1 2007-03-21 Paul Smith <psmith@gnu.org>
3 * configure.in: Don't turn on case-insensitive file system support
4 if --disable-... is given. Fixes Savannah bug #19348.
6 2007-03-19 Paul Smith <psmith@gnu.org>
8 * ALL: Use the strcache for all file name strings, or other
9 strings which we will never free. The goal is to save memory by
10 avoiding duplicate copies of strings. However, at the moment this
11 doesn't save much memory in most situations: due to secondary
12 expansion we actually save prerequisite lists twice (once before
13 the secondary expansion, and then again after it's been parsed
14 into individual file names in the dep list). We will resolve this
15 in a future change, by doing the parsing up-front for targets
16 where secondary expansion is not set.
18 Moving things into the strcache also allows us to use const
19 pointers in many more places.
21 2007-01-03 Paul Smith <psmith@gnu.org>
23 * make.h (ENULLLOOP): Reset errno after each failed invocation of
24 the function, not just the first. Fixes Savannah bug #18680.
26 2006-11-18 Paul Smith <psmith@gnu.org>
28 * strcache.c (strcache_add_len): Don't allocate a new buffer
29 unless the string is not already nil-terminated. Technically this
30 is a violation of the standard, since we may be passed an array
31 that is not long enough to test one past. However, in make this
32 is never true since we only use nil-terminated strings or
33 sub-strings thereof.
35 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
37 * main.c: New global cmd_prefix, defaults to '\t'.
38 * job.c (construct_command_argv_internal): Use cmd_prefix instead
39 of '\t'.
41 * dir.c: Constified.
42 (dir_contents_file_exists_p): Check for an error return from
43 readdir(), just in case.
45 * commands.c: Constified.
46 * default.c: Constified.
47 * expand.c: Constified.
48 * function.c: Partial constification.
49 * variable.c: Partial constification.
50 * vmsify.c: Constification. Hard to test this but I hope I didn't
51 screw it up!
52 * vpath.c: Partial constification.
53 * w32/pathstuff.c: Partial constification.
55 2006-11-16 Eli Zaretskii <eliz@gnu.org>
57 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
58 backslashes and drive letters as absolute.
60 2006-10-22 Paul Smith <psmith@gnu.org>
62 * main.c (struct command_switch): Use const and void*.
64 2006-10-21 Paul Smith <psmith@gnu.org>
66 * ar.c: Constified.
67 * arscan.c: Constified.
69 2006-09-30 Paul Smith <psmith@gnu.org>
71 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
72 point to lastword since the example was updated.
73 Fixes Savannah bug #16304.
74 (Secondary Expansion): Correct example description.
75 Fixes Savannah bug #16468.
76 (Makefile Contents): Clarify that comments cannot appear within
77 variable references or function calls.
78 Fixes Savannah bug #16577.
79 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
80 Fixes Savannah bug #17701.
81 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
82 (Prerequisite Types): Added an example of using order-only
83 prerequisites. Fixes Savannah bug #17880.
84 (Rule Syntax): "lise" -> "list"
85 (Multiple Rules): ... -> @dots{}
86 (Splitting Lines): ditto.
88 * remake.c (update_file_1): Prereqs that don't exist should be
89 considered changed, for the purposes of $?.
90 Fixes Savannah bug #16051.
92 * make.1: Remove extraneous "+".
93 Fixes Savannah bug #16652.
95 2006-09-06 Paul D. Smith <psmith@gnu.org>
97 * configure.in: Include sys/types.h when checking for sys/wait.h.
99 2006-08-18 Eli Zaretskii <eliz@gnu.org>
101 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
102 $PATH_SEPARATOR.
104 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
105 Normally, it is defined in config.h.
107 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
108 well.
110 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
111 sh_chars_sh for Windows platforms that emulate Unix.
113 2006-05-07 Paul D. Smith <psmith@gnu.org>
115 * README.OS2.template: Updates provided by Andreas Buening
116 <andreas.buening@nexgo.de>.

121 * config.h.W32.template (HAVE_DIRECT_H): Set it if it's available.
123 2006-04-26 Paul D. Smith <psmith@gnu.org>
125 * README.cvs: Add a reminder to notify the GNU translation robot.
127 * doc/make.texi: Change @direcategory (requested by Karl Berry).
129 2006-04-20 Paul D. Smith <psmith@gnu.org>
131 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
132 that don't have extended grep.
133 (cvsclean): Use $(PERL) instead of perl.
135 2006-04-09 Paul D. Smith <psmith@gnu.org>
137 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
139 * expand.c, implicit.c, main.c, read.c: Rename variables so that
140 inner-scope variables don't mask outer-scope variables.
142 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
143 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
144 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
145 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
146 values from memory allocation functions: they return void* and so
147 don't need to be cast. Also remove (char *) casts of arguments to
148 xrealloc().
150 * configure.in: Remove checks for memcpy/memmove/strchr.
152 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

155 calls to memset/memcpy/memmove/memcmp calls.
156 * expand.c, file.c, function.c, getloadavg.c, implicit.c: Ditto.
157 * job.c, main.c, misc.c, read.c, remake.c, rule.c: Ditto.
158 * variable.c, vpath.c: Ditto.
160 * make.h (EXIT_FAILURE): Should be 1, not 0.
162 2006-04-06 Paul D. Smith <psmith@gnu.org>
164 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
165 require an ISO C 1989 standard compiler and runtime library.
167 * Makefile.am: Remove the ansi2knr feature.
169 * make.h: Remove the PARAMS() macro definition and all uses of it.
171 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.
172 * commands.c, commands.h, config.h-vms.template: Ditto.
173 * dep.h, dir.c, expand.c, filedef.h, function.c: Ditto.
174 * implicit.c, job.c, job.h, main.c, read.c, remake.c: Ditto.
175 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
177 * NEWS: Update.
179 2006-04-01 Paul D. Smith <psmith@gnu.org>
181 Version 3.81 released.
183 * NEWS: Updated for 3.81.
185 * README.cvs: Mention that vpath builds are not supported out of
186 CVS. Fixes Savannah bug #16236.
187 Remove update of make.texi from the list of things to do; we use
188 version.texi now.
190 2006-03-26 Paul D. Smith <psmith@gnu.org>
192 * doc/make.texi: Clean up licensing. Use @copying and version.texi
193 support from automake, as described in the Texinfo manual.
195 2006-03-25 Eli Zaretskii <eliz@gnu.org>
197 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
198 with lastslash, since the latter points to filename, not to
199 target.
200 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
201 Declare and define sh_chars_sh[].
203 2006-03-23 Paul D. Smith <psmith@gnu.org>
205 * configure.in: Look for build.sh.in in $srcdir so it will be
206 built for remote configurations as well.
208 * Makefile.am: Make sure to clean up build.sh during distclean.
209 Fixes Savannah bug #16166.
211 * misc.c (log_access): Takes a const char *.
212 * function.c (fold_newlines): Takes an unsigned int *.
213 Both fixes for Savannah bug #16170.
215 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
217 * implicit.c (pattern_search): Call set_file_variables only
218 if we have prerequisites that need second expansion. Fixes
219 Savannah bug #16140.
221 2006-03-19 Paul D. Smith <psmith@gnu.org>
223 * remake.c (update_file): Add alloca(0) to clean up alloca'd
224 memory on hosts that don't support it directly.
226 * README.cvs: Add information on steps for making a release (to
227 make sure I don't forget any).
229 * main.c (clean_jobserver): Move jobserver cleanup code into a new
230 function.
231 (die): Cleanup code was removed from here; call the new function.
232 (main): If we are re-execing, clean up the jobserver first so we
233 don't leak file descriptors.
234 Reported by Craig Fithian <craig.fithian@citigroup.com>
236 2006-03-17 Paul D. Smith <psmith@gnu.org>
238 * maintMakefile (do-po-update): Rewrite this rule to clean up and
239 allow multiple concurrent runs.
240 Patch from Joseph Myers <joseph@codesourcery.com>
242 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
244 * dep.h (struct dep): Add the stem field.
245 * misc.c (alloc_dep, free_dep): New functions.
246 (copy_dep_chain): Copy stem.
247 (free_dep_chain): Use free_dep.
248 * read.c (record_files): Store stem in the dependency line.
249 * file.c (expand_deps): Use stem stored in the dependency line. Use
250 free_dep_chain instead of free_ns_chain.
251 * implicit.c (pattern_search): Use alloc_dep and free_dep.
252 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
253 * main.c (main, handle_non_switch_argument): Ditto.
254 * remake.c (check_dep): Ditto.
255 * rule.c (convert_suffix_rule, freerule): Ditto.
257 2006-03-14 Paul D. Smith <psmith@gnu.org>
259 * expand.c (variable_append): Instead of appending everything then
260 expanding the result, we expand (or not, if it's simple) each part
261 as we add it.
262 (allocated_variable_append): Don't expand the final result.
263 Fixes Savannah bug #15913.
265 2006-03-09 Paul Smith <psmith@gnu.org>
267 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
268 listed non-existent files as changed. Turns out there's a bug in
269 the Linux kernel builds which means that this change causes
270 everything to rebuild every time. We will re-introduce this fix
271 in the next release, to give them time to fix their build system.
272 Fixes Savannah bug #16002.
273 Introduces Savannah bug #16051.
275 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
276 we *don't* find UNIX "/".
277 Reported by David Ergo <david.ergo@alterface.com>
279 2006-03-04 Eli Zaretskii <eliz@gnu.org>
281 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
282 locator function find_and_set_default_shell if SHELL came from the
283 command line.
285 2006-02-20 Paul D. Smith <psmith@gnu.org>
287 * variable.c (merge_variable_set_lists): It's legal for *setlist0
288 to be null; don't core in that case.
290 2006-02-19 Paul D. Smith <psmith@gnu.org>
292 * commands.c (set_file_variables): Realloc, not malloc, the static
293 string values to avoid memory leaks.
295 * expand.c (recursively_expand_for_file): Only set reading_file to
296 an initialized value.
298 * implicit.c (pattern_search): We need to make a copy of the stem
299 if we get it from an intermediate dep, since those get freed.
301 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
302 begin with ".".
303 (enter_file) [VMS]: Ditto.
304 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
306 2006-02-24 Eli Zaretskii <eliz@gnu.org>
308 * job.c (construct_command_argv_internal): Fix last change.
310 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
311 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
312 the calls to _beginthreadex.
314 * expand.c (recursively_expand_for_file): Initialize `save' to
315 prevent compiler warnings.
317 2006-02-18 Eli Zaretskii <eliz@gnu.org>
319 * job.c (construct_command_argv_internal): Don't create a temporary
320 script/batch file if we are under -n. Call _setmode to switch the
321 script file stream to text mode.
323 2006-02-17 Paul D. Smith <psmith@gnu.org>
325 * variable.c (merge_variable_set_lists): Don't try to merge the
326 global_setlist. Not only is this useless, but it can lead to
327 circularities in the linked list, if global_setlist->next in one
328 list gets set to point to another list which also ends in
329 global_setlist.
330 Fixes Savannah bug #15757.
332 2006-02-15 Paul D. Smith <psmith@gnu.org>
334 Fix for Savannah bug #106.
336 * expand.c (expanding_var): Keep track of which variable we're
337 expanding. If no variable is being expanded, it's the same as
338 reading_file.
339 * make.h (expanding_var): Declare it.
340 * expand.c (recursively_expand_for_file): Set expanding_var to the
341 current variable we're expanding, unless there's no file info in
342 it (could happen if it comes from the command line or a default
343 variable). Restore it before we exit.
344 * expand.c (variable_expand_string): Use the expanding_var file
345 info instead of the reading_file info.
346 * function.c (check_numeric): Ditto.
347 (func_word): Ditto.
348 (func_wordlist): Ditto.
349 (func_error): Ditto.
350 (expand_builtin_function): Ditto.
351 (handle_function): Ditto.
353 2006-02-14 Paul D. Smith <psmith@gnu.org>
355 * read.c (eval): Even if the included filenames expands to the
356 empty string we still need to free the allocated buffer.
358 * implicit.c (pattern_search): If we allocated a variable set for
359 an impossible file, free it.
360 * variable.c (free_variable_set): New function.
361 * variable.h: Declare it.
363 * read.c (read_all_makefiles): Makefile names are kept in the
364 strcache, so there's never any need to alloc/free them.
365 (eval): Ditto.
367 * main.c (main): Add "archives" to the .FEATURES variable if
368 archive support is enabled.
369 * doc/make.texi (Special Variables): Document it.
371 2006-02-13 Paul D. Smith <psmith@gnu.org>
373 * implicit.c (pattern_search): Add checking for DOS pathnames to
374 the pattern rule target LASTSLASH manipulation.
375 Fixes Savannah bug #11183.
377 2006-02-11 Paul D. Smith <psmith@gnu.org>
379 * (ALL FILES): Updated copyright and license notices.
381 2006-02-10 Paul D. Smith <psmith@gnu.org>
383 A new internal capability: the string cache is a read-only cache
384 of strings, with a hash table interface for fast lookup. Nothing
385 in the cache will ever be freed, so there's no need for reference
386 counting, etc. This is the beginning of a full solution for
387 Savannah bug #15182, but for now we only store makefile names here.
389 * strcache.c: New file. Implement a read-only string cache.
390 * make.h: Add prototypes for new functions.
391 * main.c (initialize_global_hash_tables): Initialize the string cache.
392 (print_data_base): Print string cache stats.
393 * read.c (eval_makefile): Use the string cache to store makefile
394 names. Rewrite the string allocation to be sure we free everything.
396 2006-02-10 Eli Zaretskii <eliz@gnu.org>
398 * dir.c (dir_contents_file_exists_p): Don't opendir if the
399 directory time stamp didn't change, except on FAT filesystems.
400 Suggested by J. David Bryan <jdbryan@acm.org>.
402 2006-02-09 Paul D. Smith <psmith@gnu.org>
404 * function.c (func_or): Implement a short-circuiting OR function.
405 (func_and): Implement a short-circuiting AND function.
406 (function_table_init): Update the table with the new functions.
407 * doc/make.texi (Conditional Functions): Changed the "if" section
408 to one on general conditional functions. Added documentation for
409 $(and ...) and $(or ...) functions.
410 * NEWS: Note new $(and ...) and $(or ...) functions.
412 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
414 * job.h (struct child): Add the dontcare bitfield.
415 * job.c (new_job): Cache dontcare flag.
416 * job.c (reap_children): Use cached dontcare flag instead of the
417 one in struct file. Fixes Savannah bug #15641.
419 2006-02-06 Paul D. Smith <psmith@gnu.org>
421 * vpath.c (selective_vpath_search): If the file we find has a
422 timestamp from -o or -W, use that instead of the real time.
423 * remake.c (f_mtime): If the mtime is a special token from -o or
424 -W, don't overwrite it with the real mtime.
425 Fixes Savannah bug #15341.
427 Updates from Markus Mauhart <qwe123@chello.at>:
429 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
430 (process_signal, process_last_err, process_exit_code): Manage
431 invalid handle values.
432 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
433 manage invalid handles; remove them.
434 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
435 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
436 * README.cvs: Updates for building from CVS.
438 2006-02-05 Paul D. Smith <psmith@gnu.org>
440 * file.c (enter_file): Keep track of the last double_colon entry,
441 to avoid walking the list every time we want to add a new one.
442 Fixes Savannah bug #15533.
443 * filedef.h (struct file): Add a new LAST pointer.
445 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
446 the comparison. For 64-bits systems the result of the subtraction
447 might not fit into an int. Use comparison instead.
448 Fixes Savannah bug #15534.
450 * doc/make.texi: Update the chapter on writing commands to reflect
451 the changes made in 3.81 for backslash/newline and SHELL handling.
453 2006-02-01 Paul D. Smith <psmith@gnu.org>
455 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
456 variable st is not used when it's not initialized.
457 Patch from Eli Zaretskii <eliz@gnu.org>.
459 2006-01-31 Paul D. Smith <psmith@gnu.org>
461 * README.W32.template: Applied patch #4785 from
462 Markus Mauhart <qwe123@chello.at>.
463 * README.cvs: Applied patch #4786 from
464 Markus Mauhart <qwe123@chello.at>.

469 * prepare_w32.bat: Remove this file from the distribution.
471 2006-01-21 Eli Zaretskii <eliz@gnu.org>
473 * remake.c (update_goal_chain): Set g->changed instead of
474 incrementing it, as it is only 8-bit wide, and could overflow if
475 many commands got started in update_file.
477 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
479 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
480 MAXIMUM_WAIT_OBJECTS.
481 (process_wait_for_any_private): Change dimension of handles[]
482 array to MAXIMUM_WAIT_OBJECTS.
483 (process_used_slots): New function.
484 (process_register): Don't register more processes than the
485 available number of slots.
486 (process_easy): Don't start new processes if all slots are used up.
488 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
489 are already more children than sub_proc.c can handle, behave as if
490 the load were too high.
491 (start_job_command): Fix a typo in error message when process_easy
492 fails.
494 2006-01-14 Eli Zaretskii <eliz@gnu.org>
496 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
497 the shell is not sh.exe.
499 * job.c (create_batch_file): Renamed from create_batch_filename;
500 all callers changed. Don't close the temporary file; return its
501 file descriptor instead. New arg FD allows to return the file
502 descriptor.
503 (construct_command_argv_internal): Use _fdopen instead of fopen to
504 open the batch file.
506 2006-01-04 Paul D. Smith <psmith@gnu.org>
508 * readme.vms: Updates for case-insensitive VMS file systems from
509 Hartmut Becker <Hartmut.Becker@hp.com>.
510 * dir.c (vms_hash): Ditto.
511 * vmsify.c (copyto): Ditto.
512 * vmsfunctions.c (readdir): Ditto.

516 * doc/make.texi: A number of minor updates to the documentation.
518 2006-01-03 Paul D. Smith <psmith@gnu.org>
520 * remake.c (update_file_1): Mark a prerequisite changed if it
521 doesn't exist.
523 * read.c (eval): Be sure to strip off trailing whitespace from the
524 prerequisites list properly. Also, initialize all fields in
525 struct dep when creating a new one.
527 2005-12-28 Paul D. Smith <psmith@gnu.org>
529 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
530 disable warnings for MSC.
531 Patch by Rob Tulloh <rtulloh@yahoo.com>.
533 2005-12-17 Eli Zaretskii <eliz@gnu.org>
535 * doc/make.texi (Execution): Add a footnote about changes in
536 handling of backslash-newline sequences. Mention the differences
537 on MS-DOS and MS-Windows.
539 * NEWS: More details about building the MinGW port and a pointer
540 to README.W32. Fix the section name that describes the new
541 backward-incompatible processing of backslash-newline sequences.
542 The special processing of SHELL set to "cmd" is only relevant to
543 MS-Windows, not MS-DOS.
545 2005-12-17 Eli Zaretskii <eliz@gnu.org>
547 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
548 to DWORD, to avoid compiler warnings.
549 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
550 use %ld in format, to avoid compiler warnings.
552 * doc/make.texi (Special Targets): Fix a typo.
553 (Appending): Fix cross-reference to Setting.
554 (Special Variables, Secondary Expansion, File Name Functions)
555 (Flavor Function, Pattern Match, Quick Reference): Ensure two
556 periods after a sentence.
557 (Execution): Add @: after "e.g.".
558 (Environment): Fix punctuation.
559 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
560 (Shell Function, Target-specific): Add @: after "vs."
562 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
564 * read.c (record_target_var): Initialize variable's export field
565 with v_default instead of leaving it "initialized" by whatever
566 garbage happened to be on the heap.
568 2005-12-12 Paul D. Smith <psmith@gnu.org>
570 * make.1: Fix some display errors and document all existing options.
571 Patch provided by Mike Frysinger <vapier@gentoo.org>.
573 2005-12-11 Paul D. Smith <psmith@gnu.org>
575 * implicit.c (pattern_search): If 2nd expansion is not set for
576 this implicit rule, replace the pattern with the stem directly,
577 and don't re-expand the variable list. Along with the other
578 .SECONDEXPANSION changes below, fixes bug #13781.
580 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
582 * implicit.c (pattern_search): Mark other files that this rule
583 builds as targets so that they are not treated as intermediates
584 by the pattern rule search algorithm. Fixes bug #13022.
586 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
588 * remake.c (notice_finished_file): Propagate the change of
589 modification time to all the double-colon entries only if
590 it is the last one to be updated. Fixes bug #14334.
592 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
594 * function.c (func_flavor): Implement the flavor function which
595 returns the flavor of a variable.
596 * doc/make.texi (Functions for Transforming Text): Document it.
597 * NEWS: Add it to the list of new functions.
599 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
601 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
602 variable.
603 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
604 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
606 2005-10-26 Paul Smith <psmith@gnu.org>
608 * read.c (record_files): Don't set deps flags if there are no deps.
609 * maintMakefile: We only need to build the templates when we are
610 creating a distribution, so don't do it for "all".
612 2005-10-24 Paul D. Smith <psmith@gnu.org>
614 Make secondary expansion optional: its enabled by declaring the
615 special target .SECONDEXPANSION.
617 * NEWS: Update information on second expansion capabilities.
618 * doc/make.texi (Secondary Expansion): Document the
619 .SECONDEXPANSION special target and its behavior.
620 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
621 prerequisite list was found in a static pattern rule.
622 (free_dep_chain): Declare a prototype.
623 * file.c (parse_prereqs): New function: break out some complexity
624 from expand_deps().
625 (expand_deps): If we aren't doing second expansion, replace % with
626 the stem for static pattern rules. Call the new function.
627 * filedef.h (parse_prereqs): Declare a prototype.
628 * implicit.c (pattern_search): Initialize the new staticpattern
629 field.
630 * main.c (second_expansion): Declare a global variable to remember
631 if the special target has been seen. Initialize the new
632 staticpattern field for prerequisites.
633 * make.h: Extern for second_expansion.
634 * misc.c (free_dep_chain): New function: frees a struct dep list.
635 * read.c (read_all_makefiles): Initialize the staticpattern field.
636 (eval_makefile): Ditto.
637 (record_files): Check for the .SECONDEXPANSION target and set
638 second_expansion global if it's found.
639 Use the new free_dep_chain() instead of doing it by hand.
640 Set the staticpattern field for prereqs of static pattern targets.
642 2005-10-16 Paul D. Smith <psmith@gnu.org>
644 * main.c (main): Set CURDIR to be a file variable instead of a
645 default, so that values of CURDIR inherited from the environment
646 won't override the make value.
648 2005-09-26 Paul D. Smith <psmith@gnu.org>
650 * job.c (construct_command_argv_internal): If the line is empty
651 remember to free the temporary argv strings.
652 Fixes bug # 14527.
654 2005-09-16 Paul D. Smith <psmith@gnu.org>
656 * job.c (start_job_command): The noerror flag is a boolean (single
657 bit); set it appropriately.
658 Reported by Mark Eichin <eichin@metacarta.com>
660 2005-08-29 Paul D. Smith <psmith@gnu.org>
662 * function.c (func_error): On Windows, output from $(info ...)
663 seems to come in the wrong order. Try to force it with fflush().
665 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
667 * read.c (record_files): Move code that sets stem for static
668 pattern rules out of the if (!two_colon) condition so it is
669 also executed for two-colon rules. Fixes Savannah bug #13881.
671 2005-08-08 Paul D. Smith <psmith@gnu.org>
673 * make.h: Don't test that __STDC__ is non-0. Some compilers
674 (Windows for example) set it to 0 to denote "ISO C + extensions".
675 Fixes bug # 13594.
677 2005-08-07 Paul D. Smith <psmith@gnu.org>
679 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
680 conditional (slightly different version of a fix from Eli).
682 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
683 If make is running in parallel without -k and two jobs die in a
684 row, but not too close to each other, then make will quit without
685 waiting for the rest of the jobs to die.
687 * main.c (die): Don't reset err before calling reap_children() the
688 second time: we still want it to be in the error condition.
689 * job.c (reap_children): Use a static variable, rather than err,
690 to control whether or not the error message should be printed.
692 2005-08-06 Eli Zaretskii <eliz@gnu.org>
694 * w32/subproc/sub_proc.c: Include signal.h.
695 (process_pipe_io, process_file_io): Pass a pointer to a local
696 DWORD variable to GetExitCodeProcess. If the exit code is
697 CONTROL_C_EXIT, put SIGINT into pproc->signal.
699 * job.c [WINDOWS32]: Include windows.h.
700 (main_thread) [WINDOWS32]: New global variable.
701 (reap_children) [WINDOWS32]: Get the handle for the main thread
702 and store it in main_thread.
704 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
705 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
706 doing anything else. When we are done, close the main thread
707 handle and exit with status 130.
709 2005-07-30 Eli Zaretskii <eliz@gnu.org>
711 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
712 pointer to fprintf.
714 * main.c (find_and_set_default_shell): If found a DOSish shell,
715 set sh_found and the value of default_shell, and report the
716 findings in debug mode.
718 * job.c (construct_command_argv_internal): Check unixy_shell, not
719 no_default_sh_exe, to decide whether to use Unixy or DOSish
720 builtin commands.
722 * README.W32: Update with info about the MinGW build.
724 * build_w32.bat: Support MinGW.
726 * w32/subproc/build.bat: Likewise.
728 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
729 printing DWORD args.
731 * function.c (windows32_openpipe): Fix format strings for printing
732 DWORD args.
734 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
735 'reap_mode'.
736 (start_job_command): Fix format string for printing the result of
737 process_easy.
738 (start_job_command) [WINDOWS32]: Do not define.
739 (exec_command): Fix format string for printing HANDLE args.
741 * main.c (handle_runtime_exceptions): Fix sprintf format strings
742 to avoid compiler warnings.
743 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
744 (Note: some of these fixes were submitted independently by J. Grant)
746 2005-07-30 J. Grant <jg@jguk.org>
748 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
749 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
750 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
752 2005-07-15 Paul Smith <psmith@gnu.org>
754 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
755 we don't have a POSIX shell, then revert to the old
756 backslash-newline behavior (where they are stripped).
757 Fixes bug #13665.
759 2005-07-08 Paul D. Smith <psmith@gnu.org>
761 * config.h.W32.template: Reorder to match the standard config.h,
762 for easier comparisons.
763 From J. Grant <jg@jguk.org>
765 * maintMakefile: Remove .dep_segment before overwriting it, in
766 case it's not writable or noclobber is set.
767 * expand.c (variable_expand_string): Cast result of pointer
768 arithmetic to avoid a warning.
769 * main.c (switches): Add full-fledged final initializer.
771 2005-07-06 Paul D. Smith <psmith@gnu.org>
773 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
774 * signame.c (strsignal): If we found _sys_siglist[] or
775 __sys_siglist[] use those instead of sys_siglist[].
776 From Albert Chin <china@thewrittenword.com>
778 2005-07-04 Paul D. Smith <psmith@gnu.org>
780 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
781 globfree(); set up to use the GNU versions.
782 From Martin Zinser <zinser@zinser.no-ip.info>
784 2005-07-03 Paul D. Smith <psmith@gnu.org>
786 From J. Grant <jg@jguk.org>:
788 * README.W32.template: Update the Windows and tested MSVC versions.
789 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
790 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
791 * build_w32.bat: Ditto.
792 * w32/subproc/build.bat: Ditto.
794 2005-06-28 Paul D. Smith <psmith@gnu.org>
796 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
797 declaration was checked but not present.
799 2005-06-27 Paul D. Smith <psmith@gnu.org>
801 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
802 to unsigned long. Fixes Savannah bug #13550.
804 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
805 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
806 Fixes Savannah bug #13551.
808 2005-06-26 Paul D. Smith <psmith@gnu.org>
810 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
811 it if ANSI_STRING is not set.
813 2005-06-25 Paul D. Smith <psmith@gnu.org>
815 * read.c (eval): If no filenames are passed to any of the
816 "include" variants, don't print an error.
817 * doc/make.texi (Include): Document this.
818 Fixes Savannah bug #1761.
820 * job.c (construct_command_argv_internal): Sanitize handling of
821 backslash/newline pairs according to POSIX: that is, keep the
822 backslash-newline in the command script, but remove a following
823 TAB character, if present. In the fast path, make sure that the
824 behavior matches what the shell would do both inside and outside
825 of quotes. In the slow path, quote the backslash and put a
826 literal newline in the string.
827 Fixes Savannah bug #1332.
828 * doc/make.texi (Execution): Document the new behavior and give
829 some examples.
830 * NEWS: Make a note of the new behavior.
832 * make.h [WINDOWS32]: #include <direct.h>.
833 Fixes Savannah bug #13478.
835 * remake.c (name_mtime): If the stat() of a file fails and the -L
836 option was given and the file is a symlink, take the best mtime of
837 the symlink we can get as the mtime of the file and don't fail.
838 Fixes Savannah bug #13280.
840 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
841 If it's set, then don't stop on STOPCHARs or BLANKs if they're
842 inside a variable reference. Make this function static as it's
843 only used here.
844 (eval): Call find_char_unquote() with IGNOREVARS set when we're
845 parsing an unexpanded line looking for semicolons.
846 Fixes Savannah bug #1454.
847 * misc.c (remove_comments): Move this to read.c and make it static
848 as it's only used there. Call find_char_unquote() with new arg.
849 * make.h: Remove prototypes for find_char_unquote() and
850 remove_comments() since they're static now.
852 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
853 its export flag and obtain its value. When we need to re-exec,
854 increment the value and add it into the environment.
855 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
856 * NEWS: Mention MAKE_RESTARTS.
857 * main.c (always_make_set): New variable. Change the -B option to
858 set this one instead.
859 (main): When checking makefiles, only set always_make_flag if
860 always_make_set is set AND the restarts flag is 0. When building
861 normal targets, set it IFF always_make_set is set.
862 (main): Avoid infinite recursion with -W, too: only set what-if
863 files to NEW before we check makefiles if we've never restarted
864 before. If we have restarted, set what-if files to NEW _after_ we
865 check makefiles.
866 Fixes Savannah bug #7566:
868 2005-06-17 Paul D. Smith <psmith@gnu.org>
870 * default.c: Change VMS implicit rules to use $$$$ instead of $$
871 in the prerequisites list.
873 2005-06-12 Paul D. Smith <psmith@gnu.org>
875 Fix Savannah bug # 1328.
877 * configure.in: Check for atexit().
878 * misc.c (close_stdout): Test stdout to see if writes to it have
879 failed. If so, be sure to exit with a non-0 error code. Based on
880 code found in gnulib.
881 * make.h: Prototype.
882 * main.c (main): Install close_stdout() with atexit().
884 2005-06-10 Paul D. Smith <psmith@gnu.org>
886 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
888 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
889 headers; make vmsWaitForChildren() static; extern vmsify().
890 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
891 Don't create child_execute_job() here (it's in vmsjobs.c).
892 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
894 2005-06-09 Paul D. Smith <psmith@gnu.org>
896 * variable.c (push_new_variable_scope): File variables point
897 directly to the global_setlist variable. So, inserting a new
898 scope in front of that has no effect on those variables: they
899 don't go through current_variable_set_list. If we're pushing a
900 scope and the current scope is global, push it "the other way" so
901 that the new setlist is in the global_setlist variable, and
902 next points to a new setlist with the global variable set.
903 (pop_variable_scope): Properly undo a push with the new
904 semantics.
905 Fixes Savannah bug #11913.
907 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
909 * job.c (reap_children): Don't die of the command failed but
910 the dontcare flag is set. Fixes Savannah bug #13216.
912 * implicit.c (pattern_search): When creating a target from
913 an implicit rule match, lookup pattern target and set precious
914 flag in a newly created target. Fixes Savannah bug #13218.
916 2005-05-13 Paul D. Smith <psmith@gnu.org>
918 Implement "if... else if... endif" syntax.
920 * read.c (eval): Push all checks for conditional words ("ifeq",
921 "else", etc.) down into the conditional_line() function.
922 (conditional_line): Rework to allow "else if..." clause. New
923 return value -2 for lines which are not conditionals. The
924 ignoring flag can now also be 2, which means "already parsed a
925 true branch". If that value is seen no other branch of this
926 conditional can be considered true. In the else parsing if there
927 is extra text after the else, invoke conditional_line()
928 recursively to see if it's another conditional. If not, it's an
929 error. If so, raise the conditional value to this level instead
930 of creating a new conditional nesting level. Special check for
931 "else" and "endif", which aren't allowed on the "else" line.
932 * doc/make.texi (Conditional Syntax): Document the new syntax.
934 2005-05-09 Paul D. Smith <psmith@gnu.org>
936 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
937 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
938 recurses to the w32 directory, even on non-Windows systems. Use
939 the method suggested in the automake manual.
940 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
941 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
943 2005-05-07 Paul D. Smith <psmith@gnu.org>
945 * main.c (die): If we're dying with a fatal error (not that a
946 command has failed), write back any leftover tokens before we go.
948 * job.c (set_child_handler_action_flags): If there are jobs
949 waiting for the load to go down, set an alarm to go off in 1
950 second. This allows us to wake up from a potentially long-lasting
951 read() and start a new job if the load has gone down. Turn it off
952 after the read.
953 (job_noop): Dummy signal handler function.
954 (new_job): Invoke it with the new semantics.
956 * docs/make.texi: Document secondary expansion. Various cleanups
957 and random work.
959 2005-05-03 Paul D. Smith <psmith@gnu.org>
961 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
962 the targets which are to ultimately be made are called "goals";
963 see the GNU make manual. Also, MAKECMDGOALS, etc.
965 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
966 .DEFAULT_GOAL, and default_target_name to default_goal_name.
967 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
969 2005-05-02 Paul D. Smith <psmith@gnu.org>
971 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
972 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
973 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
974 functions to vmsjobs.c. #include it into jobs.c.
976 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
977 jobserver tokens. I found that this happens when an exported
978 recursive variable contains a $(shell ...) function reference: in
979 this situation we could "forget" to write back a token.
981 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
982 we have. It's not reliable to depend on the number of children in
983 our linked list so keep a separate count.
984 (new_job): Check jobserver_tokens rather than children &&
985 waiting_jobs. Increment jobserver_tokens when we get one.
986 (free_child): If jobserver_tokens is 0, internal error. If it's
987 >1, write a token back to the jobserver pipe (we don't write a
988 token for the "free" job). Decrement jobserver_tokens.
990 * main.c: Add variable master_job_slots.
991 (main): Set it to hold the number of jobs requested if we're the
992 master process, when using the jobserver.
993 (die): Sanity checks: first test jobserver_tokens to make sure
994 this process isn't holding any tokens we didn't write back.
995 Second, if master_job_slots is set count the tokens left in the
996 jobserver pipe and ensure it's the same as master_job_slots (- 1).
998 2005-04-24 Paul D. Smith <psmith@gnu.org>
1000 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1001 with -l# can lose jobserver tokens, because waiting jobs are not
1002 consulted properly when checking for the "free" token.
1004 * job.c (free_child): Count waiting_jobs as having tokens.
1005 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1006 handle jobs waiting for the load to drop.
1008 2005-04-23 Paul D. Smith <psmith@gnu.org>
1010 * main.c (main): Be careful to not core if a variable setting in
1011 the environment doesn't contain an '='. This is illegal but can
1012 happen in broken setups.
1013 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1015 2005-04-12 Paul D. Smith <psmith@gnu.org>
1017 The second expansion feature causes significant slowdown. Timing
1018 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1019 read the makefile before the feature, to 11+s to do the same
1020 operations after the feature. Additionally, memory usage
1021 increased drastically. To fix this I added some intelligence that
1022 avoids the overhead of the second expansion unless it's required.
1024 * dep.h: Add a new boolean field, need_2nd_expansion.
1026 * read.c (eval): When creating the struct dep for the target,
1027 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1028 (record_files): If there's a "%" in a static pattern rule, it gets
1029 converted to "$*" so set need_2nd_expansion to 1.
1031 * file.c (expand_deps): Rework to be more efficient. Only perform
1032 initialize_file_variables(), set_file_variables(), and
1033 variable_expand_for_file() if the need_2nd_expansion is set.
1035 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1036 (pattern_search): Ditto.
1037 * main.c (handle_non_switch_argument): Ditto.
1038 (main): Ditto.
1039 * read.c (read_all_makefiles): Ditto.
1040 (eval_makefile): Ditto.
1042 2005-04-07 Paul D. Smith <psmith@gnu.org>
1044 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1045 * variable.c (sync_Path_environment): Ditto.
1046 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1048 * main.c (main): Define the .FEATURES variable.
1049 * NEWS: Announce .FEATURES.
1050 * doc/make.texi (Special Variables): Document .FEATURES.
1052 * remake.c (check_dep): If a file is .PHONY, update it even if
1053 it's marked intermediate. Fixes Savannah bug #12331.
1055 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1057 * file.c (expand_deps): Factor out the second expansion and
1058 prerequisite line parsing logic from snap_deps().
1060 * file.c (snap_deps): Use expand_deps(). Expand and parse
1061 prerequisites of the .SUFFIXES special target first. Fixes
1062 Savannah bug #12320.
1064 2005-03-13 Paul D. Smith <psmith@gnu.org>
1066 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1067 Zaretskii.
1069 2005-03-11 Paul D. Smith <psmith@gnu.org>
1071 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1072 available, not undefined (from Earnie Boyd).
1074 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1076 * implicit.c (pattern_search): Mark an intermediate target as
1077 precious if it happened to be a prerequisite of some (other)
1078 target. Fixes Savannah bug #12267.
1080 2005-03-09 Paul D. Smith <psmith@gnu.org>
1082 * read.c (eval_makefile): Add alloca(0).
1083 (eval_buffer): Ditto.
1085 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1087 * main.c (main): Use o_file instead of o_default when defining
1088 the .DEFAULT_TARGET special variable.
1089 * read.c (eval): Use define_variable_global() instead of
1090 define_variable() when setting new value for the .DEFAULT_TARGET
1091 special variable. Fixes Savannah bug #12266.
1093 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1095 * imlicit.c (pattern_search): Mark files for which an implicit
1096 rule has been found as targets. Fixes Savannah bug #12202.
1098 2005-03-04 Paul D. Smith <psmith@gnu.org>
1100 * AUTHORS: Update.
1101 * doc/make.texi (Automatic Variables): Document $|.
1103 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1105 * read.c (record_files): Instead of substituting % with
1106 actual stem value in dependency list replace it with $*.
1107 This fixes stem triple expansion bug.
1109 * implicit.c (pattern_search): Copy stem to a separate
1110 buffer and make it a properly terminated string. Assign
1111 this buffer instead of STEM (which is not terminated) to
1112 f->stem. Instead of substituting % with actual stem value
1113 in dependency list replace it with $*. This fixes stem
1114 triple expansion bug.
1116 2005-03-01 Paul D. Smith <psmith@gnu.org>
1118 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1119 on Windows, as it takes a handle not a pid. Just exit.
1120 Fix from patch #3679, provided by Alessandro Vesely.
1122 * configure.in: Update check for sys_siglist[] from autoconf manual.
1123 * signame.c (strsignal): Update to use the new autoconf macro.
1125 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1127 * read.c (record_files): Add a check for the list of prerequisites
1128 of a static pattern rule being empty. Fixes Savannah bug #12180.
1130 2005-02-28 Paul D. Smith <psmith@gnu.org>
1132 * doc/make.texi (Text Functions): Update docs to allow the end
1133 ordinal for $(wordlist ...) to be 0.
1134 * function.c (func_wordlist): Fail if the start ordinal for
1135 $(wordlist ...) is <1. Matches documentation.
1136 Resolves Savannah support request #103195.
1138 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1139 previously we were stopping when !-q, exactly the opposite. This
1140 has been wrong since version 1.34, in 1994!
1141 (update_file): If we got an error don't break out to run more
1142 double-colon rules: just return immediately.
1143 Fixes Savannah bug #7144.
1145 2005-02-27 Paul D. Smith <psmith@gnu.org>
1147 * misc.c (end_of_token): Make argument const.
1148 * make.h: Update prototype.
1150 * function.c (abspath, func_realpath, func_abspath): Use
1151 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1152 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1153 * read.c (record_files): Ditto.
1154 * variable.c (do_variable_definition): Ditto.
1156 * function.c (func_error): Create a new function $(info ...) that
1157 simply prints the message to stdout with no extras.
1158 (function_table_init): Add new function to the table.
1159 * NEWS: Add $(info ...) reference.
1160 * doc/make.texi (Make Control Functions): Document it.
1162 New feature: if the system supports symbolic links, and the user
1163 provides the -L/--check-symlink-time flag, then use the latest
1164 mtime between the symlink(s) and the target file.
1166 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1167 readlink(). If both are available, define MAKE_SYMLINKS.
1168 * main.c: New variable: check_symlink_flag.
1169 (usage): Add a line for -L/--check-symlink-times to the help string.
1170 (switches): Add -L/--check-symlink-times command line argument.
1171 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1172 print a warning and disable it again.
1173 * make.h: Declare check_symlink_flag.
1174 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1175 if the file is a symlink then check each link in the chain and
1176 choose the NEWEST mtime we find as the mtime for the file. The
1177 newest mtime might be the file itself!
1178 * NEWS: Add information about this new feature.
1179 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1181 Avoid core dumps described in Savannah bug # 12124:
1183 * file.c: New variable snapped_deps remember whether we've run
1184 snap_deps().
1185 (snap_deps): Set it.
1186 * filedef.h: Extern it.
1187 * read.c (record_files): Check snapped_deps; if it's set then
1188 we're trying to eval a new target/prerequisite relationship from
1189 within a command script, which we don't support. Fatal.
1191 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1193 Implementation of the .DEFAULT_TARGET special variable.
1195 * read.c (eval): If necessary, update default_target_name when
1196 reading rules.
1197 * read.c (record_files): Update default_target_file if
1198 default_target_name has changed.
1199 * main.c (default_target_name): Define.
1200 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1201 default_target_name is set use default_target_file as a root
1202 target to make.
1203 * filedef.h (default_target_name): Declare.
1204 * dep.h (free_dep_chain):
1205 * misc.c (free_dep_chain): Change to operate on struct nameseq
1206 and change name to free_ns_chain.
1207 * file.c (snap_deps): Update to use free_ns_chain.
1209 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1211 Implementation of the second expansion in explicit rules,
1212 static pattern rules and implicit rules.
1214 * read.c (eval): Refrain from chopping up rule's dependencies.
1215 Store them in a struct dep as a single dependency line. Remove
1216 the code that implements SySV-style automatic variables.
1218 * read.c (record_files): Adjust the code that handles static
1219 pattern rules to expand all percents instead of only the first
1220 one. Reverse the order in which dependencies are stored so that
1221 when the second expansion reverses them again they appear in
1222 the makefile order (with some exceptions, see comments in
1223 the code). Remove the code that implements SySV-style automatic
1224 variables.
1226 * file.c (snap_deps): Implement the second expansion and chopping
1227 of dependency lines for explicit rules.
1229 * implicit.c (struct idep): Define an auxiliary data type to hold
1230 implicit rule's dependencies after stem substitution and
1231 expansion.
1233 * implicit.c (free_idep_chain): Implement.
1235 * implicit.c (get_next_word): Implement helper function for
1236 parsing implicit rule's dependency lines into words taking
1237 into account variable expansion requests. Used in the stem
1238 splitting code.
1240 * implicit.c (pattern_search): Implement the second expansion
1241 for implicit rules. Also fixes bug #12091.
1243 * commands.h (set_file_variables): Declare.
1244 * commands.c (set_file_variables): Remove static specifier.
1246 * dep.h (free_dep_chain): Declare.
1247 * misc.c (free_dep_chain): Implement.
1249 * variable.h (variable_expand_for_file): Declare.
1250 * expand.c (variable_expand_for_file): Remove static specifier.
1252 * make.h (strip_whitespace): Declare.
1253 * function.c (strip_whitespace): Remove static specifier.
1255 2005-02-26 Paul D. Smith <psmith@gnu.org>
1257 * main.c (main): Check for ferror() when reading makefiles from stdin.
1258 Apparently some shells in Windows don't close pipes properly and
1259 require this check.
1261 2005-02-24 Jonathan Grant <jg@jguk.org>
1263 * configure.in: Add MinGW configuration options, and extra w32 code
1264 directory.
1265 * Makefile.am: Add MinGW configuration options, and extra w32 code
1266 directory.
1267 * main.c: Determine correct program string (after last \ without .exe).
1268 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1269 type fix x2
1270 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1271 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1272 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1273 environment support.
1275 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1277 * function.c (func_shell): When initializing error_prefix, check
1278 that reading file name is not null. This fixes long-standing
1279 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1281 2005-02-09 Paul D. Smith <psmith@gnu.org>
1283 * maintMakefile: Update the CVS download URL to simplify them.
1284 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1285 downloading the .texi files from Savannah now.
1287 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1289 * main.c (handle_non_switch_argument): Only add variables to
1290 command_variables if they're not already there: duplicate settings
1291 waste space and can be confusing to read.
1293 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1294 this header is never included by non-WINDOWS32 code, and it
1295 requires <config.h> to define which isn't always included first.
1297 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1298 testing MINGW32 versions.
1300 * main.c (log_working_directory): flush stdout to be sure the WD
1301 change is printed before any stderr messages show up.
1303 2005-02-01 Paul D. Smith <psmith@gnu.org>
1305 * maintMakefile (po_repo): Update the GNU translation site URL.
1307 2004-12-01 Paul D. Smith <psmith@gnu.org>
1309 * main.c (main): Change char* env_shell to struct variable shell_var.
1310 * variable.c (target_environment): Use new shell_var.
1312 2004-11-30 Paul D. Smith <psmith@gnu.org>
1314 * configure.in: The old way we avoided creating build.sh from
1315 build.sh.in before build.sh.in exists doesn't work anymore; we
1316 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1317 the help!). This also keeps automake from complaining.
1318 * Makefile.am (README): Add a dummy target so automake won't
1319 complain that this file doesn't exist when we checkout from CVS.
1320 * maintMakefile (.dep_segment): Rewrite this rule since newer
1321 versions of automake don't provide DEP_FILES.
1323 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1325 Implementation of `realpath' and `abspath' built-in functions.
1327 * configure.in: Check for realpath.
1328 * function.c (abspath): Return an absolute file name that does
1329 not contain any `.' or `..' components, nor repeated `/'.
1330 * function.c (func_abspath): For each name call abspath.
1331 * function.c (func_realpath): For each name call realpath
1332 from libc or delegate to abspath if realpath is not available.
1333 * doc/make.texi (Functions for File Names): Document new functions.
1334 * doc/make.texi (Quick Reference): Ditto.
1336 2004-11-28 Paul D. Smith <psmith@gnu.org>
1338 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1339 arguments. Fixes bug #10252.
1341 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1343 * main.c (main): Set SHELL to v_noexport by default. Remember the
1344 original environment setting of SHELL in the env_shell variable.
1345 * main.h: Export new env_shell variable.
1346 * variable.c (target_environment): If we find a v_noexport
1347 variable for SHELL, add a SHELL variable with the env_shell value.
1348 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1349 * doc/make.texi (Variables/Recursion): Ditto.
1351 2004-11-28 Paul D. Smith <psmith@gnu.org>
1353 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1354 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1355 Patch by Alessandro Vesely.
1357 2004-11-12 Paul D. Smith <psmith@gnu.org>
1359 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1360 the command line if it's inside a string.
1361 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1363 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1365 * function.c (func_lastword): New function: return last word
1366 from the list of words.
1367 * doc/make.texi: Document $(lastword ). Fix broken links in
1368 Quick Reference section.
1370 2004-10-06 Paul D. Smith <psmith@gnu.org>
1372 Apply patch from Alessandro Vesely, provided with bug # 9748.
1373 Fix use of tmpnam() to work with Borland C.
1375 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1376 construction of a temporary filename, and call new function
1377 create_batch_filename().
1378 (create_batch_filename) [WINDOWS32]: New function to create a
1379 temporary filename.
1381 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1383 * read.c (record_target_var): Expand simple pattern-specific
1384 variable.
1385 * variable.c (initialize_file_variables): Do not expand simple
1386 pattern-specific variable.
1388 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1390 * remake.c (update_file_1): When rebuilding makefiles inherit
1391 dontcare flag from a target that triggered update.
1393 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1395 * variable.c (initialize_file_variables): Mark pattern-specific
1396 variable as a per-target and copy export status.
1398 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1400 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1402 * implicit.c (pattern_search): When considering an implicit rule's
1403 prerequisite check that it is actually a target rather then
1404 just an entry in the file hashtable.
1406 2004-09-21 Paul D. Smith <psmith@gnu.org>
1408 * read.c (readstring): Fix some logic errors in backslash handling.
1409 (eval): Remove some unnecessary processing in buffer handling.
1410 (record_target_var): Assert that parse_variable_definition() succeeded.
1411 Reported by: Markus Mauhart <qwe123@chello.at>.
1413 * misc.c: Removed the sindex() function. All instances of this
1414 function were trivially replaceable by the standard strstr()
1415 function, and that function will always have better (or certainly
1416 no worse) performance than the very simple-minded algorithm
1417 sindex() used. This can matter with complex makefiles.
1418 * make.h: Remove the prototype for sindex().
1419 * function.c (subst_expand): Convert sindex() call to strstr().
1420 This means we no longer need to track the TLEN value so remove that.
1421 (func_findstring): Convert sindex() to strstr().
1422 * commands.c (chop_commands): Convert sindex() calls to strstr().
1423 Suggested by: Markus Mauhart <qwe123@chello.at>.
1425 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1426 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1427 If SHELL is set to CMD.EXE then assume it's batch-mode and
1428 non-unixy. I wrote the code differently from the patch, though,
1429 to make it safer. This also resolves bug #9174.
1431 2004-09-20 Paul D. Smith <psmith@gnu.org>
1433 * expand.c (variable_expand_string): Modify to invoke
1434 patsubst_expand() instead of subst_expand(); the latter didn't
1435 handle suffix patterns correctly.
1436 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1437 was used only from variable_expand_string() and is no longer used
1438 there.
1439 (func_subst): Ditto, on call to subst_expand().
1440 (patsubst_expand): Require the percent pointers to point to the
1441 character after the %, not to the % itself.
1442 * read.c (record_files): New call criteria for patsubst_expand().
1443 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1444 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1446 2004-09-19 Paul D. Smith <psmith@gnu.org>
1448 * function.c (subst_expand): Fix a check in by_word: look for a
1449 previous blank if we're beyond the beginning of the string, not
1450 the beginning of the word.
1451 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1453 2004-05-16 Paul D. Smith <psmith@gnu.org>
1455 * remake.c (update_goal_chain): Change the argument specifying
1456 whether we're rebuilding makefiles to be a global variable,
1457 REBUILDING_MAKEFILES.
1458 (complain): Extract the code that complains about no rules to make
1459 a target into a separate function.
1460 (update_file_1): If we tried to rebuild a file during the makefile
1461 rebuild phase and it was dontcare, then no message was printed.
1462 If we then try to build the same file during the normal build,
1463 print a message this time.
1464 (remake_file): Don't complain about un-remake-able files when
1465 we're rebuilding makefiles.
1467 2004-05-11 Paul D. Smith <psmith@gnu.org>
1469 * job.c (construct_command_argv_internal): OS/2 patches from
1470 Andreas Buening <andreas.buening@nexgo.de>.
1472 2004-05-10 Paul D. Smith <psmith@gnu.org>
1474 * remake.c (update_file): Don't walk the double-colon chain unless
1475 this is a double-colon rule. Fix suggested by Boris Kolpackov
1476 <boris@kolpackov.net>.
1478 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1479 * readme.vms: New section describing OpenVMS support and issues.
1480 * default.c (default_variables): Add support for IA64.
1481 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1482 without some privilege aborts make with the error
1483 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1484 pressing Ctrl+Y and the input device is no terminal. The change
1485 catches this error and just continues.
1487 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1489 2004-04-25 Paul D. Smith <psmith@gnu.org>
1491 * commands.c (set_file_variables): Set $< properly in the face of
1492 order-only prerequisites.
1493 Patch from Boris Kolpackov <boris@kolpackov.net>
1495 2004-04-21 Bob Byrnes <byrnes@curl.com>
1497 * main.c (main): Notice failures to remake makefiles.
1499 2004-03-28 Paul D. Smith <psmith@gnu.org>
1501 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1503 * job.c: No default shell for RISC OS.
1504 (load_too_high): Hard-code the return to 1.
1505 (construct_command_argv_internal): No sh_chars or sh_cmds.
1506 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1508 2004-03-20 Paul D. Smith <psmith@gnu.org>
1510 * variable.c (do_variable_definition): Don't append from the
1511 global set if a previous non-appending target-specific variable
1512 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1513 (with fix).
1515 * expand.c (reference_variable): Don't give up on variables with
1516 no value that have the target-specific append flag set: they might
1517 have a value after all. Reported by Oliver Schmidt
1518 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1519 <nikulin@dx1cmd.inp.nsk.su>.
1521 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1522 refer to absolute pathnames in directories that don't exist: some
1523 portion of the makefile could create those directories before we
1524 match the pattern. Fixes bugs #775 and #108.
1526 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1528 * main.c (main): Free makefile_mtimes if we have any.
1529 * README.W32.template: Update documentation for the current status
1530 of the MS-Windows port.
1531 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1532 environment variable is sometimes already defined which causes the
1533 build to fail.
1534 * main.c (debug_signal_handler): Only define this function if
1535 SIGUSR1 is available.
1537 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1539 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1540 * README.OS2.template: Documentation updates.
1541 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1542 link line for safety.
1543 * maintMakefile (build.sh.in): Remove an extraneous ")".
1544 * job.c (child_execute_job): Close saved FDs.
1545 * job.c (exec_command) [OS/2]: exec_command(): If the command
1546 can't be exec'ed and if the shell is not Unix-sh, then try again
1547 with argv = { "cmd", "/c", ... }. Normally, this code is never
1548 reached for the cmd shell unless the command really doesn't exist.
1549 (construct_command_argv_internal) [OS/2]: The code for cmd
1550 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1551 The CMD builtin commands are case insensitive so use strcasecmp().
1553 2004-03-19 Paul D. Smith <psmith@gnu.org>
1555 * read.c (do_define): Re-order line counter increment so the count
1556 is accurate (we were losing one line per define). Reported by
1557 Dave Yost <Dave@Yost.com>.
1559 2004-03-06 Paul D. Smith <psmith@gnu.org>
1561 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1562 compiler.
1563 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1564 * misc.c (message,error,fatal): Ditto.
1565 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1566 * config.h.W32.template: Ditto.
1567 * config.h-vms.template: Ditto.
1568 * config.ami.template: Ditto.
1570 2004-03-04 Paul D. Smith <psmith@gnu.org>
1572 * README.template: Add a note about broken /bin/sh on SunOS
1573 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1575 * misc.c (message, error, fatal): Don't use "..." if we're using
1576 varargs. ansi2knr should handle this but it doesn't work: it
1577 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1578 done. On many systems (SunOS for example) va_dcl is a #define.
1579 So, force the use of the non-"..." version on pre-ANSI compilers.
1581 * maintMakefile (sign-dist): Create some rules to help automate
1582 the new GNU ftp upload method.
1584 2004-02-24 Paul D. Smith <psmith@gnu.org>
1586 * config.h.W32.template: Add HAVE_STDARG_H
1587 * config.h-vms.template: Ditto.
1588 * config.ami.template: Ditto.
1590 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1592 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1593 * build_w32.bat: Remove extra "+".
1595 2004-02-23 Paul D. Smith <psmith@gnu.org>
1597 * make.h: Create an UNUSED macro to mark unused parameters.
1598 * (many): Clean up warnings by applying UNUSED, fixing
1599 signed/unsigned incompatibilities, etc.
1601 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1602 autoconf warnings.
1603 * filedef.h: Name the command_state enumeration.
1604 * file.c (set_command_state): Use the enumeration in the function
1605 argument.
1607 * configure.in: Explicitly set SET_MAKE to empty, to disable
1608 MAKE=make even when no make already exists. Fix bug #3823.
1610 2004-02-22 Paul D. Smith <psmith@gnu.org>
1612 * maintMakefile: Perl script to clean up all non-CVS files. Use
1613 it on all the subdirectories for the cvs-clean target.
1615 * main.c (decode_switches): Require non-empty strings for all our
1616 string command-line options. Fixes Debian bug # 164165.
1618 * configure.in: Check for stdarg.h and varargs.h.
1619 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1620 for printing messages.
1621 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1622 (message): Ditto.
1623 (error): Ditto.
1624 (fatal): Ditto.
1626 A number of patches for OS/2 support from Andreas Buening
1627 <andreas.buening@nexgo.de>:
1629 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1630 disable the SIGCHLD handler.
1631 (reap_children) [OS/2]: Remove special handling of job_rfd.
1632 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1633 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1634 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1635 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1636 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1637 systems.
1639 2004-02-21 Paul D. Smith <psmith@gnu.org>
1641 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1642 <mail@kristov.de> reports that if process_begin() fails we don't
1643 handle the error condition correctly in all cases.
1644 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1645 to have a newline on the message.
1647 * job.c (construct_command_argv_internal): Add "test" to UNIX
1648 sh_cmds[]. Fixes Savannah bug # 7606.
1650 2004-02-04 Paul D. Smith <psmith@gnu.org>
1652 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1653 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1654 Hartmut Becker <Hartmut.Becker@hp.com>.
1656 2004-01-21 Paul D. Smith <psmith@gnu.org>
1658 * job.c (load_too_high): Implement an algorithm to control the
1659 "thundering herd" problem when using -l to control job creation
1660 via the load average. The system only recomputes the load once a
1661 second but we can start many jobs in a second. To solve this we
1662 keep track of the number of jobs started in the last second and
1663 apply a weight to try to guess what a correct load would be.
1664 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1665 Also fixes bug #4693.
1666 (reap_children): Decrease the job count for this second.
1667 (start_job_command): Increase the job count for this second.
1669 * read.c (conditional_line): Expand the text after ifn?def before
1670 checking to see if it's a single word. Fixes bug #7257.
1672 2004-01-09 Paul D. Smith <psmith@gnu.org>
1674 * file.c (print_file): Recurse to print all targets in
1675 double-colon rules. Fixes bug #4518, reported (with patch) by
1676 Andrew Chatham <chatham@google.com>.
1678 2004-01-07 Paul D. Smith <psmith@gnu.org>
1680 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1681 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1682 AC_FUNC_SETVBUF_REVERSED.
1684 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1685 (MAKE Variable): Fix Savannah bug #4898.
1687 * job.c (construct_command_argv_internal): Add "!" to the list of
1688 shell escape chars. POSIX sh allows it to appear before a
1689 command, to negate the exit code. Fixes bug #6404.
1691 * implicit.c (pattern_search): When matching an implicit rule,
1692 remember which dependencies have the ignore_mtime flag set.
1693 Original fix provided in Savannah patch #2349, by Benoit
1694 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1696 2003-11-22 Paul D. Smith <psmith@gnu.org>
1698 * README.W32.template (Outputs): Clarification on -j with
1699 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1700 <jg-make@jguk.org>.
1702 2003-11-02 Paul D. Smith <psmith@gnu.org>
1704 * function.c (func_if): Strip all the trailing whitespace from the
1705 condition, then don't expand it. Fixed bug # 5798.
1707 * expand.c (recursively_expand_for_file): If we're expanding a
1708 variable with no file context, then use the variable's context.
1709 Fixes bug # 6195.
1711 2003-10-21 Paul D. Smith <psmith@gnu.org>
1713 * main.c (log_working_directory): Add newlines to printf()s.
1715 * README.cvs: Add a note to ignore warnings during autoreconf.
1717 * maintMakefile (po_repo): Set a new URL for PO file updates.
1718 (get-config/config.guess get-config/config.sub): Get these files
1719 from the Savannah config project instead of ftp.gnu.org.
1721 2003-10-05 Paul Eggert <eggert@twinsun.com>
1723 * main.c (main): Avoid potential subscript error if environ has
1724 short strings.
1726 2003-08-22 Paul D. Smith <psmith@gnu.org>
1728 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1729 systems which don't yet implement the C89 standard :-/.
1731 2003-07-18 Paul D. Smith <psmith@gnu.org>
1733 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1734 [WINDOWS32]: Initialize hash.
1736 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1738 * dir.c (read_dirstream): Provide a workaround for broken versions of
1739 the MinGW dirent structure.
1741 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1743 * w32/include/dirent.h: Add __MINGW32__ filter.
1745 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1747 * make.h: Add global declaration of *make_host.
1748 * main.c (print_usage): Remove local declaration of *make_host.
1749 (print_version): Display "This program built for ..." after Copyright
1750 notice.
1752 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1754 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1755 execution of "makeinfo --html make.texi".
1757 2003-04-30 Paul D. Smith <psmith@gnu.org>
1759 * build.template: Make some changes to maybe allow this script to
1760 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1762 * README.OS2.template: New file for OS/2 support. Original
1763 contributed by Andreas Buening.
1764 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1765 DOS-style paths.
1767 2003-04-19 Paul D. Smith <psmith@gnu.org>
1769 Fix bug #1405: allow a target to match multiple pattern-specific
1770 variables.
1772 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1773 variable.c, where they've always belonged.
1774 * rule.h: Move the prototypes and struct pattern_var as well.
1775 * variable.c (initialize_file_variables): Invoke
1776 lookup_pattern_var() in a loop, until no more matches are found.
1777 If a match is found, create a new variable set for the target's
1778 pattern variables. Then merge the contents of each matching
1779 pattern variable set into the target's pattern variable set.
1780 (lookup_pattern_var): Change this function to be usable
1781 in a loop. It takes a starting position: if NULL, start at the
1782 beginning; if non-NULL, start with the pattern variable after that
1783 position, and return the next matching pattern.
1784 (create_pattern_var): Create a unique instance of
1785 pattern-specific variables for every definition in the makefile.
1786 Don't combine the same pattern together. This allows us to
1787 process the variable handling properly even when the same pattern
1788 is used multiple times.
1789 (parse_variable_definition): New function: break out the parsing
1790 of a variable definition line from try_variable_definition.
1791 (try_variable_definition): Call parse_variable_definition to
1792 parse.
1793 (print_variable_data_base): Print out pattern-specific variables.
1794 * variable.h (struct variable): Remember when a variable is
1795 conditional. Also remember its flavor.
1796 (struct pattern_var): Instead of keeping a variable set, we just
1797 keep a single variable for each pattern.
1798 * read.c (record_target_var): Each pattern variable contains only a
1799 single variable, not a set, so create it properly.
1800 * doc/make.texi (Pattern-specific): Document the new behavior.
1802 2003-04-17 Paul D. Smith <psmith@gnu.org>
1804 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1805 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1806 file/directory naming rules for VMS so I can't tell whether this
1807 is correct or not.
1809 2003-04-09 Paul D. Smith <psmith@gnu.org>
1811 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1812 DOS-style pathnames: backslash separators and drive specifiers.
1814 2003-03-28 Paul D. Smith <psmith@gnu.org>
1816 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1817 the intermediate flag on all targets. Fixes bug #2515.
1819 2003-03-24 Paul D. Smith <psmith@gnu.org>
1821 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1822 Upgrade to autoconf 2.57 and automake 1.7.3.
1824 * job.c: More OS/2 changes from Andreas Buening.
1826 * file.c (print_file): Fix variable initialization.
1827 Fixes bug #2892.
1829 * remake.c (notice_finished_file):
1831 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1832 some calls (like readdir()) return NULL in valid situations
1833 without resetting errno. Fixes bug #2846.
1835 2003-02-25 Paul D. Smith <psmith@gnu.org>
1837 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1839 * job.c (_is_unixy_shell) [OS/2]: New function.
1840 Set default shell to /bin/sh.
1841 (reap_children): Close the job_rfd pipe here since we don't use a
1842 SIGCHLD handler.
1843 (set_child_handler_action_flags): define this to empty on OS/2.
1844 (start_job_command): Close the jobserver pipe and use
1845 child_execute_job() instead of fork/exec.
1846 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1847 rather than exec'ing, then reconfigure stdin/stdout.
1848 (exec_command): Rewrite to use spawn instead of exec. Return the
1849 PID of the child.
1851 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1852 in DOS. Handle the TEMP environment variable as in DOS. Don't
1853 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1854 use -j in DOS mode. Use child_execute_job() instead of
1855 exec_command().
1857 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1858 spawn() instead.
1860 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1861 prototypes that return values.
1863 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1865 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1866 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1867 for OS/2.
1868 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1869 DOS paths.
1871 2003-02-24 Paul D. Smith <psmith@gnu.org>
1873 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1874 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1875 (child_execute_job) [VMS]: Handle error status properly.
1876 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1878 * function.c (func_shell): Use EINTRLOOP() while reading from the
1879 subshell pipe (Fixes bug #2502).
1880 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1881 jobserver pipe.
1882 * main.c (main): Ditto.
1884 2003-01-30 Paul D. Smith <psmith@gnu.org>
1886 * read.c (eval): eval() was not fully reentrant, because the
1887 collapsed buffer was static. Change it to be an automatic
1888 variable so that eval() can be invoked recursively.
1889 Fixes bug # 2238.
1890 (eval): Apply patch # 1022: fix memory reference error on long
1891 target-specific variable lines.
1892 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1894 * function.c (check_numeric): Combine the is_numeric() function
1895 into this function, since it's only called from one place.
1896 Constify this function. Have it print the incorrect string in the
1897 error message. Fixes bug #2407.
1898 (strip_whitespace): Constify.
1899 (func_if): Constify.
1900 * expand.c (expand_argument): Constify.
1902 2003-01-29 Paul D. Smith <psmith@gnu.org>
1904 Fix bug # 2169, also reported by other people on various systems.
1906 * make.h: Some systems, such as Solaris and PTX, do not fully
1907 implement POSIX-compliant SA_RESTART functionality; important
1908 system calls like stat() and readdir() can still fail with EINTR
1909 even if SA_RESTART has been set on the signal handler. So,
1910 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1911 EINTR for system calls which return -1 or 0 (NULL), respectively,
1912 on error.
1913 Also, remove the old atomic_stat()/atomic_readdir() and
1914 HAVE_BROKEN_RESTART handling.
1916 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1918 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1919 * remake.c (touch_file): Ditto.
1921 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1922 * read.c (construct_include_path): Ditto.
1923 * remake.c (name_mtime): Ditto.
1924 * vpath.c (selective_vpath_search): Ditto.
1925 * dir.c (find_directory): Ditto.
1926 (local_stat): Ditto.
1927 (find_directory): Use ENULLLOOP() to wrap opendir().
1928 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1930 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1931 atomic_readdir() handling.
1933 2003-01-22 Paul D. Smith <psmith@gnu.org>
1935 * function.c (func_call): Fix Bug #1744. If we're inside a
1936 recursive invocation of $(call ...), mask any of the outer
1937 invocation's arguments that aren't used by this one, so that this
1938 invocation doesn't "inherit" them accidentally.
1940 2002-12-05 Paul D. Smith <psmith@gnu.org>
1942 * function.c (subst_expand): Valery Khamenia reported a
1943 pathological performance hit when doing substitutions on very
1944 large values with lots of words: turns out we were invoking
1945 strlen() a ridiculous number of times. Instead of having each
1946 call to sindex() call strlen() again, keep track of how much of
1947 the text we've seen and pass the length to sindex().
1949 2002-11-19 Paul D. Smith <psmith@gnu.org>
1951 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1954 2002-11-16 Paul D. Smith <psmith@gnu.org>
1956 * NMakefile.template (OBJS): Add hash.c object file.
1957 * SMakefile.template (srcs): Ditto.
1958 * Makefile.ami (objs): Ditto.
1959 * build_w32.bat: Ditto.
1961 * Makefile.DOS.template: Remove extra dependencies.
1963 2002-10-25 Paul D. Smith <psmith@gnu.org>
1965 * expand.c (install_variable_buffer): New function. Install a new
1966 variable_buffer context and return the previous one.
1967 (restore_variable_buffer): New function. Free the current
1968 variable_buffer context and put a previously saved one back.
1969 * variable.h: Prototypes for {install,restore}_variable_buffer.
1970 * function.c (func_eval): Push a new variable_buffer context
1971 before we eval, then restore the old one when we're done.
1972 Fixes Bug #1517.
1974 * read.c (install_conditionals): New function. Install a new
1975 conditional context and return the previous one.
1976 (restore_conditionals): New function. Free the current
1977 conditional context and put a previously saved one back.
1978 (eval): Use the {install,restore}_conditionals for "include"
1979 handling.
1980 (eval_buffer): Use {install,restore}_conditionals to preserve the
1981 present conditional state before we evaluate the buffer.
1982 Fixes Bug #1516.
1984 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1985 and $(value ...).
1986 (Recursion): Add a variable index entry for CURDIR.
1988 * README.cvs: Update to appropriate versions.
1989 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1990 don't need to copy loadavg.c: automake is smart enough to create
1991 it for me. Still have a bug in automake related to ansi2knr tho.
1993 2002-10-14 Paul D. Smith <psmith@gnu.org>
1995 * remake.c (notice_finished_file): Only touch targets if they have
1996 at least one command (as per POSIX). Resolve Bug #1418.
1998 * *.c: Convert to using ANSI C-style function definitions.
1999 * Makefile.am: Enable the ansi2knr feature of automake.
2000 * configure.in: ditto.
2002 2002-10-13 Paul D. Smith <psmith@gnu.org>
2004 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2005 for automatic variable values like $^, etc. In the case of very
2006 large lists of prerequisites this causes problems. Instead reuse
2007 a static buffer (resizeable) for each variable.
2009 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2010 target-specific variable definitions. Check for it and set an
2011 "exported" flag.
2012 (record_target_var): Set the export field to v_export if the
2013 "exported" flag is set.
2014 * doc/make.texi (Target-specific): Document the ability to use
2015 "export".
2017 * doc/make.texi: Change the name of the section on automatic
2018 variables from "Automatic" to "Automatic Variables". Added text
2019 clarifying the scope of automatic variables.
2021 2002-10-04 Paul D. Smith <psmith@gnu.org>
2023 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2024 as () braces.
2025 (record_files): Ditto.
2027 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2028 the search for the '=' to only within the enclosing parens.
2030 2002-10-03 Paul D. Smith <psmith@gnu.org>
2032 Version 3.80 released.
2034 * dir.c: Change hash functions to use K&R function definition style.
2035 * function.c: Ditto.
2036 * read.c: Ditto.
2037 * variable.c: Ditto.
2039 Update to automake 1.7.
2041 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2042 (pdf): Remove this target as automake now provides one.
2044 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2046 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2048 * makefile.com: Updates for GNU make 3.80.
2049 * makefile.vms: Ditto.
2051 2002-09-23 Paul D. Smith <psmith@gnu.org>
2053 * read.c (enum make_word_type): Remove w_comment.
2054 (get_next_mword): Don't treat comment characters as special; where
2055 this function is used we will never see a comment (it's stripped
2056 before we get here) and treating comments specially means that
2057 targets like "foo\#bar" aren't handled properly.
2059 2002-09-18 Paul D. Smith <psmith@gnu.org>
2061 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2063 * read.c (eval): Expansion of arguments to export/unexport was
2064 ignoring all arguments after the first one. Change the algorithm
2065 to expand the whole line once, then parse the results.
2067 2002-09-17 Paul D. Smith <psmith@gnu.org>
2069 Fix Bug #940 (plus another bug I found while looking at this):
2071 * read.c (record_target_var): enter_file() will add a new entry if
2072 it's a double-colon target: we don't want to do that in this
2073 situation. Invoke lookup_file() and only enter_file() if it does
2074 not already exist. If the file we get back is a double-colon then
2075 add this variable to the "root" double-colon target.
2077 * variable.c (initialize_file_variables): If this file is a
2078 double-colon target but is not the "root" target, then initialize
2079 the root and make the root's variable list the parent of our
2080 variable list.
2082 2002-09-13 Paul D. Smith <psmith@gnu.org>
2084 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2086 * hash.c (round_up_2): Get rid of a warning.
2088 2002-09-12 Paul D. Smith <psmith@gnu.org>
2090 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2091 so it doesn't complain about getloadavg.c.
2093 * commands.c (set_file_variables): Make sure we always alloca() at
2094 least 1 character for the value of $? (for '\0').
2096 2002-09-11 Paul D. Smith <psmith@gnu.org>
2098 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2099 macro to use RESULT instead of the incorrect _RESULT_.
2101 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2102 and atomic_readdir(). We need to #include dirent.h to get this to
2103 work.
2104 * misc.c (atomic_readdir): Fix typos.
2106 2002-09-10 Paul D. Smith <psmith@gnu.org>
2108 * read.c (eval): Expand variable lists given to export and
2109 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2110 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2112 * doc/make.texi (Variables/Recursion): Document this.
2113 (Conditional Syntax): And here.
2115 2002-09-09 Paul D. Smith <psmith@gnu.org>
2117 * configure.in: Check for memmove().
2119 2002-09-07 Paul D. Smith <psmith@gnu.org>
2121 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2122 Michael Sterrett <msterret@coat.com> reports that while it has
2123 SA_RESTART, it does not work properly.
2125 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2126 that invokes stat() and loops to do it again if it returns EINTR.
2127 (atomic_readdir): Ditto, with readdir().
2129 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2130 and readdir() to atomic_stat() and atomic_readdir().
2132 2002-09-04 Paul D. Smith <psmith@gnu.org>
2134 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2135 reports that GNU make sometimes doesn't recognize that targets can
2136 be made, when directories can be created as prerequisites. He
2137 reports that changing the order of predicates in the DEP->changed
2138 flag test so that lookup_file() is always performed, solves this
2139 problem.
2141 2002-08-08 Paul D. Smith <psmith@gnu.org>
2143 * configure.in: Require a newer version of gettext.
2145 * misc.c (perror_with_name): Translate the format string (for
2146 right-to-left language support).
2147 (pfatal_with_name): Ditto.
2149 * main.c: Create a static array of strings to store the usage
2150 text. This is done to facilitate translations.
2151 (struct command_switch): Remove argdesc and description fields.
2152 (switches): Remove values for obsolete fields.
2153 (print_usage): Print each element of the usage array.
2155 * hash.c: Change function definitions to be K&R style.
2157 2002-08-02 Paul D. Smith <psmith@gnu.org>
2159 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2160 this one because it's too hard to get right. We'll look at it for
2161 a future release.
2162 * main.c (main): Don't create the .TARGETS variable.
2163 * variable.c (handle_special_var): Don't handle .TARGETS.
2165 2002-08-01 Paul D. Smith <psmith@gnu.org>
2167 * main.c (switches): Add a new option, -B (--always-make). If
2168 specified, make will rebuild all targets that it encounters even
2169 if they don't appear to be out of date.
2170 (always_make_flag): New flag.
2171 * make.h: Extern always_make_flag.
2172 * remake.c (update_file_1): Check always_make_flag; if it's set we
2173 will always rebuild any target we can, even if none of its
2174 prerequisites are newer.
2175 * NEWS: Mention it.
2177 * doc/make.texi (Shell Function): Make it clear that make
2178 variables marked as "export" are not passed to instances of the
2179 shell function.
2181 Add new introspection variable .VARIABLES and .TARGETS.
2183 * variable.c (handle_special_var): New function. If the variable
2184 reference passed in is "special" (.VARIABLES or .TARGETS),
2185 calculate the new value if necessary. .VARIABLES is handled here:
2186 walk through the hash of defined variables and construct a value
2187 which is a list of the names. .TARGETS is handled by
2188 build_target_list().
2189 (lookup_variable): Invoke handle_special_var().
2190 * file.c (build_target_list): Walk through the hask of known files
2191 and construct a list of the names of all the ones marked as
2192 targets.
2193 * main.c (main): Initialize them to empty (and as simple variables).
2194 * doc/make.texi (Special Variables): Document them.
2195 * NEWS: Mention them.
2197 * variable.h (struct variable): Add a new flag "exportable" which
2198 is true if the variable name is valid for export.
2199 * variable.c (define_variable_in_set): Set "exportable" when a new
2200 variable is defined.
2201 (target_environment): Use the "exportable" flag instead of
2202 re-checking the name here... an efficiency improvement.
2204 2002-07-31 Paul D. Smith <psmith@gnu.org>
2206 * config.h-vms.template: Updates to build on VMS. Thanks to
2207 Brian_Benning@aksteel.com for helping verify the build.
2208 * makefile.com: Build the new hash.c file.
2209 * hash.h: Use strcpmi(), not stricmp(), in the
2210 HAVE_CASE_INSENSITIVE_FS case.
2212 2002-07-30 Paul D. Smith <psmith@gnu.org>
2214 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2215 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2216 Reported by <Brian_Benning@aksteel.com>.
2218 2002-07-10 Paul D. Smith <psmith@gnu.org>
2220 * variable.c (pop_variable_scope): Remove variable made unused by
2221 new hash infrastructure.
2222 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2223 comparisons as well as name comparisons.
2224 * variable.h: Add a prototype for new hash_init_function_table().
2225 * file.c (lookup_file): Remove variables made unused by new hash
2226 infrastructure.
2227 * dir.c (directory_contents_hash_2): Missing return of hash value.
2228 (dir_contents_file_exists_p): Remove variables made unused by new
2229 hash infrastructure.
2232 Installed Greg McGary's integration of the hash functions from the
2233 GNU id-utils package:
2235 2002-07-10 Greg McGary <greg@mcgary.org>
2237 * scripts/functions/filter-out: Add literals to to the
2238 pattern space in order to add complexity, and trigger
2239 use of an internal hash table. Fix documentation strings.
2240 * scripts/targets/INTERMEDIATE: Reverse order of files
2241 passed to expected `rm' command.
2243 2002-07-10 Greg McGary <greg@mcgary.org>
2245 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
2246 * hash.c: New file, taken from id-utils.
2247 * hash.h: New file, taken from id-utils.

2257 (init_hash_files): New function decl.
2259 * ar.c (ar_name): Delay call to strlen until needed.
2260 * main.c (initialize_global_hash_tables): New function.
2261 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
2262 * misc.c (remove_comments): Pass char constants to find_char_unquote.
2263 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
2265 * dir.c (hash.h): New #include.
2266 (struct directory_contents) [next, files]: Remove members.

2280 (file_impossible_p): Likewise.
2281 (print_dir_data_base): Likewise.
2282 (open_dirstream): Likewise.
2283 (read_dirstream): Likewise.
2284 (hash_init_directories): New function.

2287 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
2288 (files): Change type to `struct hash_table'.
2289 (lookup_file): Use new hash table package.
2290 (enter_file): Likewise.
2291 (remove_intermediates): Likewise.
2292 (snap_deps): Likewise.
2293 (print_file_data_base): Likewise.
2295 * function.c
2296 (function_table_entry_hash_1, function_table_entry_hash_2,
2297 function_table_entry_hash_cmp): New functions.
2298 (lookup_function): Remove `table' argument.
2299 Use new hash table package.
2300 (struct a_word) [chain, length]: New members.
2301 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
2302 (struct a_pattern): New struct.
2303 (func_filter_filterout): Pass through patterns noting boundaries
2304 and '%', if present. Note a_word length. Use a hash table if
2305 arglists are large enough to justify cost.
2306 (function_table_init): Renamed from function_table.
2307 (function_table): Declare as `struct hash_table'.
2308 (FUNCTION_TABLE_ENTRIES): New constant.
2309 (hash_init_function_table): New function.
2311 * read.c (hash.h): New #include.
2312 (read_makefile): Pass char constants to find_char_unquote.
2313 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
2314 (uniquize_deps): Use hash table to efficiently identify duplicates.
2315 (find_char_unquote): Accept two char-constant stop chars, rather
2316 than a string constant, avoiding zillions of calls to strchr.
2317 Tighten inner search loops to test only for desired delimiters.
2319 * variable.c (variable_hash_1, variable_hash_2,
2320 variable_hash_cmp): New functions.

2332 (target_environment): Likewise.
2333 (print_variable_set): Likewise.
2335 2002-07-10 Paul D. Smith <psmith@gnu.org>
2337 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2338 prerequisite list. A real SysV make will expand the entire
2339 prerequisites list _twice_: we don't do that as it's a big
2340 backward-compatibility problem. We only replace those specific
2341 variables.
2343 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2344 references left in the list of prerequisites. Check for .POSIX as
2345 we record targets, so we can disable non-POSIX behavior while
2346 reading makefiles as well as running them.
2347 (eval): Check the prerequisite list to see if we have anything
2348 that looks like a SysV prerequisite variable reference.
2350 2002-07-09 Paul D. Smith <psmith@gnu.org>
2352 * doc/make.texi (Prerequisite Types): Add a new section describing
2353 order-only prerequisites.
2355 * read.c (uniquize_deps): If we have the same file as both a
2356 normal and order-only prereq, get rid of the order-only prereq,
2357 since the normal one supersedes it.
2359 2002-07-08 Paul D. Smith <psmith@gnu.org>
2361 * AUTHORS: Added Greg McGary to the AUTHORS file.
2362 * NEWS: Blurbed order-only prerequisites.
2363 * file.c (print_file): Show order-only deps properly when printing
2364 the database.
2366 * maintMakefile: Add "update" targets for wget'ing the latest
2367 versions of various external files. Taken from Makefile.maint in
2368 autoconf, etc.
2370 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2371 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2373 2002-07-07 Paul D. Smith <psmith@gnu.org>
2375 * po/*.po: Remove. We'll use wget to retrieve them at release
2376 time.
2378 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2379 rather than a shell you get an exception. Make sure we look up
2380 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2382 * remake.c (notice_finished_file): Fix handling of -t flag.
2383 Patch provided by Henning Makholm <henning@makholm.net>.
2385 * implicit.c (pattern_search): Some systems apparently run short
2386 of stack space, and using alloca() in this function caused an
2387 overrun. I modified it to use xmalloc() on the two variables
2388 which seemed like they might get large. Fixes Bug #476.
2390 * main.c (print_version): Update copyright notice to conform with
2391 GNU standards.
2392 (print_usage): Update help output.
2394 * function.c (func_eval): Create a new make function, $(eval
2395 ...). Expand the arguments, put them into a buffer, then invoke
2396 eval_buffer() on the resulting string.
2397 (func_quote): Create a new function, $(quote VARNAME). Inserts
2398 the value of the variable VARNAME without expanding it any
2399 further.
2401 * read.c (struct ebuffer): Change the linebuffer structure to an
2402 "eval buffer", which can be either a file or a buffer.
2403 (eval_makefile): Move the code in the old read_makefile() which
2404 located a makefile into here: create a struct ebuffer with that
2405 information. Have it invoke the new function eval() with that
2406 ebuffer.
2407 (eval_buffer): Create a new function that creates a struct ebuffer
2408 that holds a string buffer instead of a file. Have it invoke
2409 eval() with that ebuffer.
2410 (eval): New function that contains the guts of the old
2411 read_makefile() function: this function parses makefiles. Obtains
2412 data to parse from the provided ebuffer. Some modifications to
2413 make the flow of the function cleaner and clearer. Still could
2414 use some work here...
2415 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2416 contents of the define/endef variable from the ebuffer.
2417 (readstring): Read the next line from a string-style ebuffer.
2418 (readline): Read the next line from an ebuffer. If it's a string
2419 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2420 from the file.
2422 * dep.h (eval_buffer): Prototype eval_buffer();
2424 * variable.c (do_variable_definition): Make sure that all
2425 non-target-specific variables are registered in the global set.
2426 If we're invoked from an $(eval ...) we might be inside a $(call
2427 ...) or other function which has pushed a variable scope; we still
2428 want to define our variables from evaluated makefile code in the
2429 global scope.
2431 2002-07-03 Greg McGary <greg@mcgary.org>
2433 * dep.h (struct dep) [ignore_mtime]: New member.
2434 [changed]: convert to a bitfield.
2435 * implicit.c (pattern_search): Zero ignore_mtime.
2436 * main.c (main, handle_non_switch_argument): Likewise.
2437 * rule.c (convert_suffix_rule): Likewise.
2438 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2439 (read_makefile): Parse '|' in prerequisite list.
2440 (uniquize_deps): Consider ignore_mtime when comparing deps.
2441 * remake.c (update_file_1, check_dep): Don't force remake for
2442 dependencies that have d->ignore_mtime.
2443 * commands.c (FILE_LIST_SEPARATOR): New constant.
2444 (set_file_variables): Don't include a
2445 prerequisite in $+, $^ or $? if d->ignore_mtime.
2446 Define $|.
2448 2002-06-18 Paul D. Smith <psmith@gnu.org>
2450 * make.texinfo: Updates for next revision. New date/rev/etc.
2451 Recreate all Info menus. Change license on the manual to the GNU
2452 Free Documentation License. A number of typos.
2453 (Variables Simplify): Don't use "-" before it's defined.
2454 (Automatic Prerequisites): Rewrite the target example to work
2455 properly if the compile fails. Remove incorrect comments about
2456 how "set -e" behaves.
2457 (Text Functions): Move the "word", "wordlist", "words", and
2458 "firstword" functions here, from "File Name Functions".
2459 * make-stds.texi: Update from latest GNU version.
2460 * fdl.texi: (created) Import the latest GNU version.
2462 2002-06-06 Paul D. Smith <psmith@gnu.org>
2464 * variable.c (do_variable_definition): New function: extract the
2465 part of try_variable_definition() that actually sets the value
2466 into a separate function.
2467 (try_variable_definition): Call do_variable_definition() after
2468 parsing the variable definition string.
2469 (define_variable_in_set): Make the name argument const.
2471 * variable.h (enum variable_flavor): Make public.
2472 (do_variable_definition): Create prototype.
2474 * read.c (read_all_makefiles): Create a new built-in variable,
2475 MAKEFILE_LIST.
2476 (read_makefile): Add each makefile read in to this variable value.
2478 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2480 * Makefile.DOS.template: Tweak according to changes in the
2481 distribution. Add back the dependencies of *.o files.
2483 * configh.dos.template: Synchronize with config.h.in.
2485 2002-05-09 Paul D. Smith <psmith@gnu.org>
2487 * file.c (file_timestamp_now): Use K&R function declaration.
2489 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2490 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2491 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2492 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2493 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2494 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2495 nlist.n_name is a pointer rather than an array.
2497 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2498 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2499 * configure.in: Use it instead of the old version.
2501 * main.c (main): Prefer setvbuf() to setlinebuf().
2503 2002-05-08 Paul D. Smith <psmith@gnu.org>
2505 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2506 (loadavg_LDADD): Ditto.
2508 2002-04-29 Paul D. Smith <psmith@gnu.org>
2510 * expand.c (recursively_expand_for_file): Rename
2511 recursively_expand() to recursively_expand_for_file() and provide
2512 an extra argument, struct file. If the argument is provided, set
2513 the variable scope to that of the file before expanding.
2514 * variable.h (recursively_expand): Make this a macro that invokes
2515 recursively_expand_for_file() with a NULL file pointer.
2516 * variable.c (target_environment): Call the renamed function and
2517 provide the current file context.
2518 Fixes Debian bug #144306.
2520 2002-04-28 Paul D. Smith <psmith@gnu.org>
2522 Allow $(call ...) user-defined variables to be self-referencing
2523 without throwing an error. Allows implementation of transitive
2524 closures, among other possibly useful things.
2525 Requested by: Philip Guenther <guenther@sendmail.com>
2527 * variable.h (struct variable): Add a new field: exp_count, and
2528 new macros to hold its size and maximum value.
2529 (warn_undefined): Make this a macro.
2530 * variable.c (define_variable_in_set): Initialize it.
2531 * expand.c (recursively_expand): If we detect recursive expansion
2532 of a variable, check the exp_count field. If it's greater than 0
2533 allow the recursion and decrement the count.
2534 (warn_undefined): Remove this (now a macro in variable.h).
2535 * function.c (func_call): Before we expand the user-defined
2536 function, modify its exp_count field to contain the maximum
2537 number of recursive calls we'll allow. After the call, reset it
2538 to 0.
2540 2002-04-21 Paul D. Smith <psmith@gnu.org>
2542 Modified to use latest autoconf (2.53), automake (1.6.1), and
2543 gettext (0.11.1). We're using gettext's new "external" support,
2544 to avoid including libintl source with GNU make.
2546 * README.cvs: New file. Explain how to build GNU make from CVS.
2548 * configure.in: Modify checking for the system glob library.
2549 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2550 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2551 etc. will manage it correctly). Set an automake conditional
2552 USE_LOCAL_GLOB to decide whether to compile the glob library.
2554 * getloadavg.c (main): Include make.h in the "TEST" program to
2555 avoid warnings.
2557 * Makefile.am: Remove special rules for loadavg. Replace them
2558 with Automake capabilities for building extra programs.
2560 * signame.c: This file does nothing if the system provide
2561 strsignal(). If not, it implements strsignal(). If the system
2562 doesn't define sys_siglist, then we make our own; otherwise we use
2563 the system version.
2564 * signame.h: Removed.
2566 * main.c (main): No need to invoke signame_init(). Update copyright.
2568 * ABOUT-NLS: Removed.
2569 * gettext.c: Removed.
2570 * gettext.h: Get a simplified copy from the gettext package.
2571 * po/*: Created.
2572 * i18n/*.po: Moved to po/.
2573 * i18n/: Removed.
2575 * config/*: Created. Contains package configuration helper files.
2576 * config.guess, config.sub: Moved to config directory.
2578 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2579 Rework to use new-style autoconf features. Use the "external"
2580 mode for gettext. Make the build.sh config file conditional on
2581 whether build.sh.in exists, to avoid autoconf errors.
2582 * acinclude.m4: Removed almost all macros as being obsolete.
2583 Rewrote remaining macros to use AC_DEFINE.
2584 * acconfig.h: Removed.
2586 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2587 conditional to handle customs support. Remove special handling
2588 for i18n features.
2590 2002-04-20 Paul D. Smith <psmith@gnu.org>
2592 * function.c (func_call): Don't mark the argument variables $1,
2593 etc. as recursive. They've already been fully expanded so
2594 there's no need to do it again, and doing so strips escaped $'s.
2595 Reported by Sebastian Glita <glseba@yahoo.com>.
2597 * remake.c (notice_finished_file): Walk through double-colon
2598 entries via the prev field, not the next field!
2599 Reported by Greg McGary <greg@mcgary.org>.
2601 * main.c (main): If the user specifies -q and asks for a specific
2602 target which is a makefile, we got an assert. In that case it
2603 turns out we should continue normally instead.
2605 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2607 * i18n/he.po: Installed a new translation.
2609 2002-01-07 Paul D. Smith <psmith@gnu.org>
2611 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2613 2001-12-04 Paul D. Smith <psmith@gnu.org>
2615 * i18n/ja.po: Installed an updated translation.
2617 2001-09-06 Paul Eggert <eggert@twinsun.com>
2619 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2620 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2622 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2623 are available.
2624 (main): Get rid of any avoidable limit on stack size.
2626 2001-09-04 Paul D. Smith <psmith@gnu.org>
2628 * i18n/da.po: Installed an updated translation.
2630 2001-08-03 Paul D. Smith <psmith@gnu.org>
2632 * i18n/fr.po: Installed an updated translation.
2633 Resolves Debian bug #106720.
2635 2001-06-13 Paul D. Smith <psmith@gnu.org>
2637 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2638 translation.
2640 2001-06-11 Paul D. Smith <psmith@gnu.org>
2642 * i18n/ko.po: Installed a new translation.
2644 2001-05-06 Paul D. Smith <psmith@gnu.org>
2646 Modify the EINTR handling.
2648 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2649 the way in which we manage the file descriptor/signal handler race
2650 trap to be more efficient.
2652 2001-05-06 Paul Eggert <eggert@twinsun.com>
2654 Restart almost all system calls that are interrupted, instead
2655 of worrying about EINTR. The lone exception is the read() for
2656 job tokens.
2658 * configure.in (HAVE_SA_RESTART): New macro.
2659 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2660 * main.c (main): Use SA_RESTART instead of the old,
2661 nonstandard SA_INTERRUPT.
2663 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2664 * main.c (bsd_signal): New function or macro,
2665 if the implementation doesn't supply it.
2666 (The bsd_signal function will be in POSIX 1003.1-200x.)
2667 (HANDLESIG): Remove.
2668 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2670 * make.h (EINTR_SET): Remove.
2671 (SA_RESTART): New macro.
2673 * arscan.c (ar_member_touch): Don't worry about EINTR.
2674 * function.c (func_shell): Likewise.
2675 * job.c (reap_children, free_child, new_job): Likewise.
2676 * main.c (main): Likewise.
2677 * remake.c (touch_file, name_mtime): Likewise.
2679 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2680 if fstat failed with errno!=EINTR, the error was ignored.
2682 * job.c (set_child_handler_action_flags): New function.
2683 (new_job): Use it to temporarily clear the SIGCHLD action flags
2684 while reading the token.
2686 2001-05-02 Paul D. Smith <psmith@gnu.org>
2688 * job.c (start_job_command): Don't add define/endef per-line flags
2689 to the top-level flags setting.
2691 2001-04-03 Paul D. Smith <psmith@gnu.org>
2693 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2694 bit on error, so check for odd return values, not non-0 return
2695 values.
2696 (VMS_get_member_info): Calculate the timezone differences correctly.
2697 Reported by John Fowler <jfowler@nyx.net>.
2700 2001-03-14 Paul D. Smith <psmith@gnu.org>
2702 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2703 value before invoking define_variable().
2704 Reported by John Fowler <jfowler@nyx.net>.
2706 2001-02-07 Paul D. Smith <psmith@gnu.org>
2708 * read.c (record_target_var): If we reset the variable due to a
2709 command-line variable setting overriding it, turn off the "append"
2710 flag.
2712 2001-01-17 Paul D. Smith <psmith@gnu.org>
2714 * variable.c (lookup_variable) [VMS]: When getting values from the
2715 environment, allocate enough space for the _value_ plus escapes,
2716 not enough space for the name plus escapes :-/.
2717 Reported by John Fowler <jfowler@nyx.net>.
2719 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2720 warnings that make generates, so it doesn't look like an error.
2721 Reported by Karl Berry <karl@gnu.org>.
2724 Fix for PR/2020: Rework appended target-specific variables. I'm
2725 fairly confident this algorithm is finally correct.
2727 * expand.c (allocated_variable_append): Rewrite. Instead of
2728 expanding each appended variable then adding all the expanded
2729 strings together, we append all the unexpanded values going up
2730 through the variable set contexts, then expand the final result.
2731 This behaves just like non-target-specific appended variable
2732 values, while the old way didn't in various corner cases.
2733 (variable_append): New function: recursively append the unexpanded
2734 value of a variable, walking from the outermost variable scope to
2735 the innermost.
2736 * variable.c (lookup_variable): Remove the code that looked up the
2737 variable set list if the found variable was "append". We don't
2738 need this anymore.
2739 (lookup_variable_in_set): Make this non-static so we can use it
2740 elsewhere.
2741 (try_variable_definition): Use lookup_variable_in_set() rather
2742 than faking out current_variable_set_list by hand (cleanup).
2743 * variable.h: Add a prototype for the now non-static
2744 lookup_variable_in_set().
2746 2000-11-17 Paul D. Smith <psmith@gnu.org>
2748 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2749 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2750 before throwing a fit.
2752 2000-11-17 Paul D. Smith <psmith@gnu.org>
2754 * read.c (readline): CRLF calculations had a hole, if you hit the
2755 buffer grow scenario just right. Reworked the algorithm to avoid
2756 the need for len or lastlen at all. Problem description with
2757 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2759 2000-10-24 Paul D. Smith <psmith@gnu.org>
2761 * gettext.c (SWAP): Declare this with the prototype, otherwise
2762 some systems don't work (non-32-bit? Reported for Cray T3E).
2763 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2765 2000-10-05 Paul D. Smith <psmith@gnu.org>
2767 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2768 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2770 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2772 2000-09-22 Paul D. Smith <psmith@gnu.org>
2774 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2775 parts of the real gettext.h here, and we expect to really include
2776 the real gettext.h later. If we keep this #define, it's ignored.
2778 2000-09-21 Paul D. Smith <psmith@gnu.org>
2780 * main.c (log_working_directory): Rework the text to use complete
2781 sentences, to make life simpler for the translators.
2783 2000-08-29 Paul D. Smith <psmith@gnu.org>
2785 * file.c (remove_intermediates): Print a debug message before we
2786 remove intermediate files, so the user (if she uses -d) knows
2787 what's going on.
2789 2000-08-21 Paul D. Smith <psmith@gnu.org>
2791 * variable.c (try_variable_definition): Change how we handle
2792 target-specific append variable defns: instead of just setting the
2793 value, expand it as an append _but_ only within the current
2794 target's context. Otherwise we lose all but the last value if the
2795 variable is appended more than once within the current target
2796 context. Fixes PR/1831.
2798 2000-08-16 Paul D. Smith <psmith@gnu.org>
2800 * function.c (func_shell): Nul-terminate the buffer before
2801 printing an exec error message (just in case it's not!).
2802 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2804 2000-07-25 Paul D. Smith <psmith@gnu.org>
2806 * job.c (construct_command_argv_internal): Add "~" to the list of
2807 sh_chars[] which disallow optimizing out the shell call.
2809 2000-07-23 Paul Eggert <eggert@twinsun.com>
2811 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2812 supersedes --disable-nsec-timestamps.
2813 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2814 * README: Remove --disable-nsec-timestamps.
2816 * filedef.h (struct file.low_resolution_time): New member.
2817 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2818 * remake.c (update_file_1):
2819 Avoid spurious rebuilds due to low resolution time stamps,
2820 generalizing the earlier code that applied only to archive members.
2821 (f_mtime): Archive members always have low resolution time stamps.
2823 * configure.in: Remove --disable-nsec-timestamps, as this has
2824 been superseded by .LOW_RESOLUTION_TIME.
2826 2000-07-23 Paul Eggert <eggert@twinsun.com>
2828 * configure.in (enable_nsec_timestamps): Renamed from
2829 make_cv_nsec_timestamps, since enable/disable options
2830 shouldn't be cached.
2832 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2833 and Paul Eggert <eggert@twinsun.com>
2835 * file.c (file_timestamp_now):
2836 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2837 so that clock_gettime is not linked unless needed.
2839 * filedef.h (FILE_TIMESTAMP_HI_RES):
2840 Remove definition; "configure" now does this.
2842 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2843 to before high resolution file timestamp check,
2844 since that check now uses uintmax_t.
2845 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2846 high resolution file timestamps.
2847 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2848 so that we don't link in clock_gettime unnecessarily.
2850 2000-07-17 Paul D. Smith <psmith@gnu.org>
2852 * i18n/ja.po: New version of the translation file.
2854 2000-07-07 Paul D. Smith <psmith@gnu.org>
2856 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2857 the offset calculation.
2858 (name_mtime): Replace EINTR test with EINTR_SET macro.
2860 2000-07-07 Paul Eggert <eggert@twinsun.com>
2862 Fix for PR/1811:
2864 * remake.c (update_file_1):
2865 Avoid spurious rebuilds of archive members due to their
2866 timestamp resolution being only one second.
2867 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2868 the clock's resolution being lower than file timestamps'.
2869 When warning about future timestamps, report only the discrepancy,
2870 not the absolute value of the timestamp and the current time.
2872 * file.c (file_timestamp_now): New arg RESOLUTION.
2873 * filedef.h (file_timestamp_now): Likewise.
2874 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2876 2000-07-05 Paul D. Smith <psmith@gnu.org>
2878 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2879 to listp. Fixes PR/1793.
2881 2000-06-26 Paul Eggert <eggert@twinsun.com>
2883 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2885 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2887 * remake.c (f_mtime): Remove unused var memtime.
2889 2000-06-25 Martin Buchholz <martin@xemacs.org>
2891 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2892 Ran spell-check on make.texinfo.
2894 2000-06-23 Paul D. Smith <psmith@gnu.org>
2896 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2897 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2898 * make.h: Define these macros.
2900 * Version 3.79.1 released.
2902 * configure.in: Add a new option, --disable-nsec-timestamps, to
2903 avoid using sub-second timestamps on systems that support it. It
2904 can lead to problems, e.g. if your makefile relies on "cp -p".
2905 * README.template: Document the issue with "cp -p".
2907 * config.guess, config.sub: Updated.
