3 * function.c (windows32_openpipe): Update envp after calling
6 2009-08-02 Paul Smith <psmith@gnu.org>
8 * remake.c (notice_finished_file): Ensure file->cmds is not null
9 before looping through them. Fixes Savannah bug #21824.
11 * doc/make.texi (Wildcard Examples): Clarify when objects is
12 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
13 (Include): Clarify the behavior of -include.
14 Fixes Savannah bug #18963.
16 2009-08-01 Paul Smith <psmith@gnu.org>
18 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
19 etc. come on the command line. Fixes Savannah bug #27093.
21 * expand.c (expand_argument): If the argument is large enough use
22 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
24 * variable.c (do_variable_definition): Avoid using alloca() to
25 hold values, which can be large. Fixes Savannah bug #23960.
27 * job.c (new_job): Use memmove() instead of strcpy() since both
28 pointers are in the same memory block. Fixes Savannah bug #27148.
29 Patch by Petr Machata.
31 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
33 * job.c (construct_command_argv_internal): Add "ulimit" and
34 "unset" to the sh_cmds for Unixy shells.
36 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
39 that set make_cv_sys_gnu_glob, so they are also correctly set
40 when the cache has been populated before.
42 2009-07-04 Eli Zaretskii <eliz@gnu.org>
44 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
45 exist, as realpath(3) does where it's supported.
47 2006-07-04 Eli Zaretskii <eliz@gnu.org>
49 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
50 (abspath): Support systems that define HAVE_DOS_PATHS (have
51 drive letters in their file names). Use IS_PATHSEP instead of a
52 literal '/' comparison. Fixes Savannah bug #26886.
54 2009-06-14 Paul Smith <psmith@gnu.org>
56 * remake.c (update_file_1): Remember the original file we marked
57 as updating, so we can clear that flag again. If we find a target
58 via vpath, FILE might change.
59 (check_dep): Ditto. Fixes Savannah bug #13529.
60 Patch by Reid Madsen <reid.madsen@tek.com>.
62 2009-06-13 Paul Smith <psmith@gnu.org>
64 * doc/make.texi (MAKEFILES Variable): Be explicit that files
65 included by MAKEFILES cannot give default goals.
66 * read.c (eval): If set_default is not set, pass the no-default-goal
67 value when we read included makefiles. Fixes Savannah bug #13401.
69 * ar.c (ar_name): Ensure that targets with empty parens aren't
70 considered archive member references: archive members must have a
71 non-empty "member" string. Fixes Savannah bug #18435.
73 * function.c (string_glob): Rely on multi_glob() to determine
74 whether files exist or not. Remove call to file_exists_p() which
75 is not always correct. Fixes Savannah bug #21231.
76 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
77 then only files that really exist will be returned.
78 * dep.h: Add new argument to multi_glob().
79 * rule.c (install_pattern_rule): Ditto.
80 * read.c (eval): Ditto.
81 * main.c (main): Ditto.
82 * implicit.c (pattern_search): Ditto.
83 * file.c (parse_prereqs): Ditto.
84 * default.c (set_default_suffixes): Ditto.
86 2009-06-09 Paul Smith <psmith@gnu.org>
88 * commands.c (set_file_variables): If always_make_flag is set,
89 always add the prereq to $?. Fixes Savannah bug #17825.
91 * remake.c (update_file_1): When rebuilding deps of FILE, also try
92 to rebuild the deps of all the also_make targets for that file.
93 Fixes Savannah bug #19108.
95 * implicit.c (pattern_search): Undo test for is_target, added by
96 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
97 Rule Search Algorithm". Fixes Savannah bug #17752.
99 * main.c (clean_jobserver): Clear the jobserver_fds options and
100 set job_slots to the default when we clean up.
101 (define_makeflags): Return the new MAKEFLAGS value.
102 (main): Reset MAKEFLAGS in the environment when we re-exec.
103 Fixes Savannah bug #18124.
105 2009-06-08 Paul Smith <psmith@gnu.org>
107 * read.c (eval): Collapse continuations post-semicolon on target-
108 specific variables. Fixes Savannah bug #17521.
110 2009-06-07 Paul Smith <psmith@gnu.org>
112 * job.c (reap_children): For older systems without waitpid() (are
113 there any of these left?) run wait(2) inside EINTRLOOP to handle
114 EINTR errors. Fixes Savannah bug #16401.
116 * (various): Debug message cleanup. Fixes Savannah bug #16469.
118 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
120 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
121 not the end, to catch second expansion $(eval ...) defining new
122 target/prereq relationships during snap_deps.
123 Fixes Savannah bug #24622.
125 * read.c (record_files): The second-expansion "f->updating" hack
126 was not completely correct: if assumed that the target with
127 commands always had prerequisites; if one didn't then the ordering
128 was messed up. Fixed for now to use f->updating to decide whether
129 to preserve the last element in the deps list... but this whole
130 area of constructing and reversing the deps list is too confusing
131 and needs to be reworked. Fixes Savannah bug #21198.
133 2009-06-06 Paul Smith <psmith@gnu.org>
135 * hash.c (hash_insert): Remove useless test for NULL.
136 Fixes Savannah bug #21823.
138 * make.h: Move SET_STACK_SIZE determination to make.h.
139 * main.c (main): New global variable, STACK_LIMIT, holds the
140 original stack limit when make was started.
141 * job.c (start_job_command): Reset the stack limit, if we changed it.
142 Fixes Savannah bug #22010.
144 * remake.c (check_dep): Only set the target's state to not-started
145 if it's not already running. Found this while testing -j10 builds
146 of glibc: various targets were being rebuilt multiple times.
147 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
150 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
151 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
154 2009-06-04 Paul Smith <psmith@gnu.org>
156 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
158 * maintMakefile: Modify access of config and gnulib Savannah
159 modules to use GIT instead of CVS.
161 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
162 Fixes Savannah bug #24655.
164 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
165 this can happen during some invocations of $(eval ...) for example.
166 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
168 2009-06-02 Paul Smith <psmith@gnu.org>
170 * configure.in: Check for fileno()
171 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
172 for the makefile file so invocations of $(shell ...) don't inherit it.
173 Fixes Savannah bug #24277.
175 2009-06-01 Paul Smith <psmith@gnu.org>
177 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
178 expansion was handled incorrectly. Rework the default goal
179 handling to save the variable only. Remove default_goal_file and
181 * read.c (eval): Check default_goal_var, not default_goal_name.
182 * read.c (record_target_var): Don't check default_goal_file here.
184 2009-05-31 Paul Smith <psmith@gnu.org>
186 * main.c (main): Expand the .DEFAULT_GOAL variable before using
187 it, and if the multi_glob() returns nothing (say it expanded to
188 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
190 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
191 $(and ..) to the reference. Fixes Savannah bug #25694.
193 * make.1: Be clear that some recipes will be executed even with -n.
194 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
196 * doc/make.texi (Override Directive): Make more clear how
197 overrides and appends interact.
198 Elucidates part of Savannah bug #26207.
200 * read.c (record_target_var): Don't reset the origin on
201 target-specific variables; try_variable_definition() will handle
202 this correctly. Fixes Savannah bug #26207.
204 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
205 Fixes Savannah bug #25712.
207 * implicit.c (pattern_search): Keep a pointer to the beginning of
208 the filename and save that instead of the constructed pointer.
209 Fixes Savannah bug #26593.
210 Patch by Mark Seaborn <mrs@mythic-beasts.com>
212 2009-05-30 Paul Smith <psmith@gnu.org>
214 * doc/make.texi (Multi-Line): Add a description of the new abilities
215 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
216 "command sequence" vs. "recipe" syntax.
217 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
218 after a define, to create variables with those flavors.
220 2009-05-25 Paul Smith <psmith@gnu.org>
222 Reworked the parser for variable assignments to allow multiple
223 modifiers, and in any order. Also allows variable and
224 prerequisites to be modifier names ('export', 'private', etc.)
226 * NEWS: Add notes about user-visible changes.
228 * read.c (struct vmodifiers): Remember what modifiers were seen.
229 (parse_var_assignment): New function to parse variable assignments.
230 (eval): Call the new function. Handle variable assignments earlier.
232 * variable.c (parse_variable_definition): Only parse; don't create var.
233 (assign_variable_definition): Call parse, then create the var.
235 2009-05-24 Paul Smith <psmith@gnu.org>
237 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
238 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
240 2009-03-14 Eli Zaretskii <eliz@gnu.org>
242 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
243 Fixes Savannah bug #25412.
245 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
246 prototype for xmalloc.
247 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
248 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
249 Loop over an array of extensions, instead of duplicating the same
250 code inline. Use SearchPath followed by CreateFile, instead of
251 the obsolete OpenFile. Fixes Savannah bug #17277.
252 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
253 to `find_file'. Fixes Savannah bug #25662.
255 2009-03-07 Eli Zaretskii <eliz@gnu.org>
257 * function.c (func_shell): Don't close pipedes[1] if it is -1.
258 Fixes Savannah bug #20495.
260 2009-02-28 Ralf Wildenhues <address@hidden>
262 * doc/make.texi (Instead of Execution): Document interaction of
263 -t with phony targets.
265 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
267 Introduce a new keyword "private" which applies to target-specific
268 variables and prevents their values from being inherited.
270 * variable.h (struct variable): Add private_var flag to each variable.
271 Add a flag to specify which list entry switches to the parent target.

291 2008-09-30 Eli Zaretskii <eliz@gnu.org>
293 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of

300 * job.c (construct_command_argv_internal): Avoid extra backslash
301 in batch-mode Unixy shells. Under DB_JOBS, display the contents

306 * README.W32.template: Remove obsolete text about non-support for
307 -jN without Unixy shell. Remove obsolete text about not supplying
308 Visual Studio project files (we do supply them). Modify text to
309 prefer GCC builds to MSC builds.
311 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
313 * doc/make.texi (Empty Targets): Fix typo.
315 2008-03-27 Paul Smith <psmith@gnu.org>
317 Fix Savannah bug #22379:
318 * ar.c (ar_glob_match): Zero the allocated structure.
319 * read.c (parse_file_seq): Ditto.
321 2008-03-08 Brian Dessent <brian@dessent.net>
323 * maintMakefile: Update Translation Project location.
325 2008-01-26 Eli Zaretskii <eliz@gnu.org>
327 * variable.c (target_environment): Don't use shell_var if its
328 `value' field is NULL.
330 2007-12-22 Eli Zaretskii <eliz@gnu.org>
332 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
334 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
335 (TEXINFOS): Value changed to `doc/make.texi'.
336 (.SUFFIXES): Use .texi instead of .texinfo.
337 (make.info, make.dvi): Depend on doc/make.texi.
338 (.texi.info): New target, instead of ".texinfo.info". Change -I
339 switch to $(MAKEINFO) to look in doc/. Use --no-split.
340 (.texi): New target, instead of ".texinfo". Change -I switch to
341 $(MAKEINFO) to look in doc/. Use --no-split.
342 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
343 switch to $(MAKEINFO) to look in doc/.
344 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
345 "*.i[0-9][0-9]" (due to --no-split above).
346 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
347 (html, make_1.html): New targets.
348 (.PHONY): Add "html".
349 (.SUFFIXES): Add .html.
351 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
353 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
354 HAVE_DECL_SYS_SIGLIST.
356 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
357 build does not use child_execute_job.
359 * variable.c (define_automatic_variables) [__MSDOS__]: Always
360 export the SHELL environment variable to the child.
362 2007-12-22 Eli Zaretskii <eliz@gnu.org>
364 * config.h.W32: Include sys/types.h.

371 2007-11-04 Paul Smith <psmith@gnu.org>
373 * doc/make.texi: Convert references to "commands", "command
374 lines", and "command script" to "recipe".
376 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:

381 * remake.c (f_mtime): Print time difference values between 100 and
382 ULONG_MAX in fixed-point notation rather than in exponention notation.
384 2007-10-12 Eli Zaretskii <eliz@gnu.org>
386 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
387 a more complex value than a simple shell: if it's not a default
388 shell now then expand it and see if is a default shell then.
390 2007-10-10 Eli Zaretskii <eliz@gnu.org>
392 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
393 pathnames, with const strings.
394 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
395 from the template (used for building from CVS, not a dist).
397 2007-10-10 Paul Smith <psmith@gnu.org>
399 * make.h: Add a prototype for w32_kill() (change suggested by
400 Yongwei Wu <wuyongwei@gmail.com>).
402 2007-09-21 Eli Zaretskii <eliz@gnu.org>
404 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
407 2007-09-12 Paul Smith <psmith@gnu.org>
409 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
410 Provided by Diego Biurrun <diego@biurrun.de>
411 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
412 Provided by Diego Biurrun <diego@biurrun.de>
414 2007-09-11 Paul Smith <psmith@gnu.org>
416 * doc/make.texi (Special Variables): Moved this into the "How to
417 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
418 (MAKEFILE_LIST) No longer a section; this was added into the
419 "Special Variables" section.
420 (Rule Introduction): Reference .RECIPEPREFIX.
421 (Simple Makefile): Ditto.
422 (Rule Syntax): Ditto.
423 (Command Syntax): Ditto.
424 (Error Messages): Ditto.
426 2007-09-10 Paul Smith <psmith@gnu.org>
428 * commands.c (print_commands): Don't print an extra line in the
429 command scripts. Prefix the command scripts with cmd_prefix, not \t.
431 * read.c (construct_include_path): Add the full string to the cache; we
432 were chopping the last char.
434 * NEWS: Announce the .RECIPEPREFIX special variable.
435 * variable.c (lookup_special_var): Rename from handle_special_var().
436 (lookup_variable): Call the new name.
437 (set_special_var): New function: handle setting of special variables.
438 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
439 (do_variable_definition): Call it.
440 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
441 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
442 * main.c (main): Create the .RECIPEPREFIX special variable.
443 * read.c (eval): Remove the cmd_prefix characters from the command
444 scripts here, so they're not stored in the commands array at all,
445 rather than waiting and stripping them out during command construction.
446 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
448 2007-08-15 Paul Smith <psmith@gnu.org>
450 * doc/make.texi (GNU Free Documentation License): The fdl.texi
451 file has had the section info removed, so add some to make.texi
452 before we include it.
454 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
456 * remake.c (check_dep): Reset the target state for intermediate
457 files. They might have been considered before but not updated
458 then (order-only for example) but they will be this time.
459 Fixes Savannah bug #'s 3330 and 15919.
461 2007-07-21 Eli Zaretskii <eliz@gnu.org>
463 Fix Savannah bug #20549:
464 * function.c (func_shell): Call construct_command_argv with zero
466 * job.c (construct_command_argv_internal): New argument FLAGS; all
468 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
470 * job.h (construct_command_argv_internal): Update prototype.
472 2007-07-13 Paul Smith <psmith@gnu.org>
474 * file.c (expand_deps): Use variable_buffer as the start of the
475 buffer, not the original pointer (in case it was reallocated).
476 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
477 Fixes Savannah bug #20452.
479 2007-07-04 Paul Smith <psmith@gnu.org>
481 * (ALL FILES): Update to GPLv3.
482 * (ALL FILES): Update copyright for 2007.
484 * main.c (print_version): Move the host type info to the second line.
486 2007-06-29 Thiemo Seufer <ths@mips.com>
488 * maintMakefile: Update Translation Project location.
490 2007-06-13 Paul Smith <psmith@gnu.org>
492 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
493 "Expansion of a deferred"
494 Fixes Savannah bug #20018.
496 * expand.c (variable_expand_for_file): Preserve the value of
497 reading_file rather than setting it to 0 at the end.
498 Fixes Savannah bug #20033.
500 2007-05-11 Paul Smith <psmith@gnu.org>
502 * job.c (new_job): Add debug info to specify where make found the
503 command script it is running to build a target.
504 Fixes Savannah bug #18617.
506 * default.c (default_suffixes,default_suffix_rules,default_variables):
507 Add support for Objective C. Fixes Savannah bug #16389.
508 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
510 * function.c (func_lastword): Initialize p.
512 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
513 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
514 Dave Korn <dave.korn@artimi.com>
516 2007-05-08 Paul Smith <psmith@gnu.org>
518 Fix Savannah bug #19656:
520 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
522 * make.h: Change all case-insensitive string compares to use
523 strcasecmp() (from POSIX). If we don't have that but do have one
524 of the others, define strcasecmp to be one of those instead. If
525 we don't have any, declare a prototype for our own version.
527 * misc.c (strcasecmp): Use this if we can't find any native
528 case-insensitive string comparison function.
529 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
530 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
532 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
533 strcasecmp() instead of stricmp().
534 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
535 instead of strcmpi().
536 * acinclude.m4: Remove the strcasecmp() check from here.
538 2007-03-21 Paul Smith <psmith@gnu.org>
540 * configure.in: Don't turn on case-insensitive file system support
541 if --disable-... is given. Fixes Savannah bug #19348.
543 2007-03-19 Paul Smith <psmith@gnu.org>
545 * ALL: Use the strcache for all file name strings, or other
546 strings which we will never free. The goal is to save memory by
547 avoiding duplicate copies of strings. However, at the moment this
548 doesn't save much memory in most situations: due to secondary
549 expansion we actually save prerequisite lists twice (once before
550 the secondary expansion, and then again after it's been parsed
551 into individual file names in the dep list). We will resolve this
552 in a future change, by doing the parsing up-front for targets
553 where secondary expansion is not set.
555 Moving things into the strcache also allows us to use const
556 pointers in many more places.
558 2007-01-03 Paul Smith <psmith@gnu.org>
560 * make.h (ENULLLOOP): Reset errno after each failed invocation of
561 the function, not just the first. Fixes Savannah bug #18680.
563 2006-11-18 Paul Smith <psmith@gnu.org>
565 * strcache.c (strcache_add_len): Don't allocate a new buffer
566 unless the string is not already nil-terminated. Technically this
567 is a violation of the standard, since we may be passed an array
568 that is not long enough to test one past. However, in make this
569 is never true since we only use nil-terminated strings or
572 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
574 * main.c: New global cmd_prefix, defaults to '\t'.
575 * job.c (construct_command_argv_internal): Use cmd_prefix instead
579 (dir_contents_file_exists_p): Check for an error return from
580 readdir(), just in case.

595 backslashes and drive letters as absolute.
597 2006-10-22 Paul Smith <psmith@gnu.org>
599 * main.c (struct command_switch): Use const and void*.
601 2006-10-21 Paul Smith <psmith@gnu.org>
604 * arscan.c: Constified.
606 2006-09-30 Paul Smith <psmith@gnu.org>
608 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
609 point to lastword since the example was updated.
610 Fixes Savannah bug #16304.
611 (Secondary Expansion): Correct example description.
612 Fixes Savannah bug #16468.
613 (Makefile Contents): Clarify that comments cannot appear within
614 variable references or function calls.
615 Fixes Savannah bug #16577.
616 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
617 Fixes Savannah bug #17701.

669 that don't have extended grep.
670 (cvsclean): Use $(PERL) instead of perl.
672 2006-04-09 Paul D. Smith <psmith@gnu.org>

738 Declare and define sh_chars_sh[].
740 2006-03-23 Paul D. Smith <psmith@gnu.org>
742 * configure.in: Look for build.sh.in in $srcdir so it will be
743 built for remote configurations as well.
745 * Makefile.am: Make sure to clean up build.sh during distclean.
746 Fixes Savannah bug #16166.
748 * misc.c (log_access): Takes a const char *.
749 * function.c (fold_newlines): Takes an unsigned int *.
750 Both fixes for Savannah bug #16170.

799 (allocated_variable_append): Don't expand the final result.
800 Fixes Savannah bug #15913.
802 2006-03-09 Paul Smith <psmith@gnu.org>
804 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
805 listed non-existent files as changed. Turns out there's a bug in
806 the Linux kernel builds which means that this change causes
807 everything to rebuild every time. We will re-introduce this fix
808 in the next release, to give them time to fix their build system.
809 Fixes Savannah bug #16002.
810 Introduces Savannah bug #16051.
812 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
813 we *don't* find UNIX "/".

829 * commands.c (set_file_variables): Realloc, not malloc, the static
830 string values to avoid memory leaks.
832 * expand.c (recursively_expand_for_file): Only set reading_file to
833 an initialized value.
835 * implicit.c (pattern_search): We need to make a copy of the stem
836 if we get it from an intermediate dep, since those get freed.
838 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
840 (enter_file) [VMS]: Ditto.

845 * job.c (construct_command_argv_internal): Fix last change.
847 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
848 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
849 the calls to _beginthreadex.
851 * expand.c (recursively_expand_for_file): Initialize `save' to
852 prevent compiler warnings.
854 2006-02-18 Eli Zaretskii <eliz@gnu.org>
856 * job.c (construct_command_argv_internal): Don't create a temporary
857 script/batch file if we are under -n. Call _setmode to switch the
858 script file stream to text mode.

862 * variable.c (merge_variable_set_lists): Don't try to merge the
863 global_setlist. Not only is this useless, but it can lead to
864 circularities in the linked list, if global_setlist->next in one
865 list gets set to point to another list which also ends in

869 2006-02-15 Paul D. Smith <psmith@gnu.org>
871 Fix for Savannah bug #106.
873 * expand.c (expanding_var): Keep track of which variable we're
874 expanding. If no variable is being expanded, it's the same as
876 * make.h (expanding_var): Declare it.
877 * expand.c (recursively_expand_for_file): Set expanding_var to the
878 current variable we're expanding, unless there's no file info in
879 it (could happen if it comes from the command line or a default
880 variable). Restore it before we exit.

893 empty string we still need to free the allocated buffer.
895 * implicit.c (pattern_search): If we allocated a variable set for
896 an impossible file, free it.
897 * variable.c (free_variable_set): New function.
898 * variable.h: Declare it.
900 * read.c (read_all_makefiles): Makefile names are kept in the
901 strcache, so there's never any need to alloc/free them.
904 * main.c (main): Add "archives" to the .FEATURES variable if
905 archive support is enabled.
906 * doc/make.texi (Special Variables): Document it.
908 2006-02-13 Paul D. Smith <psmith@gnu.org>

916 * (ALL FILES): Updated copyright and license notices.
918 2006-02-10 Paul D. Smith <psmith@gnu.org>
920 A new internal capability: the string cache is a read-only cache
921 of strings, with a hash table interface for fast lookup. Nothing
922 in the cache will ever be freed, so there's no need for reference
923 counting, etc. This is the beginning of a full solution for
924 Savannah bug #15182, but for now we only store makefile names here.
926 * strcache.c: New file. Implement a read-only string cache.
927 * make.h: Add prototypes for new functions.
928 * main.c (initialize_global_hash_tables): Initialize the string cache.
929 (print_data_base): Print string cache stats.

935 * dir.c (dir_contents_file_exists_p): Don't opendir if the
936 directory time stamp didn't change, except on FAT filesystems.
937 Suggested by J. David Bryan <jdbryan@acm.org>.

958 * vpath.c (selective_vpath_search): If the file we find has a
959 timestamp from -o or -W, use that instead of the real time.
960 * remake.c (f_mtime): If the mtime is a special token from -o or
961 -W, don't overwrite it with the real mtime.

979 Fixes Savannah bug #15533.
980 * filedef.h (struct file): Add a new LAST pointer.
982 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
983 the comparison. For 64-bits systems the result of the subtraction

1008 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1010 * remake.c (update_goal_chain): Set g->changed instead of
1011 incrementing it, as it is only 8-bit wide, and could overflow if
1012 many commands got started in update_file.
1014 * w32/include/sub_proc.h: Add a prototype for process_used_slots.

1034 the shell is not sh.exe.
1036 * job.c (create_batch_file): Renamed from create_batch_filename;
1037 all callers changed. Don't close the temporary file; return its
1038 file descriptor instead. New arg FD allows to return the file
1040 (construct_command_argv_internal): Use _fdopen instead of fopen to
1041 open the batch file.

1072 * doc/make.texi (Execution): Add a footnote about changes in
1073 handling of backslash-newline sequences. Mention the differences
1074 on MS-DOS and MS-Windows.
1076 * NEWS: More details about building the MinGW port and a pointer
1077 to README.W32. Fix the section name that describes the new
1078 backward-incompatible processing of backslash-newline sequences.
1079 The special processing of SHELL set to "cmd" is only relevant to
1080 MS-Windows, not MS-DOS.
1082 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1084 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1085 to DWORD, to avoid compiler warnings.
1086 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1087 use %ld in format, to avoid compiler warnings.
1089 * doc/make.texi (Special Targets): Fix a typo.
1090 (Appending): Fix cross-reference to Setting.
1091 (Special Variables, Secondary Expansion, File Name Functions)
1092 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1093 periods after a sentence.
1094 (Execution): Add @: after "e.g.".
1095 (Environment): Fix punctuation.
1096 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1097 (Shell Function, Target-specific): Add @: after "vs."
1099 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1101 * read.c (record_target_var): Initialize variable's export field
1102 with v_default instead of leaving it "initialized" by whatever
1103 garbage happened to be on the heap.
1105 2005-12-12 Paul D. Smith <psmith@gnu.org>
1107 * make.1: Fix some display errors and document all existing options.
1108 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1110 2005-12-11 Paul D. Smith <psmith@gnu.org>
1112 * implicit.c (pattern_search): If 2nd expansion is not set for
1113 this implicit rule, replace the pattern with the stem directly,
1114 and don't re-expand the variable list. Along with the other
1115 .SECONDEXPANSION changes below, fixes bug #13781.
1117 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1119 * implicit.c (pattern_search): Mark other files that this rule
1120 builds as targets so that they are not treated as intermediates
1121 by the pattern rule search algorithm. Fixes bug #13022.
1123 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1125 * remake.c (notice_finished_file): Propagate the change of
1126 modification time to all the double-colon entries only if
1127 it is the last one to be updated. Fixes bug #14334.
1129 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1131 * function.c (func_flavor): Implement the flavor function which
1132 returns the flavor of a variable.
1133 * doc/make.texi (Functions for Transforming Text): Document it.
1134 * NEWS: Add it to the list of new functions.
1136 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1138 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1140 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1141 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1143 2005-10-26 Paul Smith <psmith@gnu.org>
1145 * read.c (record_files): Don't set deps flags if there are no deps.
1146 * maintMakefile: We only need to build the templates when we are
1147 creating a distribution, so don't do it for "all".
1149 2005-10-24 Paul D. Smith <psmith@gnu.org>
1151 Make secondary expansion optional: its enabled by declaring the
1152 special target .SECONDEXPANSION.
1154 * NEWS: Update information on second expansion capabilities.
1155 * doc/make.texi (Secondary Expansion): Document the
1156 .SECONDEXPANSION special target and its behavior.
1157 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1158 prerequisite list was found in a static pattern rule.
1159 (free_dep_chain): Declare a prototype.
1160 * file.c (parse_prereqs): New function: break out some complexity
1162 (expand_deps): If we aren't doing second expansion, replace % with
1163 the stem for static pattern rules. Call the new function.
1164 * filedef.h (parse_prereqs): Declare a prototype.
1165 * implicit.c (pattern_search): Initialize the new staticpattern
1167 * main.c (second_expansion): Declare a global variable to remember
1168 if the special target has been seen. Initialize the new
1169 staticpattern field for prerequisites.
1170 * make.h: Extern for second_expansion.
1171 * misc.c (free_dep_chain): New function: frees a struct dep list.
1172 * read.c (read_all_makefiles): Initialize the staticpattern field.
1173 (eval_makefile): Ditto.
1174 (record_files): Check for the .SECONDEXPANSION target and set
1175 second_expansion global if it's found.
1176 Use the new free_dep_chain() instead of doing it by hand.
1177 Set the staticpattern field for prereqs of static pattern targets.
1179 2005-10-16 Paul D. Smith <psmith@gnu.org>
1181 * main.c (main): Set CURDIR to be a file variable instead of a
1182 default, so that values of CURDIR inherited from the environment
1183 won't override the make value.
1185 2005-09-26 Paul D. Smith <psmith@gnu.org>
1187 * job.c (construct_command_argv_internal): If the line is empty
1188 remember to free the temporary argv strings.
1191 2005-09-16 Paul D. Smith <psmith@gnu.org>
1193 * job.c (start_job_command): The noerror flag is a boolean (single
1194 bit); set it appropriately.
1195 Reported by Mark Eichin <eichin@metacarta.com>
1197 2005-08-29 Paul D. Smith <psmith@gnu.org>
1199 * function.c (func_error): On Windows, output from $(info ...)
1200 seems to come in the wrong order. Try to force it with fflush().
1202 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1204 * read.c (record_files): Move code that sets stem for static
1205 pattern rules out of the if (!two_colon) condition so it is
1206 also executed for two-colon rules. Fixes Savannah bug #13881.
1208 2005-08-08 Paul D. Smith <psmith@gnu.org>
1210 * make.h: Don't test that __STDC__ is non-0. Some compilers
1211 (Windows for example) set it to 0 to denote "ISO C + extensions".
1214 2005-08-07 Paul D. Smith <psmith@gnu.org>
1216 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1217 conditional (slightly different version of a fix from Eli).
1219 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1220 If make is running in parallel without -k and two jobs die in a
1221 row, but not too close to each other, then make will quit without
1222 waiting for the rest of the jobs to die.
1224 * main.c (die): Don't reset err before calling reap_children() the
1225 second time: we still want it to be in the error condition.
1226 * job.c (reap_children): Use a static variable, rather than err,
1227 to control whether or not the error message should be printed.
1229 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1231 * w32/subproc/sub_proc.c: Include signal.h.
1232 (process_pipe_io, process_file_io): Pass a pointer to a local
1233 DWORD variable to GetExitCodeProcess. If the exit code is
1234 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1236 * job.c [WINDOWS32]: Include windows.h.
1237 (main_thread) [WINDOWS32]: New global variable.
1238 (reap_children) [WINDOWS32]: Get the handle for the main thread
1239 and store it in main_thread.
1241 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1242 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1243 doing anything else. When we are done, close the main thread
1244 handle and exit with status 130.
1246 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1248 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1251 * main.c (find_and_set_default_shell): If found a DOSish shell,
1252 set sh_found and the value of default_shell, and report the
1253 findings in debug mode.
1255 * job.c (construct_command_argv_internal): Check unixy_shell, not
1256 no_default_sh_exe, to decide whether to use Unixy or DOSish
1259 * README.W32: Update with info about the MinGW build.
1261 * build_w32.bat: Support MinGW.
1263 * w32/subproc/build.bat: Likewise.
1265 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1266 printing DWORD args.
1268 * function.c (windows32_openpipe): Fix format strings for printing
1271 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1273 (start_job_command): Fix format string for printing the result of
1275 (start_job_command) [WINDOWS32]: Do not define.
1276 (exec_command): Fix format string for printing HANDLE args.
1278 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1279 to avoid compiler warnings.
1280 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1281 (Note: some of these fixes were submitted independently by J. Grant)
1283 2005-07-30 J. Grant <jg@jguk.org>
1285 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1286 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1287 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1289 2005-07-15 Paul Smith <psmith@gnu.org>
1291 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1292 we don't have a POSIX shell, then revert to the old
1293 backslash-newline behavior (where they are stripped).
1296 2005-07-08 Paul D. Smith <psmith@gnu.org>
1298 * config.h.W32.template: Reorder to match the standard config.h,
1299 for easier comparisons.
1300 From J. Grant <jg@jguk.org>
1302 * maintMakefile: Remove .dep_segment before overwriting it, in
1303 case it's not writable or noclobber is set.
1304 * expand.c (variable_expand_string): Cast result of pointer
1305 arithmetic to avoid a warning.
1306 * main.c (switches): Add full-fledged final initializer.
1308 2005-07-06 Paul D. Smith <psmith@gnu.org>
1310 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1311 * signame.c (strsignal): If we found _sys_siglist[] or
1312 __sys_siglist[] use those instead of sys_siglist[].
1313 From Albert Chin <china@thewrittenword.com>
1315 2005-07-04 Paul D. Smith <psmith@gnu.org>
1317 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1318 globfree(); set up to use the GNU versions.
1319 From Martin Zinser <zinser@zinser.no-ip.info>
1321 2005-07-03 Paul D. Smith <psmith@gnu.org>
1323 From J. Grant <jg@jguk.org>:
1325 * README.W32.template: Update the Windows and tested MSVC versions.
1326 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1327 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1328 * build_w32.bat: Ditto.
1329 * w32/subproc/build.bat: Ditto.
1331 2005-06-28 Paul D. Smith <psmith@gnu.org>
1333 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1334 declaration was checked but not present.
1336 2005-06-27 Paul D. Smith <psmith@gnu.org>
1338 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1339 to unsigned long. Fixes Savannah bug #13550.
1341 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1342 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1343 Fixes Savannah bug #13551.
1345 2005-06-26 Paul D. Smith <psmith@gnu.org>
1347 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1348 it if ANSI_STRING is not set.
1350 2005-06-25 Paul D. Smith <psmith@gnu.org>
1352 * read.c (eval): If no filenames are passed to any of the
1353 "include" variants, don't print an error.
1354 * doc/make.texi (Include): Document this.
1355 Fixes Savannah bug #1761.
1357 * job.c (construct_command_argv_internal): Sanitize handling of
1358 backslash/newline pairs according to POSIX: that is, keep the
1359 backslash-newline in the command script, but remove a following
1360 TAB character, if present. In the fast path, make sure that the
1361 behavior matches what the shell would do both inside and outside
1362 of quotes. In the slow path, quote the backslash and put a
1363 literal newline in the string.
1364 Fixes Savannah bug #1332.
1365 * doc/make.texi (Execution): Document the new behavior and give
1367 * NEWS: Make a note of the new behavior.
1369 * make.h [WINDOWS32]: #include <direct.h>.
1370 Fixes Savannah bug #13478.
1372 * remake.c (name_mtime): If the stat() of a file fails and the -L
1373 option was given and the file is a symlink, take the best mtime of
1374 the symlink we can get as the mtime of the file and don't fail.
1375 Fixes Savannah bug #13280.
1377 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1378 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1379 inside a variable reference. Make this function static as it's
1381 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1382 parsing an unexpanded line looking for semicolons.
1383 Fixes Savannah bug #1454.
1384 * misc.c (remove_comments): Move this to read.c and make it static
1385 as it's only used there. Call find_char_unquote() with new arg.
1386 * make.h: Remove prototypes for find_char_unquote() and
1387 remove_comments() since they're static now.
1389 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1390 its export flag and obtain its value. When we need to re-exec,
1391 increment the value and add it into the environment.
1392 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1393 * NEWS: Mention MAKE_RESTARTS.
1394 * main.c (always_make_set): New variable. Change the -B option to
1395 set this one instead.
1396 (main): When checking makefiles, only set always_make_flag if
1397 always_make_set is set AND the restarts flag is 0. When building
1398 normal targets, set it IFF always_make_set is set.
1399 (main): Avoid infinite recursion with -W, too: only set what-if
1400 files to NEW before we check makefiles if we've never restarted
1401 before. If we have restarted, set what-if files to NEW _after_ we
1403 Fixes Savannah bug #7566:
1405 2005-06-17 Paul D. Smith <psmith@gnu.org>
1407 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1408 in the prerequisites list.
1410 2005-06-12 Paul D. Smith <psmith@gnu.org>
1412 Fix Savannah bug # 1328.
1414 * configure.in: Check for atexit().
1415 * misc.c (close_stdout): Test stdout to see if writes to it have
1416 failed. If so, be sure to exit with a non-0 error code. Based on
1417 code found in gnulib.
1418 * make.h: Prototype.
1419 * main.c (main): Install close_stdout() with atexit().
1421 2005-06-10 Paul D. Smith <psmith@gnu.org>
1423 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1425 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1426 headers; make vmsWaitForChildren() static; extern vmsify().
1427 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1428 Don't create child_execute_job() here (it's in vmsjobs.c).
1429 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1431 2005-06-09 Paul D. Smith <psmith@gnu.org>
1433 * variable.c (push_new_variable_scope): File variables point
1434 directly to the global_setlist variable. So, inserting a new
1435 scope in front of that has no effect on those variables: they
1436 don't go through current_variable_set_list. If we're pushing a
1437 scope and the current scope is global, push it "the other way" so
1438 that the new setlist is in the global_setlist variable, and
1439 next points to a new setlist with the global variable set.
1440 (pop_variable_scope): Properly undo a push with the new
1442 Fixes Savannah bug #11913.
1444 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1446 * job.c (reap_children): Don't die of the command failed but
1447 the dontcare flag is set. Fixes Savannah bug #13216.
1449 * implicit.c (pattern_search): When creating a target from
1450 an implicit rule match, lookup pattern target and set precious
1451 flag in a newly created target. Fixes Savannah bug #13218.
1453 2005-05-13 Paul D. Smith <psmith@gnu.org>
1455 Implement "if... else if... endif" syntax.
1457 * read.c (eval): Push all checks for conditional words ("ifeq",
1458 "else", etc.) down into the conditional_line() function.
1459 (conditional_line): Rework to allow "else if..." clause. New
1460 return value -2 for lines which are not conditionals. The
1461 ignoring flag can now also be 2, which means "already parsed a
1462 true branch". If that value is seen no other branch of this
1463 conditional can be considered true. In the else parsing if there
1464 is extra text after the else, invoke conditional_line()
1465 recursively to see if it's another conditional. If not, it's an
1466 error. If so, raise the conditional value to this level instead
1467 of creating a new conditional nesting level. Special check for
1468 "else" and "endif", which aren't allowed on the "else" line.
1469 * doc/make.texi (Conditional Syntax): Document the new syntax.
1471 2005-05-09 Paul D. Smith <psmith@gnu.org>
1473 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1474 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1475 recurses to the w32 directory, even on non-Windows systems. Use
1476 the method suggested in the automake manual.
1477 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1478 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1480 2005-05-07 Paul D. Smith <psmith@gnu.org>
1482 * main.c (die): If we're dying with a fatal error (not that a
1483 command has failed), write back any leftover tokens before we go.
1485 * job.c (set_child_handler_action_flags): If there are jobs
1486 waiting for the load to go down, set an alarm to go off in 1
1487 second. This allows us to wake up from a potentially long-lasting
1488 read() and start a new job if the load has gone down. Turn it off
1490 (job_noop): Dummy signal handler function.
1491 (new_job): Invoke it with the new semantics.
1493 * docs/make.texi: Document secondary expansion. Various cleanups
1496 2005-05-03 Paul D. Smith <psmith@gnu.org>
1498 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1499 the targets which are to ultimately be made are called "goals";
1500 see the GNU make manual. Also, MAKECMDGOALS, etc.
1502 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1503 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1504 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1506 2005-05-02 Paul D. Smith <psmith@gnu.org>
1508 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1509 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1510 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1511 functions to vmsjobs.c. #include it into jobs.c.
1513 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1514 jobserver tokens. I found that this happens when an exported
1515 recursive variable contains a $(shell ...) function reference: in
1516 this situation we could "forget" to write back a token.
1518 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1519 we have. It's not reliable to depend on the number of children in
1520 our linked list so keep a separate count.
1521 (new_job): Check jobserver_tokens rather than children &&
1522 waiting_jobs. Increment jobserver_tokens when we get one.
1523 (free_child): If jobserver_tokens is 0, internal error. If it's
1524 >1, write a token back to the jobserver pipe (we don't write a
1525 token for the "free" job). Decrement jobserver_tokens.
1527 * main.c: Add variable master_job_slots.
1528 (main): Set it to hold the number of jobs requested if we're the
1529 master process, when using the jobserver.
1530 (die): Sanity checks: first test jobserver_tokens to make sure
1531 this process isn't holding any tokens we didn't write back.
1532 Second, if master_job_slots is set count the tokens left in the
1533 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1535 2005-04-24 Paul D. Smith <psmith@gnu.org>
1537 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1538 with -l# can lose jobserver tokens, because waiting jobs are not
1539 consulted properly when checking for the "free" token.
1541 * job.c (free_child): Count waiting_jobs as having tokens.
1542 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1543 handle jobs waiting for the load to drop.
1545 2005-04-23 Paul D. Smith <psmith@gnu.org>
1547 * main.c (main): Be careful to not core if a variable setting in
1548 the environment doesn't contain an '='. This is illegal but can
1549 happen in broken setups.
1550 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1552 2005-04-12 Paul D. Smith <psmith@gnu.org>
1554 The second expansion feature causes significant slowdown. Timing
1555 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1556 read the makefile before the feature, to 11+s to do the same
1557 operations after the feature. Additionally, memory usage
1558 increased drastically. To fix this I added some intelligence that
1559 avoids the overhead of the second expansion unless it's required.
1561 * dep.h: Add a new boolean field, need_2nd_expansion.
1563 * read.c (eval): When creating the struct dep for the target,
1564 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1565 (record_files): If there's a "%" in a static pattern rule, it gets
1566 converted to "$*" so set need_2nd_expansion to 1.
1568 * file.c (expand_deps): Rework to be more efficient. Only perform
1569 initialize_file_variables(), set_file_variables(), and
1570 variable_expand_for_file() if the need_2nd_expansion is set.
1572 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1573 (pattern_search): Ditto.
1574 * main.c (handle_non_switch_argument): Ditto.
1576 * read.c (read_all_makefiles): Ditto.
1577 (eval_makefile): Ditto.
1579 2005-04-07 Paul D. Smith <psmith@gnu.org>
1581 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1582 * variable.c (sync_Path_environment): Ditto.
1583 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1585 * main.c (main): Define the .FEATURES variable.
1586 * NEWS: Announce .FEATURES.
1587 * doc/make.texi (Special Variables): Document .FEATURES.
1589 * remake.c (check_dep): If a file is .PHONY, update it even if
1590 it's marked intermediate. Fixes Savannah bug #12331.
1592 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1594 * file.c (expand_deps): Factor out the second expansion and
1595 prerequisite line parsing logic from snap_deps().
1597 * file.c (snap_deps): Use expand_deps(). Expand and parse
1598 prerequisites of the .SUFFIXES special target first. Fixes
1599 Savannah bug #12320.
1601 2005-03-13 Paul D. Smith <psmith@gnu.org>
1603 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1606 2005-03-11 Paul D. Smith <psmith@gnu.org>
1608 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1609 available, not undefined (from Earnie Boyd).
1611 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1613 * implicit.c (pattern_search): Mark an intermediate target as
1614 precious if it happened to be a prerequisite of some (other)
1615 target. Fixes Savannah bug #12267.
1617 2005-03-09 Paul D. Smith <psmith@gnu.org>
1619 * read.c (eval_makefile): Add alloca(0).
1620 (eval_buffer): Ditto.
1622 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1624 * main.c (main): Use o_file instead of o_default when defining
1625 the .DEFAULT_TARGET special variable.
1626 * read.c (eval): Use define_variable_global() instead of
1627 define_variable() when setting new value for the .DEFAULT_TARGET
1628 special variable. Fixes Savannah bug #12266.
1630 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1632 * imlicit.c (pattern_search): Mark files for which an implicit
1633 rule has been found as targets. Fixes Savannah bug #12202.
1635 2005-03-04 Paul D. Smith <psmith@gnu.org>
1638 * doc/make.texi (Automatic Variables): Document $|.
1640 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1642 * read.c (record_files): Instead of substituting % with
1643 actual stem value in dependency list replace it with $*.
1644 This fixes stem triple expansion bug.
1646 * implicit.c (pattern_search): Copy stem to a separate
1647 buffer and make it a properly terminated string. Assign
1648 this buffer instead of STEM (which is not terminated) to
1649 f->stem. Instead of substituting % with actual stem value
1650 in dependency list replace it with $*. This fixes stem
1651 triple expansion bug.
1653 2005-03-01 Paul D. Smith <psmith@gnu.org>
1655 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1656 on Windows, as it takes a handle not a pid. Just exit.
1657 Fix from patch #3679, provided by Alessandro Vesely.
1659 * configure.in: Update check for sys_siglist[] from autoconf manual.
1660 * signame.c (strsignal): Update to use the new autoconf macro.
1662 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1664 * read.c (record_files): Add a check for the list of prerequisites
1665 of a static pattern rule being empty. Fixes Savannah bug #12180.
1667 2005-02-28 Paul D. Smith <psmith@gnu.org>
1669 * doc/make.texi (Text Functions): Update docs to allow the end
1670 ordinal for $(wordlist ...) to be 0.
1671 * function.c (func_wordlist): Fail if the start ordinal for
1672 $(wordlist ...) is <1. Matches documentation.
1673 Resolves Savannah support request #103195.
1675 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1676 previously we were stopping when !-q, exactly the opposite. This
1677 has been wrong since version 1.34, in 1994!
1678 (update_file): If we got an error don't break out to run more
1679 double-colon rules: just return immediately.
1680 Fixes Savannah bug #7144.
1682 2005-02-27 Paul D. Smith <psmith@gnu.org>
1684 * misc.c (end_of_token): Make argument const.
1685 * make.h: Update prototype.
1687 * function.c (abspath, func_realpath, func_abspath): Use
1688 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1689 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1690 * read.c (record_files): Ditto.
1691 * variable.c (do_variable_definition): Ditto.
1693 * function.c (func_error): Create a new function $(info ...) that
1694 simply prints the message to stdout with no extras.
1695 (function_table_init): Add new function to the table.
1696 * NEWS: Add $(info ...) reference.
1697 * doc/make.texi (Make Control Functions): Document it.
1699 New feature: if the system supports symbolic links, and the user
1700 provides the -L/--check-symlink-time flag, then use the latest
1701 mtime between the symlink(s) and the target file.
1703 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1704 readlink(). If both are available, define MAKE_SYMLINKS.
1705 * main.c: New variable: check_symlink_flag.
1706 (usage): Add a line for -L/--check-symlink-times to the help string.
1707 (switches): Add -L/--check-symlink-times command line argument.
1708 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1709 print a warning and disable it again.
1710 * make.h: Declare check_symlink_flag.
1711 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1712 if the file is a symlink then check each link in the chain and
1713 choose the NEWEST mtime we find as the mtime for the file. The
1714 newest mtime might be the file itself!
1715 * NEWS: Add information about this new feature.
1716 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1718 Avoid core dumps described in Savannah bug # 12124:
1720 * file.c: New variable snapped_deps remember whether we've run
1722 (snap_deps): Set it.
1723 * filedef.h: Extern it.
1724 * read.c (record_files): Check snapped_deps; if it's set then
1725 we're trying to eval a new target/prerequisite relationship from
1726 within a command script, which we don't support. Fatal.
1728 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1730 Implementation of the .DEFAULT_TARGET special variable.
1732 * read.c (eval): If necessary, update default_target_name when
1734 * read.c (record_files): Update default_target_file if
1735 default_target_name has changed.
1736 * main.c (default_target_name): Define.
1737 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1738 default_target_name is set use default_target_file as a root
1740 * filedef.h (default_target_name): Declare.
1741 * dep.h (free_dep_chain):
1742 * misc.c (free_dep_chain): Change to operate on struct nameseq
1743 and change name to free_ns_chain.
1744 * file.c (snap_deps): Update to use free_ns_chain.
1746 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1748 Implementation of the second expansion in explicit rules,
1749 static pattern rules and implicit rules.
1751 * read.c (eval): Refrain from chopping up rule's dependencies.
1752 Store them in a struct dep as a single dependency line. Remove
1753 the code that implements SySV-style automatic variables.
1755 * read.c (record_files): Adjust the code that handles static
1756 pattern rules to expand all percents instead of only the first
1757 one. Reverse the order in which dependencies are stored so that
1758 when the second expansion reverses them again they appear in
1759 the makefile order (with some exceptions, see comments in
1760 the code). Remove the code that implements SySV-style automatic
1763 * file.c (snap_deps): Implement the second expansion and chopping
1764 of dependency lines for explicit rules.
1766 * implicit.c (struct idep): Define an auxiliary data type to hold
1767 implicit rule's dependencies after stem substitution and
1770 * implicit.c (free_idep_chain): Implement.
1772 * implicit.c (get_next_word): Implement helper function for
1773 parsing implicit rule's dependency lines into words taking
1774 into account variable expansion requests. Used in the stem
1777 * implicit.c (pattern_search): Implement the second expansion
1778 for implicit rules. Also fixes bug #12091.
1780 * commands.h (set_file_variables): Declare.
1781 * commands.c (set_file_variables): Remove static specifier.
1783 * dep.h (free_dep_chain): Declare.
1784 * misc.c (free_dep_chain): Implement.
1786 * variable.h (variable_expand_for_file): Declare.
1787 * expand.c (variable_expand_for_file): Remove static specifier.
1789 * make.h (strip_whitespace): Declare.
1790 * function.c (strip_whitespace): Remove static specifier.
1792 2005-02-26 Paul D. Smith <psmith@gnu.org>
1794 * main.c (main): Check for ferror() when reading makefiles from stdin.
1795 Apparently some shells in Windows don't close pipes properly and
1798 2005-02-24 Jonathan Grant <jg@jguk.org>
1800 * configure.in: Add MinGW configuration options, and extra w32 code
1802 * Makefile.am: Add MinGW configuration options, and extra w32 code
1804 * main.c: Determine correct program string (after last \ without .exe).
1805 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1807 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1808 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1809 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1810 environment support.
1812 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1814 * function.c (func_shell): When initializing error_prefix, check
1815 that reading file name is not null. This fixes long-standing
1816 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1818 2005-02-09 Paul D. Smith <psmith@gnu.org>
1820 * maintMakefile: Update the CVS download URL to simplify them.
1821 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1822 downloading the .texi files from Savannah now.
1824 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1826 * main.c (handle_non_switch_argument): Only add variables to
1827 command_variables if they're not already there: duplicate settings
1828 waste space and can be confusing to read.
1830 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1831 this header is never included by non-WINDOWS32 code, and it
1832 requires <config.h> to define which isn't always included first.
1834 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1835 testing MINGW32 versions.
1837 * main.c (log_working_directory): flush stdout to be sure the WD
1838 change is printed before any stderr messages show up.
1840 2005-02-01 Paul D. Smith <psmith@gnu.org>
1842 * maintMakefile (po_repo): Update the GNU translation site URL.
1844 2004-12-01 Paul D. Smith <psmith@gnu.org>
1846 * main.c (main): Change char* env_shell to struct variable shell_var.
1847 * variable.c (target_environment): Use new shell_var.
1849 2004-11-30 Paul D. Smith <psmith@gnu.org>
1851 * configure.in: The old way we avoided creating build.sh from
1852 build.sh.in before build.sh.in exists doesn't work anymore; we
1853 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1854 the help!). This also keeps automake from complaining.
1855 * Makefile.am (README): Add a dummy target so automake won't
1856 complain that this file doesn't exist when we checkout from CVS.
1857 * maintMakefile (.dep_segment): Rewrite this rule since newer
1858 versions of automake don't provide DEP_FILES.
1860 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1862 Implementation of `realpath' and `abspath' built-in functions.
1864 * configure.in: Check for realpath.
1865 * function.c (abspath): Return an absolute file name that does
1866 not contain any `.' or `..' components, nor repeated `/'.
1867 * function.c (func_abspath): For each name call abspath.
1868 * function.c (func_realpath): For each name call realpath
1869 from libc or delegate to abspath if realpath is not available.
1870 * doc/make.texi (Functions for File Names): Document new functions.
1871 * doc/make.texi (Quick Reference): Ditto.
1873 2004-11-28 Paul D. Smith <psmith@gnu.org>
1875 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1876 arguments. Fixes bug #10252.
1878 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1880 * main.c (main): Set SHELL to v_noexport by default. Remember the
1881 original environment setting of SHELL in the env_shell variable.
1882 * main.h: Export new env_shell variable.
1883 * variable.c (target_environment): If we find a v_noexport
1884 variable for SHELL, add a SHELL variable with the env_shell value.
1885 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1886 * doc/make.texi (Variables/Recursion): Ditto.
1888 2004-11-28 Paul D. Smith <psmith@gnu.org>
1890 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1891 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1892 Patch by Alessandro Vesely.
1894 2004-11-12 Paul D. Smith <psmith@gnu.org>
1896 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1897 the command line if it's inside a string.
1898 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1900 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1902 * function.c (func_lastword): New function: return last word
1903 from the list of words.
1904 * doc/make.texi: Document $(lastword ). Fix broken links in
1905 Quick Reference section.
1907 2004-10-06 Paul D. Smith <psmith@gnu.org>
1909 Apply patch from Alessandro Vesely, provided with bug # 9748.
1910 Fix use of tmpnam() to work with Borland C.
1912 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1913 construction of a temporary filename, and call new function
1914 create_batch_filename().
1915 (create_batch_filename) [WINDOWS32]: New function to create a
1918 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1920 * read.c (record_target_var): Expand simple pattern-specific
1922 * variable.c (initialize_file_variables): Do not expand simple
1923 pattern-specific variable.
1925 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1927 * remake.c (update_file_1): When rebuilding makefiles inherit
1928 dontcare flag from a target that triggered update.
1930 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1932 * variable.c (initialize_file_variables): Mark pattern-specific
1933 variable as a per-target and copy export status.
1935 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1937 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1939 * implicit.c (pattern_search): When considering an implicit rule's
1940 prerequisite check that it is actually a target rather then
1941 just an entry in the file hashtable.
1943 2004-09-21 Paul D. Smith <psmith@gnu.org>
1945 * read.c (readstring): Fix some logic errors in backslash handling.
1946 (eval): Remove some unnecessary processing in buffer handling.
1947 (record_target_var): Assert that parse_variable_definition() succeeded.
1948 Reported by: Markus Mauhart <qwe123@chello.at>.
1950 * misc.c: Removed the sindex() function. All instances of this
1951 function were trivially replaceable by the standard strstr()
1952 function, and that function will always have better (or certainly
1953 no worse) performance than the very simple-minded algorithm
1954 sindex() used. This can matter with complex makefiles.
1955 * make.h: Remove the prototype for sindex().
1956 * function.c (subst_expand): Convert sindex() call to strstr().
1957 This means we no longer need to track the TLEN value so remove that.
1958 (func_findstring): Convert sindex() to strstr().
1959 * commands.c (chop_commands): Convert sindex() calls to strstr().
1960 Suggested by: Markus Mauhart <qwe123@chello.at>.
1962 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1963 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1964 If SHELL is set to CMD.EXE then assume it's batch-mode and
1965 non-unixy. I wrote the code differently from the patch, though,
1966 to make it safer. This also resolves bug #9174.
1968 2004-09-20 Paul D. Smith <psmith@gnu.org>
1970 * expand.c (variable_expand_string): Modify to invoke
1971 patsubst_expand() instead of subst_expand(); the latter didn't
1972 handle suffix patterns correctly.
1973 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1974 was used only from variable_expand_string() and is no longer used
1976 (func_subst): Ditto, on call to subst_expand().
1977 (patsubst_expand): Require the percent pointers to point to the
1978 character after the %, not to the % itself.
1979 * read.c (record_files): New call criteria for patsubst_expand().
1980 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1981 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1983 2004-09-19 Paul D. Smith <psmith@gnu.org>
1985 * function.c (subst_expand): Fix a check in by_word: look for a
1986 previous blank if we're beyond the beginning of the string, not
1987 the beginning of the word.
1988 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1990 2004-05-16 Paul D. Smith <psmith@gnu.org>
1992 * remake.c (update_goal_chain): Change the argument specifying
1993 whether we're rebuilding makefiles to be a global variable,
1994 REBUILDING_MAKEFILES.
1995 (complain): Extract the code that complains about no rules to make
1996 a target into a separate function.
1997 (update_file_1): If we tried to rebuild a file during the makefile
1998 rebuild phase and it was dontcare, then no message was printed.
1999 If we then try to build the same file during the normal build,
2000 print a message this time.
2001 (remake_file): Don't complain about un-remake-able files when
2002 we're rebuilding makefiles.
2004 2004-05-11 Paul D. Smith <psmith@gnu.org>
2006 * job.c (construct_command_argv_internal): OS/2 patches from
2007 Andreas Buening <andreas.buening@nexgo.de>.
2009 2004-05-10 Paul D. Smith <psmith@gnu.org>
2011 * remake.c (update_file): Don't walk the double-colon chain unless
2012 this is a double-colon rule. Fix suggested by Boris Kolpackov
2013 <boris@kolpackov.net>.
2015 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2016 * readme.vms: New section describing OpenVMS support and issues.
2017 * default.c (default_variables): Add support for IA64.
2018 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2019 without some privilege aborts make with the error
2020 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2021 pressing Ctrl+Y and the input device is no terminal. The change
2022 catches this error and just continues.
2024 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2026 2004-04-25 Paul D. Smith <psmith@gnu.org>
2028 * commands.c (set_file_variables): Set $< properly in the face of
2029 order-only prerequisites.
2030 Patch from Boris Kolpackov <boris@kolpackov.net>
2032 2004-04-21 Bob Byrnes <byrnes@curl.com>
2034 * main.c (main): Notice failures to remake makefiles.
2036 2004-03-28 Paul D. Smith <psmith@gnu.org>
2038 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2040 * job.c: No default shell for RISC OS.
2041 (load_too_high): Hard-code the return to 1.
2042 (construct_command_argv_internal): No sh_chars or sh_cmds.
2043 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2045 2004-03-20 Paul D. Smith <psmith@gnu.org>
2047 * variable.c (do_variable_definition): Don't append from the
2048 global set if a previous non-appending target-specific variable
2049 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2052 * expand.c (reference_variable): Don't give up on variables with
2053 no value that have the target-specific append flag set: they might
2054 have a value after all. Reported by Oliver Schmidt
2055 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2056 <nikulin@dx1cmd.inp.nsk.su>.
2058 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2059 refer to absolute pathnames in directories that don't exist: some
2060 portion of the makefile could create those directories before we
2061 match the pattern. Fixes bugs #775 and #108.
2063 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2065 * main.c (main): Free makefile_mtimes if we have any.
2066 * README.W32.template: Update documentation for the current status
2067 of the MS-Windows port.
2068 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2069 environment variable is sometimes already defined which causes the
2071 * main.c (debug_signal_handler): Only define this function if
2072 SIGUSR1 is available.
2074 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2076 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2077 * README.OS2.template: Documentation updates.
2078 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2079 link line for safety.
2080 * maintMakefile (build.sh.in): Remove an extraneous ")".
2081 * job.c (child_execute_job): Close saved FDs.
2082 * job.c (exec_command) [OS/2]: exec_command(): If the command
2083 can't be exec'ed and if the shell is not Unix-sh, then try again
2084 with argv = { "cmd", "/c", ... }. Normally, this code is never
2085 reached for the cmd shell unless the command really doesn't exist.
2086 (construct_command_argv_internal) [OS/2]: The code for cmd
2087 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2088 The CMD builtin commands are case insensitive so use strcasecmp().
2090 2004-03-19 Paul D. Smith <psmith@gnu.org>
2092 * read.c (do_define): Re-order line counter increment so the count
2093 is accurate (we were losing one line per define). Reported by
2094 Dave Yost <Dave@Yost.com>.
2096 2004-03-06 Paul D. Smith <psmith@gnu.org>
2098 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2100 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2101 * misc.c (message,error,fatal): Ditto.
2102 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2103 * config.h.W32.template: Ditto.
2104 * config.h-vms.template: Ditto.
2105 * config.ami.template: Ditto.
2107 2004-03-04 Paul D. Smith <psmith@gnu.org>
2109 * README.template: Add a note about broken /bin/sh on SunOS
2110 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2112 * misc.c (message, error, fatal): Don't use "..." if we're using
2113 varargs. ansi2knr should handle this but it doesn't work: it
2114 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2115 done. On many systems (SunOS for example) va_dcl is a #define.
2116 So, force the use of the non-"..." version on pre-ANSI compilers.
2118 * maintMakefile (sign-dist): Create some rules to help automate
2119 the new GNU ftp upload method.
2121 2004-02-24 Paul D. Smith <psmith@gnu.org>
2123 * config.h.W32.template: Add HAVE_STDARG_H
2124 * config.h-vms.template: Ditto.
2125 * config.ami.template: Ditto.
2127 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2129 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2130 * build_w32.bat: Remove extra "+".
2132 2004-02-23 Paul D. Smith <psmith@gnu.org>
2134 * make.h: Create an UNUSED macro to mark unused parameters.
2135 * (many): Clean up warnings by applying UNUSED, fixing
2136 signed/unsigned incompatibilities, etc.
2138 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2140 * filedef.h: Name the command_state enumeration.
2141 * file.c (set_command_state): Use the enumeration in the function
2144 * configure.in: Explicitly set SET_MAKE to empty, to disable
2145 MAKE=make even when no make already exists. Fix bug #3823.
2147 2004-02-22 Paul D. Smith <psmith@gnu.org>
2149 * maintMakefile: Perl script to clean up all non-CVS files. Use
2150 it on all the subdirectories for the cvs-clean target.
2152 * main.c (decode_switches): Require non-empty strings for all our
2153 string command-line options. Fixes Debian bug # 164165.
2155 * configure.in: Check for stdarg.h and varargs.h.
2156 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2157 for printing messages.
2158 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2163 A number of patches for OS/2 support from Andreas Buening
2164 <andreas.buening@nexgo.de>:
2166 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2167 disable the SIGCHLD handler.
2168 (reap_children) [OS/2]: Remove special handling of job_rfd.
2169 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2170 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2171 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2172 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2173 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2176 2004-02-21 Paul D. Smith <psmith@gnu.org>
2178 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2179 <mail@kristov.de> reports that if process_begin() fails we don't
2180 handle the error condition correctly in all cases.
2181 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2182 to have a newline on the message.
2184 * job.c (construct_command_argv_internal): Add "test" to UNIX
2185 sh_cmds[]. Fixes Savannah bug # 7606.
2187 2004-02-04 Paul D. Smith <psmith@gnu.org>
2189 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2190 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2191 Hartmut Becker <Hartmut.Becker@hp.com>.
2193 2004-01-21 Paul D. Smith <psmith@gnu.org>
2195 * job.c (load_too_high): Implement an algorithm to control the
2196 "thundering herd" problem when using -l to control job creation
2197 via the load average. The system only recomputes the load once a
2198 second but we can start many jobs in a second. To solve this we
2199 keep track of the number of jobs started in the last second and
2200 apply a weight to try to guess what a correct load would be.
2201 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2202 Also fixes bug #4693.
2203 (reap_children): Decrease the job count for this second.
2204 (start_job_command): Increase the job count for this second.
2206 * read.c (conditional_line): Expand the text after ifn?def before
2207 checking to see if it's a single word. Fixes bug #7257.
2209 2004-01-09 Paul D. Smith <psmith@gnu.org>
2211 * file.c (print_file): Recurse to print all targets in
2212 double-colon rules. Fixes bug #4518, reported (with patch) by
2213 Andrew Chatham <chatham@google.com>.
2215 2004-01-07 Paul D. Smith <psmith@gnu.org>
2217 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2218 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2219 AC_FUNC_SETVBUF_REVERSED.
2221 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2222 (MAKE Variable): Fix Savannah bug #4898.
2224 * job.c (construct_command_argv_internal): Add "!" to the list of
2225 shell escape chars. POSIX sh allows it to appear before a
2226 command, to negate the exit code. Fixes bug #6404.
2228 * implicit.c (pattern_search): When matching an implicit rule,
2229 remember which dependencies have the ignore_mtime flag set.
2230 Original fix provided in Savannah patch #2349, by Benoit
2231 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2233 2003-11-22 Paul D. Smith <psmith@gnu.org>
2235 * README.W32.template (Outputs): Clarification on -j with
2236 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2239 2003-11-02 Paul D. Smith <psmith@gnu.org>
2241 * function.c (func_if): Strip all the trailing whitespace from the
2242 condition, then don't expand it. Fixed bug # 5798.
2244 * expand.c (recursively_expand_for_file): If we're expanding a
2245 variable with no file context, then use the variable's context.
2248 2003-10-21 Paul D. Smith <psmith@gnu.org>
2250 * main.c (log_working_directory): Add newlines to printf()s.
2252 * README.cvs: Add a note to ignore warnings during autoreconf.
2254 * maintMakefile (po_repo): Set a new URL for PO file updates.
2255 (get-config/config.guess get-config/config.sub): Get these files
2256 from the Savannah config project instead of ftp.gnu.org.
2258 2003-10-05 Paul Eggert <eggert@twinsun.com>
2260 * main.c (main): Avoid potential subscript error if environ has
2263 2003-08-22 Paul D. Smith <psmith@gnu.org>
2265 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2266 systems which don't yet implement the C89 standard :-/.
2268 2003-07-18 Paul D. Smith <psmith@gnu.org>
2270 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2271 [WINDOWS32]: Initialize hash.
2273 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2275 * dir.c (read_dirstream): Provide a workaround for broken versions of
2276 the MinGW dirent structure.
2278 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2280 * w32/include/dirent.h: Add __MINGW32__ filter.
2282 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2284 * make.h: Add global declaration of *make_host.
2285 * main.c (print_usage): Remove local declaration of *make_host.
2286 (print_version): Display "This program built for ..." after Copyright
2289 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2291 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2292 execution of "makeinfo --html make.texi".
2294 2003-04-30 Paul D. Smith <psmith@gnu.org>
2296 * build.template: Make some changes to maybe allow this script to
2297 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2299 * README.OS2.template: New file for OS/2 support. Original
2300 contributed by Andreas Buening.
2301 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2304 2003-04-19 Paul D. Smith <psmith@gnu.org>
2306 Fix bug #1405: allow a target to match multiple pattern-specific
2309 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2310 variable.c, where they've always belonged.
2311 * rule.h: Move the prototypes and struct pattern_var as well.
2312 * variable.c (initialize_file_variables): Invoke
2313 lookup_pattern_var() in a loop, until no more matches are found.
2314 If a match is found, create a new variable set for the target's
2315 pattern variables. Then merge the contents of each matching
2316 pattern variable set into the target's pattern variable set.
2317 (lookup_pattern_var): Change this function to be usable
2318 in a loop. It takes a starting position: if NULL, start at the
2319 beginning; if non-NULL, start with the pattern variable after that
2320 position, and return the next matching pattern.
2321 (create_pattern_var): Create a unique instance of
2322 pattern-specific variables for every definition in the makefile.
2323 Don't combine the same pattern together. This allows us to
2324 process the variable handling properly even when the same pattern
2325 is used multiple times.
2326 (parse_variable_definition): New function: break out the parsing
2327 of a variable definition line from try_variable_definition.
2328 (try_variable_definition): Call parse_variable_definition to
2330 (print_variable_data_base): Print out pattern-specific variables.
2331 * variable.h (struct variable): Remember when a variable is
2332 conditional. Also remember its flavor.
2333 (struct pattern_var): Instead of keeping a variable set, we just
2334 keep a single variable for each pattern.
2335 * read.c (record_target_var): Each pattern variable contains only a
2336 single variable, not a set, so create it properly.
2337 * doc/make.texi (Pattern-specific): Document the new behavior.
2339 2003-04-17 Paul D. Smith <psmith@gnu.org>
2341 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2342 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2343 file/directory naming rules for VMS so I can't tell whether this
2346 2003-04-09 Paul D. Smith <psmith@gnu.org>
2348 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2349 DOS-style pathnames: backslash separators and drive specifiers.
2351 2003-03-28 Paul D. Smith <psmith@gnu.org>
2353 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2354 the intermediate flag on all targets. Fixes bug #2515.
2356 2003-03-24 Paul D. Smith <psmith@gnu.org>
2358 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2359 Upgrade to autoconf 2.57 and automake 1.7.3.
2361 * job.c: More OS/2 changes from Andreas Buening.
2363 * file.c (print_file): Fix variable initialization.
2366 * remake.c (notice_finished_file):
2368 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2369 some calls (like readdir()) return NULL in valid situations
2370 without resetting errno. Fixes bug #2846.
2372 2003-02-25 Paul D. Smith <psmith@gnu.org>
2374 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2376 * job.c (_is_unixy_shell) [OS/2]: New function.
2377 Set default shell to /bin/sh.
2378 (reap_children): Close the job_rfd pipe here since we don't use a
2380 (set_child_handler_action_flags): define this to empty on OS/2.
2381 (start_job_command): Close the jobserver pipe and use
2382 child_execute_job() instead of fork/exec.
2383 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2384 rather than exec'ing, then reconfigure stdin/stdout.
2385 (exec_command): Rewrite to use spawn instead of exec. Return the
2388 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2389 in DOS. Handle the TEMP environment variable as in DOS. Don't
2390 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2391 use -j in DOS mode. Use child_execute_job() instead of
2394 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2397 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2398 prototypes that return values.
2400 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2402 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2403 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2405 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2408 2003-02-24 Paul D. Smith <psmith@gnu.org>
2410 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2411 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2412 (child_execute_job) [VMS]: Handle error status properly.
2413 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2415 * function.c (func_shell): Use EINTRLOOP() while reading from the
2416 subshell pipe (Fixes bug #2502).
2417 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2419 * main.c (main): Ditto.
2421 2003-01-30 Paul D. Smith <psmith@gnu.org>
2423 * read.c (eval): eval() was not fully reentrant, because the
2424 collapsed buffer was static. Change it to be an automatic
2425 variable so that eval() can be invoked recursively.
2427 (eval): Apply patch # 1022: fix memory reference error on long
2428 target-specific variable lines.
2429 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2431 * function.c (check_numeric): Combine the is_numeric() function
2432 into this function, since it's only called from one place.
2433 Constify this function. Have it print the incorrect string in the
2434 error message. Fixes bug #2407.
2435 (strip_whitespace): Constify.
2436 (func_if): Constify.
2437 * expand.c (expand_argument): Constify.
2439 2003-01-29 Paul D. Smith <psmith@gnu.org>
2441 Fix bug # 2169, also reported by other people on various systems.
2443 * make.h: Some systems, such as Solaris and PTX, do not fully
2444 implement POSIX-compliant SA_RESTART functionality; important
2445 system calls like stat() and readdir() can still fail with EINTR
2446 even if SA_RESTART has been set on the signal handler. So,
2447 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2448 EINTR for system calls which return -1 or 0 (NULL), respectively,
2450 Also, remove the old atomic_stat()/atomic_readdir() and
2451 HAVE_BROKEN_RESTART handling.
2453 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2455 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2456 * remake.c (touch_file): Ditto.
2458 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2459 * read.c (construct_include_path): Ditto.
2460 * remake.c (name_mtime): Ditto.
2461 * vpath.c (selective_vpath_search): Ditto.
2462 * dir.c (find_directory): Ditto.
2463 (local_stat): Ditto.
2464 (find_directory): Use ENULLLOOP() to wrap opendir().
2465 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2467 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2468 atomic_readdir() handling.
2470 2003-01-22 Paul D. Smith <psmith@gnu.org>
2472 * function.c (func_call): Fix Bug #1744. If we're inside a
2473 recursive invocation of $(call ...), mask any of the outer
2474 invocation's arguments that aren't used by this one, so that this
2475 invocation doesn't "inherit" them accidentally.
2477 2002-12-05 Paul D. Smith <psmith@gnu.org>
2479 * function.c (subst_expand): Valery Khamenia reported a
2480 pathological performance hit when doing substitutions on very
2481 large values with lots of words: turns out we were invoking
2482 strlen() a ridiculous number of times. Instead of having each
2483 call to sindex() call strlen() again, keep track of how much of
2484 the text we've seen and pass the length to sindex().
2486 2002-11-19 Paul D. Smith <psmith@gnu.org>
2488 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2491 2002-11-16 Paul D. Smith <psmith@gnu.org>
2493 * NMakefile.template (OBJS): Add hash.c object file.
2494 * SMakefile.template (srcs): Ditto.
2495 * Makefile.ami (objs): Ditto.
2496 * build_w32.bat: Ditto.
2498 * Makefile.DOS.template: Remove extra dependencies.
2500 2002-10-25 Paul D. Smith <psmith@gnu.org>
2502 * expand.c (install_variable_buffer): New function. Install a new
2503 variable_buffer context and return the previous one.
2504 (restore_variable_buffer): New function. Free the current
2505 variable_buffer context and put a previously saved one back.
2506 * variable.h: Prototypes for {install,restore}_variable_buffer.
2507 * function.c (func_eval): Push a new variable_buffer context
2508 before we eval, then restore the old one when we're done.
2511 * read.c (install_conditionals): New function. Install a new
2512 conditional context and return the previous one.
2513 (restore_conditionals): New function. Free the current
2514 conditional context and put a previously saved one back.
2515 (eval): Use the {install,restore}_conditionals for "include"
2517 (eval_buffer): Use {install,restore}_conditionals to preserve the
2518 present conditional state before we evaluate the buffer.
2521 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2523 (Recursion): Add a variable index entry for CURDIR.
2525 * README.cvs: Update to appropriate versions.
2526 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2527 don't need to copy loadavg.c: automake is smart enough to create
2528 it for me. Still have a bug in automake related to ansi2knr tho.
2530 2002-10-14 Paul D. Smith <psmith@gnu.org>
2532 * remake.c (notice_finished_file): Only touch targets if they have
2533 at least one command (as per POSIX). Resolve Bug #1418.
2535 * *.c: Convert to using ANSI C-style function definitions.
2536 * Makefile.am: Enable the ansi2knr feature of automake.
2537 * configure.in: ditto.
2539 2002-10-13 Paul D. Smith <psmith@gnu.org>
2541 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2542 for automatic variable values like $^, etc. In the case of very
2543 large lists of prerequisites this causes problems. Instead reuse
2544 a static buffer (resizeable) for each variable.
2546 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2547 target-specific variable definitions. Check for it and set an
2549 (record_target_var): Set the export field to v_export if the
2550 "exported" flag is set.
2551 * doc/make.texi (Target-specific): Document the ability to use
2554 * doc/make.texi: Change the name of the section on automatic
2555 variables from "Automatic" to "Automatic Variables". Added text
2556 clarifying the scope of automatic variables.
2558 2002-10-04 Paul D. Smith <psmith@gnu.org>
2560 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2562 (record_files): Ditto.
2564 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2565 the search for the '=' to only within the enclosing parens.
2567 2002-10-03 Paul D. Smith <psmith@gnu.org>
2569 Version 3.80 released.
2571 * dir.c: Change hash functions to use K&R function definition style.
2572 * function.c: Ditto.
2574 * variable.c: Ditto.
2576 Update to automake 1.7.
2578 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2579 (pdf): Remove this target as automake now provides one.
2581 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2583 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2585 * makefile.com: Updates for GNU make 3.80.
2586 * makefile.vms: Ditto.
2588 2002-09-23 Paul D. Smith <psmith@gnu.org>
2590 * read.c (enum make_word_type): Remove w_comment.
2591 (get_next_mword): Don't treat comment characters as special; where
2592 this function is used we will never see a comment (it's stripped
2593 before we get here) and treating comments specially means that
2594 targets like "foo\#bar" aren't handled properly.
2596 2002-09-18 Paul D. Smith <psmith@gnu.org>
2598 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2600 * read.c (eval): Expansion of arguments to export/unexport was
2601 ignoring all arguments after the first one. Change the algorithm
2602 to expand the whole line once, then parse the results.
2604 2002-09-17 Paul D. Smith <psmith@gnu.org>
2606 Fix Bug #940 (plus another bug I found while looking at this):
2608 * read.c (record_target_var): enter_file() will add a new entry if
2609 it's a double-colon target: we don't want to do that in this
2610 situation. Invoke lookup_file() and only enter_file() if it does
2611 not already exist. If the file we get back is a double-colon then
2612 add this variable to the "root" double-colon target.
2614 * variable.c (initialize_file_variables): If this file is a
2615 double-colon target but is not the "root" target, then initialize
2616 the root and make the root's variable list the parent of our
2619 2002-09-13 Paul D. Smith <psmith@gnu.org>
2621 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2623 * hash.c (round_up_2): Get rid of a warning.
2625 2002-09-12 Paul D. Smith <psmith@gnu.org>
2627 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2628 so it doesn't complain about getloadavg.c.
2630 * commands.c (set_file_variables): Make sure we always alloca() at
2631 least 1 character for the value of $? (for '\0').
2633 2002-09-11 Paul D. Smith <psmith@gnu.org>
2635 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2636 macro to use RESULT instead of the incorrect _RESULT_.
2638 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2639 and atomic_readdir(). We need to #include dirent.h to get this to
2641 * misc.c (atomic_readdir): Fix typos.
2643 2002-09-10 Paul D. Smith <psmith@gnu.org>
2645 * read.c (eval): Expand variable lists given to export and
2646 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2647 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2649 * doc/make.texi (Variables/Recursion): Document this.
2650 (Conditional Syntax): And here.
2652 2002-09-09 Paul D. Smith <psmith@gnu.org>
2654 * configure.in: Check for memmove().
2656 2002-09-07 Paul D. Smith <psmith@gnu.org>
2658 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2659 Michael Sterrett <msterret@coat.com> reports that while it has
2660 SA_RESTART, it does not work properly.
2662 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2663 that invokes stat() and loops to do it again if it returns EINTR.
2664 (atomic_readdir): Ditto, with readdir().
2666 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2667 and readdir() to atomic_stat() and atomic_readdir().
2669 2002-09-04 Paul D. Smith <psmith@gnu.org>
2671 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2672 reports that GNU make sometimes doesn't recognize that targets can
2673 be made, when directories can be created as prerequisites. He
2674 reports that changing the order of predicates in the DEP->changed
2675 flag test so that lookup_file() is always performed, solves this
2678 2002-08-08 Paul D. Smith <psmith@gnu.org>
2680 * configure.in: Require a newer version of gettext.
2682 * misc.c (perror_with_name): Translate the format string (for
2683 right-to-left language support).
2684 (pfatal_with_name): Ditto.
2686 * main.c: Create a static array of strings to store the usage
2687 text. This is done to facilitate translations.

2689 (switches): Remove values for obsolete fields.
2690 (print_usage): Print each element of the usage array.
2692 * hash.c: Change function definitions to be K&R style.
2694 2002-08-02 Paul D. Smith <psmith@gnu.org>
2696 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2697 this one because it's too hard to get right. We'll look at it for
2699 * main.c (main): Don't create the .TARGETS variable.
2700 * variable.c (handle_special_var): Don't handle .TARGETS.
2702 2002-08-01 Paul D. Smith <psmith@gnu.org>
2704 * main.c (switches): Add a new option, -B (--always-make). If

2706 if they don't appear to be out of date.
2707 (always_make_flag): New flag.
2708 * make.h: Extern always_make_flag.
2709 * remake.c (update_file_1): Check always_make_flag; if it's set we
2710 will always rebuild any target we can, even if none of its
2711 prerequisites are newer.
2714 * doc/make.texi (Shell Function): Make it clear that make
2715 variables marked as "export" are not passed to instances of the
2718 Add new introspection variable .VARIABLES and .TARGETS.
2720 * variable.c (handle_special_var): New function. If the variable
2721 reference passed in is "special" (.VARIABLES or .TARGETS),
2722 calculate the new value if necessary. .VARIABLES is handled here:
2723 walk through the hash of defined variables and construct a value
2724 which is a list of the names. .TARGETS is handled by
2725 build_target_list().
2726 (lookup_variable): Invoke handle_special_var().
2727 * file.c (build_target_list): Walk through the hask of known files
2728 and construct a list of the names of all the ones marked as
2730 * main.c (main): Initialize them to empty (and as simple variables).
2731 * doc/make.texi (Special Variables): Document them.
2732 * NEWS: Mention them.
2734 * variable.h (struct variable): Add a new flag "exportable" which
2735 is true if the variable name is valid for export.
2736 * variable.c (define_variable_in_set): Set "exportable" when a new
2737 variable is defined.
2738 (target_environment): Use the "exportable" flag instead of
2739 re-checking the name here... an efficiency improvement.
2741 2002-07-31 Paul D. Smith <psmith@gnu.org>
2743 * config.h-vms.template: Updates to build on VMS. Thanks to
2744 Brian_Benning@aksteel.com for helping verify the build.
2745 * makefile.com: Build the new hash.c file.
2746 * hash.h: Use strcpmi(), not stricmp(), in the
2747 HAVE_CASE_INSENSITIVE_FS case.
2749 2002-07-30 Paul D. Smith <psmith@gnu.org>
2751 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2752 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2753 Reported by <Brian_Benning@aksteel.com>.
2755 2002-07-10 Paul D. Smith <psmith@gnu.org>
2757 * variable.c (pop_variable_scope): Remove variable made unused by
2758 new hash infrastructure.
2759 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2760 comparisons as well as name comparisons.
2761 * variable.h: Add a prototype for new hash_init_function_table().
2762 * file.c (lookup_file): Remove variables made unused by new hash
2764 * dir.c (directory_contents_hash_2): Missing return of hash value.
2765 (dir_contents_file_exists_p): Remove variables made unused by new
2766 hash infrastructure.
2769 Installed Greg McGary's integration of the hash functions from the
2770 GNU id-utils package:
2772 2002-07-10 Greg McGary <greg@mcgary.org>
2774 * scripts/functions/filter-out: Add literals to to the
2775 pattern space in order to add complexity, and trigger
2776 use of an internal hash table. Fix documentation strings.
2777 * scripts/targets/INTERMEDIATE: Reverse order of files
2778 passed to expected `rm' command.
2780 2002-07-10 Greg McGary <greg@mcgary.org>

2872 2002-07-10 Paul D. Smith <psmith@gnu.org>
2874 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2875 prerequisite list. A real SysV make will expand the entire
2876 prerequisites list _twice_: we don't do that as it's a big
2877 backward-compatibility problem. We only replace those specific
2880 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2881 references left in the list of prerequisites. Check for .POSIX as
2882 we record targets, so we can disable non-POSIX behavior while
2883 reading makefiles as well as running them.
2884 (eval): Check the prerequisite list to see if we have anything
2885 that looks like a SysV prerequisite variable reference.
2887 2002-07-09 Paul D. Smith <psmith@gnu.org>
2889 * doc/make.texi (Prerequisite Types): Add a new section describing
2890 order-only prerequisites.
2892 * read.c (uniquize_deps): If we have the same file as both a
2893 normal and order-only prereq, get rid of the order-only prereq,
2894 since the normal one supersedes it.
2896 2002-07-08 Paul D. Smith <psmith@gnu.org>
2898 * AUTHORS: Added Greg McGary to the AUTHORS file.
2899 * NEWS: Blurbed order-only prerequisites.
2900 * file.c (print_file): Show order-only deps properly when printing
2903 * maintMakefile: Add "update" targets for wget'ing the latest
2904 versions of various external files. Taken from Makefile.maint in
2907 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2908 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2910 2002-07-07 Paul D. Smith <psmith@gnu.org>
2912 * po/*.po: Remove. We'll use wget to retrieve them at release
2915 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2916 rather than a shell you get an exception. Make sure we look up
2917 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2919 * remake.c (notice_finished_file): Fix handling of -t flag.
2920 Patch provided by Henning Makholm <henning@makholm.net>.
2922 * implicit.c (pattern_search): Some systems apparently run short
2923 of stack space, and using alloca() in this function caused an
2924 overrun. I modified it to use xmalloc() on the two variables
2925 which seemed like they might get large. Fixes Bug #476.
2927 * main.c (print_version): Update copyright notice to conform with
2929 (print_usage): Update help output.
2931 * function.c (func_eval): Create a new make function, $(eval
2932 ...). Expand the arguments, put them into a buffer, then invoke
2933 eval_buffer() on the resulting string.
2934 (func_quote): Create a new function, $(quote VARNAME). Inserts
2935 the value of the variable VARNAME without expanding it any
2938 * read.c (struct ebuffer): Change the linebuffer structure to an
2939 "eval buffer", which can be either a file or a buffer.
2940 (eval_makefile): Move the code in the old read_makefile() which
2941 located a makefile into here: create a struct ebuffer with that
2942 information. Have it invoke the new function eval() with that
2944 (eval_buffer): Create a new function that creates a struct ebuffer
2945 that holds a string buffer instead of a file. Have it invoke
2946 eval() with that ebuffer.
2947 (eval): New function that contains the guts of the old
2948 read_makefile() function: this function parses makefiles. Obtains
2949 data to parse from the provided ebuffer. Some modifications to
2950 make the flow of the function cleaner and clearer. Still could
2951 use some work here...
2952 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2953 contents of the define/endef variable from the ebuffer.
2954 (readstring): Read the next line from a string-style ebuffer.
2955 (readline): Read the next line from an ebuffer. If it's a string
2956 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2959 * dep.h (eval_buffer): Prototype eval_buffer();
2961 * variable.c (do_variable_definition): Make sure that all
2962 non-target-specific variables are registered in the global set.
2963 If we're invoked from an $(eval ...) we might be inside a $(call
2964 ...) or other function which has pushed a variable scope; we still
2965 want to define our variables from evaluated makefile code in the
2968 2002-07-03 Greg McGary <greg@mcgary.org>
2970 * dep.h (struct dep) [ignore_mtime]: New member.
2971 [changed]: convert to a bitfield.
2972 * implicit.c (pattern_search): Zero ignore_mtime.
2973 * main.c (main, handle_non_switch_argument): Likewise.
2974 * rule.c (convert_suffix_rule): Likewise.
2975 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2976 (read_makefile): Parse '|' in prerequisite list.
2977 (uniquize_deps): Consider ignore_mtime when comparing deps.
2978 * remake.c (update_file_1, check_dep): Don't force remake for
2979 dependencies that have d->ignore_mtime.
2980 * commands.c (FILE_LIST_SEPARATOR): New constant.
2981 (set_file_variables): Don't include a
2982 prerequisite in $+, $^ or $? if d->ignore_mtime.
2985 2002-06-18 Paul D. Smith <psmith@gnu.org>
2987 * make.texinfo: Updates for next revision. New date/rev/etc.
2988 Recreate all Info menus. Change license on the manual to the GNU
2989 Free Documentation License. A number of typos.
2990 (Variables Simplify): Don't use "-" before it's defined.
2991 (Automatic Prerequisites): Rewrite the target example to work
2992 properly if the compile fails. Remove incorrect comments about
2993 how "set -e" behaves.
2994 (Text Functions): Move the "word", "wordlist", "words", and
2995 "firstword" functions here, from "File Name Functions".
2996 * make-stds.texi: Update from latest GNU version.
2997 * fdl.texi: (created) Import the latest GNU version.
2999 2002-06-06 Paul D. Smith <psmith@gnu.org>
3001 * variable.c (do_variable_definition): New function: extract the
3002 part of try_variable_definition() that actually sets the value
3003 into a separate function.
3004 (try_variable_definition): Call do_variable_definition() after
3005 parsing the variable definition string.
3006 (define_variable_in_set): Make the name argument const.
3008 * variable.h (enum variable_flavor): Make public.
3009 (do_variable_definition): Create prototype.
3011 * read.c (read_all_makefiles): Create a new built-in variable,
3013 (read_makefile): Add each makefile read in to this variable value.
3015 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3017 * Makefile.DOS.template: Tweak according to changes in the
3018 distribution. Add back the dependencies of *.o files.
3020 * configh.dos.template: Synchronize with config.h.in.
3022 2002-05-09 Paul D. Smith <psmith@gnu.org>
3024 * file.c (file_timestamp_now): Use K&R function declaration.
3026 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3027 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3028 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3029 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3030 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3031 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3032 nlist.n_name is a pointer rather than an array.
3034 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3035 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3036 * configure.in: Use it instead of the old version.
3038 * main.c (main): Prefer setvbuf() to setlinebuf().
3040 2002-05-08 Paul D. Smith <psmith@gnu.org>
3042 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3043 (loadavg_LDADD): Ditto.
3045 2002-04-29 Paul D. Smith <psmith@gnu.org>
3047 * expand.c (recursively_expand_for_file): Rename
3048 recursively_expand() to recursively_expand_for_file() and provide
3049 an extra argument, struct file. If the argument is provided, set
3050 the variable scope to that of the file before expanding.
3051 * variable.h (recursively_expand): Make this a macro that invokes
3052 recursively_expand_for_file() with a NULL file pointer.
3053 * variable.c (target_environment): Call the renamed function and
3054 provide the current file context.
3055 Fixes Debian bug #144306.
3057 2002-04-28 Paul D. Smith <psmith@gnu.org>
3059 Allow $(call ...) user-defined variables to be self-referencing
3060 without throwing an error. Allows implementation of transitive
3061 closures, among other possibly useful things.
3062 Requested by: Philip Guenther <guenther@sendmail.com>
3064 * variable.h (struct variable): Add a new field: exp_count, and
3065 new macros to hold its size and maximum value.
3066 (warn_undefined): Make this a macro.
3067 * variable.c (define_variable_in_set): Initialize it.
3068 * expand.c (recursively_expand): If we detect recursive expansion
3069 of a variable, check the exp_count field. If it's greater than 0
3070 allow the recursion and decrement the count.
3071 (warn_undefined): Remove this (now a macro in variable.h).
3072 * function.c (func_call): Before we expand the user-defined
3073 function, modify its exp_count field to contain the maximum
3074 number of recursive calls we'll allow. After the call, reset it
3077 2002-04-21 Paul D. Smith <psmith@gnu.org>
3079 Modified to use latest autoconf (2.53), automake (1.6.1), and
3080 gettext (0.11.1). We're using gettext's new "external" support,
3081 to avoid including libintl source with GNU make.
3083 * README.cvs: New file. Explain how to build GNU make from CVS.
3085 * configure.in: Modify checking for the system glob library.
3086 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3087 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3088 etc. will manage it correctly). Set an automake conditional
3089 USE_LOCAL_GLOB to decide whether to compile the glob library.
3091 * getloadavg.c (main): Include make.h in the "TEST" program to
3094 * Makefile.am: Remove special rules for loadavg. Replace them
3095 with Automake capabilities for building extra programs.
3097 * signame.c: This file does nothing if the system provide
3098 strsignal(). If not, it implements strsignal(). If the system
3099 doesn't define sys_siglist, then we make our own; otherwise we use
3101 * signame.h: Removed.
3103 * main.c (main): No need to invoke signame_init(). Update copyright.
3105 * ABOUT-NLS: Removed.
3106 * gettext.c: Removed.
3107 * gettext.h: Get a simplified copy from the gettext package.
3109 * i18n/*.po: Moved to po/.
3112 * config/*: Created. Contains package configuration helper files.
3113 * config.guess, config.sub: Moved to config directory.
3115 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3116 Rework to use new-style autoconf features. Use the "external"
3117 mode for gettext. Make the build.sh config file conditional on
3118 whether build.sh.in exists, to avoid autoconf errors.
3119 * acinclude.m4: Removed almost all macros as being obsolete.
3120 Rewrote remaining macros to use AC_DEFINE.
3121 * acconfig.h: Removed.
3123 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3124 conditional to handle customs support. Remove special handling
3127 2002-04-20 Paul D. Smith <psmith@gnu.org>
3129 * function.c (func_call): Don't mark the argument variables $1,
3130 etc. as recursive. They've already been fully expanded so
3131 there's no need to do it again, and doing so strips escaped $'s.
3132 Reported by Sebastian Glita <glseba@yahoo.com>.
3134 * remake.c (notice_finished_file): Walk through double-colon
3135 entries via the prev field, not the next field!
3136 Reported by Greg McGary <greg@mcgary.org>.
3138 * main.c (main): If the user specifies -q and asks for a specific
3139 target which is a makefile, we got an assert. In that case it
3140 turns out we should continue normally instead.
3142 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3144 * i18n/he.po: Installed a new translation.
3146 2002-01-07 Paul D. Smith <psmith@gnu.org>
3148 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3150 2001-12-04 Paul D. Smith <psmith@gnu.org>
3152 * i18n/ja.po: Installed an updated translation.
3154 2001-09-06 Paul Eggert <eggert@twinsun.com>
3156 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3157 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3159 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3161 (main): Get rid of any avoidable limit on stack size.
3163 2001-09-04 Paul D. Smith <psmith@gnu.org>
3165 * i18n/da.po: Installed an updated translation.
3167 2001-08-03 Paul D. Smith <psmith@gnu.org>
3169 * i18n/fr.po: Installed an updated translation.
3170 Resolves Debian bug #106720.
3172 2001-06-13 Paul D. Smith <psmith@gnu.org>
3174 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3177 2001-06-11 Paul D. Smith <psmith@gnu.org>
3179 * i18n/ko.po: Installed a new translation.
3181 2001-05-06 Paul D. Smith <psmith@gnu.org>
3183 Modify the EINTR handling.
3185 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3186 the way in which we manage the file descriptor/signal handler race
3187 trap to be more efficient.
3189 2001-05-06 Paul Eggert <eggert@twinsun.com>
3191 Restart almost all system calls that are interrupted, instead
3192 of worrying about EINTR. The lone exception is the read() for
3195 * configure.in (HAVE_SA_RESTART): New macro.
3196 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3197 * main.c (main): Use SA_RESTART instead of the old,
3198 nonstandard SA_INTERRUPT.
3200 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3201 * main.c (bsd_signal): New function or macro,
3202 if the implementation doesn't supply it.
3203 (The bsd_signal function will be in POSIX 1003.1-200x.)
3204 (HANDLESIG): Remove.
3205 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3207 * make.h (EINTR_SET): Remove.
3208 (SA_RESTART): New macro.
3210 * arscan.c (ar_member_touch): Don't worry about EINTR.
3211 * function.c (func_shell): Likewise.
3212 * job.c (reap_children, free_child, new_job): Likewise.
3213 * main.c (main): Likewise.
3214 * remake.c (touch_file, name_mtime): Likewise.
3216 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3217 if fstat failed with errno!=EINTR, the error was ignored.
3219 * job.c (set_child_handler_action_flags): New function.
3220 (new_job): Use it to temporarily clear the SIGCHLD action flags
3221 while reading the token.
3223 2001-05-02 Paul D. Smith <psmith@gnu.org>
3225 * job.c (start_job_command): Don't add define/endef per-line flags
3226 to the top-level flags setting.
3228 2001-04-03 Paul D. Smith <psmith@gnu.org>
3230 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3231 bit on error, so check for odd return values, not non-0 return
3233 (VMS_get_member_info): Calculate the timezone differences correctly.
3234 Reported by John Fowler <jfowler@nyx.net>.
3237 2001-03-14 Paul D. Smith <psmith@gnu.org>
3239 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3240 value before invoking define_variable().
3241 Reported by John Fowler <jfowler@nyx.net>.
3243 2001-02-07 Paul D. Smith <psmith@gnu.org>
3245 * read.c (record_target_var): If we reset the variable due to a
3246 command-line variable setting overriding it, turn off the "append"
3249 2001-01-17 Paul D. Smith <psmith@gnu.org>
3251 * variable.c (lookup_variable) [VMS]: When getting values from the
3252 environment, allocate enough space for the _value_ plus escapes,
3253 not enough space for the name plus escapes :-/.
3254 Reported by John Fowler <jfowler@nyx.net>.
3256 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3257 warnings that make generates, so it doesn't look like an error.
3258 Reported by Karl Berry <karl@gnu.org>.
3261 Fix for PR/2020: Rework appended target-specific variables. I'm
3262 fairly confident this algorithm is finally correct.
3264 * expand.c (allocated_variable_append): Rewrite. Instead of
3265 expanding each appended variable then adding all the expanded
3266 strings together, we append all the unexpanded values going up
3267 through the variable set contexts, then expand the final result.
3268 This behaves just like non-target-specific appended variable
3269 values, while the old way didn't in various corner cases.
3270 (variable_append): New function: recursively append the unexpanded
3271 value of a variable, walking from the outermost variable scope to
3273 * variable.c (lookup_variable): Remove the code that looked up the
3274 variable set list if the found variable was "append". We don't
3276 (lookup_variable_in_set): Make this non-static so we can use it
3278 (try_variable_definition): Use lookup_variable_in_set() rather
3279 than faking out current_variable_set_list by hand (cleanup).
3280 * variable.h: Add a prototype for the now non-static
3281 lookup_variable_in_set().
3283 2000-11-17 Paul D. Smith <psmith@gnu.org>
3285 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3286 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3287 before throwing a fit.
3289 2000-11-17 Paul D. Smith <psmith@gnu.org>
3291 * read.c (readline): CRLF calculations had a hole, if you hit the
3292 buffer grow scenario just right. Reworked the algorithm to avoid
3293 the need for len or lastlen at all. Problem description with
3294 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3296 2000-10-24 Paul D. Smith <psmith@gnu.org>
3298 * gettext.c (SWAP): Declare this with the prototype, otherwise
3299 some systems don't work (non-32-bit? Reported for Cray T3E).
3300 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3302 2000-10-05 Paul D. Smith <psmith@gnu.org>
3304 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3305 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3307 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3309 2000-09-22 Paul D. Smith <psmith@gnu.org>
3311 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3312 parts of the real gettext.h here, and we expect to really include
3313 the real gettext.h later. If we keep this #define, it's ignored.
3315 2000-09-21 Paul D. Smith <psmith@gnu.org>
3317 * main.c (log_working_directory): Rework the text to use complete
3318 sentences, to make life simpler for the translators.
3320 2000-08-29 Paul D. Smith <psmith@gnu.org>
3322 * file.c (remove_intermediates): Print a debug message before we
3323 remove intermediate files, so the user (if she uses -d) knows
3326 2000-08-21 Paul D. Smith <psmith@gnu.org>
3328 * variable.c (try_variable_definition): Change how we handle
3329 target-specific append variable defns: instead of just setting the
3330 value, expand it as an append _but_ only within the current
3331 target's context. Otherwise we lose all but the last value if the
3332 variable is appended more than once within the current target
3333 context. Fixes PR/1831.
3335 2000-08-16 Paul D. Smith <psmith@gnu.org>
3337 * function.c (func_shell): Nul-terminate the buffer before
3338 printing an exec error message (just in case it's not!).
3339 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3341 2000-07-25 Paul D. Smith <psmith@gnu.org>
3343 * job.c (construct_command_argv_internal): Add "~" to the list of
3344 sh_chars[] which disallow optimizing out the shell call.
3346 2000-07-23 Paul Eggert <eggert@twinsun.com>
3348 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3349 supersedes --disable-nsec-timestamps.
3350 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3351 * README: Remove --disable-nsec-timestamps.
3353 * filedef.h (struct file.low_resolution_time): New member.
3354 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3355 * remake.c (update_file_1):
3356 Avoid spurious rebuilds due to low resolution time stamps,
3357 generalizing the earlier code that applied only to archive members.
3358 (f_mtime): Archive members always have low resolution time stamps.
3360 * configure.in: Remove --disable-nsec-timestamps, as this has
3361 been superseded by .LOW_RESOLUTION_TIME.
3363 2000-07-23 Paul Eggert <eggert@twinsun.com>
3365 * configure.in (enable_nsec_timestamps): Renamed from
3366 make_cv_nsec_timestamps, since enable/disable options
3367 shouldn't be cached.
3369 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3370 and Paul Eggert <eggert@twinsun.com>
3372 * file.c (file_timestamp_now):
3373 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3374 so that clock_gettime is not linked unless needed.
3376 * filedef.h (FILE_TIMESTAMP_HI_RES):
3377 Remove definition; "configure" now does this.
3379 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3380 to before high resolution file timestamp check,
3381 since that check now uses uintmax_t.
3382 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3383 high resolution file timestamps.
3384 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3385 so that we don't link in clock_gettime unnecessarily.
3387 2000-07-17 Paul D. Smith <psmith@gnu.org>
3389 * i18n/ja.po: New version of the translation file.
3391 2000-07-07 Paul D. Smith <psmith@gnu.org>
3393 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3394 the offset calculation.
3395 (name_mtime): Replace EINTR test with EINTR_SET macro.
3397 2000-07-07 Paul Eggert <eggert@twinsun.com>
3401 * remake.c (update_file_1):
3402 Avoid spurious rebuilds of archive members due to their
3403 timestamp resolution being only one second.
3404 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3405 the clock's resolution being lower than file timestamps'.
3406 When warning about future timestamps, report only the discrepancy,
3407 not the absolute value of the timestamp and the current time.
3409 * file.c (file_timestamp_now): New arg RESOLUTION.
3410 * filedef.h (file_timestamp_now): Likewise.
3411 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3413 2000-07-05 Paul D. Smith <psmith@gnu.org>
3415 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3416 to listp. Fixes PR/1793.
3418 2000-06-26 Paul Eggert <eggert@twinsun.com>
3420 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3422 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3424 * remake.c (f_mtime): Remove unused var memtime.
3426 2000-06-25 Martin Buchholz <martin@xemacs.org>
3428 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3429 Ran spell-check on make.texinfo.
3431 2000-06-23 Paul D. Smith <psmith@gnu.org>
3433 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3434 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3435 * make.h: Define these macros.
3437 * Version 3.79.1 released.
3439 * configure.in: Add a new option, --disable-nsec-timestamps, to
3440 avoid using sub-second timestamps on systems that support it. It
3441 can lead to problems, e.g. if your makefile relies on "cp -p".
3442 * README.template: Document the issue with "cp -p".
3444 * config.guess, config.sub: Updated.
