4 * NEWS: Mention the new behavior of .POSIX and the new .SHELLFLAGS
6 * job.c (construct_command_argv): Retrieve the .SHELLFLAGS value
7 and pass it to construct_command_argv_internal().
8 (construct_command_argv_internal): If .SHELLFLAGS is non-standard
9 use the slow path. Use that value instead of hard-coded "-c".
11 2010-07-05 Paul Smith <psmith@gnu.org>
13 * implicit.c (pattern_search): lastslash can be const.
14 * dir.c (downcase): Remove unused variable.

26 2010-07-03 Paul Smith <psmith@gnu.org>
28 * read.c (parse_file_seq): All archive groups must end with ')' as
29 the LAST character in a word. If there is no word ending in ')'
30 then it's not an archive group. Fixes Savannah bug #28525.
32 2010-07-01 Paul Smith <psmith@gnu.org>
34 * main.c (main): Append optional features using separate calls.
35 Not as efficient but not all compilers allow conditionals inside
36 macro calls. Fixes Savannah bug #29244.

86 2009-11-12 Boris Kolpackov <boris@codesynthesis.com>
88 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
89 which allows the caller to get the index of the matching directory.
91 * make.h (vpath_search): Update prototype.
93 * remake.c (library_search): Implement linker-compatible library
94 search. Use the new VPATH_SEARCH index functionality to keep track
95 of the directory index for each match. Select the match with the
96 lowest directory index.
98 * implicit.c (pattern_search): Pass NULL for the index arguments in
99 the VPATH_SEARCH call.
101 * doc/make.texi (Directory Search for Link Libraries): Describe the

110 * implicit.c (stemlen_compare): Fix qsort() compare bug that
111 caused implicit rules with equal stem lengths to be sorted
114 2009-10-24 Paul Smith <psmith@gnu.org>
116 * main.c (usage): Add --eval to the usage string.
117 (switches): Add the --eval switch.
118 (main): If --eval is given, add them to the simply-expanded variable

122 * NEWS: Describe the new --eval command line argument.
123 * doc/make.texi (Options Summary): Document --eval.

129 * variable.h (define_variable_cname): New macro for constant
131 * default.c (set_default_suffixes): Use it.

149 * read.c (do_undefine): Free the expanded variable name.
151 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
152 to normal upgrade logic from dep_hash_cmp to set_file_variables.
154 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
156 * dep.h (uniquize_deps): Remove.
158 * read.c (uniquize_deps): Merge into set_file_variables in
160 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
162 * commands.c (set_file_variables): Avoid modifying the dep
163 chain to achieve uniqueness. Fixes savannah bug 25780.
165 * implicit.c (pattern_search): Instead of re-setting all automatic
166 variables for each rule we try, just update $*.
168 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
170 * variable.h (undefine_variable_in_set): New function declaration.
171 (undefine_variable_global): New macro.

186 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
188 * implicit.c (pattern_search): Initialize file variables only
189 if we need to parse a rule that requires the second expansion.
191 2009-10-03 Paul Smith <psmith@gnu.org>
193 * make.h: Include <alloca.h> even on systems where __GNUC__ is
194 defined. Not sure why it was done the other way.
195 Requested by David Boyce <dsb@boyski.com>.
197 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
199 * dep.h (dep): Add the DONTCARE bitfield.
201 * filedef.h (file):Add the NO_DIAG bitfield.
203 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
204 not struct file (a file can be a dependency of many targets,
205 some don't care, some do).
207 * remake.c (update_goal_chain): Propagate DONTCARE from struct
208 dep to struct file before updating the goal and restore it
210 (update_file): Don't prune the dependency graph if this target
211 has failed but the diagnostics hasn't been issued.
212 (complain): Scan the file's dependency graph to find the file
213 that caused the failure.
214 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
215 whether to print diagnostics.
217 Fixes Savannah bugs #15110, #25493, #12686, and #17740.

227 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
228 much of the command line on a single pass.
230 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
232 * varible.c (create_pattern_var): Insert variables into the
233 PATTERN_VARS list in the shortest patterns first order.

250 2009-09-27 Paul Smith <psmith@gnu.org>
252 * doc/make.texi (Double-Colon): Mention that pattern rules with
253 double-colons have a different meaning. Savannah bug #27497.
255 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
257 * configh.dos.template: Remove unconditional definition of
258 SYS_SIGLIST_DECLARED.
259 Include <sys/version.h> because ports of GCC 4.3.0 and later no
260 longer include it, so macros like __DJGPP_MINOR__ are no longer
261 defined automatically.
263 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
264 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
265 instead of using the hardcoded ones.
266 (SUBDIRS): doc subdir added.
267 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
268 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
269 create html formated docs. texi2html may not be ported to DOS.
270 (make.info, make.dvi, make.ps, make.html): Make targets depend on
272 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
273 -I switch to look in ./ instead of ./doc.
274 (html): Target depend on html-recursive instead of make_1.html.
275 (make_1.html): Removed.
276 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
277 (all-recursive): Allow for more than one subdir in the build
279 (mostlyclean-recursive, clean-recursive, distclean-recursive)
280 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
281 (tags-recursive): Allow for more than one subdir in the build
283 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
284 targets. Enter into doc/ to produce the targets.
285 (all-am): $(INFO_DEPS) replaced by info.
287 2009-09-26 Paul Smith <psmith@gnu.org>
289 * read.c (record_files): Use free_ns() to free struct nameseq.
292 * rule.c (freerule): Use free_dep_chain().
294 * read.c (record_files): Free FILENAMES chain for implicit rules.
295 (eval): Static pattern targets go into the string cache.
297 * function.c (string_glob): Free NAME in the nameseq chain.
299 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
301 * implicit.c (pattern_search): Terminate early if we haven't
302 found any rules to try (performance improvement).
304 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
306 * implicit.c (pattern_search): Merge three parallel arrays,
307 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
308 of struct TRYRULE. In the old version the latter two arrays
309 had insufficient length.
311 2009-09-24 Paul Smith <psmith@gnu.org>
313 * implicit.c (pattern_search): Add back support for order-only
314 prerequisites for secondary expansion implicit rules, that were
315 accidentally dropped. If we find a "|", enable order-only mode
316 and set IGNORE_MTIME on all deps that are seen afterward.
317 (pattern_search): Fix memory leaks: for intermediate files where
318 we've already set the file variable and pattern variable sets, be
319 sure to either save or free them as appropriate.
321 2009-09-23 Paul Smith <psmith@gnu.org>
323 Rework the way secondary expansion is stored, for efficiency.
324 This changes secondary expansion so that ONLY WHEN we know we have
325 a possibility of needing secondary expansion, do we defer the
326 secondary expansion. This means more parsing the deps but we use
327 a lot less memory (due to the strcache). Also, this fixes
330 * read.c (eval): Don't parse the dep string here anymore.
331 (record_files): Take the dep argument as an unparsed string. If
332 secondary expansion is enabled AND the prereq string has a '$' in
333 it, then set NEED_2ND_EXPANSION and keep the entire string.
334 Otherwise, parse the dep string here to construct the dep list
335 with the names in the strcache.
337 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
338 duplicate the name string (others are in the strcache).
340 * implicit.c: Remove struct idep and free_idep_chain(): unused.
341 (struct patdeps): New structure to store prereq information.
342 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
343 which prerequisites need expansion, and expand only those.
345 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
346 and enter_prereqs(). split_prereqs() takes a fully-expanded string
347 and splits it into a DEP list, handling order-only prereqs.
348 (enter_prereqs): This function enters a list of DEPs into the file
349 database. If there's a stem defined, expand any pattern chars.
350 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
351 set. Use the above functions.
352 (snap_deps): Only perform second expansion on prereqs that need it,
353 as defined by the NEED_2ND_EXPANSION flag.
354 (print_prereqs): New function to print the prereqs
355 (print_file): Call print_prereqs() rather than print inline.
357 * hash.h (STRING_COMPARE): Take advantage of strcache() by
359 (STRING_N_COMPARE): Ditto.
360 (ISTRING_COMPARE): Ditto.
362 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
363 (parse_file_seq): Return void*
364 * read.c (parse_file_seq): Return void*.
365 (eval): Invoke macroized version of parse_file_seq()
366 * default.c (set_default_suffixes): Ditto.
367 * file.c (split_prereqs): Ditto.
368 * function.c (string_glob): Ditto.
369 * main.c (main): Ditto.
370 * rule.c (install_pattern_rule): Ditto.
372 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
374 2009-09-16 Paul Smith <psmith@gnu.org>
376 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
378 * dep.h: Create alloc_dep() / free_dep() macros.
380 * implicit.c (pattern_search): Take advantage of the new
381 parse_file_seq() to add the directory prefix to each prereq.
383 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
384 all. Avoid reversing chains. Support adding prefixes.
385 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
386 cached/non-cached results.
387 (eval): Remove multi_glob() & invoke new parse_file_seq().
388 * rule.c (install_pattern_rule): Ditto.
389 * main.c (main): Ditto.
390 * implicit.c (pattern_search): Ditto.
391 * function.c (string_glob): Ditto.
392 * file.c (parse_prereqs): Ditto.
393 * default.c (set_default_suffixes): Ditto.
395 * variable.c (parse_variable_definition): Don't run off the end of
396 the string if it ends in whitespace (found with valgrind).
398 * commands.c (set_file_variables): Keep space for all targets in
399 $? if -B is given (found with valgrind).
401 2009-09-15 Paul Smith <psmith@gnu.org>
403 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
404 (xcalloc): Add new function.
405 * make.h: New declarations.
407 * ar.c (ar_glob_match): New calling method for concat().
408 * main.c (main): Ditto.
409 (decode_env_switches): Ditto.
410 * read.c (eval_makefile): Ditto.
411 (tilde_expand): Ditto.
412 (parse_file_seq): Ditto.
413 * variable.c (target_environment): Ditto.
414 (sync_Path_environment): Ditto.
416 * ar.c (ar_glob_match): Use xcalloc().
417 * dir.c (file_impossible): Ditto.
418 * file.c (enter_file): Ditto.
419 * job.c (new_job): Ditto.
420 * read.c (parse_file_seq): Ditto.
421 * vmsfunctions.c (opendir): Ditto.
423 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
425 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
426 inside the loop that looks up environment for PATH.
428 2009-08-31 Eli Zaretskii <eliz@gnu.org>
430 * function.c (windows32_openpipe): Update envp after calling
431 sync_Path_environment.
433 2009-08-02 Paul Smith <psmith@gnu.org>
435 * remake.c (notice_finished_file): Ensure file->cmds is not null
436 before looping through them. Fixes Savannah bug #21824.
438 * doc/make.texi (Wildcard Examples): Clarify when objects is
439 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
440 (Include): Clarify the behavior of -include.
441 Fixes Savannah bug #18963.
443 2009-08-01 Paul Smith <psmith@gnu.org>
445 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
446 etc. come on the command line. Fixes Savannah bug #27093.
448 * expand.c (expand_argument): If the argument is large enough use
449 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
451 * variable.c (do_variable_definition): Avoid using alloca() to
452 hold values, which can be large. Fixes Savannah bug #23960.
454 * job.c (new_job): Use memmove() instead of strcpy() since both
455 pointers are in the same memory block. Fixes Savannah bug #27148.
456 Patch by Petr Machata.
458 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
460 * job.c (construct_command_argv_internal): Add "ulimit" and
461 "unset" to the sh_cmds for Unixy shells.
463 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
465 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
466 that set make_cv_sys_gnu_glob, so they are also correctly set
467 when the cache has been populated before.
469 2009-07-04 Eli Zaretskii <eliz@gnu.org>
471 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
472 exist, as realpath(3) does where it's supported.
474 2006-07-04 Eli Zaretskii <eliz@gnu.org>
476 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
477 (abspath): Support systems that define HAVE_DOS_PATHS (have
478 drive letters in their file names). Use IS_PATHSEP instead of a
479 literal '/' comparison. Fixes Savannah bug #26886.
481 2009-06-14 Paul Smith <psmith@gnu.org>
483 * remake.c (update_file_1): Remember the original file we marked
484 as updating, so we can clear that flag again. If we find a target
485 via vpath, FILE might change.
486 (check_dep): Ditto. Fixes Savannah bug #13529.
487 Patch by Reid Madsen <reid.madsen@tek.com>.
489 2009-06-13 Paul Smith <psmith@gnu.org>
491 * doc/make.texi (MAKEFILES Variable): Be explicit that files
492 included by MAKEFILES cannot give default goals.
493 * read.c (eval): If set_default is not set, pass the no-default-goal
494 value when we read included makefiles. Fixes Savannah bug #13401.
496 * ar.c (ar_name): Ensure that targets with empty parens aren't
497 considered archive member references: archive members must have a
498 non-empty "member" string. Fixes Savannah bug #18435.
500 * function.c (string_glob): Rely on multi_glob() to determine
501 whether files exist or not. Remove call to file_exists_p() which
502 is not always correct. Fixes Savannah bug #21231.
503 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
504 then only files that really exist will be returned.
505 * dep.h: Add new argument to multi_glob().
506 * rule.c (install_pattern_rule): Ditto.
507 * read.c (eval): Ditto.
508 * main.c (main): Ditto.
509 * implicit.c (pattern_search): Ditto.
510 * file.c (parse_prereqs): Ditto.
511 * default.c (set_default_suffixes): Ditto.
513 2009-06-09 Paul Smith <psmith@gnu.org>
515 * commands.c (set_file_variables): If always_make_flag is set,
516 always add the prereq to $?. Fixes Savannah bug #17825.
518 * remake.c (update_file_1): When rebuilding deps of FILE, also try
519 to rebuild the deps of all the also_make targets for that file.
520 Fixes Savannah bug #19108.
522 * implicit.c (pattern_search): Undo test for is_target, added by
523 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
524 Rule Search Algorithm". Fixes Savannah bug #17752.
526 * main.c (clean_jobserver): Clear the jobserver_fds options and
527 set job_slots to the default when we clean up.
528 (define_makeflags): Return the new MAKEFLAGS value.
529 (main): Reset MAKEFLAGS in the environment when we re-exec.
530 Fixes Savannah bug #18124.
532 2009-06-08 Paul Smith <psmith@gnu.org>
534 * read.c (eval): Collapse continuations post-semicolon on target-
535 specific variables. Fixes Savannah bug #17521.
537 2009-06-07 Paul Smith <psmith@gnu.org>
539 * job.c (reap_children): For older systems without waitpid() (are
540 there any of these left?) run wait(2) inside EINTRLOOP to handle
541 EINTR errors. Fixes Savannah bug #16401.
543 * (various): Debug message cleanup. Fixes Savannah bug #16469.
545 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
547 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
548 not the end, to catch second expansion $(eval ...) defining new
549 target/prereq relationships during snap_deps.
550 Fixes Savannah bug #24622.
552 * read.c (record_files): The second-expansion "f->updating" hack
553 was not completely correct: if assumed that the target with
554 commands always had prerequisites; if one didn't then the ordering
555 was messed up. Fixed for now to use f->updating to decide whether
556 to preserve the last element in the deps list... but this whole
557 area of constructing and reversing the deps list is too confusing
558 and needs to be reworked. Fixes Savannah bug #21198.
560 2009-06-06 Paul Smith <psmith@gnu.org>
562 * hash.c (hash_insert): Remove useless test for NULL.
563 Fixes Savannah bug #21823.
565 * make.h: Move SET_STACK_SIZE determination to make.h.
566 * main.c (main): New global variable, STACK_LIMIT, holds the
567 original stack limit when make was started.
568 * job.c (start_job_command): Reset the stack limit, if we changed it.
569 Fixes Savannah bug #22010.
571 * remake.c (check_dep): Only set the target's state to not-started
572 if it's not already running. Found this while testing -j10 builds
573 of glibc: various targets were being rebuilt multiple times.
574 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
577 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
578 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
581 2009-06-04 Paul Smith <psmith@gnu.org>
583 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
585 * maintMakefile: Modify access of config and gnulib Savannah
586 modules to use GIT instead of CVS.
588 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
589 Fixes Savannah bug #24655.
591 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
592 this can happen during some invocations of $(eval ...) for example.
593 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
595 2009-06-02 Paul Smith <psmith@gnu.org>
597 * configure.in: Check for fileno()
598 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
599 for the makefile file so invocations of $(shell ...) don't inherit it.
600 Fixes Savannah bug #24277.
602 2009-06-01 Paul Smith <psmith@gnu.org>
604 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
605 expansion was handled incorrectly. Rework the default goal
606 handling to save the variable only. Remove default_goal_file and
608 * read.c (eval): Check default_goal_var, not default_goal_name.
609 * read.c (record_target_var): Don't check default_goal_file here.
611 2009-05-31 Paul Smith <psmith@gnu.org>
613 * main.c (main): Expand the .DEFAULT_GOAL variable before using
614 it, and if the multi_glob() returns nothing (say it expanded to
615 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
617 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
618 $(and ..) to the reference. Fixes Savannah bug #25694.
620 * make.1: Be clear that some recipes will be executed even with -n.
621 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
623 * doc/make.texi (Override Directive): Make more clear how
624 overrides and appends interact.
625 Elucidates part of Savannah bug #26207.
627 * read.c (record_target_var): Don't reset the origin on
628 target-specific variables; try_variable_definition() will handle
629 this correctly. Fixes Savannah bug #26207.
631 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
632 Fixes Savannah bug #25712.
634 * implicit.c (pattern_search): Keep a pointer to the beginning of
635 the filename and save that instead of the constructed pointer.
636 Fixes Savannah bug #26593.
637 Patch by Mark Seaborn <mrs@mythic-beasts.com>
639 2009-05-30 Paul Smith <psmith@gnu.org>
641 * doc/make.texi (Multi-Line): Add a description of the new abilities
642 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
643 "command sequence" vs. "recipe" syntax.
644 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
645 after a define, to create variables with those flavors.
647 2009-05-25 Paul Smith <psmith@gnu.org>
649 Reworked the parser for variable assignments to allow multiple
650 modifiers, and in any order. Also allows variable and
651 prerequisites to be modifier names ('export', 'private', etc.)
653 * NEWS: Add notes about user-visible changes.
655 * read.c (struct vmodifiers): Remember what modifiers were seen.
656 (parse_var_assignment): New function to parse variable assignments.
657 (eval): Call the new function. Handle variable assignments earlier.
659 * variable.c (parse_variable_definition): Only parse; don't create var.
660 (assign_variable_definition): Call parse, then create the var.
662 2009-05-24 Paul Smith <psmith@gnu.org>
664 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
665 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.

669 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
670 Fixes Savannah bug #25412.
672 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
673 prototype for xmalloc.
674 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
675 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
676 Loop over an array of extensions, instead of duplicating the same
677 code inline. Use SearchPath followed by CreateFile, instead of
678 the obsolete OpenFile. Fixes Savannah bug #17277.
679 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
680 to `find_file'. Fixes Savannah bug #25662.
682 2009-03-07 Eli Zaretskii <eliz@gnu.org>
684 * function.c (func_shell): Don't close pipedes[1] if it is -1.
685 Fixes Savannah bug #20495.
687 2009-02-28 Ralf Wildenhues <address@hidden>
689 * doc/make.texi (Instead of Execution): Document interaction of
690 -t with phony targets.
692 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
694 Introduce a new keyword "private" which applies to target-specific
695 variables and prevents their values from being inherited.
697 * variable.h (struct variable): Add private_var flag to each variable.
698 Add a flag to specify which list entry switches to the parent target.
699 * variable.c (define_variable_in_set): Initialize private_var flag.

701 (initialize_file_variables): Set next_is_parent appropriately.
702 (print_variable): Show the private_var flag.
703 * read.c (eval): Recognize the private keyword.
704 (record_target_var): Set private_var.
705 * doc/make.texi (Suppressing Inheritance): Add documentation.
707 2008-10-26 Paul Smith <psmith@gnu.org>
709 * configure.in: Check for strndup().

727 * job.c (construct_command_argv_internal): Avoid extra backslash
728 in batch-mode Unixy shells. Under DB_JOBS, display the contents
731 2008-05-31 Eli Zaretskii <eliz@gnu.org>
733 * README.W32.template: Remove obsolete text about non-support for
734 -jN without Unixy shell. Remove obsolete text about not supplying
735 Visual Studio project files (we do supply them). Modify text to
736 prefer GCC builds to MSC builds.
738 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
740 * doc/make.texi (Empty Targets): Fix typo.
742 2008-03-27 Paul Smith <psmith@gnu.org>
744 Fix Savannah bug #22379:
745 * ar.c (ar_glob_match): Zero the allocated structure.
746 * read.c (parse_file_seq): Ditto.
748 2008-03-08 Brian Dessent <brian@dessent.net>
750 * maintMakefile: Update Translation Project location.
752 2008-01-26 Eli Zaretskii <eliz@gnu.org>
754 * variable.c (target_environment): Don't use shell_var if its
755 `value' field is NULL.
757 2007-12-22 Eli Zaretskii <eliz@gnu.org>
759 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
761 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
762 (TEXINFOS): Value changed to `doc/make.texi'.
763 (.SUFFIXES): Use .texi instead of .texinfo.
764 (make.info, make.dvi): Depend on doc/make.texi.
765 (.texi.info): New target, instead of ".texinfo.info". Change -I
766 switch to $(MAKEINFO) to look in doc/. Use --no-split.
767 (.texi): New target, instead of ".texinfo". Change -I switch to
768 $(MAKEINFO) to look in doc/. Use --no-split.
769 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
770 switch to $(MAKEINFO) to look in doc/.
771 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
772 "*.i[0-9][0-9]" (due to --no-split above).
773 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
774 (html, make_1.html): New targets.
775 (.PHONY): Add "html".
776 (.SUFFIXES): Add .html.
778 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
780 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
781 HAVE_DECL_SYS_SIGLIST.
783 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
784 build does not use child_execute_job.
786 * variable.c (define_automatic_variables) [__MSDOS__]: Always
787 export the SHELL environment variable to the child.
789 2007-12-22 Eli Zaretskii <eliz@gnu.org>
791 * config.h.W32: Include sys/types.h.

798 2007-11-04 Paul Smith <psmith@gnu.org>
800 * doc/make.texi: Convert references to "commands", "command
801 lines", and "command script" to "recipe".
803 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
806 2007-10-27 Bruno Haible <bruno@clisp.org>
808 * remake.c (f_mtime): Print time difference values between 100 and
809 ULONG_MAX in fixed-point notation rather than in exponention notation.
811 2007-10-12 Eli Zaretskii <eliz@gnu.org>
813 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
814 a more complex value than a simple shell: if it's not a default
815 shell now then expand it and see if is a default shell then.
817 2007-10-10 Eli Zaretskii <eliz@gnu.org>
819 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
820 pathnames, with const strings.
821 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
822 from the template (used for building from CVS, not a dist).
824 2007-10-10 Paul Smith <psmith@gnu.org>
826 * make.h: Add a prototype for w32_kill() (change suggested by
827 Yongwei Wu <wuyongwei@gmail.com>).
829 2007-09-21 Eli Zaretskii <eliz@gnu.org>
831 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
834 2007-09-12 Paul Smith <psmith@gnu.org>

839 Provided by Diego Biurrun <diego@biurrun.de>
841 2007-09-11 Paul Smith <psmith@gnu.org>
843 * doc/make.texi (Special Variables): Moved this into the "How to
844 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
845 (MAKEFILE_LIST) No longer a section; this was added into the
846 "Special Variables" section.
847 (Rule Introduction): Reference .RECIPEPREFIX.
848 (Simple Makefile): Ditto.
849 (Rule Syntax): Ditto.
850 (Command Syntax): Ditto.
851 (Error Messages): Ditto.
853 2007-09-10 Paul Smith <psmith@gnu.org>
855 * commands.c (print_commands): Don't print an extra line in the
856 command scripts. Prefix the command scripts with cmd_prefix, not \t.
858 * read.c (construct_include_path): Add the full string to the cache; we
859 were chopping the last char.
861 * NEWS: Announce the .RECIPEPREFIX special variable.
862 * variable.c (lookup_special_var): Rename from handle_special_var().
863 (lookup_variable): Call the new name.
864 (set_special_var): New function: handle setting of special variables.
865 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
866 (do_variable_definition): Call it.

868 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
869 * main.c (main): Create the .RECIPEPREFIX special variable.
870 * read.c (eval): Remove the cmd_prefix characters from the command
871 scripts here, so they're not stored in the commands array at all,
872 rather than waiting and stripping them out during command construction.
873 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
875 2007-08-15 Paul Smith <psmith@gnu.org>
877 * doc/make.texi (GNU Free Documentation License): The fdl.texi
878 file has had the section info removed, so add some to make.texi
879 before we include it.
881 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
883 * remake.c (check_dep): Reset the target state for intermediate
884 files. They might have been considered before but not updated
885 then (order-only for example) but they will be this time.
886 Fixes Savannah bug #'s 3330 and 15919.
888 2007-07-21 Eli Zaretskii <eliz@gnu.org>
890 Fix Savannah bug #20549:
891 * function.c (func_shell): Call construct_command_argv with zero
893 * job.c (construct_command_argv_internal): New argument FLAGS; all
895 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
897 * job.h (construct_command_argv_internal): Update prototype.
899 2007-07-13 Paul Smith <psmith@gnu.org>
901 * file.c (expand_deps): Use variable_buffer as the start of the
902 buffer, not the original pointer (in case it was reallocated).
903 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
904 Fixes Savannah bug #20452.
906 2007-07-04 Paul Smith <psmith@gnu.org>
908 * (ALL FILES): Update to GPLv3.
909 * (ALL FILES): Update copyright for 2007.

915 * maintMakefile: Update Translation Project location.
917 2007-06-13 Paul Smith <psmith@gnu.org>
919 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
920 "Expansion of a deferred"
921 Fixes Savannah bug #20018.
923 * expand.c (variable_expand_for_file): Preserve the value of
924 reading_file rather than setting it to 0 at the end.
925 Fixes Savannah bug #20033.
927 2007-05-11 Paul Smith <psmith@gnu.org>
929 * job.c (new_job): Add debug info to specify where make found the
930 command script it is running to build a target.
931 Fixes Savannah bug #18617.
933 * default.c (default_suffixes,default_suffix_rules,default_variables):
934 Add support for Objective C. Fixes Savannah bug #16389.
935 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
937 * function.c (func_lastword): Initialize p.
939 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
940 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
941 Dave Korn <dave.korn@artimi.com>
943 2007-05-08 Paul Smith <psmith@gnu.org>
945 Fix Savannah bug #19656:
947 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
949 * make.h: Change all case-insensitive string compares to use
950 strcasecmp() (from POSIX). If we don't have that but do have one
951 of the others, define strcasecmp to be one of those instead. If
952 we don't have any, declare a prototype for our own version.
954 * misc.c (strcasecmp): Use this if we can't find any native
955 case-insensitive string comparison function.
956 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
957 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
959 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
960 strcasecmp() instead of stricmp().
961 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
962 instead of strcmpi().
963 * acinclude.m4: Remove the strcasecmp() check from here.
965 2007-03-21 Paul Smith <psmith@gnu.org>
967 * configure.in: Don't turn on case-insensitive file system support
968 if --disable-... is given. Fixes Savannah bug #19348.
970 2007-03-19 Paul Smith <psmith@gnu.org>
972 * ALL: Use the strcache for all file name strings, or other
973 strings which we will never free. The goal is to save memory by
974 avoiding duplicate copies of strings. However, at the moment this
975 doesn't save much memory in most situations: due to secondary
976 expansion we actually save prerequisite lists twice (once before
977 the secondary expansion, and then again after it's been parsed
978 into individual file names in the dep list). We will resolve this
979 in a future change, by doing the parsing up-front for targets
980 where secondary expansion is not set.
982 Moving things into the strcache also allows us to use const
983 pointers in many more places.
985 2007-01-03 Paul Smith <psmith@gnu.org>
987 * make.h (ENULLLOOP): Reset errno after each failed invocation of
988 the function, not just the first. Fixes Savannah bug #18680.
990 2006-11-18 Paul Smith <psmith@gnu.org>
992 * strcache.c (strcache_add_len): Don't allocate a new buffer
993 unless the string is not already nil-terminated. Technically this
994 is a violation of the standard, since we may be passed an array
995 that is not long enough to test one past. However, in make this
996 is never true since we only use nil-terminated strings or
999 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1001 * main.c: New global cmd_prefix, defaults to '\t'.
1002 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1005 * dir.c: Constified.
1006 (dir_contents_file_exists_p): Check for an error return from
1007 readdir(), just in case.
1009 * commands.c: Constified.
1010 * default.c: Constified.
1011 * expand.c: Constified.
1012 * function.c: Partial constification.
1013 * variable.c: Partial constification.
1014 * vmsify.c: Constification. Hard to test this but I hope I didn't
1016 * vpath.c: Partial constification.
1017 * w32/pathstuff.c: Partial constification.
1019 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1021 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1022 backslashes and drive letters as absolute.
1024 2006-10-22 Paul Smith <psmith@gnu.org>
1026 * main.c (struct command_switch): Use const and void*.
1028 2006-10-21 Paul Smith <psmith@gnu.org>
1031 * arscan.c: Constified.
1033 2006-09-30 Paul Smith <psmith@gnu.org>
1035 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1036 point to lastword since the example was updated.
1037 Fixes Savannah bug #16304.
1038 (Secondary Expansion): Correct example description.
1039 Fixes Savannah bug #16468.
1040 (Makefile Contents): Clarify that comments cannot appear within
1041 variable references or function calls.
1042 Fixes Savannah bug #16577.
1043 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1044 Fixes Savannah bug #17701.
1045 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1046 (Prerequisite Types): Added an example of using order-only
1047 prerequisites. Fixes Savannah bug #17880.
1048 (Rule Syntax): "lise" -> "list"
1049 (Multiple Rules): ... -> @dots{}
1050 (Splitting Lines): ditto.
1052 * remake.c (update_file_1): Prereqs that don't exist should be
1053 considered changed, for the purposes of $?.
1054 Fixes Savannah bug #16051.
1056 * make.1: Remove extraneous "+".
1057 Fixes Savannah bug #16652.
1059 2006-09-06 Paul D. Smith <psmith@gnu.org>

1074 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1075 sh_chars_sh for Windows platforms that emulate Unix.
1077 2006-05-07 Paul D. Smith <psmith@gnu.org>
1079 * README.OS2.template: Updates provided by Andreas Buening
1080 <andreas.buening@nexgo.de>.
1082 2006-04-30 Paul D. Smith <psmith@gnu.org>
1084 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1085 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1087 2006-04-26 Paul D. Smith <psmith@gnu.org>
1089 * README.cvs: Add a reminder to notify the GNU translation robot.
1091 * doc/make.texi: Change @direcategory (requested by Karl Berry).
1093 2006-04-20 Paul D. Smith <psmith@gnu.org>

1109 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1110 values from memory allocation functions: they return void* and so
1111 don't need to be cast. Also remove (char *) casts of arguments to

1143 2006-04-01 Paul D. Smith <psmith@gnu.org>
1145 Version 3.81 released.
1147 * NEWS: Updated for 3.81.
1149 * README.cvs: Mention that vpath builds are not supported out of
1150 CVS. Fixes Savannah bug #16236.

1154 2006-03-26 Paul D. Smith <psmith@gnu.org>
1156 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1157 support from automake, as described in the Texinfo manual.
1159 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1161 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1162 with lastslash, since the latter points to filename, not to

1165 Declare and define sh_chars_sh[].
1167 2006-03-23 Paul D. Smith <psmith@gnu.org>
1169 * configure.in: Look for build.sh.in in $srcdir so it will be
1170 built for remote configurations as well.
1172 * Makefile.am: Make sure to clean up build.sh during distclean.
1173 Fixes Savannah bug #16166.
1175 * misc.c (log_access): Takes a const char *.
1176 * function.c (fold_newlines): Takes an unsigned int *.
1177 Both fixes for Savannah bug #16170.
1179 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1181 * implicit.c (pattern_search): Call set_file_variables only
1182 if we have prerequisites that need second expansion. Fixes
1183 Savannah bug #16140.
1185 2006-03-19 Paul D. Smith <psmith@gnu.org>
1187 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1188 memory on hosts that don't support it directly.

1191 make sure I don't forget any).
1193 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1195 (die): Cleanup code was removed from here; call the new function.
1196 (main): If we are re-execing, clean up the jobserver first so we

1198 Reported by Craig Fithian <craig.fithian@citigroup.com>
1200 2006-03-17 Paul D. Smith <psmith@gnu.org>
1202 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1203 allow multiple concurrent runs.
1204 Patch from Joseph Myers <joseph@codesourcery.com>
1206 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1208 * dep.h (struct dep): Add the stem field.
1209 * misc.c (alloc_dep, free_dep): New functions.
1210 (copy_dep_chain): Copy stem.
1211 (free_dep_chain): Use free_dep.
1212 * read.c (record_files): Store stem in the dependency line.
1213 * file.c (expand_deps): Use stem stored in the dependency line. Use
1214 free_dep_chain instead of free_ns_chain.
1215 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1216 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1217 * main.c (main, handle_non_switch_argument): Ditto.
1218 * remake.c (check_dep): Ditto.

1221 2006-03-14 Paul D. Smith <psmith@gnu.org>
1223 * expand.c (variable_append): Instead of appending everything then
1224 expanding the result, we expand (or not, if it's simple) each part
1226 (allocated_variable_append): Don't expand the final result.
1227 Fixes Savannah bug #15913.
1229 2006-03-09 Paul Smith <psmith@gnu.org>
1231 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1232 listed non-existent files as changed. Turns out there's a bug in
1233 the Linux kernel builds which means that this change causes
1234 everything to rebuild every time. We will re-introduce this fix
1235 in the next release, to give them time to fix their build system.
1236 Fixes Savannah bug #16002.
1237 Introduces Savannah bug #16051.
1239 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1246 locator function find_and_set_default_shell if SHELL came from the
1249 2006-02-20 Paul D. Smith <psmith@gnu.org>
1251 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1252 to be null; don't core in that case.
1254 2006-02-19 Paul D. Smith <psmith@gnu.org>
1256 * commands.c (set_file_variables): Realloc, not malloc, the static
1257 string values to avoid memory leaks.
1259 * expand.c (recursively_expand_for_file): Only set reading_file to
1260 an initialized value.
1262 * implicit.c (pattern_search): We need to make a copy of the stem
1263 if we get it from an intermediate dep, since those get freed.
1265 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1267 (enter_file) [VMS]: Ditto.
1268 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1270 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1272 * job.c (construct_command_argv_internal): Fix last change.
1274 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1275 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1276 the calls to _beginthreadex.
1278 * expand.c (recursively_expand_for_file): Initialize `save' to
1279 prevent compiler warnings.
1281 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1283 * job.c (construct_command_argv_internal): Don't create a temporary
1284 script/batch file if we are under -n. Call _setmode to switch the
1285 script file stream to text mode.
1287 2006-02-17 Paul D. Smith <psmith@gnu.org>
1289 * variable.c (merge_variable_set_lists): Don't try to merge the
1290 global_setlist. Not only is this useless, but it can lead to
1291 circularities in the linked list, if global_setlist->next in one
1292 list gets set to point to another list which also ends in
1294 Fixes Savannah bug #15757.
1296 2006-02-15 Paul D. Smith <psmith@gnu.org>
1298 Fix for Savannah bug #106.
1300 * expand.c (expanding_var): Keep track of which variable we're
1301 expanding. If no variable is being expanded, it's the same as
1303 * make.h (expanding_var): Declare it.
1304 * expand.c (recursively_expand_for_file): Set expanding_var to the
1305 current variable we're expanding, unless there's no file info in
1306 it (could happen if it comes from the command line or a default
1307 variable). Restore it before we exit.
1308 * expand.c (variable_expand_string): Use the expanding_var file
1309 info instead of the reading_file info.
1310 * function.c (check_numeric): Ditto.
1312 (func_wordlist): Ditto.
1313 (func_error): Ditto.
1314 (expand_builtin_function): Ditto.
1315 (handle_function): Ditto.
1317 2006-02-14 Paul D. Smith <psmith@gnu.org>
1319 * read.c (eval): Even if the included filenames expands to the
1320 empty string we still need to free the allocated buffer.
1322 * implicit.c (pattern_search): If we allocated a variable set for
1323 an impossible file, free it.
1324 * variable.c (free_variable_set): New function.
1325 * variable.h: Declare it.
1327 * read.c (read_all_makefiles): Makefile names are kept in the
1328 strcache, so there's never any need to alloc/free them.
1331 * main.c (main): Add "archives" to the .FEATURES variable if
1332 archive support is enabled.
1333 * doc/make.texi (Special Variables): Document it.
1335 2006-02-13 Paul D. Smith <psmith@gnu.org>
1337 * implicit.c (pattern_search): Add checking for DOS pathnames to
1338 the pattern rule target LASTSLASH manipulation.

1343 * (ALL FILES): Updated copyright and license notices.
1345 2006-02-10 Paul D. Smith <psmith@gnu.org>
1347 A new internal capability: the string cache is a read-only cache
1348 of strings, with a hash table interface for fast lookup. Nothing
1349 in the cache will ever be freed, so there's no need for reference
1350 counting, etc. This is the beginning of a full solution for
1351 Savannah bug #15182, but for now we only store makefile names here.
1353 * strcache.c: New file. Implement a read-only string cache.
1354 * make.h: Add prototypes for new functions.
1355 * main.c (initialize_global_hash_tables): Initialize the string cache.
1356 (print_data_base): Print string cache stats.
1357 * read.c (eval_makefile): Use the string cache to store makefile
1358 names. Rewrite the string allocation to be sure we free everything.
1360 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1362 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1363 directory time stamp didn't change, except on FAT filesystems.
1364 Suggested by J. David Bryan <jdbryan@acm.org>.
1366 2006-02-09 Paul D. Smith <psmith@gnu.org>
1368 * function.c (func_or): Implement a short-circuiting OR function.
1369 (func_and): Implement a short-circuiting AND function.
1370 (function_table_init): Update the table with the new functions.
1371 * doc/make.texi (Conditional Functions): Changed the "if" section
1372 to one on general conditional functions. Added documentation for
1373 $(and ...) and $(or ...) functions.
1374 * NEWS: Note new $(and ...) and $(or ...) functions.

1385 * vpath.c (selective_vpath_search): If the file we find has a
1386 timestamp from -o or -W, use that instead of the real time.
1387 * remake.c (f_mtime): If the mtime is a special token from -o or
1388 -W, don't overwrite it with the real mtime.
1389 Fixes Savannah bug #15341.
1391 Updates from Markus Mauhart <qwe123@chello.at>:
1393 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1394 (process_signal, process_last_err, process_exit_code): Manage
1395 invalid handle values.
1396 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1397 manage invalid handles; remove them.

1399 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1406 Fixes Savannah bug #15533.
1407 * filedef.h (struct file): Add a new LAST pointer.
1409 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1410 the comparison. For 64-bits systems the result of the subtraction
1411 might not fit into an int. Use comparison instead.
1412 Fixes Savannah bug #15534.
1414 * doc/make.texi: Update the chapter on writing commands to reflect
1415 the changes made in 3.81 for backslash/newline and SHELL handling.

1419 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1420 variable st is not used when it's not initialized.

1435 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1437 * remake.c (update_goal_chain): Set g->changed instead of
1438 incrementing it, as it is only 8-bit wide, and could overflow if
1439 many commands got started in update_file.
1441 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1443 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1461 the shell is not sh.exe.
1463 * job.c (create_batch_file): Renamed from create_batch_filename;
1464 all callers changed. Don't close the temporary file; return its
1465 file descriptor instead. New arg FD allows to return the file
1467 (construct_command_argv_internal): Use _fdopen instead of fopen to
1468 open the batch file.
1470 2006-01-04 Paul D. Smith <psmith@gnu.org>

1500 handling of backslash-newline sequences. Mention the differences
1501 on MS-DOS and MS-Windows.
1503 * NEWS: More details about building the MinGW port and a pointer
1504 to README.W32. Fix the section name that describes the new
1505 backward-incompatible processing of backslash-newline sequences.
1506 The special processing of SHELL set to "cmd" is only relevant to
1507 MS-Windows, not MS-DOS.
1509 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1511 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1512 to DWORD, to avoid compiler warnings.

1537 2005-12-11 Paul D. Smith <psmith@gnu.org>
1539 * implicit.c (pattern_search): If 2nd expansion is not set for
1540 this implicit rule, replace the pattern with the stem directly,
1541 and don't re-expand the variable list. Along with the other
1542 .SECONDEXPANSION changes below, fixes bug #13781.
1544 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1546 * implicit.c (pattern_search): Mark other files that this rule
1547 builds as targets so that they are not treated as intermediates

1606 2005-10-16 Paul D. Smith <psmith@gnu.org>
1608 * main.c (main): Set CURDIR to be a file variable instead of a
1609 default, so that values of CURDIR inherited from the environment
1610 won't override the make value.
1612 2005-09-26 Paul D. Smith <psmith@gnu.org>
1614 * job.c (construct_command_argv_internal): If the line is empty
1615 remember to free the temporary argv strings.
1618 2005-09-16 Paul D. Smith <psmith@gnu.org>
1620 * job.c (start_job_command): The noerror flag is a boolean (single
1621 bit); set it appropriately.
1622 Reported by Mark Eichin <eichin@metacarta.com>
1624 2005-08-29 Paul D. Smith <psmith@gnu.org>
1626 * function.c (func_error): On Windows, output from $(info ...)
1627 seems to come in the wrong order. Try to force it with fflush().
1629 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1631 * read.c (record_files): Move code that sets stem for static
1632 pattern rules out of the if (!two_colon) condition so it is
1633 also executed for two-colon rules. Fixes Savannah bug #13881.
1635 2005-08-08 Paul D. Smith <psmith@gnu.org>
1637 * make.h: Don't test that __STDC__ is non-0. Some compilers
1638 (Windows for example) set it to 0 to denote "ISO C + extensions".
1641 2005-08-07 Paul D. Smith <psmith@gnu.org>
1643 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1644 conditional (slightly different version of a fix from Eli).
1646 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1647 If make is running in parallel without -k and two jobs die in a
1648 row, but not too close to each other, then make will quit without
1649 waiting for the rest of the jobs to die.
1651 * main.c (die): Don't reset err before calling reap_children() the
1652 second time: we still want it to be in the error condition.
1653 * job.c (reap_children): Use a static variable, rather than err,
1654 to control whether or not the error message should be printed.
1656 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1658 * w32/subproc/sub_proc.c: Include signal.h.
1659 (process_pipe_io, process_file_io): Pass a pointer to a local
1660 DWORD variable to GetExitCodeProcess. If the exit code is
1661 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1663 * job.c [WINDOWS32]: Include windows.h.
1664 (main_thread) [WINDOWS32]: New global variable.
1665 (reap_children) [WINDOWS32]: Get the handle for the main thread
1666 and store it in main_thread.
1668 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1669 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1670 doing anything else. When we are done, close the main thread
1671 handle and exit with status 130.
1673 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1675 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1678 * main.c (find_and_set_default_shell): If found a DOSish shell,
1679 set sh_found and the value of default_shell, and report the
1680 findings in debug mode.
1682 * job.c (construct_command_argv_internal): Check unixy_shell, not
1683 no_default_sh_exe, to decide whether to use Unixy or DOSish
1686 * README.W32: Update with info about the MinGW build.
1688 * build_w32.bat: Support MinGW.
1690 * w32/subproc/build.bat: Likewise.
1692 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1693 printing DWORD args.
1695 * function.c (windows32_openpipe): Fix format strings for printing
1698 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1700 (start_job_command): Fix format string for printing the result of
1702 (start_job_command) [WINDOWS32]: Do not define.
1703 (exec_command): Fix format string for printing HANDLE args.
1705 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1706 to avoid compiler warnings.
1707 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1708 (Note: some of these fixes were submitted independently by J. Grant)
1710 2005-07-30 J. Grant <jg@jguk.org>
1712 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1713 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1714 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1716 2005-07-15 Paul Smith <psmith@gnu.org>
1718 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1719 we don't have a POSIX shell, then revert to the old
1720 backslash-newline behavior (where they are stripped).
1723 2005-07-08 Paul D. Smith <psmith@gnu.org>
1725 * config.h.W32.template: Reorder to match the standard config.h,
1726 for easier comparisons.
1727 From J. Grant <jg@jguk.org>
1729 * maintMakefile: Remove .dep_segment before overwriting it, in
1730 case it's not writable or noclobber is set.
1731 * expand.c (variable_expand_string): Cast result of pointer
1732 arithmetic to avoid a warning.
1733 * main.c (switches): Add full-fledged final initializer.
1735 2005-07-06 Paul D. Smith <psmith@gnu.org>
1737 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1738 * signame.c (strsignal): If we found _sys_siglist[] or
1739 __sys_siglist[] use those instead of sys_siglist[].
1740 From Albert Chin <china@thewrittenword.com>
1742 2005-07-04 Paul D. Smith <psmith@gnu.org>
1744 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1745 globfree(); set up to use the GNU versions.
1746 From Martin Zinser <zinser@zinser.no-ip.info>
1748 2005-07-03 Paul D. Smith <psmith@gnu.org>
1750 From J. Grant <jg@jguk.org>:
1752 * README.W32.template: Update the Windows and tested MSVC versions.
1753 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1754 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1755 * build_w32.bat: Ditto.
1756 * w32/subproc/build.bat: Ditto.
1758 2005-06-28 Paul D. Smith <psmith@gnu.org>
1760 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1761 declaration was checked but not present.
1763 2005-06-27 Paul D. Smith <psmith@gnu.org>
1765 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1766 to unsigned long. Fixes Savannah bug #13550.
1768 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1769 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1770 Fixes Savannah bug #13551.
1772 2005-06-26 Paul D. Smith <psmith@gnu.org>
1774 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1775 it if ANSI_STRING is not set.
1777 2005-06-25 Paul D. Smith <psmith@gnu.org>
1779 * read.c (eval): If no filenames are passed to any of the
1780 "include" variants, don't print an error.
1781 * doc/make.texi (Include): Document this.
1782 Fixes Savannah bug #1761.
1784 * job.c (construct_command_argv_internal): Sanitize handling of
1785 backslash/newline pairs according to POSIX: that is, keep the
1786 backslash-newline in the command script, but remove a following
1787 TAB character, if present. In the fast path, make sure that the
1788 behavior matches what the shell would do both inside and outside
1789 of quotes. In the slow path, quote the backslash and put a
1790 literal newline in the string.
1791 Fixes Savannah bug #1332.
1792 * doc/make.texi (Execution): Document the new behavior and give
1794 * NEWS: Make a note of the new behavior.
1796 * make.h [WINDOWS32]: #include <direct.h>.
1797 Fixes Savannah bug #13478.
1799 * remake.c (name_mtime): If the stat() of a file fails and the -L
1800 option was given and the file is a symlink, take the best mtime of
1801 the symlink we can get as the mtime of the file and don't fail.
1802 Fixes Savannah bug #13280.
1804 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1805 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1806 inside a variable reference. Make this function static as it's
1808 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1809 parsing an unexpanded line looking for semicolons.
1810 Fixes Savannah bug #1454.
1811 * misc.c (remove_comments): Move this to read.c and make it static
1812 as it's only used there. Call find_char_unquote() with new arg.
1813 * make.h: Remove prototypes for find_char_unquote() and
1814 remove_comments() since they're static now.
1816 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1817 its export flag and obtain its value. When we need to re-exec,
1818 increment the value and add it into the environment.
1819 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1820 * NEWS: Mention MAKE_RESTARTS.
1821 * main.c (always_make_set): New variable. Change the -B option to
1822 set this one instead.
1823 (main): When checking makefiles, only set always_make_flag if
1824 always_make_set is set AND the restarts flag is 0. When building
1825 normal targets, set it IFF always_make_set is set.
1826 (main): Avoid infinite recursion with -W, too: only set what-if
1827 files to NEW before we check makefiles if we've never restarted
1828 before. If we have restarted, set what-if files to NEW _after_ we
1830 Fixes Savannah bug #7566:
1832 2005-06-17 Paul D. Smith <psmith@gnu.org>
1834 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1835 in the prerequisites list.
1837 2005-06-12 Paul D. Smith <psmith@gnu.org>
1839 Fix Savannah bug # 1328.
1841 * configure.in: Check for atexit().
1842 * misc.c (close_stdout): Test stdout to see if writes to it have
1843 failed. If so, be sure to exit with a non-0 error code. Based on
1844 code found in gnulib.
1845 * make.h: Prototype.
1846 * main.c (main): Install close_stdout() with atexit().
1848 2005-06-10 Paul D. Smith <psmith@gnu.org>
1850 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1852 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1853 headers; make vmsWaitForChildren() static; extern vmsify().
1854 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1855 Don't create child_execute_job() here (it's in vmsjobs.c).
1856 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1858 2005-06-09 Paul D. Smith <psmith@gnu.org>
1860 * variable.c (push_new_variable_scope): File variables point
1861 directly to the global_setlist variable. So, inserting a new
1862 scope in front of that has no effect on those variables: they
1863 don't go through current_variable_set_list. If we're pushing a
1864 scope and the current scope is global, push it "the other way" so
1865 that the new setlist is in the global_setlist variable, and
1866 next points to a new setlist with the global variable set.
1867 (pop_variable_scope): Properly undo a push with the new
1869 Fixes Savannah bug #11913.
1871 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1873 * job.c (reap_children): Don't die of the command failed but
1874 the dontcare flag is set. Fixes Savannah bug #13216.
1876 * implicit.c (pattern_search): When creating a target from
1877 an implicit rule match, lookup pattern target and set precious
1878 flag in a newly created target. Fixes Savannah bug #13218.
1880 2005-05-13 Paul D. Smith <psmith@gnu.org>
1882 Implement "if... else if... endif" syntax.
1884 * read.c (eval): Push all checks for conditional words ("ifeq",
1885 "else", etc.) down into the conditional_line() function.
1886 (conditional_line): Rework to allow "else if..." clause. New
1887 return value -2 for lines which are not conditionals. The
1888 ignoring flag can now also be 2, which means "already parsed a
1889 true branch". If that value is seen no other branch of this
1890 conditional can be considered true. In the else parsing if there
1891 is extra text after the else, invoke conditional_line()
1892 recursively to see if it's another conditional. If not, it's an
1893 error. If so, raise the conditional value to this level instead
1894 of creating a new conditional nesting level. Special check for
1895 "else" and "endif", which aren't allowed on the "else" line.
1896 * doc/make.texi (Conditional Syntax): Document the new syntax.
1898 2005-05-09 Paul D. Smith <psmith@gnu.org>
1900 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1901 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1902 recurses to the w32 directory, even on non-Windows systems. Use
1903 the method suggested in the automake manual.
1904 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1905 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1907 2005-05-07 Paul D. Smith <psmith@gnu.org>
1909 * main.c (die): If we're dying with a fatal error (not that a
1910 command has failed), write back any leftover tokens before we go.
1912 * job.c (set_child_handler_action_flags): If there are jobs
1913 waiting for the load to go down, set an alarm to go off in 1
1914 second. This allows us to wake up from a potentially long-lasting
1915 read() and start a new job if the load has gone down. Turn it off
1917 (job_noop): Dummy signal handler function.
1918 (new_job): Invoke it with the new semantics.
1920 * docs/make.texi: Document secondary expansion. Various cleanups
1923 2005-05-03 Paul D. Smith <psmith@gnu.org>
1925 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1926 the targets which are to ultimately be made are called "goals";
1927 see the GNU make manual. Also, MAKECMDGOALS, etc.
1929 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1930 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1931 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1933 2005-05-02 Paul D. Smith <psmith@gnu.org>
1935 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1936 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1937 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1938 functions to vmsjobs.c. #include it into jobs.c.
1940 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1941 jobserver tokens. I found that this happens when an exported
1942 recursive variable contains a $(shell ...) function reference: in
1943 this situation we could "forget" to write back a token.
1945 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1946 we have. It's not reliable to depend on the number of children in
1947 our linked list so keep a separate count.
1948 (new_job): Check jobserver_tokens rather than children &&
1949 waiting_jobs. Increment jobserver_tokens when we get one.
1950 (free_child): If jobserver_tokens is 0, internal error. If it's
1951 >1, write a token back to the jobserver pipe (we don't write a
1952 token for the "free" job). Decrement jobserver_tokens.
1954 * main.c: Add variable master_job_slots.
1955 (main): Set it to hold the number of jobs requested if we're the
1956 master process, when using the jobserver.
1957 (die): Sanity checks: first test jobserver_tokens to make sure
1958 this process isn't holding any tokens we didn't write back.
1959 Second, if master_job_slots is set count the tokens left in the
1960 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1962 2005-04-24 Paul D. Smith <psmith@gnu.org>
1964 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1965 with -l# can lose jobserver tokens, because waiting jobs are not
1966 consulted properly when checking for the "free" token.
1968 * job.c (free_child): Count waiting_jobs as having tokens.
1969 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1970 handle jobs waiting for the load to drop.
1972 2005-04-23 Paul D. Smith <psmith@gnu.org>
1974 * main.c (main): Be careful to not core if a variable setting in
1975 the environment doesn't contain an '='. This is illegal but can
1976 happen in broken setups.
1977 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1979 2005-04-12 Paul D. Smith <psmith@gnu.org>
1981 The second expansion feature causes significant slowdown. Timing
1982 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1983 read the makefile before the feature, to 11+s to do the same
1984 operations after the feature. Additionally, memory usage
1985 increased drastically. To fix this I added some intelligence that
1986 avoids the overhead of the second expansion unless it's required.
1988 * dep.h: Add a new boolean field, need_2nd_expansion.
1990 * read.c (eval): When creating the struct dep for the target,
1991 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1992 (record_files): If there's a "%" in a static pattern rule, it gets
1993 converted to "$*" so set need_2nd_expansion to 1.
1995 * file.c (expand_deps): Rework to be more efficient. Only perform
1996 initialize_file_variables(), set_file_variables(), and
1997 variable_expand_for_file() if the need_2nd_expansion is set.
1999 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2000 (pattern_search): Ditto.
2001 * main.c (handle_non_switch_argument): Ditto.
2003 * read.c (read_all_makefiles): Ditto.
2004 (eval_makefile): Ditto.
2006 2005-04-07 Paul D. Smith <psmith@gnu.org>
2008 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2009 * variable.c (sync_Path_environment): Ditto.
2010 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2012 * main.c (main): Define the .FEATURES variable.
2013 * NEWS: Announce .FEATURES.
2014 * doc/make.texi (Special Variables): Document .FEATURES.
2016 * remake.c (check_dep): If a file is .PHONY, update it even if
2017 it's marked intermediate. Fixes Savannah bug #12331.
2019 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2021 * file.c (expand_deps): Factor out the second expansion and
2022 prerequisite line parsing logic from snap_deps().
2024 * file.c (snap_deps): Use expand_deps(). Expand and parse
2025 prerequisites of the .SUFFIXES special target first. Fixes
2026 Savannah bug #12320.
2028 2005-03-13 Paul D. Smith <psmith@gnu.org>
2030 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2033 2005-03-11 Paul D. Smith <psmith@gnu.org>
2035 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2036 available, not undefined (from Earnie Boyd).
2038 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2040 * implicit.c (pattern_search): Mark an intermediate target as
2041 precious if it happened to be a prerequisite of some (other)
2042 target. Fixes Savannah bug #12267.
2044 2005-03-09 Paul D. Smith <psmith@gnu.org>
2046 * read.c (eval_makefile): Add alloca(0).
2047 (eval_buffer): Ditto.
2049 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2051 * main.c (main): Use o_file instead of o_default when defining
2052 the .DEFAULT_TARGET special variable.
2053 * read.c (eval): Use define_variable_global() instead of
2054 define_variable() when setting new value for the .DEFAULT_TARGET
2055 special variable. Fixes Savannah bug #12266.
2057 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2059 * imlicit.c (pattern_search): Mark files for which an implicit
2060 rule has been found as targets. Fixes Savannah bug #12202.
2062 2005-03-04 Paul D. Smith <psmith@gnu.org>
2065 * doc/make.texi (Automatic Variables): Document $|.
2067 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2069 * read.c (record_files): Instead of substituting % with
2070 actual stem value in dependency list replace it with $*.
2071 This fixes stem triple expansion bug.
2073 * implicit.c (pattern_search): Copy stem to a separate
2074 buffer and make it a properly terminated string. Assign
2075 this buffer instead of STEM (which is not terminated) to
2076 f->stem. Instead of substituting % with actual stem value
2077 in dependency list replace it with $*. This fixes stem
2078 triple expansion bug.
2080 2005-03-01 Paul D. Smith <psmith@gnu.org>
2082 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2083 on Windows, as it takes a handle not a pid. Just exit.
2084 Fix from patch #3679, provided by Alessandro Vesely.
2086 * configure.in: Update check for sys_siglist[] from autoconf manual.
2087 * signame.c (strsignal): Update to use the new autoconf macro.
2089 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2091 * read.c (record_files): Add a check for the list of prerequisites
2092 of a static pattern rule being empty. Fixes Savannah bug #12180.
2094 2005-02-28 Paul D. Smith <psmith@gnu.org>
2096 * doc/make.texi (Text Functions): Update docs to allow the end
2097 ordinal for $(wordlist ...) to be 0.
2098 * function.c (func_wordlist): Fail if the start ordinal for
2099 $(wordlist ...) is <1. Matches documentation.
2100 Resolves Savannah support request #103195.
2102 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2103 previously we were stopping when !-q, exactly the opposite. This
2104 has been wrong since version 1.34, in 1994!
2105 (update_file): If we got an error don't break out to run more
2106 double-colon rules: just return immediately.
2107 Fixes Savannah bug #7144.
2109 2005-02-27 Paul D. Smith <psmith@gnu.org>
2111 * misc.c (end_of_token): Make argument const.
2112 * make.h: Update prototype.
2114 * function.c (abspath, func_realpath, func_abspath): Use
2115 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2116 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2117 * read.c (record_files): Ditto.
2118 * variable.c (do_variable_definition): Ditto.
2120 * function.c (func_error): Create a new function $(info ...) that
2121 simply prints the message to stdout with no extras.
2122 (function_table_init): Add new function to the table.
2123 * NEWS: Add $(info ...) reference.
2124 * doc/make.texi (Make Control Functions): Document it.
2126 New feature: if the system supports symbolic links, and the user
2127 provides the -L/--check-symlink-time flag, then use the latest
2128 mtime between the symlink(s) and the target file.
2130 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2131 readlink(). If both are available, define MAKE_SYMLINKS.
2132 * main.c: New variable: check_symlink_flag.
2133 (usage): Add a line for -L/--check-symlink-times to the help string.
2134 (switches): Add -L/--check-symlink-times command line argument.
2135 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2136 print a warning and disable it again.
2137 * make.h: Declare check_symlink_flag.
2138 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2139 if the file is a symlink then check each link in the chain and
2140 choose the NEWEST mtime we find as the mtime for the file. The
2141 newest mtime might be the file itself!
2142 * NEWS: Add information about this new feature.
2143 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2145 Avoid core dumps described in Savannah bug # 12124:
2147 * file.c: New variable snapped_deps remember whether we've run
2149 (snap_deps): Set it.
2150 * filedef.h: Extern it.
2151 * read.c (record_files): Check snapped_deps; if it's set then
2152 we're trying to eval a new target/prerequisite relationship from
2153 within a command script, which we don't support. Fatal.
2155 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2157 Implementation of the .DEFAULT_TARGET special variable.
2159 * read.c (eval): If necessary, update default_target_name when
2161 * read.c (record_files): Update default_target_file if
2162 default_target_name has changed.
2163 * main.c (default_target_name): Define.
2164 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2165 default_target_name is set use default_target_file as a root
2167 * filedef.h (default_target_name): Declare.
2168 * dep.h (free_dep_chain):
2169 * misc.c (free_dep_chain): Change to operate on struct nameseq
2170 and change name to free_ns_chain.
2171 * file.c (snap_deps): Update to use free_ns_chain.
2173 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2175 Implementation of the second expansion in explicit rules,
2176 static pattern rules and implicit rules.
2178 * read.c (eval): Refrain from chopping up rule's dependencies.
2179 Store them in a struct dep as a single dependency line. Remove
2180 the code that implements SySV-style automatic variables.
2182 * read.c (record_files): Adjust the code that handles static
2183 pattern rules to expand all percents instead of only the first
2184 one. Reverse the order in which dependencies are stored so that
2185 when the second expansion reverses them again they appear in
2186 the makefile order (with some exceptions, see comments in
2187 the code). Remove the code that implements SySV-style automatic
2190 * file.c (snap_deps): Implement the second expansion and chopping
2191 of dependency lines for explicit rules.
2193 * implicit.c (struct idep): Define an auxiliary data type to hold
2194 implicit rule's dependencies after stem substitution and
2197 * implicit.c (free_idep_chain): Implement.
2199 * implicit.c (get_next_word): Implement helper function for
2200 parsing implicit rule's dependency lines into words taking
2201 into account variable expansion requests. Used in the stem
2204 * implicit.c (pattern_search): Implement the second expansion
2205 for implicit rules. Also fixes bug #12091.
2207 * commands.h (set_file_variables): Declare.
2208 * commands.c (set_file_variables): Remove static specifier.
2210 * dep.h (free_dep_chain): Declare.
2211 * misc.c (free_dep_chain): Implement.
2213 * variable.h (variable_expand_for_file): Declare.
2214 * expand.c (variable_expand_for_file): Remove static specifier.
2216 * make.h (strip_whitespace): Declare.
2217 * function.c (strip_whitespace): Remove static specifier.
2219 2005-02-26 Paul D. Smith <psmith@gnu.org>
2221 * main.c (main): Check for ferror() when reading makefiles from stdin.
2222 Apparently some shells in Windows don't close pipes properly and
2225 2005-02-24 Jonathan Grant <jg@jguk.org>
2227 * configure.in: Add MinGW configuration options, and extra w32 code
2229 * Makefile.am: Add MinGW configuration options, and extra w32 code
2231 * main.c: Determine correct program string (after last \ without .exe).
2232 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2234 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2235 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2236 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2237 environment support.
2239 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2241 * function.c (func_shell): When initializing error_prefix, check
2242 that reading file name is not null. This fixes long-standing
2243 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2245 2005-02-09 Paul D. Smith <psmith@gnu.org>
2247 * maintMakefile: Update the CVS download URL to simplify them.
2248 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2249 downloading the .texi files from Savannah now.
2251 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2253 * main.c (handle_non_switch_argument): Only add variables to
2254 command_variables if they're not already there: duplicate settings
2255 waste space and can be confusing to read.
2257 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2258 this header is never included by non-WINDOWS32 code, and it
2259 requires <config.h> to define which isn't always included first.
2261 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2262 testing MINGW32 versions.
2264 * main.c (log_working_directory): flush stdout to be sure the WD
2265 change is printed before any stderr messages show up.
2267 2005-02-01 Paul D. Smith <psmith@gnu.org>
2269 * maintMakefile (po_repo): Update the GNU translation site URL.
2271 2004-12-01 Paul D. Smith <psmith@gnu.org>
2273 * main.c (main): Change char* env_shell to struct variable shell_var.
2274 * variable.c (target_environment): Use new shell_var.
2276 2004-11-30 Paul D. Smith <psmith@gnu.org>
2278 * configure.in: The old way we avoided creating build.sh from
2279 build.sh.in before build.sh.in exists doesn't work anymore; we
2280 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2281 the help!). This also keeps automake from complaining.
2282 * Makefile.am (README): Add a dummy target so automake won't
2283 complain that this file doesn't exist when we checkout from CVS.
2284 * maintMakefile (.dep_segment): Rewrite this rule since newer
2285 versions of automake don't provide DEP_FILES.
2287 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2289 Implementation of `realpath' and `abspath' built-in functions.
2291 * configure.in: Check for realpath.
2292 * function.c (abspath): Return an absolute file name that does
2293 not contain any `.' or `..' components, nor repeated `/'.
2294 * function.c (func_abspath): For each name call abspath.
2295 * function.c (func_realpath): For each name call realpath
2296 from libc or delegate to abspath if realpath is not available.
2297 * doc/make.texi (Functions for File Names): Document new functions.
2298 * doc/make.texi (Quick Reference): Ditto.
2300 2004-11-28 Paul D. Smith <psmith@gnu.org>
2302 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2303 arguments. Fixes bug #10252.
2305 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2307 * main.c (main): Set SHELL to v_noexport by default. Remember the
2308 original environment setting of SHELL in the env_shell variable.
2309 * main.h: Export new env_shell variable.
2310 * variable.c (target_environment): If we find a v_noexport
2311 variable for SHELL, add a SHELL variable with the env_shell value.
2312 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2313 * doc/make.texi (Variables/Recursion): Ditto.
2315 2004-11-28 Paul D. Smith <psmith@gnu.org>
2317 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2318 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2319 Patch by Alessandro Vesely.
2321 2004-11-12 Paul D. Smith <psmith@gnu.org>
2323 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2324 the command line if it's inside a string.
2325 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2327 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2329 * function.c (func_lastword): New function: return last word
2330 from the list of words.
2331 * doc/make.texi: Document $(lastword ). Fix broken links in
2332 Quick Reference section.
2334 2004-10-06 Paul D. Smith <psmith@gnu.org>
2336 Apply patch from Alessandro Vesely, provided with bug # 9748.
2337 Fix use of tmpnam() to work with Borland C.
2339 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2340 construction of a temporary filename, and call new function
2341 create_batch_filename().
2342 (create_batch_filename) [WINDOWS32]: New function to create a
2345 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2347 * read.c (record_target_var): Expand simple pattern-specific
2349 * variable.c (initialize_file_variables): Do not expand simple
2350 pattern-specific variable.
2352 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2354 * remake.c (update_file_1): When rebuilding makefiles inherit
2355 dontcare flag from a target that triggered update.
2357 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2359 * variable.c (initialize_file_variables): Mark pattern-specific
2360 variable as a per-target and copy export status.
2362 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2364 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2366 * implicit.c (pattern_search): When considering an implicit rule's
2367 prerequisite check that it is actually a target rather then
2368 just an entry in the file hashtable.
2370 2004-09-21 Paul D. Smith <psmith@gnu.org>
2372 * read.c (readstring): Fix some logic errors in backslash handling.
2373 (eval): Remove some unnecessary processing in buffer handling.
2374 (record_target_var): Assert that parse_variable_definition() succeeded.
2375 Reported by: Markus Mauhart <qwe123@chello.at>.
2377 * misc.c: Removed the sindex() function. All instances of this
2378 function were trivially replaceable by the standard strstr()
2379 function, and that function will always have better (or certainly
2380 no worse) performance than the very simple-minded algorithm
2381 sindex() used. This can matter with complex makefiles.
2382 * make.h: Remove the prototype for sindex().
2383 * function.c (subst_expand): Convert sindex() call to strstr().
2384 This means we no longer need to track the TLEN value so remove that.
2385 (func_findstring): Convert sindex() to strstr().
2386 * commands.c (chop_commands): Convert sindex() calls to strstr().
2387 Suggested by: Markus Mauhart <qwe123@chello.at>.
2389 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2390 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2391 If SHELL is set to CMD.EXE then assume it's batch-mode and
2392 non-unixy. I wrote the code differently from the patch, though,
2393 to make it safer. This also resolves bug #9174.
2395 2004-09-20 Paul D. Smith <psmith@gnu.org>
2397 * expand.c (variable_expand_string): Modify to invoke
2398 patsubst_expand() instead of subst_expand(); the latter didn't
2399 handle suffix patterns correctly.
2400 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2401 was used only from variable_expand_string() and is no longer used
2403 (func_subst): Ditto, on call to subst_expand().
2404 (patsubst_expand): Require the percent pointers to point to the
2405 character after the %, not to the % itself.
2406 * read.c (record_files): New call criteria for patsubst_expand().
2407 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2408 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2410 2004-09-19 Paul D. Smith <psmith@gnu.org>
2412 * function.c (subst_expand): Fix a check in by_word: look for a
2413 previous blank if we're beyond the beginning of the string, not
2414 the beginning of the word.
2415 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2417 2004-05-16 Paul D. Smith <psmith@gnu.org>
2419 * remake.c (update_goal_chain): Change the argument specifying
2420 whether we're rebuilding makefiles to be a global variable,
2421 REBUILDING_MAKEFILES.
2422 (complain): Extract the code that complains about no rules to make
2423 a target into a separate function.
2424 (update_file_1): If we tried to rebuild a file during the makefile
2425 rebuild phase and it was dontcare, then no message was printed.
2426 If we then try to build the same file during the normal build,
2427 print a message this time.
2428 (remake_file): Don't complain about un-remake-able files when
2429 we're rebuilding makefiles.
2431 2004-05-11 Paul D. Smith <psmith@gnu.org>
2433 * job.c (construct_command_argv_internal): OS/2 patches from
2434 Andreas Buening <andreas.buening@nexgo.de>.
2436 2004-05-10 Paul D. Smith <psmith@gnu.org>
2438 * remake.c (update_file): Don't walk the double-colon chain unless
2439 this is a double-colon rule. Fix suggested by Boris Kolpackov
2440 <boris@kolpackov.net>.
2442 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2443 * readme.vms: New section describing OpenVMS support and issues.
2444 * default.c (default_variables): Add support for IA64.
2445 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2446 without some privilege aborts make with the error
2447 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2448 pressing Ctrl+Y and the input device is no terminal. The change
2449 catches this error and just continues.
2451 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2453 2004-04-25 Paul D. Smith <psmith@gnu.org>
2455 * commands.c (set_file_variables): Set $< properly in the face of
2456 order-only prerequisites.
2457 Patch from Boris Kolpackov <boris@kolpackov.net>
2459 2004-04-21 Bob Byrnes <byrnes@curl.com>
2461 * main.c (main): Notice failures to remake makefiles.
2463 2004-03-28 Paul D. Smith <psmith@gnu.org>
2465 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2467 * job.c: No default shell for RISC OS.
2468 (load_too_high): Hard-code the return to 1.
2469 (construct_command_argv_internal): No sh_chars or sh_cmds.
2470 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2472 2004-03-20 Paul D. Smith <psmith@gnu.org>
2474 * variable.c (do_variable_definition): Don't append from the
2475 global set if a previous non-appending target-specific variable
2476 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2479 * expand.c (reference_variable): Don't give up on variables with
2480 no value that have the target-specific append flag set: they might
2481 have a value after all. Reported by Oliver Schmidt
2482 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2483 <nikulin@dx1cmd.inp.nsk.su>.
2485 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2486 refer to absolute pathnames in directories that don't exist: some
2487 portion of the makefile could create those directories before we
2488 match the pattern. Fixes bugs #775 and #108.
2490 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2492 * main.c (main): Free makefile_mtimes if we have any.
2493 * README.W32.template: Update documentation for the current status
2494 of the MS-Windows port.
2495 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2496 environment variable is sometimes already defined which causes the
2498 * main.c (debug_signal_handler): Only define this function if
2499 SIGUSR1 is available.
2501 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2503 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2504 * README.OS2.template: Documentation updates.
2505 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2506 link line for safety.
2507 * maintMakefile (build.sh.in): Remove an extraneous ")".
2508 * job.c (child_execute_job): Close saved FDs.
2509 * job.c (exec_command) [OS/2]: exec_command(): If the command
2510 can't be exec'ed and if the shell is not Unix-sh, then try again
2511 with argv = { "cmd", "/c", ... }. Normally, this code is never
2512 reached for the cmd shell unless the command really doesn't exist.
2513 (construct_command_argv_internal) [OS/2]: The code for cmd
2514 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2515 The CMD builtin commands are case insensitive so use strcasecmp().
2517 2004-03-19 Paul D. Smith <psmith@gnu.org>
2519 * read.c (do_define): Re-order line counter increment so the count
2520 is accurate (we were losing one line per define). Reported by
2521 Dave Yost <Dave@Yost.com>.
2523 2004-03-06 Paul D. Smith <psmith@gnu.org>
2525 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2527 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2528 * misc.c (message,error,fatal): Ditto.
2529 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2530 * config.h.W32.template: Ditto.
2531 * config.h-vms.template: Ditto.
2532 * config.ami.template: Ditto.
2534 2004-03-04 Paul D. Smith <psmith@gnu.org>
2536 * README.template: Add a note about broken /bin/sh on SunOS
2537 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2539 * misc.c (message, error, fatal): Don't use "..." if we're using
2540 varargs. ansi2knr should handle this but it doesn't work: it
2541 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2542 done. On many systems (SunOS for example) va_dcl is a #define.
2543 So, force the use of the non-"..." version on pre-ANSI compilers.
2545 * maintMakefile (sign-dist): Create some rules to help automate
2546 the new GNU ftp upload method.
2548 2004-02-24 Paul D. Smith <psmith@gnu.org>
2550 * config.h.W32.template: Add HAVE_STDARG_H
2551 * config.h-vms.template: Ditto.
2552 * config.ami.template: Ditto.
2554 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2556 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2557 * build_w32.bat: Remove extra "+".
2559 2004-02-23 Paul D. Smith <psmith@gnu.org>
2561 * make.h: Create an UNUSED macro to mark unused parameters.
2562 * (many): Clean up warnings by applying UNUSED, fixing
2563 signed/unsigned incompatibilities, etc.
2565 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2567 * filedef.h: Name the command_state enumeration.
2568 * file.c (set_command_state): Use the enumeration in the function
2571 * configure.in: Explicitly set SET_MAKE to empty, to disable
2572 MAKE=make even when no make already exists. Fix bug #3823.
2574 2004-02-22 Paul D. Smith <psmith@gnu.org>
2576 * maintMakefile: Perl script to clean up all non-CVS files. Use
2577 it on all the subdirectories for the cvs-clean target.
2579 * main.c (decode_switches): Require non-empty strings for all our
2580 string command-line options. Fixes Debian bug # 164165.
2582 * configure.in: Check for stdarg.h and varargs.h.
2583 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2584 for printing messages.
2585 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2590 A number of patches for OS/2 support from Andreas Buening
2591 <andreas.buening@nexgo.de>:
2593 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2594 disable the SIGCHLD handler.
2595 (reap_children) [OS/2]: Remove special handling of job_rfd.
2596 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2597 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2598 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2599 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2600 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2603 2004-02-21 Paul D. Smith <psmith@gnu.org>
2605 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2606 <mail@kristov.de> reports that if process_begin() fails we don't
2607 handle the error condition correctly in all cases.
2608 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2609 to have a newline on the message.
2611 * job.c (construct_command_argv_internal): Add "test" to UNIX
2612 sh_cmds[]. Fixes Savannah bug # 7606.
2614 2004-02-04 Paul D. Smith <psmith@gnu.org>
2616 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2617 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2618 Hartmut Becker <Hartmut.Becker@hp.com>.
2620 2004-01-21 Paul D. Smith <psmith@gnu.org>
2622 * job.c (load_too_high): Implement an algorithm to control the
2623 "thundering herd" problem when using -l to control job creation
2624 via the load average. The system only recomputes the load once a
2625 second but we can start many jobs in a second. To solve this we
2626 keep track of the number of jobs started in the last second and
2627 apply a weight to try to guess what a correct load would be.
2628 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2629 Also fixes bug #4693.
2630 (reap_children): Decrease the job count for this second.
2631 (start_job_command): Increase the job count for this second.
2633 * read.c (conditional_line): Expand the text after ifn?def before
2634 checking to see if it's a single word. Fixes bug #7257.
2636 2004-01-09 Paul D. Smith <psmith@gnu.org>
2638 * file.c (print_file): Recurse to print all targets in
2639 double-colon rules. Fixes bug #4518, reported (with patch) by
2640 Andrew Chatham <chatham@google.com>.
2642 2004-01-07 Paul D. Smith <psmith@gnu.org>
2644 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2645 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2646 AC_FUNC_SETVBUF_REVERSED.
2648 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2649 (MAKE Variable): Fix Savannah bug #4898.
2651 * job.c (construct_command_argv_internal): Add "!" to the list of
2652 shell escape chars. POSIX sh allows it to appear before a
2653 command, to negate the exit code. Fixes bug #6404.
2655 * implicit.c (pattern_search): When matching an implicit rule,
2656 remember which dependencies have the ignore_mtime flag set.
2657 Original fix provided in Savannah patch #2349, by Benoit
2658 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2660 2003-11-22 Paul D. Smith <psmith@gnu.org>
2662 * README.W32.template (Outputs): Clarification on -j with
2663 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2666 2003-11-02 Paul D. Smith <psmith@gnu.org>
2668 * function.c (func_if): Strip all the trailing whitespace from the
2669 condition, then don't expand it. Fixed bug # 5798.
2671 * expand.c (recursively_expand_for_file): If we're expanding a
2672 variable with no file context, then use the variable's context.
2675 2003-10-21 Paul D. Smith <psmith@gnu.org>
2677 * main.c (log_working_directory): Add newlines to printf()s.
2679 * README.cvs: Add a note to ignore warnings during autoreconf.
2681 * maintMakefile (po_repo): Set a new URL for PO file updates.
2682 (get-config/config.guess get-config/config.sub): Get these files
2683 from the Savannah config project instead of ftp.gnu.org.
2685 2003-10-05 Paul Eggert <eggert@twinsun.com>
2687 * main.c (main): Avoid potential subscript error if environ has
2690 2003-08-22 Paul D. Smith <psmith@gnu.org>
2692 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2693 systems which don't yet implement the C89 standard :-/.
2695 2003-07-18 Paul D. Smith <psmith@gnu.org>
2697 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2698 [WINDOWS32]: Initialize hash.
2700 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2702 * dir.c (read_dirstream): Provide a workaround for broken versions of
2703 the MinGW dirent structure.
2705 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2707 * w32/include/dirent.h: Add __MINGW32__ filter.
2709 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2711 * make.h: Add global declaration of *make_host.
2712 * main.c (print_usage): Remove local declaration of *make_host.
2713 (print_version): Display "This program built for ..." after Copyright
2716 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2718 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2719 execution of "makeinfo --html make.texi".
2721 2003-04-30 Paul D. Smith <psmith@gnu.org>
2723 * build.template: Make some changes to maybe allow this script to
2724 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2726 * README.OS2.template: New file for OS/2 support. Original
2727 contributed by Andreas Buening.
2728 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2731 2003-04-19 Paul D. Smith <psmith@gnu.org>
2733 Fix bug #1405: allow a target to match multiple pattern-specific
2736 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2737 variable.c, where they've always belonged.
2738 * rule.h: Move the prototypes and struct pattern_var as well.
2739 * variable.c (initialize_file_variables): Invoke
2740 lookup_pattern_var() in a loop, until no more matches are found.
2741 If a match is found, create a new variable set for the target's
2742 pattern variables. Then merge the contents of each matching
2743 pattern variable set into the target's pattern variable set.
2744 (lookup_pattern_var): Change this function to be usable
2745 in a loop. It takes a starting position: if NULL, start at the
2746 beginning; if non-NULL, start with the pattern variable after that
2747 position, and return the next matching pattern.
2748 (create_pattern_var): Create a unique instance of
2749 pattern-specific variables for every definition in the makefile.
2750 Don't combine the same pattern together. This allows us to
2751 process the variable handling properly even when the same pattern
2752 is used multiple times.
2753 (parse_variable_definition): New function: break out the parsing
2754 of a variable definition line from try_variable_definition.
2755 (try_variable_definition): Call parse_variable_definition to
2757 (print_variable_data_base): Print out pattern-specific variables.
2758 * variable.h (struct variable): Remember when a variable is
2759 conditional. Also remember its flavor.
2760 (struct pattern_var): Instead of keeping a variable set, we just
2761 keep a single variable for each pattern.
2762 * read.c (record_target_var): Each pattern variable contains only a
2763 single variable, not a set, so create it properly.
2764 * doc/make.texi (Pattern-specific): Document the new behavior.
2766 2003-04-17 Paul D. Smith <psmith@gnu.org>
2768 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2769 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2770 file/directory naming rules for VMS so I can't tell whether this
2773 2003-04-09 Paul D. Smith <psmith@gnu.org>
2775 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2776 DOS-style pathnames: backslash separators and drive specifiers.
2778 2003-03-28 Paul D. Smith <psmith@gnu.org>
2780 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2781 the intermediate flag on all targets. Fixes bug #2515.
2783 2003-03-24 Paul D. Smith <psmith@gnu.org>
2785 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2786 Upgrade to autoconf 2.57 and automake 1.7.3.
2788 * job.c: More OS/2 changes from Andreas Buening.
2790 * file.c (print_file): Fix variable initialization.
2793 * remake.c (notice_finished_file):
2795 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2796 some calls (like readdir()) return NULL in valid situations
2797 without resetting errno. Fixes bug #2846.
2799 2003-02-25 Paul D. Smith <psmith@gnu.org>
2801 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2803 * job.c (_is_unixy_shell) [OS/2]: New function.
2804 Set default shell to /bin/sh.
2805 (reap_children): Close the job_rfd pipe here since we don't use a
2807 (set_child_handler_action_flags): define this to empty on OS/2.
2808 (start_job_command): Close the jobserver pipe and use
2809 child_execute_job() instead of fork/exec.
2810 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2811 rather than exec'ing, then reconfigure stdin/stdout.
2812 (exec_command): Rewrite to use spawn instead of exec. Return the
2815 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2816 in DOS. Handle the TEMP environment variable as in DOS. Don't
2817 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2818 use -j in DOS mode. Use child_execute_job() instead of
2821 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2824 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2825 prototypes that return values.
2827 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2829 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2830 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2832 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2835 2003-02-24 Paul D. Smith <psmith@gnu.org>
2837 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2838 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2839 (child_execute_job) [VMS]: Handle error status properly.
2840 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2842 * function.c (func_shell): Use EINTRLOOP() while reading from the
2843 subshell pipe (Fixes bug #2502).
2844 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2846 * main.c (main): Ditto.
2848 2003-01-30 Paul D. Smith <psmith@gnu.org>
2850 * read.c (eval): eval() was not fully reentrant, because the
2851 collapsed buffer was static. Change it to be an automatic
2852 variable so that eval() can be invoked recursively.
2854 (eval): Apply patch # 1022: fix memory reference error on long
2855 target-specific variable lines.
2856 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2858 * function.c (check_numeric): Combine the is_numeric() function
2859 into this function, since it's only called from one place.
2860 Constify this function. Have it print the incorrect string in the
2861 error message. Fixes bug #2407.
2862 (strip_whitespace): Constify.
2863 (func_if): Constify.
2864 * expand.c (expand_argument): Constify.
2866 2003-01-29 Paul D. Smith <psmith@gnu.org>
2868 Fix bug # 2169, also reported by other people on various systems.
2870 * make.h: Some systems, such as Solaris and PTX, do not fully
2871 implement POSIX-compliant SA_RESTART functionality; important
2872 system calls like stat() and readdir() can still fail with EINTR
2873 even if SA_RESTART has been set on the signal handler. So,
2874 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2875 EINTR for system calls which return -1 or 0 (NULL), respectively,
2877 Also, remove the old atomic_stat()/atomic_readdir() and
2878 HAVE_BROKEN_RESTART handling.
2880 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2882 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2883 * remake.c (touch_file): Ditto.
2885 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2886 * read.c (construct_include_path): Ditto.
2887 * remake.c (name_mtime): Ditto.
2888 * vpath.c (selective_vpath_search): Ditto.
2889 * dir.c (find_directory): Ditto.
2890 (local_stat): Ditto.
2891 (find_directory): Use ENULLLOOP() to wrap opendir().
2892 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2894 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2895 atomic_readdir() handling.
2897 2003-01-22 Paul D. Smith <psmith@gnu.org>
2899 * function.c (func_call): Fix Bug #1744. If we're inside a
2900 recursive invocation of $(call ...), mask any of the outer
2901 invocation's arguments that aren't used by this one, so that this
2902 invocation doesn't "inherit" them accidentally.
2904 2002-12-05 Paul D. Smith <psmith@gnu.org>
2906 * function.c (subst_expand): Valery Khamenia reported a
2907 pathological performance hit when doing substitutions on very
2908 large values with lots of words: turns out we were invoking
2909 strlen() a ridiculous number of times. Instead of having each
2910 call to sindex() call strlen() again, keep track of how much of
2911 the text we've seen and pass the length to sindex().
2913 2002-11-19 Paul D. Smith <psmith@gnu.org>
2915 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2918 2002-11-16 Paul D. Smith <psmith@gnu.org>
2920 * NMakefile.template (OBJS): Add hash.c object file.
2921 * SMakefile.template (srcs): Ditto.
2922 * Makefile.ami (objs): Ditto.
2923 * build_w32.bat: Ditto.
2925 * Makefile.DOS.template: Remove extra dependencies.
2927 2002-10-25 Paul D. Smith <psmith@gnu.org>
2929 * expand.c (install_variable_buffer): New function. Install a new
2930 variable_buffer context and return the previous one.
2931 (restore_variable_buffer): New function. Free the current
2932 variable_buffer context and put a previously saved one back.
2933 * variable.h: Prototypes for {install,restore}_variable_buffer.
2934 * function.c (func_eval): Push a new variable_buffer context
2935 before we eval, then restore the old one when we're done.
2938 * read.c (install_conditionals): New function. Install a new
2939 conditional context and return the previous one.
2940 (restore_conditionals): New function. Free the current
2941 conditional context and put a previously saved one back.
2942 (eval): Use the {install,restore}_conditionals for "include"
2944 (eval_buffer): Use {install,restore}_conditionals to preserve the
2945 present conditional state before we evaluate the buffer.
2948 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2950 (Recursion): Add a variable index entry for CURDIR.
2952 * README.cvs: Update to appropriate versions.
2953 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2954 don't need to copy loadavg.c: automake is smart enough to create
2955 it for me. Still have a bug in automake related to ansi2knr tho.
2957 2002-10-14 Paul D. Smith <psmith@gnu.org>
2959 * remake.c (notice_finished_file): Only touch targets if they have
2960 at least one command (as per POSIX). Resolve Bug #1418.
2962 * *.c: Convert to using ANSI C-style function definitions.
2963 * Makefile.am: Enable the ansi2knr feature of automake.
2964 * configure.in: ditto.
2966 2002-10-13 Paul D. Smith <psmith@gnu.org>
2968 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2969 for automatic variable values like $^, etc. In the case of very
2970 large lists of prerequisites this causes problems. Instead reuse
2971 a static buffer (resizeable) for each variable.
2973 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2974 target-specific variable definitions. Check for it and set an
2976 (record_target_var): Set the export field to v_export if the
2977 "exported" flag is set.
2978 * doc/make.texi (Target-specific): Document the ability to use
2981 * doc/make.texi: Change the name of the section on automatic
2982 variables from "Automatic" to "Automatic Variables". Added text
2983 clarifying the scope of automatic variables.
2985 2002-10-04 Paul D. Smith <psmith@gnu.org>
2987 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2989 (record_files): Ditto.
2991 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2992 the search for the '=' to only within the enclosing parens.
2994 2002-10-03 Paul D. Smith <psmith@gnu.org>
2996 Version 3.80 released.
2998 * dir.c: Change hash functions to use K&R function definition style.
2999 * function.c: Ditto.
3001 * variable.c: Ditto.
3003 Update to automake 1.7.
3005 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3006 (pdf): Remove this target as automake now provides one.
3008 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3010 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3012 * makefile.com: Updates for GNU make 3.80.
3013 * makefile.vms: Ditto.
3015 2002-09-23 Paul D. Smith <psmith@gnu.org>
3017 * read.c (enum make_word_type): Remove w_comment.
3018 (get_next_mword): Don't treat comment characters as special; where
3019 this function is used we will never see a comment (it's stripped
3020 before we get here) and treating comments specially means that
3021 targets like "foo\#bar" aren't handled properly.
3023 2002-09-18 Paul D. Smith <psmith@gnu.org>
3025 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3027 * read.c (eval): Expansion of arguments to export/unexport was
3028 ignoring all arguments after the first one. Change the algorithm
3029 to expand the whole line once, then parse the results.
3031 2002-09-17 Paul D. Smith <psmith@gnu.org>
3033 Fix Bug #940 (plus another bug I found while looking at this):
3035 * read.c (record_target_var): enter_file() will add a new entry if
3036 it's a double-colon target: we don't want to do that in this
3037 situation. Invoke lookup_file() and only enter_file() if it does
3038 not already exist. If the file we get back is a double-colon then
3039 add this variable to the "root" double-colon target.
3041 * variable.c (initialize_file_variables): If this file is a
3042 double-colon target but is not the "root" target, then initialize
3043 the root and make the root's variable list the parent of our
3046 2002-09-13 Paul D. Smith <psmith@gnu.org>
3048 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3050 * hash.c (round_up_2): Get rid of a warning.
3052 2002-09-12 Paul D. Smith <psmith@gnu.org>
3054 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3055 so it doesn't complain about getloadavg.c.
3057 * commands.c (set_file_variables): Make sure we always alloca() at
3058 least 1 character for the value of $? (for '\0').
3060 2002-09-11 Paul D. Smith <psmith@gnu.org>
3062 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3063 macro to use RESULT instead of the incorrect _RESULT_.
3065 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3066 and atomic_readdir(). We need to #include dirent.h to get this to
3068 * misc.c (atomic_readdir): Fix typos.
3070 2002-09-10 Paul D. Smith <psmith@gnu.org>
3072 * read.c (eval): Expand variable lists given to export and
3073 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3074 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3076 * doc/make.texi (Variables/Recursion): Document this.
3077 (Conditional Syntax): And here.
3079 2002-09-09 Paul D. Smith <psmith@gnu.org>
3081 * configure.in: Check for memmove().
3083 2002-09-07 Paul D. Smith <psmith@gnu.org>
3085 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3086 Michael Sterrett <msterret@coat.com> reports that while it has
3087 SA_RESTART, it does not work properly.
3089 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3090 that invokes stat() and loops to do it again if it returns EINTR.
3091 (atomic_readdir): Ditto, with readdir().
3093 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3094 and readdir() to atomic_stat() and atomic_readdir().
3096 2002-09-04 Paul D. Smith <psmith@gnu.org>
3098 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3099 reports that GNU make sometimes doesn't recognize that targets can
3100 be made, when directories can be created as prerequisites. He
3101 reports that changing the order of predicates in the DEP->changed
3102 flag test so that lookup_file() is always performed, solves this
3105 2002-08-08 Paul D. Smith <psmith@gnu.org>
3107 * configure.in: Require a newer version of gettext.
3109 * misc.c (perror_with_name): Translate the format string (for
3110 right-to-left language support).
3111 (pfatal_with_name): Ditto.
3113 * main.c: Create a static array of strings to store the usage
3114 text. This is done to facilitate translations.
3115 (struct command_switch): Remove argdesc and description fields.
3116 (switches): Remove values for obsolete fields.
3117 (print_usage): Print each element of the usage array.
3119 * hash.c: Change function definitions to be K&R style.
3121 2002-08-02 Paul D. Smith <psmith@gnu.org>
3123 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3124 this one because it's too hard to get right. We'll look at it for
3126 * main.c (main): Don't create the .TARGETS variable.
3127 * variable.c (handle_special_var): Don't handle .TARGETS.
3129 2002-08-01 Paul D. Smith <psmith@gnu.org>
3131 * main.c (switches): Add a new option, -B (--always-make). If
3132 specified, make will rebuild all targets that it encounters even
3133 if they don't appear to be out of date.
3134 (always_make_flag): New flag.
3135 * make.h: Extern always_make_flag.
3136 * remake.c (update_file_1): Check always_make_flag; if it's set we
3137 will always rebuild any target we can, even if none of its
3138 prerequisites are newer.
3141 * doc/make.texi (Shell Function): Make it clear that make
3142 variables marked as "export" are not passed to instances of the
3145 Add new introspection variable .VARIABLES and .TARGETS.
3147 * variable.c (handle_special_var): New function. If the variable
3148 reference passed in is "special" (.VARIABLES or .TARGETS),
3149 calculate the new value if necessary. .VARIABLES is handled here:
3150 walk through the hash of defined variables and construct a value
3151 which is a list of the names. .TARGETS is handled by
3152 build_target_list().
3153 (lookup_variable): Invoke handle_special_var().
3154 * file.c (build_target_list): Walk through the hask of known files
3155 and construct a list of the names of all the ones marked as
3157 * main.c (main): Initialize them to empty (and as simple variables).
3158 * doc/make.texi (Special Variables): Document them.
3159 * NEWS: Mention them.
3161 * variable.h (struct variable): Add a new flag "exportable" which
3162 is true if the variable name is valid for export.
3163 * variable.c (define_variable_in_set): Set "exportable" when a new
3164 variable is defined.
3165 (target_environment): Use the "exportable" flag instead of
3166 re-checking the name here... an efficiency improvement.
3168 2002-07-31 Paul D. Smith <psmith@gnu.org>
3170 * config.h-vms.template: Updates to build on VMS. Thanks to
3171 Brian_Benning@aksteel.com for helping verify the build.
3172 * makefile.com: Build the new hash.c file.
3173 * hash.h: Use strcpmi(), not stricmp(), in the
3174 HAVE_CASE_INSENSITIVE_FS case.
3176 2002-07-30 Paul D. Smith <psmith@gnu.org>
3178 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3179 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3180 Reported by <Brian_Benning@aksteel.com>.
3182 2002-07-10 Paul D. Smith <psmith@gnu.org>
3184 * variable.c (pop_variable_scope): Remove variable made unused by
3185 new hash infrastructure.
3186 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3187 comparisons as well as name comparisons.
3188 * variable.h: Add a prototype for new hash_init_function_table().
3189 * file.c (lookup_file): Remove variables made unused by new hash
3191 * dir.c (directory_contents_hash_2): Missing return of hash value.
3192 (dir_contents_file_exists_p): Remove variables made unused by new
3193 hash infrastructure.
3196 Installed Greg McGary's integration of the hash functions from the
3197 GNU id-utils package:
3199 2002-07-10 Greg McGary <greg@mcgary.org>
3201 * scripts/functions/filter-out: Add literals to to the
3202 pattern space in order to add complexity, and trigger
3203 use of an internal hash table. Fix documentation strings.
3204 * scripts/targets/INTERMEDIATE: Reverse order of files
3205 passed to expected `rm' command.
3207 2002-07-10 Greg McGary <greg@mcgary.org>

3299 2002-07-10 Paul D. Smith <psmith@gnu.org>
3301 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3302 prerequisite list. A real SysV make will expand the entire
3303 prerequisites list _twice_: we don't do that as it's a big
3304 backward-compatibility problem. We only replace those specific
3307 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3308 references left in the list of prerequisites. Check for .POSIX as
3309 we record targets, so we can disable non-POSIX behavior while
3310 reading makefiles as well as running them.
3311 (eval): Check the prerequisite list to see if we have anything
3312 that looks like a SysV prerequisite variable reference.
3314 2002-07-09 Paul D. Smith <psmith@gnu.org>
3316 * doc/make.texi (Prerequisite Types): Add a new section describing
3317 order-only prerequisites.
3319 * read.c (uniquize_deps): If we have the same file as both a
3320 normal and order-only prereq, get rid of the order-only prereq,
3321 since the normal one supersedes it.
3323 2002-07-08 Paul D. Smith <psmith@gnu.org>
3325 * AUTHORS: Added Greg McGary to the AUTHORS file.
3326 * NEWS: Blurbed order-only prerequisites.
3327 * file.c (print_file): Show order-only deps properly when printing
3330 * maintMakefile: Add "update" targets for wget'ing the latest
3331 versions of various external files. Taken from Makefile.maint in
3334 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3335 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3337 2002-07-07 Paul D. Smith <psmith@gnu.org>
3339 * po/*.po: Remove. We'll use wget to retrieve them at release
3342 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3343 rather than a shell you get an exception. Make sure we look up
3344 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3346 * remake.c (notice_finished_file): Fix handling of -t flag.
3347 Patch provided by Henning Makholm <henning@makholm.net>.
3349 * implicit.c (pattern_search): Some systems apparently run short
3350 of stack space, and using alloca() in this function caused an
3351 overrun. I modified it to use xmalloc() on the two variables
3352 which seemed like they might get large. Fixes Bug #476.
3354 * main.c (print_version): Update copyright notice to conform with
3356 (print_usage): Update help output.
3358 * function.c (func_eval): Create a new make function, $(eval
3359 ...). Expand the arguments, put them into a buffer, then invoke
3360 eval_buffer() on the resulting string.
3361 (func_quote): Create a new function, $(quote VARNAME). Inserts
3362 the value of the variable VARNAME without expanding it any
3365 * read.c (struct ebuffer): Change the linebuffer structure to an
3366 "eval buffer", which can be either a file or a buffer.
3367 (eval_makefile): Move the code in the old read_makefile() which
3368 located a makefile into here: create a struct ebuffer with that
3369 information. Have it invoke the new function eval() with that
3371 (eval_buffer): Create a new function that creates a struct ebuffer
3372 that holds a string buffer instead of a file. Have it invoke
3373 eval() with that ebuffer.
3374 (eval): New function that contains the guts of the old
3375 read_makefile() function: this function parses makefiles. Obtains
3376 data to parse from the provided ebuffer. Some modifications to
3377 make the flow of the function cleaner and clearer. Still could
3378 use some work here...
3379 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3380 contents of the define/endef variable from the ebuffer.
3381 (readstring): Read the next line from a string-style ebuffer.
3382 (readline): Read the next line from an ebuffer. If it's a string
3383 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3386 * dep.h (eval_buffer): Prototype eval_buffer();
3388 * variable.c (do_variable_definition): Make sure that all
3389 non-target-specific variables are registered in the global set.
3390 If we're invoked from an $(eval ...) we might be inside a $(call
3391 ...) or other function which has pushed a variable scope; we still
3392 want to define our variables from evaluated makefile code in the
3395 2002-07-03 Greg McGary <greg@mcgary.org>
3397 * dep.h (struct dep) [ignore_mtime]: New member.
3398 [changed]: convert to a bitfield.
3399 * implicit.c (pattern_search): Zero ignore_mtime.
3400 * main.c (main, handle_non_switch_argument): Likewise.
3401 * rule.c (convert_suffix_rule): Likewise.
3402 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3403 (read_makefile): Parse '|' in prerequisite list.
3404 (uniquize_deps): Consider ignore_mtime when comparing deps.
3405 * remake.c (update_file_1, check_dep): Don't force remake for
3406 dependencies that have d->ignore_mtime.
3407 * commands.c (FILE_LIST_SEPARATOR): New constant.
3408 (set_file_variables): Don't include a
3409 prerequisite in $+, $^ or $? if d->ignore_mtime.
3412 2002-06-18 Paul D. Smith <psmith@gnu.org>
3414 * make.texinfo: Updates for next revision. New date/rev/etc.
3415 Recreate all Info menus. Change license on the manual to the GNU
3416 Free Documentation License. A number of typos.
3417 (Variables Simplify): Don't use "-" before it's defined.
3418 (Automatic Prerequisites): Rewrite the target example to work
3419 properly if the compile fails. Remove incorrect comments about
3420 how "set -e" behaves.
3421 (Text Functions): Move the "word", "wordlist", "words", and
3422 "firstword" functions here, from "File Name Functions".
3423 * make-stds.texi: Update from latest GNU version.
3424 * fdl.texi: (created) Import the latest GNU version.
3426 2002-06-06 Paul D. Smith <psmith@gnu.org>
3428 * variable.c (do_variable_definition): New function: extract the
3429 part of try_variable_definition() that actually sets the value
3430 into a separate function.
3431 (try_variable_definition): Call do_variable_definition() after
3432 parsing the variable definition string.
3433 (define_variable_in_set): Make the name argument const.
3435 * variable.h (enum variable_flavor): Make public.
3436 (do_variable_definition): Create prototype.
3438 * read.c (read_all_makefiles): Create a new built-in variable,
3440 (read_makefile): Add each makefile read in to this variable value.
3442 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3444 * Makefile.DOS.template: Tweak according to changes in the
3445 distribution. Add back the dependencies of *.o files.
3447 * configh.dos.template: Synchronize with config.h.in.
3449 2002-05-09 Paul D. Smith <psmith@gnu.org>
3451 * file.c (file_timestamp_now): Use K&R function declaration.
3453 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3454 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3455 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3456 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3457 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3458 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3459 nlist.n_name is a pointer rather than an array.
3461 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3462 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3463 * configure.in: Use it instead of the old version.
3465 * main.c (main): Prefer setvbuf() to setlinebuf().
3467 2002-05-08 Paul D. Smith <psmith@gnu.org>
3469 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3470 (loadavg_LDADD): Ditto.
3472 2002-04-29 Paul D. Smith <psmith@gnu.org>
3474 * expand.c (recursively_expand_for_file): Rename
3475 recursively_expand() to recursively_expand_for_file() and provide
3476 an extra argument, struct file. If the argument is provided, set
3477 the variable scope to that of the file before expanding.
3478 * variable.h (recursively_expand): Make this a macro that invokes
3479 recursively_expand_for_file() with a NULL file pointer.
3480 * variable.c (target_environment): Call the renamed function and
3481 provide the current file context.
3482 Fixes Debian bug #144306.
3484 2002-04-28 Paul D. Smith <psmith@gnu.org>
3486 Allow $(call ...) user-defined variables to be self-referencing
3487 without throwing an error. Allows implementation of transitive
3488 closures, among other possibly useful things.
3489 Requested by: Philip Guenther <guenther@sendmail.com>
3491 * variable.h (struct variable): Add a new field: exp_count, and
3492 new macros to hold its size and maximum value.
3493 (warn_undefined): Make this a macro.
3494 * variable.c (define_variable_in_set): Initialize it.
3495 * expand.c (recursively_expand): If we detect recursive expansion
3496 of a variable, check the exp_count field. If it's greater than 0
3497 allow the recursion and decrement the count.
3498 (warn_undefined): Remove this (now a macro in variable.h).
3499 * function.c (func_call): Before we expand the user-defined
3500 function, modify its exp_count field to contain the maximum
3501 number of recursive calls we'll allow. After the call, reset it
3504 2002-04-21 Paul D. Smith <psmith@gnu.org>
3506 Modified to use latest autoconf (2.53), automake (1.6.1), and
3507 gettext (0.11.1). We're using gettext's new "external" support,
3508 to avoid including libintl source with GNU make.
3510 * README.cvs: New file. Explain how to build GNU make from CVS.
3512 * configure.in: Modify checking for the system glob library.
3513 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3514 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3515 etc. will manage it correctly). Set an automake conditional
3516 USE_LOCAL_GLOB to decide whether to compile the glob library.
3518 * getloadavg.c (main): Include make.h in the "TEST" program to
3521 * Makefile.am: Remove special rules for loadavg. Replace them
3522 with Automake capabilities for building extra programs.
3524 * signame.c: This file does nothing if the system provide
3525 strsignal(). If not, it implements strsignal(). If the system
3526 doesn't define sys_siglist, then we make our own; otherwise we use
3528 * signame.h: Removed.
3530 * main.c (main): No need to invoke signame_init(). Update copyright.
3532 * ABOUT-NLS: Removed.
3533 * gettext.c: Removed.
3534 * gettext.h: Get a simplified copy from the gettext package.
3536 * i18n/*.po: Moved to po/.
3539 * config/*: Created. Contains package configuration helper files.
3540 * config.guess, config.sub: Moved to config directory.
3542 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3543 Rework to use new-style autoconf features. Use the "external"
3544 mode for gettext. Make the build.sh config file conditional on
3545 whether build.sh.in exists, to avoid autoconf errors.
3546 * acinclude.m4: Removed almost all macros as being obsolete.
3547 Rewrote remaining macros to use AC_DEFINE.
3548 * acconfig.h: Removed.
3550 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3551 conditional to handle customs support. Remove special handling
3554 2002-04-20 Paul D. Smith <psmith@gnu.org>
3556 * function.c (func_call): Don't mark the argument variables $1,
3557 etc. as recursive. They've already been fully expanded so
3558 there's no need to do it again, and doing so strips escaped $'s.
3559 Reported by Sebastian Glita <glseba@yahoo.com>.
3561 * remake.c (notice_finished_file): Walk through double-colon
3562 entries via the prev field, not the next field!
3563 Reported by Greg McGary <greg@mcgary.org>.
3565 * main.c (main): If the user specifies -q and asks for a specific
3566 target which is a makefile, we got an assert. In that case it
3567 turns out we should continue normally instead.
3569 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3571 * i18n/he.po: Installed a new translation.
3573 2002-01-07 Paul D. Smith <psmith@gnu.org>

3579 * i18n/ja.po: Installed an updated translation.
3581 2001-09-06 Paul Eggert <eggert@twinsun.com>
3583 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3584 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3586 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3588 (main): Get rid of any avoidable limit on stack size.
3590 2001-09-04 Paul D. Smith <psmith@gnu.org>

3594 2001-08-03 Paul D. Smith <psmith@gnu.org>
3596 * i18n/fr.po: Installed an updated translation.
3597 Resolves Debian bug #106720.
3599 2001-06-13 Paul D. Smith <psmith@gnu.org>

3604 2001-06-11 Paul D. Smith <psmith@gnu.org>
3606 * i18n/ko.po: Installed a new translation.
3608 2001-05-06 Paul D. Smith <psmith@gnu.org>
3610 Modify the EINTR handling.
3612 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3613 the way in which we manage the file descriptor/signal handler race
3614 trap to be more efficient.
3616 2001-05-06 Paul Eggert <eggert@twinsun.com>
3618 Restart almost all system calls that are interrupted, instead
3619 of worrying about EINTR. The lone exception is the read() for
3622 * configure.in (HAVE_SA_RESTART): New macro.
3623 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3624 * main.c (main): Use SA_RESTART instead of the old,
3625 nonstandard SA_INTERRUPT.
3627 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3628 * main.c (bsd_signal): New function or macro,
3629 if the implementation doesn't supply it.
3630 (The bsd_signal function will be in POSIX 1003.1-200x.)
3631 (HANDLESIG): Remove.
3632 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3634 * make.h (EINTR_SET): Remove.
3635 (SA_RESTART): New macro.
3637 * arscan.c (ar_member_touch): Don't worry about EINTR.
3638 * function.c (func_shell): Likewise.
3639 * job.c (reap_children, free_child, new_job): Likewise.
3640 * main.c (main): Likewise.
3641 * remake.c (touch_file, name_mtime): Likewise.
3643 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3644 if fstat failed with errno!=EINTR, the error was ignored.
3646 * job.c (set_child_handler_action_flags): New function.
3647 (new_job): Use it to temporarily clear the SIGCHLD action flags
3648 while reading the token.

3652 * job.c (start_job_command): Don't add define/endef per-line flags
3653 to the top-level flags setting.
3655 2001-04-03 Paul D. Smith <psmith@gnu.org>
3657 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3658 bit on error, so check for odd return values, not non-0 return
3660 (VMS_get_member_info): Calculate the timezone differences correctly.
3661 Reported by John Fowler <jfowler@nyx.net>.
3664 2001-03-14 Paul D. Smith <psmith@gnu.org>
3666 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3667 value before invoking define_variable().
3668 Reported by John Fowler <jfowler@nyx.net>.
3670 2001-02-07 Paul D. Smith <psmith@gnu.org>
3672 * read.c (record_target_var): If we reset the variable due to a
3673 command-line variable setting overriding it, turn off the "append"
3676 2001-01-17 Paul D. Smith <psmith@gnu.org>
3678 * variable.c (lookup_variable) [VMS]: When getting values from the
3679 environment, allocate enough space for the _value_ plus escapes,
3680 not enough space for the name plus escapes :-/.
3681 Reported by John Fowler <jfowler@nyx.net>.
3683 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3684 warnings that make generates, so it doesn't look like an error.
3685 Reported by Karl Berry <karl@gnu.org>.
3688 Fix for PR/2020: Rework appended target-specific variables. I'm
3689 fairly confident this algorithm is finally correct.
3691 * expand.c (allocated_variable_append): Rewrite. Instead of
3692 expanding each appended variable then adding all the expanded
3693 strings together, we append all the unexpanded values going up
3694 through the variable set contexts, then expand the final result.
3695 This behaves just like non-target-specific appended variable
3696 values, while the old way didn't in various corner cases.
3697 (variable_append): New function: recursively append the unexpanded
3698 value of a variable, walking from the outermost variable scope to
3700 * variable.c (lookup_variable): Remove the code that looked up the
3701 variable set list if the found variable was "append". We don't
3703 (lookup_variable_in_set): Make this non-static so we can use it
3705 (try_variable_definition): Use lookup_variable_in_set() rather
3706 than faking out current_variable_set_list by hand (cleanup).
3707 * variable.h: Add a prototype for the now non-static
3708 lookup_variable_in_set().
3710 2000-11-17 Paul D. Smith <psmith@gnu.org>
3712 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3713 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3714 before throwing a fit.
3716 2000-11-17 Paul D. Smith <psmith@gnu.org>
3718 * read.c (readline): CRLF calculations had a hole, if you hit the
3719 buffer grow scenario just right. Reworked the algorithm to avoid
3720 the need for len or lastlen at all. Problem description with
3721 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3723 2000-10-24 Paul D. Smith <psmith@gnu.org>
3725 * gettext.c (SWAP): Declare this with the prototype, otherwise
3726 some systems don't work (non-32-bit? Reported for Cray T3E).
3727 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3729 2000-10-05 Paul D. Smith <psmith@gnu.org>
3731 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3732 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3734 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3736 2000-09-22 Paul D. Smith <psmith@gnu.org>
3738 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3739 parts of the real gettext.h here, and we expect to really include
3740 the real gettext.h later. If we keep this #define, it's ignored.
3742 2000-09-21 Paul D. Smith <psmith@gnu.org>
3744 * main.c (log_working_directory): Rework the text to use complete
3745 sentences, to make life simpler for the translators.
3747 2000-08-29 Paul D. Smith <psmith@gnu.org>
3749 * file.c (remove_intermediates): Print a debug message before we
3750 remove intermediate files, so the user (if she uses -d) knows
3753 2000-08-21 Paul D. Smith <psmith@gnu.org>
3755 * variable.c (try_variable_definition): Change how we handle
3756 target-specific append variable defns: instead of just setting the
3757 value, expand it as an append _but_ only within the current
3758 target's context. Otherwise we lose all but the last value if the
3759 variable is appended more than once within the current target
3760 context. Fixes PR/1831.
3762 2000-08-16 Paul D. Smith <psmith@gnu.org>
3764 * function.c (func_shell): Nul-terminate the buffer before
3765 printing an exec error message (just in case it's not!).
3766 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3768 2000-07-25 Paul D. Smith <psmith@gnu.org>
3770 * job.c (construct_command_argv_internal): Add "~" to the list of
3771 sh_chars[] which disallow optimizing out the shell call.
3773 2000-07-23 Paul Eggert <eggert@twinsun.com>
3775 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3776 supersedes --disable-nsec-timestamps.
3777 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3778 * README: Remove --disable-nsec-timestamps.
3780 * filedef.h (struct file.low_resolution_time): New member.
3781 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3782 * remake.c (update_file_1):
3783 Avoid spurious rebuilds due to low resolution time stamps,
3784 generalizing the earlier code that applied only to archive members.
3785 (f_mtime): Archive members always have low resolution time stamps.
3787 * configure.in: Remove --disable-nsec-timestamps, as this has
3788 been superseded by .LOW_RESOLUTION_TIME.
3790 2000-07-23 Paul Eggert <eggert@twinsun.com>
3792 * configure.in (enable_nsec_timestamps): Renamed from
3793 make_cv_nsec_timestamps, since enable/disable options
3794 shouldn't be cached.
3796 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3797 and Paul Eggert <eggert@twinsun.com>
3799 * file.c (file_timestamp_now):
3800 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3801 so that clock_gettime is not linked unless needed.
3803 * filedef.h (FILE_TIMESTAMP_HI_RES):
3804 Remove definition; "configure" now does this.
3806 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3807 to before high resolution file timestamp check,
3808 since that check now uses uintmax_t.
3809 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3810 high resolution file timestamps.
3811 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3812 so that we don't link in clock_gettime unnecessarily.
3814 2000-07-17 Paul D. Smith <psmith@gnu.org>
3816 * i18n/ja.po: New version of the translation file.
3818 2000-07-07 Paul D. Smith <psmith@gnu.org>
3820 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3821 the offset calculation.
3822 (name_mtime): Replace EINTR test with EINTR_SET macro.
3824 2000-07-07 Paul Eggert <eggert@twinsun.com>
3828 * remake.c (update_file_1):
3829 Avoid spurious rebuilds of archive members due to their
3830 timestamp resolution being only one second.
3831 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3832 the clock's resolution being lower than file timestamps'.
3833 When warning about future timestamps, report only the discrepancy,
3834 not the absolute value of the timestamp and the current time.
3836 * file.c (file_timestamp_now): New arg RESOLUTION.
3837 * filedef.h (file_timestamp_now): Likewise.
3838 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3840 2000-07-05 Paul D. Smith <psmith@gnu.org>
3842 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3843 to listp. Fixes PR/1793.
3845 2000-06-26 Paul Eggert <eggert@twinsun.com>
3847 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3849 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3851 * remake.c (f_mtime): Remove unused var memtime.
3853 2000-06-25 Martin Buchholz <martin@xemacs.org>
3855 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3856 Ran spell-check on make.texinfo.
3858 2000-06-23 Paul D. Smith <psmith@gnu.org>
3860 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3861 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3862 * make.h: Define these macros.
3864 * Version 3.79.1 released.
3866 * configure.in: Add a new option, --disable-nsec-timestamps, to
3867 avoid using sub-second timestamps on systems that support it. It
3868 can lead to problems, e.g. if your makefile relies on "cp -p".
3869 * README.template: Document the issue with "cp -p".
3871 * config.guess, config.sub: Updated.
