3 * expand.c (expand_argument): If the argument is large enough use
4 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
6 * variable.c (do_variable_definition): Avoid using alloca() to
7 hold values, which can be large. Fixes Savannah bug #23960.
9 * job.c (new_job): Use memmove() instead of strcpy() since both
10 pointers are in the same memory block. Fixes Savannah bug #27148.
11 Patch by Petr Machata.
13 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
15 * job.c (construct_command_argv_internal): Add "ulimit" and
16 "unset" to the sh_cmds for Unixy shells.
18 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
20 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
21 that set make_cv_sys_gnu_glob, so they are also correctly set
22 when the cache has been populated before.
24 2009-07-04 Eli Zaretskii <eliz@gnu.org>
26 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
27 exist, as realpath(3) does where it's supported.
29 2006-07-04 Eli Zaretskii <eliz@gnu.org>
31 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
32 (abspath): Support systems that define HAVE_DOS_PATHS (have
33 drive letters in their file names). Use IS_PATHSEP instead of a
34 literal '/' comparison. Fixes Savannah bug #26886.
36 2009-06-14 Paul Smith <psmith@gnu.org>
38 * remake.c (update_file_1): Remember the original file we marked
39 as updating, so we can clear that flag again. If we find a target
40 via vpath, FILE might change.
41 (check_dep): Ditto. Fixes Savannah bug #13529.
42 Patch by Reid Madsen <reid.madsen@tek.com>.
44 2009-06-13 Paul Smith <psmith@gnu.org>
46 * doc/make.texi (MAKEFILES Variable): Be explicit that files
47 included by MAKEFILES cannot give default goals.
48 * read.c (eval): If set_default is not set, pass the no-default-goal
49 value when we read included makefiles. Fixes Savannah bug #13401.
51 * ar.c (ar_name): Ensure that targets with empty parens aren't
52 considered archive member references: archive members must have a
53 non-empty "member" string. Fixes Savannah bug #18435.
55 * function.c (string_glob): Rely on multi_glob() to determine
56 whether files exist or not. Remove call to file_exists_p() which
57 is not always correct. Fixes Savannah bug #21231.
58 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
59 then only files that really exist will be returned.
60 * dep.h: Add new argument to multi_glob().
61 * rule.c (install_pattern_rule): Ditto.
62 * read.c (eval): Ditto.
63 * main.c (main): Ditto.
64 * implicit.c (pattern_search): Ditto.
65 * file.c (parse_prereqs): Ditto.
66 * default.c (set_default_suffixes): Ditto.
68 2009-06-09 Paul Smith <psmith@gnu.org>
70 * commands.c (set_file_variables): If always_make_flag is set,
71 always add the prereq to $?. Fixes Savannah bug #17825.
73 * remake.c (update_file_1): When rebuilding deps of FILE, also try
74 to rebuild the deps of all the also_make targets for that file.
75 Fixes Savannah bug #19108.
77 * implicit.c (pattern_search): Undo test for is_target, added by
78 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
79 Rule Search Algorithm". Fixes Savannah bug #17752.
81 * main.c (clean_jobserver): Clear the jobserver_fds options and
82 set job_slots to the default when we clean up.
83 (define_makeflags): Return the new MAKEFLAGS value.
84 (main): Reset MAKEFLAGS in the environment when we re-exec.
85 Fixes Savannah bug #18124.
87 2009-06-08 Paul Smith <psmith@gnu.org>
89 * read.c (eval): Collapse continuations post-semicolon on target-
90 specific variables. Fixes Savannah bug #17521.
92 2009-06-07 Paul Smith <psmith@gnu.org>
94 * job.c (reap_children): For older systems without waitpid() (are
95 there any of these left?) run wait(2) inside EINTRLOOP to handle
96 EINTR errors. Fixes Savannah bug #16401.
98 * (various): Debug message cleanup. Fixes Savannah bug #16469.
100 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
102 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
103 not the end, to catch second expansion $(eval ...) defining new
104 target/prereq relationships during snap_deps.
105 Fixes Savannah bug #24622.
107 * read.c (record_files): The second-expansion "f->updating" hack
108 was not completely correct: if assumed that the target with
109 commands always had prerequisites; if one didn't then the ordering
110 was messed up. Fixed for now to use f->updating to decide whether
111 to preserve the last element in the deps list... but this whole
112 area of constructing and reversing the deps list is too confusing
113 and needs to be reworked. Fixes Savannah bug #21198.
115 2009-06-06 Paul Smith <psmith@gnu.org>
117 * hash.c (hash_insert): Remove useless test for NULL.
118 Fixes Savannah bug #21823.
120 * make.h: Move SET_STACK_SIZE determination to make.h.
121 * main.c (main): New global variable, STACK_LIMIT, holds the
122 original stack limit when make was started.
123 * job.c (start_job_command): Reset the stack limit, if we changed it.
124 Fixes Savannah bug #22010.
126 * remake.c (check_dep): Only set the target's state to not-started
127 if it's not already running. Found this while testing -j10 builds
128 of glibc: various targets were being rebuilt multiple times.
129 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
132 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
133 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
136 2009-06-04 Paul Smith <psmith@gnu.org>
138 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
140 * maintMakefile: Modify access of config and gnulib Savannah
141 modules to use GIT instead of CVS.
143 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
144 Fixes Savannah bug #24655.
146 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
147 this can happen during some invocations of $(eval ...) for example.
148 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
150 2009-06-02 Paul Smith <psmith@gnu.org>
152 * configure.in: Check for fileno()
153 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
154 for the makefile file so invocations of $(shell ...) don't inherit it.
155 Fixes Savannah bug #24277.
157 2009-06-01 Paul Smith <psmith@gnu.org>
159 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
160 expansion was handled incorrectly. Rework the default goal
161 handling to save the variable only. Remove default_goal_file and
163 * read.c (eval): Check default_goal_var, not default_goal_name.
164 * read.c (record_target_var): Don't check default_goal_file here.
166 2009-05-31 Paul Smith <psmith@gnu.org>
168 * main.c (main): Expand the .DEFAULT_GOAL variable before using
169 it, and if the multi_glob() returns nothing (say it expanded to
170 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
172 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
173 $(and ..) to the reference. Fixes Savannah bug #25694.
175 * make.1: Be clear that some recipes will be executed even with -n.
176 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
178 * doc/make.texi (Override Directive): Make more clear how
179 overrides and appends interact.
180 Elucidates part of Savannah bug #26207.
182 * read.c (record_target_var): Don't reset the origin on
183 target-specific variables; try_variable_definition() will handle
184 this correctly. Fixes Savannah bug #26207.
186 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
187 Fixes Savannah bug #25712.
189 * implicit.c (pattern_search): Keep a pointer to the beginning of
190 the filename and save that instead of the constructed pointer.
191 Fixes Savannah bug #26593.
192 Patch by Mark Seaborn <mrs@mythic-beasts.com>
194 2009-05-30 Paul Smith <psmith@gnu.org>
196 * doc/make.texi (Multi-Line): Add a description of the new abilities
197 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
198 "command sequence" vs. "recipe" syntax.
199 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
200 after a define, to create variables with those flavors.
202 2009-05-25 Paul Smith <psmith@gnu.org>
204 Reworked the parser for variable assignments to allow multiple
205 modifiers, and in any order. Also allows variable and
206 prerequisites to be modifier names ('export', 'private', etc.)
208 * NEWS: Add notes about user-visible changes.
210 * read.c (struct vmodifiers): Remember what modifiers were seen.
211 (parse_var_assignment): New function to parse variable assignments.
212 (eval): Call the new function. Handle variable assignments earlier.
214 * variable.c (parse_variable_definition): Only parse; don't create var.
215 (assign_variable_definition): Call parse, then create the var.
217 2009-05-24 Paul Smith <psmith@gnu.org>
219 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
220 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
222 2009-03-14 Eli Zaretskii <eliz@gnu.org>
224 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
225 Fixes Savannah bug #25412.
227 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
228 prototype for xmalloc.
229 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
230 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
231 Loop over an array of extensions, instead of duplicating the same
232 code inline. Use SearchPath followed by CreateFile, instead of
233 the obsolete OpenFile. Fixes Savannah bug #17277.
234 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
235 to `find_file'. Fixes Savannah bug #25662.
237 2009-03-07 Eli Zaretskii <eliz@gnu.org>
239 * function.c (func_shell): Don't close pipedes[1] if it is -1.
240 Fixes Savannah bug #20495.
242 2009-02-28 Ralf Wildenhues <address@hidden>
244 * doc/make.texi (Instead of Execution): Document interaction of
245 -t with phony targets.
247 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
249 Introduce a new keyword "private" which applies to target-specific
250 variables and prevents their values from being inherited.
252 * variable.h (struct variable): Add private_var flag to each variable.
253 Add a flag to specify which list entry switches to the parent target.
254 * variable.c (define_variable_in_set): Initialize private_var flag.

258 * read.c (eval): Recognize the private keyword.
259 (record_target_var): Set private_var.
260 * doc/make.texi (Suppressing Inheritance): Add documentation.
262 2008-10-26 Paul Smith <psmith@gnu.org>
264 * configure.in: Check for strndup().
265 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
267 * make.h: Rename savestring to xstrndup.
268 * commands.c (chop_commands): Ditto.

270 * read.c (eval, record_files): Ditto.
271 * variable.c (define_variable_in_set): Ditto.
273 2008-09-30 Eli Zaretskii <eliz@gnu.org>
275 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
278 * w32/subproc/build.bat (GCCBuild): Likewise.
280 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
282 * job.c (construct_command_argv_internal): Avoid extra backslash
283 in batch-mode Unixy shells. Under DB_JOBS, display the contents
286 2008-05-31 Eli Zaretskii <eliz@gnu.org>
288 * README.W32.template: Remove obsolete text about non-support for
289 -jN without Unixy shell. Remove obsolete text about not supplying
290 Visual Studio project files (we do supply them). Modify text to
291 prefer GCC builds to MSC builds.
293 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
295 * doc/make.texi (Empty Targets): Fix typo.
297 2008-03-27 Paul Smith <psmith@gnu.org>
299 Fix Savannah bug #22379:
300 * ar.c (ar_glob_match): Zero the allocated structure.
301 * read.c (parse_file_seq): Ditto.
303 2008-03-08 Brian Dessent <brian@dessent.net>
305 * maintMakefile: Update Translation Project location.
307 2008-01-26 Eli Zaretskii <eliz@gnu.org>
309 * variable.c (target_environment): Don't use shell_var if its
310 `value' field is NULL.
312 2007-12-22 Eli Zaretskii <eliz@gnu.org>
314 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
316 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
317 (TEXINFOS): Value changed to `doc/make.texi'.
318 (.SUFFIXES): Use .texi instead of .texinfo.
319 (make.info, make.dvi): Depend on doc/make.texi.
320 (.texi.info): New target, instead of ".texinfo.info". Change -I
321 switch to $(MAKEINFO) to look in doc/. Use --no-split.
322 (.texi): New target, instead of ".texinfo". Change -I switch to
323 $(MAKEINFO) to look in doc/. Use --no-split.
324 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
325 switch to $(MAKEINFO) to look in doc/.
326 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
327 "*.i[0-9][0-9]" (due to --no-split above).
328 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
329 (html, make_1.html): New targets.
330 (.PHONY): Add "html".
331 (.SUFFIXES): Add .html.
333 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
335 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
336 HAVE_DECL_SYS_SIGLIST.
338 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
339 build does not use child_execute_job.
341 * variable.c (define_automatic_variables) [__MSDOS__]: Always
342 export the SHELL environment variable to the child.
344 2007-12-22 Eli Zaretskii <eliz@gnu.org>
346 * config.h.W32: Include sys/types.h.
347 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

350 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
353 2007-11-04 Paul Smith <psmith@gnu.org>
355 * doc/make.texi: Convert references to "commands", "command
356 lines", and "command script" to "recipe".
358 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
361 2007-10-27 Bruno Haible <bruno@clisp.org>
363 * remake.c (f_mtime): Print time difference values between 100 and
364 ULONG_MAX in fixed-point notation rather than in exponention notation.
366 2007-10-12 Eli Zaretskii <eliz@gnu.org>
368 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
369 a more complex value than a simple shell: if it's not a default
370 shell now then expand it and see if is a default shell then.
372 2007-10-10 Eli Zaretskii <eliz@gnu.org>
374 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
375 pathnames, with const strings.
376 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
377 from the template (used for building from CVS, not a dist).
379 2007-10-10 Paul Smith <psmith@gnu.org>
381 * make.h: Add a prototype for w32_kill() (change suggested by
382 Yongwei Wu <wuyongwei@gmail.com>).
384 2007-09-21 Eli Zaretskii <eliz@gnu.org>
386 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
389 2007-09-12 Paul Smith <psmith@gnu.org>
391 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
392 Provided by Diego Biurrun <diego@biurrun.de>
393 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
394 Provided by Diego Biurrun <diego@biurrun.de>
396 2007-09-11 Paul Smith <psmith@gnu.org>
398 * doc/make.texi (Special Variables): Moved this into the "How to
399 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
400 (MAKEFILE_LIST) No longer a section; this was added into the
401 "Special Variables" section.
402 (Rule Introduction): Reference .RECIPEPREFIX.
403 (Simple Makefile): Ditto.
404 (Rule Syntax): Ditto.
405 (Command Syntax): Ditto.
406 (Error Messages): Ditto.
408 2007-09-10 Paul Smith <psmith@gnu.org>
410 * commands.c (print_commands): Don't print an extra line in the
411 command scripts. Prefix the command scripts with cmd_prefix, not \t.
413 * read.c (construct_include_path): Add the full string to the cache; we
414 were chopping the last char.
416 * NEWS: Announce the .RECIPEPREFIX special variable.
417 * variable.c (lookup_special_var): Rename from handle_special_var().
418 (lookup_variable): Call the new name.
419 (set_special_var): New function: handle setting of special variables.
420 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
421 (do_variable_definition): Call it.
422 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
423 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
424 * main.c (main): Create the .RECIPEPREFIX special variable.
425 * read.c (eval): Remove the cmd_prefix characters from the command
426 scripts here, so they're not stored in the commands array at all,
427 rather than waiting and stripping them out during command construction.
428 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
430 2007-08-15 Paul Smith <psmith@gnu.org>
432 * doc/make.texi (GNU Free Documentation License): The fdl.texi
433 file has had the section info removed, so add some to make.texi
434 before we include it.
436 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
438 * remake.c (check_dep): Reset the target state for intermediate
439 files. They might have been considered before but not updated
440 then (order-only for example) but they will be this time.
441 Fixes Savannah bug #'s 3330 and 15919.
443 2007-07-21 Eli Zaretskii <eliz@gnu.org>
445 Fix Savannah bug #20549:
446 * function.c (func_shell): Call construct_command_argv with zero
448 * job.c (construct_command_argv_internal): New argument FLAGS; all
450 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
452 * job.h (construct_command_argv_internal): Update prototype.
454 2007-07-13 Paul Smith <psmith@gnu.org>
456 * file.c (expand_deps): Use variable_buffer as the start of the
457 buffer, not the original pointer (in case it was reallocated).
458 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
459 Fixes Savannah bug #20452.
461 2007-07-04 Paul Smith <psmith@gnu.org>
463 * (ALL FILES): Update to GPLv3.
464 * (ALL FILES): Update copyright for 2007.
466 * main.c (print_version): Move the host type info to the second line.
468 2007-06-29 Thiemo Seufer <ths@mips.com>
470 * maintMakefile: Update Translation Project location.
472 2007-06-13 Paul Smith <psmith@gnu.org>
474 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
475 "Expansion of a deferred"
476 Fixes Savannah bug #20018.
478 * expand.c (variable_expand_for_file): Preserve the value of
479 reading_file rather than setting it to 0 at the end.
480 Fixes Savannah bug #20033.
482 2007-05-11 Paul Smith <psmith@gnu.org>
484 * job.c (new_job): Add debug info to specify where make found the
485 command script it is running to build a target.
486 Fixes Savannah bug #18617.
488 * default.c (default_suffixes,default_suffix_rules,default_variables):
489 Add support for Objective C. Fixes Savannah bug #16389.
490 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
492 * function.c (func_lastword): Initialize p.
494 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
495 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
496 Dave Korn <dave.korn@artimi.com>
498 2007-05-08 Paul Smith <psmith@gnu.org>
500 Fix Savannah bug #19656:
502 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
504 * make.h: Change all case-insensitive string compares to use
505 strcasecmp() (from POSIX). If we don't have that but do have one
506 of the others, define strcasecmp to be one of those instead. If
507 we don't have any, declare a prototype for our own version.
509 * misc.c (strcasecmp): Use this if we can't find any native
510 case-insensitive string comparison function.
511 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
512 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
514 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
515 strcasecmp() instead of stricmp().
516 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
517 instead of strcmpi().
518 * acinclude.m4: Remove the strcasecmp() check from here.
520 2007-03-21 Paul Smith <psmith@gnu.org>
522 * configure.in: Don't turn on case-insensitive file system support
523 if --disable-... is given. Fixes Savannah bug #19348.
525 2007-03-19 Paul Smith <psmith@gnu.org>
527 * ALL: Use the strcache for all file name strings, or other
528 strings which we will never free. The goal is to save memory by
529 avoiding duplicate copies of strings. However, at the moment this
530 doesn't save much memory in most situations: due to secondary
531 expansion we actually save prerequisite lists twice (once before
532 the secondary expansion, and then again after it's been parsed
533 into individual file names in the dep list). We will resolve this
534 in a future change, by doing the parsing up-front for targets
535 where secondary expansion is not set.
537 Moving things into the strcache also allows us to use const
538 pointers in many more places.
540 2007-01-03 Paul Smith <psmith@gnu.org>
542 * make.h (ENULLLOOP): Reset errno after each failed invocation of
543 the function, not just the first. Fixes Savannah bug #18680.
545 2006-11-18 Paul Smith <psmith@gnu.org>
547 * strcache.c (strcache_add_len): Don't allocate a new buffer
548 unless the string is not already nil-terminated. Technically this
549 is a violation of the standard, since we may be passed an array
550 that is not long enough to test one past. However, in make this
551 is never true since we only use nil-terminated strings or
554 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.

650 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
651 that don't have extended grep.
652 (cvsclean): Use $(PERL) instead of perl.
654 2006-04-09 Paul D. Smith <psmith@gnu.org>

720 Declare and define sh_chars_sh[].
722 2006-03-23 Paul D. Smith <psmith@gnu.org>
724 * configure.in: Look for build.sh.in in $srcdir so it will be
725 built for remote configurations as well.
727 * Makefile.am: Make sure to clean up build.sh during distclean.
728 Fixes Savannah bug #16166.
730 * misc.c (log_access): Takes a const char *.
731 * function.c (fold_newlines): Takes an unsigned int *.
732 Both fixes for Savannah bug #16170.

746 make sure I don't forget any).
748 * main.c (clean_jobserver): Move jobserver cleanup code into a new
750 (die): Cleanup code was removed from here; call the new function.
751 (main): If we are re-execing, clean up the jobserver first so we
752 don't leak file descriptors.
753 Reported by Craig Fithian <craig.fithian@citigroup.com>
755 2006-03-17 Paul D. Smith <psmith@gnu.org>

766 (free_dep_chain): Use free_dep.
767 * read.c (record_files): Store stem in the dependency line.
768 * file.c (expand_deps): Use stem stored in the dependency line. Use

781 (allocated_variable_append): Don't expand the final result.
782 Fixes Savannah bug #15913.
784 2006-03-09 Paul Smith <psmith@gnu.org>
786 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
787 listed non-existent files as changed. Turns out there's a bug in
788 the Linux kernel builds which means that this change causes
789 everything to rebuild every time. We will re-introduce this fix
790 in the next release, to give them time to fix their build system.
791 Fixes Savannah bug #16002.
792 Introduces Savannah bug #16051.
794 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
795 we *don't* find UNIX "/".

807 to be null; don't core in that case.
809 2006-02-19 Paul D. Smith <psmith@gnu.org>
811 * commands.c (set_file_variables): Realloc, not malloc, the static
812 string values to avoid memory leaks.
814 * expand.c (recursively_expand_for_file): Only set reading_file to
815 an initialized value.
817 * implicit.c (pattern_search): We need to make a copy of the stem
818 if we get it from an intermediate dep, since those get freed.
820 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
822 (enter_file) [VMS]: Ditto.
823 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
825 2006-02-24 Eli Zaretskii <eliz@gnu.org>
827 * job.c (construct_command_argv_internal): Fix last change.
829 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
830 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
831 the calls to _beginthreadex.
833 * expand.c (recursively_expand_for_file): Initialize `save' to
834 prevent compiler warnings.
836 2006-02-18 Eli Zaretskii <eliz@gnu.org>
838 * job.c (construct_command_argv_internal): Don't create a temporary
839 script/batch file if we are under -n. Call _setmode to switch the
840 script file stream to text mode.
842 2006-02-17 Paul D. Smith <psmith@gnu.org>
844 * variable.c (merge_variable_set_lists): Don't try to merge the
845 global_setlist. Not only is this useless, but it can lead to
846 circularities in the linked list, if global_setlist->next in one
847 list gets set to point to another list which also ends in
849 Fixes Savannah bug #15757.
851 2006-02-15 Paul D. Smith <psmith@gnu.org>
853 Fix for Savannah bug #106.
855 * expand.c (expanding_var): Keep track of which variable we're
856 expanding. If no variable is being expanded, it's the same as
858 * make.h (expanding_var): Declare it.
859 * expand.c (recursively_expand_for_file): Set expanding_var to the
860 current variable we're expanding, unless there's no file info in
861 it (could happen if it comes from the command line or a default
862 variable). Restore it before we exit.
863 * expand.c (variable_expand_string): Use the expanding_var file
864 info instead of the reading_file info.

874 * read.c (eval): Even if the included filenames expands to the
875 empty string we still need to free the allocated buffer.
877 * implicit.c (pattern_search): If we allocated a variable set for
878 an impossible file, free it.
879 * variable.c (free_variable_set): New function.
880 * variable.h: Declare it.
882 * read.c (read_all_makefiles): Makefile names are kept in the
883 strcache, so there's never any need to alloc/free them.
886 * main.c (main): Add "archives" to the .FEATURES variable if
887 archive support is enabled.
888 * doc/make.texi (Special Variables): Document it.
890 2006-02-13 Paul D. Smith <psmith@gnu.org>
892 * implicit.c (pattern_search): Add checking for DOS pathnames to
893 the pattern rule target LASTSLASH manipulation.

898 * (ALL FILES): Updated copyright and license notices.
900 2006-02-10 Paul D. Smith <psmith@gnu.org>
902 A new internal capability: the string cache is a read-only cache
903 of strings, with a hash table interface for fast lookup. Nothing
904 in the cache will ever be freed, so there's no need for reference
905 counting, etc. This is the beginning of a full solution for
906 Savannah bug #15182, but for now we only store makefile names here.
908 * strcache.c: New file. Implement a read-only string cache.
909 * make.h: Add prototypes for new functions.
910 * main.c (initialize_global_hash_tables): Initialize the string cache.
911 (print_data_base): Print string cache stats.

917 * dir.c (dir_contents_file_exists_p): Don't opendir if the
918 directory time stamp didn't change, except on FAT filesystems.
919 Suggested by J. David Bryan <jdbryan@acm.org>.
921 2006-02-09 Paul D. Smith <psmith@gnu.org>
923 * function.c (func_or): Implement a short-circuiting OR function.
924 (func_and): Implement a short-circuiting AND function.
925 (function_table_init): Update the table with the new functions.
926 * doc/make.texi (Conditional Functions): Changed the "if" section
927 to one on general conditional functions. Added documentation for
928 $(and ...) and $(or ...) functions.
929 * NEWS: Note new $(and ...) and $(or ...) functions.

938 2006-02-06 Paul D. Smith <psmith@gnu.org>
940 * vpath.c (selective_vpath_search): If the file we find has a
941 timestamp from -o or -W, use that instead of the real time.
942 * remake.c (f_mtime): If the mtime is a special token from -o or
943 -W, don't overwrite it with the real mtime.

957 2006-02-05 Paul D. Smith <psmith@gnu.org>
959 * file.c (enter_file): Keep track of the last double_colon entry,

961 Fixes Savannah bug #15533.
962 * filedef.h (struct file): Add a new LAST pointer.
964 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
965 the comparison. For 64-bits systems the result of the subtraction
966 might not fit into an int. Use comparison instead.
967 Fixes Savannah bug #15534.
969 * doc/make.texi: Update the chapter on writing commands to reflect

990 2006-01-21 Eli Zaretskii <eliz@gnu.org>
992 * remake.c (update_goal_chain): Set g->changed instead of
993 incrementing it, as it is only 8-bit wide, and could overflow if
994 many commands got started in update_file.
996 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
998 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

1009 the load were too high.
1010 (start_job_command): Fix a typo in error message when process_easy
1013 2006-01-14 Eli Zaretskii <eliz@gnu.org>

1016 the shell is not sh.exe.
1018 * job.c (create_batch_file): Renamed from create_batch_filename;
1019 all callers changed. Don't close the temporary file; return its
1020 file descriptor instead. New arg FD allows to return the file
1022 (construct_command_argv_internal): Use _fdopen instead of fopen to
1023 open the batch file.
1025 2006-01-04 Paul D. Smith <psmith@gnu.org>
1027 * readme.vms: Updates for case-insensitive VMS file systems from

1054 * doc/make.texi (Execution): Add a footnote about changes in
1055 handling of backslash-newline sequences. Mention the differences
1056 on MS-DOS and MS-Windows.
1058 * NEWS: More details about building the MinGW port and a pointer
1059 to README.W32. Fix the section name that describes the new
1060 backward-incompatible processing of backslash-newline sequences.
1061 The special processing of SHELL set to "cmd" is only relevant to
1062 MS-Windows, not MS-DOS.
1064 2005-12-17 Eli Zaretskii <eliz@gnu.org>

1067 to DWORD, to avoid compiler warnings.

1084 with v_default instead of leaving it "initialized" by whatever
1085 garbage happened to be on the heap.
1087 2005-12-12 Paul D. Smith <psmith@gnu.org>
1089 * make.1: Fix some display errors and document all existing options.
1090 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1092 2005-12-11 Paul D. Smith <psmith@gnu.org>
1094 * implicit.c (pattern_search): If 2nd expansion is not set for
1095 this implicit rule, replace the pattern with the stem directly,
1096 and don't re-expand the variable list. Along with the other
1097 .SECONDEXPANSION changes below, fixes bug #13781.
1099 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1101 * implicit.c (pattern_search): Mark other files that this rule
1102 builds as targets so that they are not treated as intermediates
1103 by the pattern rule search algorithm. Fixes bug #13022.
1105 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1107 * remake.c (notice_finished_file): Propagate the change of
1108 modification time to all the double-colon entries only if
1109 it is the last one to be updated. Fixes bug #14334.
1111 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1113 * function.c (func_flavor): Implement the flavor function which
1114 returns the flavor of a variable.
1115 * doc/make.texi (Functions for Transforming Text): Document it.
1116 * NEWS: Add it to the list of new functions.
1118 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1120 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1122 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1123 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1125 2005-10-26 Paul Smith <psmith@gnu.org>
1127 * read.c (record_files): Don't set deps flags if there are no deps.
1128 * maintMakefile: We only need to build the templates when we are
1129 creating a distribution, so don't do it for "all".
1131 2005-10-24 Paul D. Smith <psmith@gnu.org>
1133 Make secondary expansion optional: its enabled by declaring the
1134 special target .SECONDEXPANSION.
1136 * NEWS: Update information on second expansion capabilities.
1137 * doc/make.texi (Secondary Expansion): Document the
1138 .SECONDEXPANSION special target and its behavior.
1139 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1140 prerequisite list was found in a static pattern rule.
1141 (free_dep_chain): Declare a prototype.
1142 * file.c (parse_prereqs): New function: break out some complexity
1144 (expand_deps): If we aren't doing second expansion, replace % with
1145 the stem for static pattern rules. Call the new function.
1146 * filedef.h (parse_prereqs): Declare a prototype.
1147 * implicit.c (pattern_search): Initialize the new staticpattern
1149 * main.c (second_expansion): Declare a global variable to remember
1150 if the special target has been seen. Initialize the new
1151 staticpattern field for prerequisites.
1152 * make.h: Extern for second_expansion.
1153 * misc.c (free_dep_chain): New function: frees a struct dep list.
1154 * read.c (read_all_makefiles): Initialize the staticpattern field.
1155 (eval_makefile): Ditto.
1156 (record_files): Check for the .SECONDEXPANSION target and set
1157 second_expansion global if it's found.
1158 Use the new free_dep_chain() instead of doing it by hand.
1159 Set the staticpattern field for prereqs of static pattern targets.
1161 2005-10-16 Paul D. Smith <psmith@gnu.org>
1163 * main.c (main): Set CURDIR to be a file variable instead of a
1164 default, so that values of CURDIR inherited from the environment
1165 won't override the make value.
1167 2005-09-26 Paul D. Smith <psmith@gnu.org>
1169 * job.c (construct_command_argv_internal): If the line is empty
1170 remember to free the temporary argv strings.
1173 2005-09-16 Paul D. Smith <psmith@gnu.org>
1175 * job.c (start_job_command): The noerror flag is a boolean (single
1176 bit); set it appropriately.
1177 Reported by Mark Eichin <eichin@metacarta.com>
1179 2005-08-29 Paul D. Smith <psmith@gnu.org>
1181 * function.c (func_error): On Windows, output from $(info ...)
1182 seems to come in the wrong order. Try to force it with fflush().
1184 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1186 * read.c (record_files): Move code that sets stem for static
1187 pattern rules out of the if (!two_colon) condition so it is
1188 also executed for two-colon rules. Fixes Savannah bug #13881.
1190 2005-08-08 Paul D. Smith <psmith@gnu.org>
1192 * make.h: Don't test that __STDC__ is non-0. Some compilers
1193 (Windows for example) set it to 0 to denote "ISO C + extensions".
1196 2005-08-07 Paul D. Smith <psmith@gnu.org>
1198 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1199 conditional (slightly different version of a fix from Eli).
1201 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1202 If make is running in parallel without -k and two jobs die in a
1203 row, but not too close to each other, then make will quit without
1204 waiting for the rest of the jobs to die.
1206 * main.c (die): Don't reset err before calling reap_children() the
1207 second time: we still want it to be in the error condition.
1208 * job.c (reap_children): Use a static variable, rather than err,
1209 to control whether or not the error message should be printed.
1211 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1213 * w32/subproc/sub_proc.c: Include signal.h.
1214 (process_pipe_io, process_file_io): Pass a pointer to a local
1215 DWORD variable to GetExitCodeProcess. If the exit code is
1216 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1218 * job.c [WINDOWS32]: Include windows.h.
1219 (main_thread) [WINDOWS32]: New global variable.
1220 (reap_children) [WINDOWS32]: Get the handle for the main thread
1221 and store it in main_thread.
1223 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1224 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1225 doing anything else. When we are done, close the main thread
1226 handle and exit with status 130.
1228 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1230 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1233 * main.c (find_and_set_default_shell): If found a DOSish shell,
1234 set sh_found and the value of default_shell, and report the
1235 findings in debug mode.
1237 * job.c (construct_command_argv_internal): Check unixy_shell, not
1238 no_default_sh_exe, to decide whether to use Unixy or DOSish
1241 * README.W32: Update with info about the MinGW build.
1243 * build_w32.bat: Support MinGW.
1245 * w32/subproc/build.bat: Likewise.
1247 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1248 printing DWORD args.
1250 * function.c (windows32_openpipe): Fix format strings for printing
1253 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1255 (start_job_command): Fix format string for printing the result of
1257 (start_job_command) [WINDOWS32]: Do not define.
1258 (exec_command): Fix format string for printing HANDLE args.
1260 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1261 to avoid compiler warnings.
1262 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1263 (Note: some of these fixes were submitted independently by J. Grant)
1265 2005-07-30 J. Grant <jg@jguk.org>
1267 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1268 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1269 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1271 2005-07-15 Paul Smith <psmith@gnu.org>
1273 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1274 we don't have a POSIX shell, then revert to the old
1275 backslash-newline behavior (where they are stripped).
1278 2005-07-08 Paul D. Smith <psmith@gnu.org>
1280 * config.h.W32.template: Reorder to match the standard config.h,
1281 for easier comparisons.
1282 From J. Grant <jg@jguk.org>
1284 * maintMakefile: Remove .dep_segment before overwriting it, in
1285 case it's not writable or noclobber is set.
1286 * expand.c (variable_expand_string): Cast result of pointer
1287 arithmetic to avoid a warning.
1288 * main.c (switches): Add full-fledged final initializer.
1290 2005-07-06 Paul D. Smith <psmith@gnu.org>
1292 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1293 * signame.c (strsignal): If we found _sys_siglist[] or
1294 __sys_siglist[] use those instead of sys_siglist[].
1295 From Albert Chin <china@thewrittenword.com>
1297 2005-07-04 Paul D. Smith <psmith@gnu.org>
1299 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1300 globfree(); set up to use the GNU versions.
1301 From Martin Zinser <zinser@zinser.no-ip.info>
1303 2005-07-03 Paul D. Smith <psmith@gnu.org>
1305 From J. Grant <jg@jguk.org>:
1307 * README.W32.template: Update the Windows and tested MSVC versions.
1308 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1309 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1310 * build_w32.bat: Ditto.
1311 * w32/subproc/build.bat: Ditto.
1313 2005-06-28 Paul D. Smith <psmith@gnu.org>
1315 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1316 declaration was checked but not present.
1318 2005-06-27 Paul D. Smith <psmith@gnu.org>
1320 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1321 to unsigned long. Fixes Savannah bug #13550.
1323 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1324 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1325 Fixes Savannah bug #13551.
1327 2005-06-26 Paul D. Smith <psmith@gnu.org>
1329 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1330 it if ANSI_STRING is not set.
1332 2005-06-25 Paul D. Smith <psmith@gnu.org>
1334 * read.c (eval): If no filenames are passed to any of the
1335 "include" variants, don't print an error.
1336 * doc/make.texi (Include): Document this.
1337 Fixes Savannah bug #1761.
1339 * job.c (construct_command_argv_internal): Sanitize handling of
1340 backslash/newline pairs according to POSIX: that is, keep the
1341 backslash-newline in the command script, but remove a following
1342 TAB character, if present. In the fast path, make sure that the
1343 behavior matches what the shell would do both inside and outside
1344 of quotes. In the slow path, quote the backslash and put a
1345 literal newline in the string.
1346 Fixes Savannah bug #1332.
1347 * doc/make.texi (Execution): Document the new behavior and give
1349 * NEWS: Make a note of the new behavior.
1351 * make.h [WINDOWS32]: #include <direct.h>.
1352 Fixes Savannah bug #13478.
1354 * remake.c (name_mtime): If the stat() of a file fails and the -L
1355 option was given and the file is a symlink, take the best mtime of
1356 the symlink we can get as the mtime of the file and don't fail.
1357 Fixes Savannah bug #13280.
1359 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1360 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1361 inside a variable reference. Make this function static as it's
1363 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1364 parsing an unexpanded line looking for semicolons.
1365 Fixes Savannah bug #1454.
1366 * misc.c (remove_comments): Move this to read.c and make it static
1367 as it's only used there. Call find_char_unquote() with new arg.
1368 * make.h: Remove prototypes for find_char_unquote() and
1369 remove_comments() since they're static now.
1371 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1372 its export flag and obtain its value. When we need to re-exec,
1373 increment the value and add it into the environment.
1374 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1375 * NEWS: Mention MAKE_RESTARTS.
1376 * main.c (always_make_set): New variable. Change the -B option to
1377 set this one instead.
1378 (main): When checking makefiles, only set always_make_flag if
1379 always_make_set is set AND the restarts flag is 0. When building
1380 normal targets, set it IFF always_make_set is set.
1381 (main): Avoid infinite recursion with -W, too: only set what-if
1382 files to NEW before we check makefiles if we've never restarted
1383 before. If we have restarted, set what-if files to NEW _after_ we
1385 Fixes Savannah bug #7566:
1387 2005-06-17 Paul D. Smith <psmith@gnu.org>
1389 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1390 in the prerequisites list.
1392 2005-06-12 Paul D. Smith <psmith@gnu.org>
1394 Fix Savannah bug # 1328.
1396 * configure.in: Check for atexit().
1397 * misc.c (close_stdout): Test stdout to see if writes to it have
1398 failed. If so, be sure to exit with a non-0 error code. Based on
1399 code found in gnulib.
1400 * make.h: Prototype.
1401 * main.c (main): Install close_stdout() with atexit().
1403 2005-06-10 Paul D. Smith <psmith@gnu.org>
1405 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1407 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1408 headers; make vmsWaitForChildren() static; extern vmsify().
1409 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1410 Don't create child_execute_job() here (it's in vmsjobs.c).
1411 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1413 2005-06-09 Paul D. Smith <psmith@gnu.org>
1415 * variable.c (push_new_variable_scope): File variables point
1416 directly to the global_setlist variable. So, inserting a new
1417 scope in front of that has no effect on those variables: they
1418 don't go through current_variable_set_list. If we're pushing a
1419 scope and the current scope is global, push it "the other way" so
1420 that the new setlist is in the global_setlist variable, and
1421 next points to a new setlist with the global variable set.
1422 (pop_variable_scope): Properly undo a push with the new
1424 Fixes Savannah bug #11913.
1426 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1428 * job.c (reap_children): Don't die of the command failed but
1429 the dontcare flag is set. Fixes Savannah bug #13216.
1431 * implicit.c (pattern_search): When creating a target from
1432 an implicit rule match, lookup pattern target and set precious
1433 flag in a newly created target. Fixes Savannah bug #13218.
1435 2005-05-13 Paul D. Smith <psmith@gnu.org>
1437 Implement "if... else if... endif" syntax.
1439 * read.c (eval): Push all checks for conditional words ("ifeq",
1440 "else", etc.) down into the conditional_line() function.
1441 (conditional_line): Rework to allow "else if..." clause. New
1442 return value -2 for lines which are not conditionals. The
1443 ignoring flag can now also be 2, which means "already parsed a
1444 true branch". If that value is seen no other branch of this
1445 conditional can be considered true. In the else parsing if there
1446 is extra text after the else, invoke conditional_line()
1447 recursively to see if it's another conditional. If not, it's an
1448 error. If so, raise the conditional value to this level instead
1449 of creating a new conditional nesting level. Special check for
1450 "else" and "endif", which aren't allowed on the "else" line.
1451 * doc/make.texi (Conditional Syntax): Document the new syntax.
1453 2005-05-09 Paul D. Smith <psmith@gnu.org>
1455 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1456 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1457 recurses to the w32 directory, even on non-Windows systems. Use
1458 the method suggested in the automake manual.
1459 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1460 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1462 2005-05-07 Paul D. Smith <psmith@gnu.org>
1464 * main.c (die): If we're dying with a fatal error (not that a
1465 command has failed), write back any leftover tokens before we go.
1467 * job.c (set_child_handler_action_flags): If there are jobs
1468 waiting for the load to go down, set an alarm to go off in 1
1469 second. This allows us to wake up from a potentially long-lasting
1470 read() and start a new job if the load has gone down. Turn it off
1472 (job_noop): Dummy signal handler function.
1473 (new_job): Invoke it with the new semantics.
1475 * docs/make.texi: Document secondary expansion. Various cleanups
1478 2005-05-03 Paul D. Smith <psmith@gnu.org>
1480 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1481 the targets which are to ultimately be made are called "goals";
1482 see the GNU make manual. Also, MAKECMDGOALS, etc.
1484 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1485 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1486 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1488 2005-05-02 Paul D. Smith <psmith@gnu.org>
1490 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1491 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1492 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1493 functions to vmsjobs.c. #include it into jobs.c.
1495 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1496 jobserver tokens. I found that this happens when an exported
1497 recursive variable contains a $(shell ...) function reference: in
1498 this situation we could "forget" to write back a token.
1500 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1501 we have. It's not reliable to depend on the number of children in
1502 our linked list so keep a separate count.
1503 (new_job): Check jobserver_tokens rather than children &&
1504 waiting_jobs. Increment jobserver_tokens when we get one.
1505 (free_child): If jobserver_tokens is 0, internal error. If it's
1506 >1, write a token back to the jobserver pipe (we don't write a
1507 token for the "free" job). Decrement jobserver_tokens.
1509 * main.c: Add variable master_job_slots.
1510 (main): Set it to hold the number of jobs requested if we're the
1511 master process, when using the jobserver.
1512 (die): Sanity checks: first test jobserver_tokens to make sure
1513 this process isn't holding any tokens we didn't write back.
1514 Second, if master_job_slots is set count the tokens left in the
1515 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1517 2005-04-24 Paul D. Smith <psmith@gnu.org>
1519 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1520 with -l# can lose jobserver tokens, because waiting jobs are not
1521 consulted properly when checking for the "free" token.
1523 * job.c (free_child): Count waiting_jobs as having tokens.
1524 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1525 handle jobs waiting for the load to drop.
1527 2005-04-23 Paul D. Smith <psmith@gnu.org>
1529 * main.c (main): Be careful to not core if a variable setting in
1530 the environment doesn't contain an '='. This is illegal but can
1531 happen in broken setups.
1532 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1534 2005-04-12 Paul D. Smith <psmith@gnu.org>
1536 The second expansion feature causes significant slowdown. Timing
1537 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1538 read the makefile before the feature, to 11+s to do the same
1539 operations after the feature. Additionally, memory usage
1540 increased drastically. To fix this I added some intelligence that
1541 avoids the overhead of the second expansion unless it's required.
1543 * dep.h: Add a new boolean field, need_2nd_expansion.
1545 * read.c (eval): When creating the struct dep for the target,
1546 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1547 (record_files): If there's a "%" in a static pattern rule, it gets
1548 converted to "$*" so set need_2nd_expansion to 1.
1550 * file.c (expand_deps): Rework to be more efficient. Only perform
1551 initialize_file_variables(), set_file_variables(), and
1552 variable_expand_for_file() if the need_2nd_expansion is set.
1554 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1555 (pattern_search): Ditto.
1556 * main.c (handle_non_switch_argument): Ditto.
1558 * read.c (read_all_makefiles): Ditto.
1559 (eval_makefile): Ditto.
1561 2005-04-07 Paul D. Smith <psmith@gnu.org>
1563 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1564 * variable.c (sync_Path_environment): Ditto.
1565 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1567 * main.c (main): Define the .FEATURES variable.
1568 * NEWS: Announce .FEATURES.
1569 * doc/make.texi (Special Variables): Document .FEATURES.
1571 * remake.c (check_dep): If a file is .PHONY, update it even if
1572 it's marked intermediate. Fixes Savannah bug #12331.
1574 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1576 * file.c (expand_deps): Factor out the second expansion and
1577 prerequisite line parsing logic from snap_deps().
1579 * file.c (snap_deps): Use expand_deps(). Expand and parse
1580 prerequisites of the .SUFFIXES special target first. Fixes
1581 Savannah bug #12320.
1583 2005-03-13 Paul D. Smith <psmith@gnu.org>
1585 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1588 2005-03-11 Paul D. Smith <psmith@gnu.org>
1590 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1591 available, not undefined (from Earnie Boyd).
1593 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1595 * implicit.c (pattern_search): Mark an intermediate target as
1596 precious if it happened to be a prerequisite of some (other)
1597 target. Fixes Savannah bug #12267.
1599 2005-03-09 Paul D. Smith <psmith@gnu.org>
1601 * read.c (eval_makefile): Add alloca(0).
1602 (eval_buffer): Ditto.
1604 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1606 * main.c (main): Use o_file instead of o_default when defining
1607 the .DEFAULT_TARGET special variable.
1608 * read.c (eval): Use define_variable_global() instead of
1609 define_variable() when setting new value for the .DEFAULT_TARGET
1610 special variable. Fixes Savannah bug #12266.
1612 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1614 * imlicit.c (pattern_search): Mark files for which an implicit
1615 rule has been found as targets. Fixes Savannah bug #12202.
1617 2005-03-04 Paul D. Smith <psmith@gnu.org>
1620 * doc/make.texi (Automatic Variables): Document $|.
1622 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1624 * read.c (record_files): Instead of substituting % with
1625 actual stem value in dependency list replace it with $*.
1626 This fixes stem triple expansion bug.
1628 * implicit.c (pattern_search): Copy stem to a separate
1629 buffer and make it a properly terminated string. Assign
1630 this buffer instead of STEM (which is not terminated) to
1631 f->stem. Instead of substituting % with actual stem value
1632 in dependency list replace it with $*. This fixes stem
1633 triple expansion bug.
1635 2005-03-01 Paul D. Smith <psmith@gnu.org>
1637 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1638 on Windows, as it takes a handle not a pid. Just exit.
1639 Fix from patch #3679, provided by Alessandro Vesely.
1641 * configure.in: Update check for sys_siglist[] from autoconf manual.
1642 * signame.c (strsignal): Update to use the new autoconf macro.
1644 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1646 * read.c (record_files): Add a check for the list of prerequisites
1647 of a static pattern rule being empty. Fixes Savannah bug #12180.
1649 2005-02-28 Paul D. Smith <psmith@gnu.org>
1651 * doc/make.texi (Text Functions): Update docs to allow the end
1652 ordinal for $(wordlist ...) to be 0.
1653 * function.c (func_wordlist): Fail if the start ordinal for
1654 $(wordlist ...) is <1. Matches documentation.
1655 Resolves Savannah support request #103195.
1657 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1658 previously we were stopping when !-q, exactly the opposite. This
1659 has been wrong since version 1.34, in 1994!
1660 (update_file): If we got an error don't break out to run more
1661 double-colon rules: just return immediately.
1662 Fixes Savannah bug #7144.
1664 2005-02-27 Paul D. Smith <psmith@gnu.org>
1666 * misc.c (end_of_token): Make argument const.
1667 * make.h: Update prototype.
1669 * function.c (abspath, func_realpath, func_abspath): Use
1670 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1671 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1672 * read.c (record_files): Ditto.
1673 * variable.c (do_variable_definition): Ditto.
1675 * function.c (func_error): Create a new function $(info ...) that
1676 simply prints the message to stdout with no extras.
1677 (function_table_init): Add new function to the table.
1678 * NEWS: Add $(info ...) reference.
1679 * doc/make.texi (Make Control Functions): Document it.
1681 New feature: if the system supports symbolic links, and the user
1682 provides the -L/--check-symlink-time flag, then use the latest
1683 mtime between the symlink(s) and the target file.
1685 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1686 readlink(). If both are available, define MAKE_SYMLINKS.
1687 * main.c: New variable: check_symlink_flag.
1688 (usage): Add a line for -L/--check-symlink-times to the help string.
1689 (switches): Add -L/--check-symlink-times command line argument.
1690 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1691 print a warning and disable it again.
1692 * make.h: Declare check_symlink_flag.
1693 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1694 if the file is a symlink then check each link in the chain and
1695 choose the NEWEST mtime we find as the mtime for the file. The
1696 newest mtime might be the file itself!
1697 * NEWS: Add information about this new feature.
1698 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1700 Avoid core dumps described in Savannah bug # 12124:
1702 * file.c: New variable snapped_deps remember whether we've run
1704 (snap_deps): Set it.
1705 * filedef.h: Extern it.
1706 * read.c (record_files): Check snapped_deps; if it's set then
1707 we're trying to eval a new target/prerequisite relationship from
1708 within a command script, which we don't support. Fatal.
1710 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1712 Implementation of the .DEFAULT_TARGET special variable.
1714 * read.c (eval): If necessary, update default_target_name when
1716 * read.c (record_files): Update default_target_file if
1717 default_target_name has changed.
1718 * main.c (default_target_name): Define.
1719 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1720 default_target_name is set use default_target_file as a root
1722 * filedef.h (default_target_name): Declare.
1723 * dep.h (free_dep_chain):
1724 * misc.c (free_dep_chain): Change to operate on struct nameseq
1725 and change name to free_ns_chain.
1726 * file.c (snap_deps): Update to use free_ns_chain.
1728 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1730 Implementation of the second expansion in explicit rules,
1731 static pattern rules and implicit rules.
1733 * read.c (eval): Refrain from chopping up rule's dependencies.
1734 Store them in a struct dep as a single dependency line. Remove
1735 the code that implements SySV-style automatic variables.
1737 * read.c (record_files): Adjust the code that handles static
1738 pattern rules to expand all percents instead of only the first
1739 one. Reverse the order in which dependencies are stored so that
1740 when the second expansion reverses them again they appear in
1741 the makefile order (with some exceptions, see comments in
1742 the code). Remove the code that implements SySV-style automatic
1745 * file.c (snap_deps): Implement the second expansion and chopping
1746 of dependency lines for explicit rules.
1748 * implicit.c (struct idep): Define an auxiliary data type to hold
1749 implicit rule's dependencies after stem substitution and
1752 * implicit.c (free_idep_chain): Implement.
1754 * implicit.c (get_next_word): Implement helper function for
1755 parsing implicit rule's dependency lines into words taking
1756 into account variable expansion requests. Used in the stem
1759 * implicit.c (pattern_search): Implement the second expansion
1760 for implicit rules. Also fixes bug #12091.
1762 * commands.h (set_file_variables): Declare.
1763 * commands.c (set_file_variables): Remove static specifier.
1765 * dep.h (free_dep_chain): Declare.
1766 * misc.c (free_dep_chain): Implement.
1768 * variable.h (variable_expand_for_file): Declare.
1769 * expand.c (variable_expand_for_file): Remove static specifier.
1771 * make.h (strip_whitespace): Declare.
1772 * function.c (strip_whitespace): Remove static specifier.
1774 2005-02-26 Paul D. Smith <psmith@gnu.org>
1776 * main.c (main): Check for ferror() when reading makefiles from stdin.
1777 Apparently some shells in Windows don't close pipes properly and
1780 2005-02-24 Jonathan Grant <jg@jguk.org>
1782 * configure.in: Add MinGW configuration options, and extra w32 code
1784 * Makefile.am: Add MinGW configuration options, and extra w32 code
1786 * main.c: Determine correct program string (after last \ without .exe).
1787 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1789 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1790 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1791 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1792 environment support.
1794 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1796 * function.c (func_shell): When initializing error_prefix, check
1797 that reading file name is not null. This fixes long-standing
1798 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1800 2005-02-09 Paul D. Smith <psmith@gnu.org>
1802 * maintMakefile: Update the CVS download URL to simplify them.
1803 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1804 downloading the .texi files from Savannah now.
1806 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1808 * main.c (handle_non_switch_argument): Only add variables to
1809 command_variables if they're not already there: duplicate settings
1810 waste space and can be confusing to read.
1812 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1813 this header is never included by non-WINDOWS32 code, and it
1814 requires <config.h> to define which isn't always included first.
1816 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1817 testing MINGW32 versions.
1819 * main.c (log_working_directory): flush stdout to be sure the WD
1820 change is printed before any stderr messages show up.
1822 2005-02-01 Paul D. Smith <psmith@gnu.org>
1824 * maintMakefile (po_repo): Update the GNU translation site URL.
1826 2004-12-01 Paul D. Smith <psmith@gnu.org>
1828 * main.c (main): Change char* env_shell to struct variable shell_var.
1829 * variable.c (target_environment): Use new shell_var.
1831 2004-11-30 Paul D. Smith <psmith@gnu.org>
1833 * configure.in: The old way we avoided creating build.sh from
1834 build.sh.in before build.sh.in exists doesn't work anymore; we
1835 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1836 the help!). This also keeps automake from complaining.
1837 * Makefile.am (README): Add a dummy target so automake won't
1838 complain that this file doesn't exist when we checkout from CVS.
1839 * maintMakefile (.dep_segment): Rewrite this rule since newer
1840 versions of automake don't provide DEP_FILES.
1842 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1844 Implementation of `realpath' and `abspath' built-in functions.
1846 * configure.in: Check for realpath.
1847 * function.c (abspath): Return an absolute file name that does
1848 not contain any `.' or `..' components, nor repeated `/'.
1849 * function.c (func_abspath): For each name call abspath.
1850 * function.c (func_realpath): For each name call realpath
1851 from libc or delegate to abspath if realpath is not available.
1852 * doc/make.texi (Functions for File Names): Document new functions.
1853 * doc/make.texi (Quick Reference): Ditto.
1855 2004-11-28 Paul D. Smith <psmith@gnu.org>
1857 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1858 arguments. Fixes bug #10252.
1860 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1862 * main.c (main): Set SHELL to v_noexport by default. Remember the
1863 original environment setting of SHELL in the env_shell variable.
1864 * main.h: Export new env_shell variable.
1865 * variable.c (target_environment): If we find a v_noexport
1866 variable for SHELL, add a SHELL variable with the env_shell value.
1867 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1868 * doc/make.texi (Variables/Recursion): Ditto.
1870 2004-11-28 Paul D. Smith <psmith@gnu.org>
1872 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1873 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1874 Patch by Alessandro Vesely.
1876 2004-11-12 Paul D. Smith <psmith@gnu.org>
1878 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1879 the command line if it's inside a string.
1880 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1882 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1884 * function.c (func_lastword): New function: return last word
1885 from the list of words.
1886 * doc/make.texi: Document $(lastword ). Fix broken links in
1887 Quick Reference section.
1889 2004-10-06 Paul D. Smith <psmith@gnu.org>
1891 Apply patch from Alessandro Vesely, provided with bug # 9748.
1892 Fix use of tmpnam() to work with Borland C.
1894 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1895 construction of a temporary filename, and call new function
1896 create_batch_filename().
1897 (create_batch_filename) [WINDOWS32]: New function to create a
1900 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1902 * read.c (record_target_var): Expand simple pattern-specific
1904 * variable.c (initialize_file_variables): Do not expand simple
1905 pattern-specific variable.
1907 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1909 * remake.c (update_file_1): When rebuilding makefiles inherit
1910 dontcare flag from a target that triggered update.
1912 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1914 * variable.c (initialize_file_variables): Mark pattern-specific
1915 variable as a per-target and copy export status.
1917 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1919 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1921 * implicit.c (pattern_search): When considering an implicit rule's
1922 prerequisite check that it is actually a target rather then
1923 just an entry in the file hashtable.
1925 2004-09-21 Paul D. Smith <psmith@gnu.org>
1927 * read.c (readstring): Fix some logic errors in backslash handling.
1928 (eval): Remove some unnecessary processing in buffer handling.
1929 (record_target_var): Assert that parse_variable_definition() succeeded.
1930 Reported by: Markus Mauhart <qwe123@chello.at>.
1932 * misc.c: Removed the sindex() function. All instances of this
1933 function were trivially replaceable by the standard strstr()
1934 function, and that function will always have better (or certainly
1935 no worse) performance than the very simple-minded algorithm
1936 sindex() used. This can matter with complex makefiles.
1937 * make.h: Remove the prototype for sindex().
1938 * function.c (subst_expand): Convert sindex() call to strstr().
1939 This means we no longer need to track the TLEN value so remove that.
1940 (func_findstring): Convert sindex() to strstr().
1941 * commands.c (chop_commands): Convert sindex() calls to strstr().
1942 Suggested by: Markus Mauhart <qwe123@chello.at>.
1944 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1945 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1946 If SHELL is set to CMD.EXE then assume it's batch-mode and
1947 non-unixy. I wrote the code differently from the patch, though,
1948 to make it safer. This also resolves bug #9174.
1950 2004-09-20 Paul D. Smith <psmith@gnu.org>
1952 * expand.c (variable_expand_string): Modify to invoke
1953 patsubst_expand() instead of subst_expand(); the latter didn't
1954 handle suffix patterns correctly.
1955 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1956 was used only from variable_expand_string() and is no longer used
1958 (func_subst): Ditto, on call to subst_expand().
1959 (patsubst_expand): Require the percent pointers to point to the
1960 character after the %, not to the % itself.
1961 * read.c (record_files): New call criteria for patsubst_expand().
1962 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1963 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1965 2004-09-19 Paul D. Smith <psmith@gnu.org>
1967 * function.c (subst_expand): Fix a check in by_word: look for a
1968 previous blank if we're beyond the beginning of the string, not
1969 the beginning of the word.
1970 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1972 2004-05-16 Paul D. Smith <psmith@gnu.org>
1974 * remake.c (update_goal_chain): Change the argument specifying
1975 whether we're rebuilding makefiles to be a global variable,
1976 REBUILDING_MAKEFILES.
1977 (complain): Extract the code that complains about no rules to make
1978 a target into a separate function.
1979 (update_file_1): If we tried to rebuild a file during the makefile
1980 rebuild phase and it was dontcare, then no message was printed.
1981 If we then try to build the same file during the normal build,
1982 print a message this time.
1983 (remake_file): Don't complain about un-remake-able files when
1984 we're rebuilding makefiles.
1986 2004-05-11 Paul D. Smith <psmith@gnu.org>
1988 * job.c (construct_command_argv_internal): OS/2 patches from
1989 Andreas Buening <andreas.buening@nexgo.de>.
1991 2004-05-10 Paul D. Smith <psmith@gnu.org>
1993 * remake.c (update_file): Don't walk the double-colon chain unless
1994 this is a double-colon rule. Fix suggested by Boris Kolpackov
1995 <boris@kolpackov.net>.
1997 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1998 * readme.vms: New section describing OpenVMS support and issues.
1999 * default.c (default_variables): Add support for IA64.
2000 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2001 without some privilege aborts make with the error
2002 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2003 pressing Ctrl+Y and the input device is no terminal. The change
2004 catches this error and just continues.
2006 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2008 2004-04-25 Paul D. Smith <psmith@gnu.org>
2010 * commands.c (set_file_variables): Set $< properly in the face of
2011 order-only prerequisites.
2012 Patch from Boris Kolpackov <boris@kolpackov.net>
2014 2004-04-21 Bob Byrnes <byrnes@curl.com>
2016 * main.c (main): Notice failures to remake makefiles.
2018 2004-03-28 Paul D. Smith <psmith@gnu.org>
2020 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2022 * job.c: No default shell for RISC OS.
2023 (load_too_high): Hard-code the return to 1.
2024 (construct_command_argv_internal): No sh_chars or sh_cmds.
2025 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2027 2004-03-20 Paul D. Smith <psmith@gnu.org>
2029 * variable.c (do_variable_definition): Don't append from the
2030 global set if a previous non-appending target-specific variable
2031 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2034 * expand.c (reference_variable): Don't give up on variables with
2035 no value that have the target-specific append flag set: they might
2036 have a value after all. Reported by Oliver Schmidt
2037 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2038 <nikulin@dx1cmd.inp.nsk.su>.
2040 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2041 refer to absolute pathnames in directories that don't exist: some
2042 portion of the makefile could create those directories before we
2043 match the pattern. Fixes bugs #775 and #108.
2045 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2047 * main.c (main): Free makefile_mtimes if we have any.
2048 * README.W32.template: Update documentation for the current status
2049 of the MS-Windows port.
2050 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2051 environment variable is sometimes already defined which causes the
2053 * main.c (debug_signal_handler): Only define this function if
2054 SIGUSR1 is available.
2056 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2058 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2059 * README.OS2.template: Documentation updates.
2060 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2061 link line for safety.
2062 * maintMakefile (build.sh.in): Remove an extraneous ")".
2063 * job.c (child_execute_job): Close saved FDs.
2064 * job.c (exec_command) [OS/2]: exec_command(): If the command
2065 can't be exec'ed and if the shell is not Unix-sh, then try again
2066 with argv = { "cmd", "/c", ... }. Normally, this code is never
2067 reached for the cmd shell unless the command really doesn't exist.
2068 (construct_command_argv_internal) [OS/2]: The code for cmd
2069 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2070 The CMD builtin commands are case insensitive so use strcasecmp().
2072 2004-03-19 Paul D. Smith <psmith@gnu.org>
2074 * read.c (do_define): Re-order line counter increment so the count
2075 is accurate (we were losing one line per define). Reported by
2076 Dave Yost <Dave@Yost.com>.
2078 2004-03-06 Paul D. Smith <psmith@gnu.org>
2080 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2082 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2083 * misc.c (message,error,fatal): Ditto.
2084 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2085 * config.h.W32.template: Ditto.
2086 * config.h-vms.template: Ditto.
2087 * config.ami.template: Ditto.
2089 2004-03-04 Paul D. Smith <psmith@gnu.org>
2091 * README.template: Add a note about broken /bin/sh on SunOS
2092 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2094 * misc.c (message, error, fatal): Don't use "..." if we're using
2095 varargs. ansi2knr should handle this but it doesn't work: it
2096 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2097 done. On many systems (SunOS for example) va_dcl is a #define.
2098 So, force the use of the non-"..." version on pre-ANSI compilers.
2100 * maintMakefile (sign-dist): Create some rules to help automate
2101 the new GNU ftp upload method.
2103 2004-02-24 Paul D. Smith <psmith@gnu.org>
2105 * config.h.W32.template: Add HAVE_STDARG_H
2106 * config.h-vms.template: Ditto.
2107 * config.ami.template: Ditto.
2109 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2111 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2112 * build_w32.bat: Remove extra "+".
2114 2004-02-23 Paul D. Smith <psmith@gnu.org>
2116 * make.h: Create an UNUSED macro to mark unused parameters.
2117 * (many): Clean up warnings by applying UNUSED, fixing
2118 signed/unsigned incompatibilities, etc.
2120 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2122 * filedef.h: Name the command_state enumeration.
2123 * file.c (set_command_state): Use the enumeration in the function
2126 * configure.in: Explicitly set SET_MAKE to empty, to disable
2127 MAKE=make even when no make already exists. Fix bug #3823.
2129 2004-02-22 Paul D. Smith <psmith@gnu.org>
2131 * maintMakefile: Perl script to clean up all non-CVS files. Use
2132 it on all the subdirectories for the cvs-clean target.
2134 * main.c (decode_switches): Require non-empty strings for all our
2135 string command-line options. Fixes Debian bug # 164165.
2137 * configure.in: Check for stdarg.h and varargs.h.
2138 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2139 for printing messages.
2140 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2145 A number of patches for OS/2 support from Andreas Buening
2146 <andreas.buening@nexgo.de>:
2148 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2149 disable the SIGCHLD handler.
2150 (reap_children) [OS/2]: Remove special handling of job_rfd.
2151 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2152 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2153 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2154 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2155 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2158 2004-02-21 Paul D. Smith <psmith@gnu.org>
2160 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2161 <mail@kristov.de> reports that if process_begin() fails we don't
2162 handle the error condition correctly in all cases.
2163 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2164 to have a newline on the message.
2166 * job.c (construct_command_argv_internal): Add "test" to UNIX
2167 sh_cmds[]. Fixes Savannah bug # 7606.
2169 2004-02-04 Paul D. Smith <psmith@gnu.org>
2171 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2172 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2173 Hartmut Becker <Hartmut.Becker@hp.com>.
2175 2004-01-21 Paul D. Smith <psmith@gnu.org>
2177 * job.c (load_too_high): Implement an algorithm to control the
2178 "thundering herd" problem when using -l to control job creation
2179 via the load average. The system only recomputes the load once a
2180 second but we can start many jobs in a second. To solve this we
2181 keep track of the number of jobs started in the last second and
2182 apply a weight to try to guess what a correct load would be.
2183 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2184 Also fixes bug #4693.
2185 (reap_children): Decrease the job count for this second.
2186 (start_job_command): Increase the job count for this second.
2188 * read.c (conditional_line): Expand the text after ifn?def before
2189 checking to see if it's a single word. Fixes bug #7257.
2191 2004-01-09 Paul D. Smith <psmith@gnu.org>
2193 * file.c (print_file): Recurse to print all targets in
2194 double-colon rules. Fixes bug #4518, reported (with patch) by
2195 Andrew Chatham <chatham@google.com>.
2197 2004-01-07 Paul D. Smith <psmith@gnu.org>
2199 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2200 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2201 AC_FUNC_SETVBUF_REVERSED.
2203 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2204 (MAKE Variable): Fix Savannah bug #4898.
2206 * job.c (construct_command_argv_internal): Add "!" to the list of
2207 shell escape chars. POSIX sh allows it to appear before a
2208 command, to negate the exit code. Fixes bug #6404.
2210 * implicit.c (pattern_search): When matching an implicit rule,
2211 remember which dependencies have the ignore_mtime flag set.
2212 Original fix provided in Savannah patch #2349, by Benoit
2213 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2215 2003-11-22 Paul D. Smith <psmith@gnu.org>
2217 * README.W32.template (Outputs): Clarification on -j with
2218 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2221 2003-11-02 Paul D. Smith <psmith@gnu.org>
2223 * function.c (func_if): Strip all the trailing whitespace from the
2224 condition, then don't expand it. Fixed bug # 5798.
2226 * expand.c (recursively_expand_for_file): If we're expanding a
2227 variable with no file context, then use the variable's context.
2230 2003-10-21 Paul D. Smith <psmith@gnu.org>
2232 * main.c (log_working_directory): Add newlines to printf()s.
2234 * README.cvs: Add a note to ignore warnings during autoreconf.
2236 * maintMakefile (po_repo): Set a new URL for PO file updates.
2237 (get-config/config.guess get-config/config.sub): Get these files
2238 from the Savannah config project instead of ftp.gnu.org.
2240 2003-10-05 Paul Eggert <eggert@twinsun.com>
2242 * main.c (main): Avoid potential subscript error if environ has
2245 2003-08-22 Paul D. Smith <psmith@gnu.org>
2247 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2248 systems which don't yet implement the C89 standard :-/.
2250 2003-07-18 Paul D. Smith <psmith@gnu.org>
2252 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2253 [WINDOWS32]: Initialize hash.
2255 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2257 * dir.c (read_dirstream): Provide a workaround for broken versions of
2258 the MinGW dirent structure.
2260 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2262 * w32/include/dirent.h: Add __MINGW32__ filter.
2264 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2266 * make.h: Add global declaration of *make_host.
2267 * main.c (print_usage): Remove local declaration of *make_host.
2268 (print_version): Display "This program built for ..." after Copyright
2271 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2273 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2274 execution of "makeinfo --html make.texi".
2276 2003-04-30 Paul D. Smith <psmith@gnu.org>
2278 * build.template: Make some changes to maybe allow this script to
2279 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2281 * README.OS2.template: New file for OS/2 support. Original
2282 contributed by Andreas Buening.
2283 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2286 2003-04-19 Paul D. Smith <psmith@gnu.org>
2288 Fix bug #1405: allow a target to match multiple pattern-specific
2291 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2292 variable.c, where they've always belonged.
2293 * rule.h: Move the prototypes and struct pattern_var as well.
2294 * variable.c (initialize_file_variables): Invoke
2295 lookup_pattern_var() in a loop, until no more matches are found.
2296 If a match is found, create a new variable set for the target's
2297 pattern variables. Then merge the contents of each matching
2298 pattern variable set into the target's pattern variable set.
2299 (lookup_pattern_var): Change this function to be usable
2300 in a loop. It takes a starting position: if NULL, start at the
2301 beginning; if non-NULL, start with the pattern variable after that
2302 position, and return the next matching pattern.
2303 (create_pattern_var): Create a unique instance of
2304 pattern-specific variables for every definition in the makefile.
2305 Don't combine the same pattern together. This allows us to
2306 process the variable handling properly even when the same pattern
2307 is used multiple times.
2308 (parse_variable_definition): New function: break out the parsing
2309 of a variable definition line from try_variable_definition.
2310 (try_variable_definition): Call parse_variable_definition to
2312 (print_variable_data_base): Print out pattern-specific variables.
2313 * variable.h (struct variable): Remember when a variable is
2314 conditional. Also remember its flavor.
2315 (struct pattern_var): Instead of keeping a variable set, we just
2316 keep a single variable for each pattern.
2317 * read.c (record_target_var): Each pattern variable contains only a
2318 single variable, not a set, so create it properly.
2319 * doc/make.texi (Pattern-specific): Document the new behavior.
2321 2003-04-17 Paul D. Smith <psmith@gnu.org>
2323 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2324 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2325 file/directory naming rules for VMS so I can't tell whether this
2328 2003-04-09 Paul D. Smith <psmith@gnu.org>
2330 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2331 DOS-style pathnames: backslash separators and drive specifiers.
2333 2003-03-28 Paul D. Smith <psmith@gnu.org>
2335 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2336 the intermediate flag on all targets. Fixes bug #2515.
2338 2003-03-24 Paul D. Smith <psmith@gnu.org>
2340 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2341 Upgrade to autoconf 2.57 and automake 1.7.3.
2343 * job.c: More OS/2 changes from Andreas Buening.
2345 * file.c (print_file): Fix variable initialization.
2348 * remake.c (notice_finished_file):
2350 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2351 some calls (like readdir()) return NULL in valid situations
2352 without resetting errno. Fixes bug #2846.
2354 2003-02-25 Paul D. Smith <psmith@gnu.org>
2356 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2358 * job.c (_is_unixy_shell) [OS/2]: New function.
2359 Set default shell to /bin/sh.
2360 (reap_children): Close the job_rfd pipe here since we don't use a
2362 (set_child_handler_action_flags): define this to empty on OS/2.
2363 (start_job_command): Close the jobserver pipe and use
2364 child_execute_job() instead of fork/exec.
2365 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2366 rather than exec'ing, then reconfigure stdin/stdout.
2367 (exec_command): Rewrite to use spawn instead of exec. Return the
2370 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2371 in DOS. Handle the TEMP environment variable as in DOS. Don't
2372 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2373 use -j in DOS mode. Use child_execute_job() instead of
2376 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2379 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2380 prototypes that return values.
2382 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2384 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2385 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2387 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2390 2003-02-24 Paul D. Smith <psmith@gnu.org>
2392 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2393 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2394 (child_execute_job) [VMS]: Handle error status properly.
2395 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2397 * function.c (func_shell): Use EINTRLOOP() while reading from the
2398 subshell pipe (Fixes bug #2502).
2399 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2401 * main.c (main): Ditto.
2403 2003-01-30 Paul D. Smith <psmith@gnu.org>
2405 * read.c (eval): eval() was not fully reentrant, because the
2406 collapsed buffer was static. Change it to be an automatic
2407 variable so that eval() can be invoked recursively.
2409 (eval): Apply patch # 1022: fix memory reference error on long
2410 target-specific variable lines.
2411 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2413 * function.c (check_numeric): Combine the is_numeric() function
2414 into this function, since it's only called from one place.
2415 Constify this function. Have it print the incorrect string in the
2416 error message. Fixes bug #2407.
2417 (strip_whitespace): Constify.
2418 (func_if): Constify.
2419 * expand.c (expand_argument): Constify.
2421 2003-01-29 Paul D. Smith <psmith@gnu.org>
2423 Fix bug # 2169, also reported by other people on various systems.
2425 * make.h: Some systems, such as Solaris and PTX, do not fully
2426 implement POSIX-compliant SA_RESTART functionality; important
2427 system calls like stat() and readdir() can still fail with EINTR
2428 even if SA_RESTART has been set on the signal handler. So,
2429 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2430 EINTR for system calls which return -1 or 0 (NULL), respectively,
2432 Also, remove the old atomic_stat()/atomic_readdir() and
2433 HAVE_BROKEN_RESTART handling.
2435 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2437 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2438 * remake.c (touch_file): Ditto.
2440 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2441 * read.c (construct_include_path): Ditto.
2442 * remake.c (name_mtime): Ditto.
2443 * vpath.c (selective_vpath_search): Ditto.
2444 * dir.c (find_directory): Ditto.
2445 (local_stat): Ditto.
2446 (find_directory): Use ENULLLOOP() to wrap opendir().
2447 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2449 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2450 atomic_readdir() handling.
2452 2003-01-22 Paul D. Smith <psmith@gnu.org>
2454 * function.c (func_call): Fix Bug #1744. If we're inside a
2455 recursive invocation of $(call ...), mask any of the outer
2456 invocation's arguments that aren't used by this one, so that this
2457 invocation doesn't "inherit" them accidentally.
2459 2002-12-05 Paul D. Smith <psmith@gnu.org>
2461 * function.c (subst_expand): Valery Khamenia reported a
2462 pathological performance hit when doing substitutions on very
2463 large values with lots of words: turns out we were invoking
2464 strlen() a ridiculous number of times. Instead of having each
2465 call to sindex() call strlen() again, keep track of how much of
2466 the text we've seen and pass the length to sindex().
2468 2002-11-19 Paul D. Smith <psmith@gnu.org>
2470 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2473 2002-11-16 Paul D. Smith <psmith@gnu.org>
2475 * NMakefile.template (OBJS): Add hash.c object file.
2476 * SMakefile.template (srcs): Ditto.
2477 * Makefile.ami (objs): Ditto.
2478 * build_w32.bat: Ditto.
2480 * Makefile.DOS.template: Remove extra dependencies.
2482 2002-10-25 Paul D. Smith <psmith@gnu.org>
2484 * expand.c (install_variable_buffer): New function. Install a new
2485 variable_buffer context and return the previous one.
2486 (restore_variable_buffer): New function. Free the current
2487 variable_buffer context and put a previously saved one back.
2488 * variable.h: Prototypes for {install,restore}_variable_buffer.
2489 * function.c (func_eval): Push a new variable_buffer context
2490 before we eval, then restore the old one when we're done.
2493 * read.c (install_conditionals): New function. Install a new
2494 conditional context and return the previous one.
2495 (restore_conditionals): New function. Free the current
2496 conditional context and put a previously saved one back.
2497 (eval): Use the {install,restore}_conditionals for "include"
2499 (eval_buffer): Use {install,restore}_conditionals to preserve the
2500 present conditional state before we evaluate the buffer.
2503 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2505 (Recursion): Add a variable index entry for CURDIR.
2507 * README.cvs: Update to appropriate versions.
2508 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2509 don't need to copy loadavg.c: automake is smart enough to create
2510 it for me. Still have a bug in automake related to ansi2knr tho.
2512 2002-10-14 Paul D. Smith <psmith@gnu.org>
2514 * remake.c (notice_finished_file): Only touch targets if they have
2515 at least one command (as per POSIX). Resolve Bug #1418.
2517 * *.c: Convert to using ANSI C-style function definitions.
2518 * Makefile.am: Enable the ansi2knr feature of automake.
2519 * configure.in: ditto.
2521 2002-10-13 Paul D. Smith <psmith@gnu.org>
2523 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2524 for automatic variable values like $^, etc. In the case of very
2525 large lists of prerequisites this causes problems. Instead reuse
2526 a static buffer (resizeable) for each variable.
2528 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2529 target-specific variable definitions. Check for it and set an
2531 (record_target_var): Set the export field to v_export if the
2532 "exported" flag is set.
2533 * doc/make.texi (Target-specific): Document the ability to use
2536 * doc/make.texi: Change the name of the section on automatic
2537 variables from "Automatic" to "Automatic Variables". Added text
2538 clarifying the scope of automatic variables.
2540 2002-10-04 Paul D. Smith <psmith@gnu.org>
2542 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2544 (record_files): Ditto.
2546 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2547 the search for the '=' to only within the enclosing parens.
2549 2002-10-03 Paul D. Smith <psmith@gnu.org>
2551 Version 3.80 released.
2553 * dir.c: Change hash functions to use K&R function definition style.
2554 * function.c: Ditto.
2556 * variable.c: Ditto.
2558 Update to automake 1.7.
2560 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2561 (pdf): Remove this target as automake now provides one.
2563 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2565 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2567 * makefile.com: Updates for GNU make 3.80.
2568 * makefile.vms: Ditto.
2570 2002-09-23 Paul D. Smith <psmith@gnu.org>
2572 * read.c (enum make_word_type): Remove w_comment.
2573 (get_next_mword): Don't treat comment characters as special; where
2574 this function is used we will never see a comment (it's stripped
2575 before we get here) and treating comments specially means that
2576 targets like "foo\#bar" aren't handled properly.
2578 2002-09-18 Paul D. Smith <psmith@gnu.org>
2580 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2582 * read.c (eval): Expansion of arguments to export/unexport was
2583 ignoring all arguments after the first one. Change the algorithm
2584 to expand the whole line once, then parse the results.
2586 2002-09-17 Paul D. Smith <psmith@gnu.org>
2588 Fix Bug #940 (plus another bug I found while looking at this):
2590 * read.c (record_target_var): enter_file() will add a new entry if
2591 it's a double-colon target: we don't want to do that in this
2592 situation. Invoke lookup_file() and only enter_file() if it does
2593 not already exist. If the file we get back is a double-colon then
2594 add this variable to the "root" double-colon target.
2596 * variable.c (initialize_file_variables): If this file is a
2597 double-colon target but is not the "root" target, then initialize
2598 the root and make the root's variable list the parent of our
2601 2002-09-13 Paul D. Smith <psmith@gnu.org>
2603 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2605 * hash.c (round_up_2): Get rid of a warning.
2607 2002-09-12 Paul D. Smith <psmith@gnu.org>
2609 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2610 so it doesn't complain about getloadavg.c.
2612 * commands.c (set_file_variables): Make sure we always alloca() at
2613 least 1 character for the value of $? (for '\0').
2615 2002-09-11 Paul D. Smith <psmith@gnu.org>
2617 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2618 macro to use RESULT instead of the incorrect _RESULT_.
2620 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2621 and atomic_readdir(). We need to #include dirent.h to get this to
2623 * misc.c (atomic_readdir): Fix typos.
2625 2002-09-10 Paul D. Smith <psmith@gnu.org>
2627 * read.c (eval): Expand variable lists given to export and
2628 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2629 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2631 * doc/make.texi (Variables/Recursion): Document this.
2632 (Conditional Syntax): And here.
2634 2002-09-09 Paul D. Smith <psmith@gnu.org>
2636 * configure.in: Check for memmove().
2638 2002-09-07 Paul D. Smith <psmith@gnu.org>
2640 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2641 Michael Sterrett <msterret@coat.com> reports that while it has
2642 SA_RESTART, it does not work properly.
2644 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2645 that invokes stat() and loops to do it again if it returns EINTR.
2646 (atomic_readdir): Ditto, with readdir().
2648 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2649 and readdir() to atomic_stat() and atomic_readdir().
2651 2002-09-04 Paul D. Smith <psmith@gnu.org>
2653 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2654 reports that GNU make sometimes doesn't recognize that targets can
2655 be made, when directories can be created as prerequisites. He
2656 reports that changing the order of predicates in the DEP->changed
2657 flag test so that lookup_file() is always performed, solves this
2660 2002-08-08 Paul D. Smith <psmith@gnu.org>
2662 * configure.in: Require a newer version of gettext.
2664 * misc.c (perror_with_name): Translate the format string (for
2665 right-to-left language support).
2666 (pfatal_with_name): Ditto.
2668 * main.c: Create a static array of strings to store the usage
2669 text. This is done to facilitate translations.
2670 (struct command_switch): Remove argdesc and description fields.
2671 (switches): Remove values for obsolete fields.
2672 (print_usage): Print each element of the usage array.
2674 * hash.c: Change function definitions to be K&R style.
2676 2002-08-02 Paul D. Smith <psmith@gnu.org>
2678 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2679 this one because it's too hard to get right. We'll look at it for
2681 * main.c (main): Don't create the .TARGETS variable.
2682 * variable.c (handle_special_var): Don't handle .TARGETS.
2684 2002-08-01 Paul D. Smith <psmith@gnu.org>

2688 if they don't appear to be out of date.
2689 (always_make_flag): New flag.
2690 * make.h: Extern always_make_flag.
2691 * remake.c (update_file_1): Check always_make_flag; if it's set we
2692 will always rebuild any target we can, even if none of its
2693 prerequisites are newer.
2696 * doc/make.texi (Shell Function): Make it clear that make
2697 variables marked as "export" are not passed to instances of the
2700 Add new introspection variable .VARIABLES and .TARGETS.
2702 * variable.c (handle_special_var): New function. If the variable
2703 reference passed in is "special" (.VARIABLES or .TARGETS),
2704 calculate the new value if necessary. .VARIABLES is handled here:
2705 walk through the hash of defined variables and construct a value
2706 which is a list of the names. .TARGETS is handled by
2707 build_target_list().
2708 (lookup_variable): Invoke handle_special_var().
2709 * file.c (build_target_list): Walk through the hask of known files
2710 and construct a list of the names of all the ones marked as
2712 * main.c (main): Initialize them to empty (and as simple variables).
2713 * doc/make.texi (Special Variables): Document them.
2714 * NEWS: Mention them.
2716 * variable.h (struct variable): Add a new flag "exportable" which
2717 is true if the variable name is valid for export.
2718 * variable.c (define_variable_in_set): Set "exportable" when a new
2719 variable is defined.
2720 (target_environment): Use the "exportable" flag instead of
2721 re-checking the name here... an efficiency improvement.
2723 2002-07-31 Paul D. Smith <psmith@gnu.org>
2725 * config.h-vms.template: Updates to build on VMS. Thanks to
2726 Brian_Benning@aksteel.com for helping verify the build.
2727 * makefile.com: Build the new hash.c file.
2728 * hash.h: Use strcpmi(), not stricmp(), in the
2729 HAVE_CASE_INSENSITIVE_FS case.
2731 2002-07-30 Paul D. Smith <psmith@gnu.org>
2733 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2734 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2735 Reported by <Brian_Benning@aksteel.com>.
2737 2002-07-10 Paul D. Smith <psmith@gnu.org>
2739 * variable.c (pop_variable_scope): Remove variable made unused by
2740 new hash infrastructure.
2741 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2742 comparisons as well as name comparisons.
2743 * variable.h: Add a prototype for new hash_init_function_table().
2744 * file.c (lookup_file): Remove variables made unused by new hash
2746 * dir.c (directory_contents_hash_2): Missing return of hash value.
2747 (dir_contents_file_exists_p): Remove variables made unused by new
2748 hash infrastructure.
2751 Installed Greg McGary's integration of the hash functions from the
2752 GNU id-utils package:
2754 2002-07-10 Greg McGary <greg@mcgary.org>
2756 * scripts/functions/filter-out: Add literals to to the
2757 pattern space in order to add complexity, and trigger
2758 use of an internal hash table. Fix documentation strings.
2759 * scripts/targets/INTERMEDIATE: Reverse order of files
2760 passed to expected `rm' command.
2762 2002-07-10 Greg McGary <greg@mcgary.org>

2854 2002-07-10 Paul D. Smith <psmith@gnu.org>
2856 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2857 prerequisite list. A real SysV make will expand the entire
2858 prerequisites list _twice_: we don't do that as it's a big
2859 backward-compatibility problem. We only replace those specific
2862 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2863 references left in the list of prerequisites. Check for .POSIX as
2864 we record targets, so we can disable non-POSIX behavior while
2865 reading makefiles as well as running them.
2866 (eval): Check the prerequisite list to see if we have anything
2867 that looks like a SysV prerequisite variable reference.
2869 2002-07-09 Paul D. Smith <psmith@gnu.org>
2871 * doc/make.texi (Prerequisite Types): Add a new section describing
2872 order-only prerequisites.
2874 * read.c (uniquize_deps): If we have the same file as both a
2875 normal and order-only prereq, get rid of the order-only prereq,
2876 since the normal one supersedes it.
2878 2002-07-08 Paul D. Smith <psmith@gnu.org>
2880 * AUTHORS: Added Greg McGary to the AUTHORS file.
2881 * NEWS: Blurbed order-only prerequisites.
2882 * file.c (print_file): Show order-only deps properly when printing
2885 * maintMakefile: Add "update" targets for wget'ing the latest
2886 versions of various external files. Taken from Makefile.maint in
2889 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2890 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2892 2002-07-07 Paul D. Smith <psmith@gnu.org>
2894 * po/*.po: Remove. We'll use wget to retrieve them at release
2897 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2898 rather than a shell you get an exception. Make sure we look up
2899 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2901 * remake.c (notice_finished_file): Fix handling of -t flag.
2902 Patch provided by Henning Makholm <henning@makholm.net>.
2904 * implicit.c (pattern_search): Some systems apparently run short
2905 of stack space, and using alloca() in this function caused an
2906 overrun. I modified it to use xmalloc() on the two variables
2907 which seemed like they might get large. Fixes Bug #476.
2909 * main.c (print_version): Update copyright notice to conform with
2911 (print_usage): Update help output.
2913 * function.c (func_eval): Create a new make function, $(eval
2914 ...). Expand the arguments, put them into a buffer, then invoke
2915 eval_buffer() on the resulting string.
2916 (func_quote): Create a new function, $(quote VARNAME). Inserts
2917 the value of the variable VARNAME without expanding it any
2920 * read.c (struct ebuffer): Change the linebuffer structure to an
2921 "eval buffer", which can be either a file or a buffer.
2922 (eval_makefile): Move the code in the old read_makefile() which
2923 located a makefile into here: create a struct ebuffer with that
2924 information. Have it invoke the new function eval() with that
2926 (eval_buffer): Create a new function that creates a struct ebuffer
2927 that holds a string buffer instead of a file. Have it invoke
2928 eval() with that ebuffer.
2929 (eval): New function that contains the guts of the old
2930 read_makefile() function: this function parses makefiles. Obtains
2931 data to parse from the provided ebuffer. Some modifications to
2932 make the flow of the function cleaner and clearer. Still could
2933 use some work here...
2934 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2935 contents of the define/endef variable from the ebuffer.
2936 (readstring): Read the next line from a string-style ebuffer.
2937 (readline): Read the next line from an ebuffer. If it's a string
2938 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2941 * dep.h (eval_buffer): Prototype eval_buffer();
2943 * variable.c (do_variable_definition): Make sure that all
2944 non-target-specific variables are registered in the global set.
2945 If we're invoked from an $(eval ...) we might be inside a $(call
2946 ...) or other function which has pushed a variable scope; we still
2947 want to define our variables from evaluated makefile code in the
2950 2002-07-03 Greg McGary <greg@mcgary.org>
2952 * dep.h (struct dep) [ignore_mtime]: New member.
2953 [changed]: convert to a bitfield.
2954 * implicit.c (pattern_search): Zero ignore_mtime.
2955 * main.c (main, handle_non_switch_argument): Likewise.
2956 * rule.c (convert_suffix_rule): Likewise.
2957 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2958 (read_makefile): Parse '|' in prerequisite list.
2959 (uniquize_deps): Consider ignore_mtime when comparing deps.
2960 * remake.c (update_file_1, check_dep): Don't force remake for
2961 dependencies that have d->ignore_mtime.
2962 * commands.c (FILE_LIST_SEPARATOR): New constant.
2963 (set_file_variables): Don't include a
2964 prerequisite in $+, $^ or $? if d->ignore_mtime.
2967 2002-06-18 Paul D. Smith <psmith@gnu.org>
2969 * make.texinfo: Updates for next revision. New date/rev/etc.
2970 Recreate all Info menus. Change license on the manual to the GNU
2971 Free Documentation License. A number of typos.
2972 (Variables Simplify): Don't use "-" before it's defined.
2973 (Automatic Prerequisites): Rewrite the target example to work
2974 properly if the compile fails. Remove incorrect comments about
2975 how "set -e" behaves.
2976 (Text Functions): Move the "word", "wordlist", "words", and
2977 "firstword" functions here, from "File Name Functions".
2978 * make-stds.texi: Update from latest GNU version.
2979 * fdl.texi: (created) Import the latest GNU version.
2981 2002-06-06 Paul D. Smith <psmith@gnu.org>
2983 * variable.c (do_variable_definition): New function: extract the
2984 part of try_variable_definition() that actually sets the value
2985 into a separate function.
2986 (try_variable_definition): Call do_variable_definition() after
2987 parsing the variable definition string.
2988 (define_variable_in_set): Make the name argument const.
2990 * variable.h (enum variable_flavor): Make public.
2991 (do_variable_definition): Create prototype.
2993 * read.c (read_all_makefiles): Create a new built-in variable,
2995 (read_makefile): Add each makefile read in to this variable value.
2997 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2999 * Makefile.DOS.template: Tweak according to changes in the
3000 distribution. Add back the dependencies of *.o files.
3002 * configh.dos.template: Synchronize with config.h.in.
3004 2002-05-09 Paul D. Smith <psmith@gnu.org>
3006 * file.c (file_timestamp_now): Use K&R function declaration.
3008 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3009 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3010 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3011 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3012 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3013 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3014 nlist.n_name is a pointer rather than an array.
3016 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3017 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3018 * configure.in: Use it instead of the old version.
3020 * main.c (main): Prefer setvbuf() to setlinebuf().
3022 2002-05-08 Paul D. Smith <psmith@gnu.org>
3024 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3025 (loadavg_LDADD): Ditto.
3027 2002-04-29 Paul D. Smith <psmith@gnu.org>
3029 * expand.c (recursively_expand_for_file): Rename
3030 recursively_expand() to recursively_expand_for_file() and provide
3031 an extra argument, struct file. If the argument is provided, set
3032 the variable scope to that of the file before expanding.
3033 * variable.h (recursively_expand): Make this a macro that invokes
3034 recursively_expand_for_file() with a NULL file pointer.
3035 * variable.c (target_environment): Call the renamed function and
3036 provide the current file context.
3037 Fixes Debian bug #144306.
3039 2002-04-28 Paul D. Smith <psmith@gnu.org>
3041 Allow $(call ...) user-defined variables to be self-referencing
3042 without throwing an error. Allows implementation of transitive
3043 closures, among other possibly useful things.
3044 Requested by: Philip Guenther <guenther@sendmail.com>
3046 * variable.h (struct variable): Add a new field: exp_count, and
3047 new macros to hold its size and maximum value.
3048 (warn_undefined): Make this a macro.
3049 * variable.c (define_variable_in_set): Initialize it.
3050 * expand.c (recursively_expand): If we detect recursive expansion
3051 of a variable, check the exp_count field. If it's greater than 0
3052 allow the recursion and decrement the count.
3053 (warn_undefined): Remove this (now a macro in variable.h).
3054 * function.c (func_call): Before we expand the user-defined
3055 function, modify its exp_count field to contain the maximum
3056 number of recursive calls we'll allow. After the call, reset it
3059 2002-04-21 Paul D. Smith <psmith@gnu.org>
3061 Modified to use latest autoconf (2.53), automake (1.6.1), and
3062 gettext (0.11.1). We're using gettext's new "external" support,
3063 to avoid including libintl source with GNU make.
3065 * README.cvs: New file. Explain how to build GNU make from CVS.
3067 * configure.in: Modify checking for the system glob library.
3068 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3069 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3070 etc. will manage it correctly). Set an automake conditional
3071 USE_LOCAL_GLOB to decide whether to compile the glob library.
3073 * getloadavg.c (main): Include make.h in the "TEST" program to
3076 * Makefile.am: Remove special rules for loadavg. Replace them
3077 with Automake capabilities for building extra programs.
3079 * signame.c: This file does nothing if the system provide
3080 strsignal(). If not, it implements strsignal(). If the system
3081 doesn't define sys_siglist, then we make our own; otherwise we use
3083 * signame.h: Removed.
3085 * main.c (main): No need to invoke signame_init(). Update copyright.
3087 * ABOUT-NLS: Removed.
3088 * gettext.c: Removed.
3089 * gettext.h: Get a simplified copy from the gettext package.
3091 * i18n/*.po: Moved to po/.
3094 * config/*: Created. Contains package configuration helper files.
3095 * config.guess, config.sub: Moved to config directory.
3097 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3098 Rework to use new-style autoconf features. Use the "external"
3099 mode for gettext. Make the build.sh config file conditional on
3100 whether build.sh.in exists, to avoid autoconf errors.
3101 * acinclude.m4: Removed almost all macros as being obsolete.
3102 Rewrote remaining macros to use AC_DEFINE.
3103 * acconfig.h: Removed.
3105 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3106 conditional to handle customs support. Remove special handling
3109 2002-04-20 Paul D. Smith <psmith@gnu.org>
3111 * function.c (func_call): Don't mark the argument variables $1,
3112 etc. as recursive. They've already been fully expanded so
3113 there's no need to do it again, and doing so strips escaped $'s.
3114 Reported by Sebastian Glita <glseba@yahoo.com>.
3116 * remake.c (notice_finished_file): Walk through double-colon

3118 Reported by Greg McGary <greg@mcgary.org>.
3120 * main.c (main): If the user specifies -q and asks for a specific
3121 target which is a makefile, we got an assert. In that case it
3122 turns out we should continue normally instead.
3124 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3126 * i18n/he.po: Installed a new translation.
3128 2002-01-07 Paul D. Smith <psmith@gnu.org>

3138 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3139 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3141 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit

3152 Resolves Debian bug #106720.
3154 2001-06-13 Paul D. Smith <psmith@gnu.org>
3156 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3159 2001-06-11 Paul D. Smith <psmith@gnu.org>
3161 * i18n/ko.po: Installed a new translation.
3163 2001-05-06 Paul D. Smith <psmith@gnu.org>
3165 Modify the EINTR handling.
3167 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3168 the way in which we manage the file descriptor/signal handler race
3169 trap to be more efficient.
3171 2001-05-06 Paul Eggert <eggert@twinsun.com>
3173 Restart almost all system calls that are interrupted, instead
3174 of worrying about EINTR. The lone exception is the read() for
3177 * configure.in (HAVE_SA_RESTART): New macro.
3178 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3179 * main.c (main): Use SA_RESTART instead of the old,
3180 nonstandard SA_INTERRUPT.
3182 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3183 * main.c (bsd_signal): New function or macro,
3184 if the implementation doesn't supply it.
3185 (The bsd_signal function will be in POSIX 1003.1-200x.)
3186 (HANDLESIG): Remove.
3187 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3189 * make.h (EINTR_SET): Remove.
3190 (SA_RESTART): New macro.
3192 * arscan.c (ar_member_touch): Don't worry about EINTR.
3193 * function.c (func_shell): Likewise.
3194 * job.c (reap_children, free_child, new_job): Likewise.
3195 * main.c (main): Likewise.
3196 * remake.c (touch_file, name_mtime): Likewise.
3198 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3199 if fstat failed with errno!=EINTR, the error was ignored.
3201 * job.c (set_child_handler_action_flags): New function.
3202 (new_job): Use it to temporarily clear the SIGCHLD action flags
3203 while reading the token.
3205 2001-05-02 Paul D. Smith <psmith@gnu.org>
3207 * job.c (start_job_command): Don't add define/endef per-line flags
3208 to the top-level flags setting.
3210 2001-04-03 Paul D. Smith <psmith@gnu.org>
3212 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3213 bit on error, so check for odd return values, not non-0 return
3215 (VMS_get_member_info): Calculate the timezone differences correctly.
3216 Reported by John Fowler <jfowler@nyx.net>.
3219 2001-03-14 Paul D. Smith <psmith@gnu.org>
3221 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3222 value before invoking define_variable().
3223 Reported by John Fowler <jfowler@nyx.net>.
3225 2001-02-07 Paul D. Smith <psmith@gnu.org>
3227 * read.c (record_target_var): If we reset the variable due to a
3228 command-line variable setting overriding it, turn off the "append"
3231 2001-01-17 Paul D. Smith <psmith@gnu.org>
3233 * variable.c (lookup_variable) [VMS]: When getting values from the
3234 environment, allocate enough space for the _value_ plus escapes,
3235 not enough space for the name plus escapes :-/.
3236 Reported by John Fowler <jfowler@nyx.net>.
3238 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3239 warnings that make generates, so it doesn't look like an error.
3240 Reported by Karl Berry <karl@gnu.org>.
3243 Fix for PR/2020: Rework appended target-specific variables. I'm
3244 fairly confident this algorithm is finally correct.
3246 * expand.c (allocated_variable_append): Rewrite. Instead of
3247 expanding each appended variable then adding all the expanded
3248 strings together, we append all the unexpanded values going up
3249 through the variable set contexts, then expand the final result.
3250 This behaves just like non-target-specific appended variable
3251 values, while the old way didn't in various corner cases.
3252 (variable_append): New function: recursively append the unexpanded
3253 value of a variable, walking from the outermost variable scope to
3255 * variable.c (lookup_variable): Remove the code that looked up the
3256 variable set list if the found variable was "append". We don't
3258 (lookup_variable_in_set): Make this non-static so we can use it
3260 (try_variable_definition): Use lookup_variable_in_set() rather
3261 than faking out current_variable_set_list by hand (cleanup).
3262 * variable.h: Add a prototype for the now non-static
3263 lookup_variable_in_set().
3265 2000-11-17 Paul D. Smith <psmith@gnu.org>
3267 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3268 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3269 before throwing a fit.
3271 2000-11-17 Paul D. Smith <psmith@gnu.org>
3273 * read.c (readline): CRLF calculations had a hole, if you hit the
3274 buffer grow scenario just right. Reworked the algorithm to avoid
3275 the need for len or lastlen at all. Problem description with
3276 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3278 2000-10-24 Paul D. Smith <psmith@gnu.org>
3280 * gettext.c (SWAP): Declare this with the prototype, otherwise
3281 some systems don't work (non-32-bit? Reported for Cray T3E).
3282 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3284 2000-10-05 Paul D. Smith <psmith@gnu.org>
3286 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3287 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3289 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3291 2000-09-22 Paul D. Smith <psmith@gnu.org>
3293 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3294 parts of the real gettext.h here, and we expect to really include
3295 the real gettext.h later. If we keep this #define, it's ignored.
3297 2000-09-21 Paul D. Smith <psmith@gnu.org>
3299 * main.c (log_working_directory): Rework the text to use complete
3300 sentences, to make life simpler for the translators.
3302 2000-08-29 Paul D. Smith <psmith@gnu.org>
3304 * file.c (remove_intermediates): Print a debug message before we
3305 remove intermediate files, so the user (if she uses -d) knows
3308 2000-08-21 Paul D. Smith <psmith@gnu.org>
3310 * variable.c (try_variable_definition): Change how we handle
3311 target-specific append variable defns: instead of just setting the
3312 value, expand it as an append _but_ only within the current
3313 target's context. Otherwise we lose all but the last value if the
3314 variable is appended more than once within the current target
3315 context. Fixes PR/1831.
3317 2000-08-16 Paul D. Smith <psmith@gnu.org>
3319 * function.c (func_shell): Nul-terminate the buffer before
3320 printing an exec error message (just in case it's not!).
3321 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3323 2000-07-25 Paul D. Smith <psmith@gnu.org>
3325 * job.c (construct_command_argv_internal): Add "~" to the list of
3326 sh_chars[] which disallow optimizing out the shell call.
3328 2000-07-23 Paul Eggert <eggert@twinsun.com>
3330 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3331 supersedes --disable-nsec-timestamps.
3332 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3333 * README: Remove --disable-nsec-timestamps.
3335 * filedef.h (struct file.low_resolution_time): New member.
3336 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3337 * remake.c (update_file_1):
3338 Avoid spurious rebuilds due to low resolution time stamps,
3339 generalizing the earlier code that applied only to archive members.
3340 (f_mtime): Archive members always have low resolution time stamps.
3342 * configure.in: Remove --disable-nsec-timestamps, as this has
3343 been superseded by .LOW_RESOLUTION_TIME.
3345 2000-07-23 Paul Eggert <eggert@twinsun.com>
3347 * configure.in (enable_nsec_timestamps): Renamed from
3348 make_cv_nsec_timestamps, since enable/disable options
3349 shouldn't be cached.
3351 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3352 and Paul Eggert <eggert@twinsun.com>
3354 * file.c (file_timestamp_now):
3355 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3356 so that clock_gettime is not linked unless needed.
3358 * filedef.h (FILE_TIMESTAMP_HI_RES):
3359 Remove definition; "configure" now does this.
3361 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3362 to before high resolution file timestamp check,
3363 since that check now uses uintmax_t.
3364 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3365 high resolution file timestamps.
3366 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3367 so that we don't link in clock_gettime unnecessarily.
3369 2000-07-17 Paul D. Smith <psmith@gnu.org>
3371 * i18n/ja.po: New version of the translation file.
3373 2000-07-07 Paul D. Smith <psmith@gnu.org>
3375 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3376 the offset calculation.
3377 (name_mtime): Replace EINTR test with EINTR_SET macro.
3379 2000-07-07 Paul Eggert <eggert@twinsun.com>
3383 * remake.c (update_file_1):
3384 Avoid spurious rebuilds of archive members due to their
3385 timestamp resolution being only one second.
3386 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3387 the clock's resolution being lower than file timestamps'.
3388 When warning about future timestamps, report only the discrepancy,
3389 not the absolute value of the timestamp and the current time.
3391 * file.c (file_timestamp_now): New arg RESOLUTION.
3392 * filedef.h (file_timestamp_now): Likewise.
3393 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3395 2000-07-05 Paul D. Smith <psmith@gnu.org>
3397 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3398 to listp. Fixes PR/1793.
3400 2000-06-26 Paul Eggert <eggert@twinsun.com>
3402 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3404 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3406 * remake.c (f_mtime): Remove unused var memtime.
3408 2000-06-25 Martin Buchholz <martin@xemacs.org>
3410 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3411 Ran spell-check on make.texinfo.
3413 2000-06-23 Paul D. Smith <psmith@gnu.org>
3415 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3416 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3417 * make.h: Define these macros.
3419 * Version 3.79.1 released.
3421 * configure.in: Add a new option, --disable-nsec-timestamps, to
3422 avoid using sub-second timestamps on systems that support it. It
3423 can lead to problems, e.g. if your makefile relies on "cp -p".
3424 * README.template: Document the issue with "cp -p".
3426 * config.guess, config.sub: Updated.
