3 A new internal capability: the string cache is a read-only cache
4 of strings, with a hash table interface for fast lookup. Nothing
5 in the cache will ever be freed, so there's no need for reference
6 counting, etc. This is the beginning of a full solution for
7 Savannah bug #15182, but for now we only store makefile names here.
9 * strcache.c: New file. Implement a read-only string cache.
10 * make.h: Add prototypes for new functions.
11 * main.c (initialize_global_hash_tables): Initialize the string cache.
12 (print_data_base): Print string cache stats.
13 * read.c (eval_makefile): Use the string cache to store makefile
14 names. Rewrite the string allocation to be sure we free everything.
16 2006-02-09 Paul D. Smith <psmith@gnu.org>
18 * function.c (func_or): Implement a short-circuiting OR function.
19 (func_and): Implement a short-circuiting AND function.
20 (function_table_init): Update the table with the new functions.
21 * doc/make.texi (Conditional Functions): Changed the "if" section
22 to one on general conditional functions. Added documentation for
23 $(and ...) and $(or ...) functions.
24 * NEWS: Note new $(and ...) and $(or ...) functions.
26 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
28 * job.h (struct child): Add dontcare bitfield.
29 * job.c (new_job): Cache dontcare flag.
30 * job.c (reap_children): Use cached dontcare flag instead of the
31 one in struct file. Fixes Savannah bug #15641.
33 2006-02-06 Paul D. Smith <psmith@gnu.org>
35 * vpath.c (selective_vpath_search): If the file we find has a
36 timestamp from -o or -W, use that instead of the real time.
37 * remake.c (f_mtime): If the mtime is a special token from -o or
38 -W, don't overwrite it with the real mtime.
39 Fixes Savannah bug #15341.
41 Updates from Markus Mauhart <qwe123@chello.at>:
43 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
44 (process_signal, process_last_err, process_exit_code): Manage
45 invalid handle values.
46 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
47 manage invalid handles; remove them.
48 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
49 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
50 * README.cvs: Updates for building from CVS.
52 2006-02-05 Paul D. Smith <psmith@gnu.org>
54 * file.c (enter_file): Keep track of the last double_colon entry,
55 to avoid walking the list every time we want to add a new one.
56 Fixes Savannah bug #15533.
57 * filedef.h (struct file): Add a new LAST pointer.
59 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
60 the comparison. For 64-bits systems the result of the subtraction
61 might not fit into an int. Use comparison instead.
62 Fixes Savannah bug #15534.
64 * doc/make.texi: Update the chapter on writing commands to reflect
65 the changes made in 3.81 for backslash/newline and SHELL handling.
67 2006-02-01 Paul D. Smith <psmith@gnu.org>

83 * prepare_w32.bat: Remove this file from the distribution.
85 2006-01-21 Eli Zaretskii <eliz@gnu.org>
87 * remake.c (update_goal_chain): Set g->changed instead of
88 incrementing it, as it is only 8-bit wide, and could overflow if
89 many commands got started in update_file.
91 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
93 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
95 (process_wait_for_any_private): Change dimension of handles[]
96 array to MAXIMUM_WAIT_OBJECTS.
97 (process_used_slots): New function.
98 (process_register): Don't register more processes than the
99 available number of slots.
100 (process_easy): Don't start new processes if all slots are used up.
102 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
103 are already more children than sub_proc.c can handle, behave as if
104 the load were too high.
105 (start_job_command): Fix a typo in error message when process_easy
108 2006-01-14 Eli Zaretskii <eliz@gnu.org>
110 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
111 the shell is not sh.exe.
113 * job.c (create_batch_file): Renamed from create_batch_filename;
114 all callers changed. Don't close the temporary file; return its
115 file descriptor instead. New arg FD allows to return the file
117 (construct_command_argv_internal): Use _fdopen instead of fopen to
120 2006-01-04 Paul D. Smith <psmith@gnu.org>
122 * readme.vms: Updates for case-insensitive VMS file systems from
123 Hartmut Becker <Hartmut.Becker@hp.com>.

132 2006-01-03 Paul D. Smith <psmith@gnu.org>
134 * remake.c (update_file_1): Mark a prerequisite changed if it
137 * read.c (eval): Be sure to strip off trailing whitespace from the
138 prerequisites list properly. Also, initialize all fields in
139 struct dep when creating a new one.
141 2005-12-28 Paul D. Smith <psmith@gnu.org>
143 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
144 disable warnings for MSC.
145 Patch by Rob Tulloh <rtulloh@yahoo.com>.
147 2005-12-17 Eli Zaretskii <eliz@gnu.org>
149 * doc/make.texi (Execution): Add a footnote about changes in
150 handling of backslash-newline sequences. Mention the differences
151 on MS-DOS and MS-Windows.
153 * NEWS: More details about building the MinGW port and a pointer
154 to README.W32. Fix the section name that describes the new
155 backward-incompatible processing of backslash-newline sequences.
156 The special processing of SHELL set to "cmd" is only relevant to
157 MS-Windows, not MS-DOS.
159 2005-12-17 Eli Zaretskii <eliz@gnu.org>
161 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
162 to DWORD, to avoid compiler warnings.
163 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
164 use %ld in format, to avoid compiler warnings.

178 * read.c (record_target_var): Initialize variable's export field
179 with v_default instead of leaving it "initialized" by whatever
180 garbage happened to be on the heap.
182 2005-12-12 Paul D. Smith <psmith@gnu.org>
184 * make.1: Fix some display errors and document all existing options.
185 Patch provided by Mike Frysinger <vapier@gentoo.org>.
187 2005-12-11 Paul D. Smith <psmith@gnu.org>
189 * implicit.c (pattern_search): If 2nd expansion is not set for
190 this implicit rule, replace the pattern with the stem directly,
191 and don't re-expand the variable list. Along with the other
192 .SECONDEXPANSION changes below, fixes bug #13781.
194 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
196 * implicit.c (pattern_search): Mark other files that this rule
197 builds as targets so that they are not treated as intermediates
198 by the pattern rule search algorithm. Fixes bug #13022.
200 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
202 * remake.c (notice_finished_file): Propagate the change of
203 modification time to all the double-colon entries only if

218 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
220 2005-10-26 Paul Smith <psmith@gnu.org>
222 * read.c (record_files): Don't set deps flags if there are no deps.
223 * maintMakefile: We only need to build the templates when we are
224 creating a distribution, so don't do it for "all".
226 2005-10-24 Paul D. Smith <psmith@gnu.org>
228 Make secondary expansion optional: its enabled by declaring the
229 special target .SECONDEXPANSION.
231 * NEWS: Update information on second expansion capabilities.
232 * doc/make.texi (Secondary Expansion): Document the
233 .SECONDEXPANSION special target and its behavior.
234 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
235 prerequisite list was found in a static pattern rule.
236 (free_dep_chain): Declare a prototype.
237 * file.c (parse_prereqs): New function: break out some complexity
239 (expand_deps): If we aren't doing second expansion, replace % with
240 the stem for static pattern rules. Call the new function.
241 * filedef.h (parse_prereqs): Declare a prototype.
242 * implicit.c (pattern_search): Initialize the new staticpattern
244 * main.c (second_expansion): Declare a global variable to remember

248 * misc.c (free_dep_chain): New function: frees a struct dep list.
249 * read.c (read_all_makefiles): Initialize the staticpattern field.
250 (eval_makefile): Ditto.
251 (record_files): Check for the .SECONDEXPANSION target and set
252 second_expansion global if it's found.
253 Use the new free_dep_chain() instead of doing it by hand.
254 Set the staticpattern field for prereqs of static pattern targets.
256 2005-10-16 Paul D. Smith <psmith@gnu.org>
258 * main.c (main): Set CURDIR to be a file variable instead of a
259 default, so that values of CURDIR inherited from the environment
260 won't override the make value.
262 2005-09-26 Paul D. Smith <psmith@gnu.org>
264 * job.c (construct_command_argv_internal): If the line is empty
265 remember to free the temporary argv strings.
268 2005-09-16 Paul D. Smith <psmith@gnu.org>
270 * job.c (start_job_command): The noerror flag is a boolean (single
271 bit); set it appropriately.
272 Reported by Mark Eichin <eichin@metacarta.com>
274 2005-08-29 Paul D. Smith <psmith@gnu.org>
276 * function.c (func_error): On Windows, output from $(info ...)
277 seems to come in the wrong order. Try to force it with fflush().
279 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
281 * read.c (record_files): Move code that sets stem for static
282 pattern rules out of the if (!two_colon) condition so it is
283 also executed for two-colon rules. Fixes Savannah bug #13881.
285 2005-08-08 Paul D. Smith <psmith@gnu.org>
287 * make.h: Don't test that __STDC__ is non-0. Some compilers
288 (Windows for example) set it to 0 to denote "ISO C + extensions".
291 2005-08-07 Paul D. Smith <psmith@gnu.org>
293 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
294 conditional (slightly different version of a fix from Eli).
296 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
297 If make is running in parallel without -k and two jobs die in a
298 row, but not too close to each other, then make will quit without
299 waiting for the rest of the jobs to die.
301 * main.c (die): Don't reset err before calling reap_children() the
302 second time: we still want it to be in the error condition.
303 * job.c (reap_children): Use a static variable, rather than err,
304 to control whether or not the error message should be printed.
306 2005-08-06 Eli Zaretskii <eliz@gnu.org>
308 * w32/subproc/sub_proc.c: Include signal.h.
309 (process_pipe_io, process_file_io): Pass a pointer to a local
310 DWORD variable to GetExitCodeProcess. If the exit code is
311 CONTROL_C_EXIT, put SIGINT into pproc->signal.
313 * job.c [WINDOWS32]: Include windows.h.
314 (main_thread) [WINDOWS32]: New global variable.
315 (reap_children) [WINDOWS32]: Get the handle for the main thread
316 and store it in main_thread.
318 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
319 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
320 doing anything else. When we are done, close the main thread
321 handle and exit with status 130.
323 2005-07-30 Eli Zaretskii <eliz@gnu.org>
325 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
328 * main.c (find_and_set_default_shell): If found a DOSish shell,
329 set sh_found and the value of default_shell, and report the
330 findings in debug mode.
332 * job.c (construct_command_argv_internal): Check unixy_shell, not
333 no_default_sh_exe, to decide whether to use Unixy or DOSish
336 * README.W32: Update with info about the MinGW build.
338 * build_w32.bat: Support MinGW.
340 * w32/subproc/build.bat: Likewise.
342 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
345 * function.c (windows32_openpipe): Fix format strings for printing
348 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
350 (start_job_command): Fix format string for printing the result of
352 (start_job_command) [WINDOWS32]: Do not define.
353 (exec_command): Fix format string for printing HANDLE args.
355 * main.c (handle_runtime_exceptions): Fix sprintf format strings
356 to avoid compiler warnings.
357 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
358 (Note: some of these fixes were submitted independently by J. Grant)
360 2005-07-30 J. Grant <jg@jguk.org>
362 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
363 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
364 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
366 2005-07-15 Paul Smith <psmith@gnu.org>
368 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
369 we don't have a POSIX shell, then revert to the old
370 backslash-newline behavior (where they are stripped).
373 2005-07-08 Paul D. Smith <psmith@gnu.org>
375 * config.h.W32.template: Reorder to match the standard config.h,
376 for easier comparisons.
377 From J. Grant <jg@jguk.org>
379 * maintMakefile: Remove .dep_segment before overwriting it, in
380 case it's not writable or noclobber is set.
381 * expand.c (variable_expand_string): Cast result of pointer
382 arithmetic to avoid a warning.
383 * main.c (switches): Add full-fledged final initializer.
385 2005-07-06 Paul D. Smith <psmith@gnu.org>
387 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
388 * signame.c (strsignal): If we found _sys_siglist[] or
389 __sys_siglist[] use those instead of sys_siglist[].
390 From Albert Chin <china@thewrittenword.com>
392 2005-07-04 Paul D. Smith <psmith@gnu.org>
394 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
395 globfree(); set up to use the GNU versions.
396 From Martin Zinser <zinser@zinser.no-ip.info>
398 2005-07-03 Paul D. Smith <psmith@gnu.org>
400 From J. Grant <jg@jguk.org>:
402 * README.W32.template: Update the Windows and tested MSVC versions.
403 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
404 * w32/subproc/NMakefile (CFLAGS_any): Ditto.

406 * w32/subproc/build.bat: Ditto.
408 2005-06-28 Paul D. Smith <psmith@gnu.org>
410 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
411 declaration was checked but not present.
413 2005-06-27 Paul D. Smith <psmith@gnu.org>
415 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
416 to unsigned long. Fixes Savannah bug #13550.
418 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
419 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
420 Fixes Savannah bug #13551.
422 2005-06-26 Paul D. Smith <psmith@gnu.org>
424 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
425 it if ANSI_STRING is not set.
427 2005-06-25 Paul D. Smith <psmith@gnu.org>
429 * read.c (eval): If no filenames are passed to any of the
430 "include" variants, don't print an error.
431 * doc/make.texi (Include): Document this.
432 Fixes Savannah bug #1761.
434 * job.c (construct_command_argv_internal): Sanitize handling of
435 backslash/newline pairs according to POSIX: that is, keep the
436 backslash-newline in the command script, but remove a following
437 TAB character, if present. In the fast path, make sure that the
438 behavior matches what the shell would do both inside and outside
439 of quotes. In the slow path, quote the backslash and put a
440 literal newline in the string.
441 Fixes Savannah bug #1332.
442 * doc/make.texi (Execution): Document the new behavior and give
444 * NEWS: Make a note of the new behavior.
446 * make.h [WINDOWS32]: #include <direct.h>.
447 Fixes Savannah bug #13478.
449 * remake.c (name_mtime): If the stat() of a file fails and the -L
450 option was given and the file is a symlink, take the best mtime of
451 the symlink we can get as the mtime of the file and don't fail.
452 Fixes Savannah bug #13280.
454 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
455 If it's set, then don't stop on STOPCHARs or BLANKs if they're
456 inside a variable reference. Make this function static as it's
458 (eval): Call find_char_unquote() with IGNOREVARS set when we're
459 parsing an unexpanded line looking for semicolons.
460 Fixes Savannah bug #1454.
461 * misc.c (remove_comments): Move this to read.c and make it static
462 as it's only used there. Call find_char_unquote() with new arg.
463 * make.h: Remove prototypes for find_char_unquote() and
464 remove_comments() since they're static now.
466 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
467 its export flag and obtain its value. When we need to re-exec,
468 increment the value and add it into the environment.
469 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
470 * NEWS: Mention MAKE_RESTARTS.
471 * main.c (always_make_set): New variable. Change the -B option to
472 set this one instead.
473 (main): When checking makefiles, only set always_make_flag if
474 always_make_set is set AND the restarts flag is 0. When building
475 normal targets, set it IFF always_make_set is set.
476 (main): Avoid infinite recursion with -W, too: only set what-if
477 files to NEW before we check makefiles if we've never restarted
478 before. If we have restarted, set what-if files to NEW _after_ we
480 Fixes Savannah bug #7566:
482 2005-06-17 Paul D. Smith <psmith@gnu.org>
484 * default.c: Change VMS implicit rules to use $$$$ instead of $$
485 in the prerequisites list.
487 2005-06-12 Paul D. Smith <psmith@gnu.org>
489 Fix Savannah bug # 1328.
491 * configure.in: Check for atexit().
492 * misc.c (close_stdout): Test stdout to see if writes to it have
493 failed. If so, be sure to exit with a non-0 error code. Based on
494 code found in gnulib.
496 * main.c (main): Install close_stdout() with atexit().
498 2005-06-10 Paul D. Smith <psmith@gnu.org>
500 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
502 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
503 headers; make vmsWaitForChildren() static; extern vmsify().
504 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
505 Don't create child_execute_job() here (it's in vmsjobs.c).
506 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
508 2005-06-09 Paul D. Smith <psmith@gnu.org>
510 * variable.c (push_new_variable_scope): File variables point
511 directly to the global_setlist variable. So, inserting a new
512 scope in front of that has no effect on those variables: they
513 don't go through current_variable_set_list. If we're pushing a
514 scope and the current scope is global, push it "the other way" so
515 that the new setlist is in the global_setlist variable, and
516 next points to a new setlist with the global variable set.
517 (pop_variable_scope): Properly undo a push with the new
519 Fixes Savannah bug #11913.
521 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
523 * job.c (reap_children): Don't die of the command failed but
524 the dontcare flag is set. Fixes Savannah bug #13216.
526 * implicit.c (pattern_search): When creating a target from
527 an implicit rule match, lookup pattern target and set precious
528 flag in a newly created target. Fixes Savannah bug #13218.
530 2005-05-13 Paul D. Smith <psmith@gnu.org>
532 Implement "if... else if... endif" syntax.
534 * read.c (eval): Push all checks for conditional words ("ifeq",
535 "else", etc.) down into the conditional_line() function.
536 (conditional_line): Rework to allow "else if..." clause. New
537 return value -2 for lines which are not conditionals. The
538 ignoring flag can now also be 2, which means "already parsed a
539 true branch". If that value is seen no other branch of this
540 conditional can be considered true. In the else parsing if there
541 is extra text after the else, invoke conditional_line()
542 recursively to see if it's another conditional. If not, it's an
543 error. If so, raise the conditional value to this level instead
544 of creating a new conditional nesting level. Special check for
545 "else" and "endif", which aren't allowed on the "else" line.
546 * doc/make.texi (Conditional Syntax): Document the new syntax.
548 2005-05-09 Paul D. Smith <psmith@gnu.org>
550 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
551 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
552 recurses to the w32 directory, even on non-Windows systems. Use
553 the method suggested in the automake manual.
554 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
555 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
557 2005-05-07 Paul D. Smith <psmith@gnu.org>
559 * main.c (die): If we're dying with a fatal error (not that a
560 command has failed), write back any leftover tokens before we go.
562 * job.c (set_child_handler_action_flags): If there are jobs
563 waiting for the load to go down, set an alarm to go off in 1
564 second. This allows us to wake up from a potentially long-lasting
565 read() and start a new job if the load has gone down. Turn it off
567 (job_noop): Dummy signal handler function.
568 (new_job): Invoke it with the new semantics.
570 * docs/make.texi: Document secondary expansion. Various cleanups
573 2005-05-03 Paul D. Smith <psmith@gnu.org>
575 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
576 the targets which are to ultimately be made are called "goals";
577 see the GNU make manual. Also, MAKECMDGOALS, etc.
579 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
580 .DEFAULT_GOAL, and default_target_name to default_goal_name.
581 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
583 2005-05-02 Paul D. Smith <psmith@gnu.org>
585 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
586 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
587 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
588 functions to vmsjobs.c. #include it into jobs.c.
590 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
591 jobserver tokens. I found that this happens when an exported
592 recursive variable contains a $(shell ...) function reference: in
593 this situation we could "forget" to write back a token.
595 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
596 we have. It's not reliable to depend on the number of children in
597 our linked list so keep a separate count.
598 (new_job): Check jobserver_tokens rather than children &&
599 waiting_jobs. Increment jobserver_tokens when we get one.
600 (free_child): If jobserver_tokens is 0, internal error. If it's
601 >1, write a token back to the jobserver pipe (we don't write a
602 token for the "free" job). Decrement jobserver_tokens.
604 * main.c: Add variable master_job_slots.
605 (main): Set it to hold the number of jobs requested if we're the
606 master process, when using the jobserver.
607 (die): Sanity checks: first test jobserver_tokens to make sure
608 this process isn't holding any tokens we didn't write back.
609 Second, if master_job_slots is set count the tokens left in the
610 jobserver pipe and ensure it's the same as master_job_slots (- 1).
612 2005-04-24 Paul D. Smith <psmith@gnu.org>
614 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
615 with -l# can lose jobserver tokens, because waiting jobs are not
616 consulted properly when checking for the "free" token.
618 * job.c (free_child): Count waiting_jobs as having tokens.
619 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
620 handle jobs waiting for the load to drop.
622 2005-04-23 Paul D. Smith <psmith@gnu.org>
624 * main.c (main): Be careful to not core if a variable setting in
625 the environment doesn't contain an '='. This is illegal but can
626 happen in broken setups.
627 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
629 2005-04-12 Paul D. Smith <psmith@gnu.org>
631 The second expansion feature causes significant slowdown. Timing
632 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
633 read the makefile before the feature, to 11+s to do the same
634 operations after the feature. Additionally, memory usage
635 increased drastically. To fix this I added some intelligence that
636 avoids the overhead of the second expansion unless it's required.
638 * dep.h: Add a new boolean field, need_2nd_expansion.
640 * read.c (eval): When creating the struct dep for the target,
641 check if the name contains a "$"; if so set need_2nd_expansion to 1.
642 (record_files): If there's a "%" in a static pattern rule, it gets
643 converted to "$*" so set need_2nd_expansion to 1.
645 * file.c (expand_deps): Rework to be more efficient. Only perform
646 initialize_file_variables(), set_file_variables(), and
647 variable_expand_for_file() if the need_2nd_expansion is set.
649 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
650 (pattern_search): Ditto.
651 * main.c (handle_non_switch_argument): Ditto.
653 * read.c (read_all_makefiles): Ditto.
654 (eval_makefile): Ditto.
656 2005-04-07 Paul D. Smith <psmith@gnu.org>
658 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
659 * variable.c (sync_Path_environment): Ditto.
660 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
662 * main.c (main): Define the .FEATURES variable.
663 * NEWS: Announce .FEATURES.
664 * doc/make.texi (Special Variables): Document .FEATURES.
666 * remake.c (check_dep): If a file is .PHONY, update it even if
667 it's marked intermediate. Fixes Savannah bug #12331.
669 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
671 * file.c (expand_deps): Factor out the second expansion and
672 prerequisite line parsing logic from snap_deps().
674 * file.c (snap_deps): Use expand_deps(). Expand and parse
675 prerequisites of the .SUFFIXES special target first. Fixes
678 2005-03-13 Paul D. Smith <psmith@gnu.org>
680 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
683 2005-03-11 Paul D. Smith <psmith@gnu.org>
685 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
686 available, not undefined (from Earnie Boyd).
688 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
690 * implicit.c (pattern_search): Mark an intermediate target as
691 precious if it happened to be a prerequisite of some (other)
692 target. Fixes Savannah bug #12267.
694 2005-03-09 Paul D. Smith <psmith@gnu.org>
696 * read.c (eval_makefile): Add alloca(0).
697 (eval_buffer): Ditto.
699 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
701 * main.c (main): Use o_file instead of o_default when defining
702 the .DEFAULT_TARGET special variable.
703 * read.c (eval): Use define_variable_global() instead of
704 define_variable() when setting new value for the .DEFAULT_TARGET
705 special variable. Fixes Savannah bug #12266.
707 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
709 * imlicit.c (pattern_search): Mark files for which an implicit
710 rule has been found as targets. Fixes Savannah bug #12202.
712 2005-03-04 Paul D. Smith <psmith@gnu.org>
715 * doc/make.texi (Automatic Variables): Document $|.
717 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
719 * read.c (record_files): Instead of substituting % with
720 actual stem value in dependency list replace it with $*.
721 This fixes stem triple expansion bug.
723 * implicit.c (pattern_search): Copy stem to a separate
724 buffer and make it a properly terminated string. Assign
725 this buffer instead of STEM (which is not terminated) to
726 f->stem. Instead of substituting % with actual stem value
727 in dependency list replace it with $*. This fixes stem
728 triple expansion bug.
730 2005-03-01 Paul D. Smith <psmith@gnu.org>
732 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
733 on Windows, as it takes a handle not a pid. Just exit.
734 Fix from patch #3679, provided by Alessandro Vesely.
736 * configure.in: Update check for sys_siglist[] from autoconf manual.
737 * signame.c (strsignal): Update to use the new autoconf macro.
739 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
741 * read.c (record_files): Add a check for the list of prerequisites
742 of a static pattern rule being empty. Fixes Savannah bug #12180.
744 2005-02-28 Paul D. Smith <psmith@gnu.org>
746 * doc/make.texi (Text Functions): Update docs to allow the end
747 ordinal for $(wordlist ...) to be 0.
748 * function.c (func_wordlist): Fail if the start ordinal for
749 $(wordlist ...) is <1. Matches documentation.
750 Resolves Savannah support request #103195.
752 * remake.c (update_goal_chain): Fix logic for stopping in -q:
753 previously we were stopping when !-q, exactly the opposite. This
754 has been wrong since version 1.34, in 1994!
755 (update_file): If we got an error don't break out to run more
756 double-colon rules: just return immediately.
757 Fixes Savannah bug #7144.
759 2005-02-27 Paul D. Smith <psmith@gnu.org>
761 * misc.c (end_of_token): Make argument const.
762 * make.h: Update prototype.
764 * function.c (abspath, func_realpath, func_abspath): Use
765 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
766 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
767 * read.c (record_files): Ditto.
768 * variable.c (do_variable_definition): Ditto.
770 * function.c (func_error): Create a new function $(info ...) that
771 simply prints the message to stdout with no extras.
772 (function_table_init): Add new function to the table.
773 * NEWS: Add $(info ...) reference.
774 * doc/make.texi (Make Control Functions): Document it.
776 New feature: if the system supports symbolic links, and the user
777 provides the -L/--check-symlink-time flag, then use the latest
778 mtime between the symlink(s) and the target file.
780 * configure.in (MAKE_SYMLINKS): Check for lstat() and
781 readlink(). If both are available, define MAKE_SYMLINKS.
782 * main.c: New variable: check_symlink_flag.
783 (usage): Add a line for -L/--check-symlink-times to the help string.
784 (switches): Add -L/--check-symlink-times command line argument.
785 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
786 print a warning and disable it again.
787 * make.h: Declare check_symlink_flag.
788 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
789 if the file is a symlink then check each link in the chain and
790 choose the NEWEST mtime we find as the mtime for the file. The
791 newest mtime might be the file itself!
792 * NEWS: Add information about this new feature.
793 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
795 Avoid core dumps described in Savannah bug # 12124:
797 * file.c: New variable snapped_deps remember whether we've run
800 * filedef.h: Extern it.
801 * read.c (record_files): Check snapped_deps; if it's set then
802 we're trying to eval a new target/prerequisite relationship from
803 within a command script, which we don't support. Fatal.
805 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
807 Implementation of the .DEFAULT_TARGET special variable.
809 * read.c (eval): If necessary, update default_target_name when
811 * read.c (record_files): Update default_target_file if
812 default_target_name has changed.
813 * main.c (default_target_name): Define.
814 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
815 default_target_name is set use default_target_file as a root
817 * filedef.h (default_target_name): Declare.
818 * dep.h (free_dep_chain):
819 * misc.c (free_dep_chain): Change to operate on struct nameseq
820 and change name to free_ns_chain.
821 * file.c (snap_deps): Update to use free_ns_chain.
823 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
825 Implementation of the second expansion in explicit rules,
826 static pattern rules and implicit rules.
828 * read.c (eval): Refrain from chopping up rule's dependencies.
829 Store them in a struct dep as a single dependency line. Remove
830 the code that implements SySV-style automatic variables.
832 * read.c (record_files): Adjust the code that handles static
833 pattern rules to expand all percents instead of only the first
834 one. Reverse the order in which dependencies are stored so that
835 when the second expansion reverses them again they appear in
836 the makefile order (with some exceptions, see comments in
837 the code). Remove the code that implements SySV-style automatic
840 * file.c (snap_deps): Implement the second expansion and chopping
841 of dependency lines for explicit rules.
843 * implicit.c (struct idep): Define an auxiliary data type to hold
844 implicit rule's dependencies after stem substitution and
847 * implicit.c (free_idep_chain): Implement.
849 * implicit.c (get_next_word): Implement helper function for
850 parsing implicit rule's dependency lines into words taking
851 into account variable expansion requests. Used in the stem
854 * implicit.c (pattern_search): Implement the second expansion
855 for implicit rules. Also fixes bug #12091.
857 * commands.h (set_file_variables): Declare.
858 * commands.c (set_file_variables): Remove static specifier.
860 * dep.h (free_dep_chain): Declare.
861 * misc.c (free_dep_chain): Implement.
863 * variable.h (variable_expand_for_file): Declare.
864 * expand.c (variable_expand_for_file): Remove static specifier.
866 * make.h (strip_whitespace): Declare.
867 * function.c (strip_whitespace): Remove static specifier.
869 2005-02-26 Paul D. Smith <psmith@gnu.org>
871 * main.c (main): Check for ferror() when reading makefiles from stdin.
872 Apparently some shells in Windows don't close pipes properly and
875 2005-02-24 Jonathan Grant <jg@jguk.org>
877 * configure.in: Add MinGW configuration options, and extra w32 code
879 * Makefile.am: Add MinGW configuration options, and extra w32 code
881 * main.c: Determine correct program string (after last \ without .exe).
882 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
884 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
885 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
886 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
889 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
891 * function.c (func_shell): When initializing error_prefix, check
892 that reading file name is not null. This fixes long-standing
893 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
895 2005-02-09 Paul D. Smith <psmith@gnu.org>
897 * maintMakefile: Update the CVS download URL to simplify them.
898 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
899 downloading the .texi files from Savannah now.
901 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
903 * main.c (handle_non_switch_argument): Only add variables to
904 command_variables if they're not already there: duplicate settings
905 waste space and can be confusing to read.
907 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
908 this header is never included by non-WINDOWS32 code, and it
909 requires <config.h> to define which isn't always included first.
911 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
912 testing MINGW32 versions.
914 * main.c (log_working_directory): flush stdout to be sure the WD
915 change is printed before any stderr messages show up.
917 2005-02-01 Paul D. Smith <psmith@gnu.org>
919 * maintMakefile (po_repo): Update the GNU translation site URL.
921 2004-12-01 Paul D. Smith <psmith@gnu.org>
923 * main.c (main): Change char* env_shell to struct variable shell_var.
924 * variable.c (target_environment): Use new shell_var.
926 2004-11-30 Paul D. Smith <psmith@gnu.org>
928 * configure.in: The old way we avoided creating build.sh from
929 build.sh.in before build.sh.in exists doesn't work anymore; we
930 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
931 the help!). This also keeps automake from complaining.
932 * Makefile.am (README): Add a dummy target so automake won't
933 complain that this file doesn't exist when we checkout from CVS.
934 * maintMakefile (.dep_segment): Rewrite this rule since newer
935 versions of automake don't provide DEP_FILES.
937 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
939 Implementation of `realpath' and `abspath' built-in functions.
941 * configure.in: Check for realpath.
942 * function.c (abspath): Return an absolute file name that does
943 not contain any `.' or `..' components, nor repeated `/'.
944 * function.c (func_abspath): For each name call abspath.
945 * function.c (func_realpath): For each name call realpath
946 from libc or delegate to abspath if realpath is not available.
947 * doc/make.texi (Functions for File Names): Document new functions.
948 * doc/make.texi (Quick Reference): Ditto.
950 2004-11-28 Paul D. Smith <psmith@gnu.org>
952 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
953 arguments. Fixes bug #10252.
955 Fix for bug #1276: Handle SHELL according to POSIX requirements.
957 * main.c (main): Set SHELL to v_noexport by default. Remember the
958 original environment setting of SHELL in the env_shell variable.
959 * main.h: Export new env_shell variable.
960 * variable.c (target_environment): If we find a v_noexport
961 variable for SHELL, add a SHELL variable with the env_shell value.
962 * doc/make.texi (Quick Reference): Document the POSIX behavior.
963 * doc/make.texi (Variables/Recursion): Ditto.
965 2004-11-28 Paul D. Smith <psmith@gnu.org>
967 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
968 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
969 Patch by Alessandro Vesely.
971 2004-11-12 Paul D. Smith <psmith@gnu.org>
973 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
974 the command line if it's inside a string.
975 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
977 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
979 * function.c (func_lastword): New function: return last word
980 from the list of words.
981 * doc/make.texi: Document $(lastword ). Fix broken links in
982 Quick Reference section.
984 2004-10-06 Paul D. Smith <psmith@gnu.org>
986 Apply patch from Alessandro Vesely, provided with bug # 9748.
987 Fix use of tmpnam() to work with Borland C.
989 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
990 construction of a temporary filename, and call new function
991 create_batch_filename().
992 (create_batch_filename) [WINDOWS32]: New function to create a
995 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
997 * read.c (record_target_var): Expand simple pattern-specific
999 * variable.c (initialize_file_variables): Do not expand simple
1000 pattern-specific variable.
1002 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1004 * remake.c (update_file_1): When rebuilding makefiles inherit
1005 dontcare flag from a target that triggered update.
1007 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1009 * variable.c (initialize_file_variables): Mark pattern-specific
1010 variable as a per-target and copy export status.
1012 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1014 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1016 * implicit.c (pattern_search): When considering an implicit rule's
1017 prerequisite check that it is actually a target rather then
1018 just an entry in the file hashtable.
1020 2004-09-21 Paul D. Smith <psmith@gnu.org>
1022 * read.c (readstring): Fix some logic errors in backslash handling.
1023 (eval): Remove some unnecessary processing in buffer handling.
1024 (record_target_var): Assert that parse_variable_definition() succeeded.
1025 Reported by: Markus Mauhart <qwe123@chello.at>.
1027 * misc.c: Removed the sindex() function. All instances of this
1028 function were trivially replaceable by the standard strstr()
1029 function, and that function will always have better (or certainly
1030 no worse) performance than the very simple-minded algorithm
1031 sindex() used. This can matter with complex makefiles.
1032 * make.h: Remove the prototype for sindex().
1033 * function.c (subst_expand): Convert sindex() call to strstr().
1034 This means we no longer need to track the TLEN value so remove that.
1035 (func_findstring): Convert sindex() to strstr().
1036 * commands.c (chop_commands): Convert sindex() calls to strstr().
1037 Suggested by: Markus Mauhart <qwe123@chello.at>.
1039 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1040 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1041 If SHELL is set to CMD.EXE then assume it's batch-mode and
1042 non-unixy. I wrote the code differently from the patch, though,
1043 to make it safer. This also resolves bug #9174.
1045 2004-09-20 Paul D. Smith <psmith@gnu.org>
1047 * expand.c (variable_expand_string): Modify to invoke
1048 patsubst_expand() instead of subst_expand(); the latter didn't
1049 handle suffix patterns correctly.
1050 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1051 was used only from variable_expand_string() and is no longer used
1053 (func_subst): Ditto, on call to subst_expand().
1054 (patsubst_expand): Require the percent pointers to point to the
1055 character after the %, not to the % itself.
1056 * read.c (record_files): New call criteria for patsubst_expand().
1057 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1058 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1060 2004-09-19 Paul D. Smith <psmith@gnu.org>
1062 * function.c (subst_expand): Fix a check in by_word: look for a
1063 previous blank if we're beyond the beginning of the string, not
1064 the beginning of the word.
1065 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1067 2004-05-16 Paul D. Smith <psmith@gnu.org>
1069 * remake.c (update_goal_chain): Change the argument specifying
1070 whether we're rebuilding makefiles to be a global variable,
1071 REBUILDING_MAKEFILES.
1072 (complain): Extract the code that complains about no rules to make
1073 a target into a separate function.
1074 (update_file_1): If we tried to rebuild a file during the makefile
1075 rebuild phase and it was dontcare, then no message was printed.
1076 If we then try to build the same file during the normal build,
1077 print a message this time.
1078 (remake_file): Don't complain about un-remake-able files when
1079 we're rebuilding makefiles.
1081 2004-05-11 Paul D. Smith <psmith@gnu.org>
1083 * job.c (construct_command_argv_internal): OS/2 patches from
1084 Andreas Buening <andreas.buening@nexgo.de>.
1086 2004-05-10 Paul D. Smith <psmith@gnu.org>
1088 * remake.c (update_file): Don't walk the double-colon chain unless
1089 this is a double-colon rule. Fix suggested by Boris Kolpackov
1090 <boris@kolpackov.net>.
1092 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1093 * readme.vms: New section describing OpenVMS support and issues.
1094 * default.c (default_variables): Add support for IA64.
1095 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1096 without some privilege aborts make with the error
1097 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1098 pressing Ctrl+Y and the input device is no terminal. The change
1099 catches this error and just continues.
1101 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1103 2004-04-25 Paul D. Smith <psmith@gnu.org>
1105 * commands.c (set_file_variables): Set $< properly in the face of
1106 order-only prerequisites.
1107 Patch from Boris Kolpackov <boris@kolpackov.net>
1109 2004-04-21 Bob Byrnes <byrnes@curl.com>
1111 * main.c (main): Notice failures to remake makefiles.
1113 2004-03-28 Paul D. Smith <psmith@gnu.org>
1115 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1117 * job.c: No default shell for RISC OS.
1118 (load_too_high): Hard-code the return to 1.
1119 (construct_command_argv_internal): No sh_chars or sh_cmds.
1120 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1122 2004-03-20 Paul D. Smith <psmith@gnu.org>
1124 * variable.c (do_variable_definition): Don't append from the
1125 global set if a previous non-appending target-specific variable
1126 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1129 * expand.c (reference_variable): Don't give up on variables with
1130 no value that have the target-specific append flag set: they might
1131 have a value after all. Reported by Oliver Schmidt
1132 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1133 <nikulin@dx1cmd.inp.nsk.su>.
1135 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1136 refer to absolute pathnames in directories that don't exist: some
1137 portion of the makefile could create those directories before we
1138 match the pattern. Fixes bugs #775 and #108.
1140 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1142 * main.c (main): Free makefile_mtimes if we have any.
1143 * README.W32.template: Update documentation for the current status
1144 of the MS-Windows port.
1145 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
1146 environment variable is sometimes already defined which causes the
1148 * main.c (debug_signal_handler): Only define this function if
1149 SIGUSR1 is available.
1151 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
1153 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
1154 * README.OS2.template: Documentation updates.
1155 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
1156 link line for safety.
1157 * maintMakefile (build.sh.in): Remove an extraneous ")".
1158 * job.c (child_execute_job): Close saved FDs.
1159 * job.c (exec_command) [OS/2]: exec_command(): If the command
1160 can't be exec'ed and if the shell is not Unix-sh, then try again
1161 with argv = { "cmd", "/c", ... }. Normally, this code is never
1162 reached for the cmd shell unless the command really doesn't exist.
1163 (construct_command_argv_internal) [OS/2]: The code for cmd
1164 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
1165 The CMD builtin commands are case insensitive so use strcasecmp().
1167 2004-03-19 Paul D. Smith <psmith@gnu.org>
1169 * read.c (do_define): Re-order line counter increment so the count
1170 is accurate (we were losing one line per define). Reported by
1171 Dave Yost <Dave@Yost.com>.
1173 2004-03-06 Paul D. Smith <psmith@gnu.org>
1175 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
1177 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
1178 * misc.c (message,error,fatal): Ditto.
1179 * configh.dos.template: Define HAVE_ANSI_COMPILER.
1180 * config.h.W32.template: Ditto.
1181 * config.h-vms.template: Ditto.
1182 * config.ami.template: Ditto.
1184 2004-03-04 Paul D. Smith <psmith@gnu.org>
1186 * README.template: Add a note about broken /bin/sh on SunOS
1187 4.1.3_U1 & 4.1.4. Fix up Savannah links.
1189 * misc.c (message, error, fatal): Don't use "..." if we're using
1190 varargs. ansi2knr should handle this but it doesn't work: it
1191 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
1192 done. On many systems (SunOS for example) va_dcl is a #define.
1193 So, force the use of the non-"..." version on pre-ANSI compilers.
1195 * maintMakefile (sign-dist): Create some rules to help automate
1196 the new GNU ftp upload method.
1198 2004-02-24 Paul D. Smith <psmith@gnu.org>
1200 * config.h.W32.template: Add HAVE_STDARG_H
1201 * config.h-vms.template: Ditto.
1202 * config.ami.template: Ditto.
1204 2004-02-23 Jonathan Grant <jg-make@jguk.org>
1206 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
1207 * build_w32.bat: Remove extra "+".
1209 2004-02-23 Paul D. Smith <psmith@gnu.org>
1211 * make.h: Create an UNUSED macro to mark unused parameters.
1212 * (many): Clean up warnings by applying UNUSED, fixing
1213 signed/unsigned incompatibilities, etc.
1215 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
1217 * filedef.h: Name the command_state enumeration.
1218 * file.c (set_command_state): Use the enumeration in the function
1221 * configure.in: Explicitly set SET_MAKE to empty, to disable
1222 MAKE=make even when no make already exists. Fix bug #3823.
1224 2004-02-22 Paul D. Smith <psmith@gnu.org>
1226 * maintMakefile: Perl script to clean up all non-CVS files. Use
1227 it on all the subdirectories for the cvs-clean target.
1229 * main.c (decode_switches): Require non-empty strings for all our
1230 string command-line options. Fixes Debian bug # 164165.
1232 * configure.in: Check for stdarg.h and varargs.h.
1233 * make.h (USE_VARIADIC): Set this if we can use variadic functions
1234 for printing messages.
1235 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
1240 A number of patches for OS/2 support from Andreas Buening
1241 <andreas.buening@nexgo.de>:
1243 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
1244 disable the SIGCHLD handler.
1245 (reap_children) [OS/2]: Remove special handling of job_rfd.
1246 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
1247 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
1248 * main.c (main) [OS/2]: Special handling for paths in OS/2.
1249 * configure.in [OS/2]: Force SA_RESTART for OS/2.
1250 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
1253 2004-02-21 Paul D. Smith <psmith@gnu.org>
1255 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
1256 <mail@kristov.de> reports that if process_begin() fails we don't
1257 handle the error condition correctly in all cases.
1258 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
1259 to have a newline on the message.
1261 * job.c (construct_command_argv_internal): Add "test" to UNIX
1262 sh_cmds[]. Fixes Savannah bug # 7606.
1264 2004-02-04 Paul D. Smith <psmith@gnu.org>
1266 * job.c (vms_handle_apos) [VMS]: Fix various string handling
1267 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
1268 Hartmut Becker <Hartmut.Becker@hp.com>.
1270 2004-01-21 Paul D. Smith <psmith@gnu.org>
1272 * job.c (load_too_high): Implement an algorithm to control the
1273 "thundering herd" problem when using -l to control job creation
1274 via the load average. The system only recomputes the load once a
1275 second but we can start many jobs in a second. To solve this we
1276 keep track of the number of jobs started in the last second and
1277 apply a weight to try to guess what a correct load would be.
1278 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
1279 Also fixes bug #4693.
1280 (reap_children): Decrease the job count for this second.
1281 (start_job_command): Increase the job count for this second.
1283 * read.c (conditional_line): Expand the text after ifn?def before
1284 checking to see if it's a single word. Fixes bug #7257.
1286 2004-01-09 Paul D. Smith <psmith@gnu.org>
1288 * file.c (print_file): Recurse to print all targets in
1289 double-colon rules. Fixes bug #4518, reported (with patch) by
1290 Andrew Chatham <chatham@google.com>.
1292 2004-01-07 Paul D. Smith <psmith@gnu.org>
1294 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
1295 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
1296 AC_FUNC_SETVBUF_REVERSED.
1298 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
1299 (MAKE Variable): Fix Savannah bug #4898.
1301 * job.c (construct_command_argv_internal): Add "!" to the list of
1302 shell escape chars. POSIX sh allows it to appear before a
1303 command, to negate the exit code. Fixes bug #6404.
1305 * implicit.c (pattern_search): When matching an implicit rule,
1306 remember which dependencies have the ignore_mtime flag set.
1307 Original fix provided in Savannah patch #2349, by Benoit
1308 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
1310 2003-11-22 Paul D. Smith <psmith@gnu.org>
1312 * README.W32.template (Outputs): Clarification on -j with
1313 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
1316 2003-11-02 Paul D. Smith <psmith@gnu.org>
1318 * function.c (func_if): Strip all the trailing whitespace from the
1319 condition, then don't expand it. Fixed bug # 5798.
1321 * expand.c (recursively_expand_for_file): If we're expanding a
1322 variable with no file context, then use the variable's context.
1325 2003-10-21 Paul D. Smith <psmith@gnu.org>
1327 * main.c (log_working_directory): Add newlines to printf()s.
1329 * README.cvs: Add a note to ignore warnings during autoreconf.
1331 * maintMakefile (po_repo): Set a new URL for PO file updates.
1332 (get-config/config.guess get-config/config.sub): Get these files
1333 from the Savannah config project instead of ftp.gnu.org.
1335 2003-10-05 Paul Eggert <eggert@twinsun.com>
1337 * main.c (main): Avoid potential subscript error if environ has
1340 2003-08-22 Paul D. Smith <psmith@gnu.org>
1342 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
1343 systems which don't yet implement the C89 standard :-/.
1345 2003-07-18 Paul D. Smith <psmith@gnu.org>
1347 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
1348 [WINDOWS32]: Initialize hash.
1350 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
1352 * dir.c (read_dirstream): Provide a workaround for broken versions of
1353 the MinGW dirent structure.
1355 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1357 * w32/include/dirent.h: Add __MINGW32__ filter.
1359 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1361 * make.h: Add global declaration of *make_host.
1362 * main.c (print_usage): Remove local declaration of *make_host.
1363 (print_version): Display "This program built for ..." after Copyright
1366 2003-05-30 Earnie Boyd <earnie@users.sf.net>
1368 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
1369 execution of "makeinfo --html make.texi".
1371 2003-04-30 Paul D. Smith <psmith@gnu.org>
1373 * build.template: Make some changes to maybe allow this script to
1374 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
1376 * README.OS2.template: New file for OS/2 support. Original
1377 contributed by Andreas Buening.
1378 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
1381 2003-04-19 Paul D. Smith <psmith@gnu.org>
1383 Fix bug #1405: allow a target to match multiple pattern-specific
1386 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
1387 variable.c, where they've always belonged.
1388 * rule.h: Move the prototypes and struct pattern_var as well.
1389 * variable.c (initialize_file_variables): Invoke
1390 lookup_pattern_var() in a loop, until no more matches are found.
1391 If a match is found, create a new variable set for the target's
1392 pattern variables. Then merge the contents of each matching
1393 pattern variable set into the target's pattern variable set.
1394 (lookup_pattern_var): Change this function to be usable
1395 in a loop. It takes a starting position: if NULL, start at the
1396 beginning; if non-NULL, start with the pattern variable after that
1397 position, and return the next matching pattern.
1398 (create_pattern_var): Create a unique instance of
1399 pattern-specific variables for every definition in the makefile.
1400 Don't combine the same pattern together. This allows us to
1401 process the variable handling properly even when the same pattern
1402 is used multiple times.
1403 (parse_variable_definition): New function: break out the parsing
1404 of a variable definition line from try_variable_definition.
1405 (try_variable_definition): Call parse_variable_definition to
1407 (print_variable_data_base): Print out pattern-specific variables.
1408 * variable.h (struct variable): Remember when a variable is
1409 conditional. Also remember its flavor.
1410 (struct pattern_var): Instead of keeping a variable set, we just
1411 keep a single variable for each pattern.
1412 * read.c (record_target_var): Each pattern variable contains only a
1413 single variable, not a set, so create it properly.
1414 * doc/make.texi (Pattern-specific): Document the new behavior.
1416 2003-04-17 Paul D. Smith <psmith@gnu.org>
1418 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
1419 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
1420 file/directory naming rules for VMS so I can't tell whether this
1423 2003-04-09 Paul D. Smith <psmith@gnu.org>
1425 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
1426 DOS-style pathnames: backslash separators and drive specifiers.
1428 2003-03-28 Paul D. Smith <psmith@gnu.org>
1430 * file.c (snap_deps): If .SECONDARY with no targets is given, set
1431 the intermediate flag on all targets. Fixes bug #2515.
1433 2003-03-24 Paul D. Smith <psmith@gnu.org>
1435 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
1436 Upgrade to autoconf 2.57 and automake 1.7.3.
1438 * job.c: More OS/2 changes from Andreas Buening.
1440 * file.c (print_file): Fix variable initialization.
1443 * remake.c (notice_finished_file):
1445 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
1446 some calls (like readdir()) return NULL in valid situations
1447 without resetting errno. Fixes bug #2846.
1449 2003-02-25 Paul D. Smith <psmith@gnu.org>
1451 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
1453 * job.c (_is_unixy_shell) [OS/2]: New function.
1454 Set default shell to /bin/sh.
1455 (reap_children): Close the job_rfd pipe here since we don't use a
1457 (set_child_handler_action_flags): define this to empty on OS/2.
1458 (start_job_command): Close the jobserver pipe and use
1459 child_execute_job() instead of fork/exec.
1460 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
1461 rather than exec'ing, then reconfigure stdin/stdout.
1462 (exec_command): Rewrite to use spawn instead of exec. Return the
1465 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1466 in DOS. Handle the TEMP environment variable as in DOS. Don't
1467 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1468 use -j in DOS mode. Use child_execute_job() instead of
1471 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1474 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1475 prototypes that return values.
1477 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1479 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1480 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1482 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1485 2003-02-24 Paul D. Smith <psmith@gnu.org>
1487 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1488 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1489 (child_execute_job) [VMS]: Handle error status properly.
1490 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1492 * function.c (func_shell): Use EINTRLOOP() while reading from the
1493 subshell pipe (Fixes bug #2502).
1494 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1496 * main.c (main): Ditto.
1498 2003-01-30 Paul D. Smith <psmith@gnu.org>
1500 * read.c (eval): eval() was not fully reentrant, because the
1501 collapsed buffer was static. Change it to be an automatic
1502 variable so that eval() can be invoked recursively.
1504 (eval): Apply patch # 1022: fix memory reference error on long
1505 target-specific variable lines.
1506 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1508 * function.c (check_numeric): Combine the is_numeric() function
1509 into this function, since it's only called from one place.
1510 Constify this function. Have it print the incorrect string in the
1511 error message. Fixes bug #2407.
1512 (strip_whitespace): Constify.
1513 (func_if): Constify.
1514 * expand.c (expand_argument): Constify.
1516 2003-01-29 Paul D. Smith <psmith@gnu.org>
1518 Fix bug # 2169, also reported by other people on various systems.
1520 * make.h: Some systems, such as Solaris and PTX, do not fully
1521 implement POSIX-compliant SA_RESTART functionality; important
1522 system calls like stat() and readdir() can still fail with EINTR
1523 even if SA_RESTART has been set on the signal handler. So,
1524 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1525 EINTR for system calls which return -1 or 0 (NULL), respectively,
1527 Also, remove the old atomic_stat()/atomic_readdir() and
1528 HAVE_BROKEN_RESTART handling.
1530 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1532 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1533 * remake.c (touch_file): Ditto.
1535 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1536 * read.c (construct_include_path): Ditto.
1537 * remake.c (name_mtime): Ditto.
1538 * vpath.c (selective_vpath_search): Ditto.
1539 * dir.c (find_directory): Ditto.
1540 (local_stat): Ditto.
1541 (find_directory): Use ENULLLOOP() to wrap opendir().
1542 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1544 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1545 atomic_readdir() handling.
1547 2003-01-22 Paul D. Smith <psmith@gnu.org>
1549 * function.c (func_call): Fix Bug #1744. If we're inside a
1550 recursive invocation of $(call ...), mask any of the outer
1551 invocation's arguments that aren't used by this one, so that this
1552 invocation doesn't "inherit" them accidentally.
1554 2002-12-05 Paul D. Smith <psmith@gnu.org>
1556 * function.c (subst_expand): Valery Khamenia reported a
1557 pathological performance hit when doing substitutions on very
1558 large values with lots of words: turns out we were invoking
1559 strlen() a ridiculous number of times. Instead of having each
1560 call to sindex() call strlen() again, keep track of how much of
1561 the text we've seen and pass the length to sindex().
1563 2002-11-19 Paul D. Smith <psmith@gnu.org>
1565 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1568 2002-11-16 Paul D. Smith <psmith@gnu.org>
1570 * NMakefile.template (OBJS): Add hash.c object file.
1571 * SMakefile.template (srcs): Ditto.
1572 * Makefile.ami (objs): Ditto.
1573 * build_w32.bat: Ditto.
1575 * Makefile.DOS.template: Remove extra dependencies.
1577 2002-10-25 Paul D. Smith <psmith@gnu.org>
1579 * expand.c (install_variable_buffer): New function. Install a new
1580 variable_buffer context and return the previous one.
1581 (restore_variable_buffer): New function. Free the current
1582 variable_buffer context and put a previously saved one back.
1583 * variable.h: Prototypes for {install,restore}_variable_buffer.
1584 * function.c (func_eval): Push a new variable_buffer context
1585 before we eval, then restore the old one when we're done.
1588 * read.c (install_conditionals): New function. Install a new
1589 conditional context and return the previous one.
1590 (restore_conditionals): New function. Free the current
1591 conditional context and put a previously saved one back.
1592 (eval): Use the {install,restore}_conditionals for "include"
1594 (eval_buffer): Use {install,restore}_conditionals to preserve the
1595 present conditional state before we evaluate the buffer.
1598 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1600 (Recursion): Add a variable index entry for CURDIR.
1602 * README.cvs: Update to appropriate versions.
1603 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1604 don't need to copy loadavg.c: automake is smart enough to create
1605 it for me. Still have a bug in automake related to ansi2knr tho.
1607 2002-10-14 Paul D. Smith <psmith@gnu.org>
1609 * remake.c (notice_finished_file): Only touch targets if they have
1610 at least one command (as per POSIX). Resolve Bug #1418.
1612 * *.c: Convert to using ANSI C-style function definitions.
1613 * Makefile.am: Enable the ansi2knr feature of automake.
1614 * configure.in: ditto.
1616 2002-10-13 Paul D. Smith <psmith@gnu.org>
1618 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1619 for automatic variable values like $^, etc. In the case of very
1620 large lists of prerequisites this causes problems. Instead reuse
1621 a static buffer (resizeable) for each variable.
1623 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1624 target-specific variable definitions. Check for it and set an
1626 (record_target_var): Set the export field to v_export if the
1627 "exported" flag is set.
1628 * doc/make.texi (Target-specific): Document the ability to use
1631 * doc/make.texi: Change the name of the section on automatic
1632 variables from "Automatic" to "Automatic Variables". Added text
1633 clarifying the scope of automatic variables.
1635 2002-10-04 Paul D. Smith <psmith@gnu.org>
1637 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1639 (record_files): Ditto.
1641 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1642 the search for the '=' to only within the enclosing parens.
1644 2002-10-03 Paul D. Smith <psmith@gnu.org>
1646 Version 3.80 released.
1648 * dir.c: Change hash functions to use K&R function definition style.
1649 * function.c: Ditto.
1651 * variable.c: Ditto.
1653 Update to automake 1.7.
1655 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1656 (pdf): Remove this target as automake now provides one.
1658 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1660 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1662 * makefile.com: Updates for GNU make 3.80.
1663 * makefile.vms: Ditto.
1665 2002-09-23 Paul D. Smith <psmith@gnu.org>
1667 * read.c (enum make_word_type): Remove w_comment.
1668 (get_next_mword): Don't treat comment characters as special; where
1669 this function is used we will never see a comment (it's stripped
1670 before we get here) and treating comments specially means that
1671 targets like "foo\#bar" aren't handled properly.
1673 2002-09-18 Paul D. Smith <psmith@gnu.org>
1675 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1677 * read.c (eval): Expansion of arguments to export/unexport was
1678 ignoring all arguments after the first one. Change the algorithm
1679 to expand the whole line once, then parse the results.
1681 2002-09-17 Paul D. Smith <psmith@gnu.org>
1683 Fix Bug #940 (plus another bug I found while looking at this):
1685 * read.c (record_target_var): enter_file() will add a new entry if
1686 it's a double-colon target: we don't want to do that in this
1687 situation. Invoke lookup_file() and only enter_file() if it does
1688 not already exist. If the file we get back is a double-colon then
1689 add this variable to the "root" double-colon target.
1691 * variable.c (initialize_file_variables): If this file is a
1692 double-colon target but is not the "root" target, then initialize
1693 the root and make the root's variable list the parent of our
1696 2002-09-13 Paul D. Smith <psmith@gnu.org>
1698 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1700 * hash.c (round_up_2): Get rid of a warning.
1702 2002-09-12 Paul D. Smith <psmith@gnu.org>
1704 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1705 so it doesn't complain about getloadavg.c.
1707 * commands.c (set_file_variables): Make sure we always alloca() at
1708 least 1 character for the value of $? (for '\0').
1710 2002-09-11 Paul D. Smith <psmith@gnu.org>
1712 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1713 macro to use RESULT instead of the incorrect _RESULT_.
1715 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1716 and atomic_readdir(). We need to #include dirent.h to get this to
1718 * misc.c (atomic_readdir): Fix typos.
1720 2002-09-10 Paul D. Smith <psmith@gnu.org>
1722 * read.c (eval): Expand variable lists given to export and
1723 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1724 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1726 * doc/make.texi (Variables/Recursion): Document this.
1727 (Conditional Syntax): And here.
1729 2002-09-09 Paul D. Smith <psmith@gnu.org>
1731 * configure.in: Check for memmove().
1733 2002-09-07 Paul D. Smith <psmith@gnu.org>
1735 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1736 Michael Sterrett <msterret@coat.com> reports that while it has
1737 SA_RESTART, it does not work properly.
1739 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1740 that invokes stat() and loops to do it again if it returns EINTR.
1741 (atomic_readdir): Ditto, with readdir().
1743 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1744 and readdir() to atomic_stat() and atomic_readdir().
1746 2002-09-04 Paul D. Smith <psmith@gnu.org>
1748 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
1749 reports that GNU make sometimes doesn't recognize that targets can
1750 be made, when directories can be created as prerequisites. He
1751 reports that changing the order of predicates in the DEP->changed
1752 flag test so that lookup_file() is always performed, solves this
1755 2002-08-08 Paul D. Smith <psmith@gnu.org>
1757 * configure.in: Require a newer version of gettext.
1759 * misc.c (perror_with_name): Translate the format string (for
1760 right-to-left language support).
1761 (pfatal_with_name): Ditto.
1763 * main.c: Create a static array of strings to store the usage
1764 text. This is done to facilitate translations.
1765 (struct command_switch): Remove argdesc and description fields.
1766 (switches): Remove values for obsolete fields.
1767 (print_usage): Print each element of the usage array.
1769 * hash.c: Change function definitions to be K&R style.
1771 2002-08-02 Paul D. Smith <psmith@gnu.org>
1773 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
1774 this one because it's too hard to get right. We'll look at it for
1776 * main.c (main): Don't create the .TARGETS variable.
1777 * variable.c (handle_special_var): Don't handle .TARGETS.
1779 2002-08-01 Paul D. Smith <psmith@gnu.org>
1781 * main.c (switches): Add a new option, -B (--always-make). If
1782 specified, make will rebuild all targets that it encounters even
1783 if they don't appear to be out of date.
1784 (always_make_flag): New flag.
1785 * make.h: Extern always_make_flag.
1786 * remake.c (update_file_1): Check always_make_flag; if it's set we
1787 will always rebuild any target we can, even if none of its
1788 prerequisites are newer.
1791 * doc/make.texi (Shell Function): Make it clear that make
1792 variables marked as "export" are not passed to instances of the
1795 Add new introspection variable .VARIABLES and .TARGETS.
1797 * variable.c (handle_special_var): New function. If the variable
1798 reference passed in is "special" (.VARIABLES or .TARGETS),
1799 calculate the new value if necessary. .VARIABLES is handled here:
1800 walk through the hash of defined variables and construct a value
1801 which is a list of the names. .TARGETS is handled by
1802 build_target_list().
1803 (lookup_variable): Invoke handle_special_var().
1804 * file.c (build_target_list): Walk through the hask of known files
1805 and construct a list of the names of all the ones marked as
1807 * main.c (main): Initialize them to empty (and as simple variables).
1808 * doc/make.texi (Special Variables): Document them.
1809 * NEWS: Mention them.
1811 * variable.h (struct variable): Add a new flag "exportable" which
1812 is true if the variable name is valid for export.
1813 * variable.c (define_variable_in_set): Set "exportable" when a new
1814 variable is defined.
1815 (target_environment): Use the "exportable" flag instead of
1816 re-checking the name here... an efficiency improvement.
1818 2002-07-31 Paul D. Smith <psmith@gnu.org>
1820 * config.h-vms.template: Updates to build on VMS. Thanks to
1821 Brian_Benning@aksteel.com for helping verify the build.
1822 * makefile.com: Build the new hash.c file.
1823 * hash.h: Use strcpmi(), not stricmp(), in the
1824 HAVE_CASE_INSENSITIVE_FS case.
1826 2002-07-30 Paul D. Smith <psmith@gnu.org>
1828 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
1829 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
1830 Reported by <Brian_Benning@aksteel.com>.
1832 2002-07-10 Paul D. Smith <psmith@gnu.org>
1834 * variable.c (pop_variable_scope): Remove variable made unused by
1835 new hash infrastructure.
1836 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
1837 comparisons as well as name comparisons.
1838 * variable.h: Add a prototype for new hash_init_function_table().
1839 * file.c (lookup_file): Remove variables made unused by new hash
1841 * dir.c (directory_contents_hash_2): Missing return of hash value.
1842 (dir_contents_file_exists_p): Remove variables made unused by new
1843 hash infrastructure.
1846 Installed Greg McGary's integration of the hash functions from the
1847 GNU id-utils package:
1849 2002-07-10 Greg McGary <greg@mcgary.org>
1851 * scripts/functions/filter-out: Add literals to to the
1852 pattern space in order to add complexity, and trigger
1853 use of an internal hash table. Fix documentation strings.
1854 * scripts/targets/INTERMEDIATE: Reverse order of files
1855 passed to expected `rm' command.
1857 2002-07-10 Greg McGary <greg@mcgary.org>

1949 2002-07-10 Paul D. Smith <psmith@gnu.org>
1951 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
1952 prerequisite list. A real SysV make will expand the entire
1953 prerequisites list _twice_: we don't do that as it's a big
1954 backward-compatibility problem. We only replace those specific
1957 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
1958 references left in the list of prerequisites. Check for .POSIX as
1959 we record targets, so we can disable non-POSIX behavior while
1960 reading makefiles as well as running them.
1961 (eval): Check the prerequisite list to see if we have anything
1962 that looks like a SysV prerequisite variable reference.
1964 2002-07-09 Paul D. Smith <psmith@gnu.org>
1966 * doc/make.texi (Prerequisite Types): Add a new section describing
1967 order-only prerequisites.
1969 * read.c (uniquize_deps): If we have the same file as both a
1970 normal and order-only prereq, get rid of the order-only prereq,
1971 since the normal one supersedes it.
1973 2002-07-08 Paul D. Smith <psmith@gnu.org>
1975 * AUTHORS: Added Greg McGary to the AUTHORS file.
1976 * NEWS: Blurbed order-only prerequisites.
1977 * file.c (print_file): Show order-only deps properly when printing
1980 * maintMakefile: Add "update" targets for wget'ing the latest
1981 versions of various external files. Taken from Makefile.maint in
1984 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1985 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1987 2002-07-07 Paul D. Smith <psmith@gnu.org>
1989 * po/*.po: Remove. We'll use wget to retrieve them at release
1992 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1993 rather than a shell you get an exception. Make sure we look up
1994 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1996 * remake.c (notice_finished_file): Fix handling of -t flag.
1997 Patch provided by Henning Makholm <henning@makholm.net>.
1999 * implicit.c (pattern_search): Some systems apparently run short
2000 of stack space, and using alloca() in this function caused an
2001 overrun. I modified it to use xmalloc() on the two variables
2002 which seemed like they might get large. Fixes Bug #476.
2004 * main.c (print_version): Update copyright notice to conform with
2006 (print_usage): Update help output.
2008 * function.c (func_eval): Create a new make function, $(eval
2009 ...). Expand the arguments, put them into a buffer, then invoke
2010 eval_buffer() on the resulting string.
2011 (func_quote): Create a new function, $(quote VARNAME). Inserts
2012 the value of the variable VARNAME without expanding it any
2015 * read.c (struct ebuffer): Change the linebuffer structure to an
2016 "eval buffer", which can be either a file or a buffer.
2017 (eval_makefile): Move the code in the old read_makefile() which
2018 located a makefile into here: create a struct ebuffer with that
2019 information. Have it invoke the new function eval() with that
2021 (eval_buffer): Create a new function that creates a struct ebuffer
2022 that holds a string buffer instead of a file. Have it invoke
2023 eval() with that ebuffer.
2024 (eval): New function that contains the guts of the old
2025 read_makefile() function: this function parses makefiles. Obtains
2026 data to parse from the provided ebuffer. Some modifications to
2027 make the flow of the function cleaner and clearer. Still could
2028 use some work here...
2029 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2030 contents of the define/endef variable from the ebuffer.
2031 (readstring): Read the next line from a string-style ebuffer.
2032 (readline): Read the next line from an ebuffer. If it's a string
2033 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2036 * dep.h (eval_buffer): Prototype eval_buffer();
2038 * variable.c (do_variable_definition): Make sure that all
2039 non-target-specific variables are registered in the global set.
2040 If we're invoked from an $(eval ...) we might be inside a $(call
2041 ...) or other function which has pushed a variable scope; we still
2042 want to define our variables from evaluated makefile code in the
2045 2002-07-03 Greg McGary <greg@mcgary.org>
2047 * dep.h (struct dep) [ignore_mtime]: New member.

2052 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2053 (read_makefile): Parse '|' in prerequisite list.
2054 (uniquize_deps): Consider ignore_mtime when comparing deps.
2055 * remake.c (update_file_1, check_dep): Don't force remake for
2056 dependencies that have d->ignore_mtime.
2057 * commands.c (FILE_LIST_SEPARATOR): New constant.
2058 (set_file_variables): Don't include a
2059 prerequisite in $+, $^ or $? if d->ignore_mtime.
2062 2002-06-18 Paul D. Smith <psmith@gnu.org>
2064 * make.texinfo: Updates for next revision. New date/rev/etc.
2065 Recreate all Info menus. Change license on the manual to the GNU
2066 Free Documentation License. A number of typos.
2067 (Variables Simplify): Don't use "-" before it's defined.
2068 (Automatic Prerequisites): Rewrite the target example to work
2069 properly if the compile fails. Remove incorrect comments about
2070 how "set -e" behaves.
2071 (Text Functions): Move the "word", "wordlist", "words", and
2072 "firstword" functions here, from "File Name Functions".
2073 * make-stds.texi: Update from latest GNU version.
2074 * fdl.texi: (created) Import the latest GNU version.
2076 2002-06-06 Paul D. Smith <psmith@gnu.org>
2078 * variable.c (do_variable_definition): New function: extract the
2079 part of try_variable_definition() that actually sets the value
2080 into a separate function.
2081 (try_variable_definition): Call do_variable_definition() after
2082 parsing the variable definition string.
2083 (define_variable_in_set): Make the name argument const.
2085 * variable.h (enum variable_flavor): Make public.
2086 (do_variable_definition): Create prototype.
2088 * read.c (read_all_makefiles): Create a new built-in variable,
2090 (read_makefile): Add each makefile read in to this variable value.
2092 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2094 * Makefile.DOS.template: Tweak according to changes in the
2095 distribution. Add back the dependencies of *.o files.
2097 * configh.dos.template: Synchronize with config.h.in.
2099 2002-05-09 Paul D. Smith <psmith@gnu.org>
2101 * file.c (file_timestamp_now): Use K&R function declaration.
2103 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2104 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2105 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2106 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2107 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2108 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2109 nlist.n_name is a pointer rather than an array.
2111 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2112 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2113 * configure.in: Use it instead of the old version.
2115 * main.c (main): Prefer setvbuf() to setlinebuf().
2117 2002-05-08 Paul D. Smith <psmith@gnu.org>
2119 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2120 (loadavg_LDADD): Ditto.
2122 2002-04-29 Paul D. Smith <psmith@gnu.org>
2124 * expand.c (recursively_expand_for_file): Rename
2125 recursively_expand() to recursively_expand_for_file() and provide
2126 an extra argument, struct file. If the argument is provided, set
2127 the variable scope to that of the file before expanding.
2128 * variable.h (recursively_expand): Make this a macro that invokes
2129 recursively_expand_for_file() with a NULL file pointer.
2130 * variable.c (target_environment): Call the renamed function and
2131 provide the current file context.
2132 Fixes Debian bug #144306.
2134 2002-04-28 Paul D. Smith <psmith@gnu.org>
2136 Allow $(call ...) user-defined variables to be self-referencing
2137 without throwing an error. Allows implementation of transitive
2138 closures, among other possibly useful things.
2139 Requested by: Philip Guenther <guenther@sendmail.com>
2141 * variable.h (struct variable): Add a new field: exp_count, and
2142 new macros to hold its size and maximum value.
2143 (warn_undefined): Make this a macro.
2144 * variable.c (define_variable_in_set): Initialize it.
2145 * expand.c (recursively_expand): If we detect recursive expansion
2146 of a variable, check the exp_count field. If it's greater than 0
2147 allow the recursion and decrement the count.
2148 (warn_undefined): Remove this (now a macro in variable.h).
2149 * function.c (func_call): Before we expand the user-defined
2150 function, modify its exp_count field to contain the maximum
2151 number of recursive calls we'll allow. After the call, reset it
2154 2002-04-21 Paul D. Smith <psmith@gnu.org>
2156 Modified to use latest autoconf (2.53), automake (1.6.1), and
2157 gettext (0.11.1). We're using gettext's new "external" support,
2158 to avoid including libintl source with GNU make.
2160 * README.cvs: New file. Explain how to build GNU make from CVS.
2162 * configure.in: Modify checking for the system glob library.
2163 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
2164 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
2165 etc. will manage it correctly). Set an automake conditional
2166 USE_LOCAL_GLOB to decide whether to compile the glob library.
2168 * getloadavg.c (main): Include make.h in the "TEST" program to
2171 * Makefile.am: Remove special rules for loadavg. Replace them
2172 with Automake capabilities for building extra programs.
2174 * signame.c: This file does nothing if the system provide
2175 strsignal(). If not, it implements strsignal(). If the system
2176 doesn't define sys_siglist, then we make our own; otherwise we use
2178 * signame.h: Removed.
2180 * main.c (main): No need to invoke signame_init(). Update copyright.
2182 * ABOUT-NLS: Removed.
2183 * gettext.c: Removed.
2184 * gettext.h: Get a simplified copy from the gettext package.
2186 * i18n/*.po: Moved to po/.
2189 * config/*: Created. Contains package configuration helper files.
2190 * config.guess, config.sub: Moved to config directory.
2192 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
2193 Rework to use new-style autoconf features. Use the "external"
2194 mode for gettext. Make the build.sh config file conditional on
2195 whether build.sh.in exists, to avoid autoconf errors.
2196 * acinclude.m4: Removed almost all macros as being obsolete.
2197 Rewrote remaining macros to use AC_DEFINE.
2198 * acconfig.h: Removed.
2200 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
2201 conditional to handle customs support. Remove special handling
2204 2002-04-20 Paul D. Smith <psmith@gnu.org>
2206 * function.c (func_call): Don't mark the argument variables $1,
2207 etc. as recursive. They've already been fully expanded so
2208 there's no need to do it again, and doing so strips escaped $'s.
2209 Reported by Sebastian Glita <glseba@yahoo.com>.
2211 * remake.c (notice_finished_file): Walk through double-colon
2212 entries via the prev field, not the next field!
2213 Reported by Greg McGary <greg@mcgary.org>.
2215 * main.c (main): If the user specifies -q and asks for a specific
2216 target which is a makefile, we got an assert. In that case it
2217 turns out we should continue normally instead.
2219 * i18n/de.po, i18n/fr.po: Installed an updated translation.
2221 * i18n/he.po: Installed a new translation.
2223 2002-01-07 Paul D. Smith <psmith@gnu.org>
2225 * i18n/es.po, i18n/ru.po: Installed an updated translation.
2227 2001-12-04 Paul D. Smith <psmith@gnu.org>
2229 * i18n/ja.po: Installed an updated translation.
2231 2001-09-06 Paul Eggert <eggert@twinsun.com>
2233 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
2234 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
2236 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
2238 (main): Get rid of any avoidable limit on stack size.
2240 2001-09-04 Paul D. Smith <psmith@gnu.org>
2242 * i18n/da.po: Installed an updated translation.
2244 2001-08-03 Paul D. Smith <psmith@gnu.org>
2246 * i18n/fr.po: Installed an updated translation.
2247 Resolves Debian bug #106720.
2249 2001-06-13 Paul D. Smith <psmith@gnu.org>
2251 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
2254 2001-06-11 Paul D. Smith <psmith@gnu.org>
2256 * i18n/ko.po: Installed a new translation.
2258 2001-05-06 Paul D. Smith <psmith@gnu.org>
2260 Modify the EINTR handling.
2262 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
2263 the way in which we manage the file descriptor/signal handler race
2264 trap to be more efficient.
2266 2001-05-06 Paul Eggert <eggert@twinsun.com>
2268 Restart almost all system calls that are interrupted, instead
2269 of worrying about EINTR. The lone exception is the read() for
2272 * configure.in (HAVE_SA_RESTART): New macro.
2273 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
2274 * main.c (main): Use SA_RESTART instead of the old,
2275 nonstandard SA_INTERRUPT.
2277 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
2278 * main.c (bsd_signal): New function or macro,
2279 if the implementation doesn't supply it.
2280 (The bsd_signal function will be in POSIX 1003.1-200x.)
2281 (HANDLESIG): Remove.
2282 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
2284 * make.h (EINTR_SET): Remove.
2285 (SA_RESTART): New macro.
2287 * arscan.c (ar_member_touch): Don't worry about EINTR.
2288 * function.c (func_shell): Likewise.
2289 * job.c (reap_children, free_child, new_job): Likewise.
2290 * main.c (main): Likewise.
2291 * remake.c (touch_file, name_mtime): Likewise.
2293 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
2294 if fstat failed with errno!=EINTR, the error was ignored.
2296 * job.c (set_child_handler_action_flags): New function.
2297 (new_job): Use it to temporarily clear the SIGCHLD action flags
2298 while reading the token.
2300 2001-05-02 Paul D. Smith <psmith@gnu.org>
2302 * job.c (start_job_command): Don't add define/endef per-line flags
2303 to the top-level flags setting.
2305 2001-04-03 Paul D. Smith <psmith@gnu.org>
2307 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
2308 bit on error, so check for odd return values, not non-0 return
2310 (VMS_get_member_info): Calculate the timezone differences correctly.
2311 Reported by John Fowler <jfowler@nyx.net>.
2314 2001-03-14 Paul D. Smith <psmith@gnu.org>
2316 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
2317 value before invoking define_variable().
2318 Reported by John Fowler <jfowler@nyx.net>.
2320 2001-02-07 Paul D. Smith <psmith@gnu.org>
2322 * read.c (record_target_var): If we reset the variable due to a
2323 command-line variable setting overriding it, turn off the "append"
2326 2001-01-17 Paul D. Smith <psmith@gnu.org>
2328 * variable.c (lookup_variable) [VMS]: When getting values from the
2329 environment, allocate enough space for the _value_ plus escapes,
2330 not enough space for the name plus escapes :-/.
2331 Reported by John Fowler <jfowler@nyx.net>.
2333 * remake.c (f_mtime): Removed the "***" prefix from the mod time
2334 warnings that make generates, so it doesn't look like an error.
2335 Reported by Karl Berry <karl@gnu.org>.
2338 Fix for PR/2020: Rework appended target-specific variables. I'm
2339 fairly confident this algorithm is finally correct.
2341 * expand.c (allocated_variable_append): Rewrite. Instead of
2342 expanding each appended variable then adding all the expanded
2343 strings together, we append all the unexpanded values going up
2344 through the variable set contexts, then expand the final result.
2345 This behaves just like non-target-specific appended variable
2346 values, while the old way didn't in various corner cases.
2347 (variable_append): New function: recursively append the unexpanded
2348 value of a variable, walking from the outermost variable scope to
2350 * variable.c (lookup_variable): Remove the code that looked up the
2351 variable set list if the found variable was "append". We don't
2353 (lookup_variable_in_set): Make this non-static so we can use it
2355 (try_variable_definition): Use lookup_variable_in_set() rather
2356 than faking out current_variable_set_list by hand (cleanup).
2357 * variable.h: Add a prototype for the now non-static
2358 lookup_variable_in_set().
2360 2000-11-17 Paul D. Smith <psmith@gnu.org>
2362 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
2363 WINDOWS32 port to assume timestamps can be up to 3 seconds away
2364 before throwing a fit.
2366 2000-11-17 Paul D. Smith <psmith@gnu.org>
2368 * read.c (readline): CRLF calculations had a hole, if you hit the
2369 buffer grow scenario just right. Reworked the algorithm to avoid
2370 the need for len or lastlen at all. Problem description with
2371 sample code chages provided by Chris Faylor <cgf@redhat.com>.
2373 2000-10-24 Paul D. Smith <psmith@gnu.org>
2375 * gettext.c (SWAP): Declare this with the prototype, otherwise
2376 some systems don't work (non-32-bit? Reported for Cray T3E).
2377 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2379 2000-10-05 Paul D. Smith <psmith@gnu.org>
2381 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
2382 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
2384 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2386 2000-09-22 Paul D. Smith <psmith@gnu.org>
2388 * gettext.c: Don't #define _GETTEXT_H here; we only include some
2389 parts of the real gettext.h here, and we expect to really include
2390 the real gettext.h later. If we keep this #define, it's ignored.
2392 2000-09-21 Paul D. Smith <psmith@gnu.org>
2394 * main.c (log_working_directory): Rework the text to use complete
2395 sentences, to make life simpler for the translators.
2397 2000-08-29 Paul D. Smith <psmith@gnu.org>
2399 * file.c (remove_intermediates): Print a debug message before we
2400 remove intermediate files, so the user (if she uses -d) knows
2403 2000-08-21 Paul D. Smith <psmith@gnu.org>
2405 * variable.c (try_variable_definition): Change how we handle
2406 target-specific append variable defns: instead of just setting the
2407 value, expand it as an append _but_ only within the current
2408 target's context. Otherwise we lose all but the last value if the
2409 variable is appended more than once within the current target
2410 context. Fixes PR/1831.
2412 2000-08-16 Paul D. Smith <psmith@gnu.org>
2414 * function.c (func_shell): Nul-terminate the buffer before
2415 printing an exec error message (just in case it's not!).
2416 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2418 2000-07-25 Paul D. Smith <psmith@gnu.org>
2420 * job.c (construct_command_argv_internal): Add "~" to the list of
2421 sh_chars[] which disallow optimizing out the shell call.
2423 2000-07-23 Paul Eggert <eggert@twinsun.com>
2425 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
2426 supersedes --disable-nsec-timestamps.
2427 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
2428 * README: Remove --disable-nsec-timestamps.
2430 * filedef.h (struct file.low_resolution_time): New member.
2431 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
2432 * remake.c (update_file_1):
2433 Avoid spurious rebuilds due to low resolution time stamps,
2434 generalizing the earlier code that applied only to archive members.
2435 (f_mtime): Archive members always have low resolution time stamps.
2437 * configure.in: Remove --disable-nsec-timestamps, as this has
2438 been superseded by .LOW_RESOLUTION_TIME.
2440 2000-07-23 Paul Eggert <eggert@twinsun.com>
2442 * configure.in (enable_nsec_timestamps): Renamed from
2443 make_cv_nsec_timestamps, since enable/disable options
2444 shouldn't be cached.
2446 2000-07-23 Bruno Haible <haible@clisp.cons.org>
2447 and Paul Eggert <eggert@twinsun.com>
2449 * file.c (file_timestamp_now):
2450 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
2451 so that clock_gettime is not linked unless needed.
2453 * filedef.h (FILE_TIMESTAMP_HI_RES):
2454 Remove definition; "configure" now does this.
2456 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
2457 to before high resolution file timestamp check,
2458 since that check now uses uintmax_t.
2459 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
2460 high resolution file timestamps.
2461 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
2462 so that we don't link in clock_gettime unnecessarily.
2464 2000-07-17 Paul D. Smith <psmith@gnu.org>
2466 * i18n/ja.po: New version of the translation file.
2468 2000-07-07 Paul D. Smith <psmith@gnu.org>
2470 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2471 the offset calculation.
2472 (name_mtime): Replace EINTR test with EINTR_SET macro.
2474 2000-07-07 Paul Eggert <eggert@twinsun.com>
2478 * remake.c (update_file_1):
2479 Avoid spurious rebuilds of archive members due to their
2480 timestamp resolution being only one second.
2481 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2482 the clock's resolution being lower than file timestamps'.
2483 When warning about future timestamps, report only the discrepancy,
2484 not the absolute value of the timestamp and the current time.
2486 * file.c (file_timestamp_now): New arg RESOLUTION.
2487 * filedef.h (file_timestamp_now): Likewise.
2488 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2490 2000-07-05 Paul D. Smith <psmith@gnu.org>
2492 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2493 to listp. Fixes PR/1793.
2495 2000-06-26 Paul Eggert <eggert@twinsun.com>
2497 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2499 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2501 * remake.c (f_mtime): Remove unused var memtime.
2503 2000-06-25 Martin Buchholz <martin@xemacs.org>
2505 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2506 Ran spell-check on make.texinfo.
2508 2000-06-23 Paul D. Smith <psmith@gnu.org>
2510 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2511 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2512 * make.h: Define these macros.
2514 * Version 3.79.1 released.
2516 * configure.in: Add a new option, --disable-nsec-timestamps, to
2517 avoid using sub-second timestamps on systems that support it. It
2518 can lead to problems, e.g. if your makefile relies on "cp -p".
2519 * README.template: Document the issue with "cp -p".
2521 * config.guess, config.sub: Updated.
2525 See ChangeLog.2, available in the CVS repository at:
