32 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
33 (html, make_1.html): New targets.
35 (.SUFFIXES): Add .html.

39 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
40 HAVE_DECL_SYS_SIGLIST.
42 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
43 build does not use child_execute_job.
45 * variable.c (define_automatic_variables) [__MSDOS__]: Always

67 * remake.c (f_mtime): Print time difference values between 100 and
68 ULONG_MAX in fixed-point notation rather than in exponention notation.
70 2007-10-12 Eli Zaretskii <eliz@gnu.org>
72 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
73 a more complex value than a simple shell: if it's not a default
74 shell now then expand it and see if is a default shell then.
76 2007-10-10 Eli Zaretskii <eliz@gnu.org>
78 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
79 pathnames, with const strings.
80 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

112 2007-09-10 Paul Smith <psmith@gnu.org>
114 * commands.c (print_commands): Don't print an extra line in the
115 command scripts. Prefix the command scripts with cmd_prefix, not \t.

129 * read.c (eval): Remove the cmd_prefix characters from the command
130 scripts here, so they're not stored in the commands array at all,
131 rather than waiting and stripping them out during command construction.
132 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
134 2007-08-15 Paul Smith <psmith@gnu.org>
136 * doc/make.texi (GNU Free Documentation License): The fdl.texi
137 file has had the section info removed, so add some to make.texi

179 "Expansion of a deferred"
180 Fixes Savannah bug #20018.
182 * expand.c (variable_expand_for_file): Preserve the value of

200 Dave Korn <dave.korn@artimi.com>
202 2007-05-08 Paul Smith <psmith@gnu.org>
204 Fix Savannah bug #19656:
206 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
208 * make.h: Change all case-insensitive string compares to use
209 strcasecmp() (from POSIX). If we don't have that but do have one
210 of the others, define strcasecmp to be one of those instead. If
211 we don't have any, declare a prototype for our own version.
213 * misc.c (strcasecmp): Use this if we can't find any native
214 case-insensitive string comparison function.
215 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
216 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
218 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
219 strcasecmp() instead of stricmp().
220 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
221 instead of strcmpi().
222 * acinclude.m4: Remove the strcasecmp() check from here.
224 2007-03-21 Paul Smith <psmith@gnu.org>
226 * configure.in: Don't turn on case-insensitive file system support
227 if --disable-... is given. Fixes Savannah bug #19348.
229 2007-03-19 Paul Smith <psmith@gnu.org>
231 * ALL: Use the strcache for all file name strings, or other
232 strings which we will never free. The goal is to save memory by
233 avoiding duplicate copies of strings. However, at the moment this
234 doesn't save much memory in most situations: due to secondary
235 expansion we actually save prerequisite lists twice (once before
236 the secondary expansion, and then again after it's been parsed
237 into individual file names in the dep list). We will resolve this
238 in a future change, by doing the parsing up-front for targets
239 where secondary expansion is not set.
241 Moving things into the strcache also allows us to use const
242 pointers in many more places.
244 2007-01-03 Paul Smith <psmith@gnu.org>
246 * make.h (ENULLLOOP): Reset errno after each failed invocation of
247 the function, not just the first. Fixes Savannah bug #18680.
249 2006-11-18 Paul Smith <psmith@gnu.org>
251 * strcache.c (strcache_add_len): Don't allocate a new buffer
252 unless the string is not already nil-terminated. Technically this
253 is a violation of the standard, since we may be passed an array
254 that is not long enough to test one past. However, in make this
255 is never true since we only use nil-terminated strings or
258 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
260 * main.c: New global cmd_prefix, defaults to '\t'.
261 * job.c (construct_command_argv_internal): Use cmd_prefix instead
265 (dir_contents_file_exists_p): Check for an error return from
266 readdir(), just in case.
268 * commands.c: Constified.
269 * default.c: Constified.
270 * expand.c: Constified.
271 * function.c: Partial constification.
272 * variable.c: Partial constification.
273 * vmsify.c: Constification. Hard to test this but I hope I didn't

276 * w32/pathstuff.c: Partial constification.
278 2006-11-16 Eli Zaretskii <eliz@gnu.org>
280 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
281 backslashes and drive letters as absolute.
283 2006-10-22 Paul Smith <psmith@gnu.org>
285 * main.c (struct command_switch): Use const and void*.
287 2006-10-21 Paul Smith <psmith@gnu.org>
290 * arscan.c: Constified.
292 2006-09-30 Paul Smith <psmith@gnu.org>
294 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
295 point to lastword since the example was updated.
296 Fixes Savannah bug #16304.
297 (Secondary Expansion): Correct example description.
298 Fixes Savannah bug #16468.
299 (Makefile Contents): Clarify that comments cannot appear within
300 variable references or function calls.
301 Fixes Savannah bug #16577.
302 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
303 Fixes Savannah bug #17701.
304 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
305 (Prerequisite Types): Added an example of using order-only
306 prerequisites. Fixes Savannah bug #17880.
307 (Rule Syntax): "lise" -> "list"
308 (Multiple Rules): ... -> @dots{}
309 (Splitting Lines): ditto.

346 2006-04-26 Paul D. Smith <psmith@gnu.org>
348 * README.cvs: Add a reminder to notify the GNU translation robot.
350 * doc/make.texi: Change @direcategory (requested by Karl Berry).
352 2006-04-20 Paul D. Smith <psmith@gnu.org>
354 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
355 that don't have extended grep.
356 (cvsclean): Use $(PERL) instead of perl.
358 2006-04-09 Paul D. Smith <psmith@gnu.org>
360 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
362 * expand.c, implicit.c, main.c, read.c: Rename variables so that
363 inner-scope variables don't mask outer-scope variables.
365 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

370 don't need to be cast. Also remove (char *) casts of arguments to
373 * configure.in: Remove checks for memcpy/memmove/strchr.
375 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.
377 * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp
378 calls to memset/memcpy/memmove/memcmp calls.

426 2006-03-23 Paul D. Smith <psmith@gnu.org>

432 Fixes Savannah bug #16166.
434 * misc.c (log_access): Takes a const char *.

485 (allocated_variable_append): Don't expand the final result.
486 Fixes Savannah bug #15913.
488 2006-03-09 Paul Smith <psmith@gnu.org>
490 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
491 listed non-existent files as changed. Turns out there's a bug in
492 the Linux kernel builds which means that this change causes
493 everything to rebuild every time. We will re-introduce this fix
494 in the next release, to give them time to fix their build system.
495 Fixes Savannah bug #16002.
496 Introduces Savannah bug #16051.

513 2006-02-19 Paul D. Smith <psmith@gnu.org>
515 * commands.c (set_file_variables): Realloc, not malloc, the static
516 string values to avoid memory leaks.
518 * expand.c (recursively_expand_for_file): Only set reading_file to
519 an initialized value.
521 * implicit.c (pattern_search): We need to make a copy of the stem
522 if we get it from an intermediate dep, since those get freed.
524 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
526 (enter_file) [VMS]: Ditto.

533 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
534 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
535 the calls to _beginthreadex.
537 * expand.c (recursively_expand_for_file): Initialize `save' to
538 prevent compiler warnings.
540 2006-02-18 Eli Zaretskii <eliz@gnu.org>

548 * variable.c (merge_variable_set_lists): Don't try to merge the
549 global_setlist. Not only is this useless, but it can lead to
550 circularities in the linked list, if global_setlist->next in one
551 list gets set to point to another list which also ends in

559 * expand.c (expanding_var): Keep track of which variable we're
560 expanding. If no variable is being expanded, it's the same as
562 * make.h (expanding_var): Declare it.
563 * expand.c (recursively_expand_for_file): Set expanding_var to the
564 current variable we're expanding, unless there's no file info in
565 it (could happen if it comes from the command line or a default
566 variable). Restore it before we exit.
567 * expand.c (variable_expand_string): Use the expanding_var file
568 info instead of the reading_file info.
569 * function.c (check_numeric): Ditto.
571 (func_wordlist): Ditto.
573 (expand_builtin_function): Ditto.
574 (handle_function): Ditto.
576 2006-02-14 Paul D. Smith <psmith@gnu.org>
578 * read.c (eval): Even if the included filenames expands to the
579 empty string we still need to free the allocated buffer.
581 * implicit.c (pattern_search): If we allocated a variable set for
582 an impossible file, free it.
583 * variable.c (free_variable_set): New function.
584 * variable.h: Declare it.
586 * read.c (read_all_makefiles): Makefile names are kept in the
587 strcache, so there's never any need to alloc/free them.
590 * main.c (main): Add "archives" to the .FEATURES variable if
591 archive support is enabled.
592 * doc/make.texi (Special Variables): Document it.
594 2006-02-13 Paul D. Smith <psmith@gnu.org>
596 * implicit.c (pattern_search): Add checking for DOS pathnames to
597 the pattern rule target LASTSLASH manipulation.
598 Fixes Savannah bug #11183.
600 2006-02-11 Paul D. Smith <psmith@gnu.org>
602 * (ALL FILES): Updated copyright and license notices.
604 2006-02-10 Paul D. Smith <psmith@gnu.org>
606 A new internal capability: the string cache is a read-only cache
607 of strings, with a hash table interface for fast lookup. Nothing
608 in the cache will ever be freed, so there's no need for reference
609 counting, etc. This is the beginning of a full solution for
610 Savannah bug #15182, but for now we only store makefile names here.
612 * strcache.c: New file. Implement a read-only string cache.
613 * make.h: Add prototypes for new functions.
614 * main.c (initialize_global_hash_tables): Initialize the string cache.
615 (print_data_base): Print string cache stats.
616 * read.c (eval_makefile): Use the string cache to store makefile
617 names. Rewrite the string allocation to be sure we free everything.
619 2006-02-10 Eli Zaretskii <eliz@gnu.org>
621 * dir.c (dir_contents_file_exists_p): Don't opendir if the
622 directory time stamp didn't change, except on FAT filesystems.
623 Suggested by J. David Bryan <jdbryan@acm.org>.
625 2006-02-09 Paul D. Smith <psmith@gnu.org>
627 * function.c (func_or): Implement a short-circuiting OR function.
628 (func_and): Implement a short-circuiting AND function.
629 (function_table_init): Update the table with the new functions.
630 * doc/make.texi (Conditional Functions): Changed the "if" section
631 to one on general conditional functions. Added documentation for
632 $(and ...) and $(or ...) functions.
633 * NEWS: Note new $(and ...) and $(or ...) functions.
635 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
637 * job.h (struct child): Add the dontcare bitfield.
638 * job.c (new_job): Cache dontcare flag.
639 * job.c (reap_children): Use cached dontcare flag instead of the
640 one in struct file. Fixes Savannah bug #15641.
642 2006-02-06 Paul D. Smith <psmith@gnu.org>
644 * vpath.c (selective_vpath_search): If the file we find has a
645 timestamp from -o or -W, use that instead of the real time.
646 * remake.c (f_mtime): If the mtime is a special token from -o or
647 -W, don't overwrite it with the real mtime.
648 Fixes Savannah bug #15341.
650 Updates from Markus Mauhart <qwe123@chello.at>:
652 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

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

692 * prepare_w32.bat: Remove this file from the distribution.
694 2006-01-21 Eli Zaretskii <eliz@gnu.org>
696 * remake.c (update_goal_chain): Set g->changed instead of
697 incrementing it, as it is only 8-bit wide, and could overflow if
698 many commands got started in update_file.
700 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
702 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
703 MAXIMUM_WAIT_OBJECTS.

711 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
712 are already more children than sub_proc.c can handle, behave as if
713 the load were too high.
714 (start_job_command): Fix a typo in error message when process_easy
717 2006-01-14 Eli Zaretskii <eliz@gnu.org>
719 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
720 the shell is not sh.exe.
722 * job.c (create_batch_file): Renamed from create_batch_filename;
723 all callers changed. Don't close the temporary file; return its
724 file descriptor instead. New arg FD allows to return the file
726 (construct_command_argv_internal): Use _fdopen instead of fopen to
729 2006-01-04 Paul D. Smith <psmith@gnu.org>
731 * readme.vms: Updates for case-insensitive VMS file systems from
732 Hartmut Becker <Hartmut.Becker@hp.com>.

743 * remake.c (update_file_1): Mark a prerequisite changed if it
746 * read.c (eval): Be sure to strip off trailing whitespace from the
747 prerequisites list properly. Also, initialize all fields in
748 struct dep when creating a new one.
750 2005-12-28 Paul D. Smith <psmith@gnu.org>
752 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
753 disable warnings for MSC.

756 2005-12-17 Eli Zaretskii <eliz@gnu.org>
758 * doc/make.texi (Execution): Add a footnote about changes in
759 handling of backslash-newline sequences. Mention the differences
760 on MS-DOS and MS-Windows.
762 * NEWS: More details about building the MinGW port and a pointer
763 to README.W32. Fix the section name that describes the new
764 backward-incompatible processing of backslash-newline sequences.
765 The special processing of SHELL set to "cmd" is only relevant to
766 MS-Windows, not MS-DOS.
768 2005-12-17 Eli Zaretskii <eliz@gnu.org>
770 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
771 to DWORD, to avoid compiler warnings.
772 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
773 use %ld in format, to avoid compiler warnings.

789 garbage happened to be on the heap.
791 2005-12-12 Paul D. Smith <psmith@gnu.org>
793 * make.1: Fix some display errors and document all existing options.
794 Patch provided by Mike Frysinger <vapier@gentoo.org>.
796 2005-12-11 Paul D. Smith <psmith@gnu.org>
798 * implicit.c (pattern_search): If 2nd expansion is not set for
799 this implicit rule, replace the pattern with the stem directly,
800 and don't re-expand the variable list. Along with the other
801 .SECONDEXPANSION changes below, fixes bug #13781.
803 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
805 * implicit.c (pattern_search): Mark other files that this rule
806 builds as targets so that they are not treated as intermediates
807 by the pattern rule search algorithm. Fixes bug #13022.
809 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
811 * remake.c (notice_finished_file): Propagate the change of
812 modification time to all the double-colon entries only if

831 * read.c (record_files): Don't set deps flags if there are no deps.
832 * maintMakefile: We only need to build the templates when we are
833 creating a distribution, so don't do it for "all".
835 2005-10-24 Paul D. Smith <psmith@gnu.org>
837 Make secondary expansion optional: its enabled by declaring the
838 special target .SECONDEXPANSION.
840 * NEWS: Update information on second expansion capabilities.
841 * doc/make.texi (Secondary Expansion): Document the
842 .SECONDEXPANSION special target and its behavior.
843 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
844 prerequisite list was found in a static pattern rule.
845 (free_dep_chain): Declare a prototype.
846 * file.c (parse_prereqs): New function: break out some complexity
848 (expand_deps): If we aren't doing second expansion, replace % with
849 the stem for static pattern rules. Call the new function.
850 * filedef.h (parse_prereqs): Declare a prototype.
851 * implicit.c (pattern_search): Initialize the new staticpattern
853 * main.c (second_expansion): Declare a global variable to remember

857 * misc.c (free_dep_chain): New function: frees a struct dep list.
858 * read.c (read_all_makefiles): Initialize the staticpattern field.
859 (eval_makefile): Ditto.
860 (record_files): Check for the .SECONDEXPANSION target and set
861 second_expansion global if it's found.
862 Use the new free_dep_chain() instead of doing it by hand.
863 Set the staticpattern field for prereqs of static pattern targets.
865 2005-10-16 Paul D. Smith <psmith@gnu.org>
867 * main.c (main): Set CURDIR to be a file variable instead of a
868 default, so that values of CURDIR inherited from the environment
869 won't override the make value.
871 2005-09-26 Paul D. Smith <psmith@gnu.org>
873 * job.c (construct_command_argv_internal): If the line is empty
874 remember to free the temporary argv strings.
877 2005-09-16 Paul D. Smith <psmith@gnu.org>
879 * job.c (start_job_command): The noerror flag is a boolean (single
880 bit); set it appropriately.
881 Reported by Mark Eichin <eichin@metacarta.com>
883 2005-08-29 Paul D. Smith <psmith@gnu.org>
885 * function.c (func_error): On Windows, output from $(info ...)
886 seems to come in the wrong order. Try to force it with fflush().
888 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
890 * read.c (record_files): Move code that sets stem for static
891 pattern rules out of the if (!two_colon) condition so it is
892 also executed for two-colon rules. Fixes Savannah bug #13881.
894 2005-08-08 Paul D. Smith <psmith@gnu.org>
896 * make.h: Don't test that __STDC__ is non-0. Some compilers
897 (Windows for example) set it to 0 to denote "ISO C + extensions".
900 2005-08-07 Paul D. Smith <psmith@gnu.org>
902 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
903 conditional (slightly different version of a fix from Eli).
905 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
906 If make is running in parallel without -k and two jobs die in a
907 row, but not too close to each other, then make will quit without
908 waiting for the rest of the jobs to die.
910 * main.c (die): Don't reset err before calling reap_children() the
911 second time: we still want it to be in the error condition.
912 * job.c (reap_children): Use a static variable, rather than err,
913 to control whether or not the error message should be printed.
915 2005-08-06 Eli Zaretskii <eliz@gnu.org>
917 * w32/subproc/sub_proc.c: Include signal.h.
918 (process_pipe_io, process_file_io): Pass a pointer to a local
919 DWORD variable to GetExitCodeProcess. If the exit code is
920 CONTROL_C_EXIT, put SIGINT into pproc->signal.
922 * job.c [WINDOWS32]: Include windows.h.
923 (main_thread) [WINDOWS32]: New global variable.
924 (reap_children) [WINDOWS32]: Get the handle for the main thread
925 and store it in main_thread.
927 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
928 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
929 doing anything else. When we are done, close the main thread
930 handle and exit with status 130.
932 2005-07-30 Eli Zaretskii <eliz@gnu.org>
934 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
937 * main.c (find_and_set_default_shell): If found a DOSish shell,
938 set sh_found and the value of default_shell, and report the
939 findings in debug mode.
941 * job.c (construct_command_argv_internal): Check unixy_shell, not
942 no_default_sh_exe, to decide whether to use Unixy or DOSish
945 * README.W32: Update with info about the MinGW build.
947 * build_w32.bat: Support MinGW.
949 * w32/subproc/build.bat: Likewise.
951 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
954 * function.c (windows32_openpipe): Fix format strings for printing
957 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
959 (start_job_command): Fix format string for printing the result of
961 (start_job_command) [WINDOWS32]: Do not define.
962 (exec_command): Fix format string for printing HANDLE args.
964 * main.c (handle_runtime_exceptions): Fix sprintf format strings
965 to avoid compiler warnings.
966 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
967 (Note: some of these fixes were submitted independently by J. Grant)
969 2005-07-30 J. Grant <jg@jguk.org>
971 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
972 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
973 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
975 2005-07-15 Paul Smith <psmith@gnu.org>
977 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
978 we don't have a POSIX shell, then revert to the old
979 backslash-newline behavior (where they are stripped).
982 2005-07-08 Paul D. Smith <psmith@gnu.org>
984 * config.h.W32.template: Reorder to match the standard config.h,
985 for easier comparisons.
986 From J. Grant <jg@jguk.org>
988 * maintMakefile: Remove .dep_segment before overwriting it, in
989 case it's not writable or noclobber is set.
990 * expand.c (variable_expand_string): Cast result of pointer
991 arithmetic to avoid a warning.
992 * main.c (switches): Add full-fledged final initializer.
994 2005-07-06 Paul D. Smith <psmith@gnu.org>
996 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
997 * signame.c (strsignal): If we found _sys_siglist[] or
998 __sys_siglist[] use those instead of sys_siglist[].
999 From Albert Chin <china@thewrittenword.com>
1001 2005-07-04 Paul D. Smith <psmith@gnu.org>
1003 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1004 globfree(); set up to use the GNU versions.
1005 From Martin Zinser <zinser@zinser.no-ip.info>
1007 2005-07-03 Paul D. Smith <psmith@gnu.org>
1009 From J. Grant <jg@jguk.org>:

1019 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1020 declaration was checked but not present.
1022 2005-06-27 Paul D. Smith <psmith@gnu.org>
1024 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1025 to unsigned long. Fixes Savannah bug #13550.
1027 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1028 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1029 Fixes Savannah bug #13551.
1031 2005-06-26 Paul D. Smith <psmith@gnu.org>
1033 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1034 it if ANSI_STRING is not set.
1036 2005-06-25 Paul D. Smith <psmith@gnu.org>
1038 * read.c (eval): If no filenames are passed to any of the
1039 "include" variants, don't print an error.
1040 * doc/make.texi (Include): Document this.
1041 Fixes Savannah bug #1761.
1043 * job.c (construct_command_argv_internal): Sanitize handling of
1044 backslash/newline pairs according to POSIX: that is, keep the
1045 backslash-newline in the command script, but remove a following
1046 TAB character, if present. In the fast path, make sure that the
1047 behavior matches what the shell would do both inside and outside
1048 of quotes. In the slow path, quote the backslash and put a
1049 literal newline in the string.
1050 Fixes Savannah bug #1332.
1051 * doc/make.texi (Execution): Document the new behavior and give
1053 * NEWS: Make a note of the new behavior.
1055 * make.h [WINDOWS32]: #include <direct.h>.
1056 Fixes Savannah bug #13478.
1058 * remake.c (name_mtime): If the stat() of a file fails and the -L
1059 option was given and the file is a symlink, take the best mtime of
1060 the symlink we can get as the mtime of the file and don't fail.
1061 Fixes Savannah bug #13280.
1063 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1064 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1065 inside a variable reference. Make this function static as it's
1067 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1068 parsing an unexpanded line looking for semicolons.
1069 Fixes Savannah bug #1454.
1070 * misc.c (remove_comments): Move this to read.c and make it static
1071 as it's only used there. Call find_char_unquote() with new arg.
1072 * make.h: Remove prototypes for find_char_unquote() and
1073 remove_comments() since they're static now.
1075 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1076 its export flag and obtain its value. When we need to re-exec,
1077 increment the value and add it into the environment.
1078 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1079 * NEWS: Mention MAKE_RESTARTS.
1080 * main.c (always_make_set): New variable. Change the -B option to
1081 set this one instead.
1082 (main): When checking makefiles, only set always_make_flag if
1083 always_make_set is set AND the restarts flag is 0. When building
1084 normal targets, set it IFF always_make_set is set.
1085 (main): Avoid infinite recursion with -W, too: only set what-if
1086 files to NEW before we check makefiles if we've never restarted
1087 before. If we have restarted, set what-if files to NEW _after_ we
1089 Fixes Savannah bug #7566:
1091 2005-06-17 Paul D. Smith <psmith@gnu.org>
1093 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1094 in the prerequisites list.
1096 2005-06-12 Paul D. Smith <psmith@gnu.org>
1098 Fix Savannah bug # 1328.
1100 * configure.in: Check for atexit().
1101 * misc.c (close_stdout): Test stdout to see if writes to it have
1102 failed. If so, be sure to exit with a non-0 error code. Based on
1103 code found in gnulib.
1104 * make.h: Prototype.
1105 * main.c (main): Install close_stdout() with atexit().
1107 2005-06-10 Paul D. Smith <psmith@gnu.org>
1109 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1111 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1112 headers; make vmsWaitForChildren() static; extern vmsify().
1113 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1114 Don't create child_execute_job() here (it's in vmsjobs.c).
1115 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1117 2005-06-09 Paul D. Smith <psmith@gnu.org>
1119 * variable.c (push_new_variable_scope): File variables point
1120 directly to the global_setlist variable. So, inserting a new
1121 scope in front of that has no effect on those variables: they
1122 don't go through current_variable_set_list. If we're pushing a
1123 scope and the current scope is global, push it "the other way" so
1124 that the new setlist is in the global_setlist variable, and
1125 next points to a new setlist with the global variable set.
1126 (pop_variable_scope): Properly undo a push with the new
1128 Fixes Savannah bug #11913.
1130 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1132 * job.c (reap_children): Don't die of the command failed but
1133 the dontcare flag is set. Fixes Savannah bug #13216.
1135 * implicit.c (pattern_search): When creating a target from
1136 an implicit rule match, lookup pattern target and set precious
1137 flag in a newly created target. Fixes Savannah bug #13218.
1139 2005-05-13 Paul D. Smith <psmith@gnu.org>
1141 Implement "if... else if... endif" syntax.
1143 * read.c (eval): Push all checks for conditional words ("ifeq",
1144 "else", etc.) down into the conditional_line() function.
1145 (conditional_line): Rework to allow "else if..." clause. New
1146 return value -2 for lines which are not conditionals. The
1147 ignoring flag can now also be 2, which means "already parsed a
1148 true branch". If that value is seen no other branch of this
1149 conditional can be considered true. In the else parsing if there
1150 is extra text after the else, invoke conditional_line()
1151 recursively to see if it's another conditional. If not, it's an
1152 error. If so, raise the conditional value to this level instead
1153 of creating a new conditional nesting level. Special check for
1154 "else" and "endif", which aren't allowed on the "else" line.
1155 * doc/make.texi (Conditional Syntax): Document the new syntax.
1157 2005-05-09 Paul D. Smith <psmith@gnu.org>
1159 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1160 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1161 recurses to the w32 directory, even on non-Windows systems. Use
1162 the method suggested in the automake manual.
1163 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1164 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1166 2005-05-07 Paul D. Smith <psmith@gnu.org>
1168 * main.c (die): If we're dying with a fatal error (not that a
1169 command has failed), write back any leftover tokens before we go.
1171 * job.c (set_child_handler_action_flags): If there are jobs
1172 waiting for the load to go down, set an alarm to go off in 1
1173 second. This allows us to wake up from a potentially long-lasting
1174 read() and start a new job if the load has gone down. Turn it off
1176 (job_noop): Dummy signal handler function.
1177 (new_job): Invoke it with the new semantics.
1179 * docs/make.texi: Document secondary expansion. Various cleanups
1182 2005-05-03 Paul D. Smith <psmith@gnu.org>
1184 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1185 the targets which are to ultimately be made are called "goals";
1186 see the GNU make manual. Also, MAKECMDGOALS, etc.
1188 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1189 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1190 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1192 2005-05-02 Paul D. Smith <psmith@gnu.org>
1194 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1195 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1196 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1197 functions to vmsjobs.c. #include it into jobs.c.
1199 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1200 jobserver tokens. I found that this happens when an exported
1201 recursive variable contains a $(shell ...) function reference: in
1202 this situation we could "forget" to write back a token.
1204 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1205 we have. It's not reliable to depend on the number of children in
1206 our linked list so keep a separate count.
1207 (new_job): Check jobserver_tokens rather than children &&
1208 waiting_jobs. Increment jobserver_tokens when we get one.
1209 (free_child): If jobserver_tokens is 0, internal error. If it's
1210 >1, write a token back to the jobserver pipe (we don't write a
1211 token for the "free" job). Decrement jobserver_tokens.
1213 * main.c: Add variable master_job_slots.
1214 (main): Set it to hold the number of jobs requested if we're the
1215 master process, when using the jobserver.
1216 (die): Sanity checks: first test jobserver_tokens to make sure
1217 this process isn't holding any tokens we didn't write back.
1218 Second, if master_job_slots is set count the tokens left in the
1219 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1221 2005-04-24 Paul D. Smith <psmith@gnu.org>
1223 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1224 with -l# can lose jobserver tokens, because waiting jobs are not
1225 consulted properly when checking for the "free" token.
1227 * job.c (free_child): Count waiting_jobs as having tokens.
1228 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1229 handle jobs waiting for the load to drop.
1231 2005-04-23 Paul D. Smith <psmith@gnu.org>
1233 * main.c (main): Be careful to not core if a variable setting in
1234 the environment doesn't contain an '='. This is illegal but can
1235 happen in broken setups.
1236 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1238 2005-04-12 Paul D. Smith <psmith@gnu.org>
1240 The second expansion feature causes significant slowdown. Timing
1241 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1242 read the makefile before the feature, to 11+s to do the same
1243 operations after the feature. Additionally, memory usage
1244 increased drastically. To fix this I added some intelligence that
1245 avoids the overhead of the second expansion unless it's required.
1247 * dep.h: Add a new boolean field, need_2nd_expansion.
1249 * read.c (eval): When creating the struct dep for the target,
1250 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1251 (record_files): If there's a "%" in a static pattern rule, it gets
1252 converted to "$*" so set need_2nd_expansion to 1.
1254 * file.c (expand_deps): Rework to be more efficient. Only perform
1255 initialize_file_variables(), set_file_variables(), and
1256 variable_expand_for_file() if the need_2nd_expansion is set.
1258 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1259 (pattern_search): Ditto.
1260 * main.c (handle_non_switch_argument): Ditto.
1262 * read.c (read_all_makefiles): Ditto.
1263 (eval_makefile): Ditto.
1265 2005-04-07 Paul D. Smith <psmith@gnu.org>
1267 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1268 * variable.c (sync_Path_environment): Ditto.
1269 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1271 * main.c (main): Define the .FEATURES variable.
1272 * NEWS: Announce .FEATURES.
1273 * doc/make.texi (Special Variables): Document .FEATURES.
1275 * remake.c (check_dep): If a file is .PHONY, update it even if
1276 it's marked intermediate. Fixes Savannah bug #12331.
1278 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1280 * file.c (expand_deps): Factor out the second expansion and
1281 prerequisite line parsing logic from snap_deps().
1283 * file.c (snap_deps): Use expand_deps(). Expand and parse
1284 prerequisites of the .SUFFIXES special target first. Fixes
1285 Savannah bug #12320.
1287 2005-03-13 Paul D. Smith <psmith@gnu.org>
1289 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1292 2005-03-11 Paul D. Smith <psmith@gnu.org>
1294 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1295 available, not undefined (from Earnie Boyd).
1297 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1299 * implicit.c (pattern_search): Mark an intermediate target as
1300 precious if it happened to be a prerequisite of some (other)
1301 target. Fixes Savannah bug #12267.
1303 2005-03-09 Paul D. Smith <psmith@gnu.org>
1305 * read.c (eval_makefile): Add alloca(0).
1306 (eval_buffer): Ditto.
1308 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1310 * main.c (main): Use o_file instead of o_default when defining
1311 the .DEFAULT_TARGET special variable.
1312 * read.c (eval): Use define_variable_global() instead of
1313 define_variable() when setting new value for the .DEFAULT_TARGET
1314 special variable. Fixes Savannah bug #12266.
1316 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1318 * imlicit.c (pattern_search): Mark files for which an implicit
1319 rule has been found as targets. Fixes Savannah bug #12202.
1321 2005-03-04 Paul D. Smith <psmith@gnu.org>
1324 * doc/make.texi (Automatic Variables): Document $|.
1326 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1328 * read.c (record_files): Instead of substituting % with
1329 actual stem value in dependency list replace it with $*.
1330 This fixes stem triple expansion bug.
1332 * implicit.c (pattern_search): Copy stem to a separate
1333 buffer and make it a properly terminated string. Assign
1334 this buffer instead of STEM (which is not terminated) to
1335 f->stem. Instead of substituting % with actual stem value
1336 in dependency list replace it with $*. This fixes stem
1337 triple expansion bug.
1339 2005-03-01 Paul D. Smith <psmith@gnu.org>
1341 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1342 on Windows, as it takes a handle not a pid. Just exit.
1343 Fix from patch #3679, provided by Alessandro Vesely.
1345 * configure.in: Update check for sys_siglist[] from autoconf manual.
1346 * signame.c (strsignal): Update to use the new autoconf macro.
1348 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1350 * read.c (record_files): Add a check for the list of prerequisites
1351 of a static pattern rule being empty. Fixes Savannah bug #12180.
1353 2005-02-28 Paul D. Smith <psmith@gnu.org>
1355 * doc/make.texi (Text Functions): Update docs to allow the end
1356 ordinal for $(wordlist ...) to be 0.
1357 * function.c (func_wordlist): Fail if the start ordinal for
1358 $(wordlist ...) is <1. Matches documentation.
1359 Resolves Savannah support request #103195.
1361 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1362 previously we were stopping when !-q, exactly the opposite. This
1363 has been wrong since version 1.34, in 1994!
1364 (update_file): If we got an error don't break out to run more
1365 double-colon rules: just return immediately.
1366 Fixes Savannah bug #7144.
1368 2005-02-27 Paul D. Smith <psmith@gnu.org>
1370 * misc.c (end_of_token): Make argument const.
1371 * make.h: Update prototype.
1373 * function.c (abspath, func_realpath, func_abspath): Use
1374 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1375 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1376 * read.c (record_files): Ditto.
1377 * variable.c (do_variable_definition): Ditto.
1379 * function.c (func_error): Create a new function $(info ...) that
1380 simply prints the message to stdout with no extras.
1381 (function_table_init): Add new function to the table.
1382 * NEWS: Add $(info ...) reference.
1383 * doc/make.texi (Make Control Functions): Document it.
1385 New feature: if the system supports symbolic links, and the user
1386 provides the -L/--check-symlink-time flag, then use the latest
1387 mtime between the symlink(s) and the target file.
1389 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1390 readlink(). If both are available, define MAKE_SYMLINKS.
1391 * main.c: New variable: check_symlink_flag.
1392 (usage): Add a line for -L/--check-symlink-times to the help string.
1393 (switches): Add -L/--check-symlink-times command line argument.
1394 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1395 print a warning and disable it again.
1396 * make.h: Declare check_symlink_flag.
1397 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1398 if the file is a symlink then check each link in the chain and
1399 choose the NEWEST mtime we find as the mtime for the file. The
1400 newest mtime might be the file itself!
1401 * NEWS: Add information about this new feature.
1402 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1404 Avoid core dumps described in Savannah bug # 12124:
1406 * file.c: New variable snapped_deps remember whether we've run
1408 (snap_deps): Set it.
1409 * filedef.h: Extern it.
1410 * read.c (record_files): Check snapped_deps; if it's set then
1411 we're trying to eval a new target/prerequisite relationship from
1412 within a command script, which we don't support. Fatal.
1414 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1416 Implementation of the .DEFAULT_TARGET special variable.
1418 * read.c (eval): If necessary, update default_target_name when
1420 * read.c (record_files): Update default_target_file if
1421 default_target_name has changed.
1422 * main.c (default_target_name): Define.
1423 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1424 default_target_name is set use default_target_file as a root
1426 * filedef.h (default_target_name): Declare.
1427 * dep.h (free_dep_chain):
1428 * misc.c (free_dep_chain): Change to operate on struct nameseq
1429 and change name to free_ns_chain.
1430 * file.c (snap_deps): Update to use free_ns_chain.
1432 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1434 Implementation of the second expansion in explicit rules,
1435 static pattern rules and implicit rules.
1437 * read.c (eval): Refrain from chopping up rule's dependencies.
1438 Store them in a struct dep as a single dependency line. Remove
1439 the code that implements SySV-style automatic variables.
1441 * read.c (record_files): Adjust the code that handles static
1442 pattern rules to expand all percents instead of only the first
1443 one. Reverse the order in which dependencies are stored so that
1444 when the second expansion reverses them again they appear in
1445 the makefile order (with some exceptions, see comments in
1446 the code). Remove the code that implements SySV-style automatic
1449 * file.c (snap_deps): Implement the second expansion and chopping
1450 of dependency lines for explicit rules.
1452 * implicit.c (struct idep): Define an auxiliary data type to hold
1453 implicit rule's dependencies after stem substitution and
1456 * implicit.c (free_idep_chain): Implement.
1458 * implicit.c (get_next_word): Implement helper function for
1459 parsing implicit rule's dependency lines into words taking
1460 into account variable expansion requests. Used in the stem
1463 * implicit.c (pattern_search): Implement the second expansion
1464 for implicit rules. Also fixes bug #12091.
1466 * commands.h (set_file_variables): Declare.
1467 * commands.c (set_file_variables): Remove static specifier.
1469 * dep.h (free_dep_chain): Declare.
1470 * misc.c (free_dep_chain): Implement.
1472 * variable.h (variable_expand_for_file): Declare.
1473 * expand.c (variable_expand_for_file): Remove static specifier.
1475 * make.h (strip_whitespace): Declare.
1476 * function.c (strip_whitespace): Remove static specifier.
1478 2005-02-26 Paul D. Smith <psmith@gnu.org>
1480 * main.c (main): Check for ferror() when reading makefiles from stdin.
1481 Apparently some shells in Windows don't close pipes properly and
1484 2005-02-24 Jonathan Grant <jg@jguk.org>
1486 * configure.in: Add MinGW configuration options, and extra w32 code
1488 * Makefile.am: Add MinGW configuration options, and extra w32 code
1490 * main.c: Determine correct program string (after last \ without .exe).
1491 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1493 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1494 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1495 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1496 environment support.
1498 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1500 * function.c (func_shell): When initializing error_prefix, check
1501 that reading file name is not null. This fixes long-standing
1502 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1504 2005-02-09 Paul D. Smith <psmith@gnu.org>
1506 * maintMakefile: Update the CVS download URL to simplify them.
1507 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1508 downloading the .texi files from Savannah now.
1510 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1512 * main.c (handle_non_switch_argument): Only add variables to
1513 command_variables if they're not already there: duplicate settings
1514 waste space and can be confusing to read.
1516 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1517 this header is never included by non-WINDOWS32 code, and it
1518 requires <config.h> to define which isn't always included first.
1520 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1521 testing MINGW32 versions.
1523 * main.c (log_working_directory): flush stdout to be sure the WD
1524 change is printed before any stderr messages show up.
1526 2005-02-01 Paul D. Smith <psmith@gnu.org>
1528 * maintMakefile (po_repo): Update the GNU translation site URL.
1530 2004-12-01 Paul D. Smith <psmith@gnu.org>
1532 * main.c (main): Change char* env_shell to struct variable shell_var.
1533 * variable.c (target_environment): Use new shell_var.
1535 2004-11-30 Paul D. Smith <psmith@gnu.org>
1537 * configure.in: The old way we avoided creating build.sh from
1538 build.sh.in before build.sh.in exists doesn't work anymore; we
1539 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1540 the help!). This also keeps automake from complaining.
1541 * Makefile.am (README): Add a dummy target so automake won't
1542 complain that this file doesn't exist when we checkout from CVS.
1543 * maintMakefile (.dep_segment): Rewrite this rule since newer
1544 versions of automake don't provide DEP_FILES.
1546 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1548 Implementation of `realpath' and `abspath' built-in functions.
1550 * configure.in: Check for realpath.
1551 * function.c (abspath): Return an absolute file name that does
1552 not contain any `.' or `..' components, nor repeated `/'.
1553 * function.c (func_abspath): For each name call abspath.
1554 * function.c (func_realpath): For each name call realpath
1555 from libc or delegate to abspath if realpath is not available.
1556 * doc/make.texi (Functions for File Names): Document new functions.
1557 * doc/make.texi (Quick Reference): Ditto.
1559 2004-11-28 Paul D. Smith <psmith@gnu.org>
1561 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1562 arguments. Fixes bug #10252.
1564 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1566 * main.c (main): Set SHELL to v_noexport by default. Remember the
1567 original environment setting of SHELL in the env_shell variable.
1568 * main.h: Export new env_shell variable.
1569 * variable.c (target_environment): If we find a v_noexport
1570 variable for SHELL, add a SHELL variable with the env_shell value.
1571 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1572 * doc/make.texi (Variables/Recursion): Ditto.
1574 2004-11-28 Paul D. Smith <psmith@gnu.org>
1576 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1577 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1578 Patch by Alessandro Vesely.
1580 2004-11-12 Paul D. Smith <psmith@gnu.org>
1582 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1583 the command line if it's inside a string.
1584 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1586 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1588 * function.c (func_lastword): New function: return last word
1589 from the list of words.
1590 * doc/make.texi: Document $(lastword ). Fix broken links in
1591 Quick Reference section.
1593 2004-10-06 Paul D. Smith <psmith@gnu.org>
1595 Apply patch from Alessandro Vesely, provided with bug # 9748.
1596 Fix use of tmpnam() to work with Borland C.
1598 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1599 construction of a temporary filename, and call new function
1600 create_batch_filename().
1601 (create_batch_filename) [WINDOWS32]: New function to create a
1604 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1606 * read.c (record_target_var): Expand simple pattern-specific
1608 * variable.c (initialize_file_variables): Do not expand simple
1609 pattern-specific variable.
1611 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1613 * remake.c (update_file_1): When rebuilding makefiles inherit
1614 dontcare flag from a target that triggered update.
1616 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1618 * variable.c (initialize_file_variables): Mark pattern-specific
1619 variable as a per-target and copy export status.
1621 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1623 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1625 * implicit.c (pattern_search): When considering an implicit rule's
1626 prerequisite check that it is actually a target rather then
1627 just an entry in the file hashtable.
1629 2004-09-21 Paul D. Smith <psmith@gnu.org>
1631 * read.c (readstring): Fix some logic errors in backslash handling.
1632 (eval): Remove some unnecessary processing in buffer handling.
1633 (record_target_var): Assert that parse_variable_definition() succeeded.
1634 Reported by: Markus Mauhart <qwe123@chello.at>.
1636 * misc.c: Removed the sindex() function. All instances of this
1637 function were trivially replaceable by the standard strstr()
1638 function, and that function will always have better (or certainly
1639 no worse) performance than the very simple-minded algorithm
1640 sindex() used. This can matter with complex makefiles.
1641 * make.h: Remove the prototype for sindex().
1642 * function.c (subst_expand): Convert sindex() call to strstr().
1643 This means we no longer need to track the TLEN value so remove that.
1644 (func_findstring): Convert sindex() to strstr().
1645 * commands.c (chop_commands): Convert sindex() calls to strstr().
1646 Suggested by: Markus Mauhart <qwe123@chello.at>.
1648 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1649 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1650 If SHELL is set to CMD.EXE then assume it's batch-mode and
1651 non-unixy. I wrote the code differently from the patch, though,
1652 to make it safer. This also resolves bug #9174.
1654 2004-09-20 Paul D. Smith <psmith@gnu.org>
1656 * expand.c (variable_expand_string): Modify to invoke
1657 patsubst_expand() instead of subst_expand(); the latter didn't
1658 handle suffix patterns correctly.
1659 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1660 was used only from variable_expand_string() and is no longer used
1662 (func_subst): Ditto, on call to subst_expand().
1663 (patsubst_expand): Require the percent pointers to point to the
1664 character after the %, not to the % itself.
1665 * read.c (record_files): New call criteria for patsubst_expand().
1666 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1667 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1669 2004-09-19 Paul D. Smith <psmith@gnu.org>
1671 * function.c (subst_expand): Fix a check in by_word: look for a
1672 previous blank if we're beyond the beginning of the string, not
1673 the beginning of the word.
1674 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1676 2004-05-16 Paul D. Smith <psmith@gnu.org>
1678 * remake.c (update_goal_chain): Change the argument specifying
1679 whether we're rebuilding makefiles to be a global variable,
1680 REBUILDING_MAKEFILES.
1681 (complain): Extract the code that complains about no rules to make
1682 a target into a separate function.
1683 (update_file_1): If we tried to rebuild a file during the makefile
1684 rebuild phase and it was dontcare, then no message was printed.
1685 If we then try to build the same file during the normal build,
1686 print a message this time.
1687 (remake_file): Don't complain about un-remake-able files when
1688 we're rebuilding makefiles.
1690 2004-05-11 Paul D. Smith <psmith@gnu.org>
1692 * job.c (construct_command_argv_internal): OS/2 patches from
1693 Andreas Buening <andreas.buening@nexgo.de>.
1695 2004-05-10 Paul D. Smith <psmith@gnu.org>
1697 * remake.c (update_file): Don't walk the double-colon chain unless
1698 this is a double-colon rule. Fix suggested by Boris Kolpackov
1699 <boris@kolpackov.net>.
1701 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1702 * readme.vms: New section describing OpenVMS support and issues.
1703 * default.c (default_variables): Add support for IA64.
1704 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1705 without some privilege aborts make with the error
1706 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1707 pressing Ctrl+Y and the input device is no terminal. The change
1708 catches this error and just continues.
1710 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1712 2004-04-25 Paul D. Smith <psmith@gnu.org>
1714 * commands.c (set_file_variables): Set $< properly in the face of
1715 order-only prerequisites.
1716 Patch from Boris Kolpackov <boris@kolpackov.net>
1718 2004-04-21 Bob Byrnes <byrnes@curl.com>
1720 * main.c (main): Notice failures to remake makefiles.
1722 2004-03-28 Paul D. Smith <psmith@gnu.org>
1724 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1726 * job.c: No default shell for RISC OS.
1727 (load_too_high): Hard-code the return to 1.
1728 (construct_command_argv_internal): No sh_chars or sh_cmds.
1729 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1731 2004-03-20 Paul D. Smith <psmith@gnu.org>
1733 * variable.c (do_variable_definition): Don't append from the
1734 global set if a previous non-appending target-specific variable
1735 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1738 * expand.c (reference_variable): Don't give up on variables with
1739 no value that have the target-specific append flag set: they might
1740 have a value after all. Reported by Oliver Schmidt
1741 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1742 <nikulin@dx1cmd.inp.nsk.su>.
1744 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1745 refer to absolute pathnames in directories that don't exist: some
1746 portion of the makefile could create those directories before we
1747 match the pattern. Fixes bugs #775 and #108.
1749 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1751 * main.c (main): Free makefile_mtimes if we have any.
1752 * README.W32.template: Update documentation for the current status
1753 of the MS-Windows port.
1754 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1755 environment variable is sometimes already defined which causes the
1757 * main.c (debug_signal_handler): Only define this function if
1758 SIGUSR1 is available.
1760 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1762 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1763 * README.OS2.template: Documentation updates.
1764 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1765 link line for safety.
1766 * maintMakefile (build.sh.in): Remove an extraneous ")".
1767 * job.c (child_execute_job): Close saved FDs.
1768 * job.c (exec_command) [OS/2]: exec_command(): If the command
1769 can't be exec'ed and if the shell is not Unix-sh, then try again
1770 with argv = { "cmd", "/c", ... }. Normally, this code is never
1771 reached for the cmd shell unless the command really doesn't exist.
1772 (construct_command_argv_internal) [OS/2]: The code for cmd
1773 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1774 The CMD builtin commands are case insensitive so use strcasecmp().
1776 2004-03-19 Paul D. Smith <psmith@gnu.org>
1778 * read.c (do_define): Re-order line counter increment so the count
1779 is accurate (we were losing one line per define). Reported by
1780 Dave Yost <Dave@Yost.com>.
1782 2004-03-06 Paul D. Smith <psmith@gnu.org>
1784 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1786 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1787 * misc.c (message,error,fatal): Ditto.
1788 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1789 * config.h.W32.template: Ditto.
1790 * config.h-vms.template: Ditto.
1791 * config.ami.template: Ditto.
1793 2004-03-04 Paul D. Smith <psmith@gnu.org>
1795 * README.template: Add a note about broken /bin/sh on SunOS
1796 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1798 * misc.c (message, error, fatal): Don't use "..." if we're using
1799 varargs. ansi2knr should handle this but it doesn't work: it
1800 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1801 done. On many systems (SunOS for example) va_dcl is a #define.
1802 So, force the use of the non-"..." version on pre-ANSI compilers.
1804 * maintMakefile (sign-dist): Create some rules to help automate
1805 the new GNU ftp upload method.
1807 2004-02-24 Paul D. Smith <psmith@gnu.org>
1809 * config.h.W32.template: Add HAVE_STDARG_H
1810 * config.h-vms.template: Ditto.
1811 * config.ami.template: Ditto.
1813 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1815 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1816 * build_w32.bat: Remove extra "+".
1818 2004-02-23 Paul D. Smith <psmith@gnu.org>
1820 * make.h: Create an UNUSED macro to mark unused parameters.
1821 * (many): Clean up warnings by applying UNUSED, fixing
1822 signed/unsigned incompatibilities, etc.
1824 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1826 * filedef.h: Name the command_state enumeration.
1827 * file.c (set_command_state): Use the enumeration in the function
1830 * configure.in: Explicitly set SET_MAKE to empty, to disable
1831 MAKE=make even when no make already exists. Fix bug #3823.
1833 2004-02-22 Paul D. Smith <psmith@gnu.org>
1835 * maintMakefile: Perl script to clean up all non-CVS files. Use
1836 it on all the subdirectories for the cvs-clean target.
1838 * main.c (decode_switches): Require non-empty strings for all our
1839 string command-line options. Fixes Debian bug # 164165.
1841 * configure.in: Check for stdarg.h and varargs.h.
1842 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1843 for printing messages.
1844 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1849 A number of patches for OS/2 support from Andreas Buening
1850 <andreas.buening@nexgo.de>:
1852 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1853 disable the SIGCHLD handler.
1854 (reap_children) [OS/2]: Remove special handling of job_rfd.
1855 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1856 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1857 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1858 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1859 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1862 2004-02-21 Paul D. Smith <psmith@gnu.org>
1864 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1865 <mail@kristov.de> reports that if process_begin() fails we don't
1866 handle the error condition correctly in all cases.
1867 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1868 to have a newline on the message.
1870 * job.c (construct_command_argv_internal): Add "test" to UNIX
1871 sh_cmds[]. Fixes Savannah bug # 7606.
1873 2004-02-04 Paul D. Smith <psmith@gnu.org>
1875 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1876 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1877 Hartmut Becker <Hartmut.Becker@hp.com>.
1879 2004-01-21 Paul D. Smith <psmith@gnu.org>
1881 * job.c (load_too_high): Implement an algorithm to control the
1882 "thundering herd" problem when using -l to control job creation
1883 via the load average. The system only recomputes the load once a
1884 second but we can start many jobs in a second. To solve this we
1885 keep track of the number of jobs started in the last second and
1886 apply a weight to try to guess what a correct load would be.
1887 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1888 Also fixes bug #4693.
1889 (reap_children): Decrease the job count for this second.
1890 (start_job_command): Increase the job count for this second.
1892 * read.c (conditional_line): Expand the text after ifn?def before
1893 checking to see if it's a single word. Fixes bug #7257.
1895 2004-01-09 Paul D. Smith <psmith@gnu.org>
1897 * file.c (print_file): Recurse to print all targets in
1898 double-colon rules. Fixes bug #4518, reported (with patch) by
1899 Andrew Chatham <chatham@google.com>.
1901 2004-01-07 Paul D. Smith <psmith@gnu.org>
1903 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1904 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1905 AC_FUNC_SETVBUF_REVERSED.
1907 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1908 (MAKE Variable): Fix Savannah bug #4898.
1910 * job.c (construct_command_argv_internal): Add "!" to the list of
1911 shell escape chars. POSIX sh allows it to appear before a
1912 command, to negate the exit code. Fixes bug #6404.
1914 * implicit.c (pattern_search): When matching an implicit rule,
1915 remember which dependencies have the ignore_mtime flag set.
1916 Original fix provided in Savannah patch #2349, by Benoit
1917 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1919 2003-11-22 Paul D. Smith <psmith@gnu.org>
1921 * README.W32.template (Outputs): Clarification on -j with
1922 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1925 2003-11-02 Paul D. Smith <psmith@gnu.org>
1927 * function.c (func_if): Strip all the trailing whitespace from the
1928 condition, then don't expand it. Fixed bug # 5798.
1930 * expand.c (recursively_expand_for_file): If we're expanding a
1931 variable with no file context, then use the variable's context.
1934 2003-10-21 Paul D. Smith <psmith@gnu.org>
1936 * main.c (log_working_directory): Add newlines to printf()s.
1938 * README.cvs: Add a note to ignore warnings during autoreconf.
1940 * maintMakefile (po_repo): Set a new URL for PO file updates.
1941 (get-config/config.guess get-config/config.sub): Get these files
1942 from the Savannah config project instead of ftp.gnu.org.
1944 2003-10-05 Paul Eggert <eggert@twinsun.com>
1946 * main.c (main): Avoid potential subscript error if environ has
1949 2003-08-22 Paul D. Smith <psmith@gnu.org>
1951 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1952 systems which don't yet implement the C89 standard :-/.
1954 2003-07-18 Paul D. Smith <psmith@gnu.org>
1956 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1957 [WINDOWS32]: Initialize hash.
1959 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1961 * dir.c (read_dirstream): Provide a workaround for broken versions of
1962 the MinGW dirent structure.
1964 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1966 * w32/include/dirent.h: Add __MINGW32__ filter.
1968 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1970 * make.h: Add global declaration of *make_host.
1971 * main.c (print_usage): Remove local declaration of *make_host.
1972 (print_version): Display "This program built for ..." after Copyright
1975 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1977 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1978 execution of "makeinfo --html make.texi".
1980 2003-04-30 Paul D. Smith <psmith@gnu.org>
1982 * build.template: Make some changes to maybe allow this script to
1983 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1985 * README.OS2.template: New file for OS/2 support. Original
1986 contributed by Andreas Buening.
1987 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1990 2003-04-19 Paul D. Smith <psmith@gnu.org>
1992 Fix bug #1405: allow a target to match multiple pattern-specific
1995 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1996 variable.c, where they've always belonged.
1997 * rule.h: Move the prototypes and struct pattern_var as well.
1998 * variable.c (initialize_file_variables): Invoke
1999 lookup_pattern_var() in a loop, until no more matches are found.
2000 If a match is found, create a new variable set for the target's
2001 pattern variables. Then merge the contents of each matching
2002 pattern variable set into the target's pattern variable set.
2003 (lookup_pattern_var): Change this function to be usable
2004 in a loop. It takes a starting position: if NULL, start at the
2005 beginning; if non-NULL, start with the pattern variable after that
2006 position, and return the next matching pattern.
2007 (create_pattern_var): Create a unique instance of
2008 pattern-specific variables for every definition in the makefile.
2009 Don't combine the same pattern together. This allows us to
2010 process the variable handling properly even when the same pattern
2011 is used multiple times.
2012 (parse_variable_definition): New function: break out the parsing
2013 of a variable definition line from try_variable_definition.
2014 (try_variable_definition): Call parse_variable_definition to
2016 (print_variable_data_base): Print out pattern-specific variables.
2017 * variable.h (struct variable): Remember when a variable is
2018 conditional. Also remember its flavor.
2019 (struct pattern_var): Instead of keeping a variable set, we just
2020 keep a single variable for each pattern.
2021 * read.c (record_target_var): Each pattern variable contains only a
2022 single variable, not a set, so create it properly.
2023 * doc/make.texi (Pattern-specific): Document the new behavior.
2025 2003-04-17 Paul D. Smith <psmith@gnu.org>
2027 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2028 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2029 file/directory naming rules for VMS so I can't tell whether this
2032 2003-04-09 Paul D. Smith <psmith@gnu.org>
2034 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2035 DOS-style pathnames: backslash separators and drive specifiers.
2037 2003-03-28 Paul D. Smith <psmith@gnu.org>
2039 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2040 the intermediate flag on all targets. Fixes bug #2515.
2042 2003-03-24 Paul D. Smith <psmith@gnu.org>
2044 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2045 Upgrade to autoconf 2.57 and automake 1.7.3.
2047 * job.c: More OS/2 changes from Andreas Buening.
2049 * file.c (print_file): Fix variable initialization.
2052 * remake.c (notice_finished_file):
2054 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2055 some calls (like readdir()) return NULL in valid situations
2056 without resetting errno. Fixes bug #2846.
2058 2003-02-25 Paul D. Smith <psmith@gnu.org>
2060 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2062 * job.c (_is_unixy_shell) [OS/2]: New function.
2063 Set default shell to /bin/sh.
2064 (reap_children): Close the job_rfd pipe here since we don't use a
2066 (set_child_handler_action_flags): define this to empty on OS/2.
2067 (start_job_command): Close the jobserver pipe and use
2068 child_execute_job() instead of fork/exec.
2069 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2070 rather than exec'ing, then reconfigure stdin/stdout.
2071 (exec_command): Rewrite to use spawn instead of exec. Return the
2074 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2075 in DOS. Handle the TEMP environment variable as in DOS. Don't
2076 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2077 use -j in DOS mode. Use child_execute_job() instead of
2080 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2083 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2084 prototypes that return values.
2086 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2088 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2089 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2091 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2094 2003-02-24 Paul D. Smith <psmith@gnu.org>
2096 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2097 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2098 (child_execute_job) [VMS]: Handle error status properly.
2099 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2101 * function.c (func_shell): Use EINTRLOOP() while reading from the
2102 subshell pipe (Fixes bug #2502).
2103 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2105 * main.c (main): Ditto.
2107 2003-01-30 Paul D. Smith <psmith@gnu.org>
2109 * read.c (eval): eval() was not fully reentrant, because the
2110 collapsed buffer was static. Change it to be an automatic
2111 variable so that eval() can be invoked recursively.
2113 (eval): Apply patch # 1022: fix memory reference error on long
2114 target-specific variable lines.
2115 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2117 * function.c (check_numeric): Combine the is_numeric() function
2118 into this function, since it's only called from one place.
2119 Constify this function. Have it print the incorrect string in the
2120 error message. Fixes bug #2407.
2121 (strip_whitespace): Constify.
2122 (func_if): Constify.
2123 * expand.c (expand_argument): Constify.
2125 2003-01-29 Paul D. Smith <psmith@gnu.org>
2127 Fix bug # 2169, also reported by other people on various systems.
2129 * make.h: Some systems, such as Solaris and PTX, do not fully
2130 implement POSIX-compliant SA_RESTART functionality; important
2131 system calls like stat() and readdir() can still fail with EINTR
2132 even if SA_RESTART has been set on the signal handler. So,
2133 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2134 EINTR for system calls which return -1 or 0 (NULL), respectively,
2136 Also, remove the old atomic_stat()/atomic_readdir() and
2137 HAVE_BROKEN_RESTART handling.
2139 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2141 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2142 * remake.c (touch_file): Ditto.
2144 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2145 * read.c (construct_include_path): Ditto.
2146 * remake.c (name_mtime): Ditto.
2147 * vpath.c (selective_vpath_search): Ditto.
2148 * dir.c (find_directory): Ditto.
2149 (local_stat): Ditto.
2150 (find_directory): Use ENULLLOOP() to wrap opendir().
2151 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2153 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2154 atomic_readdir() handling.
2156 2003-01-22 Paul D. Smith <psmith@gnu.org>
2158 * function.c (func_call): Fix Bug #1744. If we're inside a
2159 recursive invocation of $(call ...), mask any of the outer
2160 invocation's arguments that aren't used by this one, so that this
2161 invocation doesn't "inherit" them accidentally.
2163 2002-12-05 Paul D. Smith <psmith@gnu.org>
2165 * function.c (subst_expand): Valery Khamenia reported a
2166 pathological performance hit when doing substitutions on very
2167 large values with lots of words: turns out we were invoking
2168 strlen() a ridiculous number of times. Instead of having each
2169 call to sindex() call strlen() again, keep track of how much of
2170 the text we've seen and pass the length to sindex().
2172 2002-11-19 Paul D. Smith <psmith@gnu.org>
2174 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2177 2002-11-16 Paul D. Smith <psmith@gnu.org>
2179 * NMakefile.template (OBJS): Add hash.c object file.
2180 * SMakefile.template (srcs): Ditto.
2181 * Makefile.ami (objs): Ditto.
2182 * build_w32.bat: Ditto.
2184 * Makefile.DOS.template: Remove extra dependencies.
2186 2002-10-25 Paul D. Smith <psmith@gnu.org>
2188 * expand.c (install_variable_buffer): New function. Install a new
2189 variable_buffer context and return the previous one.
2190 (restore_variable_buffer): New function. Free the current
2191 variable_buffer context and put a previously saved one back.
2192 * variable.h: Prototypes for {install,restore}_variable_buffer.
2193 * function.c (func_eval): Push a new variable_buffer context
2194 before we eval, then restore the old one when we're done.
2197 * read.c (install_conditionals): New function. Install a new
2198 conditional context and return the previous one.
2199 (restore_conditionals): New function. Free the current
2200 conditional context and put a previously saved one back.
2201 (eval): Use the {install,restore}_conditionals for "include"
2203 (eval_buffer): Use {install,restore}_conditionals to preserve the
2204 present conditional state before we evaluate the buffer.
2207 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2209 (Recursion): Add a variable index entry for CURDIR.
2211 * README.cvs: Update to appropriate versions.
2212 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2213 don't need to copy loadavg.c: automake is smart enough to create
2214 it for me. Still have a bug in automake related to ansi2knr tho.
2216 2002-10-14 Paul D. Smith <psmith@gnu.org>
2218 * remake.c (notice_finished_file): Only touch targets if they have
2219 at least one command (as per POSIX). Resolve Bug #1418.
2221 * *.c: Convert to using ANSI C-style function definitions.
2222 * Makefile.am: Enable the ansi2knr feature of automake.
2223 * configure.in: ditto.
2225 2002-10-13 Paul D. Smith <psmith@gnu.org>
2227 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2228 for automatic variable values like $^, etc. In the case of very
2229 large lists of prerequisites this causes problems. Instead reuse
2230 a static buffer (resizeable) for each variable.
2232 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2233 target-specific variable definitions. Check for it and set an
2235 (record_target_var): Set the export field to v_export if the
2236 "exported" flag is set.
2237 * doc/make.texi (Target-specific): Document the ability to use
2240 * doc/make.texi: Change the name of the section on automatic
2241 variables from "Automatic" to "Automatic Variables". Added text
2242 clarifying the scope of automatic variables.
2244 2002-10-04 Paul D. Smith <psmith@gnu.org>
2246 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2248 (record_files): Ditto.
2250 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2251 the search for the '=' to only within the enclosing parens.
2253 2002-10-03 Paul D. Smith <psmith@gnu.org>
2255 Version 3.80 released.
2257 * dir.c: Change hash functions to use K&R function definition style.
2258 * function.c: Ditto.
2260 * variable.c: Ditto.
2262 Update to automake 1.7.
2264 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2265 (pdf): Remove this target as automake now provides one.
2267 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2269 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2271 * makefile.com: Updates for GNU make 3.80.
2272 * makefile.vms: Ditto.
2274 2002-09-23 Paul D. Smith <psmith@gnu.org>
2276 * read.c (enum make_word_type): Remove w_comment.
2277 (get_next_mword): Don't treat comment characters as special; where
2278 this function is used we will never see a comment (it's stripped
2279 before we get here) and treating comments specially means that
2280 targets like "foo\#bar" aren't handled properly.
2282 2002-09-18 Paul D. Smith <psmith@gnu.org>
2284 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2286 * read.c (eval): Expansion of arguments to export/unexport was
2287 ignoring all arguments after the first one. Change the algorithm
2288 to expand the whole line once, then parse the results.
2290 2002-09-17 Paul D. Smith <psmith@gnu.org>
2292 Fix Bug #940 (plus another bug I found while looking at this):
2294 * read.c (record_target_var): enter_file() will add a new entry if
2295 it's a double-colon target: we don't want to do that in this
2296 situation. Invoke lookup_file() and only enter_file() if it does
2297 not already exist. If the file we get back is a double-colon then
2298 add this variable to the "root" double-colon target.
2300 * variable.c (initialize_file_variables): If this file is a
2301 double-colon target but is not the "root" target, then initialize
2302 the root and make the root's variable list the parent of our
2305 2002-09-13 Paul D. Smith <psmith@gnu.org>
2307 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2309 * hash.c (round_up_2): Get rid of a warning.
2311 2002-09-12 Paul D. Smith <psmith@gnu.org>
2313 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2314 so it doesn't complain about getloadavg.c.
2316 * commands.c (set_file_variables): Make sure we always alloca() at
2317 least 1 character for the value of $? (for '\0').
2319 2002-09-11 Paul D. Smith <psmith@gnu.org>
2321 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2322 macro to use RESULT instead of the incorrect _RESULT_.
2324 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2325 and atomic_readdir(). We need to #include dirent.h to get this to
2327 * misc.c (atomic_readdir): Fix typos.
2329 2002-09-10 Paul D. Smith <psmith@gnu.org>
2331 * read.c (eval): Expand variable lists given to export and
2332 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2333 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2335 * doc/make.texi (Variables/Recursion): Document this.
2336 (Conditional Syntax): And here.
2338 2002-09-09 Paul D. Smith <psmith@gnu.org>
2340 * configure.in: Check for memmove().
2342 2002-09-07 Paul D. Smith <psmith@gnu.org>
2344 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2345 Michael Sterrett <msterret@coat.com> reports that while it has
2346 SA_RESTART, it does not work properly.
2348 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2349 that invokes stat() and loops to do it again if it returns EINTR.
2350 (atomic_readdir): Ditto, with readdir().
2352 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2353 and readdir() to atomic_stat() and atomic_readdir().
2355 2002-09-04 Paul D. Smith <psmith@gnu.org>
2357 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2358 reports that GNU make sometimes doesn't recognize that targets can
2359 be made, when directories can be created as prerequisites. He
2360 reports that changing the order of predicates in the DEP->changed
2361 flag test so that lookup_file() is always performed, solves this
2364 2002-08-08 Paul D. Smith <psmith@gnu.org>
2366 * configure.in: Require a newer version of gettext.
2368 * misc.c (perror_with_name): Translate the format string (for
2369 right-to-left language support).
2370 (pfatal_with_name): Ditto.
2372 * main.c: Create a static array of strings to store the usage
2373 text. This is done to facilitate translations.
2374 (struct command_switch): Remove argdesc and description fields.
2375 (switches): Remove values for obsolete fields.
2376 (print_usage): Print each element of the usage array.
2378 * hash.c: Change function definitions to be K&R style.
2380 2002-08-02 Paul D. Smith <psmith@gnu.org>
2382 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2383 this one because it's too hard to get right. We'll look at it for
2385 * main.c (main): Don't create the .TARGETS variable.
2386 * variable.c (handle_special_var): Don't handle .TARGETS.
2388 2002-08-01 Paul D. Smith <psmith@gnu.org>
2390 * main.c (switches): Add a new option, -B (--always-make). If
2391 specified, make will rebuild all targets that it encounters even
2392 if they don't appear to be out of date.
2393 (always_make_flag): New flag.
2394 * make.h: Extern always_make_flag.
2395 * remake.c (update_file_1): Check always_make_flag; if it's set we
2396 will always rebuild any target we can, even if none of its
2397 prerequisites are newer.
2400 * doc/make.texi (Shell Function): Make it clear that make
2401 variables marked as "export" are not passed to instances of the
2404 Add new introspection variable .VARIABLES and .TARGETS.
2406 * variable.c (handle_special_var): New function. If the variable
2407 reference passed in is "special" (.VARIABLES or .TARGETS),
2408 calculate the new value if necessary. .VARIABLES is handled here:
2409 walk through the hash of defined variables and construct a value
2410 which is a list of the names. .TARGETS is handled by
2411 build_target_list().
2412 (lookup_variable): Invoke handle_special_var().
2413 * file.c (build_target_list): Walk through the hask of known files
2414 and construct a list of the names of all the ones marked as
2416 * main.c (main): Initialize them to empty (and as simple variables).
2417 * doc/make.texi (Special Variables): Document them.
2418 * NEWS: Mention them.
2420 * variable.h (struct variable): Add a new flag "exportable" which
2421 is true if the variable name is valid for export.
2422 * variable.c (define_variable_in_set): Set "exportable" when a new
2423 variable is defined.
2424 (target_environment): Use the "exportable" flag instead of
2425 re-checking the name here... an efficiency improvement.
2427 2002-07-31 Paul D. Smith <psmith@gnu.org>
2429 * config.h-vms.template: Updates to build on VMS. Thanks to
2430 Brian_Benning@aksteel.com for helping verify the build.
2431 * makefile.com: Build the new hash.c file.
2432 * hash.h: Use strcpmi(), not stricmp(), in the
2433 HAVE_CASE_INSENSITIVE_FS case.
2435 2002-07-30 Paul D. Smith <psmith@gnu.org>
2437 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2438 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2439 Reported by <Brian_Benning@aksteel.com>.
2441 2002-07-10 Paul D. Smith <psmith@gnu.org>
2443 * variable.c (pop_variable_scope): Remove variable made unused by
2444 new hash infrastructure.
2445 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2446 comparisons as well as name comparisons.
2447 * variable.h: Add a prototype for new hash_init_function_table().
2448 * file.c (lookup_file): Remove variables made unused by new hash
2450 * dir.c (directory_contents_hash_2): Missing return of hash value.
2451 (dir_contents_file_exists_p): Remove variables made unused by new
2452 hash infrastructure.
2455 Installed Greg McGary's integration of the hash functions from the
2456 GNU id-utils package:
2458 2002-07-10 Greg McGary <greg@mcgary.org>
2460 * scripts/functions/filter-out: Add literals to to the
2461 pattern space in order to add complexity, and trigger
2462 use of an internal hash table. Fix documentation strings.
2463 * scripts/targets/INTERMEDIATE: Reverse order of files
2464 passed to expected `rm' command.
2466 2002-07-10 Greg McGary <greg@mcgary.org>

2558 2002-07-10 Paul D. Smith <psmith@gnu.org>
2560 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2561 prerequisite list. A real SysV make will expand the entire
2562 prerequisites list _twice_: we don't do that as it's a big
2563 backward-compatibility problem. We only replace those specific
2566 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2567 references left in the list of prerequisites. Check for .POSIX as
2568 we record targets, so we can disable non-POSIX behavior while
2569 reading makefiles as well as running them.
2570 (eval): Check the prerequisite list to see if we have anything
2571 that looks like a SysV prerequisite variable reference.
2573 2002-07-09 Paul D. Smith <psmith@gnu.org>
2575 * doc/make.texi (Prerequisite Types): Add a new section describing
2576 order-only prerequisites.
2578 * read.c (uniquize_deps): If we have the same file as both a
2579 normal and order-only prereq, get rid of the order-only prereq,
2580 since the normal one supersedes it.
2582 2002-07-08 Paul D. Smith <psmith@gnu.org>
2584 * AUTHORS: Added Greg McGary to the AUTHORS file.
2585 * NEWS: Blurbed order-only prerequisites.
2586 * file.c (print_file): Show order-only deps properly when printing
2589 * maintMakefile: Add "update" targets for wget'ing the latest
2590 versions of various external files. Taken from Makefile.maint in
2593 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2594 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2596 2002-07-07 Paul D. Smith <psmith@gnu.org>
2598 * po/*.po: Remove. We'll use wget to retrieve them at release
2601 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2602 rather than a shell you get an exception. Make sure we look up
2603 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2605 * remake.c (notice_finished_file): Fix handling of -t flag.
2606 Patch provided by Henning Makholm <henning@makholm.net>.
2608 * implicit.c (pattern_search): Some systems apparently run short
2609 of stack space, and using alloca() in this function caused an
2610 overrun. I modified it to use xmalloc() on the two variables
2611 which seemed like they might get large. Fixes Bug #476.
2613 * main.c (print_version): Update copyright notice to conform with
2615 (print_usage): Update help output.
2617 * function.c (func_eval): Create a new make function, $(eval
2618 ...). Expand the arguments, put them into a buffer, then invoke
2619 eval_buffer() on the resulting string.
2620 (func_quote): Create a new function, $(quote VARNAME). Inserts
2621 the value of the variable VARNAME without expanding it any
2624 * read.c (struct ebuffer): Change the linebuffer structure to an
2625 "eval buffer", which can be either a file or a buffer.
2626 (eval_makefile): Move the code in the old read_makefile() which
2627 located a makefile into here: create a struct ebuffer with that
2628 information. Have it invoke the new function eval() with that
2630 (eval_buffer): Create a new function that creates a struct ebuffer
2631 that holds a string buffer instead of a file. Have it invoke
2632 eval() with that ebuffer.
2633 (eval): New function that contains the guts of the old
2634 read_makefile() function: this function parses makefiles. Obtains
2635 data to parse from the provided ebuffer. Some modifications to
2636 make the flow of the function cleaner and clearer. Still could
2637 use some work here...
2638 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2639 contents of the define/endef variable from the ebuffer.
2640 (readstring): Read the next line from a string-style ebuffer.
2641 (readline): Read the next line from an ebuffer. If it's a string
2642 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2645 * dep.h (eval_buffer): Prototype eval_buffer();
2647 * variable.c (do_variable_definition): Make sure that all
2648 non-target-specific variables are registered in the global set.
2649 If we're invoked from an $(eval ...) we might be inside a $(call
2650 ...) or other function which has pushed a variable scope; we still
2651 want to define our variables from evaluated makefile code in the
2654 2002-07-03 Greg McGary <greg@mcgary.org>
2656 * dep.h (struct dep) [ignore_mtime]: New member.
2657 [changed]: convert to a bitfield.
2658 * implicit.c (pattern_search): Zero ignore_mtime.
2659 * main.c (main, handle_non_switch_argument): Likewise.
2660 * rule.c (convert_suffix_rule): Likewise.
2661 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2662 (read_makefile): Parse '|' in prerequisite list.
2663 (uniquize_deps): Consider ignore_mtime when comparing deps.
2664 * remake.c (update_file_1, check_dep): Don't force remake for
2665 dependencies that have d->ignore_mtime.
2666 * commands.c (FILE_LIST_SEPARATOR): New constant.
2667 (set_file_variables): Don't include a
2668 prerequisite in $+, $^ or $? if d->ignore_mtime.
2671 2002-06-18 Paul D. Smith <psmith@gnu.org>
2673 * make.texinfo: Updates for next revision. New date/rev/etc.
2674 Recreate all Info menus. Change license on the manual to the GNU
2675 Free Documentation License. A number of typos.
2676 (Variables Simplify): Don't use "-" before it's defined.
2677 (Automatic Prerequisites): Rewrite the target example to work
2678 properly if the compile fails. Remove incorrect comments about
2679 how "set -e" behaves.
2680 (Text Functions): Move the "word", "wordlist", "words", and
2681 "firstword" functions here, from "File Name Functions".
2682 * make-stds.texi: Update from latest GNU version.
2683 * fdl.texi: (created) Import the latest GNU version.
2685 2002-06-06 Paul D. Smith <psmith@gnu.org>
2687 * variable.c (do_variable_definition): New function: extract the
2688 part of try_variable_definition() that actually sets the value
2689 into a separate function.
2690 (try_variable_definition): Call do_variable_definition() after
2691 parsing the variable definition string.
2692 (define_variable_in_set): Make the name argument const.
2694 * variable.h (enum variable_flavor): Make public.
2695 (do_variable_definition): Create prototype.
2697 * read.c (read_all_makefiles): Create a new built-in variable,
2699 (read_makefile): Add each makefile read in to this variable value.
2701 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2703 * Makefile.DOS.template: Tweak according to changes in the
2704 distribution. Add back the dependencies of *.o files.
2706 * configh.dos.template: Synchronize with config.h.in.
2708 2002-05-09 Paul D. Smith <psmith@gnu.org>
2710 * file.c (file_timestamp_now): Use K&R function declaration.
2712 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2713 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2714 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2715 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2716 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2717 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2718 nlist.n_name is a pointer rather than an array.
2720 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2721 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2722 * configure.in: Use it instead of the old version.
2724 * main.c (main): Prefer setvbuf() to setlinebuf().
2726 2002-05-08 Paul D. Smith <psmith@gnu.org>
2728 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2729 (loadavg_LDADD): Ditto.
2731 2002-04-29 Paul D. Smith <psmith@gnu.org>
2733 * expand.c (recursively_expand_for_file): Rename
2734 recursively_expand() to recursively_expand_for_file() and provide
2735 an extra argument, struct file. If the argument is provided, set
2736 the variable scope to that of the file before expanding.
2737 * variable.h (recursively_expand): Make this a macro that invokes
2738 recursively_expand_for_file() with a NULL file pointer.
2739 * variable.c (target_environment): Call the renamed function and
2740 provide the current file context.
2741 Fixes Debian bug #144306.
2743 2002-04-28 Paul D. Smith <psmith@gnu.org>
2745 Allow $(call ...) user-defined variables to be self-referencing
2746 without throwing an error. Allows implementation of transitive
2747 closures, among other possibly useful things.
2748 Requested by: Philip Guenther <guenther@sendmail.com>
2750 * variable.h (struct variable): Add a new field: exp_count, and
2751 new macros to hold its size and maximum value.
2752 (warn_undefined): Make this a macro.
2753 * variable.c (define_variable_in_set): Initialize it.
2754 * expand.c (recursively_expand): If we detect recursive expansion
2755 of a variable, check the exp_count field. If it's greater than 0
2756 allow the recursion and decrement the count.
2757 (warn_undefined): Remove this (now a macro in variable.h).
2758 * function.c (func_call): Before we expand the user-defined
2759 function, modify its exp_count field to contain the maximum
2760 number of recursive calls we'll allow. After the call, reset it
2763 2002-04-21 Paul D. Smith <psmith@gnu.org>
2765 Modified to use latest autoconf (2.53), automake (1.6.1), and
2766 gettext (0.11.1). We're using gettext's new "external" support,
2767 to avoid including libintl source with GNU make.
2769 * README.cvs: New file. Explain how to build GNU make from CVS.
2771 * configure.in: Modify checking for the system glob library.
2772 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2773 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2774 etc. will manage it correctly). Set an automake conditional
2775 USE_LOCAL_GLOB to decide whether to compile the glob library.
2777 * getloadavg.c (main): Include make.h in the "TEST" program to
2780 * Makefile.am: Remove special rules for loadavg. Replace them
2781 with Automake capabilities for building extra programs.
2783 * signame.c: This file does nothing if the system provide
2784 strsignal(). If not, it implements strsignal(). If the system
2785 doesn't define sys_siglist, then we make our own; otherwise we use
2787 * signame.h: Removed.
2789 * main.c (main): No need to invoke signame_init(). Update copyright.
2791 * ABOUT-NLS: Removed.
2792 * gettext.c: Removed.
2793 * gettext.h: Get a simplified copy from the gettext package.
2795 * i18n/*.po: Moved to po/.
2798 * config/*: Created. Contains package configuration helper files.
2799 * config.guess, config.sub: Moved to config directory.
2801 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2802 Rework to use new-style autoconf features. Use the "external"
2803 mode for gettext. Make the build.sh config file conditional on
2804 whether build.sh.in exists, to avoid autoconf errors.
2805 * acinclude.m4: Removed almost all macros as being obsolete.
2806 Rewrote remaining macros to use AC_DEFINE.
2807 * acconfig.h: Removed.
2809 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2810 conditional to handle customs support. Remove special handling
2813 2002-04-20 Paul D. Smith <psmith@gnu.org>
2815 * function.c (func_call): Don't mark the argument variables $1,
2816 etc. as recursive. They've already been fully expanded so
2817 there's no need to do it again, and doing so strips escaped $'s.
2818 Reported by Sebastian Glita <glseba@yahoo.com>.
2820 * remake.c (notice_finished_file): Walk through double-colon
2821 entries via the prev field, not the next field!
2822 Reported by Greg McGary <greg@mcgary.org>.
2824 * main.c (main): If the user specifies -q and asks for a specific
2825 target which is a makefile, we got an assert. In that case it
2826 turns out we should continue normally instead.
2828 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2830 * i18n/he.po: Installed a new translation.
2832 2002-01-07 Paul D. Smith <psmith@gnu.org>
2834 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2836 2001-12-04 Paul D. Smith <psmith@gnu.org>
2838 * i18n/ja.po: Installed an updated translation.
2840 2001-09-06 Paul Eggert <eggert@twinsun.com>
2842 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2843 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2845 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2847 (main): Get rid of any avoidable limit on stack size.
2849 2001-09-04 Paul D. Smith <psmith@gnu.org>
2851 * i18n/da.po: Installed an updated translation.
2853 2001-08-03 Paul D. Smith <psmith@gnu.org>
2855 * i18n/fr.po: Installed an updated translation.
2856 Resolves Debian bug #106720.
2858 2001-06-13 Paul D. Smith <psmith@gnu.org>
2860 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2863 2001-06-11 Paul D. Smith <psmith@gnu.org>
2865 * i18n/ko.po: Installed a new translation.
2867 2001-05-06 Paul D. Smith <psmith@gnu.org>
2869 Modify the EINTR handling.
2871 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2872 the way in which we manage the file descriptor/signal handler race
2873 trap to be more efficient.
2875 2001-05-06 Paul Eggert <eggert@twinsun.com>
2877 Restart almost all system calls that are interrupted, instead
2878 of worrying about EINTR. The lone exception is the read() for
2881 * configure.in (HAVE_SA_RESTART): New macro.
2882 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2883 * main.c (main): Use SA_RESTART instead of the old,
2884 nonstandard SA_INTERRUPT.
2886 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2887 * main.c (bsd_signal): New function or macro,
2888 if the implementation doesn't supply it.
2889 (The bsd_signal function will be in POSIX 1003.1-200x.)
2890 (HANDLESIG): Remove.
2891 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2893 * make.h (EINTR_SET): Remove.
2894 (SA_RESTART): New macro.
2896 * arscan.c (ar_member_touch): Don't worry about EINTR.
2897 * function.c (func_shell): Likewise.
2898 * job.c (reap_children, free_child, new_job): Likewise.
2899 * main.c (main): Likewise.
2900 * remake.c (touch_file, name_mtime): Likewise.
2902 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2903 if fstat failed with errno!=EINTR, the error was ignored.
2905 * job.c (set_child_handler_action_flags): New function.
2906 (new_job): Use it to temporarily clear the SIGCHLD action flags
2907 while reading the token.
2909 2001-05-02 Paul D. Smith <psmith@gnu.org>
2911 * job.c (start_job_command): Don't add define/endef per-line flags
2912 to the top-level flags setting.
2914 2001-04-03 Paul D. Smith <psmith@gnu.org>
2916 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2917 bit on error, so check for odd return values, not non-0 return
2919 (VMS_get_member_info): Calculate the timezone differences correctly.
2920 Reported by John Fowler <jfowler@nyx.net>.
2923 2001-03-14 Paul D. Smith <psmith@gnu.org>
2925 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2926 value before invoking define_variable().
2927 Reported by John Fowler <jfowler@nyx.net>.
2929 2001-02-07 Paul D. Smith <psmith@gnu.org>
2931 * read.c (record_target_var): If we reset the variable due to a
2932 command-line variable setting overriding it, turn off the "append"
2935 2001-01-17 Paul D. Smith <psmith@gnu.org>
2937 * variable.c (lookup_variable) [VMS]: When getting values from the
2938 environment, allocate enough space for the _value_ plus escapes,
2939 not enough space for the name plus escapes :-/.
2940 Reported by John Fowler <jfowler@nyx.net>.
2942 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2943 warnings that make generates, so it doesn't look like an error.
2944 Reported by Karl Berry <karl@gnu.org>.
2947 Fix for PR/2020: Rework appended target-specific variables. I'm
2948 fairly confident this algorithm is finally correct.
2950 * expand.c (allocated_variable_append): Rewrite. Instead of
2951 expanding each appended variable then adding all the expanded
2952 strings together, we append all the unexpanded values going up
2953 through the variable set contexts, then expand the final result.
2954 This behaves just like non-target-specific appended variable
2955 values, while the old way didn't in various corner cases.
2956 (variable_append): New function: recursively append the unexpanded
2957 value of a variable, walking from the outermost variable scope to
2959 * variable.c (lookup_variable): Remove the code that looked up the
2960 variable set list if the found variable was "append". We don't
2962 (lookup_variable_in_set): Make this non-static so we can use it
2964 (try_variable_definition): Use lookup_variable_in_set() rather
2965 than faking out current_variable_set_list by hand (cleanup).
2966 * variable.h: Add a prototype for the now non-static
2967 lookup_variable_in_set().
2969 2000-11-17 Paul D. Smith <psmith@gnu.org>
2971 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2972 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2973 before throwing a fit.
2975 2000-11-17 Paul D. Smith <psmith@gnu.org>
2977 * read.c (readline): CRLF calculations had a hole, if you hit the
2978 buffer grow scenario just right. Reworked the algorithm to avoid
2979 the need for len or lastlen at all. Problem description with
2980 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2982 2000-10-24 Paul D. Smith <psmith@gnu.org>
2984 * gettext.c (SWAP): Declare this with the prototype, otherwise
2985 some systems don't work (non-32-bit? Reported for Cray T3E).
2986 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2988 2000-10-05 Paul D. Smith <psmith@gnu.org>
2990 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2991 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2993 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2995 2000-09-22 Paul D. Smith <psmith@gnu.org>
2997 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2998 parts of the real gettext.h here, and we expect to really include
2999 the real gettext.h later. If we keep this #define, it's ignored.
3001 2000-09-21 Paul D. Smith <psmith@gnu.org>
3003 * main.c (log_working_directory): Rework the text to use complete
3004 sentences, to make life simpler for the translators.
3006 2000-08-29 Paul D. Smith <psmith@gnu.org>
3008 * file.c (remove_intermediates): Print a debug message before we
3009 remove intermediate files, so the user (if she uses -d) knows
3012 2000-08-21 Paul D. Smith <psmith@gnu.org>
3014 * variable.c (try_variable_definition): Change how we handle
3015 target-specific append variable defns: instead of just setting the
3016 value, expand it as an append _but_ only within the current
3017 target's context. Otherwise we lose all but the last value if the
3018 variable is appended more than once within the current target
3019 context. Fixes PR/1831.
3021 2000-08-16 Paul D. Smith <psmith@gnu.org>
3023 * function.c (func_shell): Nul-terminate the buffer before
3024 printing an exec error message (just in case it's not!).
3025 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3027 2000-07-25 Paul D. Smith <psmith@gnu.org>
3029 * job.c (construct_command_argv_internal): Add "~" to the list of
3030 sh_chars[] which disallow optimizing out the shell call.
3032 2000-07-23 Paul Eggert <eggert@twinsun.com>
3034 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3035 supersedes --disable-nsec-timestamps.
3036 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3037 * README: Remove --disable-nsec-timestamps.
3039 * filedef.h (struct file.low_resolution_time): New member.
3040 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3041 * remake.c (update_file_1):
3042 Avoid spurious rebuilds due to low resolution time stamps,
3043 generalizing the earlier code that applied only to archive members.
3044 (f_mtime): Archive members always have low resolution time stamps.
3046 * configure.in: Remove --disable-nsec-timestamps, as this has
3047 been superseded by .LOW_RESOLUTION_TIME.
3049 2000-07-23 Paul Eggert <eggert@twinsun.com>
3051 * configure.in (enable_nsec_timestamps): Renamed from
3052 make_cv_nsec_timestamps, since enable/disable options
3053 shouldn't be cached.
3055 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3056 and Paul Eggert <eggert@twinsun.com>
3058 * file.c (file_timestamp_now):
3059 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3060 so that clock_gettime is not linked unless needed.
3062 * filedef.h (FILE_TIMESTAMP_HI_RES):
3063 Remove definition; "configure" now does this.
3065 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3066 to before high resolution file timestamp check,
3067 since that check now uses uintmax_t.
3068 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3069 high resolution file timestamps.
3070 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3071 so that we don't link in clock_gettime unnecessarily.
3073 2000-07-17 Paul D. Smith <psmith@gnu.org>
3075 * i18n/ja.po: New version of the translation file.
3077 2000-07-07 Paul D. Smith <psmith@gnu.org>
3079 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3080 the offset calculation.
3081 (name_mtime): Replace EINTR test with EINTR_SET macro.
3083 2000-07-07 Paul Eggert <eggert@twinsun.com>
3087 * remake.c (update_file_1):
3088 Avoid spurious rebuilds of archive members due to their
3089 timestamp resolution being only one second.
3090 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3091 the clock's resolution being lower than file timestamps'.
3092 When warning about future timestamps, report only the discrepancy,
3093 not the absolute value of the timestamp and the current time.
3095 * file.c (file_timestamp_now): New arg RESOLUTION.
3096 * filedef.h (file_timestamp_now): Likewise.
3097 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3099 2000-07-05 Paul D. Smith <psmith@gnu.org>
3101 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3102 to listp. Fixes PR/1793.
3104 2000-06-26 Paul Eggert <eggert@twinsun.com>
3106 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3108 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3110 * remake.c (f_mtime): Remove unused var memtime.
3112 2000-06-25 Martin Buchholz <martin@xemacs.org>
3114 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3115 Ran spell-check on make.texinfo.
3117 2000-06-23 Paul D. Smith <psmith@gnu.org>
3119 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3120 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3121 * make.h: Define these macros.
3123 * Version 3.79.1 released.
3125 * configure.in: Add a new option, --disable-nsec-timestamps, to
3126 avoid using sub-second timestamps on systems that support it. It
3127 can lead to problems, e.g. if your makefile relies on "cp -p".
3128 * README.template: Document the issue with "cp -p".
3130 * config.guess, config.sub: Updated.
