1 2009-08-31 Eli Zaretskii <eliz@gnu.org>
3 * function.c (windows32_openpipe): Update envp after calling
6 2009-08-01 Paul Smith <psmith@gnu.org>
8 * expand.c (expand_argument): If the argument is large enough use
9 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
11 * variable.c (do_variable_definition): Avoid using alloca() to
12 hold values, which can be large. Fixes Savannah bug #23960.
14 * job.c (new_job): Use memmove() instead of strcpy() since both
15 pointers are in the same memory block. Fixes Savannah bug #27148.
16 Patch by Petr Machata.
18 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
20 * job.c (construct_command_argv_internal): Add "ulimit" and
21 "unset" to the sh_cmds for Unixy shells.
23 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
25 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
26 that set make_cv_sys_gnu_glob, so they are also correctly set
27 when the cache has been populated before.
29 2009-07-04 Eli Zaretskii <eliz@gnu.org>
31 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
32 exist, as realpath(3) does where it's supported.
34 2006-07-04 Eli Zaretskii <eliz@gnu.org>
36 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
37 (abspath): Support systems that define HAVE_DOS_PATHS (have
38 drive letters in their file names). Use IS_PATHSEP instead of a
39 literal '/' comparison. Fixes Savannah bug #26886.
41 2009-06-14 Paul Smith <psmith@gnu.org>
43 * remake.c (update_file_1): Remember the original file we marked
44 as updating, so we can clear that flag again. If we find a target
45 via vpath, FILE might change.
46 (check_dep): Ditto. Fixes Savannah bug #13529.
47 Patch by Reid Madsen <reid.madsen@tek.com>.
49 2009-06-13 Paul Smith <psmith@gnu.org>
51 * doc/make.texi (MAKEFILES Variable): Be explicit that files
52 included by MAKEFILES cannot give default goals.
53 * read.c (eval): If set_default is not set, pass the no-default-goal
54 value when we read included makefiles. Fixes Savannah bug #13401.
56 * ar.c (ar_name): Ensure that targets with empty parens aren't
57 considered archive member references: archive members must have a
58 non-empty "member" string. Fixes Savannah bug #18435.
60 * function.c (string_glob): Rely on multi_glob() to determine
61 whether files exist or not. Remove call to file_exists_p() which
62 is not always correct. Fixes Savannah bug #21231.
63 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
64 then only files that really exist will be returned.
65 * dep.h: Add new argument to multi_glob().
66 * rule.c (install_pattern_rule): Ditto.
67 * read.c (eval): Ditto.
68 * main.c (main): Ditto.
69 * implicit.c (pattern_search): Ditto.
70 * file.c (parse_prereqs): Ditto.
71 * default.c (set_default_suffixes): Ditto.
73 2009-06-09 Paul Smith <psmith@gnu.org>
75 * commands.c (set_file_variables): If always_make_flag is set,
76 always add the prereq to $?. Fixes Savannah bug #17825.
78 * remake.c (update_file_1): When rebuilding deps of FILE, also try
79 to rebuild the deps of all the also_make targets for that file.
80 Fixes Savannah bug #19108.
82 * implicit.c (pattern_search): Undo test for is_target, added by
83 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
84 Rule Search Algorithm". Fixes Savannah bug #17752.
86 * main.c (clean_jobserver): Clear the jobserver_fds options and
87 set job_slots to the default when we clean up.
88 (define_makeflags): Return the new MAKEFLAGS value.
89 (main): Reset MAKEFLAGS in the environment when we re-exec.
90 Fixes Savannah bug #18124.
92 2009-06-08 Paul Smith <psmith@gnu.org>
94 * read.c (eval): Collapse continuations post-semicolon on target-
95 specific variables. Fixes Savannah bug #17521.
97 2009-06-07 Paul Smith <psmith@gnu.org>
99 * job.c (reap_children): For older systems without waitpid() (are
100 there any of these left?) run wait(2) inside EINTRLOOP to handle
101 EINTR errors. Fixes Savannah bug #16401.
103 * (various): Debug message cleanup. Fixes Savannah bug #16469.
105 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
107 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
108 not the end, to catch second expansion $(eval ...) defining new
109 target/prereq relationships during snap_deps.
110 Fixes Savannah bug #24622.
112 * read.c (record_files): The second-expansion "f->updating" hack
113 was not completely correct: if assumed that the target with
114 commands always had prerequisites; if one didn't then the ordering
115 was messed up. Fixed for now to use f->updating to decide whether
116 to preserve the last element in the deps list... but this whole
117 area of constructing and reversing the deps list is too confusing
118 and needs to be reworked. Fixes Savannah bug #21198.
120 2009-06-06 Paul Smith <psmith@gnu.org>
122 * hash.c (hash_insert): Remove useless test for NULL.
123 Fixes Savannah bug #21823.
125 * make.h: Move SET_STACK_SIZE determination to make.h.
126 * main.c (main): New global variable, STACK_LIMIT, holds the
127 original stack limit when make was started.
128 * job.c (start_job_command): Reset the stack limit, if we changed it.
129 Fixes Savannah bug #22010.
131 * remake.c (check_dep): Only set the target's state to not-started
132 if it's not already running. Found this while testing -j10 builds
133 of glibc: various targets were being rebuilt multiple times.
134 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
137 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
138 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
141 2009-06-04 Paul Smith <psmith@gnu.org>
143 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
145 * maintMakefile: Modify access of config and gnulib Savannah
146 modules to use GIT instead of CVS.
148 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
149 Fixes Savannah bug #24655.
151 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
152 this can happen during some invocations of $(eval ...) for example.
153 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
155 2009-06-02 Paul Smith <psmith@gnu.org>
157 * configure.in: Check for fileno()
158 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
159 for the makefile file so invocations of $(shell ...) don't inherit it.
160 Fixes Savannah bug #24277.
162 2009-06-01 Paul Smith <psmith@gnu.org>
164 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
165 expansion was handled incorrectly. Rework the default goal
166 handling to save the variable only. Remove default_goal_file and
168 * read.c (eval): Check default_goal_var, not default_goal_name.
169 * read.c (record_target_var): Don't check default_goal_file here.
171 2009-05-31 Paul Smith <psmith@gnu.org>
173 * main.c (main): Expand the .DEFAULT_GOAL variable before using
174 it, and if the multi_glob() returns nothing (say it expanded to
175 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
177 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
178 $(and ..) to the reference. Fixes Savannah bug #25694.
180 * make.1: Be clear that some recipes will be executed even with -n.
181 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
183 * doc/make.texi (Override Directive): Make more clear how
184 overrides and appends interact.
185 Elucidates part of Savannah bug #26207.
187 * read.c (record_target_var): Don't reset the origin on
188 target-specific variables; try_variable_definition() will handle
189 this correctly. Fixes Savannah bug #26207.
191 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
192 Fixes Savannah bug #25712.
194 * implicit.c (pattern_search): Keep a pointer to the beginning of
195 the filename and save that instead of the constructed pointer.
196 Fixes Savannah bug #26593.
197 Patch by Mark Seaborn <mrs@mythic-beasts.com>
199 2009-05-30 Paul Smith <psmith@gnu.org>
201 * doc/make.texi (Multi-Line): Add a description of the new abilities
202 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
203 "command sequence" vs. "recipe" syntax.
204 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
205 after a define, to create variables with those flavors.
207 2009-05-25 Paul Smith <psmith@gnu.org>
209 Reworked the parser for variable assignments to allow multiple
210 modifiers, and in any order. Also allows variable and
211 prerequisites to be modifier names ('export', 'private', etc.)
213 * NEWS: Add notes about user-visible changes.
215 * read.c (struct vmodifiers): Remember what modifiers were seen.
216 (parse_var_assignment): New function to parse variable assignments.
217 (eval): Call the new function. Handle variable assignments earlier.
219 * variable.c (parse_variable_definition): Only parse; don't create var.
220 (assign_variable_definition): Call parse, then create the var.
222 2009-05-24 Paul Smith <psmith@gnu.org>
224 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
225 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
227 2009-03-14 Eli Zaretskii <eliz@gnu.org>
229 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
230 Fixes Savannah bug #25412.
232 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
233 prototype for xmalloc.
234 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
235 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
236 Loop over an array of extensions, instead of duplicating the same
237 code inline. Use SearchPath followed by CreateFile, instead of
238 the obsolete OpenFile. Fixes Savannah bug #17277.
239 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
240 to `find_file'. Fixes Savannah bug #25662.
242 2009-03-07 Eli Zaretskii <eliz@gnu.org>
244 * function.c (func_shell): Don't close pipedes[1] if it is -1.
245 Fixes Savannah bug #20495.
247 2009-02-28 Ralf Wildenhues <address@hidden>
249 * doc/make.texi (Instead of Execution): Document interaction of
250 -t with phony targets.
252 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
254 Introduce a new keyword "private" which applies to target-specific
255 variables and prevents their values from being inherited.
257 * variable.h (struct variable): Add private_var flag to each variable.
258 Add a flag to specify which list entry switches to the parent target.
259 * variable.c (define_variable_in_set): Initialize private_var flag.

261 (initialize_file_variables): Set next_is_parent appropriately.
262 (print_variable): Show the private_var flag.
263 * read.c (eval): Recognize the private keyword.
264 (record_target_var): Set private_var.
265 * doc/make.texi (Suppressing Inheritance): Add documentation.
267 2008-10-26 Paul Smith <psmith@gnu.org>
269 * configure.in: Check for strndup().
270 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
272 * make.h: Rename savestring to xstrndup.
273 * commands.c (chop_commands): Ditto.
274 * function.c (func_foreach): Ditto.
275 * read.c (eval, record_files): Ditto.
276 * variable.c (define_variable_in_set): Ditto.
278 2008-09-30 Eli Zaretskii <eliz@gnu.org>
280 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
283 * w32/subproc/build.bat (GCCBuild): Likewise.
285 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
287 * job.c (construct_command_argv_internal): Avoid extra backslash
288 in batch-mode Unixy shells. Under DB_JOBS, display the contents
291 2008-05-31 Eli Zaretskii <eliz@gnu.org>
293 * README.W32.template: Remove obsolete text about non-support for
294 -jN without Unixy shell. Remove obsolete text about not supplying
295 Visual Studio project files (we do supply them). Modify text to
296 prefer GCC builds to MSC builds.
298 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
300 * doc/make.texi (Empty Targets): Fix typo.
302 2008-03-27 Paul Smith <psmith@gnu.org>
304 Fix Savannah bug #22379:
305 * ar.c (ar_glob_match): Zero the allocated structure.
306 * read.c (parse_file_seq): Ditto.
308 2008-03-08 Brian Dessent <brian@dessent.net>
310 * maintMakefile: Update Translation Project location.
312 2008-01-26 Eli Zaretskii <eliz@gnu.org>
314 * variable.c (target_environment): Don't use shell_var if its
315 `value' field is NULL.
317 2007-12-22 Eli Zaretskii <eliz@gnu.org>
319 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
321 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
322 (TEXINFOS): Value changed to `doc/make.texi'.
323 (.SUFFIXES): Use .texi instead of .texinfo.
324 (make.info, make.dvi): Depend on doc/make.texi.
325 (.texi.info): New target, instead of ".texinfo.info". Change -I
326 switch to $(MAKEINFO) to look in doc/. Use --no-split.
327 (.texi): New target, instead of ".texinfo". Change -I switch to
328 $(MAKEINFO) to look in doc/. Use --no-split.
329 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
330 switch to $(MAKEINFO) to look in doc/.
331 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
332 "*.i[0-9][0-9]" (due to --no-split above).
333 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
334 (html, make_1.html): New targets.
335 (.PHONY): Add "html".
336 (.SUFFIXES): Add .html.
338 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
340 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
341 HAVE_DECL_SYS_SIGLIST.
343 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
344 build does not use child_execute_job.
346 * variable.c (define_automatic_variables) [__MSDOS__]: Always
347 export the SHELL environment variable to the child.
349 2007-12-22 Eli Zaretskii <eliz@gnu.org>
351 * config.h.W32: Include sys/types.h.
352 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

355 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
358 2007-11-04 Paul Smith <psmith@gnu.org>
360 * doc/make.texi: Convert references to "commands", "command
361 lines", and "command script" to "recipe".
363 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
366 2007-10-27 Bruno Haible <bruno@clisp.org>
368 * remake.c (f_mtime): Print time difference values between 100 and
369 ULONG_MAX in fixed-point notation rather than in exponention notation.
371 2007-10-12 Eli Zaretskii <eliz@gnu.org>
373 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
374 a more complex value than a simple shell: if it's not a default
375 shell now then expand it and see if is a default shell then.
377 2007-10-10 Eli Zaretskii <eliz@gnu.org>
379 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
380 pathnames, with const strings.
381 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
382 from the template (used for building from CVS, not a dist).
384 2007-10-10 Paul Smith <psmith@gnu.org>
386 * make.h: Add a prototype for w32_kill() (change suggested by
387 Yongwei Wu <wuyongwei@gmail.com>).
389 2007-09-21 Eli Zaretskii <eliz@gnu.org>
391 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
394 2007-09-12 Paul Smith <psmith@gnu.org>
396 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
397 Provided by Diego Biurrun <diego@biurrun.de>
398 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
399 Provided by Diego Biurrun <diego@biurrun.de>
401 2007-09-11 Paul Smith <psmith@gnu.org>
403 * doc/make.texi (Special Variables): Moved this into the "How to
404 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
405 (MAKEFILE_LIST) No longer a section; this was added into the
406 "Special Variables" section.
407 (Rule Introduction): Reference .RECIPEPREFIX.
408 (Simple Makefile): Ditto.
409 (Rule Syntax): Ditto.
410 (Command Syntax): Ditto.
411 (Error Messages): Ditto.
413 2007-09-10 Paul Smith <psmith@gnu.org>
415 * commands.c (print_commands): Don't print an extra line in the
416 command scripts. Prefix the command scripts with cmd_prefix, not \t.
418 * read.c (construct_include_path): Add the full string to the cache; we
419 were chopping the last char.
421 * NEWS: Announce the .RECIPEPREFIX special variable.
422 * variable.c (lookup_special_var): Rename from handle_special_var().
423 (lookup_variable): Call the new name.
424 (set_special_var): New function: handle setting of special variables.
425 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
426 (do_variable_definition): Call it.
427 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
428 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
429 * main.c (main): Create the .RECIPEPREFIX special variable.
430 * read.c (eval): Remove the cmd_prefix characters from the command
431 scripts here, so they're not stored in the commands array at all,
432 rather than waiting and stripping them out during command construction.
433 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
435 2007-08-15 Paul Smith <psmith@gnu.org>
437 * doc/make.texi (GNU Free Documentation License): The fdl.texi
438 file has had the section info removed, so add some to make.texi
439 before we include it.
441 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
443 * remake.c (check_dep): Reset the target state for intermediate
444 files. They might have been considered before but not updated
445 then (order-only for example) but they will be this time.
446 Fixes Savannah bug #'s 3330 and 15919.
448 2007-07-21 Eli Zaretskii <eliz@gnu.org>
450 Fix Savannah bug #20549:
451 * function.c (func_shell): Call construct_command_argv with zero
453 * job.c (construct_command_argv_internal): New argument FLAGS; all
455 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
457 * job.h (construct_command_argv_internal): Update prototype.
459 2007-07-13 Paul Smith <psmith@gnu.org>
461 * file.c (expand_deps): Use variable_buffer as the start of the
462 buffer, not the original pointer (in case it was reallocated).
463 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
464 Fixes Savannah bug #20452.
466 2007-07-04 Paul Smith <psmith@gnu.org>
468 * (ALL FILES): Update to GPLv3.
469 * (ALL FILES): Update copyright for 2007.
471 * main.c (print_version): Move the host type info to the second line.
473 2007-06-29 Thiemo Seufer <ths@mips.com>
475 * maintMakefile: Update Translation Project location.
477 2007-06-13 Paul Smith <psmith@gnu.org>
479 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
480 "Expansion of a deferred"
481 Fixes Savannah bug #20018.
483 * expand.c (variable_expand_for_file): Preserve the value of
484 reading_file rather than setting it to 0 at the end.
485 Fixes Savannah bug #20033.
487 2007-05-11 Paul Smith <psmith@gnu.org>
489 * job.c (new_job): Add debug info to specify where make found the
490 command script it is running to build a target.
491 Fixes Savannah bug #18617.
493 * default.c (default_suffixes,default_suffix_rules,default_variables):
494 Add support for Objective C. Fixes Savannah bug #16389.
495 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
497 * function.c (func_lastword): Initialize p.
499 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
500 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
501 Dave Korn <dave.korn@artimi.com>
503 2007-05-08 Paul Smith <psmith@gnu.org>
505 Fix Savannah bug #19656:
507 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
509 * make.h: Change all case-insensitive string compares to use
510 strcasecmp() (from POSIX). If we don't have that but do have one
511 of the others, define strcasecmp to be one of those instead. If
512 we don't have any, declare a prototype for our own version.
514 * misc.c (strcasecmp): Use this if we can't find any native
515 case-insensitive string comparison function.
516 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
517 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
519 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
520 strcasecmp() instead of stricmp().
521 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
522 instead of strcmpi().
523 * acinclude.m4: Remove the strcasecmp() check from here.
525 2007-03-21 Paul Smith <psmith@gnu.org>
527 * configure.in: Don't turn on case-insensitive file system support
528 if --disable-... is given. Fixes Savannah bug #19348.
530 2007-03-19 Paul Smith <psmith@gnu.org>
532 * ALL: Use the strcache for all file name strings, or other
533 strings which we will never free. The goal is to save memory by
534 avoiding duplicate copies of strings. However, at the moment this
535 doesn't save much memory in most situations: due to secondary
536 expansion we actually save prerequisite lists twice (once before
537 the secondary expansion, and then again after it's been parsed
538 into individual file names in the dep list). We will resolve this
539 in a future change, by doing the parsing up-front for targets
540 where secondary expansion is not set.
542 Moving things into the strcache also allows us to use const
543 pointers in many more places.
545 2007-01-03 Paul Smith <psmith@gnu.org>
547 * make.h (ENULLLOOP): Reset errno after each failed invocation of
548 the function, not just the first. Fixes Savannah bug #18680.
550 2006-11-18 Paul Smith <psmith@gnu.org>
552 * strcache.c (strcache_add_len): Don't allocate a new buffer
553 unless the string is not already nil-terminated. Technically this
554 is a violation of the standard, since we may be passed an array
555 that is not long enough to test one past. However, in make this
556 is never true since we only use nil-terminated strings or
559 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.

588 2006-10-21 Paul Smith <psmith@gnu.org>
591 * arscan.c: Constified.
593 2006-09-30 Paul Smith <psmith@gnu.org>

655 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
656 that don't have extended grep.
657 (cvsclean): Use $(PERL) instead of perl.
659 2006-04-09 Paul D. Smith <psmith@gnu.org>

725 Declare and define sh_chars_sh[].
727 2006-03-23 Paul D. Smith <psmith@gnu.org>
729 * configure.in: Look for build.sh.in in $srcdir so it will be
730 built for remote configurations as well.
732 * Makefile.am: Make sure to clean up build.sh during distclean.
733 Fixes Savannah bug #16166.
735 * misc.c (log_access): Takes a const char *.
736 * function.c (fold_newlines): Takes an unsigned int *.
737 Both fixes for Savannah bug #16170.

748 memory on hosts that don't support it directly.
750 * README.cvs: Add information on steps for making a release (to
751 make sure I don't forget any).
753 * main.c (clean_jobserver): Move jobserver cleanup code into a new
755 (die): Cleanup code was removed from here; call the new function.
756 (main): If we are re-execing, clean up the jobserver first so we
757 don't leak file descriptors.
758 Reported by Craig Fithian <craig.fithian@citigroup.com>
760 2006-03-17 Paul D. Smith <psmith@gnu.org>

769 * misc.c (alloc_dep, free_dep): New functions.
770 (copy_dep_chain): Copy stem.
771 (free_dep_chain): Use free_dep.
772 * read.c (record_files): Store stem in the dependency line.
773 * file.c (expand_deps): Use stem stored in the dependency line. Use

786 (allocated_variable_append): Don't expand the final result.
787 Fixes Savannah bug #15913.
789 2006-03-09 Paul Smith <psmith@gnu.org>
791 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
792 listed non-existent files as changed. Turns out there's a bug in
793 the Linux kernel builds which means that this change causes
794 everything to rebuild every time. We will re-introduce this fix
795 in the next release, to give them time to fix their build system.
796 Fixes Savannah bug #16002.
797 Introduces Savannah bug #16051.
799 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
800 we *don't* find UNIX "/".

812 to be null; don't core in that case.
814 2006-02-19 Paul D. Smith <psmith@gnu.org>
816 * commands.c (set_file_variables): Realloc, not malloc, the static
817 string values to avoid memory leaks.
819 * expand.c (recursively_expand_for_file): Only set reading_file to
820 an initialized value.
822 * implicit.c (pattern_search): We need to make a copy of the stem
823 if we get it from an intermediate dep, since those get freed.
825 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
827 (enter_file) [VMS]: Ditto.
828 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
830 2006-02-24 Eli Zaretskii <eliz@gnu.org>
832 * job.c (construct_command_argv_internal): Fix last change.
834 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
835 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
836 the calls to _beginthreadex.
838 * expand.c (recursively_expand_for_file): Initialize `save' to
839 prevent compiler warnings.
841 2006-02-18 Eli Zaretskii <eliz@gnu.org>
843 * job.c (construct_command_argv_internal): Don't create a temporary
844 script/batch file if we are under -n. Call _setmode to switch the
845 script file stream to text mode.
847 2006-02-17 Paul D. Smith <psmith@gnu.org>
849 * variable.c (merge_variable_set_lists): Don't try to merge the
850 global_setlist. Not only is this useless, but it can lead to
851 circularities in the linked list, if global_setlist->next in one
852 list gets set to point to another list which also ends in
854 Fixes Savannah bug #15757.
856 2006-02-15 Paul D. Smith <psmith@gnu.org>
858 Fix for Savannah bug #106.
860 * expand.c (expanding_var): Keep track of which variable we're
861 expanding. If no variable is being expanded, it's the same as
863 * make.h (expanding_var): Declare it.
864 * expand.c (recursively_expand_for_file): Set expanding_var to the
865 current variable we're expanding, unless there's no file info in
866 it (could happen if it comes from the command line or a default
867 variable). Restore it before we exit.
868 * expand.c (variable_expand_string): Use the expanding_var file
869 info instead of the reading_file info.

875 (handle_function): Ditto.

879 * read.c (eval): Even if the included filenames expands to the
880 empty string we still need to free the allocated buffer.
882 * implicit.c (pattern_search): If we allocated a variable set for
883 an impossible file, free it.
884 * variable.c (free_variable_set): New function.
885 * variable.h: Declare it.
887 * read.c (read_all_makefiles): Makefile names are kept in the
888 strcache, so there's never any need to alloc/free them.
891 * main.c (main): Add "archives" to the .FEATURES variable if
892 archive support is enabled.
893 * doc/make.texi (Special Variables): Document it.
895 2006-02-13 Paul D. Smith <psmith@gnu.org>
897 * implicit.c (pattern_search): Add checking for DOS pathnames to
898 the pattern rule target LASTSLASH manipulation.

903 * (ALL FILES): Updated copyright and license notices.
905 2006-02-10 Paul D. Smith <psmith@gnu.org>
907 A new internal capability: the string cache is a read-only cache
908 of strings, with a hash table interface for fast lookup. Nothing
909 in the cache will ever be freed, so there's no need for reference
910 counting, etc. This is the beginning of a full solution for
911 Savannah bug #15182, but for now we only store makefile names here.
913 * strcache.c: New file. Implement a read-only string cache.
914 * make.h: Add prototypes for new functions.
915 * main.c (initialize_global_hash_tables): Initialize the string cache.
916 (print_data_base): Print string cache stats.

922 * dir.c (dir_contents_file_exists_p): Don't opendir if the
923 directory time stamp didn't change, except on FAT filesystems.
924 Suggested by J. David Bryan <jdbryan@acm.org>.
926 2006-02-09 Paul D. Smith <psmith@gnu.org>
928 * function.c (func_or): Implement a short-circuiting OR function.
929 (func_and): Implement a short-circuiting AND function.
930 (function_table_init): Update the table with the new functions.
931 * doc/make.texi (Conditional Functions): Changed the "if" section
932 to one on general conditional functions. Added documentation for
933 $(and ...) and $(or ...) functions.
934 * NEWS: Note new $(and ...) and $(or ...) functions.
936 2006-02-08 Boris Kolpackov <boris@kolpackov.net>

941 one in struct file. Fixes Savannah bug #15641.
943 2006-02-06 Paul D. Smith <psmith@gnu.org>
945 * vpath.c (selective_vpath_search): If the file we find has a
946 timestamp from -o or -W, use that instead of the real time.
947 * remake.c (f_mtime): If the mtime is a special token from -o or
948 -W, don't overwrite it with the real mtime.

962 2006-02-05 Paul D. Smith <psmith@gnu.org>
964 * file.c (enter_file): Keep track of the last double_colon entry,
965 to avoid walking the list every time we want to add a new one.
966 Fixes Savannah bug #15533.
967 * filedef.h (struct file): Add a new LAST pointer.
969 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
970 the comparison. For 64-bits systems the result of the subtraction
971 might not fit into an int. Use comparison instead.
972 Fixes Savannah bug #15534.
974 * doc/make.texi: Update the chapter on writing commands to reflect
975 the changes made in 3.81 for backslash/newline and SHELL handling.

995 2006-01-21 Eli Zaretskii <eliz@gnu.org>
997 * remake.c (update_goal_chain): Set g->changed instead of
998 incrementing it, as it is only 8-bit wide, and could overflow if
999 many commands got started in update_file.
1001 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1003 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1014 the load were too high.
1015 (start_job_command): Fix a typo in error message when process_easy
1018 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1020 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1021 the shell is not sh.exe.
1023 * job.c (create_batch_file): Renamed from create_batch_filename;
1024 all callers changed. Don't close the temporary file; return its
1025 file descriptor instead. New arg FD allows to return the file
1027 (construct_command_argv_internal): Use _fdopen instead of fopen to
1028 open the batch file.
1030 2006-01-04 Paul D. Smith <psmith@gnu.org>
1032 * readme.vms: Updates for case-insensitive VMS file systems from

1059 * doc/make.texi (Execution): Add a footnote about changes in
1060 handling of backslash-newline sequences. Mention the differences
1061 on MS-DOS and MS-Windows.
1063 * NEWS: More details about building the MinGW port and a pointer
1064 to README.W32. Fix the section name that describes the new
1065 backward-incompatible processing of backslash-newline sequences.
1066 The special processing of SHELL set to "cmd" is only relevant to
1067 MS-Windows, not MS-DOS.
1069 2005-12-17 Eli Zaretskii <eliz@gnu.org>

1072 to DWORD, to avoid compiler warnings.

1083 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1084 (Shell Function, Target-specific): Add @: after "vs."
1086 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1088 * read.c (record_target_var): Initialize variable's export field
1089 with v_default instead of leaving it "initialized" by whatever
1090 garbage happened to be on the heap.
1092 2005-12-12 Paul D. Smith <psmith@gnu.org>
1094 * make.1: Fix some display errors and document all existing options.
1095 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1097 2005-12-11 Paul D. Smith <psmith@gnu.org>
1099 * implicit.c (pattern_search): If 2nd expansion is not set for
1100 this implicit rule, replace the pattern with the stem directly,
1101 and don't re-expand the variable list. Along with the other
1102 .SECONDEXPANSION changes below, fixes bug #13781.
1104 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1106 * implicit.c (pattern_search): Mark other files that this rule
1107 builds as targets so that they are not treated as intermediates
1108 by the pattern rule search algorithm. Fixes bug #13022.
1110 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1112 * remake.c (notice_finished_file): Propagate the change of
1113 modification time to all the double-colon entries only if
1114 it is the last one to be updated. Fixes bug #14334.
1116 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1118 * function.c (func_flavor): Implement the flavor function which
1119 returns the flavor of a variable.
1120 * doc/make.texi (Functions for Transforming Text): Document it.
1121 * NEWS: Add it to the list of new functions.
1123 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1125 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1127 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1128 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1130 2005-10-26 Paul Smith <psmith@gnu.org>
1132 * read.c (record_files): Don't set deps flags if there are no deps.
1133 * maintMakefile: We only need to build the templates when we are
1134 creating a distribution, so don't do it for "all".
1136 2005-10-24 Paul D. Smith <psmith@gnu.org>
1138 Make secondary expansion optional: its enabled by declaring the
1139 special target .SECONDEXPANSION.
1141 * NEWS: Update information on second expansion capabilities.
1142 * doc/make.texi (Secondary Expansion): Document the
1143 .SECONDEXPANSION special target and its behavior.
1144 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1145 prerequisite list was found in a static pattern rule.
1146 (free_dep_chain): Declare a prototype.
1147 * file.c (parse_prereqs): New function: break out some complexity
1149 (expand_deps): If we aren't doing second expansion, replace % with
1150 the stem for static pattern rules. Call the new function.
1151 * filedef.h (parse_prereqs): Declare a prototype.
1152 * implicit.c (pattern_search): Initialize the new staticpattern
1154 * main.c (second_expansion): Declare a global variable to remember
1155 if the special target has been seen. Initialize the new
1156 staticpattern field for prerequisites.
1157 * make.h: Extern for second_expansion.
1158 * misc.c (free_dep_chain): New function: frees a struct dep list.
1159 * read.c (read_all_makefiles): Initialize the staticpattern field.
1160 (eval_makefile): Ditto.
1161 (record_files): Check for the .SECONDEXPANSION target and set
1162 second_expansion global if it's found.
1163 Use the new free_dep_chain() instead of doing it by hand.
1164 Set the staticpattern field for prereqs of static pattern targets.
1166 2005-10-16 Paul D. Smith <psmith@gnu.org>
1168 * main.c (main): Set CURDIR to be a file variable instead of a
1169 default, so that values of CURDIR inherited from the environment
1170 won't override the make value.
1172 2005-09-26 Paul D. Smith <psmith@gnu.org>
1174 * job.c (construct_command_argv_internal): If the line is empty
1175 remember to free the temporary argv strings.
1178 2005-09-16 Paul D. Smith <psmith@gnu.org>
1180 * job.c (start_job_command): The noerror flag is a boolean (single
1181 bit); set it appropriately.
1182 Reported by Mark Eichin <eichin@metacarta.com>
1184 2005-08-29 Paul D. Smith <psmith@gnu.org>
1186 * function.c (func_error): On Windows, output from $(info ...)
1187 seems to come in the wrong order. Try to force it with fflush().
1189 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1191 * read.c (record_files): Move code that sets stem for static
1192 pattern rules out of the if (!two_colon) condition so it is
1193 also executed for two-colon rules. Fixes Savannah bug #13881.
1195 2005-08-08 Paul D. Smith <psmith@gnu.org>
1197 * make.h: Don't test that __STDC__ is non-0. Some compilers
1198 (Windows for example) set it to 0 to denote "ISO C + extensions".
1201 2005-08-07 Paul D. Smith <psmith@gnu.org>
1203 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1204 conditional (slightly different version of a fix from Eli).
1206 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1207 If make is running in parallel without -k and two jobs die in a
1208 row, but not too close to each other, then make will quit without
1209 waiting for the rest of the jobs to die.
1211 * main.c (die): Don't reset err before calling reap_children() the
1212 second time: we still want it to be in the error condition.
1213 * job.c (reap_children): Use a static variable, rather than err,
1214 to control whether or not the error message should be printed.
1216 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1218 * w32/subproc/sub_proc.c: Include signal.h.
1219 (process_pipe_io, process_file_io): Pass a pointer to a local
1220 DWORD variable to GetExitCodeProcess. If the exit code is
1221 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1223 * job.c [WINDOWS32]: Include windows.h.
1224 (main_thread) [WINDOWS32]: New global variable.
1225 (reap_children) [WINDOWS32]: Get the handle for the main thread
1226 and store it in main_thread.
1228 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1229 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1230 doing anything else. When we are done, close the main thread
1231 handle and exit with status 130.
1233 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1235 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1238 * main.c (find_and_set_default_shell): If found a DOSish shell,
1239 set sh_found and the value of default_shell, and report the
1240 findings in debug mode.
1242 * job.c (construct_command_argv_internal): Check unixy_shell, not
1243 no_default_sh_exe, to decide whether to use Unixy or DOSish
1246 * README.W32: Update with info about the MinGW build.
1248 * build_w32.bat: Support MinGW.
1250 * w32/subproc/build.bat: Likewise.
1252 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1253 printing DWORD args.
1255 * function.c (windows32_openpipe): Fix format strings for printing
1258 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1260 (start_job_command): Fix format string for printing the result of
1262 (start_job_command) [WINDOWS32]: Do not define.
1263 (exec_command): Fix format string for printing HANDLE args.
1265 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1266 to avoid compiler warnings.
1267 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1268 (Note: some of these fixes were submitted independently by J. Grant)
1270 2005-07-30 J. Grant <jg@jguk.org>
1272 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1273 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1274 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1276 2005-07-15 Paul Smith <psmith@gnu.org>
1278 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1279 we don't have a POSIX shell, then revert to the old
1280 backslash-newline behavior (where they are stripped).
1283 2005-07-08 Paul D. Smith <psmith@gnu.org>
1285 * config.h.W32.template: Reorder to match the standard config.h,
1286 for easier comparisons.
1287 From J. Grant <jg@jguk.org>
1289 * maintMakefile: Remove .dep_segment before overwriting it, in
1290 case it's not writable or noclobber is set.
1291 * expand.c (variable_expand_string): Cast result of pointer
1292 arithmetic to avoid a warning.
1293 * main.c (switches): Add full-fledged final initializer.
1295 2005-07-06 Paul D. Smith <psmith@gnu.org>
1297 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1298 * signame.c (strsignal): If we found _sys_siglist[] or
1299 __sys_siglist[] use those instead of sys_siglist[].
1300 From Albert Chin <china@thewrittenword.com>
1302 2005-07-04 Paul D. Smith <psmith@gnu.org>
1304 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1305 globfree(); set up to use the GNU versions.
1306 From Martin Zinser <zinser@zinser.no-ip.info>
1308 2005-07-03 Paul D. Smith <psmith@gnu.org>
1310 From J. Grant <jg@jguk.org>:
1312 * README.W32.template: Update the Windows and tested MSVC versions.
1313 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1314 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1315 * build_w32.bat: Ditto.
1316 * w32/subproc/build.bat: Ditto.
1318 2005-06-28 Paul D. Smith <psmith@gnu.org>
1320 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1321 declaration was checked but not present.
1323 2005-06-27 Paul D. Smith <psmith@gnu.org>
1325 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1326 to unsigned long. Fixes Savannah bug #13550.
1328 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1329 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1330 Fixes Savannah bug #13551.
1332 2005-06-26 Paul D. Smith <psmith@gnu.org>
1334 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1335 it if ANSI_STRING is not set.
1337 2005-06-25 Paul D. Smith <psmith@gnu.org>
1339 * read.c (eval): If no filenames are passed to any of the
1340 "include" variants, don't print an error.
1341 * doc/make.texi (Include): Document this.
1342 Fixes Savannah bug #1761.
1344 * job.c (construct_command_argv_internal): Sanitize handling of
1345 backslash/newline pairs according to POSIX: that is, keep the
1346 backslash-newline in the command script, but remove a following
1347 TAB character, if present. In the fast path, make sure that the
1348 behavior matches what the shell would do both inside and outside
1349 of quotes. In the slow path, quote the backslash and put a
1350 literal newline in the string.
1351 Fixes Savannah bug #1332.
1352 * doc/make.texi (Execution): Document the new behavior and give
1354 * NEWS: Make a note of the new behavior.
1356 * make.h [WINDOWS32]: #include <direct.h>.
1357 Fixes Savannah bug #13478.
1359 * remake.c (name_mtime): If the stat() of a file fails and the -L
1360 option was given and the file is a symlink, take the best mtime of
1361 the symlink we can get as the mtime of the file and don't fail.
1362 Fixes Savannah bug #13280.
1364 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1365 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1366 inside a variable reference. Make this function static as it's
1368 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1369 parsing an unexpanded line looking for semicolons.
1370 Fixes Savannah bug #1454.
1371 * misc.c (remove_comments): Move this to read.c and make it static
1372 as it's only used there. Call find_char_unquote() with new arg.
1373 * make.h: Remove prototypes for find_char_unquote() and
1374 remove_comments() since they're static now.
1376 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1377 its export flag and obtain its value. When we need to re-exec,
1378 increment the value and add it into the environment.
1379 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1380 * NEWS: Mention MAKE_RESTARTS.
1381 * main.c (always_make_set): New variable. Change the -B option to
1382 set this one instead.
1383 (main): When checking makefiles, only set always_make_flag if
1384 always_make_set is set AND the restarts flag is 0. When building
1385 normal targets, set it IFF always_make_set is set.
1386 (main): Avoid infinite recursion with -W, too: only set what-if
1387 files to NEW before we check makefiles if we've never restarted
1388 before. If we have restarted, set what-if files to NEW _after_ we
1390 Fixes Savannah bug #7566:
1392 2005-06-17 Paul D. Smith <psmith@gnu.org>
1394 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1395 in the prerequisites list.
1397 2005-06-12 Paul D. Smith <psmith@gnu.org>
1399 Fix Savannah bug # 1328.
1401 * configure.in: Check for atexit().
1402 * misc.c (close_stdout): Test stdout to see if writes to it have
1403 failed. If so, be sure to exit with a non-0 error code. Based on
1404 code found in gnulib.
1405 * make.h: Prototype.
1406 * main.c (main): Install close_stdout() with atexit().
1408 2005-06-10 Paul D. Smith <psmith@gnu.org>
1410 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1412 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1413 headers; make vmsWaitForChildren() static; extern vmsify().
1414 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1415 Don't create child_execute_job() here (it's in vmsjobs.c).
1416 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1418 2005-06-09 Paul D. Smith <psmith@gnu.org>
1420 * variable.c (push_new_variable_scope): File variables point
1421 directly to the global_setlist variable. So, inserting a new
1422 scope in front of that has no effect on those variables: they
1423 don't go through current_variable_set_list. If we're pushing a
1424 scope and the current scope is global, push it "the other way" so
1425 that the new setlist is in the global_setlist variable, and
1426 next points to a new setlist with the global variable set.
1427 (pop_variable_scope): Properly undo a push with the new
1429 Fixes Savannah bug #11913.
1431 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1433 * job.c (reap_children): Don't die of the command failed but
1434 the dontcare flag is set. Fixes Savannah bug #13216.
1436 * implicit.c (pattern_search): When creating a target from
1437 an implicit rule match, lookup pattern target and set precious
1438 flag in a newly created target. Fixes Savannah bug #13218.
1440 2005-05-13 Paul D. Smith <psmith@gnu.org>
1442 Implement "if... else if... endif" syntax.
1444 * read.c (eval): Push all checks for conditional words ("ifeq",
1445 "else", etc.) down into the conditional_line() function.
1446 (conditional_line): Rework to allow "else if..." clause. New
1447 return value -2 for lines which are not conditionals. The
1448 ignoring flag can now also be 2, which means "already parsed a
1449 true branch". If that value is seen no other branch of this
1450 conditional can be considered true. In the else parsing if there
1451 is extra text after the else, invoke conditional_line()
1452 recursively to see if it's another conditional. If not, it's an
1453 error. If so, raise the conditional value to this level instead
1454 of creating a new conditional nesting level. Special check for
1455 "else" and "endif", which aren't allowed on the "else" line.
1456 * doc/make.texi (Conditional Syntax): Document the new syntax.
1458 2005-05-09 Paul D. Smith <psmith@gnu.org>
1460 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1461 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1462 recurses to the w32 directory, even on non-Windows systems. Use
1463 the method suggested in the automake manual.
1464 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1465 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1467 2005-05-07 Paul D. Smith <psmith@gnu.org>
1469 * main.c (die): If we're dying with a fatal error (not that a
1470 command has failed), write back any leftover tokens before we go.
1472 * job.c (set_child_handler_action_flags): If there are jobs
1473 waiting for the load to go down, set an alarm to go off in 1
1474 second. This allows us to wake up from a potentially long-lasting
1475 read() and start a new job if the load has gone down. Turn it off
1477 (job_noop): Dummy signal handler function.
1478 (new_job): Invoke it with the new semantics.
1480 * docs/make.texi: Document secondary expansion. Various cleanups
1483 2005-05-03 Paul D. Smith <psmith@gnu.org>
1485 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1486 the targets which are to ultimately be made are called "goals";
1487 see the GNU make manual. Also, MAKECMDGOALS, etc.
1489 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1490 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1491 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1493 2005-05-02 Paul D. Smith <psmith@gnu.org>
1495 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1496 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1497 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1498 functions to vmsjobs.c. #include it into jobs.c.
1500 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1501 jobserver tokens. I found that this happens when an exported
1502 recursive variable contains a $(shell ...) function reference: in
1503 this situation we could "forget" to write back a token.
1505 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1506 we have. It's not reliable to depend on the number of children in
1507 our linked list so keep a separate count.
1508 (new_job): Check jobserver_tokens rather than children &&
1509 waiting_jobs. Increment jobserver_tokens when we get one.
1510 (free_child): If jobserver_tokens is 0, internal error. If it's
1511 >1, write a token back to the jobserver pipe (we don't write a
1512 token for the "free" job). Decrement jobserver_tokens.
1514 * main.c: Add variable master_job_slots.
1515 (main): Set it to hold the number of jobs requested if we're the
1516 master process, when using the jobserver.
1517 (die): Sanity checks: first test jobserver_tokens to make sure
1518 this process isn't holding any tokens we didn't write back.
1519 Second, if master_job_slots is set count the tokens left in the
1520 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1522 2005-04-24 Paul D. Smith <psmith@gnu.org>
1524 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1525 with -l# can lose jobserver tokens, because waiting jobs are not
1526 consulted properly when checking for the "free" token.
1528 * job.c (free_child): Count waiting_jobs as having tokens.
1529 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1530 handle jobs waiting for the load to drop.
1532 2005-04-23 Paul D. Smith <psmith@gnu.org>
1534 * main.c (main): Be careful to not core if a variable setting in
1535 the environment doesn't contain an '='. This is illegal but can
1536 happen in broken setups.
1537 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1539 2005-04-12 Paul D. Smith <psmith@gnu.org>
1541 The second expansion feature causes significant slowdown. Timing
1542 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1543 read the makefile before the feature, to 11+s to do the same
1544 operations after the feature. Additionally, memory usage
1545 increased drastically. To fix this I added some intelligence that
1546 avoids the overhead of the second expansion unless it's required.
1548 * dep.h: Add a new boolean field, need_2nd_expansion.
1550 * read.c (eval): When creating the struct dep for the target,
1551 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1552 (record_files): If there's a "%" in a static pattern rule, it gets
1553 converted to "$*" so set need_2nd_expansion to 1.
1555 * file.c (expand_deps): Rework to be more efficient. Only perform
1556 initialize_file_variables(), set_file_variables(), and
1557 variable_expand_for_file() if the need_2nd_expansion is set.
1559 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1560 (pattern_search): Ditto.
1561 * main.c (handle_non_switch_argument): Ditto.
1563 * read.c (read_all_makefiles): Ditto.
1564 (eval_makefile): Ditto.
1566 2005-04-07 Paul D. Smith <psmith@gnu.org>
1568 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1569 * variable.c (sync_Path_environment): Ditto.
1570 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1572 * main.c (main): Define the .FEATURES variable.
1573 * NEWS: Announce .FEATURES.
1574 * doc/make.texi (Special Variables): Document .FEATURES.
1576 * remake.c (check_dep): If a file is .PHONY, update it even if
1577 it's marked intermediate. Fixes Savannah bug #12331.

1581 * file.c (expand_deps): Factor out the second expansion and
1582 prerequisite line parsing logic from snap_deps().
1584 * file.c (snap_deps): Use expand_deps(). Expand and parse
1585 prerequisites of the .SUFFIXES special target first. Fixes
1586 Savannah bug #12320.
1588 2005-03-13 Paul D. Smith <psmith@gnu.org>
1590 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1593 2005-03-11 Paul D. Smith <psmith@gnu.org>
1595 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1596 available, not undefined (from Earnie Boyd).
1598 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1600 * implicit.c (pattern_search): Mark an intermediate target as
1601 precious if it happened to be a prerequisite of some (other)
1602 target. Fixes Savannah bug #12267.
1604 2005-03-09 Paul D. Smith <psmith@gnu.org>
1606 * read.c (eval_makefile): Add alloca(0).
1607 (eval_buffer): Ditto.
1609 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1611 * main.c (main): Use o_file instead of o_default when defining
1612 the .DEFAULT_TARGET special variable.
1613 * read.c (eval): Use define_variable_global() instead of
1614 define_variable() when setting new value for the .DEFAULT_TARGET
1615 special variable. Fixes Savannah bug #12266.
1617 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1619 * imlicit.c (pattern_search): Mark files for which an implicit
1620 rule has been found as targets. Fixes Savannah bug #12202.
1622 2005-03-04 Paul D. Smith <psmith@gnu.org>
1625 * doc/make.texi (Automatic Variables): Document $|.
1627 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1629 * read.c (record_files): Instead of substituting % with
1630 actual stem value in dependency list replace it with $*.
1631 This fixes stem triple expansion bug.
1633 * implicit.c (pattern_search): Copy stem to a separate
1634 buffer and make it a properly terminated string. Assign
1635 this buffer instead of STEM (which is not terminated) to
1636 f->stem. Instead of substituting % with actual stem value
1637 in dependency list replace it with $*. This fixes stem
1638 triple expansion bug.
1640 2005-03-01 Paul D. Smith <psmith@gnu.org>
1642 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1643 on Windows, as it takes a handle not a pid. Just exit.
1644 Fix from patch #3679, provided by Alessandro Vesely.
1646 * configure.in: Update check for sys_siglist[] from autoconf manual.
1647 * signame.c (strsignal): Update to use the new autoconf macro.
1649 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1651 * read.c (record_files): Add a check for the list of prerequisites
1652 of a static pattern rule being empty. Fixes Savannah bug #12180.
1654 2005-02-28 Paul D. Smith <psmith@gnu.org>
1656 * doc/make.texi (Text Functions): Update docs to allow the end
1657 ordinal for $(wordlist ...) to be 0.
1658 * function.c (func_wordlist): Fail if the start ordinal for
1659 $(wordlist ...) is <1. Matches documentation.
1660 Resolves Savannah support request #103195.
1662 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1663 previously we were stopping when !-q, exactly the opposite. This
1664 has been wrong since version 1.34, in 1994!
1665 (update_file): If we got an error don't break out to run more
1666 double-colon rules: just return immediately.
1667 Fixes Savannah bug #7144.
1669 2005-02-27 Paul D. Smith <psmith@gnu.org>
1671 * misc.c (end_of_token): Make argument const.
1672 * make.h: Update prototype.
1674 * function.c (abspath, func_realpath, func_abspath): Use
1675 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1676 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1677 * read.c (record_files): Ditto.
1678 * variable.c (do_variable_definition): Ditto.
1680 * function.c (func_error): Create a new function $(info ...) that
1681 simply prints the message to stdout with no extras.
1682 (function_table_init): Add new function to the table.
1683 * NEWS: Add $(info ...) reference.
1684 * doc/make.texi (Make Control Functions): Document it.
1686 New feature: if the system supports symbolic links, and the user
1687 provides the -L/--check-symlink-time flag, then use the latest
1688 mtime between the symlink(s) and the target file.
1690 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1691 readlink(). If both are available, define MAKE_SYMLINKS.
1692 * main.c: New variable: check_symlink_flag.
1693 (usage): Add a line for -L/--check-symlink-times to the help string.
1694 (switches): Add -L/--check-symlink-times command line argument.
1695 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1696 print a warning and disable it again.
1697 * make.h: Declare check_symlink_flag.
1698 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1699 if the file is a symlink then check each link in the chain and
1700 choose the NEWEST mtime we find as the mtime for the file. The
1701 newest mtime might be the file itself!
1702 * NEWS: Add information about this new feature.
1703 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1705 Avoid core dumps described in Savannah bug # 12124:
1707 * file.c: New variable snapped_deps remember whether we've run
1709 (snap_deps): Set it.
1710 * filedef.h: Extern it.
1711 * read.c (record_files): Check snapped_deps; if it's set then
1712 we're trying to eval a new target/prerequisite relationship from
1713 within a command script, which we don't support. Fatal.
1715 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1717 Implementation of the .DEFAULT_TARGET special variable.
1719 * read.c (eval): If necessary, update default_target_name when
1721 * read.c (record_files): Update default_target_file if
1722 default_target_name has changed.
1723 * main.c (default_target_name): Define.
1724 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1725 default_target_name is set use default_target_file as a root
1727 * filedef.h (default_target_name): Declare.
1728 * dep.h (free_dep_chain):
1729 * misc.c (free_dep_chain): Change to operate on struct nameseq
1730 and change name to free_ns_chain.
1731 * file.c (snap_deps): Update to use free_ns_chain.
1733 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1735 Implementation of the second expansion in explicit rules,
1736 static pattern rules and implicit rules.
1738 * read.c (eval): Refrain from chopping up rule's dependencies.
1739 Store them in a struct dep as a single dependency line. Remove
1740 the code that implements SySV-style automatic variables.
1742 * read.c (record_files): Adjust the code that handles static
1743 pattern rules to expand all percents instead of only the first
1744 one. Reverse the order in which dependencies are stored so that
1745 when the second expansion reverses them again they appear in
1746 the makefile order (with some exceptions, see comments in
1747 the code). Remove the code that implements SySV-style automatic
1750 * file.c (snap_deps): Implement the second expansion and chopping
1751 of dependency lines for explicit rules.
1753 * implicit.c (struct idep): Define an auxiliary data type to hold
1754 implicit rule's dependencies after stem substitution and
1757 * implicit.c (free_idep_chain): Implement.
1759 * implicit.c (get_next_word): Implement helper function for
1760 parsing implicit rule's dependency lines into words taking
1761 into account variable expansion requests. Used in the stem
1764 * implicit.c (pattern_search): Implement the second expansion
1765 for implicit rules. Also fixes bug #12091.
1767 * commands.h (set_file_variables): Declare.
1768 * commands.c (set_file_variables): Remove static specifier.
1770 * dep.h (free_dep_chain): Declare.
1771 * misc.c (free_dep_chain): Implement.
1773 * variable.h (variable_expand_for_file): Declare.
1774 * expand.c (variable_expand_for_file): Remove static specifier.
1776 * make.h (strip_whitespace): Declare.
1777 * function.c (strip_whitespace): Remove static specifier.
1779 2005-02-26 Paul D. Smith <psmith@gnu.org>
1781 * main.c (main): Check for ferror() when reading makefiles from stdin.
1782 Apparently some shells in Windows don't close pipes properly and
1785 2005-02-24 Jonathan Grant <jg@jguk.org>
1787 * configure.in: Add MinGW configuration options, and extra w32 code
1789 * Makefile.am: Add MinGW configuration options, and extra w32 code
1791 * main.c: Determine correct program string (after last \ without .exe).
1792 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1794 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1795 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1796 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1797 environment support.
1799 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1801 * function.c (func_shell): When initializing error_prefix, check
1802 that reading file name is not null. This fixes long-standing
1803 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1805 2005-02-09 Paul D. Smith <psmith@gnu.org>
1807 * maintMakefile: Update the CVS download URL to simplify them.
1808 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1809 downloading the .texi files from Savannah now.
1811 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1813 * main.c (handle_non_switch_argument): Only add variables to
1814 command_variables if they're not already there: duplicate settings
1815 waste space and can be confusing to read.
1817 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1818 this header is never included by non-WINDOWS32 code, and it
1819 requires <config.h> to define which isn't always included first.
1821 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1822 testing MINGW32 versions.
1824 * main.c (log_working_directory): flush stdout to be sure the WD
1825 change is printed before any stderr messages show up.
1827 2005-02-01 Paul D. Smith <psmith@gnu.org>
1829 * maintMakefile (po_repo): Update the GNU translation site URL.
1831 2004-12-01 Paul D. Smith <psmith@gnu.org>
1833 * main.c (main): Change char* env_shell to struct variable shell_var.
1834 * variable.c (target_environment): Use new shell_var.
1836 2004-11-30 Paul D. Smith <psmith@gnu.org>
1838 * configure.in: The old way we avoided creating build.sh from
1839 build.sh.in before build.sh.in exists doesn't work anymore; we
1840 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1841 the help!). This also keeps automake from complaining.
1842 * Makefile.am (README): Add a dummy target so automake won't
1843 complain that this file doesn't exist when we checkout from CVS.
1844 * maintMakefile (.dep_segment): Rewrite this rule since newer
1845 versions of automake don't provide DEP_FILES.
1847 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1849 Implementation of `realpath' and `abspath' built-in functions.
1851 * configure.in: Check for realpath.
1852 * function.c (abspath): Return an absolute file name that does
1853 not contain any `.' or `..' components, nor repeated `/'.
1854 * function.c (func_abspath): For each name call abspath.
1855 * function.c (func_realpath): For each name call realpath
1856 from libc or delegate to abspath if realpath is not available.
1857 * doc/make.texi (Functions for File Names): Document new functions.
1858 * doc/make.texi (Quick Reference): Ditto.
1860 2004-11-28 Paul D. Smith <psmith@gnu.org>
1862 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1863 arguments. Fixes bug #10252.
1865 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1867 * main.c (main): Set SHELL to v_noexport by default. Remember the
1868 original environment setting of SHELL in the env_shell variable.
1869 * main.h: Export new env_shell variable.
1870 * variable.c (target_environment): If we find a v_noexport
1871 variable for SHELL, add a SHELL variable with the env_shell value.
1872 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1873 * doc/make.texi (Variables/Recursion): Ditto.
1875 2004-11-28 Paul D. Smith <psmith@gnu.org>
1877 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1878 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1879 Patch by Alessandro Vesely.
1881 2004-11-12 Paul D. Smith <psmith@gnu.org>
1883 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1884 the command line if it's inside a string.
1885 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1887 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1889 * function.c (func_lastword): New function: return last word
1890 from the list of words.
1891 * doc/make.texi: Document $(lastword ). Fix broken links in
1892 Quick Reference section.
1894 2004-10-06 Paul D. Smith <psmith@gnu.org>
1896 Apply patch from Alessandro Vesely, provided with bug # 9748.
1897 Fix use of tmpnam() to work with Borland C.
1899 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1900 construction of a temporary filename, and call new function
1901 create_batch_filename().
1902 (create_batch_filename) [WINDOWS32]: New function to create a
1905 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1907 * read.c (record_target_var): Expand simple pattern-specific
1909 * variable.c (initialize_file_variables): Do not expand simple
1910 pattern-specific variable.
1912 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1914 * remake.c (update_file_1): When rebuilding makefiles inherit
1915 dontcare flag from a target that triggered update.
1917 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1919 * variable.c (initialize_file_variables): Mark pattern-specific
1920 variable as a per-target and copy export status.
1922 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1924 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1926 * implicit.c (pattern_search): When considering an implicit rule's
1927 prerequisite check that it is actually a target rather then
1928 just an entry in the file hashtable.
1930 2004-09-21 Paul D. Smith <psmith@gnu.org>
1932 * read.c (readstring): Fix some logic errors in backslash handling.
1933 (eval): Remove some unnecessary processing in buffer handling.
1934 (record_target_var): Assert that parse_variable_definition() succeeded.
1935 Reported by: Markus Mauhart <qwe123@chello.at>.
1937 * misc.c: Removed the sindex() function. All instances of this
1938 function were trivially replaceable by the standard strstr()
1939 function, and that function will always have better (or certainly
1940 no worse) performance than the very simple-minded algorithm
1941 sindex() used. This can matter with complex makefiles.
1942 * make.h: Remove the prototype for sindex().
1943 * function.c (subst_expand): Convert sindex() call to strstr().
1944 This means we no longer need to track the TLEN value so remove that.
1945 (func_findstring): Convert sindex() to strstr().
1946 * commands.c (chop_commands): Convert sindex() calls to strstr().
1947 Suggested by: Markus Mauhart <qwe123@chello.at>.
1949 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1950 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1951 If SHELL is set to CMD.EXE then assume it's batch-mode and
1952 non-unixy. I wrote the code differently from the patch, though,
1953 to make it safer. This also resolves bug #9174.
1955 2004-09-20 Paul D. Smith <psmith@gnu.org>
1957 * expand.c (variable_expand_string): Modify to invoke
1958 patsubst_expand() instead of subst_expand(); the latter didn't
1959 handle suffix patterns correctly.
1960 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1961 was used only from variable_expand_string() and is no longer used
1963 (func_subst): Ditto, on call to subst_expand().
1964 (patsubst_expand): Require the percent pointers to point to the
1965 character after the %, not to the % itself.
1966 * read.c (record_files): New call criteria for patsubst_expand().
1967 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1968 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1970 2004-09-19 Paul D. Smith <psmith@gnu.org>
1972 * function.c (subst_expand): Fix a check in by_word: look for a
1973 previous blank if we're beyond the beginning of the string, not
1974 the beginning of the word.
1975 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1977 2004-05-16 Paul D. Smith <psmith@gnu.org>
1979 * remake.c (update_goal_chain): Change the argument specifying
1980 whether we're rebuilding makefiles to be a global variable,
1981 REBUILDING_MAKEFILES.
1982 (complain): Extract the code that complains about no rules to make
1983 a target into a separate function.
1984 (update_file_1): If we tried to rebuild a file during the makefile
1985 rebuild phase and it was dontcare, then no message was printed.
1986 If we then try to build the same file during the normal build,
1987 print a message this time.
1988 (remake_file): Don't complain about un-remake-able files when
1989 we're rebuilding makefiles.
1991 2004-05-11 Paul D. Smith <psmith@gnu.org>
1993 * job.c (construct_command_argv_internal): OS/2 patches from
1994 Andreas Buening <andreas.buening@nexgo.de>.
1996 2004-05-10 Paul D. Smith <psmith@gnu.org>
1998 * remake.c (update_file): Don't walk the double-colon chain unless
1999 this is a double-colon rule. Fix suggested by Boris Kolpackov
2000 <boris@kolpackov.net>.
2002 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2003 * readme.vms: New section describing OpenVMS support and issues.
2004 * default.c (default_variables): Add support for IA64.
2005 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2006 without some privilege aborts make with the error
2007 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2008 pressing Ctrl+Y and the input device is no terminal. The change
2009 catches this error and just continues.
2011 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2013 2004-04-25 Paul D. Smith <psmith@gnu.org>
2015 * commands.c (set_file_variables): Set $< properly in the face of
2016 order-only prerequisites.
2017 Patch from Boris Kolpackov <boris@kolpackov.net>
2019 2004-04-21 Bob Byrnes <byrnes@curl.com>
2021 * main.c (main): Notice failures to remake makefiles.
2023 2004-03-28 Paul D. Smith <psmith@gnu.org>
2025 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2027 * job.c: No default shell for RISC OS.
2028 (load_too_high): Hard-code the return to 1.
2029 (construct_command_argv_internal): No sh_chars or sh_cmds.
2030 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2032 2004-03-20 Paul D. Smith <psmith@gnu.org>
2034 * variable.c (do_variable_definition): Don't append from the
2035 global set if a previous non-appending target-specific variable
2036 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2039 * expand.c (reference_variable): Don't give up on variables with
2040 no value that have the target-specific append flag set: they might
2041 have a value after all. Reported by Oliver Schmidt
2042 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2043 <nikulin@dx1cmd.inp.nsk.su>.
2045 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2046 refer to absolute pathnames in directories that don't exist: some
2047 portion of the makefile could create those directories before we
2048 match the pattern. Fixes bugs #775 and #108.
2050 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2052 * main.c (main): Free makefile_mtimes if we have any.
2053 * README.W32.template: Update documentation for the current status
2054 of the MS-Windows port.
2055 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2056 environment variable is sometimes already defined which causes the
2058 * main.c (debug_signal_handler): Only define this function if
2059 SIGUSR1 is available.
2061 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2063 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2064 * README.OS2.template: Documentation updates.
2065 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2066 link line for safety.
2067 * maintMakefile (build.sh.in): Remove an extraneous ")".
2068 * job.c (child_execute_job): Close saved FDs.
2069 * job.c (exec_command) [OS/2]: exec_command(): If the command
2070 can't be exec'ed and if the shell is not Unix-sh, then try again
2071 with argv = { "cmd", "/c", ... }. Normally, this code is never
2072 reached for the cmd shell unless the command really doesn't exist.
2073 (construct_command_argv_internal) [OS/2]: The code for cmd
2074 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2075 The CMD builtin commands are case insensitive so use strcasecmp().
2077 2004-03-19 Paul D. Smith <psmith@gnu.org>
2079 * read.c (do_define): Re-order line counter increment so the count
2080 is accurate (we were losing one line per define). Reported by
2081 Dave Yost <Dave@Yost.com>.
2083 2004-03-06 Paul D. Smith <psmith@gnu.org>
2085 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2087 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2088 * misc.c (message,error,fatal): Ditto.
2089 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2090 * config.h.W32.template: Ditto.
2091 * config.h-vms.template: Ditto.
2092 * config.ami.template: Ditto.
2094 2004-03-04 Paul D. Smith <psmith@gnu.org>
2096 * README.template: Add a note about broken /bin/sh on SunOS
2097 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2099 * misc.c (message, error, fatal): Don't use "..." if we're using
2100 varargs. ansi2knr should handle this but it doesn't work: it
2101 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2102 done. On many systems (SunOS for example) va_dcl is a #define.
2103 So, force the use of the non-"..." version on pre-ANSI compilers.
2105 * maintMakefile (sign-dist): Create some rules to help automate
2106 the new GNU ftp upload method.
2108 2004-02-24 Paul D. Smith <psmith@gnu.org>
2110 * config.h.W32.template: Add HAVE_STDARG_H
2111 * config.h-vms.template: Ditto.
2112 * config.ami.template: Ditto.
2114 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2116 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2117 * build_w32.bat: Remove extra "+".
2119 2004-02-23 Paul D. Smith <psmith@gnu.org>
2121 * make.h: Create an UNUSED macro to mark unused parameters.
2122 * (many): Clean up warnings by applying UNUSED, fixing
2123 signed/unsigned incompatibilities, etc.
2125 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2127 * filedef.h: Name the command_state enumeration.
2128 * file.c (set_command_state): Use the enumeration in the function
2131 * configure.in: Explicitly set SET_MAKE to empty, to disable
2132 MAKE=make even when no make already exists. Fix bug #3823.
2134 2004-02-22 Paul D. Smith <psmith@gnu.org>
2136 * maintMakefile: Perl script to clean up all non-CVS files. Use
2137 it on all the subdirectories for the cvs-clean target.
2139 * main.c (decode_switches): Require non-empty strings for all our
2140 string command-line options. Fixes Debian bug # 164165.
2142 * configure.in: Check for stdarg.h and varargs.h.
2143 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2144 for printing messages.
2145 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2150 A number of patches for OS/2 support from Andreas Buening
2151 <andreas.buening@nexgo.de>:
2153 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2154 disable the SIGCHLD handler.
2155 (reap_children) [OS/2]: Remove special handling of job_rfd.
2156 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2157 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2158 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2159 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2160 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2163 2004-02-21 Paul D. Smith <psmith@gnu.org>
2165 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2166 <mail@kristov.de> reports that if process_begin() fails we don't
2167 handle the error condition correctly in all cases.
2168 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2169 to have a newline on the message.
2171 * job.c (construct_command_argv_internal): Add "test" to UNIX
2172 sh_cmds[]. Fixes Savannah bug # 7606.
2174 2004-02-04 Paul D. Smith <psmith@gnu.org>
2176 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2177 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2178 Hartmut Becker <Hartmut.Becker@hp.com>.
2180 2004-01-21 Paul D. Smith <psmith@gnu.org>
2182 * job.c (load_too_high): Implement an algorithm to control the
2183 "thundering herd" problem when using -l to control job creation
2184 via the load average. The system only recomputes the load once a
2185 second but we can start many jobs in a second. To solve this we
2186 keep track of the number of jobs started in the last second and
2187 apply a weight to try to guess what a correct load would be.
2188 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2189 Also fixes bug #4693.
2190 (reap_children): Decrease the job count for this second.
2191 (start_job_command): Increase the job count for this second.
2193 * read.c (conditional_line): Expand the text after ifn?def before
2194 checking to see if it's a single word. Fixes bug #7257.
2196 2004-01-09 Paul D. Smith <psmith@gnu.org>
2198 * file.c (print_file): Recurse to print all targets in
2199 double-colon rules. Fixes bug #4518, reported (with patch) by
2200 Andrew Chatham <chatham@google.com>.
2202 2004-01-07 Paul D. Smith <psmith@gnu.org>
2204 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2205 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2206 AC_FUNC_SETVBUF_REVERSED.
2208 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2209 (MAKE Variable): Fix Savannah bug #4898.
2211 * job.c (construct_command_argv_internal): Add "!" to the list of
2212 shell escape chars. POSIX sh allows it to appear before a
2213 command, to negate the exit code. Fixes bug #6404.
2215 * implicit.c (pattern_search): When matching an implicit rule,
2216 remember which dependencies have the ignore_mtime flag set.
2217 Original fix provided in Savannah patch #2349, by Benoit
2218 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2220 2003-11-22 Paul D. Smith <psmith@gnu.org>
2222 * README.W32.template (Outputs): Clarification on -j with
2223 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2226 2003-11-02 Paul D. Smith <psmith@gnu.org>
2228 * function.c (func_if): Strip all the trailing whitespace from the
2229 condition, then don't expand it. Fixed bug # 5798.
2231 * expand.c (recursively_expand_for_file): If we're expanding a
2232 variable with no file context, then use the variable's context.
2235 2003-10-21 Paul D. Smith <psmith@gnu.org>
2237 * main.c (log_working_directory): Add newlines to printf()s.
2239 * README.cvs: Add a note to ignore warnings during autoreconf.
2241 * maintMakefile (po_repo): Set a new URL for PO file updates.
2242 (get-config/config.guess get-config/config.sub): Get these files
2243 from the Savannah config project instead of ftp.gnu.org.
2245 2003-10-05 Paul Eggert <eggert@twinsun.com>
2247 * main.c (main): Avoid potential subscript error if environ has
2250 2003-08-22 Paul D. Smith <psmith@gnu.org>
2252 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2253 systems which don't yet implement the C89 standard :-/.
2255 2003-07-18 Paul D. Smith <psmith@gnu.org>
2257 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2258 [WINDOWS32]: Initialize hash.
2260 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2262 * dir.c (read_dirstream): Provide a workaround for broken versions of
2263 the MinGW dirent structure.
2265 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2267 * w32/include/dirent.h: Add __MINGW32__ filter.
2269 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2271 * make.h: Add global declaration of *make_host.
2272 * main.c (print_usage): Remove local declaration of *make_host.
2273 (print_version): Display "This program built for ..." after Copyright
2276 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2278 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2279 execution of "makeinfo --html make.texi".
2281 2003-04-30 Paul D. Smith <psmith@gnu.org>
2283 * build.template: Make some changes to maybe allow this script to
2284 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2286 * README.OS2.template: New file for OS/2 support. Original
2287 contributed by Andreas Buening.
2288 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2291 2003-04-19 Paul D. Smith <psmith@gnu.org>
2293 Fix bug #1405: allow a target to match multiple pattern-specific
2296 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2297 variable.c, where they've always belonged.
2298 * rule.h: Move the prototypes and struct pattern_var as well.
2299 * variable.c (initialize_file_variables): Invoke
2300 lookup_pattern_var() in a loop, until no more matches are found.
2301 If a match is found, create a new variable set for the target's
2302 pattern variables. Then merge the contents of each matching
2303 pattern variable set into the target's pattern variable set.
2304 (lookup_pattern_var): Change this function to be usable
2305 in a loop. It takes a starting position: if NULL, start at the
2306 beginning; if non-NULL, start with the pattern variable after that
2307 position, and return the next matching pattern.
2308 (create_pattern_var): Create a unique instance of
2309 pattern-specific variables for every definition in the makefile.
2310 Don't combine the same pattern together. This allows us to
2311 process the variable handling properly even when the same pattern
2312 is used multiple times.
2313 (parse_variable_definition): New function: break out the parsing
2314 of a variable definition line from try_variable_definition.
2315 (try_variable_definition): Call parse_variable_definition to
2317 (print_variable_data_base): Print out pattern-specific variables.
2318 * variable.h (struct variable): Remember when a variable is
2319 conditional. Also remember its flavor.
2320 (struct pattern_var): Instead of keeping a variable set, we just
2321 keep a single variable for each pattern.
2322 * read.c (record_target_var): Each pattern variable contains only a
2323 single variable, not a set, so create it properly.
2324 * doc/make.texi (Pattern-specific): Document the new behavior.
2326 2003-04-17 Paul D. Smith <psmith@gnu.org>
2328 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2329 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2330 file/directory naming rules for VMS so I can't tell whether this
2333 2003-04-09 Paul D. Smith <psmith@gnu.org>
2335 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2336 DOS-style pathnames: backslash separators and drive specifiers.
2338 2003-03-28 Paul D. Smith <psmith@gnu.org>
2340 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2341 the intermediate flag on all targets. Fixes bug #2515.
2343 2003-03-24 Paul D. Smith <psmith@gnu.org>
2345 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2346 Upgrade to autoconf 2.57 and automake 1.7.3.
2348 * job.c: More OS/2 changes from Andreas Buening.
2350 * file.c (print_file): Fix variable initialization.
2353 * remake.c (notice_finished_file):
2355 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2356 some calls (like readdir()) return NULL in valid situations
2357 without resetting errno. Fixes bug #2846.
2359 2003-02-25 Paul D. Smith <psmith@gnu.org>
2361 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2363 * job.c (_is_unixy_shell) [OS/2]: New function.
2364 Set default shell to /bin/sh.
2365 (reap_children): Close the job_rfd pipe here since we don't use a
2367 (set_child_handler_action_flags): define this to empty on OS/2.
2368 (start_job_command): Close the jobserver pipe and use
2369 child_execute_job() instead of fork/exec.
2370 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2371 rather than exec'ing, then reconfigure stdin/stdout.
2372 (exec_command): Rewrite to use spawn instead of exec. Return the
2375 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2376 in DOS. Handle the TEMP environment variable as in DOS. Don't
2377 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2378 use -j in DOS mode. Use child_execute_job() instead of
2381 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2384 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2385 prototypes that return values.
2387 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2389 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2390 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2392 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2395 2003-02-24 Paul D. Smith <psmith@gnu.org>
2397 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2398 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2399 (child_execute_job) [VMS]: Handle error status properly.
2400 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2402 * function.c (func_shell): Use EINTRLOOP() while reading from the
2403 subshell pipe (Fixes bug #2502).
2404 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2406 * main.c (main): Ditto.
2408 2003-01-30 Paul D. Smith <psmith@gnu.org>
2410 * read.c (eval): eval() was not fully reentrant, because the
2411 collapsed buffer was static. Change it to be an automatic
2412 variable so that eval() can be invoked recursively.
2414 (eval): Apply patch # 1022: fix memory reference error on long
2415 target-specific variable lines.
2416 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2418 * function.c (check_numeric): Combine the is_numeric() function
2419 into this function, since it's only called from one place.
2420 Constify this function. Have it print the incorrect string in the
2421 error message. Fixes bug #2407.
2422 (strip_whitespace): Constify.
2423 (func_if): Constify.
2424 * expand.c (expand_argument): Constify.
2426 2003-01-29 Paul D. Smith <psmith@gnu.org>
2428 Fix bug # 2169, also reported by other people on various systems.
2430 * make.h: Some systems, such as Solaris and PTX, do not fully
2431 implement POSIX-compliant SA_RESTART functionality; important
2432 system calls like stat() and readdir() can still fail with EINTR
2433 even if SA_RESTART has been set on the signal handler. So,
2434 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2435 EINTR for system calls which return -1 or 0 (NULL), respectively,
2437 Also, remove the old atomic_stat()/atomic_readdir() and
2438 HAVE_BROKEN_RESTART handling.
2440 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2442 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2443 * remake.c (touch_file): Ditto.
2445 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2446 * read.c (construct_include_path): Ditto.
2447 * remake.c (name_mtime): Ditto.
2448 * vpath.c (selective_vpath_search): Ditto.
2449 * dir.c (find_directory): Ditto.
2450 (local_stat): Ditto.
2451 (find_directory): Use ENULLLOOP() to wrap opendir().
2452 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2454 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2455 atomic_readdir() handling.
2457 2003-01-22 Paul D. Smith <psmith@gnu.org>
2459 * function.c (func_call): Fix Bug #1744. If we're inside a
2460 recursive invocation of $(call ...), mask any of the outer
2461 invocation's arguments that aren't used by this one, so that this
2462 invocation doesn't "inherit" them accidentally.
2464 2002-12-05 Paul D. Smith <psmith@gnu.org>
2466 * function.c (subst_expand): Valery Khamenia reported a
2467 pathological performance hit when doing substitutions on very
2468 large values with lots of words: turns out we were invoking
2469 strlen() a ridiculous number of times. Instead of having each
2470 call to sindex() call strlen() again, keep track of how much of
2471 the text we've seen and pass the length to sindex().
2473 2002-11-19 Paul D. Smith <psmith@gnu.org>
2475 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2478 2002-11-16 Paul D. Smith <psmith@gnu.org>
2480 * NMakefile.template (OBJS): Add hash.c object file.
2481 * SMakefile.template (srcs): Ditto.
2482 * Makefile.ami (objs): Ditto.
2483 * build_w32.bat: Ditto.
2485 * Makefile.DOS.template: Remove extra dependencies.
2487 2002-10-25 Paul D. Smith <psmith@gnu.org>
2489 * expand.c (install_variable_buffer): New function. Install a new
2490 variable_buffer context and return the previous one.
2491 (restore_variable_buffer): New function. Free the current
2492 variable_buffer context and put a previously saved one back.
2493 * variable.h: Prototypes for {install,restore}_variable_buffer.
2494 * function.c (func_eval): Push a new variable_buffer context
2495 before we eval, then restore the old one when we're done.
2498 * read.c (install_conditionals): New function. Install a new
2499 conditional context and return the previous one.
2500 (restore_conditionals): New function. Free the current
2501 conditional context and put a previously saved one back.
2502 (eval): Use the {install,restore}_conditionals for "include"
2504 (eval_buffer): Use {install,restore}_conditionals to preserve the
2505 present conditional state before we evaluate the buffer.
2508 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2510 (Recursion): Add a variable index entry for CURDIR.
2512 * README.cvs: Update to appropriate versions.
2513 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2514 don't need to copy loadavg.c: automake is smart enough to create
2515 it for me. Still have a bug in automake related to ansi2knr tho.
2517 2002-10-14 Paul D. Smith <psmith@gnu.org>
2519 * remake.c (notice_finished_file): Only touch targets if they have
2520 at least one command (as per POSIX). Resolve Bug #1418.
2522 * *.c: Convert to using ANSI C-style function definitions.
2523 * Makefile.am: Enable the ansi2knr feature of automake.
2524 * configure.in: ditto.
2526 2002-10-13 Paul D. Smith <psmith@gnu.org>
2528 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2529 for automatic variable values like $^, etc. In the case of very
2530 large lists of prerequisites this causes problems. Instead reuse
2531 a static buffer (resizeable) for each variable.
2533 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2534 target-specific variable definitions. Check for it and set an
2536 (record_target_var): Set the export field to v_export if the
2537 "exported" flag is set.
2538 * doc/make.texi (Target-specific): Document the ability to use
2541 * doc/make.texi: Change the name of the section on automatic
2542 variables from "Automatic" to "Automatic Variables". Added text
2543 clarifying the scope of automatic variables.
2545 2002-10-04 Paul D. Smith <psmith@gnu.org>
2547 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2549 (record_files): Ditto.
2551 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2552 the search for the '=' to only within the enclosing parens.
2554 2002-10-03 Paul D. Smith <psmith@gnu.org>
2556 Version 3.80 released.
2558 * dir.c: Change hash functions to use K&R function definition style.
2559 * function.c: Ditto.
2561 * variable.c: Ditto.
2563 Update to automake 1.7.
2565 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2566 (pdf): Remove this target as automake now provides one.
2568 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2570 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2572 * makefile.com: Updates for GNU make 3.80.
2573 * makefile.vms: Ditto.
2575 2002-09-23 Paul D. Smith <psmith@gnu.org>
2577 * read.c (enum make_word_type): Remove w_comment.
2578 (get_next_mword): Don't treat comment characters as special; where
2579 this function is used we will never see a comment (it's stripped
2580 before we get here) and treating comments specially means that
2581 targets like "foo\#bar" aren't handled properly.
2583 2002-09-18 Paul D. Smith <psmith@gnu.org>
2585 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2587 * read.c (eval): Expansion of arguments to export/unexport was
2588 ignoring all arguments after the first one. Change the algorithm
2589 to expand the whole line once, then parse the results.
2591 2002-09-17 Paul D. Smith <psmith@gnu.org>
2593 Fix Bug #940 (plus another bug I found while looking at this):
2595 * read.c (record_target_var): enter_file() will add a new entry if
2596 it's a double-colon target: we don't want to do that in this
2597 situation. Invoke lookup_file() and only enter_file() if it does
2598 not already exist. If the file we get back is a double-colon then
2599 add this variable to the "root" double-colon target.
2601 * variable.c (initialize_file_variables): If this file is a
2602 double-colon target but is not the "root" target, then initialize
2603 the root and make the root's variable list the parent of our
2606 2002-09-13 Paul D. Smith <psmith@gnu.org>
2608 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2610 * hash.c (round_up_2): Get rid of a warning.
2612 2002-09-12 Paul D. Smith <psmith@gnu.org>
2614 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2615 so it doesn't complain about getloadavg.c.
2617 * commands.c (set_file_variables): Make sure we always alloca() at
2618 least 1 character for the value of $? (for '\0').
2620 2002-09-11 Paul D. Smith <psmith@gnu.org>
2622 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2623 macro to use RESULT instead of the incorrect _RESULT_.
2625 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2626 and atomic_readdir(). We need to #include dirent.h to get this to
2628 * misc.c (atomic_readdir): Fix typos.
2630 2002-09-10 Paul D. Smith <psmith@gnu.org>
2632 * read.c (eval): Expand variable lists given to export and
2633 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2634 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2636 * doc/make.texi (Variables/Recursion): Document this.
2637 (Conditional Syntax): And here.
2639 2002-09-09 Paul D. Smith <psmith@gnu.org>
2641 * configure.in: Check for memmove().
2643 2002-09-07 Paul D. Smith <psmith@gnu.org>
2645 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2646 Michael Sterrett <msterret@coat.com> reports that while it has
2647 SA_RESTART, it does not work properly.
2649 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2650 that invokes stat() and loops to do it again if it returns EINTR.
2651 (atomic_readdir): Ditto, with readdir().
2653 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2654 and readdir() to atomic_stat() and atomic_readdir().
2656 2002-09-04 Paul D. Smith <psmith@gnu.org>
2658 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2659 reports that GNU make sometimes doesn't recognize that targets can
2660 be made, when directories can be created as prerequisites. He
2661 reports that changing the order of predicates in the DEP->changed
2662 flag test so that lookup_file() is always performed, solves this
2665 2002-08-08 Paul D. Smith <psmith@gnu.org>
2667 * configure.in: Require a newer version of gettext.
2669 * misc.c (perror_with_name): Translate the format string (for
2670 right-to-left language support).
2671 (pfatal_with_name): Ditto.
2673 * main.c: Create a static array of strings to store the usage
2674 text. This is done to facilitate translations.

2676 (switches): Remove values for obsolete fields.
2677 (print_usage): Print each element of the usage array.
2679 * hash.c: Change function definitions to be K&R style.
2681 2002-08-02 Paul D. Smith <psmith@gnu.org>
2683 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2684 this one because it's too hard to get right. We'll look at it for
2686 * main.c (main): Don't create the .TARGETS variable.
2687 * variable.c (handle_special_var): Don't handle .TARGETS.
2689 2002-08-01 Paul D. Smith <psmith@gnu.org>

2693 if they don't appear to be out of date.
2694 (always_make_flag): New flag.
2695 * make.h: Extern always_make_flag.
2696 * remake.c (update_file_1): Check always_make_flag; if it's set we
2697 will always rebuild any target we can, even if none of its
2698 prerequisites are newer.
2701 * doc/make.texi (Shell Function): Make it clear that make
2702 variables marked as "export" are not passed to instances of the
2705 Add new introspection variable .VARIABLES and .TARGETS.
2707 * variable.c (handle_special_var): New function. If the variable
2708 reference passed in is "special" (.VARIABLES or .TARGETS),
2709 calculate the new value if necessary. .VARIABLES is handled here:
2710 walk through the hash of defined variables and construct a value
2711 which is a list of the names. .TARGETS is handled by
2712 build_target_list().
2713 (lookup_variable): Invoke handle_special_var().
2714 * file.c (build_target_list): Walk through the hask of known files
2715 and construct a list of the names of all the ones marked as
2717 * main.c (main): Initialize them to empty (and as simple variables).
2718 * doc/make.texi (Special Variables): Document them.
2719 * NEWS: Mention them.
2721 * variable.h (struct variable): Add a new flag "exportable" which
2722 is true if the variable name is valid for export.
2723 * variable.c (define_variable_in_set): Set "exportable" when a new
2724 variable is defined.
2725 (target_environment): Use the "exportable" flag instead of
2726 re-checking the name here... an efficiency improvement.
2728 2002-07-31 Paul D. Smith <psmith@gnu.org>
2730 * config.h-vms.template: Updates to build on VMS. Thanks to
2731 Brian_Benning@aksteel.com for helping verify the build.
2732 * makefile.com: Build the new hash.c file.
2733 * hash.h: Use strcpmi(), not stricmp(), in the
2734 HAVE_CASE_INSENSITIVE_FS case.
2736 2002-07-30 Paul D. Smith <psmith@gnu.org>
2738 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2739 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2740 Reported by <Brian_Benning@aksteel.com>.
2742 2002-07-10 Paul D. Smith <psmith@gnu.org>
2744 * variable.c (pop_variable_scope): Remove variable made unused by
2745 new hash infrastructure.
2746 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2747 comparisons as well as name comparisons.
2748 * variable.h: Add a prototype for new hash_init_function_table().
2749 * file.c (lookup_file): Remove variables made unused by new hash
2751 * dir.c (directory_contents_hash_2): Missing return of hash value.
2752 (dir_contents_file_exists_p): Remove variables made unused by new
2753 hash infrastructure.
2756 Installed Greg McGary's integration of the hash functions from the
2757 GNU id-utils package:
2759 2002-07-10 Greg McGary <greg@mcgary.org>
2761 * scripts/functions/filter-out: Add literals to to the
2762 pattern space in order to add complexity, and trigger
2763 use of an internal hash table. Fix documentation strings.
2764 * scripts/targets/INTERMEDIATE: Reverse order of files
2765 passed to expected `rm' command.
2767 2002-07-10 Greg McGary <greg@mcgary.org>

2840 than a string constant, avoiding zillions of calls to strchr.
2841 Tighten inner search loops to test only for desired delimiters.

2859 2002-07-10 Paul D. Smith <psmith@gnu.org>
2861 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2862 prerequisite list. A real SysV make will expand the entire
2863 prerequisites list _twice_: we don't do that as it's a big
2864 backward-compatibility problem. We only replace those specific
2867 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2868 references left in the list of prerequisites. Check for .POSIX as
2869 we record targets, so we can disable non-POSIX behavior while
2870 reading makefiles as well as running them.
2871 (eval): Check the prerequisite list to see if we have anything
2872 that looks like a SysV prerequisite variable reference.
2874 2002-07-09 Paul D. Smith <psmith@gnu.org>
2876 * doc/make.texi (Prerequisite Types): Add a new section describing
2877 order-only prerequisites.
2879 * read.c (uniquize_deps): If we have the same file as both a
2880 normal and order-only prereq, get rid of the order-only prereq,
2881 since the normal one supersedes it.
2883 2002-07-08 Paul D. Smith <psmith@gnu.org>
2885 * AUTHORS: Added Greg McGary to the AUTHORS file.
2886 * NEWS: Blurbed order-only prerequisites.
2887 * file.c (print_file): Show order-only deps properly when printing
2890 * maintMakefile: Add "update" targets for wget'ing the latest
2891 versions of various external files. Taken from Makefile.maint in
2894 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2895 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2897 2002-07-07 Paul D. Smith <psmith@gnu.org>
2899 * po/*.po: Remove. We'll use wget to retrieve them at release
2902 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2903 rather than a shell you get an exception. Make sure we look up
2904 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2906 * remake.c (notice_finished_file): Fix handling of -t flag.
2907 Patch provided by Henning Makholm <henning@makholm.net>.
2909 * implicit.c (pattern_search): Some systems apparently run short
2910 of stack space, and using alloca() in this function caused an
2911 overrun. I modified it to use xmalloc() on the two variables
2912 which seemed like they might get large. Fixes Bug #476.
2914 * main.c (print_version): Update copyright notice to conform with
2916 (print_usage): Update help output.
2918 * function.c (func_eval): Create a new make function, $(eval
2919 ...). Expand the arguments, put them into a buffer, then invoke
2920 eval_buffer() on the resulting string.
2921 (func_quote): Create a new function, $(quote VARNAME). Inserts
2922 the value of the variable VARNAME without expanding it any
2925 * read.c (struct ebuffer): Change the linebuffer structure to an
2926 "eval buffer", which can be either a file or a buffer.
2927 (eval_makefile): Move the code in the old read_makefile() which
2928 located a makefile into here: create a struct ebuffer with that
2929 information. Have it invoke the new function eval() with that
2931 (eval_buffer): Create a new function that creates a struct ebuffer
2932 that holds a string buffer instead of a file. Have it invoke
2933 eval() with that ebuffer.
2934 (eval): New function that contains the guts of the old
2935 read_makefile() function: this function parses makefiles. Obtains
2936 data to parse from the provided ebuffer. Some modifications to
2937 make the flow of the function cleaner and clearer. Still could
2938 use some work here...
2939 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2940 contents of the define/endef variable from the ebuffer.
2941 (readstring): Read the next line from a string-style ebuffer.
2942 (readline): Read the next line from an ebuffer. If it's a string
2943 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2946 * dep.h (eval_buffer): Prototype eval_buffer();
2948 * variable.c (do_variable_definition): Make sure that all
2949 non-target-specific variables are registered in the global set.
2950 If we're invoked from an $(eval ...) we might be inside a $(call
2951 ...) or other function which has pushed a variable scope; we still
2952 want to define our variables from evaluated makefile code in the
2955 2002-07-03 Greg McGary <greg@mcgary.org>
2957 * dep.h (struct dep) [ignore_mtime]: New member.
2958 [changed]: convert to a bitfield.
2959 * implicit.c (pattern_search): Zero ignore_mtime.
2960 * main.c (main, handle_non_switch_argument): Likewise.
2961 * rule.c (convert_suffix_rule): Likewise.
2962 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2963 (read_makefile): Parse '|' in prerequisite list.
2964 (uniquize_deps): Consider ignore_mtime when comparing deps.
2965 * remake.c (update_file_1, check_dep): Don't force remake for
2966 dependencies that have d->ignore_mtime.
2967 * commands.c (FILE_LIST_SEPARATOR): New constant.
2968 (set_file_variables): Don't include a
2969 prerequisite in $+, $^ or $? if d->ignore_mtime.
2972 2002-06-18 Paul D. Smith <psmith@gnu.org>
2974 * make.texinfo: Updates for next revision. New date/rev/etc.
2975 Recreate all Info menus. Change license on the manual to the GNU
2976 Free Documentation License. A number of typos.
2977 (Variables Simplify): Don't use "-" before it's defined.
2978 (Automatic Prerequisites): Rewrite the target example to work
2979 properly if the compile fails. Remove incorrect comments about
2980 how "set -e" behaves.
2981 (Text Functions): Move the "word", "wordlist", "words", and
2982 "firstword" functions here, from "File Name Functions".
2983 * make-stds.texi: Update from latest GNU version.
2984 * fdl.texi: (created) Import the latest GNU version.
2986 2002-06-06 Paul D. Smith <psmith@gnu.org>
2988 * variable.c (do_variable_definition): New function: extract the
2989 part of try_variable_definition() that actually sets the value
2990 into a separate function.
2991 (try_variable_definition): Call do_variable_definition() after
2992 parsing the variable definition string.
2993 (define_variable_in_set): Make the name argument const.
2995 * variable.h (enum variable_flavor): Make public.
2996 (do_variable_definition): Create prototype.
2998 * read.c (read_all_makefiles): Create a new built-in variable,
3000 (read_makefile): Add each makefile read in to this variable value.
3002 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3004 * Makefile.DOS.template: Tweak according to changes in the
3005 distribution. Add back the dependencies of *.o files.
3007 * configh.dos.template: Synchronize with config.h.in.
3009 2002-05-09 Paul D. Smith <psmith@gnu.org>
3011 * file.c (file_timestamp_now): Use K&R function declaration.
3013 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3014 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3015 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3016 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3017 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3018 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3019 nlist.n_name is a pointer rather than an array.
3021 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3022 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3023 * configure.in: Use it instead of the old version.
3025 * main.c (main): Prefer setvbuf() to setlinebuf().
3027 2002-05-08 Paul D. Smith <psmith@gnu.org>
3029 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3030 (loadavg_LDADD): Ditto.
3032 2002-04-29 Paul D. Smith <psmith@gnu.org>
3034 * expand.c (recursively_expand_for_file): Rename
3035 recursively_expand() to recursively_expand_for_file() and provide
3036 an extra argument, struct file. If the argument is provided, set
3037 the variable scope to that of the file before expanding.
3038 * variable.h (recursively_expand): Make this a macro that invokes
3039 recursively_expand_for_file() with a NULL file pointer.
3040 * variable.c (target_environment): Call the renamed function and
3041 provide the current file context.
3042 Fixes Debian bug #144306.
3044 2002-04-28 Paul D. Smith <psmith@gnu.org>
3046 Allow $(call ...) user-defined variables to be self-referencing
3047 without throwing an error. Allows implementation of transitive
3048 closures, among other possibly useful things.
3049 Requested by: Philip Guenther <guenther@sendmail.com>
3051 * variable.h (struct variable): Add a new field: exp_count, and
3052 new macros to hold its size and maximum value.
3053 (warn_undefined): Make this a macro.
3054 * variable.c (define_variable_in_set): Initialize it.
3055 * expand.c (recursively_expand): If we detect recursive expansion
3056 of a variable, check the exp_count field. If it's greater than 0
3057 allow the recursion and decrement the count.
3058 (warn_undefined): Remove this (now a macro in variable.h).
3059 * function.c (func_call): Before we expand the user-defined
3060 function, modify its exp_count field to contain the maximum
3061 number of recursive calls we'll allow. After the call, reset it
3064 2002-04-21 Paul D. Smith <psmith@gnu.org>
3066 Modified to use latest autoconf (2.53), automake (1.6.1), and
3067 gettext (0.11.1). We're using gettext's new "external" support,
3068 to avoid including libintl source with GNU make.
3070 * README.cvs: New file. Explain how to build GNU make from CVS.
3072 * configure.in: Modify checking for the system glob library.
3073 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3074 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3075 etc. will manage it correctly). Set an automake conditional
3076 USE_LOCAL_GLOB to decide whether to compile the glob library.
3078 * getloadavg.c (main): Include make.h in the "TEST" program to
3081 * Makefile.am: Remove special rules for loadavg. Replace them
3082 with Automake capabilities for building extra programs.
3084 * signame.c: This file does nothing if the system provide
3085 strsignal(). If not, it implements strsignal(). If the system
3086 doesn't define sys_siglist, then we make our own; otherwise we use
3088 * signame.h: Removed.
3090 * main.c (main): No need to invoke signame_init(). Update copyright.
3092 * ABOUT-NLS: Removed.
3093 * gettext.c: Removed.
3094 * gettext.h: Get a simplified copy from the gettext package.
3096 * i18n/*.po: Moved to po/.
3099 * config/*: Created. Contains package configuration helper files.
3100 * config.guess, config.sub: Moved to config directory.
3102 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3103 Rework to use new-style autoconf features. Use the "external"
3104 mode for gettext. Make the build.sh config file conditional on
3105 whether build.sh.in exists, to avoid autoconf errors.
3106 * acinclude.m4: Removed almost all macros as being obsolete.
3107 Rewrote remaining macros to use AC_DEFINE.
3108 * acconfig.h: Removed.
3110 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3111 conditional to handle customs support. Remove special handling
3114 2002-04-20 Paul D. Smith <psmith@gnu.org>
3116 * function.c (func_call): Don't mark the argument variables $1,
3117 etc. as recursive. They've already been fully expanded so
3118 there's no need to do it again, and doing so strips escaped $'s.
3119 Reported by Sebastian Glita <glseba@yahoo.com>.
3121 * remake.c (notice_finished_file): Walk through double-colon
3122 entries via the prev field, not the next field!
3123 Reported by Greg McGary <greg@mcgary.org>.
3125 * main.c (main): If the user specifies -q and asks for a specific
3126 target which is a makefile, we got an assert. In that case it
3127 turns out we should continue normally instead.
3129 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3131 * i18n/he.po: Installed a new translation.

3143 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3144 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3146 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3148 (main): Get rid of any avoidable limit on stack size.

3166 * i18n/ko.po: Installed a new translation.
3168 2001-05-06 Paul D. Smith <psmith@gnu.org>
3170 Modify the EINTR handling.
3172 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3173 the way in which we manage the file descriptor/signal handler race
3174 trap to be more efficient.
3176 2001-05-06 Paul Eggert <eggert@twinsun.com>
3178 Restart almost all system calls that are interrupted, instead
3179 of worrying about EINTR. The lone exception is the read() for
3182 * configure.in (HAVE_SA_RESTART): New macro.
3183 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3184 * main.c (main): Use SA_RESTART instead of the old,
3185 nonstandard SA_INTERRUPT.
3187 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3188 * main.c (bsd_signal): New function or macro,
3189 if the implementation doesn't supply it.
3190 (The bsd_signal function will be in POSIX 1003.1-200x.)
3191 (HANDLESIG): Remove.
3192 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3194 * make.h (EINTR_SET): Remove.
3195 (SA_RESTART): New macro.
3197 * arscan.c (ar_member_touch): Don't worry about EINTR.
3198 * function.c (func_shell): Likewise.
3199 * job.c (reap_children, free_child, new_job): Likewise.
3200 * main.c (main): Likewise.
3201 * remake.c (touch_file, name_mtime): Likewise.
3203 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3204 if fstat failed with errno!=EINTR, the error was ignored.
3206 * job.c (set_child_handler_action_flags): New function.
3207 (new_job): Use it to temporarily clear the SIGCHLD action flags
3208 while reading the token.
3210 2001-05-02 Paul D. Smith <psmith@gnu.org>
3212 * job.c (start_job_command): Don't add define/endef per-line flags
3213 to the top-level flags setting.
3215 2001-04-03 Paul D. Smith <psmith@gnu.org>
3217 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3218 bit on error, so check for odd return values, not non-0 return
3220 (VMS_get_member_info): Calculate the timezone differences correctly.
3221 Reported by John Fowler <jfowler@nyx.net>.
3224 2001-03-14 Paul D. Smith <psmith@gnu.org>
3226 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3227 value before invoking define_variable().
3228 Reported by John Fowler <jfowler@nyx.net>.
3230 2001-02-07 Paul D. Smith <psmith@gnu.org>
3232 * read.c (record_target_var): If we reset the variable due to a
3233 command-line variable setting overriding it, turn off the "append"
3236 2001-01-17 Paul D. Smith <psmith@gnu.org>
3238 * variable.c (lookup_variable) [VMS]: When getting values from the
3239 environment, allocate enough space for the _value_ plus escapes,
3240 not enough space for the name plus escapes :-/.
3241 Reported by John Fowler <jfowler@nyx.net>.
3243 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3244 warnings that make generates, so it doesn't look like an error.
3245 Reported by Karl Berry <karl@gnu.org>.
3248 Fix for PR/2020: Rework appended target-specific variables. I'm
3249 fairly confident this algorithm is finally correct.
3251 * expand.c (allocated_variable_append): Rewrite. Instead of
3252 expanding each appended variable then adding all the expanded
3253 strings together, we append all the unexpanded values going up
3254 through the variable set contexts, then expand the final result.
3255 This behaves just like non-target-specific appended variable
3256 values, while the old way didn't in various corner cases.
3257 (variable_append): New function: recursively append the unexpanded
3258 value of a variable, walking from the outermost variable scope to
3260 * variable.c (lookup_variable): Remove the code that looked up the
3261 variable set list if the found variable was "append". We don't
3263 (lookup_variable_in_set): Make this non-static so we can use it
3265 (try_variable_definition): Use lookup_variable_in_set() rather
3266 than faking out current_variable_set_list by hand (cleanup).
3267 * variable.h: Add a prototype for the now non-static
3268 lookup_variable_in_set().
3270 2000-11-17 Paul D. Smith <psmith@gnu.org>
3272 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3273 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3274 before throwing a fit.
3276 2000-11-17 Paul D. Smith <psmith@gnu.org>
3278 * read.c (readline): CRLF calculations had a hole, if you hit the
3279 buffer grow scenario just right. Reworked the algorithm to avoid
3280 the need for len or lastlen at all. Problem description with
3281 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3283 2000-10-24 Paul D. Smith <psmith@gnu.org>
3285 * gettext.c (SWAP): Declare this with the prototype, otherwise
3286 some systems don't work (non-32-bit? Reported for Cray T3E).
3287 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3289 2000-10-05 Paul D. Smith <psmith@gnu.org>
3291 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3292 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3294 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3296 2000-09-22 Paul D. Smith <psmith@gnu.org>
3298 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3299 parts of the real gettext.h here, and we expect to really include
3300 the real gettext.h later. If we keep this #define, it's ignored.
3302 2000-09-21 Paul D. Smith <psmith@gnu.org>
3304 * main.c (log_working_directory): Rework the text to use complete
3305 sentences, to make life simpler for the translators.
3307 2000-08-29 Paul D. Smith <psmith@gnu.org>
3309 * file.c (remove_intermediates): Print a debug message before we
3310 remove intermediate files, so the user (if she uses -d) knows
3313 2000-08-21 Paul D. Smith <psmith@gnu.org>
3315 * variable.c (try_variable_definition): Change how we handle
3316 target-specific append variable defns: instead of just setting the
3317 value, expand it as an append _but_ only within the current
3318 target's context. Otherwise we lose all but the last value if the
3319 variable is appended more than once within the current target
3320 context. Fixes PR/1831.
3322 2000-08-16 Paul D. Smith <psmith@gnu.org>
3324 * function.c (func_shell): Nul-terminate the buffer before
3325 printing an exec error message (just in case it's not!).
3326 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3328 2000-07-25 Paul D. Smith <psmith@gnu.org>
3330 * job.c (construct_command_argv_internal): Add "~" to the list of
3331 sh_chars[] which disallow optimizing out the shell call.
3333 2000-07-23 Paul Eggert <eggert@twinsun.com>
3335 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3336 supersedes --disable-nsec-timestamps.
3337 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3338 * README: Remove --disable-nsec-timestamps.
3340 * filedef.h (struct file.low_resolution_time): New member.
3341 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3342 * remake.c (update_file_1):
3343 Avoid spurious rebuilds due to low resolution time stamps,
3344 generalizing the earlier code that applied only to archive members.
3345 (f_mtime): Archive members always have low resolution time stamps.
3347 * configure.in: Remove --disable-nsec-timestamps, as this has
3348 been superseded by .LOW_RESOLUTION_TIME.
3350 2000-07-23 Paul Eggert <eggert@twinsun.com>
3352 * configure.in (enable_nsec_timestamps): Renamed from
3353 make_cv_nsec_timestamps, since enable/disable options
3354 shouldn't be cached.
3356 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3357 and Paul Eggert <eggert@twinsun.com>
3359 * file.c (file_timestamp_now):
3360 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3361 so that clock_gettime is not linked unless needed.
3363 * filedef.h (FILE_TIMESTAMP_HI_RES):
3364 Remove definition; "configure" now does this.
3366 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3367 to before high resolution file timestamp check,
3368 since that check now uses uintmax_t.
3369 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3370 high resolution file timestamps.
3371 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3372 so that we don't link in clock_gettime unnecessarily.
3374 2000-07-17 Paul D. Smith <psmith@gnu.org>
3376 * i18n/ja.po: New version of the translation file.
3378 2000-07-07 Paul D. Smith <psmith@gnu.org>
3380 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3381 the offset calculation.
3382 (name_mtime): Replace EINTR test with EINTR_SET macro.
3384 2000-07-07 Paul Eggert <eggert@twinsun.com>
3388 * remake.c (update_file_1):
3389 Avoid spurious rebuilds of archive members due to their
3390 timestamp resolution being only one second.
3391 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3392 the clock's resolution being lower than file timestamps'.
3393 When warning about future timestamps, report only the discrepancy,
3394 not the absolute value of the timestamp and the current time.
3396 * file.c (file_timestamp_now): New arg RESOLUTION.
3397 * filedef.h (file_timestamp_now): Likewise.
3398 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3400 2000-07-05 Paul D. Smith <psmith@gnu.org>
3402 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3403 to listp. Fixes PR/1793.
3405 2000-06-26 Paul Eggert <eggert@twinsun.com>
3407 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3409 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3411 * remake.c (f_mtime): Remove unused var memtime.
3413 2000-06-25 Martin Buchholz <martin@xemacs.org>
3415 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3416 Ran spell-check on make.texinfo.
3418 2000-06-23 Paul D. Smith <psmith@gnu.org>
3420 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3421 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3422 * make.h: Define these macros.
3424 * Version 3.79.1 released.
3426 * configure.in: Add a new option, --disable-nsec-timestamps, to
3427 avoid using sub-second timestamps on systems that support it. It
3428 can lead to problems, e.g. if your makefile relies on "cp -p".
3429 * README.template: Document the issue with "cp -p".
3431 * config.guess, config.sub: Updated.
