3 * commands.c (set_file_variables): Realloc, not malloc, the static
4 string values to avoid memory leaks.
6 * expand.c (recursively_expand_for_file): Only set reading_file to
9 * implicit.c (pattern_search): We need to make a copy of the stem
10 if we get it from an intermediate dep, since those get freed.
12 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
14 (enter_file) [VMS]: Ditto.
15 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
17 2006-02-18 Eli Zaretskii <eliz@gnu.org>
19 * job.c (construct_command_argv_internal): Don't create a temporary
20 script/batch file if we are under -n. Call _setmode to switch the
21 script file stream to text mode.
23 2006-02-17 Paul D. Smith <psmith@gnu.org>
25 * variable.c (merge_variable_set_lists): Don't try to merge the
26 global_setlist. Not only is this useless, but it can lead to
27 circularities in the linked list, if global_setlist->next in one
28 list gets set to point to another list which also ends in
30 Fixes Savannah bug #15757.
32 2006-02-15 Paul D. Smith <psmith@gnu.org>
34 Fix for Savannah bug #106.
36 * expand.c (expanding_var): Keep track of which variable we're
37 expanding. If no variable is being expanded, it's the same as
39 * make.h (expanding_var): Declare it.
40 * expand.c (recursively_expand_for_file): Set expanding_var to the
41 current variable we're expanding, unless there's no file info in
42 it (could happen if it comes from the command line or a default
43 variable). Restore it before we exit.

45 info instead of the reading_file info.
46 * function.c (check_numeric): Ditto.
48 (func_wordlist): Ditto.
50 (expand_builtin_function): Ditto.
51 (handle_function): Ditto.
53 2006-02-14 Paul D. Smith <psmith@gnu.org>
55 * read.c (eval): Even if the included filenames expands to the
56 empty string we still need to free the allocated buffer.
58 * implicit.c (pattern_search): If we allocated a variable set for
59 an impossible file, free it.
60 * variable.c (free_variable_set): New function.
61 * variable.h: Declare it.

64 strcache, so there's never any need to alloc/free them.
67 * main.c (main): Add "archives" to the .FEATURES variable if
68 archive support is enabled.
69 * doc/make.texi (Special Variables): Document it.
71 2006-02-13 Paul D. Smith <psmith@gnu.org>
73 * implicit.c (pattern_search): Add checking for DOS pathnames to
74 the pattern rule target LASTSLASH manipulation.
75 Fixes Savannah bug #11183.

79 * (ALL FILES): Updated copyright and license notices.
81 2006-02-10 Paul D. Smith <psmith@gnu.org>
83 A new internal capability: the string cache is a read-only cache
84 of strings, with a hash table interface for fast lookup. Nothing
85 in the cache will ever be freed, so there's no need for reference
86 counting, etc. This is the beginning of a full solution for
87 Savannah bug #15182, but for now we only store makefile names here.
89 * strcache.c: New file. Implement a read-only string cache.
90 * make.h: Add prototypes for new functions.
91 * main.c (initialize_global_hash_tables): Initialize the string cache.
92 (print_data_base): Print string cache stats.
93 * read.c (eval_makefile): Use the string cache to store makefile
94 names. Rewrite the string allocation to be sure we free everything.
96 2006-02-10 Eli Zaretskii <eliz@gnu.org>
98 * dir.c (dir_contents_file_exists_p): Don't opendir if the
99 directory time stamp didn't change, except on FAT filesystems.
100 Suggested by J. David Bryan <jdbryan@acm.org>.
102 2006-02-09 Paul D. Smith <psmith@gnu.org>
104 * function.c (func_or): Implement a short-circuiting OR function.
105 (func_and): Implement a short-circuiting AND function.
106 (function_table_init): Update the table with the new functions.
107 * doc/make.texi (Conditional Functions): Changed the "if" section
108 to one on general conditional functions. Added documentation for
109 $(and ...) and $(or ...) functions.
110 * NEWS: Note new $(and ...) and $(or ...) functions.

119 2006-02-06 Paul D. Smith <psmith@gnu.org>
121 * vpath.c (selective_vpath_search): If the file we find has a
122 timestamp from -o or -W, use that instead of the real time.
123 * remake.c (f_mtime): If the mtime is a special token from -o or
124 -W, don't overwrite it with the real mtime.
125 Fixes Savannah bug #15341.
127 Updates from Markus Mauhart <qwe123@chello.at>:

141 to avoid walking the list every time we want to add a new one.
142 Fixes Savannah bug #15533.
143 * filedef.h (struct file): Add a new LAST pointer.
145 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
146 the comparison. For 64-bits systems the result of the subtraction
147 might not fit into an int. Use comparison instead.
148 Fixes Savannah bug #15534.
150 * doc/make.texi: Update the chapter on writing commands to reflect
151 the changes made in 3.81 for backslash/newline and SHELL handling.

171 2006-01-21 Eli Zaretskii <eliz@gnu.org>
173 * remake.c (update_goal_chain): Set g->changed instead of
174 incrementing it, as it is only 8-bit wide, and could overflow if
175 many commands got started in update_file.
177 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
179 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

197 the shell is not sh.exe.
199 * job.c (create_batch_file): Renamed from create_batch_filename;
200 all callers changed. Don't close the temporary file; return its
201 file descriptor instead. New arg FD allows to return the file
203 (construct_command_argv_internal): Use _fdopen instead of fopen to
206 2006-01-04 Paul D. Smith <psmith@gnu.org>
208 * readme.vms: Updates for case-insensitive VMS file systems from

218 2006-01-03 Paul D. Smith <psmith@gnu.org>
220 * remake.c (update_file_1): Mark a prerequisite changed if it
223 * read.c (eval): Be sure to strip off trailing whitespace from the
224 prerequisites list properly. Also, initialize all fields in
225 struct dep when creating a new one.
227 2005-12-28 Paul D. Smith <psmith@gnu.org>
229 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
230 disable warnings for MSC.
231 Patch by Rob Tulloh <rtulloh@yahoo.com>.
233 2005-12-17 Eli Zaretskii <eliz@gnu.org>
235 * doc/make.texi (Execution): Add a footnote about changes in
236 handling of backslash-newline sequences. Mention the differences
237 on MS-DOS and MS-Windows.
239 * NEWS: More details about building the MinGW port and a pointer
240 to README.W32. Fix the section name that describes the new
241 backward-incompatible processing of backslash-newline sequences.
242 The special processing of SHELL set to "cmd" is only relevant to
243 MS-Windows, not MS-DOS.
245 2005-12-17 Eli Zaretskii <eliz@gnu.org>
247 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
248 to DWORD, to avoid compiler warnings.

266 garbage happened to be on the heap.
268 2005-12-12 Paul D. Smith <psmith@gnu.org>
270 * make.1: Fix some display errors and document all existing options.
271 Patch provided by Mike Frysinger <vapier@gentoo.org>.
273 2005-12-11 Paul D. Smith <psmith@gnu.org>
275 * implicit.c (pattern_search): If 2nd expansion is not set for
276 this implicit rule, replace the pattern with the stem directly,
277 and don't re-expand the variable list. Along with the other
278 .SECONDEXPANSION changes below, fixes bug #13781.
280 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
282 * implicit.c (pattern_search): Mark other files that this rule
283 builds as targets so that they are not treated as intermediates
284 by the pattern rule search algorithm. Fixes bug #13022.
286 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
288 * remake.c (notice_finished_file): Propagate the change of
289 modification time to all the double-colon entries only if

308 * read.c (record_files): Don't set deps flags if there are no deps.
309 * maintMakefile: We only need to build the templates when we are
310 creating a distribution, so don't do it for "all".
312 2005-10-24 Paul D. Smith <psmith@gnu.org>
314 Make secondary expansion optional: its enabled by declaring the
315 special target .SECONDEXPANSION.
317 * NEWS: Update information on second expansion capabilities.
318 * doc/make.texi (Secondary Expansion): Document the
319 .SECONDEXPANSION special target and its behavior.
320 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
321 prerequisite list was found in a static pattern rule.
322 (free_dep_chain): Declare a prototype.
323 * file.c (parse_prereqs): New function: break out some complexity
325 (expand_deps): If we aren't doing second expansion, replace % with
326 the stem for static pattern rules. Call the new function.
327 * filedef.h (parse_prereqs): Declare a prototype.
328 * implicit.c (pattern_search): Initialize the new staticpattern
330 * main.c (second_expansion): Declare a global variable to remember

334 * misc.c (free_dep_chain): New function: frees a struct dep list.
335 * read.c (read_all_makefiles): Initialize the staticpattern field.
336 (eval_makefile): Ditto.
337 (record_files): Check for the .SECONDEXPANSION target and set
338 second_expansion global if it's found.
339 Use the new free_dep_chain() instead of doing it by hand.
340 Set the staticpattern field for prereqs of static pattern targets.
342 2005-10-16 Paul D. Smith <psmith@gnu.org>
344 * main.c (main): Set CURDIR to be a file variable instead of a
345 default, so that values of CURDIR inherited from the environment
346 won't override the make value.
348 2005-09-26 Paul D. Smith <psmith@gnu.org>
350 * job.c (construct_command_argv_internal): If the line is empty
351 remember to free the temporary argv strings.
354 2005-09-16 Paul D. Smith <psmith@gnu.org>
356 * job.c (start_job_command): The noerror flag is a boolean (single
357 bit); set it appropriately.
358 Reported by Mark Eichin <eichin@metacarta.com>
360 2005-08-29 Paul D. Smith <psmith@gnu.org>
362 * function.c (func_error): On Windows, output from $(info ...)
363 seems to come in the wrong order. Try to force it with fflush().
365 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
367 * read.c (record_files): Move code that sets stem for static
368 pattern rules out of the if (!two_colon) condition so it is
369 also executed for two-colon rules. Fixes Savannah bug #13881.
371 2005-08-08 Paul D. Smith <psmith@gnu.org>
373 * make.h: Don't test that __STDC__ is non-0. Some compilers
374 (Windows for example) set it to 0 to denote "ISO C + extensions".
377 2005-08-07 Paul D. Smith <psmith@gnu.org>
379 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
380 conditional (slightly different version of a fix from Eli).
382 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
383 If make is running in parallel without -k and two jobs die in a
384 row, but not too close to each other, then make will quit without
385 waiting for the rest of the jobs to die.
387 * main.c (die): Don't reset err before calling reap_children() the
388 second time: we still want it to be in the error condition.
389 * job.c (reap_children): Use a static variable, rather than err,
390 to control whether or not the error message should be printed.
392 2005-08-06 Eli Zaretskii <eliz@gnu.org>
394 * w32/subproc/sub_proc.c: Include signal.h.
395 (process_pipe_io, process_file_io): Pass a pointer to a local
396 DWORD variable to GetExitCodeProcess. If the exit code is
397 CONTROL_C_EXIT, put SIGINT into pproc->signal.
399 * job.c [WINDOWS32]: Include windows.h.
400 (main_thread) [WINDOWS32]: New global variable.
401 (reap_children) [WINDOWS32]: Get the handle for the main thread
402 and store it in main_thread.
404 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
405 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
406 doing anything else. When we are done, close the main thread
407 handle and exit with status 130.

415 set sh_found and the value of default_shell, and report the
416 findings in debug mode.
418 * job.c (construct_command_argv_internal): Check unixy_shell, not
419 no_default_sh_exe, to decide whether to use Unixy or DOSish
422 * README.W32: Update with info about the MinGW build.
424 * build_w32.bat: Support MinGW.
426 * w32/subproc/build.bat: Likewise.
428 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
431 * function.c (windows32_openpipe): Fix format strings for printing
434 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
436 (start_job_command): Fix format string for printing the result of
438 (start_job_command) [WINDOWS32]: Do not define.
439 (exec_command): Fix format string for printing HANDLE args.
441 * main.c (handle_runtime_exceptions): Fix sprintf format strings
442 to avoid compiler warnings.
443 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
444 (Note: some of these fixes were submitted independently by J. Grant)
446 2005-07-30 J. Grant <jg@jguk.org>
448 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.

450 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
452 2005-07-15 Paul Smith <psmith@gnu.org>
454 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
455 we don't have a POSIX shell, then revert to the old
456 backslash-newline behavior (where they are stripped).
459 2005-07-08 Paul D. Smith <psmith@gnu.org>
461 * config.h.W32.template: Reorder to match the standard config.h,
462 for easier comparisons.
463 From J. Grant <jg@jguk.org>

468 arithmetic to avoid a warning.
469 * main.c (switches): Add full-fledged final initializer.
471 2005-07-06 Paul D. Smith <psmith@gnu.org>
473 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
474 * signame.c (strsignal): If we found _sys_siglist[] or
475 __sys_siglist[] use those instead of sys_siglist[].
476 From Albert Chin <china@thewrittenword.com>
478 2005-07-04 Paul D. Smith <psmith@gnu.org>
480 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
481 globfree(); set up to use the GNU versions.
482 From Martin Zinser <zinser@zinser.no-ip.info>
484 2005-07-03 Paul D. Smith <psmith@gnu.org>
486 From J. Grant <jg@jguk.org>:

496 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
497 declaration was checked but not present.
499 2005-06-27 Paul D. Smith <psmith@gnu.org>
501 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
502 to unsigned long. Fixes Savannah bug #13550.
504 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
505 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
506 Fixes Savannah bug #13551.
508 2005-06-26 Paul D. Smith <psmith@gnu.org>
510 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
511 it if ANSI_STRING is not set.
513 2005-06-25 Paul D. Smith <psmith@gnu.org>
515 * read.c (eval): If no filenames are passed to any of the
516 "include" variants, don't print an error.
517 * doc/make.texi (Include): Document this.
518 Fixes Savannah bug #1761.
520 * job.c (construct_command_argv_internal): Sanitize handling of
521 backslash/newline pairs according to POSIX: that is, keep the
522 backslash-newline in the command script, but remove a following
523 TAB character, if present. In the fast path, make sure that the
524 behavior matches what the shell would do both inside and outside
525 of quotes. In the slow path, quote the backslash and put a
526 literal newline in the string.
527 Fixes Savannah bug #1332.
528 * doc/make.texi (Execution): Document the new behavior and give
530 * NEWS: Make a note of the new behavior.
532 * make.h [WINDOWS32]: #include <direct.h>.
533 Fixes Savannah bug #13478.
535 * remake.c (name_mtime): If the stat() of a file fails and the -L
536 option was given and the file is a symlink, take the best mtime of
537 the symlink we can get as the mtime of the file and don't fail.
538 Fixes Savannah bug #13280.
540 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
541 If it's set, then don't stop on STOPCHARs or BLANKs if they're
542 inside a variable reference. Make this function static as it's
544 (eval): Call find_char_unquote() with IGNOREVARS set when we're
545 parsing an unexpanded line looking for semicolons.
546 Fixes Savannah bug #1454.
547 * misc.c (remove_comments): Move this to read.c and make it static
548 as it's only used there. Call find_char_unquote() with new arg.
549 * make.h: Remove prototypes for find_char_unquote() and
550 remove_comments() since they're static now.
552 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
553 its export flag and obtain its value. When we need to re-exec,
554 increment the value and add it into the environment.
555 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
556 * NEWS: Mention MAKE_RESTARTS.
557 * main.c (always_make_set): New variable. Change the -B option to
558 set this one instead.
559 (main): When checking makefiles, only set always_make_flag if
560 always_make_set is set AND the restarts flag is 0. When building
561 normal targets, set it IFF always_make_set is set.
562 (main): Avoid infinite recursion with -W, too: only set what-if
563 files to NEW before we check makefiles if we've never restarted
564 before. If we have restarted, set what-if files to NEW _after_ we
566 Fixes Savannah bug #7566:
568 2005-06-17 Paul D. Smith <psmith@gnu.org>
570 * default.c: Change VMS implicit rules to use $$$$ instead of $$
571 in the prerequisites list.
573 2005-06-12 Paul D. Smith <psmith@gnu.org>
575 Fix Savannah bug # 1328.
577 * configure.in: Check for atexit().
578 * misc.c (close_stdout): Test stdout to see if writes to it have
579 failed. If so, be sure to exit with a non-0 error code. Based on
580 code found in gnulib.
582 * main.c (main): Install close_stdout() with atexit().
584 2005-06-10 Paul D. Smith <psmith@gnu.org>
586 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
588 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
589 headers; make vmsWaitForChildren() static; extern vmsify().
590 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
591 Don't create child_execute_job() here (it's in vmsjobs.c).
592 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
594 2005-06-09 Paul D. Smith <psmith@gnu.org>
596 * variable.c (push_new_variable_scope): File variables point
597 directly to the global_setlist variable. So, inserting a new
598 scope in front of that has no effect on those variables: they
599 don't go through current_variable_set_list. If we're pushing a
600 scope and the current scope is global, push it "the other way" so
601 that the new setlist is in the global_setlist variable, and
602 next points to a new setlist with the global variable set.
603 (pop_variable_scope): Properly undo a push with the new
605 Fixes Savannah bug #11913.
607 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
609 * job.c (reap_children): Don't die of the command failed but
610 the dontcare flag is set. Fixes Savannah bug #13216.
612 * implicit.c (pattern_search): When creating a target from
613 an implicit rule match, lookup pattern target and set precious
614 flag in a newly created target. Fixes Savannah bug #13218.
616 2005-05-13 Paul D. Smith <psmith@gnu.org>
618 Implement "if... else if... endif" syntax.
620 * read.c (eval): Push all checks for conditional words ("ifeq",
621 "else", etc.) down into the conditional_line() function.
622 (conditional_line): Rework to allow "else if..." clause. New
623 return value -2 for lines which are not conditionals. The
624 ignoring flag can now also be 2, which means "already parsed a
625 true branch". If that value is seen no other branch of this
626 conditional can be considered true. In the else parsing if there
627 is extra text after the else, invoke conditional_line()
628 recursively to see if it's another conditional. If not, it's an
629 error. If so, raise the conditional value to this level instead
630 of creating a new conditional nesting level. Special check for
631 "else" and "endif", which aren't allowed on the "else" line.
632 * doc/make.texi (Conditional Syntax): Document the new syntax.
634 2005-05-09 Paul D. Smith <psmith@gnu.org>
636 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
637 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
638 recurses to the w32 directory, even on non-Windows systems. Use
639 the method suggested in the automake manual.
640 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
641 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
643 2005-05-07 Paul D. Smith <psmith@gnu.org>
645 * main.c (die): If we're dying with a fatal error (not that a
646 command has failed), write back any leftover tokens before we go.
648 * job.c (set_child_handler_action_flags): If there are jobs
649 waiting for the load to go down, set an alarm to go off in 1
650 second. This allows us to wake up from a potentially long-lasting
651 read() and start a new job if the load has gone down. Turn it off
653 (job_noop): Dummy signal handler function.
654 (new_job): Invoke it with the new semantics.
656 * docs/make.texi: Document secondary expansion. Various cleanups
659 2005-05-03 Paul D. Smith <psmith@gnu.org>
661 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
662 the targets which are to ultimately be made are called "goals";
663 see the GNU make manual. Also, MAKECMDGOALS, etc.
665 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
666 .DEFAULT_GOAL, and default_target_name to default_goal_name.
667 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
669 2005-05-02 Paul D. Smith <psmith@gnu.org>
671 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
672 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
673 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
674 functions to vmsjobs.c. #include it into jobs.c.
676 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
677 jobserver tokens. I found that this happens when an exported
678 recursive variable contains a $(shell ...) function reference: in
679 this situation we could "forget" to write back a token.
681 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
682 we have. It's not reliable to depend on the number of children in
683 our linked list so keep a separate count.
684 (new_job): Check jobserver_tokens rather than children &&
685 waiting_jobs. Increment jobserver_tokens when we get one.
686 (free_child): If jobserver_tokens is 0, internal error. If it's
687 >1, write a token back to the jobserver pipe (we don't write a
688 token for the "free" job). Decrement jobserver_tokens.
690 * main.c: Add variable master_job_slots.
691 (main): Set it to hold the number of jobs requested if we're the
692 master process, when using the jobserver.
693 (die): Sanity checks: first test jobserver_tokens to make sure
694 this process isn't holding any tokens we didn't write back.
695 Second, if master_job_slots is set count the tokens left in the
696 jobserver pipe and ensure it's the same as master_job_slots (- 1).
698 2005-04-24 Paul D. Smith <psmith@gnu.org>
700 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
701 with -l# can lose jobserver tokens, because waiting jobs are not
702 consulted properly when checking for the "free" token.
704 * job.c (free_child): Count waiting_jobs as having tokens.
705 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
706 handle jobs waiting for the load to drop.
708 2005-04-23 Paul D. Smith <psmith@gnu.org>
710 * main.c (main): Be careful to not core if a variable setting in
711 the environment doesn't contain an '='. This is illegal but can
712 happen in broken setups.
713 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
715 2005-04-12 Paul D. Smith <psmith@gnu.org>
717 The second expansion feature causes significant slowdown. Timing
718 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
719 read the makefile before the feature, to 11+s to do the same
720 operations after the feature. Additionally, memory usage
721 increased drastically. To fix this I added some intelligence that
722 avoids the overhead of the second expansion unless it's required.
724 * dep.h: Add a new boolean field, need_2nd_expansion.
726 * read.c (eval): When creating the struct dep for the target,
727 check if the name contains a "$"; if so set need_2nd_expansion to 1.
728 (record_files): If there's a "%" in a static pattern rule, it gets
729 converted to "$*" so set need_2nd_expansion to 1.
731 * file.c (expand_deps): Rework to be more efficient. Only perform
732 initialize_file_variables(), set_file_variables(), and
733 variable_expand_for_file() if the need_2nd_expansion is set.
735 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
736 (pattern_search): Ditto.
737 * main.c (handle_non_switch_argument): Ditto.
739 * read.c (read_all_makefiles): Ditto.
740 (eval_makefile): Ditto.
742 2005-04-07 Paul D. Smith <psmith@gnu.org>
744 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
745 * variable.c (sync_Path_environment): Ditto.
746 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
748 * main.c (main): Define the .FEATURES variable.
749 * NEWS: Announce .FEATURES.
750 * doc/make.texi (Special Variables): Document .FEATURES.
752 * remake.c (check_dep): If a file is .PHONY, update it even if
753 it's marked intermediate. Fixes Savannah bug #12331.
755 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
757 * file.c (expand_deps): Factor out the second expansion and
758 prerequisite line parsing logic from snap_deps().
760 * file.c (snap_deps): Use expand_deps(). Expand and parse
761 prerequisites of the .SUFFIXES special target first. Fixes
764 2005-03-13 Paul D. Smith <psmith@gnu.org>
766 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
769 2005-03-11 Paul D. Smith <psmith@gnu.org>
771 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
772 available, not undefined (from Earnie Boyd).
774 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
776 * implicit.c (pattern_search): Mark an intermediate target as
777 precious if it happened to be a prerequisite of some (other)
778 target. Fixes Savannah bug #12267.
780 2005-03-09 Paul D. Smith <psmith@gnu.org>
782 * read.c (eval_makefile): Add alloca(0).
783 (eval_buffer): Ditto.
785 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
787 * main.c (main): Use o_file instead of o_default when defining
788 the .DEFAULT_TARGET special variable.
789 * read.c (eval): Use define_variable_global() instead of
790 define_variable() when setting new value for the .DEFAULT_TARGET
791 special variable. Fixes Savannah bug #12266.
793 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
795 * imlicit.c (pattern_search): Mark files for which an implicit
796 rule has been found as targets. Fixes Savannah bug #12202.
798 2005-03-04 Paul D. Smith <psmith@gnu.org>
801 * doc/make.texi (Automatic Variables): Document $|.
803 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
805 * read.c (record_files): Instead of substituting % with
806 actual stem value in dependency list replace it with $*.
807 This fixes stem triple expansion bug.
809 * implicit.c (pattern_search): Copy stem to a separate
810 buffer and make it a properly terminated string. Assign
811 this buffer instead of STEM (which is not terminated) to
812 f->stem. Instead of substituting % with actual stem value
813 in dependency list replace it with $*. This fixes stem
814 triple expansion bug.
816 2005-03-01 Paul D. Smith <psmith@gnu.org>
818 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
819 on Windows, as it takes a handle not a pid. Just exit.
820 Fix from patch #3679, provided by Alessandro Vesely.
822 * configure.in: Update check for sys_siglist[] from autoconf manual.
823 * signame.c (strsignal): Update to use the new autoconf macro.
825 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
827 * read.c (record_files): Add a check for the list of prerequisites
828 of a static pattern rule being empty. Fixes Savannah bug #12180.
830 2005-02-28 Paul D. Smith <psmith@gnu.org>
832 * doc/make.texi (Text Functions): Update docs to allow the end
833 ordinal for $(wordlist ...) to be 0.
834 * function.c (func_wordlist): Fail if the start ordinal for
835 $(wordlist ...) is <1. Matches documentation.
836 Resolves Savannah support request #103195.
838 * remake.c (update_goal_chain): Fix logic for stopping in -q:
839 previously we were stopping when !-q, exactly the opposite. This
840 has been wrong since version 1.34, in 1994!
841 (update_file): If we got an error don't break out to run more
842 double-colon rules: just return immediately.
843 Fixes Savannah bug #7144.
845 2005-02-27 Paul D. Smith <psmith@gnu.org>
847 * misc.c (end_of_token): Make argument const.
848 * make.h: Update prototype.
850 * function.c (abspath, func_realpath, func_abspath): Use
851 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
852 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
853 * read.c (record_files): Ditto.
854 * variable.c (do_variable_definition): Ditto.
856 * function.c (func_error): Create a new function $(info ...) that
857 simply prints the message to stdout with no extras.
858 (function_table_init): Add new function to the table.
859 * NEWS: Add $(info ...) reference.
860 * doc/make.texi (Make Control Functions): Document it.
862 New feature: if the system supports symbolic links, and the user
863 provides the -L/--check-symlink-time flag, then use the latest
864 mtime between the symlink(s) and the target file.
866 * configure.in (MAKE_SYMLINKS): Check for lstat() and
867 readlink(). If both are available, define MAKE_SYMLINKS.
868 * main.c: New variable: check_symlink_flag.
869 (usage): Add a line for -L/--check-symlink-times to the help string.
870 (switches): Add -L/--check-symlink-times command line argument.
871 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
872 print a warning and disable it again.
873 * make.h: Declare check_symlink_flag.
874 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
875 if the file is a symlink then check each link in the chain and
876 choose the NEWEST mtime we find as the mtime for the file. The
877 newest mtime might be the file itself!
878 * NEWS: Add information about this new feature.
879 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
881 Avoid core dumps described in Savannah bug # 12124:
883 * file.c: New variable snapped_deps remember whether we've run
886 * filedef.h: Extern it.
887 * read.c (record_files): Check snapped_deps; if it's set then
888 we're trying to eval a new target/prerequisite relationship from
889 within a command script, which we don't support. Fatal.
891 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
893 Implementation of the .DEFAULT_TARGET special variable.
895 * read.c (eval): If necessary, update default_target_name when
897 * read.c (record_files): Update default_target_file if
898 default_target_name has changed.
899 * main.c (default_target_name): Define.
900 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
901 default_target_name is set use default_target_file as a root
903 * filedef.h (default_target_name): Declare.
904 * dep.h (free_dep_chain):
905 * misc.c (free_dep_chain): Change to operate on struct nameseq
906 and change name to free_ns_chain.
907 * file.c (snap_deps): Update to use free_ns_chain.
909 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
911 Implementation of the second expansion in explicit rules,
912 static pattern rules and implicit rules.
914 * read.c (eval): Refrain from chopping up rule's dependencies.
915 Store them in a struct dep as a single dependency line. Remove
916 the code that implements SySV-style automatic variables.
918 * read.c (record_files): Adjust the code that handles static
919 pattern rules to expand all percents instead of only the first
920 one. Reverse the order in which dependencies are stored so that
921 when the second expansion reverses them again they appear in
922 the makefile order (with some exceptions, see comments in
923 the code). Remove the code that implements SySV-style automatic
926 * file.c (snap_deps): Implement the second expansion and chopping
927 of dependency lines for explicit rules.
929 * implicit.c (struct idep): Define an auxiliary data type to hold
930 implicit rule's dependencies after stem substitution and
933 * implicit.c (free_idep_chain): Implement.
935 * implicit.c (get_next_word): Implement helper function for
936 parsing implicit rule's dependency lines into words taking
937 into account variable expansion requests. Used in the stem
940 * implicit.c (pattern_search): Implement the second expansion
941 for implicit rules. Also fixes bug #12091.
943 * commands.h (set_file_variables): Declare.
944 * commands.c (set_file_variables): Remove static specifier.
946 * dep.h (free_dep_chain): Declare.
947 * misc.c (free_dep_chain): Implement.
949 * variable.h (variable_expand_for_file): Declare.
950 * expand.c (variable_expand_for_file): Remove static specifier.
952 * make.h (strip_whitespace): Declare.
953 * function.c (strip_whitespace): Remove static specifier.
955 2005-02-26 Paul D. Smith <psmith@gnu.org>
957 * main.c (main): Check for ferror() when reading makefiles from stdin.
958 Apparently some shells in Windows don't close pipes properly and
961 2005-02-24 Jonathan Grant <jg@jguk.org>
963 * configure.in: Add MinGW configuration options, and extra w32 code
965 * Makefile.am: Add MinGW configuration options, and extra w32 code
967 * main.c: Determine correct program string (after last \ without .exe).
968 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
970 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
971 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
972 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
975 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
977 * function.c (func_shell): When initializing error_prefix, check
978 that reading file name is not null. This fixes long-standing
979 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
981 2005-02-09 Paul D. Smith <psmith@gnu.org>
983 * maintMakefile: Update the CVS download URL to simplify them.
984 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
985 downloading the .texi files from Savannah now.
987 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
989 * main.c (handle_non_switch_argument): Only add variables to
990 command_variables if they're not already there: duplicate settings
991 waste space and can be confusing to read.
993 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
994 this header is never included by non-WINDOWS32 code, and it
995 requires <config.h> to define which isn't always included first.
997 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
998 testing MINGW32 versions.
1000 * main.c (log_working_directory): flush stdout to be sure the WD
1001 change is printed before any stderr messages show up.
1003 2005-02-01 Paul D. Smith <psmith@gnu.org>
1005 * maintMakefile (po_repo): Update the GNU translation site URL.
1007 2004-12-01 Paul D. Smith <psmith@gnu.org>
1009 * main.c (main): Change char* env_shell to struct variable shell_var.
1010 * variable.c (target_environment): Use new shell_var.
1012 2004-11-30 Paul D. Smith <psmith@gnu.org>
1014 * configure.in: The old way we avoided creating build.sh from
1015 build.sh.in before build.sh.in exists doesn't work anymore; we
1016 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1017 the help!). This also keeps automake from complaining.
1018 * Makefile.am (README): Add a dummy target so automake won't
1019 complain that this file doesn't exist when we checkout from CVS.
1020 * maintMakefile (.dep_segment): Rewrite this rule since newer
1021 versions of automake don't provide DEP_FILES.
1023 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1025 Implementation of `realpath' and `abspath' built-in functions.
1027 * configure.in: Check for realpath.
1028 * function.c (abspath): Return an absolute file name that does
1029 not contain any `.' or `..' components, nor repeated `/'.
1030 * function.c (func_abspath): For each name call abspath.
1031 * function.c (func_realpath): For each name call realpath
1032 from libc or delegate to abspath if realpath is not available.
1033 * doc/make.texi (Functions for File Names): Document new functions.
1034 * doc/make.texi (Quick Reference): Ditto.
1036 2004-11-28 Paul D. Smith <psmith@gnu.org>
1038 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1039 arguments. Fixes bug #10252.
1041 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1043 * main.c (main): Set SHELL to v_noexport by default. Remember the
1044 original environment setting of SHELL in the env_shell variable.
1045 * main.h: Export new env_shell variable.
1046 * variable.c (target_environment): If we find a v_noexport
1047 variable for SHELL, add a SHELL variable with the env_shell value.
1048 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1049 * doc/make.texi (Variables/Recursion): Ditto.
1051 2004-11-28 Paul D. Smith <psmith@gnu.org>
1053 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1054 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1055 Patch by Alessandro Vesely.
1057 2004-11-12 Paul D. Smith <psmith@gnu.org>
1059 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1060 the command line if it's inside a string.
1061 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1063 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1065 * function.c (func_lastword): New function: return last word
1066 from the list of words.
1067 * doc/make.texi: Document $(lastword ). Fix broken links in
1068 Quick Reference section.
1070 2004-10-06 Paul D. Smith <psmith@gnu.org>
1072 Apply patch from Alessandro Vesely, provided with bug # 9748.
1073 Fix use of tmpnam() to work with Borland C.
1075 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1076 construction of a temporary filename, and call new function
1077 create_batch_filename().
1078 (create_batch_filename) [WINDOWS32]: New function to create a
1081 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1083 * read.c (record_target_var): Expand simple pattern-specific
1085 * variable.c (initialize_file_variables): Do not expand simple
1086 pattern-specific variable.
1088 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1090 * remake.c (update_file_1): When rebuilding makefiles inherit
1091 dontcare flag from a target that triggered update.
1093 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1095 * variable.c (initialize_file_variables): Mark pattern-specific
1096 variable as a per-target and copy export status.
1098 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1100 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1102 * implicit.c (pattern_search): When considering an implicit rule's
1103 prerequisite check that it is actually a target rather then
1104 just an entry in the file hashtable.
1106 2004-09-21 Paul D. Smith <psmith@gnu.org>
1108 * read.c (readstring): Fix some logic errors in backslash handling.
1109 (eval): Remove some unnecessary processing in buffer handling.
1110 (record_target_var): Assert that parse_variable_definition() succeeded.
1111 Reported by: Markus Mauhart <qwe123@chello.at>.
1113 * misc.c: Removed the sindex() function. All instances of this
1114 function were trivially replaceable by the standard strstr()
1115 function, and that function will always have better (or certainly
1116 no worse) performance than the very simple-minded algorithm
1117 sindex() used. This can matter with complex makefiles.
1118 * make.h: Remove the prototype for sindex().
1119 * function.c (subst_expand): Convert sindex() call to strstr().
1120 This means we no longer need to track the TLEN value so remove that.
1121 (func_findstring): Convert sindex() to strstr().
1122 * commands.c (chop_commands): Convert sindex() calls to strstr().
1123 Suggested by: Markus Mauhart <qwe123@chello.at>.
1125 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1126 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1127 If SHELL is set to CMD.EXE then assume it's batch-mode and
1128 non-unixy. I wrote the code differently from the patch, though,
1129 to make it safer. This also resolves bug #9174.
1131 2004-09-20 Paul D. Smith <psmith@gnu.org>
1133 * expand.c (variable_expand_string): Modify to invoke
1134 patsubst_expand() instead of subst_expand(); the latter didn't
1135 handle suffix patterns correctly.
1136 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1137 was used only from variable_expand_string() and is no longer used
1139 (func_subst): Ditto, on call to subst_expand().
1140 (patsubst_expand): Require the percent pointers to point to the
1141 character after the %, not to the % itself.
1142 * read.c (record_files): New call criteria for patsubst_expand().
1143 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1144 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1146 2004-09-19 Paul D. Smith <psmith@gnu.org>
1148 * function.c (subst_expand): Fix a check in by_word: look for a
1149 previous blank if we're beyond the beginning of the string, not
1150 the beginning of the word.
1151 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1153 2004-05-16 Paul D. Smith <psmith@gnu.org>
1155 * remake.c (update_goal_chain): Change the argument specifying
1156 whether we're rebuilding makefiles to be a global variable,
1157 REBUILDING_MAKEFILES.
1158 (complain): Extract the code that complains about no rules to make
1159 a target into a separate function.
1160 (update_file_1): If we tried to rebuild a file during the makefile
1161 rebuild phase and it was dontcare, then no message was printed.
1162 If we then try to build the same file during the normal build,
1163 print a message this time.
1164 (remake_file): Don't complain about un-remake-able files when
1165 we're rebuilding makefiles.
1167 2004-05-11 Paul D. Smith <psmith@gnu.org>
1169 * job.c (construct_command_argv_internal): OS/2 patches from
1170 Andreas Buening <andreas.buening@nexgo.de>.
1172 2004-05-10 Paul D. Smith <psmith@gnu.org>
1174 * remake.c (update_file): Don't walk the double-colon chain unless
1175 this is a double-colon rule. Fix suggested by Boris Kolpackov
1176 <boris@kolpackov.net>.
1178 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1179 * readme.vms: New section describing OpenVMS support and issues.
1180 * default.c (default_variables): Add support for IA64.
1181 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1182 without some privilege aborts make with the error
1183 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1184 pressing Ctrl+Y and the input device is no terminal. The change
1185 catches this error and just continues.
1187 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1189 2004-04-25 Paul D. Smith <psmith@gnu.org>
1191 * commands.c (set_file_variables): Set $< properly in the face of
1192 order-only prerequisites.
1193 Patch from Boris Kolpackov <boris@kolpackov.net>
1195 2004-04-21 Bob Byrnes <byrnes@curl.com>
1197 * main.c (main): Notice failures to remake makefiles.
1199 2004-03-28 Paul D. Smith <psmith@gnu.org>
1201 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1203 * job.c: No default shell for RISC OS.
1204 (load_too_high): Hard-code the return to 1.
1205 (construct_command_argv_internal): No sh_chars or sh_cmds.
1206 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1208 2004-03-20 Paul D. Smith <psmith@gnu.org>
1210 * variable.c (do_variable_definition): Don't append from the
1211 global set if a previous non-appending target-specific variable
1212 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1215 * expand.c (reference_variable): Don't give up on variables with
1216 no value that have the target-specific append flag set: they might
1217 have a value after all. Reported by Oliver Schmidt
1218 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1219 <nikulin@dx1cmd.inp.nsk.su>.
1221 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1222 refer to absolute pathnames in directories that don't exist: some
1223 portion of the makefile could create those directories before we
1224 match the pattern. Fixes bugs #775 and #108.
1226 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1228 * main.c (main): Free makefile_mtimes if we have any.
1229 * README.W32.template: Update documentation for the current status
1230 of the MS-Windows port.
1231 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1232 environment variable is sometimes already defined which causes the
1234 * main.c (debug_signal_handler): Only define this function if
1235 SIGUSR1 is available.
1237 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1239 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1240 * README.OS2.template: Documentation updates.
1241 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1242 link line for safety.
1243 * maintMakefile (build.sh.in): Remove an extraneous ")".
1244 * job.c (child_execute_job): Close saved FDs.
1245 * job.c (exec_command) [OS/2]: exec_command(): If the command
1246 can't be exec'ed and if the shell is not Unix-sh, then try again
1247 with argv = { "cmd", "/c", ... }. Normally, this code is never
1248 reached for the cmd shell unless the command really doesn't exist.
1249 (construct_command_argv_internal) [OS/2]: The code for cmd
1250 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1251 The CMD builtin commands are case insensitive so use strcasecmp().
1253 2004-03-19 Paul D. Smith <psmith@gnu.org>
1255 * read.c (do_define): Re-order line counter increment so the count
1256 is accurate (we were losing one line per define). Reported by
1257 Dave Yost <Dave@Yost.com>.
1259 2004-03-06 Paul D. Smith <psmith@gnu.org>
1261 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1263 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1264 * misc.c (message,error,fatal): Ditto.
1265 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1266 * config.h.W32.template: Ditto.
1267 * config.h-vms.template: Ditto.
1268 * config.ami.template: Ditto.
1270 2004-03-04 Paul D. Smith <psmith@gnu.org>
1272 * README.template: Add a note about broken /bin/sh on SunOS
1273 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1275 * misc.c (message, error, fatal): Don't use "..." if we're using
1276 varargs. ansi2knr should handle this but it doesn't work: it
1277 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1278 done. On many systems (SunOS for example) va_dcl is a #define.
1279 So, force the use of the non-"..." version on pre-ANSI compilers.
1281 * maintMakefile (sign-dist): Create some rules to help automate
1282 the new GNU ftp upload method.
1284 2004-02-24 Paul D. Smith <psmith@gnu.org>
1286 * config.h.W32.template: Add HAVE_STDARG_H
1287 * config.h-vms.template: Ditto.
1288 * config.ami.template: Ditto.
1290 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1292 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1293 * build_w32.bat: Remove extra "+".
1295 2004-02-23 Paul D. Smith <psmith@gnu.org>
1297 * make.h: Create an UNUSED macro to mark unused parameters.
1298 * (many): Clean up warnings by applying UNUSED, fixing
1299 signed/unsigned incompatibilities, etc.
1301 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1303 * filedef.h: Name the command_state enumeration.
1304 * file.c (set_command_state): Use the enumeration in the function
1307 * configure.in: Explicitly set SET_MAKE to empty, to disable
1308 MAKE=make even when no make already exists. Fix bug #3823.
1310 2004-02-22 Paul D. Smith <psmith@gnu.org>
1312 * maintMakefile: Perl script to clean up all non-CVS files. Use
1313 it on all the subdirectories for the cvs-clean target.
1315 * main.c (decode_switches): Require non-empty strings for all our
1316 string command-line options. Fixes Debian bug # 164165.
1318 * configure.in: Check for stdarg.h and varargs.h.
1319 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1320 for printing messages.
1321 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1326 A number of patches for OS/2 support from Andreas Buening
1327 <andreas.buening@nexgo.de>:
1329 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1330 disable the SIGCHLD handler.
1331 (reap_children) [OS/2]: Remove special handling of job_rfd.
1332 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1333 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1334 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1335 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1336 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1339 2004-02-21 Paul D. Smith <psmith@gnu.org>
1341 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1342 <mail@kristov.de> reports that if process_begin() fails we don't
1343 handle the error condition correctly in all cases.
1344 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1345 to have a newline on the message.
1347 * job.c (construct_command_argv_internal): Add "test" to UNIX
1348 sh_cmds[]. Fixes Savannah bug # 7606.
1350 2004-02-04 Paul D. Smith <psmith@gnu.org>
1352 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1353 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1354 Hartmut Becker <Hartmut.Becker@hp.com>.
1356 2004-01-21 Paul D. Smith <psmith@gnu.org>
1358 * job.c (load_too_high): Implement an algorithm to control the
1359 "thundering herd" problem when using -l to control job creation
1360 via the load average. The system only recomputes the load once a
1361 second but we can start many jobs in a second. To solve this we
1362 keep track of the number of jobs started in the last second and
1363 apply a weight to try to guess what a correct load would be.
1364 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1365 Also fixes bug #4693.
1366 (reap_children): Decrease the job count for this second.
1367 (start_job_command): Increase the job count for this second.
1369 * read.c (conditional_line): Expand the text after ifn?def before
1370 checking to see if it's a single word. Fixes bug #7257.
1372 2004-01-09 Paul D. Smith <psmith@gnu.org>
1374 * file.c (print_file): Recurse to print all targets in
1375 double-colon rules. Fixes bug #4518, reported (with patch) by
1376 Andrew Chatham <chatham@google.com>.
1378 2004-01-07 Paul D. Smith <psmith@gnu.org>
1380 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1381 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1382 AC_FUNC_SETVBUF_REVERSED.
1384 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1385 (MAKE Variable): Fix Savannah bug #4898.
1387 * job.c (construct_command_argv_internal): Add "!" to the list of
1388 shell escape chars. POSIX sh allows it to appear before a
1389 command, to negate the exit code. Fixes bug #6404.
1391 * implicit.c (pattern_search): When matching an implicit rule,
1392 remember which dependencies have the ignore_mtime flag set.
1393 Original fix provided in Savannah patch #2349, by Benoit
1394 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1396 2003-11-22 Paul D. Smith <psmith@gnu.org>
1398 * README.W32.template (Outputs): Clarification on -j with
1399 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1402 2003-11-02 Paul D. Smith <psmith@gnu.org>
1404 * function.c (func_if): Strip all the trailing whitespace from the
1405 condition, then don't expand it. Fixed bug # 5798.
1407 * expand.c (recursively_expand_for_file): If we're expanding a
1408 variable with no file context, then use the variable's context.
1411 2003-10-21 Paul D. Smith <psmith@gnu.org>
1413 * main.c (log_working_directory): Add newlines to printf()s.
1415 * README.cvs: Add a note to ignore warnings during autoreconf.
1417 * maintMakefile (po_repo): Set a new URL for PO file updates.
1418 (get-config/config.guess get-config/config.sub): Get these files
1419 from the Savannah config project instead of ftp.gnu.org.
1421 2003-10-05 Paul Eggert <eggert@twinsun.com>
1423 * main.c (main): Avoid potential subscript error if environ has
1426 2003-08-22 Paul D. Smith <psmith@gnu.org>
1428 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1429 systems which don't yet implement the C89 standard :-/.
1431 2003-07-18 Paul D. Smith <psmith@gnu.org>
1433 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1434 [WINDOWS32]: Initialize hash.
1436 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1438 * dir.c (read_dirstream): Provide a workaround for broken versions of
1439 the MinGW dirent structure.
1441 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1443 * w32/include/dirent.h: Add __MINGW32__ filter.
1445 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1447 * make.h: Add global declaration of *make_host.
1448 * main.c (print_usage): Remove local declaration of *make_host.
1449 (print_version): Display "This program built for ..." after Copyright
1452 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1454 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1455 execution of "makeinfo --html make.texi".
1457 2003-04-30 Paul D. Smith <psmith@gnu.org>
1459 * build.template: Make some changes to maybe allow this script to
1460 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1462 * README.OS2.template: New file for OS/2 support. Original
1463 contributed by Andreas Buening.
1464 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1467 2003-04-19 Paul D. Smith <psmith@gnu.org>
1469 Fix bug #1405: allow a target to match multiple pattern-specific
1472 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1473 variable.c, where they've always belonged.
1474 * rule.h: Move the prototypes and struct pattern_var as well.
1475 * variable.c (initialize_file_variables): Invoke
1476 lookup_pattern_var() in a loop, until no more matches are found.
1477 If a match is found, create a new variable set for the target's
1478 pattern variables. Then merge the contents of each matching
1479 pattern variable set into the target's pattern variable set.
1480 (lookup_pattern_var): Change this function to be usable
1481 in a loop. It takes a starting position: if NULL, start at the
1482 beginning; if non-NULL, start with the pattern variable after that
1483 position, and return the next matching pattern.
1484 (create_pattern_var): Create a unique instance of
1485 pattern-specific variables for every definition in the makefile.
1486 Don't combine the same pattern together. This allows us to
1487 process the variable handling properly even when the same pattern
1488 is used multiple times.
1489 (parse_variable_definition): New function: break out the parsing
1490 of a variable definition line from try_variable_definition.
1491 (try_variable_definition): Call parse_variable_definition to
1493 (print_variable_data_base): Print out pattern-specific variables.
1494 * variable.h (struct variable): Remember when a variable is
1495 conditional. Also remember its flavor.
1496 (struct pattern_var): Instead of keeping a variable set, we just
1497 keep a single variable for each pattern.
1498 * read.c (record_target_var): Each pattern variable contains only a
1499 single variable, not a set, so create it properly.
1500 * doc/make.texi (Pattern-specific): Document the new behavior.
1502 2003-04-17 Paul D. Smith <psmith@gnu.org>
1504 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1505 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1506 file/directory naming rules for VMS so I can't tell whether this
1509 2003-04-09 Paul D. Smith <psmith@gnu.org>
1511 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1512 DOS-style pathnames: backslash separators and drive specifiers.
1514 2003-03-28 Paul D. Smith <psmith@gnu.org>
1516 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1517 the intermediate flag on all targets. Fixes bug #2515.
1519 2003-03-24 Paul D. Smith <psmith@gnu.org>
1521 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1522 Upgrade to autoconf 2.57 and automake 1.7.3.
1524 * job.c: More OS/2 changes from Andreas Buening.
1526 * file.c (print_file): Fix variable initialization.
1529 * remake.c (notice_finished_file):
1531 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1532 some calls (like readdir()) return NULL in valid situations
1533 without resetting errno. Fixes bug #2846.
1535 2003-02-25 Paul D. Smith <psmith@gnu.org>
1537 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1539 * job.c (_is_unixy_shell) [OS/2]: New function.
1540 Set default shell to /bin/sh.
1541 (reap_children): Close the job_rfd pipe here since we don't use a
1543 (set_child_handler_action_flags): define this to empty on OS/2.
1544 (start_job_command): Close the jobserver pipe and use
1545 child_execute_job() instead of fork/exec.
1546 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1547 rather than exec'ing, then reconfigure stdin/stdout.
1548 (exec_command): Rewrite to use spawn instead of exec. Return the
1551 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1552 in DOS. Handle the TEMP environment variable as in DOS. Don't
1553 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1554 use -j in DOS mode. Use child_execute_job() instead of
1557 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1560 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1561 prototypes that return values.
1563 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1565 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1566 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1568 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1571 2003-02-24 Paul D. Smith <psmith@gnu.org>
1573 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1574 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1575 (child_execute_job) [VMS]: Handle error status properly.
1576 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1578 * function.c (func_shell): Use EINTRLOOP() while reading from the
1579 subshell pipe (Fixes bug #2502).
1580 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1582 * main.c (main): Ditto.
1584 2003-01-30 Paul D. Smith <psmith@gnu.org>
1586 * read.c (eval): eval() was not fully reentrant, because the
1587 collapsed buffer was static. Change it to be an automatic
1588 variable so that eval() can be invoked recursively.
1590 (eval): Apply patch # 1022: fix memory reference error on long
1591 target-specific variable lines.
1592 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1594 * function.c (check_numeric): Combine the is_numeric() function
1595 into this function, since it's only called from one place.
1596 Constify this function. Have it print the incorrect string in the
1597 error message. Fixes bug #2407.
1598 (strip_whitespace): Constify.
1599 (func_if): Constify.
1600 * expand.c (expand_argument): Constify.
1602 2003-01-29 Paul D. Smith <psmith@gnu.org>
1604 Fix bug # 2169, also reported by other people on various systems.
1606 * make.h: Some systems, such as Solaris and PTX, do not fully
1607 implement POSIX-compliant SA_RESTART functionality; important
1608 system calls like stat() and readdir() can still fail with EINTR
1609 even if SA_RESTART has been set on the signal handler. So,
1610 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1611 EINTR for system calls which return -1 or 0 (NULL), respectively,
1613 Also, remove the old atomic_stat()/atomic_readdir() and
1614 HAVE_BROKEN_RESTART handling.
1616 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1618 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1619 * remake.c (touch_file): Ditto.
1621 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1622 * read.c (construct_include_path): Ditto.
1623 * remake.c (name_mtime): Ditto.
1624 * vpath.c (selective_vpath_search): Ditto.
1625 * dir.c (find_directory): Ditto.
1626 (local_stat): Ditto.
1627 (find_directory): Use ENULLLOOP() to wrap opendir().
1628 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1630 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1631 atomic_readdir() handling.
1633 2003-01-22 Paul D. Smith <psmith@gnu.org>
1635 * function.c (func_call): Fix Bug #1744. If we're inside a
1636 recursive invocation of $(call ...), mask any of the outer
1637 invocation's arguments that aren't used by this one, so that this
1638 invocation doesn't "inherit" them accidentally.
1640 2002-12-05 Paul D. Smith <psmith@gnu.org>
1642 * function.c (subst_expand): Valery Khamenia reported a
1643 pathological performance hit when doing substitutions on very
1644 large values with lots of words: turns out we were invoking
1645 strlen() a ridiculous number of times. Instead of having each
1646 call to sindex() call strlen() again, keep track of how much of
1647 the text we've seen and pass the length to sindex().
1649 2002-11-19 Paul D. Smith <psmith@gnu.org>
1651 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1654 2002-11-16 Paul D. Smith <psmith@gnu.org>
1656 * NMakefile.template (OBJS): Add hash.c object file.
1657 * SMakefile.template (srcs): Ditto.
1658 * Makefile.ami (objs): Ditto.
1659 * build_w32.bat: Ditto.
1661 * Makefile.DOS.template: Remove extra dependencies.
1663 2002-10-25 Paul D. Smith <psmith@gnu.org>
1665 * expand.c (install_variable_buffer): New function. Install a new
1666 variable_buffer context and return the previous one.
1667 (restore_variable_buffer): New function. Free the current
1668 variable_buffer context and put a previously saved one back.
1669 * variable.h: Prototypes for {install,restore}_variable_buffer.
1670 * function.c (func_eval): Push a new variable_buffer context
1671 before we eval, then restore the old one when we're done.
1674 * read.c (install_conditionals): New function. Install a new
1675 conditional context and return the previous one.
1676 (restore_conditionals): New function. Free the current
1677 conditional context and put a previously saved one back.
1678 (eval): Use the {install,restore}_conditionals for "include"
1680 (eval_buffer): Use {install,restore}_conditionals to preserve the
1681 present conditional state before we evaluate the buffer.
1684 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1686 (Recursion): Add a variable index entry for CURDIR.
1688 * README.cvs: Update to appropriate versions.
1689 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1690 don't need to copy loadavg.c: automake is smart enough to create
1691 it for me. Still have a bug in automake related to ansi2knr tho.
1693 2002-10-14 Paul D. Smith <psmith@gnu.org>
1695 * remake.c (notice_finished_file): Only touch targets if they have
1696 at least one command (as per POSIX). Resolve Bug #1418.
1698 * *.c: Convert to using ANSI C-style function definitions.
1699 * Makefile.am: Enable the ansi2knr feature of automake.
1700 * configure.in: ditto.
1702 2002-10-13 Paul D. Smith <psmith@gnu.org>
1704 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1705 for automatic variable values like $^, etc. In the case of very
1706 large lists of prerequisites this causes problems. Instead reuse
1707 a static buffer (resizeable) for each variable.
1709 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1710 target-specific variable definitions. Check for it and set an
1712 (record_target_var): Set the export field to v_export if the
1713 "exported" flag is set.
1714 * doc/make.texi (Target-specific): Document the ability to use
1717 * doc/make.texi: Change the name of the section on automatic
1718 variables from "Automatic" to "Automatic Variables". Added text
1719 clarifying the scope of automatic variables.
1721 2002-10-04 Paul D. Smith <psmith@gnu.org>
1723 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1725 (record_files): Ditto.
1727 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1728 the search for the '=' to only within the enclosing parens.
1730 2002-10-03 Paul D. Smith <psmith@gnu.org>
1732 Version 3.80 released.
1734 * dir.c: Change hash functions to use K&R function definition style.
1735 * function.c: Ditto.
1737 * variable.c: Ditto.
1739 Update to automake 1.7.
1741 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1742 (pdf): Remove this target as automake now provides one.
1744 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1746 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1748 * makefile.com: Updates for GNU make 3.80.
1749 * makefile.vms: Ditto.
1751 2002-09-23 Paul D. Smith <psmith@gnu.org>
1753 * read.c (enum make_word_type): Remove w_comment.
1754 (get_next_mword): Don't treat comment characters as special; where
1755 this function is used we will never see a comment (it's stripped
1756 before we get here) and treating comments specially means that
1757 targets like "foo\#bar" aren't handled properly.
1759 2002-09-18 Paul D. Smith <psmith@gnu.org>
1761 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1763 * read.c (eval): Expansion of arguments to export/unexport was
1764 ignoring all arguments after the first one. Change the algorithm
1765 to expand the whole line once, then parse the results.
1767 2002-09-17 Paul D. Smith <psmith@gnu.org>
1769 Fix Bug #940 (plus another bug I found while looking at this):
1771 * read.c (record_target_var): enter_file() will add a new entry if
1772 it's a double-colon target: we don't want to do that in this
1773 situation. Invoke lookup_file() and only enter_file() if it does
1774 not already exist. If the file we get back is a double-colon then
1775 add this variable to the "root" double-colon target.
1777 * variable.c (initialize_file_variables): If this file is a
1778 double-colon target but is not the "root" target, then initialize
1779 the root and make the root's variable list the parent of our
1782 2002-09-13 Paul D. Smith <psmith@gnu.org>
1784 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1786 * hash.c (round_up_2): Get rid of a warning.
1788 2002-09-12 Paul D. Smith <psmith@gnu.org>
1790 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1791 so it doesn't complain about getloadavg.c.
1793 * commands.c (set_file_variables): Make sure we always alloca() at
1794 least 1 character for the value of $? (for '\0').
1796 2002-09-11 Paul D. Smith <psmith@gnu.org>
1798 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1799 macro to use RESULT instead of the incorrect _RESULT_.
1801 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1802 and atomic_readdir(). We need to #include dirent.h to get this to
1804 * misc.c (atomic_readdir): Fix typos.
1806 2002-09-10 Paul D. Smith <psmith@gnu.org>
1808 * read.c (eval): Expand variable lists given to export and
1809 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1810 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1812 * doc/make.texi (Variables/Recursion): Document this.
1813 (Conditional Syntax): And here.
1815 2002-09-09 Paul D. Smith <psmith@gnu.org>
1817 * configure.in: Check for memmove().
1819 2002-09-07 Paul D. Smith <psmith@gnu.org>
1821 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1822 Michael Sterrett <msterret@coat.com> reports that while it has
1823 SA_RESTART, it does not work properly.
1825 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1826 that invokes stat() and loops to do it again if it returns EINTR.
1827 (atomic_readdir): Ditto, with readdir().
1829 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1830 and readdir() to atomic_stat() and atomic_readdir().
1832 2002-09-04 Paul D. Smith <psmith@gnu.org>
1834 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
1835 reports that GNU make sometimes doesn't recognize that targets can
1836 be made, when directories can be created as prerequisites. He
1837 reports that changing the order of predicates in the DEP->changed
1838 flag test so that lookup_file() is always performed, solves this
1841 2002-08-08 Paul D. Smith <psmith@gnu.org>
1843 * configure.in: Require a newer version of gettext.
1845 * misc.c (perror_with_name): Translate the format string (for
1846 right-to-left language support).
1847 (pfatal_with_name): Ditto.
1849 * main.c: Create a static array of strings to store the usage
1850 text. This is done to facilitate translations.
1851 (struct command_switch): Remove argdesc and description fields.
1852 (switches): Remove values for obsolete fields.
1853 (print_usage): Print each element of the usage array.
1855 * hash.c: Change function definitions to be K&R style.
1857 2002-08-02 Paul D. Smith <psmith@gnu.org>
1859 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
1860 this one because it's too hard to get right. We'll look at it for
1862 * main.c (main): Don't create the .TARGETS variable.
1863 * variable.c (handle_special_var): Don't handle .TARGETS.
1865 2002-08-01 Paul D. Smith <psmith@gnu.org>
1867 * main.c (switches): Add a new option, -B (--always-make). If
1868 specified, make will rebuild all targets that it encounters even
1869 if they don't appear to be out of date.
1870 (always_make_flag): New flag.
1871 * make.h: Extern always_make_flag.
1872 * remake.c (update_file_1): Check always_make_flag; if it's set we
1873 will always rebuild any target we can, even if none of its
1874 prerequisites are newer.
1877 * doc/make.texi (Shell Function): Make it clear that make
1878 variables marked as "export" are not passed to instances of the
1881 Add new introspection variable .VARIABLES and .TARGETS.
1883 * variable.c (handle_special_var): New function. If the variable
1884 reference passed in is "special" (.VARIABLES or .TARGETS),
1885 calculate the new value if necessary. .VARIABLES is handled here:
1886 walk through the hash of defined variables and construct a value
1887 which is a list of the names. .TARGETS is handled by
1888 build_target_list().
1889 (lookup_variable): Invoke handle_special_var().
1890 * file.c (build_target_list): Walk through the hask of known files
1891 and construct a list of the names of all the ones marked as
1893 * main.c (main): Initialize them to empty (and as simple variables).
1894 * doc/make.texi (Special Variables): Document them.
1895 * NEWS: Mention them.
1897 * variable.h (struct variable): Add a new flag "exportable" which
1898 is true if the variable name is valid for export.
1899 * variable.c (define_variable_in_set): Set "exportable" when a new
1900 variable is defined.
1901 (target_environment): Use the "exportable" flag instead of
1902 re-checking the name here... an efficiency improvement.
1904 2002-07-31 Paul D. Smith <psmith@gnu.org>
1906 * config.h-vms.template: Updates to build on VMS. Thanks to
1907 Brian_Benning@aksteel.com for helping verify the build.
1908 * makefile.com: Build the new hash.c file.
1909 * hash.h: Use strcpmi(), not stricmp(), in the
1910 HAVE_CASE_INSENSITIVE_FS case.
1912 2002-07-30 Paul D. Smith <psmith@gnu.org>
1914 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
1915 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
1916 Reported by <Brian_Benning@aksteel.com>.
1918 2002-07-10 Paul D. Smith <psmith@gnu.org>
1920 * variable.c (pop_variable_scope): Remove variable made unused by
1921 new hash infrastructure.
1922 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
1923 comparisons as well as name comparisons.
1924 * variable.h: Add a prototype for new hash_init_function_table().
1925 * file.c (lookup_file): Remove variables made unused by new hash
1927 * dir.c (directory_contents_hash_2): Missing return of hash value.
1928 (dir_contents_file_exists_p): Remove variables made unused by new
1929 hash infrastructure.
1932 Installed Greg McGary's integration of the hash functions from the
1933 GNU id-utils package:
1935 2002-07-10 Greg McGary <greg@mcgary.org>
1937 * scripts/functions/filter-out: Add literals to to the
1938 pattern space in order to add complexity, and trigger
1939 use of an internal hash table. Fix documentation strings.
1940 * scripts/targets/INTERMEDIATE: Reverse order of files
1941 passed to expected `rm' command.
1943 2002-07-10 Greg McGary <greg@mcgary.org>

2035 2002-07-10 Paul D. Smith <psmith@gnu.org>
2037 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2038 prerequisite list. A real SysV make will expand the entire
2039 prerequisites list _twice_: we don't do that as it's a big
2040 backward-compatibility problem. We only replace those specific
2043 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2044 references left in the list of prerequisites. Check for .POSIX as
2045 we record targets, so we can disable non-POSIX behavior while
2046 reading makefiles as well as running them.
2047 (eval): Check the prerequisite list to see if we have anything
2048 that looks like a SysV prerequisite variable reference.
2050 2002-07-09 Paul D. Smith <psmith@gnu.org>
2052 * doc/make.texi (Prerequisite Types): Add a new section describing
2053 order-only prerequisites.
2055 * read.c (uniquize_deps): If we have the same file as both a
2056 normal and order-only prereq, get rid of the order-only prereq,
2057 since the normal one supersedes it.
2059 2002-07-08 Paul D. Smith <psmith@gnu.org>
2061 * AUTHORS: Added Greg McGary to the AUTHORS file.
2062 * NEWS: Blurbed order-only prerequisites.
2063 * file.c (print_file): Show order-only deps properly when printing
2066 * maintMakefile: Add "update" targets for wget'ing the latest
2067 versions of various external files. Taken from Makefile.maint in
2070 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2071 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2073 2002-07-07 Paul D. Smith <psmith@gnu.org>
2075 * po/*.po: Remove. We'll use wget to retrieve them at release
2078 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2079 rather than a shell you get an exception. Make sure we look up
2080 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2082 * remake.c (notice_finished_file): Fix handling of -t flag.
2083 Patch provided by Henning Makholm <henning@makholm.net>.
2085 * implicit.c (pattern_search): Some systems apparently run short
2086 of stack space, and using alloca() in this function caused an
2087 overrun. I modified it to use xmalloc() on the two variables
2088 which seemed like they might get large. Fixes Bug #476.
2090 * main.c (print_version): Update copyright notice to conform with
2092 (print_usage): Update help output.
2094 * function.c (func_eval): Create a new make function, $(eval
2095 ...). Expand the arguments, put them into a buffer, then invoke
2096 eval_buffer() on the resulting string.
2097 (func_quote): Create a new function, $(quote VARNAME). Inserts
2098 the value of the variable VARNAME without expanding it any
2101 * read.c (struct ebuffer): Change the linebuffer structure to an
2102 "eval buffer", which can be either a file or a buffer.
2103 (eval_makefile): Move the code in the old read_makefile() which
2104 located a makefile into here: create a struct ebuffer with that
2105 information. Have it invoke the new function eval() with that
2107 (eval_buffer): Create a new function that creates a struct ebuffer
2108 that holds a string buffer instead of a file. Have it invoke
2109 eval() with that ebuffer.
2110 (eval): New function that contains the guts of the old
2111 read_makefile() function: this function parses makefiles. Obtains
2112 data to parse from the provided ebuffer. Some modifications to
2113 make the flow of the function cleaner and clearer. Still could
2114 use some work here...
2115 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2116 contents of the define/endef variable from the ebuffer.
2117 (readstring): Read the next line from a string-style ebuffer.
2118 (readline): Read the next line from an ebuffer. If it's a string
2119 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2122 * dep.h (eval_buffer): Prototype eval_buffer();
2124 * variable.c (do_variable_definition): Make sure that all
2125 non-target-specific variables are registered in the global set.
2126 If we're invoked from an $(eval ...) we might be inside a $(call
2127 ...) or other function which has pushed a variable scope; we still
2128 want to define our variables from evaluated makefile code in the
2131 2002-07-03 Greg McGary <greg@mcgary.org>
2133 * dep.h (struct dep) [ignore_mtime]: New member.
2134 [changed]: convert to a bitfield.
2135 * implicit.c (pattern_search): Zero ignore_mtime.
2136 * main.c (main, handle_non_switch_argument): Likewise.
2137 * rule.c (convert_suffix_rule): Likewise.
2138 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2139 (read_makefile): Parse '|' in prerequisite list.
2140 (uniquize_deps): Consider ignore_mtime when comparing deps.
2141 * remake.c (update_file_1, check_dep): Don't force remake for
2142 dependencies that have d->ignore_mtime.
2143 * commands.c (FILE_LIST_SEPARATOR): New constant.
2144 (set_file_variables): Don't include a
2145 prerequisite in $+, $^ or $? if d->ignore_mtime.
2148 2002-06-18 Paul D. Smith <psmith@gnu.org>
2150 * make.texinfo: Updates for next revision. New date/rev/etc.
2151 Recreate all Info menus. Change license on the manual to the GNU
2152 Free Documentation License. A number of typos.
2153 (Variables Simplify): Don't use "-" before it's defined.
2154 (Automatic Prerequisites): Rewrite the target example to work
2155 properly if the compile fails. Remove incorrect comments about
2156 how "set -e" behaves.
2157 (Text Functions): Move the "word", "wordlist", "words", and
2158 "firstword" functions here, from "File Name Functions".
2159 * make-stds.texi: Update from latest GNU version.
2160 * fdl.texi: (created) Import the latest GNU version.
2162 2002-06-06 Paul D. Smith <psmith@gnu.org>
2164 * variable.c (do_variable_definition): New function: extract the
2165 part of try_variable_definition() that actually sets the value
2166 into a separate function.
2167 (try_variable_definition): Call do_variable_definition() after
2168 parsing the variable definition string.
2169 (define_variable_in_set): Make the name argument const.
2171 * variable.h (enum variable_flavor): Make public.
2172 (do_variable_definition): Create prototype.
2174 * read.c (read_all_makefiles): Create a new built-in variable,
2176 (read_makefile): Add each makefile read in to this variable value.
2178 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2180 * Makefile.DOS.template: Tweak according to changes in the
2181 distribution. Add back the dependencies of *.o files.
2183 * configh.dos.template: Synchronize with config.h.in.
2185 2002-05-09 Paul D. Smith <psmith@gnu.org>
2187 * file.c (file_timestamp_now): Use K&R function declaration.
2189 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2190 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2191 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2192 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2193 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2194 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2195 nlist.n_name is a pointer rather than an array.
2197 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2198 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2199 * configure.in: Use it instead of the old version.
2201 * main.c (main): Prefer setvbuf() to setlinebuf().
2203 2002-05-08 Paul D. Smith <psmith@gnu.org>
2205 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2206 (loadavg_LDADD): Ditto.
2208 2002-04-29 Paul D. Smith <psmith@gnu.org>
2210 * expand.c (recursively_expand_for_file): Rename
2211 recursively_expand() to recursively_expand_for_file() and provide
2212 an extra argument, struct file. If the argument is provided, set
2213 the variable scope to that of the file before expanding.
2214 * variable.h (recursively_expand): Make this a macro that invokes
2215 recursively_expand_for_file() with a NULL file pointer.
2216 * variable.c (target_environment): Call the renamed function and
2217 provide the current file context.
2218 Fixes Debian bug #144306.
2220 2002-04-28 Paul D. Smith <psmith@gnu.org>
2222 Allow $(call ...) user-defined variables to be self-referencing
2223 without throwing an error. Allows implementation of transitive
2224 closures, among other possibly useful things.
2225 Requested by: Philip Guenther <guenther@sendmail.com>
2227 * variable.h (struct variable): Add a new field: exp_count, and
2228 new macros to hold its size and maximum value.
2229 (warn_undefined): Make this a macro.
2230 * variable.c (define_variable_in_set): Initialize it.
2231 * expand.c (recursively_expand): If we detect recursive expansion
2232 of a variable, check the exp_count field. If it's greater than 0
2233 allow the recursion and decrement the count.
2234 (warn_undefined): Remove this (now a macro in variable.h).
2235 * function.c (func_call): Before we expand the user-defined
2236 function, modify its exp_count field to contain the maximum
2237 number of recursive calls we'll allow. After the call, reset it
2240 2002-04-21 Paul D. Smith <psmith@gnu.org>
2242 Modified to use latest autoconf (2.53), automake (1.6.1), and
2243 gettext (0.11.1). We're using gettext's new "external" support,
2244 to avoid including libintl source with GNU make.
2246 * README.cvs: New file. Explain how to build GNU make from CVS.
2248 * configure.in: Modify checking for the system glob library.
2249 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2250 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2251 etc. will manage it correctly). Set an automake conditional
2252 USE_LOCAL_GLOB to decide whether to compile the glob library.
2254 * getloadavg.c (main): Include make.h in the "TEST" program to
2257 * Makefile.am: Remove special rules for loadavg. Replace them
2258 with Automake capabilities for building extra programs.
2260 * signame.c: This file does nothing if the system provide
2261 strsignal(). If not, it implements strsignal(). If the system
2262 doesn't define sys_siglist, then we make our own; otherwise we use
2264 * signame.h: Removed.
2266 * main.c (main): No need to invoke signame_init(). Update copyright.
2268 * ABOUT-NLS: Removed.
2269 * gettext.c: Removed.
2270 * gettext.h: Get a simplified copy from the gettext package.
2272 * i18n/*.po: Moved to po/.
2275 * config/*: Created. Contains package configuration helper files.
2276 * config.guess, config.sub: Moved to config directory.
2278 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2279 Rework to use new-style autoconf features. Use the "external"
2280 mode for gettext. Make the build.sh config file conditional on
2281 whether build.sh.in exists, to avoid autoconf errors.
2282 * acinclude.m4: Removed almost all macros as being obsolete.
2283 Rewrote remaining macros to use AC_DEFINE.
2284 * acconfig.h: Removed.
2286 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2287 conditional to handle customs support. Remove special handling
2290 2002-04-20 Paul D. Smith <psmith@gnu.org>
2292 * function.c (func_call): Don't mark the argument variables $1,
2293 etc. as recursive. They've already been fully expanded so
2294 there's no need to do it again, and doing so strips escaped $'s.
2295 Reported by Sebastian Glita <glseba@yahoo.com>.
2297 * remake.c (notice_finished_file): Walk through double-colon
2298 entries via the prev field, not the next field!
2299 Reported by Greg McGary <greg@mcgary.org>.
2301 * main.c (main): If the user specifies -q and asks for a specific
2302 target which is a makefile, we got an assert. In that case it
2303 turns out we should continue normally instead.
2305 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2307 * i18n/he.po: Installed a new translation.
2309 2002-01-07 Paul D. Smith <psmith@gnu.org>
2311 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2313 2001-12-04 Paul D. Smith <psmith@gnu.org>
2315 * i18n/ja.po: Installed an updated translation.
2317 2001-09-06 Paul Eggert <eggert@twinsun.com>
2319 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2320 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2322 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2324 (main): Get rid of any avoidable limit on stack size.
2326 2001-09-04 Paul D. Smith <psmith@gnu.org>
2328 * i18n/da.po: Installed an updated translation.
2330 2001-08-03 Paul D. Smith <psmith@gnu.org>
2332 * i18n/fr.po: Installed an updated translation.
2333 Resolves Debian bug #106720.
2335 2001-06-13 Paul D. Smith <psmith@gnu.org>
2337 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2340 2001-06-11 Paul D. Smith <psmith@gnu.org>
2342 * i18n/ko.po: Installed a new translation.
2344 2001-05-06 Paul D. Smith <psmith@gnu.org>
2346 Modify the EINTR handling.
2348 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2349 the way in which we manage the file descriptor/signal handler race
2350 trap to be more efficient.
2352 2001-05-06 Paul Eggert <eggert@twinsun.com>
2354 Restart almost all system calls that are interrupted, instead
2355 of worrying about EINTR. The lone exception is the read() for
2358 * configure.in (HAVE_SA_RESTART): New macro.
2359 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2360 * main.c (main): Use SA_RESTART instead of the old,
2361 nonstandard SA_INTERRUPT.
2363 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2364 * main.c (bsd_signal): New function or macro,
2365 if the implementation doesn't supply it.
2366 (The bsd_signal function will be in POSIX 1003.1-200x.)
2367 (HANDLESIG): Remove.
2368 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2370 * make.h (EINTR_SET): Remove.
2371 (SA_RESTART): New macro.
2373 * arscan.c (ar_member_touch): Don't worry about EINTR.
2374 * function.c (func_shell): Likewise.
2375 * job.c (reap_children, free_child, new_job): Likewise.
2376 * main.c (main): Likewise.
2377 * remake.c (touch_file, name_mtime): Likewise.
2379 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2380 if fstat failed with errno!=EINTR, the error was ignored.
2382 * job.c (set_child_handler_action_flags): New function.
2383 (new_job): Use it to temporarily clear the SIGCHLD action flags
2384 while reading the token.
2386 2001-05-02 Paul D. Smith <psmith@gnu.org>
2388 * job.c (start_job_command): Don't add define/endef per-line flags
2389 to the top-level flags setting.
2391 2001-04-03 Paul D. Smith <psmith@gnu.org>
2393 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2394 bit on error, so check for odd return values, not non-0 return
2396 (VMS_get_member_info): Calculate the timezone differences correctly.
2397 Reported by John Fowler <jfowler@nyx.net>.
2400 2001-03-14 Paul D. Smith <psmith@gnu.org>
2402 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2403 value before invoking define_variable().
2404 Reported by John Fowler <jfowler@nyx.net>.
2406 2001-02-07 Paul D. Smith <psmith@gnu.org>
2408 * read.c (record_target_var): If we reset the variable due to a
2409 command-line variable setting overriding it, turn off the "append"
2412 2001-01-17 Paul D. Smith <psmith@gnu.org>
2414 * variable.c (lookup_variable) [VMS]: When getting values from the
2415 environment, allocate enough space for the _value_ plus escapes,
2416 not enough space for the name plus escapes :-/.
2417 Reported by John Fowler <jfowler@nyx.net>.
2419 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2420 warnings that make generates, so it doesn't look like an error.
2421 Reported by Karl Berry <karl@gnu.org>.
2424 Fix for PR/2020: Rework appended target-specific variables. I'm
2425 fairly confident this algorithm is finally correct.
2427 * expand.c (allocated_variable_append): Rewrite. Instead of
2428 expanding each appended variable then adding all the expanded
2429 strings together, we append all the unexpanded values going up
2430 through the variable set contexts, then expand the final result.
2431 This behaves just like non-target-specific appended variable
2432 values, while the old way didn't in various corner cases.
2433 (variable_append): New function: recursively append the unexpanded
2434 value of a variable, walking from the outermost variable scope to
2436 * variable.c (lookup_variable): Remove the code that looked up the
2437 variable set list if the found variable was "append". We don't
2439 (lookup_variable_in_set): Make this non-static so we can use it
2441 (try_variable_definition): Use lookup_variable_in_set() rather
2442 than faking out current_variable_set_list by hand (cleanup).
2443 * variable.h: Add a prototype for the now non-static
2444 lookup_variable_in_set().
2446 2000-11-17 Paul D. Smith <psmith@gnu.org>
2448 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2449 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2450 before throwing a fit.
2452 2000-11-17 Paul D. Smith <psmith@gnu.org>
2454 * read.c (readline): CRLF calculations had a hole, if you hit the
2455 buffer grow scenario just right. Reworked the algorithm to avoid
2456 the need for len or lastlen at all. Problem description with
2457 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2459 2000-10-24 Paul D. Smith <psmith@gnu.org>
2461 * gettext.c (SWAP): Declare this with the prototype, otherwise
2462 some systems don't work (non-32-bit? Reported for Cray T3E).
2463 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2465 2000-10-05 Paul D. Smith <psmith@gnu.org>
2467 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2468 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2470 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2472 2000-09-22 Paul D. Smith <psmith@gnu.org>
2474 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2475 parts of the real gettext.h here, and we expect to really include
2476 the real gettext.h later. If we keep this #define, it's ignored.
2478 2000-09-21 Paul D. Smith <psmith@gnu.org>
2480 * main.c (log_working_directory): Rework the text to use complete
2481 sentences, to make life simpler for the translators.
2483 2000-08-29 Paul D. Smith <psmith@gnu.org>
2485 * file.c (remove_intermediates): Print a debug message before we
2486 remove intermediate files, so the user (if she uses -d) knows
2489 2000-08-21 Paul D. Smith <psmith@gnu.org>
2491 * variable.c (try_variable_definition): Change how we handle
2492 target-specific append variable defns: instead of just setting the
2493 value, expand it as an append _but_ only within the current
2494 target's context. Otherwise we lose all but the last value if the
2495 variable is appended more than once within the current target
2496 context. Fixes PR/1831.
2498 2000-08-16 Paul D. Smith <psmith@gnu.org>
2500 * function.c (func_shell): Nul-terminate the buffer before
2501 printing an exec error message (just in case it's not!).
2502 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2504 2000-07-25 Paul D. Smith <psmith@gnu.org>
2506 * job.c (construct_command_argv_internal): Add "~" to the list of
2507 sh_chars[] which disallow optimizing out the shell call.
2509 2000-07-23 Paul Eggert <eggert@twinsun.com>
2511 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2512 supersedes --disable-nsec-timestamps.
2513 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2514 * README: Remove --disable-nsec-timestamps.
2516 * filedef.h (struct file.low_resolution_time): New member.
2517 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2518 * remake.c (update_file_1):
2519 Avoid spurious rebuilds due to low resolution time stamps,
2520 generalizing the earlier code that applied only to archive members.
2521 (f_mtime): Archive members always have low resolution time stamps.
2523 * configure.in: Remove --disable-nsec-timestamps, as this has
2524 been superseded by .LOW_RESOLUTION_TIME.
2526 2000-07-23 Paul Eggert <eggert@twinsun.com>
2528 * configure.in (enable_nsec_timestamps): Renamed from
2529 make_cv_nsec_timestamps, since enable/disable options
2530 shouldn't be cached.
2532 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2533 and Paul Eggert <eggert@twinsun.com>
2535 * file.c (file_timestamp_now):
2536 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2537 so that clock_gettime is not linked unless needed.
2539 * filedef.h (FILE_TIMESTAMP_HI_RES):
2540 Remove definition; "configure" now does this.
2542 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2543 to before high resolution file timestamp check,
2544 since that check now uses uintmax_t.
2545 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2546 high resolution file timestamps.
2547 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2548 so that we don't link in clock_gettime unnecessarily.
2550 2000-07-17 Paul D. Smith <psmith@gnu.org>
2552 * i18n/ja.po: New version of the translation file.
2554 2000-07-07 Paul D. Smith <psmith@gnu.org>
2556 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2557 the offset calculation.
2558 (name_mtime): Replace EINTR test with EINTR_SET macro.
2560 2000-07-07 Paul Eggert <eggert@twinsun.com>
2564 * remake.c (update_file_1):
2565 Avoid spurious rebuilds of archive members due to their
2566 timestamp resolution being only one second.
2567 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2568 the clock's resolution being lower than file timestamps'.
2569 When warning about future timestamps, report only the discrepancy,
2570 not the absolute value of the timestamp and the current time.
2572 * file.c (file_timestamp_now): New arg RESOLUTION.
2573 * filedef.h (file_timestamp_now): Likewise.
2574 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2576 2000-07-05 Paul D. Smith <psmith@gnu.org>
2578 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2579 to listp. Fixes PR/1793.
2581 2000-06-26 Paul Eggert <eggert@twinsun.com>
2583 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2585 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2587 * remake.c (f_mtime): Remove unused var memtime.
2589 2000-06-25 Martin Buchholz <martin@xemacs.org>
2591 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2592 Ran spell-check on make.texinfo.
2594 2000-06-23 Paul D. Smith <psmith@gnu.org>
2596 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2597 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2598 * make.h: Define these macros.
2600 * Version 3.79.1 released.
2602 * configure.in: Add a new option, --disable-nsec-timestamps, to
2603 avoid using sub-second timestamps on systems that support it. It
2604 can lead to problems, e.g. if your makefile relies on "cp -p".
2605 * README.template: Document the issue with "cp -p".
2607 * config.guess, config.sub: Updated.
