3 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
4 pathnames, with const strings.
5 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
6 from the template (used for building from CVS, not a dist).
8 2007-10-10 Paul Smith <psmith@gnu.org>
10 * make.h: Add a prototype for w32_kill() (change suggested by
11 Yongwei Wu <wuyongwei@gmail.com>).
13 2007-08-15 Paul Smith <psmith@gnu.org>
15 * doc/make.texi (GNU Free Documentation License): The fdl.texi
16 file has had the section info removed, so add some to make.texi
19 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
21 * remake.c (check_dep): Reset the target state for intermediate
22 files. They might have been considered before but not updated
23 then (order-only for example) but they will be this time.
24 Fixes Savannah bug #'s 3330 and 15919.
26 2007-07-13 Paul Smith <psmith@gnu.org>
28 * file.c (expand_deps): Use variable_buffer as the start of the

47 "Expansion of a deferred"
48 Fixes Savannah bug #20018.
50 * expand.c (variable_expand_for_file): Preserve the value of
51 reading_file rather than setting it to 0 at the end.
52 Fixes Savannah bug #20033.
54 2007-05-11 Paul Smith <psmith@gnu.org>

68 Dave Korn <dave.korn@artimi.com>
70 2007-05-08 Paul Smith <psmith@gnu.org>
72 Fix Savannah bug #19656:
74 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
76 * make.h: Change all case-insensitive string compares to use
77 strcasecmp() (from POSIX). If we don't have that but do have one
78 of the others, define strcasecmp to be one of those instead. If
79 we don't have any, declare a prototype for our own version.
81 * misc.c (strcasecmp): Use this if we can't find any native
82 case-insensitive string comparison function.
83 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
84 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
86 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
87 strcasecmp() instead of stricmp().
88 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
90 * acinclude.m4: Remove the strcasecmp() check from here.
92 2007-03-21 Paul Smith <psmith@gnu.org>
94 * configure.in: Don't turn on case-insensitive file system support
95 if --disable-... is given. Fixes Savannah bug #19348.
97 2007-03-19 Paul Smith <psmith@gnu.org>
99 * ALL: Use the strcache for all file name strings, or other
100 strings which we will never free. The goal is to save memory by
101 avoiding duplicate copies of strings. However, at the moment this
102 doesn't save much memory in most situations: due to secondary
103 expansion we actually save prerequisite lists twice (once before
104 the secondary expansion, and then again after it's been parsed
105 into individual file names in the dep list). We will resolve this
106 in a future change, by doing the parsing up-front for targets
107 where secondary expansion is not set.
109 Moving things into the strcache also allows us to use const
110 pointers in many more places.
112 2007-01-03 Paul Smith <psmith@gnu.org>
114 * make.h (ENULLLOOP): Reset errno after each failed invocation of
115 the function, not just the first. Fixes Savannah bug #18680.
117 2006-11-18 Paul Smith <psmith@gnu.org>
119 * strcache.c (strcache_add_len): Don't allocate a new buffer
120 unless the string is not already nil-terminated. Technically this
121 is a violation of the standard, since we may be passed an array
122 that is not long enough to test one past. However, in make this
123 is never true since we only use nil-terminated strings or
126 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
128 * main.c: New global cmd_prefix, defaults to '\t'.
129 * job.c (construct_command_argv_internal): Use cmd_prefix instead
133 (dir_contents_file_exists_p): Check for an error return from
134 readdir(), just in case.
136 * commands.c: Constified.
137 * default.c: Constified.
138 * expand.c: Constified.
139 * function.c: Partial constification.
140 * variable.c: Partial constification.
141 * vmsify.c: Constification. Hard to test this but I hope I didn't
143 * vpath.c: Partial constification.
144 * w32/pathstuff.c: Partial constification.
146 2006-11-16 Eli Zaretskii <eliz@gnu.org>
148 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
149 backslashes and drive letters as absolute.
151 2006-10-22 Paul Smith <psmith@gnu.org>
153 * main.c (struct command_switch): Use const and void*.
155 2006-10-21 Paul Smith <psmith@gnu.org>
158 * arscan.c: Constified.
160 2006-09-30 Paul Smith <psmith@gnu.org>
162 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
163 point to lastword since the example was updated.
164 Fixes Savannah bug #16304.
165 (Secondary Expansion): Correct example description.
166 Fixes Savannah bug #16468.
167 (Makefile Contents): Clarify that comments cannot appear within
168 variable references or function calls.
169 Fixes Savannah bug #16577.
170 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
171 Fixes Savannah bug #17701.
172 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
173 (Prerequisite Types): Added an example of using order-only
174 prerequisites. Fixes Savannah bug #17880.

216 * README.cvs: Add a reminder to notify the GNU translation robot.
218 * doc/make.texi: Change @direcategory (requested by Karl Berry).
220 2006-04-20 Paul D. Smith <psmith@gnu.org>
222 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
223 that don't have extended grep.
224 (cvsclean): Use $(PERL) instead of perl.
226 2006-04-09 Paul D. Smith <psmith@gnu.org>
228 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
230 * expand.c, implicit.c, main.c, read.c: Rename variables so that
231 inner-scope variables don't mask outer-scope variables.
233 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

292 Declare and define sh_chars_sh[].
294 2006-03-23 Paul D. Smith <psmith@gnu.org>
296 * configure.in: Look for build.sh.in in $srcdir so it will be
297 built for remote configurations as well.
299 * Makefile.am: Make sure to clean up build.sh during distclean.
300 Fixes Savannah bug #16166.
302 * misc.c (log_access): Takes a const char *.

353 (allocated_variable_append): Don't expand the final result.
354 Fixes Savannah bug #15913.
356 2006-03-09 Paul Smith <psmith@gnu.org>
358 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
359 listed non-existent files as changed. Turns out there's a bug in
360 the Linux kernel builds which means that this change causes
361 everything to rebuild every time. We will re-introduce this fix
362 in the next release, to give them time to fix their build system.
363 Fixes Savannah bug #16002.
364 Introduces Savannah bug #16051.
366 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
367 we *don't* find UNIX "/".

383 * commands.c (set_file_variables): Realloc, not malloc, the static
384 string values to avoid memory leaks.
386 * expand.c (recursively_expand_for_file): Only set reading_file to
387 an initialized value.
389 * implicit.c (pattern_search): We need to make a copy of the stem
390 if we get it from an intermediate dep, since those get freed.

401 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
402 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
403 the calls to _beginthreadex.
405 * expand.c (recursively_expand_for_file): Initialize `save' to
406 prevent compiler warnings.
408 2006-02-18 Eli Zaretskii <eliz@gnu.org>
410 * job.c (construct_command_argv_internal): Don't create a temporary
411 script/batch file if we are under -n. Call _setmode to switch the
412 script file stream to text mode.

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

423 2006-02-15 Paul D. Smith <psmith@gnu.org>
425 Fix for Savannah bug #106.
427 * expand.c (expanding_var): Keep track of which variable we're
428 expanding. If no variable is being expanded, it's the same as
430 * make.h (expanding_var): Declare it.
431 * expand.c (recursively_expand_for_file): Set expanding_var to the
432 current variable we're expanding, unless there's no file info in
433 it (could happen if it comes from the command line or a default
434 variable). Restore it before we exit.

436 info instead of the reading_file info.

447 empty string we still need to free the allocated buffer.
449 * implicit.c (pattern_search): If we allocated a variable set for
450 an impossible file, free it.
451 * variable.c (free_variable_set): New function.
452 * variable.h: Declare it.
454 * read.c (read_all_makefiles): Makefile names are kept in the
455 strcache, so there's never any need to alloc/free them.
458 * main.c (main): Add "archives" to the .FEATURES variable if
459 archive support is enabled.
460 * doc/make.texi (Special Variables): Document it.

470 * (ALL FILES): Updated copyright and license notices.
472 2006-02-10 Paul D. Smith <psmith@gnu.org>
474 A new internal capability: the string cache is a read-only cache
475 of strings, with a hash table interface for fast lookup. Nothing
476 in the cache will ever be freed, so there's no need for reference
477 counting, etc. This is the beginning of a full solution for
478 Savannah bug #15182, but for now we only store makefile names here.
480 * strcache.c: New file. Implement a read-only string cache.
481 * make.h: Add prototypes for new functions.
482 * main.c (initialize_global_hash_tables): Initialize the string cache.
483 (print_data_base): Print string cache stats.

489 * dir.c (dir_contents_file_exists_p): Don't opendir if the
490 directory time stamp didn't change, except on FAT filesystems.
491 Suggested by J. David Bryan <jdbryan@acm.org>.

512 * vpath.c (selective_vpath_search): If the file we find has a
513 timestamp from -o or -W, use that instead of the real time.
514 * remake.c (f_mtime): If the mtime is a special token from -o or
515 -W, don't overwrite it with the real mtime.

533 Fixes Savannah bug #15533.
534 * filedef.h (struct file): Add a new LAST pointer.
536 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do

559 * main.c: Update the copyright year in the version output.
560 * prepare_w32.bat: Remove this file from the distribution.
562 2006-01-21 Eli Zaretskii <eliz@gnu.org>
564 * remake.c (update_goal_chain): Set g->changed instead of
565 incrementing it, as it is only 8-bit wide, and could overflow if
566 many commands got started in update_file.
568 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
570 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
571 MAXIMUM_WAIT_OBJECTS.
572 (process_wait_for_any_private): Change dimension of handles[]
573 array to MAXIMUM_WAIT_OBJECTS.
574 (process_used_slots): New function.
575 (process_register): Don't register more processes than the
576 available number of slots.
577 (process_easy): Don't start new processes if all slots are used up.
579 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
580 are already more children than sub_proc.c can handle, behave as if
581 the load were too high.
582 (start_job_command): Fix a typo in error message when process_easy
585 2006-01-14 Eli Zaretskii <eliz@gnu.org>
587 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
588 the shell is not sh.exe.
590 * job.c (create_batch_file): Renamed from create_batch_filename;
591 all callers changed. Don't close the temporary file; return its
592 file descriptor instead. New arg FD allows to return the file
594 (construct_command_argv_internal): Use _fdopen instead of fopen to
597 2006-01-04 Paul D. Smith <psmith@gnu.org>
599 * readme.vms: Updates for case-insensitive VMS file systems from
600 Hartmut Becker <Hartmut.Becker@hp.com>.

603 * vmsfunctions.c (readdir): Ditto.
605 * make.1: Add a section on the exit codes for make.
607 * doc/make.texi: A number of minor updates to the documentation.
609 2006-01-03 Paul D. Smith <psmith@gnu.org>
611 * remake.c (update_file_1): Mark a prerequisite changed if it
614 * read.c (eval): Be sure to strip off trailing whitespace from the
615 prerequisites list properly. Also, initialize all fields in
616 struct dep when creating a new one.
618 2005-12-28 Paul D. Smith <psmith@gnu.org>
620 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
621 disable warnings for MSC.
622 Patch by Rob Tulloh <rtulloh@yahoo.com>.
624 2005-12-17 Eli Zaretskii <eliz@gnu.org>
626 * doc/make.texi (Execution): Add a footnote about changes in
627 handling of backslash-newline sequences. Mention the differences
628 on MS-DOS and MS-Windows.
630 * NEWS: More details about building the MinGW port and a pointer
631 to README.W32. Fix the section name that describes the new
632 backward-incompatible processing of backslash-newline sequences.
633 The special processing of SHELL set to "cmd" is only relevant to
634 MS-Windows, not MS-DOS.
636 2005-12-17 Eli Zaretskii <eliz@gnu.org>
638 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
639 to DWORD, to avoid compiler warnings.
640 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
641 use %ld in format, to avoid compiler warnings.
643 * doc/make.texi (Special Targets): Fix a typo.
644 (Appending): Fix cross-reference to Setting.
645 (Special Variables, Secondary Expansion, File Name Functions)
646 (Flavor Function, Pattern Match, Quick Reference): Ensure two
647 periods after a sentence.
648 (Execution): Add @: after "e.g.".
649 (Environment): Fix punctuation.
650 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
651 (Shell Function, Target-specific): Add @: after "vs."
653 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
655 * read.c (record_target_var): Initialize variable's export field
656 with v_default instead of leaving it "initialized" by whatever
657 garbage happened to be on the heap.
659 2005-12-12 Paul D. Smith <psmith@gnu.org>
661 * make.1: Fix some display errors and document all existing options.
662 Patch provided by Mike Frysinger <vapier@gentoo.org>.
664 2005-12-11 Paul D. Smith <psmith@gnu.org>
666 * implicit.c (pattern_search): If 2nd expansion is not set for
667 this implicit rule, replace the pattern with the stem directly,
668 and don't re-expand the variable list. Along with the other
669 .SECONDEXPANSION changes below, fixes bug #13781.
671 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
673 * implicit.c (pattern_search): Mark other files that this rule
674 builds as targets so that they are not treated as intermediates
675 by the pattern rule search algorithm. Fixes bug #13022.
677 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
679 * remake.c (notice_finished_file): Propagate the change of
680 modification time to all the double-colon entries only if
681 it is the last one to be updated. Fixes bug #14334.
683 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
685 * function.c (func_flavor): Implement the flavor function which
686 returns the flavor of a variable.
687 * doc/make.texi (Functions for Transforming Text): Document it.
688 * NEWS: Add it to the list of new functions.
690 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
692 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
694 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
695 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
697 2005-10-26 Paul Smith <psmith@gnu.org>
699 * read.c (record_files): Don't set deps flags if there are no deps.
700 * maintMakefile: We only need to build the templates when we are
701 creating a distribution, so don't do it for "all".
703 2005-10-24 Paul D. Smith <psmith@gnu.org>
705 Make secondary expansion optional: its enabled by declaring the
706 special target .SECONDEXPANSION.
708 * NEWS: Update information on second expansion capabilities.
709 * doc/make.texi (Secondary Expansion): Document the
710 .SECONDEXPANSION special target and its behavior.
711 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
712 prerequisite list was found in a static pattern rule.
713 (free_dep_chain): Declare a prototype.
714 * file.c (parse_prereqs): New function: break out some complexity
716 (expand_deps): If we aren't doing second expansion, replace % with
717 the stem for static pattern rules. Call the new function.
718 * filedef.h (parse_prereqs): Declare a prototype.
719 * implicit.c (pattern_search): Initialize the new staticpattern
721 * main.c (second_expansion): Declare a global variable to remember
722 if the special target has been seen. Initialize the new
723 staticpattern field for prerequisites.
724 * make.h: Extern for second_expansion.
725 * misc.c (free_dep_chain): New function: frees a struct dep list.
726 * read.c (read_all_makefiles): Initialize the staticpattern field.
727 (eval_makefile): Ditto.
728 (record_files): Check for the .SECONDEXPANSION target and set
729 second_expansion global if it's found.
730 Use the new free_dep_chain() instead of doing it by hand.
731 Set the staticpattern field for prereqs of static pattern targets.
733 2005-10-16 Paul D. Smith <psmith@gnu.org>
735 * main.c (main): Set CURDIR to be a file variable instead of a
736 default, so that values of CURDIR inherited from the environment
737 won't override the make value.
739 2005-09-26 Paul D. Smith <psmith@gnu.org>
741 * job.c (construct_command_argv_internal): If the line is empty
742 remember to free the temporary argv strings.
745 2005-09-16 Paul D. Smith <psmith@gnu.org>
747 * job.c (start_job_command): The noerror flag is a boolean (single
748 bit); set it appropriately.
749 Reported by Mark Eichin <eichin@metacarta.com>
751 2005-08-29 Paul D. Smith <psmith@gnu.org>
753 * function.c (func_error): On Windows, output from $(info ...)
754 seems to come in the wrong order. Try to force it with fflush().
756 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
758 * read.c (record_files): Move code that sets stem for static
759 pattern rules out of the if (!two_colon) condition so it is
760 also executed for two-colon rules. Fixes Savannah bug #13881.
762 2005-08-08 Paul D. Smith <psmith@gnu.org>
764 * make.h: Don't test that __STDC__ is non-0. Some compilers
765 (Windows for example) set it to 0 to denote "ISO C + extensions".
768 2005-08-07 Paul D. Smith <psmith@gnu.org>
770 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
771 conditional (slightly different version of a fix from Eli).
773 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
774 If make is running in parallel without -k and two jobs die in a
775 row, but not too close to each other, then make will quit without
776 waiting for the rest of the jobs to die.
778 * main.c (die): Don't reset err before calling reap_children() the
779 second time: we still want it to be in the error condition.
780 * job.c (reap_children): Use a static variable, rather than err,
781 to control whether or not the error message should be printed.
783 2005-08-06 Eli Zaretskii <eliz@gnu.org>
785 * w32/subproc/sub_proc.c: Include signal.h.
786 (process_pipe_io, process_file_io): Pass a pointer to a local
787 DWORD variable to GetExitCodeProcess. If the exit code is
788 CONTROL_C_EXIT, put SIGINT into pproc->signal.
790 * job.c [WINDOWS32]: Include windows.h.
791 (main_thread) [WINDOWS32]: New global variable.
792 (reap_children) [WINDOWS32]: Get the handle for the main thread
793 and store it in main_thread.
795 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
796 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
797 doing anything else. When we are done, close the main thread
798 handle and exit with status 130.
800 2005-07-30 Eli Zaretskii <eliz@gnu.org>
802 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
805 * main.c (find_and_set_default_shell): If found a DOSish shell,
806 set sh_found and the value of default_shell, and report the
807 findings in debug mode.
809 * job.c (construct_command_argv_internal): Check unixy_shell, not
810 no_default_sh_exe, to decide whether to use Unixy or DOSish
813 * README.W32: Update with info about the MinGW build.
815 * build_w32.bat: Support MinGW.
817 * w32/subproc/build.bat: Likewise.
819 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
822 * function.c (windows32_openpipe): Fix format strings for printing
825 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
827 (start_job_command): Fix format string for printing the result of
829 (start_job_command) [WINDOWS32]: Do not define.
830 (exec_command): Fix format string for printing HANDLE args.
832 * main.c (handle_runtime_exceptions): Fix sprintf format strings
833 to avoid compiler warnings.
834 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
835 (Note: some of these fixes were submitted independently by J. Grant)
837 2005-07-30 J. Grant <jg@jguk.org>
839 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
840 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
841 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
843 2005-07-15 Paul Smith <psmith@gnu.org>
845 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
846 we don't have a POSIX shell, then revert to the old
847 backslash-newline behavior (where they are stripped).
850 2005-07-08 Paul D. Smith <psmith@gnu.org>
852 * config.h.W32.template: Reorder to match the standard config.h,
853 for easier comparisons.
854 From J. Grant <jg@jguk.org>
856 * maintMakefile: Remove .dep_segment before overwriting it, in
857 case it's not writable or noclobber is set.
858 * expand.c (variable_expand_string): Cast result of pointer
859 arithmetic to avoid a warning.
860 * main.c (switches): Add full-fledged final initializer.
862 2005-07-06 Paul D. Smith <psmith@gnu.org>
864 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
865 * signame.c (strsignal): If we found _sys_siglist[] or
866 __sys_siglist[] use those instead of sys_siglist[].
867 From Albert Chin <china@thewrittenword.com>
869 2005-07-04 Paul D. Smith <psmith@gnu.org>
871 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
872 globfree(); set up to use the GNU versions.
873 From Martin Zinser <zinser@zinser.no-ip.info>
875 2005-07-03 Paul D. Smith <psmith@gnu.org>
877 From J. Grant <jg@jguk.org>:
879 * README.W32.template: Update the Windows and tested MSVC versions.
880 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
881 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
882 * build_w32.bat: Ditto.
883 * w32/subproc/build.bat: Ditto.
885 2005-06-28 Paul D. Smith <psmith@gnu.org>
887 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
888 declaration was checked but not present.
890 2005-06-27 Paul D. Smith <psmith@gnu.org>
892 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
893 to unsigned long. Fixes Savannah bug #13550.
895 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
896 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
897 Fixes Savannah bug #13551.
899 2005-06-26 Paul D. Smith <psmith@gnu.org>
901 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
902 it if ANSI_STRING is not set.
904 2005-06-25 Paul D. Smith <psmith@gnu.org>
906 * read.c (eval): If no filenames are passed to any of the
907 "include" variants, don't print an error.
908 * doc/make.texi (Include): Document this.
909 Fixes Savannah bug #1761.
911 * job.c (construct_command_argv_internal): Sanitize handling of
912 backslash/newline pairs according to POSIX: that is, keep the
913 backslash-newline in the command script, but remove a following
914 TAB character, if present. In the fast path, make sure that the
915 behavior matches what the shell would do both inside and outside
916 of quotes. In the slow path, quote the backslash and put a
917 literal newline in the string.
918 Fixes Savannah bug #1332.
919 * doc/make.texi (Execution): Document the new behavior and give
921 * NEWS: Make a note of the new behavior.
923 * make.h [WINDOWS32]: #include <direct.h>.
924 Fixes Savannah bug #13478.
926 * remake.c (name_mtime): If the stat() of a file fails and the -L
927 option was given and the file is a symlink, take the best mtime of
928 the symlink we can get as the mtime of the file and don't fail.
929 Fixes Savannah bug #13280.
931 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
932 If it's set, then don't stop on STOPCHARs or BLANKs if they're
933 inside a variable reference. Make this function static as it's
935 (eval): Call find_char_unquote() with IGNOREVARS set when we're
936 parsing an unexpanded line looking for semicolons.
937 Fixes Savannah bug #1454.
938 * misc.c (remove_comments): Move this to read.c and make it static
939 as it's only used there. Call find_char_unquote() with new arg.
940 * make.h: Remove prototypes for find_char_unquote() and
941 remove_comments() since they're static now.
943 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
944 its export flag and obtain its value. When we need to re-exec,
945 increment the value and add it into the environment.
946 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
947 * NEWS: Mention MAKE_RESTARTS.
948 * main.c (always_make_set): New variable. Change the -B option to
949 set this one instead.
950 (main): When checking makefiles, only set always_make_flag if
951 always_make_set is set AND the restarts flag is 0. When building
952 normal targets, set it IFF always_make_set is set.
953 (main): Avoid infinite recursion with -W, too: only set what-if
954 files to NEW before we check makefiles if we've never restarted
955 before. If we have restarted, set what-if files to NEW _after_ we
957 Fixes Savannah bug #7566:
959 2005-06-17 Paul D. Smith <psmith@gnu.org>
961 * default.c: Change VMS implicit rules to use $$$$ instead of $$
962 in the prerequisites list.
964 2005-06-12 Paul D. Smith <psmith@gnu.org>
966 Fix Savannah bug # 1328.
968 * configure.in: Check for atexit().
969 * misc.c (close_stdout): Test stdout to see if writes to it have
970 failed. If so, be sure to exit with a non-0 error code. Based on
971 code found in gnulib.
973 * main.c (main): Install close_stdout() with atexit().
975 2005-06-10 Paul D. Smith <psmith@gnu.org>
977 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
979 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
980 headers; make vmsWaitForChildren() static; extern vmsify().
981 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
982 Don't create child_execute_job() here (it's in vmsjobs.c).
983 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
985 2005-06-09 Paul D. Smith <psmith@gnu.org>
987 * variable.c (push_new_variable_scope): File variables point
988 directly to the global_setlist variable. So, inserting a new
989 scope in front of that has no effect on those variables: they
990 don't go through current_variable_set_list. If we're pushing a
991 scope and the current scope is global, push it "the other way" so
992 that the new setlist is in the global_setlist variable, and
993 next points to a new setlist with the global variable set.
994 (pop_variable_scope): Properly undo a push with the new
996 Fixes Savannah bug #11913.
998 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1000 * job.c (reap_children): Don't die of the command failed but
1001 the dontcare flag is set. Fixes Savannah bug #13216.
1003 * implicit.c (pattern_search): When creating a target from
1004 an implicit rule match, lookup pattern target and set precious
1005 flag in a newly created target. Fixes Savannah bug #13218.
1007 2005-05-13 Paul D. Smith <psmith@gnu.org>
1009 Implement "if... else if... endif" syntax.
1011 * read.c (eval): Push all checks for conditional words ("ifeq",
1012 "else", etc.) down into the conditional_line() function.
1013 (conditional_line): Rework to allow "else if..." clause. New
1014 return value -2 for lines which are not conditionals. The
1015 ignoring flag can now also be 2, which means "already parsed a
1016 true branch". If that value is seen no other branch of this
1017 conditional can be considered true. In the else parsing if there
1018 is extra text after the else, invoke conditional_line()
1019 recursively to see if it's another conditional. If not, it's an
1020 error. If so, raise the conditional value to this level instead
1021 of creating a new conditional nesting level. Special check for
1022 "else" and "endif", which aren't allowed on the "else" line.
1023 * doc/make.texi (Conditional Syntax): Document the new syntax.
1025 2005-05-09 Paul D. Smith <psmith@gnu.org>
1027 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1028 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1029 recurses to the w32 directory, even on non-Windows systems. Use
1030 the method suggested in the automake manual.
1031 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1032 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1034 2005-05-07 Paul D. Smith <psmith@gnu.org>
1036 * main.c (die): If we're dying with a fatal error (not that a
1037 command has failed), write back any leftover tokens before we go.
1039 * job.c (set_child_handler_action_flags): If there are jobs
1040 waiting for the load to go down, set an alarm to go off in 1
1041 second. This allows us to wake up from a potentially long-lasting
1042 read() and start a new job if the load has gone down. Turn it off
1044 (job_noop): Dummy signal handler function.
1045 (new_job): Invoke it with the new semantics.
1047 * docs/make.texi: Document secondary expansion. Various cleanups
1050 2005-05-03 Paul D. Smith <psmith@gnu.org>
1052 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1053 the targets which are to ultimately be made are called "goals";
1054 see the GNU make manual. Also, MAKECMDGOALS, etc.
1056 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1057 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1058 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1060 2005-05-02 Paul D. Smith <psmith@gnu.org>
1062 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1063 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1064 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1065 functions to vmsjobs.c. #include it into jobs.c.
1067 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1068 jobserver tokens. I found that this happens when an exported
1069 recursive variable contains a $(shell ...) function reference: in
1070 this situation we could "forget" to write back a token.
1072 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1073 we have. It's not reliable to depend on the number of children in
1074 our linked list so keep a separate count.
1075 (new_job): Check jobserver_tokens rather than children &&
1076 waiting_jobs. Increment jobserver_tokens when we get one.
1077 (free_child): If jobserver_tokens is 0, internal error. If it's
1078 >1, write a token back to the jobserver pipe (we don't write a
1079 token for the "free" job). Decrement jobserver_tokens.
1081 * main.c: Add variable master_job_slots.
1082 (main): Set it to hold the number of jobs requested if we're the
1083 master process, when using the jobserver.
1084 (die): Sanity checks: first test jobserver_tokens to make sure
1085 this process isn't holding any tokens we didn't write back.
1086 Second, if master_job_slots is set count the tokens left in the
1087 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1089 2005-04-24 Paul D. Smith <psmith@gnu.org>
1091 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1092 with -l# can lose jobserver tokens, because waiting jobs are not
1093 consulted properly when checking for the "free" token.
1095 * job.c (free_child): Count waiting_jobs as having tokens.
1096 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1097 handle jobs waiting for the load to drop.
1099 2005-04-23 Paul D. Smith <psmith@gnu.org>
1101 * main.c (main): Be careful to not core if a variable setting in
1102 the environment doesn't contain an '='. This is illegal but can
1103 happen in broken setups.
1104 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1106 2005-04-12 Paul D. Smith <psmith@gnu.org>
1108 The second expansion feature causes significant slowdown. Timing
1109 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1110 read the makefile before the feature, to 11+s to do the same
1111 operations after the feature. Additionally, memory usage
1112 increased drastically. To fix this I added some intelligence that
1113 avoids the overhead of the second expansion unless it's required.
1115 * dep.h: Add a new boolean field, need_2nd_expansion.
1117 * read.c (eval): When creating the struct dep for the target,
1118 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1119 (record_files): If there's a "%" in a static pattern rule, it gets
1120 converted to "$*" so set need_2nd_expansion to 1.
1122 * file.c (expand_deps): Rework to be more efficient. Only perform
1123 initialize_file_variables(), set_file_variables(), and
1124 variable_expand_for_file() if the need_2nd_expansion is set.
1126 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1127 (pattern_search): Ditto.
1128 * main.c (handle_non_switch_argument): Ditto.
1130 * read.c (read_all_makefiles): Ditto.
1131 (eval_makefile): Ditto.
1133 2005-04-07 Paul D. Smith <psmith@gnu.org>
1135 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1136 * variable.c (sync_Path_environment): Ditto.
1137 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1139 * main.c (main): Define the .FEATURES variable.
1140 * NEWS: Announce .FEATURES.
1141 * doc/make.texi (Special Variables): Document .FEATURES.
1143 * remake.c (check_dep): If a file is .PHONY, update it even if
1144 it's marked intermediate. Fixes Savannah bug #12331.
1146 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1148 * file.c (expand_deps): Factor out the second expansion and
1149 prerequisite line parsing logic from snap_deps().
1151 * file.c (snap_deps): Use expand_deps(). Expand and parse
1152 prerequisites of the .SUFFIXES special target first. Fixes
1153 Savannah bug #12320.
1155 2005-03-13 Paul D. Smith <psmith@gnu.org>
1157 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1160 2005-03-11 Paul D. Smith <psmith@gnu.org>
1162 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1163 available, not undefined (from Earnie Boyd).
1165 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1167 * implicit.c (pattern_search): Mark an intermediate target as
1168 precious if it happened to be a prerequisite of some (other)
1169 target. Fixes Savannah bug #12267.
1171 2005-03-09 Paul D. Smith <psmith@gnu.org>
1173 * read.c (eval_makefile): Add alloca(0).
1174 (eval_buffer): Ditto.
1176 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1178 * main.c (main): Use o_file instead of o_default when defining
1179 the .DEFAULT_TARGET special variable.
1180 * read.c (eval): Use define_variable_global() instead of
1181 define_variable() when setting new value for the .DEFAULT_TARGET
1182 special variable. Fixes Savannah bug #12266.
1184 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1186 * imlicit.c (pattern_search): Mark files for which an implicit
1187 rule has been found as targets. Fixes Savannah bug #12202.
1189 2005-03-04 Paul D. Smith <psmith@gnu.org>
1192 * doc/make.texi (Automatic Variables): Document $|.
1194 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1196 * read.c (record_files): Instead of substituting % with
1197 actual stem value in dependency list replace it with $*.
1198 This fixes stem triple expansion bug.
1200 * implicit.c (pattern_search): Copy stem to a separate
1201 buffer and make it a properly terminated string. Assign
1202 this buffer instead of STEM (which is not terminated) to
1203 f->stem. Instead of substituting % with actual stem value
1204 in dependency list replace it with $*. This fixes stem
1205 triple expansion bug.
1207 2005-03-01 Paul D. Smith <psmith@gnu.org>
1209 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1210 on Windows, as it takes a handle not a pid. Just exit.
1211 Fix from patch #3679, provided by Alessandro Vesely.
1213 * configure.in: Update check for sys_siglist[] from autoconf manual.
1214 * signame.c (strsignal): Update to use the new autoconf macro.
1216 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1218 * read.c (record_files): Add a check for the list of prerequisites
1219 of a static pattern rule being empty. Fixes Savannah bug #12180.
1221 2005-02-28 Paul D. Smith <psmith@gnu.org>
1223 * doc/make.texi (Text Functions): Update docs to allow the end
1224 ordinal for $(wordlist ...) to be 0.
1225 * function.c (func_wordlist): Fail if the start ordinal for
1226 $(wordlist ...) is <1. Matches documentation.
1227 Resolves Savannah support request #103195.
1229 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1230 previously we were stopping when !-q, exactly the opposite. This
1231 has been wrong since version 1.34, in 1994!
1232 (update_file): If we got an error don't break out to run more
1233 double-colon rules: just return immediately.
1234 Fixes Savannah bug #7144.
1236 2005-02-27 Paul D. Smith <psmith@gnu.org>
1238 * misc.c (end_of_token): Make argument const.
1239 * make.h: Update prototype.
1241 * function.c (abspath, func_realpath, func_abspath): Use
1242 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1243 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1244 * read.c (record_files): Ditto.
1245 * variable.c (do_variable_definition): Ditto.
1247 * function.c (func_error): Create a new function $(info ...) that
1248 simply prints the message to stdout with no extras.
1249 (function_table_init): Add new function to the table.
1250 * NEWS: Add $(info ...) reference.
1251 * doc/make.texi (Make Control Functions): Document it.
1253 New feature: if the system supports symbolic links, and the user
1254 provides the -L/--check-symlink-time flag, then use the latest
1255 mtime between the symlink(s) and the target file.
1257 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1258 readlink(). If both are available, define MAKE_SYMLINKS.
1259 * main.c: New variable: check_symlink_flag.
1260 (usage): Add a line for -L/--check-symlink-times to the help string.
1261 (switches): Add -L/--check-symlink-times command line argument.
1262 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1263 print a warning and disable it again.
1264 * make.h: Declare check_symlink_flag.
1265 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1266 if the file is a symlink then check each link in the chain and
1267 choose the NEWEST mtime we find as the mtime for the file. The
1268 newest mtime might be the file itself!
1269 * NEWS: Add information about this new feature.
1270 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1272 Avoid core dumps described in Savannah bug # 12124:
1274 * file.c: New variable snapped_deps remember whether we've run
1276 (snap_deps): Set it.
1277 * filedef.h: Extern it.
1278 * read.c (record_files): Check snapped_deps; if it's set then
1279 we're trying to eval a new target/prerequisite relationship from
1280 within a command script, which we don't support. Fatal.
1282 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1284 Implementation of the .DEFAULT_TARGET special variable.
1286 * read.c (eval): If necessary, update default_target_name when
1288 * read.c (record_files): Update default_target_file if
1289 default_target_name has changed.
1290 * main.c (default_target_name): Define.
1291 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1292 default_target_name is set use default_target_file as a root
1294 * filedef.h (default_target_name): Declare.
1295 * dep.h (free_dep_chain):
1296 * misc.c (free_dep_chain): Change to operate on struct nameseq
1297 and change name to free_ns_chain.
1298 * file.c (snap_deps): Update to use free_ns_chain.
1300 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1302 Implementation of the second expansion in explicit rules,
1303 static pattern rules and implicit rules.
1305 * read.c (eval): Refrain from chopping up rule's dependencies.
1306 Store them in a struct dep as a single dependency line. Remove
1307 the code that implements SySV-style automatic variables.
1309 * read.c (record_files): Adjust the code that handles static
1310 pattern rules to expand all percents instead of only the first
1311 one. Reverse the order in which dependencies are stored so that
1312 when the second expansion reverses them again they appear in
1313 the makefile order (with some exceptions, see comments in
1314 the code). Remove the code that implements SySV-style automatic
1317 * file.c (snap_deps): Implement the second expansion and chopping
1318 of dependency lines for explicit rules.
1320 * implicit.c (struct idep): Define an auxiliary data type to hold
1321 implicit rule's dependencies after stem substitution and
1324 * implicit.c (free_idep_chain): Implement.
1326 * implicit.c (get_next_word): Implement helper function for
1327 parsing implicit rule's dependency lines into words taking
1328 into account variable expansion requests. Used in the stem
1331 * implicit.c (pattern_search): Implement the second expansion
1332 for implicit rules. Also fixes bug #12091.
1334 * commands.h (set_file_variables): Declare.
1335 * commands.c (set_file_variables): Remove static specifier.
1337 * dep.h (free_dep_chain): Declare.
1338 * misc.c (free_dep_chain): Implement.
1340 * variable.h (variable_expand_for_file): Declare.
1341 * expand.c (variable_expand_for_file): Remove static specifier.
1343 * make.h (strip_whitespace): Declare.
1344 * function.c (strip_whitespace): Remove static specifier.
1346 2005-02-26 Paul D. Smith <psmith@gnu.org>
1348 * main.c (main): Check for ferror() when reading makefiles from stdin.
1349 Apparently some shells in Windows don't close pipes properly and
1352 2005-02-24 Jonathan Grant <jg@jguk.org>
1354 * configure.in: Add MinGW configuration options, and extra w32 code
1356 * Makefile.am: Add MinGW configuration options, and extra w32 code
1358 * main.c: Determine correct program string (after last \ without .exe).
1359 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1361 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1362 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1363 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1364 environment support.
1366 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1368 * function.c (func_shell): When initializing error_prefix, check
1369 that reading file name is not null. This fixes long-standing
1370 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1372 2005-02-09 Paul D. Smith <psmith@gnu.org>
1374 * maintMakefile: Update the CVS download URL to simplify them.
1375 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1376 downloading the .texi files from Savannah now.
1378 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1380 * main.c (handle_non_switch_argument): Only add variables to
1381 command_variables if they're not already there: duplicate settings
1382 waste space and can be confusing to read.
1384 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1385 this header is never included by non-WINDOWS32 code, and it
1386 requires <config.h> to define which isn't always included first.
1388 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1389 testing MINGW32 versions.
1391 * main.c (log_working_directory): flush stdout to be sure the WD
1392 change is printed before any stderr messages show up.
1394 2005-02-01 Paul D. Smith <psmith@gnu.org>
1396 * maintMakefile (po_repo): Update the GNU translation site URL.
1398 2004-12-01 Paul D. Smith <psmith@gnu.org>
1400 * main.c (main): Change char* env_shell to struct variable shell_var.
1401 * variable.c (target_environment): Use new shell_var.
1403 2004-11-30 Paul D. Smith <psmith@gnu.org>
1405 * configure.in: The old way we avoided creating build.sh from
1406 build.sh.in before build.sh.in exists doesn't work anymore; we
1407 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1408 the help!). This also keeps automake from complaining.
1409 * Makefile.am (README): Add a dummy target so automake won't
1410 complain that this file doesn't exist when we checkout from CVS.
1411 * maintMakefile (.dep_segment): Rewrite this rule since newer
1412 versions of automake don't provide DEP_FILES.
1414 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1416 Implementation of `realpath' and `abspath' built-in functions.
1418 * configure.in: Check for realpath.
1419 * function.c (abspath): Return an absolute file name that does
1420 not contain any `.' or `..' components, nor repeated `/'.
1421 * function.c (func_abspath): For each name call abspath.
1422 * function.c (func_realpath): For each name call realpath
1423 from libc or delegate to abspath if realpath is not available.
1424 * doc/make.texi (Functions for File Names): Document new functions.
1425 * doc/make.texi (Quick Reference): Ditto.
1427 2004-11-28 Paul D. Smith <psmith@gnu.org>
1429 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1430 arguments. Fixes bug #10252.
1432 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1434 * main.c (main): Set SHELL to v_noexport by default. Remember the
1435 original environment setting of SHELL in the env_shell variable.
1436 * main.h: Export new env_shell variable.
1437 * variable.c (target_environment): If we find a v_noexport
1438 variable for SHELL, add a SHELL variable with the env_shell value.
1439 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1440 * doc/make.texi (Variables/Recursion): Ditto.
1442 2004-11-28 Paul D. Smith <psmith@gnu.org>
1444 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1445 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1446 Patch by Alessandro Vesely.
1448 2004-11-12 Paul D. Smith <psmith@gnu.org>
1450 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1451 the command line if it's inside a string.
1452 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1454 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1456 * function.c (func_lastword): New function: return last word
1457 from the list of words.
1458 * doc/make.texi: Document $(lastword ). Fix broken links in
1459 Quick Reference section.
1461 2004-10-06 Paul D. Smith <psmith@gnu.org>
1463 Apply patch from Alessandro Vesely, provided with bug # 9748.
1464 Fix use of tmpnam() to work with Borland C.
1466 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1467 construction of a temporary filename, and call new function
1468 create_batch_filename().
1469 (create_batch_filename) [WINDOWS32]: New function to create a
1472 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1474 * read.c (record_target_var): Expand simple pattern-specific
1476 * variable.c (initialize_file_variables): Do not expand simple
1477 pattern-specific variable.
1479 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1481 * remake.c (update_file_1): When rebuilding makefiles inherit
1482 dontcare flag from a target that triggered update.
1484 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1486 * variable.c (initialize_file_variables): Mark pattern-specific
1487 variable as a per-target and copy export status.
1489 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1491 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1493 * implicit.c (pattern_search): When considering an implicit rule's
1494 prerequisite check that it is actually a target rather then
1495 just an entry in the file hashtable.
1497 2004-09-21 Paul D. Smith <psmith@gnu.org>
1499 * read.c (readstring): Fix some logic errors in backslash handling.
1500 (eval): Remove some unnecessary processing in buffer handling.
1501 (record_target_var): Assert that parse_variable_definition() succeeded.
1502 Reported by: Markus Mauhart <qwe123@chello.at>.
1504 * misc.c: Removed the sindex() function. All instances of this
1505 function were trivially replaceable by the standard strstr()
1506 function, and that function will always have better (or certainly
1507 no worse) performance than the very simple-minded algorithm
1508 sindex() used. This can matter with complex makefiles.
1509 * make.h: Remove the prototype for sindex().
1510 * function.c (subst_expand): Convert sindex() call to strstr().
1511 This means we no longer need to track the TLEN value so remove that.
1512 (func_findstring): Convert sindex() to strstr().
1513 * commands.c (chop_commands): Convert sindex() calls to strstr().
1514 Suggested by: Markus Mauhart <qwe123@chello.at>.
1516 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1517 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1518 If SHELL is set to CMD.EXE then assume it's batch-mode and
1519 non-unixy. I wrote the code differently from the patch, though,
1520 to make it safer. This also resolves bug #9174.
1522 2004-09-20 Paul D. Smith <psmith@gnu.org>
1524 * expand.c (variable_expand_string): Modify to invoke
1525 patsubst_expand() instead of subst_expand(); the latter didn't
1526 handle suffix patterns correctly.
1527 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1528 was used only from variable_expand_string() and is no longer used
1530 (func_subst): Ditto, on call to subst_expand().
1531 (patsubst_expand): Require the percent pointers to point to the
1532 character after the %, not to the % itself.
1533 * read.c (record_files): New call criteria for patsubst_expand().
1534 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1535 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1537 2004-09-19 Paul D. Smith <psmith@gnu.org>
1539 * function.c (subst_expand): Fix a check in by_word: look for a
1540 previous blank if we're beyond the beginning of the string, not
1541 the beginning of the word.
1542 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1544 2004-05-16 Paul D. Smith <psmith@gnu.org>
1546 * remake.c (update_goal_chain): Change the argument specifying
1547 whether we're rebuilding makefiles to be a global variable,
1548 REBUILDING_MAKEFILES.
1549 (complain): Extract the code that complains about no rules to make
1550 a target into a separate function.
1551 (update_file_1): If we tried to rebuild a file during the makefile
1552 rebuild phase and it was dontcare, then no message was printed.
1553 If we then try to build the same file during the normal build,
1554 print a message this time.
1555 (remake_file): Don't complain about un-remake-able files when
1556 we're rebuilding makefiles.
1558 2004-05-11 Paul D. Smith <psmith@gnu.org>
1560 * job.c (construct_command_argv_internal): OS/2 patches from
1561 Andreas Buening <andreas.buening@nexgo.de>.
1563 2004-05-10 Paul D. Smith <psmith@gnu.org>
1565 * remake.c (update_file): Don't walk the double-colon chain unless
1566 this is a double-colon rule. Fix suggested by Boris Kolpackov
1567 <boris@kolpackov.net>.
1569 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1570 * readme.vms: New section describing OpenVMS support and issues.
1571 * default.c (default_variables): Add support for IA64.
1572 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1573 without some privilege aborts make with the error
1574 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1575 pressing Ctrl+Y and the input device is no terminal. The change
1576 catches this error and just continues.
1578 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1580 2004-04-25 Paul D. Smith <psmith@gnu.org>
1582 * commands.c (set_file_variables): Set $< properly in the face of
1583 order-only prerequisites.
1584 Patch from Boris Kolpackov <boris@kolpackov.net>
1586 2004-04-21 Bob Byrnes <byrnes@curl.com>
1588 * main.c (main): Notice failures to remake makefiles.

1592 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1594 * job.c: No default shell for RISC OS.
1595 (load_too_high): Hard-code the return to 1.
1596 (construct_command_argv_internal): No sh_chars or sh_cmds.
1597 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1599 2004-03-20 Paul D. Smith <psmith@gnu.org>
1601 * variable.c (do_variable_definition): Don't append from the
1602 global set if a previous non-appending target-specific variable
1603 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1606 * expand.c (reference_variable): Don't give up on variables with
1607 no value that have the target-specific append flag set: they might
1608 have a value after all. Reported by Oliver Schmidt
1609 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1610 <nikulin@dx1cmd.inp.nsk.su>.
1612 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1613 refer to absolute pathnames in directories that don't exist: some
1614 portion of the makefile could create those directories before we
1615 match the pattern. Fixes bugs #775 and #108.
1617 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1619 * main.c (main): Free makefile_mtimes if we have any.
1620 * README.W32.template: Update documentation for the current status
1621 of the MS-Windows port.
1622 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1623 environment variable is sometimes already defined which causes the
1625 * main.c (debug_signal_handler): Only define this function if
1626 SIGUSR1 is available.
1628 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1630 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1631 * README.OS2.template: Documentation updates.
1632 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1633 link line for safety.
1634 * maintMakefile (build.sh.in): Remove an extraneous ")".
1635 * job.c (child_execute_job): Close saved FDs.
1636 * job.c (exec_command) [OS/2]: exec_command(): If the command
1637 can't be exec'ed and if the shell is not Unix-sh, then try again
1638 with argv = { "cmd", "/c", ... }. Normally, this code is never
1639 reached for the cmd shell unless the command really doesn't exist.
1640 (construct_command_argv_internal) [OS/2]: The code for cmd
1641 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1642 The CMD builtin commands are case insensitive so use strcasecmp().
1644 2004-03-19 Paul D. Smith <psmith@gnu.org>
1646 * read.c (do_define): Re-order line counter increment so the count
1647 is accurate (we were losing one line per define). Reported by
1648 Dave Yost <Dave@Yost.com>.
1650 2004-03-06 Paul D. Smith <psmith@gnu.org>
1652 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1654 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1655 * misc.c (message,error,fatal): Ditto.
1656 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1657 * config.h.W32.template: Ditto.
1658 * config.h-vms.template: Ditto.
1659 * config.ami.template: Ditto.
1661 2004-03-04 Paul D. Smith <psmith@gnu.org>
1663 * README.template: Add a note about broken /bin/sh on SunOS
1664 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1666 * misc.c (message, error, fatal): Don't use "..." if we're using
1667 varargs. ansi2knr should handle this but it doesn't work: it
1668 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1669 done. On many systems (SunOS for example) va_dcl is a #define.
1670 So, force the use of the non-"..." version on pre-ANSI compilers.
1672 * maintMakefile (sign-dist): Create some rules to help automate
1673 the new GNU ftp upload method.
1675 2004-02-24 Paul D. Smith <psmith@gnu.org>
1677 * config.h.W32.template: Add HAVE_STDARG_H
1678 * config.h-vms.template: Ditto.
1679 * config.ami.template: Ditto.
1681 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1683 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1684 * build_w32.bat: Remove extra "+".
1686 2004-02-23 Paul D. Smith <psmith@gnu.org>
1688 * make.h: Create an UNUSED macro to mark unused parameters.
1689 * (many): Clean up warnings by applying UNUSED, fixing
1690 signed/unsigned incompatibilities, etc.
1692 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1694 * filedef.h: Name the command_state enumeration.
1695 * file.c (set_command_state): Use the enumeration in the function
1698 * configure.in: Explicitly set SET_MAKE to empty, to disable
1699 MAKE=make even when no make already exists. Fix bug #3823.
1701 2004-02-22 Paul D. Smith <psmith@gnu.org>
1703 * maintMakefile: Perl script to clean up all non-CVS files. Use
1704 it on all the subdirectories for the cvs-clean target.
1706 * main.c (decode_switches): Require non-empty strings for all our
1707 string command-line options. Fixes Debian bug # 164165.
1709 * configure.in: Check for stdarg.h and varargs.h.
1710 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1711 for printing messages.
1712 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1717 A number of patches for OS/2 support from Andreas Buening
1718 <andreas.buening@nexgo.de>:
1720 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1721 disable the SIGCHLD handler.
1722 (reap_children) [OS/2]: Remove special handling of job_rfd.
1723 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1724 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1725 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1726 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1727 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1730 2004-02-21 Paul D. Smith <psmith@gnu.org>
1732 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1733 <mail@kristov.de> reports that if process_begin() fails we don't
1734 handle the error condition correctly in all cases.
1735 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1736 to have a newline on the message.
1738 * job.c (construct_command_argv_internal): Add "test" to UNIX
1739 sh_cmds[]. Fixes Savannah bug # 7606.
1741 2004-02-04 Paul D. Smith <psmith@gnu.org>
1743 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1744 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1745 Hartmut Becker <Hartmut.Becker@hp.com>.
1747 2004-01-21 Paul D. Smith <psmith@gnu.org>
1749 * job.c (load_too_high): Implement an algorithm to control the
1750 "thundering herd" problem when using -l to control job creation
1751 via the load average. The system only recomputes the load once a
1752 second but we can start many jobs in a second. To solve this we
1753 keep track of the number of jobs started in the last second and
1754 apply a weight to try to guess what a correct load would be.
1755 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1756 Also fixes bug #4693.
1757 (reap_children): Decrease the job count for this second.
1758 (start_job_command): Increase the job count for this second.
1760 * read.c (conditional_line): Expand the text after ifn?def before
1761 checking to see if it's a single word. Fixes bug #7257.
1763 2004-01-09 Paul D. Smith <psmith@gnu.org>
1765 * file.c (print_file): Recurse to print all targets in
1766 double-colon rules. Fixes bug #4518, reported (with patch) by
1767 Andrew Chatham <chatham@google.com>.
1769 2004-01-07 Paul D. Smith <psmith@gnu.org>
1771 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1772 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1773 AC_FUNC_SETVBUF_REVERSED.
1775 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1776 (MAKE Variable): Fix Savannah bug #4898.
1778 * job.c (construct_command_argv_internal): Add "!" to the list of
1779 shell escape chars. POSIX sh allows it to appear before a
1780 command, to negate the exit code. Fixes bug #6404.
1782 * implicit.c (pattern_search): When matching an implicit rule,
1783 remember which dependencies have the ignore_mtime flag set.
1784 Original fix provided in Savannah patch #2349, by Benoit
1785 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1787 2003-11-22 Paul D. Smith <psmith@gnu.org>
1789 * README.W32.template (Outputs): Clarification on -j with
1790 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1793 2003-11-02 Paul D. Smith <psmith@gnu.org>
1795 * function.c (func_if): Strip all the trailing whitespace from the
1796 condition, then don't expand it. Fixed bug # 5798.
1798 * expand.c (recursively_expand_for_file): If we're expanding a
1799 variable with no file context, then use the variable's context.
1802 2003-10-21 Paul D. Smith <psmith@gnu.org>
1804 * main.c (log_working_directory): Add newlines to printf()s.
1806 * README.cvs: Add a note to ignore warnings during autoreconf.
1808 * maintMakefile (po_repo): Set a new URL for PO file updates.
1809 (get-config/config.guess get-config/config.sub): Get these files
1810 from the Savannah config project instead of ftp.gnu.org.
1812 2003-10-05 Paul Eggert <eggert@twinsun.com>
1814 * main.c (main): Avoid potential subscript error if environ has
1817 2003-08-22 Paul D. Smith <psmith@gnu.org>
1819 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1820 systems which don't yet implement the C89 standard :-/.
1822 2003-07-18 Paul D. Smith <psmith@gnu.org>
1824 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1825 [WINDOWS32]: Initialize hash.
1827 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1829 * dir.c (read_dirstream): Provide a workaround for broken versions of
1830 the MinGW dirent structure.
1832 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1834 * w32/include/dirent.h: Add __MINGW32__ filter.
1836 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1838 * make.h: Add global declaration of *make_host.
1839 * main.c (print_usage): Remove local declaration of *make_host.
1840 (print_version): Display "This program built for ..." after Copyright
1843 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1845 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1846 execution of "makeinfo --html make.texi".
1848 2003-04-30 Paul D. Smith <psmith@gnu.org>
1850 * build.template: Make some changes to maybe allow this script to
1851 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1853 * README.OS2.template: New file for OS/2 support. Original
1854 contributed by Andreas Buening.
1855 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1858 2003-04-19 Paul D. Smith <psmith@gnu.org>
1860 Fix bug #1405: allow a target to match multiple pattern-specific
1863 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1864 variable.c, where they've always belonged.
1865 * rule.h: Move the prototypes and struct pattern_var as well.
1866 * variable.c (initialize_file_variables): Invoke
1867 lookup_pattern_var() in a loop, until no more matches are found.
1868 If a match is found, create a new variable set for the target's
1869 pattern variables. Then merge the contents of each matching
1870 pattern variable set into the target's pattern variable set.
1871 (lookup_pattern_var): Change this function to be usable
1872 in a loop. It takes a starting position: if NULL, start at the
1873 beginning; if non-NULL, start with the pattern variable after that
1874 position, and return the next matching pattern.
1875 (create_pattern_var): Create a unique instance of
1876 pattern-specific variables for every definition in the makefile.
1877 Don't combine the same pattern together. This allows us to
1878 process the variable handling properly even when the same pattern
1879 is used multiple times.
1880 (parse_variable_definition): New function: break out the parsing
1881 of a variable definition line from try_variable_definition.
1882 (try_variable_definition): Call parse_variable_definition to
1884 (print_variable_data_base): Print out pattern-specific variables.
1885 * variable.h (struct variable): Remember when a variable is
1886 conditional. Also remember its flavor.
1887 (struct pattern_var): Instead of keeping a variable set, we just
1888 keep a single variable for each pattern.
1889 * read.c (record_target_var): Each pattern variable contains only a
1890 single variable, not a set, so create it properly.
1891 * doc/make.texi (Pattern-specific): Document the new behavior.
1893 2003-04-17 Paul D. Smith <psmith@gnu.org>
1895 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1896 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1897 file/directory naming rules for VMS so I can't tell whether this
1900 2003-04-09 Paul D. Smith <psmith@gnu.org>
1902 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1903 DOS-style pathnames: backslash separators and drive specifiers.
1905 2003-03-28 Paul D. Smith <psmith@gnu.org>
1907 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1908 the intermediate flag on all targets. Fixes bug #2515.
1910 2003-03-24 Paul D. Smith <psmith@gnu.org>
1912 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1913 Upgrade to autoconf 2.57 and automake 1.7.3.
1915 * job.c: More OS/2 changes from Andreas Buening.
1917 * file.c (print_file): Fix variable initialization.
1920 * remake.c (notice_finished_file):
1922 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1923 some calls (like readdir()) return NULL in valid situations
1924 without resetting errno. Fixes bug #2846.
1926 2003-02-25 Paul D. Smith <psmith@gnu.org>
1928 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1930 * job.c (_is_unixy_shell) [OS/2]: New function.
1931 Set default shell to /bin/sh.
1932 (reap_children): Close the job_rfd pipe here since we don't use a
1934 (set_child_handler_action_flags): define this to empty on OS/2.
1935 (start_job_command): Close the jobserver pipe and use
1936 child_execute_job() instead of fork/exec.
1937 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1938 rather than exec'ing, then reconfigure stdin/stdout.
1939 (exec_command): Rewrite to use spawn instead of exec. Return the
1942 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1943 in DOS. Handle the TEMP environment variable as in DOS. Don't
1944 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1945 use -j in DOS mode. Use child_execute_job() instead of
1948 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1951 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1952 prototypes that return values.
1954 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1956 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1957 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1959 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1962 2003-02-24 Paul D. Smith <psmith@gnu.org>
1964 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1965 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1966 (child_execute_job) [VMS]: Handle error status properly.
1967 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1969 * function.c (func_shell): Use EINTRLOOP() while reading from the
1970 subshell pipe (Fixes bug #2502).
1971 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1973 * main.c (main): Ditto.
1975 2003-01-30 Paul D. Smith <psmith@gnu.org>
1977 * read.c (eval): eval() was not fully reentrant, because the
1978 collapsed buffer was static. Change it to be an automatic
1979 variable so that eval() can be invoked recursively.
1981 (eval): Apply patch # 1022: fix memory reference error on long
1982 target-specific variable lines.
1983 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1985 * function.c (check_numeric): Combine the is_numeric() function
1986 into this function, since it's only called from one place.
1987 Constify this function. Have it print the incorrect string in the
1988 error message. Fixes bug #2407.
1989 (strip_whitespace): Constify.
1990 (func_if): Constify.
1991 * expand.c (expand_argument): Constify.
1993 2003-01-29 Paul D. Smith <psmith@gnu.org>
1995 Fix bug # 2169, also reported by other people on various systems.
1997 * make.h: Some systems, such as Solaris and PTX, do not fully
1998 implement POSIX-compliant SA_RESTART functionality; important
1999 system calls like stat() and readdir() can still fail with EINTR
2000 even if SA_RESTART has been set on the signal handler. So,
2001 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2002 EINTR for system calls which return -1 or 0 (NULL), respectively,
2004 Also, remove the old atomic_stat()/atomic_readdir() and
2005 HAVE_BROKEN_RESTART handling.
2007 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2009 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2010 * remake.c (touch_file): Ditto.
2012 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2013 * read.c (construct_include_path): Ditto.
2014 * remake.c (name_mtime): Ditto.
2015 * vpath.c (selective_vpath_search): Ditto.
2016 * dir.c (find_directory): Ditto.
2017 (local_stat): Ditto.
2018 (find_directory): Use ENULLLOOP() to wrap opendir().
2019 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2021 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2022 atomic_readdir() handling.
2024 2003-01-22 Paul D. Smith <psmith@gnu.org>
2026 * function.c (func_call): Fix Bug #1744. If we're inside a
2027 recursive invocation of $(call ...), mask any of the outer
2028 invocation's arguments that aren't used by this one, so that this
2029 invocation doesn't "inherit" them accidentally.
2031 2002-12-05 Paul D. Smith <psmith@gnu.org>
2033 * function.c (subst_expand): Valery Khamenia reported a
2034 pathological performance hit when doing substitutions on very
2035 large values with lots of words: turns out we were invoking
2036 strlen() a ridiculous number of times. Instead of having each
2037 call to sindex() call strlen() again, keep track of how much of
2038 the text we've seen and pass the length to sindex().
2040 2002-11-19 Paul D. Smith <psmith@gnu.org>
2042 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2045 2002-11-16 Paul D. Smith <psmith@gnu.org>
2047 * NMakefile.template (OBJS): Add hash.c object file.
2048 * SMakefile.template (srcs): Ditto.
2049 * Makefile.ami (objs): Ditto.
2050 * build_w32.bat: Ditto.
2052 * Makefile.DOS.template: Remove extra dependencies.
2054 2002-10-25 Paul D. Smith <psmith@gnu.org>
2056 * expand.c (install_variable_buffer): New function. Install a new
2057 variable_buffer context and return the previous one.
2058 (restore_variable_buffer): New function. Free the current
2059 variable_buffer context and put a previously saved one back.
2060 * variable.h: Prototypes for {install,restore}_variable_buffer.
2061 * function.c (func_eval): Push a new variable_buffer context
2062 before we eval, then restore the old one when we're done.
2065 * read.c (install_conditionals): New function. Install a new
2066 conditional context and return the previous one.
2067 (restore_conditionals): New function. Free the current
2068 conditional context and put a previously saved one back.
2069 (eval): Use the {install,restore}_conditionals for "include"
2071 (eval_buffer): Use {install,restore}_conditionals to preserve the
2072 present conditional state before we evaluate the buffer.
2075 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2077 (Recursion): Add a variable index entry for CURDIR.
2079 * README.cvs: Update to appropriate versions.
2080 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2081 don't need to copy loadavg.c: automake is smart enough to create
2082 it for me. Still have a bug in automake related to ansi2knr tho.
2084 2002-10-14 Paul D. Smith <psmith@gnu.org>
2086 * remake.c (notice_finished_file): Only touch targets if they have
2087 at least one command (as per POSIX). Resolve Bug #1418.
2089 * *.c: Convert to using ANSI C-style function definitions.
2090 * Makefile.am: Enable the ansi2knr feature of automake.
2091 * configure.in: ditto.
2093 2002-10-13 Paul D. Smith <psmith@gnu.org>
2095 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2096 for automatic variable values like $^, etc. In the case of very
2097 large lists of prerequisites this causes problems. Instead reuse
2098 a static buffer (resizeable) for each variable.
2100 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2101 target-specific variable definitions. Check for it and set an
2103 (record_target_var): Set the export field to v_export if the
2104 "exported" flag is set.
2105 * doc/make.texi (Target-specific): Document the ability to use
2108 * doc/make.texi: Change the name of the section on automatic
2109 variables from "Automatic" to "Automatic Variables". Added text
2110 clarifying the scope of automatic variables.
2112 2002-10-04 Paul D. Smith <psmith@gnu.org>
2114 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2116 (record_files): Ditto.
2118 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2119 the search for the '=' to only within the enclosing parens.
2121 2002-10-03 Paul D. Smith <psmith@gnu.org>
2123 Version 3.80 released.
2125 * dir.c: Change hash functions to use K&R function definition style.
2126 * function.c: Ditto.
2128 * variable.c: Ditto.
2130 Update to automake 1.7.
2132 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2133 (pdf): Remove this target as automake now provides one.
2135 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2137 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2139 * makefile.com: Updates for GNU make 3.80.
2140 * makefile.vms: Ditto.
2142 2002-09-23 Paul D. Smith <psmith@gnu.org>
2144 * read.c (enum make_word_type): Remove w_comment.
2145 (get_next_mword): Don't treat comment characters as special; where
2146 this function is used we will never see a comment (it's stripped
2147 before we get here) and treating comments specially means that
2148 targets like "foo\#bar" aren't handled properly.
2150 2002-09-18 Paul D. Smith <psmith@gnu.org>
2152 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2154 * read.c (eval): Expansion of arguments to export/unexport was
2155 ignoring all arguments after the first one. Change the algorithm
2156 to expand the whole line once, then parse the results.
2158 2002-09-17 Paul D. Smith <psmith@gnu.org>
2160 Fix Bug #940 (plus another bug I found while looking at this):
2162 * read.c (record_target_var): enter_file() will add a new entry if
2163 it's a double-colon target: we don't want to do that in this
2164 situation. Invoke lookup_file() and only enter_file() if it does
2165 not already exist. If the file we get back is a double-colon then
2166 add this variable to the "root" double-colon target.
2168 * variable.c (initialize_file_variables): If this file is a
2169 double-colon target but is not the "root" target, then initialize
2170 the root and make the root's variable list the parent of our
2173 2002-09-13 Paul D. Smith <psmith@gnu.org>
2175 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2177 * hash.c (round_up_2): Get rid of a warning.
2179 2002-09-12 Paul D. Smith <psmith@gnu.org>
2181 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2182 so it doesn't complain about getloadavg.c.
2184 * commands.c (set_file_variables): Make sure we always alloca() at
2185 least 1 character for the value of $? (for '\0').
2187 2002-09-11 Paul D. Smith <psmith@gnu.org>
2189 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2190 macro to use RESULT instead of the incorrect _RESULT_.
2192 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2193 and atomic_readdir(). We need to #include dirent.h to get this to
2195 * misc.c (atomic_readdir): Fix typos.
2197 2002-09-10 Paul D. Smith <psmith@gnu.org>
2199 * read.c (eval): Expand variable lists given to export and
2200 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2201 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2203 * doc/make.texi (Variables/Recursion): Document this.
2204 (Conditional Syntax): And here.
2206 2002-09-09 Paul D. Smith <psmith@gnu.org>
2208 * configure.in: Check for memmove().
2210 2002-09-07 Paul D. Smith <psmith@gnu.org>
2212 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2213 Michael Sterrett <msterret@coat.com> reports that while it has
2214 SA_RESTART, it does not work properly.
2216 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2217 that invokes stat() and loops to do it again if it returns EINTR.
2218 (atomic_readdir): Ditto, with readdir().
2220 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2221 and readdir() to atomic_stat() and atomic_readdir().
2223 2002-09-04 Paul D. Smith <psmith@gnu.org>
2225 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2226 reports that GNU make sometimes doesn't recognize that targets can
2227 be made, when directories can be created as prerequisites. He
2228 reports that changing the order of predicates in the DEP->changed
2229 flag test so that lookup_file() is always performed, solves this
2232 2002-08-08 Paul D. Smith <psmith@gnu.org>
2234 * configure.in: Require a newer version of gettext.
2236 * misc.c (perror_with_name): Translate the format string (for
2237 right-to-left language support).
2238 (pfatal_with_name): Ditto.
2240 * main.c: Create a static array of strings to store the usage
2241 text. This is done to facilitate translations.
2242 (struct command_switch): Remove argdesc and description fields.
2243 (switches): Remove values for obsolete fields.
2244 (print_usage): Print each element of the usage array.
2246 * hash.c: Change function definitions to be K&R style.
2248 2002-08-02 Paul D. Smith <psmith@gnu.org>
2250 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2251 this one because it's too hard to get right. We'll look at it for
2253 * main.c (main): Don't create the .TARGETS variable.
2254 * variable.c (handle_special_var): Don't handle .TARGETS.
2256 2002-08-01 Paul D. Smith <psmith@gnu.org>
2258 * main.c (switches): Add a new option, -B (--always-make). If
2259 specified, make will rebuild all targets that it encounters even
2260 if they don't appear to be out of date.
2261 (always_make_flag): New flag.
2262 * make.h: Extern always_make_flag.
2263 * remake.c (update_file_1): Check always_make_flag; if it's set we
2264 will always rebuild any target we can, even if none of its
2265 prerequisites are newer.
2268 * doc/make.texi (Shell Function): Make it clear that make
2269 variables marked as "export" are not passed to instances of the
2272 Add new introspection variable .VARIABLES and .TARGETS.
2274 * variable.c (handle_special_var): New function. If the variable
2275 reference passed in is "special" (.VARIABLES or .TARGETS),
2276 calculate the new value if necessary. .VARIABLES is handled here:
2277 walk through the hash of defined variables and construct a value
2278 which is a list of the names. .TARGETS is handled by
2279 build_target_list().
2280 (lookup_variable): Invoke handle_special_var().
2281 * file.c (build_target_list): Walk through the hask of known files
2282 and construct a list of the names of all the ones marked as
2284 * main.c (main): Initialize them to empty (and as simple variables).
2285 * doc/make.texi (Special Variables): Document them.
2286 * NEWS: Mention them.
2288 * variable.h (struct variable): Add a new flag "exportable" which
2289 is true if the variable name is valid for export.
2290 * variable.c (define_variable_in_set): Set "exportable" when a new
2291 variable is defined.
2292 (target_environment): Use the "exportable" flag instead of
2293 re-checking the name here... an efficiency improvement.
2295 2002-07-31 Paul D. Smith <psmith@gnu.org>
2297 * config.h-vms.template: Updates to build on VMS. Thanks to
2298 Brian_Benning@aksteel.com for helping verify the build.
2299 * makefile.com: Build the new hash.c file.
2300 * hash.h: Use strcpmi(), not stricmp(), in the
2301 HAVE_CASE_INSENSITIVE_FS case.
2303 2002-07-30 Paul D. Smith <psmith@gnu.org>
2305 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2306 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2307 Reported by <Brian_Benning@aksteel.com>.
2309 2002-07-10 Paul D. Smith <psmith@gnu.org>
2311 * variable.c (pop_variable_scope): Remove variable made unused by
2312 new hash infrastructure.
2313 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2314 comparisons as well as name comparisons.
2315 * variable.h: Add a prototype for new hash_init_function_table().
2316 * file.c (lookup_file): Remove variables made unused by new hash
2318 * dir.c (directory_contents_hash_2): Missing return of hash value.
2319 (dir_contents_file_exists_p): Remove variables made unused by new
2320 hash infrastructure.
2323 Installed Greg McGary's integration of the hash functions from the
2324 GNU id-utils package:
2326 2002-07-10 Greg McGary <greg@mcgary.org>
2328 * scripts/functions/filter-out: Add literals to to the
2329 pattern space in order to add complexity, and trigger
2330 use of an internal hash table. Fix documentation strings.
2331 * scripts/targets/INTERMEDIATE: Reverse order of files
2332 passed to expected `rm' command.
2334 2002-07-10 Greg McGary <greg@mcgary.org>

2426 2002-07-10 Paul D. Smith <psmith@gnu.org>
2428 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2429 prerequisite list. A real SysV make will expand the entire
2430 prerequisites list _twice_: we don't do that as it's a big
2431 backward-compatibility problem. We only replace those specific
2434 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2435 references left in the list of prerequisites. Check for .POSIX as
2436 we record targets, so we can disable non-POSIX behavior while
2437 reading makefiles as well as running them.
2438 (eval): Check the prerequisite list to see if we have anything
2439 that looks like a SysV prerequisite variable reference.
2441 2002-07-09 Paul D. Smith <psmith@gnu.org>
2443 * doc/make.texi (Prerequisite Types): Add a new section describing
2444 order-only prerequisites.
2446 * read.c (uniquize_deps): If we have the same file as both a
2447 normal and order-only prereq, get rid of the order-only prereq,
2448 since the normal one supersedes it.
2450 2002-07-08 Paul D. Smith <psmith@gnu.org>
2452 * AUTHORS: Added Greg McGary to the AUTHORS file.
2453 * NEWS: Blurbed order-only prerequisites.
2454 * file.c (print_file): Show order-only deps properly when printing
2457 * maintMakefile: Add "update" targets for wget'ing the latest
2458 versions of various external files. Taken from Makefile.maint in
2461 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2462 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2464 2002-07-07 Paul D. Smith <psmith@gnu.org>
2466 * po/*.po: Remove. We'll use wget to retrieve them at release
2469 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2470 rather than a shell you get an exception. Make sure we look up
2471 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2473 * remake.c (notice_finished_file): Fix handling of -t flag.
2474 Patch provided by Henning Makholm <henning@makholm.net>.
2476 * implicit.c (pattern_search): Some systems apparently run short
2477 of stack space, and using alloca() in this function caused an
2478 overrun. I modified it to use xmalloc() on the two variables
2479 which seemed like they might get large. Fixes Bug #476.
2481 * main.c (print_version): Update copyright notice to conform with
2483 (print_usage): Update help output.
2485 * function.c (func_eval): Create a new make function, $(eval
2486 ...). Expand the arguments, put them into a buffer, then invoke
2487 eval_buffer() on the resulting string.
2488 (func_quote): Create a new function, $(quote VARNAME). Inserts
2489 the value of the variable VARNAME without expanding it any
2492 * read.c (struct ebuffer): Change the linebuffer structure to an
2493 "eval buffer", which can be either a file or a buffer.
2494 (eval_makefile): Move the code in the old read_makefile() which
2495 located a makefile into here: create a struct ebuffer with that
2496 information. Have it invoke the new function eval() with that
2498 (eval_buffer): Create a new function that creates a struct ebuffer
2499 that holds a string buffer instead of a file. Have it invoke
2500 eval() with that ebuffer.
2501 (eval): New function that contains the guts of the old
2502 read_makefile() function: this function parses makefiles. Obtains
2503 data to parse from the provided ebuffer. Some modifications to
2504 make the flow of the function cleaner and clearer. Still could
2505 use some work here...
2506 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2507 contents of the define/endef variable from the ebuffer.
2508 (readstring): Read the next line from a string-style ebuffer.
2509 (readline): Read the next line from an ebuffer. If it's a string
2510 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2513 * dep.h (eval_buffer): Prototype eval_buffer();
2515 * variable.c (do_variable_definition): Make sure that all
2516 non-target-specific variables are registered in the global set.
2517 If we're invoked from an $(eval ...) we might be inside a $(call
2518 ...) or other function which has pushed a variable scope; we still
2519 want to define our variables from evaluated makefile code in the
2522 2002-07-03 Greg McGary <greg@mcgary.org>
2524 * dep.h (struct dep) [ignore_mtime]: New member.
2525 [changed]: convert to a bitfield.
2526 * implicit.c (pattern_search): Zero ignore_mtime.
2527 * main.c (main, handle_non_switch_argument): Likewise.
2528 * rule.c (convert_suffix_rule): Likewise.
2529 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2530 (read_makefile): Parse '|' in prerequisite list.
2531 (uniquize_deps): Consider ignore_mtime when comparing deps.
2532 * remake.c (update_file_1, check_dep): Don't force remake for
2533 dependencies that have d->ignore_mtime.
2534 * commands.c (FILE_LIST_SEPARATOR): New constant.
2535 (set_file_variables): Don't include a
2536 prerequisite in $+, $^ or $? if d->ignore_mtime.
2539 2002-06-18 Paul D. Smith <psmith@gnu.org>
2541 * make.texinfo: Updates for next revision. New date/rev/etc.
2542 Recreate all Info menus. Change license on the manual to the GNU
2543 Free Documentation License. A number of typos.
2544 (Variables Simplify): Don't use "-" before it's defined.
2545 (Automatic Prerequisites): Rewrite the target example to work
2546 properly if the compile fails. Remove incorrect comments about
2547 how "set -e" behaves.
2548 (Text Functions): Move the "word", "wordlist", "words", and
2549 "firstword" functions here, from "File Name Functions".
2550 * make-stds.texi: Update from latest GNU version.
2551 * fdl.texi: (created) Import the latest GNU version.
2553 2002-06-06 Paul D. Smith <psmith@gnu.org>
2555 * variable.c (do_variable_definition): New function: extract the
2556 part of try_variable_definition() that actually sets the value
2557 into a separate function.
2558 (try_variable_definition): Call do_variable_definition() after
2559 parsing the variable definition string.
2560 (define_variable_in_set): Make the name argument const.
2562 * variable.h (enum variable_flavor): Make public.
2563 (do_variable_definition): Create prototype.
2565 * read.c (read_all_makefiles): Create a new built-in variable,
2567 (read_makefile): Add each makefile read in to this variable value.
2569 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2571 * Makefile.DOS.template: Tweak according to changes in the
2572 distribution. Add back the dependencies of *.o files.
2574 * configh.dos.template: Synchronize with config.h.in.
2576 2002-05-09 Paul D. Smith <psmith@gnu.org>
2578 * file.c (file_timestamp_now): Use K&R function declaration.
2580 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2581 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2582 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2583 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2584 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2585 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2586 nlist.n_name is a pointer rather than an array.
2588 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2589 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2590 * configure.in: Use it instead of the old version.
2592 * main.c (main): Prefer setvbuf() to setlinebuf().
2594 2002-05-08 Paul D. Smith <psmith@gnu.org>
2596 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2597 (loadavg_LDADD): Ditto.
2599 2002-04-29 Paul D. Smith <psmith@gnu.org>
2601 * expand.c (recursively_expand_for_file): Rename
2602 recursively_expand() to recursively_expand_for_file() and provide
2603 an extra argument, struct file. If the argument is provided, set
2604 the variable scope to that of the file before expanding.
2605 * variable.h (recursively_expand): Make this a macro that invokes
2606 recursively_expand_for_file() with a NULL file pointer.
2607 * variable.c (target_environment): Call the renamed function and
2608 provide the current file context.
2609 Fixes Debian bug #144306.
2611 2002-04-28 Paul D. Smith <psmith@gnu.org>
2613 Allow $(call ...) user-defined variables to be self-referencing
2614 without throwing an error. Allows implementation of transitive
2615 closures, among other possibly useful things.
2616 Requested by: Philip Guenther <guenther@sendmail.com>
2618 * variable.h (struct variable): Add a new field: exp_count, and
2619 new macros to hold its size and maximum value.
2620 (warn_undefined): Make this a macro.
2621 * variable.c (define_variable_in_set): Initialize it.
2622 * expand.c (recursively_expand): If we detect recursive expansion
2623 of a variable, check the exp_count field. If it's greater than 0
2624 allow the recursion and decrement the count.
2625 (warn_undefined): Remove this (now a macro in variable.h).
2626 * function.c (func_call): Before we expand the user-defined
2627 function, modify its exp_count field to contain the maximum
2628 number of recursive calls we'll allow. After the call, reset it
2631 2002-04-21 Paul D. Smith <psmith@gnu.org>
2633 Modified to use latest autoconf (2.53), automake (1.6.1), and
2634 gettext (0.11.1). We're using gettext's new "external" support,
2635 to avoid including libintl source with GNU make.
2637 * README.cvs: New file. Explain how to build GNU make from CVS.
2639 * configure.in: Modify checking for the system glob library.
2640 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2641 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2642 etc. will manage it correctly). Set an automake conditional
2643 USE_LOCAL_GLOB to decide whether to compile the glob library.
2645 * getloadavg.c (main): Include make.h in the "TEST" program to
2648 * Makefile.am: Remove special rules for loadavg. Replace them
2649 with Automake capabilities for building extra programs.
2651 * signame.c: This file does nothing if the system provide
2652 strsignal(). If not, it implements strsignal(). If the system
2653 doesn't define sys_siglist, then we make our own; otherwise we use
2655 * signame.h: Removed.
2657 * main.c (main): No need to invoke signame_init(). Update copyright.
2659 * ABOUT-NLS: Removed.
2660 * gettext.c: Removed.
2661 * gettext.h: Get a simplified copy from the gettext package.
2663 * i18n/*.po: Moved to po/.
2666 * config/*: Created. Contains package configuration helper files.
2667 * config.guess, config.sub: Moved to config directory.
2669 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2670 Rework to use new-style autoconf features. Use the "external"
2671 mode for gettext. Make the build.sh config file conditional on
2672 whether build.sh.in exists, to avoid autoconf errors.
2673 * acinclude.m4: Removed almost all macros as being obsolete.
2674 Rewrote remaining macros to use AC_DEFINE.
2675 * acconfig.h: Removed.
2677 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2678 conditional to handle customs support. Remove special handling
2681 2002-04-20 Paul D. Smith <psmith@gnu.org>
2683 * function.c (func_call): Don't mark the argument variables $1,
2684 etc. as recursive. They've already been fully expanded so
2685 there's no need to do it again, and doing so strips escaped $'s.
2686 Reported by Sebastian Glita <glseba@yahoo.com>.
2688 * remake.c (notice_finished_file): Walk through double-colon
2689 entries via the prev field, not the next field!
2690 Reported by Greg McGary <greg@mcgary.org>.
2692 * main.c (main): If the user specifies -q and asks for a specific
2693 target which is a makefile, we got an assert. In that case it
2694 turns out we should continue normally instead.
2696 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2698 * i18n/he.po: Installed a new translation.
2700 2002-01-07 Paul D. Smith <psmith@gnu.org>
2702 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2704 2001-12-04 Paul D. Smith <psmith@gnu.org>
2706 * i18n/ja.po: Installed an updated translation.
2708 2001-09-06 Paul Eggert <eggert@twinsun.com>
2710 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2711 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2713 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2715 (main): Get rid of any avoidable limit on stack size.
2717 2001-09-04 Paul D. Smith <psmith@gnu.org>
2719 * i18n/da.po: Installed an updated translation.
2721 2001-08-03 Paul D. Smith <psmith@gnu.org>
2723 * i18n/fr.po: Installed an updated translation.
2724 Resolves Debian bug #106720.
2726 2001-06-13 Paul D. Smith <psmith@gnu.org>
2728 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2731 2001-06-11 Paul D. Smith <psmith@gnu.org>
2733 * i18n/ko.po: Installed a new translation.
2735 2001-05-06 Paul D. Smith <psmith@gnu.org>
2737 Modify the EINTR handling.
2739 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2740 the way in which we manage the file descriptor/signal handler race
2741 trap to be more efficient.
2743 2001-05-06 Paul Eggert <eggert@twinsun.com>
2745 Restart almost all system calls that are interrupted, instead
2746 of worrying about EINTR. The lone exception is the read() for
2749 * configure.in (HAVE_SA_RESTART): New macro.
2750 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2751 * main.c (main): Use SA_RESTART instead of the old,
2752 nonstandard SA_INTERRUPT.
2754 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2755 * main.c (bsd_signal): New function or macro,
2756 if the implementation doesn't supply it.
2757 (The bsd_signal function will be in POSIX 1003.1-200x.)
2758 (HANDLESIG): Remove.
2759 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2761 * make.h (EINTR_SET): Remove.
2762 (SA_RESTART): New macro.
2764 * arscan.c (ar_member_touch): Don't worry about EINTR.
2765 * function.c (func_shell): Likewise.
2766 * job.c (reap_children, free_child, new_job): Likewise.
2767 * main.c (main): Likewise.
2768 * remake.c (touch_file, name_mtime): Likewise.
2770 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2771 if fstat failed with errno!=EINTR, the error was ignored.
2773 * job.c (set_child_handler_action_flags): New function.
2774 (new_job): Use it to temporarily clear the SIGCHLD action flags
2775 while reading the token.
2777 2001-05-02 Paul D. Smith <psmith@gnu.org>
2779 * job.c (start_job_command): Don't add define/endef per-line flags
2780 to the top-level flags setting.
2782 2001-04-03 Paul D. Smith <psmith@gnu.org>
2784 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2785 bit on error, so check for odd return values, not non-0 return
2787 (VMS_get_member_info): Calculate the timezone differences correctly.
2788 Reported by John Fowler <jfowler@nyx.net>.
2791 2001-03-14 Paul D. Smith <psmith@gnu.org>
2793 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2794 value before invoking define_variable().
2795 Reported by John Fowler <jfowler@nyx.net>.
2797 2001-02-07 Paul D. Smith <psmith@gnu.org>
2799 * read.c (record_target_var): If we reset the variable due to a
2800 command-line variable setting overriding it, turn off the "append"
2803 2001-01-17 Paul D. Smith <psmith@gnu.org>
2805 * variable.c (lookup_variable) [VMS]: When getting values from the
2806 environment, allocate enough space for the _value_ plus escapes,
2807 not enough space for the name plus escapes :-/.
2808 Reported by John Fowler <jfowler@nyx.net>.
2810 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2811 warnings that make generates, so it doesn't look like an error.
2812 Reported by Karl Berry <karl@gnu.org>.
2815 Fix for PR/2020: Rework appended target-specific variables. I'm
2816 fairly confident this algorithm is finally correct.
2818 * expand.c (allocated_variable_append): Rewrite. Instead of
2819 expanding each appended variable then adding all the expanded
2820 strings together, we append all the unexpanded values going up
2821 through the variable set contexts, then expand the final result.
2822 This behaves just like non-target-specific appended variable
2823 values, while the old way didn't in various corner cases.
2824 (variable_append): New function: recursively append the unexpanded
2825 value of a variable, walking from the outermost variable scope to
2827 * variable.c (lookup_variable): Remove the code that looked up the
2828 variable set list if the found variable was "append". We don't
2830 (lookup_variable_in_set): Make this non-static so we can use it
2832 (try_variable_definition): Use lookup_variable_in_set() rather
2833 than faking out current_variable_set_list by hand (cleanup).
2834 * variable.h: Add a prototype for the now non-static
2835 lookup_variable_in_set().
2837 2000-11-17 Paul D. Smith <psmith@gnu.org>
2839 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2840 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2841 before throwing a fit.
2843 2000-11-17 Paul D. Smith <psmith@gnu.org>
2845 * read.c (readline): CRLF calculations had a hole, if you hit the
2846 buffer grow scenario just right. Reworked the algorithm to avoid
2847 the need for len or lastlen at all. Problem description with
2848 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2850 2000-10-24 Paul D. Smith <psmith@gnu.org>
2852 * gettext.c (SWAP): Declare this with the prototype, otherwise
2853 some systems don't work (non-32-bit? Reported for Cray T3E).
2854 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2856 2000-10-05 Paul D. Smith <psmith@gnu.org>
2858 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2859 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2861 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2863 2000-09-22 Paul D. Smith <psmith@gnu.org>
2865 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2866 parts of the real gettext.h here, and we expect to really include
2867 the real gettext.h later. If we keep this #define, it's ignored.
2869 2000-09-21 Paul D. Smith <psmith@gnu.org>
2871 * main.c (log_working_directory): Rework the text to use complete
2872 sentences, to make life simpler for the translators.
2874 2000-08-29 Paul D. Smith <psmith@gnu.org>
2876 * file.c (remove_intermediates): Print a debug message before we
2877 remove intermediate files, so the user (if she uses -d) knows
2880 2000-08-21 Paul D. Smith <psmith@gnu.org>
2882 * variable.c (try_variable_definition): Change how we handle
2883 target-specific append variable defns: instead of just setting the
2884 value, expand it as an append _but_ only within the current
2885 target's context. Otherwise we lose all but the last value if the
2886 variable is appended more than once within the current target
2887 context. Fixes PR/1831.
2889 2000-08-16 Paul D. Smith <psmith@gnu.org>
2891 * function.c (func_shell): Nul-terminate the buffer before
2892 printing an exec error message (just in case it's not!).
2893 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2895 2000-07-25 Paul D. Smith <psmith@gnu.org>
2897 * job.c (construct_command_argv_internal): Add "~" to the list of
2898 sh_chars[] which disallow optimizing out the shell call.
2900 2000-07-23 Paul Eggert <eggert@twinsun.com>
2902 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2903 supersedes --disable-nsec-timestamps.
2904 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2905 * README: Remove --disable-nsec-timestamps.
2907 * filedef.h (struct file.low_resolution_time): New member.
2908 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2909 * remake.c (update_file_1):
2910 Avoid spurious rebuilds due to low resolution time stamps,
2911 generalizing the earlier code that applied only to archive members.
2912 (f_mtime): Archive members always have low resolution time stamps.
2914 * configure.in: Remove --disable-nsec-timestamps, as this has
2915 been superseded by .LOW_RESOLUTION_TIME.
2917 2000-07-23 Paul Eggert <eggert@twinsun.com>
2919 * configure.in (enable_nsec_timestamps): Renamed from
2920 make_cv_nsec_timestamps, since enable/disable options
2921 shouldn't be cached.
2923 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2924 and Paul Eggert <eggert@twinsun.com>
2926 * file.c (file_timestamp_now):
2927 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2928 so that clock_gettime is not linked unless needed.
2930 * filedef.h (FILE_TIMESTAMP_HI_RES):
2931 Remove definition; "configure" now does this.
2933 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2934 to before high resolution file timestamp check,
2935 since that check now uses uintmax_t.
2936 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2937 high resolution file timestamps.
2938 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2939 so that we don't link in clock_gettime unnecessarily.
2941 2000-07-17 Paul D. Smith <psmith@gnu.org>
2943 * i18n/ja.po: New version of the translation file.
2945 2000-07-07 Paul D. Smith <psmith@gnu.org>
2947 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2948 the offset calculation.
2949 (name_mtime): Replace EINTR test with EINTR_SET macro.
2951 2000-07-07 Paul Eggert <eggert@twinsun.com>
2955 * remake.c (update_file_1):
2956 Avoid spurious rebuilds of archive members due to their
2957 timestamp resolution being only one second.
2958 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2959 the clock's resolution being lower than file timestamps'.
2960 When warning about future timestamps, report only the discrepancy,
2961 not the absolute value of the timestamp and the current time.
2963 * file.c (file_timestamp_now): New arg RESOLUTION.
2964 * filedef.h (file_timestamp_now): Likewise.
2965 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2967 2000-07-05 Paul D. Smith <psmith@gnu.org>
2969 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2970 to listp. Fixes PR/1793.
2972 2000-06-26 Paul Eggert <eggert@twinsun.com>
2974 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2976 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2978 * remake.c (f_mtime): Remove unused var memtime.
2980 2000-06-25 Martin Buchholz <martin@xemacs.org>
2982 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2983 Ran spell-check on make.texinfo.
2985 2000-06-23 Paul D. Smith <psmith@gnu.org>
2987 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2988 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2989 * make.h: Define these macros.
2991 * Version 3.79.1 released.
2993 * configure.in: Add a new option, --disable-nsec-timestamps, to
2994 avoid using sub-second timestamps on systems that support it. It
2995 can lead to problems, e.g. if your makefile relies on "cp -p".
2996 * README.template: Document the issue with "cp -p".
2998 * config.guess, config.sub: Updated.
