15 support from automake, as described in the Texinfo manual.
17 2006-03-25 Eli Zaretskii <eliz@gnu.org>
19 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
20 with lastslash, since the latter points to filename, not to
22 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
23 Declare and define sh_chars_sh[].
25 2006-03-23 Paul D. Smith <psmith@gnu.org>
27 * configure.in: Look for build.sh.in in $srcdir so it will be
28 built for remote configurations as well.
30 * Makefile.am: Make sure to clean up build.sh during distclean.
31 Fixes Savannah bug #16166.
33 * misc.c (log_access): Takes a const char *.

40 if we have prerequisites that need second expansion. Fixes
43 2006-03-19 Paul D. Smith <psmith@gnu.org>
45 * remake.c (update_file): Add alloca(0) to clean up alloca'd
46 memory on hosts that don't support it directly.
48 * README.cvs: Add information on steps for making a release (to
49 make sure I don't forget any).
51 * main.c (clean_jobserver): Move jobserver cleanup code into a new
53 (die): Cleanup code was removed from here; call the new function.
54 (main): If we are re-execing, clean up the jobserver first so we
55 don't leak file descriptors.
56 Fix bug reported by Craig Fithian <craig.fithian@citigroup.com>.
58 2006-03-17 Paul D. Smith <psmith@gnu.org>
60 * maintMakefile (do-po-update): Rewrite this rule to clean up and
61 allow multiple concurrent runs.
62 Patch from Joseph Myers <joseph@codesourcery.com>
64 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
66 * dep.h (struct dep): Add the stem field.
67 * misc.c (alloc_dep, free_dep): New functions.

69 (free_dep_chain): Use free_dep.
70 * read.c (record_files): Store stem in the dependency line.

79 2006-03-14 Paul D. Smith <psmith@gnu.org>
81 * expand.c (variable_append): Instead of appending everything then
82 expanding the result, we expand (or not, if it's simple) each part
84 (allocated_variable_append): Don't expand the final result.
85 Fixes Savannah bug #15913.
87 2006-03-09 Paul Smith <psmith@gnu.org>
89 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
90 listed non-existent files as changed. Turns out there's a bug in
91 the Linux kernel builds which means that this change causes
92 everything to rebuild every time. We will re-introduce this fix
93 in the next release, to give them time to fix their build system.
94 Fixes Savannah bug #16002.
95 Introduces Savannah bug #16051.
97 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
98 we *don't* find UNIX "/".
99 Reported by David Ergo <david.ergo@alterface.com>
101 2006-03-04 Eli Zaretskii <eliz@gnu.org>
103 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
104 locator function find_and_set_default_shell if SHELL came from the
107 2006-02-20 Paul D. Smith <psmith@gnu.org>
109 * variable.c (merge_variable_set_lists): It's legal for *setlist0
110 to be null; don't core in that case.
112 2006-02-19 Paul D. Smith <psmith@gnu.org>
114 * commands.c (set_file_variables): Realloc, not malloc, the static
115 string values to avoid memory leaks.
117 * expand.c (recursively_expand_for_file): Only set reading_file to
118 an initialized value.
120 * implicit.c (pattern_search): We need to make a copy of the stem
121 if we get it from an intermediate dep, since those get freed.
123 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
125 (enter_file) [VMS]: Ditto.
126 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
128 2006-02-24 Eli Zaretskii <eliz@gnu.org>

132 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
133 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
134 the calls to _beginthreadex.
136 * expand.c (recursively_expand_for_file): Initialize `save' to
137 prevent compiler warnings.
139 2006-02-18 Eli Zaretskii <eliz@gnu.org>
141 * job.c (construct_command_argv_internal): Don't create a temporary
142 script/batch file if we are under -n. Call _setmode to switch the
143 script file stream to text mode.
145 2006-02-17 Paul D. Smith <psmith@gnu.org>
147 * variable.c (merge_variable_set_lists): Don't try to merge the
148 global_setlist. Not only is this useless, but it can lead to
149 circularities in the linked list, if global_setlist->next in one
150 list gets set to point to another list which also ends in
152 Fixes Savannah bug #15757.
154 2006-02-15 Paul D. Smith <psmith@gnu.org>
156 Fix for Savannah bug #106.
158 * expand.c (expanding_var): Keep track of which variable we're
159 expanding. If no variable is being expanded, it's the same as
161 * make.h (expanding_var): Declare it.
162 * expand.c (recursively_expand_for_file): Set expanding_var to the
163 current variable we're expanding, unless there's no file info in
164 it (could happen if it comes from the command line or a default
165 variable). Restore it before we exit.
166 * expand.c (variable_expand_string): Use the expanding_var file
167 info instead of the reading_file info.
168 * function.c (check_numeric): Ditto.
170 (func_wordlist): Ditto.
172 (expand_builtin_function): Ditto.
173 (handle_function): Ditto.
175 2006-02-14 Paul D. Smith <psmith@gnu.org>
177 * read.c (eval): Even if the included filenames expands to the
178 empty string we still need to free the allocated buffer.
180 * implicit.c (pattern_search): If we allocated a variable set for
181 an impossible file, free it.
182 * variable.c (free_variable_set): New function.
183 * variable.h: Declare it.
185 * read.c (read_all_makefiles): Makefile names are kept in the
186 strcache, so there's never any need to alloc/free them.
189 * main.c (main): Add "archives" to the .FEATURES variable if
190 archive support is enabled.
191 * doc/make.texi (Special Variables): Document it.
193 2006-02-13 Paul D. Smith <psmith@gnu.org>
195 * implicit.c (pattern_search): Add checking for DOS pathnames to
196 the pattern rule target LASTSLASH manipulation.
197 Fixes Savannah bug #11183.
199 2006-02-11 Paul D. Smith <psmith@gnu.org>
201 * (ALL FILES): Updated copyright and license notices.
203 2006-02-10 Paul D. Smith <psmith@gnu.org>
205 A new internal capability: the string cache is a read-only cache
206 of strings, with a hash table interface for fast lookup. Nothing
207 in the cache will ever be freed, so there's no need for reference
208 counting, etc. This is the beginning of a full solution for
209 Savannah bug #15182, but for now we only store makefile names here.
211 * strcache.c: New file. Implement a read-only string cache.
212 * make.h: Add prototypes for new functions.
213 * main.c (initialize_global_hash_tables): Initialize the string cache.
214 (print_data_base): Print string cache stats.
215 * read.c (eval_makefile): Use the string cache to store makefile
216 names. Rewrite the string allocation to be sure we free everything.
218 2006-02-10 Eli Zaretskii <eliz@gnu.org>
220 * dir.c (dir_contents_file_exists_p): Don't opendir if the
221 directory time stamp didn't change, except on FAT filesystems.
222 Suggested by J. David Bryan <jdbryan@acm.org>.
224 2006-02-09 Paul D. Smith <psmith@gnu.org>
226 * function.c (func_or): Implement a short-circuiting OR function.
227 (func_and): Implement a short-circuiting AND function.
228 (function_table_init): Update the table with the new functions.
229 * doc/make.texi (Conditional Functions): Changed the "if" section
230 to one on general conditional functions. Added documentation for
231 $(and ...) and $(or ...) functions.
232 * NEWS: Note new $(and ...) and $(or ...) functions.
234 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
236 * job.h (struct child): Add the dontcare bitfield.
237 * job.c (new_job): Cache dontcare flag.
238 * job.c (reap_children): Use cached dontcare flag instead of the
239 one in struct file. Fixes Savannah bug #15641.
241 2006-02-06 Paul D. Smith <psmith@gnu.org>
243 * vpath.c (selective_vpath_search): If the file we find has a
244 timestamp from -o or -W, use that instead of the real time.
245 * remake.c (f_mtime): If the mtime is a special token from -o or
246 -W, don't overwrite it with the real mtime.
247 Fixes Savannah bug #15341.

257 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
258 * README.cvs: Updates for building from CVS.
260 2006-02-05 Paul D. Smith <psmith@gnu.org>
262 * file.c (enter_file): Keep track of the last double_colon entry,

264 Fixes Savannah bug #15533.
265 * filedef.h (struct file): Add a new LAST pointer.
267 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
268 the comparison. For 64-bits systems the result of the subtraction
269 might not fit into an int. Use comparison instead.
270 Fixes Savannah bug #15534.
272 * doc/make.texi: Update the chapter on writing commands to reflect
273 the changes made in 3.81 for backslash/newline and SHELL handling.

291 * prepare_w32.bat: Remove this file from the distribution.
293 2006-01-21 Eli Zaretskii <eliz@gnu.org>
295 * remake.c (update_goal_chain): Set g->changed instead of
296 incrementing it, as it is only 8-bit wide, and could overflow if
297 many commands got started in update_file.
299 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
301 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
302 MAXIMUM_WAIT_OBJECTS.

308 (process_easy): Don't start new processes if all slots are used up.
310 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
311 are already more children than sub_proc.c can handle, behave as if
312 the load were too high.
313 (start_job_command): Fix a typo in error message when process_easy
316 2006-01-14 Eli Zaretskii <eliz@gnu.org>
318 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
319 the shell is not sh.exe.
321 * job.c (create_batch_file): Renamed from create_batch_filename;
322 all callers changed. Don't close the temporary file; return its
323 file descriptor instead. New arg FD allows to return the file
325 (construct_command_argv_internal): Use _fdopen instead of fopen to
328 2006-01-04 Paul D. Smith <psmith@gnu.org>
330 * readme.vms: Updates for case-insensitive VMS file systems from
331 Hartmut Becker <Hartmut.Becker@hp.com>.

342 * remake.c (update_file_1): Mark a prerequisite changed if it
345 * read.c (eval): Be sure to strip off trailing whitespace from the
346 prerequisites list properly. Also, initialize all fields in
347 struct dep when creating a new one.
349 2005-12-28 Paul D. Smith <psmith@gnu.org>
351 * config.h.W32.template [WINDOWS32]: Add in some pragmas to

355 2005-12-17 Eli Zaretskii <eliz@gnu.org>
357 * doc/make.texi (Execution): Add a footnote about changes in
358 handling of backslash-newline sequences. Mention the differences
359 on MS-DOS and MS-Windows.
361 * NEWS: More details about building the MinGW port and a pointer
362 to README.W32. Fix the section name that describes the new
363 backward-incompatible processing of backslash-newline sequences.
364 The special processing of SHELL set to "cmd" is only relevant to
365 MS-Windows, not MS-DOS.
367 2005-12-17 Eli Zaretskii <eliz@gnu.org>
369 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
370 to DWORD, to avoid compiler warnings.
371 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and

380 (Environment): Fix punctuation.
381 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
382 (Shell Function, Target-specific): Add @: after "vs."
384 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
386 * read.c (record_target_var): Initialize variable's export field
387 with v_default instead of leaving it "initialized" by whatever
388 garbage happened to be on the heap.
390 2005-12-12 Paul D. Smith <psmith@gnu.org>
392 * make.1: Fix some display errors and document all existing options.
393 Patch provided by Mike Frysinger <vapier@gentoo.org>.
395 2005-12-11 Paul D. Smith <psmith@gnu.org>
397 * implicit.c (pattern_search): If 2nd expansion is not set for
398 this implicit rule, replace the pattern with the stem directly,
399 and don't re-expand the variable list. Along with the other
400 .SECONDEXPANSION changes below, fixes bug #13781.
402 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
404 * implicit.c (pattern_search): Mark other files that this rule
405 builds as targets so that they are not treated as intermediates

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

428 2005-10-26 Paul Smith <psmith@gnu.org>
430 * read.c (record_files): Don't set deps flags if there are no deps.
431 * maintMakefile: We only need to build the templates when we are
432 creating a distribution, so don't do it for "all".
434 2005-10-24 Paul D. Smith <psmith@gnu.org>
436 Make secondary expansion optional: its enabled by declaring the
437 special target .SECONDEXPANSION.
439 * NEWS: Update information on second expansion capabilities.
440 * doc/make.texi (Secondary Expansion): Document the
441 .SECONDEXPANSION special target and its behavior.

444 (free_dep_chain): Declare a prototype.
445 * file.c (parse_prereqs): New function: break out some complexity
447 (expand_deps): If we aren't doing second expansion, replace % with
448 the stem for static pattern rules. Call the new function.
449 * filedef.h (parse_prereqs): Declare a prototype.
450 * implicit.c (pattern_search): Initialize the new staticpattern
452 * main.c (second_expansion): Declare a global variable to remember

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

460 second_expansion global if it's found.
461 Use the new free_dep_chain() instead of doing it by hand.
462 Set the staticpattern field for prereqs of static pattern targets.
464 2005-10-16 Paul D. Smith <psmith@gnu.org>
466 * main.c (main): Set CURDIR to be a file variable instead of a
467 default, so that values of CURDIR inherited from the environment
468 won't override the make value.
470 2005-09-26 Paul D. Smith <psmith@gnu.org>
472 * job.c (construct_command_argv_internal): If the line is empty
473 remember to free the temporary argv strings.
476 2005-09-16 Paul D. Smith <psmith@gnu.org>

480 Reported by Mark Eichin <eichin@metacarta.com>
482 2005-08-29 Paul D. Smith <psmith@gnu.org>
484 * function.c (func_error): On Windows, output from $(info ...)
485 seems to come in the wrong order. Try to force it with fflush().
487 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
489 * read.c (record_files): Move code that sets stem for static
490 pattern rules out of the if (!two_colon) condition so it is
491 also executed for two-colon rules. Fixes Savannah bug #13881.
493 2005-08-08 Paul D. Smith <psmith@gnu.org>
495 * make.h: Don't test that __STDC__ is non-0. Some compilers
496 (Windows for example) set it to 0 to denote "ISO C + extensions".
499 2005-08-07 Paul D. Smith <psmith@gnu.org>
501 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
502 conditional (slightly different version of a fix from Eli).
504 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
505 If make is running in parallel without -k and two jobs die in a
506 row, but not too close to each other, then make will quit without
507 waiting for the rest of the jobs to die.
509 * main.c (die): Don't reset err before calling reap_children() the
510 second time: we still want it to be in the error condition.
511 * job.c (reap_children): Use a static variable, rather than err,
512 to control whether or not the error message should be printed.
514 2005-08-06 Eli Zaretskii <eliz@gnu.org>
516 * w32/subproc/sub_proc.c: Include signal.h.
517 (process_pipe_io, process_file_io): Pass a pointer to a local
518 DWORD variable to GetExitCodeProcess. If the exit code is
519 CONTROL_C_EXIT, put SIGINT into pproc->signal.
521 * job.c [WINDOWS32]: Include windows.h.
522 (main_thread) [WINDOWS32]: New global variable.
523 (reap_children) [WINDOWS32]: Get the handle for the main thread
524 and store it in main_thread.
526 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
527 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
528 doing anything else. When we are done, close the main thread
529 handle and exit with status 130.
531 2005-07-30 Eli Zaretskii <eliz@gnu.org>
533 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
536 * main.c (find_and_set_default_shell): If found a DOSish shell,
537 set sh_found and the value of default_shell, and report the
538 findings in debug mode.
540 * job.c (construct_command_argv_internal): Check unixy_shell, not
541 no_default_sh_exe, to decide whether to use Unixy or DOSish
544 * README.W32: Update with info about the MinGW build.
546 * build_w32.bat: Support MinGW.
548 * w32/subproc/build.bat: Likewise.
550 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
553 * function.c (windows32_openpipe): Fix format strings for printing
556 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
558 (start_job_command): Fix format string for printing the result of
560 (start_job_command) [WINDOWS32]: Do not define.
561 (exec_command): Fix format string for printing HANDLE args.
563 * main.c (handle_runtime_exceptions): Fix sprintf format strings
564 to avoid compiler warnings.
565 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
566 (Note: some of these fixes were submitted independently by J. Grant)
568 2005-07-30 J. Grant <jg@jguk.org>
570 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
571 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
572 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
574 2005-07-15 Paul Smith <psmith@gnu.org>
576 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
577 we don't have a POSIX shell, then revert to the old
578 backslash-newline behavior (where they are stripped).
581 2005-07-08 Paul D. Smith <psmith@gnu.org>
583 * config.h.W32.template: Reorder to match the standard config.h,
584 for easier comparisons.
585 From J. Grant <jg@jguk.org>
587 * maintMakefile: Remove .dep_segment before overwriting it, in
588 case it's not writable or noclobber is set.
589 * expand.c (variable_expand_string): Cast result of pointer
590 arithmetic to avoid a warning.
591 * main.c (switches): Add full-fledged final initializer.
593 2005-07-06 Paul D. Smith <psmith@gnu.org>
595 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
596 * signame.c (strsignal): If we found _sys_siglist[] or
597 __sys_siglist[] use those instead of sys_siglist[].
598 From Albert Chin <china@thewrittenword.com>
600 2005-07-04 Paul D. Smith <psmith@gnu.org>
602 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
603 globfree(); set up to use the GNU versions.
604 From Martin Zinser <zinser@zinser.no-ip.info>
606 2005-07-03 Paul D. Smith <psmith@gnu.org>
608 From J. Grant <jg@jguk.org>:
610 * README.W32.template: Update the Windows and tested MSVC versions.
611 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
612 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
613 * build_w32.bat: Ditto.
614 * w32/subproc/build.bat: Ditto.
616 2005-06-28 Paul D. Smith <psmith@gnu.org>
618 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
619 declaration was checked but not present.
621 2005-06-27 Paul D. Smith <psmith@gnu.org>
623 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
624 to unsigned long. Fixes Savannah bug #13550.
626 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
627 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
628 Fixes Savannah bug #13551.
630 2005-06-26 Paul D. Smith <psmith@gnu.org>
632 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
633 it if ANSI_STRING is not set.
635 2005-06-25 Paul D. Smith <psmith@gnu.org>
637 * read.c (eval): If no filenames are passed to any of the
638 "include" variants, don't print an error.
639 * doc/make.texi (Include): Document this.
640 Fixes Savannah bug #1761.
642 * job.c (construct_command_argv_internal): Sanitize handling of
643 backslash/newline pairs according to POSIX: that is, keep the
644 backslash-newline in the command script, but remove a following
645 TAB character, if present. In the fast path, make sure that the
646 behavior matches what the shell would do both inside and outside
647 of quotes. In the slow path, quote the backslash and put a
648 literal newline in the string.
649 Fixes Savannah bug #1332.
650 * doc/make.texi (Execution): Document the new behavior and give
652 * NEWS: Make a note of the new behavior.
654 * make.h [WINDOWS32]: #include <direct.h>.
655 Fixes Savannah bug #13478.
657 * remake.c (name_mtime): If the stat() of a file fails and the -L
658 option was given and the file is a symlink, take the best mtime of
659 the symlink we can get as the mtime of the file and don't fail.
660 Fixes Savannah bug #13280.
662 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
663 If it's set, then don't stop on STOPCHARs or BLANKs if they're
664 inside a variable reference. Make this function static as it's
666 (eval): Call find_char_unquote() with IGNOREVARS set when we're
667 parsing an unexpanded line looking for semicolons.
668 Fixes Savannah bug #1454.
669 * misc.c (remove_comments): Move this to read.c and make it static
670 as it's only used there. Call find_char_unquote() with new arg.
671 * make.h: Remove prototypes for find_char_unquote() and
672 remove_comments() since they're static now.
674 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
675 its export flag and obtain its value. When we need to re-exec,
676 increment the value and add it into the environment.
677 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
678 * NEWS: Mention MAKE_RESTARTS.
679 * main.c (always_make_set): New variable. Change the -B option to
680 set this one instead.
681 (main): When checking makefiles, only set always_make_flag if
682 always_make_set is set AND the restarts flag is 0. When building
683 normal targets, set it IFF always_make_set is set.
684 (main): Avoid infinite recursion with -W, too: only set what-if
685 files to NEW before we check makefiles if we've never restarted
686 before. If we have restarted, set what-if files to NEW _after_ we
688 Fixes Savannah bug #7566:
690 2005-06-17 Paul D. Smith <psmith@gnu.org>
692 * default.c: Change VMS implicit rules to use $$$$ instead of $$
693 in the prerequisites list.
695 2005-06-12 Paul D. Smith <psmith@gnu.org>
697 Fix Savannah bug # 1328.
699 * configure.in: Check for atexit().
700 * misc.c (close_stdout): Test stdout to see if writes to it have
701 failed. If so, be sure to exit with a non-0 error code. Based on
702 code found in gnulib.
704 * main.c (main): Install close_stdout() with atexit().
706 2005-06-10 Paul D. Smith <psmith@gnu.org>
708 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
710 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
711 headers; make vmsWaitForChildren() static; extern vmsify().
712 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
713 Don't create child_execute_job() here (it's in vmsjobs.c).
714 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
716 2005-06-09 Paul D. Smith <psmith@gnu.org>
718 * variable.c (push_new_variable_scope): File variables point
719 directly to the global_setlist variable. So, inserting a new
720 scope in front of that has no effect on those variables: they
721 don't go through current_variable_set_list. If we're pushing a
722 scope and the current scope is global, push it "the other way" so
723 that the new setlist is in the global_setlist variable, and
724 next points to a new setlist with the global variable set.
725 (pop_variable_scope): Properly undo a push with the new
727 Fixes Savannah bug #11913.
729 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
731 * job.c (reap_children): Don't die of the command failed but
732 the dontcare flag is set. Fixes Savannah bug #13216.
734 * implicit.c (pattern_search): When creating a target from
735 an implicit rule match, lookup pattern target and set precious
736 flag in a newly created target. Fixes Savannah bug #13218.
738 2005-05-13 Paul D. Smith <psmith@gnu.org>
740 Implement "if... else if... endif" syntax.
742 * read.c (eval): Push all checks for conditional words ("ifeq",
743 "else", etc.) down into the conditional_line() function.
744 (conditional_line): Rework to allow "else if..." clause. New
745 return value -2 for lines which are not conditionals. The
746 ignoring flag can now also be 2, which means "already parsed a
747 true branch". If that value is seen no other branch of this
748 conditional can be considered true. In the else parsing if there
749 is extra text after the else, invoke conditional_line()
750 recursively to see if it's another conditional. If not, it's an
751 error. If so, raise the conditional value to this level instead
752 of creating a new conditional nesting level. Special check for
753 "else" and "endif", which aren't allowed on the "else" line.
754 * doc/make.texi (Conditional Syntax): Document the new syntax.
756 2005-05-09 Paul D. Smith <psmith@gnu.org>
758 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
759 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
760 recurses to the w32 directory, even on non-Windows systems. Use
761 the method suggested in the automake manual.
762 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
763 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
765 2005-05-07 Paul D. Smith <psmith@gnu.org>
767 * main.c (die): If we're dying with a fatal error (not that a
768 command has failed), write back any leftover tokens before we go.
770 * job.c (set_child_handler_action_flags): If there are jobs
771 waiting for the load to go down, set an alarm to go off in 1
772 second. This allows us to wake up from a potentially long-lasting
773 read() and start a new job if the load has gone down. Turn it off
775 (job_noop): Dummy signal handler function.
776 (new_job): Invoke it with the new semantics.
778 * docs/make.texi: Document secondary expansion. Various cleanups
781 2005-05-03 Paul D. Smith <psmith@gnu.org>
783 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
784 the targets which are to ultimately be made are called "goals";
785 see the GNU make manual. Also, MAKECMDGOALS, etc.
787 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
788 .DEFAULT_GOAL, and default_target_name to default_goal_name.
789 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
791 2005-05-02 Paul D. Smith <psmith@gnu.org>
793 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
794 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
795 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
796 functions to vmsjobs.c. #include it into jobs.c.
798 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
799 jobserver tokens. I found that this happens when an exported
800 recursive variable contains a $(shell ...) function reference: in
801 this situation we could "forget" to write back a token.
803 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
804 we have. It's not reliable to depend on the number of children in
805 our linked list so keep a separate count.
806 (new_job): Check jobserver_tokens rather than children &&
807 waiting_jobs. Increment jobserver_tokens when we get one.
808 (free_child): If jobserver_tokens is 0, internal error. If it's
809 >1, write a token back to the jobserver pipe (we don't write a
810 token for the "free" job). Decrement jobserver_tokens.
812 * main.c: Add variable master_job_slots.
813 (main): Set it to hold the number of jobs requested if we're the
814 master process, when using the jobserver.
815 (die): Sanity checks: first test jobserver_tokens to make sure
816 this process isn't holding any tokens we didn't write back.
817 Second, if master_job_slots is set count the tokens left in the
818 jobserver pipe and ensure it's the same as master_job_slots (- 1).
820 2005-04-24 Paul D. Smith <psmith@gnu.org>
822 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
823 with -l# can lose jobserver tokens, because waiting jobs are not
824 consulted properly when checking for the "free" token.
826 * job.c (free_child): Count waiting_jobs as having tokens.
827 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
828 handle jobs waiting for the load to drop.
830 2005-04-23 Paul D. Smith <psmith@gnu.org>
832 * main.c (main): Be careful to not core if a variable setting in
833 the environment doesn't contain an '='. This is illegal but can
834 happen in broken setups.
835 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
837 2005-04-12 Paul D. Smith <psmith@gnu.org>
839 The second expansion feature causes significant slowdown. Timing
840 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
841 read the makefile before the feature, to 11+s to do the same
842 operations after the feature. Additionally, memory usage
843 increased drastically. To fix this I added some intelligence that
844 avoids the overhead of the second expansion unless it's required.
846 * dep.h: Add a new boolean field, need_2nd_expansion.
848 * read.c (eval): When creating the struct dep for the target,
849 check if the name contains a "$"; if so set need_2nd_expansion to 1.
850 (record_files): If there's a "%" in a static pattern rule, it gets
851 converted to "$*" so set need_2nd_expansion to 1.
853 * file.c (expand_deps): Rework to be more efficient. Only perform
854 initialize_file_variables(), set_file_variables(), and
855 variable_expand_for_file() if the need_2nd_expansion is set.
857 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
858 (pattern_search): Ditto.
859 * main.c (handle_non_switch_argument): Ditto.
861 * read.c (read_all_makefiles): Ditto.
862 (eval_makefile): Ditto.
864 2005-04-07 Paul D. Smith <psmith@gnu.org>
866 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
867 * variable.c (sync_Path_environment): Ditto.
868 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
870 * main.c (main): Define the .FEATURES variable.
871 * NEWS: Announce .FEATURES.
872 * doc/make.texi (Special Variables): Document .FEATURES.
874 * remake.c (check_dep): If a file is .PHONY, update it even if
875 it's marked intermediate. Fixes Savannah bug #12331.
877 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
879 * file.c (expand_deps): Factor out the second expansion and
880 prerequisite line parsing logic from snap_deps().
882 * file.c (snap_deps): Use expand_deps(). Expand and parse
883 prerequisites of the .SUFFIXES special target first. Fixes
886 2005-03-13 Paul D. Smith <psmith@gnu.org>
888 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
891 2005-03-11 Paul D. Smith <psmith@gnu.org>
893 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
894 available, not undefined (from Earnie Boyd).
896 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
898 * implicit.c (pattern_search): Mark an intermediate target as
899 precious if it happened to be a prerequisite of some (other)
900 target. Fixes Savannah bug #12267.
902 2005-03-09 Paul D. Smith <psmith@gnu.org>
904 * read.c (eval_makefile): Add alloca(0).
905 (eval_buffer): Ditto.
907 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
909 * main.c (main): Use o_file instead of o_default when defining
910 the .DEFAULT_TARGET special variable.
911 * read.c (eval): Use define_variable_global() instead of
912 define_variable() when setting new value for the .DEFAULT_TARGET
913 special variable. Fixes Savannah bug #12266.
915 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
917 * imlicit.c (pattern_search): Mark files for which an implicit
918 rule has been found as targets. Fixes Savannah bug #12202.
920 2005-03-04 Paul D. Smith <psmith@gnu.org>
923 * doc/make.texi (Automatic Variables): Document $|.
925 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
927 * read.c (record_files): Instead of substituting % with
928 actual stem value in dependency list replace it with $*.
929 This fixes stem triple expansion bug.
931 * implicit.c (pattern_search): Copy stem to a separate
932 buffer and make it a properly terminated string. Assign
933 this buffer instead of STEM (which is not terminated) to
934 f->stem. Instead of substituting % with actual stem value
935 in dependency list replace it with $*. This fixes stem
936 triple expansion bug.
938 2005-03-01 Paul D. Smith <psmith@gnu.org>
940 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
941 on Windows, as it takes a handle not a pid. Just exit.
942 Fix from patch #3679, provided by Alessandro Vesely.
944 * configure.in: Update check for sys_siglist[] from autoconf manual.
945 * signame.c (strsignal): Update to use the new autoconf macro.
947 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
949 * read.c (record_files): Add a check for the list of prerequisites
950 of a static pattern rule being empty. Fixes Savannah bug #12180.
952 2005-02-28 Paul D. Smith <psmith@gnu.org>
954 * doc/make.texi (Text Functions): Update docs to allow the end
955 ordinal for $(wordlist ...) to be 0.
956 * function.c (func_wordlist): Fail if the start ordinal for
957 $(wordlist ...) is <1. Matches documentation.
958 Resolves Savannah support request #103195.
960 * remake.c (update_goal_chain): Fix logic for stopping in -q:
961 previously we were stopping when !-q, exactly the opposite. This
962 has been wrong since version 1.34, in 1994!
963 (update_file): If we got an error don't break out to run more
964 double-colon rules: just return immediately.
965 Fixes Savannah bug #7144.
967 2005-02-27 Paul D. Smith <psmith@gnu.org>
969 * misc.c (end_of_token): Make argument const.
970 * make.h: Update prototype.
972 * function.c (abspath, func_realpath, func_abspath): Use
973 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
974 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
975 * read.c (record_files): Ditto.
976 * variable.c (do_variable_definition): Ditto.
978 * function.c (func_error): Create a new function $(info ...) that
979 simply prints the message to stdout with no extras.
980 (function_table_init): Add new function to the table.
981 * NEWS: Add $(info ...) reference.
982 * doc/make.texi (Make Control Functions): Document it.
984 New feature: if the system supports symbolic links, and the user
985 provides the -L/--check-symlink-time flag, then use the latest
986 mtime between the symlink(s) and the target file.
988 * configure.in (MAKE_SYMLINKS): Check for lstat() and
989 readlink(). If both are available, define MAKE_SYMLINKS.
990 * main.c: New variable: check_symlink_flag.
991 (usage): Add a line for -L/--check-symlink-times to the help string.
992 (switches): Add -L/--check-symlink-times command line argument.
993 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
994 print a warning and disable it again.
995 * make.h: Declare check_symlink_flag.
996 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
997 if the file is a symlink then check each link in the chain and
998 choose the NEWEST mtime we find as the mtime for the file. The
999 newest mtime might be the file itself!
1000 * NEWS: Add information about this new feature.
1001 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1003 Avoid core dumps described in Savannah bug # 12124:
1005 * file.c: New variable snapped_deps remember whether we've run
1007 (snap_deps): Set it.
1008 * filedef.h: Extern it.
1009 * read.c (record_files): Check snapped_deps; if it's set then
1010 we're trying to eval a new target/prerequisite relationship from
1011 within a command script, which we don't support. Fatal.
1013 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1015 Implementation of the .DEFAULT_TARGET special variable.
1017 * read.c (eval): If necessary, update default_target_name when
1019 * read.c (record_files): Update default_target_file if
1020 default_target_name has changed.
1021 * main.c (default_target_name): Define.
1022 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1023 default_target_name is set use default_target_file as a root
1025 * filedef.h (default_target_name): Declare.
1026 * dep.h (free_dep_chain):
1027 * misc.c (free_dep_chain): Change to operate on struct nameseq
1028 and change name to free_ns_chain.
1029 * file.c (snap_deps): Update to use free_ns_chain.
1031 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1033 Implementation of the second expansion in explicit rules,
1034 static pattern rules and implicit rules.
1036 * read.c (eval): Refrain from chopping up rule's dependencies.
1037 Store them in a struct dep as a single dependency line. Remove
1038 the code that implements SySV-style automatic variables.
1040 * read.c (record_files): Adjust the code that handles static
1041 pattern rules to expand all percents instead of only the first
1042 one. Reverse the order in which dependencies are stored so that
1043 when the second expansion reverses them again they appear in
1044 the makefile order (with some exceptions, see comments in
1045 the code). Remove the code that implements SySV-style automatic
1048 * file.c (snap_deps): Implement the second expansion and chopping
1049 of dependency lines for explicit rules.
1051 * implicit.c (struct idep): Define an auxiliary data type to hold
1052 implicit rule's dependencies after stem substitution and
1055 * implicit.c (free_idep_chain): Implement.
1057 * implicit.c (get_next_word): Implement helper function for
1058 parsing implicit rule's dependency lines into words taking
1059 into account variable expansion requests. Used in the stem
1062 * implicit.c (pattern_search): Implement the second expansion
1063 for implicit rules. Also fixes bug #12091.
1065 * commands.h (set_file_variables): Declare.
1066 * commands.c (set_file_variables): Remove static specifier.
1068 * dep.h (free_dep_chain): Declare.
1069 * misc.c (free_dep_chain): Implement.
1071 * variable.h (variable_expand_for_file): Declare.
1072 * expand.c (variable_expand_for_file): Remove static specifier.
1074 * make.h (strip_whitespace): Declare.
1075 * function.c (strip_whitespace): Remove static specifier.
1077 2005-02-26 Paul D. Smith <psmith@gnu.org>
1079 * main.c (main): Check for ferror() when reading makefiles from stdin.
1080 Apparently some shells in Windows don't close pipes properly and
1083 2005-02-24 Jonathan Grant <jg@jguk.org>
1085 * configure.in: Add MinGW configuration options, and extra w32 code
1087 * Makefile.am: Add MinGW configuration options, and extra w32 code
1089 * main.c: Determine correct program string (after last \ without .exe).
1090 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1092 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1093 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1094 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1095 environment support.
1097 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1099 * function.c (func_shell): When initializing error_prefix, check
1100 that reading file name is not null. This fixes long-standing
1101 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1103 2005-02-09 Paul D. Smith <psmith@gnu.org>
1105 * maintMakefile: Update the CVS download URL to simplify them.
1106 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1107 downloading the .texi files from Savannah now.
1109 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1111 * main.c (handle_non_switch_argument): Only add variables to
1112 command_variables if they're not already there: duplicate settings
1113 waste space and can be confusing to read.
1115 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1116 this header is never included by non-WINDOWS32 code, and it
1117 requires <config.h> to define which isn't always included first.
1119 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1120 testing MINGW32 versions.
1122 * main.c (log_working_directory): flush stdout to be sure the WD
1123 change is printed before any stderr messages show up.
1125 2005-02-01 Paul D. Smith <psmith@gnu.org>
1127 * maintMakefile (po_repo): Update the GNU translation site URL.
1129 2004-12-01 Paul D. Smith <psmith@gnu.org>
1131 * main.c (main): Change char* env_shell to struct variable shell_var.
1132 * variable.c (target_environment): Use new shell_var.
1134 2004-11-30 Paul D. Smith <psmith@gnu.org>
1136 * configure.in: The old way we avoided creating build.sh from
1137 build.sh.in before build.sh.in exists doesn't work anymore; we
1138 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1139 the help!). This also keeps automake from complaining.
1140 * Makefile.am (README): Add a dummy target so automake won't
1141 complain that this file doesn't exist when we checkout from CVS.
1142 * maintMakefile (.dep_segment): Rewrite this rule since newer
1143 versions of automake don't provide DEP_FILES.
1145 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1147 Implementation of `realpath' and `abspath' built-in functions.
1149 * configure.in: Check for realpath.
1150 * function.c (abspath): Return an absolute file name that does
1151 not contain any `.' or `..' components, nor repeated `/'.
1152 * function.c (func_abspath): For each name call abspath.
1153 * function.c (func_realpath): For each name call realpath
1154 from libc or delegate to abspath if realpath is not available.
1155 * doc/make.texi (Functions for File Names): Document new functions.
1156 * doc/make.texi (Quick Reference): Ditto.
1158 2004-11-28 Paul D. Smith <psmith@gnu.org>
1160 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1161 arguments. Fixes bug #10252.
1163 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1165 * main.c (main): Set SHELL to v_noexport by default. Remember the
1166 original environment setting of SHELL in the env_shell variable.
1167 * main.h: Export new env_shell variable.
1168 * variable.c (target_environment): If we find a v_noexport
1169 variable for SHELL, add a SHELL variable with the env_shell value.
1170 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1171 * doc/make.texi (Variables/Recursion): Ditto.
1173 2004-11-28 Paul D. Smith <psmith@gnu.org>
1175 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1176 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1177 Patch by Alessandro Vesely.
1179 2004-11-12 Paul D. Smith <psmith@gnu.org>
1181 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1182 the command line if it's inside a string.
1183 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1185 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1187 * function.c (func_lastword): New function: return last word
1188 from the list of words.
1189 * doc/make.texi: Document $(lastword ). Fix broken links in
1190 Quick Reference section.
1192 2004-10-06 Paul D. Smith <psmith@gnu.org>
1194 Apply patch from Alessandro Vesely, provided with bug # 9748.
1195 Fix use of tmpnam() to work with Borland C.
1197 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1198 construction of a temporary filename, and call new function
1199 create_batch_filename().
1200 (create_batch_filename) [WINDOWS32]: New function to create a
1203 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1205 * read.c (record_target_var): Expand simple pattern-specific
1207 * variable.c (initialize_file_variables): Do not expand simple
1208 pattern-specific variable.
1210 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1212 * remake.c (update_file_1): When rebuilding makefiles inherit
1213 dontcare flag from a target that triggered update.
1215 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1217 * variable.c (initialize_file_variables): Mark pattern-specific
1218 variable as a per-target and copy export status.
1220 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1222 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1224 * implicit.c (pattern_search): When considering an implicit rule's
1225 prerequisite check that it is actually a target rather then
1226 just an entry in the file hashtable.
1228 2004-09-21 Paul D. Smith <psmith@gnu.org>
1230 * read.c (readstring): Fix some logic errors in backslash handling.
1231 (eval): Remove some unnecessary processing in buffer handling.
1232 (record_target_var): Assert that parse_variable_definition() succeeded.
1233 Reported by: Markus Mauhart <qwe123@chello.at>.
1235 * misc.c: Removed the sindex() function. All instances of this
1236 function were trivially replaceable by the standard strstr()
1237 function, and that function will always have better (or certainly
1238 no worse) performance than the very simple-minded algorithm
1239 sindex() used. This can matter with complex makefiles.
1240 * make.h: Remove the prototype for sindex().
1241 * function.c (subst_expand): Convert sindex() call to strstr().
1242 This means we no longer need to track the TLEN value so remove that.
1243 (func_findstring): Convert sindex() to strstr().
1244 * commands.c (chop_commands): Convert sindex() calls to strstr().
1245 Suggested by: Markus Mauhart <qwe123@chello.at>.
1247 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1248 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1249 If SHELL is set to CMD.EXE then assume it's batch-mode and
1250 non-unixy. I wrote the code differently from the patch, though,
1251 to make it safer. This also resolves bug #9174.
1253 2004-09-20 Paul D. Smith <psmith@gnu.org>
1255 * expand.c (variable_expand_string): Modify to invoke
1256 patsubst_expand() instead of subst_expand(); the latter didn't
1257 handle suffix patterns correctly.
1258 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1259 was used only from variable_expand_string() and is no longer used
1261 (func_subst): Ditto, on call to subst_expand().
1262 (patsubst_expand): Require the percent pointers to point to the
1263 character after the %, not to the % itself.
1264 * read.c (record_files): New call criteria for patsubst_expand().
1265 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1266 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1268 2004-09-19 Paul D. Smith <psmith@gnu.org>
1270 * function.c (subst_expand): Fix a check in by_word: look for a
1271 previous blank if we're beyond the beginning of the string, not
1272 the beginning of the word.
1273 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1275 2004-05-16 Paul D. Smith <psmith@gnu.org>
1277 * remake.c (update_goal_chain): Change the argument specifying
1278 whether we're rebuilding makefiles to be a global variable,
1279 REBUILDING_MAKEFILES.
1280 (complain): Extract the code that complains about no rules to make
1281 a target into a separate function.
1282 (update_file_1): If we tried to rebuild a file during the makefile
1283 rebuild phase and it was dontcare, then no message was printed.
1284 If we then try to build the same file during the normal build,
1285 print a message this time.
1286 (remake_file): Don't complain about un-remake-able files when
1287 we're rebuilding makefiles.
1289 2004-05-11 Paul D. Smith <psmith@gnu.org>
1291 * job.c (construct_command_argv_internal): OS/2 patches from
1292 Andreas Buening <andreas.buening@nexgo.de>.
1294 2004-05-10 Paul D. Smith <psmith@gnu.org>
1296 * remake.c (update_file): Don't walk the double-colon chain unless
1297 this is a double-colon rule. Fix suggested by Boris Kolpackov
1298 <boris@kolpackov.net>.
1300 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1301 * readme.vms: New section describing OpenVMS support and issues.
1302 * default.c (default_variables): Add support for IA64.
1303 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1304 without some privilege aborts make with the error
1305 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1306 pressing Ctrl+Y and the input device is no terminal. The change
1307 catches this error and just continues.
1309 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1311 2004-04-25 Paul D. Smith <psmith@gnu.org>
1313 * commands.c (set_file_variables): Set $< properly in the face of
1314 order-only prerequisites.
1315 Patch from Boris Kolpackov <boris@kolpackov.net>
1317 2004-04-21 Bob Byrnes <byrnes@curl.com>
1319 * main.c (main): Notice failures to remake makefiles.
1321 2004-03-28 Paul D. Smith <psmith@gnu.org>
1323 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1325 * job.c: No default shell for RISC OS.
1326 (load_too_high): Hard-code the return to 1.
1327 (construct_command_argv_internal): No sh_chars or sh_cmds.
1328 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1330 2004-03-20 Paul D. Smith <psmith@gnu.org>
1332 * variable.c (do_variable_definition): Don't append from the
1333 global set if a previous non-appending target-specific variable
1334 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1337 * expand.c (reference_variable): Don't give up on variables with
1338 no value that have the target-specific append flag set: they might
1339 have a value after all. Reported by Oliver Schmidt
1340 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1341 <nikulin@dx1cmd.inp.nsk.su>.
1343 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1344 refer to absolute pathnames in directories that don't exist: some
1345 portion of the makefile could create those directories before we
1346 match the pattern. Fixes bugs #775 and #108.
1348 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1350 * main.c (main): Free makefile_mtimes if we have any.
1351 * README.W32.template: Update documentation for the current status
1352 of the MS-Windows port.
1353 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1354 environment variable is sometimes already defined which causes the
1356 * main.c (debug_signal_handler): Only define this function if
1357 SIGUSR1 is available.
1359 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1361 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1362 * README.OS2.template: Documentation updates.
1363 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1364 link line for safety.
1365 * maintMakefile (build.sh.in): Remove an extraneous ")".
1366 * job.c (child_execute_job): Close saved FDs.
1367 * job.c (exec_command) [OS/2]: exec_command(): If the command
1368 can't be exec'ed and if the shell is not Unix-sh, then try again
1369 with argv = { "cmd", "/c", ... }. Normally, this code is never
1370 reached for the cmd shell unless the command really doesn't exist.
1371 (construct_command_argv_internal) [OS/2]: The code for cmd
1372 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1373 The CMD builtin commands are case insensitive so use strcasecmp().
1375 2004-03-19 Paul D. Smith <psmith@gnu.org>
1377 * read.c (do_define): Re-order line counter increment so the count
1378 is accurate (we were losing one line per define). Reported by
1379 Dave Yost <Dave@Yost.com>.
1381 2004-03-06 Paul D. Smith <psmith@gnu.org>
1383 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1385 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1386 * misc.c (message,error,fatal): Ditto.
1387 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1388 * config.h.W32.template: Ditto.
1389 * config.h-vms.template: Ditto.
1390 * config.ami.template: Ditto.
1392 2004-03-04 Paul D. Smith <psmith@gnu.org>
1394 * README.template: Add a note about broken /bin/sh on SunOS
1395 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1397 * misc.c (message, error, fatal): Don't use "..." if we're using
1398 varargs. ansi2knr should handle this but it doesn't work: it
1399 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1400 done. On many systems (SunOS for example) va_dcl is a #define.
1401 So, force the use of the non-"..." version on pre-ANSI compilers.
1403 * maintMakefile (sign-dist): Create some rules to help automate
1404 the new GNU ftp upload method.
1406 2004-02-24 Paul D. Smith <psmith@gnu.org>
1408 * config.h.W32.template: Add HAVE_STDARG_H
1409 * config.h-vms.template: Ditto.
1410 * config.ami.template: Ditto.
1412 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1414 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1415 * build_w32.bat: Remove extra "+".
1417 2004-02-23 Paul D. Smith <psmith@gnu.org>
1419 * make.h: Create an UNUSED macro to mark unused parameters.
1420 * (many): Clean up warnings by applying UNUSED, fixing
1421 signed/unsigned incompatibilities, etc.
1423 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1425 * filedef.h: Name the command_state enumeration.
1426 * file.c (set_command_state): Use the enumeration in the function
1429 * configure.in: Explicitly set SET_MAKE to empty, to disable
1430 MAKE=make even when no make already exists. Fix bug #3823.
1432 2004-02-22 Paul D. Smith <psmith@gnu.org>
1434 * maintMakefile: Perl script to clean up all non-CVS files. Use
1435 it on all the subdirectories for the cvs-clean target.
1437 * main.c (decode_switches): Require non-empty strings for all our
1438 string command-line options. Fixes Debian bug # 164165.
1440 * configure.in: Check for stdarg.h and varargs.h.
1441 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1442 for printing messages.
1443 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1448 A number of patches for OS/2 support from Andreas Buening
1449 <andreas.buening@nexgo.de>:
1451 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1452 disable the SIGCHLD handler.
1453 (reap_children) [OS/2]: Remove special handling of job_rfd.
1454 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1455 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1456 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1457 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1458 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1461 2004-02-21 Paul D. Smith <psmith@gnu.org>
1463 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1464 <mail@kristov.de> reports that if process_begin() fails we don't
1465 handle the error condition correctly in all cases.
1466 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1467 to have a newline on the message.
1469 * job.c (construct_command_argv_internal): Add "test" to UNIX
1470 sh_cmds[]. Fixes Savannah bug # 7606.
1472 2004-02-04 Paul D. Smith <psmith@gnu.org>
1474 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1475 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1476 Hartmut Becker <Hartmut.Becker@hp.com>.
1478 2004-01-21 Paul D. Smith <psmith@gnu.org>
1480 * job.c (load_too_high): Implement an algorithm to control the
1481 "thundering herd" problem when using -l to control job creation
1482 via the load average. The system only recomputes the load once a
1483 second but we can start many jobs in a second. To solve this we
1484 keep track of the number of jobs started in the last second and
1485 apply a weight to try to guess what a correct load would be.
1486 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1487 Also fixes bug #4693.
1488 (reap_children): Decrease the job count for this second.
1489 (start_job_command): Increase the job count for this second.
1491 * read.c (conditional_line): Expand the text after ifn?def before
1492 checking to see if it's a single word. Fixes bug #7257.
1494 2004-01-09 Paul D. Smith <psmith@gnu.org>
1496 * file.c (print_file): Recurse to print all targets in
1497 double-colon rules. Fixes bug #4518, reported (with patch) by
1498 Andrew Chatham <chatham@google.com>.
1500 2004-01-07 Paul D. Smith <psmith@gnu.org>
1502 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1503 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1504 AC_FUNC_SETVBUF_REVERSED.
1506 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1507 (MAKE Variable): Fix Savannah bug #4898.
1509 * job.c (construct_command_argv_internal): Add "!" to the list of
1510 shell escape chars. POSIX sh allows it to appear before a
1511 command, to negate the exit code. Fixes bug #6404.
1513 * implicit.c (pattern_search): When matching an implicit rule,
1514 remember which dependencies have the ignore_mtime flag set.
1515 Original fix provided in Savannah patch #2349, by Benoit
1516 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1518 2003-11-22 Paul D. Smith <psmith@gnu.org>
1520 * README.W32.template (Outputs): Clarification on -j with
1521 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1524 2003-11-02 Paul D. Smith <psmith@gnu.org>
1526 * function.c (func_if): Strip all the trailing whitespace from the
1527 condition, then don't expand it. Fixed bug # 5798.
1529 * expand.c (recursively_expand_for_file): If we're expanding a
1530 variable with no file context, then use the variable's context.
1533 2003-10-21 Paul D. Smith <psmith@gnu.org>
1535 * main.c (log_working_directory): Add newlines to printf()s.
1537 * README.cvs: Add a note to ignore warnings during autoreconf.
1539 * maintMakefile (po_repo): Set a new URL for PO file updates.
1540 (get-config/config.guess get-config/config.sub): Get these files
1541 from the Savannah config project instead of ftp.gnu.org.
1543 2003-10-05 Paul Eggert <eggert@twinsun.com>
1545 * main.c (main): Avoid potential subscript error if environ has
1548 2003-08-22 Paul D. Smith <psmith@gnu.org>
1550 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1551 systems which don't yet implement the C89 standard :-/.
1553 2003-07-18 Paul D. Smith <psmith@gnu.org>
1555 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1556 [WINDOWS32]: Initialize hash.
1558 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1560 * dir.c (read_dirstream): Provide a workaround for broken versions of
1561 the MinGW dirent structure.
1563 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1565 * w32/include/dirent.h: Add __MINGW32__ filter.
1567 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1569 * make.h: Add global declaration of *make_host.
1570 * main.c (print_usage): Remove local declaration of *make_host.
1571 (print_version): Display "This program built for ..." after Copyright
1574 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1576 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1577 execution of "makeinfo --html make.texi".
1579 2003-04-30 Paul D. Smith <psmith@gnu.org>
1581 * build.template: Make some changes to maybe allow this script to
1582 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1584 * README.OS2.template: New file for OS/2 support. Original
1585 contributed by Andreas Buening.
1586 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1589 2003-04-19 Paul D. Smith <psmith@gnu.org>
1591 Fix bug #1405: allow a target to match multiple pattern-specific
1594 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1595 variable.c, where they've always belonged.
1596 * rule.h: Move the prototypes and struct pattern_var as well.
1597 * variable.c (initialize_file_variables): Invoke
1598 lookup_pattern_var() in a loop, until no more matches are found.
1599 If a match is found, create a new variable set for the target's
1600 pattern variables. Then merge the contents of each matching
1601 pattern variable set into the target's pattern variable set.
1602 (lookup_pattern_var): Change this function to be usable
1603 in a loop. It takes a starting position: if NULL, start at the
1604 beginning; if non-NULL, start with the pattern variable after that
1605 position, and return the next matching pattern.
1606 (create_pattern_var): Create a unique instance of
1607 pattern-specific variables for every definition in the makefile.
1608 Don't combine the same pattern together. This allows us to
1609 process the variable handling properly even when the same pattern
1610 is used multiple times.
1611 (parse_variable_definition): New function: break out the parsing
1612 of a variable definition line from try_variable_definition.
1613 (try_variable_definition): Call parse_variable_definition to
1615 (print_variable_data_base): Print out pattern-specific variables.
1616 * variable.h (struct variable): Remember when a variable is
1617 conditional. Also remember its flavor.
1618 (struct pattern_var): Instead of keeping a variable set, we just
1619 keep a single variable for each pattern.
1620 * read.c (record_target_var): Each pattern variable contains only a
1621 single variable, not a set, so create it properly.
1622 * doc/make.texi (Pattern-specific): Document the new behavior.
1624 2003-04-17 Paul D. Smith <psmith@gnu.org>
1626 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1627 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1628 file/directory naming rules for VMS so I can't tell whether this
1631 2003-04-09 Paul D. Smith <psmith@gnu.org>
1633 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1634 DOS-style pathnames: backslash separators and drive specifiers.
1636 2003-03-28 Paul D. Smith <psmith@gnu.org>
1638 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1639 the intermediate flag on all targets. Fixes bug #2515.
1641 2003-03-24 Paul D. Smith <psmith@gnu.org>
1643 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1644 Upgrade to autoconf 2.57 and automake 1.7.3.
1646 * job.c: More OS/2 changes from Andreas Buening.
1648 * file.c (print_file): Fix variable initialization.
1651 * remake.c (notice_finished_file):
1653 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1654 some calls (like readdir()) return NULL in valid situations
1655 without resetting errno. Fixes bug #2846.
1657 2003-02-25 Paul D. Smith <psmith@gnu.org>
1659 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1661 * job.c (_is_unixy_shell) [OS/2]: New function.
1662 Set default shell to /bin/sh.
1663 (reap_children): Close the job_rfd pipe here since we don't use a
1665 (set_child_handler_action_flags): define this to empty on OS/2.
1666 (start_job_command): Close the jobserver pipe and use
1667 child_execute_job() instead of fork/exec.
1668 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1669 rather than exec'ing, then reconfigure stdin/stdout.
1670 (exec_command): Rewrite to use spawn instead of exec. Return the
1673 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1674 in DOS. Handle the TEMP environment variable as in DOS. Don't
1675 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1676 use -j in DOS mode. Use child_execute_job() instead of
1679 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1682 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1683 prototypes that return values.
1685 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1687 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1688 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1690 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1693 2003-02-24 Paul D. Smith <psmith@gnu.org>
1695 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1696 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1697 (child_execute_job) [VMS]: Handle error status properly.
1698 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1700 * function.c (func_shell): Use EINTRLOOP() while reading from the
1701 subshell pipe (Fixes bug #2502).
1702 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1704 * main.c (main): Ditto.
1706 2003-01-30 Paul D. Smith <psmith@gnu.org>
1708 * read.c (eval): eval() was not fully reentrant, because the
1709 collapsed buffer was static. Change it to be an automatic
1710 variable so that eval() can be invoked recursively.
1712 (eval): Apply patch # 1022: fix memory reference error on long
1713 target-specific variable lines.
1714 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1716 * function.c (check_numeric): Combine the is_numeric() function
1717 into this function, since it's only called from one place.
1718 Constify this function. Have it print the incorrect string in the
1719 error message. Fixes bug #2407.
1720 (strip_whitespace): Constify.
1721 (func_if): Constify.
1722 * expand.c (expand_argument): Constify.
1724 2003-01-29 Paul D. Smith <psmith@gnu.org>
1726 Fix bug # 2169, also reported by other people on various systems.
1728 * make.h: Some systems, such as Solaris and PTX, do not fully
1729 implement POSIX-compliant SA_RESTART functionality; important
1730 system calls like stat() and readdir() can still fail with EINTR
1731 even if SA_RESTART has been set on the signal handler. So,
1732 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1733 EINTR for system calls which return -1 or 0 (NULL), respectively,
1735 Also, remove the old atomic_stat()/atomic_readdir() and
1736 HAVE_BROKEN_RESTART handling.
1738 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1740 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1741 * remake.c (touch_file): Ditto.
1743 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1744 * read.c (construct_include_path): Ditto.
1745 * remake.c (name_mtime): Ditto.
1746 * vpath.c (selective_vpath_search): Ditto.
1747 * dir.c (find_directory): Ditto.
1748 (local_stat): Ditto.
1749 (find_directory): Use ENULLLOOP() to wrap opendir().
1750 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1752 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1753 atomic_readdir() handling.
1755 2003-01-22 Paul D. Smith <psmith@gnu.org>
1757 * function.c (func_call): Fix Bug #1744. If we're inside a
1758 recursive invocation of $(call ...), mask any of the outer
1759 invocation's arguments that aren't used by this one, so that this
1760 invocation doesn't "inherit" them accidentally.
1762 2002-12-05 Paul D. Smith <psmith@gnu.org>
1764 * function.c (subst_expand): Valery Khamenia reported a
1765 pathological performance hit when doing substitutions on very
1766 large values with lots of words: turns out we were invoking
1767 strlen() a ridiculous number of times. Instead of having each
1768 call to sindex() call strlen() again, keep track of how much of
1769 the text we've seen and pass the length to sindex().
1771 2002-11-19 Paul D. Smith <psmith@gnu.org>
1773 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1776 2002-11-16 Paul D. Smith <psmith@gnu.org>
1778 * NMakefile.template (OBJS): Add hash.c object file.
1779 * SMakefile.template (srcs): Ditto.
1780 * Makefile.ami (objs): Ditto.
1781 * build_w32.bat: Ditto.
1783 * Makefile.DOS.template: Remove extra dependencies.
1785 2002-10-25 Paul D. Smith <psmith@gnu.org>
1787 * expand.c (install_variable_buffer): New function. Install a new
1788 variable_buffer context and return the previous one.
1789 (restore_variable_buffer): New function. Free the current
1790 variable_buffer context and put a previously saved one back.
1791 * variable.h: Prototypes for {install,restore}_variable_buffer.
1792 * function.c (func_eval): Push a new variable_buffer context
1793 before we eval, then restore the old one when we're done.
1796 * read.c (install_conditionals): New function. Install a new
1797 conditional context and return the previous one.
1798 (restore_conditionals): New function. Free the current
1799 conditional context and put a previously saved one back.
1800 (eval): Use the {install,restore}_conditionals for "include"
1802 (eval_buffer): Use {install,restore}_conditionals to preserve the
1803 present conditional state before we evaluate the buffer.
1806 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1808 (Recursion): Add a variable index entry for CURDIR.
1810 * README.cvs: Update to appropriate versions.
1811 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1812 don't need to copy loadavg.c: automake is smart enough to create
1813 it for me. Still have a bug in automake related to ansi2knr tho.
1815 2002-10-14 Paul D. Smith <psmith@gnu.org>
1817 * remake.c (notice_finished_file): Only touch targets if they have
1818 at least one command (as per POSIX). Resolve Bug #1418.
1820 * *.c: Convert to using ANSI C-style function definitions.
1821 * Makefile.am: Enable the ansi2knr feature of automake.
1822 * configure.in: ditto.
1824 2002-10-13 Paul D. Smith <psmith@gnu.org>
1826 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1827 for automatic variable values like $^, etc. In the case of very
1828 large lists of prerequisites this causes problems. Instead reuse
1829 a static buffer (resizeable) for each variable.
1831 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1832 target-specific variable definitions. Check for it and set an
1834 (record_target_var): Set the export field to v_export if the
1835 "exported" flag is set.
1836 * doc/make.texi (Target-specific): Document the ability to use
1839 * doc/make.texi: Change the name of the section on automatic
1840 variables from "Automatic" to "Automatic Variables". Added text
1841 clarifying the scope of automatic variables.
1843 2002-10-04 Paul D. Smith <psmith@gnu.org>
1845 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1847 (record_files): Ditto.
1849 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1850 the search for the '=' to only within the enclosing parens.
1852 2002-10-03 Paul D. Smith <psmith@gnu.org>
1854 Version 3.80 released.
1856 * dir.c: Change hash functions to use K&R function definition style.
1857 * function.c: Ditto.
1859 * variable.c: Ditto.
1861 Update to automake 1.7.
1863 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1864 (pdf): Remove this target as automake now provides one.
1866 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1868 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1870 * makefile.com: Updates for GNU make 3.80.
1871 * makefile.vms: Ditto.
1873 2002-09-23 Paul D. Smith <psmith@gnu.org>
1875 * read.c (enum make_word_type): Remove w_comment.
1876 (get_next_mword): Don't treat comment characters as special; where
1877 this function is used we will never see a comment (it's stripped
1878 before we get here) and treating comments specially means that
1879 targets like "foo\#bar" aren't handled properly.
1881 2002-09-18 Paul D. Smith <psmith@gnu.org>
1883 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1885 * read.c (eval): Expansion of arguments to export/unexport was
1886 ignoring all arguments after the first one. Change the algorithm
1887 to expand the whole line once, then parse the results.
1889 2002-09-17 Paul D. Smith <psmith@gnu.org>
1891 Fix Bug #940 (plus another bug I found while looking at this):
1893 * read.c (record_target_var): enter_file() will add a new entry if
1894 it's a double-colon target: we don't want to do that in this
1895 situation. Invoke lookup_file() and only enter_file() if it does
1896 not already exist. If the file we get back is a double-colon then
1897 add this variable to the "root" double-colon target.
1899 * variable.c (initialize_file_variables): If this file is a
1900 double-colon target but is not the "root" target, then initialize
1901 the root and make the root's variable list the parent of our
1904 2002-09-13 Paul D. Smith <psmith@gnu.org>
1906 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1908 * hash.c (round_up_2): Get rid of a warning.
1910 2002-09-12 Paul D. Smith <psmith@gnu.org>
1912 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1913 so it doesn't complain about getloadavg.c.
1915 * commands.c (set_file_variables): Make sure we always alloca() at
1916 least 1 character for the value of $? (for '\0').
1918 2002-09-11 Paul D. Smith <psmith@gnu.org>
1920 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1921 macro to use RESULT instead of the incorrect _RESULT_.
1923 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1924 and atomic_readdir(). We need to #include dirent.h to get this to
1926 * misc.c (atomic_readdir): Fix typos.
1928 2002-09-10 Paul D. Smith <psmith@gnu.org>
1930 * read.c (eval): Expand variable lists given to export and
1931 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1932 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1934 * doc/make.texi (Variables/Recursion): Document this.
1935 (Conditional Syntax): And here.
1937 2002-09-09 Paul D. Smith <psmith@gnu.org>
1939 * configure.in: Check for memmove().
1941 2002-09-07 Paul D. Smith <psmith@gnu.org>
1943 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1944 Michael Sterrett <msterret@coat.com> reports that while it has
1945 SA_RESTART, it does not work properly.
1947 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1948 that invokes stat() and loops to do it again if it returns EINTR.
1949 (atomic_readdir): Ditto, with readdir().
1951 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1952 and readdir() to atomic_stat() and atomic_readdir().
1954 2002-09-04 Paul D. Smith <psmith@gnu.org>
1956 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
1957 reports that GNU make sometimes doesn't recognize that targets can
1958 be made, when directories can be created as prerequisites. He
1959 reports that changing the order of predicates in the DEP->changed
1960 flag test so that lookup_file() is always performed, solves this
1963 2002-08-08 Paul D. Smith <psmith@gnu.org>
1965 * configure.in: Require a newer version of gettext.
1967 * misc.c (perror_with_name): Translate the format string (for
1968 right-to-left language support).
1969 (pfatal_with_name): Ditto.
1971 * main.c: Create a static array of strings to store the usage
1972 text. This is done to facilitate translations.
1973 (struct command_switch): Remove argdesc and description fields.
1974 (switches): Remove values for obsolete fields.
1975 (print_usage): Print each element of the usage array.
1977 * hash.c: Change function definitions to be K&R style.
1979 2002-08-02 Paul D. Smith <psmith@gnu.org>
1981 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
1982 this one because it's too hard to get right. We'll look at it for
1984 * main.c (main): Don't create the .TARGETS variable.
1985 * variable.c (handle_special_var): Don't handle .TARGETS.
1987 2002-08-01 Paul D. Smith <psmith@gnu.org>
1989 * main.c (switches): Add a new option, -B (--always-make). If
1990 specified, make will rebuild all targets that it encounters even
1991 if they don't appear to be out of date.
1992 (always_make_flag): New flag.
1993 * make.h: Extern always_make_flag.
1994 * remake.c (update_file_1): Check always_make_flag; if it's set we
1995 will always rebuild any target we can, even if none of its
1996 prerequisites are newer.
1999 * doc/make.texi (Shell Function): Make it clear that make
2000 variables marked as "export" are not passed to instances of the
2003 Add new introspection variable .VARIABLES and .TARGETS.
2005 * variable.c (handle_special_var): New function. If the variable
2006 reference passed in is "special" (.VARIABLES or .TARGETS),
2007 calculate the new value if necessary. .VARIABLES is handled here:
2008 walk through the hash of defined variables and construct a value
2009 which is a list of the names. .TARGETS is handled by
2010 build_target_list().
2011 (lookup_variable): Invoke handle_special_var().
2012 * file.c (build_target_list): Walk through the hask of known files
2013 and construct a list of the names of all the ones marked as
2015 * main.c (main): Initialize them to empty (and as simple variables).
2016 * doc/make.texi (Special Variables): Document them.
2017 * NEWS: Mention them.
2019 * variable.h (struct variable): Add a new flag "exportable" which
2020 is true if the variable name is valid for export.
2021 * variable.c (define_variable_in_set): Set "exportable" when a new
2022 variable is defined.
2023 (target_environment): Use the "exportable" flag instead of
2024 re-checking the name here... an efficiency improvement.
2026 2002-07-31 Paul D. Smith <psmith@gnu.org>
2028 * config.h-vms.template: Updates to build on VMS. Thanks to
2029 Brian_Benning@aksteel.com for helping verify the build.
2030 * makefile.com: Build the new hash.c file.
2031 * hash.h: Use strcpmi(), not stricmp(), in the
2032 HAVE_CASE_INSENSITIVE_FS case.
2034 2002-07-30 Paul D. Smith <psmith@gnu.org>
2036 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2037 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2038 Reported by <Brian_Benning@aksteel.com>.
2040 2002-07-10 Paul D. Smith <psmith@gnu.org>
2042 * variable.c (pop_variable_scope): Remove variable made unused by
2043 new hash infrastructure.
2044 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2045 comparisons as well as name comparisons.
2046 * variable.h: Add a prototype for new hash_init_function_table().
2047 * file.c (lookup_file): Remove variables made unused by new hash
2049 * dir.c (directory_contents_hash_2): Missing return of hash value.
2050 (dir_contents_file_exists_p): Remove variables made unused by new
2051 hash infrastructure.
2054 Installed Greg McGary's integration of the hash functions from the
2055 GNU id-utils package:
2057 2002-07-10 Greg McGary <greg@mcgary.org>
2059 * scripts/functions/filter-out: Add literals to to the
2060 pattern space in order to add complexity, and trigger
2061 use of an internal hash table. Fix documentation strings.
2062 * scripts/targets/INTERMEDIATE: Reverse order of files
2063 passed to expected `rm' command.
2065 2002-07-10 Greg McGary <greg@mcgary.org>
2067 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
2068 * hash.c: New file, taken from id-utils.
2069 * hash.h: New file, taken from id-utils.
2071 * make.h (HASH, HASHI): Remove macros.

2082 * main.c (initialize_global_hash_tables): New function.
2083 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
2084 * misc.c (remove_comments): Pass char constants to find_char_unquote.
2085 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
2087 * dir.c (hash.h): New #include.
2088 (struct directory_contents) [next, files]: Remove members.
2089 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.
2090 (directory_contents_hash_1, directory_contents_hash_2,
2091 directory_contents_hash_cmp): New functions.
2092 (directories_contents): Change type to `struct hash_table'.
2093 (struct directory) [next]: Remove member.
2094 (directory_hash_1, directory_hash_2, directory_hash_cmp): New funcs.

2123 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
2124 (struct a_pattern): New struct.
2125 (func_filter_filterout): Pass through patterns noting boundaries
2126 and '%', if present. Note a_word length. Use a hash table if
2127 arglists are large enough to justify cost.
2128 (function_table_init): Renamed from function_table.
2129 (function_table): Declare as `struct hash_table'.
2130 (FUNCTION_TABLE_ENTRIES): New constant.

2135 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
2136 (uniquize_deps): Use hash table to efficiently identify duplicates.
2137 (find_char_unquote): Accept two char-constant stop chars, rather
2138 than a string constant, avoiding zillions of calls to strchr.
2139 Tighten inner search loops to test only for desired delimiters.
2141 * variable.c (variable_hash_1, variable_hash_2,
2142 variable_hash_cmp): New functions.

2157 2002-07-10 Paul D. Smith <psmith@gnu.org>
2159 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2160 prerequisite list. A real SysV make will expand the entire
2161 prerequisites list _twice_: we don't do that as it's a big
2162 backward-compatibility problem. We only replace those specific
2165 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2166 references left in the list of prerequisites. Check for .POSIX as
2167 we record targets, so we can disable non-POSIX behavior while
2168 reading makefiles as well as running them.
2169 (eval): Check the prerequisite list to see if we have anything
2170 that looks like a SysV prerequisite variable reference.
2172 2002-07-09 Paul D. Smith <psmith@gnu.org>
2174 * doc/make.texi (Prerequisite Types): Add a new section describing
2175 order-only prerequisites.
2177 * read.c (uniquize_deps): If we have the same file as both a
2178 normal and order-only prereq, get rid of the order-only prereq,
2179 since the normal one supersedes it.
2181 2002-07-08 Paul D. Smith <psmith@gnu.org>
2183 * AUTHORS: Added Greg McGary to the AUTHORS file.
2184 * NEWS: Blurbed order-only prerequisites.
2185 * file.c (print_file): Show order-only deps properly when printing
2188 * maintMakefile: Add "update" targets for wget'ing the latest
2189 versions of various external files. Taken from Makefile.maint in
2192 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2193 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2195 2002-07-07 Paul D. Smith <psmith@gnu.org>
2197 * po/*.po: Remove. We'll use wget to retrieve them at release
2200 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2201 rather than a shell you get an exception. Make sure we look up
2202 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2204 * remake.c (notice_finished_file): Fix handling of -t flag.
2205 Patch provided by Henning Makholm <henning@makholm.net>.
2207 * implicit.c (pattern_search): Some systems apparently run short
2208 of stack space, and using alloca() in this function caused an
2209 overrun. I modified it to use xmalloc() on the two variables
2210 which seemed like they might get large. Fixes Bug #476.
2212 * main.c (print_version): Update copyright notice to conform with
2214 (print_usage): Update help output.
2216 * function.c (func_eval): Create a new make function, $(eval
2217 ...). Expand the arguments, put them into a buffer, then invoke
2218 eval_buffer() on the resulting string.
2219 (func_quote): Create a new function, $(quote VARNAME). Inserts
2220 the value of the variable VARNAME without expanding it any
2223 * read.c (struct ebuffer): Change the linebuffer structure to an
2224 "eval buffer", which can be either a file or a buffer.
2225 (eval_makefile): Move the code in the old read_makefile() which
2226 located a makefile into here: create a struct ebuffer with that
2227 information. Have it invoke the new function eval() with that
2229 (eval_buffer): Create a new function that creates a struct ebuffer
2230 that holds a string buffer instead of a file. Have it invoke
2231 eval() with that ebuffer.
2232 (eval): New function that contains the guts of the old
2233 read_makefile() function: this function parses makefiles. Obtains
2234 data to parse from the provided ebuffer. Some modifications to
2235 make the flow of the function cleaner and clearer. Still could
2236 use some work here...
2237 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2238 contents of the define/endef variable from the ebuffer.
2239 (readstring): Read the next line from a string-style ebuffer.
2240 (readline): Read the next line from an ebuffer. If it's a string
2241 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2244 * dep.h (eval_buffer): Prototype eval_buffer();
2246 * variable.c (do_variable_definition): Make sure that all
2247 non-target-specific variables are registered in the global set.
2248 If we're invoked from an $(eval ...) we might be inside a $(call
2249 ...) or other function which has pushed a variable scope; we still
2250 want to define our variables from evaluated makefile code in the
2253 2002-07-03 Greg McGary <greg@mcgary.org>
2255 * dep.h (struct dep) [ignore_mtime]: New member.
2256 [changed]: convert to a bitfield.
2257 * implicit.c (pattern_search): Zero ignore_mtime.
2258 * main.c (main, handle_non_switch_argument): Likewise.
2259 * rule.c (convert_suffix_rule): Likewise.
2260 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2261 (read_makefile): Parse '|' in prerequisite list.
2262 (uniquize_deps): Consider ignore_mtime when comparing deps.
2263 * remake.c (update_file_1, check_dep): Don't force remake for
2264 dependencies that have d->ignore_mtime.
2265 * commands.c (FILE_LIST_SEPARATOR): New constant.
2266 (set_file_variables): Don't include a
2267 prerequisite in $+, $^ or $? if d->ignore_mtime.
2270 2002-06-18 Paul D. Smith <psmith@gnu.org>
2272 * make.texinfo: Updates for next revision. New date/rev/etc.
2273 Recreate all Info menus. Change license on the manual to the GNU
2274 Free Documentation License. A number of typos.
2275 (Variables Simplify): Don't use "-" before it's defined.
2276 (Automatic Prerequisites): Rewrite the target example to work
2277 properly if the compile fails. Remove incorrect comments about
2278 how "set -e" behaves.
2279 (Text Functions): Move the "word", "wordlist", "words", and
2280 "firstword" functions here, from "File Name Functions".
2281 * make-stds.texi: Update from latest GNU version.
2282 * fdl.texi: (created) Import the latest GNU version.
2284 2002-06-06 Paul D. Smith <psmith@gnu.org>
2286 * variable.c (do_variable_definition): New function: extract the
2287 part of try_variable_definition() that actually sets the value
2288 into a separate function.
2289 (try_variable_definition): Call do_variable_definition() after
2290 parsing the variable definition string.
2291 (define_variable_in_set): Make the name argument const.
2293 * variable.h (enum variable_flavor): Make public.
2294 (do_variable_definition): Create prototype.
2296 * read.c (read_all_makefiles): Create a new built-in variable,
2298 (read_makefile): Add each makefile read in to this variable value.
2300 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2302 * Makefile.DOS.template: Tweak according to changes in the
2303 distribution. Add back the dependencies of *.o files.
2305 * configh.dos.template: Synchronize with config.h.in.
2307 2002-05-09 Paul D. Smith <psmith@gnu.org>
2309 * file.c (file_timestamp_now): Use K&R function declaration.
2311 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2312 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2313 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2314 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2315 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2316 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2317 nlist.n_name is a pointer rather than an array.
2319 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2320 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2321 * configure.in: Use it instead of the old version.
2323 * main.c (main): Prefer setvbuf() to setlinebuf().
2325 2002-05-08 Paul D. Smith <psmith@gnu.org>
2327 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2328 (loadavg_LDADD): Ditto.
2330 2002-04-29 Paul D. Smith <psmith@gnu.org>
2332 * expand.c (recursively_expand_for_file): Rename
2333 recursively_expand() to recursively_expand_for_file() and provide
2334 an extra argument, struct file. If the argument is provided, set
2335 the variable scope to that of the file before expanding.
2336 * variable.h (recursively_expand): Make this a macro that invokes
2337 recursively_expand_for_file() with a NULL file pointer.
2338 * variable.c (target_environment): Call the renamed function and
2339 provide the current file context.
2340 Fixes Debian bug #144306.
2342 2002-04-28 Paul D. Smith <psmith@gnu.org>
2344 Allow $(call ...) user-defined variables to be self-referencing
2345 without throwing an error. Allows implementation of transitive
2346 closures, among other possibly useful things.
2347 Requested by: Philip Guenther <guenther@sendmail.com>
2349 * variable.h (struct variable): Add a new field: exp_count, and
2350 new macros to hold its size and maximum value.
2351 (warn_undefined): Make this a macro.
2352 * variable.c (define_variable_in_set): Initialize it.
2353 * expand.c (recursively_expand): If we detect recursive expansion
2354 of a variable, check the exp_count field. If it's greater than 0
2355 allow the recursion and decrement the count.
2356 (warn_undefined): Remove this (now a macro in variable.h).
2357 * function.c (func_call): Before we expand the user-defined
2358 function, modify its exp_count field to contain the maximum
2359 number of recursive calls we'll allow. After the call, reset it
2362 2002-04-21 Paul D. Smith <psmith@gnu.org>
2364 Modified to use latest autoconf (2.53), automake (1.6.1), and
2365 gettext (0.11.1). We're using gettext's new "external" support,
2366 to avoid including libintl source with GNU make.
2368 * README.cvs: New file. Explain how to build GNU make from CVS.
2370 * configure.in: Modify checking for the system glob library.
2371 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2372 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2373 etc. will manage it correctly). Set an automake conditional
2374 USE_LOCAL_GLOB to decide whether to compile the glob library.
2376 * getloadavg.c (main): Include make.h in the "TEST" program to
2379 * Makefile.am: Remove special rules for loadavg. Replace them
2380 with Automake capabilities for building extra programs.
2382 * signame.c: This file does nothing if the system provide
2383 strsignal(). If not, it implements strsignal(). If the system
2384 doesn't define sys_siglist, then we make our own; otherwise we use
2386 * signame.h: Removed.
2388 * main.c (main): No need to invoke signame_init(). Update copyright.
2390 * ABOUT-NLS: Removed.
2391 * gettext.c: Removed.
2392 * gettext.h: Get a simplified copy from the gettext package.
2394 * i18n/*.po: Moved to po/.
2397 * config/*: Created. Contains package configuration helper files.
2398 * config.guess, config.sub: Moved to config directory.
2400 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2401 Rework to use new-style autoconf features. Use the "external"
2402 mode for gettext. Make the build.sh config file conditional on
2403 whether build.sh.in exists, to avoid autoconf errors.
2404 * acinclude.m4: Removed almost all macros as being obsolete.
2405 Rewrote remaining macros to use AC_DEFINE.
2406 * acconfig.h: Removed.
2408 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2409 conditional to handle customs support. Remove special handling
2412 2002-04-20 Paul D. Smith <psmith@gnu.org>
2414 * function.c (func_call): Don't mark the argument variables $1,
2415 etc. as recursive. They've already been fully expanded so
2416 there's no need to do it again, and doing so strips escaped $'s.
2417 Reported by Sebastian Glita <glseba@yahoo.com>.
2419 * remake.c (notice_finished_file): Walk through double-colon
2420 entries via the prev field, not the next field!
2421 Reported by Greg McGary <greg@mcgary.org>.
2423 * main.c (main): If the user specifies -q and asks for a specific
2424 target which is a makefile, we got an assert. In that case it
2425 turns out we should continue normally instead.
2427 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2429 * i18n/he.po: Installed a new translation.
2431 2002-01-07 Paul D. Smith <psmith@gnu.org>
2433 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2435 2001-12-04 Paul D. Smith <psmith@gnu.org>
2437 * i18n/ja.po: Installed an updated translation.
2439 2001-09-06 Paul Eggert <eggert@twinsun.com>
2441 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2442 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2444 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2446 (main): Get rid of any avoidable limit on stack size.
2448 2001-09-04 Paul D. Smith <psmith@gnu.org>
2450 * i18n/da.po: Installed an updated translation.
2452 2001-08-03 Paul D. Smith <psmith@gnu.org>
2454 * i18n/fr.po: Installed an updated translation.
2455 Resolves Debian bug #106720.
2457 2001-06-13 Paul D. Smith <psmith@gnu.org>
2459 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2462 2001-06-11 Paul D. Smith <psmith@gnu.org>
2464 * i18n/ko.po: Installed a new translation.
2466 2001-05-06 Paul D. Smith <psmith@gnu.org>
2468 Modify the EINTR handling.
2470 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2471 the way in which we manage the file descriptor/signal handler race
2472 trap to be more efficient.
2474 2001-05-06 Paul Eggert <eggert@twinsun.com>
2476 Restart almost all system calls that are interrupted, instead
2477 of worrying about EINTR. The lone exception is the read() for
2480 * configure.in (HAVE_SA_RESTART): New macro.
2481 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2482 * main.c (main): Use SA_RESTART instead of the old,
2483 nonstandard SA_INTERRUPT.
2485 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2486 * main.c (bsd_signal): New function or macro,
2487 if the implementation doesn't supply it.
2488 (The bsd_signal function will be in POSIX 1003.1-200x.)
2489 (HANDLESIG): Remove.
2490 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2492 * make.h (EINTR_SET): Remove.
2493 (SA_RESTART): New macro.
2495 * arscan.c (ar_member_touch): Don't worry about EINTR.
2496 * function.c (func_shell): Likewise.
2497 * job.c (reap_children, free_child, new_job): Likewise.
2498 * main.c (main): Likewise.
2499 * remake.c (touch_file, name_mtime): Likewise.
2501 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2502 if fstat failed with errno!=EINTR, the error was ignored.
2504 * job.c (set_child_handler_action_flags): New function.
2505 (new_job): Use it to temporarily clear the SIGCHLD action flags
2506 while reading the token.
2508 2001-05-02 Paul D. Smith <psmith@gnu.org>
2510 * job.c (start_job_command): Don't add define/endef per-line flags
2511 to the top-level flags setting.
2513 2001-04-03 Paul D. Smith <psmith@gnu.org>
2515 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2516 bit on error, so check for odd return values, not non-0 return
2518 (VMS_get_member_info): Calculate the timezone differences correctly.
2519 Reported by John Fowler <jfowler@nyx.net>.
2522 2001-03-14 Paul D. Smith <psmith@gnu.org>
2524 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2525 value before invoking define_variable().
2526 Reported by John Fowler <jfowler@nyx.net>.
2528 2001-02-07 Paul D. Smith <psmith@gnu.org>
2530 * read.c (record_target_var): If we reset the variable due to a
2531 command-line variable setting overriding it, turn off the "append"
2534 2001-01-17 Paul D. Smith <psmith@gnu.org>
2536 * variable.c (lookup_variable) [VMS]: When getting values from the
2537 environment, allocate enough space for the _value_ plus escapes,
2538 not enough space for the name plus escapes :-/.
2539 Reported by John Fowler <jfowler@nyx.net>.
2541 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2542 warnings that make generates, so it doesn't look like an error.
2543 Reported by Karl Berry <karl@gnu.org>.
2546 Fix for PR/2020: Rework appended target-specific variables. I'm
2547 fairly confident this algorithm is finally correct.
2549 * expand.c (allocated_variable_append): Rewrite. Instead of
2550 expanding each appended variable then adding all the expanded
2551 strings together, we append all the unexpanded values going up
2552 through the variable set contexts, then expand the final result.
2553 This behaves just like non-target-specific appended variable
2554 values, while the old way didn't in various corner cases.
2555 (variable_append): New function: recursively append the unexpanded
2556 value of a variable, walking from the outermost variable scope to
2558 * variable.c (lookup_variable): Remove the code that looked up the
2559 variable set list if the found variable was "append". We don't
2561 (lookup_variable_in_set): Make this non-static so we can use it
2563 (try_variable_definition): Use lookup_variable_in_set() rather
2564 than faking out current_variable_set_list by hand (cleanup).
2565 * variable.h: Add a prototype for the now non-static
2566 lookup_variable_in_set().
2568 2000-11-17 Paul D. Smith <psmith@gnu.org>
2570 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2571 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2572 before throwing a fit.
2574 2000-11-17 Paul D. Smith <psmith@gnu.org>
2576 * read.c (readline): CRLF calculations had a hole, if you hit the
2577 buffer grow scenario just right. Reworked the algorithm to avoid
2578 the need for len or lastlen at all. Problem description with
2579 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2581 2000-10-24 Paul D. Smith <psmith@gnu.org>
2583 * gettext.c (SWAP): Declare this with the prototype, otherwise
2584 some systems don't work (non-32-bit? Reported for Cray T3E).
2585 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2587 2000-10-05 Paul D. Smith <psmith@gnu.org>
2589 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2590 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2592 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2594 2000-09-22 Paul D. Smith <psmith@gnu.org>
2596 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2597 parts of the real gettext.h here, and we expect to really include
2598 the real gettext.h later. If we keep this #define, it's ignored.
2600 2000-09-21 Paul D. Smith <psmith@gnu.org>
2602 * main.c (log_working_directory): Rework the text to use complete
2603 sentences, to make life simpler for the translators.
2605 2000-08-29 Paul D. Smith <psmith@gnu.org>
2607 * file.c (remove_intermediates): Print a debug message before we
2608 remove intermediate files, so the user (if she uses -d) knows
2611 2000-08-21 Paul D. Smith <psmith@gnu.org>
2613 * variable.c (try_variable_definition): Change how we handle
2614 target-specific append variable defns: instead of just setting the
2615 value, expand it as an append _but_ only within the current
2616 target's context. Otherwise we lose all but the last value if the
2617 variable is appended more than once within the current target
2618 context. Fixes PR/1831.
2620 2000-08-16 Paul D. Smith <psmith@gnu.org>
2622 * function.c (func_shell): Nul-terminate the buffer before
2623 printing an exec error message (just in case it's not!).
2624 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2626 2000-07-25 Paul D. Smith <psmith@gnu.org>
2628 * job.c (construct_command_argv_internal): Add "~" to the list of
2629 sh_chars[] which disallow optimizing out the shell call.
2631 2000-07-23 Paul Eggert <eggert@twinsun.com>
2633 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2634 supersedes --disable-nsec-timestamps.
2635 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2636 * README: Remove --disable-nsec-timestamps.
2638 * filedef.h (struct file.low_resolution_time): New member.
2639 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2640 * remake.c (update_file_1):
2641 Avoid spurious rebuilds due to low resolution time stamps,
2642 generalizing the earlier code that applied only to archive members.
2643 (f_mtime): Archive members always have low resolution time stamps.
2645 * configure.in: Remove --disable-nsec-timestamps, as this has
2646 been superseded by .LOW_RESOLUTION_TIME.
2648 2000-07-23 Paul Eggert <eggert@twinsun.com>
2650 * configure.in (enable_nsec_timestamps): Renamed from
2651 make_cv_nsec_timestamps, since enable/disable options
2652 shouldn't be cached.
2654 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2655 and Paul Eggert <eggert@twinsun.com>
2657 * file.c (file_timestamp_now):
2658 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2659 so that clock_gettime is not linked unless needed.
2661 * filedef.h (FILE_TIMESTAMP_HI_RES):
2662 Remove definition; "configure" now does this.
2664 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2665 to before high resolution file timestamp check,
2666 since that check now uses uintmax_t.
2667 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2668 high resolution file timestamps.
2669 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2670 so that we don't link in clock_gettime unnecessarily.
2672 2000-07-17 Paul D. Smith <psmith@gnu.org>
2674 * i18n/ja.po: New version of the translation file.
2676 2000-07-07 Paul D. Smith <psmith@gnu.org>
2678 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2679 the offset calculation.
2680 (name_mtime): Replace EINTR test with EINTR_SET macro.
2682 2000-07-07 Paul Eggert <eggert@twinsun.com>
2686 * remake.c (update_file_1):
2687 Avoid spurious rebuilds of archive members due to their
2688 timestamp resolution being only one second.
2689 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2690 the clock's resolution being lower than file timestamps'.
2691 When warning about future timestamps, report only the discrepancy,
2692 not the absolute value of the timestamp and the current time.
2694 * file.c (file_timestamp_now): New arg RESOLUTION.
2695 * filedef.h (file_timestamp_now): Likewise.
2696 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2698 2000-07-05 Paul D. Smith <psmith@gnu.org>
2700 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2701 to listp. Fixes PR/1793.
2703 2000-06-26 Paul Eggert <eggert@twinsun.com>
2705 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2707 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2709 * remake.c (f_mtime): Remove unused var memtime.
2711 2000-06-25 Martin Buchholz <martin@xemacs.org>
2713 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2714 Ran spell-check on make.texinfo.
2716 2000-06-23 Paul D. Smith <psmith@gnu.org>
2718 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2719 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2720 * make.h: Define these macros.
2722 * Version 3.79.1 released.
2724 * configure.in: Add a new option, --disable-nsec-timestamps, to
2725 avoid using sub-second timestamps on systems that support it. It
2726 can lead to problems, e.g. if your makefile relies on "cp -p".
2727 * README.template: Document the issue with "cp -p".
2729 * config.guess, config.sub: Updated.
