1 2009-06-09 Paul Smith <psmith@gnu.org>
3 * main.c (clean_jobserver): Clear the jobserver_fds options and
4 set job_slots to the default when we clean up.
5 (define_makeflags): Return the new MAKEFLAGS value.
6 (main): Reset MAKEFLAGS in the environment when we re-exec.
7 Fixes Savannah bug #18124.
9 2009-06-08 Paul Smith <psmith@gnu.org>
11 * read.c (eval): Collapse continuations post-semicolon on target-
12 specific variables. Fixes Savannah bug #17521.
14 2009-06-07 Paul Smith <psmith@gnu.org>
16 * job.c (reap_children): For older systems without waitpid() (are
17 there any of these left?) run wait(2) inside EINTRLOOP to handle
18 EINTR errors. Fixes Savannah bug #16401.
20 * (various): Debug message cleanup. Fixes Savannah bug #16469.
22 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
24 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
25 not the end, to catch second expansion $(eval ...) defining new
26 target/prereq relationships during snap_deps.
27 Fixes Savannah bug #24622.
29 * read.c (record_files): The second-expansion "f->updating" hack
30 was not completely correct: if assumed that the target with
31 commands always had prerequisites; if one didn't then the ordering
32 was messed up. Fixed for now to use f->updating to decide whether
33 to preserve the last element in the deps list... but this whole
34 area of constructing and reversing the deps list is too confusing
35 and needs to be reworked. Fixes Savannah bug #21198.
37 2009-06-06 Paul Smith <psmith@gnu.org>
39 * hash.c (hash_insert): Remove useless test for NULL.
40 Fixes Savannah bug #21823.
42 * make.h: Move SET_STACK_SIZE determination to make.h.
43 * main.c (main): New global variable, STACK_LIMIT, holds the
44 original stack limit when make was started.
45 * job.c (start_job_command): Reset the stack limit, if we changed it.
46 Fixes Savannah bug #22010.
48 * remake.c (check_dep): Only set the target's state to not-started
49 if it's not already running. Found this while testing -j10 builds
50 of glibc: various targets were being rebuilt multiple times.
51 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
54 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
55 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
58 2009-06-04 Paul Smith <psmith@gnu.org>
60 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
62 * maintMakefile: Modify access of config and gnulib Savannah
63 modules to use GIT instead of CVS.
65 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
66 Fixes Savannah bug #24655.
68 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
69 this can happen during some invocations of $(eval ...) for example.
70 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
72 2009-06-02 Paul Smith <psmith@gnu.org>
74 * configure.in: Check for fileno()
75 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
76 for the makefile file so invocations of $(shell ...) don't inherit it.
77 Fixes Savannah bug #24277.
79 2009-06-01 Paul Smith <psmith@gnu.org>
81 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
82 expansion was handled incorrectly. Rework the default goal
83 handling to save the variable only. Remove default_goal_file and
85 * read.c (eval): Check default_goal_var, not default_goal_name.
86 * read.c (record_target_var): Don't check default_goal_file here.
88 2009-05-31 Paul Smith <psmith@gnu.org>
90 * main.c (main): Expand the .DEFAULT_GOAL variable before using
91 it, and if the multi_glob() returns nothing (say it expanded to
92 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
94 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
95 $(and ..) to the reference. Fixes Savannah bug #25694.
97 * make.1: Be clear that some recipes will be executed even with -n.
98 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
100 * doc/make.texi (Override Directive): Make more clear how
101 overrides and appends interact.
102 Elucidates part of Savannah bug #26207.
104 * read.c (record_target_var): Don't reset the origin on
105 target-specific variables; try_variable_definition() will handle
106 this correctly. Fixes Savannah bug #26207.
108 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
109 Fixes Savannah bug #25712.
111 * implicit.c (pattern_search): Keep a pointer to the beginning of
112 the filename and save that instead of the constructed pointer.
113 Fixes Savannah bug #26593.
114 Patch by Mark Seaborn <mrs@mythic-beasts.com>
116 2009-05-30 Paul Smith <psmith@gnu.org>
118 * doc/make.texi (Multi-Line): Add a description of the new abilities
119 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
120 "command sequence" vs. "recipe" syntax.
121 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
122 after a define, to create variables with those flavors.
124 2009-05-25 Paul Smith <psmith@gnu.org>
126 Reworked the parser for variable assignments to allow multiple
127 modifiers, and in any order. Also allows variable and
128 prerequisites to be modifier names ('export', 'private', etc.)
130 * NEWS: Add notes about user-visible changes.
132 * read.c (struct vmodifiers): Remember what modifiers were seen.
133 (parse_var_assignment): New function to parse variable assignments.
134 (eval): Call the new function. Handle variable assignments earlier.

139 2009-05-24 Paul Smith <psmith@gnu.org>
141 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
142 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
144 2009-03-14 Eli Zaretskii <eliz@gnu.org>
146 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
147 Fixes Savannah bug #25412.
149 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
150 prototype for xmalloc.
151 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
152 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
153 Loop over an array of extensions, instead of duplicating the same
154 code inline. Use SearchPath followed by CreateFile, instead of
155 the obsolete OpenFile. Fixes Savannah bug #17277.
156 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
157 to `find_file'. Fixes Savannah bug #25662.
159 2009-03-07 Eli Zaretskii <eliz@gnu.org>
161 * function.c (func_shell): Don't close pipedes[1] if it is -1.
162 Fixes Savannah bug #20495.
164 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
166 Introduce a new keyword "private" which applies to target-specific
167 variables and prevents their values from being inherited.
169 * variable.h (struct variable): Add private_var flag to each variable.
170 Add a flag to specify which list entry switches to the parent target.

192 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
195 * w32/subproc/build.bat (GCCBuild): Likewise.
197 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
199 * job.c (construct_command_argv_internal): Avoid extra backslash
200 in batch-mode Unixy shells. Under DB_JOBS, display the contents

206 -jN without Unixy shell. Remove obsolete text about not supplying
207 Visual Studio project files (we do supply them). Modify text to
208 prefer GCC builds to MSC builds.
210 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
212 * doc/make.texi (Empty Targets): Fix typo.
214 2008-03-27 Paul Smith <psmith@gnu.org>
216 Fix Savannah bug #22379:
217 * ar.c (ar_glob_match): Zero the allocated structure.
218 * read.c (parse_file_seq): Ditto.
220 2008-03-08 Brian Dessent <brian@dessent.net>
222 * maintMakefile: Update Translation Project location.
224 2008-01-26 Eli Zaretskii <eliz@gnu.org>
226 * variable.c (target_environment): Don't use shell_var if its
227 `value' field is NULL.
229 2007-12-22 Eli Zaretskii <eliz@gnu.org>
231 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
233 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
234 (TEXINFOS): Value changed to `doc/make.texi'.
235 (.SUFFIXES): Use .texi instead of .texinfo.
236 (make.info, make.dvi): Depend on doc/make.texi.
237 (.texi.info): New target, instead of ".texinfo.info". Change -I

239 (.texi): New target, instead of ".texinfo". Change -I switch to
240 $(MAKEINFO) to look in doc/. Use --no-split.
241 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
242 switch to $(MAKEINFO) to look in doc/.
243 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
244 "*.i[0-9][0-9]" (due to --no-split above).
245 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
246 (html, make_1.html): New targets.
247 (.PHONY): Add "html".
248 (.SUFFIXES): Add .html.
250 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
252 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
253 HAVE_DECL_SYS_SIGLIST.
255 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
256 build does not use child_execute_job.
258 * variable.c (define_automatic_variables) [__MSDOS__]: Always
259 export the SHELL environment variable to the child.
261 2007-12-22 Eli Zaretskii <eliz@gnu.org>
263 * config.h.W32: Include sys/types.h.

273 lines", and "command script" to "recipe".
275 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
278 2007-10-27 Bruno Haible <bruno@clisp.org>
280 * remake.c (f_mtime): Print time difference values between 100 and
281 ULONG_MAX in fixed-point notation rather than in exponention notation.
283 2007-10-12 Eli Zaretskii <eliz@gnu.org>
285 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
286 a more complex value than a simple shell: if it's not a default
287 shell now then expand it and see if is a default shell then.
289 2007-10-10 Eli Zaretskii <eliz@gnu.org>
291 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
292 pathnames, with const strings.
293 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
294 from the template (used for building from CVS, not a dist).
296 2007-10-10 Paul Smith <psmith@gnu.org>
298 * make.h: Add a prototype for w32_kill() (change suggested by
299 Yongwei Wu <wuyongwei@gmail.com>).

311 Provided by Diego Biurrun <diego@biurrun.de>
313 2007-09-11 Paul Smith <psmith@gnu.org>
315 * doc/make.texi (Special Variables): Moved this into the "How to
316 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
317 (MAKEFILE_LIST) No longer a section; this was added into the
318 "Special Variables" section.
319 (Rule Introduction): Reference .RECIPEPREFIX.
320 (Simple Makefile): Ditto.
321 (Rule Syntax): Ditto.
322 (Command Syntax): Ditto.
323 (Error Messages): Ditto.
325 2007-09-10 Paul Smith <psmith@gnu.org>
327 * commands.c (print_commands): Don't print an extra line in the
328 command scripts. Prefix the command scripts with cmd_prefix, not \t.
330 * read.c (construct_include_path): Add the full string to the cache; we
331 were chopping the last char.
333 * NEWS: Announce the .RECIPEPREFIX special variable.
334 * variable.c (lookup_special_var): Rename from handle_special_var().
335 (lookup_variable): Call the new name.

340 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
341 * main.c (main): Create the .RECIPEPREFIX special variable.
342 * read.c (eval): Remove the cmd_prefix characters from the command
343 scripts here, so they're not stored in the commands array at all,
344 rather than waiting and stripping them out during command construction.
345 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
347 2007-08-15 Paul Smith <psmith@gnu.org>
349 * doc/make.texi (GNU Free Documentation License): The fdl.texi
350 file has had the section info removed, so add some to make.texi
351 before we include it.
353 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
355 * remake.c (check_dep): Reset the target state for intermediate
356 files. They might have been considered before but not updated
357 then (order-only for example) but they will be this time.
358 Fixes Savannah bug #'s 3330 and 15919.
360 2007-07-21 Eli Zaretskii <eliz@gnu.org>
362 Fix Savannah bug #20549:
363 * function.c (func_shell): Call construct_command_argv with zero
365 * job.c (construct_command_argv_internal): New argument FLAGS; all
367 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
369 * job.h (construct_command_argv_internal): Update prototype.
371 2007-07-13 Paul Smith <psmith@gnu.org>
373 * file.c (expand_deps): Use variable_buffer as the start of the
374 buffer, not the original pointer (in case it was reallocated).
375 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
376 Fixes Savannah bug #20452.
378 2007-07-04 Paul Smith <psmith@gnu.org>
380 * (ALL FILES): Update to GPLv3.
381 * (ALL FILES): Update copyright for 2007.

389 2007-06-13 Paul Smith <psmith@gnu.org>
391 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
392 "Expansion of a deferred"
393 Fixes Savannah bug #20018.
395 * expand.c (variable_expand_for_file): Preserve the value of
396 reading_file rather than setting it to 0 at the end.
397 Fixes Savannah bug #20033.
399 2007-05-11 Paul Smith <psmith@gnu.org>
401 * job.c (new_job): Add debug info to specify where make found the
402 command script it is running to build a target.
403 Fixes Savannah bug #18617.
405 * default.c (default_suffixes,default_suffix_rules,default_variables):
406 Add support for Objective C. Fixes Savannah bug #16389.
407 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
409 * function.c (func_lastword): Initialize p.
411 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
412 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
413 Dave Korn <dave.korn@artimi.com>
415 2007-05-08 Paul Smith <psmith@gnu.org>
417 Fix Savannah bug #19656:
419 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
421 * make.h: Change all case-insensitive string compares to use
422 strcasecmp() (from POSIX). If we don't have that but do have one
423 of the others, define strcasecmp to be one of those instead. If
424 we don't have any, declare a prototype for our own version.
426 * misc.c (strcasecmp): Use this if we can't find any native
427 case-insensitive string comparison function.
428 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
429 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
431 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
432 strcasecmp() instead of stricmp().
433 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
434 instead of strcmpi().
435 * acinclude.m4: Remove the strcasecmp() check from here.
437 2007-03-21 Paul Smith <psmith@gnu.org>
439 * configure.in: Don't turn on case-insensitive file system support
440 if --disable-... is given. Fixes Savannah bug #19348.
442 2007-03-19 Paul Smith <psmith@gnu.org>
444 * ALL: Use the strcache for all file name strings, or other
445 strings which we will never free. The goal is to save memory by
446 avoiding duplicate copies of strings. However, at the moment this
447 doesn't save much memory in most situations: due to secondary
448 expansion we actually save prerequisite lists twice (once before
449 the secondary expansion, and then again after it's been parsed
450 into individual file names in the dep list). We will resolve this
451 in a future change, by doing the parsing up-front for targets
452 where secondary expansion is not set.
454 Moving things into the strcache also allows us to use const
455 pointers in many more places.
457 2007-01-03 Paul Smith <psmith@gnu.org>
459 * make.h (ENULLLOOP): Reset errno after each failed invocation of
460 the function, not just the first. Fixes Savannah bug #18680.
462 2006-11-18 Paul Smith <psmith@gnu.org>
464 * strcache.c (strcache_add_len): Don't allocate a new buffer
465 unless the string is not already nil-terminated. Technically this
466 is a violation of the standard, since we may be passed an array
467 that is not long enough to test one past. However, in make this
468 is never true since we only use nil-terminated strings or
471 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
473 * main.c: New global cmd_prefix, defaults to '\t'.
474 * job.c (construct_command_argv_internal): Use cmd_prefix instead
478 (dir_contents_file_exists_p): Check for an error return from
479 readdir(), just in case.
481 * commands.c: Constified.
482 * default.c: Constified.
483 * expand.c: Constified.
484 * function.c: Partial constification.
485 * variable.c: Partial constification.
486 * vmsify.c: Constification. Hard to test this but I hope I didn't
488 * vpath.c: Partial constification.
489 * w32/pathstuff.c: Partial constification.
491 2006-11-16 Eli Zaretskii <eliz@gnu.org>
493 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
494 backslashes and drive letters as absolute.
496 2006-10-22 Paul Smith <psmith@gnu.org>
498 * main.c (struct command_switch): Use const and void*.
500 2006-10-21 Paul Smith <psmith@gnu.org>
503 * arscan.c: Constified.
505 2006-09-30 Paul Smith <psmith@gnu.org>
507 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
508 point to lastword since the example was updated.
509 Fixes Savannah bug #16304.
510 (Secondary Expansion): Correct example description.
511 Fixes Savannah bug #16468.
512 (Makefile Contents): Clarify that comments cannot appear within
513 variable references or function calls.
514 Fixes Savannah bug #16577.
515 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
516 Fixes Savannah bug #17701.
517 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
518 (Prerequisite Types): Added an example of using order-only
519 prerequisites. Fixes Savannah bug #17880.
520 (Rule Syntax): "lise" -> "list"
521 (Multiple Rules): ... -> @dots{}
522 (Splitting Lines): ditto.
524 * remake.c (update_file_1): Prereqs that don't exist should be
525 considered changed, for the purposes of $?.
526 Fixes Savannah bug #16051.
528 * make.1: Remove extraneous "+".
529 Fixes Savannah bug #16652.
531 2006-09-06 Paul D. Smith <psmith@gnu.org>
533 * configure.in: Include sys/types.h when checking for sys/wait.h.
535 2006-08-18 Eli Zaretskii <eliz@gnu.org>
537 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
540 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
541 Normally, it is defined in config.h.
543 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
546 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define

637 Declare and define sh_chars_sh[].
639 2006-03-23 Paul D. Smith <psmith@gnu.org>
641 * configure.in: Look for build.sh.in in $srcdir so it will be
642 built for remote configurations as well.
644 * Makefile.am: Make sure to clean up build.sh during distclean.
645 Fixes Savannah bug #16166.
647 * misc.c (log_access): Takes a const char *.

667 (die): Cleanup code was removed from here; call the new function.
668 (main): If we are re-execing, clean up the jobserver first so we

680 * dep.h (struct dep): Add the stem field.
681 * misc.c (alloc_dep, free_dep): New functions.
682 (copy_dep_chain): Copy stem.
683 (free_dep_chain): Use free_dep.
684 * read.c (record_files): Store stem in the dependency line.
685 * file.c (expand_deps): Use stem stored in the dependency line. Use

698 (allocated_variable_append): Don't expand the final result.
699 Fixes Savannah bug #15913.
701 2006-03-09 Paul Smith <psmith@gnu.org>
703 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
704 listed non-existent files as changed. Turns out there's a bug in
705 the Linux kernel builds which means that this change causes
706 everything to rebuild every time. We will re-introduce this fix
707 in the next release, to give them time to fix their build system.
708 Fixes Savannah bug #16002.
709 Introduces Savannah bug #16051.
711 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
712 we *don't* find UNIX "/".
713 Reported by David Ergo <david.ergo@alterface.com>

724 to be null; don't core in that case.
726 2006-02-19 Paul D. Smith <psmith@gnu.org>
728 * commands.c (set_file_variables): Realloc, not malloc, the static
729 string values to avoid memory leaks.
731 * expand.c (recursively_expand_for_file): Only set reading_file to
732 an initialized value.
734 * implicit.c (pattern_search): We need to make a copy of the stem
735 if we get it from an intermediate dep, since those get freed.
737 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
739 (enter_file) [VMS]: Ditto.
740 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

746 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
747 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
748 the calls to _beginthreadex.

751 prevent compiler warnings.
753 2006-02-18 Eli Zaretskii <eliz@gnu.org>
755 * job.c (construct_command_argv_internal): Don't create a temporary
756 script/batch file if we are under -n. Call _setmode to switch the
757 script file stream to text mode.
759 2006-02-17 Paul D. Smith <psmith@gnu.org>
761 * variable.c (merge_variable_set_lists): Don't try to merge the
762 global_setlist. Not only is this useless, but it can lead to
763 circularities in the linked list, if global_setlist->next in one
764 list gets set to point to another list which also ends in
766 Fixes Savannah bug #15757.
768 2006-02-15 Paul D. Smith <psmith@gnu.org>
770 Fix for Savannah bug #106.
772 * expand.c (expanding_var): Keep track of which variable we're
773 expanding. If no variable is being expanded, it's the same as
775 * make.h (expanding_var): Declare it.
776 * expand.c (recursively_expand_for_file): Set expanding_var to the
777 current variable we're expanding, unless there's no file info in
778 it (could happen if it comes from the command line or a default
779 variable). Restore it before we exit.
780 * expand.c (variable_expand_string): Use the expanding_var file
781 info instead of the reading_file info.
782 * function.c (check_numeric): Ditto.
784 (func_wordlist): Ditto.

787 (handle_function): Ditto.
789 2006-02-14 Paul D. Smith <psmith@gnu.org>
791 * read.c (eval): Even if the included filenames expands to the
792 empty string we still need to free the allocated buffer.
794 * implicit.c (pattern_search): If we allocated a variable set for
795 an impossible file, free it.
796 * variable.c (free_variable_set): New function.
797 * variable.h: Declare it.
799 * read.c (read_all_makefiles): Makefile names are kept in the
800 strcache, so there's never any need to alloc/free them.
803 * main.c (main): Add "archives" to the .FEATURES variable if
804 archive support is enabled.
805 * doc/make.texi (Special Variables): Document it.
807 2006-02-13 Paul D. Smith <psmith@gnu.org>
809 * implicit.c (pattern_search): Add checking for DOS pathnames to
810 the pattern rule target LASTSLASH manipulation.
811 Fixes Savannah bug #11183.
813 2006-02-11 Paul D. Smith <psmith@gnu.org>
815 * (ALL FILES): Updated copyright and license notices.
817 2006-02-10 Paul D. Smith <psmith@gnu.org>
819 A new internal capability: the string cache is a read-only cache
820 of strings, with a hash table interface for fast lookup. Nothing
821 in the cache will ever be freed, so there's no need for reference
822 counting, etc. This is the beginning of a full solution for
823 Savannah bug #15182, but for now we only store makefile names here.
825 * strcache.c: New file. Implement a read-only string cache.
826 * make.h: Add prototypes for new functions.
827 * main.c (initialize_global_hash_tables): Initialize the string cache.
828 (print_data_base): Print string cache stats.
829 * read.c (eval_makefile): Use the string cache to store makefile

834 * dir.c (dir_contents_file_exists_p): Don't opendir if the
835 directory time stamp didn't change, except on FAT filesystems.
836 Suggested by J. David Bryan <jdbryan@acm.org>.
838 2006-02-09 Paul D. Smith <psmith@gnu.org>
840 * function.c (func_or): Implement a short-circuiting OR function.
841 (func_and): Implement a short-circuiting AND function.
842 (function_table_init): Update the table with the new functions.
843 * doc/make.texi (Conditional Functions): Changed the "if" section
844 to one on general conditional functions. Added documentation for
845 $(and ...) and $(or ...) functions.
846 * NEWS: Note new $(and ...) and $(or ...) functions.

853 one in struct file. Fixes Savannah bug #15641.
855 2006-02-06 Paul D. Smith <psmith@gnu.org>
857 * vpath.c (selective_vpath_search): If the file we find has a
858 timestamp from -o or -W, use that instead of the real time.
859 * remake.c (f_mtime): If the mtime is a special token from -o or
860 -W, don't overwrite it with the real mtime.
861 Fixes Savannah bug #15341.

871 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
872 * README.cvs: Updates for building from CVS.
874 2006-02-05 Paul D. Smith <psmith@gnu.org>
876 * file.c (enter_file): Keep track of the last double_colon entry,
877 to avoid walking the list every time we want to add a new one.
878 Fixes Savannah bug #15533.
879 * filedef.h (struct file): Add a new LAST pointer.
881 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
882 the comparison. For 64-bits systems the result of the subtraction
883 might not fit into an int. Use comparison instead.

907 2006-01-21 Eli Zaretskii <eliz@gnu.org>
909 * remake.c (update_goal_chain): Set g->changed instead of
910 incrementing it, as it is only 8-bit wide, and could overflow if
911 many commands got started in update_file.
913 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
915 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

936 all callers changed. Don't close the temporary file; return its
937 file descriptor instead. New arg FD allows to return the file
939 (construct_command_argv_internal): Use _fdopen instead of fopen to

972 handling of backslash-newline sequences. Mention the differences
973 on MS-DOS and MS-Windows.
975 * NEWS: More details about building the MinGW port and a pointer
976 to README.W32. Fix the section name that describes the new
977 backward-incompatible processing of backslash-newline sequences.
978 The special processing of SHELL set to "cmd" is only relevant to
979 MS-Windows, not MS-DOS.
981 2005-12-17 Eli Zaretskii <eliz@gnu.org>
983 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
984 to DWORD, to avoid compiler warnings.

1006 * make.1: Fix some display errors and document all existing options.
1007 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1009 2005-12-11 Paul D. Smith <psmith@gnu.org>
1011 * implicit.c (pattern_search): If 2nd expansion is not set for
1012 this implicit rule, replace the pattern with the stem directly,
1013 and don't re-expand the variable list. Along with the other
1014 .SECONDEXPANSION changes below, fixes bug #13781.
1016 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1018 * implicit.c (pattern_search): Mark other files that this rule
1019 builds as targets so that they are not treated as intermediates

1084 2005-09-26 Paul D. Smith <psmith@gnu.org>
1086 * job.c (construct_command_argv_internal): If the line is empty
1087 remember to free the temporary argv strings.
1090 2005-09-16 Paul D. Smith <psmith@gnu.org>
1092 * job.c (start_job_command): The noerror flag is a boolean (single
1093 bit); set it appropriately.
1094 Reported by Mark Eichin <eichin@metacarta.com>
1096 2005-08-29 Paul D. Smith <psmith@gnu.org>
1098 * function.c (func_error): On Windows, output from $(info ...)
1099 seems to come in the wrong order. Try to force it with fflush().
1101 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1103 * read.c (record_files): Move code that sets stem for static
1104 pattern rules out of the if (!two_colon) condition so it is
1105 also executed for two-colon rules. Fixes Savannah bug #13881.
1107 2005-08-08 Paul D. Smith <psmith@gnu.org>
1109 * make.h: Don't test that __STDC__ is non-0. Some compilers
1110 (Windows for example) set it to 0 to denote "ISO C + extensions".
1113 2005-08-07 Paul D. Smith <psmith@gnu.org>
1115 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1116 conditional (slightly different version of a fix from Eli).
1118 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1119 If make is running in parallel without -k and two jobs die in a
1120 row, but not too close to each other, then make will quit without
1121 waiting for the rest of the jobs to die.
1123 * main.c (die): Don't reset err before calling reap_children() the
1124 second time: we still want it to be in the error condition.
1125 * job.c (reap_children): Use a static variable, rather than err,
1126 to control whether or not the error message should be printed.
1128 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1130 * w32/subproc/sub_proc.c: Include signal.h.
1131 (process_pipe_io, process_file_io): Pass a pointer to a local
1132 DWORD variable to GetExitCodeProcess. If the exit code is
1133 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1135 * job.c [WINDOWS32]: Include windows.h.
1136 (main_thread) [WINDOWS32]: New global variable.
1137 (reap_children) [WINDOWS32]: Get the handle for the main thread
1138 and store it in main_thread.
1140 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1141 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1142 doing anything else. When we are done, close the main thread
1143 handle and exit with status 130.
1145 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1147 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1150 * main.c (find_and_set_default_shell): If found a DOSish shell,
1151 set sh_found and the value of default_shell, and report the
1152 findings in debug mode.
1154 * job.c (construct_command_argv_internal): Check unixy_shell, not
1155 no_default_sh_exe, to decide whether to use Unixy or DOSish
1158 * README.W32: Update with info about the MinGW build.
1160 * build_w32.bat: Support MinGW.
1162 * w32/subproc/build.bat: Likewise.
1164 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1165 printing DWORD args.
1167 * function.c (windows32_openpipe): Fix format strings for printing
1170 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1172 (start_job_command): Fix format string for printing the result of
1174 (start_job_command) [WINDOWS32]: Do not define.
1175 (exec_command): Fix format string for printing HANDLE args.
1177 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1178 to avoid compiler warnings.
1179 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1180 (Note: some of these fixes were submitted independently by J. Grant)
1182 2005-07-30 J. Grant <jg@jguk.org>
1184 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1185 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1186 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1188 2005-07-15 Paul Smith <psmith@gnu.org>
1190 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1191 we don't have a POSIX shell, then revert to the old
1192 backslash-newline behavior (where they are stripped).
1195 2005-07-08 Paul D. Smith <psmith@gnu.org>
1197 * config.h.W32.template: Reorder to match the standard config.h,
1198 for easier comparisons.
1199 From J. Grant <jg@jguk.org>
1201 * maintMakefile: Remove .dep_segment before overwriting it, in
1202 case it's not writable or noclobber is set.
1203 * expand.c (variable_expand_string): Cast result of pointer
1204 arithmetic to avoid a warning.
1205 * main.c (switches): Add full-fledged final initializer.
1207 2005-07-06 Paul D. Smith <psmith@gnu.org>
1209 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1210 * signame.c (strsignal): If we found _sys_siglist[] or
1211 __sys_siglist[] use those instead of sys_siglist[].
1212 From Albert Chin <china@thewrittenword.com>
1214 2005-07-04 Paul D. Smith <psmith@gnu.org>
1216 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1217 globfree(); set up to use the GNU versions.
1218 From Martin Zinser <zinser@zinser.no-ip.info>
1220 2005-07-03 Paul D. Smith <psmith@gnu.org>
1222 From J. Grant <jg@jguk.org>:
1224 * README.W32.template: Update the Windows and tested MSVC versions.
1225 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1226 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1227 * build_w32.bat: Ditto.
1228 * w32/subproc/build.bat: Ditto.
1230 2005-06-28 Paul D. Smith <psmith@gnu.org>
1232 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1233 declaration was checked but not present.
1235 2005-06-27 Paul D. Smith <psmith@gnu.org>
1237 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1238 to unsigned long. Fixes Savannah bug #13550.
1240 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1241 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1242 Fixes Savannah bug #13551.
1244 2005-06-26 Paul D. Smith <psmith@gnu.org>
1246 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1247 it if ANSI_STRING is not set.
1249 2005-06-25 Paul D. Smith <psmith@gnu.org>
1251 * read.c (eval): If no filenames are passed to any of the
1252 "include" variants, don't print an error.
1253 * doc/make.texi (Include): Document this.
1254 Fixes Savannah bug #1761.
1256 * job.c (construct_command_argv_internal): Sanitize handling of
1257 backslash/newline pairs according to POSIX: that is, keep the
1258 backslash-newline in the command script, but remove a following
1259 TAB character, if present. In the fast path, make sure that the
1260 behavior matches what the shell would do both inside and outside
1261 of quotes. In the slow path, quote the backslash and put a
1262 literal newline in the string.
1263 Fixes Savannah bug #1332.
1264 * doc/make.texi (Execution): Document the new behavior and give
1266 * NEWS: Make a note of the new behavior.
1268 * make.h [WINDOWS32]: #include <direct.h>.
1269 Fixes Savannah bug #13478.
1271 * remake.c (name_mtime): If the stat() of a file fails and the -L
1272 option was given and the file is a symlink, take the best mtime of
1273 the symlink we can get as the mtime of the file and don't fail.
1274 Fixes Savannah bug #13280.
1276 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1277 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1278 inside a variable reference. Make this function static as it's
1280 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1281 parsing an unexpanded line looking for semicolons.
1282 Fixes Savannah bug #1454.
1283 * misc.c (remove_comments): Move this to read.c and make it static
1284 as it's only used there. Call find_char_unquote() with new arg.
1285 * make.h: Remove prototypes for find_char_unquote() and
1286 remove_comments() since they're static now.
1288 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1289 its export flag and obtain its value. When we need to re-exec,
1290 increment the value and add it into the environment.
1291 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1292 * NEWS: Mention MAKE_RESTARTS.
1293 * main.c (always_make_set): New variable. Change the -B option to
1294 set this one instead.
1295 (main): When checking makefiles, only set always_make_flag if
1296 always_make_set is set AND the restarts flag is 0. When building
1297 normal targets, set it IFF always_make_set is set.
1298 (main): Avoid infinite recursion with -W, too: only set what-if
1299 files to NEW before we check makefiles if we've never restarted
1300 before. If we have restarted, set what-if files to NEW _after_ we
1302 Fixes Savannah bug #7566:
1304 2005-06-17 Paul D. Smith <psmith@gnu.org>
1306 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1307 in the prerequisites list.
1309 2005-06-12 Paul D. Smith <psmith@gnu.org>
1311 Fix Savannah bug # 1328.
1313 * configure.in: Check for atexit().
1314 * misc.c (close_stdout): Test stdout to see if writes to it have
1315 failed. If so, be sure to exit with a non-0 error code. Based on
1316 code found in gnulib.
1317 * make.h: Prototype.
1318 * main.c (main): Install close_stdout() with atexit().
1320 2005-06-10 Paul D. Smith <psmith@gnu.org>
1322 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1324 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1325 headers; make vmsWaitForChildren() static; extern vmsify().
1326 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1327 Don't create child_execute_job() here (it's in vmsjobs.c).
1328 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1330 2005-06-09 Paul D. Smith <psmith@gnu.org>
1332 * variable.c (push_new_variable_scope): File variables point
1333 directly to the global_setlist variable. So, inserting a new
1334 scope in front of that has no effect on those variables: they
1335 don't go through current_variable_set_list. If we're pushing a
1336 scope and the current scope is global, push it "the other way" so
1337 that the new setlist is in the global_setlist variable, and
1338 next points to a new setlist with the global variable set.
1339 (pop_variable_scope): Properly undo a push with the new
1341 Fixes Savannah bug #11913.
1343 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1345 * job.c (reap_children): Don't die of the command failed but
1346 the dontcare flag is set. Fixes Savannah bug #13216.
1348 * implicit.c (pattern_search): When creating a target from
1349 an implicit rule match, lookup pattern target and set precious
1350 flag in a newly created target. Fixes Savannah bug #13218.
1352 2005-05-13 Paul D. Smith <psmith@gnu.org>
1354 Implement "if... else if... endif" syntax.
1356 * read.c (eval): Push all checks for conditional words ("ifeq",
1357 "else", etc.) down into the conditional_line() function.
1358 (conditional_line): Rework to allow "else if..." clause. New
1359 return value -2 for lines which are not conditionals. The
1360 ignoring flag can now also be 2, which means "already parsed a
1361 true branch". If that value is seen no other branch of this
1362 conditional can be considered true. In the else parsing if there
1363 is extra text after the else, invoke conditional_line()
1364 recursively to see if it's another conditional. If not, it's an
1365 error. If so, raise the conditional value to this level instead
1366 of creating a new conditional nesting level. Special check for
1367 "else" and "endif", which aren't allowed on the "else" line.
1368 * doc/make.texi (Conditional Syntax): Document the new syntax.
1370 2005-05-09 Paul D. Smith <psmith@gnu.org>
1372 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1373 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1374 recurses to the w32 directory, even on non-Windows systems. Use
1375 the method suggested in the automake manual.
1376 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1377 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1379 2005-05-07 Paul D. Smith <psmith@gnu.org>
1381 * main.c (die): If we're dying with a fatal error (not that a
1382 command has failed), write back any leftover tokens before we go.
1384 * job.c (set_child_handler_action_flags): If there are jobs
1385 waiting for the load to go down, set an alarm to go off in 1
1386 second. This allows us to wake up from a potentially long-lasting
1387 read() and start a new job if the load has gone down. Turn it off
1389 (job_noop): Dummy signal handler function.
1390 (new_job): Invoke it with the new semantics.
1392 * docs/make.texi: Document secondary expansion. Various cleanups
1395 2005-05-03 Paul D. Smith <psmith@gnu.org>
1397 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1398 the targets which are to ultimately be made are called "goals";
1399 see the GNU make manual. Also, MAKECMDGOALS, etc.
1401 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1402 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1403 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1405 2005-05-02 Paul D. Smith <psmith@gnu.org>
1407 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1408 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1409 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1410 functions to vmsjobs.c. #include it into jobs.c.
1412 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1413 jobserver tokens. I found that this happens when an exported
1414 recursive variable contains a $(shell ...) function reference: in
1415 this situation we could "forget" to write back a token.
1417 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1418 we have. It's not reliable to depend on the number of children in
1419 our linked list so keep a separate count.
1420 (new_job): Check jobserver_tokens rather than children &&
1421 waiting_jobs. Increment jobserver_tokens when we get one.
1422 (free_child): If jobserver_tokens is 0, internal error. If it's
1423 >1, write a token back to the jobserver pipe (we don't write a
1424 token for the "free" job). Decrement jobserver_tokens.
1426 * main.c: Add variable master_job_slots.
1427 (main): Set it to hold the number of jobs requested if we're the
1428 master process, when using the jobserver.
1429 (die): Sanity checks: first test jobserver_tokens to make sure
1430 this process isn't holding any tokens we didn't write back.
1431 Second, if master_job_slots is set count the tokens left in the
1432 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1434 2005-04-24 Paul D. Smith <psmith@gnu.org>
1436 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1437 with -l# can lose jobserver tokens, because waiting jobs are not
1438 consulted properly when checking for the "free" token.
1440 * job.c (free_child): Count waiting_jobs as having tokens.
1441 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1442 handle jobs waiting for the load to drop.
1444 2005-04-23 Paul D. Smith <psmith@gnu.org>
1446 * main.c (main): Be careful to not core if a variable setting in
1447 the environment doesn't contain an '='. This is illegal but can
1448 happen in broken setups.
1449 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1451 2005-04-12 Paul D. Smith <psmith@gnu.org>
1453 The second expansion feature causes significant slowdown. Timing
1454 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1455 read the makefile before the feature, to 11+s to do the same
1456 operations after the feature. Additionally, memory usage
1457 increased drastically. To fix this I added some intelligence that
1458 avoids the overhead of the second expansion unless it's required.
1460 * dep.h: Add a new boolean field, need_2nd_expansion.
1462 * read.c (eval): When creating the struct dep for the target,
1463 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1464 (record_files): If there's a "%" in a static pattern rule, it gets
1465 converted to "$*" so set need_2nd_expansion to 1.
1467 * file.c (expand_deps): Rework to be more efficient. Only perform
1468 initialize_file_variables(), set_file_variables(), and
1469 variable_expand_for_file() if the need_2nd_expansion is set.
1471 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1472 (pattern_search): Ditto.
1473 * main.c (handle_non_switch_argument): Ditto.
1475 * read.c (read_all_makefiles): Ditto.
1476 (eval_makefile): Ditto.
1478 2005-04-07 Paul D. Smith <psmith@gnu.org>
1480 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1481 * variable.c (sync_Path_environment): Ditto.
1482 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1484 * main.c (main): Define the .FEATURES variable.
1485 * NEWS: Announce .FEATURES.
1486 * doc/make.texi (Special Variables): Document .FEATURES.
1488 * remake.c (check_dep): If a file is .PHONY, update it even if
1489 it's marked intermediate. Fixes Savannah bug #12331.
1491 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1493 * file.c (expand_deps): Factor out the second expansion and
1494 prerequisite line parsing logic from snap_deps().
1496 * file.c (snap_deps): Use expand_deps(). Expand and parse
1497 prerequisites of the .SUFFIXES special target first. Fixes
1498 Savannah bug #12320.
1500 2005-03-13 Paul D. Smith <psmith@gnu.org>
1502 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1505 2005-03-11 Paul D. Smith <psmith@gnu.org>
1507 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1508 available, not undefined (from Earnie Boyd).
1510 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1512 * implicit.c (pattern_search): Mark an intermediate target as
1513 precious if it happened to be a prerequisite of some (other)
1514 target. Fixes Savannah bug #12267.
1516 2005-03-09 Paul D. Smith <psmith@gnu.org>
1518 * read.c (eval_makefile): Add alloca(0).
1519 (eval_buffer): Ditto.
1521 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1523 * main.c (main): Use o_file instead of o_default when defining
1524 the .DEFAULT_TARGET special variable.
1525 * read.c (eval): Use define_variable_global() instead of
1526 define_variable() when setting new value for the .DEFAULT_TARGET
1527 special variable. Fixes Savannah bug #12266.
1529 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1531 * imlicit.c (pattern_search): Mark files for which an implicit
1532 rule has been found as targets. Fixes Savannah bug #12202.
1534 2005-03-04 Paul D. Smith <psmith@gnu.org>
1537 * doc/make.texi (Automatic Variables): Document $|.
1539 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1541 * read.c (record_files): Instead of substituting % with
1542 actual stem value in dependency list replace it with $*.
1543 This fixes stem triple expansion bug.
1545 * implicit.c (pattern_search): Copy stem to a separate
1546 buffer and make it a properly terminated string. Assign
1547 this buffer instead of STEM (which is not terminated) to
1548 f->stem. Instead of substituting % with actual stem value
1549 in dependency list replace it with $*. This fixes stem
1550 triple expansion bug.
1552 2005-03-01 Paul D. Smith <psmith@gnu.org>
1554 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1555 on Windows, as it takes a handle not a pid. Just exit.
1556 Fix from patch #3679, provided by Alessandro Vesely.
1558 * configure.in: Update check for sys_siglist[] from autoconf manual.
1559 * signame.c (strsignal): Update to use the new autoconf macro.
1561 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1563 * read.c (record_files): Add a check for the list of prerequisites
1564 of a static pattern rule being empty. Fixes Savannah bug #12180.
1566 2005-02-28 Paul D. Smith <psmith@gnu.org>
1568 * doc/make.texi (Text Functions): Update docs to allow the end
1569 ordinal for $(wordlist ...) to be 0.
1570 * function.c (func_wordlist): Fail if the start ordinal for
1571 $(wordlist ...) is <1. Matches documentation.
1572 Resolves Savannah support request #103195.
1574 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1575 previously we were stopping when !-q, exactly the opposite. This
1576 has been wrong since version 1.34, in 1994!
1577 (update_file): If we got an error don't break out to run more
1578 double-colon rules: just return immediately.
1579 Fixes Savannah bug #7144.
1581 2005-02-27 Paul D. Smith <psmith@gnu.org>
1583 * misc.c (end_of_token): Make argument const.
1584 * make.h: Update prototype.
1586 * function.c (abspath, func_realpath, func_abspath): Use
1587 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1588 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1589 * read.c (record_files): Ditto.
1590 * variable.c (do_variable_definition): Ditto.
1592 * function.c (func_error): Create a new function $(info ...) that
1593 simply prints the message to stdout with no extras.
1594 (function_table_init): Add new function to the table.
1595 * NEWS: Add $(info ...) reference.
1596 * doc/make.texi (Make Control Functions): Document it.
1598 New feature: if the system supports symbolic links, and the user
1599 provides the -L/--check-symlink-time flag, then use the latest
1600 mtime between the symlink(s) and the target file.
1602 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1603 readlink(). If both are available, define MAKE_SYMLINKS.
1604 * main.c: New variable: check_symlink_flag.
1605 (usage): Add a line for -L/--check-symlink-times to the help string.
1606 (switches): Add -L/--check-symlink-times command line argument.
1607 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1608 print a warning and disable it again.
1609 * make.h: Declare check_symlink_flag.
1610 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1611 if the file is a symlink then check each link in the chain and
1612 choose the NEWEST mtime we find as the mtime for the file. The
1613 newest mtime might be the file itself!
1614 * NEWS: Add information about this new feature.
1615 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1617 Avoid core dumps described in Savannah bug # 12124:
1619 * file.c: New variable snapped_deps remember whether we've run
1621 (snap_deps): Set it.
1622 * filedef.h: Extern it.
1623 * read.c (record_files): Check snapped_deps; if it's set then
1624 we're trying to eval a new target/prerequisite relationship from
1625 within a command script, which we don't support. Fatal.
1627 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1629 Implementation of the .DEFAULT_TARGET special variable.
1631 * read.c (eval): If necessary, update default_target_name when
1633 * read.c (record_files): Update default_target_file if
1634 default_target_name has changed.
1635 * main.c (default_target_name): Define.
1636 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1637 default_target_name is set use default_target_file as a root
1639 * filedef.h (default_target_name): Declare.
1640 * dep.h (free_dep_chain):
1641 * misc.c (free_dep_chain): Change to operate on struct nameseq
1642 and change name to free_ns_chain.
1643 * file.c (snap_deps): Update to use free_ns_chain.
1645 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1647 Implementation of the second expansion in explicit rules,
1648 static pattern rules and implicit rules.
1650 * read.c (eval): Refrain from chopping up rule's dependencies.
1651 Store them in a struct dep as a single dependency line. Remove
1652 the code that implements SySV-style automatic variables.
1654 * read.c (record_files): Adjust the code that handles static
1655 pattern rules to expand all percents instead of only the first
1656 one. Reverse the order in which dependencies are stored so that
1657 when the second expansion reverses them again they appear in
1658 the makefile order (with some exceptions, see comments in
1659 the code). Remove the code that implements SySV-style automatic
1662 * file.c (snap_deps): Implement the second expansion and chopping
1663 of dependency lines for explicit rules.
1665 * implicit.c (struct idep): Define an auxiliary data type to hold
1666 implicit rule's dependencies after stem substitution and
1669 * implicit.c (free_idep_chain): Implement.
1671 * implicit.c (get_next_word): Implement helper function for
1672 parsing implicit rule's dependency lines into words taking
1673 into account variable expansion requests. Used in the stem
1676 * implicit.c (pattern_search): Implement the second expansion
1677 for implicit rules. Also fixes bug #12091.
1679 * commands.h (set_file_variables): Declare.
1680 * commands.c (set_file_variables): Remove static specifier.
1682 * dep.h (free_dep_chain): Declare.
1683 * misc.c (free_dep_chain): Implement.
1685 * variable.h (variable_expand_for_file): Declare.
1686 * expand.c (variable_expand_for_file): Remove static specifier.
1688 * make.h (strip_whitespace): Declare.
1689 * function.c (strip_whitespace): Remove static specifier.
1691 2005-02-26 Paul D. Smith <psmith@gnu.org>
1693 * main.c (main): Check for ferror() when reading makefiles from stdin.
1694 Apparently some shells in Windows don't close pipes properly and
1697 2005-02-24 Jonathan Grant <jg@jguk.org>
1699 * configure.in: Add MinGW configuration options, and extra w32 code
1701 * Makefile.am: Add MinGW configuration options, and extra w32 code
1703 * main.c: Determine correct program string (after last \ without .exe).
1704 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1706 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1707 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1708 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1709 environment support.
1711 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1713 * function.c (func_shell): When initializing error_prefix, check
1714 that reading file name is not null. This fixes long-standing
1715 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1717 2005-02-09 Paul D. Smith <psmith@gnu.org>
1719 * maintMakefile: Update the CVS download URL to simplify them.
1720 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1721 downloading the .texi files from Savannah now.
1723 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1725 * main.c (handle_non_switch_argument): Only add variables to
1726 command_variables if they're not already there: duplicate settings
1727 waste space and can be confusing to read.
1729 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1730 this header is never included by non-WINDOWS32 code, and it
1731 requires <config.h> to define which isn't always included first.
1733 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1734 testing MINGW32 versions.
1736 * main.c (log_working_directory): flush stdout to be sure the WD
1737 change is printed before any stderr messages show up.
1739 2005-02-01 Paul D. Smith <psmith@gnu.org>
1741 * maintMakefile (po_repo): Update the GNU translation site URL.
1743 2004-12-01 Paul D. Smith <psmith@gnu.org>
1745 * main.c (main): Change char* env_shell to struct variable shell_var.
1746 * variable.c (target_environment): Use new shell_var.
1748 2004-11-30 Paul D. Smith <psmith@gnu.org>
1750 * configure.in: The old way we avoided creating build.sh from
1751 build.sh.in before build.sh.in exists doesn't work anymore; we
1752 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1753 the help!). This also keeps automake from complaining.
1754 * Makefile.am (README): Add a dummy target so automake won't
1755 complain that this file doesn't exist when we checkout from CVS.
1756 * maintMakefile (.dep_segment): Rewrite this rule since newer
1757 versions of automake don't provide DEP_FILES.
1759 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1761 Implementation of `realpath' and `abspath' built-in functions.
1763 * configure.in: Check for realpath.
1764 * function.c (abspath): Return an absolute file name that does
1765 not contain any `.' or `..' components, nor repeated `/'.
1766 * function.c (func_abspath): For each name call abspath.
1767 * function.c (func_realpath): For each name call realpath
1768 from libc or delegate to abspath if realpath is not available.
1769 * doc/make.texi (Functions for File Names): Document new functions.
1770 * doc/make.texi (Quick Reference): Ditto.
1772 2004-11-28 Paul D. Smith <psmith@gnu.org>
1774 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1775 arguments. Fixes bug #10252.
1777 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1779 * main.c (main): Set SHELL to v_noexport by default. Remember the
1780 original environment setting of SHELL in the env_shell variable.
1781 * main.h: Export new env_shell variable.
1782 * variable.c (target_environment): If we find a v_noexport
1783 variable for SHELL, add a SHELL variable with the env_shell value.
1784 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1785 * doc/make.texi (Variables/Recursion): Ditto.
1787 2004-11-28 Paul D. Smith <psmith@gnu.org>
1789 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1790 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1791 Patch by Alessandro Vesely.
1793 2004-11-12 Paul D. Smith <psmith@gnu.org>
1795 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1796 the command line if it's inside a string.
1797 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1799 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1801 * function.c (func_lastword): New function: return last word
1802 from the list of words.
1803 * doc/make.texi: Document $(lastword ). Fix broken links in
1804 Quick Reference section.
1806 2004-10-06 Paul D. Smith <psmith@gnu.org>
1808 Apply patch from Alessandro Vesely, provided with bug # 9748.
1809 Fix use of tmpnam() to work with Borland C.
1811 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1812 construction of a temporary filename, and call new function
1813 create_batch_filename().
1814 (create_batch_filename) [WINDOWS32]: New function to create a
1817 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1819 * read.c (record_target_var): Expand simple pattern-specific
1821 * variable.c (initialize_file_variables): Do not expand simple
1822 pattern-specific variable.
1824 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1826 * remake.c (update_file_1): When rebuilding makefiles inherit
1827 dontcare flag from a target that triggered update.
1829 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1831 * variable.c (initialize_file_variables): Mark pattern-specific
1832 variable as a per-target and copy export status.
1834 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1836 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1838 * implicit.c (pattern_search): When considering an implicit rule's
1839 prerequisite check that it is actually a target rather then
1840 just an entry in the file hashtable.
1842 2004-09-21 Paul D. Smith <psmith@gnu.org>
1844 * read.c (readstring): Fix some logic errors in backslash handling.
1845 (eval): Remove some unnecessary processing in buffer handling.
1846 (record_target_var): Assert that parse_variable_definition() succeeded.
1847 Reported by: Markus Mauhart <qwe123@chello.at>.
1849 * misc.c: Removed the sindex() function. All instances of this
1850 function were trivially replaceable by the standard strstr()
1851 function, and that function will always have better (or certainly
1852 no worse) performance than the very simple-minded algorithm
1853 sindex() used. This can matter with complex makefiles.
1854 * make.h: Remove the prototype for sindex().
1855 * function.c (subst_expand): Convert sindex() call to strstr().
1856 This means we no longer need to track the TLEN value so remove that.
1857 (func_findstring): Convert sindex() to strstr().
1858 * commands.c (chop_commands): Convert sindex() calls to strstr().
1859 Suggested by: Markus Mauhart <qwe123@chello.at>.
1861 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1862 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1863 If SHELL is set to CMD.EXE then assume it's batch-mode and
1864 non-unixy. I wrote the code differently from the patch, though,
1865 to make it safer. This also resolves bug #9174.
1867 2004-09-20 Paul D. Smith <psmith@gnu.org>
1869 * expand.c (variable_expand_string): Modify to invoke
1870 patsubst_expand() instead of subst_expand(); the latter didn't
1871 handle suffix patterns correctly.
1872 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1873 was used only from variable_expand_string() and is no longer used
1875 (func_subst): Ditto, on call to subst_expand().
1876 (patsubst_expand): Require the percent pointers to point to the
1877 character after the %, not to the % itself.
1878 * read.c (record_files): New call criteria for patsubst_expand().
1879 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1880 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1882 2004-09-19 Paul D. Smith <psmith@gnu.org>
1884 * function.c (subst_expand): Fix a check in by_word: look for a
1885 previous blank if we're beyond the beginning of the string, not
1886 the beginning of the word.
1887 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1889 2004-05-16 Paul D. Smith <psmith@gnu.org>
1891 * remake.c (update_goal_chain): Change the argument specifying
1892 whether we're rebuilding makefiles to be a global variable,
1893 REBUILDING_MAKEFILES.
1894 (complain): Extract the code that complains about no rules to make
1895 a target into a separate function.
1896 (update_file_1): If we tried to rebuild a file during the makefile
1897 rebuild phase and it was dontcare, then no message was printed.
1898 If we then try to build the same file during the normal build,
1899 print a message this time.
1900 (remake_file): Don't complain about un-remake-able files when
1901 we're rebuilding makefiles.
1903 2004-05-11 Paul D. Smith <psmith@gnu.org>
1905 * job.c (construct_command_argv_internal): OS/2 patches from
1906 Andreas Buening <andreas.buening@nexgo.de>.
1908 2004-05-10 Paul D. Smith <psmith@gnu.org>
1910 * remake.c (update_file): Don't walk the double-colon chain unless
1911 this is a double-colon rule. Fix suggested by Boris Kolpackov
1912 <boris@kolpackov.net>.
1914 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1915 * readme.vms: New section describing OpenVMS support and issues.
1916 * default.c (default_variables): Add support for IA64.
1917 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1918 without some privilege aborts make with the error
1919 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1920 pressing Ctrl+Y and the input device is no terminal. The change
1921 catches this error and just continues.
1923 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1925 2004-04-25 Paul D. Smith <psmith@gnu.org>
1927 * commands.c (set_file_variables): Set $< properly in the face of
1928 order-only prerequisites.
1929 Patch from Boris Kolpackov <boris@kolpackov.net>
1931 2004-04-21 Bob Byrnes <byrnes@curl.com>
1933 * main.c (main): Notice failures to remake makefiles.
1935 2004-03-28 Paul D. Smith <psmith@gnu.org>
1937 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1939 * job.c: No default shell for RISC OS.
1940 (load_too_high): Hard-code the return to 1.
1941 (construct_command_argv_internal): No sh_chars or sh_cmds.
1942 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1944 2004-03-20 Paul D. Smith <psmith@gnu.org>
1946 * variable.c (do_variable_definition): Don't append from the
1947 global set if a previous non-appending target-specific variable
1948 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1951 * expand.c (reference_variable): Don't give up on variables with
1952 no value that have the target-specific append flag set: they might
1953 have a value after all. Reported by Oliver Schmidt
1954 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1955 <nikulin@dx1cmd.inp.nsk.su>.
1957 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1958 refer to absolute pathnames in directories that don't exist: some
1959 portion of the makefile could create those directories before we
1960 match the pattern. Fixes bugs #775 and #108.
1962 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1964 * main.c (main): Free makefile_mtimes if we have any.
1965 * README.W32.template: Update documentation for the current status
1966 of the MS-Windows port.
1967 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1968 environment variable is sometimes already defined which causes the
1970 * main.c (debug_signal_handler): Only define this function if
1971 SIGUSR1 is available.
1973 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1975 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1976 * README.OS2.template: Documentation updates.
1977 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1978 link line for safety.
1979 * maintMakefile (build.sh.in): Remove an extraneous ")".
1980 * job.c (child_execute_job): Close saved FDs.
1981 * job.c (exec_command) [OS/2]: exec_command(): If the command
1982 can't be exec'ed and if the shell is not Unix-sh, then try again
1983 with argv = { "cmd", "/c", ... }. Normally, this code is never
1984 reached for the cmd shell unless the command really doesn't exist.
1985 (construct_command_argv_internal) [OS/2]: The code for cmd
1986 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1987 The CMD builtin commands are case insensitive so use strcasecmp().
1989 2004-03-19 Paul D. Smith <psmith@gnu.org>
1991 * read.c (do_define): Re-order line counter increment so the count
1992 is accurate (we were losing one line per define). Reported by
1993 Dave Yost <Dave@Yost.com>.
1995 2004-03-06 Paul D. Smith <psmith@gnu.org>
1997 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1999 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2000 * misc.c (message,error,fatal): Ditto.
2001 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2002 * config.h.W32.template: Ditto.
2003 * config.h-vms.template: Ditto.
2004 * config.ami.template: Ditto.
2006 2004-03-04 Paul D. Smith <psmith@gnu.org>
2008 * README.template: Add a note about broken /bin/sh on SunOS
2009 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2011 * misc.c (message, error, fatal): Don't use "..." if we're using
2012 varargs. ansi2knr should handle this but it doesn't work: it
2013 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2014 done. On many systems (SunOS for example) va_dcl is a #define.
2015 So, force the use of the non-"..." version on pre-ANSI compilers.
2017 * maintMakefile (sign-dist): Create some rules to help automate
2018 the new GNU ftp upload method.
2020 2004-02-24 Paul D. Smith <psmith@gnu.org>
2022 * config.h.W32.template: Add HAVE_STDARG_H
2023 * config.h-vms.template: Ditto.
2024 * config.ami.template: Ditto.
2026 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2028 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2029 * build_w32.bat: Remove extra "+".
2031 2004-02-23 Paul D. Smith <psmith@gnu.org>
2033 * make.h: Create an UNUSED macro to mark unused parameters.
2034 * (many): Clean up warnings by applying UNUSED, fixing
2035 signed/unsigned incompatibilities, etc.
2037 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2039 * filedef.h: Name the command_state enumeration.
2040 * file.c (set_command_state): Use the enumeration in the function
2043 * configure.in: Explicitly set SET_MAKE to empty, to disable
2044 MAKE=make even when no make already exists. Fix bug #3823.
2046 2004-02-22 Paul D. Smith <psmith@gnu.org>
2048 * maintMakefile: Perl script to clean up all non-CVS files. Use
2049 it on all the subdirectories for the cvs-clean target.
2051 * main.c (decode_switches): Require non-empty strings for all our
2052 string command-line options. Fixes Debian bug # 164165.
2054 * configure.in: Check for stdarg.h and varargs.h.
2055 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2056 for printing messages.
2057 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2062 A number of patches for OS/2 support from Andreas Buening
2063 <andreas.buening@nexgo.de>:
2065 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2066 disable the SIGCHLD handler.
2067 (reap_children) [OS/2]: Remove special handling of job_rfd.
2068 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2069 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2070 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2071 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2072 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2075 2004-02-21 Paul D. Smith <psmith@gnu.org>
2077 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2078 <mail@kristov.de> reports that if process_begin() fails we don't
2079 handle the error condition correctly in all cases.
2080 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2081 to have a newline on the message.
2083 * job.c (construct_command_argv_internal): Add "test" to UNIX
2084 sh_cmds[]. Fixes Savannah bug # 7606.
2086 2004-02-04 Paul D. Smith <psmith@gnu.org>
2088 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2089 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2090 Hartmut Becker <Hartmut.Becker@hp.com>.
2092 2004-01-21 Paul D. Smith <psmith@gnu.org>
2094 * job.c (load_too_high): Implement an algorithm to control the
2095 "thundering herd" problem when using -l to control job creation
2096 via the load average. The system only recomputes the load once a
2097 second but we can start many jobs in a second. To solve this we
2098 keep track of the number of jobs started in the last second and
2099 apply a weight to try to guess what a correct load would be.
2100 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2101 Also fixes bug #4693.
2102 (reap_children): Decrease the job count for this second.
2103 (start_job_command): Increase the job count for this second.
2105 * read.c (conditional_line): Expand the text after ifn?def before
2106 checking to see if it's a single word. Fixes bug #7257.
2108 2004-01-09 Paul D. Smith <psmith@gnu.org>
2110 * file.c (print_file): Recurse to print all targets in
2111 double-colon rules. Fixes bug #4518, reported (with patch) by
2112 Andrew Chatham <chatham@google.com>.
2114 2004-01-07 Paul D. Smith <psmith@gnu.org>
2116 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2117 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2118 AC_FUNC_SETVBUF_REVERSED.
2120 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2121 (MAKE Variable): Fix Savannah bug #4898.
2123 * job.c (construct_command_argv_internal): Add "!" to the list of
2124 shell escape chars. POSIX sh allows it to appear before a
2125 command, to negate the exit code. Fixes bug #6404.
2127 * implicit.c (pattern_search): When matching an implicit rule,
2128 remember which dependencies have the ignore_mtime flag set.
2129 Original fix provided in Savannah patch #2349, by Benoit
2130 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2132 2003-11-22 Paul D. Smith <psmith@gnu.org>
2134 * README.W32.template (Outputs): Clarification on -j with
2135 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2138 2003-11-02 Paul D. Smith <psmith@gnu.org>
2140 * function.c (func_if): Strip all the trailing whitespace from the
2141 condition, then don't expand it. Fixed bug # 5798.
2143 * expand.c (recursively_expand_for_file): If we're expanding a
2144 variable with no file context, then use the variable's context.
2147 2003-10-21 Paul D. Smith <psmith@gnu.org>
2149 * main.c (log_working_directory): Add newlines to printf()s.
2151 * README.cvs: Add a note to ignore warnings during autoreconf.
2153 * maintMakefile (po_repo): Set a new URL for PO file updates.
2154 (get-config/config.guess get-config/config.sub): Get these files
2155 from the Savannah config project instead of ftp.gnu.org.
2157 2003-10-05 Paul Eggert <eggert@twinsun.com>
2159 * main.c (main): Avoid potential subscript error if environ has
2162 2003-08-22 Paul D. Smith <psmith@gnu.org>
2164 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2165 systems which don't yet implement the C89 standard :-/.
2167 2003-07-18 Paul D. Smith <psmith@gnu.org>
2169 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2170 [WINDOWS32]: Initialize hash.
2172 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2174 * dir.c (read_dirstream): Provide a workaround for broken versions of
2175 the MinGW dirent structure.
2177 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2179 * w32/include/dirent.h: Add __MINGW32__ filter.
2181 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2183 * make.h: Add global declaration of *make_host.
2184 * main.c (print_usage): Remove local declaration of *make_host.
2185 (print_version): Display "This program built for ..." after Copyright
2188 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2190 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2191 execution of "makeinfo --html make.texi".
2193 2003-04-30 Paul D. Smith <psmith@gnu.org>
2195 * build.template: Make some changes to maybe allow this script to
2196 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2198 * README.OS2.template: New file for OS/2 support. Original
2199 contributed by Andreas Buening.
2200 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2203 2003-04-19 Paul D. Smith <psmith@gnu.org>
2205 Fix bug #1405: allow a target to match multiple pattern-specific
2208 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2209 variable.c, where they've always belonged.
2210 * rule.h: Move the prototypes and struct pattern_var as well.
2211 * variable.c (initialize_file_variables): Invoke
2212 lookup_pattern_var() in a loop, until no more matches are found.
2213 If a match is found, create a new variable set for the target's
2214 pattern variables. Then merge the contents of each matching
2215 pattern variable set into the target's pattern variable set.
2216 (lookup_pattern_var): Change this function to be usable
2217 in a loop. It takes a starting position: if NULL, start at the
2218 beginning; if non-NULL, start with the pattern variable after that
2219 position, and return the next matching pattern.
2220 (create_pattern_var): Create a unique instance of
2221 pattern-specific variables for every definition in the makefile.
2222 Don't combine the same pattern together. This allows us to
2223 process the variable handling properly even when the same pattern
2224 is used multiple times.
2225 (parse_variable_definition): New function: break out the parsing
2226 of a variable definition line from try_variable_definition.
2227 (try_variable_definition): Call parse_variable_definition to
2229 (print_variable_data_base): Print out pattern-specific variables.
2230 * variable.h (struct variable): Remember when a variable is
2231 conditional. Also remember its flavor.
2232 (struct pattern_var): Instead of keeping a variable set, we just
2233 keep a single variable for each pattern.
2234 * read.c (record_target_var): Each pattern variable contains only a
2235 single variable, not a set, so create it properly.
2236 * doc/make.texi (Pattern-specific): Document the new behavior.
2238 2003-04-17 Paul D. Smith <psmith@gnu.org>
2240 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2241 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2242 file/directory naming rules for VMS so I can't tell whether this
2245 2003-04-09 Paul D. Smith <psmith@gnu.org>
2247 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2248 DOS-style pathnames: backslash separators and drive specifiers.
2250 2003-03-28 Paul D. Smith <psmith@gnu.org>
2252 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2253 the intermediate flag on all targets. Fixes bug #2515.
2255 2003-03-24 Paul D. Smith <psmith@gnu.org>
2257 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2258 Upgrade to autoconf 2.57 and automake 1.7.3.
2260 * job.c: More OS/2 changes from Andreas Buening.
2262 * file.c (print_file): Fix variable initialization.
2265 * remake.c (notice_finished_file):
2267 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2268 some calls (like readdir()) return NULL in valid situations
2269 without resetting errno. Fixes bug #2846.
2271 2003-02-25 Paul D. Smith <psmith@gnu.org>
2273 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2275 * job.c (_is_unixy_shell) [OS/2]: New function.
2276 Set default shell to /bin/sh.
2277 (reap_children): Close the job_rfd pipe here since we don't use a
2279 (set_child_handler_action_flags): define this to empty on OS/2.
2280 (start_job_command): Close the jobserver pipe and use
2281 child_execute_job() instead of fork/exec.
2282 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2283 rather than exec'ing, then reconfigure stdin/stdout.
2284 (exec_command): Rewrite to use spawn instead of exec. Return the
2287 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2288 in DOS. Handle the TEMP environment variable as in DOS. Don't
2289 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2290 use -j in DOS mode. Use child_execute_job() instead of
2293 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2296 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2297 prototypes that return values.
2299 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2301 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2302 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2304 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2307 2003-02-24 Paul D. Smith <psmith@gnu.org>
2309 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2310 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2311 (child_execute_job) [VMS]: Handle error status properly.
2312 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2314 * function.c (func_shell): Use EINTRLOOP() while reading from the
2315 subshell pipe (Fixes bug #2502).
2316 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2318 * main.c (main): Ditto.
2320 2003-01-30 Paul D. Smith <psmith@gnu.org>
2322 * read.c (eval): eval() was not fully reentrant, because the
2323 collapsed buffer was static. Change it to be an automatic
2324 variable so that eval() can be invoked recursively.
2326 (eval): Apply patch # 1022: fix memory reference error on long
2327 target-specific variable lines.
2328 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2330 * function.c (check_numeric): Combine the is_numeric() function
2331 into this function, since it's only called from one place.
2332 Constify this function. Have it print the incorrect string in the
2333 error message. Fixes bug #2407.
2334 (strip_whitespace): Constify.
2335 (func_if): Constify.
2336 * expand.c (expand_argument): Constify.
2338 2003-01-29 Paul D. Smith <psmith@gnu.org>
2340 Fix bug # 2169, also reported by other people on various systems.
2342 * make.h: Some systems, such as Solaris and PTX, do not fully
2343 implement POSIX-compliant SA_RESTART functionality; important
2344 system calls like stat() and readdir() can still fail with EINTR
2345 even if SA_RESTART has been set on the signal handler. So,
2346 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2347 EINTR for system calls which return -1 or 0 (NULL), respectively,
2349 Also, remove the old atomic_stat()/atomic_readdir() and
2350 HAVE_BROKEN_RESTART handling.
2352 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2354 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2355 * remake.c (touch_file): Ditto.
2357 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2358 * read.c (construct_include_path): Ditto.
2359 * remake.c (name_mtime): Ditto.
2360 * vpath.c (selective_vpath_search): Ditto.
2361 * dir.c (find_directory): Ditto.
2362 (local_stat): Ditto.
2363 (find_directory): Use ENULLLOOP() to wrap opendir().
2364 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2366 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2367 atomic_readdir() handling.
2369 2003-01-22 Paul D. Smith <psmith@gnu.org>
2371 * function.c (func_call): Fix Bug #1744. If we're inside a
2372 recursive invocation of $(call ...), mask any of the outer
2373 invocation's arguments that aren't used by this one, so that this
2374 invocation doesn't "inherit" them accidentally.
2376 2002-12-05 Paul D. Smith <psmith@gnu.org>
2378 * function.c (subst_expand): Valery Khamenia reported a
2379 pathological performance hit when doing substitutions on very
2380 large values with lots of words: turns out we were invoking
2381 strlen() a ridiculous number of times. Instead of having each
2382 call to sindex() call strlen() again, keep track of how much of
2383 the text we've seen and pass the length to sindex().
2385 2002-11-19 Paul D. Smith <psmith@gnu.org>
2387 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2390 2002-11-16 Paul D. Smith <psmith@gnu.org>
2392 * NMakefile.template (OBJS): Add hash.c object file.
2393 * SMakefile.template (srcs): Ditto.
2394 * Makefile.ami (objs): Ditto.
2395 * build_w32.bat: Ditto.
2397 * Makefile.DOS.template: Remove extra dependencies.
2399 2002-10-25 Paul D. Smith <psmith@gnu.org>
2401 * expand.c (install_variable_buffer): New function. Install a new
2402 variable_buffer context and return the previous one.
2403 (restore_variable_buffer): New function. Free the current
2404 variable_buffer context and put a previously saved one back.
2405 * variable.h: Prototypes for {install,restore}_variable_buffer.
2406 * function.c (func_eval): Push a new variable_buffer context
2407 before we eval, then restore the old one when we're done.
2410 * read.c (install_conditionals): New function. Install a new
2411 conditional context and return the previous one.
2412 (restore_conditionals): New function. Free the current
2413 conditional context and put a previously saved one back.
2414 (eval): Use the {install,restore}_conditionals for "include"
2416 (eval_buffer): Use {install,restore}_conditionals to preserve the
2417 present conditional state before we evaluate the buffer.
2420 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2422 (Recursion): Add a variable index entry for CURDIR.
2424 * README.cvs: Update to appropriate versions.
2425 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2426 don't need to copy loadavg.c: automake is smart enough to create
2427 it for me. Still have a bug in automake related to ansi2knr tho.
2429 2002-10-14 Paul D. Smith <psmith@gnu.org>
2431 * remake.c (notice_finished_file): Only touch targets if they have
2432 at least one command (as per POSIX). Resolve Bug #1418.
2434 * *.c: Convert to using ANSI C-style function definitions.
2435 * Makefile.am: Enable the ansi2knr feature of automake.
2436 * configure.in: ditto.
2438 2002-10-13 Paul D. Smith <psmith@gnu.org>
2440 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2441 for automatic variable values like $^, etc. In the case of very
2442 large lists of prerequisites this causes problems. Instead reuse
2443 a static buffer (resizeable) for each variable.
2445 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2446 target-specific variable definitions. Check for it and set an
2448 (record_target_var): Set the export field to v_export if the
2449 "exported" flag is set.
2450 * doc/make.texi (Target-specific): Document the ability to use
2453 * doc/make.texi: Change the name of the section on automatic
2454 variables from "Automatic" to "Automatic Variables". Added text
2455 clarifying the scope of automatic variables.
2457 2002-10-04 Paul D. Smith <psmith@gnu.org>
2459 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2461 (record_files): Ditto.
2463 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2464 the search for the '=' to only within the enclosing parens.
2466 2002-10-03 Paul D. Smith <psmith@gnu.org>
2468 Version 3.80 released.
2470 * dir.c: Change hash functions to use K&R function definition style.
2471 * function.c: Ditto.
2473 * variable.c: Ditto.
2475 Update to automake 1.7.
2477 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2478 (pdf): Remove this target as automake now provides one.
2480 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2482 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2484 * makefile.com: Updates for GNU make 3.80.
2485 * makefile.vms: Ditto.
2487 2002-09-23 Paul D. Smith <psmith@gnu.org>
2489 * read.c (enum make_word_type): Remove w_comment.
2490 (get_next_mword): Don't treat comment characters as special; where
2491 this function is used we will never see a comment (it's stripped
2492 before we get here) and treating comments specially means that
2493 targets like "foo\#bar" aren't handled properly.
2495 2002-09-18 Paul D. Smith <psmith@gnu.org>
2497 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2499 * read.c (eval): Expansion of arguments to export/unexport was
2500 ignoring all arguments after the first one. Change the algorithm
2501 to expand the whole line once, then parse the results.
2503 2002-09-17 Paul D. Smith <psmith@gnu.org>
2505 Fix Bug #940 (plus another bug I found while looking at this):
2507 * read.c (record_target_var): enter_file() will add a new entry if
2508 it's a double-colon target: we don't want to do that in this
2509 situation. Invoke lookup_file() and only enter_file() if it does
2510 not already exist. If the file we get back is a double-colon then
2511 add this variable to the "root" double-colon target.
2513 * variable.c (initialize_file_variables): If this file is a
2514 double-colon target but is not the "root" target, then initialize
2515 the root and make the root's variable list the parent of our
2518 2002-09-13 Paul D. Smith <psmith@gnu.org>
2520 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2522 * hash.c (round_up_2): Get rid of a warning.
2524 2002-09-12 Paul D. Smith <psmith@gnu.org>
2526 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2527 so it doesn't complain about getloadavg.c.
2529 * commands.c (set_file_variables): Make sure we always alloca() at
2530 least 1 character for the value of $? (for '\0').
2532 2002-09-11 Paul D. Smith <psmith@gnu.org>
2534 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2535 macro to use RESULT instead of the incorrect _RESULT_.
2537 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2538 and atomic_readdir(). We need to #include dirent.h to get this to
2540 * misc.c (atomic_readdir): Fix typos.
2542 2002-09-10 Paul D. Smith <psmith@gnu.org>
2544 * read.c (eval): Expand variable lists given to export and
2545 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2546 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2548 * doc/make.texi (Variables/Recursion): Document this.
2549 (Conditional Syntax): And here.
2551 2002-09-09 Paul D. Smith <psmith@gnu.org>
2553 * configure.in: Check for memmove().
2555 2002-09-07 Paul D. Smith <psmith@gnu.org>
2557 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2558 Michael Sterrett <msterret@coat.com> reports that while it has
2559 SA_RESTART, it does not work properly.
2561 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2562 that invokes stat() and loops to do it again if it returns EINTR.
2563 (atomic_readdir): Ditto, with readdir().
2565 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2566 and readdir() to atomic_stat() and atomic_readdir().
2568 2002-09-04 Paul D. Smith <psmith@gnu.org>
2570 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2571 reports that GNU make sometimes doesn't recognize that targets can
2572 be made, when directories can be created as prerequisites. He
2573 reports that changing the order of predicates in the DEP->changed
2574 flag test so that lookup_file() is always performed, solves this
2577 2002-08-08 Paul D. Smith <psmith@gnu.org>
2579 * configure.in: Require a newer version of gettext.
2581 * misc.c (perror_with_name): Translate the format string (for
2582 right-to-left language support).
2583 (pfatal_with_name): Ditto.
2585 * main.c: Create a static array of strings to store the usage
2586 text. This is done to facilitate translations.
2587 (struct command_switch): Remove argdesc and description fields.
2588 (switches): Remove values for obsolete fields.
2589 (print_usage): Print each element of the usage array.
2591 * hash.c: Change function definitions to be K&R style.
2593 2002-08-02 Paul D. Smith <psmith@gnu.org>
2595 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2596 this one because it's too hard to get right. We'll look at it for
2598 * main.c (main): Don't create the .TARGETS variable.
2599 * variable.c (handle_special_var): Don't handle .TARGETS.
2601 2002-08-01 Paul D. Smith <psmith@gnu.org>
2603 * main.c (switches): Add a new option, -B (--always-make). If
2604 specified, make will rebuild all targets that it encounters even
2605 if they don't appear to be out of date.
2606 (always_make_flag): New flag.
2607 * make.h: Extern always_make_flag.
2608 * remake.c (update_file_1): Check always_make_flag; if it's set we
2609 will always rebuild any target we can, even if none of its
2610 prerequisites are newer.
2613 * doc/make.texi (Shell Function): Make it clear that make
2614 variables marked as "export" are not passed to instances of the
2617 Add new introspection variable .VARIABLES and .TARGETS.
2619 * variable.c (handle_special_var): New function. If the variable
2620 reference passed in is "special" (.VARIABLES or .TARGETS),
2621 calculate the new value if necessary. .VARIABLES is handled here:
2622 walk through the hash of defined variables and construct a value
2623 which is a list of the names. .TARGETS is handled by
2624 build_target_list().
2625 (lookup_variable): Invoke handle_special_var().
2626 * file.c (build_target_list): Walk through the hask of known files
2627 and construct a list of the names of all the ones marked as
2629 * main.c (main): Initialize them to empty (and as simple variables).
2630 * doc/make.texi (Special Variables): Document them.
2631 * NEWS: Mention them.
2633 * variable.h (struct variable): Add a new flag "exportable" which
2634 is true if the variable name is valid for export.
2635 * variable.c (define_variable_in_set): Set "exportable" when a new
2636 variable is defined.
2637 (target_environment): Use the "exportable" flag instead of
2638 re-checking the name here... an efficiency improvement.
2640 2002-07-31 Paul D. Smith <psmith@gnu.org>
2642 * config.h-vms.template: Updates to build on VMS. Thanks to
2643 Brian_Benning@aksteel.com for helping verify the build.
2644 * makefile.com: Build the new hash.c file.
2645 * hash.h: Use strcpmi(), not stricmp(), in the
2646 HAVE_CASE_INSENSITIVE_FS case.
2648 2002-07-30 Paul D. Smith <psmith@gnu.org>
2650 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2651 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2652 Reported by <Brian_Benning@aksteel.com>.

2656 * variable.c (pop_variable_scope): Remove variable made unused by
2657 new hash infrastructure.
2658 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2659 comparisons as well as name comparisons.
2660 * variable.h: Add a prototype for new hash_init_function_table().
2661 * file.c (lookup_file): Remove variables made unused by new hash
2663 * dir.c (directory_contents_hash_2): Missing return of hash value.
2664 (dir_contents_file_exists_p): Remove variables made unused by new
2665 hash infrastructure.
2668 Installed Greg McGary's integration of the hash functions from the
2669 GNU id-utils package:
2671 2002-07-10 Greg McGary <greg@mcgary.org>
2673 * scripts/functions/filter-out: Add literals to to the
2674 pattern space in order to add complexity, and trigger
2675 use of an internal hash table. Fix documentation strings.
2676 * scripts/targets/INTERMEDIATE: Reverse order of files
2677 passed to expected `rm' command.
2679 2002-07-10 Greg McGary <greg@mcgary.org>

2771 2002-07-10 Paul D. Smith <psmith@gnu.org>
2773 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2774 prerequisite list. A real SysV make will expand the entire
2775 prerequisites list _twice_: we don't do that as it's a big
2776 backward-compatibility problem. We only replace those specific
2779 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2780 references left in the list of prerequisites. Check for .POSIX as
2781 we record targets, so we can disable non-POSIX behavior while
2782 reading makefiles as well as running them.
2783 (eval): Check the prerequisite list to see if we have anything
2784 that looks like a SysV prerequisite variable reference.
2786 2002-07-09 Paul D. Smith <psmith@gnu.org>
2788 * doc/make.texi (Prerequisite Types): Add a new section describing
2789 order-only prerequisites.
2791 * read.c (uniquize_deps): If we have the same file as both a
2792 normal and order-only prereq, get rid of the order-only prereq,
2793 since the normal one supersedes it.
2795 2002-07-08 Paul D. Smith <psmith@gnu.org>
2797 * AUTHORS: Added Greg McGary to the AUTHORS file.
2798 * NEWS: Blurbed order-only prerequisites.
2799 * file.c (print_file): Show order-only deps properly when printing
2802 * maintMakefile: Add "update" targets for wget'ing the latest
2803 versions of various external files. Taken from Makefile.maint in
2806 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2807 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2809 2002-07-07 Paul D. Smith <psmith@gnu.org>
2811 * po/*.po: Remove. We'll use wget to retrieve them at release
2814 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2815 rather than a shell you get an exception. Make sure we look up
2816 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2818 * remake.c (notice_finished_file): Fix handling of -t flag.
2819 Patch provided by Henning Makholm <henning@makholm.net>.
2821 * implicit.c (pattern_search): Some systems apparently run short
2822 of stack space, and using alloca() in this function caused an
2823 overrun. I modified it to use xmalloc() on the two variables
2824 which seemed like they might get large. Fixes Bug #476.
2826 * main.c (print_version): Update copyright notice to conform with
2828 (print_usage): Update help output.
2830 * function.c (func_eval): Create a new make function, $(eval
2831 ...). Expand the arguments, put them into a buffer, then invoke
2832 eval_buffer() on the resulting string.
2833 (func_quote): Create a new function, $(quote VARNAME). Inserts
2834 the value of the variable VARNAME without expanding it any
2837 * read.c (struct ebuffer): Change the linebuffer structure to an
2838 "eval buffer", which can be either a file or a buffer.
2839 (eval_makefile): Move the code in the old read_makefile() which
2840 located a makefile into here: create a struct ebuffer with that
2841 information. Have it invoke the new function eval() with that
2843 (eval_buffer): Create a new function that creates a struct ebuffer
2844 that holds a string buffer instead of a file. Have it invoke
2845 eval() with that ebuffer.
2846 (eval): New function that contains the guts of the old
2847 read_makefile() function: this function parses makefiles. Obtains
2848 data to parse from the provided ebuffer. Some modifications to
2849 make the flow of the function cleaner and clearer. Still could
2850 use some work here...
2851 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2852 contents of the define/endef variable from the ebuffer.
2853 (readstring): Read the next line from a string-style ebuffer.
2854 (readline): Read the next line from an ebuffer. If it's a string
2855 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2858 * dep.h (eval_buffer): Prototype eval_buffer();
2860 * variable.c (do_variable_definition): Make sure that all
2861 non-target-specific variables are registered in the global set.
2862 If we're invoked from an $(eval ...) we might be inside a $(call
2863 ...) or other function which has pushed a variable scope; we still
2864 want to define our variables from evaluated makefile code in the
2867 2002-07-03 Greg McGary <greg@mcgary.org>
2869 * dep.h (struct dep) [ignore_mtime]: New member.
2870 [changed]: convert to a bitfield.
2871 * implicit.c (pattern_search): Zero ignore_mtime.
2872 * main.c (main, handle_non_switch_argument): Likewise.
2873 * rule.c (convert_suffix_rule): Likewise.
2874 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2875 (read_makefile): Parse '|' in prerequisite list.
2876 (uniquize_deps): Consider ignore_mtime when comparing deps.
2877 * remake.c (update_file_1, check_dep): Don't force remake for
2878 dependencies that have d->ignore_mtime.
2879 * commands.c (FILE_LIST_SEPARATOR): New constant.
2880 (set_file_variables): Don't include a
2881 prerequisite in $+, $^ or $? if d->ignore_mtime.
2884 2002-06-18 Paul D. Smith <psmith@gnu.org>
2886 * make.texinfo: Updates for next revision. New date/rev/etc.
2887 Recreate all Info menus. Change license on the manual to the GNU
2888 Free Documentation License. A number of typos.
2889 (Variables Simplify): Don't use "-" before it's defined.
2890 (Automatic Prerequisites): Rewrite the target example to work
2891 properly if the compile fails. Remove incorrect comments about
2892 how "set -e" behaves.
2893 (Text Functions): Move the "word", "wordlist", "words", and
2894 "firstword" functions here, from "File Name Functions".
2895 * make-stds.texi: Update from latest GNU version.
2896 * fdl.texi: (created) Import the latest GNU version.
2898 2002-06-06 Paul D. Smith <psmith@gnu.org>
2900 * variable.c (do_variable_definition): New function: extract the
2901 part of try_variable_definition() that actually sets the value
2902 into a separate function.
2903 (try_variable_definition): Call do_variable_definition() after
2904 parsing the variable definition string.
2905 (define_variable_in_set): Make the name argument const.
2907 * variable.h (enum variable_flavor): Make public.
2908 (do_variable_definition): Create prototype.
2910 * read.c (read_all_makefiles): Create a new built-in variable,
2912 (read_makefile): Add each makefile read in to this variable value.
2914 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2916 * Makefile.DOS.template: Tweak according to changes in the
2917 distribution. Add back the dependencies of *.o files.
2919 * configh.dos.template: Synchronize with config.h.in.
2921 2002-05-09 Paul D. Smith <psmith@gnu.org>
2923 * file.c (file_timestamp_now): Use K&R function declaration.
2925 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2926 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2927 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2928 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2929 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2930 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2931 nlist.n_name is a pointer rather than an array.
2933 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2934 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2935 * configure.in: Use it instead of the old version.
2937 * main.c (main): Prefer setvbuf() to setlinebuf().
2939 2002-05-08 Paul D. Smith <psmith@gnu.org>
2941 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2942 (loadavg_LDADD): Ditto.
2944 2002-04-29 Paul D. Smith <psmith@gnu.org>
2946 * expand.c (recursively_expand_for_file): Rename
2947 recursively_expand() to recursively_expand_for_file() and provide
2948 an extra argument, struct file. If the argument is provided, set
2949 the variable scope to that of the file before expanding.
2950 * variable.h (recursively_expand): Make this a macro that invokes
2951 recursively_expand_for_file() with a NULL file pointer.
2952 * variable.c (target_environment): Call the renamed function and
2953 provide the current file context.
2954 Fixes Debian bug #144306.
2956 2002-04-28 Paul D. Smith <psmith@gnu.org>
2958 Allow $(call ...) user-defined variables to be self-referencing
2959 without throwing an error. Allows implementation of transitive
2960 closures, among other possibly useful things.
2961 Requested by: Philip Guenther <guenther@sendmail.com>
2963 * variable.h (struct variable): Add a new field: exp_count, and
2964 new macros to hold its size and maximum value.
2965 (warn_undefined): Make this a macro.
2966 * variable.c (define_variable_in_set): Initialize it.
2967 * expand.c (recursively_expand): If we detect recursive expansion
2968 of a variable, check the exp_count field. If it's greater than 0
2969 allow the recursion and decrement the count.
2970 (warn_undefined): Remove this (now a macro in variable.h).
2971 * function.c (func_call): Before we expand the user-defined
2972 function, modify its exp_count field to contain the maximum
2973 number of recursive calls we'll allow. After the call, reset it
2976 2002-04-21 Paul D. Smith <psmith@gnu.org>
2978 Modified to use latest autoconf (2.53), automake (1.6.1), and
2979 gettext (0.11.1). We're using gettext's new "external" support,
2980 to avoid including libintl source with GNU make.
2982 * README.cvs: New file. Explain how to build GNU make from CVS.
2984 * configure.in: Modify checking for the system glob library.
2985 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2986 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2987 etc. will manage it correctly). Set an automake conditional
2988 USE_LOCAL_GLOB to decide whether to compile the glob library.
2990 * getloadavg.c (main): Include make.h in the "TEST" program to
2993 * Makefile.am: Remove special rules for loadavg. Replace them
2994 with Automake capabilities for building extra programs.
2996 * signame.c: This file does nothing if the system provide
2997 strsignal(). If not, it implements strsignal(). If the system
2998 doesn't define sys_siglist, then we make our own; otherwise we use
3000 * signame.h: Removed.
3002 * main.c (main): No need to invoke signame_init(). Update copyright.
3004 * ABOUT-NLS: Removed.
3005 * gettext.c: Removed.
3006 * gettext.h: Get a simplified copy from the gettext package.
3008 * i18n/*.po: Moved to po/.
3011 * config/*: Created. Contains package configuration helper files.
3012 * config.guess, config.sub: Moved to config directory.
3014 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3015 Rework to use new-style autoconf features. Use the "external"
3016 mode for gettext. Make the build.sh config file conditional on
3017 whether build.sh.in exists, to avoid autoconf errors.
3018 * acinclude.m4: Removed almost all macros as being obsolete.
3019 Rewrote remaining macros to use AC_DEFINE.
3020 * acconfig.h: Removed.
3022 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3023 conditional to handle customs support. Remove special handling
3026 2002-04-20 Paul D. Smith <psmith@gnu.org>
3028 * function.c (func_call): Don't mark the argument variables $1,
3029 etc. as recursive. They've already been fully expanded so
3030 there's no need to do it again, and doing so strips escaped $'s.
3031 Reported by Sebastian Glita <glseba@yahoo.com>.
3033 * remake.c (notice_finished_file): Walk through double-colon
3034 entries via the prev field, not the next field!
3035 Reported by Greg McGary <greg@mcgary.org>.
3037 * main.c (main): If the user specifies -q and asks for a specific
3038 target which is a makefile, we got an assert. In that case it
3039 turns out we should continue normally instead.
3041 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3043 * i18n/he.po: Installed a new translation.
3045 2002-01-07 Paul D. Smith <psmith@gnu.org>
3047 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3049 2001-12-04 Paul D. Smith <psmith@gnu.org>
3051 * i18n/ja.po: Installed an updated translation.
3053 2001-09-06 Paul Eggert <eggert@twinsun.com>
3055 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3056 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3058 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3060 (main): Get rid of any avoidable limit on stack size.
3062 2001-09-04 Paul D. Smith <psmith@gnu.org>

3066 2001-08-03 Paul D. Smith <psmith@gnu.org>
3068 * i18n/fr.po: Installed an updated translation.
3069 Resolves Debian bug #106720.
3071 2001-06-13 Paul D. Smith <psmith@gnu.org>

3076 2001-06-11 Paul D. Smith <psmith@gnu.org>
3078 * i18n/ko.po: Installed a new translation.
3080 2001-05-06 Paul D. Smith <psmith@gnu.org>
3082 Modify the EINTR handling.
3084 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3085 the way in which we manage the file descriptor/signal handler race
3086 trap to be more efficient.
3088 2001-05-06 Paul Eggert <eggert@twinsun.com>
3090 Restart almost all system calls that are interrupted, instead
3091 of worrying about EINTR. The lone exception is the read() for
3094 * configure.in (HAVE_SA_RESTART): New macro.
3095 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3096 * main.c (main): Use SA_RESTART instead of the old,
3097 nonstandard SA_INTERRUPT.
3099 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3100 * main.c (bsd_signal): New function or macro,
3101 if the implementation doesn't supply it.
3102 (The bsd_signal function will be in POSIX 1003.1-200x.)
3103 (HANDLESIG): Remove.
3104 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3106 * make.h (EINTR_SET): Remove.
3107 (SA_RESTART): New macro.
3109 * arscan.c (ar_member_touch): Don't worry about EINTR.
3110 * function.c (func_shell): Likewise.
3111 * job.c (reap_children, free_child, new_job): Likewise.
3112 * main.c (main): Likewise.
3113 * remake.c (touch_file, name_mtime): Likewise.
3115 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3116 if fstat failed with errno!=EINTR, the error was ignored.
3118 * job.c (set_child_handler_action_flags): New function.
3119 (new_job): Use it to temporarily clear the SIGCHLD action flags
3120 while reading the token.
3122 2001-05-02 Paul D. Smith <psmith@gnu.org>
3124 * job.c (start_job_command): Don't add define/endef per-line flags
3125 to the top-level flags setting.
3127 2001-04-03 Paul D. Smith <psmith@gnu.org>
3129 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3130 bit on error, so check for odd return values, not non-0 return
3132 (VMS_get_member_info): Calculate the timezone differences correctly.
3133 Reported by John Fowler <jfowler@nyx.net>.
3136 2001-03-14 Paul D. Smith <psmith@gnu.org>
3138 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3139 value before invoking define_variable().
3140 Reported by John Fowler <jfowler@nyx.net>.
3142 2001-02-07 Paul D. Smith <psmith@gnu.org>
3144 * read.c (record_target_var): If we reset the variable due to a
3145 command-line variable setting overriding it, turn off the "append"
3148 2001-01-17 Paul D. Smith <psmith@gnu.org>
3150 * variable.c (lookup_variable) [VMS]: When getting values from the
3151 environment, allocate enough space for the _value_ plus escapes,
3152 not enough space for the name plus escapes :-/.
3153 Reported by John Fowler <jfowler@nyx.net>.
3155 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3156 warnings that make generates, so it doesn't look like an error.
3157 Reported by Karl Berry <karl@gnu.org>.
3160 Fix for PR/2020: Rework appended target-specific variables. I'm
3161 fairly confident this algorithm is finally correct.
3163 * expand.c (allocated_variable_append): Rewrite. Instead of
3164 expanding each appended variable then adding all the expanded
3165 strings together, we append all the unexpanded values going up
3166 through the variable set contexts, then expand the final result.
3167 This behaves just like non-target-specific appended variable
3168 values, while the old way didn't in various corner cases.
3169 (variable_append): New function: recursively append the unexpanded
3170 value of a variable, walking from the outermost variable scope to
3172 * variable.c (lookup_variable): Remove the code that looked up the
3173 variable set list if the found variable was "append". We don't
3175 (lookup_variable_in_set): Make this non-static so we can use it
3177 (try_variable_definition): Use lookup_variable_in_set() rather
3178 than faking out current_variable_set_list by hand (cleanup).
3179 * variable.h: Add a prototype for the now non-static
3180 lookup_variable_in_set().
3182 2000-11-17 Paul D. Smith <psmith@gnu.org>
3184 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3185 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3186 before throwing a fit.
3188 2000-11-17 Paul D. Smith <psmith@gnu.org>
3190 * read.c (readline): CRLF calculations had a hole, if you hit the
3191 buffer grow scenario just right. Reworked the algorithm to avoid
3192 the need for len or lastlen at all. Problem description with
3193 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3195 2000-10-24 Paul D. Smith <psmith@gnu.org>
3197 * gettext.c (SWAP): Declare this with the prototype, otherwise
3198 some systems don't work (non-32-bit? Reported for Cray T3E).
3199 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3201 2000-10-05 Paul D. Smith <psmith@gnu.org>
3203 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3204 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3206 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3208 2000-09-22 Paul D. Smith <psmith@gnu.org>
3210 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3211 parts of the real gettext.h here, and we expect to really include
3212 the real gettext.h later. If we keep this #define, it's ignored.
3214 2000-09-21 Paul D. Smith <psmith@gnu.org>
3216 * main.c (log_working_directory): Rework the text to use complete
3217 sentences, to make life simpler for the translators.
3219 2000-08-29 Paul D. Smith <psmith@gnu.org>
3221 * file.c (remove_intermediates): Print a debug message before we
3222 remove intermediate files, so the user (if she uses -d) knows
3225 2000-08-21 Paul D. Smith <psmith@gnu.org>
3227 * variable.c (try_variable_definition): Change how we handle
3228 target-specific append variable defns: instead of just setting the
3229 value, expand it as an append _but_ only within the current
3230 target's context. Otherwise we lose all but the last value if the
3231 variable is appended more than once within the current target
3232 context. Fixes PR/1831.
3234 2000-08-16 Paul D. Smith <psmith@gnu.org>
3236 * function.c (func_shell): Nul-terminate the buffer before
3237 printing an exec error message (just in case it's not!).
3238 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3240 2000-07-25 Paul D. Smith <psmith@gnu.org>
3242 * job.c (construct_command_argv_internal): Add "~" to the list of
3243 sh_chars[] which disallow optimizing out the shell call.
3245 2000-07-23 Paul Eggert <eggert@twinsun.com>
3247 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3248 supersedes --disable-nsec-timestamps.
3249 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3250 * README: Remove --disable-nsec-timestamps.
3252 * filedef.h (struct file.low_resolution_time): New member.
3253 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3254 * remake.c (update_file_1):
3255 Avoid spurious rebuilds due to low resolution time stamps,
3256 generalizing the earlier code that applied only to archive members.
3257 (f_mtime): Archive members always have low resolution time stamps.
3259 * configure.in: Remove --disable-nsec-timestamps, as this has
3260 been superseded by .LOW_RESOLUTION_TIME.
3262 2000-07-23 Paul Eggert <eggert@twinsun.com>
3264 * configure.in (enable_nsec_timestamps): Renamed from
3265 make_cv_nsec_timestamps, since enable/disable options
3266 shouldn't be cached.
3268 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3269 and Paul Eggert <eggert@twinsun.com>
3271 * file.c (file_timestamp_now):
3272 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3273 so that clock_gettime is not linked unless needed.
3275 * filedef.h (FILE_TIMESTAMP_HI_RES):
3276 Remove definition; "configure" now does this.
3278 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3279 to before high resolution file timestamp check,
3280 since that check now uses uintmax_t.
3281 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3282 high resolution file timestamps.
3283 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3284 so that we don't link in clock_gettime unnecessarily.
3286 2000-07-17 Paul D. Smith <psmith@gnu.org>
3288 * i18n/ja.po: New version of the translation file.
3290 2000-07-07 Paul D. Smith <psmith@gnu.org>
3292 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3293 the offset calculation.
3294 (name_mtime): Replace EINTR test with EINTR_SET macro.
3296 2000-07-07 Paul Eggert <eggert@twinsun.com>
3300 * remake.c (update_file_1):
3301 Avoid spurious rebuilds of archive members due to their
3302 timestamp resolution being only one second.
3303 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3304 the clock's resolution being lower than file timestamps'.
3305 When warning about future timestamps, report only the discrepancy,
3306 not the absolute value of the timestamp and the current time.
3308 * file.c (file_timestamp_now): New arg RESOLUTION.
3309 * filedef.h (file_timestamp_now): Likewise.
3310 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3312 2000-07-05 Paul D. Smith <psmith@gnu.org>
3314 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3315 to listp. Fixes PR/1793.
3317 2000-06-26 Paul Eggert <eggert@twinsun.com>
3319 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3321 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3323 * remake.c (f_mtime): Remove unused var memtime.
3325 2000-06-25 Martin Buchholz <martin@xemacs.org>
3327 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3328 Ran spell-check on make.texinfo.
3330 2000-06-23 Paul D. Smith <psmith@gnu.org>
3332 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3333 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3334 * make.h: Define these macros.
3336 * Version 3.79.1 released.
3338 * configure.in: Add a new option, --disable-nsec-timestamps, to
3339 avoid using sub-second timestamps on systems that support it. It
3340 can lead to problems, e.g. if your makefile relies on "cp -p".
3341 * README.template: Document the issue with "cp -p".
3343 * config.guess, config.sub: Updated.
