1 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3 * configh.dos.template: Remove unconditional definition of
4 SYS_SIGLIST_DECLARED.
5 Include <sys/version.h> because ports of GCC 4.3.0 and later no
6 longer include it, so macros like __DJGPP_MINOR__ are no longer
7 defined automatically.
9 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
10 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
11 instead of using the hardcoded ones.
12 (SUBDIRS): doc subdir added.
13 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
14 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
15 create html formated docs. texi2html may not be ported to DOS.
16 (make.info, make.dvi, make.ps, make.html): Make targets depend on
17 'make.texi'.
18 (.texi.info, .texi, .texi.dvi): Now recursively invocate. Change
19 -I switch to look in ./ instead of ./doc.
20 (html): Target depend on html-recursive instead of make_1.html.
21 (make_1.html): Removed.
22 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
23 (all-recursive): Allow for more than one subdir in the build
24 process.
25 (mostlyclean-recursive, clean-recursive, distclean-recursive)
26 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
27 (tags-recursive): Allow for more than one subdir in the build
28 process.
29 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
30 targets. Enter into doc/ to produce the targets.
31 (all-am): $(INFO_DEPS) replaced by info.
33 2009-09-26 Paul Smith <psmith@gnu.org>
35 * read.c (record_files): Use free_ns() to free struct nameseq.
36 (eval): Ditto.
38 * rule.c (freerule): Use free_dep_chain().
40 * read.c (record_files): Free FILENAMES chain for implicit rules.
41 (eval): Static pattern targets go into the string cache.
43 * function.c (string_glob): Free NAME in the nameseq chain.
45 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
47 * implicit.c (pattern_search): Terminate early if we haven't
48 found any rules to try (performance improvement).
50 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
52 * implicit.c (pattern_search): Merge three parallel arrays,
53 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
54 of struct TRYRULE. In the old version the latter two arrays
55 had insufficient length.
57 2009-09-24 Paul Smith <psmith@gnu.org>
59 * implicit.c (pattern_search): Add back support for order-only
60 prerequisites for secondary expansion implicit rules, that were
61 accidentally dropped. If we find a "|", enable order-only mode
62 and set IGNORE_MTIME on all deps that are seen afterward.
63 (pattern_search): Fix memory leaks: for intermediate files where
64 we've already set the file variable and pattern variable sets, be
65 sure to either save or free them as appropriate.
67 2009-09-23 Paul Smith <psmith@gnu.org>
69 Rework the way secondary expansion is stored, for efficiency.
70 This changes secondary expansion so that ONLY WHEN we know we have
71 a possibility of needing secondary expansion, do we defer the
72 secondary expansion. This means more parsing the deps but we use
73 a lot less memory (due to the strcache). Also, this fixes
74 Savannah bug #18622.
76 * read.c (eval): Don't parse the dep string here anymore.
77 (record_files): Take the dep argument as an unparsed string. If
78 secondary expansion is enabled AND the prereq string has a '$' in
79 it, then set NEED_2ND_EXPANSION and keep the entire string.
80 Otherwise, parse the dep string here to construct the dep list
81 with the names in the strcache.
83 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
84 duplicate the name string (others are in the strcache).
86 * implicit.c: Remove struct idep and free_idep_chain(): unused.
87 (struct patdeps): New structure to store prereq information.
88 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
89 which prerequisites need expansion, and expand only those.
91 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
92 and enter_prereqs(). split_prereqs() takes a fully-expanded string
93 and splits it into a DEP list, handling order-only prereqs.
94 (enter_prereqs): This function enters a list of DEPs into the file
95 database. If there's a stem defined, expand any pattern chars.
96 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
97 set. Use the above functions.
98 (snap_deps): Only perform second expansion on prereqs that need it,
99 as defined by the NEED_2ND_EXPANSION flag.
100 (print_prereqs): New function to print the prereqs
101 (print_file): Call print_prereqs() rather than print inline.
103 * hash.h (STRING_COMPARE): Take advantage of strcache() by
104 comparing pointers.
105 (STRING_N_COMPARE): Ditto.
106 (ISTRING_COMPARE): Ditto.
108 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
109 (parse_file_seq): Return void*
110 * read.c (parse_file_seq): Return void*.
111 (eval): Invoke macroized version of parse_file_seq()
112 * default.c (set_default_suffixes): Ditto.
113 * file.c (split_prereqs): Ditto.
114 * function.c (string_glob): Ditto.
115 * main.c (main): Ditto.
116 * rule.c (install_pattern_rule): Ditto.
118 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
120 2009-09-16 Paul Smith <psmith@gnu.org>
122 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
123 convert to macros.
124 * dep.h: Create alloc_dep() / free_dep() macros.
126 * implicit.c (pattern_search): Take advantage of the new
127 parse_file_seq() to add the directory prefix to each prereq.
129 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
130 all. Avoid reversing chains. Support adding prefixes.
131 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
132 cached/non-cached results.
133 (eval): Remove multi_glob() & invoke new parse_file_seq().
134 * rule.c (install_pattern_rule): Ditto.
135 * main.c (main): Ditto.
136 * implicit.c (pattern_search): Ditto.
137 * function.c (string_glob): Ditto.
138 * file.c (parse_prereqs): Ditto.
139 * default.c (set_default_suffixes): Ditto.
141 * variable.c (parse_variable_definition): Don't run off the end of
142 the string if it ends in whitespace (found with valgrind).
144 * commands.c (set_file_variables): Keep space for all targets in
145 $? if -B is given (found with valgrind).
147 2009-09-15 Paul Smith <psmith@gnu.org>
149 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
150 (xcalloc): Add new function.
151 * make.h: New declarations.
153 * ar.c (ar_glob_match): New calling method for concat().
154 * main.c (main): Ditto.
155 (decode_env_switches): Ditto.
156 * read.c (eval_makefile): Ditto.
157 (tilde_expand): Ditto.
158 (parse_file_seq): Ditto.
159 * variable.c (target_environment): Ditto.
160 (sync_Path_environment): Ditto.
162 * ar.c (ar_glob_match): Use xcalloc().
163 * dir.c (file_impossible): Ditto.
164 * file.c (enter_file): Ditto.
165 * job.c (new_job): Ditto.
166 * read.c (parse_file_seq): Ditto.
167 * vmsfunctions.c (opendir): Ditto.
169 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
171 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
172 inside the loop that looks up environment for PATH.
174 2009-08-31 Eli Zaretskii <eliz@gnu.org>
176 * function.c (windows32_openpipe): Update envp after calling
177 sync_Path_environment.
179 2009-08-02 Paul Smith <psmith@gnu.org>
181 * remake.c (notice_finished_file): Ensure file->cmds is not null
182 before looping through them. Fixes Savannah bug #21824.
184 * doc/make.texi (Wildcard Examples): Clarify when objects is
185 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
186 (Include): Clarify the behavior of -include.
187 Fixes Savannah bug #18963.
189 2009-08-01 Paul Smith <psmith@gnu.org>
191 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
192 etc. come on the command line. Fixes Savannah bug #27093.
194 * expand.c (expand_argument): If the argument is large enough use
195 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
197 * variable.c (do_variable_definition): Avoid using alloca() to
198 hold values, which can be large. Fixes Savannah bug #23960.
200 * job.c (new_job): Use memmove() instead of strcpy() since both
201 pointers are in the same memory block. Fixes Savannah bug #27148.
202 Patch by Petr Machata.
204 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
206 * job.c (construct_command_argv_internal): Add "ulimit" and
207 "unset" to the sh_cmds for Unixy shells.
209 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
211 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
212 that set make_cv_sys_gnu_glob, so they are also correctly set
213 when the cache has been populated before.
215 2009-07-04 Eli Zaretskii <eliz@gnu.org>
217 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
218 exist, as realpath(3) does where it's supported.
220 2006-07-04 Eli Zaretskii <eliz@gnu.org>
222 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
223 (abspath): Support systems that define HAVE_DOS_PATHS (have
224 drive letters in their file names). Use IS_PATHSEP instead of a
225 literal '/' comparison. Fixes Savannah bug #26886.
227 2009-06-14 Paul Smith <psmith@gnu.org>
229 * remake.c (update_file_1): Remember the original file we marked
230 as updating, so we can clear that flag again. If we find a target
231 via vpath, FILE might change.
232 (check_dep): Ditto. Fixes Savannah bug #13529.
233 Patch by Reid Madsen <reid.madsen@tek.com>.
235 2009-06-13 Paul Smith <psmith@gnu.org>
237 * doc/make.texi (MAKEFILES Variable): Be explicit that files
238 included by MAKEFILES cannot give default goals.
239 * read.c (eval): If set_default is not set, pass the no-default-goal
240 value when we read included makefiles. Fixes Savannah bug #13401.
242 * ar.c (ar_name): Ensure that targets with empty parens aren't
243 considered archive member references: archive members must have a
244 non-empty "member" string. Fixes Savannah bug #18435.
246 * function.c (string_glob): Rely on multi_glob() to determine
247 whether files exist or not. Remove call to file_exists_p() which
248 is not always correct. Fixes Savannah bug #21231.
249 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
250 then only files that really exist will be returned.
251 * dep.h: Add new argument to multi_glob().
252 * rule.c (install_pattern_rule): Ditto.
253 * read.c (eval): Ditto.
254 * main.c (main): Ditto.
255 * implicit.c (pattern_search): Ditto.
256 * file.c (parse_prereqs): Ditto.
257 * default.c (set_default_suffixes): Ditto.
259 2009-06-09 Paul Smith <psmith@gnu.org>
261 * commands.c (set_file_variables): If always_make_flag is set,
262 always add the prereq to $?. Fixes Savannah bug #17825.
264 * remake.c (update_file_1): When rebuilding deps of FILE, also try
265 to rebuild the deps of all the also_make targets for that file.
266 Fixes Savannah bug #19108.
268 * implicit.c (pattern_search): Undo test for is_target, added by
269 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
270 Rule Search Algorithm". Fixes Savannah bug #17752.
272 * main.c (clean_jobserver): Clear the jobserver_fds options and
273 set job_slots to the default when we clean up.
274 (define_makeflags): Return the new MAKEFLAGS value.
275 (main): Reset MAKEFLAGS in the environment when we re-exec.
276 Fixes Savannah bug #18124.
278 2009-06-08 Paul Smith <psmith@gnu.org>
280 * read.c (eval): Collapse continuations post-semicolon on target-
281 specific variables. Fixes Savannah bug #17521.
283 2009-06-07 Paul Smith <psmith@gnu.org>
285 * job.c (reap_children): For older systems without waitpid() (are
286 there any of these left?) run wait(2) inside EINTRLOOP to handle
287 EINTR errors. Fixes Savannah bug #16401.
289 * (various): Debug message cleanup. Fixes Savannah bug #16469.
291 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
293 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
294 not the end, to catch second expansion $(eval ...) defining new
295 target/prereq relationships during snap_deps.
296 Fixes Savannah bug #24622.
298 * read.c (record_files): The second-expansion "f->updating" hack
299 was not completely correct: if assumed that the target with
300 commands always had prerequisites; if one didn't then the ordering
301 was messed up. Fixed for now to use f->updating to decide whether
302 to preserve the last element in the deps list... but this whole
303 area of constructing and reversing the deps list is too confusing
304 and needs to be reworked. Fixes Savannah bug #21198.
306 2009-06-06 Paul Smith <psmith@gnu.org>
308 * hash.c (hash_insert): Remove useless test for NULL.
309 Fixes Savannah bug #21823.
311 * make.h: Move SET_STACK_SIZE determination to make.h.
312 * main.c (main): New global variable, STACK_LIMIT, holds the
313 original stack limit when make was started.
314 * job.c (start_job_command): Reset the stack limit, if we changed it.
315 Fixes Savannah bug #22010.
317 * remake.c (check_dep): Only set the target's state to not-started
318 if it's not already running. Found this while testing -j10 builds
319 of glibc: various targets were being rebuilt multiple times.
320 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
321 bug #15919.
323 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
324 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
325 Bugzilla bug 10246.
327 2009-06-04 Paul Smith <psmith@gnu.org>
329 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
331 * maintMakefile: Modify access of config and gnulib Savannah
332 modules to use GIT instead of CVS.
334 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
335 Fixes Savannah bug #24655.
337 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
338 this can happen during some invocations of $(eval ...) for example.
339 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
341 2009-06-02 Paul Smith <psmith@gnu.org>
343 * configure.in: Check for fileno()
344 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
345 for the makefile file so invocations of $(shell ...) don't inherit it.
346 Fixes Savannah bug #24277.
348 2009-06-01 Paul Smith <psmith@gnu.org>
350 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
351 expansion was handled incorrectly. Rework the default goal
352 handling to save the variable only. Remove default_goal_file and
353 default_goal_name.
354 * read.c (eval): Check default_goal_var, not default_goal_name.
355 * read.c (record_target_var): Don't check default_goal_file here.
357 2009-05-31 Paul Smith <psmith@gnu.org>
359 * main.c (main): Expand the .DEFAULT_GOAL variable before using
360 it, and if the multi_glob() returns nothing (say it expanded to
361 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
363 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
364 $(and ..) to the reference. Fixes Savannah bug #25694.
366 * make.1: Be clear that some recipes will be executed even with -n.
367 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
369 * doc/make.texi (Override Directive): Make more clear how
370 overrides and appends interact.
371 Elucidates part of Savannah bug #26207.
373 * read.c (record_target_var): Don't reset the origin on
374 target-specific variables; try_variable_definition() will handle
375 this correctly. Fixes Savannah bug #26207.
377 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
378 Fixes Savannah bug #25712.
380 * implicit.c (pattern_search): Keep a pointer to the beginning of
381 the filename and save that instead of the constructed pointer.
382 Fixes Savannah bug #26593.
383 Patch by Mark Seaborn <mrs@mythic-beasts.com>
385 2009-05-30 Paul Smith <psmith@gnu.org>
387 * doc/make.texi (Multi-Line): Add a description of the new abilities
388 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
389 "command sequence" vs. "recipe" syntax.
390 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
391 after a define, to create variables with those flavors.
393 2009-05-25 Paul Smith <psmith@gnu.org>
395 Reworked the parser for variable assignments to allow multiple
396 modifiers, and in any order. Also allows variable and
397 prerequisites to be modifier names ('export', 'private', etc.)
399 * NEWS: Add notes about user-visible changes.
401 * read.c (struct vmodifiers): Remember what modifiers were seen.
402 (parse_var_assignment): New function to parse variable assignments.
403 (eval): Call the new function. Handle variable assignments earlier.
405 * variable.c (parse_variable_definition): Only parse; don't create var.
406 (assign_variable_definition): Call parse, then create the var.
408 2009-05-24 Paul Smith <psmith@gnu.org>
410 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
411 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
413 2009-03-14 Eli Zaretskii <eliz@gnu.org>
415 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
416 Fixes Savannah bug #25412.
418 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
419 prototype for xmalloc.
420 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
421 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
422 Loop over an array of extensions, instead of duplicating the same
423 code inline. Use SearchPath followed by CreateFile, instead of
424 the obsolete OpenFile. Fixes Savannah bug #17277.
425 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
426 to `find_file'. Fixes Savannah bug #25662.
428 2009-03-07 Eli Zaretskii <eliz@gnu.org>
430 * function.c (func_shell): Don't close pipedes[1] if it is -1.
431 Fixes Savannah bug #20495.
433 2009-02-28 Ralf Wildenhues <address@hidden>
435 * doc/make.texi (Instead of Execution): Document interaction of
436 -t with phony targets.
438 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
440 Introduce a new keyword "private" which applies to target-specific
441 variables and prevents their values from being inherited.
443 * variable.h (struct variable): Add private_var flag to each variable.
444 Add a flag to specify which list entry switches to the parent target.
445 * variable.c (define_variable_in_set): Initialize private_var flag.
446 (lookup_variable): Skip private variables in parent contexts.
447 (initialize_file_variables): Set next_is_parent appropriately.
448 (print_variable): Show the private_var flag.
449 * read.c (eval): Recognize the private keyword.
450 (record_target_var): Set private_var.
451 * doc/make.texi (Suppressing Inheritance): Add documentation.
453 2008-10-26 Paul Smith <psmith@gnu.org>
455 * configure.in: Check for strndup().
456 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
457 if it's available.
458 * make.h: Rename savestring to xstrndup.
459 * commands.c (chop_commands): Ditto.
460 * function.c (func_foreach): Ditto.
461 * read.c (eval, record_files): Ditto.
462 * variable.c (define_variable_in_set): Ditto.
464 2008-09-30 Eli Zaretskii <eliz@gnu.org>
466 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
467 "-gstabs+ -ggdb3".
469 * w32/subproc/build.bat (GCCBuild): Likewise.
471 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
473 * job.c (construct_command_argv_internal): Avoid extra backslash
474 in batch-mode Unixy shells. Under DB_JOBS, display the contents
475 of the batch file.
477 2008-05-31 Eli Zaretskii <eliz@gnu.org>
479 * README.W32.template: Remove obsolete text about non-support for
480 -jN without Unixy shell. Remove obsolete text about not supplying
481 Visual Studio project files (we do supply them). Modify text to
482 prefer GCC builds to MSC builds.
484 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
486 * doc/make.texi (Empty Targets): Fix typo.
488 2008-03-27 Paul Smith <psmith@gnu.org>
490 Fix Savannah bug #22379:
491 * ar.c (ar_glob_match): Zero the allocated structure.
492 * read.c (parse_file_seq): Ditto.
494 2008-03-08 Brian Dessent <brian@dessent.net>
496 * maintMakefile: Update Translation Project location.
498 2008-01-26 Eli Zaretskii <eliz@gnu.org>
500 * variable.c (target_environment): Don't use shell_var if its
501 `value' field is NULL.
503 2007-12-22 Eli Zaretskii <eliz@gnu.org>
505 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
507 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
508 (TEXINFOS): Value changed to `doc/make.texi'.
509 (.SUFFIXES): Use .texi instead of .texinfo.
510 (make.info, make.dvi): Depend on doc/make.texi.
511 (.texi.info): New target, instead of ".texinfo.info". Change -I
512 switch to $(MAKEINFO) to look in doc/. Use --no-split.
513 (.texi): New target, instead of ".texinfo". Change -I switch to
514 $(MAKEINFO) to look in doc/. Use --no-split.
515 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
516 switch to $(MAKEINFO) to look in doc/.
517 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
518 "*.i[0-9][0-9]" (due to --no-split above).
519 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
520 (html, make_1.html): New targets.
521 (.PHONY): Add "html".
522 (.SUFFIXES): Add .html.
524 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
526 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
527 HAVE_DECL_SYS_SIGLIST.
529 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
530 build does not use child_execute_job.
532 * variable.c (define_automatic_variables) [__MSDOS__]: Always
533 export the SHELL environment variable to the child.
535 2007-12-22 Eli Zaretskii <eliz@gnu.org>
537 * config.h.W32: Include sys/types.h.
538 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
540 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
541 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
542 also `:'.
544 2007-11-04 Paul Smith <psmith@gnu.org>
546 * doc/make.texi: Convert references to "commands", "command
547 lines", and "command script" to "recipe".
548 * NEWS: Ditto.
549 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
550 Ditto.
552 2007-10-27 Bruno Haible <bruno@clisp.org>
554 * remake.c (f_mtime): Print time difference values between 100 and
555 ULONG_MAX in fixed-point notation rather than in exponention notation.
557 2007-10-12 Eli Zaretskii <eliz@gnu.org>
559 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
560 a more complex value than a simple shell: if it's not a default
561 shell now then expand it and see if is a default shell then.
563 2007-10-10 Eli Zaretskii <eliz@gnu.org>
565 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
566 pathnames, with const strings.
567 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
568 from the template (used for building from CVS, not a dist).
570 2007-10-10 Paul Smith <psmith@gnu.org>
572 * make.h: Add a prototype for w32_kill() (change suggested by

585 Provided by Diego Biurrun <diego@biurrun.de>
587 2007-09-11 Paul Smith <psmith@gnu.org>
589 * doc/make.texi (Special Variables): Moved this into the "How to
590 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
591 (MAKEFILE_LIST) No longer a section; this was added into the
592 "Special Variables" section.
593 (Rule Introduction): Reference .RECIPEPREFIX.
594 (Simple Makefile): Ditto.
595 (Rule Syntax): Ditto.
596 (Command Syntax): Ditto.
597 (Error Messages): Ditto.
599 2007-09-10 Paul Smith <psmith@gnu.org>
601 * commands.c (print_commands): Don't print an extra line in the
602 command scripts. Prefix the command scripts with cmd_prefix, not \t.
604 * read.c (construct_include_path): Add the full string to the cache; we
605 were chopping the last char.
607 * NEWS: Announce the .RECIPEPREFIX special variable.
608 * variable.c (lookup_special_var): Rename from handle_special_var().
609 (lookup_variable): Call the new name.
610 (set_special_var): New function: handle setting of special variables.
611 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
612 (do_variable_definition): Call it.
613 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
614 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
615 * main.c (main): Create the .RECIPEPREFIX special variable.
616 * read.c (eval): Remove the cmd_prefix characters from the command
617 scripts here, so they're not stored in the commands array at all,
618 rather than waiting and stripping them out during command construction.
619 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
621 2007-08-15 Paul Smith <psmith@gnu.org>
623 * doc/make.texi (GNU Free Documentation License): The fdl.texi
624 file has had the section info removed, so add some to make.texi
625 before we include it.
627 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
629 * remake.c (check_dep): Reset the target state for intermediate
630 files. They might have been considered before but not updated
631 then (order-only for example) but they will be this time.
632 Fixes Savannah bug #'s 3330 and 15919.
634 2007-07-21 Eli Zaretskii <eliz@gnu.org>
636 Fix Savannah bug #20549:
637 * function.c (func_shell): Call construct_command_argv with zero
638 value of FLAGS.
639 * job.c (construct_command_argv_internal): New argument FLAGS; all
640 callers changed.
641 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
642 just_print_flag.
643 * job.h (construct_command_argv_internal): Update prototype.
645 2007-07-13 Paul Smith <psmith@gnu.org>
647 * file.c (expand_deps): Use variable_buffer as the start of the
648 buffer, not the original pointer (in case it was reallocated).
649 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
650 Fixes Savannah bug #20452.
652 2007-07-04 Paul Smith <psmith@gnu.org>
654 * (ALL FILES): Update to GPLv3.
655 * (ALL FILES): Update copyright for 2007.

659 2007-06-29 Thiemo Seufer <ths@mips.com>
661 * maintMakefile: Update Translation Project location.
663 2007-06-13 Paul Smith <psmith@gnu.org>

667 Fixes Savannah bug #20018.
669 * expand.c (variable_expand_for_file): Preserve the value of
670 reading_file rather than setting it to 0 at the end.
671 Fixes Savannah bug #20033.
673 2007-05-11 Paul Smith <psmith@gnu.org>
675 * job.c (new_job): Add debug info to specify where make found the
676 command script it is running to build a target.
677 Fixes Savannah bug #18617.
679 * default.c (default_suffixes,default_suffix_rules,default_variables):
680 Add support for Objective C. Fixes Savannah bug #16389.
681 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
683 * function.c (func_lastword): Initialize p.
685 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
686 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
687 Dave Korn <dave.korn@artimi.com>
689 2007-05-08 Paul Smith <psmith@gnu.org>
691 Fix Savannah bug #19656:
693 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
695 * make.h: Change all case-insensitive string compares to use
696 strcasecmp() (from POSIX). If we don't have that but do have one
697 of the others, define strcasecmp to be one of those instead. If
698 we don't have any, declare a prototype for our own version.
700 * misc.c (strcasecmp): Use this if we can't find any native
701 case-insensitive string comparison function.
702 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
703 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
704 strcmpi().
705 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
706 strcasecmp() instead of stricmp().
707 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
708 instead of strcmpi().
709 * acinclude.m4: Remove the strcasecmp() check from here.
711 2007-03-21 Paul Smith <psmith@gnu.org>
713 * configure.in: Don't turn on case-insensitive file system support
714 if --disable-... is given. Fixes Savannah bug #19348.
716 2007-03-19 Paul Smith <psmith@gnu.org>
718 * ALL: Use the strcache for all file name strings, or other
719 strings which we will never free. The goal is to save memory by
720 avoiding duplicate copies of strings. However, at the moment this
721 doesn't save much memory in most situations: due to secondary
722 expansion we actually save prerequisite lists twice (once before
723 the secondary expansion, and then again after it's been parsed
724 into individual file names in the dep list). We will resolve this
725 in a future change, by doing the parsing up-front for targets
726 where secondary expansion is not set.
728 Moving things into the strcache also allows us to use const
729 pointers in many more places.
731 2007-01-03 Paul Smith <psmith@gnu.org>
733 * make.h (ENULLLOOP): Reset errno after each failed invocation of
734 the function, not just the first. Fixes Savannah bug #18680.
736 2006-11-18 Paul Smith <psmith@gnu.org>
738 * strcache.c (strcache_add_len): Don't allocate a new buffer
739 unless the string is not already nil-terminated. Technically this
740 is a violation of the standard, since we may be passed an array
741 that is not long enough to test one past. However, in make this
742 is never true since we only use nil-terminated strings or
743 sub-strings thereof.
745 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
747 * main.c: New global cmd_prefix, defaults to '\t'.
748 * job.c (construct_command_argv_internal): Use cmd_prefix instead
749 of '\t'.
751 * dir.c: Constified.
752 (dir_contents_file_exists_p): Check for an error return from
753 readdir(), just in case.
755 * commands.c: Constified.
756 * default.c: Constified.
757 * expand.c: Constified.
758 * function.c: Partial constification.
759 * variable.c: Partial constification.
760 * vmsify.c: Constification. Hard to test this but I hope I didn't
761 screw it up!
762 * vpath.c: Partial constification.
763 * w32/pathstuff.c: Partial constification.
765 2006-11-16 Eli Zaretskii <eliz@gnu.org>
767 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
768 backslashes and drive letters as absolute.
770 2006-10-22 Paul Smith <psmith@gnu.org>
772 * main.c (struct command_switch): Use const and void*.
774 2006-10-21 Paul Smith <psmith@gnu.org>
776 * ar.c: Constified.
777 * arscan.c: Constified.
779 2006-09-30 Paul Smith <psmith@gnu.org>
781 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
782 point to lastword since the example was updated.
783 Fixes Savannah bug #16304.
784 (Secondary Expansion): Correct example description.
785 Fixes Savannah bug #16468.
786 (Makefile Contents): Clarify that comments cannot appear within
787 variable references or function calls.
788 Fixes Savannah bug #16577.
789 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
790 Fixes Savannah bug #17701.
791 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
792 (Prerequisite Types): Added an example of using order-only
793 prerequisites. Fixes Savannah bug #17880.
794 (Rule Syntax): "lise" -> "list"
795 (Multiple Rules): ... -> @dots{}
796 (Splitting Lines): ditto.
798 * remake.c (update_file_1): Prereqs that don't exist should be
799 considered changed, for the purposes of $?.
800 Fixes Savannah bug #16051.
802 * make.1: Remove extraneous "+".
803 Fixes Savannah bug #16652.

807 * configure.in: Include sys/types.h when checking for sys/wait.h.
809 2006-08-18 Eli Zaretskii <eliz@gnu.org>
811 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
812 $PATH_SEPARATOR.
814 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
815 Normally, it is defined in config.h.
817 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
818 well.
820 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
821 sh_chars_sh for Windows platforms that emulate Unix.
823 2006-05-07 Paul D. Smith <psmith@gnu.org>
825 * README.OS2.template: Updates provided by Andreas Buening
826 <andreas.buening@nexgo.de>.
828 2006-04-30 Paul D. Smith <psmith@gnu.org>
830 * make.h: Include <direct.h> if HAVE_DIRECT_H.
831 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
833 2006-04-26 Paul D. Smith <psmith@gnu.org>
835 * README.cvs: Add a reminder to notify the GNU translation robot.
837 * doc/make.texi: Change @direcategory (requested by Karl Berry).
839 2006-04-20 Paul D. Smith <psmith@gnu.org>
841 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
842 that don't have extended grep.
843 (cvsclean): Use $(PERL) instead of perl.
845 2006-04-09 Paul D. Smith <psmith@gnu.org>
847 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
849 * expand.c, implicit.c, main.c, read.c: Rename variables so that
850 inner-scope variables don't mask outer-scope variables.
852 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
853 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
854 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
855 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
856 values from memory allocation functions: they return void* and so
857 don't need to be cast. Also remove (char *) casts of arguments to
858 xrealloc().
860 * configure.in: Remove checks for memcpy/memmove/strchr.
862 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
864 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp
865 calls to memset/memcpy/memmove/memcmp calls.
866 * expand.c, file.c, function.c, getloadavg.c, implicit.c: Ditto.
867 * job.c, main.c, misc.c, read.c, remake.c, rule.c: Ditto.
868 * variable.c, vpath.c: Ditto.
870 * make.h (EXIT_FAILURE): Should be 1, not 0.
872 2006-04-06 Paul D. Smith <psmith@gnu.org>
874 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
875 require an ISO C 1989 standard compiler and runtime library.
877 * Makefile.am: Remove the ansi2knr feature.
879 * make.h: Remove the PARAMS() macro definition and all uses of it.
881 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
882 * commands.c, commands.h, config.h-vms.template: Ditto.
883 * dep.h, dir.c, expand.c, filedef.h, function.c: Ditto.
884 * implicit.c, job.c, job.h, main.c, read.c, remake.c: Ditto.
885 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
887 * NEWS: Update.
889 2006-04-01 Paul D. Smith <psmith@gnu.org>
891 Version 3.81 released.
893 * NEWS: Updated for 3.81.
895 * README.cvs: Mention that vpath builds are not supported out of
896 CVS. Fixes Savannah bug #16236.
897 Remove update of make.texi from the list of things to do; we use
898 version.texi now.
900 2006-03-26 Paul D. Smith <psmith@gnu.org>
902 * doc/make.texi: Clean up licensing. Use @copying and version.texi
903 support from automake, as described in the Texinfo manual.
905 2006-03-25 Eli Zaretskii <eliz@gnu.org>
907 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
908 with lastslash, since the latter points to filename, not to
909 target.
910 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
911 Declare and define sh_chars_sh[].
913 2006-03-23 Paul D. Smith <psmith@gnu.org>
915 * configure.in: Look for build.sh.in in $srcdir so it will be
916 built for remote configurations as well.
918 * Makefile.am: Make sure to clean up build.sh during distclean.
919 Fixes Savannah bug #16166.
921 * misc.c (log_access): Takes a const char *.
922 * function.c (fold_newlines): Takes an unsigned int *.
923 Both fixes for Savannah bug #16170.
925 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
927 * implicit.c (pattern_search): Call set_file_variables only
928 if we have prerequisites that need second expansion. Fixes
929 Savannah bug #16140.
931 2006-03-19 Paul D. Smith <psmith@gnu.org>
933 * remake.c (update_file): Add alloca(0) to clean up alloca'd
934 memory on hosts that don't support it directly.
936 * README.cvs: Add information on steps for making a release (to
937 make sure I don't forget any).
939 * main.c (clean_jobserver): Move jobserver cleanup code into a new
940 function.
941 (die): Cleanup code was removed from here; call the new function.
942 (main): If we are re-execing, clean up the jobserver first so we
943 don't leak file descriptors.
944 Reported by Craig Fithian <craig.fithian@citigroup.com>
946 2006-03-17 Paul D. Smith <psmith@gnu.org>
948 * maintMakefile (do-po-update): Rewrite this rule to clean up and
949 allow multiple concurrent runs.
950 Patch from Joseph Myers <joseph@codesourcery.com>
952 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
954 * dep.h (struct dep): Add the stem field.
955 * misc.c (alloc_dep, free_dep): New functions.
956 (copy_dep_chain): Copy stem.
957 (free_dep_chain): Use free_dep.
958 * read.c (record_files): Store stem in the dependency line.
959 * file.c (expand_deps): Use stem stored in the dependency line. Use
960 free_dep_chain instead of free_ns_chain.
961 * implicit.c (pattern_search): Use alloc_dep and free_dep.
962 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
963 * main.c (main, handle_non_switch_argument): Ditto.
964 * remake.c (check_dep): Ditto.
965 * rule.c (convert_suffix_rule, freerule): Ditto.
967 2006-03-14 Paul D. Smith <psmith@gnu.org>
969 * expand.c (variable_append): Instead of appending everything then
970 expanding the result, we expand (or not, if it's simple) each part
971 as we add it.
972 (allocated_variable_append): Don't expand the final result.
973 Fixes Savannah bug #15913.
975 2006-03-09 Paul Smith <psmith@gnu.org>
977 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
978 listed non-existent files as changed. Turns out there's a bug in
979 the Linux kernel builds which means that this change causes
980 everything to rebuild every time. We will re-introduce this fix
981 in the next release, to give them time to fix their build system.
982 Fixes Savannah bug #16002.
983 Introduces Savannah bug #16051.
985 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
986 we *don't* find UNIX "/".
987 Reported by David Ergo <david.ergo@alterface.com>
989 2006-03-04 Eli Zaretskii <eliz@gnu.org>
991 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
992 locator function find_and_set_default_shell if SHELL came from the
993 command line.
995 2006-02-20 Paul D. Smith <psmith@gnu.org>
997 * variable.c (merge_variable_set_lists): It's legal for *setlist0
998 to be null; don't core in that case.
1000 2006-02-19 Paul D. Smith <psmith@gnu.org>
1002 * commands.c (set_file_variables): Realloc, not malloc, the static
1003 string values to avoid memory leaks.
1005 * expand.c (recursively_expand_for_file): Only set reading_file to
1006 an initialized value.
1008 * implicit.c (pattern_search): We need to make a copy of the stem
1009 if we get it from an intermediate dep, since those get freed.
1011 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1012 begin with ".".
1013 (enter_file) [VMS]: Ditto.
1014 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1016 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1018 * job.c (construct_command_argv_internal): Fix last change.
1020 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1021 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1022 the calls to _beginthreadex.
1024 * expand.c (recursively_expand_for_file): Initialize `save' to
1025 prevent compiler warnings.
1027 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1029 * job.c (construct_command_argv_internal): Don't create a temporary
1030 script/batch file if we are under -n. Call _setmode to switch the
1031 script file stream to text mode.
1033 2006-02-17 Paul D. Smith <psmith@gnu.org>
1035 * variable.c (merge_variable_set_lists): Don't try to merge the
1036 global_setlist. Not only is this useless, but it can lead to
1037 circularities in the linked list, if global_setlist->next in one
1038 list gets set to point to another list which also ends in
1039 global_setlist.
1040 Fixes Savannah bug #15757.
1042 2006-02-15 Paul D. Smith <psmith@gnu.org>
1044 Fix for Savannah bug #106.
1046 * expand.c (expanding_var): Keep track of which variable we're
1047 expanding. If no variable is being expanded, it's the same as
1048 reading_file.
1049 * make.h (expanding_var): Declare it.
1050 * expand.c (recursively_expand_for_file): Set expanding_var to the
1051 current variable we're expanding, unless there's no file info in
1052 it (could happen if it comes from the command line or a default
1053 variable). Restore it before we exit.
1054 * expand.c (variable_expand_string): Use the expanding_var file
1055 info instead of the reading_file info.
1056 * function.c (check_numeric): Ditto.
1057 (func_word): Ditto.
1058 (func_wordlist): Ditto.
1059 (func_error): Ditto.
1060 (expand_builtin_function): Ditto.
1061 (handle_function): Ditto.
1063 2006-02-14 Paul D. Smith <psmith@gnu.org>
1065 * read.c (eval): Even if the included filenames expands to the
1066 empty string we still need to free the allocated buffer.
1068 * implicit.c (pattern_search): If we allocated a variable set for
1069 an impossible file, free it.
1070 * variable.c (free_variable_set): New function.
1071 * variable.h: Declare it.
1073 * read.c (read_all_makefiles): Makefile names are kept in the
1074 strcache, so there's never any need to alloc/free them.
1075 (eval): Ditto.
1077 * main.c (main): Add "archives" to the .FEATURES variable if
1078 archive support is enabled.
1079 * doc/make.texi (Special Variables): Document it.
1081 2006-02-13 Paul D. Smith <psmith@gnu.org>
1083 * implicit.c (pattern_search): Add checking for DOS pathnames to
1084 the pattern rule target LASTSLASH manipulation.
1085 Fixes Savannah bug #11183.
1087 2006-02-11 Paul D. Smith <psmith@gnu.org>
1089 * (ALL FILES): Updated copyright and license notices.
1091 2006-02-10 Paul D. Smith <psmith@gnu.org>
1093 A new internal capability: the string cache is a read-only cache
1094 of strings, with a hash table interface for fast lookup. Nothing
1095 in the cache will ever be freed, so there's no need for reference
1096 counting, etc. This is the beginning of a full solution for
1097 Savannah bug #15182, but for now we only store makefile names here.
1099 * strcache.c: New file. Implement a read-only string cache.
1100 * make.h: Add prototypes for new functions.
1101 * main.c (initialize_global_hash_tables): Initialize the string cache.
1102 (print_data_base): Print string cache stats.
1103 * read.c (eval_makefile): Use the string cache to store makefile
1104 names. Rewrite the string allocation to be sure we free everything.
1106 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1108 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1109 directory time stamp didn't change, except on FAT filesystems.
1110 Suggested by J. David Bryan <jdbryan@acm.org>.
1112 2006-02-09 Paul D. Smith <psmith@gnu.org>
1114 * function.c (func_or): Implement a short-circuiting OR function.
1115 (func_and): Implement a short-circuiting AND function.
1116 (function_table_init): Update the table with the new functions.
1117 * doc/make.texi (Conditional Functions): Changed the "if" section
1118 to one on general conditional functions. Added documentation for
1119 $(and ...) and $(or ...) functions.
1120 * NEWS: Note new $(and ...) and $(or ...) functions.
1122 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1124 * job.h (struct child): Add the dontcare bitfield.
1125 * job.c (new_job): Cache dontcare flag.
1126 * job.c (reap_children): Use cached dontcare flag instead of the
1127 one in struct file. Fixes Savannah bug #15641.
1129 2006-02-06 Paul D. Smith <psmith@gnu.org>
1131 * vpath.c (selective_vpath_search): If the file we find has a
1132 timestamp from -o or -W, use that instead of the real time.
1133 * remake.c (f_mtime): If the mtime is a special token from -o or
1134 -W, don't overwrite it with the real mtime.
1135 Fixes Savannah bug #15341.
1137 Updates from Markus Mauhart <qwe123@chello.at>:
1139 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1140 (process_signal, process_last_err, process_exit_code): Manage
1141 invalid handle values.
1142 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1143 manage invalid handles; remove them.

1151 to avoid walking the list every time we want to add a new one.
1152 Fixes Savannah bug #15533.
1153 * filedef.h (struct file): Add a new LAST pointer.
1155 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1156 the comparison. For 64-bits systems the result of the subtraction
1157 might not fit into an int. Use comparison instead.
1158 Fixes Savannah bug #15534.
1160 * doc/make.texi: Update the chapter on writing commands to reflect
1161 the changes made in 3.81 for backslash/newline and SHELL handling.
1163 2006-02-01 Paul D. Smith <psmith@gnu.org>
1165 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1176 J. Grant <jg@jguk.org>.
1178 * main.c: Update the copyright year in the version output.
1179 * prepare_w32.bat: Remove this file from the distribution.
1181 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1183 * remake.c (update_goal_chain): Set g->changed instead of
1184 incrementing it, as it is only 8-bit wide, and could overflow if
1185 many commands got started in update_file.
1187 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1189 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1190 MAXIMUM_WAIT_OBJECTS.
1191 (process_wait_for_any_private): Change dimension of handles[]
1192 array to MAXIMUM_WAIT_OBJECTS.
1193 (process_used_slots): New function.
1194 (process_register): Don't register more processes than the
1195 available number of slots.
1196 (process_easy): Don't start new processes if all slots are used up.
1198 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1199 are already more children than sub_proc.c can handle, behave as if
1200 the load were too high.
1201 (start_job_command): Fix a typo in error message when process_easy
1202 fails.
1204 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1206 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1207 the shell is not sh.exe.
1209 * job.c (create_batch_file): Renamed from create_batch_filename;
1210 all callers changed. Don't close the temporary file; return its
1211 file descriptor instead. New arg FD allows to return the file
1212 descriptor.
1213 (construct_command_argv_internal): Use _fdopen instead of fopen to
1214 open the batch file.
1216 2006-01-04 Paul D. Smith <psmith@gnu.org>
1218 * readme.vms: Updates for case-insensitive VMS file systems from
1219 Hartmut Becker <Hartmut.Becker@hp.com>.

1231 doesn't exist.
1233 * read.c (eval): Be sure to strip off trailing whitespace from the

1239 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1240 disable warnings for MSC.
1241 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1243 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1245 * doc/make.texi (Execution): Add a footnote about changes in
1246 handling of backslash-newline sequences. Mention the differences
1247 on MS-DOS and MS-Windows.
1249 * NEWS: More details about building the MinGW port and a pointer
1250 to README.W32. Fix the section name that describes the new
1251 backward-incompatible processing of backslash-newline sequences.
1252 The special processing of SHELL set to "cmd" is only relevant to
1253 MS-Windows, not MS-DOS.
1255 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1257 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1258 to DWORD, to avoid compiler warnings.
1259 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1260 use %ld in format, to avoid compiler warnings.
1262 * doc/make.texi (Special Targets): Fix a typo.
1263 (Appending): Fix cross-reference to Setting.
1264 (Special Variables, Secondary Expansion, File Name Functions)
1265 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1266 periods after a sentence.
1267 (Execution): Add @: after "e.g.".
1268 (Environment): Fix punctuation.
1269 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1270 (Shell Function, Target-specific): Add @: after "vs."
1272 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1274 * read.c (record_target_var): Initialize variable's export field
1275 with v_default instead of leaving it "initialized" by whatever
1276 garbage happened to be on the heap.
1278 2005-12-12 Paul D. Smith <psmith@gnu.org>
1280 * make.1: Fix some display errors and document all existing options.
1281 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1283 2005-12-11 Paul D. Smith <psmith@gnu.org>
1285 * implicit.c (pattern_search): If 2nd expansion is not set for
1286 this implicit rule, replace the pattern with the stem directly,
1287 and don't re-expand the variable list. Along with the other
1288 .SECONDEXPANSION changes below, fixes bug #13781.
1290 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1292 * implicit.c (pattern_search): Mark other files that this rule
1293 builds as targets so that they are not treated as intermediates
1294 by the pattern rule search algorithm. Fixes bug #13022.
1296 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1298 * remake.c (notice_finished_file): Propagate the change of

1311 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1312 variable.
1313 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1314 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1316 2005-10-26 Paul Smith <psmith@gnu.org>
1318 * read.c (record_files): Don't set deps flags if there are no deps.
1319 * maintMakefile: We only need to build the templates when we are
1320 creating a distribution, so don't do it for "all".
1322 2005-10-24 Paul D. Smith <psmith@gnu.org>
1324 Make secondary expansion optional: its enabled by declaring the
1325 special target .SECONDEXPANSION.
1327 * NEWS: Update information on second expansion capabilities.
1328 * doc/make.texi (Secondary Expansion): Document the
1329 .SECONDEXPANSION special target and its behavior.

1331 prerequisite list was found in a static pattern rule.
1332 (free_dep_chain): Declare a prototype.
1333 * file.c (parse_prereqs): New function: break out some complexity
1334 from expand_deps().
1335 (expand_deps): If we aren't doing second expansion, replace % with
1336 the stem for static pattern rules. Call the new function.
1337 * filedef.h (parse_prereqs): Declare a prototype.
1338 * implicit.c (pattern_search): Initialize the new staticpattern
1339 field.
1340 * main.c (second_expansion): Declare a global variable to remember
1341 if the special target has been seen. Initialize the new
1342 staticpattern field for prerequisites.
1343 * make.h: Extern for second_expansion.
1344 * misc.c (free_dep_chain): New function: frees a struct dep list.
1345 * read.c (read_all_makefiles): Initialize the staticpattern field.
1346 (eval_makefile): Ditto.
1347 (record_files): Check for the .SECONDEXPANSION target and set
1348 second_expansion global if it's found.
1349 Use the new free_dep_chain() instead of doing it by hand.
1350 Set the staticpattern field for prereqs of static pattern targets.
1352 2005-10-16 Paul D. Smith <psmith@gnu.org>
1354 * main.c (main): Set CURDIR to be a file variable instead of a
1355 default, so that values of CURDIR inherited from the environment
1356 won't override the make value.
1358 2005-09-26 Paul D. Smith <psmith@gnu.org>
1360 * job.c (construct_command_argv_internal): If the line is empty
1361 remember to free the temporary argv strings.
1362 Fixes bug # 14527.
1364 2005-09-16 Paul D. Smith <psmith@gnu.org>
1366 * job.c (start_job_command): The noerror flag is a boolean (single
1367 bit); set it appropriately.
1368 Reported by Mark Eichin <eichin@metacarta.com>
1370 2005-08-29 Paul D. Smith <psmith@gnu.org>
1372 * function.c (func_error): On Windows, output from $(info ...)
1373 seems to come in the wrong order. Try to force it with fflush().
1375 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1377 * read.c (record_files): Move code that sets stem for static
1378 pattern rules out of the if (!two_colon) condition so it is
1379 also executed for two-colon rules. Fixes Savannah bug #13881.
1381 2005-08-08 Paul D. Smith <psmith@gnu.org>
1383 * make.h: Don't test that __STDC__ is non-0. Some compilers
1384 (Windows for example) set it to 0 to denote "ISO C + extensions".
1385 Fixes bug # 13594.
1387 2005-08-07 Paul D. Smith <psmith@gnu.org>
1389 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1390 conditional (slightly different version of a fix from Eli).
1392 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1393 If make is running in parallel without -k and two jobs die in a
1394 row, but not too close to each other, then make will quit without
1395 waiting for the rest of the jobs to die.
1397 * main.c (die): Don't reset err before calling reap_children() the
1398 second time: we still want it to be in the error condition.
1399 * job.c (reap_children): Use a static variable, rather than err,
1400 to control whether or not the error message should be printed.
1402 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1404 * w32/subproc/sub_proc.c: Include signal.h.
1405 (process_pipe_io, process_file_io): Pass a pointer to a local
1406 DWORD variable to GetExitCodeProcess. If the exit code is
1407 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1409 * job.c [WINDOWS32]: Include windows.h.
1410 (main_thread) [WINDOWS32]: New global variable.
1411 (reap_children) [WINDOWS32]: Get the handle for the main thread
1412 and store it in main_thread.
1414 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1415 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1416 doing anything else. When we are done, close the main thread
1417 handle and exit with status 130.
1419 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1421 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1422 pointer to fprintf.
1424 * main.c (find_and_set_default_shell): If found a DOSish shell,
1425 set sh_found and the value of default_shell, and report the
1426 findings in debug mode.
1428 * job.c (construct_command_argv_internal): Check unixy_shell, not
1429 no_default_sh_exe, to decide whether to use Unixy or DOSish
1430 builtin commands.
1432 * README.W32: Update with info about the MinGW build.
1434 * build_w32.bat: Support MinGW.
1436 * w32/subproc/build.bat: Likewise.
1438 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1439 printing DWORD args.
1441 * function.c (windows32_openpipe): Fix format strings for printing
1442 DWORD args.
1444 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1445 'reap_mode'.
1446 (start_job_command): Fix format string for printing the result of
1447 process_easy.
1448 (start_job_command) [WINDOWS32]: Do not define.
1449 (exec_command): Fix format string for printing HANDLE args.
1451 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1452 to avoid compiler warnings.
1453 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1454 (Note: some of these fixes were submitted independently by J. Grant)
1456 2005-07-30 J. Grant <jg@jguk.org>
1458 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1459 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1460 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1462 2005-07-15 Paul Smith <psmith@gnu.org>
1464 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1465 we don't have a POSIX shell, then revert to the old
1466 backslash-newline behavior (where they are stripped).
1467 Fixes bug #13665.
1469 2005-07-08 Paul D. Smith <psmith@gnu.org>
1471 * config.h.W32.template: Reorder to match the standard config.h,
1472 for easier comparisons.
1473 From J. Grant <jg@jguk.org>
1475 * maintMakefile: Remove .dep_segment before overwriting it, in
1476 case it's not writable or noclobber is set.
1477 * expand.c (variable_expand_string): Cast result of pointer
1478 arithmetic to avoid a warning.
1479 * main.c (switches): Add full-fledged final initializer.
1481 2005-07-06 Paul D. Smith <psmith@gnu.org>
1483 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1484 * signame.c (strsignal): If we found _sys_siglist[] or
1485 __sys_siglist[] use those instead of sys_siglist[].
1486 From Albert Chin <china@thewrittenword.com>
1488 2005-07-04 Paul D. Smith <psmith@gnu.org>
1490 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1491 globfree(); set up to use the GNU versions.
1492 From Martin Zinser <zinser@zinser.no-ip.info>
1494 2005-07-03 Paul D. Smith <psmith@gnu.org>
1496 From J. Grant <jg@jguk.org>:
1498 * README.W32.template: Update the Windows and tested MSVC versions.
1499 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1500 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1501 * build_w32.bat: Ditto.
1502 * w32/subproc/build.bat: Ditto.
1504 2005-06-28 Paul D. Smith <psmith@gnu.org>
1506 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1507 declaration was checked but not present.
1509 2005-06-27 Paul D. Smith <psmith@gnu.org>
1511 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1512 to unsigned long. Fixes Savannah bug #13550.
1514 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1515 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1516 Fixes Savannah bug #13551.
1518 2005-06-26 Paul D. Smith <psmith@gnu.org>
1520 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1521 it if ANSI_STRING is not set.
1523 2005-06-25 Paul D. Smith <psmith@gnu.org>
1525 * read.c (eval): If no filenames are passed to any of the
1526 "include" variants, don't print an error.
1527 * doc/make.texi (Include): Document this.
1528 Fixes Savannah bug #1761.
1530 * job.c (construct_command_argv_internal): Sanitize handling of
1531 backslash/newline pairs according to POSIX: that is, keep the
1532 backslash-newline in the command script, but remove a following
1533 TAB character, if present. In the fast path, make sure that the
1534 behavior matches what the shell would do both inside and outside
1535 of quotes. In the slow path, quote the backslash and put a
1536 literal newline in the string.
1537 Fixes Savannah bug #1332.
1538 * doc/make.texi (Execution): Document the new behavior and give
1539 some examples.
1540 * NEWS: Make a note of the new behavior.
1542 * make.h [WINDOWS32]: #include <direct.h>.
1543 Fixes Savannah bug #13478.
1545 * remake.c (name_mtime): If the stat() of a file fails and the -L
1546 option was given and the file is a symlink, take the best mtime of
1547 the symlink we can get as the mtime of the file and don't fail.
1548 Fixes Savannah bug #13280.
1550 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1551 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1552 inside a variable reference. Make this function static as it's
1553 only used here.
1554 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1555 parsing an unexpanded line looking for semicolons.
1556 Fixes Savannah bug #1454.
1557 * misc.c (remove_comments): Move this to read.c and make it static
1558 as it's only used there. Call find_char_unquote() with new arg.
1559 * make.h: Remove prototypes for find_char_unquote() and
1560 remove_comments() since they're static now.
1562 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1563 its export flag and obtain its value. When we need to re-exec,
1564 increment the value and add it into the environment.
1565 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1566 * NEWS: Mention MAKE_RESTARTS.
1567 * main.c (always_make_set): New variable. Change the -B option to
1568 set this one instead.
1569 (main): When checking makefiles, only set always_make_flag if
1570 always_make_set is set AND the restarts flag is 0. When building
1571 normal targets, set it IFF always_make_set is set.
1572 (main): Avoid infinite recursion with -W, too: only set what-if
1573 files to NEW before we check makefiles if we've never restarted
1574 before. If we have restarted, set what-if files to NEW _after_ we
1575 check makefiles.
1576 Fixes Savannah bug #7566:
1578 2005-06-17 Paul D. Smith <psmith@gnu.org>
1580 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1581 in the prerequisites list.
1583 2005-06-12 Paul D. Smith <psmith@gnu.org>
1585 Fix Savannah bug # 1328.
1587 * configure.in: Check for atexit().
1588 * misc.c (close_stdout): Test stdout to see if writes to it have
1589 failed. If so, be sure to exit with a non-0 error code. Based on
1590 code found in gnulib.
1591 * make.h: Prototype.
1592 * main.c (main): Install close_stdout() with atexit().
1594 2005-06-10 Paul D. Smith <psmith@gnu.org>
1596 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1598 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1599 headers; make vmsWaitForChildren() static; extern vmsify().
1600 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1601 Don't create child_execute_job() here (it's in vmsjobs.c).
1602 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1604 2005-06-09 Paul D. Smith <psmith@gnu.org>
1606 * variable.c (push_new_variable_scope): File variables point
1607 directly to the global_setlist variable. So, inserting a new
1608 scope in front of that has no effect on those variables: they
1609 don't go through current_variable_set_list. If we're pushing a
1610 scope and the current scope is global, push it "the other way" so
1611 that the new setlist is in the global_setlist variable, and
1612 next points to a new setlist with the global variable set.
1613 (pop_variable_scope): Properly undo a push with the new
1614 semantics.
1615 Fixes Savannah bug #11913.
1617 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1619 * job.c (reap_children): Don't die of the command failed but
1620 the dontcare flag is set. Fixes Savannah bug #13216.
1622 * implicit.c (pattern_search): When creating a target from
1623 an implicit rule match, lookup pattern target and set precious
1624 flag in a newly created target. Fixes Savannah bug #13218.
1626 2005-05-13 Paul D. Smith <psmith@gnu.org>
1628 Implement "if... else if... endif" syntax.
1630 * read.c (eval): Push all checks for conditional words ("ifeq",
1631 "else", etc.) down into the conditional_line() function.
1632 (conditional_line): Rework to allow "else if..." clause. New
1633 return value -2 for lines which are not conditionals. The
1634 ignoring flag can now also be 2, which means "already parsed a
1635 true branch". If that value is seen no other branch of this
1636 conditional can be considered true. In the else parsing if there
1637 is extra text after the else, invoke conditional_line()
1638 recursively to see if it's another conditional. If not, it's an
1639 error. If so, raise the conditional value to this level instead
1640 of creating a new conditional nesting level. Special check for
1641 "else" and "endif", which aren't allowed on the "else" line.
1642 * doc/make.texi (Conditional Syntax): Document the new syntax.
1644 2005-05-09 Paul D. Smith <psmith@gnu.org>
1646 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1647 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1648 recurses to the w32 directory, even on non-Windows systems. Use
1649 the method suggested in the automake manual.
1650 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1651 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1653 2005-05-07 Paul D. Smith <psmith@gnu.org>
1655 * main.c (die): If we're dying with a fatal error (not that a
1656 command has failed), write back any leftover tokens before we go.
1658 * job.c (set_child_handler_action_flags): If there are jobs
1659 waiting for the load to go down, set an alarm to go off in 1
1660 second. This allows us to wake up from a potentially long-lasting
1661 read() and start a new job if the load has gone down. Turn it off
1662 after the read.
1663 (job_noop): Dummy signal handler function.
1664 (new_job): Invoke it with the new semantics.
1666 * docs/make.texi: Document secondary expansion. Various cleanups
1667 and random work.
1669 2005-05-03 Paul D. Smith <psmith@gnu.org>
1671 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1672 the targets which are to ultimately be made are called "goals";
1673 see the GNU make manual. Also, MAKECMDGOALS, etc.
1675 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1676 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1677 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1679 2005-05-02 Paul D. Smith <psmith@gnu.org>
1681 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1682 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1683 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1684 functions to vmsjobs.c. #include it into jobs.c.
1686 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1687 jobserver tokens. I found that this happens when an exported
1688 recursive variable contains a $(shell ...) function reference: in
1689 this situation we could "forget" to write back a token.
1691 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1692 we have. It's not reliable to depend on the number of children in
1693 our linked list so keep a separate count.
1694 (new_job): Check jobserver_tokens rather than children &&
1695 waiting_jobs. Increment jobserver_tokens when we get one.
1696 (free_child): If jobserver_tokens is 0, internal error. If it's
1697 >1, write a token back to the jobserver pipe (we don't write a
1698 token for the "free" job). Decrement jobserver_tokens.
1700 * main.c: Add variable master_job_slots.
1701 (main): Set it to hold the number of jobs requested if we're the
1702 master process, when using the jobserver.
1703 (die): Sanity checks: first test jobserver_tokens to make sure
1704 this process isn't holding any tokens we didn't write back.
1705 Second, if master_job_slots is set count the tokens left in the
1706 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1708 2005-04-24 Paul D. Smith <psmith@gnu.org>
1710 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1711 with -l# can lose jobserver tokens, because waiting jobs are not
1712 consulted properly when checking for the "free" token.
1714 * job.c (free_child): Count waiting_jobs as having tokens.
1715 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1716 handle jobs waiting for the load to drop.
1718 2005-04-23 Paul D. Smith <psmith@gnu.org>
1720 * main.c (main): Be careful to not core if a variable setting in
1721 the environment doesn't contain an '='. This is illegal but can
1722 happen in broken setups.
1723 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1725 2005-04-12 Paul D. Smith <psmith@gnu.org>
1727 The second expansion feature causes significant slowdown. Timing
1728 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1729 read the makefile before the feature, to 11+s to do the same
1730 operations after the feature. Additionally, memory usage
1731 increased drastically. To fix this I added some intelligence that
1732 avoids the overhead of the second expansion unless it's required.
1734 * dep.h: Add a new boolean field, need_2nd_expansion.
1736 * read.c (eval): When creating the struct dep for the target,
1737 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1738 (record_files): If there's a "%" in a static pattern rule, it gets
1739 converted to "$*" so set need_2nd_expansion to 1.
1741 * file.c (expand_deps): Rework to be more efficient. Only perform
1742 initialize_file_variables(), set_file_variables(), and
1743 variable_expand_for_file() if the need_2nd_expansion is set.
1745 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1746 (pattern_search): Ditto.
1747 * main.c (handle_non_switch_argument): Ditto.
1748 (main): Ditto.
1749 * read.c (read_all_makefiles): Ditto.
1750 (eval_makefile): Ditto.
1752 2005-04-07 Paul D. Smith <psmith@gnu.org>
1754 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1755 * variable.c (sync_Path_environment): Ditto.
1756 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1758 * main.c (main): Define the .FEATURES variable.
1759 * NEWS: Announce .FEATURES.
1760 * doc/make.texi (Special Variables): Document .FEATURES.
1762 * remake.c (check_dep): If a file is .PHONY, update it even if
1763 it's marked intermediate. Fixes Savannah bug #12331.
1765 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1767 * file.c (expand_deps): Factor out the second expansion and
1768 prerequisite line parsing logic from snap_deps().
1770 * file.c (snap_deps): Use expand_deps(). Expand and parse
1771 prerequisites of the .SUFFIXES special target first. Fixes
1772 Savannah bug #12320.
1774 2005-03-13 Paul D. Smith <psmith@gnu.org>
1776 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1777 Zaretskii.
1779 2005-03-11 Paul D. Smith <psmith@gnu.org>
1781 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1782 available, not undefined (from Earnie Boyd).
1784 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1786 * implicit.c (pattern_search): Mark an intermediate target as
1787 precious if it happened to be a prerequisite of some (other)
1788 target. Fixes Savannah bug #12267.
1790 2005-03-09 Paul D. Smith <psmith@gnu.org>
1792 * read.c (eval_makefile): Add alloca(0).
1793 (eval_buffer): Ditto.
1795 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1797 * main.c (main): Use o_file instead of o_default when defining
1798 the .DEFAULT_TARGET special variable.
1799 * read.c (eval): Use define_variable_global() instead of
1800 define_variable() when setting new value for the .DEFAULT_TARGET
1801 special variable. Fixes Savannah bug #12266.
1803 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1805 * imlicit.c (pattern_search): Mark files for which an implicit
1806 rule has been found as targets. Fixes Savannah bug #12202.
1808 2005-03-04 Paul D. Smith <psmith@gnu.org>
1810 * AUTHORS: Update.
1811 * doc/make.texi (Automatic Variables): Document $|.
1813 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1815 * read.c (record_files): Instead of substituting % with
1816 actual stem value in dependency list replace it with $*.
1817 This fixes stem triple expansion bug.
1819 * implicit.c (pattern_search): Copy stem to a separate
1820 buffer and make it a properly terminated string. Assign
1821 this buffer instead of STEM (which is not terminated) to
1822 f->stem. Instead of substituting % with actual stem value
1823 in dependency list replace it with $*. This fixes stem
1824 triple expansion bug.
1826 2005-03-01 Paul D. Smith <psmith@gnu.org>
1828 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1829 on Windows, as it takes a handle not a pid. Just exit.
1830 Fix from patch #3679, provided by Alessandro Vesely.
1832 * configure.in: Update check for sys_siglist[] from autoconf manual.
1833 * signame.c (strsignal): Update to use the new autoconf macro.
1835 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1837 * read.c (record_files): Add a check for the list of prerequisites
1838 of a static pattern rule being empty. Fixes Savannah bug #12180.
1840 2005-02-28 Paul D. Smith <psmith@gnu.org>
1842 * doc/make.texi (Text Functions): Update docs to allow the end
1843 ordinal for $(wordlist ...) to be 0.
1844 * function.c (func_wordlist): Fail if the start ordinal for
1845 $(wordlist ...) is <1. Matches documentation.
1846 Resolves Savannah support request #103195.
1848 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1849 previously we were stopping when !-q, exactly the opposite. This
1850 has been wrong since version 1.34, in 1994!
1851 (update_file): If we got an error don't break out to run more
1852 double-colon rules: just return immediately.
1853 Fixes Savannah bug #7144.
1855 2005-02-27 Paul D. Smith <psmith@gnu.org>
1857 * misc.c (end_of_token): Make argument const.
1858 * make.h: Update prototype.
1860 * function.c (abspath, func_realpath, func_abspath): Use
1861 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1862 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1863 * read.c (record_files): Ditto.
1864 * variable.c (do_variable_definition): Ditto.
1866 * function.c (func_error): Create a new function $(info ...) that
1867 simply prints the message to stdout with no extras.
1868 (function_table_init): Add new function to the table.
1869 * NEWS: Add $(info ...) reference.
1870 * doc/make.texi (Make Control Functions): Document it.
1872 New feature: if the system supports symbolic links, and the user
1873 provides the -L/--check-symlink-time flag, then use the latest
1874 mtime between the symlink(s) and the target file.
1876 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1877 readlink(). If both are available, define MAKE_SYMLINKS.
1878 * main.c: New variable: check_symlink_flag.
1879 (usage): Add a line for -L/--check-symlink-times to the help string.
1880 (switches): Add -L/--check-symlink-times command line argument.
1881 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1882 print a warning and disable it again.
1883 * make.h: Declare check_symlink_flag.
1884 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1885 if the file is a symlink then check each link in the chain and
1886 choose the NEWEST mtime we find as the mtime for the file. The
1887 newest mtime might be the file itself!
1888 * NEWS: Add information about this new feature.
1889 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1891 Avoid core dumps described in Savannah bug # 12124:
1893 * file.c: New variable snapped_deps remember whether we've run
1894 snap_deps().
1895 (snap_deps): Set it.
1896 * filedef.h: Extern it.
1897 * read.c (record_files): Check snapped_deps; if it's set then
1898 we're trying to eval a new target/prerequisite relationship from
1899 within a command script, which we don't support. Fatal.
1901 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1903 Implementation of the .DEFAULT_TARGET special variable.
1905 * read.c (eval): If necessary, update default_target_name when
1906 reading rules.
1907 * read.c (record_files): Update default_target_file if
1908 default_target_name has changed.
1909 * main.c (default_target_name): Define.
1910 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1911 default_target_name is set use default_target_file as a root
1912 target to make.
1913 * filedef.h (default_target_name): Declare.
1914 * dep.h (free_dep_chain):
1915 * misc.c (free_dep_chain): Change to operate on struct nameseq
1916 and change name to free_ns_chain.
1917 * file.c (snap_deps): Update to use free_ns_chain.
1919 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1921 Implementation of the second expansion in explicit rules,
1922 static pattern rules and implicit rules.
1924 * read.c (eval): Refrain from chopping up rule's dependencies.
1925 Store them in a struct dep as a single dependency line. Remove
1926 the code that implements SySV-style automatic variables.
1928 * read.c (record_files): Adjust the code that handles static
1929 pattern rules to expand all percents instead of only the first
1930 one. Reverse the order in which dependencies are stored so that
1931 when the second expansion reverses them again they appear in
1932 the makefile order (with some exceptions, see comments in
1933 the code). Remove the code that implements SySV-style automatic
1934 variables.
1936 * file.c (snap_deps): Implement the second expansion and chopping
1937 of dependency lines for explicit rules.
1939 * implicit.c (struct idep): Define an auxiliary data type to hold
1940 implicit rule's dependencies after stem substitution and
1941 expansion.
1943 * implicit.c (free_idep_chain): Implement.
1945 * implicit.c (get_next_word): Implement helper function for
1946 parsing implicit rule's dependency lines into words taking
1947 into account variable expansion requests. Used in the stem
1948 splitting code.
1950 * implicit.c (pattern_search): Implement the second expansion
1951 for implicit rules. Also fixes bug #12091.
1953 * commands.h (set_file_variables): Declare.
1954 * commands.c (set_file_variables): Remove static specifier.
1956 * dep.h (free_dep_chain): Declare.
1957 * misc.c (free_dep_chain): Implement.
1959 * variable.h (variable_expand_for_file): Declare.
1960 * expand.c (variable_expand_for_file): Remove static specifier.
1962 * make.h (strip_whitespace): Declare.
1963 * function.c (strip_whitespace): Remove static specifier.
1965 2005-02-26 Paul D. Smith <psmith@gnu.org>
1967 * main.c (main): Check for ferror() when reading makefiles from stdin.
1968 Apparently some shells in Windows don't close pipes properly and
1969 require this check.
1971 2005-02-24 Jonathan Grant <jg@jguk.org>
1973 * configure.in: Add MinGW configuration options, and extra w32 code
1974 directory.
1975 * Makefile.am: Add MinGW configuration options, and extra w32 code
1976 directory.
1977 * main.c: Determine correct program string (after last \ without .exe).
1978 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1979 type fix x2
1980 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1981 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1982 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1983 environment support.
1985 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1987 * function.c (func_shell): When initializing error_prefix, check
1988 that reading file name is not null. This fixes long-standing
1989 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1991 2005-02-09 Paul D. Smith <psmith@gnu.org>
1993 * maintMakefile: Update the CVS download URL to simplify them.
1994 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1995 downloading the .texi files from Savannah now.
1997 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1999 * main.c (handle_non_switch_argument): Only add variables to
2000 command_variables if they're not already there: duplicate settings
2001 waste space and can be confusing to read.
2003 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2004 this header is never included by non-WINDOWS32 code, and it
2005 requires <config.h> to define which isn't always included first.
2007 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2008 testing MINGW32 versions.
2010 * main.c (log_working_directory): flush stdout to be sure the WD
2011 change is printed before any stderr messages show up.
2013 2005-02-01 Paul D. Smith <psmith@gnu.org>
2015 * maintMakefile (po_repo): Update the GNU translation site URL.
2017 2004-12-01 Paul D. Smith <psmith@gnu.org>
2019 * main.c (main): Change char* env_shell to struct variable shell_var.
2020 * variable.c (target_environment): Use new shell_var.
2022 2004-11-30 Paul D. Smith <psmith@gnu.org>
2024 * configure.in: The old way we avoided creating build.sh from
2025 build.sh.in before build.sh.in exists doesn't work anymore; we
2026 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2027 the help!). This also keeps automake from complaining.
2028 * Makefile.am (README): Add a dummy target so automake won't
2029 complain that this file doesn't exist when we checkout from CVS.
2030 * maintMakefile (.dep_segment): Rewrite this rule since newer
2031 versions of automake don't provide DEP_FILES.
2033 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2035 Implementation of `realpath' and `abspath' built-in functions.
2037 * configure.in: Check for realpath.
2038 * function.c (abspath): Return an absolute file name that does
2039 not contain any `.' or `..' components, nor repeated `/'.
2040 * function.c (func_abspath): For each name call abspath.
2041 * function.c (func_realpath): For each name call realpath
2042 from libc or delegate to abspath if realpath is not available.
2043 * doc/make.texi (Functions for File Names): Document new functions.
2044 * doc/make.texi (Quick Reference): Ditto.
2046 2004-11-28 Paul D. Smith <psmith@gnu.org>
2048 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2049 arguments. Fixes bug #10252.
2051 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2053 * main.c (main): Set SHELL to v_noexport by default. Remember the
2054 original environment setting of SHELL in the env_shell variable.
2055 * main.h: Export new env_shell variable.
2056 * variable.c (target_environment): If we find a v_noexport
2057 variable for SHELL, add a SHELL variable with the env_shell value.
2058 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2059 * doc/make.texi (Variables/Recursion): Ditto.
2061 2004-11-28 Paul D. Smith <psmith@gnu.org>
2063 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2064 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2065 Patch by Alessandro Vesely.
2067 2004-11-12 Paul D. Smith <psmith@gnu.org>
2069 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2070 the command line if it's inside a string.
2071 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2073 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2075 * function.c (func_lastword): New function: return last word
2076 from the list of words.
2077 * doc/make.texi: Document $(lastword ). Fix broken links in
2078 Quick Reference section.
2080 2004-10-06 Paul D. Smith <psmith@gnu.org>
2082 Apply patch from Alessandro Vesely, provided with bug # 9748.
2083 Fix use of tmpnam() to work with Borland C.
2085 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2086 construction of a temporary filename, and call new function
2087 create_batch_filename().
2088 (create_batch_filename) [WINDOWS32]: New function to create a
2089 temporary filename.
2091 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2093 * read.c (record_target_var): Expand simple pattern-specific
2094 variable.
2095 * variable.c (initialize_file_variables): Do not expand simple
2096 pattern-specific variable.
2098 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2100 * remake.c (update_file_1): When rebuilding makefiles inherit
2101 dontcare flag from a target that triggered update.
2103 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2105 * variable.c (initialize_file_variables): Mark pattern-specific
2106 variable as a per-target and copy export status.
2108 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2110 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2112 * implicit.c (pattern_search): When considering an implicit rule's
2113 prerequisite check that it is actually a target rather then
2114 just an entry in the file hashtable.
2116 2004-09-21 Paul D. Smith <psmith@gnu.org>
2118 * read.c (readstring): Fix some logic errors in backslash handling.
2119 (eval): Remove some unnecessary processing in buffer handling.
2120 (record_target_var): Assert that parse_variable_definition() succeeded.
2121 Reported by: Markus Mauhart <qwe123@chello.at>.
2123 * misc.c: Removed the sindex() function. All instances of this
2124 function were trivially replaceable by the standard strstr()
2125 function, and that function will always have better (or certainly
2126 no worse) performance than the very simple-minded algorithm
2127 sindex() used. This can matter with complex makefiles.
2128 * make.h: Remove the prototype for sindex().
2129 * function.c (subst_expand): Convert sindex() call to strstr().
2130 This means we no longer need to track the TLEN value so remove that.
2131 (func_findstring): Convert sindex() to strstr().
2132 * commands.c (chop_commands): Convert sindex() calls to strstr().
2133 Suggested by: Markus Mauhart <qwe123@chello.at>.
2135 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2136 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2137 If SHELL is set to CMD.EXE then assume it's batch-mode and
2138 non-unixy. I wrote the code differently from the patch, though,
2139 to make it safer. This also resolves bug #9174.
2141 2004-09-20 Paul D. Smith <psmith@gnu.org>
2143 * expand.c (variable_expand_string): Modify to invoke
2144 patsubst_expand() instead of subst_expand(); the latter didn't
2145 handle suffix patterns correctly.
2146 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2147 was used only from variable_expand_string() and is no longer used
2148 there.
2149 (func_subst): Ditto, on call to subst_expand().
2150 (patsubst_expand): Require the percent pointers to point to the
2151 character after the %, not to the % itself.
2152 * read.c (record_files): New call criteria for patsubst_expand().
2153 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2154 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2156 2004-09-19 Paul D. Smith <psmith@gnu.org>
2158 * function.c (subst_expand): Fix a check in by_word: look for a
2159 previous blank if we're beyond the beginning of the string, not
2160 the beginning of the word.
2161 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2163 2004-05-16 Paul D. Smith <psmith@gnu.org>
2165 * remake.c (update_goal_chain): Change the argument specifying
2166 whether we're rebuilding makefiles to be a global variable,
2167 REBUILDING_MAKEFILES.
2168 (complain): Extract the code that complains about no rules to make
2169 a target into a separate function.
2170 (update_file_1): If we tried to rebuild a file during the makefile
2171 rebuild phase and it was dontcare, then no message was printed.
2172 If we then try to build the same file during the normal build,
2173 print a message this time.
2174 (remake_file): Don't complain about un-remake-able files when
2175 we're rebuilding makefiles.
2177 2004-05-11 Paul D. Smith <psmith@gnu.org>
2179 * job.c (construct_command_argv_internal): OS/2 patches from
2180 Andreas Buening <andreas.buening@nexgo.de>.
2182 2004-05-10 Paul D. Smith <psmith@gnu.org>
2184 * remake.c (update_file): Don't walk the double-colon chain unless
2185 this is a double-colon rule. Fix suggested by Boris Kolpackov
2186 <boris@kolpackov.net>.
2188 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2189 * readme.vms: New section describing OpenVMS support and issues.
2190 * default.c (default_variables): Add support for IA64.
2191 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2192 without some privilege aborts make with the error
2193 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2194 pressing Ctrl+Y and the input device is no terminal. The change
2195 catches this error and just continues.
2197 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2199 2004-04-25 Paul D. Smith <psmith@gnu.org>
2201 * commands.c (set_file_variables): Set $< properly in the face of
2202 order-only prerequisites.
2203 Patch from Boris Kolpackov <boris@kolpackov.net>
2205 2004-04-21 Bob Byrnes <byrnes@curl.com>
2207 * main.c (main): Notice failures to remake makefiles.
2209 2004-03-28 Paul D. Smith <psmith@gnu.org>
2211 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2213 * job.c: No default shell for RISC OS.
2214 (load_too_high): Hard-code the return to 1.
2215 (construct_command_argv_internal): No sh_chars or sh_cmds.
2216 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2218 2004-03-20 Paul D. Smith <psmith@gnu.org>
2220 * variable.c (do_variable_definition): Don't append from the
2221 global set if a previous non-appending target-specific variable
2222 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2223 (with fix).
2225 * expand.c (reference_variable): Don't give up on variables with
2226 no value that have the target-specific append flag set: they might
2227 have a value after all. Reported by Oliver Schmidt
2228 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2229 <nikulin@dx1cmd.inp.nsk.su>.
2231 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2232 refer to absolute pathnames in directories that don't exist: some
2233 portion of the makefile could create those directories before we
2234 match the pattern. Fixes bugs #775 and #108.
2236 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2238 * main.c (main): Free makefile_mtimes if we have any.
2239 * README.W32.template: Update documentation for the current status
2240 of the MS-Windows port.
2241 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2242 environment variable is sometimes already defined which causes the
2243 build to fail.
2244 * main.c (debug_signal_handler): Only define this function if
2245 SIGUSR1 is available.
2247 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2249 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2250 * README.OS2.template: Documentation updates.
2251 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2252 link line for safety.
2253 * maintMakefile (build.sh.in): Remove an extraneous ")".
2254 * job.c (child_execute_job): Close saved FDs.
2255 * job.c (exec_command) [OS/2]: exec_command(): If the command
2256 can't be exec'ed and if the shell is not Unix-sh, then try again
2257 with argv = { "cmd", "/c", ... }. Normally, this code is never
2258 reached for the cmd shell unless the command really doesn't exist.
2259 (construct_command_argv_internal) [OS/2]: The code for cmd
2260 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2261 The CMD builtin commands are case insensitive so use strcasecmp().
2263 2004-03-19 Paul D. Smith <psmith@gnu.org>
2265 * read.c (do_define): Re-order line counter increment so the count
2266 is accurate (we were losing one line per define). Reported by
2267 Dave Yost <Dave@Yost.com>.
2269 2004-03-06 Paul D. Smith <psmith@gnu.org>
2271 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2272 compiler.
2273 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2274 * misc.c (message,error,fatal): Ditto.
2275 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2276 * config.h.W32.template: Ditto.
2277 * config.h-vms.template: Ditto.
2278 * config.ami.template: Ditto.
2280 2004-03-04 Paul D. Smith <psmith@gnu.org>
2282 * README.template: Add a note about broken /bin/sh on SunOS
2283 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2285 * misc.c (message, error, fatal): Don't use "..." if we're using
2286 varargs. ansi2knr should handle this but it doesn't work: it
2287 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2288 done. On many systems (SunOS for example) va_dcl is a #define.
2289 So, force the use of the non-"..." version on pre-ANSI compilers.
2291 * maintMakefile (sign-dist): Create some rules to help automate
2292 the new GNU ftp upload method.
2294 2004-02-24 Paul D. Smith <psmith@gnu.org>
2296 * config.h.W32.template: Add HAVE_STDARG_H
2297 * config.h-vms.template: Ditto.
2298 * config.ami.template: Ditto.
2300 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2302 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2303 * build_w32.bat: Remove extra "+".
2305 2004-02-23 Paul D. Smith <psmith@gnu.org>
2307 * make.h: Create an UNUSED macro to mark unused parameters.
2308 * (many): Clean up warnings by applying UNUSED, fixing
2309 signed/unsigned incompatibilities, etc.
2311 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2312 autoconf warnings.
2313 * filedef.h: Name the command_state enumeration.
2314 * file.c (set_command_state): Use the enumeration in the function
2315 argument.
2317 * configure.in: Explicitly set SET_MAKE to empty, to disable
2318 MAKE=make even when no make already exists. Fix bug #3823.
2320 2004-02-22 Paul D. Smith <psmith@gnu.org>
2322 * maintMakefile: Perl script to clean up all non-CVS files. Use
2323 it on all the subdirectories for the cvs-clean target.
2325 * main.c (decode_switches): Require non-empty strings for all our
2326 string command-line options. Fixes Debian bug # 164165.
2328 * configure.in: Check for stdarg.h and varargs.h.
2329 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2330 for printing messages.
2331 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2332 (message): Ditto.
2333 (error): Ditto.
2334 (fatal): Ditto.
2336 A number of patches for OS/2 support from Andreas Buening
2337 <andreas.buening@nexgo.de>:
2339 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2340 disable the SIGCHLD handler.
2341 (reap_children) [OS/2]: Remove special handling of job_rfd.
2342 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2343 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2344 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2345 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2346 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2347 systems.
2349 2004-02-21 Paul D. Smith <psmith@gnu.org>
2351 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2352 <mail@kristov.de> reports that if process_begin() fails we don't
2353 handle the error condition correctly in all cases.
2354 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2355 to have a newline on the message.
2357 * job.c (construct_command_argv_internal): Add "test" to UNIX
2358 sh_cmds[]. Fixes Savannah bug # 7606.
2360 2004-02-04 Paul D. Smith <psmith@gnu.org>
2362 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2363 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2364 Hartmut Becker <Hartmut.Becker@hp.com>.
2366 2004-01-21 Paul D. Smith <psmith@gnu.org>
2368 * job.c (load_too_high): Implement an algorithm to control the
2369 "thundering herd" problem when using -l to control job creation
2370 via the load average. The system only recomputes the load once a
2371 second but we can start many jobs in a second. To solve this we
2372 keep track of the number of jobs started in the last second and
2373 apply a weight to try to guess what a correct load would be.
2374 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2375 Also fixes bug #4693.
2376 (reap_children): Decrease the job count for this second.
2377 (start_job_command): Increase the job count for this second.
2379 * read.c (conditional_line): Expand the text after ifn?def before
2380 checking to see if it's a single word. Fixes bug #7257.
2382 2004-01-09 Paul D. Smith <psmith@gnu.org>
2384 * file.c (print_file): Recurse to print all targets in
2385 double-colon rules. Fixes bug #4518, reported (with patch) by
2386 Andrew Chatham <chatham@google.com>.
2388 2004-01-07 Paul D. Smith <psmith@gnu.org>
2390 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2391 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2392 AC_FUNC_SETVBUF_REVERSED.
2394 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2395 (MAKE Variable): Fix Savannah bug #4898.
2397 * job.c (construct_command_argv_internal): Add "!" to the list of
2398 shell escape chars. POSIX sh allows it to appear before a
2399 command, to negate the exit code. Fixes bug #6404.
2401 * implicit.c (pattern_search): When matching an implicit rule,
2402 remember which dependencies have the ignore_mtime flag set.
2403 Original fix provided in Savannah patch #2349, by Benoit
2404 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2406 2003-11-22 Paul D. Smith <psmith@gnu.org>
2408 * README.W32.template (Outputs): Clarification on -j with
2409 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2410 <jg-make@jguk.org>.
2412 2003-11-02 Paul D. Smith <psmith@gnu.org>
2414 * function.c (func_if): Strip all the trailing whitespace from the
2415 condition, then don't expand it. Fixed bug # 5798.
2417 * expand.c (recursively_expand_for_file): If we're expanding a
2418 variable with no file context, then use the variable's context.
2419 Fixes bug # 6195.
2421 2003-10-21 Paul D. Smith <psmith@gnu.org>
2423 * main.c (log_working_directory): Add newlines to printf()s.
2425 * README.cvs: Add a note to ignore warnings during autoreconf.
2427 * maintMakefile (po_repo): Set a new URL for PO file updates.
2428 (get-config/config.guess get-config/config.sub): Get these files
2429 from the Savannah config project instead of ftp.gnu.org.
2431 2003-10-05 Paul Eggert <eggert@twinsun.com>
2433 * main.c (main): Avoid potential subscript error if environ has
2434 short strings.
2436 2003-08-22 Paul D. Smith <psmith@gnu.org>
2438 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2439 systems which don't yet implement the C89 standard :-/.
2441 2003-07-18 Paul D. Smith <psmith@gnu.org>
2443 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2444 [WINDOWS32]: Initialize hash.
2446 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2448 * dir.c (read_dirstream): Provide a workaround for broken versions of
2449 the MinGW dirent structure.
2451 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2453 * w32/include/dirent.h: Add __MINGW32__ filter.
2455 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2457 * make.h: Add global declaration of *make_host.
2458 * main.c (print_usage): Remove local declaration of *make_host.
2459 (print_version): Display "This program built for ..." after Copyright
2460 notice.
2462 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2464 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2465 execution of "makeinfo --html make.texi".
2467 2003-04-30 Paul D. Smith <psmith@gnu.org>
2469 * build.template: Make some changes to maybe allow this script to
2470 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2472 * README.OS2.template: New file for OS/2 support. Original
2473 contributed by Andreas Buening.
2474 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2475 DOS-style paths.
2477 2003-04-19 Paul D. Smith <psmith@gnu.org>
2479 Fix bug #1405: allow a target to match multiple pattern-specific
2480 variables.
2482 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2483 variable.c, where they've always belonged.
2484 * rule.h: Move the prototypes and struct pattern_var as well.
2485 * variable.c (initialize_file_variables): Invoke
2486 lookup_pattern_var() in a loop, until no more matches are found.
2487 If a match is found, create a new variable set for the target's
2488 pattern variables. Then merge the contents of each matching
2489 pattern variable set into the target's pattern variable set.
2490 (lookup_pattern_var): Change this function to be usable
2491 in a loop. It takes a starting position: if NULL, start at the
2492 beginning; if non-NULL, start with the pattern variable after that
2493 position, and return the next matching pattern.
2494 (create_pattern_var): Create a unique instance of
2495 pattern-specific variables for every definition in the makefile.
2496 Don't combine the same pattern together. This allows us to
2497 process the variable handling properly even when the same pattern
2498 is used multiple times.
2499 (parse_variable_definition): New function: break out the parsing
2500 of a variable definition line from try_variable_definition.
2501 (try_variable_definition): Call parse_variable_definition to
2502 parse.
2503 (print_variable_data_base): Print out pattern-specific variables.
2504 * variable.h (struct variable): Remember when a variable is
2505 conditional. Also remember its flavor.
2506 (struct pattern_var): Instead of keeping a variable set, we just
2507 keep a single variable for each pattern.
2508 * read.c (record_target_var): Each pattern variable contains only a
2509 single variable, not a set, so create it properly.
2510 * doc/make.texi (Pattern-specific): Document the new behavior.
2512 2003-04-17 Paul D. Smith <psmith@gnu.org>
2514 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2515 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2516 file/directory naming rules for VMS so I can't tell whether this
2517 is correct or not.
2519 2003-04-09 Paul D. Smith <psmith@gnu.org>
2521 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2522 DOS-style pathnames: backslash separators and drive specifiers.
2524 2003-03-28 Paul D. Smith <psmith@gnu.org>
2526 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2527 the intermediate flag on all targets. Fixes bug #2515.
2529 2003-03-24 Paul D. Smith <psmith@gnu.org>
2531 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2532 Upgrade to autoconf 2.57 and automake 1.7.3.
2534 * job.c: More OS/2 changes from Andreas Buening.
2536 * file.c (print_file): Fix variable initialization.
2537 Fixes bug #2892.
2539 * remake.c (notice_finished_file):
2541 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2542 some calls (like readdir()) return NULL in valid situations
2543 without resetting errno. Fixes bug #2846.
2545 2003-02-25 Paul D. Smith <psmith@gnu.org>
2547 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2549 * job.c (_is_unixy_shell) [OS/2]: New function.
2550 Set default shell to /bin/sh.
2551 (reap_children): Close the job_rfd pipe here since we don't use a
2552 SIGCHLD handler.
2553 (set_child_handler_action_flags): define this to empty on OS/2.
2554 (start_job_command): Close the jobserver pipe and use
2555 child_execute_job() instead of fork/exec.
2556 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2557 rather than exec'ing, then reconfigure stdin/stdout.
2558 (exec_command): Rewrite to use spawn instead of exec. Return the
2559 PID of the child.
2561 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2562 in DOS. Handle the TEMP environment variable as in DOS. Don't
2563 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2564 use -j in DOS mode. Use child_execute_job() instead of
2565 exec_command().
2567 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2568 spawn() instead.
2570 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2571 prototypes that return values.
2573 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2575 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2576 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2577 for OS/2.
2578 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2579 DOS paths.
2581 2003-02-24 Paul D. Smith <psmith@gnu.org>
2583 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2584 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2585 (child_execute_job) [VMS]: Handle error status properly.
2586 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2588 * function.c (func_shell): Use EINTRLOOP() while reading from the
2589 subshell pipe (Fixes bug #2502).
2590 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2591 jobserver pipe.
2592 * main.c (main): Ditto.
2594 2003-01-30 Paul D. Smith <psmith@gnu.org>
2596 * read.c (eval): eval() was not fully reentrant, because the
2597 collapsed buffer was static. Change it to be an automatic
2598 variable so that eval() can be invoked recursively.
2599 Fixes bug # 2238.
2600 (eval): Apply patch # 1022: fix memory reference error on long
2601 target-specific variable lines.
2602 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2604 * function.c (check_numeric): Combine the is_numeric() function
2605 into this function, since it's only called from one place.
2606 Constify this function. Have it print the incorrect string in the
2607 error message. Fixes bug #2407.
2608 (strip_whitespace): Constify.
2609 (func_if): Constify.
2610 * expand.c (expand_argument): Constify.
2612 2003-01-29 Paul D. Smith <psmith@gnu.org>
2614 Fix bug # 2169, also reported by other people on various systems.
2616 * make.h: Some systems, such as Solaris and PTX, do not fully
2617 implement POSIX-compliant SA_RESTART functionality; important
2618 system calls like stat() and readdir() can still fail with EINTR
2619 even if SA_RESTART has been set on the signal handler. So,
2620 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2621 EINTR for system calls which return -1 or 0 (NULL), respectively,
2622 on error.
2623 Also, remove the old atomic_stat()/atomic_readdir() and
2624 HAVE_BROKEN_RESTART handling.
2626 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2628 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2629 * remake.c (touch_file): Ditto.
2631 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2632 * read.c (construct_include_path): Ditto.
2633 * remake.c (name_mtime): Ditto.
2634 * vpath.c (selective_vpath_search): Ditto.
2635 * dir.c (find_directory): Ditto.
2636 (local_stat): Ditto.
2637 (find_directory): Use ENULLLOOP() to wrap opendir().
2638 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2640 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2641 atomic_readdir() handling.
2643 2003-01-22 Paul D. Smith <psmith@gnu.org>
2645 * function.c (func_call): Fix Bug #1744. If we're inside a
2646 recursive invocation of $(call ...), mask any of the outer
2647 invocation's arguments that aren't used by this one, so that this
2648 invocation doesn't "inherit" them accidentally.
2650 2002-12-05 Paul D. Smith <psmith@gnu.org>
2652 * function.c (subst_expand): Valery Khamenia reported a
2653 pathological performance hit when doing substitutions on very
2654 large values with lots of words: turns out we were invoking
2655 strlen() a ridiculous number of times. Instead of having each
2656 call to sindex() call strlen() again, keep track of how much of
2657 the text we've seen and pass the length to sindex().
2659 2002-11-19 Paul D. Smith <psmith@gnu.org>
2661 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2664 2002-11-16 Paul D. Smith <psmith@gnu.org>
2666 * NMakefile.template (OBJS): Add hash.c object file.
2667 * SMakefile.template (srcs): Ditto.
2668 * Makefile.ami (objs): Ditto.
2669 * build_w32.bat: Ditto.
2671 * Makefile.DOS.template: Remove extra dependencies.
2673 2002-10-25 Paul D. Smith <psmith@gnu.org>
2675 * expand.c (install_variable_buffer): New function. Install a new
2676 variable_buffer context and return the previous one.
2677 (restore_variable_buffer): New function. Free the current
2678 variable_buffer context and put a previously saved one back.
2679 * variable.h: Prototypes for {install,restore}_variable_buffer.
2680 * function.c (func_eval): Push a new variable_buffer context
2681 before we eval, then restore the old one when we're done.
2682 Fixes Bug #1517.
2684 * read.c (install_conditionals): New function. Install a new
2685 conditional context and return the previous one.
2686 (restore_conditionals): New function. Free the current
2687 conditional context and put a previously saved one back.
2688 (eval): Use the {install,restore}_conditionals for "include"
2689 handling.
2690 (eval_buffer): Use {install,restore}_conditionals to preserve the
2691 present conditional state before we evaluate the buffer.
2692 Fixes Bug #1516.
2694 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2695 and $(value ...).
2696 (Recursion): Add a variable index entry for CURDIR.
2698 * README.cvs: Update to appropriate versions.
2699 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2700 don't need to copy loadavg.c: automake is smart enough to create
2701 it for me. Still have a bug in automake related to ansi2knr tho.
2703 2002-10-14 Paul D. Smith <psmith@gnu.org>
2705 * remake.c (notice_finished_file): Only touch targets if they have
2706 at least one command (as per POSIX). Resolve Bug #1418.
2708 * *.c: Convert to using ANSI C-style function definitions.
2709 * Makefile.am: Enable the ansi2knr feature of automake.
2710 * configure.in: ditto.
2712 2002-10-13 Paul D. Smith <psmith@gnu.org>
2714 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2715 for automatic variable values like $^, etc. In the case of very
2716 large lists of prerequisites this causes problems. Instead reuse
2717 a static buffer (resizeable) for each variable.
2719 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2720 target-specific variable definitions. Check for it and set an
2721 "exported" flag.
2722 (record_target_var): Set the export field to v_export if the
2723 "exported" flag is set.
2724 * doc/make.texi (Target-specific): Document the ability to use
2725 "export".
2727 * doc/make.texi: Change the name of the section on automatic
2728 variables from "Automatic" to "Automatic Variables". Added text
2729 clarifying the scope of automatic variables.
2731 2002-10-04 Paul D. Smith <psmith@gnu.org>
2733 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2734 as () braces.
2735 (record_files): Ditto.
2737 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2738 the search for the '=' to only within the enclosing parens.
2740 2002-10-03 Paul D. Smith <psmith@gnu.org>
2742 Version 3.80 released.
2744 * dir.c: Change hash functions to use K&R function definition style.
2745 * function.c: Ditto.
2746 * read.c: Ditto.
2747 * variable.c: Ditto.
2749 Update to automake 1.7.
2751 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2752 (pdf): Remove this target as automake now provides one.
2754 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2756 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2758 * makefile.com: Updates for GNU make 3.80.
2759 * makefile.vms: Ditto.
2761 2002-09-23 Paul D. Smith <psmith@gnu.org>
2763 * read.c (enum make_word_type): Remove w_comment.
2764 (get_next_mword): Don't treat comment characters as special; where
2765 this function is used we will never see a comment (it's stripped
2766 before we get here) and treating comments specially means that
2767 targets like "foo\#bar" aren't handled properly.
2769 2002-09-18 Paul D. Smith <psmith@gnu.org>
2771 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2773 * read.c (eval): Expansion of arguments to export/unexport was
2774 ignoring all arguments after the first one. Change the algorithm
2775 to expand the whole line once, then parse the results.
2777 2002-09-17 Paul D. Smith <psmith@gnu.org>
2779 Fix Bug #940 (plus another bug I found while looking at this):
2781 * read.c (record_target_var): enter_file() will add a new entry if
2782 it's a double-colon target: we don't want to do that in this
2783 situation. Invoke lookup_file() and only enter_file() if it does
2784 not already exist. If the file we get back is a double-colon then
2785 add this variable to the "root" double-colon target.
2787 * variable.c (initialize_file_variables): If this file is a
2788 double-colon target but is not the "root" target, then initialize
2789 the root and make the root's variable list the parent of our
2790 variable list.
2792 2002-09-13 Paul D. Smith <psmith@gnu.org>
2794 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2796 * hash.c (round_up_2): Get rid of a warning.
2798 2002-09-12 Paul D. Smith <psmith@gnu.org>
2800 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2801 so it doesn't complain about getloadavg.c.
2803 * commands.c (set_file_variables): Make sure we always alloca() at
2804 least 1 character for the value of $? (for '\0').
2806 2002-09-11 Paul D. Smith <psmith@gnu.org>
2808 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2809 macro to use RESULT instead of the incorrect _RESULT_.
2811 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2812 and atomic_readdir(). We need to #include dirent.h to get this to
2813 work.
2814 * misc.c (atomic_readdir): Fix typos.
2816 2002-09-10 Paul D. Smith <psmith@gnu.org>
2818 * read.c (eval): Expand variable lists given to export and
2819 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2820 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2822 * doc/make.texi (Variables/Recursion): Document this.
2823 (Conditional Syntax): And here.
2825 2002-09-09 Paul D. Smith <psmith@gnu.org>
2827 * configure.in: Check for memmove().
2829 2002-09-07 Paul D. Smith <psmith@gnu.org>
2831 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2832 Michael Sterrett <msterret@coat.com> reports that while it has
2833 SA_RESTART, it does not work properly.
2835 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2836 that invokes stat() and loops to do it again if it returns EINTR.
2837 (atomic_readdir): Ditto, with readdir().
2839 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2840 and readdir() to atomic_stat() and atomic_readdir().
2842 2002-09-04 Paul D. Smith <psmith@gnu.org>
2844 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2845 reports that GNU make sometimes doesn't recognize that targets can
2846 be made, when directories can be created as prerequisites. He
2847 reports that changing the order of predicates in the DEP->changed
2848 flag test so that lookup_file() is always performed, solves this
2849 problem.
2851 2002-08-08 Paul D. Smith <psmith@gnu.org>
2853 * configure.in: Require a newer version of gettext.
2855 * misc.c (perror_with_name): Translate the format string (for
2856 right-to-left language support).
2857 (pfatal_with_name): Ditto.
2859 * main.c: Create a static array of strings to store the usage
2860 text. This is done to facilitate translations.
2861 (struct command_switch): Remove argdesc and description fields.
2862 (switches): Remove values for obsolete fields.
2863 (print_usage): Print each element of the usage array.
2865 * hash.c: Change function definitions to be K&R style.
2867 2002-08-02 Paul D. Smith <psmith@gnu.org>
2869 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2870 this one because it's too hard to get right. We'll look at it for
2871 a future release.
2872 * main.c (main): Don't create the .TARGETS variable.
2873 * variable.c (handle_special_var): Don't handle .TARGETS.
2875 2002-08-01 Paul D. Smith <psmith@gnu.org>
2877 * main.c (switches): Add a new option, -B (--always-make). If
2878 specified, make will rebuild all targets that it encounters even
2879 if they don't appear to be out of date.
2880 (always_make_flag): New flag.
2881 * make.h: Extern always_make_flag.
2882 * remake.c (update_file_1): Check always_make_flag; if it's set we
2883 will always rebuild any target we can, even if none of its
2884 prerequisites are newer.
2885 * NEWS: Mention it.
2887 * doc/make.texi (Shell Function): Make it clear that make
2888 variables marked as "export" are not passed to instances of the
2889 shell function.
2891 Add new introspection variable .VARIABLES and .TARGETS.
2893 * variable.c (handle_special_var): New function. If the variable
2894 reference passed in is "special" (.VARIABLES or .TARGETS),
2895 calculate the new value if necessary. .VARIABLES is handled here:
2896 walk through the hash of defined variables and construct a value
2897 which is a list of the names. .TARGETS is handled by
2898 build_target_list().
2899 (lookup_variable): Invoke handle_special_var().
2900 * file.c (build_target_list): Walk through the hask of known files
2901 and construct a list of the names of all the ones marked as
2902 targets.
2903 * main.c (main): Initialize them to empty (and as simple variables).
2904 * doc/make.texi (Special Variables): Document them.
2905 * NEWS: Mention them.
2907 * variable.h (struct variable): Add a new flag "exportable" which
2908 is true if the variable name is valid for export.
2909 * variable.c (define_variable_in_set): Set "exportable" when a new
2910 variable is defined.
2911 (target_environment): Use the "exportable" flag instead of
2912 re-checking the name here... an efficiency improvement.
2914 2002-07-31 Paul D. Smith <psmith@gnu.org>
2916 * config.h-vms.template: Updates to build on VMS. Thanks to
2917 Brian_Benning@aksteel.com for helping verify the build.
2918 * makefile.com: Build the new hash.c file.
2919 * hash.h: Use strcpmi(), not stricmp(), in the
2920 HAVE_CASE_INSENSITIVE_FS case.
2922 2002-07-30 Paul D. Smith <psmith@gnu.org>
2924 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2925 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2926 Reported by <Brian_Benning@aksteel.com>.
2928 2002-07-10 Paul D. Smith <psmith@gnu.org>
2930 * variable.c (pop_variable_scope): Remove variable made unused by
2931 new hash infrastructure.
2932 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2933 comparisons as well as name comparisons.
2934 * variable.h: Add a prototype for new hash_init_function_table().
2935 * file.c (lookup_file): Remove variables made unused by new hash
2936 infrastructure.
2937 * dir.c (directory_contents_hash_2): Missing return of hash value.
2938 (dir_contents_file_exists_p): Remove variables made unused by new
2939 hash infrastructure.
2942 Installed Greg McGary's integration of the hash functions from the
2943 GNU id-utils package:
2945 2002-07-10 Greg McGary <greg@mcgary.org>
2947 * scripts/functions/filter-out: Add literals to to the
2948 pattern space in order to add complexity, and trigger
2949 use of an internal hash table. Fix documentation strings.
2950 * scripts/targets/INTERMEDIATE: Reverse order of files
2951 passed to expected `rm' command.
2953 2002-07-10 Greg McGary <greg@mcgary.org>

3025 (find_char_unquote): Accept two char-constant stop chars, rather
3026 than a string constant, avoiding zillions of calls to strchr.
3027 Tighten inner search loops to test only for desired delimiters.
3029 * variable.c (variable_hash_1, variable_hash_2,
3030 variable_hash_cmp): New functions.
3031 (variable_table): Declare as `struct hash_table'.
3032 (global_variable_set): Remove initialization.
3033 (init_hash_global_variable_set): New function.
3034 (define_variable_in_set): Use new hash table package.
3035 (lookup_variable): Likewise.
3036 (lookup_variable_in_set): Likewise.
3037 (initialize_file_variables): Likewise.
3038 (pop_variable_scope): Likewise.
3039 (create_new_variable_set): Likewise.
3040 (merge_variable_sets): Likewise.
3041 (define_automatic_variables): Likewise.
3042 (target_environment): Likewise.
3043 (print_variable_set): Likewise.
3045 2002-07-10 Paul D. Smith <psmith@gnu.org>
3047 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3048 prerequisite list. A real SysV make will expand the entire
3049 prerequisites list _twice_: we don't do that as it's a big
3050 backward-compatibility problem. We only replace those specific
3051 variables.
3053 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3054 references left in the list of prerequisites. Check for .POSIX as
3055 we record targets, so we can disable non-POSIX behavior while
3056 reading makefiles as well as running them.
3057 (eval): Check the prerequisite list to see if we have anything
3058 that looks like a SysV prerequisite variable reference.
3060 2002-07-09 Paul D. Smith <psmith@gnu.org>
3062 * doc/make.texi (Prerequisite Types): Add a new section describing
3063 order-only prerequisites.
3065 * read.c (uniquize_deps): If we have the same file as both a
3066 normal and order-only prereq, get rid of the order-only prereq,
3067 since the normal one supersedes it.
3069 2002-07-08 Paul D. Smith <psmith@gnu.org>
3071 * AUTHORS: Added Greg McGary to the AUTHORS file.
3072 * NEWS: Blurbed order-only prerequisites.
3073 * file.c (print_file): Show order-only deps properly when printing
3074 the database.
3076 * maintMakefile: Add "update" targets for wget'ing the latest
3077 versions of various external files. Taken from Makefile.maint in
3078 autoconf, etc.
3080 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3081 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3083 2002-07-07 Paul D. Smith <psmith@gnu.org>
3085 * po/*.po: Remove. We'll use wget to retrieve them at release
3086 time.
3088 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3089 rather than a shell you get an exception. Make sure we look up
3090 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3092 * remake.c (notice_finished_file): Fix handling of -t flag.
3093 Patch provided by Henning Makholm <henning@makholm.net>.
3095 * implicit.c (pattern_search): Some systems apparently run short
3096 of stack space, and using alloca() in this function caused an
3097 overrun. I modified it to use xmalloc() on the two variables
3098 which seemed like they might get large. Fixes Bug #476.
3100 * main.c (print_version): Update copyright notice to conform with
3101 GNU standards.
3102 (print_usage): Update help output.
3104 * function.c (func_eval): Create a new make function, $(eval
3105 ...). Expand the arguments, put them into a buffer, then invoke
3106 eval_buffer() on the resulting string.
3107 (func_quote): Create a new function, $(quote VARNAME). Inserts
3108 the value of the variable VARNAME without expanding it any
3109 further.
3111 * read.c (struct ebuffer): Change the linebuffer structure to an
3112 "eval buffer", which can be either a file or a buffer.
3113 (eval_makefile): Move the code in the old read_makefile() which
3114 located a makefile into here: create a struct ebuffer with that
3115 information. Have it invoke the new function eval() with that
3116 ebuffer.
3117 (eval_buffer): Create a new function that creates a struct ebuffer
3118 that holds a string buffer instead of a file. Have it invoke
3119 eval() with that ebuffer.
3120 (eval): New function that contains the guts of the old
3121 read_makefile() function: this function parses makefiles. Obtains
3122 data to parse from the provided ebuffer. Some modifications to
3123 make the flow of the function cleaner and clearer. Still could
3124 use some work here...
3125 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3126 contents of the define/endef variable from the ebuffer.
3127 (readstring): Read the next line from a string-style ebuffer.
3128 (readline): Read the next line from an ebuffer. If it's a string
3129 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3130 from the file.
3132 * dep.h (eval_buffer): Prototype eval_buffer();
3134 * variable.c (do_variable_definition): Make sure that all
3135 non-target-specific variables are registered in the global set.
3136 If we're invoked from an $(eval ...) we might be inside a $(call
3137 ...) or other function which has pushed a variable scope; we still
3138 want to define our variables from evaluated makefile code in the
3139 global scope.
3141 2002-07-03 Greg McGary <greg@mcgary.org>
3143 * dep.h (struct dep) [ignore_mtime]: New member.
3144 [changed]: convert to a bitfield.
3145 * implicit.c (pattern_search): Zero ignore_mtime.
3146 * main.c (main, handle_non_switch_argument): Likewise.
3147 * rule.c (convert_suffix_rule): Likewise.
3148 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3149 (read_makefile): Parse '|' in prerequisite list.
3150 (uniquize_deps): Consider ignore_mtime when comparing deps.
3151 * remake.c (update_file_1, check_dep): Don't force remake for
3152 dependencies that have d->ignore_mtime.
3153 * commands.c (FILE_LIST_SEPARATOR): New constant.
3154 (set_file_variables): Don't include a
3155 prerequisite in $+, $^ or $? if d->ignore_mtime.
3156 Define $|.
3158 2002-06-18 Paul D. Smith <psmith@gnu.org>
3160 * make.texinfo: Updates for next revision. New date/rev/etc.
3161 Recreate all Info menus. Change license on the manual to the GNU
3162 Free Documentation License. A number of typos.
3163 (Variables Simplify): Don't use "-" before it's defined.
3164 (Automatic Prerequisites): Rewrite the target example to work
3165 properly if the compile fails. Remove incorrect comments about
3166 how "set -e" behaves.
3167 (Text Functions): Move the "word", "wordlist", "words", and
3168 "firstword" functions here, from "File Name Functions".
3169 * make-stds.texi: Update from latest GNU version.
3170 * fdl.texi: (created) Import the latest GNU version.
3172 2002-06-06 Paul D. Smith <psmith@gnu.org>
3174 * variable.c (do_variable_definition): New function: extract the
3175 part of try_variable_definition() that actually sets the value
3176 into a separate function.
3177 (try_variable_definition): Call do_variable_definition() after
3178 parsing the variable definition string.
3179 (define_variable_in_set): Make the name argument const.
3181 * variable.h (enum variable_flavor): Make public.
3182 (do_variable_definition): Create prototype.
3184 * read.c (read_all_makefiles): Create a new built-in variable,
3185 MAKEFILE_LIST.
3186 (read_makefile): Add each makefile read in to this variable value.
3188 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3190 * Makefile.DOS.template: Tweak according to changes in the
3191 distribution. Add back the dependencies of *.o files.
3193 * configh.dos.template: Synchronize with config.h.in.
3195 2002-05-09 Paul D. Smith <psmith@gnu.org>
3197 * file.c (file_timestamp_now): Use K&R function declaration.
3199 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3200 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3201 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3202 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3203 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3204 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3205 nlist.n_name is a pointer rather than an array.
3207 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3208 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3209 * configure.in: Use it instead of the old version.
3211 * main.c (main): Prefer setvbuf() to setlinebuf().
3213 2002-05-08 Paul D. Smith <psmith@gnu.org>
3215 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3216 (loadavg_LDADD): Ditto.
3218 2002-04-29 Paul D. Smith <psmith@gnu.org>
3220 * expand.c (recursively_expand_for_file): Rename
3221 recursively_expand() to recursively_expand_for_file() and provide
3222 an extra argument, struct file. If the argument is provided, set
3223 the variable scope to that of the file before expanding.
3224 * variable.h (recursively_expand): Make this a macro that invokes
3225 recursively_expand_for_file() with a NULL file pointer.
3226 * variable.c (target_environment): Call the renamed function and
3227 provide the current file context.
3228 Fixes Debian bug #144306.
3230 2002-04-28 Paul D. Smith <psmith@gnu.org>
3232 Allow $(call ...) user-defined variables to be self-referencing
3233 without throwing an error. Allows implementation of transitive
3234 closures, among other possibly useful things.
3235 Requested by: Philip Guenther <guenther@sendmail.com>
3237 * variable.h (struct variable): Add a new field: exp_count, and
3238 new macros to hold its size and maximum value.
3239 (warn_undefined): Make this a macro.
3240 * variable.c (define_variable_in_set): Initialize it.
3241 * expand.c (recursively_expand): If we detect recursive expansion
3242 of a variable, check the exp_count field. If it's greater than 0
3243 allow the recursion and decrement the count.
3244 (warn_undefined): Remove this (now a macro in variable.h).
3245 * function.c (func_call): Before we expand the user-defined
3246 function, modify its exp_count field to contain the maximum
3247 number of recursive calls we'll allow. After the call, reset it
3248 to 0.
3250 2002-04-21 Paul D. Smith <psmith@gnu.org>
3252 Modified to use latest autoconf (2.53), automake (1.6.1), and
3253 gettext (0.11.1). We're using gettext's new "external" support,
3254 to avoid including libintl source with GNU make.
3256 * README.cvs: New file. Explain how to build GNU make from CVS.
3258 * configure.in: Modify checking for the system glob library.
3259 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3260 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3261 etc. will manage it correctly). Set an automake conditional
3262 USE_LOCAL_GLOB to decide whether to compile the glob library.
3264 * getloadavg.c (main): Include make.h in the "TEST" program to
3265 avoid warnings.
3267 * Makefile.am: Remove special rules for loadavg. Replace them
3268 with Automake capabilities for building extra programs.
3270 * signame.c: This file does nothing if the system provide
3271 strsignal(). If not, it implements strsignal(). If the system
3272 doesn't define sys_siglist, then we make our own; otherwise we use
3273 the system version.
3274 * signame.h: Removed.
3276 * main.c (main): No need to invoke signame_init(). Update copyright.
3278 * ABOUT-NLS: Removed.
3279 * gettext.c: Removed.
3280 * gettext.h: Get a simplified copy from the gettext package.
3281 * po/*: Created.
3282 * i18n/*.po: Moved to po/.
3283 * i18n/: Removed.
3285 * config/*: Created. Contains package configuration helper files.
3286 * config.guess, config.sub: Moved to config directory.
3288 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3289 Rework to use new-style autoconf features. Use the "external"
3290 mode for gettext. Make the build.sh config file conditional on
3291 whether build.sh.in exists, to avoid autoconf errors.
3292 * acinclude.m4: Removed almost all macros as being obsolete.
3293 Rewrote remaining macros to use AC_DEFINE.
3294 * acconfig.h: Removed.
3296 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3297 conditional to handle customs support. Remove special handling
3298 for i18n features.
3300 2002-04-20 Paul D. Smith <psmith@gnu.org>
3302 * function.c (func_call): Don't mark the argument variables $1,
3303 etc. as recursive. They've already been fully expanded so
3304 there's no need to do it again, and doing so strips escaped $'s.
3305 Reported by Sebastian Glita <glseba@yahoo.com>.
3307 * remake.c (notice_finished_file): Walk through double-colon
3308 entries via the prev field, not the next field!
3309 Reported by Greg McGary <greg@mcgary.org>.
3311 * main.c (main): If the user specifies -q and asks for a specific
3312 target which is a makefile, we got an assert. In that case it
3313 turns out we should continue normally instead.
3315 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3317 * i18n/he.po: Installed a new translation.
3319 2002-01-07 Paul D. Smith <psmith@gnu.org>
3321 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3323 2001-12-04 Paul D. Smith <psmith@gnu.org>
3325 * i18n/ja.po: Installed an updated translation.
3327 2001-09-06 Paul Eggert <eggert@twinsun.com>
3329 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3330 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3332 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3333 are available.
3334 (main): Get rid of any avoidable limit on stack size.
3336 2001-09-04 Paul D. Smith <psmith@gnu.org>
3338 * i18n/da.po: Installed an updated translation.
3340 2001-08-03 Paul D. Smith <psmith@gnu.org>
3342 * i18n/fr.po: Installed an updated translation.
3343 Resolves Debian bug #106720.
3345 2001-06-13 Paul D. Smith <psmith@gnu.org>
3347 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3348 translation.
3350 2001-06-11 Paul D. Smith <psmith@gnu.org>
3352 * i18n/ko.po: Installed a new translation.
3354 2001-05-06 Paul D. Smith <psmith@gnu.org>
3356 Modify the EINTR handling.
3358 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3359 the way in which we manage the file descriptor/signal handler race
3360 trap to be more efficient.
3362 2001-05-06 Paul Eggert <eggert@twinsun.com>
3364 Restart almost all system calls that are interrupted, instead
3365 of worrying about EINTR. The lone exception is the read() for
3366 job tokens.
3368 * configure.in (HAVE_SA_RESTART): New macro.
3369 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3370 * main.c (main): Use SA_RESTART instead of the old,
3371 nonstandard SA_INTERRUPT.
3373 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3374 * main.c (bsd_signal): New function or macro,
3375 if the implementation doesn't supply it.
3376 (The bsd_signal function will be in POSIX 1003.1-200x.)
3377 (HANDLESIG): Remove.
3378 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3380 * make.h (EINTR_SET): Remove.
3381 (SA_RESTART): New macro.
3383 * arscan.c (ar_member_touch): Don't worry about EINTR.
3384 * function.c (func_shell): Likewise.
3385 * job.c (reap_children, free_child, new_job): Likewise.
3386 * main.c (main): Likewise.
3387 * remake.c (touch_file, name_mtime): Likewise.
3389 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3390 if fstat failed with errno!=EINTR, the error was ignored.
3392 * job.c (set_child_handler_action_flags): New function.
3393 (new_job): Use it to temporarily clear the SIGCHLD action flags
3394 while reading the token.
3396 2001-05-02 Paul D. Smith <psmith@gnu.org>
3398 * job.c (start_job_command): Don't add define/endef per-line flags
3399 to the top-level flags setting.
3401 2001-04-03 Paul D. Smith <psmith@gnu.org>
3403 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3404 bit on error, so check for odd return values, not non-0 return
3405 values.
3406 (VMS_get_member_info): Calculate the timezone differences correctly.
3407 Reported by John Fowler <jfowler@nyx.net>.
3410 2001-03-14 Paul D. Smith <psmith@gnu.org>
3412 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3413 value before invoking define_variable().
3414 Reported by John Fowler <jfowler@nyx.net>.
3416 2001-02-07 Paul D. Smith <psmith@gnu.org>
3418 * read.c (record_target_var): If we reset the variable due to a
3419 command-line variable setting overriding it, turn off the "append"
3420 flag.
3422 2001-01-17 Paul D. Smith <psmith@gnu.org>
3424 * variable.c (lookup_variable) [VMS]: When getting values from the
3425 environment, allocate enough space for the _value_ plus escapes,
3426 not enough space for the name plus escapes :-/.
3427 Reported by John Fowler <jfowler@nyx.net>.
3429 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3430 warnings that make generates, so it doesn't look like an error.
3431 Reported by Karl Berry <karl@gnu.org>.
3434 Fix for PR/2020: Rework appended target-specific variables. I'm
3435 fairly confident this algorithm is finally correct.
3437 * expand.c (allocated_variable_append): Rewrite. Instead of
3438 expanding each appended variable then adding all the expanded
3439 strings together, we append all the unexpanded values going up
3440 through the variable set contexts, then expand the final result.
3441 This behaves just like non-target-specific appended variable
3442 values, while the old way didn't in various corner cases.
3443 (variable_append): New function: recursively append the unexpanded
3444 value of a variable, walking from the outermost variable scope to
3445 the innermost.
3446 * variable.c (lookup_variable): Remove the code that looked up the
3447 variable set list if the found variable was "append". We don't
3448 need this anymore.
3449 (lookup_variable_in_set): Make this non-static so we can use it
3450 elsewhere.
3451 (try_variable_definition): Use lookup_variable_in_set() rather
3452 than faking out current_variable_set_list by hand (cleanup).
3453 * variable.h: Add a prototype for the now non-static
3454 lookup_variable_in_set().
3456 2000-11-17 Paul D. Smith <psmith@gnu.org>
3458 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3459 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3460 before throwing a fit.
3462 2000-11-17 Paul D. Smith <psmith@gnu.org>
3464 * read.c (readline): CRLF calculations had a hole, if you hit the
3465 buffer grow scenario just right. Reworked the algorithm to avoid
3466 the need for len or lastlen at all. Problem description with
3467 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3469 2000-10-24 Paul D. Smith <psmith@gnu.org>
3471 * gettext.c (SWAP): Declare this with the prototype, otherwise
3472 some systems don't work (non-32-bit? Reported for Cray T3E).
3473 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3475 2000-10-05 Paul D. Smith <psmith@gnu.org>
3477 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3478 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3480 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3482 2000-09-22 Paul D. Smith <psmith@gnu.org>
3484 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3485 parts of the real gettext.h here, and we expect to really include
3486 the real gettext.h later. If we keep this #define, it's ignored.
3488 2000-09-21 Paul D. Smith <psmith@gnu.org>
3490 * main.c (log_working_directory): Rework the text to use complete
3491 sentences, to make life simpler for the translators.
3493 2000-08-29 Paul D. Smith <psmith@gnu.org>
3495 * file.c (remove_intermediates): Print a debug message before we
3496 remove intermediate files, so the user (if she uses -d) knows
3497 what's going on.
3499 2000-08-21 Paul D. Smith <psmith@gnu.org>
3501 * variable.c (try_variable_definition): Change how we handle
3502 target-specific append variable defns: instead of just setting the
3503 value, expand it as an append _but_ only within the current
3504 target's context. Otherwise we lose all but the last value if the
3505 variable is appended more than once within the current target
3506 context. Fixes PR/1831.
3508 2000-08-16 Paul D. Smith <psmith@gnu.org>
3510 * function.c (func_shell): Nul-terminate the buffer before
3511 printing an exec error message (just in case it's not!).
3512 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3514 2000-07-25 Paul D. Smith <psmith@gnu.org>
3516 * job.c (construct_command_argv_internal): Add "~" to the list of
3517 sh_chars[] which disallow optimizing out the shell call.
3519 2000-07-23 Paul Eggert <eggert@twinsun.com>
3521 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3522 supersedes --disable-nsec-timestamps.
3523 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3524 * README: Remove --disable-nsec-timestamps.
3526 * filedef.h (struct file.low_resolution_time): New member.
3527 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3528 * remake.c (update_file_1):
3529 Avoid spurious rebuilds due to low resolution time stamps,
3530 generalizing the earlier code that applied only to archive members.
3531 (f_mtime): Archive members always have low resolution time stamps.
3533 * configure.in: Remove --disable-nsec-timestamps, as this has
3534 been superseded by .LOW_RESOLUTION_TIME.
3536 2000-07-23 Paul Eggert <eggert@twinsun.com>
3538 * configure.in (enable_nsec_timestamps): Renamed from
3539 make_cv_nsec_timestamps, since enable/disable options
3540 shouldn't be cached.
3542 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3543 and Paul Eggert <eggert@twinsun.com>
3545 * file.c (file_timestamp_now):
3546 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3547 so that clock_gettime is not linked unless needed.
3549 * filedef.h (FILE_TIMESTAMP_HI_RES):
3550 Remove definition; "configure" now does this.
3552 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3553 to before high resolution file timestamp check,
3554 since that check now uses uintmax_t.
3555 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3556 high resolution file timestamps.
3557 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3558 so that we don't link in clock_gettime unnecessarily.
3560 2000-07-17 Paul D. Smith <psmith@gnu.org>
3562 * i18n/ja.po: New version of the translation file.
3564 2000-07-07 Paul D. Smith <psmith@gnu.org>
3566 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3567 the offset calculation.
3568 (name_mtime): Replace EINTR test with EINTR_SET macro.
3570 2000-07-07 Paul Eggert <eggert@twinsun.com>
3572 Fix for PR/1811:
3574 * remake.c (update_file_1):
3575 Avoid spurious rebuilds of archive members due to their
3576 timestamp resolution being only one second.
3577 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3578 the clock's resolution being lower than file timestamps'.
3579 When warning about future timestamps, report only the discrepancy,
3580 not the absolute value of the timestamp and the current time.
3582 * file.c (file_timestamp_now): New arg RESOLUTION.
3583 * filedef.h (file_timestamp_now): Likewise.
3584 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3586 2000-07-05 Paul D. Smith <psmith@gnu.org>
3588 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3589 to listp. Fixes PR/1793.
3591 2000-06-26 Paul Eggert <eggert@twinsun.com>
3593 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3595 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3597 * remake.c (f_mtime): Remove unused var memtime.
3599 2000-06-25 Martin Buchholz <martin@xemacs.org>
3601 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3602 Ran spell-check on make.texinfo.
3604 2000-06-23 Paul D. Smith <psmith@gnu.org>
3606 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3607 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3608 * make.h: Define these macros.
3610 * Version 3.79.1 released.
3612 * configure.in: Add a new option, --disable-nsec-timestamps, to
3613 avoid using sub-second timestamps on systems that support it. It
3614 can lead to problems, e.g. if your makefile relies on "cp -p".
3615 * README.template: Document the issue with "cp -p".
3617 * config.guess, config.sub: Updated.
