14 2007-10-12 Eli Zaretskii <eliz@gnu.org>
16 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
17 a more complex value than a simple shell: if it's not a default
18 shell now then expand it and see if is a default shell then.
20 2007-10-10 Eli Zaretskii <eliz@gnu.org>
22 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from

44 2007-09-11 Paul Smith <psmith@gnu.org>
46 * doc/make.texi (Special Variables): Moved this into the "How to
47 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
48 (MAKEFILE_LIST) No longer a section; this was added into the
49 "Special Variables" section.

62 were chopping the last char.
64 * NEWS: Announce the .RECIPEPREFIX special variable.

74 scripts here, so they're not stored in the commands array at all,
75 rather than waiting and stripping them out during command construction.
76 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
78 2007-08-15 Paul Smith <psmith@gnu.org>
80 * doc/make.texi (GNU Free Documentation License): The fdl.texi

123 "Expansion of a deferred"
124 Fixes Savannah bug #20018.
126 * expand.c (variable_expand_for_file): Preserve the value of
127 reading_file rather than setting it to 0 at the end.

144 Dave Korn <dave.korn@artimi.com>
146 2007-05-08 Paul Smith <psmith@gnu.org>
148 Fix Savannah bug #19656:
150 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
152 * make.h: Change all case-insensitive string compares to use
153 strcasecmp() (from POSIX). If we don't have that but do have one
154 of the others, define strcasecmp to be one of those instead. If
155 we don't have any, declare a prototype for our own version.
157 * misc.c (strcasecmp): Use this if we can't find any native
158 case-insensitive string comparison function.
159 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
160 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
162 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
163 strcasecmp() instead of stricmp().
164 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
165 instead of strcmpi().
166 * acinclude.m4: Remove the strcasecmp() check from here.
168 2007-03-21 Paul Smith <psmith@gnu.org>
170 * configure.in: Don't turn on case-insensitive file system support
171 if --disable-... is given. Fixes Savannah bug #19348.
173 2007-03-19 Paul Smith <psmith@gnu.org>
175 * ALL: Use the strcache for all file name strings, or other
176 strings which we will never free. The goal is to save memory by
177 avoiding duplicate copies of strings. However, at the moment this
178 doesn't save much memory in most situations: due to secondary
179 expansion we actually save prerequisite lists twice (once before
180 the secondary expansion, and then again after it's been parsed
181 into individual file names in the dep list). We will resolve this
182 in a future change, by doing the parsing up-front for targets
183 where secondary expansion is not set.
185 Moving things into the strcache also allows us to use const
186 pointers in many more places.
188 2007-01-03 Paul Smith <psmith@gnu.org>
190 * make.h (ENULLLOOP): Reset errno after each failed invocation of
191 the function, not just the first. Fixes Savannah bug #18680.
193 2006-11-18 Paul Smith <psmith@gnu.org>
195 * strcache.c (strcache_add_len): Don't allocate a new buffer
196 unless the string is not already nil-terminated. Technically this
197 is a violation of the standard, since we may be passed an array
198 that is not long enough to test one past. However, in make this
199 is never true since we only use nil-terminated strings or
202 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
204 * main.c: New global cmd_prefix, defaults to '\t'.
205 * job.c (construct_command_argv_internal): Use cmd_prefix instead
209 (dir_contents_file_exists_p): Check for an error return from
210 readdir(), just in case.
212 * commands.c: Constified.
213 * default.c: Constified.
214 * expand.c: Constified.
215 * function.c: Partial constification.
216 * variable.c: Partial constification.
217 * vmsify.c: Constification. Hard to test this but I hope I didn't

222 2006-11-16 Eli Zaretskii <eliz@gnu.org>
224 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
225 backslashes and drive letters as absolute.
227 2006-10-22 Paul Smith <psmith@gnu.org>
229 * main.c (struct command_switch): Use const and void*.
231 2006-10-21 Paul Smith <psmith@gnu.org>
234 * arscan.c: Constified.
236 2006-09-30 Paul Smith <psmith@gnu.org>
238 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
239 point to lastword since the example was updated.
240 Fixes Savannah bug #16304.
241 (Secondary Expansion): Correct example description.
242 Fixes Savannah bug #16468.
243 (Makefile Contents): Clarify that comments cannot appear within
244 variable references or function calls.
245 Fixes Savannah bug #16577.
246 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
247 Fixes Savannah bug #17701.
248 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

292 * README.cvs: Add a reminder to notify the GNU translation robot.
294 * doc/make.texi: Change @direcategory (requested by Karl Berry).
296 2006-04-20 Paul D. Smith <psmith@gnu.org>
298 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
299 that don't have extended grep.
300 (cvsclean): Use $(PERL) instead of perl.
302 2006-04-09 Paul D. Smith <psmith@gnu.org>
304 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
306 * expand.c, implicit.c, main.c, read.c: Rename variables so that
307 inner-scope variables don't mask outer-scope variables.
309 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

368 Declare and define sh_chars_sh[].
370 2006-03-23 Paul D. Smith <psmith@gnu.org>
372 * configure.in: Look for build.sh.in in $srcdir so it will be
373 built for remote configurations as well.

376 Fixes Savannah bug #16166.
378 * misc.c (log_access): Takes a const char *.
379 * function.c (fold_newlines): Takes an unsigned int *.

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

459 * commands.c (set_file_variables): Realloc, not malloc, the static
460 string values to avoid memory leaks.
462 * expand.c (recursively_expand_for_file): Only set reading_file to
463 an initialized value.
465 * implicit.c (pattern_search): We need to make a copy of the stem
466 if we get it from an intermediate dep, since those get freed.

477 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
478 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
479 the calls to _beginthreadex.
481 * expand.c (recursively_expand_for_file): Initialize `save' to
482 prevent compiler warnings.

501 Fix for Savannah bug #106.
503 * expand.c (expanding_var): Keep track of which variable we're
504 expanding. If no variable is being expanded, it's the same as
506 * make.h (expanding_var): Declare it.
507 * expand.c (recursively_expand_for_file): Set expanding_var to the
508 current variable we're expanding, unless there's no file info in
509 it (could happen if it comes from the command line or a default
510 variable). Restore it before we exit.

526 an impossible file, free it.

535 archive support is enabled.

550 A new internal capability: the string cache is a read-only cache
551 of strings, with a hash table interface for fast lookup. Nothing
552 in the cache will ever be freed, so there's no need for reference
553 counting, etc. This is the beginning of a full solution for
554 Savannah bug #15182, but for now we only store makefile names here.
556 * strcache.c: New file. Implement a read-only string cache.
557 * make.h: Add prototypes for new functions.

566 directory time stamp didn't change, except on FAT filesystems.
567 Suggested by J. David Bryan <jdbryan@acm.org>.
569 2006-02-09 Paul D. Smith <psmith@gnu.org>
571 * function.c (func_or): Implement a short-circuiting OR function.
572 (func_and): Implement a short-circuiting AND function.
573 (function_table_init): Update the table with the new functions.
574 * doc/make.texi (Conditional Functions): Changed the "if" section
575 to one on general conditional functions. Added documentation for
576 $(and ...) and $(or ...) functions.
577 * NEWS: Note new $(and ...) and $(or ...) functions.
579 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
581 * job.h (struct child): Add the dontcare bitfield.
582 * job.c (new_job): Cache dontcare flag.
583 * job.c (reap_children): Use cached dontcare flag instead of the
584 one in struct file. Fixes Savannah bug #15641.
586 2006-02-06 Paul D. Smith <psmith@gnu.org>
588 * vpath.c (selective_vpath_search): If the file we find has a
589 timestamp from -o or -W, use that instead of the real time.
590 * remake.c (f_mtime): If the mtime is a special token from -o or
591 -W, don't overwrite it with the real mtime.
592 Fixes Savannah bug #15341.
594 Updates from Markus Mauhart <qwe123@chello.at>:
596 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

598 invalid handle values.
599 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
600 manage invalid handles; remove them.

605 2006-02-05 Paul D. Smith <psmith@gnu.org>
607 * file.c (enter_file): Keep track of the last double_colon entry,
608 to avoid walking the list every time we want to add a new one.
609 Fixes Savannah bug #15533.
610 * filedef.h (struct file): Add a new LAST pointer.
612 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
613 the comparison. For 64-bits systems the result of the subtraction
614 might not fit into an int. Use comparison instead.
615 Fixes Savannah bug #15534.
617 * doc/make.texi: Update the chapter on writing commands to reflect
618 the changes made in 3.81 for backslash/newline and SHELL handling.

636 * prepare_w32.bat: Remove this file from the distribution.
638 2006-01-21 Eli Zaretskii <eliz@gnu.org>
640 * remake.c (update_goal_chain): Set g->changed instead of
641 incrementing it, as it is only 8-bit wide, and could overflow if
642 many commands got started in update_file.
644 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
646 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
647 MAXIMUM_WAIT_OBJECTS.

652 available number of slots.
653 (process_easy): Don't start new processes if all slots are used up.
655 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
656 are already more children than sub_proc.c can handle, behave as if
657 the load were too high.
658 (start_job_command): Fix a typo in error message when process_easy
661 2006-01-14 Eli Zaretskii <eliz@gnu.org>
663 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
664 the shell is not sh.exe.
666 * job.c (create_batch_file): Renamed from create_batch_filename;
667 all callers changed. Don't close the temporary file; return its
668 file descriptor instead. New arg FD allows to return the file
670 (construct_command_argv_internal): Use _fdopen instead of fopen to
673 2006-01-04 Paul D. Smith <psmith@gnu.org>
675 * readme.vms: Updates for case-insensitive VMS file systems from
676 Hartmut Becker <Hartmut.Becker@hp.com>.

687 * remake.c (update_file_1): Mark a prerequisite changed if it
690 * read.c (eval): Be sure to strip off trailing whitespace from the
691 prerequisites list properly. Also, initialize all fields in
692 struct dep when creating a new one.
694 2005-12-28 Paul D. Smith <psmith@gnu.org>
696 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
697 disable warnings for MSC.
698 Patch by Rob Tulloh <rtulloh@yahoo.com>.
700 2005-12-17 Eli Zaretskii <eliz@gnu.org>
702 * doc/make.texi (Execution): Add a footnote about changes in
703 handling of backslash-newline sequences. Mention the differences
704 on MS-DOS and MS-Windows.
706 * NEWS: More details about building the MinGW port and a pointer
707 to README.W32. Fix the section name that describes the new
708 backward-incompatible processing of backslash-newline sequences.
709 The special processing of SHELL set to "cmd" is only relevant to
710 MS-Windows, not MS-DOS.
712 2005-12-17 Eli Zaretskii <eliz@gnu.org>
714 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
715 to DWORD, to avoid compiler warnings.
716 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
717 use %ld in format, to avoid compiler warnings.

733 garbage happened to be on the heap.
735 2005-12-12 Paul D. Smith <psmith@gnu.org>
737 * make.1: Fix some display errors and document all existing options.
738 Patch provided by Mike Frysinger <vapier@gentoo.org>.
740 2005-12-11 Paul D. Smith <psmith@gnu.org>
742 * implicit.c (pattern_search): If 2nd expansion is not set for
743 this implicit rule, replace the pattern with the stem directly,
744 and don't re-expand the variable list. Along with the other
745 .SECONDEXPANSION changes below, fixes bug #13781.
747 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
749 * implicit.c (pattern_search): Mark other files that this rule
750 builds as targets so that they are not treated as intermediates
751 by the pattern rule search algorithm. Fixes bug #13022.
753 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
755 * remake.c (notice_finished_file): Propagate the change of
756 modification time to all the double-colon entries only if

773 2005-10-26 Paul Smith <psmith@gnu.org>
775 * read.c (record_files): Don't set deps flags if there are no deps.
776 * maintMakefile: We only need to build the templates when we are
777 creating a distribution, so don't do it for "all".
779 2005-10-24 Paul D. Smith <psmith@gnu.org>
781 Make secondary expansion optional: its enabled by declaring the
782 special target .SECONDEXPANSION.
784 * NEWS: Update information on second expansion capabilities.
785 * doc/make.texi (Secondary Expansion): Document the
786 .SECONDEXPANSION special target and its behavior.
787 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
788 prerequisite list was found in a static pattern rule.
789 (free_dep_chain): Declare a prototype.
790 * file.c (parse_prereqs): New function: break out some complexity
792 (expand_deps): If we aren't doing second expansion, replace % with
793 the stem for static pattern rules. Call the new function.
794 * filedef.h (parse_prereqs): Declare a prototype.
795 * implicit.c (pattern_search): Initialize the new staticpattern
797 * main.c (second_expansion): Declare a global variable to remember
798 if the special target has been seen. Initialize the new

801 * misc.c (free_dep_chain): New function: frees a struct dep list.
802 * read.c (read_all_makefiles): Initialize the staticpattern field.
803 (eval_makefile): Ditto.
804 (record_files): Check for the .SECONDEXPANSION target and set
805 second_expansion global if it's found.
806 Use the new free_dep_chain() instead of doing it by hand.
807 Set the staticpattern field for prereqs of static pattern targets.
809 2005-10-16 Paul D. Smith <psmith@gnu.org>
811 * main.c (main): Set CURDIR to be a file variable instead of a
812 default, so that values of CURDIR inherited from the environment
813 won't override the make value.
815 2005-09-26 Paul D. Smith <psmith@gnu.org>
817 * job.c (construct_command_argv_internal): If the line is empty
818 remember to free the temporary argv strings.
821 2005-09-16 Paul D. Smith <psmith@gnu.org>
823 * job.c (start_job_command): The noerror flag is a boolean (single
824 bit); set it appropriately.
825 Reported by Mark Eichin <eichin@metacarta.com>
827 2005-08-29 Paul D. Smith <psmith@gnu.org>
829 * function.c (func_error): On Windows, output from $(info ...)
830 seems to come in the wrong order. Try to force it with fflush().
832 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
834 * read.c (record_files): Move code that sets stem for static
835 pattern rules out of the if (!two_colon) condition so it is
836 also executed for two-colon rules. Fixes Savannah bug #13881.
838 2005-08-08 Paul D. Smith <psmith@gnu.org>
840 * make.h: Don't test that __STDC__ is non-0. Some compilers
841 (Windows for example) set it to 0 to denote "ISO C + extensions".
844 2005-08-07 Paul D. Smith <psmith@gnu.org>
846 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
847 conditional (slightly different version of a fix from Eli).
849 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
850 If make is running in parallel without -k and two jobs die in a
851 row, but not too close to each other, then make will quit without
852 waiting for the rest of the jobs to die.
854 * main.c (die): Don't reset err before calling reap_children() the
855 second time: we still want it to be in the error condition.
856 * job.c (reap_children): Use a static variable, rather than err,
857 to control whether or not the error message should be printed.
859 2005-08-06 Eli Zaretskii <eliz@gnu.org>
861 * w32/subproc/sub_proc.c: Include signal.h.
862 (process_pipe_io, process_file_io): Pass a pointer to a local
863 DWORD variable to GetExitCodeProcess. If the exit code is
864 CONTROL_C_EXIT, put SIGINT into pproc->signal.
866 * job.c [WINDOWS32]: Include windows.h.
867 (main_thread) [WINDOWS32]: New global variable.
868 (reap_children) [WINDOWS32]: Get the handle for the main thread
869 and store it in main_thread.
871 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
872 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
873 doing anything else. When we are done, close the main thread
874 handle and exit with status 130.
876 2005-07-30 Eli Zaretskii <eliz@gnu.org>
878 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
881 * main.c (find_and_set_default_shell): If found a DOSish shell,
882 set sh_found and the value of default_shell, and report the
883 findings in debug mode.
885 * job.c (construct_command_argv_internal): Check unixy_shell, not
886 no_default_sh_exe, to decide whether to use Unixy or DOSish
889 * README.W32: Update with info about the MinGW build.
891 * build_w32.bat: Support MinGW.
893 * w32/subproc/build.bat: Likewise.
895 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
898 * function.c (windows32_openpipe): Fix format strings for printing
901 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
903 (start_job_command): Fix format string for printing the result of
905 (start_job_command) [WINDOWS32]: Do not define.
906 (exec_command): Fix format string for printing HANDLE args.
908 * main.c (handle_runtime_exceptions): Fix sprintf format strings
909 to avoid compiler warnings.
910 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
911 (Note: some of these fixes were submitted independently by J. Grant)
913 2005-07-30 J. Grant <jg@jguk.org>
915 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
916 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
917 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
919 2005-07-15 Paul Smith <psmith@gnu.org>
921 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
922 we don't have a POSIX shell, then revert to the old
923 backslash-newline behavior (where they are stripped).
926 2005-07-08 Paul D. Smith <psmith@gnu.org>
928 * config.h.W32.template: Reorder to match the standard config.h,
929 for easier comparisons.
930 From J. Grant <jg@jguk.org>
932 * maintMakefile: Remove .dep_segment before overwriting it, in
933 case it's not writable or noclobber is set.
934 * expand.c (variable_expand_string): Cast result of pointer
935 arithmetic to avoid a warning.
936 * main.c (switches): Add full-fledged final initializer.
938 2005-07-06 Paul D. Smith <psmith@gnu.org>
940 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
941 * signame.c (strsignal): If we found _sys_siglist[] or
942 __sys_siglist[] use those instead of sys_siglist[].
943 From Albert Chin <china@thewrittenword.com>
945 2005-07-04 Paul D. Smith <psmith@gnu.org>
947 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
948 globfree(); set up to use the GNU versions.
949 From Martin Zinser <zinser@zinser.no-ip.info>
951 2005-07-03 Paul D. Smith <psmith@gnu.org>
953 From J. Grant <jg@jguk.org>:
955 * README.W32.template: Update the Windows and tested MSVC versions.
956 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
957 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
958 * build_w32.bat: Ditto.
959 * w32/subproc/build.bat: Ditto.
961 2005-06-28 Paul D. Smith <psmith@gnu.org>
963 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
964 declaration was checked but not present.
966 2005-06-27 Paul D. Smith <psmith@gnu.org>
968 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
969 to unsigned long. Fixes Savannah bug #13550.
971 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
972 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
973 Fixes Savannah bug #13551.
975 2005-06-26 Paul D. Smith <psmith@gnu.org>
977 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
978 it if ANSI_STRING is not set.
980 2005-06-25 Paul D. Smith <psmith@gnu.org>
982 * read.c (eval): If no filenames are passed to any of the
983 "include" variants, don't print an error.
984 * doc/make.texi (Include): Document this.
985 Fixes Savannah bug #1761.
987 * job.c (construct_command_argv_internal): Sanitize handling of
988 backslash/newline pairs according to POSIX: that is, keep the
989 backslash-newline in the command script, but remove a following
990 TAB character, if present. In the fast path, make sure that the
991 behavior matches what the shell would do both inside and outside
992 of quotes. In the slow path, quote the backslash and put a
993 literal newline in the string.
994 Fixes Savannah bug #1332.
995 * doc/make.texi (Execution): Document the new behavior and give
997 * NEWS: Make a note of the new behavior.
999 * make.h [WINDOWS32]: #include <direct.h>.
1000 Fixes Savannah bug #13478.
1002 * remake.c (name_mtime): If the stat() of a file fails and the -L
1003 option was given and the file is a symlink, take the best mtime of
1004 the symlink we can get as the mtime of the file and don't fail.
1005 Fixes Savannah bug #13280.
1007 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1008 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1009 inside a variable reference. Make this function static as it's
1011 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1012 parsing an unexpanded line looking for semicolons.
1013 Fixes Savannah bug #1454.
1014 * misc.c (remove_comments): Move this to read.c and make it static
1015 as it's only used there. Call find_char_unquote() with new arg.
1016 * make.h: Remove prototypes for find_char_unquote() and
1017 remove_comments() since they're static now.
1019 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1020 its export flag and obtain its value. When we need to re-exec,
1021 increment the value and add it into the environment.
1022 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1023 * NEWS: Mention MAKE_RESTARTS.
1024 * main.c (always_make_set): New variable. Change the -B option to
1025 set this one instead.
1026 (main): When checking makefiles, only set always_make_flag if
1027 always_make_set is set AND the restarts flag is 0. When building
1028 normal targets, set it IFF always_make_set is set.
1029 (main): Avoid infinite recursion with -W, too: only set what-if
1030 files to NEW before we check makefiles if we've never restarted
1031 before. If we have restarted, set what-if files to NEW _after_ we
1033 Fixes Savannah bug #7566:
1035 2005-06-17 Paul D. Smith <psmith@gnu.org>
1037 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1038 in the prerequisites list.
1040 2005-06-12 Paul D. Smith <psmith@gnu.org>
1042 Fix Savannah bug # 1328.
1044 * configure.in: Check for atexit().
1045 * misc.c (close_stdout): Test stdout to see if writes to it have
1046 failed. If so, be sure to exit with a non-0 error code. Based on
1047 code found in gnulib.
1048 * make.h: Prototype.
1049 * main.c (main): Install close_stdout() with atexit().
1051 2005-06-10 Paul D. Smith <psmith@gnu.org>
1053 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1055 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1056 headers; make vmsWaitForChildren() static; extern vmsify().
1057 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1058 Don't create child_execute_job() here (it's in vmsjobs.c).
1059 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1061 2005-06-09 Paul D. Smith <psmith@gnu.org>
1063 * variable.c (push_new_variable_scope): File variables point
1064 directly to the global_setlist variable. So, inserting a new
1065 scope in front of that has no effect on those variables: they
1066 don't go through current_variable_set_list. If we're pushing a
1067 scope and the current scope is global, push it "the other way" so
1068 that the new setlist is in the global_setlist variable, and
1069 next points to a new setlist with the global variable set.
1070 (pop_variable_scope): Properly undo a push with the new
1072 Fixes Savannah bug #11913.
1074 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1076 * job.c (reap_children): Don't die of the command failed but
1077 the dontcare flag is set. Fixes Savannah bug #13216.
1079 * implicit.c (pattern_search): When creating a target from
1080 an implicit rule match, lookup pattern target and set precious
1081 flag in a newly created target. Fixes Savannah bug #13218.
1083 2005-05-13 Paul D. Smith <psmith@gnu.org>
1085 Implement "if... else if... endif" syntax.
1087 * read.c (eval): Push all checks for conditional words ("ifeq",
1088 "else", etc.) down into the conditional_line() function.
1089 (conditional_line): Rework to allow "else if..." clause. New
1090 return value -2 for lines which are not conditionals. The
1091 ignoring flag can now also be 2, which means "already parsed a
1092 true branch". If that value is seen no other branch of this
1093 conditional can be considered true. In the else parsing if there
1094 is extra text after the else, invoke conditional_line()
1095 recursively to see if it's another conditional. If not, it's an
1096 error. If so, raise the conditional value to this level instead
1097 of creating a new conditional nesting level. Special check for
1098 "else" and "endif", which aren't allowed on the "else" line.
1099 * doc/make.texi (Conditional Syntax): Document the new syntax.
1101 2005-05-09 Paul D. Smith <psmith@gnu.org>
1103 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1104 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1105 recurses to the w32 directory, even on non-Windows systems. Use
1106 the method suggested in the automake manual.
1107 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1108 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1110 2005-05-07 Paul D. Smith <psmith@gnu.org>
1112 * main.c (die): If we're dying with a fatal error (not that a
1113 command has failed), write back any leftover tokens before we go.
1115 * job.c (set_child_handler_action_flags): If there are jobs
1116 waiting for the load to go down, set an alarm to go off in 1
1117 second. This allows us to wake up from a potentially long-lasting
1118 read() and start a new job if the load has gone down. Turn it off
1120 (job_noop): Dummy signal handler function.
1121 (new_job): Invoke it with the new semantics.
1123 * docs/make.texi: Document secondary expansion. Various cleanups
1126 2005-05-03 Paul D. Smith <psmith@gnu.org>
1128 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1129 the targets which are to ultimately be made are called "goals";
1130 see the GNU make manual. Also, MAKECMDGOALS, etc.
1132 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1133 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1134 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1136 2005-05-02 Paul D. Smith <psmith@gnu.org>
1138 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1139 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1140 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1141 functions to vmsjobs.c. #include it into jobs.c.
1143 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1144 jobserver tokens. I found that this happens when an exported
1145 recursive variable contains a $(shell ...) function reference: in
1146 this situation we could "forget" to write back a token.
1148 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1149 we have. It's not reliable to depend on the number of children in
1150 our linked list so keep a separate count.
1151 (new_job): Check jobserver_tokens rather than children &&
1152 waiting_jobs. Increment jobserver_tokens when we get one.
1153 (free_child): If jobserver_tokens is 0, internal error. If it's
1154 >1, write a token back to the jobserver pipe (we don't write a
1155 token for the "free" job). Decrement jobserver_tokens.
1157 * main.c: Add variable master_job_slots.
1158 (main): Set it to hold the number of jobs requested if we're the
1159 master process, when using the jobserver.
1160 (die): Sanity checks: first test jobserver_tokens to make sure
1161 this process isn't holding any tokens we didn't write back.
1162 Second, if master_job_slots is set count the tokens left in the
1163 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1165 2005-04-24 Paul D. Smith <psmith@gnu.org>
1167 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1168 with -l# can lose jobserver tokens, because waiting jobs are not
1169 consulted properly when checking for the "free" token.
1171 * job.c (free_child): Count waiting_jobs as having tokens.
1172 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1173 handle jobs waiting for the load to drop.
1175 2005-04-23 Paul D. Smith <psmith@gnu.org>
1177 * main.c (main): Be careful to not core if a variable setting in
1178 the environment doesn't contain an '='. This is illegal but can
1179 happen in broken setups.
1180 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1182 2005-04-12 Paul D. Smith <psmith@gnu.org>
1184 The second expansion feature causes significant slowdown. Timing
1185 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1186 read the makefile before the feature, to 11+s to do the same
1187 operations after the feature. Additionally, memory usage
1188 increased drastically. To fix this I added some intelligence that
1189 avoids the overhead of the second expansion unless it's required.
1191 * dep.h: Add a new boolean field, need_2nd_expansion.
1193 * read.c (eval): When creating the struct dep for the target,
1194 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1195 (record_files): If there's a "%" in a static pattern rule, it gets
1196 converted to "$*" so set need_2nd_expansion to 1.
1198 * file.c (expand_deps): Rework to be more efficient. Only perform
1199 initialize_file_variables(), set_file_variables(), and
1200 variable_expand_for_file() if the need_2nd_expansion is set.
1202 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1203 (pattern_search): Ditto.
1204 * main.c (handle_non_switch_argument): Ditto.
1206 * read.c (read_all_makefiles): Ditto.
1207 (eval_makefile): Ditto.
1209 2005-04-07 Paul D. Smith <psmith@gnu.org>
1211 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1212 * variable.c (sync_Path_environment): Ditto.
1213 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1215 * main.c (main): Define the .FEATURES variable.
1216 * NEWS: Announce .FEATURES.
1217 * doc/make.texi (Special Variables): Document .FEATURES.
1219 * remake.c (check_dep): If a file is .PHONY, update it even if
1220 it's marked intermediate. Fixes Savannah bug #12331.
1222 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1224 * file.c (expand_deps): Factor out the second expansion and
1225 prerequisite line parsing logic from snap_deps().
1227 * file.c (snap_deps): Use expand_deps(). Expand and parse
1228 prerequisites of the .SUFFIXES special target first. Fixes
1229 Savannah bug #12320.
1231 2005-03-13 Paul D. Smith <psmith@gnu.org>
1233 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1236 2005-03-11 Paul D. Smith <psmith@gnu.org>
1238 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1239 available, not undefined (from Earnie Boyd).
1241 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1243 * implicit.c (pattern_search): Mark an intermediate target as
1244 precious if it happened to be a prerequisite of some (other)
1245 target. Fixes Savannah bug #12267.
1247 2005-03-09 Paul D. Smith <psmith@gnu.org>
1249 * read.c (eval_makefile): Add alloca(0).
1250 (eval_buffer): Ditto.
1252 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1254 * main.c (main): Use o_file instead of o_default when defining
1255 the .DEFAULT_TARGET special variable.
1256 * read.c (eval): Use define_variable_global() instead of
1257 define_variable() when setting new value for the .DEFAULT_TARGET
1258 special variable. Fixes Savannah bug #12266.
1260 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1262 * imlicit.c (pattern_search): Mark files for which an implicit
1263 rule has been found as targets. Fixes Savannah bug #12202.
1265 2005-03-04 Paul D. Smith <psmith@gnu.org>
1268 * doc/make.texi (Automatic Variables): Document $|.
1270 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1272 * read.c (record_files): Instead of substituting % with
1273 actual stem value in dependency list replace it with $*.
1274 This fixes stem triple expansion bug.
1276 * implicit.c (pattern_search): Copy stem to a separate
1277 buffer and make it a properly terminated string. Assign
1278 this buffer instead of STEM (which is not terminated) to
1279 f->stem. Instead of substituting % with actual stem value
1280 in dependency list replace it with $*. This fixes stem
1281 triple expansion bug.
1283 2005-03-01 Paul D. Smith <psmith@gnu.org>
1285 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1286 on Windows, as it takes a handle not a pid. Just exit.
1287 Fix from patch #3679, provided by Alessandro Vesely.
1289 * configure.in: Update check for sys_siglist[] from autoconf manual.
1290 * signame.c (strsignal): Update to use the new autoconf macro.
1292 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1294 * read.c (record_files): Add a check for the list of prerequisites
1295 of a static pattern rule being empty. Fixes Savannah bug #12180.
1297 2005-02-28 Paul D. Smith <psmith@gnu.org>
1299 * doc/make.texi (Text Functions): Update docs to allow the end
1300 ordinal for $(wordlist ...) to be 0.
1301 * function.c (func_wordlist): Fail if the start ordinal for
1302 $(wordlist ...) is <1. Matches documentation.
1303 Resolves Savannah support request #103195.
1305 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1306 previously we were stopping when !-q, exactly the opposite. This
1307 has been wrong since version 1.34, in 1994!
1308 (update_file): If we got an error don't break out to run more
1309 double-colon rules: just return immediately.
1310 Fixes Savannah bug #7144.
1312 2005-02-27 Paul D. Smith <psmith@gnu.org>
1314 * misc.c (end_of_token): Make argument const.
1315 * make.h: Update prototype.
1317 * function.c (abspath, func_realpath, func_abspath): Use
1318 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1319 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1320 * read.c (record_files): Ditto.
1321 * variable.c (do_variable_definition): Ditto.
1323 * function.c (func_error): Create a new function $(info ...) that
1324 simply prints the message to stdout with no extras.
1325 (function_table_init): Add new function to the table.
1326 * NEWS: Add $(info ...) reference.
1327 * doc/make.texi (Make Control Functions): Document it.
1329 New feature: if the system supports symbolic links, and the user
1330 provides the -L/--check-symlink-time flag, then use the latest
1331 mtime between the symlink(s) and the target file.
1333 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1334 readlink(). If both are available, define MAKE_SYMLINKS.
1335 * main.c: New variable: check_symlink_flag.
1336 (usage): Add a line for -L/--check-symlink-times to the help string.
1337 (switches): Add -L/--check-symlink-times command line argument.
1338 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1339 print a warning and disable it again.
1340 * make.h: Declare check_symlink_flag.
1341 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1342 if the file is a symlink then check each link in the chain and
1343 choose the NEWEST mtime we find as the mtime for the file. The
1344 newest mtime might be the file itself!
1345 * NEWS: Add information about this new feature.
1346 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1348 Avoid core dumps described in Savannah bug # 12124:
1350 * file.c: New variable snapped_deps remember whether we've run
1352 (snap_deps): Set it.
1353 * filedef.h: Extern it.
1354 * read.c (record_files): Check snapped_deps; if it's set then
1355 we're trying to eval a new target/prerequisite relationship from
1356 within a command script, which we don't support. Fatal.
1358 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1360 Implementation of the .DEFAULT_TARGET special variable.
1362 * read.c (eval): If necessary, update default_target_name when
1364 * read.c (record_files): Update default_target_file if
1365 default_target_name has changed.
1366 * main.c (default_target_name): Define.
1367 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1368 default_target_name is set use default_target_file as a root
1370 * filedef.h (default_target_name): Declare.
1371 * dep.h (free_dep_chain):
1372 * misc.c (free_dep_chain): Change to operate on struct nameseq
1373 and change name to free_ns_chain.
1374 * file.c (snap_deps): Update to use free_ns_chain.
1376 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1378 Implementation of the second expansion in explicit rules,
1379 static pattern rules and implicit rules.
1381 * read.c (eval): Refrain from chopping up rule's dependencies.
1382 Store them in a struct dep as a single dependency line. Remove
1383 the code that implements SySV-style automatic variables.
1385 * read.c (record_files): Adjust the code that handles static
1386 pattern rules to expand all percents instead of only the first
1387 one. Reverse the order in which dependencies are stored so that
1388 when the second expansion reverses them again they appear in
1389 the makefile order (with some exceptions, see comments in
1390 the code). Remove the code that implements SySV-style automatic
1393 * file.c (snap_deps): Implement the second expansion and chopping
1394 of dependency lines for explicit rules.
1396 * implicit.c (struct idep): Define an auxiliary data type to hold
1397 implicit rule's dependencies after stem substitution and
1400 * implicit.c (free_idep_chain): Implement.
1402 * implicit.c (get_next_word): Implement helper function for
1403 parsing implicit rule's dependency lines into words taking
1404 into account variable expansion requests. Used in the stem
1407 * implicit.c (pattern_search): Implement the second expansion
1408 for implicit rules. Also fixes bug #12091.
1410 * commands.h (set_file_variables): Declare.
1411 * commands.c (set_file_variables): Remove static specifier.
1413 * dep.h (free_dep_chain): Declare.
1414 * misc.c (free_dep_chain): Implement.
1416 * variable.h (variable_expand_for_file): Declare.
1417 * expand.c (variable_expand_for_file): Remove static specifier.
1419 * make.h (strip_whitespace): Declare.
1420 * function.c (strip_whitespace): Remove static specifier.
1422 2005-02-26 Paul D. Smith <psmith@gnu.org>
1424 * main.c (main): Check for ferror() when reading makefiles from stdin.
1425 Apparently some shells in Windows don't close pipes properly and
1428 2005-02-24 Jonathan Grant <jg@jguk.org>
1430 * configure.in: Add MinGW configuration options, and extra w32 code
1432 * Makefile.am: Add MinGW configuration options, and extra w32 code
1434 * main.c: Determine correct program string (after last \ without .exe).
1435 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1437 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1438 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1439 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1440 environment support.
1442 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1444 * function.c (func_shell): When initializing error_prefix, check
1445 that reading file name is not null. This fixes long-standing
1446 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1448 2005-02-09 Paul D. Smith <psmith@gnu.org>
1450 * maintMakefile: Update the CVS download URL to simplify them.
1451 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1452 downloading the .texi files from Savannah now.
1454 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1456 * main.c (handle_non_switch_argument): Only add variables to
1457 command_variables if they're not already there: duplicate settings
1458 waste space and can be confusing to read.
1460 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1461 this header is never included by non-WINDOWS32 code, and it
1462 requires <config.h> to define which isn't always included first.
1464 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1465 testing MINGW32 versions.
1467 * main.c (log_working_directory): flush stdout to be sure the WD
1468 change is printed before any stderr messages show up.
1470 2005-02-01 Paul D. Smith <psmith@gnu.org>
1472 * maintMakefile (po_repo): Update the GNU translation site URL.
1474 2004-12-01 Paul D. Smith <psmith@gnu.org>
1476 * main.c (main): Change char* env_shell to struct variable shell_var.
1477 * variable.c (target_environment): Use new shell_var.
1479 2004-11-30 Paul D. Smith <psmith@gnu.org>
1481 * configure.in: The old way we avoided creating build.sh from
1482 build.sh.in before build.sh.in exists doesn't work anymore; we
1483 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1484 the help!). This also keeps automake from complaining.
1485 * Makefile.am (README): Add a dummy target so automake won't
1486 complain that this file doesn't exist when we checkout from CVS.
1487 * maintMakefile (.dep_segment): Rewrite this rule since newer
1488 versions of automake don't provide DEP_FILES.
1490 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1492 Implementation of `realpath' and `abspath' built-in functions.
1494 * configure.in: Check for realpath.
1495 * function.c (abspath): Return an absolute file name that does
1496 not contain any `.' or `..' components, nor repeated `/'.
1497 * function.c (func_abspath): For each name call abspath.
1498 * function.c (func_realpath): For each name call realpath
1499 from libc or delegate to abspath if realpath is not available.
1500 * doc/make.texi (Functions for File Names): Document new functions.
1501 * doc/make.texi (Quick Reference): Ditto.
1503 2004-11-28 Paul D. Smith <psmith@gnu.org>
1505 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1506 arguments. Fixes bug #10252.
1508 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1510 * main.c (main): Set SHELL to v_noexport by default. Remember the
1511 original environment setting of SHELL in the env_shell variable.
1512 * main.h: Export new env_shell variable.
1513 * variable.c (target_environment): If we find a v_noexport
1514 variable for SHELL, add a SHELL variable with the env_shell value.
1515 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1516 * doc/make.texi (Variables/Recursion): Ditto.
1518 2004-11-28 Paul D. Smith <psmith@gnu.org>
1520 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1521 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1522 Patch by Alessandro Vesely.
1524 2004-11-12 Paul D. Smith <psmith@gnu.org>
1526 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1527 the command line if it's inside a string.
1528 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1530 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1532 * function.c (func_lastword): New function: return last word
1533 from the list of words.
1534 * doc/make.texi: Document $(lastword ). Fix broken links in
1535 Quick Reference section.
1537 2004-10-06 Paul D. Smith <psmith@gnu.org>
1539 Apply patch from Alessandro Vesely, provided with bug # 9748.
1540 Fix use of tmpnam() to work with Borland C.
1542 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1543 construction of a temporary filename, and call new function
1544 create_batch_filename().
1545 (create_batch_filename) [WINDOWS32]: New function to create a
1548 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1550 * read.c (record_target_var): Expand simple pattern-specific
1552 * variable.c (initialize_file_variables): Do not expand simple
1553 pattern-specific variable.
1555 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1557 * remake.c (update_file_1): When rebuilding makefiles inherit
1558 dontcare flag from a target that triggered update.
1560 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1562 * variable.c (initialize_file_variables): Mark pattern-specific
1563 variable as a per-target and copy export status.
1565 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1567 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1569 * implicit.c (pattern_search): When considering an implicit rule's
1570 prerequisite check that it is actually a target rather then
1571 just an entry in the file hashtable.
1573 2004-09-21 Paul D. Smith <psmith@gnu.org>
1575 * read.c (readstring): Fix some logic errors in backslash handling.
1576 (eval): Remove some unnecessary processing in buffer handling.
1577 (record_target_var): Assert that parse_variable_definition() succeeded.
1578 Reported by: Markus Mauhart <qwe123@chello.at>.
1580 * misc.c: Removed the sindex() function. All instances of this
1581 function were trivially replaceable by the standard strstr()
1582 function, and that function will always have better (or certainly
1583 no worse) performance than the very simple-minded algorithm
1584 sindex() used. This can matter with complex makefiles.
1585 * make.h: Remove the prototype for sindex().
1586 * function.c (subst_expand): Convert sindex() call to strstr().
1587 This means we no longer need to track the TLEN value so remove that.
1588 (func_findstring): Convert sindex() to strstr().
1589 * commands.c (chop_commands): Convert sindex() calls to strstr().
1590 Suggested by: Markus Mauhart <qwe123@chello.at>.
1592 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1593 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1594 If SHELL is set to CMD.EXE then assume it's batch-mode and
1595 non-unixy. I wrote the code differently from the patch, though,
1596 to make it safer. This also resolves bug #9174.
1598 2004-09-20 Paul D. Smith <psmith@gnu.org>
1600 * expand.c (variable_expand_string): Modify to invoke
1601 patsubst_expand() instead of subst_expand(); the latter didn't
1602 handle suffix patterns correctly.
1603 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1604 was used only from variable_expand_string() and is no longer used
1606 (func_subst): Ditto, on call to subst_expand().
1607 (patsubst_expand): Require the percent pointers to point to the
1608 character after the %, not to the % itself.
1609 * read.c (record_files): New call criteria for patsubst_expand().
1610 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1611 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1613 2004-09-19 Paul D. Smith <psmith@gnu.org>
1615 * function.c (subst_expand): Fix a check in by_word: look for a
1616 previous blank if we're beyond the beginning of the string, not
1617 the beginning of the word.
1618 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1620 2004-05-16 Paul D. Smith <psmith@gnu.org>
1622 * remake.c (update_goal_chain): Change the argument specifying
1623 whether we're rebuilding makefiles to be a global variable,
1624 REBUILDING_MAKEFILES.
1625 (complain): Extract the code that complains about no rules to make
1626 a target into a separate function.
1627 (update_file_1): If we tried to rebuild a file during the makefile
1628 rebuild phase and it was dontcare, then no message was printed.
1629 If we then try to build the same file during the normal build,
1630 print a message this time.
1631 (remake_file): Don't complain about un-remake-able files when
1632 we're rebuilding makefiles.
1634 2004-05-11 Paul D. Smith <psmith@gnu.org>
1636 * job.c (construct_command_argv_internal): OS/2 patches from
1637 Andreas Buening <andreas.buening@nexgo.de>.
1639 2004-05-10 Paul D. Smith <psmith@gnu.org>
1641 * remake.c (update_file): Don't walk the double-colon chain unless
1642 this is a double-colon rule. Fix suggested by Boris Kolpackov
1643 <boris@kolpackov.net>.
1645 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1646 * readme.vms: New section describing OpenVMS support and issues.
1647 * default.c (default_variables): Add support for IA64.
1648 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1649 without some privilege aborts make with the error
1650 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1651 pressing Ctrl+Y and the input device is no terminal. The change
1652 catches this error and just continues.
1654 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1656 2004-04-25 Paul D. Smith <psmith@gnu.org>
1658 * commands.c (set_file_variables): Set $< properly in the face of
1659 order-only prerequisites.
1660 Patch from Boris Kolpackov <boris@kolpackov.net>
1662 2004-04-21 Bob Byrnes <byrnes@curl.com>
1664 * main.c (main): Notice failures to remake makefiles.
1666 2004-03-28 Paul D. Smith <psmith@gnu.org>
1668 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1670 * job.c: No default shell for RISC OS.
1671 (load_too_high): Hard-code the return to 1.
1672 (construct_command_argv_internal): No sh_chars or sh_cmds.
1673 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1675 2004-03-20 Paul D. Smith <psmith@gnu.org>
1677 * variable.c (do_variable_definition): Don't append from the
1678 global set if a previous non-appending target-specific variable
1679 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1682 * expand.c (reference_variable): Don't give up on variables with
1683 no value that have the target-specific append flag set: they might
1684 have a value after all. Reported by Oliver Schmidt
1685 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1686 <nikulin@dx1cmd.inp.nsk.su>.
1688 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1689 refer to absolute pathnames in directories that don't exist: some
1690 portion of the makefile could create those directories before we
1691 match the pattern. Fixes bugs #775 and #108.
1693 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1695 * main.c (main): Free makefile_mtimes if we have any.
1696 * README.W32.template: Update documentation for the current status
1697 of the MS-Windows port.
1698 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1699 environment variable is sometimes already defined which causes the
1701 * main.c (debug_signal_handler): Only define this function if
1702 SIGUSR1 is available.
1704 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1706 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1707 * README.OS2.template: Documentation updates.
1708 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1709 link line for safety.
1710 * maintMakefile (build.sh.in): Remove an extraneous ")".
1711 * job.c (child_execute_job): Close saved FDs.
1712 * job.c (exec_command) [OS/2]: exec_command(): If the command
1713 can't be exec'ed and if the shell is not Unix-sh, then try again
1714 with argv = { "cmd", "/c", ... }. Normally, this code is never
1715 reached for the cmd shell unless the command really doesn't exist.
1716 (construct_command_argv_internal) [OS/2]: The code for cmd
1717 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1718 The CMD builtin commands are case insensitive so use strcasecmp().
1720 2004-03-19 Paul D. Smith <psmith@gnu.org>
1722 * read.c (do_define): Re-order line counter increment so the count
1723 is accurate (we were losing one line per define). Reported by
1724 Dave Yost <Dave@Yost.com>.
1726 2004-03-06 Paul D. Smith <psmith@gnu.org>
1728 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1730 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1731 * misc.c (message,error,fatal): Ditto.
1732 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1733 * config.h.W32.template: Ditto.
1734 * config.h-vms.template: Ditto.
1735 * config.ami.template: Ditto.
1737 2004-03-04 Paul D. Smith <psmith@gnu.org>
1739 * README.template: Add a note about broken /bin/sh on SunOS
1740 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1742 * misc.c (message, error, fatal): Don't use "..." if we're using
1743 varargs. ansi2knr should handle this but it doesn't work: it
1744 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1745 done. On many systems (SunOS for example) va_dcl is a #define.
1746 So, force the use of the non-"..." version on pre-ANSI compilers.
1748 * maintMakefile (sign-dist): Create some rules to help automate
1749 the new GNU ftp upload method.
1751 2004-02-24 Paul D. Smith <psmith@gnu.org>
1753 * config.h.W32.template: Add HAVE_STDARG_H
1754 * config.h-vms.template: Ditto.
1755 * config.ami.template: Ditto.
1757 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1759 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1760 * build_w32.bat: Remove extra "+".
1762 2004-02-23 Paul D. Smith <psmith@gnu.org>
1764 * make.h: Create an UNUSED macro to mark unused parameters.
1765 * (many): Clean up warnings by applying UNUSED, fixing
1766 signed/unsigned incompatibilities, etc.
1768 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1770 * filedef.h: Name the command_state enumeration.
1771 * file.c (set_command_state): Use the enumeration in the function
1774 * configure.in: Explicitly set SET_MAKE to empty, to disable
1775 MAKE=make even when no make already exists. Fix bug #3823.
1777 2004-02-22 Paul D. Smith <psmith@gnu.org>
1779 * maintMakefile: Perl script to clean up all non-CVS files. Use
1780 it on all the subdirectories for the cvs-clean target.
1782 * main.c (decode_switches): Require non-empty strings for all our
1783 string command-line options. Fixes Debian bug # 164165.
1785 * configure.in: Check for stdarg.h and varargs.h.
1786 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1787 for printing messages.
1788 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1793 A number of patches for OS/2 support from Andreas Buening
1794 <andreas.buening@nexgo.de>:
1796 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1797 disable the SIGCHLD handler.
1798 (reap_children) [OS/2]: Remove special handling of job_rfd.
1799 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1800 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1801 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1802 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1803 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1806 2004-02-21 Paul D. Smith <psmith@gnu.org>
1808 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1809 <mail@kristov.de> reports that if process_begin() fails we don't
1810 handle the error condition correctly in all cases.
1811 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1812 to have a newline on the message.
1814 * job.c (construct_command_argv_internal): Add "test" to UNIX
1815 sh_cmds[]. Fixes Savannah bug # 7606.
1817 2004-02-04 Paul D. Smith <psmith@gnu.org>
1819 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1820 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1821 Hartmut Becker <Hartmut.Becker@hp.com>.
1823 2004-01-21 Paul D. Smith <psmith@gnu.org>
1825 * job.c (load_too_high): Implement an algorithm to control the
1826 "thundering herd" problem when using -l to control job creation
1827 via the load average. The system only recomputes the load once a
1828 second but we can start many jobs in a second. To solve this we
1829 keep track of the number of jobs started in the last second and
1830 apply a weight to try to guess what a correct load would be.
1831 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1832 Also fixes bug #4693.
1833 (reap_children): Decrease the job count for this second.
1834 (start_job_command): Increase the job count for this second.
1836 * read.c (conditional_line): Expand the text after ifn?def before
1837 checking to see if it's a single word. Fixes bug #7257.
1839 2004-01-09 Paul D. Smith <psmith@gnu.org>
1841 * file.c (print_file): Recurse to print all targets in
1842 double-colon rules. Fixes bug #4518, reported (with patch) by
1843 Andrew Chatham <chatham@google.com>.
1845 2004-01-07 Paul D. Smith <psmith@gnu.org>
1847 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1848 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1849 AC_FUNC_SETVBUF_REVERSED.
1851 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1852 (MAKE Variable): Fix Savannah bug #4898.
1854 * job.c (construct_command_argv_internal): Add "!" to the list of
1855 shell escape chars. POSIX sh allows it to appear before a
1856 command, to negate the exit code. Fixes bug #6404.
1858 * implicit.c (pattern_search): When matching an implicit rule,
1859 remember which dependencies have the ignore_mtime flag set.
1860 Original fix provided in Savannah patch #2349, by Benoit
1861 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1863 2003-11-22 Paul D. Smith <psmith@gnu.org>
1865 * README.W32.template (Outputs): Clarification on -j with
1866 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1869 2003-11-02 Paul D. Smith <psmith@gnu.org>
1871 * function.c (func_if): Strip all the trailing whitespace from the
1872 condition, then don't expand it. Fixed bug # 5798.
1874 * expand.c (recursively_expand_for_file): If we're expanding a
1875 variable with no file context, then use the variable's context.
1878 2003-10-21 Paul D. Smith <psmith@gnu.org>
1880 * main.c (log_working_directory): Add newlines to printf()s.
1882 * README.cvs: Add a note to ignore warnings during autoreconf.
1884 * maintMakefile (po_repo): Set a new URL for PO file updates.
1885 (get-config/config.guess get-config/config.sub): Get these files
1886 from the Savannah config project instead of ftp.gnu.org.
1888 2003-10-05 Paul Eggert <eggert@twinsun.com>
1890 * main.c (main): Avoid potential subscript error if environ has
1893 2003-08-22 Paul D. Smith <psmith@gnu.org>
1895 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1896 systems which don't yet implement the C89 standard :-/.
1898 2003-07-18 Paul D. Smith <psmith@gnu.org>
1900 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1901 [WINDOWS32]: Initialize hash.
1903 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1905 * dir.c (read_dirstream): Provide a workaround for broken versions of
1906 the MinGW dirent structure.
1908 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1910 * w32/include/dirent.h: Add __MINGW32__ filter.
1912 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1914 * make.h: Add global declaration of *make_host.
1915 * main.c (print_usage): Remove local declaration of *make_host.
1916 (print_version): Display "This program built for ..." after Copyright
1919 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1921 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1922 execution of "makeinfo --html make.texi".
1924 2003-04-30 Paul D. Smith <psmith@gnu.org>
1926 * build.template: Make some changes to maybe allow this script to
1927 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1929 * README.OS2.template: New file for OS/2 support. Original
1930 contributed by Andreas Buening.
1931 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1934 2003-04-19 Paul D. Smith <psmith@gnu.org>
1936 Fix bug #1405: allow a target to match multiple pattern-specific
1939 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1940 variable.c, where they've always belonged.
1941 * rule.h: Move the prototypes and struct pattern_var as well.
1942 * variable.c (initialize_file_variables): Invoke
1943 lookup_pattern_var() in a loop, until no more matches are found.
1944 If a match is found, create a new variable set for the target's
1945 pattern variables. Then merge the contents of each matching
1946 pattern variable set into the target's pattern variable set.
1947 (lookup_pattern_var): Change this function to be usable
1948 in a loop. It takes a starting position: if NULL, start at the
1949 beginning; if non-NULL, start with the pattern variable after that
1950 position, and return the next matching pattern.
1951 (create_pattern_var): Create a unique instance of
1952 pattern-specific variables for every definition in the makefile.
1953 Don't combine the same pattern together. This allows us to
1954 process the variable handling properly even when the same pattern
1955 is used multiple times.
1956 (parse_variable_definition): New function: break out the parsing
1957 of a variable definition line from try_variable_definition.
1958 (try_variable_definition): Call parse_variable_definition to
1960 (print_variable_data_base): Print out pattern-specific variables.
1961 * variable.h (struct variable): Remember when a variable is
1962 conditional. Also remember its flavor.
1963 (struct pattern_var): Instead of keeping a variable set, we just
1964 keep a single variable for each pattern.
1965 * read.c (record_target_var): Each pattern variable contains only a
1966 single variable, not a set, so create it properly.
1967 * doc/make.texi (Pattern-specific): Document the new behavior.
1969 2003-04-17 Paul D. Smith <psmith@gnu.org>
1971 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1972 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1973 file/directory naming rules for VMS so I can't tell whether this
1976 2003-04-09 Paul D. Smith <psmith@gnu.org>
1978 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1979 DOS-style pathnames: backslash separators and drive specifiers.
1981 2003-03-28 Paul D. Smith <psmith@gnu.org>
1983 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1984 the intermediate flag on all targets. Fixes bug #2515.
1986 2003-03-24 Paul D. Smith <psmith@gnu.org>
1988 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1989 Upgrade to autoconf 2.57 and automake 1.7.3.
1991 * job.c: More OS/2 changes from Andreas Buening.
1993 * file.c (print_file): Fix variable initialization.
1996 * remake.c (notice_finished_file):
1998 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1999 some calls (like readdir()) return NULL in valid situations
2000 without resetting errno. Fixes bug #2846.
2002 2003-02-25 Paul D. Smith <psmith@gnu.org>
2004 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2006 * job.c (_is_unixy_shell) [OS/2]: New function.
2007 Set default shell to /bin/sh.
2008 (reap_children): Close the job_rfd pipe here since we don't use a
2010 (set_child_handler_action_flags): define this to empty on OS/2.
2011 (start_job_command): Close the jobserver pipe and use
2012 child_execute_job() instead of fork/exec.
2013 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2014 rather than exec'ing, then reconfigure stdin/stdout.
2015 (exec_command): Rewrite to use spawn instead of exec. Return the
2018 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2019 in DOS. Handle the TEMP environment variable as in DOS. Don't
2020 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2021 use -j in DOS mode. Use child_execute_job() instead of
2024 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2027 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2028 prototypes that return values.
2030 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2032 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2033 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2035 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2038 2003-02-24 Paul D. Smith <psmith@gnu.org>
2040 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2041 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2042 (child_execute_job) [VMS]: Handle error status properly.
2043 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2045 * function.c (func_shell): Use EINTRLOOP() while reading from the
2046 subshell pipe (Fixes bug #2502).
2047 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2049 * main.c (main): Ditto.
2051 2003-01-30 Paul D. Smith <psmith@gnu.org>
2053 * read.c (eval): eval() was not fully reentrant, because the
2054 collapsed buffer was static. Change it to be an automatic
2055 variable so that eval() can be invoked recursively.
2057 (eval): Apply patch # 1022: fix memory reference error on long
2058 target-specific variable lines.
2059 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2061 * function.c (check_numeric): Combine the is_numeric() function
2062 into this function, since it's only called from one place.
2063 Constify this function. Have it print the incorrect string in the
2064 error message. Fixes bug #2407.
2065 (strip_whitespace): Constify.
2066 (func_if): Constify.
2067 * expand.c (expand_argument): Constify.
2069 2003-01-29 Paul D. Smith <psmith@gnu.org>
2071 Fix bug # 2169, also reported by other people on various systems.
2073 * make.h: Some systems, such as Solaris and PTX, do not fully
2074 implement POSIX-compliant SA_RESTART functionality; important
2075 system calls like stat() and readdir() can still fail with EINTR
2076 even if SA_RESTART has been set on the signal handler. So,
2077 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2078 EINTR for system calls which return -1 or 0 (NULL), respectively,
2080 Also, remove the old atomic_stat()/atomic_readdir() and
2081 HAVE_BROKEN_RESTART handling.
2083 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2085 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2086 * remake.c (touch_file): Ditto.
2088 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2089 * read.c (construct_include_path): Ditto.
2090 * remake.c (name_mtime): Ditto.
2091 * vpath.c (selective_vpath_search): Ditto.
2092 * dir.c (find_directory): Ditto.
2093 (local_stat): Ditto.
2094 (find_directory): Use ENULLLOOP() to wrap opendir().
2095 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2097 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2098 atomic_readdir() handling.
2100 2003-01-22 Paul D. Smith <psmith@gnu.org>
2102 * function.c (func_call): Fix Bug #1744. If we're inside a
2103 recursive invocation of $(call ...), mask any of the outer
2104 invocation's arguments that aren't used by this one, so that this
2105 invocation doesn't "inherit" them accidentally.
2107 2002-12-05 Paul D. Smith <psmith@gnu.org>
2109 * function.c (subst_expand): Valery Khamenia reported a
2110 pathological performance hit when doing substitutions on very
2111 large values with lots of words: turns out we were invoking
2112 strlen() a ridiculous number of times. Instead of having each
2113 call to sindex() call strlen() again, keep track of how much of
2114 the text we've seen and pass the length to sindex().
2116 2002-11-19 Paul D. Smith <psmith@gnu.org>
2118 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2121 2002-11-16 Paul D. Smith <psmith@gnu.org>
2123 * NMakefile.template (OBJS): Add hash.c object file.
2124 * SMakefile.template (srcs): Ditto.
2125 * Makefile.ami (objs): Ditto.
2126 * build_w32.bat: Ditto.
2128 * Makefile.DOS.template: Remove extra dependencies.
2130 2002-10-25 Paul D. Smith <psmith@gnu.org>
2132 * expand.c (install_variable_buffer): New function. Install a new
2133 variable_buffer context and return the previous one.
2134 (restore_variable_buffer): New function. Free the current
2135 variable_buffer context and put a previously saved one back.
2136 * variable.h: Prototypes for {install,restore}_variable_buffer.
2137 * function.c (func_eval): Push a new variable_buffer context
2138 before we eval, then restore the old one when we're done.
2141 * read.c (install_conditionals): New function. Install a new
2142 conditional context and return the previous one.
2143 (restore_conditionals): New function. Free the current
2144 conditional context and put a previously saved one back.
2145 (eval): Use the {install,restore}_conditionals for "include"
2147 (eval_buffer): Use {install,restore}_conditionals to preserve the
2148 present conditional state before we evaluate the buffer.
2151 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2153 (Recursion): Add a variable index entry for CURDIR.
2155 * README.cvs: Update to appropriate versions.
2156 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2157 don't need to copy loadavg.c: automake is smart enough to create
2158 it for me. Still have a bug in automake related to ansi2knr tho.
2160 2002-10-14 Paul D. Smith <psmith@gnu.org>
2162 * remake.c (notice_finished_file): Only touch targets if they have
2163 at least one command (as per POSIX). Resolve Bug #1418.
2165 * *.c: Convert to using ANSI C-style function definitions.
2166 * Makefile.am: Enable the ansi2knr feature of automake.
2167 * configure.in: ditto.
2169 2002-10-13 Paul D. Smith <psmith@gnu.org>
2171 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2172 for automatic variable values like $^, etc. In the case of very
2173 large lists of prerequisites this causes problems. Instead reuse
2174 a static buffer (resizeable) for each variable.
2176 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2177 target-specific variable definitions. Check for it and set an
2179 (record_target_var): Set the export field to v_export if the
2180 "exported" flag is set.
2181 * doc/make.texi (Target-specific): Document the ability to use
2184 * doc/make.texi: Change the name of the section on automatic
2185 variables from "Automatic" to "Automatic Variables". Added text
2186 clarifying the scope of automatic variables.
2188 2002-10-04 Paul D. Smith <psmith@gnu.org>
2190 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2192 (record_files): Ditto.
2194 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2195 the search for the '=' to only within the enclosing parens.
2197 2002-10-03 Paul D. Smith <psmith@gnu.org>
2199 Version 3.80 released.
2201 * dir.c: Change hash functions to use K&R function definition style.
2202 * function.c: Ditto.
2204 * variable.c: Ditto.
2206 Update to automake 1.7.
2208 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2209 (pdf): Remove this target as automake now provides one.
2211 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2213 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2215 * makefile.com: Updates for GNU make 3.80.
2216 * makefile.vms: Ditto.
2218 2002-09-23 Paul D. Smith <psmith@gnu.org>
2220 * read.c (enum make_word_type): Remove w_comment.
2221 (get_next_mword): Don't treat comment characters as special; where
2222 this function is used we will never see a comment (it's stripped
2223 before we get here) and treating comments specially means that
2224 targets like "foo\#bar" aren't handled properly.
2226 2002-09-18 Paul D. Smith <psmith@gnu.org>
2228 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2230 * read.c (eval): Expansion of arguments to export/unexport was
2231 ignoring all arguments after the first one. Change the algorithm
2232 to expand the whole line once, then parse the results.
2234 2002-09-17 Paul D. Smith <psmith@gnu.org>
2236 Fix Bug #940 (plus another bug I found while looking at this):
2238 * read.c (record_target_var): enter_file() will add a new entry if
2239 it's a double-colon target: we don't want to do that in this
2240 situation. Invoke lookup_file() and only enter_file() if it does
2241 not already exist. If the file we get back is a double-colon then
2242 add this variable to the "root" double-colon target.
2244 * variable.c (initialize_file_variables): If this file is a
2245 double-colon target but is not the "root" target, then initialize
2246 the root and make the root's variable list the parent of our
2249 2002-09-13 Paul D. Smith <psmith@gnu.org>
2251 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2253 * hash.c (round_up_2): Get rid of a warning.
2255 2002-09-12 Paul D. Smith <psmith@gnu.org>
2257 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2258 so it doesn't complain about getloadavg.c.
2260 * commands.c (set_file_variables): Make sure we always alloca() at
2261 least 1 character for the value of $? (for '\0').
2263 2002-09-11 Paul D. Smith <psmith@gnu.org>
2265 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2266 macro to use RESULT instead of the incorrect _RESULT_.
2268 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2269 and atomic_readdir(). We need to #include dirent.h to get this to
2271 * misc.c (atomic_readdir): Fix typos.
2273 2002-09-10 Paul D. Smith <psmith@gnu.org>
2275 * read.c (eval): Expand variable lists given to export and
2276 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2277 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2279 * doc/make.texi (Variables/Recursion): Document this.
2280 (Conditional Syntax): And here.
2282 2002-09-09 Paul D. Smith <psmith@gnu.org>
2284 * configure.in: Check for memmove().
2286 2002-09-07 Paul D. Smith <psmith@gnu.org>
2288 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2289 Michael Sterrett <msterret@coat.com> reports that while it has
2290 SA_RESTART, it does not work properly.
2292 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2293 that invokes stat() and loops to do it again if it returns EINTR.
2294 (atomic_readdir): Ditto, with readdir().
2296 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2297 and readdir() to atomic_stat() and atomic_readdir().
2299 2002-09-04 Paul D. Smith <psmith@gnu.org>
2301 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2302 reports that GNU make sometimes doesn't recognize that targets can
2303 be made, when directories can be created as prerequisites. He
2304 reports that changing the order of predicates in the DEP->changed
2305 flag test so that lookup_file() is always performed, solves this
2308 2002-08-08 Paul D. Smith <psmith@gnu.org>
2310 * configure.in: Require a newer version of gettext.
2312 * misc.c (perror_with_name): Translate the format string (for
2313 right-to-left language support).
2314 (pfatal_with_name): Ditto.
2316 * main.c: Create a static array of strings to store the usage
2317 text. This is done to facilitate translations.
2318 (struct command_switch): Remove argdesc and description fields.
2319 (switches): Remove values for obsolete fields.
2320 (print_usage): Print each element of the usage array.
2322 * hash.c: Change function definitions to be K&R style.
2324 2002-08-02 Paul D. Smith <psmith@gnu.org>
2326 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2327 this one because it's too hard to get right. We'll look at it for
2329 * main.c (main): Don't create the .TARGETS variable.
2330 * variable.c (handle_special_var): Don't handle .TARGETS.
2332 2002-08-01 Paul D. Smith <psmith@gnu.org>
2334 * main.c (switches): Add a new option, -B (--always-make). If
2335 specified, make will rebuild all targets that it encounters even
2336 if they don't appear to be out of date.
2337 (always_make_flag): New flag.
2338 * make.h: Extern always_make_flag.
2339 * remake.c (update_file_1): Check always_make_flag; if it's set we
2340 will always rebuild any target we can, even if none of its
2341 prerequisites are newer.
2344 * doc/make.texi (Shell Function): Make it clear that make
2345 variables marked as "export" are not passed to instances of the
2348 Add new introspection variable .VARIABLES and .TARGETS.
2350 * variable.c (handle_special_var): New function. If the variable
2351 reference passed in is "special" (.VARIABLES or .TARGETS),
2352 calculate the new value if necessary. .VARIABLES is handled here:
2353 walk through the hash of defined variables and construct a value
2354 which is a list of the names. .TARGETS is handled by
2355 build_target_list().
2356 (lookup_variable): Invoke handle_special_var().
2357 * file.c (build_target_list): Walk through the hask of known files
2358 and construct a list of the names of all the ones marked as
2360 * main.c (main): Initialize them to empty (and as simple variables).
2361 * doc/make.texi (Special Variables): Document them.
2362 * NEWS: Mention them.
2364 * variable.h (struct variable): Add a new flag "exportable" which
2365 is true if the variable name is valid for export.
2366 * variable.c (define_variable_in_set): Set "exportable" when a new
2367 variable is defined.
2368 (target_environment): Use the "exportable" flag instead of
2369 re-checking the name here... an efficiency improvement.
2371 2002-07-31 Paul D. Smith <psmith@gnu.org>
2373 * config.h-vms.template: Updates to build on VMS. Thanks to
2374 Brian_Benning@aksteel.com for helping verify the build.
2375 * makefile.com: Build the new hash.c file.
2376 * hash.h: Use strcpmi(), not stricmp(), in the
2377 HAVE_CASE_INSENSITIVE_FS case.
2379 2002-07-30 Paul D. Smith <psmith@gnu.org>
2381 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2382 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2383 Reported by <Brian_Benning@aksteel.com>.
2385 2002-07-10 Paul D. Smith <psmith@gnu.org>
2387 * variable.c (pop_variable_scope): Remove variable made unused by
2388 new hash infrastructure.
2389 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2390 comparisons as well as name comparisons.
2391 * variable.h: Add a prototype for new hash_init_function_table().
2392 * file.c (lookup_file): Remove variables made unused by new hash
2394 * dir.c (directory_contents_hash_2): Missing return of hash value.
2395 (dir_contents_file_exists_p): Remove variables made unused by new
2396 hash infrastructure.
2399 Installed Greg McGary's integration of the hash functions from the
2400 GNU id-utils package:
2402 2002-07-10 Greg McGary <greg@mcgary.org>
2404 * scripts/functions/filter-out: Add literals to to the
2405 pattern space in order to add complexity, and trigger
2406 use of an internal hash table. Fix documentation strings.
2407 * scripts/targets/INTERMEDIATE: Reverse order of files
2408 passed to expected `rm' command.
2410 2002-07-10 Greg McGary <greg@mcgary.org>

2502 2002-07-10 Paul D. Smith <psmith@gnu.org>
2504 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2505 prerequisite list. A real SysV make will expand the entire
2506 prerequisites list _twice_: we don't do that as it's a big
2507 backward-compatibility problem. We only replace those specific
2510 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2511 references left in the list of prerequisites. Check for .POSIX as
2512 we record targets, so we can disable non-POSIX behavior while
2513 reading makefiles as well as running them.
2514 (eval): Check the prerequisite list to see if we have anything
2515 that looks like a SysV prerequisite variable reference.
2517 2002-07-09 Paul D. Smith <psmith@gnu.org>
2519 * doc/make.texi (Prerequisite Types): Add a new section describing
2520 order-only prerequisites.
2522 * read.c (uniquize_deps): If we have the same file as both a
2523 normal and order-only prereq, get rid of the order-only prereq,
2524 since the normal one supersedes it.
2526 2002-07-08 Paul D. Smith <psmith@gnu.org>
2528 * AUTHORS: Added Greg McGary to the AUTHORS file.
2529 * NEWS: Blurbed order-only prerequisites.
2530 * file.c (print_file): Show order-only deps properly when printing
2533 * maintMakefile: Add "update" targets for wget'ing the latest
2534 versions of various external files. Taken from Makefile.maint in
2537 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2538 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2540 2002-07-07 Paul D. Smith <psmith@gnu.org>
2542 * po/*.po: Remove. We'll use wget to retrieve them at release
2545 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2546 rather than a shell you get an exception. Make sure we look up
2547 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2549 * remake.c (notice_finished_file): Fix handling of -t flag.
2550 Patch provided by Henning Makholm <henning@makholm.net>.
2552 * implicit.c (pattern_search): Some systems apparently run short
2553 of stack space, and using alloca() in this function caused an
2554 overrun. I modified it to use xmalloc() on the two variables
2555 which seemed like they might get large. Fixes Bug #476.
2557 * main.c (print_version): Update copyright notice to conform with
2559 (print_usage): Update help output.
2561 * function.c (func_eval): Create a new make function, $(eval
2562 ...). Expand the arguments, put them into a buffer, then invoke
2563 eval_buffer() on the resulting string.
2564 (func_quote): Create a new function, $(quote VARNAME). Inserts
2565 the value of the variable VARNAME without expanding it any
2568 * read.c (struct ebuffer): Change the linebuffer structure to an
2569 "eval buffer", which can be either a file or a buffer.
2570 (eval_makefile): Move the code in the old read_makefile() which
2571 located a makefile into here: create a struct ebuffer with that
2572 information. Have it invoke the new function eval() with that
2574 (eval_buffer): Create a new function that creates a struct ebuffer
2575 that holds a string buffer instead of a file. Have it invoke
2576 eval() with that ebuffer.
2577 (eval): New function that contains the guts of the old
2578 read_makefile() function: this function parses makefiles. Obtains
2579 data to parse from the provided ebuffer. Some modifications to
2580 make the flow of the function cleaner and clearer. Still could
2581 use some work here...
2582 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2583 contents of the define/endef variable from the ebuffer.
2584 (readstring): Read the next line from a string-style ebuffer.
2585 (readline): Read the next line from an ebuffer. If it's a string
2586 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2589 * dep.h (eval_buffer): Prototype eval_buffer();
2591 * variable.c (do_variable_definition): Make sure that all
2592 non-target-specific variables are registered in the global set.
2593 If we're invoked from an $(eval ...) we might be inside a $(call
2594 ...) or other function which has pushed a variable scope; we still
2595 want to define our variables from evaluated makefile code in the
2598 2002-07-03 Greg McGary <greg@mcgary.org>
2600 * dep.h (struct dep) [ignore_mtime]: New member.
2601 [changed]: convert to a bitfield.
2602 * implicit.c (pattern_search): Zero ignore_mtime.
2603 * main.c (main, handle_non_switch_argument): Likewise.
2604 * rule.c (convert_suffix_rule): Likewise.
2605 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2606 (read_makefile): Parse '|' in prerequisite list.
2607 (uniquize_deps): Consider ignore_mtime when comparing deps.
2608 * remake.c (update_file_1, check_dep): Don't force remake for
2609 dependencies that have d->ignore_mtime.
2610 * commands.c (FILE_LIST_SEPARATOR): New constant.
2611 (set_file_variables): Don't include a
2612 prerequisite in $+, $^ or $? if d->ignore_mtime.
2615 2002-06-18 Paul D. Smith <psmith@gnu.org>
2617 * make.texinfo: Updates for next revision. New date/rev/etc.
2618 Recreate all Info menus. Change license on the manual to the GNU
2619 Free Documentation License. A number of typos.
2620 (Variables Simplify): Don't use "-" before it's defined.
2621 (Automatic Prerequisites): Rewrite the target example to work
2622 properly if the compile fails. Remove incorrect comments about
2623 how "set -e" behaves.
2624 (Text Functions): Move the "word", "wordlist", "words", and
2625 "firstword" functions here, from "File Name Functions".
2626 * make-stds.texi: Update from latest GNU version.
2627 * fdl.texi: (created) Import the latest GNU version.
2629 2002-06-06 Paul D. Smith <psmith@gnu.org>
2631 * variable.c (do_variable_definition): New function: extract the
2632 part of try_variable_definition() that actually sets the value
2633 into a separate function.
2634 (try_variable_definition): Call do_variable_definition() after
2635 parsing the variable definition string.
2636 (define_variable_in_set): Make the name argument const.
2638 * variable.h (enum variable_flavor): Make public.
2639 (do_variable_definition): Create prototype.
2641 * read.c (read_all_makefiles): Create a new built-in variable,
2643 (read_makefile): Add each makefile read in to this variable value.
2645 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2647 * Makefile.DOS.template: Tweak according to changes in the
2648 distribution. Add back the dependencies of *.o files.
2650 * configh.dos.template: Synchronize with config.h.in.
2652 2002-05-09 Paul D. Smith <psmith@gnu.org>
2654 * file.c (file_timestamp_now): Use K&R function declaration.
2656 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2657 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2658 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2659 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2660 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2661 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2662 nlist.n_name is a pointer rather than an array.
2664 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2665 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2666 * configure.in: Use it instead of the old version.
2668 * main.c (main): Prefer setvbuf() to setlinebuf().
2670 2002-05-08 Paul D. Smith <psmith@gnu.org>
2672 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2673 (loadavg_LDADD): Ditto.
2675 2002-04-29 Paul D. Smith <psmith@gnu.org>
2677 * expand.c (recursively_expand_for_file): Rename
2678 recursively_expand() to recursively_expand_for_file() and provide
2679 an extra argument, struct file. If the argument is provided, set
2680 the variable scope to that of the file before expanding.
2681 * variable.h (recursively_expand): Make this a macro that invokes
2682 recursively_expand_for_file() with a NULL file pointer.
2683 * variable.c (target_environment): Call the renamed function and
2684 provide the current file context.
2685 Fixes Debian bug #144306.
2687 2002-04-28 Paul D. Smith <psmith@gnu.org>
2689 Allow $(call ...) user-defined variables to be self-referencing
2690 without throwing an error. Allows implementation of transitive
2691 closures, among other possibly useful things.
2692 Requested by: Philip Guenther <guenther@sendmail.com>
2694 * variable.h (struct variable): Add a new field: exp_count, and
2695 new macros to hold its size and maximum value.
2696 (warn_undefined): Make this a macro.
2697 * variable.c (define_variable_in_set): Initialize it.
2698 * expand.c (recursively_expand): If we detect recursive expansion
2699 of a variable, check the exp_count field. If it's greater than 0
2700 allow the recursion and decrement the count.
2701 (warn_undefined): Remove this (now a macro in variable.h).
2702 * function.c (func_call): Before we expand the user-defined
2703 function, modify its exp_count field to contain the maximum
2704 number of recursive calls we'll allow. After the call, reset it
2707 2002-04-21 Paul D. Smith <psmith@gnu.org>
2709 Modified to use latest autoconf (2.53), automake (1.6.1), and
2710 gettext (0.11.1). We're using gettext's new "external" support,
2711 to avoid including libintl source with GNU make.
2713 * README.cvs: New file. Explain how to build GNU make from CVS.
2715 * configure.in: Modify checking for the system glob library.
2716 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2717 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2718 etc. will manage it correctly). Set an automake conditional
2719 USE_LOCAL_GLOB to decide whether to compile the glob library.
2721 * getloadavg.c (main): Include make.h in the "TEST" program to
2724 * Makefile.am: Remove special rules for loadavg. Replace them
2725 with Automake capabilities for building extra programs.
2727 * signame.c: This file does nothing if the system provide
2728 strsignal(). If not, it implements strsignal(). If the system
2729 doesn't define sys_siglist, then we make our own; otherwise we use
2731 * signame.h: Removed.
2733 * main.c (main): No need to invoke signame_init(). Update copyright.
2735 * ABOUT-NLS: Removed.
2736 * gettext.c: Removed.
2737 * gettext.h: Get a simplified copy from the gettext package.
2739 * i18n/*.po: Moved to po/.
2742 * config/*: Created. Contains package configuration helper files.
2743 * config.guess, config.sub: Moved to config directory.
2745 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2746 Rework to use new-style autoconf features. Use the "external"
2747 mode for gettext. Make the build.sh config file conditional on
2748 whether build.sh.in exists, to avoid autoconf errors.
2749 * acinclude.m4: Removed almost all macros as being obsolete.
2750 Rewrote remaining macros to use AC_DEFINE.
2751 * acconfig.h: Removed.
2753 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2754 conditional to handle customs support. Remove special handling
2757 2002-04-20 Paul D. Smith <psmith@gnu.org>
2759 * function.c (func_call): Don't mark the argument variables $1,
2760 etc. as recursive. They've already been fully expanded so
2761 there's no need to do it again, and doing so strips escaped $'s.
2762 Reported by Sebastian Glita <glseba@yahoo.com>.
2764 * remake.c (notice_finished_file): Walk through double-colon
2765 entries via the prev field, not the next field!
2766 Reported by Greg McGary <greg@mcgary.org>.
2768 * main.c (main): If the user specifies -q and asks for a specific
2769 target which is a makefile, we got an assert. In that case it
2770 turns out we should continue normally instead.
2772 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2774 * i18n/he.po: Installed a new translation.
2776 2002-01-07 Paul D. Smith <psmith@gnu.org>
2778 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2780 2001-12-04 Paul D. Smith <psmith@gnu.org>
2782 * i18n/ja.po: Installed an updated translation.
2784 2001-09-06 Paul Eggert <eggert@twinsun.com>
2786 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2787 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2789 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2791 (main): Get rid of any avoidable limit on stack size.
2793 2001-09-04 Paul D. Smith <psmith@gnu.org>
2795 * i18n/da.po: Installed an updated translation.
2797 2001-08-03 Paul D. Smith <psmith@gnu.org>
2799 * i18n/fr.po: Installed an updated translation.
2800 Resolves Debian bug #106720.
2802 2001-06-13 Paul D. Smith <psmith@gnu.org>
2804 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2807 2001-06-11 Paul D. Smith <psmith@gnu.org>
2809 * i18n/ko.po: Installed a new translation.
2811 2001-05-06 Paul D. Smith <psmith@gnu.org>
2813 Modify the EINTR handling.
2815 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2816 the way in which we manage the file descriptor/signal handler race
2817 trap to be more efficient.
2819 2001-05-06 Paul Eggert <eggert@twinsun.com>
2821 Restart almost all system calls that are interrupted, instead
2822 of worrying about EINTR. The lone exception is the read() for
2825 * configure.in (HAVE_SA_RESTART): New macro.
2826 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2827 * main.c (main): Use SA_RESTART instead of the old,
2828 nonstandard SA_INTERRUPT.
2830 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2831 * main.c (bsd_signal): New function or macro,
2832 if the implementation doesn't supply it.
2833 (The bsd_signal function will be in POSIX 1003.1-200x.)
2834 (HANDLESIG): Remove.
2835 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2837 * make.h (EINTR_SET): Remove.
2838 (SA_RESTART): New macro.
2840 * arscan.c (ar_member_touch): Don't worry about EINTR.
2841 * function.c (func_shell): Likewise.
2842 * job.c (reap_children, free_child, new_job): Likewise.
2843 * main.c (main): Likewise.
2844 * remake.c (touch_file, name_mtime): Likewise.
2846 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2847 if fstat failed with errno!=EINTR, the error was ignored.
2849 * job.c (set_child_handler_action_flags): New function.
2850 (new_job): Use it to temporarily clear the SIGCHLD action flags
2851 while reading the token.
2853 2001-05-02 Paul D. Smith <psmith@gnu.org>
2855 * job.c (start_job_command): Don't add define/endef per-line flags
2856 to the top-level flags setting.
2858 2001-04-03 Paul D. Smith <psmith@gnu.org>
2860 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2861 bit on error, so check for odd return values, not non-0 return
2863 (VMS_get_member_info): Calculate the timezone differences correctly.
2864 Reported by John Fowler <jfowler@nyx.net>.
2867 2001-03-14 Paul D. Smith <psmith@gnu.org>
2869 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2870 value before invoking define_variable().
2871 Reported by John Fowler <jfowler@nyx.net>.
2873 2001-02-07 Paul D. Smith <psmith@gnu.org>
2875 * read.c (record_target_var): If we reset the variable due to a
2876 command-line variable setting overriding it, turn off the "append"
2879 2001-01-17 Paul D. Smith <psmith@gnu.org>
2881 * variable.c (lookup_variable) [VMS]: When getting values from the
2882 environment, allocate enough space for the _value_ plus escapes,
2883 not enough space for the name plus escapes :-/.
2884 Reported by John Fowler <jfowler@nyx.net>.
2886 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2887 warnings that make generates, so it doesn't look like an error.
2888 Reported by Karl Berry <karl@gnu.org>.
2891 Fix for PR/2020: Rework appended target-specific variables. I'm
2892 fairly confident this algorithm is finally correct.
2894 * expand.c (allocated_variable_append): Rewrite. Instead of
2895 expanding each appended variable then adding all the expanded
2896 strings together, we append all the unexpanded values going up
2897 through the variable set contexts, then expand the final result.
2898 This behaves just like non-target-specific appended variable
2899 values, while the old way didn't in various corner cases.
2900 (variable_append): New function: recursively append the unexpanded
2901 value of a variable, walking from the outermost variable scope to
2903 * variable.c (lookup_variable): Remove the code that looked up the
2904 variable set list if the found variable was "append". We don't
2906 (lookup_variable_in_set): Make this non-static so we can use it
2908 (try_variable_definition): Use lookup_variable_in_set() rather
2909 than faking out current_variable_set_list by hand (cleanup).
2910 * variable.h: Add a prototype for the now non-static
2911 lookup_variable_in_set().
2913 2000-11-17 Paul D. Smith <psmith@gnu.org>
2915 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2916 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2917 before throwing a fit.
2919 2000-11-17 Paul D. Smith <psmith@gnu.org>
2921 * read.c (readline): CRLF calculations had a hole, if you hit the
2922 buffer grow scenario just right. Reworked the algorithm to avoid
2923 the need for len or lastlen at all. Problem description with
2924 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2926 2000-10-24 Paul D. Smith <psmith@gnu.org>
2928 * gettext.c (SWAP): Declare this with the prototype, otherwise
2929 some systems don't work (non-32-bit? Reported for Cray T3E).
2930 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2932 2000-10-05 Paul D. Smith <psmith@gnu.org>
2934 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2935 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2937 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2939 2000-09-22 Paul D. Smith <psmith@gnu.org>
2941 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2942 parts of the real gettext.h here, and we expect to really include
2943 the real gettext.h later. If we keep this #define, it's ignored.
2945 2000-09-21 Paul D. Smith <psmith@gnu.org>
2947 * main.c (log_working_directory): Rework the text to use complete
2948 sentences, to make life simpler for the translators.
2950 2000-08-29 Paul D. Smith <psmith@gnu.org>
2952 * file.c (remove_intermediates): Print a debug message before we
2953 remove intermediate files, so the user (if she uses -d) knows
2956 2000-08-21 Paul D. Smith <psmith@gnu.org>
2958 * variable.c (try_variable_definition): Change how we handle
2959 target-specific append variable defns: instead of just setting the
2960 value, expand it as an append _but_ only within the current
2961 target's context. Otherwise we lose all but the last value if the
2962 variable is appended more than once within the current target
2963 context. Fixes PR/1831.
2965 2000-08-16 Paul D. Smith <psmith@gnu.org>
2967 * function.c (func_shell): Nul-terminate the buffer before
2968 printing an exec error message (just in case it's not!).
2969 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2971 2000-07-25 Paul D. Smith <psmith@gnu.org>
2973 * job.c (construct_command_argv_internal): Add "~" to the list of
2974 sh_chars[] which disallow optimizing out the shell call.
2976 2000-07-23 Paul Eggert <eggert@twinsun.com>
2978 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2979 supersedes --disable-nsec-timestamps.
2980 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2981 * README: Remove --disable-nsec-timestamps.
2983 * filedef.h (struct file.low_resolution_time): New member.
2984 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2985 * remake.c (update_file_1):
2986 Avoid spurious rebuilds due to low resolution time stamps,
2987 generalizing the earlier code that applied only to archive members.
2988 (f_mtime): Archive members always have low resolution time stamps.
2990 * configure.in: Remove --disable-nsec-timestamps, as this has
2991 been superseded by .LOW_RESOLUTION_TIME.
2993 2000-07-23 Paul Eggert <eggert@twinsun.com>
2995 * configure.in (enable_nsec_timestamps): Renamed from
2996 make_cv_nsec_timestamps, since enable/disable options
2997 shouldn't be cached.
2999 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3000 and Paul Eggert <eggert@twinsun.com>
3002 * file.c (file_timestamp_now):
3003 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3004 so that clock_gettime is not linked unless needed.
3006 * filedef.h (FILE_TIMESTAMP_HI_RES):
3007 Remove definition; "configure" now does this.
3009 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3010 to before high resolution file timestamp check,
3011 since that check now uses uintmax_t.
3012 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3013 high resolution file timestamps.
3014 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3015 so that we don't link in clock_gettime unnecessarily.
3017 2000-07-17 Paul D. Smith <psmith@gnu.org>
3019 * i18n/ja.po: New version of the translation file.
3021 2000-07-07 Paul D. Smith <psmith@gnu.org>
3023 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3024 the offset calculation.
3025 (name_mtime): Replace EINTR test with EINTR_SET macro.
3027 2000-07-07 Paul Eggert <eggert@twinsun.com>
3031 * remake.c (update_file_1):
3032 Avoid spurious rebuilds of archive members due to their
3033 timestamp resolution being only one second.
3034 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3035 the clock's resolution being lower than file timestamps'.
3036 When warning about future timestamps, report only the discrepancy,
3037 not the absolute value of the timestamp and the current time.
3039 * file.c (file_timestamp_now): New arg RESOLUTION.
3040 * filedef.h (file_timestamp_now): Likewise.
3041 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3043 2000-07-05 Paul D. Smith <psmith@gnu.org>
3045 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3046 to listp. Fixes PR/1793.
3048 2000-06-26 Paul Eggert <eggert@twinsun.com>
3050 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3052 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3054 * remake.c (f_mtime): Remove unused var memtime.
3056 2000-06-25 Martin Buchholz <martin@xemacs.org>
3058 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3059 Ran spell-check on make.texinfo.
3061 2000-06-23 Paul D. Smith <psmith@gnu.org>
3063 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3064 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3065 * make.h: Define these macros.
3067 * Version 3.79.1 released.
3069 * configure.in: Add a new option, --disable-nsec-timestamps, to
3070 avoid using sub-second timestamps on systems that support it. It
3071 can lead to problems, e.g. if your makefile relies on "cp -p".
3072 * README.template: Document the issue with "cp -p".
3074 * config.guess, config.sub: Updated.
