3 * ALL: Use the strcache for all file name strings, or other
4 strings which we will never free. The goal is to save memory by
5 avoiding duplicate copies of strings. However, at the moment this
6 doesn't save much memory in most situations: due to secondary
7 expansion we actually save prerequisite lists twice (once before
8 the secondary expansion, and then again after it's been parsed
9 into individual file names in the dep list). We will resolve this
10 in a future change, by doing the parsing up-front for targets
11 where secondary expansion is not set.
13 Moving things into the strcache also allows us to use const
14 pointers in many more places.
16 2007-01-03 Paul Smith <psmith@gnu.org>
18 * make.h (ENULLLOOP): Reset errno after each failed invocation of
19 the function, not just the first. Fixes Savannah bug #18680.
21 2006-11-18 Paul Smith <psmith@gnu.org>
23 * strcache.c (strcache_add_len): Don't allocate a new buffer
24 unless the string is not already nil-terminated. Technically this
25 is a violation of the standard, since we may be passed an array
26 that is not long enough to test one past. However, in make this
27 is never true since we only use nil-terminated strings or
30 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
32 * main.c: New global cmd_prefix, defaults to '\t'.
33 * job.c (construct_command_argv_internal): Use cmd_prefix instead

124 2006-04-20 Paul D. Smith <psmith@gnu.org>
126 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
127 that don't have extended grep.
128 (cvsclean): Use $(PERL) instead of perl.
130 2006-04-09 Paul D. Smith <psmith@gnu.org>

196 Declare and define sh_chars_sh[].
198 2006-03-23 Paul D. Smith <psmith@gnu.org>
200 * configure.in: Look for build.sh.in in $srcdir so it will be
201 built for remote configurations as well.
203 * Makefile.am: Make sure to clean up build.sh during distclean.
204 Fixes Savannah bug #16166.
206 * misc.c (log_access): Takes a const char *.

227 (main): If we are re-execing, clean up the jobserver first so we
228 don't leak file descriptors.
229 Fix bug reported by Craig Fithian <craig.fithian@citigroup.com>.
231 2006-03-17 Paul D. Smith <psmith@gnu.org>

258 Fixes Savannah bug #15913.
260 2006-03-09 Paul Smith <psmith@gnu.org>
262 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
263 listed non-existent files as changed. Turns out there's a bug in
264 the Linux kernel builds which means that this change causes
265 everything to rebuild every time. We will re-introduce this fix
266 in the next release, to give them time to fix their build system.
267 Fixes Savannah bug #16002.
268 Introduces Savannah bug #16051.
270 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

287 * commands.c (set_file_variables): Realloc, not malloc, the static
288 string values to avoid memory leaks.
290 * expand.c (recursively_expand_for_file): Only set reading_file to
291 an initialized value.
293 * implicit.c (pattern_search): We need to make a copy of the stem
294 if we get it from an intermediate dep, since those get freed.
296 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
298 (enter_file) [VMS]: Ditto.
299 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

305 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
306 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
307 the calls to _beginthreadex.
309 * expand.c (recursively_expand_for_file): Initialize `save' to
310 prevent compiler warnings.
312 2006-02-18 Eli Zaretskii <eliz@gnu.org>
314 * job.c (construct_command_argv_internal): Don't create a temporary
315 script/batch file if we are under -n. Call _setmode to switch the
316 script file stream to text mode.
318 2006-02-17 Paul D. Smith <psmith@gnu.org>
320 * variable.c (merge_variable_set_lists): Don't try to merge the
321 global_setlist. Not only is this useless, but it can lead to
322 circularities in the linked list, if global_setlist->next in one
323 list gets set to point to another list which also ends in
325 Fixes Savannah bug #15757.
327 2006-02-15 Paul D. Smith <psmith@gnu.org>
329 Fix for Savannah bug #106.
331 * expand.c (expanding_var): Keep track of which variable we're
332 expanding. If no variable is being expanded, it's the same as
334 * make.h (expanding_var): Declare it.
335 * expand.c (recursively_expand_for_file): Set expanding_var to the
336 current variable we're expanding, unless there's no file info in
337 it (could happen if it comes from the command line or a default
338 variable). Restore it before we exit.
339 * expand.c (variable_expand_string): Use the expanding_var file
340 info instead of the reading_file info.

350 * read.c (eval): Even if the included filenames expands to the
351 empty string we still need to free the allocated buffer.
353 * implicit.c (pattern_search): If we allocated a variable set for
354 an impossible file, free it.
355 * variable.c (free_variable_set): New function.
356 * variable.h: Declare it.
358 * read.c (read_all_makefiles): Makefile names are kept in the
359 strcache, so there's never any need to alloc/free them.
362 * main.c (main): Add "archives" to the .FEATURES variable if
363 archive support is enabled.
364 * doc/make.texi (Special Variables): Document it.
366 2006-02-13 Paul D. Smith <psmith@gnu.org>
368 * implicit.c (pattern_search): Add checking for DOS pathnames to
369 the pattern rule target LASTSLASH manipulation.

374 * (ALL FILES): Updated copyright and license notices.
376 2006-02-10 Paul D. Smith <psmith@gnu.org>
378 A new internal capability: the string cache is a read-only cache
379 of strings, with a hash table interface for fast lookup. Nothing
380 in the cache will ever be freed, so there's no need for reference
381 counting, etc. This is the beginning of a full solution for
382 Savannah bug #15182, but for now we only store makefile names here.
384 * strcache.c: New file. Implement a read-only string cache.
385 * make.h: Add prototypes for new functions.
386 * main.c (initialize_global_hash_tables): Initialize the string cache.
387 (print_data_base): Print string cache stats.
388 * read.c (eval_makefile): Use the string cache to store makefile
389 names. Rewrite the string allocation to be sure we free everything.

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

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

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

466 2006-01-21 Eli Zaretskii <eliz@gnu.org>
468 * remake.c (update_goal_chain): Set g->changed instead of
469 incrementing it, as it is only 8-bit wide, and could overflow if

531 handling of backslash-newline sequences. Mention the differences
532 on MS-DOS and MS-Windows.
534 * NEWS: More details about building the MinGW port and a pointer
535 to README.W32. Fix the section name that describes the new
536 backward-incompatible processing of backslash-newline sequences.
537 The special processing of SHELL set to "cmd" is only relevant to
538 MS-Windows, not MS-DOS.
540 2005-12-17 Eli Zaretskii <eliz@gnu.org>

559 * read.c (record_target_var): Initialize variable's export field
560 with v_default instead of leaving it "initialized" by whatever
561 garbage happened to be on the heap.
563 2005-12-12 Paul D. Smith <psmith@gnu.org>
565 * make.1: Fix some display errors and document all existing options.
566 Patch provided by Mike Frysinger <vapier@gentoo.org>.
568 2005-12-11 Paul D. Smith <psmith@gnu.org>
570 * implicit.c (pattern_search): If 2nd expansion is not set for
571 this implicit rule, replace the pattern with the stem directly,
572 and don't re-expand the variable list. Along with the other
573 .SECONDEXPANSION changes below, fixes bug #13781.
575 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
577 * implicit.c (pattern_search): Mark other files that this rule
578 builds as targets so that they are not treated as intermediates
579 by the pattern rule search algorithm. Fixes bug #13022.
581 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
583 * remake.c (notice_finished_file): Propagate the change of
584 modification time to all the double-colon entries only if
585 it is the last one to be updated. Fixes bug #14334.
587 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
589 * function.c (func_flavor): Implement the flavor function which
590 returns the flavor of a variable.
591 * doc/make.texi (Functions for Transforming Text): Document it.
592 * NEWS: Add it to the list of new functions.
594 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
596 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
598 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
599 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
601 2005-10-26 Paul Smith <psmith@gnu.org>
603 * read.c (record_files): Don't set deps flags if there are no deps.
604 * maintMakefile: We only need to build the templates when we are
605 creating a distribution, so don't do it for "all".
607 2005-10-24 Paul D. Smith <psmith@gnu.org>
609 Make secondary expansion optional: its enabled by declaring the
610 special target .SECONDEXPANSION.
612 * NEWS: Update information on second expansion capabilities.
613 * doc/make.texi (Secondary Expansion): Document the
614 .SECONDEXPANSION special target and its behavior.
615 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
616 prerequisite list was found in a static pattern rule.
617 (free_dep_chain): Declare a prototype.
618 * file.c (parse_prereqs): New function: break out some complexity
620 (expand_deps): If we aren't doing second expansion, replace % with
621 the stem for static pattern rules. Call the new function.
622 * filedef.h (parse_prereqs): Declare a prototype.
623 * implicit.c (pattern_search): Initialize the new staticpattern
625 * main.c (second_expansion): Declare a global variable to remember
626 if the special target has been seen. Initialize the new
627 staticpattern field for prerequisites.
628 * make.h: Extern for second_expansion.
629 * misc.c (free_dep_chain): New function: frees a struct dep list.
630 * read.c (read_all_makefiles): Initialize the staticpattern field.
631 (eval_makefile): Ditto.
632 (record_files): Check for the .SECONDEXPANSION target and set
633 second_expansion global if it's found.
634 Use the new free_dep_chain() instead of doing it by hand.
635 Set the staticpattern field for prereqs of static pattern targets.
637 2005-10-16 Paul D. Smith <psmith@gnu.org>
639 * main.c (main): Set CURDIR to be a file variable instead of a
640 default, so that values of CURDIR inherited from the environment
641 won't override the make value.
643 2005-09-26 Paul D. Smith <psmith@gnu.org>
645 * job.c (construct_command_argv_internal): If the line is empty
646 remember to free the temporary argv strings.
649 2005-09-16 Paul D. Smith <psmith@gnu.org>
651 * job.c (start_job_command): The noerror flag is a boolean (single
652 bit); set it appropriately.
653 Reported by Mark Eichin <eichin@metacarta.com>
655 2005-08-29 Paul D. Smith <psmith@gnu.org>
657 * function.c (func_error): On Windows, output from $(info ...)
658 seems to come in the wrong order. Try to force it with fflush().
660 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
662 * read.c (record_files): Move code that sets stem for static
663 pattern rules out of the if (!two_colon) condition so it is
664 also executed for two-colon rules. Fixes Savannah bug #13881.
666 2005-08-08 Paul D. Smith <psmith@gnu.org>
668 * make.h: Don't test that __STDC__ is non-0. Some compilers
669 (Windows for example) set it to 0 to denote "ISO C + extensions".
672 2005-08-07 Paul D. Smith <psmith@gnu.org>
674 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
675 conditional (slightly different version of a fix from Eli).
677 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
678 If make is running in parallel without -k and two jobs die in a
679 row, but not too close to each other, then make will quit without
680 waiting for the rest of the jobs to die.
682 * main.c (die): Don't reset err before calling reap_children() the
683 second time: we still want it to be in the error condition.
684 * job.c (reap_children): Use a static variable, rather than err,
685 to control whether or not the error message should be printed.
687 2005-08-06 Eli Zaretskii <eliz@gnu.org>
689 * w32/subproc/sub_proc.c: Include signal.h.
690 (process_pipe_io, process_file_io): Pass a pointer to a local
691 DWORD variable to GetExitCodeProcess. If the exit code is
692 CONTROL_C_EXIT, put SIGINT into pproc->signal.
694 * job.c [WINDOWS32]: Include windows.h.
695 (main_thread) [WINDOWS32]: New global variable.
696 (reap_children) [WINDOWS32]: Get the handle for the main thread
697 and store it in main_thread.
699 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
700 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
701 doing anything else. When we are done, close the main thread
702 handle and exit with status 130.
704 2005-07-30 Eli Zaretskii <eliz@gnu.org>
706 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
709 * main.c (find_and_set_default_shell): If found a DOSish shell,
710 set sh_found and the value of default_shell, and report the
711 findings in debug mode.
713 * job.c (construct_command_argv_internal): Check unixy_shell, not
714 no_default_sh_exe, to decide whether to use Unixy or DOSish
717 * README.W32: Update with info about the MinGW build.
719 * build_w32.bat: Support MinGW.
721 * w32/subproc/build.bat: Likewise.
723 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
726 * function.c (windows32_openpipe): Fix format strings for printing
729 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
731 (start_job_command): Fix format string for printing the result of
733 (start_job_command) [WINDOWS32]: Do not define.
734 (exec_command): Fix format string for printing HANDLE args.
736 * main.c (handle_runtime_exceptions): Fix sprintf format strings
737 to avoid compiler warnings.
738 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
739 (Note: some of these fixes were submitted independently by J. Grant)
741 2005-07-30 J. Grant <jg@jguk.org>
743 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
744 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
745 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
747 2005-07-15 Paul Smith <psmith@gnu.org>
749 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
750 we don't have a POSIX shell, then revert to the old
751 backslash-newline behavior (where they are stripped).
754 2005-07-08 Paul D. Smith <psmith@gnu.org>
756 * config.h.W32.template: Reorder to match the standard config.h,
757 for easier comparisons.
758 From J. Grant <jg@jguk.org>
760 * maintMakefile: Remove .dep_segment before overwriting it, in
761 case it's not writable or noclobber is set.
762 * expand.c (variable_expand_string): Cast result of pointer
763 arithmetic to avoid a warning.
764 * main.c (switches): Add full-fledged final initializer.
766 2005-07-06 Paul D. Smith <psmith@gnu.org>
768 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
769 * signame.c (strsignal): If we found _sys_siglist[] or
770 __sys_siglist[] use those instead of sys_siglist[].
771 From Albert Chin <china@thewrittenword.com>
773 2005-07-04 Paul D. Smith <psmith@gnu.org>
775 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
776 globfree(); set up to use the GNU versions.
777 From Martin Zinser <zinser@zinser.no-ip.info>
779 2005-07-03 Paul D. Smith <psmith@gnu.org>
781 From J. Grant <jg@jguk.org>:
783 * README.W32.template: Update the Windows and tested MSVC versions.
784 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
785 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
786 * build_w32.bat: Ditto.
787 * w32/subproc/build.bat: Ditto.
789 2005-06-28 Paul D. Smith <psmith@gnu.org>
791 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
792 declaration was checked but not present.
794 2005-06-27 Paul D. Smith <psmith@gnu.org>
796 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
797 to unsigned long. Fixes Savannah bug #13550.
799 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
800 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
801 Fixes Savannah bug #13551.
803 2005-06-26 Paul D. Smith <psmith@gnu.org>
805 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
806 it if ANSI_STRING is not set.
808 2005-06-25 Paul D. Smith <psmith@gnu.org>
810 * read.c (eval): If no filenames are passed to any of the
811 "include" variants, don't print an error.
812 * doc/make.texi (Include): Document this.
813 Fixes Savannah bug #1761.
815 * job.c (construct_command_argv_internal): Sanitize handling of
816 backslash/newline pairs according to POSIX: that is, keep the
817 backslash-newline in the command script, but remove a following
818 TAB character, if present. In the fast path, make sure that the
819 behavior matches what the shell would do both inside and outside
820 of quotes. In the slow path, quote the backslash and put a
821 literal newline in the string.
822 Fixes Savannah bug #1332.
823 * doc/make.texi (Execution): Document the new behavior and give
825 * NEWS: Make a note of the new behavior.
827 * make.h [WINDOWS32]: #include <direct.h>.
828 Fixes Savannah bug #13478.
830 * remake.c (name_mtime): If the stat() of a file fails and the -L
831 option was given and the file is a symlink, take the best mtime of
832 the symlink we can get as the mtime of the file and don't fail.
833 Fixes Savannah bug #13280.
835 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
836 If it's set, then don't stop on STOPCHARs or BLANKs if they're
837 inside a variable reference. Make this function static as it's
839 (eval): Call find_char_unquote() with IGNOREVARS set when we're
840 parsing an unexpanded line looking for semicolons.
841 Fixes Savannah bug #1454.
842 * misc.c (remove_comments): Move this to read.c and make it static
843 as it's only used there. Call find_char_unquote() with new arg.
844 * make.h: Remove prototypes for find_char_unquote() and
845 remove_comments() since they're static now.
847 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
848 its export flag and obtain its value. When we need to re-exec,
849 increment the value and add it into the environment.
850 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
851 * NEWS: Mention MAKE_RESTARTS.
852 * main.c (always_make_set): New variable. Change the -B option to
853 set this one instead.
854 (main): When checking makefiles, only set always_make_flag if
855 always_make_set is set AND the restarts flag is 0. When building
856 normal targets, set it IFF always_make_set is set.
857 (main): Avoid infinite recursion with -W, too: only set what-if
858 files to NEW before we check makefiles if we've never restarted
859 before. If we have restarted, set what-if files to NEW _after_ we
861 Fixes Savannah bug #7566:
863 2005-06-17 Paul D. Smith <psmith@gnu.org>
865 * default.c: Change VMS implicit rules to use $$$$ instead of $$
866 in the prerequisites list.
868 2005-06-12 Paul D. Smith <psmith@gnu.org>
870 Fix Savannah bug # 1328.
872 * configure.in: Check for atexit().
873 * misc.c (close_stdout): Test stdout to see if writes to it have
874 failed. If so, be sure to exit with a non-0 error code. Based on
875 code found in gnulib.
877 * main.c (main): Install close_stdout() with atexit().
879 2005-06-10 Paul D. Smith <psmith@gnu.org>
881 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
883 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
884 headers; make vmsWaitForChildren() static; extern vmsify().
885 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
886 Don't create child_execute_job() here (it's in vmsjobs.c).
887 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
889 2005-06-09 Paul D. Smith <psmith@gnu.org>
891 * variable.c (push_new_variable_scope): File variables point
892 directly to the global_setlist variable. So, inserting a new
893 scope in front of that has no effect on those variables: they
894 don't go through current_variable_set_list. If we're pushing a
895 scope and the current scope is global, push it "the other way" so
896 that the new setlist is in the global_setlist variable, and
897 next points to a new setlist with the global variable set.
898 (pop_variable_scope): Properly undo a push with the new
900 Fixes Savannah bug #11913.
902 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
904 * job.c (reap_children): Don't die of the command failed but
905 the dontcare flag is set. Fixes Savannah bug #13216.
907 * implicit.c (pattern_search): When creating a target from
908 an implicit rule match, lookup pattern target and set precious
909 flag in a newly created target. Fixes Savannah bug #13218.
911 2005-05-13 Paul D. Smith <psmith@gnu.org>
913 Implement "if... else if... endif" syntax.
915 * read.c (eval): Push all checks for conditional words ("ifeq",
916 "else", etc.) down into the conditional_line() function.
917 (conditional_line): Rework to allow "else if..." clause. New
918 return value -2 for lines which are not conditionals. The
919 ignoring flag can now also be 2, which means "already parsed a
920 true branch". If that value is seen no other branch of this
921 conditional can be considered true. In the else parsing if there
922 is extra text after the else, invoke conditional_line()
923 recursively to see if it's another conditional. If not, it's an
924 error. If so, raise the conditional value to this level instead
925 of creating a new conditional nesting level. Special check for
926 "else" and "endif", which aren't allowed on the "else" line.
927 * doc/make.texi (Conditional Syntax): Document the new syntax.
929 2005-05-09 Paul D. Smith <psmith@gnu.org>
931 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
932 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
933 recurses to the w32 directory, even on non-Windows systems. Use
934 the method suggested in the automake manual.
935 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
936 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
938 2005-05-07 Paul D. Smith <psmith@gnu.org>
940 * main.c (die): If we're dying with a fatal error (not that a
941 command has failed), write back any leftover tokens before we go.
943 * job.c (set_child_handler_action_flags): If there are jobs
944 waiting for the load to go down, set an alarm to go off in 1
945 second. This allows us to wake up from a potentially long-lasting
946 read() and start a new job if the load has gone down. Turn it off
948 (job_noop): Dummy signal handler function.
949 (new_job): Invoke it with the new semantics.
951 * docs/make.texi: Document secondary expansion. Various cleanups
954 2005-05-03 Paul D. Smith <psmith@gnu.org>
956 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
957 the targets which are to ultimately be made are called "goals";
958 see the GNU make manual. Also, MAKECMDGOALS, etc.
960 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
961 .DEFAULT_GOAL, and default_target_name to default_goal_name.
962 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
964 2005-05-02 Paul D. Smith <psmith@gnu.org>
966 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
967 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
968 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
969 functions to vmsjobs.c. #include it into jobs.c.
971 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
972 jobserver tokens. I found that this happens when an exported
973 recursive variable contains a $(shell ...) function reference: in
974 this situation we could "forget" to write back a token.
976 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
977 we have. It's not reliable to depend on the number of children in
978 our linked list so keep a separate count.
979 (new_job): Check jobserver_tokens rather than children &&
980 waiting_jobs. Increment jobserver_tokens when we get one.
981 (free_child): If jobserver_tokens is 0, internal error. If it's
982 >1, write a token back to the jobserver pipe (we don't write a
983 token for the "free" job). Decrement jobserver_tokens.
985 * main.c: Add variable master_job_slots.
986 (main): Set it to hold the number of jobs requested if we're the
987 master process, when using the jobserver.
988 (die): Sanity checks: first test jobserver_tokens to make sure
989 this process isn't holding any tokens we didn't write back.
990 Second, if master_job_slots is set count the tokens left in the
991 jobserver pipe and ensure it's the same as master_job_slots (- 1).
993 2005-04-24 Paul D. Smith <psmith@gnu.org>
995 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
996 with -l# can lose jobserver tokens, because waiting jobs are not
997 consulted properly when checking for the "free" token.
999 * job.c (free_child): Count waiting_jobs as having tokens.
1000 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1001 handle jobs waiting for the load to drop.
1003 2005-04-23 Paul D. Smith <psmith@gnu.org>
1005 * main.c (main): Be careful to not core if a variable setting in
1006 the environment doesn't contain an '='. This is illegal but can
1007 happen in broken setups.
1008 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1010 2005-04-12 Paul D. Smith <psmith@gnu.org>
1012 The second expansion feature causes significant slowdown. Timing
1013 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1014 read the makefile before the feature, to 11+s to do the same
1015 operations after the feature. Additionally, memory usage
1016 increased drastically. To fix this I added some intelligence that
1017 avoids the overhead of the second expansion unless it's required.
1019 * dep.h: Add a new boolean field, need_2nd_expansion.
1021 * read.c (eval): When creating the struct dep for the target,
1022 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1023 (record_files): If there's a "%" in a static pattern rule, it gets
1024 converted to "$*" so set need_2nd_expansion to 1.
1026 * file.c (expand_deps): Rework to be more efficient. Only perform
1027 initialize_file_variables(), set_file_variables(), and
1028 variable_expand_for_file() if the need_2nd_expansion is set.
1030 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1031 (pattern_search): Ditto.
1032 * main.c (handle_non_switch_argument): Ditto.
1034 * read.c (read_all_makefiles): Ditto.
1035 (eval_makefile): Ditto.
1037 2005-04-07 Paul D. Smith <psmith@gnu.org>
1039 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1040 * variable.c (sync_Path_environment): Ditto.
1041 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1043 * main.c (main): Define the .FEATURES variable.
1044 * NEWS: Announce .FEATURES.
1045 * doc/make.texi (Special Variables): Document .FEATURES.
1047 * remake.c (check_dep): If a file is .PHONY, update it even if
1048 it's marked intermediate. Fixes Savannah bug #12331.
1050 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1052 * file.c (expand_deps): Factor out the second expansion and
1053 prerequisite line parsing logic from snap_deps().
1055 * file.c (snap_deps): Use expand_deps(). Expand and parse
1056 prerequisites of the .SUFFIXES special target first. Fixes
1057 Savannah bug #12320.
1059 2005-03-13 Paul D. Smith <psmith@gnu.org>
1061 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1064 2005-03-11 Paul D. Smith <psmith@gnu.org>
1066 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1067 available, not undefined (from Earnie Boyd).
1069 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1071 * implicit.c (pattern_search): Mark an intermediate target as
1072 precious if it happened to be a prerequisite of some (other)
1073 target. Fixes Savannah bug #12267.
1075 2005-03-09 Paul D. Smith <psmith@gnu.org>
1077 * read.c (eval_makefile): Add alloca(0).
1078 (eval_buffer): Ditto.
1080 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1082 * main.c (main): Use o_file instead of o_default when defining
1083 the .DEFAULT_TARGET special variable.
1084 * read.c (eval): Use define_variable_global() instead of
1085 define_variable() when setting new value for the .DEFAULT_TARGET
1086 special variable. Fixes Savannah bug #12266.
1088 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1090 * imlicit.c (pattern_search): Mark files for which an implicit
1091 rule has been found as targets. Fixes Savannah bug #12202.
1093 2005-03-04 Paul D. Smith <psmith@gnu.org>
1096 * doc/make.texi (Automatic Variables): Document $|.
1098 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1100 * read.c (record_files): Instead of substituting % with
1101 actual stem value in dependency list replace it with $*.
1102 This fixes stem triple expansion bug.
1104 * implicit.c (pattern_search): Copy stem to a separate
1105 buffer and make it a properly terminated string. Assign
1106 this buffer instead of STEM (which is not terminated) to
1107 f->stem. Instead of substituting % with actual stem value
1108 in dependency list replace it with $*. This fixes stem
1109 triple expansion bug.
1111 2005-03-01 Paul D. Smith <psmith@gnu.org>
1113 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1114 on Windows, as it takes a handle not a pid. Just exit.
1115 Fix from patch #3679, provided by Alessandro Vesely.
1117 * configure.in: Update check for sys_siglist[] from autoconf manual.
1118 * signame.c (strsignal): Update to use the new autoconf macro.
1120 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1122 * read.c (record_files): Add a check for the list of prerequisites
1123 of a static pattern rule being empty. Fixes Savannah bug #12180.
1125 2005-02-28 Paul D. Smith <psmith@gnu.org>
1127 * doc/make.texi (Text Functions): Update docs to allow the end
1128 ordinal for $(wordlist ...) to be 0.
1129 * function.c (func_wordlist): Fail if the start ordinal for
1130 $(wordlist ...) is <1. Matches documentation.
1131 Resolves Savannah support request #103195.
1133 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1134 previously we were stopping when !-q, exactly the opposite. This
1135 has been wrong since version 1.34, in 1994!
1136 (update_file): If we got an error don't break out to run more
1137 double-colon rules: just return immediately.
1138 Fixes Savannah bug #7144.
1140 2005-02-27 Paul D. Smith <psmith@gnu.org>
1142 * misc.c (end_of_token): Make argument const.
1143 * make.h: Update prototype.
1145 * function.c (abspath, func_realpath, func_abspath): Use
1146 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1147 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1148 * read.c (record_files): Ditto.
1149 * variable.c (do_variable_definition): Ditto.
1151 * function.c (func_error): Create a new function $(info ...) that
1152 simply prints the message to stdout with no extras.
1153 (function_table_init): Add new function to the table.
1154 * NEWS: Add $(info ...) reference.
1155 * doc/make.texi (Make Control Functions): Document it.
1157 New feature: if the system supports symbolic links, and the user
1158 provides the -L/--check-symlink-time flag, then use the latest
1159 mtime between the symlink(s) and the target file.
1161 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1162 readlink(). If both are available, define MAKE_SYMLINKS.
1163 * main.c: New variable: check_symlink_flag.
1164 (usage): Add a line for -L/--check-symlink-times to the help string.
1165 (switches): Add -L/--check-symlink-times command line argument.
1166 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1167 print a warning and disable it again.
1168 * make.h: Declare check_symlink_flag.
1169 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1170 if the file is a symlink then check each link in the chain and
1171 choose the NEWEST mtime we find as the mtime for the file. The
1172 newest mtime might be the file itself!
1173 * NEWS: Add information about this new feature.
1174 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1176 Avoid core dumps described in Savannah bug # 12124:
1178 * file.c: New variable snapped_deps remember whether we've run
1180 (snap_deps): Set it.
1181 * filedef.h: Extern it.
1182 * read.c (record_files): Check snapped_deps; if it's set then
1183 we're trying to eval a new target/prerequisite relationship from
1184 within a command script, which we don't support. Fatal.
1186 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1188 Implementation of the .DEFAULT_TARGET special variable.
1190 * read.c (eval): If necessary, update default_target_name when
1192 * read.c (record_files): Update default_target_file if
1193 default_target_name has changed.
1194 * main.c (default_target_name): Define.
1195 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1196 default_target_name is set use default_target_file as a root
1198 * filedef.h (default_target_name): Declare.
1199 * dep.h (free_dep_chain):
1200 * misc.c (free_dep_chain): Change to operate on struct nameseq
1201 and change name to free_ns_chain.
1202 * file.c (snap_deps): Update to use free_ns_chain.
1204 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1206 Implementation of the second expansion in explicit rules,
1207 static pattern rules and implicit rules.
1209 * read.c (eval): Refrain from chopping up rule's dependencies.
1210 Store them in a struct dep as a single dependency line. Remove
1211 the code that implements SySV-style automatic variables.
1213 * read.c (record_files): Adjust the code that handles static
1214 pattern rules to expand all percents instead of only the first
1215 one. Reverse the order in which dependencies are stored so that
1216 when the second expansion reverses them again they appear in
1217 the makefile order (with some exceptions, see comments in
1218 the code). Remove the code that implements SySV-style automatic
1221 * file.c (snap_deps): Implement the second expansion and chopping
1222 of dependency lines for explicit rules.
1224 * implicit.c (struct idep): Define an auxiliary data type to hold
1225 implicit rule's dependencies after stem substitution and
1228 * implicit.c (free_idep_chain): Implement.
1230 * implicit.c (get_next_word): Implement helper function for
1231 parsing implicit rule's dependency lines into words taking
1232 into account variable expansion requests. Used in the stem
1235 * implicit.c (pattern_search): Implement the second expansion
1236 for implicit rules. Also fixes bug #12091.
1238 * commands.h (set_file_variables): Declare.
1239 * commands.c (set_file_variables): Remove static specifier.
1241 * dep.h (free_dep_chain): Declare.
1242 * misc.c (free_dep_chain): Implement.
1244 * variable.h (variable_expand_for_file): Declare.
1245 * expand.c (variable_expand_for_file): Remove static specifier.
1247 * make.h (strip_whitespace): Declare.
1248 * function.c (strip_whitespace): Remove static specifier.
1250 2005-02-26 Paul D. Smith <psmith@gnu.org>
1252 * main.c (main): Check for ferror() when reading makefiles from stdin.
1253 Apparently some shells in Windows don't close pipes properly and
1256 2005-02-24 Jonathan Grant <jg@jguk.org>
1258 * configure.in: Add MinGW configuration options, and extra w32 code
1260 * Makefile.am: Add MinGW configuration options, and extra w32 code
1262 * main.c: Determine correct program string (after last \ without .exe).
1263 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1265 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1266 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1267 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1268 environment support.
1270 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1272 * function.c (func_shell): When initializing error_prefix, check
1273 that reading file name is not null. This fixes long-standing
1274 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1276 2005-02-09 Paul D. Smith <psmith@gnu.org>
1278 * maintMakefile: Update the CVS download URL to simplify them.
1279 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1280 downloading the .texi files from Savannah now.
1282 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1284 * main.c (handle_non_switch_argument): Only add variables to
1285 command_variables if they're not already there: duplicate settings
1286 waste space and can be confusing to read.
1288 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1289 this header is never included by non-WINDOWS32 code, and it
1290 requires <config.h> to define which isn't always included first.
1292 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1293 testing MINGW32 versions.
1295 * main.c (log_working_directory): flush stdout to be sure the WD
1296 change is printed before any stderr messages show up.
1298 2005-02-01 Paul D. Smith <psmith@gnu.org>
1300 * maintMakefile (po_repo): Update the GNU translation site URL.
1302 2004-12-01 Paul D. Smith <psmith@gnu.org>
1304 * main.c (main): Change char* env_shell to struct variable shell_var.
1305 * variable.c (target_environment): Use new shell_var.
1307 2004-11-30 Paul D. Smith <psmith@gnu.org>
1309 * configure.in: The old way we avoided creating build.sh from
1310 build.sh.in before build.sh.in exists doesn't work anymore; we
1311 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1312 the help!). This also keeps automake from complaining.
1313 * Makefile.am (README): Add a dummy target so automake won't
1314 complain that this file doesn't exist when we checkout from CVS.
1315 * maintMakefile (.dep_segment): Rewrite this rule since newer
1316 versions of automake don't provide DEP_FILES.
1318 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1320 Implementation of `realpath' and `abspath' built-in functions.
1322 * configure.in: Check for realpath.
1323 * function.c (abspath): Return an absolute file name that does
1324 not contain any `.' or `..' components, nor repeated `/'.
1325 * function.c (func_abspath): For each name call abspath.
1326 * function.c (func_realpath): For each name call realpath
1327 from libc or delegate to abspath if realpath is not available.
1328 * doc/make.texi (Functions for File Names): Document new functions.
1329 * doc/make.texi (Quick Reference): Ditto.
1331 2004-11-28 Paul D. Smith <psmith@gnu.org>
1333 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1334 arguments. Fixes bug #10252.
1336 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1338 * main.c (main): Set SHELL to v_noexport by default. Remember the
1339 original environment setting of SHELL in the env_shell variable.
1340 * main.h: Export new env_shell variable.
1341 * variable.c (target_environment): If we find a v_noexport
1342 variable for SHELL, add a SHELL variable with the env_shell value.
1343 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1344 * doc/make.texi (Variables/Recursion): Ditto.
1346 2004-11-28 Paul D. Smith <psmith@gnu.org>
1348 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1349 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1350 Patch by Alessandro Vesely.
1352 2004-11-12 Paul D. Smith <psmith@gnu.org>
1354 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1355 the command line if it's inside a string.
1356 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1358 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1360 * function.c (func_lastword): New function: return last word
1361 from the list of words.
1362 * doc/make.texi: Document $(lastword ). Fix broken links in
1363 Quick Reference section.
1365 2004-10-06 Paul D. Smith <psmith@gnu.org>
1367 Apply patch from Alessandro Vesely, provided with bug # 9748.
1368 Fix use of tmpnam() to work with Borland C.
1370 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1371 construction of a temporary filename, and call new function
1372 create_batch_filename().
1373 (create_batch_filename) [WINDOWS32]: New function to create a
1376 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1378 * read.c (record_target_var): Expand simple pattern-specific
1380 * variable.c (initialize_file_variables): Do not expand simple
1381 pattern-specific variable.
1383 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1385 * remake.c (update_file_1): When rebuilding makefiles inherit
1386 dontcare flag from a target that triggered update.
1388 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1390 * variable.c (initialize_file_variables): Mark pattern-specific
1391 variable as a per-target and copy export status.
1393 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1395 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1397 * implicit.c (pattern_search): When considering an implicit rule's
1398 prerequisite check that it is actually a target rather then
1399 just an entry in the file hashtable.
1401 2004-09-21 Paul D. Smith <psmith@gnu.org>
1403 * read.c (readstring): Fix some logic errors in backslash handling.
1404 (eval): Remove some unnecessary processing in buffer handling.
1405 (record_target_var): Assert that parse_variable_definition() succeeded.
1406 Reported by: Markus Mauhart <qwe123@chello.at>.
1408 * misc.c: Removed the sindex() function. All instances of this
1409 function were trivially replaceable by the standard strstr()
1410 function, and that function will always have better (or certainly
1411 no worse) performance than the very simple-minded algorithm
1412 sindex() used. This can matter with complex makefiles.
1413 * make.h: Remove the prototype for sindex().
1414 * function.c (subst_expand): Convert sindex() call to strstr().
1415 This means we no longer need to track the TLEN value so remove that.
1416 (func_findstring): Convert sindex() to strstr().
1417 * commands.c (chop_commands): Convert sindex() calls to strstr().
1418 Suggested by: Markus Mauhart <qwe123@chello.at>.
1420 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1421 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1422 If SHELL is set to CMD.EXE then assume it's batch-mode and
1423 non-unixy. I wrote the code differently from the patch, though,
1424 to make it safer. This also resolves bug #9174.
1426 2004-09-20 Paul D. Smith <psmith@gnu.org>
1428 * expand.c (variable_expand_string): Modify to invoke
1429 patsubst_expand() instead of subst_expand(); the latter didn't
1430 handle suffix patterns correctly.
1431 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1432 was used only from variable_expand_string() and is no longer used
1434 (func_subst): Ditto, on call to subst_expand().
1435 (patsubst_expand): Require the percent pointers to point to the
1436 character after the %, not to the % itself.
1437 * read.c (record_files): New call criteria for patsubst_expand().
1438 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1439 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1441 2004-09-19 Paul D. Smith <psmith@gnu.org>
1443 * function.c (subst_expand): Fix a check in by_word: look for a
1444 previous blank if we're beyond the beginning of the string, not
1445 the beginning of the word.
1446 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1448 2004-05-16 Paul D. Smith <psmith@gnu.org>
1450 * remake.c (update_goal_chain): Change the argument specifying
1451 whether we're rebuilding makefiles to be a global variable,
1452 REBUILDING_MAKEFILES.
1453 (complain): Extract the code that complains about no rules to make
1454 a target into a separate function.
1455 (update_file_1): If we tried to rebuild a file during the makefile
1456 rebuild phase and it was dontcare, then no message was printed.
1457 If we then try to build the same file during the normal build,
1458 print a message this time.
1459 (remake_file): Don't complain about un-remake-able files when
1460 we're rebuilding makefiles.
1462 2004-05-11 Paul D. Smith <psmith@gnu.org>
1464 * job.c (construct_command_argv_internal): OS/2 patches from
1465 Andreas Buening <andreas.buening@nexgo.de>.
1467 2004-05-10 Paul D. Smith <psmith@gnu.org>
1469 * remake.c (update_file): Don't walk the double-colon chain unless
1470 this is a double-colon rule. Fix suggested by Boris Kolpackov
1471 <boris@kolpackov.net>.
1473 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1474 * readme.vms: New section describing OpenVMS support and issues.
1475 * default.c (default_variables): Add support for IA64.
1476 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1477 without some privilege aborts make with the error
1478 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1479 pressing Ctrl+Y and the input device is no terminal. The change
1480 catches this error and just continues.
1482 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1484 2004-04-25 Paul D. Smith <psmith@gnu.org>
1486 * commands.c (set_file_variables): Set $< properly in the face of
1487 order-only prerequisites.
1488 Patch from Boris Kolpackov <boris@kolpackov.net>
1490 2004-04-21 Bob Byrnes <byrnes@curl.com>
1492 * main.c (main): Notice failures to remake makefiles.
1494 2004-03-28 Paul D. Smith <psmith@gnu.org>
1496 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1498 * job.c: No default shell for RISC OS.
1499 (load_too_high): Hard-code the return to 1.
1500 (construct_command_argv_internal): No sh_chars or sh_cmds.
1501 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1503 2004-03-20 Paul D. Smith <psmith@gnu.org>
1505 * variable.c (do_variable_definition): Don't append from the
1506 global set if a previous non-appending target-specific variable
1507 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1510 * expand.c (reference_variable): Don't give up on variables with
1511 no value that have the target-specific append flag set: they might
1512 have a value after all. Reported by Oliver Schmidt
1513 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1514 <nikulin@dx1cmd.inp.nsk.su>.
1516 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1517 refer to absolute pathnames in directories that don't exist: some
1518 portion of the makefile could create those directories before we
1519 match the pattern. Fixes bugs #775 and #108.
1521 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1523 * main.c (main): Free makefile_mtimes if we have any.
1524 * README.W32.template: Update documentation for the current status
1525 of the MS-Windows port.
1526 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1527 environment variable is sometimes already defined which causes the
1529 * main.c (debug_signal_handler): Only define this function if
1530 SIGUSR1 is available.
1532 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1534 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1535 * README.OS2.template: Documentation updates.
1536 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1537 link line for safety.
1538 * maintMakefile (build.sh.in): Remove an extraneous ")".
1539 * job.c (child_execute_job): Close saved FDs.
1540 * job.c (exec_command) [OS/2]: exec_command(): If the command
1541 can't be exec'ed and if the shell is not Unix-sh, then try again
1542 with argv = { "cmd", "/c", ... }. Normally, this code is never
1543 reached for the cmd shell unless the command really doesn't exist.
1544 (construct_command_argv_internal) [OS/2]: The code for cmd
1545 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1546 The CMD builtin commands are case insensitive so use strcasecmp().
1548 2004-03-19 Paul D. Smith <psmith@gnu.org>
1550 * read.c (do_define): Re-order line counter increment so the count
1551 is accurate (we were losing one line per define). Reported by
1552 Dave Yost <Dave@Yost.com>.
1554 2004-03-06 Paul D. Smith <psmith@gnu.org>
1556 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1558 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1559 * misc.c (message,error,fatal): Ditto.
1560 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1561 * config.h.W32.template: Ditto.
1562 * config.h-vms.template: Ditto.
1563 * config.ami.template: Ditto.
1565 2004-03-04 Paul D. Smith <psmith@gnu.org>
1567 * README.template: Add a note about broken /bin/sh on SunOS
1568 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1570 * misc.c (message, error, fatal): Don't use "..." if we're using
1571 varargs. ansi2knr should handle this but it doesn't work: it
1572 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1573 done. On many systems (SunOS for example) va_dcl is a #define.
1574 So, force the use of the non-"..." version on pre-ANSI compilers.
1576 * maintMakefile (sign-dist): Create some rules to help automate
1577 the new GNU ftp upload method.
1579 2004-02-24 Paul D. Smith <psmith@gnu.org>
1581 * config.h.W32.template: Add HAVE_STDARG_H
1582 * config.h-vms.template: Ditto.
1583 * config.ami.template: Ditto.
1585 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1587 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1588 * build_w32.bat: Remove extra "+".
1590 2004-02-23 Paul D. Smith <psmith@gnu.org>
1592 * make.h: Create an UNUSED macro to mark unused parameters.
1593 * (many): Clean up warnings by applying UNUSED, fixing
1594 signed/unsigned incompatibilities, etc.
1596 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1598 * filedef.h: Name the command_state enumeration.
1599 * file.c (set_command_state): Use the enumeration in the function
1602 * configure.in: Explicitly set SET_MAKE to empty, to disable
1603 MAKE=make even when no make already exists. Fix bug #3823.
1605 2004-02-22 Paul D. Smith <psmith@gnu.org>
1607 * maintMakefile: Perl script to clean up all non-CVS files. Use
1608 it on all the subdirectories for the cvs-clean target.
1610 * main.c (decode_switches): Require non-empty strings for all our
1611 string command-line options. Fixes Debian bug # 164165.
1613 * configure.in: Check for stdarg.h and varargs.h.
1614 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1615 for printing messages.
1616 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1621 A number of patches for OS/2 support from Andreas Buening
1622 <andreas.buening@nexgo.de>:
1624 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1625 disable the SIGCHLD handler.
1626 (reap_children) [OS/2]: Remove special handling of job_rfd.
1627 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1628 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1629 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1630 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1631 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1634 2004-02-21 Paul D. Smith <psmith@gnu.org>
1636 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1637 <mail@kristov.de> reports that if process_begin() fails we don't
1638 handle the error condition correctly in all cases.
1639 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1640 to have a newline on the message.
1642 * job.c (construct_command_argv_internal): Add "test" to UNIX
1643 sh_cmds[]. Fixes Savannah bug # 7606.
1645 2004-02-04 Paul D. Smith <psmith@gnu.org>
1647 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1648 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1649 Hartmut Becker <Hartmut.Becker@hp.com>.
1651 2004-01-21 Paul D. Smith <psmith@gnu.org>
1653 * job.c (load_too_high): Implement an algorithm to control the
1654 "thundering herd" problem when using -l to control job creation
1655 via the load average. The system only recomputes the load once a
1656 second but we can start many jobs in a second. To solve this we
1657 keep track of the number of jobs started in the last second and
1658 apply a weight to try to guess what a correct load would be.
1659 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1660 Also fixes bug #4693.
1661 (reap_children): Decrease the job count for this second.
1662 (start_job_command): Increase the job count for this second.
1664 * read.c (conditional_line): Expand the text after ifn?def before
1665 checking to see if it's a single word. Fixes bug #7257.
1667 2004-01-09 Paul D. Smith <psmith@gnu.org>
1669 * file.c (print_file): Recurse to print all targets in
1670 double-colon rules. Fixes bug #4518, reported (with patch) by
1671 Andrew Chatham <chatham@google.com>.
1673 2004-01-07 Paul D. Smith <psmith@gnu.org>
1675 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1676 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1677 AC_FUNC_SETVBUF_REVERSED.
1679 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1680 (MAKE Variable): Fix Savannah bug #4898.
1682 * job.c (construct_command_argv_internal): Add "!" to the list of
1683 shell escape chars. POSIX sh allows it to appear before a
1684 command, to negate the exit code. Fixes bug #6404.
1686 * implicit.c (pattern_search): When matching an implicit rule,
1687 remember which dependencies have the ignore_mtime flag set.
1688 Original fix provided in Savannah patch #2349, by Benoit
1689 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1691 2003-11-22 Paul D. Smith <psmith@gnu.org>
1693 * README.W32.template (Outputs): Clarification on -j with
1694 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1697 2003-11-02 Paul D. Smith <psmith@gnu.org>
1699 * function.c (func_if): Strip all the trailing whitespace from the
1700 condition, then don't expand it. Fixed bug # 5798.
1702 * expand.c (recursively_expand_for_file): If we're expanding a
1703 variable with no file context, then use the variable's context.
1706 2003-10-21 Paul D. Smith <psmith@gnu.org>
1708 * main.c (log_working_directory): Add newlines to printf()s.
1710 * README.cvs: Add a note to ignore warnings during autoreconf.
1712 * maintMakefile (po_repo): Set a new URL for PO file updates.
1713 (get-config/config.guess get-config/config.sub): Get these files
1714 from the Savannah config project instead of ftp.gnu.org.
1716 2003-10-05 Paul Eggert <eggert@twinsun.com>
1718 * main.c (main): Avoid potential subscript error if environ has
1721 2003-08-22 Paul D. Smith <psmith@gnu.org>
1723 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1724 systems which don't yet implement the C89 standard :-/.
1726 2003-07-18 Paul D. Smith <psmith@gnu.org>
1728 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1729 [WINDOWS32]: Initialize hash.
1731 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1733 * dir.c (read_dirstream): Provide a workaround for broken versions of
1734 the MinGW dirent structure.
1736 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1738 * w32/include/dirent.h: Add __MINGW32__ filter.
1740 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1742 * make.h: Add global declaration of *make_host.
1743 * main.c (print_usage): Remove local declaration of *make_host.
1744 (print_version): Display "This program built for ..." after Copyright
1747 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1749 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1750 execution of "makeinfo --html make.texi".
1752 2003-04-30 Paul D. Smith <psmith@gnu.org>
1754 * build.template: Make some changes to maybe allow this script to
1755 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1757 * README.OS2.template: New file for OS/2 support. Original
1758 contributed by Andreas Buening.
1759 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1762 2003-04-19 Paul D. Smith <psmith@gnu.org>
1764 Fix bug #1405: allow a target to match multiple pattern-specific
1767 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1768 variable.c, where they've always belonged.
1769 * rule.h: Move the prototypes and struct pattern_var as well.
1770 * variable.c (initialize_file_variables): Invoke
1771 lookup_pattern_var() in a loop, until no more matches are found.
1772 If a match is found, create a new variable set for the target's
1773 pattern variables. Then merge the contents of each matching
1774 pattern variable set into the target's pattern variable set.
1775 (lookup_pattern_var): Change this function to be usable
1776 in a loop. It takes a starting position: if NULL, start at the
1777 beginning; if non-NULL, start with the pattern variable after that
1778 position, and return the next matching pattern.
1779 (create_pattern_var): Create a unique instance of
1780 pattern-specific variables for every definition in the makefile.
1781 Don't combine the same pattern together. This allows us to
1782 process the variable handling properly even when the same pattern
1783 is used multiple times.
1784 (parse_variable_definition): New function: break out the parsing
1785 of a variable definition line from try_variable_definition.
1786 (try_variable_definition): Call parse_variable_definition to
1788 (print_variable_data_base): Print out pattern-specific variables.
1789 * variable.h (struct variable): Remember when a variable is
1790 conditional. Also remember its flavor.
1791 (struct pattern_var): Instead of keeping a variable set, we just
1792 keep a single variable for each pattern.
1793 * read.c (record_target_var): Each pattern variable contains only a
1794 single variable, not a set, so create it properly.
1795 * doc/make.texi (Pattern-specific): Document the new behavior.
1797 2003-04-17 Paul D. Smith <psmith@gnu.org>
1799 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1800 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1801 file/directory naming rules for VMS so I can't tell whether this
1804 2003-04-09 Paul D. Smith <psmith@gnu.org>
1806 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1807 DOS-style pathnames: backslash separators and drive specifiers.
1809 2003-03-28 Paul D. Smith <psmith@gnu.org>
1811 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1812 the intermediate flag on all targets. Fixes bug #2515.
1814 2003-03-24 Paul D. Smith <psmith@gnu.org>
1816 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1817 Upgrade to autoconf 2.57 and automake 1.7.3.
1819 * job.c: More OS/2 changes from Andreas Buening.
1821 * file.c (print_file): Fix variable initialization.
1824 * remake.c (notice_finished_file):
1826 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1827 some calls (like readdir()) return NULL in valid situations
1828 without resetting errno. Fixes bug #2846.
1830 2003-02-25 Paul D. Smith <psmith@gnu.org>
1832 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1834 * job.c (_is_unixy_shell) [OS/2]: New function.
1835 Set default shell to /bin/sh.
1836 (reap_children): Close the job_rfd pipe here since we don't use a
1838 (set_child_handler_action_flags): define this to empty on OS/2.
1839 (start_job_command): Close the jobserver pipe and use
1840 child_execute_job() instead of fork/exec.
1841 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1842 rather than exec'ing, then reconfigure stdin/stdout.
1843 (exec_command): Rewrite to use spawn instead of exec. Return the
1846 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1847 in DOS. Handle the TEMP environment variable as in DOS. Don't
1848 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1849 use -j in DOS mode. Use child_execute_job() instead of
1852 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1855 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1856 prototypes that return values.
1858 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1860 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1861 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1863 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1866 2003-02-24 Paul D. Smith <psmith@gnu.org>
1868 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1869 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1870 (child_execute_job) [VMS]: Handle error status properly.
1871 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1873 * function.c (func_shell): Use EINTRLOOP() while reading from the
1874 subshell pipe (Fixes bug #2502).
1875 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1877 * main.c (main): Ditto.
1879 2003-01-30 Paul D. Smith <psmith@gnu.org>
1881 * read.c (eval): eval() was not fully reentrant, because the
1882 collapsed buffer was static. Change it to be an automatic
1883 variable so that eval() can be invoked recursively.
1885 (eval): Apply patch # 1022: fix memory reference error on long
1886 target-specific variable lines.
1887 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1889 * function.c (check_numeric): Combine the is_numeric() function
1890 into this function, since it's only called from one place.
1891 Constify this function. Have it print the incorrect string in the
1892 error message. Fixes bug #2407.
1893 (strip_whitespace): Constify.
1894 (func_if): Constify.
1895 * expand.c (expand_argument): Constify.
1897 2003-01-29 Paul D. Smith <psmith@gnu.org>
1899 Fix bug # 2169, also reported by other people on various systems.
1901 * make.h: Some systems, such as Solaris and PTX, do not fully
1902 implement POSIX-compliant SA_RESTART functionality; important
1903 system calls like stat() and readdir() can still fail with EINTR
1904 even if SA_RESTART has been set on the signal handler. So,
1905 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1906 EINTR for system calls which return -1 or 0 (NULL), respectively,
1908 Also, remove the old atomic_stat()/atomic_readdir() and
1909 HAVE_BROKEN_RESTART handling.
1911 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1913 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1914 * remake.c (touch_file): Ditto.
1916 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1917 * read.c (construct_include_path): Ditto.
1918 * remake.c (name_mtime): Ditto.
1919 * vpath.c (selective_vpath_search): Ditto.
1920 * dir.c (find_directory): Ditto.
1921 (local_stat): Ditto.
1922 (find_directory): Use ENULLLOOP() to wrap opendir().
1923 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1925 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1926 atomic_readdir() handling.
1928 2003-01-22 Paul D. Smith <psmith@gnu.org>
1930 * function.c (func_call): Fix Bug #1744. If we're inside a
1931 recursive invocation of $(call ...), mask any of the outer
1932 invocation's arguments that aren't used by this one, so that this
1933 invocation doesn't "inherit" them accidentally.
1935 2002-12-05 Paul D. Smith <psmith@gnu.org>
1937 * function.c (subst_expand): Valery Khamenia reported a
1938 pathological performance hit when doing substitutions on very
1939 large values with lots of words: turns out we were invoking
1940 strlen() a ridiculous number of times. Instead of having each
1941 call to sindex() call strlen() again, keep track of how much of
1942 the text we've seen and pass the length to sindex().
1944 2002-11-19 Paul D. Smith <psmith@gnu.org>
1946 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1949 2002-11-16 Paul D. Smith <psmith@gnu.org>
1951 * NMakefile.template (OBJS): Add hash.c object file.
1952 * SMakefile.template (srcs): Ditto.
1953 * Makefile.ami (objs): Ditto.
1954 * build_w32.bat: Ditto.
1956 * Makefile.DOS.template: Remove extra dependencies.
1958 2002-10-25 Paul D. Smith <psmith@gnu.org>
1960 * expand.c (install_variable_buffer): New function. Install a new
1961 variable_buffer context and return the previous one.
1962 (restore_variable_buffer): New function. Free the current
1963 variable_buffer context and put a previously saved one back.
1964 * variable.h: Prototypes for {install,restore}_variable_buffer.
1965 * function.c (func_eval): Push a new variable_buffer context
1966 before we eval, then restore the old one when we're done.
1969 * read.c (install_conditionals): New function. Install a new
1970 conditional context and return the previous one.
1971 (restore_conditionals): New function. Free the current
1972 conditional context and put a previously saved one back.
1973 (eval): Use the {install,restore}_conditionals for "include"
1975 (eval_buffer): Use {install,restore}_conditionals to preserve the
1976 present conditional state before we evaluate the buffer.
1979 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1981 (Recursion): Add a variable index entry for CURDIR.
1983 * README.cvs: Update to appropriate versions.
1984 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1985 don't need to copy loadavg.c: automake is smart enough to create
1986 it for me. Still have a bug in automake related to ansi2knr tho.
1988 2002-10-14 Paul D. Smith <psmith@gnu.org>
1990 * remake.c (notice_finished_file): Only touch targets if they have
1991 at least one command (as per POSIX). Resolve Bug #1418.
1993 * *.c: Convert to using ANSI C-style function definitions.
1994 * Makefile.am: Enable the ansi2knr feature of automake.
1995 * configure.in: ditto.
1997 2002-10-13 Paul D. Smith <psmith@gnu.org>
1999 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2000 for automatic variable values like $^, etc. In the case of very
2001 large lists of prerequisites this causes problems. Instead reuse
2002 a static buffer (resizeable) for each variable.
2004 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2005 target-specific variable definitions. Check for it and set an
2007 (record_target_var): Set the export field to v_export if the
2008 "exported" flag is set.
2009 * doc/make.texi (Target-specific): Document the ability to use
2012 * doc/make.texi: Change the name of the section on automatic
2013 variables from "Automatic" to "Automatic Variables". Added text
2014 clarifying the scope of automatic variables.
2016 2002-10-04 Paul D. Smith <psmith@gnu.org>
2018 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2020 (record_files): Ditto.
2022 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2023 the search for the '=' to only within the enclosing parens.
2025 2002-10-03 Paul D. Smith <psmith@gnu.org>
2027 Version 3.80 released.
2029 * dir.c: Change hash functions to use K&R function definition style.
2030 * function.c: Ditto.
2032 * variable.c: Ditto.
2034 Update to automake 1.7.
2036 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2037 (pdf): Remove this target as automake now provides one.
2039 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2041 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2043 * makefile.com: Updates for GNU make 3.80.
2044 * makefile.vms: Ditto.
2046 2002-09-23 Paul D. Smith <psmith@gnu.org>
2048 * read.c (enum make_word_type): Remove w_comment.
2049 (get_next_mword): Don't treat comment characters as special; where
2050 this function is used we will never see a comment (it's stripped
2051 before we get here) and treating comments specially means that
2052 targets like "foo\#bar" aren't handled properly.
2054 2002-09-18 Paul D. Smith <psmith@gnu.org>
2056 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2058 * read.c (eval): Expansion of arguments to export/unexport was
2059 ignoring all arguments after the first one. Change the algorithm
2060 to expand the whole line once, then parse the results.
2062 2002-09-17 Paul D. Smith <psmith@gnu.org>
2064 Fix Bug #940 (plus another bug I found while looking at this):
2066 * read.c (record_target_var): enter_file() will add a new entry if
2067 it's a double-colon target: we don't want to do that in this
2068 situation. Invoke lookup_file() and only enter_file() if it does
2069 not already exist. If the file we get back is a double-colon then
2070 add this variable to the "root" double-colon target.
2072 * variable.c (initialize_file_variables): If this file is a
2073 double-colon target but is not the "root" target, then initialize
2074 the root and make the root's variable list the parent of our
2077 2002-09-13 Paul D. Smith <psmith@gnu.org>
2079 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2081 * hash.c (round_up_2): Get rid of a warning.
2083 2002-09-12 Paul D. Smith <psmith@gnu.org>
2085 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2086 so it doesn't complain about getloadavg.c.
2088 * commands.c (set_file_variables): Make sure we always alloca() at
2089 least 1 character for the value of $? (for '\0').
2091 2002-09-11 Paul D. Smith <psmith@gnu.org>
2093 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2094 macro to use RESULT instead of the incorrect _RESULT_.
2096 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2097 and atomic_readdir(). We need to #include dirent.h to get this to
2099 * misc.c (atomic_readdir): Fix typos.
2101 2002-09-10 Paul D. Smith <psmith@gnu.org>
2103 * read.c (eval): Expand variable lists given to export and
2104 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2105 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2107 * doc/make.texi (Variables/Recursion): Document this.
2108 (Conditional Syntax): And here.
2110 2002-09-09 Paul D. Smith <psmith@gnu.org>
2112 * configure.in: Check for memmove().
2114 2002-09-07 Paul D. Smith <psmith@gnu.org>
2116 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2117 Michael Sterrett <msterret@coat.com> reports that while it has
2118 SA_RESTART, it does not work properly.
2120 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2121 that invokes stat() and loops to do it again if it returns EINTR.
2122 (atomic_readdir): Ditto, with readdir().
2124 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2125 and readdir() to atomic_stat() and atomic_readdir().
2127 2002-09-04 Paul D. Smith <psmith@gnu.org>
2129 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2130 reports that GNU make sometimes doesn't recognize that targets can
2131 be made, when directories can be created as prerequisites. He
2132 reports that changing the order of predicates in the DEP->changed
2133 flag test so that lookup_file() is always performed, solves this
2136 2002-08-08 Paul D. Smith <psmith@gnu.org>
2138 * configure.in: Require a newer version of gettext.
2140 * misc.c (perror_with_name): Translate the format string (for
2141 right-to-left language support).
2142 (pfatal_with_name): Ditto.
2144 * main.c: Create a static array of strings to store the usage
2145 text. This is done to facilitate translations.
2146 (struct command_switch): Remove argdesc and description fields.
2147 (switches): Remove values for obsolete fields.
2148 (print_usage): Print each element of the usage array.
2150 * hash.c: Change function definitions to be K&R style.
2152 2002-08-02 Paul D. Smith <psmith@gnu.org>
2154 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2155 this one because it's too hard to get right. We'll look at it for
2157 * main.c (main): Don't create the .TARGETS variable.
2158 * variable.c (handle_special_var): Don't handle .TARGETS.
2160 2002-08-01 Paul D. Smith <psmith@gnu.org>

2164 if they don't appear to be out of date.
2165 (always_make_flag): New flag.
2166 * make.h: Extern always_make_flag.
2167 * remake.c (update_file_1): Check always_make_flag; if it's set we
2168 will always rebuild any target we can, even if none of its
2169 prerequisites are newer.
2172 * doc/make.texi (Shell Function): Make it clear that make
2173 variables marked as "export" are not passed to instances of the
2176 Add new introspection variable .VARIABLES and .TARGETS.
2178 * variable.c (handle_special_var): New function. If the variable
2179 reference passed in is "special" (.VARIABLES or .TARGETS),
2180 calculate the new value if necessary. .VARIABLES is handled here:
2181 walk through the hash of defined variables and construct a value
2182 which is a list of the names. .TARGETS is handled by
2183 build_target_list().
2184 (lookup_variable): Invoke handle_special_var().
2185 * file.c (build_target_list): Walk through the hask of known files
2186 and construct a list of the names of all the ones marked as
2188 * main.c (main): Initialize them to empty (and as simple variables).
2189 * doc/make.texi (Special Variables): Document them.
2190 * NEWS: Mention them.
2192 * variable.h (struct variable): Add a new flag "exportable" which
2193 is true if the variable name is valid for export.
2194 * variable.c (define_variable_in_set): Set "exportable" when a new
2195 variable is defined.
2196 (target_environment): Use the "exportable" flag instead of
2197 re-checking the name here... an efficiency improvement.
2199 2002-07-31 Paul D. Smith <psmith@gnu.org>
2201 * config.h-vms.template: Updates to build on VMS. Thanks to
2202 Brian_Benning@aksteel.com for helping verify the build.
2203 * makefile.com: Build the new hash.c file.
2204 * hash.h: Use strcpmi(), not stricmp(), in the
2205 HAVE_CASE_INSENSITIVE_FS case.
2207 2002-07-30 Paul D. Smith <psmith@gnu.org>
2209 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2210 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2211 Reported by <Brian_Benning@aksteel.com>.
2213 2002-07-10 Paul D. Smith <psmith@gnu.org>
2215 * variable.c (pop_variable_scope): Remove variable made unused by
2216 new hash infrastructure.
2217 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2218 comparisons as well as name comparisons.
2219 * variable.h: Add a prototype for new hash_init_function_table().
2220 * file.c (lookup_file): Remove variables made unused by new hash
2222 * dir.c (directory_contents_hash_2): Missing return of hash value.
2223 (dir_contents_file_exists_p): Remove variables made unused by new
2224 hash infrastructure.
2227 Installed Greg McGary's integration of the hash functions from the
2228 GNU id-utils package:
2230 2002-07-10 Greg McGary <greg@mcgary.org>
2232 * scripts/functions/filter-out: Add literals to to the
2233 pattern space in order to add complexity, and trigger
2234 use of an internal hash table. Fix documentation strings.
2235 * scripts/targets/INTERMEDIATE: Reverse order of files
2236 passed to expected `rm' command.
2238 2002-07-10 Greg McGary <greg@mcgary.org>

2310 (find_char_unquote): Accept two char-constant stop chars, rather
2311 than a string constant, avoiding zillions of calls to strchr.
2312 Tighten inner search loops to test only for desired delimiters.

2330 2002-07-10 Paul D. Smith <psmith@gnu.org>
2332 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2333 prerequisite list. A real SysV make will expand the entire
2334 prerequisites list _twice_: we don't do that as it's a big
2335 backward-compatibility problem. We only replace those specific
2338 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2339 references left in the list of prerequisites. Check for .POSIX as
2340 we record targets, so we can disable non-POSIX behavior while
2341 reading makefiles as well as running them.
2342 (eval): Check the prerequisite list to see if we have anything
2343 that looks like a SysV prerequisite variable reference.
2345 2002-07-09 Paul D. Smith <psmith@gnu.org>
2347 * doc/make.texi (Prerequisite Types): Add a new section describing
2348 order-only prerequisites.
2350 * read.c (uniquize_deps): If we have the same file as both a
2351 normal and order-only prereq, get rid of the order-only prereq,
2352 since the normal one supersedes it.
2354 2002-07-08 Paul D. Smith <psmith@gnu.org>
2356 * AUTHORS: Added Greg McGary to the AUTHORS file.
2357 * NEWS: Blurbed order-only prerequisites.
2358 * file.c (print_file): Show order-only deps properly when printing
2361 * maintMakefile: Add "update" targets for wget'ing the latest
2362 versions of various external files. Taken from Makefile.maint in
2365 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2366 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2368 2002-07-07 Paul D. Smith <psmith@gnu.org>
2370 * po/*.po: Remove. We'll use wget to retrieve them at release
2373 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2374 rather than a shell you get an exception. Make sure we look up
2375 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2377 * remake.c (notice_finished_file): Fix handling of -t flag.
2378 Patch provided by Henning Makholm <henning@makholm.net>.
2380 * implicit.c (pattern_search): Some systems apparently run short
2381 of stack space, and using alloca() in this function caused an
2382 overrun. I modified it to use xmalloc() on the two variables
2383 which seemed like they might get large. Fixes Bug #476.
2385 * main.c (print_version): Update copyright notice to conform with
2387 (print_usage): Update help output.
2389 * function.c (func_eval): Create a new make function, $(eval
2390 ...). Expand the arguments, put them into a buffer, then invoke
2391 eval_buffer() on the resulting string.
2392 (func_quote): Create a new function, $(quote VARNAME). Inserts
2393 the value of the variable VARNAME without expanding it any
2396 * read.c (struct ebuffer): Change the linebuffer structure to an
2397 "eval buffer", which can be either a file or a buffer.
2398 (eval_makefile): Move the code in the old read_makefile() which
2399 located a makefile into here: create a struct ebuffer with that
2400 information. Have it invoke the new function eval() with that
2402 (eval_buffer): Create a new function that creates a struct ebuffer
2403 that holds a string buffer instead of a file. Have it invoke
2404 eval() with that ebuffer.
2405 (eval): New function that contains the guts of the old
2406 read_makefile() function: this function parses makefiles. Obtains
2407 data to parse from the provided ebuffer. Some modifications to
2408 make the flow of the function cleaner and clearer. Still could
2409 use some work here...
2410 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2411 contents of the define/endef variable from the ebuffer.
2412 (readstring): Read the next line from a string-style ebuffer.
2413 (readline): Read the next line from an ebuffer. If it's a string
2414 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2417 * dep.h (eval_buffer): Prototype eval_buffer();
2419 * variable.c (do_variable_definition): Make sure that all
2420 non-target-specific variables are registered in the global set.
2421 If we're invoked from an $(eval ...) we might be inside a $(call
2422 ...) or other function which has pushed a variable scope; we still
2423 want to define our variables from evaluated makefile code in the
2426 2002-07-03 Greg McGary <greg@mcgary.org>
2428 * dep.h (struct dep) [ignore_mtime]: New member.
2429 [changed]: convert to a bitfield.
2430 * implicit.c (pattern_search): Zero ignore_mtime.
2431 * main.c (main, handle_non_switch_argument): Likewise.
2432 * rule.c (convert_suffix_rule): Likewise.
2433 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2434 (read_makefile): Parse '|' in prerequisite list.
2435 (uniquize_deps): Consider ignore_mtime when comparing deps.
2436 * remake.c (update_file_1, check_dep): Don't force remake for
2437 dependencies that have d->ignore_mtime.
2438 * commands.c (FILE_LIST_SEPARATOR): New constant.
2439 (set_file_variables): Don't include a
2440 prerequisite in $+, $^ or $? if d->ignore_mtime.
2443 2002-06-18 Paul D. Smith <psmith@gnu.org>
2445 * make.texinfo: Updates for next revision. New date/rev/etc.
2446 Recreate all Info menus. Change license on the manual to the GNU
2447 Free Documentation License. A number of typos.
2448 (Variables Simplify): Don't use "-" before it's defined.
2449 (Automatic Prerequisites): Rewrite the target example to work
2450 properly if the compile fails. Remove incorrect comments about
2451 how "set -e" behaves.
2452 (Text Functions): Move the "word", "wordlist", "words", and
2453 "firstword" functions here, from "File Name Functions".
2454 * make-stds.texi: Update from latest GNU version.
2455 * fdl.texi: (created) Import the latest GNU version.
2457 2002-06-06 Paul D. Smith <psmith@gnu.org>
2459 * variable.c (do_variable_definition): New function: extract the
2460 part of try_variable_definition() that actually sets the value
2461 into a separate function.
2462 (try_variable_definition): Call do_variable_definition() after
2463 parsing the variable definition string.
2464 (define_variable_in_set): Make the name argument const.
2466 * variable.h (enum variable_flavor): Make public.
2467 (do_variable_definition): Create prototype.
2469 * read.c (read_all_makefiles): Create a new built-in variable,
2471 (read_makefile): Add each makefile read in to this variable value.
2473 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2475 * Makefile.DOS.template: Tweak according to changes in the
2476 distribution. Add back the dependencies of *.o files.
2478 * configh.dos.template: Synchronize with config.h.in.
2480 2002-05-09 Paul D. Smith <psmith@gnu.org>
2482 * file.c (file_timestamp_now): Use K&R function declaration.
2484 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2485 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2486 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2487 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2488 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2489 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2490 nlist.n_name is a pointer rather than an array.
2492 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2493 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2494 * configure.in: Use it instead of the old version.
2496 * main.c (main): Prefer setvbuf() to setlinebuf().
2498 2002-05-08 Paul D. Smith <psmith@gnu.org>
2500 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2501 (loadavg_LDADD): Ditto.
2503 2002-04-29 Paul D. Smith <psmith@gnu.org>
2505 * expand.c (recursively_expand_for_file): Rename
2506 recursively_expand() to recursively_expand_for_file() and provide
2507 an extra argument, struct file. If the argument is provided, set
2508 the variable scope to that of the file before expanding.
2509 * variable.h (recursively_expand): Make this a macro that invokes
2510 recursively_expand_for_file() with a NULL file pointer.
2511 * variable.c (target_environment): Call the renamed function and
2512 provide the current file context.
2513 Fixes Debian bug #144306.
2515 2002-04-28 Paul D. Smith <psmith@gnu.org>
2517 Allow $(call ...) user-defined variables to be self-referencing
2518 without throwing an error. Allows implementation of transitive
2519 closures, among other possibly useful things.
2520 Requested by: Philip Guenther <guenther@sendmail.com>
2522 * variable.h (struct variable): Add a new field: exp_count, and
2523 new macros to hold its size and maximum value.
2524 (warn_undefined): Make this a macro.
2525 * variable.c (define_variable_in_set): Initialize it.
2526 * expand.c (recursively_expand): If we detect recursive expansion
2527 of a variable, check the exp_count field. If it's greater than 0
2528 allow the recursion and decrement the count.
2529 (warn_undefined): Remove this (now a macro in variable.h).
2530 * function.c (func_call): Before we expand the user-defined
2531 function, modify its exp_count field to contain the maximum
2532 number of recursive calls we'll allow. After the call, reset it
2535 2002-04-21 Paul D. Smith <psmith@gnu.org>
2537 Modified to use latest autoconf (2.53), automake (1.6.1), and
2538 gettext (0.11.1). We're using gettext's new "external" support,
2539 to avoid including libintl source with GNU make.
2541 * README.cvs: New file. Explain how to build GNU make from CVS.
2543 * configure.in: Modify checking for the system glob library.
2544 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2545 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2546 etc. will manage it correctly). Set an automake conditional
2547 USE_LOCAL_GLOB to decide whether to compile the glob library.
2549 * getloadavg.c (main): Include make.h in the "TEST" program to
2552 * Makefile.am: Remove special rules for loadavg. Replace them
2553 with Automake capabilities for building extra programs.
2555 * signame.c: This file does nothing if the system provide
2556 strsignal(). If not, it implements strsignal(). If the system
2557 doesn't define sys_siglist, then we make our own; otherwise we use
2559 * signame.h: Removed.
2561 * main.c (main): No need to invoke signame_init(). Update copyright.
2563 * ABOUT-NLS: Removed.
2564 * gettext.c: Removed.
2565 * gettext.h: Get a simplified copy from the gettext package.
2567 * i18n/*.po: Moved to po/.
2570 * config/*: Created. Contains package configuration helper files.
2571 * config.guess, config.sub: Moved to config directory.
2573 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2574 Rework to use new-style autoconf features. Use the "external"
2575 mode for gettext. Make the build.sh config file conditional on
2576 whether build.sh.in exists, to avoid autoconf errors.
2577 * acinclude.m4: Removed almost all macros as being obsolete.
2578 Rewrote remaining macros to use AC_DEFINE.
2579 * acconfig.h: Removed.
2581 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2582 conditional to handle customs support. Remove special handling
2585 2002-04-20 Paul D. Smith <psmith@gnu.org>
2587 * function.c (func_call): Don't mark the argument variables $1,
2588 etc. as recursive. They've already been fully expanded so
2589 there's no need to do it again, and doing so strips escaped $'s.
2590 Reported by Sebastian Glita <glseba@yahoo.com>.
2592 * remake.c (notice_finished_file): Walk through double-colon
2593 entries via the prev field, not the next field!
2594 Reported by Greg McGary <greg@mcgary.org>.
2596 * main.c (main): If the user specifies -q and asks for a specific
2597 target which is a makefile, we got an assert. In that case it
2598 turns out we should continue normally instead.
2600 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2602 * i18n/he.po: Installed a new translation.
2604 2002-01-07 Paul D. Smith <psmith@gnu.org>
2606 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2608 2001-12-04 Paul D. Smith <psmith@gnu.org>
2610 * i18n/ja.po: Installed an updated translation.
2612 2001-09-06 Paul Eggert <eggert@twinsun.com>
2614 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2615 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2617 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2619 (main): Get rid of any avoidable limit on stack size.
2621 2001-09-04 Paul D. Smith <psmith@gnu.org>
2623 * i18n/da.po: Installed an updated translation.
2625 2001-08-03 Paul D. Smith <psmith@gnu.org>
2627 * i18n/fr.po: Installed an updated translation.
2628 Resolves Debian bug #106720.
2630 2001-06-13 Paul D. Smith <psmith@gnu.org>
2632 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2635 2001-06-11 Paul D. Smith <psmith@gnu.org>
2637 * i18n/ko.po: Installed a new translation.
2639 2001-05-06 Paul D. Smith <psmith@gnu.org>
2641 Modify the EINTR handling.
2643 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2644 the way in which we manage the file descriptor/signal handler race
2645 trap to be more efficient.
2647 2001-05-06 Paul Eggert <eggert@twinsun.com>
2649 Restart almost all system calls that are interrupted, instead
2650 of worrying about EINTR. The lone exception is the read() for
2653 * configure.in (HAVE_SA_RESTART): New macro.
2654 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2655 * main.c (main): Use SA_RESTART instead of the old,
2656 nonstandard SA_INTERRUPT.
2658 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2659 * main.c (bsd_signal): New function or macro,
2660 if the implementation doesn't supply it.
2661 (The bsd_signal function will be in POSIX 1003.1-200x.)
2662 (HANDLESIG): Remove.
2663 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2665 * make.h (EINTR_SET): Remove.
2666 (SA_RESTART): New macro.
2668 * arscan.c (ar_member_touch): Don't worry about EINTR.
2669 * function.c (func_shell): Likewise.
2670 * job.c (reap_children, free_child, new_job): Likewise.
2671 * main.c (main): Likewise.
2672 * remake.c (touch_file, name_mtime): Likewise.
2674 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2675 if fstat failed with errno!=EINTR, the error was ignored.
2677 * job.c (set_child_handler_action_flags): New function.
2678 (new_job): Use it to temporarily clear the SIGCHLD action flags
2679 while reading the token.
2681 2001-05-02 Paul D. Smith <psmith@gnu.org>
2683 * job.c (start_job_command): Don't add define/endef per-line flags
2684 to the top-level flags setting.
2686 2001-04-03 Paul D. Smith <psmith@gnu.org>
2688 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2689 bit on error, so check for odd return values, not non-0 return
2691 (VMS_get_member_info): Calculate the timezone differences correctly.
2692 Reported by John Fowler <jfowler@nyx.net>.
2695 2001-03-14 Paul D. Smith <psmith@gnu.org>
2697 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2698 value before invoking define_variable().
2699 Reported by John Fowler <jfowler@nyx.net>.
2701 2001-02-07 Paul D. Smith <psmith@gnu.org>
2703 * read.c (record_target_var): If we reset the variable due to a
2704 command-line variable setting overriding it, turn off the "append"
2707 2001-01-17 Paul D. Smith <psmith@gnu.org>
2709 * variable.c (lookup_variable) [VMS]: When getting values from the
2710 environment, allocate enough space for the _value_ plus escapes,
2711 not enough space for the name plus escapes :-/.
2712 Reported by John Fowler <jfowler@nyx.net>.
2714 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2715 warnings that make generates, so it doesn't look like an error.
2716 Reported by Karl Berry <karl@gnu.org>.
2719 Fix for PR/2020: Rework appended target-specific variables. I'm
2720 fairly confident this algorithm is finally correct.
2722 * expand.c (allocated_variable_append): Rewrite. Instead of
2723 expanding each appended variable then adding all the expanded
2724 strings together, we append all the unexpanded values going up
2725 through the variable set contexts, then expand the final result.
2726 This behaves just like non-target-specific appended variable
2727 values, while the old way didn't in various corner cases.
2728 (variable_append): New function: recursively append the unexpanded
2729 value of a variable, walking from the outermost variable scope to
2731 * variable.c (lookup_variable): Remove the code that looked up the
2732 variable set list if the found variable was "append". We don't
2734 (lookup_variable_in_set): Make this non-static so we can use it
2736 (try_variable_definition): Use lookup_variable_in_set() rather
2737 than faking out current_variable_set_list by hand (cleanup).
2738 * variable.h: Add a prototype for the now non-static
2739 lookup_variable_in_set().
2741 2000-11-17 Paul D. Smith <psmith@gnu.org>
2743 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2744 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2745 before throwing a fit.
2747 2000-11-17 Paul D. Smith <psmith@gnu.org>
2749 * read.c (readline): CRLF calculations had a hole, if you hit the
2750 buffer grow scenario just right. Reworked the algorithm to avoid
2751 the need for len or lastlen at all. Problem description with
2752 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2754 2000-10-24 Paul D. Smith <psmith@gnu.org>
2756 * gettext.c (SWAP): Declare this with the prototype, otherwise
2757 some systems don't work (non-32-bit? Reported for Cray T3E).
2758 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2760 2000-10-05 Paul D. Smith <psmith@gnu.org>
2762 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2763 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2765 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2767 2000-09-22 Paul D. Smith <psmith@gnu.org>
2769 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2770 parts of the real gettext.h here, and we expect to really include
2771 the real gettext.h later. If we keep this #define, it's ignored.
2773 2000-09-21 Paul D. Smith <psmith@gnu.org>
2775 * main.c (log_working_directory): Rework the text to use complete
2776 sentences, to make life simpler for the translators.
2778 2000-08-29 Paul D. Smith <psmith@gnu.org>
2780 * file.c (remove_intermediates): Print a debug message before we
2781 remove intermediate files, so the user (if she uses -d) knows
2784 2000-08-21 Paul D. Smith <psmith@gnu.org>
2786 * variable.c (try_variable_definition): Change how we handle
2787 target-specific append variable defns: instead of just setting the
2788 value, expand it as an append _but_ only within the current
2789 target's context. Otherwise we lose all but the last value if the
2790 variable is appended more than once within the current target
2791 context. Fixes PR/1831.
2793 2000-08-16 Paul D. Smith <psmith@gnu.org>
2795 * function.c (func_shell): Nul-terminate the buffer before
2796 printing an exec error message (just in case it's not!).
2797 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2799 2000-07-25 Paul D. Smith <psmith@gnu.org>
2801 * job.c (construct_command_argv_internal): Add "~" to the list of
2802 sh_chars[] which disallow optimizing out the shell call.
2804 2000-07-23 Paul Eggert <eggert@twinsun.com>
2806 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2807 supersedes --disable-nsec-timestamps.
2808 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2809 * README: Remove --disable-nsec-timestamps.
2811 * filedef.h (struct file.low_resolution_time): New member.
2812 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2813 * remake.c (update_file_1):
2814 Avoid spurious rebuilds due to low resolution time stamps,
2815 generalizing the earlier code that applied only to archive members.
2816 (f_mtime): Archive members always have low resolution time stamps.
2818 * configure.in: Remove --disable-nsec-timestamps, as this has
2819 been superseded by .LOW_RESOLUTION_TIME.
2821 2000-07-23 Paul Eggert <eggert@twinsun.com>
2823 * configure.in (enable_nsec_timestamps): Renamed from
2824 make_cv_nsec_timestamps, since enable/disable options
2825 shouldn't be cached.
2827 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2828 and Paul Eggert <eggert@twinsun.com>
2830 * file.c (file_timestamp_now):
2831 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2832 so that clock_gettime is not linked unless needed.
2834 * filedef.h (FILE_TIMESTAMP_HI_RES):
2835 Remove definition; "configure" now does this.
2837 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2838 to before high resolution file timestamp check,
2839 since that check now uses uintmax_t.
2840 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2841 high resolution file timestamps.
2842 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2843 so that we don't link in clock_gettime unnecessarily.
2845 2000-07-17 Paul D. Smith <psmith@gnu.org>
2847 * i18n/ja.po: New version of the translation file.
2849 2000-07-07 Paul D. Smith <psmith@gnu.org>
2851 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2852 the offset calculation.
2853 (name_mtime): Replace EINTR test with EINTR_SET macro.
2855 2000-07-07 Paul Eggert <eggert@twinsun.com>
2859 * remake.c (update_file_1):
2860 Avoid spurious rebuilds of archive members due to their
2861 timestamp resolution being only one second.
2862 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2863 the clock's resolution being lower than file timestamps'.
2864 When warning about future timestamps, report only the discrepancy,
2865 not the absolute value of the timestamp and the current time.
2867 * file.c (file_timestamp_now): New arg RESOLUTION.
2868 * filedef.h (file_timestamp_now): Likewise.
2869 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2871 2000-07-05 Paul D. Smith <psmith@gnu.org>
2873 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2874 to listp. Fixes PR/1793.
2876 2000-06-26 Paul Eggert <eggert@twinsun.com>
2878 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2880 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2882 * remake.c (f_mtime): Remove unused var memtime.
2884 2000-06-25 Martin Buchholz <martin@xemacs.org>
2886 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2887 Ran spell-check on make.texinfo.
2889 2000-06-23 Paul D. Smith <psmith@gnu.org>
2891 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2892 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2893 * make.h: Define these macros.
2895 * Version 3.79.1 released.
2897 * configure.in: Add a new option, --disable-nsec-timestamps, to
2898 avoid using sub-second timestamps on systems that support it. It
2899 can lead to problems, e.g. if your makefile relies on "cp -p".
2900 * README.template: Document the issue with "cp -p".
2902 * config.guess, config.sub: Updated.
