28 2006-04-06 Paul D. Smith <psmith@gnu.org>
30 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
31 require an ISO C 1989 standard compiler and runtime library.
33 * Makefile.am: Remove the ansi2knr feature.
35 * make.h: Remove the PARAMS() macro definition and all uses of it.

59 support from automake, as described in the Texinfo manual.
61 2006-03-25 Eli Zaretskii <eliz@gnu.org>
63 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
64 with lastslash, since the latter points to filename, not to
66 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
67 Declare and define sh_chars_sh[].
69 2006-03-23 Paul D. Smith <psmith@gnu.org>
71 * configure.in: Look for build.sh.in in $srcdir so it will be
72 built for remote configurations as well.
74 * Makefile.am: Make sure to clean up build.sh during distclean.
75 Fixes Savannah bug #16166.
77 * misc.c (log_access): Takes a const char *.
78 * function.c (fold_newlines): Takes an unsigned int *.
79 Both fixes for Savannah bug #16170.
81 2006-03-22 Boris Kolpackov <boris@kolpackov.net>

93 make sure I don't forget any).
95 * main.c (clean_jobserver): Move jobserver cleanup code into a new
97 (die): Cleanup code was removed from here; call the new function.
98 (main): If we are re-execing, clean up the jobserver first so we
99 don't leak file descriptors.
100 Fix bug reported by Craig Fithian <craig.fithian@citigroup.com>.
102 2006-03-17 Paul D. Smith <psmith@gnu.org>
104 * maintMakefile (do-po-update): Rewrite this rule to clean up and

106 Patch from Joseph Myers <joseph@codesourcery.com>
108 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
110 * dep.h (struct dep): Add the stem field.
111 * misc.c (alloc_dep, free_dep): New functions.
112 (copy_dep_chain): Copy stem.
113 (free_dep_chain): Use free_dep.
114 * read.c (record_files): Store stem in the dependency line.
115 * file.c (expand_deps): Use stem stored in the dependency line. Use
116 free_dep_chain instead of free_ns_chain.

123 2006-03-14 Paul D. Smith <psmith@gnu.org>
125 * expand.c (variable_append): Instead of appending everything then
126 expanding the result, we expand (or not, if it's simple) each part
128 (allocated_variable_append): Don't expand the final result.
129 Fixes Savannah bug #15913.
131 2006-03-09 Paul Smith <psmith@gnu.org>
133 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
134 listed non-existent files as changed. Turns out there's a bug in
135 the Linux kernel builds which means that this change causes
136 everything to rebuild every time. We will re-introduce this fix
137 in the next release, to give them time to fix their build system.
138 Fixes Savannah bug #16002.
139 Introduces Savannah bug #16051.
141 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
142 we *don't* find UNIX "/".
143 Reported by David Ergo <david.ergo@alterface.com>

154 to be null; don't core in that case.
156 2006-02-19 Paul D. Smith <psmith@gnu.org>
158 * commands.c (set_file_variables): Realloc, not malloc, the static
159 string values to avoid memory leaks.
161 * expand.c (recursively_expand_for_file): Only set reading_file to
162 an initialized value.
164 * implicit.c (pattern_search): We need to make a copy of the stem
165 if we get it from an intermediate dep, since those get freed.
167 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
169 (enter_file) [VMS]: Ditto.
170 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
172 2006-02-24 Eli Zaretskii <eliz@gnu.org>

176 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
177 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
178 the calls to _beginthreadex.
180 * expand.c (recursively_expand_for_file): Initialize `save' to
181 prevent compiler warnings.
183 2006-02-18 Eli Zaretskii <eliz@gnu.org>
185 * job.c (construct_command_argv_internal): Don't create a temporary
186 script/batch file if we are under -n. Call _setmode to switch the
187 script file stream to text mode.
189 2006-02-17 Paul D. Smith <psmith@gnu.org>
191 * variable.c (merge_variable_set_lists): Don't try to merge the
192 global_setlist. Not only is this useless, but it can lead to
193 circularities in the linked list, if global_setlist->next in one
194 list gets set to point to another list which also ends in
196 Fixes Savannah bug #15757.
198 2006-02-15 Paul D. Smith <psmith@gnu.org>
200 Fix for Savannah bug #106.
202 * expand.c (expanding_var): Keep track of which variable we're
203 expanding. If no variable is being expanded, it's the same as
205 * make.h (expanding_var): Declare it.
206 * expand.c (recursively_expand_for_file): Set expanding_var to the
207 current variable we're expanding, unless there's no file info in
208 it (could happen if it comes from the command line or a default
209 variable). Restore it before we exit.
210 * expand.c (variable_expand_string): Use the expanding_var file
211 info instead of the reading_file info.
212 * function.c (check_numeric): Ditto.
214 (func_wordlist): Ditto.

217 (handle_function): Ditto.
219 2006-02-14 Paul D. Smith <psmith@gnu.org>
221 * read.c (eval): Even if the included filenames expands to the
222 empty string we still need to free the allocated buffer.
224 * implicit.c (pattern_search): If we allocated a variable set for
225 an impossible file, free it.
226 * variable.c (free_variable_set): New function.
227 * variable.h: Declare it.
229 * read.c (read_all_makefiles): Makefile names are kept in the
230 strcache, so there's never any need to alloc/free them.
233 * main.c (main): Add "archives" to the .FEATURES variable if
234 archive support is enabled.
235 * doc/make.texi (Special Variables): Document it.
237 2006-02-13 Paul D. Smith <psmith@gnu.org>
239 * implicit.c (pattern_search): Add checking for DOS pathnames to
240 the pattern rule target LASTSLASH manipulation.
241 Fixes Savannah bug #11183.
243 2006-02-11 Paul D. Smith <psmith@gnu.org>
245 * (ALL FILES): Updated copyright and license notices.
247 2006-02-10 Paul D. Smith <psmith@gnu.org>
249 A new internal capability: the string cache is a read-only cache
250 of strings, with a hash table interface for fast lookup. Nothing
251 in the cache will ever be freed, so there's no need for reference
252 counting, etc. This is the beginning of a full solution for
253 Savannah bug #15182, but for now we only store makefile names here.
255 * strcache.c: New file. Implement a read-only string cache.
256 * make.h: Add prototypes for new functions.
257 * main.c (initialize_global_hash_tables): Initialize the string cache.
258 (print_data_base): Print string cache stats.
259 * read.c (eval_makefile): Use the string cache to store makefile
260 names. Rewrite the string allocation to be sure we free everything.
262 2006-02-10 Eli Zaretskii <eliz@gnu.org>
264 * dir.c (dir_contents_file_exists_p): Don't opendir if the
265 directory time stamp didn't change, except on FAT filesystems.
266 Suggested by J. David Bryan <jdbryan@acm.org>.
268 2006-02-09 Paul D. Smith <psmith@gnu.org>
270 * function.c (func_or): Implement a short-circuiting OR function.
271 (func_and): Implement a short-circuiting AND function.
272 (function_table_init): Update the table with the new functions.
273 * doc/make.texi (Conditional Functions): Changed the "if" section
274 to one on general conditional functions. Added documentation for
275 $(and ...) and $(or ...) functions.
276 * NEWS: Note new $(and ...) and $(or ...) functions.
278 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
280 * job.h (struct child): Add the dontcare bitfield.
281 * job.c (new_job): Cache dontcare flag.
282 * job.c (reap_children): Use cached dontcare flag instead of the
283 one in struct file. Fixes Savannah bug #15641.
285 2006-02-06 Paul D. Smith <psmith@gnu.org>
287 * vpath.c (selective_vpath_search): If the file we find has a
288 timestamp from -o or -W, use that instead of the real time.
289 * remake.c (f_mtime): If the mtime is a special token from -o or
290 -W, don't overwrite it with the real mtime.
291 Fixes Savannah bug #15341.
293 Updates from Markus Mauhart <qwe123@chello.at>:
295 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

297 invalid handle values.
298 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
299 manage invalid handles; remove them.
300 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
301 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
302 * README.cvs: Updates for building from CVS.
304 2006-02-05 Paul D. Smith <psmith@gnu.org>
306 * file.c (enter_file): Keep track of the last double_colon entry,
307 to avoid walking the list every time we want to add a new one.
308 Fixes Savannah bug #15533.
309 * filedef.h (struct file): Add a new LAST pointer.
311 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
312 the comparison. For 64-bits systems the result of the subtraction
313 might not fit into an int. Use comparison instead.
314 Fixes Savannah bug #15534.
316 * doc/make.texi: Update the chapter on writing commands to reflect
317 the changes made in 3.81 for backslash/newline and SHELL handling.

335 * prepare_w32.bat: Remove this file from the distribution.
337 2006-01-21 Eli Zaretskii <eliz@gnu.org>
339 * remake.c (update_goal_chain): Set g->changed instead of
340 incrementing it, as it is only 8-bit wide, and could overflow if
341 many commands got started in update_file.
343 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
345 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

354 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
355 are already more children than sub_proc.c can handle, behave as if
356 the load were too high.
357 (start_job_command): Fix a typo in error message when process_easy
360 2006-01-14 Eli Zaretskii <eliz@gnu.org>
362 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
363 the shell is not sh.exe.
365 * job.c (create_batch_file): Renamed from create_batch_filename;
366 all callers changed. Don't close the temporary file; return its
367 file descriptor instead. New arg FD allows to return the file
369 (construct_command_argv_internal): Use _fdopen instead of fopen to
372 2006-01-04 Paul D. Smith <psmith@gnu.org>
374 * readme.vms: Updates for case-insensitive VMS file systems from
375 Hartmut Becker <Hartmut.Becker@hp.com>.

386 * remake.c (update_file_1): Mark a prerequisite changed if it
389 * read.c (eval): Be sure to strip off trailing whitespace from the
390 prerequisites list properly. Also, initialize all fields in
391 struct dep when creating a new one.
393 2005-12-28 Paul D. Smith <psmith@gnu.org>
395 * config.h.W32.template [WINDOWS32]: Add in some pragmas to

401 * doc/make.texi (Execution): Add a footnote about changes in
402 handling of backslash-newline sequences. Mention the differences
403 on MS-DOS and MS-Windows.
405 * NEWS: More details about building the MinGW port and a pointer
406 to README.W32. Fix the section name that describes the new
407 backward-incompatible processing of backslash-newline sequences.
408 The special processing of SHELL set to "cmd" is only relevant to
409 MS-Windows, not MS-DOS.
411 2005-12-17 Eli Zaretskii <eliz@gnu.org>
413 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
414 to DWORD, to avoid compiler warnings.
415 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
416 use %ld in format, to avoid compiler warnings.

424 (Environment): Fix punctuation.
425 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
426 (Shell Function, Target-specific): Add @: after "vs."
428 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
430 * read.c (record_target_var): Initialize variable's export field
431 with v_default instead of leaving it "initialized" by whatever
432 garbage happened to be on the heap.
434 2005-12-12 Paul D. Smith <psmith@gnu.org>
436 * make.1: Fix some display errors and document all existing options.
437 Patch provided by Mike Frysinger <vapier@gentoo.org>.
439 2005-12-11 Paul D. Smith <psmith@gnu.org>
441 * implicit.c (pattern_search): If 2nd expansion is not set for
442 this implicit rule, replace the pattern with the stem directly,
443 and don't re-expand the variable list. Along with the other
444 .SECONDEXPANSION changes below, fixes bug #13781.
446 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
448 * implicit.c (pattern_search): Mark other files that this rule
449 builds as targets so that they are not treated as intermediates

454 * remake.c (notice_finished_file): Propagate the change of
455 modification time to all the double-colon entries only if

474 * read.c (record_files): Don't set deps flags if there are no deps.
475 * maintMakefile: We only need to build the templates when we are
476 creating a distribution, so don't do it for "all".
478 2005-10-24 Paul D. Smith <psmith@gnu.org>
480 Make secondary expansion optional: its enabled by declaring the
481 special target .SECONDEXPANSION.
483 * NEWS: Update information on second expansion capabilities.
484 * doc/make.texi (Secondary Expansion): Document the
485 .SECONDEXPANSION special target and its behavior.

489 * file.c (parse_prereqs): New function: break out some complexity
491 (expand_deps): If we aren't doing second expansion, replace % with
492 the stem for static pattern rules. Call the new function.
493 * filedef.h (parse_prereqs): Declare a prototype.
494 * implicit.c (pattern_search): Initialize the new staticpattern
496 * main.c (second_expansion): Declare a global variable to remember

500 * misc.c (free_dep_chain): New function: frees a struct dep list.
501 * read.c (read_all_makefiles): Initialize the staticpattern field.

504 second_expansion global if it's found.
505 Use the new free_dep_chain() instead of doing it by hand.
506 Set the staticpattern field for prereqs of static pattern targets.
508 2005-10-16 Paul D. Smith <psmith@gnu.org>
510 * main.c (main): Set CURDIR to be a file variable instead of a
511 default, so that values of CURDIR inherited from the environment
512 won't override the make value.
514 2005-09-26 Paul D. Smith <psmith@gnu.org>
516 * job.c (construct_command_argv_internal): If the line is empty
517 remember to free the temporary argv strings.
520 2005-09-16 Paul D. Smith <psmith@gnu.org>

524 Reported by Mark Eichin <eichin@metacarta.com>
526 2005-08-29 Paul D. Smith <psmith@gnu.org>
528 * function.c (func_error): On Windows, output from $(info ...)
529 seems to come in the wrong order. Try to force it with fflush().
531 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
533 * read.c (record_files): Move code that sets stem for static
534 pattern rules out of the if (!two_colon) condition so it is
535 also executed for two-colon rules. Fixes Savannah bug #13881.
537 2005-08-08 Paul D. Smith <psmith@gnu.org>
539 * make.h: Don't test that __STDC__ is non-0. Some compilers
540 (Windows for example) set it to 0 to denote "ISO C + extensions".
543 2005-08-07 Paul D. Smith <psmith@gnu.org>
545 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
546 conditional (slightly different version of a fix from Eli).
548 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
549 If make is running in parallel without -k and two jobs die in a
550 row, but not too close to each other, then make will quit without
551 waiting for the rest of the jobs to die.
553 * main.c (die): Don't reset err before calling reap_children() the
554 second time: we still want it to be in the error condition.
555 * job.c (reap_children): Use a static variable, rather than err,
556 to control whether or not the error message should be printed.
558 2005-08-06 Eli Zaretskii <eliz@gnu.org>
560 * w32/subproc/sub_proc.c: Include signal.h.
561 (process_pipe_io, process_file_io): Pass a pointer to a local
562 DWORD variable to GetExitCodeProcess. If the exit code is
563 CONTROL_C_EXIT, put SIGINT into pproc->signal.
565 * job.c [WINDOWS32]: Include windows.h.
566 (main_thread) [WINDOWS32]: New global variable.
567 (reap_children) [WINDOWS32]: Get the handle for the main thread
568 and store it in main_thread.
570 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
571 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
572 doing anything else. When we are done, close the main thread
573 handle and exit with status 130.
575 2005-07-30 Eli Zaretskii <eliz@gnu.org>
577 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
580 * main.c (find_and_set_default_shell): If found a DOSish shell,
581 set sh_found and the value of default_shell, and report the
582 findings in debug mode.
584 * job.c (construct_command_argv_internal): Check unixy_shell, not
585 no_default_sh_exe, to decide whether to use Unixy or DOSish
588 * README.W32: Update with info about the MinGW build.
590 * build_w32.bat: Support MinGW.
592 * w32/subproc/build.bat: Likewise.
594 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
597 * function.c (windows32_openpipe): Fix format strings for printing
600 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
602 (start_job_command): Fix format string for printing the result of
604 (start_job_command) [WINDOWS32]: Do not define.
605 (exec_command): Fix format string for printing HANDLE args.
607 * main.c (handle_runtime_exceptions): Fix sprintf format strings
608 to avoid compiler warnings.
609 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
610 (Note: some of these fixes were submitted independently by J. Grant)
612 2005-07-30 J. Grant <jg@jguk.org>
614 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
615 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
616 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
618 2005-07-15 Paul Smith <psmith@gnu.org>
620 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
621 we don't have a POSIX shell, then revert to the old
622 backslash-newline behavior (where they are stripped).
625 2005-07-08 Paul D. Smith <psmith@gnu.org>
627 * config.h.W32.template: Reorder to match the standard config.h,
628 for easier comparisons.
629 From J. Grant <jg@jguk.org>
631 * maintMakefile: Remove .dep_segment before overwriting it, in
632 case it's not writable or noclobber is set.
633 * expand.c (variable_expand_string): Cast result of pointer
634 arithmetic to avoid a warning.
635 * main.c (switches): Add full-fledged final initializer.
637 2005-07-06 Paul D. Smith <psmith@gnu.org>
639 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
640 * signame.c (strsignal): If we found _sys_siglist[] or
641 __sys_siglist[] use those instead of sys_siglist[].
642 From Albert Chin <china@thewrittenword.com>
644 2005-07-04 Paul D. Smith <psmith@gnu.org>
646 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
647 globfree(); set up to use the GNU versions.
648 From Martin Zinser <zinser@zinser.no-ip.info>
650 2005-07-03 Paul D. Smith <psmith@gnu.org>
652 From J. Grant <jg@jguk.org>:
654 * README.W32.template: Update the Windows and tested MSVC versions.
655 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
656 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
657 * build_w32.bat: Ditto.
658 * w32/subproc/build.bat: Ditto.
660 2005-06-28 Paul D. Smith <psmith@gnu.org>
662 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
663 declaration was checked but not present.
665 2005-06-27 Paul D. Smith <psmith@gnu.org>
667 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
668 to unsigned long. Fixes Savannah bug #13550.
670 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
671 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
672 Fixes Savannah bug #13551.
674 2005-06-26 Paul D. Smith <psmith@gnu.org>
676 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
677 it if ANSI_STRING is not set.
679 2005-06-25 Paul D. Smith <psmith@gnu.org>
681 * read.c (eval): If no filenames are passed to any of the
682 "include" variants, don't print an error.
683 * doc/make.texi (Include): Document this.
684 Fixes Savannah bug #1761.
686 * job.c (construct_command_argv_internal): Sanitize handling of
687 backslash/newline pairs according to POSIX: that is, keep the
688 backslash-newline in the command script, but remove a following
689 TAB character, if present. In the fast path, make sure that the
690 behavior matches what the shell would do both inside and outside
691 of quotes. In the slow path, quote the backslash and put a
692 literal newline in the string.
693 Fixes Savannah bug #1332.
694 * doc/make.texi (Execution): Document the new behavior and give
696 * NEWS: Make a note of the new behavior.
698 * make.h [WINDOWS32]: #include <direct.h>.
699 Fixes Savannah bug #13478.
701 * remake.c (name_mtime): If the stat() of a file fails and the -L
702 option was given and the file is a symlink, take the best mtime of
703 the symlink we can get as the mtime of the file and don't fail.
704 Fixes Savannah bug #13280.
706 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
707 If it's set, then don't stop on STOPCHARs or BLANKs if they're
708 inside a variable reference. Make this function static as it's
710 (eval): Call find_char_unquote() with IGNOREVARS set when we're
711 parsing an unexpanded line looking for semicolons.
712 Fixes Savannah bug #1454.
713 * misc.c (remove_comments): Move this to read.c and make it static
714 as it's only used there. Call find_char_unquote() with new arg.
715 * make.h: Remove prototypes for find_char_unquote() and
716 remove_comments() since they're static now.
718 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
719 its export flag and obtain its value. When we need to re-exec,
720 increment the value and add it into the environment.
721 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
722 * NEWS: Mention MAKE_RESTARTS.
723 * main.c (always_make_set): New variable. Change the -B option to
724 set this one instead.
725 (main): When checking makefiles, only set always_make_flag if
726 always_make_set is set AND the restarts flag is 0. When building
727 normal targets, set it IFF always_make_set is set.
728 (main): Avoid infinite recursion with -W, too: only set what-if
729 files to NEW before we check makefiles if we've never restarted
730 before. If we have restarted, set what-if files to NEW _after_ we
732 Fixes Savannah bug #7566:
734 2005-06-17 Paul D. Smith <psmith@gnu.org>
736 * default.c: Change VMS implicit rules to use $$$$ instead of $$
737 in the prerequisites list.
739 2005-06-12 Paul D. Smith <psmith@gnu.org>
741 Fix Savannah bug # 1328.
743 * configure.in: Check for atexit().
744 * misc.c (close_stdout): Test stdout to see if writes to it have
745 failed. If so, be sure to exit with a non-0 error code. Based on
746 code found in gnulib.
748 * main.c (main): Install close_stdout() with atexit().
750 2005-06-10 Paul D. Smith <psmith@gnu.org>
752 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
754 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
755 headers; make vmsWaitForChildren() static; extern vmsify().
756 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
757 Don't create child_execute_job() here (it's in vmsjobs.c).
758 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
760 2005-06-09 Paul D. Smith <psmith@gnu.org>
762 * variable.c (push_new_variable_scope): File variables point
763 directly to the global_setlist variable. So, inserting a new
764 scope in front of that has no effect on those variables: they
765 don't go through current_variable_set_list. If we're pushing a
766 scope and the current scope is global, push it "the other way" so
767 that the new setlist is in the global_setlist variable, and
768 next points to a new setlist with the global variable set.
769 (pop_variable_scope): Properly undo a push with the new
771 Fixes Savannah bug #11913.
773 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
775 * job.c (reap_children): Don't die of the command failed but
776 the dontcare flag is set. Fixes Savannah bug #13216.
778 * implicit.c (pattern_search): When creating a target from
779 an implicit rule match, lookup pattern target and set precious
780 flag in a newly created target. Fixes Savannah bug #13218.
782 2005-05-13 Paul D. Smith <psmith@gnu.org>
784 Implement "if... else if... endif" syntax.
786 * read.c (eval): Push all checks for conditional words ("ifeq",
787 "else", etc.) down into the conditional_line() function.
788 (conditional_line): Rework to allow "else if..." clause. New
789 return value -2 for lines which are not conditionals. The
790 ignoring flag can now also be 2, which means "already parsed a
791 true branch". If that value is seen no other branch of this
792 conditional can be considered true. In the else parsing if there
793 is extra text after the else, invoke conditional_line()
794 recursively to see if it's another conditional. If not, it's an
795 error. If so, raise the conditional value to this level instead
796 of creating a new conditional nesting level. Special check for
797 "else" and "endif", which aren't allowed on the "else" line.
798 * doc/make.texi (Conditional Syntax): Document the new syntax.
800 2005-05-09 Paul D. Smith <psmith@gnu.org>
802 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
803 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
804 recurses to the w32 directory, even on non-Windows systems. Use
805 the method suggested in the automake manual.
806 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
807 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
809 2005-05-07 Paul D. Smith <psmith@gnu.org>
811 * main.c (die): If we're dying with a fatal error (not that a
812 command has failed), write back any leftover tokens before we go.
814 * job.c (set_child_handler_action_flags): If there are jobs
815 waiting for the load to go down, set an alarm to go off in 1
816 second. This allows us to wake up from a potentially long-lasting
817 read() and start a new job if the load has gone down. Turn it off
819 (job_noop): Dummy signal handler function.
820 (new_job): Invoke it with the new semantics.
822 * docs/make.texi: Document secondary expansion. Various cleanups
825 2005-05-03 Paul D. Smith <psmith@gnu.org>
827 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
828 the targets which are to ultimately be made are called "goals";
829 see the GNU make manual. Also, MAKECMDGOALS, etc.
831 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
832 .DEFAULT_GOAL, and default_target_name to default_goal_name.
833 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
835 2005-05-02 Paul D. Smith <psmith@gnu.org>
837 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
838 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
839 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
840 functions to vmsjobs.c. #include it into jobs.c.
842 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
843 jobserver tokens. I found that this happens when an exported
844 recursive variable contains a $(shell ...) function reference: in
845 this situation we could "forget" to write back a token.
847 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
848 we have. It's not reliable to depend on the number of children in
849 our linked list so keep a separate count.
850 (new_job): Check jobserver_tokens rather than children &&
851 waiting_jobs. Increment jobserver_tokens when we get one.
852 (free_child): If jobserver_tokens is 0, internal error. If it's
853 >1, write a token back to the jobserver pipe (we don't write a
854 token for the "free" job). Decrement jobserver_tokens.
856 * main.c: Add variable master_job_slots.
857 (main): Set it to hold the number of jobs requested if we're the
858 master process, when using the jobserver.
859 (die): Sanity checks: first test jobserver_tokens to make sure
860 this process isn't holding any tokens we didn't write back.
861 Second, if master_job_slots is set count the tokens left in the
862 jobserver pipe and ensure it's the same as master_job_slots (- 1).
864 2005-04-24 Paul D. Smith <psmith@gnu.org>
866 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
867 with -l# can lose jobserver tokens, because waiting jobs are not
868 consulted properly when checking for the "free" token.
870 * job.c (free_child): Count waiting_jobs as having tokens.
871 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
872 handle jobs waiting for the load to drop.
874 2005-04-23 Paul D. Smith <psmith@gnu.org>
876 * main.c (main): Be careful to not core if a variable setting in
877 the environment doesn't contain an '='. This is illegal but can
878 happen in broken setups.
879 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
881 2005-04-12 Paul D. Smith <psmith@gnu.org>
883 The second expansion feature causes significant slowdown. Timing
884 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
885 read the makefile before the feature, to 11+s to do the same
886 operations after the feature. Additionally, memory usage
887 increased drastically. To fix this I added some intelligence that
888 avoids the overhead of the second expansion unless it's required.
890 * dep.h: Add a new boolean field, need_2nd_expansion.
892 * read.c (eval): When creating the struct dep for the target,
893 check if the name contains a "$"; if so set need_2nd_expansion to 1.
894 (record_files): If there's a "%" in a static pattern rule, it gets
895 converted to "$*" so set need_2nd_expansion to 1.
897 * file.c (expand_deps): Rework to be more efficient. Only perform
898 initialize_file_variables(), set_file_variables(), and
899 variable_expand_for_file() if the need_2nd_expansion is set.
901 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
902 (pattern_search): Ditto.
903 * main.c (handle_non_switch_argument): Ditto.
905 * read.c (read_all_makefiles): Ditto.
906 (eval_makefile): Ditto.
908 2005-04-07 Paul D. Smith <psmith@gnu.org>
910 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
911 * variable.c (sync_Path_environment): Ditto.
912 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
914 * main.c (main): Define the .FEATURES variable.
915 * NEWS: Announce .FEATURES.
916 * doc/make.texi (Special Variables): Document .FEATURES.
918 * remake.c (check_dep): If a file is .PHONY, update it even if
919 it's marked intermediate. Fixes Savannah bug #12331.
921 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
923 * file.c (expand_deps): Factor out the second expansion and
924 prerequisite line parsing logic from snap_deps().
926 * file.c (snap_deps): Use expand_deps(). Expand and parse
927 prerequisites of the .SUFFIXES special target first. Fixes
930 2005-03-13 Paul D. Smith <psmith@gnu.org>
932 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
935 2005-03-11 Paul D. Smith <psmith@gnu.org>
937 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
938 available, not undefined (from Earnie Boyd).
940 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
942 * implicit.c (pattern_search): Mark an intermediate target as
943 precious if it happened to be a prerequisite of some (other)
944 target. Fixes Savannah bug #12267.
946 2005-03-09 Paul D. Smith <psmith@gnu.org>
948 * read.c (eval_makefile): Add alloca(0).
949 (eval_buffer): Ditto.
951 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
953 * main.c (main): Use o_file instead of o_default when defining
954 the .DEFAULT_TARGET special variable.
955 * read.c (eval): Use define_variable_global() instead of
956 define_variable() when setting new value for the .DEFAULT_TARGET
957 special variable. Fixes Savannah bug #12266.
959 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
961 * imlicit.c (pattern_search): Mark files for which an implicit
962 rule has been found as targets. Fixes Savannah bug #12202.
964 2005-03-04 Paul D. Smith <psmith@gnu.org>
967 * doc/make.texi (Automatic Variables): Document $|.
969 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
971 * read.c (record_files): Instead of substituting % with
972 actual stem value in dependency list replace it with $*.
973 This fixes stem triple expansion bug.
975 * implicit.c (pattern_search): Copy stem to a separate
976 buffer and make it a properly terminated string. Assign
977 this buffer instead of STEM (which is not terminated) to
978 f->stem. Instead of substituting % with actual stem value
979 in dependency list replace it with $*. This fixes stem
980 triple expansion bug.
982 2005-03-01 Paul D. Smith <psmith@gnu.org>
984 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
985 on Windows, as it takes a handle not a pid. Just exit.
986 Fix from patch #3679, provided by Alessandro Vesely.
988 * configure.in: Update check for sys_siglist[] from autoconf manual.
989 * signame.c (strsignal): Update to use the new autoconf macro.
991 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
993 * read.c (record_files): Add a check for the list of prerequisites
994 of a static pattern rule being empty. Fixes Savannah bug #12180.
996 2005-02-28 Paul D. Smith <psmith@gnu.org>
998 * doc/make.texi (Text Functions): Update docs to allow the end
999 ordinal for $(wordlist ...) to be 0.
1000 * function.c (func_wordlist): Fail if the start ordinal for
1001 $(wordlist ...) is <1. Matches documentation.
1002 Resolves Savannah support request #103195.
1004 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1005 previously we were stopping when !-q, exactly the opposite. This
1006 has been wrong since version 1.34, in 1994!
1007 (update_file): If we got an error don't break out to run more
1008 double-colon rules: just return immediately.
1009 Fixes Savannah bug #7144.
1011 2005-02-27 Paul D. Smith <psmith@gnu.org>
1013 * misc.c (end_of_token): Make argument const.
1014 * make.h: Update prototype.
1016 * function.c (abspath, func_realpath, func_abspath): Use
1017 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1018 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1019 * read.c (record_files): Ditto.
1020 * variable.c (do_variable_definition): Ditto.
1022 * function.c (func_error): Create a new function $(info ...) that
1023 simply prints the message to stdout with no extras.
1024 (function_table_init): Add new function to the table.
1025 * NEWS: Add $(info ...) reference.
1026 * doc/make.texi (Make Control Functions): Document it.
1028 New feature: if the system supports symbolic links, and the user
1029 provides the -L/--check-symlink-time flag, then use the latest
1030 mtime between the symlink(s) and the target file.
1032 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1033 readlink(). If both are available, define MAKE_SYMLINKS.
1034 * main.c: New variable: check_symlink_flag.
1035 (usage): Add a line for -L/--check-symlink-times to the help string.
1036 (switches): Add -L/--check-symlink-times command line argument.
1037 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1038 print a warning and disable it again.
1039 * make.h: Declare check_symlink_flag.
1040 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1041 if the file is a symlink then check each link in the chain and
1042 choose the NEWEST mtime we find as the mtime for the file. The
1043 newest mtime might be the file itself!
1044 * NEWS: Add information about this new feature.
1045 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1047 Avoid core dumps described in Savannah bug # 12124:
1049 * file.c: New variable snapped_deps remember whether we've run
1051 (snap_deps): Set it.
1052 * filedef.h: Extern it.
1053 * read.c (record_files): Check snapped_deps; if it's set then
1054 we're trying to eval a new target/prerequisite relationship from
1055 within a command script, which we don't support. Fatal.
1057 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1059 Implementation of the .DEFAULT_TARGET special variable.
1061 * read.c (eval): If necessary, update default_target_name when
1063 * read.c (record_files): Update default_target_file if
1064 default_target_name has changed.
1065 * main.c (default_target_name): Define.
1066 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1067 default_target_name is set use default_target_file as a root
1069 * filedef.h (default_target_name): Declare.
1070 * dep.h (free_dep_chain):
1071 * misc.c (free_dep_chain): Change to operate on struct nameseq
1072 and change name to free_ns_chain.
1073 * file.c (snap_deps): Update to use free_ns_chain.
1075 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1077 Implementation of the second expansion in explicit rules,
1078 static pattern rules and implicit rules.
1080 * read.c (eval): Refrain from chopping up rule's dependencies.
1081 Store them in a struct dep as a single dependency line. Remove
1082 the code that implements SySV-style automatic variables.
1084 * read.c (record_files): Adjust the code that handles static
1085 pattern rules to expand all percents instead of only the first
1086 one. Reverse the order in which dependencies are stored so that
1087 when the second expansion reverses them again they appear in
1088 the makefile order (with some exceptions, see comments in
1089 the code). Remove the code that implements SySV-style automatic
1092 * file.c (snap_deps): Implement the second expansion and chopping
1093 of dependency lines for explicit rules.
1095 * implicit.c (struct idep): Define an auxiliary data type to hold
1096 implicit rule's dependencies after stem substitution and
1099 * implicit.c (free_idep_chain): Implement.
1101 * implicit.c (get_next_word): Implement helper function for
1102 parsing implicit rule's dependency lines into words taking
1103 into account variable expansion requests. Used in the stem
1106 * implicit.c (pattern_search): Implement the second expansion
1107 for implicit rules. Also fixes bug #12091.
1109 * commands.h (set_file_variables): Declare.
1110 * commands.c (set_file_variables): Remove static specifier.
1112 * dep.h (free_dep_chain): Declare.
1113 * misc.c (free_dep_chain): Implement.
1115 * variable.h (variable_expand_for_file): Declare.
1116 * expand.c (variable_expand_for_file): Remove static specifier.
1118 * make.h (strip_whitespace): Declare.
1119 * function.c (strip_whitespace): Remove static specifier.
1121 2005-02-26 Paul D. Smith <psmith@gnu.org>
1123 * main.c (main): Check for ferror() when reading makefiles from stdin.
1124 Apparently some shells in Windows don't close pipes properly and
1127 2005-02-24 Jonathan Grant <jg@jguk.org>
1129 * configure.in: Add MinGW configuration options, and extra w32 code
1131 * Makefile.am: Add MinGW configuration options, and extra w32 code
1133 * main.c: Determine correct program string (after last \ without .exe).
1134 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1136 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1137 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1138 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1139 environment support.
1141 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1143 * function.c (func_shell): When initializing error_prefix, check
1144 that reading file name is not null. This fixes long-standing
1145 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1147 2005-02-09 Paul D. Smith <psmith@gnu.org>
1149 * maintMakefile: Update the CVS download URL to simplify them.
1150 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1151 downloading the .texi files from Savannah now.
1153 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1155 * main.c (handle_non_switch_argument): Only add variables to
1156 command_variables if they're not already there: duplicate settings
1157 waste space and can be confusing to read.
1159 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1160 this header is never included by non-WINDOWS32 code, and it
1161 requires <config.h> to define which isn't always included first.
1163 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1164 testing MINGW32 versions.
1166 * main.c (log_working_directory): flush stdout to be sure the WD
1167 change is printed before any stderr messages show up.
1169 2005-02-01 Paul D. Smith <psmith@gnu.org>
1171 * maintMakefile (po_repo): Update the GNU translation site URL.
1173 2004-12-01 Paul D. Smith <psmith@gnu.org>
1175 * main.c (main): Change char* env_shell to struct variable shell_var.
1176 * variable.c (target_environment): Use new shell_var.
1178 2004-11-30 Paul D. Smith <psmith@gnu.org>
1180 * configure.in: The old way we avoided creating build.sh from
1181 build.sh.in before build.sh.in exists doesn't work anymore; we
1182 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1183 the help!). This also keeps automake from complaining.
1184 * Makefile.am (README): Add a dummy target so automake won't
1185 complain that this file doesn't exist when we checkout from CVS.
1186 * maintMakefile (.dep_segment): Rewrite this rule since newer
1187 versions of automake don't provide DEP_FILES.
1189 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1191 Implementation of `realpath' and `abspath' built-in functions.
1193 * configure.in: Check for realpath.
1194 * function.c (abspath): Return an absolute file name that does
1195 not contain any `.' or `..' components, nor repeated `/'.
1196 * function.c (func_abspath): For each name call abspath.
1197 * function.c (func_realpath): For each name call realpath
1198 from libc or delegate to abspath if realpath is not available.
1199 * doc/make.texi (Functions for File Names): Document new functions.
1200 * doc/make.texi (Quick Reference): Ditto.
1202 2004-11-28 Paul D. Smith <psmith@gnu.org>
1204 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1205 arguments. Fixes bug #10252.
1207 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1209 * main.c (main): Set SHELL to v_noexport by default. Remember the
1210 original environment setting of SHELL in the env_shell variable.
1211 * main.h: Export new env_shell variable.
1212 * variable.c (target_environment): If we find a v_noexport
1213 variable for SHELL, add a SHELL variable with the env_shell value.
1214 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1215 * doc/make.texi (Variables/Recursion): Ditto.
1217 2004-11-28 Paul D. Smith <psmith@gnu.org>
1219 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1220 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1221 Patch by Alessandro Vesely.
1223 2004-11-12 Paul D. Smith <psmith@gnu.org>
1225 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1226 the command line if it's inside a string.
1227 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1229 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1231 * function.c (func_lastword): New function: return last word
1232 from the list of words.
1233 * doc/make.texi: Document $(lastword ). Fix broken links in
1234 Quick Reference section.
1236 2004-10-06 Paul D. Smith <psmith@gnu.org>
1238 Apply patch from Alessandro Vesely, provided with bug # 9748.
1239 Fix use of tmpnam() to work with Borland C.
1241 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1242 construction of a temporary filename, and call new function
1243 create_batch_filename().
1244 (create_batch_filename) [WINDOWS32]: New function to create a
1247 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1249 * read.c (record_target_var): Expand simple pattern-specific
1251 * variable.c (initialize_file_variables): Do not expand simple
1252 pattern-specific variable.
1254 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1256 * remake.c (update_file_1): When rebuilding makefiles inherit
1257 dontcare flag from a target that triggered update.
1259 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1261 * variable.c (initialize_file_variables): Mark pattern-specific
1262 variable as a per-target and copy export status.
1264 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1266 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1268 * implicit.c (pattern_search): When considering an implicit rule's
1269 prerequisite check that it is actually a target rather then
1270 just an entry in the file hashtable.
1272 2004-09-21 Paul D. Smith <psmith@gnu.org>
1274 * read.c (readstring): Fix some logic errors in backslash handling.
1275 (eval): Remove some unnecessary processing in buffer handling.
1276 (record_target_var): Assert that parse_variable_definition() succeeded.
1277 Reported by: Markus Mauhart <qwe123@chello.at>.
1279 * misc.c: Removed the sindex() function. All instances of this
1280 function were trivially replaceable by the standard strstr()
1281 function, and that function will always have better (or certainly
1282 no worse) performance than the very simple-minded algorithm
1283 sindex() used. This can matter with complex makefiles.
1284 * make.h: Remove the prototype for sindex().
1285 * function.c (subst_expand): Convert sindex() call to strstr().
1286 This means we no longer need to track the TLEN value so remove that.
1287 (func_findstring): Convert sindex() to strstr().
1288 * commands.c (chop_commands): Convert sindex() calls to strstr().
1289 Suggested by: Markus Mauhart <qwe123@chello.at>.
1291 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1292 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1293 If SHELL is set to CMD.EXE then assume it's batch-mode and
1294 non-unixy. I wrote the code differently from the patch, though,
1295 to make it safer. This also resolves bug #9174.
1297 2004-09-20 Paul D. Smith <psmith@gnu.org>
1299 * expand.c (variable_expand_string): Modify to invoke
1300 patsubst_expand() instead of subst_expand(); the latter didn't
1301 handle suffix patterns correctly.
1302 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1303 was used only from variable_expand_string() and is no longer used
1305 (func_subst): Ditto, on call to subst_expand().
1306 (patsubst_expand): Require the percent pointers to point to the
1307 character after the %, not to the % itself.
1308 * read.c (record_files): New call criteria for patsubst_expand().
1309 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1310 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1312 2004-09-19 Paul D. Smith <psmith@gnu.org>
1314 * function.c (subst_expand): Fix a check in by_word: look for a
1315 previous blank if we're beyond the beginning of the string, not
1316 the beginning of the word.
1317 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1319 2004-05-16 Paul D. Smith <psmith@gnu.org>
1321 * remake.c (update_goal_chain): Change the argument specifying
1322 whether we're rebuilding makefiles to be a global variable,
1323 REBUILDING_MAKEFILES.
1324 (complain): Extract the code that complains about no rules to make
1325 a target into a separate function.
1326 (update_file_1): If we tried to rebuild a file during the makefile
1327 rebuild phase and it was dontcare, then no message was printed.
1328 If we then try to build the same file during the normal build,
1329 print a message this time.
1330 (remake_file): Don't complain about un-remake-able files when
1331 we're rebuilding makefiles.
1333 2004-05-11 Paul D. Smith <psmith@gnu.org>
1335 * job.c (construct_command_argv_internal): OS/2 patches from
1336 Andreas Buening <andreas.buening@nexgo.de>.
1338 2004-05-10 Paul D. Smith <psmith@gnu.org>
1340 * remake.c (update_file): Don't walk the double-colon chain unless
1341 this is a double-colon rule. Fix suggested by Boris Kolpackov
1342 <boris@kolpackov.net>.
1344 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1345 * readme.vms: New section describing OpenVMS support and issues.
1346 * default.c (default_variables): Add support for IA64.
1347 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1348 without some privilege aborts make with the error
1349 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1350 pressing Ctrl+Y and the input device is no terminal. The change
1351 catches this error and just continues.
1353 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1355 2004-04-25 Paul D. Smith <psmith@gnu.org>
1357 * commands.c (set_file_variables): Set $< properly in the face of
1358 order-only prerequisites.
1359 Patch from Boris Kolpackov <boris@kolpackov.net>
1361 2004-04-21 Bob Byrnes <byrnes@curl.com>
1363 * main.c (main): Notice failures to remake makefiles.
1365 2004-03-28 Paul D. Smith <psmith@gnu.org>
1367 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1369 * job.c: No default shell for RISC OS.
1370 (load_too_high): Hard-code the return to 1.
1371 (construct_command_argv_internal): No sh_chars or sh_cmds.
1372 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1374 2004-03-20 Paul D. Smith <psmith@gnu.org>
1376 * variable.c (do_variable_definition): Don't append from the
1377 global set if a previous non-appending target-specific variable
1378 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1381 * expand.c (reference_variable): Don't give up on variables with
1382 no value that have the target-specific append flag set: they might
1383 have a value after all. Reported by Oliver Schmidt
1384 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1385 <nikulin@dx1cmd.inp.nsk.su>.
1387 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1388 refer to absolute pathnames in directories that don't exist: some
1389 portion of the makefile could create those directories before we
1390 match the pattern. Fixes bugs #775 and #108.
1392 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1394 * main.c (main): Free makefile_mtimes if we have any.
1395 * README.W32.template: Update documentation for the current status
1396 of the MS-Windows port.
1397 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1398 environment variable is sometimes already defined which causes the
1400 * main.c (debug_signal_handler): Only define this function if
1401 SIGUSR1 is available.
1403 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1405 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1406 * README.OS2.template: Documentation updates.
1407 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1408 link line for safety.
1409 * maintMakefile (build.sh.in): Remove an extraneous ")".
1410 * job.c (child_execute_job): Close saved FDs.
1411 * job.c (exec_command) [OS/2]: exec_command(): If the command
1412 can't be exec'ed and if the shell is not Unix-sh, then try again
1413 with argv = { "cmd", "/c", ... }. Normally, this code is never
1414 reached for the cmd shell unless the command really doesn't exist.
1415 (construct_command_argv_internal) [OS/2]: The code for cmd
1416 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1417 The CMD builtin commands are case insensitive so use strcasecmp().
1419 2004-03-19 Paul D. Smith <psmith@gnu.org>
1421 * read.c (do_define): Re-order line counter increment so the count
1422 is accurate (we were losing one line per define). Reported by
1423 Dave Yost <Dave@Yost.com>.
1425 2004-03-06 Paul D. Smith <psmith@gnu.org>
1427 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1429 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1430 * misc.c (message,error,fatal): Ditto.
1431 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1432 * config.h.W32.template: Ditto.
1433 * config.h-vms.template: Ditto.
1434 * config.ami.template: Ditto.
1436 2004-03-04 Paul D. Smith <psmith@gnu.org>
1438 * README.template: Add a note about broken /bin/sh on SunOS
1439 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1441 * misc.c (message, error, fatal): Don't use "..." if we're using
1442 varargs. ansi2knr should handle this but it doesn't work: it
1443 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1444 done. On many systems (SunOS for example) va_dcl is a #define.
1445 So, force the use of the non-"..." version on pre-ANSI compilers.
1447 * maintMakefile (sign-dist): Create some rules to help automate
1448 the new GNU ftp upload method.
1450 2004-02-24 Paul D. Smith <psmith@gnu.org>
1452 * config.h.W32.template: Add HAVE_STDARG_H
1453 * config.h-vms.template: Ditto.
1454 * config.ami.template: Ditto.
1456 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1458 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1459 * build_w32.bat: Remove extra "+".
1461 2004-02-23 Paul D. Smith <psmith@gnu.org>
1463 * make.h: Create an UNUSED macro to mark unused parameters.
1464 * (many): Clean up warnings by applying UNUSED, fixing
1465 signed/unsigned incompatibilities, etc.
1467 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1469 * filedef.h: Name the command_state enumeration.
1470 * file.c (set_command_state): Use the enumeration in the function
1473 * configure.in: Explicitly set SET_MAKE to empty, to disable
1474 MAKE=make even when no make already exists. Fix bug #3823.
1476 2004-02-22 Paul D. Smith <psmith@gnu.org>
1478 * maintMakefile: Perl script to clean up all non-CVS files. Use
1479 it on all the subdirectories for the cvs-clean target.
1481 * main.c (decode_switches): Require non-empty strings for all our
1482 string command-line options. Fixes Debian bug # 164165.
1484 * configure.in: Check for stdarg.h and varargs.h.
1485 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1486 for printing messages.
1487 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1492 A number of patches for OS/2 support from Andreas Buening
1493 <andreas.buening@nexgo.de>:
1495 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1496 disable the SIGCHLD handler.
1497 (reap_children) [OS/2]: Remove special handling of job_rfd.
1498 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1499 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1500 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1501 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1502 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1505 2004-02-21 Paul D. Smith <psmith@gnu.org>
1507 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1508 <mail@kristov.de> reports that if process_begin() fails we don't
1509 handle the error condition correctly in all cases.
1510 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1511 to have a newline on the message.
1513 * job.c (construct_command_argv_internal): Add "test" to UNIX
1514 sh_cmds[]. Fixes Savannah bug # 7606.
1516 2004-02-04 Paul D. Smith <psmith@gnu.org>
1518 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1519 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1520 Hartmut Becker <Hartmut.Becker@hp.com>.
1522 2004-01-21 Paul D. Smith <psmith@gnu.org>
1524 * job.c (load_too_high): Implement an algorithm to control the
1525 "thundering herd" problem when using -l to control job creation
1526 via the load average. The system only recomputes the load once a
1527 second but we can start many jobs in a second. To solve this we
1528 keep track of the number of jobs started in the last second and
1529 apply a weight to try to guess what a correct load would be.
1530 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1531 Also fixes bug #4693.
1532 (reap_children): Decrease the job count for this second.
1533 (start_job_command): Increase the job count for this second.
1535 * read.c (conditional_line): Expand the text after ifn?def before
1536 checking to see if it's a single word. Fixes bug #7257.
1538 2004-01-09 Paul D. Smith <psmith@gnu.org>
1540 * file.c (print_file): Recurse to print all targets in
1541 double-colon rules. Fixes bug #4518, reported (with patch) by
1542 Andrew Chatham <chatham@google.com>.
1544 2004-01-07 Paul D. Smith <psmith@gnu.org>
1546 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1547 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1548 AC_FUNC_SETVBUF_REVERSED.
1550 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1551 (MAKE Variable): Fix Savannah bug #4898.
1553 * job.c (construct_command_argv_internal): Add "!" to the list of
1554 shell escape chars. POSIX sh allows it to appear before a
1555 command, to negate the exit code. Fixes bug #6404.
1557 * implicit.c (pattern_search): When matching an implicit rule,
1558 remember which dependencies have the ignore_mtime flag set.
1559 Original fix provided in Savannah patch #2349, by Benoit

1562 2003-11-22 Paul D. Smith <psmith@gnu.org>
1564 * README.W32.template (Outputs): Clarification on -j with
1565 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1568 2003-11-02 Paul D. Smith <psmith@gnu.org>
1570 * function.c (func_if): Strip all the trailing whitespace from the
1571 condition, then don't expand it. Fixed bug # 5798.
1573 * expand.c (recursively_expand_for_file): If we're expanding a
1574 variable with no file context, then use the variable's context.
1577 2003-10-21 Paul D. Smith <psmith@gnu.org>
1579 * main.c (log_working_directory): Add newlines to printf()s.
1581 * README.cvs: Add a note to ignore warnings during autoreconf.
1583 * maintMakefile (po_repo): Set a new URL for PO file updates.
1584 (get-config/config.guess get-config/config.sub): Get these files
1585 from the Savannah config project instead of ftp.gnu.org.
1587 2003-10-05 Paul Eggert <eggert@twinsun.com>
1589 * main.c (main): Avoid potential subscript error if environ has
1592 2003-08-22 Paul D. Smith <psmith@gnu.org>
1594 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1595 systems which don't yet implement the C89 standard :-/.
1597 2003-07-18 Paul D. Smith <psmith@gnu.org>
1599 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1600 [WINDOWS32]: Initialize hash.
1602 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1604 * dir.c (read_dirstream): Provide a workaround for broken versions of
1605 the MinGW dirent structure.
1607 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1609 * w32/include/dirent.h: Add __MINGW32__ filter.
1611 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1613 * make.h: Add global declaration of *make_host.
1614 * main.c (print_usage): Remove local declaration of *make_host.
1615 (print_version): Display "This program built for ..." after Copyright
1618 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1620 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1621 execution of "makeinfo --html make.texi".
1623 2003-04-30 Paul D. Smith <psmith@gnu.org>
1625 * build.template: Make some changes to maybe allow this script to
1626 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1628 * README.OS2.template: New file for OS/2 support. Original
1629 contributed by Andreas Buening.
1630 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1633 2003-04-19 Paul D. Smith <psmith@gnu.org>
1635 Fix bug #1405: allow a target to match multiple pattern-specific
1638 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1639 variable.c, where they've always belonged.
1640 * rule.h: Move the prototypes and struct pattern_var as well.
1641 * variable.c (initialize_file_variables): Invoke
1642 lookup_pattern_var() in a loop, until no more matches are found.
1643 If a match is found, create a new variable set for the target's
1644 pattern variables. Then merge the contents of each matching
1645 pattern variable set into the target's pattern variable set.
1646 (lookup_pattern_var): Change this function to be usable
1647 in a loop. It takes a starting position: if NULL, start at the
1648 beginning; if non-NULL, start with the pattern variable after that
1649 position, and return the next matching pattern.
1650 (create_pattern_var): Create a unique instance of
1651 pattern-specific variables for every definition in the makefile.
1652 Don't combine the same pattern together. This allows us to
1653 process the variable handling properly even when the same pattern
1654 is used multiple times.
1655 (parse_variable_definition): New function: break out the parsing
1656 of a variable definition line from try_variable_definition.
1657 (try_variable_definition): Call parse_variable_definition to
1659 (print_variable_data_base): Print out pattern-specific variables.
1660 * variable.h (struct variable): Remember when a variable is
1661 conditional. Also remember its flavor.
1662 (struct pattern_var): Instead of keeping a variable set, we just
1663 keep a single variable for each pattern.
1664 * read.c (record_target_var): Each pattern variable contains only a
1665 single variable, not a set, so create it properly.
1666 * doc/make.texi (Pattern-specific): Document the new behavior.
1668 2003-04-17 Paul D. Smith <psmith@gnu.org>
1670 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1671 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1672 file/directory naming rules for VMS so I can't tell whether this
1675 2003-04-09 Paul D. Smith <psmith@gnu.org>
1677 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1678 DOS-style pathnames: backslash separators and drive specifiers.
1680 2003-03-28 Paul D. Smith <psmith@gnu.org>
1682 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1683 the intermediate flag on all targets. Fixes bug #2515.
1685 2003-03-24 Paul D. Smith <psmith@gnu.org>
1687 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1688 Upgrade to autoconf 2.57 and automake 1.7.3.
1690 * job.c: More OS/2 changes from Andreas Buening.
1692 * file.c (print_file): Fix variable initialization.
1695 * remake.c (notice_finished_file):
1697 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1698 some calls (like readdir()) return NULL in valid situations
1699 without resetting errno. Fixes bug #2846.
1701 2003-02-25 Paul D. Smith <psmith@gnu.org>
1703 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1705 * job.c (_is_unixy_shell) [OS/2]: New function.
1706 Set default shell to /bin/sh.
1707 (reap_children): Close the job_rfd pipe here since we don't use a
1709 (set_child_handler_action_flags): define this to empty on OS/2.
1710 (start_job_command): Close the jobserver pipe and use
1711 child_execute_job() instead of fork/exec.
1712 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1713 rather than exec'ing, then reconfigure stdin/stdout.
1714 (exec_command): Rewrite to use spawn instead of exec. Return the
1717 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1718 in DOS. Handle the TEMP environment variable as in DOS. Don't
1719 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1720 use -j in DOS mode. Use child_execute_job() instead of
1723 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1726 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1727 prototypes that return values.
1729 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1731 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1732 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1734 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1737 2003-02-24 Paul D. Smith <psmith@gnu.org>
1739 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1740 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1741 (child_execute_job) [VMS]: Handle error status properly.
1742 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1744 * function.c (func_shell): Use EINTRLOOP() while reading from the
1745 subshell pipe (Fixes bug #2502).
1746 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1748 * main.c (main): Ditto.
1750 2003-01-30 Paul D. Smith <psmith@gnu.org>
1752 * read.c (eval): eval() was not fully reentrant, because the
1753 collapsed buffer was static. Change it to be an automatic
1754 variable so that eval() can be invoked recursively.
1756 (eval): Apply patch # 1022: fix memory reference error on long
1757 target-specific variable lines.
1758 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1760 * function.c (check_numeric): Combine the is_numeric() function
1761 into this function, since it's only called from one place.
1762 Constify this function. Have it print the incorrect string in the
1763 error message. Fixes bug #2407.
1764 (strip_whitespace): Constify.
1765 (func_if): Constify.
1766 * expand.c (expand_argument): Constify.
1768 2003-01-29 Paul D. Smith <psmith@gnu.org>
1770 Fix bug # 2169, also reported by other people on various systems.
1772 * make.h: Some systems, such as Solaris and PTX, do not fully
1773 implement POSIX-compliant SA_RESTART functionality; important
1774 system calls like stat() and readdir() can still fail with EINTR
1775 even if SA_RESTART has been set on the signal handler. So,
1776 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1777 EINTR for system calls which return -1 or 0 (NULL), respectively,
1779 Also, remove the old atomic_stat()/atomic_readdir() and
1780 HAVE_BROKEN_RESTART handling.
1782 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1784 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1785 * remake.c (touch_file): Ditto.
1787 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1788 * read.c (construct_include_path): Ditto.
1789 * remake.c (name_mtime): Ditto.
1790 * vpath.c (selective_vpath_search): Ditto.
1791 * dir.c (find_directory): Ditto.
1792 (local_stat): Ditto.
1793 (find_directory): Use ENULLLOOP() to wrap opendir().
1794 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1796 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1797 atomic_readdir() handling.
1799 2003-01-22 Paul D. Smith <psmith@gnu.org>
1801 * function.c (func_call): Fix Bug #1744. If we're inside a
1802 recursive invocation of $(call ...), mask any of the outer
1803 invocation's arguments that aren't used by this one, so that this
1804 invocation doesn't "inherit" them accidentally.
1806 2002-12-05 Paul D. Smith <psmith@gnu.org>
1808 * function.c (subst_expand): Valery Khamenia reported a
1809 pathological performance hit when doing substitutions on very
1810 large values with lots of words: turns out we were invoking
1811 strlen() a ridiculous number of times. Instead of having each
1812 call to sindex() call strlen() again, keep track of how much of
1813 the text we've seen and pass the length to sindex().
1815 2002-11-19 Paul D. Smith <psmith@gnu.org>
1817 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1820 2002-11-16 Paul D. Smith <psmith@gnu.org>
1822 * NMakefile.template (OBJS): Add hash.c object file.
1823 * SMakefile.template (srcs): Ditto.
1824 * Makefile.ami (objs): Ditto.
1825 * build_w32.bat: Ditto.
1827 * Makefile.DOS.template: Remove extra dependencies.
1829 2002-10-25 Paul D. Smith <psmith@gnu.org>
1831 * expand.c (install_variable_buffer): New function. Install a new
1832 variable_buffer context and return the previous one.
1833 (restore_variable_buffer): New function. Free the current
1834 variable_buffer context and put a previously saved one back.
1835 * variable.h: Prototypes for {install,restore}_variable_buffer.
1836 * function.c (func_eval): Push a new variable_buffer context
1837 before we eval, then restore the old one when we're done.
1840 * read.c (install_conditionals): New function. Install a new
1841 conditional context and return the previous one.
1842 (restore_conditionals): New function. Free the current
1843 conditional context and put a previously saved one back.
1844 (eval): Use the {install,restore}_conditionals for "include"
1846 (eval_buffer): Use {install,restore}_conditionals to preserve the
1847 present conditional state before we evaluate the buffer.
1850 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1852 (Recursion): Add a variable index entry for CURDIR.
1854 * README.cvs: Update to appropriate versions.
1855 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1856 don't need to copy loadavg.c: automake is smart enough to create
1857 it for me. Still have a bug in automake related to ansi2knr tho.
1859 2002-10-14 Paul D. Smith <psmith@gnu.org>
1861 * remake.c (notice_finished_file): Only touch targets if they have
1862 at least one command (as per POSIX). Resolve Bug #1418.
1864 * *.c: Convert to using ANSI C-style function definitions.
1865 * Makefile.am: Enable the ansi2knr feature of automake.
1866 * configure.in: ditto.
1868 2002-10-13 Paul D. Smith <psmith@gnu.org>
1870 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1871 for automatic variable values like $^, etc. In the case of very
1872 large lists of prerequisites this causes problems. Instead reuse
1873 a static buffer (resizeable) for each variable.
1875 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1876 target-specific variable definitions. Check for it and set an
1878 (record_target_var): Set the export field to v_export if the
1879 "exported" flag is set.
1880 * doc/make.texi (Target-specific): Document the ability to use
1883 * doc/make.texi: Change the name of the section on automatic
1884 variables from "Automatic" to "Automatic Variables". Added text
1885 clarifying the scope of automatic variables.
1887 2002-10-04 Paul D. Smith <psmith@gnu.org>
1889 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1891 (record_files): Ditto.
1893 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1894 the search for the '=' to only within the enclosing parens.
1896 2002-10-03 Paul D. Smith <psmith@gnu.org>
1898 Version 3.80 released.
1900 * dir.c: Change hash functions to use K&R function definition style.
1901 * function.c: Ditto.
1903 * variable.c: Ditto.
1905 Update to automake 1.7.
1907 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1908 (pdf): Remove this target as automake now provides one.
1910 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1912 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1914 * makefile.com: Updates for GNU make 3.80.
1915 * makefile.vms: Ditto.
1917 2002-09-23 Paul D. Smith <psmith@gnu.org>
1919 * read.c (enum make_word_type): Remove w_comment.
1920 (get_next_mword): Don't treat comment characters as special; where
1921 this function is used we will never see a comment (it's stripped
1922 before we get here) and treating comments specially means that
1923 targets like "foo\#bar" aren't handled properly.
1925 2002-09-18 Paul D. Smith <psmith@gnu.org>
1927 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1929 * read.c (eval): Expansion of arguments to export/unexport was
1930 ignoring all arguments after the first one. Change the algorithm
1931 to expand the whole line once, then parse the results.
1933 2002-09-17 Paul D. Smith <psmith@gnu.org>
1935 Fix Bug #940 (plus another bug I found while looking at this):
1937 * read.c (record_target_var): enter_file() will add a new entry if
1938 it's a double-colon target: we don't want to do that in this
1939 situation. Invoke lookup_file() and only enter_file() if it does
1940 not already exist. If the file we get back is a double-colon then
1941 add this variable to the "root" double-colon target.
1943 * variable.c (initialize_file_variables): If this file is a
1944 double-colon target but is not the "root" target, then initialize
1945 the root and make the root's variable list the parent of our
1948 2002-09-13 Paul D. Smith <psmith@gnu.org>
1950 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1952 * hash.c (round_up_2): Get rid of a warning.
1954 2002-09-12 Paul D. Smith <psmith@gnu.org>
1956 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1957 so it doesn't complain about getloadavg.c.
1959 * commands.c (set_file_variables): Make sure we always alloca() at
1960 least 1 character for the value of $? (for '\0').
1962 2002-09-11 Paul D. Smith <psmith@gnu.org>
1964 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1965 macro to use RESULT instead of the incorrect _RESULT_.
1967 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1968 and atomic_readdir(). We need to #include dirent.h to get this to
1970 * misc.c (atomic_readdir): Fix typos.
1972 2002-09-10 Paul D. Smith <psmith@gnu.org>
1974 * read.c (eval): Expand variable lists given to export and
1975 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1976 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1978 * doc/make.texi (Variables/Recursion): Document this.
1979 (Conditional Syntax): And here.
1981 2002-09-09 Paul D. Smith <psmith@gnu.org>
1983 * configure.in: Check for memmove().
1985 2002-09-07 Paul D. Smith <psmith@gnu.org>
1987 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1988 Michael Sterrett <msterret@coat.com> reports that while it has
1989 SA_RESTART, it does not work properly.
1991 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1992 that invokes stat() and loops to do it again if it returns EINTR.
1993 (atomic_readdir): Ditto, with readdir().
1995 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1996 and readdir() to atomic_stat() and atomic_readdir().
1998 2002-09-04 Paul D. Smith <psmith@gnu.org>
2000 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2001 reports that GNU make sometimes doesn't recognize that targets can
2002 be made, when directories can be created as prerequisites. He
2003 reports that changing the order of predicates in the DEP->changed
2004 flag test so that lookup_file() is always performed, solves this
2007 2002-08-08 Paul D. Smith <psmith@gnu.org>
2009 * configure.in: Require a newer version of gettext.
2011 * misc.c (perror_with_name): Translate the format string (for
2012 right-to-left language support).
2013 (pfatal_with_name): Ditto.
2015 * main.c: Create a static array of strings to store the usage
2016 text. This is done to facilitate translations.
2017 (struct command_switch): Remove argdesc and description fields.
2018 (switches): Remove values for obsolete fields.
2019 (print_usage): Print each element of the usage array.
2021 * hash.c: Change function definitions to be K&R style.
2023 2002-08-02 Paul D. Smith <psmith@gnu.org>
2025 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2026 this one because it's too hard to get right. We'll look at it for
2028 * main.c (main): Don't create the .TARGETS variable.
2029 * variable.c (handle_special_var): Don't handle .TARGETS.
2031 2002-08-01 Paul D. Smith <psmith@gnu.org>
2033 * main.c (switches): Add a new option, -B (--always-make). If
2034 specified, make will rebuild all targets that it encounters even
2035 if they don't appear to be out of date.
2036 (always_make_flag): New flag.
2037 * make.h: Extern always_make_flag.
2038 * remake.c (update_file_1): Check always_make_flag; if it's set we
2039 will always rebuild any target we can, even if none of its
2040 prerequisites are newer.
2043 * doc/make.texi (Shell Function): Make it clear that make
2044 variables marked as "export" are not passed to instances of the
2047 Add new introspection variable .VARIABLES and .TARGETS.
2049 * variable.c (handle_special_var): New function. If the variable
2050 reference passed in is "special" (.VARIABLES or .TARGETS),
2051 calculate the new value if necessary. .VARIABLES is handled here:
2052 walk through the hash of defined variables and construct a value
2053 which is a list of the names. .TARGETS is handled by
2054 build_target_list().
2055 (lookup_variable): Invoke handle_special_var().
2056 * file.c (build_target_list): Walk through the hask of known files
2057 and construct a list of the names of all the ones marked as
2059 * main.c (main): Initialize them to empty (and as simple variables).
2060 * doc/make.texi (Special Variables): Document them.
2061 * NEWS: Mention them.
2063 * variable.h (struct variable): Add a new flag "exportable" which
2064 is true if the variable name is valid for export.
2065 * variable.c (define_variable_in_set): Set "exportable" when a new
2066 variable is defined.
2067 (target_environment): Use the "exportable" flag instead of
2068 re-checking the name here... an efficiency improvement.
2070 2002-07-31 Paul D. Smith <psmith@gnu.org>
2072 * config.h-vms.template: Updates to build on VMS. Thanks to
2073 Brian_Benning@aksteel.com for helping verify the build.
2074 * makefile.com: Build the new hash.c file.
2075 * hash.h: Use strcpmi(), not stricmp(), in the
2076 HAVE_CASE_INSENSITIVE_FS case.
2078 2002-07-30 Paul D. Smith <psmith@gnu.org>
2080 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2081 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2082 Reported by <Brian_Benning@aksteel.com>.
2084 2002-07-10 Paul D. Smith <psmith@gnu.org>
2086 * variable.c (pop_variable_scope): Remove variable made unused by
2087 new hash infrastructure.
2088 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2089 comparisons as well as name comparisons.
2090 * variable.h: Add a prototype for new hash_init_function_table().
2091 * file.c (lookup_file): Remove variables made unused by new hash
2093 * dir.c (directory_contents_hash_2): Missing return of hash value.
2094 (dir_contents_file_exists_p): Remove variables made unused by new
2095 hash infrastructure.
2098 Installed Greg McGary's integration of the hash functions from the
2099 GNU id-utils package:
2101 2002-07-10 Greg McGary <greg@mcgary.org>
2103 * scripts/functions/filter-out: Add literals to to the
2104 pattern space in order to add complexity, and trigger
2105 use of an internal hash table. Fix documentation strings.
2106 * scripts/targets/INTERMEDIATE: Reverse order of files
2107 passed to expected `rm' command.
2109 2002-07-10 Greg McGary <greg@mcgary.org>

2199 (print_variable_set): Likewise.
2201 2002-07-10 Paul D. Smith <psmith@gnu.org>
2203 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2204 prerequisite list. A real SysV make will expand the entire
2205 prerequisites list _twice_: we don't do that as it's a big
2206 backward-compatibility problem. We only replace those specific
2209 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2210 references left in the list of prerequisites. Check for .POSIX as
2211 we record targets, so we can disable non-POSIX behavior while
2212 reading makefiles as well as running them.
2213 (eval): Check the prerequisite list to see if we have anything
2214 that looks like a SysV prerequisite variable reference.
2216 2002-07-09 Paul D. Smith <psmith@gnu.org>
2218 * doc/make.texi (Prerequisite Types): Add a new section describing
2219 order-only prerequisites.
2221 * read.c (uniquize_deps): If we have the same file as both a
2222 normal and order-only prereq, get rid of the order-only prereq,
2223 since the normal one supersedes it.
2225 2002-07-08 Paul D. Smith <psmith@gnu.org>
2227 * AUTHORS: Added Greg McGary to the AUTHORS file.
2228 * NEWS: Blurbed order-only prerequisites.
2229 * file.c (print_file): Show order-only deps properly when printing
2232 * maintMakefile: Add "update" targets for wget'ing the latest
2233 versions of various external files. Taken from Makefile.maint in
2236 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2237 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2239 2002-07-07 Paul D. Smith <psmith@gnu.org>
2241 * po/*.po: Remove. We'll use wget to retrieve them at release
2244 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2245 rather than a shell you get an exception. Make sure we look up
2246 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2248 * remake.c (notice_finished_file): Fix handling of -t flag.
2249 Patch provided by Henning Makholm <henning@makholm.net>.
2251 * implicit.c (pattern_search): Some systems apparently run short
2252 of stack space, and using alloca() in this function caused an
2253 overrun. I modified it to use xmalloc() on the two variables
2254 which seemed like they might get large. Fixes Bug #476.
2256 * main.c (print_version): Update copyright notice to conform with
2258 (print_usage): Update help output.
2260 * function.c (func_eval): Create a new make function, $(eval
2261 ...). Expand the arguments, put them into a buffer, then invoke
2262 eval_buffer() on the resulting string.
2263 (func_quote): Create a new function, $(quote VARNAME). Inserts
2264 the value of the variable VARNAME without expanding it any
2267 * read.c (struct ebuffer): Change the linebuffer structure to an
2268 "eval buffer", which can be either a file or a buffer.
2269 (eval_makefile): Move the code in the old read_makefile() which
2270 located a makefile into here: create a struct ebuffer with that
2271 information. Have it invoke the new function eval() with that
2273 (eval_buffer): Create a new function that creates a struct ebuffer
2274 that holds a string buffer instead of a file. Have it invoke
2275 eval() with that ebuffer.
2276 (eval): New function that contains the guts of the old
2277 read_makefile() function: this function parses makefiles. Obtains
2278 data to parse from the provided ebuffer. Some modifications to
2279 make the flow of the function cleaner and clearer. Still could
2280 use some work here...
2281 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2282 contents of the define/endef variable from the ebuffer.
2283 (readstring): Read the next line from a string-style ebuffer.
2284 (readline): Read the next line from an ebuffer. If it's a string
2285 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2288 * dep.h (eval_buffer): Prototype eval_buffer();
2290 * variable.c (do_variable_definition): Make sure that all
2291 non-target-specific variables are registered in the global set.
2292 If we're invoked from an $(eval ...) we might be inside a $(call
2293 ...) or other function which has pushed a variable scope; we still
2294 want to define our variables from evaluated makefile code in the
2297 2002-07-03 Greg McGary <greg@mcgary.org>
2299 * dep.h (struct dep) [ignore_mtime]: New member.
2300 [changed]: convert to a bitfield.
2301 * implicit.c (pattern_search): Zero ignore_mtime.
2302 * main.c (main, handle_non_switch_argument): Likewise.
2303 * rule.c (convert_suffix_rule): Likewise.
2304 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2305 (read_makefile): Parse '|' in prerequisite list.
2306 (uniquize_deps): Consider ignore_mtime when comparing deps.
2307 * remake.c (update_file_1, check_dep): Don't force remake for
2308 dependencies that have d->ignore_mtime.
2309 * commands.c (FILE_LIST_SEPARATOR): New constant.
2310 (set_file_variables): Don't include a
2311 prerequisite in $+, $^ or $? if d->ignore_mtime.
2314 2002-06-18 Paul D. Smith <psmith@gnu.org>
2316 * make.texinfo: Updates for next revision. New date/rev/etc.
2317 Recreate all Info menus. Change license on the manual to the GNU
2318 Free Documentation License. A number of typos.
2319 (Variables Simplify): Don't use "-" before it's defined.
2320 (Automatic Prerequisites): Rewrite the target example to work
2321 properly if the compile fails. Remove incorrect comments about
2322 how "set -e" behaves.
2323 (Text Functions): Move the "word", "wordlist", "words", and
2324 "firstword" functions here, from "File Name Functions".
2325 * make-stds.texi: Update from latest GNU version.
2326 * fdl.texi: (created) Import the latest GNU version.
2328 2002-06-06 Paul D. Smith <psmith@gnu.org>
2330 * variable.c (do_variable_definition): New function: extract the
2331 part of try_variable_definition() that actually sets the value
2332 into a separate function.
2333 (try_variable_definition): Call do_variable_definition() after
2334 parsing the variable definition string.
2335 (define_variable_in_set): Make the name argument const.
2337 * variable.h (enum variable_flavor): Make public.
2338 (do_variable_definition): Create prototype.
2340 * read.c (read_all_makefiles): Create a new built-in variable,
2342 (read_makefile): Add each makefile read in to this variable value.
2344 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2346 * Makefile.DOS.template: Tweak according to changes in the
2347 distribution. Add back the dependencies of *.o files.
2349 * configh.dos.template: Synchronize with config.h.in.
2351 2002-05-09 Paul D. Smith <psmith@gnu.org>
2353 * file.c (file_timestamp_now): Use K&R function declaration.
2355 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2356 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2357 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2358 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2359 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2360 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2361 nlist.n_name is a pointer rather than an array.
2363 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2364 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2365 * configure.in: Use it instead of the old version.
2367 * main.c (main): Prefer setvbuf() to setlinebuf().
2369 2002-05-08 Paul D. Smith <psmith@gnu.org>
2371 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2372 (loadavg_LDADD): Ditto.
2374 2002-04-29 Paul D. Smith <psmith@gnu.org>
2376 * expand.c (recursively_expand_for_file): Rename
2377 recursively_expand() to recursively_expand_for_file() and provide
2378 an extra argument, struct file. If the argument is provided, set
2379 the variable scope to that of the file before expanding.
2380 * variable.h (recursively_expand): Make this a macro that invokes
2381 recursively_expand_for_file() with a NULL file pointer.
2382 * variable.c (target_environment): Call the renamed function and
2383 provide the current file context.
2384 Fixes Debian bug #144306.
2386 2002-04-28 Paul D. Smith <psmith@gnu.org>
2388 Allow $(call ...) user-defined variables to be self-referencing
2389 without throwing an error. Allows implementation of transitive
2390 closures, among other possibly useful things.
2391 Requested by: Philip Guenther <guenther@sendmail.com>
2393 * variable.h (struct variable): Add a new field: exp_count, and
2394 new macros to hold its size and maximum value.
2395 (warn_undefined): Make this a macro.
2396 * variable.c (define_variable_in_set): Initialize it.
2397 * expand.c (recursively_expand): If we detect recursive expansion
2398 of a variable, check the exp_count field. If it's greater than 0
2399 allow the recursion and decrement the count.
2400 (warn_undefined): Remove this (now a macro in variable.h).
2401 * function.c (func_call): Before we expand the user-defined
2402 function, modify its exp_count field to contain the maximum
2403 number of recursive calls we'll allow. After the call, reset it
2406 2002-04-21 Paul D. Smith <psmith@gnu.org>
2408 Modified to use latest autoconf (2.53), automake (1.6.1), and
2409 gettext (0.11.1). We're using gettext's new "external" support,
2410 to avoid including libintl source with GNU make.
2412 * README.cvs: New file. Explain how to build GNU make from CVS.
2414 * configure.in: Modify checking for the system glob library.
2415 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2416 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2417 etc. will manage it correctly). Set an automake conditional
2418 USE_LOCAL_GLOB to decide whether to compile the glob library.
2420 * getloadavg.c (main): Include make.h in the "TEST" program to
2423 * Makefile.am: Remove special rules for loadavg. Replace them
2424 with Automake capabilities for building extra programs.
2426 * signame.c: This file does nothing if the system provide
2427 strsignal(). If not, it implements strsignal(). If the system
2428 doesn't define sys_siglist, then we make our own; otherwise we use
2430 * signame.h: Removed.
2432 * main.c (main): No need to invoke signame_init(). Update copyright.
2434 * ABOUT-NLS: Removed.
2435 * gettext.c: Removed.
2436 * gettext.h: Get a simplified copy from the gettext package.
2438 * i18n/*.po: Moved to po/.
2441 * config/*: Created. Contains package configuration helper files.
2442 * config.guess, config.sub: Moved to config directory.
2444 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2445 Rework to use new-style autoconf features. Use the "external"
2446 mode for gettext. Make the build.sh config file conditional on
2447 whether build.sh.in exists, to avoid autoconf errors.
2448 * acinclude.m4: Removed almost all macros as being obsolete.
2449 Rewrote remaining macros to use AC_DEFINE.
2450 * acconfig.h: Removed.
2452 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2453 conditional to handle customs support. Remove special handling
2456 2002-04-20 Paul D. Smith <psmith@gnu.org>
2458 * function.c (func_call): Don't mark the argument variables $1,
2459 etc. as recursive. They've already been fully expanded so
2460 there's no need to do it again, and doing so strips escaped $'s.
2461 Reported by Sebastian Glita <glseba@yahoo.com>.
2463 * remake.c (notice_finished_file): Walk through double-colon
2464 entries via the prev field, not the next field!
2465 Reported by Greg McGary <greg@mcgary.org>.
2467 * main.c (main): If the user specifies -q and asks for a specific
2468 target which is a makefile, we got an assert. In that case it
2469 turns out we should continue normally instead.
2471 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2473 * i18n/he.po: Installed a new translation.
2475 2002-01-07 Paul D. Smith <psmith@gnu.org>
2477 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2479 2001-12-04 Paul D. Smith <psmith@gnu.org>
2481 * i18n/ja.po: Installed an updated translation.
2483 2001-09-06 Paul Eggert <eggert@twinsun.com>
2485 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2486 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2488 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2490 (main): Get rid of any avoidable limit on stack size.
2492 2001-09-04 Paul D. Smith <psmith@gnu.org>
2494 * i18n/da.po: Installed an updated translation.
2496 2001-08-03 Paul D. Smith <psmith@gnu.org>
2498 * i18n/fr.po: Installed an updated translation.
2499 Resolves Debian bug #106720.
2501 2001-06-13 Paul D. Smith <psmith@gnu.org>
2503 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2506 2001-06-11 Paul D. Smith <psmith@gnu.org>
2508 * i18n/ko.po: Installed a new translation.
2510 2001-05-06 Paul D. Smith <psmith@gnu.org>
2512 Modify the EINTR handling.
2514 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2515 the way in which we manage the file descriptor/signal handler race
2516 trap to be more efficient.
2518 2001-05-06 Paul Eggert <eggert@twinsun.com>
2520 Restart almost all system calls that are interrupted, instead
2521 of worrying about EINTR. The lone exception is the read() for
2524 * configure.in (HAVE_SA_RESTART): New macro.
2525 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2526 * main.c (main): Use SA_RESTART instead of the old,
2527 nonstandard SA_INTERRUPT.
2529 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2530 * main.c (bsd_signal): New function or macro,
2531 if the implementation doesn't supply it.
2532 (The bsd_signal function will be in POSIX 1003.1-200x.)
2533 (HANDLESIG): Remove.
2534 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2536 * make.h (EINTR_SET): Remove.
2537 (SA_RESTART): New macro.
2539 * arscan.c (ar_member_touch): Don't worry about EINTR.
2540 * function.c (func_shell): Likewise.
2541 * job.c (reap_children, free_child, new_job): Likewise.
2542 * main.c (main): Likewise.
2543 * remake.c (touch_file, name_mtime): Likewise.
2545 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2546 if fstat failed with errno!=EINTR, the error was ignored.
2548 * job.c (set_child_handler_action_flags): New function.
2549 (new_job): Use it to temporarily clear the SIGCHLD action flags
2550 while reading the token.
2552 2001-05-02 Paul D. Smith <psmith@gnu.org>
2554 * job.c (start_job_command): Don't add define/endef per-line flags
2555 to the top-level flags setting.
2557 2001-04-03 Paul D. Smith <psmith@gnu.org>
2559 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2560 bit on error, so check for odd return values, not non-0 return
2562 (VMS_get_member_info): Calculate the timezone differences correctly.
2563 Reported by John Fowler <jfowler@nyx.net>.
2566 2001-03-14 Paul D. Smith <psmith@gnu.org>
2568 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2569 value before invoking define_variable().
2570 Reported by John Fowler <jfowler@nyx.net>.
2572 2001-02-07 Paul D. Smith <psmith@gnu.org>
2574 * read.c (record_target_var): If we reset the variable due to a
2575 command-line variable setting overriding it, turn off the "append"
2578 2001-01-17 Paul D. Smith <psmith@gnu.org>
2580 * variable.c (lookup_variable) [VMS]: When getting values from the
2581 environment, allocate enough space for the _value_ plus escapes,
2582 not enough space for the name plus escapes :-/.
2583 Reported by John Fowler <jfowler@nyx.net>.
2585 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2586 warnings that make generates, so it doesn't look like an error.
2587 Reported by Karl Berry <karl@gnu.org>.
2590 Fix for PR/2020: Rework appended target-specific variables. I'm
2591 fairly confident this algorithm is finally correct.
2593 * expand.c (allocated_variable_append): Rewrite. Instead of
2594 expanding each appended variable then adding all the expanded
2595 strings together, we append all the unexpanded values going up
2596 through the variable set contexts, then expand the final result.
2597 This behaves just like non-target-specific appended variable
2598 values, while the old way didn't in various corner cases.
2599 (variable_append): New function: recursively append the unexpanded
2600 value of a variable, walking from the outermost variable scope to
2602 * variable.c (lookup_variable): Remove the code that looked up the
2603 variable set list if the found variable was "append". We don't
2605 (lookup_variable_in_set): Make this non-static so we can use it
2607 (try_variable_definition): Use lookup_variable_in_set() rather
2608 than faking out current_variable_set_list by hand (cleanup).
2609 * variable.h: Add a prototype for the now non-static
2610 lookup_variable_in_set().
2612 2000-11-17 Paul D. Smith <psmith@gnu.org>
2614 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2615 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2616 before throwing a fit.
2618 2000-11-17 Paul D. Smith <psmith@gnu.org>
2620 * read.c (readline): CRLF calculations had a hole, if you hit the
2621 buffer grow scenario just right. Reworked the algorithm to avoid
2622 the need for len or lastlen at all. Problem description with
2623 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2625 2000-10-24 Paul D. Smith <psmith@gnu.org>
2627 * gettext.c (SWAP): Declare this with the prototype, otherwise
2628 some systems don't work (non-32-bit? Reported for Cray T3E).
2629 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2631 2000-10-05 Paul D. Smith <psmith@gnu.org>
2633 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2634 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2636 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2638 2000-09-22 Paul D. Smith <psmith@gnu.org>
2640 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2641 parts of the real gettext.h here, and we expect to really include
2642 the real gettext.h later. If we keep this #define, it's ignored.
2644 2000-09-21 Paul D. Smith <psmith@gnu.org>
2646 * main.c (log_working_directory): Rework the text to use complete
2647 sentences, to make life simpler for the translators.
2649 2000-08-29 Paul D. Smith <psmith@gnu.org>
2651 * file.c (remove_intermediates): Print a debug message before we
2652 remove intermediate files, so the user (if she uses -d) knows
2655 2000-08-21 Paul D. Smith <psmith@gnu.org>
2657 * variable.c (try_variable_definition): Change how we handle
2658 target-specific append variable defns: instead of just setting the
2659 value, expand it as an append _but_ only within the current
2660 target's context. Otherwise we lose all but the last value if the
2661 variable is appended more than once within the current target
2662 context. Fixes PR/1831.
2664 2000-08-16 Paul D. Smith <psmith@gnu.org>
2666 * function.c (func_shell): Nul-terminate the buffer before
2667 printing an exec error message (just in case it's not!).
2668 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2670 2000-07-25 Paul D. Smith <psmith@gnu.org>
2672 * job.c (construct_command_argv_internal): Add "~" to the list of
2673 sh_chars[] which disallow optimizing out the shell call.
2675 2000-07-23 Paul Eggert <eggert@twinsun.com>
2677 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2678 supersedes --disable-nsec-timestamps.
2679 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2680 * README: Remove --disable-nsec-timestamps.
2682 * filedef.h (struct file.low_resolution_time): New member.
2683 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2684 * remake.c (update_file_1):
2685 Avoid spurious rebuilds due to low resolution time stamps,
2686 generalizing the earlier code that applied only to archive members.
2687 (f_mtime): Archive members always have low resolution time stamps.
2689 * configure.in: Remove --disable-nsec-timestamps, as this has
2690 been superseded by .LOW_RESOLUTION_TIME.
2692 2000-07-23 Paul Eggert <eggert@twinsun.com>
2694 * configure.in (enable_nsec_timestamps): Renamed from
2695 make_cv_nsec_timestamps, since enable/disable options
2696 shouldn't be cached.
2698 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2699 and Paul Eggert <eggert@twinsun.com>
2701 * file.c (file_timestamp_now):
2702 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2703 so that clock_gettime is not linked unless needed.
2705 * filedef.h (FILE_TIMESTAMP_HI_RES):
2706 Remove definition; "configure" now does this.
2708 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2709 to before high resolution file timestamp check,
2710 since that check now uses uintmax_t.
2711 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2712 high resolution file timestamps.
2713 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2714 so that we don't link in clock_gettime unnecessarily.
2716 2000-07-17 Paul D. Smith <psmith@gnu.org>
2718 * i18n/ja.po: New version of the translation file.
2720 2000-07-07 Paul D. Smith <psmith@gnu.org>
2722 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2723 the offset calculation.
2724 (name_mtime): Replace EINTR test with EINTR_SET macro.
2726 2000-07-07 Paul Eggert <eggert@twinsun.com>
2730 * remake.c (update_file_1):
2731 Avoid spurious rebuilds of archive members due to their
2732 timestamp resolution being only one second.
2733 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2734 the clock's resolution being lower than file timestamps'.
2735 When warning about future timestamps, report only the discrepancy,
2736 not the absolute value of the timestamp and the current time.
2738 * file.c (file_timestamp_now): New arg RESOLUTION.
2739 * filedef.h (file_timestamp_now): Likewise.
2740 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2742 2000-07-05 Paul D. Smith <psmith@gnu.org>
2744 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2745 to listp. Fixes PR/1793.
2747 2000-06-26 Paul Eggert <eggert@twinsun.com>
2749 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2751 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2753 * remake.c (f_mtime): Remove unused var memtime.
2755 2000-06-25 Martin Buchholz <martin@xemacs.org>
2757 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2758 Ran spell-check on make.texinfo.
2760 2000-06-23 Paul D. Smith <psmith@gnu.org>
2762 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2763 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2764 * make.h: Define these macros.
2766 * Version 3.79.1 released.
2768 * configure.in: Add a new option, --disable-nsec-timestamps, to
2769 avoid using sub-second timestamps on systems that support it. It
2770 can lead to problems, e.g. if your makefile relies on "cp -p".
2771 * README.template: Document the issue with "cp -p".
2773 * config.guess, config.sub: Updated.
