84 Dave Korn <dave.korn@artimi.com>
86 2007-05-08 Paul Smith <psmith@gnu.org>
88 Fix Savannah bug #19656:
90 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
92 * make.h: Change all case-insensitive string compares to use
93 strcasecmp() (from POSIX). If we don't have that but do have one
94 of the others, define strcasecmp to be one of those instead. If
95 we don't have any, declare a prototype for our own version.
97 * misc.c (strcasecmp): Use this if we can't find any native
98 case-insensitive string comparison function.
99 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
100 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
102 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
103 strcasecmp() instead of stricmp().
104 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
105 instead of strcmpi().
106 * acinclude.m4: Remove the strcasecmp() check from here.
108 2007-03-21 Paul Smith <psmith@gnu.org>
110 * configure.in: Don't turn on case-insensitive file system support
111 if --disable-... is given. Fixes Savannah bug #19348.
113 2007-03-19 Paul Smith <psmith@gnu.org>
115 * ALL: Use the strcache for all file name strings, or other
116 strings which we will never free. The goal is to save memory by
117 avoiding duplicate copies of strings. However, at the moment this
118 doesn't save much memory in most situations: due to secondary
119 expansion we actually save prerequisite lists twice (once before
120 the secondary expansion, and then again after it's been parsed
121 into individual file names in the dep list). We will resolve this
122 in a future change, by doing the parsing up-front for targets
123 where secondary expansion is not set.
125 Moving things into the strcache also allows us to use const
126 pointers in many more places.
128 2007-01-03 Paul Smith <psmith@gnu.org>
130 * make.h (ENULLLOOP): Reset errno after each failed invocation of
131 the function, not just the first. Fixes Savannah bug #18680.
133 2006-11-18 Paul Smith <psmith@gnu.org>
135 * strcache.c (strcache_add_len): Don't allocate a new buffer
136 unless the string is not already nil-terminated. Technically this
137 is a violation of the standard, since we may be passed an array
138 that is not long enough to test one past. However, in make this
139 is never true since we only use nil-terminated strings or
142 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
144 * main.c: New global cmd_prefix, defaults to '\t'.
145 * job.c (construct_command_argv_internal): Use cmd_prefix instead
149 (dir_contents_file_exists_p): Check for an error return from
150 readdir(), just in case.
152 * commands.c: Constified.
153 * default.c: Constified.
154 * expand.c: Constified.
155 * function.c: Partial constification.
156 * variable.c: Partial constification.
157 * vmsify.c: Constification. Hard to test this but I hope I didn't

162 2006-11-16 Eli Zaretskii <eliz@gnu.org>
164 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
165 backslashes and drive letters as absolute.
167 2006-10-22 Paul Smith <psmith@gnu.org>
169 * main.c (struct command_switch): Use const and void*.
171 2006-10-21 Paul Smith <psmith@gnu.org>
174 * arscan.c: Constified.
176 2006-09-30 Paul Smith <psmith@gnu.org>
178 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
179 point to lastword since the example was updated.
180 Fixes Savannah bug #16304.
181 (Secondary Expansion): Correct example description.
182 Fixes Savannah bug #16468.
183 (Makefile Contents): Clarify that comments cannot appear within
184 variable references or function calls.
185 Fixes Savannah bug #16577.
186 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
187 Fixes Savannah bug #17701.
188 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

236 2006-04-20 Paul D. Smith <psmith@gnu.org>
238 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
239 that don't have extended grep.
240 (cvsclean): Use $(PERL) instead of perl.
242 2006-04-09 Paul D. Smith <psmith@gnu.org>

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

308 Declare and define sh_chars_sh[].
310 2006-03-23 Paul D. Smith <psmith@gnu.org>
312 * configure.in: Look for build.sh.in in $srcdir so it will be
313 built for remote configurations as well.

316 Fixes Savannah bug #16166.
318 * misc.c (log_access): Takes a const char *.

369 (allocated_variable_append): Don't expand the final result.
370 Fixes Savannah bug #15913.
372 2006-03-09 Paul Smith <psmith@gnu.org>
374 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
375 listed non-existent files as changed. Turns out there's a bug in
376 the Linux kernel builds which means that this change causes
377 everything to rebuild every time. We will re-introduce this fix
378 in the next release, to give them time to fix their build system.
379 Fixes Savannah bug #16002.
380 Introduces Savannah bug #16051.
382 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

399 * commands.c (set_file_variables): Realloc, not malloc, the static
400 string values to avoid memory leaks.
402 * expand.c (recursively_expand_for_file): Only set reading_file to
403 an initialized value.
405 * implicit.c (pattern_search): We need to make a copy of the stem
406 if we get it from an intermediate dep, since those get freed.

417 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
418 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
419 the calls to _beginthreadex.
421 * expand.c (recursively_expand_for_file): Initialize `save' to
422 prevent compiler warnings.
424 2006-02-18 Eli Zaretskii <eliz@gnu.org>

427 script/batch file if we are under -n. Call _setmode to switch the
428 script file stream to text mode.

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

439 2006-02-15 Paul D. Smith <psmith@gnu.org>
441 Fix for Savannah bug #106.
443 * expand.c (expanding_var): Keep track of which variable we're
444 expanding. If no variable is being expanded, it's the same as
446 * make.h (expanding_var): Declare it.
447 * expand.c (recursively_expand_for_file): Set expanding_var to the
448 current variable we're expanding, unless there's no file info in
449 it (could happen if it comes from the command line or a default
450 variable). Restore it before we exit.

452 info instead of the reading_file info.

466 an impossible file, free it.
467 * variable.c (free_variable_set): New function.
468 * variable.h: Declare it.
470 * read.c (read_all_makefiles): Makefile names are kept in the
471 strcache, so there's never any need to alloc/free them.
474 * main.c (main): Add "archives" to the .FEATURES variable if
475 archive support is enabled.
476 * doc/make.texi (Special Variables): Document it.

490 A new internal capability: the string cache is a read-only cache
491 of strings, with a hash table interface for fast lookup. Nothing
492 in the cache will ever be freed, so there's no need for reference
493 counting, etc. This is the beginning of a full solution for
494 Savannah bug #15182, but for now we only store makefile names here.
496 * strcache.c: New file. Implement a read-only string cache.
497 * make.h: Add prototypes for new functions.
498 * main.c (initialize_global_hash_tables): Initialize the string cache.
499 (print_data_base): Print string cache stats.

505 * dir.c (dir_contents_file_exists_p): Don't opendir if the
506 directory time stamp didn't change, except on FAT filesystems.

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

543 * README.cvs: Updates for building from CVS.
545 2006-02-05 Paul D. Smith <psmith@gnu.org>
547 * file.c (enter_file): Keep track of the last double_colon entry,
548 to avoid walking the list every time we want to add a new one.
549 Fixes Savannah bug #15533.
550 * filedef.h (struct file): Add a new LAST pointer.
552 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do

578 2006-01-21 Eli Zaretskii <eliz@gnu.org>
580 * remake.c (update_goal_chain): Set g->changed instead of
581 incrementing it, as it is only 8-bit wide, and could overflow if
582 many commands got started in update_file.
584 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
586 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
587 MAXIMUM_WAIT_OBJECTS.

595 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
596 are already more children than sub_proc.c can handle, behave as if
597 the load were too high.
598 (start_job_command): Fix a typo in error message when process_easy
601 2006-01-14 Eli Zaretskii <eliz@gnu.org>
603 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
604 the shell is not sh.exe.
606 * job.c (create_batch_file): Renamed from create_batch_filename;
607 all callers changed. Don't close the temporary file; return its
608 file descriptor instead. New arg FD allows to return the file
610 (construct_command_argv_internal): Use _fdopen instead of fopen to
613 2006-01-04 Paul D. Smith <psmith@gnu.org>
615 * readme.vms: Updates for case-insensitive VMS file systems from
616 Hartmut Becker <Hartmut.Becker@hp.com>.

625 2006-01-03 Paul D. Smith <psmith@gnu.org>
627 * remake.c (update_file_1): Mark a prerequisite changed if it
630 * read.c (eval): Be sure to strip off trailing whitespace from the
631 prerequisites list properly. Also, initialize all fields in
632 struct dep when creating a new one.
634 2005-12-28 Paul D. Smith <psmith@gnu.org>
636 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
637 disable warnings for MSC.
638 Patch by Rob Tulloh <rtulloh@yahoo.com>.
640 2005-12-17 Eli Zaretskii <eliz@gnu.org>
642 * doc/make.texi (Execution): Add a footnote about changes in
643 handling of backslash-newline sequences. Mention the differences
644 on MS-DOS and MS-Windows.
646 * NEWS: More details about building the MinGW port and a pointer
647 to README.W32. Fix the section name that describes the new
648 backward-incompatible processing of backslash-newline sequences.
649 The special processing of SHELL set to "cmd" is only relevant to
650 MS-Windows, not MS-DOS.
652 2005-12-17 Eli Zaretskii <eliz@gnu.org>
654 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
655 to DWORD, to avoid compiler warnings.
656 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
657 use %ld in format, to avoid compiler warnings.

669 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
671 * read.c (record_target_var): Initialize variable's export field
672 with v_default instead of leaving it "initialized" by whatever
673 garbage happened to be on the heap.
675 2005-12-12 Paul D. Smith <psmith@gnu.org>
677 * make.1: Fix some display errors and document all existing options.
678 Patch provided by Mike Frysinger <vapier@gentoo.org>.
680 2005-12-11 Paul D. Smith <psmith@gnu.org>
682 * implicit.c (pattern_search): If 2nd expansion is not set for
683 this implicit rule, replace the pattern with the stem directly,
684 and don't re-expand the variable list. Along with the other
685 .SECONDEXPANSION changes below, fixes bug #13781.
687 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
689 * implicit.c (pattern_search): Mark other files that this rule
690 builds as targets so that they are not treated as intermediates
691 by the pattern rule search algorithm. Fixes bug #13022.
693 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
695 * remake.c (notice_finished_file): Propagate the change of
696 modification time to all the double-colon entries only if
697 it is the last one to be updated. Fixes bug #14334.
699 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
701 * function.c (func_flavor): Implement the flavor function which
702 returns the flavor of a variable.

704 * NEWS: Add it to the list of new functions.
706 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
708 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
710 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
711 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
713 2005-10-26 Paul Smith <psmith@gnu.org>
715 * read.c (record_files): Don't set deps flags if there are no deps.
716 * maintMakefile: We only need to build the templates when we are
717 creating a distribution, so don't do it for "all".
719 2005-10-24 Paul D. Smith <psmith@gnu.org>
721 Make secondary expansion optional: its enabled by declaring the
722 special target .SECONDEXPANSION.
724 * NEWS: Update information on second expansion capabilities.
725 * doc/make.texi (Secondary Expansion): Document the
726 .SECONDEXPANSION special target and its behavior.
727 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
728 prerequisite list was found in a static pattern rule.
729 (free_dep_chain): Declare a prototype.
730 * file.c (parse_prereqs): New function: break out some complexity
732 (expand_deps): If we aren't doing second expansion, replace % with
733 the stem for static pattern rules. Call the new function.
734 * filedef.h (parse_prereqs): Declare a prototype.
735 * implicit.c (pattern_search): Initialize the new staticpattern
737 * main.c (second_expansion): Declare a global variable to remember
738 if the special target has been seen. Initialize the new
739 staticpattern field for prerequisites.
740 * make.h: Extern for second_expansion.
741 * misc.c (free_dep_chain): New function: frees a struct dep list.
742 * read.c (read_all_makefiles): Initialize the staticpattern field.
743 (eval_makefile): Ditto.
744 (record_files): Check for the .SECONDEXPANSION target and set
745 second_expansion global if it's found.
746 Use the new free_dep_chain() instead of doing it by hand.
747 Set the staticpattern field for prereqs of static pattern targets.
749 2005-10-16 Paul D. Smith <psmith@gnu.org>
751 * main.c (main): Set CURDIR to be a file variable instead of a
752 default, so that values of CURDIR inherited from the environment
753 won't override the make value.
755 2005-09-26 Paul D. Smith <psmith@gnu.org>
757 * job.c (construct_command_argv_internal): If the line is empty
758 remember to free the temporary argv strings.
761 2005-09-16 Paul D. Smith <psmith@gnu.org>
763 * job.c (start_job_command): The noerror flag is a boolean (single
764 bit); set it appropriately.
765 Reported by Mark Eichin <eichin@metacarta.com>
767 2005-08-29 Paul D. Smith <psmith@gnu.org>
769 * function.c (func_error): On Windows, output from $(info ...)
770 seems to come in the wrong order. Try to force it with fflush().
772 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
774 * read.c (record_files): Move code that sets stem for static
775 pattern rules out of the if (!two_colon) condition so it is
776 also executed for two-colon rules. Fixes Savannah bug #13881.
778 2005-08-08 Paul D. Smith <psmith@gnu.org>
780 * make.h: Don't test that __STDC__ is non-0. Some compilers
781 (Windows for example) set it to 0 to denote "ISO C + extensions".
784 2005-08-07 Paul D. Smith <psmith@gnu.org>
786 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
787 conditional (slightly different version of a fix from Eli).
789 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
790 If make is running in parallel without -k and two jobs die in a
791 row, but not too close to each other, then make will quit without
792 waiting for the rest of the jobs to die.
794 * main.c (die): Don't reset err before calling reap_children() the
795 second time: we still want it to be in the error condition.
796 * job.c (reap_children): Use a static variable, rather than err,
797 to control whether or not the error message should be printed.
799 2005-08-06 Eli Zaretskii <eliz@gnu.org>
801 * w32/subproc/sub_proc.c: Include signal.h.
802 (process_pipe_io, process_file_io): Pass a pointer to a local
803 DWORD variable to GetExitCodeProcess. If the exit code is
804 CONTROL_C_EXIT, put SIGINT into pproc->signal.
806 * job.c [WINDOWS32]: Include windows.h.
807 (main_thread) [WINDOWS32]: New global variable.
808 (reap_children) [WINDOWS32]: Get the handle for the main thread
809 and store it in main_thread.
811 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
812 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
813 doing anything else. When we are done, close the main thread
814 handle and exit with status 130.
816 2005-07-30 Eli Zaretskii <eliz@gnu.org>
818 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
821 * main.c (find_and_set_default_shell): If found a DOSish shell,
822 set sh_found and the value of default_shell, and report the
823 findings in debug mode.
825 * job.c (construct_command_argv_internal): Check unixy_shell, not
826 no_default_sh_exe, to decide whether to use Unixy or DOSish
829 * README.W32: Update with info about the MinGW build.
831 * build_w32.bat: Support MinGW.
833 * w32/subproc/build.bat: Likewise.
835 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
838 * function.c (windows32_openpipe): Fix format strings for printing
841 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
843 (start_job_command): Fix format string for printing the result of
845 (start_job_command) [WINDOWS32]: Do not define.
846 (exec_command): Fix format string for printing HANDLE args.
848 * main.c (handle_runtime_exceptions): Fix sprintf format strings
849 to avoid compiler warnings.
850 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
851 (Note: some of these fixes were submitted independently by J. Grant)
853 2005-07-30 J. Grant <jg@jguk.org>
855 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
856 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
857 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
859 2005-07-15 Paul Smith <psmith@gnu.org>
861 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
862 we don't have a POSIX shell, then revert to the old
863 backslash-newline behavior (where they are stripped).
866 2005-07-08 Paul D. Smith <psmith@gnu.org>
868 * config.h.W32.template: Reorder to match the standard config.h,
869 for easier comparisons.
870 From J. Grant <jg@jguk.org>
872 * maintMakefile: Remove .dep_segment before overwriting it, in
873 case it's not writable or noclobber is set.
874 * expand.c (variable_expand_string): Cast result of pointer
875 arithmetic to avoid a warning.
876 * main.c (switches): Add full-fledged final initializer.
878 2005-07-06 Paul D. Smith <psmith@gnu.org>
880 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
881 * signame.c (strsignal): If we found _sys_siglist[] or
882 __sys_siglist[] use those instead of sys_siglist[].
883 From Albert Chin <china@thewrittenword.com>
885 2005-07-04 Paul D. Smith <psmith@gnu.org>
887 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
888 globfree(); set up to use the GNU versions.
889 From Martin Zinser <zinser@zinser.no-ip.info>
891 2005-07-03 Paul D. Smith <psmith@gnu.org>
893 From J. Grant <jg@jguk.org>:
895 * README.W32.template: Update the Windows and tested MSVC versions.
896 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
897 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
898 * build_w32.bat: Ditto.
899 * w32/subproc/build.bat: Ditto.
901 2005-06-28 Paul D. Smith <psmith@gnu.org>
903 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
904 declaration was checked but not present.
906 2005-06-27 Paul D. Smith <psmith@gnu.org>
908 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
909 to unsigned long. Fixes Savannah bug #13550.
911 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
912 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
913 Fixes Savannah bug #13551.
915 2005-06-26 Paul D. Smith <psmith@gnu.org>
917 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
918 it if ANSI_STRING is not set.
920 2005-06-25 Paul D. Smith <psmith@gnu.org>
922 * read.c (eval): If no filenames are passed to any of the
923 "include" variants, don't print an error.
924 * doc/make.texi (Include): Document this.
925 Fixes Savannah bug #1761.
927 * job.c (construct_command_argv_internal): Sanitize handling of
928 backslash/newline pairs according to POSIX: that is, keep the
929 backslash-newline in the command script, but remove a following
930 TAB character, if present. In the fast path, make sure that the
931 behavior matches what the shell would do both inside and outside
932 of quotes. In the slow path, quote the backslash and put a
933 literal newline in the string.
934 Fixes Savannah bug #1332.
935 * doc/make.texi (Execution): Document the new behavior and give
937 * NEWS: Make a note of the new behavior.
939 * make.h [WINDOWS32]: #include <direct.h>.
940 Fixes Savannah bug #13478.
942 * remake.c (name_mtime): If the stat() of a file fails and the -L
943 option was given and the file is a symlink, take the best mtime of
944 the symlink we can get as the mtime of the file and don't fail.
945 Fixes Savannah bug #13280.
947 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
948 If it's set, then don't stop on STOPCHARs or BLANKs if they're
949 inside a variable reference. Make this function static as it's
951 (eval): Call find_char_unquote() with IGNOREVARS set when we're
952 parsing an unexpanded line looking for semicolons.
953 Fixes Savannah bug #1454.
954 * misc.c (remove_comments): Move this to read.c and make it static
955 as it's only used there. Call find_char_unquote() with new arg.
956 * make.h: Remove prototypes for find_char_unquote() and
957 remove_comments() since they're static now.
959 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
960 its export flag and obtain its value. When we need to re-exec,
961 increment the value and add it into the environment.
962 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
963 * NEWS: Mention MAKE_RESTARTS.
964 * main.c (always_make_set): New variable. Change the -B option to
965 set this one instead.
966 (main): When checking makefiles, only set always_make_flag if
967 always_make_set is set AND the restarts flag is 0. When building
968 normal targets, set it IFF always_make_set is set.
969 (main): Avoid infinite recursion with -W, too: only set what-if
970 files to NEW before we check makefiles if we've never restarted
971 before. If we have restarted, set what-if files to NEW _after_ we
973 Fixes Savannah bug #7566:
975 2005-06-17 Paul D. Smith <psmith@gnu.org>
977 * default.c: Change VMS implicit rules to use $$$$ instead of $$
978 in the prerequisites list.
980 2005-06-12 Paul D. Smith <psmith@gnu.org>
982 Fix Savannah bug # 1328.
984 * configure.in: Check for atexit().
985 * misc.c (close_stdout): Test stdout to see if writes to it have
986 failed. If so, be sure to exit with a non-0 error code. Based on
987 code found in gnulib.
989 * main.c (main): Install close_stdout() with atexit().
991 2005-06-10 Paul D. Smith <psmith@gnu.org>
993 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
995 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
996 headers; make vmsWaitForChildren() static; extern vmsify().
997 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
998 Don't create child_execute_job() here (it's in vmsjobs.c).
999 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1001 2005-06-09 Paul D. Smith <psmith@gnu.org>
1003 * variable.c (push_new_variable_scope): File variables point
1004 directly to the global_setlist variable. So, inserting a new
1005 scope in front of that has no effect on those variables: they
1006 don't go through current_variable_set_list. If we're pushing a
1007 scope and the current scope is global, push it "the other way" so
1008 that the new setlist is in the global_setlist variable, and
1009 next points to a new setlist with the global variable set.
1010 (pop_variable_scope): Properly undo a push with the new
1012 Fixes Savannah bug #11913.
1014 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1016 * job.c (reap_children): Don't die of the command failed but
1017 the dontcare flag is set. Fixes Savannah bug #13216.
1019 * implicit.c (pattern_search): When creating a target from
1020 an implicit rule match, lookup pattern target and set precious
1021 flag in a newly created target. Fixes Savannah bug #13218.
1023 2005-05-13 Paul D. Smith <psmith@gnu.org>
1025 Implement "if... else if... endif" syntax.
1027 * read.c (eval): Push all checks for conditional words ("ifeq",
1028 "else", etc.) down into the conditional_line() function.
1029 (conditional_line): Rework to allow "else if..." clause. New
1030 return value -2 for lines which are not conditionals. The
1031 ignoring flag can now also be 2, which means "already parsed a
1032 true branch". If that value is seen no other branch of this
1033 conditional can be considered true. In the else parsing if there
1034 is extra text after the else, invoke conditional_line()
1035 recursively to see if it's another conditional. If not, it's an
1036 error. If so, raise the conditional value to this level instead
1037 of creating a new conditional nesting level. Special check for
1038 "else" and "endif", which aren't allowed on the "else" line.
1039 * doc/make.texi (Conditional Syntax): Document the new syntax.
1041 2005-05-09 Paul D. Smith <psmith@gnu.org>
1043 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1044 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1045 recurses to the w32 directory, even on non-Windows systems. Use
1046 the method suggested in the automake manual.
1047 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1048 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1050 2005-05-07 Paul D. Smith <psmith@gnu.org>
1052 * main.c (die): If we're dying with a fatal error (not that a
1053 command has failed), write back any leftover tokens before we go.
1055 * job.c (set_child_handler_action_flags): If there are jobs
1056 waiting for the load to go down, set an alarm to go off in 1
1057 second. This allows us to wake up from a potentially long-lasting
1058 read() and start a new job if the load has gone down. Turn it off
1060 (job_noop): Dummy signal handler function.
1061 (new_job): Invoke it with the new semantics.
1063 * docs/make.texi: Document secondary expansion. Various cleanups
1066 2005-05-03 Paul D. Smith <psmith@gnu.org>
1068 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1069 the targets which are to ultimately be made are called "goals";
1070 see the GNU make manual. Also, MAKECMDGOALS, etc.
1072 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1073 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1074 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1076 2005-05-02 Paul D. Smith <psmith@gnu.org>
1078 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1079 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1080 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1081 functions to vmsjobs.c. #include it into jobs.c.
1083 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1084 jobserver tokens. I found that this happens when an exported
1085 recursive variable contains a $(shell ...) function reference: in
1086 this situation we could "forget" to write back a token.
1088 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1089 we have. It's not reliable to depend on the number of children in
1090 our linked list so keep a separate count.
1091 (new_job): Check jobserver_tokens rather than children &&
1092 waiting_jobs. Increment jobserver_tokens when we get one.
1093 (free_child): If jobserver_tokens is 0, internal error. If it's
1094 >1, write a token back to the jobserver pipe (we don't write a
1095 token for the "free" job). Decrement jobserver_tokens.
1097 * main.c: Add variable master_job_slots.
1098 (main): Set it to hold the number of jobs requested if we're the
1099 master process, when using the jobserver.
1100 (die): Sanity checks: first test jobserver_tokens to make sure
1101 this process isn't holding any tokens we didn't write back.
1102 Second, if master_job_slots is set count the tokens left in the
1103 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1105 2005-04-24 Paul D. Smith <psmith@gnu.org>
1107 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1108 with -l# can lose jobserver tokens, because waiting jobs are not
1109 consulted properly when checking for the "free" token.
1111 * job.c (free_child): Count waiting_jobs as having tokens.
1112 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1113 handle jobs waiting for the load to drop.
1115 2005-04-23 Paul D. Smith <psmith@gnu.org>
1117 * main.c (main): Be careful to not core if a variable setting in
1118 the environment doesn't contain an '='. This is illegal but can
1119 happen in broken setups.
1120 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1122 2005-04-12 Paul D. Smith <psmith@gnu.org>
1124 The second expansion feature causes significant slowdown. Timing
1125 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1126 read the makefile before the feature, to 11+s to do the same
1127 operations after the feature. Additionally, memory usage
1128 increased drastically. To fix this I added some intelligence that
1129 avoids the overhead of the second expansion unless it's required.
1131 * dep.h: Add a new boolean field, need_2nd_expansion.
1133 * read.c (eval): When creating the struct dep for the target,
1134 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1135 (record_files): If there's a "%" in a static pattern rule, it gets
1136 converted to "$*" so set need_2nd_expansion to 1.
1138 * file.c (expand_deps): Rework to be more efficient. Only perform
1139 initialize_file_variables(), set_file_variables(), and
1140 variable_expand_for_file() if the need_2nd_expansion is set.
1142 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1143 (pattern_search): Ditto.
1144 * main.c (handle_non_switch_argument): Ditto.
1146 * read.c (read_all_makefiles): Ditto.
1147 (eval_makefile): Ditto.
1149 2005-04-07 Paul D. Smith <psmith@gnu.org>
1151 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1152 * variable.c (sync_Path_environment): Ditto.
1153 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1155 * main.c (main): Define the .FEATURES variable.
1156 * NEWS: Announce .FEATURES.
1157 * doc/make.texi (Special Variables): Document .FEATURES.
1159 * remake.c (check_dep): If a file is .PHONY, update it even if
1160 it's marked intermediate. Fixes Savannah bug #12331.
1162 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1164 * file.c (expand_deps): Factor out the second expansion and
1165 prerequisite line parsing logic from snap_deps().
1167 * file.c (snap_deps): Use expand_deps(). Expand and parse
1168 prerequisites of the .SUFFIXES special target first. Fixes
1169 Savannah bug #12320.
1171 2005-03-13 Paul D. Smith <psmith@gnu.org>
1173 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1176 2005-03-11 Paul D. Smith <psmith@gnu.org>
1178 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1179 available, not undefined (from Earnie Boyd).
1181 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1183 * implicit.c (pattern_search): Mark an intermediate target as
1184 precious if it happened to be a prerequisite of some (other)
1185 target. Fixes Savannah bug #12267.
1187 2005-03-09 Paul D. Smith <psmith@gnu.org>
1189 * read.c (eval_makefile): Add alloca(0).
1190 (eval_buffer): Ditto.
1192 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1194 * main.c (main): Use o_file instead of o_default when defining
1195 the .DEFAULT_TARGET special variable.
1196 * read.c (eval): Use define_variable_global() instead of
1197 define_variable() when setting new value for the .DEFAULT_TARGET
1198 special variable. Fixes Savannah bug #12266.
1200 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1202 * imlicit.c (pattern_search): Mark files for which an implicit
1203 rule has been found as targets. Fixes Savannah bug #12202.
1205 2005-03-04 Paul D. Smith <psmith@gnu.org>
1208 * doc/make.texi (Automatic Variables): Document $|.
1210 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1212 * read.c (record_files): Instead of substituting % with
1213 actual stem value in dependency list replace it with $*.
1214 This fixes stem triple expansion bug.
1216 * implicit.c (pattern_search): Copy stem to a separate
1217 buffer and make it a properly terminated string. Assign
1218 this buffer instead of STEM (which is not terminated) to
1219 f->stem. Instead of substituting % with actual stem value
1220 in dependency list replace it with $*. This fixes stem
1221 triple expansion bug.
1223 2005-03-01 Paul D. Smith <psmith@gnu.org>
1225 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1226 on Windows, as it takes a handle not a pid. Just exit.
1227 Fix from patch #3679, provided by Alessandro Vesely.
1229 * configure.in: Update check for sys_siglist[] from autoconf manual.
1230 * signame.c (strsignal): Update to use the new autoconf macro.
1232 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1234 * read.c (record_files): Add a check for the list of prerequisites
1235 of a static pattern rule being empty. Fixes Savannah bug #12180.
1237 2005-02-28 Paul D. Smith <psmith@gnu.org>
1239 * doc/make.texi (Text Functions): Update docs to allow the end
1240 ordinal for $(wordlist ...) to be 0.
1241 * function.c (func_wordlist): Fail if the start ordinal for
1242 $(wordlist ...) is <1. Matches documentation.
1243 Resolves Savannah support request #103195.
1245 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1246 previously we were stopping when !-q, exactly the opposite. This
1247 has been wrong since version 1.34, in 1994!
1248 (update_file): If we got an error don't break out to run more
1249 double-colon rules: just return immediately.
1250 Fixes Savannah bug #7144.
1252 2005-02-27 Paul D. Smith <psmith@gnu.org>
1254 * misc.c (end_of_token): Make argument const.
1255 * make.h: Update prototype.
1257 * function.c (abspath, func_realpath, func_abspath): Use
1258 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1259 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1260 * read.c (record_files): Ditto.
1261 * variable.c (do_variable_definition): Ditto.
1263 * function.c (func_error): Create a new function $(info ...) that
1264 simply prints the message to stdout with no extras.
1265 (function_table_init): Add new function to the table.
1266 * NEWS: Add $(info ...) reference.
1267 * doc/make.texi (Make Control Functions): Document it.
1269 New feature: if the system supports symbolic links, and the user
1270 provides the -L/--check-symlink-time flag, then use the latest
1271 mtime between the symlink(s) and the target file.
1273 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1274 readlink(). If both are available, define MAKE_SYMLINKS.
1275 * main.c: New variable: check_symlink_flag.
1276 (usage): Add a line for -L/--check-symlink-times to the help string.
1277 (switches): Add -L/--check-symlink-times command line argument.
1278 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1279 print a warning and disable it again.
1280 * make.h: Declare check_symlink_flag.
1281 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1282 if the file is a symlink then check each link in the chain and
1283 choose the NEWEST mtime we find as the mtime for the file. The
1284 newest mtime might be the file itself!
1285 * NEWS: Add information about this new feature.
1286 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1288 Avoid core dumps described in Savannah bug # 12124:
1290 * file.c: New variable snapped_deps remember whether we've run
1292 (snap_deps): Set it.
1293 * filedef.h: Extern it.
1294 * read.c (record_files): Check snapped_deps; if it's set then
1295 we're trying to eval a new target/prerequisite relationship from
1296 within a command script, which we don't support. Fatal.
1298 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1300 Implementation of the .DEFAULT_TARGET special variable.
1302 * read.c (eval): If necessary, update default_target_name when
1304 * read.c (record_files): Update default_target_file if
1305 default_target_name has changed.
1306 * main.c (default_target_name): Define.
1307 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1308 default_target_name is set use default_target_file as a root
1310 * filedef.h (default_target_name): Declare.
1311 * dep.h (free_dep_chain):
1312 * misc.c (free_dep_chain): Change to operate on struct nameseq
1313 and change name to free_ns_chain.
1314 * file.c (snap_deps): Update to use free_ns_chain.
1316 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1318 Implementation of the second expansion in explicit rules,
1319 static pattern rules and implicit rules.
1321 * read.c (eval): Refrain from chopping up rule's dependencies.
1322 Store them in a struct dep as a single dependency line. Remove
1323 the code that implements SySV-style automatic variables.
1325 * read.c (record_files): Adjust the code that handles static
1326 pattern rules to expand all percents instead of only the first
1327 one. Reverse the order in which dependencies are stored so that
1328 when the second expansion reverses them again they appear in
1329 the makefile order (with some exceptions, see comments in
1330 the code). Remove the code that implements SySV-style automatic
1333 * file.c (snap_deps): Implement the second expansion and chopping
1334 of dependency lines for explicit rules.
1336 * implicit.c (struct idep): Define an auxiliary data type to hold
1337 implicit rule's dependencies after stem substitution and
1340 * implicit.c (free_idep_chain): Implement.
1342 * implicit.c (get_next_word): Implement helper function for
1343 parsing implicit rule's dependency lines into words taking
1344 into account variable expansion requests. Used in the stem
1347 * implicit.c (pattern_search): Implement the second expansion
1348 for implicit rules. Also fixes bug #12091.
1350 * commands.h (set_file_variables): Declare.
1351 * commands.c (set_file_variables): Remove static specifier.
1353 * dep.h (free_dep_chain): Declare.
1354 * misc.c (free_dep_chain): Implement.
1356 * variable.h (variable_expand_for_file): Declare.
1357 * expand.c (variable_expand_for_file): Remove static specifier.
1359 * make.h (strip_whitespace): Declare.
1360 * function.c (strip_whitespace): Remove static specifier.
1362 2005-02-26 Paul D. Smith <psmith@gnu.org>
1364 * main.c (main): Check for ferror() when reading makefiles from stdin.
1365 Apparently some shells in Windows don't close pipes properly and
1368 2005-02-24 Jonathan Grant <jg@jguk.org>
1370 * configure.in: Add MinGW configuration options, and extra w32 code
1372 * Makefile.am: Add MinGW configuration options, and extra w32 code
1374 * main.c: Determine correct program string (after last \ without .exe).
1375 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1377 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1378 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1379 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1380 environment support.
1382 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1384 * function.c (func_shell): When initializing error_prefix, check
1385 that reading file name is not null. This fixes long-standing
1386 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1388 2005-02-09 Paul D. Smith <psmith@gnu.org>
1390 * maintMakefile: Update the CVS download URL to simplify them.
1391 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1392 downloading the .texi files from Savannah now.
1394 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1396 * main.c (handle_non_switch_argument): Only add variables to
1397 command_variables if they're not already there: duplicate settings
1398 waste space and can be confusing to read.
1400 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1401 this header is never included by non-WINDOWS32 code, and it
1402 requires <config.h> to define which isn't always included first.
1404 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1405 testing MINGW32 versions.
1407 * main.c (log_working_directory): flush stdout to be sure the WD
1408 change is printed before any stderr messages show up.
1410 2005-02-01 Paul D. Smith <psmith@gnu.org>
1412 * maintMakefile (po_repo): Update the GNU translation site URL.
1414 2004-12-01 Paul D. Smith <psmith@gnu.org>
1416 * main.c (main): Change char* env_shell to struct variable shell_var.
1417 * variable.c (target_environment): Use new shell_var.
1419 2004-11-30 Paul D. Smith <psmith@gnu.org>
1421 * configure.in: The old way we avoided creating build.sh from
1422 build.sh.in before build.sh.in exists doesn't work anymore; we
1423 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1424 the help!). This also keeps automake from complaining.
1425 * Makefile.am (README): Add a dummy target so automake won't
1426 complain that this file doesn't exist when we checkout from CVS.
1427 * maintMakefile (.dep_segment): Rewrite this rule since newer
1428 versions of automake don't provide DEP_FILES.
1430 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1432 Implementation of `realpath' and `abspath' built-in functions.
1434 * configure.in: Check for realpath.
1435 * function.c (abspath): Return an absolute file name that does
1436 not contain any `.' or `..' components, nor repeated `/'.
1437 * function.c (func_abspath): For each name call abspath.
1438 * function.c (func_realpath): For each name call realpath
1439 from libc or delegate to abspath if realpath is not available.
1440 * doc/make.texi (Functions for File Names): Document new functions.
1441 * doc/make.texi (Quick Reference): Ditto.
1443 2004-11-28 Paul D. Smith <psmith@gnu.org>
1445 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1446 arguments. Fixes bug #10252.
1448 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1450 * main.c (main): Set SHELL to v_noexport by default. Remember the
1451 original environment setting of SHELL in the env_shell variable.
1452 * main.h: Export new env_shell variable.
1453 * variable.c (target_environment): If we find a v_noexport
1454 variable for SHELL, add a SHELL variable with the env_shell value.
1455 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1456 * doc/make.texi (Variables/Recursion): Ditto.
1458 2004-11-28 Paul D. Smith <psmith@gnu.org>
1460 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1461 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1462 Patch by Alessandro Vesely.
1464 2004-11-12 Paul D. Smith <psmith@gnu.org>
1466 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1467 the command line if it's inside a string.
1468 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1470 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1472 * function.c (func_lastword): New function: return last word
1473 from the list of words.
1474 * doc/make.texi: Document $(lastword ). Fix broken links in
1475 Quick Reference section.
1477 2004-10-06 Paul D. Smith <psmith@gnu.org>
1479 Apply patch from Alessandro Vesely, provided with bug # 9748.
1480 Fix use of tmpnam() to work with Borland C.
1482 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1483 construction of a temporary filename, and call new function
1484 create_batch_filename().
1485 (create_batch_filename) [WINDOWS32]: New function to create a
1488 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1490 * read.c (record_target_var): Expand simple pattern-specific
1492 * variable.c (initialize_file_variables): Do not expand simple
1493 pattern-specific variable.
1495 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1497 * remake.c (update_file_1): When rebuilding makefiles inherit
1498 dontcare flag from a target that triggered update.
1500 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1502 * variable.c (initialize_file_variables): Mark pattern-specific
1503 variable as a per-target and copy export status.
1505 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1507 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1509 * implicit.c (pattern_search): When considering an implicit rule's
1510 prerequisite check that it is actually a target rather then
1511 just an entry in the file hashtable.
1513 2004-09-21 Paul D. Smith <psmith@gnu.org>
1515 * read.c (readstring): Fix some logic errors in backslash handling.
1516 (eval): Remove some unnecessary processing in buffer handling.
1517 (record_target_var): Assert that parse_variable_definition() succeeded.
1518 Reported by: Markus Mauhart <qwe123@chello.at>.
1520 * misc.c: Removed the sindex() function. All instances of this
1521 function were trivially replaceable by the standard strstr()
1522 function, and that function will always have better (or certainly
1523 no worse) performance than the very simple-minded algorithm
1524 sindex() used. This can matter with complex makefiles.
1525 * make.h: Remove the prototype for sindex().
1526 * function.c (subst_expand): Convert sindex() call to strstr().
1527 This means we no longer need to track the TLEN value so remove that.
1528 (func_findstring): Convert sindex() to strstr().
1529 * commands.c (chop_commands): Convert sindex() calls to strstr().
1530 Suggested by: Markus Mauhart <qwe123@chello.at>.
1532 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1533 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1534 If SHELL is set to CMD.EXE then assume it's batch-mode and
1535 non-unixy. I wrote the code differently from the patch, though,
1536 to make it safer. This also resolves bug #9174.
1538 2004-09-20 Paul D. Smith <psmith@gnu.org>
1540 * expand.c (variable_expand_string): Modify to invoke
1541 patsubst_expand() instead of subst_expand(); the latter didn't
1542 handle suffix patterns correctly.
1543 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1544 was used only from variable_expand_string() and is no longer used
1546 (func_subst): Ditto, on call to subst_expand().
1547 (patsubst_expand): Require the percent pointers to point to the
1548 character after the %, not to the % itself.
1549 * read.c (record_files): New call criteria for patsubst_expand().
1550 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1551 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1553 2004-09-19 Paul D. Smith <psmith@gnu.org>
1555 * function.c (subst_expand): Fix a check in by_word: look for a
1556 previous blank if we're beyond the beginning of the string, not
1557 the beginning of the word.
1558 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1560 2004-05-16 Paul D. Smith <psmith@gnu.org>
1562 * remake.c (update_goal_chain): Change the argument specifying
1563 whether we're rebuilding makefiles to be a global variable,
1564 REBUILDING_MAKEFILES.
1565 (complain): Extract the code that complains about no rules to make
1566 a target into a separate function.
1567 (update_file_1): If we tried to rebuild a file during the makefile
1568 rebuild phase and it was dontcare, then no message was printed.
1569 If we then try to build the same file during the normal build,
1570 print a message this time.
1571 (remake_file): Don't complain about un-remake-able files when
1572 we're rebuilding makefiles.
1574 2004-05-11 Paul D. Smith <psmith@gnu.org>
1576 * job.c (construct_command_argv_internal): OS/2 patches from
1577 Andreas Buening <andreas.buening@nexgo.de>.
1579 2004-05-10 Paul D. Smith <psmith@gnu.org>
1581 * remake.c (update_file): Don't walk the double-colon chain unless
1582 this is a double-colon rule. Fix suggested by Boris Kolpackov
1583 <boris@kolpackov.net>.
1585 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1586 * readme.vms: New section describing OpenVMS support and issues.
1587 * default.c (default_variables): Add support for IA64.
1588 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1589 without some privilege aborts make with the error
1590 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1591 pressing Ctrl+Y and the input device is no terminal. The change
1592 catches this error and just continues.
1594 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1596 2004-04-25 Paul D. Smith <psmith@gnu.org>
1598 * commands.c (set_file_variables): Set $< properly in the face of
1599 order-only prerequisites.
1600 Patch from Boris Kolpackov <boris@kolpackov.net>
1602 2004-04-21 Bob Byrnes <byrnes@curl.com>
1604 * main.c (main): Notice failures to remake makefiles.
1606 2004-03-28 Paul D. Smith <psmith@gnu.org>
1608 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1610 * job.c: No default shell for RISC OS.
1611 (load_too_high): Hard-code the return to 1.
1612 (construct_command_argv_internal): No sh_chars or sh_cmds.
1613 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1615 2004-03-20 Paul D. Smith <psmith@gnu.org>
1617 * variable.c (do_variable_definition): Don't append from the
1618 global set if a previous non-appending target-specific variable
1619 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1622 * expand.c (reference_variable): Don't give up on variables with
1623 no value that have the target-specific append flag set: they might
1624 have a value after all. Reported by Oliver Schmidt
1625 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1626 <nikulin@dx1cmd.inp.nsk.su>.
1628 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1629 refer to absolute pathnames in directories that don't exist: some
1630 portion of the makefile could create those directories before we
1631 match the pattern. Fixes bugs #775 and #108.
1633 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1635 * main.c (main): Free makefile_mtimes if we have any.
1636 * README.W32.template: Update documentation for the current status
1637 of the MS-Windows port.
1638 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1639 environment variable is sometimes already defined which causes the
1641 * main.c (debug_signal_handler): Only define this function if
1642 SIGUSR1 is available.
1644 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1646 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1647 * README.OS2.template: Documentation updates.
1648 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1649 link line for safety.
1650 * maintMakefile (build.sh.in): Remove an extraneous ")".
1651 * job.c (child_execute_job): Close saved FDs.
1652 * job.c (exec_command) [OS/2]: exec_command(): If the command
1653 can't be exec'ed and if the shell is not Unix-sh, then try again
1654 with argv = { "cmd", "/c", ... }. Normally, this code is never
1655 reached for the cmd shell unless the command really doesn't exist.
1656 (construct_command_argv_internal) [OS/2]: The code for cmd
1657 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1658 The CMD builtin commands are case insensitive so use strcasecmp().
1660 2004-03-19 Paul D. Smith <psmith@gnu.org>
1662 * read.c (do_define): Re-order line counter increment so the count
1663 is accurate (we were losing one line per define). Reported by
1664 Dave Yost <Dave@Yost.com>.
1666 2004-03-06 Paul D. Smith <psmith@gnu.org>
1668 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1670 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1671 * misc.c (message,error,fatal): Ditto.
1672 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1673 * config.h.W32.template: Ditto.
1674 * config.h-vms.template: Ditto.
1675 * config.ami.template: Ditto.
1677 2004-03-04 Paul D. Smith <psmith@gnu.org>
1679 * README.template: Add a note about broken /bin/sh on SunOS
1680 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1682 * misc.c (message, error, fatal): Don't use "..." if we're using
1683 varargs. ansi2knr should handle this but it doesn't work: it
1684 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1685 done. On many systems (SunOS for example) va_dcl is a #define.
1686 So, force the use of the non-"..." version on pre-ANSI compilers.
1688 * maintMakefile (sign-dist): Create some rules to help automate
1689 the new GNU ftp upload method.
1691 2004-02-24 Paul D. Smith <psmith@gnu.org>
1693 * config.h.W32.template: Add HAVE_STDARG_H
1694 * config.h-vms.template: Ditto.
1695 * config.ami.template: Ditto.
1697 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1699 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1700 * build_w32.bat: Remove extra "+".
1702 2004-02-23 Paul D. Smith <psmith@gnu.org>
1704 * make.h: Create an UNUSED macro to mark unused parameters.
1705 * (many): Clean up warnings by applying UNUSED, fixing
1706 signed/unsigned incompatibilities, etc.
1708 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1710 * filedef.h: Name the command_state enumeration.
1711 * file.c (set_command_state): Use the enumeration in the function
1714 * configure.in: Explicitly set SET_MAKE to empty, to disable
1715 MAKE=make even when no make already exists. Fix bug #3823.
1717 2004-02-22 Paul D. Smith <psmith@gnu.org>
1719 * maintMakefile: Perl script to clean up all non-CVS files. Use
1720 it on all the subdirectories for the cvs-clean target.
1722 * main.c (decode_switches): Require non-empty strings for all our
1723 string command-line options. Fixes Debian bug # 164165.
1725 * configure.in: Check for stdarg.h and varargs.h.
1726 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1727 for printing messages.
1728 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1733 A number of patches for OS/2 support from Andreas Buening
1734 <andreas.buening@nexgo.de>:
1736 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1737 disable the SIGCHLD handler.
1738 (reap_children) [OS/2]: Remove special handling of job_rfd.
1739 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1740 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1741 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1742 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1743 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1746 2004-02-21 Paul D. Smith <psmith@gnu.org>
1748 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1749 <mail@kristov.de> reports that if process_begin() fails we don't
1750 handle the error condition correctly in all cases.
1751 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1752 to have a newline on the message.
1754 * job.c (construct_command_argv_internal): Add "test" to UNIX
1755 sh_cmds[]. Fixes Savannah bug # 7606.
1757 2004-02-04 Paul D. Smith <psmith@gnu.org>
1759 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1760 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1761 Hartmut Becker <Hartmut.Becker@hp.com>.
1763 2004-01-21 Paul D. Smith <psmith@gnu.org>
1765 * job.c (load_too_high): Implement an algorithm to control the
1766 "thundering herd" problem when using -l to control job creation
1767 via the load average. The system only recomputes the load once a
1768 second but we can start many jobs in a second. To solve this we
1769 keep track of the number of jobs started in the last second and
1770 apply a weight to try to guess what a correct load would be.
1771 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1772 Also fixes bug #4693.
1773 (reap_children): Decrease the job count for this second.
1774 (start_job_command): Increase the job count for this second.
1776 * read.c (conditional_line): Expand the text after ifn?def before
1777 checking to see if it's a single word. Fixes bug #7257.
1779 2004-01-09 Paul D. Smith <psmith@gnu.org>
1781 * file.c (print_file): Recurse to print all targets in
1782 double-colon rules. Fixes bug #4518, reported (with patch) by
1783 Andrew Chatham <chatham@google.com>.
1785 2004-01-07 Paul D. Smith <psmith@gnu.org>
1787 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1788 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1789 AC_FUNC_SETVBUF_REVERSED.
1791 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1792 (MAKE Variable): Fix Savannah bug #4898.
1794 * job.c (construct_command_argv_internal): Add "!" to the list of
1795 shell escape chars. POSIX sh allows it to appear before a
1796 command, to negate the exit code. Fixes bug #6404.
1798 * implicit.c (pattern_search): When matching an implicit rule,
1799 remember which dependencies have the ignore_mtime flag set.
1800 Original fix provided in Savannah patch #2349, by Benoit
1801 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1803 2003-11-22 Paul D. Smith <psmith@gnu.org>
1805 * README.W32.template (Outputs): Clarification on -j with
1806 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1809 2003-11-02 Paul D. Smith <psmith@gnu.org>
1811 * function.c (func_if): Strip all the trailing whitespace from the
1812 condition, then don't expand it. Fixed bug # 5798.
1814 * expand.c (recursively_expand_for_file): If we're expanding a
1815 variable with no file context, then use the variable's context.
1818 2003-10-21 Paul D. Smith <psmith@gnu.org>
1820 * main.c (log_working_directory): Add newlines to printf()s.
1822 * README.cvs: Add a note to ignore warnings during autoreconf.
1824 * maintMakefile (po_repo): Set a new URL for PO file updates.
1825 (get-config/config.guess get-config/config.sub): Get these files
1826 from the Savannah config project instead of ftp.gnu.org.
1828 2003-10-05 Paul Eggert <eggert@twinsun.com>
1830 * main.c (main): Avoid potential subscript error if environ has
1833 2003-08-22 Paul D. Smith <psmith@gnu.org>
1835 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1836 systems which don't yet implement the C89 standard :-/.
1838 2003-07-18 Paul D. Smith <psmith@gnu.org>
1840 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1841 [WINDOWS32]: Initialize hash.
1843 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1845 * dir.c (read_dirstream): Provide a workaround for broken versions of
1846 the MinGW dirent structure.
1848 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1850 * w32/include/dirent.h: Add __MINGW32__ filter.
1852 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1854 * make.h: Add global declaration of *make_host.
1855 * main.c (print_usage): Remove local declaration of *make_host.
1856 (print_version): Display "This program built for ..." after Copyright
1859 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1861 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1862 execution of "makeinfo --html make.texi".
1864 2003-04-30 Paul D. Smith <psmith@gnu.org>
1866 * build.template: Make some changes to maybe allow this script to
1867 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1869 * README.OS2.template: New file for OS/2 support. Original
1870 contributed by Andreas Buening.
1871 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1874 2003-04-19 Paul D. Smith <psmith@gnu.org>
1876 Fix bug #1405: allow a target to match multiple pattern-specific
1879 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1880 variable.c, where they've always belonged.
1881 * rule.h: Move the prototypes and struct pattern_var as well.
1882 * variable.c (initialize_file_variables): Invoke
1883 lookup_pattern_var() in a loop, until no more matches are found.
1884 If a match is found, create a new variable set for the target's
1885 pattern variables. Then merge the contents of each matching
1886 pattern variable set into the target's pattern variable set.
1887 (lookup_pattern_var): Change this function to be usable
1888 in a loop. It takes a starting position: if NULL, start at the
1889 beginning; if non-NULL, start with the pattern variable after that
1890 position, and return the next matching pattern.
1891 (create_pattern_var): Create a unique instance of
1892 pattern-specific variables for every definition in the makefile.
1893 Don't combine the same pattern together. This allows us to
1894 process the variable handling properly even when the same pattern
1895 is used multiple times.
1896 (parse_variable_definition): New function: break out the parsing
1897 of a variable definition line from try_variable_definition.
1898 (try_variable_definition): Call parse_variable_definition to
1900 (print_variable_data_base): Print out pattern-specific variables.
1901 * variable.h (struct variable): Remember when a variable is
1902 conditional. Also remember its flavor.
1903 (struct pattern_var): Instead of keeping a variable set, we just
1904 keep a single variable for each pattern.
1905 * read.c (record_target_var): Each pattern variable contains only a
1906 single variable, not a set, so create it properly.
1907 * doc/make.texi (Pattern-specific): Document the new behavior.
1909 2003-04-17 Paul D. Smith <psmith@gnu.org>
1911 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1912 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1913 file/directory naming rules for VMS so I can't tell whether this
1916 2003-04-09 Paul D. Smith <psmith@gnu.org>
1918 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1919 DOS-style pathnames: backslash separators and drive specifiers.
1921 2003-03-28 Paul D. Smith <psmith@gnu.org>
1923 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1924 the intermediate flag on all targets. Fixes bug #2515.
1926 2003-03-24 Paul D. Smith <psmith@gnu.org>
1928 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1929 Upgrade to autoconf 2.57 and automake 1.7.3.
1931 * job.c: More OS/2 changes from Andreas Buening.
1933 * file.c (print_file): Fix variable initialization.
1936 * remake.c (notice_finished_file):
1938 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1939 some calls (like readdir()) return NULL in valid situations
1940 without resetting errno. Fixes bug #2846.
1942 2003-02-25 Paul D. Smith <psmith@gnu.org>
1944 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1946 * job.c (_is_unixy_shell) [OS/2]: New function.
1947 Set default shell to /bin/sh.
1948 (reap_children): Close the job_rfd pipe here since we don't use a
1950 (set_child_handler_action_flags): define this to empty on OS/2.
1951 (start_job_command): Close the jobserver pipe and use
1952 child_execute_job() instead of fork/exec.
1953 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1954 rather than exec'ing, then reconfigure stdin/stdout.
1955 (exec_command): Rewrite to use spawn instead of exec. Return the
1958 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1959 in DOS. Handle the TEMP environment variable as in DOS. Don't
1960 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1961 use -j in DOS mode. Use child_execute_job() instead of
1964 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1967 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1968 prototypes that return values.
1970 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1972 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1973 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1975 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1978 2003-02-24 Paul D. Smith <psmith@gnu.org>
1980 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1981 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1982 (child_execute_job) [VMS]: Handle error status properly.
1983 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1985 * function.c (func_shell): Use EINTRLOOP() while reading from the
1986 subshell pipe (Fixes bug #2502).
1987 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1989 * main.c (main): Ditto.
1991 2003-01-30 Paul D. Smith <psmith@gnu.org>
1993 * read.c (eval): eval() was not fully reentrant, because the
1994 collapsed buffer was static. Change it to be an automatic
1995 variable so that eval() can be invoked recursively.
1997 (eval): Apply patch # 1022: fix memory reference error on long
1998 target-specific variable lines.
1999 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2001 * function.c (check_numeric): Combine the is_numeric() function
2002 into this function, since it's only called from one place.
2003 Constify this function. Have it print the incorrect string in the
2004 error message. Fixes bug #2407.
2005 (strip_whitespace): Constify.
2006 (func_if): Constify.
2007 * expand.c (expand_argument): Constify.
2009 2003-01-29 Paul D. Smith <psmith@gnu.org>
2011 Fix bug # 2169, also reported by other people on various systems.
2013 * make.h: Some systems, such as Solaris and PTX, do not fully
2014 implement POSIX-compliant SA_RESTART functionality; important
2015 system calls like stat() and readdir() can still fail with EINTR
2016 even if SA_RESTART has been set on the signal handler. So,
2017 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2018 EINTR for system calls which return -1 or 0 (NULL), respectively,
2020 Also, remove the old atomic_stat()/atomic_readdir() and
2021 HAVE_BROKEN_RESTART handling.
2023 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2025 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2026 * remake.c (touch_file): Ditto.
2028 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2029 * read.c (construct_include_path): Ditto.
2030 * remake.c (name_mtime): Ditto.
2031 * vpath.c (selective_vpath_search): Ditto.
2032 * dir.c (find_directory): Ditto.
2033 (local_stat): Ditto.
2034 (find_directory): Use ENULLLOOP() to wrap opendir().
2035 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2037 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2038 atomic_readdir() handling.
2040 2003-01-22 Paul D. Smith <psmith@gnu.org>
2042 * function.c (func_call): Fix Bug #1744. If we're inside a
2043 recursive invocation of $(call ...), mask any of the outer
2044 invocation's arguments that aren't used by this one, so that this
2045 invocation doesn't "inherit" them accidentally.
2047 2002-12-05 Paul D. Smith <psmith@gnu.org>
2049 * function.c (subst_expand): Valery Khamenia reported a
2050 pathological performance hit when doing substitutions on very
2051 large values with lots of words: turns out we were invoking
2052 strlen() a ridiculous number of times. Instead of having each
2053 call to sindex() call strlen() again, keep track of how much of
2054 the text we've seen and pass the length to sindex().
2056 2002-11-19 Paul D. Smith <psmith@gnu.org>
2058 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2061 2002-11-16 Paul D. Smith <psmith@gnu.org>
2063 * NMakefile.template (OBJS): Add hash.c object file.
2064 * SMakefile.template (srcs): Ditto.
2065 * Makefile.ami (objs): Ditto.
2066 * build_w32.bat: Ditto.
2068 * Makefile.DOS.template: Remove extra dependencies.
2070 2002-10-25 Paul D. Smith <psmith@gnu.org>
2072 * expand.c (install_variable_buffer): New function. Install a new
2073 variable_buffer context and return the previous one.
2074 (restore_variable_buffer): New function. Free the current
2075 variable_buffer context and put a previously saved one back.
2076 * variable.h: Prototypes for {install,restore}_variable_buffer.
2077 * function.c (func_eval): Push a new variable_buffer context
2078 before we eval, then restore the old one when we're done.
2081 * read.c (install_conditionals): New function. Install a new
2082 conditional context and return the previous one.
2083 (restore_conditionals): New function. Free the current
2084 conditional context and put a previously saved one back.
2085 (eval): Use the {install,restore}_conditionals for "include"
2087 (eval_buffer): Use {install,restore}_conditionals to preserve the
2088 present conditional state before we evaluate the buffer.
2091 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2093 (Recursion): Add a variable index entry for CURDIR.
2095 * README.cvs: Update to appropriate versions.
2096 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2097 don't need to copy loadavg.c: automake is smart enough to create
2098 it for me. Still have a bug in automake related to ansi2knr tho.
2100 2002-10-14 Paul D. Smith <psmith@gnu.org>
2102 * remake.c (notice_finished_file): Only touch targets if they have
2103 at least one command (as per POSIX). Resolve Bug #1418.
2105 * *.c: Convert to using ANSI C-style function definitions.
2106 * Makefile.am: Enable the ansi2knr feature of automake.
2107 * configure.in: ditto.
2109 2002-10-13 Paul D. Smith <psmith@gnu.org>
2111 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2112 for automatic variable values like $^, etc. In the case of very
2113 large lists of prerequisites this causes problems. Instead reuse
2114 a static buffer (resizeable) for each variable.
2116 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2117 target-specific variable definitions. Check for it and set an
2119 (record_target_var): Set the export field to v_export if the
2120 "exported" flag is set.
2121 * doc/make.texi (Target-specific): Document the ability to use
2124 * doc/make.texi: Change the name of the section on automatic
2125 variables from "Automatic" to "Automatic Variables". Added text
2126 clarifying the scope of automatic variables.
2128 2002-10-04 Paul D. Smith <psmith@gnu.org>
2130 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2132 (record_files): Ditto.
2134 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2135 the search for the '=' to only within the enclosing parens.
2137 2002-10-03 Paul D. Smith <psmith@gnu.org>
2139 Version 3.80 released.
2141 * dir.c: Change hash functions to use K&R function definition style.
2142 * function.c: Ditto.
2144 * variable.c: Ditto.
2146 Update to automake 1.7.
2148 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2149 (pdf): Remove this target as automake now provides one.
2151 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2153 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2155 * makefile.com: Updates for GNU make 3.80.
2156 * makefile.vms: Ditto.
2158 2002-09-23 Paul D. Smith <psmith@gnu.org>
2160 * read.c (enum make_word_type): Remove w_comment.
2161 (get_next_mword): Don't treat comment characters as special; where
2162 this function is used we will never see a comment (it's stripped
2163 before we get here) and treating comments specially means that
2164 targets like "foo\#bar" aren't handled properly.
2166 2002-09-18 Paul D. Smith <psmith@gnu.org>
2168 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2170 * read.c (eval): Expansion of arguments to export/unexport was
2171 ignoring all arguments after the first one. Change the algorithm
2172 to expand the whole line once, then parse the results.
2174 2002-09-17 Paul D. Smith <psmith@gnu.org>
2176 Fix Bug #940 (plus another bug I found while looking at this):
2178 * read.c (record_target_var): enter_file() will add a new entry if
2179 it's a double-colon target: we don't want to do that in this
2180 situation. Invoke lookup_file() and only enter_file() if it does
2181 not already exist. If the file we get back is a double-colon then
2182 add this variable to the "root" double-colon target.
2184 * variable.c (initialize_file_variables): If this file is a
2185 double-colon target but is not the "root" target, then initialize
2186 the root and make the root's variable list the parent of our
2189 2002-09-13 Paul D. Smith <psmith@gnu.org>
2191 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2193 * hash.c (round_up_2): Get rid of a warning.
2195 2002-09-12 Paul D. Smith <psmith@gnu.org>
2197 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2198 so it doesn't complain about getloadavg.c.
2200 * commands.c (set_file_variables): Make sure we always alloca() at
2201 least 1 character for the value of $? (for '\0').
2203 2002-09-11 Paul D. Smith <psmith@gnu.org>
2205 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2206 macro to use RESULT instead of the incorrect _RESULT_.
2208 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2209 and atomic_readdir(). We need to #include dirent.h to get this to
2211 * misc.c (atomic_readdir): Fix typos.
2213 2002-09-10 Paul D. Smith <psmith@gnu.org>
2215 * read.c (eval): Expand variable lists given to export and
2216 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2217 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2219 * doc/make.texi (Variables/Recursion): Document this.
2220 (Conditional Syntax): And here.
2222 2002-09-09 Paul D. Smith <psmith@gnu.org>
2224 * configure.in: Check for memmove().
2226 2002-09-07 Paul D. Smith <psmith@gnu.org>
2228 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2229 Michael Sterrett <msterret@coat.com> reports that while it has
2230 SA_RESTART, it does not work properly.
2232 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2233 that invokes stat() and loops to do it again if it returns EINTR.
2234 (atomic_readdir): Ditto, with readdir().
2236 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2237 and readdir() to atomic_stat() and atomic_readdir().
2239 2002-09-04 Paul D. Smith <psmith@gnu.org>
2241 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2242 reports that GNU make sometimes doesn't recognize that targets can
2243 be made, when directories can be created as prerequisites. He
2244 reports that changing the order of predicates in the DEP->changed
2245 flag test so that lookup_file() is always performed, solves this
2248 2002-08-08 Paul D. Smith <psmith@gnu.org>
2250 * configure.in: Require a newer version of gettext.
2252 * misc.c (perror_with_name): Translate the format string (for
2253 right-to-left language support).
2254 (pfatal_with_name): Ditto.
2256 * main.c: Create a static array of strings to store the usage
2257 text. This is done to facilitate translations.
2258 (struct command_switch): Remove argdesc and description fields.
2259 (switches): Remove values for obsolete fields.
2260 (print_usage): Print each element of the usage array.
2262 * hash.c: Change function definitions to be K&R style.
2264 2002-08-02 Paul D. Smith <psmith@gnu.org>
2266 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2267 this one because it's too hard to get right. We'll look at it for
2269 * main.c (main): Don't create the .TARGETS variable.
2270 * variable.c (handle_special_var): Don't handle .TARGETS.
2272 2002-08-01 Paul D. Smith <psmith@gnu.org>
2274 * main.c (switches): Add a new option, -B (--always-make). If
2275 specified, make will rebuild all targets that it encounters even
2276 if they don't appear to be out of date.
2277 (always_make_flag): New flag.
2278 * make.h: Extern always_make_flag.
2279 * remake.c (update_file_1): Check always_make_flag; if it's set we
2280 will always rebuild any target we can, even if none of its
2281 prerequisites are newer.
2284 * doc/make.texi (Shell Function): Make it clear that make
2285 variables marked as "export" are not passed to instances of the
2288 Add new introspection variable .VARIABLES and .TARGETS.
2290 * variable.c (handle_special_var): New function. If the variable
2291 reference passed in is "special" (.VARIABLES or .TARGETS),
2292 calculate the new value if necessary. .VARIABLES is handled here:
2293 walk through the hash of defined variables and construct a value
2294 which is a list of the names. .TARGETS is handled by
2295 build_target_list().
2296 (lookup_variable): Invoke handle_special_var().
2297 * file.c (build_target_list): Walk through the hask of known files
2298 and construct a list of the names of all the ones marked as
2300 * main.c (main): Initialize them to empty (and as simple variables).
2301 * doc/make.texi (Special Variables): Document them.
2302 * NEWS: Mention them.
2304 * variable.h (struct variable): Add a new flag "exportable" which
2305 is true if the variable name is valid for export.
2306 * variable.c (define_variable_in_set): Set "exportable" when a new
2307 variable is defined.
2308 (target_environment): Use the "exportable" flag instead of
2309 re-checking the name here... an efficiency improvement.
2311 2002-07-31 Paul D. Smith <psmith@gnu.org>
2313 * config.h-vms.template: Updates to build on VMS. Thanks to
2314 Brian_Benning@aksteel.com for helping verify the build.
2315 * makefile.com: Build the new hash.c file.
2316 * hash.h: Use strcpmi(), not stricmp(), in the
2317 HAVE_CASE_INSENSITIVE_FS case.
2319 2002-07-30 Paul D. Smith <psmith@gnu.org>
2321 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2322 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2323 Reported by <Brian_Benning@aksteel.com>.
2325 2002-07-10 Paul D. Smith <psmith@gnu.org>
2327 * variable.c (pop_variable_scope): Remove variable made unused by
2328 new hash infrastructure.
2329 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2330 comparisons as well as name comparisons.
2331 * variable.h: Add a prototype for new hash_init_function_table().
2332 * file.c (lookup_file): Remove variables made unused by new hash
2334 * dir.c (directory_contents_hash_2): Missing return of hash value.
2335 (dir_contents_file_exists_p): Remove variables made unused by new
2336 hash infrastructure.
2339 Installed Greg McGary's integration of the hash functions from the
2340 GNU id-utils package:
2342 2002-07-10 Greg McGary <greg@mcgary.org>
2344 * scripts/functions/filter-out: Add literals to to the
2345 pattern space in order to add complexity, and trigger
2346 use of an internal hash table. Fix documentation strings.
2347 * scripts/targets/INTERMEDIATE: Reverse order of files
2348 passed to expected `rm' command.
2350 2002-07-10 Greg McGary <greg@mcgary.org>

2442 2002-07-10 Paul D. Smith <psmith@gnu.org>
2444 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2445 prerequisite list. A real SysV make will expand the entire
2446 prerequisites list _twice_: we don't do that as it's a big
2447 backward-compatibility problem. We only replace those specific
2450 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2451 references left in the list of prerequisites. Check for .POSIX as
2452 we record targets, so we can disable non-POSIX behavior while
2453 reading makefiles as well as running them.
2454 (eval): Check the prerequisite list to see if we have anything
2455 that looks like a SysV prerequisite variable reference.
2457 2002-07-09 Paul D. Smith <psmith@gnu.org>
2459 * doc/make.texi (Prerequisite Types): Add a new section describing
2460 order-only prerequisites.
2462 * read.c (uniquize_deps): If we have the same file as both a
2463 normal and order-only prereq, get rid of the order-only prereq,
2464 since the normal one supersedes it.
2466 2002-07-08 Paul D. Smith <psmith@gnu.org>
2468 * AUTHORS: Added Greg McGary to the AUTHORS file.
2469 * NEWS: Blurbed order-only prerequisites.
2470 * file.c (print_file): Show order-only deps properly when printing
2473 * maintMakefile: Add "update" targets for wget'ing the latest
2474 versions of various external files. Taken from Makefile.maint in
2477 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2478 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2480 2002-07-07 Paul D. Smith <psmith@gnu.org>
2482 * po/*.po: Remove. We'll use wget to retrieve them at release
2485 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2486 rather than a shell you get an exception. Make sure we look up
2487 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2489 * remake.c (notice_finished_file): Fix handling of -t flag.
2490 Patch provided by Henning Makholm <henning@makholm.net>.
2492 * implicit.c (pattern_search): Some systems apparently run short
2493 of stack space, and using alloca() in this function caused an
2494 overrun. I modified it to use xmalloc() on the two variables
2495 which seemed like they might get large. Fixes Bug #476.
2497 * main.c (print_version): Update copyright notice to conform with
2499 (print_usage): Update help output.
2501 * function.c (func_eval): Create a new make function, $(eval
2502 ...). Expand the arguments, put them into a buffer, then invoke
2503 eval_buffer() on the resulting string.
2504 (func_quote): Create a new function, $(quote VARNAME). Inserts
2505 the value of the variable VARNAME without expanding it any
2508 * read.c (struct ebuffer): Change the linebuffer structure to an
2509 "eval buffer", which can be either a file or a buffer.
2510 (eval_makefile): Move the code in the old read_makefile() which
2511 located a makefile into here: create a struct ebuffer with that
2512 information. Have it invoke the new function eval() with that
2514 (eval_buffer): Create a new function that creates a struct ebuffer
2515 that holds a string buffer instead of a file. Have it invoke
2516 eval() with that ebuffer.
2517 (eval): New function that contains the guts of the old
2518 read_makefile() function: this function parses makefiles. Obtains
2519 data to parse from the provided ebuffer. Some modifications to
2520 make the flow of the function cleaner and clearer. Still could
2521 use some work here...
2522 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2523 contents of the define/endef variable from the ebuffer.
2524 (readstring): Read the next line from a string-style ebuffer.
2525 (readline): Read the next line from an ebuffer. If it's a string
2526 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2529 * dep.h (eval_buffer): Prototype eval_buffer();
2531 * variable.c (do_variable_definition): Make sure that all
2532 non-target-specific variables are registered in the global set.
2533 If we're invoked from an $(eval ...) we might be inside a $(call
2534 ...) or other function which has pushed a variable scope; we still
2535 want to define our variables from evaluated makefile code in the
2538 2002-07-03 Greg McGary <greg@mcgary.org>
2540 * dep.h (struct dep) [ignore_mtime]: New member.
2541 [changed]: convert to a bitfield.
2542 * implicit.c (pattern_search): Zero ignore_mtime.
2543 * main.c (main, handle_non_switch_argument): Likewise.
2544 * rule.c (convert_suffix_rule): Likewise.
2545 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2546 (read_makefile): Parse '|' in prerequisite list.
2547 (uniquize_deps): Consider ignore_mtime when comparing deps.
2548 * remake.c (update_file_1, check_dep): Don't force remake for
2549 dependencies that have d->ignore_mtime.
2550 * commands.c (FILE_LIST_SEPARATOR): New constant.
2551 (set_file_variables): Don't include a
2552 prerequisite in $+, $^ or $? if d->ignore_mtime.
2555 2002-06-18 Paul D. Smith <psmith@gnu.org>
2557 * make.texinfo: Updates for next revision. New date/rev/etc.
2558 Recreate all Info menus. Change license on the manual to the GNU
2559 Free Documentation License. A number of typos.
2560 (Variables Simplify): Don't use "-" before it's defined.
2561 (Automatic Prerequisites): Rewrite the target example to work
2562 properly if the compile fails. Remove incorrect comments about
2563 how "set -e" behaves.
2564 (Text Functions): Move the "word", "wordlist", "words", and
2565 "firstword" functions here, from "File Name Functions".
2566 * make-stds.texi: Update from latest GNU version.
2567 * fdl.texi: (created) Import the latest GNU version.
2569 2002-06-06 Paul D. Smith <psmith@gnu.org>
2571 * variable.c (do_variable_definition): New function: extract the
2572 part of try_variable_definition() that actually sets the value
2573 into a separate function.
2574 (try_variable_definition): Call do_variable_definition() after
2575 parsing the variable definition string.
2576 (define_variable_in_set): Make the name argument const.
2578 * variable.h (enum variable_flavor): Make public.
2579 (do_variable_definition): Create prototype.
2581 * read.c (read_all_makefiles): Create a new built-in variable,
2583 (read_makefile): Add each makefile read in to this variable value.
2585 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2587 * Makefile.DOS.template: Tweak according to changes in the
2588 distribution. Add back the dependencies of *.o files.
2590 * configh.dos.template: Synchronize with config.h.in.
2592 2002-05-09 Paul D. Smith <psmith@gnu.org>
2594 * file.c (file_timestamp_now): Use K&R function declaration.
2596 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2597 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2598 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2599 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2600 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2601 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2602 nlist.n_name is a pointer rather than an array.
2604 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2605 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2606 * configure.in: Use it instead of the old version.
2608 * main.c (main): Prefer setvbuf() to setlinebuf().
2610 2002-05-08 Paul D. Smith <psmith@gnu.org>
2612 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2613 (loadavg_LDADD): Ditto.
2615 2002-04-29 Paul D. Smith <psmith@gnu.org>
2617 * expand.c (recursively_expand_for_file): Rename
2618 recursively_expand() to recursively_expand_for_file() and provide
2619 an extra argument, struct file. If the argument is provided, set
2620 the variable scope to that of the file before expanding.
2621 * variable.h (recursively_expand): Make this a macro that invokes
2622 recursively_expand_for_file() with a NULL file pointer.
2623 * variable.c (target_environment): Call the renamed function and
2624 provide the current file context.
2625 Fixes Debian bug #144306.
2627 2002-04-28 Paul D. Smith <psmith@gnu.org>
2629 Allow $(call ...) user-defined variables to be self-referencing
2630 without throwing an error. Allows implementation of transitive
2631 closures, among other possibly useful things.
2632 Requested by: Philip Guenther <guenther@sendmail.com>
2634 * variable.h (struct variable): Add a new field: exp_count, and
2635 new macros to hold its size and maximum value.
2636 (warn_undefined): Make this a macro.
2637 * variable.c (define_variable_in_set): Initialize it.
2638 * expand.c (recursively_expand): If we detect recursive expansion
2639 of a variable, check the exp_count field. If it's greater than 0
2640 allow the recursion and decrement the count.
2641 (warn_undefined): Remove this (now a macro in variable.h).
2642 * function.c (func_call): Before we expand the user-defined
2643 function, modify its exp_count field to contain the maximum
2644 number of recursive calls we'll allow. After the call, reset it
2647 2002-04-21 Paul D. Smith <psmith@gnu.org>
2649 Modified to use latest autoconf (2.53), automake (1.6.1), and
2650 gettext (0.11.1). We're using gettext's new "external" support,
2651 to avoid including libintl source with GNU make.
2653 * README.cvs: New file. Explain how to build GNU make from CVS.
2655 * configure.in: Modify checking for the system glob library.
2656 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2657 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2658 etc. will manage it correctly). Set an automake conditional
2659 USE_LOCAL_GLOB to decide whether to compile the glob library.
2661 * getloadavg.c (main): Include make.h in the "TEST" program to
2664 * Makefile.am: Remove special rules for loadavg. Replace them
2665 with Automake capabilities for building extra programs.
2667 * signame.c: This file does nothing if the system provide
2668 strsignal(). If not, it implements strsignal(). If the system
2669 doesn't define sys_siglist, then we make our own; otherwise we use
2671 * signame.h: Removed.
2673 * main.c (main): No need to invoke signame_init(). Update copyright.
2675 * ABOUT-NLS: Removed.
2676 * gettext.c: Removed.
2677 * gettext.h: Get a simplified copy from the gettext package.
2679 * i18n/*.po: Moved to po/.
2682 * config/*: Created. Contains package configuration helper files.
2683 * config.guess, config.sub: Moved to config directory.
2685 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2686 Rework to use new-style autoconf features. Use the "external"
2687 mode for gettext. Make the build.sh config file conditional on
2688 whether build.sh.in exists, to avoid autoconf errors.
2689 * acinclude.m4: Removed almost all macros as being obsolete.
2690 Rewrote remaining macros to use AC_DEFINE.
2691 * acconfig.h: Removed.
2693 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2694 conditional to handle customs support. Remove special handling
2697 2002-04-20 Paul D. Smith <psmith@gnu.org>
2699 * function.c (func_call): Don't mark the argument variables $1,
2700 etc. as recursive. They've already been fully expanded so
2701 there's no need to do it again, and doing so strips escaped $'s.
2702 Reported by Sebastian Glita <glseba@yahoo.com>.
2704 * remake.c (notice_finished_file): Walk through double-colon
2705 entries via the prev field, not the next field!
2706 Reported by Greg McGary <greg@mcgary.org>.
2708 * main.c (main): If the user specifies -q and asks for a specific
2709 target which is a makefile, we got an assert. In that case it
2710 turns out we should continue normally instead.
2712 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2714 * i18n/he.po: Installed a new translation.
2716 2002-01-07 Paul D. Smith <psmith@gnu.org>
2718 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2720 2001-12-04 Paul D. Smith <psmith@gnu.org>
2722 * i18n/ja.po: Installed an updated translation.
2724 2001-09-06 Paul Eggert <eggert@twinsun.com>
2726 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2727 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2729 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2731 (main): Get rid of any avoidable limit on stack size.
2733 2001-09-04 Paul D. Smith <psmith@gnu.org>
2735 * i18n/da.po: Installed an updated translation.
2737 2001-08-03 Paul D. Smith <psmith@gnu.org>
2739 * i18n/fr.po: Installed an updated translation.
2740 Resolves Debian bug #106720.
2742 2001-06-13 Paul D. Smith <psmith@gnu.org>
2744 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2747 2001-06-11 Paul D. Smith <psmith@gnu.org>
2749 * i18n/ko.po: Installed a new translation.
2751 2001-05-06 Paul D. Smith <psmith@gnu.org>
2753 Modify the EINTR handling.
2755 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2756 the way in which we manage the file descriptor/signal handler race
2757 trap to be more efficient.
2759 2001-05-06 Paul Eggert <eggert@twinsun.com>
2761 Restart almost all system calls that are interrupted, instead
2762 of worrying about EINTR. The lone exception is the read() for
2765 * configure.in (HAVE_SA_RESTART): New macro.
2766 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2767 * main.c (main): Use SA_RESTART instead of the old,
2768 nonstandard SA_INTERRUPT.
2770 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2771 * main.c (bsd_signal): New function or macro,
2772 if the implementation doesn't supply it.
2773 (The bsd_signal function will be in POSIX 1003.1-200x.)
2774 (HANDLESIG): Remove.
2775 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2777 * make.h (EINTR_SET): Remove.
2778 (SA_RESTART): New macro.
2780 * arscan.c (ar_member_touch): Don't worry about EINTR.
2781 * function.c (func_shell): Likewise.
2782 * job.c (reap_children, free_child, new_job): Likewise.
2783 * main.c (main): Likewise.
2784 * remake.c (touch_file, name_mtime): Likewise.
2786 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2787 if fstat failed with errno!=EINTR, the error was ignored.
2789 * job.c (set_child_handler_action_flags): New function.
2790 (new_job): Use it to temporarily clear the SIGCHLD action flags
2791 while reading the token.
2793 2001-05-02 Paul D. Smith <psmith@gnu.org>
2795 * job.c (start_job_command): Don't add define/endef per-line flags
2796 to the top-level flags setting.
2798 2001-04-03 Paul D. Smith <psmith@gnu.org>
2800 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2801 bit on error, so check for odd return values, not non-0 return
2803 (VMS_get_member_info): Calculate the timezone differences correctly.
2804 Reported by John Fowler <jfowler@nyx.net>.
2807 2001-03-14 Paul D. Smith <psmith@gnu.org>
2809 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2810 value before invoking define_variable().
2811 Reported by John Fowler <jfowler@nyx.net>.
2813 2001-02-07 Paul D. Smith <psmith@gnu.org>
2815 * read.c (record_target_var): If we reset the variable due to a
2816 command-line variable setting overriding it, turn off the "append"
2819 2001-01-17 Paul D. Smith <psmith@gnu.org>
2821 * variable.c (lookup_variable) [VMS]: When getting values from the
2822 environment, allocate enough space for the _value_ plus escapes,
2823 not enough space for the name plus escapes :-/.
2824 Reported by John Fowler <jfowler@nyx.net>.
2826 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2827 warnings that make generates, so it doesn't look like an error.
2828 Reported by Karl Berry <karl@gnu.org>.
2831 Fix for PR/2020: Rework appended target-specific variables. I'm
2832 fairly confident this algorithm is finally correct.
2834 * expand.c (allocated_variable_append): Rewrite. Instead of
2835 expanding each appended variable then adding all the expanded
2836 strings together, we append all the unexpanded values going up
2837 through the variable set contexts, then expand the final result.
2838 This behaves just like non-target-specific appended variable
2839 values, while the old way didn't in various corner cases.
2840 (variable_append): New function: recursively append the unexpanded
2841 value of a variable, walking from the outermost variable scope to
2843 * variable.c (lookup_variable): Remove the code that looked up the
2844 variable set list if the found variable was "append". We don't
2846 (lookup_variable_in_set): Make this non-static so we can use it
2848 (try_variable_definition): Use lookup_variable_in_set() rather
2849 than faking out current_variable_set_list by hand (cleanup).
2850 * variable.h: Add a prototype for the now non-static
2851 lookup_variable_in_set().
2853 2000-11-17 Paul D. Smith <psmith@gnu.org>
2855 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2856 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2857 before throwing a fit.
2859 2000-11-17 Paul D. Smith <psmith@gnu.org>
2861 * read.c (readline): CRLF calculations had a hole, if you hit the
2862 buffer grow scenario just right. Reworked the algorithm to avoid
2863 the need for len or lastlen at all. Problem description with
2864 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2866 2000-10-24 Paul D. Smith <psmith@gnu.org>
2868 * gettext.c (SWAP): Declare this with the prototype, otherwise
2869 some systems don't work (non-32-bit? Reported for Cray T3E).
2870 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2872 2000-10-05 Paul D. Smith <psmith@gnu.org>
2874 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2875 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2877 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2879 2000-09-22 Paul D. Smith <psmith@gnu.org>
2881 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2882 parts of the real gettext.h here, and we expect to really include
2883 the real gettext.h later. If we keep this #define, it's ignored.
2885 2000-09-21 Paul D. Smith <psmith@gnu.org>
2887 * main.c (log_working_directory): Rework the text to use complete
2888 sentences, to make life simpler for the translators.
2890 2000-08-29 Paul D. Smith <psmith@gnu.org>
2892 * file.c (remove_intermediates): Print a debug message before we
2893 remove intermediate files, so the user (if she uses -d) knows
2896 2000-08-21 Paul D. Smith <psmith@gnu.org>
2898 * variable.c (try_variable_definition): Change how we handle
2899 target-specific append variable defns: instead of just setting the
2900 value, expand it as an append _but_ only within the current
2901 target's context. Otherwise we lose all but the last value if the
2902 variable is appended more than once within the current target
2903 context. Fixes PR/1831.
2905 2000-08-16 Paul D. Smith <psmith@gnu.org>
2907 * function.c (func_shell): Nul-terminate the buffer before
2908 printing an exec error message (just in case it's not!).
2909 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2911 2000-07-25 Paul D. Smith <psmith@gnu.org>
2913 * job.c (construct_command_argv_internal): Add "~" to the list of
2914 sh_chars[] which disallow optimizing out the shell call.
2916 2000-07-23 Paul Eggert <eggert@twinsun.com>
2918 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2919 supersedes --disable-nsec-timestamps.
2920 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2921 * README: Remove --disable-nsec-timestamps.
2923 * filedef.h (struct file.low_resolution_time): New member.
2924 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2925 * remake.c (update_file_1):
2926 Avoid spurious rebuilds due to low resolution time stamps,
2927 generalizing the earlier code that applied only to archive members.
2928 (f_mtime): Archive members always have low resolution time stamps.
2930 * configure.in: Remove --disable-nsec-timestamps, as this has
2931 been superseded by .LOW_RESOLUTION_TIME.
2933 2000-07-23 Paul Eggert <eggert@twinsun.com>
2935 * configure.in (enable_nsec_timestamps): Renamed from
2936 make_cv_nsec_timestamps, since enable/disable options
2937 shouldn't be cached.
2939 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2940 and Paul Eggert <eggert@twinsun.com>
2942 * file.c (file_timestamp_now):
2943 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2944 so that clock_gettime is not linked unless needed.
2946 * filedef.h (FILE_TIMESTAMP_HI_RES):
2947 Remove definition; "configure" now does this.
2949 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2950 to before high resolution file timestamp check,
2951 since that check now uses uintmax_t.
2952 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2953 high resolution file timestamps.
2954 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2955 so that we don't link in clock_gettime unnecessarily.
2957 2000-07-17 Paul D. Smith <psmith@gnu.org>
2959 * i18n/ja.po: New version of the translation file.
2961 2000-07-07 Paul D. Smith <psmith@gnu.org>
2963 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2964 the offset calculation.
2965 (name_mtime): Replace EINTR test with EINTR_SET macro.
2967 2000-07-07 Paul Eggert <eggert@twinsun.com>
2971 * remake.c (update_file_1):
2972 Avoid spurious rebuilds of archive members due to their
2973 timestamp resolution being only one second.
2974 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2975 the clock's resolution being lower than file timestamps'.
2976 When warning about future timestamps, report only the discrepancy,
2977 not the absolute value of the timestamp and the current time.
2979 * file.c (file_timestamp_now): New arg RESOLUTION.
2980 * filedef.h (file_timestamp_now): Likewise.
2981 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2983 2000-07-05 Paul D. Smith <psmith@gnu.org>
2985 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2986 to listp. Fixes PR/1793.
2988 2000-06-26 Paul Eggert <eggert@twinsun.com>
2990 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2992 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2994 * remake.c (f_mtime): Remove unused var memtime.
2996 2000-06-25 Martin Buchholz <martin@xemacs.org>
2998 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2999 Ran spell-check on make.texinfo.
3001 2000-06-23 Paul D. Smith <psmith@gnu.org>
3003 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3004 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3005 * make.h: Define these macros.
3007 * Version 3.79.1 released.
3009 * configure.in: Add a new option, --disable-nsec-timestamps, to
3010 avoid using sub-second timestamps on systems that support it. It
3011 can lead to problems, e.g. if your makefile relies on "cp -p".
3012 * README.template: Document the issue with "cp -p".
3014 * config.guess, config.sub: Updated.
