139 command scripts. Prefix the command scripts with cmd_prefix, not \t.
140
141 * read.c (construct_include_path): Add the full string to the cache; we
142 were chopping the last char.
143
144 * NEWS: Announce the .RECIPEPREFIX special variable.
145 * variable.c (lookup_special_var): Rename from handle_special_var().

152 * main.c (main): Create the .RECIPEPREFIX special variable.

154 scripts here, so they're not stored in the commands array at all,
155 rather than waiting and stripping them out during command construction.
156 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
157
1582007-08-15 Paul Smith <psmith@gnu.org>
159
160 * doc/make.texi (GNU Free Documentation License): The fdl.texi
161 file has had the section info removed, so add some to make.texi
162 before we include it.
163
1642007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
165
166 * remake.c (check_dep): Reset the target state for intermediate
167 files. They might have been considered before but not updated
168 then (order-only for example) but they will be this time.

175 value of FLAGS.
176 * job.c (construct_command_argv_internal): New argument FLAGS; all

181
1822007-07-13 Paul Smith <psmith@gnu.org>

187 Fixes Savannah bug #20452.
188
1892007-07-04 Paul Smith <psmith@gnu.org>
190
191 * (ALL FILES): Update to GPLv3.

204 Fixes Savannah bug #20018.
205

207 reading_file rather than setting it to 0 at the end.
208 Fixes Savannah bug #20033.
209
2102007-05-11 Paul Smith <psmith@gnu.org>
211
212 * job.c (new_job): Add debug info to specify where make found the
213 command script it is running to build a target.
214 Fixes Savannah bug #18617.
215
216 * default.c (default_suffixes,default_suffix_rules,default_variables):
217 Add support for Objective C. Fixes Savannah bug #16389.
218 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.

221
222 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
223 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
224 Dave Korn <dave.korn@artimi.com>
225
2262007-05-08 Paul Smith <psmith@gnu.org>
227
228 Fix Savannah bug #19656:
229
230 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
231
232 * make.h: Change all case-insensitive string compares to use
233 strcasecmp() (from POSIX). If we don't have that but do have one
234 of the others, define strcasecmp to be one of those instead. If
235 we don't have any, declare a prototype for our own version.
236
237 * misc.c (strcasecmp): Use this if we can't find any native
238 case-insensitive string comparison function.
239 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
240 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
241 strcmpi().
242 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
243 strcasecmp() instead of stricmp().
244 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
245 instead of strcmpi().
246 * acinclude.m4: Remove the strcasecmp() check from here.
247
2482007-03-21 Paul Smith <psmith@gnu.org>
249
250 * configure.in: Don't turn on case-insensitive file system support
251 if --disable-... is given. Fixes Savannah bug #19348.
252
2532007-03-19 Paul Smith <psmith@gnu.org>
254
255 * ALL: Use the strcache for all file name strings, or other
256 strings which we will never free. The goal is to save memory by
257 avoiding duplicate copies of strings. However, at the moment this
258 doesn't save much memory in most situations: due to secondary
259 expansion we actually save prerequisite lists twice (once before
260 the secondary expansion, and then again after it's been parsed
261 into individual file names in the dep list). We will resolve this
262 in a future change, by doing the parsing up-front for targets
263 where secondary expansion is not set.
264
265 Moving things into the strcache also allows us to use const
266 pointers in many more places.
267
2682007-01-03 Paul Smith <psmith@gnu.org>
269
270 * make.h (ENULLLOOP): Reset errno after each failed invocation of
271 the function, not just the first. Fixes Savannah bug #18680.
272
2732006-11-18 Paul Smith <psmith@gnu.org>
274
275 * strcache.c (strcache_add_len): Don't allocate a new buffer
276 unless the string is not already nil-terminated. Technically this
277 is a violation of the standard, since we may be passed an array
278 that is not long enough to test one past. However, in make this
279 is never true since we only use nil-terminated strings or
280 sub-strings thereof.
281
282 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
283
284 * main.c: New global cmd_prefix, defaults to '\t'.
285 * job.c (construct_command_argv_internal): Use cmd_prefix instead
286 of '\t'.
287
288 * dir.c: Constified.
289 (dir_contents_file_exists_p): Check for an error return from
290 readdir(), just in case.
291
292 * commands.c: Constified.
293 * default.c: Constified.
294 * expand.c: Constified.
295 * function.c: Partial constification.
296 * variable.c: Partial constification.
297 * vmsify.c: Constification. Hard to test this but I hope I didn't
298 screw it up!
299 * vpath.c: Partial constification.
300 * w32/pathstuff.c: Partial constification.
301
3022006-11-16 Eli Zaretskii <eliz@gnu.org>
303
304 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
305 backslashes and drive letters as absolute.
306
3072006-10-22 Paul Smith <psmith@gnu.org>
308
309 * main.c (struct command_switch): Use const and void*.
310
3112006-10-21 Paul Smith <psmith@gnu.org>
312
313 * ar.c: Constified.
314 * arscan.c: Constified.
315
3162006-09-30 Paul Smith <psmith@gnu.org>
317
318 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
319 point to lastword since the example was updated.
320 Fixes Savannah bug #16304.
321 (Secondary Expansion): Correct example description.
322 Fixes Savannah bug #16468.
323 (Makefile Contents): Clarify that comments cannot appear within
324 variable references or function calls.
325 Fixes Savannah bug #16577.
326 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
327 Fixes Savannah bug #17701.
328 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
329 (Prerequisite Types): Added an example of using order-only
330 prerequisites. Fixes Savannah bug #17880.
331 (Rule Syntax): "lise" -> "list"
332 (Multiple Rules): ... -> @dots{}
333 (Splitting Lines): ditto.
334
335 * remake.c (update_file_1): Prereqs that don't exist should be
336 considered changed, for the purposes of $?.
337 Fixes Savannah bug #16051.
338
339 * make.1: Remove extraneous "+".
340 Fixes Savannah bug #16652.

354 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
355 well.
356
357 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
358 sh_chars_sh for Windows platforms that emulate Unix.

398

443
444 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
445 with lastslash, since the latter points to filename, not to
446 target.
447 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
448 Declare and define sh_chars_sh[].
449
4502006-03-23 Paul D. Smith <psmith@gnu.org>
451
452 * configure.in: Look for build.sh.in in $srcdir so it will be

486 allow multiple concurrent runs.
487 Patch from Joseph Myers <joseph@codesourcery.com>
488
4892006-03-17 Boris Kolpackov <boris@kolpackov.net>
490
491 * dep.h (struct dep): Add the stem field.
492 * misc.c (alloc_dep, free_dep): New functions.
493 (copy_dep_chain): Copy stem.
494 (free_dep_chain): Use free_dep.
495 * read.c (record_files): Store stem in the dependency line.
496 * file.c (expand_deps): Use stem stored in the dependency line. Use
497 free_dep_chain instead of free_ns_chain.
498 * implicit.c (pattern_search): Use alloc_dep and free_dep.
499 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
500 * main.c (main, handle_non_switch_argument): Ditto.
501 * remake.c (check_dep): Ditto.
502 * rule.c (convert_suffix_rule, freerule): Ditto.
503
5042006-03-14 Paul D. Smith <psmith@gnu.org>
505
506 * expand.c (variable_append): Instead of appending everything then
507 expanding the result, we expand (or not, if it's simple) each part
508 as we add it.
509 (allocated_variable_append): Don't expand the final result.
510 Fixes Savannah bug #15913.
511
5122006-03-09 Paul Smith <psmith@gnu.org>
513
514 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
515 listed non-existent files as changed. Turns out there's a bug in
516 the Linux kernel builds which means that this change causes
517 everything to rebuild every time. We will re-introduce this fix
518 in the next release, to give them time to fix their build system.
519 Fixes Savannah bug #16002.
520 Introduces Savannah bug #16051.
521
522 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
523 we *don't* find UNIX "/".
524 Reported by David Ergo <david.ergo@alterface.com>
525
5262006-03-04 Eli Zaretskii <eliz@gnu.org>
527
528 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
529 locator function find_and_set_default_shell if SHELL came from the
530 command line.
531
5322006-02-20 Paul D. Smith <psmith@gnu.org>
533
534 * variable.c (merge_variable_set_lists): It's legal for *setlist0
535 to be null; don't core in that case.
536
5372006-02-19 Paul D. Smith <psmith@gnu.org>
538
539 * commands.c (set_file_variables): Realloc, not malloc, the static
540 string values to avoid memory leaks.
541
542 * expand.c (recursively_expand_for_file): Only set reading_file to
543 an initialized value.
544
545 * implicit.c (pattern_search): We need to make a copy of the stem
546 if we get it from an intermediate dep, since those get freed.
547
548 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
549 begin with ".".
550 (enter_file) [VMS]: Ditto.
551 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
552
5532006-02-24 Eli Zaretskii <eliz@gnu.org>
554
555 * job.c (construct_command_argv_internal): Fix last change.
556
557 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
558 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
559 the calls to _beginthreadex.
560
561 * expand.c (recursively_expand_for_file): Initialize `save' to
562 prevent compiler warnings.
563
5642006-02-18 Eli Zaretskii <eliz@gnu.org>
565
566 * job.c (construct_command_argv_internal): Don't create a temporary
567 script/batch file if we are under -n. Call _setmode to switch the
568 script file stream to text mode.
569
5702006-02-17 Paul D. Smith <psmith@gnu.org>
571
572 * variable.c (merge_variable_set_lists): Don't try to merge the
573 global_setlist. Not only is this useless, but it can lead to
574 circularities in the linked list, if global_setlist->next in one
575 list gets set to point to another list which also ends in
576 global_setlist.
577 Fixes Savannah bug #15757.
578
5792006-02-15 Paul D. Smith <psmith@gnu.org>
580
581 Fix for Savannah bug #106.
582
583 * expand.c (expanding_var): Keep track of which variable we're
584 expanding. If no variable is being expanded, it's the same as
585 reading_file.
586 * make.h (expanding_var): Declare it.
587 * expand.c (recursively_expand_for_file): Set expanding_var to the
588 current variable we're expanding, unless there's no file info in
589 it (could happen if it comes from the command line or a default
590 variable). Restore it before we exit.
591 * expand.c (variable_expand_string): Use the expanding_var file
592 info instead of the reading_file info.
593 * function.c (check_numeric): Ditto.
594 (func_word): Ditto.
595 (func_wordlist): Ditto.
596 (func_error): Ditto.
597 (expand_builtin_function): Ditto.
598 (handle_function): Ditto.
599
6002006-02-14 Paul D. Smith <psmith@gnu.org>
601
602 * read.c (eval): Even if the included filenames expands to the
603 empty string we still need to free the allocated buffer.
604
605 * implicit.c (pattern_search): If we allocated a variable set for
606 an impossible file, free it.
607 * variable.c (free_variable_set): New function.
608 * variable.h: Declare it.
609
610 * read.c (read_all_makefiles): Makefile names are kept in the
611 strcache, so there's never any need to alloc/free them.
612 (eval): Ditto.
613
614 * main.c (main): Add "archives" to the .FEATURES variable if
615 archive support is enabled.
616 * doc/make.texi (Special Variables): Document it.
617
6182006-02-13 Paul D. Smith <psmith@gnu.org>
619
620 * implicit.c (pattern_search): Add checking for DOS pathnames to
621 the pattern rule target LASTSLASH manipulation.
622 Fixes Savannah bug #11183.
623
6242006-02-11 Paul D. Smith <psmith@gnu.org>
625
626 * (ALL FILES): Updated copyright and license notices.
627
6282006-02-10 Paul D. Smith <psmith@gnu.org>
629
630 A new internal capability: the string cache is a read-only cache
631 of strings, with a hash table interface for fast lookup. Nothing
632 in the cache will ever be freed, so there's no need for reference
633 counting, etc. This is the beginning of a full solution for
634 Savannah bug #15182, but for now we only store makefile names here.
635
636 * strcache.c: New file. Implement a read-only string cache.
637 * make.h: Add prototypes for new functions.
638 * main.c (initialize_global_hash_tables): Initialize the string cache.
639 (print_data_base): Print string cache stats.
640 * read.c (eval_makefile): Use the string cache to store makefile
641 names. Rewrite the string allocation to be sure we free everything.
642
6432006-02-10 Eli Zaretskii <eliz@gnu.org>
644
645 * dir.c (dir_contents_file_exists_p): Don't opendir if the
646 directory time stamp didn't change, except on FAT filesystems.
647 Suggested by J. David Bryan <jdbryan@acm.org>.
648
6492006-02-09 Paul D. Smith <psmith@gnu.org>
650
651 * function.c (func_or): Implement a short-circuiting OR function.
652 (func_and): Implement a short-circuiting AND function.
653 (function_table_init): Update the table with the new functions.
654 * doc/make.texi (Conditional Functions): Changed the "if" section
655 to one on general conditional functions. Added documentation for
656 $(and ...) and $(or ...) functions.
657 * NEWS: Note new $(and ...) and $(or ...) functions.
658
6592006-02-08 Boris Kolpackov <boris@kolpackov.net>
660
661 * job.h (struct child): Add the dontcare bitfield.
662 * job.c (new_job): Cache dontcare flag.
663 * job.c (reap_children): Use cached dontcare flag instead of the
664 one in struct file. Fixes Savannah bug #15641.
665
6662006-02-06 Paul D. Smith <psmith@gnu.org>
667
668 * vpath.c (selective_vpath_search): If the file we find has a
669 timestamp from -o or -W, use that instead of the real time.
670 * remake.c (f_mtime): If the mtime is a special token from -o or
671 -W, don't overwrite it with the real mtime.
672 Fixes Savannah bug #15341.
673
674 Updates from Markus Mauhart <qwe123@chello.at>:
675
676 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
677 (process_signal, process_last_err, process_exit_code): Manage
678 invalid handle values.
679 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
680 manage invalid handles; remove them.
681 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
682 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
683 * README.cvs: Updates for building from CVS.
684
6852006-02-05 Paul D. Smith <psmith@gnu.org>
686
687 * file.c (enter_file): Keep track of the last double_colon entry,
688 to avoid walking the list every time we want to add a new one.
689 Fixes Savannah bug #15533.
690 * filedef.h (struct file): Add a new LAST pointer.
691
692 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
693 the comparison. For 64-bits systems the result of the subtraction
694 might not fit into an int. Use comparison instead.
695 Fixes Savannah bug #15534.
696
697 * doc/make.texi: Update the chapter on writing commands to reflect
698 the changes made in 3.81 for backslash/newline and SHELL handling.
699
7002006-02-01 Paul D. Smith <psmith@gnu.org>
701
702 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
703 variable st is not used when it's not initialized.
704 Patch from Eli Zaretskii <eliz@gnu.org>.

712 * make_msvc_net2003.vcproj [WINDOWS32]: New version from
713 J. Grant <jg@jguk.org>.
714
715 * main.c: Update the copyright year in the version output.
716 * prepare_w32.bat: Remove this file from the distribution.
717
7182006-01-21 Eli Zaretskii <eliz@gnu.org>
719
720 * remake.c (update_goal_chain): Set g->changed instead of
721 incrementing it, as it is only 8-bit wide, and could overflow if
722 many commands got started in update_file.
723
724 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
725
726 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
727 MAXIMUM_WAIT_OBJECTS.
728 (process_wait_for_any_private): Change dimension of handles[]
729 array to MAXIMUM_WAIT_OBJECTS.
730 (process_used_slots): New function.
731 (process_register): Don't register more processes than the
732 available number of slots.
733 (process_easy): Don't start new processes if all slots are used up.
734
735 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
736 are already more children than sub_proc.c can handle, behave as if
737 the load were too high.
738 (start_job_command): Fix a typo in error message when process_easy
739 fails.
740
7412006-01-14 Eli Zaretskii <eliz@gnu.org>
742
743 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
744 the shell is not sh.exe.
745
746 * job.c (create_batch_file): Renamed from create_batch_filename;
747 all callers changed. Don't close the temporary file; return its
748 file descriptor instead. New arg FD allows to return the file
749 descriptor.
750 (construct_command_argv_internal): Use _fdopen instead of fopen to
751 open the batch file.
752
7532006-01-04 Paul D. Smith <psmith@gnu.org>
754
755 * readme.vms: Updates for case-insensitive VMS file systems from
756 Hartmut Becker <Hartmut.Becker@hp.com>.
757 * dir.c (vms_hash): Ditto.

764
7652006-01-03 Paul D. Smith <psmith@gnu.org>
766
767 * remake.c (update_file_1): Mark a prerequisite changed if it
768 doesn't exist.
769
770 * read.c (eval): Be sure to strip off trailing whitespace from the
771 prerequisites list properly. Also, initialize all fields in
772 struct dep when creating a new one.
773
7742005-12-28 Paul D. Smith <psmith@gnu.org>
775
776 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
777 disable warnings for MSC.
778 Patch by Rob Tulloh <rtulloh@yahoo.com>.
779
7802005-12-17 Eli Zaretskii <eliz@gnu.org>
781
782 * doc/make.texi (Execution): Add a footnote about changes in
783 handling of backslash-newline sequences. Mention the differences
784 on MS-DOS and MS-Windows.
785
786 * NEWS: More details about building the MinGW port and a pointer
787 to README.W32. Fix the section name that describes the new
788 backward-incompatible processing of backslash-newline sequences.
789 The special processing of SHELL set to "cmd" is only relevant to
790 MS-Windows, not MS-DOS.
791
7922005-12-17 Eli Zaretskii <eliz@gnu.org>
793
794 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
795 to DWORD, to avoid compiler warnings.
796 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
797 use %ld in format, to avoid compiler warnings.
798
799 * doc/make.texi (Special Targets): Fix a typo.
800 (Appending): Fix cross-reference to Setting.
801 (Special Variables, Secondary Expansion, File Name Functions)
802 (Flavor Function, Pattern Match, Quick Reference): Ensure two
803 periods after a sentence.
804 (Execution): Add @: after "e.g.".
805 (Environment): Fix punctuation.
806 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
807 (Shell Function, Target-specific): Add @: after "vs."
808
8092005-12-14 Boris Kolpackov <boris@kolpackov.net>
810
811 * read.c (record_target_var): Initialize variable's export field
812 with v_default instead of leaving it "initialized" by whatever
813 garbage happened to be on the heap.
814
8152005-12-12 Paul D. Smith <psmith@gnu.org>
816
817 * make.1: Fix some display errors and document all existing options.
818 Patch provided by Mike Frysinger <vapier@gentoo.org>.
819
8202005-12-11 Paul D. Smith <psmith@gnu.org>
821
822 * implicit.c (pattern_search): If 2nd expansion is not set for
823 this implicit rule, replace the pattern with the stem directly,
824 and don't re-expand the variable list. Along with the other
825 .SECONDEXPANSION changes below, fixes bug #13781.
826
8272005-12-09 Boris Kolpackov <boris@kolpackov.net>
828
829 * implicit.c (pattern_search): Mark other files that this rule
830 builds as targets so that they are not treated as intermediates
831 by the pattern rule search algorithm. Fixes bug #13022.
832
8332005-12-07 Boris Kolpackov <boris@kolpackov.net>
834
835 * remake.c (notice_finished_file): Propagate the change of
836 modification time to all the double-colon entries only if
837 it is the last one to be updated. Fixes bug #14334.
838
8392005-11-17 Boris Kolpackov <boris@kolpackov.net>
840
841 * function.c (func_flavor): Implement the flavor function which
842 returns the flavor of a variable.
843 * doc/make.texi (Functions for Transforming Text): Document it.
844 * NEWS: Add it to the list of new functions.
845
8462005-11-14 Boris Kolpackov <boris@kolpackov.net>
847
848 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
849 variable.
850 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.

854
855 * read.c (record_files): Don't set deps flags if there are no deps.
856 * maintMakefile: We only need to build the templates when we are
857 creating a distribution, so don't do it for "all".
858
8592005-10-24 Paul D. Smith <psmith@gnu.org>
860
861 Make secondary expansion optional: its enabled by declaring the
862 special target .SECONDEXPANSION.
863
864 * NEWS: Update information on second expansion capabilities.
865 * doc/make.texi (Secondary Expansion): Document the
866 .SECONDEXPANSION special target and its behavior.
867 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
868 prerequisite list was found in a static pattern rule.
869 (free_dep_chain): Declare a prototype.
870 * file.c (parse_prereqs): New function: break out some complexity
871 from expand_deps().
872 (expand_deps): If we aren't doing second expansion, replace % with
873 the stem for static pattern rules. Call the new function.
874 * filedef.h (parse_prereqs): Declare a prototype.
875 * implicit.c (pattern_search): Initialize the new staticpattern
876 field.
877 * main.c (second_expansion): Declare a global variable to remember
878 if the special target has been seen. Initialize the new
879 staticpattern field for prerequisites.
880 * make.h: Extern for second_expansion.
881 * misc.c (free_dep_chain): New function: frees a struct dep list.
882 * read.c (read_all_makefiles): Initialize the staticpattern field.
883 (eval_makefile): Ditto.
884 (record_files): Check for the .SECONDEXPANSION target and set
885 second_expansion global if it's found.
886 Use the new free_dep_chain() instead of doing it by hand.
887 Set the staticpattern field for prereqs of static pattern targets.
888
8892005-10-16 Paul D. Smith <psmith@gnu.org>
890
891 * main.c (main): Set CURDIR to be a file variable instead of a
892 default, so that values of CURDIR inherited from the environment
893 won't override the make value.
894
8952005-09-26 Paul D. Smith <psmith@gnu.org>
896
897 * job.c (construct_command_argv_internal): If the line is empty
898 remember to free the temporary argv strings.
899 Fixes bug # 14527.
900
9012005-09-16 Paul D. Smith <psmith@gnu.org>
902
903 * job.c (start_job_command): The noerror flag is a boolean (single
904 bit); set it appropriately.
905 Reported by Mark Eichin <eichin@metacarta.com>
906
9072005-08-29 Paul D. Smith <psmith@gnu.org>
908
909 * function.c (func_error): On Windows, output from $(info ...)
910 seems to come in the wrong order. Try to force it with fflush().
911
9122005-08-10 Boris Kolpackov <boris@kolpackov.net>
913
914 * read.c (record_files): Move code that sets stem for static
915 pattern rules out of the if (!two_colon) condition so it is
916 also executed for two-colon rules. Fixes Savannah bug #13881.
917
9182005-08-08 Paul D. Smith <psmith@gnu.org>
919
920 * make.h: Don't test that __STDC__ is non-0. Some compilers
921 (Windows for example) set it to 0 to denote "ISO C + extensions".
922 Fixes bug # 13594.
923
9242005-08-07 Paul D. Smith <psmith@gnu.org>
925
926 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
927 conditional (slightly different version of a fix from Eli).
928
929 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
930 If make is running in parallel without -k and two jobs die in a
931 row, but not too close to each other, then make will quit without
932 waiting for the rest of the jobs to die.
933
934 * main.c (die): Don't reset err before calling reap_children() the
935 second time: we still want it to be in the error condition.
936 * job.c (reap_children): Use a static variable, rather than err,
937 to control whether or not the error message should be printed.
938
9392005-08-06 Eli Zaretskii <eliz@gnu.org>
940
941 * w32/subproc/sub_proc.c: Include signal.h.
942 (process_pipe_io, process_file_io): Pass a pointer to a local
943 DWORD variable to GetExitCodeProcess. If the exit code is
944 CONTROL_C_EXIT, put SIGINT into pproc->signal.
945
946 * job.c [WINDOWS32]: Include windows.h.
947 (main_thread) [WINDOWS32]: New global variable.
948 (reap_children) [WINDOWS32]: Get the handle for the main thread
949 and store it in main_thread.
950
951 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
952 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
953 doing anything else. When we are done, close the main thread
954 handle and exit with status 130.
955
9562005-07-30 Eli Zaretskii <eliz@gnu.org>
957
958 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
959 pointer to fprintf.
960
961 * main.c (find_and_set_default_shell): If found a DOSish shell,
962 set sh_found and the value of default_shell, and report the
963 findings in debug mode.
964
965 * job.c (construct_command_argv_internal): Check unixy_shell, not

9932005-07-30 J. Grant <jg@jguk.org>
994
995 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.

9992005-07-15 Paul Smith <psmith@gnu.org>
1000
1001 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1002 we don't have a POSIX shell, then revert to the old
1003 backslash-newline behavior (where they are stripped).
1004 Fixes bug #13665.
1005
10062005-07-08 Paul D. Smith <psmith@gnu.org>
1007
1008 * config.h.W32.template: Reorder to match the standard config.h,
1009 for easier comparisons.
1010 From J. Grant <jg@jguk.org>
1011
1012 * maintMakefile: Remove .dep_segment before overwriting it, in
1013 case it's not writable or noclobber is set.
1014 * expand.c (variable_expand_string): Cast result of pointer
1015 arithmetic to avoid a warning.
1016 * main.c (switches): Add full-fledged final initializer.
1017
10182005-07-06 Paul D. Smith <psmith@gnu.org>
1019
1020 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1021 * signame.c (strsignal): If we found _sys_siglist[] or
1022 __sys_siglist[] use those instead of sys_siglist[].
1023 From Albert Chin <china@thewrittenword.com>
1024
10252005-07-04 Paul D. Smith <psmith@gnu.org>
1026
1027 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1028 globfree(); set up to use the GNU versions.
1029 From Martin Zinser <zinser@zinser.no-ip.info>
1030
10312005-07-03 Paul D. Smith <psmith@gnu.org>
1032
1033 From J. Grant <jg@jguk.org>:
1034
1035 * README.W32.template: Update the Windows and tested MSVC versions.
1036 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1037 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1038 * build_w32.bat: Ditto.
1039 * w32/subproc/build.bat: Ditto.
1040
10412005-06-28 Paul D. Smith <psmith@gnu.org>
1042
1043 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1044 declaration was checked but not present.
1045
10462005-06-27 Paul D. Smith <psmith@gnu.org>
1047
1048 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1049 to unsigned long. Fixes Savannah bug #13550.
1050
1051 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1052 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1053 Fixes Savannah bug #13551.
1054
10552005-06-26 Paul D. Smith <psmith@gnu.org>
1056
1057 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1058 it if ANSI_STRING is not set.
1059
10602005-06-25 Paul D. Smith <psmith@gnu.org>
1061
1062 * read.c (eval): If no filenames are passed to any of the
1063 "include" variants, don't print an error.
1064 * doc/make.texi (Include): Document this.
1065 Fixes Savannah bug #1761.
1066
1067 * job.c (construct_command_argv_internal): Sanitize handling of
1068 backslash/newline pairs according to POSIX: that is, keep the
1069 backslash-newline in the command script, but remove a following
1070 TAB character, if present. In the fast path, make sure that the
1071 behavior matches what the shell would do both inside and outside
1072 of quotes. In the slow path, quote the backslash and put a
1073 literal newline in the string.
1074 Fixes Savannah bug #1332.
1075 * doc/make.texi (Execution): Document the new behavior and give
1076 some examples.
1077 * NEWS: Make a note of the new behavior.
1078
1079 * make.h [WINDOWS32]: #include <direct.h>.
1080 Fixes Savannah bug #13478.
1081
1082 * remake.c (name_mtime): If the stat() of a file fails and the -L
1083 option was given and the file is a symlink, take the best mtime of
1084 the symlink we can get as the mtime of the file and don't fail.
1085 Fixes Savannah bug #13280.
1086
1087 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1088 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1089 inside a variable reference. Make this function static as it's
1090 only used here.
1091 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1092 parsing an unexpanded line looking for semicolons.
1093 Fixes Savannah bug #1454.
1094 * misc.c (remove_comments): Move this to read.c and make it static
1095 as it's only used there. Call find_char_unquote() with new arg.
1096 * make.h: Remove prototypes for find_char_unquote() and
1097 remove_comments() since they're static now.
1098
1099 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1100 its export flag and obtain its value. When we need to re-exec,
1101 increment the value and add it into the environment.
1102 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1103 * NEWS: Mention MAKE_RESTARTS.
1104 * main.c (always_make_set): New variable. Change the -B option to
1105 set this one instead.
1106 (main): When checking makefiles, only set always_make_flag if
1107 always_make_set is set AND the restarts flag is 0. When building
1108 normal targets, set it IFF always_make_set is set.
1109 (main): Avoid infinite recursion with -W, too: only set what-if
1110 files to NEW before we check makefiles if we've never restarted
1111 before. If we have restarted, set what-if files to NEW _after_ we
1112 check makefiles.
1113 Fixes Savannah bug #7566:
1114
11152005-06-17 Paul D. Smith <psmith@gnu.org>
1116
1117 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1118 in the prerequisites list.
1119
11202005-06-12 Paul D. Smith <psmith@gnu.org>
1121
1122 Fix Savannah bug # 1328.
1123
1124 * configure.in: Check for atexit().
1125 * misc.c (close_stdout): Test stdout to see if writes to it have
1126 failed. If so, be sure to exit with a non-0 error code. Based on
1127 code found in gnulib.
1128 * make.h: Prototype.
1129 * main.c (main): Install close_stdout() with atexit().
1130
11312005-06-10 Paul D. Smith <psmith@gnu.org>
1132
1133 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1134
1135 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1136 headers; make vmsWaitForChildren() static; extern vmsify().
1137 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1138 Don't create child_execute_job() here (it's in vmsjobs.c).
1139 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1140
11412005-06-09 Paul D. Smith <psmith@gnu.org>
1142
1143 * variable.c (push_new_variable_scope): File variables point
1144 directly to the global_setlist variable. So, inserting a new
1145 scope in front of that has no effect on those variables: they
1146 don't go through current_variable_set_list. If we're pushing a
1147 scope and the current scope is global, push it "the other way" so
1148 that the new setlist is in the global_setlist variable, and
1149 next points to a new setlist with the global variable set.
1150 (pop_variable_scope): Properly undo a push with the new
1151 semantics.
1152 Fixes Savannah bug #11913.
1153
11542005-05-31 Boris Kolpackov <boris@kolpackov.net>
1155
1156 * job.c (reap_children): Don't die of the command failed but
1157 the dontcare flag is set. Fixes Savannah bug #13216.
1158
1159 * implicit.c (pattern_search): When creating a target from
1160 an implicit rule match, lookup pattern target and set precious
1161 flag in a newly created target. Fixes Savannah bug #13218.
1162
11632005-05-13 Paul D. Smith <psmith@gnu.org>
1164
1165 Implement "if... else if... endif" syntax.
1166
1167 * read.c (eval): Push all checks for conditional words ("ifeq",
1168 "else", etc.) down into the conditional_line() function.
1169 (conditional_line): Rework to allow "else if..." clause. New
1170 return value -2 for lines which are not conditionals. The
1171 ignoring flag can now also be 2, which means "already parsed a
1172 true branch". If that value is seen no other branch of this
1173 conditional can be considered true. In the else parsing if there
1174 is extra text after the else, invoke conditional_line()
1175 recursively to see if it's another conditional. If not, it's an
1176 error. If so, raise the conditional value to this level instead
1177 of creating a new conditional nesting level. Special check for
1178 "else" and "endif", which aren't allowed on the "else" line.
1179 * doc/make.texi (Conditional Syntax): Document the new syntax.
1180
11812005-05-09 Paul D. Smith <psmith@gnu.org>
1182
1183 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1184 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1185 recurses to the w32 directory, even on non-Windows systems. Use
1186 the method suggested in the automake manual.
1187 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1188 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1189
11902005-05-07 Paul D. Smith <psmith@gnu.org>
1191
1192 * main.c (die): If we're dying with a fatal error (not that a
1193 command has failed), write back any leftover tokens before we go.
1194
1195 * job.c (set_child_handler_action_flags): If there are jobs
1196 waiting for the load to go down, set an alarm to go off in 1
1197 second. This allows us to wake up from a potentially long-lasting
1198 read() and start a new job if the load has gone down. Turn it off
1199 after the read.
1200 (job_noop): Dummy signal handler function.
1201 (new_job): Invoke it with the new semantics.
1202
1203 * docs/make.texi: Document secondary expansion. Various cleanups
1204 and random work.
1205
12062005-05-03 Paul D. Smith <psmith@gnu.org>
1207
1208 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1209 the targets which are to ultimately be made are called "goals";
1210 see the GNU make manual. Also, MAKECMDGOALS, etc.
1211
1212 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1213 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1214 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1215
12162005-05-02 Paul D. Smith <psmith@gnu.org>
1217
1218 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1219 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1220 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1221 functions to vmsjobs.c. #include it into jobs.c.
1222
1223 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1224 jobserver tokens. I found that this happens when an exported
1225 recursive variable contains a $(shell ...) function reference: in
1226 this situation we could "forget" to write back a token.
1227
1228 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1229 we have. It's not reliable to depend on the number of children in
1230 our linked list so keep a separate count.
1231 (new_job): Check jobserver_tokens rather than children &&
1232 waiting_jobs. Increment jobserver_tokens when we get one.
1233 (free_child): If jobserver_tokens is 0, internal error. If it's
1234 >1, write a token back to the jobserver pipe (we don't write a
1235 token for the "free" job). Decrement jobserver_tokens.
1236
1237 * main.c: Add variable master_job_slots.
1238 (main): Set it to hold the number of jobs requested if we're the
1239 master process, when using the jobserver.
1240 (die): Sanity checks: first test jobserver_tokens to make sure
1241 this process isn't holding any tokens we didn't write back.
1242 Second, if master_job_slots is set count the tokens left in the
1243 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1244
12452005-04-24 Paul D. Smith <psmith@gnu.org>
1246
1247 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1248 with -l# can lose jobserver tokens, because waiting jobs are not
1249 consulted properly when checking for the "free" token.
1250
1251 * job.c (free_child): Count waiting_jobs as having tokens.
1252 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1253 handle jobs waiting for the load to drop.
1254
12552005-04-23 Paul D. Smith <psmith@gnu.org>
1256
1257 * main.c (main): Be careful to not core if a variable setting in
1258 the environment doesn't contain an '='. This is illegal but can
1259 happen in broken setups.
1260 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1261
12622005-04-12 Paul D. Smith <psmith@gnu.org>
1263
1264 The second expansion feature causes significant slowdown. Timing
1265 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1266 read the makefile before the feature, to 11+s to do the same
1267 operations after the feature. Additionally, memory usage
1268 increased drastically. To fix this I added some intelligence that
1269 avoids the overhead of the second expansion unless it's required.
1270
1271 * dep.h: Add a new boolean field, need_2nd_expansion.
1272
1273 * read.c (eval): When creating the struct dep for the target,
1274 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1275 (record_files): If there's a "%" in a static pattern rule, it gets
1276 converted to "$*" so set need_2nd_expansion to 1.
1277
1278 * file.c (expand_deps): Rework to be more efficient. Only perform
1279 initialize_file_variables(), set_file_variables(), and
1280 variable_expand_for_file() if the need_2nd_expansion is set.
1281
1282 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1283 (pattern_search): Ditto.
1284 * main.c (handle_non_switch_argument): Ditto.
1285 (main): Ditto.
1286 * read.c (read_all_makefiles): Ditto.
1287 (eval_makefile): Ditto.
1288
12892005-04-07 Paul D. Smith <psmith@gnu.org>
1290
1291 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1292 * variable.c (sync_Path_environment): Ditto.
1293 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1294
1295 * main.c (main): Define the .FEATURES variable.
1296 * NEWS: Announce .FEATURES.
1297 * doc/make.texi (Special Variables): Document .FEATURES.
1298
1299 * remake.c (check_dep): If a file is .PHONY, update it even if
1300 it's marked intermediate. Fixes Savannah bug #12331.
1301
13022005-03-15 Boris Kolpackov <boris@kolpackov.net>
1303
1304 * file.c (expand_deps): Factor out the second expansion and
1305 prerequisite line parsing logic from snap_deps().
1306
1307 * file.c (snap_deps): Use expand_deps(). Expand and parse
1308 prerequisites of the .SUFFIXES special target first. Fixes
1309 Savannah bug #12320.
1310
13112005-03-13 Paul D. Smith <psmith@gnu.org>
1312
1313 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1314 Zaretskii.
1315
13162005-03-11 Paul D. Smith <psmith@gnu.org>
1317
1318 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1319 available, not undefined (from Earnie Boyd).
1320
13212005-03-10 Boris Kolpackov <boris@kolpackov.net>
1322
1323 * implicit.c (pattern_search): Mark an intermediate target as
1324 precious if it happened to be a prerequisite of some (other)
1325 target. Fixes Savannah bug #12267.
1326
13272005-03-09 Paul D. Smith <psmith@gnu.org>
1328
1329 * read.c (eval_makefile): Add alloca(0).
1330 (eval_buffer): Ditto.
1331
13322005-03-09 Boris Kolpackov <boris@kolpackov.net>
1333
1334 * main.c (main): Use o_file instead of o_default when defining
1335 the .DEFAULT_TARGET special variable.
1336 * read.c (eval): Use define_variable_global() instead of
1337 define_variable() when setting new value for the .DEFAULT_TARGET
1338 special variable. Fixes Savannah bug #12266.
1339
13402005-03-04 Boris Kolpackov <boris@kolpackov.net>
1341
1342 * imlicit.c (pattern_search): Mark files for which an implicit
1343 rule has been found as targets. Fixes Savannah bug #12202.
1344
13452005-03-04 Paul D. Smith <psmith@gnu.org>
1346
1347 * AUTHORS: Update.
1348 * doc/make.texi (Automatic Variables): Document $|.
1349
13502005-03-03 Boris Kolpackov <boris@kolpackov.net>
1351
1352 * read.c (record_files): Instead of substituting % with
1353 actual stem value in dependency list replace it with $*.
1354 This fixes stem triple expansion bug.
1355
1356 * implicit.c (pattern_search): Copy stem to a separate
1357 buffer and make it a properly terminated string. Assign
1358 this buffer instead of STEM (which is not terminated) to
1359 f->stem. Instead of substituting % with actual stem value
1360 in dependency list replace it with $*. This fixes stem
1361 triple expansion bug.
1362
13632005-03-01 Paul D. Smith <psmith@gnu.org>
1364
1365 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1366 on Windows, as it takes a handle not a pid. Just exit.
1367 Fix from patch #3679, provided by Alessandro Vesely.
1368
1369 * configure.in: Update check for sys_siglist[] from autoconf manual.
1370 * signame.c (strsignal): Update to use the new autoconf macro.
1371
13722005-03-01 Boris Kolpackov <boris@kolpackov.net>
1373
1374 * read.c (record_files): Add a check for the list of prerequisites
1375 of a static pattern rule being empty. Fixes Savannah bug #12180.
1376
13772005-02-28 Paul D. Smith <psmith@gnu.org>
1378
1379 * doc/make.texi (Text Functions): Update docs to allow the end
1380 ordinal for $(wordlist ...) to be 0.
1381 * function.c (func_wordlist): Fail if the start ordinal for
1382 $(wordlist ...) is <1. Matches documentation.
1383 Resolves Savannah support request #103195.
1384
1385 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1386 previously we were stopping when !-q, exactly the opposite. This
1387 has been wrong since version 1.34, in 1994!
1388 (update_file): If we got an error don't break out to run more
1389 double-colon rules: just return immediately.
1390 Fixes Savannah bug #7144.
1391
13922005-02-27 Paul D. Smith <psmith@gnu.org>
1393
1394 * misc.c (end_of_token): Make argument const.
1395 * make.h: Update prototype.
1396
1397 * function.c (abspath, func_realpath, func_abspath): Use
1398 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1399 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1400 * read.c (record_files): Ditto.
1401 * variable.c (do_variable_definition): Ditto.
1402
1403 * function.c (func_error): Create a new function $(info ...) that
1404 simply prints the message to stdout with no extras.
1405 (function_table_init): Add new function to the table.
1406 * NEWS: Add $(info ...) reference.
1407 * doc/make.texi (Make Control Functions): Document it.
1408
1409 New feature: if the system supports symbolic links, and the user
1410 provides the -L/--check-symlink-time flag, then use the latest
1411 mtime between the symlink(s) and the target file.
1412
1413 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1414 readlink(). If both are available, define MAKE_SYMLINKS.
1415 * main.c: New variable: check_symlink_flag.
1416 (usage): Add a line for -L/--check-symlink-times to the help string.
1417 (switches): Add -L/--check-symlink-times command line argument.
1418 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1419 print a warning and disable it again.
1420 * make.h: Declare check_symlink_flag.
1421 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1422 if the file is a symlink then check each link in the chain and
1423 choose the NEWEST mtime we find as the mtime for the file. The
1424 newest mtime might be the file itself!
1425 * NEWS: Add information about this new feature.
1426 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1427
1428 Avoid core dumps described in Savannah bug # 12124:
1429
1430 * file.c: New variable snapped_deps remember whether we've run
1431 snap_deps().
1432 (snap_deps): Set it.
1433 * filedef.h: Extern it.
1434 * read.c (record_files): Check snapped_deps; if it's set then
1435 we're trying to eval a new target/prerequisite relationship from
1436 within a command script, which we don't support. Fatal.
1437
14382005-02-28 Boris Kolpackov <boris@kolpackov.net>
1439
1440 Implementation of the .DEFAULT_TARGET special variable.
1441
1442 * read.c (eval): If necessary, update default_target_name when
1443 reading rules.
1444 * read.c (record_files): Update default_target_file if
1445 default_target_name has changed.
1446 * main.c (default_target_name): Define.
1447 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1448 default_target_name is set use default_target_file as a root
1449 target to make.
1450 * filedef.h (default_target_name): Declare.
1451 * dep.h (free_dep_chain):
1452 * misc.c (free_dep_chain): Change to operate on struct nameseq
1453 and change name to free_ns_chain.
1454 * file.c (snap_deps): Update to use free_ns_chain.
1455
14562005-02-27 Boris Kolpackov <boris@kolpackov.net>
1457
1458 Implementation of the second expansion in explicit rules,
1459 static pattern rules and implicit rules.
1460
1461 * read.c (eval): Refrain from chopping up rule's dependencies.
1462 Store them in a struct dep as a single dependency line. Remove
1463 the code that implements SySV-style automatic variables.
1464
1465 * read.c (record_files): Adjust the code that handles static
1466 pattern rules to expand all percents instead of only the first
1467 one. Reverse the order in which dependencies are stored so that
1468 when the second expansion reverses them again they appear in
1469 the makefile order (with some exceptions, see comments in
1470 the code). Remove the code that implements SySV-style automatic
1471 variables.
1472
1473 * file.c (snap_deps): Implement the second expansion and chopping
1474 of dependency lines for explicit rules.
1475
1476 * implicit.c (struct idep): Define an auxiliary data type to hold
1477 implicit rule's dependencies after stem substitution and
1478 expansion.
1479
1480 * implicit.c (free_idep_chain): Implement.
1481
1482 * implicit.c (get_next_word): Implement helper function for
1483 parsing implicit rule's dependency lines into words taking
1484 into account variable expansion requests. Used in the stem
1485 splitting code.
1486
1487 * implicit.c (pattern_search): Implement the second expansion
1488 for implicit rules. Also fixes bug #12091.
1489
1490 * commands.h (set_file_variables): Declare.
1491 * commands.c (set_file_variables): Remove static specifier.
1492
1493 * dep.h (free_dep_chain): Declare.
1494 * misc.c (free_dep_chain): Implement.
1495
1496 * variable.h (variable_expand_for_file): Declare.
1497 * expand.c (variable_expand_for_file): Remove static specifier.
1498
1499 * make.h (strip_whitespace): Declare.
1500 * function.c (strip_whitespace): Remove static specifier.
1501
15022005-02-26 Paul D. Smith <psmith@gnu.org>
1503
1504 * main.c (main): Check for ferror() when reading makefiles from stdin.
1505 Apparently some shells in Windows don't close pipes properly and
1506 require this check.
1507
15082005-02-24 Jonathan Grant <jg@jguk.org>
1509
1510 * configure.in: Add MinGW configuration options, and extra w32 code
1511 directory.
1512 * Makefile.am: Add MinGW configuration options, and extra w32 code
1513 directory.
1514 * main.c: Determine correct program string (after last \ without .exe).
1515 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1516 type fix x2
1517 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1518 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1519 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1520 environment support.
1521
15222004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1523
1524 * function.c (func_shell): When initializing error_prefix, check
1525 that reading file name is not null. This fixes long-standing
1526 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1527
15282005-02-09 Paul D. Smith <psmith@gnu.org>
1529
1530 * maintMakefile: Update the CVS download URL to simplify them.
1531 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1532 downloading the .texi files from Savannah now.
1533
1534 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1535
1536 * main.c (handle_non_switch_argument): Only add variables to
1537 command_variables if they're not already there: duplicate settings
1538 waste space and can be confusing to read.
1539
1540 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1541 this header is never included by non-WINDOWS32 code, and it
1542 requires <config.h> to define which isn't always included first.
1543
1544 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1545 testing MINGW32 versions.
1546
1547 * main.c (log_working_directory): flush stdout to be sure the WD
1548 change is printed before any stderr messages show up.
1549
15502005-02-01 Paul D. Smith <psmith@gnu.org>
1551
1552 * maintMakefile (po_repo): Update the GNU translation site URL.
1553
15542004-12-01 Paul D. Smith <psmith@gnu.org>
1555
1556 * main.c (main): Change char* env_shell to struct variable shell_var.
1557 * variable.c (target_environment): Use new shell_var.
1558
15592004-11-30 Paul D. Smith <psmith@gnu.org>
1560
1561 * configure.in: The old way we avoided creating build.sh from
1562 build.sh.in before build.sh.in exists doesn't work anymore; we
1563 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1564 the help!). This also keeps automake from complaining.
1565 * Makefile.am (README): Add a dummy target so automake won't
1566 complain that this file doesn't exist when we checkout from CVS.
1567 * maintMakefile (.dep_segment): Rewrite this rule since newer
1568 versions of automake don't provide DEP_FILES.
1569
15702004-11-30 Boris Kolpackov <boris@kolpackov.net>
1571
1572 Implementation of `realpath' and `abspath' built-in functions.
1573
1574 * configure.in: Check for realpath.
1575 * function.c (abspath): Return an absolute file name that does
1576 not contain any `.' or `..' components, nor repeated `/'.
1577 * function.c (func_abspath): For each name call abspath.
1578 * function.c (func_realpath): For each name call realpath
1579 from libc or delegate to abspath if realpath is not available.
1580 * doc/make.texi (Functions for File Names): Document new functions.
1581 * doc/make.texi (Quick Reference): Ditto.
1582
15832004-11-28 Paul D. Smith <psmith@gnu.org>
1584
1585 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1586 arguments. Fixes bug #10252.
1587
1588 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1589
1590 * main.c (main): Set SHELL to v_noexport by default. Remember the
1591 original environment setting of SHELL in the env_shell variable.
1592 * main.h: Export new env_shell variable.
1593 * variable.c (target_environment): If we find a v_noexport
1594 variable for SHELL, add a SHELL variable with the env_shell value.
1595 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1596 * doc/make.texi (Variables/Recursion): Ditto.
1597
15982004-11-28 Paul D. Smith <psmith@gnu.org>
1599
1600 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1601 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1602 Patch by Alessandro Vesely.
1603
16042004-11-12 Paul D. Smith <psmith@gnu.org>
1605
1606 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1607 the command line if it's inside a string.
1608 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1609
16102004-10-21 Boris Kolpackov <boris@kolpackov.net>
1611
1612 * function.c (func_lastword): New function: return last word
1613 from the list of words.
1614 * doc/make.texi: Document $(lastword ). Fix broken links in
1615 Quick Reference section.
1616
16172004-10-06 Paul D. Smith <psmith@gnu.org>
1618
1619 Apply patch from Alessandro Vesely, provided with bug # 9748.
1620 Fix use of tmpnam() to work with Borland C.
1621
1622 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1623 construction of a temporary filename, and call new function
1624 create_batch_filename().
1625 (create_batch_filename) [WINDOWS32]: New function to create a
1626 temporary filename.
1627
16282004-10-05 Boris Kolpackov <boris@kolpackov.net>
1629
1630 * read.c (record_target_var): Expand simple pattern-specific
1631 variable.
1632 * variable.c (initialize_file_variables): Do not expand simple
1633 pattern-specific variable.
1634
16352004-09-28 Boris Kolpackov <boris@kolpackov.net>
1636
1637 * remake.c (update_file_1): When rebuilding makefiles inherit
1638 dontcare flag from a target that triggered update.
1639
16402004-09-27 Boris Kolpackov <boris@kolpackov.net>
1641
1642 * variable.c (initialize_file_variables): Mark pattern-specific
1643 variable as a per-target and copy export status.
1644
16452004-09-21 Boris Kolpackov <boris@kolpackov.net>
1646
1647 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1648
1649 * implicit.c (pattern_search): When considering an implicit rule's
1650 prerequisite check that it is actually a target rather then
1651 just an entry in the file hashtable.
1652
16532004-09-21 Paul D. Smith <psmith@gnu.org>
1654
1655 * read.c (readstring): Fix some logic errors in backslash handling.
1656 (eval): Remove some unnecessary processing in buffer handling.
1657 (record_target_var): Assert that parse_variable_definition() succeeded.
1658 Reported by: Markus Mauhart <qwe123@chello.at>.
1659
1660 * misc.c: Removed the sindex() function. All instances of this
1661 function were trivially replaceable by the standard strstr()
1662 function, and that function will always have better (or certainly
1663 no worse) performance than the very simple-minded algorithm
1664 sindex() used. This can matter with complex makefiles.
1665 * make.h: Remove the prototype for sindex().
1666 * function.c (subst_expand): Convert sindex() call to strstr().
1667 This means we no longer need to track the TLEN value so remove that.
1668 (func_findstring): Convert sindex() to strstr().
1669 * commands.c (chop_commands): Convert sindex() calls to strstr().
1670 Suggested by: Markus Mauhart <qwe123@chello.at>.
1671
1672 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1673 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1674 If SHELL is set to CMD.EXE then assume it's batch-mode and
1675 non-unixy. I wrote the code differently from the patch, though,
1676 to make it safer. This also resolves bug #9174.
1677
16782004-09-20 Paul D. Smith <psmith@gnu.org>
1679
1680 * expand.c (variable_expand_string): Modify to invoke
1681 patsubst_expand() instead of subst_expand(); the latter didn't
1682 handle suffix patterns correctly.
1683 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1684 was used only from variable_expand_string() and is no longer used
1685 there.
1686 (func_subst): Ditto, on call to subst_expand().
1687 (patsubst_expand): Require the percent pointers to point to the
1688 character after the %, not to the % itself.
1689 * read.c (record_files): New call criteria for patsubst_expand().
1690 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1691 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1692
16932004-09-19 Paul D. Smith <psmith@gnu.org>
1694
1695 * function.c (subst_expand): Fix a check in by_word: look for a
1696 previous blank if we're beyond the beginning of the string, not
1697 the beginning of the word.
1698 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1699
17002004-05-16 Paul D. Smith <psmith@gnu.org>
1701
1702 * remake.c (update_goal_chain): Change the argument specifying
1703 whether we're rebuilding makefiles to be a global variable,
1704 REBUILDING_MAKEFILES.
1705 (complain): Extract the code that complains about no rules to make
1706 a target into a separate function.
1707 (update_file_1): If we tried to rebuild a file during the makefile
1708 rebuild phase and it was dontcare, then no message was printed.
1709 If we then try to build the same file during the normal build,
1710 print a message this time.
1711 (remake_file): Don't complain about un-remake-able files when
1712 we're rebuilding makefiles.
1713
17142004-05-11 Paul D. Smith <psmith@gnu.org>
1715
1716 * job.c (construct_command_argv_internal): OS/2 patches from
1717 Andreas Buening <andreas.buening@nexgo.de>.
1718
17192004-05-10 Paul D. Smith <psmith@gnu.org>
1720
1721 * remake.c (update_file): Don't walk the double-colon chain unless
1722 this is a double-colon rule. Fix suggested by Boris Kolpackov
1723 <boris@kolpackov.net>.
1724
1725 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1726 * readme.vms: New section describing OpenVMS support and issues.
1727 * default.c (default_variables): Add support for IA64.
1728 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1729 without some privilege aborts make with the error
1730 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1731 pressing Ctrl+Y and the input device is no terminal. The change
1732 catches this error and just continues.

1735
17362004-04-25 Paul D. Smith <psmith@gnu.org>
1737
1738 * commands.c (set_file_variables): Set $< properly in the face of
1739 order-only prerequisites.
1740 Patch from Boris Kolpackov <boris@kolpackov.net>
1741
17422004-04-21 Bob Byrnes <byrnes@curl.com>
1743
1744 * main.c (main): Notice failures to remake makefiles.

17462004-03-28 Paul D. Smith <psmith@gnu.org>
1747
1748 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1749
1750 * job.c: No default shell for RISC OS.
1751 (load_too_high): Hard-code the return to 1.
1752 (construct_command_argv_internal): No sh_chars or sh_cmds.
1753 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1754
17552004-03-20 Paul D. Smith <psmith@gnu.org>
1756
1757 * variable.c (do_variable_definition): Don't append from the
1758 global set if a previous non-appending target-specific variable
1759 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1760 (with fix).
1761
1762 * expand.c (reference_variable): Don't give up on variables with
1763 no value that have the target-specific append flag set: they might
1764 have a value after all. Reported by Oliver Schmidt
1765 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1766 <nikulin@dx1cmd.inp.nsk.su>.
1767
1768 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1769 refer to absolute pathnames in directories that don't exist: some
1770 portion of the makefile could create those directories before we
1771 match the pattern. Fixes bugs #775 and #108.
1772
1773 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1774
1775 * main.c (main): Free makefile_mtimes if we have any.
1776 * README.W32.template: Update documentation for the current status
1777 of the MS-Windows port.
1778 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1779 environment variable is sometimes already defined which causes the
1780 build to fail.
1781 * main.c (debug_signal_handler): Only define this function if
1782 SIGUSR1 is available.
1783
1784 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1785
1786 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1787 * README.OS2.template: Documentation updates.
1788 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1789 link line for safety.
1790 * maintMakefile (build.sh.in): Remove an extraneous ")".
1791 * job.c (child_execute_job): Close saved FDs.
1792 * job.c (exec_command) [OS/2]: exec_command(): If the command
1793 can't be exec'ed and if the shell is not Unix-sh, then try again
1794 with argv = { "cmd", "/c", ... }. Normally, this code is never
1795 reached for the cmd shell unless the command really doesn't exist.
1796 (construct_command_argv_internal) [OS/2]: The code for cmd
1797 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1798 The CMD builtin commands are case insensitive so use strcasecmp().
1799
18002004-03-19 Paul D. Smith <psmith@gnu.org>
1801
1802 * read.c (do_define): Re-order line counter increment so the count
1803 is accurate (we were losing one line per define). Reported by
1804 Dave Yost <Dave@Yost.com>.
1805
18062004-03-06 Paul D. Smith <psmith@gnu.org>
1807
1808 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1809 compiler.
1810 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1811 * misc.c (message,error,fatal): Ditto.
1812 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1813 * config.h.W32.template: Ditto.
1814 * config.h-vms.template: Ditto.
1815 * config.ami.template: Ditto.
1816
18172004-03-04 Paul D. Smith <psmith@gnu.org>
1818
1819 * README.template: Add a note about broken /bin/sh on SunOS
1820 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1821
1822 * misc.c (message, error, fatal): Don't use "..." if we're using
1823 varargs. ansi2knr should handle this but it doesn't work: it
1824 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1825 done. On many systems (SunOS for example) va_dcl is a #define.
1826 So, force the use of the non-"..." version on pre-ANSI compilers.
1827
1828 * maintMakefile (sign-dist): Create some rules to help automate
1829 the new GNU ftp upload method.
1830
18312004-02-24 Paul D. Smith <psmith@gnu.org>
1832
1833 * config.h.W32.template: Add HAVE_STDARG_H
1834 * config.h-vms.template: Ditto.
1835 * config.ami.template: Ditto.
1836
18372004-02-23 Jonathan Grant <jg-make@jguk.org>
1838
1839 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1840 * build_w32.bat: Remove extra "+".
1841
18422004-02-23 Paul D. Smith <psmith@gnu.org>
1843
1844 * make.h: Create an UNUSED macro to mark unused parameters.
1845 * (many): Clean up warnings by applying UNUSED, fixing
1846 signed/unsigned incompatibilities, etc.
1847
1848 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1849 autoconf warnings.
1850 * filedef.h: Name the command_state enumeration.
1851 * file.c (set_command_state): Use the enumeration in the function
1852 argument.
1853
1854 * configure.in: Explicitly set SET_MAKE to empty, to disable
1855 MAKE=make even when no make already exists. Fix bug #3823.
1856
18572004-02-22 Paul D. Smith <psmith@gnu.org>
1858
1859 * maintMakefile: Perl script to clean up all non-CVS files. Use
1860 it on all the subdirectories for the cvs-clean target.
1861
1862 * main.c (decode_switches): Require non-empty strings for all our
1863 string command-line options. Fixes Debian bug # 164165.
1864
1865 * configure.in: Check for stdarg.h and varargs.h.
1866 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1867 for printing messages.
1868 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1869 (message): Ditto.
1870 (error): Ditto.
1871 (fatal): Ditto.
1872
1873 A number of patches for OS/2 support from Andreas Buening
1874 <andreas.buening@nexgo.de>:
1875
1876 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1877 disable the SIGCHLD handler.
1878 (reap_children) [OS/2]: Remove special handling of job_rfd.
1879 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1880 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1881 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1882 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1883 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1884 systems.
1885
18862004-02-21 Paul D. Smith <psmith@gnu.org>
1887
1888 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1889 <mail@kristov.de> reports that if process_begin() fails we don't
1890 handle the error condition correctly in all cases.
1891 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1892 to have a newline on the message.
1893
1894 * job.c (construct_command_argv_internal): Add "test" to UNIX
1895 sh_cmds[]. Fixes Savannah bug # 7606.
1896
18972004-02-04 Paul D. Smith <psmith@gnu.org>
1898
1899 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1900 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1901 Hartmut Becker <Hartmut.Becker@hp.com>.
1902
19032004-01-21 Paul D. Smith <psmith@gnu.org>
1904
1905 * job.c (load_too_high): Implement an algorithm to control the
1906 "thundering herd" problem when using -l to control job creation
1907 via the load average. The system only recomputes the load once a
1908 second but we can start many jobs in a second. To solve this we
1909 keep track of the number of jobs started in the last second and
1910 apply a weight to try to guess what a correct load would be.
1911 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1912 Also fixes bug #4693.
1913 (reap_children): Decrease the job count for this second.
1914 (start_job_command): Increase the job count for this second.
1915
1916 * read.c (conditional_line): Expand the text after ifn?def before
1917 checking to see if it's a single word. Fixes bug #7257.
1918
19192004-01-09 Paul D. Smith <psmith@gnu.org>
1920
1921 * file.c (print_file): Recurse to print all targets in
1922 double-colon rules. Fixes bug #4518, reported (with patch) by
1923 Andrew Chatham <chatham@google.com>.
1924
19252004-01-07 Paul D. Smith <psmith@gnu.org>
1926
1927 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1928 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1929 AC_FUNC_SETVBUF_REVERSED.
1930
1931 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1932 (MAKE Variable): Fix Savannah bug #4898.
1933
1934 * job.c (construct_command_argv_internal): Add "!" to the list of
1935 shell escape chars. POSIX sh allows it to appear before a
1936 command, to negate the exit code. Fixes bug #6404.
1937
1938 * implicit.c (pattern_search): When matching an implicit rule,
1939 remember which dependencies have the ignore_mtime flag set.
1940 Original fix provided in Savannah patch #2349, by Benoit
1941 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1942
19432003-11-22 Paul D. Smith <psmith@gnu.org>
1944
1945 * README.W32.template (Outputs): Clarification on -j with
1946 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1947 <jg-make@jguk.org>.
1948
19492003-11-02 Paul D. Smith <psmith@gnu.org>
1950
1951 * function.c (func_if): Strip all the trailing whitespace from the
1952 condition, then don't expand it. Fixed bug # 5798.
1953
1954 * expand.c (recursively_expand_for_file): If we're expanding a
1955 variable with no file context, then use the variable's context.
1956 Fixes bug # 6195.
1957
19582003-10-21 Paul D. Smith <psmith@gnu.org>
1959
1960 * main.c (log_working_directory): Add newlines to printf()s.
1961
1962 * README.cvs: Add a note to ignore warnings during autoreconf.
1963
1964 * maintMakefile (po_repo): Set a new URL for PO file updates.
1965 (get-config/config.guess get-config/config.sub): Get these files
1966 from the Savannah config project instead of ftp.gnu.org.
1967
19682003-10-05 Paul Eggert <eggert@twinsun.com>
1969
1970 * main.c (main): Avoid potential subscript error if environ has
1971 short strings.
1972
19732003-08-22 Paul D. Smith <psmith@gnu.org>
1974
1975 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1976 systems which don't yet implement the C89 standard :-/.
1977
19782003-07-18 Paul D. Smith <psmith@gnu.org>
1979
1980 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1981 [WINDOWS32]: Initialize hash.
1982
19832003-06-19 Earnie Boyd <earnie@uses.sf.net>
1984
1985 * dir.c (read_dirstream): Provide a workaround for broken versions of
1986 the MinGW dirent structure.
1987
19882003-05-30 Earnie Boyd <earnie@users.sf.net>
1989
1990 * w32/include/dirent.h: Add __MINGW32__ filter.
1991
19922003-05-30 Earnie Boyd <earnie@users.sf.net>
1993
1994 * make.h: Add global declaration of *make_host.
1995 * main.c (print_usage): Remove local declaration of *make_host.
1996 (print_version): Display "This program built for ..." after Copyright
1997 notice.
1998
19992003-05-30 Earnie Boyd <earnie@users.sf.net>
2000
2001 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2002 execution of "makeinfo --html make.texi".
2003
20042003-04-30 Paul D. Smith <psmith@gnu.org>
2005
2006 * build.template: Make some changes to maybe allow this script to
2007 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2008
2009 * README.OS2.template: New file for OS/2 support. Original
2010 contributed by Andreas Buening.
2011 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2012 DOS-style paths.
2013
20142003-04-19 Paul D. Smith <psmith@gnu.org>
2015
2016 Fix bug #1405: allow a target to match multiple pattern-specific
2017 variables.
2018
2019 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2020 variable.c, where they've always belonged.
2021 * rule.h: Move the prototypes and struct pattern_var as well.
2022 * variable.c (initialize_file_variables): Invoke
2023 lookup_pattern_var() in a loop, until no more matches are found.
2024 If a match is found, create a new variable set for the target's
2025 pattern variables. Then merge the contents of each matching
2026 pattern variable set into the target's pattern variable set.
2027 (lookup_pattern_var): Change this function to be usable
2028 in a loop. It takes a starting position: if NULL, start at the
2029 beginning; if non-NULL, start with the pattern variable after that
2030 position, and return the next matching pattern.
2031 (create_pattern_var): Create a unique instance of
2032 pattern-specific variables for every definition in the makefile.
2033 Don't combine the same pattern together. This allows us to
2034 process the variable handling properly even when the same pattern
2035 is used multiple times.
2036 (parse_variable_definition): New function: break out the parsing
2037 of a variable definition line from try_variable_definition.
2038 (try_variable_definition): Call parse_variable_definition to
2039 parse.
2040 (print_variable_data_base): Print out pattern-specific variables.
2041 * variable.h (struct variable): Remember when a variable is
2042 conditional. Also remember its flavor.
2043 (struct pattern_var): Instead of keeping a variable set, we just
2044 keep a single variable for each pattern.
2045 * read.c (record_target_var): Each pattern variable contains only a
2046 single variable, not a set, so create it properly.
2047 * doc/make.texi (Pattern-specific): Document the new behavior.
2048
20492003-04-17 Paul D. Smith <psmith@gnu.org>
2050
2051 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2052 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2053 file/directory naming rules for VMS so I can't tell whether this
2054 is correct or not.
2055
20562003-04-09 Paul D. Smith <psmith@gnu.org>
2057
2058 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2059 DOS-style pathnames: backslash separators and drive specifiers.
2060
20612003-03-28 Paul D. Smith <psmith@gnu.org>
2062
2063 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2064 the intermediate flag on all targets. Fixes bug #2515.
2065
20662003-03-24 Paul D. Smith <psmith@gnu.org>
2067
2068 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2069 Upgrade to autoconf 2.57 and automake 1.7.3.
2070
2071 * job.c: More OS/2 changes from Andreas Buening.
2072
2073 * file.c (print_file): Fix variable initialization.
2074 Fixes bug #2892.
2075
2076 * remake.c (notice_finished_file):
2077
2078 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2079 some calls (like readdir()) return NULL in valid situations
2080 without resetting errno. Fixes bug #2846.
2081
20822003-02-25 Paul D. Smith <psmith@gnu.org>
2083
2084 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2085
2086 * job.c (_is_unixy_shell) [OS/2]: New function.
2087 Set default shell to /bin/sh.
2088 (reap_children): Close the job_rfd pipe here since we don't use a
2089 SIGCHLD handler.
2090 (set_child_handler_action_flags): define this to empty on OS/2.
2091 (start_job_command): Close the jobserver pipe and use
2092 child_execute_job() instead of fork/exec.
2093 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2094 rather than exec'ing, then reconfigure stdin/stdout.
2095 (exec_command): Rewrite to use spawn instead of exec. Return the
2096 PID of the child.
2097
2098 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2099 in DOS. Handle the TEMP environment variable as in DOS. Don't
2100 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2101 use -j in DOS mode. Use child_execute_job() instead of
2102 exec_command().
2103
2104 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2105 spawn() instead.
2106
2107 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2108 prototypes that return values.
2109
2110 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2111
2112 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2113 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2114 for OS/2.
2115 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2116 DOS paths.
2117
21182003-02-24 Paul D. Smith <psmith@gnu.org>
2119
2120 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2121 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2122 (child_execute_job) [VMS]: Handle error status properly.
2123 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2124
2125 * function.c (func_shell): Use EINTRLOOP() while reading from the
2126 subshell pipe (Fixes bug #2502).
2127 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2128 jobserver pipe.
2129 * main.c (main): Ditto.
2130
21312003-01-30 Paul D. Smith <psmith@gnu.org>
2132
2133 * read.c (eval): eval() was not fully reentrant, because the
2134 collapsed buffer was static. Change it to be an automatic
2135 variable so that eval() can be invoked recursively.
2136 Fixes bug # 2238.
2137 (eval): Apply patch # 1022: fix memory reference error on long
2138 target-specific variable lines.
2139 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2140
2141 * function.c (check_numeric): Combine the is_numeric() function
2142 into this function, since it's only called from one place.
2143 Constify this function. Have it print the incorrect string in the
2144 error message. Fixes bug #2407.
2145 (strip_whitespace): Constify.
2146 (func_if): Constify.
2147 * expand.c (expand_argument): Constify.
2148
21492003-01-29 Paul D. Smith <psmith@gnu.org>
2150
2151 Fix bug # 2169, also reported by other people on various systems.
2152
2153 * make.h: Some systems, such as Solaris and PTX, do not fully
2154 implement POSIX-compliant SA_RESTART functionality; important
2155 system calls like stat() and readdir() can still fail with EINTR
2156 even if SA_RESTART has been set on the signal handler. So,
2157 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2158 EINTR for system calls which return -1 or 0 (NULL), respectively,
2159 on error.
2160 Also, remove the old atomic_stat()/atomic_readdir() and
2161 HAVE_BROKEN_RESTART handling.
2162
2163 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2164
2165 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2166 * remake.c (touch_file): Ditto.
2167
2168 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2169 * read.c (construct_include_path): Ditto.
2170 * remake.c (name_mtime): Ditto.
2171 * vpath.c (selective_vpath_search): Ditto.
2172 * dir.c (find_directory): Ditto.
2173 (local_stat): Ditto.
2174 (find_directory): Use ENULLLOOP() to wrap opendir().
2175 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2176
2177 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2178 atomic_readdir() handling.
2179
21802003-01-22 Paul D. Smith <psmith@gnu.org>
2181
2182 * function.c (func_call): Fix Bug #1744. If we're inside a
2183 recursive invocation of $(call ...), mask any of the outer
2184 invocation's arguments that aren't used by this one, so that this
2185 invocation doesn't "inherit" them accidentally.
2186
21872002-12-05 Paul D. Smith <psmith@gnu.org>
2188
2189 * function.c (subst_expand): Valery Khamenia reported a
2190 pathological performance hit when doing substitutions on very
2191 large values with lots of words: turns out we were invoking
2192 strlen() a ridiculous number of times. Instead of having each
2193 call to sindex() call strlen() again, keep track of how much of
2194 the text we've seen and pass the length to sindex().
2195
21962002-11-19 Paul D. Smith <psmith@gnu.org>
2197
2198 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2199
2200
22012002-11-16 Paul D. Smith <psmith@gnu.org>
2202
2203 * NMakefile.template (OBJS): Add hash.c object file.
2204 * SMakefile.template (srcs): Ditto.
2205 * Makefile.ami (objs): Ditto.
2206 * build_w32.bat: Ditto.
2207
2208 * Makefile.DOS.template: Remove extra dependencies.
2209
22102002-10-25 Paul D. Smith <psmith@gnu.org>
2211
2212 * expand.c (install_variable_buffer): New function. Install a new
2213 variable_buffer context and return the previous one.
2214 (restore_variable_buffer): New function. Free the current
2215 variable_buffer context and put a previously saved one back.
2216 * variable.h: Prototypes for {install,restore}_variable_buffer.
2217 * function.c (func_eval): Push a new variable_buffer context
2218 before we eval, then restore the old one when we're done.
2219 Fixes Bug #1517.
2220
2221 * read.c (install_conditionals): New function. Install a new
2222 conditional context and return the previous one.
2223 (restore_conditionals): New function. Free the current
2224 conditional context and put a previously saved one back.
2225 (eval): Use the {install,restore}_conditionals for "include"
2226 handling.
2227 (eval_buffer): Use {install,restore}_conditionals to preserve the
2228 present conditional state before we evaluate the buffer.
2229 Fixes Bug #1516.
2230
2231 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2232 and $(value ...).
2233 (Recursion): Add a variable index entry for CURDIR.
2234
2235 * README.cvs: Update to appropriate versions.
2236 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2237 don't need to copy loadavg.c: automake is smart enough to create
2238 it for me. Still have a bug in automake related to ansi2knr tho.
2239
22402002-10-14 Paul D. Smith <psmith@gnu.org>
2241
2242 * remake.c (notice_finished_file): Only touch targets if they have
2243 at least one command (as per POSIX). Resolve Bug #1418.
2244
2245 * *.c: Convert to using ANSI C-style function definitions.
2246 * Makefile.am: Enable the ansi2knr feature of automake.
2247 * configure.in: ditto.
2248
22492002-10-13 Paul D. Smith <psmith@gnu.org>
2250
2251 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2252 for automatic variable values like $^, etc. In the case of very
2253 large lists of prerequisites this causes problems. Instead reuse
2254 a static buffer (resizeable) for each variable.
2255
2256 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2257 target-specific variable definitions. Check for it and set an
2258 "exported" flag.
2259 (record_target_var): Set the export field to v_export if the
2260 "exported" flag is set.
2261 * doc/make.texi (Target-specific): Document the ability to use
2262 "export".
2263
2264 * doc/make.texi: Change the name of the section on automatic
2265 variables from "Automatic" to "Automatic Variables". Added text
2266 clarifying the scope of automatic variables.
2267
22682002-10-04 Paul D. Smith <psmith@gnu.org>
2269
2270 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2271 as () braces.
2272 (record_files): Ditto.
2273
2274 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2275 the search for the '=' to only within the enclosing parens.
2276
22772002-10-03 Paul D. Smith <psmith@gnu.org>
2278
2279 Version 3.80 released.
2280
2281 * dir.c: Change hash functions to use K&R function definition style.
2282 * function.c: Ditto.
2283 * read.c: Ditto.
2284 * variable.c: Ditto.
2285
2286 Update to automake 1.7.
2287
2288 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2289 (pdf): Remove this target as automake now provides one.
2290
2291 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2292
22932002-09-30 Martin P.J. Zinser <zinser@decus.de>
2294
2295 * makefile.com: Updates for GNU make 3.80.
2296 * makefile.vms: Ditto.
2297
22982002-09-23 Paul D. Smith <psmith@gnu.org>
2299
2300 * read.c (enum make_word_type): Remove w_comment.
2301 (get_next_mword): Don't treat comment characters as special; where
2302 this function is used we will never see a comment (it's stripped
2303 before we get here) and treating comments specially means that
2304 targets like "foo\#bar" aren't handled properly.
2305
23062002-09-18 Paul D. Smith <psmith@gnu.org>
2307
2308 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2309
2310 * read.c (eval): Expansion of arguments to export/unexport was
2311 ignoring all arguments after the first one. Change the algorithm
2312 to expand the whole line once, then parse the results.
2313
23142002-09-17 Paul D. Smith <psmith@gnu.org>
2315
2316 Fix Bug #940 (plus another bug I found while looking at this):
2317
2318 * read.c (record_target_var): enter_file() will add a new entry if
2319 it's a double-colon target: we don't want to do that in this
2320 situation. Invoke lookup_file() and only enter_file() if it does
2321 not already exist. If the file we get back is a double-colon then
2322 add this variable to the "root" double-colon target.
2323
2324 * variable.c (initialize_file_variables): If this file is a
2325 double-colon target but is not the "root" target, then initialize
2326 the root and make the root's variable list the parent of our
2327 variable list.
2328
23292002-09-13 Paul D. Smith <psmith@gnu.org>
2330
2331 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2332
2333 * hash.c (round_up_2): Get rid of a warning.
2334
23352002-09-12 Paul D. Smith <psmith@gnu.org>
2336
2337 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2338 so it doesn't complain about getloadavg.c.
2339
2340 * commands.c (set_file_variables): Make sure we always alloca() at
2341 least 1 character for the value of $? (for '\0').
2342
23432002-09-11 Paul D. Smith <psmith@gnu.org>
2344
2345 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2346 macro to use RESULT instead of the incorrect _RESULT_.
2347
2348 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2349 and atomic_readdir(). We need to #include dirent.h to get this to
2350 work.
2351 * misc.c (atomic_readdir): Fix typos.
2352
23532002-09-10 Paul D. Smith <psmith@gnu.org>
2354
2355 * read.c (eval): Expand variable lists given to export and
2356 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2357 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2358
2359 * doc/make.texi (Variables/Recursion): Document this.
2360 (Conditional Syntax): And here.
2361
23622002-09-09 Paul D. Smith <psmith@gnu.org>
2363
2364 * configure.in: Check for memmove().
2365
23662002-09-07 Paul D. Smith <psmith@gnu.org>
2367
2368 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2369 Michael Sterrett <msterret@coat.com> reports that while it has
2370 SA_RESTART, it does not work properly.
2371
2372 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2373 that invokes stat() and loops to do it again if it returns EINTR.
2374 (atomic_readdir): Ditto, with readdir().
2375
2376 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2377 and readdir() to atomic_stat() and atomic_readdir().
2378
23792002-09-04 Paul D. Smith <psmith@gnu.org>
2380
2381 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2382 reports that GNU make sometimes doesn't recognize that targets can
2383 be made, when directories can be created as prerequisites. He
2384 reports that changing the order of predicates in the DEP->changed
2385 flag test so that lookup_file() is always performed, solves this
2386 problem.
2387
23882002-08-08 Paul D. Smith <psmith@gnu.org>
2389
2390 * configure.in: Require a newer version of gettext.
2391
2392 * misc.c (perror_with_name): Translate the format string (for
2393 right-to-left language support).
2394 (pfatal_with_name): Ditto.
2395
2396 * main.c: Create a static array of strings to store the usage
2397 text. This is done to facilitate translations.
2398 (struct command_switch): Remove argdesc and description fields.
2399 (switches): Remove values for obsolete fields.
2400 (print_usage): Print each element of the usage array.
2401
2402 * hash.c: Change function definitions to be K&R style.
2403
24042002-08-02 Paul D. Smith <psmith@gnu.org>
2405
2406 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2407 this one because it's too hard to get right. We'll look at it for
2408 a future release.
2409 * main.c (main): Don't create the .TARGETS variable.
2410 * variable.c (handle_special_var): Don't handle .TARGETS.
2411
24122002-08-01 Paul D. Smith <psmith@gnu.org>
2413
2414 * main.c (switches): Add a new option, -B (--always-make). If
2415 specified, make will rebuild all targets that it encounters even
2416 if they don't appear to be out of date.
2417 (always_make_flag): New flag.
2418 * make.h: Extern always_make_flag.
2419 * remake.c (update_file_1): Check always_make_flag; if it's set we
2420 will always rebuild any target we can, even if none of its
2421 prerequisites are newer.
2422 * NEWS: Mention it.
2423
2424 * doc/make.texi (Shell Function): Make it clear that make
2425 variables marked as "export" are not passed to instances of the
2426 shell function.
2427
2428 Add new introspection variable .VARIABLES and .TARGETS.
2429
2430 * variable.c (handle_special_var): New function. If the variable
2431 reference passed in is "special" (.VARIABLES or .TARGETS),
2432 calculate the new value if necessary. .VARIABLES is handled here:
2433 walk through the hash of defined variables and construct a value
2434 which is a list of the names. .TARGETS is handled by
2435 build_target_list().
2436 (lookup_variable): Invoke handle_special_var().
2437 * file.c (build_target_list): Walk through the hask of known files
2438 and construct a list of the names of all the ones marked as
2439 targets.
2440 * main.c (main): Initialize them to empty (and as simple variables).
2441 * doc/make.texi (Special Variables): Document them.
2442 * NEWS: Mention them.
2443
2444 * variable.h (struct variable): Add a new flag "exportable" which
2445 is true if the variable name is valid for export.
2446 * variable.c (define_variable_in_set): Set "exportable" when a new
2447 variable is defined.
2448 (target_environment): Use the "exportable" flag instead of
2449 re-checking the name here... an efficiency improvement.
2450
24512002-07-31 Paul D. Smith <psmith@gnu.org>
2452
2453 * config.h-vms.template: Updates to build on VMS. Thanks to
2454 Brian_Benning@aksteel.com for helping verify the build.
2455 * makefile.com: Build the new hash.c file.
2456 * hash.h: Use strcpmi(), not stricmp(), in the
2457 HAVE_CASE_INSENSITIVE_FS case.
2458
24592002-07-30 Paul D. Smith <psmith@gnu.org>
2460
2461 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2462 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2463 Reported by <Brian_Benning@aksteel.com>.
2464
24652002-07-10 Paul D. Smith <psmith@gnu.org>
2466
2467 * variable.c (pop_variable_scope): Remove variable made unused by
2468 new hash infrastructure.
2469 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2470 comparisons as well as name comparisons.
2471 * variable.h: Add a prototype for new hash_init_function_table().
2472 * file.c (lookup_file): Remove variables made unused by new hash
2473 infrastructure.
2474 * dir.c (directory_contents_hash_2): Missing return of hash value.
2475 (dir_contents_file_exists_p): Remove variables made unused by new
2476 hash infrastructure.
2477
2478
2479 Installed Greg McGary's integration of the hash functions from the
2480 GNU id-utils package:
2481
24822002-07-10 Greg McGary <greg@mcgary.org>
2483
2484 * scripts/functions/filter-out: Add literals to to the
2485 pattern space in order to add complexity, and trigger
2486 use of an internal hash table. Fix documentation strings.
2487 * scripts/targets/INTERMEDIATE: Reverse order of files
2488 passed to expected `rm' command.
2489
24902002-07-10 Greg McGary <greg@mcgary.org>
2491
2492 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

2534 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
2535 (files): Change type to `struct hash_table'.
2536 (lookup_file): Use new hash table package.
2537 (enter_file): Likewise.
2538 (remove_intermediates): Likewise.
2539 (snap_deps): Likewise.
2540 (print_file_data_base): Likewise.
2541
2542 * function.c
2543 (function_table_entry_hash_1, function_table_entry_hash_2,
2544 function_table_entry_hash_cmp): New functions.
2545 (lookup_function): Remove `table' argument.
2546 Use new hash table package.

2549 (struct a_pattern): New struct.
2550 (func_filter_filterout): Pass through patterns noting boundaries
2551 and '%', if present. Note a_word length. Use a hash table if
2552 arglists are large enough to justify cost.
2553 (function_table_init): Renamed from function_table.
2554 (function_table): Declare as `struct hash_table'.
2555 (FUNCTION_TABLE_ENTRIES): New constant.
2556 (hash_init_function_table): New function.

2561 (uniquize_deps): Use hash table to efficiently identify duplicates.
2562 (find_char_unquote): Accept two char-constant stop chars, rather
2563 than a string constant, avoiding zillions of calls to strchr.
2564 Tighten inner search loops to test only for desired delimiters.
2565
2566 * variable.c (variable_hash_1, variable_hash_2,
2567 variable_hash_cmp): New functions.

25822002-07-10 Paul D. Smith <psmith@gnu.org>
2583
2584 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2585 prerequisite list. A real SysV make will expand the entire
2586 prerequisites list _twice_: we don't do that as it's a big
2587 backward-compatibility problem. We only replace those specific
2588 variables.
2589
2590 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2591 references left in the list of prerequisites. Check for .POSIX as
2592 we record targets, so we can disable non-POSIX behavior while
2593 reading makefiles as well as running them.
2594 (eval): Check the prerequisite list to see if we have anything
2595 that looks like a SysV prerequisite variable reference.
2596
25972002-07-09 Paul D. Smith <psmith@gnu.org>
2598
2599 * doc/make.texi (Prerequisite Types): Add a new section describing
2600 order-only prerequisites.
2601
2602 * read.c (uniquize_deps): If we have the same file as both a
2603 normal and order-only prereq, get rid of the order-only prereq,
2604 since the normal one supersedes it.
2605
26062002-07-08 Paul D. Smith <psmith@gnu.org>
2607
2608 * AUTHORS: Added Greg McGary to the AUTHORS file.
2609 * NEWS: Blurbed order-only prerequisites.
2610 * file.c (print_file): Show order-only deps properly when printing
2611 the database.
2612
2613 * maintMakefile: Add "update" targets for wget'ing the latest
2614 versions of various external files. Taken from Makefile.maint in
2615 autoconf, etc.
2616
2617 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2618 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2619
26202002-07-07 Paul D. Smith <psmith@gnu.org>
2621
2622 * po/*.po: Remove. We'll use wget to retrieve them at release
2623 time.
2624
2625 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2626 rather than a shell you get an exception. Make sure we look up
2627 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2628
2629 * remake.c (notice_finished_file): Fix handling of -t flag.
2630 Patch provided by Henning Makholm <henning@makholm.net>.
2631
2632 * implicit.c (pattern_search): Some systems apparently run short
2633 of stack space, and using alloca() in this function caused an
2634 overrun. I modified it to use xmalloc() on the two variables
2635 which seemed like they might get large. Fixes Bug #476.
2636
2637 * main.c (print_version): Update copyright notice to conform with
2638 GNU standards.
2639 (print_usage): Update help output.
2640
2641 * function.c (func_eval): Create a new make function, $(eval
2642 ...). Expand the arguments, put them into a buffer, then invoke
2643 eval_buffer() on the resulting string.
2644 (func_quote): Create a new function, $(quote VARNAME). Inserts
2645 the value of the variable VARNAME without expanding it any
2646 further.
2647
2648 * read.c (struct ebuffer): Change the linebuffer structure to an
2649 "eval buffer", which can be either a file or a buffer.
2650 (eval_makefile): Move the code in the old read_makefile() which
2651 located a makefile into here: create a struct ebuffer with that
2652 information. Have it invoke the new function eval() with that
2653 ebuffer.
2654 (eval_buffer): Create a new function that creates a struct ebuffer
2655 that holds a string buffer instead of a file. Have it invoke
2656 eval() with that ebuffer.
2657 (eval): New function that contains the guts of the old
2658 read_makefile() function: this function parses makefiles. Obtains
2659 data to parse from the provided ebuffer. Some modifications to
2660 make the flow of the function cleaner and clearer. Still could
2661 use some work here...
2662 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2663 contents of the define/endef variable from the ebuffer.
2664 (readstring): Read the next line from a string-style ebuffer.
2665 (readline): Read the next line from an ebuffer. If it's a string
2666 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2667 from the file.
2668
2669 * dep.h (eval_buffer): Prototype eval_buffer();
2670
2671 * variable.c (do_variable_definition): Make sure that all
2672 non-target-specific variables are registered in the global set.
2673 If we're invoked from an $(eval ...) we might be inside a $(call
2674 ...) or other function which has pushed a variable scope; we still
2675 want to define our variables from evaluated makefile code in the
2676 global scope.
2677
26782002-07-03 Greg McGary <greg@mcgary.org>
2679
2680 * dep.h (struct dep) [ignore_mtime]: New member.
2681 [changed]: convert to a bitfield.
2682 * implicit.c (pattern_search): Zero ignore_mtime.
2683 * main.c (main, handle_non_switch_argument): Likewise.
2684 * rule.c (convert_suffix_rule): Likewise.
2685 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2686 (read_makefile): Parse '|' in prerequisite list.
2687 (uniquize_deps): Consider ignore_mtime when comparing deps.
2688 * remake.c (update_file_1, check_dep): Don't force remake for
2689 dependencies that have d->ignore_mtime.
2690 * commands.c (FILE_LIST_SEPARATOR): New constant.
2691 (set_file_variables): Don't include a
2692 prerequisite in $+, $^ or $? if d->ignore_mtime.
2693 Define $|.
2694
26952002-06-18 Paul D. Smith <psmith@gnu.org>
2696
2697 * make.texinfo: Updates for next revision. New date/rev/etc.
2698 Recreate all Info menus. Change license on the manual to the GNU
2699 Free Documentation License. A number of typos.
2700 (Variables Simplify): Don't use "-" before it's defined.
2701 (Automatic Prerequisites): Rewrite the target example to work
2702 properly if the compile fails. Remove incorrect comments about
2703 how "set -e" behaves.
2704 (Text Functions): Move the "word", "wordlist", "words", and
2705 "firstword" functions here, from "File Name Functions".
2706 * make-stds.texi: Update from latest GNU version.
2707 * fdl.texi: (created) Import the latest GNU version.
2708
27092002-06-06 Paul D. Smith <psmith@gnu.org>
2710
2711 * variable.c (do_variable_definition): New function: extract the
2712 part of try_variable_definition() that actually sets the value
2713 into a separate function.
2714 (try_variable_definition): Call do_variable_definition() after
2715 parsing the variable definition string.
2716 (define_variable_in_set): Make the name argument const.
2717
2718 * variable.h (enum variable_flavor): Make public.
2719 (do_variable_definition): Create prototype.
2720
2721 * read.c (read_all_makefiles): Create a new built-in variable,
2722 MAKEFILE_LIST.
2723 (read_makefile): Add each makefile read in to this variable value.
2724
27252002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2726
2727 * Makefile.DOS.template: Tweak according to changes in the
2728 distribution. Add back the dependencies of *.o files.
2729
2730 * configh.dos.template: Synchronize with config.h.in.
2731
27322002-05-09 Paul D. Smith <psmith@gnu.org>
2733
2734 * file.c (file_timestamp_now): Use K&R function declaration.
2735
2736 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2737 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2738 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2739 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2740 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2741 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2742 nlist.n_name is a pointer rather than an array.
2743
2744 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2745 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2746 * configure.in: Use it instead of the old version.
2747
2748 * main.c (main): Prefer setvbuf() to setlinebuf().
2749
27502002-05-08 Paul D. Smith <psmith@gnu.org>
2751
2752 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2753 (loadavg_LDADD): Ditto.
2754
27552002-04-29 Paul D. Smith <psmith@gnu.org>
2756
2757 * expand.c (recursively_expand_for_file): Rename
2758 recursively_expand() to recursively_expand_for_file() and provide
2759 an extra argument, struct file. If the argument is provided, set
2760 the variable scope to that of the file before expanding.
2761 * variable.h (recursively_expand): Make this a macro that invokes
2762 recursively_expand_for_file() with a NULL file pointer.
2763 * variable.c (target_environment): Call the renamed function and
2764 provide the current file context.
2765 Fixes Debian bug #144306.
2766
27672002-04-28 Paul D. Smith <psmith@gnu.org>
2768
2769 Allow $(call ...) user-defined variables to be self-referencing
2770 without throwing an error. Allows implementation of transitive
2771 closures, among other possibly useful things.
2772 Requested by: Philip Guenther <guenther@sendmail.com>
2773
2774 * variable.h (struct variable): Add a new field: exp_count, and
2775 new macros to hold its size and maximum value.
2776 (warn_undefined): Make this a macro.
2777 * variable.c (define_variable_in_set): Initialize it.
2778 * expand.c (recursively_expand): If we detect recursive expansion
2779 of a variable, check the exp_count field. If it's greater than 0
2780 allow the recursion and decrement the count.
2781 (warn_undefined): Remove this (now a macro in variable.h).
2782 * function.c (func_call): Before we expand the user-defined
2783 function, modify its exp_count field to contain the maximum
2784 number of recursive calls we'll allow. After the call, reset it
2785 to 0.
2786
27872002-04-21 Paul D. Smith <psmith@gnu.org>
2788
2789 Modified to use latest autoconf (2.53), automake (1.6.1), and
2790 gettext (0.11.1). We're using gettext's new "external" support,
2791 to avoid including libintl source with GNU make.
2792
2793 * README.cvs: New file. Explain how to build GNU make from CVS.
2794
2795 * configure.in: Modify checking for the system glob library.
2796 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2797 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2798 etc. will manage it correctly). Set an automake conditional
2799 USE_LOCAL_GLOB to decide whether to compile the glob library.
2800
2801 * getloadavg.c (main): Include make.h in the "TEST" program to
2802 avoid warnings.
2803
2804 * Makefile.am: Remove special rules for loadavg. Replace them
2805 with Automake capabilities for building extra programs.
2806
2807 * signame.c: This file does nothing if the system provide
2808 strsignal(). If not, it implements strsignal(). If the system
2809 doesn't define sys_siglist, then we make our own; otherwise we use
2810 the system version.
2811 * signame.h: Removed.
2812
2813 * main.c (main): No need to invoke signame_init(). Update copyright.
2814
2815 * ABOUT-NLS: Removed.
2816 * gettext.c: Removed.
2817 * gettext.h: Get a simplified copy from the gettext package.
2818 * po/*: Created.
2819 * i18n/*.po: Moved to po/.
2820 * i18n/: Removed.
2821
2822 * config/*: Created. Contains package configuration helper files.
2823 * config.guess, config.sub: Moved to config directory.
2824
2825 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2826 Rework to use new-style autoconf features. Use the "external"
2827 mode for gettext. Make the build.sh config file conditional on
2828 whether build.sh.in exists, to avoid autoconf errors.
2829 * acinclude.m4: Removed almost all macros as being obsolete.
2830 Rewrote remaining macros to use AC_DEFINE.
2831 * acconfig.h: Removed.
2832
2833 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2834 conditional to handle customs support. Remove special handling
2835 for i18n features.
2836
28372002-04-20 Paul D. Smith <psmith@gnu.org>
2838
2839 * function.c (func_call): Don't mark the argument variables $1,
2840 etc. as recursive. They've already been fully expanded so
2841 there's no need to do it again, and doing so strips escaped $'s.
2842 Reported by Sebastian Glita <glseba@yahoo.com>.
2843
2844 * remake.c (notice_finished_file): Walk through double-colon
2845 entries via the prev field, not the next field!
2846 Reported by Greg McGary <greg@mcgary.org>.
2847
2848 * main.c (main): If the user specifies -q and asks for a specific
2849 target which is a makefile, we got an assert. In that case it
2850 turns out we should continue normally instead.
2851
2852 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2853
2854 * i18n/he.po: Installed a new translation.
2855
28562002-01-07 Paul D. Smith <psmith@gnu.org>
2857
2858 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2859
28602001-12-04 Paul D. Smith <psmith@gnu.org>
2861
2862 * i18n/ja.po: Installed an updated translation.
2863
28642001-09-06 Paul Eggert <eggert@twinsun.com>
2865
2866 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2867 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2868
2869 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2870 are available.
2871 (main): Get rid of any avoidable limit on stack size.
2872
28732001-09-04 Paul D. Smith <psmith@gnu.org>
2874
2875 * i18n/da.po: Installed an updated translation.
2876
28772001-08-03 Paul D. Smith <psmith@gnu.org>
2878
2879 * i18n/fr.po: Installed an updated translation.
2880 Resolves Debian bug #106720.
2881
28822001-06-13 Paul D. Smith <psmith@gnu.org>
2883
2884 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2885 translation.
2886
28872001-06-11 Paul D. Smith <psmith@gnu.org>
2888
2889 * i18n/ko.po: Installed a new translation.
2890
28912001-05-06 Paul D. Smith <psmith@gnu.org>
2892
2893 Modify the EINTR handling.
2894
2895 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2896 the way in which we manage the file descriptor/signal handler race
2897 trap to be more efficient.
2898
28992001-05-06 Paul Eggert <eggert@twinsun.com>
2900
2901 Restart almost all system calls that are interrupted, instead
2902 of worrying about EINTR. The lone exception is the read() for
2903 job tokens.
2904
2905 * configure.in (HAVE_SA_RESTART): New macro.
2906 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2907 * main.c (main): Use SA_RESTART instead of the old,
2908 nonstandard SA_INTERRUPT.
2909
2910 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2911 * main.c (bsd_signal): New function or macro,
2912 if the implementation doesn't supply it.
2913 (The bsd_signal function will be in POSIX 1003.1-200x.)
2914 (HANDLESIG): Remove.
2915 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2916
2917 * make.h (EINTR_SET): Remove.
2918 (SA_RESTART): New macro.
2919
2920 * arscan.c (ar_member_touch): Don't worry about EINTR.
2921 * function.c (func_shell): Likewise.
2922 * job.c (reap_children, free_child, new_job): Likewise.
2923 * main.c (main): Likewise.
2924 * remake.c (touch_file, name_mtime): Likewise.
2925
2926 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2927 if fstat failed with errno!=EINTR, the error was ignored.
2928
2929 * job.c (set_child_handler_action_flags): New function.
2930 (new_job): Use it to temporarily clear the SIGCHLD action flags
2931 while reading the token.
2932
29332001-05-02 Paul D. Smith <psmith@gnu.org>
2934
2935 * job.c (start_job_command): Don't add define/endef per-line flags
2936 to the top-level flags setting.
2937
29382001-04-03 Paul D. Smith <psmith@gnu.org>
2939
2940 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2941 bit on error, so check for odd return values, not non-0 return
2942 values.
2943 (VMS_get_member_info): Calculate the timezone differences correctly.
2944 Reported by John Fowler <jfowler@nyx.net>.
2945
2946
29472001-03-14 Paul D. Smith <psmith@gnu.org>
2948
2949 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2950 value before invoking define_variable().
2951 Reported by John Fowler <jfowler@nyx.net>.
2952
29532001-02-07 Paul D. Smith <psmith@gnu.org>
2954
2955 * read.c (record_target_var): If we reset the variable due to a
2956 command-line variable setting overriding it, turn off the "append"
2957 flag.
2958
29592001-01-17 Paul D. Smith <psmith@gnu.org>
2960
2961 * variable.c (lookup_variable) [VMS]: When getting values from the
2962 environment, allocate enough space for the _value_ plus escapes,
2963 not enough space for the name plus escapes :-/.
2964 Reported by John Fowler <jfowler@nyx.net>.
2965
2966 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2967 warnings that make generates, so it doesn't look like an error.
2968 Reported by Karl Berry <karl@gnu.org>.
2969
2970
2971 Fix for PR/2020: Rework appended target-specific variables. I'm
2972 fairly confident this algorithm is finally correct.
2973
2974 * expand.c (allocated_variable_append): Rewrite. Instead of
2975 expanding each appended variable then adding all the expanded
2976 strings together, we append all the unexpanded values going up
2977 through the variable set contexts, then expand the final result.
2978 This behaves just like non-target-specific appended variable
2979 values, while the old way didn't in various corner cases.
2980 (variable_append): New function: recursively append the unexpanded
2981 value of a variable, walking from the outermost variable scope to
2982 the innermost.
2983 * variable.c (lookup_variable): Remove the code that looked up the
2984 variable set list if the found variable was "append". We don't
2985 need this anymore.
2986 (lookup_variable_in_set): Make this non-static so we can use it
2987 elsewhere.
2988 (try_variable_definition): Use lookup_variable_in_set() rather
2989 than faking out current_variable_set_list by hand (cleanup).
2990 * variable.h: Add a prototype for the now non-static
2991 lookup_variable_in_set().
2992
29932000-11-17 Paul D. Smith <psmith@gnu.org>
2994
2995 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2996 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2997 before throwing a fit.
2998
29992000-11-17 Paul D. Smith <psmith@gnu.org>
3000
3001 * read.c (readline): CRLF calculations had a hole, if you hit the
3002 buffer grow scenario just right. Reworked the algorithm to avoid
3003 the need for len or lastlen at all. Problem description with
3004 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3005
30062000-10-24 Paul D. Smith <psmith@gnu.org>
3007
3008 * gettext.c (SWAP): Declare this with the prototype, otherwise
3009 some systems don't work (non-32-bit? Reported for Cray T3E).
3010 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3011
30122000-10-05 Paul D. Smith <psmith@gnu.org>
3013
3014 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3015 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3016
3017 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3018
30192000-09-22 Paul D. Smith <psmith@gnu.org>
3020
3021 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3022 parts of the real gettext.h here, and we expect to really include
3023 the real gettext.h later. If we keep this #define, it's ignored.
3024
30252000-09-21 Paul D. Smith <psmith@gnu.org>
3026
3027 * main.c (log_working_directory): Rework the text to use complete
3028 sentences, to make life simpler for the translators.
3029
30302000-08-29 Paul D. Smith <psmith@gnu.org>
3031
3032 * file.c (remove_intermediates): Print a debug message before we
3033 remove intermediate files, so the user (if she uses -d) knows
3034 what's going on.
3035
30362000-08-21 Paul D. Smith <psmith@gnu.org>
3037
3038 * variable.c (try_variable_definition): Change how we handle
3039 target-specific append variable defns: instead of just setting the
3040 value, expand it as an append _but_ only within the current
3041 target's context. Otherwise we lose all but the last value if the
3042 variable is appended more than once within the current target
3043 context. Fixes PR/1831.
3044
30452000-08-16 Paul D. Smith <psmith@gnu.org>
3046
3047 * function.c (func_shell): Nul-terminate the buffer before
3048 printing an exec error message (just in case it's not!).
3049 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3050
30512000-07-25 Paul D. Smith <psmith@gnu.org>
3052
3053 * job.c (construct_command_argv_internal): Add "~" to the list of
3054 sh_chars[] which disallow optimizing out the shell call.
3055
30562000-07-23 Paul Eggert <eggert@twinsun.com>
3057
3058 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3059 supersedes --disable-nsec-timestamps.
3060 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3061 * README: Remove --disable-nsec-timestamps.
3062
3063 * filedef.h (struct file.low_resolution_time): New member.
3064 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3065 * remake.c (update_file_1):
3066 Avoid spurious rebuilds due to low resolution time stamps,
3067 generalizing the earlier code that applied only to archive members.
3068 (f_mtime): Archive members always have low resolution time stamps.
3069
3070 * configure.in: Remove --disable-nsec-timestamps, as this has
3071 been superseded by .LOW_RESOLUTION_TIME.
3072
30732000-07-23 Paul Eggert <eggert@twinsun.com>
3074
3075 * configure.in (enable_nsec_timestamps): Renamed from
3076 make_cv_nsec_timestamps, since enable/disable options
3077 shouldn't be cached.
3078
30792000-07-23 Bruno Haible <haible@clisp.cons.org>
3080 and Paul Eggert <eggert@twinsun.com>
3081
3082 * file.c (file_timestamp_now):
3083 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3084 so that clock_gettime is not linked unless needed.
3085
3086 * filedef.h (FILE_TIMESTAMP_HI_RES):
3087 Remove definition; "configure" now does this.
3088
3089 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3090 to before high resolution file timestamp check,
3091 since that check now uses uintmax_t.
3092 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3093 high resolution file timestamps.
3094 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3095 so that we don't link in clock_gettime unnecessarily.
3096
30972000-07-17 Paul D. Smith <psmith@gnu.org>
3098
3099 * i18n/ja.po: New version of the translation file.
3100
31012000-07-07 Paul D. Smith <psmith@gnu.org>
3102
3103 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3104 the offset calculation.
3105 (name_mtime): Replace EINTR test with EINTR_SET macro.
3106
31072000-07-07 Paul Eggert <eggert@twinsun.com>
3108
3109 Fix for PR/1811:
3110
3111 * remake.c (update_file_1):
3112 Avoid spurious rebuilds of archive members due to their
3113 timestamp resolution being only one second.
3114 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3115 the clock's resolution being lower than file timestamps'.
3116 When warning about future timestamps, report only the discrepancy,
3117 not the absolute value of the timestamp and the current time.
3118
3119 * file.c (file_timestamp_now): New arg RESOLUTION.
3120 * filedef.h (file_timestamp_now): Likewise.
3121 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3122
31232000-07-05 Paul D. Smith <psmith@gnu.org>
3124
3125 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3126 to listp. Fixes PR/1793.
3127
31282000-06-26 Paul Eggert <eggert@twinsun.com>
3129
3130 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3131
3132 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3133
3134 * remake.c (f_mtime): Remove unused var memtime.
3135
31362000-06-25 Martin Buchholz <martin@xemacs.org>
3137
3138 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3139 Ran spell-check on make.texinfo.
3140
31412000-06-23 Paul D. Smith <psmith@gnu.org>
3142
3143 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3144 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3145 * make.h: Define these macros.
3146
3147 * Version 3.79.1 released.
3148
3149 * configure.in: Add a new option, --disable-nsec-timestamps, to
3150 avoid using sub-second timestamps on systems that support it. It
3151 can lead to problems, e.g. if your makefile relies on "cp -p".
3152 * README.template: Document the issue with "cp -p".
3153
3154 * config.guess, config.sub: Updated.
3155
