3 Rework the way secondary expansion is stored, for efficiency.
4 This changes secondary expansion so that ONLY WHEN we know we have
5 a possibility of needing secondary expansion, do we defer the
6 secondary expansion. This means more parsing the deps but we use
7 a lot less memory (due to the strcache). Also, this fixes
10 * read.c (eval): Don't parse the dep string here anymore.
11 (record_files): Take the dep argument as an unparsed string. If
12 secondary expansion is enabled AND the prereq string has a '$' in
13 it, then set NEED_2ND_EXPANSION and keep the entire string.
14 Otherwise, parse the dep string here to construct the dep list
15 with the names in the strcache.
17 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
18 duplicate the name string (others are in the strcache).
20 * implicit.c: Remove struct idep and free_idep_chain(): unused.
21 (struct patdeps): New structure to store prereq information.
22 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
23 which prerequisites need expansion, and expand only those.
25 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
26 and enter_prereqs(). split_prereqs() takes a fully-expanded string
27 and splits it into a DEP list, handling order-only prereqs.
28 (enter_prereqs): This function enters a list of DEPs into the file
29 database. If there's a stem defined, expand any pattern chars.
30 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
31 set. Use the above functions.
32 (snap_deps): Only perform second expansion on prereqs that need it,
33 as defined by the NEED_2ND_EXPANSION flag.
34 (print_prereqs): New function to print the prereqs
35 (print_file): Call print_prereqs() rather than print inline.
37 * hash.h (STRING_COMPARE): Take advantage of strcache() by
39 (STRING_N_COMPARE): Ditto.
40 (ISTRING_COMPARE): Ditto.
42 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
43 (parse_file_seq): Return void*
44 * read.c (parse_file_seq): Return void*.
45 (eval): Invoke macroized version of parse_file_seq()
46 * default.c (set_default_suffixes): Ditto.
47 * file.c (split_prereqs): Ditto.
48 * function.c (string_glob): Ditto.
49 * main.c (main): Ditto.
50 * rule.c (install_pattern_rule): Ditto.
52 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
54 2009-09-16 Paul Smith <psmith@gnu.org>
56 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
58 * dep.h: Create alloc_dep() / free_dep() macros.
60 * implicit.c (pattern_search): Take advantage of the new
61 parse_file_seq() to add the directory prefix to each prereq.
63 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
64 all. Avoid reversing chains. Support adding prefixes.
65 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
66 cached/non-cached results.
67 (eval): Remove multi_glob() & invoke new parse_file_seq().
68 * rule.c (install_pattern_rule): Ditto.
69 * main.c (main): Ditto.
70 * implicit.c (pattern_search): Ditto.
71 * function.c (string_glob): Ditto.
72 * file.c (parse_prereqs): Ditto.
73 * default.c (set_default_suffixes): Ditto.
75 * variable.c (parse_variable_definition): Don't run off the end of
76 the string if it ends in whitespace (found with valgrind).
78 * commands.c (set_file_variables): Keep space for all targets in
79 $? if -B is given (found with valgrind).
81 2009-09-15 Paul Smith <psmith@gnu.org>
83 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
84 (xcalloc): Add new function.
85 * make.h: New declarations.
87 * ar.c (ar_glob_match): New calling method for concat().
88 * main.c (main): Ditto.

90 * read.c (eval_makefile): Ditto.
91 (tilde_expand): Ditto.
92 (parse_file_seq): Ditto.
93 * variable.c (target_environment): Ditto.
94 (sync_Path_environment): Ditto.

97 * dir.c (file_impossible): Ditto.
98 * file.c (enter_file): Ditto.
99 * job.c (new_job): Ditto.
100 * read.c (parse_file_seq): Ditto.
101 * vmsfunctions.c (opendir): Ditto.
103 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
105 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
106 inside the loop that looks up environment for PATH.
108 2009-08-31 Eli Zaretskii <eliz@gnu.org>
110 * function.c (windows32_openpipe): Update envp after calling
111 sync_Path_environment.
113 2009-08-02 Paul Smith <psmith@gnu.org>
115 * remake.c (notice_finished_file): Ensure file->cmds is not null
116 before looping through them. Fixes Savannah bug #21824.
118 * doc/make.texi (Wildcard Examples): Clarify when objects is
119 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
120 (Include): Clarify the behavior of -include.
121 Fixes Savannah bug #18963.
123 2009-08-01 Paul Smith <psmith@gnu.org>
125 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
126 etc. come on the command line. Fixes Savannah bug #27093.
128 * expand.c (expand_argument): If the argument is large enough use
129 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
131 * variable.c (do_variable_definition): Avoid using alloca() to
132 hold values, which can be large. Fixes Savannah bug #23960.
134 * job.c (new_job): Use memmove() instead of strcpy() since both
135 pointers are in the same memory block. Fixes Savannah bug #27148.
136 Patch by Petr Machata.
138 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
140 * job.c (construct_command_argv_internal): Add "ulimit" and
141 "unset" to the sh_cmds for Unixy shells.
143 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
145 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
146 that set make_cv_sys_gnu_glob, so they are also correctly set
147 when the cache has been populated before.
149 2009-07-04 Eli Zaretskii <eliz@gnu.org>
151 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
152 exist, as realpath(3) does where it's supported.
154 2006-07-04 Eli Zaretskii <eliz@gnu.org>
156 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
157 (abspath): Support systems that define HAVE_DOS_PATHS (have
158 drive letters in their file names). Use IS_PATHSEP instead of a
159 literal '/' comparison. Fixes Savannah bug #26886.
161 2009-06-14 Paul Smith <psmith@gnu.org>
163 * remake.c (update_file_1): Remember the original file we marked
164 as updating, so we can clear that flag again. If we find a target
165 via vpath, FILE might change.
166 (check_dep): Ditto. Fixes Savannah bug #13529.
167 Patch by Reid Madsen <reid.madsen@tek.com>.
169 2009-06-13 Paul Smith <psmith@gnu.org>
171 * doc/make.texi (MAKEFILES Variable): Be explicit that files
172 included by MAKEFILES cannot give default goals.
173 * read.c (eval): If set_default is not set, pass the no-default-goal
174 value when we read included makefiles. Fixes Savannah bug #13401.
176 * ar.c (ar_name): Ensure that targets with empty parens aren't
177 considered archive member references: archive members must have a
178 non-empty "member" string. Fixes Savannah bug #18435.
180 * function.c (string_glob): Rely on multi_glob() to determine
181 whether files exist or not. Remove call to file_exists_p() which
182 is not always correct. Fixes Savannah bug #21231.
183 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
184 then only files that really exist will be returned.
185 * dep.h: Add new argument to multi_glob().
186 * rule.c (install_pattern_rule): Ditto.
187 * read.c (eval): Ditto.
188 * main.c (main): Ditto.
189 * implicit.c (pattern_search): Ditto.
190 * file.c (parse_prereqs): Ditto.
191 * default.c (set_default_suffixes): Ditto.
193 2009-06-09 Paul Smith <psmith@gnu.org>
195 * commands.c (set_file_variables): If always_make_flag is set,
196 always add the prereq to $?. Fixes Savannah bug #17825.
198 * remake.c (update_file_1): When rebuilding deps of FILE, also try
199 to rebuild the deps of all the also_make targets for that file.
200 Fixes Savannah bug #19108.
202 * implicit.c (pattern_search): Undo test for is_target, added by
203 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
204 Rule Search Algorithm". Fixes Savannah bug #17752.
206 * main.c (clean_jobserver): Clear the jobserver_fds options and
207 set job_slots to the default when we clean up.
208 (define_makeflags): Return the new MAKEFLAGS value.
209 (main): Reset MAKEFLAGS in the environment when we re-exec.
210 Fixes Savannah bug #18124.
212 2009-06-08 Paul Smith <psmith@gnu.org>
214 * read.c (eval): Collapse continuations post-semicolon on target-
215 specific variables. Fixes Savannah bug #17521.
217 2009-06-07 Paul Smith <psmith@gnu.org>
219 * job.c (reap_children): For older systems without waitpid() (are
220 there any of these left?) run wait(2) inside EINTRLOOP to handle
221 EINTR errors. Fixes Savannah bug #16401.
223 * (various): Debug message cleanup. Fixes Savannah bug #16469.
225 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
227 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
228 not the end, to catch second expansion $(eval ...) defining new
229 target/prereq relationships during snap_deps.
230 Fixes Savannah bug #24622.
232 * read.c (record_files): The second-expansion "f->updating" hack
233 was not completely correct: if assumed that the target with
234 commands always had prerequisites; if one didn't then the ordering
235 was messed up. Fixed for now to use f->updating to decide whether
236 to preserve the last element in the deps list... but this whole
237 area of constructing and reversing the deps list is too confusing
238 and needs to be reworked. Fixes Savannah bug #21198.
240 2009-06-06 Paul Smith <psmith@gnu.org>
242 * hash.c (hash_insert): Remove useless test for NULL.
243 Fixes Savannah bug #21823.
245 * make.h: Move SET_STACK_SIZE determination to make.h.
246 * main.c (main): New global variable, STACK_LIMIT, holds the
247 original stack limit when make was started.
248 * job.c (start_job_command): Reset the stack limit, if we changed it.
249 Fixes Savannah bug #22010.
251 * remake.c (check_dep): Only set the target's state to not-started
252 if it's not already running. Found this while testing -j10 builds
253 of glibc: various targets were being rebuilt multiple times.
254 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
257 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
258 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
261 2009-06-04 Paul Smith <psmith@gnu.org>
263 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
265 * maintMakefile: Modify access of config and gnulib Savannah
266 modules to use GIT instead of CVS.
268 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
269 Fixes Savannah bug #24655.
271 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
272 this can happen during some invocations of $(eval ...) for example.
273 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
275 2009-06-02 Paul Smith <psmith@gnu.org>
277 * configure.in: Check for fileno()
278 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
279 for the makefile file so invocations of $(shell ...) don't inherit it.
280 Fixes Savannah bug #24277.
282 2009-06-01 Paul Smith <psmith@gnu.org>
284 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
285 expansion was handled incorrectly. Rework the default goal
286 handling to save the variable only. Remove default_goal_file and
288 * read.c (eval): Check default_goal_var, not default_goal_name.
289 * read.c (record_target_var): Don't check default_goal_file here.
291 2009-05-31 Paul Smith <psmith@gnu.org>
293 * main.c (main): Expand the .DEFAULT_GOAL variable before using
294 it, and if the multi_glob() returns nothing (say it expanded to
295 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
297 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
298 $(and ..) to the reference. Fixes Savannah bug #25694.
300 * make.1: Be clear that some recipes will be executed even with -n.
301 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
303 * doc/make.texi (Override Directive): Make more clear how
304 overrides and appends interact.
305 Elucidates part of Savannah bug #26207.
307 * read.c (record_target_var): Don't reset the origin on
308 target-specific variables; try_variable_definition() will handle
309 this correctly. Fixes Savannah bug #26207.
311 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
312 Fixes Savannah bug #25712.
314 * implicit.c (pattern_search): Keep a pointer to the beginning of
315 the filename and save that instead of the constructed pointer.
316 Fixes Savannah bug #26593.
317 Patch by Mark Seaborn <mrs@mythic-beasts.com>
319 2009-05-30 Paul Smith <psmith@gnu.org>
321 * doc/make.texi (Multi-Line): Add a description of the new abilities
322 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
323 "command sequence" vs. "recipe" syntax.
324 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
325 after a define, to create variables with those flavors.
327 2009-05-25 Paul Smith <psmith@gnu.org>
329 Reworked the parser for variable assignments to allow multiple
330 modifiers, and in any order. Also allows variable and
331 prerequisites to be modifier names ('export', 'private', etc.)
333 * NEWS: Add notes about user-visible changes.
335 * read.c (struct vmodifiers): Remember what modifiers were seen.
336 (parse_var_assignment): New function to parse variable assignments.
337 (eval): Call the new function. Handle variable assignments earlier.
339 * variable.c (parse_variable_definition): Only parse; don't create var.
340 (assign_variable_definition): Call parse, then create the var.
342 2009-05-24 Paul Smith <psmith@gnu.org>
344 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
345 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.

349 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
350 Fixes Savannah bug #25412.
352 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
353 prototype for xmalloc.
354 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
355 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
356 Loop over an array of extensions, instead of duplicating the same
357 code inline. Use SearchPath followed by CreateFile, instead of
358 the obsolete OpenFile. Fixes Savannah bug #17277.
359 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
360 to `find_file'. Fixes Savannah bug #25662.
362 2009-03-07 Eli Zaretskii <eliz@gnu.org>
364 * function.c (func_shell): Don't close pipedes[1] if it is -1.
365 Fixes Savannah bug #20495.
367 2009-02-28 Ralf Wildenhues <address@hidden>
369 * doc/make.texi (Instead of Execution): Document interaction of
370 -t with phony targets.
372 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
374 Introduce a new keyword "private" which applies to target-specific
375 variables and prevents their values from being inherited.
377 * variable.h (struct variable): Add private_var flag to each variable.
378 Add a flag to specify which list entry switches to the parent target.

413 * README.W32.template: Remove obsolete text about non-support for
414 -jN without Unixy shell. Remove obsolete text about not supplying
415 Visual Studio project files (we do supply them). Modify text to
416 prefer GCC builds to MSC builds.
418 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
420 * doc/make.texi (Empty Targets): Fix typo.

437 2007-12-22 Eli Zaretskii <eliz@gnu.org>
439 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
441 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
442 (TEXINFOS): Value changed to `doc/make.texi'.
443 (.SUFFIXES): Use .texi instead of .texinfo.
444 (make.info, make.dvi): Depend on doc/make.texi.
445 (.texi.info): New target, instead of ".texinfo.info". Change -I
446 switch to $(MAKEINFO) to look in doc/. Use --no-split.
447 (.texi): New target, instead of ".texinfo". Change -I switch to
448 $(MAKEINFO) to look in doc/. Use --no-split.
449 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
450 switch to $(MAKEINFO) to look in doc/.
451 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

454 (html, make_1.html): New targets.
455 (.PHONY): Add "html".
456 (.SUFFIXES): Add .html.
458 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
460 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
461 HAVE_DECL_SYS_SIGLIST.
463 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
464 build does not use child_execute_job.
466 * variable.c (define_automatic_variables) [__MSDOS__]: Always
467 export the SHELL environment variable to the child.
469 2007-12-22 Eli Zaretskii <eliz@gnu.org>
471 * config.h.W32: Include sys/types.h.
472 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

478 2007-11-04 Paul Smith <psmith@gnu.org>
480 * doc/make.texi: Convert references to "commands", "command
481 lines", and "command script" to "recipe".

488 * remake.c (f_mtime): Print time difference values between 100 and
489 ULONG_MAX in fixed-point notation rather than in exponention notation.
491 2007-10-12 Eli Zaretskii <eliz@gnu.org>
493 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
494 a more complex value than a simple shell: if it's not a default
495 shell now then expand it and see if is a default shell then.
497 2007-10-10 Eli Zaretskii <eliz@gnu.org>
499 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
500 pathnames, with const strings.
501 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
502 from the template (used for building from CVS, not a dist).
504 2007-10-10 Paul Smith <psmith@gnu.org>
506 * make.h: Add a prototype for w32_kill() (change suggested by
507 Yongwei Wu <wuyongwei@gmail.com>).
509 2007-09-21 Eli Zaretskii <eliz@gnu.org>
511 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
514 2007-09-12 Paul Smith <psmith@gnu.org>
516 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
517 Provided by Diego Biurrun <diego@biurrun.de>
518 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
519 Provided by Diego Biurrun <diego@biurrun.de>
521 2007-09-11 Paul Smith <psmith@gnu.org>
523 * doc/make.texi (Special Variables): Moved this into the "How to
524 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

526 "Special Variables" section.
527 (Rule Introduction): Reference .RECIPEPREFIX.
528 (Simple Makefile): Ditto.
529 (Rule Syntax): Ditto.
530 (Command Syntax): Ditto.

553 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
555 2007-08-15 Paul Smith <psmith@gnu.org>

623 2007-05-08 Paul Smith <psmith@gnu.org>
625 Fix Savannah bug #19656:
627 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
629 * make.h: Change all case-insensitive string compares to use
630 strcasecmp() (from POSIX). If we don't have that but do have one
631 of the others, define strcasecmp to be one of those instead. If
632 we don't have any, declare a prototype for our own version.
634 * misc.c (strcasecmp): Use this if we can't find any native
635 case-insensitive string comparison function.
636 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
637 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
639 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
640 strcasecmp() instead of stricmp().
641 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
642 instead of strcmpi().
643 * acinclude.m4: Remove the strcasecmp() check from here.
645 2007-03-21 Paul Smith <psmith@gnu.org>
647 * configure.in: Don't turn on case-insensitive file system support
648 if --disable-... is given. Fixes Savannah bug #19348.
650 2007-03-19 Paul Smith <psmith@gnu.org>
652 * ALL: Use the strcache for all file name strings, or other
653 strings which we will never free. The goal is to save memory by
654 avoiding duplicate copies of strings. However, at the moment this
655 doesn't save much memory in most situations: due to secondary
656 expansion we actually save prerequisite lists twice (once before
657 the secondary expansion, and then again after it's been parsed
658 into individual file names in the dep list). We will resolve this
659 in a future change, by doing the parsing up-front for targets
660 where secondary expansion is not set.
662 Moving things into the strcache also allows us to use const
663 pointers in many more places.
665 2007-01-03 Paul Smith <psmith@gnu.org>
667 * make.h (ENULLLOOP): Reset errno after each failed invocation of
668 the function, not just the first. Fixes Savannah bug #18680.
670 2006-11-18 Paul Smith <psmith@gnu.org>
672 * strcache.c (strcache_add_len): Don't allocate a new buffer
673 unless the string is not already nil-terminated. Technically this
674 is a violation of the standard, since we may be passed an array
675 that is not long enough to test one past. However, in make this
676 is never true since we only use nil-terminated strings or
679 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
681 * main.c: New global cmd_prefix, defaults to '\t'.
682 * job.c (construct_command_argv_internal): Use cmd_prefix instead
686 (dir_contents_file_exists_p): Check for an error return from
687 readdir(), just in case.
689 * commands.c: Constified.
690 * default.c: Constified.
691 * expand.c: Constified.
692 * function.c: Partial constification.
693 * variable.c: Partial constification.

702 backslashes and drive letters as absolute.
704 2006-10-22 Paul Smith <psmith@gnu.org>

708 2006-10-21 Paul Smith <psmith@gnu.org>
711 * arscan.c: Constified.
713 2006-09-30 Paul Smith <psmith@gnu.org>
715 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
716 point to lastword since the example was updated.
717 Fixes Savannah bug #16304.
718 (Secondary Expansion): Correct example description.
719 Fixes Savannah bug #16468.

721 variable references or function calls.

724 Fixes Savannah bug #17701.
725 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

776 that don't have extended grep.
777 (cvsclean): Use $(PERL) instead of perl.

911 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
912 listed non-existent files as changed. Turns out there's a bug in
913 the Linux kernel builds which means that this change causes
914 everything to rebuild every time. We will re-introduce this fix
915 in the next release, to give them time to fix their build system.
916 Fixes Savannah bug #16002.

937 string values to avoid memory leaks.
939 * expand.c (recursively_expand_for_file): Only set reading_file to
940 an initialized value.
942 * implicit.c (pattern_search): We need to make a copy of the stem

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

959 prevent compiler warnings.
961 2006-02-18 Eli Zaretskii <eliz@gnu.org>

971 circularities in the linked list, if global_setlist->next in one
972 list gets set to point to another list which also ends in

976 2006-02-15 Paul D. Smith <psmith@gnu.org>
978 Fix for Savannah bug #106.

981 expanding. If no variable is being expanded, it's the same as
983 * make.h (expanding_var): Declare it.
984 * expand.c (recursively_expand_for_file): Set expanding_var to the
985 current variable we're expanding, unless there's no file info in

1003 an impossible file, free it.
1004 * variable.c (free_variable_set): New function.
1005 * variable.h: Declare it.
1007 * read.c (read_all_makefiles): Makefile names are kept in the

1012 archive support is enabled.

1027 A new internal capability: the string cache is a read-only cache
1028 of strings, with a hash table interface for fast lookup. Nothing
1029 in the cache will ever be freed, so there's no need for reference
1030 counting, etc. This is the beginning of a full solution for
1031 Savannah bug #15182, but for now we only store makefile names here.
1033 * strcache.c: New file. Implement a read-only string cache.
1034 * make.h: Add prototypes for new functions.

1042 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1043 directory time stamp didn't change, except on FAT filesystems.

1080 * README.cvs: Updates for building from CVS.
1082 2006-02-05 Paul D. Smith <psmith@gnu.org>
1084 * file.c (enter_file): Keep track of the last double_colon entry,
1085 to avoid walking the list every time we want to add a new one.
1086 Fixes Savannah bug #15533.
1087 * filedef.h (struct file): Add a new LAST pointer.
1089 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1090 the comparison. For 64-bits systems the result of the subtraction
1091 might not fit into an int. Use comparison instead.
1092 Fixes Savannah bug #15534.
1094 * doc/make.texi: Update the chapter on writing commands to reflect
1095 the changes made in 3.81 for backslash/newline and SHELL handling.
1097 2006-02-01 Paul D. Smith <psmith@gnu.org>
1099 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1100 variable st is not used when it's not initialized.
1101 Patch from Eli Zaretskii <eliz@gnu.org>.
1103 2006-01-31 Paul D. Smith <psmith@gnu.org>
1105 * README.W32.template: Applied patch #4785 from

1113 * prepare_w32.bat: Remove this file from the distribution.
1115 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1117 * remake.c (update_goal_chain): Set g->changed instead of
1118 incrementing it, as it is only 8-bit wide, and could overflow if
1119 many commands got started in update_file.
1121 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1123 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1124 MAXIMUM_WAIT_OBJECTS.
1125 (process_wait_for_any_private): Change dimension of handles[]
1126 array to MAXIMUM_WAIT_OBJECTS.
1127 (process_used_slots): New function.
1128 (process_register): Don't register more processes than the
1129 available number of slots.
1130 (process_easy): Don't start new processes if all slots are used up.
1132 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1133 are already more children than sub_proc.c can handle, behave as if
1134 the load were too high.
1135 (start_job_command): Fix a typo in error message when process_easy
1138 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1140 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1141 the shell is not sh.exe.
1143 * job.c (create_batch_file): Renamed from create_batch_filename;
1144 all callers changed. Don't close the temporary file; return its
1145 file descriptor instead. New arg FD allows to return the file
1147 (construct_command_argv_internal): Use _fdopen instead of fopen to
1148 open the batch file.
1150 2006-01-04 Paul D. Smith <psmith@gnu.org>
1152 * readme.vms: Updates for case-insensitive VMS file systems from
1153 Hartmut Becker <Hartmut.Becker@hp.com>.
1154 * dir.c (vms_hash): Ditto.
1155 * vmsify.c (copyto): Ditto.
1156 * vmsfunctions.c (readdir): Ditto.
1158 * make.1: Add a section on the exit codes for make.
1160 * doc/make.texi: A number of minor updates to the documentation.
1162 2006-01-03 Paul D. Smith <psmith@gnu.org>
1164 * remake.c (update_file_1): Mark a prerequisite changed if it
1167 * read.c (eval): Be sure to strip off trailing whitespace from the
1168 prerequisites list properly. Also, initialize all fields in
1169 struct dep when creating a new one.
1171 2005-12-28 Paul D. Smith <psmith@gnu.org>
1173 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1174 disable warnings for MSC.
1175 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1177 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1179 * doc/make.texi (Execution): Add a footnote about changes in
1180 handling of backslash-newline sequences. Mention the differences
1181 on MS-DOS and MS-Windows.
1183 * NEWS: More details about building the MinGW port and a pointer
1184 to README.W32. Fix the section name that describes the new
1185 backward-incompatible processing of backslash-newline sequences.
1186 The special processing of SHELL set to "cmd" is only relevant to
1187 MS-Windows, not MS-DOS.
1189 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1191 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1192 to DWORD, to avoid compiler warnings.
1193 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1194 use %ld in format, to avoid compiler warnings.
1196 * doc/make.texi (Special Targets): Fix a typo.
1197 (Appending): Fix cross-reference to Setting.
1198 (Special Variables, Secondary Expansion, File Name Functions)
1199 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1200 periods after a sentence.
1201 (Execution): Add @: after "e.g.".
1202 (Environment): Fix punctuation.
1203 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1204 (Shell Function, Target-specific): Add @: after "vs."
1206 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1208 * read.c (record_target_var): Initialize variable's export field
1209 with v_default instead of leaving it "initialized" by whatever
1210 garbage happened to be on the heap.
1212 2005-12-12 Paul D. Smith <psmith@gnu.org>
1214 * make.1: Fix some display errors and document all existing options.
1215 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1217 2005-12-11 Paul D. Smith <psmith@gnu.org>
1219 * implicit.c (pattern_search): If 2nd expansion is not set for
1220 this implicit rule, replace the pattern with the stem directly,
1221 and don't re-expand the variable list. Along with the other
1222 .SECONDEXPANSION changes below, fixes bug #13781.
1224 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1226 * implicit.c (pattern_search): Mark other files that this rule
1227 builds as targets so that they are not treated as intermediates
1228 by the pattern rule search algorithm. Fixes bug #13022.
1230 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1232 * remake.c (notice_finished_file): Propagate the change of
1233 modification time to all the double-colon entries only if
1234 it is the last one to be updated. Fixes bug #14334.
1236 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1238 * function.c (func_flavor): Implement the flavor function which
1239 returns the flavor of a variable.
1240 * doc/make.texi (Functions for Transforming Text): Document it.
1241 * NEWS: Add it to the list of new functions.
1243 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1245 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1247 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1248 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1250 2005-10-26 Paul Smith <psmith@gnu.org>
1252 * read.c (record_files): Don't set deps flags if there are no deps.
1253 * maintMakefile: We only need to build the templates when we are
1254 creating a distribution, so don't do it for "all".
1256 2005-10-24 Paul D. Smith <psmith@gnu.org>
1258 Make secondary expansion optional: its enabled by declaring the
1259 special target .SECONDEXPANSION.
1261 * NEWS: Update information on second expansion capabilities.
1262 * doc/make.texi (Secondary Expansion): Document the
1263 .SECONDEXPANSION special target and its behavior.
1264 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1265 prerequisite list was found in a static pattern rule.
1266 (free_dep_chain): Declare a prototype.
1267 * file.c (parse_prereqs): New function: break out some complexity
1269 (expand_deps): If we aren't doing second expansion, replace % with
1270 the stem for static pattern rules. Call the new function.
1271 * filedef.h (parse_prereqs): Declare a prototype.
1272 * implicit.c (pattern_search): Initialize the new staticpattern
1274 * main.c (second_expansion): Declare a global variable to remember
1275 if the special target has been seen. Initialize the new
1276 staticpattern field for prerequisites.
1277 * make.h: Extern for second_expansion.
1278 * misc.c (free_dep_chain): New function: frees a struct dep list.
1279 * read.c (read_all_makefiles): Initialize the staticpattern field.
1280 (eval_makefile): Ditto.
1281 (record_files): Check for the .SECONDEXPANSION target and set
1282 second_expansion global if it's found.
1283 Use the new free_dep_chain() instead of doing it by hand.
1284 Set the staticpattern field for prereqs of static pattern targets.
1286 2005-10-16 Paul D. Smith <psmith@gnu.org>
1288 * main.c (main): Set CURDIR to be a file variable instead of a
1289 default, so that values of CURDIR inherited from the environment
1290 won't override the make value.
1292 2005-09-26 Paul D. Smith <psmith@gnu.org>
1294 * job.c (construct_command_argv_internal): If the line is empty
1295 remember to free the temporary argv strings.
1298 2005-09-16 Paul D. Smith <psmith@gnu.org>
1300 * job.c (start_job_command): The noerror flag is a boolean (single
1301 bit); set it appropriately.
1302 Reported by Mark Eichin <eichin@metacarta.com>
1304 2005-08-29 Paul D. Smith <psmith@gnu.org>
1306 * function.c (func_error): On Windows, output from $(info ...)
1307 seems to come in the wrong order. Try to force it with fflush().
1309 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1311 * read.c (record_files): Move code that sets stem for static
1312 pattern rules out of the if (!two_colon) condition so it is
1313 also executed for two-colon rules. Fixes Savannah bug #13881.
1315 2005-08-08 Paul D. Smith <psmith@gnu.org>
1317 * make.h: Don't test that __STDC__ is non-0. Some compilers
1318 (Windows for example) set it to 0 to denote "ISO C + extensions".
1321 2005-08-07 Paul D. Smith <psmith@gnu.org>
1323 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1324 conditional (slightly different version of a fix from Eli).
1326 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1327 If make is running in parallel without -k and two jobs die in a
1328 row, but not too close to each other, then make will quit without
1329 waiting for the rest of the jobs to die.
1331 * main.c (die): Don't reset err before calling reap_children() the
1332 second time: we still want it to be in the error condition.
1333 * job.c (reap_children): Use a static variable, rather than err,
1334 to control whether or not the error message should be printed.
1336 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1338 * w32/subproc/sub_proc.c: Include signal.h.
1339 (process_pipe_io, process_file_io): Pass a pointer to a local
1340 DWORD variable to GetExitCodeProcess. If the exit code is
1341 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1343 * job.c [WINDOWS32]: Include windows.h.
1344 (main_thread) [WINDOWS32]: New global variable.
1345 (reap_children) [WINDOWS32]: Get the handle for the main thread
1346 and store it in main_thread.
1348 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1349 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1350 doing anything else. When we are done, close the main thread
1351 handle and exit with status 130.
1353 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1355 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1358 * main.c (find_and_set_default_shell): If found a DOSish shell,
1359 set sh_found and the value of default_shell, and report the
1360 findings in debug mode.
1362 * job.c (construct_command_argv_internal): Check unixy_shell, not
1363 no_default_sh_exe, to decide whether to use Unixy or DOSish
1366 * README.W32: Update with info about the MinGW build.
1368 * build_w32.bat: Support MinGW.
1370 * w32/subproc/build.bat: Likewise.
1372 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1373 printing DWORD args.
1375 * function.c (windows32_openpipe): Fix format strings for printing
1378 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1380 (start_job_command): Fix format string for printing the result of
1382 (start_job_command) [WINDOWS32]: Do not define.
1383 (exec_command): Fix format string for printing HANDLE args.
1385 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1386 to avoid compiler warnings.
1387 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1388 (Note: some of these fixes were submitted independently by J. Grant)
1390 2005-07-30 J. Grant <jg@jguk.org>
1392 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1393 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1394 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1396 2005-07-15 Paul Smith <psmith@gnu.org>
1398 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1399 we don't have a POSIX shell, then revert to the old
1400 backslash-newline behavior (where they are stripped).
1403 2005-07-08 Paul D. Smith <psmith@gnu.org>
1405 * config.h.W32.template: Reorder to match the standard config.h,
1406 for easier comparisons.
1407 From J. Grant <jg@jguk.org>
1409 * maintMakefile: Remove .dep_segment before overwriting it, in
1410 case it's not writable or noclobber is set.
1411 * expand.c (variable_expand_string): Cast result of pointer
1412 arithmetic to avoid a warning.
1413 * main.c (switches): Add full-fledged final initializer.
1415 2005-07-06 Paul D. Smith <psmith@gnu.org>
1417 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1418 * signame.c (strsignal): If we found _sys_siglist[] or
1419 __sys_siglist[] use those instead of sys_siglist[].
1420 From Albert Chin <china@thewrittenword.com>
1422 2005-07-04 Paul D. Smith <psmith@gnu.org>
1424 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1425 globfree(); set up to use the GNU versions.
1426 From Martin Zinser <zinser@zinser.no-ip.info>
1428 2005-07-03 Paul D. Smith <psmith@gnu.org>
1430 From J. Grant <jg@jguk.org>:
1432 * README.W32.template: Update the Windows and tested MSVC versions.
1433 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1434 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1435 * build_w32.bat: Ditto.
1436 * w32/subproc/build.bat: Ditto.
1438 2005-06-28 Paul D. Smith <psmith@gnu.org>
1440 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1441 declaration was checked but not present.
1443 2005-06-27 Paul D. Smith <psmith@gnu.org>
1445 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1446 to unsigned long. Fixes Savannah bug #13550.
1448 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1449 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1450 Fixes Savannah bug #13551.
1452 2005-06-26 Paul D. Smith <psmith@gnu.org>
1454 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1455 it if ANSI_STRING is not set.
1457 2005-06-25 Paul D. Smith <psmith@gnu.org>
1459 * read.c (eval): If no filenames are passed to any of the
1460 "include" variants, don't print an error.
1461 * doc/make.texi (Include): Document this.
1462 Fixes Savannah bug #1761.
1464 * job.c (construct_command_argv_internal): Sanitize handling of
1465 backslash/newline pairs according to POSIX: that is, keep the
1466 backslash-newline in the command script, but remove a following
1467 TAB character, if present. In the fast path, make sure that the
1468 behavior matches what the shell would do both inside and outside
1469 of quotes. In the slow path, quote the backslash and put a
1470 literal newline in the string.
1471 Fixes Savannah bug #1332.
1472 * doc/make.texi (Execution): Document the new behavior and give
1474 * NEWS: Make a note of the new behavior.
1476 * make.h [WINDOWS32]: #include <direct.h>.
1477 Fixes Savannah bug #13478.
1479 * remake.c (name_mtime): If the stat() of a file fails and the -L
1480 option was given and the file is a symlink, take the best mtime of
1481 the symlink we can get as the mtime of the file and don't fail.
1482 Fixes Savannah bug #13280.
1484 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1485 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1486 inside a variable reference. Make this function static as it's
1488 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1489 parsing an unexpanded line looking for semicolons.
1490 Fixes Savannah bug #1454.
1491 * misc.c (remove_comments): Move this to read.c and make it static
1492 as it's only used there. Call find_char_unquote() with new arg.
1493 * make.h: Remove prototypes for find_char_unquote() and
1494 remove_comments() since they're static now.
1496 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1497 its export flag and obtain its value. When we need to re-exec,
1498 increment the value and add it into the environment.
1499 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1500 * NEWS: Mention MAKE_RESTARTS.
1501 * main.c (always_make_set): New variable. Change the -B option to
1502 set this one instead.
1503 (main): When checking makefiles, only set always_make_flag if
1504 always_make_set is set AND the restarts flag is 0. When building
1505 normal targets, set it IFF always_make_set is set.
1506 (main): Avoid infinite recursion with -W, too: only set what-if
1507 files to NEW before we check makefiles if we've never restarted
1508 before. If we have restarted, set what-if files to NEW _after_ we
1510 Fixes Savannah bug #7566:
1512 2005-06-17 Paul D. Smith <psmith@gnu.org>
1514 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1515 in the prerequisites list.
1517 2005-06-12 Paul D. Smith <psmith@gnu.org>
1519 Fix Savannah bug # 1328.
1521 * configure.in: Check for atexit().
1522 * misc.c (close_stdout): Test stdout to see if writes to it have
1523 failed. If so, be sure to exit with a non-0 error code. Based on
1524 code found in gnulib.
1525 * make.h: Prototype.
1526 * main.c (main): Install close_stdout() with atexit().
1528 2005-06-10 Paul D. Smith <psmith@gnu.org>
1530 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1532 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1533 headers; make vmsWaitForChildren() static; extern vmsify().
1534 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1535 Don't create child_execute_job() here (it's in vmsjobs.c).
1536 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1538 2005-06-09 Paul D. Smith <psmith@gnu.org>
1540 * variable.c (push_new_variable_scope): File variables point
1541 directly to the global_setlist variable. So, inserting a new
1542 scope in front of that has no effect on those variables: they
1543 don't go through current_variable_set_list. If we're pushing a
1544 scope and the current scope is global, push it "the other way" so
1545 that the new setlist is in the global_setlist variable, and
1546 next points to a new setlist with the global variable set.
1547 (pop_variable_scope): Properly undo a push with the new
1549 Fixes Savannah bug #11913.
1551 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1553 * job.c (reap_children): Don't die of the command failed but
1554 the dontcare flag is set. Fixes Savannah bug #13216.
1556 * implicit.c (pattern_search): When creating a target from
1557 an implicit rule match, lookup pattern target and set precious
1558 flag in a newly created target. Fixes Savannah bug #13218.
1560 2005-05-13 Paul D. Smith <psmith@gnu.org>
1562 Implement "if... else if... endif" syntax.
1564 * read.c (eval): Push all checks for conditional words ("ifeq",
1565 "else", etc.) down into the conditional_line() function.
1566 (conditional_line): Rework to allow "else if..." clause. New
1567 return value -2 for lines which are not conditionals. The
1568 ignoring flag can now also be 2, which means "already parsed a
1569 true branch". If that value is seen no other branch of this
1570 conditional can be considered true. In the else parsing if there
1571 is extra text after the else, invoke conditional_line()
1572 recursively to see if it's another conditional. If not, it's an
1573 error. If so, raise the conditional value to this level instead
1574 of creating a new conditional nesting level. Special check for
1575 "else" and "endif", which aren't allowed on the "else" line.
1576 * doc/make.texi (Conditional Syntax): Document the new syntax.
1578 2005-05-09 Paul D. Smith <psmith@gnu.org>
1580 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1581 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1582 recurses to the w32 directory, even on non-Windows systems. Use
1583 the method suggested in the automake manual.
1584 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1585 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1587 2005-05-07 Paul D. Smith <psmith@gnu.org>
1589 * main.c (die): If we're dying with a fatal error (not that a
1590 command has failed), write back any leftover tokens before we go.
1592 * job.c (set_child_handler_action_flags): If there are jobs
1593 waiting for the load to go down, set an alarm to go off in 1
1594 second. This allows us to wake up from a potentially long-lasting
1595 read() and start a new job if the load has gone down. Turn it off
1597 (job_noop): Dummy signal handler function.
1598 (new_job): Invoke it with the new semantics.
1600 * docs/make.texi: Document secondary expansion. Various cleanups
1603 2005-05-03 Paul D. Smith <psmith@gnu.org>
1605 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1606 the targets which are to ultimately be made are called "goals";
1607 see the GNU make manual. Also, MAKECMDGOALS, etc.
1609 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1610 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1611 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1613 2005-05-02 Paul D. Smith <psmith@gnu.org>
1615 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1616 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1617 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1618 functions to vmsjobs.c. #include it into jobs.c.
1620 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1621 jobserver tokens. I found that this happens when an exported
1622 recursive variable contains a $(shell ...) function reference: in
1623 this situation we could "forget" to write back a token.
1625 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1626 we have. It's not reliable to depend on the number of children in
1627 our linked list so keep a separate count.
1628 (new_job): Check jobserver_tokens rather than children &&
1629 waiting_jobs. Increment jobserver_tokens when we get one.
1630 (free_child): If jobserver_tokens is 0, internal error. If it's
1631 >1, write a token back to the jobserver pipe (we don't write a
1632 token for the "free" job). Decrement jobserver_tokens.
1634 * main.c: Add variable master_job_slots.
1635 (main): Set it to hold the number of jobs requested if we're the
1636 master process, when using the jobserver.
1637 (die): Sanity checks: first test jobserver_tokens to make sure
1638 this process isn't holding any tokens we didn't write back.
1639 Second, if master_job_slots is set count the tokens left in the
1640 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1642 2005-04-24 Paul D. Smith <psmith@gnu.org>
1644 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1645 with -l# can lose jobserver tokens, because waiting jobs are not
1646 consulted properly when checking for the "free" token.
1648 * job.c (free_child): Count waiting_jobs as having tokens.
1649 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1650 handle jobs waiting for the load to drop.
1652 2005-04-23 Paul D. Smith <psmith@gnu.org>
1654 * main.c (main): Be careful to not core if a variable setting in
1655 the environment doesn't contain an '='. This is illegal but can
1656 happen in broken setups.
1657 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1659 2005-04-12 Paul D. Smith <psmith@gnu.org>
1661 The second expansion feature causes significant slowdown. Timing
1662 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1663 read the makefile before the feature, to 11+s to do the same
1664 operations after the feature. Additionally, memory usage
1665 increased drastically. To fix this I added some intelligence that
1666 avoids the overhead of the second expansion unless it's required.
1668 * dep.h: Add a new boolean field, need_2nd_expansion.
1670 * read.c (eval): When creating the struct dep for the target,
1671 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1672 (record_files): If there's a "%" in a static pattern rule, it gets
1673 converted to "$*" so set need_2nd_expansion to 1.
1675 * file.c (expand_deps): Rework to be more efficient. Only perform
1676 initialize_file_variables(), set_file_variables(), and
1677 variable_expand_for_file() if the need_2nd_expansion is set.
1679 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1680 (pattern_search): Ditto.
1681 * main.c (handle_non_switch_argument): Ditto.
1683 * read.c (read_all_makefiles): Ditto.
1684 (eval_makefile): Ditto.
1686 2005-04-07 Paul D. Smith <psmith@gnu.org>
1688 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1689 * variable.c (sync_Path_environment): Ditto.
1690 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1692 * main.c (main): Define the .FEATURES variable.
1693 * NEWS: Announce .FEATURES.
1694 * doc/make.texi (Special Variables): Document .FEATURES.
1696 * remake.c (check_dep): If a file is .PHONY, update it even if
1697 it's marked intermediate. Fixes Savannah bug #12331.
1699 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1701 * file.c (expand_deps): Factor out the second expansion and
1702 prerequisite line parsing logic from snap_deps().
1704 * file.c (snap_deps): Use expand_deps(). Expand and parse
1705 prerequisites of the .SUFFIXES special target first. Fixes
1706 Savannah bug #12320.
1708 2005-03-13 Paul D. Smith <psmith@gnu.org>
1710 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1713 2005-03-11 Paul D. Smith <psmith@gnu.org>
1715 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1716 available, not undefined (from Earnie Boyd).
1718 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1720 * implicit.c (pattern_search): Mark an intermediate target as
1721 precious if it happened to be a prerequisite of some (other)
1722 target. Fixes Savannah bug #12267.
1724 2005-03-09 Paul D. Smith <psmith@gnu.org>
1726 * read.c (eval_makefile): Add alloca(0).
1727 (eval_buffer): Ditto.
1729 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1731 * main.c (main): Use o_file instead of o_default when defining
1732 the .DEFAULT_TARGET special variable.
1733 * read.c (eval): Use define_variable_global() instead of
1734 define_variable() when setting new value for the .DEFAULT_TARGET
1735 special variable. Fixes Savannah bug #12266.
1737 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1739 * imlicit.c (pattern_search): Mark files for which an implicit
1740 rule has been found as targets. Fixes Savannah bug #12202.
1742 2005-03-04 Paul D. Smith <psmith@gnu.org>
1745 * doc/make.texi (Automatic Variables): Document $|.
1747 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1749 * read.c (record_files): Instead of substituting % with
1750 actual stem value in dependency list replace it with $*.
1751 This fixes stem triple expansion bug.
1753 * implicit.c (pattern_search): Copy stem to a separate
1754 buffer and make it a properly terminated string. Assign
1755 this buffer instead of STEM (which is not terminated) to
1756 f->stem. Instead of substituting % with actual stem value
1757 in dependency list replace it with $*. This fixes stem
1758 triple expansion bug.
1760 2005-03-01 Paul D. Smith <psmith@gnu.org>
1762 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1763 on Windows, as it takes a handle not a pid. Just exit.
1764 Fix from patch #3679, provided by Alessandro Vesely.
1766 * configure.in: Update check for sys_siglist[] from autoconf manual.
1767 * signame.c (strsignal): Update to use the new autoconf macro.
1769 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1771 * read.c (record_files): Add a check for the list of prerequisites
1772 of a static pattern rule being empty. Fixes Savannah bug #12180.
1774 2005-02-28 Paul D. Smith <psmith@gnu.org>
1776 * doc/make.texi (Text Functions): Update docs to allow the end
1777 ordinal for $(wordlist ...) to be 0.
1778 * function.c (func_wordlist): Fail if the start ordinal for
1779 $(wordlist ...) is <1. Matches documentation.
1780 Resolves Savannah support request #103195.
1782 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1783 previously we were stopping when !-q, exactly the opposite. This
1784 has been wrong since version 1.34, in 1994!
1785 (update_file): If we got an error don't break out to run more
1786 double-colon rules: just return immediately.
1787 Fixes Savannah bug #7144.
1789 2005-02-27 Paul D. Smith <psmith@gnu.org>
1791 * misc.c (end_of_token): Make argument const.
1792 * make.h: Update prototype.
1794 * function.c (abspath, func_realpath, func_abspath): Use
1795 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1796 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1797 * read.c (record_files): Ditto.
1798 * variable.c (do_variable_definition): Ditto.
1800 * function.c (func_error): Create a new function $(info ...) that
1801 simply prints the message to stdout with no extras.
1802 (function_table_init): Add new function to the table.
1803 * NEWS: Add $(info ...) reference.
1804 * doc/make.texi (Make Control Functions): Document it.
1806 New feature: if the system supports symbolic links, and the user
1807 provides the -L/--check-symlink-time flag, then use the latest
1808 mtime between the symlink(s) and the target file.
1810 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1811 readlink(). If both are available, define MAKE_SYMLINKS.
1812 * main.c: New variable: check_symlink_flag.
1813 (usage): Add a line for -L/--check-symlink-times to the help string.
1814 (switches): Add -L/--check-symlink-times command line argument.
1815 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1816 print a warning and disable it again.
1817 * make.h: Declare check_symlink_flag.
1818 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1819 if the file is a symlink then check each link in the chain and
1820 choose the NEWEST mtime we find as the mtime for the file. The
1821 newest mtime might be the file itself!
1822 * NEWS: Add information about this new feature.
1823 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1825 Avoid core dumps described in Savannah bug # 12124:
1827 * file.c: New variable snapped_deps remember whether we've run
1829 (snap_deps): Set it.
1830 * filedef.h: Extern it.
1831 * read.c (record_files): Check snapped_deps; if it's set then
1832 we're trying to eval a new target/prerequisite relationship from
1833 within a command script, which we don't support. Fatal.
1835 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1837 Implementation of the .DEFAULT_TARGET special variable.
1839 * read.c (eval): If necessary, update default_target_name when
1841 * read.c (record_files): Update default_target_file if
1842 default_target_name has changed.
1843 * main.c (default_target_name): Define.
1844 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1845 default_target_name is set use default_target_file as a root
1847 * filedef.h (default_target_name): Declare.
1848 * dep.h (free_dep_chain):
1849 * misc.c (free_dep_chain): Change to operate on struct nameseq
1850 and change name to free_ns_chain.
1851 * file.c (snap_deps): Update to use free_ns_chain.
1853 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1855 Implementation of the second expansion in explicit rules,
1856 static pattern rules and implicit rules.
1858 * read.c (eval): Refrain from chopping up rule's dependencies.
1859 Store them in a struct dep as a single dependency line. Remove
1860 the code that implements SySV-style automatic variables.
1862 * read.c (record_files): Adjust the code that handles static
1863 pattern rules to expand all percents instead of only the first
1864 one. Reverse the order in which dependencies are stored so that
1865 when the second expansion reverses them again they appear in
1866 the makefile order (with some exceptions, see comments in
1867 the code). Remove the code that implements SySV-style automatic
1870 * file.c (snap_deps): Implement the second expansion and chopping
1871 of dependency lines for explicit rules.
1873 * implicit.c (struct idep): Define an auxiliary data type to hold
1874 implicit rule's dependencies after stem substitution and
1877 * implicit.c (free_idep_chain): Implement.
1879 * implicit.c (get_next_word): Implement helper function for
1880 parsing implicit rule's dependency lines into words taking
1881 into account variable expansion requests. Used in the stem
1884 * implicit.c (pattern_search): Implement the second expansion
1885 for implicit rules. Also fixes bug #12091.
1887 * commands.h (set_file_variables): Declare.
1888 * commands.c (set_file_variables): Remove static specifier.
1890 * dep.h (free_dep_chain): Declare.
1891 * misc.c (free_dep_chain): Implement.
1893 * variable.h (variable_expand_for_file): Declare.
1894 * expand.c (variable_expand_for_file): Remove static specifier.
1896 * make.h (strip_whitespace): Declare.
1897 * function.c (strip_whitespace): Remove static specifier.
1899 2005-02-26 Paul D. Smith <psmith@gnu.org>
1901 * main.c (main): Check for ferror() when reading makefiles from stdin.
1902 Apparently some shells in Windows don't close pipes properly and
1905 2005-02-24 Jonathan Grant <jg@jguk.org>
1907 * configure.in: Add MinGW configuration options, and extra w32 code
1909 * Makefile.am: Add MinGW configuration options, and extra w32 code
1911 * main.c: Determine correct program string (after last \ without .exe).
1912 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1914 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1915 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1916 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1917 environment support.
1919 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1921 * function.c (func_shell): When initializing error_prefix, check
1922 that reading file name is not null. This fixes long-standing
1923 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1925 2005-02-09 Paul D. Smith <psmith@gnu.org>
1927 * maintMakefile: Update the CVS download URL to simplify them.
1928 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1929 downloading the .texi files from Savannah now.
1931 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1933 * main.c (handle_non_switch_argument): Only add variables to
1934 command_variables if they're not already there: duplicate settings
1935 waste space and can be confusing to read.
1937 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1938 this header is never included by non-WINDOWS32 code, and it
1939 requires <config.h> to define which isn't always included first.
1941 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1942 testing MINGW32 versions.
1944 * main.c (log_working_directory): flush stdout to be sure the WD
1945 change is printed before any stderr messages show up.
1947 2005-02-01 Paul D. Smith <psmith@gnu.org>
1949 * maintMakefile (po_repo): Update the GNU translation site URL.
1951 2004-12-01 Paul D. Smith <psmith@gnu.org>
1953 * main.c (main): Change char* env_shell to struct variable shell_var.
1954 * variable.c (target_environment): Use new shell_var.
1956 2004-11-30 Paul D. Smith <psmith@gnu.org>
1958 * configure.in: The old way we avoided creating build.sh from
1959 build.sh.in before build.sh.in exists doesn't work anymore; we
1960 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1961 the help!). This also keeps automake from complaining.
1962 * Makefile.am (README): Add a dummy target so automake won't
1963 complain that this file doesn't exist when we checkout from CVS.
1964 * maintMakefile (.dep_segment): Rewrite this rule since newer
1965 versions of automake don't provide DEP_FILES.
1967 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1969 Implementation of `realpath' and `abspath' built-in functions.
1971 * configure.in: Check for realpath.
1972 * function.c (abspath): Return an absolute file name that does
1973 not contain any `.' or `..' components, nor repeated `/'.
1974 * function.c (func_abspath): For each name call abspath.
1975 * function.c (func_realpath): For each name call realpath
1976 from libc or delegate to abspath if realpath is not available.
1977 * doc/make.texi (Functions for File Names): Document new functions.
1978 * doc/make.texi (Quick Reference): Ditto.
1980 2004-11-28 Paul D. Smith <psmith@gnu.org>
1982 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1983 arguments. Fixes bug #10252.
1985 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1987 * main.c (main): Set SHELL to v_noexport by default. Remember the
1988 original environment setting of SHELL in the env_shell variable.
1989 * main.h: Export new env_shell variable.
1990 * variable.c (target_environment): If we find a v_noexport
1991 variable for SHELL, add a SHELL variable with the env_shell value.
1992 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1993 * doc/make.texi (Variables/Recursion): Ditto.
1995 2004-11-28 Paul D. Smith <psmith@gnu.org>
1997 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1998 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1999 Patch by Alessandro Vesely.
2001 2004-11-12 Paul D. Smith <psmith@gnu.org>
2003 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2004 the command line if it's inside a string.
2005 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2007 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2009 * function.c (func_lastword): New function: return last word
2010 from the list of words.
2011 * doc/make.texi: Document $(lastword ). Fix broken links in
2012 Quick Reference section.
2014 2004-10-06 Paul D. Smith <psmith@gnu.org>
2016 Apply patch from Alessandro Vesely, provided with bug # 9748.
2017 Fix use of tmpnam() to work with Borland C.
2019 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2020 construction of a temporary filename, and call new function
2021 create_batch_filename().
2022 (create_batch_filename) [WINDOWS32]: New function to create a
2025 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2027 * read.c (record_target_var): Expand simple pattern-specific
2029 * variable.c (initialize_file_variables): Do not expand simple
2030 pattern-specific variable.
2032 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2034 * remake.c (update_file_1): When rebuilding makefiles inherit
2035 dontcare flag from a target that triggered update.
2037 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2039 * variable.c (initialize_file_variables): Mark pattern-specific
2040 variable as a per-target and copy export status.
2042 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2044 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2046 * implicit.c (pattern_search): When considering an implicit rule's
2047 prerequisite check that it is actually a target rather then
2048 just an entry in the file hashtable.
2050 2004-09-21 Paul D. Smith <psmith@gnu.org>
2052 * read.c (readstring): Fix some logic errors in backslash handling.
2053 (eval): Remove some unnecessary processing in buffer handling.
2054 (record_target_var): Assert that parse_variable_definition() succeeded.
2055 Reported by: Markus Mauhart <qwe123@chello.at>.
2057 * misc.c: Removed the sindex() function. All instances of this
2058 function were trivially replaceable by the standard strstr()
2059 function, and that function will always have better (or certainly
2060 no worse) performance than the very simple-minded algorithm
2061 sindex() used. This can matter with complex makefiles.
2062 * make.h: Remove the prototype for sindex().
2063 * function.c (subst_expand): Convert sindex() call to strstr().
2064 This means we no longer need to track the TLEN value so remove that.
2065 (func_findstring): Convert sindex() to strstr().
2066 * commands.c (chop_commands): Convert sindex() calls to strstr().
2067 Suggested by: Markus Mauhart <qwe123@chello.at>.
2069 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2070 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2071 If SHELL is set to CMD.EXE then assume it's batch-mode and
2072 non-unixy. I wrote the code differently from the patch, though,
2073 to make it safer. This also resolves bug #9174.
2075 2004-09-20 Paul D. Smith <psmith@gnu.org>
2077 * expand.c (variable_expand_string): Modify to invoke
2078 patsubst_expand() instead of subst_expand(); the latter didn't
2079 handle suffix patterns correctly.
2080 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2081 was used only from variable_expand_string() and is no longer used
2083 (func_subst): Ditto, on call to subst_expand().
2084 (patsubst_expand): Require the percent pointers to point to the
2085 character after the %, not to the % itself.
2086 * read.c (record_files): New call criteria for patsubst_expand().
2087 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2088 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2090 2004-09-19 Paul D. Smith <psmith@gnu.org>
2092 * function.c (subst_expand): Fix a check in by_word: look for a
2093 previous blank if we're beyond the beginning of the string, not
2094 the beginning of the word.
2095 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2097 2004-05-16 Paul D. Smith <psmith@gnu.org>
2099 * remake.c (update_goal_chain): Change the argument specifying
2100 whether we're rebuilding makefiles to be a global variable,
2101 REBUILDING_MAKEFILES.
2102 (complain): Extract the code that complains about no rules to make
2103 a target into a separate function.
2104 (update_file_1): If we tried to rebuild a file during the makefile
2105 rebuild phase and it was dontcare, then no message was printed.
2106 If we then try to build the same file during the normal build,
2107 print a message this time.
2108 (remake_file): Don't complain about un-remake-able files when
2109 we're rebuilding makefiles.
2111 2004-05-11 Paul D. Smith <psmith@gnu.org>
2113 * job.c (construct_command_argv_internal): OS/2 patches from
2114 Andreas Buening <andreas.buening@nexgo.de>.
2116 2004-05-10 Paul D. Smith <psmith@gnu.org>
2118 * remake.c (update_file): Don't walk the double-colon chain unless
2119 this is a double-colon rule. Fix suggested by Boris Kolpackov
2120 <boris@kolpackov.net>.
2122 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2123 * readme.vms: New section describing OpenVMS support and issues.
2124 * default.c (default_variables): Add support for IA64.
2125 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2126 without some privilege aborts make with the error
2127 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2128 pressing Ctrl+Y and the input device is no terminal. The change
2129 catches this error and just continues.
2131 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2133 2004-04-25 Paul D. Smith <psmith@gnu.org>
2135 * commands.c (set_file_variables): Set $< properly in the face of
2136 order-only prerequisites.
2137 Patch from Boris Kolpackov <boris@kolpackov.net>
2139 2004-04-21 Bob Byrnes <byrnes@curl.com>
2141 * main.c (main): Notice failures to remake makefiles.
2143 2004-03-28 Paul D. Smith <psmith@gnu.org>
2145 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2147 * job.c: No default shell for RISC OS.
2148 (load_too_high): Hard-code the return to 1.
2149 (construct_command_argv_internal): No sh_chars or sh_cmds.
2150 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2152 2004-03-20 Paul D. Smith <psmith@gnu.org>
2154 * variable.c (do_variable_definition): Don't append from the
2155 global set if a previous non-appending target-specific variable
2156 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2159 * expand.c (reference_variable): Don't give up on variables with
2160 no value that have the target-specific append flag set: they might
2161 have a value after all. Reported by Oliver Schmidt
2162 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2163 <nikulin@dx1cmd.inp.nsk.su>.
2165 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2166 refer to absolute pathnames in directories that don't exist: some
2167 portion of the makefile could create those directories before we
2168 match the pattern. Fixes bugs #775 and #108.
2170 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2172 * main.c (main): Free makefile_mtimes if we have any.
2173 * README.W32.template: Update documentation for the current status
2174 of the MS-Windows port.
2175 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2176 environment variable is sometimes already defined which causes the
2178 * main.c (debug_signal_handler): Only define this function if
2179 SIGUSR1 is available.
2181 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2183 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2184 * README.OS2.template: Documentation updates.
2185 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2186 link line for safety.
2187 * maintMakefile (build.sh.in): Remove an extraneous ")".
2188 * job.c (child_execute_job): Close saved FDs.
2189 * job.c (exec_command) [OS/2]: exec_command(): If the command
2190 can't be exec'ed and if the shell is not Unix-sh, then try again
2191 with argv = { "cmd", "/c", ... }. Normally, this code is never
2192 reached for the cmd shell unless the command really doesn't exist.
2193 (construct_command_argv_internal) [OS/2]: The code for cmd
2194 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2195 The CMD builtin commands are case insensitive so use strcasecmp().
2197 2004-03-19 Paul D. Smith <psmith@gnu.org>
2199 * read.c (do_define): Re-order line counter increment so the count
2200 is accurate (we were losing one line per define). Reported by
2201 Dave Yost <Dave@Yost.com>.
2203 2004-03-06 Paul D. Smith <psmith@gnu.org>
2205 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2207 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2208 * misc.c (message,error,fatal): Ditto.
2209 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2210 * config.h.W32.template: Ditto.
2211 * config.h-vms.template: Ditto.
2212 * config.ami.template: Ditto.
2214 2004-03-04 Paul D. Smith <psmith@gnu.org>
2216 * README.template: Add a note about broken /bin/sh on SunOS
2217 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2219 * misc.c (message, error, fatal): Don't use "..." if we're using
2220 varargs. ansi2knr should handle this but it doesn't work: it
2221 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2222 done. On many systems (SunOS for example) va_dcl is a #define.
2223 So, force the use of the non-"..." version on pre-ANSI compilers.
2225 * maintMakefile (sign-dist): Create some rules to help automate
2226 the new GNU ftp upload method.
2228 2004-02-24 Paul D. Smith <psmith@gnu.org>
2230 * config.h.W32.template: Add HAVE_STDARG_H
2231 * config.h-vms.template: Ditto.
2232 * config.ami.template: Ditto.
2234 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2236 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2237 * build_w32.bat: Remove extra "+".
2239 2004-02-23 Paul D. Smith <psmith@gnu.org>
2241 * make.h: Create an UNUSED macro to mark unused parameters.
2242 * (many): Clean up warnings by applying UNUSED, fixing
2243 signed/unsigned incompatibilities, etc.
2245 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2247 * filedef.h: Name the command_state enumeration.
2248 * file.c (set_command_state): Use the enumeration in the function
2251 * configure.in: Explicitly set SET_MAKE to empty, to disable
2252 MAKE=make even when no make already exists. Fix bug #3823.
2254 2004-02-22 Paul D. Smith <psmith@gnu.org>
2256 * maintMakefile: Perl script to clean up all non-CVS files. Use
2257 it on all the subdirectories for the cvs-clean target.
2259 * main.c (decode_switches): Require non-empty strings for all our
2260 string command-line options. Fixes Debian bug # 164165.
2262 * configure.in: Check for stdarg.h and varargs.h.
2263 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2264 for printing messages.
2265 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2270 A number of patches for OS/2 support from Andreas Buening
2271 <andreas.buening@nexgo.de>:
2273 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2274 disable the SIGCHLD handler.
2275 (reap_children) [OS/2]: Remove special handling of job_rfd.
2276 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2277 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2278 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2279 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2280 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2283 2004-02-21 Paul D. Smith <psmith@gnu.org>
2285 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2286 <mail@kristov.de> reports that if process_begin() fails we don't
2287 handle the error condition correctly in all cases.
2288 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2289 to have a newline on the message.
2291 * job.c (construct_command_argv_internal): Add "test" to UNIX
2292 sh_cmds[]. Fixes Savannah bug # 7606.
2294 2004-02-04 Paul D. Smith <psmith@gnu.org>
2296 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2297 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2298 Hartmut Becker <Hartmut.Becker@hp.com>.
2300 2004-01-21 Paul D. Smith <psmith@gnu.org>
2302 * job.c (load_too_high): Implement an algorithm to control the
2303 "thundering herd" problem when using -l to control job creation
2304 via the load average. The system only recomputes the load once a
2305 second but we can start many jobs in a second. To solve this we
2306 keep track of the number of jobs started in the last second and
2307 apply a weight to try to guess what a correct load would be.
2308 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2309 Also fixes bug #4693.
2310 (reap_children): Decrease the job count for this second.
2311 (start_job_command): Increase the job count for this second.
2313 * read.c (conditional_line): Expand the text after ifn?def before
2314 checking to see if it's a single word. Fixes bug #7257.
2316 2004-01-09 Paul D. Smith <psmith@gnu.org>
2318 * file.c (print_file): Recurse to print all targets in
2319 double-colon rules. Fixes bug #4518, reported (with patch) by
2320 Andrew Chatham <chatham@google.com>.
2322 2004-01-07 Paul D. Smith <psmith@gnu.org>
2324 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2325 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2326 AC_FUNC_SETVBUF_REVERSED.
2328 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2329 (MAKE Variable): Fix Savannah bug #4898.
2331 * job.c (construct_command_argv_internal): Add "!" to the list of
2332 shell escape chars. POSIX sh allows it to appear before a
2333 command, to negate the exit code. Fixes bug #6404.
2335 * implicit.c (pattern_search): When matching an implicit rule,
2336 remember which dependencies have the ignore_mtime flag set.
2337 Original fix provided in Savannah patch #2349, by Benoit
2338 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2340 2003-11-22 Paul D. Smith <psmith@gnu.org>
2342 * README.W32.template (Outputs): Clarification on -j with
2343 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2346 2003-11-02 Paul D. Smith <psmith@gnu.org>
2348 * function.c (func_if): Strip all the trailing whitespace from the
2349 condition, then don't expand it. Fixed bug # 5798.
2351 * expand.c (recursively_expand_for_file): If we're expanding a
2352 variable with no file context, then use the variable's context.
2355 2003-10-21 Paul D. Smith <psmith@gnu.org>
2357 * main.c (log_working_directory): Add newlines to printf()s.
2359 * README.cvs: Add a note to ignore warnings during autoreconf.
2361 * maintMakefile (po_repo): Set a new URL for PO file updates.
2362 (get-config/config.guess get-config/config.sub): Get these files
2363 from the Savannah config project instead of ftp.gnu.org.
2365 2003-10-05 Paul Eggert <eggert@twinsun.com>
2367 * main.c (main): Avoid potential subscript error if environ has
2370 2003-08-22 Paul D. Smith <psmith@gnu.org>
2372 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2373 systems which don't yet implement the C89 standard :-/.
2375 2003-07-18 Paul D. Smith <psmith@gnu.org>
2377 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2378 [WINDOWS32]: Initialize hash.
2380 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2382 * dir.c (read_dirstream): Provide a workaround for broken versions of
2383 the MinGW dirent structure.
2385 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2387 * w32/include/dirent.h: Add __MINGW32__ filter.
2389 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2391 * make.h: Add global declaration of *make_host.
2392 * main.c (print_usage): Remove local declaration of *make_host.
2393 (print_version): Display "This program built for ..." after Copyright
2396 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2398 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2399 execution of "makeinfo --html make.texi".
2401 2003-04-30 Paul D. Smith <psmith@gnu.org>
2403 * build.template: Make some changes to maybe allow this script to
2404 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2406 * README.OS2.template: New file for OS/2 support. Original
2407 contributed by Andreas Buening.
2408 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2411 2003-04-19 Paul D. Smith <psmith@gnu.org>
2413 Fix bug #1405: allow a target to match multiple pattern-specific
2416 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2417 variable.c, where they've always belonged.
2418 * rule.h: Move the prototypes and struct pattern_var as well.
2419 * variable.c (initialize_file_variables): Invoke
2420 lookup_pattern_var() in a loop, until no more matches are found.
2421 If a match is found, create a new variable set for the target's
2422 pattern variables. Then merge the contents of each matching
2423 pattern variable set into the target's pattern variable set.
2424 (lookup_pattern_var): Change this function to be usable
2425 in a loop. It takes a starting position: if NULL, start at the
2426 beginning; if non-NULL, start with the pattern variable after that
2427 position, and return the next matching pattern.
2428 (create_pattern_var): Create a unique instance of
2429 pattern-specific variables for every definition in the makefile.
2430 Don't combine the same pattern together. This allows us to
2431 process the variable handling properly even when the same pattern
2432 is used multiple times.
2433 (parse_variable_definition): New function: break out the parsing
2434 of a variable definition line from try_variable_definition.
2435 (try_variable_definition): Call parse_variable_definition to
2437 (print_variable_data_base): Print out pattern-specific variables.
2438 * variable.h (struct variable): Remember when a variable is
2439 conditional. Also remember its flavor.
2440 (struct pattern_var): Instead of keeping a variable set, we just
2441 keep a single variable for each pattern.
2442 * read.c (record_target_var): Each pattern variable contains only a
2443 single variable, not a set, so create it properly.
2444 * doc/make.texi (Pattern-specific): Document the new behavior.
2446 2003-04-17 Paul D. Smith <psmith@gnu.org>
2448 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2449 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2450 file/directory naming rules for VMS so I can't tell whether this
2453 2003-04-09 Paul D. Smith <psmith@gnu.org>
2455 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2456 DOS-style pathnames: backslash separators and drive specifiers.
2458 2003-03-28 Paul D. Smith <psmith@gnu.org>
2460 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2461 the intermediate flag on all targets. Fixes bug #2515.
2463 2003-03-24 Paul D. Smith <psmith@gnu.org>
2465 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2466 Upgrade to autoconf 2.57 and automake 1.7.3.
2468 * job.c: More OS/2 changes from Andreas Buening.
2470 * file.c (print_file): Fix variable initialization.
2473 * remake.c (notice_finished_file):
2475 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2476 some calls (like readdir()) return NULL in valid situations
2477 without resetting errno. Fixes bug #2846.
2479 2003-02-25 Paul D. Smith <psmith@gnu.org>
2481 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2483 * job.c (_is_unixy_shell) [OS/2]: New function.
2484 Set default shell to /bin/sh.
2485 (reap_children): Close the job_rfd pipe here since we don't use a
2487 (set_child_handler_action_flags): define this to empty on OS/2.
2488 (start_job_command): Close the jobserver pipe and use
2489 child_execute_job() instead of fork/exec.
2490 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2491 rather than exec'ing, then reconfigure stdin/stdout.
2492 (exec_command): Rewrite to use spawn instead of exec. Return the
2495 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2496 in DOS. Handle the TEMP environment variable as in DOS. Don't
2497 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2498 use -j in DOS mode. Use child_execute_job() instead of
2501 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2504 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2505 prototypes that return values.
2507 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2509 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2510 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2512 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2515 2003-02-24 Paul D. Smith <psmith@gnu.org>
2517 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2518 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2519 (child_execute_job) [VMS]: Handle error status properly.
2520 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2522 * function.c (func_shell): Use EINTRLOOP() while reading from the
2523 subshell pipe (Fixes bug #2502).
2524 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2526 * main.c (main): Ditto.
2528 2003-01-30 Paul D. Smith <psmith@gnu.org>
2530 * read.c (eval): eval() was not fully reentrant, because the
2531 collapsed buffer was static. Change it to be an automatic
2532 variable so that eval() can be invoked recursively.
2534 (eval): Apply patch # 1022: fix memory reference error on long
2535 target-specific variable lines.
2536 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2538 * function.c (check_numeric): Combine the is_numeric() function
2539 into this function, since it's only called from one place.
2540 Constify this function. Have it print the incorrect string in the
2541 error message. Fixes bug #2407.
2542 (strip_whitespace): Constify.
2543 (func_if): Constify.
2544 * expand.c (expand_argument): Constify.
2546 2003-01-29 Paul D. Smith <psmith@gnu.org>
2548 Fix bug # 2169, also reported by other people on various systems.
2550 * make.h: Some systems, such as Solaris and PTX, do not fully
2551 implement POSIX-compliant SA_RESTART functionality; important
2552 system calls like stat() and readdir() can still fail with EINTR
2553 even if SA_RESTART has been set on the signal handler. So,
2554 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2555 EINTR for system calls which return -1 or 0 (NULL), respectively,
2557 Also, remove the old atomic_stat()/atomic_readdir() and
2558 HAVE_BROKEN_RESTART handling.
2560 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2562 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2563 * remake.c (touch_file): Ditto.
2565 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2566 * read.c (construct_include_path): Ditto.
2567 * remake.c (name_mtime): Ditto.
2568 * vpath.c (selective_vpath_search): Ditto.
2569 * dir.c (find_directory): Ditto.
2570 (local_stat): Ditto.
2571 (find_directory): Use ENULLLOOP() to wrap opendir().
2572 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2574 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2575 atomic_readdir() handling.
2577 2003-01-22 Paul D. Smith <psmith@gnu.org>
2579 * function.c (func_call): Fix Bug #1744. If we're inside a
2580 recursive invocation of $(call ...), mask any of the outer
2581 invocation's arguments that aren't used by this one, so that this
2582 invocation doesn't "inherit" them accidentally.
2584 2002-12-05 Paul D. Smith <psmith@gnu.org>
2586 * function.c (subst_expand): Valery Khamenia reported a
2587 pathological performance hit when doing substitutions on very
2588 large values with lots of words: turns out we were invoking
2589 strlen() a ridiculous number of times. Instead of having each
2590 call to sindex() call strlen() again, keep track of how much of
2591 the text we've seen and pass the length to sindex().
2593 2002-11-19 Paul D. Smith <psmith@gnu.org>
2595 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2598 2002-11-16 Paul D. Smith <psmith@gnu.org>
2600 * NMakefile.template (OBJS): Add hash.c object file.
2601 * SMakefile.template (srcs): Ditto.
2602 * Makefile.ami (objs): Ditto.
2603 * build_w32.bat: Ditto.
2605 * Makefile.DOS.template: Remove extra dependencies.
2607 2002-10-25 Paul D. Smith <psmith@gnu.org>
2609 * expand.c (install_variable_buffer): New function. Install a new
2610 variable_buffer context and return the previous one.
2611 (restore_variable_buffer): New function. Free the current
2612 variable_buffer context and put a previously saved one back.
2613 * variable.h: Prototypes for {install,restore}_variable_buffer.
2614 * function.c (func_eval): Push a new variable_buffer context
2615 before we eval, then restore the old one when we're done.
2618 * read.c (install_conditionals): New function. Install a new
2619 conditional context and return the previous one.
2620 (restore_conditionals): New function. Free the current
2621 conditional context and put a previously saved one back.
2622 (eval): Use the {install,restore}_conditionals for "include"
2624 (eval_buffer): Use {install,restore}_conditionals to preserve the
2625 present conditional state before we evaluate the buffer.
2628 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2630 (Recursion): Add a variable index entry for CURDIR.
2632 * README.cvs: Update to appropriate versions.
2633 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2634 don't need to copy loadavg.c: automake is smart enough to create
2635 it for me. Still have a bug in automake related to ansi2knr tho.
2637 2002-10-14 Paul D. Smith <psmith@gnu.org>
2639 * remake.c (notice_finished_file): Only touch targets if they have
2640 at least one command (as per POSIX). Resolve Bug #1418.
2642 * *.c: Convert to using ANSI C-style function definitions.
2643 * Makefile.am: Enable the ansi2knr feature of automake.
2644 * configure.in: ditto.
2646 2002-10-13 Paul D. Smith <psmith@gnu.org>
2648 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2649 for automatic variable values like $^, etc. In the case of very
2650 large lists of prerequisites this causes problems. Instead reuse
2651 a static buffer (resizeable) for each variable.
2653 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2654 target-specific variable definitions. Check for it and set an
2656 (record_target_var): Set the export field to v_export if the
2657 "exported" flag is set.
2658 * doc/make.texi (Target-specific): Document the ability to use
2661 * doc/make.texi: Change the name of the section on automatic
2662 variables from "Automatic" to "Automatic Variables". Added text
2663 clarifying the scope of automatic variables.
2665 2002-10-04 Paul D. Smith <psmith@gnu.org>
2667 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2669 (record_files): Ditto.
2671 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2672 the search for the '=' to only within the enclosing parens.
2674 2002-10-03 Paul D. Smith <psmith@gnu.org>
2676 Version 3.80 released.
2678 * dir.c: Change hash functions to use K&R function definition style.
2679 * function.c: Ditto.
2681 * variable.c: Ditto.
2683 Update to automake 1.7.
2685 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2686 (pdf): Remove this target as automake now provides one.
2688 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2690 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2692 * makefile.com: Updates for GNU make 3.80.
2693 * makefile.vms: Ditto.
2695 2002-09-23 Paul D. Smith <psmith@gnu.org>
2697 * read.c (enum make_word_type): Remove w_comment.
2698 (get_next_mword): Don't treat comment characters as special; where
2699 this function is used we will never see a comment (it's stripped
2700 before we get here) and treating comments specially means that
2701 targets like "foo\#bar" aren't handled properly.
2703 2002-09-18 Paul D. Smith <psmith@gnu.org>
2705 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2707 * read.c (eval): Expansion of arguments to export/unexport was
2708 ignoring all arguments after the first one. Change the algorithm
2709 to expand the whole line once, then parse the results.
2711 2002-09-17 Paul D. Smith <psmith@gnu.org>
2713 Fix Bug #940 (plus another bug I found while looking at this):
2715 * read.c (record_target_var): enter_file() will add a new entry if
2716 it's a double-colon target: we don't want to do that in this
2717 situation. Invoke lookup_file() and only enter_file() if it does
2718 not already exist. If the file we get back is a double-colon then
2719 add this variable to the "root" double-colon target.
2721 * variable.c (initialize_file_variables): If this file is a
2722 double-colon target but is not the "root" target, then initialize
2723 the root and make the root's variable list the parent of our
2726 2002-09-13 Paul D. Smith <psmith@gnu.org>
2728 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2730 * hash.c (round_up_2): Get rid of a warning.
2732 2002-09-12 Paul D. Smith <psmith@gnu.org>
2734 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2735 so it doesn't complain about getloadavg.c.
2737 * commands.c (set_file_variables): Make sure we always alloca() at
2738 least 1 character for the value of $? (for '\0').
2740 2002-09-11 Paul D. Smith <psmith@gnu.org>
2742 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2743 macro to use RESULT instead of the incorrect _RESULT_.
2745 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2746 and atomic_readdir(). We need to #include dirent.h to get this to
2748 * misc.c (atomic_readdir): Fix typos.
2750 2002-09-10 Paul D. Smith <psmith@gnu.org>
2752 * read.c (eval): Expand variable lists given to export and
2753 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2754 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2756 * doc/make.texi (Variables/Recursion): Document this.
2757 (Conditional Syntax): And here.
2759 2002-09-09 Paul D. Smith <psmith@gnu.org>
2761 * configure.in: Check for memmove().
2763 2002-09-07 Paul D. Smith <psmith@gnu.org>
2765 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2766 Michael Sterrett <msterret@coat.com> reports that while it has
2767 SA_RESTART, it does not work properly.
2769 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2770 that invokes stat() and loops to do it again if it returns EINTR.
2771 (atomic_readdir): Ditto, with readdir().
2773 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2774 and readdir() to atomic_stat() and atomic_readdir().
2776 2002-09-04 Paul D. Smith <psmith@gnu.org>
2778 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2779 reports that GNU make sometimes doesn't recognize that targets can
2780 be made, when directories can be created as prerequisites. He
2781 reports that changing the order of predicates in the DEP->changed
2782 flag test so that lookup_file() is always performed, solves this
2785 2002-08-08 Paul D. Smith <psmith@gnu.org>
2787 * configure.in: Require a newer version of gettext.
2789 * misc.c (perror_with_name): Translate the format string (for
2790 right-to-left language support).
2791 (pfatal_with_name): Ditto.
2793 * main.c: Create a static array of strings to store the usage
2794 text. This is done to facilitate translations.
2795 (struct command_switch): Remove argdesc and description fields.
2796 (switches): Remove values for obsolete fields.
2797 (print_usage): Print each element of the usage array.
2799 * hash.c: Change function definitions to be K&R style.
2801 2002-08-02 Paul D. Smith <psmith@gnu.org>
2803 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2804 this one because it's too hard to get right. We'll look at it for
2806 * main.c (main): Don't create the .TARGETS variable.
2807 * variable.c (handle_special_var): Don't handle .TARGETS.
2809 2002-08-01 Paul D. Smith <psmith@gnu.org>
2811 * main.c (switches): Add a new option, -B (--always-make). If
2812 specified, make will rebuild all targets that it encounters even
2813 if they don't appear to be out of date.
2814 (always_make_flag): New flag.
2815 * make.h: Extern always_make_flag.
2816 * remake.c (update_file_1): Check always_make_flag; if it's set we
2817 will always rebuild any target we can, even if none of its
2818 prerequisites are newer.
2821 * doc/make.texi (Shell Function): Make it clear that make
2822 variables marked as "export" are not passed to instances of the
2825 Add new introspection variable .VARIABLES and .TARGETS.
2827 * variable.c (handle_special_var): New function. If the variable
2828 reference passed in is "special" (.VARIABLES or .TARGETS),
2829 calculate the new value if necessary. .VARIABLES is handled here:
2830 walk through the hash of defined variables and construct a value
2831 which is a list of the names. .TARGETS is handled by
2832 build_target_list().
2833 (lookup_variable): Invoke handle_special_var().
2834 * file.c (build_target_list): Walk through the hask of known files
2835 and construct a list of the names of all the ones marked as
2837 * main.c (main): Initialize them to empty (and as simple variables).
2838 * doc/make.texi (Special Variables): Document them.
2839 * NEWS: Mention them.
2841 * variable.h (struct variable): Add a new flag "exportable" which
2842 is true if the variable name is valid for export.
2843 * variable.c (define_variable_in_set): Set "exportable" when a new
2844 variable is defined.
2845 (target_environment): Use the "exportable" flag instead of
2846 re-checking the name here... an efficiency improvement.
2848 2002-07-31 Paul D. Smith <psmith@gnu.org>
2850 * config.h-vms.template: Updates to build on VMS. Thanks to
2851 Brian_Benning@aksteel.com for helping verify the build.
2852 * makefile.com: Build the new hash.c file.
2853 * hash.h: Use strcpmi(), not stricmp(), in the
2854 HAVE_CASE_INSENSITIVE_FS case.
2856 2002-07-30 Paul D. Smith <psmith@gnu.org>
2858 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2859 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2860 Reported by <Brian_Benning@aksteel.com>.
2862 2002-07-10 Paul D. Smith <psmith@gnu.org>
2864 * variable.c (pop_variable_scope): Remove variable made unused by
2865 new hash infrastructure.
2866 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2867 comparisons as well as name comparisons.
2868 * variable.h: Add a prototype for new hash_init_function_table().
2869 * file.c (lookup_file): Remove variables made unused by new hash
2871 * dir.c (directory_contents_hash_2): Missing return of hash value.
2872 (dir_contents_file_exists_p): Remove variables made unused by new
2873 hash infrastructure.
2876 Installed Greg McGary's integration of the hash functions from the
2877 GNU id-utils package:
2879 2002-07-10 Greg McGary <greg@mcgary.org>
2881 * scripts/functions/filter-out: Add literals to to the
2882 pattern space in order to add complexity, and trigger
2883 use of an internal hash table. Fix documentation strings.
2884 * scripts/targets/INTERMEDIATE: Reverse order of files
2885 passed to expected `rm' command.
2887 2002-07-10 Greg McGary <greg@mcgary.org>

2979 2002-07-10 Paul D. Smith <psmith@gnu.org>
2981 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2982 prerequisite list. A real SysV make will expand the entire
2983 prerequisites list _twice_: we don't do that as it's a big
2984 backward-compatibility problem. We only replace those specific
2987 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2988 references left in the list of prerequisites. Check for .POSIX as
2989 we record targets, so we can disable non-POSIX behavior while
2990 reading makefiles as well as running them.
2991 (eval): Check the prerequisite list to see if we have anything
2992 that looks like a SysV prerequisite variable reference.
2994 2002-07-09 Paul D. Smith <psmith@gnu.org>
2996 * doc/make.texi (Prerequisite Types): Add a new section describing
2997 order-only prerequisites.
2999 * read.c (uniquize_deps): If we have the same file as both a
3000 normal and order-only prereq, get rid of the order-only prereq,
3001 since the normal one supersedes it.
3003 2002-07-08 Paul D. Smith <psmith@gnu.org>
3005 * AUTHORS: Added Greg McGary to the AUTHORS file.
3006 * NEWS: Blurbed order-only prerequisites.
3007 * file.c (print_file): Show order-only deps properly when printing
3010 * maintMakefile: Add "update" targets for wget'ing the latest
3011 versions of various external files. Taken from Makefile.maint in
3014 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3015 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3017 2002-07-07 Paul D. Smith <psmith@gnu.org>
3019 * po/*.po: Remove. We'll use wget to retrieve them at release
3022 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3023 rather than a shell you get an exception. Make sure we look up
3024 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3026 * remake.c (notice_finished_file): Fix handling of -t flag.
3027 Patch provided by Henning Makholm <henning@makholm.net>.
3029 * implicit.c (pattern_search): Some systems apparently run short
3030 of stack space, and using alloca() in this function caused an
3031 overrun. I modified it to use xmalloc() on the two variables
3032 which seemed like they might get large. Fixes Bug #476.
3034 * main.c (print_version): Update copyright notice to conform with
3036 (print_usage): Update help output.
3038 * function.c (func_eval): Create a new make function, $(eval
3039 ...). Expand the arguments, put them into a buffer, then invoke
3040 eval_buffer() on the resulting string.
3041 (func_quote): Create a new function, $(quote VARNAME). Inserts
3042 the value of the variable VARNAME without expanding it any
3045 * read.c (struct ebuffer): Change the linebuffer structure to an
3046 "eval buffer", which can be either a file or a buffer.
3047 (eval_makefile): Move the code in the old read_makefile() which
3048 located a makefile into here: create a struct ebuffer with that
3049 information. Have it invoke the new function eval() with that
3051 (eval_buffer): Create a new function that creates a struct ebuffer
3052 that holds a string buffer instead of a file. Have it invoke
3053 eval() with that ebuffer.
3054 (eval): New function that contains the guts of the old
3055 read_makefile() function: this function parses makefiles. Obtains
3056 data to parse from the provided ebuffer. Some modifications to
3057 make the flow of the function cleaner and clearer. Still could
3058 use some work here...
3059 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3060 contents of the define/endef variable from the ebuffer.
3061 (readstring): Read the next line from a string-style ebuffer.
3062 (readline): Read the next line from an ebuffer. If it's a string
3063 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3066 * dep.h (eval_buffer): Prototype eval_buffer();
3068 * variable.c (do_variable_definition): Make sure that all
3069 non-target-specific variables are registered in the global set.
3070 If we're invoked from an $(eval ...) we might be inside a $(call
3071 ...) or other function which has pushed a variable scope; we still
3072 want to define our variables from evaluated makefile code in the
3075 2002-07-03 Greg McGary <greg@mcgary.org>
3077 * dep.h (struct dep) [ignore_mtime]: New member.
3078 [changed]: convert to a bitfield.

3080 * main.c (main, handle_non_switch_argument): Likewise.
3081 * rule.c (convert_suffix_rule): Likewise.
3082 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3083 (read_makefile): Parse '|' in prerequisite list.
3084 (uniquize_deps): Consider ignore_mtime when comparing deps.
3085 * remake.c (update_file_1, check_dep): Don't force remake for
3086 dependencies that have d->ignore_mtime.
3087 * commands.c (FILE_LIST_SEPARATOR): New constant.
3088 (set_file_variables): Don't include a
3089 prerequisite in $+, $^ or $? if d->ignore_mtime.
3092 2002-06-18 Paul D. Smith <psmith@gnu.org>
3094 * make.texinfo: Updates for next revision. New date/rev/etc.
3095 Recreate all Info menus. Change license on the manual to the GNU
3096 Free Documentation License. A number of typos.
3097 (Variables Simplify): Don't use "-" before it's defined.
3098 (Automatic Prerequisites): Rewrite the target example to work
3099 properly if the compile fails. Remove incorrect comments about
3100 how "set -e" behaves.
3101 (Text Functions): Move the "word", "wordlist", "words", and
3102 "firstword" functions here, from "File Name Functions".
3103 * make-stds.texi: Update from latest GNU version.
3104 * fdl.texi: (created) Import the latest GNU version.
3106 2002-06-06 Paul D. Smith <psmith@gnu.org>
3108 * variable.c (do_variable_definition): New function: extract the
3109 part of try_variable_definition() that actually sets the value
3110 into a separate function.
3111 (try_variable_definition): Call do_variable_definition() after
3112 parsing the variable definition string.
3113 (define_variable_in_set): Make the name argument const.
3115 * variable.h (enum variable_flavor): Make public.
3116 (do_variable_definition): Create prototype.
3118 * read.c (read_all_makefiles): Create a new built-in variable,
3120 (read_makefile): Add each makefile read in to this variable value.
3122 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3124 * Makefile.DOS.template: Tweak according to changes in the
3125 distribution. Add back the dependencies of *.o files.
3127 * configh.dos.template: Synchronize with config.h.in.
3129 2002-05-09 Paul D. Smith <psmith@gnu.org>
3131 * file.c (file_timestamp_now): Use K&R function declaration.
3133 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3134 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3135 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3136 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3137 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3138 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3139 nlist.n_name is a pointer rather than an array.
3141 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3142 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3143 * configure.in: Use it instead of the old version.
3145 * main.c (main): Prefer setvbuf() to setlinebuf().
3147 2002-05-08 Paul D. Smith <psmith@gnu.org>
3149 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3150 (loadavg_LDADD): Ditto.
3152 2002-04-29 Paul D. Smith <psmith@gnu.org>
3154 * expand.c (recursively_expand_for_file): Rename
3155 recursively_expand() to recursively_expand_for_file() and provide
3156 an extra argument, struct file. If the argument is provided, set
3157 the variable scope to that of the file before expanding.
3158 * variable.h (recursively_expand): Make this a macro that invokes
3159 recursively_expand_for_file() with a NULL file pointer.
3160 * variable.c (target_environment): Call the renamed function and
3161 provide the current file context.
3162 Fixes Debian bug #144306.
3164 2002-04-28 Paul D. Smith <psmith@gnu.org>
3166 Allow $(call ...) user-defined variables to be self-referencing
3167 without throwing an error. Allows implementation of transitive
3168 closures, among other possibly useful things.
3169 Requested by: Philip Guenther <guenther@sendmail.com>
3171 * variable.h (struct variable): Add a new field: exp_count, and
3172 new macros to hold its size and maximum value.
3173 (warn_undefined): Make this a macro.
3174 * variable.c (define_variable_in_set): Initialize it.
3175 * expand.c (recursively_expand): If we detect recursive expansion
3176 of a variable, check the exp_count field. If it's greater than 0
3177 allow the recursion and decrement the count.
3178 (warn_undefined): Remove this (now a macro in variable.h).
3179 * function.c (func_call): Before we expand the user-defined
3180 function, modify its exp_count field to contain the maximum
3181 number of recursive calls we'll allow. After the call, reset it
3184 2002-04-21 Paul D. Smith <psmith@gnu.org>
3186 Modified to use latest autoconf (2.53), automake (1.6.1), and
3187 gettext (0.11.1). We're using gettext's new "external" support,
3188 to avoid including libintl source with GNU make.
3190 * README.cvs: New file. Explain how to build GNU make from CVS.
3192 * configure.in: Modify checking for the system glob library.
3193 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3194 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3195 etc. will manage it correctly). Set an automake conditional
3196 USE_LOCAL_GLOB to decide whether to compile the glob library.
3198 * getloadavg.c (main): Include make.h in the "TEST" program to
3201 * Makefile.am: Remove special rules for loadavg. Replace them
3202 with Automake capabilities for building extra programs.
3204 * signame.c: This file does nothing if the system provide
3205 strsignal(). If not, it implements strsignal(). If the system
3206 doesn't define sys_siglist, then we make our own; otherwise we use
3208 * signame.h: Removed.
3210 * main.c (main): No need to invoke signame_init(). Update copyright.
3212 * ABOUT-NLS: Removed.
3213 * gettext.c: Removed.
3214 * gettext.h: Get a simplified copy from the gettext package.
3216 * i18n/*.po: Moved to po/.
3219 * config/*: Created. Contains package configuration helper files.
3220 * config.guess, config.sub: Moved to config directory.
3222 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3223 Rework to use new-style autoconf features. Use the "external"
3224 mode for gettext. Make the build.sh config file conditional on
3225 whether build.sh.in exists, to avoid autoconf errors.
3226 * acinclude.m4: Removed almost all macros as being obsolete.
3227 Rewrote remaining macros to use AC_DEFINE.
3228 * acconfig.h: Removed.
3230 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3231 conditional to handle customs support. Remove special handling
3234 2002-04-20 Paul D. Smith <psmith@gnu.org>
3236 * function.c (func_call): Don't mark the argument variables $1,
3237 etc. as recursive. They've already been fully expanded so
3238 there's no need to do it again, and doing so strips escaped $'s.
3239 Reported by Sebastian Glita <glseba@yahoo.com>.
3241 * remake.c (notice_finished_file): Walk through double-colon
3242 entries via the prev field, not the next field!
3243 Reported by Greg McGary <greg@mcgary.org>.
3245 * main.c (main): If the user specifies -q and asks for a specific
3246 target which is a makefile, we got an assert. In that case it
3247 turns out we should continue normally instead.
3249 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3251 * i18n/he.po: Installed a new translation.
3253 2002-01-07 Paul D. Smith <psmith@gnu.org>
3255 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3257 2001-12-04 Paul D. Smith <psmith@gnu.org>
3259 * i18n/ja.po: Installed an updated translation.
3261 2001-09-06 Paul Eggert <eggert@twinsun.com>
3263 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3264 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3266 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3268 (main): Get rid of any avoidable limit on stack size.
3270 2001-09-04 Paul D. Smith <psmith@gnu.org>
3272 * i18n/da.po: Installed an updated translation.
3274 2001-08-03 Paul D. Smith <psmith@gnu.org>
3276 * i18n/fr.po: Installed an updated translation.
3277 Resolves Debian bug #106720.
3279 2001-06-13 Paul D. Smith <psmith@gnu.org>
3281 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3284 2001-06-11 Paul D. Smith <psmith@gnu.org>
3286 * i18n/ko.po: Installed a new translation.
3288 2001-05-06 Paul D. Smith <psmith@gnu.org>
3290 Modify the EINTR handling.
3292 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3293 the way in which we manage the file descriptor/signal handler race
3294 trap to be more efficient.
3296 2001-05-06 Paul Eggert <eggert@twinsun.com>
3298 Restart almost all system calls that are interrupted, instead
3299 of worrying about EINTR. The lone exception is the read() for
3302 * configure.in (HAVE_SA_RESTART): New macro.
3303 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3304 * main.c (main): Use SA_RESTART instead of the old,
3305 nonstandard SA_INTERRUPT.
3307 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3308 * main.c (bsd_signal): New function or macro,
3309 if the implementation doesn't supply it.
3310 (The bsd_signal function will be in POSIX 1003.1-200x.)
3311 (HANDLESIG): Remove.
3312 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3314 * make.h (EINTR_SET): Remove.
3315 (SA_RESTART): New macro.
3317 * arscan.c (ar_member_touch): Don't worry about EINTR.
3318 * function.c (func_shell): Likewise.
3319 * job.c (reap_children, free_child, new_job): Likewise.
3320 * main.c (main): Likewise.
3321 * remake.c (touch_file, name_mtime): Likewise.
3323 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3324 if fstat failed with errno!=EINTR, the error was ignored.
3326 * job.c (set_child_handler_action_flags): New function.
3327 (new_job): Use it to temporarily clear the SIGCHLD action flags
3328 while reading the token.
3330 2001-05-02 Paul D. Smith <psmith@gnu.org>
3332 * job.c (start_job_command): Don't add define/endef per-line flags
3333 to the top-level flags setting.
3335 2001-04-03 Paul D. Smith <psmith@gnu.org>
3337 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3338 bit on error, so check for odd return values, not non-0 return
3340 (VMS_get_member_info): Calculate the timezone differences correctly.
3341 Reported by John Fowler <jfowler@nyx.net>.
3344 2001-03-14 Paul D. Smith <psmith@gnu.org>
3346 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3347 value before invoking define_variable().
3348 Reported by John Fowler <jfowler@nyx.net>.
3350 2001-02-07 Paul D. Smith <psmith@gnu.org>
3352 * read.c (record_target_var): If we reset the variable due to a
3353 command-line variable setting overriding it, turn off the "append"
3356 2001-01-17 Paul D. Smith <psmith@gnu.org>
3358 * variable.c (lookup_variable) [VMS]: When getting values from the
3359 environment, allocate enough space for the _value_ plus escapes,
3360 not enough space for the name plus escapes :-/.
3361 Reported by John Fowler <jfowler@nyx.net>.
3363 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3364 warnings that make generates, so it doesn't look like an error.
3365 Reported by Karl Berry <karl@gnu.org>.
3368 Fix for PR/2020: Rework appended target-specific variables. I'm
3369 fairly confident this algorithm is finally correct.
3371 * expand.c (allocated_variable_append): Rewrite. Instead of
3372 expanding each appended variable then adding all the expanded
3373 strings together, we append all the unexpanded values going up
3374 through the variable set contexts, then expand the final result.
3375 This behaves just like non-target-specific appended variable
3376 values, while the old way didn't in various corner cases.
3377 (variable_append): New function: recursively append the unexpanded
3378 value of a variable, walking from the outermost variable scope to
3380 * variable.c (lookup_variable): Remove the code that looked up the
3381 variable set list if the found variable was "append". We don't
3383 (lookup_variable_in_set): Make this non-static so we can use it
3385 (try_variable_definition): Use lookup_variable_in_set() rather
3386 than faking out current_variable_set_list by hand (cleanup).
3387 * variable.h: Add a prototype for the now non-static
3388 lookup_variable_in_set().
3390 2000-11-17 Paul D. Smith <psmith@gnu.org>
3392 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3393 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3394 before throwing a fit.
3396 2000-11-17 Paul D. Smith <psmith@gnu.org>
3398 * read.c (readline): CRLF calculations had a hole, if you hit the
3399 buffer grow scenario just right. Reworked the algorithm to avoid
3400 the need for len or lastlen at all. Problem description with
3401 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3403 2000-10-24 Paul D. Smith <psmith@gnu.org>
3405 * gettext.c (SWAP): Declare this with the prototype, otherwise
3406 some systems don't work (non-32-bit? Reported for Cray T3E).
3407 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3409 2000-10-05 Paul D. Smith <psmith@gnu.org>
3411 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3412 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3414 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3416 2000-09-22 Paul D. Smith <psmith@gnu.org>
3418 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3419 parts of the real gettext.h here, and we expect to really include
3420 the real gettext.h later. If we keep this #define, it's ignored.
3422 2000-09-21 Paul D. Smith <psmith@gnu.org>
3424 * main.c (log_working_directory): Rework the text to use complete
3425 sentences, to make life simpler for the translators.
3427 2000-08-29 Paul D. Smith <psmith@gnu.org>
3429 * file.c (remove_intermediates): Print a debug message before we
3430 remove intermediate files, so the user (if she uses -d) knows
3433 2000-08-21 Paul D. Smith <psmith@gnu.org>
3435 * variable.c (try_variable_definition): Change how we handle
3436 target-specific append variable defns: instead of just setting the
3437 value, expand it as an append _but_ only within the current
3438 target's context. Otherwise we lose all but the last value if the
3439 variable is appended more than once within the current target
3440 context. Fixes PR/1831.
3442 2000-08-16 Paul D. Smith <psmith@gnu.org>
3444 * function.c (func_shell): Nul-terminate the buffer before
3445 printing an exec error message (just in case it's not!).
3446 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3448 2000-07-25 Paul D. Smith <psmith@gnu.org>
3450 * job.c (construct_command_argv_internal): Add "~" to the list of
3451 sh_chars[] which disallow optimizing out the shell call.
3453 2000-07-23 Paul Eggert <eggert@twinsun.com>
3455 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3456 supersedes --disable-nsec-timestamps.
3457 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3458 * README: Remove --disable-nsec-timestamps.
3460 * filedef.h (struct file.low_resolution_time): New member.
3461 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3462 * remake.c (update_file_1):
3463 Avoid spurious rebuilds due to low resolution time stamps,
3464 generalizing the earlier code that applied only to archive members.
3465 (f_mtime): Archive members always have low resolution time stamps.
3467 * configure.in: Remove --disable-nsec-timestamps, as this has
3468 been superseded by .LOW_RESOLUTION_TIME.
3470 2000-07-23 Paul Eggert <eggert@twinsun.com>
3472 * configure.in (enable_nsec_timestamps): Renamed from
3473 make_cv_nsec_timestamps, since enable/disable options
3474 shouldn't be cached.
3476 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3477 and Paul Eggert <eggert@twinsun.com>
3479 * file.c (file_timestamp_now):
3480 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3481 so that clock_gettime is not linked unless needed.
3483 * filedef.h (FILE_TIMESTAMP_HI_RES):
3484 Remove definition; "configure" now does this.
3486 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3487 to before high resolution file timestamp check,
3488 since that check now uses uintmax_t.
3489 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3490 high resolution file timestamps.
3491 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3492 so that we don't link in clock_gettime unnecessarily.
3494 2000-07-17 Paul D. Smith <psmith@gnu.org>
3496 * i18n/ja.po: New version of the translation file.
3498 2000-07-07 Paul D. Smith <psmith@gnu.org>
3500 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3501 the offset calculation.
3502 (name_mtime): Replace EINTR test with EINTR_SET macro.
3504 2000-07-07 Paul Eggert <eggert@twinsun.com>
3508 * remake.c (update_file_1):
3509 Avoid spurious rebuilds of archive members due to their
3510 timestamp resolution being only one second.
3511 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3512 the clock's resolution being lower than file timestamps'.
3513 When warning about future timestamps, report only the discrepancy,
3514 not the absolute value of the timestamp and the current time.
3516 * file.c (file_timestamp_now): New arg RESOLUTION.
3517 * filedef.h (file_timestamp_now): Likewise.
3518 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3520 2000-07-05 Paul D. Smith <psmith@gnu.org>
3522 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3523 to listp. Fixes PR/1793.
3525 2000-06-26 Paul Eggert <eggert@twinsun.com>
3527 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3529 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3531 * remake.c (f_mtime): Remove unused var memtime.
3533 2000-06-25 Martin Buchholz <martin@xemacs.org>
3535 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3536 Ran spell-check on make.texinfo.
3538 2000-06-23 Paul D. Smith <psmith@gnu.org>
3540 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3541 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3542 * make.h: Define these macros.
3544 * Version 3.79.1 released.
3546 * configure.in: Add a new option, --disable-nsec-timestamps, to
3547 avoid using sub-second timestamps on systems that support it. It
3548 can lead to problems, e.g. if your makefile relies on "cp -p".
3549 * README.template: Document the issue with "cp -p".
3551 * config.guess, config.sub: Updated.
