52 which allows the caller to get the index of the matching directory.
54 * make.h (vpath_search): Update prototype.
56 * remake.c (library_search): Implement linker-compatible library
57 search. Use the new VPATH_SEARCH index functionality to keep track
58 of the directory index for each match. Select the match with the
59 lowest directory index.
61 * implicit.c (pattern_search): Pass NULL for the index arguments in
62 the VPATH_SEARCH call.
64 * doc/make.texi (Directory Search for Link Libraries): Describe the
65 new search behavior.
67 * NEWS: Add a note about the new behavior.
69 2009-10-25 Paul Smith <psmith@gnu.org>
71 * AUTHORS, et.al.: Update copyright years.
73 * implicit.c (stemlen_compare): Fix qsort() compare bug that
74 caused implicit rules with equal stem lengths to be sorted
75 indeterminately.
77 2009-10-24 Paul Smith <psmith@gnu.org>
79 * main.c (usage): Add --eval to the usage string.
80 (switches): Add the --eval switch.
81 (main): If --eval is given, add them to the simply-expanded variable
82 -*-eval-flags-*- (necessary to allow recursion to work properly).
83 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
85 * NEWS: Describe the new --eval command line argument.
86 * doc/make.texi (Options Summary): Document --eval.

114 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
115 to normal upgrade logic from dep_hash_cmp to set_file_variables.
117 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
119 * dep.h (uniquize_deps): Remove.
121 * read.c (uniquize_deps): Merge into set_file_variables in
122 commands.c.
123 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
125 * commands.c (set_file_variables): Avoid modifying the dep
126 chain to achieve uniqueness. Fixes savannah bug 25780.
128 * implicit.c (pattern_search): Instead of re-setting all automatic
129 variables for each rule we try, just update $*.
131 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
133 * variable.h (undefine_variable_in_set): New function declaration.
134 (undefine_variable_global): New macro.

149 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
151 * implicit.c (pattern_search): Initialize file variables only
152 if we need to parse a rule that requires the second expansion.
154 2009-10-03 Paul Smith <psmith@gnu.org>
156 * make.h: Include <alloca.h> even on systems where __GNUC__ is
157 defined. Not sure why it was done the other way.
158 Requested by David Boyce <dsb@boyski.com>.
160 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
162 * dep.h (dep): Add the DONTCARE bitfield.
164 * filedef.h (file):Add the NO_DIAG bitfield.
166 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
167 not struct file (a file can be a dependency of many targets,
168 some don't care, some do).
170 * remake.c (update_goal_chain): Propagate DONTCARE from struct
171 dep to struct file before updating the goal and restore it
172 afterwards.
173 (update_file): Don't prune the dependency graph if this target
174 has failed but the diagnostics hasn't been issued.
175 (complain): Scan the file's dependency graph to find the file
176 that caused the failure.
177 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
178 whether to print diagnostics.
180 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
182 2009-09-28 Paul Smith <psmith@gnu.org>
184 * doc/make.texi (Pattern Intro): Move the match algorithm
185 discussion into the "Pattern Match" node.

188 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
190 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
191 much of the command line on a single pass.
193 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
195 * varible.c (create_pattern_var): Insert variables into the
196 PATTERN_VARS list in the shortest patterns first order.
198 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
199 used to sort the rules.

201 (pattern_search): Sort the rules so that they are in the shortest
202 stem first order.

216 double-colons have a different meaning. Savannah bug #27497.
218 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
220 * configh.dos.template: Remove unconditional definition of
221 SYS_SIGLIST_DECLARED.
222 Include <sys/version.h> because ports of GCC 4.3.0 and later no
223 longer include it, so macros like __DJGPP_MINOR__ are no longer
224 defined automatically.
226 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
227 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
228 instead of using the hardcoded ones.
229 (SUBDIRS): doc subdir added.
230 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
231 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
232 create html formated docs. texi2html may not be ported to DOS.
233 (make.info, make.dvi, make.ps, make.html): Make targets depend on
234 'make.texi'.
235 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
236 -I switch to look in ./ instead of ./doc.
237 (html): Target depend on html-recursive instead of make_1.html.
238 (make_1.html): Removed.
239 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
240 (all-recursive): Allow for more than one subdir in the build
241 process.
242 (mostlyclean-recursive, clean-recursive, distclean-recursive)
243 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
244 (tags-recursive): Allow for more than one subdir in the build
245 process.
246 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
247 targets. Enter into doc/ to produce the targets.
248 (all-am): $(INFO_DEPS) replaced by info.
250 2009-09-26 Paul Smith <psmith@gnu.org>
252 * read.c (record_files): Use free_ns() to free struct nameseq.
253 (eval): Ditto.
255 * rule.c (freerule): Use free_dep_chain().
257 * read.c (record_files): Free FILENAMES chain for implicit rules.
258 (eval): Static pattern targets go into the string cache.
260 * function.c (string_glob): Free NAME in the nameseq chain.
262 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
264 * implicit.c (pattern_search): Terminate early if we haven't
265 found any rules to try (performance improvement).
267 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
269 * implicit.c (pattern_search): Merge three parallel arrays,
270 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
271 of struct TRYRULE. In the old version the latter two arrays
272 had insufficient length.
274 2009-09-24 Paul Smith <psmith@gnu.org>
276 * implicit.c (pattern_search): Add back support for order-only
277 prerequisites for secondary expansion implicit rules, that were
278 accidentally dropped. If we find a "|", enable order-only mode
279 and set IGNORE_MTIME on all deps that are seen afterward.
280 (pattern_search): Fix memory leaks: for intermediate files where
281 we've already set the file variable and pattern variable sets, be
282 sure to either save or free them as appropriate.
284 2009-09-23 Paul Smith <psmith@gnu.org>
286 Rework the way secondary expansion is stored, for efficiency.
287 This changes secondary expansion so that ONLY WHEN we know we have
288 a possibility of needing secondary expansion, do we defer the
289 secondary expansion. This means more parsing the deps but we use
290 a lot less memory (due to the strcache). Also, this fixes
291 Savannah bug #18622.
293 * read.c (eval): Don't parse the dep string here anymore.
294 (record_files): Take the dep argument as an unparsed string. If
295 secondary expansion is enabled AND the prereq string has a '$' in
296 it, then set NEED_2ND_EXPANSION and keep the entire string.
297 Otherwise, parse the dep string here to construct the dep list
298 with the names in the strcache.
300 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
301 duplicate the name string (others are in the strcache).
303 * implicit.c: Remove struct idep and free_idep_chain(): unused.
304 (struct patdeps): New structure to store prereq information.
305 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
306 which prerequisites need expansion, and expand only those.
308 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
309 and enter_prereqs(). split_prereqs() takes a fully-expanded string
310 and splits it into a DEP list, handling order-only prereqs.
311 (enter_prereqs): This function enters a list of DEPs into the file
312 database. If there's a stem defined, expand any pattern chars.
313 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
314 set. Use the above functions.
315 (snap_deps): Only perform second expansion on prereqs that need it,
316 as defined by the NEED_2ND_EXPANSION flag.
317 (print_prereqs): New function to print the prereqs
318 (print_file): Call print_prereqs() rather than print inline.
320 * hash.h (STRING_COMPARE): Take advantage of strcache() by
321 comparing pointers.
322 (STRING_N_COMPARE): Ditto.
323 (ISTRING_COMPARE): Ditto.
325 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
326 (parse_file_seq): Return void*
327 * read.c (parse_file_seq): Return void*.
328 (eval): Invoke macroized version of parse_file_seq()
329 * default.c (set_default_suffixes): Ditto.
330 * file.c (split_prereqs): Ditto.
331 * function.c (string_glob): Ditto.
332 * main.c (main): Ditto.
333 * rule.c (install_pattern_rule): Ditto.
335 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
337 2009-09-16 Paul Smith <psmith@gnu.org>
339 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
340 convert to macros.
341 * dep.h: Create alloc_dep() / free_dep() macros.
343 * implicit.c (pattern_search): Take advantage of the new
344 parse_file_seq() to add the directory prefix to each prereq.
346 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
347 all. Avoid reversing chains. Support adding prefixes.
348 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
349 cached/non-cached results.
350 (eval): Remove multi_glob() & invoke new parse_file_seq().
351 * rule.c (install_pattern_rule): Ditto.
352 * main.c (main): Ditto.
353 * implicit.c (pattern_search): Ditto.
354 * function.c (string_glob): Ditto.
355 * file.c (parse_prereqs): Ditto.
356 * default.c (set_default_suffixes): Ditto.
358 * variable.c (parse_variable_definition): Don't run off the end of
359 the string if it ends in whitespace (found with valgrind).
361 * commands.c (set_file_variables): Keep space for all targets in
362 $? if -B is given (found with valgrind).
364 2009-09-15 Paul Smith <psmith@gnu.org>
366 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
367 (xcalloc): Add new function.
368 * make.h: New declarations.
370 * ar.c (ar_glob_match): New calling method for concat().
371 * main.c (main): Ditto.
372 (decode_env_switches): Ditto.
373 * read.c (eval_makefile): Ditto.
374 (tilde_expand): Ditto.
375 (parse_file_seq): Ditto.
376 * variable.c (target_environment): Ditto.
377 (sync_Path_environment): Ditto.
379 * ar.c (ar_glob_match): Use xcalloc().
380 * dir.c (file_impossible): Ditto.
381 * file.c (enter_file): Ditto.
382 * job.c (new_job): Ditto.
383 * read.c (parse_file_seq): Ditto.
384 * vmsfunctions.c (opendir): Ditto.
386 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
388 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
389 inside the loop that looks up environment for PATH.
391 2009-08-31 Eli Zaretskii <eliz@gnu.org>
393 * function.c (windows32_openpipe): Update envp after calling
394 sync_Path_environment.
396 2009-08-02 Paul Smith <psmith@gnu.org>
398 * remake.c (notice_finished_file): Ensure file->cmds is not null
399 before looping through them. Fixes Savannah bug #21824.
401 * doc/make.texi (Wildcard Examples): Clarify when objects is
402 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
403 (Include): Clarify the behavior of -include.
404 Fixes Savannah bug #18963.
406 2009-08-01 Paul Smith <psmith@gnu.org>
408 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
409 etc. come on the command line. Fixes Savannah bug #27093.
411 * expand.c (expand_argument): If the argument is large enough use
412 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
414 * variable.c (do_variable_definition): Avoid using alloca() to
415 hold values, which can be large. Fixes Savannah bug #23960.
417 * job.c (new_job): Use memmove() instead of strcpy() since both
418 pointers are in the same memory block. Fixes Savannah bug #27148.
419 Patch by Petr Machata.
421 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
423 * job.c (construct_command_argv_internal): Add "ulimit" and
424 "unset" to the sh_cmds for Unixy shells.
426 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
428 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
429 that set make_cv_sys_gnu_glob, so they are also correctly set
430 when the cache has been populated before.
432 2009-07-04 Eli Zaretskii <eliz@gnu.org>
434 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
435 exist, as realpath(3) does where it's supported.
437 2006-07-04 Eli Zaretskii <eliz@gnu.org>
439 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
440 (abspath): Support systems that define HAVE_DOS_PATHS (have
441 drive letters in their file names). Use IS_PATHSEP instead of a
442 literal '/' comparison. Fixes Savannah bug #26886.
444 2009-06-14 Paul Smith <psmith@gnu.org>
446 * remake.c (update_file_1): Remember the original file we marked
447 as updating, so we can clear that flag again. If we find a target
448 via vpath, FILE might change.
449 (check_dep): Ditto. Fixes Savannah bug #13529.
450 Patch by Reid Madsen <reid.madsen@tek.com>.
452 2009-06-13 Paul Smith <psmith@gnu.org>
454 * doc/make.texi (MAKEFILES Variable): Be explicit that files
455 included by MAKEFILES cannot give default goals.
456 * read.c (eval): If set_default is not set, pass the no-default-goal
457 value when we read included makefiles. Fixes Savannah bug #13401.
459 * ar.c (ar_name): Ensure that targets with empty parens aren't
460 considered archive member references: archive members must have a
461 non-empty "member" string. Fixes Savannah bug #18435.
463 * function.c (string_glob): Rely on multi_glob() to determine
464 whether files exist or not. Remove call to file_exists_p() which
465 is not always correct. Fixes Savannah bug #21231.
466 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
467 then only files that really exist will be returned.
468 * dep.h: Add new argument to multi_glob().
469 * rule.c (install_pattern_rule): Ditto.
470 * read.c (eval): Ditto.
471 * main.c (main): Ditto.
472 * implicit.c (pattern_search): Ditto.
473 * file.c (parse_prereqs): Ditto.
474 * default.c (set_default_suffixes): Ditto.
476 2009-06-09 Paul Smith <psmith@gnu.org>
478 * commands.c (set_file_variables): If always_make_flag is set,
479 always add the prereq to $?. Fixes Savannah bug #17825.
481 * remake.c (update_file_1): When rebuilding deps of FILE, also try
482 to rebuild the deps of all the also_make targets for that file.
483 Fixes Savannah bug #19108.
485 * implicit.c (pattern_search): Undo test for is_target, added by
486 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
487 Rule Search Algorithm". Fixes Savannah bug #17752.
489 * main.c (clean_jobserver): Clear the jobserver_fds options and
490 set job_slots to the default when we clean up.
491 (define_makeflags): Return the new MAKEFLAGS value.
492 (main): Reset MAKEFLAGS in the environment when we re-exec.
493 Fixes Savannah bug #18124.
495 2009-06-08 Paul Smith <psmith@gnu.org>
497 * read.c (eval): Collapse continuations post-semicolon on target-
498 specific variables. Fixes Savannah bug #17521.
500 2009-06-07 Paul Smith <psmith@gnu.org>
502 * job.c (reap_children): For older systems without waitpid() (are
503 there any of these left?) run wait(2) inside EINTRLOOP to handle
504 EINTR errors. Fixes Savannah bug #16401.
506 * (various): Debug message cleanup. Fixes Savannah bug #16469.
508 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
510 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
511 not the end, to catch second expansion $(eval ...) defining new
512 target/prereq relationships during snap_deps.
513 Fixes Savannah bug #24622.
515 * read.c (record_files): The second-expansion "f->updating" hack
516 was not completely correct: if assumed that the target with
517 commands always had prerequisites; if one didn't then the ordering
518 was messed up. Fixed for now to use f->updating to decide whether
519 to preserve the last element in the deps list... but this whole
520 area of constructing and reversing the deps list is too confusing
521 and needs to be reworked. Fixes Savannah bug #21198.
523 2009-06-06 Paul Smith <psmith@gnu.org>
525 * hash.c (hash_insert): Remove useless test for NULL.
526 Fixes Savannah bug #21823.
528 * make.h: Move SET_STACK_SIZE determination to make.h.
529 * main.c (main): New global variable, STACK_LIMIT, holds the
530 original stack limit when make was started.
531 * job.c (start_job_command): Reset the stack limit, if we changed it.
532 Fixes Savannah bug #22010.
534 * remake.c (check_dep): Only set the target's state to not-started
535 if it's not already running. Found this while testing -j10 builds
536 of glibc: various targets were being rebuilt multiple times.
537 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
538 bug #15919.
540 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
541 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
542 Bugzilla bug 10246.
544 2009-06-04 Paul Smith <psmith@gnu.org>
546 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
548 * maintMakefile: Modify access of config and gnulib Savannah
549 modules to use GIT instead of CVS.
551 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
552 Fixes Savannah bug #24655.
554 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
555 this can happen during some invocations of $(eval ...) for example.
556 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
558 2009-06-02 Paul Smith <psmith@gnu.org>
560 * configure.in: Check for fileno()
561 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
562 for the makefile file so invocations of $(shell ...) don't inherit it.
563 Fixes Savannah bug #24277.
565 2009-06-01 Paul Smith <psmith@gnu.org>
567 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
568 expansion was handled incorrectly. Rework the default goal
569 handling to save the variable only. Remove default_goal_file and
570 default_goal_name.
571 * read.c (eval): Check default_goal_var, not default_goal_name.
572 * read.c (record_target_var): Don't check default_goal_file here.
574 2009-05-31 Paul Smith <psmith@gnu.org>
576 * main.c (main): Expand the .DEFAULT_GOAL variable before using
577 it, and if the multi_glob() returns nothing (say it expanded to
578 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
580 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
581 $(and ..) to the reference. Fixes Savannah bug #25694.
583 * make.1: Be clear that some recipes will be executed even with -n.
584 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
586 * doc/make.texi (Override Directive): Make more clear how
587 overrides and appends interact.
588 Elucidates part of Savannah bug #26207.
590 * read.c (record_target_var): Don't reset the origin on
591 target-specific variables; try_variable_definition() will handle
592 this correctly. Fixes Savannah bug #26207.
594 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
595 Fixes Savannah bug #25712.
597 * implicit.c (pattern_search): Keep a pointer to the beginning of
598 the filename and save that instead of the constructed pointer.
599 Fixes Savannah bug #26593.
600 Patch by Mark Seaborn <mrs@mythic-beasts.com>
602 2009-05-30 Paul Smith <psmith@gnu.org>
604 * doc/make.texi (Multi-Line): Add a description of the new abilities
605 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
606 "command sequence" vs. "recipe" syntax.
607 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
608 after a define, to create variables with those flavors.
610 2009-05-25 Paul Smith <psmith@gnu.org>
612 Reworked the parser for variable assignments to allow multiple
613 modifiers, and in any order. Also allows variable and
614 prerequisites to be modifier names ('export', 'private', etc.)
616 * NEWS: Add notes about user-visible changes.
618 * read.c (struct vmodifiers): Remember what modifiers were seen.
619 (parse_var_assignment): New function to parse variable assignments.
620 (eval): Call the new function. Handle variable assignments earlier.
622 * variable.c (parse_variable_definition): Only parse; don't create var.
623 (assign_variable_definition): Call parse, then create the var.
625 2009-05-24 Paul Smith <psmith@gnu.org>
627 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
628 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
630 2009-03-14 Eli Zaretskii <eliz@gnu.org>
632 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
633 Fixes Savannah bug #25412.
635 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
636 prototype for xmalloc.
637 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
638 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
639 Loop over an array of extensions, instead of duplicating the same
640 code inline. Use SearchPath followed by CreateFile, instead of
641 the obsolete OpenFile. Fixes Savannah bug #17277.
642 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
643 to `find_file'. Fixes Savannah bug #25662.
645 2009-03-07 Eli Zaretskii <eliz@gnu.org>
647 * function.c (func_shell): Don't close pipedes[1] if it is -1.
648 Fixes Savannah bug #20495.
650 2009-02-28 Ralf Wildenhues <address@hidden>
652 * doc/make.texi (Instead of Execution): Document interaction of
653 -t with phony targets.
655 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
657 Introduce a new keyword "private" which applies to target-specific
658 variables and prevents their values from being inherited.

674 if it's available.
675 * make.h: Rename savestring to xstrndup.
676 * commands.c (chop_commands): Ditto.
677 * function.c (func_foreach): Ditto.

681 2008-09-30 Eli Zaretskii <eliz@gnu.org>
683 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
684 "-gstabs+ -ggdb3".
686 * w32/subproc/build.bat (GCCBuild): Likewise.
688 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
690 * job.c (construct_command_argv_internal): Avoid extra backslash
691 in batch-mode Unixy shells. Under DB_JOBS, display the contents
692 of the batch file.
694 2008-05-31 Eli Zaretskii <eliz@gnu.org>
696 * README.W32.template: Remove obsolete text about non-support for
697 -jN without Unixy shell. Remove obsolete text about not supplying
698 Visual Studio project files (we do supply them). Modify text to
699 prefer GCC builds to MSC builds.
701 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
703 * doc/make.texi (Empty Targets): Fix typo.

713 * maintMakefile: Update Translation Project location.
715 2008-01-26 Eli Zaretskii <eliz@gnu.org>
717 * variable.c (target_environment): Don't use shell_var if its
718 `value' field is NULL.
720 2007-12-22 Eli Zaretskii <eliz@gnu.org>
722 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
724 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
725 (TEXINFOS): Value changed to `doc/make.texi'.
726 (.SUFFIXES): Use .texi instead of .texinfo.
727 (make.info, make.dvi): Depend on doc/make.texi.
728 (.texi.info): New target, instead of ".texinfo.info". Change -I
729 switch to $(MAKEINFO) to look in doc/. Use --no-split.
730 (.texi): New target, instead of ".texinfo". Change -I switch to
731 $(MAKEINFO) to look in doc/. Use --no-split.
732 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
733 switch to $(MAKEINFO) to look in doc/.
734 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
735 "*.i[0-9][0-9]" (due to --no-split above).
736 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
737 (html, make_1.html): New targets.
738 (.PHONY): Add "html".
739 (.SUFFIXES): Add .html.
741 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
743 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
744 HAVE_DECL_SYS_SIGLIST.
746 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
747 build does not use child_execute_job.
749 * variable.c (define_automatic_variables) [__MSDOS__]: Always
750 export the SHELL environment variable to the child.
752 2007-12-22 Eli Zaretskii <eliz@gnu.org>
754 * config.h.W32: Include sys/types.h.
755 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
757 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
758 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
759 also `:'.
761 2007-11-04 Paul Smith <psmith@gnu.org>
763 * doc/make.texi: Convert references to "commands", "command
764 lines", and "command script" to "recipe".
765 * NEWS: Ditto.
766 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
767 Ditto.
769 2007-10-27 Bruno Haible <bruno@clisp.org>
771 * remake.c (f_mtime): Print time difference values between 100 and
772 ULONG_MAX in fixed-point notation rather than in exponention notation.
774 2007-10-12 Eli Zaretskii <eliz@gnu.org>
776 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
777 a more complex value than a simple shell: if it's not a default
778 shell now then expand it and see if is a default shell then.
780 2007-10-10 Eli Zaretskii <eliz@gnu.org>
782 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
783 pathnames, with const strings.
784 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
785 from the template (used for building from CVS, not a dist).
787 2007-10-10 Paul Smith <psmith@gnu.org>
789 * make.h: Add a prototype for w32_kill() (change suggested by
790 Yongwei Wu <wuyongwei@gmail.com>).
792 2007-09-21 Eli Zaretskii <eliz@gnu.org>
794 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted

802 Provided by Diego Biurrun <diego@biurrun.de>
804 2007-09-11 Paul Smith <psmith@gnu.org>
806 * doc/make.texi (Special Variables): Moved this into the "How to
807 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
808 (MAKEFILE_LIST) No longer a section; this was added into the
809 "Special Variables" section.
810 (Rule Introduction): Reference .RECIPEPREFIX.
811 (Simple Makefile): Ditto.
812 (Rule Syntax): Ditto.
813 (Command Syntax): Ditto.
814 (Error Messages): Ditto.
816 2007-09-10 Paul Smith <psmith@gnu.org>
818 * commands.c (print_commands): Don't print an extra line in the
819 command scripts. Prefix the command scripts with cmd_prefix, not \t.
821 * read.c (construct_include_path): Add the full string to the cache; we
822 were chopping the last char.
824 * NEWS: Announce the .RECIPEPREFIX special variable.
825 * variable.c (lookup_special_var): Rename from handle_special_var().
826 (lookup_variable): Call the new name.
827 (set_special_var): New function: handle setting of special variables.
828 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
829 (do_variable_definition): Call it.
830 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
831 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
832 * main.c (main): Create the .RECIPEPREFIX special variable.
833 * read.c (eval): Remove the cmd_prefix characters from the command
834 scripts here, so they're not stored in the commands array at all,
835 rather than waiting and stripping them out during command construction.
836 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
838 2007-08-15 Paul Smith <psmith@gnu.org>
840 * doc/make.texi (GNU Free Documentation License): The fdl.texi
841 file has had the section info removed, so add some to make.texi
842 before we include it.
844 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
846 * remake.c (check_dep): Reset the target state for intermediate
847 files. They might have been considered before but not updated
848 then (order-only for example) but they will be this time.
849 Fixes Savannah bug #'s 3330 and 15919.
851 2007-07-21 Eli Zaretskii <eliz@gnu.org>

854 * function.c (func_shell): Call construct_command_argv with zero
855 value of FLAGS.
856 * job.c (construct_command_argv_internal): New argument FLAGS; all
857 callers changed.
858 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
859 just_print_flag.
860 * job.h (construct_command_argv_internal): Update prototype.
862 2007-07-13 Paul Smith <psmith@gnu.org>
864 * file.c (expand_deps): Use variable_buffer as the start of the
865 buffer, not the original pointer (in case it was reallocated).
866 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
867 Fixes Savannah bug #20452.
869 2007-07-04 Paul Smith <psmith@gnu.org>
871 * (ALL FILES): Update to GPLv3.
872 * (ALL FILES): Update copyright for 2007.

876 2007-06-29 Thiemo Seufer <ths@mips.com>
878 * maintMakefile: Update Translation Project location.
880 2007-06-13 Paul Smith <psmith@gnu.org>
882 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
883 "Expansion of a deferred"
884 Fixes Savannah bug #20018.

888 Fixes Savannah bug #20033.
890 2007-05-11 Paul Smith <psmith@gnu.org>
892 * job.c (new_job): Add debug info to specify where make found the
893 command script it is running to build a target.
894 Fixes Savannah bug #18617.
896 * default.c (default_suffixes,default_suffix_rules,default_variables):
897 Add support for Objective C. Fixes Savannah bug #16389.
898 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
900 * function.c (func_lastword): Initialize p.
902 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
903 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
904 Dave Korn <dave.korn@artimi.com>
906 2007-05-08 Paul Smith <psmith@gnu.org>
908 Fix Savannah bug #19656:
910 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
912 * make.h: Change all case-insensitive string compares to use
913 strcasecmp() (from POSIX). If we don't have that but do have one
914 of the others, define strcasecmp to be one of those instead. If
915 we don't have any, declare a prototype for our own version.
917 * misc.c (strcasecmp): Use this if we can't find any native
918 case-insensitive string comparison function.
919 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
920 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
921 strcmpi().
922 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
923 strcasecmp() instead of stricmp().
924 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
925 instead of strcmpi().
926 * acinclude.m4: Remove the strcasecmp() check from here.
928 2007-03-21 Paul Smith <psmith@gnu.org>
930 * configure.in: Don't turn on case-insensitive file system support
931 if --disable-... is given. Fixes Savannah bug #19348.
933 2007-03-19 Paul Smith <psmith@gnu.org>
935 * ALL: Use the strcache for all file name strings, or other
936 strings which we will never free. The goal is to save memory by
937 avoiding duplicate copies of strings. However, at the moment this
938 doesn't save much memory in most situations: due to secondary
939 expansion we actually save prerequisite lists twice (once before
940 the secondary expansion, and then again after it's been parsed
941 into individual file names in the dep list). We will resolve this
942 in a future change, by doing the parsing up-front for targets
943 where secondary expansion is not set.
945 Moving things into the strcache also allows us to use const
946 pointers in many more places.
948 2007-01-03 Paul Smith <psmith@gnu.org>
950 * make.h (ENULLLOOP): Reset errno after each failed invocation of
951 the function, not just the first. Fixes Savannah bug #18680.
953 2006-11-18 Paul Smith <psmith@gnu.org>
955 * strcache.c (strcache_add_len): Don't allocate a new buffer
956 unless the string is not already nil-terminated. Technically this
957 is a violation of the standard, since we may be passed an array
958 that is not long enough to test one past. However, in make this
959 is never true since we only use nil-terminated strings or
960 sub-strings thereof.
962 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
964 * main.c: New global cmd_prefix, defaults to '\t'.
965 * job.c (construct_command_argv_internal): Use cmd_prefix instead
966 of '\t'.
968 * dir.c: Constified.
969 (dir_contents_file_exists_p): Check for an error return from
970 readdir(), just in case.
972 * commands.c: Constified.
973 * default.c: Constified.
974 * expand.c: Constified.
975 * function.c: Partial constification.
976 * variable.c: Partial constification.
977 * vmsify.c: Constification. Hard to test this but I hope I didn't
978 screw it up!
979 * vpath.c: Partial constification.
980 * w32/pathstuff.c: Partial constification.
982 2006-11-16 Eli Zaretskii <eliz@gnu.org>
984 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
985 backslashes and drive letters as absolute.
987 2006-10-22 Paul Smith <psmith@gnu.org>
989 * main.c (struct command_switch): Use const and void*.
991 2006-10-21 Paul Smith <psmith@gnu.org>
993 * ar.c: Constified.
994 * arscan.c: Constified.
996 2006-09-30 Paul Smith <psmith@gnu.org>
998 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
999 point to lastword since the example was updated.
1000 Fixes Savannah bug #16304.
1001 (Secondary Expansion): Correct example description.
1002 Fixes Savannah bug #16468.
1003 (Makefile Contents): Clarify that comments cannot appear within
1004 variable references or function calls.
1005 Fixes Savannah bug #16577.
1006 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1007 Fixes Savannah bug #17701.
1008 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1009 (Prerequisite Types): Added an example of using order-only
1010 prerequisites. Fixes Savannah bug #17880.
1011 (Rule Syntax): "lise" -> "list"
1012 (Multiple Rules): ... -> @dots{}
1013 (Splitting Lines): ditto.
1015 * remake.c (update_file_1): Prereqs that don't exist should be
1016 considered changed, for the purposes of $?.
1017 Fixes Savannah bug #16051.
1019 * make.1: Remove extraneous "+".
1020 Fixes Savannah bug #16652.
1022 2006-09-06 Paul D. Smith <psmith@gnu.org>
1024 * configure.in: Include sys/types.h when checking for sys/wait.h.

1028 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1029 $PATH_SEPARATOR.
1031 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1032 Normally, it is defined in config.h.
1034 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1035 well.
1037 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1038 sh_chars_sh for Windows platforms that emulate Unix.
1040 2006-05-07 Paul D. Smith <psmith@gnu.org>
1042 * README.OS2.template: Updates provided by Andreas Buening
1043 <andreas.buening@nexgo.de>.
1045 2006-04-30 Paul D. Smith <psmith@gnu.org>
1047 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1048 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.

1056 2006-04-20 Paul D. Smith <psmith@gnu.org>
1058 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1059 that don't have extended grep.
1060 (cvsclean): Use $(PERL) instead of perl.
1062 2006-04-09 Paul D. Smith <psmith@gnu.org>
1064 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1066 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1067 inner-scope variables don't mask outer-scope variables.
1069 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1070 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1071 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1072 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1073 values from memory allocation functions: they return void* and so
1074 don't need to be cast. Also remove (char *) casts of arguments to
1075 xrealloc().
1077 * configure.in: Remove checks for memcpy/memmove/strchr.
1079 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1081 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp
1082 calls to memset/memcpy/memmove/memcmp calls.
1083 * expand.c, file.c, function.c, getloadavg.c, implicit.c: Ditto.

1089 2006-04-06 Paul D. Smith <psmith@gnu.org>
1091 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1092 require an ISO C 1989 standard compiler and runtime library.
1094 * Makefile.am: Remove the ansi2knr feature.
1096 * make.h: Remove the PARAMS() macro definition and all uses of it.
1098 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
1099 * commands.c, commands.h, config.h-vms.template: Ditto.
1100 * dep.h, dir.c, expand.c, filedef.h, function.c: Ditto.
1101 * implicit.c, job.c, job.h, main.c, read.c, remake.c: Ditto.
1102 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
1104 * NEWS: Update.
1106 2006-04-01 Paul D. Smith <psmith@gnu.org>
1108 Version 3.81 released.
1110 * NEWS: Updated for 3.81.
1112 * README.cvs: Mention that vpath builds are not supported out of
1113 CVS. Fixes Savannah bug #16236.
1114 Remove update of make.texi from the list of things to do; we use
1115 version.texi now.
1117 2006-03-26 Paul D. Smith <psmith@gnu.org>
1119 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1120 support from automake, as described in the Texinfo manual.
1122 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1124 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1125 with lastslash, since the latter points to filename, not to
1126 target.
1127 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1128 Declare and define sh_chars_sh[].
1130 2006-03-23 Paul D. Smith <psmith@gnu.org>
1132 * configure.in: Look for build.sh.in in $srcdir so it will be
1133 built for remote configurations as well.
1135 * Makefile.am: Make sure to clean up build.sh during distclean.
1136 Fixes Savannah bug #16166.
1138 * misc.c (log_access): Takes a const char *.
1139 * function.c (fold_newlines): Takes an unsigned int *.
1140 Both fixes for Savannah bug #16170.
1142 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1144 * implicit.c (pattern_search): Call set_file_variables only
1145 if we have prerequisites that need second expansion. Fixes
1146 Savannah bug #16140.
1148 2006-03-19 Paul D. Smith <psmith@gnu.org>
1150 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1151 memory on hosts that don't support it directly.
1153 * README.cvs: Add information on steps for making a release (to
1154 make sure I don't forget any).
1156 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1157 function.
1158 (die): Cleanup code was removed from here; call the new function.
1159 (main): If we are re-execing, clean up the jobserver first so we
1160 don't leak file descriptors.
1161 Reported by Craig Fithian <craig.fithian@citigroup.com>
1163 2006-03-17 Paul D. Smith <psmith@gnu.org>
1165 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1166 allow multiple concurrent runs.
1167 Patch from Joseph Myers <joseph@codesourcery.com>
1169 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1171 * dep.h (struct dep): Add the stem field.
1172 * misc.c (alloc_dep, free_dep): New functions.
1173 (copy_dep_chain): Copy stem.
1174 (free_dep_chain): Use free_dep.
1175 * read.c (record_files): Store stem in the dependency line.
1176 * file.c (expand_deps): Use stem stored in the dependency line. Use
1177 free_dep_chain instead of free_ns_chain.
1178 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1179 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1180 * main.c (main, handle_non_switch_argument): Ditto.
1181 * remake.c (check_dep): Ditto.
1182 * rule.c (convert_suffix_rule, freerule): Ditto.
1184 2006-03-14 Paul D. Smith <psmith@gnu.org>
1186 * expand.c (variable_append): Instead of appending everything then
1187 expanding the result, we expand (or not, if it's simple) each part
1188 as we add it.
1189 (allocated_variable_append): Don't expand the final result.
1190 Fixes Savannah bug #15913.
1192 2006-03-09 Paul Smith <psmith@gnu.org>
1194 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1195 listed non-existent files as changed. Turns out there's a bug in
1196 the Linux kernel builds which means that this change causes
1197 everything to rebuild every time. We will re-introduce this fix
1198 in the next release, to give them time to fix their build system.
1199 Fixes Savannah bug #16002.
1200 Introduces Savannah bug #16051.
1202 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1203 we *don't* find UNIX "/".
1204 Reported by David Ergo <david.ergo@alterface.com>
1206 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1208 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1209 locator function find_and_set_default_shell if SHELL came from the
1210 command line.
1212 2006-02-20 Paul D. Smith <psmith@gnu.org>
1214 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1215 to be null; don't core in that case.
1217 2006-02-19 Paul D. Smith <psmith@gnu.org>
1219 * commands.c (set_file_variables): Realloc, not malloc, the static
1220 string values to avoid memory leaks.
1222 * expand.c (recursively_expand_for_file): Only set reading_file to
1223 an initialized value.
1225 * implicit.c (pattern_search): We need to make a copy of the stem
1226 if we get it from an intermediate dep, since those get freed.
1228 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1229 begin with ".".
1230 (enter_file) [VMS]: Ditto.
1231 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1233 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1235 * job.c (construct_command_argv_internal): Fix last change.
1237 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1238 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1239 the calls to _beginthreadex.
1241 * expand.c (recursively_expand_for_file): Initialize `save' to
1242 prevent compiler warnings.
1244 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1246 * job.c (construct_command_argv_internal): Don't create a temporary
1247 script/batch file if we are under -n. Call _setmode to switch the
1248 script file stream to text mode.
1250 2006-02-17 Paul D. Smith <psmith@gnu.org>
1252 * variable.c (merge_variable_set_lists): Don't try to merge the
1253 global_setlist. Not only is this useless, but it can lead to
1254 circularities in the linked list, if global_setlist->next in one
1255 list gets set to point to another list which also ends in
1256 global_setlist.
1257 Fixes Savannah bug #15757.
1259 2006-02-15 Paul D. Smith <psmith@gnu.org>
1261 Fix for Savannah bug #106.
1263 * expand.c (expanding_var): Keep track of which variable we're
1264 expanding. If no variable is being expanded, it's the same as
1265 reading_file.
1266 * make.h (expanding_var): Declare it.
1267 * expand.c (recursively_expand_for_file): Set expanding_var to the
1268 current variable we're expanding, unless there's no file info in
1269 it (could happen if it comes from the command line or a default
1270 variable). Restore it before we exit.
1271 * expand.c (variable_expand_string): Use the expanding_var file
1272 info instead of the reading_file info.
1273 * function.c (check_numeric): Ditto.
1274 (func_word): Ditto.
1275 (func_wordlist): Ditto.
1276 (func_error): Ditto.
1277 (expand_builtin_function): Ditto.
1278 (handle_function): Ditto.
1280 2006-02-14 Paul D. Smith <psmith@gnu.org>
1282 * read.c (eval): Even if the included filenames expands to the
1283 empty string we still need to free the allocated buffer.
1285 * implicit.c (pattern_search): If we allocated a variable set for
1286 an impossible file, free it.
1287 * variable.c (free_variable_set): New function.
1288 * variable.h: Declare it.
1290 * read.c (read_all_makefiles): Makefile names are kept in the
1291 strcache, so there's never any need to alloc/free them.
1292 (eval): Ditto.
1294 * main.c (main): Add "archives" to the .FEATURES variable if
1295 archive support is enabled.
1296 * doc/make.texi (Special Variables): Document it.
1298 2006-02-13 Paul D. Smith <psmith@gnu.org>
1300 * implicit.c (pattern_search): Add checking for DOS pathnames to
1301 the pattern rule target LASTSLASH manipulation.
1302 Fixes Savannah bug #11183.
1304 2006-02-11 Paul D. Smith <psmith@gnu.org>
1306 * (ALL FILES): Updated copyright and license notices.
1308 2006-02-10 Paul D. Smith <psmith@gnu.org>
1310 A new internal capability: the string cache is a read-only cache
1311 of strings, with a hash table interface for fast lookup. Nothing
1312 in the cache will ever be freed, so there's no need for reference
1313 counting, etc. This is the beginning of a full solution for
1314 Savannah bug #15182, but for now we only store makefile names here.
1316 * strcache.c: New file. Implement a read-only string cache.
1317 * make.h: Add prototypes for new functions.
1318 * main.c (initialize_global_hash_tables): Initialize the string cache.
1319 (print_data_base): Print string cache stats.
1320 * read.c (eval_makefile): Use the string cache to store makefile
1321 names. Rewrite the string allocation to be sure we free everything.
1323 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1325 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1326 directory time stamp didn't change, except on FAT filesystems.
1327 Suggested by J. David Bryan <jdbryan@acm.org>.
1329 2006-02-09 Paul D. Smith <psmith@gnu.org>
1331 * function.c (func_or): Implement a short-circuiting OR function.
1332 (func_and): Implement a short-circuiting AND function.
1333 (function_table_init): Update the table with the new functions.
1334 * doc/make.texi (Conditional Functions): Changed the "if" section
1335 to one on general conditional functions. Added documentation for
1336 $(and ...) and $(or ...) functions.
1337 * NEWS: Note new $(and ...) and $(or ...) functions.
1339 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1341 * job.h (struct child): Add the dontcare bitfield.
1342 * job.c (new_job): Cache dontcare flag.
1343 * job.c (reap_children): Use cached dontcare flag instead of the
1344 one in struct file. Fixes Savannah bug #15641.
1346 2006-02-06 Paul D. Smith <psmith@gnu.org>
1348 * vpath.c (selective_vpath_search): If the file we find has a
1349 timestamp from -o or -W, use that instead of the real time.
1350 * remake.c (f_mtime): If the mtime is a special token from -o or
1351 -W, don't overwrite it with the real mtime.
1352 Fixes Savannah bug #15341.
1354 Updates from Markus Mauhart <qwe123@chello.at>:
1356 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1357 (process_signal, process_last_err, process_exit_code): Manage
1358 invalid handle values.
1359 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1360 manage invalid handles; remove them.
1361 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1362 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1363 * README.cvs: Updates for building from CVS.
1365 2006-02-05 Paul D. Smith <psmith@gnu.org>
1367 * file.c (enter_file): Keep track of the last double_colon entry,
1368 to avoid walking the list every time we want to add a new one.
1369 Fixes Savannah bug #15533.
1370 * filedef.h (struct file): Add a new LAST pointer.
1372 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1373 the comparison. For 64-bits systems the result of the subtraction
1374 might not fit into an int. Use comparison instead.
1375 Fixes Savannah bug #15534.
1377 * doc/make.texi: Update the chapter on writing commands to reflect
1378 the changes made in 3.81 for backslash/newline and SHELL handling.
1380 2006-02-01 Paul D. Smith <psmith@gnu.org>
1382 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1383 variable st is not used when it's not initialized.
1384 Patch from Eli Zaretskii <eliz@gnu.org>.
1386 2006-01-31 Paul D. Smith <psmith@gnu.org>

1392 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1393 J. Grant <jg@jguk.org>.
1395 * main.c: Update the copyright year in the version output.
1396 * prepare_w32.bat: Remove this file from the distribution.
1398 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1400 * remake.c (update_goal_chain): Set g->changed instead of
1401 incrementing it, as it is only 8-bit wide, and could overflow if
1402 many commands got started in update_file.
1404 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1406 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1407 MAXIMUM_WAIT_OBJECTS.
1408 (process_wait_for_any_private): Change dimension of handles[]
1409 array to MAXIMUM_WAIT_OBJECTS.
1410 (process_used_slots): New function.
1411 (process_register): Don't register more processes than the
1412 available number of slots.
1413 (process_easy): Don't start new processes if all slots are used up.
1415 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1416 are already more children than sub_proc.c can handle, behave as if
1417 the load were too high.
1418 (start_job_command): Fix a typo in error message when process_easy
1419 fails.
1421 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1423 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1424 the shell is not sh.exe.
1426 * job.c (create_batch_file): Renamed from create_batch_filename;
1427 all callers changed. Don't close the temporary file; return its
1428 file descriptor instead. New arg FD allows to return the file
1429 descriptor.
1430 (construct_command_argv_internal): Use _fdopen instead of fopen to
1431 open the batch file.
1433 2006-01-04 Paul D. Smith <psmith@gnu.org>
1435 * readme.vms: Updates for case-insensitive VMS file systems from
1436 Hartmut Becker <Hartmut.Becker@hp.com>.

1448 doesn't exist.
1450 * read.c (eval): Be sure to strip off trailing whitespace from the

1452 struct dep when creating a new one.
1454 2005-12-28 Paul D. Smith <psmith@gnu.org>
1456 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1457 disable warnings for MSC.
1458 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1460 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1462 * doc/make.texi (Execution): Add a footnote about changes in
1463 handling of backslash-newline sequences. Mention the differences
1464 on MS-DOS and MS-Windows.
1466 * NEWS: More details about building the MinGW port and a pointer
1467 to README.W32. Fix the section name that describes the new
1468 backward-incompatible processing of backslash-newline sequences.
1469 The special processing of SHELL set to "cmd" is only relevant to
1470 MS-Windows, not MS-DOS.
1472 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1474 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1475 to DWORD, to avoid compiler warnings.
1476 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1477 use %ld in format, to avoid compiler warnings.
1479 * doc/make.texi (Special Targets): Fix a typo.
1480 (Appending): Fix cross-reference to Setting.
1481 (Special Variables, Secondary Expansion, File Name Functions)
1482 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1483 periods after a sentence.
1484 (Execution): Add @: after "e.g.".
1485 (Environment): Fix punctuation.
1486 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1487 (Shell Function, Target-specific): Add @: after "vs."
1489 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1491 * read.c (record_target_var): Initialize variable's export field
1492 with v_default instead of leaving it "initialized" by whatever
1493 garbage happened to be on the heap.
1495 2005-12-12 Paul D. Smith <psmith@gnu.org>
1497 * make.1: Fix some display errors and document all existing options.
1498 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1500 2005-12-11 Paul D. Smith <psmith@gnu.org>
1502 * implicit.c (pattern_search): If 2nd expansion is not set for
1503 this implicit rule, replace the pattern with the stem directly,
1504 and don't re-expand the variable list. Along with the other
1505 .SECONDEXPANSION changes below, fixes bug #13781.
1507 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1509 * implicit.c (pattern_search): Mark other files that this rule
1510 builds as targets so that they are not treated as intermediates
1511 by the pattern rule search algorithm. Fixes bug #13022.
1513 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1515 * remake.c (notice_finished_file): Propagate the change of
1516 modification time to all the double-colon entries only if
1517 it is the last one to be updated. Fixes bug #14334.
1519 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1521 * function.c (func_flavor): Implement the flavor function which
1522 returns the flavor of a variable.
1523 * doc/make.texi (Functions for Transforming Text): Document it.
1524 * NEWS: Add it to the list of new functions.
1526 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1528 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1529 variable.
1530 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1531 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1533 2005-10-26 Paul Smith <psmith@gnu.org>
1535 * read.c (record_files): Don't set deps flags if there are no deps.
1536 * maintMakefile: We only need to build the templates when we are
1537 creating a distribution, so don't do it for "all".
1539 2005-10-24 Paul D. Smith <psmith@gnu.org>

1548 prerequisite list was found in a static pattern rule.
1549 (free_dep_chain): Declare a prototype.
1550 * file.c (parse_prereqs): New function: break out some complexity
1551 from expand_deps().
1552 (expand_deps): If we aren't doing second expansion, replace % with
1553 the stem for static pattern rules. Call the new function.
1554 * filedef.h (parse_prereqs): Declare a prototype.
1555 * implicit.c (pattern_search): Initialize the new staticpattern
1556 field.
1557 * main.c (second_expansion): Declare a global variable to remember
1558 if the special target has been seen. Initialize the new
1559 staticpattern field for prerequisites.
1560 * make.h: Extern for second_expansion.
1561 * misc.c (free_dep_chain): New function: frees a struct dep list.
1562 * read.c (read_all_makefiles): Initialize the staticpattern field.
1563 (eval_makefile): Ditto.
1564 (record_files): Check for the .SECONDEXPANSION target and set
1565 second_expansion global if it's found.
1566 Use the new free_dep_chain() instead of doing it by hand.
1567 Set the staticpattern field for prereqs of static pattern targets.
1569 2005-10-16 Paul D. Smith <psmith@gnu.org>
1571 * main.c (main): Set CURDIR to be a file variable instead of a
1572 default, so that values of CURDIR inherited from the environment
1573 won't override the make value.
1575 2005-09-26 Paul D. Smith <psmith@gnu.org>
1577 * job.c (construct_command_argv_internal): If the line is empty
1578 remember to free the temporary argv strings.
1579 Fixes bug # 14527.
1581 2005-09-16 Paul D. Smith <psmith@gnu.org>
1583 * job.c (start_job_command): The noerror flag is a boolean (single
1584 bit); set it appropriately.
1585 Reported by Mark Eichin <eichin@metacarta.com>
1587 2005-08-29 Paul D. Smith <psmith@gnu.org>
1589 * function.c (func_error): On Windows, output from $(info ...)
1590 seems to come in the wrong order. Try to force it with fflush().
1592 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1594 * read.c (record_files): Move code that sets stem for static
1595 pattern rules out of the if (!two_colon) condition so it is
1596 also executed for two-colon rules. Fixes Savannah bug #13881.
1598 2005-08-08 Paul D. Smith <psmith@gnu.org>
1600 * make.h: Don't test that __STDC__ is non-0. Some compilers
1601 (Windows for example) set it to 0 to denote "ISO C + extensions".
1602 Fixes bug # 13594.
1604 2005-08-07 Paul D. Smith <psmith@gnu.org>
1606 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1607 conditional (slightly different version of a fix from Eli).
1609 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1610 If make is running in parallel without -k and two jobs die in a
1611 row, but not too close to each other, then make will quit without
1612 waiting for the rest of the jobs to die.
1614 * main.c (die): Don't reset err before calling reap_children() the
1615 second time: we still want it to be in the error condition.
1616 * job.c (reap_children): Use a static variable, rather than err,
1617 to control whether or not the error message should be printed.
1619 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1621 * w32/subproc/sub_proc.c: Include signal.h.
1622 (process_pipe_io, process_file_io): Pass a pointer to a local
1623 DWORD variable to GetExitCodeProcess. If the exit code is
1624 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1626 * job.c [WINDOWS32]: Include windows.h.
1627 (main_thread) [WINDOWS32]: New global variable.
1628 (reap_children) [WINDOWS32]: Get the handle for the main thread
1629 and store it in main_thread.
1631 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1632 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1633 doing anything else. When we are done, close the main thread
1634 handle and exit with status 130.
1636 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1638 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1639 pointer to fprintf.
1641 * main.c (find_and_set_default_shell): If found a DOSish shell,
1642 set sh_found and the value of default_shell, and report the
1643 findings in debug mode.
1645 * job.c (construct_command_argv_internal): Check unixy_shell, not
1646 no_default_sh_exe, to decide whether to use Unixy or DOSish
1647 builtin commands.
1649 * README.W32: Update with info about the MinGW build.
1651 * build_w32.bat: Support MinGW.
1653 * w32/subproc/build.bat: Likewise.
1655 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1656 printing DWORD args.
1658 * function.c (windows32_openpipe): Fix format strings for printing
1659 DWORD args.
1661 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1662 'reap_mode'.
1663 (start_job_command): Fix format string for printing the result of
1664 process_easy.
1665 (start_job_command) [WINDOWS32]: Do not define.
1666 (exec_command): Fix format string for printing HANDLE args.
1668 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1669 to avoid compiler warnings.
1670 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1671 (Note: some of these fixes were submitted independently by J. Grant)
1673 2005-07-30 J. Grant <jg@jguk.org>
1675 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1676 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1677 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1679 2005-07-15 Paul Smith <psmith@gnu.org>
1681 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1682 we don't have a POSIX shell, then revert to the old
1683 backslash-newline behavior (where they are stripped).
1684 Fixes bug #13665.
1686 2005-07-08 Paul D. Smith <psmith@gnu.org>
1688 * config.h.W32.template: Reorder to match the standard config.h,
1689 for easier comparisons.
1690 From J. Grant <jg@jguk.org>
1692 * maintMakefile: Remove .dep_segment before overwriting it, in
1693 case it's not writable or noclobber is set.
1694 * expand.c (variable_expand_string): Cast result of pointer
1695 arithmetic to avoid a warning.
1696 * main.c (switches): Add full-fledged final initializer.
1698 2005-07-06 Paul D. Smith <psmith@gnu.org>
1700 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1701 * signame.c (strsignal): If we found _sys_siglist[] or
1702 __sys_siglist[] use those instead of sys_siglist[].
1703 From Albert Chin <china@thewrittenword.com>
1705 2005-07-04 Paul D. Smith <psmith@gnu.org>
1707 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1708 globfree(); set up to use the GNU versions.
1709 From Martin Zinser <zinser@zinser.no-ip.info>
1711 2005-07-03 Paul D. Smith <psmith@gnu.org>
1713 From J. Grant <jg@jguk.org>:
1715 * README.W32.template: Update the Windows and tested MSVC versions.
1716 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1717 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1718 * build_w32.bat: Ditto.
1719 * w32/subproc/build.bat: Ditto.
1721 2005-06-28 Paul D. Smith <psmith@gnu.org>
1723 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1724 declaration was checked but not present.
1726 2005-06-27 Paul D. Smith <psmith@gnu.org>
1728 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1729 to unsigned long. Fixes Savannah bug #13550.
1731 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1732 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1733 Fixes Savannah bug #13551.
1735 2005-06-26 Paul D. Smith <psmith@gnu.org>
1737 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1738 it if ANSI_STRING is not set.
1740 2005-06-25 Paul D. Smith <psmith@gnu.org>
1742 * read.c (eval): If no filenames are passed to any of the
1743 "include" variants, don't print an error.
1744 * doc/make.texi (Include): Document this.
1745 Fixes Savannah bug #1761.
1747 * job.c (construct_command_argv_internal): Sanitize handling of
1748 backslash/newline pairs according to POSIX: that is, keep the
1749 backslash-newline in the command script, but remove a following
1750 TAB character, if present. In the fast path, make sure that the
1751 behavior matches what the shell would do both inside and outside
1752 of quotes. In the slow path, quote the backslash and put a
1753 literal newline in the string.
1754 Fixes Savannah bug #1332.
1755 * doc/make.texi (Execution): Document the new behavior and give
1756 some examples.
1757 * NEWS: Make a note of the new behavior.
1759 * make.h [WINDOWS32]: #include <direct.h>.
1760 Fixes Savannah bug #13478.
1762 * remake.c (name_mtime): If the stat() of a file fails and the -L
1763 option was given and the file is a symlink, take the best mtime of
1764 the symlink we can get as the mtime of the file and don't fail.
1765 Fixes Savannah bug #13280.
1767 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1768 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1769 inside a variable reference. Make this function static as it's
1770 only used here.
1771 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1772 parsing an unexpanded line looking for semicolons.
1773 Fixes Savannah bug #1454.
1774 * misc.c (remove_comments): Move this to read.c and make it static
1775 as it's only used there. Call find_char_unquote() with new arg.
1776 * make.h: Remove prototypes for find_char_unquote() and
1777 remove_comments() since they're static now.
1779 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1780 its export flag and obtain its value. When we need to re-exec,
1781 increment the value and add it into the environment.
1782 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1783 * NEWS: Mention MAKE_RESTARTS.
1784 * main.c (always_make_set): New variable. Change the -B option to
1785 set this one instead.
1786 (main): When checking makefiles, only set always_make_flag if
1787 always_make_set is set AND the restarts flag is 0. When building
1788 normal targets, set it IFF always_make_set is set.
1789 (main): Avoid infinite recursion with -W, too: only set what-if
1790 files to NEW before we check makefiles if we've never restarted
1791 before. If we have restarted, set what-if files to NEW _after_ we
1792 check makefiles.
1793 Fixes Savannah bug #7566:
1795 2005-06-17 Paul D. Smith <psmith@gnu.org>
1797 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1798 in the prerequisites list.
1800 2005-06-12 Paul D. Smith <psmith@gnu.org>
1802 Fix Savannah bug # 1328.
1804 * configure.in: Check for atexit().
1805 * misc.c (close_stdout): Test stdout to see if writes to it have
1806 failed. If so, be sure to exit with a non-0 error code. Based on
1807 code found in gnulib.
1808 * make.h: Prototype.
1809 * main.c (main): Install close_stdout() with atexit().
1811 2005-06-10 Paul D. Smith <psmith@gnu.org>
1813 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1815 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1816 headers; make vmsWaitForChildren() static; extern vmsify().
1817 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1818 Don't create child_execute_job() here (it's in vmsjobs.c).
1819 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1821 2005-06-09 Paul D. Smith <psmith@gnu.org>
1823 * variable.c (push_new_variable_scope): File variables point
1824 directly to the global_setlist variable. So, inserting a new
1825 scope in front of that has no effect on those variables: they
1826 don't go through current_variable_set_list. If we're pushing a
1827 scope and the current scope is global, push it "the other way" so
1828 that the new setlist is in the global_setlist variable, and
1829 next points to a new setlist with the global variable set.
1830 (pop_variable_scope): Properly undo a push with the new
1831 semantics.
1832 Fixes Savannah bug #11913.
1834 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1836 * job.c (reap_children): Don't die of the command failed but
1837 the dontcare flag is set. Fixes Savannah bug #13216.
1839 * implicit.c (pattern_search): When creating a target from
1840 an implicit rule match, lookup pattern target and set precious
1841 flag in a newly created target. Fixes Savannah bug #13218.
1843 2005-05-13 Paul D. Smith <psmith@gnu.org>
1845 Implement "if... else if... endif" syntax.
1847 * read.c (eval): Push all checks for conditional words ("ifeq",
1848 "else", etc.) down into the conditional_line() function.
1849 (conditional_line): Rework to allow "else if..." clause. New
1850 return value -2 for lines which are not conditionals. The
1851 ignoring flag can now also be 2, which means "already parsed a
1852 true branch". If that value is seen no other branch of this
1853 conditional can be considered true. In the else parsing if there
1854 is extra text after the else, invoke conditional_line()
1855 recursively to see if it's another conditional. If not, it's an
1856 error. If so, raise the conditional value to this level instead
1857 of creating a new conditional nesting level. Special check for
1858 "else" and "endif", which aren't allowed on the "else" line.
1859 * doc/make.texi (Conditional Syntax): Document the new syntax.
1861 2005-05-09 Paul D. Smith <psmith@gnu.org>
1863 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1864 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1865 recurses to the w32 directory, even on non-Windows systems. Use
1866 the method suggested in the automake manual.
1867 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1868 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1870 2005-05-07 Paul D. Smith <psmith@gnu.org>
1872 * main.c (die): If we're dying with a fatal error (not that a
1873 command has failed), write back any leftover tokens before we go.
1875 * job.c (set_child_handler_action_flags): If there are jobs
1876 waiting for the load to go down, set an alarm to go off in 1
1877 second. This allows us to wake up from a potentially long-lasting
1878 read() and start a new job if the load has gone down. Turn it off
1879 after the read.
1880 (job_noop): Dummy signal handler function.
1881 (new_job): Invoke it with the new semantics.
1883 * docs/make.texi: Document secondary expansion. Various cleanups
1884 and random work.
1886 2005-05-03 Paul D. Smith <psmith@gnu.org>
1888 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1889 the targets which are to ultimately be made are called "goals";
1890 see the GNU make manual. Also, MAKECMDGOALS, etc.
1892 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1893 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1894 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1896 2005-05-02 Paul D. Smith <psmith@gnu.org>
1898 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1899 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1900 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1901 functions to vmsjobs.c. #include it into jobs.c.
1903 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1904 jobserver tokens. I found that this happens when an exported
1905 recursive variable contains a $(shell ...) function reference: in
1906 this situation we could "forget" to write back a token.
1908 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1909 we have. It's not reliable to depend on the number of children in
1910 our linked list so keep a separate count.
1911 (new_job): Check jobserver_tokens rather than children &&
1912 waiting_jobs. Increment jobserver_tokens when we get one.
1913 (free_child): If jobserver_tokens is 0, internal error. If it's
1914 >1, write a token back to the jobserver pipe (we don't write a
1915 token for the "free" job). Decrement jobserver_tokens.
1917 * main.c: Add variable master_job_slots.
1918 (main): Set it to hold the number of jobs requested if we're the
1919 master process, when using the jobserver.
1920 (die): Sanity checks: first test jobserver_tokens to make sure
1921 this process isn't holding any tokens we didn't write back.
1922 Second, if master_job_slots is set count the tokens left in the
1923 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1925 2005-04-24 Paul D. Smith <psmith@gnu.org>
1927 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1928 with -l# can lose jobserver tokens, because waiting jobs are not
1929 consulted properly when checking for the "free" token.
1931 * job.c (free_child): Count waiting_jobs as having tokens.
1932 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1933 handle jobs waiting for the load to drop.
1935 2005-04-23 Paul D. Smith <psmith@gnu.org>
1937 * main.c (main): Be careful to not core if a variable setting in
1938 the environment doesn't contain an '='. This is illegal but can
1939 happen in broken setups.
1940 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1942 2005-04-12 Paul D. Smith <psmith@gnu.org>
1944 The second expansion feature causes significant slowdown. Timing
1945 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1946 read the makefile before the feature, to 11+s to do the same
1947 operations after the feature. Additionally, memory usage
1948 increased drastically. To fix this I added some intelligence that
1949 avoids the overhead of the second expansion unless it's required.
1951 * dep.h: Add a new boolean field, need_2nd_expansion.
1953 * read.c (eval): When creating the struct dep for the target,
1954 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1955 (record_files): If there's a "%" in a static pattern rule, it gets
1956 converted to "$*" so set need_2nd_expansion to 1.
1958 * file.c (expand_deps): Rework to be more efficient. Only perform
1959 initialize_file_variables(), set_file_variables(), and
1960 variable_expand_for_file() if the need_2nd_expansion is set.
1962 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1963 (pattern_search): Ditto.
1964 * main.c (handle_non_switch_argument): Ditto.
1965 (main): Ditto.
1966 * read.c (read_all_makefiles): Ditto.
1967 (eval_makefile): Ditto.
1969 2005-04-07 Paul D. Smith <psmith@gnu.org>
1971 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1972 * variable.c (sync_Path_environment): Ditto.
1973 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1975 * main.c (main): Define the .FEATURES variable.
1976 * NEWS: Announce .FEATURES.
1977 * doc/make.texi (Special Variables): Document .FEATURES.
1979 * remake.c (check_dep): If a file is .PHONY, update it even if
1980 it's marked intermediate. Fixes Savannah bug #12331.
1982 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1984 * file.c (expand_deps): Factor out the second expansion and
1985 prerequisite line parsing logic from snap_deps().
1987 * file.c (snap_deps): Use expand_deps(). Expand and parse
1988 prerequisites of the .SUFFIXES special target first. Fixes
1989 Savannah bug #12320.
1991 2005-03-13 Paul D. Smith <psmith@gnu.org>
1993 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1994 Zaretskii.
1996 2005-03-11 Paul D. Smith <psmith@gnu.org>
1998 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1999 available, not undefined (from Earnie Boyd).
2001 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2003 * implicit.c (pattern_search): Mark an intermediate target as
2004 precious if it happened to be a prerequisite of some (other)
2005 target. Fixes Savannah bug #12267.
2007 2005-03-09 Paul D. Smith <psmith@gnu.org>
2009 * read.c (eval_makefile): Add alloca(0).
2010 (eval_buffer): Ditto.
2012 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2014 * main.c (main): Use o_file instead of o_default when defining
2015 the .DEFAULT_TARGET special variable.
2016 * read.c (eval): Use define_variable_global() instead of
2017 define_variable() when setting new value for the .DEFAULT_TARGET
2018 special variable. Fixes Savannah bug #12266.
2020 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2022 * imlicit.c (pattern_search): Mark files for which an implicit
2023 rule has been found as targets. Fixes Savannah bug #12202.
2025 2005-03-04 Paul D. Smith <psmith@gnu.org>
2027 * AUTHORS: Update.
2028 * doc/make.texi (Automatic Variables): Document $|.
2030 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2032 * read.c (record_files): Instead of substituting % with
2033 actual stem value in dependency list replace it with $*.
2034 This fixes stem triple expansion bug.
2036 * implicit.c (pattern_search): Copy stem to a separate
2037 buffer and make it a properly terminated string. Assign
2038 this buffer instead of STEM (which is not terminated) to
2039 f->stem. Instead of substituting % with actual stem value
2040 in dependency list replace it with $*. This fixes stem
2041 triple expansion bug.
2043 2005-03-01 Paul D. Smith <psmith@gnu.org>
2045 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2046 on Windows, as it takes a handle not a pid. Just exit.
2047 Fix from patch #3679, provided by Alessandro Vesely.
2049 * configure.in: Update check for sys_siglist[] from autoconf manual.
2050 * signame.c (strsignal): Update to use the new autoconf macro.
2052 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2054 * read.c (record_files): Add a check for the list of prerequisites
2055 of a static pattern rule being empty. Fixes Savannah bug #12180.
2057 2005-02-28 Paul D. Smith <psmith@gnu.org>
2059 * doc/make.texi (Text Functions): Update docs to allow the end
2060 ordinal for $(wordlist ...) to be 0.
2061 * function.c (func_wordlist): Fail if the start ordinal for
2062 $(wordlist ...) is <1. Matches documentation.
2063 Resolves Savannah support request #103195.
2065 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2066 previously we were stopping when !-q, exactly the opposite. This
2067 has been wrong since version 1.34, in 1994!
2068 (update_file): If we got an error don't break out to run more
2069 double-colon rules: just return immediately.
2070 Fixes Savannah bug #7144.
2072 2005-02-27 Paul D. Smith <psmith@gnu.org>
2074 * misc.c (end_of_token): Make argument const.
2075 * make.h: Update prototype.
2077 * function.c (abspath, func_realpath, func_abspath): Use
2078 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2079 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2080 * read.c (record_files): Ditto.
2081 * variable.c (do_variable_definition): Ditto.
2083 * function.c (func_error): Create a new function $(info ...) that
2084 simply prints the message to stdout with no extras.
2085 (function_table_init): Add new function to the table.
2086 * NEWS: Add $(info ...) reference.
2087 * doc/make.texi (Make Control Functions): Document it.
2089 New feature: if the system supports symbolic links, and the user
2090 provides the -L/--check-symlink-time flag, then use the latest
2091 mtime between the symlink(s) and the target file.
2093 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2094 readlink(). If both are available, define MAKE_SYMLINKS.
2095 * main.c: New variable: check_symlink_flag.
2096 (usage): Add a line for -L/--check-symlink-times to the help string.
2097 (switches): Add -L/--check-symlink-times command line argument.
2098 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2099 print a warning and disable it again.
2100 * make.h: Declare check_symlink_flag.
2101 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2102 if the file is a symlink then check each link in the chain and
2103 choose the NEWEST mtime we find as the mtime for the file. The
2104 newest mtime might be the file itself!
2105 * NEWS: Add information about this new feature.
2106 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2108 Avoid core dumps described in Savannah bug # 12124:
2110 * file.c: New variable snapped_deps remember whether we've run
2111 snap_deps().
2112 (snap_deps): Set it.
2113 * filedef.h: Extern it.
2114 * read.c (record_files): Check snapped_deps; if it's set then
2115 we're trying to eval a new target/prerequisite relationship from
2116 within a command script, which we don't support. Fatal.
2118 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2120 Implementation of the .DEFAULT_TARGET special variable.
2122 * read.c (eval): If necessary, update default_target_name when
2123 reading rules.
2124 * read.c (record_files): Update default_target_file if
2125 default_target_name has changed.
2126 * main.c (default_target_name): Define.
2127 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2128 default_target_name is set use default_target_file as a root
2129 target to make.
2130 * filedef.h (default_target_name): Declare.
2131 * dep.h (free_dep_chain):
2132 * misc.c (free_dep_chain): Change to operate on struct nameseq
2133 and change name to free_ns_chain.
2134 * file.c (snap_deps): Update to use free_ns_chain.
2136 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2138 Implementation of the second expansion in explicit rules,
2139 static pattern rules and implicit rules.
2141 * read.c (eval): Refrain from chopping up rule's dependencies.
2142 Store them in a struct dep as a single dependency line. Remove
2143 the code that implements SySV-style automatic variables.
2145 * read.c (record_files): Adjust the code that handles static
2146 pattern rules to expand all percents instead of only the first
2147 one. Reverse the order in which dependencies are stored so that
2148 when the second expansion reverses them again they appear in
2149 the makefile order (with some exceptions, see comments in
2150 the code). Remove the code that implements SySV-style automatic
2151 variables.
2153 * file.c (snap_deps): Implement the second expansion and chopping
2154 of dependency lines for explicit rules.
2156 * implicit.c (struct idep): Define an auxiliary data type to hold
2157 implicit rule's dependencies after stem substitution and
2158 expansion.
2160 * implicit.c (free_idep_chain): Implement.
2162 * implicit.c (get_next_word): Implement helper function for
2163 parsing implicit rule's dependency lines into words taking
2164 into account variable expansion requests. Used in the stem
2165 splitting code.
2167 * implicit.c (pattern_search): Implement the second expansion
2168 for implicit rules. Also fixes bug #12091.
2170 * commands.h (set_file_variables): Declare.
2171 * commands.c (set_file_variables): Remove static specifier.
2173 * dep.h (free_dep_chain): Declare.
2174 * misc.c (free_dep_chain): Implement.
2176 * variable.h (variable_expand_for_file): Declare.
2177 * expand.c (variable_expand_for_file): Remove static specifier.
2179 * make.h (strip_whitespace): Declare.
2180 * function.c (strip_whitespace): Remove static specifier.
2182 2005-02-26 Paul D. Smith <psmith@gnu.org>
2184 * main.c (main): Check for ferror() when reading makefiles from stdin.
2185 Apparently some shells in Windows don't close pipes properly and
2186 require this check.
2188 2005-02-24 Jonathan Grant <jg@jguk.org>
2190 * configure.in: Add MinGW configuration options, and extra w32 code
2191 directory.
2192 * Makefile.am: Add MinGW configuration options, and extra w32 code
2193 directory.
2194 * main.c: Determine correct program string (after last \ without .exe).
2195 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2196 type fix x2
2197 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2198 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2199 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2200 environment support.
2202 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2204 * function.c (func_shell): When initializing error_prefix, check
2205 that reading file name is not null. This fixes long-standing
2206 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2208 2005-02-09 Paul D. Smith <psmith@gnu.org>
2210 * maintMakefile: Update the CVS download URL to simplify them.
2211 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2212 downloading the .texi files from Savannah now.
2214 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2216 * main.c (handle_non_switch_argument): Only add variables to
2217 command_variables if they're not already there: duplicate settings
2218 waste space and can be confusing to read.
2220 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2221 this header is never included by non-WINDOWS32 code, and it
2222 requires <config.h> to define which isn't always included first.
2224 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2225 testing MINGW32 versions.
2227 * main.c (log_working_directory): flush stdout to be sure the WD
2228 change is printed before any stderr messages show up.
2230 2005-02-01 Paul D. Smith <psmith@gnu.org>
2232 * maintMakefile (po_repo): Update the GNU translation site URL.
2234 2004-12-01 Paul D. Smith <psmith@gnu.org>
2236 * main.c (main): Change char* env_shell to struct variable shell_var.
2237 * variable.c (target_environment): Use new shell_var.
2239 2004-11-30 Paul D. Smith <psmith@gnu.org>
2241 * configure.in: The old way we avoided creating build.sh from
2242 build.sh.in before build.sh.in exists doesn't work anymore; we
2243 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2244 the help!). This also keeps automake from complaining.
2245 * Makefile.am (README): Add a dummy target so automake won't
2246 complain that this file doesn't exist when we checkout from CVS.
2247 * maintMakefile (.dep_segment): Rewrite this rule since newer
2248 versions of automake don't provide DEP_FILES.
2250 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2252 Implementation of `realpath' and `abspath' built-in functions.
2254 * configure.in: Check for realpath.
2255 * function.c (abspath): Return an absolute file name that does
2256 not contain any `.' or `..' components, nor repeated `/'.
2257 * function.c (func_abspath): For each name call abspath.
2258 * function.c (func_realpath): For each name call realpath
2259 from libc or delegate to abspath if realpath is not available.
2260 * doc/make.texi (Functions for File Names): Document new functions.
2261 * doc/make.texi (Quick Reference): Ditto.
2263 2004-11-28 Paul D. Smith <psmith@gnu.org>
2265 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2266 arguments. Fixes bug #10252.
2268 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2270 * main.c (main): Set SHELL to v_noexport by default. Remember the
2271 original environment setting of SHELL in the env_shell variable.
2272 * main.h: Export new env_shell variable.
2273 * variable.c (target_environment): If we find a v_noexport
2274 variable for SHELL, add a SHELL variable with the env_shell value.
2275 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2276 * doc/make.texi (Variables/Recursion): Ditto.
2278 2004-11-28 Paul D. Smith <psmith@gnu.org>
2280 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2281 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2282 Patch by Alessandro Vesely.
2284 2004-11-12 Paul D. Smith <psmith@gnu.org>
2286 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2287 the command line if it's inside a string.
2288 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2290 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2292 * function.c (func_lastword): New function: return last word
2293 from the list of words.
2294 * doc/make.texi: Document $(lastword ). Fix broken links in
2295 Quick Reference section.
2297 2004-10-06 Paul D. Smith <psmith@gnu.org>
2299 Apply patch from Alessandro Vesely, provided with bug # 9748.
2300 Fix use of tmpnam() to work with Borland C.
2302 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2303 construction of a temporary filename, and call new function
2304 create_batch_filename().
2305 (create_batch_filename) [WINDOWS32]: New function to create a
2306 temporary filename.
2308 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2310 * read.c (record_target_var): Expand simple pattern-specific
2311 variable.
2312 * variable.c (initialize_file_variables): Do not expand simple
2313 pattern-specific variable.
2315 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2317 * remake.c (update_file_1): When rebuilding makefiles inherit
2318 dontcare flag from a target that triggered update.
2320 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2322 * variable.c (initialize_file_variables): Mark pattern-specific
2323 variable as a per-target and copy export status.
2325 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2327 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2329 * implicit.c (pattern_search): When considering an implicit rule's
2330 prerequisite check that it is actually a target rather then
2331 just an entry in the file hashtable.
2333 2004-09-21 Paul D. Smith <psmith@gnu.org>
2335 * read.c (readstring): Fix some logic errors in backslash handling.
2336 (eval): Remove some unnecessary processing in buffer handling.
2337 (record_target_var): Assert that parse_variable_definition() succeeded.
2338 Reported by: Markus Mauhart <qwe123@chello.at>.
2340 * misc.c: Removed the sindex() function. All instances of this
2341 function were trivially replaceable by the standard strstr()
2342 function, and that function will always have better (or certainly
2343 no worse) performance than the very simple-minded algorithm
2344 sindex() used. This can matter with complex makefiles.
2345 * make.h: Remove the prototype for sindex().
2346 * function.c (subst_expand): Convert sindex() call to strstr().
2347 This means we no longer need to track the TLEN value so remove that.
2348 (func_findstring): Convert sindex() to strstr().
2349 * commands.c (chop_commands): Convert sindex() calls to strstr().
2350 Suggested by: Markus Mauhart <qwe123@chello.at>.
2352 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2353 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2354 If SHELL is set to CMD.EXE then assume it's batch-mode and
2355 non-unixy. I wrote the code differently from the patch, though,
2356 to make it safer. This also resolves bug #9174.
2358 2004-09-20 Paul D. Smith <psmith@gnu.org>
2360 * expand.c (variable_expand_string): Modify to invoke
2361 patsubst_expand() instead of subst_expand(); the latter didn't
2362 handle suffix patterns correctly.
2363 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2364 was used only from variable_expand_string() and is no longer used
2365 there.
2366 (func_subst): Ditto, on call to subst_expand().
2367 (patsubst_expand): Require the percent pointers to point to the
2368 character after the %, not to the % itself.
2369 * read.c (record_files): New call criteria for patsubst_expand().
2370 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2371 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2373 2004-09-19 Paul D. Smith <psmith@gnu.org>
2375 * function.c (subst_expand): Fix a check in by_word: look for a
2376 previous blank if we're beyond the beginning of the string, not
2377 the beginning of the word.
2378 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2380 2004-05-16 Paul D. Smith <psmith@gnu.org>
2382 * remake.c (update_goal_chain): Change the argument specifying
2383 whether we're rebuilding makefiles to be a global variable,
2384 REBUILDING_MAKEFILES.
2385 (complain): Extract the code that complains about no rules to make
2386 a target into a separate function.
2387 (update_file_1): If we tried to rebuild a file during the makefile
2388 rebuild phase and it was dontcare, then no message was printed.
2389 If we then try to build the same file during the normal build,
2390 print a message this time.
2391 (remake_file): Don't complain about un-remake-able files when
2392 we're rebuilding makefiles.
2394 2004-05-11 Paul D. Smith <psmith@gnu.org>
2396 * job.c (construct_command_argv_internal): OS/2 patches from
2397 Andreas Buening <andreas.buening@nexgo.de>.
2399 2004-05-10 Paul D. Smith <psmith@gnu.org>
2401 * remake.c (update_file): Don't walk the double-colon chain unless
2402 this is a double-colon rule. Fix suggested by Boris Kolpackov
2403 <boris@kolpackov.net>.
2405 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2406 * readme.vms: New section describing OpenVMS support and issues.
2407 * default.c (default_variables): Add support for IA64.
2408 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2409 without some privilege aborts make with the error
2410 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2411 pressing Ctrl+Y and the input device is no terminal. The change
2412 catches this error and just continues.
2414 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2416 2004-04-25 Paul D. Smith <psmith@gnu.org>
2418 * commands.c (set_file_variables): Set $< properly in the face of
2419 order-only prerequisites.
2420 Patch from Boris Kolpackov <boris@kolpackov.net>
2422 2004-04-21 Bob Byrnes <byrnes@curl.com>
2424 * main.c (main): Notice failures to remake makefiles.
2426 2004-03-28 Paul D. Smith <psmith@gnu.org>
2428 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2430 * job.c: No default shell for RISC OS.
2431 (load_too_high): Hard-code the return to 1.
2432 (construct_command_argv_internal): No sh_chars or sh_cmds.
2433 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2435 2004-03-20 Paul D. Smith <psmith@gnu.org>
2437 * variable.c (do_variable_definition): Don't append from the
2438 global set if a previous non-appending target-specific variable
2439 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2440 (with fix).
2442 * expand.c (reference_variable): Don't give up on variables with
2443 no value that have the target-specific append flag set: they might
2444 have a value after all. Reported by Oliver Schmidt
2445 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2446 <nikulin@dx1cmd.inp.nsk.su>.
2448 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2449 refer to absolute pathnames in directories that don't exist: some
2450 portion of the makefile could create those directories before we
2451 match the pattern. Fixes bugs #775 and #108.
2453 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2455 * main.c (main): Free makefile_mtimes if we have any.
2456 * README.W32.template: Update documentation for the current status
2457 of the MS-Windows port.
2458 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2459 environment variable is sometimes already defined which causes the
2460 build to fail.
2461 * main.c (debug_signal_handler): Only define this function if
2462 SIGUSR1 is available.
2464 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2466 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2467 * README.OS2.template: Documentation updates.
2468 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2469 link line for safety.
2470 * maintMakefile (build.sh.in): Remove an extraneous ")".
2471 * job.c (child_execute_job): Close saved FDs.
2472 * job.c (exec_command) [OS/2]: exec_command(): If the command
2473 can't be exec'ed and if the shell is not Unix-sh, then try again
2474 with argv = { "cmd", "/c", ... }. Normally, this code is never
2475 reached for the cmd shell unless the command really doesn't exist.
2476 (construct_command_argv_internal) [OS/2]: The code for cmd
2477 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2478 The CMD builtin commands are case insensitive so use strcasecmp().
2480 2004-03-19 Paul D. Smith <psmith@gnu.org>
2482 * read.c (do_define): Re-order line counter increment so the count
2483 is accurate (we were losing one line per define). Reported by
2484 Dave Yost <Dave@Yost.com>.
2486 2004-03-06 Paul D. Smith <psmith@gnu.org>
2488 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2489 compiler.
2490 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2491 * misc.c (message,error,fatal): Ditto.
2492 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2493 * config.h.W32.template: Ditto.
2494 * config.h-vms.template: Ditto.
2495 * config.ami.template: Ditto.
2497 2004-03-04 Paul D. Smith <psmith@gnu.org>
2499 * README.template: Add a note about broken /bin/sh on SunOS
2500 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2502 * misc.c (message, error, fatal): Don't use "..." if we're using
2503 varargs. ansi2knr should handle this but it doesn't work: it
2504 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2505 done. On many systems (SunOS for example) va_dcl is a #define.
2506 So, force the use of the non-"..." version on pre-ANSI compilers.
2508 * maintMakefile (sign-dist): Create some rules to help automate
2509 the new GNU ftp upload method.
2511 2004-02-24 Paul D. Smith <psmith@gnu.org>
2513 * config.h.W32.template: Add HAVE_STDARG_H
2514 * config.h-vms.template: Ditto.
2515 * config.ami.template: Ditto.
2517 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2519 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2520 * build_w32.bat: Remove extra "+".
2522 2004-02-23 Paul D. Smith <psmith@gnu.org>
2524 * make.h: Create an UNUSED macro to mark unused parameters.
2525 * (many): Clean up warnings by applying UNUSED, fixing
2526 signed/unsigned incompatibilities, etc.
2528 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2529 autoconf warnings.
2530 * filedef.h: Name the command_state enumeration.
2531 * file.c (set_command_state): Use the enumeration in the function
2532 argument.
2534 * configure.in: Explicitly set SET_MAKE to empty, to disable
2535 MAKE=make even when no make already exists. Fix bug #3823.
2537 2004-02-22 Paul D. Smith <psmith@gnu.org>
2539 * maintMakefile: Perl script to clean up all non-CVS files. Use
2540 it on all the subdirectories for the cvs-clean target.
2542 * main.c (decode_switches): Require non-empty strings for all our
2543 string command-line options. Fixes Debian bug # 164165.
2545 * configure.in: Check for stdarg.h and varargs.h.
2546 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2547 for printing messages.
2548 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2549 (message): Ditto.
2550 (error): Ditto.
2551 (fatal): Ditto.
2553 A number of patches for OS/2 support from Andreas Buening
2554 <andreas.buening@nexgo.de>:
2556 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2557 disable the SIGCHLD handler.
2558 (reap_children) [OS/2]: Remove special handling of job_rfd.
2559 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2560 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2561 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2562 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2563 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2564 systems.
2566 2004-02-21 Paul D. Smith <psmith@gnu.org>
2568 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2569 <mail@kristov.de> reports that if process_begin() fails we don't
2570 handle the error condition correctly in all cases.
2571 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2572 to have a newline on the message.
2574 * job.c (construct_command_argv_internal): Add "test" to UNIX
2575 sh_cmds[]. Fixes Savannah bug # 7606.
2577 2004-02-04 Paul D. Smith <psmith@gnu.org>
2579 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2580 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2581 Hartmut Becker <Hartmut.Becker@hp.com>.
2583 2004-01-21 Paul D. Smith <psmith@gnu.org>
2585 * job.c (load_too_high): Implement an algorithm to control the
2586 "thundering herd" problem when using -l to control job creation
2587 via the load average. The system only recomputes the load once a
2588 second but we can start many jobs in a second. To solve this we
2589 keep track of the number of jobs started in the last second and
2590 apply a weight to try to guess what a correct load would be.
2591 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2592 Also fixes bug #4693.
2593 (reap_children): Decrease the job count for this second.
2594 (start_job_command): Increase the job count for this second.
2596 * read.c (conditional_line): Expand the text after ifn?def before
2597 checking to see if it's a single word. Fixes bug #7257.
2599 2004-01-09 Paul D. Smith <psmith@gnu.org>
2601 * file.c (print_file): Recurse to print all targets in
2602 double-colon rules. Fixes bug #4518, reported (with patch) by
2603 Andrew Chatham <chatham@google.com>.
2605 2004-01-07 Paul D. Smith <psmith@gnu.org>
2607 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2608 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2609 AC_FUNC_SETVBUF_REVERSED.
2611 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2612 (MAKE Variable): Fix Savannah bug #4898.
2614 * job.c (construct_command_argv_internal): Add "!" to the list of
2615 shell escape chars. POSIX sh allows it to appear before a
2616 command, to negate the exit code. Fixes bug #6404.
2618 * implicit.c (pattern_search): When matching an implicit rule,
2619 remember which dependencies have the ignore_mtime flag set.
2620 Original fix provided in Savannah patch #2349, by Benoit
2621 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2623 2003-11-22 Paul D. Smith <psmith@gnu.org>
2625 * README.W32.template (Outputs): Clarification on -j with
2626 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2627 <jg-make@jguk.org>.
2629 2003-11-02 Paul D. Smith <psmith@gnu.org>
2631 * function.c (func_if): Strip all the trailing whitespace from the
2632 condition, then don't expand it. Fixed bug # 5798.
2634 * expand.c (recursively_expand_for_file): If we're expanding a
2635 variable with no file context, then use the variable's context.
2636 Fixes bug # 6195.
2638 2003-10-21 Paul D. Smith <psmith@gnu.org>
2640 * main.c (log_working_directory): Add newlines to printf()s.
2642 * README.cvs: Add a note to ignore warnings during autoreconf.
2644 * maintMakefile (po_repo): Set a new URL for PO file updates.
2645 (get-config/config.guess get-config/config.sub): Get these files
2646 from the Savannah config project instead of ftp.gnu.org.
2648 2003-10-05 Paul Eggert <eggert@twinsun.com>
2650 * main.c (main): Avoid potential subscript error if environ has
2651 short strings.
2653 2003-08-22 Paul D. Smith <psmith@gnu.org>
2655 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2656 systems which don't yet implement the C89 standard :-/.
2658 2003-07-18 Paul D. Smith <psmith@gnu.org>
2660 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2661 [WINDOWS32]: Initialize hash.
2663 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2665 * dir.c (read_dirstream): Provide a workaround for broken versions of
2666 the MinGW dirent structure.
2668 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2670 * w32/include/dirent.h: Add __MINGW32__ filter.
2672 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2674 * make.h: Add global declaration of *make_host.
2675 * main.c (print_usage): Remove local declaration of *make_host.
2676 (print_version): Display "This program built for ..." after Copyright
2677 notice.
2679 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2681 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2682 execution of "makeinfo --html make.texi".
2684 2003-04-30 Paul D. Smith <psmith@gnu.org>
2686 * build.template: Make some changes to maybe allow this script to
2687 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2689 * README.OS2.template: New file for OS/2 support. Original
2690 contributed by Andreas Buening.
2691 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2692 DOS-style paths.
2694 2003-04-19 Paul D. Smith <psmith@gnu.org>
2696 Fix bug #1405: allow a target to match multiple pattern-specific
2697 variables.
2699 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2700 variable.c, where they've always belonged.
2701 * rule.h: Move the prototypes and struct pattern_var as well.
2702 * variable.c (initialize_file_variables): Invoke
2703 lookup_pattern_var() in a loop, until no more matches are found.
2704 If a match is found, create a new variable set for the target's
2705 pattern variables. Then merge the contents of each matching
2706 pattern variable set into the target's pattern variable set.
2707 (lookup_pattern_var): Change this function to be usable
2708 in a loop. It takes a starting position: if NULL, start at the
2709 beginning; if non-NULL, start with the pattern variable after that
2710 position, and return the next matching pattern.
2711 (create_pattern_var): Create a unique instance of
2712 pattern-specific variables for every definition in the makefile.
2713 Don't combine the same pattern together. This allows us to
2714 process the variable handling properly even when the same pattern
2715 is used multiple times.
2716 (parse_variable_definition): New function: break out the parsing
2717 of a variable definition line from try_variable_definition.
2718 (try_variable_definition): Call parse_variable_definition to
2719 parse.
2720 (print_variable_data_base): Print out pattern-specific variables.
2721 * variable.h (struct variable): Remember when a variable is
2722 conditional. Also remember its flavor.
2723 (struct pattern_var): Instead of keeping a variable set, we just
2724 keep a single variable for each pattern.
2725 * read.c (record_target_var): Each pattern variable contains only a
2726 single variable, not a set, so create it properly.
2727 * doc/make.texi (Pattern-specific): Document the new behavior.
2729 2003-04-17 Paul D. Smith <psmith@gnu.org>
2731 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2732 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2733 file/directory naming rules for VMS so I can't tell whether this
2734 is correct or not.
2736 2003-04-09 Paul D. Smith <psmith@gnu.org>
2738 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2739 DOS-style pathnames: backslash separators and drive specifiers.
2741 2003-03-28 Paul D. Smith <psmith@gnu.org>
2743 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2744 the intermediate flag on all targets. Fixes bug #2515.
2746 2003-03-24 Paul D. Smith <psmith@gnu.org>
2748 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2749 Upgrade to autoconf 2.57 and automake 1.7.3.
2751 * job.c: More OS/2 changes from Andreas Buening.
2753 * file.c (print_file): Fix variable initialization.
2754 Fixes bug #2892.
2756 * remake.c (notice_finished_file):
2758 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2759 some calls (like readdir()) return NULL in valid situations
2760 without resetting errno. Fixes bug #2846.
2762 2003-02-25 Paul D. Smith <psmith@gnu.org>
2764 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2766 * job.c (_is_unixy_shell) [OS/2]: New function.
2767 Set default shell to /bin/sh.
2768 (reap_children): Close the job_rfd pipe here since we don't use a
2769 SIGCHLD handler.
2770 (set_child_handler_action_flags): define this to empty on OS/2.
2771 (start_job_command): Close the jobserver pipe and use
2772 child_execute_job() instead of fork/exec.
2773 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2774 rather than exec'ing, then reconfigure stdin/stdout.
2775 (exec_command): Rewrite to use spawn instead of exec. Return the
2776 PID of the child.
2778 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2779 in DOS. Handle the TEMP environment variable as in DOS. Don't
2780 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2781 use -j in DOS mode. Use child_execute_job() instead of
2782 exec_command().
2784 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2785 spawn() instead.
2787 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2788 prototypes that return values.
2790 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2792 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2793 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2794 for OS/2.
2795 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2796 DOS paths.
2798 2003-02-24 Paul D. Smith <psmith@gnu.org>
2800 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2801 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2802 (child_execute_job) [VMS]: Handle error status properly.
2803 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2805 * function.c (func_shell): Use EINTRLOOP() while reading from the
2806 subshell pipe (Fixes bug #2502).
2807 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2808 jobserver pipe.
2809 * main.c (main): Ditto.
2811 2003-01-30 Paul D. Smith <psmith@gnu.org>
2813 * read.c (eval): eval() was not fully reentrant, because the
2814 collapsed buffer was static. Change it to be an automatic
2815 variable so that eval() can be invoked recursively.
2816 Fixes bug # 2238.
2817 (eval): Apply patch # 1022: fix memory reference error on long
2818 target-specific variable lines.
2819 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2821 * function.c (check_numeric): Combine the is_numeric() function
2822 into this function, since it's only called from one place.
2823 Constify this function. Have it print the incorrect string in the
2824 error message. Fixes bug #2407.
2825 (strip_whitespace): Constify.
2826 (func_if): Constify.
2827 * expand.c (expand_argument): Constify.
2829 2003-01-29 Paul D. Smith <psmith@gnu.org>
2831 Fix bug # 2169, also reported by other people on various systems.
2833 * make.h: Some systems, such as Solaris and PTX, do not fully
2834 implement POSIX-compliant SA_RESTART functionality; important
2835 system calls like stat() and readdir() can still fail with EINTR
2836 even if SA_RESTART has been set on the signal handler. So,
2837 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2838 EINTR for system calls which return -1 or 0 (NULL), respectively,
2839 on error.
2840 Also, remove the old atomic_stat()/atomic_readdir() and
2841 HAVE_BROKEN_RESTART handling.
2843 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2845 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2846 * remake.c (touch_file): Ditto.
2848 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2849 * read.c (construct_include_path): Ditto.
2850 * remake.c (name_mtime): Ditto.
2851 * vpath.c (selective_vpath_search): Ditto.
2852 * dir.c (find_directory): Ditto.
2853 (local_stat): Ditto.
2854 (find_directory): Use ENULLLOOP() to wrap opendir().
2855 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2857 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2858 atomic_readdir() handling.
2860 2003-01-22 Paul D. Smith <psmith@gnu.org>
2862 * function.c (func_call): Fix Bug #1744. If we're inside a
2863 recursive invocation of $(call ...), mask any of the outer
2864 invocation's arguments that aren't used by this one, so that this
2865 invocation doesn't "inherit" them accidentally.
2867 2002-12-05 Paul D. Smith <psmith@gnu.org>
2869 * function.c (subst_expand): Valery Khamenia reported a
2870 pathological performance hit when doing substitutions on very
2871 large values with lots of words: turns out we were invoking
2872 strlen() a ridiculous number of times. Instead of having each
2873 call to sindex() call strlen() again, keep track of how much of
2874 the text we've seen and pass the length to sindex().
2876 2002-11-19 Paul D. Smith <psmith@gnu.org>
2878 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2881 2002-11-16 Paul D. Smith <psmith@gnu.org>
2883 * NMakefile.template (OBJS): Add hash.c object file.
2884 * SMakefile.template (srcs): Ditto.
2885 * Makefile.ami (objs): Ditto.
2886 * build_w32.bat: Ditto.
2888 * Makefile.DOS.template: Remove extra dependencies.
2890 2002-10-25 Paul D. Smith <psmith@gnu.org>
2892 * expand.c (install_variable_buffer): New function. Install a new
2893 variable_buffer context and return the previous one.
2894 (restore_variable_buffer): New function. Free the current
2895 variable_buffer context and put a previously saved one back.
2896 * variable.h: Prototypes for {install,restore}_variable_buffer.
2897 * function.c (func_eval): Push a new variable_buffer context
2898 before we eval, then restore the old one when we're done.
2899 Fixes Bug #1517.
2901 * read.c (install_conditionals): New function. Install a new
2902 conditional context and return the previous one.
2903 (restore_conditionals): New function. Free the current
2904 conditional context and put a previously saved one back.
2905 (eval): Use the {install,restore}_conditionals for "include"
2906 handling.
2907 (eval_buffer): Use {install,restore}_conditionals to preserve the
2908 present conditional state before we evaluate the buffer.
2909 Fixes Bug #1516.
2911 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2912 and $(value ...).
2913 (Recursion): Add a variable index entry for CURDIR.
2915 * README.cvs: Update to appropriate versions.
2916 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2917 don't need to copy loadavg.c: automake is smart enough to create
2918 it for me. Still have a bug in automake related to ansi2knr tho.
2920 2002-10-14 Paul D. Smith <psmith@gnu.org>
2922 * remake.c (notice_finished_file): Only touch targets if they have
2923 at least one command (as per POSIX). Resolve Bug #1418.
2925 * *.c: Convert to using ANSI C-style function definitions.
2926 * Makefile.am: Enable the ansi2knr feature of automake.
2927 * configure.in: ditto.
2929 2002-10-13 Paul D. Smith <psmith@gnu.org>
2931 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2932 for automatic variable values like $^, etc. In the case of very
2933 large lists of prerequisites this causes problems. Instead reuse
2934 a static buffer (resizeable) for each variable.
2936 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2937 target-specific variable definitions. Check for it and set an
2938 "exported" flag.
2939 (record_target_var): Set the export field to v_export if the
2940 "exported" flag is set.
2941 * doc/make.texi (Target-specific): Document the ability to use
2942 "export".
2944 * doc/make.texi: Change the name of the section on automatic
2945 variables from "Automatic" to "Automatic Variables". Added text
2946 clarifying the scope of automatic variables.
2948 2002-10-04 Paul D. Smith <psmith@gnu.org>
2950 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2951 as () braces.
2952 (record_files): Ditto.
2954 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2955 the search for the '=' to only within the enclosing parens.
2957 2002-10-03 Paul D. Smith <psmith@gnu.org>
2959 Version 3.80 released.
2961 * dir.c: Change hash functions to use K&R function definition style.
2962 * function.c: Ditto.
2963 * read.c: Ditto.
2964 * variable.c: Ditto.
2966 Update to automake 1.7.
2968 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2969 (pdf): Remove this target as automake now provides one.
2971 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2973 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2975 * makefile.com: Updates for GNU make 3.80.
2976 * makefile.vms: Ditto.
2978 2002-09-23 Paul D. Smith <psmith@gnu.org>
2980 * read.c (enum make_word_type): Remove w_comment.
2981 (get_next_mword): Don't treat comment characters as special; where
2982 this function is used we will never see a comment (it's stripped
2983 before we get here) and treating comments specially means that
2984 targets like "foo\#bar" aren't handled properly.
2986 2002-09-18 Paul D. Smith <psmith@gnu.org>
2988 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2990 * read.c (eval): Expansion of arguments to export/unexport was
2991 ignoring all arguments after the first one. Change the algorithm
2992 to expand the whole line once, then parse the results.
2994 2002-09-17 Paul D. Smith <psmith@gnu.org>
2996 Fix Bug #940 (plus another bug I found while looking at this):
2998 * read.c (record_target_var): enter_file() will add a new entry if
2999 it's a double-colon target: we don't want to do that in this
3000 situation. Invoke lookup_file() and only enter_file() if it does
3001 not already exist. If the file we get back is a double-colon then
3002 add this variable to the "root" double-colon target.
3004 * variable.c (initialize_file_variables): If this file is a
3005 double-colon target but is not the "root" target, then initialize
3006 the root and make the root's variable list the parent of our
3007 variable list.
3009 2002-09-13 Paul D. Smith <psmith@gnu.org>
3011 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3013 * hash.c (round_up_2): Get rid of a warning.
3015 2002-09-12 Paul D. Smith <psmith@gnu.org>
3017 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3018 so it doesn't complain about getloadavg.c.
3020 * commands.c (set_file_variables): Make sure we always alloca() at
3021 least 1 character for the value of $? (for '\0').
3023 2002-09-11 Paul D. Smith <psmith@gnu.org>
3025 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3026 macro to use RESULT instead of the incorrect _RESULT_.
3028 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3029 and atomic_readdir(). We need to #include dirent.h to get this to
3030 work.
3031 * misc.c (atomic_readdir): Fix typos.
3033 2002-09-10 Paul D. Smith <psmith@gnu.org>
3035 * read.c (eval): Expand variable lists given to export and
3036 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3037 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3039 * doc/make.texi (Variables/Recursion): Document this.
3040 (Conditional Syntax): And here.
3042 2002-09-09 Paul D. Smith <psmith@gnu.org>
3044 * configure.in: Check for memmove().
3046 2002-09-07 Paul D. Smith <psmith@gnu.org>
3048 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3049 Michael Sterrett <msterret@coat.com> reports that while it has
3050 SA_RESTART, it does not work properly.
3052 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3053 that invokes stat() and loops to do it again if it returns EINTR.
3054 (atomic_readdir): Ditto, with readdir().
3056 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3057 and readdir() to atomic_stat() and atomic_readdir().
3059 2002-09-04 Paul D. Smith <psmith@gnu.org>
3061 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3062 reports that GNU make sometimes doesn't recognize that targets can
3063 be made, when directories can be created as prerequisites. He
3064 reports that changing the order of predicates in the DEP->changed
3065 flag test so that lookup_file() is always performed, solves this
3066 problem.
3068 2002-08-08 Paul D. Smith <psmith@gnu.org>
3070 * configure.in: Require a newer version of gettext.
3072 * misc.c (perror_with_name): Translate the format string (for
3073 right-to-left language support).
3074 (pfatal_with_name): Ditto.
3076 * main.c: Create a static array of strings to store the usage
3077 text. This is done to facilitate translations.
3078 (struct command_switch): Remove argdesc and description fields.
3079 (switches): Remove values for obsolete fields.
3080 (print_usage): Print each element of the usage array.
3082 * hash.c: Change function definitions to be K&R style.
3084 2002-08-02 Paul D. Smith <psmith@gnu.org>
3086 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3087 this one because it's too hard to get right. We'll look at it for
3088 a future release.
3089 * main.c (main): Don't create the .TARGETS variable.
3090 * variable.c (handle_special_var): Don't handle .TARGETS.
3092 2002-08-01 Paul D. Smith <psmith@gnu.org>
3094 * main.c (switches): Add a new option, -B (--always-make). If
3095 specified, make will rebuild all targets that it encounters even
3096 if they don't appear to be out of date.
3097 (always_make_flag): New flag.
3098 * make.h: Extern always_make_flag.
3099 * remake.c (update_file_1): Check always_make_flag; if it's set we
3100 will always rebuild any target we can, even if none of its
3101 prerequisites are newer.
3102 * NEWS: Mention it.
3104 * doc/make.texi (Shell Function): Make it clear that make
3105 variables marked as "export" are not passed to instances of the
3106 shell function.
3108 Add new introspection variable .VARIABLES and .TARGETS.
3110 * variable.c (handle_special_var): New function. If the variable
3111 reference passed in is "special" (.VARIABLES or .TARGETS),
3112 calculate the new value if necessary. .VARIABLES is handled here:
3113 walk through the hash of defined variables and construct a value
3114 which is a list of the names. .TARGETS is handled by
3115 build_target_list().
3116 (lookup_variable): Invoke handle_special_var().
3117 * file.c (build_target_list): Walk through the hask of known files
3118 and construct a list of the names of all the ones marked as
3119 targets.
3120 * main.c (main): Initialize them to empty (and as simple variables).
3121 * doc/make.texi (Special Variables): Document them.
3122 * NEWS: Mention them.
3124 * variable.h (struct variable): Add a new flag "exportable" which
3125 is true if the variable name is valid for export.
3126 * variable.c (define_variable_in_set): Set "exportable" when a new
3127 variable is defined.
3128 (target_environment): Use the "exportable" flag instead of
3129 re-checking the name here... an efficiency improvement.
3131 2002-07-31 Paul D. Smith <psmith@gnu.org>
3133 * config.h-vms.template: Updates to build on VMS. Thanks to
3134 Brian_Benning@aksteel.com for helping verify the build.
3135 * makefile.com: Build the new hash.c file.
3136 * hash.h: Use strcpmi(), not stricmp(), in the
3137 HAVE_CASE_INSENSITIVE_FS case.
3139 2002-07-30 Paul D. Smith <psmith@gnu.org>
3141 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3142 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3143 Reported by <Brian_Benning@aksteel.com>.
3145 2002-07-10 Paul D. Smith <psmith@gnu.org>
3147 * variable.c (pop_variable_scope): Remove variable made unused by
3148 new hash infrastructure.
3149 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3150 comparisons as well as name comparisons.
3151 * variable.h: Add a prototype for new hash_init_function_table().
3152 * file.c (lookup_file): Remove variables made unused by new hash
3153 infrastructure.
3154 * dir.c (directory_contents_hash_2): Missing return of hash value.
3155 (dir_contents_file_exists_p): Remove variables made unused by new
3156 hash infrastructure.
3159 Installed Greg McGary's integration of the hash functions from the
3160 GNU id-utils package:
3162 2002-07-10 Greg McGary <greg@mcgary.org>
3164 * scripts/functions/filter-out: Add literals to to the
3165 pattern space in order to add complexity, and trigger
3166 use of an internal hash table. Fix documentation strings.
3167 * scripts/targets/INTERMEDIATE: Reverse order of files
3168 passed to expected `rm' command.
3170 2002-07-10 Greg McGary <greg@mcgary.org>
3172 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3173 * hash.c: New file, taken from id-utils.
3174 * hash.h: New file, taken from id-utils.

3184 (init_hash_files): New function decl.
3186 * ar.c (ar_name): Delay call to strlen until needed.
3187 * main.c (initialize_global_hash_tables): New function.
3188 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3189 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3190 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
3192 * dir.c (hash.h): New #include.
3193 (struct directory_contents) [next, files]: Remove members.
3194 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

3204 (find_directory): Use new hash table package.
3205 (dir_contents_file_exists_p): Likewise.
3206 (file_impossible): Likewise.
3207 (file_impossible_p): Likewise.
3208 (print_dir_data_base): Likewise.
3209 (open_dirstream): Likewise.
3210 (read_dirstream): Likewise.
3211 (hash_init_directories): New function.
3213 * file.c (hash.h): New #include.
3214 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
3215 (files): Change type to `struct hash_table'.
3216 (lookup_file): Use new hash table package.
3217 (enter_file): Likewise.
3218 (remove_intermediates): Likewise.
3219 (snap_deps): Likewise.
3220 (print_file_data_base): Likewise.
3222 * function.c
3223 (function_table_entry_hash_1, function_table_entry_hash_2,
3224 function_table_entry_hash_cmp): New functions.
3225 (lookup_function): Remove `table' argument.
3226 Use new hash table package.
3227 (struct a_word) [chain, length]: New members.
3228 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3229 (struct a_pattern): New struct.
3230 (func_filter_filterout): Pass through patterns noting boundaries
3231 and '%', if present. Note a_word length. Use a hash table if
3232 arglists are large enough to justify cost.
3233 (function_table_init): Renamed from function_table.
3234 (function_table): Declare as `struct hash_table'.
3235 (FUNCTION_TABLE_ENTRIES): New constant.
3236 (hash_init_function_table): New function.
3238 * read.c (hash.h): New #include.
3239 (read_makefile): Pass char constants to find_char_unquote.
3240 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3241 (uniquize_deps): Use hash table to efficiently identify duplicates.
3242 (find_char_unquote): Accept two char-constant stop chars, rather
3243 than a string constant, avoiding zillions of calls to strchr.
3244 Tighten inner search loops to test only for desired delimiters.
3246 * variable.c (variable_hash_1, variable_hash_2,
3247 variable_hash_cmp): New functions.
3248 (variable_table): Declare as `struct hash_table'.
3249 (global_variable_set): Remove initialization.

3259 (target_environment): Likewise.
3260 (print_variable_set): Likewise.
3262 2002-07-10 Paul D. Smith <psmith@gnu.org>
3264 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3265 prerequisite list. A real SysV make will expand the entire
3266 prerequisites list _twice_: we don't do that as it's a big
3267 backward-compatibility problem. We only replace those specific
3268 variables.
3270 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3271 references left in the list of prerequisites. Check for .POSIX as
3272 we record targets, so we can disable non-POSIX behavior while
3273 reading makefiles as well as running them.
3274 (eval): Check the prerequisite list to see if we have anything
3275 that looks like a SysV prerequisite variable reference.
3277 2002-07-09 Paul D. Smith <psmith@gnu.org>
3279 * doc/make.texi (Prerequisite Types): Add a new section describing
3280 order-only prerequisites.
3282 * read.c (uniquize_deps): If we have the same file as both a
3283 normal and order-only prereq, get rid of the order-only prereq,
3284 since the normal one supersedes it.
3286 2002-07-08 Paul D. Smith <psmith@gnu.org>
3288 * AUTHORS: Added Greg McGary to the AUTHORS file.
3289 * NEWS: Blurbed order-only prerequisites.
3290 * file.c (print_file): Show order-only deps properly when printing
3291 the database.
3293 * maintMakefile: Add "update" targets for wget'ing the latest
3294 versions of various external files. Taken from Makefile.maint in
3295 autoconf, etc.
3297 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3298 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3300 2002-07-07 Paul D. Smith <psmith@gnu.org>
3302 * po/*.po: Remove. We'll use wget to retrieve them at release
3303 time.
3305 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3306 rather than a shell you get an exception. Make sure we look up
3307 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3309 * remake.c (notice_finished_file): Fix handling of -t flag.
3310 Patch provided by Henning Makholm <henning@makholm.net>.
3312 * implicit.c (pattern_search): Some systems apparently run short
3313 of stack space, and using alloca() in this function caused an
3314 overrun. I modified it to use xmalloc() on the two variables
3315 which seemed like they might get large. Fixes Bug #476.
3317 * main.c (print_version): Update copyright notice to conform with
3318 GNU standards.
3319 (print_usage): Update help output.
3321 * function.c (func_eval): Create a new make function, $(eval
3322 ...). Expand the arguments, put them into a buffer, then invoke
3323 eval_buffer() on the resulting string.
3324 (func_quote): Create a new function, $(quote VARNAME). Inserts
3325 the value of the variable VARNAME without expanding it any
3326 further.
3328 * read.c (struct ebuffer): Change the linebuffer structure to an
3329 "eval buffer", which can be either a file or a buffer.
3330 (eval_makefile): Move the code in the old read_makefile() which
3331 located a makefile into here: create a struct ebuffer with that
3332 information. Have it invoke the new function eval() with that
3333 ebuffer.
3334 (eval_buffer): Create a new function that creates a struct ebuffer
3335 that holds a string buffer instead of a file. Have it invoke
3336 eval() with that ebuffer.
3337 (eval): New function that contains the guts of the old
3338 read_makefile() function: this function parses makefiles. Obtains
3339 data to parse from the provided ebuffer. Some modifications to
3340 make the flow of the function cleaner and clearer. Still could
3341 use some work here...
3342 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3343 contents of the define/endef variable from the ebuffer.
3344 (readstring): Read the next line from a string-style ebuffer.
3345 (readline): Read the next line from an ebuffer. If it's a string
3346 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3347 from the file.
3349 * dep.h (eval_buffer): Prototype eval_buffer();
3351 * variable.c (do_variable_definition): Make sure that all
3352 non-target-specific variables are registered in the global set.
3353 If we're invoked from an $(eval ...) we might be inside a $(call
3354 ...) or other function which has pushed a variable scope; we still
3355 want to define our variables from evaluated makefile code in the
3356 global scope.
3358 2002-07-03 Greg McGary <greg@mcgary.org>
3360 * dep.h (struct dep) [ignore_mtime]: New member.
3361 [changed]: convert to a bitfield.
3362 * implicit.c (pattern_search): Zero ignore_mtime.
3363 * main.c (main, handle_non_switch_argument): Likewise.
3364 * rule.c (convert_suffix_rule): Likewise.
3365 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3366 (read_makefile): Parse '|' in prerequisite list.
3367 (uniquize_deps): Consider ignore_mtime when comparing deps.
3368 * remake.c (update_file_1, check_dep): Don't force remake for
3369 dependencies that have d->ignore_mtime.
3370 * commands.c (FILE_LIST_SEPARATOR): New constant.
3371 (set_file_variables): Don't include a
3372 prerequisite in $+, $^ or $? if d->ignore_mtime.
3373 Define $|.
3375 2002-06-18 Paul D. Smith <psmith@gnu.org>
3377 * make.texinfo: Updates for next revision. New date/rev/etc.
3378 Recreate all Info menus. Change license on the manual to the GNU
3379 Free Documentation License. A number of typos.
3380 (Variables Simplify): Don't use "-" before it's defined.
3381 (Automatic Prerequisites): Rewrite the target example to work
3382 properly if the compile fails. Remove incorrect comments about
3383 how "set -e" behaves.
3384 (Text Functions): Move the "word", "wordlist", "words", and
3385 "firstword" functions here, from "File Name Functions".
3386 * make-stds.texi: Update from latest GNU version.
3387 * fdl.texi: (created) Import the latest GNU version.
3389 2002-06-06 Paul D. Smith <psmith@gnu.org>
3391 * variable.c (do_variable_definition): New function: extract the
3392 part of try_variable_definition() that actually sets the value
3393 into a separate function.
3394 (try_variable_definition): Call do_variable_definition() after
3395 parsing the variable definition string.
3396 (define_variable_in_set): Make the name argument const.
3398 * variable.h (enum variable_flavor): Make public.
3399 (do_variable_definition): Create prototype.
3401 * read.c (read_all_makefiles): Create a new built-in variable,
3402 MAKEFILE_LIST.
3403 (read_makefile): Add each makefile read in to this variable value.
3405 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3407 * Makefile.DOS.template: Tweak according to changes in the
3408 distribution. Add back the dependencies of *.o files.
3410 * configh.dos.template: Synchronize with config.h.in.
3412 2002-05-09 Paul D. Smith <psmith@gnu.org>
3414 * file.c (file_timestamp_now): Use K&R function declaration.
3416 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3417 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3418 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3419 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3420 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3421 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3422 nlist.n_name is a pointer rather than an array.
3424 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3425 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3426 * configure.in: Use it instead of the old version.
3428 * main.c (main): Prefer setvbuf() to setlinebuf().
3430 2002-05-08 Paul D. Smith <psmith@gnu.org>
3432 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3433 (loadavg_LDADD): Ditto.
3435 2002-04-29 Paul D. Smith <psmith@gnu.org>
3437 * expand.c (recursively_expand_for_file): Rename
3438 recursively_expand() to recursively_expand_for_file() and provide
3439 an extra argument, struct file. If the argument is provided, set
3440 the variable scope to that of the file before expanding.
3441 * variable.h (recursively_expand): Make this a macro that invokes
3442 recursively_expand_for_file() with a NULL file pointer.
3443 * variable.c (target_environment): Call the renamed function and
3444 provide the current file context.
3445 Fixes Debian bug #144306.
3447 2002-04-28 Paul D. Smith <psmith@gnu.org>
3449 Allow $(call ...) user-defined variables to be self-referencing
3450 without throwing an error. Allows implementation of transitive
3451 closures, among other possibly useful things.
3452 Requested by: Philip Guenther <guenther@sendmail.com>
3454 * variable.h (struct variable): Add a new field: exp_count, and
3455 new macros to hold its size and maximum value.
3456 (warn_undefined): Make this a macro.
3457 * variable.c (define_variable_in_set): Initialize it.
3458 * expand.c (recursively_expand): If we detect recursive expansion
3459 of a variable, check the exp_count field. If it's greater than 0
3460 allow the recursion and decrement the count.
3461 (warn_undefined): Remove this (now a macro in variable.h).
3462 * function.c (func_call): Before we expand the user-defined
3463 function, modify its exp_count field to contain the maximum
3464 number of recursive calls we'll allow. After the call, reset it
3465 to 0.
3467 2002-04-21 Paul D. Smith <psmith@gnu.org>
3469 Modified to use latest autoconf (2.53), automake (1.6.1), and
3470 gettext (0.11.1). We're using gettext's new "external" support,
3471 to avoid including libintl source with GNU make.
3473 * README.cvs: New file. Explain how to build GNU make from CVS.
3475 * configure.in: Modify checking for the system glob library.
3476 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3477 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3478 etc. will manage it correctly). Set an automake conditional
3479 USE_LOCAL_GLOB to decide whether to compile the glob library.
3481 * getloadavg.c (main): Include make.h in the "TEST" program to
3482 avoid warnings.
3484 * Makefile.am: Remove special rules for loadavg. Replace them
3485 with Automake capabilities for building extra programs.
3487 * signame.c: This file does nothing if the system provide
3488 strsignal(). If not, it implements strsignal(). If the system
3489 doesn't define sys_siglist, then we make our own; otherwise we use
3490 the system version.
3491 * signame.h: Removed.
3493 * main.c (main): No need to invoke signame_init(). Update copyright.
3495 * ABOUT-NLS: Removed.
3496 * gettext.c: Removed.
3497 * gettext.h: Get a simplified copy from the gettext package.
3498 * po/*: Created.
3499 * i18n/*.po: Moved to po/.
3500 * i18n/: Removed.
3502 * config/*: Created. Contains package configuration helper files.
3503 * config.guess, config.sub: Moved to config directory.
3505 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3506 Rework to use new-style autoconf features. Use the "external"
3507 mode for gettext. Make the build.sh config file conditional on
3508 whether build.sh.in exists, to avoid autoconf errors.
3509 * acinclude.m4: Removed almost all macros as being obsolete.
3510 Rewrote remaining macros to use AC_DEFINE.
3511 * acconfig.h: Removed.
3513 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3514 conditional to handle customs support. Remove special handling
3515 for i18n features.
3517 2002-04-20 Paul D. Smith <psmith@gnu.org>
3519 * function.c (func_call): Don't mark the argument variables $1,
3520 etc. as recursive. They've already been fully expanded so
3521 there's no need to do it again, and doing so strips escaped $'s.
3522 Reported by Sebastian Glita <glseba@yahoo.com>.
3524 * remake.c (notice_finished_file): Walk through double-colon
3525 entries via the prev field, not the next field!
3526 Reported by Greg McGary <greg@mcgary.org>.
3528 * main.c (main): If the user specifies -q and asks for a specific
3529 target which is a makefile, we got an assert. In that case it
3530 turns out we should continue normally instead.
3532 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3534 * i18n/he.po: Installed a new translation.
3536 2002-01-07 Paul D. Smith <psmith@gnu.org>
3538 * i18n/es.po, i18n/ru.po: Installed an updated translation.

3544 2001-09-06 Paul Eggert <eggert@twinsun.com>
3546 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3547 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3549 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3550 are available.
3551 (main): Get rid of any avoidable limit on stack size.
3553 2001-09-04 Paul D. Smith <psmith@gnu.org>

3557 2001-08-03 Paul D. Smith <psmith@gnu.org>
3559 * i18n/fr.po: Installed an updated translation.
3560 Resolves Debian bug #106720.
3562 2001-06-13 Paul D. Smith <psmith@gnu.org>
3564 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3565 translation.
3567 2001-06-11 Paul D. Smith <psmith@gnu.org>
3569 * i18n/ko.po: Installed a new translation.
3571 2001-05-06 Paul D. Smith <psmith@gnu.org>
3573 Modify the EINTR handling.
3575 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3576 the way in which we manage the file descriptor/signal handler race
3577 trap to be more efficient.
3579 2001-05-06 Paul Eggert <eggert@twinsun.com>
3581 Restart almost all system calls that are interrupted, instead
3582 of worrying about EINTR. The lone exception is the read() for
3583 job tokens.
3585 * configure.in (HAVE_SA_RESTART): New macro.
3586 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3587 * main.c (main): Use SA_RESTART instead of the old,
3588 nonstandard SA_INTERRUPT.
3590 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3591 * main.c (bsd_signal): New function or macro,
3592 if the implementation doesn't supply it.
3593 (The bsd_signal function will be in POSIX 1003.1-200x.)
3594 (HANDLESIG): Remove.
3595 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3597 * make.h (EINTR_SET): Remove.
3598 (SA_RESTART): New macro.
3600 * arscan.c (ar_member_touch): Don't worry about EINTR.
3601 * function.c (func_shell): Likewise.
3602 * job.c (reap_children, free_child, new_job): Likewise.
3603 * main.c (main): Likewise.
3604 * remake.c (touch_file, name_mtime): Likewise.
3606 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3607 if fstat failed with errno!=EINTR, the error was ignored.
3609 * job.c (set_child_handler_action_flags): New function.
3610 (new_job): Use it to temporarily clear the SIGCHLD action flags
3611 while reading the token.
3613 2001-05-02 Paul D. Smith <psmith@gnu.org>
3615 * job.c (start_job_command): Don't add define/endef per-line flags
3616 to the top-level flags setting.
3618 2001-04-03 Paul D. Smith <psmith@gnu.org>
3620 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3621 bit on error, so check for odd return values, not non-0 return
3622 values.
3623 (VMS_get_member_info): Calculate the timezone differences correctly.
3624 Reported by John Fowler <jfowler@nyx.net>.
3627 2001-03-14 Paul D. Smith <psmith@gnu.org>
3629 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3630 value before invoking define_variable().
3631 Reported by John Fowler <jfowler@nyx.net>.
3633 2001-02-07 Paul D. Smith <psmith@gnu.org>
3635 * read.c (record_target_var): If we reset the variable due to a
3636 command-line variable setting overriding it, turn off the "append"
3637 flag.
3639 2001-01-17 Paul D. Smith <psmith@gnu.org>
3641 * variable.c (lookup_variable) [VMS]: When getting values from the
3642 environment, allocate enough space for the _value_ plus escapes,
3643 not enough space for the name plus escapes :-/.
3644 Reported by John Fowler <jfowler@nyx.net>.
3646 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3647 warnings that make generates, so it doesn't look like an error.
3648 Reported by Karl Berry <karl@gnu.org>.
3651 Fix for PR/2020: Rework appended target-specific variables. I'm
3652 fairly confident this algorithm is finally correct.
3654 * expand.c (allocated_variable_append): Rewrite. Instead of
3655 expanding each appended variable then adding all the expanded
3656 strings together, we append all the unexpanded values going up
3657 through the variable set contexts, then expand the final result.
3658 This behaves just like non-target-specific appended variable
3659 values, while the old way didn't in various corner cases.
3660 (variable_append): New function: recursively append the unexpanded
3661 value of a variable, walking from the outermost variable scope to
3662 the innermost.
3663 * variable.c (lookup_variable): Remove the code that looked up the
3664 variable set list if the found variable was "append". We don't
3665 need this anymore.
3666 (lookup_variable_in_set): Make this non-static so we can use it
3667 elsewhere.
3668 (try_variable_definition): Use lookup_variable_in_set() rather
3669 than faking out current_variable_set_list by hand (cleanup).
3670 * variable.h: Add a prototype for the now non-static
3671 lookup_variable_in_set().
3673 2000-11-17 Paul D. Smith <psmith@gnu.org>
3675 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3676 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3677 before throwing a fit.
3679 2000-11-17 Paul D. Smith <psmith@gnu.org>
3681 * read.c (readline): CRLF calculations had a hole, if you hit the
3682 buffer grow scenario just right. Reworked the algorithm to avoid
3683 the need for len or lastlen at all. Problem description with
3684 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3686 2000-10-24 Paul D. Smith <psmith@gnu.org>
3688 * gettext.c (SWAP): Declare this with the prototype, otherwise
3689 some systems don't work (non-32-bit? Reported for Cray T3E).
3690 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3692 2000-10-05 Paul D. Smith <psmith@gnu.org>
3694 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3695 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3697 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3699 2000-09-22 Paul D. Smith <psmith@gnu.org>
3701 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3702 parts of the real gettext.h here, and we expect to really include
3703 the real gettext.h later. If we keep this #define, it's ignored.
3705 2000-09-21 Paul D. Smith <psmith@gnu.org>
3707 * main.c (log_working_directory): Rework the text to use complete
3708 sentences, to make life simpler for the translators.
3710 2000-08-29 Paul D. Smith <psmith@gnu.org>
3712 * file.c (remove_intermediates): Print a debug message before we
3713 remove intermediate files, so the user (if she uses -d) knows
3714 what's going on.
3716 2000-08-21 Paul D. Smith <psmith@gnu.org>
3718 * variable.c (try_variable_definition): Change how we handle
3719 target-specific append variable defns: instead of just setting the
3720 value, expand it as an append _but_ only within the current
3721 target's context. Otherwise we lose all but the last value if the
3722 variable is appended more than once within the current target
3723 context. Fixes PR/1831.
3725 2000-08-16 Paul D. Smith <psmith@gnu.org>
3727 * function.c (func_shell): Nul-terminate the buffer before
3728 printing an exec error message (just in case it's not!).
3729 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3731 2000-07-25 Paul D. Smith <psmith@gnu.org>
3733 * job.c (construct_command_argv_internal): Add "~" to the list of
3734 sh_chars[] which disallow optimizing out the shell call.
3736 2000-07-23 Paul Eggert <eggert@twinsun.com>
3738 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3739 supersedes --disable-nsec-timestamps.
3740 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3741 * README: Remove --disable-nsec-timestamps.
3743 * filedef.h (struct file.low_resolution_time): New member.
3744 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3745 * remake.c (update_file_1):
3746 Avoid spurious rebuilds due to low resolution time stamps,
3747 generalizing the earlier code that applied only to archive members.
3748 (f_mtime): Archive members always have low resolution time stamps.
3750 * configure.in: Remove --disable-nsec-timestamps, as this has
3751 been superseded by .LOW_RESOLUTION_TIME.
3753 2000-07-23 Paul Eggert <eggert@twinsun.com>
3755 * configure.in (enable_nsec_timestamps): Renamed from
3756 make_cv_nsec_timestamps, since enable/disable options
3757 shouldn't be cached.
3759 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3760 and Paul Eggert <eggert@twinsun.com>
3762 * file.c (file_timestamp_now):
3763 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3764 so that clock_gettime is not linked unless needed.
3766 * filedef.h (FILE_TIMESTAMP_HI_RES):
3767 Remove definition; "configure" now does this.
3769 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3770 to before high resolution file timestamp check,
3771 since that check now uses uintmax_t.
3772 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3773 high resolution file timestamps.
3774 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3775 so that we don't link in clock_gettime unnecessarily.
3777 2000-07-17 Paul D. Smith <psmith@gnu.org>
3779 * i18n/ja.po: New version of the translation file.
3781 2000-07-07 Paul D. Smith <psmith@gnu.org>
3783 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3784 the offset calculation.
3785 (name_mtime): Replace EINTR test with EINTR_SET macro.
3787 2000-07-07 Paul Eggert <eggert@twinsun.com>
3789 Fix for PR/1811:
3791 * remake.c (update_file_1):
3792 Avoid spurious rebuilds of archive members due to their
3793 timestamp resolution being only one second.
3794 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3795 the clock's resolution being lower than file timestamps'.
3796 When warning about future timestamps, report only the discrepancy,
3797 not the absolute value of the timestamp and the current time.
3799 * file.c (file_timestamp_now): New arg RESOLUTION.
3800 * filedef.h (file_timestamp_now): Likewise.
3801 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3803 2000-07-05 Paul D. Smith <psmith@gnu.org>
3805 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3806 to listp. Fixes PR/1793.
3808 2000-06-26 Paul Eggert <eggert@twinsun.com>
3810 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3812 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3814 * remake.c (f_mtime): Remove unused var memtime.
3816 2000-06-25 Martin Buchholz <martin@xemacs.org>
3818 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3819 Ran spell-check on make.texinfo.
3821 2000-06-23 Paul D. Smith <psmith@gnu.org>
3823 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3824 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3825 * make.h: Define these macros.
3827 * Version 3.79.1 released.
3829 * configure.in: Add a new option, --disable-nsec-timestamps, to
3830 avoid using sub-second timestamps on systems that support it. It
3831 can lead to problems, e.g. if your makefile relies on "cp -p".
3832 * README.template: Document the issue with "cp -p".
3834 * config.guess, config.sub: Updated.
