1 2009-10-03 Paul Smith <psmith@gnu.org>
3 * make.h: Include <alloca.h> even on systems where __GNUC__ is
4 defined. Not sure why it was done the other way.
5 Requested by David Boyce <dsb@boyski.com>.
7 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
9 * dep.h (dep): Add the DONTCARE bitfield.
11 * filedef.h (file):Add the NO_DIAG bitfield.
13 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
14 not struct file (a file can be a dependency of many targets,
15 some don't care, some do).
17 * remake.c (update_goal_chain): Propagate DONTCARE from struct
18 dep to struct file before updating the goal and restore it
20 (update_file): Don't prune the dependency graph if this target
21 has failed but the diagnostics hasn't been issued.
22 (complain): Scan the file's dependency graph to find the file
23 that caused the failure.
24 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
25 whether to print diagnostics.
27 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
29 2009-09-28 Paul Smith <psmith@gnu.org>
31 * doc/make.texi (Pattern Intro): Move the match algorithm
32 discussion into the "Pattern Match" node.
33 (Pattern Match): Expand on the pattern rule matching algorithm.
35 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
37 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
38 much of the command line on a single pass.
40 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
42 * varible.c (create_pattern_var): Insert variables into the
43 PATTERN_VARS list in the shortest patterns first order.
45 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
46 used to sort the rules.
47 (stemlen_compare): Compare two tryrule elements.
48 (pattern_search): Sort the rules so that they are in the shortest
51 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
53 * doc/make.texi (Pattern-specific Variable Values): Describe the
54 new pattern-specific variables application order.
55 (Introduction to Pattern Rules): Describe the new pattern rules
58 * NEWS: Add a note about the new behavior.
60 2009-09-27 Paul Smith <psmith@gnu.org>
62 * doc/make.texi (Double-Colon): Mention that pattern rules with
63 double-colons have a different meaning. Savannah bug #27497.
65 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
67 * configh.dos.template: Remove unconditional definition of
69 Include <sys/version.h> because ports of GCC 4.3.0 and later no
70 longer include it, so macros like __DJGPP_MINOR__ are no longer
71 defined automatically.
73 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
74 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
75 instead of using the hardcoded ones.
76 (SUBDIRS): doc subdir added.
77 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
78 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
79 create html formated docs. texi2html may not be ported to DOS.
80 (make.info, make.dvi, make.ps, make.html): Make targets depend on
82 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
83 -I switch to look in ./ instead of ./doc.
84 (html): Target depend on html-recursive instead of make_1.html.
85 (make_1.html): Removed.
86 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
87 (all-recursive): Allow for more than one subdir in the build
89 (mostlyclean-recursive, clean-recursive, distclean-recursive)
90 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
91 (tags-recursive): Allow for more than one subdir in the build
93 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
94 targets. Enter into doc/ to produce the targets.
95 (all-am): $(INFO_DEPS) replaced by info.
97 2009-09-26 Paul Smith <psmith@gnu.org>
99 * read.c (record_files): Use free_ns() to free struct nameseq.
102 * rule.c (freerule): Use free_dep_chain().
104 * read.c (record_files): Free FILENAMES chain for implicit rules.
105 (eval): Static pattern targets go into the string cache.
107 * function.c (string_glob): Free NAME in the nameseq chain.
109 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
111 * implicit.c (pattern_search): Terminate early if we haven't
112 found any rules to try (performance improvement).
114 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
116 * implicit.c (pattern_search): Merge three parallel arrays,
117 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
118 of struct TRYRULE. In the old version the latter two arrays
119 had insufficient length.
121 2009-09-24 Paul Smith <psmith@gnu.org>
123 * implicit.c (pattern_search): Add back support for order-only
124 prerequisites for secondary expansion implicit rules, that were
125 accidentally dropped. If we find a "|", enable order-only mode
126 and set IGNORE_MTIME on all deps that are seen afterward.
127 (pattern_search): Fix memory leaks: for intermediate files where
128 we've already set the file variable and pattern variable sets, be
129 sure to either save or free them as appropriate.
131 2009-09-23 Paul Smith <psmith@gnu.org>
133 Rework the way secondary expansion is stored, for efficiency.
134 This changes secondary expansion so that ONLY WHEN we know we have
135 a possibility of needing secondary expansion, do we defer the
136 secondary expansion. This means more parsing the deps but we use
137 a lot less memory (due to the strcache). Also, this fixes
140 * read.c (eval): Don't parse the dep string here anymore.
141 (record_files): Take the dep argument as an unparsed string. If
142 secondary expansion is enabled AND the prereq string has a '$' in
143 it, then set NEED_2ND_EXPANSION and keep the entire string.
144 Otherwise, parse the dep string here to construct the dep list
145 with the names in the strcache.
147 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
148 duplicate the name string (others are in the strcache).
150 * implicit.c: Remove struct idep and free_idep_chain(): unused.
151 (struct patdeps): New structure to store prereq information.
152 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
153 which prerequisites need expansion, and expand only those.
155 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
156 and enter_prereqs(). split_prereqs() takes a fully-expanded string
157 and splits it into a DEP list, handling order-only prereqs.
158 (enter_prereqs): This function enters a list of DEPs into the file
159 database. If there's a stem defined, expand any pattern chars.
160 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
161 set. Use the above functions.
162 (snap_deps): Only perform second expansion on prereqs that need it,
163 as defined by the NEED_2ND_EXPANSION flag.
164 (print_prereqs): New function to print the prereqs
165 (print_file): Call print_prereqs() rather than print inline.
167 * hash.h (STRING_COMPARE): Take advantage of strcache() by
169 (STRING_N_COMPARE): Ditto.
170 (ISTRING_COMPARE): Ditto.
172 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
173 (parse_file_seq): Return void*
174 * read.c (parse_file_seq): Return void*.
175 (eval): Invoke macroized version of parse_file_seq()
176 * default.c (set_default_suffixes): Ditto.
177 * file.c (split_prereqs): Ditto.
178 * function.c (string_glob): Ditto.
179 * main.c (main): Ditto.
180 * rule.c (install_pattern_rule): Ditto.
182 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
184 2009-09-16 Paul Smith <psmith@gnu.org>
186 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
188 * dep.h: Create alloc_dep() / free_dep() macros.
190 * implicit.c (pattern_search): Take advantage of the new
191 parse_file_seq() to add the directory prefix to each prereq.
193 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
194 all. Avoid reversing chains. Support adding prefixes.
195 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
196 cached/non-cached results.
197 (eval): Remove multi_glob() & invoke new parse_file_seq().
198 * rule.c (install_pattern_rule): Ditto.
199 * main.c (main): Ditto.
200 * implicit.c (pattern_search): Ditto.
201 * function.c (string_glob): Ditto.
202 * file.c (parse_prereqs): Ditto.
203 * default.c (set_default_suffixes): Ditto.
205 * variable.c (parse_variable_definition): Don't run off the end of
206 the string if it ends in whitespace (found with valgrind).
208 * commands.c (set_file_variables): Keep space for all targets in
209 $? if -B is given (found with valgrind).
211 2009-09-15 Paul Smith <psmith@gnu.org>
213 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
214 (xcalloc): Add new function.
215 * make.h: New declarations.
217 * ar.c (ar_glob_match): New calling method for concat().
218 * main.c (main): Ditto.
219 (decode_env_switches): Ditto.
220 * read.c (eval_makefile): Ditto.
221 (tilde_expand): Ditto.
222 (parse_file_seq): Ditto.
223 * variable.c (target_environment): Ditto.
224 (sync_Path_environment): Ditto.
226 * ar.c (ar_glob_match): Use xcalloc().
227 * dir.c (file_impossible): Ditto.
228 * file.c (enter_file): Ditto.
229 * job.c (new_job): Ditto.
230 * read.c (parse_file_seq): Ditto.
231 * vmsfunctions.c (opendir): Ditto.
233 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
235 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
236 inside the loop that looks up environment for PATH.
238 2009-08-31 Eli Zaretskii <eliz@gnu.org>
240 * function.c (windows32_openpipe): Update envp after calling
241 sync_Path_environment.
243 2009-08-02 Paul Smith <psmith@gnu.org>
245 * remake.c (notice_finished_file): Ensure file->cmds is not null
246 before looping through them. Fixes Savannah bug #21824.
248 * doc/make.texi (Wildcard Examples): Clarify when objects is
249 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
250 (Include): Clarify the behavior of -include.
251 Fixes Savannah bug #18963.
253 2009-08-01 Paul Smith <psmith@gnu.org>
255 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
256 etc. come on the command line. Fixes Savannah bug #27093.
258 * expand.c (expand_argument): If the argument is large enough use
259 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
261 * variable.c (do_variable_definition): Avoid using alloca() to
262 hold values, which can be large. Fixes Savannah bug #23960.
264 * job.c (new_job): Use memmove() instead of strcpy() since both
265 pointers are in the same memory block. Fixes Savannah bug #27148.
266 Patch by Petr Machata.
268 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
270 * job.c (construct_command_argv_internal): Add "ulimit" and
271 "unset" to the sh_cmds for Unixy shells.
273 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
275 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
276 that set make_cv_sys_gnu_glob, so they are also correctly set
277 when the cache has been populated before.
279 2009-07-04 Eli Zaretskii <eliz@gnu.org>
281 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
282 exist, as realpath(3) does where it's supported.
284 2006-07-04 Eli Zaretskii <eliz@gnu.org>
286 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
287 (abspath): Support systems that define HAVE_DOS_PATHS (have
288 drive letters in their file names). Use IS_PATHSEP instead of a
289 literal '/' comparison. Fixes Savannah bug #26886.
291 2009-06-14 Paul Smith <psmith@gnu.org>
293 * remake.c (update_file_1): Remember the original file we marked
294 as updating, so we can clear that flag again. If we find a target
295 via vpath, FILE might change.
296 (check_dep): Ditto. Fixes Savannah bug #13529.
297 Patch by Reid Madsen <reid.madsen@tek.com>.
299 2009-06-13 Paul Smith <psmith@gnu.org>
301 * doc/make.texi (MAKEFILES Variable): Be explicit that files
302 included by MAKEFILES cannot give default goals.
303 * read.c (eval): If set_default is not set, pass the no-default-goal
304 value when we read included makefiles. Fixes Savannah bug #13401.
306 * ar.c (ar_name): Ensure that targets with empty parens aren't
307 considered archive member references: archive members must have a
308 non-empty "member" string. Fixes Savannah bug #18435.
310 * function.c (string_glob): Rely on multi_glob() to determine
311 whether files exist or not. Remove call to file_exists_p() which
312 is not always correct. Fixes Savannah bug #21231.
313 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
314 then only files that really exist will be returned.
315 * dep.h: Add new argument to multi_glob().
316 * rule.c (install_pattern_rule): Ditto.
317 * read.c (eval): Ditto.
318 * main.c (main): Ditto.
319 * implicit.c (pattern_search): Ditto.
320 * file.c (parse_prereqs): Ditto.
321 * default.c (set_default_suffixes): Ditto.
323 2009-06-09 Paul Smith <psmith@gnu.org>
325 * commands.c (set_file_variables): If always_make_flag is set,
326 always add the prereq to $?. Fixes Savannah bug #17825.
328 * remake.c (update_file_1): When rebuilding deps of FILE, also try
329 to rebuild the deps of all the also_make targets for that file.
330 Fixes Savannah bug #19108.
332 * implicit.c (pattern_search): Undo test for is_target, added by
333 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
334 Rule Search Algorithm". Fixes Savannah bug #17752.
336 * main.c (clean_jobserver): Clear the jobserver_fds options and
337 set job_slots to the default when we clean up.
338 (define_makeflags): Return the new MAKEFLAGS value.
339 (main): Reset MAKEFLAGS in the environment when we re-exec.
340 Fixes Savannah bug #18124.
342 2009-06-08 Paul Smith <psmith@gnu.org>
344 * read.c (eval): Collapse continuations post-semicolon on target-
345 specific variables. Fixes Savannah bug #17521.
347 2009-06-07 Paul Smith <psmith@gnu.org>
349 * job.c (reap_children): For older systems without waitpid() (are
350 there any of these left?) run wait(2) inside EINTRLOOP to handle
351 EINTR errors. Fixes Savannah bug #16401.
353 * (various): Debug message cleanup. Fixes Savannah bug #16469.
355 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
357 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
358 not the end, to catch second expansion $(eval ...) defining new
359 target/prereq relationships during snap_deps.
360 Fixes Savannah bug #24622.
362 * read.c (record_files): The second-expansion "f->updating" hack
363 was not completely correct: if assumed that the target with
364 commands always had prerequisites; if one didn't then the ordering
365 was messed up. Fixed for now to use f->updating to decide whether
366 to preserve the last element in the deps list... but this whole
367 area of constructing and reversing the deps list is too confusing
368 and needs to be reworked. Fixes Savannah bug #21198.
370 2009-06-06 Paul Smith <psmith@gnu.org>
372 * hash.c (hash_insert): Remove useless test for NULL.
373 Fixes Savannah bug #21823.
375 * make.h: Move SET_STACK_SIZE determination to make.h.
376 * main.c (main): New global variable, STACK_LIMIT, holds the
377 original stack limit when make was started.
378 * job.c (start_job_command): Reset the stack limit, if we changed it.
379 Fixes Savannah bug #22010.
381 * remake.c (check_dep): Only set the target's state to not-started
382 if it's not already running. Found this while testing -j10 builds
383 of glibc: various targets were being rebuilt multiple times.
384 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
387 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
388 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
391 2009-06-04 Paul Smith <psmith@gnu.org>
393 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
395 * maintMakefile: Modify access of config and gnulib Savannah
396 modules to use GIT instead of CVS.
398 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
399 Fixes Savannah bug #24655.
401 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
402 this can happen during some invocations of $(eval ...) for example.
403 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
405 2009-06-02 Paul Smith <psmith@gnu.org>
407 * configure.in: Check for fileno()
408 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
409 for the makefile file so invocations of $(shell ...) don't inherit it.
410 Fixes Savannah bug #24277.
412 2009-06-01 Paul Smith <psmith@gnu.org>
414 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
415 expansion was handled incorrectly. Rework the default goal
416 handling to save the variable only. Remove default_goal_file and
418 * read.c (eval): Check default_goal_var, not default_goal_name.
419 * read.c (record_target_var): Don't check default_goal_file here.
421 2009-05-31 Paul Smith <psmith@gnu.org>
423 * main.c (main): Expand the .DEFAULT_GOAL variable before using
424 it, and if the multi_glob() returns nothing (say it expanded to
425 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
427 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
428 $(and ..) to the reference. Fixes Savannah bug #25694.
430 * make.1: Be clear that some recipes will be executed even with -n.
431 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
433 * doc/make.texi (Override Directive): Make more clear how
434 overrides and appends interact.
435 Elucidates part of Savannah bug #26207.
437 * read.c (record_target_var): Don't reset the origin on
438 target-specific variables; try_variable_definition() will handle
439 this correctly. Fixes Savannah bug #26207.
441 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
442 Fixes Savannah bug #25712.
444 * implicit.c (pattern_search): Keep a pointer to the beginning of
445 the filename and save that instead of the constructed pointer.
446 Fixes Savannah bug #26593.
447 Patch by Mark Seaborn <mrs@mythic-beasts.com>
449 2009-05-30 Paul Smith <psmith@gnu.org>
451 * doc/make.texi (Multi-Line): Add a description of the new abilities
452 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
453 "command sequence" vs. "recipe" syntax.
454 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
455 after a define, to create variables with those flavors.
457 2009-05-25 Paul Smith <psmith@gnu.org>
459 Reworked the parser for variable assignments to allow multiple
460 modifiers, and in any order. Also allows variable and
461 prerequisites to be modifier names ('export', 'private', etc.)
463 * NEWS: Add notes about user-visible changes.
465 * read.c (struct vmodifiers): Remember what modifiers were seen.
466 (parse_var_assignment): New function to parse variable assignments.
467 (eval): Call the new function. Handle variable assignments earlier.
469 * variable.c (parse_variable_definition): Only parse; don't create var.
470 (assign_variable_definition): Call parse, then create the var.
472 2009-05-24 Paul Smith <psmith@gnu.org>
474 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
475 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
477 2009-03-14 Eli Zaretskii <eliz@gnu.org>
479 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
480 Fixes Savannah bug #25412.
482 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
483 prototype for xmalloc.
484 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
485 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
486 Loop over an array of extensions, instead of duplicating the same
487 code inline. Use SearchPath followed by CreateFile, instead of
488 the obsolete OpenFile. Fixes Savannah bug #17277.
489 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
490 to `find_file'. Fixes Savannah bug #25662.
492 2009-03-07 Eli Zaretskii <eliz@gnu.org>
494 * function.c (func_shell): Don't close pipedes[1] if it is -1.
495 Fixes Savannah bug #20495.
497 2009-02-28 Ralf Wildenhues <address@hidden>
499 * doc/make.texi (Instead of Execution): Document interaction of
500 -t with phony targets.
502 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
504 Introduce a new keyword "private" which applies to target-specific
505 variables and prevents their values from being inherited.
507 * variable.h (struct variable): Add private_var flag to each variable.
508 Add a flag to specify which list entry switches to the parent target.
509 * variable.c (define_variable_in_set): Initialize private_var flag.
510 (lookup_variable): Skip private variables in parent contexts.
511 (initialize_file_variables): Set next_is_parent appropriately.

514 (record_target_var): Set private_var.
515 * doc/make.texi (Suppressing Inheritance): Add documentation.
517 2008-10-26 Paul Smith <psmith@gnu.org>
519 * configure.in: Check for strndup().
520 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
522 * make.h: Rename savestring to xstrndup.
523 * commands.c (chop_commands): Ditto.
524 * function.c (func_foreach): Ditto.
525 * read.c (eval, record_files): Ditto.
526 * variable.c (define_variable_in_set): Ditto.
528 2008-09-30 Eli Zaretskii <eliz@gnu.org>
530 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
533 * w32/subproc/build.bat (GCCBuild): Likewise.
535 2008-09-30 David Russo <d-russo@ti.com> (tiny change)

585 (.PHONY): Add "html".

590 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with

621 2007-10-12 Eli Zaretskii <eliz@gnu.org>
623 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
624 a more complex value than a simple shell: if it's not a default

680 * read.c (eval): Remove the cmd_prefix characters from the command
681 scripts here, so they're not stored in the commands array at all,
682 rather than waiting and stripping them out during command construction.
683 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
685 2007-08-15 Paul Smith <psmith@gnu.org>

751 Dave Korn <dave.korn@artimi.com>
753 2007-05-08 Paul Smith <psmith@gnu.org>
755 Fix Savannah bug #19656:
757 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
759 * make.h: Change all case-insensitive string compares to use
760 strcasecmp() (from POSIX). If we don't have that but do have one
761 of the others, define strcasecmp to be one of those instead. If
762 we don't have any, declare a prototype for our own version.
764 * misc.c (strcasecmp): Use this if we can't find any native
765 case-insensitive string comparison function.
766 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
767 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
769 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
770 strcasecmp() instead of stricmp().
771 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
772 instead of strcmpi().
773 * acinclude.m4: Remove the strcasecmp() check from here.
775 2007-03-21 Paul Smith <psmith@gnu.org>
777 * configure.in: Don't turn on case-insensitive file system support
778 if --disable-... is given. Fixes Savannah bug #19348.
780 2007-03-19 Paul Smith <psmith@gnu.org>
782 * ALL: Use the strcache for all file name strings, or other
783 strings which we will never free. The goal is to save memory by
784 avoiding duplicate copies of strings. However, at the moment this
785 doesn't save much memory in most situations: due to secondary
786 expansion we actually save prerequisite lists twice (once before
787 the secondary expansion, and then again after it's been parsed
788 into individual file names in the dep list). We will resolve this
789 in a future change, by doing the parsing up-front for targets
790 where secondary expansion is not set.
792 Moving things into the strcache also allows us to use const
793 pointers in many more places.
795 2007-01-03 Paul Smith <psmith@gnu.org>
797 * make.h (ENULLLOOP): Reset errno after each failed invocation of
798 the function, not just the first. Fixes Savannah bug #18680.
800 2006-11-18 Paul Smith <psmith@gnu.org>
802 * strcache.c (strcache_add_len): Don't allocate a new buffer
803 unless the string is not already nil-terminated. Technically this
804 is a violation of the standard, since we may be passed an array
805 that is not long enough to test one past. However, in make this
806 is never true since we only use nil-terminated strings or
809 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
811 * main.c: New global cmd_prefix, defaults to '\t'.
812 * job.c (construct_command_argv_internal): Use cmd_prefix instead
816 (dir_contents_file_exists_p): Check for an error return from
817 readdir(), just in case.
819 * commands.c: Constified.
820 * default.c: Constified.
821 * expand.c: Constified.
822 * function.c: Partial constification.
823 * variable.c: Partial constification.

832 backslashes and drive letters as absolute.
834 2006-10-22 Paul Smith <psmith@gnu.org>
836 * main.c (struct command_switch): Use const and void*.
838 2006-10-21 Paul Smith <psmith@gnu.org>
841 * arscan.c: Constified.
843 2006-09-30 Paul Smith <psmith@gnu.org>
845 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
846 point to lastword since the example was updated.
847 Fixes Savannah bug #16304.
848 (Secondary Expansion): Correct example description.
849 Fixes Savannah bug #16468.
850 (Makefile Contents): Clarify that comments cannot appear within
851 variable references or function calls.
852 Fixes Savannah bug #16577.
853 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
854 Fixes Savannah bug #17701.
855 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
856 (Prerequisite Types): Added an example of using order-only
857 prerequisites. Fixes Savannah bug #17880.

899 * README.cvs: Add a reminder to notify the GNU translation robot.
901 * doc/make.texi: Change @direcategory (requested by Karl Berry).
903 2006-04-20 Paul D. Smith <psmith@gnu.org>

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

914 inner-scope variables don't mask outer-scope variables.
916 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1041 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1042 listed non-existent files as changed. Turns out there's a bug in
1043 the Linux kernel builds which means that this change causes
1044 everything to rebuild every time. We will re-introduce this fix
1045 in the next release, to give them time to fix their build system.
1046 Fixes Savannah bug #16002.
1047 Introduces Savannah bug #16051.

1066 * commands.c (set_file_variables): Realloc, not malloc, the static
1067 string values to avoid memory leaks.

1070 an initialized value.

1085 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1086 the calls to _beginthreadex.
1088 * expand.c (recursively_expand_for_file): Initialize `save' to
1089 prevent compiler warnings.
1091 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1093 * job.c (construct_command_argv_internal): Don't create a temporary
1094 script/batch file if we are under -n. Call _setmode to switch the
1095 script file stream to text mode.
1097 2006-02-17 Paul D. Smith <psmith@gnu.org>
1099 * variable.c (merge_variable_set_lists): Don't try to merge the
1100 global_setlist. Not only is this useless, but it can lead to
1101 circularities in the linked list, if global_setlist->next in one
1102 list gets set to point to another list which also ends in
1104 Fixes Savannah bug #15757.
1106 2006-02-15 Paul D. Smith <psmith@gnu.org>
1108 Fix for Savannah bug #106.
1110 * expand.c (expanding_var): Keep track of which variable we're
1111 expanding. If no variable is being expanded, it's the same as
1113 * make.h (expanding_var): Declare it.
1114 * expand.c (recursively_expand_for_file): Set expanding_var to the
1115 current variable we're expanding, unless there's no file info in
1116 it (could happen if it comes from the command line or a default
1117 variable). Restore it before we exit.
1118 * expand.c (variable_expand_string): Use the expanding_var file
1119 info instead of the reading_file info.
1120 * function.c (check_numeric): Ditto.
1122 (func_wordlist): Ditto.
1123 (func_error): Ditto.
1124 (expand_builtin_function): Ditto.
1125 (handle_function): Ditto.
1127 2006-02-14 Paul D. Smith <psmith@gnu.org>
1129 * read.c (eval): Even if the included filenames expands to the
1130 empty string we still need to free the allocated buffer.
1132 * implicit.c (pattern_search): If we allocated a variable set for
1133 an impossible file, free it.
1134 * variable.c (free_variable_set): New function.
1135 * variable.h: Declare it.
1137 * read.c (read_all_makefiles): Makefile names are kept in the
1138 strcache, so there's never any need to alloc/free them.
1141 * main.c (main): Add "archives" to the .FEATURES variable if
1142 archive support is enabled.
1143 * doc/make.texi (Special Variables): Document it.
1145 2006-02-13 Paul D. Smith <psmith@gnu.org>
1147 * implicit.c (pattern_search): Add checking for DOS pathnames to
1148 the pattern rule target LASTSLASH manipulation.
1149 Fixes Savannah bug #11183.

1153 * (ALL FILES): Updated copyright and license notices.
1155 2006-02-10 Paul D. Smith <psmith@gnu.org>
1157 A new internal capability: the string cache is a read-only cache
1158 of strings, with a hash table interface for fast lookup. Nothing
1159 in the cache will ever be freed, so there's no need for reference
1160 counting, etc. This is the beginning of a full solution for
1161 Savannah bug #15182, but for now we only store makefile names here.
1163 * strcache.c: New file. Implement a read-only string cache.
1164 * make.h: Add prototypes for new functions.
1165 * main.c (initialize_global_hash_tables): Initialize the string cache.
1166 (print_data_base): Print string cache stats.
1167 * read.c (eval_makefile): Use the string cache to store makefile
1168 names. Rewrite the string allocation to be sure we free everything.
1170 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1172 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1173 directory time stamp didn't change, except on FAT filesystems.
1174 Suggested by J. David Bryan <jdbryan@acm.org>.
1176 2006-02-09 Paul D. Smith <psmith@gnu.org>
1178 * function.c (func_or): Implement a short-circuiting OR function.
1179 (func_and): Implement a short-circuiting AND function.
1180 (function_table_init): Update the table with the new functions.
1181 * doc/make.texi (Conditional Functions): Changed the "if" section
1182 to one on general conditional functions. Added documentation for
1183 $(and ...) and $(or ...) functions.
1184 * NEWS: Note new $(and ...) and $(or ...) functions.
1186 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1188 * job.h (struct child): Add the dontcare bitfield.
1189 * job.c (new_job): Cache dontcare flag.
1190 * job.c (reap_children): Use cached dontcare flag instead of the
1191 one in struct file. Fixes Savannah bug #15641.
1193 2006-02-06 Paul D. Smith <psmith@gnu.org>
1195 * vpath.c (selective_vpath_search): If the file we find has a
1196 timestamp from -o or -W, use that instead of the real time.
1197 * remake.c (f_mtime): If the mtime is a special token from -o or
1198 -W, don't overwrite it with the real mtime.
1199 Fixes Savannah bug #15341.
1201 Updates from Markus Mauhart <qwe123@chello.at>:
1203 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1204 (process_signal, process_last_err, process_exit_code): Manage
1205 invalid handle values.
1206 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1207 manage invalid handles; remove them.

1215 to avoid walking the list every time we want to add a new one.
1216 Fixes Savannah bug #15533.
1217 * filedef.h (struct file): Add a new LAST pointer.
1219 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1220 the comparison. For 64-bits systems the result of the subtraction
1221 might not fit into an int. Use comparison instead.
1222 Fixes Savannah bug #15534.
1224 * doc/make.texi: Update the chapter on writing commands to reflect
1225 the changes made in 3.81 for backslash/newline and SHELL handling.
1227 2006-02-01 Paul D. Smith <psmith@gnu.org>
1229 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1245 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1247 * remake.c (update_goal_chain): Set g->changed instead of
1248 incrementing it, as it is only 8-bit wide, and could overflow if
1249 many commands got started in update_file.
1251 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1253 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1254 MAXIMUM_WAIT_OBJECTS.
1255 (process_wait_for_any_private): Change dimension of handles[]
1256 array to MAXIMUM_WAIT_OBJECTS.
1257 (process_used_slots): New function.
1258 (process_register): Don't register more processes than the
1259 available number of slots.
1260 (process_easy): Don't start new processes if all slots are used up.
1262 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1263 are already more children than sub_proc.c can handle, behave as if
1264 the load were too high.
1265 (start_job_command): Fix a typo in error message when process_easy
1268 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1270 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1271 the shell is not sh.exe.
1273 * job.c (create_batch_file): Renamed from create_batch_filename;
1274 all callers changed. Don't close the temporary file; return its
1275 file descriptor instead. New arg FD allows to return the file
1277 (construct_command_argv_internal): Use _fdopen instead of fopen to
1278 open the batch file.
1280 2006-01-04 Paul D. Smith <psmith@gnu.org>
1282 * readme.vms: Updates for case-insensitive VMS file systems from
1283 Hartmut Becker <Hartmut.Becker@hp.com>.
1284 * dir.c (vms_hash): Ditto.
1285 * vmsify.c (copyto): Ditto.

1303 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1304 disable warnings for MSC.
1305 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1307 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1309 * doc/make.texi (Execution): Add a footnote about changes in
1310 handling of backslash-newline sequences. Mention the differences
1311 on MS-DOS and MS-Windows.
1313 * NEWS: More details about building the MinGW port and a pointer
1314 to README.W32. Fix the section name that describes the new
1315 backward-incompatible processing of backslash-newline sequences.
1316 The special processing of SHELL set to "cmd" is only relevant to
1317 MS-Windows, not MS-DOS.
1319 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1321 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1322 to DWORD, to avoid compiler warnings.
1323 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1324 use %ld in format, to avoid compiler warnings.
1326 * doc/make.texi (Special Targets): Fix a typo.
1327 (Appending): Fix cross-reference to Setting.
1328 (Special Variables, Secondary Expansion, File Name Functions)
1329 (Flavor Function, Pattern Match, Quick Reference): Ensure two

1338 * read.c (record_target_var): Initialize variable's export field
1339 with v_default instead of leaving it "initialized" by whatever
1340 garbage happened to be on the heap.
1342 2005-12-12 Paul D. Smith <psmith@gnu.org>
1344 * make.1: Fix some display errors and document all existing options.
1345 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1347 2005-12-11 Paul D. Smith <psmith@gnu.org>
1349 * implicit.c (pattern_search): If 2nd expansion is not set for
1350 this implicit rule, replace the pattern with the stem directly,
1351 and don't re-expand the variable list. Along with the other
1352 .SECONDEXPANSION changes below, fixes bug #13781.
1354 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1356 * implicit.c (pattern_search): Mark other files that this rule
1357 builds as targets so that they are not treated as intermediates
1358 by the pattern rule search algorithm. Fixes bug #13022.
1360 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1362 * remake.c (notice_finished_file): Propagate the change of
1363 modification time to all the double-colon entries only if

1382 * read.c (record_files): Don't set deps flags if there are no deps.
1383 * maintMakefile: We only need to build the templates when we are
1384 creating a distribution, so don't do it for "all".
1386 2005-10-24 Paul D. Smith <psmith@gnu.org>
1388 Make secondary expansion optional: its enabled by declaring the
1389 special target .SECONDEXPANSION.
1391 * NEWS: Update information on second expansion capabilities.
1392 * doc/make.texi (Secondary Expansion): Document the
1393 .SECONDEXPANSION special target and its behavior.

1395 prerequisite list was found in a static pattern rule.
1396 (free_dep_chain): Declare a prototype.
1397 * file.c (parse_prereqs): New function: break out some complexity
1399 (expand_deps): If we aren't doing second expansion, replace % with
1400 the stem for static pattern rules. Call the new function.
1401 * filedef.h (parse_prereqs): Declare a prototype.
1402 * implicit.c (pattern_search): Initialize the new staticpattern
1404 * main.c (second_expansion): Declare a global variable to remember
1405 if the special target has been seen. Initialize the new
1406 staticpattern field for prerequisites.
1407 * make.h: Extern for second_expansion.
1408 * misc.c (free_dep_chain): New function: frees a struct dep list.
1409 * read.c (read_all_makefiles): Initialize the staticpattern field.
1410 (eval_makefile): Ditto.
1411 (record_files): Check for the .SECONDEXPANSION target and set
1412 second_expansion global if it's found.
1413 Use the new free_dep_chain() instead of doing it by hand.
1414 Set the staticpattern field for prereqs of static pattern targets.
1416 2005-10-16 Paul D. Smith <psmith@gnu.org>
1418 * main.c (main): Set CURDIR to be a file variable instead of a
1419 default, so that values of CURDIR inherited from the environment
1420 won't override the make value.
1422 2005-09-26 Paul D. Smith <psmith@gnu.org>
1424 * job.c (construct_command_argv_internal): If the line is empty
1425 remember to free the temporary argv strings.
1428 2005-09-16 Paul D. Smith <psmith@gnu.org>

1431 bit); set it appropriately.
1432 Reported by Mark Eichin <eichin@metacarta.com>
1434 2005-08-29 Paul D. Smith <psmith@gnu.org>
1436 * function.c (func_error): On Windows, output from $(info ...)
1437 seems to come in the wrong order. Try to force it with fflush().
1439 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1441 * read.c (record_files): Move code that sets stem for static
1442 pattern rules out of the if (!two_colon) condition so it is
1443 also executed for two-colon rules. Fixes Savannah bug #13881.
1445 2005-08-08 Paul D. Smith <psmith@gnu.org>
1447 * make.h: Don't test that __STDC__ is non-0. Some compilers

1453 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1454 conditional (slightly different version of a fix from Eli).
1456 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1457 If make is running in parallel without -k and two jobs die in a
1458 row, but not too close to each other, then make will quit without
1459 waiting for the rest of the jobs to die.
1461 * main.c (die): Don't reset err before calling reap_children() the
1462 second time: we still want it to be in the error condition.
1463 * job.c (reap_children): Use a static variable, rather than err,
1464 to control whether or not the error message should be printed.
1466 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1468 * w32/subproc/sub_proc.c: Include signal.h.
1469 (process_pipe_io, process_file_io): Pass a pointer to a local
1470 DWORD variable to GetExitCodeProcess. If the exit code is
1471 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1473 * job.c [WINDOWS32]: Include windows.h.
1474 (main_thread) [WINDOWS32]: New global variable.
1475 (reap_children) [WINDOWS32]: Get the handle for the main thread
1476 and store it in main_thread.
1478 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1479 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1480 doing anything else. When we are done, close the main thread
1481 handle and exit with status 130.
1483 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1485 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1488 * main.c (find_and_set_default_shell): If found a DOSish shell,
1489 set sh_found and the value of default_shell, and report the
1490 findings in debug mode.
1492 * job.c (construct_command_argv_internal): Check unixy_shell, not
1493 no_default_sh_exe, to decide whether to use Unixy or DOSish
1496 * README.W32: Update with info about the MinGW build.
1498 * build_w32.bat: Support MinGW.
1500 * w32/subproc/build.bat: Likewise.
1502 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1503 printing DWORD args.
1505 * function.c (windows32_openpipe): Fix format strings for printing
1508 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1510 (start_job_command): Fix format string for printing the result of
1512 (start_job_command) [WINDOWS32]: Do not define.
1513 (exec_command): Fix format string for printing HANDLE args.
1515 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1516 to avoid compiler warnings.
1517 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1518 (Note: some of these fixes were submitted independently by J. Grant)

1526 2005-07-15 Paul Smith <psmith@gnu.org>
1528 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1529 we don't have a POSIX shell, then revert to the old
1530 backslash-newline behavior (where they are stripped).
1533 2005-07-08 Paul D. Smith <psmith@gnu.org>
1535 * config.h.W32.template: Reorder to match the standard config.h,
1536 for easier comparisons.
1537 From J. Grant <jg@jguk.org>
1539 * maintMakefile: Remove .dep_segment before overwriting it, in
1540 case it's not writable or noclobber is set.
1541 * expand.c (variable_expand_string): Cast result of pointer
1542 arithmetic to avoid a warning.
1543 * main.c (switches): Add full-fledged final initializer.
1545 2005-07-06 Paul D. Smith <psmith@gnu.org>
1547 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1548 * signame.c (strsignal): If we found _sys_siglist[] or
1549 __sys_siglist[] use those instead of sys_siglist[].
1550 From Albert Chin <china@thewrittenword.com>
1552 2005-07-04 Paul D. Smith <psmith@gnu.org>
1554 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1555 globfree(); set up to use the GNU versions.
1556 From Martin Zinser <zinser@zinser.no-ip.info>

1566 * w32/subproc/build.bat: Ditto.
1568 2005-06-28 Paul D. Smith <psmith@gnu.org>
1570 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1571 declaration was checked but not present.
1573 2005-06-27 Paul D. Smith <psmith@gnu.org>
1575 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1576 to unsigned long. Fixes Savannah bug #13550.
1578 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1579 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.

1582 2005-06-26 Paul D. Smith <psmith@gnu.org>
1584 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1585 it if ANSI_STRING is not set.
1587 2005-06-25 Paul D. Smith <psmith@gnu.org>
1589 * read.c (eval): If no filenames are passed to any of the
1590 "include" variants, don't print an error.
1591 * doc/make.texi (Include): Document this.
1592 Fixes Savannah bug #1761.
1594 * job.c (construct_command_argv_internal): Sanitize handling of
1595 backslash/newline pairs according to POSIX: that is, keep the
1596 backslash-newline in the command script, but remove a following
1597 TAB character, if present. In the fast path, make sure that the
1598 behavior matches what the shell would do both inside and outside
1599 of quotes. In the slow path, quote the backslash and put a
1600 literal newline in the string.
1601 Fixes Savannah bug #1332.
1602 * doc/make.texi (Execution): Document the new behavior and give
1604 * NEWS: Make a note of the new behavior.
1606 * make.h [WINDOWS32]: #include <direct.h>.
1607 Fixes Savannah bug #13478.
1609 * remake.c (name_mtime): If the stat() of a file fails and the -L
1610 option was given and the file is a symlink, take the best mtime of
1611 the symlink we can get as the mtime of the file and don't fail.
1612 Fixes Savannah bug #13280.
1614 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1615 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1616 inside a variable reference. Make this function static as it's
1618 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1619 parsing an unexpanded line looking for semicolons.
1620 Fixes Savannah bug #1454.
1621 * misc.c (remove_comments): Move this to read.c and make it static
1622 as it's only used there. Call find_char_unquote() with new arg.
1623 * make.h: Remove prototypes for find_char_unquote() and
1624 remove_comments() since they're static now.
1626 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1627 its export flag and obtain its value. When we need to re-exec,
1628 increment the value and add it into the environment.
1629 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1630 * NEWS: Mention MAKE_RESTARTS.
1631 * main.c (always_make_set): New variable. Change the -B option to
1632 set this one instead.
1633 (main): When checking makefiles, only set always_make_flag if
1634 always_make_set is set AND the restarts flag is 0. When building
1635 normal targets, set it IFF always_make_set is set.
1636 (main): Avoid infinite recursion with -W, too: only set what-if
1637 files to NEW before we check makefiles if we've never restarted
1638 before. If we have restarted, set what-if files to NEW _after_ we
1640 Fixes Savannah bug #7566:
1642 2005-06-17 Paul D. Smith <psmith@gnu.org>
1644 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1645 in the prerequisites list.
1647 2005-06-12 Paul D. Smith <psmith@gnu.org>
1649 Fix Savannah bug # 1328.
1651 * configure.in: Check for atexit().
1652 * misc.c (close_stdout): Test stdout to see if writes to it have
1653 failed. If so, be sure to exit with a non-0 error code. Based on
1654 code found in gnulib.
1655 * make.h: Prototype.
1656 * main.c (main): Install close_stdout() with atexit().
1658 2005-06-10 Paul D. Smith <psmith@gnu.org>
1660 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1662 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1663 headers; make vmsWaitForChildren() static; extern vmsify().
1664 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1665 Don't create child_execute_job() here (it's in vmsjobs.c).
1666 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1668 2005-06-09 Paul D. Smith <psmith@gnu.org>
1670 * variable.c (push_new_variable_scope): File variables point
1671 directly to the global_setlist variable. So, inserting a new
1672 scope in front of that has no effect on those variables: they
1673 don't go through current_variable_set_list. If we're pushing a
1674 scope and the current scope is global, push it "the other way" so
1675 that the new setlist is in the global_setlist variable, and
1676 next points to a new setlist with the global variable set.
1677 (pop_variable_scope): Properly undo a push with the new
1679 Fixes Savannah bug #11913.
1681 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1683 * job.c (reap_children): Don't die of the command failed but
1684 the dontcare flag is set. Fixes Savannah bug #13216.
1686 * implicit.c (pattern_search): When creating a target from
1687 an implicit rule match, lookup pattern target and set precious
1688 flag in a newly created target. Fixes Savannah bug #13218.
1690 2005-05-13 Paul D. Smith <psmith@gnu.org>
1692 Implement "if... else if... endif" syntax.
1694 * read.c (eval): Push all checks for conditional words ("ifeq",
1695 "else", etc.) down into the conditional_line() function.
1696 (conditional_line): Rework to allow "else if..." clause. New
1697 return value -2 for lines which are not conditionals. The
1698 ignoring flag can now also be 2, which means "already parsed a
1699 true branch". If that value is seen no other branch of this
1700 conditional can be considered true. In the else parsing if there
1701 is extra text after the else, invoke conditional_line()
1702 recursively to see if it's another conditional. If not, it's an
1703 error. If so, raise the conditional value to this level instead
1704 of creating a new conditional nesting level. Special check for
1705 "else" and "endif", which aren't allowed on the "else" line.
1706 * doc/make.texi (Conditional Syntax): Document the new syntax.
1708 2005-05-09 Paul D. Smith <psmith@gnu.org>
1710 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1711 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1712 recurses to the w32 directory, even on non-Windows systems. Use
1713 the method suggested in the automake manual.
1714 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1715 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1717 2005-05-07 Paul D. Smith <psmith@gnu.org>
1719 * main.c (die): If we're dying with a fatal error (not that a
1720 command has failed), write back any leftover tokens before we go.
1722 * job.c (set_child_handler_action_flags): If there are jobs
1723 waiting for the load to go down, set an alarm to go off in 1
1724 second. This allows us to wake up from a potentially long-lasting
1725 read() and start a new job if the load has gone down. Turn it off
1727 (job_noop): Dummy signal handler function.
1728 (new_job): Invoke it with the new semantics.
1730 * docs/make.texi: Document secondary expansion. Various cleanups
1733 2005-05-03 Paul D. Smith <psmith@gnu.org>
1735 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1736 the targets which are to ultimately be made are called "goals";
1737 see the GNU make manual. Also, MAKECMDGOALS, etc.
1739 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1740 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1741 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1743 2005-05-02 Paul D. Smith <psmith@gnu.org>
1745 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1746 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1747 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1748 functions to vmsjobs.c. #include it into jobs.c.
1750 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1751 jobserver tokens. I found that this happens when an exported
1752 recursive variable contains a $(shell ...) function reference: in
1753 this situation we could "forget" to write back a token.
1755 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1756 we have. It's not reliable to depend on the number of children in
1757 our linked list so keep a separate count.
1758 (new_job): Check jobserver_tokens rather than children &&
1759 waiting_jobs. Increment jobserver_tokens when we get one.
1760 (free_child): If jobserver_tokens is 0, internal error. If it's
1761 >1, write a token back to the jobserver pipe (we don't write a
1762 token for the "free" job). Decrement jobserver_tokens.
1764 * main.c: Add variable master_job_slots.
1765 (main): Set it to hold the number of jobs requested if we're the
1766 master process, when using the jobserver.
1767 (die): Sanity checks: first test jobserver_tokens to make sure
1768 this process isn't holding any tokens we didn't write back.
1769 Second, if master_job_slots is set count the tokens left in the
1770 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1772 2005-04-24 Paul D. Smith <psmith@gnu.org>
1774 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1775 with -l# can lose jobserver tokens, because waiting jobs are not
1776 consulted properly when checking for the "free" token.
1778 * job.c (free_child): Count waiting_jobs as having tokens.
1779 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1780 handle jobs waiting for the load to drop.
1782 2005-04-23 Paul D. Smith <psmith@gnu.org>
1784 * main.c (main): Be careful to not core if a variable setting in
1785 the environment doesn't contain an '='. This is illegal but can
1786 happen in broken setups.
1787 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1789 2005-04-12 Paul D. Smith <psmith@gnu.org>
1791 The second expansion feature causes significant slowdown. Timing
1792 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1793 read the makefile before the feature, to 11+s to do the same
1794 operations after the feature. Additionally, memory usage
1795 increased drastically. To fix this I added some intelligence that
1796 avoids the overhead of the second expansion unless it's required.
1798 * dep.h: Add a new boolean field, need_2nd_expansion.
1800 * read.c (eval): When creating the struct dep for the target,
1801 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1802 (record_files): If there's a "%" in a static pattern rule, it gets
1803 converted to "$*" so set need_2nd_expansion to 1.
1805 * file.c (expand_deps): Rework to be more efficient. Only perform
1806 initialize_file_variables(), set_file_variables(), and
1807 variable_expand_for_file() if the need_2nd_expansion is set.
1809 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1810 (pattern_search): Ditto.
1811 * main.c (handle_non_switch_argument): Ditto.
1813 * read.c (read_all_makefiles): Ditto.
1814 (eval_makefile): Ditto.
1816 2005-04-07 Paul D. Smith <psmith@gnu.org>
1818 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1819 * variable.c (sync_Path_environment): Ditto.
1820 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1822 * main.c (main): Define the .FEATURES variable.
1823 * NEWS: Announce .FEATURES.
1824 * doc/make.texi (Special Variables): Document .FEATURES.
1826 * remake.c (check_dep): If a file is .PHONY, update it even if
1827 it's marked intermediate. Fixes Savannah bug #12331.
1829 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1831 * file.c (expand_deps): Factor out the second expansion and
1832 prerequisite line parsing logic from snap_deps().
1834 * file.c (snap_deps): Use expand_deps(). Expand and parse
1835 prerequisites of the .SUFFIXES special target first. Fixes
1836 Savannah bug #12320.
1838 2005-03-13 Paul D. Smith <psmith@gnu.org>
1840 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1843 2005-03-11 Paul D. Smith <psmith@gnu.org>
1845 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1846 available, not undefined (from Earnie Boyd).
1848 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1850 * implicit.c (pattern_search): Mark an intermediate target as
1851 precious if it happened to be a prerequisite of some (other)
1852 target. Fixes Savannah bug #12267.
1854 2005-03-09 Paul D. Smith <psmith@gnu.org>
1856 * read.c (eval_makefile): Add alloca(0).
1857 (eval_buffer): Ditto.
1859 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1861 * main.c (main): Use o_file instead of o_default when defining
1862 the .DEFAULT_TARGET special variable.
1863 * read.c (eval): Use define_variable_global() instead of
1864 define_variable() when setting new value for the .DEFAULT_TARGET
1865 special variable. Fixes Savannah bug #12266.
1867 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1869 * imlicit.c (pattern_search): Mark files for which an implicit
1870 rule has been found as targets. Fixes Savannah bug #12202.
1872 2005-03-04 Paul D. Smith <psmith@gnu.org>
1875 * doc/make.texi (Automatic Variables): Document $|.
1877 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1879 * read.c (record_files): Instead of substituting % with
1880 actual stem value in dependency list replace it with $*.
1881 This fixes stem triple expansion bug.
1883 * implicit.c (pattern_search): Copy stem to a separate
1884 buffer and make it a properly terminated string. Assign
1885 this buffer instead of STEM (which is not terminated) to
1886 f->stem. Instead of substituting % with actual stem value
1887 in dependency list replace it with $*. This fixes stem
1888 triple expansion bug.
1890 2005-03-01 Paul D. Smith <psmith@gnu.org>
1892 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1893 on Windows, as it takes a handle not a pid. Just exit.
1894 Fix from patch #3679, provided by Alessandro Vesely.
1896 * configure.in: Update check for sys_siglist[] from autoconf manual.
1897 * signame.c (strsignal): Update to use the new autoconf macro.
1899 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1901 * read.c (record_files): Add a check for the list of prerequisites
1902 of a static pattern rule being empty. Fixes Savannah bug #12180.
1904 2005-02-28 Paul D. Smith <psmith@gnu.org>
1906 * doc/make.texi (Text Functions): Update docs to allow the end
1907 ordinal for $(wordlist ...) to be 0.
1908 * function.c (func_wordlist): Fail if the start ordinal for
1909 $(wordlist ...) is <1. Matches documentation.
1910 Resolves Savannah support request #103195.
1912 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1913 previously we were stopping when !-q, exactly the opposite. This
1914 has been wrong since version 1.34, in 1994!
1915 (update_file): If we got an error don't break out to run more
1916 double-colon rules: just return immediately.
1917 Fixes Savannah bug #7144.
1919 2005-02-27 Paul D. Smith <psmith@gnu.org>
1921 * misc.c (end_of_token): Make argument const.
1922 * make.h: Update prototype.
1924 * function.c (abspath, func_realpath, func_abspath): Use
1925 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1926 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1927 * read.c (record_files): Ditto.
1928 * variable.c (do_variable_definition): Ditto.
1930 * function.c (func_error): Create a new function $(info ...) that
1931 simply prints the message to stdout with no extras.
1932 (function_table_init): Add new function to the table.
1933 * NEWS: Add $(info ...) reference.
1934 * doc/make.texi (Make Control Functions): Document it.
1936 New feature: if the system supports symbolic links, and the user
1937 provides the -L/--check-symlink-time flag, then use the latest
1938 mtime between the symlink(s) and the target file.
1940 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1941 readlink(). If both are available, define MAKE_SYMLINKS.
1942 * main.c: New variable: check_symlink_flag.
1943 (usage): Add a line for -L/--check-symlink-times to the help string.
1944 (switches): Add -L/--check-symlink-times command line argument.
1945 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1946 print a warning and disable it again.
1947 * make.h: Declare check_symlink_flag.
1948 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1949 if the file is a symlink then check each link in the chain and
1950 choose the NEWEST mtime we find as the mtime for the file. The
1951 newest mtime might be the file itself!
1952 * NEWS: Add information about this new feature.
1953 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1955 Avoid core dumps described in Savannah bug # 12124:
1957 * file.c: New variable snapped_deps remember whether we've run
1959 (snap_deps): Set it.
1960 * filedef.h: Extern it.
1961 * read.c (record_files): Check snapped_deps; if it's set then
1962 we're trying to eval a new target/prerequisite relationship from
1963 within a command script, which we don't support. Fatal.
1965 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1967 Implementation of the .DEFAULT_TARGET special variable.
1969 * read.c (eval): If necessary, update default_target_name when
1971 * read.c (record_files): Update default_target_file if
1972 default_target_name has changed.
1973 * main.c (default_target_name): Define.
1974 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1975 default_target_name is set use default_target_file as a root
1977 * filedef.h (default_target_name): Declare.
1978 * dep.h (free_dep_chain):
1979 * misc.c (free_dep_chain): Change to operate on struct nameseq
1980 and change name to free_ns_chain.
1981 * file.c (snap_deps): Update to use free_ns_chain.
1983 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1985 Implementation of the second expansion in explicit rules,
1986 static pattern rules and implicit rules.
1988 * read.c (eval): Refrain from chopping up rule's dependencies.
1989 Store them in a struct dep as a single dependency line. Remove
1990 the code that implements SySV-style automatic variables.
1992 * read.c (record_files): Adjust the code that handles static
1993 pattern rules to expand all percents instead of only the first
1994 one. Reverse the order in which dependencies are stored so that
1995 when the second expansion reverses them again they appear in
1996 the makefile order (with some exceptions, see comments in
1997 the code). Remove the code that implements SySV-style automatic
2000 * file.c (snap_deps): Implement the second expansion and chopping
2001 of dependency lines for explicit rules.
2003 * implicit.c (struct idep): Define an auxiliary data type to hold
2004 implicit rule's dependencies after stem substitution and
2007 * implicit.c (free_idep_chain): Implement.
2009 * implicit.c (get_next_word): Implement helper function for
2010 parsing implicit rule's dependency lines into words taking
2011 into account variable expansion requests. Used in the stem
2014 * implicit.c (pattern_search): Implement the second expansion
2015 for implicit rules. Also fixes bug #12091.
2017 * commands.h (set_file_variables): Declare.
2018 * commands.c (set_file_variables): Remove static specifier.
2020 * dep.h (free_dep_chain): Declare.
2021 * misc.c (free_dep_chain): Implement.
2023 * variable.h (variable_expand_for_file): Declare.
2024 * expand.c (variable_expand_for_file): Remove static specifier.
2026 * make.h (strip_whitespace): Declare.
2027 * function.c (strip_whitespace): Remove static specifier.
2029 2005-02-26 Paul D. Smith <psmith@gnu.org>
2031 * main.c (main): Check for ferror() when reading makefiles from stdin.
2032 Apparently some shells in Windows don't close pipes properly and
2035 2005-02-24 Jonathan Grant <jg@jguk.org>
2037 * configure.in: Add MinGW configuration options, and extra w32 code
2039 * Makefile.am: Add MinGW configuration options, and extra w32 code
2041 * main.c: Determine correct program string (after last \ without .exe).
2042 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2044 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2045 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2046 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2047 environment support.
2049 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2051 * function.c (func_shell): When initializing error_prefix, check
2052 that reading file name is not null. This fixes long-standing
2053 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2055 2005-02-09 Paul D. Smith <psmith@gnu.org>
2057 * maintMakefile: Update the CVS download URL to simplify them.
2058 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2059 downloading the .texi files from Savannah now.
2061 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2063 * main.c (handle_non_switch_argument): Only add variables to
2064 command_variables if they're not already there: duplicate settings
2065 waste space and can be confusing to read.
2067 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2068 this header is never included by non-WINDOWS32 code, and it
2069 requires <config.h> to define which isn't always included first.
2071 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2072 testing MINGW32 versions.
2074 * main.c (log_working_directory): flush stdout to be sure the WD
2075 change is printed before any stderr messages show up.
2077 2005-02-01 Paul D. Smith <psmith@gnu.org>
2079 * maintMakefile (po_repo): Update the GNU translation site URL.
2081 2004-12-01 Paul D. Smith <psmith@gnu.org>
2083 * main.c (main): Change char* env_shell to struct variable shell_var.
2084 * variable.c (target_environment): Use new shell_var.
2086 2004-11-30 Paul D. Smith <psmith@gnu.org>
2088 * configure.in: The old way we avoided creating build.sh from
2089 build.sh.in before build.sh.in exists doesn't work anymore; we
2090 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2091 the help!). This also keeps automake from complaining.
2092 * Makefile.am (README): Add a dummy target so automake won't
2093 complain that this file doesn't exist when we checkout from CVS.
2094 * maintMakefile (.dep_segment): Rewrite this rule since newer
2095 versions of automake don't provide DEP_FILES.
2097 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2099 Implementation of `realpath' and `abspath' built-in functions.
2101 * configure.in: Check for realpath.
2102 * function.c (abspath): Return an absolute file name that does
2103 not contain any `.' or `..' components, nor repeated `/'.
2104 * function.c (func_abspath): For each name call abspath.
2105 * function.c (func_realpath): For each name call realpath
2106 from libc or delegate to abspath if realpath is not available.
2107 * doc/make.texi (Functions for File Names): Document new functions.
2108 * doc/make.texi (Quick Reference): Ditto.
2110 2004-11-28 Paul D. Smith <psmith@gnu.org>
2112 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2113 arguments. Fixes bug #10252.
2115 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2117 * main.c (main): Set SHELL to v_noexport by default. Remember the
2118 original environment setting of SHELL in the env_shell variable.
2119 * main.h: Export new env_shell variable.
2120 * variable.c (target_environment): If we find a v_noexport
2121 variable for SHELL, add a SHELL variable with the env_shell value.
2122 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2123 * doc/make.texi (Variables/Recursion): Ditto.
2125 2004-11-28 Paul D. Smith <psmith@gnu.org>
2127 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2128 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2129 Patch by Alessandro Vesely.
2131 2004-11-12 Paul D. Smith <psmith@gnu.org>
2133 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2134 the command line if it's inside a string.
2135 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2137 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2139 * function.c (func_lastword): New function: return last word
2140 from the list of words.
2141 * doc/make.texi: Document $(lastword ). Fix broken links in
2142 Quick Reference section.
2144 2004-10-06 Paul D. Smith <psmith@gnu.org>
2146 Apply patch from Alessandro Vesely, provided with bug # 9748.
2147 Fix use of tmpnam() to work with Borland C.
2149 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2150 construction of a temporary filename, and call new function
2151 create_batch_filename().
2152 (create_batch_filename) [WINDOWS32]: New function to create a
2155 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2157 * read.c (record_target_var): Expand simple pattern-specific
2159 * variable.c (initialize_file_variables): Do not expand simple
2160 pattern-specific variable.
2162 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2164 * remake.c (update_file_1): When rebuilding makefiles inherit
2165 dontcare flag from a target that triggered update.
2167 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2169 * variable.c (initialize_file_variables): Mark pattern-specific
2170 variable as a per-target and copy export status.
2172 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2174 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2176 * implicit.c (pattern_search): When considering an implicit rule's
2177 prerequisite check that it is actually a target rather then
2178 just an entry in the file hashtable.
2180 2004-09-21 Paul D. Smith <psmith@gnu.org>
2182 * read.c (readstring): Fix some logic errors in backslash handling.
2183 (eval): Remove some unnecessary processing in buffer handling.
2184 (record_target_var): Assert that parse_variable_definition() succeeded.
2185 Reported by: Markus Mauhart <qwe123@chello.at>.
2187 * misc.c: Removed the sindex() function. All instances of this
2188 function were trivially replaceable by the standard strstr()
2189 function, and that function will always have better (or certainly
2190 no worse) performance than the very simple-minded algorithm
2191 sindex() used. This can matter with complex makefiles.
2192 * make.h: Remove the prototype for sindex().
2193 * function.c (subst_expand): Convert sindex() call to strstr().
2194 This means we no longer need to track the TLEN value so remove that.
2195 (func_findstring): Convert sindex() to strstr().
2196 * commands.c (chop_commands): Convert sindex() calls to strstr().
2197 Suggested by: Markus Mauhart <qwe123@chello.at>.
2199 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2200 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2201 If SHELL is set to CMD.EXE then assume it's batch-mode and
2202 non-unixy. I wrote the code differently from the patch, though,
2203 to make it safer. This also resolves bug #9174.
2205 2004-09-20 Paul D. Smith <psmith@gnu.org>
2207 * expand.c (variable_expand_string): Modify to invoke
2208 patsubst_expand() instead of subst_expand(); the latter didn't
2209 handle suffix patterns correctly.
2210 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2211 was used only from variable_expand_string() and is no longer used
2213 (func_subst): Ditto, on call to subst_expand().
2214 (patsubst_expand): Require the percent pointers to point to the
2215 character after the %, not to the % itself.
2216 * read.c (record_files): New call criteria for patsubst_expand().
2217 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2218 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2220 2004-09-19 Paul D. Smith <psmith@gnu.org>
2222 * function.c (subst_expand): Fix a check in by_word: look for a
2223 previous blank if we're beyond the beginning of the string, not
2224 the beginning of the word.
2225 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2227 2004-05-16 Paul D. Smith <psmith@gnu.org>
2229 * remake.c (update_goal_chain): Change the argument specifying
2230 whether we're rebuilding makefiles to be a global variable,
2231 REBUILDING_MAKEFILES.
2232 (complain): Extract the code that complains about no rules to make
2233 a target into a separate function.
2234 (update_file_1): If we tried to rebuild a file during the makefile
2235 rebuild phase and it was dontcare, then no message was printed.
2236 If we then try to build the same file during the normal build,
2237 print a message this time.
2238 (remake_file): Don't complain about un-remake-able files when
2239 we're rebuilding makefiles.
2241 2004-05-11 Paul D. Smith <psmith@gnu.org>
2243 * job.c (construct_command_argv_internal): OS/2 patches from
2244 Andreas Buening <andreas.buening@nexgo.de>.
2246 2004-05-10 Paul D. Smith <psmith@gnu.org>
2248 * remake.c (update_file): Don't walk the double-colon chain unless
2249 this is a double-colon rule. Fix suggested by Boris Kolpackov
2250 <boris@kolpackov.net>.
2252 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2253 * readme.vms: New section describing OpenVMS support and issues.
2254 * default.c (default_variables): Add support for IA64.
2255 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2256 without some privilege aborts make with the error
2257 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2258 pressing Ctrl+Y and the input device is no terminal. The change
2259 catches this error and just continues.
2261 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2263 2004-04-25 Paul D. Smith <psmith@gnu.org>
2265 * commands.c (set_file_variables): Set $< properly in the face of
2266 order-only prerequisites.
2267 Patch from Boris Kolpackov <boris@kolpackov.net>
2269 2004-04-21 Bob Byrnes <byrnes@curl.com>
2271 * main.c (main): Notice failures to remake makefiles.
2273 2004-03-28 Paul D. Smith <psmith@gnu.org>
2275 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2277 * job.c: No default shell for RISC OS.
2278 (load_too_high): Hard-code the return to 1.
2279 (construct_command_argv_internal): No sh_chars or sh_cmds.
2280 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2282 2004-03-20 Paul D. Smith <psmith@gnu.org>
2284 * variable.c (do_variable_definition): Don't append from the
2285 global set if a previous non-appending target-specific variable
2286 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2289 * expand.c (reference_variable): Don't give up on variables with
2290 no value that have the target-specific append flag set: they might
2291 have a value after all. Reported by Oliver Schmidt
2292 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2293 <nikulin@dx1cmd.inp.nsk.su>.
2295 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2296 refer to absolute pathnames in directories that don't exist: some
2297 portion of the makefile could create those directories before we
2298 match the pattern. Fixes bugs #775 and #108.
2300 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2302 * main.c (main): Free makefile_mtimes if we have any.
2303 * README.W32.template: Update documentation for the current status
2304 of the MS-Windows port.
2305 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2306 environment variable is sometimes already defined which causes the
2308 * main.c (debug_signal_handler): Only define this function if
2309 SIGUSR1 is available.
2311 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2313 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2314 * README.OS2.template: Documentation updates.
2315 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2316 link line for safety.
2317 * maintMakefile (build.sh.in): Remove an extraneous ")".
2318 * job.c (child_execute_job): Close saved FDs.
2319 * job.c (exec_command) [OS/2]: exec_command(): If the command
2320 can't be exec'ed and if the shell is not Unix-sh, then try again
2321 with argv = { "cmd", "/c", ... }. Normally, this code is never
2322 reached for the cmd shell unless the command really doesn't exist.
2323 (construct_command_argv_internal) [OS/2]: The code for cmd
2324 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2325 The CMD builtin commands are case insensitive so use strcasecmp().
2327 2004-03-19 Paul D. Smith <psmith@gnu.org>
2329 * read.c (do_define): Re-order line counter increment so the count
2330 is accurate (we were losing one line per define). Reported by
2331 Dave Yost <Dave@Yost.com>.
2333 2004-03-06 Paul D. Smith <psmith@gnu.org>
2335 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2337 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2338 * misc.c (message,error,fatal): Ditto.
2339 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2340 * config.h.W32.template: Ditto.
2341 * config.h-vms.template: Ditto.
2342 * config.ami.template: Ditto.
2344 2004-03-04 Paul D. Smith <psmith@gnu.org>
2346 * README.template: Add a note about broken /bin/sh on SunOS
2347 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2349 * misc.c (message, error, fatal): Don't use "..." if we're using
2350 varargs. ansi2knr should handle this but it doesn't work: it
2351 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2352 done. On many systems (SunOS for example) va_dcl is a #define.
2353 So, force the use of the non-"..." version on pre-ANSI compilers.
2355 * maintMakefile (sign-dist): Create some rules to help automate
2356 the new GNU ftp upload method.
2358 2004-02-24 Paul D. Smith <psmith@gnu.org>
2360 * config.h.W32.template: Add HAVE_STDARG_H
2361 * config.h-vms.template: Ditto.
2362 * config.ami.template: Ditto.
2364 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2366 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2367 * build_w32.bat: Remove extra "+".
2369 2004-02-23 Paul D. Smith <psmith@gnu.org>
2371 * make.h: Create an UNUSED macro to mark unused parameters.
2372 * (many): Clean up warnings by applying UNUSED, fixing
2373 signed/unsigned incompatibilities, etc.
2375 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2377 * filedef.h: Name the command_state enumeration.
2378 * file.c (set_command_state): Use the enumeration in the function
2381 * configure.in: Explicitly set SET_MAKE to empty, to disable
2382 MAKE=make even when no make already exists. Fix bug #3823.
2384 2004-02-22 Paul D. Smith <psmith@gnu.org>
2386 * maintMakefile: Perl script to clean up all non-CVS files. Use
2387 it on all the subdirectories for the cvs-clean target.
2389 * main.c (decode_switches): Require non-empty strings for all our
2390 string command-line options. Fixes Debian bug # 164165.
2392 * configure.in: Check for stdarg.h and varargs.h.
2393 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2394 for printing messages.
2395 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2400 A number of patches for OS/2 support from Andreas Buening
2401 <andreas.buening@nexgo.de>:
2403 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2404 disable the SIGCHLD handler.
2405 (reap_children) [OS/2]: Remove special handling of job_rfd.
2406 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2407 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2408 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2409 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2410 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2413 2004-02-21 Paul D. Smith <psmith@gnu.org>
2415 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2416 <mail@kristov.de> reports that if process_begin() fails we don't
2417 handle the error condition correctly in all cases.
2418 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2419 to have a newline on the message.
2421 * job.c (construct_command_argv_internal): Add "test" to UNIX
2422 sh_cmds[]. Fixes Savannah bug # 7606.
2424 2004-02-04 Paul D. Smith <psmith@gnu.org>
2426 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2427 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2428 Hartmut Becker <Hartmut.Becker@hp.com>.
2430 2004-01-21 Paul D. Smith <psmith@gnu.org>
2432 * job.c (load_too_high): Implement an algorithm to control the
2433 "thundering herd" problem when using -l to control job creation
2434 via the load average. The system only recomputes the load once a
2435 second but we can start many jobs in a second. To solve this we
2436 keep track of the number of jobs started in the last second and
2437 apply a weight to try to guess what a correct load would be.
2438 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2439 Also fixes bug #4693.
2440 (reap_children): Decrease the job count for this second.
2441 (start_job_command): Increase the job count for this second.
2443 * read.c (conditional_line): Expand the text after ifn?def before
2444 checking to see if it's a single word. Fixes bug #7257.
2446 2004-01-09 Paul D. Smith <psmith@gnu.org>
2448 * file.c (print_file): Recurse to print all targets in
2449 double-colon rules. Fixes bug #4518, reported (with patch) by
2450 Andrew Chatham <chatham@google.com>.
2452 2004-01-07 Paul D. Smith <psmith@gnu.org>
2454 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2455 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2456 AC_FUNC_SETVBUF_REVERSED.
2458 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2459 (MAKE Variable): Fix Savannah bug #4898.
2461 * job.c (construct_command_argv_internal): Add "!" to the list of
2462 shell escape chars. POSIX sh allows it to appear before a
2463 command, to negate the exit code. Fixes bug #6404.
2465 * implicit.c (pattern_search): When matching an implicit rule,
2466 remember which dependencies have the ignore_mtime flag set.
2467 Original fix provided in Savannah patch #2349, by Benoit
2468 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2470 2003-11-22 Paul D. Smith <psmith@gnu.org>
2472 * README.W32.template (Outputs): Clarification on -j with
2473 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2476 2003-11-02 Paul D. Smith <psmith@gnu.org>
2478 * function.c (func_if): Strip all the trailing whitespace from the
2479 condition, then don't expand it. Fixed bug # 5798.
2481 * expand.c (recursively_expand_for_file): If we're expanding a
2482 variable with no file context, then use the variable's context.
2485 2003-10-21 Paul D. Smith <psmith@gnu.org>
2487 * main.c (log_working_directory): Add newlines to printf()s.
2489 * README.cvs: Add a note to ignore warnings during autoreconf.
2491 * maintMakefile (po_repo): Set a new URL for PO file updates.
2492 (get-config/config.guess get-config/config.sub): Get these files
2493 from the Savannah config project instead of ftp.gnu.org.
2495 2003-10-05 Paul Eggert <eggert@twinsun.com>
2497 * main.c (main): Avoid potential subscript error if environ has
2500 2003-08-22 Paul D. Smith <psmith@gnu.org>
2502 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2503 systems which don't yet implement the C89 standard :-/.
2505 2003-07-18 Paul D. Smith <psmith@gnu.org>
2507 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2508 [WINDOWS32]: Initialize hash.
2510 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2512 * dir.c (read_dirstream): Provide a workaround for broken versions of
2513 the MinGW dirent structure.
2515 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2517 * w32/include/dirent.h: Add __MINGW32__ filter.
2519 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2521 * make.h: Add global declaration of *make_host.
2522 * main.c (print_usage): Remove local declaration of *make_host.
2523 (print_version): Display "This program built for ..." after Copyright
2526 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2528 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2529 execution of "makeinfo --html make.texi".
2531 2003-04-30 Paul D. Smith <psmith@gnu.org>
2533 * build.template: Make some changes to maybe allow this script to
2534 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2536 * README.OS2.template: New file for OS/2 support. Original
2537 contributed by Andreas Buening.
2538 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2541 2003-04-19 Paul D. Smith <psmith@gnu.org>
2543 Fix bug #1405: allow a target to match multiple pattern-specific
2546 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2547 variable.c, where they've always belonged.
2548 * rule.h: Move the prototypes and struct pattern_var as well.
2549 * variable.c (initialize_file_variables): Invoke
2550 lookup_pattern_var() in a loop, until no more matches are found.
2551 If a match is found, create a new variable set for the target's
2552 pattern variables. Then merge the contents of each matching
2553 pattern variable set into the target's pattern variable set.
2554 (lookup_pattern_var): Change this function to be usable
2555 in a loop. It takes a starting position: if NULL, start at the
2556 beginning; if non-NULL, start with the pattern variable after that
2557 position, and return the next matching pattern.
2558 (create_pattern_var): Create a unique instance of
2559 pattern-specific variables for every definition in the makefile.
2560 Don't combine the same pattern together. This allows us to
2561 process the variable handling properly even when the same pattern
2562 is used multiple times.
2563 (parse_variable_definition): New function: break out the parsing
2564 of a variable definition line from try_variable_definition.
2565 (try_variable_definition): Call parse_variable_definition to
2567 (print_variable_data_base): Print out pattern-specific variables.
2568 * variable.h (struct variable): Remember when a variable is
2569 conditional. Also remember its flavor.
2570 (struct pattern_var): Instead of keeping a variable set, we just
2571 keep a single variable for each pattern.
2572 * read.c (record_target_var): Each pattern variable contains only a
2573 single variable, not a set, so create it properly.
2574 * doc/make.texi (Pattern-specific): Document the new behavior.
2576 2003-04-17 Paul D. Smith <psmith@gnu.org>
2578 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2579 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2580 file/directory naming rules for VMS so I can't tell whether this
2583 2003-04-09 Paul D. Smith <psmith@gnu.org>
2585 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2586 DOS-style pathnames: backslash separators and drive specifiers.
2588 2003-03-28 Paul D. Smith <psmith@gnu.org>
2590 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2591 the intermediate flag on all targets. Fixes bug #2515.
2593 2003-03-24 Paul D. Smith <psmith@gnu.org>
2595 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2596 Upgrade to autoconf 2.57 and automake 1.7.3.
2598 * job.c: More OS/2 changes from Andreas Buening.
2600 * file.c (print_file): Fix variable initialization.
2603 * remake.c (notice_finished_file):
2605 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2606 some calls (like readdir()) return NULL in valid situations
2607 without resetting errno. Fixes bug #2846.
2609 2003-02-25 Paul D. Smith <psmith@gnu.org>
2611 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2613 * job.c (_is_unixy_shell) [OS/2]: New function.
2614 Set default shell to /bin/sh.
2615 (reap_children): Close the job_rfd pipe here since we don't use a
2617 (set_child_handler_action_flags): define this to empty on OS/2.
2618 (start_job_command): Close the jobserver pipe and use
2619 child_execute_job() instead of fork/exec.
2620 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2621 rather than exec'ing, then reconfigure stdin/stdout.
2622 (exec_command): Rewrite to use spawn instead of exec. Return the
2625 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2626 in DOS. Handle the TEMP environment variable as in DOS. Don't
2627 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2628 use -j in DOS mode. Use child_execute_job() instead of
2631 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2634 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2635 prototypes that return values.
2637 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2639 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2640 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2642 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2645 2003-02-24 Paul D. Smith <psmith@gnu.org>
2647 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2648 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2649 (child_execute_job) [VMS]: Handle error status properly.
2650 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2652 * function.c (func_shell): Use EINTRLOOP() while reading from the
2653 subshell pipe (Fixes bug #2502).
2654 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2656 * main.c (main): Ditto.
2658 2003-01-30 Paul D. Smith <psmith@gnu.org>
2660 * read.c (eval): eval() was not fully reentrant, because the
2661 collapsed buffer was static. Change it to be an automatic
2662 variable so that eval() can be invoked recursively.
2664 (eval): Apply patch # 1022: fix memory reference error on long
2665 target-specific variable lines.
2666 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2668 * function.c (check_numeric): Combine the is_numeric() function
2669 into this function, since it's only called from one place.
2670 Constify this function. Have it print the incorrect string in the
2671 error message. Fixes bug #2407.
2672 (strip_whitespace): Constify.
2673 (func_if): Constify.
2674 * expand.c (expand_argument): Constify.
2676 2003-01-29 Paul D. Smith <psmith@gnu.org>
2678 Fix bug # 2169, also reported by other people on various systems.
2680 * make.h: Some systems, such as Solaris and PTX, do not fully
2681 implement POSIX-compliant SA_RESTART functionality; important
2682 system calls like stat() and readdir() can still fail with EINTR
2683 even if SA_RESTART has been set on the signal handler. So,
2684 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2685 EINTR for system calls which return -1 or 0 (NULL), respectively,
2687 Also, remove the old atomic_stat()/atomic_readdir() and
2688 HAVE_BROKEN_RESTART handling.
2690 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2692 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2693 * remake.c (touch_file): Ditto.
2695 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2696 * read.c (construct_include_path): Ditto.
2697 * remake.c (name_mtime): Ditto.
2698 * vpath.c (selective_vpath_search): Ditto.
2699 * dir.c (find_directory): Ditto.
2700 (local_stat): Ditto.
2701 (find_directory): Use ENULLLOOP() to wrap opendir().
2702 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2704 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2705 atomic_readdir() handling.
2707 2003-01-22 Paul D. Smith <psmith@gnu.org>
2709 * function.c (func_call): Fix Bug #1744. If we're inside a
2710 recursive invocation of $(call ...), mask any of the outer
2711 invocation's arguments that aren't used by this one, so that this
2712 invocation doesn't "inherit" them accidentally.
2714 2002-12-05 Paul D. Smith <psmith@gnu.org>
2716 * function.c (subst_expand): Valery Khamenia reported a
2717 pathological performance hit when doing substitutions on very
2718 large values with lots of words: turns out we were invoking
2719 strlen() a ridiculous number of times. Instead of having each
2720 call to sindex() call strlen() again, keep track of how much of
2721 the text we've seen and pass the length to sindex().
2723 2002-11-19 Paul D. Smith <psmith@gnu.org>
2725 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2728 2002-11-16 Paul D. Smith <psmith@gnu.org>
2730 * NMakefile.template (OBJS): Add hash.c object file.
2731 * SMakefile.template (srcs): Ditto.
2732 * Makefile.ami (objs): Ditto.
2733 * build_w32.bat: Ditto.
2735 * Makefile.DOS.template: Remove extra dependencies.
2737 2002-10-25 Paul D. Smith <psmith@gnu.org>
2739 * expand.c (install_variable_buffer): New function. Install a new
2740 variable_buffer context and return the previous one.
2741 (restore_variable_buffer): New function. Free the current
2742 variable_buffer context and put a previously saved one back.
2743 * variable.h: Prototypes for {install,restore}_variable_buffer.
2744 * function.c (func_eval): Push a new variable_buffer context
2745 before we eval, then restore the old one when we're done.
2748 * read.c (install_conditionals): New function. Install a new
2749 conditional context and return the previous one.
2750 (restore_conditionals): New function. Free the current
2751 conditional context and put a previously saved one back.
2752 (eval): Use the {install,restore}_conditionals for "include"
2754 (eval_buffer): Use {install,restore}_conditionals to preserve the
2755 present conditional state before we evaluate the buffer.
2758 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2760 (Recursion): Add a variable index entry for CURDIR.
2762 * README.cvs: Update to appropriate versions.
2763 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2764 don't need to copy loadavg.c: automake is smart enough to create
2765 it for me. Still have a bug in automake related to ansi2knr tho.
2767 2002-10-14 Paul D. Smith <psmith@gnu.org>
2769 * remake.c (notice_finished_file): Only touch targets if they have
2770 at least one command (as per POSIX). Resolve Bug #1418.
2772 * *.c: Convert to using ANSI C-style function definitions.
2773 * Makefile.am: Enable the ansi2knr feature of automake.
2774 * configure.in: ditto.
2776 2002-10-13 Paul D. Smith <psmith@gnu.org>
2778 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2779 for automatic variable values like $^, etc. In the case of very
2780 large lists of prerequisites this causes problems. Instead reuse
2781 a static buffer (resizeable) for each variable.
2783 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2784 target-specific variable definitions. Check for it and set an
2786 (record_target_var): Set the export field to v_export if the
2787 "exported" flag is set.
2788 * doc/make.texi (Target-specific): Document the ability to use
2791 * doc/make.texi: Change the name of the section on automatic
2792 variables from "Automatic" to "Automatic Variables". Added text
2793 clarifying the scope of automatic variables.
2795 2002-10-04 Paul D. Smith <psmith@gnu.org>
2797 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2799 (record_files): Ditto.
2801 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2802 the search for the '=' to only within the enclosing parens.
2804 2002-10-03 Paul D. Smith <psmith@gnu.org>
2806 Version 3.80 released.
2808 * dir.c: Change hash functions to use K&R function definition style.
2809 * function.c: Ditto.
2811 * variable.c: Ditto.
2813 Update to automake 1.7.
2815 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2816 (pdf): Remove this target as automake now provides one.
2818 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2820 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2822 * makefile.com: Updates for GNU make 3.80.
2823 * makefile.vms: Ditto.
2825 2002-09-23 Paul D. Smith <psmith@gnu.org>
2827 * read.c (enum make_word_type): Remove w_comment.
2828 (get_next_mword): Don't treat comment characters as special; where
2829 this function is used we will never see a comment (it's stripped
2830 before we get here) and treating comments specially means that
2831 targets like "foo\#bar" aren't handled properly.
2833 2002-09-18 Paul D. Smith <psmith@gnu.org>
2835 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2837 * read.c (eval): Expansion of arguments to export/unexport was
2838 ignoring all arguments after the first one. Change the algorithm
2839 to expand the whole line once, then parse the results.
2841 2002-09-17 Paul D. Smith <psmith@gnu.org>
2843 Fix Bug #940 (plus another bug I found while looking at this):
2845 * read.c (record_target_var): enter_file() will add a new entry if
2846 it's a double-colon target: we don't want to do that in this
2847 situation. Invoke lookup_file() and only enter_file() if it does
2848 not already exist. If the file we get back is a double-colon then
2849 add this variable to the "root" double-colon target.
2851 * variable.c (initialize_file_variables): If this file is a
2852 double-colon target but is not the "root" target, then initialize
2853 the root and make the root's variable list the parent of our
2856 2002-09-13 Paul D. Smith <psmith@gnu.org>
2858 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2860 * hash.c (round_up_2): Get rid of a warning.
2862 2002-09-12 Paul D. Smith <psmith@gnu.org>
2864 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2865 so it doesn't complain about getloadavg.c.
2867 * commands.c (set_file_variables): Make sure we always alloca() at
2868 least 1 character for the value of $? (for '\0').
2870 2002-09-11 Paul D. Smith <psmith@gnu.org>
2872 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2873 macro to use RESULT instead of the incorrect _RESULT_.
2875 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2876 and atomic_readdir(). We need to #include dirent.h to get this to
2878 * misc.c (atomic_readdir): Fix typos.
2880 2002-09-10 Paul D. Smith <psmith@gnu.org>
2882 * read.c (eval): Expand variable lists given to export and
2883 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2884 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2886 * doc/make.texi (Variables/Recursion): Document this.
2887 (Conditional Syntax): And here.
2889 2002-09-09 Paul D. Smith <psmith@gnu.org>
2891 * configure.in: Check for memmove().
2893 2002-09-07 Paul D. Smith <psmith@gnu.org>
2895 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2896 Michael Sterrett <msterret@coat.com> reports that while it has
2897 SA_RESTART, it does not work properly.
2899 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2900 that invokes stat() and loops to do it again if it returns EINTR.
2901 (atomic_readdir): Ditto, with readdir().
2903 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2904 and readdir() to atomic_stat() and atomic_readdir().
2906 2002-09-04 Paul D. Smith <psmith@gnu.org>
2908 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2909 reports that GNU make sometimes doesn't recognize that targets can
2910 be made, when directories can be created as prerequisites. He
2911 reports that changing the order of predicates in the DEP->changed
2912 flag test so that lookup_file() is always performed, solves this
2915 2002-08-08 Paul D. Smith <psmith@gnu.org>
2917 * configure.in: Require a newer version of gettext.
2919 * misc.c (perror_with_name): Translate the format string (for
2920 right-to-left language support).
2921 (pfatal_with_name): Ditto.
2923 * main.c: Create a static array of strings to store the usage
2924 text. This is done to facilitate translations.
2925 (struct command_switch): Remove argdesc and description fields.
2926 (switches): Remove values for obsolete fields.
2927 (print_usage): Print each element of the usage array.
2929 * hash.c: Change function definitions to be K&R style.
2931 2002-08-02 Paul D. Smith <psmith@gnu.org>
2933 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2934 this one because it's too hard to get right. We'll look at it for
2936 * main.c (main): Don't create the .TARGETS variable.
2937 * variable.c (handle_special_var): Don't handle .TARGETS.
2939 2002-08-01 Paul D. Smith <psmith@gnu.org>
2941 * main.c (switches): Add a new option, -B (--always-make). If
2942 specified, make will rebuild all targets that it encounters even
2943 if they don't appear to be out of date.
2944 (always_make_flag): New flag.
2945 * make.h: Extern always_make_flag.
2946 * remake.c (update_file_1): Check always_make_flag; if it's set we
2947 will always rebuild any target we can, even if none of its
2948 prerequisites are newer.
2951 * doc/make.texi (Shell Function): Make it clear that make
2952 variables marked as "export" are not passed to instances of the
2955 Add new introspection variable .VARIABLES and .TARGETS.
2957 * variable.c (handle_special_var): New function. If the variable
2958 reference passed in is "special" (.VARIABLES or .TARGETS),
2959 calculate the new value if necessary. .VARIABLES is handled here:
2960 walk through the hash of defined variables and construct a value
2961 which is a list of the names. .TARGETS is handled by
2962 build_target_list().
2963 (lookup_variable): Invoke handle_special_var().
2964 * file.c (build_target_list): Walk through the hask of known files
2965 and construct a list of the names of all the ones marked as
2967 * main.c (main): Initialize them to empty (and as simple variables).
2968 * doc/make.texi (Special Variables): Document them.
2969 * NEWS: Mention them.
2971 * variable.h (struct variable): Add a new flag "exportable" which
2972 is true if the variable name is valid for export.
2973 * variable.c (define_variable_in_set): Set "exportable" when a new
2974 variable is defined.
2975 (target_environment): Use the "exportable" flag instead of
2976 re-checking the name here... an efficiency improvement.
2978 2002-07-31 Paul D. Smith <psmith@gnu.org>
2980 * config.h-vms.template: Updates to build on VMS. Thanks to
2981 Brian_Benning@aksteel.com for helping verify the build.
2982 * makefile.com: Build the new hash.c file.
2983 * hash.h: Use strcpmi(), not stricmp(), in the
2984 HAVE_CASE_INSENSITIVE_FS case.
2986 2002-07-30 Paul D. Smith <psmith@gnu.org>
2988 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2989 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2990 Reported by <Brian_Benning@aksteel.com>.
2992 2002-07-10 Paul D. Smith <psmith@gnu.org>
2994 * variable.c (pop_variable_scope): Remove variable made unused by
2995 new hash infrastructure.
2996 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2997 comparisons as well as name comparisons.
2998 * variable.h: Add a prototype for new hash_init_function_table().
2999 * file.c (lookup_file): Remove variables made unused by new hash
3001 * dir.c (directory_contents_hash_2): Missing return of hash value.
3002 (dir_contents_file_exists_p): Remove variables made unused by new
3003 hash infrastructure.
3006 Installed Greg McGary's integration of the hash functions from the
3007 GNU id-utils package:
3009 2002-07-10 Greg McGary <greg@mcgary.org>
3011 * scripts/functions/filter-out: Add literals to to the
3012 pattern space in order to add complexity, and trigger
3013 use of an internal hash table. Fix documentation strings.
3014 * scripts/targets/INTERMEDIATE: Reverse order of files
3015 passed to expected `rm' command.
3017 2002-07-10 Greg McGary <greg@mcgary.org>

3109 2002-07-10 Paul D. Smith <psmith@gnu.org>
3111 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3112 prerequisite list. A real SysV make will expand the entire
3113 prerequisites list _twice_: we don't do that as it's a big
3114 backward-compatibility problem. We only replace those specific
3117 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3118 references left in the list of prerequisites. Check for .POSIX as
3119 we record targets, so we can disable non-POSIX behavior while
3120 reading makefiles as well as running them.
3121 (eval): Check the prerequisite list to see if we have anything
3122 that looks like a SysV prerequisite variable reference.
3124 2002-07-09 Paul D. Smith <psmith@gnu.org>
3126 * doc/make.texi (Prerequisite Types): Add a new section describing
3127 order-only prerequisites.
3129 * read.c (uniquize_deps): If we have the same file as both a
3130 normal and order-only prereq, get rid of the order-only prereq,
3131 since the normal one supersedes it.
3133 2002-07-08 Paul D. Smith <psmith@gnu.org>
3135 * AUTHORS: Added Greg McGary to the AUTHORS file.
3136 * NEWS: Blurbed order-only prerequisites.
3137 * file.c (print_file): Show order-only deps properly when printing
3140 * maintMakefile: Add "update" targets for wget'ing the latest
3141 versions of various external files. Taken from Makefile.maint in
3144 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3145 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3147 2002-07-07 Paul D. Smith <psmith@gnu.org>
3149 * po/*.po: Remove. We'll use wget to retrieve them at release
3152 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3153 rather than a shell you get an exception. Make sure we look up
3154 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3156 * remake.c (notice_finished_file): Fix handling of -t flag.
3157 Patch provided by Henning Makholm <henning@makholm.net>.
3159 * implicit.c (pattern_search): Some systems apparently run short
3160 of stack space, and using alloca() in this function caused an
3161 overrun. I modified it to use xmalloc() on the two variables
3162 which seemed like they might get large. Fixes Bug #476.
3164 * main.c (print_version): Update copyright notice to conform with
3166 (print_usage): Update help output.
3168 * function.c (func_eval): Create a new make function, $(eval
3169 ...). Expand the arguments, put them into a buffer, then invoke
3170 eval_buffer() on the resulting string.
3171 (func_quote): Create a new function, $(quote VARNAME). Inserts
3172 the value of the variable VARNAME without expanding it any
3175 * read.c (struct ebuffer): Change the linebuffer structure to an
3176 "eval buffer", which can be either a file or a buffer.
3177 (eval_makefile): Move the code in the old read_makefile() which
3178 located a makefile into here: create a struct ebuffer with that
3179 information. Have it invoke the new function eval() with that
3181 (eval_buffer): Create a new function that creates a struct ebuffer
3182 that holds a string buffer instead of a file. Have it invoke
3183 eval() with that ebuffer.
3184 (eval): New function that contains the guts of the old
3185 read_makefile() function: this function parses makefiles. Obtains
3186 data to parse from the provided ebuffer. Some modifications to
3187 make the flow of the function cleaner and clearer. Still could
3188 use some work here...
3189 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3190 contents of the define/endef variable from the ebuffer.
3191 (readstring): Read the next line from a string-style ebuffer.
3192 (readline): Read the next line from an ebuffer. If it's a string
3193 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3196 * dep.h (eval_buffer): Prototype eval_buffer();
3198 * variable.c (do_variable_definition): Make sure that all
3199 non-target-specific variables are registered in the global set.
3200 If we're invoked from an $(eval ...) we might be inside a $(call
3201 ...) or other function which has pushed a variable scope; we still
3202 want to define our variables from evaluated makefile code in the
3205 2002-07-03 Greg McGary <greg@mcgary.org>
3207 * dep.h (struct dep) [ignore_mtime]: New member.
3208 [changed]: convert to a bitfield.
3209 * implicit.c (pattern_search): Zero ignore_mtime.
3210 * main.c (main, handle_non_switch_argument): Likewise.
3211 * rule.c (convert_suffix_rule): Likewise.
3212 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3213 (read_makefile): Parse '|' in prerequisite list.
3214 (uniquize_deps): Consider ignore_mtime when comparing deps.
3215 * remake.c (update_file_1, check_dep): Don't force remake for
3216 dependencies that have d->ignore_mtime.
3217 * commands.c (FILE_LIST_SEPARATOR): New constant.
3218 (set_file_variables): Don't include a
3219 prerequisite in $+, $^ or $? if d->ignore_mtime.
3222 2002-06-18 Paul D. Smith <psmith@gnu.org>
3224 * make.texinfo: Updates for next revision. New date/rev/etc.
3225 Recreate all Info menus. Change license on the manual to the GNU
3226 Free Documentation License. A number of typos.
3227 (Variables Simplify): Don't use "-" before it's defined.
3228 (Automatic Prerequisites): Rewrite the target example to work
3229 properly if the compile fails. Remove incorrect comments about
3230 how "set -e" behaves.
3231 (Text Functions): Move the "word", "wordlist", "words", and
3232 "firstword" functions here, from "File Name Functions".
3233 * make-stds.texi: Update from latest GNU version.
3234 * fdl.texi: (created) Import the latest GNU version.
3236 2002-06-06 Paul D. Smith <psmith@gnu.org>
3238 * variable.c (do_variable_definition): New function: extract the
3239 part of try_variable_definition() that actually sets the value
3240 into a separate function.
3241 (try_variable_definition): Call do_variable_definition() after
3242 parsing the variable definition string.
3243 (define_variable_in_set): Make the name argument const.
3245 * variable.h (enum variable_flavor): Make public.
3246 (do_variable_definition): Create prototype.
3248 * read.c (read_all_makefiles): Create a new built-in variable,
3250 (read_makefile): Add each makefile read in to this variable value.
3252 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3254 * Makefile.DOS.template: Tweak according to changes in the
3255 distribution. Add back the dependencies of *.o files.
3257 * configh.dos.template: Synchronize with config.h.in.
3259 2002-05-09 Paul D. Smith <psmith@gnu.org>
3261 * file.c (file_timestamp_now): Use K&R function declaration.
3263 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3264 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3265 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3266 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3267 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3268 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3269 nlist.n_name is a pointer rather than an array.
3271 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3272 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3273 * configure.in: Use it instead of the old version.
3275 * main.c (main): Prefer setvbuf() to setlinebuf().
3277 2002-05-08 Paul D. Smith <psmith@gnu.org>
3279 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3280 (loadavg_LDADD): Ditto.
3282 2002-04-29 Paul D. Smith <psmith@gnu.org>
3284 * expand.c (recursively_expand_for_file): Rename
3285 recursively_expand() to recursively_expand_for_file() and provide
3286 an extra argument, struct file. If the argument is provided, set
3287 the variable scope to that of the file before expanding.
3288 * variable.h (recursively_expand): Make this a macro that invokes
3289 recursively_expand_for_file() with a NULL file pointer.
3290 * variable.c (target_environment): Call the renamed function and
3291 provide the current file context.
3292 Fixes Debian bug #144306.
3294 2002-04-28 Paul D. Smith <psmith@gnu.org>
3296 Allow $(call ...) user-defined variables to be self-referencing
3297 without throwing an error. Allows implementation of transitive
3298 closures, among other possibly useful things.
3299 Requested by: Philip Guenther <guenther@sendmail.com>
3301 * variable.h (struct variable): Add a new field: exp_count, and
3302 new macros to hold its size and maximum value.
3303 (warn_undefined): Make this a macro.
3304 * variable.c (define_variable_in_set): Initialize it.
3305 * expand.c (recursively_expand): If we detect recursive expansion
3306 of a variable, check the exp_count field. If it's greater than 0
3307 allow the recursion and decrement the count.
3308 (warn_undefined): Remove this (now a macro in variable.h).
3309 * function.c (func_call): Before we expand the user-defined
3310 function, modify its exp_count field to contain the maximum
3311 number of recursive calls we'll allow. After the call, reset it
3314 2002-04-21 Paul D. Smith <psmith@gnu.org>
3316 Modified to use latest autoconf (2.53), automake (1.6.1), and
3317 gettext (0.11.1). We're using gettext's new "external" support,
3318 to avoid including libintl source with GNU make.
3320 * README.cvs: New file. Explain how to build GNU make from CVS.
3322 * configure.in: Modify checking for the system glob library.
3323 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3324 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3325 etc. will manage it correctly). Set an automake conditional
3326 USE_LOCAL_GLOB to decide whether to compile the glob library.
3328 * getloadavg.c (main): Include make.h in the "TEST" program to
3331 * Makefile.am: Remove special rules for loadavg. Replace them
3332 with Automake capabilities for building extra programs.
3334 * signame.c: This file does nothing if the system provide
3335 strsignal(). If not, it implements strsignal(). If the system
3336 doesn't define sys_siglist, then we make our own; otherwise we use
3338 * signame.h: Removed.
3340 * main.c (main): No need to invoke signame_init(). Update copyright.
3342 * ABOUT-NLS: Removed.
3343 * gettext.c: Removed.
3344 * gettext.h: Get a simplified copy from the gettext package.
3346 * i18n/*.po: Moved to po/.
3349 * config/*: Created. Contains package configuration helper files.
3350 * config.guess, config.sub: Moved to config directory.
3352 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3353 Rework to use new-style autoconf features. Use the "external"
3354 mode for gettext. Make the build.sh config file conditional on
3355 whether build.sh.in exists, to avoid autoconf errors.
3356 * acinclude.m4: Removed almost all macros as being obsolete.
3357 Rewrote remaining macros to use AC_DEFINE.
3358 * acconfig.h: Removed.
3360 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3361 conditional to handle customs support. Remove special handling
3364 2002-04-20 Paul D. Smith <psmith@gnu.org>
3366 * function.c (func_call): Don't mark the argument variables $1,
3367 etc. as recursive. They've already been fully expanded so
3368 there's no need to do it again, and doing so strips escaped $'s.
3369 Reported by Sebastian Glita <glseba@yahoo.com>.
3371 * remake.c (notice_finished_file): Walk through double-colon
3372 entries via the prev field, not the next field!
3373 Reported by Greg McGary <greg@mcgary.org>.
3375 * main.c (main): If the user specifies -q and asks for a specific
3376 target which is a makefile, we got an assert. In that case it
3377 turns out we should continue normally instead.
3379 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3381 * i18n/he.po: Installed a new translation.
3383 2002-01-07 Paul D. Smith <psmith@gnu.org>
3385 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3387 2001-12-04 Paul D. Smith <psmith@gnu.org>
3389 * i18n/ja.po: Installed an updated translation.
3391 2001-09-06 Paul Eggert <eggert@twinsun.com>
3393 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3394 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3396 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3398 (main): Get rid of any avoidable limit on stack size.
3400 2001-09-04 Paul D. Smith <psmith@gnu.org>
3402 * i18n/da.po: Installed an updated translation.
3404 2001-08-03 Paul D. Smith <psmith@gnu.org>
3406 * i18n/fr.po: Installed an updated translation.
3407 Resolves Debian bug #106720.
3409 2001-06-13 Paul D. Smith <psmith@gnu.org>
3411 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3414 2001-06-11 Paul D. Smith <psmith@gnu.org>
3416 * i18n/ko.po: Installed a new translation.
3418 2001-05-06 Paul D. Smith <psmith@gnu.org>
3420 Modify the EINTR handling.
3422 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3423 the way in which we manage the file descriptor/signal handler race
3424 trap to be more efficient.
3426 2001-05-06 Paul Eggert <eggert@twinsun.com>
3428 Restart almost all system calls that are interrupted, instead
3429 of worrying about EINTR. The lone exception is the read() for
3432 * configure.in (HAVE_SA_RESTART): New macro.
3433 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3434 * main.c (main): Use SA_RESTART instead of the old,
3435 nonstandard SA_INTERRUPT.
3437 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3438 * main.c (bsd_signal): New function or macro,
3439 if the implementation doesn't supply it.
3440 (The bsd_signal function will be in POSIX 1003.1-200x.)
3441 (HANDLESIG): Remove.
3442 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3444 * make.h (EINTR_SET): Remove.
3445 (SA_RESTART): New macro.
3447 * arscan.c (ar_member_touch): Don't worry about EINTR.
3448 * function.c (func_shell): Likewise.
3449 * job.c (reap_children, free_child, new_job): Likewise.
3450 * main.c (main): Likewise.
3451 * remake.c (touch_file, name_mtime): Likewise.
3453 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3454 if fstat failed with errno!=EINTR, the error was ignored.
3456 * job.c (set_child_handler_action_flags): New function.
3457 (new_job): Use it to temporarily clear the SIGCHLD action flags
3458 while reading the token.
3460 2001-05-02 Paul D. Smith <psmith@gnu.org>
3462 * job.c (start_job_command): Don't add define/endef per-line flags
3463 to the top-level flags setting.
3465 2001-04-03 Paul D. Smith <psmith@gnu.org>
3467 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3468 bit on error, so check for odd return values, not non-0 return
3470 (VMS_get_member_info): Calculate the timezone differences correctly.
3471 Reported by John Fowler <jfowler@nyx.net>.
3474 2001-03-14 Paul D. Smith <psmith@gnu.org>
3476 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3477 value before invoking define_variable().
3478 Reported by John Fowler <jfowler@nyx.net>.
3480 2001-02-07 Paul D. Smith <psmith@gnu.org>
3482 * read.c (record_target_var): If we reset the variable due to a
3483 command-line variable setting overriding it, turn off the "append"
3486 2001-01-17 Paul D. Smith <psmith@gnu.org>
3488 * variable.c (lookup_variable) [VMS]: When getting values from the
3489 environment, allocate enough space for the _value_ plus escapes,
3490 not enough space for the name plus escapes :-/.
3491 Reported by John Fowler <jfowler@nyx.net>.
3493 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3494 warnings that make generates, so it doesn't look like an error.
3495 Reported by Karl Berry <karl@gnu.org>.
3498 Fix for PR/2020: Rework appended target-specific variables. I'm
3499 fairly confident this algorithm is finally correct.
3501 * expand.c (allocated_variable_append): Rewrite. Instead of
3502 expanding each appended variable then adding all the expanded
3503 strings together, we append all the unexpanded values going up
3504 through the variable set contexts, then expand the final result.
3505 This behaves just like non-target-specific appended variable
3506 values, while the old way didn't in various corner cases.
3507 (variable_append): New function: recursively append the unexpanded
3508 value of a variable, walking from the outermost variable scope to
3510 * variable.c (lookup_variable): Remove the code that looked up the
3511 variable set list if the found variable was "append". We don't
3513 (lookup_variable_in_set): Make this non-static so we can use it
3515 (try_variable_definition): Use lookup_variable_in_set() rather
3516 than faking out current_variable_set_list by hand (cleanup).
3517 * variable.h: Add a prototype for the now non-static
3518 lookup_variable_in_set().
3520 2000-11-17 Paul D. Smith <psmith@gnu.org>
3522 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3523 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3524 before throwing a fit.
3526 2000-11-17 Paul D. Smith <psmith@gnu.org>
3528 * read.c (readline): CRLF calculations had a hole, if you hit the
3529 buffer grow scenario just right. Reworked the algorithm to avoid
3530 the need for len or lastlen at all. Problem description with
3531 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3533 2000-10-24 Paul D. Smith <psmith@gnu.org>
3535 * gettext.c (SWAP): Declare this with the prototype, otherwise
3536 some systems don't work (non-32-bit? Reported for Cray T3E).
3537 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3539 2000-10-05 Paul D. Smith <psmith@gnu.org>
3541 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3542 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3544 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3546 2000-09-22 Paul D. Smith <psmith@gnu.org>
3548 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3549 parts of the real gettext.h here, and we expect to really include
3550 the real gettext.h later. If we keep this #define, it's ignored.
3552 2000-09-21 Paul D. Smith <psmith@gnu.org>
3554 * main.c (log_working_directory): Rework the text to use complete
3555 sentences, to make life simpler for the translators.
3557 2000-08-29 Paul D. Smith <psmith@gnu.org>
3559 * file.c (remove_intermediates): Print a debug message before we
3560 remove intermediate files, so the user (if she uses -d) knows
3563 2000-08-21 Paul D. Smith <psmith@gnu.org>
3565 * variable.c (try_variable_definition): Change how we handle
3566 target-specific append variable defns: instead of just setting the
3567 value, expand it as an append _but_ only within the current
3568 target's context. Otherwise we lose all but the last value if the
3569 variable is appended more than once within the current target
3570 context. Fixes PR/1831.
3572 2000-08-16 Paul D. Smith <psmith@gnu.org>
3574 * function.c (func_shell): Nul-terminate the buffer before
3575 printing an exec error message (just in case it's not!).
3576 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3578 2000-07-25 Paul D. Smith <psmith@gnu.org>
3580 * job.c (construct_command_argv_internal): Add "~" to the list of
3581 sh_chars[] which disallow optimizing out the shell call.
3583 2000-07-23 Paul Eggert <eggert@twinsun.com>
3585 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3586 supersedes --disable-nsec-timestamps.
3587 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3588 * README: Remove --disable-nsec-timestamps.
3590 * filedef.h (struct file.low_resolution_time): New member.
3591 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3592 * remake.c (update_file_1):
3593 Avoid spurious rebuilds due to low resolution time stamps,
3594 generalizing the earlier code that applied only to archive members.
3595 (f_mtime): Archive members always have low resolution time stamps.
3597 * configure.in: Remove --disable-nsec-timestamps, as this has
3598 been superseded by .LOW_RESOLUTION_TIME.
3600 2000-07-23 Paul Eggert <eggert@twinsun.com>
3602 * configure.in (enable_nsec_timestamps): Renamed from
3603 make_cv_nsec_timestamps, since enable/disable options
3604 shouldn't be cached.
3606 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3607 and Paul Eggert <eggert@twinsun.com>
3609 * file.c (file_timestamp_now):
3610 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3611 so that clock_gettime is not linked unless needed.
3613 * filedef.h (FILE_TIMESTAMP_HI_RES):
3614 Remove definition; "configure" now does this.
3616 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3617 to before high resolution file timestamp check,
3618 since that check now uses uintmax_t.
3619 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3620 high resolution file timestamps.
3621 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3622 so that we don't link in clock_gettime unnecessarily.
3624 2000-07-17 Paul D. Smith <psmith@gnu.org>
3626 * i18n/ja.po: New version of the translation file.
3628 2000-07-07 Paul D. Smith <psmith@gnu.org>
3630 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3631 the offset calculation.
3632 (name_mtime): Replace EINTR test with EINTR_SET macro.
3634 2000-07-07 Paul Eggert <eggert@twinsun.com>
3638 * remake.c (update_file_1):
3639 Avoid spurious rebuilds of archive members due to their
3640 timestamp resolution being only one second.
3641 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3642 the clock's resolution being lower than file timestamps'.
3643 When warning about future timestamps, report only the discrepancy,
3644 not the absolute value of the timestamp and the current time.
3646 * file.c (file_timestamp_now): New arg RESOLUTION.
3647 * filedef.h (file_timestamp_now): Likewise.
3648 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3650 2000-07-05 Paul D. Smith <psmith@gnu.org>
3652 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3653 to listp. Fixes PR/1793.
3655 2000-06-26 Paul Eggert <eggert@twinsun.com>
3657 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3659 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3661 * remake.c (f_mtime): Remove unused var memtime.
3663 2000-06-25 Martin Buchholz <martin@xemacs.org>
3665 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3666 Ran spell-check on make.texinfo.
3668 2000-06-23 Paul D. Smith <psmith@gnu.org>
3670 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3671 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3672 * make.h: Define these macros.
3674 * Version 3.79.1 released.
3676 * configure.in: Add a new option, --disable-nsec-timestamps, to
3677 avoid using sub-second timestamps on systems that support it. It
3678 can lead to problems, e.g. if your makefile relies on "cp -p".
3679 * README.template: Document the issue with "cp -p".
3681 * config.guess, config.sub: Updated.
