1 2007-10-12 Eli Zaretskii <eliz@gnu.org>
3 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
4 a more complex value than a simple shell: if it's not a default
5 shell now then expand it and see if is a default shell then.
7 2007-10-10 Eli Zaretskii <eliz@gnu.org>
9 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
10 pathnames, with const strings.
11 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
12 from the template (used for building from CVS, not a dist).
14 2007-10-10 Paul Smith <psmith@gnu.org>
16 * make.h: Add a prototype for w32_kill() (change suggested by
17 Yongwei Wu <wuyongwei@gmail.com>).
19 2007-09-21 Eli Zaretskii <eliz@gnu.org>
21 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
22 directories in Path.
24 2007-08-15 Paul Smith <psmith@gnu.org>
26 * doc/make.texi (GNU Free Documentation License): The fdl.texi
27 file has had the section info removed, so add some to make.texi
28 before we include it.
30 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
32 * remake.c (check_dep): Reset the target state for intermediate
33 files. They might have been considered before but not updated
34 then (order-only for example) but they will be this time.
35 Fixes Savannah bug #'s 3330 and 15919.
37 2007-07-21 Eli Zaretskii <eliz@gnu.org>
39 Fix Savannah bug #20549:
40 * function.c (func_shell): Call construct_command_argv with zero
41 value of FLAGS.
42 * job.c (construct_command_argv_internal): New argument FLAGS; all
43 callers changed.
44 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
45 just_print_flag.
46 * job.h (construct_command_argv_internal): Update prototype.
48 2007-07-13 Paul Smith <psmith@gnu.org>
50 * file.c (expand_deps): Use variable_buffer as the start of the
51 buffer, not the original pointer (in case it was reallocated).
52 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
53 Fixes Savannah bug #20452.
55 2007-07-04 Paul Smith <psmith@gnu.org>
57 * (ALL FILES): Update to GPLv3.

68 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
69 "Expansion of a deferred"
70 Fixes Savannah bug #20018.
72 * expand.c (variable_expand_for_file): Preserve the value of
73 reading_file rather than setting it to 0 at the end.
74 Fixes Savannah bug #20033.
76 2007-05-11 Paul Smith <psmith@gnu.org>
78 * job.c (new_job): Add debug info to specify where make found the
79 command script it is running to build a target.
80 Fixes Savannah bug #18617.
82 * default.c (default_suffixes,default_suffix_rules,default_variables):
83 Add support for Objective C. Fixes Savannah bug #16389.
84 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
86 * function.c (func_lastword): Initialize p.
88 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
89 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
90 Dave Korn <dave.korn@artimi.com>
92 2007-05-08 Paul Smith <psmith@gnu.org>
94 Fix Savannah bug #19656:
96 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
98 * make.h: Change all case-insensitive string compares to use
99 strcasecmp() (from POSIX). If we don't have that but do have one
100 of the others, define strcasecmp to be one of those instead. If
101 we don't have any, declare a prototype for our own version.
103 * misc.c (strcasecmp): Use this if we can't find any native
104 case-insensitive string comparison function.
105 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
106 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
107 strcmpi().
108 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
109 strcasecmp() instead of stricmp().
110 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
111 instead of strcmpi().
112 * acinclude.m4: Remove the strcasecmp() check from here.
114 2007-03-21 Paul Smith <psmith@gnu.org>
116 * configure.in: Don't turn on case-insensitive file system support
117 if --disable-... is given. Fixes Savannah bug #19348.
119 2007-03-19 Paul Smith <psmith@gnu.org>
121 * ALL: Use the strcache for all file name strings, or other
122 strings which we will never free. The goal is to save memory by
123 avoiding duplicate copies of strings. However, at the moment this
124 doesn't save much memory in most situations: due to secondary
125 expansion we actually save prerequisite lists twice (once before
126 the secondary expansion, and then again after it's been parsed
127 into individual file names in the dep list). We will resolve this
128 in a future change, by doing the parsing up-front for targets
129 where secondary expansion is not set.
131 Moving things into the strcache also allows us to use const
132 pointers in many more places.
134 2007-01-03 Paul Smith <psmith@gnu.org>
136 * make.h (ENULLLOOP): Reset errno after each failed invocation of
137 the function, not just the first. Fixes Savannah bug #18680.
139 2006-11-18 Paul Smith <psmith@gnu.org>
141 * strcache.c (strcache_add_len): Don't allocate a new buffer
142 unless the string is not already nil-terminated. Technically this
143 is a violation of the standard, since we may be passed an array
144 that is not long enough to test one past. However, in make this
145 is never true since we only use nil-terminated strings or
146 sub-strings thereof.
148 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
150 * main.c: New global cmd_prefix, defaults to '\t'.
151 * job.c (construct_command_argv_internal): Use cmd_prefix instead
152 of '\t'.
154 * dir.c: Constified.
155 (dir_contents_file_exists_p): Check for an error return from
156 readdir(), just in case.
158 * commands.c: Constified.
159 * default.c: Constified.
160 * expand.c: Constified.
161 * function.c: Partial constification.
162 * variable.c: Partial constification.
163 * vmsify.c: Constification. Hard to test this but I hope I didn't
164 screw it up!
165 * vpath.c: Partial constification.
166 * w32/pathstuff.c: Partial constification.
168 2006-11-16 Eli Zaretskii <eliz@gnu.org>
170 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
171 backslashes and drive letters as absolute.
173 2006-10-22 Paul Smith <psmith@gnu.org>
175 * main.c (struct command_switch): Use const and void*.
177 2006-10-21 Paul Smith <psmith@gnu.org>
179 * ar.c: Constified.
180 * arscan.c: Constified.
182 2006-09-30 Paul Smith <psmith@gnu.org>
184 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
185 point to lastword since the example was updated.
186 Fixes Savannah bug #16304.
187 (Secondary Expansion): Correct example description.
188 Fixes Savannah bug #16468.
189 (Makefile Contents): Clarify that comments cannot appear within
190 variable references or function calls.
191 Fixes Savannah bug #16577.
192 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
193 Fixes Savannah bug #17701.
194 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
195 (Prerequisite Types): Added an example of using order-only
196 prerequisites. Fixes Savannah bug #17880.
197 (Rule Syntax): "lise" -> "list"
198 (Multiple Rules): ... -> @dots{}
199 (Splitting Lines): ditto.
201 * remake.c (update_file_1): Prereqs that don't exist should be
202 considered changed, for the purposes of $?.
203 Fixes Savannah bug #16051.
205 * make.1: Remove extraneous "+".
206 Fixes Savannah bug #16652.

212 2006-08-18 Eli Zaretskii <eliz@gnu.org>
214 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
215 $PATH_SEPARATOR.
217 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
218 Normally, it is defined in config.h.
220 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
221 well.
223 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
224 sh_chars_sh for Windows platforms that emulate Unix.
226 2006-05-07 Paul D. Smith <psmith@gnu.org>

238 * README.cvs: Add a reminder to notify the GNU translation robot.
240 * doc/make.texi: Change @direcategory (requested by Karl Berry).
242 2006-04-20 Paul D. Smith <psmith@gnu.org>
244 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
245 that don't have extended grep.
246 (cvsclean): Use $(PERL) instead of perl.
248 2006-04-09 Paul D. Smith <psmith@gnu.org>
250 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
252 * expand.c, implicit.c, main.c, read.c: Rename variables so that
253 inner-scope variables don't mask outer-scope variables.
255 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
256 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
257 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
258 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
259 values from memory allocation functions: they return void* and so
260 don't need to be cast. Also remove (char *) casts of arguments to
261 xrealloc().
263 * configure.in: Remove checks for memcpy/memmove/strchr.
265 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

275 2006-04-06 Paul D. Smith <psmith@gnu.org>
277 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
278 require an ISO C 1989 standard compiler and runtime library.
280 * Makefile.am: Remove the ansi2knr feature.
282 * make.h: Remove the PARAMS() macro definition and all uses of it.
284 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.

288 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
290 * NEWS: Update.
292 2006-04-01 Paul D. Smith <psmith@gnu.org>
294 Version 3.81 released.
296 * NEWS: Updated for 3.81.
298 * README.cvs: Mention that vpath builds are not supported out of
299 CVS. Fixes Savannah bug #16236.
300 Remove update of make.texi from the list of things to do; we use
301 version.texi now.
303 2006-03-26 Paul D. Smith <psmith@gnu.org>
305 * doc/make.texi: Clean up licensing. Use @copying and version.texi
306 support from automake, as described in the Texinfo manual.
308 2006-03-25 Eli Zaretskii <eliz@gnu.org>
310 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
311 with lastslash, since the latter points to filename, not to
312 target.
313 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
314 Declare and define sh_chars_sh[].
316 2006-03-23 Paul D. Smith <psmith@gnu.org>
318 * configure.in: Look for build.sh.in in $srcdir so it will be
319 built for remote configurations as well.
321 * Makefile.am: Make sure to clean up build.sh during distclean.
322 Fixes Savannah bug #16166.
324 * misc.c (log_access): Takes a const char *.
325 * function.c (fold_newlines): Takes an unsigned int *.
326 Both fixes for Savannah bug #16170.
328 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
330 * implicit.c (pattern_search): Call set_file_variables only
331 if we have prerequisites that need second expansion. Fixes
332 Savannah bug #16140.
334 2006-03-19 Paul D. Smith <psmith@gnu.org>
336 * remake.c (update_file): Add alloca(0) to clean up alloca'd
337 memory on hosts that don't support it directly.
339 * README.cvs: Add information on steps for making a release (to
340 make sure I don't forget any).
342 * main.c (clean_jobserver): Move jobserver cleanup code into a new
343 function.
344 (die): Cleanup code was removed from here; call the new function.
345 (main): If we are re-execing, clean up the jobserver first so we
346 don't leak file descriptors.
347 Reported by Craig Fithian <craig.fithian@citigroup.com>
349 2006-03-17 Paul D. Smith <psmith@gnu.org>
351 * maintMakefile (do-po-update): Rewrite this rule to clean up and
352 allow multiple concurrent runs.
353 Patch from Joseph Myers <joseph@codesourcery.com>
355 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
357 * dep.h (struct dep): Add the stem field.
358 * misc.c (alloc_dep, free_dep): New functions.
359 (copy_dep_chain): Copy stem.
360 (free_dep_chain): Use free_dep.
361 * read.c (record_files): Store stem in the dependency line.
362 * file.c (expand_deps): Use stem stored in the dependency line. Use
363 free_dep_chain instead of free_ns_chain.
364 * implicit.c (pattern_search): Use alloc_dep and free_dep.
365 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
366 * main.c (main, handle_non_switch_argument): Ditto.
367 * remake.c (check_dep): Ditto.
368 * rule.c (convert_suffix_rule, freerule): Ditto.
370 2006-03-14 Paul D. Smith <psmith@gnu.org>
372 * expand.c (variable_append): Instead of appending everything then
373 expanding the result, we expand (or not, if it's simple) each part
374 as we add it.
375 (allocated_variable_append): Don't expand the final result.
376 Fixes Savannah bug #15913.
378 2006-03-09 Paul Smith <psmith@gnu.org>
380 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
381 listed non-existent files as changed. Turns out there's a bug in
382 the Linux kernel builds which means that this change causes
383 everything to rebuild every time. We will re-introduce this fix
384 in the next release, to give them time to fix their build system.
385 Fixes Savannah bug #16002.
386 Introduces Savannah bug #16051.
388 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
389 we *don't* find UNIX "/".
390 Reported by David Ergo <david.ergo@alterface.com>
392 2006-03-04 Eli Zaretskii <eliz@gnu.org>
394 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
395 locator function find_and_set_default_shell if SHELL came from the
396 command line.
398 2006-02-20 Paul D. Smith <psmith@gnu.org>
400 * variable.c (merge_variable_set_lists): It's legal for *setlist0
401 to be null; don't core in that case.
403 2006-02-19 Paul D. Smith <psmith@gnu.org>
405 * commands.c (set_file_variables): Realloc, not malloc, the static
406 string values to avoid memory leaks.
408 * expand.c (recursively_expand_for_file): Only set reading_file to
409 an initialized value.
411 * implicit.c (pattern_search): We need to make a copy of the stem
412 if we get it from an intermediate dep, since those get freed.
414 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
415 begin with ".".
416 (enter_file) [VMS]: Ditto.
417 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
419 2006-02-24 Eli Zaretskii <eliz@gnu.org>
421 * job.c (construct_command_argv_internal): Fix last change.
423 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
424 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
425 the calls to _beginthreadex.
427 * expand.c (recursively_expand_for_file): Initialize `save' to
428 prevent compiler warnings.
430 2006-02-18 Eli Zaretskii <eliz@gnu.org>
432 * job.c (construct_command_argv_internal): Don't create a temporary
433 script/batch file if we are under -n. Call _setmode to switch the
434 script file stream to text mode.
436 2006-02-17 Paul D. Smith <psmith@gnu.org>
438 * variable.c (merge_variable_set_lists): Don't try to merge the
439 global_setlist. Not only is this useless, but it can lead to
440 circularities in the linked list, if global_setlist->next in one
441 list gets set to point to another list which also ends in
442 global_setlist.
443 Fixes Savannah bug #15757.
445 2006-02-15 Paul D. Smith <psmith@gnu.org>
447 Fix for Savannah bug #106.
449 * expand.c (expanding_var): Keep track of which variable we're
450 expanding. If no variable is being expanded, it's the same as
451 reading_file.
452 * make.h (expanding_var): Declare it.
453 * expand.c (recursively_expand_for_file): Set expanding_var to the
454 current variable we're expanding, unless there's no file info in
455 it (could happen if it comes from the command line or a default
456 variable). Restore it before we exit.
457 * expand.c (variable_expand_string): Use the expanding_var file
458 info instead of the reading_file info.
459 * function.c (check_numeric): Ditto.
460 (func_word): Ditto.
461 (func_wordlist): Ditto.
462 (func_error): Ditto.
463 (expand_builtin_function): Ditto.
464 (handle_function): Ditto.
466 2006-02-14 Paul D. Smith <psmith@gnu.org>
468 * read.c (eval): Even if the included filenames expands to the
469 empty string we still need to free the allocated buffer.
471 * implicit.c (pattern_search): If we allocated a variable set for
472 an impossible file, free it.
473 * variable.c (free_variable_set): New function.
474 * variable.h: Declare it.
476 * read.c (read_all_makefiles): Makefile names are kept in the
477 strcache, so there's never any need to alloc/free them.
478 (eval): Ditto.
480 * main.c (main): Add "archives" to the .FEATURES variable if
481 archive support is enabled.
482 * doc/make.texi (Special Variables): Document it.
484 2006-02-13 Paul D. Smith <psmith@gnu.org>
486 * implicit.c (pattern_search): Add checking for DOS pathnames to
487 the pattern rule target LASTSLASH manipulation.
488 Fixes Savannah bug #11183.
490 2006-02-11 Paul D. Smith <psmith@gnu.org>
492 * (ALL FILES): Updated copyright and license notices.
494 2006-02-10 Paul D. Smith <psmith@gnu.org>
496 A new internal capability: the string cache is a read-only cache
497 of strings, with a hash table interface for fast lookup. Nothing
498 in the cache will ever be freed, so there's no need for reference
499 counting, etc. This is the beginning of a full solution for
500 Savannah bug #15182, but for now we only store makefile names here.
502 * strcache.c: New file. Implement a read-only string cache.
503 * make.h: Add prototypes for new functions.
504 * main.c (initialize_global_hash_tables): Initialize the string cache.
505 (print_data_base): Print string cache stats.
506 * read.c (eval_makefile): Use the string cache to store makefile
507 names. Rewrite the string allocation to be sure we free everything.
509 2006-02-10 Eli Zaretskii <eliz@gnu.org>
511 * dir.c (dir_contents_file_exists_p): Don't opendir if the
512 directory time stamp didn't change, except on FAT filesystems.
513 Suggested by J. David Bryan <jdbryan@acm.org>.
515 2006-02-09 Paul D. Smith <psmith@gnu.org>
517 * function.c (func_or): Implement a short-circuiting OR function.
518 (func_and): Implement a short-circuiting AND function.
519 (function_table_init): Update the table with the new functions.
520 * doc/make.texi (Conditional Functions): Changed the "if" section
521 to one on general conditional functions. Added documentation for
522 $(and ...) and $(or ...) functions.
523 * NEWS: Note new $(and ...) and $(or ...) functions.
525 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
527 * job.h (struct child): Add the dontcare bitfield.
528 * job.c (new_job): Cache dontcare flag.
529 * job.c (reap_children): Use cached dontcare flag instead of the
530 one in struct file. Fixes Savannah bug #15641.
532 2006-02-06 Paul D. Smith <psmith@gnu.org>
534 * vpath.c (selective_vpath_search): If the file we find has a
535 timestamp from -o or -W, use that instead of the real time.
536 * remake.c (f_mtime): If the mtime is a special token from -o or
537 -W, don't overwrite it with the real mtime.
538 Fixes Savannah bug #15341.
540 Updates from Markus Mauhart <qwe123@chello.at>:
542 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
543 (process_signal, process_last_err, process_exit_code): Manage
544 invalid handle values.
545 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
546 manage invalid handles; remove them.
547 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
548 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
549 * README.cvs: Updates for building from CVS.
551 2006-02-05 Paul D. Smith <psmith@gnu.org>
553 * file.c (enter_file): Keep track of the last double_colon entry,
554 to avoid walking the list every time we want to add a new one.
555 Fixes Savannah bug #15533.
556 * filedef.h (struct file): Add a new LAST pointer.
558 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
559 the comparison. For 64-bits systems the result of the subtraction
560 might not fit into an int. Use comparison instead.
561 Fixes Savannah bug #15534.
563 * doc/make.texi: Update the chapter on writing commands to reflect
564 the changes made in 3.81 for backslash/newline and SHELL handling.
566 2006-02-01 Paul D. Smith <psmith@gnu.org>
568 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
569 variable st is not used when it's not initialized.
570 Patch from Eli Zaretskii <eliz@gnu.org>.
572 2006-01-31 Paul D. Smith <psmith@gnu.org>
574 * README.W32.template: Applied patch #4785 from
575 Markus Mauhart <qwe123@chello.at>.

579 J. Grant <jg@jguk.org>.
581 * main.c: Update the copyright year in the version output.
582 * prepare_w32.bat: Remove this file from the distribution.
584 2006-01-21 Eli Zaretskii <eliz@gnu.org>
586 * remake.c (update_goal_chain): Set g->changed instead of
587 incrementing it, as it is only 8-bit wide, and could overflow if
588 many commands got started in update_file.
590 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
592 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
593 MAXIMUM_WAIT_OBJECTS.
594 (process_wait_for_any_private): Change dimension of handles[]
595 array to MAXIMUM_WAIT_OBJECTS.
596 (process_used_slots): New function.
597 (process_register): Don't register more processes than the
598 available number of slots.
599 (process_easy): Don't start new processes if all slots are used up.
601 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
602 are already more children than sub_proc.c can handle, behave as if
603 the load were too high.
604 (start_job_command): Fix a typo in error message when process_easy
605 fails.
607 2006-01-14 Eli Zaretskii <eliz@gnu.org>
609 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
610 the shell is not sh.exe.
612 * job.c (create_batch_file): Renamed from create_batch_filename;
613 all callers changed. Don't close the temporary file; return its
614 file descriptor instead. New arg FD allows to return the file
615 descriptor.
616 (construct_command_argv_internal): Use _fdopen instead of fopen to
617 open the batch file.
619 2006-01-04 Paul D. Smith <psmith@gnu.org>
621 * readme.vms: Updates for case-insensitive VMS file systems from
622 Hartmut Becker <Hartmut.Becker@hp.com>.
623 * dir.c (vms_hash): Ditto.
624 * vmsify.c (copyto): Ditto.
625 * vmsfunctions.c (readdir): Ditto.
627 * make.1: Add a section on the exit codes for make.

631 2006-01-03 Paul D. Smith <psmith@gnu.org>
633 * remake.c (update_file_1): Mark a prerequisite changed if it
634 doesn't exist.
636 * read.c (eval): Be sure to strip off trailing whitespace from the
637 prerequisites list properly. Also, initialize all fields in
638 struct dep when creating a new one.
640 2005-12-28 Paul D. Smith <psmith@gnu.org>
642 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
643 disable warnings for MSC.
644 Patch by Rob Tulloh <rtulloh@yahoo.com>.
646 2005-12-17 Eli Zaretskii <eliz@gnu.org>
648 * doc/make.texi (Execution): Add a footnote about changes in
649 handling of backslash-newline sequences. Mention the differences
650 on MS-DOS and MS-Windows.
652 * NEWS: More details about building the MinGW port and a pointer
653 to README.W32. Fix the section name that describes the new
654 backward-incompatible processing of backslash-newline sequences.
655 The special processing of SHELL set to "cmd" is only relevant to
656 MS-Windows, not MS-DOS.
658 2005-12-17 Eli Zaretskii <eliz@gnu.org>
660 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
661 to DWORD, to avoid compiler warnings.
662 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
663 use %ld in format, to avoid compiler warnings.
665 * doc/make.texi (Special Targets): Fix a typo.
666 (Appending): Fix cross-reference to Setting.
667 (Special Variables, Secondary Expansion, File Name Functions)
668 (Flavor Function, Pattern Match, Quick Reference): Ensure two
669 periods after a sentence.
670 (Execution): Add @: after "e.g.".
671 (Environment): Fix punctuation.
672 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
673 (Shell Function, Target-specific): Add @: after "vs."
675 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
677 * read.c (record_target_var): Initialize variable's export field
678 with v_default instead of leaving it "initialized" by whatever
679 garbage happened to be on the heap.
681 2005-12-12 Paul D. Smith <psmith@gnu.org>
683 * make.1: Fix some display errors and document all existing options.
684 Patch provided by Mike Frysinger <vapier@gentoo.org>.
686 2005-12-11 Paul D. Smith <psmith@gnu.org>
688 * implicit.c (pattern_search): If 2nd expansion is not set for
689 this implicit rule, replace the pattern with the stem directly,
690 and don't re-expand the variable list. Along with the other
691 .SECONDEXPANSION changes below, fixes bug #13781.
693 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
695 * implicit.c (pattern_search): Mark other files that this rule
696 builds as targets so that they are not treated as intermediates
697 by the pattern rule search algorithm. Fixes bug #13022.
699 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
701 * remake.c (notice_finished_file): Propagate the change of
702 modification time to all the double-colon entries only if
703 it is the last one to be updated. Fixes bug #14334.
705 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
707 * function.c (func_flavor): Implement the flavor function which
708 returns the flavor of a variable.
709 * doc/make.texi (Functions for Transforming Text): Document it.
710 * NEWS: Add it to the list of new functions.
712 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
714 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
715 variable.
716 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
717 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
719 2005-10-26 Paul Smith <psmith@gnu.org>
721 * read.c (record_files): Don't set deps flags if there are no deps.
722 * maintMakefile: We only need to build the templates when we are
723 creating a distribution, so don't do it for "all".
725 2005-10-24 Paul D. Smith <psmith@gnu.org>
727 Make secondary expansion optional: its enabled by declaring the
728 special target .SECONDEXPANSION.
730 * NEWS: Update information on second expansion capabilities.
731 * doc/make.texi (Secondary Expansion): Document the
732 .SECONDEXPANSION special target and its behavior.
733 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
734 prerequisite list was found in a static pattern rule.
735 (free_dep_chain): Declare a prototype.
736 * file.c (parse_prereqs): New function: break out some complexity
737 from expand_deps().
738 (expand_deps): If we aren't doing second expansion, replace % with
739 the stem for static pattern rules. Call the new function.
740 * filedef.h (parse_prereqs): Declare a prototype.
741 * implicit.c (pattern_search): Initialize the new staticpattern
742 field.
743 * main.c (second_expansion): Declare a global variable to remember
744 if the special target has been seen. Initialize the new
745 staticpattern field for prerequisites.
746 * make.h: Extern for second_expansion.
747 * misc.c (free_dep_chain): New function: frees a struct dep list.
748 * read.c (read_all_makefiles): Initialize the staticpattern field.
749 (eval_makefile): Ditto.
750 (record_files): Check for the .SECONDEXPANSION target and set
751 second_expansion global if it's found.
752 Use the new free_dep_chain() instead of doing it by hand.
753 Set the staticpattern field for prereqs of static pattern targets.
755 2005-10-16 Paul D. Smith <psmith@gnu.org>
757 * main.c (main): Set CURDIR to be a file variable instead of a
758 default, so that values of CURDIR inherited from the environment
759 won't override the make value.
761 2005-09-26 Paul D. Smith <psmith@gnu.org>
763 * job.c (construct_command_argv_internal): If the line is empty
764 remember to free the temporary argv strings.
765 Fixes bug # 14527.
767 2005-09-16 Paul D. Smith <psmith@gnu.org>
769 * job.c (start_job_command): The noerror flag is a boolean (single
770 bit); set it appropriately.
771 Reported by Mark Eichin <eichin@metacarta.com>
773 2005-08-29 Paul D. Smith <psmith@gnu.org>
775 * function.c (func_error): On Windows, output from $(info ...)
776 seems to come in the wrong order. Try to force it with fflush().
778 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
780 * read.c (record_files): Move code that sets stem for static
781 pattern rules out of the if (!two_colon) condition so it is
782 also executed for two-colon rules. Fixes Savannah bug #13881.
784 2005-08-08 Paul D. Smith <psmith@gnu.org>
786 * make.h: Don't test that __STDC__ is non-0. Some compilers
787 (Windows for example) set it to 0 to denote "ISO C + extensions".
788 Fixes bug # 13594.
790 2005-08-07 Paul D. Smith <psmith@gnu.org>
792 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
793 conditional (slightly different version of a fix from Eli).
795 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
796 If make is running in parallel without -k and two jobs die in a
797 row, but not too close to each other, then make will quit without
798 waiting for the rest of the jobs to die.
800 * main.c (die): Don't reset err before calling reap_children() the
801 second time: we still want it to be in the error condition.
802 * job.c (reap_children): Use a static variable, rather than err,
803 to control whether or not the error message should be printed.
805 2005-08-06 Eli Zaretskii <eliz@gnu.org>
807 * w32/subproc/sub_proc.c: Include signal.h.
808 (process_pipe_io, process_file_io): Pass a pointer to a local
809 DWORD variable to GetExitCodeProcess. If the exit code is
810 CONTROL_C_EXIT, put SIGINT into pproc->signal.
812 * job.c [WINDOWS32]: Include windows.h.
813 (main_thread) [WINDOWS32]: New global variable.
814 (reap_children) [WINDOWS32]: Get the handle for the main thread
815 and store it in main_thread.
817 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
818 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
819 doing anything else. When we are done, close the main thread
820 handle and exit with status 130.
822 2005-07-30 Eli Zaretskii <eliz@gnu.org>
824 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
825 pointer to fprintf.
827 * main.c (find_and_set_default_shell): If found a DOSish shell,
828 set sh_found and the value of default_shell, and report the
829 findings in debug mode.
831 * job.c (construct_command_argv_internal): Check unixy_shell, not
832 no_default_sh_exe, to decide whether to use Unixy or DOSish
833 builtin commands.
835 * README.W32: Update with info about the MinGW build.
837 * build_w32.bat: Support MinGW.
839 * w32/subproc/build.bat: Likewise.
841 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
842 printing DWORD args.
844 * function.c (windows32_openpipe): Fix format strings for printing
845 DWORD args.
847 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
848 'reap_mode'.
849 (start_job_command): Fix format string for printing the result of
850 process_easy.
851 (start_job_command) [WINDOWS32]: Do not define.
852 (exec_command): Fix format string for printing HANDLE args.
854 * main.c (handle_runtime_exceptions): Fix sprintf format strings
855 to avoid compiler warnings.
856 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
857 (Note: some of these fixes were submitted independently by J. Grant)
859 2005-07-30 J. Grant <jg@jguk.org>
861 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
862 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
863 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
865 2005-07-15 Paul Smith <psmith@gnu.org>
867 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
868 we don't have a POSIX shell, then revert to the old
869 backslash-newline behavior (where they are stripped).
870 Fixes bug #13665.
872 2005-07-08 Paul D. Smith <psmith@gnu.org>
874 * config.h.W32.template: Reorder to match the standard config.h,
875 for easier comparisons.
876 From J. Grant <jg@jguk.org>
878 * maintMakefile: Remove .dep_segment before overwriting it, in
879 case it's not writable or noclobber is set.
880 * expand.c (variable_expand_string): Cast result of pointer
881 arithmetic to avoid a warning.
882 * main.c (switches): Add full-fledged final initializer.
884 2005-07-06 Paul D. Smith <psmith@gnu.org>
886 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
887 * signame.c (strsignal): If we found _sys_siglist[] or
888 __sys_siglist[] use those instead of sys_siglist[].
889 From Albert Chin <china@thewrittenword.com>
891 2005-07-04 Paul D. Smith <psmith@gnu.org>
893 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
894 globfree(); set up to use the GNU versions.
895 From Martin Zinser <zinser@zinser.no-ip.info>
897 2005-07-03 Paul D. Smith <psmith@gnu.org>
899 From J. Grant <jg@jguk.org>:
901 * README.W32.template: Update the Windows and tested MSVC versions.
902 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
903 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
904 * build_w32.bat: Ditto.
905 * w32/subproc/build.bat: Ditto.
907 2005-06-28 Paul D. Smith <psmith@gnu.org>
909 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
910 declaration was checked but not present.
912 2005-06-27 Paul D. Smith <psmith@gnu.org>
914 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
915 to unsigned long. Fixes Savannah bug #13550.
917 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
918 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
919 Fixes Savannah bug #13551.
921 2005-06-26 Paul D. Smith <psmith@gnu.org>
923 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
924 it if ANSI_STRING is not set.
926 2005-06-25 Paul D. Smith <psmith@gnu.org>
928 * read.c (eval): If no filenames are passed to any of the
929 "include" variants, don't print an error.
930 * doc/make.texi (Include): Document this.
931 Fixes Savannah bug #1761.
933 * job.c (construct_command_argv_internal): Sanitize handling of
934 backslash/newline pairs according to POSIX: that is, keep the
935 backslash-newline in the command script, but remove a following
936 TAB character, if present. In the fast path, make sure that the
937 behavior matches what the shell would do both inside and outside
938 of quotes. In the slow path, quote the backslash and put a
939 literal newline in the string.
940 Fixes Savannah bug #1332.
941 * doc/make.texi (Execution): Document the new behavior and give
942 some examples.
943 * NEWS: Make a note of the new behavior.
945 * make.h [WINDOWS32]: #include <direct.h>.
946 Fixes Savannah bug #13478.
948 * remake.c (name_mtime): If the stat() of a file fails and the -L
949 option was given and the file is a symlink, take the best mtime of
950 the symlink we can get as the mtime of the file and don't fail.
951 Fixes Savannah bug #13280.
953 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
954 If it's set, then don't stop on STOPCHARs or BLANKs if they're
955 inside a variable reference. Make this function static as it's
956 only used here.
957 (eval): Call find_char_unquote() with IGNOREVARS set when we're
958 parsing an unexpanded line looking for semicolons.
959 Fixes Savannah bug #1454.
960 * misc.c (remove_comments): Move this to read.c and make it static
961 as it's only used there. Call find_char_unquote() with new arg.
962 * make.h: Remove prototypes for find_char_unquote() and
963 remove_comments() since they're static now.
965 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
966 its export flag and obtain its value. When we need to re-exec,
967 increment the value and add it into the environment.
968 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
969 * NEWS: Mention MAKE_RESTARTS.
970 * main.c (always_make_set): New variable. Change the -B option to
971 set this one instead.
972 (main): When checking makefiles, only set always_make_flag if
973 always_make_set is set AND the restarts flag is 0. When building
974 normal targets, set it IFF always_make_set is set.
975 (main): Avoid infinite recursion with -W, too: only set what-if
976 files to NEW before we check makefiles if we've never restarted
977 before. If we have restarted, set what-if files to NEW _after_ we
978 check makefiles.
979 Fixes Savannah bug #7566:
981 2005-06-17 Paul D. Smith <psmith@gnu.org>
983 * default.c: Change VMS implicit rules to use $$$$ instead of $$
984 in the prerequisites list.
986 2005-06-12 Paul D. Smith <psmith@gnu.org>
988 Fix Savannah bug # 1328.
990 * configure.in: Check for atexit().
991 * misc.c (close_stdout): Test stdout to see if writes to it have
992 failed. If so, be sure to exit with a non-0 error code. Based on
993 code found in gnulib.
994 * make.h: Prototype.
995 * main.c (main): Install close_stdout() with atexit().
997 2005-06-10 Paul D. Smith <psmith@gnu.org>
999 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1001 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1002 headers; make vmsWaitForChildren() static; extern vmsify().
1003 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1004 Don't create child_execute_job() here (it's in vmsjobs.c).
1005 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1007 2005-06-09 Paul D. Smith <psmith@gnu.org>
1009 * variable.c (push_new_variable_scope): File variables point
1010 directly to the global_setlist variable. So, inserting a new
1011 scope in front of that has no effect on those variables: they
1012 don't go through current_variable_set_list. If we're pushing a
1013 scope and the current scope is global, push it "the other way" so
1014 that the new setlist is in the global_setlist variable, and
1015 next points to a new setlist with the global variable set.
1016 (pop_variable_scope): Properly undo a push with the new
1017 semantics.
1018 Fixes Savannah bug #11913.
1020 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1022 * job.c (reap_children): Don't die of the command failed but
1023 the dontcare flag is set. Fixes Savannah bug #13216.
1025 * implicit.c (pattern_search): When creating a target from
1026 an implicit rule match, lookup pattern target and set precious
1027 flag in a newly created target. Fixes Savannah bug #13218.
1029 2005-05-13 Paul D. Smith <psmith@gnu.org>
1031 Implement "if... else if... endif" syntax.
1033 * read.c (eval): Push all checks for conditional words ("ifeq",
1034 "else", etc.) down into the conditional_line() function.
1035 (conditional_line): Rework to allow "else if..." clause. New
1036 return value -2 for lines which are not conditionals. The
1037 ignoring flag can now also be 2, which means "already parsed a
1038 true branch". If that value is seen no other branch of this
1039 conditional can be considered true. In the else parsing if there
1040 is extra text after the else, invoke conditional_line()
1041 recursively to see if it's another conditional. If not, it's an
1042 error. If so, raise the conditional value to this level instead
1043 of creating a new conditional nesting level. Special check for
1044 "else" and "endif", which aren't allowed on the "else" line.
1045 * doc/make.texi (Conditional Syntax): Document the new syntax.
1047 2005-05-09 Paul D. Smith <psmith@gnu.org>
1049 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1050 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1051 recurses to the w32 directory, even on non-Windows systems. Use
1052 the method suggested in the automake manual.
1053 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1054 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1056 2005-05-07 Paul D. Smith <psmith@gnu.org>
1058 * main.c (die): If we're dying with a fatal error (not that a
1059 command has failed), write back any leftover tokens before we go.
1061 * job.c (set_child_handler_action_flags): If there are jobs
1062 waiting for the load to go down, set an alarm to go off in 1
1063 second. This allows us to wake up from a potentially long-lasting
1064 read() and start a new job if the load has gone down. Turn it off
1065 after the read.
1066 (job_noop): Dummy signal handler function.
1067 (new_job): Invoke it with the new semantics.
1069 * docs/make.texi: Document secondary expansion. Various cleanups
1070 and random work.
1072 2005-05-03 Paul D. Smith <psmith@gnu.org>
1074 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1075 the targets which are to ultimately be made are called "goals";
1076 see the GNU make manual. Also, MAKECMDGOALS, etc.
1078 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1079 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1080 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1082 2005-05-02 Paul D. Smith <psmith@gnu.org>
1084 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1085 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1086 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1087 functions to vmsjobs.c. #include it into jobs.c.
1089 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1090 jobserver tokens. I found that this happens when an exported
1091 recursive variable contains a $(shell ...) function reference: in
1092 this situation we could "forget" to write back a token.
1094 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1095 we have. It's not reliable to depend on the number of children in
1096 our linked list so keep a separate count.
1097 (new_job): Check jobserver_tokens rather than children &&
1098 waiting_jobs. Increment jobserver_tokens when we get one.
1099 (free_child): If jobserver_tokens is 0, internal error. If it's
1100 >1, write a token back to the jobserver pipe (we don't write a
1101 token for the "free" job). Decrement jobserver_tokens.
1103 * main.c: Add variable master_job_slots.
1104 (main): Set it to hold the number of jobs requested if we're the
1105 master process, when using the jobserver.
1106 (die): Sanity checks: first test jobserver_tokens to make sure
1107 this process isn't holding any tokens we didn't write back.
1108 Second, if master_job_slots is set count the tokens left in the
1109 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1111 2005-04-24 Paul D. Smith <psmith@gnu.org>
1113 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1114 with -l# can lose jobserver tokens, because waiting jobs are not
1115 consulted properly when checking for the "free" token.
1117 * job.c (free_child): Count waiting_jobs as having tokens.
1118 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1119 handle jobs waiting for the load to drop.
1121 2005-04-23 Paul D. Smith <psmith@gnu.org>
1123 * main.c (main): Be careful to not core if a variable setting in
1124 the environment doesn't contain an '='. This is illegal but can
1125 happen in broken setups.
1126 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1128 2005-04-12 Paul D. Smith <psmith@gnu.org>
1130 The second expansion feature causes significant slowdown. Timing
1131 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1132 read the makefile before the feature, to 11+s to do the same
1133 operations after the feature. Additionally, memory usage
1134 increased drastically. To fix this I added some intelligence that
1135 avoids the overhead of the second expansion unless it's required.
1137 * dep.h: Add a new boolean field, need_2nd_expansion.
1139 * read.c (eval): When creating the struct dep for the target,
1140 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1141 (record_files): If there's a "%" in a static pattern rule, it gets
1142 converted to "$*" so set need_2nd_expansion to 1.
1144 * file.c (expand_deps): Rework to be more efficient. Only perform
1145 initialize_file_variables(), set_file_variables(), and
1146 variable_expand_for_file() if the need_2nd_expansion is set.
1148 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1149 (pattern_search): Ditto.
1150 * main.c (handle_non_switch_argument): Ditto.
1151 (main): Ditto.
1152 * read.c (read_all_makefiles): Ditto.
1153 (eval_makefile): Ditto.
1155 2005-04-07 Paul D. Smith <psmith@gnu.org>
1157 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1158 * variable.c (sync_Path_environment): Ditto.
1159 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1161 * main.c (main): Define the .FEATURES variable.
1162 * NEWS: Announce .FEATURES.
1163 * doc/make.texi (Special Variables): Document .FEATURES.
1165 * remake.c (check_dep): If a file is .PHONY, update it even if
1166 it's marked intermediate. Fixes Savannah bug #12331.
1168 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1170 * file.c (expand_deps): Factor out the second expansion and
1171 prerequisite line parsing logic from snap_deps().
1173 * file.c (snap_deps): Use expand_deps(). Expand and parse
1174 prerequisites of the .SUFFIXES special target first. Fixes
1175 Savannah bug #12320.
1177 2005-03-13 Paul D. Smith <psmith@gnu.org>
1179 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1180 Zaretskii.
1182 2005-03-11 Paul D. Smith <psmith@gnu.org>
1184 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1185 available, not undefined (from Earnie Boyd).
1187 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1189 * implicit.c (pattern_search): Mark an intermediate target as
1190 precious if it happened to be a prerequisite of some (other)
1191 target. Fixes Savannah bug #12267.
1193 2005-03-09 Paul D. Smith <psmith@gnu.org>
1195 * read.c (eval_makefile): Add alloca(0).
1196 (eval_buffer): Ditto.
1198 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1200 * main.c (main): Use o_file instead of o_default when defining
1201 the .DEFAULT_TARGET special variable.
1202 * read.c (eval): Use define_variable_global() instead of
1203 define_variable() when setting new value for the .DEFAULT_TARGET
1204 special variable. Fixes Savannah bug #12266.
1206 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1208 * imlicit.c (pattern_search): Mark files for which an implicit
1209 rule has been found as targets. Fixes Savannah bug #12202.
1211 2005-03-04 Paul D. Smith <psmith@gnu.org>
1213 * AUTHORS: Update.
1214 * doc/make.texi (Automatic Variables): Document $|.
1216 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1218 * read.c (record_files): Instead of substituting % with
1219 actual stem value in dependency list replace it with $*.
1220 This fixes stem triple expansion bug.
1222 * implicit.c (pattern_search): Copy stem to a separate
1223 buffer and make it a properly terminated string. Assign
1224 this buffer instead of STEM (which is not terminated) to
1225 f->stem. Instead of substituting % with actual stem value
1226 in dependency list replace it with $*. This fixes stem
1227 triple expansion bug.
1229 2005-03-01 Paul D. Smith <psmith@gnu.org>
1231 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1232 on Windows, as it takes a handle not a pid. Just exit.
1233 Fix from patch #3679, provided by Alessandro Vesely.
1235 * configure.in: Update check for sys_siglist[] from autoconf manual.
1236 * signame.c (strsignal): Update to use the new autoconf macro.
1238 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1240 * read.c (record_files): Add a check for the list of prerequisites
1241 of a static pattern rule being empty. Fixes Savannah bug #12180.
1243 2005-02-28 Paul D. Smith <psmith@gnu.org>
1245 * doc/make.texi (Text Functions): Update docs to allow the end
1246 ordinal for $(wordlist ...) to be 0.
1247 * function.c (func_wordlist): Fail if the start ordinal for
1248 $(wordlist ...) is <1. Matches documentation.
1249 Resolves Savannah support request #103195.
1251 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1252 previously we were stopping when !-q, exactly the opposite. This
1253 has been wrong since version 1.34, in 1994!
1254 (update_file): If we got an error don't break out to run more
1255 double-colon rules: just return immediately.
1256 Fixes Savannah bug #7144.
1258 2005-02-27 Paul D. Smith <psmith@gnu.org>
1260 * misc.c (end_of_token): Make argument const.
1261 * make.h: Update prototype.
1263 * function.c (abspath, func_realpath, func_abspath): Use
1264 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1265 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1266 * read.c (record_files): Ditto.
1267 * variable.c (do_variable_definition): Ditto.
1269 * function.c (func_error): Create a new function $(info ...) that
1270 simply prints the message to stdout with no extras.
1271 (function_table_init): Add new function to the table.
1272 * NEWS: Add $(info ...) reference.
1273 * doc/make.texi (Make Control Functions): Document it.
1275 New feature: if the system supports symbolic links, and the user
1276 provides the -L/--check-symlink-time flag, then use the latest
1277 mtime between the symlink(s) and the target file.
1279 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1280 readlink(). If both are available, define MAKE_SYMLINKS.
1281 * main.c: New variable: check_symlink_flag.
1282 (usage): Add a line for -L/--check-symlink-times to the help string.
1283 (switches): Add -L/--check-symlink-times command line argument.
1284 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1285 print a warning and disable it again.
1286 * make.h: Declare check_symlink_flag.
1287 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1288 if the file is a symlink then check each link in the chain and
1289 choose the NEWEST mtime we find as the mtime for the file. The
1290 newest mtime might be the file itself!
1291 * NEWS: Add information about this new feature.
1292 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1294 Avoid core dumps described in Savannah bug # 12124:
1296 * file.c: New variable snapped_deps remember whether we've run
1297 snap_deps().
1298 (snap_deps): Set it.
1299 * filedef.h: Extern it.
1300 * read.c (record_files): Check snapped_deps; if it's set then
1301 we're trying to eval a new target/prerequisite relationship from
1302 within a command script, which we don't support. Fatal.
1304 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1306 Implementation of the .DEFAULT_TARGET special variable.
1308 * read.c (eval): If necessary, update default_target_name when
1309 reading rules.
1310 * read.c (record_files): Update default_target_file if
1311 default_target_name has changed.
1312 * main.c (default_target_name): Define.
1313 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1314 default_target_name is set use default_target_file as a root
1315 target to make.
1316 * filedef.h (default_target_name): Declare.
1317 * dep.h (free_dep_chain):
1318 * misc.c (free_dep_chain): Change to operate on struct nameseq
1319 and change name to free_ns_chain.
1320 * file.c (snap_deps): Update to use free_ns_chain.
1322 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1324 Implementation of the second expansion in explicit rules,
1325 static pattern rules and implicit rules.
1327 * read.c (eval): Refrain from chopping up rule's dependencies.
1328 Store them in a struct dep as a single dependency line. Remove
1329 the code that implements SySV-style automatic variables.
1331 * read.c (record_files): Adjust the code that handles static
1332 pattern rules to expand all percents instead of only the first
1333 one. Reverse the order in which dependencies are stored so that
1334 when the second expansion reverses them again they appear in
1335 the makefile order (with some exceptions, see comments in
1336 the code). Remove the code that implements SySV-style automatic
1337 variables.
1339 * file.c (snap_deps): Implement the second expansion and chopping
1340 of dependency lines for explicit rules.
1342 * implicit.c (struct idep): Define an auxiliary data type to hold
1343 implicit rule's dependencies after stem substitution and
1344 expansion.
1346 * implicit.c (free_idep_chain): Implement.
1348 * implicit.c (get_next_word): Implement helper function for
1349 parsing implicit rule's dependency lines into words taking
1350 into account variable expansion requests. Used in the stem
1351 splitting code.
1353 * implicit.c (pattern_search): Implement the second expansion
1354 for implicit rules. Also fixes bug #12091.
1356 * commands.h (set_file_variables): Declare.
1357 * commands.c (set_file_variables): Remove static specifier.
1359 * dep.h (free_dep_chain): Declare.
1360 * misc.c (free_dep_chain): Implement.
1362 * variable.h (variable_expand_for_file): Declare.
1363 * expand.c (variable_expand_for_file): Remove static specifier.
1365 * make.h (strip_whitespace): Declare.
1366 * function.c (strip_whitespace): Remove static specifier.
1368 2005-02-26 Paul D. Smith <psmith@gnu.org>
1370 * main.c (main): Check for ferror() when reading makefiles from stdin.
1371 Apparently some shells in Windows don't close pipes properly and
1372 require this check.
1374 2005-02-24 Jonathan Grant <jg@jguk.org>
1376 * configure.in: Add MinGW configuration options, and extra w32 code
1377 directory.
1378 * Makefile.am: Add MinGW configuration options, and extra w32 code
1379 directory.
1380 * main.c: Determine correct program string (after last \ without .exe).
1381 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1382 type fix x2
1383 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1384 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1385 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1386 environment support.
1388 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1390 * function.c (func_shell): When initializing error_prefix, check
1391 that reading file name is not null. This fixes long-standing
1392 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1394 2005-02-09 Paul D. Smith <psmith@gnu.org>
1396 * maintMakefile: Update the CVS download URL to simplify them.
1397 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1398 downloading the .texi files from Savannah now.
1400 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1402 * main.c (handle_non_switch_argument): Only add variables to
1403 command_variables if they're not already there: duplicate settings
1404 waste space and can be confusing to read.
1406 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1407 this header is never included by non-WINDOWS32 code, and it
1408 requires <config.h> to define which isn't always included first.
1410 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1411 testing MINGW32 versions.
1413 * main.c (log_working_directory): flush stdout to be sure the WD
1414 change is printed before any stderr messages show up.
1416 2005-02-01 Paul D. Smith <psmith@gnu.org>
1418 * maintMakefile (po_repo): Update the GNU translation site URL.
1420 2004-12-01 Paul D. Smith <psmith@gnu.org>
1422 * main.c (main): Change char* env_shell to struct variable shell_var.
1423 * variable.c (target_environment): Use new shell_var.
1425 2004-11-30 Paul D. Smith <psmith@gnu.org>
1427 * configure.in: The old way we avoided creating build.sh from
1428 build.sh.in before build.sh.in exists doesn't work anymore; we
1429 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1430 the help!). This also keeps automake from complaining.
1431 * Makefile.am (README): Add a dummy target so automake won't
1432 complain that this file doesn't exist when we checkout from CVS.
1433 * maintMakefile (.dep_segment): Rewrite this rule since newer
1434 versions of automake don't provide DEP_FILES.
1436 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1438 Implementation of `realpath' and `abspath' built-in functions.
1440 * configure.in: Check for realpath.
1441 * function.c (abspath): Return an absolute file name that does
1442 not contain any `.' or `..' components, nor repeated `/'.
1443 * function.c (func_abspath): For each name call abspath.
1444 * function.c (func_realpath): For each name call realpath
1445 from libc or delegate to abspath if realpath is not available.
1446 * doc/make.texi (Functions for File Names): Document new functions.
1447 * doc/make.texi (Quick Reference): Ditto.
1449 2004-11-28 Paul D. Smith <psmith@gnu.org>
1451 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1452 arguments. Fixes bug #10252.
1454 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1456 * main.c (main): Set SHELL to v_noexport by default. Remember the
1457 original environment setting of SHELL in the env_shell variable.
1458 * main.h: Export new env_shell variable.
1459 * variable.c (target_environment): If we find a v_noexport
1460 variable for SHELL, add a SHELL variable with the env_shell value.
1461 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1462 * doc/make.texi (Variables/Recursion): Ditto.
1464 2004-11-28 Paul D. Smith <psmith@gnu.org>
1466 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1467 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1468 Patch by Alessandro Vesely.
1470 2004-11-12 Paul D. Smith <psmith@gnu.org>
1472 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1473 the command line if it's inside a string.
1474 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1476 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1478 * function.c (func_lastword): New function: return last word
1479 from the list of words.
1480 * doc/make.texi: Document $(lastword ). Fix broken links in
1481 Quick Reference section.
1483 2004-10-06 Paul D. Smith <psmith@gnu.org>
1485 Apply patch from Alessandro Vesely, provided with bug # 9748.
1486 Fix use of tmpnam() to work with Borland C.
1488 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1489 construction of a temporary filename, and call new function
1490 create_batch_filename().
1491 (create_batch_filename) [WINDOWS32]: New function to create a
1492 temporary filename.
1494 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1496 * read.c (record_target_var): Expand simple pattern-specific
1497 variable.
1498 * variable.c (initialize_file_variables): Do not expand simple
1499 pattern-specific variable.
1501 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1503 * remake.c (update_file_1): When rebuilding makefiles inherit
1504 dontcare flag from a target that triggered update.
1506 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1508 * variable.c (initialize_file_variables): Mark pattern-specific
1509 variable as a per-target and copy export status.
1511 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1513 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1515 * implicit.c (pattern_search): When considering an implicit rule's
1516 prerequisite check that it is actually a target rather then
1517 just an entry in the file hashtable.
1519 2004-09-21 Paul D. Smith <psmith@gnu.org>
1521 * read.c (readstring): Fix some logic errors in backslash handling.
1522 (eval): Remove some unnecessary processing in buffer handling.
1523 (record_target_var): Assert that parse_variable_definition() succeeded.
1524 Reported by: Markus Mauhart <qwe123@chello.at>.
1526 * misc.c: Removed the sindex() function. All instances of this
1527 function were trivially replaceable by the standard strstr()
1528 function, and that function will always have better (or certainly
1529 no worse) performance than the very simple-minded algorithm
1530 sindex() used. This can matter with complex makefiles.
1531 * make.h: Remove the prototype for sindex().
1532 * function.c (subst_expand): Convert sindex() call to strstr().
1533 This means we no longer need to track the TLEN value so remove that.
1534 (func_findstring): Convert sindex() to strstr().
1535 * commands.c (chop_commands): Convert sindex() calls to strstr().
1536 Suggested by: Markus Mauhart <qwe123@chello.at>.
1538 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1539 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1540 If SHELL is set to CMD.EXE then assume it's batch-mode and
1541 non-unixy. I wrote the code differently from the patch, though,
1542 to make it safer. This also resolves bug #9174.
1544 2004-09-20 Paul D. Smith <psmith@gnu.org>
1546 * expand.c (variable_expand_string): Modify to invoke
1547 patsubst_expand() instead of subst_expand(); the latter didn't
1548 handle suffix patterns correctly.
1549 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1550 was used only from variable_expand_string() and is no longer used
1551 there.
1552 (func_subst): Ditto, on call to subst_expand().
1553 (patsubst_expand): Require the percent pointers to point to the
1554 character after the %, not to the % itself.
1555 * read.c (record_files): New call criteria for patsubst_expand().
1556 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1557 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1559 2004-09-19 Paul D. Smith <psmith@gnu.org>
1561 * function.c (subst_expand): Fix a check in by_word: look for a
1562 previous blank if we're beyond the beginning of the string, not
1563 the beginning of the word.
1564 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1566 2004-05-16 Paul D. Smith <psmith@gnu.org>
1568 * remake.c (update_goal_chain): Change the argument specifying
1569 whether we're rebuilding makefiles to be a global variable,
1570 REBUILDING_MAKEFILES.
1571 (complain): Extract the code that complains about no rules to make
1572 a target into a separate function.
1573 (update_file_1): If we tried to rebuild a file during the makefile
1574 rebuild phase and it was dontcare, then no message was printed.
1575 If we then try to build the same file during the normal build,
1576 print a message this time.
1577 (remake_file): Don't complain about un-remake-able files when
1578 we're rebuilding makefiles.
1580 2004-05-11 Paul D. Smith <psmith@gnu.org>
1582 * job.c (construct_command_argv_internal): OS/2 patches from
1583 Andreas Buening <andreas.buening@nexgo.de>.
1585 2004-05-10 Paul D. Smith <psmith@gnu.org>
1587 * remake.c (update_file): Don't walk the double-colon chain unless
1588 this is a double-colon rule. Fix suggested by Boris Kolpackov
1589 <boris@kolpackov.net>.
1591 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1592 * readme.vms: New section describing OpenVMS support and issues.
1593 * default.c (default_variables): Add support for IA64.
1594 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1595 without some privilege aborts make with the error
1596 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1597 pressing Ctrl+Y and the input device is no terminal. The change
1598 catches this error and just continues.
1600 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1602 2004-04-25 Paul D. Smith <psmith@gnu.org>
1604 * commands.c (set_file_variables): Set $< properly in the face of
1605 order-only prerequisites.
1606 Patch from Boris Kolpackov <boris@kolpackov.net>
1608 2004-04-21 Bob Byrnes <byrnes@curl.com>
1610 * main.c (main): Notice failures to remake makefiles.
1612 2004-03-28 Paul D. Smith <psmith@gnu.org>
1614 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1616 * job.c: No default shell for RISC OS.
1617 (load_too_high): Hard-code the return to 1.
1618 (construct_command_argv_internal): No sh_chars or sh_cmds.
1619 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1621 2004-03-20 Paul D. Smith <psmith@gnu.org>
1623 * variable.c (do_variable_definition): Don't append from the
1624 global set if a previous non-appending target-specific variable
1625 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1626 (with fix).
1628 * expand.c (reference_variable): Don't give up on variables with
1629 no value that have the target-specific append flag set: they might
1630 have a value after all. Reported by Oliver Schmidt
1631 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1632 <nikulin@dx1cmd.inp.nsk.su>.
1634 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1635 refer to absolute pathnames in directories that don't exist: some
1636 portion of the makefile could create those directories before we
1637 match the pattern. Fixes bugs #775 and #108.
1639 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1641 * main.c (main): Free makefile_mtimes if we have any.
1642 * README.W32.template: Update documentation for the current status
1643 of the MS-Windows port.
1644 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1645 environment variable is sometimes already defined which causes the
1646 build to fail.
1647 * main.c (debug_signal_handler): Only define this function if
1648 SIGUSR1 is available.
1650 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1652 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1653 * README.OS2.template: Documentation updates.
1654 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1655 link line for safety.
1656 * maintMakefile (build.sh.in): Remove an extraneous ")".
1657 * job.c (child_execute_job): Close saved FDs.
1658 * job.c (exec_command) [OS/2]: exec_command(): If the command
1659 can't be exec'ed and if the shell is not Unix-sh, then try again
1660 with argv = { "cmd", "/c", ... }. Normally, this code is never
1661 reached for the cmd shell unless the command really doesn't exist.
1662 (construct_command_argv_internal) [OS/2]: The code for cmd
1663 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1664 The CMD builtin commands are case insensitive so use strcasecmp().
1666 2004-03-19 Paul D. Smith <psmith@gnu.org>
1668 * read.c (do_define): Re-order line counter increment so the count
1669 is accurate (we were losing one line per define). Reported by
1670 Dave Yost <Dave@Yost.com>.
1672 2004-03-06 Paul D. Smith <psmith@gnu.org>
1674 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1675 compiler.
1676 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1677 * misc.c (message,error,fatal): Ditto.
1678 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1679 * config.h.W32.template: Ditto.
1680 * config.h-vms.template: Ditto.
1681 * config.ami.template: Ditto.
1683 2004-03-04 Paul D. Smith <psmith@gnu.org>
1685 * README.template: Add a note about broken /bin/sh on SunOS
1686 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1688 * misc.c (message, error, fatal): Don't use "..." if we're using
1689 varargs. ansi2knr should handle this but it doesn't work: it
1690 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1691 done. On many systems (SunOS for example) va_dcl is a #define.
1692 So, force the use of the non-"..." version on pre-ANSI compilers.
1694 * maintMakefile (sign-dist): Create some rules to help automate
1695 the new GNU ftp upload method.
1697 2004-02-24 Paul D. Smith <psmith@gnu.org>
1699 * config.h.W32.template: Add HAVE_STDARG_H
1700 * config.h-vms.template: Ditto.
1701 * config.ami.template: Ditto.
1703 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1705 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1706 * build_w32.bat: Remove extra "+".
1708 2004-02-23 Paul D. Smith <psmith@gnu.org>
1710 * make.h: Create an UNUSED macro to mark unused parameters.
1711 * (many): Clean up warnings by applying UNUSED, fixing
1712 signed/unsigned incompatibilities, etc.
1714 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1715 autoconf warnings.
1716 * filedef.h: Name the command_state enumeration.
1717 * file.c (set_command_state): Use the enumeration in the function
1718 argument.
1720 * configure.in: Explicitly set SET_MAKE to empty, to disable
1721 MAKE=make even when no make already exists. Fix bug #3823.
1723 2004-02-22 Paul D. Smith <psmith@gnu.org>
1725 * maintMakefile: Perl script to clean up all non-CVS files. Use
1726 it on all the subdirectories for the cvs-clean target.
1728 * main.c (decode_switches): Require non-empty strings for all our
1729 string command-line options. Fixes Debian bug # 164165.
1731 * configure.in: Check for stdarg.h and varargs.h.
1732 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1733 for printing messages.
1734 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1735 (message): Ditto.
1736 (error): Ditto.
1737 (fatal): Ditto.
1739 A number of patches for OS/2 support from Andreas Buening
1740 <andreas.buening@nexgo.de>:
1742 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1743 disable the SIGCHLD handler.
1744 (reap_children) [OS/2]: Remove special handling of job_rfd.
1745 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1746 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1747 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1748 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1749 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1750 systems.
1752 2004-02-21 Paul D. Smith <psmith@gnu.org>
1754 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1755 <mail@kristov.de> reports that if process_begin() fails we don't
1756 handle the error condition correctly in all cases.
1757 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1758 to have a newline on the message.
1760 * job.c (construct_command_argv_internal): Add "test" to UNIX
1761 sh_cmds[]. Fixes Savannah bug # 7606.
1763 2004-02-04 Paul D. Smith <psmith@gnu.org>
1765 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1766 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1767 Hartmut Becker <Hartmut.Becker@hp.com>.
1769 2004-01-21 Paul D. Smith <psmith@gnu.org>
1771 * job.c (load_too_high): Implement an algorithm to control the
1772 "thundering herd" problem when using -l to control job creation
1773 via the load average. The system only recomputes the load once a
1774 second but we can start many jobs in a second. To solve this we
1775 keep track of the number of jobs started in the last second and
1776 apply a weight to try to guess what a correct load would be.
1777 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1778 Also fixes bug #4693.
1779 (reap_children): Decrease the job count for this second.
1780 (start_job_command): Increase the job count for this second.
1782 * read.c (conditional_line): Expand the text after ifn?def before
1783 checking to see if it's a single word. Fixes bug #7257.
1785 2004-01-09 Paul D. Smith <psmith@gnu.org>
1787 * file.c (print_file): Recurse to print all targets in
1788 double-colon rules. Fixes bug #4518, reported (with patch) by
1789 Andrew Chatham <chatham@google.com>.
1791 2004-01-07 Paul D. Smith <psmith@gnu.org>
1793 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1794 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1795 AC_FUNC_SETVBUF_REVERSED.
1797 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1798 (MAKE Variable): Fix Savannah bug #4898.
1800 * job.c (construct_command_argv_internal): Add "!" to the list of
1801 shell escape chars. POSIX sh allows it to appear before a
1802 command, to negate the exit code. Fixes bug #6404.
1804 * implicit.c (pattern_search): When matching an implicit rule,
1805 remember which dependencies have the ignore_mtime flag set.
1806 Original fix provided in Savannah patch #2349, by Benoit
1807 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1809 2003-11-22 Paul D. Smith <psmith@gnu.org>
1811 * README.W32.template (Outputs): Clarification on -j with
1812 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1813 <jg-make@jguk.org>.
1815 2003-11-02 Paul D. Smith <psmith@gnu.org>
1817 * function.c (func_if): Strip all the trailing whitespace from the
1818 condition, then don't expand it. Fixed bug # 5798.
1820 * expand.c (recursively_expand_for_file): If we're expanding a
1821 variable with no file context, then use the variable's context.
1822 Fixes bug # 6195.
1824 2003-10-21 Paul D. Smith <psmith@gnu.org>
1826 * main.c (log_working_directory): Add newlines to printf()s.
1828 * README.cvs: Add a note to ignore warnings during autoreconf.
1830 * maintMakefile (po_repo): Set a new URL for PO file updates.
1831 (get-config/config.guess get-config/config.sub): Get these files
1832 from the Savannah config project instead of ftp.gnu.org.
1834 2003-10-05 Paul Eggert <eggert@twinsun.com>
1836 * main.c (main): Avoid potential subscript error if environ has
1837 short strings.
1839 2003-08-22 Paul D. Smith <psmith@gnu.org>
1841 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1842 systems which don't yet implement the C89 standard :-/.
1844 2003-07-18 Paul D. Smith <psmith@gnu.org>
1846 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1847 [WINDOWS32]: Initialize hash.
1849 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1851 * dir.c (read_dirstream): Provide a workaround for broken versions of
1852 the MinGW dirent structure.
1854 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1856 * w32/include/dirent.h: Add __MINGW32__ filter.
1858 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1860 * make.h: Add global declaration of *make_host.
1861 * main.c (print_usage): Remove local declaration of *make_host.
1862 (print_version): Display "This program built for ..." after Copyright
1863 notice.
1865 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1867 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1868 execution of "makeinfo --html make.texi".
1870 2003-04-30 Paul D. Smith <psmith@gnu.org>
1872 * build.template: Make some changes to maybe allow this script to
1873 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1875 * README.OS2.template: New file for OS/2 support. Original
1876 contributed by Andreas Buening.
1877 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1878 DOS-style paths.
1880 2003-04-19 Paul D. Smith <psmith@gnu.org>
1882 Fix bug #1405: allow a target to match multiple pattern-specific
1883 variables.
1885 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1886 variable.c, where they've always belonged.
1887 * rule.h: Move the prototypes and struct pattern_var as well.
1888 * variable.c (initialize_file_variables): Invoke
1889 lookup_pattern_var() in a loop, until no more matches are found.
1890 If a match is found, create a new variable set for the target's
1891 pattern variables. Then merge the contents of each matching
1892 pattern variable set into the target's pattern variable set.
1893 (lookup_pattern_var): Change this function to be usable
1894 in a loop. It takes a starting position: if NULL, start at the
1895 beginning; if non-NULL, start with the pattern variable after that
1896 position, and return the next matching pattern.
1897 (create_pattern_var): Create a unique instance of
1898 pattern-specific variables for every definition in the makefile.
1899 Don't combine the same pattern together. This allows us to
1900 process the variable handling properly even when the same pattern
1901 is used multiple times.
1902 (parse_variable_definition): New function: break out the parsing
1903 of a variable definition line from try_variable_definition.
1904 (try_variable_definition): Call parse_variable_definition to
1905 parse.
1906 (print_variable_data_base): Print out pattern-specific variables.
1907 * variable.h (struct variable): Remember when a variable is
1908 conditional. Also remember its flavor.
1909 (struct pattern_var): Instead of keeping a variable set, we just
1910 keep a single variable for each pattern.
1911 * read.c (record_target_var): Each pattern variable contains only a
1912 single variable, not a set, so create it properly.
1913 * doc/make.texi (Pattern-specific): Document the new behavior.
1915 2003-04-17 Paul D. Smith <psmith@gnu.org>
1917 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1918 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1919 file/directory naming rules for VMS so I can't tell whether this
1920 is correct or not.
1922 2003-04-09 Paul D. Smith <psmith@gnu.org>
1924 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1925 DOS-style pathnames: backslash separators and drive specifiers.
1927 2003-03-28 Paul D. Smith <psmith@gnu.org>
1929 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1930 the intermediate flag on all targets. Fixes bug #2515.
1932 2003-03-24 Paul D. Smith <psmith@gnu.org>
1934 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1935 Upgrade to autoconf 2.57 and automake 1.7.3.
1937 * job.c: More OS/2 changes from Andreas Buening.
1939 * file.c (print_file): Fix variable initialization.
1940 Fixes bug #2892.
1942 * remake.c (notice_finished_file):
1944 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1945 some calls (like readdir()) return NULL in valid situations
1946 without resetting errno. Fixes bug #2846.
1948 2003-02-25 Paul D. Smith <psmith@gnu.org>
1950 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1952 * job.c (_is_unixy_shell) [OS/2]: New function.
1953 Set default shell to /bin/sh.
1954 (reap_children): Close the job_rfd pipe here since we don't use a
1955 SIGCHLD handler.
1956 (set_child_handler_action_flags): define this to empty on OS/2.
1957 (start_job_command): Close the jobserver pipe and use
1958 child_execute_job() instead of fork/exec.
1959 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1960 rather than exec'ing, then reconfigure stdin/stdout.
1961 (exec_command): Rewrite to use spawn instead of exec. Return the
1962 PID of the child.
1964 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1965 in DOS. Handle the TEMP environment variable as in DOS. Don't
1966 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1967 use -j in DOS mode. Use child_execute_job() instead of
1968 exec_command().
1970 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1971 spawn() instead.
1973 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1974 prototypes that return values.
1976 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1978 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1979 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1980 for OS/2.
1981 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1982 DOS paths.
1984 2003-02-24 Paul D. Smith <psmith@gnu.org>
1986 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1987 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1988 (child_execute_job) [VMS]: Handle error status properly.
1989 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1991 * function.c (func_shell): Use EINTRLOOP() while reading from the
1992 subshell pipe (Fixes bug #2502).
1993 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1994 jobserver pipe.
1995 * main.c (main): Ditto.
1997 2003-01-30 Paul D. Smith <psmith@gnu.org>
1999 * read.c (eval): eval() was not fully reentrant, because the
2000 collapsed buffer was static. Change it to be an automatic
2001 variable so that eval() can be invoked recursively.
2002 Fixes bug # 2238.
2003 (eval): Apply patch # 1022: fix memory reference error on long
2004 target-specific variable lines.
2005 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2007 * function.c (check_numeric): Combine the is_numeric() function
2008 into this function, since it's only called from one place.
2009 Constify this function. Have it print the incorrect string in the
2010 error message. Fixes bug #2407.
2011 (strip_whitespace): Constify.
2012 (func_if): Constify.
2013 * expand.c (expand_argument): Constify.
2015 2003-01-29 Paul D. Smith <psmith@gnu.org>
2017 Fix bug # 2169, also reported by other people on various systems.
2019 * make.h: Some systems, such as Solaris and PTX, do not fully
2020 implement POSIX-compliant SA_RESTART functionality; important
2021 system calls like stat() and readdir() can still fail with EINTR
2022 even if SA_RESTART has been set on the signal handler. So,
2023 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2024 EINTR for system calls which return -1 or 0 (NULL), respectively,
2025 on error.
2026 Also, remove the old atomic_stat()/atomic_readdir() and
2027 HAVE_BROKEN_RESTART handling.
2029 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2031 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2032 * remake.c (touch_file): Ditto.
2034 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2035 * read.c (construct_include_path): Ditto.
2036 * remake.c (name_mtime): Ditto.
2037 * vpath.c (selective_vpath_search): Ditto.
2038 * dir.c (find_directory): Ditto.
2039 (local_stat): Ditto.
2040 (find_directory): Use ENULLLOOP() to wrap opendir().
2041 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2043 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2044 atomic_readdir() handling.
2046 2003-01-22 Paul D. Smith <psmith@gnu.org>
2048 * function.c (func_call): Fix Bug #1744. If we're inside a
2049 recursive invocation of $(call ...), mask any of the outer
2050 invocation's arguments that aren't used by this one, so that this
2051 invocation doesn't "inherit" them accidentally.
2053 2002-12-05 Paul D. Smith <psmith@gnu.org>
2055 * function.c (subst_expand): Valery Khamenia reported a
2056 pathological performance hit when doing substitutions on very
2057 large values with lots of words: turns out we were invoking
2058 strlen() a ridiculous number of times. Instead of having each
2059 call to sindex() call strlen() again, keep track of how much of
2060 the text we've seen and pass the length to sindex().
2062 2002-11-19 Paul D. Smith <psmith@gnu.org>
2064 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2067 2002-11-16 Paul D. Smith <psmith@gnu.org>
2069 * NMakefile.template (OBJS): Add hash.c object file.
2070 * SMakefile.template (srcs): Ditto.
2071 * Makefile.ami (objs): Ditto.
2072 * build_w32.bat: Ditto.
2074 * Makefile.DOS.template: Remove extra dependencies.
2076 2002-10-25 Paul D. Smith <psmith@gnu.org>
2078 * expand.c (install_variable_buffer): New function. Install a new
2079 variable_buffer context and return the previous one.
2080 (restore_variable_buffer): New function. Free the current
2081 variable_buffer context and put a previously saved one back.
2082 * variable.h: Prototypes for {install,restore}_variable_buffer.
2083 * function.c (func_eval): Push a new variable_buffer context
2084 before we eval, then restore the old one when we're done.
2085 Fixes Bug #1517.
2087 * read.c (install_conditionals): New function. Install a new
2088 conditional context and return the previous one.
2089 (restore_conditionals): New function. Free the current
2090 conditional context and put a previously saved one back.
2091 (eval): Use the {install,restore}_conditionals for "include"
2092 handling.
2093 (eval_buffer): Use {install,restore}_conditionals to preserve the
2094 present conditional state before we evaluate the buffer.
2095 Fixes Bug #1516.
2097 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2098 and $(value ...).
2099 (Recursion): Add a variable index entry for CURDIR.
2101 * README.cvs: Update to appropriate versions.
2102 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2103 don't need to copy loadavg.c: automake is smart enough to create
2104 it for me. Still have a bug in automake related to ansi2knr tho.
2106 2002-10-14 Paul D. Smith <psmith@gnu.org>
2108 * remake.c (notice_finished_file): Only touch targets if they have
2109 at least one command (as per POSIX). Resolve Bug #1418.
2111 * *.c: Convert to using ANSI C-style function definitions.
2112 * Makefile.am: Enable the ansi2knr feature of automake.
2113 * configure.in: ditto.
2115 2002-10-13 Paul D. Smith <psmith@gnu.org>
2117 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2118 for automatic variable values like $^, etc. In the case of very
2119 large lists of prerequisites this causes problems. Instead reuse
2120 a static buffer (resizeable) for each variable.
2122 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2123 target-specific variable definitions. Check for it and set an
2124 "exported" flag.
2125 (record_target_var): Set the export field to v_export if the
2126 "exported" flag is set.
2127 * doc/make.texi (Target-specific): Document the ability to use
2128 "export".
2130 * doc/make.texi: Change the name of the section on automatic
2131 variables from "Automatic" to "Automatic Variables". Added text
2132 clarifying the scope of automatic variables.
2134 2002-10-04 Paul D. Smith <psmith@gnu.org>
2136 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2137 as () braces.
2138 (record_files): Ditto.
2140 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2141 the search for the '=' to only within the enclosing parens.
2143 2002-10-03 Paul D. Smith <psmith@gnu.org>
2145 Version 3.80 released.
2147 * dir.c: Change hash functions to use K&R function definition style.
2148 * function.c: Ditto.
2149 * read.c: Ditto.
2150 * variable.c: Ditto.
2152 Update to automake 1.7.
2154 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2155 (pdf): Remove this target as automake now provides one.
2157 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2159 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2161 * makefile.com: Updates for GNU make 3.80.
2162 * makefile.vms: Ditto.
2164 2002-09-23 Paul D. Smith <psmith@gnu.org>
2166 * read.c (enum make_word_type): Remove w_comment.
2167 (get_next_mword): Don't treat comment characters as special; where
2168 this function is used we will never see a comment (it's stripped
2169 before we get here) and treating comments specially means that
2170 targets like "foo\#bar" aren't handled properly.
2172 2002-09-18 Paul D. Smith <psmith@gnu.org>
2174 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2176 * read.c (eval): Expansion of arguments to export/unexport was
2177 ignoring all arguments after the first one. Change the algorithm
2178 to expand the whole line once, then parse the results.
2180 2002-09-17 Paul D. Smith <psmith@gnu.org>
2182 Fix Bug #940 (plus another bug I found while looking at this):
2184 * read.c (record_target_var): enter_file() will add a new entry if
2185 it's a double-colon target: we don't want to do that in this
2186 situation. Invoke lookup_file() and only enter_file() if it does
2187 not already exist. If the file we get back is a double-colon then
2188 add this variable to the "root" double-colon target.
2190 * variable.c (initialize_file_variables): If this file is a
2191 double-colon target but is not the "root" target, then initialize
2192 the root and make the root's variable list the parent of our
2193 variable list.
2195 2002-09-13 Paul D. Smith <psmith@gnu.org>
2197 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2199 * hash.c (round_up_2): Get rid of a warning.
2201 2002-09-12 Paul D. Smith <psmith@gnu.org>
2203 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2204 so it doesn't complain about getloadavg.c.
2206 * commands.c (set_file_variables): Make sure we always alloca() at
2207 least 1 character for the value of $? (for '\0').
2209 2002-09-11 Paul D. Smith <psmith@gnu.org>
2211 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2212 macro to use RESULT instead of the incorrect _RESULT_.
2214 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2215 and atomic_readdir(). We need to #include dirent.h to get this to
2216 work.
2217 * misc.c (atomic_readdir): Fix typos.
2219 2002-09-10 Paul D. Smith <psmith@gnu.org>
2221 * read.c (eval): Expand variable lists given to export and
2222 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2223 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2225 * doc/make.texi (Variables/Recursion): Document this.
2226 (Conditional Syntax): And here.
2228 2002-09-09 Paul D. Smith <psmith@gnu.org>
2230 * configure.in: Check for memmove().
2232 2002-09-07 Paul D. Smith <psmith@gnu.org>
2234 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2235 Michael Sterrett <msterret@coat.com> reports that while it has
2236 SA_RESTART, it does not work properly.
2238 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2239 that invokes stat() and loops to do it again if it returns EINTR.
2240 (atomic_readdir): Ditto, with readdir().
2242 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2243 and readdir() to atomic_stat() and atomic_readdir().
2245 2002-09-04 Paul D. Smith <psmith@gnu.org>
2247 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2248 reports that GNU make sometimes doesn't recognize that targets can
2249 be made, when directories can be created as prerequisites. He
2250 reports that changing the order of predicates in the DEP->changed
2251 flag test so that lookup_file() is always performed, solves this
2252 problem.
2254 2002-08-08 Paul D. Smith <psmith@gnu.org>
2256 * configure.in: Require a newer version of gettext.
2258 * misc.c (perror_with_name): Translate the format string (for
2259 right-to-left language support).
2260 (pfatal_with_name): Ditto.
2262 * main.c: Create a static array of strings to store the usage
2263 text. This is done to facilitate translations.
2264 (struct command_switch): Remove argdesc and description fields.
2265 (switches): Remove values for obsolete fields.
2266 (print_usage): Print each element of the usage array.
2268 * hash.c: Change function definitions to be K&R style.
2270 2002-08-02 Paul D. Smith <psmith@gnu.org>
2272 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2273 this one because it's too hard to get right. We'll look at it for
2274 a future release.
2275 * main.c (main): Don't create the .TARGETS variable.
2276 * variable.c (handle_special_var): Don't handle .TARGETS.
2278 2002-08-01 Paul D. Smith <psmith@gnu.org>
2280 * main.c (switches): Add a new option, -B (--always-make). If
2281 specified, make will rebuild all targets that it encounters even
2282 if they don't appear to be out of date.
2283 (always_make_flag): New flag.
2284 * make.h: Extern always_make_flag.
2285 * remake.c (update_file_1): Check always_make_flag; if it's set we
2286 will always rebuild any target we can, even if none of its
2287 prerequisites are newer.
2288 * NEWS: Mention it.
2290 * doc/make.texi (Shell Function): Make it clear that make
2291 variables marked as "export" are not passed to instances of the
2292 shell function.
2294 Add new introspection variable .VARIABLES and .TARGETS.
2296 * variable.c (handle_special_var): New function. If the variable
2297 reference passed in is "special" (.VARIABLES or .TARGETS),
2298 calculate the new value if necessary. .VARIABLES is handled here:
2299 walk through the hash of defined variables and construct a value
2300 which is a list of the names. .TARGETS is handled by
2301 build_target_list().
2302 (lookup_variable): Invoke handle_special_var().
2303 * file.c (build_target_list): Walk through the hask of known files
2304 and construct a list of the names of all the ones marked as
2305 targets.
2306 * main.c (main): Initialize them to empty (and as simple variables).
2307 * doc/make.texi (Special Variables): Document them.
2308 * NEWS: Mention them.
2310 * variable.h (struct variable): Add a new flag "exportable" which
2311 is true if the variable name is valid for export.
2312 * variable.c (define_variable_in_set): Set "exportable" when a new
2313 variable is defined.
2314 (target_environment): Use the "exportable" flag instead of
2315 re-checking the name here... an efficiency improvement.
2317 2002-07-31 Paul D. Smith <psmith@gnu.org>
2319 * config.h-vms.template: Updates to build on VMS. Thanks to
2320 Brian_Benning@aksteel.com for helping verify the build.
2321 * makefile.com: Build the new hash.c file.
2322 * hash.h: Use strcpmi(), not stricmp(), in the
2323 HAVE_CASE_INSENSITIVE_FS case.
2325 2002-07-30 Paul D. Smith <psmith@gnu.org>
2327 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2328 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2329 Reported by <Brian_Benning@aksteel.com>.
2331 2002-07-10 Paul D. Smith <psmith@gnu.org>
2333 * variable.c (pop_variable_scope): Remove variable made unused by
2334 new hash infrastructure.
2335 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2336 comparisons as well as name comparisons.
2337 * variable.h: Add a prototype for new hash_init_function_table().
2338 * file.c (lookup_file): Remove variables made unused by new hash
2339 infrastructure.
2340 * dir.c (directory_contents_hash_2): Missing return of hash value.
2341 (dir_contents_file_exists_p): Remove variables made unused by new
2342 hash infrastructure.
2345 Installed Greg McGary's integration of the hash functions from the
2346 GNU id-utils package:
2348 2002-07-10 Greg McGary <greg@mcgary.org>
2350 * scripts/functions/filter-out: Add literals to to the
2351 pattern space in order to add complexity, and trigger
2352 use of an internal hash table. Fix documentation strings.
2353 * scripts/targets/INTERMEDIATE: Reverse order of files
2354 passed to expected `rm' command.
2356 2002-07-10 Greg McGary <greg@mcgary.org>
2358 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
2359 * hash.c: New file, taken from id-utils.
2360 * hash.h: New file, taken from id-utils.

2372 * ar.c (ar_name): Delay call to strlen until needed.
2373 * main.c (initialize_global_hash_tables): New function.
2374 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
2375 * misc.c (remove_comments): Pass char constants to find_char_unquote.
2376 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.

2394 (print_dir_data_base): Likewise.
2395 (open_dirstream): Likewise.
2396 (read_dirstream): Likewise.
2397 (hash_init_directories): New function.
2399 * file.c (hash.h): New #include.
2400 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
2401 (files): Change type to `struct hash_table'.
2402 (lookup_file): Use new hash table package.
2403 (enter_file): Likewise.
2404 (remove_intermediates): Likewise.
2405 (snap_deps): Likewise.
2406 (print_file_data_base): Likewise.
2408 * function.c
2409 (function_table_entry_hash_1, function_table_entry_hash_2,
2410 function_table_entry_hash_cmp): New functions.
2411 (lookup_function): Remove `table' argument.

2415 (struct a_pattern): New struct.
2416 (func_filter_filterout): Pass through patterns noting boundaries
2417 and '%', if present. Note a_word length. Use a hash table if
2418 arglists are large enough to justify cost.
2419 (function_table_init): Renamed from function_table.
2420 (function_table): Declare as `struct hash_table'.
2421 (FUNCTION_TABLE_ENTRIES): New constant.

2424 * read.c (hash.h): New #include.
2425 (read_makefile): Pass char constants to find_char_unquote.
2426 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
2427 (uniquize_deps): Use hash table to efficiently identify duplicates.
2428 (find_char_unquote): Accept two char-constant stop chars, rather
2429 than a string constant, avoiding zillions of calls to strchr.
2430 Tighten inner search loops to test only for desired delimiters.
2432 * variable.c (variable_hash_1, variable_hash_2,
2433 variable_hash_cmp): New functions.
2434 (variable_table): Declare as `struct hash_table'.
2435 (global_variable_set): Remove initialization.

2445 (target_environment): Likewise.
2446 (print_variable_set): Likewise.
2448 2002-07-10 Paul D. Smith <psmith@gnu.org>
2450 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2451 prerequisite list. A real SysV make will expand the entire
2452 prerequisites list _twice_: we don't do that as it's a big
2453 backward-compatibility problem. We only replace those specific
2454 variables.
2456 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2457 references left in the list of prerequisites. Check for .POSIX as
2458 we record targets, so we can disable non-POSIX behavior while
2459 reading makefiles as well as running them.
2460 (eval): Check the prerequisite list to see if we have anything
2461 that looks like a SysV prerequisite variable reference.
2463 2002-07-09 Paul D. Smith <psmith@gnu.org>
2465 * doc/make.texi (Prerequisite Types): Add a new section describing
2466 order-only prerequisites.
2468 * read.c (uniquize_deps): If we have the same file as both a
2469 normal and order-only prereq, get rid of the order-only prereq,
2470 since the normal one supersedes it.
2472 2002-07-08 Paul D. Smith <psmith@gnu.org>
2474 * AUTHORS: Added Greg McGary to the AUTHORS file.
2475 * NEWS: Blurbed order-only prerequisites.
2476 * file.c (print_file): Show order-only deps properly when printing
2477 the database.
2479 * maintMakefile: Add "update" targets for wget'ing the latest
2480 versions of various external files. Taken from Makefile.maint in
2481 autoconf, etc.
2483 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2484 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2486 2002-07-07 Paul D. Smith <psmith@gnu.org>
2488 * po/*.po: Remove. We'll use wget to retrieve them at release
2489 time.
2491 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2492 rather than a shell you get an exception. Make sure we look up
2493 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2495 * remake.c (notice_finished_file): Fix handling of -t flag.
2496 Patch provided by Henning Makholm <henning@makholm.net>.
2498 * implicit.c (pattern_search): Some systems apparently run short
2499 of stack space, and using alloca() in this function caused an
2500 overrun. I modified it to use xmalloc() on the two variables
2501 which seemed like they might get large. Fixes Bug #476.
2503 * main.c (print_version): Update copyright notice to conform with
2504 GNU standards.
2505 (print_usage): Update help output.
2507 * function.c (func_eval): Create a new make function, $(eval
2508 ...). Expand the arguments, put them into a buffer, then invoke
2509 eval_buffer() on the resulting string.
2510 (func_quote): Create a new function, $(quote VARNAME). Inserts
2511 the value of the variable VARNAME without expanding it any
2512 further.
2514 * read.c (struct ebuffer): Change the linebuffer structure to an
2515 "eval buffer", which can be either a file or a buffer.
2516 (eval_makefile): Move the code in the old read_makefile() which
2517 located a makefile into here: create a struct ebuffer with that
2518 information. Have it invoke the new function eval() with that
2519 ebuffer.
2520 (eval_buffer): Create a new function that creates a struct ebuffer
2521 that holds a string buffer instead of a file. Have it invoke
2522 eval() with that ebuffer.
2523 (eval): New function that contains the guts of the old
2524 read_makefile() function: this function parses makefiles. Obtains
2525 data to parse from the provided ebuffer. Some modifications to
2526 make the flow of the function cleaner and clearer. Still could
2527 use some work here...
2528 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2529 contents of the define/endef variable from the ebuffer.
2530 (readstring): Read the next line from a string-style ebuffer.
2531 (readline): Read the next line from an ebuffer. If it's a string
2532 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2533 from the file.
2535 * dep.h (eval_buffer): Prototype eval_buffer();
2537 * variable.c (do_variable_definition): Make sure that all
2538 non-target-specific variables are registered in the global set.
2539 If we're invoked from an $(eval ...) we might be inside a $(call
2540 ...) or other function which has pushed a variable scope; we still
2541 want to define our variables from evaluated makefile code in the
2542 global scope.
2544 2002-07-03 Greg McGary <greg@mcgary.org>
2546 * dep.h (struct dep) [ignore_mtime]: New member.
2547 [changed]: convert to a bitfield.
2548 * implicit.c (pattern_search): Zero ignore_mtime.
2549 * main.c (main, handle_non_switch_argument): Likewise.
2550 * rule.c (convert_suffix_rule): Likewise.
2551 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2552 (read_makefile): Parse '|' in prerequisite list.
2553 (uniquize_deps): Consider ignore_mtime when comparing deps.
2554 * remake.c (update_file_1, check_dep): Don't force remake for
2555 dependencies that have d->ignore_mtime.
2556 * commands.c (FILE_LIST_SEPARATOR): New constant.
2557 (set_file_variables): Don't include a
2558 prerequisite in $+, $^ or $? if d->ignore_mtime.
2559 Define $|.
2561 2002-06-18 Paul D. Smith <psmith@gnu.org>
2563 * make.texinfo: Updates for next revision. New date/rev/etc.
2564 Recreate all Info menus. Change license on the manual to the GNU
2565 Free Documentation License. A number of typos.
2566 (Variables Simplify): Don't use "-" before it's defined.
2567 (Automatic Prerequisites): Rewrite the target example to work
2568 properly if the compile fails. Remove incorrect comments about
2569 how "set -e" behaves.
2570 (Text Functions): Move the "word", "wordlist", "words", and
2571 "firstword" functions here, from "File Name Functions".
2572 * make-stds.texi: Update from latest GNU version.
2573 * fdl.texi: (created) Import the latest GNU version.
2575 2002-06-06 Paul D. Smith <psmith@gnu.org>
2577 * variable.c (do_variable_definition): New function: extract the
2578 part of try_variable_definition() that actually sets the value
2579 into a separate function.
2580 (try_variable_definition): Call do_variable_definition() after
2581 parsing the variable definition string.
2582 (define_variable_in_set): Make the name argument const.
2584 * variable.h (enum variable_flavor): Make public.
2585 (do_variable_definition): Create prototype.
2587 * read.c (read_all_makefiles): Create a new built-in variable,
2588 MAKEFILE_LIST.
2589 (read_makefile): Add each makefile read in to this variable value.
2591 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2593 * Makefile.DOS.template: Tweak according to changes in the
2594 distribution. Add back the dependencies of *.o files.
2596 * configh.dos.template: Synchronize with config.h.in.
2598 2002-05-09 Paul D. Smith <psmith@gnu.org>
2600 * file.c (file_timestamp_now): Use K&R function declaration.
2602 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2603 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2604 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2605 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2606 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2607 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2608 nlist.n_name is a pointer rather than an array.
2610 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2611 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2612 * configure.in: Use it instead of the old version.
2614 * main.c (main): Prefer setvbuf() to setlinebuf().
2616 2002-05-08 Paul D. Smith <psmith@gnu.org>
2618 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2619 (loadavg_LDADD): Ditto.
2621 2002-04-29 Paul D. Smith <psmith@gnu.org>
2623 * expand.c (recursively_expand_for_file): Rename
2624 recursively_expand() to recursively_expand_for_file() and provide
2625 an extra argument, struct file. If the argument is provided, set
2626 the variable scope to that of the file before expanding.
2627 * variable.h (recursively_expand): Make this a macro that invokes
2628 recursively_expand_for_file() with a NULL file pointer.
2629 * variable.c (target_environment): Call the renamed function and
2630 provide the current file context.
2631 Fixes Debian bug #144306.
2633 2002-04-28 Paul D. Smith <psmith@gnu.org>
2635 Allow $(call ...) user-defined variables to be self-referencing
2636 without throwing an error. Allows implementation of transitive
2637 closures, among other possibly useful things.
2638 Requested by: Philip Guenther <guenther@sendmail.com>
2640 * variable.h (struct variable): Add a new field: exp_count, and
2641 new macros to hold its size and maximum value.
2642 (warn_undefined): Make this a macro.
2643 * variable.c (define_variable_in_set): Initialize it.
2644 * expand.c (recursively_expand): If we detect recursive expansion
2645 of a variable, check the exp_count field. If it's greater than 0
2646 allow the recursion and decrement the count.
2647 (warn_undefined): Remove this (now a macro in variable.h).
2648 * function.c (func_call): Before we expand the user-defined
2649 function, modify its exp_count field to contain the maximum
2650 number of recursive calls we'll allow. After the call, reset it
2651 to 0.
2653 2002-04-21 Paul D. Smith <psmith@gnu.org>
2655 Modified to use latest autoconf (2.53), automake (1.6.1), and
2656 gettext (0.11.1). We're using gettext's new "external" support,
2657 to avoid including libintl source with GNU make.
2659 * README.cvs: New file. Explain how to build GNU make from CVS.
2661 * configure.in: Modify checking for the system glob library.
2662 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2663 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2664 etc. will manage it correctly). Set an automake conditional
2665 USE_LOCAL_GLOB to decide whether to compile the glob library.
2667 * getloadavg.c (main): Include make.h in the "TEST" program to
2668 avoid warnings.
2670 * Makefile.am: Remove special rules for loadavg. Replace them
2671 with Automake capabilities for building extra programs.
2673 * signame.c: This file does nothing if the system provide
2674 strsignal(). If not, it implements strsignal(). If the system
2675 doesn't define sys_siglist, then we make our own; otherwise we use
2676 the system version.
2677 * signame.h: Removed.
2679 * main.c (main): No need to invoke signame_init(). Update copyright.
2681 * ABOUT-NLS: Removed.
2682 * gettext.c: Removed.
2683 * gettext.h: Get a simplified copy from the gettext package.
2684 * po/*: Created.
2685 * i18n/*.po: Moved to po/.
2686 * i18n/: Removed.
2688 * config/*: Created. Contains package configuration helper files.
2689 * config.guess, config.sub: Moved to config directory.
2691 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2692 Rework to use new-style autoconf features. Use the "external"
2693 mode for gettext. Make the build.sh config file conditional on
2694 whether build.sh.in exists, to avoid autoconf errors.
2695 * acinclude.m4: Removed almost all macros as being obsolete.
2696 Rewrote remaining macros to use AC_DEFINE.
2697 * acconfig.h: Removed.
2699 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2700 conditional to handle customs support. Remove special handling
2701 for i18n features.
2703 2002-04-20 Paul D. Smith <psmith@gnu.org>
2705 * function.c (func_call): Don't mark the argument variables $1,
2706 etc. as recursive. They've already been fully expanded so
2707 there's no need to do it again, and doing so strips escaped $'s.
2708 Reported by Sebastian Glita <glseba@yahoo.com>.
2710 * remake.c (notice_finished_file): Walk through double-colon
2711 entries via the prev field, not the next field!
2712 Reported by Greg McGary <greg@mcgary.org>.
2714 * main.c (main): If the user specifies -q and asks for a specific
2715 target which is a makefile, we got an assert. In that case it
2716 turns out we should continue normally instead.
2718 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2720 * i18n/he.po: Installed a new translation.
2722 2002-01-07 Paul D. Smith <psmith@gnu.org>
2724 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2726 2001-12-04 Paul D. Smith <psmith@gnu.org>
2728 * i18n/ja.po: Installed an updated translation.
2730 2001-09-06 Paul Eggert <eggert@twinsun.com>
2732 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2733 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2735 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2736 are available.
2737 (main): Get rid of any avoidable limit on stack size.
2739 2001-09-04 Paul D. Smith <psmith@gnu.org>
2741 * i18n/da.po: Installed an updated translation.
2743 2001-08-03 Paul D. Smith <psmith@gnu.org>
2745 * i18n/fr.po: Installed an updated translation.
2746 Resolves Debian bug #106720.
2748 2001-06-13 Paul D. Smith <psmith@gnu.org>
2750 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2751 translation.
2753 2001-06-11 Paul D. Smith <psmith@gnu.org>
2755 * i18n/ko.po: Installed a new translation.
2757 2001-05-06 Paul D. Smith <psmith@gnu.org>
2759 Modify the EINTR handling.
2761 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2762 the way in which we manage the file descriptor/signal handler race
2763 trap to be more efficient.
2765 2001-05-06 Paul Eggert <eggert@twinsun.com>
2767 Restart almost all system calls that are interrupted, instead
2768 of worrying about EINTR. The lone exception is the read() for
2769 job tokens.
2771 * configure.in (HAVE_SA_RESTART): New macro.
2772 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2773 * main.c (main): Use SA_RESTART instead of the old,
2774 nonstandard SA_INTERRUPT.
2776 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2777 * main.c (bsd_signal): New function or macro,
2778 if the implementation doesn't supply it.
2779 (The bsd_signal function will be in POSIX 1003.1-200x.)
2780 (HANDLESIG): Remove.
2781 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2783 * make.h (EINTR_SET): Remove.
2784 (SA_RESTART): New macro.
2786 * arscan.c (ar_member_touch): Don't worry about EINTR.
2787 * function.c (func_shell): Likewise.
2788 * job.c (reap_children, free_child, new_job): Likewise.
2789 * main.c (main): Likewise.
2790 * remake.c (touch_file, name_mtime): Likewise.
2792 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2793 if fstat failed with errno!=EINTR, the error was ignored.
2795 * job.c (set_child_handler_action_flags): New function.
2796 (new_job): Use it to temporarily clear the SIGCHLD action flags
2797 while reading the token.
2799 2001-05-02 Paul D. Smith <psmith@gnu.org>
2801 * job.c (start_job_command): Don't add define/endef per-line flags
2802 to the top-level flags setting.
2804 2001-04-03 Paul D. Smith <psmith@gnu.org>
2806 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2807 bit on error, so check for odd return values, not non-0 return
2808 values.
2809 (VMS_get_member_info): Calculate the timezone differences correctly.
2810 Reported by John Fowler <jfowler@nyx.net>.
2813 2001-03-14 Paul D. Smith <psmith@gnu.org>
2815 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2816 value before invoking define_variable().
2817 Reported by John Fowler <jfowler@nyx.net>.
2819 2001-02-07 Paul D. Smith <psmith@gnu.org>
2821 * read.c (record_target_var): If we reset the variable due to a
2822 command-line variable setting overriding it, turn off the "append"
2823 flag.
2825 2001-01-17 Paul D. Smith <psmith@gnu.org>
2827 * variable.c (lookup_variable) [VMS]: When getting values from the
2828 environment, allocate enough space for the _value_ plus escapes,
2829 not enough space for the name plus escapes :-/.
2830 Reported by John Fowler <jfowler@nyx.net>.
2832 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2833 warnings that make generates, so it doesn't look like an error.
2834 Reported by Karl Berry <karl@gnu.org>.
2837 Fix for PR/2020: Rework appended target-specific variables. I'm
2838 fairly confident this algorithm is finally correct.
2840 * expand.c (allocated_variable_append): Rewrite. Instead of
2841 expanding each appended variable then adding all the expanded
2842 strings together, we append all the unexpanded values going up
2843 through the variable set contexts, then expand the final result.
2844 This behaves just like non-target-specific appended variable
2845 values, while the old way didn't in various corner cases.
2846 (variable_append): New function: recursively append the unexpanded
2847 value of a variable, walking from the outermost variable scope to
2848 the innermost.
2849 * variable.c (lookup_variable): Remove the code that looked up the
2850 variable set list if the found variable was "append". We don't
2851 need this anymore.
2852 (lookup_variable_in_set): Make this non-static so we can use it
2853 elsewhere.
2854 (try_variable_definition): Use lookup_variable_in_set() rather
2855 than faking out current_variable_set_list by hand (cleanup).
2856 * variable.h: Add a prototype for the now non-static
2857 lookup_variable_in_set().
2859 2000-11-17 Paul D. Smith <psmith@gnu.org>
2861 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2862 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2863 before throwing a fit.
2865 2000-11-17 Paul D. Smith <psmith@gnu.org>
2867 * read.c (readline): CRLF calculations had a hole, if you hit the
2868 buffer grow scenario just right. Reworked the algorithm to avoid
2869 the need for len or lastlen at all. Problem description with
2870 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2872 2000-10-24 Paul D. Smith <psmith@gnu.org>
2874 * gettext.c (SWAP): Declare this with the prototype, otherwise
2875 some systems don't work (non-32-bit? Reported for Cray T3E).
2876 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2878 2000-10-05 Paul D. Smith <psmith@gnu.org>
2880 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2881 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2883 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2885 2000-09-22 Paul D. Smith <psmith@gnu.org>
2887 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2888 parts of the real gettext.h here, and we expect to really include
2889 the real gettext.h later. If we keep this #define, it's ignored.
2891 2000-09-21 Paul D. Smith <psmith@gnu.org>
2893 * main.c (log_working_directory): Rework the text to use complete
2894 sentences, to make life simpler for the translators.
2896 2000-08-29 Paul D. Smith <psmith@gnu.org>
2898 * file.c (remove_intermediates): Print a debug message before we
2899 remove intermediate files, so the user (if she uses -d) knows
2900 what's going on.
2902 2000-08-21 Paul D. Smith <psmith@gnu.org>
2904 * variable.c (try_variable_definition): Change how we handle
2905 target-specific append variable defns: instead of just setting the
2906 value, expand it as an append _but_ only within the current
2907 target's context. Otherwise we lose all but the last value if the
2908 variable is appended more than once within the current target
2909 context. Fixes PR/1831.
2911 2000-08-16 Paul D. Smith <psmith@gnu.org>
2913 * function.c (func_shell): Nul-terminate the buffer before
2914 printing an exec error message (just in case it's not!).
2915 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2917 2000-07-25 Paul D. Smith <psmith@gnu.org>
2919 * job.c (construct_command_argv_internal): Add "~" to the list of
2920 sh_chars[] which disallow optimizing out the shell call.
2922 2000-07-23 Paul Eggert <eggert@twinsun.com>
2924 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2925 supersedes --disable-nsec-timestamps.
2926 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2927 * README: Remove --disable-nsec-timestamps.
2929 * filedef.h (struct file.low_resolution_time): New member.
2930 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2931 * remake.c (update_file_1):
2932 Avoid spurious rebuilds due to low resolution time stamps,
2933 generalizing the earlier code that applied only to archive members.
2934 (f_mtime): Archive members always have low resolution time stamps.
2936 * configure.in: Remove --disable-nsec-timestamps, as this has
2937 been superseded by .LOW_RESOLUTION_TIME.
2939 2000-07-23 Paul Eggert <eggert@twinsun.com>
2941 * configure.in (enable_nsec_timestamps): Renamed from
2942 make_cv_nsec_timestamps, since enable/disable options
2943 shouldn't be cached.
2945 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2946 and Paul Eggert <eggert@twinsun.com>
2948 * file.c (file_timestamp_now):
2949 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2950 so that clock_gettime is not linked unless needed.
2952 * filedef.h (FILE_TIMESTAMP_HI_RES):
2953 Remove definition; "configure" now does this.
2955 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2956 to before high resolution file timestamp check,
2957 since that check now uses uintmax_t.
2958 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2959 high resolution file timestamps.
2960 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2961 so that we don't link in clock_gettime unnecessarily.
2963 2000-07-17 Paul D. Smith <psmith@gnu.org>
2965 * i18n/ja.po: New version of the translation file.
2967 2000-07-07 Paul D. Smith <psmith@gnu.org>
2969 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2970 the offset calculation.
2971 (name_mtime): Replace EINTR test with EINTR_SET macro.
2973 2000-07-07 Paul Eggert <eggert@twinsun.com>
2975 Fix for PR/1811:
2977 * remake.c (update_file_1):
2978 Avoid spurious rebuilds of archive members due to their
2979 timestamp resolution being only one second.
2980 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2981 the clock's resolution being lower than file timestamps'.
2982 When warning about future timestamps, report only the discrepancy,
2983 not the absolute value of the timestamp and the current time.
2985 * file.c (file_timestamp_now): New arg RESOLUTION.
2986 * filedef.h (file_timestamp_now): Likewise.
2987 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2989 2000-07-05 Paul D. Smith <psmith@gnu.org>
2991 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2992 to listp. Fixes PR/1793.
2994 2000-06-26 Paul Eggert <eggert@twinsun.com>
2996 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2998 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3000 * remake.c (f_mtime): Remove unused var memtime.
3002 2000-06-25 Martin Buchholz <martin@xemacs.org>
3004 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3005 Ran spell-check on make.texinfo.
3007 2000-06-23 Paul D. Smith <psmith@gnu.org>
3009 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3010 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3011 * make.h: Define these macros.
3013 * Version 3.79.1 released.
3015 * configure.in: Add a new option, --disable-nsec-timestamps, to
3016 avoid using sub-second timestamps on systems that support it. It
3017 can lead to problems, e.g. if your makefile relies on "cp -p".
3018 * README.template: Document the issue with "cp -p".
3020 * config.guess, config.sub: Updated.
