64 that don't have extended grep.
65 (cvsclean): Use $(PERL) instead of perl.
67 2006-04-09 Paul D. Smith <psmith@gnu.org>
69 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
71 * expand.c, implicit.c, main.c, read.c: Rename variables so that
72 inner-scope variables don't mask outer-scope variables.
74 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
75 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
76 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
77 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
78 values from memory allocation functions: they return void* and so
79 don't need to be cast. Also remove (char *) casts of arguments to
80 xrealloc().
82 * configure.in: Remove checks for memcpy/memmove/strchr.
84 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

94 2006-04-06 Paul D. Smith <psmith@gnu.org>
96 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
97 require an ISO C 1989 standard compiler and runtime library.

113 Version 3.81 released.
115 * NEWS: Updated for 3.81.
117 * README.cvs: Mention that vpath builds are not supported out of
118 CVS. Fixes Savannah bug #16236.
119 Remove update of make.texi from the list of things to do; we use
120 version.texi now.
122 2006-03-26 Paul D. Smith <psmith@gnu.org>
124 * doc/make.texi: Clean up licensing. Use @copying and version.texi
125 support from automake, as described in the Texinfo manual.
127 2006-03-25 Eli Zaretskii <eliz@gnu.org>
129 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
130 with lastslash, since the latter points to filename, not to
131 target.
132 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
133 Declare and define sh_chars_sh[].
135 2006-03-23 Paul D. Smith <psmith@gnu.org>
137 * configure.in: Look for build.sh.in in $srcdir so it will be
138 built for remote configurations as well.
140 * Makefile.am: Make sure to clean up build.sh during distclean.
141 Fixes Savannah bug #16166.
143 * misc.c (log_access): Takes a const char *.

145 Both fixes for Savannah bug #16170.
147 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
149 * implicit.c (pattern_search): Call set_file_variables only
150 if we have prerequisites that need second expansion. Fixes
151 Savannah bug #16140.
153 2006-03-19 Paul D. Smith <psmith@gnu.org>

156 memory on hosts that don't support it directly.
158 * README.cvs: Add information on steps for making a release (to
159 make sure I don't forget any).
161 * main.c (clean_jobserver): Move jobserver cleanup code into a new
162 function.
163 (die): Cleanup code was removed from here; call the new function.
164 (main): If we are re-execing, clean up the jobserver first so we
165 don't leak file descriptors.
166 Fix bug reported by Craig Fithian <craig.fithian@citigroup.com>.
168 2006-03-17 Paul D. Smith <psmith@gnu.org>
170 * maintMakefile (do-po-update): Rewrite this rule to clean up and
171 allow multiple concurrent runs.
172 Patch from Joseph Myers <joseph@codesourcery.com>
174 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
176 * dep.h (struct dep): Add the stem field.
177 * misc.c (alloc_dep, free_dep): New functions.
178 (copy_dep_chain): Copy stem.
179 (free_dep_chain): Use free_dep.
180 * read.c (record_files): Store stem in the dependency line.
181 * file.c (expand_deps): Use stem stored in the dependency line. Use
182 free_dep_chain instead of free_ns_chain.
183 * implicit.c (pattern_search): Use alloc_dep and free_dep.
184 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
185 * main.c (main, handle_non_switch_argument): Ditto.
186 * remake.c (check_dep): Ditto.
187 * rule.c (convert_suffix_rule, freerule): Ditto.
189 2006-03-14 Paul D. Smith <psmith@gnu.org>
191 * expand.c (variable_append): Instead of appending everything then
192 expanding the result, we expand (or not, if it's simple) each part
193 as we add it.
194 (allocated_variable_append): Don't expand the final result.
195 Fixes Savannah bug #15913.
197 2006-03-09 Paul Smith <psmith@gnu.org>
199 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
200 listed non-existent files as changed. Turns out there's a bug in
201 the Linux kernel builds which means that this change causes
202 everything to rebuild every time. We will re-introduce this fix
203 in the next release, to give them time to fix their build system.
204 Fixes Savannah bug #16002.
205 Introduces Savannah bug #16051.
207 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
208 we *don't* find UNIX "/".
209 Reported by David Ergo <david.ergo@alterface.com>
211 2006-03-04 Eli Zaretskii <eliz@gnu.org>
213 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
214 locator function find_and_set_default_shell if SHELL came from the
215 command line.
217 2006-02-20 Paul D. Smith <psmith@gnu.org>
219 * variable.c (merge_variable_set_lists): It's legal for *setlist0
220 to be null; don't core in that case.
222 2006-02-19 Paul D. Smith <psmith@gnu.org>
224 * commands.c (set_file_variables): Realloc, not malloc, the static
225 string values to avoid memory leaks.
227 * expand.c (recursively_expand_for_file): Only set reading_file to
228 an initialized value.
230 * implicit.c (pattern_search): We need to make a copy of the stem
231 if we get it from an intermediate dep, since those get freed.
233 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
234 begin with ".".
235 (enter_file) [VMS]: Ditto.
236 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
238 2006-02-24 Eli Zaretskii <eliz@gnu.org>
240 * job.c (construct_command_argv_internal): Fix last change.
242 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
243 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
244 the calls to _beginthreadex.
246 * expand.c (recursively_expand_for_file): Initialize `save' to
247 prevent compiler warnings.
249 2006-02-18 Eli Zaretskii <eliz@gnu.org>
251 * job.c (construct_command_argv_internal): Don't create a temporary
252 script/batch file if we are under -n. Call _setmode to switch the
253 script file stream to text mode.
255 2006-02-17 Paul D. Smith <psmith@gnu.org>
257 * variable.c (merge_variable_set_lists): Don't try to merge the
258 global_setlist. Not only is this useless, but it can lead to
259 circularities in the linked list, if global_setlist->next in one
260 list gets set to point to another list which also ends in
261 global_setlist.
262 Fixes Savannah bug #15757.
264 2006-02-15 Paul D. Smith <psmith@gnu.org>
266 Fix for Savannah bug #106.
268 * expand.c (expanding_var): Keep track of which variable we're
269 expanding. If no variable is being expanded, it's the same as
270 reading_file.
271 * make.h (expanding_var): Declare it.
272 * expand.c (recursively_expand_for_file): Set expanding_var to the
273 current variable we're expanding, unless there's no file info in
274 it (could happen if it comes from the command line or a default
275 variable). Restore it before we exit.
276 * expand.c (variable_expand_string): Use the expanding_var file
277 info instead of the reading_file info.
278 * function.c (check_numeric): Ditto.
279 (func_word): Ditto.
280 (func_wordlist): Ditto.
281 (func_error): Ditto.
282 (expand_builtin_function): Ditto.
283 (handle_function): Ditto.
285 2006-02-14 Paul D. Smith <psmith@gnu.org>
287 * read.c (eval): Even if the included filenames expands to the
288 empty string we still need to free the allocated buffer.
290 * implicit.c (pattern_search): If we allocated a variable set for
291 an impossible file, free it.
292 * variable.c (free_variable_set): New function.
293 * variable.h: Declare it.
295 * read.c (read_all_makefiles): Makefile names are kept in the
296 strcache, so there's never any need to alloc/free them.
297 (eval): Ditto.
299 * main.c (main): Add "archives" to the .FEATURES variable if
300 archive support is enabled.
301 * doc/make.texi (Special Variables): Document it.
303 2006-02-13 Paul D. Smith <psmith@gnu.org>
305 * implicit.c (pattern_search): Add checking for DOS pathnames to
306 the pattern rule target LASTSLASH manipulation.
307 Fixes Savannah bug #11183.
309 2006-02-11 Paul D. Smith <psmith@gnu.org>
311 * (ALL FILES): Updated copyright and license notices.
313 2006-02-10 Paul D. Smith <psmith@gnu.org>
315 A new internal capability: the string cache is a read-only cache
316 of strings, with a hash table interface for fast lookup. Nothing
317 in the cache will ever be freed, so there's no need for reference
318 counting, etc. This is the beginning of a full solution for
319 Savannah bug #15182, but for now we only store makefile names here.
321 * strcache.c: New file. Implement a read-only string cache.
322 * make.h: Add prototypes for new functions.
323 * main.c (initialize_global_hash_tables): Initialize the string cache.
324 (print_data_base): Print string cache stats.
325 * read.c (eval_makefile): Use the string cache to store makefile
326 names. Rewrite the string allocation to be sure we free everything.
328 2006-02-10 Eli Zaretskii <eliz@gnu.org>
330 * dir.c (dir_contents_file_exists_p): Don't opendir if the
331 directory time stamp didn't change, except on FAT filesystems.
332 Suggested by J. David Bryan <jdbryan@acm.org>.
334 2006-02-09 Paul D. Smith <psmith@gnu.org>
336 * function.c (func_or): Implement a short-circuiting OR function.
337 (func_and): Implement a short-circuiting AND function.
338 (function_table_init): Update the table with the new functions.
339 * doc/make.texi (Conditional Functions): Changed the "if" section
340 to one on general conditional functions. Added documentation for
341 $(and ...) and $(or ...) functions.
342 * NEWS: Note new $(and ...) and $(or ...) functions.
344 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
346 * job.h (struct child): Add the dontcare bitfield.
347 * job.c (new_job): Cache dontcare flag.
348 * job.c (reap_children): Use cached dontcare flag instead of the
349 one in struct file. Fixes Savannah bug #15641.
351 2006-02-06 Paul D. Smith <psmith@gnu.org>
353 * vpath.c (selective_vpath_search): If the file we find has a
354 timestamp from -o or -W, use that instead of the real time.
355 * remake.c (f_mtime): If the mtime is a special token from -o or
356 -W, don't overwrite it with the real mtime.
357 Fixes Savannah bug #15341.
359 Updates from Markus Mauhart <qwe123@chello.at>:
361 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
362 (process_signal, process_last_err, process_exit_code): Manage
363 invalid handle values.
364 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
365 manage invalid handles; remove them.
366 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
367 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
368 * README.cvs: Updates for building from CVS.
370 2006-02-05 Paul D. Smith <psmith@gnu.org>
372 * file.c (enter_file): Keep track of the last double_colon entry,
373 to avoid walking the list every time we want to add a new one.
374 Fixes Savannah bug #15533.
375 * filedef.h (struct file): Add a new LAST pointer.
377 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
378 the comparison. For 64-bits systems the result of the subtraction
379 might not fit into an int. Use comparison instead.
380 Fixes Savannah bug #15534.
382 * doc/make.texi: Update the chapter on writing commands to reflect
383 the changes made in 3.81 for backslash/newline and SHELL handling.
385 2006-02-01 Paul D. Smith <psmith@gnu.org>
387 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
388 variable st is not used when it's not initialized.
389 Patch from Eli Zaretskii <eliz@gnu.org>.
391 2006-01-31 Paul D. Smith <psmith@gnu.org>
393 * README.W32.template: Applied patch #4785 from
394 Markus Mauhart <qwe123@chello.at>.

401 * prepare_w32.bat: Remove this file from the distribution.
403 2006-01-21 Eli Zaretskii <eliz@gnu.org>
405 * remake.c (update_goal_chain): Set g->changed instead of
406 incrementing it, as it is only 8-bit wide, and could overflow if
407 many commands got started in update_file.
409 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
411 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
412 MAXIMUM_WAIT_OBJECTS.

420 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
421 are already more children than sub_proc.c can handle, behave as if
422 the load were too high.
423 (start_job_command): Fix a typo in error message when process_easy
424 fails.
426 2006-01-14 Eli Zaretskii <eliz@gnu.org>
428 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
429 the shell is not sh.exe.
431 * job.c (create_batch_file): Renamed from create_batch_filename;
432 all callers changed. Don't close the temporary file; return its
433 file descriptor instead. New arg FD allows to return the file
434 descriptor.
435 (construct_command_argv_internal): Use _fdopen instead of fopen to
436 open the batch file.
438 2006-01-04 Paul D. Smith <psmith@gnu.org>
440 * readme.vms: Updates for case-insensitive VMS file systems from
441 Hartmut Becker <Hartmut.Becker@hp.com>.
442 * dir.c (vms_hash): Ditto.
443 * vmsify.c (copyto): Ditto.
444 * vmsfunctions.c (readdir): Ditto.
446 * make.1: Add a section on the exit codes for make.
448 * doc/make.texi: A number of minor updates to the documentation.
450 2006-01-03 Paul D. Smith <psmith@gnu.org>
452 * remake.c (update_file_1): Mark a prerequisite changed if it
453 doesn't exist.
455 * read.c (eval): Be sure to strip off trailing whitespace from the
456 prerequisites list properly. Also, initialize all fields in
457 struct dep when creating a new one.

461 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
462 disable warnings for MSC.
463 Patch by Rob Tulloh <rtulloh@yahoo.com>.
465 2005-12-17 Eli Zaretskii <eliz@gnu.org>
467 * doc/make.texi (Execution): Add a footnote about changes in
468 handling of backslash-newline sequences. Mention the differences
469 on MS-DOS and MS-Windows.
471 * NEWS: More details about building the MinGW port and a pointer
472 to README.W32. Fix the section name that describes the new
473 backward-incompatible processing of backslash-newline sequences.
474 The special processing of SHELL set to "cmd" is only relevant to
475 MS-Windows, not MS-DOS.
477 2005-12-17 Eli Zaretskii <eliz@gnu.org>
479 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
480 to DWORD, to avoid compiler warnings.
481 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
482 use %ld in format, to avoid compiler warnings.
484 * doc/make.texi (Special Targets): Fix a typo.
485 (Appending): Fix cross-reference to Setting.
486 (Special Variables, Secondary Expansion, File Name Functions)
487 (Flavor Function, Pattern Match, Quick Reference): Ensure two
488 periods after a sentence.
489 (Execution): Add @: after "e.g.".
490 (Environment): Fix punctuation.
491 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
492 (Shell Function, Target-specific): Add @: after "vs."
494 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
496 * read.c (record_target_var): Initialize variable's export field
497 with v_default instead of leaving it "initialized" by whatever
498 garbage happened to be on the heap.
500 2005-12-12 Paul D. Smith <psmith@gnu.org>
502 * make.1: Fix some display errors and document all existing options.
503 Patch provided by Mike Frysinger <vapier@gentoo.org>.
505 2005-12-11 Paul D. Smith <psmith@gnu.org>
507 * implicit.c (pattern_search): If 2nd expansion is not set for
508 this implicit rule, replace the pattern with the stem directly,
509 and don't re-expand the variable list. Along with the other
510 .SECONDEXPANSION changes below, fixes bug #13781.
512 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
514 * implicit.c (pattern_search): Mark other files that this rule
515 builds as targets so that they are not treated as intermediates
516 by the pattern rule search algorithm. Fixes bug #13022.
518 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
520 * remake.c (notice_finished_file): Propagate the change of
521 modification time to all the double-colon entries only if

531 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
533 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
534 variable.
535 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
536 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
538 2005-10-26 Paul Smith <psmith@gnu.org>
540 * read.c (record_files): Don't set deps flags if there are no deps.
541 * maintMakefile: We only need to build the templates when we are
542 creating a distribution, so don't do it for "all".
544 2005-10-24 Paul D. Smith <psmith@gnu.org>
546 Make secondary expansion optional: its enabled by declaring the
547 special target .SECONDEXPANSION.
549 * NEWS: Update information on second expansion capabilities.
550 * doc/make.texi (Secondary Expansion): Document the
551 .SECONDEXPANSION special target and its behavior.
552 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
553 prerequisite list was found in a static pattern rule.
554 (free_dep_chain): Declare a prototype.
555 * file.c (parse_prereqs): New function: break out some complexity
556 from expand_deps().
557 (expand_deps): If we aren't doing second expansion, replace % with
558 the stem for static pattern rules. Call the new function.
559 * filedef.h (parse_prereqs): Declare a prototype.
560 * implicit.c (pattern_search): Initialize the new staticpattern
561 field.
562 * main.c (second_expansion): Declare a global variable to remember
563 if the special target has been seen. Initialize the new
564 staticpattern field for prerequisites.
565 * make.h: Extern for second_expansion.
566 * misc.c (free_dep_chain): New function: frees a struct dep list.
567 * read.c (read_all_makefiles): Initialize the staticpattern field.
568 (eval_makefile): Ditto.
569 (record_files): Check for the .SECONDEXPANSION target and set
570 second_expansion global if it's found.
571 Use the new free_dep_chain() instead of doing it by hand.
572 Set the staticpattern field for prereqs of static pattern targets.
574 2005-10-16 Paul D. Smith <psmith@gnu.org>
576 * main.c (main): Set CURDIR to be a file variable instead of a
577 default, so that values of CURDIR inherited from the environment
578 won't override the make value.
580 2005-09-26 Paul D. Smith <psmith@gnu.org>
582 * job.c (construct_command_argv_internal): If the line is empty
583 remember to free the temporary argv strings.
584 Fixes bug # 14527.
586 2005-09-16 Paul D. Smith <psmith@gnu.org>
588 * job.c (start_job_command): The noerror flag is a boolean (single
589 bit); set it appropriately.
590 Reported by Mark Eichin <eichin@metacarta.com>
592 2005-08-29 Paul D. Smith <psmith@gnu.org>
594 * function.c (func_error): On Windows, output from $(info ...)
595 seems to come in the wrong order. Try to force it with fflush().
597 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
599 * read.c (record_files): Move code that sets stem for static
600 pattern rules out of the if (!two_colon) condition so it is
601 also executed for two-colon rules. Fixes Savannah bug #13881.
603 2005-08-08 Paul D. Smith <psmith@gnu.org>
605 * make.h: Don't test that __STDC__ is non-0. Some compilers
606 (Windows for example) set it to 0 to denote "ISO C + extensions".
607 Fixes bug # 13594.
609 2005-08-07 Paul D. Smith <psmith@gnu.org>
611 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
612 conditional (slightly different version of a fix from Eli).
614 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
615 If make is running in parallel without -k and two jobs die in a
616 row, but not too close to each other, then make will quit without
617 waiting for the rest of the jobs to die.
619 * main.c (die): Don't reset err before calling reap_children() the
620 second time: we still want it to be in the error condition.
621 * job.c (reap_children): Use a static variable, rather than err,
622 to control whether or not the error message should be printed.
624 2005-08-06 Eli Zaretskii <eliz@gnu.org>
626 * w32/subproc/sub_proc.c: Include signal.h.
627 (process_pipe_io, process_file_io): Pass a pointer to a local
628 DWORD variable to GetExitCodeProcess. If the exit code is
629 CONTROL_C_EXIT, put SIGINT into pproc->signal.
631 * job.c [WINDOWS32]: Include windows.h.
632 (main_thread) [WINDOWS32]: New global variable.
633 (reap_children) [WINDOWS32]: Get the handle for the main thread
634 and store it in main_thread.
636 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
637 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
638 doing anything else. When we are done, close the main thread
639 handle and exit with status 130.
641 2005-07-30 Eli Zaretskii <eliz@gnu.org>
643 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
644 pointer to fprintf.
646 * main.c (find_and_set_default_shell): If found a DOSish shell,
647 set sh_found and the value of default_shell, and report the
648 findings in debug mode.
650 * job.c (construct_command_argv_internal): Check unixy_shell, not
651 no_default_sh_exe, to decide whether to use Unixy or DOSish
652 builtin commands.
654 * README.W32: Update with info about the MinGW build.
656 * build_w32.bat: Support MinGW.
658 * w32/subproc/build.bat: Likewise.
660 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
661 printing DWORD args.
663 * function.c (windows32_openpipe): Fix format strings for printing
664 DWORD args.
666 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
667 'reap_mode'.
668 (start_job_command): Fix format string for printing the result of
669 process_easy.
670 (start_job_command) [WINDOWS32]: Do not define.
671 (exec_command): Fix format string for printing HANDLE args.
673 * main.c (handle_runtime_exceptions): Fix sprintf format strings
674 to avoid compiler warnings.
675 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
676 (Note: some of these fixes were submitted independently by J. Grant)
678 2005-07-30 J. Grant <jg@jguk.org>
680 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
681 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
682 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
684 2005-07-15 Paul Smith <psmith@gnu.org>
686 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
687 we don't have a POSIX shell, then revert to the old
688 backslash-newline behavior (where they are stripped).
689 Fixes bug #13665.
691 2005-07-08 Paul D. Smith <psmith@gnu.org>
693 * config.h.W32.template: Reorder to match the standard config.h,
694 for easier comparisons.
695 From J. Grant <jg@jguk.org>
697 * maintMakefile: Remove .dep_segment before overwriting it, in
698 case it's not writable or noclobber is set.
699 * expand.c (variable_expand_string): Cast result of pointer
700 arithmetic to avoid a warning.
701 * main.c (switches): Add full-fledged final initializer.
703 2005-07-06 Paul D. Smith <psmith@gnu.org>
705 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
706 * signame.c (strsignal): If we found _sys_siglist[] or
707 __sys_siglist[] use those instead of sys_siglist[].
708 From Albert Chin <china@thewrittenword.com>
710 2005-07-04 Paul D. Smith <psmith@gnu.org>
712 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
713 globfree(); set up to use the GNU versions.
714 From Martin Zinser <zinser@zinser.no-ip.info>
716 2005-07-03 Paul D. Smith <psmith@gnu.org>
718 From J. Grant <jg@jguk.org>:
720 * README.W32.template: Update the Windows and tested MSVC versions.
721 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
722 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
723 * build_w32.bat: Ditto.
724 * w32/subproc/build.bat: Ditto.
726 2005-06-28 Paul D. Smith <psmith@gnu.org>
728 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
729 declaration was checked but not present.
731 2005-06-27 Paul D. Smith <psmith@gnu.org>
733 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
734 to unsigned long. Fixes Savannah bug #13550.
736 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
737 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
738 Fixes Savannah bug #13551.
740 2005-06-26 Paul D. Smith <psmith@gnu.org>
742 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
743 it if ANSI_STRING is not set.
745 2005-06-25 Paul D. Smith <psmith@gnu.org>
747 * read.c (eval): If no filenames are passed to any of the
748 "include" variants, don't print an error.
749 * doc/make.texi (Include): Document this.
750 Fixes Savannah bug #1761.
752 * job.c (construct_command_argv_internal): Sanitize handling of
753 backslash/newline pairs according to POSIX: that is, keep the
754 backslash-newline in the command script, but remove a following
755 TAB character, if present. In the fast path, make sure that the
756 behavior matches what the shell would do both inside and outside
757 of quotes. In the slow path, quote the backslash and put a
758 literal newline in the string.
759 Fixes Savannah bug #1332.
760 * doc/make.texi (Execution): Document the new behavior and give
761 some examples.
762 * NEWS: Make a note of the new behavior.
764 * make.h [WINDOWS32]: #include <direct.h>.
765 Fixes Savannah bug #13478.
767 * remake.c (name_mtime): If the stat() of a file fails and the -L
768 option was given and the file is a symlink, take the best mtime of
769 the symlink we can get as the mtime of the file and don't fail.
770 Fixes Savannah bug #13280.
772 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
773 If it's set, then don't stop on STOPCHARs or BLANKs if they're
774 inside a variable reference. Make this function static as it's
775 only used here.
776 (eval): Call find_char_unquote() with IGNOREVARS set when we're
777 parsing an unexpanded line looking for semicolons.
778 Fixes Savannah bug #1454.
779 * misc.c (remove_comments): Move this to read.c and make it static
780 as it's only used there. Call find_char_unquote() with new arg.
781 * make.h: Remove prototypes for find_char_unquote() and
782 remove_comments() since they're static now.
784 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
785 its export flag and obtain its value. When we need to re-exec,
786 increment the value and add it into the environment.
787 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
788 * NEWS: Mention MAKE_RESTARTS.
789 * main.c (always_make_set): New variable. Change the -B option to
790 set this one instead.
791 (main): When checking makefiles, only set always_make_flag if
792 always_make_set is set AND the restarts flag is 0. When building
793 normal targets, set it IFF always_make_set is set.
794 (main): Avoid infinite recursion with -W, too: only set what-if
795 files to NEW before we check makefiles if we've never restarted
796 before. If we have restarted, set what-if files to NEW _after_ we
797 check makefiles.
798 Fixes Savannah bug #7566:
800 2005-06-17 Paul D. Smith <psmith@gnu.org>
802 * default.c: Change VMS implicit rules to use $$$$ instead of $$
803 in the prerequisites list.
805 2005-06-12 Paul D. Smith <psmith@gnu.org>
807 Fix Savannah bug # 1328.
809 * configure.in: Check for atexit().
810 * misc.c (close_stdout): Test stdout to see if writes to it have
811 failed. If so, be sure to exit with a non-0 error code. Based on
812 code found in gnulib.
813 * make.h: Prototype.
814 * main.c (main): Install close_stdout() with atexit().
816 2005-06-10 Paul D. Smith <psmith@gnu.org>
818 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
820 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
821 headers; make vmsWaitForChildren() static; extern vmsify().
822 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
823 Don't create child_execute_job() here (it's in vmsjobs.c).
824 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
826 2005-06-09 Paul D. Smith <psmith@gnu.org>
828 * variable.c (push_new_variable_scope): File variables point
829 directly to the global_setlist variable. So, inserting a new
830 scope in front of that has no effect on those variables: they
831 don't go through current_variable_set_list. If we're pushing a
832 scope and the current scope is global, push it "the other way" so
833 that the new setlist is in the global_setlist variable, and
834 next points to a new setlist with the global variable set.
835 (pop_variable_scope): Properly undo a push with the new
836 semantics.
837 Fixes Savannah bug #11913.
839 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
841 * job.c (reap_children): Don't die of the command failed but
842 the dontcare flag is set. Fixes Savannah bug #13216.
844 * implicit.c (pattern_search): When creating a target from
845 an implicit rule match, lookup pattern target and set precious
846 flag in a newly created target. Fixes Savannah bug #13218.
848 2005-05-13 Paul D. Smith <psmith@gnu.org>
850 Implement "if... else if... endif" syntax.
852 * read.c (eval): Push all checks for conditional words ("ifeq",
853 "else", etc.) down into the conditional_line() function.
854 (conditional_line): Rework to allow "else if..." clause. New
855 return value -2 for lines which are not conditionals. The
856 ignoring flag can now also be 2, which means "already parsed a
857 true branch". If that value is seen no other branch of this
858 conditional can be considered true. In the else parsing if there
859 is extra text after the else, invoke conditional_line()
860 recursively to see if it's another conditional. If not, it's an
861 error. If so, raise the conditional value to this level instead
862 of creating a new conditional nesting level. Special check for
863 "else" and "endif", which aren't allowed on the "else" line.
864 * doc/make.texi (Conditional Syntax): Document the new syntax.
866 2005-05-09 Paul D. Smith <psmith@gnu.org>
868 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
869 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
870 recurses to the w32 directory, even on non-Windows systems. Use
871 the method suggested in the automake manual.
872 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
873 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
875 2005-05-07 Paul D. Smith <psmith@gnu.org>
877 * main.c (die): If we're dying with a fatal error (not that a
878 command has failed), write back any leftover tokens before we go.
880 * job.c (set_child_handler_action_flags): If there are jobs
881 waiting for the load to go down, set an alarm to go off in 1
882 second. This allows us to wake up from a potentially long-lasting
883 read() and start a new job if the load has gone down. Turn it off
884 after the read.
885 (job_noop): Dummy signal handler function.
886 (new_job): Invoke it with the new semantics.
888 * docs/make.texi: Document secondary expansion. Various cleanups
889 and random work.
891 2005-05-03 Paul D. Smith <psmith@gnu.org>
893 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
894 the targets which are to ultimately be made are called "goals";
895 see the GNU make manual. Also, MAKECMDGOALS, etc.
897 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
898 .DEFAULT_GOAL, and default_target_name to default_goal_name.
899 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
901 2005-05-02 Paul D. Smith <psmith@gnu.org>
903 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
904 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
905 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
906 functions to vmsjobs.c. #include it into jobs.c.
908 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
909 jobserver tokens. I found that this happens when an exported
910 recursive variable contains a $(shell ...) function reference: in
911 this situation we could "forget" to write back a token.
913 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
914 we have. It's not reliable to depend on the number of children in
915 our linked list so keep a separate count.
916 (new_job): Check jobserver_tokens rather than children &&
917 waiting_jobs. Increment jobserver_tokens when we get one.
918 (free_child): If jobserver_tokens is 0, internal error. If it's
919 >1, write a token back to the jobserver pipe (we don't write a
920 token for the "free" job). Decrement jobserver_tokens.
922 * main.c: Add variable master_job_slots.
923 (main): Set it to hold the number of jobs requested if we're the
924 master process, when using the jobserver.
925 (die): Sanity checks: first test jobserver_tokens to make sure
926 this process isn't holding any tokens we didn't write back.
927 Second, if master_job_slots is set count the tokens left in the
928 jobserver pipe and ensure it's the same as master_job_slots (- 1).
930 2005-04-24 Paul D. Smith <psmith@gnu.org>
932 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
933 with -l# can lose jobserver tokens, because waiting jobs are not
934 consulted properly when checking for the "free" token.
936 * job.c (free_child): Count waiting_jobs as having tokens.
937 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
938 handle jobs waiting for the load to drop.
940 2005-04-23 Paul D. Smith <psmith@gnu.org>
942 * main.c (main): Be careful to not core if a variable setting in
943 the environment doesn't contain an '='. This is illegal but can
944 happen in broken setups.
945 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
947 2005-04-12 Paul D. Smith <psmith@gnu.org>
949 The second expansion feature causes significant slowdown. Timing
950 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
951 read the makefile before the feature, to 11+s to do the same
952 operations after the feature. Additionally, memory usage
953 increased drastically. To fix this I added some intelligence that
954 avoids the overhead of the second expansion unless it's required.
956 * dep.h: Add a new boolean field, need_2nd_expansion.
958 * read.c (eval): When creating the struct dep for the target,
959 check if the name contains a "$"; if so set need_2nd_expansion to 1.
960 (record_files): If there's a "%" in a static pattern rule, it gets
961 converted to "$*" so set need_2nd_expansion to 1.
963 * file.c (expand_deps): Rework to be more efficient. Only perform
964 initialize_file_variables(), set_file_variables(), and
965 variable_expand_for_file() if the need_2nd_expansion is set.
967 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
968 (pattern_search): Ditto.
969 * main.c (handle_non_switch_argument): Ditto.
970 (main): Ditto.
971 * read.c (read_all_makefiles): Ditto.
972 (eval_makefile): Ditto.
974 2005-04-07 Paul D. Smith <psmith@gnu.org>
976 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
977 * variable.c (sync_Path_environment): Ditto.
978 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
980 * main.c (main): Define the .FEATURES variable.
981 * NEWS: Announce .FEATURES.
982 * doc/make.texi (Special Variables): Document .FEATURES.
984 * remake.c (check_dep): If a file is .PHONY, update it even if
985 it's marked intermediate. Fixes Savannah bug #12331.
987 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
989 * file.c (expand_deps): Factor out the second expansion and
990 prerequisite line parsing logic from snap_deps().
992 * file.c (snap_deps): Use expand_deps(). Expand and parse
993 prerequisites of the .SUFFIXES special target first. Fixes
994 Savannah bug #12320.
996 2005-03-13 Paul D. Smith <psmith@gnu.org>
998 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
999 Zaretskii.
1001 2005-03-11 Paul D. Smith <psmith@gnu.org>
1003 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1004 available, not undefined (from Earnie Boyd).
1006 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1008 * implicit.c (pattern_search): Mark an intermediate target as
1009 precious if it happened to be a prerequisite of some (other)
1010 target. Fixes Savannah bug #12267.
1012 2005-03-09 Paul D. Smith <psmith@gnu.org>
1014 * read.c (eval_makefile): Add alloca(0).
1015 (eval_buffer): Ditto.
1017 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1019 * main.c (main): Use o_file instead of o_default when defining
1020 the .DEFAULT_TARGET special variable.
1021 * read.c (eval): Use define_variable_global() instead of
1022 define_variable() when setting new value for the .DEFAULT_TARGET
1023 special variable. Fixes Savannah bug #12266.
1025 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1027 * imlicit.c (pattern_search): Mark files for which an implicit
1028 rule has been found as targets. Fixes Savannah bug #12202.
1030 2005-03-04 Paul D. Smith <psmith@gnu.org>
1032 * AUTHORS: Update.
1033 * doc/make.texi (Automatic Variables): Document $|.
1035 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1037 * read.c (record_files): Instead of substituting % with
1038 actual stem value in dependency list replace it with $*.
1039 This fixes stem triple expansion bug.
1041 * implicit.c (pattern_search): Copy stem to a separate
1042 buffer and make it a properly terminated string. Assign
1043 this buffer instead of STEM (which is not terminated) to
1044 f->stem. Instead of substituting % with actual stem value
1045 in dependency list replace it with $*. This fixes stem
1046 triple expansion bug.
1048 2005-03-01 Paul D. Smith <psmith@gnu.org>
1050 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1051 on Windows, as it takes a handle not a pid. Just exit.
1052 Fix from patch #3679, provided by Alessandro Vesely.
1054 * configure.in: Update check for sys_siglist[] from autoconf manual.
1055 * signame.c (strsignal): Update to use the new autoconf macro.
1057 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1059 * read.c (record_files): Add a check for the list of prerequisites
1060 of a static pattern rule being empty. Fixes Savannah bug #12180.
1062 2005-02-28 Paul D. Smith <psmith@gnu.org>
1064 * doc/make.texi (Text Functions): Update docs to allow the end
1065 ordinal for $(wordlist ...) to be 0.
1066 * function.c (func_wordlist): Fail if the start ordinal for
1067 $(wordlist ...) is <1. Matches documentation.
1068 Resolves Savannah support request #103195.
1070 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1071 previously we were stopping when !-q, exactly the opposite. This
1072 has been wrong since version 1.34, in 1994!
1073 (update_file): If we got an error don't break out to run more
1074 double-colon rules: just return immediately.
1075 Fixes Savannah bug #7144.
1077 2005-02-27 Paul D. Smith <psmith@gnu.org>
1079 * misc.c (end_of_token): Make argument const.
1080 * make.h: Update prototype.
1082 * function.c (abspath, func_realpath, func_abspath): Use
1083 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1084 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1085 * read.c (record_files): Ditto.
1086 * variable.c (do_variable_definition): Ditto.
1088 * function.c (func_error): Create a new function $(info ...) that
1089 simply prints the message to stdout with no extras.
1090 (function_table_init): Add new function to the table.
1091 * NEWS: Add $(info ...) reference.
1092 * doc/make.texi (Make Control Functions): Document it.
1094 New feature: if the system supports symbolic links, and the user
1095 provides the -L/--check-symlink-time flag, then use the latest
1096 mtime between the symlink(s) and the target file.
1098 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1099 readlink(). If both are available, define MAKE_SYMLINKS.
1100 * main.c: New variable: check_symlink_flag.
1101 (usage): Add a line for -L/--check-symlink-times to the help string.
1102 (switches): Add -L/--check-symlink-times command line argument.
1103 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1104 print a warning and disable it again.
1105 * make.h: Declare check_symlink_flag.
1106 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1107 if the file is a symlink then check each link in the chain and
1108 choose the NEWEST mtime we find as the mtime for the file. The
1109 newest mtime might be the file itself!
1110 * NEWS: Add information about this new feature.
1111 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1113 Avoid core dumps described in Savannah bug # 12124:
1115 * file.c: New variable snapped_deps remember whether we've run
1116 snap_deps().
1117 (snap_deps): Set it.
1118 * filedef.h: Extern it.
1119 * read.c (record_files): Check snapped_deps; if it's set then
1120 we're trying to eval a new target/prerequisite relationship from
1121 within a command script, which we don't support. Fatal.
1123 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1125 Implementation of the .DEFAULT_TARGET special variable.
1127 * read.c (eval): If necessary, update default_target_name when
1128 reading rules.
1129 * read.c (record_files): Update default_target_file if
1130 default_target_name has changed.
1131 * main.c (default_target_name): Define.
1132 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1133 default_target_name is set use default_target_file as a root
1134 target to make.
1135 * filedef.h (default_target_name): Declare.
1136 * dep.h (free_dep_chain):
1137 * misc.c (free_dep_chain): Change to operate on struct nameseq
1138 and change name to free_ns_chain.
1139 * file.c (snap_deps): Update to use free_ns_chain.
1141 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1143 Implementation of the second expansion in explicit rules,
1144 static pattern rules and implicit rules.
1146 * read.c (eval): Refrain from chopping up rule's dependencies.
1147 Store them in a struct dep as a single dependency line. Remove
1148 the code that implements SySV-style automatic variables.
1150 * read.c (record_files): Adjust the code that handles static
1151 pattern rules to expand all percents instead of only the first
1152 one. Reverse the order in which dependencies are stored so that
1153 when the second expansion reverses them again they appear in
1154 the makefile order (with some exceptions, see comments in
1155 the code). Remove the code that implements SySV-style automatic
1156 variables.
1158 * file.c (snap_deps): Implement the second expansion and chopping
1159 of dependency lines for explicit rules.
1161 * implicit.c (struct idep): Define an auxiliary data type to hold
1162 implicit rule's dependencies after stem substitution and
1163 expansion.
1165 * implicit.c (free_idep_chain): Implement.
1167 * implicit.c (get_next_word): Implement helper function for
1168 parsing implicit rule's dependency lines into words taking
1169 into account variable expansion requests. Used in the stem
1170 splitting code.
1172 * implicit.c (pattern_search): Implement the second expansion
1173 for implicit rules. Also fixes bug #12091.
1175 * commands.h (set_file_variables): Declare.
1176 * commands.c (set_file_variables): Remove static specifier.
1178 * dep.h (free_dep_chain): Declare.
1179 * misc.c (free_dep_chain): Implement.
1181 * variable.h (variable_expand_for_file): Declare.
1182 * expand.c (variable_expand_for_file): Remove static specifier.
1184 * make.h (strip_whitespace): Declare.
1185 * function.c (strip_whitespace): Remove static specifier.
1187 2005-02-26 Paul D. Smith <psmith@gnu.org>
1189 * main.c (main): Check for ferror() when reading makefiles from stdin.
1190 Apparently some shells in Windows don't close pipes properly and
1191 require this check.
1193 2005-02-24 Jonathan Grant <jg@jguk.org>
1195 * configure.in: Add MinGW configuration options, and extra w32 code
1196 directory.
1197 * Makefile.am: Add MinGW configuration options, and extra w32 code
1198 directory.
1199 * main.c: Determine correct program string (after last \ without .exe).
1200 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1201 type fix x2
1202 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1203 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1204 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1205 environment support.
1207 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1209 * function.c (func_shell): When initializing error_prefix, check
1210 that reading file name is not null. This fixes long-standing
1211 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1213 2005-02-09 Paul D. Smith <psmith@gnu.org>
1215 * maintMakefile: Update the CVS download URL to simplify them.
1216 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1217 downloading the .texi files from Savannah now.
1219 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1221 * main.c (handle_non_switch_argument): Only add variables to
1222 command_variables if they're not already there: duplicate settings
1223 waste space and can be confusing to read.
1225 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1226 this header is never included by non-WINDOWS32 code, and it
1227 requires <config.h> to define which isn't always included first.
1229 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1230 testing MINGW32 versions.
1232 * main.c (log_working_directory): flush stdout to be sure the WD
1233 change is printed before any stderr messages show up.
1235 2005-02-01 Paul D. Smith <psmith@gnu.org>
1237 * maintMakefile (po_repo): Update the GNU translation site URL.
1239 2004-12-01 Paul D. Smith <psmith@gnu.org>
1241 * main.c (main): Change char* env_shell to struct variable shell_var.
1242 * variable.c (target_environment): Use new shell_var.
1244 2004-11-30 Paul D. Smith <psmith@gnu.org>
1246 * configure.in: The old way we avoided creating build.sh from
1247 build.sh.in before build.sh.in exists doesn't work anymore; we
1248 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1249 the help!). This also keeps automake from complaining.
1250 * Makefile.am (README): Add a dummy target so automake won't
1251 complain that this file doesn't exist when we checkout from CVS.
1252 * maintMakefile (.dep_segment): Rewrite this rule since newer
1253 versions of automake don't provide DEP_FILES.
1255 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1257 Implementation of `realpath' and `abspath' built-in functions.
1259 * configure.in: Check for realpath.
1260 * function.c (abspath): Return an absolute file name that does
1261 not contain any `.' or `..' components, nor repeated `/'.
1262 * function.c (func_abspath): For each name call abspath.
1263 * function.c (func_realpath): For each name call realpath
1264 from libc or delegate to abspath if realpath is not available.
1265 * doc/make.texi (Functions for File Names): Document new functions.
1266 * doc/make.texi (Quick Reference): Ditto.
1268 2004-11-28 Paul D. Smith <psmith@gnu.org>
1270 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1271 arguments. Fixes bug #10252.
1273 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1275 * main.c (main): Set SHELL to v_noexport by default. Remember the
1276 original environment setting of SHELL in the env_shell variable.
1277 * main.h: Export new env_shell variable.
1278 * variable.c (target_environment): If we find a v_noexport
1279 variable for SHELL, add a SHELL variable with the env_shell value.
1280 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1281 * doc/make.texi (Variables/Recursion): Ditto.
1283 2004-11-28 Paul D. Smith <psmith@gnu.org>
1285 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1286 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1287 Patch by Alessandro Vesely.
1289 2004-11-12 Paul D. Smith <psmith@gnu.org>
1291 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1292 the command line if it's inside a string.
1293 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1295 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1297 * function.c (func_lastword): New function: return last word
1298 from the list of words.
1299 * doc/make.texi: Document $(lastword ). Fix broken links in
1300 Quick Reference section.
1302 2004-10-06 Paul D. Smith <psmith@gnu.org>
1304 Apply patch from Alessandro Vesely, provided with bug # 9748.
1305 Fix use of tmpnam() to work with Borland C.
1307 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1308 construction of a temporary filename, and call new function
1309 create_batch_filename().
1310 (create_batch_filename) [WINDOWS32]: New function to create a
1311 temporary filename.
1313 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1315 * read.c (record_target_var): Expand simple pattern-specific
1316 variable.
1317 * variable.c (initialize_file_variables): Do not expand simple
1318 pattern-specific variable.
1320 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1322 * remake.c (update_file_1): When rebuilding makefiles inherit
1323 dontcare flag from a target that triggered update.
1325 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1327 * variable.c (initialize_file_variables): Mark pattern-specific
1328 variable as a per-target and copy export status.
1330 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1332 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1334 * implicit.c (pattern_search): When considering an implicit rule's
1335 prerequisite check that it is actually a target rather then
1336 just an entry in the file hashtable.
1338 2004-09-21 Paul D. Smith <psmith@gnu.org>
1340 * read.c (readstring): Fix some logic errors in backslash handling.
1341 (eval): Remove some unnecessary processing in buffer handling.
1342 (record_target_var): Assert that parse_variable_definition() succeeded.
1343 Reported by: Markus Mauhart <qwe123@chello.at>.
1345 * misc.c: Removed the sindex() function. All instances of this
1346 function were trivially replaceable by the standard strstr()
1347 function, and that function will always have better (or certainly
1348 no worse) performance than the very simple-minded algorithm
1349 sindex() used. This can matter with complex makefiles.
1350 * make.h: Remove the prototype for sindex().
1351 * function.c (subst_expand): Convert sindex() call to strstr().
1352 This means we no longer need to track the TLEN value so remove that.
1353 (func_findstring): Convert sindex() to strstr().
1354 * commands.c (chop_commands): Convert sindex() calls to strstr().
1355 Suggested by: Markus Mauhart <qwe123@chello.at>.
1357 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1358 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1359 If SHELL is set to CMD.EXE then assume it's batch-mode and
1360 non-unixy. I wrote the code differently from the patch, though,
1361 to make it safer. This also resolves bug #9174.
1363 2004-09-20 Paul D. Smith <psmith@gnu.org>
1365 * expand.c (variable_expand_string): Modify to invoke
1366 patsubst_expand() instead of subst_expand(); the latter didn't
1367 handle suffix patterns correctly.
1368 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1369 was used only from variable_expand_string() and is no longer used
1370 there.
1371 (func_subst): Ditto, on call to subst_expand().
1372 (patsubst_expand): Require the percent pointers to point to the
1373 character after the %, not to the % itself.
1374 * read.c (record_files): New call criteria for patsubst_expand().
1375 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1376 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1378 2004-09-19 Paul D. Smith <psmith@gnu.org>
1380 * function.c (subst_expand): Fix a check in by_word: look for a
1381 previous blank if we're beyond the beginning of the string, not
1382 the beginning of the word.
1383 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1385 2004-05-16 Paul D. Smith <psmith@gnu.org>
1387 * remake.c (update_goal_chain): Change the argument specifying
1388 whether we're rebuilding makefiles to be a global variable,
1389 REBUILDING_MAKEFILES.
1390 (complain): Extract the code that complains about no rules to make
1391 a target into a separate function.
1392 (update_file_1): If we tried to rebuild a file during the makefile
1393 rebuild phase and it was dontcare, then no message was printed.
1394 If we then try to build the same file during the normal build,
1395 print a message this time.
1396 (remake_file): Don't complain about un-remake-able files when
1397 we're rebuilding makefiles.
1399 2004-05-11 Paul D. Smith <psmith@gnu.org>
1401 * job.c (construct_command_argv_internal): OS/2 patches from
1402 Andreas Buening <andreas.buening@nexgo.de>.
1404 2004-05-10 Paul D. Smith <psmith@gnu.org>
1406 * remake.c (update_file): Don't walk the double-colon chain unless
1407 this is a double-colon rule. Fix suggested by Boris Kolpackov
1408 <boris@kolpackov.net>.
1410 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1411 * readme.vms: New section describing OpenVMS support and issues.
1412 * default.c (default_variables): Add support for IA64.
1413 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1414 without some privilege aborts make with the error
1415 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1416 pressing Ctrl+Y and the input device is no terminal. The change
1417 catches this error and just continues.
1419 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1421 2004-04-25 Paul D. Smith <psmith@gnu.org>
1423 * commands.c (set_file_variables): Set $< properly in the face of
1424 order-only prerequisites.
1425 Patch from Boris Kolpackov <boris@kolpackov.net>
1427 2004-04-21 Bob Byrnes <byrnes@curl.com>
1429 * main.c (main): Notice failures to remake makefiles.
1431 2004-03-28 Paul D. Smith <psmith@gnu.org>
1433 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1435 * job.c: No default shell for RISC OS.
1436 (load_too_high): Hard-code the return to 1.
1437 (construct_command_argv_internal): No sh_chars or sh_cmds.
1438 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1440 2004-03-20 Paul D. Smith <psmith@gnu.org>
1442 * variable.c (do_variable_definition): Don't append from the
1443 global set if a previous non-appending target-specific variable
1444 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1445 (with fix).
1447 * expand.c (reference_variable): Don't give up on variables with
1448 no value that have the target-specific append flag set: they might
1449 have a value after all. Reported by Oliver Schmidt
1450 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1451 <nikulin@dx1cmd.inp.nsk.su>.
1453 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1454 refer to absolute pathnames in directories that don't exist: some
1455 portion of the makefile could create those directories before we
1456 match the pattern. Fixes bugs #775 and #108.
1458 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1460 * main.c (main): Free makefile_mtimes if we have any.
1461 * README.W32.template: Update documentation for the current status
1462 of the MS-Windows port.
1463 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1464 environment variable is sometimes already defined which causes the
1465 build to fail.
1466 * main.c (debug_signal_handler): Only define this function if
1467 SIGUSR1 is available.
1469 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1471 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1472 * README.OS2.template: Documentation updates.
1473 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1474 link line for safety.
1475 * maintMakefile (build.sh.in): Remove an extraneous ")".
1476 * job.c (child_execute_job): Close saved FDs.
1477 * job.c (exec_command) [OS/2]: exec_command(): If the command
1478 can't be exec'ed and if the shell is not Unix-sh, then try again
1479 with argv = { "cmd", "/c", ... }. Normally, this code is never
1480 reached for the cmd shell unless the command really doesn't exist.
1481 (construct_command_argv_internal) [OS/2]: The code for cmd
1482 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1483 The CMD builtin commands are case insensitive so use strcasecmp().
1485 2004-03-19 Paul D. Smith <psmith@gnu.org>
1487 * read.c (do_define): Re-order line counter increment so the count
1488 is accurate (we were losing one line per define). Reported by
1489 Dave Yost <Dave@Yost.com>.
1491 2004-03-06 Paul D. Smith <psmith@gnu.org>
1493 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1494 compiler.
1495 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1496 * misc.c (message,error,fatal): Ditto.
1497 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1498 * config.h.W32.template: Ditto.
1499 * config.h-vms.template: Ditto.
1500 * config.ami.template: Ditto.
1502 2004-03-04 Paul D. Smith <psmith@gnu.org>
1504 * README.template: Add a note about broken /bin/sh on SunOS
1505 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1507 * misc.c (message, error, fatal): Don't use "..." if we're using
1508 varargs. ansi2knr should handle this but it doesn't work: it
1509 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1510 done. On many systems (SunOS for example) va_dcl is a #define.
1511 So, force the use of the non-"..." version on pre-ANSI compilers.
1513 * maintMakefile (sign-dist): Create some rules to help automate
1514 the new GNU ftp upload method.
1516 2004-02-24 Paul D. Smith <psmith@gnu.org>
1518 * config.h.W32.template: Add HAVE_STDARG_H
1519 * config.h-vms.template: Ditto.
1520 * config.ami.template: Ditto.
1522 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1524 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1525 * build_w32.bat: Remove extra "+".
1527 2004-02-23 Paul D. Smith <psmith@gnu.org>
1529 * make.h: Create an UNUSED macro to mark unused parameters.
1530 * (many): Clean up warnings by applying UNUSED, fixing
1531 signed/unsigned incompatibilities, etc.
1533 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1534 autoconf warnings.
1535 * filedef.h: Name the command_state enumeration.
1536 * file.c (set_command_state): Use the enumeration in the function
1537 argument.
1539 * configure.in: Explicitly set SET_MAKE to empty, to disable
1540 MAKE=make even when no make already exists. Fix bug #3823.
1542 2004-02-22 Paul D. Smith <psmith@gnu.org>
1544 * maintMakefile: Perl script to clean up all non-CVS files. Use
1545 it on all the subdirectories for the cvs-clean target.
1547 * main.c (decode_switches): Require non-empty strings for all our
1548 string command-line options. Fixes Debian bug # 164165.
1550 * configure.in: Check for stdarg.h and varargs.h.
1551 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1552 for printing messages.
1553 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1554 (message): Ditto.
1555 (error): Ditto.
1556 (fatal): Ditto.
1558 A number of patches for OS/2 support from Andreas Buening
1559 <andreas.buening@nexgo.de>:
1561 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1562 disable the SIGCHLD handler.
1563 (reap_children) [OS/2]: Remove special handling of job_rfd.
1564 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1565 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1566 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1567 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1568 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1569 systems.
1571 2004-02-21 Paul D. Smith <psmith@gnu.org>
1573 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1574 <mail@kristov.de> reports that if process_begin() fails we don't
1575 handle the error condition correctly in all cases.
1576 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1577 to have a newline on the message.
1579 * job.c (construct_command_argv_internal): Add "test" to UNIX
1580 sh_cmds[]. Fixes Savannah bug # 7606.
1582 2004-02-04 Paul D. Smith <psmith@gnu.org>
1584 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1585 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1586 Hartmut Becker <Hartmut.Becker@hp.com>.
1588 2004-01-21 Paul D. Smith <psmith@gnu.org>
1590 * job.c (load_too_high): Implement an algorithm to control the
1591 "thundering herd" problem when using -l to control job creation
1592 via the load average. The system only recomputes the load once a
1593 second but we can start many jobs in a second. To solve this we
1594 keep track of the number of jobs started in the last second and
1595 apply a weight to try to guess what a correct load would be.
1596 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1597 Also fixes bug #4693.
1598 (reap_children): Decrease the job count for this second.
1599 (start_job_command): Increase the job count for this second.
1601 * read.c (conditional_line): Expand the text after ifn?def before
1602 checking to see if it's a single word. Fixes bug #7257.
1604 2004-01-09 Paul D. Smith <psmith@gnu.org>
1606 * file.c (print_file): Recurse to print all targets in
1607 double-colon rules. Fixes bug #4518, reported (with patch) by
1608 Andrew Chatham <chatham@google.com>.
1610 2004-01-07 Paul D. Smith <psmith@gnu.org>
1612 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1613 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1614 AC_FUNC_SETVBUF_REVERSED.
1616 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1617 (MAKE Variable): Fix Savannah bug #4898.
1619 * job.c (construct_command_argv_internal): Add "!" to the list of
1620 shell escape chars. POSIX sh allows it to appear before a
1621 command, to negate the exit code. Fixes bug #6404.
1623 * implicit.c (pattern_search): When matching an implicit rule,
1624 remember which dependencies have the ignore_mtime flag set.
1625 Original fix provided in Savannah patch #2349, by Benoit
1626 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1628 2003-11-22 Paul D. Smith <psmith@gnu.org>
1630 * README.W32.template (Outputs): Clarification on -j with
1631 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1632 <jg-make@jguk.org>.
1634 2003-11-02 Paul D. Smith <psmith@gnu.org>
1636 * function.c (func_if): Strip all the trailing whitespace from the
1637 condition, then don't expand it. Fixed bug # 5798.
1639 * expand.c (recursively_expand_for_file): If we're expanding a
1640 variable with no file context, then use the variable's context.
1641 Fixes bug # 6195.
1643 2003-10-21 Paul D. Smith <psmith@gnu.org>
1645 * main.c (log_working_directory): Add newlines to printf()s.
1647 * README.cvs: Add a note to ignore warnings during autoreconf.
1649 * maintMakefile (po_repo): Set a new URL for PO file updates.
1650 (get-config/config.guess get-config/config.sub): Get these files
1651 from the Savannah config project instead of ftp.gnu.org.
1653 2003-10-05 Paul Eggert <eggert@twinsun.com>
1655 * main.c (main): Avoid potential subscript error if environ has
1656 short strings.
1658 2003-08-22 Paul D. Smith <psmith@gnu.org>
1660 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1661 systems which don't yet implement the C89 standard :-/.
1663 2003-07-18 Paul D. Smith <psmith@gnu.org>
1665 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1666 [WINDOWS32]: Initialize hash.
1668 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1670 * dir.c (read_dirstream): Provide a workaround for broken versions of
1671 the MinGW dirent structure.
1673 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1675 * w32/include/dirent.h: Add __MINGW32__ filter.
1677 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1679 * make.h: Add global declaration of *make_host.
1680 * main.c (print_usage): Remove local declaration of *make_host.
1681 (print_version): Display "This program built for ..." after Copyright
1682 notice.
1684 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1686 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1687 execution of "makeinfo --html make.texi".
1689 2003-04-30 Paul D. Smith <psmith@gnu.org>
1691 * build.template: Make some changes to maybe allow this script to
1692 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1694 * README.OS2.template: New file for OS/2 support. Original
1695 contributed by Andreas Buening.
1696 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1697 DOS-style paths.
1699 2003-04-19 Paul D. Smith <psmith@gnu.org>
1701 Fix bug #1405: allow a target to match multiple pattern-specific
1702 variables.
1704 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1705 variable.c, where they've always belonged.
1706 * rule.h: Move the prototypes and struct pattern_var as well.
1707 * variable.c (initialize_file_variables): Invoke
1708 lookup_pattern_var() in a loop, until no more matches are found.
1709 If a match is found, create a new variable set for the target's
1710 pattern variables. Then merge the contents of each matching
1711 pattern variable set into the target's pattern variable set.
1712 (lookup_pattern_var): Change this function to be usable
1713 in a loop. It takes a starting position: if NULL, start at the
1714 beginning; if non-NULL, start with the pattern variable after that
1715 position, and return the next matching pattern.
1716 (create_pattern_var): Create a unique instance of
1717 pattern-specific variables for every definition in the makefile.
1718 Don't combine the same pattern together. This allows us to
1719 process the variable handling properly even when the same pattern
1720 is used multiple times.
1721 (parse_variable_definition): New function: break out the parsing
1722 of a variable definition line from try_variable_definition.
1723 (try_variable_definition): Call parse_variable_definition to
1724 parse.
1725 (print_variable_data_base): Print out pattern-specific variables.
1726 * variable.h (struct variable): Remember when a variable is
1727 conditional. Also remember its flavor.
1728 (struct pattern_var): Instead of keeping a variable set, we just
1729 keep a single variable for each pattern.
1730 * read.c (record_target_var): Each pattern variable contains only a
1731 single variable, not a set, so create it properly.
1732 * doc/make.texi (Pattern-specific): Document the new behavior.
1734 2003-04-17 Paul D. Smith <psmith@gnu.org>
1736 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1737 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1738 file/directory naming rules for VMS so I can't tell whether this
1739 is correct or not.
1741 2003-04-09 Paul D. Smith <psmith@gnu.org>
1743 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1744 DOS-style pathnames: backslash separators and drive specifiers.
1746 2003-03-28 Paul D. Smith <psmith@gnu.org>
1748 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1749 the intermediate flag on all targets. Fixes bug #2515.
1751 2003-03-24 Paul D. Smith <psmith@gnu.org>
1753 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1754 Upgrade to autoconf 2.57 and automake 1.7.3.
1756 * job.c: More OS/2 changes from Andreas Buening.
1758 * file.c (print_file): Fix variable initialization.
1759 Fixes bug #2892.
1761 * remake.c (notice_finished_file):
1763 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1764 some calls (like readdir()) return NULL in valid situations
1765 without resetting errno. Fixes bug #2846.
1767 2003-02-25 Paul D. Smith <psmith@gnu.org>
1769 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1771 * job.c (_is_unixy_shell) [OS/2]: New function.
1772 Set default shell to /bin/sh.
1773 (reap_children): Close the job_rfd pipe here since we don't use a
1774 SIGCHLD handler.
1775 (set_child_handler_action_flags): define this to empty on OS/2.
1776 (start_job_command): Close the jobserver pipe and use
1777 child_execute_job() instead of fork/exec.
1778 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1779 rather than exec'ing, then reconfigure stdin/stdout.
1780 (exec_command): Rewrite to use spawn instead of exec. Return the
1781 PID of the child.
1783 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1784 in DOS. Handle the TEMP environment variable as in DOS. Don't
1785 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1786 use -j in DOS mode. Use child_execute_job() instead of
1787 exec_command().
1789 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1790 spawn() instead.
1792 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1793 prototypes that return values.
1795 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1797 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1798 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1799 for OS/2.
1800 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1801 DOS paths.
1803 2003-02-24 Paul D. Smith <psmith@gnu.org>
1805 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1806 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1807 (child_execute_job) [VMS]: Handle error status properly.
1808 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1810 * function.c (func_shell): Use EINTRLOOP() while reading from the
1811 subshell pipe (Fixes bug #2502).
1812 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1813 jobserver pipe.
1814 * main.c (main): Ditto.
1816 2003-01-30 Paul D. Smith <psmith@gnu.org>
1818 * read.c (eval): eval() was not fully reentrant, because the
1819 collapsed buffer was static. Change it to be an automatic
1820 variable so that eval() can be invoked recursively.
1821 Fixes bug # 2238.
1822 (eval): Apply patch # 1022: fix memory reference error on long
1823 target-specific variable lines.
1824 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1826 * function.c (check_numeric): Combine the is_numeric() function
1827 into this function, since it's only called from one place.
1828 Constify this function. Have it print the incorrect string in the
1829 error message. Fixes bug #2407.
1830 (strip_whitespace): Constify.
1831 (func_if): Constify.
1832 * expand.c (expand_argument): Constify.
1834 2003-01-29 Paul D. Smith <psmith@gnu.org>
1836 Fix bug # 2169, also reported by other people on various systems.
1838 * make.h: Some systems, such as Solaris and PTX, do not fully
1839 implement POSIX-compliant SA_RESTART functionality; important
1840 system calls like stat() and readdir() can still fail with EINTR
1841 even if SA_RESTART has been set on the signal handler. So,
1842 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1843 EINTR for system calls which return -1 or 0 (NULL), respectively,
1844 on error.
1845 Also, remove the old atomic_stat()/atomic_readdir() and
1846 HAVE_BROKEN_RESTART handling.
1848 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1850 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1851 * remake.c (touch_file): Ditto.
1853 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1854 * read.c (construct_include_path): Ditto.
1855 * remake.c (name_mtime): Ditto.
1856 * vpath.c (selective_vpath_search): Ditto.
1857 * dir.c (find_directory): Ditto.
1858 (local_stat): Ditto.
1859 (find_directory): Use ENULLLOOP() to wrap opendir().
1860 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1862 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1863 atomic_readdir() handling.
1865 2003-01-22 Paul D. Smith <psmith@gnu.org>
1867 * function.c (func_call): Fix Bug #1744. If we're inside a
1868 recursive invocation of $(call ...), mask any of the outer
1869 invocation's arguments that aren't used by this one, so that this
1870 invocation doesn't "inherit" them accidentally.
1872 2002-12-05 Paul D. Smith <psmith@gnu.org>
1874 * function.c (subst_expand): Valery Khamenia reported a
1875 pathological performance hit when doing substitutions on very
1876 large values with lots of words: turns out we were invoking
1877 strlen() a ridiculous number of times. Instead of having each
1878 call to sindex() call strlen() again, keep track of how much of
1879 the text we've seen and pass the length to sindex().
1881 2002-11-19 Paul D. Smith <psmith@gnu.org>
1883 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1886 2002-11-16 Paul D. Smith <psmith@gnu.org>
1888 * NMakefile.template (OBJS): Add hash.c object file.
1889 * SMakefile.template (srcs): Ditto.
1890 * Makefile.ami (objs): Ditto.
1891 * build_w32.bat: Ditto.
1893 * Makefile.DOS.template: Remove extra dependencies.
1895 2002-10-25 Paul D. Smith <psmith@gnu.org>
1897 * expand.c (install_variable_buffer): New function. Install a new
1898 variable_buffer context and return the previous one.
1899 (restore_variable_buffer): New function. Free the current
1900 variable_buffer context and put a previously saved one back.
1901 * variable.h: Prototypes for {install,restore}_variable_buffer.
1902 * function.c (func_eval): Push a new variable_buffer context
1903 before we eval, then restore the old one when we're done.
1904 Fixes Bug #1517.
1906 * read.c (install_conditionals): New function. Install a new
1907 conditional context and return the previous one.
1908 (restore_conditionals): New function. Free the current
1909 conditional context and put a previously saved one back.
1910 (eval): Use the {install,restore}_conditionals for "include"
1911 handling.
1912 (eval_buffer): Use {install,restore}_conditionals to preserve the
1913 present conditional state before we evaluate the buffer.
1914 Fixes Bug #1516.
1916 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1917 and $(value ...).
1918 (Recursion): Add a variable index entry for CURDIR.
1920 * README.cvs: Update to appropriate versions.
1921 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1922 don't need to copy loadavg.c: automake is smart enough to create
1923 it for me. Still have a bug in automake related to ansi2knr tho.
1925 2002-10-14 Paul D. Smith <psmith@gnu.org>
1927 * remake.c (notice_finished_file): Only touch targets if they have
1928 at least one command (as per POSIX). Resolve Bug #1418.
1930 * *.c: Convert to using ANSI C-style function definitions.
1931 * Makefile.am: Enable the ansi2knr feature of automake.
1932 * configure.in: ditto.
1934 2002-10-13 Paul D. Smith <psmith@gnu.org>
1936 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1937 for automatic variable values like $^, etc. In the case of very
1938 large lists of prerequisites this causes problems. Instead reuse
1939 a static buffer (resizeable) for each variable.
1941 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1942 target-specific variable definitions. Check for it and set an
1943 "exported" flag.
1944 (record_target_var): Set the export field to v_export if the
1945 "exported" flag is set.
1946 * doc/make.texi (Target-specific): Document the ability to use
1947 "export".
1949 * doc/make.texi: Change the name of the section on automatic
1950 variables from "Automatic" to "Automatic Variables". Added text
1951 clarifying the scope of automatic variables.
1953 2002-10-04 Paul D. Smith <psmith@gnu.org>
1955 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1956 as () braces.
1957 (record_files): Ditto.
1959 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1960 the search for the '=' to only within the enclosing parens.
1962 2002-10-03 Paul D. Smith <psmith@gnu.org>
1964 Version 3.80 released.
1966 * dir.c: Change hash functions to use K&R function definition style.
1967 * function.c: Ditto.
1968 * read.c: Ditto.
1969 * variable.c: Ditto.
1971 Update to automake 1.7.
1973 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1974 (pdf): Remove this target as automake now provides one.
1976 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1978 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1980 * makefile.com: Updates for GNU make 3.80.
1981 * makefile.vms: Ditto.
1983 2002-09-23 Paul D. Smith <psmith@gnu.org>
1985 * read.c (enum make_word_type): Remove w_comment.
1986 (get_next_mword): Don't treat comment characters as special; where
1987 this function is used we will never see a comment (it's stripped
1988 before we get here) and treating comments specially means that
1989 targets like "foo\#bar" aren't handled properly.
1991 2002-09-18 Paul D. Smith <psmith@gnu.org>
1993 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1995 * read.c (eval): Expansion of arguments to export/unexport was
1996 ignoring all arguments after the first one. Change the algorithm
1997 to expand the whole line once, then parse the results.
1999 2002-09-17 Paul D. Smith <psmith@gnu.org>
2001 Fix Bug #940 (plus another bug I found while looking at this):
2003 * read.c (record_target_var): enter_file() will add a new entry if
2004 it's a double-colon target: we don't want to do that in this
2005 situation. Invoke lookup_file() and only enter_file() if it does
2006 not already exist. If the file we get back is a double-colon then
2007 add this variable to the "root" double-colon target.
2009 * variable.c (initialize_file_variables): If this file is a
2010 double-colon target but is not the "root" target, then initialize
2011 the root and make the root's variable list the parent of our
2012 variable list.
2014 2002-09-13 Paul D. Smith <psmith@gnu.org>
2016 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2018 * hash.c (round_up_2): Get rid of a warning.
2020 2002-09-12 Paul D. Smith <psmith@gnu.org>
2022 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2023 so it doesn't complain about getloadavg.c.
2025 * commands.c (set_file_variables): Make sure we always alloca() at
2026 least 1 character for the value of $? (for '\0').
2028 2002-09-11 Paul D. Smith <psmith@gnu.org>
2030 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2031 macro to use RESULT instead of the incorrect _RESULT_.
2033 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2034 and atomic_readdir(). We need to #include dirent.h to get this to
2035 work.
2036 * misc.c (atomic_readdir): Fix typos.
2038 2002-09-10 Paul D. Smith <psmith@gnu.org>
2040 * read.c (eval): Expand variable lists given to export and
2041 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2042 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2044 * doc/make.texi (Variables/Recursion): Document this.
2045 (Conditional Syntax): And here.
2047 2002-09-09 Paul D. Smith <psmith@gnu.org>
2049 * configure.in: Check for memmove().
2051 2002-09-07 Paul D. Smith <psmith@gnu.org>
2053 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2054 Michael Sterrett <msterret@coat.com> reports that while it has
2055 SA_RESTART, it does not work properly.
2057 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2058 that invokes stat() and loops to do it again if it returns EINTR.
2059 (atomic_readdir): Ditto, with readdir().
2061 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2062 and readdir() to atomic_stat() and atomic_readdir().
2064 2002-09-04 Paul D. Smith <psmith@gnu.org>
2066 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2067 reports that GNU make sometimes doesn't recognize that targets can
2068 be made, when directories can be created as prerequisites. He
2069 reports that changing the order of predicates in the DEP->changed
2070 flag test so that lookup_file() is always performed, solves this
2071 problem.
2073 2002-08-08 Paul D. Smith <psmith@gnu.org>
2075 * configure.in: Require a newer version of gettext.
2077 * misc.c (perror_with_name): Translate the format string (for
2078 right-to-left language support).
2079 (pfatal_with_name): Ditto.
2081 * main.c: Create a static array of strings to store the usage
2082 text. This is done to facilitate translations.
2083 (struct command_switch): Remove argdesc and description fields.
2084 (switches): Remove values for obsolete fields.
2085 (print_usage): Print each element of the usage array.
2087 * hash.c: Change function definitions to be K&R style.
2089 2002-08-02 Paul D. Smith <psmith@gnu.org>
2091 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2092 this one because it's too hard to get right. We'll look at it for
2093 a future release.
2094 * main.c (main): Don't create the .TARGETS variable.
2095 * variable.c (handle_special_var): Don't handle .TARGETS.
2097 2002-08-01 Paul D. Smith <psmith@gnu.org>
2099 * main.c (switches): Add a new option, -B (--always-make). If
2100 specified, make will rebuild all targets that it encounters even
2101 if they don't appear to be out of date.
2102 (always_make_flag): New flag.
2103 * make.h: Extern always_make_flag.
2104 * remake.c (update_file_1): Check always_make_flag; if it's set we
2105 will always rebuild any target we can, even if none of its
2106 prerequisites are newer.
2107 * NEWS: Mention it.
2109 * doc/make.texi (Shell Function): Make it clear that make
2110 variables marked as "export" are not passed to instances of the
2111 shell function.
2113 Add new introspection variable .VARIABLES and .TARGETS.
2115 * variable.c (handle_special_var): New function. If the variable
2116 reference passed in is "special" (.VARIABLES or .TARGETS),
2117 calculate the new value if necessary. .VARIABLES is handled here:
2118 walk through the hash of defined variables and construct a value
2119 which is a list of the names. .TARGETS is handled by
2120 build_target_list().
2121 (lookup_variable): Invoke handle_special_var().
2122 * file.c (build_target_list): Walk through the hask of known files
2123 and construct a list of the names of all the ones marked as
2124 targets.
2125 * main.c (main): Initialize them to empty (and as simple variables).
2126 * doc/make.texi (Special Variables): Document them.
2127 * NEWS: Mention them.
2129 * variable.h (struct variable): Add a new flag "exportable" which
2130 is true if the variable name is valid for export.
2131 * variable.c (define_variable_in_set): Set "exportable" when a new
2132 variable is defined.
2133 (target_environment): Use the "exportable" flag instead of
2134 re-checking the name here... an efficiency improvement.
2136 2002-07-31 Paul D. Smith <psmith@gnu.org>
2138 * config.h-vms.template: Updates to build on VMS. Thanks to
2139 Brian_Benning@aksteel.com for helping verify the build.
2140 * makefile.com: Build the new hash.c file.
2141 * hash.h: Use strcpmi(), not stricmp(), in the
2142 HAVE_CASE_INSENSITIVE_FS case.
2144 2002-07-30 Paul D. Smith <psmith@gnu.org>
2146 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2147 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2148 Reported by <Brian_Benning@aksteel.com>.
2150 2002-07-10 Paul D. Smith <psmith@gnu.org>
2152 * variable.c (pop_variable_scope): Remove variable made unused by
2153 new hash infrastructure.
2154 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2155 comparisons as well as name comparisons.
2156 * variable.h: Add a prototype for new hash_init_function_table().
2157 * file.c (lookup_file): Remove variables made unused by new hash
2158 infrastructure.
2159 * dir.c (directory_contents_hash_2): Missing return of hash value.
2160 (dir_contents_file_exists_p): Remove variables made unused by new
2161 hash infrastructure.
2164 Installed Greg McGary's integration of the hash functions from the
2165 GNU id-utils package:
2167 2002-07-10 Greg McGary <greg@mcgary.org>
2169 * scripts/functions/filter-out: Add literals to to the
2170 pattern space in order to add complexity, and trigger
2171 use of an internal hash table. Fix documentation strings.
2172 * scripts/targets/INTERMEDIATE: Reverse order of files
2173 passed to expected `rm' command.
2175 2002-07-10 Greg McGary <greg@mcgary.org>
2177 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
2178 * hash.c: New file, taken from id-utils.
2179 * hash.h: New file, taken from id-utils.

2188 (file_hash_enter): Remove function decl.
2189 (init_hash_files): New function decl.
2191 * ar.c (ar_name): Delay call to strlen until needed.
2192 * main.c (initialize_global_hash_tables): New function.
2193 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
2194 * misc.c (remove_comments): Pass char constants to find_char_unquote.
2195 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
2197 * dir.c (hash.h): New #include.
2198 (struct directory_contents) [next, files]: Remove members.
2199 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

2209 (find_directory): Use new hash table package.
2210 (dir_contents_file_exists_p): Likewise.
2211 (file_impossible): Likewise.
2212 (file_impossible_p): Likewise.
2213 (print_dir_data_base): Likewise.
2214 (open_dirstream): Likewise.
2215 (read_dirstream): Likewise.
2216 (hash_init_directories): New function.
2218 * file.c (hash.h): New #include.
2219 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
2220 (files): Change type to `struct hash_table'.
2221 (lookup_file): Use new hash table package.
2222 (enter_file): Likewise.
2223 (remove_intermediates): Likewise.
2224 (snap_deps): Likewise.
2225 (print_file_data_base): Likewise.
2227 * function.c
2228 (function_table_entry_hash_1, function_table_entry_hash_2,
2229 function_table_entry_hash_cmp): New functions.
2230 (lookup_function): Remove `table' argument.
2231 Use new hash table package.
2232 (struct a_word) [chain, length]: New members.
2233 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
2234 (struct a_pattern): New struct.
2235 (func_filter_filterout): Pass through patterns noting boundaries
2236 and '%', if present. Note a_word length. Use a hash table if
2237 arglists are large enough to justify cost.
2238 (function_table_init): Renamed from function_table.
2239 (function_table): Declare as `struct hash_table'.
2240 (FUNCTION_TABLE_ENTRIES): New constant.
2241 (hash_init_function_table): New function.
2243 * read.c (hash.h): New #include.
2244 (read_makefile): Pass char constants to find_char_unquote.
2245 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
2246 (uniquize_deps): Use hash table to efficiently identify duplicates.
2247 (find_char_unquote): Accept two char-constant stop chars, rather
2248 than a string constant, avoiding zillions of calls to strchr.
2249 Tighten inner search loops to test only for desired delimiters.
2251 * variable.c (variable_hash_1, variable_hash_2,
2252 variable_hash_cmp): New functions.
2253 (variable_table): Declare as `struct hash_table'.
2254 (global_variable_set): Remove initialization.

2258 (lookup_variable_in_set): Likewise.
2259 (initialize_file_variables): Likewise.
2260 (pop_variable_scope): Likewise.
2261 (create_new_variable_set): Likewise.
2262 (merge_variable_sets): Likewise.
2263 (define_automatic_variables): Likewise.
2264 (target_environment): Likewise.
2265 (print_variable_set): Likewise.
2267 2002-07-10 Paul D. Smith <psmith@gnu.org>
2269 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2270 prerequisite list. A real SysV make will expand the entire
2271 prerequisites list _twice_: we don't do that as it's a big
2272 backward-compatibility problem. We only replace those specific
2273 variables.
2275 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2276 references left in the list of prerequisites. Check for .POSIX as
2277 we record targets, so we can disable non-POSIX behavior while
2278 reading makefiles as well as running them.
2279 (eval): Check the prerequisite list to see if we have anything
2280 that looks like a SysV prerequisite variable reference.
2282 2002-07-09 Paul D. Smith <psmith@gnu.org>
2284 * doc/make.texi (Prerequisite Types): Add a new section describing
2285 order-only prerequisites.
2287 * read.c (uniquize_deps): If we have the same file as both a
2288 normal and order-only prereq, get rid of the order-only prereq,
2289 since the normal one supersedes it.
2291 2002-07-08 Paul D. Smith <psmith@gnu.org>
2293 * AUTHORS: Added Greg McGary to the AUTHORS file.
2294 * NEWS: Blurbed order-only prerequisites.
2295 * file.c (print_file): Show order-only deps properly when printing
2296 the database.
2298 * maintMakefile: Add "update" targets for wget'ing the latest
2299 versions of various external files. Taken from Makefile.maint in
2300 autoconf, etc.
2302 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2303 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2305 2002-07-07 Paul D. Smith <psmith@gnu.org>
2307 * po/*.po: Remove. We'll use wget to retrieve them at release
2308 time.
2310 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2311 rather than a shell you get an exception. Make sure we look up
2312 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2314 * remake.c (notice_finished_file): Fix handling of -t flag.
2315 Patch provided by Henning Makholm <henning@makholm.net>.
2317 * implicit.c (pattern_search): Some systems apparently run short
2318 of stack space, and using alloca() in this function caused an
2319 overrun. I modified it to use xmalloc() on the two variables
2320 which seemed like they might get large. Fixes Bug #476.
2322 * main.c (print_version): Update copyright notice to conform with
2323 GNU standards.
2324 (print_usage): Update help output.
2326 * function.c (func_eval): Create a new make function, $(eval
2327 ...). Expand the arguments, put them into a buffer, then invoke
2328 eval_buffer() on the resulting string.
2329 (func_quote): Create a new function, $(quote VARNAME). Inserts
2330 the value of the variable VARNAME without expanding it any
2331 further.
2333 * read.c (struct ebuffer): Change the linebuffer structure to an
2334 "eval buffer", which can be either a file or a buffer.
2335 (eval_makefile): Move the code in the old read_makefile() which
2336 located a makefile into here: create a struct ebuffer with that
2337 information. Have it invoke the new function eval() with that
2338 ebuffer.
2339 (eval_buffer): Create a new function that creates a struct ebuffer
2340 that holds a string buffer instead of a file. Have it invoke
2341 eval() with that ebuffer.
2342 (eval): New function that contains the guts of the old
2343 read_makefile() function: this function parses makefiles. Obtains
2344 data to parse from the provided ebuffer. Some modifications to
2345 make the flow of the function cleaner and clearer. Still could
2346 use some work here...
2347 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2348 contents of the define/endef variable from the ebuffer.
2349 (readstring): Read the next line from a string-style ebuffer.
2350 (readline): Read the next line from an ebuffer. If it's a string
2351 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2352 from the file.
2354 * dep.h (eval_buffer): Prototype eval_buffer();
2356 * variable.c (do_variable_definition): Make sure that all
2357 non-target-specific variables are registered in the global set.
2358 If we're invoked from an $(eval ...) we might be inside a $(call
2359 ...) or other function which has pushed a variable scope; we still
2360 want to define our variables from evaluated makefile code in the
2361 global scope.
2363 2002-07-03 Greg McGary <greg@mcgary.org>
2365 * dep.h (struct dep) [ignore_mtime]: New member.
2366 [changed]: convert to a bitfield.
2367 * implicit.c (pattern_search): Zero ignore_mtime.
2368 * main.c (main, handle_non_switch_argument): Likewise.
2369 * rule.c (convert_suffix_rule): Likewise.
2370 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2371 (read_makefile): Parse '|' in prerequisite list.
2372 (uniquize_deps): Consider ignore_mtime when comparing deps.
2373 * remake.c (update_file_1, check_dep): Don't force remake for
2374 dependencies that have d->ignore_mtime.
2375 * commands.c (FILE_LIST_SEPARATOR): New constant.
2376 (set_file_variables): Don't include a
2377 prerequisite in $+, $^ or $? if d->ignore_mtime.
2378 Define $|.
2380 2002-06-18 Paul D. Smith <psmith@gnu.org>
2382 * make.texinfo: Updates for next revision. New date/rev/etc.
2383 Recreate all Info menus. Change license on the manual to the GNU
2384 Free Documentation License. A number of typos.
2385 (Variables Simplify): Don't use "-" before it's defined.
2386 (Automatic Prerequisites): Rewrite the target example to work
2387 properly if the compile fails. Remove incorrect comments about
2388 how "set -e" behaves.
2389 (Text Functions): Move the "word", "wordlist", "words", and
2390 "firstword" functions here, from "File Name Functions".
2391 * make-stds.texi: Update from latest GNU version.
2392 * fdl.texi: (created) Import the latest GNU version.
2394 2002-06-06 Paul D. Smith <psmith@gnu.org>
2396 * variable.c (do_variable_definition): New function: extract the
2397 part of try_variable_definition() that actually sets the value
2398 into a separate function.
2399 (try_variable_definition): Call do_variable_definition() after
2400 parsing the variable definition string.
2401 (define_variable_in_set): Make the name argument const.
2403 * variable.h (enum variable_flavor): Make public.
2404 (do_variable_definition): Create prototype.
2406 * read.c (read_all_makefiles): Create a new built-in variable,
2407 MAKEFILE_LIST.
2408 (read_makefile): Add each makefile read in to this variable value.
2410 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2412 * Makefile.DOS.template: Tweak according to changes in the
2413 distribution. Add back the dependencies of *.o files.
2415 * configh.dos.template: Synchronize with config.h.in.
2417 2002-05-09 Paul D. Smith <psmith@gnu.org>
2419 * file.c (file_timestamp_now): Use K&R function declaration.
2421 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2422 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2423 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2424 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2425 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2426 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2427 nlist.n_name is a pointer rather than an array.
2429 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2430 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2431 * configure.in: Use it instead of the old version.
2433 * main.c (main): Prefer setvbuf() to setlinebuf().
2435 2002-05-08 Paul D. Smith <psmith@gnu.org>
2437 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2438 (loadavg_LDADD): Ditto.
2440 2002-04-29 Paul D. Smith <psmith@gnu.org>
2442 * expand.c (recursively_expand_for_file): Rename
2443 recursively_expand() to recursively_expand_for_file() and provide
2444 an extra argument, struct file. If the argument is provided, set
2445 the variable scope to that of the file before expanding.
2446 * variable.h (recursively_expand): Make this a macro that invokes
2447 recursively_expand_for_file() with a NULL file pointer.
2448 * variable.c (target_environment): Call the renamed function and
2449 provide the current file context.
2450 Fixes Debian bug #144306.
2452 2002-04-28 Paul D. Smith <psmith@gnu.org>
2454 Allow $(call ...) user-defined variables to be self-referencing
2455 without throwing an error. Allows implementation of transitive
2456 closures, among other possibly useful things.
2457 Requested by: Philip Guenther <guenther@sendmail.com>
2459 * variable.h (struct variable): Add a new field: exp_count, and
2460 new macros to hold its size and maximum value.
2461 (warn_undefined): Make this a macro.
2462 * variable.c (define_variable_in_set): Initialize it.
2463 * expand.c (recursively_expand): If we detect recursive expansion
2464 of a variable, check the exp_count field. If it's greater than 0
2465 allow the recursion and decrement the count.
2466 (warn_undefined): Remove this (now a macro in variable.h).
2467 * function.c (func_call): Before we expand the user-defined
2468 function, modify its exp_count field to contain the maximum
2469 number of recursive calls we'll allow. After the call, reset it
2470 to 0.
2472 2002-04-21 Paul D. Smith <psmith@gnu.org>
2474 Modified to use latest autoconf (2.53), automake (1.6.1), and
2475 gettext (0.11.1). We're using gettext's new "external" support,
2476 to avoid including libintl source with GNU make.
2478 * README.cvs: New file. Explain how to build GNU make from CVS.
2480 * configure.in: Modify checking for the system glob library.
2481 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2482 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2483 etc. will manage it correctly). Set an automake conditional
2484 USE_LOCAL_GLOB to decide whether to compile the glob library.
2486 * getloadavg.c (main): Include make.h in the "TEST" program to
2487 avoid warnings.
2489 * Makefile.am: Remove special rules for loadavg. Replace them
2490 with Automake capabilities for building extra programs.
2492 * signame.c: This file does nothing if the system provide
2493 strsignal(). If not, it implements strsignal(). If the system
2494 doesn't define sys_siglist, then we make our own; otherwise we use
2495 the system version.
2496 * signame.h: Removed.
2498 * main.c (main): No need to invoke signame_init(). Update copyright.
2500 * ABOUT-NLS: Removed.
2501 * gettext.c: Removed.
2502 * gettext.h: Get a simplified copy from the gettext package.
2503 * po/*: Created.
2504 * i18n/*.po: Moved to po/.
2505 * i18n/: Removed.
2507 * config/*: Created. Contains package configuration helper files.
2508 * config.guess, config.sub: Moved to config directory.
2510 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2511 Rework to use new-style autoconf features. Use the "external"
2512 mode for gettext. Make the build.sh config file conditional on
2513 whether build.sh.in exists, to avoid autoconf errors.
2514 * acinclude.m4: Removed almost all macros as being obsolete.
2515 Rewrote remaining macros to use AC_DEFINE.
2516 * acconfig.h: Removed.
2518 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2519 conditional to handle customs support. Remove special handling
2520 for i18n features.
2522 2002-04-20 Paul D. Smith <psmith@gnu.org>
2524 * function.c (func_call): Don't mark the argument variables $1,
2525 etc. as recursive. They've already been fully expanded so
2526 there's no need to do it again, and doing so strips escaped $'s.
2527 Reported by Sebastian Glita <glseba@yahoo.com>.
2529 * remake.c (notice_finished_file): Walk through double-colon
2530 entries via the prev field, not the next field!
2531 Reported by Greg McGary <greg@mcgary.org>.
2533 * main.c (main): If the user specifies -q and asks for a specific
2534 target which is a makefile, we got an assert. In that case it
2535 turns out we should continue normally instead.
2537 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2539 * i18n/he.po: Installed a new translation.
2541 2002-01-07 Paul D. Smith <psmith@gnu.org>
2543 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2545 2001-12-04 Paul D. Smith <psmith@gnu.org>

2549 2001-09-06 Paul Eggert <eggert@twinsun.com>
2551 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2552 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2554 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2555 are available.
2556 (main): Get rid of any avoidable limit on stack size.
2558 2001-09-04 Paul D. Smith <psmith@gnu.org>
2560 * i18n/da.po: Installed an updated translation.
2562 2001-08-03 Paul D. Smith <psmith@gnu.org>
2564 * i18n/fr.po: Installed an updated translation.
2565 Resolves Debian bug #106720.
2567 2001-06-13 Paul D. Smith <psmith@gnu.org>
2569 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2570 translation.
2572 2001-06-11 Paul D. Smith <psmith@gnu.org>
2574 * i18n/ko.po: Installed a new translation.
2576 2001-05-06 Paul D. Smith <psmith@gnu.org>
2578 Modify the EINTR handling.
2580 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2581 the way in which we manage the file descriptor/signal handler race
2582 trap to be more efficient.
2584 2001-05-06 Paul Eggert <eggert@twinsun.com>
2586 Restart almost all system calls that are interrupted, instead
2587 of worrying about EINTR. The lone exception is the read() for
2588 job tokens.
2590 * configure.in (HAVE_SA_RESTART): New macro.
2591 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2592 * main.c (main): Use SA_RESTART instead of the old,
2593 nonstandard SA_INTERRUPT.
2595 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2596 * main.c (bsd_signal): New function or macro,
2597 if the implementation doesn't supply it.
2598 (The bsd_signal function will be in POSIX 1003.1-200x.)
2599 (HANDLESIG): Remove.
2600 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2602 * make.h (EINTR_SET): Remove.
2603 (SA_RESTART): New macro.
2605 * arscan.c (ar_member_touch): Don't worry about EINTR.
2606 * function.c (func_shell): Likewise.
2607 * job.c (reap_children, free_child, new_job): Likewise.
2608 * main.c (main): Likewise.
2609 * remake.c (touch_file, name_mtime): Likewise.
2611 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2612 if fstat failed with errno!=EINTR, the error was ignored.
2614 * job.c (set_child_handler_action_flags): New function.
2615 (new_job): Use it to temporarily clear the SIGCHLD action flags
2616 while reading the token.
2618 2001-05-02 Paul D. Smith <psmith@gnu.org>
2620 * job.c (start_job_command): Don't add define/endef per-line flags
2621 to the top-level flags setting.
2623 2001-04-03 Paul D. Smith <psmith@gnu.org>
2625 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2626 bit on error, so check for odd return values, not non-0 return
2627 values.
2628 (VMS_get_member_info): Calculate the timezone differences correctly.
2629 Reported by John Fowler <jfowler@nyx.net>.
2632 2001-03-14 Paul D. Smith <psmith@gnu.org>
2634 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2635 value before invoking define_variable().
2636 Reported by John Fowler <jfowler@nyx.net>.
2638 2001-02-07 Paul D. Smith <psmith@gnu.org>
2640 * read.c (record_target_var): If we reset the variable due to a
2641 command-line variable setting overriding it, turn off the "append"
2642 flag.
2644 2001-01-17 Paul D. Smith <psmith@gnu.org>
2646 * variable.c (lookup_variable) [VMS]: When getting values from the
2647 environment, allocate enough space for the _value_ plus escapes,
2648 not enough space for the name plus escapes :-/.
2649 Reported by John Fowler <jfowler@nyx.net>.
2651 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2652 warnings that make generates, so it doesn't look like an error.
2653 Reported by Karl Berry <karl@gnu.org>.
2656 Fix for PR/2020: Rework appended target-specific variables. I'm
2657 fairly confident this algorithm is finally correct.
2659 * expand.c (allocated_variable_append): Rewrite. Instead of
2660 expanding each appended variable then adding all the expanded
2661 strings together, we append all the unexpanded values going up
2662 through the variable set contexts, then expand the final result.
2663 This behaves just like non-target-specific appended variable
2664 values, while the old way didn't in various corner cases.
2665 (variable_append): New function: recursively append the unexpanded
2666 value of a variable, walking from the outermost variable scope to
2667 the innermost.
2668 * variable.c (lookup_variable): Remove the code that looked up the
2669 variable set list if the found variable was "append". We don't
2670 need this anymore.
2671 (lookup_variable_in_set): Make this non-static so we can use it
2672 elsewhere.
2673 (try_variable_definition): Use lookup_variable_in_set() rather
2674 than faking out current_variable_set_list by hand (cleanup).
2675 * variable.h: Add a prototype for the now non-static
2676 lookup_variable_in_set().
2678 2000-11-17 Paul D. Smith <psmith@gnu.org>
2680 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2681 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2682 before throwing a fit.
2684 2000-11-17 Paul D. Smith <psmith@gnu.org>
2686 * read.c (readline): CRLF calculations had a hole, if you hit the
2687 buffer grow scenario just right. Reworked the algorithm to avoid
2688 the need for len or lastlen at all. Problem description with
2689 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2691 2000-10-24 Paul D. Smith <psmith@gnu.org>
2693 * gettext.c (SWAP): Declare this with the prototype, otherwise
2694 some systems don't work (non-32-bit? Reported for Cray T3E).
2695 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2697 2000-10-05 Paul D. Smith <psmith@gnu.org>
2699 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2700 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2702 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2704 2000-09-22 Paul D. Smith <psmith@gnu.org>
2706 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2707 parts of the real gettext.h here, and we expect to really include
2708 the real gettext.h later. If we keep this #define, it's ignored.
2710 2000-09-21 Paul D. Smith <psmith@gnu.org>
2712 * main.c (log_working_directory): Rework the text to use complete
2713 sentences, to make life simpler for the translators.
2715 2000-08-29 Paul D. Smith <psmith@gnu.org>
2717 * file.c (remove_intermediates): Print a debug message before we
2718 remove intermediate files, so the user (if she uses -d) knows
2719 what's going on.
2721 2000-08-21 Paul D. Smith <psmith@gnu.org>
2723 * variable.c (try_variable_definition): Change how we handle
2724 target-specific append variable defns: instead of just setting the
2725 value, expand it as an append _but_ only within the current
2726 target's context. Otherwise we lose all but the last value if the
2727 variable is appended more than once within the current target
2728 context. Fixes PR/1831.
2730 2000-08-16 Paul D. Smith <psmith@gnu.org>
2732 * function.c (func_shell): Nul-terminate the buffer before
2733 printing an exec error message (just in case it's not!).
2734 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2736 2000-07-25 Paul D. Smith <psmith@gnu.org>
2738 * job.c (construct_command_argv_internal): Add "~" to the list of
2739 sh_chars[] which disallow optimizing out the shell call.
2741 2000-07-23 Paul Eggert <eggert@twinsun.com>
2743 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2744 supersedes --disable-nsec-timestamps.
2745 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2746 * README: Remove --disable-nsec-timestamps.
2748 * filedef.h (struct file.low_resolution_time): New member.
2749 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2750 * remake.c (update_file_1):
2751 Avoid spurious rebuilds due to low resolution time stamps,
2752 generalizing the earlier code that applied only to archive members.
2753 (f_mtime): Archive members always have low resolution time stamps.
2755 * configure.in: Remove --disable-nsec-timestamps, as this has
2756 been superseded by .LOW_RESOLUTION_TIME.
2758 2000-07-23 Paul Eggert <eggert@twinsun.com>
2760 * configure.in (enable_nsec_timestamps): Renamed from
2761 make_cv_nsec_timestamps, since enable/disable options
2762 shouldn't be cached.
2764 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2765 and Paul Eggert <eggert@twinsun.com>
2767 * file.c (file_timestamp_now):
2768 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2769 so that clock_gettime is not linked unless needed.
2771 * filedef.h (FILE_TIMESTAMP_HI_RES):
2772 Remove definition; "configure" now does this.
2774 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2775 to before high resolution file timestamp check,
2776 since that check now uses uintmax_t.
2777 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2778 high resolution file timestamps.
2779 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2780 so that we don't link in clock_gettime unnecessarily.
2782 2000-07-17 Paul D. Smith <psmith@gnu.org>
2784 * i18n/ja.po: New version of the translation file.
2786 2000-07-07 Paul D. Smith <psmith@gnu.org>
2788 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2789 the offset calculation.
2790 (name_mtime): Replace EINTR test with EINTR_SET macro.
2792 2000-07-07 Paul Eggert <eggert@twinsun.com>
2794 Fix for PR/1811:
2796 * remake.c (update_file_1):
2797 Avoid spurious rebuilds of archive members due to their
2798 timestamp resolution being only one second.
2799 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2800 the clock's resolution being lower than file timestamps'.
2801 When warning about future timestamps, report only the discrepancy,
2802 not the absolute value of the timestamp and the current time.
2804 * file.c (file_timestamp_now): New arg RESOLUTION.
2805 * filedef.h (file_timestamp_now): Likewise.
2806 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2808 2000-07-05 Paul D. Smith <psmith@gnu.org>
2810 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2811 to listp. Fixes PR/1793.
2813 2000-06-26 Paul Eggert <eggert@twinsun.com>
2815 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2817 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2819 * remake.c (f_mtime): Remove unused var memtime.
2821 2000-06-25 Martin Buchholz <martin@xemacs.org>
2823 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2824 Ran spell-check on make.texinfo.
2826 2000-06-23 Paul D. Smith <psmith@gnu.org>
2828 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2829 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2830 * make.h: Define these macros.
2832 * Version 3.79.1 released.
2834 * configure.in: Add a new option, --disable-nsec-timestamps, to
2835 avoid using sub-second timestamps on systems that support it. It
2836 can lead to problems, e.g. if your makefile relies on "cp -p".
2837 * README.template: Document the issue with "cp -p".
2839 * config.guess, config.sub: Updated.
