64 (.SUFFIXES): Add .html.
66 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
68 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
69 HAVE_DECL_SYS_SIGLIST.

99 2007-10-12 Eli Zaretskii <eliz@gnu.org>
101 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
102 a more complex value than a simple shell: if it's not a default

158 * read.c (eval): Remove the cmd_prefix characters from the command
159 scripts here, so they're not stored in the commands array at all,
160 rather than waiting and stripping them out during command construction.
161 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
163 2007-08-15 Paul Smith <psmith@gnu.org>

229 Dave Korn <dave.korn@artimi.com>
231 2007-05-08 Paul Smith <psmith@gnu.org>
233 Fix Savannah bug #19656:
235 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
237 * make.h: Change all case-insensitive string compares to use
238 strcasecmp() (from POSIX). If we don't have that but do have one
239 of the others, define strcasecmp to be one of those instead. If
240 we don't have any, declare a prototype for our own version.
242 * misc.c (strcasecmp): Use this if we can't find any native
243 case-insensitive string comparison function.
244 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
245 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
247 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
248 strcasecmp() instead of stricmp().
249 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
250 instead of strcmpi().
251 * acinclude.m4: Remove the strcasecmp() check from here.
253 2007-03-21 Paul Smith <psmith@gnu.org>
255 * configure.in: Don't turn on case-insensitive file system support
256 if --disable-... is given. Fixes Savannah bug #19348.
258 2007-03-19 Paul Smith <psmith@gnu.org>
260 * ALL: Use the strcache for all file name strings, or other
261 strings which we will never free. The goal is to save memory by
262 avoiding duplicate copies of strings. However, at the moment this
263 doesn't save much memory in most situations: due to secondary
264 expansion we actually save prerequisite lists twice (once before
265 the secondary expansion, and then again after it's been parsed
266 into individual file names in the dep list). We will resolve this
267 in a future change, by doing the parsing up-front for targets
268 where secondary expansion is not set.
270 Moving things into the strcache also allows us to use const
271 pointers in many more places.
273 2007-01-03 Paul Smith <psmith@gnu.org>
275 * make.h (ENULLLOOP): Reset errno after each failed invocation of
276 the function, not just the first. Fixes Savannah bug #18680.
278 2006-11-18 Paul Smith <psmith@gnu.org>
280 * strcache.c (strcache_add_len): Don't allocate a new buffer
281 unless the string is not already nil-terminated. Technically this
282 is a violation of the standard, since we may be passed an array
283 that is not long enough to test one past. However, in make this
284 is never true since we only use nil-terminated strings or
287 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
289 * main.c: New global cmd_prefix, defaults to '\t'.
290 * job.c (construct_command_argv_internal): Use cmd_prefix instead
294 (dir_contents_file_exists_p): Check for an error return from
295 readdir(), just in case.
297 * commands.c: Constified.
298 * default.c: Constified.
299 * expand.c: Constified.
300 * function.c: Partial constification.
301 * variable.c: Partial constification.
302 * vmsify.c: Constification. Hard to test this but I hope I didn't

307 2006-11-16 Eli Zaretskii <eliz@gnu.org>
309 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
310 backslashes and drive letters as absolute.
312 2006-10-22 Paul Smith <psmith@gnu.org>
314 * main.c (struct command_switch): Use const and void*.
316 2006-10-21 Paul Smith <psmith@gnu.org>
319 * arscan.c: Constified.
321 2006-09-30 Paul Smith <psmith@gnu.org>
323 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
324 point to lastword since the example was updated.
325 Fixes Savannah bug #16304.
326 (Secondary Expansion): Correct example description.
327 Fixes Savannah bug #16468.
328 (Makefile Contents): Clarify that comments cannot appear within
329 variable references or function calls.
330 Fixes Savannah bug #16577.
331 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
332 Fixes Savannah bug #17701.
333 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

377 * README.cvs: Add a reminder to notify the GNU translation robot.
379 * doc/make.texi: Change @direcategory (requested by Karl Berry).
381 2006-04-20 Paul D. Smith <psmith@gnu.org>
383 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
384 that don't have extended grep.
385 (cvsclean): Use $(PERL) instead of perl.

391 * expand.c, implicit.c, main.c, read.c: Rename variables so that
392 inner-scope variables don't mask outer-scope variables.

519 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
520 listed non-existent files as changed. Turns out there's a bug in
521 the Linux kernel builds which means that this change causes
522 everything to rebuild every time. We will re-introduce this fix
523 in the next release, to give them time to fix their build system.
524 Fixes Savannah bug #16002.
525 Introduces Savannah bug #16051.

544 * commands.c (set_file_variables): Realloc, not malloc, the static
545 string values to avoid memory leaks.
547 * expand.c (recursively_expand_for_file): Only set reading_file to
548 an initialized value.
550 * implicit.c (pattern_search): We need to make a copy of the stem
551 if we get it from an intermediate dep, since those get freed.

560 * job.c (construct_command_argv_internal): Fix last change.
562 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
563 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
564 the calls to _beginthreadex.
566 * expand.c (recursively_expand_for_file): Initialize `save' to
567 prevent compiler warnings.
569 2006-02-18 Eli Zaretskii <eliz@gnu.org>
571 * job.c (construct_command_argv_internal): Don't create a temporary
572 script/batch file if we are under -n. Call _setmode to switch the
573 script file stream to text mode.
575 2006-02-17 Paul D. Smith <psmith@gnu.org>
577 * variable.c (merge_variable_set_lists): Don't try to merge the
578 global_setlist. Not only is this useless, but it can lead to
579 circularities in the linked list, if global_setlist->next in one
580 list gets set to point to another list which also ends in
582 Fixes Savannah bug #15757.
584 2006-02-15 Paul D. Smith <psmith@gnu.org>
586 Fix for Savannah bug #106.
588 * expand.c (expanding_var): Keep track of which variable we're
589 expanding. If no variable is being expanded, it's the same as
591 * make.h (expanding_var): Declare it.
592 * expand.c (recursively_expand_for_file): Set expanding_var to the
593 current variable we're expanding, unless there's no file info in
594 it (could happen if it comes from the command line or a default
595 variable). Restore it before we exit.
596 * expand.c (variable_expand_string): Use the expanding_var file
597 info instead of the reading_file info.
598 * function.c (check_numeric): Ditto.
600 (func_wordlist): Ditto.
602 (expand_builtin_function): Ditto.
603 (handle_function): Ditto.
605 2006-02-14 Paul D. Smith <psmith@gnu.org>
607 * read.c (eval): Even if the included filenames expands to the
608 empty string we still need to free the allocated buffer.
610 * implicit.c (pattern_search): If we allocated a variable set for
611 an impossible file, free it.
612 * variable.c (free_variable_set): New function.
613 * variable.h: Declare it.
615 * read.c (read_all_makefiles): Makefile names are kept in the
616 strcache, so there's never any need to alloc/free them.
619 * main.c (main): Add "archives" to the .FEATURES variable if
620 archive support is enabled.
621 * doc/make.texi (Special Variables): Document it.
623 2006-02-13 Paul D. Smith <psmith@gnu.org>
625 * implicit.c (pattern_search): Add checking for DOS pathnames to
626 the pattern rule target LASTSLASH manipulation.
627 Fixes Savannah bug #11183.
629 2006-02-11 Paul D. Smith <psmith@gnu.org>
631 * (ALL FILES): Updated copyright and license notices.
633 2006-02-10 Paul D. Smith <psmith@gnu.org>
635 A new internal capability: the string cache is a read-only cache
636 of strings, with a hash table interface for fast lookup. Nothing
637 in the cache will ever be freed, so there's no need for reference
638 counting, etc. This is the beginning of a full solution for
639 Savannah bug #15182, but for now we only store makefile names here.
641 * strcache.c: New file. Implement a read-only string cache.
642 * make.h: Add prototypes for new functions.
643 * main.c (initialize_global_hash_tables): Initialize the string cache.
644 (print_data_base): Print string cache stats.
645 * read.c (eval_makefile): Use the string cache to store makefile
646 names. Rewrite the string allocation to be sure we free everything.
648 2006-02-10 Eli Zaretskii <eliz@gnu.org>
650 * dir.c (dir_contents_file_exists_p): Don't opendir if the
651 directory time stamp didn't change, except on FAT filesystems.
652 Suggested by J. David Bryan <jdbryan@acm.org>.
654 2006-02-09 Paul D. Smith <psmith@gnu.org>
656 * function.c (func_or): Implement a short-circuiting OR function.
657 (func_and): Implement a short-circuiting AND function.
658 (function_table_init): Update the table with the new functions.
659 * doc/make.texi (Conditional Functions): Changed the "if" section
660 to one on general conditional functions. Added documentation for
661 $(and ...) and $(or ...) functions.
662 * NEWS: Note new $(and ...) and $(or ...) functions.
664 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
666 * job.h (struct child): Add the dontcare bitfield.
667 * job.c (new_job): Cache dontcare flag.
668 * job.c (reap_children): Use cached dontcare flag instead of the
669 one in struct file. Fixes Savannah bug #15641.
671 2006-02-06 Paul D. Smith <psmith@gnu.org>
673 * vpath.c (selective_vpath_search): If the file we find has a
674 timestamp from -o or -W, use that instead of the real time.
675 * remake.c (f_mtime): If the mtime is a special token from -o or
676 -W, don't overwrite it with the real mtime.
677 Fixes Savannah bug #15341.
679 Updates from Markus Mauhart <qwe123@chello.at>:
681 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

687 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
688 * README.cvs: Updates for building from CVS.
690 2006-02-05 Paul D. Smith <psmith@gnu.org>
692 * file.c (enter_file): Keep track of the last double_colon entry,
693 to avoid walking the list every time we want to add a new one.
694 Fixes Savannah bug #15533.
695 * filedef.h (struct file): Add a new LAST pointer.
697 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
698 the comparison. For 64-bits systems the result of the subtraction
699 might not fit into an int. Use comparison instead.
700 Fixes Savannah bug #15534.
702 * doc/make.texi: Update the chapter on writing commands to reflect
703 the changes made in 3.81 for backslash/newline and SHELL handling.

721 * prepare_w32.bat: Remove this file from the distribution.
723 2006-01-21 Eli Zaretskii <eliz@gnu.org>
725 * remake.c (update_goal_chain): Set g->changed instead of
726 incrementing it, as it is only 8-bit wide, and could overflow if
727 many commands got started in update_file.
729 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
731 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
732 MAXIMUM_WAIT_OBJECTS.

738 (process_easy): Don't start new processes if all slots are used up.
740 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
741 are already more children than sub_proc.c can handle, behave as if
742 the load were too high.
743 (start_job_command): Fix a typo in error message when process_easy
746 2006-01-14 Eli Zaretskii <eliz@gnu.org>
748 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
749 the shell is not sh.exe.
751 * job.c (create_batch_file): Renamed from create_batch_filename;
752 all callers changed. Don't close the temporary file; return its
753 file descriptor instead. New arg FD allows to return the file
755 (construct_command_argv_internal): Use _fdopen instead of fopen to
758 2006-01-04 Paul D. Smith <psmith@gnu.org>
760 * readme.vms: Updates for case-insensitive VMS file systems from
761 Hartmut Becker <Hartmut.Becker@hp.com>.

770 2006-01-03 Paul D. Smith <psmith@gnu.org>
772 * remake.c (update_file_1): Mark a prerequisite changed if it
775 * read.c (eval): Be sure to strip off trailing whitespace from the
776 prerequisites list properly. Also, initialize all fields in
777 struct dep when creating a new one.
779 2005-12-28 Paul D. Smith <psmith@gnu.org>
781 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
782 disable warnings for MSC.

785 2005-12-17 Eli Zaretskii <eliz@gnu.org>
787 * doc/make.texi (Execution): Add a footnote about changes in
788 handling of backslash-newline sequences. Mention the differences
789 on MS-DOS and MS-Windows.
791 * NEWS: More details about building the MinGW port and a pointer
792 to README.W32. Fix the section name that describes the new
793 backward-incompatible processing of backslash-newline sequences.
794 The special processing of SHELL set to "cmd" is only relevant to
795 MS-Windows, not MS-DOS.
797 2005-12-17 Eli Zaretskii <eliz@gnu.org>
799 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
800 to DWORD, to avoid compiler warnings.
801 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and

818 garbage happened to be on the heap.
820 2005-12-12 Paul D. Smith <psmith@gnu.org>
822 * make.1: Fix some display errors and document all existing options.
823 Patch provided by Mike Frysinger <vapier@gentoo.org>.
825 2005-12-11 Paul D. Smith <psmith@gnu.org>
827 * implicit.c (pattern_search): If 2nd expansion is not set for
828 this implicit rule, replace the pattern with the stem directly,
829 and don't re-expand the variable list. Along with the other
830 .SECONDEXPANSION changes below, fixes bug #13781.
832 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
834 * implicit.c (pattern_search): Mark other files that this rule
835 builds as targets so that they are not treated as intermediates
836 by the pattern rule search algorithm. Fixes bug #13022.
838 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
840 * remake.c (notice_finished_file): Propagate the change of
841 modification time to all the double-colon entries only if

860 * read.c (record_files): Don't set deps flags if there are no deps.
861 * maintMakefile: We only need to build the templates when we are
862 creating a distribution, so don't do it for "all".
864 2005-10-24 Paul D. Smith <psmith@gnu.org>
866 Make secondary expansion optional: its enabled by declaring the
867 special target .SECONDEXPANSION.
869 * NEWS: Update information on second expansion capabilities.
870 * doc/make.texi (Secondary Expansion): Document the
871 .SECONDEXPANSION special target and its behavior.
872 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
873 prerequisite list was found in a static pattern rule.
874 (free_dep_chain): Declare a prototype.
875 * file.c (parse_prereqs): New function: break out some complexity
877 (expand_deps): If we aren't doing second expansion, replace % with
878 the stem for static pattern rules. Call the new function.
879 * filedef.h (parse_prereqs): Declare a prototype.
880 * implicit.c (pattern_search): Initialize the new staticpattern
882 * main.c (second_expansion): Declare a global variable to remember
883 if the special target has been seen. Initialize the new
884 staticpattern field for prerequisites.

886 * misc.c (free_dep_chain): New function: frees a struct dep list.
887 * read.c (read_all_makefiles): Initialize the staticpattern field.
888 (eval_makefile): Ditto.
889 (record_files): Check for the .SECONDEXPANSION target and set
890 second_expansion global if it's found.
891 Use the new free_dep_chain() instead of doing it by hand.
892 Set the staticpattern field for prereqs of static pattern targets.
894 2005-10-16 Paul D. Smith <psmith@gnu.org>
896 * main.c (main): Set CURDIR to be a file variable instead of a
897 default, so that values of CURDIR inherited from the environment
898 won't override the make value.
900 2005-09-26 Paul D. Smith <psmith@gnu.org>
902 * job.c (construct_command_argv_internal): If the line is empty
903 remember to free the temporary argv strings.
906 2005-09-16 Paul D. Smith <psmith@gnu.org>
908 * job.c (start_job_command): The noerror flag is a boolean (single
909 bit); set it appropriately.
910 Reported by Mark Eichin <eichin@metacarta.com>
912 2005-08-29 Paul D. Smith <psmith@gnu.org>
914 * function.c (func_error): On Windows, output from $(info ...)
915 seems to come in the wrong order. Try to force it with fflush().
917 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
919 * read.c (record_files): Move code that sets stem for static
920 pattern rules out of the if (!two_colon) condition so it is
921 also executed for two-colon rules. Fixes Savannah bug #13881.
923 2005-08-08 Paul D. Smith <psmith@gnu.org>
925 * make.h: Don't test that __STDC__ is non-0. Some compilers
926 (Windows for example) set it to 0 to denote "ISO C + extensions".
929 2005-08-07 Paul D. Smith <psmith@gnu.org>
931 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
932 conditional (slightly different version of a fix from Eli).
934 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
935 If make is running in parallel without -k and two jobs die in a
936 row, but not too close to each other, then make will quit without
937 waiting for the rest of the jobs to die.
939 * main.c (die): Don't reset err before calling reap_children() the
940 second time: we still want it to be in the error condition.
941 * job.c (reap_children): Use a static variable, rather than err,
942 to control whether or not the error message should be printed.
944 2005-08-06 Eli Zaretskii <eliz@gnu.org>
946 * w32/subproc/sub_proc.c: Include signal.h.
947 (process_pipe_io, process_file_io): Pass a pointer to a local
948 DWORD variable to GetExitCodeProcess. If the exit code is
949 CONTROL_C_EXIT, put SIGINT into pproc->signal.
951 * job.c [WINDOWS32]: Include windows.h.
952 (main_thread) [WINDOWS32]: New global variable.
953 (reap_children) [WINDOWS32]: Get the handle for the main thread
954 and store it in main_thread.
956 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
957 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
958 doing anything else. When we are done, close the main thread
959 handle and exit with status 130.
961 2005-07-30 Eli Zaretskii <eliz@gnu.org>
963 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
966 * main.c (find_and_set_default_shell): If found a DOSish shell,
967 set sh_found and the value of default_shell, and report the
968 findings in debug mode.
970 * job.c (construct_command_argv_internal): Check unixy_shell, not
971 no_default_sh_exe, to decide whether to use Unixy or DOSish
974 * README.W32: Update with info about the MinGW build.
976 * build_w32.bat: Support MinGW.
978 * w32/subproc/build.bat: Likewise.
980 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
983 * function.c (windows32_openpipe): Fix format strings for printing
986 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
988 (start_job_command): Fix format string for printing the result of
990 (start_job_command) [WINDOWS32]: Do not define.
991 (exec_command): Fix format string for printing HANDLE args.
993 * main.c (handle_runtime_exceptions): Fix sprintf format strings
994 to avoid compiler warnings.
995 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
996 (Note: some of these fixes were submitted independently by J. Grant)
998 2005-07-30 J. Grant <jg@jguk.org>
1000 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.

1002 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1004 2005-07-15 Paul Smith <psmith@gnu.org>
1006 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1007 we don't have a POSIX shell, then revert to the old
1008 backslash-newline behavior (where they are stripped).
1011 2005-07-08 Paul D. Smith <psmith@gnu.org>
1013 * config.h.W32.template: Reorder to match the standard config.h,
1014 for easier comparisons.
1015 From J. Grant <jg@jguk.org>

1020 arithmetic to avoid a warning.
1021 * main.c (switches): Add full-fledged final initializer.
1023 2005-07-06 Paul D. Smith <psmith@gnu.org>
1025 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1026 * signame.c (strsignal): If we found _sys_siglist[] or
1027 __sys_siglist[] use those instead of sys_siglist[].
1028 From Albert Chin <china@thewrittenword.com>
1030 2005-07-04 Paul D. Smith <psmith@gnu.org>
1032 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1033 globfree(); set up to use the GNU versions.
1034 From Martin Zinser <zinser@zinser.no-ip.info>
1036 2005-07-03 Paul D. Smith <psmith@gnu.org>

1049 declaration was checked but not present.
1051 2005-06-27 Paul D. Smith <psmith@gnu.org>
1053 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1054 to unsigned long. Fixes Savannah bug #13550.
1056 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1057 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.

1063 it if ANSI_STRING is not set.
1065 2005-06-25 Paul D. Smith <psmith@gnu.org>
1067 * read.c (eval): If no filenames are passed to any of the
1068 "include" variants, don't print an error.
1069 * doc/make.texi (Include): Document this.
1070 Fixes Savannah bug #1761.
1072 * job.c (construct_command_argv_internal): Sanitize handling of
1073 backslash/newline pairs according to POSIX: that is, keep the
1074 backslash-newline in the command script, but remove a following
1075 TAB character, if present. In the fast path, make sure that the
1076 behavior matches what the shell would do both inside and outside
1077 of quotes. In the slow path, quote the backslash and put a
1078 literal newline in the string.
1079 Fixes Savannah bug #1332.
1080 * doc/make.texi (Execution): Document the new behavior and give
1082 * NEWS: Make a note of the new behavior.
1084 * make.h [WINDOWS32]: #include <direct.h>.

1088 option was given and the file is a symlink, take the best mtime of
1089 the symlink we can get as the mtime of the file and don't fail.
1090 Fixes Savannah bug #13280.
1092 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1093 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1094 inside a variable reference. Make this function static as it's
1096 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1097 parsing an unexpanded line looking for semicolons.
1098 Fixes Savannah bug #1454.
1099 * misc.c (remove_comments): Move this to read.c and make it static
1100 as it's only used there. Call find_char_unquote() with new arg.
1101 * make.h: Remove prototypes for find_char_unquote() and
1102 remove_comments() since they're static now.
1104 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1105 its export flag and obtain its value. When we need to re-exec,
1106 increment the value and add it into the environment.
1107 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1108 * NEWS: Mention MAKE_RESTARTS.
1109 * main.c (always_make_set): New variable. Change the -B option to
1110 set this one instead.
1111 (main): When checking makefiles, only set always_make_flag if
1112 always_make_set is set AND the restarts flag is 0. When building
1113 normal targets, set it IFF always_make_set is set.
1114 (main): Avoid infinite recursion with -W, too: only set what-if
1115 files to NEW before we check makefiles if we've never restarted
1116 before. If we have restarted, set what-if files to NEW _after_ we
1118 Fixes Savannah bug #7566:
1120 2005-06-17 Paul D. Smith <psmith@gnu.org>
1122 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1123 in the prerequisites list.
1125 2005-06-12 Paul D. Smith <psmith@gnu.org>
1127 Fix Savannah bug # 1328.
1129 * configure.in: Check for atexit().
1130 * misc.c (close_stdout): Test stdout to see if writes to it have
1131 failed. If so, be sure to exit with a non-0 error code. Based on
1132 code found in gnulib.
1133 * make.h: Prototype.
1134 * main.c (main): Install close_stdout() with atexit().
1136 2005-06-10 Paul D. Smith <psmith@gnu.org>
1138 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1140 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1141 headers; make vmsWaitForChildren() static; extern vmsify().
1142 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1143 Don't create child_execute_job() here (it's in vmsjobs.c).
1144 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1146 2005-06-09 Paul D. Smith <psmith@gnu.org>
1148 * variable.c (push_new_variable_scope): File variables point
1149 directly to the global_setlist variable. So, inserting a new
1150 scope in front of that has no effect on those variables: they
1151 don't go through current_variable_set_list. If we're pushing a
1152 scope and the current scope is global, push it "the other way" so
1153 that the new setlist is in the global_setlist variable, and
1154 next points to a new setlist with the global variable set.
1155 (pop_variable_scope): Properly undo a push with the new
1157 Fixes Savannah bug #11913.
1159 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1161 * job.c (reap_children): Don't die of the command failed but
1162 the dontcare flag is set. Fixes Savannah bug #13216.
1164 * implicit.c (pattern_search): When creating a target from
1165 an implicit rule match, lookup pattern target and set precious
1166 flag in a newly created target. Fixes Savannah bug #13218.
1168 2005-05-13 Paul D. Smith <psmith@gnu.org>
1170 Implement "if... else if... endif" syntax.
1172 * read.c (eval): Push all checks for conditional words ("ifeq",
1173 "else", etc.) down into the conditional_line() function.
1174 (conditional_line): Rework to allow "else if..." clause. New
1175 return value -2 for lines which are not conditionals. The
1176 ignoring flag can now also be 2, which means "already parsed a
1177 true branch". If that value is seen no other branch of this
1178 conditional can be considered true. In the else parsing if there
1179 is extra text after the else, invoke conditional_line()
1180 recursively to see if it's another conditional. If not, it's an
1181 error. If so, raise the conditional value to this level instead
1182 of creating a new conditional nesting level. Special check for
1183 "else" and "endif", which aren't allowed on the "else" line.
1184 * doc/make.texi (Conditional Syntax): Document the new syntax.
1186 2005-05-09 Paul D. Smith <psmith@gnu.org>
1188 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1189 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1190 recurses to the w32 directory, even on non-Windows systems. Use
1191 the method suggested in the automake manual.
1192 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1193 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1195 2005-05-07 Paul D. Smith <psmith@gnu.org>
1197 * main.c (die): If we're dying with a fatal error (not that a
1198 command has failed), write back any leftover tokens before we go.
1200 * job.c (set_child_handler_action_flags): If there are jobs
1201 waiting for the load to go down, set an alarm to go off in 1
1202 second. This allows us to wake up from a potentially long-lasting
1203 read() and start a new job if the load has gone down. Turn it off
1205 (job_noop): Dummy signal handler function.
1206 (new_job): Invoke it with the new semantics.
1208 * docs/make.texi: Document secondary expansion. Various cleanups
1211 2005-05-03 Paul D. Smith <psmith@gnu.org>
1213 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1214 the targets which are to ultimately be made are called "goals";
1215 see the GNU make manual. Also, MAKECMDGOALS, etc.
1217 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1218 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1219 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1221 2005-05-02 Paul D. Smith <psmith@gnu.org>
1223 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1224 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1225 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1226 functions to vmsjobs.c. #include it into jobs.c.
1228 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1229 jobserver tokens. I found that this happens when an exported
1230 recursive variable contains a $(shell ...) function reference: in
1231 this situation we could "forget" to write back a token.
1233 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1234 we have. It's not reliable to depend on the number of children in
1235 our linked list so keep a separate count.
1236 (new_job): Check jobserver_tokens rather than children &&
1237 waiting_jobs. Increment jobserver_tokens when we get one.
1238 (free_child): If jobserver_tokens is 0, internal error. If it's
1239 >1, write a token back to the jobserver pipe (we don't write a
1240 token for the "free" job). Decrement jobserver_tokens.
1242 * main.c: Add variable master_job_slots.
1243 (main): Set it to hold the number of jobs requested if we're the
1244 master process, when using the jobserver.
1245 (die): Sanity checks: first test jobserver_tokens to make sure
1246 this process isn't holding any tokens we didn't write back.
1247 Second, if master_job_slots is set count the tokens left in the
1248 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1250 2005-04-24 Paul D. Smith <psmith@gnu.org>
1252 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1253 with -l# can lose jobserver tokens, because waiting jobs are not
1254 consulted properly when checking for the "free" token.
1256 * job.c (free_child): Count waiting_jobs as having tokens.
1257 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1258 handle jobs waiting for the load to drop.
1260 2005-04-23 Paul D. Smith <psmith@gnu.org>
1262 * main.c (main): Be careful to not core if a variable setting in
1263 the environment doesn't contain an '='. This is illegal but can
1264 happen in broken setups.
1265 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1267 2005-04-12 Paul D. Smith <psmith@gnu.org>
1269 The second expansion feature causes significant slowdown. Timing
1270 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1271 read the makefile before the feature, to 11+s to do the same
1272 operations after the feature. Additionally, memory usage
1273 increased drastically. To fix this I added some intelligence that
1274 avoids the overhead of the second expansion unless it's required.
1276 * dep.h: Add a new boolean field, need_2nd_expansion.
1278 * read.c (eval): When creating the struct dep for the target,
1279 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1280 (record_files): If there's a "%" in a static pattern rule, it gets
1281 converted to "$*" so set need_2nd_expansion to 1.
1283 * file.c (expand_deps): Rework to be more efficient. Only perform
1284 initialize_file_variables(), set_file_variables(), and
1285 variable_expand_for_file() if the need_2nd_expansion is set.
1287 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1288 (pattern_search): Ditto.
1289 * main.c (handle_non_switch_argument): Ditto.
1291 * read.c (read_all_makefiles): Ditto.
1292 (eval_makefile): Ditto.
1294 2005-04-07 Paul D. Smith <psmith@gnu.org>
1296 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1297 * variable.c (sync_Path_environment): Ditto.
1298 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1300 * main.c (main): Define the .FEATURES variable.
1301 * NEWS: Announce .FEATURES.
1302 * doc/make.texi (Special Variables): Document .FEATURES.
1304 * remake.c (check_dep): If a file is .PHONY, update it even if
1305 it's marked intermediate. Fixes Savannah bug #12331.
1307 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1309 * file.c (expand_deps): Factor out the second expansion and
1310 prerequisite line parsing logic from snap_deps().
1312 * file.c (snap_deps): Use expand_deps(). Expand and parse
1313 prerequisites of the .SUFFIXES special target first. Fixes
1314 Savannah bug #12320.
1316 2005-03-13 Paul D. Smith <psmith@gnu.org>
1318 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1321 2005-03-11 Paul D. Smith <psmith@gnu.org>
1323 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1324 available, not undefined (from Earnie Boyd).
1326 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1328 * implicit.c (pattern_search): Mark an intermediate target as
1329 precious if it happened to be a prerequisite of some (other)
1330 target. Fixes Savannah bug #12267.
1332 2005-03-09 Paul D. Smith <psmith@gnu.org>
1334 * read.c (eval_makefile): Add alloca(0).
1335 (eval_buffer): Ditto.
1337 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1339 * main.c (main): Use o_file instead of o_default when defining
1340 the .DEFAULT_TARGET special variable.
1341 * read.c (eval): Use define_variable_global() instead of
1342 define_variable() when setting new value for the .DEFAULT_TARGET
1343 special variable. Fixes Savannah bug #12266.
1345 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1347 * imlicit.c (pattern_search): Mark files for which an implicit
1348 rule has been found as targets. Fixes Savannah bug #12202.
1350 2005-03-04 Paul D. Smith <psmith@gnu.org>
1353 * doc/make.texi (Automatic Variables): Document $|.
1355 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1357 * read.c (record_files): Instead of substituting % with
1358 actual stem value in dependency list replace it with $*.
1359 This fixes stem triple expansion bug.
1361 * implicit.c (pattern_search): Copy stem to a separate
1362 buffer and make it a properly terminated string. Assign
1363 this buffer instead of STEM (which is not terminated) to
1364 f->stem. Instead of substituting % with actual stem value
1365 in dependency list replace it with $*. This fixes stem
1366 triple expansion bug.
1368 2005-03-01 Paul D. Smith <psmith@gnu.org>
1370 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1371 on Windows, as it takes a handle not a pid. Just exit.
1372 Fix from patch #3679, provided by Alessandro Vesely.
1374 * configure.in: Update check for sys_siglist[] from autoconf manual.
1375 * signame.c (strsignal): Update to use the new autoconf macro.
1377 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1379 * read.c (record_files): Add a check for the list of prerequisites
1380 of a static pattern rule being empty. Fixes Savannah bug #12180.
1382 2005-02-28 Paul D. Smith <psmith@gnu.org>
1384 * doc/make.texi (Text Functions): Update docs to allow the end
1385 ordinal for $(wordlist ...) to be 0.
1386 * function.c (func_wordlist): Fail if the start ordinal for
1387 $(wordlist ...) is <1. Matches documentation.
1388 Resolves Savannah support request #103195.
1390 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1391 previously we were stopping when !-q, exactly the opposite. This
1392 has been wrong since version 1.34, in 1994!
1393 (update_file): If we got an error don't break out to run more
1394 double-colon rules: just return immediately.
1395 Fixes Savannah bug #7144.
1397 2005-02-27 Paul D. Smith <psmith@gnu.org>
1399 * misc.c (end_of_token): Make argument const.
1400 * make.h: Update prototype.
1402 * function.c (abspath, func_realpath, func_abspath): Use
1403 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1404 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1405 * read.c (record_files): Ditto.
1406 * variable.c (do_variable_definition): Ditto.
1408 * function.c (func_error): Create a new function $(info ...) that
1409 simply prints the message to stdout with no extras.
1410 (function_table_init): Add new function to the table.
1411 * NEWS: Add $(info ...) reference.
1412 * doc/make.texi (Make Control Functions): Document it.
1414 New feature: if the system supports symbolic links, and the user
1415 provides the -L/--check-symlink-time flag, then use the latest
1416 mtime between the symlink(s) and the target file.
1418 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1419 readlink(). If both are available, define MAKE_SYMLINKS.
1420 * main.c: New variable: check_symlink_flag.
1421 (usage): Add a line for -L/--check-symlink-times to the help string.
1422 (switches): Add -L/--check-symlink-times command line argument.
1423 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1424 print a warning and disable it again.
1425 * make.h: Declare check_symlink_flag.
1426 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1427 if the file is a symlink then check each link in the chain and
1428 choose the NEWEST mtime we find as the mtime for the file. The
1429 newest mtime might be the file itself!
1430 * NEWS: Add information about this new feature.
1431 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1433 Avoid core dumps described in Savannah bug # 12124:
1435 * file.c: New variable snapped_deps remember whether we've run
1437 (snap_deps): Set it.
1438 * filedef.h: Extern it.
1439 * read.c (record_files): Check snapped_deps; if it's set then
1440 we're trying to eval a new target/prerequisite relationship from
1441 within a command script, which we don't support. Fatal.
1443 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1445 Implementation of the .DEFAULT_TARGET special variable.
1447 * read.c (eval): If necessary, update default_target_name when
1449 * read.c (record_files): Update default_target_file if
1450 default_target_name has changed.
1451 * main.c (default_target_name): Define.
1452 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1453 default_target_name is set use default_target_file as a root
1455 * filedef.h (default_target_name): Declare.
1456 * dep.h (free_dep_chain):
1457 * misc.c (free_dep_chain): Change to operate on struct nameseq
1458 and change name to free_ns_chain.
1459 * file.c (snap_deps): Update to use free_ns_chain.
1461 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1463 Implementation of the second expansion in explicit rules,
1464 static pattern rules and implicit rules.
1466 * read.c (eval): Refrain from chopping up rule's dependencies.
1467 Store them in a struct dep as a single dependency line. Remove
1468 the code that implements SySV-style automatic variables.
1470 * read.c (record_files): Adjust the code that handles static
1471 pattern rules to expand all percents instead of only the first
1472 one. Reverse the order in which dependencies are stored so that
1473 when the second expansion reverses them again they appear in
1474 the makefile order (with some exceptions, see comments in
1475 the code). Remove the code that implements SySV-style automatic
1478 * file.c (snap_deps): Implement the second expansion and chopping
1479 of dependency lines for explicit rules.
1481 * implicit.c (struct idep): Define an auxiliary data type to hold
1482 implicit rule's dependencies after stem substitution and
1485 * implicit.c (free_idep_chain): Implement.
1487 * implicit.c (get_next_word): Implement helper function for
1488 parsing implicit rule's dependency lines into words taking
1489 into account variable expansion requests. Used in the stem
1492 * implicit.c (pattern_search): Implement the second expansion
1493 for implicit rules. Also fixes bug #12091.
1495 * commands.h (set_file_variables): Declare.
1496 * commands.c (set_file_variables): Remove static specifier.
1498 * dep.h (free_dep_chain): Declare.
1499 * misc.c (free_dep_chain): Implement.
1501 * variable.h (variable_expand_for_file): Declare.
1502 * expand.c (variable_expand_for_file): Remove static specifier.
1504 * make.h (strip_whitespace): Declare.
1505 * function.c (strip_whitespace): Remove static specifier.
1507 2005-02-26 Paul D. Smith <psmith@gnu.org>
1509 * main.c (main): Check for ferror() when reading makefiles from stdin.
1510 Apparently some shells in Windows don't close pipes properly and
1513 2005-02-24 Jonathan Grant <jg@jguk.org>
1515 * configure.in: Add MinGW configuration options, and extra w32 code
1517 * Makefile.am: Add MinGW configuration options, and extra w32 code
1519 * main.c: Determine correct program string (after last \ without .exe).
1520 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1522 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1523 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1524 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1525 environment support.
1527 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1529 * function.c (func_shell): When initializing error_prefix, check
1530 that reading file name is not null. This fixes long-standing
1531 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1533 2005-02-09 Paul D. Smith <psmith@gnu.org>
1535 * maintMakefile: Update the CVS download URL to simplify them.
1536 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1537 downloading the .texi files from Savannah now.
1539 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1541 * main.c (handle_non_switch_argument): Only add variables to
1542 command_variables if they're not already there: duplicate settings
1543 waste space and can be confusing to read.
1545 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1546 this header is never included by non-WINDOWS32 code, and it
1547 requires <config.h> to define which isn't always included first.
1549 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1550 testing MINGW32 versions.
1552 * main.c (log_working_directory): flush stdout to be sure the WD
1553 change is printed before any stderr messages show up.
1555 2005-02-01 Paul D. Smith <psmith@gnu.org>
1557 * maintMakefile (po_repo): Update the GNU translation site URL.
1559 2004-12-01 Paul D. Smith <psmith@gnu.org>
1561 * main.c (main): Change char* env_shell to struct variable shell_var.
1562 * variable.c (target_environment): Use new shell_var.
1564 2004-11-30 Paul D. Smith <psmith@gnu.org>
1566 * configure.in: The old way we avoided creating build.sh from
1567 build.sh.in before build.sh.in exists doesn't work anymore; we
1568 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1569 the help!). This also keeps automake from complaining.
1570 * Makefile.am (README): Add a dummy target so automake won't
1571 complain that this file doesn't exist when we checkout from CVS.
1572 * maintMakefile (.dep_segment): Rewrite this rule since newer
1573 versions of automake don't provide DEP_FILES.
1575 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1577 Implementation of `realpath' and `abspath' built-in functions.
1579 * configure.in: Check for realpath.
1580 * function.c (abspath): Return an absolute file name that does
1581 not contain any `.' or `..' components, nor repeated `/'.
1582 * function.c (func_abspath): For each name call abspath.
1583 * function.c (func_realpath): For each name call realpath
1584 from libc or delegate to abspath if realpath is not available.
1585 * doc/make.texi (Functions for File Names): Document new functions.
1586 * doc/make.texi (Quick Reference): Ditto.
1588 2004-11-28 Paul D. Smith <psmith@gnu.org>
1590 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1591 arguments. Fixes bug #10252.
1593 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1595 * main.c (main): Set SHELL to v_noexport by default. Remember the
1596 original environment setting of SHELL in the env_shell variable.
1597 * main.h: Export new env_shell variable.
1598 * variable.c (target_environment): If we find a v_noexport
1599 variable for SHELL, add a SHELL variable with the env_shell value.
1600 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1601 * doc/make.texi (Variables/Recursion): Ditto.
1603 2004-11-28 Paul D. Smith <psmith@gnu.org>
1605 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1606 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1607 Patch by Alessandro Vesely.
1609 2004-11-12 Paul D. Smith <psmith@gnu.org>
1611 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1612 the command line if it's inside a string.
1613 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1615 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1617 * function.c (func_lastword): New function: return last word
1618 from the list of words.
1619 * doc/make.texi: Document $(lastword ). Fix broken links in
1620 Quick Reference section.
1622 2004-10-06 Paul D. Smith <psmith@gnu.org>
1624 Apply patch from Alessandro Vesely, provided with bug # 9748.
1625 Fix use of tmpnam() to work with Borland C.
1627 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1628 construction of a temporary filename, and call new function
1629 create_batch_filename().
1630 (create_batch_filename) [WINDOWS32]: New function to create a
1633 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1635 * read.c (record_target_var): Expand simple pattern-specific
1637 * variable.c (initialize_file_variables): Do not expand simple
1638 pattern-specific variable.
1640 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1642 * remake.c (update_file_1): When rebuilding makefiles inherit
1643 dontcare flag from a target that triggered update.
1645 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1647 * variable.c (initialize_file_variables): Mark pattern-specific
1648 variable as a per-target and copy export status.
1650 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1652 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1654 * implicit.c (pattern_search): When considering an implicit rule's
1655 prerequisite check that it is actually a target rather then
1656 just an entry in the file hashtable.
1658 2004-09-21 Paul D. Smith <psmith@gnu.org>
1660 * read.c (readstring): Fix some logic errors in backslash handling.
1661 (eval): Remove some unnecessary processing in buffer handling.
1662 (record_target_var): Assert that parse_variable_definition() succeeded.
1663 Reported by: Markus Mauhart <qwe123@chello.at>.
1665 * misc.c: Removed the sindex() function. All instances of this
1666 function were trivially replaceable by the standard strstr()
1667 function, and that function will always have better (or certainly
1668 no worse) performance than the very simple-minded algorithm
1669 sindex() used. This can matter with complex makefiles.
1670 * make.h: Remove the prototype for sindex().
1671 * function.c (subst_expand): Convert sindex() call to strstr().
1672 This means we no longer need to track the TLEN value so remove that.
1673 (func_findstring): Convert sindex() to strstr().
1674 * commands.c (chop_commands): Convert sindex() calls to strstr().
1675 Suggested by: Markus Mauhart <qwe123@chello.at>.
1677 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1678 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1679 If SHELL is set to CMD.EXE then assume it's batch-mode and
1680 non-unixy. I wrote the code differently from the patch, though,
1681 to make it safer. This also resolves bug #9174.
1683 2004-09-20 Paul D. Smith <psmith@gnu.org>
1685 * expand.c (variable_expand_string): Modify to invoke
1686 patsubst_expand() instead of subst_expand(); the latter didn't
1687 handle suffix patterns correctly.
1688 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1689 was used only from variable_expand_string() and is no longer used
1691 (func_subst): Ditto, on call to subst_expand().
1692 (patsubst_expand): Require the percent pointers to point to the
1693 character after the %, not to the % itself.
1694 * read.c (record_files): New call criteria for patsubst_expand().
1695 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1696 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1698 2004-09-19 Paul D. Smith <psmith@gnu.org>
1700 * function.c (subst_expand): Fix a check in by_word: look for a
1701 previous blank if we're beyond the beginning of the string, not
1702 the beginning of the word.
1703 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1705 2004-05-16 Paul D. Smith <psmith@gnu.org>
1707 * remake.c (update_goal_chain): Change the argument specifying
1708 whether we're rebuilding makefiles to be a global variable,
1709 REBUILDING_MAKEFILES.
1710 (complain): Extract the code that complains about no rules to make
1711 a target into a separate function.
1712 (update_file_1): If we tried to rebuild a file during the makefile
1713 rebuild phase and it was dontcare, then no message was printed.
1714 If we then try to build the same file during the normal build,
1715 print a message this time.
1716 (remake_file): Don't complain about un-remake-able files when
1717 we're rebuilding makefiles.
1719 2004-05-11 Paul D. Smith <psmith@gnu.org>
1721 * job.c (construct_command_argv_internal): OS/2 patches from
1722 Andreas Buening <andreas.buening@nexgo.de>.
1724 2004-05-10 Paul D. Smith <psmith@gnu.org>
1726 * remake.c (update_file): Don't walk the double-colon chain unless
1727 this is a double-colon rule. Fix suggested by Boris Kolpackov
1728 <boris@kolpackov.net>.
1730 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1731 * readme.vms: New section describing OpenVMS support and issues.
1732 * default.c (default_variables): Add support for IA64.
1733 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1734 without some privilege aborts make with the error
1735 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1736 pressing Ctrl+Y and the input device is no terminal. The change
1737 catches this error and just continues.
1739 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1741 2004-04-25 Paul D. Smith <psmith@gnu.org>
1743 * commands.c (set_file_variables): Set $< properly in the face of
1744 order-only prerequisites.
1745 Patch from Boris Kolpackov <boris@kolpackov.net>
1747 2004-04-21 Bob Byrnes <byrnes@curl.com>
1749 * main.c (main): Notice failures to remake makefiles.
1751 2004-03-28 Paul D. Smith <psmith@gnu.org>
1753 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1755 * job.c: No default shell for RISC OS.
1756 (load_too_high): Hard-code the return to 1.
1757 (construct_command_argv_internal): No sh_chars or sh_cmds.
1758 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1760 2004-03-20 Paul D. Smith <psmith@gnu.org>
1762 * variable.c (do_variable_definition): Don't append from the
1763 global set if a previous non-appending target-specific variable
1764 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1767 * expand.c (reference_variable): Don't give up on variables with
1768 no value that have the target-specific append flag set: they might
1769 have a value after all. Reported by Oliver Schmidt
1770 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1771 <nikulin@dx1cmd.inp.nsk.su>.
1773 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1774 refer to absolute pathnames in directories that don't exist: some
1775 portion of the makefile could create those directories before we
1776 match the pattern. Fixes bugs #775 and #108.
1778 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1780 * main.c (main): Free makefile_mtimes if we have any.
1781 * README.W32.template: Update documentation for the current status
1782 of the MS-Windows port.
1783 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1784 environment variable is sometimes already defined which causes the
1786 * main.c (debug_signal_handler): Only define this function if
1787 SIGUSR1 is available.
1789 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1791 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1792 * README.OS2.template: Documentation updates.
1793 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1794 link line for safety.
1795 * maintMakefile (build.sh.in): Remove an extraneous ")".
1796 * job.c (child_execute_job): Close saved FDs.
1797 * job.c (exec_command) [OS/2]: exec_command(): If the command
1798 can't be exec'ed and if the shell is not Unix-sh, then try again
1799 with argv = { "cmd", "/c", ... }. Normally, this code is never
1800 reached for the cmd shell unless the command really doesn't exist.
1801 (construct_command_argv_internal) [OS/2]: The code for cmd
1802 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1803 The CMD builtin commands are case insensitive so use strcasecmp().
1805 2004-03-19 Paul D. Smith <psmith@gnu.org>
1807 * read.c (do_define): Re-order line counter increment so the count
1808 is accurate (we were losing one line per define). Reported by
1809 Dave Yost <Dave@Yost.com>.
1811 2004-03-06 Paul D. Smith <psmith@gnu.org>
1813 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1815 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1816 * misc.c (message,error,fatal): Ditto.
1817 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1818 * config.h.W32.template: Ditto.
1819 * config.h-vms.template: Ditto.
1820 * config.ami.template: Ditto.
1822 2004-03-04 Paul D. Smith <psmith@gnu.org>
1824 * README.template: Add a note about broken /bin/sh on SunOS
1825 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1827 * misc.c (message, error, fatal): Don't use "..." if we're using
1828 varargs. ansi2knr should handle this but it doesn't work: it
1829 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1830 done. On many systems (SunOS for example) va_dcl is a #define.
1831 So, force the use of the non-"..." version on pre-ANSI compilers.
1833 * maintMakefile (sign-dist): Create some rules to help automate
1834 the new GNU ftp upload method.
1836 2004-02-24 Paul D. Smith <psmith@gnu.org>
1838 * config.h.W32.template: Add HAVE_STDARG_H
1839 * config.h-vms.template: Ditto.
1840 * config.ami.template: Ditto.
1842 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1844 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1845 * build_w32.bat: Remove extra "+".
1847 2004-02-23 Paul D. Smith <psmith@gnu.org>
1849 * make.h: Create an UNUSED macro to mark unused parameters.
1850 * (many): Clean up warnings by applying UNUSED, fixing
1851 signed/unsigned incompatibilities, etc.
1853 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1855 * filedef.h: Name the command_state enumeration.
1856 * file.c (set_command_state): Use the enumeration in the function
1859 * configure.in: Explicitly set SET_MAKE to empty, to disable
1860 MAKE=make even when no make already exists. Fix bug #3823.
1862 2004-02-22 Paul D. Smith <psmith@gnu.org>
1864 * maintMakefile: Perl script to clean up all non-CVS files. Use
1865 it on all the subdirectories for the cvs-clean target.
1867 * main.c (decode_switches): Require non-empty strings for all our
1868 string command-line options. Fixes Debian bug # 164165.
1870 * configure.in: Check for stdarg.h and varargs.h.
1871 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1872 for printing messages.
1873 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1878 A number of patches for OS/2 support from Andreas Buening
1879 <andreas.buening@nexgo.de>:
1881 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1882 disable the SIGCHLD handler.
1883 (reap_children) [OS/2]: Remove special handling of job_rfd.
1884 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1885 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1886 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1887 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1888 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1891 2004-02-21 Paul D. Smith <psmith@gnu.org>
1893 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1894 <mail@kristov.de> reports that if process_begin() fails we don't
1895 handle the error condition correctly in all cases.
1896 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1897 to have a newline on the message.
1899 * job.c (construct_command_argv_internal): Add "test" to UNIX
1900 sh_cmds[]. Fixes Savannah bug # 7606.
1902 2004-02-04 Paul D. Smith <psmith@gnu.org>
1904 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1905 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1906 Hartmut Becker <Hartmut.Becker@hp.com>.
1908 2004-01-21 Paul D. Smith <psmith@gnu.org>
1910 * job.c (load_too_high): Implement an algorithm to control the
1911 "thundering herd" problem when using -l to control job creation
1912 via the load average. The system only recomputes the load once a
1913 second but we can start many jobs in a second. To solve this we
1914 keep track of the number of jobs started in the last second and
1915 apply a weight to try to guess what a correct load would be.
1916 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1917 Also fixes bug #4693.
1918 (reap_children): Decrease the job count for this second.
1919 (start_job_command): Increase the job count for this second.
1921 * read.c (conditional_line): Expand the text after ifn?def before
1922 checking to see if it's a single word. Fixes bug #7257.
1924 2004-01-09 Paul D. Smith <psmith@gnu.org>
1926 * file.c (print_file): Recurse to print all targets in
1927 double-colon rules. Fixes bug #4518, reported (with patch) by
1928 Andrew Chatham <chatham@google.com>.
1930 2004-01-07 Paul D. Smith <psmith@gnu.org>
1932 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1933 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1934 AC_FUNC_SETVBUF_REVERSED.
1936 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1937 (MAKE Variable): Fix Savannah bug #4898.
1939 * job.c (construct_command_argv_internal): Add "!" to the list of
1940 shell escape chars. POSIX sh allows it to appear before a
1941 command, to negate the exit code. Fixes bug #6404.
1943 * implicit.c (pattern_search): When matching an implicit rule,
1944 remember which dependencies have the ignore_mtime flag set.
1945 Original fix provided in Savannah patch #2349, by Benoit
1946 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1948 2003-11-22 Paul D. Smith <psmith@gnu.org>
1950 * README.W32.template (Outputs): Clarification on -j with
1951 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1954 2003-11-02 Paul D. Smith <psmith@gnu.org>
1956 * function.c (func_if): Strip all the trailing whitespace from the
1957 condition, then don't expand it. Fixed bug # 5798.
1959 * expand.c (recursively_expand_for_file): If we're expanding a
1960 variable with no file context, then use the variable's context.
1963 2003-10-21 Paul D. Smith <psmith@gnu.org>
1965 * main.c (log_working_directory): Add newlines to printf()s.
1967 * README.cvs: Add a note to ignore warnings during autoreconf.
1969 * maintMakefile (po_repo): Set a new URL for PO file updates.
1970 (get-config/config.guess get-config/config.sub): Get these files
1971 from the Savannah config project instead of ftp.gnu.org.
1973 2003-10-05 Paul Eggert <eggert@twinsun.com>
1975 * main.c (main): Avoid potential subscript error if environ has
1978 2003-08-22 Paul D. Smith <psmith@gnu.org>
1980 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1981 systems which don't yet implement the C89 standard :-/.
1983 2003-07-18 Paul D. Smith <psmith@gnu.org>
1985 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1986 [WINDOWS32]: Initialize hash.
1988 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1990 * dir.c (read_dirstream): Provide a workaround for broken versions of
1991 the MinGW dirent structure.
1993 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1995 * w32/include/dirent.h: Add __MINGW32__ filter.
1997 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1999 * make.h: Add global declaration of *make_host.
2000 * main.c (print_usage): Remove local declaration of *make_host.
2001 (print_version): Display "This program built for ..." after Copyright
2004 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2006 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2007 execution of "makeinfo --html make.texi".
2009 2003-04-30 Paul D. Smith <psmith@gnu.org>
2011 * build.template: Make some changes to maybe allow this script to
2012 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2014 * README.OS2.template: New file for OS/2 support. Original
2015 contributed by Andreas Buening.
2016 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2019 2003-04-19 Paul D. Smith <psmith@gnu.org>
2021 Fix bug #1405: allow a target to match multiple pattern-specific
2024 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2025 variable.c, where they've always belonged.
2026 * rule.h: Move the prototypes and struct pattern_var as well.
2027 * variable.c (initialize_file_variables): Invoke
2028 lookup_pattern_var() in a loop, until no more matches are found.
2029 If a match is found, create a new variable set for the target's
2030 pattern variables. Then merge the contents of each matching
2031 pattern variable set into the target's pattern variable set.
2032 (lookup_pattern_var): Change this function to be usable
2033 in a loop. It takes a starting position: if NULL, start at the
2034 beginning; if non-NULL, start with the pattern variable after that
2035 position, and return the next matching pattern.
2036 (create_pattern_var): Create a unique instance of
2037 pattern-specific variables for every definition in the makefile.
2038 Don't combine the same pattern together. This allows us to
2039 process the variable handling properly even when the same pattern
2040 is used multiple times.
2041 (parse_variable_definition): New function: break out the parsing
2042 of a variable definition line from try_variable_definition.
2043 (try_variable_definition): Call parse_variable_definition to
2045 (print_variable_data_base): Print out pattern-specific variables.
2046 * variable.h (struct variable): Remember when a variable is
2047 conditional. Also remember its flavor.
2048 (struct pattern_var): Instead of keeping a variable set, we just
2049 keep a single variable for each pattern.
2050 * read.c (record_target_var): Each pattern variable contains only a
2051 single variable, not a set, so create it properly.
2052 * doc/make.texi (Pattern-specific): Document the new behavior.
2054 2003-04-17 Paul D. Smith <psmith@gnu.org>
2056 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2057 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2058 file/directory naming rules for VMS so I can't tell whether this
2061 2003-04-09 Paul D. Smith <psmith@gnu.org>
2063 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2064 DOS-style pathnames: backslash separators and drive specifiers.
2066 2003-03-28 Paul D. Smith <psmith@gnu.org>
2068 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2069 the intermediate flag on all targets. Fixes bug #2515.
2071 2003-03-24 Paul D. Smith <psmith@gnu.org>
2073 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2074 Upgrade to autoconf 2.57 and automake 1.7.3.
2076 * job.c: More OS/2 changes from Andreas Buening.
2078 * file.c (print_file): Fix variable initialization.
2081 * remake.c (notice_finished_file):
2083 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2084 some calls (like readdir()) return NULL in valid situations
2085 without resetting errno. Fixes bug #2846.
2087 2003-02-25 Paul D. Smith <psmith@gnu.org>
2089 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2091 * job.c (_is_unixy_shell) [OS/2]: New function.
2092 Set default shell to /bin/sh.
2093 (reap_children): Close the job_rfd pipe here since we don't use a
2095 (set_child_handler_action_flags): define this to empty on OS/2.
2096 (start_job_command): Close the jobserver pipe and use
2097 child_execute_job() instead of fork/exec.
2098 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2099 rather than exec'ing, then reconfigure stdin/stdout.
2100 (exec_command): Rewrite to use spawn instead of exec. Return the
2103 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2104 in DOS. Handle the TEMP environment variable as in DOS. Don't
2105 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2106 use -j in DOS mode. Use child_execute_job() instead of
2109 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2112 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2113 prototypes that return values.
2115 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2117 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2118 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2120 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2123 2003-02-24 Paul D. Smith <psmith@gnu.org>
2125 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2126 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2127 (child_execute_job) [VMS]: Handle error status properly.
2128 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2130 * function.c (func_shell): Use EINTRLOOP() while reading from the
2131 subshell pipe (Fixes bug #2502).
2132 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2134 * main.c (main): Ditto.
2136 2003-01-30 Paul D. Smith <psmith@gnu.org>
2138 * read.c (eval): eval() was not fully reentrant, because the
2139 collapsed buffer was static. Change it to be an automatic
2140 variable so that eval() can be invoked recursively.
2142 (eval): Apply patch # 1022: fix memory reference error on long
2143 target-specific variable lines.
2144 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2146 * function.c (check_numeric): Combine the is_numeric() function
2147 into this function, since it's only called from one place.
2148 Constify this function. Have it print the incorrect string in the
2149 error message. Fixes bug #2407.
2150 (strip_whitespace): Constify.
2151 (func_if): Constify.
2152 * expand.c (expand_argument): Constify.
2154 2003-01-29 Paul D. Smith <psmith@gnu.org>
2156 Fix bug # 2169, also reported by other people on various systems.
2158 * make.h: Some systems, such as Solaris and PTX, do not fully
2159 implement POSIX-compliant SA_RESTART functionality; important
2160 system calls like stat() and readdir() can still fail with EINTR
2161 even if SA_RESTART has been set on the signal handler. So,
2162 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2163 EINTR for system calls which return -1 or 0 (NULL), respectively,
2165 Also, remove the old atomic_stat()/atomic_readdir() and
2166 HAVE_BROKEN_RESTART handling.
2168 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2170 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2171 * remake.c (touch_file): Ditto.
2173 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2174 * read.c (construct_include_path): Ditto.
2175 * remake.c (name_mtime): Ditto.
2176 * vpath.c (selective_vpath_search): Ditto.
2177 * dir.c (find_directory): Ditto.
2178 (local_stat): Ditto.
2179 (find_directory): Use ENULLLOOP() to wrap opendir().
2180 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2182 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2183 atomic_readdir() handling.
2185 2003-01-22 Paul D. Smith <psmith@gnu.org>
2187 * function.c (func_call): Fix Bug #1744. If we're inside a
2188 recursive invocation of $(call ...), mask any of the outer
2189 invocation's arguments that aren't used by this one, so that this
2190 invocation doesn't "inherit" them accidentally.
2192 2002-12-05 Paul D. Smith <psmith@gnu.org>
2194 * function.c (subst_expand): Valery Khamenia reported a
2195 pathological performance hit when doing substitutions on very
2196 large values with lots of words: turns out we were invoking
2197 strlen() a ridiculous number of times. Instead of having each
2198 call to sindex() call strlen() again, keep track of how much of
2199 the text we've seen and pass the length to sindex().
2201 2002-11-19 Paul D. Smith <psmith@gnu.org>
2203 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2206 2002-11-16 Paul D. Smith <psmith@gnu.org>
2208 * NMakefile.template (OBJS): Add hash.c object file.
2209 * SMakefile.template (srcs): Ditto.
2210 * Makefile.ami (objs): Ditto.
2211 * build_w32.bat: Ditto.
2213 * Makefile.DOS.template: Remove extra dependencies.
2215 2002-10-25 Paul D. Smith <psmith@gnu.org>
2217 * expand.c (install_variable_buffer): New function. Install a new
2218 variable_buffer context and return the previous one.
2219 (restore_variable_buffer): New function. Free the current
2220 variable_buffer context and put a previously saved one back.
2221 * variable.h: Prototypes for {install,restore}_variable_buffer.
2222 * function.c (func_eval): Push a new variable_buffer context
2223 before we eval, then restore the old one when we're done.
2226 * read.c (install_conditionals): New function. Install a new
2227 conditional context and return the previous one.
2228 (restore_conditionals): New function. Free the current
2229 conditional context and put a previously saved one back.
2230 (eval): Use the {install,restore}_conditionals for "include"
2232 (eval_buffer): Use {install,restore}_conditionals to preserve the
2233 present conditional state before we evaluate the buffer.
2236 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2238 (Recursion): Add a variable index entry for CURDIR.
2240 * README.cvs: Update to appropriate versions.
2241 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2242 don't need to copy loadavg.c: automake is smart enough to create
2243 it for me. Still have a bug in automake related to ansi2knr tho.
2245 2002-10-14 Paul D. Smith <psmith@gnu.org>
2247 * remake.c (notice_finished_file): Only touch targets if they have
2248 at least one command (as per POSIX). Resolve Bug #1418.
2250 * *.c: Convert to using ANSI C-style function definitions.
2251 * Makefile.am: Enable the ansi2knr feature of automake.
2252 * configure.in: ditto.
2254 2002-10-13 Paul D. Smith <psmith@gnu.org>
2256 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2257 for automatic variable values like $^, etc. In the case of very
2258 large lists of prerequisites this causes problems. Instead reuse
2259 a static buffer (resizeable) for each variable.
2261 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2262 target-specific variable definitions. Check for it and set an
2264 (record_target_var): Set the export field to v_export if the
2265 "exported" flag is set.
2266 * doc/make.texi (Target-specific): Document the ability to use
2269 * doc/make.texi: Change the name of the section on automatic
2270 variables from "Automatic" to "Automatic Variables". Added text
2271 clarifying the scope of automatic variables.
2273 2002-10-04 Paul D. Smith <psmith@gnu.org>
2275 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2277 (record_files): Ditto.
2279 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2280 the search for the '=' to only within the enclosing parens.
2282 2002-10-03 Paul D. Smith <psmith@gnu.org>
2284 Version 3.80 released.
2286 * dir.c: Change hash functions to use K&R function definition style.
2287 * function.c: Ditto.
2289 * variable.c: Ditto.
2291 Update to automake 1.7.
2293 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2294 (pdf): Remove this target as automake now provides one.
2296 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2298 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2300 * makefile.com: Updates for GNU make 3.80.
2301 * makefile.vms: Ditto.
2303 2002-09-23 Paul D. Smith <psmith@gnu.org>
2305 * read.c (enum make_word_type): Remove w_comment.
2306 (get_next_mword): Don't treat comment characters as special; where
2307 this function is used we will never see a comment (it's stripped
2308 before we get here) and treating comments specially means that
2309 targets like "foo\#bar" aren't handled properly.
2311 2002-09-18 Paul D. Smith <psmith@gnu.org>
2313 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2315 * read.c (eval): Expansion of arguments to export/unexport was
2316 ignoring all arguments after the first one. Change the algorithm
2317 to expand the whole line once, then parse the results.
2319 2002-09-17 Paul D. Smith <psmith@gnu.org>
2321 Fix Bug #940 (plus another bug I found while looking at this):
2323 * read.c (record_target_var): enter_file() will add a new entry if
2324 it's a double-colon target: we don't want to do that in this
2325 situation. Invoke lookup_file() and only enter_file() if it does
2326 not already exist. If the file we get back is a double-colon then
2327 add this variable to the "root" double-colon target.
2329 * variable.c (initialize_file_variables): If this file is a
2330 double-colon target but is not the "root" target, then initialize
2331 the root and make the root's variable list the parent of our
2334 2002-09-13 Paul D. Smith <psmith@gnu.org>
2336 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2338 * hash.c (round_up_2): Get rid of a warning.
2340 2002-09-12 Paul D. Smith <psmith@gnu.org>
2342 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2343 so it doesn't complain about getloadavg.c.
2345 * commands.c (set_file_variables): Make sure we always alloca() at
2346 least 1 character for the value of $? (for '\0').
2348 2002-09-11 Paul D. Smith <psmith@gnu.org>
2350 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2351 macro to use RESULT instead of the incorrect _RESULT_.
2353 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2354 and atomic_readdir(). We need to #include dirent.h to get this to
2356 * misc.c (atomic_readdir): Fix typos.
2358 2002-09-10 Paul D. Smith <psmith@gnu.org>
2360 * read.c (eval): Expand variable lists given to export and
2361 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2362 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2364 * doc/make.texi (Variables/Recursion): Document this.
2365 (Conditional Syntax): And here.
2367 2002-09-09 Paul D. Smith <psmith@gnu.org>
2369 * configure.in: Check for memmove().
2371 2002-09-07 Paul D. Smith <psmith@gnu.org>
2373 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2374 Michael Sterrett <msterret@coat.com> reports that while it has
2375 SA_RESTART, it does not work properly.
2377 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2378 that invokes stat() and loops to do it again if it returns EINTR.
2379 (atomic_readdir): Ditto, with readdir().
2381 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2382 and readdir() to atomic_stat() and atomic_readdir().
2384 2002-09-04 Paul D. Smith <psmith@gnu.org>
2386 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2387 reports that GNU make sometimes doesn't recognize that targets can
2388 be made, when directories can be created as prerequisites. He
2389 reports that changing the order of predicates in the DEP->changed
2390 flag test so that lookup_file() is always performed, solves this
2393 2002-08-08 Paul D. Smith <psmith@gnu.org>
2395 * configure.in: Require a newer version of gettext.
2397 * misc.c (perror_with_name): Translate the format string (for
2398 right-to-left language support).
2399 (pfatal_with_name): Ditto.
2401 * main.c: Create a static array of strings to store the usage
2402 text. This is done to facilitate translations.
2403 (struct command_switch): Remove argdesc and description fields.
2404 (switches): Remove values for obsolete fields.
2405 (print_usage): Print each element of the usage array.
2407 * hash.c: Change function definitions to be K&R style.
2409 2002-08-02 Paul D. Smith <psmith@gnu.org>
2411 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2412 this one because it's too hard to get right. We'll look at it for
2414 * main.c (main): Don't create the .TARGETS variable.
2415 * variable.c (handle_special_var): Don't handle .TARGETS.
2417 2002-08-01 Paul D. Smith <psmith@gnu.org>
2419 * main.c (switches): Add a new option, -B (--always-make). If
2420 specified, make will rebuild all targets that it encounters even
2421 if they don't appear to be out of date.
2422 (always_make_flag): New flag.
2423 * make.h: Extern always_make_flag.
2424 * remake.c (update_file_1): Check always_make_flag; if it's set we
2425 will always rebuild any target we can, even if none of its
2426 prerequisites are newer.
2429 * doc/make.texi (Shell Function): Make it clear that make
2430 variables marked as "export" are not passed to instances of the
2433 Add new introspection variable .VARIABLES and .TARGETS.
2435 * variable.c (handle_special_var): New function. If the variable
2436 reference passed in is "special" (.VARIABLES or .TARGETS),
2437 calculate the new value if necessary. .VARIABLES is handled here:
2438 walk through the hash of defined variables and construct a value
2439 which is a list of the names. .TARGETS is handled by
2440 build_target_list().
2441 (lookup_variable): Invoke handle_special_var().
2442 * file.c (build_target_list): Walk through the hask of known files
2443 and construct a list of the names of all the ones marked as
2445 * main.c (main): Initialize them to empty (and as simple variables).
2446 * doc/make.texi (Special Variables): Document them.
2447 * NEWS: Mention them.
2449 * variable.h (struct variable): Add a new flag "exportable" which
2450 is true if the variable name is valid for export.
2451 * variable.c (define_variable_in_set): Set "exportable" when a new
2452 variable is defined.
2453 (target_environment): Use the "exportable" flag instead of
2454 re-checking the name here... an efficiency improvement.
2456 2002-07-31 Paul D. Smith <psmith@gnu.org>
2458 * config.h-vms.template: Updates to build on VMS. Thanks to
2459 Brian_Benning@aksteel.com for helping verify the build.
2460 * makefile.com: Build the new hash.c file.
2461 * hash.h: Use strcpmi(), not stricmp(), in the
2462 HAVE_CASE_INSENSITIVE_FS case.
2464 2002-07-30 Paul D. Smith <psmith@gnu.org>
2466 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2467 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2468 Reported by <Brian_Benning@aksteel.com>.
2470 2002-07-10 Paul D. Smith <psmith@gnu.org>
2472 * variable.c (pop_variable_scope): Remove variable made unused by
2473 new hash infrastructure.
2474 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2475 comparisons as well as name comparisons.
2476 * variable.h: Add a prototype for new hash_init_function_table().
2477 * file.c (lookup_file): Remove variables made unused by new hash
2479 * dir.c (directory_contents_hash_2): Missing return of hash value.
2480 (dir_contents_file_exists_p): Remove variables made unused by new
2481 hash infrastructure.
2484 Installed Greg McGary's integration of the hash functions from the
2485 GNU id-utils package:
2487 2002-07-10 Greg McGary <greg@mcgary.org>
2489 * scripts/functions/filter-out: Add literals to to the
2490 pattern space in order to add complexity, and trigger
2491 use of an internal hash table. Fix documentation strings.
2492 * scripts/targets/INTERMEDIATE: Reverse order of files
2493 passed to expected `rm' command.
2495 2002-07-10 Greg McGary <greg@mcgary.org>

2587 2002-07-10 Paul D. Smith <psmith@gnu.org>
2589 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2590 prerequisite list. A real SysV make will expand the entire
2591 prerequisites list _twice_: we don't do that as it's a big
2592 backward-compatibility problem. We only replace those specific
2595 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2596 references left in the list of prerequisites. Check for .POSIX as
2597 we record targets, so we can disable non-POSIX behavior while
2598 reading makefiles as well as running them.
2599 (eval): Check the prerequisite list to see if we have anything
2600 that looks like a SysV prerequisite variable reference.
2602 2002-07-09 Paul D. Smith <psmith@gnu.org>
2604 * doc/make.texi (Prerequisite Types): Add a new section describing
2605 order-only prerequisites.
2607 * read.c (uniquize_deps): If we have the same file as both a
2608 normal and order-only prereq, get rid of the order-only prereq,
2609 since the normal one supersedes it.
2611 2002-07-08 Paul D. Smith <psmith@gnu.org>
2613 * AUTHORS: Added Greg McGary to the AUTHORS file.
2614 * NEWS: Blurbed order-only prerequisites.
2615 * file.c (print_file): Show order-only deps properly when printing
2618 * maintMakefile: Add "update" targets for wget'ing the latest
2619 versions of various external files. Taken from Makefile.maint in
2622 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2623 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2625 2002-07-07 Paul D. Smith <psmith@gnu.org>
2627 * po/*.po: Remove. We'll use wget to retrieve them at release
2630 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2631 rather than a shell you get an exception. Make sure we look up
2632 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2634 * remake.c (notice_finished_file): Fix handling of -t flag.
2635 Patch provided by Henning Makholm <henning@makholm.net>.
2637 * implicit.c (pattern_search): Some systems apparently run short
2638 of stack space, and using alloca() in this function caused an
2639 overrun. I modified it to use xmalloc() on the two variables
2640 which seemed like they might get large. Fixes Bug #476.
2642 * main.c (print_version): Update copyright notice to conform with
2644 (print_usage): Update help output.
2646 * function.c (func_eval): Create a new make function, $(eval
2647 ...). Expand the arguments, put them into a buffer, then invoke
2648 eval_buffer() on the resulting string.
2649 (func_quote): Create a new function, $(quote VARNAME). Inserts
2650 the value of the variable VARNAME without expanding it any
2653 * read.c (struct ebuffer): Change the linebuffer structure to an
2654 "eval buffer", which can be either a file or a buffer.
2655 (eval_makefile): Move the code in the old read_makefile() which
2656 located a makefile into here: create a struct ebuffer with that
2657 information. Have it invoke the new function eval() with that
2659 (eval_buffer): Create a new function that creates a struct ebuffer
2660 that holds a string buffer instead of a file. Have it invoke
2661 eval() with that ebuffer.
2662 (eval): New function that contains the guts of the old
2663 read_makefile() function: this function parses makefiles. Obtains
2664 data to parse from the provided ebuffer. Some modifications to
2665 make the flow of the function cleaner and clearer. Still could
2666 use some work here...
2667 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2668 contents of the define/endef variable from the ebuffer.
2669 (readstring): Read the next line from a string-style ebuffer.
2670 (readline): Read the next line from an ebuffer. If it's a string
2671 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2674 * dep.h (eval_buffer): Prototype eval_buffer();
2676 * variable.c (do_variable_definition): Make sure that all
2677 non-target-specific variables are registered in the global set.
2678 If we're invoked from an $(eval ...) we might be inside a $(call
2679 ...) or other function which has pushed a variable scope; we still
2680 want to define our variables from evaluated makefile code in the
2683 2002-07-03 Greg McGary <greg@mcgary.org>
2685 * dep.h (struct dep) [ignore_mtime]: New member.
2686 [changed]: convert to a bitfield.
2687 * implicit.c (pattern_search): Zero ignore_mtime.
2688 * main.c (main, handle_non_switch_argument): Likewise.
2689 * rule.c (convert_suffix_rule): Likewise.
2690 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2691 (read_makefile): Parse '|' in prerequisite list.
2692 (uniquize_deps): Consider ignore_mtime when comparing deps.
2693 * remake.c (update_file_1, check_dep): Don't force remake for
2694 dependencies that have d->ignore_mtime.
2695 * commands.c (FILE_LIST_SEPARATOR): New constant.
2696 (set_file_variables): Don't include a
2697 prerequisite in $+, $^ or $? if d->ignore_mtime.
2700 2002-06-18 Paul D. Smith <psmith@gnu.org>
2702 * make.texinfo: Updates for next revision. New date/rev/etc.
2703 Recreate all Info menus. Change license on the manual to the GNU
2704 Free Documentation License. A number of typos.
2705 (Variables Simplify): Don't use "-" before it's defined.
2706 (Automatic Prerequisites): Rewrite the target example to work
2707 properly if the compile fails. Remove incorrect comments about
2708 how "set -e" behaves.
2709 (Text Functions): Move the "word", "wordlist", "words", and
2710 "firstword" functions here, from "File Name Functions".
2711 * make-stds.texi: Update from latest GNU version.
2712 * fdl.texi: (created) Import the latest GNU version.
2714 2002-06-06 Paul D. Smith <psmith@gnu.org>
2716 * variable.c (do_variable_definition): New function: extract the
2717 part of try_variable_definition() that actually sets the value
2718 into a separate function.
2719 (try_variable_definition): Call do_variable_definition() after
2720 parsing the variable definition string.
2721 (define_variable_in_set): Make the name argument const.
2723 * variable.h (enum variable_flavor): Make public.
2724 (do_variable_definition): Create prototype.
2726 * read.c (read_all_makefiles): Create a new built-in variable,
2728 (read_makefile): Add each makefile read in to this variable value.
2730 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2732 * Makefile.DOS.template: Tweak according to changes in the
2733 distribution. Add back the dependencies of *.o files.
2735 * configh.dos.template: Synchronize with config.h.in.
2737 2002-05-09 Paul D. Smith <psmith@gnu.org>
2739 * file.c (file_timestamp_now): Use K&R function declaration.
2741 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2742 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2743 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2744 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2745 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2746 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2747 nlist.n_name is a pointer rather than an array.
2749 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2750 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2751 * configure.in: Use it instead of the old version.
2753 * main.c (main): Prefer setvbuf() to setlinebuf().
2755 2002-05-08 Paul D. Smith <psmith@gnu.org>
2757 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2758 (loadavg_LDADD): Ditto.
2760 2002-04-29 Paul D. Smith <psmith@gnu.org>
2762 * expand.c (recursively_expand_for_file): Rename
2763 recursively_expand() to recursively_expand_for_file() and provide
2764 an extra argument, struct file. If the argument is provided, set
2765 the variable scope to that of the file before expanding.
2766 * variable.h (recursively_expand): Make this a macro that invokes
2767 recursively_expand_for_file() with a NULL file pointer.
2768 * variable.c (target_environment): Call the renamed function and
2769 provide the current file context.
2770 Fixes Debian bug #144306.
2772 2002-04-28 Paul D. Smith <psmith@gnu.org>
2774 Allow $(call ...) user-defined variables to be self-referencing
2775 without throwing an error. Allows implementation of transitive
2776 closures, among other possibly useful things.
2777 Requested by: Philip Guenther <guenther@sendmail.com>
2779 * variable.h (struct variable): Add a new field: exp_count, and
2780 new macros to hold its size and maximum value.
2781 (warn_undefined): Make this a macro.
2782 * variable.c (define_variable_in_set): Initialize it.
2783 * expand.c (recursively_expand): If we detect recursive expansion
2784 of a variable, check the exp_count field. If it's greater than 0
2785 allow the recursion and decrement the count.
2786 (warn_undefined): Remove this (now a macro in variable.h).
2787 * function.c (func_call): Before we expand the user-defined
2788 function, modify its exp_count field to contain the maximum
2789 number of recursive calls we'll allow. After the call, reset it
2792 2002-04-21 Paul D. Smith <psmith@gnu.org>
2794 Modified to use latest autoconf (2.53), automake (1.6.1), and
2795 gettext (0.11.1). We're using gettext's new "external" support,
2796 to avoid including libintl source with GNU make.
2798 * README.cvs: New file. Explain how to build GNU make from CVS.
2800 * configure.in: Modify checking for the system glob library.
2801 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2802 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2803 etc. will manage it correctly). Set an automake conditional
2804 USE_LOCAL_GLOB to decide whether to compile the glob library.
2806 * getloadavg.c (main): Include make.h in the "TEST" program to
2809 * Makefile.am: Remove special rules for loadavg. Replace them
2810 with Automake capabilities for building extra programs.
2812 * signame.c: This file does nothing if the system provide
2813 strsignal(). If not, it implements strsignal(). If the system
2814 doesn't define sys_siglist, then we make our own; otherwise we use
2816 * signame.h: Removed.
2818 * main.c (main): No need to invoke signame_init(). Update copyright.
2820 * ABOUT-NLS: Removed.
2821 * gettext.c: Removed.
2822 * gettext.h: Get a simplified copy from the gettext package.
2824 * i18n/*.po: Moved to po/.
2827 * config/*: Created. Contains package configuration helper files.
2828 * config.guess, config.sub: Moved to config directory.
2830 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2831 Rework to use new-style autoconf features. Use the "external"
2832 mode for gettext. Make the build.sh config file conditional on
2833 whether build.sh.in exists, to avoid autoconf errors.
2834 * acinclude.m4: Removed almost all macros as being obsolete.
2835 Rewrote remaining macros to use AC_DEFINE.
2836 * acconfig.h: Removed.
2838 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2839 conditional to handle customs support. Remove special handling
2842 2002-04-20 Paul D. Smith <psmith@gnu.org>
2844 * function.c (func_call): Don't mark the argument variables $1,
2845 etc. as recursive. They've already been fully expanded so
2846 there's no need to do it again, and doing so strips escaped $'s.
2847 Reported by Sebastian Glita <glseba@yahoo.com>.
2849 * remake.c (notice_finished_file): Walk through double-colon
2850 entries via the prev field, not the next field!
2851 Reported by Greg McGary <greg@mcgary.org>.
2853 * main.c (main): If the user specifies -q and asks for a specific
2854 target which is a makefile, we got an assert. In that case it
2855 turns out we should continue normally instead.
2857 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2859 * i18n/he.po: Installed a new translation.
2861 2002-01-07 Paul D. Smith <psmith@gnu.org>
2863 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2865 2001-12-04 Paul D. Smith <psmith@gnu.org>
2867 * i18n/ja.po: Installed an updated translation.
2869 2001-09-06 Paul Eggert <eggert@twinsun.com>
2871 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2872 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2874 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2876 (main): Get rid of any avoidable limit on stack size.
2878 2001-09-04 Paul D. Smith <psmith@gnu.org>
2880 * i18n/da.po: Installed an updated translation.
2882 2001-08-03 Paul D. Smith <psmith@gnu.org>
2884 * i18n/fr.po: Installed an updated translation.
2885 Resolves Debian bug #106720.
2887 2001-06-13 Paul D. Smith <psmith@gnu.org>
2889 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2892 2001-06-11 Paul D. Smith <psmith@gnu.org>
2894 * i18n/ko.po: Installed a new translation.
2896 2001-05-06 Paul D. Smith <psmith@gnu.org>
2898 Modify the EINTR handling.
2900 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2901 the way in which we manage the file descriptor/signal handler race
2902 trap to be more efficient.
2904 2001-05-06 Paul Eggert <eggert@twinsun.com>
2906 Restart almost all system calls that are interrupted, instead
2907 of worrying about EINTR. The lone exception is the read() for
2910 * configure.in (HAVE_SA_RESTART): New macro.
2911 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2912 * main.c (main): Use SA_RESTART instead of the old,
2913 nonstandard SA_INTERRUPT.
2915 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2916 * main.c (bsd_signal): New function or macro,
2917 if the implementation doesn't supply it.
2918 (The bsd_signal function will be in POSIX 1003.1-200x.)
2919 (HANDLESIG): Remove.
2920 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2922 * make.h (EINTR_SET): Remove.
2923 (SA_RESTART): New macro.
2925 * arscan.c (ar_member_touch): Don't worry about EINTR.
2926 * function.c (func_shell): Likewise.
2927 * job.c (reap_children, free_child, new_job): Likewise.
2928 * main.c (main): Likewise.
2929 * remake.c (touch_file, name_mtime): Likewise.
2931 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2932 if fstat failed with errno!=EINTR, the error was ignored.
2934 * job.c (set_child_handler_action_flags): New function.
2935 (new_job): Use it to temporarily clear the SIGCHLD action flags
2936 while reading the token.
2938 2001-05-02 Paul D. Smith <psmith@gnu.org>
2940 * job.c (start_job_command): Don't add define/endef per-line flags
2941 to the top-level flags setting.
2943 2001-04-03 Paul D. Smith <psmith@gnu.org>
2945 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2946 bit on error, so check for odd return values, not non-0 return
2948 (VMS_get_member_info): Calculate the timezone differences correctly.
2949 Reported by John Fowler <jfowler@nyx.net>.
2952 2001-03-14 Paul D. Smith <psmith@gnu.org>
2954 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2955 value before invoking define_variable().
2956 Reported by John Fowler <jfowler@nyx.net>.
2958 2001-02-07 Paul D. Smith <psmith@gnu.org>
2960 * read.c (record_target_var): If we reset the variable due to a
2961 command-line variable setting overriding it, turn off the "append"
2964 2001-01-17 Paul D. Smith <psmith@gnu.org>
2966 * variable.c (lookup_variable) [VMS]: When getting values from the
2967 environment, allocate enough space for the _value_ plus escapes,
2968 not enough space for the name plus escapes :-/.
2969 Reported by John Fowler <jfowler@nyx.net>.
2971 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2972 warnings that make generates, so it doesn't look like an error.
2973 Reported by Karl Berry <karl@gnu.org>.
2976 Fix for PR/2020: Rework appended target-specific variables. I'm
2977 fairly confident this algorithm is finally correct.
2979 * expand.c (allocated_variable_append): Rewrite. Instead of
2980 expanding each appended variable then adding all the expanded
2981 strings together, we append all the unexpanded values going up
2982 through the variable set contexts, then expand the final result.
2983 This behaves just like non-target-specific appended variable
2984 values, while the old way didn't in various corner cases.
2985 (variable_append): New function: recursively append the unexpanded
2986 value of a variable, walking from the outermost variable scope to
2988 * variable.c (lookup_variable): Remove the code that looked up the
2989 variable set list if the found variable was "append". We don't
2991 (lookup_variable_in_set): Make this non-static so we can use it
2993 (try_variable_definition): Use lookup_variable_in_set() rather
2994 than faking out current_variable_set_list by hand (cleanup).
2995 * variable.h: Add a prototype for the now non-static
2996 lookup_variable_in_set().
2998 2000-11-17 Paul D. Smith <psmith@gnu.org>
3000 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3001 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3002 before throwing a fit.
3004 2000-11-17 Paul D. Smith <psmith@gnu.org>
3006 * read.c (readline): CRLF calculations had a hole, if you hit the
3007 buffer grow scenario just right. Reworked the algorithm to avoid
3008 the need for len or lastlen at all. Problem description with
3009 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3011 2000-10-24 Paul D. Smith <psmith@gnu.org>
3013 * gettext.c (SWAP): Declare this with the prototype, otherwise
3014 some systems don't work (non-32-bit? Reported for Cray T3E).
3015 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3017 2000-10-05 Paul D. Smith <psmith@gnu.org>
3019 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3020 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3022 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3024 2000-09-22 Paul D. Smith <psmith@gnu.org>
3026 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3027 parts of the real gettext.h here, and we expect to really include
3028 the real gettext.h later. If we keep this #define, it's ignored.
3030 2000-09-21 Paul D. Smith <psmith@gnu.org>
3032 * main.c (log_working_directory): Rework the text to use complete
3033 sentences, to make life simpler for the translators.
3035 2000-08-29 Paul D. Smith <psmith@gnu.org>
3037 * file.c (remove_intermediates): Print a debug message before we
3038 remove intermediate files, so the user (if she uses -d) knows
3041 2000-08-21 Paul D. Smith <psmith@gnu.org>
3043 * variable.c (try_variable_definition): Change how we handle
3044 target-specific append variable defns: instead of just setting the
3045 value, expand it as an append _but_ only within the current
3046 target's context. Otherwise we lose all but the last value if the
3047 variable is appended more than once within the current target
3048 context. Fixes PR/1831.
3050 2000-08-16 Paul D. Smith <psmith@gnu.org>
3052 * function.c (func_shell): Nul-terminate the buffer before
3053 printing an exec error message (just in case it's not!).
3054 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3056 2000-07-25 Paul D. Smith <psmith@gnu.org>
3058 * job.c (construct_command_argv_internal): Add "~" to the list of
3059 sh_chars[] which disallow optimizing out the shell call.
3061 2000-07-23 Paul Eggert <eggert@twinsun.com>
3063 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3064 supersedes --disable-nsec-timestamps.
3065 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3066 * README: Remove --disable-nsec-timestamps.
3068 * filedef.h (struct file.low_resolution_time): New member.
3069 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3070 * remake.c (update_file_1):
3071 Avoid spurious rebuilds due to low resolution time stamps,
3072 generalizing the earlier code that applied only to archive members.
3073 (f_mtime): Archive members always have low resolution time stamps.
3075 * configure.in: Remove --disable-nsec-timestamps, as this has
3076 been superseded by .LOW_RESOLUTION_TIME.
3078 2000-07-23 Paul Eggert <eggert@twinsun.com>
3080 * configure.in (enable_nsec_timestamps): Renamed from
3081 make_cv_nsec_timestamps, since enable/disable options
3082 shouldn't be cached.
3084 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3085 and Paul Eggert <eggert@twinsun.com>
3087 * file.c (file_timestamp_now):
3088 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3089 so that clock_gettime is not linked unless needed.
3091 * filedef.h (FILE_TIMESTAMP_HI_RES):
3092 Remove definition; "configure" now does this.
3094 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3095 to before high resolution file timestamp check,
3096 since that check now uses uintmax_t.
3097 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3098 high resolution file timestamps.
3099 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3100 so that we don't link in clock_gettime unnecessarily.
3102 2000-07-17 Paul D. Smith <psmith@gnu.org>
3104 * i18n/ja.po: New version of the translation file.
3106 2000-07-07 Paul D. Smith <psmith@gnu.org>
3108 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3109 the offset calculation.
3110 (name_mtime): Replace EINTR test with EINTR_SET macro.
3112 2000-07-07 Paul Eggert <eggert@twinsun.com>
3116 * remake.c (update_file_1):
3117 Avoid spurious rebuilds of archive members due to their
3118 timestamp resolution being only one second.
3119 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3120 the clock's resolution being lower than file timestamps'.
3121 When warning about future timestamps, report only the discrepancy,
3122 not the absolute value of the timestamp and the current time.
3124 * file.c (file_timestamp_now): New arg RESOLUTION.
3125 * filedef.h (file_timestamp_now): Likewise.
3126 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3128 2000-07-05 Paul D. Smith <psmith@gnu.org>
3130 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3131 to listp. Fixes PR/1793.
3133 2000-06-26 Paul Eggert <eggert@twinsun.com>
3135 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3137 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.

3141 2000-06-25 Martin Buchholz <martin@xemacs.org>
3143 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.

3146 2000-06-23 Paul D. Smith <psmith@gnu.org>
3148 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3149 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3150 * make.h: Define these macros.
3152 * Version 3.79.1 released.
3154 * configure.in: Add a new option, --disable-nsec-timestamps, to
3155 avoid using sub-second timestamps on systems that support it. It
3156 can lead to problems, e.g. if your makefile relies on "cp -p".
3157 * README.template: Document the issue with "cp -p".
3159 * config.guess, config.sub: Updated.
