1 2009-09-26 Paul Smith <psmith@gnu.org>
3 * read.c (record_files): Use free_ns() to free struct nameseq.
6 * rule.c (freerule): Use free_dep_chain().
8 * read.c (record_files): Free FILENAMES chain for implicit rules.
9 (eval): Static pattern targets go into the string cache.
11 * function.c (string_glob): Free NAME in the nameseq chain.
13 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
15 * implicit.c (pattern_search): Terminate early if we haven't
16 found any rules to try (performance improvement).
18 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
20 * implicit.c (pattern_search): Merge three parallel arrays,
21 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
22 of struct TRYRULE. In the old version the latter two arrays
23 had insufficient length.
25 2009-09-24 Paul Smith <psmith@gnu.org>
27 * implicit.c (pattern_search): Add back support for order-only
28 prerequisites for secondary expansion implicit rules, that were
29 accidentally dropped. If we find a "|", enable order-only mode
30 and set IGNORE_MTIME on all deps that are seen afterward.
31 (pattern_search): Fix memory leaks: for intermediate files where
32 we've already set the file variable and pattern variable sets, be
33 sure to either save or free them as appropriate.
35 2009-09-23 Paul Smith <psmith@gnu.org>
37 Rework the way secondary expansion is stored, for efficiency.
38 This changes secondary expansion so that ONLY WHEN we know we have
39 a possibility of needing secondary expansion, do we defer the
40 secondary expansion. This means more parsing the deps but we use
41 a lot less memory (due to the strcache). Also, this fixes
44 * read.c (eval): Don't parse the dep string here anymore.
45 (record_files): Take the dep argument as an unparsed string. If
46 secondary expansion is enabled AND the prereq string has a '$' in
47 it, then set NEED_2ND_EXPANSION and keep the entire string.
48 Otherwise, parse the dep string here to construct the dep list
49 with the names in the strcache.
51 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
52 duplicate the name string (others are in the strcache).
54 * implicit.c: Remove struct idep and free_idep_chain(): unused.
55 (struct patdeps): New structure to store prereq information.
56 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
57 which prerequisites need expansion, and expand only those.
59 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
60 and enter_prereqs(). split_prereqs() takes a fully-expanded string
61 and splits it into a DEP list, handling order-only prereqs.
62 (enter_prereqs): This function enters a list of DEPs into the file
63 database. If there's a stem defined, expand any pattern chars.
64 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
65 set. Use the above functions.
66 (snap_deps): Only perform second expansion on prereqs that need it,
67 as defined by the NEED_2ND_EXPANSION flag.
68 (print_prereqs): New function to print the prereqs
69 (print_file): Call print_prereqs() rather than print inline.
71 * hash.h (STRING_COMPARE): Take advantage of strcache() by
73 (STRING_N_COMPARE): Ditto.
74 (ISTRING_COMPARE): Ditto.
76 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
77 (parse_file_seq): Return void*
78 * read.c (parse_file_seq): Return void*.
79 (eval): Invoke macroized version of parse_file_seq()
80 * default.c (set_default_suffixes): Ditto.
81 * file.c (split_prereqs): Ditto.
82 * function.c (string_glob): Ditto.
83 * main.c (main): Ditto.
84 * rule.c (install_pattern_rule): Ditto.
86 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
88 2009-09-16 Paul Smith <psmith@gnu.org>
90 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
92 * dep.h: Create alloc_dep() / free_dep() macros.
94 * implicit.c (pattern_search): Take advantage of the new
95 parse_file_seq() to add the directory prefix to each prereq.
97 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
98 all. Avoid reversing chains. Support adding prefixes.
99 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
100 cached/non-cached results.
101 (eval): Remove multi_glob() & invoke new parse_file_seq().
102 * rule.c (install_pattern_rule): Ditto.
103 * main.c (main): Ditto.
104 * implicit.c (pattern_search): Ditto.
105 * function.c (string_glob): Ditto.
106 * file.c (parse_prereqs): Ditto.
107 * default.c (set_default_suffixes): Ditto.
109 * variable.c (parse_variable_definition): Don't run off the end of
110 the string if it ends in whitespace (found with valgrind).
112 * commands.c (set_file_variables): Keep space for all targets in
113 $? if -B is given (found with valgrind).
115 2009-09-15 Paul Smith <psmith@gnu.org>
117 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
118 (xcalloc): Add new function.
119 * make.h: New declarations.
121 * ar.c (ar_glob_match): New calling method for concat().
122 * main.c (main): Ditto.
123 (decode_env_switches): Ditto.
124 * read.c (eval_makefile): Ditto.
125 (tilde_expand): Ditto.
126 (parse_file_seq): Ditto.
127 * variable.c (target_environment): Ditto.
128 (sync_Path_environment): Ditto.
130 * ar.c (ar_glob_match): Use xcalloc().
131 * dir.c (file_impossible): Ditto.
132 * file.c (enter_file): Ditto.
133 * job.c (new_job): Ditto.
134 * read.c (parse_file_seq): Ditto.
135 * vmsfunctions.c (opendir): Ditto.
137 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
139 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
140 inside the loop that looks up environment for PATH.
142 2009-08-31 Eli Zaretskii <eliz@gnu.org>
144 * function.c (windows32_openpipe): Update envp after calling
145 sync_Path_environment.
147 2009-08-02 Paul Smith <psmith@gnu.org>
149 * remake.c (notice_finished_file): Ensure file->cmds is not null
150 before looping through them. Fixes Savannah bug #21824.
152 * doc/make.texi (Wildcard Examples): Clarify when objects is
153 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
154 (Include): Clarify the behavior of -include.
155 Fixes Savannah bug #18963.
157 2009-08-01 Paul Smith <psmith@gnu.org>
159 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
160 etc. come on the command line. Fixes Savannah bug #27093.
162 * expand.c (expand_argument): If the argument is large enough use
163 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
165 * variable.c (do_variable_definition): Avoid using alloca() to
166 hold values, which can be large. Fixes Savannah bug #23960.
168 * job.c (new_job): Use memmove() instead of strcpy() since both
169 pointers are in the same memory block. Fixes Savannah bug #27148.
170 Patch by Petr Machata.
172 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
174 * job.c (construct_command_argv_internal): Add "ulimit" and
175 "unset" to the sh_cmds for Unixy shells.
177 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
179 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
180 that set make_cv_sys_gnu_glob, so they are also correctly set
181 when the cache has been populated before.
183 2009-07-04 Eli Zaretskii <eliz@gnu.org>
185 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
186 exist, as realpath(3) does where it's supported.
188 2006-07-04 Eli Zaretskii <eliz@gnu.org>
190 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
191 (abspath): Support systems that define HAVE_DOS_PATHS (have
192 drive letters in their file names). Use IS_PATHSEP instead of a
193 literal '/' comparison. Fixes Savannah bug #26886.
195 2009-06-14 Paul Smith <psmith@gnu.org>
197 * remake.c (update_file_1): Remember the original file we marked
198 as updating, so we can clear that flag again. If we find a target
199 via vpath, FILE might change.
200 (check_dep): Ditto. Fixes Savannah bug #13529.
201 Patch by Reid Madsen <reid.madsen@tek.com>.
203 2009-06-13 Paul Smith <psmith@gnu.org>
205 * doc/make.texi (MAKEFILES Variable): Be explicit that files
206 included by MAKEFILES cannot give default goals.
207 * read.c (eval): If set_default is not set, pass the no-default-goal
208 value when we read included makefiles. Fixes Savannah bug #13401.
210 * ar.c (ar_name): Ensure that targets with empty parens aren't
211 considered archive member references: archive members must have a
212 non-empty "member" string. Fixes Savannah bug #18435.
214 * function.c (string_glob): Rely on multi_glob() to determine
215 whether files exist or not. Remove call to file_exists_p() which
216 is not always correct. Fixes Savannah bug #21231.
217 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
218 then only files that really exist will be returned.
219 * dep.h: Add new argument to multi_glob().
220 * rule.c (install_pattern_rule): Ditto.
221 * read.c (eval): Ditto.
222 * main.c (main): Ditto.
223 * implicit.c (pattern_search): Ditto.
224 * file.c (parse_prereqs): Ditto.
225 * default.c (set_default_suffixes): Ditto.
227 2009-06-09 Paul Smith <psmith@gnu.org>
229 * commands.c (set_file_variables): If always_make_flag is set,
230 always add the prereq to $?. Fixes Savannah bug #17825.
232 * remake.c (update_file_1): When rebuilding deps of FILE, also try
233 to rebuild the deps of all the also_make targets for that file.
234 Fixes Savannah bug #19108.
236 * implicit.c (pattern_search): Undo test for is_target, added by
237 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
238 Rule Search Algorithm". Fixes Savannah bug #17752.
240 * main.c (clean_jobserver): Clear the jobserver_fds options and
241 set job_slots to the default when we clean up.
242 (define_makeflags): Return the new MAKEFLAGS value.
243 (main): Reset MAKEFLAGS in the environment when we re-exec.
244 Fixes Savannah bug #18124.
246 2009-06-08 Paul Smith <psmith@gnu.org>
248 * read.c (eval): Collapse continuations post-semicolon on target-
249 specific variables. Fixes Savannah bug #17521.
251 2009-06-07 Paul Smith <psmith@gnu.org>
253 * job.c (reap_children): For older systems without waitpid() (are
254 there any of these left?) run wait(2) inside EINTRLOOP to handle
255 EINTR errors. Fixes Savannah bug #16401.
257 * (various): Debug message cleanup. Fixes Savannah bug #16469.
259 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
261 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
262 not the end, to catch second expansion $(eval ...) defining new
263 target/prereq relationships during snap_deps.
264 Fixes Savannah bug #24622.
266 * read.c (record_files): The second-expansion "f->updating" hack
267 was not completely correct: if assumed that the target with
268 commands always had prerequisites; if one didn't then the ordering
269 was messed up. Fixed for now to use f->updating to decide whether
270 to preserve the last element in the deps list... but this whole
271 area of constructing and reversing the deps list is too confusing
272 and needs to be reworked. Fixes Savannah bug #21198.
274 2009-06-06 Paul Smith <psmith@gnu.org>
276 * hash.c (hash_insert): Remove useless test for NULL.
277 Fixes Savannah bug #21823.
279 * make.h: Move SET_STACK_SIZE determination to make.h.
280 * main.c (main): New global variable, STACK_LIMIT, holds the
281 original stack limit when make was started.
282 * job.c (start_job_command): Reset the stack limit, if we changed it.
283 Fixes Savannah bug #22010.
285 * remake.c (check_dep): Only set the target's state to not-started
286 if it's not already running. Found this while testing -j10 builds
287 of glibc: various targets were being rebuilt multiple times.
288 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
291 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
292 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
295 2009-06-04 Paul Smith <psmith@gnu.org>
297 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
299 * maintMakefile: Modify access of config and gnulib Savannah
300 modules to use GIT instead of CVS.
302 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
303 Fixes Savannah bug #24655.
305 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
306 this can happen during some invocations of $(eval ...) for example.
307 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
309 2009-06-02 Paul Smith <psmith@gnu.org>
311 * configure.in: Check for fileno()
312 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
313 for the makefile file so invocations of $(shell ...) don't inherit it.
314 Fixes Savannah bug #24277.
316 2009-06-01 Paul Smith <psmith@gnu.org>
318 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
319 expansion was handled incorrectly. Rework the default goal
320 handling to save the variable only. Remove default_goal_file and
322 * read.c (eval): Check default_goal_var, not default_goal_name.
323 * read.c (record_target_var): Don't check default_goal_file here.
325 2009-05-31 Paul Smith <psmith@gnu.org>
327 * main.c (main): Expand the .DEFAULT_GOAL variable before using
328 it, and if the multi_glob() returns nothing (say it expanded to
329 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
331 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
332 $(and ..) to the reference. Fixes Savannah bug #25694.
334 * make.1: Be clear that some recipes will be executed even with -n.
335 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
337 * doc/make.texi (Override Directive): Make more clear how
338 overrides and appends interact.
339 Elucidates part of Savannah bug #26207.
341 * read.c (record_target_var): Don't reset the origin on
342 target-specific variables; try_variable_definition() will handle
343 this correctly. Fixes Savannah bug #26207.
345 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
346 Fixes Savannah bug #25712.
348 * implicit.c (pattern_search): Keep a pointer to the beginning of
349 the filename and save that instead of the constructed pointer.
350 Fixes Savannah bug #26593.
351 Patch by Mark Seaborn <mrs@mythic-beasts.com>
353 2009-05-30 Paul Smith <psmith@gnu.org>
355 * doc/make.texi (Multi-Line): Add a description of the new abilities
356 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
357 "command sequence" vs. "recipe" syntax.
358 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
359 after a define, to create variables with those flavors.
361 2009-05-25 Paul Smith <psmith@gnu.org>
363 Reworked the parser for variable assignments to allow multiple
364 modifiers, and in any order. Also allows variable and
365 prerequisites to be modifier names ('export', 'private', etc.)
367 * NEWS: Add notes about user-visible changes.
369 * read.c (struct vmodifiers): Remember what modifiers were seen.
370 (parse_var_assignment): New function to parse variable assignments.
371 (eval): Call the new function. Handle variable assignments earlier.
373 * variable.c (parse_variable_definition): Only parse; don't create var.
374 (assign_variable_definition): Call parse, then create the var.
376 2009-05-24 Paul Smith <psmith@gnu.org>
378 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
379 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
381 2009-03-14 Eli Zaretskii <eliz@gnu.org>
383 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
384 Fixes Savannah bug #25412.
386 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
387 prototype for xmalloc.
388 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
389 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
390 Loop over an array of extensions, instead of duplicating the same
391 code inline. Use SearchPath followed by CreateFile, instead of
392 the obsolete OpenFile. Fixes Savannah bug #17277.
393 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
394 to `find_file'. Fixes Savannah bug #25662.
396 2009-03-07 Eli Zaretskii <eliz@gnu.org>
398 * function.c (func_shell): Don't close pipedes[1] if it is -1.
399 Fixes Savannah bug #20495.
401 2009-02-28 Ralf Wildenhues <address@hidden>
403 * doc/make.texi (Instead of Execution): Document interaction of
404 -t with phony targets.
406 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
408 Introduce a new keyword "private" which applies to target-specific
409 variables and prevents their values from being inherited.
411 * variable.h (struct variable): Add private_var flag to each variable.
412 Add a flag to specify which list entry switches to the parent target.
413 * variable.c (define_variable_in_set): Initialize private_var flag.

432 2008-09-30 Eli Zaretskii <eliz@gnu.org>
434 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
437 * w32/subproc/build.bat (GCCBuild): Likewise.
439 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
441 * job.c (construct_command_argv_internal): Avoid extra backslash
442 in batch-mode Unixy shells. Under DB_JOBS, display the contents
445 2008-05-31 Eli Zaretskii <eliz@gnu.org>
447 * README.W32.template: Remove obsolete text about non-support for
448 -jN without Unixy shell. Remove obsolete text about not supplying
449 Visual Studio project files (we do supply them). Modify text to
450 prefer GCC builds to MSC builds.
452 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
454 * doc/make.texi (Empty Targets): Fix typo.

469 `value' field is NULL.
471 2007-12-22 Eli Zaretskii <eliz@gnu.org>
473 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
475 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
476 (TEXINFOS): Value changed to `doc/make.texi'.
477 (.SUFFIXES): Use .texi instead of .texinfo.
478 (make.info, make.dvi): Depend on doc/make.texi.
479 (.texi.info): New target, instead of ".texinfo.info". Change -I
480 switch to $(MAKEINFO) to look in doc/. Use --no-split.
481 (.texi): New target, instead of ".texinfo". Change -I switch to
482 $(MAKEINFO) to look in doc/. Use --no-split.
483 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
484 switch to $(MAKEINFO) to look in doc/.
485 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
486 "*.i[0-9][0-9]" (due to --no-split above).
487 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
488 (html, make_1.html): New targets.
489 (.PHONY): Add "html".
490 (.SUFFIXES): Add .html.
492 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
494 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
495 HAVE_DECL_SYS_SIGLIST.
497 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
498 build does not use child_execute_job.
500 * variable.c (define_automatic_variables) [__MSDOS__]: Always
501 export the SHELL environment variable to the child.
503 2007-12-22 Eli Zaretskii <eliz@gnu.org>
505 * config.h.W32: Include sys/types.h.
506 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
508 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
509 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
512 2007-11-04 Paul Smith <psmith@gnu.org>
514 * doc/make.texi: Convert references to "commands", "command
515 lines", and "command script" to "recipe".
517 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
520 2007-10-27 Bruno Haible <bruno@clisp.org>
522 * remake.c (f_mtime): Print time difference values between 100 and
523 ULONG_MAX in fixed-point notation rather than in exponention notation.
525 2007-10-12 Eli Zaretskii <eliz@gnu.org>
527 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
528 a more complex value than a simple shell: if it's not a default
529 shell now then expand it and see if is a default shell then.
531 2007-10-10 Eli Zaretskii <eliz@gnu.org>

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

560 "Special Variables" section.

564 (Command Syntax): Ditto.
565 (Error Messages): Ditto.
567 2007-09-10 Paul Smith <psmith@gnu.org>
569 * commands.c (print_commands): Don't print an extra line in the
570 command scripts. Prefix the command scripts with cmd_prefix, not \t.

573 were chopping the last char.
575 * NEWS: Announce the .RECIPEPREFIX special variable.

589 2007-08-15 Paul Smith <psmith@gnu.org>

655 Dave Korn <dave.korn@artimi.com>
657 2007-05-08 Paul Smith <psmith@gnu.org>
659 Fix Savannah bug #19656:
661 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
663 * make.h: Change all case-insensitive string compares to use
664 strcasecmp() (from POSIX). If we don't have that but do have one
665 of the others, define strcasecmp to be one of those instead. If
666 we don't have any, declare a prototype for our own version.
668 * misc.c (strcasecmp): Use this if we can't find any native
669 case-insensitive string comparison function.
670 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
671 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
673 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
674 strcasecmp() instead of stricmp().
675 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
676 instead of strcmpi().
677 * acinclude.m4: Remove the strcasecmp() check from here.
679 2007-03-21 Paul Smith <psmith@gnu.org>
681 * configure.in: Don't turn on case-insensitive file system support
682 if --disable-... is given. Fixes Savannah bug #19348.
684 2007-03-19 Paul Smith <psmith@gnu.org>
686 * ALL: Use the strcache for all file name strings, or other
687 strings which we will never free. The goal is to save memory by
688 avoiding duplicate copies of strings. However, at the moment this
689 doesn't save much memory in most situations: due to secondary
690 expansion we actually save prerequisite lists twice (once before
691 the secondary expansion, and then again after it's been parsed
692 into individual file names in the dep list). We will resolve this
693 in a future change, by doing the parsing up-front for targets
694 where secondary expansion is not set.
696 Moving things into the strcache also allows us to use const
697 pointers in many more places.
699 2007-01-03 Paul Smith <psmith@gnu.org>
701 * make.h (ENULLLOOP): Reset errno after each failed invocation of
702 the function, not just the first. Fixes Savannah bug #18680.
704 2006-11-18 Paul Smith <psmith@gnu.org>
706 * strcache.c (strcache_add_len): Don't allocate a new buffer
707 unless the string is not already nil-terminated. Technically this
708 is a violation of the standard, since we may be passed an array
709 that is not long enough to test one past. However, in make this
710 is never true since we only use nil-terminated strings or
713 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
715 * main.c: New global cmd_prefix, defaults to '\t'.
716 * job.c (construct_command_argv_internal): Use cmd_prefix instead
720 (dir_contents_file_exists_p): Check for an error return from
721 readdir(), just in case.
723 * commands.c: Constified.
724 * default.c: Constified.
725 * expand.c: Constified.
726 * function.c: Partial constification.
727 * variable.c: Partial constification.

733 2006-11-16 Eli Zaretskii <eliz@gnu.org>
735 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
736 backslashes and drive letters as absolute.
738 2006-10-22 Paul Smith <psmith@gnu.org>
740 * main.c (struct command_switch): Use const and void*.
742 2006-10-21 Paul Smith <psmith@gnu.org>
745 * arscan.c: Constified.
747 2006-09-30 Paul Smith <psmith@gnu.org>
749 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
750 point to lastword since the example was updated.
751 Fixes Savannah bug #16304.
752 (Secondary Expansion): Correct example description.
753 Fixes Savannah bug #16468.
754 (Makefile Contents): Clarify that comments cannot appear within
755 variable references or function calls.
756 Fixes Savannah bug #16577.
757 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
758 Fixes Savannah bug #17701.
759 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
760 (Prerequisite Types): Added an example of using order-only
761 prerequisites. Fixes Savannah bug #17880.

807 2006-04-20 Paul D. Smith <psmith@gnu.org>
809 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
810 that don't have extended grep.
811 (cvsclean): Use $(PERL) instead of perl.
813 2006-04-09 Paul D. Smith <psmith@gnu.org>
815 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
817 * expand.c, implicit.c, main.c, read.c: Rename variables so that
818 inner-scope variables don't mask outer-scope variables.

876 with lastslash, since the latter points to filename, not to
878 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
879 Declare and define sh_chars_sh[].
881 2006-03-23 Paul D. Smith <psmith@gnu.org>
883 * configure.in: Look for build.sh.in in $srcdir so it will be
884 built for remote configurations as well.

887 Fixes Savannah bug #16166.
889 * misc.c (log_access): Takes a const char *.
890 * function.c (fold_newlines): Takes an unsigned int *.
891 Both fixes for Savannah bug #16170.
893 2006-03-22 Boris Kolpackov <boris@kolpackov.net>

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

970 * commands.c (set_file_variables): Realloc, not malloc, the static
971 string values to avoid memory leaks.
973 * expand.c (recursively_expand_for_file): Only set reading_file to
974 an initialized value.
976 * implicit.c (pattern_search): We need to make a copy of the stem
977 if we get it from an intermediate dep, since those get freed.

993 prevent compiler warnings.

1003 * variable.c (merge_variable_set_lists): Don't try to merge the

1005 circularities in the linked list, if global_setlist->next in one
1006 list gets set to point to another list which also ends in

1010 2006-02-15 Paul D. Smith <psmith@gnu.org>
1012 Fix for Savannah bug #106.
1014 * expand.c (expanding_var): Keep track of which variable we're
1015 expanding. If no variable is being expanded, it's the same as
1017 * make.h (expanding_var): Declare it.
1018 * expand.c (recursively_expand_for_file): Set expanding_var to the
1019 current variable we're expanding, unless there's no file info in
1020 it (could happen if it comes from the command line or a default
1021 variable). Restore it before we exit.

1037 an impossible file, free it.
1038 * variable.c (free_variable_set): New function.
1039 * variable.h: Declare it.
1041 * read.c (read_all_makefiles): Makefile names are kept in the
1042 strcache, so there's never any need to alloc/free them.

1046 archive support is enabled.

1061 A new internal capability: the string cache is a read-only cache
1062 of strings, with a hash table interface for fast lookup. Nothing
1063 in the cache will ever be freed, so there's no need for reference
1064 counting, etc. This is the beginning of a full solution for
1065 Savannah bug #15182, but for now we only store makefile names here.
1067 * strcache.c: New file. Implement a read-only string cache.
1068 * make.h: Add prototypes for new functions.
1069 * main.c (initialize_global_hash_tables): Initialize the string cache.

1085 * doc/make.texi (Conditional Functions): Changed the "if" section
1086 to one on general conditional functions. Added documentation for
1087 $(and ...) and $(or ...) functions.
1088 * NEWS: Note new $(and ...) and $(or ...) functions.
1090 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1092 * job.h (struct child): Add the dontcare bitfield.
1093 * job.c (new_job): Cache dontcare flag.
1094 * job.c (reap_children): Use cached dontcare flag instead of the
1095 one in struct file. Fixes Savannah bug #15641.
1097 2006-02-06 Paul D. Smith <psmith@gnu.org>
1099 * vpath.c (selective_vpath_search): If the file we find has a
1100 timestamp from -o or -W, use that instead of the real time.
1101 * remake.c (f_mtime): If the mtime is a special token from -o or
1102 -W, don't overwrite it with the real mtime.
1103 Fixes Savannah bug #15341.
1105 Updates from Markus Mauhart <qwe123@chello.at>:
1107 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1108 (process_signal, process_last_err, process_exit_code): Manage
1109 invalid handle values.
1110 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1111 manage invalid handles; remove them.
1112 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1113 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1114 * README.cvs: Updates for building from CVS.
1116 2006-02-05 Paul D. Smith <psmith@gnu.org>
1118 * file.c (enter_file): Keep track of the last double_colon entry,
1119 to avoid walking the list every time we want to add a new one.
1120 Fixes Savannah bug #15533.
1121 * filedef.h (struct file): Add a new LAST pointer.
1123 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1124 the comparison. For 64-bits systems the result of the subtraction
1125 might not fit into an int. Use comparison instead.
1126 Fixes Savannah bug #15534.
1128 * doc/make.texi: Update the chapter on writing commands to reflect
1129 the changes made in 3.81 for backslash/newline and SHELL handling.
1131 2006-02-01 Paul D. Smith <psmith@gnu.org>
1133 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure

1147 * prepare_w32.bat: Remove this file from the distribution.
1149 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1151 * remake.c (update_goal_chain): Set g->changed instead of
1152 incrementing it, as it is only 8-bit wide, and could overflow if
1153 many commands got started in update_file.
1155 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1157 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1158 MAXIMUM_WAIT_OBJECTS.
1159 (process_wait_for_any_private): Change dimension of handles[]
1160 array to MAXIMUM_WAIT_OBJECTS.
1161 (process_used_slots): New function.
1162 (process_register): Don't register more processes than the
1163 available number of slots.
1164 (process_easy): Don't start new processes if all slots are used up.
1166 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1167 are already more children than sub_proc.c can handle, behave as if
1168 the load were too high.
1169 (start_job_command): Fix a typo in error message when process_easy
1172 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1174 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1175 the shell is not sh.exe.
1177 * job.c (create_batch_file): Renamed from create_batch_filename;
1178 all callers changed. Don't close the temporary file; return its
1179 file descriptor instead. New arg FD allows to return the file
1181 (construct_command_argv_internal): Use _fdopen instead of fopen to
1182 open the batch file.
1184 2006-01-04 Paul D. Smith <psmith@gnu.org>
1186 * readme.vms: Updates for case-insensitive VMS file systems from
1187 Hartmut Becker <Hartmut.Becker@hp.com>.
1188 * dir.c (vms_hash): Ditto.
1189 * vmsify.c (copyto): Ditto.

1192 * make.1: Add a section on the exit codes for make.
1194 * doc/make.texi: A number of minor updates to the documentation.
1196 2006-01-03 Paul D. Smith <psmith@gnu.org>
1198 * remake.c (update_file_1): Mark a prerequisite changed if it
1201 * read.c (eval): Be sure to strip off trailing whitespace from the
1202 prerequisites list properly. Also, initialize all fields in
1203 struct dep when creating a new one.
1205 2005-12-28 Paul D. Smith <psmith@gnu.org>
1207 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1208 disable warnings for MSC.
1209 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1211 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1213 * doc/make.texi (Execution): Add a footnote about changes in
1214 handling of backslash-newline sequences. Mention the differences
1215 on MS-DOS and MS-Windows.
1217 * NEWS: More details about building the MinGW port and a pointer
1218 to README.W32. Fix the section name that describes the new
1219 backward-incompatible processing of backslash-newline sequences.
1220 The special processing of SHELL set to "cmd" is only relevant to
1221 MS-Windows, not MS-DOS.
1223 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1225 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1226 to DWORD, to avoid compiler warnings.
1227 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1228 use %ld in format, to avoid compiler warnings.
1230 * doc/make.texi (Special Targets): Fix a typo.
1231 (Appending): Fix cross-reference to Setting.
1232 (Special Variables, Secondary Expansion, File Name Functions)
1233 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1234 periods after a sentence.
1235 (Execution): Add @: after "e.g.".
1236 (Environment): Fix punctuation.
1237 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1238 (Shell Function, Target-specific): Add @: after "vs."
1240 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1242 * read.c (record_target_var): Initialize variable's export field
1243 with v_default instead of leaving it "initialized" by whatever
1244 garbage happened to be on the heap.
1246 2005-12-12 Paul D. Smith <psmith@gnu.org>
1248 * make.1: Fix some display errors and document all existing options.
1249 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1251 2005-12-11 Paul D. Smith <psmith@gnu.org>
1253 * implicit.c (pattern_search): If 2nd expansion is not set for
1254 this implicit rule, replace the pattern with the stem directly,
1255 and don't re-expand the variable list. Along with the other
1256 .SECONDEXPANSION changes below, fixes bug #13781.
1258 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1260 * implicit.c (pattern_search): Mark other files that this rule
1261 builds as targets so that they are not treated as intermediates
1262 by the pattern rule search algorithm. Fixes bug #13022.
1264 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1266 * remake.c (notice_finished_file): Propagate the change of
1267 modification time to all the double-colon entries only if
1268 it is the last one to be updated. Fixes bug #14334.
1270 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1272 * function.c (func_flavor): Implement the flavor function which
1273 returns the flavor of a variable.
1274 * doc/make.texi (Functions for Transforming Text): Document it.
1275 * NEWS: Add it to the list of new functions.
1277 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1279 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1281 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1282 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1284 2005-10-26 Paul Smith <psmith@gnu.org>
1286 * read.c (record_files): Don't set deps flags if there are no deps.
1287 * maintMakefile: We only need to build the templates when we are
1288 creating a distribution, so don't do it for "all".
1290 2005-10-24 Paul D. Smith <psmith@gnu.org>
1292 Make secondary expansion optional: its enabled by declaring the
1293 special target .SECONDEXPANSION.
1295 * NEWS: Update information on second expansion capabilities.
1296 * doc/make.texi (Secondary Expansion): Document the
1297 .SECONDEXPANSION special target and its behavior.
1298 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1299 prerequisite list was found in a static pattern rule.
1300 (free_dep_chain): Declare a prototype.
1301 * file.c (parse_prereqs): New function: break out some complexity
1303 (expand_deps): If we aren't doing second expansion, replace % with
1304 the stem for static pattern rules. Call the new function.
1305 * filedef.h (parse_prereqs): Declare a prototype.
1306 * implicit.c (pattern_search): Initialize the new staticpattern
1308 * main.c (second_expansion): Declare a global variable to remember
1309 if the special target has been seen. Initialize the new
1310 staticpattern field for prerequisites.
1311 * make.h: Extern for second_expansion.
1312 * misc.c (free_dep_chain): New function: frees a struct dep list.
1313 * read.c (read_all_makefiles): Initialize the staticpattern field.
1314 (eval_makefile): Ditto.
1315 (record_files): Check for the .SECONDEXPANSION target and set
1316 second_expansion global if it's found.
1317 Use the new free_dep_chain() instead of doing it by hand.
1318 Set the staticpattern field for prereqs of static pattern targets.
1320 2005-10-16 Paul D. Smith <psmith@gnu.org>
1322 * main.c (main): Set CURDIR to be a file variable instead of a
1323 default, so that values of CURDIR inherited from the environment
1324 won't override the make value.
1326 2005-09-26 Paul D. Smith <psmith@gnu.org>
1328 * job.c (construct_command_argv_internal): If the line is empty
1329 remember to free the temporary argv strings.
1332 2005-09-16 Paul D. Smith <psmith@gnu.org>
1334 * job.c (start_job_command): The noerror flag is a boolean (single
1335 bit); set it appropriately.
1336 Reported by Mark Eichin <eichin@metacarta.com>
1338 2005-08-29 Paul D. Smith <psmith@gnu.org>
1340 * function.c (func_error): On Windows, output from $(info ...)
1341 seems to come in the wrong order. Try to force it with fflush().
1343 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1345 * read.c (record_files): Move code that sets stem for static
1346 pattern rules out of the if (!two_colon) condition so it is
1347 also executed for two-colon rules. Fixes Savannah bug #13881.
1349 2005-08-08 Paul D. Smith <psmith@gnu.org>
1351 * make.h: Don't test that __STDC__ is non-0. Some compilers
1352 (Windows for example) set it to 0 to denote "ISO C + extensions".
1355 2005-08-07 Paul D. Smith <psmith@gnu.org>
1357 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1358 conditional (slightly different version of a fix from Eli).
1360 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1361 If make is running in parallel without -k and two jobs die in a
1362 row, but not too close to each other, then make will quit without
1363 waiting for the rest of the jobs to die.
1365 * main.c (die): Don't reset err before calling reap_children() the
1366 second time: we still want it to be in the error condition.
1367 * job.c (reap_children): Use a static variable, rather than err,
1368 to control whether or not the error message should be printed.
1370 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1372 * w32/subproc/sub_proc.c: Include signal.h.
1373 (process_pipe_io, process_file_io): Pass a pointer to a local
1374 DWORD variable to GetExitCodeProcess. If the exit code is
1375 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1377 * job.c [WINDOWS32]: Include windows.h.
1378 (main_thread) [WINDOWS32]: New global variable.
1379 (reap_children) [WINDOWS32]: Get the handle for the main thread
1380 and store it in main_thread.
1382 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1383 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1384 doing anything else. When we are done, close the main thread
1385 handle and exit with status 130.
1387 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1389 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1392 * main.c (find_and_set_default_shell): If found a DOSish shell,
1393 set sh_found and the value of default_shell, and report the
1394 findings in debug mode.
1396 * job.c (construct_command_argv_internal): Check unixy_shell, not
1397 no_default_sh_exe, to decide whether to use Unixy or DOSish
1400 * README.W32: Update with info about the MinGW build.
1402 * build_w32.bat: Support MinGW.
1404 * w32/subproc/build.bat: Likewise.
1406 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1407 printing DWORD args.
1409 * function.c (windows32_openpipe): Fix format strings for printing
1412 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1414 (start_job_command): Fix format string for printing the result of
1416 (start_job_command) [WINDOWS32]: Do not define.
1417 (exec_command): Fix format string for printing HANDLE args.
1419 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1420 to avoid compiler warnings.
1421 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1422 (Note: some of these fixes were submitted independently by J. Grant)
1424 2005-07-30 J. Grant <jg@jguk.org>
1426 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1427 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1428 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1430 2005-07-15 Paul Smith <psmith@gnu.org>
1432 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1433 we don't have a POSIX shell, then revert to the old
1434 backslash-newline behavior (where they are stripped).
1437 2005-07-08 Paul D. Smith <psmith@gnu.org>
1439 * config.h.W32.template: Reorder to match the standard config.h,
1440 for easier comparisons.
1441 From J. Grant <jg@jguk.org>
1443 * maintMakefile: Remove .dep_segment before overwriting it, in
1444 case it's not writable or noclobber is set.
1445 * expand.c (variable_expand_string): Cast result of pointer
1446 arithmetic to avoid a warning.
1447 * main.c (switches): Add full-fledged final initializer.
1449 2005-07-06 Paul D. Smith <psmith@gnu.org>
1451 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1452 * signame.c (strsignal): If we found _sys_siglist[] or
1453 __sys_siglist[] use those instead of sys_siglist[].
1454 From Albert Chin <china@thewrittenword.com>
1456 2005-07-04 Paul D. Smith <psmith@gnu.org>
1458 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1459 globfree(); set up to use the GNU versions.
1460 From Martin Zinser <zinser@zinser.no-ip.info>
1462 2005-07-03 Paul D. Smith <psmith@gnu.org>
1464 From J. Grant <jg@jguk.org>:
1466 * README.W32.template: Update the Windows and tested MSVC versions.
1467 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1468 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1469 * build_w32.bat: Ditto.
1470 * w32/subproc/build.bat: Ditto.
1472 2005-06-28 Paul D. Smith <psmith@gnu.org>
1474 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1475 declaration was checked but not present.
1477 2005-06-27 Paul D. Smith <psmith@gnu.org>
1479 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1480 to unsigned long. Fixes Savannah bug #13550.
1482 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1483 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1484 Fixes Savannah bug #13551.
1486 2005-06-26 Paul D. Smith <psmith@gnu.org>
1488 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1489 it if ANSI_STRING is not set.
1491 2005-06-25 Paul D. Smith <psmith@gnu.org>
1493 * read.c (eval): If no filenames are passed to any of the
1494 "include" variants, don't print an error.
1495 * doc/make.texi (Include): Document this.
1496 Fixes Savannah bug #1761.
1498 * job.c (construct_command_argv_internal): Sanitize handling of
1499 backslash/newline pairs according to POSIX: that is, keep the
1500 backslash-newline in the command script, but remove a following
1501 TAB character, if present. In the fast path, make sure that the
1502 behavior matches what the shell would do both inside and outside
1503 of quotes. In the slow path, quote the backslash and put a
1504 literal newline in the string.
1505 Fixes Savannah bug #1332.
1506 * doc/make.texi (Execution): Document the new behavior and give
1508 * NEWS: Make a note of the new behavior.
1510 * make.h [WINDOWS32]: #include <direct.h>.
1511 Fixes Savannah bug #13478.
1513 * remake.c (name_mtime): If the stat() of a file fails and the -L
1514 option was given and the file is a symlink, take the best mtime of
1515 the symlink we can get as the mtime of the file and don't fail.
1516 Fixes Savannah bug #13280.
1518 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1519 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1520 inside a variable reference. Make this function static as it's
1522 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1523 parsing an unexpanded line looking for semicolons.
1524 Fixes Savannah bug #1454.
1525 * misc.c (remove_comments): Move this to read.c and make it static
1526 as it's only used there. Call find_char_unquote() with new arg.
1527 * make.h: Remove prototypes for find_char_unquote() and
1528 remove_comments() since they're static now.
1530 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1531 its export flag and obtain its value. When we need to re-exec,
1532 increment the value and add it into the environment.
1533 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1534 * NEWS: Mention MAKE_RESTARTS.
1535 * main.c (always_make_set): New variable. Change the -B option to
1536 set this one instead.
1537 (main): When checking makefiles, only set always_make_flag if
1538 always_make_set is set AND the restarts flag is 0. When building
1539 normal targets, set it IFF always_make_set is set.
1540 (main): Avoid infinite recursion with -W, too: only set what-if
1541 files to NEW before we check makefiles if we've never restarted
1542 before. If we have restarted, set what-if files to NEW _after_ we
1544 Fixes Savannah bug #7566:
1546 2005-06-17 Paul D. Smith <psmith@gnu.org>
1548 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1549 in the prerequisites list.
1551 2005-06-12 Paul D. Smith <psmith@gnu.org>
1553 Fix Savannah bug # 1328.
1555 * configure.in: Check for atexit().
1556 * misc.c (close_stdout): Test stdout to see if writes to it have
1557 failed. If so, be sure to exit with a non-0 error code. Based on
1558 code found in gnulib.
1559 * make.h: Prototype.
1560 * main.c (main): Install close_stdout() with atexit().
1562 2005-06-10 Paul D. Smith <psmith@gnu.org>
1564 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1566 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1567 headers; make vmsWaitForChildren() static; extern vmsify().
1568 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1569 Don't create child_execute_job() here (it's in vmsjobs.c).
1570 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1572 2005-06-09 Paul D. Smith <psmith@gnu.org>
1574 * variable.c (push_new_variable_scope): File variables point
1575 directly to the global_setlist variable. So, inserting a new
1576 scope in front of that has no effect on those variables: they
1577 don't go through current_variable_set_list. If we're pushing a
1578 scope and the current scope is global, push it "the other way" so
1579 that the new setlist is in the global_setlist variable, and
1580 next points to a new setlist with the global variable set.
1581 (pop_variable_scope): Properly undo a push with the new
1583 Fixes Savannah bug #11913.
1585 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1587 * job.c (reap_children): Don't die of the command failed but
1588 the dontcare flag is set. Fixes Savannah bug #13216.
1590 * implicit.c (pattern_search): When creating a target from
1591 an implicit rule match, lookup pattern target and set precious
1592 flag in a newly created target. Fixes Savannah bug #13218.
1594 2005-05-13 Paul D. Smith <psmith@gnu.org>
1596 Implement "if... else if... endif" syntax.
1598 * read.c (eval): Push all checks for conditional words ("ifeq",
1599 "else", etc.) down into the conditional_line() function.
1600 (conditional_line): Rework to allow "else if..." clause. New
1601 return value -2 for lines which are not conditionals. The
1602 ignoring flag can now also be 2, which means "already parsed a
1603 true branch". If that value is seen no other branch of this
1604 conditional can be considered true. In the else parsing if there
1605 is extra text after the else, invoke conditional_line()
1606 recursively to see if it's another conditional. If not, it's an
1607 error. If so, raise the conditional value to this level instead
1608 of creating a new conditional nesting level. Special check for
1609 "else" and "endif", which aren't allowed on the "else" line.
1610 * doc/make.texi (Conditional Syntax): Document the new syntax.
1612 2005-05-09 Paul D. Smith <psmith@gnu.org>
1614 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1615 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1616 recurses to the w32 directory, even on non-Windows systems. Use
1617 the method suggested in the automake manual.
1618 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1619 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1621 2005-05-07 Paul D. Smith <psmith@gnu.org>
1623 * main.c (die): If we're dying with a fatal error (not that a
1624 command has failed), write back any leftover tokens before we go.
1626 * job.c (set_child_handler_action_flags): If there are jobs
1627 waiting for the load to go down, set an alarm to go off in 1
1628 second. This allows us to wake up from a potentially long-lasting
1629 read() and start a new job if the load has gone down. Turn it off
1631 (job_noop): Dummy signal handler function.
1632 (new_job): Invoke it with the new semantics.
1634 * docs/make.texi: Document secondary expansion. Various cleanups
1637 2005-05-03 Paul D. Smith <psmith@gnu.org>
1639 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1640 the targets which are to ultimately be made are called "goals";
1641 see the GNU make manual. Also, MAKECMDGOALS, etc.
1643 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1644 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1645 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1647 2005-05-02 Paul D. Smith <psmith@gnu.org>
1649 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1650 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1651 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1652 functions to vmsjobs.c. #include it into jobs.c.
1654 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1655 jobserver tokens. I found that this happens when an exported
1656 recursive variable contains a $(shell ...) function reference: in
1657 this situation we could "forget" to write back a token.
1659 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1660 we have. It's not reliable to depend on the number of children in
1661 our linked list so keep a separate count.
1662 (new_job): Check jobserver_tokens rather than children &&
1663 waiting_jobs. Increment jobserver_tokens when we get one.
1664 (free_child): If jobserver_tokens is 0, internal error. If it's
1665 >1, write a token back to the jobserver pipe (we don't write a
1666 token for the "free" job). Decrement jobserver_tokens.
1668 * main.c: Add variable master_job_slots.
1669 (main): Set it to hold the number of jobs requested if we're the
1670 master process, when using the jobserver.
1671 (die): Sanity checks: first test jobserver_tokens to make sure
1672 this process isn't holding any tokens we didn't write back.
1673 Second, if master_job_slots is set count the tokens left in the
1674 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1676 2005-04-24 Paul D. Smith <psmith@gnu.org>
1678 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1679 with -l# can lose jobserver tokens, because waiting jobs are not
1680 consulted properly when checking for the "free" token.
1682 * job.c (free_child): Count waiting_jobs as having tokens.
1683 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1684 handle jobs waiting for the load to drop.
1686 2005-04-23 Paul D. Smith <psmith@gnu.org>
1688 * main.c (main): Be careful to not core if a variable setting in
1689 the environment doesn't contain an '='. This is illegal but can
1690 happen in broken setups.
1691 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1693 2005-04-12 Paul D. Smith <psmith@gnu.org>
1695 The second expansion feature causes significant slowdown. Timing
1696 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1697 read the makefile before the feature, to 11+s to do the same
1698 operations after the feature. Additionally, memory usage
1699 increased drastically. To fix this I added some intelligence that
1700 avoids the overhead of the second expansion unless it's required.
1702 * dep.h: Add a new boolean field, need_2nd_expansion.
1704 * read.c (eval): When creating the struct dep for the target,
1705 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1706 (record_files): If there's a "%" in a static pattern rule, it gets
1707 converted to "$*" so set need_2nd_expansion to 1.
1709 * file.c (expand_deps): Rework to be more efficient. Only perform
1710 initialize_file_variables(), set_file_variables(), and
1711 variable_expand_for_file() if the need_2nd_expansion is set.
1713 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1714 (pattern_search): Ditto.
1715 * main.c (handle_non_switch_argument): Ditto.
1717 * read.c (read_all_makefiles): Ditto.
1718 (eval_makefile): Ditto.
1720 2005-04-07 Paul D. Smith <psmith@gnu.org>
1722 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1723 * variable.c (sync_Path_environment): Ditto.
1724 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1726 * main.c (main): Define the .FEATURES variable.
1727 * NEWS: Announce .FEATURES.
1728 * doc/make.texi (Special Variables): Document .FEATURES.
1730 * remake.c (check_dep): If a file is .PHONY, update it even if
1731 it's marked intermediate. Fixes Savannah bug #12331.
1733 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1735 * file.c (expand_deps): Factor out the second expansion and
1736 prerequisite line parsing logic from snap_deps().
1738 * file.c (snap_deps): Use expand_deps(). Expand and parse
1739 prerequisites of the .SUFFIXES special target first. Fixes
1740 Savannah bug #12320.
1742 2005-03-13 Paul D. Smith <psmith@gnu.org>
1744 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1747 2005-03-11 Paul D. Smith <psmith@gnu.org>
1749 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1750 available, not undefined (from Earnie Boyd).
1752 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1754 * implicit.c (pattern_search): Mark an intermediate target as
1755 precious if it happened to be a prerequisite of some (other)
1756 target. Fixes Savannah bug #12267.
1758 2005-03-09 Paul D. Smith <psmith@gnu.org>
1760 * read.c (eval_makefile): Add alloca(0).
1761 (eval_buffer): Ditto.
1763 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1765 * main.c (main): Use o_file instead of o_default when defining
1766 the .DEFAULT_TARGET special variable.
1767 * read.c (eval): Use define_variable_global() instead of
1768 define_variable() when setting new value for the .DEFAULT_TARGET
1769 special variable. Fixes Savannah bug #12266.
1771 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1773 * imlicit.c (pattern_search): Mark files for which an implicit
1774 rule has been found as targets. Fixes Savannah bug #12202.
1776 2005-03-04 Paul D. Smith <psmith@gnu.org>
1779 * doc/make.texi (Automatic Variables): Document $|.
1781 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1783 * read.c (record_files): Instead of substituting % with
1784 actual stem value in dependency list replace it with $*.
1785 This fixes stem triple expansion bug.
1787 * implicit.c (pattern_search): Copy stem to a separate
1788 buffer and make it a properly terminated string. Assign
1789 this buffer instead of STEM (which is not terminated) to
1790 f->stem. Instead of substituting % with actual stem value
1791 in dependency list replace it with $*. This fixes stem
1792 triple expansion bug.
1794 2005-03-01 Paul D. Smith <psmith@gnu.org>
1796 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1797 on Windows, as it takes a handle not a pid. Just exit.
1798 Fix from patch #3679, provided by Alessandro Vesely.
1800 * configure.in: Update check for sys_siglist[] from autoconf manual.
1801 * signame.c (strsignal): Update to use the new autoconf macro.
1803 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1805 * read.c (record_files): Add a check for the list of prerequisites
1806 of a static pattern rule being empty. Fixes Savannah bug #12180.
1808 2005-02-28 Paul D. Smith <psmith@gnu.org>
1810 * doc/make.texi (Text Functions): Update docs to allow the end
1811 ordinal for $(wordlist ...) to be 0.
1812 * function.c (func_wordlist): Fail if the start ordinal for
1813 $(wordlist ...) is <1. Matches documentation.
1814 Resolves Savannah support request #103195.
1816 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1817 previously we were stopping when !-q, exactly the opposite. This
1818 has been wrong since version 1.34, in 1994!
1819 (update_file): If we got an error don't break out to run more
1820 double-colon rules: just return immediately.
1821 Fixes Savannah bug #7144.
1823 2005-02-27 Paul D. Smith <psmith@gnu.org>
1825 * misc.c (end_of_token): Make argument const.
1826 * make.h: Update prototype.
1828 * function.c (abspath, func_realpath, func_abspath): Use
1829 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1830 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1831 * read.c (record_files): Ditto.
1832 * variable.c (do_variable_definition): Ditto.
1834 * function.c (func_error): Create a new function $(info ...) that
1835 simply prints the message to stdout with no extras.
1836 (function_table_init): Add new function to the table.
1837 * NEWS: Add $(info ...) reference.
1838 * doc/make.texi (Make Control Functions): Document it.
1840 New feature: if the system supports symbolic links, and the user
1841 provides the -L/--check-symlink-time flag, then use the latest
1842 mtime between the symlink(s) and the target file.
1844 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1845 readlink(). If both are available, define MAKE_SYMLINKS.
1846 * main.c: New variable: check_symlink_flag.
1847 (usage): Add a line for -L/--check-symlink-times to the help string.
1848 (switches): Add -L/--check-symlink-times command line argument.
1849 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1850 print a warning and disable it again.
1851 * make.h: Declare check_symlink_flag.
1852 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1853 if the file is a symlink then check each link in the chain and
1854 choose the NEWEST mtime we find as the mtime for the file. The
1855 newest mtime might be the file itself!
1856 * NEWS: Add information about this new feature.
1857 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1859 Avoid core dumps described in Savannah bug # 12124:
1861 * file.c: New variable snapped_deps remember whether we've run
1863 (snap_deps): Set it.
1864 * filedef.h: Extern it.
1865 * read.c (record_files): Check snapped_deps; if it's set then
1866 we're trying to eval a new target/prerequisite relationship from
1867 within a command script, which we don't support. Fatal.
1869 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1871 Implementation of the .DEFAULT_TARGET special variable.
1873 * read.c (eval): If necessary, update default_target_name when
1875 * read.c (record_files): Update default_target_file if
1876 default_target_name has changed.
1877 * main.c (default_target_name): Define.
1878 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1879 default_target_name is set use default_target_file as a root
1881 * filedef.h (default_target_name): Declare.
1882 * dep.h (free_dep_chain):
1883 * misc.c (free_dep_chain): Change to operate on struct nameseq
1884 and change name to free_ns_chain.
1885 * file.c (snap_deps): Update to use free_ns_chain.
1887 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1889 Implementation of the second expansion in explicit rules,
1890 static pattern rules and implicit rules.
1892 * read.c (eval): Refrain from chopping up rule's dependencies.
1893 Store them in a struct dep as a single dependency line. Remove
1894 the code that implements SySV-style automatic variables.
1896 * read.c (record_files): Adjust the code that handles static
1897 pattern rules to expand all percents instead of only the first
1898 one. Reverse the order in which dependencies are stored so that
1899 when the second expansion reverses them again they appear in
1900 the makefile order (with some exceptions, see comments in
1901 the code). Remove the code that implements SySV-style automatic
1904 * file.c (snap_deps): Implement the second expansion and chopping
1905 of dependency lines for explicit rules.
1907 * implicit.c (struct idep): Define an auxiliary data type to hold
1908 implicit rule's dependencies after stem substitution and
1911 * implicit.c (free_idep_chain): Implement.
1913 * implicit.c (get_next_word): Implement helper function for
1914 parsing implicit rule's dependency lines into words taking
1915 into account variable expansion requests. Used in the stem
1918 * implicit.c (pattern_search): Implement the second expansion
1919 for implicit rules. Also fixes bug #12091.
1921 * commands.h (set_file_variables): Declare.
1922 * commands.c (set_file_variables): Remove static specifier.
1924 * dep.h (free_dep_chain): Declare.
1925 * misc.c (free_dep_chain): Implement.
1927 * variable.h (variable_expand_for_file): Declare.
1928 * expand.c (variable_expand_for_file): Remove static specifier.
1930 * make.h (strip_whitespace): Declare.
1931 * function.c (strip_whitespace): Remove static specifier.
1933 2005-02-26 Paul D. Smith <psmith@gnu.org>
1935 * main.c (main): Check for ferror() when reading makefiles from stdin.
1936 Apparently some shells in Windows don't close pipes properly and
1939 2005-02-24 Jonathan Grant <jg@jguk.org>
1941 * configure.in: Add MinGW configuration options, and extra w32 code
1943 * Makefile.am: Add MinGW configuration options, and extra w32 code
1945 * main.c: Determine correct program string (after last \ without .exe).
1946 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1948 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1949 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1950 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1951 environment support.
1953 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1955 * function.c (func_shell): When initializing error_prefix, check
1956 that reading file name is not null. This fixes long-standing
1957 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1959 2005-02-09 Paul D. Smith <psmith@gnu.org>
1961 * maintMakefile: Update the CVS download URL to simplify them.
1962 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1963 downloading the .texi files from Savannah now.
1965 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1967 * main.c (handle_non_switch_argument): Only add variables to
1968 command_variables if they're not already there: duplicate settings
1969 waste space and can be confusing to read.
1971 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1972 this header is never included by non-WINDOWS32 code, and it
1973 requires <config.h> to define which isn't always included first.
1975 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1976 testing MINGW32 versions.
1978 * main.c (log_working_directory): flush stdout to be sure the WD
1979 change is printed before any stderr messages show up.
1981 2005-02-01 Paul D. Smith <psmith@gnu.org>
1983 * maintMakefile (po_repo): Update the GNU translation site URL.
1985 2004-12-01 Paul D. Smith <psmith@gnu.org>
1987 * main.c (main): Change char* env_shell to struct variable shell_var.
1988 * variable.c (target_environment): Use new shell_var.
1990 2004-11-30 Paul D. Smith <psmith@gnu.org>
1992 * configure.in: The old way we avoided creating build.sh from
1993 build.sh.in before build.sh.in exists doesn't work anymore; we
1994 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1995 the help!). This also keeps automake from complaining.
1996 * Makefile.am (README): Add a dummy target so automake won't
1997 complain that this file doesn't exist when we checkout from CVS.
1998 * maintMakefile (.dep_segment): Rewrite this rule since newer
1999 versions of automake don't provide DEP_FILES.
2001 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2003 Implementation of `realpath' and `abspath' built-in functions.
2005 * configure.in: Check for realpath.
2006 * function.c (abspath): Return an absolute file name that does
2007 not contain any `.' or `..' components, nor repeated `/'.
2008 * function.c (func_abspath): For each name call abspath.
2009 * function.c (func_realpath): For each name call realpath
2010 from libc or delegate to abspath if realpath is not available.
2011 * doc/make.texi (Functions for File Names): Document new functions.
2012 * doc/make.texi (Quick Reference): Ditto.
2014 2004-11-28 Paul D. Smith <psmith@gnu.org>
2016 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2017 arguments. Fixes bug #10252.
2019 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2021 * main.c (main): Set SHELL to v_noexport by default. Remember the
2022 original environment setting of SHELL in the env_shell variable.
2023 * main.h: Export new env_shell variable.
2024 * variable.c (target_environment): If we find a v_noexport
2025 variable for SHELL, add a SHELL variable with the env_shell value.
2026 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2027 * doc/make.texi (Variables/Recursion): Ditto.
2029 2004-11-28 Paul D. Smith <psmith@gnu.org>
2031 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2032 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2033 Patch by Alessandro Vesely.
2035 2004-11-12 Paul D. Smith <psmith@gnu.org>
2037 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2038 the command line if it's inside a string.
2039 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2041 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2043 * function.c (func_lastword): New function: return last word
2044 from the list of words.
2045 * doc/make.texi: Document $(lastword ). Fix broken links in
2046 Quick Reference section.
2048 2004-10-06 Paul D. Smith <psmith@gnu.org>
2050 Apply patch from Alessandro Vesely, provided with bug # 9748.
2051 Fix use of tmpnam() to work with Borland C.
2053 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2054 construction of a temporary filename, and call new function
2055 create_batch_filename().
2056 (create_batch_filename) [WINDOWS32]: New function to create a
2059 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2061 * read.c (record_target_var): Expand simple pattern-specific
2063 * variable.c (initialize_file_variables): Do not expand simple
2064 pattern-specific variable.
2066 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2068 * remake.c (update_file_1): When rebuilding makefiles inherit
2069 dontcare flag from a target that triggered update.
2071 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2073 * variable.c (initialize_file_variables): Mark pattern-specific
2074 variable as a per-target and copy export status.
2076 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2078 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2080 * implicit.c (pattern_search): When considering an implicit rule's
2081 prerequisite check that it is actually a target rather then
2082 just an entry in the file hashtable.
2084 2004-09-21 Paul D. Smith <psmith@gnu.org>
2086 * read.c (readstring): Fix some logic errors in backslash handling.
2087 (eval): Remove some unnecessary processing in buffer handling.
2088 (record_target_var): Assert that parse_variable_definition() succeeded.
2089 Reported by: Markus Mauhart <qwe123@chello.at>.
2091 * misc.c: Removed the sindex() function. All instances of this
2092 function were trivially replaceable by the standard strstr()
2093 function, and that function will always have better (or certainly
2094 no worse) performance than the very simple-minded algorithm
2095 sindex() used. This can matter with complex makefiles.
2096 * make.h: Remove the prototype for sindex().
2097 * function.c (subst_expand): Convert sindex() call to strstr().
2098 This means we no longer need to track the TLEN value so remove that.
2099 (func_findstring): Convert sindex() to strstr().
2100 * commands.c (chop_commands): Convert sindex() calls to strstr().
2101 Suggested by: Markus Mauhart <qwe123@chello.at>.
2103 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2104 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2105 If SHELL is set to CMD.EXE then assume it's batch-mode and
2106 non-unixy. I wrote the code differently from the patch, though,
2107 to make it safer. This also resolves bug #9174.
2109 2004-09-20 Paul D. Smith <psmith@gnu.org>
2111 * expand.c (variable_expand_string): Modify to invoke
2112 patsubst_expand() instead of subst_expand(); the latter didn't
2113 handle suffix patterns correctly.
2114 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2115 was used only from variable_expand_string() and is no longer used
2117 (func_subst): Ditto, on call to subst_expand().
2118 (patsubst_expand): Require the percent pointers to point to the
2119 character after the %, not to the % itself.
2120 * read.c (record_files): New call criteria for patsubst_expand().
2121 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2122 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2124 2004-09-19 Paul D. Smith <psmith@gnu.org>
2126 * function.c (subst_expand): Fix a check in by_word: look for a
2127 previous blank if we're beyond the beginning of the string, not
2128 the beginning of the word.
2129 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2131 2004-05-16 Paul D. Smith <psmith@gnu.org>
2133 * remake.c (update_goal_chain): Change the argument specifying
2134 whether we're rebuilding makefiles to be a global variable,
2135 REBUILDING_MAKEFILES.
2136 (complain): Extract the code that complains about no rules to make
2137 a target into a separate function.
2138 (update_file_1): If we tried to rebuild a file during the makefile
2139 rebuild phase and it was dontcare, then no message was printed.
2140 If we then try to build the same file during the normal build,
2141 print a message this time.
2142 (remake_file): Don't complain about un-remake-able files when
2143 we're rebuilding makefiles.
2145 2004-05-11 Paul D. Smith <psmith@gnu.org>
2147 * job.c (construct_command_argv_internal): OS/2 patches from
2148 Andreas Buening <andreas.buening@nexgo.de>.
2150 2004-05-10 Paul D. Smith <psmith@gnu.org>
2152 * remake.c (update_file): Don't walk the double-colon chain unless
2153 this is a double-colon rule. Fix suggested by Boris Kolpackov
2154 <boris@kolpackov.net>.
2156 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2157 * readme.vms: New section describing OpenVMS support and issues.
2158 * default.c (default_variables): Add support for IA64.
2159 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2160 without some privilege aborts make with the error
2161 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2162 pressing Ctrl+Y and the input device is no terminal. The change
2163 catches this error and just continues.
2165 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2167 2004-04-25 Paul D. Smith <psmith@gnu.org>
2169 * commands.c (set_file_variables): Set $< properly in the face of
2170 order-only prerequisites.
2171 Patch from Boris Kolpackov <boris@kolpackov.net>
2173 2004-04-21 Bob Byrnes <byrnes@curl.com>
2175 * main.c (main): Notice failures to remake makefiles.
2177 2004-03-28 Paul D. Smith <psmith@gnu.org>
2179 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2181 * job.c: No default shell for RISC OS.
2182 (load_too_high): Hard-code the return to 1.
2183 (construct_command_argv_internal): No sh_chars or sh_cmds.
2184 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2186 2004-03-20 Paul D. Smith <psmith@gnu.org>
2188 * variable.c (do_variable_definition): Don't append from the
2189 global set if a previous non-appending target-specific variable
2190 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2193 * expand.c (reference_variable): Don't give up on variables with
2194 no value that have the target-specific append flag set: they might
2195 have a value after all. Reported by Oliver Schmidt
2196 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2197 <nikulin@dx1cmd.inp.nsk.su>.
2199 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2200 refer to absolute pathnames in directories that don't exist: some
2201 portion of the makefile could create those directories before we
2202 match the pattern. Fixes bugs #775 and #108.
2204 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2206 * main.c (main): Free makefile_mtimes if we have any.
2207 * README.W32.template: Update documentation for the current status
2208 of the MS-Windows port.
2209 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2210 environment variable is sometimes already defined which causes the
2212 * main.c (debug_signal_handler): Only define this function if
2213 SIGUSR1 is available.
2215 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2217 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2218 * README.OS2.template: Documentation updates.
2219 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2220 link line for safety.
2221 * maintMakefile (build.sh.in): Remove an extraneous ")".
2222 * job.c (child_execute_job): Close saved FDs.
2223 * job.c (exec_command) [OS/2]: exec_command(): If the command
2224 can't be exec'ed and if the shell is not Unix-sh, then try again
2225 with argv = { "cmd", "/c", ... }. Normally, this code is never
2226 reached for the cmd shell unless the command really doesn't exist.
2227 (construct_command_argv_internal) [OS/2]: The code for cmd
2228 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2229 The CMD builtin commands are case insensitive so use strcasecmp().
2231 2004-03-19 Paul D. Smith <psmith@gnu.org>
2233 * read.c (do_define): Re-order line counter increment so the count
2234 is accurate (we were losing one line per define). Reported by
2235 Dave Yost <Dave@Yost.com>.
2237 2004-03-06 Paul D. Smith <psmith@gnu.org>
2239 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2241 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2242 * misc.c (message,error,fatal): Ditto.
2243 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2244 * config.h.W32.template: Ditto.
2245 * config.h-vms.template: Ditto.
2246 * config.ami.template: Ditto.
2248 2004-03-04 Paul D. Smith <psmith@gnu.org>
2250 * README.template: Add a note about broken /bin/sh on SunOS
2251 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2253 * misc.c (message, error, fatal): Don't use "..." if we're using
2254 varargs. ansi2knr should handle this but it doesn't work: it
2255 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2256 done. On many systems (SunOS for example) va_dcl is a #define.
2257 So, force the use of the non-"..." version on pre-ANSI compilers.
2259 * maintMakefile (sign-dist): Create some rules to help automate
2260 the new GNU ftp upload method.
2262 2004-02-24 Paul D. Smith <psmith@gnu.org>
2264 * config.h.W32.template: Add HAVE_STDARG_H
2265 * config.h-vms.template: Ditto.
2266 * config.ami.template: Ditto.
2268 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2270 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2271 * build_w32.bat: Remove extra "+".
2273 2004-02-23 Paul D. Smith <psmith@gnu.org>
2275 * make.h: Create an UNUSED macro to mark unused parameters.
2276 * (many): Clean up warnings by applying UNUSED, fixing
2277 signed/unsigned incompatibilities, etc.
2279 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2281 * filedef.h: Name the command_state enumeration.
2282 * file.c (set_command_state): Use the enumeration in the function
2285 * configure.in: Explicitly set SET_MAKE to empty, to disable
2286 MAKE=make even when no make already exists. Fix bug #3823.
2288 2004-02-22 Paul D. Smith <psmith@gnu.org>
2290 * maintMakefile: Perl script to clean up all non-CVS files. Use
2291 it on all the subdirectories for the cvs-clean target.
2293 * main.c (decode_switches): Require non-empty strings for all our
2294 string command-line options. Fixes Debian bug # 164165.
2296 * configure.in: Check for stdarg.h and varargs.h.
2297 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2298 for printing messages.
2299 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2304 A number of patches for OS/2 support from Andreas Buening
2305 <andreas.buening@nexgo.de>:
2307 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2308 disable the SIGCHLD handler.
2309 (reap_children) [OS/2]: Remove special handling of job_rfd.
2310 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2311 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2312 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2313 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2314 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2317 2004-02-21 Paul D. Smith <psmith@gnu.org>
2319 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2320 <mail@kristov.de> reports that if process_begin() fails we don't
2321 handle the error condition correctly in all cases.
2322 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2323 to have a newline on the message.
2325 * job.c (construct_command_argv_internal): Add "test" to UNIX
2326 sh_cmds[]. Fixes Savannah bug # 7606.
2328 2004-02-04 Paul D. Smith <psmith@gnu.org>
2330 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2331 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2332 Hartmut Becker <Hartmut.Becker@hp.com>.
2334 2004-01-21 Paul D. Smith <psmith@gnu.org>
2336 * job.c (load_too_high): Implement an algorithm to control the
2337 "thundering herd" problem when using -l to control job creation
2338 via the load average. The system only recomputes the load once a
2339 second but we can start many jobs in a second. To solve this we
2340 keep track of the number of jobs started in the last second and
2341 apply a weight to try to guess what a correct load would be.
2342 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2343 Also fixes bug #4693.
2344 (reap_children): Decrease the job count for this second.
2345 (start_job_command): Increase the job count for this second.
2347 * read.c (conditional_line): Expand the text after ifn?def before
2348 checking to see if it's a single word. Fixes bug #7257.
2350 2004-01-09 Paul D. Smith <psmith@gnu.org>
2352 * file.c (print_file): Recurse to print all targets in
2353 double-colon rules. Fixes bug #4518, reported (with patch) by
2354 Andrew Chatham <chatham@google.com>.
2356 2004-01-07 Paul D. Smith <psmith@gnu.org>
2358 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2359 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2360 AC_FUNC_SETVBUF_REVERSED.
2362 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2363 (MAKE Variable): Fix Savannah bug #4898.
2365 * job.c (construct_command_argv_internal): Add "!" to the list of
2366 shell escape chars. POSIX sh allows it to appear before a
2367 command, to negate the exit code. Fixes bug #6404.
2369 * implicit.c (pattern_search): When matching an implicit rule,
2370 remember which dependencies have the ignore_mtime flag set.
2371 Original fix provided in Savannah patch #2349, by Benoit
2372 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2374 2003-11-22 Paul D. Smith <psmith@gnu.org>
2376 * README.W32.template (Outputs): Clarification on -j with
2377 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2380 2003-11-02 Paul D. Smith <psmith@gnu.org>
2382 * function.c (func_if): Strip all the trailing whitespace from the
2383 condition, then don't expand it. Fixed bug # 5798.
2385 * expand.c (recursively_expand_for_file): If we're expanding a
2386 variable with no file context, then use the variable's context.
2389 2003-10-21 Paul D. Smith <psmith@gnu.org>
2391 * main.c (log_working_directory): Add newlines to printf()s.
2393 * README.cvs: Add a note to ignore warnings during autoreconf.
2395 * maintMakefile (po_repo): Set a new URL for PO file updates.
2396 (get-config/config.guess get-config/config.sub): Get these files
2397 from the Savannah config project instead of ftp.gnu.org.
2399 2003-10-05 Paul Eggert <eggert@twinsun.com>
2401 * main.c (main): Avoid potential subscript error if environ has
2404 2003-08-22 Paul D. Smith <psmith@gnu.org>
2406 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2407 systems which don't yet implement the C89 standard :-/.
2409 2003-07-18 Paul D. Smith <psmith@gnu.org>
2411 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2412 [WINDOWS32]: Initialize hash.
2414 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2416 * dir.c (read_dirstream): Provide a workaround for broken versions of
2417 the MinGW dirent structure.
2419 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2421 * w32/include/dirent.h: Add __MINGW32__ filter.
2423 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2425 * make.h: Add global declaration of *make_host.
2426 * main.c (print_usage): Remove local declaration of *make_host.
2427 (print_version): Display "This program built for ..." after Copyright
2430 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2432 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2433 execution of "makeinfo --html make.texi".
2435 2003-04-30 Paul D. Smith <psmith@gnu.org>
2437 * build.template: Make some changes to maybe allow this script to
2438 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2440 * README.OS2.template: New file for OS/2 support. Original
2441 contributed by Andreas Buening.
2442 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2445 2003-04-19 Paul D. Smith <psmith@gnu.org>
2447 Fix bug #1405: allow a target to match multiple pattern-specific
2450 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2451 variable.c, where they've always belonged.
2452 * rule.h: Move the prototypes and struct pattern_var as well.
2453 * variable.c (initialize_file_variables): Invoke
2454 lookup_pattern_var() in a loop, until no more matches are found.
2455 If a match is found, create a new variable set for the target's
2456 pattern variables. Then merge the contents of each matching
2457 pattern variable set into the target's pattern variable set.
2458 (lookup_pattern_var): Change this function to be usable
2459 in a loop. It takes a starting position: if NULL, start at the
2460 beginning; if non-NULL, start with the pattern variable after that
2461 position, and return the next matching pattern.
2462 (create_pattern_var): Create a unique instance of
2463 pattern-specific variables for every definition in the makefile.
2464 Don't combine the same pattern together. This allows us to
2465 process the variable handling properly even when the same pattern
2466 is used multiple times.
2467 (parse_variable_definition): New function: break out the parsing
2468 of a variable definition line from try_variable_definition.
2469 (try_variable_definition): Call parse_variable_definition to
2471 (print_variable_data_base): Print out pattern-specific variables.
2472 * variable.h (struct variable): Remember when a variable is
2473 conditional. Also remember its flavor.
2474 (struct pattern_var): Instead of keeping a variable set, we just
2475 keep a single variable for each pattern.
2476 * read.c (record_target_var): Each pattern variable contains only a
2477 single variable, not a set, so create it properly.
2478 * doc/make.texi (Pattern-specific): Document the new behavior.
2480 2003-04-17 Paul D. Smith <psmith@gnu.org>
2482 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2483 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2484 file/directory naming rules for VMS so I can't tell whether this
2487 2003-04-09 Paul D. Smith <psmith@gnu.org>
2489 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2490 DOS-style pathnames: backslash separators and drive specifiers.
2492 2003-03-28 Paul D. Smith <psmith@gnu.org>
2494 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2495 the intermediate flag on all targets. Fixes bug #2515.
2497 2003-03-24 Paul D. Smith <psmith@gnu.org>
2499 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2500 Upgrade to autoconf 2.57 and automake 1.7.3.
2502 * job.c: More OS/2 changes from Andreas Buening.
2504 * file.c (print_file): Fix variable initialization.
2507 * remake.c (notice_finished_file):
2509 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2510 some calls (like readdir()) return NULL in valid situations
2511 without resetting errno. Fixes bug #2846.
2513 2003-02-25 Paul D. Smith <psmith@gnu.org>
2515 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2517 * job.c (_is_unixy_shell) [OS/2]: New function.
2518 Set default shell to /bin/sh.
2519 (reap_children): Close the job_rfd pipe here since we don't use a
2521 (set_child_handler_action_flags): define this to empty on OS/2.
2522 (start_job_command): Close the jobserver pipe and use
2523 child_execute_job() instead of fork/exec.
2524 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2525 rather than exec'ing, then reconfigure stdin/stdout.
2526 (exec_command): Rewrite to use spawn instead of exec. Return the
2529 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2530 in DOS. Handle the TEMP environment variable as in DOS. Don't
2531 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2532 use -j in DOS mode. Use child_execute_job() instead of
2535 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2538 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2539 prototypes that return values.
2541 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2543 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2544 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2546 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2549 2003-02-24 Paul D. Smith <psmith@gnu.org>
2551 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2552 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2553 (child_execute_job) [VMS]: Handle error status properly.
2554 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2556 * function.c (func_shell): Use EINTRLOOP() while reading from the
2557 subshell pipe (Fixes bug #2502).
2558 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2560 * main.c (main): Ditto.
2562 2003-01-30 Paul D. Smith <psmith@gnu.org>
2564 * read.c (eval): eval() was not fully reentrant, because the
2565 collapsed buffer was static. Change it to be an automatic
2566 variable so that eval() can be invoked recursively.
2568 (eval): Apply patch # 1022: fix memory reference error on long
2569 target-specific variable lines.
2570 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2572 * function.c (check_numeric): Combine the is_numeric() function
2573 into this function, since it's only called from one place.
2574 Constify this function. Have it print the incorrect string in the
2575 error message. Fixes bug #2407.
2576 (strip_whitespace): Constify.
2577 (func_if): Constify.
2578 * expand.c (expand_argument): Constify.
2580 2003-01-29 Paul D. Smith <psmith@gnu.org>
2582 Fix bug # 2169, also reported by other people on various systems.
2584 * make.h: Some systems, such as Solaris and PTX, do not fully
2585 implement POSIX-compliant SA_RESTART functionality; important
2586 system calls like stat() and readdir() can still fail with EINTR
2587 even if SA_RESTART has been set on the signal handler. So,
2588 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2589 EINTR for system calls which return -1 or 0 (NULL), respectively,
2591 Also, remove the old atomic_stat()/atomic_readdir() and
2592 HAVE_BROKEN_RESTART handling.
2594 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2596 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2597 * remake.c (touch_file): Ditto.
2599 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2600 * read.c (construct_include_path): Ditto.
2601 * remake.c (name_mtime): Ditto.
2602 * vpath.c (selective_vpath_search): Ditto.
2603 * dir.c (find_directory): Ditto.
2604 (local_stat): Ditto.
2605 (find_directory): Use ENULLLOOP() to wrap opendir().
2606 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2608 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2609 atomic_readdir() handling.
2611 2003-01-22 Paul D. Smith <psmith@gnu.org>
2613 * function.c (func_call): Fix Bug #1744. If we're inside a
2614 recursive invocation of $(call ...), mask any of the outer
2615 invocation's arguments that aren't used by this one, so that this
2616 invocation doesn't "inherit" them accidentally.
2618 2002-12-05 Paul D. Smith <psmith@gnu.org>
2620 * function.c (subst_expand): Valery Khamenia reported a
2621 pathological performance hit when doing substitutions on very
2622 large values with lots of words: turns out we were invoking
2623 strlen() a ridiculous number of times. Instead of having each
2624 call to sindex() call strlen() again, keep track of how much of
2625 the text we've seen and pass the length to sindex().
2627 2002-11-19 Paul D. Smith <psmith@gnu.org>
2629 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2632 2002-11-16 Paul D. Smith <psmith@gnu.org>
2634 * NMakefile.template (OBJS): Add hash.c object file.
2635 * SMakefile.template (srcs): Ditto.
2636 * Makefile.ami (objs): Ditto.
2637 * build_w32.bat: Ditto.
2639 * Makefile.DOS.template: Remove extra dependencies.
2641 2002-10-25 Paul D. Smith <psmith@gnu.org>
2643 * expand.c (install_variable_buffer): New function. Install a new
2644 variable_buffer context and return the previous one.
2645 (restore_variable_buffer): New function. Free the current
2646 variable_buffer context and put a previously saved one back.
2647 * variable.h: Prototypes for {install,restore}_variable_buffer.
2648 * function.c (func_eval): Push a new variable_buffer context
2649 before we eval, then restore the old one when we're done.
2652 * read.c (install_conditionals): New function. Install a new
2653 conditional context and return the previous one.
2654 (restore_conditionals): New function. Free the current
2655 conditional context and put a previously saved one back.
2656 (eval): Use the {install,restore}_conditionals for "include"
2658 (eval_buffer): Use {install,restore}_conditionals to preserve the
2659 present conditional state before we evaluate the buffer.
2662 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2664 (Recursion): Add a variable index entry for CURDIR.
2666 * README.cvs: Update to appropriate versions.
2667 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2668 don't need to copy loadavg.c: automake is smart enough to create
2669 it for me. Still have a bug in automake related to ansi2knr tho.
2671 2002-10-14 Paul D. Smith <psmith@gnu.org>
2673 * remake.c (notice_finished_file): Only touch targets if they have
2674 at least one command (as per POSIX). Resolve Bug #1418.
2676 * *.c: Convert to using ANSI C-style function definitions.
2677 * Makefile.am: Enable the ansi2knr feature of automake.
2678 * configure.in: ditto.
2680 2002-10-13 Paul D. Smith <psmith@gnu.org>
2682 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2683 for automatic variable values like $^, etc. In the case of very
2684 large lists of prerequisites this causes problems. Instead reuse
2685 a static buffer (resizeable) for each variable.
2687 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2688 target-specific variable definitions. Check for it and set an
2690 (record_target_var): Set the export field to v_export if the
2691 "exported" flag is set.
2692 * doc/make.texi (Target-specific): Document the ability to use
2695 * doc/make.texi: Change the name of the section on automatic
2696 variables from "Automatic" to "Automatic Variables". Added text
2697 clarifying the scope of automatic variables.
2699 2002-10-04 Paul D. Smith <psmith@gnu.org>
2701 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2703 (record_files): Ditto.
2705 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2706 the search for the '=' to only within the enclosing parens.
2708 2002-10-03 Paul D. Smith <psmith@gnu.org>
2710 Version 3.80 released.
2712 * dir.c: Change hash functions to use K&R function definition style.
2713 * function.c: Ditto.
2715 * variable.c: Ditto.
2717 Update to automake 1.7.
2719 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2720 (pdf): Remove this target as automake now provides one.
2722 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2724 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2726 * makefile.com: Updates for GNU make 3.80.
2727 * makefile.vms: Ditto.
2729 2002-09-23 Paul D. Smith <psmith@gnu.org>
2731 * read.c (enum make_word_type): Remove w_comment.
2732 (get_next_mword): Don't treat comment characters as special; where
2733 this function is used we will never see a comment (it's stripped
2734 before we get here) and treating comments specially means that
2735 targets like "foo\#bar" aren't handled properly.
2737 2002-09-18 Paul D. Smith <psmith@gnu.org>
2739 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2741 * read.c (eval): Expansion of arguments to export/unexport was
2742 ignoring all arguments after the first one. Change the algorithm
2743 to expand the whole line once, then parse the results.
2745 2002-09-17 Paul D. Smith <psmith@gnu.org>
2747 Fix Bug #940 (plus another bug I found while looking at this):
2749 * read.c (record_target_var): enter_file() will add a new entry if
2750 it's a double-colon target: we don't want to do that in this
2751 situation. Invoke lookup_file() and only enter_file() if it does
2752 not already exist. If the file we get back is a double-colon then
2753 add this variable to the "root" double-colon target.
2755 * variable.c (initialize_file_variables): If this file is a
2756 double-colon target but is not the "root" target, then initialize
2757 the root and make the root's variable list the parent of our
2760 2002-09-13 Paul D. Smith <psmith@gnu.org>
2762 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2764 * hash.c (round_up_2): Get rid of a warning.
2766 2002-09-12 Paul D. Smith <psmith@gnu.org>
2768 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2769 so it doesn't complain about getloadavg.c.
2771 * commands.c (set_file_variables): Make sure we always alloca() at
2772 least 1 character for the value of $? (for '\0').
2774 2002-09-11 Paul D. Smith <psmith@gnu.org>
2776 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2777 macro to use RESULT instead of the incorrect _RESULT_.
2779 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2780 and atomic_readdir(). We need to #include dirent.h to get this to
2782 * misc.c (atomic_readdir): Fix typos.
2784 2002-09-10 Paul D. Smith <psmith@gnu.org>
2786 * read.c (eval): Expand variable lists given to export and
2787 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2788 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2790 * doc/make.texi (Variables/Recursion): Document this.
2791 (Conditional Syntax): And here.
2793 2002-09-09 Paul D. Smith <psmith@gnu.org>
2795 * configure.in: Check for memmove().
2797 2002-09-07 Paul D. Smith <psmith@gnu.org>
2799 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2800 Michael Sterrett <msterret@coat.com> reports that while it has
2801 SA_RESTART, it does not work properly.
2803 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2804 that invokes stat() and loops to do it again if it returns EINTR.
2805 (atomic_readdir): Ditto, with readdir().
2807 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2808 and readdir() to atomic_stat() and atomic_readdir().
2810 2002-09-04 Paul D. Smith <psmith@gnu.org>
2812 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2813 reports that GNU make sometimes doesn't recognize that targets can
2814 be made, when directories can be created as prerequisites. He
2815 reports that changing the order of predicates in the DEP->changed
2816 flag test so that lookup_file() is always performed, solves this
2819 2002-08-08 Paul D. Smith <psmith@gnu.org>
2821 * configure.in: Require a newer version of gettext.
2823 * misc.c (perror_with_name): Translate the format string (for
2824 right-to-left language support).
2825 (pfatal_with_name): Ditto.
2827 * main.c: Create a static array of strings to store the usage
2828 text. This is done to facilitate translations.
2829 (struct command_switch): Remove argdesc and description fields.
2830 (switches): Remove values for obsolete fields.
2831 (print_usage): Print each element of the usage array.
2833 * hash.c: Change function definitions to be K&R style.
2835 2002-08-02 Paul D. Smith <psmith@gnu.org>
2837 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2838 this one because it's too hard to get right. We'll look at it for
2840 * main.c (main): Don't create the .TARGETS variable.
2841 * variable.c (handle_special_var): Don't handle .TARGETS.
2843 2002-08-01 Paul D. Smith <psmith@gnu.org>
2845 * main.c (switches): Add a new option, -B (--always-make). If
2846 specified, make will rebuild all targets that it encounters even
2847 if they don't appear to be out of date.
2848 (always_make_flag): New flag.
2849 * make.h: Extern always_make_flag.
2850 * remake.c (update_file_1): Check always_make_flag; if it's set we
2851 will always rebuild any target we can, even if none of its
2852 prerequisites are newer.
2855 * doc/make.texi (Shell Function): Make it clear that make
2856 variables marked as "export" are not passed to instances of the
2859 Add new introspection variable .VARIABLES and .TARGETS.
2861 * variable.c (handle_special_var): New function. If the variable
2862 reference passed in is "special" (.VARIABLES or .TARGETS),
2863 calculate the new value if necessary. .VARIABLES is handled here:
2864 walk through the hash of defined variables and construct a value
2865 which is a list of the names. .TARGETS is handled by
2866 build_target_list().
2867 (lookup_variable): Invoke handle_special_var().
2868 * file.c (build_target_list): Walk through the hask of known files
2869 and construct a list of the names of all the ones marked as
2871 * main.c (main): Initialize them to empty (and as simple variables).
2872 * doc/make.texi (Special Variables): Document them.
2873 * NEWS: Mention them.
2875 * variable.h (struct variable): Add a new flag "exportable" which
2876 is true if the variable name is valid for export.
2877 * variable.c (define_variable_in_set): Set "exportable" when a new
2878 variable is defined.
2879 (target_environment): Use the "exportable" flag instead of
2880 re-checking the name here... an efficiency improvement.
2882 2002-07-31 Paul D. Smith <psmith@gnu.org>
2884 * config.h-vms.template: Updates to build on VMS. Thanks to
2885 Brian_Benning@aksteel.com for helping verify the build.
2886 * makefile.com: Build the new hash.c file.
2887 * hash.h: Use strcpmi(), not stricmp(), in the
2888 HAVE_CASE_INSENSITIVE_FS case.
2890 2002-07-30 Paul D. Smith <psmith@gnu.org>
2892 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2893 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2894 Reported by <Brian_Benning@aksteel.com>.
2896 2002-07-10 Paul D. Smith <psmith@gnu.org>
2898 * variable.c (pop_variable_scope): Remove variable made unused by
2899 new hash infrastructure.
2900 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2901 comparisons as well as name comparisons.
2902 * variable.h: Add a prototype for new hash_init_function_table().
2903 * file.c (lookup_file): Remove variables made unused by new hash
2905 * dir.c (directory_contents_hash_2): Missing return of hash value.
2906 (dir_contents_file_exists_p): Remove variables made unused by new
2907 hash infrastructure.
2910 Installed Greg McGary's integration of the hash functions from the
2911 GNU id-utils package:
2913 2002-07-10 Greg McGary <greg@mcgary.org>
2915 * scripts/functions/filter-out: Add literals to to the
2916 pattern space in order to add complexity, and trigger
2917 use of an internal hash table. Fix documentation strings.
2918 * scripts/targets/INTERMEDIATE: Reverse order of files
2919 passed to expected `rm' command.
2921 2002-07-10 Greg McGary <greg@mcgary.org>

2998 variable_hash_cmp): New functions.

3013 2002-07-10 Paul D. Smith <psmith@gnu.org>
3015 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3016 prerequisite list. A real SysV make will expand the entire
3017 prerequisites list _twice_: we don't do that as it's a big
3018 backward-compatibility problem. We only replace those specific
3021 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3022 references left in the list of prerequisites. Check for .POSIX as
3023 we record targets, so we can disable non-POSIX behavior while
3024 reading makefiles as well as running them.
3025 (eval): Check the prerequisite list to see if we have anything
3026 that looks like a SysV prerequisite variable reference.
3028 2002-07-09 Paul D. Smith <psmith@gnu.org>
3030 * doc/make.texi (Prerequisite Types): Add a new section describing
3031 order-only prerequisites.
3033 * read.c (uniquize_deps): If we have the same file as both a
3034 normal and order-only prereq, get rid of the order-only prereq,
3035 since the normal one supersedes it.
3037 2002-07-08 Paul D. Smith <psmith@gnu.org>
3039 * AUTHORS: Added Greg McGary to the AUTHORS file.
3040 * NEWS: Blurbed order-only prerequisites.
3041 * file.c (print_file): Show order-only deps properly when printing
3044 * maintMakefile: Add "update" targets for wget'ing the latest
3045 versions of various external files. Taken from Makefile.maint in
3048 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3049 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3051 2002-07-07 Paul D. Smith <psmith@gnu.org>
3053 * po/*.po: Remove. We'll use wget to retrieve them at release
3056 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3057 rather than a shell you get an exception. Make sure we look up
3058 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3060 * remake.c (notice_finished_file): Fix handling of -t flag.
3061 Patch provided by Henning Makholm <henning@makholm.net>.
3063 * implicit.c (pattern_search): Some systems apparently run short
3064 of stack space, and using alloca() in this function caused an
3065 overrun. I modified it to use xmalloc() on the two variables
3066 which seemed like they might get large. Fixes Bug #476.
3068 * main.c (print_version): Update copyright notice to conform with
3070 (print_usage): Update help output.
3072 * function.c (func_eval): Create a new make function, $(eval
3073 ...). Expand the arguments, put them into a buffer, then invoke
3074 eval_buffer() on the resulting string.
3075 (func_quote): Create a new function, $(quote VARNAME). Inserts
3076 the value of the variable VARNAME without expanding it any
3079 * read.c (struct ebuffer): Change the linebuffer structure to an
3080 "eval buffer", which can be either a file or a buffer.
3081 (eval_makefile): Move the code in the old read_makefile() which
3082 located a makefile into here: create a struct ebuffer with that
3083 information. Have it invoke the new function eval() with that
3085 (eval_buffer): Create a new function that creates a struct ebuffer
3086 that holds a string buffer instead of a file. Have it invoke
3087 eval() with that ebuffer.
3088 (eval): New function that contains the guts of the old
3089 read_makefile() function: this function parses makefiles. Obtains
3090 data to parse from the provided ebuffer. Some modifications to
3091 make the flow of the function cleaner and clearer. Still could
3092 use some work here...
3093 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3094 contents of the define/endef variable from the ebuffer.
3095 (readstring): Read the next line from a string-style ebuffer.
3096 (readline): Read the next line from an ebuffer. If it's a string
3097 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3100 * dep.h (eval_buffer): Prototype eval_buffer();
3102 * variable.c (do_variable_definition): Make sure that all
3103 non-target-specific variables are registered in the global set.
3104 If we're invoked from an $(eval ...) we might be inside a $(call
3105 ...) or other function which has pushed a variable scope; we still
3106 want to define our variables from evaluated makefile code in the
3109 2002-07-03 Greg McGary <greg@mcgary.org>
3111 * dep.h (struct dep) [ignore_mtime]: New member.
3112 [changed]: convert to a bitfield.
3113 * implicit.c (pattern_search): Zero ignore_mtime.
3114 * main.c (main, handle_non_switch_argument): Likewise.
3115 * rule.c (convert_suffix_rule): Likewise.
3116 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3117 (read_makefile): Parse '|' in prerequisite list.
3118 (uniquize_deps): Consider ignore_mtime when comparing deps.
3119 * remake.c (update_file_1, check_dep): Don't force remake for
3120 dependencies that have d->ignore_mtime.
3121 * commands.c (FILE_LIST_SEPARATOR): New constant.
3122 (set_file_variables): Don't include a
3123 prerequisite in $+, $^ or $? if d->ignore_mtime.
3126 2002-06-18 Paul D. Smith <psmith@gnu.org>
3128 * make.texinfo: Updates for next revision. New date/rev/etc.
3129 Recreate all Info menus. Change license on the manual to the GNU
3130 Free Documentation License. A number of typos.
3131 (Variables Simplify): Don't use "-" before it's defined.
3132 (Automatic Prerequisites): Rewrite the target example to work
3133 properly if the compile fails. Remove incorrect comments about
3134 how "set -e" behaves.
3135 (Text Functions): Move the "word", "wordlist", "words", and
3136 "firstword" functions here, from "File Name Functions".
3137 * make-stds.texi: Update from latest GNU version.
3138 * fdl.texi: (created) Import the latest GNU version.
3140 2002-06-06 Paul D. Smith <psmith@gnu.org>
3142 * variable.c (do_variable_definition): New function: extract the
3143 part of try_variable_definition() that actually sets the value
3144 into a separate function.
3145 (try_variable_definition): Call do_variable_definition() after
3146 parsing the variable definition string.
3147 (define_variable_in_set): Make the name argument const.
3149 * variable.h (enum variable_flavor): Make public.
3150 (do_variable_definition): Create prototype.
3152 * read.c (read_all_makefiles): Create a new built-in variable,
3154 (read_makefile): Add each makefile read in to this variable value.
3156 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3158 * Makefile.DOS.template: Tweak according to changes in the
3159 distribution. Add back the dependencies of *.o files.
3161 * configh.dos.template: Synchronize with config.h.in.
3163 2002-05-09 Paul D. Smith <psmith@gnu.org>
3165 * file.c (file_timestamp_now): Use K&R function declaration.
3167 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3168 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3169 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3170 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3171 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3172 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3173 nlist.n_name is a pointer rather than an array.
3175 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3176 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3177 * configure.in: Use it instead of the old version.
3179 * main.c (main): Prefer setvbuf() to setlinebuf().
3181 2002-05-08 Paul D. Smith <psmith@gnu.org>
3183 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3184 (loadavg_LDADD): Ditto.
3186 2002-04-29 Paul D. Smith <psmith@gnu.org>
3188 * expand.c (recursively_expand_for_file): Rename
3189 recursively_expand() to recursively_expand_for_file() and provide
3190 an extra argument, struct file. If the argument is provided, set
3191 the variable scope to that of the file before expanding.
3192 * variable.h (recursively_expand): Make this a macro that invokes
3193 recursively_expand_for_file() with a NULL file pointer.
3194 * variable.c (target_environment): Call the renamed function and
3195 provide the current file context.
3196 Fixes Debian bug #144306.
3198 2002-04-28 Paul D. Smith <psmith@gnu.org>
3200 Allow $(call ...) user-defined variables to be self-referencing
3201 without throwing an error. Allows implementation of transitive
3202 closures, among other possibly useful things.
3203 Requested by: Philip Guenther <guenther@sendmail.com>
3205 * variable.h (struct variable): Add a new field: exp_count, and
3206 new macros to hold its size and maximum value.
3207 (warn_undefined): Make this a macro.
3208 * variable.c (define_variable_in_set): Initialize it.
3209 * expand.c (recursively_expand): If we detect recursive expansion
3210 of a variable, check the exp_count field. If it's greater than 0
3211 allow the recursion and decrement the count.
3212 (warn_undefined): Remove this (now a macro in variable.h).
3213 * function.c (func_call): Before we expand the user-defined
3214 function, modify its exp_count field to contain the maximum
3215 number of recursive calls we'll allow. After the call, reset it
3218 2002-04-21 Paul D. Smith <psmith@gnu.org>
3220 Modified to use latest autoconf (2.53), automake (1.6.1), and
3221 gettext (0.11.1). We're using gettext's new "external" support,
3222 to avoid including libintl source with GNU make.
3224 * README.cvs: New file. Explain how to build GNU make from CVS.
3226 * configure.in: Modify checking for the system glob library.
3227 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3228 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3229 etc. will manage it correctly). Set an automake conditional
3230 USE_LOCAL_GLOB to decide whether to compile the glob library.
3232 * getloadavg.c (main): Include make.h in the "TEST" program to
3235 * Makefile.am: Remove special rules for loadavg. Replace them
3236 with Automake capabilities for building extra programs.
3238 * signame.c: This file does nothing if the system provide
3239 strsignal(). If not, it implements strsignal(). If the system
3240 doesn't define sys_siglist, then we make our own; otherwise we use
3242 * signame.h: Removed.
3244 * main.c (main): No need to invoke signame_init(). Update copyright.
3246 * ABOUT-NLS: Removed.
3247 * gettext.c: Removed.
3248 * gettext.h: Get a simplified copy from the gettext package.
3250 * i18n/*.po: Moved to po/.
3253 * config/*: Created. Contains package configuration helper files.
3254 * config.guess, config.sub: Moved to config directory.
3256 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3257 Rework to use new-style autoconf features. Use the "external"
3258 mode for gettext. Make the build.sh config file conditional on
3259 whether build.sh.in exists, to avoid autoconf errors.
3260 * acinclude.m4: Removed almost all macros as being obsolete.
3261 Rewrote remaining macros to use AC_DEFINE.
3262 * acconfig.h: Removed.
3264 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3265 conditional to handle customs support. Remove special handling
3268 2002-04-20 Paul D. Smith <psmith@gnu.org>
3270 * function.c (func_call): Don't mark the argument variables $1,
3271 etc. as recursive. They've already been fully expanded so
3272 there's no need to do it again, and doing so strips escaped $'s.
3273 Reported by Sebastian Glita <glseba@yahoo.com>.
3275 * remake.c (notice_finished_file): Walk through double-colon
3276 entries via the prev field, not the next field!
3277 Reported by Greg McGary <greg@mcgary.org>.
3279 * main.c (main): If the user specifies -q and asks for a specific
3280 target which is a makefile, we got an assert. In that case it
3281 turns out we should continue normally instead.
3283 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3285 * i18n/he.po: Installed a new translation.
3287 2002-01-07 Paul D. Smith <psmith@gnu.org>
3289 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3291 2001-12-04 Paul D. Smith <psmith@gnu.org>
3293 * i18n/ja.po: Installed an updated translation.
3295 2001-09-06 Paul Eggert <eggert@twinsun.com>
3297 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3298 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3300 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3302 (main): Get rid of any avoidable limit on stack size.
3304 2001-09-04 Paul D. Smith <psmith@gnu.org>
3306 * i18n/da.po: Installed an updated translation.
3308 2001-08-03 Paul D. Smith <psmith@gnu.org>
3310 * i18n/fr.po: Installed an updated translation.
3311 Resolves Debian bug #106720.
3313 2001-06-13 Paul D. Smith <psmith@gnu.org>
3315 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3318 2001-06-11 Paul D. Smith <psmith@gnu.org>
3320 * i18n/ko.po: Installed a new translation.
3322 2001-05-06 Paul D. Smith <psmith@gnu.org>
3324 Modify the EINTR handling.
3326 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3327 the way in which we manage the file descriptor/signal handler race
3328 trap to be more efficient.
3330 2001-05-06 Paul Eggert <eggert@twinsun.com>
3332 Restart almost all system calls that are interrupted, instead
3333 of worrying about EINTR. The lone exception is the read() for
3336 * configure.in (HAVE_SA_RESTART): New macro.
3337 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3338 * main.c (main): Use SA_RESTART instead of the old,
3339 nonstandard SA_INTERRUPT.
3341 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3342 * main.c (bsd_signal): New function or macro,
3343 if the implementation doesn't supply it.
3344 (The bsd_signal function will be in POSIX 1003.1-200x.)
3345 (HANDLESIG): Remove.
3346 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3348 * make.h (EINTR_SET): Remove.
3349 (SA_RESTART): New macro.
3351 * arscan.c (ar_member_touch): Don't worry about EINTR.
3352 * function.c (func_shell): Likewise.
3353 * job.c (reap_children, free_child, new_job): Likewise.
3354 * main.c (main): Likewise.
3355 * remake.c (touch_file, name_mtime): Likewise.
3357 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3358 if fstat failed with errno!=EINTR, the error was ignored.
3360 * job.c (set_child_handler_action_flags): New function.
3361 (new_job): Use it to temporarily clear the SIGCHLD action flags
3362 while reading the token.
3364 2001-05-02 Paul D. Smith <psmith@gnu.org>
3366 * job.c (start_job_command): Don't add define/endef per-line flags
3367 to the top-level flags setting.
3369 2001-04-03 Paul D. Smith <psmith@gnu.org>
3371 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3372 bit on error, so check for odd return values, not non-0 return
3374 (VMS_get_member_info): Calculate the timezone differences correctly.
3375 Reported by John Fowler <jfowler@nyx.net>.
3378 2001-03-14 Paul D. Smith <psmith@gnu.org>
3380 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3381 value before invoking define_variable().
3382 Reported by John Fowler <jfowler@nyx.net>.
3384 2001-02-07 Paul D. Smith <psmith@gnu.org>
3386 * read.c (record_target_var): If we reset the variable due to a
3387 command-line variable setting overriding it, turn off the "append"
3390 2001-01-17 Paul D. Smith <psmith@gnu.org>
3392 * variable.c (lookup_variable) [VMS]: When getting values from the
3393 environment, allocate enough space for the _value_ plus escapes,
3394 not enough space for the name plus escapes :-/.
3395 Reported by John Fowler <jfowler@nyx.net>.
3397 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3398 warnings that make generates, so it doesn't look like an error.
3399 Reported by Karl Berry <karl@gnu.org>.
3402 Fix for PR/2020: Rework appended target-specific variables. I'm
3403 fairly confident this algorithm is finally correct.
3405 * expand.c (allocated_variable_append): Rewrite. Instead of
3406 expanding each appended variable then adding all the expanded
3407 strings together, we append all the unexpanded values going up
3408 through the variable set contexts, then expand the final result.
3409 This behaves just like non-target-specific appended variable
3410 values, while the old way didn't in various corner cases.
3411 (variable_append): New function: recursively append the unexpanded
3412 value of a variable, walking from the outermost variable scope to
3414 * variable.c (lookup_variable): Remove the code that looked up the
3415 variable set list if the found variable was "append". We don't
3417 (lookup_variable_in_set): Make this non-static so we can use it
3419 (try_variable_definition): Use lookup_variable_in_set() rather
3420 than faking out current_variable_set_list by hand (cleanup).
3421 * variable.h: Add a prototype for the now non-static
3422 lookup_variable_in_set().
3424 2000-11-17 Paul D. Smith <psmith@gnu.org>
3426 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3427 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3428 before throwing a fit.
3430 2000-11-17 Paul D. Smith <psmith@gnu.org>
3432 * read.c (readline): CRLF calculations had a hole, if you hit the
3433 buffer grow scenario just right. Reworked the algorithm to avoid
3434 the need for len or lastlen at all. Problem description with
3435 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3437 2000-10-24 Paul D. Smith <psmith@gnu.org>
3439 * gettext.c (SWAP): Declare this with the prototype, otherwise
3440 some systems don't work (non-32-bit? Reported for Cray T3E).
3441 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3443 2000-10-05 Paul D. Smith <psmith@gnu.org>
3445 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3446 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3448 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3450 2000-09-22 Paul D. Smith <psmith@gnu.org>
3452 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3453 parts of the real gettext.h here, and we expect to really include
3454 the real gettext.h later. If we keep this #define, it's ignored.
3456 2000-09-21 Paul D. Smith <psmith@gnu.org>
3458 * main.c (log_working_directory): Rework the text to use complete
3459 sentences, to make life simpler for the translators.
3461 2000-08-29 Paul D. Smith <psmith@gnu.org>
3463 * file.c (remove_intermediates): Print a debug message before we
3464 remove intermediate files, so the user (if she uses -d) knows
3467 2000-08-21 Paul D. Smith <psmith@gnu.org>
3469 * variable.c (try_variable_definition): Change how we handle
3470 target-specific append variable defns: instead of just setting the
3471 value, expand it as an append _but_ only within the current
3472 target's context. Otherwise we lose all but the last value if the
3473 variable is appended more than once within the current target
3474 context. Fixes PR/1831.
3476 2000-08-16 Paul D. Smith <psmith@gnu.org>
3478 * function.c (func_shell): Nul-terminate the buffer before
3479 printing an exec error message (just in case it's not!).
3480 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3482 2000-07-25 Paul D. Smith <psmith@gnu.org>
3484 * job.c (construct_command_argv_internal): Add "~" to the list of
3485 sh_chars[] which disallow optimizing out the shell call.
3487 2000-07-23 Paul Eggert <eggert@twinsun.com>
3489 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3490 supersedes --disable-nsec-timestamps.
3491 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3492 * README: Remove --disable-nsec-timestamps.
3494 * filedef.h (struct file.low_resolution_time): New member.
3495 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3496 * remake.c (update_file_1):
3497 Avoid spurious rebuilds due to low resolution time stamps,
3498 generalizing the earlier code that applied only to archive members.
3499 (f_mtime): Archive members always have low resolution time stamps.
3501 * configure.in: Remove --disable-nsec-timestamps, as this has
3502 been superseded by .LOW_RESOLUTION_TIME.
3504 2000-07-23 Paul Eggert <eggert@twinsun.com>
3506 * configure.in (enable_nsec_timestamps): Renamed from
3507 make_cv_nsec_timestamps, since enable/disable options
3508 shouldn't be cached.
3510 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3511 and Paul Eggert <eggert@twinsun.com>
3513 * file.c (file_timestamp_now):
3514 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3515 so that clock_gettime is not linked unless needed.
3517 * filedef.h (FILE_TIMESTAMP_HI_RES):
3518 Remove definition; "configure" now does this.
3520 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3521 to before high resolution file timestamp check,
3522 since that check now uses uintmax_t.
3523 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3524 high resolution file timestamps.
3525 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3526 so that we don't link in clock_gettime unnecessarily.
3528 2000-07-17 Paul D. Smith <psmith@gnu.org>
3530 * i18n/ja.po: New version of the translation file.
3532 2000-07-07 Paul D. Smith <psmith@gnu.org>
3534 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3535 the offset calculation.
3536 (name_mtime): Replace EINTR test with EINTR_SET macro.
3538 2000-07-07 Paul Eggert <eggert@twinsun.com>
3542 * remake.c (update_file_1):
3543 Avoid spurious rebuilds of archive members due to their
3544 timestamp resolution being only one second.
3545 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3546 the clock's resolution being lower than file timestamps'.
3547 When warning about future timestamps, report only the discrepancy,
3548 not the absolute value of the timestamp and the current time.
3550 * file.c (file_timestamp_now): New arg RESOLUTION.
3551 * filedef.h (file_timestamp_now): Likewise.
3552 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3554 2000-07-05 Paul D. Smith <psmith@gnu.org>
3556 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3557 to listp. Fixes PR/1793.
3559 2000-06-26 Paul Eggert <eggert@twinsun.com>
3561 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3563 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3565 * remake.c (f_mtime): Remove unused var memtime.
3567 2000-06-25 Martin Buchholz <martin@xemacs.org>
3569 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3570 Ran spell-check on make.texinfo.
3572 2000-06-23 Paul D. Smith <psmith@gnu.org>
3574 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3575 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3576 * make.h: Define these macros.
3578 * Version 3.79.1 released.
3580 * configure.in: Add a new option, --disable-nsec-timestamps, to
3581 avoid using sub-second timestamps on systems that support it. It
3582 can lead to problems, e.g. if your makefile relies on "cp -p".
3583 * README.template: Document the issue with "cp -p".
3585 * config.guess, config.sub: Updated.
