1 2009-06-07 Paul Smith <psmith@gnu.org>
3 * read.c (record_files): The second-expansion "f->updating" hack
4 was not completely correct: if assumed that the target with
5 commands always had prerequisites; if one didn't then the ordering
6 was messed up. Fixed for now to use f->updating to decide whether
7 to preserve the last element in the deps list... but this whole
8 area of constructing and reversing the deps list is too confusing
9 and needs to be reworked. Fixes Savannah bug #21198.
11 2009-06-06 Paul Smith <psmith@gnu.org>
13 * hash.c (hash_insert): Remove useless test for NULL.
14 Fixes Savannah bug #21823.
16 * make.h: Move SET_STACK_SIZE determination to make.h.
17 * main.c (main): New global variable, STACK_LIMIT, holds the
18 original stack limit when make was started.
19 * job.c (start_job_command): Reset the stack limit, if we changed it.
20 Fixes Savannah bug #22010.
22 * remake.c (check_dep): Only set the target's state to not-started
23 if it's not already running. Found this while testing -j10 builds
24 of glibc: various targets were being rebuilt multiple times.
25 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
28 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
29 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
32 2009-06-04 Paul Smith <psmith@gnu.org>
34 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
36 * maintMakefile: Modify access of config and gnulib Savannah
37 modules to use GIT instead of CVS.
39 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
40 Fixes Savannah bug #24655.
42 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
43 this can happen during some invocations of $(eval ...) for example.
44 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
46 2009-06-02 Paul Smith <psmith@gnu.org>
48 * configure.in: Check for fileno()
49 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
50 for the makefile file so invocations of $(shell ...) don't inherit it.
51 Fixes Savannah bug #24277.
53 2009-06-01 Paul Smith <psmith@gnu.org>
55 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
56 expansion was handled incorrectly. Rework the default goal
57 handling to save the variable only. Remove default_goal_file and
59 * read.c (eval): Check default_goal_var, not default_goal_name.
60 * read.c (record_target_var): Don't check default_goal_file here.
62 2009-05-31 Paul Smith <psmith@gnu.org>
64 * main.c (main): Expand the .DEFAULT_GOAL variable before using
65 it, and if the multi_glob() returns nothing (say it expanded to
66 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
68 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
69 $(and ..) to the reference. Fixes Savannah bug #25694.
71 * make.1: Be clear that some recipes will be executed even with -n.
72 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
74 * doc/make.texi (Override Directive): Make more clear how
75 overrides and appends interact.
76 Elucidates part of Savannah bug #26207.
78 * read.c (record_target_var): Don't reset the origin on
79 target-specific variables; try_variable_definition() will handle
80 this correctly. Fixes Savannah bug #26207.
82 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
83 Fixes Savannah bug #25712.
85 * implicit.c (pattern_search): Keep a pointer to the beginning of
86 the filename and save that instead of the constructed pointer.
87 Fixes Savannah bug #26593.
88 Patch by Mark Seaborn <mrs@mythic-beasts.com>
90 2009-05-30 Paul Smith <psmith@gnu.org>
92 * doc/make.texi (Multi-Line): Add a description of the new abilities
93 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
94 "command sequence" vs. "recipe" syntax.
95 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
96 after a define, to create variables with those flavors.
98 2009-05-25 Paul Smith <psmith@gnu.org>
100 Reworked the parser for variable assignments to allow multiple
101 modifiers, and in any order. Also allows variable and
102 prerequisites to be modifier names ('export', 'private', etc.)
104 * NEWS: Add notes about user-visible changes.
106 * read.c (struct vmodifiers): Remember what modifiers were seen.
107 (parse_var_assignment): New function to parse variable assignments.
108 (eval): Call the new function. Handle variable assignments earlier.

111 (assign_variable_definition): Call parse, then create the var.
113 2009-05-24 Paul Smith <psmith@gnu.org>
115 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
116 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
118 2009-03-14 Eli Zaretskii <eliz@gnu.org>
120 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
121 Fixes Savannah bug #25412.
123 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
124 prototype for xmalloc.
125 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
126 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
127 Loop over an array of extensions, instead of duplicating the same
128 code inline. Use SearchPath followed by CreateFile, instead of
129 the obsolete OpenFile. Fixes Savannah bug #17277.
130 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
131 to `find_file'. Fixes Savannah bug #25662.
133 2009-03-07 Eli Zaretskii <eliz@gnu.org>
135 * function.c (func_shell): Don't close pipedes[1] if it is -1.
136 Fixes Savannah bug #20495.
138 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
140 Introduce a new keyword "private" which applies to target-specific
141 variables and prevents their values from being inherited.
143 * variable.h (struct variable): Add private_var flag to each variable.
144 Add a flag to specify which list entry switches to the parent target.

151 * doc/make.texi (Suppressing Inheritance): Add documentation.
153 2008-10-26 Paul Smith <psmith@gnu.org>
155 * configure.in: Check for strndup().
156 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup

171 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
173 * job.c (construct_command_argv_internal): Avoid extra backslash
174 in batch-mode Unixy shells. Under DB_JOBS, display the contents
177 2008-05-31 Eli Zaretskii <eliz@gnu.org>
179 * README.W32.template: Remove obsolete text about non-support for
180 -jN without Unixy shell. Remove obsolete text about not supplying
181 Visual Studio project files (we do supply them). Modify text to
182 prefer GCC builds to MSC builds.
184 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
186 * doc/make.texi (Empty Targets): Fix typo.
188 2008-03-27 Paul Smith <psmith@gnu.org>
190 Fix Savannah bug #22379:
191 * ar.c (ar_glob_match): Zero the allocated structure.
192 * read.c (parse_file_seq): Ditto.
194 2008-03-08 Brian Dessent <brian@dessent.net>
196 * maintMakefile: Update Translation Project location.
198 2008-01-26 Eli Zaretskii <eliz@gnu.org>
200 * variable.c (target_environment): Don't use shell_var if its
201 `value' field is NULL.
203 2007-12-22 Eli Zaretskii <eliz@gnu.org>
205 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
207 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
208 (TEXINFOS): Value changed to `doc/make.texi'.
209 (.SUFFIXES): Use .texi instead of .texinfo.
210 (make.info, make.dvi): Depend on doc/make.texi.
211 (.texi.info): New target, instead of ".texinfo.info". Change -I
212 switch to $(MAKEINFO) to look in doc/. Use --no-split.
213 (.texi): New target, instead of ".texinfo". Change -I switch to
214 $(MAKEINFO) to look in doc/. Use --no-split.
215 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
216 switch to $(MAKEINFO) to look in doc/.
217 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
218 "*.i[0-9][0-9]" (due to --no-split above).
219 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
220 (html, make_1.html): New targets.
221 (.PHONY): Add "html".
222 (.SUFFIXES): Add .html.
224 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
226 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
227 HAVE_DECL_SYS_SIGLIST.
229 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
230 build does not use child_execute_job.
232 * variable.c (define_automatic_variables) [__MSDOS__]: Always
233 export the SHELL environment variable to the child.
235 2007-12-22 Eli Zaretskii <eliz@gnu.org>
237 * config.h.W32: Include sys/types.h.

247 lines", and "command script" to "recipe".
249 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
252 2007-10-27 Bruno Haible <bruno@clisp.org>
254 * remake.c (f_mtime): Print time difference values between 100 and
255 ULONG_MAX in fixed-point notation rather than in exponention notation.
257 2007-10-12 Eli Zaretskii <eliz@gnu.org>
259 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
260 a more complex value than a simple shell: if it's not a default
261 shell now then expand it and see if is a default shell then.
263 2007-10-10 Eli Zaretskii <eliz@gnu.org>
265 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
266 pathnames, with const strings.
267 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
268 from the template (used for building from CVS, not a dist).
270 2007-10-10 Paul Smith <psmith@gnu.org>
272 * make.h: Add a prototype for w32_kill() (change suggested by
273 Yongwei Wu <wuyongwei@gmail.com>).
275 2007-09-21 Eli Zaretskii <eliz@gnu.org>

285 Provided by Diego Biurrun <diego@biurrun.de>
287 2007-09-11 Paul Smith <psmith@gnu.org>
289 * doc/make.texi (Special Variables): Moved this into the "How to
290 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
291 (MAKEFILE_LIST) No longer a section; this was added into the
292 "Special Variables" section.
293 (Rule Introduction): Reference .RECIPEPREFIX.
294 (Simple Makefile): Ditto.
295 (Rule Syntax): Ditto.
296 (Command Syntax): Ditto.
297 (Error Messages): Ditto.
299 2007-09-10 Paul Smith <psmith@gnu.org>
301 * commands.c (print_commands): Don't print an extra line in the
302 command scripts. Prefix the command scripts with cmd_prefix, not \t.
304 * read.c (construct_include_path): Add the full string to the cache; we
305 were chopping the last char.
307 * NEWS: Announce the .RECIPEPREFIX special variable.
308 * variable.c (lookup_special_var): Rename from handle_special_var().
309 (lookup_variable): Call the new name.

314 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
315 * main.c (main): Create the .RECIPEPREFIX special variable.
316 * read.c (eval): Remove the cmd_prefix characters from the command
317 scripts here, so they're not stored in the commands array at all,
318 rather than waiting and stripping them out during command construction.
319 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
321 2007-08-15 Paul Smith <psmith@gnu.org>
323 * doc/make.texi (GNU Free Documentation License): The fdl.texi
324 file has had the section info removed, so add some to make.texi
325 before we include it.
327 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
329 * remake.c (check_dep): Reset the target state for intermediate
330 files. They might have been considered before but not updated
331 then (order-only for example) but they will be this time.

334 2007-07-21 Eli Zaretskii <eliz@gnu.org>
336 Fix Savannah bug #20549:
337 * function.c (func_shell): Call construct_command_argv with zero
339 * job.c (construct_command_argv_internal): New argument FLAGS; all
341 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
343 * job.h (construct_command_argv_internal): Update prototype.
345 2007-07-13 Paul Smith <psmith@gnu.org>
347 * file.c (expand_deps): Use variable_buffer as the start of the
348 buffer, not the original pointer (in case it was reallocated).
349 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
350 Fixes Savannah bug #20452.
352 2007-07-04 Paul Smith <psmith@gnu.org>
354 * (ALL FILES): Update to GPLv3.
355 * (ALL FILES): Update copyright for 2007.

361 * maintMakefile: Update Translation Project location.
363 2007-06-13 Paul Smith <psmith@gnu.org>
365 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
366 "Expansion of a deferred"
367 Fixes Savannah bug #20018.
369 * expand.c (variable_expand_for_file): Preserve the value of
370 reading_file rather than setting it to 0 at the end.
371 Fixes Savannah bug #20033.
373 2007-05-11 Paul Smith <psmith@gnu.org>
375 * job.c (new_job): Add debug info to specify where make found the
376 command script it is running to build a target.
377 Fixes Savannah bug #18617.
379 * default.c (default_suffixes,default_suffix_rules,default_variables):
380 Add support for Objective C. Fixes Savannah bug #16389.
381 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
383 * function.c (func_lastword): Initialize p.
385 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
386 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
387 Dave Korn <dave.korn@artimi.com>
389 2007-05-08 Paul Smith <psmith@gnu.org>
391 Fix Savannah bug #19656:
393 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
395 * make.h: Change all case-insensitive string compares to use
396 strcasecmp() (from POSIX). If we don't have that but do have one
397 of the others, define strcasecmp to be one of those instead. If
398 we don't have any, declare a prototype for our own version.
400 * misc.c (strcasecmp): Use this if we can't find any native
401 case-insensitive string comparison function.
402 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
403 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
405 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
406 strcasecmp() instead of stricmp().
407 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
408 instead of strcmpi().
409 * acinclude.m4: Remove the strcasecmp() check from here.
411 2007-03-21 Paul Smith <psmith@gnu.org>
413 * configure.in: Don't turn on case-insensitive file system support
414 if --disable-... is given. Fixes Savannah bug #19348.
416 2007-03-19 Paul Smith <psmith@gnu.org>
418 * ALL: Use the strcache for all file name strings, or other
419 strings which we will never free. The goal is to save memory by
420 avoiding duplicate copies of strings. However, at the moment this
421 doesn't save much memory in most situations: due to secondary
422 expansion we actually save prerequisite lists twice (once before
423 the secondary expansion, and then again after it's been parsed
424 into individual file names in the dep list). We will resolve this
425 in a future change, by doing the parsing up-front for targets
426 where secondary expansion is not set.
428 Moving things into the strcache also allows us to use const
429 pointers in many more places.
431 2007-01-03 Paul Smith <psmith@gnu.org>
433 * make.h (ENULLLOOP): Reset errno after each failed invocation of
434 the function, not just the first. Fixes Savannah bug #18680.
436 2006-11-18 Paul Smith <psmith@gnu.org>
438 * strcache.c (strcache_add_len): Don't allocate a new buffer
439 unless the string is not already nil-terminated. Technically this
440 is a violation of the standard, since we may be passed an array
441 that is not long enough to test one past. However, in make this
442 is never true since we only use nil-terminated strings or
445 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
447 * main.c: New global cmd_prefix, defaults to '\t'.
448 * job.c (construct_command_argv_internal): Use cmd_prefix instead
452 (dir_contents_file_exists_p): Check for an error return from
453 readdir(), just in case.
455 * commands.c: Constified.
456 * default.c: Constified.
457 * expand.c: Constified.
458 * function.c: Partial constification.
459 * variable.c: Partial constification.
460 * vmsify.c: Constification. Hard to test this but I hope I didn't
462 * vpath.c: Partial constification.
463 * w32/pathstuff.c: Partial constification.
465 2006-11-16 Eli Zaretskii <eliz@gnu.org>
467 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
468 backslashes and drive letters as absolute.
470 2006-10-22 Paul Smith <psmith@gnu.org>
472 * main.c (struct command_switch): Use const and void*.
474 2006-10-21 Paul Smith <psmith@gnu.org>
477 * arscan.c: Constified.
479 2006-09-30 Paul Smith <psmith@gnu.org>
481 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
482 point to lastword since the example was updated.
483 Fixes Savannah bug #16304.
484 (Secondary Expansion): Correct example description.
485 Fixes Savannah bug #16468.
486 (Makefile Contents): Clarify that comments cannot appear within
487 variable references or function calls.
488 Fixes Savannah bug #16577.
489 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
490 Fixes Savannah bug #17701.
491 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
492 (Prerequisite Types): Added an example of using order-only
493 prerequisites. Fixes Savannah bug #17880.
494 (Rule Syntax): "lise" -> "list"
495 (Multiple Rules): ... -> @dots{}
496 (Splitting Lines): ditto.
498 * remake.c (update_file_1): Prereqs that don't exist should be
499 considered changed, for the purposes of $?.
500 Fixes Savannah bug #16051.
502 * make.1: Remove extraneous "+".
503 Fixes Savannah bug #16652.
505 2006-09-06 Paul D. Smith <psmith@gnu.org>
507 * configure.in: Include sys/types.h when checking for sys/wait.h.
509 2006-08-18 Eli Zaretskii <eliz@gnu.org>
511 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
514 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.

526 <andreas.buening@nexgo.de>.
528 2006-04-30 Paul D. Smith <psmith@gnu.org>
530 * make.h: Include <direct.h> if HAVE_DIRECT_H.
531 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
533 2006-04-26 Paul D. Smith <psmith@gnu.org>
535 * README.cvs: Add a reminder to notify the GNU translation robot.
537 * doc/make.texi: Change @direcategory (requested by Karl Berry).
539 2006-04-20 Paul D. Smith <psmith@gnu.org>
541 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
542 that don't have extended grep.
543 (cvsclean): Use $(PERL) instead of perl.
545 2006-04-09 Paul D. Smith <psmith@gnu.org>

611 Declare and define sh_chars_sh[].
613 2006-03-23 Paul D. Smith <psmith@gnu.org>
615 * configure.in: Look for build.sh.in in $srcdir so it will be
616 built for remote configurations as well.
618 * Makefile.am: Make sure to clean up build.sh during distclean.
619 Fixes Savannah bug #16166.
621 * misc.c (log_access): Takes a const char *.

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

650 Patch from Joseph Myers <joseph@codesourcery.com>
652 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
654 * dep.h (struct dep): Add the stem field.
655 * misc.c (alloc_dep, free_dep): New functions.
656 (copy_dep_chain): Copy stem.
657 (free_dep_chain): Use free_dep.
658 * read.c (record_files): Store stem in the dependency line.
659 * file.c (expand_deps): Use stem stored in the dependency line. Use

667 2006-03-14 Paul D. Smith <psmith@gnu.org>
669 * expand.c (variable_append): Instead of appending everything then
670 expanding the result, we expand (or not, if it's simple) each part
672 (allocated_variable_append): Don't expand the final result.
673 Fixes Savannah bug #15913.
675 2006-03-09 Paul Smith <psmith@gnu.org>
677 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
678 listed non-existent files as changed. Turns out there's a bug in
679 the Linux kernel builds which means that this change causes
680 everything to rebuild every time. We will re-introduce this fix
681 in the next release, to give them time to fix their build system.
682 Fixes Savannah bug #16002.
683 Introduces Savannah bug #16051.
685 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
686 we *don't* find UNIX "/".

702 * commands.c (set_file_variables): Realloc, not malloc, the static
703 string values to avoid memory leaks.
705 * expand.c (recursively_expand_for_file): Only set reading_file to
706 an initialized value.
708 * implicit.c (pattern_search): We need to make a copy of the stem
709 if we get it from an intermediate dep, since those get freed.
711 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
713 (enter_file) [VMS]: Ditto.
714 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

720 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
721 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
722 the calls to _beginthreadex.
724 * expand.c (recursively_expand_for_file): Initialize `save' to
725 prevent compiler warnings.
727 2006-02-18 Eli Zaretskii <eliz@gnu.org>
729 * job.c (construct_command_argv_internal): Don't create a temporary
730 script/batch file if we are under -n. Call _setmode to switch the
731 script file stream to text mode.
733 2006-02-17 Paul D. Smith <psmith@gnu.org>
735 * variable.c (merge_variable_set_lists): Don't try to merge the
736 global_setlist. Not only is this useless, but it can lead to
737 circularities in the linked list, if global_setlist->next in one
738 list gets set to point to another list which also ends in
740 Fixes Savannah bug #15757.
742 2006-02-15 Paul D. Smith <psmith@gnu.org>
744 Fix for Savannah bug #106.
746 * expand.c (expanding_var): Keep track of which variable we're
747 expanding. If no variable is being expanded, it's the same as
749 * make.h (expanding_var): Declare it.
750 * expand.c (recursively_expand_for_file): Set expanding_var to the
751 current variable we're expanding, unless there's no file info in
752 it (could happen if it comes from the command line or a default
753 variable). Restore it before we exit.
754 * expand.c (variable_expand_string): Use the expanding_var file
755 info instead of the reading_file info.

761 (handle_function): Ditto.
763 2006-02-14 Paul D. Smith <psmith@gnu.org>
765 * read.c (eval): Even if the included filenames expands to the
766 empty string we still need to free the allocated buffer.
768 * implicit.c (pattern_search): If we allocated a variable set for
769 an impossible file, free it.
770 * variable.c (free_variable_set): New function.
771 * variable.h: Declare it.
773 * read.c (read_all_makefiles): Makefile names are kept in the
774 strcache, so there's never any need to alloc/free them.
777 * main.c (main): Add "archives" to the .FEATURES variable if
778 archive support is enabled.
779 * doc/make.texi (Special Variables): Document it.
781 2006-02-13 Paul D. Smith <psmith@gnu.org>
783 * implicit.c (pattern_search): Add checking for DOS pathnames to
784 the pattern rule target LASTSLASH manipulation.
785 Fixes Savannah bug #11183.

789 * (ALL FILES): Updated copyright and license notices.
791 2006-02-10 Paul D. Smith <psmith@gnu.org>
793 A new internal capability: the string cache is a read-only cache
794 of strings, with a hash table interface for fast lookup. Nothing
795 in the cache will ever be freed, so there's no need for reference
796 counting, etc. This is the beginning of a full solution for
797 Savannah bug #15182, but for now we only store makefile names here.
799 * strcache.c: New file. Implement a read-only string cache.
800 * make.h: Add prototypes for new functions.
801 * main.c (initialize_global_hash_tables): Initialize the string cache.
802 (print_data_base): Print string cache stats.
803 * read.c (eval_makefile): Use the string cache to store makefile

808 * dir.c (dir_contents_file_exists_p): Don't opendir if the
809 directory time stamp didn't change, except on FAT filesystems.
810 Suggested by J. David Bryan <jdbryan@acm.org>.
812 2006-02-09 Paul D. Smith <psmith@gnu.org>
814 * function.c (func_or): Implement a short-circuiting OR function.
815 (func_and): Implement a short-circuiting AND function.
816 (function_table_init): Update the table with the new functions.
817 * doc/make.texi (Conditional Functions): Changed the "if" section
818 to one on general conditional functions. Added documentation for
819 $(and ...) and $(or ...) functions.
820 * NEWS: Note new $(and ...) and $(or ...) functions.

829 2006-02-06 Paul D. Smith <psmith@gnu.org>
831 * vpath.c (selective_vpath_search): If the file we find has a
832 timestamp from -o or -W, use that instead of the real time.
833 * remake.c (f_mtime): If the mtime is a special token from -o or
834 -W, don't overwrite it with the real mtime.
835 Fixes Savannah bug #15341.

845 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
846 * README.cvs: Updates for building from CVS.
848 2006-02-05 Paul D. Smith <psmith@gnu.org>
850 * file.c (enter_file): Keep track of the last double_colon entry,
851 to avoid walking the list every time we want to add a new one.
852 Fixes Savannah bug #15533.
853 * filedef.h (struct file): Add a new LAST pointer.
855 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
856 the comparison. For 64-bits systems the result of the subtraction
857 might not fit into an int. Use comparison instead.
858 Fixes Savannah bug #15534.
860 * doc/make.texi: Update the chapter on writing commands to reflect

881 2006-01-21 Eli Zaretskii <eliz@gnu.org>
883 * remake.c (update_goal_chain): Set g->changed instead of
884 incrementing it, as it is only 8-bit wide, and could overflow if
885 many commands got started in update_file.
887 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
889 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

899 are already more children than sub_proc.c can handle, behave as if
900 the load were too high.
901 (start_job_command): Fix a typo in error message when process_easy
904 2006-01-14 Eli Zaretskii <eliz@gnu.org>

907 the shell is not sh.exe.
909 * job.c (create_batch_file): Renamed from create_batch_filename;
910 all callers changed. Don't close the temporary file; return its
911 file descriptor instead. New arg FD allows to return the file
913 (construct_command_argv_internal): Use _fdopen instead of fopen to

946 handling of backslash-newline sequences. Mention the differences
947 on MS-DOS and MS-Windows.
949 * NEWS: More details about building the MinGW port and a pointer
950 to README.W32. Fix the section name that describes the new
951 backward-incompatible processing of backslash-newline sequences.
952 The special processing of SHELL set to "cmd" is only relevant to
953 MS-Windows, not MS-DOS.
955 2005-12-17 Eli Zaretskii <eliz@gnu.org>
957 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
958 to DWORD, to avoid compiler warnings.

980 * make.1: Fix some display errors and document all existing options.
981 Patch provided by Mike Frysinger <vapier@gentoo.org>.
983 2005-12-11 Paul D. Smith <psmith@gnu.org>
985 * implicit.c (pattern_search): If 2nd expansion is not set for
986 this implicit rule, replace the pattern with the stem directly,
987 and don't re-expand the variable list. Along with the other
988 .SECONDEXPANSION changes below, fixes bug #13781.
990 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
992 * implicit.c (pattern_search): Mark other files that this rule
993 builds as targets so that they are not treated as intermediates

1019 * maintMakefile: We only need to build the templates when we are
1020 creating a distribution, so don't do it for "all".
1022 2005-10-24 Paul D. Smith <psmith@gnu.org>
1024 Make secondary expansion optional: its enabled by declaring the
1025 special target .SECONDEXPANSION.

1050 Set the staticpattern field for prereqs of static pattern targets.
1052 2005-10-16 Paul D. Smith <psmith@gnu.org>
1054 * main.c (main): Set CURDIR to be a file variable instead of a
1055 default, so that values of CURDIR inherited from the environment
1056 won't override the make value.
1058 2005-09-26 Paul D. Smith <psmith@gnu.org>
1060 * job.c (construct_command_argv_internal): If the line is empty

1072 * function.c (func_error): On Windows, output from $(info ...)
1073 seems to come in the wrong order. Try to force it with fflush().
1075 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1077 * read.c (record_files): Move code that sets stem for static
1078 pattern rules out of the if (!two_colon) condition so it is
1079 also executed for two-colon rules. Fixes Savannah bug #13881.
1081 2005-08-08 Paul D. Smith <psmith@gnu.org>
1083 * make.h: Don't test that __STDC__ is non-0. Some compilers
1084 (Windows for example) set it to 0 to denote "ISO C + extensions".
1087 2005-08-07 Paul D. Smith <psmith@gnu.org>
1089 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1090 conditional (slightly different version of a fix from Eli).
1092 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1093 If make is running in parallel without -k and two jobs die in a
1094 row, but not too close to each other, then make will quit without
1095 waiting for the rest of the jobs to die.
1097 * main.c (die): Don't reset err before calling reap_children() the
1098 second time: we still want it to be in the error condition.
1099 * job.c (reap_children): Use a static variable, rather than err,
1100 to control whether or not the error message should be printed.
1102 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1104 * w32/subproc/sub_proc.c: Include signal.h.
1105 (process_pipe_io, process_file_io): Pass a pointer to a local
1106 DWORD variable to GetExitCodeProcess. If the exit code is
1107 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1109 * job.c [WINDOWS32]: Include windows.h.
1110 (main_thread) [WINDOWS32]: New global variable.
1111 (reap_children) [WINDOWS32]: Get the handle for the main thread
1112 and store it in main_thread.
1114 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1115 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1116 doing anything else. When we are done, close the main thread
1117 handle and exit with status 130.
1119 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1121 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1124 * main.c (find_and_set_default_shell): If found a DOSish shell,
1125 set sh_found and the value of default_shell, and report the
1126 findings in debug mode.
1128 * job.c (construct_command_argv_internal): Check unixy_shell, not
1129 no_default_sh_exe, to decide whether to use Unixy or DOSish
1132 * README.W32: Update with info about the MinGW build.
1134 * build_w32.bat: Support MinGW.
1136 * w32/subproc/build.bat: Likewise.
1138 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1139 printing DWORD args.
1141 * function.c (windows32_openpipe): Fix format strings for printing
1144 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1146 (start_job_command): Fix format string for printing the result of
1148 (start_job_command) [WINDOWS32]: Do not define.
1149 (exec_command): Fix format string for printing HANDLE args.
1151 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1152 to avoid compiler warnings.
1153 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1154 (Note: some of these fixes were submitted independently by J. Grant)
1156 2005-07-30 J. Grant <jg@jguk.org>
1158 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1159 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1160 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1162 2005-07-15 Paul Smith <psmith@gnu.org>
1164 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1165 we don't have a POSIX shell, then revert to the old
1166 backslash-newline behavior (where they are stripped).
1169 2005-07-08 Paul D. Smith <psmith@gnu.org>
1171 * config.h.W32.template: Reorder to match the standard config.h,
1172 for easier comparisons.
1173 From J. Grant <jg@jguk.org>
1175 * maintMakefile: Remove .dep_segment before overwriting it, in
1176 case it's not writable or noclobber is set.
1177 * expand.c (variable_expand_string): Cast result of pointer
1178 arithmetic to avoid a warning.
1179 * main.c (switches): Add full-fledged final initializer.
1181 2005-07-06 Paul D. Smith <psmith@gnu.org>
1183 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1184 * signame.c (strsignal): If we found _sys_siglist[] or
1185 __sys_siglist[] use those instead of sys_siglist[].
1186 From Albert Chin <china@thewrittenword.com>
1188 2005-07-04 Paul D. Smith <psmith@gnu.org>
1190 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1191 globfree(); set up to use the GNU versions.
1192 From Martin Zinser <zinser@zinser.no-ip.info>
1194 2005-07-03 Paul D. Smith <psmith@gnu.org>
1196 From J. Grant <jg@jguk.org>:
1198 * README.W32.template: Update the Windows and tested MSVC versions.
1199 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1200 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1201 * build_w32.bat: Ditto.
1202 * w32/subproc/build.bat: Ditto.
1204 2005-06-28 Paul D. Smith <psmith@gnu.org>
1206 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1207 declaration was checked but not present.
1209 2005-06-27 Paul D. Smith <psmith@gnu.org>
1211 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1212 to unsigned long. Fixes Savannah bug #13550.
1214 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1215 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1216 Fixes Savannah bug #13551.
1218 2005-06-26 Paul D. Smith <psmith@gnu.org>
1220 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1221 it if ANSI_STRING is not set.
1223 2005-06-25 Paul D. Smith <psmith@gnu.org>
1225 * read.c (eval): If no filenames are passed to any of the
1226 "include" variants, don't print an error.
1227 * doc/make.texi (Include): Document this.
1228 Fixes Savannah bug #1761.
1230 * job.c (construct_command_argv_internal): Sanitize handling of
1231 backslash/newline pairs according to POSIX: that is, keep the
1232 backslash-newline in the command script, but remove a following
1233 TAB character, if present. In the fast path, make sure that the
1234 behavior matches what the shell would do both inside and outside
1235 of quotes. In the slow path, quote the backslash and put a
1236 literal newline in the string.
1237 Fixes Savannah bug #1332.
1238 * doc/make.texi (Execution): Document the new behavior and give
1240 * NEWS: Make a note of the new behavior.
1242 * make.h [WINDOWS32]: #include <direct.h>.
1243 Fixes Savannah bug #13478.
1245 * remake.c (name_mtime): If the stat() of a file fails and the -L
1246 option was given and the file is a symlink, take the best mtime of
1247 the symlink we can get as the mtime of the file and don't fail.
1248 Fixes Savannah bug #13280.
1250 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1251 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1252 inside a variable reference. Make this function static as it's
1254 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1255 parsing an unexpanded line looking for semicolons.
1256 Fixes Savannah bug #1454.
1257 * misc.c (remove_comments): Move this to read.c and make it static
1258 as it's only used there. Call find_char_unquote() with new arg.
1259 * make.h: Remove prototypes for find_char_unquote() and
1260 remove_comments() since they're static now.
1262 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1263 its export flag and obtain its value. When we need to re-exec,
1264 increment the value and add it into the environment.
1265 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1266 * NEWS: Mention MAKE_RESTARTS.
1267 * main.c (always_make_set): New variable. Change the -B option to
1268 set this one instead.
1269 (main): When checking makefiles, only set always_make_flag if
1270 always_make_set is set AND the restarts flag is 0. When building
1271 normal targets, set it IFF always_make_set is set.
1272 (main): Avoid infinite recursion with -W, too: only set what-if
1273 files to NEW before we check makefiles if we've never restarted
1274 before. If we have restarted, set what-if files to NEW _after_ we
1276 Fixes Savannah bug #7566:
1278 2005-06-17 Paul D. Smith <psmith@gnu.org>
1280 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1281 in the prerequisites list.
1283 2005-06-12 Paul D. Smith <psmith@gnu.org>
1285 Fix Savannah bug # 1328.
1287 * configure.in: Check for atexit().
1288 * misc.c (close_stdout): Test stdout to see if writes to it have
1289 failed. If so, be sure to exit with a non-0 error code. Based on
1290 code found in gnulib.
1291 * make.h: Prototype.
1292 * main.c (main): Install close_stdout() with atexit().
1294 2005-06-10 Paul D. Smith <psmith@gnu.org>
1296 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1298 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1299 headers; make vmsWaitForChildren() static; extern vmsify().
1300 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1301 Don't create child_execute_job() here (it's in vmsjobs.c).
1302 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1304 2005-06-09 Paul D. Smith <psmith@gnu.org>
1306 * variable.c (push_new_variable_scope): File variables point
1307 directly to the global_setlist variable. So, inserting a new
1308 scope in front of that has no effect on those variables: they
1309 don't go through current_variable_set_list. If we're pushing a
1310 scope and the current scope is global, push it "the other way" so
1311 that the new setlist is in the global_setlist variable, and
1312 next points to a new setlist with the global variable set.
1313 (pop_variable_scope): Properly undo a push with the new
1315 Fixes Savannah bug #11913.
1317 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1319 * job.c (reap_children): Don't die of the command failed but
1320 the dontcare flag is set. Fixes Savannah bug #13216.
1322 * implicit.c (pattern_search): When creating a target from
1323 an implicit rule match, lookup pattern target and set precious
1324 flag in a newly created target. Fixes Savannah bug #13218.
1326 2005-05-13 Paul D. Smith <psmith@gnu.org>
1328 Implement "if... else if... endif" syntax.
1330 * read.c (eval): Push all checks for conditional words ("ifeq",
1331 "else", etc.) down into the conditional_line() function.
1332 (conditional_line): Rework to allow "else if..." clause. New
1333 return value -2 for lines which are not conditionals. The
1334 ignoring flag can now also be 2, which means "already parsed a
1335 true branch". If that value is seen no other branch of this
1336 conditional can be considered true. In the else parsing if there
1337 is extra text after the else, invoke conditional_line()
1338 recursively to see if it's another conditional. If not, it's an
1339 error. If so, raise the conditional value to this level instead
1340 of creating a new conditional nesting level. Special check for
1341 "else" and "endif", which aren't allowed on the "else" line.
1342 * doc/make.texi (Conditional Syntax): Document the new syntax.
1344 2005-05-09 Paul D. Smith <psmith@gnu.org>
1346 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1347 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1348 recurses to the w32 directory, even on non-Windows systems. Use
1349 the method suggested in the automake manual.
1350 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1351 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1353 2005-05-07 Paul D. Smith <psmith@gnu.org>
1355 * main.c (die): If we're dying with a fatal error (not that a
1356 command has failed), write back any leftover tokens before we go.
1358 * job.c (set_child_handler_action_flags): If there are jobs
1359 waiting for the load to go down, set an alarm to go off in 1
1360 second. This allows us to wake up from a potentially long-lasting
1361 read() and start a new job if the load has gone down. Turn it off
1363 (job_noop): Dummy signal handler function.
1364 (new_job): Invoke it with the new semantics.
1366 * docs/make.texi: Document secondary expansion. Various cleanups
1369 2005-05-03 Paul D. Smith <psmith@gnu.org>
1371 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1372 the targets which are to ultimately be made are called "goals";
1373 see the GNU make manual. Also, MAKECMDGOALS, etc.
1375 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1376 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1377 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1379 2005-05-02 Paul D. Smith <psmith@gnu.org>
1381 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1382 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1383 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1384 functions to vmsjobs.c. #include it into jobs.c.
1386 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1387 jobserver tokens. I found that this happens when an exported
1388 recursive variable contains a $(shell ...) function reference: in
1389 this situation we could "forget" to write back a token.
1391 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1392 we have. It's not reliable to depend on the number of children in
1393 our linked list so keep a separate count.
1394 (new_job): Check jobserver_tokens rather than children &&
1395 waiting_jobs. Increment jobserver_tokens when we get one.
1396 (free_child): If jobserver_tokens is 0, internal error. If it's
1397 >1, write a token back to the jobserver pipe (we don't write a
1398 token for the "free" job). Decrement jobserver_tokens.
1400 * main.c: Add variable master_job_slots.
1401 (main): Set it to hold the number of jobs requested if we're the
1402 master process, when using the jobserver.
1403 (die): Sanity checks: first test jobserver_tokens to make sure
1404 this process isn't holding any tokens we didn't write back.
1405 Second, if master_job_slots is set count the tokens left in the
1406 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1408 2005-04-24 Paul D. Smith <psmith@gnu.org>
1410 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1411 with -l# can lose jobserver tokens, because waiting jobs are not
1412 consulted properly when checking for the "free" token.
1414 * job.c (free_child): Count waiting_jobs as having tokens.
1415 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1416 handle jobs waiting for the load to drop.
1418 2005-04-23 Paul D. Smith <psmith@gnu.org>
1420 * main.c (main): Be careful to not core if a variable setting in
1421 the environment doesn't contain an '='. This is illegal but can
1422 happen in broken setups.
1423 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1425 2005-04-12 Paul D. Smith <psmith@gnu.org>
1427 The second expansion feature causes significant slowdown. Timing
1428 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1429 read the makefile before the feature, to 11+s to do the same
1430 operations after the feature. Additionally, memory usage
1431 increased drastically. To fix this I added some intelligence that
1432 avoids the overhead of the second expansion unless it's required.
1434 * dep.h: Add a new boolean field, need_2nd_expansion.
1436 * read.c (eval): When creating the struct dep for the target,
1437 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1438 (record_files): If there's a "%" in a static pattern rule, it gets
1439 converted to "$*" so set need_2nd_expansion to 1.
1441 * file.c (expand_deps): Rework to be more efficient. Only perform
1442 initialize_file_variables(), set_file_variables(), and
1443 variable_expand_for_file() if the need_2nd_expansion is set.
1445 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1446 (pattern_search): Ditto.
1447 * main.c (handle_non_switch_argument): Ditto.
1449 * read.c (read_all_makefiles): Ditto.
1450 (eval_makefile): Ditto.
1452 2005-04-07 Paul D. Smith <psmith@gnu.org>
1454 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1455 * variable.c (sync_Path_environment): Ditto.
1456 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1458 * main.c (main): Define the .FEATURES variable.
1459 * NEWS: Announce .FEATURES.
1460 * doc/make.texi (Special Variables): Document .FEATURES.
1462 * remake.c (check_dep): If a file is .PHONY, update it even if
1463 it's marked intermediate. Fixes Savannah bug #12331.
1465 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1467 * file.c (expand_deps): Factor out the second expansion and
1468 prerequisite line parsing logic from snap_deps().
1470 * file.c (snap_deps): Use expand_deps(). Expand and parse
1471 prerequisites of the .SUFFIXES special target first. Fixes
1472 Savannah bug #12320.
1474 2005-03-13 Paul D. Smith <psmith@gnu.org>
1476 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1479 2005-03-11 Paul D. Smith <psmith@gnu.org>
1481 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1482 available, not undefined (from Earnie Boyd).
1484 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1486 * implicit.c (pattern_search): Mark an intermediate target as
1487 precious if it happened to be a prerequisite of some (other)
1488 target. Fixes Savannah bug #12267.
1490 2005-03-09 Paul D. Smith <psmith@gnu.org>
1492 * read.c (eval_makefile): Add alloca(0).
1493 (eval_buffer): Ditto.
1495 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1497 * main.c (main): Use o_file instead of o_default when defining
1498 the .DEFAULT_TARGET special variable.
1499 * read.c (eval): Use define_variable_global() instead of
1500 define_variable() when setting new value for the .DEFAULT_TARGET
1501 special variable. Fixes Savannah bug #12266.
1503 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1505 * imlicit.c (pattern_search): Mark files for which an implicit
1506 rule has been found as targets. Fixes Savannah bug #12202.
1508 2005-03-04 Paul D. Smith <psmith@gnu.org>
1511 * doc/make.texi (Automatic Variables): Document $|.
1513 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1515 * read.c (record_files): Instead of substituting % with
1516 actual stem value in dependency list replace it with $*.
1517 This fixes stem triple expansion bug.
1519 * implicit.c (pattern_search): Copy stem to a separate
1520 buffer and make it a properly terminated string. Assign
1521 this buffer instead of STEM (which is not terminated) to
1522 f->stem. Instead of substituting % with actual stem value
1523 in dependency list replace it with $*. This fixes stem
1524 triple expansion bug.
1526 2005-03-01 Paul D. Smith <psmith@gnu.org>
1528 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1529 on Windows, as it takes a handle not a pid. Just exit.
1530 Fix from patch #3679, provided by Alessandro Vesely.
1532 * configure.in: Update check for sys_siglist[] from autoconf manual.
1533 * signame.c (strsignal): Update to use the new autoconf macro.
1535 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1537 * read.c (record_files): Add a check for the list of prerequisites
1538 of a static pattern rule being empty. Fixes Savannah bug #12180.
1540 2005-02-28 Paul D. Smith <psmith@gnu.org>
1542 * doc/make.texi (Text Functions): Update docs to allow the end
1543 ordinal for $(wordlist ...) to be 0.
1544 * function.c (func_wordlist): Fail if the start ordinal for
1545 $(wordlist ...) is <1. Matches documentation.
1546 Resolves Savannah support request #103195.
1548 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1549 previously we were stopping when !-q, exactly the opposite. This
1550 has been wrong since version 1.34, in 1994!
1551 (update_file): If we got an error don't break out to run more
1552 double-colon rules: just return immediately.
1553 Fixes Savannah bug #7144.
1555 2005-02-27 Paul D. Smith <psmith@gnu.org>
1557 * misc.c (end_of_token): Make argument const.
1558 * make.h: Update prototype.
1560 * function.c (abspath, func_realpath, func_abspath): Use
1561 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1562 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1563 * read.c (record_files): Ditto.
1564 * variable.c (do_variable_definition): Ditto.
1566 * function.c (func_error): Create a new function $(info ...) that
1567 simply prints the message to stdout with no extras.
1568 (function_table_init): Add new function to the table.
1569 * NEWS: Add $(info ...) reference.
1570 * doc/make.texi (Make Control Functions): Document it.
1572 New feature: if the system supports symbolic links, and the user
1573 provides the -L/--check-symlink-time flag, then use the latest
1574 mtime between the symlink(s) and the target file.
1576 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1577 readlink(). If both are available, define MAKE_SYMLINKS.
1578 * main.c: New variable: check_symlink_flag.
1579 (usage): Add a line for -L/--check-symlink-times to the help string.
1580 (switches): Add -L/--check-symlink-times command line argument.
1581 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1582 print a warning and disable it again.
1583 * make.h: Declare check_symlink_flag.
1584 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1585 if the file is a symlink then check each link in the chain and
1586 choose the NEWEST mtime we find as the mtime for the file. The
1587 newest mtime might be the file itself!
1588 * NEWS: Add information about this new feature.
1589 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1591 Avoid core dumps described in Savannah bug # 12124:
1593 * file.c: New variable snapped_deps remember whether we've run
1595 (snap_deps): Set it.
1596 * filedef.h: Extern it.
1597 * read.c (record_files): Check snapped_deps; if it's set then
1598 we're trying to eval a new target/prerequisite relationship from
1599 within a command script, which we don't support. Fatal.
1601 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1603 Implementation of the .DEFAULT_TARGET special variable.
1605 * read.c (eval): If necessary, update default_target_name when
1607 * read.c (record_files): Update default_target_file if
1608 default_target_name has changed.
1609 * main.c (default_target_name): Define.
1610 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1611 default_target_name is set use default_target_file as a root
1613 * filedef.h (default_target_name): Declare.
1614 * dep.h (free_dep_chain):
1615 * misc.c (free_dep_chain): Change to operate on struct nameseq
1616 and change name to free_ns_chain.
1617 * file.c (snap_deps): Update to use free_ns_chain.
1619 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1621 Implementation of the second expansion in explicit rules,
1622 static pattern rules and implicit rules.
1624 * read.c (eval): Refrain from chopping up rule's dependencies.
1625 Store them in a struct dep as a single dependency line. Remove
1626 the code that implements SySV-style automatic variables.
1628 * read.c (record_files): Adjust the code that handles static
1629 pattern rules to expand all percents instead of only the first
1630 one. Reverse the order in which dependencies are stored so that
1631 when the second expansion reverses them again they appear in
1632 the makefile order (with some exceptions, see comments in
1633 the code). Remove the code that implements SySV-style automatic
1636 * file.c (snap_deps): Implement the second expansion and chopping
1637 of dependency lines for explicit rules.
1639 * implicit.c (struct idep): Define an auxiliary data type to hold
1640 implicit rule's dependencies after stem substitution and
1643 * implicit.c (free_idep_chain): Implement.
1645 * implicit.c (get_next_word): Implement helper function for
1646 parsing implicit rule's dependency lines into words taking
1647 into account variable expansion requests. Used in the stem
1650 * implicit.c (pattern_search): Implement the second expansion
1651 for implicit rules. Also fixes bug #12091.
1653 * commands.h (set_file_variables): Declare.
1654 * commands.c (set_file_variables): Remove static specifier.
1656 * dep.h (free_dep_chain): Declare.
1657 * misc.c (free_dep_chain): Implement.
1659 * variable.h (variable_expand_for_file): Declare.
1660 * expand.c (variable_expand_for_file): Remove static specifier.
1662 * make.h (strip_whitespace): Declare.
1663 * function.c (strip_whitespace): Remove static specifier.
1665 2005-02-26 Paul D. Smith <psmith@gnu.org>
1667 * main.c (main): Check for ferror() when reading makefiles from stdin.
1668 Apparently some shells in Windows don't close pipes properly and
1671 2005-02-24 Jonathan Grant <jg@jguk.org>
1673 * configure.in: Add MinGW configuration options, and extra w32 code
1675 * Makefile.am: Add MinGW configuration options, and extra w32 code
1677 * main.c: Determine correct program string (after last \ without .exe).
1678 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1680 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1681 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1682 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1683 environment support.
1685 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1687 * function.c (func_shell): When initializing error_prefix, check
1688 that reading file name is not null. This fixes long-standing
1689 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1691 2005-02-09 Paul D. Smith <psmith@gnu.org>
1693 * maintMakefile: Update the CVS download URL to simplify them.
1694 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1695 downloading the .texi files from Savannah now.
1697 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1699 * main.c (handle_non_switch_argument): Only add variables to
1700 command_variables if they're not already there: duplicate settings
1701 waste space and can be confusing to read.
1703 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1704 this header is never included by non-WINDOWS32 code, and it
1705 requires <config.h> to define which isn't always included first.
1707 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1708 testing MINGW32 versions.
1710 * main.c (log_working_directory): flush stdout to be sure the WD
1711 change is printed before any stderr messages show up.
1713 2005-02-01 Paul D. Smith <psmith@gnu.org>
1715 * maintMakefile (po_repo): Update the GNU translation site URL.
1717 2004-12-01 Paul D. Smith <psmith@gnu.org>
1719 * main.c (main): Change char* env_shell to struct variable shell_var.
1720 * variable.c (target_environment): Use new shell_var.
1722 2004-11-30 Paul D. Smith <psmith@gnu.org>
1724 * configure.in: The old way we avoided creating build.sh from
1725 build.sh.in before build.sh.in exists doesn't work anymore; we
1726 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1727 the help!). This also keeps automake from complaining.
1728 * Makefile.am (README): Add a dummy target so automake won't
1729 complain that this file doesn't exist when we checkout from CVS.
1730 * maintMakefile (.dep_segment): Rewrite this rule since newer
1731 versions of automake don't provide DEP_FILES.
1733 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1735 Implementation of `realpath' and `abspath' built-in functions.
1737 * configure.in: Check for realpath.
1738 * function.c (abspath): Return an absolute file name that does
1739 not contain any `.' or `..' components, nor repeated `/'.
1740 * function.c (func_abspath): For each name call abspath.
1741 * function.c (func_realpath): For each name call realpath
1742 from libc or delegate to abspath if realpath is not available.
1743 * doc/make.texi (Functions for File Names): Document new functions.
1744 * doc/make.texi (Quick Reference): Ditto.
1746 2004-11-28 Paul D. Smith <psmith@gnu.org>
1748 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1749 arguments. Fixes bug #10252.
1751 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1753 * main.c (main): Set SHELL to v_noexport by default. Remember the
1754 original environment setting of SHELL in the env_shell variable.
1755 * main.h: Export new env_shell variable.
1756 * variable.c (target_environment): If we find a v_noexport
1757 variable for SHELL, add a SHELL variable with the env_shell value.
1758 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1759 * doc/make.texi (Variables/Recursion): Ditto.
1761 2004-11-28 Paul D. Smith <psmith@gnu.org>
1763 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1764 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1765 Patch by Alessandro Vesely.
1767 2004-11-12 Paul D. Smith <psmith@gnu.org>
1769 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1770 the command line if it's inside a string.
1771 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1773 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1775 * function.c (func_lastword): New function: return last word
1776 from the list of words.
1777 * doc/make.texi: Document $(lastword ). Fix broken links in
1778 Quick Reference section.
1780 2004-10-06 Paul D. Smith <psmith@gnu.org>
1782 Apply patch from Alessandro Vesely, provided with bug # 9748.
1783 Fix use of tmpnam() to work with Borland C.
1785 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1786 construction of a temporary filename, and call new function
1787 create_batch_filename().
1788 (create_batch_filename) [WINDOWS32]: New function to create a
1791 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1793 * read.c (record_target_var): Expand simple pattern-specific
1795 * variable.c (initialize_file_variables): Do not expand simple
1796 pattern-specific variable.
1798 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1800 * remake.c (update_file_1): When rebuilding makefiles inherit
1801 dontcare flag from a target that triggered update.
1803 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1805 * variable.c (initialize_file_variables): Mark pattern-specific
1806 variable as a per-target and copy export status.
1808 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1810 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1812 * implicit.c (pattern_search): When considering an implicit rule's
1813 prerequisite check that it is actually a target rather then
1814 just an entry in the file hashtable.
1816 2004-09-21 Paul D. Smith <psmith@gnu.org>
1818 * read.c (readstring): Fix some logic errors in backslash handling.
1819 (eval): Remove some unnecessary processing in buffer handling.
1820 (record_target_var): Assert that parse_variable_definition() succeeded.
1821 Reported by: Markus Mauhart <qwe123@chello.at>.
1823 * misc.c: Removed the sindex() function. All instances of this
1824 function were trivially replaceable by the standard strstr()
1825 function, and that function will always have better (or certainly
1826 no worse) performance than the very simple-minded algorithm
1827 sindex() used. This can matter with complex makefiles.
1828 * make.h: Remove the prototype for sindex().
1829 * function.c (subst_expand): Convert sindex() call to strstr().
1830 This means we no longer need to track the TLEN value so remove that.
1831 (func_findstring): Convert sindex() to strstr().
1832 * commands.c (chop_commands): Convert sindex() calls to strstr().
1833 Suggested by: Markus Mauhart <qwe123@chello.at>.
1835 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1836 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1837 If SHELL is set to CMD.EXE then assume it's batch-mode and
1838 non-unixy. I wrote the code differently from the patch, though,
1839 to make it safer. This also resolves bug #9174.
1841 2004-09-20 Paul D. Smith <psmith@gnu.org>
1843 * expand.c (variable_expand_string): Modify to invoke
1844 patsubst_expand() instead of subst_expand(); the latter didn't
1845 handle suffix patterns correctly.
1846 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1847 was used only from variable_expand_string() and is no longer used
1849 (func_subst): Ditto, on call to subst_expand().
1850 (patsubst_expand): Require the percent pointers to point to the
1851 character after the %, not to the % itself.
1852 * read.c (record_files): New call criteria for patsubst_expand().
1853 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1854 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1856 2004-09-19 Paul D. Smith <psmith@gnu.org>
1858 * function.c (subst_expand): Fix a check in by_word: look for a
1859 previous blank if we're beyond the beginning of the string, not
1860 the beginning of the word.
1861 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1863 2004-05-16 Paul D. Smith <psmith@gnu.org>
1865 * remake.c (update_goal_chain): Change the argument specifying
1866 whether we're rebuilding makefiles to be a global variable,
1867 REBUILDING_MAKEFILES.
1868 (complain): Extract the code that complains about no rules to make
1869 a target into a separate function.
1870 (update_file_1): If we tried to rebuild a file during the makefile
1871 rebuild phase and it was dontcare, then no message was printed.
1872 If we then try to build the same file during the normal build,
1873 print a message this time.
1874 (remake_file): Don't complain about un-remake-able files when
1875 we're rebuilding makefiles.
1877 2004-05-11 Paul D. Smith <psmith@gnu.org>
1879 * job.c (construct_command_argv_internal): OS/2 patches from
1880 Andreas Buening <andreas.buening@nexgo.de>.
1882 2004-05-10 Paul D. Smith <psmith@gnu.org>
1884 * remake.c (update_file): Don't walk the double-colon chain unless
1885 this is a double-colon rule. Fix suggested by Boris Kolpackov
1886 <boris@kolpackov.net>.
1888 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1889 * readme.vms: New section describing OpenVMS support and issues.
1890 * default.c (default_variables): Add support for IA64.
1891 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1892 without some privilege aborts make with the error
1893 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1894 pressing Ctrl+Y and the input device is no terminal. The change
1895 catches this error and just continues.
1897 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1899 2004-04-25 Paul D. Smith <psmith@gnu.org>
1901 * commands.c (set_file_variables): Set $< properly in the face of
1902 order-only prerequisites.
1903 Patch from Boris Kolpackov <boris@kolpackov.net>
1905 2004-04-21 Bob Byrnes <byrnes@curl.com>
1907 * main.c (main): Notice failures to remake makefiles.
1909 2004-03-28 Paul D. Smith <psmith@gnu.org>
1911 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1913 * job.c: No default shell for RISC OS.
1914 (load_too_high): Hard-code the return to 1.
1915 (construct_command_argv_internal): No sh_chars or sh_cmds.
1916 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1918 2004-03-20 Paul D. Smith <psmith@gnu.org>
1920 * variable.c (do_variable_definition): Don't append from the
1921 global set if a previous non-appending target-specific variable
1922 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1925 * expand.c (reference_variable): Don't give up on variables with
1926 no value that have the target-specific append flag set: they might
1927 have a value after all. Reported by Oliver Schmidt
1928 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1929 <nikulin@dx1cmd.inp.nsk.su>.
1931 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1932 refer to absolute pathnames in directories that don't exist: some
1933 portion of the makefile could create those directories before we
1934 match the pattern. Fixes bugs #775 and #108.
1936 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1938 * main.c (main): Free makefile_mtimes if we have any.
1939 * README.W32.template: Update documentation for the current status
1940 of the MS-Windows port.
1941 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1942 environment variable is sometimes already defined which causes the
1944 * main.c (debug_signal_handler): Only define this function if
1945 SIGUSR1 is available.
1947 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1949 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1950 * README.OS2.template: Documentation updates.
1951 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1952 link line for safety.
1953 * maintMakefile (build.sh.in): Remove an extraneous ")".
1954 * job.c (child_execute_job): Close saved FDs.
1955 * job.c (exec_command) [OS/2]: exec_command(): If the command
1956 can't be exec'ed and if the shell is not Unix-sh, then try again
1957 with argv = { "cmd", "/c", ... }. Normally, this code is never
1958 reached for the cmd shell unless the command really doesn't exist.
1959 (construct_command_argv_internal) [OS/2]: The code for cmd
1960 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1961 The CMD builtin commands are case insensitive so use strcasecmp().
1963 2004-03-19 Paul D. Smith <psmith@gnu.org>
1965 * read.c (do_define): Re-order line counter increment so the count
1966 is accurate (we were losing one line per define). Reported by
1967 Dave Yost <Dave@Yost.com>.
1969 2004-03-06 Paul D. Smith <psmith@gnu.org>
1971 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1973 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1974 * misc.c (message,error,fatal): Ditto.
1975 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1976 * config.h.W32.template: Ditto.
1977 * config.h-vms.template: Ditto.
1978 * config.ami.template: Ditto.
1980 2004-03-04 Paul D. Smith <psmith@gnu.org>
1982 * README.template: Add a note about broken /bin/sh on SunOS
1983 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1985 * misc.c (message, error, fatal): Don't use "..." if we're using
1986 varargs. ansi2knr should handle this but it doesn't work: it
1987 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1988 done. On many systems (SunOS for example) va_dcl is a #define.
1989 So, force the use of the non-"..." version on pre-ANSI compilers.
1991 * maintMakefile (sign-dist): Create some rules to help automate
1992 the new GNU ftp upload method.
1994 2004-02-24 Paul D. Smith <psmith@gnu.org>
1996 * config.h.W32.template: Add HAVE_STDARG_H
1997 * config.h-vms.template: Ditto.
1998 * config.ami.template: Ditto.
2000 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2002 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2003 * build_w32.bat: Remove extra "+".
2005 2004-02-23 Paul D. Smith <psmith@gnu.org>
2007 * make.h: Create an UNUSED macro to mark unused parameters.
2008 * (many): Clean up warnings by applying UNUSED, fixing
2009 signed/unsigned incompatibilities, etc.
2011 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2013 * filedef.h: Name the command_state enumeration.
2014 * file.c (set_command_state): Use the enumeration in the function
2017 * configure.in: Explicitly set SET_MAKE to empty, to disable
2018 MAKE=make even when no make already exists. Fix bug #3823.
2020 2004-02-22 Paul D. Smith <psmith@gnu.org>
2022 * maintMakefile: Perl script to clean up all non-CVS files. Use
2023 it on all the subdirectories for the cvs-clean target.
2025 * main.c (decode_switches): Require non-empty strings for all our
2026 string command-line options. Fixes Debian bug # 164165.
2028 * configure.in: Check for stdarg.h and varargs.h.
2029 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2030 for printing messages.
2031 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2036 A number of patches for OS/2 support from Andreas Buening
2037 <andreas.buening@nexgo.de>:
2039 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2040 disable the SIGCHLD handler.
2041 (reap_children) [OS/2]: Remove special handling of job_rfd.
2042 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2043 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2044 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2045 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2046 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2049 2004-02-21 Paul D. Smith <psmith@gnu.org>
2051 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2052 <mail@kristov.de> reports that if process_begin() fails we don't
2053 handle the error condition correctly in all cases.
2054 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2055 to have a newline on the message.
2057 * job.c (construct_command_argv_internal): Add "test" to UNIX
2058 sh_cmds[]. Fixes Savannah bug # 7606.
2060 2004-02-04 Paul D. Smith <psmith@gnu.org>
2062 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2063 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2064 Hartmut Becker <Hartmut.Becker@hp.com>.
2066 2004-01-21 Paul D. Smith <psmith@gnu.org>
2068 * job.c (load_too_high): Implement an algorithm to control the
2069 "thundering herd" problem when using -l to control job creation
2070 via the load average. The system only recomputes the load once a
2071 second but we can start many jobs in a second. To solve this we
2072 keep track of the number of jobs started in the last second and
2073 apply a weight to try to guess what a correct load would be.
2074 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2075 Also fixes bug #4693.
2076 (reap_children): Decrease the job count for this second.
2077 (start_job_command): Increase the job count for this second.
2079 * read.c (conditional_line): Expand the text after ifn?def before
2080 checking to see if it's a single word. Fixes bug #7257.
2082 2004-01-09 Paul D. Smith <psmith@gnu.org>
2084 * file.c (print_file): Recurse to print all targets in
2085 double-colon rules. Fixes bug #4518, reported (with patch) by
2086 Andrew Chatham <chatham@google.com>.
2088 2004-01-07 Paul D. Smith <psmith@gnu.org>
2090 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2091 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2092 AC_FUNC_SETVBUF_REVERSED.
2094 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2095 (MAKE Variable): Fix Savannah bug #4898.
2097 * job.c (construct_command_argv_internal): Add "!" to the list of
2098 shell escape chars. POSIX sh allows it to appear before a
2099 command, to negate the exit code. Fixes bug #6404.
2101 * implicit.c (pattern_search): When matching an implicit rule,
2102 remember which dependencies have the ignore_mtime flag set.
2103 Original fix provided in Savannah patch #2349, by Benoit
2104 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2106 2003-11-22 Paul D. Smith <psmith@gnu.org>
2108 * README.W32.template (Outputs): Clarification on -j with
2109 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2112 2003-11-02 Paul D. Smith <psmith@gnu.org>
2114 * function.c (func_if): Strip all the trailing whitespace from the
2115 condition, then don't expand it. Fixed bug # 5798.
2117 * expand.c (recursively_expand_for_file): If we're expanding a
2118 variable with no file context, then use the variable's context.
2121 2003-10-21 Paul D. Smith <psmith@gnu.org>
2123 * main.c (log_working_directory): Add newlines to printf()s.
2125 * README.cvs: Add a note to ignore warnings during autoreconf.
2127 * maintMakefile (po_repo): Set a new URL for PO file updates.
2128 (get-config/config.guess get-config/config.sub): Get these files
2129 from the Savannah config project instead of ftp.gnu.org.
2131 2003-10-05 Paul Eggert <eggert@twinsun.com>
2133 * main.c (main): Avoid potential subscript error if environ has
2136 2003-08-22 Paul D. Smith <psmith@gnu.org>
2138 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2139 systems which don't yet implement the C89 standard :-/.
2141 2003-07-18 Paul D. Smith <psmith@gnu.org>
2143 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2144 [WINDOWS32]: Initialize hash.
2146 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2148 * dir.c (read_dirstream): Provide a workaround for broken versions of
2149 the MinGW dirent structure.
2151 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2153 * w32/include/dirent.h: Add __MINGW32__ filter.
2155 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2157 * make.h: Add global declaration of *make_host.
2158 * main.c (print_usage): Remove local declaration of *make_host.
2159 (print_version): Display "This program built for ..." after Copyright
2162 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2164 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2165 execution of "makeinfo --html make.texi".
2167 2003-04-30 Paul D. Smith <psmith@gnu.org>
2169 * build.template: Make some changes to maybe allow this script to
2170 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2172 * README.OS2.template: New file for OS/2 support. Original
2173 contributed by Andreas Buening.
2174 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2177 2003-04-19 Paul D. Smith <psmith@gnu.org>
2179 Fix bug #1405: allow a target to match multiple pattern-specific
2182 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2183 variable.c, where they've always belonged.
2184 * rule.h: Move the prototypes and struct pattern_var as well.
2185 * variable.c (initialize_file_variables): Invoke
2186 lookup_pattern_var() in a loop, until no more matches are found.
2187 If a match is found, create a new variable set for the target's
2188 pattern variables. Then merge the contents of each matching
2189 pattern variable set into the target's pattern variable set.
2190 (lookup_pattern_var): Change this function to be usable
2191 in a loop. It takes a starting position: if NULL, start at the
2192 beginning; if non-NULL, start with the pattern variable after that
2193 position, and return the next matching pattern.
2194 (create_pattern_var): Create a unique instance of
2195 pattern-specific variables for every definition in the makefile.
2196 Don't combine the same pattern together. This allows us to
2197 process the variable handling properly even when the same pattern
2198 is used multiple times.
2199 (parse_variable_definition): New function: break out the parsing
2200 of a variable definition line from try_variable_definition.
2201 (try_variable_definition): Call parse_variable_definition to
2203 (print_variable_data_base): Print out pattern-specific variables.
2204 * variable.h (struct variable): Remember when a variable is
2205 conditional. Also remember its flavor.
2206 (struct pattern_var): Instead of keeping a variable set, we just
2207 keep a single variable for each pattern.
2208 * read.c (record_target_var): Each pattern variable contains only a
2209 single variable, not a set, so create it properly.
2210 * doc/make.texi (Pattern-specific): Document the new behavior.
2212 2003-04-17 Paul D. Smith <psmith@gnu.org>
2214 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2215 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2216 file/directory naming rules for VMS so I can't tell whether this
2219 2003-04-09 Paul D. Smith <psmith@gnu.org>
2221 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2222 DOS-style pathnames: backslash separators and drive specifiers.
2224 2003-03-28 Paul D. Smith <psmith@gnu.org>
2226 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2227 the intermediate flag on all targets. Fixes bug #2515.
2229 2003-03-24 Paul D. Smith <psmith@gnu.org>
2231 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2232 Upgrade to autoconf 2.57 and automake 1.7.3.
2234 * job.c: More OS/2 changes from Andreas Buening.
2236 * file.c (print_file): Fix variable initialization.
2239 * remake.c (notice_finished_file):
2241 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2242 some calls (like readdir()) return NULL in valid situations
2243 without resetting errno. Fixes bug #2846.
2245 2003-02-25 Paul D. Smith <psmith@gnu.org>
2247 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2249 * job.c (_is_unixy_shell) [OS/2]: New function.
2250 Set default shell to /bin/sh.
2251 (reap_children): Close the job_rfd pipe here since we don't use a
2253 (set_child_handler_action_flags): define this to empty on OS/2.
2254 (start_job_command): Close the jobserver pipe and use
2255 child_execute_job() instead of fork/exec.
2256 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2257 rather than exec'ing, then reconfigure stdin/stdout.
2258 (exec_command): Rewrite to use spawn instead of exec. Return the
2261 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2262 in DOS. Handle the TEMP environment variable as in DOS. Don't
2263 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2264 use -j in DOS mode. Use child_execute_job() instead of
2267 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2270 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2271 prototypes that return values.
2273 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2275 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2276 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2278 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2281 2003-02-24 Paul D. Smith <psmith@gnu.org>
2283 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2284 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2285 (child_execute_job) [VMS]: Handle error status properly.
2286 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2288 * function.c (func_shell): Use EINTRLOOP() while reading from the
2289 subshell pipe (Fixes bug #2502).
2290 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2292 * main.c (main): Ditto.
2294 2003-01-30 Paul D. Smith <psmith@gnu.org>
2296 * read.c (eval): eval() was not fully reentrant, because the
2297 collapsed buffer was static. Change it to be an automatic
2298 variable so that eval() can be invoked recursively.
2300 (eval): Apply patch # 1022: fix memory reference error on long
2301 target-specific variable lines.
2302 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2304 * function.c (check_numeric): Combine the is_numeric() function
2305 into this function, since it's only called from one place.
2306 Constify this function. Have it print the incorrect string in the
2307 error message. Fixes bug #2407.
2308 (strip_whitespace): Constify.
2309 (func_if): Constify.
2310 * expand.c (expand_argument): Constify.
2312 2003-01-29 Paul D. Smith <psmith@gnu.org>
2314 Fix bug # 2169, also reported by other people on various systems.
2316 * make.h: Some systems, such as Solaris and PTX, do not fully
2317 implement POSIX-compliant SA_RESTART functionality; important
2318 system calls like stat() and readdir() can still fail with EINTR
2319 even if SA_RESTART has been set on the signal handler. So,
2320 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2321 EINTR for system calls which return -1 or 0 (NULL), respectively,
2323 Also, remove the old atomic_stat()/atomic_readdir() and
2324 HAVE_BROKEN_RESTART handling.
2326 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2328 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2329 * remake.c (touch_file): Ditto.
2331 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2332 * read.c (construct_include_path): Ditto.
2333 * remake.c (name_mtime): Ditto.
2334 * vpath.c (selective_vpath_search): Ditto.
2335 * dir.c (find_directory): Ditto.
2336 (local_stat): Ditto.
2337 (find_directory): Use ENULLLOOP() to wrap opendir().
2338 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2340 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2341 atomic_readdir() handling.
2343 2003-01-22 Paul D. Smith <psmith@gnu.org>
2345 * function.c (func_call): Fix Bug #1744. If we're inside a
2346 recursive invocation of $(call ...), mask any of the outer
2347 invocation's arguments that aren't used by this one, so that this
2348 invocation doesn't "inherit" them accidentally.
2350 2002-12-05 Paul D. Smith <psmith@gnu.org>
2352 * function.c (subst_expand): Valery Khamenia reported a
2353 pathological performance hit when doing substitutions on very
2354 large values with lots of words: turns out we were invoking
2355 strlen() a ridiculous number of times. Instead of having each
2356 call to sindex() call strlen() again, keep track of how much of
2357 the text we've seen and pass the length to sindex().
2359 2002-11-19 Paul D. Smith <psmith@gnu.org>
2361 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2364 2002-11-16 Paul D. Smith <psmith@gnu.org>
2366 * NMakefile.template (OBJS): Add hash.c object file.
2367 * SMakefile.template (srcs): Ditto.
2368 * Makefile.ami (objs): Ditto.
2369 * build_w32.bat: Ditto.
2371 * Makefile.DOS.template: Remove extra dependencies.
2373 2002-10-25 Paul D. Smith <psmith@gnu.org>
2375 * expand.c (install_variable_buffer): New function. Install a new
2376 variable_buffer context and return the previous one.
2377 (restore_variable_buffer): New function. Free the current
2378 variable_buffer context and put a previously saved one back.
2379 * variable.h: Prototypes for {install,restore}_variable_buffer.
2380 * function.c (func_eval): Push a new variable_buffer context
2381 before we eval, then restore the old one when we're done.
2384 * read.c (install_conditionals): New function. Install a new
2385 conditional context and return the previous one.
2386 (restore_conditionals): New function. Free the current
2387 conditional context and put a previously saved one back.
2388 (eval): Use the {install,restore}_conditionals for "include"
2390 (eval_buffer): Use {install,restore}_conditionals to preserve the
2391 present conditional state before we evaluate the buffer.
2394 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2396 (Recursion): Add a variable index entry for CURDIR.
2398 * README.cvs: Update to appropriate versions.
2399 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2400 don't need to copy loadavg.c: automake is smart enough to create
2401 it for me. Still have a bug in automake related to ansi2knr tho.
2403 2002-10-14 Paul D. Smith <psmith@gnu.org>
2405 * remake.c (notice_finished_file): Only touch targets if they have
2406 at least one command (as per POSIX). Resolve Bug #1418.
2408 * *.c: Convert to using ANSI C-style function definitions.
2409 * Makefile.am: Enable the ansi2knr feature of automake.
2410 * configure.in: ditto.
2412 2002-10-13 Paul D. Smith <psmith@gnu.org>
2414 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2415 for automatic variable values like $^, etc. In the case of very
2416 large lists of prerequisites this causes problems. Instead reuse
2417 a static buffer (resizeable) for each variable.
2419 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2420 target-specific variable definitions. Check for it and set an
2422 (record_target_var): Set the export field to v_export if the
2423 "exported" flag is set.
2424 * doc/make.texi (Target-specific): Document the ability to use
2427 * doc/make.texi: Change the name of the section on automatic
2428 variables from "Automatic" to "Automatic Variables". Added text
2429 clarifying the scope of automatic variables.
2431 2002-10-04 Paul D. Smith <psmith@gnu.org>
2433 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2435 (record_files): Ditto.
2437 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2438 the search for the '=' to only within the enclosing parens.
2440 2002-10-03 Paul D. Smith <psmith@gnu.org>
2442 Version 3.80 released.
2444 * dir.c: Change hash functions to use K&R function definition style.
2445 * function.c: Ditto.
2447 * variable.c: Ditto.
2449 Update to automake 1.7.
2451 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2452 (pdf): Remove this target as automake now provides one.
2454 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2456 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2458 * makefile.com: Updates for GNU make 3.80.
2459 * makefile.vms: Ditto.
2461 2002-09-23 Paul D. Smith <psmith@gnu.org>
2463 * read.c (enum make_word_type): Remove w_comment.
2464 (get_next_mword): Don't treat comment characters as special; where
2465 this function is used we will never see a comment (it's stripped
2466 before we get here) and treating comments specially means that
2467 targets like "foo\#bar" aren't handled properly.
2469 2002-09-18 Paul D. Smith <psmith@gnu.org>
2471 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2473 * read.c (eval): Expansion of arguments to export/unexport was
2474 ignoring all arguments after the first one. Change the algorithm
2475 to expand the whole line once, then parse the results.
2477 2002-09-17 Paul D. Smith <psmith@gnu.org>
2479 Fix Bug #940 (plus another bug I found while looking at this):
2481 * read.c (record_target_var): enter_file() will add a new entry if
2482 it's a double-colon target: we don't want to do that in this
2483 situation. Invoke lookup_file() and only enter_file() if it does
2484 not already exist. If the file we get back is a double-colon then
2485 add this variable to the "root" double-colon target.
2487 * variable.c (initialize_file_variables): If this file is a
2488 double-colon target but is not the "root" target, then initialize
2489 the root and make the root's variable list the parent of our
2492 2002-09-13 Paul D. Smith <psmith@gnu.org>
2494 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2496 * hash.c (round_up_2): Get rid of a warning.
2498 2002-09-12 Paul D. Smith <psmith@gnu.org>
2500 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2501 so it doesn't complain about getloadavg.c.
2503 * commands.c (set_file_variables): Make sure we always alloca() at
2504 least 1 character for the value of $? (for '\0').
2506 2002-09-11 Paul D. Smith <psmith@gnu.org>
2508 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2509 macro to use RESULT instead of the incorrect _RESULT_.
2511 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2512 and atomic_readdir(). We need to #include dirent.h to get this to
2514 * misc.c (atomic_readdir): Fix typos.
2516 2002-09-10 Paul D. Smith <psmith@gnu.org>
2518 * read.c (eval): Expand variable lists given to export and
2519 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2520 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2522 * doc/make.texi (Variables/Recursion): Document this.
2523 (Conditional Syntax): And here.
2525 2002-09-09 Paul D. Smith <psmith@gnu.org>
2527 * configure.in: Check for memmove().
2529 2002-09-07 Paul D. Smith <psmith@gnu.org>
2531 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2532 Michael Sterrett <msterret@coat.com> reports that while it has
2533 SA_RESTART, it does not work properly.
2535 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2536 that invokes stat() and loops to do it again if it returns EINTR.
2537 (atomic_readdir): Ditto, with readdir().
2539 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2540 and readdir() to atomic_stat() and atomic_readdir().
2542 2002-09-04 Paul D. Smith <psmith@gnu.org>
2544 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2545 reports that GNU make sometimes doesn't recognize that targets can
2546 be made, when directories can be created as prerequisites. He
2547 reports that changing the order of predicates in the DEP->changed
2548 flag test so that lookup_file() is always performed, solves this
2551 2002-08-08 Paul D. Smith <psmith@gnu.org>
2553 * configure.in: Require a newer version of gettext.
2555 * misc.c (perror_with_name): Translate the format string (for
2556 right-to-left language support).
2557 (pfatal_with_name): Ditto.
2559 * main.c: Create a static array of strings to store the usage
2560 text. This is done to facilitate translations.
2561 (struct command_switch): Remove argdesc and description fields.
2562 (switches): Remove values for obsolete fields.
2563 (print_usage): Print each element of the usage array.
2565 * hash.c: Change function definitions to be K&R style.
2567 2002-08-02 Paul D. Smith <psmith@gnu.org>
2569 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2570 this one because it's too hard to get right. We'll look at it for
2572 * main.c (main): Don't create the .TARGETS variable.
2573 * variable.c (handle_special_var): Don't handle .TARGETS.
2575 2002-08-01 Paul D. Smith <psmith@gnu.org>
2577 * main.c (switches): Add a new option, -B (--always-make). If
2578 specified, make will rebuild all targets that it encounters even
2579 if they don't appear to be out of date.
2580 (always_make_flag): New flag.
2581 * make.h: Extern always_make_flag.
2582 * remake.c (update_file_1): Check always_make_flag; if it's set we
2583 will always rebuild any target we can, even if none of its
2584 prerequisites are newer.
2587 * doc/make.texi (Shell Function): Make it clear that make
2588 variables marked as "export" are not passed to instances of the
2591 Add new introspection variable .VARIABLES and .TARGETS.
2593 * variable.c (handle_special_var): New function. If the variable
2594 reference passed in is "special" (.VARIABLES or .TARGETS),
2595 calculate the new value if necessary. .VARIABLES is handled here:
2596 walk through the hash of defined variables and construct a value
2597 which is a list of the names. .TARGETS is handled by
2598 build_target_list().
2599 (lookup_variable): Invoke handle_special_var().
2600 * file.c (build_target_list): Walk through the hask of known files
2601 and construct a list of the names of all the ones marked as
2603 * main.c (main): Initialize them to empty (and as simple variables).
2604 * doc/make.texi (Special Variables): Document them.
2605 * NEWS: Mention them.
2607 * variable.h (struct variable): Add a new flag "exportable" which
2608 is true if the variable name is valid for export.
2609 * variable.c (define_variable_in_set): Set "exportable" when a new
2610 variable is defined.
2611 (target_environment): Use the "exportable" flag instead of

2643 GNU id-utils package:
2645 2002-07-10 Greg McGary <greg@mcgary.org>
2647 * scripts/functions/filter-out: Add literals to to the
2648 pattern space in order to add complexity, and trigger
2649 use of an internal hash table. Fix documentation strings.
2650 * scripts/targets/INTERMEDIATE: Reverse order of files
2651 passed to expected `rm' command.
2653 2002-07-10 Greg McGary <greg@mcgary.org>

2745 2002-07-10 Paul D. Smith <psmith@gnu.org>
2747 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2748 prerequisite list. A real SysV make will expand the entire
2749 prerequisites list _twice_: we don't do that as it's a big
2750 backward-compatibility problem. We only replace those specific
2753 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2754 references left in the list of prerequisites. Check for .POSIX as
2755 we record targets, so we can disable non-POSIX behavior while
2756 reading makefiles as well as running them.
2757 (eval): Check the prerequisite list to see if we have anything
2758 that looks like a SysV prerequisite variable reference.
2760 2002-07-09 Paul D. Smith <psmith@gnu.org>
2762 * doc/make.texi (Prerequisite Types): Add a new section describing
2763 order-only prerequisites.
2765 * read.c (uniquize_deps): If we have the same file as both a
2766 normal and order-only prereq, get rid of the order-only prereq,
2767 since the normal one supersedes it.
2769 2002-07-08 Paul D. Smith <psmith@gnu.org>
2771 * AUTHORS: Added Greg McGary to the AUTHORS file.
2772 * NEWS: Blurbed order-only prerequisites.
2773 * file.c (print_file): Show order-only deps properly when printing
2776 * maintMakefile: Add "update" targets for wget'ing the latest
2777 versions of various external files. Taken from Makefile.maint in
2780 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2781 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2783 2002-07-07 Paul D. Smith <psmith@gnu.org>
2785 * po/*.po: Remove. We'll use wget to retrieve them at release
2788 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2789 rather than a shell you get an exception. Make sure we look up
2790 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2792 * remake.c (notice_finished_file): Fix handling of -t flag.
2793 Patch provided by Henning Makholm <henning@makholm.net>.
2795 * implicit.c (pattern_search): Some systems apparently run short
2796 of stack space, and using alloca() in this function caused an
2797 overrun. I modified it to use xmalloc() on the two variables
2798 which seemed like they might get large. Fixes Bug #476.
2800 * main.c (print_version): Update copyright notice to conform with
2802 (print_usage): Update help output.
2804 * function.c (func_eval): Create a new make function, $(eval
2805 ...). Expand the arguments, put them into a buffer, then invoke
2806 eval_buffer() on the resulting string.
2807 (func_quote): Create a new function, $(quote VARNAME). Inserts
2808 the value of the variable VARNAME without expanding it any
2811 * read.c (struct ebuffer): Change the linebuffer structure to an
2812 "eval buffer", which can be either a file or a buffer.
2813 (eval_makefile): Move the code in the old read_makefile() which
2814 located a makefile into here: create a struct ebuffer with that
2815 information. Have it invoke the new function eval() with that
2817 (eval_buffer): Create a new function that creates a struct ebuffer
2818 that holds a string buffer instead of a file. Have it invoke
2819 eval() with that ebuffer.
2820 (eval): New function that contains the guts of the old
2821 read_makefile() function: this function parses makefiles. Obtains
2822 data to parse from the provided ebuffer. Some modifications to
2823 make the flow of the function cleaner and clearer. Still could
2824 use some work here...
2825 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2826 contents of the define/endef variable from the ebuffer.
2827 (readstring): Read the next line from a string-style ebuffer.
2828 (readline): Read the next line from an ebuffer. If it's a string
2829 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2832 * dep.h (eval_buffer): Prototype eval_buffer();
2834 * variable.c (do_variable_definition): Make sure that all
2835 non-target-specific variables are registered in the global set.
2836 If we're invoked from an $(eval ...) we might be inside a $(call
2837 ...) or other function which has pushed a variable scope; we still
2838 want to define our variables from evaluated makefile code in the
2841 2002-07-03 Greg McGary <greg@mcgary.org>
2843 * dep.h (struct dep) [ignore_mtime]: New member.
2844 [changed]: convert to a bitfield.
2845 * implicit.c (pattern_search): Zero ignore_mtime.
2846 * main.c (main, handle_non_switch_argument): Likewise.
2847 * rule.c (convert_suffix_rule): Likewise.
2848 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2849 (read_makefile): Parse '|' in prerequisite list.
2850 (uniquize_deps): Consider ignore_mtime when comparing deps.
2851 * remake.c (update_file_1, check_dep): Don't force remake for
2852 dependencies that have d->ignore_mtime.
2853 * commands.c (FILE_LIST_SEPARATOR): New constant.
2854 (set_file_variables): Don't include a
2855 prerequisite in $+, $^ or $? if d->ignore_mtime.
2858 2002-06-18 Paul D. Smith <psmith@gnu.org>
2860 * make.texinfo: Updates for next revision. New date/rev/etc.
2861 Recreate all Info menus. Change license on the manual to the GNU
2862 Free Documentation License. A number of typos.
2863 (Variables Simplify): Don't use "-" before it's defined.
2864 (Automatic Prerequisites): Rewrite the target example to work
2865 properly if the compile fails. Remove incorrect comments about
2866 how "set -e" behaves.
2867 (Text Functions): Move the "word", "wordlist", "words", and
2868 "firstword" functions here, from "File Name Functions".
2869 * make-stds.texi: Update from latest GNU version.
2870 * fdl.texi: (created) Import the latest GNU version.
2872 2002-06-06 Paul D. Smith <psmith@gnu.org>
2874 * variable.c (do_variable_definition): New function: extract the
2875 part of try_variable_definition() that actually sets the value
2876 into a separate function.
2877 (try_variable_definition): Call do_variable_definition() after
2878 parsing the variable definition string.
2879 (define_variable_in_set): Make the name argument const.
2881 * variable.h (enum variable_flavor): Make public.
2882 (do_variable_definition): Create prototype.
2884 * read.c (read_all_makefiles): Create a new built-in variable,
2886 (read_makefile): Add each makefile read in to this variable value.
2888 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2890 * Makefile.DOS.template: Tweak according to changes in the
2891 distribution. Add back the dependencies of *.o files.
2893 * configh.dos.template: Synchronize with config.h.in.
2895 2002-05-09 Paul D. Smith <psmith@gnu.org>
2897 * file.c (file_timestamp_now): Use K&R function declaration.
2899 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2900 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2901 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2902 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2903 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2904 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2905 nlist.n_name is a pointer rather than an array.
2907 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2908 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2909 * configure.in: Use it instead of the old version.
2911 * main.c (main): Prefer setvbuf() to setlinebuf().
2913 2002-05-08 Paul D. Smith <psmith@gnu.org>
2915 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2916 (loadavg_LDADD): Ditto.
2918 2002-04-29 Paul D. Smith <psmith@gnu.org>
2920 * expand.c (recursively_expand_for_file): Rename
2921 recursively_expand() to recursively_expand_for_file() and provide
2922 an extra argument, struct file. If the argument is provided, set
2923 the variable scope to that of the file before expanding.
2924 * variable.h (recursively_expand): Make this a macro that invokes
2925 recursively_expand_for_file() with a NULL file pointer.
2926 * variable.c (target_environment): Call the renamed function and
2927 provide the current file context.
2928 Fixes Debian bug #144306.
2930 2002-04-28 Paul D. Smith <psmith@gnu.org>
2932 Allow $(call ...) user-defined variables to be self-referencing
2933 without throwing an error. Allows implementation of transitive
2934 closures, among other possibly useful things.
2935 Requested by: Philip Guenther <guenther@sendmail.com>
2937 * variable.h (struct variable): Add a new field: exp_count, and
2938 new macros to hold its size and maximum value.
2939 (warn_undefined): Make this a macro.
2940 * variable.c (define_variable_in_set): Initialize it.
2941 * expand.c (recursively_expand): If we detect recursive expansion
2942 of a variable, check the exp_count field. If it's greater than 0
2943 allow the recursion and decrement the count.
2944 (warn_undefined): Remove this (now a macro in variable.h).
2945 * function.c (func_call): Before we expand the user-defined
2946 function, modify its exp_count field to contain the maximum
2947 number of recursive calls we'll allow. After the call, reset it
2950 2002-04-21 Paul D. Smith <psmith@gnu.org>
2952 Modified to use latest autoconf (2.53), automake (1.6.1), and
2953 gettext (0.11.1). We're using gettext's new "external" support,
2954 to avoid including libintl source with GNU make.
2956 * README.cvs: New file. Explain how to build GNU make from CVS.
2958 * configure.in: Modify checking for the system glob library.
2959 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2960 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2961 etc. will manage it correctly). Set an automake conditional
2962 USE_LOCAL_GLOB to decide whether to compile the glob library.
2964 * getloadavg.c (main): Include make.h in the "TEST" program to
2967 * Makefile.am: Remove special rules for loadavg. Replace them
2968 with Automake capabilities for building extra programs.
2970 * signame.c: This file does nothing if the system provide
2971 strsignal(). If not, it implements strsignal(). If the system
2972 doesn't define sys_siglist, then we make our own; otherwise we use
2974 * signame.h: Removed.
2976 * main.c (main): No need to invoke signame_init(). Update copyright.
2978 * ABOUT-NLS: Removed.
2979 * gettext.c: Removed.
2980 * gettext.h: Get a simplified copy from the gettext package.
2982 * i18n/*.po: Moved to po/.
2985 * config/*: Created. Contains package configuration helper files.
2986 * config.guess, config.sub: Moved to config directory.
2988 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2989 Rework to use new-style autoconf features. Use the "external"
2990 mode for gettext. Make the build.sh config file conditional on
2991 whether build.sh.in exists, to avoid autoconf errors.
2992 * acinclude.m4: Removed almost all macros as being obsolete.
2993 Rewrote remaining macros to use AC_DEFINE.
2994 * acconfig.h: Removed.
2996 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2997 conditional to handle customs support. Remove special handling
3000 2002-04-20 Paul D. Smith <psmith@gnu.org>
3002 * function.c (func_call): Don't mark the argument variables $1,
3003 etc. as recursive. They've already been fully expanded so
3004 there's no need to do it again, and doing so strips escaped $'s.
3005 Reported by Sebastian Glita <glseba@yahoo.com>.
3007 * remake.c (notice_finished_file): Walk through double-colon
3008 entries via the prev field, not the next field!
3009 Reported by Greg McGary <greg@mcgary.org>.
3011 * main.c (main): If the user specifies -q and asks for a specific
3012 target which is a makefile, we got an assert. In that case it
3013 turns out we should continue normally instead.
3015 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3017 * i18n/he.po: Installed a new translation.
3019 2002-01-07 Paul D. Smith <psmith@gnu.org>
3021 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3023 2001-12-04 Paul D. Smith <psmith@gnu.org>
3025 * i18n/ja.po: Installed an updated translation.
3027 2001-09-06 Paul Eggert <eggert@twinsun.com>
3029 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3030 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3032 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3034 (main): Get rid of any avoidable limit on stack size.
3036 2001-09-04 Paul D. Smith <psmith@gnu.org>
3038 * i18n/da.po: Installed an updated translation.
3040 2001-08-03 Paul D. Smith <psmith@gnu.org>
3042 * i18n/fr.po: Installed an updated translation.
3043 Resolves Debian bug #106720.
3045 2001-06-13 Paul D. Smith <psmith@gnu.org>

3050 2001-06-11 Paul D. Smith <psmith@gnu.org>
3052 * i18n/ko.po: Installed a new translation.
3054 2001-05-06 Paul D. Smith <psmith@gnu.org>
3056 Modify the EINTR handling.
3058 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3059 the way in which we manage the file descriptor/signal handler race
3060 trap to be more efficient.
3062 2001-05-06 Paul Eggert <eggert@twinsun.com>
3064 Restart almost all system calls that are interrupted, instead
3065 of worrying about EINTR. The lone exception is the read() for
3068 * configure.in (HAVE_SA_RESTART): New macro.
3069 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3070 * main.c (main): Use SA_RESTART instead of the old,
3071 nonstandard SA_INTERRUPT.
3073 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3074 * main.c (bsd_signal): New function or macro,
3075 if the implementation doesn't supply it.
3076 (The bsd_signal function will be in POSIX 1003.1-200x.)
3077 (HANDLESIG): Remove.
3078 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3080 * make.h (EINTR_SET): Remove.
3081 (SA_RESTART): New macro.
3083 * arscan.c (ar_member_touch): Don't worry about EINTR.
3084 * function.c (func_shell): Likewise.
3085 * job.c (reap_children, free_child, new_job): Likewise.
3086 * main.c (main): Likewise.
3087 * remake.c (touch_file, name_mtime): Likewise.
3089 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3090 if fstat failed with errno!=EINTR, the error was ignored.
3092 * job.c (set_child_handler_action_flags): New function.
3093 (new_job): Use it to temporarily clear the SIGCHLD action flags
3094 while reading the token.
3096 2001-05-02 Paul D. Smith <psmith@gnu.org>
3098 * job.c (start_job_command): Don't add define/endef per-line flags
3099 to the top-level flags setting.
3101 2001-04-03 Paul D. Smith <psmith@gnu.org>
3103 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3104 bit on error, so check for odd return values, not non-0 return
3106 (VMS_get_member_info): Calculate the timezone differences correctly.
3107 Reported by John Fowler <jfowler@nyx.net>.
3110 2001-03-14 Paul D. Smith <psmith@gnu.org>
3112 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3113 value before invoking define_variable().
3114 Reported by John Fowler <jfowler@nyx.net>.
3116 2001-02-07 Paul D. Smith <psmith@gnu.org>
3118 * read.c (record_target_var): If we reset the variable due to a
3119 command-line variable setting overriding it, turn off the "append"
3122 2001-01-17 Paul D. Smith <psmith@gnu.org>
3124 * variable.c (lookup_variable) [VMS]: When getting values from the
3125 environment, allocate enough space for the _value_ plus escapes,
3126 not enough space for the name plus escapes :-/.
3127 Reported by John Fowler <jfowler@nyx.net>.
3129 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3130 warnings that make generates, so it doesn't look like an error.
3131 Reported by Karl Berry <karl@gnu.org>.
3134 Fix for PR/2020: Rework appended target-specific variables. I'm
3135 fairly confident this algorithm is finally correct.
3137 * expand.c (allocated_variable_append): Rewrite. Instead of
3138 expanding each appended variable then adding all the expanded
3139 strings together, we append all the unexpanded values going up
3140 through the variable set contexts, then expand the final result.
3141 This behaves just like non-target-specific appended variable
3142 values, while the old way didn't in various corner cases.
3143 (variable_append): New function: recursively append the unexpanded
3144 value of a variable, walking from the outermost variable scope to
3146 * variable.c (lookup_variable): Remove the code that looked up the
3147 variable set list if the found variable was "append". We don't
3149 (lookup_variable_in_set): Make this non-static so we can use it
3151 (try_variable_definition): Use lookup_variable_in_set() rather
3152 than faking out current_variable_set_list by hand (cleanup).
3153 * variable.h: Add a prototype for the now non-static
3154 lookup_variable_in_set().
3156 2000-11-17 Paul D. Smith <psmith@gnu.org>
3158 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3159 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3160 before throwing a fit.
3162 2000-11-17 Paul D. Smith <psmith@gnu.org>
3164 * read.c (readline): CRLF calculations had a hole, if you hit the
3165 buffer grow scenario just right. Reworked the algorithm to avoid
3166 the need for len or lastlen at all. Problem description with
3167 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3169 2000-10-24 Paul D. Smith <psmith@gnu.org>
3171 * gettext.c (SWAP): Declare this with the prototype, otherwise
3172 some systems don't work (non-32-bit? Reported for Cray T3E).
3173 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3175 2000-10-05 Paul D. Smith <psmith@gnu.org>
3177 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3178 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3180 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3182 2000-09-22 Paul D. Smith <psmith@gnu.org>
3184 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3185 parts of the real gettext.h here, and we expect to really include
3186 the real gettext.h later. If we keep this #define, it's ignored.
3188 2000-09-21 Paul D. Smith <psmith@gnu.org>
3190 * main.c (log_working_directory): Rework the text to use complete
3191 sentences, to make life simpler for the translators.
3193 2000-08-29 Paul D. Smith <psmith@gnu.org>
3195 * file.c (remove_intermediates): Print a debug message before we
3196 remove intermediate files, so the user (if she uses -d) knows
3199 2000-08-21 Paul D. Smith <psmith@gnu.org>
3201 * variable.c (try_variable_definition): Change how we handle
3202 target-specific append variable defns: instead of just setting the
3203 value, expand it as an append _but_ only within the current
3204 target's context. Otherwise we lose all but the last value if the
3205 variable is appended more than once within the current target
3206 context. Fixes PR/1831.
3208 2000-08-16 Paul D. Smith <psmith@gnu.org>
3210 * function.c (func_shell): Nul-terminate the buffer before
3211 printing an exec error message (just in case it's not!).
3212 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3214 2000-07-25 Paul D. Smith <psmith@gnu.org>
3216 * job.c (construct_command_argv_internal): Add "~" to the list of
3217 sh_chars[] which disallow optimizing out the shell call.
3219 2000-07-23 Paul Eggert <eggert@twinsun.com>
3221 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3222 supersedes --disable-nsec-timestamps.
3223 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3224 * README: Remove --disable-nsec-timestamps.
3226 * filedef.h (struct file.low_resolution_time): New member.
3227 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3228 * remake.c (update_file_1):
3229 Avoid spurious rebuilds due to low resolution time stamps,
3230 generalizing the earlier code that applied only to archive members.
3231 (f_mtime): Archive members always have low resolution time stamps.
3233 * configure.in: Remove --disable-nsec-timestamps, as this has
3234 been superseded by .LOW_RESOLUTION_TIME.
3236 2000-07-23 Paul Eggert <eggert@twinsun.com>
3238 * configure.in (enable_nsec_timestamps): Renamed from
3239 make_cv_nsec_timestamps, since enable/disable options
3240 shouldn't be cached.
3242 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3243 and Paul Eggert <eggert@twinsun.com>
3245 * file.c (file_timestamp_now):
3246 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3247 so that clock_gettime is not linked unless needed.
3249 * filedef.h (FILE_TIMESTAMP_HI_RES):
3250 Remove definition; "configure" now does this.
3252 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3253 to before high resolution file timestamp check,
3254 since that check now uses uintmax_t.
3255 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3256 high resolution file timestamps.
3257 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3258 so that we don't link in clock_gettime unnecessarily.
3260 2000-07-17 Paul D. Smith <psmith@gnu.org>
3262 * i18n/ja.po: New version of the translation file.
3264 2000-07-07 Paul D. Smith <psmith@gnu.org>
3266 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3267 the offset calculation.
3268 (name_mtime): Replace EINTR test with EINTR_SET macro.
3270 2000-07-07 Paul Eggert <eggert@twinsun.com>
3274 * remake.c (update_file_1):
3275 Avoid spurious rebuilds of archive members due to their
3276 timestamp resolution being only one second.
3277 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3278 the clock's resolution being lower than file timestamps'.
3279 When warning about future timestamps, report only the discrepancy,
3280 not the absolute value of the timestamp and the current time.
3282 * file.c (file_timestamp_now): New arg RESOLUTION.
3283 * filedef.h (file_timestamp_now): Likewise.
3284 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3286 2000-07-05 Paul D. Smith <psmith@gnu.org>
3288 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3289 to listp. Fixes PR/1793.
3291 2000-06-26 Paul Eggert <eggert@twinsun.com>
3293 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3295 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3297 * remake.c (f_mtime): Remove unused var memtime.
3299 2000-06-25 Martin Buchholz <martin@xemacs.org>
3301 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3302 Ran spell-check on make.texinfo.
3304 2000-06-23 Paul D. Smith <psmith@gnu.org>
3306 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3307 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3308 * make.h: Define these macros.
3310 * Version 3.79.1 released.
3312 * configure.in: Add a new option, --disable-nsec-timestamps, to
3313 avoid using sub-second timestamps on systems that support it. It
3314 can lead to problems, e.g. if your makefile relies on "cp -p".
3315 * README.template: Document the issue with "cp -p".
3317 * config.guess, config.sub: Updated.
