1 2010-07-03 Paul Smith <psmith@gnu.org>
3 * read.c (parse_file_seq): All archive groups must end with ')' as
4 the LAST character in a word. If there is no word ending in ')'
5 then it's not an archive group. Fixes Savannah bug #28525.
7 2010-07-01 Paul Smith <psmith@gnu.org>
9 * main.c (main): Append optional features using separate calls.
10 Not as efficient but not all compilers allow conditionals inside

26 into cmd.exe. Fixes Savannah bug #28126.
28 * file.c (lookup_file) [HAVE_DOS_PATHS]: Treat '\\' like we do

64 which allows the caller to get the index of the matching directory.
66 * make.h (vpath_search): Update prototype.
68 * remake.c (library_search): Implement linker-compatible library
69 search. Use the new VPATH_SEARCH index functionality to keep track
70 of the directory index for each match. Select the match with the
71 lowest directory index.
73 * implicit.c (pattern_search): Pass NULL for the index arguments in
74 the VPATH_SEARCH call.
76 * doc/make.texi (Directory Search for Link Libraries): Describe the
77 new search behavior.
79 * NEWS: Add a note about the new behavior.
81 2009-10-25 Paul Smith <psmith@gnu.org>
83 * AUTHORS, et.al.: Update copyright years.
85 * implicit.c (stemlen_compare): Fix qsort() compare bug that
86 caused implicit rules with equal stem lengths to be sorted
87 indeterminately.
89 2009-10-24 Paul Smith <psmith@gnu.org>
91 * main.c (usage): Add --eval to the usage string.
92 (switches): Add the --eval switch.
93 (main): If --eval is given, add them to the simply-expanded variable
94 -*-eval-flags-*- (necessary to allow recursion to work properly).
95 (define_makeflags): Add -*-eval-flags-*- to MAKEFLAGS.
97 * NEWS: Describe the new --eval command line argument.
98 * doc/make.texi (Options Summary): Document --eval.

126 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
127 to normal upgrade logic from dep_hash_cmp to set_file_variables.
129 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
131 * dep.h (uniquize_deps): Remove.
133 * read.c (uniquize_deps): Merge into set_file_variables in
134 commands.c.
135 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
137 * commands.c (set_file_variables): Avoid modifying the dep
138 chain to achieve uniqueness. Fixes savannah bug 25780.
140 * implicit.c (pattern_search): Instead of re-setting all automatic
141 variables for each rule we try, just update $*.
143 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
145 * variable.h (undefine_variable_in_set): New function declaration.
146 (undefine_variable_global): New macro.

150 * read.c (vmodifiers): Add undefine_v modifier.
151 (parse_var_assignment): Parse undefine.
152 (do_undefine): Handle the undefine directive.
153 (eval): Call do_undefine if undefine_v is set.
155 * main.c (.FEATURES): Add a keyword to indicate the new feature.
157 * doc/make.texi (Undefine Directive): Describe the new directive.
159 * NEWS: Add a note about the new directive.
161 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
163 * implicit.c (pattern_search): Initialize file variables only
164 if we need to parse a rule that requires the second expansion.
166 2009-10-03 Paul Smith <psmith@gnu.org>
168 * make.h: Include <alloca.h> even on systems where __GNUC__ is
169 defined. Not sure why it was done the other way.
170 Requested by David Boyce <dsb@boyski.com>.
172 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
174 * dep.h (dep): Add the DONTCARE bitfield.
176 * filedef.h (file):Add the NO_DIAG bitfield.
178 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
179 not struct file (a file can be a dependency of many targets,
180 some don't care, some do).
182 * remake.c (update_goal_chain): Propagate DONTCARE from struct
183 dep to struct file before updating the goal and restore it
184 afterwards.
185 (update_file): Don't prune the dependency graph if this target
186 has failed but the diagnostics hasn't been issued.
187 (complain): Scan the file's dependency graph to find the file
188 that caused the failure.
189 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
190 whether to print diagnostics.
192 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
194 2009-09-28 Paul Smith <psmith@gnu.org>
196 * doc/make.texi (Pattern Intro): Move the match algorithm
197 discussion into the "Pattern Match" node.

200 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
202 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
203 much of the command line on a single pass.
205 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
207 * varible.c (create_pattern_var): Insert variables into the
208 PATTERN_VARS list in the shortest patterns first order.
210 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
211 used to sort the rules.

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

228 double-colons have a different meaning. Savannah bug #27497.
230 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
232 * configh.dos.template: Remove unconditional definition of
233 SYS_SIGLIST_DECLARED.
234 Include <sys/version.h> because ports of GCC 4.3.0 and later no
235 longer include it, so macros like __DJGPP_MINOR__ are no longer
236 defined automatically.
238 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
239 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
240 instead of using the hardcoded ones.
241 (SUBDIRS): doc subdir added.
242 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
243 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
244 create html formated docs. texi2html may not be ported to DOS.
245 (make.info, make.dvi, make.ps, make.html): Make targets depend on
246 'make.texi'.
247 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
248 -I switch to look in ./ instead of ./doc.
249 (html): Target depend on html-recursive instead of make_1.html.
250 (make_1.html): Removed.
251 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
252 (all-recursive): Allow for more than one subdir in the build
253 process.
254 (mostlyclean-recursive, clean-recursive, distclean-recursive)
255 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
256 (tags-recursive): Allow for more than one subdir in the build
257 process.
258 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
259 targets. Enter into doc/ to produce the targets.
260 (all-am): $(INFO_DEPS) replaced by info.
262 2009-09-26 Paul Smith <psmith@gnu.org>
264 * read.c (record_files): Use free_ns() to free struct nameseq.
265 (eval): Ditto.
267 * rule.c (freerule): Use free_dep_chain().
269 * read.c (record_files): Free FILENAMES chain for implicit rules.
270 (eval): Static pattern targets go into the string cache.
272 * function.c (string_glob): Free NAME in the nameseq chain.
274 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
276 * implicit.c (pattern_search): Terminate early if we haven't
277 found any rules to try (performance improvement).
279 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
281 * implicit.c (pattern_search): Merge three parallel arrays,
282 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
283 of struct TRYRULE. In the old version the latter two arrays
284 had insufficient length.
286 2009-09-24 Paul Smith <psmith@gnu.org>
288 * implicit.c (pattern_search): Add back support for order-only
289 prerequisites for secondary expansion implicit rules, that were
290 accidentally dropped. If we find a "|", enable order-only mode
291 and set IGNORE_MTIME on all deps that are seen afterward.
292 (pattern_search): Fix memory leaks: for intermediate files where
293 we've already set the file variable and pattern variable sets, be
294 sure to either save or free them as appropriate.
296 2009-09-23 Paul Smith <psmith@gnu.org>
298 Rework the way secondary expansion is stored, for efficiency.
299 This changes secondary expansion so that ONLY WHEN we know we have
300 a possibility of needing secondary expansion, do we defer the
301 secondary expansion. This means more parsing the deps but we use
302 a lot less memory (due to the strcache). Also, this fixes
303 Savannah bug #18622.
305 * read.c (eval): Don't parse the dep string here anymore.
306 (record_files): Take the dep argument as an unparsed string. If
307 secondary expansion is enabled AND the prereq string has a '$' in
308 it, then set NEED_2ND_EXPANSION and keep the entire string.
309 Otherwise, parse the dep string here to construct the dep list
310 with the names in the strcache.
312 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
313 duplicate the name string (others are in the strcache).
315 * implicit.c: Remove struct idep and free_idep_chain(): unused.
316 (struct patdeps): New structure to store prereq information.
317 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
318 which prerequisites need expansion, and expand only those.
320 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
321 and enter_prereqs(). split_prereqs() takes a fully-expanded string
322 and splits it into a DEP list, handling order-only prereqs.
323 (enter_prereqs): This function enters a list of DEPs into the file
324 database. If there's a stem defined, expand any pattern chars.
325 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
326 set. Use the above functions.
327 (snap_deps): Only perform second expansion on prereqs that need it,
328 as defined by the NEED_2ND_EXPANSION flag.
329 (print_prereqs): New function to print the prereqs
330 (print_file): Call print_prereqs() rather than print inline.
332 * hash.h (STRING_COMPARE): Take advantage of strcache() by
333 comparing pointers.
334 (STRING_N_COMPARE): Ditto.
335 (ISTRING_COMPARE): Ditto.
337 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
338 (parse_file_seq): Return void*
339 * read.c (parse_file_seq): Return void*.
340 (eval): Invoke macroized version of parse_file_seq()
341 * default.c (set_default_suffixes): Ditto.
342 * file.c (split_prereqs): Ditto.
343 * function.c (string_glob): Ditto.
344 * main.c (main): Ditto.
345 * rule.c (install_pattern_rule): Ditto.
347 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
349 2009-09-16 Paul Smith <psmith@gnu.org>
351 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
352 convert to macros.
353 * dep.h: Create alloc_dep() / free_dep() macros.
355 * implicit.c (pattern_search): Take advantage of the new
356 parse_file_seq() to add the directory prefix to each prereq.
358 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
359 all. Avoid reversing chains. Support adding prefixes.
360 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
361 cached/non-cached results.
362 (eval): Remove multi_glob() & invoke new parse_file_seq().
363 * rule.c (install_pattern_rule): Ditto.
364 * main.c (main): Ditto.
365 * implicit.c (pattern_search): Ditto.
366 * function.c (string_glob): Ditto.
367 * file.c (parse_prereqs): Ditto.
368 * default.c (set_default_suffixes): Ditto.
370 * variable.c (parse_variable_definition): Don't run off the end of
371 the string if it ends in whitespace (found with valgrind).
373 * commands.c (set_file_variables): Keep space for all targets in
374 $? if -B is given (found with valgrind).
376 2009-09-15 Paul Smith <psmith@gnu.org>
378 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
379 (xcalloc): Add new function.
380 * make.h: New declarations.
382 * ar.c (ar_glob_match): New calling method for concat().
383 * main.c (main): Ditto.
384 (decode_env_switches): Ditto.
385 * read.c (eval_makefile): Ditto.
386 (tilde_expand): Ditto.
387 (parse_file_seq): Ditto.
388 * variable.c (target_environment): Ditto.
389 (sync_Path_environment): Ditto.
391 * ar.c (ar_glob_match): Use xcalloc().
392 * dir.c (file_impossible): Ditto.
393 * file.c (enter_file): Ditto.
394 * job.c (new_job): Ditto.
395 * read.c (parse_file_seq): Ditto.
396 * vmsfunctions.c (opendir): Ditto.
398 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
400 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
401 inside the loop that looks up environment for PATH.
403 2009-08-31 Eli Zaretskii <eliz@gnu.org>
405 * function.c (windows32_openpipe): Update envp after calling
406 sync_Path_environment.
408 2009-08-02 Paul Smith <psmith@gnu.org>
410 * remake.c (notice_finished_file): Ensure file->cmds is not null
411 before looping through them. Fixes Savannah bug #21824.
413 * doc/make.texi (Wildcard Examples): Clarify when objects is
414 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
415 (Include): Clarify the behavior of -include.
416 Fixes Savannah bug #18963.
418 2009-08-01 Paul Smith <psmith@gnu.org>
420 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
421 etc. come on the command line. Fixes Savannah bug #27093.
423 * expand.c (expand_argument): If the argument is large enough use
424 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
426 * variable.c (do_variable_definition): Avoid using alloca() to
427 hold values, which can be large. Fixes Savannah bug #23960.
429 * job.c (new_job): Use memmove() instead of strcpy() since both
430 pointers are in the same memory block. Fixes Savannah bug #27148.
431 Patch by Petr Machata.
433 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
435 * job.c (construct_command_argv_internal): Add "ulimit" and
436 "unset" to the sh_cmds for Unixy shells.
438 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
440 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
441 that set make_cv_sys_gnu_glob, so they are also correctly set
442 when the cache has been populated before.
444 2009-07-04 Eli Zaretskii <eliz@gnu.org>
446 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
447 exist, as realpath(3) does where it's supported.
449 2006-07-04 Eli Zaretskii <eliz@gnu.org>
451 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
452 (abspath): Support systems that define HAVE_DOS_PATHS (have
453 drive letters in their file names). Use IS_PATHSEP instead of a
454 literal '/' comparison. Fixes Savannah bug #26886.
456 2009-06-14 Paul Smith <psmith@gnu.org>
458 * remake.c (update_file_1): Remember the original file we marked
459 as updating, so we can clear that flag again. If we find a target
460 via vpath, FILE might change.
461 (check_dep): Ditto. Fixes Savannah bug #13529.
462 Patch by Reid Madsen <reid.madsen@tek.com>.
464 2009-06-13 Paul Smith <psmith@gnu.org>
466 * doc/make.texi (MAKEFILES Variable): Be explicit that files
467 included by MAKEFILES cannot give default goals.
468 * read.c (eval): If set_default is not set, pass the no-default-goal
469 value when we read included makefiles. Fixes Savannah bug #13401.
471 * ar.c (ar_name): Ensure that targets with empty parens aren't
472 considered archive member references: archive members must have a
473 non-empty "member" string. Fixes Savannah bug #18435.
475 * function.c (string_glob): Rely on multi_glob() to determine
476 whether files exist or not. Remove call to file_exists_p() which
477 is not always correct. Fixes Savannah bug #21231.
478 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
479 then only files that really exist will be returned.
480 * dep.h: Add new argument to multi_glob().
481 * rule.c (install_pattern_rule): Ditto.
482 * read.c (eval): Ditto.
483 * main.c (main): Ditto.
484 * implicit.c (pattern_search): Ditto.
485 * file.c (parse_prereqs): Ditto.
486 * default.c (set_default_suffixes): Ditto.
488 2009-06-09 Paul Smith <psmith@gnu.org>
490 * commands.c (set_file_variables): If always_make_flag is set,
491 always add the prereq to $?. Fixes Savannah bug #17825.
493 * remake.c (update_file_1): When rebuilding deps of FILE, also try
494 to rebuild the deps of all the also_make targets for that file.
495 Fixes Savannah bug #19108.
497 * implicit.c (pattern_search): Undo test for is_target, added by
498 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
499 Rule Search Algorithm". Fixes Savannah bug #17752.
501 * main.c (clean_jobserver): Clear the jobserver_fds options and
502 set job_slots to the default when we clean up.
503 (define_makeflags): Return the new MAKEFLAGS value.
504 (main): Reset MAKEFLAGS in the environment when we re-exec.
505 Fixes Savannah bug #18124.
507 2009-06-08 Paul Smith <psmith@gnu.org>
509 * read.c (eval): Collapse continuations post-semicolon on target-
510 specific variables. Fixes Savannah bug #17521.
512 2009-06-07 Paul Smith <psmith@gnu.org>
514 * job.c (reap_children): For older systems without waitpid() (are
515 there any of these left?) run wait(2) inside EINTRLOOP to handle
516 EINTR errors. Fixes Savannah bug #16401.
518 * (various): Debug message cleanup. Fixes Savannah bug #16469.
520 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
522 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
523 not the end, to catch second expansion $(eval ...) defining new
524 target/prereq relationships during snap_deps.
525 Fixes Savannah bug #24622.
527 * read.c (record_files): The second-expansion "f->updating" hack
528 was not completely correct: if assumed that the target with
529 commands always had prerequisites; if one didn't then the ordering
530 was messed up. Fixed for now to use f->updating to decide whether
531 to preserve the last element in the deps list... but this whole
532 area of constructing and reversing the deps list is too confusing
533 and needs to be reworked. Fixes Savannah bug #21198.
535 2009-06-06 Paul Smith <psmith@gnu.org>
537 * hash.c (hash_insert): Remove useless test for NULL.
538 Fixes Savannah bug #21823.
540 * make.h: Move SET_STACK_SIZE determination to make.h.
541 * main.c (main): New global variable, STACK_LIMIT, holds the
542 original stack limit when make was started.
543 * job.c (start_job_command): Reset the stack limit, if we changed it.
544 Fixes Savannah bug #22010.
546 * remake.c (check_dep): Only set the target's state to not-started
547 if it's not already running. Found this while testing -j10 builds
548 of glibc: various targets were being rebuilt multiple times.
549 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
550 bug #15919.
552 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
553 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
554 Bugzilla bug 10246.
556 2009-06-04 Paul Smith <psmith@gnu.org>
558 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
560 * maintMakefile: Modify access of config and gnulib Savannah
561 modules to use GIT instead of CVS.
563 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
564 Fixes Savannah bug #24655.
566 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
567 this can happen during some invocations of $(eval ...) for example.
568 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
570 2009-06-02 Paul Smith <psmith@gnu.org>
572 * configure.in: Check for fileno()
573 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
574 for the makefile file so invocations of $(shell ...) don't inherit it.
575 Fixes Savannah bug #24277.
577 2009-06-01 Paul Smith <psmith@gnu.org>
579 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
580 expansion was handled incorrectly. Rework the default goal
581 handling to save the variable only. Remove default_goal_file and
582 default_goal_name.
583 * read.c (eval): Check default_goal_var, not default_goal_name.
584 * read.c (record_target_var): Don't check default_goal_file here.
586 2009-05-31 Paul Smith <psmith@gnu.org>
588 * main.c (main): Expand the .DEFAULT_GOAL variable before using
589 it, and if the multi_glob() returns nothing (say it expanded to
590 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
592 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
593 $(and ..) to the reference. Fixes Savannah bug #25694.
595 * make.1: Be clear that some recipes will be executed even with -n.
596 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
598 * doc/make.texi (Override Directive): Make more clear how
599 overrides and appends interact.
600 Elucidates part of Savannah bug #26207.
602 * read.c (record_target_var): Don't reset the origin on
603 target-specific variables; try_variable_definition() will handle
604 this correctly. Fixes Savannah bug #26207.
606 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
607 Fixes Savannah bug #25712.
609 * implicit.c (pattern_search): Keep a pointer to the beginning of
610 the filename and save that instead of the constructed pointer.
611 Fixes Savannah bug #26593.
612 Patch by Mark Seaborn <mrs@mythic-beasts.com>
614 2009-05-30 Paul Smith <psmith@gnu.org>
616 * doc/make.texi (Multi-Line): Add a description of the new abilities
617 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
618 "command sequence" vs. "recipe" syntax.
619 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
620 after a define, to create variables with those flavors.
622 2009-05-25 Paul Smith <psmith@gnu.org>
624 Reworked the parser for variable assignments to allow multiple
625 modifiers, and in any order. Also allows variable and
626 prerequisites to be modifier names ('export', 'private', etc.)
628 * NEWS: Add notes about user-visible changes.
630 * read.c (struct vmodifiers): Remember what modifiers were seen.
631 (parse_var_assignment): New function to parse variable assignments.
632 (eval): Call the new function. Handle variable assignments earlier.
634 * variable.c (parse_variable_definition): Only parse; don't create var.
635 (assign_variable_definition): Call parse, then create the var.
637 2009-05-24 Paul Smith <psmith@gnu.org>
639 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
640 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
642 2009-03-14 Eli Zaretskii <eliz@gnu.org>
644 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
645 Fixes Savannah bug #25412.
647 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
648 prototype for xmalloc.
649 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
650 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
651 Loop over an array of extensions, instead of duplicating the same
652 code inline. Use SearchPath followed by CreateFile, instead of
653 the obsolete OpenFile. Fixes Savannah bug #17277.
654 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
655 to `find_file'. Fixes Savannah bug #25662.
657 2009-03-07 Eli Zaretskii <eliz@gnu.org>
659 * function.c (func_shell): Don't close pipedes[1] if it is -1.
660 Fixes Savannah bug #20495.
662 2009-02-28 Ralf Wildenhues <address@hidden>
664 * doc/make.texi (Instead of Execution): Document interaction of
665 -t with phony targets.
667 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
669 Introduce a new keyword "private" which applies to target-specific
670 variables and prevents their values from being inherited.
672 * variable.h (struct variable): Add private_var flag to each variable.
673 Add a flag to specify which list entry switches to the parent target.
674 * variable.c (define_variable_in_set): Initialize private_var flag.
675 (lookup_variable): Skip private variables in parent contexts.

686 if it's available.
687 * make.h: Rename savestring to xstrndup.
688 * commands.c (chop_commands): Ditto.
689 * function.c (func_foreach): Ditto.
690 * read.c (eval, record_files): Ditto.

693 2008-09-30 Eli Zaretskii <eliz@gnu.org>
695 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
696 "-gstabs+ -ggdb3".
698 * w32/subproc/build.bat (GCCBuild): Likewise.
700 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
702 * job.c (construct_command_argv_internal): Avoid extra backslash
703 in batch-mode Unixy shells. Under DB_JOBS, display the contents
704 of the batch file.
706 2008-05-31 Eli Zaretskii <eliz@gnu.org>
708 * README.W32.template: Remove obsolete text about non-support for
709 -jN without Unixy shell. Remove obsolete text about not supplying
710 Visual Studio project files (we do supply them). Modify text to
711 prefer GCC builds to MSC builds.
713 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
715 * doc/make.texi (Empty Targets): Fix typo.

720 * ar.c (ar_glob_match): Zero the allocated structure.
721 * read.c (parse_file_seq): Ditto.
723 2008-03-08 Brian Dessent <brian@dessent.net>
725 * maintMakefile: Update Translation Project location.
727 2008-01-26 Eli Zaretskii <eliz@gnu.org>
729 * variable.c (target_environment): Don't use shell_var if its
730 `value' field is NULL.
732 2007-12-22 Eli Zaretskii <eliz@gnu.org>
734 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
736 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
737 (TEXINFOS): Value changed to `doc/make.texi'.
738 (.SUFFIXES): Use .texi instead of .texinfo.
739 (make.info, make.dvi): Depend on doc/make.texi.
740 (.texi.info): New target, instead of ".texinfo.info". Change -I
741 switch to $(MAKEINFO) to look in doc/. Use --no-split.
742 (.texi): New target, instead of ".texinfo". Change -I switch to
743 $(MAKEINFO) to look in doc/. Use --no-split.
744 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
745 switch to $(MAKEINFO) to look in doc/.
746 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
747 "*.i[0-9][0-9]" (due to --no-split above).
748 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
749 (html, make_1.html): New targets.
750 (.PHONY): Add "html".
751 (.SUFFIXES): Add .html.
753 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
755 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
756 HAVE_DECL_SYS_SIGLIST.
758 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
759 build does not use child_execute_job.
761 * variable.c (define_automatic_variables) [__MSDOS__]: Always
762 export the SHELL environment variable to the child.
764 2007-12-22 Eli Zaretskii <eliz@gnu.org>
766 * config.h.W32: Include sys/types.h.
767 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
769 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
770 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
771 also `:'.
773 2007-11-04 Paul Smith <psmith@gnu.org>
775 * doc/make.texi: Convert references to "commands", "command
776 lines", and "command script" to "recipe".
777 * NEWS: Ditto.
778 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
779 Ditto.
781 2007-10-27 Bruno Haible <bruno@clisp.org>
783 * remake.c (f_mtime): Print time difference values between 100 and
784 ULONG_MAX in fixed-point notation rather than in exponention notation.
786 2007-10-12 Eli Zaretskii <eliz@gnu.org>
788 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
789 a more complex value than a simple shell: if it's not a default
790 shell now then expand it and see if is a default shell then.
792 2007-10-10 Eli Zaretskii <eliz@gnu.org>
794 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
795 pathnames, with const strings.
796 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
797 from the template (used for building from CVS, not a dist).
799 2007-10-10 Paul Smith <psmith@gnu.org>
801 * make.h: Add a prototype for w32_kill() (change suggested by
802 Yongwei Wu <wuyongwei@gmail.com>).
804 2007-09-21 Eli Zaretskii <eliz@gnu.org>
806 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
807 directories in Path.

812 Provided by Diego Biurrun <diego@biurrun.de>
813 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
814 Provided by Diego Biurrun <diego@biurrun.de>
816 2007-09-11 Paul Smith <psmith@gnu.org>
818 * doc/make.texi (Special Variables): Moved this into the "How to
819 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
820 (MAKEFILE_LIST) No longer a section; this was added into the
821 "Special Variables" section.
822 (Rule Introduction): Reference .RECIPEPREFIX.
823 (Simple Makefile): Ditto.
824 (Rule Syntax): Ditto.
825 (Command Syntax): Ditto.
826 (Error Messages): Ditto.
828 2007-09-10 Paul Smith <psmith@gnu.org>
830 * commands.c (print_commands): Don't print an extra line in the
831 command scripts. Prefix the command scripts with cmd_prefix, not \t.
833 * read.c (construct_include_path): Add the full string to the cache; we
834 were chopping the last char.
836 * NEWS: Announce the .RECIPEPREFIX special variable.
837 * variable.c (lookup_special_var): Rename from handle_special_var().
838 (lookup_variable): Call the new name.
839 (set_special_var): New function: handle setting of special variables.
840 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
841 (do_variable_definition): Call it.
842 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
843 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
844 * main.c (main): Create the .RECIPEPREFIX special variable.
845 * read.c (eval): Remove the cmd_prefix characters from the command
846 scripts here, so they're not stored in the commands array at all,
847 rather than waiting and stripping them out during command construction.
848 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
850 2007-08-15 Paul Smith <psmith@gnu.org>
852 * doc/make.texi (GNU Free Documentation License): The fdl.texi
853 file has had the section info removed, so add some to make.texi
854 before we include it.
856 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
858 * remake.c (check_dep): Reset the target state for intermediate
859 files. They might have been considered before but not updated
860 then (order-only for example) but they will be this time.
861 Fixes Savannah bug #'s 3330 and 15919.
863 2007-07-21 Eli Zaretskii <eliz@gnu.org>
865 Fix Savannah bug #20549:
866 * function.c (func_shell): Call construct_command_argv with zero
867 value of FLAGS.
868 * job.c (construct_command_argv_internal): New argument FLAGS; all
869 callers changed.
870 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
871 just_print_flag.
872 * job.h (construct_command_argv_internal): Update prototype.
874 2007-07-13 Paul Smith <psmith@gnu.org>
876 * file.c (expand_deps): Use variable_buffer as the start of the
877 buffer, not the original pointer (in case it was reallocated).
878 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
879 Fixes Savannah bug #20452.
881 2007-07-04 Paul Smith <psmith@gnu.org>
883 * (ALL FILES): Update to GPLv3.
884 * (ALL FILES): Update copyright for 2007.

888 2007-06-29 Thiemo Seufer <ths@mips.com>
890 * maintMakefile: Update Translation Project location.
892 2007-06-13 Paul Smith <psmith@gnu.org>
894 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
895 "Expansion of a deferred"
896 Fixes Savannah bug #20018.

900 Fixes Savannah bug #20033.
902 2007-05-11 Paul Smith <psmith@gnu.org>
904 * job.c (new_job): Add debug info to specify where make found the
905 command script it is running to build a target.
906 Fixes Savannah bug #18617.
908 * default.c (default_suffixes,default_suffix_rules,default_variables):
909 Add support for Objective C. Fixes Savannah bug #16389.
910 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
912 * function.c (func_lastword): Initialize p.
914 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
915 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
916 Dave Korn <dave.korn@artimi.com>
918 2007-05-08 Paul Smith <psmith@gnu.org>
920 Fix Savannah bug #19656:
922 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
924 * make.h: Change all case-insensitive string compares to use
925 strcasecmp() (from POSIX). If we don't have that but do have one
926 of the others, define strcasecmp to be one of those instead. If
927 we don't have any, declare a prototype for our own version.
929 * misc.c (strcasecmp): Use this if we can't find any native
930 case-insensitive string comparison function.
931 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
932 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
933 strcmpi().
934 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
935 strcasecmp() instead of stricmp().
936 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
937 instead of strcmpi().
938 * acinclude.m4: Remove the strcasecmp() check from here.
940 2007-03-21 Paul Smith <psmith@gnu.org>
942 * configure.in: Don't turn on case-insensitive file system support
943 if --disable-... is given. Fixes Savannah bug #19348.
945 2007-03-19 Paul Smith <psmith@gnu.org>
947 * ALL: Use the strcache for all file name strings, or other
948 strings which we will never free. The goal is to save memory by
949 avoiding duplicate copies of strings. However, at the moment this
950 doesn't save much memory in most situations: due to secondary
951 expansion we actually save prerequisite lists twice (once before
952 the secondary expansion, and then again after it's been parsed
953 into individual file names in the dep list). We will resolve this
954 in a future change, by doing the parsing up-front for targets
955 where secondary expansion is not set.
957 Moving things into the strcache also allows us to use const
958 pointers in many more places.
960 2007-01-03 Paul Smith <psmith@gnu.org>
962 * make.h (ENULLLOOP): Reset errno after each failed invocation of
963 the function, not just the first. Fixes Savannah bug #18680.
965 2006-11-18 Paul Smith <psmith@gnu.org>
967 * strcache.c (strcache_add_len): Don't allocate a new buffer
968 unless the string is not already nil-terminated. Technically this
969 is a violation of the standard, since we may be passed an array
970 that is not long enough to test one past. However, in make this
971 is never true since we only use nil-terminated strings or
972 sub-strings thereof.
974 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
976 * main.c: New global cmd_prefix, defaults to '\t'.
977 * job.c (construct_command_argv_internal): Use cmd_prefix instead
978 of '\t'.
980 * dir.c: Constified.
981 (dir_contents_file_exists_p): Check for an error return from
982 readdir(), just in case.
984 * commands.c: Constified.
985 * default.c: Constified.
986 * expand.c: Constified.
987 * function.c: Partial constification.
988 * variable.c: Partial constification.
989 * vmsify.c: Constification. Hard to test this but I hope I didn't
990 screw it up!
991 * vpath.c: Partial constification.
992 * w32/pathstuff.c: Partial constification.
994 2006-11-16 Eli Zaretskii <eliz@gnu.org>
996 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
997 backslashes and drive letters as absolute.
999 2006-10-22 Paul Smith <psmith@gnu.org>
1001 * main.c (struct command_switch): Use const and void*.
1003 2006-10-21 Paul Smith <psmith@gnu.org>
1005 * ar.c: Constified.
1006 * arscan.c: Constified.
1008 2006-09-30 Paul Smith <psmith@gnu.org>
1010 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1011 point to lastword since the example was updated.
1012 Fixes Savannah bug #16304.
1013 (Secondary Expansion): Correct example description.
1014 Fixes Savannah bug #16468.
1015 (Makefile Contents): Clarify that comments cannot appear within
1016 variable references or function calls.
1017 Fixes Savannah bug #16577.
1018 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1019 Fixes Savannah bug #17701.
1020 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1021 (Prerequisite Types): Added an example of using order-only
1022 prerequisites. Fixes Savannah bug #17880.
1023 (Rule Syntax): "lise" -> "list"
1024 (Multiple Rules): ... -> @dots{}
1025 (Splitting Lines): ditto.
1027 * remake.c (update_file_1): Prereqs that don't exist should be
1028 considered changed, for the purposes of $?.
1029 Fixes Savannah bug #16051.
1031 * make.1: Remove extraneous "+".
1032 Fixes Savannah bug #16652.
1034 2006-09-06 Paul D. Smith <psmith@gnu.org>
1036 * configure.in: Include sys/types.h when checking for sys/wait.h.
1038 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1040 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1041 $PATH_SEPARATOR.
1043 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1044 Normally, it is defined in config.h.
1046 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1047 well.
1049 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1050 sh_chars_sh for Windows platforms that emulate Unix.
1052 2006-05-07 Paul D. Smith <psmith@gnu.org>
1054 * README.OS2.template: Updates provided by Andreas Buening
1055 <andreas.buening@nexgo.de>.
1057 2006-04-30 Paul D. Smith <psmith@gnu.org>
1059 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1060 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1062 2006-04-26 Paul D. Smith <psmith@gnu.org>
1064 * README.cvs: Add a reminder to notify the GNU translation robot.
1066 * doc/make.texi: Change @direcategory (requested by Karl Berry).
1068 2006-04-20 Paul D. Smith <psmith@gnu.org>
1070 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1071 that don't have extended grep.
1072 (cvsclean): Use $(PERL) instead of perl.
1074 2006-04-09 Paul D. Smith <psmith@gnu.org>
1076 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1078 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1079 inner-scope variables don't mask outer-scope variables.
1081 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1082 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1083 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1084 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1085 values from memory allocation functions: they return void* and so
1086 don't need to be cast. Also remove (char *) casts of arguments to
1087 xrealloc().
1089 * configure.in: Remove checks for memcpy/memmove/strchr.
1091 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1093 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp
1094 calls to memset/memcpy/memmove/memcmp calls.
1095 * expand.c, file.c, function.c, getloadavg.c, implicit.c: Ditto.
1096 * job.c, main.c, misc.c, read.c, remake.c, rule.c: Ditto.
1097 * variable.c, vpath.c: Ditto.

1101 2006-04-06 Paul D. Smith <psmith@gnu.org>
1103 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1104 require an ISO C 1989 standard compiler and runtime library.
1106 * Makefile.am: Remove the ansi2knr feature.
1108 * make.h: Remove the PARAMS() macro definition and all uses of it.
1110 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
1111 * commands.c, commands.h, config.h-vms.template: Ditto.
1112 * dep.h, dir.c, expand.c, filedef.h, function.c: Ditto.
1113 * implicit.c, job.c, job.h, main.c, read.c, remake.c: Ditto.
1114 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
1116 * NEWS: Update.
1118 2006-04-01 Paul D. Smith <psmith@gnu.org>
1120 Version 3.81 released.
1122 * NEWS: Updated for 3.81.
1124 * README.cvs: Mention that vpath builds are not supported out of
1125 CVS. Fixes Savannah bug #16236.
1126 Remove update of make.texi from the list of things to do; we use
1127 version.texi now.
1129 2006-03-26 Paul D. Smith <psmith@gnu.org>
1131 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1132 support from automake, as described in the Texinfo manual.
1134 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1136 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1137 with lastslash, since the latter points to filename, not to
1138 target.
1139 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1140 Declare and define sh_chars_sh[].
1142 2006-03-23 Paul D. Smith <psmith@gnu.org>
1144 * configure.in: Look for build.sh.in in $srcdir so it will be
1145 built for remote configurations as well.
1147 * Makefile.am: Make sure to clean up build.sh during distclean.
1148 Fixes Savannah bug #16166.
1150 * misc.c (log_access): Takes a const char *.
1151 * function.c (fold_newlines): Takes an unsigned int *.
1152 Both fixes for Savannah bug #16170.
1154 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1156 * implicit.c (pattern_search): Call set_file_variables only
1157 if we have prerequisites that need second expansion. Fixes
1158 Savannah bug #16140.
1160 2006-03-19 Paul D. Smith <psmith@gnu.org>
1162 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1163 memory on hosts that don't support it directly.
1165 * README.cvs: Add information on steps for making a release (to
1166 make sure I don't forget any).
1168 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1169 function.
1170 (die): Cleanup code was removed from here; call the new function.
1171 (main): If we are re-execing, clean up the jobserver first so we
1172 don't leak file descriptors.
1173 Reported by Craig Fithian <craig.fithian@citigroup.com>
1175 2006-03-17 Paul D. Smith <psmith@gnu.org>
1177 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1178 allow multiple concurrent runs.
1179 Patch from Joseph Myers <joseph@codesourcery.com>
1181 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1183 * dep.h (struct dep): Add the stem field.
1184 * misc.c (alloc_dep, free_dep): New functions.
1185 (copy_dep_chain): Copy stem.
1186 (free_dep_chain): Use free_dep.
1187 * read.c (record_files): Store stem in the dependency line.
1188 * file.c (expand_deps): Use stem stored in the dependency line. Use
1189 free_dep_chain instead of free_ns_chain.
1190 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1191 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1192 * main.c (main, handle_non_switch_argument): Ditto.
1193 * remake.c (check_dep): Ditto.
1194 * rule.c (convert_suffix_rule, freerule): Ditto.
1196 2006-03-14 Paul D. Smith <psmith@gnu.org>
1198 * expand.c (variable_append): Instead of appending everything then
1199 expanding the result, we expand (or not, if it's simple) each part
1200 as we add it.
1201 (allocated_variable_append): Don't expand the final result.
1202 Fixes Savannah bug #15913.
1204 2006-03-09 Paul Smith <psmith@gnu.org>
1206 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1207 listed non-existent files as changed. Turns out there's a bug in
1208 the Linux kernel builds which means that this change causes
1209 everything to rebuild every time. We will re-introduce this fix
1210 in the next release, to give them time to fix their build system.
1211 Fixes Savannah bug #16002.
1212 Introduces Savannah bug #16051.
1214 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1215 we *don't* find UNIX "/".
1216 Reported by David Ergo <david.ergo@alterface.com>
1218 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1220 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1221 locator function find_and_set_default_shell if SHELL came from the
1222 command line.
1224 2006-02-20 Paul D. Smith <psmith@gnu.org>
1226 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1227 to be null; don't core in that case.
1229 2006-02-19 Paul D. Smith <psmith@gnu.org>
1231 * commands.c (set_file_variables): Realloc, not malloc, the static
1232 string values to avoid memory leaks.
1234 * expand.c (recursively_expand_for_file): Only set reading_file to
1235 an initialized value.
1237 * implicit.c (pattern_search): We need to make a copy of the stem
1238 if we get it from an intermediate dep, since those get freed.
1240 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1241 begin with ".".
1242 (enter_file) [VMS]: Ditto.
1243 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1245 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1247 * job.c (construct_command_argv_internal): Fix last change.
1249 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1250 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1251 the calls to _beginthreadex.
1253 * expand.c (recursively_expand_for_file): Initialize `save' to
1254 prevent compiler warnings.
1256 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1258 * job.c (construct_command_argv_internal): Don't create a temporary
1259 script/batch file if we are under -n. Call _setmode to switch the
1260 script file stream to text mode.
1262 2006-02-17 Paul D. Smith <psmith@gnu.org>
1264 * variable.c (merge_variable_set_lists): Don't try to merge the
1265 global_setlist. Not only is this useless, but it can lead to
1266 circularities in the linked list, if global_setlist->next in one
1267 list gets set to point to another list which also ends in
1268 global_setlist.
1269 Fixes Savannah bug #15757.
1271 2006-02-15 Paul D. Smith <psmith@gnu.org>
1273 Fix for Savannah bug #106.
1275 * expand.c (expanding_var): Keep track of which variable we're
1276 expanding. If no variable is being expanded, it's the same as
1277 reading_file.
1278 * make.h (expanding_var): Declare it.
1279 * expand.c (recursively_expand_for_file): Set expanding_var to the
1280 current variable we're expanding, unless there's no file info in
1281 it (could happen if it comes from the command line or a default
1282 variable). Restore it before we exit.
1283 * expand.c (variable_expand_string): Use the expanding_var file
1284 info instead of the reading_file info.
1285 * function.c (check_numeric): Ditto.
1286 (func_word): Ditto.
1287 (func_wordlist): Ditto.
1288 (func_error): Ditto.
1289 (expand_builtin_function): Ditto.
1290 (handle_function): Ditto.
1292 2006-02-14 Paul D. Smith <psmith@gnu.org>
1294 * read.c (eval): Even if the included filenames expands to the
1295 empty string we still need to free the allocated buffer.
1297 * implicit.c (pattern_search): If we allocated a variable set for
1298 an impossible file, free it.
1299 * variable.c (free_variable_set): New function.
1300 * variable.h: Declare it.
1302 * read.c (read_all_makefiles): Makefile names are kept in the
1303 strcache, so there's never any need to alloc/free them.
1304 (eval): Ditto.
1306 * main.c (main): Add "archives" to the .FEATURES variable if
1307 archive support is enabled.
1308 * doc/make.texi (Special Variables): Document it.
1310 2006-02-13 Paul D. Smith <psmith@gnu.org>
1312 * implicit.c (pattern_search): Add checking for DOS pathnames to
1313 the pattern rule target LASTSLASH manipulation.
1314 Fixes Savannah bug #11183.
1316 2006-02-11 Paul D. Smith <psmith@gnu.org>
1318 * (ALL FILES): Updated copyright and license notices.
1320 2006-02-10 Paul D. Smith <psmith@gnu.org>
1322 A new internal capability: the string cache is a read-only cache
1323 of strings, with a hash table interface for fast lookup. Nothing
1324 in the cache will ever be freed, so there's no need for reference
1325 counting, etc. This is the beginning of a full solution for
1326 Savannah bug #15182, but for now we only store makefile names here.
1328 * strcache.c: New file. Implement a read-only string cache.
1329 * make.h: Add prototypes for new functions.
1330 * main.c (initialize_global_hash_tables): Initialize the string cache.
1331 (print_data_base): Print string cache stats.
1332 * read.c (eval_makefile): Use the string cache to store makefile
1333 names. Rewrite the string allocation to be sure we free everything.
1335 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1337 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1338 directory time stamp didn't change, except on FAT filesystems.
1339 Suggested by J. David Bryan <jdbryan@acm.org>.
1341 2006-02-09 Paul D. Smith <psmith@gnu.org>
1343 * function.c (func_or): Implement a short-circuiting OR function.
1344 (func_and): Implement a short-circuiting AND function.
1345 (function_table_init): Update the table with the new functions.
1346 * doc/make.texi (Conditional Functions): Changed the "if" section
1347 to one on general conditional functions. Added documentation for
1348 $(and ...) and $(or ...) functions.
1349 * NEWS: Note new $(and ...) and $(or ...) functions.
1351 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1353 * job.h (struct child): Add the dontcare bitfield.
1354 * job.c (new_job): Cache dontcare flag.
1355 * job.c (reap_children): Use cached dontcare flag instead of the
1356 one in struct file. Fixes Savannah bug #15641.
1358 2006-02-06 Paul D. Smith <psmith@gnu.org>
1360 * vpath.c (selective_vpath_search): If the file we find has a
1361 timestamp from -o or -W, use that instead of the real time.
1362 * remake.c (f_mtime): If the mtime is a special token from -o or
1363 -W, don't overwrite it with the real mtime.
1364 Fixes Savannah bug #15341.
1366 Updates from Markus Mauhart <qwe123@chello.at>:
1368 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1369 (process_signal, process_last_err, process_exit_code): Manage
1370 invalid handle values.
1371 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1372 manage invalid handles; remove them.
1373 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1374 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1375 * README.cvs: Updates for building from CVS.
1377 2006-02-05 Paul D. Smith <psmith@gnu.org>
1379 * file.c (enter_file): Keep track of the last double_colon entry,
1380 to avoid walking the list every time we want to add a new one.
1381 Fixes Savannah bug #15533.
1382 * filedef.h (struct file): Add a new LAST pointer.
1384 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1385 the comparison. For 64-bits systems the result of the subtraction
1386 might not fit into an int. Use comparison instead.
1387 Fixes Savannah bug #15534.
1389 * doc/make.texi: Update the chapter on writing commands to reflect
1390 the changes made in 3.81 for backslash/newline and SHELL handling.
1392 2006-02-01 Paul D. Smith <psmith@gnu.org>
1394 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1395 variable st is not used when it's not initialized.
1396 Patch from Eli Zaretskii <eliz@gnu.org>.
1398 2006-01-31 Paul D. Smith <psmith@gnu.org>

1404 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1405 J. Grant <jg@jguk.org>.
1407 * main.c: Update the copyright year in the version output.
1408 * prepare_w32.bat: Remove this file from the distribution.
1410 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1412 * remake.c (update_goal_chain): Set g->changed instead of
1413 incrementing it, as it is only 8-bit wide, and could overflow if
1414 many commands got started in update_file.
1416 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1418 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1419 MAXIMUM_WAIT_OBJECTS.
1420 (process_wait_for_any_private): Change dimension of handles[]
1421 array to MAXIMUM_WAIT_OBJECTS.
1422 (process_used_slots): New function.
1423 (process_register): Don't register more processes than the
1424 available number of slots.
1425 (process_easy): Don't start new processes if all slots are used up.
1427 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1428 are already more children than sub_proc.c can handle, behave as if
1429 the load were too high.
1430 (start_job_command): Fix a typo in error message when process_easy
1431 fails.
1433 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1435 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1436 the shell is not sh.exe.
1438 * job.c (create_batch_file): Renamed from create_batch_filename;
1439 all callers changed. Don't close the temporary file; return its
1440 file descriptor instead. New arg FD allows to return the file
1441 descriptor.
1442 (construct_command_argv_internal): Use _fdopen instead of fopen to
1443 open the batch file.
1445 2006-01-04 Paul D. Smith <psmith@gnu.org>
1447 * readme.vms: Updates for case-insensitive VMS file systems from
1448 Hartmut Becker <Hartmut.Becker@hp.com>.

1460 doesn't exist.
1462 * read.c (eval): Be sure to strip off trailing whitespace from the

1464 struct dep when creating a new one.
1466 2005-12-28 Paul D. Smith <psmith@gnu.org>
1468 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1469 disable warnings for MSC.
1470 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1472 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1474 * doc/make.texi (Execution): Add a footnote about changes in
1475 handling of backslash-newline sequences. Mention the differences
1476 on MS-DOS and MS-Windows.
1478 * NEWS: More details about building the MinGW port and a pointer
1479 to README.W32. Fix the section name that describes the new
1480 backward-incompatible processing of backslash-newline sequences.
1481 The special processing of SHELL set to "cmd" is only relevant to
1482 MS-Windows, not MS-DOS.
1484 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1486 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1487 to DWORD, to avoid compiler warnings.
1488 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1489 use %ld in format, to avoid compiler warnings.
1491 * doc/make.texi (Special Targets): Fix a typo.
1492 (Appending): Fix cross-reference to Setting.
1493 (Special Variables, Secondary Expansion, File Name Functions)
1494 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1495 periods after a sentence.
1496 (Execution): Add @: after "e.g.".
1497 (Environment): Fix punctuation.
1498 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1499 (Shell Function, Target-specific): Add @: after "vs."
1501 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1503 * read.c (record_target_var): Initialize variable's export field
1504 with v_default instead of leaving it "initialized" by whatever
1505 garbage happened to be on the heap.
1507 2005-12-12 Paul D. Smith <psmith@gnu.org>
1509 * make.1: Fix some display errors and document all existing options.
1510 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1512 2005-12-11 Paul D. Smith <psmith@gnu.org>
1514 * implicit.c (pattern_search): If 2nd expansion is not set for
1515 this implicit rule, replace the pattern with the stem directly,
1516 and don't re-expand the variable list. Along with the other
1517 .SECONDEXPANSION changes below, fixes bug #13781.
1519 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1521 * implicit.c (pattern_search): Mark other files that this rule
1522 builds as targets so that they are not treated as intermediates
1523 by the pattern rule search algorithm. Fixes bug #13022.
1525 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1527 * remake.c (notice_finished_file): Propagate the change of
1528 modification time to all the double-colon entries only if
1529 it is the last one to be updated. Fixes bug #14334.
1531 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1533 * function.c (func_flavor): Implement the flavor function which
1534 returns the flavor of a variable.
1535 * doc/make.texi (Functions for Transforming Text): Document it.
1536 * NEWS: Add it to the list of new functions.
1538 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1540 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1541 variable.
1542 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1543 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1545 2005-10-26 Paul Smith <psmith@gnu.org>
1547 * read.c (record_files): Don't set deps flags if there are no deps.
1548 * maintMakefile: We only need to build the templates when we are
1549 creating a distribution, so don't do it for "all".
1551 2005-10-24 Paul D. Smith <psmith@gnu.org>
1553 Make secondary expansion optional: its enabled by declaring the
1554 special target .SECONDEXPANSION.

1560 prerequisite list was found in a static pattern rule.
1561 (free_dep_chain): Declare a prototype.
1562 * file.c (parse_prereqs): New function: break out some complexity
1563 from expand_deps().
1564 (expand_deps): If we aren't doing second expansion, replace % with
1565 the stem for static pattern rules. Call the new function.
1566 * filedef.h (parse_prereqs): Declare a prototype.
1567 * implicit.c (pattern_search): Initialize the new staticpattern
1568 field.
1569 * main.c (second_expansion): Declare a global variable to remember
1570 if the special target has been seen. Initialize the new
1571 staticpattern field for prerequisites.
1572 * make.h: Extern for second_expansion.
1573 * misc.c (free_dep_chain): New function: frees a struct dep list.
1574 * read.c (read_all_makefiles): Initialize the staticpattern field.
1575 (eval_makefile): Ditto.
1576 (record_files): Check for the .SECONDEXPANSION target and set
1577 second_expansion global if it's found.
1578 Use the new free_dep_chain() instead of doing it by hand.
1579 Set the staticpattern field for prereqs of static pattern targets.
1581 2005-10-16 Paul D. Smith <psmith@gnu.org>
1583 * main.c (main): Set CURDIR to be a file variable instead of a
1584 default, so that values of CURDIR inherited from the environment
1585 won't override the make value.
1587 2005-09-26 Paul D. Smith <psmith@gnu.org>
1589 * job.c (construct_command_argv_internal): If the line is empty
1590 remember to free the temporary argv strings.
1591 Fixes bug # 14527.
1593 2005-09-16 Paul D. Smith <psmith@gnu.org>
1595 * job.c (start_job_command): The noerror flag is a boolean (single
1596 bit); set it appropriately.
1597 Reported by Mark Eichin <eichin@metacarta.com>
1599 2005-08-29 Paul D. Smith <psmith@gnu.org>
1601 * function.c (func_error): On Windows, output from $(info ...)
1602 seems to come in the wrong order. Try to force it with fflush().
1604 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1606 * read.c (record_files): Move code that sets stem for static
1607 pattern rules out of the if (!two_colon) condition so it is
1608 also executed for two-colon rules. Fixes Savannah bug #13881.
1610 2005-08-08 Paul D. Smith <psmith@gnu.org>
1612 * make.h: Don't test that __STDC__ is non-0. Some compilers
1613 (Windows for example) set it to 0 to denote "ISO C + extensions".
1614 Fixes bug # 13594.
1616 2005-08-07 Paul D. Smith <psmith@gnu.org>
1618 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1619 conditional (slightly different version of a fix from Eli).
1621 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1622 If make is running in parallel without -k and two jobs die in a
1623 row, but not too close to each other, then make will quit without
1624 waiting for the rest of the jobs to die.
1626 * main.c (die): Don't reset err before calling reap_children() the
1627 second time: we still want it to be in the error condition.
1628 * job.c (reap_children): Use a static variable, rather than err,
1629 to control whether or not the error message should be printed.
1631 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1633 * w32/subproc/sub_proc.c: Include signal.h.
1634 (process_pipe_io, process_file_io): Pass a pointer to a local
1635 DWORD variable to GetExitCodeProcess. If the exit code is
1636 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1638 * job.c [WINDOWS32]: Include windows.h.
1639 (main_thread) [WINDOWS32]: New global variable.
1640 (reap_children) [WINDOWS32]: Get the handle for the main thread
1641 and store it in main_thread.
1643 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1644 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1645 doing anything else. When we are done, close the main thread
1646 handle and exit with status 130.
1648 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1650 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1651 pointer to fprintf.
1653 * main.c (find_and_set_default_shell): If found a DOSish shell,
1654 set sh_found and the value of default_shell, and report the
1655 findings in debug mode.
1657 * job.c (construct_command_argv_internal): Check unixy_shell, not
1658 no_default_sh_exe, to decide whether to use Unixy or DOSish
1659 builtin commands.
1661 * README.W32: Update with info about the MinGW build.
1663 * build_w32.bat: Support MinGW.
1665 * w32/subproc/build.bat: Likewise.
1667 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1668 printing DWORD args.
1670 * function.c (windows32_openpipe): Fix format strings for printing
1671 DWORD args.
1673 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1674 'reap_mode'.
1675 (start_job_command): Fix format string for printing the result of
1676 process_easy.
1677 (start_job_command) [WINDOWS32]: Do not define.
1678 (exec_command): Fix format string for printing HANDLE args.
1680 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1681 to avoid compiler warnings.
1682 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1683 (Note: some of these fixes were submitted independently by J. Grant)
1685 2005-07-30 J. Grant <jg@jguk.org>
1687 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1688 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1689 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1691 2005-07-15 Paul Smith <psmith@gnu.org>
1693 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1694 we don't have a POSIX shell, then revert to the old
1695 backslash-newline behavior (where they are stripped).
1696 Fixes bug #13665.
1698 2005-07-08 Paul D. Smith <psmith@gnu.org>
1700 * config.h.W32.template: Reorder to match the standard config.h,
1701 for easier comparisons.
1702 From J. Grant <jg@jguk.org>
1704 * maintMakefile: Remove .dep_segment before overwriting it, in
1705 case it's not writable or noclobber is set.
1706 * expand.c (variable_expand_string): Cast result of pointer
1707 arithmetic to avoid a warning.
1708 * main.c (switches): Add full-fledged final initializer.
1710 2005-07-06 Paul D. Smith <psmith@gnu.org>
1712 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1713 * signame.c (strsignal): If we found _sys_siglist[] or
1714 __sys_siglist[] use those instead of sys_siglist[].
1715 From Albert Chin <china@thewrittenword.com>
1717 2005-07-04 Paul D. Smith <psmith@gnu.org>
1719 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1720 globfree(); set up to use the GNU versions.
1721 From Martin Zinser <zinser@zinser.no-ip.info>
1723 2005-07-03 Paul D. Smith <psmith@gnu.org>
1725 From J. Grant <jg@jguk.org>:
1727 * README.W32.template: Update the Windows and tested MSVC versions.
1728 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1729 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1730 * build_w32.bat: Ditto.
1731 * w32/subproc/build.bat: Ditto.
1733 2005-06-28 Paul D. Smith <psmith@gnu.org>
1735 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1736 declaration was checked but not present.
1738 2005-06-27 Paul D. Smith <psmith@gnu.org>
1740 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1741 to unsigned long. Fixes Savannah bug #13550.
1743 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1744 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1745 Fixes Savannah bug #13551.
1747 2005-06-26 Paul D. Smith <psmith@gnu.org>
1749 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1750 it if ANSI_STRING is not set.
1752 2005-06-25 Paul D. Smith <psmith@gnu.org>
1754 * read.c (eval): If no filenames are passed to any of the
1755 "include" variants, don't print an error.
1756 * doc/make.texi (Include): Document this.
1757 Fixes Savannah bug #1761.
1759 * job.c (construct_command_argv_internal): Sanitize handling of
1760 backslash/newline pairs according to POSIX: that is, keep the
1761 backslash-newline in the command script, but remove a following
1762 TAB character, if present. In the fast path, make sure that the
1763 behavior matches what the shell would do both inside and outside
1764 of quotes. In the slow path, quote the backslash and put a
1765 literal newline in the string.
1766 Fixes Savannah bug #1332.
1767 * doc/make.texi (Execution): Document the new behavior and give
1768 some examples.
1769 * NEWS: Make a note of the new behavior.
1771 * make.h [WINDOWS32]: #include <direct.h>.
1772 Fixes Savannah bug #13478.
1774 * remake.c (name_mtime): If the stat() of a file fails and the -L
1775 option was given and the file is a symlink, take the best mtime of
1776 the symlink we can get as the mtime of the file and don't fail.
1777 Fixes Savannah bug #13280.
1779 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1780 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1781 inside a variable reference. Make this function static as it's
1782 only used here.
1783 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1784 parsing an unexpanded line looking for semicolons.
1785 Fixes Savannah bug #1454.
1786 * misc.c (remove_comments): Move this to read.c and make it static
1787 as it's only used there. Call find_char_unquote() with new arg.
1788 * make.h: Remove prototypes for find_char_unquote() and
1789 remove_comments() since they're static now.
1791 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1792 its export flag and obtain its value. When we need to re-exec,
1793 increment the value and add it into the environment.
1794 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1795 * NEWS: Mention MAKE_RESTARTS.
1796 * main.c (always_make_set): New variable. Change the -B option to
1797 set this one instead.
1798 (main): When checking makefiles, only set always_make_flag if
1799 always_make_set is set AND the restarts flag is 0. When building
1800 normal targets, set it IFF always_make_set is set.
1801 (main): Avoid infinite recursion with -W, too: only set what-if
1802 files to NEW before we check makefiles if we've never restarted
1803 before. If we have restarted, set what-if files to NEW _after_ we
1804 check makefiles.
1805 Fixes Savannah bug #7566:
1807 2005-06-17 Paul D. Smith <psmith@gnu.org>
1809 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1810 in the prerequisites list.
1812 2005-06-12 Paul D. Smith <psmith@gnu.org>
1814 Fix Savannah bug # 1328.
1816 * configure.in: Check for atexit().
1817 * misc.c (close_stdout): Test stdout to see if writes to it have
1818 failed. If so, be sure to exit with a non-0 error code. Based on
1819 code found in gnulib.
1820 * make.h: Prototype.
1821 * main.c (main): Install close_stdout() with atexit().
1823 2005-06-10 Paul D. Smith <psmith@gnu.org>
1825 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1827 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1828 headers; make vmsWaitForChildren() static; extern vmsify().
1829 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1830 Don't create child_execute_job() here (it's in vmsjobs.c).
1831 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1833 2005-06-09 Paul D. Smith <psmith@gnu.org>
1835 * variable.c (push_new_variable_scope): File variables point
1836 directly to the global_setlist variable. So, inserting a new
1837 scope in front of that has no effect on those variables: they
1838 don't go through current_variable_set_list. If we're pushing a
1839 scope and the current scope is global, push it "the other way" so
1840 that the new setlist is in the global_setlist variable, and
1841 next points to a new setlist with the global variable set.
1842 (pop_variable_scope): Properly undo a push with the new
1843 semantics.
1844 Fixes Savannah bug #11913.
1846 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1848 * job.c (reap_children): Don't die of the command failed but
1849 the dontcare flag is set. Fixes Savannah bug #13216.
1851 * implicit.c (pattern_search): When creating a target from
1852 an implicit rule match, lookup pattern target and set precious
1853 flag in a newly created target. Fixes Savannah bug #13218.
1855 2005-05-13 Paul D. Smith <psmith@gnu.org>
1857 Implement "if... else if... endif" syntax.
1859 * read.c (eval): Push all checks for conditional words ("ifeq",
1860 "else", etc.) down into the conditional_line() function.
1861 (conditional_line): Rework to allow "else if..." clause. New
1862 return value -2 for lines which are not conditionals. The
1863 ignoring flag can now also be 2, which means "already parsed a
1864 true branch". If that value is seen no other branch of this
1865 conditional can be considered true. In the else parsing if there
1866 is extra text after the else, invoke conditional_line()
1867 recursively to see if it's another conditional. If not, it's an
1868 error. If so, raise the conditional value to this level instead
1869 of creating a new conditional nesting level. Special check for
1870 "else" and "endif", which aren't allowed on the "else" line.
1871 * doc/make.texi (Conditional Syntax): Document the new syntax.
1873 2005-05-09 Paul D. Smith <psmith@gnu.org>
1875 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1876 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1877 recurses to the w32 directory, even on non-Windows systems. Use
1878 the method suggested in the automake manual.
1879 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1880 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1882 2005-05-07 Paul D. Smith <psmith@gnu.org>
1884 * main.c (die): If we're dying with a fatal error (not that a
1885 command has failed), write back any leftover tokens before we go.
1887 * job.c (set_child_handler_action_flags): If there are jobs
1888 waiting for the load to go down, set an alarm to go off in 1
1889 second. This allows us to wake up from a potentially long-lasting
1890 read() and start a new job if the load has gone down. Turn it off
1891 after the read.
1892 (job_noop): Dummy signal handler function.
1893 (new_job): Invoke it with the new semantics.
1895 * docs/make.texi: Document secondary expansion. Various cleanups
1896 and random work.
1898 2005-05-03 Paul D. Smith <psmith@gnu.org>
1900 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1901 the targets which are to ultimately be made are called "goals";
1902 see the GNU make manual. Also, MAKECMDGOALS, etc.
1904 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1905 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1906 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1908 2005-05-02 Paul D. Smith <psmith@gnu.org>
1910 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1911 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1912 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1913 functions to vmsjobs.c. #include it into jobs.c.
1915 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1916 jobserver tokens. I found that this happens when an exported
1917 recursive variable contains a $(shell ...) function reference: in
1918 this situation we could "forget" to write back a token.
1920 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1921 we have. It's not reliable to depend on the number of children in
1922 our linked list so keep a separate count.
1923 (new_job): Check jobserver_tokens rather than children &&
1924 waiting_jobs. Increment jobserver_tokens when we get one.
1925 (free_child): If jobserver_tokens is 0, internal error. If it's
1926 >1, write a token back to the jobserver pipe (we don't write a
1927 token for the "free" job). Decrement jobserver_tokens.
1929 * main.c: Add variable master_job_slots.
1930 (main): Set it to hold the number of jobs requested if we're the
1931 master process, when using the jobserver.
1932 (die): Sanity checks: first test jobserver_tokens to make sure
1933 this process isn't holding any tokens we didn't write back.
1934 Second, if master_job_slots is set count the tokens left in the
1935 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1937 2005-04-24 Paul D. Smith <psmith@gnu.org>
1939 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1940 with -l# can lose jobserver tokens, because waiting jobs are not
1941 consulted properly when checking for the "free" token.
1943 * job.c (free_child): Count waiting_jobs as having tokens.
1944 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1945 handle jobs waiting for the load to drop.
1947 2005-04-23 Paul D. Smith <psmith@gnu.org>
1949 * main.c (main): Be careful to not core if a variable setting in
1950 the environment doesn't contain an '='. This is illegal but can
1951 happen in broken setups.
1952 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1954 2005-04-12 Paul D. Smith <psmith@gnu.org>
1956 The second expansion feature causes significant slowdown. Timing
1957 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1958 read the makefile before the feature, to 11+s to do the same
1959 operations after the feature. Additionally, memory usage
1960 increased drastically. To fix this I added some intelligence that
1961 avoids the overhead of the second expansion unless it's required.
1963 * dep.h: Add a new boolean field, need_2nd_expansion.
1965 * read.c (eval): When creating the struct dep for the target,
1966 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1967 (record_files): If there's a "%" in a static pattern rule, it gets
1968 converted to "$*" so set need_2nd_expansion to 1.
1970 * file.c (expand_deps): Rework to be more efficient. Only perform
1971 initialize_file_variables(), set_file_variables(), and
1972 variable_expand_for_file() if the need_2nd_expansion is set.
1974 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1975 (pattern_search): Ditto.
1976 * main.c (handle_non_switch_argument): Ditto.
1977 (main): Ditto.
1978 * read.c (read_all_makefiles): Ditto.
1979 (eval_makefile): Ditto.
1981 2005-04-07 Paul D. Smith <psmith@gnu.org>
1983 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1984 * variable.c (sync_Path_environment): Ditto.
1985 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1987 * main.c (main): Define the .FEATURES variable.
1988 * NEWS: Announce .FEATURES.
1989 * doc/make.texi (Special Variables): Document .FEATURES.
1991 * remake.c (check_dep): If a file is .PHONY, update it even if
1992 it's marked intermediate. Fixes Savannah bug #12331.
1994 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1996 * file.c (expand_deps): Factor out the second expansion and
1997 prerequisite line parsing logic from snap_deps().
1999 * file.c (snap_deps): Use expand_deps(). Expand and parse
2000 prerequisites of the .SUFFIXES special target first. Fixes
2001 Savannah bug #12320.
2003 2005-03-13 Paul D. Smith <psmith@gnu.org>
2005 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2006 Zaretskii.
2008 2005-03-11 Paul D. Smith <psmith@gnu.org>
2010 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2011 available, not undefined (from Earnie Boyd).
2013 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2015 * implicit.c (pattern_search): Mark an intermediate target as
2016 precious if it happened to be a prerequisite of some (other)
2017 target. Fixes Savannah bug #12267.
2019 2005-03-09 Paul D. Smith <psmith@gnu.org>
2021 * read.c (eval_makefile): Add alloca(0).
2022 (eval_buffer): Ditto.
2024 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2026 * main.c (main): Use o_file instead of o_default when defining
2027 the .DEFAULT_TARGET special variable.
2028 * read.c (eval): Use define_variable_global() instead of
2029 define_variable() when setting new value for the .DEFAULT_TARGET
2030 special variable. Fixes Savannah bug #12266.
2032 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2034 * imlicit.c (pattern_search): Mark files for which an implicit
2035 rule has been found as targets. Fixes Savannah bug #12202.
2037 2005-03-04 Paul D. Smith <psmith@gnu.org>
2039 * AUTHORS: Update.
2040 * doc/make.texi (Automatic Variables): Document $|.
2042 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2044 * read.c (record_files): Instead of substituting % with
2045 actual stem value in dependency list replace it with $*.
2046 This fixes stem triple expansion bug.
2048 * implicit.c (pattern_search): Copy stem to a separate
2049 buffer and make it a properly terminated string. Assign
2050 this buffer instead of STEM (which is not terminated) to
2051 f->stem. Instead of substituting % with actual stem value
2052 in dependency list replace it with $*. This fixes stem
2053 triple expansion bug.
2055 2005-03-01 Paul D. Smith <psmith@gnu.org>
2057 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2058 on Windows, as it takes a handle not a pid. Just exit.
2059 Fix from patch #3679, provided by Alessandro Vesely.
2061 * configure.in: Update check for sys_siglist[] from autoconf manual.
2062 * signame.c (strsignal): Update to use the new autoconf macro.
2064 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2066 * read.c (record_files): Add a check for the list of prerequisites
2067 of a static pattern rule being empty. Fixes Savannah bug #12180.
2069 2005-02-28 Paul D. Smith <psmith@gnu.org>
2071 * doc/make.texi (Text Functions): Update docs to allow the end
2072 ordinal for $(wordlist ...) to be 0.
2073 * function.c (func_wordlist): Fail if the start ordinal for
2074 $(wordlist ...) is <1. Matches documentation.
2075 Resolves Savannah support request #103195.
2077 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2078 previously we were stopping when !-q, exactly the opposite. This
2079 has been wrong since version 1.34, in 1994!
2080 (update_file): If we got an error don't break out to run more
2081 double-colon rules: just return immediately.
2082 Fixes Savannah bug #7144.
2084 2005-02-27 Paul D. Smith <psmith@gnu.org>
2086 * misc.c (end_of_token): Make argument const.
2087 * make.h: Update prototype.
2089 * function.c (abspath, func_realpath, func_abspath): Use
2090 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2091 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2092 * read.c (record_files): Ditto.
2093 * variable.c (do_variable_definition): Ditto.
2095 * function.c (func_error): Create a new function $(info ...) that
2096 simply prints the message to stdout with no extras.
2097 (function_table_init): Add new function to the table.
2098 * NEWS: Add $(info ...) reference.
2099 * doc/make.texi (Make Control Functions): Document it.
2101 New feature: if the system supports symbolic links, and the user
2102 provides the -L/--check-symlink-time flag, then use the latest
2103 mtime between the symlink(s) and the target file.
2105 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2106 readlink(). If both are available, define MAKE_SYMLINKS.
2107 * main.c: New variable: check_symlink_flag.
2108 (usage): Add a line for -L/--check-symlink-times to the help string.
2109 (switches): Add -L/--check-symlink-times command line argument.
2110 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2111 print a warning and disable it again.
2112 * make.h: Declare check_symlink_flag.
2113 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2114 if the file is a symlink then check each link in the chain and
2115 choose the NEWEST mtime we find as the mtime for the file. The
2116 newest mtime might be the file itself!
2117 * NEWS: Add information about this new feature.
2118 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2120 Avoid core dumps described in Savannah bug # 12124:
2122 * file.c: New variable snapped_deps remember whether we've run
2123 snap_deps().
2124 (snap_deps): Set it.
2125 * filedef.h: Extern it.
2126 * read.c (record_files): Check snapped_deps; if it's set then
2127 we're trying to eval a new target/prerequisite relationship from
2128 within a command script, which we don't support. Fatal.
2130 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2132 Implementation of the .DEFAULT_TARGET special variable.
2134 * read.c (eval): If necessary, update default_target_name when
2135 reading rules.
2136 * read.c (record_files): Update default_target_file if
2137 default_target_name has changed.
2138 * main.c (default_target_name): Define.
2139 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2140 default_target_name is set use default_target_file as a root
2141 target to make.
2142 * filedef.h (default_target_name): Declare.
2143 * dep.h (free_dep_chain):
2144 * misc.c (free_dep_chain): Change to operate on struct nameseq
2145 and change name to free_ns_chain.
2146 * file.c (snap_deps): Update to use free_ns_chain.
2148 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2150 Implementation of the second expansion in explicit rules,
2151 static pattern rules and implicit rules.
2153 * read.c (eval): Refrain from chopping up rule's dependencies.
2154 Store them in a struct dep as a single dependency line. Remove
2155 the code that implements SySV-style automatic variables.
2157 * read.c (record_files): Adjust the code that handles static
2158 pattern rules to expand all percents instead of only the first
2159 one. Reverse the order in which dependencies are stored so that
2160 when the second expansion reverses them again they appear in
2161 the makefile order (with some exceptions, see comments in
2162 the code). Remove the code that implements SySV-style automatic
2163 variables.
2165 * file.c (snap_deps): Implement the second expansion and chopping
2166 of dependency lines for explicit rules.
2168 * implicit.c (struct idep): Define an auxiliary data type to hold
2169 implicit rule's dependencies after stem substitution and
2170 expansion.
2172 * implicit.c (free_idep_chain): Implement.
2174 * implicit.c (get_next_word): Implement helper function for
2175 parsing implicit rule's dependency lines into words taking
2176 into account variable expansion requests. Used in the stem
2177 splitting code.
2179 * implicit.c (pattern_search): Implement the second expansion
2180 for implicit rules. Also fixes bug #12091.
2182 * commands.h (set_file_variables): Declare.
2183 * commands.c (set_file_variables): Remove static specifier.
2185 * dep.h (free_dep_chain): Declare.
2186 * misc.c (free_dep_chain): Implement.
2188 * variable.h (variable_expand_for_file): Declare.
2189 * expand.c (variable_expand_for_file): Remove static specifier.
2191 * make.h (strip_whitespace): Declare.
2192 * function.c (strip_whitespace): Remove static specifier.
2194 2005-02-26 Paul D. Smith <psmith@gnu.org>
2196 * main.c (main): Check for ferror() when reading makefiles from stdin.
2197 Apparently some shells in Windows don't close pipes properly and
2198 require this check.
2200 2005-02-24 Jonathan Grant <jg@jguk.org>
2202 * configure.in: Add MinGW configuration options, and extra w32 code
2203 directory.
2204 * Makefile.am: Add MinGW configuration options, and extra w32 code
2205 directory.
2206 * main.c: Determine correct program string (after last \ without .exe).
2207 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2208 type fix x2
2209 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2210 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2211 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2212 environment support.
2214 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2216 * function.c (func_shell): When initializing error_prefix, check
2217 that reading file name is not null. This fixes long-standing
2218 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2220 2005-02-09 Paul D. Smith <psmith@gnu.org>
2222 * maintMakefile: Update the CVS download URL to simplify them.
2223 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2224 downloading the .texi files from Savannah now.
2226 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2228 * main.c (handle_non_switch_argument): Only add variables to
2229 command_variables if they're not already there: duplicate settings
2230 waste space and can be confusing to read.
2232 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2233 this header is never included by non-WINDOWS32 code, and it
2234 requires <config.h> to define which isn't always included first.
2236 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2237 testing MINGW32 versions.
2239 * main.c (log_working_directory): flush stdout to be sure the WD
2240 change is printed before any stderr messages show up.
2242 2005-02-01 Paul D. Smith <psmith@gnu.org>
2244 * maintMakefile (po_repo): Update the GNU translation site URL.
2246 2004-12-01 Paul D. Smith <psmith@gnu.org>
2248 * main.c (main): Change char* env_shell to struct variable shell_var.
2249 * variable.c (target_environment): Use new shell_var.
2251 2004-11-30 Paul D. Smith <psmith@gnu.org>
2253 * configure.in: The old way we avoided creating build.sh from
2254 build.sh.in before build.sh.in exists doesn't work anymore; we
2255 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2256 the help!). This also keeps automake from complaining.
2257 * Makefile.am (README): Add a dummy target so automake won't
2258 complain that this file doesn't exist when we checkout from CVS.
2259 * maintMakefile (.dep_segment): Rewrite this rule since newer
2260 versions of automake don't provide DEP_FILES.
2262 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2264 Implementation of `realpath' and `abspath' built-in functions.
2266 * configure.in: Check for realpath.
2267 * function.c (abspath): Return an absolute file name that does
2268 not contain any `.' or `..' components, nor repeated `/'.
2269 * function.c (func_abspath): For each name call abspath.
2270 * function.c (func_realpath): For each name call realpath
2271 from libc or delegate to abspath if realpath is not available.
2272 * doc/make.texi (Functions for File Names): Document new functions.
2273 * doc/make.texi (Quick Reference): Ditto.
2275 2004-11-28 Paul D. Smith <psmith@gnu.org>
2277 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2278 arguments. Fixes bug #10252.
2280 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2282 * main.c (main): Set SHELL to v_noexport by default. Remember the
2283 original environment setting of SHELL in the env_shell variable.
2284 * main.h: Export new env_shell variable.
2285 * variable.c (target_environment): If we find a v_noexport
2286 variable for SHELL, add a SHELL variable with the env_shell value.
2287 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2288 * doc/make.texi (Variables/Recursion): Ditto.
2290 2004-11-28 Paul D. Smith <psmith@gnu.org>
2292 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2293 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2294 Patch by Alessandro Vesely.
2296 2004-11-12 Paul D. Smith <psmith@gnu.org>
2298 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2299 the command line if it's inside a string.
2300 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2302 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2304 * function.c (func_lastword): New function: return last word
2305 from the list of words.
2306 * doc/make.texi: Document $(lastword ). Fix broken links in
2307 Quick Reference section.
2309 2004-10-06 Paul D. Smith <psmith@gnu.org>
2311 Apply patch from Alessandro Vesely, provided with bug # 9748.
2312 Fix use of tmpnam() to work with Borland C.
2314 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2315 construction of a temporary filename, and call new function
2316 create_batch_filename().
2317 (create_batch_filename) [WINDOWS32]: New function to create a
2318 temporary filename.
2320 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2322 * read.c (record_target_var): Expand simple pattern-specific
2323 variable.
2324 * variable.c (initialize_file_variables): Do not expand simple
2325 pattern-specific variable.
2327 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2329 * remake.c (update_file_1): When rebuilding makefiles inherit
2330 dontcare flag from a target that triggered update.
2332 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2334 * variable.c (initialize_file_variables): Mark pattern-specific
2335 variable as a per-target and copy export status.
2337 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2339 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2341 * implicit.c (pattern_search): When considering an implicit rule's
2342 prerequisite check that it is actually a target rather then
2343 just an entry in the file hashtable.
2345 2004-09-21 Paul D. Smith <psmith@gnu.org>
2347 * read.c (readstring): Fix some logic errors in backslash handling.
2348 (eval): Remove some unnecessary processing in buffer handling.
2349 (record_target_var): Assert that parse_variable_definition() succeeded.
2350 Reported by: Markus Mauhart <qwe123@chello.at>.
2352 * misc.c: Removed the sindex() function. All instances of this
2353 function were trivially replaceable by the standard strstr()
2354 function, and that function will always have better (or certainly
2355 no worse) performance than the very simple-minded algorithm
2356 sindex() used. This can matter with complex makefiles.
2357 * make.h: Remove the prototype for sindex().
2358 * function.c (subst_expand): Convert sindex() call to strstr().
2359 This means we no longer need to track the TLEN value so remove that.
2360 (func_findstring): Convert sindex() to strstr().
2361 * commands.c (chop_commands): Convert sindex() calls to strstr().
2362 Suggested by: Markus Mauhart <qwe123@chello.at>.
2364 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2365 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2366 If SHELL is set to CMD.EXE then assume it's batch-mode and
2367 non-unixy. I wrote the code differently from the patch, though,
2368 to make it safer. This also resolves bug #9174.
2370 2004-09-20 Paul D. Smith <psmith@gnu.org>
2372 * expand.c (variable_expand_string): Modify to invoke
2373 patsubst_expand() instead of subst_expand(); the latter didn't
2374 handle suffix patterns correctly.
2375 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2376 was used only from variable_expand_string() and is no longer used
2377 there.
2378 (func_subst): Ditto, on call to subst_expand().
2379 (patsubst_expand): Require the percent pointers to point to the
2380 character after the %, not to the % itself.
2381 * read.c (record_files): New call criteria for patsubst_expand().
2382 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2383 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2385 2004-09-19 Paul D. Smith <psmith@gnu.org>
2387 * function.c (subst_expand): Fix a check in by_word: look for a
2388 previous blank if we're beyond the beginning of the string, not
2389 the beginning of the word.
2390 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2392 2004-05-16 Paul D. Smith <psmith@gnu.org>
2394 * remake.c (update_goal_chain): Change the argument specifying
2395 whether we're rebuilding makefiles to be a global variable,
2396 REBUILDING_MAKEFILES.
2397 (complain): Extract the code that complains about no rules to make
2398 a target into a separate function.
2399 (update_file_1): If we tried to rebuild a file during the makefile
2400 rebuild phase and it was dontcare, then no message was printed.
2401 If we then try to build the same file during the normal build,
2402 print a message this time.
2403 (remake_file): Don't complain about un-remake-able files when
2404 we're rebuilding makefiles.
2406 2004-05-11 Paul D. Smith <psmith@gnu.org>
2408 * job.c (construct_command_argv_internal): OS/2 patches from
2409 Andreas Buening <andreas.buening@nexgo.de>.
2411 2004-05-10 Paul D. Smith <psmith@gnu.org>
2413 * remake.c (update_file): Don't walk the double-colon chain unless
2414 this is a double-colon rule. Fix suggested by Boris Kolpackov
2415 <boris@kolpackov.net>.
2417 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2418 * readme.vms: New section describing OpenVMS support and issues.
2419 * default.c (default_variables): Add support for IA64.
2420 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2421 without some privilege aborts make with the error
2422 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2423 pressing Ctrl+Y and the input device is no terminal. The change
2424 catches this error and just continues.
2426 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2428 2004-04-25 Paul D. Smith <psmith@gnu.org>
2430 * commands.c (set_file_variables): Set $< properly in the face of
2431 order-only prerequisites.
2432 Patch from Boris Kolpackov <boris@kolpackov.net>
2434 2004-04-21 Bob Byrnes <byrnes@curl.com>
2436 * main.c (main): Notice failures to remake makefiles.
2438 2004-03-28 Paul D. Smith <psmith@gnu.org>
2440 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2442 * job.c: No default shell for RISC OS.
2443 (load_too_high): Hard-code the return to 1.
2444 (construct_command_argv_internal): No sh_chars or sh_cmds.
2445 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2447 2004-03-20 Paul D. Smith <psmith@gnu.org>
2449 * variable.c (do_variable_definition): Don't append from the
2450 global set if a previous non-appending target-specific variable
2451 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2452 (with fix).
2454 * expand.c (reference_variable): Don't give up on variables with
2455 no value that have the target-specific append flag set: they might
2456 have a value after all. Reported by Oliver Schmidt
2457 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2458 <nikulin@dx1cmd.inp.nsk.su>.
2460 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2461 refer to absolute pathnames in directories that don't exist: some
2462 portion of the makefile could create those directories before we
2463 match the pattern. Fixes bugs #775 and #108.
2465 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2467 * main.c (main): Free makefile_mtimes if we have any.
2468 * README.W32.template: Update documentation for the current status
2469 of the MS-Windows port.
2470 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2471 environment variable is sometimes already defined which causes the
2472 build to fail.
2473 * main.c (debug_signal_handler): Only define this function if
2474 SIGUSR1 is available.
2476 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2478 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2479 * README.OS2.template: Documentation updates.
2480 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2481 link line for safety.
2482 * maintMakefile (build.sh.in): Remove an extraneous ")".
2483 * job.c (child_execute_job): Close saved FDs.
2484 * job.c (exec_command) [OS/2]: exec_command(): If the command
2485 can't be exec'ed and if the shell is not Unix-sh, then try again
2486 with argv = { "cmd", "/c", ... }. Normally, this code is never
2487 reached for the cmd shell unless the command really doesn't exist.
2488 (construct_command_argv_internal) [OS/2]: The code for cmd
2489 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2490 The CMD builtin commands are case insensitive so use strcasecmp().
2492 2004-03-19 Paul D. Smith <psmith@gnu.org>
2494 * read.c (do_define): Re-order line counter increment so the count
2495 is accurate (we were losing one line per define). Reported by
2496 Dave Yost <Dave@Yost.com>.
2498 2004-03-06 Paul D. Smith <psmith@gnu.org>
2500 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2501 compiler.
2502 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2503 * misc.c (message,error,fatal): Ditto.
2504 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2505 * config.h.W32.template: Ditto.
2506 * config.h-vms.template: Ditto.
2507 * config.ami.template: Ditto.
2509 2004-03-04 Paul D. Smith <psmith@gnu.org>
2511 * README.template: Add a note about broken /bin/sh on SunOS
2512 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2514 * misc.c (message, error, fatal): Don't use "..." if we're using
2515 varargs. ansi2knr should handle this but it doesn't work: it
2516 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2517 done. On many systems (SunOS for example) va_dcl is a #define.
2518 So, force the use of the non-"..." version on pre-ANSI compilers.
2520 * maintMakefile (sign-dist): Create some rules to help automate
2521 the new GNU ftp upload method.
2523 2004-02-24 Paul D. Smith <psmith@gnu.org>
2525 * config.h.W32.template: Add HAVE_STDARG_H
2526 * config.h-vms.template: Ditto.
2527 * config.ami.template: Ditto.
2529 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2531 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2532 * build_w32.bat: Remove extra "+".
2534 2004-02-23 Paul D. Smith <psmith@gnu.org>
2536 * make.h: Create an UNUSED macro to mark unused parameters.
2537 * (many): Clean up warnings by applying UNUSED, fixing
2538 signed/unsigned incompatibilities, etc.
2540 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2541 autoconf warnings.
2542 * filedef.h: Name the command_state enumeration.
2543 * file.c (set_command_state): Use the enumeration in the function
2544 argument.
2546 * configure.in: Explicitly set SET_MAKE to empty, to disable
2547 MAKE=make even when no make already exists. Fix bug #3823.
2549 2004-02-22 Paul D. Smith <psmith@gnu.org>
2551 * maintMakefile: Perl script to clean up all non-CVS files. Use
2552 it on all the subdirectories for the cvs-clean target.
2554 * main.c (decode_switches): Require non-empty strings for all our
2555 string command-line options. Fixes Debian bug # 164165.
2557 * configure.in: Check for stdarg.h and varargs.h.
2558 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2559 for printing messages.
2560 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2561 (message): Ditto.
2562 (error): Ditto.
2563 (fatal): Ditto.
2565 A number of patches for OS/2 support from Andreas Buening
2566 <andreas.buening@nexgo.de>:
2568 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2569 disable the SIGCHLD handler.
2570 (reap_children) [OS/2]: Remove special handling of job_rfd.
2571 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2572 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2573 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2574 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2575 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2576 systems.
2578 2004-02-21 Paul D. Smith <psmith@gnu.org>
2580 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2581 <mail@kristov.de> reports that if process_begin() fails we don't
2582 handle the error condition correctly in all cases.
2583 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2584 to have a newline on the message.
2586 * job.c (construct_command_argv_internal): Add "test" to UNIX
2587 sh_cmds[]. Fixes Savannah bug # 7606.
2589 2004-02-04 Paul D. Smith <psmith@gnu.org>
2591 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2592 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2593 Hartmut Becker <Hartmut.Becker@hp.com>.
2595 2004-01-21 Paul D. Smith <psmith@gnu.org>
2597 * job.c (load_too_high): Implement an algorithm to control the
2598 "thundering herd" problem when using -l to control job creation
2599 via the load average. The system only recomputes the load once a
2600 second but we can start many jobs in a second. To solve this we
2601 keep track of the number of jobs started in the last second and
2602 apply a weight to try to guess what a correct load would be.
2603 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2604 Also fixes bug #4693.
2605 (reap_children): Decrease the job count for this second.
2606 (start_job_command): Increase the job count for this second.
2608 * read.c (conditional_line): Expand the text after ifn?def before
2609 checking to see if it's a single word. Fixes bug #7257.
2611 2004-01-09 Paul D. Smith <psmith@gnu.org>
2613 * file.c (print_file): Recurse to print all targets in
2614 double-colon rules. Fixes bug #4518, reported (with patch) by
2615 Andrew Chatham <chatham@google.com>.
2617 2004-01-07 Paul D. Smith <psmith@gnu.org>
2619 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2620 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2621 AC_FUNC_SETVBUF_REVERSED.
2623 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2624 (MAKE Variable): Fix Savannah bug #4898.
2626 * job.c (construct_command_argv_internal): Add "!" to the list of
2627 shell escape chars. POSIX sh allows it to appear before a
2628 command, to negate the exit code. Fixes bug #6404.
2630 * implicit.c (pattern_search): When matching an implicit rule,
2631 remember which dependencies have the ignore_mtime flag set.
2632 Original fix provided in Savannah patch #2349, by Benoit
2633 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2635 2003-11-22 Paul D. Smith <psmith@gnu.org>
2637 * README.W32.template (Outputs): Clarification on -j with
2638 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2639 <jg-make@jguk.org>.
2641 2003-11-02 Paul D. Smith <psmith@gnu.org>
2643 * function.c (func_if): Strip all the trailing whitespace from the
2644 condition, then don't expand it. Fixed bug # 5798.
2646 * expand.c (recursively_expand_for_file): If we're expanding a
2647 variable with no file context, then use the variable's context.
2648 Fixes bug # 6195.
2650 2003-10-21 Paul D. Smith <psmith@gnu.org>
2652 * main.c (log_working_directory): Add newlines to printf()s.
2654 * README.cvs: Add a note to ignore warnings during autoreconf.
2656 * maintMakefile (po_repo): Set a new URL for PO file updates.
2657 (get-config/config.guess get-config/config.sub): Get these files
2658 from the Savannah config project instead of ftp.gnu.org.
2660 2003-10-05 Paul Eggert <eggert@twinsun.com>
2662 * main.c (main): Avoid potential subscript error if environ has
2663 short strings.
2665 2003-08-22 Paul D. Smith <psmith@gnu.org>
2667 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2668 systems which don't yet implement the C89 standard :-/.
2670 2003-07-18 Paul D. Smith <psmith@gnu.org>
2672 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2673 [WINDOWS32]: Initialize hash.
2675 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2677 * dir.c (read_dirstream): Provide a workaround for broken versions of
2678 the MinGW dirent structure.
2680 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2682 * w32/include/dirent.h: Add __MINGW32__ filter.
2684 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2686 * make.h: Add global declaration of *make_host.
2687 * main.c (print_usage): Remove local declaration of *make_host.
2688 (print_version): Display "This program built for ..." after Copyright
2689 notice.
2691 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2693 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2694 execution of "makeinfo --html make.texi".
2696 2003-04-30 Paul D. Smith <psmith@gnu.org>
2698 * build.template: Make some changes to maybe allow this script to
2699 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2701 * README.OS2.template: New file for OS/2 support. Original
2702 contributed by Andreas Buening.
2703 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2704 DOS-style paths.
2706 2003-04-19 Paul D. Smith <psmith@gnu.org>
2708 Fix bug #1405: allow a target to match multiple pattern-specific
2709 variables.
2711 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2712 variable.c, where they've always belonged.
2713 * rule.h: Move the prototypes and struct pattern_var as well.
2714 * variable.c (initialize_file_variables): Invoke
2715 lookup_pattern_var() in a loop, until no more matches are found.
2716 If a match is found, create a new variable set for the target's
2717 pattern variables. Then merge the contents of each matching
2718 pattern variable set into the target's pattern variable set.
2719 (lookup_pattern_var): Change this function to be usable
2720 in a loop. It takes a starting position: if NULL, start at the
2721 beginning; if non-NULL, start with the pattern variable after that
2722 position, and return the next matching pattern.
2723 (create_pattern_var): Create a unique instance of
2724 pattern-specific variables for every definition in the makefile.
2725 Don't combine the same pattern together. This allows us to
2726 process the variable handling properly even when the same pattern
2727 is used multiple times.
2728 (parse_variable_definition): New function: break out the parsing
2729 of a variable definition line from try_variable_definition.
2730 (try_variable_definition): Call parse_variable_definition to
2731 parse.
2732 (print_variable_data_base): Print out pattern-specific variables.
2733 * variable.h (struct variable): Remember when a variable is
2734 conditional. Also remember its flavor.
2735 (struct pattern_var): Instead of keeping a variable set, we just
2736 keep a single variable for each pattern.
2737 * read.c (record_target_var): Each pattern variable contains only a
2738 single variable, not a set, so create it properly.
2739 * doc/make.texi (Pattern-specific): Document the new behavior.
2741 2003-04-17 Paul D. Smith <psmith@gnu.org>
2743 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2744 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2745 file/directory naming rules for VMS so I can't tell whether this
2746 is correct or not.
2748 2003-04-09 Paul D. Smith <psmith@gnu.org>
2750 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2751 DOS-style pathnames: backslash separators and drive specifiers.
2753 2003-03-28 Paul D. Smith <psmith@gnu.org>
2755 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2756 the intermediate flag on all targets. Fixes bug #2515.
2758 2003-03-24 Paul D. Smith <psmith@gnu.org>
2760 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2761 Upgrade to autoconf 2.57 and automake 1.7.3.
2763 * job.c: More OS/2 changes from Andreas Buening.
2765 * file.c (print_file): Fix variable initialization.
2766 Fixes bug #2892.
2768 * remake.c (notice_finished_file):
2770 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2771 some calls (like readdir()) return NULL in valid situations
2772 without resetting errno. Fixes bug #2846.
2774 2003-02-25 Paul D. Smith <psmith@gnu.org>
2776 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2778 * job.c (_is_unixy_shell) [OS/2]: New function.
2779 Set default shell to /bin/sh.
2780 (reap_children): Close the job_rfd pipe here since we don't use a
2781 SIGCHLD handler.
2782 (set_child_handler_action_flags): define this to empty on OS/2.
2783 (start_job_command): Close the jobserver pipe and use
2784 child_execute_job() instead of fork/exec.
2785 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2786 rather than exec'ing, then reconfigure stdin/stdout.
2787 (exec_command): Rewrite to use spawn instead of exec. Return the
2788 PID of the child.
2790 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2791 in DOS. Handle the TEMP environment variable as in DOS. Don't
2792 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2793 use -j in DOS mode. Use child_execute_job() instead of
2794 exec_command().
2796 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2797 spawn() instead.
2799 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2800 prototypes that return values.
2802 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2804 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2805 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2806 for OS/2.
2807 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2808 DOS paths.
2810 2003-02-24 Paul D. Smith <psmith@gnu.org>
2812 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2813 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2814 (child_execute_job) [VMS]: Handle error status properly.
2815 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2817 * function.c (func_shell): Use EINTRLOOP() while reading from the
2818 subshell pipe (Fixes bug #2502).
2819 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2820 jobserver pipe.
2821 * main.c (main): Ditto.
2823 2003-01-30 Paul D. Smith <psmith@gnu.org>
2825 * read.c (eval): eval() was not fully reentrant, because the
2826 collapsed buffer was static. Change it to be an automatic
2827 variable so that eval() can be invoked recursively.
2828 Fixes bug # 2238.
2829 (eval): Apply patch # 1022: fix memory reference error on long
2830 target-specific variable lines.
2831 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2833 * function.c (check_numeric): Combine the is_numeric() function
2834 into this function, since it's only called from one place.
2835 Constify this function. Have it print the incorrect string in the
2836 error message. Fixes bug #2407.
2837 (strip_whitespace): Constify.
2838 (func_if): Constify.
2839 * expand.c (expand_argument): Constify.
2841 2003-01-29 Paul D. Smith <psmith@gnu.org>
2843 Fix bug # 2169, also reported by other people on various systems.
2845 * make.h: Some systems, such as Solaris and PTX, do not fully
2846 implement POSIX-compliant SA_RESTART functionality; important
2847 system calls like stat() and readdir() can still fail with EINTR
2848 even if SA_RESTART has been set on the signal handler. So,
2849 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2850 EINTR for system calls which return -1 or 0 (NULL), respectively,
2851 on error.
2852 Also, remove the old atomic_stat()/atomic_readdir() and
2853 HAVE_BROKEN_RESTART handling.
2855 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2857 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2858 * remake.c (touch_file): Ditto.
2860 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2861 * read.c (construct_include_path): Ditto.
2862 * remake.c (name_mtime): Ditto.
2863 * vpath.c (selective_vpath_search): Ditto.
2864 * dir.c (find_directory): Ditto.
2865 (local_stat): Ditto.
2866 (find_directory): Use ENULLLOOP() to wrap opendir().
2867 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2869 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2870 atomic_readdir() handling.
2872 2003-01-22 Paul D. Smith <psmith@gnu.org>
2874 * function.c (func_call): Fix Bug #1744. If we're inside a
2875 recursive invocation of $(call ...), mask any of the outer
2876 invocation's arguments that aren't used by this one, so that this
2877 invocation doesn't "inherit" them accidentally.
2879 2002-12-05 Paul D. Smith <psmith@gnu.org>
2881 * function.c (subst_expand): Valery Khamenia reported a
2882 pathological performance hit when doing substitutions on very
2883 large values with lots of words: turns out we were invoking
2884 strlen() a ridiculous number of times. Instead of having each
2885 call to sindex() call strlen() again, keep track of how much of
2886 the text we've seen and pass the length to sindex().
2888 2002-11-19 Paul D. Smith <psmith@gnu.org>
2890 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2893 2002-11-16 Paul D. Smith <psmith@gnu.org>
2895 * NMakefile.template (OBJS): Add hash.c object file.
2896 * SMakefile.template (srcs): Ditto.
2897 * Makefile.ami (objs): Ditto.
2898 * build_w32.bat: Ditto.
2900 * Makefile.DOS.template: Remove extra dependencies.
2902 2002-10-25 Paul D. Smith <psmith@gnu.org>
2904 * expand.c (install_variable_buffer): New function. Install a new
2905 variable_buffer context and return the previous one.
2906 (restore_variable_buffer): New function. Free the current
2907 variable_buffer context and put a previously saved one back.
2908 * variable.h: Prototypes for {install,restore}_variable_buffer.
2909 * function.c (func_eval): Push a new variable_buffer context
2910 before we eval, then restore the old one when we're done.
2911 Fixes Bug #1517.
2913 * read.c (install_conditionals): New function. Install a new
2914 conditional context and return the previous one.
2915 (restore_conditionals): New function. Free the current
2916 conditional context and put a previously saved one back.
2917 (eval): Use the {install,restore}_conditionals for "include"
2918 handling.
2919 (eval_buffer): Use {install,restore}_conditionals to preserve the
2920 present conditional state before we evaluate the buffer.
2921 Fixes Bug #1516.
2923 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2924 and $(value ...).
2925 (Recursion): Add a variable index entry for CURDIR.
2927 * README.cvs: Update to appropriate versions.
2928 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2929 don't need to copy loadavg.c: automake is smart enough to create
2930 it for me. Still have a bug in automake related to ansi2knr tho.
2932 2002-10-14 Paul D. Smith <psmith@gnu.org>
2934 * remake.c (notice_finished_file): Only touch targets if they have
2935 at least one command (as per POSIX). Resolve Bug #1418.
2937 * *.c: Convert to using ANSI C-style function definitions.
2938 * Makefile.am: Enable the ansi2knr feature of automake.
2939 * configure.in: ditto.
2941 2002-10-13 Paul D. Smith <psmith@gnu.org>
2943 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2944 for automatic variable values like $^, etc. In the case of very
2945 large lists of prerequisites this causes problems. Instead reuse
2946 a static buffer (resizeable) for each variable.
2948 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2949 target-specific variable definitions. Check for it and set an
2950 "exported" flag.
2951 (record_target_var): Set the export field to v_export if the
2952 "exported" flag is set.
2953 * doc/make.texi (Target-specific): Document the ability to use
2954 "export".
2956 * doc/make.texi: Change the name of the section on automatic
2957 variables from "Automatic" to "Automatic Variables". Added text
2958 clarifying the scope of automatic variables.
2960 2002-10-04 Paul D. Smith <psmith@gnu.org>
2962 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2963 as () braces.
2964 (record_files): Ditto.
2966 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2967 the search for the '=' to only within the enclosing parens.
2969 2002-10-03 Paul D. Smith <psmith@gnu.org>
2971 Version 3.80 released.
2973 * dir.c: Change hash functions to use K&R function definition style.
2974 * function.c: Ditto.
2975 * read.c: Ditto.
2976 * variable.c: Ditto.
2978 Update to automake 1.7.
2980 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2981 (pdf): Remove this target as automake now provides one.
2983 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2985 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2987 * makefile.com: Updates for GNU make 3.80.
2988 * makefile.vms: Ditto.
2990 2002-09-23 Paul D. Smith <psmith@gnu.org>
2992 * read.c (enum make_word_type): Remove w_comment.
2993 (get_next_mword): Don't treat comment characters as special; where
2994 this function is used we will never see a comment (it's stripped
2995 before we get here) and treating comments specially means that
2996 targets like "foo\#bar" aren't handled properly.
2998 2002-09-18 Paul D. Smith <psmith@gnu.org>
3000 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3002 * read.c (eval): Expansion of arguments to export/unexport was
3003 ignoring all arguments after the first one. Change the algorithm
3004 to expand the whole line once, then parse the results.
3006 2002-09-17 Paul D. Smith <psmith@gnu.org>
3008 Fix Bug #940 (plus another bug I found while looking at this):
3010 * read.c (record_target_var): enter_file() will add a new entry if
3011 it's a double-colon target: we don't want to do that in this
3012 situation. Invoke lookup_file() and only enter_file() if it does
3013 not already exist. If the file we get back is a double-colon then
3014 add this variable to the "root" double-colon target.
3016 * variable.c (initialize_file_variables): If this file is a
3017 double-colon target but is not the "root" target, then initialize
3018 the root and make the root's variable list the parent of our
3019 variable list.
3021 2002-09-13 Paul D. Smith <psmith@gnu.org>
3023 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3025 * hash.c (round_up_2): Get rid of a warning.
3027 2002-09-12 Paul D. Smith <psmith@gnu.org>
3029 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3030 so it doesn't complain about getloadavg.c.
3032 * commands.c (set_file_variables): Make sure we always alloca() at
3033 least 1 character for the value of $? (for '\0').
3035 2002-09-11 Paul D. Smith <psmith@gnu.org>
3037 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3038 macro to use RESULT instead of the incorrect _RESULT_.
3040 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3041 and atomic_readdir(). We need to #include dirent.h to get this to
3042 work.
3043 * misc.c (atomic_readdir): Fix typos.
3045 2002-09-10 Paul D. Smith <psmith@gnu.org>
3047 * read.c (eval): Expand variable lists given to export and
3048 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3049 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3051 * doc/make.texi (Variables/Recursion): Document this.
3052 (Conditional Syntax): And here.
3054 2002-09-09 Paul D. Smith <psmith@gnu.org>
3056 * configure.in: Check for memmove().
3058 2002-09-07 Paul D. Smith <psmith@gnu.org>
3060 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3061 Michael Sterrett <msterret@coat.com> reports that while it has
3062 SA_RESTART, it does not work properly.
3064 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3065 that invokes stat() and loops to do it again if it returns EINTR.
3066 (atomic_readdir): Ditto, with readdir().
3068 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3069 and readdir() to atomic_stat() and atomic_readdir().
3071 2002-09-04 Paul D. Smith <psmith@gnu.org>
3073 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3074 reports that GNU make sometimes doesn't recognize that targets can
3075 be made, when directories can be created as prerequisites. He
3076 reports that changing the order of predicates in the DEP->changed
3077 flag test so that lookup_file() is always performed, solves this
3078 problem.
3080 2002-08-08 Paul D. Smith <psmith@gnu.org>
3082 * configure.in: Require a newer version of gettext.
3084 * misc.c (perror_with_name): Translate the format string (for
3085 right-to-left language support).
3086 (pfatal_with_name): Ditto.
3088 * main.c: Create a static array of strings to store the usage
3089 text. This is done to facilitate translations.
3090 (struct command_switch): Remove argdesc and description fields.
3091 (switches): Remove values for obsolete fields.
3092 (print_usage): Print each element of the usage array.
3094 * hash.c: Change function definitions to be K&R style.
3096 2002-08-02 Paul D. Smith <psmith@gnu.org>
3098 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3099 this one because it's too hard to get right. We'll look at it for
3100 a future release.
3101 * main.c (main): Don't create the .TARGETS variable.
3102 * variable.c (handle_special_var): Don't handle .TARGETS.
3104 2002-08-01 Paul D. Smith <psmith@gnu.org>
3106 * main.c (switches): Add a new option, -B (--always-make). If
3107 specified, make will rebuild all targets that it encounters even
3108 if they don't appear to be out of date.
3109 (always_make_flag): New flag.
3110 * make.h: Extern always_make_flag.
3111 * remake.c (update_file_1): Check always_make_flag; if it's set we
3112 will always rebuild any target we can, even if none of its
3113 prerequisites are newer.
3114 * NEWS: Mention it.
3116 * doc/make.texi (Shell Function): Make it clear that make
3117 variables marked as "export" are not passed to instances of the
3118 shell function.
3120 Add new introspection variable .VARIABLES and .TARGETS.
3122 * variable.c (handle_special_var): New function. If the variable
3123 reference passed in is "special" (.VARIABLES or .TARGETS),
3124 calculate the new value if necessary. .VARIABLES is handled here:
3125 walk through the hash of defined variables and construct a value
3126 which is a list of the names. .TARGETS is handled by
3127 build_target_list().
3128 (lookup_variable): Invoke handle_special_var().
3129 * file.c (build_target_list): Walk through the hask of known files
3130 and construct a list of the names of all the ones marked as
3131 targets.
3132 * main.c (main): Initialize them to empty (and as simple variables).
3133 * doc/make.texi (Special Variables): Document them.
3134 * NEWS: Mention them.
3136 * variable.h (struct variable): Add a new flag "exportable" which
3137 is true if the variable name is valid for export.
3138 * variable.c (define_variable_in_set): Set "exportable" when a new
3139 variable is defined.
3140 (target_environment): Use the "exportable" flag instead of
3141 re-checking the name here... an efficiency improvement.
3143 2002-07-31 Paul D. Smith <psmith@gnu.org>
3145 * config.h-vms.template: Updates to build on VMS. Thanks to
3146 Brian_Benning@aksteel.com for helping verify the build.
3147 * makefile.com: Build the new hash.c file.
3148 * hash.h: Use strcpmi(), not stricmp(), in the
3149 HAVE_CASE_INSENSITIVE_FS case.
3151 2002-07-30 Paul D. Smith <psmith@gnu.org>
3153 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3154 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3155 Reported by <Brian_Benning@aksteel.com>.
3157 2002-07-10 Paul D. Smith <psmith@gnu.org>
3159 * variable.c (pop_variable_scope): Remove variable made unused by
3160 new hash infrastructure.
3161 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3162 comparisons as well as name comparisons.
3163 * variable.h: Add a prototype for new hash_init_function_table().
3164 * file.c (lookup_file): Remove variables made unused by new hash
3165 infrastructure.
3166 * dir.c (directory_contents_hash_2): Missing return of hash value.
3167 (dir_contents_file_exists_p): Remove variables made unused by new
3168 hash infrastructure.
3171 Installed Greg McGary's integration of the hash functions from the
3172 GNU id-utils package:
3174 2002-07-10 Greg McGary <greg@mcgary.org>
3176 * scripts/functions/filter-out: Add literals to to the
3177 pattern space in order to add complexity, and trigger
3178 use of an internal hash table. Fix documentation strings.
3179 * scripts/targets/INTERMEDIATE: Reverse order of files
3180 passed to expected `rm' command.
3182 2002-07-10 Greg McGary <greg@mcgary.org>
3184 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3185 * hash.c: New file, taken from id-utils.
3186 * hash.h: New file, taken from id-utils.
3188 * make.h (HASH, HASHI): Remove macros.

3195 (file_hash_enter): Remove function decl.
3196 (init_hash_files): New function decl.
3198 * ar.c (ar_name): Delay call to strlen until needed.
3199 * main.c (initialize_global_hash_tables): New function.
3200 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3201 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3202 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
3204 * dir.c (hash.h): New #include.
3205 (struct directory_contents) [next, files]: Remove members.
3206 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

3208 directory_contents_hash_cmp): New functions.
3209 (directories_contents): Change type to `struct hash_table'.

3216 (find_directory): Use new hash table package.
3217 (dir_contents_file_exists_p): Likewise.
3218 (file_impossible): Likewise.
3219 (file_impossible_p): Likewise.
3220 (print_dir_data_base): Likewise.
3221 (open_dirstream): Likewise.
3222 (read_dirstream): Likewise.
3223 (hash_init_directories): New function.
3225 * file.c (hash.h): New #include.
3226 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
3227 (files): Change type to `struct hash_table'.
3228 (lookup_file): Use new hash table package.
3229 (enter_file): Likewise.
3230 (remove_intermediates): Likewise.
3231 (snap_deps): Likewise.
3232 (print_file_data_base): Likewise.
3234 * function.c
3235 (function_table_entry_hash_1, function_table_entry_hash_2,
3236 function_table_entry_hash_cmp): New functions.
3237 (lookup_function): Remove `table' argument.
3238 Use new hash table package.
3239 (struct a_word) [chain, length]: New members.
3240 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3241 (struct a_pattern): New struct.
3242 (func_filter_filterout): Pass through patterns noting boundaries
3243 and '%', if present. Note a_word length. Use a hash table if
3244 arglists are large enough to justify cost.
3245 (function_table_init): Renamed from function_table.
3246 (function_table): Declare as `struct hash_table'.
3247 (FUNCTION_TABLE_ENTRIES): New constant.
3248 (hash_init_function_table): New function.
3250 * read.c (hash.h): New #include.
3251 (read_makefile): Pass char constants to find_char_unquote.
3252 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3253 (uniquize_deps): Use hash table to efficiently identify duplicates.
3254 (find_char_unquote): Accept two char-constant stop chars, rather
3255 than a string constant, avoiding zillions of calls to strchr.
3256 Tighten inner search loops to test only for desired delimiters.
3258 * variable.c (variable_hash_1, variable_hash_2,
3259 variable_hash_cmp): New functions.
3260 (variable_table): Declare as `struct hash_table'.
3261 (global_variable_set): Remove initialization.

3265 (lookup_variable_in_set): Likewise.
3266 (initialize_file_variables): Likewise.
3267 (pop_variable_scope): Likewise.
3268 (create_new_variable_set): Likewise.
3269 (merge_variable_sets): Likewise.
3270 (define_automatic_variables): Likewise.
3271 (target_environment): Likewise.
3272 (print_variable_set): Likewise.
3274 2002-07-10 Paul D. Smith <psmith@gnu.org>
3276 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3277 prerequisite list. A real SysV make will expand the entire
3278 prerequisites list _twice_: we don't do that as it's a big
3279 backward-compatibility problem. We only replace those specific
3280 variables.
3282 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3283 references left in the list of prerequisites. Check for .POSIX as
3284 we record targets, so we can disable non-POSIX behavior while
3285 reading makefiles as well as running them.
3286 (eval): Check the prerequisite list to see if we have anything
3287 that looks like a SysV prerequisite variable reference.
3289 2002-07-09 Paul D. Smith <psmith@gnu.org>
3291 * doc/make.texi (Prerequisite Types): Add a new section describing
3292 order-only prerequisites.
3294 * read.c (uniquize_deps): If we have the same file as both a
3295 normal and order-only prereq, get rid of the order-only prereq,
3296 since the normal one supersedes it.
3298 2002-07-08 Paul D. Smith <psmith@gnu.org>
3300 * AUTHORS: Added Greg McGary to the AUTHORS file.
3301 * NEWS: Blurbed order-only prerequisites.
3302 * file.c (print_file): Show order-only deps properly when printing
3303 the database.
3305 * maintMakefile: Add "update" targets for wget'ing the latest
3306 versions of various external files. Taken from Makefile.maint in
3307 autoconf, etc.
3309 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3310 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3312 2002-07-07 Paul D. Smith <psmith@gnu.org>
3314 * po/*.po: Remove. We'll use wget to retrieve them at release
3315 time.
3317 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3318 rather than a shell you get an exception. Make sure we look up
3319 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3321 * remake.c (notice_finished_file): Fix handling of -t flag.
3322 Patch provided by Henning Makholm <henning@makholm.net>.
3324 * implicit.c (pattern_search): Some systems apparently run short
3325 of stack space, and using alloca() in this function caused an
3326 overrun. I modified it to use xmalloc() on the two variables
3327 which seemed like they might get large. Fixes Bug #476.
3329 * main.c (print_version): Update copyright notice to conform with
3330 GNU standards.
3331 (print_usage): Update help output.
3333 * function.c (func_eval): Create a new make function, $(eval
3334 ...). Expand the arguments, put them into a buffer, then invoke
3335 eval_buffer() on the resulting string.
3336 (func_quote): Create a new function, $(quote VARNAME). Inserts
3337 the value of the variable VARNAME without expanding it any
3338 further.
3340 * read.c (struct ebuffer): Change the linebuffer structure to an
3341 "eval buffer", which can be either a file or a buffer.
3342 (eval_makefile): Move the code in the old read_makefile() which
3343 located a makefile into here: create a struct ebuffer with that
3344 information. Have it invoke the new function eval() with that
3345 ebuffer.
3346 (eval_buffer): Create a new function that creates a struct ebuffer
3347 that holds a string buffer instead of a file. Have it invoke
3348 eval() with that ebuffer.
3349 (eval): New function that contains the guts of the old
3350 read_makefile() function: this function parses makefiles. Obtains
3351 data to parse from the provided ebuffer. Some modifications to
3352 make the flow of the function cleaner and clearer. Still could
3353 use some work here...
3354 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3355 contents of the define/endef variable from the ebuffer.
3356 (readstring): Read the next line from a string-style ebuffer.
3357 (readline): Read the next line from an ebuffer. If it's a string
3358 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3359 from the file.
3361 * dep.h (eval_buffer): Prototype eval_buffer();
3363 * variable.c (do_variable_definition): Make sure that all
3364 non-target-specific variables are registered in the global set.
3365 If we're invoked from an $(eval ...) we might be inside a $(call
3366 ...) or other function which has pushed a variable scope; we still
3367 want to define our variables from evaluated makefile code in the
3368 global scope.
3370 2002-07-03 Greg McGary <greg@mcgary.org>
3372 * dep.h (struct dep) [ignore_mtime]: New member.
3373 [changed]: convert to a bitfield.
3374 * implicit.c (pattern_search): Zero ignore_mtime.
3375 * main.c (main, handle_non_switch_argument): Likewise.
3376 * rule.c (convert_suffix_rule): Likewise.
3377 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3378 (read_makefile): Parse '|' in prerequisite list.
3379 (uniquize_deps): Consider ignore_mtime when comparing deps.
3380 * remake.c (update_file_1, check_dep): Don't force remake for
3381 dependencies that have d->ignore_mtime.
3382 * commands.c (FILE_LIST_SEPARATOR): New constant.
3383 (set_file_variables): Don't include a
3384 prerequisite in $+, $^ or $? if d->ignore_mtime.
3385 Define $|.
3387 2002-06-18 Paul D. Smith <psmith@gnu.org>
3389 * make.texinfo: Updates for next revision. New date/rev/etc.
3390 Recreate all Info menus. Change license on the manual to the GNU
3391 Free Documentation License. A number of typos.
3392 (Variables Simplify): Don't use "-" before it's defined.
3393 (Automatic Prerequisites): Rewrite the target example to work
3394 properly if the compile fails. Remove incorrect comments about
3395 how "set -e" behaves.
3396 (Text Functions): Move the "word", "wordlist", "words", and
3397 "firstword" functions here, from "File Name Functions".
3398 * make-stds.texi: Update from latest GNU version.
3399 * fdl.texi: (created) Import the latest GNU version.
3401 2002-06-06 Paul D. Smith <psmith@gnu.org>
3403 * variable.c (do_variable_definition): New function: extract the
3404 part of try_variable_definition() that actually sets the value
3405 into a separate function.
3406 (try_variable_definition): Call do_variable_definition() after
3407 parsing the variable definition string.
3408 (define_variable_in_set): Make the name argument const.
3410 * variable.h (enum variable_flavor): Make public.
3411 (do_variable_definition): Create prototype.
3413 * read.c (read_all_makefiles): Create a new built-in variable,
3414 MAKEFILE_LIST.
3415 (read_makefile): Add each makefile read in to this variable value.
3417 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3419 * Makefile.DOS.template: Tweak according to changes in the
3420 distribution. Add back the dependencies of *.o files.
3422 * configh.dos.template: Synchronize with config.h.in.
3424 2002-05-09 Paul D. Smith <psmith@gnu.org>
3426 * file.c (file_timestamp_now): Use K&R function declaration.
3428 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3429 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3430 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3431 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3432 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3433 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3434 nlist.n_name is a pointer rather than an array.
3436 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3437 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3438 * configure.in: Use it instead of the old version.
3440 * main.c (main): Prefer setvbuf() to setlinebuf().
3442 2002-05-08 Paul D. Smith <psmith@gnu.org>
3444 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3445 (loadavg_LDADD): Ditto.
3447 2002-04-29 Paul D. Smith <psmith@gnu.org>
3449 * expand.c (recursively_expand_for_file): Rename
3450 recursively_expand() to recursively_expand_for_file() and provide
3451 an extra argument, struct file. If the argument is provided, set
3452 the variable scope to that of the file before expanding.
3453 * variable.h (recursively_expand): Make this a macro that invokes
3454 recursively_expand_for_file() with a NULL file pointer.
3455 * variable.c (target_environment): Call the renamed function and
3456 provide the current file context.
3457 Fixes Debian bug #144306.
3459 2002-04-28 Paul D. Smith <psmith@gnu.org>
3461 Allow $(call ...) user-defined variables to be self-referencing
3462 without throwing an error. Allows implementation of transitive
3463 closures, among other possibly useful things.
3464 Requested by: Philip Guenther <guenther@sendmail.com>
3466 * variable.h (struct variable): Add a new field: exp_count, and
3467 new macros to hold its size and maximum value.
3468 (warn_undefined): Make this a macro.
3469 * variable.c (define_variable_in_set): Initialize it.
3470 * expand.c (recursively_expand): If we detect recursive expansion
3471 of a variable, check the exp_count field. If it's greater than 0
3472 allow the recursion and decrement the count.
3473 (warn_undefined): Remove this (now a macro in variable.h).
3474 * function.c (func_call): Before we expand the user-defined
3475 function, modify its exp_count field to contain the maximum
3476 number of recursive calls we'll allow. After the call, reset it
3477 to 0.
3479 2002-04-21 Paul D. Smith <psmith@gnu.org>
3481 Modified to use latest autoconf (2.53), automake (1.6.1), and
3482 gettext (0.11.1). We're using gettext's new "external" support,
3483 to avoid including libintl source with GNU make.
3485 * README.cvs: New file. Explain how to build GNU make from CVS.
3487 * configure.in: Modify checking for the system glob library.
3488 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3489 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3490 etc. will manage it correctly). Set an automake conditional
3491 USE_LOCAL_GLOB to decide whether to compile the glob library.
3493 * getloadavg.c (main): Include make.h in the "TEST" program to
3494 avoid warnings.
3496 * Makefile.am: Remove special rules for loadavg. Replace them
3497 with Automake capabilities for building extra programs.
3499 * signame.c: This file does nothing if the system provide
3500 strsignal(). If not, it implements strsignal(). If the system
3501 doesn't define sys_siglist, then we make our own; otherwise we use
3502 the system version.
3503 * signame.h: Removed.
3505 * main.c (main): No need to invoke signame_init(). Update copyright.
3507 * ABOUT-NLS: Removed.
3508 * gettext.c: Removed.
3509 * gettext.h: Get a simplified copy from the gettext package.
3510 * po/*: Created.
3511 * i18n/*.po: Moved to po/.
3512 * i18n/: Removed.
3514 * config/*: Created. Contains package configuration helper files.
3515 * config.guess, config.sub: Moved to config directory.
3517 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3518 Rework to use new-style autoconf features. Use the "external"
3519 mode for gettext. Make the build.sh config file conditional on
3520 whether build.sh.in exists, to avoid autoconf errors.
3521 * acinclude.m4: Removed almost all macros as being obsolete.
3522 Rewrote remaining macros to use AC_DEFINE.
3523 * acconfig.h: Removed.
3525 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3526 conditional to handle customs support. Remove special handling
3527 for i18n features.
3529 2002-04-20 Paul D. Smith <psmith@gnu.org>
3531 * function.c (func_call): Don't mark the argument variables $1,
3532 etc. as recursive. They've already been fully expanded so
3533 there's no need to do it again, and doing so strips escaped $'s.
3534 Reported by Sebastian Glita <glseba@yahoo.com>.
3536 * remake.c (notice_finished_file): Walk through double-colon
3537 entries via the prev field, not the next field!
3538 Reported by Greg McGary <greg@mcgary.org>.
3540 * main.c (main): If the user specifies -q and asks for a specific
3541 target which is a makefile, we got an assert. In that case it
3542 turns out we should continue normally instead.
3544 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3546 * i18n/he.po: Installed a new translation.
3548 2002-01-07 Paul D. Smith <psmith@gnu.org>

3559 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3561 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3562 are available.
3563 (main): Get rid of any avoidable limit on stack size.
3565 2001-09-04 Paul D. Smith <psmith@gnu.org>
3567 * i18n/da.po: Installed an updated translation.
3569 2001-08-03 Paul D. Smith <psmith@gnu.org>
3571 * i18n/fr.po: Installed an updated translation.
3572 Resolves Debian bug #106720.
3574 2001-06-13 Paul D. Smith <psmith@gnu.org>
3576 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3577 translation.
3579 2001-06-11 Paul D. Smith <psmith@gnu.org>
3581 * i18n/ko.po: Installed a new translation.
3583 2001-05-06 Paul D. Smith <psmith@gnu.org>
3585 Modify the EINTR handling.
3587 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3588 the way in which we manage the file descriptor/signal handler race
3589 trap to be more efficient.
3591 2001-05-06 Paul Eggert <eggert@twinsun.com>
3593 Restart almost all system calls that are interrupted, instead
3594 of worrying about EINTR. The lone exception is the read() for
3595 job tokens.
3597 * configure.in (HAVE_SA_RESTART): New macro.
3598 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3599 * main.c (main): Use SA_RESTART instead of the old,
3600 nonstandard SA_INTERRUPT.
3602 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3603 * main.c (bsd_signal): New function or macro,
3604 if the implementation doesn't supply it.
3605 (The bsd_signal function will be in POSIX 1003.1-200x.)
3606 (HANDLESIG): Remove.
3607 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3609 * make.h (EINTR_SET): Remove.
3610 (SA_RESTART): New macro.
3612 * arscan.c (ar_member_touch): Don't worry about EINTR.
3613 * function.c (func_shell): Likewise.
3614 * job.c (reap_children, free_child, new_job): Likewise.
3615 * main.c (main): Likewise.
3616 * remake.c (touch_file, name_mtime): Likewise.
3618 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3619 if fstat failed with errno!=EINTR, the error was ignored.
3621 * job.c (set_child_handler_action_flags): New function.
3622 (new_job): Use it to temporarily clear the SIGCHLD action flags
3623 while reading the token.
3625 2001-05-02 Paul D. Smith <psmith@gnu.org>
3627 * job.c (start_job_command): Don't add define/endef per-line flags
3628 to the top-level flags setting.
3630 2001-04-03 Paul D. Smith <psmith@gnu.org>
3632 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3633 bit on error, so check for odd return values, not non-0 return
3634 values.
3635 (VMS_get_member_info): Calculate the timezone differences correctly.
3636 Reported by John Fowler <jfowler@nyx.net>.
3639 2001-03-14 Paul D. Smith <psmith@gnu.org>
3641 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3642 value before invoking define_variable().
3643 Reported by John Fowler <jfowler@nyx.net>.
3645 2001-02-07 Paul D. Smith <psmith@gnu.org>
3647 * read.c (record_target_var): If we reset the variable due to a
3648 command-line variable setting overriding it, turn off the "append"
3649 flag.
3651 2001-01-17 Paul D. Smith <psmith@gnu.org>
3653 * variable.c (lookup_variable) [VMS]: When getting values from the
3654 environment, allocate enough space for the _value_ plus escapes,
3655 not enough space for the name plus escapes :-/.
3656 Reported by John Fowler <jfowler@nyx.net>.
3658 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3659 warnings that make generates, so it doesn't look like an error.
3660 Reported by Karl Berry <karl@gnu.org>.
3663 Fix for PR/2020: Rework appended target-specific variables. I'm
3664 fairly confident this algorithm is finally correct.
3666 * expand.c (allocated_variable_append): Rewrite. Instead of
3667 expanding each appended variable then adding all the expanded
3668 strings together, we append all the unexpanded values going up
3669 through the variable set contexts, then expand the final result.
3670 This behaves just like non-target-specific appended variable
3671 values, while the old way didn't in various corner cases.
3672 (variable_append): New function: recursively append the unexpanded
3673 value of a variable, walking from the outermost variable scope to
3674 the innermost.
3675 * variable.c (lookup_variable): Remove the code that looked up the
3676 variable set list if the found variable was "append". We don't
3677 need this anymore.
3678 (lookup_variable_in_set): Make this non-static so we can use it
3679 elsewhere.
3680 (try_variable_definition): Use lookup_variable_in_set() rather
3681 than faking out current_variable_set_list by hand (cleanup).
3682 * variable.h: Add a prototype for the now non-static
3683 lookup_variable_in_set().
3685 2000-11-17 Paul D. Smith <psmith@gnu.org>
3687 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3688 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3689 before throwing a fit.
3691 2000-11-17 Paul D. Smith <psmith@gnu.org>
3693 * read.c (readline): CRLF calculations had a hole, if you hit the
3694 buffer grow scenario just right. Reworked the algorithm to avoid
3695 the need for len or lastlen at all. Problem description with
3696 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3698 2000-10-24 Paul D. Smith <psmith@gnu.org>
3700 * gettext.c (SWAP): Declare this with the prototype, otherwise
3701 some systems don't work (non-32-bit? Reported for Cray T3E).
3702 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3704 2000-10-05 Paul D. Smith <psmith@gnu.org>
3706 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3707 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3709 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3711 2000-09-22 Paul D. Smith <psmith@gnu.org>
3713 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3714 parts of the real gettext.h here, and we expect to really include
3715 the real gettext.h later. If we keep this #define, it's ignored.
3717 2000-09-21 Paul D. Smith <psmith@gnu.org>
3719 * main.c (log_working_directory): Rework the text to use complete
3720 sentences, to make life simpler for the translators.
3722 2000-08-29 Paul D. Smith <psmith@gnu.org>
3724 * file.c (remove_intermediates): Print a debug message before we
3725 remove intermediate files, so the user (if she uses -d) knows
3726 what's going on.
3728 2000-08-21 Paul D. Smith <psmith@gnu.org>
3730 * variable.c (try_variable_definition): Change how we handle
3731 target-specific append variable defns: instead of just setting the
3732 value, expand it as an append _but_ only within the current
3733 target's context. Otherwise we lose all but the last value if the
3734 variable is appended more than once within the current target
3735 context. Fixes PR/1831.
3737 2000-08-16 Paul D. Smith <psmith@gnu.org>
3739 * function.c (func_shell): Nul-terminate the buffer before
3740 printing an exec error message (just in case it's not!).
3741 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3743 2000-07-25 Paul D. Smith <psmith@gnu.org>
3745 * job.c (construct_command_argv_internal): Add "~" to the list of
3746 sh_chars[] which disallow optimizing out the shell call.
3748 2000-07-23 Paul Eggert <eggert@twinsun.com>
3750 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3751 supersedes --disable-nsec-timestamps.
3752 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3753 * README: Remove --disable-nsec-timestamps.
3755 * filedef.h (struct file.low_resolution_time): New member.
3756 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3757 * remake.c (update_file_1):
3758 Avoid spurious rebuilds due to low resolution time stamps,
3759 generalizing the earlier code that applied only to archive members.
3760 (f_mtime): Archive members always have low resolution time stamps.
3762 * configure.in: Remove --disable-nsec-timestamps, as this has
3763 been superseded by .LOW_RESOLUTION_TIME.
3765 2000-07-23 Paul Eggert <eggert@twinsun.com>
3767 * configure.in (enable_nsec_timestamps): Renamed from
3768 make_cv_nsec_timestamps, since enable/disable options
3769 shouldn't be cached.
3771 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3772 and Paul Eggert <eggert@twinsun.com>
3774 * file.c (file_timestamp_now):
3775 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3776 so that clock_gettime is not linked unless needed.
3778 * filedef.h (FILE_TIMESTAMP_HI_RES):
3779 Remove definition; "configure" now does this.
3781 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3782 to before high resolution file timestamp check,
3783 since that check now uses uintmax_t.
3784 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3785 high resolution file timestamps.
3786 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3787 so that we don't link in clock_gettime unnecessarily.
3789 2000-07-17 Paul D. Smith <psmith@gnu.org>
3791 * i18n/ja.po: New version of the translation file.
3793 2000-07-07 Paul D. Smith <psmith@gnu.org>
3795 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3796 the offset calculation.
3797 (name_mtime): Replace EINTR test with EINTR_SET macro.
3799 2000-07-07 Paul Eggert <eggert@twinsun.com>
3801 Fix for PR/1811:
3803 * remake.c (update_file_1):
3804 Avoid spurious rebuilds of archive members due to their
3805 timestamp resolution being only one second.
3806 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3807 the clock's resolution being lower than file timestamps'.
3808 When warning about future timestamps, report only the discrepancy,
3809 not the absolute value of the timestamp and the current time.
3811 * file.c (file_timestamp_now): New arg RESOLUTION.
3812 * filedef.h (file_timestamp_now): Likewise.
3813 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3815 2000-07-05 Paul D. Smith <psmith@gnu.org>
3817 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3818 to listp. Fixes PR/1793.
3820 2000-06-26 Paul Eggert <eggert@twinsun.com>
3822 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3824 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3826 * remake.c (f_mtime): Remove unused var memtime.
3828 2000-06-25 Martin Buchholz <martin@xemacs.org>
3830 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3831 Ran spell-check on make.texinfo.
3833 2000-06-23 Paul D. Smith <psmith@gnu.org>
3835 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3836 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3837 * make.h: Define these macros.
3839 * Version 3.79.1 released.
3841 * configure.in: Add a new option, --disable-nsec-timestamps, to
3842 avoid using sub-second timestamps on systems that support it. It
3843 can lead to problems, e.g. if your makefile relies on "cp -p".
3844 * README.template: Document the issue with "cp -p".
3846 * config.guess, config.sub: Updated.
