1 2009-09-24 Paul Smith <psmith@gnu.org>
3 * implicit.c (pattern_search): Add back support for order-only
4 prerequisites for secondary expansion implicit rules, that were
5 accidentally dropped. If we find a "|", enable order-only mode
6 and set IGNORE_MTIME on all deps that are seen afterward.
7 (pattern_search): Fix memory leaks: for intermediate files where
8 we've already set the file variable and pattern variable sets, be
9 sure to either save or free them as appropriate.
11 2009-09-23 Paul Smith <psmith@gnu.org>
13 Rework the way secondary expansion is stored, for efficiency.
14 This changes secondary expansion so that ONLY WHEN we know we have
15 a possibility of needing secondary expansion, do we defer the
16 secondary expansion. This means more parsing the deps but we use
17 a lot less memory (due to the strcache). Also, this fixes
20 * read.c (eval): Don't parse the dep string here anymore.
21 (record_files): Take the dep argument as an unparsed string. If
22 secondary expansion is enabled AND the prereq string has a '$' in
23 it, then set NEED_2ND_EXPANSION and keep the entire string.
24 Otherwise, parse the dep string here to construct the dep list
25 with the names in the strcache.
27 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
28 duplicate the name string (others are in the strcache).
30 * implicit.c: Remove struct idep and free_idep_chain(): unused.
31 (struct patdeps): New structure to store prereq information.
32 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
33 which prerequisites need expansion, and expand only those.
35 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
36 and enter_prereqs(). split_prereqs() takes a fully-expanded string
37 and splits it into a DEP list, handling order-only prereqs.
38 (enter_prereqs): This function enters a list of DEPs into the file
39 database. If there's a stem defined, expand any pattern chars.
40 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
41 set. Use the above functions.
42 (snap_deps): Only perform second expansion on prereqs that need it,
43 as defined by the NEED_2ND_EXPANSION flag.
44 (print_prereqs): New function to print the prereqs
45 (print_file): Call print_prereqs() rather than print inline.
47 * hash.h (STRING_COMPARE): Take advantage of strcache() by
49 (STRING_N_COMPARE): Ditto.
50 (ISTRING_COMPARE): Ditto.
52 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
53 (parse_file_seq): Return void*
54 * read.c (parse_file_seq): Return void*.
55 (eval): Invoke macroized version of parse_file_seq()
56 * default.c (set_default_suffixes): Ditto.
57 * file.c (split_prereqs): Ditto.
58 * function.c (string_glob): Ditto.
59 * main.c (main): Ditto.
60 * rule.c (install_pattern_rule): Ditto.
62 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
64 2009-09-16 Paul Smith <psmith@gnu.org>
66 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
68 * dep.h: Create alloc_dep() / free_dep() macros.
70 * implicit.c (pattern_search): Take advantage of the new
71 parse_file_seq() to add the directory prefix to each prereq.
73 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
74 all. Avoid reversing chains. Support adding prefixes.
75 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
76 cached/non-cached results.
77 (eval): Remove multi_glob() & invoke new parse_file_seq().
78 * rule.c (install_pattern_rule): Ditto.
79 * main.c (main): Ditto.
80 * implicit.c (pattern_search): Ditto.
81 * function.c (string_glob): Ditto.
82 * file.c (parse_prereqs): Ditto.
83 * default.c (set_default_suffixes): Ditto.
85 * variable.c (parse_variable_definition): Don't run off the end of
86 the string if it ends in whitespace (found with valgrind).
88 * commands.c (set_file_variables): Keep space for all targets in
89 $? if -B is given (found with valgrind).
91 2009-09-15 Paul Smith <psmith@gnu.org>
93 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
94 (xcalloc): Add new function.
95 * make.h: New declarations.
97 * ar.c (ar_glob_match): New calling method for concat().
98 * main.c (main): Ditto.
99 (decode_env_switches): Ditto.
100 * read.c (eval_makefile): Ditto.
101 (tilde_expand): Ditto.
102 (parse_file_seq): Ditto.
103 * variable.c (target_environment): Ditto.
104 (sync_Path_environment): Ditto.
106 * ar.c (ar_glob_match): Use xcalloc().
107 * dir.c (file_impossible): Ditto.
108 * file.c (enter_file): Ditto.
109 * job.c (new_job): Ditto.
110 * read.c (parse_file_seq): Ditto.
111 * vmsfunctions.c (opendir): Ditto.
113 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
115 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
116 inside the loop that looks up environment for PATH.
118 2009-08-31 Eli Zaretskii <eliz@gnu.org>
120 * function.c (windows32_openpipe): Update envp after calling
121 sync_Path_environment.
123 2009-08-02 Paul Smith <psmith@gnu.org>
125 * remake.c (notice_finished_file): Ensure file->cmds is not null
126 before looping through them. Fixes Savannah bug #21824.
128 * doc/make.texi (Wildcard Examples): Clarify when objects is
129 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
130 (Include): Clarify the behavior of -include.
131 Fixes Savannah bug #18963.
133 2009-08-01 Paul Smith <psmith@gnu.org>
135 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
136 etc. come on the command line. Fixes Savannah bug #27093.
138 * expand.c (expand_argument): If the argument is large enough use
139 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
141 * variable.c (do_variable_definition): Avoid using alloca() to
142 hold values, which can be large. Fixes Savannah bug #23960.
144 * job.c (new_job): Use memmove() instead of strcpy() since both
145 pointers are in the same memory block. Fixes Savannah bug #27148.
146 Patch by Petr Machata.
148 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
150 * job.c (construct_command_argv_internal): Add "ulimit" and
151 "unset" to the sh_cmds for Unixy shells.
153 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
155 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
156 that set make_cv_sys_gnu_glob, so they are also correctly set
157 when the cache has been populated before.
159 2009-07-04 Eli Zaretskii <eliz@gnu.org>
161 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
162 exist, as realpath(3) does where it's supported.
164 2006-07-04 Eli Zaretskii <eliz@gnu.org>
166 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
167 (abspath): Support systems that define HAVE_DOS_PATHS (have
168 drive letters in their file names). Use IS_PATHSEP instead of a
169 literal '/' comparison. Fixes Savannah bug #26886.
171 2009-06-14 Paul Smith <psmith@gnu.org>
173 * remake.c (update_file_1): Remember the original file we marked
174 as updating, so we can clear that flag again. If we find a target
175 via vpath, FILE might change.
176 (check_dep): Ditto. Fixes Savannah bug #13529.
177 Patch by Reid Madsen <reid.madsen@tek.com>.
179 2009-06-13 Paul Smith <psmith@gnu.org>
181 * doc/make.texi (MAKEFILES Variable): Be explicit that files
182 included by MAKEFILES cannot give default goals.
183 * read.c (eval): If set_default is not set, pass the no-default-goal
184 value when we read included makefiles. Fixes Savannah bug #13401.
186 * ar.c (ar_name): Ensure that targets with empty parens aren't
187 considered archive member references: archive members must have a
188 non-empty "member" string. Fixes Savannah bug #18435.
190 * function.c (string_glob): Rely on multi_glob() to determine
191 whether files exist or not. Remove call to file_exists_p() which
192 is not always correct. Fixes Savannah bug #21231.
193 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
194 then only files that really exist will be returned.
195 * dep.h: Add new argument to multi_glob().
196 * rule.c (install_pattern_rule): Ditto.
197 * read.c (eval): Ditto.
198 * main.c (main): Ditto.
199 * implicit.c (pattern_search): Ditto.
200 * file.c (parse_prereqs): Ditto.
201 * default.c (set_default_suffixes): Ditto.
203 2009-06-09 Paul Smith <psmith@gnu.org>
205 * commands.c (set_file_variables): If always_make_flag is set,
206 always add the prereq to $?. Fixes Savannah bug #17825.
208 * remake.c (update_file_1): When rebuilding deps of FILE, also try
209 to rebuild the deps of all the also_make targets for that file.
210 Fixes Savannah bug #19108.
212 * implicit.c (pattern_search): Undo test for is_target, added by
213 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
214 Rule Search Algorithm". Fixes Savannah bug #17752.
216 * main.c (clean_jobserver): Clear the jobserver_fds options and
217 set job_slots to the default when we clean up.
218 (define_makeflags): Return the new MAKEFLAGS value.
219 (main): Reset MAKEFLAGS in the environment when we re-exec.
220 Fixes Savannah bug #18124.
222 2009-06-08 Paul Smith <psmith@gnu.org>
224 * read.c (eval): Collapse continuations post-semicolon on target-
225 specific variables. Fixes Savannah bug #17521.
227 2009-06-07 Paul Smith <psmith@gnu.org>
229 * job.c (reap_children): For older systems without waitpid() (are
230 there any of these left?) run wait(2) inside EINTRLOOP to handle
231 EINTR errors. Fixes Savannah bug #16401.
233 * (various): Debug message cleanup. Fixes Savannah bug #16469.
235 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
237 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
238 not the end, to catch second expansion $(eval ...) defining new
239 target/prereq relationships during snap_deps.
240 Fixes Savannah bug #24622.
242 * read.c (record_files): The second-expansion "f->updating" hack
243 was not completely correct: if assumed that the target with
244 commands always had prerequisites; if one didn't then the ordering
245 was messed up. Fixed for now to use f->updating to decide whether
246 to preserve the last element in the deps list... but this whole
247 area of constructing and reversing the deps list is too confusing
248 and needs to be reworked. Fixes Savannah bug #21198.
250 2009-06-06 Paul Smith <psmith@gnu.org>
252 * hash.c (hash_insert): Remove useless test for NULL.
253 Fixes Savannah bug #21823.
255 * make.h: Move SET_STACK_SIZE determination to make.h.
256 * main.c (main): New global variable, STACK_LIMIT, holds the
257 original stack limit when make was started.
258 * job.c (start_job_command): Reset the stack limit, if we changed it.
259 Fixes Savannah bug #22010.
261 * remake.c (check_dep): Only set the target's state to not-started
262 if it's not already running. Found this while testing -j10 builds
263 of glibc: various targets were being rebuilt multiple times.
264 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
267 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
268 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
271 2009-06-04 Paul Smith <psmith@gnu.org>
273 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
275 * maintMakefile: Modify access of config and gnulib Savannah
276 modules to use GIT instead of CVS.
278 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
279 Fixes Savannah bug #24655.
281 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
282 this can happen during some invocations of $(eval ...) for example.
283 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
285 2009-06-02 Paul Smith <psmith@gnu.org>
287 * configure.in: Check for fileno()
288 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
289 for the makefile file so invocations of $(shell ...) don't inherit it.
290 Fixes Savannah bug #24277.
292 2009-06-01 Paul Smith <psmith@gnu.org>
294 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
295 expansion was handled incorrectly. Rework the default goal
296 handling to save the variable only. Remove default_goal_file and
298 * read.c (eval): Check default_goal_var, not default_goal_name.
299 * read.c (record_target_var): Don't check default_goal_file here.
301 2009-05-31 Paul Smith <psmith@gnu.org>
303 * main.c (main): Expand the .DEFAULT_GOAL variable before using
304 it, and if the multi_glob() returns nothing (say it expanded to
305 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
307 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
308 $(and ..) to the reference. Fixes Savannah bug #25694.
310 * make.1: Be clear that some recipes will be executed even with -n.
311 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
313 * doc/make.texi (Override Directive): Make more clear how
314 overrides and appends interact.
315 Elucidates part of Savannah bug #26207.
317 * read.c (record_target_var): Don't reset the origin on
318 target-specific variables; try_variable_definition() will handle
319 this correctly. Fixes Savannah bug #26207.
321 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
322 Fixes Savannah bug #25712.
324 * implicit.c (pattern_search): Keep a pointer to the beginning of
325 the filename and save that instead of the constructed pointer.
326 Fixes Savannah bug #26593.
327 Patch by Mark Seaborn <mrs@mythic-beasts.com>
329 2009-05-30 Paul Smith <psmith@gnu.org>
331 * doc/make.texi (Multi-Line): Add a description of the new abilities
332 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
333 "command sequence" vs. "recipe" syntax.
334 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
335 after a define, to create variables with those flavors.
337 2009-05-25 Paul Smith <psmith@gnu.org>
339 Reworked the parser for variable assignments to allow multiple
340 modifiers, and in any order. Also allows variable and
341 prerequisites to be modifier names ('export', 'private', etc.)
343 * NEWS: Add notes about user-visible changes.
345 * read.c (struct vmodifiers): Remember what modifiers were seen.
346 (parse_var_assignment): New function to parse variable assignments.
347 (eval): Call the new function. Handle variable assignments earlier.
349 * variable.c (parse_variable_definition): Only parse; don't create var.
350 (assign_variable_definition): Call parse, then create the var.
352 2009-05-24 Paul Smith <psmith@gnu.org>
354 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
355 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
357 2009-03-14 Eli Zaretskii <eliz@gnu.org>
359 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
360 Fixes Savannah bug #25412.
362 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
363 prototype for xmalloc.
364 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
365 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
366 Loop over an array of extensions, instead of duplicating the same
367 code inline. Use SearchPath followed by CreateFile, instead of
368 the obsolete OpenFile. Fixes Savannah bug #17277.
369 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
370 to `find_file'. Fixes Savannah bug #25662.
372 2009-03-07 Eli Zaretskii <eliz@gnu.org>
374 * function.c (func_shell): Don't close pipedes[1] if it is -1.
375 Fixes Savannah bug #20495.
377 2009-02-28 Ralf Wildenhues <address@hidden>
379 * doc/make.texi (Instead of Execution): Document interaction of
380 -t with phony targets.
382 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
384 Introduce a new keyword "private" which applies to target-specific
385 variables and prevents their values from being inherited.
387 * variable.h (struct variable): Add private_var flag to each variable.
388 Add a flag to specify which list entry switches to the parent target.
389 * variable.c (define_variable_in_set): Initialize private_var flag.

423 * README.W32.template: Remove obsolete text about non-support for
424 -jN without Unixy shell. Remove obsolete text about not supplying
425 Visual Studio project files (we do supply them). Modify text to
426 prefer GCC builds to MSC builds.
428 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
430 * doc/make.texi (Empty Targets): Fix typo.

445 `value' field is NULL.
447 2007-12-22 Eli Zaretskii <eliz@gnu.org>
449 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
451 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
452 (TEXINFOS): Value changed to `doc/make.texi'.
453 (.SUFFIXES): Use .texi instead of .texinfo.
454 (make.info, make.dvi): Depend on doc/make.texi.
455 (.texi.info): New target, instead of ".texinfo.info". Change -I
456 switch to $(MAKEINFO) to look in doc/. Use --no-split.
457 (.texi): New target, instead of ".texinfo". Change -I switch to
458 $(MAKEINFO) to look in doc/. Use --no-split.
459 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
460 switch to $(MAKEINFO) to look in doc/.
461 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and

463 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
464 (html, make_1.html): New targets.
465 (.PHONY): Add "html".
466 (.SUFFIXES): Add .html.
468 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
470 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
471 HAVE_DECL_SYS_SIGLIST.
473 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
474 build does not use child_execute_job.
476 * variable.c (define_automatic_variables) [__MSDOS__]: Always
477 export the SHELL environment variable to the child.
479 2007-12-22 Eli Zaretskii <eliz@gnu.org>
481 * config.h.W32: Include sys/types.h.
482 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

485 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
488 2007-11-04 Paul Smith <psmith@gnu.org>
490 * doc/make.texi: Convert references to "commands", "command
491 lines", and "command script" to "recipe".
493 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:

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

533 * doc/make.texi (Special Variables): Moved this into the "How to
534 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

536 "Special Variables" section.
537 (Rule Introduction): Reference .RECIPEPREFIX.
538 (Simple Makefile): Ditto.

543 2007-09-10 Paul Smith <psmith@gnu.org>
545 * commands.c (print_commands): Don't print an extra line in the
546 command scripts. Prefix the command scripts with cmd_prefix, not \t.
548 * read.c (construct_include_path): Add the full string to the cache; we
549 were chopping the last char.
551 * NEWS: Announce the .RECIPEPREFIX special variable.
552 * variable.c (lookup_special_var): Rename from handle_special_var().
553 (lookup_variable): Call the new name.

558 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
559 * main.c (main): Create the .RECIPEPREFIX special variable.
560 * read.c (eval): Remove the cmd_prefix characters from the command
561 scripts here, so they're not stored in the commands array at all,
562 rather than waiting and stripping them out during command construction.
563 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
565 2007-08-15 Paul Smith <psmith@gnu.org>
567 * doc/make.texi (GNU Free Documentation License): The fdl.texi
568 file has had the section info removed, so add some to make.texi

571 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
573 * remake.c (check_dep): Reset the target state for intermediate
574 files. They might have been considered before but not updated

589 2007-07-13 Paul Smith <psmith@gnu.org>
591 * file.c (expand_deps): Use variable_buffer as the start of the
592 buffer, not the original pointer (in case it was reallocated).
593 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
594 Fixes Savannah bug #20452.
596 2007-07-04 Paul Smith <psmith@gnu.org>

631 Dave Korn <dave.korn@artimi.com>
633 2007-05-08 Paul Smith <psmith@gnu.org>
635 Fix Savannah bug #19656:
637 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
639 * make.h: Change all case-insensitive string compares to use
640 strcasecmp() (from POSIX). If we don't have that but do have one
641 of the others, define strcasecmp to be one of those instead. If
642 we don't have any, declare a prototype for our own version.
644 * misc.c (strcasecmp): Use this if we can't find any native
645 case-insensitive string comparison function.
646 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
647 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
649 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
650 strcasecmp() instead of stricmp().
651 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
652 instead of strcmpi().
653 * acinclude.m4: Remove the strcasecmp() check from here.
655 2007-03-21 Paul Smith <psmith@gnu.org>
657 * configure.in: Don't turn on case-insensitive file system support
658 if --disable-... is given. Fixes Savannah bug #19348.
660 2007-03-19 Paul Smith <psmith@gnu.org>
662 * ALL: Use the strcache for all file name strings, or other
663 strings which we will never free. The goal is to save memory by
664 avoiding duplicate copies of strings. However, at the moment this
665 doesn't save much memory in most situations: due to secondary
666 expansion we actually save prerequisite lists twice (once before
667 the secondary expansion, and then again after it's been parsed
668 into individual file names in the dep list). We will resolve this
669 in a future change, by doing the parsing up-front for targets
670 where secondary expansion is not set.
672 Moving things into the strcache also allows us to use const
673 pointers in many more places.
675 2007-01-03 Paul Smith <psmith@gnu.org>
677 * make.h (ENULLLOOP): Reset errno after each failed invocation of
678 the function, not just the first. Fixes Savannah bug #18680.
680 2006-11-18 Paul Smith <psmith@gnu.org>
682 * strcache.c (strcache_add_len): Don't allocate a new buffer
683 unless the string is not already nil-terminated. Technically this
684 is a violation of the standard, since we may be passed an array
685 that is not long enough to test one past. However, in make this
686 is never true since we only use nil-terminated strings or
689 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
691 * main.c: New global cmd_prefix, defaults to '\t'.
692 * job.c (construct_command_argv_internal): Use cmd_prefix instead
696 (dir_contents_file_exists_p): Check for an error return from
697 readdir(), just in case.
699 * commands.c: Constified.
700 * default.c: Constified.
701 * expand.c: Constified.
702 * function.c: Partial constification.
703 * variable.c: Partial constification.

707 * w32/pathstuff.c: Partial constification.
709 2006-11-16 Eli Zaretskii <eliz@gnu.org>
711 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
712 backslashes and drive letters as absolute.
714 2006-10-22 Paul Smith <psmith@gnu.org>
716 * main.c (struct command_switch): Use const and void*.
718 2006-10-21 Paul Smith <psmith@gnu.org>
721 * arscan.c: Constified.
723 2006-09-30 Paul Smith <psmith@gnu.org>
725 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
726 point to lastword since the example was updated.
727 Fixes Savannah bug #16304.
728 (Secondary Expansion): Correct example description.
729 Fixes Savannah bug #16468.
730 (Makefile Contents): Clarify that comments cannot appear within
731 variable references or function calls.
732 Fixes Savannah bug #16577.
733 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
734 Fixes Savannah bug #17701.
735 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
736 (Prerequisite Types): Added an example of using order-only
737 prerequisites. Fixes Savannah bug #17880.
738 (Rule Syntax): "lise" -> "list"
739 (Multiple Rules): ... -> @dots{}

779 * README.cvs: Add a reminder to notify the GNU translation robot.
781 * doc/make.texi: Change @direcategory (requested by Karl Berry).
783 2006-04-20 Paul D. Smith <psmith@gnu.org>
785 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
786 that don't have extended grep.
787 (cvsclean): Use $(PERL) instead of perl.
789 2006-04-09 Paul D. Smith <psmith@gnu.org>
791 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
793 * expand.c, implicit.c, main.c, read.c: Rename variables so that
794 inner-scope variables don't mask outer-scope variables.

852 with lastslash, since the latter points to filename, not to
854 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
855 Declare and define sh_chars_sh[].
857 2006-03-23 Paul D. Smith <psmith@gnu.org>
859 * configure.in: Look for build.sh.in in $srcdir so it will be
860 built for remote configurations as well.

863 Fixes Savannah bug #16166.
865 * misc.c (log_access): Takes a const char *.
866 * function.c (fold_newlines): Takes an unsigned int *.

901 (free_dep_chain): Use free_dep.
902 * read.c (record_files): Store stem in the dependency line.
903 * file.c (expand_deps): Use stem stored in the dependency line. Use
904 free_dep_chain instead of free_ns_chain.

917 Fixes Savannah bug #15913.
919 2006-03-09 Paul Smith <psmith@gnu.org>
921 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
922 listed non-existent files as changed. Turns out there's a bug in
923 the Linux kernel builds which means that this change causes
924 everything to rebuild every time. We will re-introduce this fix
925 in the next release, to give them time to fix their build system.
926 Fixes Savannah bug #16002.
927 Introduces Savannah bug #16051.

944 2006-02-19 Paul D. Smith <psmith@gnu.org>
946 * commands.c (set_file_variables): Realloc, not malloc, the static
947 string values to avoid memory leaks.
949 * expand.c (recursively_expand_for_file): Only set reading_file to
950 an initialized value.
952 * implicit.c (pattern_search): We need to make a copy of the stem
953 if we get it from an intermediate dep, since those get freed.

957 (enter_file) [VMS]: Ditto.

964 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
965 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
966 the calls to _beginthreadex.
968 * expand.c (recursively_expand_for_file): Initialize `save' to
969 prevent compiler warnings.
971 2006-02-18 Eli Zaretskii <eliz@gnu.org>

974 script/batch file if we are under -n. Call _setmode to switch the
975 script file stream to text mode.

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

986 2006-02-15 Paul D. Smith <psmith@gnu.org>
988 Fix for Savannah bug #106.
990 * expand.c (expanding_var): Keep track of which variable we're
991 expanding. If no variable is being expanded, it's the same as
993 * make.h (expanding_var): Declare it.
994 * expand.c (recursively_expand_for_file): Set expanding_var to the
995 current variable we're expanding, unless there's no file info in
996 it (could happen if it comes from the command line or a default
997 variable). Restore it before we exit.

1010 empty string we still need to free the allocated buffer.
1012 * implicit.c (pattern_search): If we allocated a variable set for
1013 an impossible file, free it.
1014 * variable.c (free_variable_set): New function.
1015 * variable.h: Declare it.
1017 * read.c (read_all_makefiles): Makefile names are kept in the
1018 strcache, so there's never any need to alloc/free them.

1022 archive support is enabled.

1037 A new internal capability: the string cache is a read-only cache
1038 of strings, with a hash table interface for fast lookup. Nothing
1039 in the cache will ever be freed, so there's no need for reference
1040 counting, etc. This is the beginning of a full solution for
1041 Savannah bug #15182, but for now we only store makefile names here.
1043 * strcache.c: New file. Implement a read-only string cache.
1044 * make.h: Add prototypes for new functions.

1052 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1053 directory time stamp didn't change, except on FAT filesystems.

1078 -W, don't overwrite it with the real mtime.
1079 Fixes Savannah bug #15341.
1081 Updates from Markus Mauhart <qwe123@chello.at>:
1083 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1084 (process_signal, process_last_err, process_exit_code): Manage
1085 invalid handle values.
1086 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1087 manage invalid handles; remove them.
1088 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1089 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1090 * README.cvs: Updates for building from CVS.
1092 2006-02-05 Paul D. Smith <psmith@gnu.org>
1094 * file.c (enter_file): Keep track of the last double_colon entry,
1095 to avoid walking the list every time we want to add a new one.
1096 Fixes Savannah bug #15533.
1097 * filedef.h (struct file): Add a new LAST pointer.
1099 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1100 the comparison. For 64-bits systems the result of the subtraction
1101 might not fit into an int. Use comparison instead.
1102 Fixes Savannah bug #15534.
1104 * doc/make.texi: Update the chapter on writing commands to reflect
1105 the changes made in 3.81 for backslash/newline and SHELL handling.
1107 2006-02-01 Paul D. Smith <psmith@gnu.org>
1109 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1110 variable st is not used when it's not initialized.

1123 * prepare_w32.bat: Remove this file from the distribution.
1125 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1127 * remake.c (update_goal_chain): Set g->changed instead of
1128 incrementing it, as it is only 8-bit wide, and could overflow if
1129 many commands got started in update_file.
1131 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1133 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1134 MAXIMUM_WAIT_OBJECTS.
1135 (process_wait_for_any_private): Change dimension of handles[]
1136 array to MAXIMUM_WAIT_OBJECTS.
1137 (process_used_slots): New function.
1138 (process_register): Don't register more processes than the
1139 available number of slots.
1140 (process_easy): Don't start new processes if all slots are used up.
1142 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1143 are already more children than sub_proc.c can handle, behave as if
1144 the load were too high.
1145 (start_job_command): Fix a typo in error message when process_easy
1148 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1150 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1151 the shell is not sh.exe.
1153 * job.c (create_batch_file): Renamed from create_batch_filename;
1154 all callers changed. Don't close the temporary file; return its
1155 file descriptor instead. New arg FD allows to return the file
1157 (construct_command_argv_internal): Use _fdopen instead of fopen to
1158 open the batch file.
1160 2006-01-04 Paul D. Smith <psmith@gnu.org>
1162 * readme.vms: Updates for case-insensitive VMS file systems from
1163 Hartmut Becker <Hartmut.Becker@hp.com>.
1164 * dir.c (vms_hash): Ditto.
1165 * vmsify.c (copyto): Ditto.
1166 * vmsfunctions.c (readdir): Ditto.
1168 * make.1: Add a section on the exit codes for make.
1170 * doc/make.texi: A number of minor updates to the documentation.
1172 2006-01-03 Paul D. Smith <psmith@gnu.org>
1174 * remake.c (update_file_1): Mark a prerequisite changed if it
1177 * read.c (eval): Be sure to strip off trailing whitespace from the
1178 prerequisites list properly. Also, initialize all fields in
1179 struct dep when creating a new one.
1181 2005-12-28 Paul D. Smith <psmith@gnu.org>
1183 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1184 disable warnings for MSC.
1185 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1187 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1189 * doc/make.texi (Execution): Add a footnote about changes in
1190 handling of backslash-newline sequences. Mention the differences
1191 on MS-DOS and MS-Windows.
1193 * NEWS: More details about building the MinGW port and a pointer
1194 to README.W32. Fix the section name that describes the new
1195 backward-incompatible processing of backslash-newline sequences.
1196 The special processing of SHELL set to "cmd" is only relevant to
1197 MS-Windows, not MS-DOS.
1199 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1201 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1202 to DWORD, to avoid compiler warnings.
1203 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1204 use %ld in format, to avoid compiler warnings.
1206 * doc/make.texi (Special Targets): Fix a typo.
1207 (Appending): Fix cross-reference to Setting.
1208 (Special Variables, Secondary Expansion, File Name Functions)
1209 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1210 periods after a sentence.
1211 (Execution): Add @: after "e.g.".
1212 (Environment): Fix punctuation.
1213 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1214 (Shell Function, Target-specific): Add @: after "vs."
1216 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1218 * read.c (record_target_var): Initialize variable's export field
1219 with v_default instead of leaving it "initialized" by whatever
1220 garbage happened to be on the heap.
1222 2005-12-12 Paul D. Smith <psmith@gnu.org>
1224 * make.1: Fix some display errors and document all existing options.
1225 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1227 2005-12-11 Paul D. Smith <psmith@gnu.org>
1229 * implicit.c (pattern_search): If 2nd expansion is not set for
1230 this implicit rule, replace the pattern with the stem directly,
1231 and don't re-expand the variable list. Along with the other
1232 .SECONDEXPANSION changes below, fixes bug #13781.
1234 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1236 * implicit.c (pattern_search): Mark other files that this rule
1237 builds as targets so that they are not treated as intermediates
1238 by the pattern rule search algorithm. Fixes bug #13022.
1240 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1242 * remake.c (notice_finished_file): Propagate the change of
1243 modification time to all the double-colon entries only if
1244 it is the last one to be updated. Fixes bug #14334.
1246 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1248 * function.c (func_flavor): Implement the flavor function which
1249 returns the flavor of a variable.
1250 * doc/make.texi (Functions for Transforming Text): Document it.
1251 * NEWS: Add it to the list of new functions.
1253 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1255 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1257 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1258 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1260 2005-10-26 Paul Smith <psmith@gnu.org>
1262 * read.c (record_files): Don't set deps flags if there are no deps.
1263 * maintMakefile: We only need to build the templates when we are
1264 creating a distribution, so don't do it for "all".
1266 2005-10-24 Paul D. Smith <psmith@gnu.org>
1268 Make secondary expansion optional: its enabled by declaring the
1269 special target .SECONDEXPANSION.
1271 * NEWS: Update information on second expansion capabilities.
1272 * doc/make.texi (Secondary Expansion): Document the
1273 .SECONDEXPANSION special target and its behavior.
1274 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1275 prerequisite list was found in a static pattern rule.
1276 (free_dep_chain): Declare a prototype.
1277 * file.c (parse_prereqs): New function: break out some complexity
1279 (expand_deps): If we aren't doing second expansion, replace % with
1280 the stem for static pattern rules. Call the new function.
1281 * filedef.h (parse_prereqs): Declare a prototype.
1282 * implicit.c (pattern_search): Initialize the new staticpattern
1284 * main.c (second_expansion): Declare a global variable to remember
1285 if the special target has been seen. Initialize the new
1286 staticpattern field for prerequisites.
1287 * make.h: Extern for second_expansion.
1288 * misc.c (free_dep_chain): New function: frees a struct dep list.
1289 * read.c (read_all_makefiles): Initialize the staticpattern field.
1290 (eval_makefile): Ditto.
1291 (record_files): Check for the .SECONDEXPANSION target and set
1292 second_expansion global if it's found.
1293 Use the new free_dep_chain() instead of doing it by hand.
1294 Set the staticpattern field for prereqs of static pattern targets.
1296 2005-10-16 Paul D. Smith <psmith@gnu.org>
1298 * main.c (main): Set CURDIR to be a file variable instead of a
1299 default, so that values of CURDIR inherited from the environment
1300 won't override the make value.
1302 2005-09-26 Paul D. Smith <psmith@gnu.org>
1304 * job.c (construct_command_argv_internal): If the line is empty
1305 remember to free the temporary argv strings.
1308 2005-09-16 Paul D. Smith <psmith@gnu.org>
1310 * job.c (start_job_command): The noerror flag is a boolean (single
1311 bit); set it appropriately.
1312 Reported by Mark Eichin <eichin@metacarta.com>
1314 2005-08-29 Paul D. Smith <psmith@gnu.org>
1316 * function.c (func_error): On Windows, output from $(info ...)
1317 seems to come in the wrong order. Try to force it with fflush().
1319 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1321 * read.c (record_files): Move code that sets stem for static
1322 pattern rules out of the if (!two_colon) condition so it is
1323 also executed for two-colon rules. Fixes Savannah bug #13881.
1325 2005-08-08 Paul D. Smith <psmith@gnu.org>
1327 * make.h: Don't test that __STDC__ is non-0. Some compilers
1328 (Windows for example) set it to 0 to denote "ISO C + extensions".
1331 2005-08-07 Paul D. Smith <psmith@gnu.org>
1333 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1334 conditional (slightly different version of a fix from Eli).
1336 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1337 If make is running in parallel without -k and two jobs die in a
1338 row, but not too close to each other, then make will quit without
1339 waiting for the rest of the jobs to die.
1341 * main.c (die): Don't reset err before calling reap_children() the
1342 second time: we still want it to be in the error condition.
1343 * job.c (reap_children): Use a static variable, rather than err,
1344 to control whether or not the error message should be printed.
1346 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1348 * w32/subproc/sub_proc.c: Include signal.h.
1349 (process_pipe_io, process_file_io): Pass a pointer to a local
1350 DWORD variable to GetExitCodeProcess. If the exit code is
1351 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1353 * job.c [WINDOWS32]: Include windows.h.
1354 (main_thread) [WINDOWS32]: New global variable.
1355 (reap_children) [WINDOWS32]: Get the handle for the main thread
1356 and store it in main_thread.
1358 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1359 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1360 doing anything else. When we are done, close the main thread
1361 handle and exit with status 130.
1363 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1365 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1368 * main.c (find_and_set_default_shell): If found a DOSish shell,
1369 set sh_found and the value of default_shell, and report the
1370 findings in debug mode.
1372 * job.c (construct_command_argv_internal): Check unixy_shell, not
1373 no_default_sh_exe, to decide whether to use Unixy or DOSish
1376 * README.W32: Update with info about the MinGW build.
1378 * build_w32.bat: Support MinGW.
1380 * w32/subproc/build.bat: Likewise.
1382 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1383 printing DWORD args.
1385 * function.c (windows32_openpipe): Fix format strings for printing
1388 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1390 (start_job_command): Fix format string for printing the result of
1392 (start_job_command) [WINDOWS32]: Do not define.
1393 (exec_command): Fix format string for printing HANDLE args.
1395 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1396 to avoid compiler warnings.
1397 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1398 (Note: some of these fixes were submitted independently by J. Grant)
1400 2005-07-30 J. Grant <jg@jguk.org>
1402 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1403 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1404 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1406 2005-07-15 Paul Smith <psmith@gnu.org>
1408 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1409 we don't have a POSIX shell, then revert to the old
1410 backslash-newline behavior (where they are stripped).
1413 2005-07-08 Paul D. Smith <psmith@gnu.org>
1415 * config.h.W32.template: Reorder to match the standard config.h,
1416 for easier comparisons.
1417 From J. Grant <jg@jguk.org>
1419 * maintMakefile: Remove .dep_segment before overwriting it, in
1420 case it's not writable or noclobber is set.
1421 * expand.c (variable_expand_string): Cast result of pointer
1422 arithmetic to avoid a warning.
1423 * main.c (switches): Add full-fledged final initializer.
1425 2005-07-06 Paul D. Smith <psmith@gnu.org>
1427 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1428 * signame.c (strsignal): If we found _sys_siglist[] or
1429 __sys_siglist[] use those instead of sys_siglist[].
1430 From Albert Chin <china@thewrittenword.com>
1432 2005-07-04 Paul D. Smith <psmith@gnu.org>
1434 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1435 globfree(); set up to use the GNU versions.
1436 From Martin Zinser <zinser@zinser.no-ip.info>
1438 2005-07-03 Paul D. Smith <psmith@gnu.org>
1440 From J. Grant <jg@jguk.org>:
1442 * README.W32.template: Update the Windows and tested MSVC versions.
1443 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1444 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1445 * build_w32.bat: Ditto.
1446 * w32/subproc/build.bat: Ditto.
1448 2005-06-28 Paul D. Smith <psmith@gnu.org>
1450 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1451 declaration was checked but not present.
1453 2005-06-27 Paul D. Smith <psmith@gnu.org>
1455 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1456 to unsigned long. Fixes Savannah bug #13550.
1458 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1459 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1460 Fixes Savannah bug #13551.
1462 2005-06-26 Paul D. Smith <psmith@gnu.org>
1464 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1465 it if ANSI_STRING is not set.
1467 2005-06-25 Paul D. Smith <psmith@gnu.org>
1469 * read.c (eval): If no filenames are passed to any of the
1470 "include" variants, don't print an error.
1471 * doc/make.texi (Include): Document this.
1472 Fixes Savannah bug #1761.
1474 * job.c (construct_command_argv_internal): Sanitize handling of
1475 backslash/newline pairs according to POSIX: that is, keep the
1476 backslash-newline in the command script, but remove a following
1477 TAB character, if present. In the fast path, make sure that the
1478 behavior matches what the shell would do both inside and outside
1479 of quotes. In the slow path, quote the backslash and put a
1480 literal newline in the string.
1481 Fixes Savannah bug #1332.
1482 * doc/make.texi (Execution): Document the new behavior and give
1484 * NEWS: Make a note of the new behavior.
1486 * make.h [WINDOWS32]: #include <direct.h>.
1487 Fixes Savannah bug #13478.
1489 * remake.c (name_mtime): If the stat() of a file fails and the -L
1490 option was given and the file is a symlink, take the best mtime of
1491 the symlink we can get as the mtime of the file and don't fail.
1492 Fixes Savannah bug #13280.
1494 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1495 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1496 inside a variable reference. Make this function static as it's
1498 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1499 parsing an unexpanded line looking for semicolons.
1500 Fixes Savannah bug #1454.
1501 * misc.c (remove_comments): Move this to read.c and make it static
1502 as it's only used there. Call find_char_unquote() with new arg.
1503 * make.h: Remove prototypes for find_char_unquote() and
1504 remove_comments() since they're static now.
1506 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1507 its export flag and obtain its value. When we need to re-exec,
1508 increment the value and add it into the environment.
1509 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1510 * NEWS: Mention MAKE_RESTARTS.
1511 * main.c (always_make_set): New variable. Change the -B option to
1512 set this one instead.
1513 (main): When checking makefiles, only set always_make_flag if
1514 always_make_set is set AND the restarts flag is 0. When building
1515 normal targets, set it IFF always_make_set is set.
1516 (main): Avoid infinite recursion with -W, too: only set what-if
1517 files to NEW before we check makefiles if we've never restarted
1518 before. If we have restarted, set what-if files to NEW _after_ we
1520 Fixes Savannah bug #7566:
1522 2005-06-17 Paul D. Smith <psmith@gnu.org>
1524 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1525 in the prerequisites list.
1527 2005-06-12 Paul D. Smith <psmith@gnu.org>
1529 Fix Savannah bug # 1328.
1531 * configure.in: Check for atexit().
1532 * misc.c (close_stdout): Test stdout to see if writes to it have
1533 failed. If so, be sure to exit with a non-0 error code. Based on
1534 code found in gnulib.
1535 * make.h: Prototype.
1536 * main.c (main): Install close_stdout() with atexit().
1538 2005-06-10 Paul D. Smith <psmith@gnu.org>
1540 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1542 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1543 headers; make vmsWaitForChildren() static; extern vmsify().
1544 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1545 Don't create child_execute_job() here (it's in vmsjobs.c).
1546 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1548 2005-06-09 Paul D. Smith <psmith@gnu.org>
1550 * variable.c (push_new_variable_scope): File variables point
1551 directly to the global_setlist variable. So, inserting a new
1552 scope in front of that has no effect on those variables: they
1553 don't go through current_variable_set_list. If we're pushing a
1554 scope and the current scope is global, push it "the other way" so
1555 that the new setlist is in the global_setlist variable, and
1556 next points to a new setlist with the global variable set.
1557 (pop_variable_scope): Properly undo a push with the new
1559 Fixes Savannah bug #11913.
1561 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1563 * job.c (reap_children): Don't die of the command failed but
1564 the dontcare flag is set. Fixes Savannah bug #13216.
1566 * implicit.c (pattern_search): When creating a target from
1567 an implicit rule match, lookup pattern target and set precious
1568 flag in a newly created target. Fixes Savannah bug #13218.
1570 2005-05-13 Paul D. Smith <psmith@gnu.org>
1572 Implement "if... else if... endif" syntax.
1574 * read.c (eval): Push all checks for conditional words ("ifeq",
1575 "else", etc.) down into the conditional_line() function.
1576 (conditional_line): Rework to allow "else if..." clause. New
1577 return value -2 for lines which are not conditionals. The
1578 ignoring flag can now also be 2, which means "already parsed a
1579 true branch". If that value is seen no other branch of this
1580 conditional can be considered true. In the else parsing if there
1581 is extra text after the else, invoke conditional_line()
1582 recursively to see if it's another conditional. If not, it's an
1583 error. If so, raise the conditional value to this level instead
1584 of creating a new conditional nesting level. Special check for
1585 "else" and "endif", which aren't allowed on the "else" line.
1586 * doc/make.texi (Conditional Syntax): Document the new syntax.
1588 2005-05-09 Paul D. Smith <psmith@gnu.org>
1590 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1591 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1592 recurses to the w32 directory, even on non-Windows systems. Use
1593 the method suggested in the automake manual.
1594 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1595 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1597 2005-05-07 Paul D. Smith <psmith@gnu.org>
1599 * main.c (die): If we're dying with a fatal error (not that a
1600 command has failed), write back any leftover tokens before we go.
1602 * job.c (set_child_handler_action_flags): If there are jobs
1603 waiting for the load to go down, set an alarm to go off in 1
1604 second. This allows us to wake up from a potentially long-lasting
1605 read() and start a new job if the load has gone down. Turn it off
1607 (job_noop): Dummy signal handler function.
1608 (new_job): Invoke it with the new semantics.
1610 * docs/make.texi: Document secondary expansion. Various cleanups
1613 2005-05-03 Paul D. Smith <psmith@gnu.org>
1615 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1616 the targets which are to ultimately be made are called "goals";
1617 see the GNU make manual. Also, MAKECMDGOALS, etc.
1619 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1620 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1621 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1623 2005-05-02 Paul D. Smith <psmith@gnu.org>
1625 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1626 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1627 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1628 functions to vmsjobs.c. #include it into jobs.c.
1630 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1631 jobserver tokens. I found that this happens when an exported
1632 recursive variable contains a $(shell ...) function reference: in
1633 this situation we could "forget" to write back a token.
1635 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1636 we have. It's not reliable to depend on the number of children in
1637 our linked list so keep a separate count.
1638 (new_job): Check jobserver_tokens rather than children &&
1639 waiting_jobs. Increment jobserver_tokens when we get one.
1640 (free_child): If jobserver_tokens is 0, internal error. If it's
1641 >1, write a token back to the jobserver pipe (we don't write a
1642 token for the "free" job). Decrement jobserver_tokens.
1644 * main.c: Add variable master_job_slots.
1645 (main): Set it to hold the number of jobs requested if we're the
1646 master process, when using the jobserver.
1647 (die): Sanity checks: first test jobserver_tokens to make sure
1648 this process isn't holding any tokens we didn't write back.
1649 Second, if master_job_slots is set count the tokens left in the
1650 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1652 2005-04-24 Paul D. Smith <psmith@gnu.org>
1654 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1655 with -l# can lose jobserver tokens, because waiting jobs are not
1656 consulted properly when checking for the "free" token.
1658 * job.c (free_child): Count waiting_jobs as having tokens.
1659 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1660 handle jobs waiting for the load to drop.
1662 2005-04-23 Paul D. Smith <psmith@gnu.org>
1664 * main.c (main): Be careful to not core if a variable setting in
1665 the environment doesn't contain an '='. This is illegal but can
1666 happen in broken setups.
1667 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1669 2005-04-12 Paul D. Smith <psmith@gnu.org>
1671 The second expansion feature causes significant slowdown. Timing
1672 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1673 read the makefile before the feature, to 11+s to do the same
1674 operations after the feature. Additionally, memory usage
1675 increased drastically. To fix this I added some intelligence that
1676 avoids the overhead of the second expansion unless it's required.
1678 * dep.h: Add a new boolean field, need_2nd_expansion.
1680 * read.c (eval): When creating the struct dep for the target,
1681 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1682 (record_files): If there's a "%" in a static pattern rule, it gets
1683 converted to "$*" so set need_2nd_expansion to 1.
1685 * file.c (expand_deps): Rework to be more efficient. Only perform
1686 initialize_file_variables(), set_file_variables(), and
1687 variable_expand_for_file() if the need_2nd_expansion is set.
1689 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1690 (pattern_search): Ditto.
1691 * main.c (handle_non_switch_argument): Ditto.
1693 * read.c (read_all_makefiles): Ditto.
1694 (eval_makefile): Ditto.
1696 2005-04-07 Paul D. Smith <psmith@gnu.org>
1698 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1699 * variable.c (sync_Path_environment): Ditto.
1700 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1702 * main.c (main): Define the .FEATURES variable.
1703 * NEWS: Announce .FEATURES.
1704 * doc/make.texi (Special Variables): Document .FEATURES.
1706 * remake.c (check_dep): If a file is .PHONY, update it even if
1707 it's marked intermediate. Fixes Savannah bug #12331.
1709 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1711 * file.c (expand_deps): Factor out the second expansion and
1712 prerequisite line parsing logic from snap_deps().
1714 * file.c (snap_deps): Use expand_deps(). Expand and parse
1715 prerequisites of the .SUFFIXES special target first. Fixes
1716 Savannah bug #12320.
1718 2005-03-13 Paul D. Smith <psmith@gnu.org>
1720 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1723 2005-03-11 Paul D. Smith <psmith@gnu.org>
1725 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1726 available, not undefined (from Earnie Boyd).
1728 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1730 * implicit.c (pattern_search): Mark an intermediate target as
1731 precious if it happened to be a prerequisite of some (other)
1732 target. Fixes Savannah bug #12267.
1734 2005-03-09 Paul D. Smith <psmith@gnu.org>
1736 * read.c (eval_makefile): Add alloca(0).
1737 (eval_buffer): Ditto.
1739 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1741 * main.c (main): Use o_file instead of o_default when defining
1742 the .DEFAULT_TARGET special variable.
1743 * read.c (eval): Use define_variable_global() instead of
1744 define_variable() when setting new value for the .DEFAULT_TARGET
1745 special variable. Fixes Savannah bug #12266.
1747 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1749 * imlicit.c (pattern_search): Mark files for which an implicit
1750 rule has been found as targets. Fixes Savannah bug #12202.
1752 2005-03-04 Paul D. Smith <psmith@gnu.org>
1755 * doc/make.texi (Automatic Variables): Document $|.
1757 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1759 * read.c (record_files): Instead of substituting % with
1760 actual stem value in dependency list replace it with $*.
1761 This fixes stem triple expansion bug.
1763 * implicit.c (pattern_search): Copy stem to a separate
1764 buffer and make it a properly terminated string. Assign
1765 this buffer instead of STEM (which is not terminated) to
1766 f->stem. Instead of substituting % with actual stem value
1767 in dependency list replace it with $*. This fixes stem
1768 triple expansion bug.
1770 2005-03-01 Paul D. Smith <psmith@gnu.org>
1772 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1773 on Windows, as it takes a handle not a pid. Just exit.
1774 Fix from patch #3679, provided by Alessandro Vesely.
1776 * configure.in: Update check for sys_siglist[] from autoconf manual.
1777 * signame.c (strsignal): Update to use the new autoconf macro.
1779 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1781 * read.c (record_files): Add a check for the list of prerequisites
1782 of a static pattern rule being empty. Fixes Savannah bug #12180.
1784 2005-02-28 Paul D. Smith <psmith@gnu.org>
1786 * doc/make.texi (Text Functions): Update docs to allow the end
1787 ordinal for $(wordlist ...) to be 0.
1788 * function.c (func_wordlist): Fail if the start ordinal for
1789 $(wordlist ...) is <1. Matches documentation.
1790 Resolves Savannah support request #103195.
1792 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1793 previously we were stopping when !-q, exactly the opposite. This
1794 has been wrong since version 1.34, in 1994!
1795 (update_file): If we got an error don't break out to run more
1796 double-colon rules: just return immediately.
1797 Fixes Savannah bug #7144.
1799 2005-02-27 Paul D. Smith <psmith@gnu.org>
1801 * misc.c (end_of_token): Make argument const.
1802 * make.h: Update prototype.
1804 * function.c (abspath, func_realpath, func_abspath): Use
1805 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1806 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1807 * read.c (record_files): Ditto.
1808 * variable.c (do_variable_definition): Ditto.
1810 * function.c (func_error): Create a new function $(info ...) that
1811 simply prints the message to stdout with no extras.
1812 (function_table_init): Add new function to the table.
1813 * NEWS: Add $(info ...) reference.
1814 * doc/make.texi (Make Control Functions): Document it.
1816 New feature: if the system supports symbolic links, and the user
1817 provides the -L/--check-symlink-time flag, then use the latest
1818 mtime between the symlink(s) and the target file.
1820 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1821 readlink(). If both are available, define MAKE_SYMLINKS.
1822 * main.c: New variable: check_symlink_flag.
1823 (usage): Add a line for -L/--check-symlink-times to the help string.
1824 (switches): Add -L/--check-symlink-times command line argument.
1825 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1826 print a warning and disable it again.
1827 * make.h: Declare check_symlink_flag.
1828 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1829 if the file is a symlink then check each link in the chain and
1830 choose the NEWEST mtime we find as the mtime for the file. The
1831 newest mtime might be the file itself!
1832 * NEWS: Add information about this new feature.
1833 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1835 Avoid core dumps described in Savannah bug # 12124:
1837 * file.c: New variable snapped_deps remember whether we've run
1839 (snap_deps): Set it.
1840 * filedef.h: Extern it.
1841 * read.c (record_files): Check snapped_deps; if it's set then
1842 we're trying to eval a new target/prerequisite relationship from
1843 within a command script, which we don't support. Fatal.
1845 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1847 Implementation of the .DEFAULT_TARGET special variable.
1849 * read.c (eval): If necessary, update default_target_name when
1851 * read.c (record_files): Update default_target_file if
1852 default_target_name has changed.
1853 * main.c (default_target_name): Define.
1854 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1855 default_target_name is set use default_target_file as a root
1857 * filedef.h (default_target_name): Declare.
1858 * dep.h (free_dep_chain):
1859 * misc.c (free_dep_chain): Change to operate on struct nameseq
1860 and change name to free_ns_chain.
1861 * file.c (snap_deps): Update to use free_ns_chain.
1863 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1865 Implementation of the second expansion in explicit rules,
1866 static pattern rules and implicit rules.
1868 * read.c (eval): Refrain from chopping up rule's dependencies.
1869 Store them in a struct dep as a single dependency line. Remove
1870 the code that implements SySV-style automatic variables.
1872 * read.c (record_files): Adjust the code that handles static
1873 pattern rules to expand all percents instead of only the first
1874 one. Reverse the order in which dependencies are stored so that
1875 when the second expansion reverses them again they appear in
1876 the makefile order (with some exceptions, see comments in
1877 the code). Remove the code that implements SySV-style automatic
1880 * file.c (snap_deps): Implement the second expansion and chopping
1881 of dependency lines for explicit rules.
1883 * implicit.c (struct idep): Define an auxiliary data type to hold
1884 implicit rule's dependencies after stem substitution and
1887 * implicit.c (free_idep_chain): Implement.
1889 * implicit.c (get_next_word): Implement helper function for
1890 parsing implicit rule's dependency lines into words taking
1891 into account variable expansion requests. Used in the stem
1894 * implicit.c (pattern_search): Implement the second expansion
1895 for implicit rules. Also fixes bug #12091.
1897 * commands.h (set_file_variables): Declare.
1898 * commands.c (set_file_variables): Remove static specifier.
1900 * dep.h (free_dep_chain): Declare.
1901 * misc.c (free_dep_chain): Implement.
1903 * variable.h (variable_expand_for_file): Declare.
1904 * expand.c (variable_expand_for_file): Remove static specifier.
1906 * make.h (strip_whitespace): Declare.
1907 * function.c (strip_whitespace): Remove static specifier.
1909 2005-02-26 Paul D. Smith <psmith@gnu.org>
1911 * main.c (main): Check for ferror() when reading makefiles from stdin.
1912 Apparently some shells in Windows don't close pipes properly and
1915 2005-02-24 Jonathan Grant <jg@jguk.org>
1917 * configure.in: Add MinGW configuration options, and extra w32 code
1919 * Makefile.am: Add MinGW configuration options, and extra w32 code
1921 * main.c: Determine correct program string (after last \ without .exe).
1922 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1924 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1925 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1926 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1927 environment support.
1929 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1931 * function.c (func_shell): When initializing error_prefix, check
1932 that reading file name is not null. This fixes long-standing
1933 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1935 2005-02-09 Paul D. Smith <psmith@gnu.org>
1937 * maintMakefile: Update the CVS download URL to simplify them.
1938 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1939 downloading the .texi files from Savannah now.
1941 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1943 * main.c (handle_non_switch_argument): Only add variables to
1944 command_variables if they're not already there: duplicate settings
1945 waste space and can be confusing to read.
1947 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1948 this header is never included by non-WINDOWS32 code, and it
1949 requires <config.h> to define which isn't always included first.
1951 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1952 testing MINGW32 versions.
1954 * main.c (log_working_directory): flush stdout to be sure the WD
1955 change is printed before any stderr messages show up.
1957 2005-02-01 Paul D. Smith <psmith@gnu.org>
1959 * maintMakefile (po_repo): Update the GNU translation site URL.
1961 2004-12-01 Paul D. Smith <psmith@gnu.org>
1963 * main.c (main): Change char* env_shell to struct variable shell_var.
1964 * variable.c (target_environment): Use new shell_var.
1966 2004-11-30 Paul D. Smith <psmith@gnu.org>
1968 * configure.in: The old way we avoided creating build.sh from
1969 build.sh.in before build.sh.in exists doesn't work anymore; we
1970 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1971 the help!). This also keeps automake from complaining.
1972 * Makefile.am (README): Add a dummy target so automake won't
1973 complain that this file doesn't exist when we checkout from CVS.
1974 * maintMakefile (.dep_segment): Rewrite this rule since newer
1975 versions of automake don't provide DEP_FILES.
1977 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1979 Implementation of `realpath' and `abspath' built-in functions.
1981 * configure.in: Check for realpath.
1982 * function.c (abspath): Return an absolute file name that does
1983 not contain any `.' or `..' components, nor repeated `/'.
1984 * function.c (func_abspath): For each name call abspath.
1985 * function.c (func_realpath): For each name call realpath
1986 from libc or delegate to abspath if realpath is not available.
1987 * doc/make.texi (Functions for File Names): Document new functions.
1988 * doc/make.texi (Quick Reference): Ditto.
1990 2004-11-28 Paul D. Smith <psmith@gnu.org>
1992 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1993 arguments. Fixes bug #10252.
1995 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1997 * main.c (main): Set SHELL to v_noexport by default. Remember the
1998 original environment setting of SHELL in the env_shell variable.
1999 * main.h: Export new env_shell variable.
2000 * variable.c (target_environment): If we find a v_noexport
2001 variable for SHELL, add a SHELL variable with the env_shell value.
2002 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2003 * doc/make.texi (Variables/Recursion): Ditto.
2005 2004-11-28 Paul D. Smith <psmith@gnu.org>
2007 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2008 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2009 Patch by Alessandro Vesely.
2011 2004-11-12 Paul D. Smith <psmith@gnu.org>
2013 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2014 the command line if it's inside a string.
2015 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2017 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2019 * function.c (func_lastword): New function: return last word
2020 from the list of words.
2021 * doc/make.texi: Document $(lastword ). Fix broken links in
2022 Quick Reference section.
2024 2004-10-06 Paul D. Smith <psmith@gnu.org>
2026 Apply patch from Alessandro Vesely, provided with bug # 9748.
2027 Fix use of tmpnam() to work with Borland C.
2029 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2030 construction of a temporary filename, and call new function
2031 create_batch_filename().
2032 (create_batch_filename) [WINDOWS32]: New function to create a
2035 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2037 * read.c (record_target_var): Expand simple pattern-specific
2039 * variable.c (initialize_file_variables): Do not expand simple
2040 pattern-specific variable.
2042 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2044 * remake.c (update_file_1): When rebuilding makefiles inherit
2045 dontcare flag from a target that triggered update.
2047 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2049 * variable.c (initialize_file_variables): Mark pattern-specific
2050 variable as a per-target and copy export status.
2052 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2054 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2056 * implicit.c (pattern_search): When considering an implicit rule's
2057 prerequisite check that it is actually a target rather then
2058 just an entry in the file hashtable.
2060 2004-09-21 Paul D. Smith <psmith@gnu.org>
2062 * read.c (readstring): Fix some logic errors in backslash handling.
2063 (eval): Remove some unnecessary processing in buffer handling.
2064 (record_target_var): Assert that parse_variable_definition() succeeded.
2065 Reported by: Markus Mauhart <qwe123@chello.at>.
2067 * misc.c: Removed the sindex() function. All instances of this
2068 function were trivially replaceable by the standard strstr()
2069 function, and that function will always have better (or certainly
2070 no worse) performance than the very simple-minded algorithm
2071 sindex() used. This can matter with complex makefiles.
2072 * make.h: Remove the prototype for sindex().
2073 * function.c (subst_expand): Convert sindex() call to strstr().
2074 This means we no longer need to track the TLEN value so remove that.
2075 (func_findstring): Convert sindex() to strstr().
2076 * commands.c (chop_commands): Convert sindex() calls to strstr().
2077 Suggested by: Markus Mauhart <qwe123@chello.at>.
2079 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2080 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2081 If SHELL is set to CMD.EXE then assume it's batch-mode and
2082 non-unixy. I wrote the code differently from the patch, though,
2083 to make it safer. This also resolves bug #9174.
2085 2004-09-20 Paul D. Smith <psmith@gnu.org>
2087 * expand.c (variable_expand_string): Modify to invoke
2088 patsubst_expand() instead of subst_expand(); the latter didn't
2089 handle suffix patterns correctly.
2090 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2091 was used only from variable_expand_string() and is no longer used
2093 (func_subst): Ditto, on call to subst_expand().
2094 (patsubst_expand): Require the percent pointers to point to the
2095 character after the %, not to the % itself.
2096 * read.c (record_files): New call criteria for patsubst_expand().
2097 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2098 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2100 2004-09-19 Paul D. Smith <psmith@gnu.org>
2102 * function.c (subst_expand): Fix a check in by_word: look for a
2103 previous blank if we're beyond the beginning of the string, not
2104 the beginning of the word.
2105 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2107 2004-05-16 Paul D. Smith <psmith@gnu.org>
2109 * remake.c (update_goal_chain): Change the argument specifying
2110 whether we're rebuilding makefiles to be a global variable,
2111 REBUILDING_MAKEFILES.
2112 (complain): Extract the code that complains about no rules to make
2113 a target into a separate function.
2114 (update_file_1): If we tried to rebuild a file during the makefile
2115 rebuild phase and it was dontcare, then no message was printed.
2116 If we then try to build the same file during the normal build,
2117 print a message this time.
2118 (remake_file): Don't complain about un-remake-able files when
2119 we're rebuilding makefiles.
2121 2004-05-11 Paul D. Smith <psmith@gnu.org>
2123 * job.c (construct_command_argv_internal): OS/2 patches from
2124 Andreas Buening <andreas.buening@nexgo.de>.
2126 2004-05-10 Paul D. Smith <psmith@gnu.org>
2128 * remake.c (update_file): Don't walk the double-colon chain unless
2129 this is a double-colon rule. Fix suggested by Boris Kolpackov
2130 <boris@kolpackov.net>.
2132 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2133 * readme.vms: New section describing OpenVMS support and issues.
2134 * default.c (default_variables): Add support for IA64.
2135 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2136 without some privilege aborts make with the error
2137 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2138 pressing Ctrl+Y and the input device is no terminal. The change
2139 catches this error and just continues.
2141 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2143 2004-04-25 Paul D. Smith <psmith@gnu.org>
2145 * commands.c (set_file_variables): Set $< properly in the face of
2146 order-only prerequisites.
2147 Patch from Boris Kolpackov <boris@kolpackov.net>
2149 2004-04-21 Bob Byrnes <byrnes@curl.com>
2151 * main.c (main): Notice failures to remake makefiles.
2153 2004-03-28 Paul D. Smith <psmith@gnu.org>
2155 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2157 * job.c: No default shell for RISC OS.
2158 (load_too_high): Hard-code the return to 1.
2159 (construct_command_argv_internal): No sh_chars or sh_cmds.
2160 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2162 2004-03-20 Paul D. Smith <psmith@gnu.org>
2164 * variable.c (do_variable_definition): Don't append from the
2165 global set if a previous non-appending target-specific variable
2166 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2169 * expand.c (reference_variable): Don't give up on variables with
2170 no value that have the target-specific append flag set: they might
2171 have a value after all. Reported by Oliver Schmidt
2172 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2173 <nikulin@dx1cmd.inp.nsk.su>.
2175 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2176 refer to absolute pathnames in directories that don't exist: some
2177 portion of the makefile could create those directories before we
2178 match the pattern. Fixes bugs #775 and #108.
2180 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2182 * main.c (main): Free makefile_mtimes if we have any.
2183 * README.W32.template: Update documentation for the current status
2184 of the MS-Windows port.
2185 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2186 environment variable is sometimes already defined which causes the
2188 * main.c (debug_signal_handler): Only define this function if
2189 SIGUSR1 is available.
2191 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2193 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2194 * README.OS2.template: Documentation updates.
2195 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2196 link line for safety.
2197 * maintMakefile (build.sh.in): Remove an extraneous ")".
2198 * job.c (child_execute_job): Close saved FDs.
2199 * job.c (exec_command) [OS/2]: exec_command(): If the command
2200 can't be exec'ed and if the shell is not Unix-sh, then try again
2201 with argv = { "cmd", "/c", ... }. Normally, this code is never
2202 reached for the cmd shell unless the command really doesn't exist.
2203 (construct_command_argv_internal) [OS/2]: The code for cmd
2204 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2205 The CMD builtin commands are case insensitive so use strcasecmp().
2207 2004-03-19 Paul D. Smith <psmith@gnu.org>
2209 * read.c (do_define): Re-order line counter increment so the count
2210 is accurate (we were losing one line per define). Reported by
2211 Dave Yost <Dave@Yost.com>.
2213 2004-03-06 Paul D. Smith <psmith@gnu.org>
2215 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2217 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2218 * misc.c (message,error,fatal): Ditto.
2219 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2220 * config.h.W32.template: Ditto.
2221 * config.h-vms.template: Ditto.
2222 * config.ami.template: Ditto.
2224 2004-03-04 Paul D. Smith <psmith@gnu.org>
2226 * README.template: Add a note about broken /bin/sh on SunOS
2227 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2229 * misc.c (message, error, fatal): Don't use "..." if we're using
2230 varargs. ansi2knr should handle this but it doesn't work: it
2231 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2232 done. On many systems (SunOS for example) va_dcl is a #define.
2233 So, force the use of the non-"..." version on pre-ANSI compilers.
2235 * maintMakefile (sign-dist): Create some rules to help automate
2236 the new GNU ftp upload method.
2238 2004-02-24 Paul D. Smith <psmith@gnu.org>
2240 * config.h.W32.template: Add HAVE_STDARG_H
2241 * config.h-vms.template: Ditto.
2242 * config.ami.template: Ditto.
2244 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2246 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2247 * build_w32.bat: Remove extra "+".
2249 2004-02-23 Paul D. Smith <psmith@gnu.org>
2251 * make.h: Create an UNUSED macro to mark unused parameters.
2252 * (many): Clean up warnings by applying UNUSED, fixing
2253 signed/unsigned incompatibilities, etc.
2255 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2257 * filedef.h: Name the command_state enumeration.
2258 * file.c (set_command_state): Use the enumeration in the function
2261 * configure.in: Explicitly set SET_MAKE to empty, to disable
2262 MAKE=make even when no make already exists. Fix bug #3823.
2264 2004-02-22 Paul D. Smith <psmith@gnu.org>
2266 * maintMakefile: Perl script to clean up all non-CVS files. Use
2267 it on all the subdirectories for the cvs-clean target.
2269 * main.c (decode_switches): Require non-empty strings for all our
2270 string command-line options. Fixes Debian bug # 164165.
2272 * configure.in: Check for stdarg.h and varargs.h.
2273 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2274 for printing messages.
2275 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2280 A number of patches for OS/2 support from Andreas Buening
2281 <andreas.buening@nexgo.de>:
2283 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2284 disable the SIGCHLD handler.
2285 (reap_children) [OS/2]: Remove special handling of job_rfd.
2286 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2287 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2288 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2289 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2290 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2293 2004-02-21 Paul D. Smith <psmith@gnu.org>
2295 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2296 <mail@kristov.de> reports that if process_begin() fails we don't
2297 handle the error condition correctly in all cases.
2298 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2299 to have a newline on the message.
2301 * job.c (construct_command_argv_internal): Add "test" to UNIX
2302 sh_cmds[]. Fixes Savannah bug # 7606.
2304 2004-02-04 Paul D. Smith <psmith@gnu.org>
2306 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2307 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2308 Hartmut Becker <Hartmut.Becker@hp.com>.
2310 2004-01-21 Paul D. Smith <psmith@gnu.org>
2312 * job.c (load_too_high): Implement an algorithm to control the
2313 "thundering herd" problem when using -l to control job creation
2314 via the load average. The system only recomputes the load once a
2315 second but we can start many jobs in a second. To solve this we
2316 keep track of the number of jobs started in the last second and
2317 apply a weight to try to guess what a correct load would be.
2318 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2319 Also fixes bug #4693.
2320 (reap_children): Decrease the job count for this second.
2321 (start_job_command): Increase the job count for this second.
2323 * read.c (conditional_line): Expand the text after ifn?def before
2324 checking to see if it's a single word. Fixes bug #7257.
2326 2004-01-09 Paul D. Smith <psmith@gnu.org>
2328 * file.c (print_file): Recurse to print all targets in
2329 double-colon rules. Fixes bug #4518, reported (with patch) by
2330 Andrew Chatham <chatham@google.com>.
2332 2004-01-07 Paul D. Smith <psmith@gnu.org>
2334 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2335 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2336 AC_FUNC_SETVBUF_REVERSED.
2338 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2339 (MAKE Variable): Fix Savannah bug #4898.
2341 * job.c (construct_command_argv_internal): Add "!" to the list of
2342 shell escape chars. POSIX sh allows it to appear before a
2343 command, to negate the exit code. Fixes bug #6404.
2345 * implicit.c (pattern_search): When matching an implicit rule,
2346 remember which dependencies have the ignore_mtime flag set.
2347 Original fix provided in Savannah patch #2349, by Benoit
2348 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2350 2003-11-22 Paul D. Smith <psmith@gnu.org>
2352 * README.W32.template (Outputs): Clarification on -j with
2353 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2356 2003-11-02 Paul D. Smith <psmith@gnu.org>
2358 * function.c (func_if): Strip all the trailing whitespace from the
2359 condition, then don't expand it. Fixed bug # 5798.
2361 * expand.c (recursively_expand_for_file): If we're expanding a
2362 variable with no file context, then use the variable's context.
2365 2003-10-21 Paul D. Smith <psmith@gnu.org>
2367 * main.c (log_working_directory): Add newlines to printf()s.
2369 * README.cvs: Add a note to ignore warnings during autoreconf.
2371 * maintMakefile (po_repo): Set a new URL for PO file updates.
2372 (get-config/config.guess get-config/config.sub): Get these files
2373 from the Savannah config project instead of ftp.gnu.org.
2375 2003-10-05 Paul Eggert <eggert@twinsun.com>
2377 * main.c (main): Avoid potential subscript error if environ has
2380 2003-08-22 Paul D. Smith <psmith@gnu.org>
2382 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2383 systems which don't yet implement the C89 standard :-/.
2385 2003-07-18 Paul D. Smith <psmith@gnu.org>
2387 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2388 [WINDOWS32]: Initialize hash.
2390 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2392 * dir.c (read_dirstream): Provide a workaround for broken versions of
2393 the MinGW dirent structure.
2395 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2397 * w32/include/dirent.h: Add __MINGW32__ filter.
2399 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2401 * make.h: Add global declaration of *make_host.
2402 * main.c (print_usage): Remove local declaration of *make_host.
2403 (print_version): Display "This program built for ..." after Copyright
2406 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2408 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2409 execution of "makeinfo --html make.texi".
2411 2003-04-30 Paul D. Smith <psmith@gnu.org>
2413 * build.template: Make some changes to maybe allow this script to
2414 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2416 * README.OS2.template: New file for OS/2 support. Original
2417 contributed by Andreas Buening.
2418 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2421 2003-04-19 Paul D. Smith <psmith@gnu.org>
2423 Fix bug #1405: allow a target to match multiple pattern-specific
2426 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2427 variable.c, where they've always belonged.
2428 * rule.h: Move the prototypes and struct pattern_var as well.
2429 * variable.c (initialize_file_variables): Invoke
2430 lookup_pattern_var() in a loop, until no more matches are found.
2431 If a match is found, create a new variable set for the target's
2432 pattern variables. Then merge the contents of each matching
2433 pattern variable set into the target's pattern variable set.
2434 (lookup_pattern_var): Change this function to be usable
2435 in a loop. It takes a starting position: if NULL, start at the
2436 beginning; if non-NULL, start with the pattern variable after that
2437 position, and return the next matching pattern.
2438 (create_pattern_var): Create a unique instance of
2439 pattern-specific variables for every definition in the makefile.
2440 Don't combine the same pattern together. This allows us to
2441 process the variable handling properly even when the same pattern
2442 is used multiple times.
2443 (parse_variable_definition): New function: break out the parsing
2444 of a variable definition line from try_variable_definition.
2445 (try_variable_definition): Call parse_variable_definition to
2447 (print_variable_data_base): Print out pattern-specific variables.
2448 * variable.h (struct variable): Remember when a variable is
2449 conditional. Also remember its flavor.
2450 (struct pattern_var): Instead of keeping a variable set, we just
2451 keep a single variable for each pattern.
2452 * read.c (record_target_var): Each pattern variable contains only a
2453 single variable, not a set, so create it properly.
2454 * doc/make.texi (Pattern-specific): Document the new behavior.
2456 2003-04-17 Paul D. Smith <psmith@gnu.org>
2458 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2459 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2460 file/directory naming rules for VMS so I can't tell whether this
2463 2003-04-09 Paul D. Smith <psmith@gnu.org>
2465 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2466 DOS-style pathnames: backslash separators and drive specifiers.
2468 2003-03-28 Paul D. Smith <psmith@gnu.org>
2470 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2471 the intermediate flag on all targets. Fixes bug #2515.
2473 2003-03-24 Paul D. Smith <psmith@gnu.org>
2475 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2476 Upgrade to autoconf 2.57 and automake 1.7.3.
2478 * job.c: More OS/2 changes from Andreas Buening.
2480 * file.c (print_file): Fix variable initialization.
2483 * remake.c (notice_finished_file):
2485 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2486 some calls (like readdir()) return NULL in valid situations
2487 without resetting errno. Fixes bug #2846.
2489 2003-02-25 Paul D. Smith <psmith@gnu.org>
2491 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2493 * job.c (_is_unixy_shell) [OS/2]: New function.
2494 Set default shell to /bin/sh.
2495 (reap_children): Close the job_rfd pipe here since we don't use a
2497 (set_child_handler_action_flags): define this to empty on OS/2.
2498 (start_job_command): Close the jobserver pipe and use
2499 child_execute_job() instead of fork/exec.
2500 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2501 rather than exec'ing, then reconfigure stdin/stdout.
2502 (exec_command): Rewrite to use spawn instead of exec. Return the
2505 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2506 in DOS. Handle the TEMP environment variable as in DOS. Don't
2507 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2508 use -j in DOS mode. Use child_execute_job() instead of
2511 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2514 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2515 prototypes that return values.
2517 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2519 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2520 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2522 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2525 2003-02-24 Paul D. Smith <psmith@gnu.org>
2527 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2528 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2529 (child_execute_job) [VMS]: Handle error status properly.
2530 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2532 * function.c (func_shell): Use EINTRLOOP() while reading from the
2533 subshell pipe (Fixes bug #2502).
2534 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2536 * main.c (main): Ditto.
2538 2003-01-30 Paul D. Smith <psmith@gnu.org>
2540 * read.c (eval): eval() was not fully reentrant, because the
2541 collapsed buffer was static. Change it to be an automatic
2542 variable so that eval() can be invoked recursively.
2544 (eval): Apply patch # 1022: fix memory reference error on long
2545 target-specific variable lines.
2546 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2548 * function.c (check_numeric): Combine the is_numeric() function
2549 into this function, since it's only called from one place.
2550 Constify this function. Have it print the incorrect string in the
2551 error message. Fixes bug #2407.
2552 (strip_whitespace): Constify.
2553 (func_if): Constify.
2554 * expand.c (expand_argument): Constify.
2556 2003-01-29 Paul D. Smith <psmith@gnu.org>
2558 Fix bug # 2169, also reported by other people on various systems.
2560 * make.h: Some systems, such as Solaris and PTX, do not fully
2561 implement POSIX-compliant SA_RESTART functionality; important
2562 system calls like stat() and readdir() can still fail with EINTR
2563 even if SA_RESTART has been set on the signal handler. So,
2564 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2565 EINTR for system calls which return -1 or 0 (NULL), respectively,
2567 Also, remove the old atomic_stat()/atomic_readdir() and
2568 HAVE_BROKEN_RESTART handling.
2570 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2572 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2573 * remake.c (touch_file): Ditto.
2575 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2576 * read.c (construct_include_path): Ditto.
2577 * remake.c (name_mtime): Ditto.
2578 * vpath.c (selective_vpath_search): Ditto.
2579 * dir.c (find_directory): Ditto.
2580 (local_stat): Ditto.
2581 (find_directory): Use ENULLLOOP() to wrap opendir().
2582 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2584 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2585 atomic_readdir() handling.
2587 2003-01-22 Paul D. Smith <psmith@gnu.org>
2589 * function.c (func_call): Fix Bug #1744. If we're inside a
2590 recursive invocation of $(call ...), mask any of the outer
2591 invocation's arguments that aren't used by this one, so that this
2592 invocation doesn't "inherit" them accidentally.
2594 2002-12-05 Paul D. Smith <psmith@gnu.org>
2596 * function.c (subst_expand): Valery Khamenia reported a
2597 pathological performance hit when doing substitutions on very
2598 large values with lots of words: turns out we were invoking
2599 strlen() a ridiculous number of times. Instead of having each
2600 call to sindex() call strlen() again, keep track of how much of
2601 the text we've seen and pass the length to sindex().
2603 2002-11-19 Paul D. Smith <psmith@gnu.org>
2605 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2608 2002-11-16 Paul D. Smith <psmith@gnu.org>
2610 * NMakefile.template (OBJS): Add hash.c object file.
2611 * SMakefile.template (srcs): Ditto.
2612 * Makefile.ami (objs): Ditto.
2613 * build_w32.bat: Ditto.
2615 * Makefile.DOS.template: Remove extra dependencies.
2617 2002-10-25 Paul D. Smith <psmith@gnu.org>
2619 * expand.c (install_variable_buffer): New function. Install a new
2620 variable_buffer context and return the previous one.
2621 (restore_variable_buffer): New function. Free the current
2622 variable_buffer context and put a previously saved one back.
2623 * variable.h: Prototypes for {install,restore}_variable_buffer.
2624 * function.c (func_eval): Push a new variable_buffer context
2625 before we eval, then restore the old one when we're done.
2628 * read.c (install_conditionals): New function. Install a new
2629 conditional context and return the previous one.
2630 (restore_conditionals): New function. Free the current
2631 conditional context and put a previously saved one back.
2632 (eval): Use the {install,restore}_conditionals for "include"
2634 (eval_buffer): Use {install,restore}_conditionals to preserve the
2635 present conditional state before we evaluate the buffer.
2638 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2640 (Recursion): Add a variable index entry for CURDIR.
2642 * README.cvs: Update to appropriate versions.
2643 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2644 don't need to copy loadavg.c: automake is smart enough to create
2645 it for me. Still have a bug in automake related to ansi2knr tho.
2647 2002-10-14 Paul D. Smith <psmith@gnu.org>
2649 * remake.c (notice_finished_file): Only touch targets if they have
2650 at least one command (as per POSIX). Resolve Bug #1418.
2652 * *.c: Convert to using ANSI C-style function definitions.
2653 * Makefile.am: Enable the ansi2knr feature of automake.
2654 * configure.in: ditto.
2656 2002-10-13 Paul D. Smith <psmith@gnu.org>
2658 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2659 for automatic variable values like $^, etc. In the case of very
2660 large lists of prerequisites this causes problems. Instead reuse
2661 a static buffer (resizeable) for each variable.
2663 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2664 target-specific variable definitions. Check for it and set an
2666 (record_target_var): Set the export field to v_export if the
2667 "exported" flag is set.
2668 * doc/make.texi (Target-specific): Document the ability to use
2671 * doc/make.texi: Change the name of the section on automatic
2672 variables from "Automatic" to "Automatic Variables". Added text
2673 clarifying the scope of automatic variables.
2675 2002-10-04 Paul D. Smith <psmith@gnu.org>
2677 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2679 (record_files): Ditto.
2681 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2682 the search for the '=' to only within the enclosing parens.
2684 2002-10-03 Paul D. Smith <psmith@gnu.org>
2686 Version 3.80 released.
2688 * dir.c: Change hash functions to use K&R function definition style.
2689 * function.c: Ditto.
2691 * variable.c: Ditto.
2693 Update to automake 1.7.
2695 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2696 (pdf): Remove this target as automake now provides one.
2698 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2700 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2702 * makefile.com: Updates for GNU make 3.80.
2703 * makefile.vms: Ditto.
2705 2002-09-23 Paul D. Smith <psmith@gnu.org>
2707 * read.c (enum make_word_type): Remove w_comment.
2708 (get_next_mword): Don't treat comment characters as special; where
2709 this function is used we will never see a comment (it's stripped
2710 before we get here) and treating comments specially means that
2711 targets like "foo\#bar" aren't handled properly.
2713 2002-09-18 Paul D. Smith <psmith@gnu.org>
2715 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2717 * read.c (eval): Expansion of arguments to export/unexport was
2718 ignoring all arguments after the first one. Change the algorithm
2719 to expand the whole line once, then parse the results.
2721 2002-09-17 Paul D. Smith <psmith@gnu.org>
2723 Fix Bug #940 (plus another bug I found while looking at this):
2725 * read.c (record_target_var): enter_file() will add a new entry if
2726 it's a double-colon target: we don't want to do that in this
2727 situation. Invoke lookup_file() and only enter_file() if it does
2728 not already exist. If the file we get back is a double-colon then
2729 add this variable to the "root" double-colon target.
2731 * variable.c (initialize_file_variables): If this file is a
2732 double-colon target but is not the "root" target, then initialize
2733 the root and make the root's variable list the parent of our
2736 2002-09-13 Paul D. Smith <psmith@gnu.org>
2738 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2740 * hash.c (round_up_2): Get rid of a warning.
2742 2002-09-12 Paul D. Smith <psmith@gnu.org>
2744 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2745 so it doesn't complain about getloadavg.c.
2747 * commands.c (set_file_variables): Make sure we always alloca() at
2748 least 1 character for the value of $? (for '\0').
2750 2002-09-11 Paul D. Smith <psmith@gnu.org>
2752 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2753 macro to use RESULT instead of the incorrect _RESULT_.
2755 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2756 and atomic_readdir(). We need to #include dirent.h to get this to
2758 * misc.c (atomic_readdir): Fix typos.
2760 2002-09-10 Paul D. Smith <psmith@gnu.org>
2762 * read.c (eval): Expand variable lists given to export and
2763 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2764 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2766 * doc/make.texi (Variables/Recursion): Document this.
2767 (Conditional Syntax): And here.
2769 2002-09-09 Paul D. Smith <psmith@gnu.org>
2771 * configure.in: Check for memmove().
2773 2002-09-07 Paul D. Smith <psmith@gnu.org>
2775 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2776 Michael Sterrett <msterret@coat.com> reports that while it has
2777 SA_RESTART, it does not work properly.
2779 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2780 that invokes stat() and loops to do it again if it returns EINTR.
2781 (atomic_readdir): Ditto, with readdir().
2783 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2784 and readdir() to atomic_stat() and atomic_readdir().
2786 2002-09-04 Paul D. Smith <psmith@gnu.org>
2788 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2789 reports that GNU make sometimes doesn't recognize that targets can
2790 be made, when directories can be created as prerequisites. He
2791 reports that changing the order of predicates in the DEP->changed
2792 flag test so that lookup_file() is always performed, solves this
2795 2002-08-08 Paul D. Smith <psmith@gnu.org>
2797 * configure.in: Require a newer version of gettext.
2799 * misc.c (perror_with_name): Translate the format string (for
2800 right-to-left language support).
2801 (pfatal_with_name): Ditto.
2803 * main.c: Create a static array of strings to store the usage
2804 text. This is done to facilitate translations.
2805 (struct command_switch): Remove argdesc and description fields.
2806 (switches): Remove values for obsolete fields.
2807 (print_usage): Print each element of the usage array.
2809 * hash.c: Change function definitions to be K&R style.
2811 2002-08-02 Paul D. Smith <psmith@gnu.org>
2813 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2814 this one because it's too hard to get right. We'll look at it for
2816 * main.c (main): Don't create the .TARGETS variable.
2817 * variable.c (handle_special_var): Don't handle .TARGETS.
2819 2002-08-01 Paul D. Smith <psmith@gnu.org>
2821 * main.c (switches): Add a new option, -B (--always-make). If
2822 specified, make will rebuild all targets that it encounters even
2823 if they don't appear to be out of date.
2824 (always_make_flag): New flag.
2825 * make.h: Extern always_make_flag.
2826 * remake.c (update_file_1): Check always_make_flag; if it's set we
2827 will always rebuild any target we can, even if none of its
2828 prerequisites are newer.
2831 * doc/make.texi (Shell Function): Make it clear that make
2832 variables marked as "export" are not passed to instances of the
2835 Add new introspection variable .VARIABLES and .TARGETS.
2837 * variable.c (handle_special_var): New function. If the variable
2838 reference passed in is "special" (.VARIABLES or .TARGETS),
2839 calculate the new value if necessary. .VARIABLES is handled here:
2840 walk through the hash of defined variables and construct a value
2841 which is a list of the names. .TARGETS is handled by
2842 build_target_list().
2843 (lookup_variable): Invoke handle_special_var().
2844 * file.c (build_target_list): Walk through the hask of known files
2845 and construct a list of the names of all the ones marked as
2847 * main.c (main): Initialize them to empty (and as simple variables).
2848 * doc/make.texi (Special Variables): Document them.
2849 * NEWS: Mention them.
2851 * variable.h (struct variable): Add a new flag "exportable" which
2852 is true if the variable name is valid for export.
2853 * variable.c (define_variable_in_set): Set "exportable" when a new
2854 variable is defined.
2855 (target_environment): Use the "exportable" flag instead of
2856 re-checking the name here... an efficiency improvement.
2858 2002-07-31 Paul D. Smith <psmith@gnu.org>
2860 * config.h-vms.template: Updates to build on VMS. Thanks to
2861 Brian_Benning@aksteel.com for helping verify the build.
2862 * makefile.com: Build the new hash.c file.
2863 * hash.h: Use strcpmi(), not stricmp(), in the
2864 HAVE_CASE_INSENSITIVE_FS case.
2866 2002-07-30 Paul D. Smith <psmith@gnu.org>
2868 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2869 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2870 Reported by <Brian_Benning@aksteel.com>.
2872 2002-07-10 Paul D. Smith <psmith@gnu.org>
2874 * variable.c (pop_variable_scope): Remove variable made unused by
2875 new hash infrastructure.
2876 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2877 comparisons as well as name comparisons.
2878 * variable.h: Add a prototype for new hash_init_function_table().
2879 * file.c (lookup_file): Remove variables made unused by new hash
2881 * dir.c (directory_contents_hash_2): Missing return of hash value.
2882 (dir_contents_file_exists_p): Remove variables made unused by new
2883 hash infrastructure.
2886 Installed Greg McGary's integration of the hash functions from the
2887 GNU id-utils package:
2889 2002-07-10 Greg McGary <greg@mcgary.org>
2891 * scripts/functions/filter-out: Add literals to to the
2892 pattern space in order to add complexity, and trigger
2893 use of an internal hash table. Fix documentation strings.
2894 * scripts/targets/INTERMEDIATE: Reverse order of files
2895 passed to expected `rm' command.
2897 2002-07-10 Greg McGary <greg@mcgary.org>

2989 2002-07-10 Paul D. Smith <psmith@gnu.org>
2991 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2992 prerequisite list. A real SysV make will expand the entire
2993 prerequisites list _twice_: we don't do that as it's a big
2994 backward-compatibility problem. We only replace those specific
2997 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2998 references left in the list of prerequisites. Check for .POSIX as
2999 we record targets, so we can disable non-POSIX behavior while
3000 reading makefiles as well as running them.
3001 (eval): Check the prerequisite list to see if we have anything
3002 that looks like a SysV prerequisite variable reference.
3004 2002-07-09 Paul D. Smith <psmith@gnu.org>
3006 * doc/make.texi (Prerequisite Types): Add a new section describing
3007 order-only prerequisites.
3009 * read.c (uniquize_deps): If we have the same file as both a
3010 normal and order-only prereq, get rid of the order-only prereq,
3011 since the normal one supersedes it.
3013 2002-07-08 Paul D. Smith <psmith@gnu.org>
3015 * AUTHORS: Added Greg McGary to the AUTHORS file.
3016 * NEWS: Blurbed order-only prerequisites.
3017 * file.c (print_file): Show order-only deps properly when printing
3020 * maintMakefile: Add "update" targets for wget'ing the latest
3021 versions of various external files. Taken from Makefile.maint in
3024 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3025 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3027 2002-07-07 Paul D. Smith <psmith@gnu.org>
3029 * po/*.po: Remove. We'll use wget to retrieve them at release
3032 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3033 rather than a shell you get an exception. Make sure we look up
3034 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3036 * remake.c (notice_finished_file): Fix handling of -t flag.
3037 Patch provided by Henning Makholm <henning@makholm.net>.
3039 * implicit.c (pattern_search): Some systems apparently run short
3040 of stack space, and using alloca() in this function caused an
3041 overrun. I modified it to use xmalloc() on the two variables
3042 which seemed like they might get large. Fixes Bug #476.
3044 * main.c (print_version): Update copyright notice to conform with
3046 (print_usage): Update help output.
3048 * function.c (func_eval): Create a new make function, $(eval
3049 ...). Expand the arguments, put them into a buffer, then invoke
3050 eval_buffer() on the resulting string.
3051 (func_quote): Create a new function, $(quote VARNAME). Inserts
3052 the value of the variable VARNAME without expanding it any
3055 * read.c (struct ebuffer): Change the linebuffer structure to an
3056 "eval buffer", which can be either a file or a buffer.
3057 (eval_makefile): Move the code in the old read_makefile() which
3058 located a makefile into here: create a struct ebuffer with that
3059 information. Have it invoke the new function eval() with that
3061 (eval_buffer): Create a new function that creates a struct ebuffer
3062 that holds a string buffer instead of a file. Have it invoke
3063 eval() with that ebuffer.
3064 (eval): New function that contains the guts of the old
3065 read_makefile() function: this function parses makefiles. Obtains
3066 data to parse from the provided ebuffer. Some modifications to
3067 make the flow of the function cleaner and clearer. Still could
3068 use some work here...
3069 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3070 contents of the define/endef variable from the ebuffer.
3071 (readstring): Read the next line from a string-style ebuffer.
3072 (readline): Read the next line from an ebuffer. If it's a string
3073 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3076 * dep.h (eval_buffer): Prototype eval_buffer();
3078 * variable.c (do_variable_definition): Make sure that all
3079 non-target-specific variables are registered in the global set.
3080 If we're invoked from an $(eval ...) we might be inside a $(call
3081 ...) or other function which has pushed a variable scope; we still
3082 want to define our variables from evaluated makefile code in the
3085 2002-07-03 Greg McGary <greg@mcgary.org>
3087 * dep.h (struct dep) [ignore_mtime]: New member.
3088 [changed]: convert to a bitfield.
3089 * implicit.c (pattern_search): Zero ignore_mtime.
3090 * main.c (main, handle_non_switch_argument): Likewise.
3091 * rule.c (convert_suffix_rule): Likewise.
3092 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3093 (read_makefile): Parse '|' in prerequisite list.
3094 (uniquize_deps): Consider ignore_mtime when comparing deps.
3095 * remake.c (update_file_1, check_dep): Don't force remake for
3096 dependencies that have d->ignore_mtime.
3097 * commands.c (FILE_LIST_SEPARATOR): New constant.
3098 (set_file_variables): Don't include a
3099 prerequisite in $+, $^ or $? if d->ignore_mtime.
3102 2002-06-18 Paul D. Smith <psmith@gnu.org>
3104 * make.texinfo: Updates for next revision. New date/rev/etc.
3105 Recreate all Info menus. Change license on the manual to the GNU
3106 Free Documentation License. A number of typos.
3107 (Variables Simplify): Don't use "-" before it's defined.
3108 (Automatic Prerequisites): Rewrite the target example to work
3109 properly if the compile fails. Remove incorrect comments about
3110 how "set -e" behaves.
3111 (Text Functions): Move the "word", "wordlist", "words", and
3112 "firstword" functions here, from "File Name Functions".
3113 * make-stds.texi: Update from latest GNU version.
3114 * fdl.texi: (created) Import the latest GNU version.
3116 2002-06-06 Paul D. Smith <psmith@gnu.org>
3118 * variable.c (do_variable_definition): New function: extract the
3119 part of try_variable_definition() that actually sets the value
3120 into a separate function.
3121 (try_variable_definition): Call do_variable_definition() after
3122 parsing the variable definition string.
3123 (define_variable_in_set): Make the name argument const.
3125 * variable.h (enum variable_flavor): Make public.
3126 (do_variable_definition): Create prototype.
3128 * read.c (read_all_makefiles): Create a new built-in variable,
3130 (read_makefile): Add each makefile read in to this variable value.
3132 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3134 * Makefile.DOS.template: Tweak according to changes in the
3135 distribution. Add back the dependencies of *.o files.
3137 * configh.dos.template: Synchronize with config.h.in.
3139 2002-05-09 Paul D. Smith <psmith@gnu.org>
3141 * file.c (file_timestamp_now): Use K&R function declaration.
3143 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3144 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3145 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3146 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3147 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3148 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3149 nlist.n_name is a pointer rather than an array.
3151 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3152 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3153 * configure.in: Use it instead of the old version.
3155 * main.c (main): Prefer setvbuf() to setlinebuf().
3157 2002-05-08 Paul D. Smith <psmith@gnu.org>
3159 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3160 (loadavg_LDADD): Ditto.
3162 2002-04-29 Paul D. Smith <psmith@gnu.org>
3164 * expand.c (recursively_expand_for_file): Rename
3165 recursively_expand() to recursively_expand_for_file() and provide
3166 an extra argument, struct file. If the argument is provided, set
3167 the variable scope to that of the file before expanding.
3168 * variable.h (recursively_expand): Make this a macro that invokes
3169 recursively_expand_for_file() with a NULL file pointer.
3170 * variable.c (target_environment): Call the renamed function and
3171 provide the current file context.
3172 Fixes Debian bug #144306.
3174 2002-04-28 Paul D. Smith <psmith@gnu.org>
3176 Allow $(call ...) user-defined variables to be self-referencing
3177 without throwing an error. Allows implementation of transitive
3178 closures, among other possibly useful things.
3179 Requested by: Philip Guenther <guenther@sendmail.com>
3181 * variable.h (struct variable): Add a new field: exp_count, and
3182 new macros to hold its size and maximum value.
3183 (warn_undefined): Make this a macro.
3184 * variable.c (define_variable_in_set): Initialize it.
3185 * expand.c (recursively_expand): If we detect recursive expansion
3186 of a variable, check the exp_count field. If it's greater than 0
3187 allow the recursion and decrement the count.
3188 (warn_undefined): Remove this (now a macro in variable.h).
3189 * function.c (func_call): Before we expand the user-defined
3190 function, modify its exp_count field to contain the maximum
3191 number of recursive calls we'll allow. After the call, reset it
3194 2002-04-21 Paul D. Smith <psmith@gnu.org>
3196 Modified to use latest autoconf (2.53), automake (1.6.1), and
3197 gettext (0.11.1). We're using gettext's new "external" support,
3198 to avoid including libintl source with GNU make.
3200 * README.cvs: New file. Explain how to build GNU make from CVS.
3202 * configure.in: Modify checking for the system glob library.
3203 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3204 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3205 etc. will manage it correctly). Set an automake conditional
3206 USE_LOCAL_GLOB to decide whether to compile the glob library.
3208 * getloadavg.c (main): Include make.h in the "TEST" program to
3211 * Makefile.am: Remove special rules for loadavg. Replace them
3212 with Automake capabilities for building extra programs.
3214 * signame.c: This file does nothing if the system provide
3215 strsignal(). If not, it implements strsignal(). If the system
3216 doesn't define sys_siglist, then we make our own; otherwise we use
3218 * signame.h: Removed.
3220 * main.c (main): No need to invoke signame_init(). Update copyright.
3222 * ABOUT-NLS: Removed.
3223 * gettext.c: Removed.
3224 * gettext.h: Get a simplified copy from the gettext package.
3226 * i18n/*.po: Moved to po/.
3229 * config/*: Created. Contains package configuration helper files.
3230 * config.guess, config.sub: Moved to config directory.
3232 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3233 Rework to use new-style autoconf features. Use the "external"
3234 mode for gettext. Make the build.sh config file conditional on
3235 whether build.sh.in exists, to avoid autoconf errors.
3236 * acinclude.m4: Removed almost all macros as being obsolete.
3237 Rewrote remaining macros to use AC_DEFINE.
3238 * acconfig.h: Removed.
3240 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3241 conditional to handle customs support. Remove special handling
3244 2002-04-20 Paul D. Smith <psmith@gnu.org>
3246 * function.c (func_call): Don't mark the argument variables $1,
3247 etc. as recursive. They've already been fully expanded so
3248 there's no need to do it again, and doing so strips escaped $'s.
3249 Reported by Sebastian Glita <glseba@yahoo.com>.
3251 * remake.c (notice_finished_file): Walk through double-colon
3252 entries via the prev field, not the next field!
3253 Reported by Greg McGary <greg@mcgary.org>.
3255 * main.c (main): If the user specifies -q and asks for a specific
3256 target which is a makefile, we got an assert. In that case it
3257 turns out we should continue normally instead.
3259 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3261 * i18n/he.po: Installed a new translation.
3263 2002-01-07 Paul D. Smith <psmith@gnu.org>
3265 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3267 2001-12-04 Paul D. Smith <psmith@gnu.org>
3269 * i18n/ja.po: Installed an updated translation.
3271 2001-09-06 Paul Eggert <eggert@twinsun.com>
3273 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3274 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3276 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3278 (main): Get rid of any avoidable limit on stack size.
3280 2001-09-04 Paul D. Smith <psmith@gnu.org>
3282 * i18n/da.po: Installed an updated translation.
3284 2001-08-03 Paul D. Smith <psmith@gnu.org>
3286 * i18n/fr.po: Installed an updated translation.
3287 Resolves Debian bug #106720.
3289 2001-06-13 Paul D. Smith <psmith@gnu.org>
3291 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3294 2001-06-11 Paul D. Smith <psmith@gnu.org>
3296 * i18n/ko.po: Installed a new translation.
3298 2001-05-06 Paul D. Smith <psmith@gnu.org>
3300 Modify the EINTR handling.
3302 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3303 the way in which we manage the file descriptor/signal handler race
3304 trap to be more efficient.
3306 2001-05-06 Paul Eggert <eggert@twinsun.com>
3308 Restart almost all system calls that are interrupted, instead
3309 of worrying about EINTR. The lone exception is the read() for
3312 * configure.in (HAVE_SA_RESTART): New macro.
3313 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3314 * main.c (main): Use SA_RESTART instead of the old,
3315 nonstandard SA_INTERRUPT.
3317 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3318 * main.c (bsd_signal): New function or macro,
3319 if the implementation doesn't supply it.
3320 (The bsd_signal function will be in POSIX 1003.1-200x.)
3321 (HANDLESIG): Remove.
3322 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3324 * make.h (EINTR_SET): Remove.
3325 (SA_RESTART): New macro.
3327 * arscan.c (ar_member_touch): Don't worry about EINTR.
3328 * function.c (func_shell): Likewise.
3329 * job.c (reap_children, free_child, new_job): Likewise.
3330 * main.c (main): Likewise.
3331 * remake.c (touch_file, name_mtime): Likewise.
3333 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3334 if fstat failed with errno!=EINTR, the error was ignored.
3336 * job.c (set_child_handler_action_flags): New function.
3337 (new_job): Use it to temporarily clear the SIGCHLD action flags
3338 while reading the token.
3340 2001-05-02 Paul D. Smith <psmith@gnu.org>
3342 * job.c (start_job_command): Don't add define/endef per-line flags
3343 to the top-level flags setting.
3345 2001-04-03 Paul D. Smith <psmith@gnu.org>
3347 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3348 bit on error, so check for odd return values, not non-0 return
3350 (VMS_get_member_info): Calculate the timezone differences correctly.
3351 Reported by John Fowler <jfowler@nyx.net>.
3354 2001-03-14 Paul D. Smith <psmith@gnu.org>
3356 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3357 value before invoking define_variable().
3358 Reported by John Fowler <jfowler@nyx.net>.
3360 2001-02-07 Paul D. Smith <psmith@gnu.org>
3362 * read.c (record_target_var): If we reset the variable due to a
3363 command-line variable setting overriding it, turn off the "append"
3366 2001-01-17 Paul D. Smith <psmith@gnu.org>
3368 * variable.c (lookup_variable) [VMS]: When getting values from the
3369 environment, allocate enough space for the _value_ plus escapes,
3370 not enough space for the name plus escapes :-/.
3371 Reported by John Fowler <jfowler@nyx.net>.
3373 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3374 warnings that make generates, so it doesn't look like an error.
3375 Reported by Karl Berry <karl@gnu.org>.
3378 Fix for PR/2020: Rework appended target-specific variables. I'm
3379 fairly confident this algorithm is finally correct.
3381 * expand.c (allocated_variable_append): Rewrite. Instead of
3382 expanding each appended variable then adding all the expanded
3383 strings together, we append all the unexpanded values going up
3384 through the variable set contexts, then expand the final result.
3385 This behaves just like non-target-specific appended variable
3386 values, while the old way didn't in various corner cases.
3387 (variable_append): New function: recursively append the unexpanded
3388 value of a variable, walking from the outermost variable scope to
3390 * variable.c (lookup_variable): Remove the code that looked up the
3391 variable set list if the found variable was "append". We don't
3393 (lookup_variable_in_set): Make this non-static so we can use it
3395 (try_variable_definition): Use lookup_variable_in_set() rather
3396 than faking out current_variable_set_list by hand (cleanup).
3397 * variable.h: Add a prototype for the now non-static
3398 lookup_variable_in_set().
3400 2000-11-17 Paul D. Smith <psmith@gnu.org>
3402 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3403 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3404 before throwing a fit.
3406 2000-11-17 Paul D. Smith <psmith@gnu.org>
3408 * read.c (readline): CRLF calculations had a hole, if you hit the
3409 buffer grow scenario just right. Reworked the algorithm to avoid
3410 the need for len or lastlen at all. Problem description with
3411 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3413 2000-10-24 Paul D. Smith <psmith@gnu.org>
3415 * gettext.c (SWAP): Declare this with the prototype, otherwise
3416 some systems don't work (non-32-bit? Reported for Cray T3E).
3417 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3419 2000-10-05 Paul D. Smith <psmith@gnu.org>
3421 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3422 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3424 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3426 2000-09-22 Paul D. Smith <psmith@gnu.org>
3428 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3429 parts of the real gettext.h here, and we expect to really include
3430 the real gettext.h later. If we keep this #define, it's ignored.
3432 2000-09-21 Paul D. Smith <psmith@gnu.org>
3434 * main.c (log_working_directory): Rework the text to use complete
3435 sentences, to make life simpler for the translators.
3437 2000-08-29 Paul D. Smith <psmith@gnu.org>
3439 * file.c (remove_intermediates): Print a debug message before we
3440 remove intermediate files, so the user (if she uses -d) knows
3443 2000-08-21 Paul D. Smith <psmith@gnu.org>
3445 * variable.c (try_variable_definition): Change how we handle
3446 target-specific append variable defns: instead of just setting the
3447 value, expand it as an append _but_ only within the current
3448 target's context. Otherwise we lose all but the last value if the
3449 variable is appended more than once within the current target
3450 context. Fixes PR/1831.
3452 2000-08-16 Paul D. Smith <psmith@gnu.org>
3454 * function.c (func_shell): Nul-terminate the buffer before
3455 printing an exec error message (just in case it's not!).
3456 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3458 2000-07-25 Paul D. Smith <psmith@gnu.org>
3460 * job.c (construct_command_argv_internal): Add "~" to the list of
3461 sh_chars[] which disallow optimizing out the shell call.
3463 2000-07-23 Paul Eggert <eggert@twinsun.com>
3465 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3466 supersedes --disable-nsec-timestamps.
3467 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3468 * README: Remove --disable-nsec-timestamps.
3470 * filedef.h (struct file.low_resolution_time): New member.
3471 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3472 * remake.c (update_file_1):
3473 Avoid spurious rebuilds due to low resolution time stamps,
3474 generalizing the earlier code that applied only to archive members.
3475 (f_mtime): Archive members always have low resolution time stamps.
3477 * configure.in: Remove --disable-nsec-timestamps, as this has
3478 been superseded by .LOW_RESOLUTION_TIME.
3480 2000-07-23 Paul Eggert <eggert@twinsun.com>
3482 * configure.in (enable_nsec_timestamps): Renamed from
3483 make_cv_nsec_timestamps, since enable/disable options
3484 shouldn't be cached.
3486 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3487 and Paul Eggert <eggert@twinsun.com>
3489 * file.c (file_timestamp_now):
3490 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3491 so that clock_gettime is not linked unless needed.
3493 * filedef.h (FILE_TIMESTAMP_HI_RES):
3494 Remove definition; "configure" now does this.
3496 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3497 to before high resolution file timestamp check,
3498 since that check now uses uintmax_t.
3499 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3500 high resolution file timestamps.
3501 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3502 so that we don't link in clock_gettime unnecessarily.
3504 2000-07-17 Paul D. Smith <psmith@gnu.org>
3506 * i18n/ja.po: New version of the translation file.
3508 2000-07-07 Paul D. Smith <psmith@gnu.org>
3510 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3511 the offset calculation.
3512 (name_mtime): Replace EINTR test with EINTR_SET macro.
3514 2000-07-07 Paul Eggert <eggert@twinsun.com>
3518 * remake.c (update_file_1):
3519 Avoid spurious rebuilds of archive members due to their
3520 timestamp resolution being only one second.
3521 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3522 the clock's resolution being lower than file timestamps'.
3523 When warning about future timestamps, report only the discrepancy,
3524 not the absolute value of the timestamp and the current time.
3526 * file.c (file_timestamp_now): New arg RESOLUTION.
3527 * filedef.h (file_timestamp_now): Likewise.
3528 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3530 2000-07-05 Paul D. Smith <psmith@gnu.org>
3532 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3533 to listp. Fixes PR/1793.
3535 2000-06-26 Paul Eggert <eggert@twinsun.com>
3537 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3539 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3541 * remake.c (f_mtime): Remove unused var memtime.
3543 2000-06-25 Martin Buchholz <martin@xemacs.org>
3545 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3546 Ran spell-check on make.texinfo.
3548 2000-06-23 Paul D. Smith <psmith@gnu.org>
3550 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3551 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3552 * make.h: Define these macros.
3554 * Version 3.79.1 released.
3556 * configure.in: Add a new option, --disable-nsec-timestamps, to
3557 avoid using sub-second timestamps on systems that support it. It
3558 can lead to problems, e.g. if your makefile relies on "cp -p".
3559 * README.template: Document the issue with "cp -p".
3561 * config.guess, config.sub: Updated.
