra programs.
3514 * signame.c: This file does nothing if the system provide
3515 strsignal(). If not, it implements strsignal(). If the system
3516 doesn't define sys_siglist, then we make our own; otherwise we use
3517 the system version.
3518 * signame.h: Removed.
3520 * main.c (main): No need to invoke signame_init(). Update copyright.
3522 * ABOUT-NLS: Removed.
3523 * gettext.c: Removed.
3524 * gettext.h: Get a simplified copy from the gettext package.
3525 * po/*: Created.
3526 * i18n/*.po: Moved to po/.
3527 * i18n/: Removed.
3529 * config/*: Created. Contains package configuration helper files.
3530 * config.guess, config.sub: Moved to config directory.
3532 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3533 Rework to use new-style autoconf features. Use the "external"
3534 mode for gettext. Make the build.sh config file conditional on
3535 whether build.sh.in exists, to avoid autoconf errors.
3536 * acinclude.m4: Removed almost all macros as being obsolete.
3537 Rewrote remaining macros to use AC_DEFINE.
3538 * acconfig.h: Removed.
3540 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3541 conditional to handle customs support. Remove special handling
3542 for i18n features.
3544 2002-04-20 Paul D. Smith <psmith@gnu.org>
3546 * function.c (func_call): Don't mark the argument variables $1,
3547 etc. as recursive. They've already been fully expanded so
3548 there's no need to do it again, and doing so strips escaped $'s.
3549 Reported by Sebastian Glita <glseba@yahoo.com>.
3551 * remake.c (notice_finished_file): Walk through double-colon
3552 entries via the prev field, not the next field!
3553 Reported by Greg McGary <greg@mcgary.org>.
3555 * main.c (main): If the user specifies -q and asks for a specific
3556 target which is a makefile, we got an assert. In that case it
3557 turns out we should continue normally instead.
3559 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3561 * i18n/he.po: Installed a new translation.
3563 2002-01-07 Paul D. Smith <psmith@gnu.org>
3565 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3567 2001-12-04 Paul D. Smith <psmith@gnu.org>
3569 * i18n/ja.po: Installed an updated translation.
3571 2001-09-06 Paul Eggert <eggert@twinsun.com>
3573 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3574 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3576 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3577 are available.
3578 (main): Get rid of any avoidable limit on stack size.
3580 2001-09-04 Paul D. Smith <psmith@gnu.org>
3582 * i18n/da.po: Installed an updated translation.
3584 2001-08-03 Paul D. Smith <psmith@gnu.org>
3586 * i18n/fr.po: Installed an updated translation.
3587 Resolves Debian bug #106720.
3589 2001-06-13 Paul D. Smith <psmith@gnu.org>
3591 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3592 translation.
3594 2001-06-11 Paul D. Smith <psmith@gnu.org>
3596 * i18n/ko.po: Installed a new translation.
3598 2001-05-06 Paul D. Smith <psmith@gnu.org>
3600 Modify the EINTR handling.
3602 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3603 the way in which we manage the file descriptor/signal handler race
3604 trap to be more efficient.
3606 2001-05-06 Paul Eggert <eggert@twinsun.com>
3608 Restart almost all system calls that are interrupted, instead
3609 of worrying about EINTR. The lone exception is the read() for
3610 job tokens.
3612 * configure.in (HAVE_SA_RESTART): New macro.
3613 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3614 * main.c (main): Use SA_RESTART instead of the old,
3615 nonstandard SA_INTERRUPT.
3617 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3618 * main.c (bsd_signal): New function or macro,
3619 if the implementation doesn't supply it.
3620 (The bsd_signal function will be in POSIX 1003.1-200x.)
3621 (HANDLESIG): Remove.
3622 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3624 * make.h (EINTR_SET): Remove.
3625 (SA_RESTART): New macro.
3627 * arscan.c (ar_member_touch): Don't worry about EINTR.
3628 * function.c (func_shell): Likewise.
3629 * job.c (reap_children, free_child, new_job): Likewise.
3630 * main.c (main): Likewise.
3631 * remake.c (touch_file, name_mtime): Likewise.
3633 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3634 if fstat failed with errno!=EINTR, the error was ignored.
3636 * job.c (set_child_handler_action_flags): New function.
3637 (new_job): Use it to temporarily clear the SIGCHLD action flags
3638 while reading the token.
3640 2001-05-02 Paul D. Smith <psmith@gnu.org>
3642 * job.c (start_job_command): Don't add define/endef per-line flags
3643 to the top-level flags setting.
3645 2001-04-03 Paul D. Smith <psmith@gnu.org>
3647 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3648 bit on error, so check for odd return values, not non-0 return
3649 values.
3650 (VMS_get_member_info): Calculate the timezone differences correctly.
3651 Reported by John Fowler <jfowler@nyx.net>.
3654 2001-03-14 Paul D. Smith <psmith@gnu.org>
3656 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3657 value before invoking define_variable().
3658 Reported by John Fowler <jfowler@nyx.net>.
3660 2001-02-07 Paul D. Smith <psmith@gnu.org>
3662 * read.c (record_target_var): If we reset the variable due to a
3663 command-line variable setting overriding it, turn off the "append"
3664 flag.
3666 2001-01-17 Paul D. Smith <psmith@gnu.org>
3668 * variable.c (lookup_variable) [VMS]: When getting values from the
3669 environment, allocate enough space for the _value_ plus escapes,
3670 not enough space for the name plus escapes :-/.
3671 Reported by John Fowler <jfowler@nyx.net>.
3673 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3674 warnings that make generates, so it doesn't look like an error.
3675 Reported by Karl Berry <karl@gnu.org>.
3678 Fix for PR/2020: Rework appended target-specific variables. I'm
3679 fairly confident this algorithm is finally correct.
3681 * expand.c (allocated_variable_append): Rewrite. Instead of
3682 expanding each appended variable then adding all the expanded
3683 strings together, we append all the unexpanded values going up
3684 through the variable set contexts, then expand the final result.
3685 This behaves just like non-target-specific appended variable
3686 values, while the old way didn't in various corner cases.
3687 (variable_append): New function: recursively append the unexpanded
3688 value of a variable, walking from the outermost variable scope to
3689 the innermost.
3690 * variable.c (lookup_variable): Remove the code that looked up the
3691 variable set list if the found variable was "append". We don't
3692 need this anymore.
3693 (lookup_variable_in_set): Make this non-static so we can use it
3694 elsewhere.
3695 (try_variable_definition): Use lookup_variable_in_set() rather
3696 than faking out current_variable_set_list by hand (cleanup).
3697 * variable.h: Add a prototype for the now non-static
3698 lookup_variable_in_set().
3700 2000-11-17 Paul D. Smith <psmith@gnu.org>
3702 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3703 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3704 before throwing a fit.
3706 2000-11-17 Paul D. Smith <psmith@gnu.org>
3708 * read.c (readline): CRLF calculations had a hole, if you hit the
3709 buffer grow scenario just right. Reworked the algorithm to avoid
3710 the need for len or lastlen at all. Problem description with
3711 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3713 2000-10-24 Paul D. Smith <psmith@gnu.org>
3715 * gettext.c (SWAP): Declare this with the prototype, otherwise
3716 some systems don't work (non-32-bit? Reported for Cray T3E).
3717 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3719 2000-10-05 Paul D. Smith <psmith@gnu.org>
3721 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3722 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3724 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3726 2000-09-22 Paul D. Smith <psmith@gnu.org>
3728 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3729 parts of the real gettext.h here, and we expect to really include
3730 the real gettext.h later. If we keep this #define, it's ignored.
3732 2000-09-21 Paul D. Smith <psmith@gnu.org>
3734 * main.c (log_working_directory): Rework the text to use complete
3735 sentences, to make life simpler for the translators.
3737 2000-08-29 Paul D. Smith <psmith@gnu.org>
3739 * file.c (remove_intermediates): Print a debug message before we
3740 remove intermediate files, so the user (if she uses -d) knows
3741 what's going on.
3743 2000-08-21 Paul D. Smith <psmith@gnu.org>
3745 * variable.c (try_variable_definition): Change how we handle
3746 target-specific append variable defns: instead of just setting the
3747 value, expand it as an append _but_ only within the current
3748 target's context. Otherwise we lose all but the last value if the
3749 variable is appended more than once within the current target
3750 context. Fixes PR/1831.
3752 2000-08-16 Paul D. Smith <psmith@gnu.org>
3754 * function.c (func_shell): Nul-terminate the buffer before
3755 printing an exec error message (just in case it's not!).
3756 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3758 2000-07-25 Paul D. Smith <psmith@gnu.org>
3760 * job.c (construct_command_argv_internal): Add "~" to the list of
3761 sh_chars[] which disallow optimizing out the shell call.
3763 2000-07-23 Paul Eggert <eggert@twinsun.com>
3765 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3766 supersedes --disable-nsec-timestamps.
3767 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3768 * README: Remove --disable-nsec-timestamps.
3770 * filedef.h (struct file.low_resolution_time): New member.
3771 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3772 * remake.c (update_file_1):
3773 Avoid spurious rebuilds due to low resolution time stamps,
3774 generalizing the earlier code that applied only to archive members.
3775 (f_mtime): Archive members always have low resolution time stamps.
3777 * configure.in: Remove --disable-nsec-timestamps, as this has
3778 been superseded by .LOW_RESOLUTION_TIME.
3780 2000-07-23 Paul Eggert <eggert@twinsun.com>
3782 * configure.in (enable_nsec_timestamps): Renamed from
3783 make_cv_nsec_timestamps, since enable/disable options
3784 shouldn't be cached.
3786 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3787 and Paul Eggert <eggert@twinsun.com>
3789 * file.c (file_timestamp_now):
3790 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3791 so that clock_gettime is not linked unless needed.
3793 * filedef.h (FILE_TIMESTAMP_HI_RES):
3794 Remove definition; "configure" now does this.
3796 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3797 to before high resolution file timestamp check,
3798 since that check now uses uintmax_t.
3799 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3800 high resolution file timestamps.
3801 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3802 so that we don't link in clock_gettime unnecessarily.
3804 2000-07-17 Paul D. Smith <psmith@gnu.org>
3806 * i18n/ja.po: New version of the translation file.
3808 2000-07-07 Paul D. Smith <psmith@gnu.org>
3810 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3811 the offset calculation.
3812 (name_mtime): Replace EINTR test with EINTR_SET macro.
3814 2000-07-07 Paul Eggert <eggert@twinsun.com>
3816 Fix for PR/1811:
3818 * remake.c (update_file_1):
3819 Avoid spurious rebuilds of archive members due to their
3820 timestamp resolution being only one second.
3821 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3822 the clock's resolution being lower than file timestamps'.
3823 When warning about future timestamps, report only the discrepancy,
3824 not the absolute value of the timestamp and the current time.
3826 * file.c (file_timestamp_now): New arg RESOLUTION.
3827 * filedef.h (file_timestamp_now): Likewise.
3828 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3830 2000-07-05 Paul D. Smith <psmith@gnu.org>
3832 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3833 to listp. Fixes PR/1793.
3835 2000-06-26 Paul Eggert <eggert@twinsun.com>
3837 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3839 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3841 * remake.c (f_mtime): Remove unused var memtime.
3843 2000-06-25 Martin Buchholz <martin@xemacs.org>
3845 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3846 Ran spell-check on make.texinfo.
3848 2000-06-23 Paul D. Smith <psmith@gnu.org>
3850 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3851 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3852 * make.h: Define these macros.
3854 * Version 3.79.1 released.
3856 * configure.in: Add a new option, --disable-nsec-timestamps, to
3857 avoid using sub-second timestamps on systems that support it. It
3858 can lead to problems, e.g. if your makefile relies on "cp -p".
3859 * README.template: Document the issue with "cp -p".
3861 * config.guess, config.sub: Updated.
