36 * make.h (vpath_search): Update prototype.
38 * remake.c (library_search): Implement linker-compatible library
39 search. Use the new VPATH_SEARCH index functionality to keep track

61 * main.c (usage): Add --eval to the usage string.
62 (switches): Add the --eval switch.

96 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
97 to normal upgrade logic from dep_hash_cmp to set_file_variables.
99 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
101 * dep.h (uniquize_deps): Remove.
103 * read.c (uniquize_deps): Merge into set_file_variables in
104 commands.c.
105 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
107 * commands.c (set_file_variables): Avoid modifying the dep
108 chain to achieve uniqueness. Fixes savannah bug 25780.
110 * implicit.c (pattern_search): Instead of re-setting all automatic
111 variables for each rule we try, just update $*.
113 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
115 * variable.h (undefine_variable_in_set): New function declaration.
116 (undefine_variable_global): New macro.

131 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
133 * implicit.c (pattern_search): Initialize file variables only
134 if we need to parse a rule that requires the second expansion.
136 2009-10-03 Paul Smith <psmith@gnu.org>
138 * make.h: Include <alloca.h> even on systems where __GNUC__ is
139 defined. Not sure why it was done the other way.
140 Requested by David Boyce <dsb@boyski.com>.
142 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>

146 * filedef.h (file):Add the NO_DIAG bitfield.
148 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
149 not struct file (a file can be a dependency of many targets,
150 some don't care, some do).
152 * remake.c (update_goal_chain): Propagate DONTCARE from struct
153 dep to struct file before updating the goal and restore it
154 afterwards.
155 (update_file): Don't prune the dependency graph if this target
156 has failed but the diagnostics hasn't been issued.
157 (complain): Scan the file's dependency graph to find the file
158 that caused the failure.
159 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
160 whether to print diagnostics.

164 2009-09-28 Paul Smith <psmith@gnu.org>
166 * doc/make.texi (Pattern Intro): Move the match algorithm
167 discussion into the "Pattern Match" node.

170 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
172 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
173 much of the command line on a single pass.
175 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
177 * varible.c (create_pattern_var): Insert variables into the
178 PATTERN_VARS list in the shortest patterns first order.
180 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are

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

195 2009-09-27 Paul Smith <psmith@gnu.org>
197 * doc/make.texi (Double-Colon): Mention that pattern rules with
198 double-colons have a different meaning. Savannah bug #27497.
200 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
202 * configh.dos.template: Remove unconditional definition of
203 SYS_SIGLIST_DECLARED.
204 Include <sys/version.h> because ports of GCC 4.3.0 and later no
205 longer include it, so macros like __DJGPP_MINOR__ are no longer
206 defined automatically.
208 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
209 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
210 instead of using the hardcoded ones.
211 (SUBDIRS): doc subdir added.
212 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
213 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
214 create html formated docs. texi2html may not be ported to DOS.
215 (make.info, make.dvi, make.ps, make.html): Make targets depend on
216 'make.texi'.
217 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
218 -I switch to look in ./ instead of ./doc.
219 (html): Target depend on html-recursive instead of make_1.html.
220 (make_1.html): Removed.
221 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
222 (all-recursive): Allow for more than one subdir in the build
223 process.
224 (mostlyclean-recursive, clean-recursive, distclean-recursive)
225 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
226 (tags-recursive): Allow for more than one subdir in the build
227 process.
228 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
229 targets. Enter into doc/ to produce the targets.
230 (all-am): $(INFO_DEPS) replaced by info.
232 2009-09-26 Paul Smith <psmith@gnu.org>
234 * read.c (record_files): Use free_ns() to free struct nameseq.
235 (eval): Ditto.
237 * rule.c (freerule): Use free_dep_chain().
239 * read.c (record_files): Free FILENAMES chain for implicit rules.
240 (eval): Static pattern targets go into the string cache.
242 * function.c (string_glob): Free NAME in the nameseq chain.
244 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
246 * implicit.c (pattern_search): Terminate early if we haven't
247 found any rules to try (performance improvement).
249 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
251 * implicit.c (pattern_search): Merge three parallel arrays,
252 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
253 of struct TRYRULE. In the old version the latter two arrays
254 had insufficient length.
256 2009-09-24 Paul Smith <psmith@gnu.org>
258 * implicit.c (pattern_search): Add back support for order-only
259 prerequisites for secondary expansion implicit rules, that were
260 accidentally dropped. If we find a "|", enable order-only mode
261 and set IGNORE_MTIME on all deps that are seen afterward.
262 (pattern_search): Fix memory leaks: for intermediate files where
263 we've already set the file variable and pattern variable sets, be
264 sure to either save or free them as appropriate.
266 2009-09-23 Paul Smith <psmith@gnu.org>
268 Rework the way secondary expansion is stored, for efficiency.
269 This changes secondary expansion so that ONLY WHEN we know we have
270 a possibility of needing secondary expansion, do we defer the
271 secondary expansion. This means more parsing the deps but we use
272 a lot less memory (due to the strcache). Also, this fixes
273 Savannah bug #18622.
275 * read.c (eval): Don't parse the dep string here anymore.
276 (record_files): Take the dep argument as an unparsed string. If
277 secondary expansion is enabled AND the prereq string has a '$' in
278 it, then set NEED_2ND_EXPANSION and keep the entire string.
279 Otherwise, parse the dep string here to construct the dep list
280 with the names in the strcache.
282 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
283 duplicate the name string (others are in the strcache).
285 * implicit.c: Remove struct idep and free_idep_chain(): unused.
286 (struct patdeps): New structure to store prereq information.
287 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
288 which prerequisites need expansion, and expand only those.
290 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
291 and enter_prereqs(). split_prereqs() takes a fully-expanded string
292 and splits it into a DEP list, handling order-only prereqs.
293 (enter_prereqs): This function enters a list of DEPs into the file
294 database. If there's a stem defined, expand any pattern chars.
295 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
296 set. Use the above functions.
297 (snap_deps): Only perform second expansion on prereqs that need it,
298 as defined by the NEED_2ND_EXPANSION flag.
299 (print_prereqs): New function to print the prereqs
300 (print_file): Call print_prereqs() rather than print inline.
302 * hash.h (STRING_COMPARE): Take advantage of strcache() by
303 comparing pointers.
304 (STRING_N_COMPARE): Ditto.
305 (ISTRING_COMPARE): Ditto.
307 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
308 (parse_file_seq): Return void*
309 * read.c (parse_file_seq): Return void*.
310 (eval): Invoke macroized version of parse_file_seq()
311 * default.c (set_default_suffixes): Ditto.
312 * file.c (split_prereqs): Ditto.
313 * function.c (string_glob): Ditto.
314 * main.c (main): Ditto.
315 * rule.c (install_pattern_rule): Ditto.
317 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
319 2009-09-16 Paul Smith <psmith@gnu.org>
321 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
322 convert to macros.
323 * dep.h: Create alloc_dep() / free_dep() macros.
325 * implicit.c (pattern_search): Take advantage of the new
326 parse_file_seq() to add the directory prefix to each prereq.
328 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
329 all. Avoid reversing chains. Support adding prefixes.
330 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
331 cached/non-cached results.
332 (eval): Remove multi_glob() & invoke new parse_file_seq().
333 * rule.c (install_pattern_rule): Ditto.
334 * main.c (main): Ditto.
335 * implicit.c (pattern_search): Ditto.
336 * function.c (string_glob): Ditto.
337 * file.c (parse_prereqs): Ditto.
338 * default.c (set_default_suffixes): Ditto.
340 * variable.c (parse_variable_definition): Don't run off the end of
341 the string if it ends in whitespace (found with valgrind).
343 * commands.c (set_file_variables): Keep space for all targets in
344 $? if -B is given (found with valgrind).
346 2009-09-15 Paul Smith <psmith@gnu.org>
348 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
349 (xcalloc): Add new function.
350 * make.h: New declarations.
352 * ar.c (ar_glob_match): New calling method for concat().
353 * main.c (main): Ditto.
354 (decode_env_switches): Ditto.
355 * read.c (eval_makefile): Ditto.
356 (tilde_expand): Ditto.
357 (parse_file_seq): Ditto.
358 * variable.c (target_environment): Ditto.
359 (sync_Path_environment): Ditto.
361 * ar.c (ar_glob_match): Use xcalloc().
362 * dir.c (file_impossible): Ditto.
363 * file.c (enter_file): Ditto.
364 * job.c (new_job): Ditto.
365 * read.c (parse_file_seq): Ditto.
366 * vmsfunctions.c (opendir): Ditto.
368 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
370 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
371 inside the loop that looks up environment for PATH.
373 2009-08-31 Eli Zaretskii <eliz@gnu.org>
375 * function.c (windows32_openpipe): Update envp after calling
376 sync_Path_environment.
378 2009-08-02 Paul Smith <psmith@gnu.org>
380 * remake.c (notice_finished_file): Ensure file->cmds is not null
381 before looping through them. Fixes Savannah bug #21824.
383 * doc/make.texi (Wildcard Examples): Clarify when objects is
384 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
385 (Include): Clarify the behavior of -include.
386 Fixes Savannah bug #18963.
388 2009-08-01 Paul Smith <psmith@gnu.org>
390 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
391 etc. come on the command line. Fixes Savannah bug #27093.
393 * expand.c (expand_argument): If the argument is large enough use
394 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
396 * variable.c (do_variable_definition): Avoid using alloca() to
397 hold values, which can be large. Fixes Savannah bug #23960.
399 * job.c (new_job): Use memmove() instead of strcpy() since both
400 pointers are in the same memory block. Fixes Savannah bug #27148.
401 Patch by Petr Machata.
403 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
405 * job.c (construct_command_argv_internal): Add "ulimit" and
406 "unset" to the sh_cmds for Unixy shells.
408 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
410 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
411 that set make_cv_sys_gnu_glob, so they are also correctly set
412 when the cache has been populated before.
414 2009-07-04 Eli Zaretskii <eliz@gnu.org>
416 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
417 exist, as realpath(3) does where it's supported.
419 2006-07-04 Eli Zaretskii <eliz@gnu.org>
421 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
422 (abspath): Support systems that define HAVE_DOS_PATHS (have
423 drive letters in their file names). Use IS_PATHSEP instead of a
424 literal '/' comparison. Fixes Savannah bug #26886.
426 2009-06-14 Paul Smith <psmith@gnu.org>
428 * remake.c (update_file_1): Remember the original file we marked
429 as updating, so we can clear that flag again. If we find a target
430 via vpath, FILE might change.
431 (check_dep): Ditto. Fixes Savannah bug #13529.
432 Patch by Reid Madsen <reid.madsen@tek.com>.
434 2009-06-13 Paul Smith <psmith@gnu.org>
436 * doc/make.texi (MAKEFILES Variable): Be explicit that files
437 included by MAKEFILES cannot give default goals.
438 * read.c (eval): If set_default is not set, pass the no-default-goal
439 value when we read included makefiles. Fixes Savannah bug #13401.
441 * ar.c (ar_name): Ensure that targets with empty parens aren't
442 considered archive member references: archive members must have a
443 non-empty "member" string. Fixes Savannah bug #18435.
445 * function.c (string_glob): Rely on multi_glob() to determine
446 whether files exist or not. Remove call to file_exists_p() which
447 is not always correct. Fixes Savannah bug #21231.
448 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
449 then only files that really exist will be returned.
450 * dep.h: Add new argument to multi_glob().
451 * rule.c (install_pattern_rule): Ditto.
452 * read.c (eval): Ditto.
453 * main.c (main): Ditto.
454 * implicit.c (pattern_search): Ditto.
455 * file.c (parse_prereqs): Ditto.
456 * default.c (set_default_suffixes): Ditto.
458 2009-06-09 Paul Smith <psmith@gnu.org>
460 * commands.c (set_file_variables): If always_make_flag is set,
461 always add the prereq to $?. Fixes Savannah bug #17825.
463 * remake.c (update_file_1): When rebuilding deps of FILE, also try
464 to rebuild the deps of all the also_make targets for that file.
465 Fixes Savannah bug #19108.
467 * implicit.c (pattern_search): Undo test for is_target, added by
468 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
469 Rule Search Algorithm". Fixes Savannah bug #17752.
471 * main.c (clean_jobserver): Clear the jobserver_fds options and
472 set job_slots to the default when we clean up.
473 (define_makeflags): Return the new MAKEFLAGS value.
474 (main): Reset MAKEFLAGS in the environment when we re-exec.
475 Fixes Savannah bug #18124.
477 2009-06-08 Paul Smith <psmith@gnu.org>
479 * read.c (eval): Collapse continuations post-semicolon on target-
480 specific variables. Fixes Savannah bug #17521.
482 2009-06-07 Paul Smith <psmith@gnu.org>
484 * job.c (reap_children): For older systems without waitpid() (are
485 there any of these left?) run wait(2) inside EINTRLOOP to handle
486 EINTR errors. Fixes Savannah bug #16401.
488 * (various): Debug message cleanup. Fixes Savannah bug #16469.
490 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
492 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
493 not the end, to catch second expansion $(eval ...) defining new
494 target/prereq relationships during snap_deps.
495 Fixes Savannah bug #24622.
497 * read.c (record_files): The second-expansion "f->updating" hack
498 was not completely correct: if assumed that the target with
499 commands always had prerequisites; if one didn't then the ordering
500 was messed up. Fixed for now to use f->updating to decide whether
501 to preserve the last element in the deps list... but this whole
502 area of constructing and reversing the deps list is too confusing
503 and needs to be reworked. Fixes Savannah bug #21198.
505 2009-06-06 Paul Smith <psmith@gnu.org>
507 * hash.c (hash_insert): Remove useless test for NULL.
508 Fixes Savannah bug #21823.
510 * make.h: Move SET_STACK_SIZE determination to make.h.
511 * main.c (main): New global variable, STACK_LIMIT, holds the
512 original stack limit when make was started.
513 * job.c (start_job_command): Reset the stack limit, if we changed it.
514 Fixes Savannah bug #22010.
516 * remake.c (check_dep): Only set the target's state to not-started
517 if it's not already running. Found this while testing -j10 builds
518 of glibc: various targets were being rebuilt multiple times.
519 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
520 bug #15919.
522 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
523 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
524 Bugzilla bug 10246.
526 2009-06-04 Paul Smith <psmith@gnu.org>
528 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
530 * maintMakefile: Modify access of config and gnulib Savannah
531 modules to use GIT instead of CVS.
533 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
534 Fixes Savannah bug #24655.
536 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
537 this can happen during some invocations of $(eval ...) for example.
538 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
540 2009-06-02 Paul Smith <psmith@gnu.org>
542 * configure.in: Check for fileno()
543 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
544 for the makefile file so invocations of $(shell ...) don't inherit it.
545 Fixes Savannah bug #24277.
547 2009-06-01 Paul Smith <psmith@gnu.org>
549 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
550 expansion was handled incorrectly. Rework the default goal
551 handling to save the variable only. Remove default_goal_file and
552 default_goal_name.
553 * read.c (eval): Check default_goal_var, not default_goal_name.
554 * read.c (record_target_var): Don't check default_goal_file here.
556 2009-05-31 Paul Smith <psmith@gnu.org>
558 * main.c (main): Expand the .DEFAULT_GOAL variable before using
559 it, and if the multi_glob() returns nothing (say it expanded to
560 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
562 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
563 $(and ..) to the reference. Fixes Savannah bug #25694.
565 * make.1: Be clear that some recipes will be executed even with -n.
566 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
568 * doc/make.texi (Override Directive): Make more clear how
569 overrides and appends interact.
570 Elucidates part of Savannah bug #26207.
572 * read.c (record_target_var): Don't reset the origin on
573 target-specific variables; try_variable_definition() will handle
574 this correctly. Fixes Savannah bug #26207.
576 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
577 Fixes Savannah bug #25712.
579 * implicit.c (pattern_search): Keep a pointer to the beginning of
580 the filename and save that instead of the constructed pointer.
581 Fixes Savannah bug #26593.
582 Patch by Mark Seaborn <mrs@mythic-beasts.com>
584 2009-05-30 Paul Smith <psmith@gnu.org>
586 * doc/make.texi (Multi-Line): Add a description of the new abilities
587 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
588 "command sequence" vs. "recipe" syntax.
589 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
590 after a define, to create variables with those flavors.
592 2009-05-25 Paul Smith <psmith@gnu.org>
594 Reworked the parser for variable assignments to allow multiple
595 modifiers, and in any order. Also allows variable and
596 prerequisites to be modifier names ('export', 'private', etc.)
598 * NEWS: Add notes about user-visible changes.
600 * read.c (struct vmodifiers): Remember what modifiers were seen.
601 (parse_var_assignment): New function to parse variable assignments.
602 (eval): Call the new function. Handle variable assignments earlier.

605 (assign_variable_definition): Call parse, then create the var.
607 2009-05-24 Paul Smith <psmith@gnu.org>
609 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
610 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.

618 prototype for xmalloc.
619 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
620 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
621 Loop over an array of extensions, instead of duplicating the same
622 code inline. Use SearchPath followed by CreateFile, instead of
623 the obsolete OpenFile. Fixes Savannah bug #17277.
624 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
625 to `find_file'. Fixes Savannah bug #25662.
627 2009-03-07 Eli Zaretskii <eliz@gnu.org>
629 * function.c (func_shell): Don't close pipedes[1] if it is -1.
630 Fixes Savannah bug #20495.
632 2009-02-28 Ralf Wildenhues <address@hidden>
634 * doc/make.texi (Instead of Execution): Document interaction of
635 -t with phony targets.
637 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
639 Introduce a new keyword "private" which applies to target-specific
640 variables and prevents their values from being inherited.

674 of the batch file.
676 2008-05-31 Eli Zaretskii <eliz@gnu.org>
678 * README.W32.template: Remove obsolete text about non-support for
679 -jN without Unixy shell. Remove obsolete text about not supplying
680 Visual Studio project files (we do supply them). Modify text to
681 prefer GCC builds to MSC builds.
683 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
685 * doc/make.texi (Empty Targets): Fix typo.

700 `value' field is NULL.
702 2007-12-22 Eli Zaretskii <eliz@gnu.org>
704 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:

707 (TEXINFOS): Value changed to `doc/make.texi'.
708 (.SUFFIXES): Use .texi instead of .texinfo.
709 (make.info, make.dvi): Depend on doc/make.texi.
710 (.texi.info): New target, instead of ".texinfo.info". Change -I
711 switch to $(MAKEINFO) to look in doc/. Use --no-split.

713 $(MAKEINFO) to look in doc/. Use --no-split.
714 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
715 switch to $(MAKEINFO) to look in doc/.
716 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
717 "*.i[0-9][0-9]" (due to --no-split above).
718 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
719 (html, make_1.html): New targets.
720 (.PHONY): Add "html".
721 (.SUFFIXES): Add .html.
723 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
725 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
726 HAVE_DECL_SYS_SIGLIST.
728 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
729 build does not use child_execute_job.
731 * variable.c (define_automatic_variables) [__MSDOS__]: Always
732 export the SHELL environment variable to the child.
734 2007-12-22 Eli Zaretskii <eliz@gnu.org>
736 * config.h.W32: Include sys/types.h.
737 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
739 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
740 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
741 also `:'.
743 2007-11-04 Paul Smith <psmith@gnu.org>
745 * doc/make.texi: Convert references to "commands", "command
746 lines", and "command script" to "recipe".

749 Ditto.
751 2007-10-27 Bruno Haible <bruno@clisp.org>
753 * remake.c (f_mtime): Print time difference values between 100 and
754 ULONG_MAX in fixed-point notation rather than in exponention notation.
756 2007-10-12 Eli Zaretskii <eliz@gnu.org>
758 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
759 a more complex value than a simple shell: if it's not a default
760 shell now then expand it and see if is a default shell then.
762 2007-10-10 Eli Zaretskii <eliz@gnu.org>
764 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
765 pathnames, with const strings.
766 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
767 from the template (used for building from CVS, not a dist).
769 2007-10-10 Paul Smith <psmith@gnu.org>
771 * make.h: Add a prototype for w32_kill() (change suggested by

786 2007-09-11 Paul Smith <psmith@gnu.org>
788 * doc/make.texi (Special Variables): Moved this into the "How to
789 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
790 (MAKEFILE_LIST) No longer a section; this was added into the
791 "Special Variables" section.
792 (Rule Introduction): Reference .RECIPEPREFIX.
793 (Simple Makefile): Ditto.
794 (Rule Syntax): Ditto.
795 (Command Syntax): Ditto.
796 (Error Messages): Ditto.
798 2007-09-10 Paul Smith <psmith@gnu.org>
800 * commands.c (print_commands): Don't print an extra line in the
801 command scripts. Prefix the command scripts with cmd_prefix, not \t.
803 * read.c (construct_include_path): Add the full string to the cache; we
804 were chopping the last char.
806 * NEWS: Announce the .RECIPEPREFIX special variable.
807 * variable.c (lookup_special_var): Rename from handle_special_var().
808 (lookup_variable): Call the new name.

810 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
811 (do_variable_definition): Call it.
812 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
813 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
814 * main.c (main): Create the .RECIPEPREFIX special variable.
815 * read.c (eval): Remove the cmd_prefix characters from the command
816 scripts here, so they're not stored in the commands array at all,
817 rather than waiting and stripping them out during command construction.
818 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
820 2007-08-15 Paul Smith <psmith@gnu.org>
822 * doc/make.texi (GNU Free Documentation License): The fdl.texi
823 file has had the section info removed, so add some to make.texi
824 before we include it.
826 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
828 * remake.c (check_dep): Reset the target state for intermediate
829 files. They might have been considered before but not updated

833 2007-07-21 Eli Zaretskii <eliz@gnu.org>
835 Fix Savannah bug #20549:
836 * function.c (func_shell): Call construct_command_argv with zero
837 value of FLAGS.
838 * job.c (construct_command_argv_internal): New argument FLAGS; all
839 callers changed.
840 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
841 just_print_flag.
842 * job.h (construct_command_argv_internal): Update prototype.
844 2007-07-13 Paul Smith <psmith@gnu.org>
846 * file.c (expand_deps): Use variable_buffer as the start of the
847 buffer, not the original pointer (in case it was reallocated).
848 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
849 Fixes Savannah bug #20452.
851 2007-07-04 Paul Smith <psmith@gnu.org>
853 * (ALL FILES): Update to GPLv3.
854 * (ALL FILES): Update copyright for 2007.

872 2007-05-11 Paul Smith <psmith@gnu.org>
874 * job.c (new_job): Add debug info to specify where make found the
875 command script it is running to build a target.
876 Fixes Savannah bug #18617.
878 * default.c (default_suffixes,default_suffix_rules,default_variables):
879 Add support for Objective C. Fixes Savannah bug #16389.
880 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
882 * function.c (func_lastword): Initialize p.
884 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
885 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
886 Dave Korn <dave.korn@artimi.com>
888 2007-05-08 Paul Smith <psmith@gnu.org>
890 Fix Savannah bug #19656:
892 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
894 * make.h: Change all case-insensitive string compares to use
895 strcasecmp() (from POSIX). If we don't have that but do have one
896 of the others, define strcasecmp to be one of those instead. If
897 we don't have any, declare a prototype for our own version.
899 * misc.c (strcasecmp): Use this if we can't find any native
900 case-insensitive string comparison function.
901 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
902 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
903 strcmpi().
904 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
905 strcasecmp() instead of stricmp().
906 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
907 instead of strcmpi().
908 * acinclude.m4: Remove the strcasecmp() check from here.
910 2007-03-21 Paul Smith <psmith@gnu.org>
912 * configure.in: Don't turn on case-insensitive file system support
913 if --disable-... is given. Fixes Savannah bug #19348.
915 2007-03-19 Paul Smith <psmith@gnu.org>
917 * ALL: Use the strcache for all file name strings, or other
918 strings which we will never free. The goal is to save memory by
919 avoiding duplicate copies of strings. However, at the moment this
920 doesn't save much memory in most situations: due to secondary
921 expansion we actually save prerequisite lists twice (once before
922 the secondary expansion, and then again after it's been parsed
923 into individual file names in the dep list). We will resolve this
924 in a future change, by doing the parsing up-front for targets
925 where secondary expansion is not set.
927 Moving things into the strcache also allows us to use const
928 pointers in many more places.
930 2007-01-03 Paul Smith <psmith@gnu.org>
932 * make.h (ENULLLOOP): Reset errno after each failed invocation of
933 the function, not just the first. Fixes Savannah bug #18680.
935 2006-11-18 Paul Smith <psmith@gnu.org>
937 * strcache.c (strcache_add_len): Don't allocate a new buffer
938 unless the string is not already nil-terminated. Technically this
939 is a violation of the standard, since we may be passed an array
940 that is not long enough to test one past. However, in make this
941 is never true since we only use nil-terminated strings or
942 sub-strings thereof.
944 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
946 * main.c: New global cmd_prefix, defaults to '\t'.
947 * job.c (construct_command_argv_internal): Use cmd_prefix instead
948 of '\t'.
950 * dir.c: Constified.
951 (dir_contents_file_exists_p): Check for an error return from
952 readdir(), just in case.
954 * commands.c: Constified.
955 * default.c: Constified.
956 * expand.c: Constified.
957 * function.c: Partial constification.
958 * variable.c: Partial constification.
959 * vmsify.c: Constification. Hard to test this but I hope I didn't
960 screw it up!
961 * vpath.c: Partial constification.
962 * w32/pathstuff.c: Partial constification.
964 2006-11-16 Eli Zaretskii <eliz@gnu.org>
966 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
967 backslashes and drive letters as absolute.
969 2006-10-22 Paul Smith <psmith@gnu.org>
971 * main.c (struct command_switch): Use const and void*.
973 2006-10-21 Paul Smith <psmith@gnu.org>
975 * ar.c: Constified.
976 * arscan.c: Constified.
978 2006-09-30 Paul Smith <psmith@gnu.org>
980 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
981 point to lastword since the example was updated.
982 Fixes Savannah bug #16304.
983 (Secondary Expansion): Correct example description.
984 Fixes Savannah bug #16468.
985 (Makefile Contents): Clarify that comments cannot appear within
986 variable references or function calls.
987 Fixes Savannah bug #16577.
988 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
989 Fixes Savannah bug #17701.
990 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
991 (Prerequisite Types): Added an example of using order-only
992 prerequisites. Fixes Savannah bug #17880.
993 (Rule Syntax): "lise" -> "list"
994 (Multiple Rules): ... -> @dots{}
995 (Splitting Lines): ditto.
997 * remake.c (update_file_1): Prereqs that don't exist should be
998 considered changed, for the purposes of $?.
999 Fixes Savannah bug #16051.

1002 Fixes Savannah bug #16652.
1004 2006-09-06 Paul D. Smith <psmith@gnu.org>
1006 * configure.in: Include sys/types.h when checking for sys/wait.h.
1008 2006-08-18 Eli Zaretskii <eliz@gnu.org>
1010 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1011 $PATH_SEPARATOR.
1013 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1014 Normally, it is defined in config.h.
1016 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1017 well.
1019 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1020 sh_chars_sh for Windows platforms that emulate Unix.
1022 2006-05-07 Paul D. Smith <psmith@gnu.org>
1024 * README.OS2.template: Updates provided by Andreas Buening
1025 <andreas.buening@nexgo.de>.
1027 2006-04-30 Paul D. Smith <psmith@gnu.org>
1029 * make.h: Include <direct.h> if HAVE_DIRECT_H.
1030 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
1032 2006-04-26 Paul D. Smith <psmith@gnu.org>
1034 * README.cvs: Add a reminder to notify the GNU translation robot.

1052 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1053 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1054 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1055 values from memory allocation functions: they return void* and so
1056 don't need to be cast. Also remove (char *) casts of arguments to
1057 xrealloc().
1059 * configure.in: Remove checks for memcpy/memmove/strchr.
1061 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
1063 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp

1067 * variable.c, vpath.c: Ditto.
1069 * make.h (EXIT_FAILURE): Should be 1, not 0.
1071 2006-04-06 Paul D. Smith <psmith@gnu.org>
1073 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1074 require an ISO C 1989 standard compiler and runtime library.
1076 * Makefile.am: Remove the ansi2knr feature.
1078 * make.h: Remove the PARAMS() macro definition and all uses of it.
1080 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
1081 * commands.c, commands.h, config.h-vms.template: Ditto.

1084 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
1086 * NEWS: Update.
1088 2006-04-01 Paul D. Smith <psmith@gnu.org>
1090 Version 3.81 released.
1092 * NEWS: Updated for 3.81.
1094 * README.cvs: Mention that vpath builds are not supported out of
1095 CVS. Fixes Savannah bug #16236.
1096 Remove update of make.texi from the list of things to do; we use
1097 version.texi now.
1099 2006-03-26 Paul D. Smith <psmith@gnu.org>
1101 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1102 support from automake, as described in the Texinfo manual.
1104 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1106 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1107 with lastslash, since the latter points to filename, not to
1108 target.
1109 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1110 Declare and define sh_chars_sh[].
1112 2006-03-23 Paul D. Smith <psmith@gnu.org>
1114 * configure.in: Look for build.sh.in in $srcdir so it will be
1115 built for remote configurations as well.
1117 * Makefile.am: Make sure to clean up build.sh during distclean.
1118 Fixes Savannah bug #16166.
1120 * misc.c (log_access): Takes a const char *.
1121 * function.c (fold_newlines): Takes an unsigned int *.
1122 Both fixes for Savannah bug #16170.
1124 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1126 * implicit.c (pattern_search): Call set_file_variables only
1127 if we have prerequisites that need second expansion. Fixes
1128 Savannah bug #16140.
1130 2006-03-19 Paul D. Smith <psmith@gnu.org>
1132 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1133 memory on hosts that don't support it directly.
1135 * README.cvs: Add information on steps for making a release (to
1136 make sure I don't forget any).
1138 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1139 function.
1140 (die): Cleanup code was removed from here; call the new function.
1141 (main): If we are re-execing, clean up the jobserver first so we
1142 don't leak file descriptors.
1143 Reported by Craig Fithian <craig.fithian@citigroup.com>
1145 2006-03-17 Paul D. Smith <psmith@gnu.org>
1147 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1148 allow multiple concurrent runs.
1149 Patch from Joseph Myers <joseph@codesourcery.com>
1151 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1153 * dep.h (struct dep): Add the stem field.
1154 * misc.c (alloc_dep, free_dep): New functions.
1155 (copy_dep_chain): Copy stem.
1156 (free_dep_chain): Use free_dep.
1157 * read.c (record_files): Store stem in the dependency line.
1158 * file.c (expand_deps): Use stem stored in the dependency line. Use
1159 free_dep_chain instead of free_ns_chain.
1160 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1161 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1162 * main.c (main, handle_non_switch_argument): Ditto.
1163 * remake.c (check_dep): Ditto.
1164 * rule.c (convert_suffix_rule, freerule): Ditto.
1166 2006-03-14 Paul D. Smith <psmith@gnu.org>
1168 * expand.c (variable_append): Instead of appending everything then
1169 expanding the result, we expand (or not, if it's simple) each part
1170 as we add it.
1171 (allocated_variable_append): Don't expand the final result.
1172 Fixes Savannah bug #15913.
1174 2006-03-09 Paul Smith <psmith@gnu.org>
1176 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1177 listed non-existent files as changed. Turns out there's a bug in
1178 the Linux kernel builds which means that this change causes
1179 everything to rebuild every time. We will re-introduce this fix
1180 in the next release, to give them time to fix their build system.
1181 Fixes Savannah bug #16002.
1182 Introduces Savannah bug #16051.
1184 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1185 we *don't* find UNIX "/".
1186 Reported by David Ergo <david.ergo@alterface.com>
1188 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1190 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1191 locator function find_and_set_default_shell if SHELL came from the
1192 command line.
1194 2006-02-20 Paul D. Smith <psmith@gnu.org>
1196 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1197 to be null; don't core in that case.
1199 2006-02-19 Paul D. Smith <psmith@gnu.org>
1201 * commands.c (set_file_variables): Realloc, not malloc, the static
1202 string values to avoid memory leaks.
1204 * expand.c (recursively_expand_for_file): Only set reading_file to
1205 an initialized value.
1207 * implicit.c (pattern_search): We need to make a copy of the stem
1208 if we get it from an intermediate dep, since those get freed.
1210 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1211 begin with ".".
1212 (enter_file) [VMS]: Ditto.
1213 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1215 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1217 * job.c (construct_command_argv_internal): Fix last change.
1219 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1220 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1221 the calls to _beginthreadex.
1223 * expand.c (recursively_expand_for_file): Initialize `save' to
1224 prevent compiler warnings.
1226 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1228 * job.c (construct_command_argv_internal): Don't create a temporary
1229 script/batch file if we are under -n. Call _setmode to switch the
1230 script file stream to text mode.
1232 2006-02-17 Paul D. Smith <psmith@gnu.org>
1234 * variable.c (merge_variable_set_lists): Don't try to merge the
1235 global_setlist. Not only is this useless, but it can lead to
1236 circularities in the linked list, if global_setlist->next in one
1237 list gets set to point to another list which also ends in
1238 global_setlist.
1239 Fixes Savannah bug #15757.
1241 2006-02-15 Paul D. Smith <psmith@gnu.org>
1243 Fix for Savannah bug #106.
1245 * expand.c (expanding_var): Keep track of which variable we're
1246 expanding. If no variable is being expanded, it's the same as
1247 reading_file.
1248 * make.h (expanding_var): Declare it.
1249 * expand.c (recursively_expand_for_file): Set expanding_var to the
1250 current variable we're expanding, unless there's no file info in
1251 it (could happen if it comes from the command line or a default
1252 variable). Restore it before we exit.
1253 * expand.c (variable_expand_string): Use the expanding_var file
1254 info instead of the reading_file info.
1255 * function.c (check_numeric): Ditto.
1256 (func_word): Ditto.
1257 (func_wordlist): Ditto.
1258 (func_error): Ditto.
1259 (expand_builtin_function): Ditto.
1260 (handle_function): Ditto.
1262 2006-02-14 Paul D. Smith <psmith@gnu.org>
1264 * read.c (eval): Even if the included filenames expands to the
1265 empty string we still need to free the allocated buffer.
1267 * implicit.c (pattern_search): If we allocated a variable set for
1268 an impossible file, free it.
1269 * variable.c (free_variable_set): New function.
1270 * variable.h: Declare it.
1272 * read.c (read_all_makefiles): Makefile names are kept in the
1273 strcache, so there's never any need to alloc/free them.
1274 (eval): Ditto.
1276 * main.c (main): Add "archives" to the .FEATURES variable if
1277 archive support is enabled.
1278 * doc/make.texi (Special Variables): Document it.
1280 2006-02-13 Paul D. Smith <psmith@gnu.org>
1282 * implicit.c (pattern_search): Add checking for DOS pathnames to
1283 the pattern rule target LASTSLASH manipulation.
1284 Fixes Savannah bug #11183.
1286 2006-02-11 Paul D. Smith <psmith@gnu.org>
1288 * (ALL FILES): Updated copyright and license notices.
1290 2006-02-10 Paul D. Smith <psmith@gnu.org>
1292 A new internal capability: the string cache is a read-only cache
1293 of strings, with a hash table interface for fast lookup. Nothing
1294 in the cache will ever be freed, so there's no need for reference
1295 counting, etc. This is the beginning of a full solution for
1296 Savannah bug #15182, but for now we only store makefile names here.
1298 * strcache.c: New file. Implement a read-only string cache.
1299 * make.h: Add prototypes for new functions.
1300 * main.c (initialize_global_hash_tables): Initialize the string cache.
1301 (print_data_base): Print string cache stats.
1302 * read.c (eval_makefile): Use the string cache to store makefile
1303 names. Rewrite the string allocation to be sure we free everything.
1305 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1307 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1308 directory time stamp didn't change, except on FAT filesystems.
1309 Suggested by J. David Bryan <jdbryan@acm.org>.
1311 2006-02-09 Paul D. Smith <psmith@gnu.org>
1313 * function.c (func_or): Implement a short-circuiting OR function.
1314 (func_and): Implement a short-circuiting AND function.
1315 (function_table_init): Update the table with the new functions.
1316 * doc/make.texi (Conditional Functions): Changed the "if" section
1317 to one on general conditional functions. Added documentation for
1318 $(and ...) and $(or ...) functions.
1319 * NEWS: Note new $(and ...) and $(or ...) functions.
1321 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1323 * job.h (struct child): Add the dontcare bitfield.
1324 * job.c (new_job): Cache dontcare flag.
1325 * job.c (reap_children): Use cached dontcare flag instead of the
1326 one in struct file. Fixes Savannah bug #15641.
1328 2006-02-06 Paul D. Smith <psmith@gnu.org>
1330 * vpath.c (selective_vpath_search): If the file we find has a
1331 timestamp from -o or -W, use that instead of the real time.
1332 * remake.c (f_mtime): If the mtime is a special token from -o or
1333 -W, don't overwrite it with the real mtime.
1334 Fixes Savannah bug #15341.
1336 Updates from Markus Mauhart <qwe123@chello.at>:
1338 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1339 (process_signal, process_last_err, process_exit_code): Manage
1340 invalid handle values.
1341 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1342 manage invalid handles; remove them.
1343 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1344 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1345 * README.cvs: Updates for building from CVS.
1347 2006-02-05 Paul D. Smith <psmith@gnu.org>
1349 * file.c (enter_file): Keep track of the last double_colon entry,
1350 to avoid walking the list every time we want to add a new one.
1351 Fixes Savannah bug #15533.
1352 * filedef.h (struct file): Add a new LAST pointer.
1354 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1355 the comparison. For 64-bits systems the result of the subtraction
1356 might not fit into an int. Use comparison instead.
1357 Fixes Savannah bug #15534.
1359 * doc/make.texi: Update the chapter on writing commands to reflect
1360 the changes made in 3.81 for backslash/newline and SHELL handling.
1362 2006-02-01 Paul D. Smith <psmith@gnu.org>
1364 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1365 variable st is not used when it's not initialized.
1366 Patch from Eli Zaretskii <eliz@gnu.org>.
1368 2006-01-31 Paul D. Smith <psmith@gnu.org>

1374 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
1375 J. Grant <jg@jguk.org>.
1377 * main.c: Update the copyright year in the version output.
1378 * prepare_w32.bat: Remove this file from the distribution.
1380 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1382 * remake.c (update_goal_chain): Set g->changed instead of
1383 incrementing it, as it is only 8-bit wide, and could overflow if
1384 many commands got started in update_file.
1386 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1388 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1389 MAXIMUM_WAIT_OBJECTS.
1390 (process_wait_for_any_private): Change dimension of handles[]
1391 array to MAXIMUM_WAIT_OBJECTS.
1392 (process_used_slots): New function.
1393 (process_register): Don't register more processes than the
1394 available number of slots.
1395 (process_easy): Don't start new processes if all slots are used up.
1397 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1398 are already more children than sub_proc.c can handle, behave as if
1399 the load were too high.
1400 (start_job_command): Fix a typo in error message when process_easy
1401 fails.
1403 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1405 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1406 the shell is not sh.exe.
1408 * job.c (create_batch_file): Renamed from create_batch_filename;
1409 all callers changed. Don't close the temporary file; return its
1410 file descriptor instead. New arg FD allows to return the file
1411 descriptor.
1412 (construct_command_argv_internal): Use _fdopen instead of fopen to
1413 open the batch file.
1415 2006-01-04 Paul D. Smith <psmith@gnu.org>
1417 * readme.vms: Updates for case-insensitive VMS file systems from

1430 doesn't exist.
1432 * read.c (eval): Be sure to strip off trailing whitespace from the

1434 struct dep when creating a new one.
1436 2005-12-28 Paul D. Smith <psmith@gnu.org>
1438 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1439 disable warnings for MSC.
1440 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1442 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1444 * doc/make.texi (Execution): Add a footnote about changes in
1445 handling of backslash-newline sequences. Mention the differences
1446 on MS-DOS and MS-Windows.
1448 * NEWS: More details about building the MinGW port and a pointer
1449 to README.W32. Fix the section name that describes the new
1450 backward-incompatible processing of backslash-newline sequences.
1451 The special processing of SHELL set to "cmd" is only relevant to
1452 MS-Windows, not MS-DOS.
1454 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1456 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1457 to DWORD, to avoid compiler warnings.
1458 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1459 use %ld in format, to avoid compiler warnings.

1462 (Appending): Fix cross-reference to Setting.
1463 (Special Variables, Secondary Expansion, File Name Functions)

1465 periods after a sentence.
1466 (Execution): Add @: after "e.g.".
1467 (Environment): Fix punctuation.
1468 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1469 (Shell Function, Target-specific): Add @: after "vs."
1471 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1473 * read.c (record_target_var): Initialize variable's export field
1474 with v_default instead of leaving it "initialized" by whatever
1475 garbage happened to be on the heap.
1477 2005-12-12 Paul D. Smith <psmith@gnu.org>
1479 * make.1: Fix some display errors and document all existing options.
1480 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1482 2005-12-11 Paul D. Smith <psmith@gnu.org>
1484 * implicit.c (pattern_search): If 2nd expansion is not set for
1485 this implicit rule, replace the pattern with the stem directly,
1486 and don't re-expand the variable list. Along with the other
1487 .SECONDEXPANSION changes below, fixes bug #13781.
1489 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1491 * implicit.c (pattern_search): Mark other files that this rule
1492 builds as targets so that they are not treated as intermediates
1493 by the pattern rule search algorithm. Fixes bug #13022.
1495 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1497 * remake.c (notice_finished_file): Propagate the change of
1498 modification time to all the double-colon entries only if
1499 it is the last one to be updated. Fixes bug #14334.
1501 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1503 * function.c (func_flavor): Implement the flavor function which
1504 returns the flavor of a variable.
1505 * doc/make.texi (Functions for Transforming Text): Document it.
1506 * NEWS: Add it to the list of new functions.
1508 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1510 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1511 variable.
1512 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1513 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1515 2005-10-26 Paul Smith <psmith@gnu.org>
1517 * read.c (record_files): Don't set deps flags if there are no deps.
1518 * maintMakefile: We only need to build the templates when we are
1519 creating a distribution, so don't do it for "all".
1521 2005-10-24 Paul D. Smith <psmith@gnu.org>

1530 prerequisite list was found in a static pattern rule.
1531 (free_dep_chain): Declare a prototype.
1532 * file.c (parse_prereqs): New function: break out some complexity
1533 from expand_deps().
1534 (expand_deps): If we aren't doing second expansion, replace % with
1535 the stem for static pattern rules. Call the new function.
1536 * filedef.h (parse_prereqs): Declare a prototype.
1537 * implicit.c (pattern_search): Initialize the new staticpattern
1538 field.
1539 * main.c (second_expansion): Declare a global variable to remember
1540 if the special target has been seen. Initialize the new
1541 staticpattern field for prerequisites.
1542 * make.h: Extern for second_expansion.
1543 * misc.c (free_dep_chain): New function: frees a struct dep list.
1544 * read.c (read_all_makefiles): Initialize the staticpattern field.
1545 (eval_makefile): Ditto.
1546 (record_files): Check for the .SECONDEXPANSION target and set
1547 second_expansion global if it's found.
1548 Use the new free_dep_chain() instead of doing it by hand.
1549 Set the staticpattern field for prereqs of static pattern targets.
1551 2005-10-16 Paul D. Smith <psmith@gnu.org>
1553 * main.c (main): Set CURDIR to be a file variable instead of a
1554 default, so that values of CURDIR inherited from the environment
1555 won't override the make value.
1557 2005-09-26 Paul D. Smith <psmith@gnu.org>
1559 * job.c (construct_command_argv_internal): If the line is empty
1560 remember to free the temporary argv strings.
1561 Fixes bug # 14527.
1563 2005-09-16 Paul D. Smith <psmith@gnu.org>
1565 * job.c (start_job_command): The noerror flag is a boolean (single
1566 bit); set it appropriately.

1571 * function.c (func_error): On Windows, output from $(info ...)
1572 seems to come in the wrong order. Try to force it with fflush().
1574 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1576 * read.c (record_files): Move code that sets stem for static
1577 pattern rules out of the if (!two_colon) condition so it is
1578 also executed for two-colon rules. Fixes Savannah bug #13881.
1580 2005-08-08 Paul D. Smith <psmith@gnu.org>
1582 * make.h: Don't test that __STDC__ is non-0. Some compilers
1583 (Windows for example) set it to 0 to denote "ISO C + extensions".
1584 Fixes bug # 13594.
1586 2005-08-07 Paul D. Smith <psmith@gnu.org>
1588 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1589 conditional (slightly different version of a fix from Eli).
1591 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1592 If make is running in parallel without -k and two jobs die in a
1593 row, but not too close to each other, then make will quit without
1594 waiting for the rest of the jobs to die.
1596 * main.c (die): Don't reset err before calling reap_children() the
1597 second time: we still want it to be in the error condition.
1598 * job.c (reap_children): Use a static variable, rather than err,
1599 to control whether or not the error message should be printed.
1601 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1603 * w32/subproc/sub_proc.c: Include signal.h.
1604 (process_pipe_io, process_file_io): Pass a pointer to a local
1605 DWORD variable to GetExitCodeProcess. If the exit code is
1606 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1608 * job.c [WINDOWS32]: Include windows.h.
1609 (main_thread) [WINDOWS32]: New global variable.
1610 (reap_children) [WINDOWS32]: Get the handle for the main thread
1611 and store it in main_thread.
1613 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1614 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1615 doing anything else. When we are done, close the main thread
1616 handle and exit with status 130.
1618 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1620 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1621 pointer to fprintf.
1623 * main.c (find_and_set_default_shell): If found a DOSish shell,
1624 set sh_found and the value of default_shell, and report the
1625 findings in debug mode.
1627 * job.c (construct_command_argv_internal): Check unixy_shell, not
1628 no_default_sh_exe, to decide whether to use Unixy or DOSish
1629 builtin commands.
1631 * README.W32: Update with info about the MinGW build.
1633 * build_w32.bat: Support MinGW.
1635 * w32/subproc/build.bat: Likewise.
1637 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1638 printing DWORD args.
1640 * function.c (windows32_openpipe): Fix format strings for printing
1641 DWORD args.
1643 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1644 'reap_mode'.
1645 (start_job_command): Fix format string for printing the result of
1646 process_easy.
1647 (start_job_command) [WINDOWS32]: Do not define.
1648 (exec_command): Fix format string for printing HANDLE args.
1650 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1651 to avoid compiler warnings.
1652 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1653 (Note: some of these fixes were submitted independently by J. Grant)
1655 2005-07-30 J. Grant <jg@jguk.org>
1657 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1658 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1659 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1661 2005-07-15 Paul Smith <psmith@gnu.org>
1663 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1664 we don't have a POSIX shell, then revert to the old
1665 backslash-newline behavior (where they are stripped).
1666 Fixes bug #13665.
1668 2005-07-08 Paul D. Smith <psmith@gnu.org>
1670 * config.h.W32.template: Reorder to match the standard config.h,
1671 for easier comparisons.
1672 From J. Grant <jg@jguk.org>
1674 * maintMakefile: Remove .dep_segment before overwriting it, in
1675 case it's not writable or noclobber is set.
1676 * expand.c (variable_expand_string): Cast result of pointer
1677 arithmetic to avoid a warning.
1678 * main.c (switches): Add full-fledged final initializer.
1680 2005-07-06 Paul D. Smith <psmith@gnu.org>
1682 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1683 * signame.c (strsignal): If we found _sys_siglist[] or
1684 __sys_siglist[] use those instead of sys_siglist[].
1685 From Albert Chin <china@thewrittenword.com>
1687 2005-07-04 Paul D. Smith <psmith@gnu.org>
1689 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1690 globfree(); set up to use the GNU versions.
1691 From Martin Zinser <zinser@zinser.no-ip.info>
1693 2005-07-03 Paul D. Smith <psmith@gnu.org>
1695 From J. Grant <jg@jguk.org>:
1697 * README.W32.template: Update the Windows and tested MSVC versions.
1698 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1699 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1700 * build_w32.bat: Ditto.
1701 * w32/subproc/build.bat: Ditto.
1703 2005-06-28 Paul D. Smith <psmith@gnu.org>
1705 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1706 declaration was checked but not present.
1708 2005-06-27 Paul D. Smith <psmith@gnu.org>
1710 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1711 to unsigned long. Fixes Savannah bug #13550.
1713 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1714 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1715 Fixes Savannah bug #13551.
1717 2005-06-26 Paul D. Smith <psmith@gnu.org>
1719 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1720 it if ANSI_STRING is not set.
1722 2005-06-25 Paul D. Smith <psmith@gnu.org>
1724 * read.c (eval): If no filenames are passed to any of the
1725 "include" variants, don't print an error.
1726 * doc/make.texi (Include): Document this.
1727 Fixes Savannah bug #1761.
1729 * job.c (construct_command_argv_internal): Sanitize handling of
1730 backslash/newline pairs according to POSIX: that is, keep the
1731 backslash-newline in the command script, but remove a following
1732 TAB character, if present. In the fast path, make sure that the
1733 behavior matches what the shell would do both inside and outside
1734 of quotes. In the slow path, quote the backslash and put a
1735 literal newline in the string.
1736 Fixes Savannah bug #1332.
1737 * doc/make.texi (Execution): Document the new behavior and give
1738 some examples.
1739 * NEWS: Make a note of the new behavior.
1741 * make.h [WINDOWS32]: #include <direct.h>.
1742 Fixes Savannah bug #13478.
1744 * remake.c (name_mtime): If the stat() of a file fails and the -L
1745 option was given and the file is a symlink, take the best mtime of
1746 the symlink we can get as the mtime of the file and don't fail.
1747 Fixes Savannah bug #13280.
1749 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1750 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1751 inside a variable reference. Make this function static as it's
1752 only used here.
1753 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1754 parsing an unexpanded line looking for semicolons.
1755 Fixes Savannah bug #1454.
1756 * misc.c (remove_comments): Move this to read.c and make it static
1757 as it's only used there. Call find_char_unquote() with new arg.
1758 * make.h: Remove prototypes for find_char_unquote() and
1759 remove_comments() since they're static now.
1761 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1762 its export flag and obtain its value. When we need to re-exec,
1763 increment the value and add it into the environment.
1764 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1765 * NEWS: Mention MAKE_RESTARTS.
1766 * main.c (always_make_set): New variable. Change the -B option to
1767 set this one instead.
1768 (main): When checking makefiles, only set always_make_flag if
1769 always_make_set is set AND the restarts flag is 0. When building
1770 normal targets, set it IFF always_make_set is set.
1771 (main): Avoid infinite recursion with -W, too: only set what-if
1772 files to NEW before we check makefiles if we've never restarted
1773 before. If we have restarted, set what-if files to NEW _after_ we
1774 check makefiles.
1775 Fixes Savannah bug #7566:
1777 2005-06-17 Paul D. Smith <psmith@gnu.org>
1779 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1780 in the prerequisites list.
1782 2005-06-12 Paul D. Smith <psmith@gnu.org>
1784 Fix Savannah bug # 1328.
1786 * configure.in: Check for atexit().
1787 * misc.c (close_stdout): Test stdout to see if writes to it have
1788 failed. If so, be sure to exit with a non-0 error code. Based on
1789 code found in gnulib.
1790 * make.h: Prototype.
1791 * main.c (main): Install close_stdout() with atexit().
1793 2005-06-10 Paul D. Smith <psmith@gnu.org>
1795 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1797 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1798 headers; make vmsWaitForChildren() static; extern vmsify().
1799 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1800 Don't create child_execute_job() here (it's in vmsjobs.c).
1801 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1803 2005-06-09 Paul D. Smith <psmith@gnu.org>
1805 * variable.c (push_new_variable_scope): File variables point
1806 directly to the global_setlist variable. So, inserting a new
1807 scope in front of that has no effect on those variables: they
1808 don't go through current_variable_set_list. If we're pushing a
1809 scope and the current scope is global, push it "the other way" so
1810 that the new setlist is in the global_setlist variable, and
1811 next points to a new setlist with the global variable set.
1812 (pop_variable_scope): Properly undo a push with the new
1813 semantics.
1814 Fixes Savannah bug #11913.
1816 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1818 * job.c (reap_children): Don't die of the command failed but
1819 the dontcare flag is set. Fixes Savannah bug #13216.
1821 * implicit.c (pattern_search): When creating a target from
1822 an implicit rule match, lookup pattern target and set precious
1823 flag in a newly created target. Fixes Savannah bug #13218.
1825 2005-05-13 Paul D. Smith <psmith@gnu.org>
1827 Implement "if... else if... endif" syntax.
1829 * read.c (eval): Push all checks for conditional words ("ifeq",
1830 "else", etc.) down into the conditional_line() function.
1831 (conditional_line): Rework to allow "else if..." clause. New
1832 return value -2 for lines which are not conditionals. The
1833 ignoring flag can now also be 2, which means "already parsed a
1834 true branch". If that value is seen no other branch of this
1835 conditional can be considered true. In the else parsing if there
1836 is extra text after the else, invoke conditional_line()
1837 recursively to see if it's another conditional. If not, it's an
1838 error. If so, raise the conditional value to this level instead
1839 of creating a new conditional nesting level. Special check for
1840 "else" and "endif", which aren't allowed on the "else" line.
1841 * doc/make.texi (Conditional Syntax): Document the new syntax.
1843 2005-05-09 Paul D. Smith <psmith@gnu.org>
1845 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1846 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1847 recurses to the w32 directory, even on non-Windows systems. Use
1848 the method suggested in the automake manual.
1849 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1850 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1852 2005-05-07 Paul D. Smith <psmith@gnu.org>
1854 * main.c (die): If we're dying with a fatal error (not that a
1855 command has failed), write back any leftover tokens before we go.
1857 * job.c (set_child_handler_action_flags): If there are jobs
1858 waiting for the load to go down, set an alarm to go off in 1
1859 second. This allows us to wake up from a potentially long-lasting
1860 read() and start a new job if the load has gone down. Turn it off
1861 after the read.
1862 (job_noop): Dummy signal handler function.
1863 (new_job): Invoke it with the new semantics.
1865 * docs/make.texi: Document secondary expansion. Various cleanups
1866 and random work.
1868 2005-05-03 Paul D. Smith <psmith@gnu.org>
1870 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1871 the targets which are to ultimately be made are called "goals";
1872 see the GNU make manual. Also, MAKECMDGOALS, etc.
1874 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1875 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1876 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1878 2005-05-02 Paul D. Smith <psmith@gnu.org>
1880 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1881 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1882 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1883 functions to vmsjobs.c. #include it into jobs.c.
1885 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1886 jobserver tokens. I found that this happens when an exported
1887 recursive variable contains a $(shell ...) function reference: in
1888 this situation we could "forget" to write back a token.
1890 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1891 we have. It's not reliable to depend on the number of children in
1892 our linked list so keep a separate count.
1893 (new_job): Check jobserver_tokens rather than children &&
1894 waiting_jobs. Increment jobserver_tokens when we get one.
1895 (free_child): If jobserver_tokens is 0, internal error. If it's
1896 >1, write a token back to the jobserver pipe (we don't write a
1897 token for the "free" job). Decrement jobserver_tokens.
1899 * main.c: Add variable master_job_slots.
1900 (main): Set it to hold the number of jobs requested if we're the
1901 master process, when using the jobserver.
1902 (die): Sanity checks: first test jobserver_tokens to make sure
1903 this process isn't holding any tokens we didn't write back.
1904 Second, if master_job_slots is set count the tokens left in the
1905 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1907 2005-04-24 Paul D. Smith <psmith@gnu.org>
1909 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1910 with -l# can lose jobserver tokens, because waiting jobs are not
1911 consulted properly when checking for the "free" token.
1913 * job.c (free_child): Count waiting_jobs as having tokens.
1914 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1915 handle jobs waiting for the load to drop.
1917 2005-04-23 Paul D. Smith <psmith@gnu.org>
1919 * main.c (main): Be careful to not core if a variable setting in
1920 the environment doesn't contain an '='. This is illegal but can
1921 happen in broken setups.
1922 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1924 2005-04-12 Paul D. Smith <psmith@gnu.org>
1926 The second expansion feature causes significant slowdown. Timing
1927 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1928 read the makefile before the feature, to 11+s to do the same
1929 operations after the feature. Additionally, memory usage
1930 increased drastically. To fix this I added some intelligence that
1931 avoids the overhead of the second expansion unless it's required.
1933 * dep.h: Add a new boolean field, need_2nd_expansion.
1935 * read.c (eval): When creating the struct dep for the target,
1936 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1937 (record_files): If there's a "%" in a static pattern rule, it gets
1938 converted to "$*" so set need_2nd_expansion to 1.
1940 * file.c (expand_deps): Rework to be more efficient. Only perform
1941 initialize_file_variables(), set_file_variables(), and
1942 variable_expand_for_file() if the need_2nd_expansion is set.
1944 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1945 (pattern_search): Ditto.
1946 * main.c (handle_non_switch_argument): Ditto.
1947 (main): Ditto.
1948 * read.c (read_all_makefiles): Ditto.
1949 (eval_makefile): Ditto.
1951 2005-04-07 Paul D. Smith <psmith@gnu.org>
1953 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1954 * variable.c (sync_Path_environment): Ditto.
1955 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1957 * main.c (main): Define the .FEATURES variable.
1958 * NEWS: Announce .FEATURES.
1959 * doc/make.texi (Special Variables): Document .FEATURES.
1961 * remake.c (check_dep): If a file is .PHONY, update it even if
1962 it's marked intermediate. Fixes Savannah bug #12331.
1964 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1966 * file.c (expand_deps): Factor out the second expansion and
1967 prerequisite line parsing logic from snap_deps().
1969 * file.c (snap_deps): Use expand_deps(). Expand and parse
1970 prerequisites of the .SUFFIXES special target first. Fixes
1971 Savannah bug #12320.
1973 2005-03-13 Paul D. Smith <psmith@gnu.org>
1975 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1976 Zaretskii.
1978 2005-03-11 Paul D. Smith <psmith@gnu.org>
1980 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1981 available, not undefined (from Earnie Boyd).
1983 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1985 * implicit.c (pattern_search): Mark an intermediate target as
1986 precious if it happened to be a prerequisite of some (other)
1987 target. Fixes Savannah bug #12267.
1989 2005-03-09 Paul D. Smith <psmith@gnu.org>
1991 * read.c (eval_makefile): Add alloca(0).
1992 (eval_buffer): Ditto.
1994 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1996 * main.c (main): Use o_file instead of o_default when defining
1997 the .DEFAULT_TARGET special variable.
1998 * read.c (eval): Use define_variable_global() instead of
1999 define_variable() when setting new value for the .DEFAULT_TARGET
2000 special variable. Fixes Savannah bug #12266.
2002 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2004 * imlicit.c (pattern_search): Mark files for which an implicit
2005 rule has been found as targets. Fixes Savannah bug #12202.
2007 2005-03-04 Paul D. Smith <psmith@gnu.org>
2009 * AUTHORS: Update.
2010 * doc/make.texi (Automatic Variables): Document $|.
2012 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2014 * read.c (record_files): Instead of substituting % with
2015 actual stem value in dependency list replace it with $*.
2016 This fixes stem triple expansion bug.
2018 * implicit.c (pattern_search): Copy stem to a separate
2019 buffer and make it a properly terminated string. Assign
2020 this buffer instead of STEM (which is not terminated) to
2021 f->stem. Instead of substituting % with actual stem value
2022 in dependency list replace it with $*. This fixes stem
2023 triple expansion bug.
2025 2005-03-01 Paul D. Smith <psmith@gnu.org>
2027 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2028 on Windows, as it takes a handle not a pid. Just exit.
2029 Fix from patch #3679, provided by Alessandro Vesely.
2031 * configure.in: Update check for sys_siglist[] from autoconf manual.
2032 * signame.c (strsignal): Update to use the new autoconf macro.
2034 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2036 * read.c (record_files): Add a check for the list of prerequisites
2037 of a static pattern rule being empty. Fixes Savannah bug #12180.
2039 2005-02-28 Paul D. Smith <psmith@gnu.org>
2041 * doc/make.texi (Text Functions): Update docs to allow the end
2042 ordinal for $(wordlist ...) to be 0.
2043 * function.c (func_wordlist): Fail if the start ordinal for
2044 $(wordlist ...) is <1. Matches documentation.
2045 Resolves Savannah support request #103195.
2047 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2048 previously we were stopping when !-q, exactly the opposite. This
2049 has been wrong since version 1.34, in 1994!
2050 (update_file): If we got an error don't break out to run more
2051 double-colon rules: just return immediately.
2052 Fixes Savannah bug #7144.
2054 2005-02-27 Paul D. Smith <psmith@gnu.org>
2056 * misc.c (end_of_token): Make argument const.
2057 * make.h: Update prototype.
2059 * function.c (abspath, func_realpath, func_abspath): Use
2060 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2061 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2062 * read.c (record_files): Ditto.
2063 * variable.c (do_variable_definition): Ditto.
2065 * function.c (func_error): Create a new function $(info ...) that
2066 simply prints the message to stdout with no extras.
2067 (function_table_init): Add new function to the table.
2068 * NEWS: Add $(info ...) reference.
2069 * doc/make.texi (Make Control Functions): Document it.
2071 New feature: if the system supports symbolic links, and the user
2072 provides the -L/--check-symlink-time flag, then use the latest
2073 mtime between the symlink(s) and the target file.
2075 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2076 readlink(). If both are available, define MAKE_SYMLINKS.
2077 * main.c: New variable: check_symlink_flag.
2078 (usage): Add a line for -L/--check-symlink-times to the help string.
2079 (switches): Add -L/--check-symlink-times command line argument.
2080 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2081 print a warning and disable it again.
2082 * make.h: Declare check_symlink_flag.
2083 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2084 if the file is a symlink then check each link in the chain and
2085 choose the NEWEST mtime we find as the mtime for the file. The
2086 newest mtime might be the file itself!
2087 * NEWS: Add information about this new feature.
2088 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2090 Avoid core dumps described in Savannah bug # 12124:
2092 * file.c: New variable snapped_deps remember whether we've run
2093 snap_deps().
2094 (snap_deps): Set it.
2095 * filedef.h: Extern it.
2096 * read.c (record_files): Check snapped_deps; if it's set then
2097 we're trying to eval a new target/prerequisite relationship from
2098 within a command script, which we don't support. Fatal.
2100 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2102 Implementation of the .DEFAULT_TARGET special variable.
2104 * read.c (eval): If necessary, update default_target_name when
2105 reading rules.
2106 * read.c (record_files): Update default_target_file if
2107 default_target_name has changed.
2108 * main.c (default_target_name): Define.
2109 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2110 default_target_name is set use default_target_file as a root
2111 target to make.
2112 * filedef.h (default_target_name): Declare.
2113 * dep.h (free_dep_chain):
2114 * misc.c (free_dep_chain): Change to operate on struct nameseq
2115 and change name to free_ns_chain.
2116 * file.c (snap_deps): Update to use free_ns_chain.
2118 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2120 Implementation of the second expansion in explicit rules,
2121 static pattern rules and implicit rules.
2123 * read.c (eval): Refrain from chopping up rule's dependencies.
2124 Store them in a struct dep as a single dependency line. Remove
2125 the code that implements SySV-style automatic variables.
2127 * read.c (record_files): Adjust the code that handles static
2128 pattern rules to expand all percents instead of only the first
2129 one. Reverse the order in which dependencies are stored so that
2130 when the second expansion reverses them again they appear in
2131 the makefile order (with some exceptions, see comments in
2132 the code). Remove the code that implements SySV-style automatic
2133 variables.
2135 * file.c (snap_deps): Implement the second expansion and chopping
2136 of dependency lines for explicit rules.
2138 * implicit.c (struct idep): Define an auxiliary data type to hold
2139 implicit rule's dependencies after stem substitution and
2140 expansion.
2142 * implicit.c (free_idep_chain): Implement.
2144 * implicit.c (get_next_word): Implement helper function for
2145 parsing implicit rule's dependency lines into words taking
2146 into account variable expansion requests. Used in the stem
2147 splitting code.
2149 * implicit.c (pattern_search): Implement the second expansion
2150 for implicit rules. Also fixes bug #12091.
2152 * commands.h (set_file_variables): Declare.
2153 * commands.c (set_file_variables): Remove static specifier.
2155 * dep.h (free_dep_chain): Declare.
2156 * misc.c (free_dep_chain): Implement.
2158 * variable.h (variable_expand_for_file): Declare.
2159 * expand.c (variable_expand_for_file): Remove static specifier.
2161 * make.h (strip_whitespace): Declare.
2162 * function.c (strip_whitespace): Remove static specifier.
2164 2005-02-26 Paul D. Smith <psmith@gnu.org>
2166 * main.c (main): Check for ferror() when reading makefiles from stdin.
2167 Apparently some shells in Windows don't close pipes properly and
2168 require this check.
2170 2005-02-24 Jonathan Grant <jg@jguk.org>
2172 * configure.in: Add MinGW configuration options, and extra w32 code
2173 directory.
2174 * Makefile.am: Add MinGW configuration options, and extra w32 code
2175 directory.
2176 * main.c: Determine correct program string (after last \ without .exe).
2177 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2178 type fix x2
2179 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2180 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2181 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2182 environment support.
2184 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2186 * function.c (func_shell): When initializing error_prefix, check
2187 that reading file name is not null. This fixes long-standing
2188 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2190 2005-02-09 Paul D. Smith <psmith@gnu.org>
2192 * maintMakefile: Update the CVS download URL to simplify them.
2193 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2194 downloading the .texi files from Savannah now.
2196 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2198 * main.c (handle_non_switch_argument): Only add variables to
2199 command_variables if they're not already there: duplicate settings
2200 waste space and can be confusing to read.
2202 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2203 this header is never included by non-WINDOWS32 code, and it
2204 requires <config.h> to define which isn't always included first.
2206 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2207 testing MINGW32 versions.
2209 * main.c (log_working_directory): flush stdout to be sure the WD
2210 change is printed before any stderr messages show up.
2212 2005-02-01 Paul D. Smith <psmith@gnu.org>
2214 * maintMakefile (po_repo): Update the GNU translation site URL.
2216 2004-12-01 Paul D. Smith <psmith@gnu.org>
2218 * main.c (main): Change char* env_shell to struct variable shell_var.
2219 * variable.c (target_environment): Use new shell_var.
2221 2004-11-30 Paul D. Smith <psmith@gnu.org>
2223 * configure.in: The old way we avoided creating build.sh from
2224 build.sh.in before build.sh.in exists doesn't work anymore; we
2225 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2226 the help!). This also keeps automake from complaining.
2227 * Makefile.am (README): Add a dummy target so automake won't
2228 complain that this file doesn't exist when we checkout from CVS.
2229 * maintMakefile (.dep_segment): Rewrite this rule since newer
2230 versions of automake don't provide DEP_FILES.
2232 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2234 Implementation of `realpath' and `abspath' built-in functions.
2236 * configure.in: Check for realpath.
2237 * function.c (abspath): Return an absolute file name that does
2238 not contain any `.' or `..' components, nor repeated `/'.
2239 * function.c (func_abspath): For each name call abspath.
2240 * function.c (func_realpath): For each name call realpath
2241 from libc or delegate to abspath if realpath is not available.
2242 * doc/make.texi (Functions for File Names): Document new functions.
2243 * doc/make.texi (Quick Reference): Ditto.
2245 2004-11-28 Paul D. Smith <psmith@gnu.org>
2247 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2248 arguments. Fixes bug #10252.
2250 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2252 * main.c (main): Set SHELL to v_noexport by default. Remember the
2253 original environment setting of SHELL in the env_shell variable.
2254 * main.h: Export new env_shell variable.
2255 * variable.c (target_environment): If we find a v_noexport
2256 variable for SHELL, add a SHELL variable with the env_shell value.
2257 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2258 * doc/make.texi (Variables/Recursion): Ditto.
2260 2004-11-28 Paul D. Smith <psmith@gnu.org>
2262 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2263 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2264 Patch by Alessandro Vesely.
2266 2004-11-12 Paul D. Smith <psmith@gnu.org>
2268 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2269 the command line if it's inside a string.
2270 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2272 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2274 * function.c (func_lastword): New function: return last word
2275 from the list of words.
2276 * doc/make.texi: Document $(lastword ). Fix broken links in
2277 Quick Reference section.
2279 2004-10-06 Paul D. Smith <psmith@gnu.org>
2281 Apply patch from Alessandro Vesely, provided with bug # 9748.
2282 Fix use of tmpnam() to work with Borland C.
2284 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2285 construction of a temporary filename, and call new function
2286 create_batch_filename().
2287 (create_batch_filename) [WINDOWS32]: New function to create a
2288 temporary filename.
2290 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2292 * read.c (record_target_var): Expand simple pattern-specific
2293 variable.
2294 * variable.c (initialize_file_variables): Do not expand simple
2295 pattern-specific variable.
2297 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2299 * remake.c (update_file_1): When rebuilding makefiles inherit
2300 dontcare flag from a target that triggered update.
2302 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2304 * variable.c (initialize_file_variables): Mark pattern-specific
2305 variable as a per-target and copy export status.
2307 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2309 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2311 * implicit.c (pattern_search): When considering an implicit rule's
2312 prerequisite check that it is actually a target rather then
2313 just an entry in the file hashtable.
2315 2004-09-21 Paul D. Smith <psmith@gnu.org>
2317 * read.c (readstring): Fix some logic errors in backslash handling.
2318 (eval): Remove some unnecessary processing in buffer handling.
2319 (record_target_var): Assert that parse_variable_definition() succeeded.
2320 Reported by: Markus Mauhart <qwe123@chello.at>.
2322 * misc.c: Removed the sindex() function. All instances of this
2323 function were trivially replaceable by the standard strstr()
2324 function, and that function will always have better (or certainly
2325 no worse) performance than the very simple-minded algorithm
2326 sindex() used. This can matter with complex makefiles.
2327 * make.h: Remove the prototype for sindex().
2328 * function.c (subst_expand): Convert sindex() call to strstr().
2329 This means we no longer need to track the TLEN value so remove that.
2330 (func_findstring): Convert sindex() to strstr().
2331 * commands.c (chop_commands): Convert sindex() calls to strstr().
2332 Suggested by: Markus Mauhart <qwe123@chello.at>.
2334 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2335 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2336 If SHELL is set to CMD.EXE then assume it's batch-mode and
2337 non-unixy. I wrote the code differently from the patch, though,
2338 to make it safer. This also resolves bug #9174.
2340 2004-09-20 Paul D. Smith <psmith@gnu.org>
2342 * expand.c (variable_expand_string): Modify to invoke
2343 patsubst_expand() instead of subst_expand(); the latter didn't
2344 handle suffix patterns correctly.
2345 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2346 was used only from variable_expand_string() and is no longer used
2347 there.
2348 (func_subst): Ditto, on call to subst_expand().
2349 (patsubst_expand): Require the percent pointers to point to the
2350 character after the %, not to the % itself.
2351 * read.c (record_files): New call criteria for patsubst_expand().
2352 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2353 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2355 2004-09-19 Paul D. Smith <psmith@gnu.org>
2357 * function.c (subst_expand): Fix a check in by_word: look for a
2358 previous blank if we're beyond the beginning of the string, not
2359 the beginning of the word.
2360 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2362 2004-05-16 Paul D. Smith <psmith@gnu.org>
2364 * remake.c (update_goal_chain): Change the argument specifying
2365 whether we're rebuilding makefiles to be a global variable,
2366 REBUILDING_MAKEFILES.
2367 (complain): Extract the code that complains about no rules to make
2368 a target into a separate function.
2369 (update_file_1): If we tried to rebuild a file during the makefile
2370 rebuild phase and it was dontcare, then no message was printed.
2371 If we then try to build the same file during the normal build,
2372 print a message this time.
2373 (remake_file): Don't complain about un-remake-able files when
2374 we're rebuilding makefiles.
2376 2004-05-11 Paul D. Smith <psmith@gnu.org>
2378 * job.c (construct_command_argv_internal): OS/2 patches from
2379 Andreas Buening <andreas.buening@nexgo.de>.
2381 2004-05-10 Paul D. Smith <psmith@gnu.org>
2383 * remake.c (update_file): Don't walk the double-colon chain unless
2384 this is a double-colon rule. Fix suggested by Boris Kolpackov
2385 <boris@kolpackov.net>.
2387 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2388 * readme.vms: New section describing OpenVMS support and issues.
2389 * default.c (default_variables): Add support for IA64.
2390 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2391 without some privilege aborts make with the error
2392 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2393 pressing Ctrl+Y and the input device is no terminal. The change
2394 catches this error and just continues.
2396 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2398 2004-04-25 Paul D. Smith <psmith@gnu.org>
2400 * commands.c (set_file_variables): Set $< properly in the face of
2401 order-only prerequisites.
2402 Patch from Boris Kolpackov <boris@kolpackov.net>
2404 2004-04-21 Bob Byrnes <byrnes@curl.com>
2406 * main.c (main): Notice failures to remake makefiles.
2408 2004-03-28 Paul D. Smith <psmith@gnu.org>
2410 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2412 * job.c: No default shell for RISC OS.
2413 (load_too_high): Hard-code the return to 1.
2414 (construct_command_argv_internal): No sh_chars or sh_cmds.
2415 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2417 2004-03-20 Paul D. Smith <psmith@gnu.org>
2419 * variable.c (do_variable_definition): Don't append from the
2420 global set if a previous non-appending target-specific variable
2421 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2422 (with fix).
2424 * expand.c (reference_variable): Don't give up on variables with
2425 no value that have the target-specific append flag set: they might
2426 have a value after all. Reported by Oliver Schmidt
2427 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2428 <nikulin@dx1cmd.inp.nsk.su>.
2430 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2431 refer to absolute pathnames in directories that don't exist: some
2432 portion of the makefile could create those directories before we
2433 match the pattern. Fixes bugs #775 and #108.
2435 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2437 * main.c (main): Free makefile_mtimes if we have any.
2438 * README.W32.template: Update documentation for the current status
2439 of the MS-Windows port.
2440 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2441 environment variable is sometimes already defined which causes the
2442 build to fail.
2443 * main.c (debug_signal_handler): Only define this function if
2444 SIGUSR1 is available.
2446 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2448 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2449 * README.OS2.template: Documentation updates.
2450 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2451 link line for safety.
2452 * maintMakefile (build.sh.in): Remove an extraneous ")".
2453 * job.c (child_execute_job): Close saved FDs.
2454 * job.c (exec_command) [OS/2]: exec_command(): If the command
2455 can't be exec'ed and if the shell is not Unix-sh, then try again
2456 with argv = { "cmd", "/c", ... }. Normally, this code is never
2457 reached for the cmd shell unless the command really doesn't exist.
2458 (construct_command_argv_internal) [OS/2]: The code for cmd
2459 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2460 The CMD builtin commands are case insensitive so use strcasecmp().
2462 2004-03-19 Paul D. Smith <psmith@gnu.org>
2464 * read.c (do_define): Re-order line counter increment so the count
2465 is accurate (we were losing one line per define). Reported by
2466 Dave Yost <Dave@Yost.com>.
2468 2004-03-06 Paul D. Smith <psmith@gnu.org>
2470 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2471 compiler.
2472 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2473 * misc.c (message,error,fatal): Ditto.
2474 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2475 * config.h.W32.template: Ditto.
2476 * config.h-vms.template: Ditto.
2477 * config.ami.template: Ditto.
2479 2004-03-04 Paul D. Smith <psmith@gnu.org>
2481 * README.template: Add a note about broken /bin/sh on SunOS
2482 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2484 * misc.c (message, error, fatal): Don't use "..." if we're using
2485 varargs. ansi2knr should handle this but it doesn't work: it
2486 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2487 done. On many systems (SunOS for example) va_dcl is a #define.
2488 So, force the use of the non-"..." version on pre-ANSI compilers.
2490 * maintMakefile (sign-dist): Create some rules to help automate
2491 the new GNU ftp upload method.
2493 2004-02-24 Paul D. Smith <psmith@gnu.org>
2495 * config.h.W32.template: Add HAVE_STDARG_H
2496 * config.h-vms.template: Ditto.
2497 * config.ami.template: Ditto.
2499 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2501 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2502 * build_w32.bat: Remove extra "+".
2504 2004-02-23 Paul D. Smith <psmith@gnu.org>
2506 * make.h: Create an UNUSED macro to mark unused parameters.
2507 * (many): Clean up warnings by applying UNUSED, fixing
2508 signed/unsigned incompatibilities, etc.
2510 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2511 autoconf warnings.
2512 * filedef.h: Name the command_state enumeration.
2513 * file.c (set_command_state): Use the enumeration in the function
2514 argument.
2516 * configure.in: Explicitly set SET_MAKE to empty, to disable
2517 MAKE=make even when no make already exists. Fix bug #3823.
2519 2004-02-22 Paul D. Smith <psmith@gnu.org>
2521 * maintMakefile: Perl script to clean up all non-CVS files. Use
2522 it on all the subdirectories for the cvs-clean target.
2524 * main.c (decode_switches): Require non-empty strings for all our
2525 string command-line options. Fixes Debian bug # 164165.
2527 * configure.in: Check for stdarg.h and varargs.h.
2528 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2529 for printing messages.
2530 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2531 (message): Ditto.
2532 (error): Ditto.
2533 (fatal): Ditto.
2535 A number of patches for OS/2 support from Andreas Buening
2536 <andreas.buening@nexgo.de>:
2538 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2539 disable the SIGCHLD handler.
2540 (reap_children) [OS/2]: Remove special handling of job_rfd.
2541 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2542 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2543 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2544 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2545 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2546 systems.
2548 2004-02-21 Paul D. Smith <psmith@gnu.org>
2550 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2551 <mail@kristov.de> reports that if process_begin() fails we don't
2552 handle the error condition correctly in all cases.
2553 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2554 to have a newline on the message.
2556 * job.c (construct_command_argv_internal): Add "test" to UNIX
2557 sh_cmds[]. Fixes Savannah bug # 7606.
2559 2004-02-04 Paul D. Smith <psmith@gnu.org>
2561 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2562 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2563 Hartmut Becker <Hartmut.Becker@hp.com>.
2565 2004-01-21 Paul D. Smith <psmith@gnu.org>
2567 * job.c (load_too_high): Implement an algorithm to control the
2568 "thundering herd" problem when using -l to control job creation
2569 via the load average. The system only recomputes the load once a
2570 second but we can start many jobs in a second. To solve this we
2571 keep track of the number of jobs started in the last second and
2572 apply a weight to try to guess what a correct load would be.
2573 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2574 Also fixes bug #4693.
2575 (reap_children): Decrease the job count for this second.
2576 (start_job_command): Increase the job count for this second.
2578 * read.c (conditional_line): Expand the text after ifn?def before
2579 checking to see if it's a single word. Fixes bug #7257.
2581 2004-01-09 Paul D. Smith <psmith@gnu.org>
2583 * file.c (print_file): Recurse to print all targets in
2584 double-colon rules. Fixes bug #4518, reported (with patch) by
2585 Andrew Chatham <chatham@google.com>.
2587 2004-01-07 Paul D. Smith <psmith@gnu.org>
2589 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2590 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2591 AC_FUNC_SETVBUF_REVERSED.
2593 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2594 (MAKE Variable): Fix Savannah bug #4898.
2596 * job.c (construct_command_argv_internal): Add "!" to the list of
2597 shell escape chars. POSIX sh allows it to appear before a
2598 command, to negate the exit code. Fixes bug #6404.
2600 * implicit.c (pattern_search): When matching an implicit rule,
2601 remember which dependencies have the ignore_mtime flag set.
2602 Original fix provided in Savannah patch #2349, by Benoit
2603 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2605 2003-11-22 Paul D. Smith <psmith@gnu.org>
2607 * README.W32.template (Outputs): Clarification on -j with
2608 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2609 <jg-make@jguk.org>.
2611 2003-11-02 Paul D. Smith <psmith@gnu.org>
2613 * function.c (func_if): Strip all the trailing whitespace from the
2614 condition, then don't expand it. Fixed bug # 5798.
2616 * expand.c (recursively_expand_for_file): If we're expanding a
2617 variable with no file context, then use the variable's context.
2618 Fixes bug # 6195.
2620 2003-10-21 Paul D. Smith <psmith@gnu.org>
2622 * main.c (log_working_directory): Add newlines to printf()s.
2624 * README.cvs: Add a note to ignore warnings during autoreconf.
2626 * maintMakefile (po_repo): Set a new URL for PO file updates.
2627 (get-config/config.guess get-config/config.sub): Get these files
2628 from the Savannah config project instead of ftp.gnu.org.
2630 2003-10-05 Paul Eggert <eggert@twinsun.com>
2632 * main.c (main): Avoid potential subscript error if environ has
2633 short strings.
2635 2003-08-22 Paul D. Smith <psmith@gnu.org>
2637 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2638 systems which don't yet implement the C89 standard :-/.
2640 2003-07-18 Paul D. Smith <psmith@gnu.org>
2642 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2643 [WINDOWS32]: Initialize hash.
2645 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2647 * dir.c (read_dirstream): Provide a workaround for broken versions of
2648 the MinGW dirent structure.
2650 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2652 * w32/include/dirent.h: Add __MINGW32__ filter.
2654 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2656 * make.h: Add global declaration of *make_host.
2657 * main.c (print_usage): Remove local declaration of *make_host.
2658 (print_version): Display "This program built for ..." after Copyright
2659 notice.
2661 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2663 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2664 execution of "makeinfo --html make.texi".
2666 2003-04-30 Paul D. Smith <psmith@gnu.org>
2668 * build.template: Make some changes to maybe allow this script to
2669 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2671 * README.OS2.template: New file for OS/2 support. Original
2672 contributed by Andreas Buening.
2673 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2674 DOS-style paths.
2676 2003-04-19 Paul D. Smith <psmith@gnu.org>
2678 Fix bug #1405: allow a target to match multiple pattern-specific
2679 variables.
2681 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2682 variable.c, where they've always belonged.
2683 * rule.h: Move the prototypes and struct pattern_var as well.
2684 * variable.c (initialize_file_variables): Invoke
2685 lookup_pattern_var() in a loop, until no more matches are found.
2686 If a match is found, create a new variable set for the target's
2687 pattern variables. Then merge the contents of each matching
2688 pattern variable set into the target's pattern variable set.
2689 (lookup_pattern_var): Change this function to be usable
2690 in a loop. It takes a starting position: if NULL, start at the
2691 beginning; if non-NULL, start with the pattern variable after that
2692 position, and return the next matching pattern.
2693 (create_pattern_var): Create a unique instance of
2694 pattern-specific variables for every definition in the makefile.
2695 Don't combine the same pattern together. This allows us to
2696 process the variable handling properly even when the same pattern
2697 is used multiple times.
2698 (parse_variable_definition): New function: break out the parsing
2699 of a variable definition line from try_variable_definition.
2700 (try_variable_definition): Call parse_variable_definition to
2701 parse.
2702 (print_variable_data_base): Print out pattern-specific variables.
2703 * variable.h (struct variable): Remember when a variable is
2704 conditional. Also remember its flavor.
2705 (struct pattern_var): Instead of keeping a variable set, we just
2706 keep a single variable for each pattern.
2707 * read.c (record_target_var): Each pattern variable contains only a
2708 single variable, not a set, so create it properly.
2709 * doc/make.texi (Pattern-specific): Document the new behavior.
2711 2003-04-17 Paul D. Smith <psmith@gnu.org>
2713 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2714 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2715 file/directory naming rules for VMS so I can't tell whether this
2716 is correct or not.
2718 2003-04-09 Paul D. Smith <psmith@gnu.org>
2720 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2721 DOS-style pathnames: backslash separators and drive specifiers.
2723 2003-03-28 Paul D. Smith <psmith@gnu.org>
2725 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2726 the intermediate flag on all targets. Fixes bug #2515.
2728 2003-03-24 Paul D. Smith <psmith@gnu.org>
2730 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2731 Upgrade to autoconf 2.57 and automake 1.7.3.
2733 * job.c: More OS/2 changes from Andreas Buening.
2735 * file.c (print_file): Fix variable initialization.
2736 Fixes bug #2892.
2738 * remake.c (notice_finished_file):
2740 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2741 some calls (like readdir()) return NULL in valid situations
2742 without resetting errno. Fixes bug #2846.
2744 2003-02-25 Paul D. Smith <psmith@gnu.org>
2746 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2748 * job.c (_is_unixy_shell) [OS/2]: New function.
2749 Set default shell to /bin/sh.
2750 (reap_children): Close the job_rfd pipe here since we don't use a
2751 SIGCHLD handler.
2752 (set_child_handler_action_flags): define this to empty on OS/2.
2753 (start_job_command): Close the jobserver pipe and use
2754 child_execute_job() instead of fork/exec.
2755 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2756 rather than exec'ing, then reconfigure stdin/stdout.
2757 (exec_command): Rewrite to use spawn instead of exec. Return the
2758 PID of the child.
2760 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2761 in DOS. Handle the TEMP environment variable as in DOS. Don't
2762 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2763 use -j in DOS mode. Use child_execute_job() instead of
2764 exec_command().
2766 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2767 spawn() instead.
2769 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2770 prototypes that return values.
2772 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2774 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2775 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2776 for OS/2.
2777 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2778 DOS paths.
2780 2003-02-24 Paul D. Smith <psmith@gnu.org>
2782 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2783 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2784 (child_execute_job) [VMS]: Handle error status properly.
2785 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2787 * function.c (func_shell): Use EINTRLOOP() while reading from the
2788 subshell pipe (Fixes bug #2502).
2789 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2790 jobserver pipe.
2791 * main.c (main): Ditto.
2793 2003-01-30 Paul D. Smith <psmith@gnu.org>
2795 * read.c (eval): eval() was not fully reentrant, because the
2796 collapsed buffer was static. Change it to be an automatic
2797 variable so that eval() can be invoked recursively.
2798 Fixes bug # 2238.
2799 (eval): Apply patch # 1022: fix memory reference error on long
2800 target-specific variable lines.
2801 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2803 * function.c (check_numeric): Combine the is_numeric() function
2804 into this function, since it's only called from one place.
2805 Constify this function. Have it print the incorrect string in the
2806 error message. Fixes bug #2407.
2807 (strip_whitespace): Constify.
2808 (func_if): Constify.
2809 * expand.c (expand_argument): Constify.
2811 2003-01-29 Paul D. Smith <psmith@gnu.org>
2813 Fix bug # 2169, also reported by other people on various systems.
2815 * make.h: Some systems, such as Solaris and PTX, do not fully
2816 implement POSIX-compliant SA_RESTART functionality; important
2817 system calls like stat() and readdir() can still fail with EINTR
2818 even if SA_RESTART has been set on the signal handler. So,
2819 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2820 EINTR for system calls which return -1 or 0 (NULL), respectively,
2821 on error.
2822 Also, remove the old atomic_stat()/atomic_readdir() and
2823 HAVE_BROKEN_RESTART handling.
2825 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2827 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2828 * remake.c (touch_file): Ditto.
2830 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2831 * read.c (construct_include_path): Ditto.
2832 * remake.c (name_mtime): Ditto.
2833 * vpath.c (selective_vpath_search): Ditto.
2834 * dir.c (find_directory): Ditto.
2835 (local_stat): Ditto.
2836 (find_directory): Use ENULLLOOP() to wrap opendir().
2837 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2839 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2840 atomic_readdir() handling.
2842 2003-01-22 Paul D. Smith <psmith@gnu.org>
2844 * function.c (func_call): Fix Bug #1744. If we're inside a
2845 recursive invocation of $(call ...), mask any of the outer
2846 invocation's arguments that aren't used by this one, so that this
2847 invocation doesn't "inherit" them accidentally.
2849 2002-12-05 Paul D. Smith <psmith@gnu.org>
2851 * function.c (subst_expand): Valery Khamenia reported a
2852 pathological performance hit when doing substitutions on very
2853 large values with lots of words: turns out we were invoking
2854 strlen() a ridiculous number of times. Instead of having each
2855 call to sindex() call strlen() again, keep track of how much of
2856 the text we've seen and pass the length to sindex().
2858 2002-11-19 Paul D. Smith <psmith@gnu.org>
2860 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2863 2002-11-16 Paul D. Smith <psmith@gnu.org>
2865 * NMakefile.template (OBJS): Add hash.c object file.
2866 * SMakefile.template (srcs): Ditto.
2867 * Makefile.ami (objs): Ditto.
2868 * build_w32.bat: Ditto.
2870 * Makefile.DOS.template: Remove extra dependencies.
2872 2002-10-25 Paul D. Smith <psmith@gnu.org>
2874 * expand.c (install_variable_buffer): New function. Install a new
2875 variable_buffer context and return the previous one.
2876 (restore_variable_buffer): New function. Free the current
2877 variable_buffer context and put a previously saved one back.
2878 * variable.h: Prototypes for {install,restore}_variable_buffer.
2879 * function.c (func_eval): Push a new variable_buffer context
2880 before we eval, then restore the old one when we're done.
2881 Fixes Bug #1517.
2883 * read.c (install_conditionals): New function. Install a new
2884 conditional context and return the previous one.
2885 (restore_conditionals): New function. Free the current
2886 conditional context and put a previously saved one back.
2887 (eval): Use the {install,restore}_conditionals for "include"
2888 handling.
2889 (eval_buffer): Use {install,restore}_conditionals to preserve the
2890 present conditional state before we evaluate the buffer.
2891 Fixes Bug #1516.
2893 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2894 and $(value ...).
2895 (Recursion): Add a variable index entry for CURDIR.
2897 * README.cvs: Update to appropriate versions.
2898 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2899 don't need to copy loadavg.c: automake is smart enough to create
2900 it for me. Still have a bug in automake related to ansi2knr tho.
2902 2002-10-14 Paul D. Smith <psmith@gnu.org>
2904 * remake.c (notice_finished_file): Only touch targets if they have
2905 at least one command (as per POSIX). Resolve Bug #1418.
2907 * *.c: Convert to using ANSI C-style function definitions.
2908 * Makefile.am: Enable the ansi2knr feature of automake.
2909 * configure.in: ditto.
2911 2002-10-13 Paul D. Smith <psmith@gnu.org>
2913 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2914 for automatic variable values like $^, etc. In the case of very
2915 large lists of prerequisites this causes problems. Instead reuse
2916 a static buffer (resizeable) for each variable.
2918 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2919 target-specific variable definitions. Check for it and set an
2920 "exported" flag.
2921 (record_target_var): Set the export field to v_export if the
2922 "exported" flag is set.
2923 * doc/make.texi (Target-specific): Document the ability to use
2924 "export".
2926 * doc/make.texi: Change the name of the section on automatic
2927 variables from "Automatic" to "Automatic Variables". Added text
2928 clarifying the scope of automatic variables.
2930 2002-10-04 Paul D. Smith <psmith@gnu.org>
2932 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2933 as () braces.
2934 (record_files): Ditto.
2936 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2937 the search for the '=' to only within the enclosing parens.
2939 2002-10-03 Paul D. Smith <psmith@gnu.org>
2941 Version 3.80 released.
2943 * dir.c: Change hash functions to use K&R function definition style.
2944 * function.c: Ditto.
2945 * read.c: Ditto.
2946 * variable.c: Ditto.
2948 Update to automake 1.7.
2950 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2951 (pdf): Remove this target as automake now provides one.
2953 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2955 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2957 * makefile.com: Updates for GNU make 3.80.
2958 * makefile.vms: Ditto.
2960 2002-09-23 Paul D. Smith <psmith@gnu.org>
2962 * read.c (enum make_word_type): Remove w_comment.
2963 (get_next_mword): Don't treat comment characters as special; where
2964 this function is used we will never see a comment (it's stripped
2965 before we get here) and treating comments specially means that
2966 targets like "foo\#bar" aren't handled properly.
2968 2002-09-18 Paul D. Smith <psmith@gnu.org>
2970 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2972 * read.c (eval): Expansion of arguments to export/unexport was
2973 ignoring all arguments after the first one. Change the algorithm
2974 to expand the whole line once, then parse the results.
2976 2002-09-17 Paul D. Smith <psmith@gnu.org>
2978 Fix Bug #940 (plus another bug I found while looking at this):
2980 * read.c (record_target_var): enter_file() will add a new entry if
2981 it's a double-colon target: we don't want to do that in this
2982 situation. Invoke lookup_file() and only enter_file() if it does
2983 not already exist. If the file we get back is a double-colon then
2984 add this variable to the "root" double-colon target.
2986 * variable.c (initialize_file_variables): If this file is a
2987 double-colon target but is not the "root" target, then initialize
2988 the root and make the root's variable list the parent of our
2989 variable list.
2991 2002-09-13 Paul D. Smith <psmith@gnu.org>
2993 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2995 * hash.c (round_up_2): Get rid of a warning.
2997 2002-09-12 Paul D. Smith <psmith@gnu.org>
2999 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3000 so it doesn't complain about getloadavg.c.
3002 * commands.c (set_file_variables): Make sure we always alloca() at
3003 least 1 character for the value of $? (for '\0').
3005 2002-09-11 Paul D. Smith <psmith@gnu.org>
3007 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3008 macro to use RESULT instead of the incorrect _RESULT_.
3010 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3011 and atomic_readdir(). We need to #include dirent.h to get this to
3012 work.
3013 * misc.c (atomic_readdir): Fix typos.
3015 2002-09-10 Paul D. Smith <psmith@gnu.org>
3017 * read.c (eval): Expand variable lists given to export and
3018 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3019 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3021 * doc/make.texi (Variables/Recursion): Document this.
3022 (Conditional Syntax): And here.
3024 2002-09-09 Paul D. Smith <psmith@gnu.org>
3026 * configure.in: Check for memmove().
3028 2002-09-07 Paul D. Smith <psmith@gnu.org>
3030 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3031 Michael Sterrett <msterret@coat.com> reports that while it has
3032 SA_RESTART, it does not work properly.
3034 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3035 that invokes stat() and loops to do it again if it returns EINTR.
3036 (atomic_readdir): Ditto, with readdir().
3038 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3039 and readdir() to atomic_stat() and atomic_readdir().
3041 2002-09-04 Paul D. Smith <psmith@gnu.org>
3043 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3044 reports that GNU make sometimes doesn't recognize that targets can
3045 be made, when directories can be created as prerequisites. He
3046 reports that changing the order of predicates in the DEP->changed
3047 flag test so that lookup_file() is always performed, solves this
3048 problem.
3050 2002-08-08 Paul D. Smith <psmith@gnu.org>
3052 * configure.in: Require a newer version of gettext.
3054 * misc.c (perror_with_name): Translate the format string (for
3055 right-to-left language support).
3056 (pfatal_with_name): Ditto.
3058 * main.c: Create a static array of strings to store the usage
3059 text. This is done to facilitate translations.
3060 (struct command_switch): Remove argdesc and description fields.
3061 (switches): Remove values for obsolete fields.
3062 (print_usage): Print each element of the usage array.
3064 * hash.c: Change function definitions to be K&R style.
3066 2002-08-02 Paul D. Smith <psmith@gnu.org>
3068 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3069 this one because it's too hard to get right. We'll look at it for
3070 a future release.
3071 * main.c (main): Don't create the .TARGETS variable.
3072 * variable.c (handle_special_var): Don't handle .TARGETS.
3074 2002-08-01 Paul D. Smith <psmith@gnu.org>
3076 * main.c (switches): Add a new option, -B (--always-make). If
3077 specified, make will rebuild all targets that it encounters even
3078 if they don't appear to be out of date.
3079 (always_make_flag): New flag.
3080 * make.h: Extern always_make_flag.
3081 * remake.c (update_file_1): Check always_make_flag; if it's set we
3082 will always rebuild any target we can, even if none of its
3083 prerequisites are newer.
3084 * NEWS: Mention it.
3086 * doc/make.texi (Shell Function): Make it clear that make
3087 variables marked as "export" are not passed to instances of the
3088 shell function.
3090 Add new introspection variable .VARIABLES and .TARGETS.
3092 * variable.c (handle_special_var): New function. If the variable
3093 reference passed in is "special" (.VARIABLES or .TARGETS),
3094 calculate the new value if necessary. .VARIABLES is handled here:
3095 walk through the hash of defined variables and construct a value
3096 which is a list of the names. .TARGETS is handled by
3097 build_target_list().
3098 (lookup_variable): Invoke handle_special_var().
3099 * file.c (build_target_list): Walk through the hask of known files
3100 and construct a list of the names of all the ones marked as
3101 targets.
3102 * main.c (main): Initialize them to empty (and as simple variables).
3103 * doc/make.texi (Special Variables): Document them.
3104 * NEWS: Mention them.
3106 * variable.h (struct variable): Add a new flag "exportable" which
3107 is true if the variable name is valid for export.
3108 * variable.c (define_variable_in_set): Set "exportable" when a new
3109 variable is defined.
3110 (target_environment): Use the "exportable" flag instead of
3111 re-checking the name here... an efficiency improvement.
3113 2002-07-31 Paul D. Smith <psmith@gnu.org>
3115 * config.h-vms.template: Updates to build on VMS. Thanks to
3116 Brian_Benning@aksteel.com for helping verify the build.
3117 * makefile.com: Build the new hash.c file.
3118 * hash.h: Use strcpmi(), not stricmp(), in the
3119 HAVE_CASE_INSENSITIVE_FS case.
3121 2002-07-30 Paul D. Smith <psmith@gnu.org>
3123 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3124 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3125 Reported by <Brian_Benning@aksteel.com>.
3127 2002-07-10 Paul D. Smith <psmith@gnu.org>
3129 * variable.c (pop_variable_scope): Remove variable made unused by
3130 new hash infrastructure.
3131 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3132 comparisons as well as name comparisons.
3133 * variable.h: Add a prototype for new hash_init_function_table().
3134 * file.c (lookup_file): Remove variables made unused by new hash
3135 infrastructure.
3136 * dir.c (directory_contents_hash_2): Missing return of hash value.
3137 (dir_contents_file_exists_p): Remove variables made unused by new
3138 hash infrastructure.
3141 Installed Greg McGary's integration of the hash functions from the
3142 GNU id-utils package:
3144 2002-07-10 Greg McGary <greg@mcgary.org>
3146 * scripts/functions/filter-out: Add literals to to the
3147 pattern space in order to add complexity, and trigger
3148 use of an internal hash table. Fix documentation strings.
3149 * scripts/targets/INTERMEDIATE: Reverse order of files
3150 passed to expected `rm' command.
3152 2002-07-10 Greg McGary <greg@mcgary.org>
3154 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3155 * hash.c: New file, taken from id-utils.
3156 * hash.h: New file, taken from id-utils.

3168 * ar.c (ar_name): Delay call to strlen until needed.
3169 * main.c (initialize_global_hash_tables): New function.
3170 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3171 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3172 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
3174 * dir.c (hash.h): New #include.
3175 (struct directory_contents) [next, files]: Remove members.
3176 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

3186 (find_directory): Use new hash table package.
3187 (dir_contents_file_exists_p): Likewise.

3206 function_table_entry_hash_cmp): New functions.
3207 (lookup_function): Remove `table' argument.
3208 Use new hash table package.
3209 (struct a_word) [chain, length]: New members.
3210 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3211 (struct a_pattern): New struct.
3212 (func_filter_filterout): Pass through patterns noting boundaries
3213 and '%', if present. Note a_word length. Use a hash table if
3214 arglists are large enough to justify cost.
3215 (function_table_init): Renamed from function_table.
3216 (function_table): Declare as `struct hash_table'.
3217 (FUNCTION_TABLE_ENTRIES): New constant.

3223 (uniquize_deps): Use hash table to efficiently identify duplicates.
3224 (find_char_unquote): Accept two char-constant stop chars, rather
3225 than a string constant, avoiding zillions of calls to strchr.
3226 Tighten inner search loops to test only for desired delimiters.
3228 * variable.c (variable_hash_1, variable_hash_2,
3229 variable_hash_cmp): New functions.

3242 (print_variable_set): Likewise.
3244 2002-07-10 Paul D. Smith <psmith@gnu.org>
3246 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3247 prerequisite list. A real SysV make will expand the entire
3248 prerequisites list _twice_: we don't do that as it's a big
3249 backward-compatibility problem. We only replace those specific
3250 variables.
3252 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3253 references left in the list of prerequisites. Check for .POSIX as
3254 we record targets, so we can disable non-POSIX behavior while
3255 reading makefiles as well as running them.
3256 (eval): Check the prerequisite list to see if we have anything
3257 that looks like a SysV prerequisite variable reference.
3259 2002-07-09 Paul D. Smith <psmith@gnu.org>
3261 * doc/make.texi (Prerequisite Types): Add a new section describing
3262 order-only prerequisites.
3264 * read.c (uniquize_deps): If we have the same file as both a
3265 normal and order-only prereq, get rid of the order-only prereq,
3266 since the normal one supersedes it.
3268 2002-07-08 Paul D. Smith <psmith@gnu.org>
3270 * AUTHORS: Added Greg McGary to the AUTHORS file.
3271 * NEWS: Blurbed order-only prerequisites.
3272 * file.c (print_file): Show order-only deps properly when printing
3273 the database.
3275 * maintMakefile: Add "update" targets for wget'ing the latest
3276 versions of various external files. Taken from Makefile.maint in
3277 autoconf, etc.
3279 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3280 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3282 2002-07-07 Paul D. Smith <psmith@gnu.org>
3284 * po/*.po: Remove. We'll use wget to retrieve them at release
3285 time.
3287 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3288 rather than a shell you get an exception. Make sure we look up
3289 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3291 * remake.c (notice_finished_file): Fix handling of -t flag.
3292 Patch provided by Henning Makholm <henning@makholm.net>.
3294 * implicit.c (pattern_search): Some systems apparently run short
3295 of stack space, and using alloca() in this function caused an
3296 overrun. I modified it to use xmalloc() on the two variables
3297 which seemed like they might get large. Fixes Bug #476.
3299 * main.c (print_version): Update copyright notice to conform with
3300 GNU standards.
3301 (print_usage): Update help output.
3303 * function.c (func_eval): Create a new make function, $(eval
3304 ...). Expand the arguments, put them into a buffer, then invoke
3305 eval_buffer() on the resulting string.
3306 (func_quote): Create a new function, $(quote VARNAME). Inserts
3307 the value of the variable VARNAME without expanding it any
3308 further.
3310 * read.c (struct ebuffer): Change the linebuffer structure to an
3311 "eval buffer", which can be either a file or a buffer.
3312 (eval_makefile): Move the code in the old read_makefile() which
3313 located a makefile into here: create a struct ebuffer with that
3314 information. Have it invoke the new function eval() with that
3315 ebuffer.
3316 (eval_buffer): Create a new function that creates a struct ebuffer
3317 that holds a string buffer instead of a file. Have it invoke
3318 eval() with that ebuffer.
3319 (eval): New function that contains the guts of the old
3320 read_makefile() function: this function parses makefiles. Obtains
3321 data to parse from the provided ebuffer. Some modifications to
3322 make the flow of the function cleaner and clearer. Still could
3323 use some work here...
3324 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3325 contents of the define/endef variable from the ebuffer.
3326 (readstring): Read the next line from a string-style ebuffer.
3327 (readline): Read the next line from an ebuffer. If it's a string
3328 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3329 from the file.
3331 * dep.h (eval_buffer): Prototype eval_buffer();
3333 * variable.c (do_variable_definition): Make sure that all
3334 non-target-specific variables are registered in the global set.
3335 If we're invoked from an $(eval ...) we might be inside a $(call
3336 ...) or other function which has pushed a variable scope; we still
3337 want to define our variables from evaluated makefile code in the
3338 global scope.
3340 2002-07-03 Greg McGary <greg@mcgary.org>
3342 * dep.h (struct dep) [ignore_mtime]: New member.
3343 [changed]: convert to a bitfield.
3344 * implicit.c (pattern_search): Zero ignore_mtime.
3345 * main.c (main, handle_non_switch_argument): Likewise.
3346 * rule.c (convert_suffix_rule): Likewise.
3347 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3348 (read_makefile): Parse '|' in prerequisite list.
3349 (uniquize_deps): Consider ignore_mtime when comparing deps.
3350 * remake.c (update_file_1, check_dep): Don't force remake for
3351 dependencies that have d->ignore_mtime.
3352 * commands.c (FILE_LIST_SEPARATOR): New constant.
3353 (set_file_variables): Don't include a
3354 prerequisite in $+, $^ or $? if d->ignore_mtime.
3355 Define $|.
3357 2002-06-18 Paul D. Smith <psmith@gnu.org>
3359 * make.texinfo: Updates for next revision. New date/rev/etc.
3360 Recreate all Info menus. Change license on the manual to the GNU
3361 Free Documentation License. A number of typos.
3362 (Variables Simplify): Don't use "-" before it's defined.
3363 (Automatic Prerequisites): Rewrite the target example to work
3364 properly if the compile fails. Remove incorrect comments about
3365 how "set -e" behaves.
3366 (Text Functions): Move the "word", "wordlist", "words", and
3367 "firstword" functions here, from "File Name Functions".
3368 * make-stds.texi: Update from latest GNU version.
3369 * fdl.texi: (created) Import the latest GNU version.
3371 2002-06-06 Paul D. Smith <psmith@gnu.org>
3373 * variable.c (do_variable_definition): New function: extract the
3374 part of try_variable_definition() that actually sets the value
3375 into a separate function.
3376 (try_variable_definition): Call do_variable_definition() after
3377 parsing the variable definition string.
3378 (define_variable_in_set): Make the name argument const.
3380 * variable.h (enum variable_flavor): Make public.
3381 (do_variable_definition): Create prototype.
3383 * read.c (read_all_makefiles): Create a new built-in variable,
3384 MAKEFILE_LIST.
3385 (read_makefile): Add each makefile read in to this variable value.
3387 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3389 * Makefile.DOS.template: Tweak according to changes in the
3390 distribution. Add back the dependencies of *.o files.
3392 * configh.dos.template: Synchronize with config.h.in.
3394 2002-05-09 Paul D. Smith <psmith@gnu.org>
3396 * file.c (file_timestamp_now): Use K&R function declaration.
3398 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3399 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3400 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3401 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3402 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3403 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3404 nlist.n_name is a pointer rather than an array.
3406 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3407 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3408 * configure.in: Use it instead of the old version.
3410 * main.c (main): Prefer setvbuf() to setlinebuf().
3412 2002-05-08 Paul D. Smith <psmith@gnu.org>
3414 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3415 (loadavg_LDADD): Ditto.
3417 2002-04-29 Paul D. Smith <psmith@gnu.org>
3419 * expand.c (recursively_expand_for_file): Rename
3420 recursively_expand() to recursively_expand_for_file() and provide
3421 an extra argument, struct file. If the argument is provided, set
3422 the variable scope to that of the file before expanding.
3423 * variable.h (recursively_expand): Make this a macro that invokes
3424 recursively_expand_for_file() with a NULL file pointer.
3425 * variable.c (target_environment): Call the renamed function and
3426 provide the current file context.
3427 Fixes Debian bug #144306.
3429 2002-04-28 Paul D. Smith <psmith@gnu.org>
3431 Allow $(call ...) user-defined variables to be self-referencing
3432 without throwing an error. Allows implementation of transitive
3433 closures, among other possibly useful things.
3434 Requested by: Philip Guenther <guenther@sendmail.com>
3436 * variable.h (struct variable): Add a new field: exp_count, and
3437 new macros to hold its size and maximum value.
3438 (warn_undefined): Make this a macro.
3439 * variable.c (define_variable_in_set): Initialize it.
3440 * expand.c (recursively_expand): If we detect recursive expansion
3441 of a variable, check the exp_count field. If it's greater than 0
3442 allow the recursion and decrement the count.
3443 (warn_undefined): Remove this (now a macro in variable.h).
3444 * function.c (func_call): Before we expand the user-defined
3445 function, modify its exp_count field to contain the maximum
3446 number of recursive calls we'll allow. After the call, reset it
3447 to 0.
3449 2002-04-21 Paul D. Smith <psmith@gnu.org>
3451 Modified to use latest autoconf (2.53), automake (1.6.1), and
3452 gettext (0.11.1). We're using gettext's new "external" support,
3453 to avoid including libintl source with GNU make.
3455 * README.cvs: New file. Explain how to build GNU make from CVS.
3457 * configure.in: Modify checking for the system glob library.
3458 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3459 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3460 etc. will manage it correctly). Set an automake conditional
3461 USE_LOCAL_GLOB to decide whether to compile the glob library.
3463 * getloadavg.c (main): Include make.h in the "TEST" program to
3464 avoid warnings.
3466 * Makefile.am: Remove special rules for loadavg. Replace them
3467 with Automake capabilities for building extra programs.
3469 * signame.c: This file does nothing if the system provide
3470 strsignal(). If not, it implements strsignal(). If the system
3471 doesn't define sys_siglist, then we make our own; otherwise we use
3472 the system version.
3473 * signame.h: Removed.
3475 * main.c (main): No need to invoke signame_init(). Update copyright.
3477 * ABOUT-NLS: Removed.
3478 * gettext.c: Removed.
3479 * gettext.h: Get a simplified copy from the gettext package.
3480 * po/*: Created.
3481 * i18n/*.po: Moved to po/.
3482 * i18n/: Removed.
3484 * config/*: Created. Contains package configuration helper files.
3485 * config.guess, config.sub: Moved to config directory.
3487 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3488 Rework to use new-style autoconf features. Use the "external"
3489 mode for gettext. Make the build.sh config file conditional on
3490 whether build.sh.in exists, to avoid autoconf errors.
3491 * acinclude.m4: Removed almost all macros as being obsolete.
3492 Rewrote remaining macros to use AC_DEFINE.
3493 * acconfig.h: Removed.
3495 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3496 conditional to handle customs support. Remove special handling
3497 for i18n features.
3499 2002-04-20 Paul D. Smith <psmith@gnu.org>
3501 * function.c (func_call): Don't mark the argument variables $1,
3502 etc. as recursive. They've already been fully expanded so
3503 there's no need to do it again, and doing so strips escaped $'s.
3504 Reported by Sebastian Glita <glseba@yahoo.com>.
3506 * remake.c (notice_finished_file): Walk through double-colon
3507 entries via the prev field, not the next field!
3508 Reported by Greg McGary <greg@mcgary.org>.
3510 * main.c (main): If the user specifies -q and asks for a specific
3511 target which is a makefile, we got an assert. In that case it
3512 turns out we should continue normally instead.
3514 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3516 * i18n/he.po: Installed a new translation.
3518 2002-01-07 Paul D. Smith <psmith@gnu.org>
3520 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3522 2001-12-04 Paul D. Smith <psmith@gnu.org>
3524 * i18n/ja.po: Installed an updated translation.
3526 2001-09-06 Paul Eggert <eggert@twinsun.com>
3528 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3529 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3531 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3532 are available.
3533 (main): Get rid of any avoidable limit on stack size.
3535 2001-09-04 Paul D. Smith <psmith@gnu.org>
3537 * i18n/da.po: Installed an updated translation.
3539 2001-08-03 Paul D. Smith <psmith@gnu.org>
3541 * i18n/fr.po: Installed an updated translation.
3542 Resolves Debian bug #106720.
3544 2001-06-13 Paul D. Smith <psmith@gnu.org>
3546 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3547 translation.
3549 2001-06-11 Paul D. Smith <psmith@gnu.org>
3551 * i18n/ko.po: Installed a new translation.
3553 2001-05-06 Paul D. Smith <psmith@gnu.org>
3555 Modify the EINTR handling.
3557 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3558 the way in which we manage the file descriptor/signal handler race
3559 trap to be more efficient.
3561 2001-05-06 Paul Eggert <eggert@twinsun.com>
3563 Restart almost all system calls that are interrupted, instead
3564 of worrying about EINTR. The lone exception is the read() for
3565 job tokens.
3567 * configure.in (HAVE_SA_RESTART): New macro.
3568 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3569 * main.c (main): Use SA_RESTART instead of the old,
3570 nonstandard SA_INTERRUPT.
3572 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3573 * main.c (bsd_signal): New function or macro,
3574 if the implementation doesn't supply it.
3575 (The bsd_signal function will be in POSIX 1003.1-200x.)
3576 (HANDLESIG): Remove.
3577 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3579 * make.h (EINTR_SET): Remove.
3580 (SA_RESTART): New macro.
3582 * arscan.c (ar_member_touch): Don't worry about EINTR.
3583 * function.c (func_shell): Likewise.
3584 * job.c (reap_children, free_child, new_job): Likewise.
3585 * main.c (main): Likewise.
3586 * remake.c (touch_file, name_mtime): Likewise.
3588 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3589 if fstat failed with errno!=EINTR, the error was ignored.
3591 * job.c (set_child_handler_action_flags): New function.
3592 (new_job): Use it to temporarily clear the SIGCHLD action flags
3593 while reading the token.
3595 2001-05-02 Paul D. Smith <psmith@gnu.org>
3597 * job.c (start_job_command): Don't add define/endef per-line flags
3598 to the top-level flags setting.
3600 2001-04-03 Paul D. Smith <psmith@gnu.org>
3602 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3603 bit on error, so check for odd return values, not non-0 return
3604 values.
3605 (VMS_get_member_info): Calculate the timezone differences correctly.
3606 Reported by John Fowler <jfowler@nyx.net>.
3609 2001-03-14 Paul D. Smith <psmith@gnu.org>
3611 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3612 value before invoking define_variable().
3613 Reported by John Fowler <jfowler@nyx.net>.
3615 2001-02-07 Paul D. Smith <psmith@gnu.org>
3617 * read.c (record_target_var): If we reset the variable due to a
3618 command-line variable setting overriding it, turn off the "append"
3619 flag.
3621 2001-01-17 Paul D. Smith <psmith@gnu.org>
3623 * variable.c (lookup_variable) [VMS]: When getting values from the
3624 environment, allocate enough space for the _value_ plus escapes,
3625 not enough space for the name plus escapes :-/.
3626 Reported by John Fowler <jfowler@nyx.net>.
3628 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3629 warnings that make generates, so it doesn't look like an error.
3630 Reported by Karl Berry <karl@gnu.org>.
3633 Fix for PR/2020: Rework appended target-specific variables. I'm
3634 fairly confident this algorithm is finally correct.
3636 * expand.c (allocated_variable_append): Rewrite. Instead of
3637 expanding each appended variable then adding all the expanded
3638 strings together, we append all the unexpanded values going up
3639 through the variable set contexts, then expand the final result.
3640 This behaves just like non-target-specific appended variable
3641 values, while the old way didn't in various corner cases.
3642 (variable_append): New function: recursively append the unexpanded
3643 value of a variable, walking from the outermost variable scope to
3644 the innermost.
3645 * variable.c (lookup_variable): Remove the code that looked up the
3646 variable set list if the found variable was "append". We don't
3647 need this anymore.
3648 (lookup_variable_in_set): Make this non-static so we can use it
3649 elsewhere.
3650 (try_variable_definition): Use lookup_variable_in_set() rather
3651 than faking out current_variable_set_list by hand (cleanup).
3652 * variable.h: Add a prototype for the now non-static
3653 lookup_variable_in_set().
3655 2000-11-17 Paul D. Smith <psmith@gnu.org>
3657 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3658 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3659 before throwing a fit.
3661 2000-11-17 Paul D. Smith <psmith@gnu.org>
3663 * read.c (readline): CRLF calculations had a hole, if you hit the
3664 buffer grow scenario just right. Reworked the algorithm to avoid
3665 the need for len or lastlen at all. Problem description with
3666 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3668 2000-10-24 Paul D. Smith <psmith@gnu.org>
3670 * gettext.c (SWAP): Declare this with the prototype, otherwise
3671 some systems don't work (non-32-bit? Reported for Cray T3E).
3672 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3674 2000-10-05 Paul D. Smith <psmith@gnu.org>
3676 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3677 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3679 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3681 2000-09-22 Paul D. Smith <psmith@gnu.org>
3683 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3684 parts of the real gettext.h here, and we expect to really include
3685 the real gettext.h later. If we keep this #define, it's ignored.
3687 2000-09-21 Paul D. Smith <psmith@gnu.org>
3689 * main.c (log_working_directory): Rework the text to use complete
3690 sentences, to make life simpler for the translators.
3692 2000-08-29 Paul D. Smith <psmith@gnu.org>
3694 * file.c (remove_intermediates): Print a debug message before we
3695 remove intermediate files, so the user (if she uses -d) knows
3696 what's going on.
3698 2000-08-21 Paul D. Smith <psmith@gnu.org>
3700 * variable.c (try_variable_definition): Change how we handle
3701 target-specific append variable defns: instead of just setting the
3702 value, expand it as an append _but_ only within the current
3703 target's context. Otherwise we lose all but the last value if the
3704 variable is appended more than once within the current target
3705 context. Fixes PR/1831.
3707 2000-08-16 Paul D. Smith <psmith@gnu.org>
3709 * function.c (func_shell): Nul-terminate the buffer before
3710 printing an exec error message (just in case it's not!).
3711 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3713 2000-07-25 Paul D. Smith <psmith@gnu.org>
3715 * job.c (construct_command_argv_internal): Add "~" to the list of
3716 sh_chars[] which disallow optimizing out the shell call.
3718 2000-07-23 Paul Eggert <eggert@twinsun.com>
3720 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3721 supersedes --disable-nsec-timestamps.
3722 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3723 * README: Remove --disable-nsec-timestamps.
3725 * filedef.h (struct file.low_resolution_time): New member.
3726 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3727 * remake.c (update_file_1):
3728 Avoid spurious rebuilds due to low resolution time stamps,
3729 generalizing the earlier code that applied only to archive members.
3730 (f_mtime): Archive members always have low resolution time stamps.
3732 * configure.in: Remove --disable-nsec-timestamps, as this has
3733 been superseded by .LOW_RESOLUTION_TIME.
3735 2000-07-23 Paul Eggert <eggert@twinsun.com>
3737 * configure.in (enable_nsec_timestamps): Renamed from
3738 make_cv_nsec_timestamps, since enable/disable options
3739 shouldn't be cached.
3741 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3742 and Paul Eggert <eggert@twinsun.com>
3744 * file.c (file_timestamp_now):
3745 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3746 so that clock_gettime is not linked unless needed.
3748 * filedef.h (FILE_TIMESTAMP_HI_RES):
3749 Remove definition; "configure" now does this.
3751 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3752 to before high resolution file timestamp check,
3753 since that check now uses uintmax_t.
3754 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3755 high resolution file timestamps.
3756 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3757 so that we don't link in clock_gettime unnecessarily.
3759 2000-07-17 Paul D. Smith <psmith@gnu.org>
3761 * i18n/ja.po: New version of the translation file.
3763 2000-07-07 Paul D. Smith <psmith@gnu.org>
3765 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3766 the offset calculation.
3767 (name_mtime): Replace EINTR test with EINTR_SET macro.
3769 2000-07-07 Paul Eggert <eggert@twinsun.com>
3771 Fix for PR/1811:
3773 * remake.c (update_file_1):
3774 Avoid spurious rebuilds of archive members due to their
3775 timestamp resolution being only one second.
3776 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3777 the clock's resolution being lower than file timestamps'.
3778 When warning about future timestamps, report only the discrepancy,
3779 not the absolute value of the timestamp and the current time.
3781 * file.c (file_timestamp_now): New arg RESOLUTION.
3782 * filedef.h (file_timestamp_now): Likewise.
3783 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3785 2000-07-05 Paul D. Smith <psmith@gnu.org>
3787 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3788 to listp. Fixes PR/1793.
3790 2000-06-26 Paul Eggert <eggert@twinsun.com>
3792 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3794 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3796 * remake.c (f_mtime): Remove unused var memtime.
3798 2000-06-25 Martin Buchholz <martin@xemacs.org>
3800 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3801 Ran spell-check on make.texinfo.
3803 2000-06-23 Paul D. Smith <psmith@gnu.org>
3805 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3806 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3807 * make.h: Define these macros.
3809 * Version 3.79.1 released.
3811 * configure.in: Add a new option, --disable-nsec-timestamps, to
3812 avoid using sub-second timestamps on systems that support it. It
3813 can lead to problems, e.g. if your makefile relies on "cp -p".
3814 * README.template: Document the issue with "cp -p".
3816 * config.guess, config.sub: Updated.
