26 a more complex value than a simple shell: if it's not a default

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

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

305 2006-04-20 Paul D. Smith <psmith@gnu.org>
307 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
308 that don't have extended grep.
309 (cvsclean): Use $(PERL) instead of perl.
311 2006-04-09 Paul D. Smith <psmith@gnu.org>

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

377 Declare and define sh_chars_sh[].
379 2006-03-23 Paul D. Smith <psmith@gnu.org>
381 * configure.in: Look for build.sh.in in $srcdir so it will be
382 built for remote configurations as well.
384 * Makefile.am: Make sure to clean up build.sh during distclean.
385 Fixes Savannah bug #16166.
387 * misc.c (log_access): Takes a const char *.
388 * function.c (fold_newlines): Takes an unsigned int *.

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

468 * commands.c (set_file_variables): Realloc, not malloc, the static
469 string values to avoid memory leaks.
471 * expand.c (recursively_expand_for_file): Only set reading_file to
472 an initialized value.
474 * implicit.c (pattern_search): We need to make a copy of the stem
475 if we get it from an intermediate dep, since those get freed.

486 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
487 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
488 the calls to _beginthreadex.
490 * expand.c (recursively_expand_for_file): Initialize `save' to
491 prevent compiler warnings.

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

535 an impossible file, free it.

544 archive support is enabled.

559 A new internal capability: the string cache is a read-only cache
560 of strings, with a hash table interface for fast lookup. Nothing
561 in the cache will ever be freed, so there's no need for reference
562 counting, etc. This is the beginning of a full solution for
563 Savannah bug #15182, but for now we only store makefile names here.
565 * strcache.c: New file. Implement a read-only string cache.
566 * make.h: Add prototypes for new functions.
567 * main.c (initialize_global_hash_tables): Initialize the string cache.
568 (print_data_base): Print string cache stats.
569 * read.c (eval_makefile): Use the string cache to store makefile
570 names. Rewrite the string allocation to be sure we free everything.
572 2006-02-10 Eli Zaretskii <eliz@gnu.org>
574 * dir.c (dir_contents_file_exists_p): Don't opendir if the
575 directory time stamp didn't change, except on FAT filesystems.
576 Suggested by J. David Bryan <jdbryan@acm.org>.
578 2006-02-09 Paul D. Smith <psmith@gnu.org>
580 * function.c (func_or): Implement a short-circuiting OR function.
581 (func_and): Implement a short-circuiting AND function.
582 (function_table_init): Update the table with the new functions.
583 * doc/make.texi (Conditional Functions): Changed the "if" section
584 to one on general conditional functions. Added documentation for
585 $(and ...) and $(or ...) functions.
586 * NEWS: Note new $(and ...) and $(or ...) functions.
588 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
590 * job.h (struct child): Add the dontcare bitfield.
591 * job.c (new_job): Cache dontcare flag.
592 * job.c (reap_children): Use cached dontcare flag instead of the
593 one in struct file. Fixes Savannah bug #15641.
595 2006-02-06 Paul D. Smith <psmith@gnu.org>
597 * vpath.c (selective_vpath_search): If the file we find has a
598 timestamp from -o or -W, use that instead of the real time.
599 * remake.c (f_mtime): If the mtime is a special token from -o or
600 -W, don't overwrite it with the real mtime.
601 Fixes Savannah bug #15341.
603 Updates from Markus Mauhart <qwe123@chello.at>:

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

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

661 available number of slots.
662 (process_easy): Don't start new processes if all slots are used up.
664 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
665 are already more children than sub_proc.c can handle, behave as if
666 the load were too high.
667 (start_job_command): Fix a typo in error message when process_easy
670 2006-01-14 Eli Zaretskii <eliz@gnu.org>
672 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
673 the shell is not sh.exe.
675 * job.c (create_batch_file): Renamed from create_batch_filename;
676 all callers changed. Don't close the temporary file; return its
677 file descriptor instead. New arg FD allows to return the file
679 (construct_command_argv_internal): Use _fdopen instead of fopen to
682 2006-01-04 Paul D. Smith <psmith@gnu.org>
684 * readme.vms: Updates for case-insensitive VMS file systems from
685 Hartmut Becker <Hartmut.Becker@hp.com>.

696 * remake.c (update_file_1): Mark a prerequisite changed if it
699 * read.c (eval): Be sure to strip off trailing whitespace from the
700 prerequisites list properly. Also, initialize all fields in
701 struct dep when creating a new one.
703 2005-12-28 Paul D. Smith <psmith@gnu.org>
705 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
706 disable warnings for MSC.
707 Patch by Rob Tulloh <rtulloh@yahoo.com>.
709 2005-12-17 Eli Zaretskii <eliz@gnu.org>
711 * doc/make.texi (Execution): Add a footnote about changes in
712 handling of backslash-newline sequences. Mention the differences
713 on MS-DOS and MS-Windows.
715 * NEWS: More details about building the MinGW port and a pointer
716 to README.W32. Fix the section name that describes the new
717 backward-incompatible processing of backslash-newline sequences.
718 The special processing of SHELL set to "cmd" is only relevant to
719 MS-Windows, not MS-DOS.
721 2005-12-17 Eli Zaretskii <eliz@gnu.org>
723 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
724 to DWORD, to avoid compiler warnings.
725 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
726 use %ld in format, to avoid compiler warnings.

742 garbage happened to be on the heap.
744 2005-12-12 Paul D. Smith <psmith@gnu.org>
746 * make.1: Fix some display errors and document all existing options.
747 Patch provided by Mike Frysinger <vapier@gentoo.org>.
749 2005-12-11 Paul D. Smith <psmith@gnu.org>
751 * implicit.c (pattern_search): If 2nd expansion is not set for
752 this implicit rule, replace the pattern with the stem directly,
753 and don't re-expand the variable list. Along with the other
754 .SECONDEXPANSION changes below, fixes bug #13781.
756 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
758 * implicit.c (pattern_search): Mark other files that this rule
759 builds as targets so that they are not treated as intermediates
760 by the pattern rule search algorithm. Fixes bug #13022.
762 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
764 * remake.c (notice_finished_file): Propagate the change of
765 modification time to all the double-colon entries only if

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

810 * misc.c (free_dep_chain): New function: frees a struct dep list.
811 * read.c (read_all_makefiles): Initialize the staticpattern field.
812 (eval_makefile): Ditto.
813 (record_files): Check for the .SECONDEXPANSION target and set
814 second_expansion global if it's found.
815 Use the new free_dep_chain() instead of doing it by hand.
816 Set the staticpattern field for prereqs of static pattern targets.
818 2005-10-16 Paul D. Smith <psmith@gnu.org>
820 * main.c (main): Set CURDIR to be a file variable instead of a
821 default, so that values of CURDIR inherited from the environment
822 won't override the make value.
824 2005-09-26 Paul D. Smith <psmith@gnu.org>
826 * job.c (construct_command_argv_internal): If the line is empty
827 remember to free the temporary argv strings.
830 2005-09-16 Paul D. Smith <psmith@gnu.org>
832 * job.c (start_job_command): The noerror flag is a boolean (single
833 bit); set it appropriately.
834 Reported by Mark Eichin <eichin@metacarta.com>
836 2005-08-29 Paul D. Smith <psmith@gnu.org>
838 * function.c (func_error): On Windows, output from $(info ...)
839 seems to come in the wrong order. Try to force it with fflush().
841 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
843 * read.c (record_files): Move code that sets stem for static
844 pattern rules out of the if (!two_colon) condition so it is
845 also executed for two-colon rules. Fixes Savannah bug #13881.
847 2005-08-08 Paul D. Smith <psmith@gnu.org>
849 * make.h: Don't test that __STDC__ is non-0. Some compilers
850 (Windows for example) set it to 0 to denote "ISO C + extensions".
853 2005-08-07 Paul D. Smith <psmith@gnu.org>
855 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
856 conditional (slightly different version of a fix from Eli).
858 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
859 If make is running in parallel without -k and two jobs die in a
860 row, but not too close to each other, then make will quit without
861 waiting for the rest of the jobs to die.
863 * main.c (die): Don't reset err before calling reap_children() the
864 second time: we still want it to be in the error condition.
865 * job.c (reap_children): Use a static variable, rather than err,
866 to control whether or not the error message should be printed.
868 2005-08-06 Eli Zaretskii <eliz@gnu.org>
870 * w32/subproc/sub_proc.c: Include signal.h.
871 (process_pipe_io, process_file_io): Pass a pointer to a local
872 DWORD variable to GetExitCodeProcess. If the exit code is
873 CONTROL_C_EXIT, put SIGINT into pproc->signal.
875 * job.c [WINDOWS32]: Include windows.h.
876 (main_thread) [WINDOWS32]: New global variable.
877 (reap_children) [WINDOWS32]: Get the handle for the main thread
878 and store it in main_thread.
880 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
881 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
882 doing anything else. When we are done, close the main thread
883 handle and exit with status 130.
885 2005-07-30 Eli Zaretskii <eliz@gnu.org>
887 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
890 * main.c (find_and_set_default_shell): If found a DOSish shell,
891 set sh_found and the value of default_shell, and report the
892 findings in debug mode.
894 * job.c (construct_command_argv_internal): Check unixy_shell, not
895 no_default_sh_exe, to decide whether to use Unixy or DOSish
898 * README.W32: Update with info about the MinGW build.
900 * build_w32.bat: Support MinGW.
902 * w32/subproc/build.bat: Likewise.
904 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
907 * function.c (windows32_openpipe): Fix format strings for printing
910 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
912 (start_job_command): Fix format string for printing the result of
914 (start_job_command) [WINDOWS32]: Do not define.
915 (exec_command): Fix format string for printing HANDLE args.
917 * main.c (handle_runtime_exceptions): Fix sprintf format strings
918 to avoid compiler warnings.
919 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
920 (Note: some of these fixes were submitted independently by J. Grant)
922 2005-07-30 J. Grant <jg@jguk.org>
924 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
925 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
926 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
928 2005-07-15 Paul Smith <psmith@gnu.org>
930 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
931 we don't have a POSIX shell, then revert to the old
932 backslash-newline behavior (where they are stripped).
935 2005-07-08 Paul D. Smith <psmith@gnu.org>
937 * config.h.W32.template: Reorder to match the standard config.h,
938 for easier comparisons.
939 From J. Grant <jg@jguk.org>
941 * maintMakefile: Remove .dep_segment before overwriting it, in
942 case it's not writable or noclobber is set.
943 * expand.c (variable_expand_string): Cast result of pointer
944 arithmetic to avoid a warning.
945 * main.c (switches): Add full-fledged final initializer.
947 2005-07-06 Paul D. Smith <psmith@gnu.org>
949 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
950 * signame.c (strsignal): If we found _sys_siglist[] or
951 __sys_siglist[] use those instead of sys_siglist[].
952 From Albert Chin <china@thewrittenword.com>
954 2005-07-04 Paul D. Smith <psmith@gnu.org>
956 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
957 globfree(); set up to use the GNU versions.
958 From Martin Zinser <zinser@zinser.no-ip.info>
960 2005-07-03 Paul D. Smith <psmith@gnu.org>
962 From J. Grant <jg@jguk.org>:
964 * README.W32.template: Update the Windows and tested MSVC versions.
965 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
966 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
967 * build_w32.bat: Ditto.
968 * w32/subproc/build.bat: Ditto.
970 2005-06-28 Paul D. Smith <psmith@gnu.org>
972 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
973 declaration was checked but not present.
975 2005-06-27 Paul D. Smith <psmith@gnu.org>
977 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
978 to unsigned long. Fixes Savannah bug #13550.
980 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
981 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
982 Fixes Savannah bug #13551.
984 2005-06-26 Paul D. Smith <psmith@gnu.org>
986 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
987 it if ANSI_STRING is not set.
989 2005-06-25 Paul D. Smith <psmith@gnu.org>
991 * read.c (eval): If no filenames are passed to any of the
992 "include" variants, don't print an error.
993 * doc/make.texi (Include): Document this.
994 Fixes Savannah bug #1761.
996 * job.c (construct_command_argv_internal): Sanitize handling of
997 backslash/newline pairs according to POSIX: that is, keep the
998 backslash-newline in the command script, but remove a following
999 TAB character, if present. In the fast path, make sure that the
1000 behavior matches what the shell would do both inside and outside
1001 of quotes. In the slow path, quote the backslash and put a
1002 literal newline in the string.
1003 Fixes Savannah bug #1332.
1004 * doc/make.texi (Execution): Document the new behavior and give
1006 * NEWS: Make a note of the new behavior.
1008 * make.h [WINDOWS32]: #include <direct.h>.
1009 Fixes Savannah bug #13478.
1011 * remake.c (name_mtime): If the stat() of a file fails and the -L
1012 option was given and the file is a symlink, take the best mtime of
1013 the symlink we can get as the mtime of the file and don't fail.
1014 Fixes Savannah bug #13280.
1016 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1017 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1018 inside a variable reference. Make this function static as it's
1020 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1021 parsing an unexpanded line looking for semicolons.
1022 Fixes Savannah bug #1454.
1023 * misc.c (remove_comments): Move this to read.c and make it static
1024 as it's only used there. Call find_char_unquote() with new arg.
1025 * make.h: Remove prototypes for find_char_unquote() and
1026 remove_comments() since they're static now.
1028 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1029 its export flag and obtain its value. When we need to re-exec,
1030 increment the value and add it into the environment.
1031 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1032 * NEWS: Mention MAKE_RESTARTS.
1033 * main.c (always_make_set): New variable. Change the -B option to
1034 set this one instead.
1035 (main): When checking makefiles, only set always_make_flag if
1036 always_make_set is set AND the restarts flag is 0. When building
1037 normal targets, set it IFF always_make_set is set.
1038 (main): Avoid infinite recursion with -W, too: only set what-if
1039 files to NEW before we check makefiles if we've never restarted
1040 before. If we have restarted, set what-if files to NEW _after_ we
1042 Fixes Savannah bug #7566:
1044 2005-06-17 Paul D. Smith <psmith@gnu.org>
1046 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1047 in the prerequisites list.
1049 2005-06-12 Paul D. Smith <psmith@gnu.org>
1051 Fix Savannah bug # 1328.
1053 * configure.in: Check for atexit().
1054 * misc.c (close_stdout): Test stdout to see if writes to it have
1055 failed. If so, be sure to exit with a non-0 error code. Based on
1056 code found in gnulib.
1057 * make.h: Prototype.
1058 * main.c (main): Install close_stdout() with atexit().
1060 2005-06-10 Paul D. Smith <psmith@gnu.org>
1062 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1064 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1065 headers; make vmsWaitForChildren() static; extern vmsify().
1066 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1067 Don't create child_execute_job() here (it's in vmsjobs.c).
1068 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1070 2005-06-09 Paul D. Smith <psmith@gnu.org>
1072 * variable.c (push_new_variable_scope): File variables point
1073 directly to the global_setlist variable. So, inserting a new
1074 scope in front of that has no effect on those variables: they
1075 don't go through current_variable_set_list. If we're pushing a
1076 scope and the current scope is global, push it "the other way" so
1077 that the new setlist is in the global_setlist variable, and
1078 next points to a new setlist with the global variable set.
1079 (pop_variable_scope): Properly undo a push with the new
1081 Fixes Savannah bug #11913.
1083 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1085 * job.c (reap_children): Don't die of the command failed but
1086 the dontcare flag is set. Fixes Savannah bug #13216.
1088 * implicit.c (pattern_search): When creating a target from
1089 an implicit rule match, lookup pattern target and set precious
1090 flag in a newly created target. Fixes Savannah bug #13218.
1092 2005-05-13 Paul D. Smith <psmith@gnu.org>
1094 Implement "if... else if... endif" syntax.
1096 * read.c (eval): Push all checks for conditional words ("ifeq",
1097 "else", etc.) down into the conditional_line() function.
1098 (conditional_line): Rework to allow "else if..." clause. New
1099 return value -2 for lines which are not conditionals. The
1100 ignoring flag can now also be 2, which means "already parsed a
1101 true branch". If that value is seen no other branch of this
1102 conditional can be considered true. In the else parsing if there
1103 is extra text after the else, invoke conditional_line()
1104 recursively to see if it's another conditional. If not, it's an
1105 error. If so, raise the conditional value to this level instead
1106 of creating a new conditional nesting level. Special check for
1107 "else" and "endif", which aren't allowed on the "else" line.
1108 * doc/make.texi (Conditional Syntax): Document the new syntax.
1110 2005-05-09 Paul D. Smith <psmith@gnu.org>
1112 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1113 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1114 recurses to the w32 directory, even on non-Windows systems. Use
1115 the method suggested in the automake manual.
1116 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1117 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1119 2005-05-07 Paul D. Smith <psmith@gnu.org>
1121 * main.c (die): If we're dying with a fatal error (not that a
1122 command has failed), write back any leftover tokens before we go.
1124 * job.c (set_child_handler_action_flags): If there are jobs
1125 waiting for the load to go down, set an alarm to go off in 1
1126 second. This allows us to wake up from a potentially long-lasting
1127 read() and start a new job if the load has gone down. Turn it off
1129 (job_noop): Dummy signal handler function.
1130 (new_job): Invoke it with the new semantics.
1132 * docs/make.texi: Document secondary expansion. Various cleanups
1135 2005-05-03 Paul D. Smith <psmith@gnu.org>
1137 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1138 the targets which are to ultimately be made are called "goals";
1139 see the GNU make manual. Also, MAKECMDGOALS, etc.
1141 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1142 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1143 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1145 2005-05-02 Paul D. Smith <psmith@gnu.org>
1147 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1148 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1149 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1150 functions to vmsjobs.c. #include it into jobs.c.
1152 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1153 jobserver tokens. I found that this happens when an exported
1154 recursive variable contains a $(shell ...) function reference: in
1155 this situation we could "forget" to write back a token.
1157 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1158 we have. It's not reliable to depend on the number of children in
1159 our linked list so keep a separate count.
1160 (new_job): Check jobserver_tokens rather than children &&
1161 waiting_jobs. Increment jobserver_tokens when we get one.
1162 (free_child): If jobserver_tokens is 0, internal error. If it's
1163 >1, write a token back to the jobserver pipe (we don't write a
1164 token for the "free" job). Decrement jobserver_tokens.
1166 * main.c: Add variable master_job_slots.
1167 (main): Set it to hold the number of jobs requested if we're the
1168 master process, when using the jobserver.
1169 (die): Sanity checks: first test jobserver_tokens to make sure
1170 this process isn't holding any tokens we didn't write back.
1171 Second, if master_job_slots is set count the tokens left in the
1172 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1174 2005-04-24 Paul D. Smith <psmith@gnu.org>
1176 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1177 with -l# can lose jobserver tokens, because waiting jobs are not
1178 consulted properly when checking for the "free" token.
1180 * job.c (free_child): Count waiting_jobs as having tokens.
1181 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1182 handle jobs waiting for the load to drop.
1184 2005-04-23 Paul D. Smith <psmith@gnu.org>
1186 * main.c (main): Be careful to not core if a variable setting in
1187 the environment doesn't contain an '='. This is illegal but can
1188 happen in broken setups.
1189 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1191 2005-04-12 Paul D. Smith <psmith@gnu.org>
1193 The second expansion feature causes significant slowdown. Timing
1194 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1195 read the makefile before the feature, to 11+s to do the same
1196 operations after the feature. Additionally, memory usage
1197 increased drastically. To fix this I added some intelligence that
1198 avoids the overhead of the second expansion unless it's required.
1200 * dep.h: Add a new boolean field, need_2nd_expansion.
1202 * read.c (eval): When creating the struct dep for the target,
1203 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1204 (record_files): If there's a "%" in a static pattern rule, it gets
1205 converted to "$*" so set need_2nd_expansion to 1.
1207 * file.c (expand_deps): Rework to be more efficient. Only perform
1208 initialize_file_variables(), set_file_variables(), and
1209 variable_expand_for_file() if the need_2nd_expansion is set.
1211 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1212 (pattern_search): Ditto.
1213 * main.c (handle_non_switch_argument): Ditto.
1215 * read.c (read_all_makefiles): Ditto.
1216 (eval_makefile): Ditto.
1218 2005-04-07 Paul D. Smith <psmith@gnu.org>
1220 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1221 * variable.c (sync_Path_environment): Ditto.
1222 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1224 * main.c (main): Define the .FEATURES variable.
1225 * NEWS: Announce .FEATURES.
1226 * doc/make.texi (Special Variables): Document .FEATURES.
1228 * remake.c (check_dep): If a file is .PHONY, update it even if
1229 it's marked intermediate. Fixes Savannah bug #12331.
1231 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1233 * file.c (expand_deps): Factor out the second expansion and
1234 prerequisite line parsing logic from snap_deps().
1236 * file.c (snap_deps): Use expand_deps(). Expand and parse
1237 prerequisites of the .SUFFIXES special target first. Fixes
1238 Savannah bug #12320.
1240 2005-03-13 Paul D. Smith <psmith@gnu.org>
1242 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1245 2005-03-11 Paul D. Smith <psmith@gnu.org>
1247 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1248 available, not undefined (from Earnie Boyd).
1250 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1252 * implicit.c (pattern_search): Mark an intermediate target as
1253 precious if it happened to be a prerequisite of some (other)
1254 target. Fixes Savannah bug #12267.
1256 2005-03-09 Paul D. Smith <psmith@gnu.org>
1258 * read.c (eval_makefile): Add alloca(0).
1259 (eval_buffer): Ditto.
1261 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1263 * main.c (main): Use o_file instead of o_default when defining
1264 the .DEFAULT_TARGET special variable.
1265 * read.c (eval): Use define_variable_global() instead of
1266 define_variable() when setting new value for the .DEFAULT_TARGET
1267 special variable. Fixes Savannah bug #12266.
1269 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1271 * imlicit.c (pattern_search): Mark files for which an implicit
1272 rule has been found as targets. Fixes Savannah bug #12202.
1274 2005-03-04 Paul D. Smith <psmith@gnu.org>
1277 * doc/make.texi (Automatic Variables): Document $|.
1279 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1281 * read.c (record_files): Instead of substituting % with
1282 actual stem value in dependency list replace it with $*.
1283 This fixes stem triple expansion bug.
1285 * implicit.c (pattern_search): Copy stem to a separate
1286 buffer and make it a properly terminated string. Assign
1287 this buffer instead of STEM (which is not terminated) to
1288 f->stem. Instead of substituting % with actual stem value
1289 in dependency list replace it with $*. This fixes stem
1290 triple expansion bug.
1292 2005-03-01 Paul D. Smith <psmith@gnu.org>
1294 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1295 on Windows, as it takes a handle not a pid. Just exit.
1296 Fix from patch #3679, provided by Alessandro Vesely.
1298 * configure.in: Update check for sys_siglist[] from autoconf manual.
1299 * signame.c (strsignal): Update to use the new autoconf macro.
1301 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1303 * read.c (record_files): Add a check for the list of prerequisites
1304 of a static pattern rule being empty. Fixes Savannah bug #12180.
1306 2005-02-28 Paul D. Smith <psmith@gnu.org>
1308 * doc/make.texi (Text Functions): Update docs to allow the end
1309 ordinal for $(wordlist ...) to be 0.
1310 * function.c (func_wordlist): Fail if the start ordinal for
1311 $(wordlist ...) is <1. Matches documentation.
1312 Resolves Savannah support request #103195.
1314 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1315 previously we were stopping when !-q, exactly the opposite. This
1316 has been wrong since version 1.34, in 1994!
1317 (update_file): If we got an error don't break out to run more
1318 double-colon rules: just return immediately.
1319 Fixes Savannah bug #7144.
1321 2005-02-27 Paul D. Smith <psmith@gnu.org>
1323 * misc.c (end_of_token): Make argument const.
1324 * make.h: Update prototype.
1326 * function.c (abspath, func_realpath, func_abspath): Use
1327 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1328 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1329 * read.c (record_files): Ditto.
1330 * variable.c (do_variable_definition): Ditto.
1332 * function.c (func_error): Create a new function $(info ...) that
1333 simply prints the message to stdout with no extras.
1334 (function_table_init): Add new function to the table.
1335 * NEWS: Add $(info ...) reference.
1336 * doc/make.texi (Make Control Functions): Document it.
1338 New feature: if the system supports symbolic links, and the user
1339 provides the -L/--check-symlink-time flag, then use the latest
1340 mtime between the symlink(s) and the target file.
1342 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1343 readlink(). If both are available, define MAKE_SYMLINKS.
1344 * main.c: New variable: check_symlink_flag.
1345 (usage): Add a line for -L/--check-symlink-times to the help string.
1346 (switches): Add -L/--check-symlink-times command line argument.
1347 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1348 print a warning and disable it again.
1349 * make.h: Declare check_symlink_flag.
1350 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1351 if the file is a symlink then check each link in the chain and
1352 choose the NEWEST mtime we find as the mtime for the file. The
1353 newest mtime might be the file itself!
1354 * NEWS: Add information about this new feature.
1355 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1357 Avoid core dumps described in Savannah bug # 12124:
1359 * file.c: New variable snapped_deps remember whether we've run
1361 (snap_deps): Set it.
1362 * filedef.h: Extern it.
1363 * read.c (record_files): Check snapped_deps; if it's set then
1364 we're trying to eval a new target/prerequisite relationship from
1365 within a command script, which we don't support. Fatal.
1367 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1369 Implementation of the .DEFAULT_TARGET special variable.
1371 * read.c (eval): If necessary, update default_target_name when
1373 * read.c (record_files): Update default_target_file if
1374 default_target_name has changed.
1375 * main.c (default_target_name): Define.
1376 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1377 default_target_name is set use default_target_file as a root
1379 * filedef.h (default_target_name): Declare.
1380 * dep.h (free_dep_chain):
1381 * misc.c (free_dep_chain): Change to operate on struct nameseq
1382 and change name to free_ns_chain.
1383 * file.c (snap_deps): Update to use free_ns_chain.
1385 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1387 Implementation of the second expansion in explicit rules,
1388 static pattern rules and implicit rules.
1390 * read.c (eval): Refrain from chopping up rule's dependencies.
1391 Store them in a struct dep as a single dependency line. Remove
1392 the code that implements SySV-style automatic variables.
1394 * read.c (record_files): Adjust the code that handles static
1395 pattern rules to expand all percents instead of only the first
1396 one. Reverse the order in which dependencies are stored so that
1397 when the second expansion reverses them again they appear in
1398 the makefile order (with some exceptions, see comments in
1399 the code). Remove the code that implements SySV-style automatic
1402 * file.c (snap_deps): Implement the second expansion and chopping
1403 of dependency lines for explicit rules.
1405 * implicit.c (struct idep): Define an auxiliary data type to hold
1406 implicit rule's dependencies after stem substitution and
1409 * implicit.c (free_idep_chain): Implement.
1411 * implicit.c (get_next_word): Implement helper function for
1412 parsing implicit rule's dependency lines into words taking
1413 into account variable expansion requests. Used in the stem
1416 * implicit.c (pattern_search): Implement the second expansion
1417 for implicit rules. Also fixes bug #12091.
1419 * commands.h (set_file_variables): Declare.
1420 * commands.c (set_file_variables): Remove static specifier.
1422 * dep.h (free_dep_chain): Declare.
1423 * misc.c (free_dep_chain): Implement.
1425 * variable.h (variable_expand_for_file): Declare.
1426 * expand.c (variable_expand_for_file): Remove static specifier.
1428 * make.h (strip_whitespace): Declare.
1429 * function.c (strip_whitespace): Remove static specifier.
1431 2005-02-26 Paul D. Smith <psmith@gnu.org>
1433 * main.c (main): Check for ferror() when reading makefiles from stdin.
1434 Apparently some shells in Windows don't close pipes properly and
1437 2005-02-24 Jonathan Grant <jg@jguk.org>
1439 * configure.in: Add MinGW configuration options, and extra w32 code
1441 * Makefile.am: Add MinGW configuration options, and extra w32 code
1443 * main.c: Determine correct program string (after last \ without .exe).
1444 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1446 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1447 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1448 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1449 environment support.
1451 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1453 * function.c (func_shell): When initializing error_prefix, check
1454 that reading file name is not null. This fixes long-standing
1455 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1457 2005-02-09 Paul D. Smith <psmith@gnu.org>
1459 * maintMakefile: Update the CVS download URL to simplify them.
1460 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1461 downloading the .texi files from Savannah now.
1463 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1465 * main.c (handle_non_switch_argument): Only add variables to
1466 command_variables if they're not already there: duplicate settings
1467 waste space and can be confusing to read.
1469 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1470 this header is never included by non-WINDOWS32 code, and it
1471 requires <config.h> to define which isn't always included first.
1473 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1474 testing MINGW32 versions.
1476 * main.c (log_working_directory): flush stdout to be sure the WD
1477 change is printed before any stderr messages show up.
1479 2005-02-01 Paul D. Smith <psmith@gnu.org>
1481 * maintMakefile (po_repo): Update the GNU translation site URL.
1483 2004-12-01 Paul D. Smith <psmith@gnu.org>
1485 * main.c (main): Change char* env_shell to struct variable shell_var.
1486 * variable.c (target_environment): Use new shell_var.
1488 2004-11-30 Paul D. Smith <psmith@gnu.org>
1490 * configure.in: The old way we avoided creating build.sh from
1491 build.sh.in before build.sh.in exists doesn't work anymore; we
1492 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1493 the help!). This also keeps automake from complaining.
1494 * Makefile.am (README): Add a dummy target so automake won't
1495 complain that this file doesn't exist when we checkout from CVS.
1496 * maintMakefile (.dep_segment): Rewrite this rule since newer
1497 versions of automake don't provide DEP_FILES.
1499 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1501 Implementation of `realpath' and `abspath' built-in functions.
1503 * configure.in: Check for realpath.
1504 * function.c (abspath): Return an absolute file name that does
1505 not contain any `.' or `..' components, nor repeated `/'.
1506 * function.c (func_abspath): For each name call abspath.
1507 * function.c (func_realpath): For each name call realpath
1508 from libc or delegate to abspath if realpath is not available.
1509 * doc/make.texi (Functions for File Names): Document new functions.
1510 * doc/make.texi (Quick Reference): Ditto.
1512 2004-11-28 Paul D. Smith <psmith@gnu.org>
1514 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1515 arguments. Fixes bug #10252.
1517 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1519 * main.c (main): Set SHELL to v_noexport by default. Remember the
1520 original environment setting of SHELL in the env_shell variable.
1521 * main.h: Export new env_shell variable.
1522 * variable.c (target_environment): If we find a v_noexport
1523 variable for SHELL, add a SHELL variable with the env_shell value.
1524 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1525 * doc/make.texi (Variables/Recursion): Ditto.
1527 2004-11-28 Paul D. Smith <psmith@gnu.org>
1529 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1530 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1531 Patch by Alessandro Vesely.
1533 2004-11-12 Paul D. Smith <psmith@gnu.org>
1535 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1536 the command line if it's inside a string.
1537 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1539 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1541 * function.c (func_lastword): New function: return last word
1542 from the list of words.
1543 * doc/make.texi: Document $(lastword ). Fix broken links in
1544 Quick Reference section.
1546 2004-10-06 Paul D. Smith <psmith@gnu.org>
1548 Apply patch from Alessandro Vesely, provided with bug # 9748.
1549 Fix use of tmpnam() to work with Borland C.
1551 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1552 construction of a temporary filename, and call new function
1553 create_batch_filename().
1554 (create_batch_filename) [WINDOWS32]: New function to create a
1557 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1559 * read.c (record_target_var): Expand simple pattern-specific
1561 * variable.c (initialize_file_variables): Do not expand simple
1562 pattern-specific variable.
1564 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1566 * remake.c (update_file_1): When rebuilding makefiles inherit
1567 dontcare flag from a target that triggered update.
1569 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1571 * variable.c (initialize_file_variables): Mark pattern-specific
1572 variable as a per-target and copy export status.
1574 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1576 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1578 * implicit.c (pattern_search): When considering an implicit rule's
1579 prerequisite check that it is actually a target rather then
1580 just an entry in the file hashtable.
1582 2004-09-21 Paul D. Smith <psmith@gnu.org>
1584 * read.c (readstring): Fix some logic errors in backslash handling.
1585 (eval): Remove some unnecessary processing in buffer handling.
1586 (record_target_var): Assert that parse_variable_definition() succeeded.
1587 Reported by: Markus Mauhart <qwe123@chello.at>.
1589 * misc.c: Removed the sindex() function. All instances of this
1590 function were trivially replaceable by the standard strstr()
1591 function, and that function will always have better (or certainly
1592 no worse) performance than the very simple-minded algorithm
1593 sindex() used. This can matter with complex makefiles.
1594 * make.h: Remove the prototype for sindex().
1595 * function.c (subst_expand): Convert sindex() call to strstr().
1596 This means we no longer need to track the TLEN value so remove that.
1597 (func_findstring): Convert sindex() to strstr().
1598 * commands.c (chop_commands): Convert sindex() calls to strstr().
1599 Suggested by: Markus Mauhart <qwe123@chello.at>.
1601 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1602 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1603 If SHELL is set to CMD.EXE then assume it's batch-mode and
1604 non-unixy. I wrote the code differently from the patch, though,
1605 to make it safer. This also resolves bug #9174.
1607 2004-09-20 Paul D. Smith <psmith@gnu.org>
1609 * expand.c (variable_expand_string): Modify to invoke
1610 patsubst_expand() instead of subst_expand(); the latter didn't
1611 handle suffix patterns correctly.
1612 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1613 was used only from variable_expand_string() and is no longer used
1615 (func_subst): Ditto, on call to subst_expand().
1616 (patsubst_expand): Require the percent pointers to point to the
1617 character after the %, not to the % itself.
1618 * read.c (record_files): New call criteria for patsubst_expand().
1619 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1620 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1622 2004-09-19 Paul D. Smith <psmith@gnu.org>
1624 * function.c (subst_expand): Fix a check in by_word: look for a
1625 previous blank if we're beyond the beginning of the string, not
1626 the beginning of the word.
1627 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1629 2004-05-16 Paul D. Smith <psmith@gnu.org>
1631 * remake.c (update_goal_chain): Change the argument specifying
1632 whether we're rebuilding makefiles to be a global variable,
1633 REBUILDING_MAKEFILES.
1634 (complain): Extract the code that complains about no rules to make
1635 a target into a separate function.
1636 (update_file_1): If we tried to rebuild a file during the makefile
1637 rebuild phase and it was dontcare, then no message was printed.
1638 If we then try to build the same file during the normal build,
1639 print a message this time.
1640 (remake_file): Don't complain about un-remake-able files when
1641 we're rebuilding makefiles.
1643 2004-05-11 Paul D. Smith <psmith@gnu.org>
1645 * job.c (construct_command_argv_internal): OS/2 patches from
1646 Andreas Buening <andreas.buening@nexgo.de>.
1648 2004-05-10 Paul D. Smith <psmith@gnu.org>
1650 * remake.c (update_file): Don't walk the double-colon chain unless
1651 this is a double-colon rule. Fix suggested by Boris Kolpackov
1652 <boris@kolpackov.net>.
1654 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1655 * readme.vms: New section describing OpenVMS support and issues.
1656 * default.c (default_variables): Add support for IA64.
1657 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1658 without some privilege aborts make with the error
1659 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1660 pressing Ctrl+Y and the input device is no terminal. The change
1661 catches this error and just continues.
1663 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1665 2004-04-25 Paul D. Smith <psmith@gnu.org>
1667 * commands.c (set_file_variables): Set $< properly in the face of
1668 order-only prerequisites.
1669 Patch from Boris Kolpackov <boris@kolpackov.net>
1671 2004-04-21 Bob Byrnes <byrnes@curl.com>
1673 * main.c (main): Notice failures to remake makefiles.
1675 2004-03-28 Paul D. Smith <psmith@gnu.org>
1677 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1679 * job.c: No default shell for RISC OS.
1680 (load_too_high): Hard-code the return to 1.
1681 (construct_command_argv_internal): No sh_chars or sh_cmds.
1682 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1684 2004-03-20 Paul D. Smith <psmith@gnu.org>
1686 * variable.c (do_variable_definition): Don't append from the
1687 global set if a previous non-appending target-specific variable
1688 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1691 * expand.c (reference_variable): Don't give up on variables with
1692 no value that have the target-specific append flag set: they might
1693 have a value after all. Reported by Oliver Schmidt
1694 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1695 <nikulin@dx1cmd.inp.nsk.su>.
1697 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1698 refer to absolute pathnames in directories that don't exist: some
1699 portion of the makefile could create those directories before we
1700 match the pattern. Fixes bugs #775 and #108.
1702 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1704 * main.c (main): Free makefile_mtimes if we have any.
1705 * README.W32.template: Update documentation for the current status
1706 of the MS-Windows port.
1707 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1708 environment variable is sometimes already defined which causes the
1710 * main.c (debug_signal_handler): Only define this function if
1711 SIGUSR1 is available.
1713 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1715 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1716 * README.OS2.template: Documentation updates.
1717 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1718 link line for safety.
1719 * maintMakefile (build.sh.in): Remove an extraneous ")".
1720 * job.c (child_execute_job): Close saved FDs.
1721 * job.c (exec_command) [OS/2]: exec_command(): If the command
1722 can't be exec'ed and if the shell is not Unix-sh, then try again
1723 with argv = { "cmd", "/c", ... }. Normally, this code is never
1724 reached for the cmd shell unless the command really doesn't exist.
1725 (construct_command_argv_internal) [OS/2]: The code for cmd
1726 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1727 The CMD builtin commands are case insensitive so use strcasecmp().
1729 2004-03-19 Paul D. Smith <psmith@gnu.org>
1731 * read.c (do_define): Re-order line counter increment so the count
1732 is accurate (we were losing one line per define). Reported by
1733 Dave Yost <Dave@Yost.com>.
1735 2004-03-06 Paul D. Smith <psmith@gnu.org>
1737 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1739 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1740 * misc.c (message,error,fatal): Ditto.
1741 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1742 * config.h.W32.template: Ditto.
1743 * config.h-vms.template: Ditto.
1744 * config.ami.template: Ditto.
1746 2004-03-04 Paul D. Smith <psmith@gnu.org>
1748 * README.template: Add a note about broken /bin/sh on SunOS
1749 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1751 * misc.c (message, error, fatal): Don't use "..." if we're using
1752 varargs. ansi2knr should handle this but it doesn't work: it
1753 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1754 done. On many systems (SunOS for example) va_dcl is a #define.
1755 So, force the use of the non-"..." version on pre-ANSI compilers.
1757 * maintMakefile (sign-dist): Create some rules to help automate
1758 the new GNU ftp upload method.
1760 2004-02-24 Paul D. Smith <psmith@gnu.org>
1762 * config.h.W32.template: Add HAVE_STDARG_H
1763 * config.h-vms.template: Ditto.
1764 * config.ami.template: Ditto.
1766 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1768 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1769 * build_w32.bat: Remove extra "+".
1771 2004-02-23 Paul D. Smith <psmith@gnu.org>
1773 * make.h: Create an UNUSED macro to mark unused parameters.
1774 * (many): Clean up warnings by applying UNUSED, fixing
1775 signed/unsigned incompatibilities, etc.
1777 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1779 * filedef.h: Name the command_state enumeration.
1780 * file.c (set_command_state): Use the enumeration in the function
1783 * configure.in: Explicitly set SET_MAKE to empty, to disable
1784 MAKE=make even when no make already exists. Fix bug #3823.
1786 2004-02-22 Paul D. Smith <psmith@gnu.org>
1788 * maintMakefile: Perl script to clean up all non-CVS files. Use
1789 it on all the subdirectories for the cvs-clean target.
1791 * main.c (decode_switches): Require non-empty strings for all our
1792 string command-line options. Fixes Debian bug # 164165.
1794 * configure.in: Check for stdarg.h and varargs.h.
1795 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1796 for printing messages.
1797 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1802 A number of patches for OS/2 support from Andreas Buening
1803 <andreas.buening@nexgo.de>:
1805 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1806 disable the SIGCHLD handler.
1807 (reap_children) [OS/2]: Remove special handling of job_rfd.
1808 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1809 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1810 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1811 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1812 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1815 2004-02-21 Paul D. Smith <psmith@gnu.org>
1817 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1818 <mail@kristov.de> reports that if process_begin() fails we don't
1819 handle the error condition correctly in all cases.
1820 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1821 to have a newline on the message.
1823 * job.c (construct_command_argv_internal): Add "test" to UNIX
1824 sh_cmds[]. Fixes Savannah bug # 7606.
1826 2004-02-04 Paul D. Smith <psmith@gnu.org>
1828 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1829 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1830 Hartmut Becker <Hartmut.Becker@hp.com>.
1832 2004-01-21 Paul D. Smith <psmith@gnu.org>
1834 * job.c (load_too_high): Implement an algorithm to control the
1835 "thundering herd" problem when using -l to control job creation
1836 via the load average. The system only recomputes the load once a
1837 second but we can start many jobs in a second. To solve this we
1838 keep track of the number of jobs started in the last second and
1839 apply a weight to try to guess what a correct load would be.
1840 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1841 Also fixes bug #4693.
1842 (reap_children): Decrease the job count for this second.
1843 (start_job_command): Increase the job count for this second.
1845 * read.c (conditional_line): Expand the text after ifn?def before
1846 checking to see if it's a single word. Fixes bug #7257.
1848 2004-01-09 Paul D. Smith <psmith@gnu.org>
1850 * file.c (print_file): Recurse to print all targets in
1851 double-colon rules. Fixes bug #4518, reported (with patch) by
1852 Andrew Chatham <chatham@google.com>.
1854 2004-01-07 Paul D. Smith <psmith@gnu.org>
1856 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1857 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1858 AC_FUNC_SETVBUF_REVERSED.
1860 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1861 (MAKE Variable): Fix Savannah bug #4898.
1863 * job.c (construct_command_argv_internal): Add "!" to the list of
1864 shell escape chars. POSIX sh allows it to appear before a
1865 command, to negate the exit code. Fixes bug #6404.
1867 * implicit.c (pattern_search): When matching an implicit rule,
1868 remember which dependencies have the ignore_mtime flag set.
1869 Original fix provided in Savannah patch #2349, by Benoit
1870 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1872 2003-11-22 Paul D. Smith <psmith@gnu.org>
1874 * README.W32.template (Outputs): Clarification on -j with
1875 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1878 2003-11-02 Paul D. Smith <psmith@gnu.org>
1880 * function.c (func_if): Strip all the trailing whitespace from the
1881 condition, then don't expand it. Fixed bug # 5798.
1883 * expand.c (recursively_expand_for_file): If we're expanding a
1884 variable with no file context, then use the variable's context.
1887 2003-10-21 Paul D. Smith <psmith@gnu.org>
1889 * main.c (log_working_directory): Add newlines to printf()s.
1891 * README.cvs: Add a note to ignore warnings during autoreconf.
1893 * maintMakefile (po_repo): Set a new URL for PO file updates.
1894 (get-config/config.guess get-config/config.sub): Get these files
1895 from the Savannah config project instead of ftp.gnu.org.
1897 2003-10-05 Paul Eggert <eggert@twinsun.com>
1899 * main.c (main): Avoid potential subscript error if environ has
1902 2003-08-22 Paul D. Smith <psmith@gnu.org>
1904 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1905 systems which don't yet implement the C89 standard :-/.
1907 2003-07-18 Paul D. Smith <psmith@gnu.org>
1909 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1910 [WINDOWS32]: Initialize hash.
1912 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1914 * dir.c (read_dirstream): Provide a workaround for broken versions of
1915 the MinGW dirent structure.
1917 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1919 * w32/include/dirent.h: Add __MINGW32__ filter.
1921 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1923 * make.h: Add global declaration of *make_host.
1924 * main.c (print_usage): Remove local declaration of *make_host.
1925 (print_version): Display "This program built for ..." after Copyright
1928 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1930 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1931 execution of "makeinfo --html make.texi".
1933 2003-04-30 Paul D. Smith <psmith@gnu.org>
1935 * build.template: Make some changes to maybe allow this script to
1936 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1938 * README.OS2.template: New file for OS/2 support. Original
1939 contributed by Andreas Buening.
1940 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1943 2003-04-19 Paul D. Smith <psmith@gnu.org>
1945 Fix bug #1405: allow a target to match multiple pattern-specific
1948 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1949 variable.c, where they've always belonged.
1950 * rule.h: Move the prototypes and struct pattern_var as well.
1951 * variable.c (initialize_file_variables): Invoke
1952 lookup_pattern_var() in a loop, until no more matches are found.
1953 If a match is found, create a new variable set for the target's
1954 pattern variables. Then merge the contents of each matching
1955 pattern variable set into the target's pattern variable set.
1956 (lookup_pattern_var): Change this function to be usable
1957 in a loop. It takes a starting position: if NULL, start at the
1958 beginning; if non-NULL, start with the pattern variable after that
1959 position, and return the next matching pattern.
1960 (create_pattern_var): Create a unique instance of
1961 pattern-specific variables for every definition in the makefile.
1962 Don't combine the same pattern together. This allows us to
1963 process the variable handling properly even when the same pattern
1964 is used multiple times.
1965 (parse_variable_definition): New function: break out the parsing
1966 of a variable definition line from try_variable_definition.
1967 (try_variable_definition): Call parse_variable_definition to
1969 (print_variable_data_base): Print out pattern-specific variables.
1970 * variable.h (struct variable): Remember when a variable is
1971 conditional. Also remember its flavor.
1972 (struct pattern_var): Instead of keeping a variable set, we just
1973 keep a single variable for each pattern.
1974 * read.c (record_target_var): Each pattern variable contains only a
1975 single variable, not a set, so create it properly.
1976 * doc/make.texi (Pattern-specific): Document the new behavior.
1978 2003-04-17 Paul D. Smith <psmith@gnu.org>
1980 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1981 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1982 file/directory naming rules for VMS so I can't tell whether this
1985 2003-04-09 Paul D. Smith <psmith@gnu.org>
1987 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1988 DOS-style pathnames: backslash separators and drive specifiers.
1990 2003-03-28 Paul D. Smith <psmith@gnu.org>
1992 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1993 the intermediate flag on all targets. Fixes bug #2515.
1995 2003-03-24 Paul D. Smith <psmith@gnu.org>
1997 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1998 Upgrade to autoconf 2.57 and automake 1.7.3.
2000 * job.c: More OS/2 changes from Andreas Buening.
2002 * file.c (print_file): Fix variable initialization.
2005 * remake.c (notice_finished_file):
2007 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2008 some calls (like readdir()) return NULL in valid situations
2009 without resetting errno. Fixes bug #2846.
2011 2003-02-25 Paul D. Smith <psmith@gnu.org>
2013 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2015 * job.c (_is_unixy_shell) [OS/2]: New function.
2016 Set default shell to /bin/sh.
2017 (reap_children): Close the job_rfd pipe here since we don't use a
2019 (set_child_handler_action_flags): define this to empty on OS/2.
2020 (start_job_command): Close the jobserver pipe and use
2021 child_execute_job() instead of fork/exec.
2022 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2023 rather than exec'ing, then reconfigure stdin/stdout.
2024 (exec_command): Rewrite to use spawn instead of exec. Return the
2027 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2028 in DOS. Handle the TEMP environment variable as in DOS. Don't
2029 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2030 use -j in DOS mode. Use child_execute_job() instead of
2033 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2036 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2037 prototypes that return values.
2039 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2041 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2042 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2044 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2047 2003-02-24 Paul D. Smith <psmith@gnu.org>
2049 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2050 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2051 (child_execute_job) [VMS]: Handle error status properly.
2052 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2054 * function.c (func_shell): Use EINTRLOOP() while reading from the
2055 subshell pipe (Fixes bug #2502).
2056 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2058 * main.c (main): Ditto.
2060 2003-01-30 Paul D. Smith <psmith@gnu.org>
2062 * read.c (eval): eval() was not fully reentrant, because the
2063 collapsed buffer was static. Change it to be an automatic
2064 variable so that eval() can be invoked recursively.
2066 (eval): Apply patch # 1022: fix memory reference error on long
2067 target-specific variable lines.
2068 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2070 * function.c (check_numeric): Combine the is_numeric() function
2071 into this function, since it's only called from one place.
2072 Constify this function. Have it print the incorrect string in the
2073 error message. Fixes bug #2407.
2074 (strip_whitespace): Constify.
2075 (func_if): Constify.
2076 * expand.c (expand_argument): Constify.
2078 2003-01-29 Paul D. Smith <psmith@gnu.org>
2080 Fix bug # 2169, also reported by other people on various systems.
2082 * make.h: Some systems, such as Solaris and PTX, do not fully
2083 implement POSIX-compliant SA_RESTART functionality; important
2084 system calls like stat() and readdir() can still fail with EINTR
2085 even if SA_RESTART has been set on the signal handler. So,
2086 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2087 EINTR for system calls which return -1 or 0 (NULL), respectively,
2089 Also, remove the old atomic_stat()/atomic_readdir() and
2090 HAVE_BROKEN_RESTART handling.
2092 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2094 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2095 * remake.c (touch_file): Ditto.
2097 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2098 * read.c (construct_include_path): Ditto.
2099 * remake.c (name_mtime): Ditto.
2100 * vpath.c (selective_vpath_search): Ditto.
2101 * dir.c (find_directory): Ditto.
2102 (local_stat): Ditto.
2103 (find_directory): Use ENULLLOOP() to wrap opendir().
2104 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2106 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2107 atomic_readdir() handling.
2109 2003-01-22 Paul D. Smith <psmith@gnu.org>
2111 * function.c (func_call): Fix Bug #1744. If we're inside a
2112 recursive invocation of $(call ...), mask any of the outer
2113 invocation's arguments that aren't used by this one, so that this
2114 invocation doesn't "inherit" them accidentally.
2116 2002-12-05 Paul D. Smith <psmith@gnu.org>
2118 * function.c (subst_expand): Valery Khamenia reported a
2119 pathological performance hit when doing substitutions on very
2120 large values with lots of words: turns out we were invoking
2121 strlen() a ridiculous number of times. Instead of having each
2122 call to sindex() call strlen() again, keep track of how much of
2123 the text we've seen and pass the length to sindex().
2125 2002-11-19 Paul D. Smith <psmith@gnu.org>
2127 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2130 2002-11-16 Paul D. Smith <psmith@gnu.org>
2132 * NMakefile.template (OBJS): Add hash.c object file.
2133 * SMakefile.template (srcs): Ditto.
2134 * Makefile.ami (objs): Ditto.
2135 * build_w32.bat: Ditto.
2137 * Makefile.DOS.template: Remove extra dependencies.
2139 2002-10-25 Paul D. Smith <psmith@gnu.org>
2141 * expand.c (install_variable_buffer): New function. Install a new
2142 variable_buffer context and return the previous one.
2143 (restore_variable_buffer): New function. Free the current
2144 variable_buffer context and put a previously saved one back.
2145 * variable.h: Prototypes for {install,restore}_variable_buffer.
2146 * function.c (func_eval): Push a new variable_buffer context
2147 before we eval, then restore the old one when we're done.
2150 * read.c (install_conditionals): New function. Install a new
2151 conditional context and return the previous one.
2152 (restore_conditionals): New function. Free the current
2153 conditional context and put a previously saved one back.
2154 (eval): Use the {install,restore}_conditionals for "include"
2156 (eval_buffer): Use {install,restore}_conditionals to preserve the
2157 present conditional state before we evaluate the buffer.
2160 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2162 (Recursion): Add a variable index entry for CURDIR.
2164 * README.cvs: Update to appropriate versions.
2165 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2166 don't need to copy loadavg.c: automake is smart enough to create
2167 it for me. Still have a bug in automake related to ansi2knr tho.
2169 2002-10-14 Paul D. Smith <psmith@gnu.org>
2171 * remake.c (notice_finished_file): Only touch targets if they have
2172 at least one command (as per POSIX). Resolve Bug #1418.
2174 * *.c: Convert to using ANSI C-style function definitions.
2175 * Makefile.am: Enable the ansi2knr feature of automake.
2176 * configure.in: ditto.
2178 2002-10-13 Paul D. Smith <psmith@gnu.org>
2180 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2181 for automatic variable values like $^, etc. In the case of very
2182 large lists of prerequisites this causes problems. Instead reuse
2183 a static buffer (resizeable) for each variable.
2185 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2186 target-specific variable definitions. Check for it and set an
2188 (record_target_var): Set the export field to v_export if the
2189 "exported" flag is set.
2190 * doc/make.texi (Target-specific): Document the ability to use
2193 * doc/make.texi: Change the name of the section on automatic
2194 variables from "Automatic" to "Automatic Variables". Added text
2195 clarifying the scope of automatic variables.
2197 2002-10-04 Paul D. Smith <psmith@gnu.org>
2199 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2201 (record_files): Ditto.
2203 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2204 the search for the '=' to only within the enclosing parens.
2206 2002-10-03 Paul D. Smith <psmith@gnu.org>
2208 Version 3.80 released.
2210 * dir.c: Change hash functions to use K&R function definition style.
2211 * function.c: Ditto.
2213 * variable.c: Ditto.
2215 Update to automake 1.7.
2217 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2218 (pdf): Remove this target as automake now provides one.
2220 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2222 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2224 * makefile.com: Updates for GNU make 3.80.
2225 * makefile.vms: Ditto.
2227 2002-09-23 Paul D. Smith <psmith@gnu.org>
2229 * read.c (enum make_word_type): Remove w_comment.
2230 (get_next_mword): Don't treat comment characters as special; where
2231 this function is used we will never see a comment (it's stripped
2232 before we get here) and treating comments specially means that
2233 targets like "foo\#bar" aren't handled properly.
2235 2002-09-18 Paul D. Smith <psmith@gnu.org>
2237 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2239 * read.c (eval): Expansion of arguments to export/unexport was
2240 ignoring all arguments after the first one. Change the algorithm
2241 to expand the whole line once, then parse the results.
2243 2002-09-17 Paul D. Smith <psmith@gnu.org>
2245 Fix Bug #940 (plus another bug I found while looking at this):
2247 * read.c (record_target_var): enter_file() will add a new entry if
2248 it's a double-colon target: we don't want to do that in this
2249 situation. Invoke lookup_file() and only enter_file() if it does
2250 not already exist. If the file we get back is a double-colon then
2251 add this variable to the "root" double-colon target.
2253 * variable.c (initialize_file_variables): If this file is a
2254 double-colon target but is not the "root" target, then initialize
2255 the root and make the root's variable list the parent of our
2258 2002-09-13 Paul D. Smith <psmith@gnu.org>
2260 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2262 * hash.c (round_up_2): Get rid of a warning.
2264 2002-09-12 Paul D. Smith <psmith@gnu.org>
2266 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2267 so it doesn't complain about getloadavg.c.
2269 * commands.c (set_file_variables): Make sure we always alloca() at
2270 least 1 character for the value of $? (for '\0').
2272 2002-09-11 Paul D. Smith <psmith@gnu.org>
2274 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2275 macro to use RESULT instead of the incorrect _RESULT_.
2277 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2278 and atomic_readdir(). We need to #include dirent.h to get this to
2280 * misc.c (atomic_readdir): Fix typos.
2282 2002-09-10 Paul D. Smith <psmith@gnu.org>
2284 * read.c (eval): Expand variable lists given to export and
2285 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2286 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2288 * doc/make.texi (Variables/Recursion): Document this.
2289 (Conditional Syntax): And here.
2291 2002-09-09 Paul D. Smith <psmith@gnu.org>
2293 * configure.in: Check for memmove().
2295 2002-09-07 Paul D. Smith <psmith@gnu.org>
2297 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2298 Michael Sterrett <msterret@coat.com> reports that while it has
2299 SA_RESTART, it does not work properly.
2301 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2302 that invokes stat() and loops to do it again if it returns EINTR.
2303 (atomic_readdir): Ditto, with readdir().
2305 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2306 and readdir() to atomic_stat() and atomic_readdir().
2308 2002-09-04 Paul D. Smith <psmith@gnu.org>
2310 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2311 reports that GNU make sometimes doesn't recognize that targets can
2312 be made, when directories can be created as prerequisites. He
2313 reports that changing the order of predicates in the DEP->changed
2314 flag test so that lookup_file() is always performed, solves this
2317 2002-08-08 Paul D. Smith <psmith@gnu.org>
2319 * configure.in: Require a newer version of gettext.
2321 * misc.c (perror_with_name): Translate the format string (for
2322 right-to-left language support).
2323 (pfatal_with_name): Ditto.
2325 * main.c: Create a static array of strings to store the usage
2326 text. This is done to facilitate translations.
2327 (struct command_switch): Remove argdesc and description fields.
2328 (switches): Remove values for obsolete fields.
2329 (print_usage): Print each element of the usage array.
2331 * hash.c: Change function definitions to be K&R style.
2333 2002-08-02 Paul D. Smith <psmith@gnu.org>
2335 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2336 this one because it's too hard to get right. We'll look at it for
2338 * main.c (main): Don't create the .TARGETS variable.
2339 * variable.c (handle_special_var): Don't handle .TARGETS.
2341 2002-08-01 Paul D. Smith <psmith@gnu.org>
2343 * main.c (switches): Add a new option, -B (--always-make). If
2344 specified, make will rebuild all targets that it encounters even
2345 if they don't appear to be out of date.
2346 (always_make_flag): New flag.
2347 * make.h: Extern always_make_flag.
2348 * remake.c (update_file_1): Check always_make_flag; if it's set we
2349 will always rebuild any target we can, even if none of its
2350 prerequisites are newer.
2353 * doc/make.texi (Shell Function): Make it clear that make
2354 variables marked as "export" are not passed to instances of the
2357 Add new introspection variable .VARIABLES and .TARGETS.
2359 * variable.c (handle_special_var): New function. If the variable
2360 reference passed in is "special" (.VARIABLES or .TARGETS),
2361 calculate the new value if necessary. .VARIABLES is handled here:
2362 walk through the hash of defined variables and construct a value
2363 which is a list of the names. .TARGETS is handled by
2364 build_target_list().
2365 (lookup_variable): Invoke handle_special_var().
2366 * file.c (build_target_list): Walk through the hask of known files
2367 and construct a list of the names of all the ones marked as
2369 * main.c (main): Initialize them to empty (and as simple variables).
2370 * doc/make.texi (Special Variables): Document them.
2371 * NEWS: Mention them.
2373 * variable.h (struct variable): Add a new flag "exportable" which
2374 is true if the variable name is valid for export.
2375 * variable.c (define_variable_in_set): Set "exportable" when a new
2376 variable is defined.
2377 (target_environment): Use the "exportable" flag instead of
2378 re-checking the name here... an efficiency improvement.
2380 2002-07-31 Paul D. Smith <psmith@gnu.org>
2382 * config.h-vms.template: Updates to build on VMS. Thanks to
2383 Brian_Benning@aksteel.com for helping verify the build.
2384 * makefile.com: Build the new hash.c file.
2385 * hash.h: Use strcpmi(), not stricmp(), in the
2386 HAVE_CASE_INSENSITIVE_FS case.
2388 2002-07-30 Paul D. Smith <psmith@gnu.org>
2390 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2391 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2392 Reported by <Brian_Benning@aksteel.com>.
2394 2002-07-10 Paul D. Smith <psmith@gnu.org>
2396 * variable.c (pop_variable_scope): Remove variable made unused by
2397 new hash infrastructure.
2398 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2399 comparisons as well as name comparisons.
2400 * variable.h: Add a prototype for new hash_init_function_table().
2401 * file.c (lookup_file): Remove variables made unused by new hash
2403 * dir.c (directory_contents_hash_2): Missing return of hash value.
2404 (dir_contents_file_exists_p): Remove variables made unused by new
2405 hash infrastructure.
2408 Installed Greg McGary's integration of the hash functions from the
2409 GNU id-utils package:
2411 2002-07-10 Greg McGary <greg@mcgary.org>
2413 * scripts/functions/filter-out: Add literals to to the
2414 pattern space in order to add complexity, and trigger
2415 use of an internal hash table. Fix documentation strings.
2416 * scripts/targets/INTERMEDIATE: Reverse order of files
2417 passed to expected `rm' command.
2419 2002-07-10 Greg McGary <greg@mcgary.org>

2496 variable_hash_cmp): New functions.

2511 2002-07-10 Paul D. Smith <psmith@gnu.org>
2513 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2514 prerequisite list. A real SysV make will expand the entire
2515 prerequisites list _twice_: we don't do that as it's a big
2516 backward-compatibility problem. We only replace those specific
2519 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2520 references left in the list of prerequisites. Check for .POSIX as
2521 we record targets, so we can disable non-POSIX behavior while
2522 reading makefiles as well as running them.
2523 (eval): Check the prerequisite list to see if we have anything
2524 that looks like a SysV prerequisite variable reference.
2526 2002-07-09 Paul D. Smith <psmith@gnu.org>
2528 * doc/make.texi (Prerequisite Types): Add a new section describing
2529 order-only prerequisites.
2531 * read.c (uniquize_deps): If we have the same file as both a
2532 normal and order-only prereq, get rid of the order-only prereq,
2533 since the normal one supersedes it.
2535 2002-07-08 Paul D. Smith <psmith@gnu.org>
2537 * AUTHORS: Added Greg McGary to the AUTHORS file.
2538 * NEWS: Blurbed order-only prerequisites.
2539 * file.c (print_file): Show order-only deps properly when printing
2542 * maintMakefile: Add "update" targets for wget'ing the latest
2543 versions of various external files. Taken from Makefile.maint in
2546 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2547 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2549 2002-07-07 Paul D. Smith <psmith@gnu.org>
2551 * po/*.po: Remove. We'll use wget to retrieve them at release
2554 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2555 rather than a shell you get an exception. Make sure we look up
2556 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2558 * remake.c (notice_finished_file): Fix handling of -t flag.
2559 Patch provided by Henning Makholm <henning@makholm.net>.
2561 * implicit.c (pattern_search): Some systems apparently run short
2562 of stack space, and using alloca() in this function caused an
2563 overrun. I modified it to use xmalloc() on the two variables
2564 which seemed like they might get large. Fixes Bug #476.
2566 * main.c (print_version): Update copyright notice to conform with
2568 (print_usage): Update help output.
2570 * function.c (func_eval): Create a new make function, $(eval
2571 ...). Expand the arguments, put them into a buffer, then invoke
2572 eval_buffer() on the resulting string.
2573 (func_quote): Create a new function, $(quote VARNAME). Inserts
2574 the value of the variable VARNAME without expanding it any
2577 * read.c (struct ebuffer): Change the linebuffer structure to an
2578 "eval buffer", which can be either a file or a buffer.
2579 (eval_makefile): Move the code in the old read_makefile() which
2580 located a makefile into here: create a struct ebuffer with that
2581 information. Have it invoke the new function eval() with that
2583 (eval_buffer): Create a new function that creates a struct ebuffer
2584 that holds a string buffer instead of a file. Have it invoke
2585 eval() with that ebuffer.
2586 (eval): New function that contains the guts of the old
2587 read_makefile() function: this function parses makefiles. Obtains
2588 data to parse from the provided ebuffer. Some modifications to
2589 make the flow of the function cleaner and clearer. Still could
2590 use some work here...
2591 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2592 contents of the define/endef variable from the ebuffer.
2593 (readstring): Read the next line from a string-style ebuffer.
2594 (readline): Read the next line from an ebuffer. If it's a string
2595 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2598 * dep.h (eval_buffer): Prototype eval_buffer();
2600 * variable.c (do_variable_definition): Make sure that all
2601 non-target-specific variables are registered in the global set.
2602 If we're invoked from an $(eval ...) we might be inside a $(call
2603 ...) or other function which has pushed a variable scope; we still
2604 want to define our variables from evaluated makefile code in the
2607 2002-07-03 Greg McGary <greg@mcgary.org>
2609 * dep.h (struct dep) [ignore_mtime]: New member.
2610 [changed]: convert to a bitfield.
2611 * implicit.c (pattern_search): Zero ignore_mtime.
2612 * main.c (main, handle_non_switch_argument): Likewise.
2613 * rule.c (convert_suffix_rule): Likewise.
2614 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2615 (read_makefile): Parse '|' in prerequisite list.
2616 (uniquize_deps): Consider ignore_mtime when comparing deps.
2617 * remake.c (update_file_1, check_dep): Don't force remake for
2618 dependencies that have d->ignore_mtime.
2619 * commands.c (FILE_LIST_SEPARATOR): New constant.
2620 (set_file_variables): Don't include a
2621 prerequisite in $+, $^ or $? if d->ignore_mtime.
2624 2002-06-18 Paul D. Smith <psmith@gnu.org>
2626 * make.texinfo: Updates for next revision. New date/rev/etc.
2627 Recreate all Info menus. Change license on the manual to the GNU
2628 Free Documentation License. A number of typos.
2629 (Variables Simplify): Don't use "-" before it's defined.
2630 (Automatic Prerequisites): Rewrite the target example to work
2631 properly if the compile fails. Remove incorrect comments about
2632 how "set -e" behaves.
2633 (Text Functions): Move the "word", "wordlist", "words", and
2634 "firstword" functions here, from "File Name Functions".
2635 * make-stds.texi: Update from latest GNU version.
2636 * fdl.texi: (created) Import the latest GNU version.
2638 2002-06-06 Paul D. Smith <psmith@gnu.org>
2640 * variable.c (do_variable_definition): New function: extract the
2641 part of try_variable_definition() that actually sets the value
2642 into a separate function.
2643 (try_variable_definition): Call do_variable_definition() after
2644 parsing the variable definition string.
2645 (define_variable_in_set): Make the name argument const.
2647 * variable.h (enum variable_flavor): Make public.
2648 (do_variable_definition): Create prototype.
2650 * read.c (read_all_makefiles): Create a new built-in variable,
2652 (read_makefile): Add each makefile read in to this variable value.
2654 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2656 * Makefile.DOS.template: Tweak according to changes in the
2657 distribution. Add back the dependencies of *.o files.
2659 * configh.dos.template: Synchronize with config.h.in.
2661 2002-05-09 Paul D. Smith <psmith@gnu.org>
2663 * file.c (file_timestamp_now): Use K&R function declaration.
2665 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2666 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2667 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2668 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2669 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2670 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2671 nlist.n_name is a pointer rather than an array.
2673 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2674 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2675 * configure.in: Use it instead of the old version.
2677 * main.c (main): Prefer setvbuf() to setlinebuf().
2679 2002-05-08 Paul D. Smith <psmith@gnu.org>
2681 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2682 (loadavg_LDADD): Ditto.
2684 2002-04-29 Paul D. Smith <psmith@gnu.org>
2686 * expand.c (recursively_expand_for_file): Rename
2687 recursively_expand() to recursively_expand_for_file() and provide
2688 an extra argument, struct file. If the argument is provided, set
2689 the variable scope to that of the file before expanding.
2690 * variable.h (recursively_expand): Make this a macro that invokes
2691 recursively_expand_for_file() with a NULL file pointer.
2692 * variable.c (target_environment): Call the renamed function and
2693 provide the current file context.
2694 Fixes Debian bug #144306.
2696 2002-04-28 Paul D. Smith <psmith@gnu.org>
2698 Allow $(call ...) user-defined variables to be self-referencing
2699 without throwing an error. Allows implementation of transitive
2700 closures, among other possibly useful things.
2701 Requested by: Philip Guenther <guenther@sendmail.com>
2703 * variable.h (struct variable): Add a new field: exp_count, and
2704 new macros to hold its size and maximum value.
2705 (warn_undefined): Make this a macro.
2706 * variable.c (define_variable_in_set): Initialize it.
2707 * expand.c (recursively_expand): If we detect recursive expansion
2708 of a variable, check the exp_count field. If it's greater than 0
2709 allow the recursion and decrement the count.
2710 (warn_undefined): Remove this (now a macro in variable.h).
2711 * function.c (func_call): Before we expand the user-defined
2712 function, modify its exp_count field to contain the maximum
2713 number of recursive calls we'll allow. After the call, reset it
2716 2002-04-21 Paul D. Smith <psmith@gnu.org>
2718 Modified to use latest autoconf (2.53), automake (1.6.1), and
2719 gettext (0.11.1). We're using gettext's new "external" support,
2720 to avoid including libintl source with GNU make.
2722 * README.cvs: New file. Explain how to build GNU make from CVS.
2724 * configure.in: Modify checking for the system glob library.
2725 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2726 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2727 etc. will manage it correctly). Set an automake conditional
2728 USE_LOCAL_GLOB to decide whether to compile the glob library.
2730 * getloadavg.c (main): Include make.h in the "TEST" program to
2733 * Makefile.am: Remove special rules for loadavg. Replace them
2734 with Automake capabilities for building extra programs.
2736 * signame.c: This file does nothing if the system provide
2737 strsignal(). If not, it implements strsignal(). If the system
2738 doesn't define sys_siglist, then we make our own; otherwise we use
2740 * signame.h: Removed.
2742 * main.c (main): No need to invoke signame_init(). Update copyright.
2744 * ABOUT-NLS: Removed.
2745 * gettext.c: Removed.
2746 * gettext.h: Get a simplified copy from the gettext package.
2748 * i18n/*.po: Moved to po/.
2751 * config/*: Created. Contains package configuration helper files.
2752 * config.guess, config.sub: Moved to config directory.
2754 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2755 Rework to use new-style autoconf features. Use the "external"
2756 mode for gettext. Make the build.sh config file conditional on
2757 whether build.sh.in exists, to avoid autoconf errors.
2758 * acinclude.m4: Removed almost all macros as being obsolete.
2759 Rewrote remaining macros to use AC_DEFINE.
2760 * acconfig.h: Removed.
2762 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2763 conditional to handle customs support. Remove special handling
2766 2002-04-20 Paul D. Smith <psmith@gnu.org>
2768 * function.c (func_call): Don't mark the argument variables $1,
2769 etc. as recursive. They've already been fully expanded so
2770 there's no need to do it again, and doing so strips escaped $'s.
2771 Reported by Sebastian Glita <glseba@yahoo.com>.
2773 * remake.c (notice_finished_file): Walk through double-colon
2774 entries via the prev field, not the next field!
2775 Reported by Greg McGary <greg@mcgary.org>.
2777 * main.c (main): If the user specifies -q and asks for a specific
2778 target which is a makefile, we got an assert. In that case it
2779 turns out we should continue normally instead.
2781 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2783 * i18n/he.po: Installed a new translation.
2785 2002-01-07 Paul D. Smith <psmith@gnu.org>
2787 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2789 2001-12-04 Paul D. Smith <psmith@gnu.org>
2791 * i18n/ja.po: Installed an updated translation.
2793 2001-09-06 Paul Eggert <eggert@twinsun.com>
2795 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2796 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2798 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2800 (main): Get rid of any avoidable limit on stack size.
2802 2001-09-04 Paul D. Smith <psmith@gnu.org>
2804 * i18n/da.po: Installed an updated translation.
2806 2001-08-03 Paul D. Smith <psmith@gnu.org>
2808 * i18n/fr.po: Installed an updated translation.
2809 Resolves Debian bug #106720.
2811 2001-06-13 Paul D. Smith <psmith@gnu.org>
2813 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2816 2001-06-11 Paul D. Smith <psmith@gnu.org>
2818 * i18n/ko.po: Installed a new translation.
2820 2001-05-06 Paul D. Smith <psmith@gnu.org>
2822 Modify the EINTR handling.
2824 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2825 the way in which we manage the file descriptor/signal handler race
2826 trap to be more efficient.
2828 2001-05-06 Paul Eggert <eggert@twinsun.com>
2830 Restart almost all system calls that are interrupted, instead
2831 of worrying about EINTR. The lone exception is the read() for
2834 * configure.in (HAVE_SA_RESTART): New macro.
2835 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2836 * main.c (main): Use SA_RESTART instead of the old,
2837 nonstandard SA_INTERRUPT.
2839 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2840 * main.c (bsd_signal): New function or macro,
2841 if the implementation doesn't supply it.
2842 (The bsd_signal function will be in POSIX 1003.1-200x.)
2843 (HANDLESIG): Remove.
2844 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2846 * make.h (EINTR_SET): Remove.
2847 (SA_RESTART): New macro.
2849 * arscan.c (ar_member_touch): Don't worry about EINTR.
2850 * function.c (func_shell): Likewise.
2851 * job.c (reap_children, free_child, new_job): Likewise.
2852 * main.c (main): Likewise.
2853 * remake.c (touch_file, name_mtime): Likewise.
2855 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2856 if fstat failed with errno!=EINTR, the error was ignored.
2858 * job.c (set_child_handler_action_flags): New function.
2859 (new_job): Use it to temporarily clear the SIGCHLD action flags
2860 while reading the token.
2862 2001-05-02 Paul D. Smith <psmith@gnu.org>
2864 * job.c (start_job_command): Don't add define/endef per-line flags
2865 to the top-level flags setting.
2867 2001-04-03 Paul D. Smith <psmith@gnu.org>
2869 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2870 bit on error, so check for odd return values, not non-0 return
2872 (VMS_get_member_info): Calculate the timezone differences correctly.
2873 Reported by John Fowler <jfowler@nyx.net>.
2876 2001-03-14 Paul D. Smith <psmith@gnu.org>
2878 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2879 value before invoking define_variable().
2880 Reported by John Fowler <jfowler@nyx.net>.
2882 2001-02-07 Paul D. Smith <psmith@gnu.org>
2884 * read.c (record_target_var): If we reset the variable due to a
2885 command-line variable setting overriding it, turn off the "append"
2888 2001-01-17 Paul D. Smith <psmith@gnu.org>
2890 * variable.c (lookup_variable) [VMS]: When getting values from the
2891 environment, allocate enough space for the _value_ plus escapes,
2892 not enough space for the name plus escapes :-/.
2893 Reported by John Fowler <jfowler@nyx.net>.
2895 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2896 warnings that make generates, so it doesn't look like an error.
2897 Reported by Karl Berry <karl@gnu.org>.
2900 Fix for PR/2020: Rework appended target-specific variables. I'm
2901 fairly confident this algorithm is finally correct.
2903 * expand.c (allocated_variable_append): Rewrite. Instead of
2904 expanding each appended variable then adding all the expanded
2905 strings together, we append all the unexpanded values going up
2906 through the variable set contexts, then expand the final result.
2907 This behaves just like non-target-specific appended variable
2908 values, while the old way didn't in various corner cases.
2909 (variable_append): New function: recursively append the unexpanded
2910 value of a variable, walking from the outermost variable scope to
2912 * variable.c (lookup_variable): Remove the code that looked up the
2913 variable set list if the found variable was "append". We don't
2915 (lookup_variable_in_set): Make this non-static so we can use it
2917 (try_variable_definition): Use lookup_variable_in_set() rather
2918 than faking out current_variable_set_list by hand (cleanup).
2919 * variable.h: Add a prototype for the now non-static
2920 lookup_variable_in_set().
2922 2000-11-17 Paul D. Smith <psmith@gnu.org>
2924 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2925 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2926 before throwing a fit.
2928 2000-11-17 Paul D. Smith <psmith@gnu.org>
2930 * read.c (readline): CRLF calculations had a hole, if you hit the
2931 buffer grow scenario just right. Reworked the algorithm to avoid
2932 the need for len or lastlen at all. Problem description with
2933 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2935 2000-10-24 Paul D. Smith <psmith@gnu.org>
2937 * gettext.c (SWAP): Declare this with the prototype, otherwise
2938 some systems don't work (non-32-bit? Reported for Cray T3E).
2939 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2941 2000-10-05 Paul D. Smith <psmith@gnu.org>
2943 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2944 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2946 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2948 2000-09-22 Paul D. Smith <psmith@gnu.org>
2950 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2951 parts of the real gettext.h here, and we expect to really include
2952 the real gettext.h later. If we keep this #define, it's ignored.
2954 2000-09-21 Paul D. Smith <psmith@gnu.org>
2956 * main.c (log_working_directory): Rework the text to use complete
2957 sentences, to make life simpler for the translators.
2959 2000-08-29 Paul D. Smith <psmith@gnu.org>
2961 * file.c (remove_intermediates): Print a debug message before we
2962 remove intermediate files, so the user (if she uses -d) knows
2965 2000-08-21 Paul D. Smith <psmith@gnu.org>
2967 * variable.c (try_variable_definition): Change how we handle
2968 target-specific append variable defns: instead of just setting the
2969 value, expand it as an append _but_ only within the current
2970 target's context. Otherwise we lose all but the last value if the
2971 variable is appended more than once within the current target
2972 context. Fixes PR/1831.
2974 2000-08-16 Paul D. Smith <psmith@gnu.org>
2976 * function.c (func_shell): Nul-terminate the buffer before
2977 printing an exec error message (just in case it's not!).
2978 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2980 2000-07-25 Paul D. Smith <psmith@gnu.org>
2982 * job.c (construct_command_argv_internal): Add "~" to the list of
2983 sh_chars[] which disallow optimizing out the shell call.
2985 2000-07-23 Paul Eggert <eggert@twinsun.com>
2987 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2988 supersedes --disable-nsec-timestamps.
2989 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2990 * README: Remove --disable-nsec-timestamps.
2992 * filedef.h (struct file.low_resolution_time): New member.
2993 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2994 * remake.c (update_file_1):
2995 Avoid spurious rebuilds due to low resolution time stamps,
2996 generalizing the earlier code that applied only to archive members.
2997 (f_mtime): Archive members always have low resolution time stamps.
2999 * configure.in: Remove --disable-nsec-timestamps, as this has
3000 been superseded by .LOW_RESOLUTION_TIME.
3002 2000-07-23 Paul Eggert <eggert@twinsun.com>
3004 * configure.in (enable_nsec_timestamps): Renamed from
3005 make_cv_nsec_timestamps, since enable/disable options
3006 shouldn't be cached.
3008 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3009 and Paul Eggert <eggert@twinsun.com>
3011 * file.c (file_timestamp_now):
3012 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3013 so that clock_gettime is not linked unless needed.
3015 * filedef.h (FILE_TIMESTAMP_HI_RES):
3016 Remove definition; "configure" now does this.
3018 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3019 to before high resolution file timestamp check,
3020 since that check now uses uintmax_t.
3021 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3022 high resolution file timestamps.
3023 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3024 so that we don't link in clock_gettime unnecessarily.
3026 2000-07-17 Paul D. Smith <psmith@gnu.org>
3028 * i18n/ja.po: New version of the translation file.
3030 2000-07-07 Paul D. Smith <psmith@gnu.org>
3032 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3033 the offset calculation.
3034 (name_mtime): Replace EINTR test with EINTR_SET macro.
3036 2000-07-07 Paul Eggert <eggert@twinsun.com>
3040 * remake.c (update_file_1):
3041 Avoid spurious rebuilds of archive members due to their
3042 timestamp resolution being only one second.
3043 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3044 the clock's resolution being lower than file timestamps'.
3045 When warning about future timestamps, report only the discrepancy,
3046 not the absolute value of the timestamp and the current time.
3048 * file.c (file_timestamp_now): New arg RESOLUTION.
3049 * filedef.h (file_timestamp_now): Likewise.
3050 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3052 2000-07-05 Paul D. Smith <psmith@gnu.org>
3054 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3055 to listp. Fixes PR/1793.
3057 2000-06-26 Paul Eggert <eggert@twinsun.com>
3059 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3061 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3063 * remake.c (f_mtime): Remove unused var memtime.
3065 2000-06-25 Martin Buchholz <martin@xemacs.org>
3067 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3068 Ran spell-check on make.texinfo.
3070 2000-06-23 Paul D. Smith <psmith@gnu.org>
3072 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3073 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3074 * make.h: Define these macros.
3076 * Version 3.79.1 released.
3078 * configure.in: Add a new option, --disable-nsec-timestamps, to
3079 avoid using sub-second timestamps on systems that support it. It
3080 can lead to problems, e.g. if your makefile relies on "cp -p".
3081 * README.template: Document the issue with "cp -p".
3083 * config.guess, config.sub: Updated.
