1 2009-09-28 Paul Smith <psmith@gnu.org>
3 * doc/make.texi (Pattern Intro): Move the match algorithm
4 discussion into the "Pattern Match" node.
5 (Pattern Match): Expand on the pattern rule matching algorithm.
7 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
9 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
10 much of the command line on a single pass.
12 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
14 * varible.c (create_pattern_var): Insert variables into the
15 PATTERN_VARS list in the shortest patterns first order.
17 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
18 used to sort the rules.
19 (stemlen_compare): Compare two tryrule elements.
20 (pattern_search): Sort the rules so that they are in the shortest
23 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
25 * doc/make.texi (Pattern-specific Variable Values): Describe the
26 new pattern-specific variables application order.
27 (Introduction to Pattern Rules): Describe the new pattern rules
30 * NEWS: Add a note about the new behavior.
32 2009-09-27 Paul Smith <psmith@gnu.org>
34 * doc/make.texi (Double-Colon): Mention that pattern rules with
35 double-colons have a different meaning. Savannah bug #27497.
37 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
39 * configh.dos.template: Remove unconditional definition of
41 Include <sys/version.h> because ports of GCC 4.3.0 and later no
42 longer include it, so macros like __DJGPP_MINOR__ are no longer
43 defined automatically.
45 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
46 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
47 instead of using the hardcoded ones.
48 (SUBDIRS): doc subdir added.
49 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
50 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
51 create html formated docs. texi2html may not be ported to DOS.
52 (make.info, make.dvi, make.ps, make.html): Make targets depend on
54 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
55 -I switch to look in ./ instead of ./doc.
56 (html): Target depend on html-recursive instead of make_1.html.
57 (make_1.html): Removed.
58 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
59 (all-recursive): Allow for more than one subdir in the build
61 (mostlyclean-recursive, clean-recursive, distclean-recursive)
62 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
63 (tags-recursive): Allow for more than one subdir in the build
65 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
66 targets. Enter into doc/ to produce the targets.
67 (all-am): $(INFO_DEPS) replaced by info.
69 2009-09-26 Paul Smith <psmith@gnu.org>
71 * read.c (record_files): Use free_ns() to free struct nameseq.
74 * rule.c (freerule): Use free_dep_chain().
76 * read.c (record_files): Free FILENAMES chain for implicit rules.
77 (eval): Static pattern targets go into the string cache.
79 * function.c (string_glob): Free NAME in the nameseq chain.
81 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
83 * implicit.c (pattern_search): Terminate early if we haven't
84 found any rules to try (performance improvement).
86 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
88 * implicit.c (pattern_search): Merge three parallel arrays,
89 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
90 of struct TRYRULE. In the old version the latter two arrays
91 had insufficient length.
93 2009-09-24 Paul Smith <psmith@gnu.org>
95 * implicit.c (pattern_search): Add back support for order-only
96 prerequisites for secondary expansion implicit rules, that were
97 accidentally dropped. If we find a "|", enable order-only mode
98 and set IGNORE_MTIME on all deps that are seen afterward.
99 (pattern_search): Fix memory leaks: for intermediate files where
100 we've already set the file variable and pattern variable sets, be
101 sure to either save or free them as appropriate.
103 2009-09-23 Paul Smith <psmith@gnu.org>
105 Rework the way secondary expansion is stored, for efficiency.
106 This changes secondary expansion so that ONLY WHEN we know we have
107 a possibility of needing secondary expansion, do we defer the
108 secondary expansion. This means more parsing the deps but we use
109 a lot less memory (due to the strcache). Also, this fixes
112 * read.c (eval): Don't parse the dep string here anymore.
113 (record_files): Take the dep argument as an unparsed string. If
114 secondary expansion is enabled AND the prereq string has a '$' in
115 it, then set NEED_2ND_EXPANSION and keep the entire string.
116 Otherwise, parse the dep string here to construct the dep list
117 with the names in the strcache.
119 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
120 duplicate the name string (others are in the strcache).
122 * implicit.c: Remove struct idep and free_idep_chain(): unused.
123 (struct patdeps): New structure to store prereq information.
124 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
125 which prerequisites need expansion, and expand only those.
127 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
128 and enter_prereqs(). split_prereqs() takes a fully-expanded string
129 and splits it into a DEP list, handling order-only prereqs.
130 (enter_prereqs): This function enters a list of DEPs into the file
131 database. If there's a stem defined, expand any pattern chars.
132 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
133 set. Use the above functions.
134 (snap_deps): Only perform second expansion on prereqs that need it,
135 as defined by the NEED_2ND_EXPANSION flag.
136 (print_prereqs): New function to print the prereqs
137 (print_file): Call print_prereqs() rather than print inline.
139 * hash.h (STRING_COMPARE): Take advantage of strcache() by
141 (STRING_N_COMPARE): Ditto.
142 (ISTRING_COMPARE): Ditto.
144 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
145 (parse_file_seq): Return void*
146 * read.c (parse_file_seq): Return void*.
147 (eval): Invoke macroized version of parse_file_seq()
148 * default.c (set_default_suffixes): Ditto.
149 * file.c (split_prereqs): Ditto.
150 * function.c (string_glob): Ditto.
151 * main.c (main): Ditto.
152 * rule.c (install_pattern_rule): Ditto.
154 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
156 2009-09-16 Paul Smith <psmith@gnu.org>
158 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
160 * dep.h: Create alloc_dep() / free_dep() macros.
162 * implicit.c (pattern_search): Take advantage of the new
163 parse_file_seq() to add the directory prefix to each prereq.
165 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
166 all. Avoid reversing chains. Support adding prefixes.
167 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
168 cached/non-cached results.
169 (eval): Remove multi_glob() & invoke new parse_file_seq().
170 * rule.c (install_pattern_rule): Ditto.
171 * main.c (main): Ditto.
172 * implicit.c (pattern_search): Ditto.
173 * function.c (string_glob): Ditto.
174 * file.c (parse_prereqs): Ditto.
175 * default.c (set_default_suffixes): Ditto.
177 * variable.c (parse_variable_definition): Don't run off the end of
178 the string if it ends in whitespace (found with valgrind).
180 * commands.c (set_file_variables): Keep space for all targets in
181 $? if -B is given (found with valgrind).
183 2009-09-15 Paul Smith <psmith@gnu.org>
185 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
186 (xcalloc): Add new function.
187 * make.h: New declarations.
189 * ar.c (ar_glob_match): New calling method for concat().
190 * main.c (main): Ditto.
191 (decode_env_switches): Ditto.
192 * read.c (eval_makefile): Ditto.
193 (tilde_expand): Ditto.
194 (parse_file_seq): Ditto.
195 * variable.c (target_environment): Ditto.
196 (sync_Path_environment): Ditto.
198 * ar.c (ar_glob_match): Use xcalloc().
199 * dir.c (file_impossible): Ditto.
200 * file.c (enter_file): Ditto.
201 * job.c (new_job): Ditto.
202 * read.c (parse_file_seq): Ditto.
203 * vmsfunctions.c (opendir): Ditto.
205 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
207 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
208 inside the loop that looks up environment for PATH.
210 2009-08-31 Eli Zaretskii <eliz@gnu.org>
212 * function.c (windows32_openpipe): Update envp after calling
213 sync_Path_environment.
215 2009-08-02 Paul Smith <psmith@gnu.org>
217 * remake.c (notice_finished_file): Ensure file->cmds is not null
218 before looping through them. Fixes Savannah bug #21824.
220 * doc/make.texi (Wildcard Examples): Clarify when objects is
221 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
222 (Include): Clarify the behavior of -include.
223 Fixes Savannah bug #18963.
225 2009-08-01 Paul Smith <psmith@gnu.org>
227 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
228 etc. come on the command line. Fixes Savannah bug #27093.
230 * expand.c (expand_argument): If the argument is large enough use
231 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
233 * variable.c (do_variable_definition): Avoid using alloca() to
234 hold values, which can be large. Fixes Savannah bug #23960.
236 * job.c (new_job): Use memmove() instead of strcpy() since both
237 pointers are in the same memory block. Fixes Savannah bug #27148.
238 Patch by Petr Machata.
240 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
242 * job.c (construct_command_argv_internal): Add "ulimit" and
243 "unset" to the sh_cmds for Unixy shells.
245 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
248 that set make_cv_sys_gnu_glob, so they are also correctly set
249 when the cache has been populated before.
251 2009-07-04 Eli Zaretskii <eliz@gnu.org>
253 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
254 exist, as realpath(3) does where it's supported.
256 2006-07-04 Eli Zaretskii <eliz@gnu.org>
258 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
259 (abspath): Support systems that define HAVE_DOS_PATHS (have
260 drive letters in their file names). Use IS_PATHSEP instead of a
261 literal '/' comparison. Fixes Savannah bug #26886.
263 2009-06-14 Paul Smith <psmith@gnu.org>
265 * remake.c (update_file_1): Remember the original file we marked
266 as updating, so we can clear that flag again. If we find a target
267 via vpath, FILE might change.
268 (check_dep): Ditto. Fixes Savannah bug #13529.
269 Patch by Reid Madsen <reid.madsen@tek.com>.
271 2009-06-13 Paul Smith <psmith@gnu.org>
273 * doc/make.texi (MAKEFILES Variable): Be explicit that files
274 included by MAKEFILES cannot give default goals.
275 * read.c (eval): If set_default is not set, pass the no-default-goal
276 value when we read included makefiles. Fixes Savannah bug #13401.
278 * ar.c (ar_name): Ensure that targets with empty parens aren't
279 considered archive member references: archive members must have a
280 non-empty "member" string. Fixes Savannah bug #18435.
282 * function.c (string_glob): Rely on multi_glob() to determine
283 whether files exist or not. Remove call to file_exists_p() which
284 is not always correct. Fixes Savannah bug #21231.
285 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
286 then only files that really exist will be returned.
287 * dep.h: Add new argument to multi_glob().
288 * rule.c (install_pattern_rule): Ditto.
289 * read.c (eval): Ditto.
290 * main.c (main): Ditto.
291 * implicit.c (pattern_search): Ditto.
292 * file.c (parse_prereqs): Ditto.
293 * default.c (set_default_suffixes): Ditto.
295 2009-06-09 Paul Smith <psmith@gnu.org>
297 * commands.c (set_file_variables): If always_make_flag is set,
298 always add the prereq to $?. Fixes Savannah bug #17825.
300 * remake.c (update_file_1): When rebuilding deps of FILE, also try
301 to rebuild the deps of all the also_make targets for that file.
302 Fixes Savannah bug #19108.
304 * implicit.c (pattern_search): Undo test for is_target, added by
305 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
306 Rule Search Algorithm". Fixes Savannah bug #17752.
308 * main.c (clean_jobserver): Clear the jobserver_fds options and
309 set job_slots to the default when we clean up.
310 (define_makeflags): Return the new MAKEFLAGS value.
311 (main): Reset MAKEFLAGS in the environment when we re-exec.
312 Fixes Savannah bug #18124.
314 2009-06-08 Paul Smith <psmith@gnu.org>
316 * read.c (eval): Collapse continuations post-semicolon on target-
317 specific variables. Fixes Savannah bug #17521.
319 2009-06-07 Paul Smith <psmith@gnu.org>
321 * job.c (reap_children): For older systems without waitpid() (are
322 there any of these left?) run wait(2) inside EINTRLOOP to handle
323 EINTR errors. Fixes Savannah bug #16401.
325 * (various): Debug message cleanup. Fixes Savannah bug #16469.
327 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
329 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
330 not the end, to catch second expansion $(eval ...) defining new
331 target/prereq relationships during snap_deps.
332 Fixes Savannah bug #24622.
334 * read.c (record_files): The second-expansion "f->updating" hack
335 was not completely correct: if assumed that the target with
336 commands always had prerequisites; if one didn't then the ordering
337 was messed up. Fixed for now to use f->updating to decide whether
338 to preserve the last element in the deps list... but this whole
339 area of constructing and reversing the deps list is too confusing
340 and needs to be reworked. Fixes Savannah bug #21198.
342 2009-06-06 Paul Smith <psmith@gnu.org>
344 * hash.c (hash_insert): Remove useless test for NULL.
345 Fixes Savannah bug #21823.
347 * make.h: Move SET_STACK_SIZE determination to make.h.
348 * main.c (main): New global variable, STACK_LIMIT, holds the
349 original stack limit when make was started.
350 * job.c (start_job_command): Reset the stack limit, if we changed it.
351 Fixes Savannah bug #22010.
353 * remake.c (check_dep): Only set the target's state to not-started
354 if it's not already running. Found this while testing -j10 builds
355 of glibc: various targets were being rebuilt multiple times.
356 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
359 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
360 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
363 2009-06-04 Paul Smith <psmith@gnu.org>
365 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
367 * maintMakefile: Modify access of config and gnulib Savannah
368 modules to use GIT instead of CVS.
370 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
371 Fixes Savannah bug #24655.
373 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
374 this can happen during some invocations of $(eval ...) for example.
375 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
377 2009-06-02 Paul Smith <psmith@gnu.org>
379 * configure.in: Check for fileno()
380 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
381 for the makefile file so invocations of $(shell ...) don't inherit it.
382 Fixes Savannah bug #24277.
384 2009-06-01 Paul Smith <psmith@gnu.org>
386 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
387 expansion was handled incorrectly. Rework the default goal
388 handling to save the variable only. Remove default_goal_file and
390 * read.c (eval): Check default_goal_var, not default_goal_name.
391 * read.c (record_target_var): Don't check default_goal_file here.
393 2009-05-31 Paul Smith <psmith@gnu.org>
395 * main.c (main): Expand the .DEFAULT_GOAL variable before using
396 it, and if the multi_glob() returns nothing (say it expanded to
397 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
399 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
400 $(and ..) to the reference. Fixes Savannah bug #25694.
402 * make.1: Be clear that some recipes will be executed even with -n.
403 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
405 * doc/make.texi (Override Directive): Make more clear how
406 overrides and appends interact.
407 Elucidates part of Savannah bug #26207.
409 * read.c (record_target_var): Don't reset the origin on
410 target-specific variables; try_variable_definition() will handle
411 this correctly. Fixes Savannah bug #26207.
413 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
414 Fixes Savannah bug #25712.
416 * implicit.c (pattern_search): Keep a pointer to the beginning of
417 the filename and save that instead of the constructed pointer.
418 Fixes Savannah bug #26593.
419 Patch by Mark Seaborn <mrs@mythic-beasts.com>
421 2009-05-30 Paul Smith <psmith@gnu.org>
423 * doc/make.texi (Multi-Line): Add a description of the new abilities
424 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
425 "command sequence" vs. "recipe" syntax.
426 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
427 after a define, to create variables with those flavors.
429 2009-05-25 Paul Smith <psmith@gnu.org>
431 Reworked the parser for variable assignments to allow multiple
432 modifiers, and in any order. Also allows variable and
433 prerequisites to be modifier names ('export', 'private', etc.)
435 * NEWS: Add notes about user-visible changes.
437 * read.c (struct vmodifiers): Remember what modifiers were seen.
438 (parse_var_assignment): New function to parse variable assignments.
439 (eval): Call the new function. Handle variable assignments earlier.
441 * variable.c (parse_variable_definition): Only parse; don't create var.
442 (assign_variable_definition): Call parse, then create the var.
444 2009-05-24 Paul Smith <psmith@gnu.org>
446 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
447 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
449 2009-03-14 Eli Zaretskii <eliz@gnu.org>
451 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
452 Fixes Savannah bug #25412.
454 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
455 prototype for xmalloc.
456 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
457 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
458 Loop over an array of extensions, instead of duplicating the same
459 code inline. Use SearchPath followed by CreateFile, instead of
460 the obsolete OpenFile. Fixes Savannah bug #17277.
461 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
462 to `find_file'. Fixes Savannah bug #25662.
464 2009-03-07 Eli Zaretskii <eliz@gnu.org>
466 * function.c (func_shell): Don't close pipedes[1] if it is -1.
467 Fixes Savannah bug #20495.
469 2009-02-28 Ralf Wildenhues <address@hidden>
471 * doc/make.texi (Instead of Execution): Document interaction of
472 -t with phony targets.
474 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
476 Introduce a new keyword "private" which applies to target-specific
477 variables and prevents their values from being inherited.
479 * variable.h (struct variable): Add private_var flag to each variable.
480 Add a flag to specify which list entry switches to the parent target.
481 * variable.c (define_variable_in_set): Initialize private_var flag.

500 2008-09-30 Eli Zaretskii <eliz@gnu.org>
502 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
505 * w32/subproc/build.bat (GCCBuild): Likewise.
507 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
509 * job.c (construct_command_argv_internal): Avoid extra backslash
510 in batch-mode Unixy shells. Under DB_JOBS, display the contents
513 2008-05-31 Eli Zaretskii <eliz@gnu.org>
515 * README.W32.template: Remove obsolete text about non-support for
516 -jN without Unixy shell. Remove obsolete text about not supplying
517 Visual Studio project files (we do supply them). Modify text to
518 prefer GCC builds to MSC builds.
520 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
522 * doc/make.texi (Empty Targets): Fix typo.

562 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
563 HAVE_DECL_SYS_SIGLIST.
565 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
566 build does not use child_execute_job.
568 * variable.c (define_automatic_variables) [__MSDOS__]: Always
569 export the SHELL environment variable to the child.
571 2007-12-22 Eli Zaretskii <eliz@gnu.org>

593 2007-10-12 Eli Zaretskii <eliz@gnu.org>
595 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
596 a more complex value than a simple shell: if it's not a default
597 shell now then expand it and see if is a default shell then.
599 2007-10-10 Eli Zaretskii <eliz@gnu.org>
601 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
602 pathnames, with const strings.
603 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
604 from the template (used for building from CVS, not a dist).

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

651 * main.c (main): Create the .RECIPEPREFIX special variable.
652 * read.c (eval): Remove the cmd_prefix characters from the command
653 scripts here, so they're not stored in the commands array at all,
654 rather than waiting and stripping them out during command construction.
655 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
657 2007-08-15 Paul Smith <psmith@gnu.org>
659 * doc/make.texi (GNU Free Documentation License): The fdl.texi
660 file has had the section info removed, so add some to make.texi

723 Dave Korn <dave.korn@artimi.com>
725 2007-05-08 Paul Smith <psmith@gnu.org>
727 Fix Savannah bug #19656:
729 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
731 * make.h: Change all case-insensitive string compares to use
732 strcasecmp() (from POSIX). If we don't have that but do have one
733 of the others, define strcasecmp to be one of those instead. If
734 we don't have any, declare a prototype for our own version.
736 * misc.c (strcasecmp): Use this if we can't find any native
737 case-insensitive string comparison function.
738 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
739 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
741 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
742 strcasecmp() instead of stricmp().
743 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
744 instead of strcmpi().
745 * acinclude.m4: Remove the strcasecmp() check from here.
747 2007-03-21 Paul Smith <psmith@gnu.org>
749 * configure.in: Don't turn on case-insensitive file system support
750 if --disable-... is given. Fixes Savannah bug #19348.
752 2007-03-19 Paul Smith <psmith@gnu.org>
754 * ALL: Use the strcache for all file name strings, or other
755 strings which we will never free. The goal is to save memory by
756 avoiding duplicate copies of strings. However, at the moment this
757 doesn't save much memory in most situations: due to secondary
758 expansion we actually save prerequisite lists twice (once before
759 the secondary expansion, and then again after it's been parsed
760 into individual file names in the dep list). We will resolve this
761 in a future change, by doing the parsing up-front for targets
762 where secondary expansion is not set.
764 Moving things into the strcache also allows us to use const
765 pointers in many more places.
767 2007-01-03 Paul Smith <psmith@gnu.org>
769 * make.h (ENULLLOOP): Reset errno after each failed invocation of
770 the function, not just the first. Fixes Savannah bug #18680.
772 2006-11-18 Paul Smith <psmith@gnu.org>
774 * strcache.c (strcache_add_len): Don't allocate a new buffer
775 unless the string is not already nil-terminated. Technically this
776 is a violation of the standard, since we may be passed an array
777 that is not long enough to test one past. However, in make this
778 is never true since we only use nil-terminated strings or
781 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
783 * main.c: New global cmd_prefix, defaults to '\t'.
784 * job.c (construct_command_argv_internal): Use cmd_prefix instead
788 (dir_contents_file_exists_p): Check for an error return from
789 readdir(), just in case.
791 * commands.c: Constified.
792 * default.c: Constified.
793 * expand.c: Constified.
794 * function.c: Partial constification.
795 * variable.c: Partial constification.
796 * vmsify.c: Constification. Hard to test this but I hope I didn't

801 2006-11-16 Eli Zaretskii <eliz@gnu.org>
803 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
804 backslashes and drive letters as absolute.
806 2006-10-22 Paul Smith <psmith@gnu.org>
808 * main.c (struct command_switch): Use const and void*.
810 2006-10-21 Paul Smith <psmith@gnu.org>
813 * arscan.c: Constified.
815 2006-09-30 Paul Smith <psmith@gnu.org>
817 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
818 point to lastword since the example was updated.
819 Fixes Savannah bug #16304.
820 (Secondary Expansion): Correct example description.
821 Fixes Savannah bug #16468.
822 (Makefile Contents): Clarify that comments cannot appear within
823 variable references or function calls.
824 Fixes Savannah bug #16577.
825 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
826 Fixes Savannah bug #17701.
827 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
828 (Prerequisite Types): Added an example of using order-only
829 prerequisites. Fixes Savannah bug #17880.
830 (Rule Syntax): "lise" -> "list"
831 (Multiple Rules): ... -> @dots{}

871 * README.cvs: Add a reminder to notify the GNU translation robot.
873 * doc/make.texi: Change @direcategory (requested by Karl Berry).
875 2006-04-20 Paul D. Smith <psmith@gnu.org>
877 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
878 that don't have extended grep.
879 (cvsclean): Use $(PERL) instead of perl.
881 2006-04-09 Paul D. Smith <psmith@gnu.org>
883 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
885 * expand.c, implicit.c, main.c, read.c: Rename variables so that
886 inner-scope variables don't mask outer-scope variables.
888 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

949 2006-03-23 Paul D. Smith <psmith@gnu.org>

955 Fixes Savannah bug #16166.
957 * misc.c (log_access): Takes a const char *.

1013 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1014 listed non-existent files as changed. Turns out there's a bug in
1015 the Linux kernel builds which means that this change causes
1016 everything to rebuild every time. We will re-introduce this fix
1017 in the next release, to give them time to fix their build system.
1018 Fixes Savannah bug #16002.
1019 Introduces Savannah bug #16051.

1036 2006-02-19 Paul D. Smith <psmith@gnu.org>
1038 * commands.c (set_file_variables): Realloc, not malloc, the static
1039 string values to avoid memory leaks.
1041 * expand.c (recursively_expand_for_file): Only set reading_file to
1042 an initialized value.
1044 * implicit.c (pattern_search): We need to make a copy of the stem
1045 if we get it from an intermediate dep, since those get freed.
1047 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1049 (enter_file) [VMS]: Ditto.

1054 * job.c (construct_command_argv_internal): Fix last change.
1056 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1057 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1058 the calls to _beginthreadex.
1060 * expand.c (recursively_expand_for_file): Initialize `save' to
1061 prevent compiler warnings.
1063 2006-02-18 Eli Zaretskii <eliz@gnu.org>

1073 circularities in the linked list, if global_setlist->next in one
1074 list gets set to point to another list which also ends in

1080 Fix for Savannah bug #106.

1083 expanding. If no variable is being expanded, it's the same as
1085 * make.h (expanding_var): Declare it.
1086 * expand.c (recursively_expand_for_file): Set expanding_var to the
1087 current variable we're expanding, unless there's no file info in
1088 it (could happen if it comes from the command line or a default
1089 variable). Restore it before we exit.
1090 * expand.c (variable_expand_string): Use the expanding_var file
1091 info instead of the reading_file info.
1092 * function.c (check_numeric): Ditto.
1094 (func_wordlist): Ditto.
1095 (func_error): Ditto.
1096 (expand_builtin_function): Ditto.
1097 (handle_function): Ditto.
1099 2006-02-14 Paul D. Smith <psmith@gnu.org>
1101 * read.c (eval): Even if the included filenames expands to the
1102 empty string we still need to free the allocated buffer.
1104 * implicit.c (pattern_search): If we allocated a variable set for
1105 an impossible file, free it.
1106 * variable.c (free_variable_set): New function.
1107 * variable.h: Declare it.
1109 * read.c (read_all_makefiles): Makefile names are kept in the
1110 strcache, so there's never any need to alloc/free them.
1113 * main.c (main): Add "archives" to the .FEATURES variable if
1114 archive support is enabled.
1115 * doc/make.texi (Special Variables): Document it.
1117 2006-02-13 Paul D. Smith <psmith@gnu.org>
1119 * implicit.c (pattern_search): Add checking for DOS pathnames to
1120 the pattern rule target LASTSLASH manipulation.
1121 Fixes Savannah bug #11183.
1123 2006-02-11 Paul D. Smith <psmith@gnu.org>
1125 * (ALL FILES): Updated copyright and license notices.
1127 2006-02-10 Paul D. Smith <psmith@gnu.org>
1129 A new internal capability: the string cache is a read-only cache
1130 of strings, with a hash table interface for fast lookup. Nothing
1131 in the cache will ever be freed, so there's no need for reference
1132 counting, etc. This is the beginning of a full solution for
1133 Savannah bug #15182, but for now we only store makefile names here.
1135 * strcache.c: New file. Implement a read-only string cache.
1136 * make.h: Add prototypes for new functions.
1137 * main.c (initialize_global_hash_tables): Initialize the string cache.
1138 (print_data_base): Print string cache stats.
1139 * read.c (eval_makefile): Use the string cache to store makefile
1140 names. Rewrite the string allocation to be sure we free everything.
1142 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1144 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1145 directory time stamp didn't change, except on FAT filesystems.

1148 2006-02-09 Paul D. Smith <psmith@gnu.org>
1150 * function.c (func_or): Implement a short-circuiting OR function.
1151 (func_and): Implement a short-circuiting AND function.
1152 (function_table_init): Update the table with the new functions.
1153 * doc/make.texi (Conditional Functions): Changed the "if" section
1154 to one on general conditional functions. Added documentation for
1155 $(and ...) and $(or ...) functions.
1156 * NEWS: Note new $(and ...) and $(or ...) functions.
1158 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1160 * job.h (struct child): Add the dontcare bitfield.
1161 * job.c (new_job): Cache dontcare flag.
1162 * job.c (reap_children): Use cached dontcare flag instead of the
1163 one in struct file. Fixes Savannah bug #15641.
1165 2006-02-06 Paul D. Smith <psmith@gnu.org>
1167 * vpath.c (selective_vpath_search): If the file we find has a
1168 timestamp from -o or -W, use that instead of the real time.
1169 * remake.c (f_mtime): If the mtime is a special token from -o or
1170 -W, don't overwrite it with the real mtime.
1171 Fixes Savannah bug #15341.
1173 Updates from Markus Mauhart <qwe123@chello.at>:
1175 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1177 invalid handle values.
1178 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1179 manage invalid handles; remove them.

1187 to avoid walking the list every time we want to add a new one.
1188 Fixes Savannah bug #15533.
1189 * filedef.h (struct file): Add a new LAST pointer.
1191 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1192 the comparison. For 64-bits systems the result of the subtraction
1193 might not fit into an int. Use comparison instead.
1194 Fixes Savannah bug #15534.
1196 * doc/make.texi: Update the chapter on writing commands to reflect
1197 the changes made in 3.81 for backslash/newline and SHELL handling.

1217 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1219 * remake.c (update_goal_chain): Set g->changed instead of
1220 incrementing it, as it is only 8-bit wide, and could overflow if
1221 many commands got started in update_file.
1223 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1225 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1226 MAXIMUM_WAIT_OBJECTS.
1227 (process_wait_for_any_private): Change dimension of handles[]
1228 array to MAXIMUM_WAIT_OBJECTS.

1234 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1235 are already more children than sub_proc.c can handle, behave as if
1236 the load were too high.
1237 (start_job_command): Fix a typo in error message when process_easy
1240 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1242 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1243 the shell is not sh.exe.
1245 * job.c (create_batch_file): Renamed from create_batch_filename;
1246 all callers changed. Don't close the temporary file; return its
1247 file descriptor instead. New arg FD allows to return the file
1249 (construct_command_argv_internal): Use _fdopen instead of fopen to
1250 open the batch file.
1252 2006-01-04 Paul D. Smith <psmith@gnu.org>
1254 * readme.vms: Updates for case-insensitive VMS file systems from
1255 Hartmut Becker <Hartmut.Becker@hp.com>.

1275 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1276 disable warnings for MSC.
1277 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1279 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1281 * doc/make.texi (Execution): Add a footnote about changes in
1282 handling of backslash-newline sequences. Mention the differences
1283 on MS-DOS and MS-Windows.
1285 * NEWS: More details about building the MinGW port and a pointer
1286 to README.W32. Fix the section name that describes the new
1287 backward-incompatible processing of backslash-newline sequences.
1288 The special processing of SHELL set to "cmd" is only relevant to
1289 MS-Windows, not MS-DOS.
1291 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1293 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1294 to DWORD, to avoid compiler warnings.
1295 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1296 use %ld in format, to avoid compiler warnings.
1298 * doc/make.texi (Special Targets): Fix a typo.
1299 (Appending): Fix cross-reference to Setting.
1300 (Special Variables, Secondary Expansion, File Name Functions)

1310 * read.c (record_target_var): Initialize variable's export field
1311 with v_default instead of leaving it "initialized" by whatever
1312 garbage happened to be on the heap.
1314 2005-12-12 Paul D. Smith <psmith@gnu.org>
1316 * make.1: Fix some display errors and document all existing options.
1317 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1319 2005-12-11 Paul D. Smith <psmith@gnu.org>
1321 * implicit.c (pattern_search): If 2nd expansion is not set for
1322 this implicit rule, replace the pattern with the stem directly,
1323 and don't re-expand the variable list. Along with the other
1324 .SECONDEXPANSION changes below, fixes bug #13781.
1326 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1328 * implicit.c (pattern_search): Mark other files that this rule
1329 builds as targets so that they are not treated as intermediates
1330 by the pattern rule search algorithm. Fixes bug #13022.
1332 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1334 * remake.c (notice_finished_file): Propagate the change of
1335 modification time to all the double-colon entries only if

1354 * read.c (record_files): Don't set deps flags if there are no deps.
1355 * maintMakefile: We only need to build the templates when we are
1356 creating a distribution, so don't do it for "all".
1358 2005-10-24 Paul D. Smith <psmith@gnu.org>
1360 Make secondary expansion optional: its enabled by declaring the
1361 special target .SECONDEXPANSION.
1363 * NEWS: Update information on second expansion capabilities.
1364 * doc/make.texi (Secondary Expansion): Document the
1365 .SECONDEXPANSION special target and its behavior.

1367 prerequisite list was found in a static pattern rule.
1368 (free_dep_chain): Declare a prototype.
1369 * file.c (parse_prereqs): New function: break out some complexity
1371 (expand_deps): If we aren't doing second expansion, replace % with
1372 the stem for static pattern rules. Call the new function.
1373 * filedef.h (parse_prereqs): Declare a prototype.
1374 * implicit.c (pattern_search): Initialize the new staticpattern
1376 * main.c (second_expansion): Declare a global variable to remember
1377 if the special target has been seen. Initialize the new
1378 staticpattern field for prerequisites.
1379 * make.h: Extern for second_expansion.
1380 * misc.c (free_dep_chain): New function: frees a struct dep list.
1381 * read.c (read_all_makefiles): Initialize the staticpattern field.
1382 (eval_makefile): Ditto.
1383 (record_files): Check for the .SECONDEXPANSION target and set
1384 second_expansion global if it's found.
1385 Use the new free_dep_chain() instead of doing it by hand.
1386 Set the staticpattern field for prereqs of static pattern targets.
1388 2005-10-16 Paul D. Smith <psmith@gnu.org>
1390 * main.c (main): Set CURDIR to be a file variable instead of a
1391 default, so that values of CURDIR inherited from the environment
1392 won't override the make value.
1394 2005-09-26 Paul D. Smith <psmith@gnu.org>
1396 * job.c (construct_command_argv_internal): If the line is empty
1397 remember to free the temporary argv strings.
1400 2005-09-16 Paul D. Smith <psmith@gnu.org>
1402 * job.c (start_job_command): The noerror flag is a boolean (single
1403 bit); set it appropriately.
1404 Reported by Mark Eichin <eichin@metacarta.com>
1406 2005-08-29 Paul D. Smith <psmith@gnu.org>
1408 * function.c (func_error): On Windows, output from $(info ...)
1409 seems to come in the wrong order. Try to force it with fflush().
1411 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1413 * read.c (record_files): Move code that sets stem for static
1414 pattern rules out of the if (!two_colon) condition so it is
1415 also executed for two-colon rules. Fixes Savannah bug #13881.
1417 2005-08-08 Paul D. Smith <psmith@gnu.org>
1419 * make.h: Don't test that __STDC__ is non-0. Some compilers
1420 (Windows for example) set it to 0 to denote "ISO C + extensions".
1423 2005-08-07 Paul D. Smith <psmith@gnu.org>
1425 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1426 conditional (slightly different version of a fix from Eli).
1428 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1429 If make is running in parallel without -k and two jobs die in a
1430 row, but not too close to each other, then make will quit without
1431 waiting for the rest of the jobs to die.
1433 * main.c (die): Don't reset err before calling reap_children() the
1434 second time: we still want it to be in the error condition.
1435 * job.c (reap_children): Use a static variable, rather than err,
1436 to control whether or not the error message should be printed.
1438 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1440 * w32/subproc/sub_proc.c: Include signal.h.
1441 (process_pipe_io, process_file_io): Pass a pointer to a local
1442 DWORD variable to GetExitCodeProcess. If the exit code is
1443 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1445 * job.c [WINDOWS32]: Include windows.h.
1446 (main_thread) [WINDOWS32]: New global variable.
1447 (reap_children) [WINDOWS32]: Get the handle for the main thread
1448 and store it in main_thread.
1450 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1451 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1452 doing anything else. When we are done, close the main thread
1453 handle and exit with status 130.
1455 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1457 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1460 * main.c (find_and_set_default_shell): If found a DOSish shell,
1461 set sh_found and the value of default_shell, and report the
1462 findings in debug mode.
1464 * job.c (construct_command_argv_internal): Check unixy_shell, not
1465 no_default_sh_exe, to decide whether to use Unixy or DOSish
1468 * README.W32: Update with info about the MinGW build.
1470 * build_w32.bat: Support MinGW.
1472 * w32/subproc/build.bat: Likewise.
1474 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1475 printing DWORD args.
1477 * function.c (windows32_openpipe): Fix format strings for printing
1480 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1482 (start_job_command): Fix format string for printing the result of
1484 (start_job_command) [WINDOWS32]: Do not define.
1485 (exec_command): Fix format string for printing HANDLE args.
1487 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1488 to avoid compiler warnings.
1489 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1490 (Note: some of these fixes were submitted independently by J. Grant)

1494 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1495 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1496 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1498 2005-07-15 Paul Smith <psmith@gnu.org>
1500 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1501 we don't have a POSIX shell, then revert to the old
1502 backslash-newline behavior (where they are stripped).
1505 2005-07-08 Paul D. Smith <psmith@gnu.org>
1507 * config.h.W32.template: Reorder to match the standard config.h,
1508 for easier comparisons.
1509 From J. Grant <jg@jguk.org>
1511 * maintMakefile: Remove .dep_segment before overwriting it, in
1512 case it's not writable or noclobber is set.
1513 * expand.c (variable_expand_string): Cast result of pointer
1514 arithmetic to avoid a warning.
1515 * main.c (switches): Add full-fledged final initializer.
1517 2005-07-06 Paul D. Smith <psmith@gnu.org>
1519 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1520 * signame.c (strsignal): If we found _sys_siglist[] or
1521 __sys_siglist[] use those instead of sys_siglist[].
1522 From Albert Chin <china@thewrittenword.com>
1524 2005-07-04 Paul D. Smith <psmith@gnu.org>
1526 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1527 globfree(); set up to use the GNU versions.
1528 From Martin Zinser <zinser@zinser.no-ip.info>
1530 2005-07-03 Paul D. Smith <psmith@gnu.org>
1532 From J. Grant <jg@jguk.org>:

1538 * w32/subproc/build.bat: Ditto.
1540 2005-06-28 Paul D. Smith <psmith@gnu.org>
1542 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1543 declaration was checked but not present.
1545 2005-06-27 Paul D. Smith <psmith@gnu.org>
1547 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1548 to unsigned long. Fixes Savannah bug #13550.
1550 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1551 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1552 Fixes Savannah bug #13551.
1554 2005-06-26 Paul D. Smith <psmith@gnu.org>
1556 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1557 it if ANSI_STRING is not set.
1559 2005-06-25 Paul D. Smith <psmith@gnu.org>
1561 * read.c (eval): If no filenames are passed to any of the
1562 "include" variants, don't print an error.
1563 * doc/make.texi (Include): Document this.
1564 Fixes Savannah bug #1761.
1566 * job.c (construct_command_argv_internal): Sanitize handling of
1567 backslash/newline pairs according to POSIX: that is, keep the
1568 backslash-newline in the command script, but remove a following
1569 TAB character, if present. In the fast path, make sure that the
1570 behavior matches what the shell would do both inside and outside
1571 of quotes. In the slow path, quote the backslash and put a
1572 literal newline in the string.
1573 Fixes Savannah bug #1332.
1574 * doc/make.texi (Execution): Document the new behavior and give
1576 * NEWS: Make a note of the new behavior.
1578 * make.h [WINDOWS32]: #include <direct.h>.
1579 Fixes Savannah bug #13478.
1581 * remake.c (name_mtime): If the stat() of a file fails and the -L
1582 option was given and the file is a symlink, take the best mtime of
1583 the symlink we can get as the mtime of the file and don't fail.
1584 Fixes Savannah bug #13280.
1586 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1587 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1588 inside a variable reference. Make this function static as it's
1590 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1591 parsing an unexpanded line looking for semicolons.
1592 Fixes Savannah bug #1454.
1593 * misc.c (remove_comments): Move this to read.c and make it static
1594 as it's only used there. Call find_char_unquote() with new arg.
1595 * make.h: Remove prototypes for find_char_unquote() and
1596 remove_comments() since they're static now.
1598 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1599 its export flag and obtain its value. When we need to re-exec,
1600 increment the value and add it into the environment.
1601 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1602 * NEWS: Mention MAKE_RESTARTS.
1603 * main.c (always_make_set): New variable. Change the -B option to
1604 set this one instead.
1605 (main): When checking makefiles, only set always_make_flag if
1606 always_make_set is set AND the restarts flag is 0. When building
1607 normal targets, set it IFF always_make_set is set.
1608 (main): Avoid infinite recursion with -W, too: only set what-if
1609 files to NEW before we check makefiles if we've never restarted
1610 before. If we have restarted, set what-if files to NEW _after_ we
1612 Fixes Savannah bug #7566:
1614 2005-06-17 Paul D. Smith <psmith@gnu.org>
1616 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1617 in the prerequisites list.
1619 2005-06-12 Paul D. Smith <psmith@gnu.org>
1621 Fix Savannah bug # 1328.
1623 * configure.in: Check for atexit().
1624 * misc.c (close_stdout): Test stdout to see if writes to it have
1625 failed. If so, be sure to exit with a non-0 error code. Based on
1626 code found in gnulib.
1627 * make.h: Prototype.
1628 * main.c (main): Install close_stdout() with atexit().
1630 2005-06-10 Paul D. Smith <psmith@gnu.org>
1632 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1634 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1635 headers; make vmsWaitForChildren() static; extern vmsify().
1636 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1637 Don't create child_execute_job() here (it's in vmsjobs.c).
1638 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1640 2005-06-09 Paul D. Smith <psmith@gnu.org>
1642 * variable.c (push_new_variable_scope): File variables point
1643 directly to the global_setlist variable. So, inserting a new
1644 scope in front of that has no effect on those variables: they
1645 don't go through current_variable_set_list. If we're pushing a
1646 scope and the current scope is global, push it "the other way" so
1647 that the new setlist is in the global_setlist variable, and
1648 next points to a new setlist with the global variable set.
1649 (pop_variable_scope): Properly undo a push with the new
1651 Fixes Savannah bug #11913.
1653 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1655 * job.c (reap_children): Don't die of the command failed but
1656 the dontcare flag is set. Fixes Savannah bug #13216.
1658 * implicit.c (pattern_search): When creating a target from
1659 an implicit rule match, lookup pattern target and set precious
1660 flag in a newly created target. Fixes Savannah bug #13218.
1662 2005-05-13 Paul D. Smith <psmith@gnu.org>
1664 Implement "if... else if... endif" syntax.
1666 * read.c (eval): Push all checks for conditional words ("ifeq",
1667 "else", etc.) down into the conditional_line() function.
1668 (conditional_line): Rework to allow "else if..." clause. New
1669 return value -2 for lines which are not conditionals. The
1670 ignoring flag can now also be 2, which means "already parsed a
1671 true branch". If that value is seen no other branch of this
1672 conditional can be considered true. In the else parsing if there
1673 is extra text after the else, invoke conditional_line()
1674 recursively to see if it's another conditional. If not, it's an
1675 error. If so, raise the conditional value to this level instead
1676 of creating a new conditional nesting level. Special check for
1677 "else" and "endif", which aren't allowed on the "else" line.
1678 * doc/make.texi (Conditional Syntax): Document the new syntax.
1680 2005-05-09 Paul D. Smith <psmith@gnu.org>
1682 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1683 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1684 recurses to the w32 directory, even on non-Windows systems. Use
1685 the method suggested in the automake manual.
1686 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1687 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1689 2005-05-07 Paul D. Smith <psmith@gnu.org>
1691 * main.c (die): If we're dying with a fatal error (not that a
1692 command has failed), write back any leftover tokens before we go.
1694 * job.c (set_child_handler_action_flags): If there are jobs
1695 waiting for the load to go down, set an alarm to go off in 1
1696 second. This allows us to wake up from a potentially long-lasting
1697 read() and start a new job if the load has gone down. Turn it off
1699 (job_noop): Dummy signal handler function.
1700 (new_job): Invoke it with the new semantics.
1702 * docs/make.texi: Document secondary expansion. Various cleanups
1705 2005-05-03 Paul D. Smith <psmith@gnu.org>
1707 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1708 the targets which are to ultimately be made are called "goals";
1709 see the GNU make manual. Also, MAKECMDGOALS, etc.
1711 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1712 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1713 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1715 2005-05-02 Paul D. Smith <psmith@gnu.org>
1717 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1718 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1719 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1720 functions to vmsjobs.c. #include it into jobs.c.
1722 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1723 jobserver tokens. I found that this happens when an exported
1724 recursive variable contains a $(shell ...) function reference: in
1725 this situation we could "forget" to write back a token.
1727 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1728 we have. It's not reliable to depend on the number of children in
1729 our linked list so keep a separate count.
1730 (new_job): Check jobserver_tokens rather than children &&
1731 waiting_jobs. Increment jobserver_tokens when we get one.
1732 (free_child): If jobserver_tokens is 0, internal error. If it's
1733 >1, write a token back to the jobserver pipe (we don't write a
1734 token for the "free" job). Decrement jobserver_tokens.
1736 * main.c: Add variable master_job_slots.
1737 (main): Set it to hold the number of jobs requested if we're the
1738 master process, when using the jobserver.
1739 (die): Sanity checks: first test jobserver_tokens to make sure
1740 this process isn't holding any tokens we didn't write back.
1741 Second, if master_job_slots is set count the tokens left in the
1742 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1744 2005-04-24 Paul D. Smith <psmith@gnu.org>
1746 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1747 with -l# can lose jobserver tokens, because waiting jobs are not
1748 consulted properly when checking for the "free" token.
1750 * job.c (free_child): Count waiting_jobs as having tokens.
1751 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1752 handle jobs waiting for the load to drop.
1754 2005-04-23 Paul D. Smith <psmith@gnu.org>
1756 * main.c (main): Be careful to not core if a variable setting in
1757 the environment doesn't contain an '='. This is illegal but can
1758 happen in broken setups.
1759 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1761 2005-04-12 Paul D. Smith <psmith@gnu.org>
1763 The second expansion feature causes significant slowdown. Timing
1764 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1765 read the makefile before the feature, to 11+s to do the same
1766 operations after the feature. Additionally, memory usage
1767 increased drastically. To fix this I added some intelligence that
1768 avoids the overhead of the second expansion unless it's required.
1770 * dep.h: Add a new boolean field, need_2nd_expansion.
1772 * read.c (eval): When creating the struct dep for the target,
1773 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1774 (record_files): If there's a "%" in a static pattern rule, it gets
1775 converted to "$*" so set need_2nd_expansion to 1.
1777 * file.c (expand_deps): Rework to be more efficient. Only perform
1778 initialize_file_variables(), set_file_variables(), and
1779 variable_expand_for_file() if the need_2nd_expansion is set.
1781 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1782 (pattern_search): Ditto.
1783 * main.c (handle_non_switch_argument): Ditto.
1785 * read.c (read_all_makefiles): Ditto.
1786 (eval_makefile): Ditto.
1788 2005-04-07 Paul D. Smith <psmith@gnu.org>
1790 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1791 * variable.c (sync_Path_environment): Ditto.
1792 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1794 * main.c (main): Define the .FEATURES variable.
1795 * NEWS: Announce .FEATURES.
1796 * doc/make.texi (Special Variables): Document .FEATURES.
1798 * remake.c (check_dep): If a file is .PHONY, update it even if
1799 it's marked intermediate. Fixes Savannah bug #12331.
1801 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1803 * file.c (expand_deps): Factor out the second expansion and
1804 prerequisite line parsing logic from snap_deps().
1806 * file.c (snap_deps): Use expand_deps(). Expand and parse
1807 prerequisites of the .SUFFIXES special target first. Fixes
1808 Savannah bug #12320.
1810 2005-03-13 Paul D. Smith <psmith@gnu.org>
1812 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1815 2005-03-11 Paul D. Smith <psmith@gnu.org>
1817 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1818 available, not undefined (from Earnie Boyd).
1820 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1822 * implicit.c (pattern_search): Mark an intermediate target as
1823 precious if it happened to be a prerequisite of some (other)
1824 target. Fixes Savannah bug #12267.
1826 2005-03-09 Paul D. Smith <psmith@gnu.org>
1828 * read.c (eval_makefile): Add alloca(0).
1829 (eval_buffer): Ditto.
1831 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1833 * main.c (main): Use o_file instead of o_default when defining
1834 the .DEFAULT_TARGET special variable.
1835 * read.c (eval): Use define_variable_global() instead of
1836 define_variable() when setting new value for the .DEFAULT_TARGET
1837 special variable. Fixes Savannah bug #12266.
1839 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1841 * imlicit.c (pattern_search): Mark files for which an implicit
1842 rule has been found as targets. Fixes Savannah bug #12202.
1844 2005-03-04 Paul D. Smith <psmith@gnu.org>
1847 * doc/make.texi (Automatic Variables): Document $|.
1849 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1851 * read.c (record_files): Instead of substituting % with
1852 actual stem value in dependency list replace it with $*.
1853 This fixes stem triple expansion bug.
1855 * implicit.c (pattern_search): Copy stem to a separate
1856 buffer and make it a properly terminated string. Assign
1857 this buffer instead of STEM (which is not terminated) to
1858 f->stem. Instead of substituting % with actual stem value
1859 in dependency list replace it with $*. This fixes stem
1860 triple expansion bug.
1862 2005-03-01 Paul D. Smith <psmith@gnu.org>
1864 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1865 on Windows, as it takes a handle not a pid. Just exit.
1866 Fix from patch #3679, provided by Alessandro Vesely.
1868 * configure.in: Update check for sys_siglist[] from autoconf manual.
1869 * signame.c (strsignal): Update to use the new autoconf macro.
1871 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1873 * read.c (record_files): Add a check for the list of prerequisites
1874 of a static pattern rule being empty. Fixes Savannah bug #12180.
1876 2005-02-28 Paul D. Smith <psmith@gnu.org>
1878 * doc/make.texi (Text Functions): Update docs to allow the end
1879 ordinal for $(wordlist ...) to be 0.
1880 * function.c (func_wordlist): Fail if the start ordinal for
1881 $(wordlist ...) is <1. Matches documentation.
1882 Resolves Savannah support request #103195.
1884 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1885 previously we were stopping when !-q, exactly the opposite. This
1886 has been wrong since version 1.34, in 1994!
1887 (update_file): If we got an error don't break out to run more
1888 double-colon rules: just return immediately.
1889 Fixes Savannah bug #7144.
1891 2005-02-27 Paul D. Smith <psmith@gnu.org>
1893 * misc.c (end_of_token): Make argument const.
1894 * make.h: Update prototype.
1896 * function.c (abspath, func_realpath, func_abspath): Use
1897 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1898 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1899 * read.c (record_files): Ditto.
1900 * variable.c (do_variable_definition): Ditto.
1902 * function.c (func_error): Create a new function $(info ...) that
1903 simply prints the message to stdout with no extras.
1904 (function_table_init): Add new function to the table.
1905 * NEWS: Add $(info ...) reference.
1906 * doc/make.texi (Make Control Functions): Document it.
1908 New feature: if the system supports symbolic links, and the user
1909 provides the -L/--check-symlink-time flag, then use the latest
1910 mtime between the symlink(s) and the target file.
1912 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1913 readlink(). If both are available, define MAKE_SYMLINKS.
1914 * main.c: New variable: check_symlink_flag.
1915 (usage): Add a line for -L/--check-symlink-times to the help string.
1916 (switches): Add -L/--check-symlink-times command line argument.
1917 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1918 print a warning and disable it again.
1919 * make.h: Declare check_symlink_flag.
1920 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1921 if the file is a symlink then check each link in the chain and
1922 choose the NEWEST mtime we find as the mtime for the file. The
1923 newest mtime might be the file itself!
1924 * NEWS: Add information about this new feature.
1925 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1927 Avoid core dumps described in Savannah bug # 12124:
1929 * file.c: New variable snapped_deps remember whether we've run
1931 (snap_deps): Set it.
1932 * filedef.h: Extern it.
1933 * read.c (record_files): Check snapped_deps; if it's set then
1934 we're trying to eval a new target/prerequisite relationship from
1935 within a command script, which we don't support. Fatal.
1937 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1939 Implementation of the .DEFAULT_TARGET special variable.
1941 * read.c (eval): If necessary, update default_target_name when
1943 * read.c (record_files): Update default_target_file if
1944 default_target_name has changed.
1945 * main.c (default_target_name): Define.
1946 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1947 default_target_name is set use default_target_file as a root
1949 * filedef.h (default_target_name): Declare.
1950 * dep.h (free_dep_chain):
1951 * misc.c (free_dep_chain): Change to operate on struct nameseq
1952 and change name to free_ns_chain.
1953 * file.c (snap_deps): Update to use free_ns_chain.
1955 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1957 Implementation of the second expansion in explicit rules,
1958 static pattern rules and implicit rules.
1960 * read.c (eval): Refrain from chopping up rule's dependencies.
1961 Store them in a struct dep as a single dependency line. Remove
1962 the code that implements SySV-style automatic variables.
1964 * read.c (record_files): Adjust the code that handles static
1965 pattern rules to expand all percents instead of only the first
1966 one. Reverse the order in which dependencies are stored so that
1967 when the second expansion reverses them again they appear in
1968 the makefile order (with some exceptions, see comments in
1969 the code). Remove the code that implements SySV-style automatic
1972 * file.c (snap_deps): Implement the second expansion and chopping
1973 of dependency lines for explicit rules.
1975 * implicit.c (struct idep): Define an auxiliary data type to hold
1976 implicit rule's dependencies after stem substitution and
1979 * implicit.c (free_idep_chain): Implement.
1981 * implicit.c (get_next_word): Implement helper function for
1982 parsing implicit rule's dependency lines into words taking
1983 into account variable expansion requests. Used in the stem
1986 * implicit.c (pattern_search): Implement the second expansion
1987 for implicit rules. Also fixes bug #12091.
1989 * commands.h (set_file_variables): Declare.
1990 * commands.c (set_file_variables): Remove static specifier.
1992 * dep.h (free_dep_chain): Declare.
1993 * misc.c (free_dep_chain): Implement.
1995 * variable.h (variable_expand_for_file): Declare.
1996 * expand.c (variable_expand_for_file): Remove static specifier.
1998 * make.h (strip_whitespace): Declare.
1999 * function.c (strip_whitespace): Remove static specifier.
2001 2005-02-26 Paul D. Smith <psmith@gnu.org>
2003 * main.c (main): Check for ferror() when reading makefiles from stdin.
2004 Apparently some shells in Windows don't close pipes properly and
2007 2005-02-24 Jonathan Grant <jg@jguk.org>
2009 * configure.in: Add MinGW configuration options, and extra w32 code
2011 * Makefile.am: Add MinGW configuration options, and extra w32 code
2013 * main.c: Determine correct program string (after last \ without .exe).
2014 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2016 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2017 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2018 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2019 environment support.
2021 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2023 * function.c (func_shell): When initializing error_prefix, check
2024 that reading file name is not null. This fixes long-standing
2025 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2027 2005-02-09 Paul D. Smith <psmith@gnu.org>
2029 * maintMakefile: Update the CVS download URL to simplify them.
2030 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2031 downloading the .texi files from Savannah now.
2033 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2035 * main.c (handle_non_switch_argument): Only add variables to
2036 command_variables if they're not already there: duplicate settings
2037 waste space and can be confusing to read.
2039 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2040 this header is never included by non-WINDOWS32 code, and it
2041 requires <config.h> to define which isn't always included first.
2043 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2044 testing MINGW32 versions.
2046 * main.c (log_working_directory): flush stdout to be sure the WD
2047 change is printed before any stderr messages show up.
2049 2005-02-01 Paul D. Smith <psmith@gnu.org>
2051 * maintMakefile (po_repo): Update the GNU translation site URL.
2053 2004-12-01 Paul D. Smith <psmith@gnu.org>
2055 * main.c (main): Change char* env_shell to struct variable shell_var.
2056 * variable.c (target_environment): Use new shell_var.
2058 2004-11-30 Paul D. Smith <psmith@gnu.org>
2060 * configure.in: The old way we avoided creating build.sh from
2061 build.sh.in before build.sh.in exists doesn't work anymore; we
2062 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2063 the help!). This also keeps automake from complaining.
2064 * Makefile.am (README): Add a dummy target so automake won't
2065 complain that this file doesn't exist when we checkout from CVS.
2066 * maintMakefile (.dep_segment): Rewrite this rule since newer
2067 versions of automake don't provide DEP_FILES.
2069 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2071 Implementation of `realpath' and `abspath' built-in functions.
2073 * configure.in: Check for realpath.
2074 * function.c (abspath): Return an absolute file name that does
2075 not contain any `.' or `..' components, nor repeated `/'.
2076 * function.c (func_abspath): For each name call abspath.
2077 * function.c (func_realpath): For each name call realpath
2078 from libc or delegate to abspath if realpath is not available.
2079 * doc/make.texi (Functions for File Names): Document new functions.
2080 * doc/make.texi (Quick Reference): Ditto.
2082 2004-11-28 Paul D. Smith <psmith@gnu.org>
2084 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2085 arguments. Fixes bug #10252.
2087 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2089 * main.c (main): Set SHELL to v_noexport by default. Remember the
2090 original environment setting of SHELL in the env_shell variable.
2091 * main.h: Export new env_shell variable.
2092 * variable.c (target_environment): If we find a v_noexport
2093 variable for SHELL, add a SHELL variable with the env_shell value.
2094 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2095 * doc/make.texi (Variables/Recursion): Ditto.
2097 2004-11-28 Paul D. Smith <psmith@gnu.org>
2099 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2100 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2101 Patch by Alessandro Vesely.
2103 2004-11-12 Paul D. Smith <psmith@gnu.org>
2105 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2106 the command line if it's inside a string.
2107 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2109 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2111 * function.c (func_lastword): New function: return last word
2112 from the list of words.
2113 * doc/make.texi: Document $(lastword ). Fix broken links in
2114 Quick Reference section.
2116 2004-10-06 Paul D. Smith <psmith@gnu.org>
2118 Apply patch from Alessandro Vesely, provided with bug # 9748.
2119 Fix use of tmpnam() to work with Borland C.
2121 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2122 construction of a temporary filename, and call new function
2123 create_batch_filename().
2124 (create_batch_filename) [WINDOWS32]: New function to create a
2127 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2129 * read.c (record_target_var): Expand simple pattern-specific
2131 * variable.c (initialize_file_variables): Do not expand simple
2132 pattern-specific variable.
2134 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2136 * remake.c (update_file_1): When rebuilding makefiles inherit
2137 dontcare flag from a target that triggered update.
2139 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2141 * variable.c (initialize_file_variables): Mark pattern-specific
2142 variable as a per-target and copy export status.
2144 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2146 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2148 * implicit.c (pattern_search): When considering an implicit rule's
2149 prerequisite check that it is actually a target rather then
2150 just an entry in the file hashtable.
2152 2004-09-21 Paul D. Smith <psmith@gnu.org>
2154 * read.c (readstring): Fix some logic errors in backslash handling.
2155 (eval): Remove some unnecessary processing in buffer handling.
2156 (record_target_var): Assert that parse_variable_definition() succeeded.
2157 Reported by: Markus Mauhart <qwe123@chello.at>.
2159 * misc.c: Removed the sindex() function. All instances of this
2160 function were trivially replaceable by the standard strstr()
2161 function, and that function will always have better (or certainly
2162 no worse) performance than the very simple-minded algorithm
2163 sindex() used. This can matter with complex makefiles.
2164 * make.h: Remove the prototype for sindex().
2165 * function.c (subst_expand): Convert sindex() call to strstr().
2166 This means we no longer need to track the TLEN value so remove that.
2167 (func_findstring): Convert sindex() to strstr().
2168 * commands.c (chop_commands): Convert sindex() calls to strstr().
2169 Suggested by: Markus Mauhart <qwe123@chello.at>.
2171 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2172 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2173 If SHELL is set to CMD.EXE then assume it's batch-mode and
2174 non-unixy. I wrote the code differently from the patch, though,
2175 to make it safer. This also resolves bug #9174.
2177 2004-09-20 Paul D. Smith <psmith@gnu.org>
2179 * expand.c (variable_expand_string): Modify to invoke
2180 patsubst_expand() instead of subst_expand(); the latter didn't
2181 handle suffix patterns correctly.
2182 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2183 was used only from variable_expand_string() and is no longer used
2185 (func_subst): Ditto, on call to subst_expand().
2186 (patsubst_expand): Require the percent pointers to point to the
2187 character after the %, not to the % itself.
2188 * read.c (record_files): New call criteria for patsubst_expand().
2189 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2190 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2192 2004-09-19 Paul D. Smith <psmith@gnu.org>
2194 * function.c (subst_expand): Fix a check in by_word: look for a
2195 previous blank if we're beyond the beginning of the string, not
2196 the beginning of the word.
2197 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2199 2004-05-16 Paul D. Smith <psmith@gnu.org>
2201 * remake.c (update_goal_chain): Change the argument specifying
2202 whether we're rebuilding makefiles to be a global variable,
2203 REBUILDING_MAKEFILES.
2204 (complain): Extract the code that complains about no rules to make
2205 a target into a separate function.
2206 (update_file_1): If we tried to rebuild a file during the makefile
2207 rebuild phase and it was dontcare, then no message was printed.
2208 If we then try to build the same file during the normal build,
2209 print a message this time.
2210 (remake_file): Don't complain about un-remake-able files when
2211 we're rebuilding makefiles.
2213 2004-05-11 Paul D. Smith <psmith@gnu.org>
2215 * job.c (construct_command_argv_internal): OS/2 patches from
2216 Andreas Buening <andreas.buening@nexgo.de>.
2218 2004-05-10 Paul D. Smith <psmith@gnu.org>
2220 * remake.c (update_file): Don't walk the double-colon chain unless
2221 this is a double-colon rule. Fix suggested by Boris Kolpackov
2222 <boris@kolpackov.net>.
2224 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2225 * readme.vms: New section describing OpenVMS support and issues.
2226 * default.c (default_variables): Add support for IA64.
2227 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2228 without some privilege aborts make with the error
2229 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2230 pressing Ctrl+Y and the input device is no terminal. The change
2231 catches this error and just continues.
2233 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2235 2004-04-25 Paul D. Smith <psmith@gnu.org>
2237 * commands.c (set_file_variables): Set $< properly in the face of
2238 order-only prerequisites.
2239 Patch from Boris Kolpackov <boris@kolpackov.net>
2241 2004-04-21 Bob Byrnes <byrnes@curl.com>
2243 * main.c (main): Notice failures to remake makefiles.
2245 2004-03-28 Paul D. Smith <psmith@gnu.org>
2247 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2249 * job.c: No default shell for RISC OS.
2250 (load_too_high): Hard-code the return to 1.
2251 (construct_command_argv_internal): No sh_chars or sh_cmds.
2252 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2254 2004-03-20 Paul D. Smith <psmith@gnu.org>
2256 * variable.c (do_variable_definition): Don't append from the
2257 global set if a previous non-appending target-specific variable
2258 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2261 * expand.c (reference_variable): Don't give up on variables with
2262 no value that have the target-specific append flag set: they might
2263 have a value after all. Reported by Oliver Schmidt
2264 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2265 <nikulin@dx1cmd.inp.nsk.su>.
2267 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2268 refer to absolute pathnames in directories that don't exist: some
2269 portion of the makefile could create those directories before we
2270 match the pattern. Fixes bugs #775 and #108.
2272 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2274 * main.c (main): Free makefile_mtimes if we have any.
2275 * README.W32.template: Update documentation for the current status
2276 of the MS-Windows port.
2277 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2278 environment variable is sometimes already defined which causes the
2280 * main.c (debug_signal_handler): Only define this function if
2281 SIGUSR1 is available.
2283 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2285 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2286 * README.OS2.template: Documentation updates.
2287 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2288 link line for safety.
2289 * maintMakefile (build.sh.in): Remove an extraneous ")".
2290 * job.c (child_execute_job): Close saved FDs.
2291 * job.c (exec_command) [OS/2]: exec_command(): If the command
2292 can't be exec'ed and if the shell is not Unix-sh, then try again
2293 with argv = { "cmd", "/c", ... }. Normally, this code is never
2294 reached for the cmd shell unless the command really doesn't exist.
2295 (construct_command_argv_internal) [OS/2]: The code for cmd
2296 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2297 The CMD builtin commands are case insensitive so use strcasecmp().
2299 2004-03-19 Paul D. Smith <psmith@gnu.org>
2301 * read.c (do_define): Re-order line counter increment so the count
2302 is accurate (we were losing one line per define). Reported by
2303 Dave Yost <Dave@Yost.com>.
2305 2004-03-06 Paul D. Smith <psmith@gnu.org>
2307 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2309 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2310 * misc.c (message,error,fatal): Ditto.
2311 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2312 * config.h.W32.template: Ditto.
2313 * config.h-vms.template: Ditto.
2314 * config.ami.template: Ditto.
2316 2004-03-04 Paul D. Smith <psmith@gnu.org>
2318 * README.template: Add a note about broken /bin/sh on SunOS
2319 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2321 * misc.c (message, error, fatal): Don't use "..." if we're using
2322 varargs. ansi2knr should handle this but it doesn't work: it
2323 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2324 done. On many systems (SunOS for example) va_dcl is a #define.
2325 So, force the use of the non-"..." version on pre-ANSI compilers.
2327 * maintMakefile (sign-dist): Create some rules to help automate
2328 the new GNU ftp upload method.
2330 2004-02-24 Paul D. Smith <psmith@gnu.org>
2332 * config.h.W32.template: Add HAVE_STDARG_H
2333 * config.h-vms.template: Ditto.
2334 * config.ami.template: Ditto.
2336 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2338 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2339 * build_w32.bat: Remove extra "+".
2341 2004-02-23 Paul D. Smith <psmith@gnu.org>
2343 * make.h: Create an UNUSED macro to mark unused parameters.
2344 * (many): Clean up warnings by applying UNUSED, fixing
2345 signed/unsigned incompatibilities, etc.
2347 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2349 * filedef.h: Name the command_state enumeration.
2350 * file.c (set_command_state): Use the enumeration in the function
2353 * configure.in: Explicitly set SET_MAKE to empty, to disable
2354 MAKE=make even when no make already exists. Fix bug #3823.
2356 2004-02-22 Paul D. Smith <psmith@gnu.org>
2358 * maintMakefile: Perl script to clean up all non-CVS files. Use
2359 it on all the subdirectories for the cvs-clean target.
2361 * main.c (decode_switches): Require non-empty strings for all our
2362 string command-line options. Fixes Debian bug # 164165.
2364 * configure.in: Check for stdarg.h and varargs.h.
2365 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2366 for printing messages.
2367 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2372 A number of patches for OS/2 support from Andreas Buening
2373 <andreas.buening@nexgo.de>:
2375 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2376 disable the SIGCHLD handler.
2377 (reap_children) [OS/2]: Remove special handling of job_rfd.
2378 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2379 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2380 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2381 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2382 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2385 2004-02-21 Paul D. Smith <psmith@gnu.org>
2387 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2388 <mail@kristov.de> reports that if process_begin() fails we don't
2389 handle the error condition correctly in all cases.
2390 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2391 to have a newline on the message.
2393 * job.c (construct_command_argv_internal): Add "test" to UNIX
2394 sh_cmds[]. Fixes Savannah bug # 7606.
2396 2004-02-04 Paul D. Smith <psmith@gnu.org>
2398 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2399 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2400 Hartmut Becker <Hartmut.Becker@hp.com>.
2402 2004-01-21 Paul D. Smith <psmith@gnu.org>
2404 * job.c (load_too_high): Implement an algorithm to control the
2405 "thundering herd" problem when using -l to control job creation
2406 via the load average. The system only recomputes the load once a
2407 second but we can start many jobs in a second. To solve this we
2408 keep track of the number of jobs started in the last second and
2409 apply a weight to try to guess what a correct load would be.
2410 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2411 Also fixes bug #4693.
2412 (reap_children): Decrease the job count for this second.
2413 (start_job_command): Increase the job count for this second.
2415 * read.c (conditional_line): Expand the text after ifn?def before
2416 checking to see if it's a single word. Fixes bug #7257.
2418 2004-01-09 Paul D. Smith <psmith@gnu.org>
2420 * file.c (print_file): Recurse to print all targets in
2421 double-colon rules. Fixes bug #4518, reported (with patch) by
2422 Andrew Chatham <chatham@google.com>.
2424 2004-01-07 Paul D. Smith <psmith@gnu.org>
2426 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2427 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2428 AC_FUNC_SETVBUF_REVERSED.
2430 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2431 (MAKE Variable): Fix Savannah bug #4898.
2433 * job.c (construct_command_argv_internal): Add "!" to the list of
2434 shell escape chars. POSIX sh allows it to appear before a
2435 command, to negate the exit code. Fixes bug #6404.
2437 * implicit.c (pattern_search): When matching an implicit rule,
2438 remember which dependencies have the ignore_mtime flag set.
2439 Original fix provided in Savannah patch #2349, by Benoit
2440 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2442 2003-11-22 Paul D. Smith <psmith@gnu.org>
2444 * README.W32.template (Outputs): Clarification on -j with
2445 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2448 2003-11-02 Paul D. Smith <psmith@gnu.org>
2450 * function.c (func_if): Strip all the trailing whitespace from the
2451 condition, then don't expand it. Fixed bug # 5798.
2453 * expand.c (recursively_expand_for_file): If we're expanding a
2454 variable with no file context, then use the variable's context.
2457 2003-10-21 Paul D. Smith <psmith@gnu.org>
2459 * main.c (log_working_directory): Add newlines to printf()s.
2461 * README.cvs: Add a note to ignore warnings during autoreconf.
2463 * maintMakefile (po_repo): Set a new URL for PO file updates.
2464 (get-config/config.guess get-config/config.sub): Get these files
2465 from the Savannah config project instead of ftp.gnu.org.
2467 2003-10-05 Paul Eggert <eggert@twinsun.com>
2469 * main.c (main): Avoid potential subscript error if environ has
2472 2003-08-22 Paul D. Smith <psmith@gnu.org>
2474 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2475 systems which don't yet implement the C89 standard :-/.
2477 2003-07-18 Paul D. Smith <psmith@gnu.org>
2479 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2480 [WINDOWS32]: Initialize hash.
2482 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2484 * dir.c (read_dirstream): Provide a workaround for broken versions of
2485 the MinGW dirent structure.
2487 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2489 * w32/include/dirent.h: Add __MINGW32__ filter.
2491 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2493 * make.h: Add global declaration of *make_host.
2494 * main.c (print_usage): Remove local declaration of *make_host.
2495 (print_version): Display "This program built for ..." after Copyright
2498 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2500 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2501 execution of "makeinfo --html make.texi".
2503 2003-04-30 Paul D. Smith <psmith@gnu.org>
2505 * build.template: Make some changes to maybe allow this script to
2506 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2508 * README.OS2.template: New file for OS/2 support. Original
2509 contributed by Andreas Buening.
2510 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2513 2003-04-19 Paul D. Smith <psmith@gnu.org>
2515 Fix bug #1405: allow a target to match multiple pattern-specific
2518 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2519 variable.c, where they've always belonged.
2520 * rule.h: Move the prototypes and struct pattern_var as well.
2521 * variable.c (initialize_file_variables): Invoke
2522 lookup_pattern_var() in a loop, until no more matches are found.
2523 If a match is found, create a new variable set for the target's
2524 pattern variables. Then merge the contents of each matching
2525 pattern variable set into the target's pattern variable set.
2526 (lookup_pattern_var): Change this function to be usable
2527 in a loop. It takes a starting position: if NULL, start at the
2528 beginning; if non-NULL, start with the pattern variable after that
2529 position, and return the next matching pattern.
2530 (create_pattern_var): Create a unique instance of
2531 pattern-specific variables for every definition in the makefile.
2532 Don't combine the same pattern together. This allows us to
2533 process the variable handling properly even when the same pattern
2534 is used multiple times.
2535 (parse_variable_definition): New function: break out the parsing
2536 of a variable definition line from try_variable_definition.
2537 (try_variable_definition): Call parse_variable_definition to
2539 (print_variable_data_base): Print out pattern-specific variables.
2540 * variable.h (struct variable): Remember when a variable is
2541 conditional. Also remember its flavor.
2542 (struct pattern_var): Instead of keeping a variable set, we just
2543 keep a single variable for each pattern.
2544 * read.c (record_target_var): Each pattern variable contains only a
2545 single variable, not a set, so create it properly.
2546 * doc/make.texi (Pattern-specific): Document the new behavior.
2548 2003-04-17 Paul D. Smith <psmith@gnu.org>
2550 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2551 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2552 file/directory naming rules for VMS so I can't tell whether this
2555 2003-04-09 Paul D. Smith <psmith@gnu.org>
2557 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2558 DOS-style pathnames: backslash separators and drive specifiers.
2560 2003-03-28 Paul D. Smith <psmith@gnu.org>
2562 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2563 the intermediate flag on all targets. Fixes bug #2515.
2565 2003-03-24 Paul D. Smith <psmith@gnu.org>
2567 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2568 Upgrade to autoconf 2.57 and automake 1.7.3.
2570 * job.c: More OS/2 changes from Andreas Buening.
2572 * file.c (print_file): Fix variable initialization.
2575 * remake.c (notice_finished_file):
2577 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2578 some calls (like readdir()) return NULL in valid situations
2579 without resetting errno. Fixes bug #2846.
2581 2003-02-25 Paul D. Smith <psmith@gnu.org>
2583 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2585 * job.c (_is_unixy_shell) [OS/2]: New function.
2586 Set default shell to /bin/sh.
2587 (reap_children): Close the job_rfd pipe here since we don't use a
2589 (set_child_handler_action_flags): define this to empty on OS/2.
2590 (start_job_command): Close the jobserver pipe and use
2591 child_execute_job() instead of fork/exec.
2592 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2593 rather than exec'ing, then reconfigure stdin/stdout.
2594 (exec_command): Rewrite to use spawn instead of exec. Return the
2597 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2598 in DOS. Handle the TEMP environment variable as in DOS. Don't
2599 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2600 use -j in DOS mode. Use child_execute_job() instead of
2603 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2606 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2607 prototypes that return values.
2609 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2611 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2612 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2614 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2617 2003-02-24 Paul D. Smith <psmith@gnu.org>
2619 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2620 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2621 (child_execute_job) [VMS]: Handle error status properly.
2622 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2624 * function.c (func_shell): Use EINTRLOOP() while reading from the
2625 subshell pipe (Fixes bug #2502).
2626 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2628 * main.c (main): Ditto.
2630 2003-01-30 Paul D. Smith <psmith@gnu.org>
2632 * read.c (eval): eval() was not fully reentrant, because the
2633 collapsed buffer was static. Change it to be an automatic
2634 variable so that eval() can be invoked recursively.
2636 (eval): Apply patch # 1022: fix memory reference error on long
2637 target-specific variable lines.
2638 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2640 * function.c (check_numeric): Combine the is_numeric() function
2641 into this function, since it's only called from one place.
2642 Constify this function. Have it print the incorrect string in the
2643 error message. Fixes bug #2407.
2644 (strip_whitespace): Constify.
2645 (func_if): Constify.
2646 * expand.c (expand_argument): Constify.
2648 2003-01-29 Paul D. Smith <psmith@gnu.org>
2650 Fix bug # 2169, also reported by other people on various systems.
2652 * make.h: Some systems, such as Solaris and PTX, do not fully
2653 implement POSIX-compliant SA_RESTART functionality; important
2654 system calls like stat() and readdir() can still fail with EINTR
2655 even if SA_RESTART has been set on the signal handler. So,
2656 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2657 EINTR for system calls which return -1 or 0 (NULL), respectively,
2659 Also, remove the old atomic_stat()/atomic_readdir() and
2660 HAVE_BROKEN_RESTART handling.
2662 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2664 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2665 * remake.c (touch_file): Ditto.
2667 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2668 * read.c (construct_include_path): Ditto.
2669 * remake.c (name_mtime): Ditto.
2670 * vpath.c (selective_vpath_search): Ditto.
2671 * dir.c (find_directory): Ditto.
2672 (local_stat): Ditto.
2673 (find_directory): Use ENULLLOOP() to wrap opendir().
2674 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2676 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2677 atomic_readdir() handling.
2679 2003-01-22 Paul D. Smith <psmith@gnu.org>
2681 * function.c (func_call): Fix Bug #1744. If we're inside a
2682 recursive invocation of $(call ...), mask any of the outer
2683 invocation's arguments that aren't used by this one, so that this
2684 invocation doesn't "inherit" them accidentally.
2686 2002-12-05 Paul D. Smith <psmith@gnu.org>
2688 * function.c (subst_expand): Valery Khamenia reported a
2689 pathological performance hit when doing substitutions on very
2690 large values with lots of words: turns out we were invoking
2691 strlen() a ridiculous number of times. Instead of having each
2692 call to sindex() call strlen() again, keep track of how much of
2693 the text we've seen and pass the length to sindex().
2695 2002-11-19 Paul D. Smith <psmith@gnu.org>
2697 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2700 2002-11-16 Paul D. Smith <psmith@gnu.org>
2702 * NMakefile.template (OBJS): Add hash.c object file.
2703 * SMakefile.template (srcs): Ditto.
2704 * Makefile.ami (objs): Ditto.
2705 * build_w32.bat: Ditto.
2707 * Makefile.DOS.template: Remove extra dependencies.
2709 2002-10-25 Paul D. Smith <psmith@gnu.org>
2711 * expand.c (install_variable_buffer): New function. Install a new
2712 variable_buffer context and return the previous one.
2713 (restore_variable_buffer): New function. Free the current
2714 variable_buffer context and put a previously saved one back.
2715 * variable.h: Prototypes for {install,restore}_variable_buffer.
2716 * function.c (func_eval): Push a new variable_buffer context
2717 before we eval, then restore the old one when we're done.
2720 * read.c (install_conditionals): New function. Install a new
2721 conditional context and return the previous one.
2722 (restore_conditionals): New function. Free the current
2723 conditional context and put a previously saved one back.
2724 (eval): Use the {install,restore}_conditionals for "include"
2726 (eval_buffer): Use {install,restore}_conditionals to preserve the
2727 present conditional state before we evaluate the buffer.
2730 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2732 (Recursion): Add a variable index entry for CURDIR.
2734 * README.cvs: Update to appropriate versions.
2735 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2736 don't need to copy loadavg.c: automake is smart enough to create
2737 it for me. Still have a bug in automake related to ansi2knr tho.
2739 2002-10-14 Paul D. Smith <psmith@gnu.org>
2741 * remake.c (notice_finished_file): Only touch targets if they have
2742 at least one command (as per POSIX). Resolve Bug #1418.
2744 * *.c: Convert to using ANSI C-style function definitions.
2745 * Makefile.am: Enable the ansi2knr feature of automake.
2746 * configure.in: ditto.
2748 2002-10-13 Paul D. Smith <psmith@gnu.org>
2750 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2751 for automatic variable values like $^, etc. In the case of very
2752 large lists of prerequisites this causes problems. Instead reuse
2753 a static buffer (resizeable) for each variable.
2755 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2756 target-specific variable definitions. Check for it and set an
2758 (record_target_var): Set the export field to v_export if the
2759 "exported" flag is set.
2760 * doc/make.texi (Target-specific): Document the ability to use
2763 * doc/make.texi: Change the name of the section on automatic
2764 variables from "Automatic" to "Automatic Variables". Added text
2765 clarifying the scope of automatic variables.
2767 2002-10-04 Paul D. Smith <psmith@gnu.org>
2769 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2771 (record_files): Ditto.
2773 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2774 the search for the '=' to only within the enclosing parens.
2776 2002-10-03 Paul D. Smith <psmith@gnu.org>
2778 Version 3.80 released.
2780 * dir.c: Change hash functions to use K&R function definition style.
2781 * function.c: Ditto.
2783 * variable.c: Ditto.
2785 Update to automake 1.7.
2787 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2788 (pdf): Remove this target as automake now provides one.
2790 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2792 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2794 * makefile.com: Updates for GNU make 3.80.
2795 * makefile.vms: Ditto.
2797 2002-09-23 Paul D. Smith <psmith@gnu.org>
2799 * read.c (enum make_word_type): Remove w_comment.
2800 (get_next_mword): Don't treat comment characters as special; where
2801 this function is used we will never see a comment (it's stripped
2802 before we get here) and treating comments specially means that
2803 targets like "foo\#bar" aren't handled properly.
2805 2002-09-18 Paul D. Smith <psmith@gnu.org>
2807 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2809 * read.c (eval): Expansion of arguments to export/unexport was
2810 ignoring all arguments after the first one. Change the algorithm
2811 to expand the whole line once, then parse the results.
2813 2002-09-17 Paul D. Smith <psmith@gnu.org>
2815 Fix Bug #940 (plus another bug I found while looking at this):
2817 * read.c (record_target_var): enter_file() will add a new entry if
2818 it's a double-colon target: we don't want to do that in this
2819 situation. Invoke lookup_file() and only enter_file() if it does
2820 not already exist. If the file we get back is a double-colon then
2821 add this variable to the "root" double-colon target.
2823 * variable.c (initialize_file_variables): If this file is a
2824 double-colon target but is not the "root" target, then initialize
2825 the root and make the root's variable list the parent of our
2828 2002-09-13 Paul D. Smith <psmith@gnu.org>
2830 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2832 * hash.c (round_up_2): Get rid of a warning.
2834 2002-09-12 Paul D. Smith <psmith@gnu.org>
2836 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2837 so it doesn't complain about getloadavg.c.
2839 * commands.c (set_file_variables): Make sure we always alloca() at
2840 least 1 character for the value of $? (for '\0').
2842 2002-09-11 Paul D. Smith <psmith@gnu.org>
2844 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2845 macro to use RESULT instead of the incorrect _RESULT_.
2847 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2848 and atomic_readdir(). We need to #include dirent.h to get this to
2850 * misc.c (atomic_readdir): Fix typos.
2852 2002-09-10 Paul D. Smith <psmith@gnu.org>
2854 * read.c (eval): Expand variable lists given to export and
2855 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2856 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2858 * doc/make.texi (Variables/Recursion): Document this.
2859 (Conditional Syntax): And here.
2861 2002-09-09 Paul D. Smith <psmith@gnu.org>
2863 * configure.in: Check for memmove().
2865 2002-09-07 Paul D. Smith <psmith@gnu.org>
2867 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2868 Michael Sterrett <msterret@coat.com> reports that while it has
2869 SA_RESTART, it does not work properly.
2871 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2872 that invokes stat() and loops to do it again if it returns EINTR.
2873 (atomic_readdir): Ditto, with readdir().
2875 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2876 and readdir() to atomic_stat() and atomic_readdir().
2878 2002-09-04 Paul D. Smith <psmith@gnu.org>
2880 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2881 reports that GNU make sometimes doesn't recognize that targets can
2882 be made, when directories can be created as prerequisites. He
2883 reports that changing the order of predicates in the DEP->changed
2884 flag test so that lookup_file() is always performed, solves this
2887 2002-08-08 Paul D. Smith <psmith@gnu.org>
2889 * configure.in: Require a newer version of gettext.
2891 * misc.c (perror_with_name): Translate the format string (for
2892 right-to-left language support).
2893 (pfatal_with_name): Ditto.
2895 * main.c: Create a static array of strings to store the usage
2896 text. This is done to facilitate translations.
2897 (struct command_switch): Remove argdesc and description fields.
2898 (switches): Remove values for obsolete fields.
2899 (print_usage): Print each element of the usage array.
2901 * hash.c: Change function definitions to be K&R style.
2903 2002-08-02 Paul D. Smith <psmith@gnu.org>
2905 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2906 this one because it's too hard to get right. We'll look at it for
2908 * main.c (main): Don't create the .TARGETS variable.
2909 * variable.c (handle_special_var): Don't handle .TARGETS.
2911 2002-08-01 Paul D. Smith <psmith@gnu.org>
2913 * main.c (switches): Add a new option, -B (--always-make). If
2914 specified, make will rebuild all targets that it encounters even
2915 if they don't appear to be out of date.
2916 (always_make_flag): New flag.
2917 * make.h: Extern always_make_flag.
2918 * remake.c (update_file_1): Check always_make_flag; if it's set we
2919 will always rebuild any target we can, even if none of its
2920 prerequisites are newer.
2923 * doc/make.texi (Shell Function): Make it clear that make
2924 variables marked as "export" are not passed to instances of the
2927 Add new introspection variable .VARIABLES and .TARGETS.
2929 * variable.c (handle_special_var): New function. If the variable
2930 reference passed in is "special" (.VARIABLES or .TARGETS),
2931 calculate the new value if necessary. .VARIABLES is handled here:
2932 walk through the hash of defined variables and construct a value
2933 which is a list of the names. .TARGETS is handled by
2934 build_target_list().
2935 (lookup_variable): Invoke handle_special_var().
2936 * file.c (build_target_list): Walk through the hask of known files
2937 and construct a list of the names of all the ones marked as
2939 * main.c (main): Initialize them to empty (and as simple variables).
2940 * doc/make.texi (Special Variables): Document them.
2941 * NEWS: Mention them.
2943 * variable.h (struct variable): Add a new flag "exportable" which
2944 is true if the variable name is valid for export.
2945 * variable.c (define_variable_in_set): Set "exportable" when a new
2946 variable is defined.
2947 (target_environment): Use the "exportable" flag instead of
2948 re-checking the name here... an efficiency improvement.
2950 2002-07-31 Paul D. Smith <psmith@gnu.org>
2952 * config.h-vms.template: Updates to build on VMS. Thanks to
2953 Brian_Benning@aksteel.com for helping verify the build.
2954 * makefile.com: Build the new hash.c file.
2955 * hash.h: Use strcpmi(), not stricmp(), in the
2956 HAVE_CASE_INSENSITIVE_FS case.
2958 2002-07-30 Paul D. Smith <psmith@gnu.org>
2960 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2961 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2962 Reported by <Brian_Benning@aksteel.com>.

2966 * variable.c (pop_variable_scope): Remove variable made unused by
2967 new hash infrastructure.
2968 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2969 comparisons as well as name comparisons.

2971 * file.c (lookup_file): Remove variables made unused by new hash
2973 * dir.c (directory_contents_hash_2): Missing return of hash value.
2974 (dir_contents_file_exists_p): Remove variables made unused by new
2975 hash infrastructure.

2979 GNU id-utils package:
2981 2002-07-10 Greg McGary <greg@mcgary.org>
2983 * scripts/functions/filter-out: Add literals to to the
2984 pattern space in order to add complexity, and trigger
2985 use of an internal hash table. Fix documentation strings.
2986 * scripts/targets/INTERMEDIATE: Reverse order of files
2987 passed to expected `rm' command.
2989 2002-07-10 Greg McGary <greg@mcgary.org>

3081 2002-07-10 Paul D. Smith <psmith@gnu.org>
3083 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3084 prerequisite list. A real SysV make will expand the entire
3085 prerequisites list _twice_: we don't do that as it's a big
3086 backward-compatibility problem. We only replace those specific
3089 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3090 references left in the list of prerequisites. Check for .POSIX as
3091 we record targets, so we can disable non-POSIX behavior while
3092 reading makefiles as well as running them.
3093 (eval): Check the prerequisite list to see if we have anything
3094 that looks like a SysV prerequisite variable reference.
3096 2002-07-09 Paul D. Smith <psmith@gnu.org>
3098 * doc/make.texi (Prerequisite Types): Add a new section describing
3099 order-only prerequisites.
3101 * read.c (uniquize_deps): If we have the same file as both a
3102 normal and order-only prereq, get rid of the order-only prereq,
3103 since the normal one supersedes it.
3105 2002-07-08 Paul D. Smith <psmith@gnu.org>
3107 * AUTHORS: Added Greg McGary to the AUTHORS file.
3108 * NEWS: Blurbed order-only prerequisites.
3109 * file.c (print_file): Show order-only deps properly when printing
3112 * maintMakefile: Add "update" targets for wget'ing the latest
3113 versions of various external files. Taken from Makefile.maint in
3116 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.

3119 2002-07-07 Paul D. Smith <psmith@gnu.org>
3121 * po/*.po: Remove. We'll use wget to retrieve them at release
3124 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3125 rather than a shell you get an exception. Make sure we look up
3126 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3128 * remake.c (notice_finished_file): Fix handling of -t flag.
3129 Patch provided by Henning Makholm <henning@makholm.net>.
3131 * implicit.c (pattern_search): Some systems apparently run short
3132 of stack space, and using alloca() in this function caused an
3133 overrun. I modified it to use xmalloc() on the two variables
3134 which seemed like they might get large. Fixes Bug #476.
3136 * main.c (print_version): Update copyright notice to conform with
3138 (print_usage): Update help output.
3140 * function.c (func_eval): Create a new make function, $(eval
3141 ...). Expand the arguments, put them into a buffer, then invoke
3142 eval_buffer() on the resulting string.
3143 (func_quote): Create a new function, $(quote VARNAME). Inserts
3144 the value of the variable VARNAME without expanding it any
3147 * read.c (struct ebuffer): Change the linebuffer structure to an
3148 "eval buffer", which can be either a file or a buffer.
3149 (eval_makefile): Move the code in the old read_makefile() which
3150 located a makefile into here: create a struct ebuffer with that
3151 information. Have it invoke the new function eval() with that
3153 (eval_buffer): Create a new function that creates a struct ebuffer
3154 that holds a string buffer instead of a file. Have it invoke
3155 eval() with that ebuffer.
3156 (eval): New function that contains the guts of the old
3157 read_makefile() function: this function parses makefiles. Obtains
3158 data to parse from the provided ebuffer. Some modifications to
3159 make the flow of the function cleaner and clearer. Still could
3160 use some work here...
3161 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3162 contents of the define/endef variable from the ebuffer.
3163 (readstring): Read the next line from a string-style ebuffer.
3164 (readline): Read the next line from an ebuffer. If it's a string
3165 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3168 * dep.h (eval_buffer): Prototype eval_buffer();
3170 * variable.c (do_variable_definition): Make sure that all
3171 non-target-specific variables are registered in the global set.
3172 If we're invoked from an $(eval ...) we might be inside a $(call
3173 ...) or other function which has pushed a variable scope; we still
3174 want to define our variables from evaluated makefile code in the
3177 2002-07-03 Greg McGary <greg@mcgary.org>
3179 * dep.h (struct dep) [ignore_mtime]: New member.
3180 [changed]: convert to a bitfield.
3181 * implicit.c (pattern_search): Zero ignore_mtime.
3182 * main.c (main, handle_non_switch_argument): Likewise.
3183 * rule.c (convert_suffix_rule): Likewise.
3184 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3185 (read_makefile): Parse '|' in prerequisite list.
3186 (uniquize_deps): Consider ignore_mtime when comparing deps.
3187 * remake.c (update_file_1, check_dep): Don't force remake for
3188 dependencies that have d->ignore_mtime.
3189 * commands.c (FILE_LIST_SEPARATOR): New constant.
3190 (set_file_variables): Don't include a
3191 prerequisite in $+, $^ or $? if d->ignore_mtime.
3194 2002-06-18 Paul D. Smith <psmith@gnu.org>
3196 * make.texinfo: Updates for next revision. New date/rev/etc.
3197 Recreate all Info menus. Change license on the manual to the GNU
3198 Free Documentation License. A number of typos.
3199 (Variables Simplify): Don't use "-" before it's defined.
3200 (Automatic Prerequisites): Rewrite the target example to work
3201 properly if the compile fails. Remove incorrect comments about
3202 how "set -e" behaves.
3203 (Text Functions): Move the "word", "wordlist", "words", and
3204 "firstword" functions here, from "File Name Functions".
3205 * make-stds.texi: Update from latest GNU version.
3206 * fdl.texi: (created) Import the latest GNU version.
3208 2002-06-06 Paul D. Smith <psmith@gnu.org>
3210 * variable.c (do_variable_definition): New function: extract the
3211 part of try_variable_definition() that actually sets the value
3212 into a separate function.
3213 (try_variable_definition): Call do_variable_definition() after
3214 parsing the variable definition string.
3215 (define_variable_in_set): Make the name argument const.
3217 * variable.h (enum variable_flavor): Make public.
3218 (do_variable_definition): Create prototype.
3220 * read.c (read_all_makefiles): Create a new built-in variable,
3222 (read_makefile): Add each makefile read in to this variable value.
3224 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3226 * Makefile.DOS.template: Tweak according to changes in the
3227 distribution. Add back the dependencies of *.o files.
3229 * configh.dos.template: Synchronize with config.h.in.
3231 2002-05-09 Paul D. Smith <psmith@gnu.org>
3233 * file.c (file_timestamp_now): Use K&R function declaration.
3235 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3236 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3237 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3238 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3239 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3240 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3241 nlist.n_name is a pointer rather than an array.
3243 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3244 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3245 * configure.in: Use it instead of the old version.
3247 * main.c (main): Prefer setvbuf() to setlinebuf().
3249 2002-05-08 Paul D. Smith <psmith@gnu.org>
3251 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3252 (loadavg_LDADD): Ditto.
3254 2002-04-29 Paul D. Smith <psmith@gnu.org>
3256 * expand.c (recursively_expand_for_file): Rename
3257 recursively_expand() to recursively_expand_for_file() and provide
3258 an extra argument, struct file. If the argument is provided, set
3259 the variable scope to that of the file before expanding.
3260 * variable.h (recursively_expand): Make this a macro that invokes
3261 recursively_expand_for_file() with a NULL file pointer.
3262 * variable.c (target_environment): Call the renamed function and
3263 provide the current file context.
3264 Fixes Debian bug #144306.
3266 2002-04-28 Paul D. Smith <psmith@gnu.org>
3268 Allow $(call ...) user-defined variables to be self-referencing
3269 without throwing an error. Allows implementation of transitive
3270 closures, among other possibly useful things.
3271 Requested by: Philip Guenther <guenther@sendmail.com>
3273 * variable.h (struct variable): Add a new field: exp_count, and
3274 new macros to hold its size and maximum value.
3275 (warn_undefined): Make this a macro.
3276 * variable.c (define_variable_in_set): Initialize it.
3277 * expand.c (recursively_expand): If we detect recursive expansion
3278 of a variable, check the exp_count field. If it's greater than 0
3279 allow the recursion and decrement the count.
3280 (warn_undefined): Remove this (now a macro in variable.h).
3281 * function.c (func_call): Before we expand the user-defined
3282 function, modify its exp_count field to contain the maximum
3283 number of recursive calls we'll allow. After the call, reset it
3286 2002-04-21 Paul D. Smith <psmith@gnu.org>
3288 Modified to use latest autoconf (2.53), automake (1.6.1), and
3289 gettext (0.11.1). We're using gettext's new "external" support,
3290 to avoid including libintl source with GNU make.
3292 * README.cvs: New file. Explain how to build GNU make from CVS.
3294 * configure.in: Modify checking for the system glob library.
3295 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3296 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3297 etc. will manage it correctly). Set an automake conditional
3298 USE_LOCAL_GLOB to decide whether to compile the glob library.
3300 * getloadavg.c (main): Include make.h in the "TEST" program to
3303 * Makefile.am: Remove special rules for loadavg. Replace them
3304 with Automake capabilities for building extra programs.
3306 * signame.c: This file does nothing if the system provide
3307 strsignal(). If not, it implements strsignal(). If the system
3308 doesn't define sys_siglist, then we make our own; otherwise we use
3310 * signame.h: Removed.
3312 * main.c (main): No need to invoke signame_init(). Update copyright.
3314 * ABOUT-NLS: Removed.
3315 * gettext.c: Removed.
3316 * gettext.h: Get a simplified copy from the gettext package.
3318 * i18n/*.po: Moved to po/.
3321 * config/*: Created. Contains package configuration helper files.
3322 * config.guess, config.sub: Moved to config directory.
3324 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3325 Rework to use new-style autoconf features. Use the "external"
3326 mode for gettext. Make the build.sh config file conditional on
3327 whether build.sh.in exists, to avoid autoconf errors.
3328 * acinclude.m4: Removed almost all macros as being obsolete.
3329 Rewrote remaining macros to use AC_DEFINE.
3330 * acconfig.h: Removed.
3332 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3333 conditional to handle customs support. Remove special handling
3336 2002-04-20 Paul D. Smith <psmith@gnu.org>
3338 * function.c (func_call): Don't mark the argument variables $1,
3339 etc. as recursive. They've already been fully expanded so
3340 there's no need to do it again, and doing so strips escaped $'s.
3341 Reported by Sebastian Glita <glseba@yahoo.com>.
3343 * remake.c (notice_finished_file): Walk through double-colon
3344 entries via the prev field, not the next field!
3345 Reported by Greg McGary <greg@mcgary.org>.
3347 * main.c (main): If the user specifies -q and asks for a specific
3348 target which is a makefile, we got an assert. In that case it
3349 turns out we should continue normally instead.
3351 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3353 * i18n/he.po: Installed a new translation.
3355 2002-01-07 Paul D. Smith <psmith@gnu.org>
3357 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3359 2001-12-04 Paul D. Smith <psmith@gnu.org>
3361 * i18n/ja.po: Installed an updated translation.
3363 2001-09-06 Paul Eggert <eggert@twinsun.com>
3365 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3366 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3368 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3370 (main): Get rid of any avoidable limit on stack size.
3372 2001-09-04 Paul D. Smith <psmith@gnu.org>
3374 * i18n/da.po: Installed an updated translation.
3376 2001-08-03 Paul D. Smith <psmith@gnu.org>
3378 * i18n/fr.po: Installed an updated translation.
3379 Resolves Debian bug #106720.
3381 2001-06-13 Paul D. Smith <psmith@gnu.org>
3383 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3386 2001-06-11 Paul D. Smith <psmith@gnu.org>
3388 * i18n/ko.po: Installed a new translation.
3390 2001-05-06 Paul D. Smith <psmith@gnu.org>
3392 Modify the EINTR handling.
3394 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3395 the way in which we manage the file descriptor/signal handler race
3396 trap to be more efficient.
3398 2001-05-06 Paul Eggert <eggert@twinsun.com>
3400 Restart almost all system calls that are interrupted, instead
3401 of worrying about EINTR. The lone exception is the read() for
3404 * configure.in (HAVE_SA_RESTART): New macro.
3405 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3406 * main.c (main): Use SA_RESTART instead of the old,
3407 nonstandard SA_INTERRUPT.
3409 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3410 * main.c (bsd_signal): New function or macro,
3411 if the implementation doesn't supply it.
3412 (The bsd_signal function will be in POSIX 1003.1-200x.)
3413 (HANDLESIG): Remove.
3414 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3416 * make.h (EINTR_SET): Remove.
3417 (SA_RESTART): New macro.
3419 * arscan.c (ar_member_touch): Don't worry about EINTR.
3420 * function.c (func_shell): Likewise.
3421 * job.c (reap_children, free_child, new_job): Likewise.
3422 * main.c (main): Likewise.
3423 * remake.c (touch_file, name_mtime): Likewise.
3425 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3426 if fstat failed with errno!=EINTR, the error was ignored.
3428 * job.c (set_child_handler_action_flags): New function.
3429 (new_job): Use it to temporarily clear the SIGCHLD action flags
3430 while reading the token.
3432 2001-05-02 Paul D. Smith <psmith@gnu.org>
3434 * job.c (start_job_command): Don't add define/endef per-line flags
3435 to the top-level flags setting.
3437 2001-04-03 Paul D. Smith <psmith@gnu.org>
3439 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3440 bit on error, so check for odd return values, not non-0 return
3442 (VMS_get_member_info): Calculate the timezone differences correctly.
3443 Reported by John Fowler <jfowler@nyx.net>.
3446 2001-03-14 Paul D. Smith <psmith@gnu.org>
3448 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3449 value before invoking define_variable().
3450 Reported by John Fowler <jfowler@nyx.net>.
3452 2001-02-07 Paul D. Smith <psmith@gnu.org>
3454 * read.c (record_target_var): If we reset the variable due to a
3455 command-line variable setting overriding it, turn off the "append"
3458 2001-01-17 Paul D. Smith <psmith@gnu.org>
3460 * variable.c (lookup_variable) [VMS]: When getting values from the
3461 environment, allocate enough space for the _value_ plus escapes,
3462 not enough space for the name plus escapes :-/.
3463 Reported by John Fowler <jfowler@nyx.net>.
3465 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3466 warnings that make generates, so it doesn't look like an error.
3467 Reported by Karl Berry <karl@gnu.org>.
3470 Fix for PR/2020: Rework appended target-specific variables. I'm
3471 fairly confident this algorithm is finally correct.
3473 * expand.c (allocated_variable_append): Rewrite. Instead of
3474 expanding each appended variable then adding all the expanded
3475 strings together, we append all the unexpanded values going up
3476 through the variable set contexts, then expand the final result.
3477 This behaves just like non-target-specific appended variable
3478 values, while the old way didn't in various corner cases.
3479 (variable_append): New function: recursively append the unexpanded
3480 value of a variable, walking from the outermost variable scope to
3482 * variable.c (lookup_variable): Remove the code that looked up the
3483 variable set list if the found variable was "append". We don't
3485 (lookup_variable_in_set): Make this non-static so we can use it
3487 (try_variable_definition): Use lookup_variable_in_set() rather
3488 than faking out current_variable_set_list by hand (cleanup).
3489 * variable.h: Add a prototype for the now non-static
3490 lookup_variable_in_set().
3492 2000-11-17 Paul D. Smith <psmith@gnu.org>
3494 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3495 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3496 before throwing a fit.
3498 2000-11-17 Paul D. Smith <psmith@gnu.org>
3500 * read.c (readline): CRLF calculations had a hole, if you hit the
3501 buffer grow scenario just right. Reworked the algorithm to avoid
3502 the need for len or lastlen at all. Problem description with
3503 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3505 2000-10-24 Paul D. Smith <psmith@gnu.org>
3507 * gettext.c (SWAP): Declare this with the prototype, otherwise
3508 some systems don't work (non-32-bit? Reported for Cray T3E).
3509 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3511 2000-10-05 Paul D. Smith <psmith@gnu.org>
3513 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3514 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3516 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3518 2000-09-22 Paul D. Smith <psmith@gnu.org>
3520 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3521 parts of the real gettext.h here, and we expect to really include
3522 the real gettext.h later. If we keep this #define, it's ignored.
3524 2000-09-21 Paul D. Smith <psmith@gnu.org>
3526 * main.c (log_working_directory): Rework the text to use complete
3527 sentences, to make life simpler for the translators.
3529 2000-08-29 Paul D. Smith <psmith@gnu.org>
3531 * file.c (remove_intermediates): Print a debug message before we
3532 remove intermediate files, so the user (if she uses -d) knows
3535 2000-08-21 Paul D. Smith <psmith@gnu.org>
3537 * variable.c (try_variable_definition): Change how we handle
3538 target-specific append variable defns: instead of just setting the
3539 value, expand it as an append _but_ only within the current
3540 target's context. Otherwise we lose all but the last value if the
3541 variable is appended more than once within the current target
3542 context. Fixes PR/1831.
3544 2000-08-16 Paul D. Smith <psmith@gnu.org>
3546 * function.c (func_shell): Nul-terminate the buffer before
3547 printing an exec error message (just in case it's not!).
3548 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3550 2000-07-25 Paul D. Smith <psmith@gnu.org>
3552 * job.c (construct_command_argv_internal): Add "~" to the list of
3553 sh_chars[] which disallow optimizing out the shell call.
3555 2000-07-23 Paul Eggert <eggert@twinsun.com>
3557 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3558 supersedes --disable-nsec-timestamps.
3559 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3560 * README: Remove --disable-nsec-timestamps.
3562 * filedef.h (struct file.low_resolution_time): New member.
3563 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3564 * remake.c (update_file_1):
3565 Avoid spurious rebuilds due to low resolution time stamps,
3566 generalizing the earlier code that applied only to archive members.
3567 (f_mtime): Archive members always have low resolution time stamps.
3569 * configure.in: Remove --disable-nsec-timestamps, as this has
3570 been superseded by .LOW_RESOLUTION_TIME.
3572 2000-07-23 Paul Eggert <eggert@twinsun.com>
3574 * configure.in (enable_nsec_timestamps): Renamed from
3575 make_cv_nsec_timestamps, since enable/disable options
3576 shouldn't be cached.
3578 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3579 and Paul Eggert <eggert@twinsun.com>
3581 * file.c (file_timestamp_now):
3582 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3583 so that clock_gettime is not linked unless needed.
3585 * filedef.h (FILE_TIMESTAMP_HI_RES):
3586 Remove definition; "configure" now does this.
3588 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3589 to before high resolution file timestamp check,
3590 since that check now uses uintmax_t.
3591 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3592 high resolution file timestamps.
3593 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3594 so that we don't link in clock_gettime unnecessarily.
3596 2000-07-17 Paul D. Smith <psmith@gnu.org>
3598 * i18n/ja.po: New version of the translation file.
3600 2000-07-07 Paul D. Smith <psmith@gnu.org>
3602 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3603 the offset calculation.
3604 (name_mtime): Replace EINTR test with EINTR_SET macro.
3606 2000-07-07 Paul Eggert <eggert@twinsun.com>
3610 * remake.c (update_file_1):
3611 Avoid spurious rebuilds of archive members due to their
3612 timestamp resolution being only one second.
3613 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3614 the clock's resolution being lower than file timestamps'.
3615 When warning about future timestamps, report only the discrepancy,
3616 not the absolute value of the timestamp and the current time.
3618 * file.c (file_timestamp_now): New arg RESOLUTION.
3619 * filedef.h (file_timestamp_now): Likewise.
3620 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3622 2000-07-05 Paul D. Smith <psmith@gnu.org>
3624 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3625 to listp. Fixes PR/1793.
3627 2000-06-26 Paul Eggert <eggert@twinsun.com>
3629 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3631 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3633 * remake.c (f_mtime): Remove unused var memtime.
3635 2000-06-25 Martin Buchholz <martin@xemacs.org>
3637 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3638 Ran spell-check on make.texinfo.

3642 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3643 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3644 * make.h: Define these macros.
3646 * Version 3.79.1 released.
3648 * configure.in: Add a new option, --disable-nsec-timestamps, to
3649 avoid using sub-second timestamps on systems that support it. It
3650 can lead to problems, e.g. if your makefile relies on "cp -p".
3651 * README.template: Document the issue with "cp -p".
3653 * config.guess, config.sub: Updated.
